AN - 69449034; 10709347 AB - Epidemiological studies of the influence of environmental ultraviolet radiation (UVR) in the development of cataract, pterygium, droplet keratopathies and age-related macular degeneration have produced inconsistent findings. The lack of consistent results may be due largely to either incomplete or erroneous estimates of outdoor UV exposure dose. Geometrical factors dominate the determination of UVR exposure of the eye. The degree of lid opening limits ocular exposure to only those rays entering at angles near the horizon. Clouds redistribute overhead UVR to the horizon sky. Mountains, trees and building shield the eye from direct sky exposure. Most ground surfaces reflect little UVR. The result is that the highest UVR exposure occurs during light overcast where the horizon is visible and ground surface reflection is high. By contrast, exposure in a high mountain valley with green foliage results in a much lower ocular dose. Other findings of these studies show that retinal exposure to light and UVR in daylight occurs largely in the superior retina.

AN - 69433155; 10674662 AB - Tick-borne encephalitis (TBE) is a viral illness endemic to the Balkan region. United States military forces were deployed to Bosnia in early 1996 as part of Operation Joint Endeavor, a U.S.-led multinational peace-keeping operation. To counteract the TBE threat, an inactivated, parenteral vaccine (FSME-Immun Inject; Immuno AG, Vienna, Austria) was offered to soldiers at high risk on a volunteer basis in an accelerated, 3-dose schedule (0, 7, and 28 days). Passive adverse reaction surveillance was conducted on 3,981 vaccinated personnel. Paired sera from a randomly selected group of 1,913 deployed personnel (954 who received vaccine and 959 who were unvaccinated) were tested for antibodies to TBE by an ELISA. Three-dose recipients demonstrated an 80% seroconversion rate (4-fold or greater increase in anti-TBE titers). By comparison, the TBE infection rate in the unvaccinated cohort was found to be only 0.42% (4 of 959). Only 0.18% of vaccinees reported self-limited symptoms. An accelerated immunization schedule appears to be an acceptable option for military personnel or travelers on short-term notice to TBE-endemic areas.

AN - 69353921; 10594897 AB - Measurements of the efficacy of novel botulinum toxin antagonists can be based on classical bioassays of toxin concentration. However, the relative sensitivities of in vivo and in vitro assays to the effects of antagonists are not necessarily correlated with the sensitivities of the assays to toxin. Comparisons of the sensitivity of an in vitro mouse muscle contraction assay with an in vivo mouse survival assay indicated that the in vivo assay was more sensitive to botulinum toxin serotype A by more than one order of magnitude at equivalent molar concentrations. However, in studies of toxin neutralization with equine antisera, the in vitro muscle assay was more than three times more sensitive to the presence of antisera than the equivalent mouse survival assay. For the development of new drugs to treat botulism, antagonist sensitivity is a primary consideration in determining relative efficacy during structure-activity studies. Thus, in studies of toxin antagonists, the in vitro assay appears to be superior for initial testing.

AN - 69351059; 10594907 AB - The chloroamide compound 1,3,4,6-tetrachloro-7,8-diphenyl-2, 5-diiminoglycoluril (S-330) was found to be a strong reactant in dermal formulations for the decontamination of sulfur mustard (HD). In this report, we present analytical methodologies applicable to the characterization, purity determination and quantitation of S-330 in bulk material or formulations. High-performance liquid chromatography-mass spectrometry (LC-MS) coupled with atmospheric pressure chemical ionization (APCI) interface or ultraviolet detector and nuclear magnetic spectroscopy (NMR) were used to identify and characterize S-330 and impurities in the synthetic lots or degradation products in formulations. Bulk synthesis using a chlorination process has yielded a product of 90% purity. The major impurity has been separated and identified structurally as the trichloro analog of S-330. Higher purity S-330 can be made using column chromatography, but this does not appear to be economical for large-scale production. Factors affecting the stability of S-330 in topical formulations include water content, pH, alcohols and UV light. Chloroamide S-330 decomposes at 50-60 degrees C and is not amenable for GC analysis. The HPLC technique is superior to NMR or active chlorine assay in the purity determination for S-330 in bulk material or formulations. In topical formulations containing S-330, 5-10% of water can be tolerated, but alcohols and acidic and basic conditions should be avoided.

AN - 69341868; 10585902 AB - The two major threat classes of chemical weapons are mustard gas and the nerve agents, and this has not changed in over 50 years. Both types are commonly called gases, but they are actually liquids that are not remarkably volatile. These agents were designed specifically to harm people by any route of exposure and to be effective at low doses. Mustard gas was used in World War I, and the nerve agents were developed shortly before, during, and after World War II. Our perception of the potency of chemical weapons has changed, as well as our concern over potential effects of prolonged exposures to low doses and potential target populations that include women and children. Many of the toxicologic studies and human toxicity estimates for both mustard and nerve agents were designed for the purpose of quickly developing maximal casualties in the least sensitive male soldier. The "toxicity" of the chemical weapons has not changed, but our perception of "toxicity" has.

AN - 69305934; 10577848 AB - To examine the effect of single compared with repetitive (at least three) cycles of high-dose cytarabine after induction therapy for patients with acute myeloid leukemia (AML) who have the t(8;21)(q22;q22) karyotype. Patients entered onto the study had AML and t(8;21) and attained a complete remission on four successive Cancer and Leukemia Group B studies. In these studies, either > or = three cycles of high-dose cytarabine or one cycle of high-dose cytarabine was administered, followed by sequential cyclophosphamide/etoposide and mitoxantrone/diaziquone with or without filgrastim support. Outcomes of these two groups of t(8;21) patients were compared. A total of 50 patients with centrally reviewed AML and t(8;21) were assigned to receive one (n = 29) or > or = three cycles (n = 21) of high-dose cytarabine as postinduction therapy. The clinical features of these two groups of patients were similar. Initial remission duration for t(8;21) patients assigned to one cycle of high-dose cytarabine was significantly inferior (P =.03), with 62% of patients experiencing relapse with a median failure-free survival of 10.5 months, compared with the group of patients who received > or = three cycles, in which only 19% experienced relapse and failure-free survival is estimated to be greater than 35 months. Furthermore, overall survival was also significantly compromised (P =.04) in patients assigned to one cycle of high-dose cytarabine, with 59% having died as a consequence of AML, compared with 24% of those who received > or = three cycles of high-dose cytarabine. These data demonstrate that failure-free survival and overall survival of patients with t(8;21)(q22;q22) may be compromised by treatment approaches that do not include sequential high-dose cytarabine therapy.

These risks are highly uncertain. Measures to confine the dredged material and reduce these risks are likely to increase disposal costs. Risk and cost assessments for dredged material management alternatives often are associated with very large uncertainties. These uncertainties must be explicitly incorporated into risk-cost analysis to ensure that appropriate management alternatives are selected. However, considering these uncertainties may cause difficulties in decision making by making management alternatives effectively indistinguishable. A risk-cost analysis methodology that evaluates uncertainty directly in the decision framework is developed. A multi-criteria decision-making method that incorporates uncertainties using fuzzy set theory, is proposed to trade-off risks and costs (including uncertainties) so that disposal alternatives can be compared and selected.

The studied nourishments were undertaken at Ocean City, Md., Silver Strand, Calif., and Sylt, Germany, encompassing different nourishment schemes, forcing conditions, and general beach properties. Time series of measured beach topographies were used as input data in the EOF analysis, which produced maps describing the dominant spatial patterns in the data. These patterns displayed the effect of the fills, severe storms, and natural morphological features such as shore-attached shoals and rhythmic features. The evolution in time of the eigenvectors showed that the perturbation of the natural conditions typically caused by a fill disappears after about 1 year, provided that the material is available for cross-shore adjustment by the normal wave climate. If the fill material is placed high up on the beach, a series of severe storms may be needed to adjust the topography back to its natural state.

Scour occurs during times of rapid river flow and can be increased by icing conditions when sediments, including rocks, gravel, and silt, are transported by the currents, undermining bridge pier and abutment foundations and other structures. Scour is dynamic; during a single high-flow event, scour may occur during rising stages and near the peak. Deposition of sediments into the scoured area may occur during falling stages and during low flow. The worst case and the net effect cannot be easily predicted. Monitoring scour is difficult, and existing instruments have limitations that prevent their use in some situations. A technique and system employing time-domain reflectometry can be used to constantly monitor the extent of scour around riverine structures. This system is capable of continuous round-the-clock operation and can indicate changes in sediment depth of less than 5 cm.

Most engineering rock mass classifications include weathering schemes that separate the weathering profile into zones or grades that depend upon the engineering and geological properties of the rock. Many geotechnical characteristics, including weathering, are controlled by the density and arrangement of fractures within the rock, but the relationships between fracture patterns and weathering grades are typically not addressed. Fracture characteristics were investigated in 13 exposures in five study areas in weathered granite in eastern Asia. All weathering grades were present, but never in the same exposure. Two approaches were used to evaluate the field data; (1) joint spacings were tabulated and examined within each weathering grade (tabulated classification); and (2) each exposure was classified according to the dominant weathering grade (visual classification). Mean and median joint spacings and joint spacing frequency distributions were analyzed and compared statistically for each approach. The box fractal dimensions for joint spacing were calculated for exposures classified visually in each weathering grade. Three-dimensional models of fresh and weathered granite were also generated and sampled for comparison to the field data. Mean joint spacing is usually 25% or more closer in weathered granite than it is in fresh granite, and the difference between the mean spacings for weathered granite and fresh granite tend to be statistically significant. There are no significant differences between any distribution medians. The joint spacing distributions for weathered granite and fresh granite are also not statistically significantly different, and there are no significant differences among the joint spacing frequency distributions for the different grades of weathered granite. Fractal analysis of joint spacings, however, suggests spacing characteristics of fresh and slightly weathered (SW) granite are very different from those in moderately, highly, and completely weathered granite, and sampling of three-dimensional models for weathered and fresh granite supports this. In an engineering context, this suggests that joint spacing relationships in the various grades of weathered granite can be treated as the same regardless of weathering grade and that joint patterns in fresh granite must be evaluated separately. This knowledge could result in significant time and cost savings in the geotechnical characterization of these materials.

Long-term records such as those evaluated in this study show large interannual variability owing to climate fluctuations and surface irregularities which may obscure significant changes in climate. This study attempted to recognize the various contributions to the record and to assess how representative the very local record are encapsulated in the two cores studied. The two records are correlated with confidence using a time series analysis. Long-term interannual fluctuations deduced from the two cores are most likely due to spatial variations in snow accumulation on the scale of several kilometers coincident to nonuniform deposition caused by surface inequalities.

Global climate patterns including El Nino/Southern Oscillation, the Pacific Decadal Oscillation, and the North Atlantic Oscillation explained very little of the variations in flow peaks. However, large and statistically significant upward trends were found in many gauge records along the Upper Mississippi and Missouri Rivers: at Hermann on the Missouri River above the confluence with the Mississippi (p = 2 percent), at Hannibal on the Mississippi River (p < 0.1 percent), at Meredosia on the Illinois River (p = 0.7 percent), and at St. Louis on the Mississippi below the confluence of all three rivers (p = 1 percent). This challenges the traditional assumption that flood series are independent and identically distributed random variables and suggests that flood risk changes over time.

Although less effective as potable water threats, many are potentially capable of inflicting heavy casualties when ingested. Significant loss of mission capability can be anticipated even when complete recovery is possible. Properly maintained field army water purification equipment can counter this threat, but personnel responsible for the operation and maintenance of the equipment may be most at risk of exposure. Municipal water treatment facilities would be measurably less effective. Some replicating (infectious) agents and a few biotoxins are inactivated by chlorine disinfection; for others chlorine is ineffective or of unknown efficacy. This report assesses the state of our knowledge of agents as potable water threats and contemplates the consequences of intentional or collateral contamination of potable water supplies by 18 replicating agents and 9 biotoxins known or likely to be weaponized or otherwise used as threats.

We previously reported that in nerve growth factor (NGF)-differentiated PC12 cells, arachidonic acid (AA) release is associated with acetylcholine (ACh) release, botulinum neurotoxin A (BoNT/A) inhibits both processes and AA itself or a phospholipase A sub(2) (PLA sub(2)) activator can cause ACh release in BoNT/A-poisoned cells in which SNAP-25 has supposedly been hydrolyzed. In the present study, we examined the roles of two endogenous intraterminal components in neuroexocytosis: the membrane fusogenic agent AA; and the vesicle fusion protein SNAP-25. A PLA sub(2) activator, mastoparan, was used to induce the release of AA and ACh from NGF-differentiated PC12 cells. Release depended upon the mastoparan concentration, as well as Ca super(2+) influx via the neuronal-type voltage-sensitive Ca super(2+) channels. Release of ACh followed a rise in intracellular free Ca super(2+) concentration; the increased Ca super(2+) activated PLA sub(2) and, thereby, increased the AA level. Scanning and transmission electron microscopy confirmed that mastoparan-induced ACh and AA release were not due to simple diffusion through damaged plasma membranes. Treatment of PC12 cells with appropriate antisense oligonucleotides blocked SNAP-25 expression, as judged by Western blot protein analysis with a specific monoclonal antibody. Despite apparent elimination of SNAP-25, treatment of differentiated PC12 cells with mastoparan and high (80 mM) K super(+) induced ACh exocytosis. The results support the conclusion that PLA sub(2) and AA have important roles in neuroexocytosis that are independent of SNAP-25. Both PLA sub(2) and AA have been shown to be involved in actin cytoskeletal organization related to vesicle fusion and exocytosis. This mechanism may be an alternative target of BoNT/A other than SNAP-25.

We evaluated peptides that contain the QF cleavage site but are not identical in primary structure to the VAMP2 sequence surrounding the QF site for both inhibition of BoNT/B proteolytic activity and as substrates for BoNT/B. A reverse-phase high-performance liquid chromatography (RP-HPLC) method was used to measure digested peptides. A dose as high as 600 mu M of substance P, and 11-amino acid peptide containing the QF bond, was neither a substrate nor inhibitor of BoNT/B in our assay, suggesting that more than the QF bond is required to be recognized by BoNT/B. Buforin I (B-I, QF site 24-25) is 39 amino acids in length, and sequence comparison of B-I and VAMP2 indicated a similarity of 18% for conserved amino acids around the QF site. Furthermore, computer-aided secondary structure computations predict alpha -helical structures flanking the QF site for VAMP2 and for the upstream sequence of B-I. Although predictions for the downstream sequence give nearly equal tendencies for alpha -helical and beta -sheet structures, Yi et al. showed that the downstream sequence is likely to be the alpha -helix based on their examination of buforin II (B-II, a 21-amino acid subset of B-I (16-36)), which includes the QF site and the downstream sequence of B-I. Buforin I was found not to be a substrate for BoNT/B; however, B-I dose dependently and competitively inhibited BoNT/B activity, yielding IC sub(50) = 1 x 10 super(- 6) M. In contrast, B-II was not a substrate for BoNT/B and exhibited only 25% of the B-I inhibition of BoNT/B. Two additional B-I deletion peptides were tested for inhibition of BoNT/B proteolysis: peptide 36 (36 mer; containing B-I amino acids 1-36) and peptide 24 (24 mer; B-I amino acids 16-39). Peptide 24 had a similar inhibitory effect to B-II (ca. 25% of B-I) but peptide 36 was almost 50% as potent as B-I. These findings suggest that the buforin tertiary structure is important for the inhibitory activity of these peptides for BoNT/B.

The effects of inundation pattern and wrack deposition have been studied independently but not in combination. We manipulated inundation of tidal creek water and wrack presence individually and in combination, in two neighboring communities within a Virginia high salt marsh during 1994 and 1995. The effects of these manipulations were assessed by measurements of aboveground plant biomass. Altered inundation by itself produced little response in the various categories of plant biomass measured. Wrack deposition affected all species (i.e., Juncus roemerianus, Spartina patens, and Distichlis spicata) showing a significant reduction in aboveground biomass, as expected. Recovery after wrack deposition was dependent on the species. S. patens and D. spicata recovered from wrack deposition within one growing season, while J. roemerianus did not. Because the effects of wrack deposition greatly exceeded those of experimentally increased inundation, the possible interactions between the two were masked. Increased inundation may have inhibited the colonization of bare areas by some species after the removal of wrack from an area, although statistical significance at alpha = 0.01 was not reached. Our results confirm that wrack deposition can cause the redistribution of species within the high marsh community. Altered inundation may have a greater effect on the re-establishment of the plant community after wrack deposition than it does without wrack deposition.

The amount of light reduction due to dock shading was measured using quantum spherical irradiance meters. Seagrasses were present under docks; they were shaded such that light levels were 19% and 16% of surface irradiance, at shallow and deep sites, responsively. Shoot density was 40-47% lower in shaded plots than in unshaded plots; total biomass was 30-33% lower in shaded plots than in unshaded plots. In contrast, blade length and chlorophyll content were increased at shaded plots relative to unshaded plots. Seagrasses were not found under docks at light levels less than 14% of surface irradiance. These results are in agreement with published in situ compensation irradiance estimates of 15-18% for Halodule wrightii in Texas coastal waters. Shading effects were most apparent between the hours of 1000 and 1500; therefore, the light received during the early morning and late afternoon hours may be critical for plants growing under docks. The north-south orientation of the docks in this study is likely an important factor contributing to the continued survival and growth of the seagrasses.

In this study, we have used mixed cultures of human peripheral blood monocytes and lymphocytes to investigate biochemical events controlling SEB induction of TNF- alpha . TNF- alpha production induced by SEB in mixed cultures is more closely associated with T cells than with monocytes: (i) a TCR-binding-site mutant of SEB (N23F) is less active in TNF- alpha induction than an MHC class II receptor-binding-site mutant (F44R), and (ii) flow cytometric analysis indicated that SEB induced TNF- alpha production in T cells but not in monocytes. Pretreatment of cells with inhibitors of signal transduction pathways was employed to further define events in SEB-induced TNF- alpha production. Neither protein kinase A inhibitors nor two protein tyrosine kinase inhibitors altered SEB-induced TNF- alpha production. In contrast, SEB induced protein kinase C (PKC) translocation, and pretreatment of cultures with inhibitors of PKC blocked TNF- alpha induction. Alteration of levels of diacylglycerol (DAG), an activator of PKC, by treatment with inhibitors of phospholipase C or DAG kinase also altered SEB-induced TNF- alpha production. These data suggest that PKC activation plays a critical role in SEB-induced TNF- alpha production in human T cells.

An experimental study was performed to select it. The experiments consisted of two parts, Part 1 tests were conducted according to an accepted engineering standard to compare four candidate geotextiles. Part 2 tests simulated expected field conditions, and were conducted to determine whether one geotextile selected from the Part 1 tests was likely to perform well. The geotextile selected for Part 2 tests retained particles of 0.1 mm and larger, and was installed as a silt fence filter in the field. The silt fence filter was removed shortly after dredging began because it clogged, primarily due to unexpected, high amounts of suspended sediment in the supernatant. The design of the support structure for the silt fence did not permit maintenance of the filter, which may have prevented its failure. The failure may also have been prevented if salt or other materials used to promote flocculation of the dredged spoils were readily available and used on the spoils. The selection procedure described may be helpful because the conditions tested for in the laboratory are likely to occur or could be induced.

AN - 69236191; 10547433 AB - A purified monovalent botulinum type F toxoid vaccine was administered to 35 healthy adult volunteers in a phase I clinical trial. Serum samples from the vaccinated volunteers were evaluated for an antibody response at various time intervals over 1 year by mouse bioassay and ELISA. The antibody response was measured for varying doses of vaccine (2, 5, or 10 microg), and after single or multiple (two or three doses @ 10 microg) vaccinations. Six out of 15 (40%) individuals developed antibody titers after receiving a single dose. After two and three vaccinations, there was a 90% (18/20) and 100% (10/10) seroconversion rate, respectively. Eight months after initial injection, 57 and 63% of individuals were antibody positive following two or three vaccinations, respectively. Single vaccinations, at any of the tested dosages, elicited lower, if any, antibody response than did multiple vaccinations. After the third vaccination, ELISA titers positively correlated with mouse neutralization bioassay titers (r(2)=0.86).

Volunteers (n = 12) were male infantry soldiers who were experienced marksmen. Volunteers shot while wearing three equipment configurations: the Battle Dress Uniform (BDU), BDU and the conventional fighting load (CONV), and BDU and the LW fighting load (LWFL). Significant differences (p < 0.05) in distance from center of mass (DCM), shot group tightness (SGT) and percent of targets hit between equipment conditions were seen. Shooters shot approximately 42% farther away from the target center, had shot groups approximately 214% more disperse, and took 38% longer when shooting prone with the LWFL compared to the CONV conditions. The principal cause of shooting impairment while shooting prone with LWFL was the contact between the hard pack and the helmet preventing the shooter from properly lifting his head to see the target. Generally, when designing equipment, engineers should take into account performance under all body positions likely to be encountered in military operations. These results have demonstrated that both the standing and prone positions for shooting need to be considered when designing combat equipment for the fighting soldier.

The plan's objectives are reasonable and well-stated, but the criteria incorporated within the objectives may be unsuitable for monitoring some Gulf sturgeon populations. We propose the following revisions based on a 5-year study of Gulf sturgeon in the Pearl River system of Mississippi and Louisiana: (1) set specific statistical criteria for detecting population changes with emphasis on defining sufficient sampling effort to minimize type II errors; (2) use simple population models incorporating estimates of population size, mortality, and recruitment to ascertain population trends and define recovery; and (3) define a minimum number of adults within a self-sustaining population (in this case 100). These revisions, while perhaps not universally applicable, are probably appropriate in systems with many outlets, such as the Pearl River, where Gulf sturgeon are most easily sampled in summertime habitats.

Resource managers of the installations need wetland inventories to improve stewardship of these lands. Digital geographic data are readily available to land managers. The use of these data to inventory wetlands has not been demonstrated. As part of a project to integrate wetlands into the ITAM (Integrated Training Area Management) program for managing Army lands, wetland inventory methods using existing digital geographic information for two terrains on Army installations in Alaska were explored: (1) glacial moraine depressions and estuarine marsh on Fort Richardson, and (2) discontinuous permafrost and taiga forest on Fort Wainwright's Yukon Command training site. Our results show that (1) existing geographic data used to infer wetland locations (Landsat Thematic Mapper [TM], National Wetland Inventory [NWI] maps, and hydric soil maps) only partly agree, and (2) optimum Landsat TM band combinations for wetland inventory vary on a site-specific basis. Landsat TM classifications (unsupervised) of Fort Richardson wetlands compared reasonably well (0.73 Kappa Index of Agreement [KIA] with the NWI map as long as the band combinations included at least one visible and the near-infrared wavelength band (e.g., bands 3, 4, and 5 or bands 2, 3, and 4). The Fort Richardson hydric soils map indicates more extensive wetlands than indicated by the NWI (0.64 KIA). The Landsat TM classification could be made to agree fairly well with the NWI map (0.73 KIA). At Fort Wainwright, use of the thermal wavelength band (6, 4, and 2 composite) improved Landsat TM classification agreement with the NWI (0.67 KIA) because of warmer apparent brightness temperatures of lowland wetland sites compared to upland forested sites. Topographic position in the taiga forest plays a strong role in determining soil moisture, dominant vegetation, and whether or not the site is underlain by permafrost; therefore, a wet terrain map derived from a digital elevation model agreed nearly as well to the NWI map (0.64 KIA) as did the Landsat TM classification (0.67 KIA). Existing geographic information can serve as an initial wetland map. However, accurate wetland maps will require field mapping. JF - Special Report - Corps of Engineers, U. S.

The purpose of this study was to modify the WHO test procedure to make the holding period of lice shorter and the handling of lice easier. Susceptible lice from a laboratory colony were placed in a petri dish containing a paper that had been treated with an insecticide solution. After 6 h, the petri dish was turned on its side and lightly tapped on the table. Lice that were unable to cling to the paper were counted as knocked down. The KD50 in mg (AI)/ml of the insecticide solution used to treat the papers was as follows: lindane 0.060, permethrin 0.115, d-phenothrin 0.554, and malathion 1.008. If the diagnostic dose is set at 2 times the KD99, for this test procedure the diagnostic doses and WHO equivalent dose would be lindane, 0.368 mg (AI)/ml (WHO 0.132%); permethrin, 0.498 mg (AI)/ml (WHO 0.206%); d-phenothrin, 2.680 mg (AI)/ml (WHO 1.107%); and malathion, 5.212 mg (AI)/ml (WHO 2.020%).

AN - 69298177; 10573883 AB - Airbag deployment includes very intense acoustic stimulation, yet almost no tests of auditory hazard have been done with real ears. Therefore 32 anesthetized cats, positioned at the driver and passenger locations in a pickup truck, were exposed in pairs to one airbag deployment (electrically initiated). Hearing was tested at 1, 2, 4, 8, and 16 kHz by evoked-response audiometry just before exposure, immediately after and at 1 month and 6 months. Exposure conditions included doors open, compartment closed, and closed compartment sealed with tape: seven exposures to passenger bag only and nine to driver and passenger bags. Peak pressures ranged from 167 to 173 dB with unweighted energies as high as 4000 J/m2 (or 8 hr LEQA = 95.5 dB). The immediate threshold shift averaged 60 dB at 4.0 kHz that resolved to an average permanent shift of 37 dB.

AN - 69208706; 10531238 AB - Both native and mutant forms of cholera toxin (CT) and heat-labile enterotoxin (LT) are effective adjuvants for antigens and killed whole-cell preparations. To determine whether these toxin molecules could also boost the immunogenicity and efficacy of live attenuated vaccines directed against shigellosis, the guinea pig keratoconjunctivitis model was used to evaluate the adjuvant effect of these toxin molecules on EcSf2a-3, a DeltavirG DeltaaroD Escherichia coli-Shigella flexneri 2a hybrid vaccine strain that was previously found to be less protective than its parent strain in the guinea pig model. Experiments using native and mutant toxin molecules showed that both CT and LT and mutant derivatives were effective as an adjuvant for EcSf2a-3 and that the mutant toxin molecules, which were developed to retain adjuvanticity without the toxicity associated with the native molecules, were as effective as the native toxin molecules as adjuvants. Protective efficacy was enhanced for both the oral and intranasal routes of immunization. Serum antibody response to the S. flexneri 2a O antigen, the primary antigen for protective immunity, was not dependent on the addition of an adjuvant. However, enumeration of the O-antigen-specific immunoglobulin G (IgG) and IgA antibody-secreting cells in the spleen and draining lymph nodes following intranasal immunization suggested that enhancement of the local immune response by the toxin molecules may contribute to the observed increase in protective efficacy. The efficacy of heat-killed S. flexneri 2a was enhanced only by mutant LT molecules. These results suggest that the best candidates for enhancing the efficacy of both live attenuated and heat-killed Shigella vaccines with minimal reactogenicity are the mutant toxin molecules.

In order for this to occur a hydrological cycle would be necessary in which the chemical weathering of silicate rocks consumes CO (sub 2) that precipitates as carbonates in a martian ocean which probably had a very high alkalinity. The consumption of atmospheric CO (sub 2) by this process would result in a gradual decrease of the atmospheric greenhouse influence and lead to a cooler climate. Once the Mars surface became cool enough for freezing conditions to prevail, the hydrological cycle would largely cease, and the uptake of CO (sub 2) by silicate rock weathering would greatly diminish. The alkalinity of the freezing sea-water would probably be enough for the removal of all Ca as CaCO (sub 3) ; some Mg and Na would also probably be removed. The removal of these cations as carbonates would have a major influence on the final T at which liquid brines would be able to persist. During the period of freezing, the oceans would act as a source for CO (sub 2) rather than a sink, further slowing the rate of climate change on Mars.

In an atmosphere this advancing curtain acts like a semipermeable barrier that displaces the surrounding gas. The generated flow separates near the top of the curtain to form a vortex ring whose strong winds entrain, transport, and deposit fine-grained ejecta, affecting the morphology of distal ejecta deposited on planets with atmospheres. We have investigated how the curtain width and velocity, particle concentration, size distribution and velocity parallel to the curtain, and the density, viscosity, and compressibility of the surrounding atmosphere controls the flow strength of these winds. Wind tunnel tests (Part 1 [Barnouin-Jha et al., this issue]) show that for an ejecta-like porous plate, the hydraulic resistance, a measure of energy losses for one-dimensional porous flow, governs the position along the curtain where it becomes effectively impermeable. Combined with suitable cratering models and published hydraulic resistance data, this information allows estimating the flow strength or circulation generated by an advancing curtain. The present study assesses the influence of atmospheric compressibility and particle motion parallel to the curtain surface on the curtain's circulation in order to improve these estimates. Numerical experiments indicate that atmospheric compressibility has little effect on the circulation at Mach number below 0.5, consistent with analytical solutions. Analytical solutions show, however, that this flow circulation should increase significantly at higher Mach numbers. The numerical experiments also show that individual ejecta traveling parallel to the surface of the curtain enhance the induced circulation by 9% to 33%.

The outward advancing motion of this curtain displaces atmosphere to generate a ring vortex whose winds can entrain, transport, and deposit ejecta and fine-grained surface materials. Curtain width and velocity, particle concentration, size distribution and motion parallel to the curtain, and the density, viscosity, and compressibility of the surrounding atmosphere all influence the vortex circulation strength. As analogs to an advancing ejecta curtain, we tested the effect of inclined solid and porous plates on vortex formation in a low-speed wind tunnel. We found that hydraulic resistance, a measure of energy losses for 1-D porous flow, governs the position along a porous plate where it becomes effectively permeable and flow separation occurs. The resulting flow field is similar to that over an inclined solid plate of the same effective length. Energy losses through the top, permeable portions of the plate reduce circulation strength by only 7% relative to flow over a solid plate. The two parameters needed to estimate circulation strength, curtain velocity and impermeable height, can thus be determined by coupling an impact model with published hydraulic resistance data. These tests also served to calibrate a numerical model, which we then applied to investigate the influence of atmospheric compressibility and particle motion parallel to the curtain (see Part 2 [Barnouin-Jha et al., this issue]). These two studies provide a method to predict the curtain-induced flow and consequent patterns of debris deposition associated with impacts on planets with atmospheres.

The chemicals studied were limited to those that are readily available most anywhere, but that are not marketed as admixtures for concrete. Four admixtures were developed from these chemicals that allowed mortar to gain full strength at -10 degrees C as rapidly as normal mortar cured at temperatures between 5 and 10 degrees C. A host of other chemicals allowed mortar to recover full strength when cooled to the point that cement hydration ceased or that allowed mortar to continually gain modest strength while at low temperature with only minimal loss of ultimate strength. Guidance is provided for expedient field use--for concrete not expected to last more than 5 years. JF - Special Report - Corps of Engineers, U. S.

Here, 19 adult nine-banded armadillos were inoculated intradermally with M. ulcerans. Injection sites were examined and skin samples obtained for histologic and microbiology studies. Necropsies were conducted to assess systemic involvement. In group 1 (n = 4), 2 animals developed progressive skin ulcers with undermined borders at the injection sites within 6-10 weeks. Biopsies showed features similar to human disease including extensive necrosis in the deep dermis and subcutaneous fat, mixed cellular infiltrates, and acid-fast bacilli (AFB). In group 2 (n = 15), 5 animals developed progressive skin ulcers, 3 had evanescent papulo-nodules, 3 died shortly after inoculation of unknown causes, and 4 showed no signs of infection. Lesion samples from 3 animals with progressive ulcers were culture positive for AFB. Our findings indicate that nine-banded armadillos are susceptible to M. ulcerans and may develop cutaneous lesions that closely mimic Buruli ulcer.

Hydroacoustic counts of guided fish were significantly correlated with concurrent gatewell catches (r super(2) = 0.73; N = 39), as were hydroacoustic counts of unguided fish with fyke-net catches (r super(2) = 0.71; N = 39). However, hydroacoustic sampling significantly underestimated both guided and unguided fish passage relative to netting estimates. We could not explain the underestimates by modeling hydroacoustic detectability, and the distribution of fish passage across the intake width was not skewed away from transducer sampling volumes. Hydroacoustics provided relatively unbiased estimates of fish guidance efficiency (guided/[guided + unguided]) because of compensating errors in the numerator and denominator. The best correlation between net and hydroacoustic estimates of efficiency (r super(2) = 0.85; N = 40) had a slope of 0.91 when the intercept was set to zero. Precision of hydroacoustic estimates increased 50% and the r super(2) of the correlation line increased 19% when hydroacoustic sampling duration was extended from the typical netting duration of 1-2 h to 4 h. Further increases in hydroacoustic sampling duration from 5 to 9 h provided no significant improvement in correlations. Strong correlations between estimates of FGE derived from netting and hydroacoustic sampling are reassuring and useful because both methods have advantages that can be exploited to improve overall sampling effectiveness at a hydropower project. The derivation of a universally applicable relation between hydroacoustic and physical-capture estimates of fish passage is not possible given many potential deployment-dependent biases in estimates.

A vaccine to protect humans from occupational exposure or from zoonotic infection in areas where the disease is endemic would reduce an important cause of morbidity worldwide. Vaccines currently used in animals are unsuitable for human use. We tested a live, attenuated, purine-auxotrophic mutant strain of Brucella melitensis, WR201, for its ability to elicit cellular and humoral immune responses and to protect mice against intranasal challenge with B. melitensis 16M. Mice inoculated intraperitoneally with WR201 made serum antibody to lipopolysaccharide and non-O-polysaccharide antigens. Splenocytes from immunized animals released interleukin-2 (IL-2), gamma interferon, and IL-10 when cultured with Brucella antigens. Immunization led to protection from disseminated infection but had only a slight effect on clearance of the challenge inoculum from the lungs. These studies suggest that WR201 should be further investigated as a vaccine to prevent human brucellosis.

The medium (M) and small (S) gene segments of SEOV encode the viral envelope glycoproteins and nucleocapsid protein, respectively. We compared the immunogenicity and protective efficacy of naked DNA (pWRG7077), DNA-based Sindbis replicon (pSIN2.5), and packaged Sindbis replicon vectors (pSINrep5), containing either the M or S gene segment of SEOV in Syrian hamsters. All of the vectors elicited an anti-SEOV immune response to the expressed SEOV gene products. Vaccinated hamsters were challenged with SEOV and monitored for evidence of infection. Protection from infection was strongly associated with M-gene vaccination. A small number of S-gene-vaccinated animals also were protected. Hamsters vaccinated with the pWRG7077 vector expressing the M gene demonstrated the most consistent protection from SEOV infection and also were protected from heterologous hantavirus (Hantaan virus) infection.

We previously demonstrated that gene gun inoculation of mice with naked DNA vaccines expressing the prM and E genes of these viruses resulted in long-lived homologous and heterologous protective immunity (Schmaljohn et al., 1997). To further evaluate these vaccines, we inoculated rhesus macaques by gene gun with the RSSEV or CEEV vaccines or with both DNA vaccines and compared resulting antibody titers with those obtained by vaccination with a commercial, formalin-inactivated vaccine administered at the human dose. Vaccinations were given at days 0, 30, and 70. All of the vaccines elicited antibodies detected by ELISA and by plaque-reduction neutralization tests. The neutralizing antibody responses persisted for at least 15 weeks after the final vaccination. Because monkeys are not uniformly susceptible to tick-borne encephalitis, the protective properties of the vaccines were assessed by passive transfer of monkey sera to mice and subsequent challenge of the mice with RSSEV or CEEV. One hour after transfer, mice that received 50 mu l of sera from monkeys vaccinated with both DNA vaccines had circulating neutralizing antibody levels <20-80. All of these mice were protected from challenge with RSSEV or CEEV. Mice that received 10 mu l of sera from monkeys vaccinated with the individual DNA vaccines, both DNA vaccines, or a commercial vaccine were partially to completely protected from RSSEV or CEEV challenge. These data suggest that DNA vaccines may offer protective immunity to primates similar to that obtained with a commercial inactivated-virus vaccine.

AN - 85404774; pmid-10522931 AB - OBJECTIVES: Review the clinical signs and symptoms, management, bacteriology and outcomes of patients treated for lateral sinus thrombosis. STUDY DESIGN: A retrospective review of six patients, treated from 1993 through 1998, with an intraoperatively confirmed diagnosis of lateral sinus thrombosis. METHODS: All charts from 1993 through 1998 coded for sinus thrombosis, meningitis, brain abscess, otitic hydrocephalus, subdural abscess, and mastoidectomy were reviewed. Operative reports, radiological examinations, laboratory data, culture data and other pertinent data were reviewed. RESULTS: The presenting symptoms ranged from headache to mental status changes. All patients had a history of chronic ear disease and all had at least one additional intracranial complication. The range of additional intracranial complications included otitic hydrocephalus, epidural abscess, and brain abscess. All of the infections were polymicrobial, with a predominance of anaerobes. There were no mortalities; morbidities included anacusis, acute respiratory distress syndrome, reoperation, seizures, septic cardiomyopathy, transfusion, ventriculoperitoneal shunt and nutritional supplementation. CONCLUSION: In patients with otologic disease, complaints of headache, earache or photophobia should warrant an evaluation. The presence of lateral sinus thrombosis mandates further investigation for additional intracranial complications. Conservative surgical intervention, consisting of removal of all perisinus infection and needle aspiration of the sinus, has been found to be effective. Lateral sinus thrombosis is an uncommon complication of otitis media, with potentially significant morbidities, necessitating a high index of suspicion.

U.S. ARMY Research Institute of Environmental Medicine. AN - 70824420; 10519479 AB - This study was a cross validation of three heat strain prediction models developed at the U.S. Army Research Institute of Environmental Medicine: the ARIEM, HSDA, and ARIEM-EXP models ability to predict core temperature. Seven heat-acclimated subjects completed twelve experimental tests, six in each of two hot climates, at three exercise intensities and two uniform configurations in each climate. Experimental results showed physiological responses as expected with heat strain increasing with work load and level of protective clothing, but with similar heat strain between the two environments matched for wet bulb, globe index. Neither the ARIEM or HSDA model closely predicted core temperatures over the course of the experiment, due mostly to an abrupt initial rise in core temperature in both models. A proportionality constant in the ARIEM-EXP buffered some of this abrupt rise. Comparisons of the core temperature and tolerance times data with the three models led to the conclusions that for healthy males: 1) the ARIEM and HSDA models provide conservative safety limits as a result of predicting rapid initial increases in core temperature; 2) the ARIEM-EXP most closely represents core temperature responses; 3) the ARIEM-EXP requires modifications with an alternate proportionality coefficient to increase accuracy for low metabolic cost exercise; 4) all of the models require additional input from existing research on tolerance to heat strain to better predict tolerance times; and 5) additional models should be examined to investigate the transient state of the body as it is affected by environment, clothing and exercise.

AN - 70057938; 10495308 AB - Potential action of ultra-wideband (UWB) electromagnetic field pulses on effects of N(G)-nitro- L-arginine methyl ester (L-NAME), an inhibitor of nitric oxide synthase (NOS), on nociception and locomotor activity was investigated in CF-1 mice. Animals were injected IP with saline or 50 mg/kg L-NAME and exposed for 30 min to no pulses (sham exposure) or UWB pulses with electric field parameters of 102+/-1 kV/m peak amplitude, 0.90+/-0.05 ns duration, and 160+/-5 ps rise time (mean+/-S.D.) at 600/s. Animals were tested for thermal nociceptive responses on a 50 degrees C surface and for spontaneous locomotor activity for 5 min. L-NAME by itself increased mean first-response (paw lift, shake, or lick; jump) and back-paw-lick response latencies and mean locomotor activity. Exposure to UWB pulses reduced the L-NAME-induced increase in back-paw-lick latency by 22%, but this change was not statistically significant. The L-NAME-induced hyperactivity was not present after UWB exposure. Reduction and cancellation of effects of L-NAME suggest activation of opposing mechanism(s) by the UWB pulses, possibly including increase of nitric oxide production by NOS. The action, or actions, of UWB pulses appears to be more effective on locomotor activity than on thermal nociception in CF-1 mice.

AN - 70040948; 10490930 AB - AHN649, an analog of dextromethorphan (DM) and a relatively selective low-affinity N-methyl-D-aspartate antagonist, was evaluated for neuroprotective effects using the rat intraluminal filament model of temporary middle cerebral artery occlusion. Rats were subjected to 2 h of focal ischemia followed by 72 h of reperfusion. In vehicle-treated rats, middle cerebral artery occlusion resulted in neurological deficits and severe infarction measuring 232 +/- 25 mm(3), representing approximately 25% contralateral hemispheric infarction. Post-treatment with AHN649 (0.156-20 mg/kg i.v.) or DM (0.156-10 mg/kg i.v.) significantly reduced cortical infarct volume by 40 to 60% compared with vehicle-control treatments. AHN649 neuroprotection was linear and dose dependent (ED(50) = 0.80 mg/kg), whereas DM neuroprotection (ED(50) = 1.25 mg/kg) was nonlinear and less effective at the higher doses (2.5-10 mg/kg). Although impaired neurological function scores improved in all groups by 24 to 72 h, the most dramatic improvement was associated with AHN649 treatments. In a rat electroencephalographic model of brain function, separate neurotoxicity experiments revealed that acute i.v. doses of DM caused seizures (ED(50) = 19 mg/kg) and death (LD(50) = 27 mg/kg). In contrast, AHN649 failed to induce seizure activity at doses up to 100 mg/kg (LD(50) = 79 mg/kg). Collectively, AHN649 is described as a potent, efficacious neuroprotective agent devoid of serious central nervous system neurotoxicity and possessing potential therapeutic value as antistroke treatment. Furthermore, the feasibility of targeting low-affinity N-methyl-D-aspartate-site ligands as postinjury therapy for ischemic brain injury has been confirmed.

AN - 70014471; 10479174 AB - The exotoxins produced by Staphylococcus aureus, staphylococcal enterotoxins (SE) A-E and toxic shock syndrome toxin (TSST)-1, which are associated with serious diseases, including food poisoning and toxic shock syndrome, are termed superantigens (SAgs). To examine whether common antigenic epitopes were present and whether vaccination with 1 bacterial SAg could protect against challenge with a different SE or TSST-1, mice were vaccinated with SEA, SEB, SEC1, or TSST-1 individually or in combination. Mice injected with a single toxin developed high antibody titers against other SAgs. Marked improvement in survival was observed when immunized mice were challenged with a heterologous toxin. Mice vaccinated with a mixture of toxins were fully protected against 1 or multiple toxin challenges, indicating no interference effects of multivalent vaccinations. More importantly, higher titers were found against each SAg with the multivalent vaccination than with injection with a single SAg. Thus, immunizations with 1 SAg can induce cross-protective antibodies to heterologous SAgs, and multicomponent vaccination can enhance antibody responses against each bacterial SAg.

This study examined age, gender, ethnicity, self-esteem, physical activity, parental smoking, and socioeconomic status as predictors of smokeless tobacco use among middle school children. Subjects included 1,211 youth (White (64%), Black (24%), Hispanic (6%), and Other (6%); age 12.2) participating in the Cardiovascular Health in Children and Youth (CHIC II) study. All data were collected by questionnaire. Factors related to ever using smokeless tobacco included older age (p < .001), being male (p < .001), lower self-esteem (p < .001), and having parents who currently (p = .02) or formerly (p = .05) smoked. Hispanics reported a higher current usage rate than other ethnic groups (p < .001). White youth in the lowest socioeconomic status were most likely to be experimental users (p = .007), while those in the high socioeconomic status were more likely to be current users (p = .006).

This article summarizes efforts in Florida to protect, preserve, and restore the state's sandy shores. A brief history of the Federal and state shore protection programs is presented, followed by a review of the state of Florida's efforts in beach and shore management. In particular, the state's 1998 legislation creating dedicated funding source for beach restoration and nourishment is discussed. State guidelines, criteria, and procedures for participation in a comprehensive, long-term statewide beach management plan for erosion control are reviewed. The emphasis of Florida's current law and policy is to coordinate beach nourishment state-wide, with emphasis on regional approaches to beach restoration and nourishment. Beach restoration and nourishment projects are to be funded in a manner that encourages cost-saving strategies, fosters regional coordination of projects, improves the performance of projects, and provides long-term solutions.

The case study is presented to highlight the value and application of a conceptual integration of economic, salmonid population, physical habitat, and water allocation models. Five alternative regimes, all intended to increase low winter flows, were investigated. Habitat enhancements created by alternative regimes were translated to population responses and economic benefits. Analysis concluded that instream flows cannot compete on the northern Colorado water rental market; cooperative agreements offer an economically feasible way to enhance instream flows; and establishing an instream flow program on the Cache la Poudre River mainstem is a potentially profitable opportunity. The alliance of models is a dynamic multidisciplinary tool for use in professional settings and offers valuable insight for decision-making processes involved in water management.

ER - TY - JOUR T1 - Comparison of hematologic consequences and efficacy of p-aminophenones in mice AN - 17449396; 4663888 AB - Controlled methemoglobin (MHb) formation is one strategy employed to counter cyanide (CN) toxicity. Currently available MHb formers present certain drawbacks and limitations. The purpose of this study was to characterize, in mice, the hematologic effects of the MHb-forming compound p-aminopropiophenone (PAPP), and two structurally-related p-aminophenones, p-aminoheptanoylphenone (PAHP) and p-aminooctanoylphenone (PAOP). Although these three p-aminophenones have been shown previously to be efficacious as pretreatments against CN, a more complete understanding of their hematologic effects is lacking. In addition, because the active form of PAPP has been shown to be its N-hydroxy metabolite, the N-hydroxy metabolites of PAPP, PAHP and PAOP were also tested. Using a hemoximeter, blood samples obtained -2 to +180 min relative to intramuscular (i.m.) or intraperitoneal (i.p.) drug injections were evaluated. Sodium nitrite (NaNO sub(2)) and the appropriate solvents served as the positive and negative controls, respectively. Dose-, time-, route-, and compound-related effects were observed. MHb and sulfhemoglobin levels increased, whereas levels of those parameters related to oxygen-carrying capacity of the blood, such as, oxygen saturation and oxyhemoglobin decreased. In general, the effects of PAHP and PAOP were longer lasting than those of PAPP and NaNO sub(2). Furthermore, PAPP and NaNO sub(2) were equally effective with either route of administration. Conversely, PAHP and PAOP showed larger effects when administered i.p. versus i.m. The animals treated with N-hydroxy metabolities of the p-aminophenones also showed similar changes in the hematological parameters measured. N-hydroxy PAPP was shown to be the most rapidly acting MHb-forming compound examined in this series. It could achieve therapeutic concentrations of MHb within 2 min and thus may be considered as a treatment for CN intoxication. Although additional work is needed, these data provide information that will be useful for the successful development of improved anti-CN MHb formers.

After rats were trained on the ADT, AE (25, 75, 125 mg/kg, IM) or vehicle (sesame oil) was administered and behavioral performance was evaluated for 11 consecutive days. Histological evaluation of the brains was performed using thionine and cupric-silver staining. Damaged cells were counted in specific brainstem nuclei of all rats and a qualitative analysis of the rostral-caudal extent of selected brains was performed. Behavioral performance was not significantly affected by any treatment although some evidence of disruption was observed, particularly after the largest dose. At 125 mg/kg, AE produced statistically significant neuropathology, including chromatolysis, in the nucleus trapezoideus and nucleus superior olive. AE at 75 mg/kg, produced significant neuropathology in the nucleus trapezoideus. Neither AE at 25 mg/kg, nor vehicle produced damage. Qualitative analysis revealed a pattern of neuropathology focused in the brainstem. The results show that, in rats, a single dose of AE can produce a pattern of brainstem neuropathology and that specific brainstem nuclei, including auditory nuclei, are particularly vulnerable. These results are consistent with, and extend, previous studies demonstrating brainstem neurotoxicity from repeated AE administration. Moreover, early detection of AE-induced neuropathology is problematic and may require selective examination of brainstem functions.

A major advantage of the species is that there is no need to maintain a continuous culture to have organisms immediately available for testing. Rather, the embryos arc viable under long-term storage conditions and can be hatched within a few hours. The tests require only 24 h with standard laboratory equipment. Sensitivity levels for 11 representative toxicants were comparable to those reported for five of the standard U.S. Environmental Protection Agency test species requiring continuous culture.

AN - 70043807; 10495009 AB - The ability of five organophosphorus nerve agents (tabun, sarin, soman, GF, and VX) to produce brain seizures and the effectiveness of atropine as an anticonvulsant treatment against these nerve agents were studied in two different animal models--the rat and guinea pig. All animals were implanted with cortical electrodes for EEG recordings. Five minutes after the start of nerve agent-induced EEG seizures, animals were treated intramuscularly (IM) with different doses of atropine sulfate and observed for seizure termination. The anticonvulsant ED50 of atropine sulfate for termination of seizures induced by each nerve agent was calculated and compared. In the rat model, selected oximes were administered either before, concurrent with, or following challenge with a 1.6 x LD50 dose of a given nerve agent to maximize seizure development with certain agent/oxime combinations. The choice and the timing of oxime administration significantly effected the incidence of seizure development by different nerve agents. When oxime administration did not effect seizure development (tabun, soman) the anticonvulsant ED50 for atropine sulfate was the same, regardless of the nerve agent used to elicit the seizure. When oxime administration reduced the incidence of seizure occurrence (sarin, GF, VX), the anticonvulsant ED50 dose of atropine sulfate for a nerve agent was lower. In the guinea pig model, animals were pretreated with pyridostigmine prior to challenge with 2 x LD50 of a given agent, and treated 1 min later with atropine sulfate (2 mg/kg) and 2-PAM (25 mg/kg). Under these conditions, the incidence, latency of seizure development, and anticonvulsant ED50s of atropine for soman-, tabun-, and GF-elicited seizures were virtually identical. With sarin, although the latency of seizure development was the same as with soman, tabun, and GF, seizures occurred with a lower incidence, and the anticonvulsant ED50 of atropine was lower. With VX, the latency of seizure development was notably longer, while the incidence of seizure development and anticonvulsant ED50 of atropine were significantly lower than with soman, tabun, or GF. In both models, a lower incidence of seizure development predicted a lower anticonvulsant dose of atropine. In the rat, the incidence of seizure development and the anticonvulsant effectiveness of atropine was highly dependent on the oxime used. In the guinea pig, higher doses of atropine sulfate were required to control soman-, tabun-, or GF-induced seizures, perhaps reflecting the lower cholinesterase reactivating ability of 2-PAM against these agents.

AN - 70019428; 10477446 AB - Phosgene-induced pulmonary edema formation has been under investigation for many years. One mechanism of protection may involve the use of antioxidants. Previously, it has been shown that butylated hydroxyanisole (BHA) treatment can enhance glutathione (GSH) levels. The present study focused on dietary supplementation in mice using BHA, a phenolic compound used in food preservation. Three groups of male CD-1 mice were studied: group 1, control animals fed with Purina rodent chow 5002; group 2, fed 0.75% BHA (w/w) in 5002; and group 3, fed 1.5% BHA (w/w) in 5002. Mice were fed for 22 days. On day 23 mice were exposed to 32 mg/m(3) phosgene for 20 min in a whole-body exposure chamber. Survival rate (SR) and odds ratio (OR) were determined at 12 and 24 h. In mice that died within 12 h, the lungs were removed immediately and lung wet weights (WW), dry weights (DW), lung wet weight/body weight ratio (LWW/BW), and lung tissue total glutathione (GSH) were assessed. For 12-h data, 6 mice from the 1.5% BHA group were sacrificed for lung tissue measurements. The SR for 0.75% BHA was 80% at 12 h and 55% at 24 h, compared with 36% and 23%, respectively, for controls. For 1.5% BHA, the 12- and 24-h SR were 100% and 92%, respectively. Odds ratios of 6.9 for 0.75% BHA and 46.6 for 1.5% BHA at 12 h and 4.0 and 42 for 0. 75% and 1.5% BHA, respectively, at 24 h were significantly (chi2) higher than control diet phosgene-exposed mice. Dietary pretreatment with 0.75% and 1.5% BHA significantly enhanced lung tissue GSH, 1.8-fold (p < or =.01) and 5.8-fold (p < or =.01), respectively, compared with phosgene-exposed control diet. Both BHA-supplemented diets significantly reduced WW. Only 1.5% BHA reduced DW, a measure of lung hyperaggregation. and LWW/BW compared with control diet. In air-exposed controls, BHA induced a dose-responsive decrease in WW, DW, LWW/BW ratio, and GSH. In conclusion, dietary pretreatment with BHA at the two dose levels reduced lung edema and lethality by enhancing lung tissue GSH in mice exposed to phosgene.

Virus infection and dissemination rates were significantly higher in Cx. taeniopus orally exposed to IE as compared to those orally exposed to IAB virus. In contrast, both infection and dissemination rates were similar in Cx. ocossa exposed to either IAB or IE strains of VEE virus. Thus, susceptibility to epizootic and enzootic strains of VEE virus seems to be species specific within the subgenus Culex (Melanoconion). Both species transmitted each strain of VEE virus after intrathoracic inoculation, indicating that a midgut barrier affected vector competence in these species. Psorophora confinnis was equally susceptible to both IAB and IE viruses, but apparently had a salivary gland barrier, as only 1 of 16 mosquitoes with a disseminated infection transmitted VEE virus by bite.

In simplified experiments, the characteristics of motion of smooth, unrestrained cylinders in contact with a smooth horizontal bed were investigated in flume experiments with steady, uniform flows. Eight cylinders were tested with varying specific gravities and diameters. At low flows, the cylinders follow trends similar to those noted in sediment particle studies. Incipient motion velocities were highest for the heavier cylinders. At high flows, the terminal velocity of the cylinders was limited to 60-80% of the free-stream flow. Potential flow derivations imply a maximum velocity ratio of 71%. Use of potential flow theory was considered valid (as an estimator) based on previous studies of boundary-layer control that suggest the moving surface of the cylinder minimizes the wake downstream of the cylinder, and therefore only a thin boundary layer is present around the cylinder.

The model combines hydraulics, hydrology, and equilibrium partitioning, using site-specific design specifications, weather data, and equilibrium partitioning coefficients from the literature or from sequential batch or column leach tests of dredged material. The hydraulics and hydrology are modeled using Version 3 of the hydrologic evaluation of landfill performance model. The equilibrium partitioning model includes provisions for estuarine sediments that have variable distribution coefficients resulting from saltwater washout. Model output includes contaminant concentrations in the CDF profile, contaminant concentration and mass releases through the bottom of the CDF, and contaminant concentrations and masses captured by leachate collection systems. The purpose of the model is to provide sound information for evaluating the potential leachate impacts on ground water at dredged material CDFs and the effectiveness of leachate control measures.

However, the precise role of DNA melting remains unknown. A series of DNA substrates containing a unique site- specific BPDE-guanine adduct in a region of non- complementary bases were examined for incision by the Escherichia coli UvrBC endonuclease in the presence or absence of UvrA. UvrBC formed a pre- incision intermediate with a DNA substrate containing a 6-base bubble structure with 2 unpaired bases 5' and 3 unpaired bases 3' to the adduct. Formation of this bubble served as a dynamic recognition step in damage processing. UvrB or UvrBC may form one of three stable repair intermediates with DNA substrates, depending upon the state of the DNA surrounding the modified base. The dual incisions were strongly determined by the distance between the adduct and the double- stranded-single-stranded DNA junction of the bubble, and required homologous double-stranded DNA at both incision sites. Remarkably, in the absence of UvrA, UvrBC nuclease can make both 3' and 5' incisions on substrates with bubbles of 3-6 nucleotides, and an uncoupled 5' incision on bubbles of greater than or equal to greater than or equal to 10 nucleotides. These data support the hypothesis that the E.coli and human NER systems recognize and process DNA damage in a highly conserved manner.

Formulas for predicting fluid transport, species elution, and acoustive wave propagation require parameterization of one or both of these properties. We report paired measurements of permeability and capillary rise from snow samples at field sites in Hanover, New Hampshire, and Sleepers River Research Watershed, Danville, Vermont. We augment these data with laboratory tests on sieved snow and glass beads. Our measurements demonstrate a linear relationship between permeability and the ratio of porosity and the square of capillary rise, which we corroborate theoretically using a simple conduit model of the pore space. We propose that scatter in the data results, in part, from the effect of crystal shape on air flow and imbibition contact angle. Since the early measurements and classification schemes of Bader in 1939, many investigators have expanded the database of permeability observations for a wide range of snow types. We summarize these data and report our own recent observations from the New England sites and from an additional site in Manitoba, Canada. Our measurements are in the high range of reported values. However, after normalizing our data by the square of grain diameter, they follow the empirical function of Shimizu fairly closely. This agreement supports our measurements, and demonstrates the usefulness of Shimizu's function for snow types other than the relatively dense, fine-grained snow used in his analysis. Our normalized permeability data for low density snow, as well as the Shimizu function, are below theoretical predictions for suspensions of spheres and infinite cylinders. By extending the model for spheres to oblate spheroids and discs, we estimate permeability that is in closer agreement with our data. We suggest that a decrease in surface-to-volume ratio as snow ages may account for a relative increase in normalized permeability.

Four groups of 8 volunteers were vaccinated intranasally with three doses of vaccine. The vaccine was very well tolerated in all dosing groups, despite the presence of lipo-oligosaccharide in the vaccine at a level of 25% relative to protein. The antibody response as measured by ELISA in serum, saliva and nasal wash fluids was relatively low in all 4 groups, but the induced serum antibodies had strong bactericidal activity. Persistent bactericidal antibodies ( greater than or equal to 4-fold increase) were produced in 75% of the recipients. Some of the bactericidal antibodies were cross reactive against divergent group B strains. Most of the bactericidal antibodies appeared to be specific for PorA and L3,7,9 LOS. The vaccine also produced a local antibody response which was detected in the nasal wash fluids of volunteers. These data suggest that nasal immunization with NOMV is a safe and effective approach to induce systemic and local immunity against the group B meningococcus and deserves further study.

Cytotoxic T lymphocytes (CTLs) to this epitope were induced by immunizing B10.BR mice intravenously with either irradiated Ebola virus or with irradiated Ebola virus encapsulated in liposomes containing lipid A. The CTL response induced by irradiated Ebola virus could not be sustained after the second round of in vitro stimulation of immune splenocytes with the peptide, unless the irradiated virus was encapsulated in liposomes containing lipid A. The identification of an Ebola GP-specific CTL epitope and the requirement of liposomal lipid A for CTL memory recall responses could prove to be a promising approach for developing a vaccine against Ebola virus infection.

AN - 69945634; 10433700 AB - Reactivation of organophosphate (OP)-inhibited acetylcholinesterase (AChE) is a key objective in the treatment of OP poisoning. This study with native, wild-type, and mutant recombinant DNA-expressed AChEs, each inhibited by representative OP compounds, establishes a relationship between edrophonium acceleration of oxime-induced reactivation of OP-AChE conjugates and phosphoryl oxime inhibition of the reactivated enzyme that occurs during reactivation by pyridinium oximes LüH6 and TMB4. No such recurring inhibition could be observed with HI-6 as the reactivator due to the extreme lability of the phosphoryl oximes formed by this oxime. Phosphoryl oximes formed during reactivation of the ethoxy methylphosphonyl-AChE conjugate by LüH6 and TMB4 were isolated for the first time and their structures confirmed by (31)P NMR. However, phosphoryl oximes formed during the reactivation of the diethylphosphoryl-AChE conjugate were not sufficiently stable to be detected by (31)P NMR. The purified ethoxy methylphosphonyl oximes formed during the reactivation of ethoxy methylphosphonyl-AChE conjugate with LüH6 and TMB4 are 10- to 22-fold more potent than MEPQ as inhibitors of AChE and stable for several hours at pH 7.2 in HEPES buffer. Reactivation of both ethoxy methylphosphonyl- and diethylphosphoryl-AChE by these two oximes was accelerated in the presence of rabbit serum paraoxonase, suggesting that organophosphorus hydrolase can hydrolyze phosphoryl oxime formed during the reactivation. Our results emphasize that certain oximes, such as LüH6 and TMB4, if used in the treatment of OP pesticide poisoning may cause prolonged inhibition of AChE due to formation of phosphoryl oximes.

AN - 734183781; 18031167 AB - Solutions of modified haemoglobin and perfluorocarbon emulsions are currently being tested in advanced human trials. Concerns about renal injury and hypertension with the haemoglobin solutions, and drug retention and pulmonary injury with the perfluorocarbons have been successfully addressed. However, newly recognised inflammatory toxicities of the haemoglobin solutions and the low oxygen-carrying capacity of the perfluorocarbons remain as potential limits on efficacy. As a result, the role of blood substitutes will be less than originally imagined, and none is likely to be licensed for use for several years.

Here we use archived data from the Russian North Pole (NP) drifting stations and our own data from Ice Station Weddell (ISW) to investigate this coupling. Both Arctic and Antarctic distributions of total cloud amount are U-shaped: that is, observed cloud amounts are typically either 0-2 tenths or 8-10 tenths in the polar regions. We fitted these data with beta distributions and, using roughly 70 station-years of observations from the NP stations, compute fitting parameters for each winter month. Although we find that surface-layer air temperature and total cloud amount are correlated, it is not straightforward to predict one from the other because temperature is normally distributed while cloud amount has a U-shaped distribution. Nevertheless, we develop a statistical algorithm that can predict total cloud amount in winter from surface-layer temperature alone and, as required, produces a distribution of cloud amounts that is U-shaped. Because sea ice models usually need cloud data to estimate incoming long-wave radiation, this algorithm may be useful for estimating cloud amounts and, thus, for computing the surface heat budget where no visual cloud observations are available but temperature is measured -- from the Arctic buoy network or from automatic weather stations, for example. The incoming long-wave radiation in sea ice models is generally highly parameterized. We evaluate five common parameterizations using data from NP-4, NP-25, and ISW. The formula for estimating incoming long-wave radiation that Koenig-Langlo and Augstein developed using both Arctic and Antarctic data has the best properties but does depend nonlinearly on total cloud amount. This nonlinearity is crucial since cloud distributions are U-shaped while common sources of cloud data tabulate only mean monthly values. Lastly, we therefore use a one-dimensional sea ice model to investigate how methods of averaging cloud amounts affect predicted sea ice thickness in the context of the five long-wave radiation parameterizations. Here, too, Koenig-Langlo and Augstein's formula performs best, and using daily averaged cloud data yields more realistic results than using monthly averaged cloud data that have been interpolated to daily values.

Human vaccine efficacy studies for inhalational anthrax cannot be conducted. The identification of a correlate of protection that predicts vaccine efficacy is crucial for determining the immune status of immunized humans. This surrogate marker of immunity can only be established by using an appropriate animal model. Numerous studies showed that protective antigen (PA) is the principle protective antigen in naturally- or vaccine-induced immunity. However, attempts to correlate the quantity of anti-PA antibodies with protective immunity in the guinea pig model for anthrax and various vaccine formulations have failed. In these studies, we used the licensed anthrax vaccine adsorbed (AVA) in rabbits. Groups of New Zealand white rabbits, 10 or 20 per group, were immunized intramuscularly (two doses, 4 weeks apart) with varying doses of AVA, ranging from a human dose to 1:256 dilution in sterile phosphate-buffered saline (PBS). Control rabbits received PBS/Alhydrogel according to the same schedule. Each rabbit was bled 2 weeks after the second dose, and antibody levels to PA measured by both the quantitative anti-PA IgG ELISA and the toxin-neutralizing antibody (TNA) assay. Rabbits were aerosol-challenged 10 weeks from day 0 with a lethal dose of Ames spores. All the rabbits that received the undiluted and 1:4 dilution of vaccine survived, whereas those receiving the higher dilutions of vaccine (1:16, 1:64 and 1:256) had deaths in their groups. All the controls died. Rabbit survival was compared with the antibody response. Statistical models were used to test for significance of the peak antibody responses to predict survival. Results showed that both the amount of anti-PA IgG and TNA titres present in the sera at the time of the peak antibody response were significant (P < 0 times 0001) predictors of survival. These results demonstrate that the humoral immune response to AVA can predict protection in the rabbit model of inhalational anthrax.

Three min after addition of 100 mu M TPEN, cells began to retract their neurites and lose their characteristic multipolar shape; by 3 - 4 hr of exposure, most cells detached from the substrate, either singly or as variable-sized aggregates. Viability was assessed by monitoring uptake of calcein AM and propidium iodide, fluorescent dyes that served as markers for live and dead cells, respectively. Incubation of cultures in 100 mu M TPEN led to a gradual decrease in the population exhibiting calcein fluorescence (viable cells) and a corresponding increase in the population displaying propidium iodide fluorescence (nonviable cells). Loss of cell viability reached 12% at 8 hr, 61% at 24 hr and 83% by 48 hr. Ultrastructural examination of TPEN-treated cells revealed condensed chromatin and fragmented nuclei, characteristic of apoptosis, as well as plasma membrane defects and organelle swelling, generally associated with necrosis. Addition of an equimolar concentration of Zn super(2+) or Cu super(2+) but not Fe super(2+) or Mn super(2+) prevented morphological abnormalities and cell death.

Test organisms were exposed to sediments spiked with radiolabeled TNT for 28 d, after which time the endpoints of mortality, growth, and reproduction (L. plumulosus only) were assayed and compared against the TNT tissue concentrations as well as the TNT sediment concentrations. Survival was significantly reduced at a tissue concentration of 61 mu g TNT/g wet wt tissue in N. arenaceodentata and at 6.3 mu g TNT/g wet wt tissue in L. plumulosus. The growth end point demonstrated an apparent hormesis effect in both N. arenaceodentata and L. plumulosus with enhancement (significant for N. arenaceodentata) occurring at the lower TNT concentrations. Growth was significantly reduced at the highest TNT exposure of 10.0 mu g TNT/g wet wt tissue in L. plumulosus. Reproduction was significantly reduced at a tissue concentration of 6.3 mu g TNT/g wet wt tissue in L. plumulosus. The results of this study demonstrate that both N. arenaceodentata and L. plumulosus are sensitive to the presence of sediment-associated TNT and that more information is needed about the toxicity of TNT to benthic fauna to facilitate risk assessment and management of TNT-contaminated sites.

There were no gross differences in pathologies detectable in fish from either site, and the major difference found in bullheads at the two sites was in the relative liver weight (RLW). Differential responses of glutathione reductase, glutathione-S-transferase, Se-dependent glutathione peroxidase, Se-independent glutathione peroxidase, and oxidized glutathione have been reported between fish from contaminated and uncontaminated sites in other studies, but no such differences were observed in the present study. Of the oxidative stress biomarkers included in this investigation, only the responses of superoxide dismutase, catalase, and total glutathione appeared to correlate with environmental exposure of brown bullhead to polycyclic aromatic hydrocarbons. Results with single-strand DNA and ethoxyresorufin-O-deethylase were the reverse of what has been reported in most other studies, and may reflect adaptation of the fish at the previously highly contaminated site. The fish at the Black River site appear to have responded to the xenobiotics present in their environment by increasing their overall liver size, thereby increasing the overall amount of enzymes rather than altering the specific activity of a select set of protective enzymes.

One approach to providing erosion protection and stabilization of channel banks, embankments and spill conveyances is with articulated concrete block systems. Numerous articulated concrete block systems are available for bank stabilization. However, prior to field installations few means are available to evaluate how well these block systems perform. To assist the designer in predicting site specific suitability, a series of hydraulic testing protocols have been developed to analyze block system performance. Two articulated block system testing protocols are presented to indicate how block hydraulic characteristics may be determined and provide performance assurance to both the designer and the owner.

AN - 69973814; 10452545 AB - Primary dissociated fetal mouse spinal cord cultures were used to study the mechanisms underlying the differences in persistence of botulinum neurotoxin A (BoNT/A) and botulinum neurotoxin/E (BoNT/E) activities. Spinal cord cultures were exposed to BoNT/A (0.4 pM) for 2-3 days, which converted approximately half of the SNAP-25 to an altered form lacking the final nine C-terminal residues. The distribution of toxin-damaged to control SNAP-25 remained relatively unchanged for up to 80 days thereafter. Application of a high concentration of BoNT/E (250 pM) either 25 or 60 days following initial intoxication with BoNT/A converted both normal and BoNT/A-truncated SNAP-25 into a single population lacking the final 26 C-terminal residues. Excess BoNT/E was removed by washout, and recovery of intact SNAP-25 was monitored by Western blot analysis. The BoNT/E-truncated species gradually diminished during the ensuing 18 days, accompanied by the reappearance of both normal and BoNT/A-truncated SNAP-25. Return of BoNT/A-truncated SNAP-25 was observed in spite of the absence of BoNT/A in the culture medium during all but the first 3 days of exposure. These results indicate that proteolytic activity associated with the BoNT/A light chain persists inside cells for > 11 weeks, while recovery from BoNT/E is complete in < 3 weeks. This longer duration of enzymatic activity appears to account for the persistence of serotype A action.

AN - 69937431; 10438057 AB - We report on the properties of a set of HIV-1 IIIB Env mutants carrying a linear gp41 epitope insertion (LLELDKWASL) in the V1, V2, V3 or V4 variable loop. Insertion of the epitope, which is defined by the HIV-1 neutralizing MAb 2F5, was well tolerated in the V1, V2 and V4 loops, as these mutants were properly expressed, retained reactivity to conformation-dependent monoclonal antibodies and exhibited patterns similar to the parental Env molecule. However, insertion of this epitope in the V3 loop was associated with drastically reduced protein expression. Relative to parental Env molecule, the V1, V2 and V4 insertion mutants demonstrated significantly increased binding to mAb 2F5 in vitro. To evaluate immunogenicity, mice and guinea pigs were immunized with plasmid expression vectors for the mutant proteins. For both mice and guinea pigs, all four mutants elicited anti-gp120 antibody responses. In mice the V1 and V3 insertion mutants, but neither the V2 or V4 insertion mutant nor the parental env, elicited significant titers against the epitope peptide, whereas in guinea pigs, V2 insertion mutant was most effective in eliciting anti-2F5 peptide antibody responses. While original V2 2F5 insertion mutant failed to elicit anti-2F5 peptide responses in mice, studies with 14 additional V2 insertion mutants revealed several insertion sites at which the epitope was able to induce epitope-specific antibody responses. This indicates that the precise position at which the epitope insertion takes place dictates the ability of the mutant to induce the epitope-specific antibody responses. When tested for virus neutralization activity, the guinea pig sera that contain high titers of anti-2F5 peptide antibody failed to enhance the virus neutralizing activity, suggesting that the configuration of 2F5 epitope plays a critical role in inducing neutralizing antibody responses. The results from this study may have potential implications with respect to modification of the HIV-1 Env molecule for the purpose of improving HIV-1 Env immunogenicity.

AN - 69883883; 10398605 AB - Xeroderma pigmentosum (XP) is an autosomal recessive disease characterized by a high incidence of skin cancers. Yeast RAD30 encodes a DNA polymerase involved in the error-free bypass of ultraviolet (UV) damage. Here it is shown that XP variant (XP-V) cell lines harbor nonsense or frameshift mutations in hRAD30, the human counterpart of yeast RAD30. Of the eight mutations identified, seven would result in a severely truncated hRad30 protein. These results indicate that defects in hRAD30 cause XP-V, and they suggest that error-free replication of UV lesions by hRad30 plays an important role in minimizing the incidence of sunlight-induced skin cancers.

AN - 70819831; 10514047 AB - Laboratory tests were conducted to determine the feasibility of making the mosquito ovitrap lethal to Aedes aegypti (L.) when they attempt to oviposit in the trap. Heavy-weight velour paper strips (2.54 x 11 cm) were used as an alternative to the wooden paddle normally provided as a substrate for mosquito oviposition. The paper strips were pretreated with insecticide solutions and allowed to dry before being used in oviposition cups of 473 ml capacity, filled with water initially to within 2.5 cm of the brim. Insecticides chosen for their quick knock-down efficacy were bendiocarb 76% WP (1.06 mg a.i./strip) and four pyrethroids: permethrin 25% WP (0.16 mg a.i./strip), deltamethin 4.75% SC (0.87 mg a.i./strip), cypermethrin 40% WP (2.81 mg a.i./strip), and cyfluthrin 20% WP (0.57 mg a.i./ strip). For experimental evaluation, two oviposition cups (one with an insecticide-treated strip and one with an untreated strip) were placed in cages (cubic 30 cm) with gravid female Ae. aegypti mosquitoes (aged 6-8 days) from a susceptible laboratory strain. Mortality-rates of female mosquitoes were 45% for bendiocarb, 47% for permethrin, 98% for deltamethrin, 100% for cypermethrin, and 100% for cyfluthrin. Young instar larvae added to the treated cups died within 2h. After water evaporation from the cups for 38 days, fresh mosquito females had access to previously submerged portions of the velour paper paddle, and mortality rates of 59% or more occurred. Cups that had water (360 ml) dripped into them, to simulate rain, produced female mosquito mortality rates of > 50% and all larvae died within 3 h of being added. These tests demonstrate that the ovitrap can be made lethal to both adults and larvae by insecticidal treatment of the ovistrip. Field efficacy trials are underway in Brazil to access the impact of this simple, low-cost, environmentally benign approach on populations of the dengue vector Ae. aegypti.

AN - 69903364; 10414066 AB - The U.S. Army's fluid replacement guidelines emphasize fluid replacement during hot weather training to prevent degradation of performance and minimize the risk of heat injury. Little consideration has been given, however, to possible overhydration and development of water intoxication. Sufficient epidemiological evidence is available to demonstrate an increasing incidence of water intoxication during military training. This article summarizes the development and validation of revised fluid replacement guidelines for hot weather training. The end product is an easy-to-read table that provides the user with the appropriate hourly work time and fluid intake to support work during hot weather training. The guidelines include the range of hot weather conditions likely to be encountered during military training and cover a broad range of military activities. It is expected that the revised guidelines will sustain hydration and minimize the number of heat injuries during military training while protecting the soldier from becoming sick from overdrinking.

AN - 69888537; 10411004 AB - We investigated the inflammatory processes that might be associated with the arthrogenic activity of Staphylococcus aureus, the principal causative agent of bacterial arthritis. Human peripheral blood mononuclear cells (PBMC) were stimulated with the staphylococcal toxic shock syndrome toxin-1 (TSST-1) or enterotoxin B (SEB) and the production of chemokines was examined. Both TSST-1 and SEB induced high levels (ng/mL) of MIP-1alpha, MIP-1beta, and MCP-1. The induction of these chemokines occurred mostly by direct stimulation of PBMC with staphylococcal exotoxins (SE), without requiring the intervention of IL-1 and TNF-alpha. The production of SE-induced chemokines was blocked partially by anti-DR and anti-CD2 antibodies. Cell separation revealed monocytes as the cell source of these chemokines. However, addition of purified T cells amplified the levels of chemokine produced, suggesting that cognate interaction of SE bound on antigen-presenting cells with T cells also contributes to chemokine production. The activation and recruitment of leukocytes by these chemokines may contribute to the pathophysiology of septic arthritis caused by staphylococci in humans through tissue injury and the recruitment of T lymphocytes, perhaps also initiating autoimmune responses. Pentoxifylline, an anti-inflammatory agent, completely inhibited the production of these chemokines.

AN - 69870016; 10391869 AB - Tumor necrosis factor alpha (TNF-alpha) is a critical cytokine that mediates the toxic effects of bacterial superantigens like staphylococcal enterotoxin B (SEB) and toxic shock syndrome toxin 1 (TSST-1). Pentoxifylline, an anti-inflammatory agent that inhibits endotoxemia and lipopolysaccharide (LPS)-induced release of TNF-alpha, was tested for its ability to inhibit SEB- and TSST-1-induced activation of human peripheral blood mononuclear cells (PBMCs) in vitro and toxin-mediated shock in mice. Stimulation of PBMCs by SEB or TSST-1 was effectively blocked by pentoxifylline (10 mM), as evidenced by the inhibition of TNF-alpha, interleukin 1beta (IL-1beta), gamma interferon (IFN-gamma), and T-cell proliferation. The levels of TNF-alpha, IL-1alpha, and IFN-gamma in serum after an SEB or TSST-1 injection were significantly lower in mice given pentoxifylline (5.5 mg/animal) versus control mice. Additionally, pentoxifylline diminished the lethal effects and temperature fluctuations elicited by SEB and TSST-1. Thus, in addition to treating endotoxemias, the cumulative in vitro and in vivo data suggest that pentoxifylline may also be useful in abrogating the ill effects of staphylococcal enterotoxins and TSST-1.

AN - 69845926; 10379751 AB - The American Urological Association Prostate Cancer Clinical Guidelines Panel reviewed 12,501 publications on prostate cancer from 1955 to 1992 to determine whether the complication rates of external beam radiation therapy, interstitial radiotherapy and radical prostatectomy have decreased. Complications reported in at least 6 series, study duration and sample sizes were extracted. Year specific study weighted mean patient ages and complication rates were computed. Regression analysis was performed of the study year on weighted mean patient age and complication rate. Study year had a significant effect on mean patient age and rate of the majority of complications examined. Data indicated a gradual increase in study patient age and a simultaneous decrease in complications from 1960 to 1990. Complication rates in the treatment of localized prostate cancer have decreased during the last 20 to 40 years.

AN - 69839326; 10377124 AB - The Shigella flexneri 2a SC602 vaccine candidate carries deletions of the plasmid-borne virulence gene icsA (mediating intra- and intercellular spread) and the chromosomal locus iuc (encoding aerobactin) (S. Barzu, A. Fontaine, P. J. Sansonetti, and A. Phalipon, Infect. Immun. 64:1190-1196, 1996). Dose selection studies showed that SC602 causes shigellosis in a majority of volunteers when 3 x 10(8) or 2 x 10(6) CFU are ingested. In contrast, a dose of 10(4) CFU was associated with transient fever or mild diarrhea in 2 of 15 volunteers. All volunteers receiving single doses of >/=10(4) CFU excreted S. flexneri 2a, and this colonization induced significant antibody-secreting cell and enzyme-linked immunosorbent assay responses against S. flexneri 2a lipopolysaccharide in two-thirds of the vaccinees. Seven volunteers who had been vaccinated 8 weeks earlier with a single dose of 10(4) CFU and 7 control subjects were challenged with 2 x 10(3) CFU of virulent S. flexneri 2a organisms. Six of the control volunteers developed shigellosis with fever and severe diarrhea or dysentery, while none of the vaccinees had fever, dysentery, or severe symptoms (P = 0. 005). Three vaccinees experienced mild diarrhea, and these subjects had lower antibody titers than did the fully protected volunteers. Although the apparent window of safety is narrow, SC602 is the first example of an attenuated S. flexneri 2a candidate vaccine that provides protection against shigellosis in a stringent, human challenge model.

VX is highly adsorptive toward a wide variety of surfaces; this attribute makes detection using gas-phase approaches difficult but renders the compound very amenable to surface detection. An ion trap mass spectrometer, modified to perform SIMS, was employed in the present study. A primary ion beam (ReO (sub 4) (super -) ) was fired on axis through the ion trap, where it impacted the soil particle samples. [VX+H] (super +) , [VX+H] (super +) fragment ions, and ions from the chemical background were sputtered into the gas-phase environment of the ion trap, where they were either scanned out or isolated and fragmented (MS (super 2) ). At a surface concentration of 0.4 monolayer, intact [VX+H] (super +) , and its fragment ions, were readily observable above background. However, at lower concentrations, the secondary ion signal from VX became obscured by ions derived from the chemical background on the surface of the soil particles. MS (super 2) analysis using the ion trap was employed to improve detection of lower concentrations of VX: detection of the (super 34) S isotopic ion of [VX+H] (super +) , present at a surface concentration of approximately 0.002 monolayer, was accomplished. The study afforded the opportunity to investigate the fragmentation chemistry of VX. Semiempirical calculations suggest strongly that the molecule is protonated at the N atom. Deuterium labeling showed that formation of the base peak ion (C (sub 2) H (sub 4) )N(i-C (sub 3) H (sub 7) ) (sub 2) (super +) involves transfer of the amino proton to the phosphonothioate moiety prior to, or concurrent with, C-S bond cleavage. To manage the risk associated with working with the compound, the vacuum unit of the IT-SIMS was located in a hood, connected by cables to the externally located electronics and computer.

One- and two-dimensional sediment transport models are commonly used for predicting sediment scour and deposition. They are adequate for many engineering applications; however, for some problems, only a three-dimensional model should be used. A three-dimensional model is necessary for predicting sediment erosion and deposition whenever significant secondary currents exist, such as in river bends, crossings, distributaries, or diversions. In diversions, for example, the sediment load may not split in the same proportions as the flow. A three-dimensional model can be used to estimate the sediment split. This paper presents a description of the three-dimensional numerical model CH3D-SED and the governing equations for the model. The validation of the model and its application to the Deep Draft Navigation Project on the lower Mississippi River also are presented.

Between 50% and 90% of the bathymetrie variability at this site was explained by alongshore-uniform response over the approximately 1 km alongshore span of the surveys. Although the incident wave height variance was dominated by frequencies at or higher than 1 cycle/yr, more than 80% of the bathymetric variance at all cross-shore locations was explained by frequencies <1 cycle/yr. Interannual cycles consisting of sandbar formation, migration, and decay contributed to the low-frequency variability. The observed behavior can be explained by a simple, heuristic model. The model assumes that bars migrate toward a wave height dependent equilibrium position. This position was shown to coincide with the wave "breakpoint." Additionally, the rate of bar response is taken to be variable and was empirically determined to be proportional to the wave height cubed. The net effect of a variable response rate is to shift the expected long-term mean sandbar position offshore, toward the equilibrium position associated with the largest waves. The model explained up to 80% of the observed bar position time series variance and up to 70% of the variance of bar crest velocity time series, which were extracted from three different sandbars. Characteristic bar response times (related to the inverse of the response rate) were found to be long relative to the characteristic timescale of the forcing (1 year in our case). As a result, transient response (i.e., bar position far from equilibrium) tended to persist for many cycles of the forcing. Transient bar behavior appears in the observations when bars formed near the shoreline or when outer bars decayed and inner bars faced a changed wave climate. While the present model is able to explain the evolution of these transients, it does not contain a mechanism for their introduction. Copyright 1999 by the American Geophysical Union.

This study was undertaken to examine the type, location, and mechanism of injuries sustained by the military HALO parachutist during training. A retrospective study identified 134 parachutists with 141 injuries attributed to HALO training. The most common injuries were fractures (35.5%) and sprains/strains (34.7%). The sites most commonly injured were the lower extremities (52.5%), upper extremities (19.8%), and spine (14.9%). Landing was the most frequently encountered mechanism of injury (61.2%), followed by ground free fall simulation (wind tunnel training) and canopy deployment.

The goal is to provide management decisions that will balance lifetime system reliability and expected life-cycle cost in an optimal manner. This study proposes a system reliability approach for optimizing the lifetime repair strategy for highway bridges. The approach is demonstrated using an existing Colorado State highway bridge. The bridge is modeled as a series-parallel combination of failure modes, and the reliability of the overall bridge system is computed using time-dependent deterioration models and live load models. Based on an established repair criterion, available repair options, repair costs, and updating, the optimum lifetime repair strategy is developed. The sensitivity of the optimum strategy to changes in various problem parameters including the prescribed service life, system failure criterion, and net discount rate is studied. Finally, the conclusions reveal that the proposed approach demonstrates real potential for practical applications, needs frequent updates through inspection, and requires considerable research effort to develop accurate input data.

For projects located in the vicinity of inlets, the complexity in defining magnitudes and pathways of sediment transport increases significantly. A regional approach considering all available data types and their uncertainties, seasonal and yearly variability, and potential variation in assumptions is required to fully characterize conditions at a project area. Recent advances in sediment-budget applications are reviewed herein, and a newly-developed PC-based program, the Sediment Budget Analysis System (SBAS), is presented. The SBAS allows the practitioner to take a regional approach in formulating sediment budgets for inlets and adjacent beaches, while accounting for uncertainties, variability, and ranges associated with values comprising the budget. An example sediment budget for an inlet is developed with SBAS to highlight some of the recent conceptual advances.

Erosion on the west end of the island, some 45 km from the inlet, is being attributed to the jetties. This supposition is the core of their lawsuit against the U.S. Army Corps of Engineers. Long-term shoreline change data were examined for Fire Island to establish shoreline change rates during discrete time intervals and to delineate temporal and spatial behavior of beaches adjacent to Moriches and Fire Island Inlets in order to assess the veracity of this claim. This case study characterizes the nexus of important coastal policy issues, highly charged political agendas, barrier island geomorphology, and data analysis requirements for coastal zone management. Beachfront real estate on Fire Island is valuable and is being encroached by long-term beach erosion. However, this investigation demonstrates that the claims made by Fire Island homeowners that Moriches Inlet is responsible for this beach erosion are misplaced. The erosional influence of Moriches Inlet on shoreline behavior is relatively localized to the eastern segment of the island, which is undeveloped.

This work describes the results of computer simulations in which a floating layer of circular floes, confined in a rectangular channel, is compressed by a pusher plate moving at a constant speed. The accuracy of the simulations is assessed by comparison with a series of similar physical experiments performed in a refrigerated basin. Following this comparison, the computer model is used to perform an extensive series of simulations to explore the effect of variations in channel length and width, the ratio of floe diameter to thickness, floe on floe friction coefficients, and the distribution of floe diameters on the force required to compress the floes. The results show that reducing the aspect ratio of the floes or increasing the friction coefficient increases the force needed to compress the floes. Both changes increase the force by changing the dominant failure mechanism in the layer of floes from rafting to underturning. Increasing channel width reduced the compressive force (per unit channel width) by reducing the relative importance of frictional drag at the channel edges. Last, the results of a simulation using a distribution of floe diameters was indistinguishable from those of a simulation using floes with a single diameter equal to the average diameter of the distribution.

Since direct PCR amplification from teliospores has not been reliable, teliospores first must be germinated in order to obtain adequate DNA. We have routinely surface-sterilized teliospores for 2 min with 0.4% (vol/vol) sodium hypochlorite (NaOCl) to stimulate germination and produce axenic cultures. However, we observed that some spores were killed even with a 2-min NaOCl treatment, the shortest feasible duration. Decreasing the NaOCl concentration in our study from 0.4% to 0.3 and 0.2%, respectively, increased teliospore germination, but treatment times longer than 2 min still progressively reduced the germination percentages. In testing alternative methods, we found 'acidic electrolyzed water' (AEW), generated by electrolysis of a weak solution of sodium chloride, also surface-sterilized and increased the rate of T. indica teliospore germination. In a representative experiment comparing the two methods, NaOCl (0.4%) for 2 min and AEW for 30 min increased germination from 19% (control) to 41 and 54%, respectively, by 7 days after treatment. Because teliospores can be treated with AEW for up to 2 h with little, if any, loss of viability, compared with 1 to 2 min for NaOCl, treatment with AEW has certain advantages over NaOCl for surface sterilizing and increasing germination of teliospores of suspect T. indica.

The project involved the use of various contaminated and waste materials, including a diesel-contaminated soil, a stockpile of asphalt cement, and a stockpile of RAP. These materials were combined and, depending on their location in the pavement structure, were stabilized with an emulsified asphalt cement to produce an improved roadway pavement. Prior to construction, a laboratory analysis was conducted to determine if the asphalt mixture containing the contaminated soil would leach petroleum materials. Toxicity characteristic leaching procedure (TCLP) extract tests on mixtures with and without contaminated materials showed that unacceptable levels of leaching would not occur under the conditions simulated in the laboratory. The RAP material was processed with a crusher to obtain a uniform-sized material. The crushed RAP was then mixed with the contaminated soil and an asphalt emulsion in a pugmill. This mixture was then placed and compacted using conventional asphalt-concrete paving equipment. The use of the materials at this site for pavement construction resulted in substantial savings when considering costs for removal and disposal of these materials. These contaminated materials provided a structurally satisfactory material for pavement construction; the roadway continues to perform satisfactorily since its placement, almost four years ago.

AN - 69790638; 10347143 AB - The RAD30 gene of Saccharomyces cerevisiae encodes a DNA polymerase, Poleta. The Rad30 protein shares homology with the yeast Rev1 and the Escherichia coli DinB and UmuC proteins. Although these proteins contain several highly conserved motifs, only Rad30 has been shown to possess a DNA polymerase activity. To determine whether the DNA polymerase activity of Rad30 was essential for its biological function, we made a mutation in the highly conserved SIDE sequence in Rad30, in which the aspartate and glutamate residues have each been changed to alanine. The mutant Rad30 protein lacks the DNA polymerase activity, and the mutant gene does not complement the rad30Delta mutation. These findings indicate that DNA polymerase activity is indispensable for the biological function of RAD30.

AN - 85318905; pmid-10499121 AB - A manufacturer-sponsored clinical trial was conducted of ReSound Corporation's IC4 hearing device (HD), an in-the-ear application of their two-channel, fast-acting, wide-dynamic range compression sound processor. This study was a follow-up to an earlier clinical trial of ReSound's behind-the-ear version of the same sound processor, the BT2 Personal Hearing System (Walden, B. E., Surr, R. K., Cord, M. T., & Pavlovic, C. V. (1998). A clinical trial of the ReSound BT2 Personal Hearing System. American Journal of Audiology, 7, 85-100). Forty adult males with gradually sloping, moderate sensorineural hearing losses participated. All were experienced hearing aid users who wore linear Class D instruments with input compression limiting at the time of their enrollment in this study. The Connected Speech Test, presented at several presentation levels and under various conditions of signal degradation, and the scales and subscales of the Profile of Hearing Aid Benefit were used to evaluate hearing aid performance and benefit under four relatively independent prototype listening situations (Walden, B. E., Demorest, M. E., & Hepler, E. L. (1984). Self-report approach to assessing benefit derived from amplification. Journal of Speech and Hearing Research, 27, 49-56). Aided performance with the IC4 HD was compared with (a) unaided performance, (b) performance of persons with normal hearing, and (c) performance with linear amplification. Participants with hearing loss obtained significant benefit from the IC4 HD, although IC4-aided performance remained well below that of unaided performance of persons with normal hearing, especially on laboratory measures of speech recognition. Furthermore, small mean performance advantages were observed for the IC4 HD compared to linear hearing aids, although there was substantial variability across participants. Finally, when given a choice to either purchase the IC4 HD at a discount from the manufacturer or continue using their own government-issued linear hearing aids, the majority of the participants chose to purchase the IC4 HD.

AN - 69913096; 10416276 AB - An acute toxic interaction has been described, in which sublethal doses of pyridostigmine bromide (PB) and the insect repellent N,N-diethyl-m-toluamide (DEET), when administered concomitantly, resulted in seizures and lethality. To investigate the possible relationships between seizures and lethality and the role of the cholinergic system in this interaction, PB (5 mg/kg), DEET (200 mg/kg) or PB (3 mg/kg) + DEET (200 mg/kg) were administered i.p. to male ICR mice, alone or following i.p. pretreatment, with one of several anticonvulsant agents: diazepam, 10 mg/kg; fosphenytoin, 40 mg/kg; phenobarbital, 45 mg/kg; or dextrophan, 25 mg/kg), or the anticholinergic agents, atropine (5 mg/kg), atropine methyl nitrate (2.7 mg/kg), or mecamylamine (2.5 mg/kg). The anticonvulsants selected for this study act through different mechanisms to reduce seizures. None of the anticonvulsants was able to reduce the incidence of seizures following treatment with PB, DEET or PB + DEET. Only diazepam delayed the onset of seizures. Fosphenytoin or diazepam significantly prolonged the time to lethality following PB, but only fosphenytoin reduced the incidence of PB-induced lethality. Diazepam or phenobarbital significantly prolonged the time to lethality following PB + DEET. Both atropine and atropine methyl nitrate protected against PB and PB + DEET-induced lethality and PB-induced seizures. Neither agent blocked seizures resulting from DEET or PB + DEET. Mecamylamine reduced seizures and lethality in PB-treated mice, but not in mice treated with DEET or PB + DEET. The results indicate that seizure activity is not a causative factor in the toxic interaction between PB and DEET. Furthermore, PB, DEET and PB + DEET induce seizures that are resistant to standard anticonvulsants, and each appears to operate through different mechanisms to produce seizures. Peripheral muscarinic receptors may play a specific role in lethality caused by PB + DEET.

AN - 69881476; 10403340 AB - In an attempt to improve the current live-attenuated vaccine (TC-83) for Venezuelan equine encephalitis (VEE), specific mutations associated with attenuation of VEE virus in rodent models were identified. These mutations were inserted into full-length cDNA clones of the Trinidad donkey strain of VEE virus by site-directed mutagenesis, and isogenic virus strains with these mutations were recovered after transfection of baby hamster kidney cells with infectious RNA. We evaluated 10 of these strains for their ability to replicate in and be transmitted by Aedes taeniorhynchus, a natural vector of epizootic VEE virus. Two vaccine candidates, one containing a deletion of the PE2 furin cleavage site, the other a combination of three separate point mutations in the E2 glycoprotein, replicated in mosquitoes and were transmitted to hamsters significantly less efficiently than was either parental (wild type) VEE virus or TC-83 virus. Although the attenuated strains were transmitted to hamsters by mosquitoes, after intrathoracic inoculation, there was no evidence of reversion to a virulent phenotype. The mutations that resulted in less efficient replication in, or transmission by, mosquitoes should enhance vaccine safety and reduce the possibility of environmental spread to unintentional hosts.

AN - 69809607; 10334842 AB - A method is described for the design, evaluation, and application of internal control targets and probes for use in probe-based nucleic acid diagnostic assays (i.e., PCR-ELISA). The technique is a modified version of oligonucleotide-directed mutagenesis in conjunction with PCR amplification to develop a novel probe-annealing sequence in a cloned IS1111a gene fragment of Coxiella burnetii. The internal control probe-recognition site with its complementary probe was identical to the wild-type-specific probe in length, base composition, location, and annealing temperature. Neither the internal control nor the wild-type probes annealed to the recognition sequence of the other. As both of the amplified nucleic acid fragments, internal control and wild type, were identical in length and base composition, the amplification conditions for the diagnostic assay were not affected. This allowed small copy numbers of the internal control clone to be loaded into a diagnostic assay without negatively affecting it. In a single reaction we were able to differentiate between an assay reporting a true or false-negative signal. A negative signal is defined as the absence of detectable pathogen genetic material (true) or inhibition/failure of the reaction (false).

Breton Sound estuary encompasses 1100 km (super 2) of fresh and brackish, rapidly subsiding wetlands. Nitrite + nitrate, total Kjeldahl nitrogen, ammonium, total phosphorus, total suspended sediments, and salinity concentrations were monitored at seven locations in Breton Sound from 1988 to 1994. Statistical analysis of the data indicated decreased total Kjeldahl nitrogen with associated decrease in total nitrogen, and decreased salinity concentrations in the estuary due to the diversion. Spring and summer water quality transects indicated rapid reduction of nitrite + nitrate and total suspended sediment concentration as diverted Mississippi River water entered the estuary, suggesting near complete assimilation of these constituents by the ecosystem. Loading rates of nitrite + nitrate (5.6-13.4 g m-2 yr (super -1) ), total nitrogen (8.9-23.4 g m (super -2) yr (super -1) ), and total phosphorus (0.9-2.0 g m (super -2) yr (super -1) ) were calculated along with removal efficiencies for these constituents (nitrite + nitrate 88-97%; total nitrogen 32-57%; total phosphorus 0-46%). The low impact of the diversion on water quality in the Breton Sound estuary, along with assimilation of TSS over a very short distance, suggests that more water may be introduced into the estuary without detrimental affects. This would be necessary if freshwater diversions are to be used to distribute nutrients and sediments into the lower reaches of the estuary, in an effort to compensate for relative sea-level rise, and reverse the current trend of rapid loss of wetlands in coastal Louisiana.

Approximate mass balance between updrift accumulation and downdrift erosion, which served as an indicator of reliability, was obtained in four of the six runs, which were subjected to further analysis. Magnitudes of three of the four transport rates were considerably lower than predictions by the Coastal Engineering Research Center formula calculated based on contemporaneous measurements of the breaking waves. Error analysis indicated that the determination of the longshore wave-energy flux factor carried a 22-48% maximum uncertainty, and the measured volume-change rate carried a 22-43% uncertainty. The combined uncertainties produce a 40-90% maximum uncertainty in determination of the empirical transport coefficient K appearing in the Coastal Engineering Research Center formula. Comparable or greater uncertainty in K-values probably exists in the total database available for calibrating predictive formulas. The range in values of K in these measurements cannot be explained by measurement error or uncertainty.

The hypothesis was that the extent of mass-dependent fractionation could improve estimates of average pre-entry composition. Studies of siliceous micrometeorites implies that they must have frozen before much evaporation could occur. Results limit the extent of open-system evaporation of Mg to approximately 10% and can be used to interpret time temperature histories. JF - Papers Presented to the ...

It has been changed from a multi-channeled meandering river with islands, sandbars, and a diverse floodplain to a straighter and shorter navigation channel resembling a wide canal through cornfields. Its flow regime has changed from semiannual flooding causing dramatic channel realignments followed by drying through the fall and winter, to one of greatly diminished peakflows and two regulated flow ranges through the year. Direct and indirect habitat losses include 100,000 acres aquatic, 88,000 acres riparian, and 364,000 acres of meander belt. The Missouri's biological standing crop has declined by perhaps 80%, several species have become endangered, benthos habitat has declined by 65%, and floodplain wetlands and forests have nearly vanished. Two bird species are threatened or endangered and others may soon be.

In this study a two-dimensional computer model of the rafting and ridging process is used to simulate a situation in which two identical ice sheets are pushed together at constant speed. Each model ice sheet is composed of two thicknesses of ice. The ratio of the thicknesses is varied to obtain degrees of inhomogeneity. The accuracy of the simulations is assessed by comparison with a series of similar physical experiments performed in a refrigerated basin. Following this comparison, the computer model is used to perform an extensive series of simulations to explore the effect of the thickness and the thickness inhomogeneity of the model ice sheets on the likelihood of occurrence of ridging and rafting. During the simulations the energy consumption and forces are explicitly calculated. The energy consumed during the simulations is used to demonstrate the smooth transition between ridging and rafting that occurs when the homogeneity of the sheets is varied.

In the laboratory, overall behavior of eight A. p. plicata was virtually unaffected by exposure once every 2 hr to a 5-min pulse of high-velocity water (45 cm/s) created with a submersible pump. In the east channel of the upper Mississippi River near Prairie du Chien, WI, multiple passes of recreational craft reduced by only a few percent the total time that six A. p. plicata were opened during a 2-hr period. Only six of 42 events, caused by passage of a work boat or a 6.5-m-long skiff, caused a measurable response in mussel shell gape. It was concluded that A. p. plicata was not greatly affected by brief changes in ambient water velocity caused by vessel passage.

Ambient water velocity was set to 11 cm times s super(-1), with regular 5-minute pulses of 45 cm times s super(-1) occurring every 0.5, 2.0, or 5.0 hours. After 49 days mussels showed no significant inter-treatment differences in respiration, nitrogen excretion, O:N ratio, or tissue condition index. Additional short-term (14 days) laboratory experiments indicated additive effects of increased total suspended solids (TSS) during brief, intermittent periods of high water velocity. The 5-minute episodes of high velocity (50 cm times s super(-1)) occurred once every 0.5 and 3.0 hours against an ambient velocity of 7 cm times s super(-1). TSS rose from an ambient concentration of 20 mg times liter super(-1) to 120 mg times liter super(-1) during the episodes of high velocity. Significantly lower nitrogen excretion and higher O:N tended to occur in high versus ambient TSS treatments; however, these differences were small and inconsistent both among species within a treatment and among treatments for a particular species.

Many previously-unknown environmental problems related to chemicals are surfacing. White phosphorus, a chemical commonly used as an obscurant, is a chemical previously thought to be innocuous after use. In 1990, however, it was linked to the deaths of thousands of waterfowl at the Eagle River Flats impact area on Ft Richardson near Anchorage, Alaska, USA, and shortly after, a series of remedial investigations was initiated. This paper describes three of the remedial methods currently under investigation, namely enhanced in-situ remediation, pond draining through ditching or pumping, and dredging. These three approaches are best applied in different environments, but they can be used together or in conjunction with other strategies. Their impacts on the environment will vary as well. Experience with these remediation strategies has proven very useful in determining the direction that the clean-up effort at Eagle River Flats (ERF) should take. Dredging, an effective means of removing contaminated sediments for off-site remediation, has been shown to be too slow and expensive at the ERF because unexploded ordnance is present. Enhanced natural remediation is effective under favourable climatological conditions in areas that experience intermittent flooding, but desaturation of the sediments is critical to its effectiveness. Pond draining by blasting a ditch effectively removes waterfowl feeding habitat, but attenuation of the contaminant is inhibited because the ditch increases flooding frequency, and the habitat alteration is permanent. Pond pumping, where feasible, has shown great potential for the desaturating of wide areas of ERF, enabling the natural attenuation mechanism to progress. Further investigation will be necessary to confirm these initial conclusions and determine the overall effectiveness of all three methodologies. Methods developed over the course of this work may be applied to other remediation projects where in-situ volatilization can occur and limited disturbance of wetlands is critical.

Managers attempting to plant mangrove in sites containing artificial substrates must remove substrates or risk poor performance of rehabilitation efforts. This study compared propagule retention, early survival, growth, flowering success, and nutrient concentrations of Avicennia marina (grey mangrove) grown on sand, naturally occurring substrate, and rock blast furnace slag over two growing seasons at an experimental site near Newcastle, Australia. Nutrient concentrations of experimental plants were also compared to those of naturally occurring plants. Experimental results showed significant differences (p < 0.05) in short-term survival, growth over the two growing seasons, and carbon and nitrogen concentrations between plants grown on different substrates. Comparison of plants grown in slag and plants from reference sites suggests, however, that slag does not lead to anomalies in nutrient concentrations of young mangroves. Although the results identified some differences between plants grown on river sand, naturally occurring substrate, and slag substrate, the absence of consistent differences suggests that mangroves planted in slag are under no greater risk of future failure than mangroves planted in naturally occurring substrate.

To develop pretreatments that might be useful against CN, SSDs with greater lipophilicity than thiosulfate were synthesized and assessed. The ability of SSDs to protect mice against 2LD sub(50) of sodium cyanide (NaCN) administered either 15 or 60 min following administration of an SSD was assessed. To study the mechanism of action of the SSD, the candidate compounds were examined in vitro for their effect on rhodanese and 3-mercaptopyruvate sulfurtransferase (MST) activity under increasing SSD concentrations. Tests were conducted on nine candidate SSDs: ICD1021 (3-hydroxypyridin-2-yl N-[(N-methyl-3-aminopropyl)]-2-aminoethyl disulfide dihydrochloride), ICD1022, (3-hydroxypyridin-2-yl N-[(N-methyl-3-aminopropyl)]-2-aminoethyl disulfide trihydrochloride), ICD1584 (diethyl tetrasulfide), ICD1585 (diallyl tetrasulfide), ICD1587 (diisopropyl tetrasulfide); ICD1738 (N-(3-aminopropyl)-2-aminoethyl 2-oxopropyl disulfide dihydrochloride), ICD1816 (3,3'-tetrathiobis-N-acctyl-L-alanine), ICD2214 (2-aminoethyl 4-methoxyphenyl disulfide hydrochloride) and ICD2467 (bis(4-methoxyphenyl) disulfide). These tests demonstrated that altering the chemical substituent of the longer chain sulfide modified the ability of the candidate SSD to protect against CN toxicity. At least two of the SSDs at selected doses provided 100% protection against 2LD sub(50) of NaCN, normally an LD sub(99). All compounds were evaluated using locomotor activity as a measure of potential adverse behavioral effects. Positive hypoactivity relationships were found with several disulfides but none was found with ICD1584, a tetrasulfide. Separate studies suggest that the chemical reaction of potassium cyanide (KCN) and cystine forms the toxic metabolite 2-iminothiazolidine-4-carboxylic acid. An alternative detoxification pathway, one not primarily involving the sulfur transferases, may be important in pretreatment for CN intoxication. Although studies to elucidate the precise mechanisms are needed. it is clear that these newly synthesized compounds provide a new rationale for anti-CN drugs, with fewer side-effects than the methemoglobin formers.

Fluorescein-conjugated benzoylecgonine (FL-BE) and monoclonal antibodies (mAb) against benzoylecgonine (BE) were the reagents used for demonstration. The solid phase consisted of anti-BE mAbs immobilized on the surface of polymethyl methacrylate (PMMA) beads. Free BE in solution competed with FL-BE and reduced bead-bound fluorescence in a concentration-dependent manner. The binding of FL-BE to the anti-BE mAb reached steady-state within minutes. FL-BE was not bound by uncoated beads nor beads coated with non-specific proteins or IgG. The signal-to-noise ratio was 33, and the sensitivity of the assay was 2 ng ml super(-1) for BE. The effective concentration of BE was 1 to 100 ng ml super(-1), with an IC sub(50) value of 12 ng ml super(-1). The mAb showed equal affinities for BE, cocaine, and cocaethylene, but a five order-of-magnitude lower affinity for ecgonine and ecgonine methylester. In a double-blind comparison using clinical urine samples, the data from this single-step competitive assay had excellent agreement with results obtained using a fiber-optic biosensor (FOB), and the EMIT assay performed commercially. The assay provided kinetic data rapidly and can be used to detect small analytes for which antibodies and fluorescein conjugates are available. The affinity of the mAb for FL-BE, calculated from kinetic analysis of the time course of the on and off reaction, was 2.25 x 10 super(-9) M.

To ascertain the complexity of the library, nucleotide sequences of the variable regions of the HC and LC genes were determined. Fourteen distinct HC and 18 distinct LC (7 Kappa and 11 lambda ) that formed a combinatorial library of 22 Fabs were identified. Immune-precipitation of radiolabeled VACV revealed that at least six different VACV proteins were recognized by the antibodies. Plaque-reduction neutralization demonstrated that six of the Fabs neutralized VACV in the presence of anti-human antibody. ELISA studies indicated that 15 of the Fabs were cross-reactive with monkeypox virus.

AN - 69919079; 10421483 AB - Enzymes catalyzing the hydrolysis of highly toxic organophosphorus compounds (OPs) are classified as organophosphorus acid anhydrolases (OPAA; EC 3.1.8.2). Recently, the genes encoding OPAA from two species of Alteromonas were cloned and sequenced. Sequence and biochemical analyses of the cloned genes and enzymes have established Alteromonas OPAAs to be prolidases (E.C. 3.4.13.9), a type of dipeptidase hydrolyzing dipeptides with a prolyl residue in the carboxyl-terminal position (X-Pro). Alteromonas prolidases hydrolyze a broad range of G-type chemical warfare (CW) nerve agents. Efforts to over-produce a prolidase from A. sp.JD6.5 with the goal of developing strategies for long-term storage and decontamination have been successfully achieved.

AN - 69918877; 10421484 AB - We previously demonstrated that a combination of cholinesterase (ChE) pre-treatment with an oxime is an effective measure against soman and sarin. We describe here a novel approach for the preparation of covalently linked ChEs which are immobilized to a polyurethane matrix. Such preparation of ChE-sponges enhances the stability and usefulness of the enzymes in non-physiological environments. The ChE-sponges, which can be molded to any form, can effectively be used to remove and decontaminate organophosphates (OPs) from surfaces, biological (skin or wounds) or otherwise (clothing or sensitive medical equipment), or the environment. The ChE-sponges retained their catalytic activity under conditions of temperature, time, and drying where the native soluble enzyme would rapidly denature, and can be reused in conjunction with oximes many times. The ChE-sponge in the presence of oxime repeatedly detoxified OPs such as DFP or MEPQ. These developments in ChE technology have extended the applicability of OP scavengers from in vivo protection, to a variety of external detoxification and decontamination schemes. In addition to treatment of OP-contaminated soldiers, the ChE-sponge could protect medical personnel from secondary contamination while attending chemical casualties, and civilians exposed to pesticides or highly toxic nerve agents such as sarin.

AN - 69771971; 10233419 AB - We performed a prospective infectious natural history study of 21 patients with low-grade lymphoproliferative disorders receiving fludarabine as initial (n = 5) or salvage (n = 16) therapy. 12 (57%) of these patients developed herpes zoster (n = 9), herpes simplex I (n = 1) or herpes simplex II (n = 2) infections at a median of 8 (range 1-17) months following initiation of fludarabine, with 75% of these having completed therapy. All patients with herpes zoster developed severe post-herpetic neuralgia. Factors differentiating patients developing these infections included older age and low serum IgG or IgA. Based upon these prospective data, we conclude that herpes virus infections frequently occur following fludarabine treatment, necessitating aggressive patient education and new prophylactic strategies.

AN - 69741977; 10234473 AB - The hairless guinea pig (HGP) is used by our laboratory to model the human cutaneous response to sulfur mustard (HD), bis(2-chloroethylsulfide), exposure. We determined the HD content in the skin of HGP after a 7-min exposure to vapors saturated with a mixture of HD and 14C-HD. Concentration/time (CT) values in the range of 2 micrograms/cm2/min were determined by counting skin 14C disintegrations per min (dpm) in animals euthanized immediately after exposure. These values are similar to human penetration rates obtained by other investigators. A rate curve monitoring the reduction in skin 14C dpm was developed for animals euthanized between 0 and 24 hr post- exposure. This curve showed the greatest change after 1 hr. The epidermal (62%) to dermal (38%) ratio of 14C at 24 hr was measured for two animals. We saw no site preference for HD penetration among the 8 sites used. The 14C content of template adhesive tape was determined to follow HD distribution. These results contribute to a better understanding of the cutaneous response to HD in the HGP model.

The source of the bumps appeared to be expansion within the cement-stabilized base course. Laboratory examination of samples from areas showing distress revealed the presence of ettringite, a calcium sulfoaluminate the formation of which can be accompanied by severe expansion. This expansive material was the probable cause of the volume changes causing the transverse bumps. The calcium and alumina needed to form ettringite were available from the portland cement and the stabilized soil's clay minerals. The source of the sulfur was identified as the well water that was mixed with the cement-stabilized base. Sulfate attack of cement-stabilized soils is a relatively infrequent problem, but it is highly destructive when it occurs. Currently, there are no firm criteria for identifying when sulfate attack of a cement-stabilized soil is a potential problem nor are there established methods of preventing the attack.

We further hypothesized that an increased exercise Sa sub(O2) with AA exposure would enhance O sub(2) transport and improve both peak O sub(2) uptake (VO sub(2 peak); ml times kg super(-1) times min super(-1)) and submaximal exercise time to exhaustion (Exh; min) in the midluteal phase. Eight female lowlanders [33 plus or minus 3 (mean plus or minus SD) yr, 58 plus or minus 6 kg] completed a VO sub(2 peak) and Exh test at 70% of their altitude-specific VO sub(2 peak) at SL and with AA exposure to 4,300 m in a hypobaric chamber (446 mmHg) in their early follicular and midluteal phases. Progesterone levels increased (P < 0.05) similar to 20-fold from the early follicular to midluteal phase at SL and AA. Peak VE (101 plus or minus 17) and submaximal VE (55 plus or minus 9) were not affected by cycle phase or altitude. Submaximal Sa sub(O2) did not differ between cycle phases at SL, but it was 3% higher during the midluteal phase with AA exposure. Neither VO sub(2 peak) nor Exh time was affected by cycle phase at SL or AA. We conclude that, despite significantly increased progesterone levels in the midluteal phase, exercise VE is not increased at SL or AA. Moreover, neither maximal nor submaximal exercise performance is affected by menstrual cycle phase at SL or AA.

AN - 17372566; 4595047 AB - Tiger salamanders (Ambystoma tigrinum) were exposed via soil and/or food (earthworms) to 2,4,6-trinitrotoluene (TNT) and a PCB mixture (Aroclor 1260) at environmentally relevant concentrations. Four exposures were considered: (1) uncontaminated food + uncontaminated soil (control group); (2) contaminated soil + uncontaminated food (dermal group); (3) contaminated food + uncontaminated soil (oral group); and, (4) contaminated soil + contaminated food (dual-exposure group). The chemical exposure was estimated for each group by analysis of both soil and earthworms. Body burdens of TNT and its primary metabolites were highest in the dermal groups while PCB burdens were highest in the oral groups. Concentrations of the primary TNT metabolites evaluated, 2-amino-dinitrotoluene (DNT) and 4-amino-DNT, exceeded that of unmetabolized TNT and accumulated to 116 and 670 ng/g, respectively. These results provide evidence that dermal exposures to nitroaromatics in terrestrial salamanders may make an important contribution to total body burden and thus may be important when considering the health consequences of such exposures. Further, the demonstration of the accumulation of TNT and TNT metabolites in a primitive vertebrate may have food web modeling implications.

We captured 1,293 raccoons and Virginia opossums during the 3-yr study (140 individual raccoons and 160 individual Virginia opossums) with 1,895 adult D. variabilis collected. Raccoons had a significantly higher mean intensity and higher prevalence of adult ticks than Virginia opossums (Mann-Whitney Z = 6.15, chi super(2) = 51.9, P < 0.001). Mean intensity follows Margolis et al. (1982) as being the mean number of parasite species per infected host. Prevalence follows Margolis et al. (1982) as being the number of individuals of the host species infected with a parasite species divided by the number of hosts examined. The time required for a higher prevalence and mean intensity of ticks to occur on raccoons than Virginia opossums was <7 d. No significant differences occurred between the mean intensity or prevalence of D. variabilis between sexes or among age classes of raccoons. Significant differences in prevalence and mean intensity of ticks occurred between sexes and among age classes of Virginia opossums. Infestation increased by 0.64 ticks per day on Virginia opossums and 1.77/d on raccoons during the first 7 d. The base host finding rate (ticks per host per day) of adult D. variabilis on Virginia opossums was 0.064 and 0.053 on raccoons. Tick interactions with hosts are quantified and may reflect behavioral differences between sexes and among age groups intraspecifically, and host preferences of adult D. variabilis interspecifically.

AN - 69698347; 10206993 AB - We have probed an epitope sequence (His18-Pro19-Lys20-Phe21) in interleukin-8 (IL-8) by site-directed mutagenesis. This work shows that single and double Ala substitutions of His18 and Phe21 in IL-8 reduced up to 77-fold the binding affinity to IL-8 receptor subtypes A (CXCR1) and B (CXCR2) and to the Duffy antigen. These Ala mutants triggered neutrophil degranulation and induced calcium responses mediated by CXCR1 and CXCR2. Single Asp or Ser substitutions, H18D, F21D, F21S, and double substitutions, H18A/F21D, H18A/F21S, and H18D/F21D, reduced up to 431-fold the binding affinity to CXCR1, CXCR2, and the Duffy antigen. Interestingly, double mutants with charged residue substitutions failed to trigger degranulation or to induce wild-type calcium responses mediated by CXCR1. Except for the H18A and F21A mutants, all other IL-8 mutants failed to induce superoxide production in neutrophils. This study demonstrates that IL-8 recognizes and activates CXCR1, CXCR2, and the Duffy antigen by distinct mechanisms.

Despite numerous publications on the subject, there is as yet no clear consensus on the mathematical model of soil freezing. In this report a mathematical model called M (sub 1) is presented. The existence of traveling wave solutions to the problem is shown. For a given fine-grained soil, such solutions are shown to exhibit three distinct behaviors depending on given thermal and hydraulic conditions. When a frost front (0 degrees C isotherm) advances, water is either attracted to the front or expelled from it. Under certain conditions an ice layer containing hardly any soil particles grows. The report describes how the traveling wave solutions have been used for the empirical verification of M (sub 1) .

AN - 69723535; 10223271 AB - The majority of military physiological studies have been conducted on men. Consequently most physiological modeling is based on male performance. This study obtained data on women performing military tasks under hot-dry field conditions. Results for rectal temperature (Tre) and heart rate (HR) were compared with values generated by the SCENARIO physiological model. Three skin surface temperatures, Tre, and HR were collected while four female subjects participated in walking or two-person litter carriage (68 kg load) in regular battledress and with full chemical protection at Yuma Proving Ground, AZ. Metabolic rates were measured prior to the test days. Meteorological data were also recorded. Overall, the potential for thermal stress decreased over the four test days, with air temperature dropping from 39.4 degrees to 35.5 degrees C. Whole body metabolic values were 364 W (walking), 91 W (standing), and 492 W (litter carriage). Endurance times (160 min maximum) for walking were 140 min in Mission Oriented Protective Posture (MOPP)-0 and 29 min in MOPP-4. For litter carriage, the average times were 59 min in MOPP-0 and 43 min in MOPP-4. A comparison of root mean squared deviation (RMSD) to the mean standard deviation for Tre demonstrated a good fit between the model and mean observed values for the MOPP-0 condition. Observed HRs were greater than predicted by the model. The modeling results support a conclusion that factors other than heat stress limited litter carriage in MOPP-0. Analysis of calculated values for Tre using RMSD supports an assumption that the male-based SCENARIO may be applicable to females.

Today's miniregional Great Plains Sociological Assoc, through its refereed publication, The Great Plains Sociologist (TGPS), maintains a variant of this tradition. Examined here is the first decade (1988-1997) of published articles (N = 52) in TGPS, with a focus on authorship, affiliations, editorship, & components of the earliest Chicago sociology & its diffusion to the U of North Dakota & the region through the work of John Morris Gillette. Results show that TGPS is a unique publication representing empirical research on homespun social issues using local samples by sociologists & criminologists affiliated with a range of colleges & universities in & around the Dakotas. A sociology of the Great Plains is emerging. Implications for the journal, state & miniregional associations, & the discipline are discussed. 1 Table, 1 Chart, 55 References.

In this work, the problem of water expulsion is studied analytically based on a mathematical model called M (sub 1) . The condition of water expulsion is found to depend on the properties of a given soil, given thermal and hydraulic conditions. The theoretical predictions are compared with data of Kanto loam and the agreement between them is found to be satisfactory.

The tunnel will divert flow from the headwaters of the Passaic to the upper end of Newark Bay. The present study provided information required to evaluate the effect of the tunnel on finfish and shellfish in the vicinity of the outlet. Impacts were examined through the CH3D hydrodynamic model and the CE-QUALICM water-quality model. Quantities computed included tides, currents, salinity, temperature, dissolved oxygen (DO), and biochemical oxygen demand. The models were calibrated to field data collected from July to September 1994. Scenarios illustrated the impact of the tunnel on salinity, temperature, and DO under three flow conditions. In the worst case, impact of the tunnel on DO and temperature was short-lived and of limited spatial extent. Impact of the tunnel on salinity was indiscernible.

We use a wide-ranging set of snow and meteorological data collected at 3-hourly intervals on NP-4 during this period to investigate energy and mass transfer in the snow, sea ice, and atmospheric surface layer in the central Arctic. SNTHERM, a one-dimensional energy and mass balance model, synthesizes these diverse NP-4 data and thereby yields energetically consistent time series of the components of the surface heat budget. To parameterize the sensible heat flux during extremely stable stratification, we replace the usual log-linear stability function with the "Dutch" formulation and introduce a windless coefficient in the bulk parameterization. This coefficient provides sensible heat transfer at the surface, even when the mean wind speed is near zero, and thereby prevents the surface temperature from falling to unrealistically low values, a common modeling problem when the stratification is very stable. Several other modifications to SNTHERM introduce procedures for creating a realistic snowpack that has continuously variable density and is subject to erosion and wind packing. The NP-4 data provide for two distinct simulations: one on 2-year ice and one on multiyear ice. We validate our modeling by comparing simulated and observed temperatures at various depths in the snow and sea ice. Simulations for both sites show the same tendencies. During the summer, the shortwave radiation is the main term in the surface heat budget. Shortwave radiation also penetrates into the snow and causes a subsurface temperature maximum that both the data and the model capture. During the winter, the net longwave balance is the main term in the surface heat budget. The snow and sea ice cool in response to longwave losses, but the flux of sensible heat from the air to the surface mitigates these losses and is thus nearly a mirror image of the emitted longwave flux.

In this study, we evaluated the humoral immune response of mice that survived lethal Y. pestis aerosol challenge after antibiotic treatment. Such a model may replicate the clinical situation in humans and indicate which virulence determinants are expressed in vivo. Immunoglobulin G enzyme-linked immunosorbent assay and immunoblotting were performed by using purified, recombinant antigens including F1, V antigen, YpkA, YopH, YopM, YopB, YopD, YopN, YopE, YopK, plasminogen activator protease (Pla), and pH 6 antigen as well as purified lipopolysaccharide. The major antigens recognized by murine convalescent sera were Fl, V antigen, YopH, YopM, YopD, and Pla. Early treatment with antibiotics tended to reduce the immune response and differences between antibiotic treatment regimens were noted. These results may indicate that only some virulence factors are expressed and/or immunogenic during infection. This information may prove useful for selecting potential vaccine candidates and for developing improved serologic diagnostic assays.

The vaccines were formulated in a double-chamber sachet; one chamber contained lyophilized bacteria, and the other contained buffer. A total of 170 partially-immune American soldiers stationed in Panama received one of the following five formulations: (a) CVD 103-HgR at 10 super(8) CFU plus CVD 111 at 10 super(7) CFU, (b) CVD 103-HgR at 10 super(8) CFU plus CVD 111 at 10 super(6) CFU, (c) CVD 103-HgR alone at 10 super(8) CFU, (d) CVD 111 alone at 10 super(7) CFU, or (e) inactivated Escherichia coli placebo. Among those who received CVD 111 at the high or low dose either alone or in combination with CVD 103-HgR, 8 of 103 had diarrhea, defined as three or more liquid stools. None of the 32 volunteers who received CVD 103-HgR alone or the 35 placebo recipients had diarrhea. CVD 111 was detected in the stools of 46% of the 103 volunteers who received it. About 65% of all persons who received CVD 103-HgR either alone or in combination had a fourfold rise in Inaba vibriocidal titers. The postvaccination geometric mean titers were comparable among groups, ranging from 450 to 550. Ogawa vibriocidal titers were about twice as high in persons who received CVD 111 as in those who received CVD 103-HgR alone (600 versus 300). The addition of CVD 111 improved the overall seroconversion rate and doubled the serum Ogawa vibriocidal titers, suggesting that the combination of an El Tor and a classical cholera strain is desirable. While CVD 111 was previously found to be well tolerated in semiimmune Peruvians, the adverse effects observed in this study indicate that this strain requires further attenuation before it can be safely used in nonimmune populations.

AN - 69623064; 10074406 AB - The apurinic/apyrimidinic endonucleases (APE) contain several highly conserved sequence motifs. The glutamic acid residue in a consensus motif, LQE96TK98 in human APE (hAPE-1), is crucial because of its role in coordinating Mg2+, an essential cofactor. Random mutagenesis of the inactive E96A mutant cDNA, followed by phenotypic screening in Escherichia coli, led to isolation of an intragenic suppressor with a second site mutation, K98R. Although the Km of the suppressor mutant was about sixfold higher than that of the wild-type enzyme, their kcat values were similar for AP endonuclease activity. These results suggest that the E96A mutation affects only the DNA-binding step, but not the catalytic step of the enzyme. The 3' DNA phosphoesterase activities of the wild-type and the suppressor mutant were also comparable. No global change of the protein conformation is induced by the single or double mutations, but a local perturbation in the structural environment of tryptophan residues may be induced by the K98R mutation. The wild-type and suppressor mutant proteins have similar Mg2+ requirement for activity. These results suggest a minor perturbation in conformation of the suppressor mutant enabling an unidentified Asp or Glu residue to substitute for Glu96 in positioning Mg2+ during catalysis. The possibility that Asp70 is such a residue, based on its observed proximity to the metal-binding site in the wild-type protein, was excluded by site-specific mutation studies. It thus appears that another acidic residue coordinates with Mg2+ in the mutant protein. These results suggest a rather flexible conformation of the region surrounding the metal binding site in hAPE-1 which is not obvious from the X-ray crystallographic structure.

Candidate naked DNA vaccines for HFRS were constructed by subcloning cDNA representing the medium (M; encoding the G1 and G2 glycoproteins) or small (S; encoding the nucleocapsid protein) genome segment of SEOV into the DNA expression vector pWRG7077. We vaccinated BALB/c mice with three doses of the M or S DNA vaccine at 4-week intervals by either gene gun inoculation of the epidermis or needle inoculation into the gastrocnemius muscle. Both routes of vaccination resulted in antibody responses as measured by ELISA; however, gene gun inoculation elicited a higher frequency of seroconversion and higher levels of antibodies in individual mice. We vaccinated Syrian hamsters with the M or S construct using the gene gun and found hantavirus-specific antibodies in five of five and four of five hamsters, respectively. Animals vaccinated with the M construct developed a neutralizing antibody response that was greatly enhanced in the presence of guinea pig complement. Immunized hamsters were challenged with SEOV and, after 28 days, were monitored for evidence of infection. Hamsters vaccinated with M were protected from infection, but hamsters vaccinated with S were not protected.

AN - 69724482; 10222572 AB - The combined effects of respirator wear and low-intensity work on decision making and mood were assessed in eight subjects during 60 min of low-intensity treadmill walking with and without a respirator to determine whether the stresses of respirator wear negatively impact decision making. Subjects completed walks during no mask wear, wear of a respirator with high inspiratory resistance, and wear of a respirator with low resistance. Cognitive tasks included choice reaction (CHO), serial addition/subtraction (ADD), logical reasoning (LOG), and serial reaction (SER). Mood was measured using a questionnaire with 36 adjectives representing the factors of activity, anger, depression, fear, happiness, and fatigue. Data were obtained preexercise, after 20 and 40 min of walking, and postexercise. Combined respirator wear and low-intensity exercise did not affect accuracy, speed, or throughout in any of the cognitive tasks. Likewise, no significant effects of condition on the six mood factor scores were observed. These results show that the combination of respirator wear and low-level activity does not adversely alter cognitive performance or mood.

AN - 69621365; 10080352 AB - Clostridium perfringens phospholipase C (PLC), commonly known as alpha toxin, is the lethal, dermonecrotic toxin produced by all strains and is considered a major virulence factor in clostridial myonecrosis. We developed a capture antibody ELISA that accurately and specifically quantitates alpha toxin produced by C. perfringens. Another PLC, derived from Bacillus cereus, and culture filtrates from various bacterial species including Clostridium bifermentans and Clostridium novyi were not cross-reactive in this ELISA. Standard curves generated with homogenous C. perfringens alpha toxin revealed detection limits of 19 ng/ml. The ELISA was more sensitive in detecting alpha toxin than techniques such as PLC enzymatic activity and mouse lethality assays.

AN - 69613500; 10071268 AB - Rituximab was recently approved for use in relapsed, low-grade non-Hodgkin's lymphoma; however, few data exist regarding the safety of this agent in patients with a high number of tumor cells in the blood. After the observation at our institution of a rapid reduction of peripheral-blood tumor cells with associated severe pulmonary infusion-related toxicity in two patients with refractory hematologic malignancies, data on three additional cases were collected from physician-submitted reports of adverse events related to rituximab treatment. Five patients with hematologic malignancies possessing a high number of blood tumor cells were treated with rituximab and developed rapid tumor clearance. The median age was 68 years (range, 26 to 78 years). Patients were diagnosed with B-cell prolymphocytic leukemia (n = 2), chronic lymphocytic leukemia (n = 2), or transformed non-Hodgkin's lymphoma (n = 1). All of these patients had bulky adenopathy or organomegaly. All five patients developed a unique syndrome of severe infusion-related reactions, thrombocytopenia, rapid decrement in circulating tumor cell load, and mild electrolyte evidence of tumor lysis, and all required hospitalization. In addition, one patient developed ascites. These events resolved, and four patients were subsequently treated with rituximab without significant complications. Rituximab administration in patients who have a high number of tumor cells in the blood may have an increased likelihood of severe initial infusion-related reactions. These data also suggest that rituximab may have activity in a variety of other lymphoid neoplasms, such as chronic lymphocytic leukemia and B-cell prolymphocytic leukemia.

AN - 69586140; 10024605 AB - This study describes a quick (<12 h) assay for detecting temperature decreases in BALB/c and C57BL/6 mice injected intraperitoneally (i.p. ) with staphylococcal enterotoxin A (SEA), SEB, or SEC3 or toxic shock syndrome toxin 1 and a potentiating dose of lipopolysaccharide (LPS). Toxin-specific antisera effectively neutralized the temperature fluctuations in this model. Orally administered SEA or SEB (50 microg/animal), with or without LPS, did not have an effect on temperature or lethality. Versus wild-type mice, transgenic knockout mice lacking the p55 receptor for tumor necrosis factor (TNF) or gamma interferon were protected against an i.p. challenge of SEA plus LPS. The p75 receptor for TNF and intercellular adhesion molecule 1 have a negligible role in this toxic shock model.

Part of the remediation site was to be used as a parking area. The stabilized soil was to be covered with natural base/subbase course materials and capped with an asphalt concrete cover. During the course of the remediation, a base-course layer could not be placed prior to the onset of winter. A field study was conducted to quantify any changes in the mechanical properties of the open stabilized subgrade subjected to freeze-thaw cycling during the winter of 1996-97. Field evaluation was conducted with pavement industry tools: the Clegg impact hammer and the dynamic cone penetrometer. Evaluation results show the viability of the Clegg hammer as an instrument for quality assurance and also show that there can be up to 50% loss in compressive strength of the subgrade within the uppermost layer of the material caused by freeze-thaw cycling.

The Hodges Village Dam in Oxford, Mass, is part of an extensive flood control network built and operated by the U.S. Army Corps of Engineers in the Thames River basin of Massachusetts and Connecticut. The dam consists of a relatively homogeneous and pervious sand and gravel embankment on stratified glacial outwash sands, gravels, and cobbles. Because it was designed primarily as a run-of-the-river, flood control facility with no anticipated long-term pool storage, no significant seepage control measures were ever constructed for the dam. This paper describes a series of seepage events that have occurred at the dam starting in 1968 and continuing to 1993. Remediation efforts after each of the events are described as are their effects on dam performance. The paper concludes that the past seepage problems at the dam were caused by assumptions made about foundation soil conditions prior to dam construction, problematic drains and relief wells that resulted in significant head buildups in their respective zones of influence, and insufficient subsurface information prior to design and construction. Investigation and analyses of the dam conducted after the 1993 event are presented, and plans are described for a seepage control remediation project currently under construction.

EM61 geophysical surveys were conducted over portions of the now developed cantonment area as part of a statistically based sampling plan to locate and dig metallic anomalies potentially representing UXO. Select QA/QC aspects of the EM61 based ordnance location and sampling program are presented. Performance testing documents a significant decrease in non-UXO anomalies vs mag-and-flag techniques at this site. EM61 calibration pit results for simulated UXO items and analysis of 10% replicate grid data show acceptable data accuracy, precision, and comparability. Tracking of calibration pit test results show negligible variation of peak amplitudes between instruments, or with variations in temperature and precipitation.

Wind-driven flows in this remote, shallow bay frequently dominate the weak astronomical tide. The bay presently has two connections to the Gulf of Mexico, one through a short flood-relief channel and the other through a long and circuitous navigation channel. The study had to consider whether installation of a third inlet would cause the relief channel to close or increase the already strong current velocity in the navigation channel that is a concern for boating safety. The model was calibrated with measurements of wind, water level, and current taken in this study. It is concluded that the new inlet will be ebb-dominated because of the wind-induced current, and that the relief channel will not close in the presence of the new inlet. In addition, the peak current at a critical maneuvering area in the navigation channel that presently poses a hazard to vessel traffic will be reduced by as much as 25% as a result of opening the new inlet.

The recombinant proteins were purified and injected into mice. Most Yop-vaccinated animals succumbed to infection with either wild-type encapsulated Y. pestis or a virulent, nonencapsulated isogenic variant. Vaccination with YpkA significantly prolonged mean survival time but did not increase overall survival of mice infected with the nonencapsulated strain. The only significant protection against death was observed in YopD-vaccinated mice challenged with the nonencapsulated strain.

Sampling was conducted before, during, and after a daily generation cycle with measurements of temperature, dissolved oxygen, iron, manganese, and turbidity. Temperatures were near 25 degree C during generation, fluctuated 3-4 degree C during nongeneration, and increased in a downstream direction to near 28 degree C. Dissolved oxygen concentrations were between 4 and 6 mg L super(-1) during generation and increased in a downstream direction. During nongeneration, concentrations in the upstream region of the tailwater were near 2 mg L super(-1) but were between 4 and 10 mg L super(-1) in the rest of the study area. Maximum concentrations, 6 to 10 mg L super(-1), were observed prior to the hydrograph peak at each station, suggesting leading edge effects of increased flow and aeration as substrate was covered during river stage increases. Concentrations of metals increased in a downstream direction coincident with turbidity increases from near 3 to 25 NTUs, suggesting resuspension and possibly flocculation. Dissimilar patterns were observed for nongeneration when concentrations decreased in a downstream direction while turbidity was relatively constant and lower than generation values, suggesting settling with decreased flow.

It differs from other natural freezing operations in that it maximizes the amount of sludge that can be frozen. The freezing bed is a particularly attractive alternative for dewatering alum sludge because no conditioning chemicals are required and the remaining granular material can be left to accumulate in the bed for several years. Equations are presented that can be used to size the freezing bed according to local climatic conditions.

Baculoviruses expressing the entire structural protein region (C-E3-E2 6K-E1), or the complete glycoprotein region (E3-E2-6K-E1), generated products in Sf9 cells that were accurately and completely processed, and resulted in mature proteins that were antigenically and electrophoretically indistinguishable from authentic viral proteins. These products were highly immunogenic in BALB/c mice, induced efficient VEE neutralizing responses, and protected these animals against challenge with virulent VEE. Expression of individual glycoprotein regions (E3-E2 and 6K E1) generated products that were accurately but incompletely processed, and induced non-neutralizing antibodies that reacted more efficiently with denatured than native VEE proteins. Nonetheless, immunization with the 6K-E1 expression product provided complete protection against VEE challenge.

To mitigate the problem, a variety of stabilization techniques were evaluated for their suitability for rapid employment to enhance military vehicle operations. A combination of mechanical stabilization methods including several lightweight fills, geosynthetics, and tire and wood mats, were constructed and tested during the annual training exercises of the 229th Engineers of the Wisconsin National Guard during the difficult conditions of spring thaw. The techniques were evaluated for their expediency, ease of construction, trafficability, and durability. In general, chunkwood was an excellent replacement for gravel fill in forested area; tree slash (or other vegetation) was effective but labor intensive; wood mats and pallets were effective and reasonably durable; tire mats were extremely rugged and effective. A loader or crane was needed to place the large wood mats, tire mats, and fascines. Geocomposite materials (Geonet) were quickly installed and could withstand limited traffic (50 passes) without additional cover material. Geosynthetics reduced the amount of cover material and enhanced placement, effectiveness and removal when used under other materials to spread the load and keep them from sinking into the mud. All materials were damaged during the severe motion of a tank cornering except the large, smooth wood mats, but these were slippery on slopes. Results are summarized in a decision matrix for choosing the best technique depending on site conditions, material and equipment availability and utilization criteria.

AN - 69670934; 10189569 AB - Two approaches for evaluating potential health impact from short-term (1 hour) inhalation exposure to air emissions from combustion facilities are presented. This information was included as part of the health risk assessment (HRA) conducted for each proposed facility in conjunction with regulatory requirements for obtaining an operating permit. Since the facilities being evaluated have either not yet been constructed or are not yet operational, air concentrations (particulate and vapor) must first be estimated using data from similar and operational facilities. A chemical's modeled air concentration was then compared to its acute toxicity value (ATV) selected from established Occupational Exposure Limits (OEL) or acute toxicity databases, if available. Analogous to the current USEPA approach for estimating noncancer health effects, acute hazard quotients (AHQs) were summed and compared to a level of one. When the summation of the AHQs exceeded unity, the chemicals were separated by target organ and health effects based on acute exposures. The author recognizes that the use of OELs has its limitations. However, due to the lack of acute toxicity data and the advantage of the completeness of the databases for OELs, this approach may be the best way to evaluate for acute health concerns for the more than 70 compounds that may be emitted from these facilities.

AN - 69670163; 10189580 AB - In 1994, the United States Environmental Protection Agency (USEPA) developed a screening methodology for conducting indirect exposure risk assessments for combustion facilities. The United States Army Center for Health Promotion and Preventive Medicine currently utilizes this methodology in conjunction with other USEPA guidance documents to perform human health risk assessments (HHRAs). The HHRAs require the development of complex human health models using spreadsheet software packages which estimate various media concentrations of contaminants in the environment. Since the quality assurance/quality control procedures associated with verifying the model's results are extremely time consuming, a computer program was developed using Microsoft Excel to minimize the amount of time needed. This discussion describes the 6 steps taken in developing this computer program, which are: (1) understanding the problem; (2) establishing the structure of each table in the spreadsheets; (3) developing an algorithm to solve the problem; (4) writing code; (5) running the program; and (6) testing the results. The automated process of having the computer predict health risk and hazards for each potentially exposed individual saves a tremendous amount of time because each calculated value is placed in the correct spreadsheet cell location. In addition to the time needed to develop human health spreadsheets, this program also minimizes the potential for reducing human error.

AN - 69599135; 10048108 AB - Light infantry soldiers (N = 218) completed a 161-km cross-country march over 5 days carrying an average +/- SD load mass (i.e., the weight of all equipment and clothing) of 47 +/- 5 kg. Prior to the march, height, weight, body fat, and physical fitness (3.2-km run, sit-ups, push-ups) were measured. Soldiers completed a demographic questionnaire which included questions on age and tobacco use history. Thirty-six percent (78/218) of the soldiers suffered one or more injuries. Of the total injuries, 48% presented were blisters and 18% were foot pain (not otherwise specified). Eight percent (17/218) of the soldiers were unable to complete the march because of injuries. Thirty-five percent (27/78) of the injured soldiers had 1 or more limited duty days for a total of 69 days. Risk of injury was higher among smokers (risk ratio = 1.8, P = 0.03 compared to nonsmokers) and lower among older soldiers (risk ratio = 3.2, P = 0.02, 24 years). Carrying heavy loads over long distances can result in a high injury incidence to the lower body, since 36% of soldiers were injured during the 161-km march.

AN - 69597098; 10050563 AB - Three hundred thirty-nine freshmen participating in cadet basic training at the U.S. Military Academy completed a questionnaire that asked them about their previous military experience, gender, ethnicity, injuries and illness experienced in the last 12 months, foot type, cigarette smoking habits, smokeless tobacco use, alcohol consumption, and sleep habits. They then performed a 21-km road march in about 6.5 hours. Their feet were examined for blisters before and after the march. Univariate analysis showed that risk factors for foot blisters included ethnicity (blacks at lower risk than others), a sickness in the last 12 months, no previous active duty military experience, use of smokeless tobacco, and flat feet (pes planus). Logistic regression indicated that all of these were independent blister risk factors with the exception of no previous active duty military experience.

The results show that wind shields improve gauge catch of precipitation, particularly for snow. Shielded gauges, on average, measure 20-70% more snow than unshielded gauges. Without a doubt, the use of wind shields on precipitation gauges has introduced a significant discontinuity into precipitation records, particularly in cold and windy regions. This discontinuity is not constant and it varies with wind speed, temperature, and precipitation type. Adjustment for this discontinuity is necessary to obtain homogenous precipitation data for climate change and hydrological studies. The relation of the relative catch ratio (RCR, ratio of measurements of shielded gauge to unshielded gauge) versus wind speed and temperature has been developed for Alter and Tretyakov wind shields. Strong linear relations between measurements of shielded gauge and unshielded gauge have also been found for different precipitation types. The linear relation does not fully take into account the varying effect of wind and temperature on gauge catch. Overadjustment by the linear relation may occur at those sites with lower wind speeds, and underadjustment may occur at those stations with higher wind speeds. The RCR technique is anticipated to be more applicable in a wide range of climate conditions. The RCR technique and the linear relation have been tested at selected WMO intercomparison stations, and reasonable agreement between the adjusted amounts and the shielded gauge measurements was obtained at most of the sites. Test application of the developed methodologies to a regional or national network is therefore recommended to further evaluate their applicability in different climate conditions. Significant increase of precipitation is expected due to the adjustment particularly in high latitudes and other cold regions. This will have a meaningful impact on climate variation and change analyses. Copyright 1999 by the American Geophysical Union.

Prey deliveries per day increased as the nesting season progressed, with an average of 2.68 prey deliveries during incubation, 4.10 items during brooding, and 4.51 items during the nestling phase. The highest delivery rates were concentrated between 1-3 hours before sunrise (02:00-05:00) and 1-3 hours after sunset (18:00-21:00). Trip duration during diurnal hours increased 14 fold from incubation through the nestling phase, compared with a 7.2 fold increase during nocturnal hours. Nest boul duration decreased during both diurnal (36%) and nocturnal hours (76%) across the nesting season. Nest attentiveness decreased as the nesting season progressed, from 97% during the incubation phase to 47% during the nestling phase. Owls attended nests at higher rates during diurnal hours than nocturnal hours across all nesting phases. Activity patterns of Mexican Spotted Owls showed marked cyclical changes in response to ecological factors. Fluctuations in nesting behavior were related to changes in nesting phase and time of day.

Methods: Retrospective review of safety data from 1987 to 1995. Crashes or mishaps are categorized into three classes: A, B, and C. Class A reflects the most serious mishap and involves loss of life or aircraft destruction, whereas classes B and C represent lesser but still significant mishaps. Crash rates are compared on a year-by-year basis and are reported as events per 100,000 flight hours. Statistical analysis was performed by the z test with Yates' correction, with significance set at p less than or equal to 0.05. Conclusions: There is a very low overall incidence of crashes in both groups. There may be no practical difference between Army general and aeromedical aviation mishap rates. Furthermore, Army crash rates are comparable with published civilian mishap rates.

Historical data on deposition patterns between 1956-1985 showed that 30-y cumulative annual total (wet + dry) SO sub(4)-S concentrations were 19.9, 20.8 and 23.9 kg ha super(-1)y super(-1) and total (wet + dry) N concentrations were 5.99, 6.57 and 7.50 kg ha super(-1)y super(-1) in Illinois, Indiana and Ohio, respectively. In 1988-1989, amounts of total dry N deposition in Illinois, Indiana and Ohio were, respectively 2.71, 3.21, and 3.88 kg ha super(-1)y super(-1). Annual decay rates based on 19 months of decomposition data increased (p < 0.05) with increased N deposition and were -0.294, -0.480, and -0.720, respectively. The decay rates correlated highly with both the total N concentration in the forest floor (r super(2) = 0.869, p < 0.0001) and the amount of total dry N deposition (r super(2) = 0.999, p = 0.007). Nitrogen mineralization from the litter was highest in Ohio and lowest in Illinois. Immobilization of S and P occurred only in Illinois. Litter at both the Ohio and Indiana sites showed a net mineralization of S and P but the rates were higher in Ohio. The results of the study suggest that atmospheric N inputs can affect litter decomposition and nutrient mineralization in oak-hickory forests in the lower Midwestern United States.

The in-hospital mortality rate in D-dimer positive patients was 28.1 % as compared to 7.1 % in D-dimer negative subjects (p = 0.024). D-dimer positive patients had significantly greater frequencies of venous thromboses (21.9 % vs 4.8 %, p = 0.035). Conclusions: The D-dimer assay identifies patients at increased risk for mortality and may be a more sensitive test to determine the presence of underlying microvascular pathology in critically ill patients. A positive D-dimer at admission to the MICU is associated with an increased risk for the later development of a venous thromboembolic event (VTE).

AN - 69575677; 9927209 AB - O6-methylguanine-DNA methyltransferase (MGMT), a ubiquitous DNA repair protein, removes the mutagenic DNA adduct O6-alkylguanine, which is synthesized both endogenously and after exposure to alkylnitrosamines and alkylating antitumor drugs such as 2-chloroethyl-N-nitrosourea (CNU). The MGMT gene is highly regulated in mammalian cells and its overexpression, observed in many types of tumor cells, is often associated with cellular resistance to CNU. Dexamethasone, a synthetic glucocorticoid hormone, was found to increase MGMT expression in HeLa S3 cells, concomitant with their increased resistance to CNU. Two putative glucocorticoid responsive elements (GREs) were identified in the human MGMT (hMGMT) promoter. Transient expression of the luciferase reporter gene driven by an hMGMT promoter fragment containing these GREs was activated by dexamethasone. DNase I footprinting assays demonstrated the binding of glucocorticoid receptor to these sequences. In vitro transcription experiment showed that these DNA sequences are functional in glucocorticoid receptor signal-mediated activation of transcription. These results suggest glucocorticoid-mediated induction of the MGMT gene contributes to high level expression of MGMT.

AN - 69586467; 10029309 AB - Past work suggests that tubulin from kinetoplastid parasites may present an excellent drug target. To explore this possibility, tubulin was purified on a milligram scale from Leishmania mexicana amazonensis promastigotes by sonication, DEAE-Sepharose chromatography, and one cycle of assembly-disassembly. Purified leishmanial tubulin is recognized by commercially available anti-tubulin antibodies and displays concentration dependent assembly in vitro. The vinca site agents vinblastine, maytansine, and rhizoxin bind to leishmanial tubulin as assessed by the quenching of intrinsic tubulin fluorescence and the alteration of the proteins reactivity with the sulfhydryl-specific reagent 5,5'-dithiobis(2-nitrobenzoic acid). They also interfere with the assembly of leishmanial tubulin at low micromolar concentrations. Electrophilic compounds such as phenyl arsenoxide and 4-chloro-3,5-dinitro-alpha,alpha,alpha-trifluorotoluene (chloralin), which are of interest as traditional and experimental antiparasitic agents, respectively, inhibit the assembly of leishmanial tubulin in vitro as well. Colchicine-site agents and trifluralin, on the other hand, have little or no effect on leishmanial tubulin in these assays. Maytansine, taxol, and the electrophiles block the growth of Leishmania donovani amastigote-like forms in vitro at low ( <1 microM) concentrations, while colchicine site agents, trifluralin, vinblastine, and rhizoxin are at least two orders of magnitude less toxic to the parasite.

AN - 69553584; 9876120 AB - A continuum model is provided of the free energy terms that contribute to the molecular association of ricin A-chain (RTA) with the rRNA substrate and several small ligands. The model for RTA interactions with the RNA was taken from a previously proposed complex containing a 29-mer oligonucleotide hairpin (. Proteins 27:80-95), and models for the ligands were constructed from x-ray crystallographic structures. The calculated absolute free energies of complex formation for the RTA-RNA assembly and several single-residue substitutions are in good agreement with experimental data, given the approximations of evaluating the strain energy and conformational entropy. The free energy terms were found to resemble those of protein-protein complexes, with the net unfavorable electrostatic contribution offset by the favorable nonspecific hydrophobic effect. Decomposition of the RTA-RNA binding free energy into individual contributions revealed the electrostatic "hot" spots arising from charge-charge complementarity of the interfacial arginines with the RNA phosphate backbone. Base interactions of the GAGA loop structure dominate the hydrophobic complementarity. A linear-scaling model was parametrized for evaluating the binding of small ligands against the rRNA substrate and illustrates the free energy determinant required for designing specific RTA inhibitors.

AN - 69483476; 10813361 AB - Studies were conducted using a novel in vitro approach to investigate the efficacy of acetamidine hydrochloride (ACE) and guanidine hydrochloride (GUAN), previously shown to block gramicidin D (GRAM) channels in artificial membranes, in preventing the toxic effects of GRAM in NG108-15 (neuroblastoma x glioma hybrid) cells. Specifically, intracellular microelectrode techniques were employed to examine changes in membrane resting potential (Vm) and input resistance (Rin). At 1 micromol/L, ACE significantly reduced loss of Vm induced by 1 or 10 microg/ml GRAM, although higher concentrations of ACE did not afford enhanced antagonism. GUAN, in contrast, produced a concentration-dependent antagonism of GRAM-induced Vm and Rin loss, with high concentrations (10 or 100 micromol/L) completely preventing diminutions in both Vm and Rin. In control cells superfused without GRAM, ACE produced a direct, concentration-dependent reduction in Vm and Rin, whereas GUAN hyperpolarized NG108-15 cells but did not alter Rin.

AN - 69432290; 10668456 AB - Neuroprotective effects of HU-211 (dexanabinol), a synthetic nonpsychotropic analog of tetrahydrocannabinol, on brain damage resulting from soman-induced seizures were examined in male Sprague-Dawley rats challenged with 1.6 LD50 soman. At 5 or 40 min after onset of seizures, the rats were given an intraperitoneal injection of 25 mg/kg HU-211. All rats that received soman showed electrocorticographic (ECoG) evidence of sustained seizures and status epilepticus for 4-6 hr. HU-211 had no effect on either the strength or duration of seizure activity. Administration of HU-211 at 5 min after seizure onset reduced median lesion volume 86% (as assessed by microtubule-associated protein 2 (MAP2)-negative staining), and when administered 40 min post-onset, the reduction in necrosis was 81.5% despite the presence of continuous seizures for 4-5 hr. These observations were corroborated by hemotoxylin and eosin (H&E) histopathological assessment that showed a significant reduction in piriform cortical neuronal damage in HU-211-treated animals. It is concluded that HU-211 provides considerable neuroprotection against brain damage produced by soman-induced seizures.

AN - 69310678; 10580640 AB - Staphylococcal exotoxins, staphylococcal enterotoxins A-E (SEA-SEE), and toxic shock syndrome toxin- (TSST-1) are potent activators of the immune system and cause a variety of diseases in humans, ranging from food poisoning to shock. These toxins are called superantigens because of their ability to polyclonally activate T cells at picromolar concentrations. Superantigens bind to both MHC class II molecules and specific Vbeta regions of the T cell receptor, leading to the activation of both antigen-presenting cells and T lymphocytes. These interactions lead to excessive production of proinflammatory cytokines and T cell proliferation, causing clinical symptoms that include fever, hypotension, and shock. Recent studies suggest that staphylococcal superantigens may also be involved in the pathogenesis of arthritis and other autoimmune disorders. This review summarizes the in vitro and in vivo effects of staphylococcal enterotoxins and TSST-1, recent progress with the use of transgenic knockout mice to identify key mediators and receptors involved in superantigen-induced shock, and therapeutic agents to mitigate the toxic effects of staphylococcal superantigens.

This paper investigates biotreatment systems based on exploiting naturally occurring phenomena in the rhizosphere--the soil adjacent to and influenced by plant roots. Rhizosphere-based remediation systems would be inexpensive to implement and maintain and would be applicable to remote or permafrost sites. Herein, this paper provides the rationale for using rhizosphere-based biotreatment systems and some initial results. In both laboratory and field studies, successful plant germination, plant growth, and root intrusion into and through contaminated soil are demonstrated. Using a Captina silt loam in a 10-week laboratory study, the effects of vegetation and contamination on microbial numbers were compared. The vegetation treatments included an unvegetated control and a vegetated treatment seeded with bahiagrass (Paspalum notatum). The contamination treatments included an uncontaminated control and a treatment with 2000 mg pyrene kg (super -1) soil added. Microbial numbers at 10 weeks were not significantly influenced by the contaminant level of 2000 mg pyrene kg (super -1) soil compared to the control. However, microbial numbers were greater in the rhizosphere of the bahiagrass-vegetated soil compared to the unvegetated soil. In a 34-week field study, total petroleum hydrocarbon (TPH) concentrations of a diesel-contaminated soil decreased significantly more in the rhizosphere+nutrient treatment compared to the control that was not vegetated or fertilized. Bacterial numbers in the field study were 287 times greater in the rhizosphere+nutrient treated soils than in the control treatments. Measurable TPH compounds in the plant tissue were insignificant. The data demonstrated that rhizosphere-enhanced treatment of organic-contaminated soils can be effective in reducing soil petroleum concentrations and may be a cost-effective strategy particularly suited for treating cold-region sites where remediation options are limited by cost, remoteness of the site, and/or brevity of the treatment season.

Historically, field tests had been conducted against various obstacles and two test bores 3.5 m in diameter were excavated into granite, one of which was taken to a test depth of 17 m. A cost analysis had been performed using the experimental data collected from the program in the 1970s. Advance rates that were limited only by the estimated ability to remove muck were assumed in this analysis. These assumptions lead to boring rates that were not only more than three times faster than conventional drill and blast techniques but also considerably cheaper. The economic analysis has been recomputed with the aid of empirical cost functions from the US Bureau of Mines. It has been found that under certain circumstances the REAM technique uses less propellant per kilogram of ore produced than conventional drill and blast methods. Also, if cost is not an issue then the REAM technique can provide advance rates unobtainable by conventional methods.

Hooke suggested that erosion steepens the adverse slopes on the downglacier sides of overdeepenings until supercooling of subglacial water flow causes ice growth that plugs water channels and reduces the sediment transport needed for further steepening. Erosion then would be localized on the upglacier, headwall sides of overdeepenings, causing overdeepenings to migrate upglacier over time. We hypothesize that an increasing ice-surface slope would reduce or eliminate supercooling of water flowing from an overdeepening, allowing erosional steepening of the adverse slope. Subsequent decrease in ice-air surface slope would favor supercooling and accretion of debris-rich basal ice accompanied by sediment deposition in the overdeepening from disruption of subglacial streams. We further hypothesize that glacial erosion rates and sediment yield depend sensitively on the interactions of subglacial water with bedrock-floored and sediment-floored overdeepenings.

Application of a simple open two-component reservoir model indicates that (super 18) delta O, delta D, and (super 3) H activity for discharge are within the requisite ranges to form basal ice, and that there is a genetic relationship between the two. Additionally, the temporal variability of delta (super 18) O in the basal ice can be attributed to relative amounts of meltwater and rainfall runoff present in the subglacial discharge.

The daily positions of five (1997) to six (1996) stations anchored into the ice, were measured using total station surveying equipment. The velocity curves for each station were stacked and smoothed to generate one velocity profile for each of the two study periods. The velocity curves for each summer show a similar seasonal trend of velocity increasing abruptly and significantly in early June, attaining a seasonal high in late June and early July, then generally decreasing through mid-August. Data from both field seasons show that velocity increases after mid-August through the end of the field season. In addition, short-term, small-scale fluctuations in the two records indicate the glacier responds to meteorological events, such as sunny periods and rainfall, as illustrated by abrupt changes in velocity. The velocity records are compared to input and output proxies in an attempt to develop a conceptual model for the evolution of the subglacial drainage system throughout the melt season. The current hypothesis is that Matanuska Glacier's subglacial drainage system consists of low, broad canals in subglacial sediment. The velocity records have a hysteretic relationship with the discharge of a stream that is sourced by glacial discharge vents. At the start of the melt season, there are large increases in ice velocity with very little change in stream discharge, indicating the subglacial drainage system has not fully developed to accommodate the increasing influx of meltwater generated by the onset of summer temperatures. It is hypothesized that meltwater influx increases through late June and early July, and subglacial water storage causes increased basal water pressure. Drainage system evolution and increased basal water pressure are suggested to control the horizontal ice velocity. Late melt season ice flow reduces drainage system capacity faster than the meltwater inputs decrease. Some drainage areas may cease discharging water because subglacial pathways become disconnected, which causes storage to again increase.

The technique has yielded realistic matrix T estimates at three karst and fractured sites tested thus far (Y-12, Oak Ridge, TN, Ammunition Burning Ground, Crane, IN, and Ft. Campbell, KY). Field data show that well hydrographs are valid indicators of the T of matrix portions of karst or fractured aquifers. Results show T values to be in good agreement with values calculated using more traditional parameter estimation techniques such as aquifer pumping tests and slug tests in matrix dominated wells. In addition, the technique allows estimation of separate Sy in different domains of the aquifer: conduit/larger fractures, smaller fractures, and aquifer matrix. In the case of the sites evaluated, the Sy calculated for the larger fractures was one to two orders of magnitude smaller than that in the matrix portions of the system. The well hydrograph analysis technique shows promise for obtaining reliable estimates of aquifer matrix T and Sy in multi-porosity systems with a simple, relatively inexpensive, and passive method. Thus far, the utility of the technique is limited in its application to shallow, submerged, interconnected, multi-porosity systems located in areas with sufficient rainfall for water levels in wells to respond to precipitation events. Use of this technique in combination with (1) traditional tracer test results to obtain flow velocities in quick flow portions of the aquifer, (2) slug tests in quick-flow dominated portions of the aquifer to estimate T of the conduit/fracture zones, and (3) estimates of the percentage of the aquifer to which to apply the differing Sy values will allow improved characterization of hydrologic parameters in heterogeneous, multiple porosity systems.

Because of their hydrophobicity, PAHs accumulate in bed sediments and pose a risk to the benthos. Information on the toxicity of sediment-associated PAHs is, however, limited and more information is needed to improve sediment quality-criteria and ecological risk analysis. This research project was designed to improve our understanding of the acute and sublethal effects of PAHs to benthic invertebrates. Sublethal bioassay protocols for benthic harpacticoid copepods were developed, and two species of harpacticoids were exposed to a range of concentrations of sediment-amended PAHs; the single compounds fluoranthene and phenanthrene as well as a complex mixture (diesel fuel). The harpacticoid copepods Schizopera knabeni and Nitocra lacustris were tested using several bioassay approaches. Reproductive assays, feeding assays and avoidance tests were conducted in addition to lethal tests for S. knabeni. Test protocols yielded repeatable results and statistically sound data. Adult harpacticoids were found to be relatively tolerant to PAHs in 10-day exposures (e.g., the LC (sub 50) for S. knabeni was 345 mu g/g PAH). Species-specific differences in sensitivity were detected. Early life history stages were much more sensitive than adults in one species but not in the other. Concentrations of PAH as low as 26 mu g/g PAH decreased copepod offspring production, egg hatching success, and embryonic and early-stage development, demonstrating the high sensitivity of life history-related endpoints. In addition, grazing on microalgae was significantly impaired at concentrations as low as 20 mu g/g PAH after short exposures ( or =2.5 km cross-shore. The morphodynamic activity on the shoreface is sub-divided into three types; i) inactive shoreface (no morphodynamic activity is observed seaward of the shoreward depth of closure (at 5 to 8 m water depth)); ii) partially active shoreface ("re-opening" of the shoreface profile i.e. the profile must first exhibit a shoreward closure); and iii) fully active shoreface (the profile does not exhibit a shoreward closure and so is morphodynamically active along the total cross-shore distance). At Large-Scales (> or =10 years; > or =10 km alongshore) it is found that the percentage occurrence of type ii) increases rapidly with time until 20 years when an almost constant value is reached. Simultaneously the percentage occurrence of type iii) increases linearly with time so that, after 32 years 33% of profiles are fully active on the shoreface. It is hypothesised that shoreface activity results from slow, cumulative rather than occasional, extreme processes. Extrapolation beyond the data limits suggest that after approximately 90 years, all profiles along the Holland coast will exhibit morphodynamically active shorefaces. This work verifies that the middle/lower shoreface is morphodynamically active at decadal scales. These changes are occurring at timescales which mean that they must be considered within coastal management. Further, these results suggest that the onshore feed of sediment from the shoreface will have profound implications for long-term sediment budgets (cf. Stive et al., 1990).

The model was run over an initially plane sloping bed (1:50); the wave climate was schematized into a storm period of 11 days (wave height H (sub s) approximately 2-3 m), followed by a fair-weather period of 40 days (H (sub s) approximately 1 m). The tidal range TR was varied between 0 and 8 m. The model predicted the formation of a subtidal multiple bar system for TR4 m) an intertidal ridge-and runnel-like system was formed with similar bar spacing, but smaller bar heights than modeled for the subtidal bar systems under non- to mesotidal conditions (TR<4 m). The predicted bar characteristics agree reasonably well (at least, qualitatively) with those observed under natural conditions. JF - Coastal Sediments: Proceedings of the ...

One method was based on topographic surveys where the ground level was repeatedly measured at on-offshore fixed points on the beach face. The other method involved direct measurements through a streamer-type sand trap. The on-offshore sediment transport rates obtained by using these two methods agreed well with each other. Based on results from the observations in this study and previous observations conducted by the authors (Kubota, et al.; 1997), the relationship between the on-offshore sediment transport rate on the beach face and the external forces that produced the transport was investigated. The on-offshore sediment transport rate on the beach face was shown to be closely related to a parameter involving the deviation of the beach face slope from its equilibrium value and the swash oscillation height and period.

By testing different surge levels and duration, effects of these to the shoreline change were evaluated. In addition, the conditions of beach recovery were investigated experimentally. On the other hand, we proposed the method, which can be applicable to complex hydrograph such as real storm surge by modifying equation proposed by Kriebel and Dean. Moreover, applicability of this method is verified by comparing computing result with experiments. JF - Coastal Sediments: Proceedings of the ...

This paper presents the data collected during the part of the measurement programme with a bed consisting of sand. During the latter series, detailed measurements of instantaneous fluid velocities and sediment concentrations were made resolving the spatial structure (in both horizontal and vertical direction) of the velocity and concentration fields. The analysis and interpretation is aimed at identifying the relative importance of mean flow, long and short waves to the net sediment fluxes and transport. It is found that the oscillatory suspended sediment transport dominated by the short wave transport cannot be neglected. Secondly, attention is paid to the sediment response and its effect on the sediment fluxes. The net oscillatory fluxes are seen to critically depend on the phase shifts between velocity and concentration at each frequency. JF - Coastal Sediments: Proceedings of the ...

Prior to harbor construction (1877/79 to 1948), net shoreline advance occurred throughout much of the study area. After the Harbor was constructed, there was down-drift recession along a reach extending to about 2.1 km south of the Harbor (1948 to 1970). For the same period, the 8.3-km of coast south of this erosion zone illustrated net accretion. As a result of beach fill placement in 1974/75, net shoreline advance was documented for the period 1970 to 1996 for a distance 8.8 km south of the entrance, indicating long-term effectiveness of the beach fill. Regional changes in sand volume along the updrift margin of the north Harbor jetty were quantified by analysis of historical bathymetric data for the years 1929, 1956, and 1996, coupled with shoreline-position data for 1928, 1948, and 1996. Bathymetric surfaces were generated for each time period to calculate net volume changes by comparing surfaces. These data, combined with dredging records, defined the net longshore sand transport rate at Canaveral Harbor (236,000 m (super 3) /yr) for determining a net bypassing rate in the absence of the Harbor (119,000 m (super 3) /yr).

Different epsilon (sub s) -distributions are selected and optimized for a set of measurements with currents and waves. The best performing method is used to analyze the dataset. This results in plots of the bottom concentration, c (sub 0) , the maximum value of the sediment diffusion coefficient coefficient, epsilon (sub s) and the value over which epsilon (sub s) is constant, a, for different hydraulic conditions. The consistency of these parameters is quite good. Further, it is shown that very large differences are found if an epsilon (sub s) -distribution is used to calculate the concentration profile for both uniform and graded sediment.

AN - 52289440; 2001-001478 AB - A summary is presented of the results of an inlet management study to determine the alongshore impacts and sediment budget of Pensacola Pass, FL, U.S.A. Pensacola Pass is a large tidal entrance on the Gulf of Mexico, located in Escambia County in the westernmost portion of Florida, and has existed in this area for over 300 yrs. Maintenance and new work dredging of the entrance since 1883 have increased the controlling depth of the channel from approximately 6.5 m to over 12 m. The channel dredging has resulted in the removal of over 35 million m (super 3) of material, of which approximately 21 million m (super 3) were disposed of offshore. The dredging program has drawn down the ebb-shoal volume of the Pass and significantly reduced natural sand bypassing. Comparison of limited pre-dredging data suggest the dredging and the construction of two small structures on Perdido Key (west side) have arrested the westward migration of Santa Rosa Island (east side). Analysis of historic shoreline changes, even-odd analysis, and wave refraction/littoral transport data indicates that the Pass noticeably influences the adjacent shorelines along a reach of 12 to 15 km, to either side. Wave refraction analysis indicates the possibility of a local reversal in net transport direction from westerly to easterly drift along Perdido Key, drawing sand off the downdrift shoreline back into the Pass. Sediment budget analysis employing a new technique proposed for the upcoming Coastal Engineering Manual confirms this phenomenon and indicates an ambient net transport value for the area of 30,000 to 55,000 m (super 3) /yr, westerly directed.

Three separate tests were conducted, one with a constant water level and two with a sinusoidal variation in water level--each with the same tidal period but with different amplitudes. The identical (irregular) wave characteristics were used for all three tests. Our results indicate that water level fluctuations over time scales associated with tides have significant impact on beach profile development, particularly in the horizontal location of the bar and berm features. This impact was greatest for the largest tidal amplitude. JF - Coastal Sediments: Proceedings of the ...

The budget analysis was carried out for 11 sectors which were further subdivided into a total of 91 subreaches, depending on shoreline type, orientation and exposure; offshore bathymetry and substrate type; and the existence of coastal structures. Physical data including wind, waves, currents, water levels, beach profiles and nearshore bathymetric and bottom geophysical surveys were measured and/or hindcast to support the sediment budget development. Selected numerical model investigations were also conducted to provide insight into shoreline behavior and sediment transport rates. Where possible the measured entrapment of sediment at a number of coastal structures, including a temporary sand bag structure installed for this investigation, was employed to verify sediment transport rates in the sediment budget. The dominant source of sediment on the southwest coast is a pair of large offshore reefs. Waves generated by the tradewinds drive sediment to the west along the southwest coast at an average potential transport rate in the order of 175,000 cubic meters per year. However, the actual rate is about a third of this rate because transport occurs primarily along the beach face and pathways on the nearshore reef. Along the more protected west coast sediment transport is generally along the beach face and to the south at net rates that are about a tenth of the rate on the southwest coast. A sediment source for the west coast is the many fringing reefs that lie along the shoreline. JF - Coastal Sediments: Proceedings of the ...

The distinct scales of resuspension for sand and mud at this location allow concentrations of both size classes to be determined simultaneously from a single OBS time series. For this study, OBSs were calibrated separately using sand and mud collected off Duck, N.C., OBS voltage gain associated with mud was found to be an order of magnitude larger than that for sand. Based on this calibration, it was shown that the mass concentrations of particles smaller than 63 microns pumped off Duck during October 1997 were consistent with the lowest 1st to 5th percentile of voltage recorded by the OBSs. Calibrated OBS response above this background turbidity was consistent with pumped sand concentration as long as corrections were made for (i) varying size of suspended sand, (ii) the precise time of pump sampling and (iii) for apparent noise in the OBS records. Correction for the smaller size of suspended sand relative to that used during calibration decreased OBS estimates of sand concentration by about 50%. Accounting for noise decreased OBS estimates of sand concentration by about 0.04 and 0.2 grams/liter during the first and second parts of the field experiment, respectively. This study also demonstrates that suspended sand and mud can be accurately pump sampled in the nearshore during storms using relatively inexpensive, commercially available equipment.

Muriwai is a high-energy meso-tidal beach characterised by modal breaker heights of 2.5 m and incident wave periods of 10-15 s. The monitored rip system had a 400 m long, 75 m wide longshore feeder channel and a 150 m wide rip-neck channel oriented obliquely to shore, extending seaward over a distance of almost 400 m. During the experiment, the beach evolved from a longshore bar-trough and rip state to an incipient transverse bar and rip configuration. Mean eulerian flow velocities measured on the margin of the feeder channel and rip-neck were on the order of 1 ms (super -1) and instantaneous flows were commonly in excess of 2 ms (super -1) . Mean lagrangian surface flow velocities extending from the base of the feeder through to the rip-head were on the order of 0.7 ms (super -1) with maximums in the rip-neck region of 1.6 ms (super -1) . A distinct tidal modulation of rip current flow existed with maximum velocities occurring at low tide and minimum velocities at high tide. Although the magnitude of the morphodynamic and hydrodynamic processes occurring within large-scale rip systems is extreme, the behaviour of these rip systems is very similar to low-energy rips with much smaller spatial scales. There is evidence to suggest that distinct morphodynamic scaling relationships transcend these two energy regimes. JF - Coastal Sediments: Proceedings of the ...

From wave tunnel measurements it appeared that the near-bed transport rate could be predicted with reasonable accuracy using a relatively simple bedload transport formulation. Suspended load transport rates (q (sub suspended) ) were measured in a large wave flume and in the field using optical and acoustical instruments. The time-averaged suspended transport component and the high-frequency suspended transport component were found to be the most important components in determining the direction and the magnitude of the net suspended transport rate. The computed near-bed transport rate was found to be of the same order of magnitude as the net suspended transport rate and sometimes even larger. The high-frequency suspended transport component could be predicted with reasonable accuracy using the method of Houwman and Ruessink (1996). JF - Coastal Sediments: Proceedings of the ...

These measurements revealed cross-shore variations in the heavy-mineral concentration. To determine which mechanisms generate these variations in sediment density and what the effects of these placers are on sediment transport and profile deformation, laboratory experiments are conducted. These experiments comprise measurements of hydrodynamics, profile deformation, suspended sediment concentrations and sediment composition under storm conditions on a 1:40 sloping bed with varying sediment composition.

A computational model of the flow and sediment transport over vortex ripples has been constructed, which makes it possible to perform morphological calculation of vortex ripples. Using a stability analysis of the fully developed ripples, the minimal wave length of the ripples is calculated. This minimal wave length was found to depend on the settling velocity only.

Investigations of shoreline erosion, therefore, necessarily include a range in scales of processes and causes, both spatial and temporal. This is illustrated by the review of a number of case studies of erosion problems throughout the world. The examples show that too often we adopt an overly simplistic view of the causes of erosion, generally focusing on the short-term factors, the most recent storm, while ignoring the longer-term underlying causes. The latter are commonly the product of human impacts on the environment. We think of humans as being the victims of coastal erosion--we overlook the fact that often they are the cause.

However, little quantitative verification of the standard functional shoreline forms, the logarithmic-spiral shape and parabolic shape, has been made. In addition, limited guidance is available for applying the functional shapes in engineering practice. In this paper, we investigate the two shapes by fitting to 46 beaches in Spain and in the North America covering from large regional scale to small project scale. Software is described which automates the fitting. A new function, called the hyperbolic-tangent shape, is introduced for engineering applications. The hyperbolic-tangent shape is easy to fit, and its controlling parameters have simple geometric interpretation. Guidance is given for interpreting and fitting the three headland-bay beach functions, with background data listed. JF - Coastal Sediments: Proceedings of the ...

The purpose to this paper is to describe time-tested procedures used to design stable protective beach planforms with headland breakwaters and beach nourishment that interface the system both alongshore with adjacent properties and upland with the client's landuse objectives as well as address concerns of environmental regulations. Therefore, system design must include not only wave climate and littoral process analyses but also upland runoff, bank geology, shoreline morphology, sedimentation, aesthetics and function. The three sites in this paper reflect additions and refinements to design procedures resulting from involvement by the authors in over 60 previous Chesapeake Bay installations of headland breakwaters since 1985. Design procedures for each site include: 1) a shoreline history and geomorphic assessment, 2) wind/wave hindcasting, 3) nearshore wave refraction modeling with RCPWAVE and 4) beach planform modeling using empirical formulae. Over the past ten years the authors have developed and calibrated the elements of the above design procedures with a high degree of confidence. JF - Coastal Sediments: Proceedings of the ...

The quantification of the suspended sediment transport especially inside the surf zone is extremely difficult caused by the spatial complexity and temporal variability of hydro- and morphodynamic processes. Therefore field and laboratory data are needed to describe and quantify sediment transport according to hydraulic conditions. Within the EU-MAST III SAFE-Project prototype scale wave flume experiments have been carried out in 1996 and 1997 in the "Grosser Wellenkanal" (GWK) in Hannover. The experiments focussed on the development of beach profiles under random waves attack and varying sea levels. The analysis of experimental hydro- and morphodynamic data emphasize the importance of a precise description of the suspended sediment distribution along the profile with respect to engineering use. In this paper results of the suspended sediment distribution in cross-shore direction obtained from the SAFE-experiments are presented. JF - Coastal Sediments: Proceedings of the ...

Ensemble averaging of nearly identical repeated wave groups allowed us to examine the influence of the wave group, particularly the effects of antecedent waves, on the patters of re-suspension at an intra-group time scale with a greater degree of confidence in SSC estimates than is conventionally possible. Systematic, vertical migration of inflection points in wave averaged SSC profiles and hysteresis in wave averaged near bed SSC measurements both illustrate the importance of antecedent wave suspension.

The increasing availability of more reliable long-term observational data (direct and indirect) and of more detailed shoreface field observations seems to support earlier suggestions that the shoreface may be a potential source of coarser sediments to the nearshore. Here, this process is investigated by hindcasting and extrapolating long- and short-term observations available for the shoreface along the Ebro Delta. Analysis of the field data indicates that a structural onshore sediment flux is likely. Although a direct proof that this is also true on longer-term scales is not easy to substantiate, the careful conclusion is drawn that there exists circumstantial evidence that there is a net long-term feeding of coarser sediment towards the nearshore to an amount which is just about enough to compensate for "losses" due to the present sea-level rise rate in the region.

The technique was developed in the Davidson Laboratory large wave tank, which measures 98 m by 3.7 m by 1.8 m deep. The tank is equipped with a programmable hydraulic wavemaker and a 20-m long sand beach (median grain size, 0.23 mm). Monochrome photographs were obtained using a Hasselblad 500EL camera housed in a clear glass enclosure fixed above the sand bed in 20-cm deep water. Grab samples containing water and suspended sediments were taken from the tank at discrete elevations above the bed at the exact moment a photograph was taken. The developed photographs were digitized and saved as TIFF files. Gray Scale (light intensity) measurements were made from the images in the vicinity of the water/sand samples. The gray scale readings from the images were correlated with the sediment concentration from the grab samples in order to calibrate the photographs. JF - Coastal Sediments: Proceedings of the ...

It may be hypothesized that stochastic turbulent processes in a near bed zone control deposition of flocs. So far, many studies have been performed for unidirectional currents. However, a large difference exists in basic characteristics for the response of water-mud system to wave-induced motion. In this paper, a physical model is studied for deposition of natural cohesive sediments under regular waves. Measuring velocities and dynamic pressure on the bottom, bottom shear stress could be estimated. It is found that at very close values of bottom shear stress the rate of deposition is rapidly changed due to pressure steepness on the bottom. The common empirical formula of cohesive sediment deposition (Krone, 1962), which depends only on bed-shear stress is modified to reflect this effect and shows a better adaptation to measured data.

It is found that at least two published relations provide good estimates of the combined wave-current bed shear stress T (sub b,cw) . Vertical eddy diffusivity epsilon (sub s) and the bed reference concentration C (sub b) are however less well quantified by existing relations. This is particularly apparent in the surf zone, where a turbulence closure model is required to accurately simulate vertical mixing throughout the depth.

The major ports are Laem Chabang, and Map Ta Put Ports which are located in a small and large bays. Both ports are located in a dynamic equilibrium bay shape. In order to control coastal erosion, an extended breakwater and a new coastal structure were proposed as an upcoast control point. A static equilibrium bay can then be formed and the problem of coastal erosion can be minimized.

This study presents theoretical models of instability of river mouth locations in pocket beaches. The theory shows that river mouths cannot exist stably in the central region of beaches but can exist only within regions near the both ends of beaches when the capability of longshore sediment transport relative to the dimensions of beaches is not sufficiently large in comparison with the load of river sediment supply relative to the dimensions of rivers.

Whilst they are characterised by cellular circulation often accompanied by intermediate beach and shore zone morphology, the dimensions of rip systems can vary by an order of magnitude. Small rips with longshore spacings on the order of 50-100 m are found in lower energy, short fetch sea environments, while high-energy swell environments can have rips up to 800 m apart. Despite this wide range in scale, field evidence suggests that rips across this range have very similar morphological characteristics. This paper examines the spatial and morphological characteristics of rips from a range of wave environments and identifies a systematic variation in longshore rip spacing, which can be related to the level of wave energy associated with the regional wave environments.

Recent technologies such as airborne lidar provides the ability to collect coastal survey data on a regional level, demonstrating a systems approach to sediment management in the coastal region. Since becoming available, airborne lidar (SHOALS) has performed numerous coastal surveys which demonstrates the concept of this new technology towards regionalized sediment management. Recognizing the need for regional sediment management, the State of Florida and U.S. Army Corps of Engineers have embarked on adopting a systems approach toward sediment management. The objective of this paper is to describe the airborne lidar capabilities and identify the concept of using this technology towards coastal project sediment management on a regional scale.

To evaluate survey data used to calculate event-dependent D (sub c) and to extend observations to 13 m depth on an oceanic wave-dominated beach, downward-looking sonar altimeters at 3 depths (5.5, 8, and 13 m) were deployed at the Field Research Facility of the US Army Corps of Engineers. Sonar data are compared with survey data during August-December 1995. Surveyed profile data and sonar altimetry measurements of seabed elevations were within 8+ or -4 cm in 5.5 and 8 m depths. Continuous sonar altimeter measurements include storm events and span a range of seabed elevations of O: 40 cm at all locations. JF - Coastal Sediments: Proceedings of the ...

The contribution of mean currents and oscillatory motions were estimated for both longshore and cross-shore fluxes. Most of the transport can be explained by the mean component, specially during fair-weather periods, major deviations occur during the impact of storms where the wave contribution increases in importance. Moreover, when analyzing the vertical distribution, a consistent behaviour has been observed, in such a way that all measured levels contribute in the same direction. However, during a major storm some reversals where detected and has been explained by the presence of strong winds which induce a mean current in the upper layer directed seawards whereas at the bottom is directed onshore and mainly explained by wave action. Depth-integrated cross-shore and longshore transports are of the same order of magnitude. Cross-shore fluxes are shoreward during all the measured period whereas the longshore component suffers some reversals, the major in coincidence with the pass of a sever storm, although a southern trend dominates.

An 82-km-long beach fill on the northern New Jersey coast is influenced by a regional gradient in longshore sand transport and has a 0.8-km-long "hot spot" of accelerated erosion at Monmouth Beach, New Jersey. This study identified the physical processes contributing to the hot spot and developed a shore-protection measure that would best maintain a 23-m wide protective berm at the hot spot over the 6-year renourishment interval, while mitigating erosion of the down-drift beach. Empirical analysis of an adjacent groin field guided the development of design alternatives, and a methodology defining the frequency of design objective violations was incorporated into the analysis and recommendations, including variability of the wave climate.

The sand was part of approximately 20,000 yds (super 3) of material emplaced from construction excavations. Mean grain-size was about 0.20 mm and approximately 18% of the sediments had diameters less than 0.075 mm. The disposal sands were eroded, then advected by longshore currents (v>0.50 ms (super -1) ), forming plume of suspended sediments. The purpose of this project was to monitor the suspended sediment concentrations (SSC) in the plume, the dynamics of the plume, and potential sedimentological and geomorphological implications of the disposal project. Grain size and beach profile characteristics indicated minimal physical change from the project. Water samples showed maximum SSC of about 1.5 gm l (super -1) adjacent the disposal site, minimum SSC in the plume of about 0.1 gm l (super -1) , and ambient SSC (outside the plume) of about 0.1 gm l (super -1) . The magnitude of nearshore water motion was sufficient to generate turbulent velocities that were large relative to fine-sediment settling velocities, and minimal deposition should have occurred in, or near, the surf zone. The plume was detected over a distance exceeding 17 km, with a width of 300+ meters. Fine sediments were dispersed over a large area, minimizing potential effects, especially vis-a-vis the production of significant deposits in the nearshore. Maximum concentrations detected were small relative to storm runoff-induced plumes common to the region. The geomorphological impacts of this project were trivial.

The data show the details, including shoal feature movements and channel migrations, of the response to channel dredging in 1997. The way the newly dredged channel is migrating is particularly interesting. The channel is beginning to migrate along its middle portion where the adjacent shoal depths are the shallowest.

Turbidity-tank tests show that, for the optical backscatter sensor, simply ignoring the light backscattered from any sand that is also in suspension results in only a small error in estimate of suspended-silt concentration. The converse is true for the acoustic backscatter sensor: ignoring the sound backscattered from any silt that is also in suspension results in a good estimate of suspended-sand concentration. Measurements from an estuarine tidal channel that is a known conduit for suspended silt and sand are used to confirm the implication from the tank tests that optical and acoustic sensors can be used to discriminate between silt and sand components of the suspended-sediment load. Whereas the optical data imply vertically uniform concentration profiles, which is consistent with vanishingly small particle settling velocity (i.e., silt), the acoustic data are consistent with an equilibrium suspension and particle settling velocity that corresponds to sand. The acoustic signal varied on an approximate 6-h cycle, exactly in phase with the tidal-current speed, but the optical signal varied on a cycle twice that length, in phase with the water depth. The differences are explainable in terms of the differences between suspended-silt transport, which is linked to waves on the surrounding intertidal flats, and suspended-sand transport, which derives from resuspension by the tidal currents of the channel-bed sediment. We conclude that, with some qualifications, the acoustic backscatter sensor can be used as a suspended-sand meter and optical backscatter sensors can be used as suspended-silt meters.

A time-varying record of the swash event covering the full swash extent at a spatial resolution of 2 mm is used to compare observed measurements to those predicted using the Shen and Meyer (1963) model for uprush following bore collapse show significant over-prediction of the maximum shoreline position, swash period and swash height. This is consistent with the findings of Hughes (1992). Observations of the video record suggest that turbulent flow continues within much of the uprush and backwash phases of the swash. A "flow reversal" phase similar to that seen by Larson and Sunamura (1993) was also observed. JF - Coastal Sediments: Proceedings of the ...

Several features are highlighted which may have implications for swash zone sediment transport models. (1) The velocity profile is not symmetrical and takes on a saw-toothed appearance in the uprush, with the rise to maximum velocity being almost instantaneous. (2) Uprush is characterized by decelerating flows and backwash by accelerating flows. (3) Exfiltration or ground water outflow induced by large negative (upward acting) hydraulic gradients, is an erosional mechanism for providing readily entrainable (fluidized) material that can be carried offshore or onshore by the flow. (4) Phasing of the destabilizing gradients with the velocity profile is essential for erosion to occur. (5) Infiltration or drainage into the bed occurs when the subsurface layers experience positive (downward acting) pressure gradients. (6) The onset of infiltration is governed by the time interval between each swash event, location in the swash lens, the subsurface flow regime and the saturation characteristics of the bed. From the data shown, it is not clear what mechanisms are responsible for beach accretion. The key to understanding accretionary events may be hidden in the complex internal mechanisms of the subsurface layer or phreatic surface which, at the leading edge of the swash limit, fluctuates between saturated and partially saturated states.

Model simulations show that skewness plays an important role in the determination of the net cross-shore sediment transport. Comparisons with laboratory data indicate that cnoidal wave theory can reproduce the observed skewness and sediment transport fairly well outside the surf zone. After wave breaking the agreement between the models and the measurements is poor. Alternative wave theories show better agreement. The phase resolving model is able to reproduce the velocity skewness well across the entire cross-shore profile. The calculated sediment transport shows better agreement than the phase-averaged model. However, discrepancies still occur in the outer surf zone. JF - Coastal Sediments: Proceedings of the ...

This has been done under conditions of wave-induced oscillatory flow. A two-channel Laser Doppler Anemometry (LDA) system was used to obtain velocity measurements over a physical model of two-dimensional sand ripples in a wave flume. The development of the boundary layer with phase can be observed clearly from velocity profiles and has been used in the calculation of bed roughness parameters.

Approximate volume balance between updrift accumulation and downdrift erosion, which served as a reliability indicator, was obtained in four of the six runs. Magnitudes of three of the four reliably measured transport rates were considerably lower than predictions by the CERC formula calculated based on contemporaneous measurements of the breaking waves. Predictions of the Kamphuis-91 formula were closer to the measured rates. Error analysis indicated that maximum uncertainties in determination of the longshore wave-energy flux factor and in the measured rate of volume change were 22 to 48% and 22 to 43%, respectively. The sum of these produced a 40 to 90% maximum uncertainty in the empirical coefficient K appearing in the CERC formula. Because the range in values of K cannot be explained by measurement error or uncertainty, it is concluded that K is not a constant and other factors must enter, such as breaker type, turbulence intensity, and threshold for transport.

Each campaign covered two complete tidal cycles (25 hours) with hourly measurements of currents, salinity, suspended sediment concentration and water level. The results show that the Camboriu estuary is a partially mixed one. During neap tide is verified a regular stratification pattern and at during spring tide it presents a intratidal variation of the salinity stratification. The suspended sediment contribution of the Camboriu estuary to the ocean during the measured conditions was of 11,900 kg during mean tide and 32,400 kg during spring tide. Resuspension is a key process in suspended sediment dynamics in this estuary, increasing the mean concentration of suspension in water column, and the fluvial advection and the vertical shear are the main transport mechanisms acting.

The reference concentration, C (sub 0) , during the storm increased rapidly for the first 20 hours but then remained approximately constant although wave heights continued to increase (for a further 30 hours). The time at which C (sub 0) stopped increasing corresponded to the beginning of the reconfiguration of the sea bed suggesting that the bed form (orbital megaripples) changes may acting to reduce the suspension process. If generally true, then the suspension (and transport?) over sea beds in equilibrium with the waves (the orbital ripple condition) maybe be significantly less than that over non-equilibrium ripples, under the same wave conditions. The suspension profiles over the bedforms were also observed to depend on the position of measurement, with the higher concentration associated with the ripple troughs.

Under the particular conditions of the experiments, the data indicate that the effect of increasing the oscillatory velocity was to increase the prominence of near bed suspension events generated during "backward" flow reversals in the wave cycle while decreasing the wave period greatly reduces the peaks associated with flow maxima. The events near "backward" flow reversals exhibit a lag with increasing elevation above the bed. This lag decreases with increasing peak oscillatory velocity.

AN - 52285359; 2001-000540 AB - The authorized Presque Isle Shoreline Erosion Control Project in Lake Erie at Erie, PA was constructed October 1989-November 1992 and consisted of a 58 segment detached breakwater system with beachfill. During construction, GENESIS modeling was used to evaluate deferring construction of the first three breakwaters. The GENESIS predicted shoreline response is compared to the actual response. Aerial photography and high-density lidar survey data (via SHOALS) were used to evaluate post-construction interactions between the nearshore, shoreline, and the breakwaters. The nearshore morphology throughout the project is highly variable and complex and a strong influence on the resultant shore response to the breakwaters.

Recent evidence from the cuspate foreland setting of North Carolina indicates that Pre-Holocene lithofacies outcrop well above closure depth across much of the shoreface. In addition, new findings from two of the cape-associated shoals, Lookout Shoal and Diamond Shoal, confirm that these features are principal sinks for sediment from the barrier island littoral system. These results are integrated into a steady-state model that estimates the long-term (past 4 ky) and large-scale sediment budget of the transgressing barrier islands and inner-shelf. Conservative estimates of the volume of sand captured within the cape-associated shoals and dispersed across the shelf imply that an additional supply of "primary-source" sand was necessary to maintain the islands through migration while accounting for the shelf deposits. Model results also reveal that the volume of sand lost from the barriers is of the same order of magnitude as the estimated contribution of sand from Pre-Holocene substrates. This near balance in volume between a primary source and its sink suggests that the amount of sand retained within these migrating islands is limited by the dominance of longshore transport and, ultimately, loss to the cape-associated shoals.

The barrier is bordered by modified inlets that have impacted the island's sediment budget. Downdrift of Masonboro Inlet that forms the barrier's northern border, chronic erosion and overwash have precluded dune redevelopment. The Hurricanes of 1996, coupled with the aforementioned factors, have led to rapid translation of major barrier segments. Hurricane Fran one of two hurricanes to impact the island during a seven-week period in 1996 produced surge levels that exceeded the 100-yr flood level (3.4 m). Recession varied from less than 12 m along the inlet fillet to more than 45 m along the reach updrift of Carolina Beach Inlet, which forms the southern boundary of the island. Post-storm profile elevations along the southern half of the island were less than 1.5 m above mean low water (MLW). The southern portion of the island was translated landward during Hurricane Fran. Shoreline recovery was monitored during the past 18 months at eight stations along the barrier. The data show dramatic variations in shoreline recovery patterns. The net shoreline (HWL) change varied from +40 m along the northern segment to -8 m along the southern segment where overtopping routinely occurs. Much of the barrier's southern portion will be translated landward at accelerated rates due to the lowered profile and increased washover activity. JF - Coastal Sediments: Proceedings of the ...

Most of the beach profile models developed, neglect the effect of long waves. In this study the effect of long waves on the cross-shore sediment transport rates is investigated using a numerical model. The model combines a phase-resolving wave height module based on the Boussinesq equations, with an intra-wave sediment transport module. The wave module is shown to predict the intra-wave currents well for both the short and long wave components. The sediment transport calculations showed that the long waves have only a small effect on the time averaged sediment transport rates. The long waves were found to have a larger effect on the instantaneous sediment transport rates. JF - Coastal Sediments: Proceedings of the ...

The vertical profiles of suspended sediments were measured acoustically, and the vertical coherence length scale was found to be an order of magnitude greater than the wave boundary layer. The cross-shore horizontal coherence length scale of suspended sediment was determined using a two meter lagged array of six optical backscatter sensors. The horizontal coherence length scale, defined as the e-folding scale of the exponentially decreasing horizontal coherence, was approximately 0.8 times the rms wave orbital excursion length for all cross-shore stations. Both the vertical and horizontal coherence length scales are longest for infragravity waves and decrease with increasing frequency. JF - Coastal Sediments: Proceedings of the ...

In this paper, we analyzed the observed field data to determine the relationship between wave conditions and the fluidization of the sand and also the movement of the sand in the surf zone, especially near the breaking points where sediment transport is dominant. The following results were obtained: (1) The change in the water depth, estimated from the effective stress at the time of data collection, correlates with the daily sounding data. (2) The depth estimate oscillates diurnally and the oscillation appears to correspond to the rise and fall of the sea surface associated with the tide. (3) In the surf zone, the effective stress change is caused not only by steep waves but also by the action of the wave breaking itself. Strong offshore currents are triggered by the breaking of a series of steep waves. (4) There is a difference between the long-term current pattern at the offshore side of the bar and that at the onshore side. This difference seems to contribute to the formation of the bar.

A quantitative representation of that uncertainty can be used by regulators to implement different degrees of protection for areas with different degrees of certainty. Uncertainty analysis was performed for delineation of one- and five-year WHPAs for two municipal wells within a buried-valley glacial-outwash aquifer in southwestern Ohio. An approximation of the three-point Gauss-Hermite quadrature formula was used. This method is an alternative to simple Monte Carlo random sampling, typically requiring fewer model runs. The method results in expected values and variances of model predictions and quantifies parameter main and two-way interactive effects. This study explored the collective impact of the uncertainties associated with six model parameters. Parameter probability density functions (PDFs) were based on field data and modified using a groundwater flow model to ensure that all combinations of parameter values, within their PDFs, yielded an acceptable model calibration. The one-year WHPA for the upgradient well had a high degree of associated uncertainty represented by the difference in size between the WHPA low and high 95% confidence interval limits. The large uncertainty was due to the uncertainties associated with model parameter values, especially effective porosity and horizontal hydraulic conductivity. River conductance also had a substantial impact on the WHPA predictions. The WHPAs for the downgradient-well and the five-year WHPA for the upgradient-well were limited by upgradient hydrogeologic boundaries; their prediction was, therefore, less sensitive to the uncertainties inherent in the model parameters.

An analysis and geometric characterization of these morphologic shoreline features revealed that the magnitude of the shoreline undulations approximates typical protective berm design widths and exceeds typical advance nourishment beach widths. Because shoreline undulations are natural morphologic features of the Fire Island shoreline their presence after project construction must be anticipated. Conclusions drawn from the analysis of the Fire Island shoreline undulations indicate that the design berm width could be compromised well before scheduled renourishment if explicit consideration of shoreline undulations is not included in the development of the design cross-section.

To implement this economically beneficial practice, guidance is required concerning the behavior of submerged mounds and bars. Storm recovery and onshore migration of sand bars involve similar sand transport processes that must be understood in order to correctly predict onshore movement of these nearshore berm-type features. Many numerical models of nearshore profile change adequately model offshore sand transport and associated profile change, but generally lack the capability of predicting shoreward migration of bars and profile recovery. The problem, in part, is the small number of well documented cases of physical processes involved in shoreward bar migration. Following a storm in October 1997, extensive transport process measurements were made at the US Army Corps of Engineers Field Research Facility during a period of shoreward bar migration and reattachment of the bar to the beachface. Measured rates of nearshore profile change were compared to rates inferred from gradients in measured cross-shore transport. Direction of bar migration was also distinguished by wave asymmetry and undertow. JF - Coastal Sediments: Proceedings of the ...

To date, over 2,000 profiles have been collected from Coney Island to Montauk Point during eight sampling cycles. Overall, the geomorphology of the south shore beaches reflects the fact that wave energy increases toward the east end of Long Island. For example, sand bars are deeper, further offshore, and contain more sand in the east than in the west. Short-term depth of closure, based on 1995 and 1996 profiles, also becomes deeper to the east, varying from -5.0 m (NGVD 1929) at Rockaway to -7.6 m at Montauk. Sand dunes are higher and more voluminous to the east. Another finding is that the Long Island beaches have a seasonal cycle, with more sand on the beaches during fall and less in spring.

Massive sediment movement in the entrance correlates with El Ninos. Though inlet dynamics are not among the many phenomena already linked to El Ninos, this coupling, if valid for Willapa Bay, should apply to certain other inlets worldwide. Understanding how channels respond to an intensely studied, quasi-predictable phenomena will improve guidance for management of the affected inlets. JF - Coastal Sediments: Proceedings of the ...

Such features can significantly influence sediment transport in their vicinity, therefore, their influence should be considered when sediment transport models are applied to areas where hardbottoms exist. This modeling effort was undertaken to investigate the area's cross shore sediment transport dynamics in order to quantify its potential beach recession. The study was accomplished with an enhanced version of the Storm-induced BEAch CHange model (SBEACH), which was modified through inclusion of an algorithm designed to account for the presence of hardbottoms. Due to the lack field data, previous efforts to calibrate and verify the hardbottom algorithm were based largely on the results of moveable bed physical model studies. This paper provides an assessment of the algorithm's modeling performance when compared to recent field measurements of storm-induced changes to Fort Pierce beach profiles. A further objective of this study was the development of a beach recession versus frequency of occurrence relationship characteristic of the area. This was accomplished through integration of the cross shore sediment transport modeling results with a relatively new joint probability analysis methodology, the Empirical Simulation Technique (EST).

Model results suggest that chronology is important (e.g., Southgate, 1995), but field verification is difficult to find (Southgate and Capobianco, 1997). Here we examine the upper shoreface response at the Field Research Facility (FRF), Duck, North Carolina to storms and groups of storms. We extend the analysis of Lee et al. (1998) to include data from 1981 to 1998 and examine the importance and character of storm sequences in terms of duration, intensity, intervening time interval, and profile response. The upper shoreface changes correlate well with storm groups that are shown to occur frequently (every 22 month on average). The largest storm group with an integrated wave power of 7.5X10 (super 10) joules was found to have a return period of about 20 years. However, using calculated return periods based on individual storms, an individual storm of this intensity has a return period of more than 1,000 years. Storm groups don't allow the profile time to recover and appear to have an additive impact producing changes typical of less frequent, longer duration and more intense storms.

This paper presents a general formulation of the net transport rate into which many cross-shore transport formulas may be cast, thus providing a basis for developing beach profile change models that can display predictive capabilities over a wide scale range. The net transport rate is expressed in terms of the deviation from an equilibrium shape and a forcing function which is related to the governing hydrodynamics. Transport formulations ranging from the scale of the individual wave period to seasons are discussed. A more detailed derivation of a transport rate formula for the offshore at the seasonal scale is provided and combined with the sediment volume conservation equation to yield predictions of beach profile evolution.

A new impermeable, south jetty was completed in 1991 and dredging of a 90-m-wide, 3-m-deep, mean low water (mlw) navigation channel was complete in early 1992. Additional dredging associated with construction of the south jetty increased the minimum cross-sectional area by 40-45%. Yearly bathymetric surveys collected since 1992 show definitive change in the flood shoal configuration. Deflation of the two main lobes, an increase in the southwest marginal area, and a general broadening of the shoal feature has been observed. The main navigation channel has migrated to the southwest and a small incised channel through the shoal has become more pronounced. The overall volume of the shoal has not changed significantly since project completion, whereas, historically the shoal feature had shown growth. Volume loss from the higher elevations is extensive. Sediment volume above the -1.0 m North American Vertical Datum 1988 (NAVD88) contour has been reduced by 70% and sediment volume above the -0.5 m NAVD88 contour has been reduced by 95%. The higher elevations have been planed off and sediment has shifted bayward. The tidal prism and inlet cross-sectional area have returned to values similar to the early history of the engineered project. JF - Coastal Sediments: Proceedings of the ...

The resulting tidal inlet behavior is complex and dynamic. Most important in terms of impacts to neighboring shorelines is the tendency for beach sediments to deposit in the flood and ebb tidal shoals. As a portion of this sand is permanently lost from neighboring beaches, significant erosion can occur. Consequently, the planning and design of shore protection projects adjacent to inlets must be based on an understanding of the interaction between the inlet and neighboring shorelines. This paper outlines the engineering and morphologic histories of Fire Island, Moriches and Shinnecock Inlets, which are within the Federally authorized Fire Island Inlet to Montauk Point, New York, Combined Beach Erosion Control and Hurricane Protection Project study area. The analyses presented herein provide an overview of inlet studies currently underway in the development of inlet management and/or shore protection for the study area.

The wave characteristics and native sand size were held constant while 2 initial fill sand placement geometry configurations and 3 different fill sand sizes were observed for 150 minutes of oblique, monochromatic wave attack. Three existing beach nourishment evolution theories which involve diffusive theory were used to analyze the experiments. The results revealed that, when the fill sand is initially placed high on the berm, larger sand sizes are somewhat less transportable. By placing the sand high on the berm the nourishment is less of a perturbation, thus reducing sediment transport. When the fill sand is initially placed farther into the surfzone, the fill sand and native sand mix. Thus, the results preclude definitive conclusions. The three methods of analysis produced a range of results. The methods varied initial boundary conditions and the inclusion or exclusion of refraction effects around the nourishment. The range of results indicate that beach nourishment evolution prediction techniques are sensitive to initial conditions, refraction effects and sand sand sizes.

In-water data collection was performed concurrently at 3-4 locations, in a series of three deployments with duration ranging from 6 weeks to four months. Each monitoring location represented a distinct flow regime with respect to the MCR ebb-tidal delta. Deployment water depth ranged from 16-36 meters. Measured data included waves, tide, current profile through the entire water column, near bottom suspended sediment concentration, near bottom water temperature/conductivity, and seabed variation due to bedform activity. The MCR monitoring effort was sponsored by the U.S. Army Corps of Engineers and the U.S. Environmental Protection Agency for the purpose of improving techniques for predicting the fate of sediment subjected to wave and current action. This paper discusses the physical environment at MCR, the overall field data collection effort during 1997-1999, and investigates the observed response of bottom sediment (bedform activity) due to energetic processes of the MCR forcing environment. Results are reported in terms of the correlation between process and response data. Results based on the first deployment data set (August-October 1997) indicate that bedform activity of sand-sized sediment at MCR is affected more by incident waves than by bottom currents.

The presence of an ice cover can limit reaeration, resulting in additional depletion of oxygen to levels that are below those required to support aquatic life and degrade wastewater effluents. In addition, rivers that rely largely on groundwater inflow during the winter may already be suffering from oxygen depletion because of the generally low levels of oxygen in groundwater. While DO modeling of rivers in open water, warm weather conditions is successful, the additional complexities introduced by ice as well as limited continuous data regarding the biochemical characteristics of flow in ice-covered rivers have prevented the development of a relatively simple model for estimating DO in the ice-covered case.

Decreases in measured alkalinity were less than predicted based on reductions in ferrous iron. Two explanations were proposed for this anomaly: 1) some ferrous iron is absorbed onto the ferric hydroxide precipitate and removed via sedimentation without oxidation; or 2) a poly-ligand precipitate of ferric hydroxy sulfate reduces the alkalinity required for precipitation of ferric hydroxide. MINTEQ-A2, a computer geochemical equilibrium model, was used to predict the extent of adsorption of sulfate and ferrous as well as effects on electrokinetic parameters on coagulation and sedimentation of ferric hydroxide particles. Results are interpreted in the context of measured changes in chemical parameters in the two systems, chemical and physical characteristics of the sludge and suspended solids, rates of homogeneous (solution) and heterogeneous (adsorbed) oxidation of ferrous iron, and rates of oxygen and carbon dioxide transfer. The effects of adsorbed ferrous on diagenetic changes in stored solids are also discussed; these diagenetic changes may decrease maintenance requirements.

Likewise, the prehistoric archaeological material often contained within these deposits records the imprint of past habitation patterns. In order to properly read these two records, however, it is necessary to understand the linkage between stratigraphy, environmental change, and the dynamics of the formative geomorphic and hydrologic processes. Here we present a new 3D simulation model of drainage basin evolution, and illustrate how the model can be used to develop new insights into the role of process dynamics and environmental change in shaping the geoarchaeological record. The model tracks dynamic changes in topography across a triangulated finite-difference mesh, in response to a randomly-generated sequence of storms. Erosion and sedimentation are computed using a discharge-slope formulation for both detachment capacity and excess sediment transport capacity; net erosion at a point is equal to the lesser of these two. In order to realistically simulate floodplain processes, a dynamic meshing technique is used to link the landscape model with a 1D model of lateral channel migration and overbank deposition. The near-surface exposure age of each sediment layer deposited is used as a simple proxy for soil development and archaeological potential. The model is applied to a small drainage basin in the Flint Hills region of central Kansas. Maps of simulated stratigraphic patterns reveal systematic spatial variations in deposit ages and exposure history, both across the landscape and with depth at a given point. These patterns are closely tied to geomorphic setting, and they demonstrate the potential for variability in stratigraphy and archaeological potential both across a watershed and with depth. The simulations are compared with geomorphic and stratigraphic data from Fort Riley, KS. The model results imply that even in the absence of external forcing (e.g., climate change), the natural dynamics of channel erosion and sedimentation can generate spatial variability in valley fill stratigraphy and, consequently, in the age and archaeological potential of valley fill deposits.

Thin sections of adjacent pervasively deformed and undeformed sediment from the device reveal strain caps and pressure shadows, haloes, turbate structures, silt wisps and tails, boudins, laminations, clast reorientation, clast imbrication and bimodal clast fabric developed within the pervasively deformed sediment. X-Ray CT images of the adjacent sediment reveals particle alignment, mainly in the direction of shearing, as well as obliteration of incipient shear zones, homogenization, and reduction of porosity within the pervasively sheared sediment. The images also reveal a distinct decollement surface developed between the pervasively deformed and undeformed sediment. The above physical characteristics of pervasively deformed sediment produced under controlled laboratory conditions may be useful for identification of deforming beds associated with former ice sheets.

S. military installations; significance and research challenges AN - 52237025; 2001-035581 AB - The landscapes of many U. S. military installations show the scars of extensive gully erosion, often rendering military land unusable for training and some testing missions. Gully development often positively impacts other interrelated erosion processes in the area, resulting in accelerated soil loss. Development of gullies often negatively impacts other resources, such as soil moisture, ground water, streams, lakes, and wetlands, wildlife habitats, seed banks, and cultural resources. Deep gullies can be major safety hazards to vehicular traffic, especially during night training. Additionally, gully development may undermine structures and roads in certain soil and ground water conditions. Extensive gully development results in a strongly negative visual impact, suggesting poor land stewardship. As in the agriculture sector, however, there exists a significant knowledge gap with respect to the role of gully development in soil erosion and landscape evolution. Contrary to many land manager's perspectives, gully development may be the product of a complex mix of processes and conditions, not just overland flow. The mechanics of gully development are actually poorly understood, in particular the ways that various fluvial, mass movement, freeze-thaw, geochemical, and ground water processes work in concert to produce gullies. Consequently, gully development is generally not considered in soil erosion modeling and prediction, possibly resulting in substantial underestimation of soil loss. A well coordinated multi-disciplinary research team approach will be required to make meaningful progress in understanding, predicting, and remediating gully development on U. S. military installations. Specific areas of needed research include: individual and integrated studies of the role of various processes in gully initiation and growth; the significance of particular soil, ground water, and topographic conditions on accelerated gully development; the influence of military vehicles on gully growth; gully development systematics and modeling; and the integration of gully mechanics and products in soil erosion and landscape modeling.

In some instances, glaciohydraulic supercooling can create a thick, debris-rich basal zone that transports large volumes of sediment to the terminus. This process of ice accretion and sediment entrainment occurs subglacially, mainly in lobes when there is sufficient meltwater discharging along a steeply ascending bed beneath a flat or reverse sloping ice surface. Accretion entrains sediment created by glacier processes, sediments transported by subglacial streams and sediments in the bed, creating a unique debris pattern. Debris entrained during ice accretion can vary from 25 to 35% by volume and is released at the ice sheet terminus by ablation when exposed to air and sun, and by melting when buried by sediments. Ice marginal and fluvial materials are commonly recycled by these processes, as well as by accretion during ice advance. Hummocky ground and end moraines composed of resedimented diamictons and melt-out till are characteristic products formed at the terminus. The relative importance of primary versus secondary diamictons depends on factors such as climate, slope, meltwater availability. The nature of sediments and landforms produced by high debris content basal ice may be sufficient to identify former ice sheets lobes in which glaciohydraulic supercooling operated.

Glaciology; Alley et al., 1999, J. Glaciology; Evenson et al., 1999, Geol. Soc. America, Special Paper 322) we have demonstrated that "glaciohydraulic supercooling" and associated basal freeze-on is occurring at the Matanuska Glacier in southern Alaska. Summer ice growth (anchor ice terraces) and "frazil ice flocks" clearly demonstrate supercooling during high meltwater discharge at this large valley glacier. Based on observations of similar summer ice growth and frazil ice flocks along the margin of the Bering and Malispina glaciers in southeastern Alaska, we can now extend the process of glaciohydraulic supercooling to large, coastal piedmont glaciers ascending from over deepened basins. Ice marginal conditions at these glaciers however do not allow for observation of basal ice so it is yet to be demonstrated if basal freeze-on of debris laden ice, similar to that formed at the Matanuska Glacier, is being produced and preserved there. The fact that glaciohydraulic supercooling is occurring at glaciers of subcontinental size supports our contention that this process can operate at any glacier -- including lobes of the Laurentide and Scandinavian ice sheets -- when there is sufficient meltwater discharging along a steeply ascending bed beneath a flat or reverse sloping ice surface.

The efficacy of such data, particularly image data, is, however, not fully known. The use of imagery in conjunction with published data was investigated with respect to predicting fracture characteristics at two sites in weathered granite; field measurements were made at both sites to provide a basis for testing this procedure. Lineation strikes and lengths, determined from the x1y1, x2y2 coordinates, and joint dips, obtained from the literature for similar granites nearby, were used to generate 3-D lineation models for five scales of imagery ranging from 1:3,500 to 1:53,000 over each site. The models were sampled to obtain simulated lineation spacing, trace length, intensity, termination percent, and rock block width and volume for each image scale. These data were plotted against scale in log-log space in two ways: (1) simulated data from the 3-D lineation models alone and (2) simulated data from the lineation models with simulated data from a previously-developed 3-D field area model. Linear regression was used to obtain the equations for each best-fit line, and predictions for each variable were calculated from the regression equations. The predictions made using case (1) are unrealistic when compared to the field data, but predictions made using case (2), comparable to field measurements at the two sites, were realistic as well as accurate. These latter predictions are also comparable to predictions made using field data collected near the two sites.

Carolina Bays are circular to elliptical depressions located along the Gulf of Mexico and Atlantic Coastal Plains. Proposed processes of initiation and development of these karst-like features include meteorite impacts, substrate dissolution, wind, ice, marine waves and currents. Based on field studies throughout the Atlantic and Gulf Coastal Plains and on review of coastal plain literature, we propose that Carolina Bays initially developed as silica-karst features. During Pleistocene sea-level lowstands, water tables in the Atlantic Coastal Plain were up to 30 m lower than today. Large volumes of surface water collected in local topographic lows and/or areas of enhanced permeability and infiltrated through sandy substrates of the low-relief coastal plain. Localized infiltration of phreatic water induced extensive desilicification of the sandy and clayey substrates, resulting in volume loss and development of karst-like depressions. Particularly relevant to initial bay development was alteration of kaolinite to gibbsite, which can produce a 34-percent loss in clay material volume, and concurrent dissolution of iron oxide. The initial silica-karst depressions along the Atlantic and Gulf coasts were later modified by eolian and, perhaps, ice-push processes, which enhanced their elliptical form. The subsequent Holocene rise in sea level caused ground-water levels in the coastal plain to equilibrate near the present-day land surface. This curtailed geochemical weathering, as well as eolian and ice-related processes. Ground-water saturation partially reversed chemical reactions associated with intensive weathering of clays beneath the bays, masking evidence of the severe leaching that occurred during their initial formation. Silica-karst features, similar to Carolina Bays in their initial stages of development, are common geologic features. Moreover, silica-karst processes are active today in warm temperate, subtropical, and tropical areas in sandy substrates where ground-water levels are well below the ground surface and can cause subsidence or disrupt developing wetlands.

Like many other problems, both identification and implementation of ecologically and economically acceptable solutions is complex. Recognizing the scope of this issue and perceiving that limited progress had been achieved, the International Joint Commission (IJC) asked its Great Lakes Water Quality Board to review the magnitude of the problem and what progress had been made in managing contaminated sediment by Canada and the United States. In addition, the Commission also asked for an identification of obstacles to remediation and recommendations for solutions. This paper provides a synopsis of this work and a summary of an IJC workshop held in June of 1997, in Collingwood, Ontario. Six categories of obstacles to sediment remediation are discussed, potential solutions are identified, and a series of recommendations are proposed.

The presence of hydrocarbons, cis-1,2 dichloroethylene (DCE), and vinyl chloride, which are TCE transformation byproducts, in the shallow sandy aquifer downgradient of the apparent source area suggests the potential for reductive dechlorination of TCE. Analysis of groundwater for intrinsic remediation parameters strongly indicates that natural degradation is occurring. A hybrid remedy has been proposed for the site: monitored natural attenuation (MNA) and source area reduction are being considered to address groundwater, while bioventing has been selected for remediation of petroleum-contaminated soils.

Time series analysis techniques that include parametric spectra, auto-correlation, and cross correlation are utilized to identify low frequency rhythmic patterns in the shoreline. Non-stationarity and phase shifting of rhythmic patterns is identified via comparison of the shoreline changes for different time intervals. Probability density functions of the shoreline change rates are also investigated and found to be in reasonable accord with Gaussian filtered noise.

These sediment flows have been classified into four types based primarily on water content and sedimentological characteristics (Lawson, 1979a, 1982). Thin sections of flow deposits show a variety of micro-and mesoscale characteristics that vary according to water content of the source flow. Wet-type flow deposits are characterized in thin section by a well-defined parallel and imbricated microclast fabric and thin laminations resulting from laminar to plastic flow regimes. Dry-type flow deposits are characterized in thin section by bi- or polymodal or random microclast fabrics, greater textural heterogeneity, and deformational microstructures associated with plastic to brittle flow regimes. Thin laminations and a "laminar flow fabric" in wet-type flow deposits may be characteristic of sediment gravity flow in a glacial environment. Characterization of these microstructures supports the contention that micromorphological analyses can be used to elucidate sediment flow genesis and the conditions of the flow just prior to deposition. Thus, micromorphology may also be useful for differentiating sediment-flow type in Pleistocene diamictons in other locations.

Ice grows as frazil ice and anchor ice. Frazil ice grows unattached in high-velocity discharge water. Anchor ice grows at vent orifices, in subglacial conduits and canals, in moulins, and in fractures. Anchor ice can grow as large, debris-free platy crystals or, more commonly, as fine-grained, debris-rich laminated ice. To date, these types of summer ice growth have been reported at few glaciers and studied in detail at the Matanuska Glacier but we anticipate that glaciohydrologic supercooling and the associated ice growth are operating at numerous other glaciers with the appropriate geometries. The objective of this paper is to provide a photographic atlas, and brief explanation, of the ice growth forms and features observed at the Matanuska Glacier. We hope that it will enable other researchers to recognize the evidences of glaciohydrologic supercooling at additional glaciers and eventually establish glaciohydrologic supercooling, and the associated basal freeze-on, as a major debris entrainment and transportation mechanism.

Structural features in the basal zone were described and photographed to document and assess deformation mechanisms. Discrete shear is hypothesized to occur: 1.) within the deformable bed, 2.) between the basal ice and the underlying deformable bed, and 3.) along planes of weakness throughout the stratified basal ice. Geochemical processes are hypothesized to generate some of the observed characteristic features at the contact between the stratified basal ice and the overlying clean englacial ice. Glaciohydraulic supercooling and the associated basal freeze-on are prominent processes (during periods of low effective pressure) that characterize portions of Matanuska Glacier's subglacial drainage system within overdeepenings (Lawson et al., 1999; Alley et al., 1999). Recent observations made by E. B. Evenson and G. J. Larson demonstrate Malaspina Glacier, which is a modern analog to the Laurentide ice sheet, also experiences glaciohydraulic supercooling within some portions of its drainage system. Lawson has hypothesized (1979, 1981) that the basal freeze-on process may have been important in depositing landforms of the last glacial maximum. GIS is used to determine if conditions were appropriate for the occurrence of glaciohydraulic supercooling and the associated basal freeze-on in any portions of the Superior Lobe of the Laurentide ice sheet.

The Dredged Material Management Plan (DMMP) is addressing this need through a combination of technical studies and regional consensus building. A number of management options are under consideration to meet the Port's dredge material needs. The options consist of a mix of techniques that reduce or immobilize contaminants (decontamination, stabilization, contaminant reduction) to encourage beneficial use of dredged material, and the more traditional containment methods (islands, pits, upland disposal sites). The plan will consist of a mix of options of varying capacities, costs, timelines and benefits. The goal is to develop a comprehensive plan that will take the Port well into the twenty-first century.

Many geological phenomena are scale invariant and fractal. This paper examines the fractal dimensions of one- and two-dimensional joint patterns within the Dartmoor granite, obtained by box-counting and Cantor's Dust methods, and compares these with dimensions calculated for drainage patterns, lineations and tor distribution. A good similarity between the fractal dimensions was obtained. Those for vertical joint spacings varied from 0.70 to 0.84, for lineations, drainage patterns and tor locations dimensions varied from 1.63 to 1.69 and for joint spacings on large rock pavements, values varied from 1.43 to 1.58. This similarity suggests that the patterns analysed are scale invariant over scales ranging from 1:1 to 1:50,000 and is further evidence for the uniform structural control of landscapes and individual features over these spatial scales.

In 1997, the US Army Corps of Engineers have developed a new applied engineering tool and methodology called micromodeling, which uses a small-scale physical model to simulate sediment conditions in rivers and streams. Since the introduction of micromodels in 1994 by the St Louis District Corps of Engineers, the technology has been used to address a variety of sedimentation problems and issues.

Ten men rested for two hours during a standardized cold-air test (4.6 C) after two treatments: (1) 60 min of cycle exercise (Ex) at 55 percent peak O2 uptake and (2) passive heating (Heat). Ex was performed during a 35 C water immersion (WI), and Heat was conducted during a 38.2 C WI. The duration of Heat was individually adjusted (mean = 53 min) so that rectal temperature was similar at the end of WI in both Ex (38.2 C) and Heat (38.1 C). During the cold-air test after Ex, relative to Heat 1) rectal temperature was lower (P less than 0.05) from minutes 40-120, 2) mean weighted heat flow was higher (P less than 0.05), (3) insulation was lower (P less than 0.05), and (4) metabolic heat production was not different. These results suggest that prior physical exercise may predispose a person to greater heat loss and to experience a larger decline in core temperature when subsequently exposed to cold air. The combination of exercise intensity and duration studied in these experiments did not fatigue the shivering response to cold exposure.

We further hypothesized that an increased exercise Sa(O2) with AA exposure would enhance O2 transport and improve both peak O2 uptake, V(O2/peak/) rate, in ml/kg/min. Eight female lowlanders completed a V(O2/peak/) rate and Exh test at 70 percent of their altitude-specific V(O2/peak/) at SL and with AA exposure to 4300 m in a hypobaric chamber (446 mm Hg) in their early follicular and midluteal phases. Progesterone levels increased about 20-fold from the early follicular to midluteal phase at SL and AA. We conclude that, despite significantly increased progesterone levels in the midluteal phase, exercise V(E) rate is not increased at SL or AA. Moreover, neither maximal nor submaximal exercise performance is affected by menstrual cycle phase at SL or AA.

For reservoirs with high P sub(L) (>15 gm/m super(2)/yr), R sub(P) increased markedly with modest increases in R sub(T). Reservoirs with lower values of P sub(L) exhibited less dramatic responses in R sub(P) to changes in R sub(T). The water quality management implications of this are great since reservoirs for which marked changes in R sub(P) can occur with modest changes in R sub(T) are potential management loci within a drainage basin.

To evaluate nesting and nonnesting spotted owl responses to helicopter noise, we measured flush frequency, flush distance, alert behavior, response duration, prey delivery rates, female trips from the nest, and nest attentiveness during manipulated and nonmanipulated periods, 1995-96. Chain saws were included in our manipulations to increase experimental options and to facilitate comparative results. We analyzed stimulus events by measuring noise levels as unweighted one-third-octave band levels, applying frequency weighting to the resultant spectra, and calculating the sound exposure level for total sound energy (SEL) and the 0.5-sec equivalent maximum energy level (LEQ sub(max 0.5-sec)) for helicopters, and the 10-sec equivalent average energy level (LEQ sub(avg. 10-sec)) for chain saws. An owl-weighting (dBO) curve was estimated to emphasize the middle frequency range where strigiform owls have the highest hearing sensitivity. Manipulated and nonmanipulated nest sites did not differ in reproductive success (P = 0.59) or the number of young fledged (P = 0.12). As stimulus distance decreased, spotted owl flush frequency increased, regardless of stimulus type or season. We recorded no spotted owl flushes when noise stimuli were >105 m away. Spotted owls returned to predisturbance behavior within 10-15 min after a stimulus event. All adult flushes during the nesting season occurred after juveniles had left the nest. Spotted owl flush rates in response to helicopters did not differ between nonnesting (13.3%) and nesting seasons (13.6%; P = 0.34). Spotted owls did not flush when the SEL noise level for helicopters was less than or equal to 102 dBO (92 dBA) and the LEQ level for chain saws was less than or equal to 59 dBO (46 dBA). Chain saws were more disturbing to spotted owls than helicopter flights at comparable distances. Our data indicate a 105-m buffer zone for helicopter overflights on the LNF would minimize spotted owl flush response and any potential effects on nesting activity.

These two mechanisms of spread were studied in ponds located in Lewisville, TX over a two-year period. Stolons were determined to be the predominant mechanism for localized expansion in undisturbed areas. While some fragments were produced, they accounted for only 0.1% of the establishment of rooted plants in new quadrats. Peak production of fragments occurred in October and November, with fragment densities of 0.15 N m super(-2) d super(-1). Expansion by stolons occurred between June and November of each year, with higher rates of spread (up to 4.0 cm d super(-1) radial growth) observed in the second season.

Royle], then in dioecious hydrilla, at three temperature levels (25, 30, and 35 C) and contrasted over three periods of growth (8, 12 and 16 wks). Each biotype was grown under natural photoperiods, decreasing from 14 hrs (in Aug) over 8, 12, and 16 wks respectively to 12, 11, and 10 hrs (in Oct, Nov, and Dec). For both biotypes, total biomass and root-to-shoot ratios were significantly reduced at 35 C; greater biomass was produced both at 25 and 30 C. Increases in growth period generally enhanced total biomass and shoot production; however, shoot length was unresponsive to growth periods beyond 8 wks. The 35 C treatment strongly impeded tuber formation and eliminated the production of axillary turions; the number and biomass of these propagules peaked at lower temperatures under short photoperiods after 12 to 16 wks. Shoot elongation was stimulated with increases in temperature and was especially pronounced in the dioecious biotype. Notably, in the monoecious biotype, the number of shoots as a potential source of fragments, and tuber production (although reduced) occurred at relatively high levels under unfavorably high-temperature (35 C) conditions. These results suggest that monoecious hydrilla may be better adapted to high temperatures than previously shown, and that the distribution of both biotypes in the U.S. could overlap further in southern states.

Franco; PP/DF) and a lodgepole pine/Engelmann spruce forest (Pinus contorta Loud., Picea engelmannii Parry ex Engelm.; LP/ES) located on the eastern slopes of the Cascade Mountains in Washington state, USA, were examined following severe wildfire to compare total soil carbon and nitrogen capitals with unburned (control) forests. One year after fire, the average C content (60 cm depth) of PP/DF and LP/ES soil was 30% (25 Mg ha super(-1)) and 10% (7 Mg ha super(-1)) lower than control soil. Average N content on the burned PP/DF and LP/ES plots was 46% (3.0 Mg ha super(-1)) and 13% (0.4 Mg ha super(-1)) lower than control soil. The reduction in C and N in the PP/DF soil was largely the result of lower nutrient capitals in the burned Bw horizons (12-60 cm depth) relative to control plots. It is unlikely that the 1994 fire substantially affected nutrient capitals in the Bw horizons; however, natural variability or past fire history could be responsible for the varied nutrient capitals observed in the subsurface soils. Surface erosion (sheet plus rill) removed between 15 and 18 Mg ha super(-1) of soil from the burned plots. Nutrient losses through surface erosion were 280 kg C ha super(-1) and 14 kg N ha super(-1) in the PP/DF, whereas LP/ES losses were 640 and 22 kg ha super(-1) for C and N, respectively. In both forests, surface erosion of C and N was similar to 1% to 2% of the A-horizon capital of these elements in unburned soil. A bioassay (with lettuce as an indicator plant) was used to compare soils from low-, moderate- and high-severity burn areas relative to control soil. In both forests, low-severity fire increased lettuce yield by 70-100% of controls. With more severe fire, yield decreased in the LP/ES relative to the low-intensity burn soil; however, only in the high-severity treatment was yield reduced (14%) from the control. Moderate- and high-severity burn areas in the PP/DF were fertilized with similar to 56 kg ha super(-1) of N four months prior to soil sampling. In these soils, yield was 70-80% greater than the control. These results suggest that short-term site productivity can be stimulated by low-severity fire, but unaffected or reduced by more severe fire in the types of forests studied. Post-fire fertilization with N could increase soil productivity where other environmental factors do not limit growth.

This paper describes the injuries sustained in that operation. A total of 4,754 (US, N = 3,066; UK, N = 1,688) aircraft exits were made, causing a total of 137 (US, N = 73; UK, N =64) injuries in 117 personnel (US = 68; UK = 49). There were 15 hospital admissions (US = 8; UK = 7; p = 0.37) and no fatalities. The combined exit injury incidence was 24.6 injured soldiers per 1,000 exits. Lower extremity sprains, strains, and fractures accounted for the majority of injuries in US and UK forces. UK soldiers sustained significantly more of these potentially incapacitating injuries than US troops. The UK forces sustained significantly more closed head injuries than US forces. The UK forces also had significantly more soldiers with multiple injuries than US forces. Factors that may have influenced differences in injury incidence include differences in weight of personal equipment and possible differences between the drop zones.

Properties examined from ice cores included salinity, temperature, and ice structure. Salinities measured near zero at the surface, increasing to 3-5ppt at the ice-water interface. Ice crystal texture was dominated by columnar ice, comprising 90% of the ice sampled. Surface albedos of various ice types, measured with radiometers, showed integrated shortwave albedos of 0.1 to 0.3 for melt ponds, 0.5 for bare, discolored ice, and 0.6 to 0.8 for a deteriorated surface or snow-covered ice. Aerial photography was utilized to document the distribution of open melt ponds, which decreased from 12% coverage of the ice surface in late July at 76 degree N to almost none in mid-August at 88 degree N. Most melt ponds were shallow, and depth bore no relationship to size. Sediment was pervasive from the southern Chukchi Sea to the north pole, occurring in bands or patches. It was absent in the Eurasian Arctic, where it had been observed on earlier expeditions. Calculations of reverse trajectories of the sediment-bearing floes suggest that the southernmost sediment was entrained during ice formation in the Beaufort Sea while more northerly samples probably originated in the East Siberian Sea, some as far west as the New Siberian Islands.

The 14-day study diet concentrations used were 0, 500, 1250, 2000, 2500, and 5000 ppm; the 90-day study diet concentrations were 0, 200, 1000, and 3000 ppm tetryl in the diet. The calculated average daily tetryl intake was 32.1, 82.5, 130.3, 178.9, and 374.4 mg/kg body weight (BW) for females and 31.8, 80.0, 121.0, 170.5, and 349.7 mg/kg BW for males in the 14-day study. For the 90-day studies, the daily tetryl intake was 14.2, 68.8, and 199.0 mg/kg BW for females and 13.0, 62.4, and 179.6 mg/kg BW for males. In the 14-day study, there was a significant decrease in body weights (males), whereas relative (organ/body weight) liver and spleen (females), and kidney (males) weights were significantly increased in the 5000-ppm dose group. Hematological effects observed were decreased hemoglobin and hematocrit and an increased number of reticulocyts in females (2000 to 5000 ppm). Methemoglobin levels in males (2000 to 5000 ppm) and females (5000 ppm) and total blood protein and albumin levels in all groups of males and females (except 500 ppm) were significantly increased. Histopathological changes were observed in kidneys (deposition of cytoplasmic droplets) of all dose groups of male rats. In the subchronic (90-day) study, feed intake was reduced in all dose groups, but a significant decrease in terminal body weights was observed in females (1000 and 3000 ppm) and males (3000 ppm). An increase in the relative liver, kidney (1000-3000 ppm), and spleen (3000 ppm) weights were noted in both sexes. The hemoglobin content and red blood cell count were decreased whereas the reticulocyte count was elevated (3000 ppm) in both sexes at 45 and 90 days. Methemoglobin levels were increased in both sexes (1000 and 3000 ppm). Histopathological changes were noted in the spleen (pigment deposition and erythroid cell hyperplasia) of both sexes (3000 ppm) and kidneys (tubular degeneration and cytoplasmic droplets containing alpha-2-micro globulin) of male rats (1000 to 3000 ppm). A no observed adverse effect level (NOAEL) for both sexes was 13 mg/kg BW/day was determined.

The regulation promulgated by EPA, commonly referred to as the "Risk Management Plan" rule, will require a substantial fiscal, experiential, and human resource investment for installations that are required to comply. Primarily, most military installations that have to comply will do so for water disinfection or propane storage. In addition to regulatory liability, Section 112(r) rules also have a significant public affairs and facility security aspect. This article reviews the regulation to point out compliance challenges and presents methods for reducing or eliminating the need to be subject to the rule by employing safer, smarter business practices.

This study represents an attempt to measure facial sweating and to quantify its effects on fit factors of negative pressure, full-facepiece respirators. Respirator fit factor (FF) data were obtained while 14 subjects completed 30 minutes of treadmill walking at an intensity of 75% of age-predicted maximal heart rate in an aerosol test chamber under ambient environmental conditions. Subject facial and whole body sweat production were also measurement. Statistical analysis of the treadmill FF results showed that respiratory fit was significantly (P<0.05) degraded after 14 minutes of exercise. Sweat accumulation inside the respiratory facepiece averaged 30.9 plus or minus 15.5 g. However, no significant correlation of subject facial sweat production with overall FF values measured during exercise was found. The results of this study indicate that respirator FFs degrade significantly over time under moderate exercise and environmental conditions and suggest that facial sweat accumulation alone does not account for the reduced FF levels.

Although the presence of bactericidal antibody in serum has been correlated with immunity to meningococcal disease, mucosal immunity at the portal of entry may also play an important role. This study was undertaken to examine in mice the possibility of safely using native outer membrane vesicles (NOMV) not exposed to detergent as an intranasal (i.n.) vaccine. The mucosal and systemic responses of mice to intranasal and intraperitoneal (i.p.) vaccination with NOMV were compared over a range of doses from 0.1 to 20 mu g. Intranasal vaccination of mice with NOMV induced a strong systemic bactericidal antibody response, as well as a strong local immunoglobulin A immune response in the lung as determined by assay of lung lavage fluid by enzyme-linked immunosorbent assay and lung antibody secreting cells by enzyme-linked immunospot assay. However, 8- to 10-fold-higher doses of NOMV were required i.n. compared to i.p. to elicit an equivalent bactericidal antibody response in serum. Some NOMV vaccine was aspirated into the lungs of mice during i.n. immunization and resulted in an acute inflammatory response that peaked at 1 to 2 days postimmunization and was cleared by day 7. These results indicate that i.n. delivery of meningococcal NOMV in mice is highly effective in eliciting the production of both a mucosal immune response and a systemic bactericidal antibody response.

The Plasma Energy Pyrolysis System (PEPS) project provides an environmental compliance technology to reduce the cost of treatment and disposal of hazardous and toxic waste streams resulting from production or deactivation of military weapon systems or from military operations. Plasma arc technology applications enable the military to control and dispose of recalcitrant hazardous and toxic wastes regulated under Resource Conservation and Recovery Act amendments (RCRA), in addition to satisfying the increasingly stringent emission standards of the Clean Air Act (CAA) relevant to open burning/open detonation (OB/OD) practices within the military. A plasma arc processing unit can significantly reduce costs associated with conventional hazardous waste treatment technologies such as: sample characterization lead time, health and safety exposure risks to workers, and increased risks to the general public from accidents involving excavated and transported wastes. The development and field demonstration of plasma arc technology will provide a much-needed capability for military hazardous waste processing and disposal on a flexible basis.

This work examines the hydrophilicity and subsequent implications for mobility of WTR as a function of phosphate adsorption, pH, and dewatering. The utility of an extended Derjaguin-Landau-Verwey-Overbeek (DLVO sub(EX)) model for predicting changes in WTR colloidal hydrophilicity, as a function of phosphate adsorption, is also examined. An increase in phosphate adsorption, below monolayer coverage, resulted in an increased hydrophilicity, as indicated by a decreased mean WTR aggregate diameter. Phosphate adsorption beyond monolayer coverage resulted in an increase in mean WTR aggregate diameter, suggesting a decrease in particle hydrophilicity. This change in WTR hydrophilicity may be a result of phosphate bridging and/or a reduction in the solvency of water as a function of ionic strength. Undried WTR exhibited thermodynamic surface characteristics similar to that of polyacrylamide, a common water-treatment polymer. Dewatering of WTR, in drying beds, resulted in a transformation to a more hydrophilic material. Mobility of phosphate-amended WTR, in agricultural soils, will depend on the quantity of phosphate added, extent of dewatering, and equilibrium pH of the soil-WTR mixture. The DLVO sub(EX) model predicted that increases in WTR hydrophilicity caused by adsorption of phosphate onto WTR, will result in large energy barriers and may prohibit WTR adhesion in the primary minimum onto common soil minerals.

AN - 69116468; 9875229 AB - Exposure to high energy impulse noise (BLAST) caused by explosions, result in structural and functional damage to the hollow organs, especially to the respiratory and auditory systems. Lung damage includes alveolar wall rupture, edema and hemorrhage, and may be fatal. Previous observations at the molecular level using the rat model, suggested that secondary free radical-mediated oxidative stress occurs post exposure resulting in antioxidant depletion and hemoglobin (Hb) oxidation. This study examined whether a short period of pre-exposure supplementation with antioxidants would protect Hb from the effects of BLAST exposure. Six groups of male Sprague-Dawley rats (8/group) were gavaged with 800 IU vitamin E (VE) in 2 ml corn oil, 1000 mg vitamin C (VC) in 2 ml distilled water or 25 mg or (-lipoic acid (LA) in 2 ml corn oil for 3 days. Matched control groups were gavaged with the respective vehicles. On day 4, rats were deeply anesthetized and exposed to a simulated BLAST wave with an average peak pressure of 62 +/- 2 kPa. Rats were euthanized one hour post exposure and blood samples were obtained by cardiac puncture and analyzed using a hemoximeter. Post exposure oxygenation states (HbO2, O2 saturation, and O2 content) were markedly decreased, while reduced-Hb was increased. Supplementation with VE and LA reversed the trend and increased Hb oxygenation, but VC did not. This suggests that a brief dietary loading with pharmacological doses of VE or LA, but not VC shortly before BLAST exposure may be beneficial. Moreover, measurement of blood oxygenation may function as a simple semi-invasive biomarker of BLAST-induced injury applicable to humans.

Annals of Internal Medicine, 53:992-1016, 1960. AN - 70122098; 9848796 AB - Prophylactic hemodialysis has been employed in the treatment of 15 patients with acute renal failure due to acute tubular necrosis (12), bilateral renal cortical necrosis (two), and poststreptococcal glomerulonephritis (one). Dialyses, usually lasting six hours each, were begun before clinical evidence of uremia developed in each patient and/or before the nonprotein nitrogen reached 200 mg.%, and were repeated daily or often enough to maintain the nonprotein nitrogen below 150 mg.%. The hypothesis underlying this technic postulates (1) that wasting, sepsis and impaired wound healing in these patients may reflect tissue injury by the same dialyzable toxic agents which produce the uremic symptoms that are readily reversible by dialysis, and (2) that repeated dialyses should therefore prevent both clinical uremia and the later, often lethal sequelae. The results contrast dramatically with our own past experience in treating patients with acute renal failure with a carefully executed medical regimen together with hemodialysis on conventional indications. Except in one instance of crush injury with progressive intracerebral damage, and one brief occasion in another individual, these patients experienced a stable, convalescent clinical course, remained free of uremic symptoms or chemical imbalances, ate at least three meals daily which were unrestricted in amount and composition, and were ambulatory between dialyses unless confined to bed by associated disease. Wounds healed well. Infection either did not occur, or subsided after appropriate therapy. Fluid restriction was liberalized by means of ultrafiltration with dialysis. Regional heparinization of only the extracorporeal circuit eliminated actual or impending bleeding as a contraindication to dialysis. Chronic vessel cannulation made the frequent dialyses possible, but may have provided the route for repeated, transient bacterial contamination of the blood stream in the first hour of many dialyses. Marked anemia, despite reticulocytosis, moderate to mild weight loss and some mental deficit persisted in spite of the general clinical improvement and well-being. Three patients with tubular necrosis died after seven, 11 and 26 days of oliguria; both patients with bilateral renal cortical necrosis also succumbed, on the seventy-third and ninety-second days of renal failure, and after 29 and 40 dialyses, respectively. At autopsy, evidence of sepsis was conspicuously absent. The remaining 10 patients survived. Thus some, but not all, clinical manifestations of acute renal failure appear to be favorably influenced by prophylactic dialysis treatment. Our initial experience in this group of 15 patients does not of course prove that freedom from complications and a significantly better outlook for survival can be assured to patients with acute renal failure by these methods. However, it seems to offer a reasonable hope of this possibility which we cannot attach to management by medical measures alone, or by dialysis on conventional indications. If this hope is realized in greatly extended, subsequent series, then it seems inevitable that some form of prophylactic dialysis, or some equally effective alternative, should be adopted in treating the majority of patients with acute renal failure.

Uranium treatment levels were 0, 50, 500, 5000, 10000, and 25000 mg DU kg (super -1) soil. Three measures of soil function were made. Overall soil biological activity was assessed via measurement of soil respiration. Decomposition was assessed by measurement of mass loss of four different plant litter types: wood sticks, cellulose paper, high-N grass, and low-N grass. Mineral N availability in the microcosms was estimated using ion-exchange resin bags. Functional diversity of the microcosms was analyzed through the use of the Biolog-system of sole-C-utilization patterns. Soil respiration was the most sensitive measure of functional changes, with significant decreases observed starting at the 500 mg kg (super -1) treatment. No differences in N availability were observed across the U treatments. Litter decomposition was significantly decreased (P<0.05) at the 25000 mg kg (super -1) level relative to the control for all litter types except the high-N grass. Wood decomposition was reduced by 84% at the 25000 mg kg (super -1) treatment, cellulose paper by 68%, and low-N grass by 15%. Decreases in the functional diversity of the bacterial community were related to the observed decrease in soil respiration, and to the greater effect on decomposition of the lower-quality litter types.

During the growing season, the inlet served as a net source of phosphorus, primarily due to the release of phosphorus from the sediments. More phosphorus was released from the sediments of the inlet (600 kg) than was input from the upstream watershed (460 kg). This release was caused by high pH associated with high photosynthetic activity. During the remainder of the year, the inlet served as a net sink for phosphorus, retaining 6% of the phosphorus input from the watershed. Over the entire year, this wetland was a net source of over 500 kg of phosphorus to downstream Delavan Lake. A constructed riverine wetland upstream of Delavan Lake Inlet demonstrated a similar periodic release of phosphorus. However, in this case, the summer release of phosphorus was less than that trapped during the remainder of the year. The constructed wetland served as a net sink for approximately 20% of the input phosphorus on an annual time scale. The role of existing and constructed wetlands as phosphorus traps is complex. Wetlands can act as a source or a sink for phosphorus depending on the ambient conditions in the wetland. How a wetland fits into a rehabilitation plan depends upon its net retention efficiency and the importance of the periodic releases of phosphorus to downstream waters.

Using the wavenumber integration method, theoretically calculated seismograms show that installing the GSN sensors in a borehole 200 to 300 m deep, 10 km away from the Station, will significantly reduce the vehicle-generated noise and improve signal quality. Because the intrinsic attenuation of seismic waves propagating in the polar firn is low, most of the predicted noise reduction results from wavefront spreading, Rayleigh wave amplitude decay with depth, and from placing the sensors below the refractive waveguide that traps much of the seismic energy in the near surface layers.

During cold periods, the ice accumulations and ice jams that form on this reach can delay or suspend winter navigation, incurring great costs to industry as well as cities and towns whose economies depend on river commerce. Much of this ice originates in the Missouri River. With the onset of warmer air temperatures, the rapid release of these ice accumulations can result in substantial damage to river structures such as dikes, revetments, and levees. This study analyzed historical data and used numerical hydraulic models to assess the possibility of structural solutions to these ice problems. The study identified reach locations where structural ice control might be possible. A simple computer model then simulated the upstream progression of ice covers on the middle Mississippi to assess the feasibility of various ice control alternatives. An ice retention structure located on the Missouri River near its mouth was found to be the most favorable of the structural ice control options considered.

AN - 21267689; 11702184 AB - Trichloroethylene (TCE) was found as a contaminant in the well supplying water to an aquatic testing laboratory. The groundwater was routinely screened by a commercial laboratory for volatile and semivolatile compounds, metals, herbicides, pesticides, and polychlorinated biphenyls using U.S. Environmental Protection Agency methods. Although TCE was the only reportable peak on the gas chromatograph, with average concentrations of 0.200 mg/l, other small peaks were also present, indicating the possibility that the contamination was not limited to TCE alone. A chronic 6-month carcinogenicity assay was conducted on-site in a biomonitoring trailer, using the Japanese medaka fish (Oryzias latipes) in an initiation-promotion protocol, with diethylnitrosamine (DEN) as the initiator and the TCE-contaminated groundwater as a promoter. Study results indicated no evidence of carcinogenic potential of the groundwater without initiation. There was, however, a tumor-promotional effect of the groundwater after DEN initiation. A follow-up laboratory study was conducted using reagent grade TCE added to carbon-filtered groundwater to simulate TCE concentrations comparable to those found in the contaminated groundwater. Study results indicated no promotional effects of TCE. These studies emphasize the necessity for on-site bioassays to assess potential environmental hazards. In this instance, chemical analysis of the groundwater identified TCE as the only reportable contaminant, but other compounds present below reportable limits were noted and may have had a synergistic effect on tumor promotion observed with the groundwater exposure. Laboratory toxicity testing of single compounds can produce toxicity data specific to that compound for that species but cannot take into account the possible toxic effects of mixtures of compounds.

AN - 19887640; 4499359 AB - The use of airboats is expanding in Alaska, particularly in the interior. This study describes the nature, magnitude, and distribution of disturbances caused by airboat trails over floating mat fen wetlands in the Tanana Flats near Fairbanks, Alaska. Airphoto interpretation showed over 300 km of airboat trails by 1995, with a 15% expansion of the trail system since 1989. Field sampling was done at 30 trail and adjacent control sites along this trail system to assess changes in hydrology, soils, and vegetation. Water velocities in the trails at two-thirds of the sites were at least an order of magnitude greater than velocities of less than 1.5 cm sec super(-1) in the control areas. On average, 30 cm of the 0.5-0.75 m thick floating mat has been removed or eroded by airboat traffic at the sampling locations. Nearly all emergent floating mat vegetation has been destroyed (5% cover remaining on average) so that the trails resemble a highly visible open water stream channel 2-3 m wide through the floating mats. Although the recovery and regrowth potential of floating mats in trails in high, recovery is unlikely in trails with continuing use.

Measurements on each 10-cm-wide segment included forces in three directions and the moment about a horizontal line parallel to the indentor face. During the tests in 1998, we also installed four pressure-sensing panels on the face of the segmented indentor and measured interfacial pressure during indentation tests at three speeds. We present the results from the load cells and the pressure-sensing panels. We obtained data on the actual contact area and the magnitude of interfacial pressures from the pressure-sensing panels. We observed both a `line-like' contact during high-speed (3- and 30-mm s super(-1)) indentation tests, and a gradually enlarging contact area attributable to creep deformation of the ice during low-speed (0.3-mm s super(-1)) indentation tests. Using the results of a brittle flaking model from the literature, we estimate the apparent fracture toughness of the ice from the data on interfacial pressure and the width of the contact area. Taking creep and fracture properties into account, we present a theoretical model to estimate the speed at which the transition from ductile to brittle failure of ice takes place during ice-structure interaction.

It is a mixture of 60 wt% 2,2'-dichlorodiethyl sulfide ("HD" or "sulfur mustard") and 40 wt% bis-(2-(2-chloroethylthio)ethyl) ether (T). Because HT reacts with water to form primarily the alcoholic compounds thiodiglycol (TDG) and bis-(2-(2-hydroxyethylthio)ethyl) ether (T-OH), disposal might be accomplished by combining hydrolysis with biodegradation. The half-lives of H and T in a well-agitated 3.8% HT/water reaction at 90%C were 1.4 and 1.6 minutes, respectively. The concentrations of both compounds were reduced to less than 1 mg/L within about 30 minutes. TDG is readily biodegradable. However, T-OH biodegradability has not been reported previously. HBr treatment converted HT ether-alcohol products to TDG. A comparative study of two hydrolysis/biodegradation approaches is reported here. HT was hydrolyzed (1) in water, and (2) in water then with HBr. Products were used as feed for separate aerobic sequencing batch reactors (SBRs), and bioreactor performances were compared. Although both feed solutions were detoxified in the SBRs, water hydrolysis alone yielded better overall bioreactor operation, a more favorable mass balance, and a simpler process than with the HBr step. Results indicated that although the HBr converted ether-alcohol products to TDG, the HT products were biodegraded with greater efficiency when the HBr treatment was omitted.

Damage progression and variability were measured on a conventional rubble mound exposed to depth-limited breaking waves in sequences of storms with varying wave conditions and water levels. Measurements were made of 16 or 32 damage profiles every 30 min of irregular wave action. Each measured profile was characterized by the eroded area, depth and length of the armor layer, and the remaining cover depth. The mean and standard deviation of these statistical variables changed with damage progression, whereas the probability distributions of the normalized variables were practically invariant. The mean and standard deviation of the damage variables are shown to be represented empirically by the mean eroded area alone. The damage variability along the breakwater was significant. Finally, an empirical formula is proposed to predict the mean eroded area in sequences of storms for these three tests.

One of the Y. pestis-specific plasmids, pMT1, is thought to promote deep tissue invasion, resulting in more acute onset of symptoms and death. We determined the entire nucleotide sequence of Y. pestis KIM5 pMT1 and identified potential open reading frames (ORFs) encoded by the 100,990-bp molecule. Based on codon usage for known yersinial genes, homology with known proteins in the databases, and potential ribosome binding sites, we determined that 115 of the potential ORFs which we considered could encode polypeptides in Y. pestis. Five of these ORFs were genes previously identified as being necessary for production of the classic virulence factors, murine toxin (MT), and the fraction 1 (F1) capsule antigen. The regions of pMT1 encoding MT and F1 were surrounded by remnants of multiple transposition events and bacteriophage, respectively, suggesting horizontal gene transfer of these virulence factors. We identified seven new potential virulence factors that might interact with the mammalian host or flea vector. Forty-three of the remaining 115 putative ORFs did not display any significant homology with proteins in the current databases. Furthermore, DNA sequence analysis allowed the determination of the putative replication and partitioning regions of pMT1. We identified a single 2,450-bp region within pMT1 that could function as the origin of replication, including a RepA-like protein similar to RepFIB, RepHI1B, and P1 and P7 replicons. Plasmid partitioning function was located ca. 36 kb from the putative origin of replication and was most similar to the parABS bacteriophage P1 and P7 system. Y. pestis pMT1 encoded potential genes with a high degree of similarity to a wide variety of organisms, plasmids, and bacteriophage. Accordingly, our analysis of the pMT1 DNA sequence emphasized the mosaic nature of this large bacterial virulence plasmid and provided implications as to its evolution.

AN - 70052506; 9801308 AB - 8-Oxoguanine (8-oxoG), induced by reactive oxygen species (ROS) and ionizing radiation, is arguably the most important mutagenic lesion in DNA. This oxidized base, because of its mispairing with A, induces GC-->TA transversion mutations often observed spontaneously in tumor cells. The human cDNA encoding the repair enzyme 8-oxoG-DNA glycosylase (OGG-1) has recently been cloned, however, its activity was never detected in cells. Here we show that the apparent lack of this activity could be due to the presence of an 8-oxoG-specific DNA binding protein. Moreover, we demonstrate the presence of two antigenically distinct OGG activities with an identical reaction mechanism in human cell (HeLa) extracts. The 38 kDa OGG-1, identical to the cloned enzyme, cleaves 8-oxoG when paired with cytosine, thymine and guanine but not adenine in DNA. In contrast, the newly discovered 36 kDa OGG-2 prefers 8-oxoG paired with G and A. We propose that OGG-1 and OGG-2 have distinct antimutagenic functions in vivo . OGG-1 prevents mutation by removing 8-oxoG formed in DNA in situ and paired with C, while OGG-2 removes 8-oxoG that is incorporated opposite A in DNA from ROS-induced 8-oxodGTP. We predict that OGG-2 specifically removes such 8-oxoG residues only from the nascent strand, possibly by utilizing the same mechanism as the DNA mismatch repair pathway.

We previously showed that immunization with either killed MBGV or a glycoprotein (GP) subunit prevented lethal infection in guinea pigs. In the studies reported here, an RNA replicon, based upon Venezuelan equine encephalitis (VEE) virus, was used as a vaccine vector; the VEE structural genes were replaced by genes for MBGV GP, nucleoprotein (NP), VP40, VP35, VP30, or VP24. Guinea pigs were vaccinated with recombinant VEE replicons (packaged into VEE-like particles), inoculated with MBGV, and evaluated for viremia and survival. Results indicated that either GP or NP were protective antigens while VP35 afforded incomplete protection. As a more definitive test of vaccine efficacy, nonhuman primates (cynomolgus macaques) were inoculated with VEE replicons expressing MBGV GP and/or NP. Three monkeys received packaged control replicons (influenza HA); these died 9 or 10 days after challenge, with typical MBGV disease. MBGV NP afforded incomplete protection, sufficient to prevent death but not disease in two of three macaques. Three monkeys vaccinated with replicons which expressed MBGV GP, and three others vaccinated with both replicons that expressed GP or NP, remained aviremic and were completely protected from disease.

AN - 70072548; 9821494 AB - Recent research demonstrates that silica phytoliths of dietary origin are associated with microwear of human teeth. Previous research has shown that severe enamel microwear and dental wear characterizes Archaic hunter-gatherers in the lower Pecos region of west Texas. Calcium oxalate crystals are especially common in Archaic coprolites. The vast majority are derived from prickly pear and agave, which were the dietary staples in west Texas for 6,000 years. The calcium oxalate phytoliths are harder than enamel. Therefore, calcium oxalate crystals are the most likely source of previously documented dental microwear and wear in the lower Pecos region.

AN - 70062683; 9822127 AB - Although rhesus monkeys are considered to be an appropriate model for inhalational anthrax in humans, an alternative for vaccine and therapeutic efficacy studies is desirable. This study characterized the pathology of lethal anthrax in rabbits challenged by subcutaneous inoculation and aerosol exposure. New Zealand white rabbits were exposed by subcutaneous inoculation or aerosol to lethal doses of Bacillus anthracis spores. The pathology of anthrax in rabbits exposed by either route was similar, with principal findings occurring in the spleen, lymph nodes, lungs, gastrointestinal tract, and adrenal glands. The cardinal changes were hemorrhage, edema, and necrosis, with bacilli and limited leukocytic infiltration. Features that depended on the route of exposure included mediastinitis in aerosol-exposed rabbits, a primary dermal lesion after subcutaneous inoculation, and differences in the pattern of lymph node involvement. Lesions observed in rabbits were comparable to those of inhalational anthrax in humans and rhesus monkeys. Noteworthy differences included the lack of leukocytic infiltration in brain and meningeal lesions, the relatively mild mediastinal lesions, and a lower incidence of anthrax-related pneumonia in rabbits compared with humans. These differences may be attributed to the greater susceptibility of rabbits to anthrax. Increased susceptibility is associated with both reduced leukocytic response to the bacilli and a more rapid progression to death, which further limits development of leukocytic infiltrates in response to the basic lesions of hemorrhage and necrosis. Primary pneumonic foci of inhalational anthrax, which may be influenced by preexisting pulmonary lesions in humans, were not observed in our rabbits, which were free of preexisting pulmonary disease. Anthrax in rabbits may provide a useful model for evaluating prophylaxis and therapy against inhalational anthrax in humans.

AN - 70012078; 9792170 AB - Synthetic genes encoding non-toxic, carboxyl-terminal regions (approximately 50 kDa) of botulinum neurotoxin (BoNT) serotypes A and B (referred to as fragment C or HC) were constructed and cloned into the methylotropic yeast, Pichia pastoris. Genes specifying BoNTA(HC) and BoNTB(HC) were expressed as both intracellular and secreted products. Recombinants, expressed intracellularly, yielded products with the expected molecular weight as judged by SDS PAGE and Western blot (immunoblot) analysis, while secreted products were larger due to glycosylation. Gene products were used to vaccinate mice and evaluated for their ability to elicit protective antibody titers in vivo. Mice given three intramuscular vaccinations with yeast supernatant containing glycosylated BoNTA(HC) were protected against an intraperitoneal challenge of 10(6) 50% mouse lethal doses (MLD50) of serotype A neurotoxin, a result not duplicated by its BoNTB(HC) counterpart. Vaccinating mice with cytoplasmically produced BoNTA(HC) and BoNTB(HC) protected animals from a challenge of 10(6) MLD50 of serotype A and B toxins, respectively.

AN - 70008653; 9795391 AB - The neurotoxins from Clostridium botulinum (BoNT serotypes A-G) exert their lethal effect by preventing the release of acetylcholine at the neuromuscular junction. As with tetanus toxin, immunization with a non-toxic fragment, the 50 kDa C-terminal portion of BoNT/A (Hc; residues 861-1296), protects mice against lethal challenges with the intact toxin. To locate the neutralizing epitopes, several protective monoclonal antibodies (mAbs) against BoNT/A-Hc were isolated and cloned. Specific binding of the mAbs to BoNT/A-Hc was demonstrated by surface plasmon resonance, with Kas in the range of 10(-10) to 10(-11) M. These antibodies recognized a genetically engineered polypeptide (1150-1289) that was previously shown to induce protective immunity. Prior to the determination of the X-ray crystal structure of the tetanus neurotoxin Hc fragment, molecular modelling studies indicated that it contained two highly solvent-exposed loops. Based on these predictions, two 25-mer Hc-peptides corresponding to these two regions were synthesized and were demonstrated to bind the neutralizing mAbs. Mice immunized with the Hc-peptides had high levels of antibodies that recognized BoNT/A-Hc. However, immunizations with only one of the Hc peptides protected when mice were challenged with BoNT/A. On the basis of these analyses, it should be possible to develop small peptides that could be useful in the design of future vaccines against these neurotoxins.

From full-scale and small-scale tests, the ultimate load to cause complete penetration of a floating ice sheet is much higher than that to cause the first radial crack. This can be attributed to wedging action during deformation of a radially cracked ice sheet. We present three approaches taken to determine the ice penetration force: (1) plastic limit analysis, (2) small-scale experiments, and (3) full-scale measurements in the field. Small-scale experiments were conducted with freshwater ice in the basin at the laboratory to understand the wedging action during the vertical loading of floating ice sheets. Results of the following series of experiments are presented: (a) beams with fixed ends, (b) paired cantilever beams arranged free-end to free-end and loaded together, (c) beams with an apparatus inserted between the free ends of paired cantilever beams to measure the in-plane force during vertical loading, and (d) vertical downward loading of floating ice sheets with fixed and free boundaries. Analysis of the data from the beam tests reveals that the wedging action results in the development of wedging pressure in the top or bottom third of the ice thickness, and this results in a resisting moment that counters the deformation of a cracked ice sheet. An ice sheet attached to the basin wall inhibits the propagation of radial cracks because of the wedging action, whereas an ice sheet free at the edges from the surrounding ice sheet fails by the propagation of radial cracks all the way to the ice sheet's free boundary. The difference between the two breakthrough loads of the free and the fixed ice sheets can be attributed to wedging action. The results of the beam tests are used in the results of plastic limit analysis to predict the breakthrough loads of floating ice sheets, which are in agreement with loads measured during full-scale and small-scale experiments.

Common features of this paradoxical syndrome were dilute primary electrolytes with physical exhaustion and muscle weakness after rapid free water intake. A pattern of skipping meals, working in a hot and humid environment, and consuming large volumes of water as "protection against becoming a heat casualty" predisposed these troops to the physical impairment that they intended to avoid. The mechanisms leading to both appropriate and inappropriate physiological responses to free water replacement are discussed as a basis for avoiding this specific heat casualty situation.

The summer population size in 1996, estimated by mark-recapture methods, was 292 individuals that were age 2 or older. Instantaneous total mortality rate (Z), estimated with a catch curve, was 0.41, for an annual mortality rate of 34%. Modeling the population with Z = 0.41 resulted in declining populations under two different recruitment scenarios. Mortality rates will have to be reduced to Z = 0.16-0.24 for the population to be self-sustaining by 2023, the target year in the Gulf Sturgeon Recovery Plan. Mean fork length of Gulf sturgeon in the Pearl River system was significantly larger in 1970 than in 1985 and 1992-1996, indicating that the population may not have improved since 1985. An increase in population size should be detectable within 6 years of achieving acceptable levels of mortality. Efforts to reduce mortality should focus on commercial bycatch and improving winter habitat in the Lake Pontchartrain estuary and summer habitat in the Pearl River system. Weirs in the Pearl and Bogue Chitto rivers need further study to determine if improved fish passage would improve recruitment and survival of Gulf sturgeon.

Plasmodium falciparum, the most virulent of the four malaria parasites of humans, adheres to a molecule called chondroitin sulphate A (CSA) on the surface of syncytiotrophoblasts (cells lining the intervillous space) and sequesters in the human placenta. Here we show that anti-adhesion antibodies, which limit the accumulation of parasites in the placenta, appear in pregnant women from Africa and Asia who have been pregnant on previous occasions (multigravidas), but not in those who are pregnant for the first time (primigravidas). Anti-adhesion antibodies against CSA-binding parasites are strain-independent and are associated with greatly reduced prevalence and density of infection. We conclude that malaria susceptibility in primigravidas is related to the lack of these anti-adhesion antibodies, and that an anti-adhesion vaccine for maternal malaria may be globally effective.

AN - 73951087; 9746584 AB - Recombinant botulinum neurotoxin serotype A binding domain [BoNT/A(Hc)], expressed in Pichia pastoris, was developed as a vaccine candidate for preventing botulinum neurotoxin type A (BoNT/A) intoxication. After fermentation and cell disruption, BoNT/A(Hc) was purified by using a three-step chromatographic process consisting of expanded-bed chromatography, Mono S cation-exchange chromatography, and hydrophobic interaction chromatography. Two pools of immunogenic product were separated on the Mono S column and processed individually. Both products were more than 95% pure and indistinguishable by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, Western blot analysis, and enzyme-linked immunosorbent assay (ELISA). Each protein was assayed for potency in mice at immunogen doses ranging from 2.4 ng to 10 microg, followed by challenge with 1,000 mouse intraperitoneal 50% lethal doses (i.p. LD50) of BoNT/A. The calculated 50% effective dose for both peaks was approximately 0.1 microg/mouse. Peak 1 was evaluated further in a mouse efficacy assay. Mice were injected either once, twice, or three times at five different doses and subsequently challenged with 100,000 mouse i.p. LD50 of BoNT/A. In general, multiple injections protected better than one, with complete or nearly complete protection realized at doses of >/=0.5 microg/mouse. Serum neutralization and ELISA titers were also determined. Tellingly, 82 of 83 mice with antibody titers of >/=1, 600, as measured by ELISA, survived, but only 6 of 42 mice with titers of 4m. During each storm group, offshore sediment movement caused a distinct outer bar to migrate offshore and grow in size resulting in an abrupt increase in the volume of sediment on the upper shoreface. The net profile changes were much larger than the changes due to single storms and the cumulative effect of the storms can be considered as one "event". During these events, the first storm appears to have a destabilizing effect on the profile which has insufficient time to recover before the second (and subsequent) storm(s). As a result, several storms in quick succession are able to have a large impact on the morphology. The intervening periods between the groups of storm events (termed fairweather conditions) lasted up to 4 years. They are characterized by slow, but steady sediment redistribution (averaging 33 m (super 3) m (super -1) year (super -1) ) from the upper shoreface (>5m depth) toward the shore, while the total sediment volume was effectively constant. The onshore feed of sediment was not significantly affected by individual storms during the fairweather conditions. These two processes of (1) morphologic change during groups of storm events and (2) the steady onshore feed of sediments from the shoreface during fairweather conditions appear to play an important role on medium- and long-term profile evolution at least at Duck.

Equations for the celerities of points along the wave profiles are developed from the solutions and are related to the kinematic wave and dynamic wave celerities. The linear solutions are compared systematically in a series of case studies to evaluate the differences caused by inertia. These comparisons use the celerities of selected profile points, the paths of these points on the x-t plane, and complete profiles at selected times, and indicate general agreement between the solutions. Initial diffusion wave inaccuracies persist over relatively short time and distance scales that increase with the wave diffusion coefficient and Froude number. The nonlinear monoclinal wave solution parallels that of the linear dynamic wave, but is applicable to arbitrarily large flow increases. As wave amplitude increases, the monoclinal rating curve diverges from that for a linear wave, and the maximum Froude number and energy gradient along the profile increase and move toward the leading edge. A monoclinal diffusion solution for the diffusion wave equations is developed and dynamic wave-diffusion wave comparisons are made over a range of amplitudes with the same case studies used for linear waves. General dimensionless monoclinal-diffusion profiles exist for each depth ratio across the wave, whereas corresponding monoclinal wave profiles exhibit minor, case-specific Froude number dependence. Inertial effects on the monoclinal profiles occur near the leading edge, increase with the wave amplitude and Froude number, and are responsible for the differences between the dimensionless profiles.

The affinity of CT for the complex required the presence of the Ni super(2+) ion, since CT was unable to bind in its absence. Binding was mediated by the B-subunit (CTB) as both CT and CTB bound to the resin, but not the A-subunit (CTA). Binding was reversible in the presence of imidazole and suggested that the affinity of CT for the Ni super(2+) ion was mediated by His residues. The heat-labile enterotoxin of Escherichia coli (LT), which is closely related to CT, was unable to bind to the Ni super(2+) ion. Comparison of amino acid sequences revealed the presence of three His residues in CT (positions 13, 57 and 94), but only one in LT (position 57). To confirm that the residues at positions 13 and 94 of CTB were responsible for the binding, they were changed to residues found in LTB. Changing His13 times Arg completely abrogated the ability of CTB to bind to Ni super(2+) ion. In contrast, the mutation of His 94 times Asn reduced, but did not abrogate, the ability of CTB to bind to Ni super(2+) ion. Based on calculated interatomic distances, it is unlikely that His13 and His94 are part of the same complex. There appear to be two separate binding sites, with the principal site involving His13 and a much weaker site involving His94. This latter site can only participate in binding if the complex involving His13 has formed.

Rickettsial antigen was detected by application of a simple direct or amplified immunocytochemistry procedure and an indirect immunofluorescent procedure. In the direct procedure alkaline phosphatase conjugation to the mouse polyclonal antibody to the Karp strain was followed by the HistoMark Red test system to detect rickettsial antigen. The amplification procedure used a similar method but used an unlabeled primary antibody followed by secondary biotinylated antimouse IgG, streptavidin-alkaline phosphatase, and the HistoMark Red test system. The immunofluorescent procedure included a biotinylated secondary antibody followed by addition of a streptavidin-FITC conjugate. Specific tissue tropisms in infected chiggers were observed in the salivary, glands, nervous tissue, and ovaries of adult female mites in all procedures; however, nonspecific fluorescence of the chigger limited definitive identification of tissue tropisms with the indirect immunofluorescent procedure.

New associations between chiggers, rodents, and O. tsutsugamushi in active rice agriculture areas, an ecological habitat not described previously, are reported. Rattus rattus (L.) was the most common species (representing 85.8% of the 1,433 rodents processed), followed by Rattus losea (Swinhoe) (9.4%), Bandicota indica (Bechstein) (3.6%), and Rattus argentiventer (Robinson and Kloss) (1.3%). O. tsutsugamushi was isolated from 30% of the R. rattus and R. losea, 29% of the B. indica, and 33% of the R. argentiventer collected. Mean minimum infection rates were 0.03 in Leptotrombidium chiangraiensis Tanskul & Linthicum, a new species of chigger, and 0.002 in Leptotrombidium imphalum (Vercammen-Grandjean & Langston), a chigger species not previously associated with scrub typhus transmission. Efficient vertical and horizontal transmission of O. tsutsugamushi by L. chiangraiensis and L. imphalum was demonstrated. During a 19-mo period from October 1993 to April 1995, the overall prevalence of human IgM and IgG antibody to O. tsutsugamushi was 25.5 and 47.6%, respectively. L. chiangraiensis and L. imphalum are incriminated as vectors of O. tsutsugamushi in a rice field habitat associated with a focus of antibiotic resistance.

This protein is associated with secretory vesicles of nerve terminals and is a substrate for four of the seven serotypes of botulinum neurotoxin (BoNT). The DNA for the recombinant peptide was amplified by the polymerase chain reaction and cloned into the pTrxFus vector. The resulting synaptobrevin peptide was expressed as a thioredoxin fusion protein in E. coli and released into the medium by osmotic lysis. The 18.7-kDa thioredoxin-synaptobrevin protein, designated as TSB-51, is intended for use in a cell-free assay to test potential inhibitors of BoNT/B-mediated proteolysis of synaptobrevin with the ultimate aim of developing clinically effective therapeutic agents to counteract botulism. Incubation of TSB-51 with the purified light chain of BoNT/B resulted in proteolysis which was evident within 30 min and increased with time until completion ( similar to 4 hr). Cleavage of TSB-51 appeared to be at the appropriate BoNT/B cleavage site as indicated by a reduced intensity of the 18.7-kDa band and the appearance of a band at 16.4 kDa on Tris-tricene polyacrylamide gradient gels. The concentration of free Zn super(2+) had a significant effect on the cleavage rate; low Zn super(2+) concentrations stimulated substrate cleavage, whereas high concentrations were inhibitory. Cleavage was not significantly depressed by the naturally occurring metalloprotease inhibitor phosphoramidon when tested at concentrations up to 5 mM. TSB-51 appears to be a useful substrate for studying BoNT/B and is expected to aid in the discovery of effective BoNT inhibitors.

The authors found this vaccine to also be ineffective against F1-negative (F1 super(-)) Y. pestis strains, which have been isolated from a human case and from rodents. For these reasons, the authors developed a recombinant vaccine composed of a fusion protein of F1 with a second protective immunogen, V antigen. This vaccine protected experimental mice against pneumonic as well as bubonic plague produced by either an F1 super(+) or F1 super(-) strain of Y. pestis, gave better protection than F1 or V alone against the F1 super(+) strain, and may provide the basis for an improved human plague vaccine.

Adjuvants tested included i) aluminum hydroxide (Alhydrogel), ii) saponin QS-21 and iii) monophosphoryl lipid A (MPL) in squalene/lecithin/Tween 80 emulsion (SLT). Animals were immunized once with either 50 mu g of recombinant PA plus adjuvant, or with Anthrax Vaccine Adsorbed (AVA), the licensed human anthrax vaccine. The serological response to PA was measured by enzyme-linked immunosorbent assay. Lymphocyte proliferation and serum neutralization of in vitro lethal toxin cytotoxicity were also assayed. In all vaccine groups, anti-PA IgM and IgG titers peaked at 2 weeks and 4-5 weeks postimmunization, respectively. Five weeks postimmunization, animals in all vaccine groups demonstrated PA-specific lymphocyte proliferation and sere that neutralized in vitro cytotoxicity. Six weeks after immunization, the animals were challenged by aerosol with approximately 93 LD sub(50) of virulent anthrax spores. Animals were bled daily for 1 week to monitor bacteremia, and deaths were recorded. Anti-PA ELISA titers in all groups of immunized animals were substantially increased 2 weeks after challenge. One dose of each vaccine provided significant protection (>90%) against inhalation anthrax in the rhesus macaques.

Subtype-specific monoclonal antibodies (MAbs) directed toward two variable regions (VR1 and VR2) of the class 1 protein of Neisseria meningitidis are used in this classification scheme. A new MAb was developed to classify a nonsubtypeable (NST) strain of N. meningitidis, 7967. This MAb bound to both the NST strain and the prototype subtype P1.14 strain, S3446, by dot blot analysis. However, a MAb produced to the prototype P1.14 strain did not bind to strain 7967. Sixteen additional strains were further identified as P1.14 with the prototype MAb; of these, 15 strains bound both MAbs. Differences in the characteristics of binding of both antibodies to the three apparently diverse P1.14 strains were studied further by using outer membrane complex proteins, immobilized peptides, and soluble peptides. Deduced amino acid analysis suggested that both MAbs bind to VR2 and that single amino acid changes within VR2 (KM, NM, or KK) might explain the differences in binding characteristics. These results demonstrated that minor variations which exist within subtype variable regions may be clearly identified only by a combination of molecular and immunologic testing. The impact of subtype variation will become more evident as subtype-specific vaccines are developed and tested for efficacy.

Spontaneous organophosphate utilization (OPU) mutants were isolated that efficiently utilized these alternate sources of phosphate. A genomic library was constructed from one such OPU mutant, and two genes were isolated that conferred the OPU phenotype to strain JA221 upon transformation. These genes were identified as phnE and glpT. The original OPU mutation represented phnE gene activation and corresponded to the same 8-bp unit deletion from the cryptic wild-type E. coli K-12 phnE gene that has been shown previously to result in phnE activation. In comparison, sequence analysis revealed that the observed OPU phenotype conferred by the glpT gene was not the result of a mutation. PCR clones ot glpT from both the mutant and the wild type were found to confer the OPU phenotype to JA221 when they were present on the high-copy-number pUC19 plasmid but not when they were present on the low-copy-number pWSK29 plasmid. This suggests that the OPU phenotype associated with the glpT gene is the result of amplification and overproduction of the glpT gene product. Both the active phnE and multicopy glpT genes facilitated effective metabolism of low concentrations of DIPP, whereas only the active phnE gene could confer the ability to break down a chromogenic substrate, 5-bromo-4-chloro-3-indoxyl phosphate-p-toluidine (X-P sub(i)). This result indicates that in E. coli, X-P sub(i) is transported exclusively by the Phn system, whereas DIPP (or its metabolite) may be transported by both Phn and Glp systems.

PCBs are highly resistant to dechlorination and persist for long periods of time in the environment. Documented spills of PCB-contaminated fluids occurred at a federal scrap yard, where, historically, capacitors containing PCB dielectric fluid were crushed. The purposes of this investigative, industrial hygiene study were: (1) to evaluate the potential occupational health hazards and associated impacts experienced by environmental personnel involved in site investigation and environmental sampling activities at the federal scrap yard; (2) to characterize environmental personnel exposures to airborne concentrations of PCBs (42 and 54% chlorine); and (3) to determine airborne concentrations of PCBs at specific worksite locations of maximum anticipated air contaminant concentration. Air samples were collected and analyzed in accordance with National Institute for Occupational Safety and Health Method 5503 and U.S. Army Environmental Hygiene Agency Technical Guide No. 141. I concluded that: (1) the airborne concentrations of PCBs present during site investigation and environmental sampling activities at the federal scrap yard did not present or cause an occupational health hazard; (2) all sampled employees were exposed to personal BZ air concentrations of PCBs less than Occupational Safety and Health Administration (OSHA) and American Conference of Governmental Industrial Hygienist (ACGIH) exposure assessment criteria; (3) all environmental GA air concentrations of PCBs at specific worksite locations of maximum anticipated air contaminant concentration were less than the OSHA and ACGIH exposure assessment criteria; and (4) all employees wore adequate and appropriate personal protective clothing and equipment ensembles.

AN - 79993964; 9662424 AB - The novel inhibitor 7-N-phenylcarbamoylamino-4-chloro-3-propyloxyisocoumarin (ICD 1578) was tested for its ability to antagonize the zinc metalloprotease activity of botulinum toxin B (BoNT/B). The efficacy of this compound was tested in a cell-free system using a 50-mer synaptobrevin peptide as substrate. The peptide, designated as [Pya88] S 39-88, had a fluorescent amino acid analog, L-pyrenylalanine (Pya), substituted for the normal Phe88 of synaptobrevin-2. Cleavage by BoNT light chain yielded fragments of 38 and 11 amino acids, respectively. The smaller fragment, containing the Pya fluorophore, was readily separated and quantified by fluorescence spectroscopy at 377 nm. In the presence of 7-200 microM ICD 1578, cleavage of [Pya88] S 39-88 was progressively reduced (IC50 = 27.6 microM), and 100 microM ICD 1578 produced >95% inhibition. For comparison, captopril, a well-known zinc metalloprotease inhibitor, generated less than 10% inhibition at a concentration of 5 mM. ICD 1578 is the most potent antagonist of BoNT/B light chain thus far described.

Currently it contains two relatively elaborate & usable examples of lessonware on which authors can build - one in Arabic & the other in Spanish. A proof of principal version of MILT's two-dimensional Arabic microworld was developed, which uses speech rather than keyboard input to control an animated agent in solving an authored problem. The speech is recognized using a Dragon discrete speech recognizer utilizing a relatively small modern standard Arabic speech model. This version of the MILT microworld is controlled by 70 spoken Arabic sentences. The limitations of discrete speech recognition means that spontaneous speech recognition is impossible & the expected utterances must be presented for reading. As a result, three of the Arabic sentences are written at a time on the bottom of the microworld screen & students read aloud the sentence that they wish to see executed. When such a command is recognized & executed, the system automatically replaces the sentences with another set of three, & so forth. An evaluation of this speech-driven microworld produced significant, positive learning effects & useful attitudinal information from students. As a result, the discrete speech recognizer in MILT is being replaced by a continuous recognizer, & the two-dimensional microworld is being replaced by a three-dimensional one. 13 Figures, 19 References.

AN - 80053005; 9694426 AB - More is known about the time course for the acquisition of human heat acclimation during exercise than its decay or loss. Pioneering research in the 1940s led to our early understanding of the heat acclimation process and its subsequent decay with further knowledge concerning the associated physiological mechanisms in later years. For both hot-dry and hot-humid environments, nearly complete exercise-heat acclimation occurs after 7 to 10 days of exposure. However, about two-thirds to 75% of the physiological adjustments and improvements in performance are seen in 4 to 6 days. Individuals with high levels of aerobic fitness are partially but not fully acclimated to the heat. Most of the early studies on decay or loss of heat acclimation are flawed by very small samples, incomplete heat acclimation or inappropriate measurements. Nevertheless, these studies are pioneering in a sense because they indicate that the retention of heat acclimation is quite variable between individuals and environments. Retention of the benefits of heat acclimation appears to remain longer for dry compared to humid heat. High levels of aerobic fitness seem associated with greater retention of heat acclimation. Further well-designed and definitive studies on decay or loss of heat acclimation appear necessary.

AN - 79930194; 9621344 AB - This study describes the neural structures damaged following exposure to the nerve agent soman, shows there are time-dependent differences in the extent of damage in certain structures, and relates seizure-induced increases in delta band (0-3.5 Hz) electroencephalographic (EEG) activity with severity of subsequent neuropathology. Rats, instrumented to record cortical EEG activity, were pretreated with the oxime HI-6 (125 mg/kg, i.p.) and then challenged with soman (180 ug/kg, s.c.). All animals developed continuous epileptiform seizures that lasted in excess of 4 hr. Groups of animals were perfused 1, 3, 10 or 30 days following exposure. Paraffin-embedded brains were stained with hematoxylin and eosin; thirty-four neural structures were examined and scored for neural damage. All cortical areas sustained damage, with piriform and perirhinal cortices exhibiting the most severe. Subcortical limbic areas (amygdala, amygdala-piriform transition zone, hippocampus, claustrum) and various thalamic nuclei were most consistently and severely damaged in all animals regardless of survival time. Brainstem structures, cerebellum, spinal cord, and other motor output nuclei were never damaged. It was found that some structures were rated as more severely damaged when evaluated at shorter survival times. Severity of neural damage was related to high levels of EEG delta power recorded 24 hr after exposure; power during the acute seizure or 24 hr body weight loss did not predict lesion severity. Sections between AP -0.8 to -4.8 contain cortical and subcortical structures that can be readily and reproducibly evaluated for brain damage.

AN - 70089547; 9842444 AB - Coxiella burnetii phase I whole cell vaccine (WCV) is associated with risk of severe local delayed-type hypersensitivity (DTH) reactions in previously immunized individuals or those sensitized by natural exposure. We compared this vaccine to another investigational vaccine derived by chloroform-methanol extraction of phase I whole cells (chloroform-methanol residue vaccine, CMRV). Hairless guinea pigs, sensitized with either WCV or CMRV, were given 60,600 and 6,000 ng of WCV or CMRV in an intradermal (i.d.) skin test. The i.d. administration of WCV consistently caused more host reactions than comparable doses of CMRV in guinea pigs sensitized with either WCW or CMRV, suggesting that CMRV may be a safer vaccine. However, the CMRV was not innocuous and caused significant indurated lesions and micro-abscesses at the 600 ng and 6,000 ng skin test sites.

The site was a gasoline station located at the edge of Crissy Field, a former wetland adjacent to San Francisco Bay. The wetland was filled in for the 1915 Pan Pacific Exposition and used as an airfield beginning in the 1920s. Now part of the Golden Gate National Recreation Area, the area is being restored to reflect historical conditions, including a freshwater riparian corridor through the site. Migration of the gasoline plume in alluvial and beach deposits has been retarded by interbedded fine-grained organic-rich estuarine deposits (bay muds) and an upward gradient. The plume has stabilized after migrating approximately 250 feet northward toward the bay in preferential pathways in the first waterbearing zone. Gasoline concentrations have fluctuated seasonally but decreased only slightly over five years of monitoring. The site's location at the transition from an alluvial to estuarine geologic setting complicates the demonstration of biodegradation using geochemical signatures. Site-wide low concentrations of electron acceptors (dissolved oxygen and nitrate) and high concentrations of biodegradation byproducts (methane and dissolved iron and manganese) appear to be primarily the result of microbial biodegradation of naturally-occurring organic carbon. The effect of the fuel on the groundwater chemistry is more subtle and largely masked. Primary lines of evidence (plume length and fuel concentrations) must be relied upon more than secondary lines of evidence (intrinsic biodegradation parameters) in demonstrating natural attenuation at this site.

Home range size was estimated for each male using minimum convex polygon, harmonic mean, adaptive kernel, and fixed kernel-based methods. Minimum convex polygon and harmonic mean home ranges were significantly larger than those previously reported for Ferruginous Hawks. Home ranges varied substantially among males (mean = 90.3 km super(2), range = 17.7-136.4 km super(2)). There was no relationship between home range size and brood size; however, there was a significant relationship (r super(2) = 0.964, P = 0.018) between home range size and the distance from the nest site to the nearest irrigated agricultural field where some males hunted. Kernel-based estimates showed two distinct core areas for most males, one around the nest and a second in the agricultural fields where they hunted.

DMDNB is a white, odorless solid that sublimes at room temperature. It has been proposed as a chemical tag to aid in detection of plastic explosives, which cannot be easily detected by conventional field sampling methods. Toxicologists at the U.S. Army Center for Health Promotion and Preventive Medicine have proposed an occupational exposure limit (OEL) for DMDNB of 0.15 mg/m super(3). Due to the low OEL, worker exposure during the manufacture of plastic explosives is of considerable concern. In this method of collection and analysis, DMDNB vapor is collected on a Tenax sampling tube at a rate of 200 mL/min. The chemical is desorbed from the collection media with ethyl acetate. The concentration of the analyte is determined using a gas chromatograph fitted with an electron capture detector and a nonpolar 20-m X 0.53-mm capillary column with a flow rate of 5 mL/min of carrier gas. The tested range was 0.15 to 15 mu g/tube with a calculated minimum detection limit for the method of 0.07 mu g/tube. In routine analyses a calibration curve is generated from 0.01 mu g/tube (0.006 mu g/mL of solution) to 6 mu g/tube (3 mu g/mL of solution), bracketing 0.07 mu g/tube. There was no breakthrough of DMDNB up to a loading of 65 mu g/tube. DMDNB was stable at room temperature on the collection media for up to 21 days. The effects of humidity on the collection was tested from 25% humidity to a saturated atmosphere. There was no observable effect on the collection efficiency of DMDNB until a saturated atmosphere was reached, and then the efficiency dropped.

Production estimates were compared to estimates of benthic consumption by blue crabs, shrimp, and epibenthic fish. There was no evidence that dredged material disposal had a detrimental impact on benthic production; however, production was low throughout the entire bay the year following dredged material disposal, which may have obscured an assessment of the impact of disposal. In fact, disposal sites yielded both the highest production estimates and species richness in both the upper and lower bay areas 2 yr after disposal. Of the five estimation methods used, two that incorporated environmental parameters (temperature and depth) yielded similar and moderate results, ranging from 1.1 g ash-free dry weight m super(-2) yr super(-1) to 26.9 g ash-free dry weight (AFDW) m super(-2) yr super(-1) over the 4 yr studied. Daily food ration estimates applied to fishery-independent trawl-survey data yielded overall benthic consumption estimates ranging from 1.1 g AFDW m super(-2) to 1.7 g AFDW m super(-2). A second method of estimating consumption, which used transfer efficiency estimates and annual fisheries statistics produced slightly lower benthic consumption estimates (0.72-1.13 g AFDW m super(-2)). The average consumption estimate exceeded benthic production in the upper bay in one of the 4 yr for which benthic production was estimated. In years with high benthic production, the estimated benthic food requirement of epibenthic predators was roughly 10-15% of benthic production. Variation in annual benthic production estimates was two to three times greater than the variation in consumption estimates.

This paper presents evidence demonstrating ice feet at tidewater margins in Glacier Bay, Alaska. Ice feet are likely sources of many submarine icebergs originating at the ice margin. The cause of ice foot development is unclear, but may represent a change in fracture behavior near the bed where higher debris concentrations affect fracture propagation and calving. Ice foot formation can be favored by englacial discharge and sediment ramps along the glacier margin that can cause differential melting of the ice cliff. The presence of ice feet is important to understanding ice-proximal sediment dynamics because they are a primary source of debris-rich icebergs and their calving affects sediment redistribution patterns.

(white oak), bottomland Quercus nigra L. (water oak), bottomland Fraxinus pennsylvanica Marshall. (green ash) and flood-tolerant Nyssa aquatica L. (water tupelo) seedlings were studied under controlled conditions. Net photosynthetic rates of flooded N. aquatica seedlings were reduced by 25% throughout the 32-day flooding period. Net photosynthetic rates of flooded Q. alba seedlings fell rapidly to 25% of those of the control seedlings by Day 4 of the flooding treatment and to 5% by Day 16. In F. pennsylvanica and Q. nigra, net photosynthetic rates were reduced to 50% of control values by Day 8 but remained at approximately 30 and 23%, respectively, of control values by Day 32. Leaves of flooded Q. alba seedlings accumulated approximately twice as much starch as leaves of non-flooded control plants, whereas root starch concentrations decreased to 67% of those of control plants by the end of the 32-day flooding treatment. In contrast, flooding caused only a small increase in leaf starch concentrations of N. aquatica plants, but it increased root starch concentrations to 119% of those of the control plants by the end of the experiment. The co-occurring bottomland species, Fraxinus pennsylvanica and Q. nigra, differed from each other in their patterns of stomatal conductance and root starch concentrations. We conclude that the maintenance of low leaf starch concentrations, and high pre-flood root tissue starch concentrations are important characteristics allowing flood-tolerant species to survive in flooded soils.

Evidence is presented here that free or liposome-encapsulated RTS,S, a particulate malaria antigen consisting of hepatitis B particles coexpressed with epitopes from the Plasmodium falciparum circumsporozoite protein, also was localized in the trans-Golgi after incubation with BMs, suggesting processing by the class I pathway. An in vivo cytotoxic T-lymphocyte (CTL) response was detected, however, only after immunization with RTS,S encapsulated in liposomes containing lipid A and not after immunization with free RTS,S or with RTS,S encapsulated in liposomes lacking lipid A. Therefore, intracellular delivery of antigen containing CTL epitopes to the Golgi of BMs does not necessarily result in a CTL response in vivo unless an additional adjuvant, such as liposomes containing lipid A, is utilized. Encapsulation of RTS,S in liposomes containing monophosphoryl lipid A (MPL) resulted in a dose-dependent enhancement of the NANP-specific immunoglobulin G (IgG) antibody response compared to that of free RTS,S. The IgG1 and IgG2a subclasses predominated after immunization with RTS,S encapsulated in liposomes containing MPL. These results demonstrate that encapsulation of a lipid-containing particulate antigen, such as RTS,S, in liposomes containing lipid A can enhance both humoral and cellular immune responses.

DnaK Leads to Increased Thermal Stability of UvrA, Catalytic UvrB Loading, Enhanced Repair, and Increased UV Resistance AN - 16480852; 4348258 AB - UvrA is one of the key Escherichia coli proteins involved in removing DNA damage during the process of nucleotide excision repair. The relatively low concentrations (nanomolar) of the protein in the normal cells raise the potential questions about its stability in vivo under both normal and stress conditions. In vitro, UvrA at low concentrations is shown to be stabilized to heat inactivation by E. coli molecular chaperones DnaK or the combination of DnaK, DnaJ, and GrpE. These chaperone proteins allow sub-nanomolar concentrations of UvrA to load UvrB through > 10 cycles of incision. Guanidine hydrochloride-denatured UvrA was reactivated by DnaK, DnaJ, and GrpE to as much as 50% of the native protein activity. Co-immunoprecipitation assays showed that DnaK bound denatured UvrA in the absence of ATP. UV survival studies of a DnaK-deficient strain indicated an 80-fold increased sensitivity to 100 J/m super(2) of ultraviolet light (254 nm) as compared with an isogenic wild-type strain. Global repair analysis indicated a reduction in the extent of pyrimidine dimer and 6-4 photoproduct removal in the DnaK-deficient cells. These results suggest that molecular chaperonins participate in nucleotide excision repair by maintaining repair proteins in their properly folded state.

AN - 79985031; 9655631 AB - Botulinum neurotoxin (BoNT) is known to produce cationic channels in artificial bilayers. This study examined ion channels formed by BoNT in native membranes from cultured PC12 cells under conditions approximating those thought to occur during toxin internalization. Membrane patches were excised from PC12 cells using patch electrodes and exposed to symmetrical solutions containing either 200 mM CsCl, RbCl or KCl. The patch pipettes also contained 1-5 microg/ml BoNT buffered to pH 5.3 while the bath solutions were buffered to pH 7.0. In the presence of toxin, bursts of ion channel openings were observed. These toxin-induced channels were most active with a negative voltage applied to the same side as the toxin (cis). The increased activity at negative voltages was due to an increase in mean open time of e-fold per 120 mV and a decrease in mean closed time between bursts of e-fold per 110 mV. The shorter mean closed time within a burst was independent of membrane voltage. While BoNT-induced ion channels started as a single conductance level of 27 pS (KCl), 34 pS (RbCl) or 46 pS (CsCl) they typically increased in roughly equal steps to five or more times the original channel conductance. These higher conductance BoNT 'channels' opened and closed synchronously and could be distinguished from superposition of multiple independent channels. Despite differences in putative transmembrane sequences between BoNT/A and BoNT/E, both serotypes evidenced the same channel conductance and mean open time.

AN - 79884074; 9597845 AB - An evaluation of the physiological effects on aviators of heat stress (90 degrees F wet bulb globe temperature [WBGT]) versus a cooler condition (70 degrees F WBGT) when wearing either a MOPP0 (Mission-Oriented Protective Posture 0) uniform or a MOPP4 ensemble encumbered with a ballistic chest plate and overwater survival gear was performed at the United States Army Aeromedical Research Laboratory. The study used a repeated-measures design with 14 aviators flying 4-hour missions in a UH-60 helicopter simulator. Average crew endurance in the MOPP4-hot condition was reduced to one-third of the fully completed mission time of 309 minutes. For the hot condition, core temperature in the simulator rose 1.4 degrees F/hour when aviators wore the encumbered MOPP4 ensemble versus 0.27 degree F/hour when they wore the MOPP0 uniform. Sweating rate in the MOPP4-hot condition was 1,523 ml/hour, resulting in 2.5% dehydration, in contrast to 183 ml/hour and 0.9% dehydration in the MOPP4-cool condition. In this study, pilots flying realistic UH-60 simulator sorties rapidly incurred significant physiological heat strain when wearing an encumbered MOPP4 flight ensemble in hot cockpit conditions.

AN - 69099836; 9861411 AB - The pharmacokinetics, metabolism, protein binding, red blood cell (RBC) binding, stability in vitro, and acute and anorectic toxicity of artelinic acid (ARTL) were investigated in various animal species and human blood samples. Absorption and distribution following 10 mg/kg intramuscular or oral administration in dogs and rats were very rapid with t1/2 0.12-0.54; there were also a high AUC (11,262 ng/h/mL) and Vss (9.5 L/kg), low CL (15 mL/min/kg) and long elimination time (t1/2 = 2.6 h), compared with rat data. Oral bioavailability of ARTL was 79.7% in dogs and 30.1% in rats. The conversion of ARTL to dihydroartemisinin (DART) in dogs (0.1-0.5% of total dose) after 3 routes of administration (intravenous, intramuscular and oral) was 10-fold lower than that in rats. In rats dosed with [14C]ARTL, unchanged ARTL accounted for less than 13% of the total radioactivity after all 3 administration routes, suggesting that ARTL was extensively biotransformed. The half-lives of total radioactivity (21-49 h) in urine were much longer than that of unchanged ARTL in plasma (1.4-3.7 h), indicating that some long-lasting metabolites of ARTL were formed in rats. The mass balance data showed that 77-83% of total radioactivity was recovered in urine and faeces. High binding capacity (79-95%) and low binding affinity (1.1-9.3 x 10-7 M) of ARTL were measured in rat, rabbit, dog, monkey and human plasma. The RBC/plasma ratios of [14C]ARTL were 0.35 and 0.44 for dog and human plasma, respectively. ARTL was much more stable than artesunic acid (ARTS) in rat and dog plasma, and both ARTL and ARTS were more stable in dog plasma than in rat plasma in vitro. The 50% lethal dose (LD50) of ARTL in rats was about 535 mg/kg. Multiple intramuscular dosing for 7 d of 50 mg/kg/d of ARTL caused mild anorectic toxicity compared to ARTS in rats. In contrast to 4 other artemisinin derivatives, ARTL seems to be a good antimalarial candidate as it has the highest plasma concentration, the highest binding capacities in RBC, the highest oral bioavailability, the longest elimination half-life, the lowest metabolism rate and the lowest toxicity at equivalent dose levels.

Beach profiles and breaking waves were measured together with the sediment sampling. The experiments were conducted on beaches with various sediment composition ranging from well-sorted fine sand to poorly sorted gravel and shell debris. The cross-shore variation of sediment mean grain size ranged from less than 1 phi to significant variation of up to 3.5 phi . The resultant database contains 99 vertical grain-size profiles, composed of 99 bottom samples and 552 trap samples taken throughout the water column and at 29 different locations along the southeast coast of the United States and the Gulf coast of Florida. A homogeneous vertical profile of mean grain size and grain-size distribution pattern was found on most of the beaches with a wide range of sediment sizes. The homogeneous vertical profile, representing 92% of the measurements, was found on all morphological features: swash zone, breaker line, mid-surf zone, trough, and bar. A homogeneous distribution indicates that the vertical mixing mechanism in the water column of the surf zone is independent of sediment size ranging from fine sand to fine pebbles. Bottom sediment, represented by an 8-cm core sample, was generally coarser than the sediment trapped in the water column.

The first line of defense against arthropod vectors is the use of personal protective measures. The concurrent application of DEET (N,N-diethyl-m-toluamide) repellent on the skin and permethrin[(3-phenoxy-phenyl)methyl( plus or minus )cis,trans-3-(2,2- dichloroethenyl)-2,2-dimethylcyclopropane-carboxylate] insecticide on the battle dress uniform, while the uniform is worn properly, is a personal protective strategy officially known as the DOD Insect Repellent System. It is important for troop commanders and field leaders to enforce the use of personal protective measures to prevent insect-borne infectious diseases and to ensure troop and soldier readiness. DEET is a safe and effective repellent. Permethrin is a synthetic pyrethroid insecticide and repellent. Used in conjunction with proper clothing and other personal protective equipment, these repellents provide the best known protection available and are critical in minimizing the occupational health threat of arthropod-borne diseases to troops in the field.

This research has identified two species (Pontederia cordata and Potamogeton nodosus) which offer the potential for long-term competitive control of nuisance L. wollei mats in shallow waters. Both species significantly impacted the distribution and total mass of L. wollei mats within planted experimental plots compared to adjacent unplanted control plots. The established plants forced a redistribution of the L. wollei biomass within the water column, preventing the formation of the characteristic summertime floating mats, the most objectionable of the many nuisance aspects of this species. In addition, the L. wollei biomass was reduced by more than 50% in planted plots. This reduction in mass may have been related to reduced light and nutrient availability within the vegetated plots. In addition, oxygenation and acidification of the benthic region may have promoted the decomposition and remineralization of the nuisance mat.

To characterize the structural topography of IpaD, the Geysen epitope-mapping system was used to identify epitopes recognized by surface-reactive monoclonal and polyclonal antibodies produced against purified recombinant IpaD or synthetic IpaD peptides. Surface-exposed epitopes of IpaD were confined to the first 180 amino acid residues, whereas epitopes in the carboxyl-terminal half were not exposed on the Shigella surface. By using convalescent-phase sera from 10 Shigella flexneri-infected monkeys, numerous epitopes were mapped within a surface-exposed region of IpaD between amino acid residues 14 and 77. Epitopes were also identified in the carboxyl-terminal half of IpaD with a few convalescent-phase sera. Comparison of IpaD epitope sequences with Salmonella SipD sequences indicated that very similar epitopes may exist in the carboxyl-terminal region of each protein whereas the IpaD epitopes in the surface-exposed amino-terminal region were unique for the Shigella protein. Although the IpaD and SipD homologs may play similar roles in transport, the dominant serum antibody response to IpaD is against the unique region of this protein exposed on the surface of the pathogen.

Because the X-ray crystal structure of the 50-kDa C-terminal half of the heavy chain of tetanus toxin was recently determined, this report evaluates the accuracy of these network-derived predictions. For this predominantly beta -strand-containing fragment, predictions, on a per-residue basis, for both secondary structure and solvent accessibility were about 70% accurate. A more flexible and realistic analysis based on overlapping segments yielded accuracies of over 80% for the three-state secondary structure and for the two-state accessibility predictions. Because the accuracies of these predictions are comparable to those made by Rost and Sander using a dataset of 126 nonhomologous globular proteins, our predictions provide a quantitative foundation for gauging the results when building by homology the structures of related proteins.

AN - 79823763; 9560228 AB - Apurinic/apyrimidinic (AP) endonuclease (APE; EC 4.2.99.18) plays a central role in repair of DNA damage due to reactive oxygen species (ROS) because its DNA 3'-phosphoesterase activity removes 3' blocking groups in DNA that are generated by DNA glycosylase/AP-lyases during removal of oxidized bases and by direct ROS reaction with DNA. The major human APE (APE-1) gene is activated selectively by sublethal levels of a variety of ROS and ROS generators, including ionizing radiation, but not by other genotoxicants-e.g., UV light and alkylating agents. Increased expression of APE mRNA and protein was observed both in the HeLa S3 tumor line and in WI 38 primary fibroblasts, and it was accompanied by translocation of the endonuclease to the nucleus. ROS-treated cells showed a significant increase in resistance to the cytotoxicity of such ROS generators as H2O2 and bleomycin, but not to UV light. This "adaptive response" appears to result from enhanced repair of cytotoxic DNA lesions due to an increased activity of APE-1, which may be limiting in the base excision repair process for ROS-induced toxic lesions.

AN - 79761340; 9518496 AB - DNA polymerase beta is required in mammalian cells for the predominant pathway of base excision repair involving single nucleotide gap filling DNA synthesis. Here we examine the relationship between oxidative stress, cellular levels of DNA polymerase beta and base excision repair capacity in vitro , using mouse monocytes and either wild-type mouse fibroblasts or those deleted of the DNA polymerase beta gene. Treatment with an oxidative stress-inducing agent such as hydrogen peroxide, 3-morpholinosydnonimine, xanthine/xanthine oxidase or lipopolysaccharide was found to increase the level of DNA polymerase beta in both monocytes and fibroblasts. Base excision repair capacity in vitro , as measured in crude cell extracts, was also increased by lipopolysaccharide treatment in both cell types. In monocytes lipopolysaccharide-mediated up-regulation of the base excision repair system correlated with increased resistance to the monofunctional DNA alkylating agent methyl methanesulfonate. By making use of a quantitative PCR assay to detect lesions in genomic DNA we show that lipopolysaccharide treatment of fibroblast cells reduces the incidence of spontaneous DNA lesions. This effect may be due to the enhanced DNA polymerase beta-dependent base excision repair capacity of the cells, because a similar decrease in DNA lesions was not observed in cells deficient in base excision repair by virtue of DNA polymerase beta gene deletion. Similarly, fibroblasts treated with lipopolysaccharide were more resistant to methyl methanesulfonate than untreated cells. This effect was not observed in cells deleted of the DNA polymerase beta gene. These results suggest that the DNA polymerase beta-dependent base excision repair pathway can be up-regulated by oxidative stress-inducing agents in mouse cell lines.

AN - 79969873; 9643470 AB - We have shown that saxitoxin (STX) induced lethality can be reversed by 4-AP when it is administered at the time of respiratory arrest [Benton, B. J., Spriggs, D. L., Capacio, B. R. and Chang, F.-C. T. (1995) 4-Aminopyridine antagonizes the lethal effects of saxitoxin (STX) and tetrodotoxin (TTX). International Society of Toxicology, 5th Pan American Symposium on Animal, Plant and Microbial Toxins, Frederick, MD. July/August 1995, p. 217]. The purpose of this study was to determine whether 4-AP's efficacy could be enhanced further when administered at different times relative to STX intoxication. The animals used in this study were chronically instrumented for concurrent recordings of diaphragm electromyogram (DEMG), neck skeletal muscle electromyogram, Lead II electrocardiogram, and electrocorticogram (ECoG). There were five groups of unanesthetized guinea pigs. The first group served as 4-AP controls and received a 2 mg/kg i.m. dose of 4-AP. The four remaining groups were given a lethal dose of STX (5 microg/kg i.m.); the second group, STX controls, received no 4-AP; the third group, the 4-AP treatment group, received 4-AP immediately following cardiorespiratory collapse; the fourth group was the 4-AP/STX co-administration group and 4-AP was given concurrently with STX; and the fifth group was the 4-AP pretreatment group in which 4-AP was given 10 min before STX. At the point of STX-induced cardiorespiratory collapse, the guinea pigs were ventilated and given an i.p. injection of sodium bicarbonate. Results showed that 4-AP prevented cardiorespiratory collapse in 3/7 animals in the 4-AP pretreatment group. Also, 4-AP in conjunction with artificial ventilation and sodium bicarbonate accelerated recovery from STX-induced cardiorespiratory collapse in all the treatment groups compared to the STX controls.

AN - 79891841; 9600547 AB - Generalized convulsive status epilepticus (GCSE) is the most common and potentially most damaging form of status epilepticus (SE). It has been previously reported, in both human GCSE and animal models of GCSE, that the electroencephalographs (EEGs) and electrocorticographs (ECoGs) recorded during GCSE contain an ordered sequence of five identifiable patterns: discrete seizures (phase 1), waxing and waning ictal discharges (phase 2), continuous ictal discharges (phase 3), continuous activity with flat periods (phase 4), and periodic epileptiform discharge on a flat background (phase 5). In this paper, we report the same pattern of ECoG changes in 15 rats exposed to soman, an acetylcholinesterase (AChE) inhibitor. Phase 1 was observed in 12 of 15 animals, but phases 2-5 were recorded in all the animals. Taken together, these findings suggest that the sequence of EEG changes is independent of the initiating cause, represent a common electrical response to GCSE, and reflect a common underlying neurochemical mechanism.

AN - 79773450; 9534976 AB - Bacterial superantigens, such as staphylococcal enterotoxin B (SEB), can trigger acute pathologic effects in humans. A hydrophobic loop on the surface of SEB and other bacterial superantigens, centered around a conserved leucine (L45) residue, is essential for binding to class II major histocompatibility complex molecules. Single residue changes of wild type SEB, designated Q43P, F44P, or L45R, resulted in nonlethal proteins at a dose equivalent to 30 murine LD50 of SEB. Relative to SEB, the mutant proteins did not elevate serum concentrations of proinflammatory cytokines in mice and caused minimal proliferation of human lymphocytes. Anti-SEB titers of mice immunized with Q43P, F44P, L45R, or SEB were similar and protected 77%-100% of animals against a lethal SEB challenge. Levels of toxin-specific IgG1, IgG2a, IgG2b, and IgG3 in mice immunized with SEB, Q43P, or F44P were equivalent, but animals immunized with L45R had significantly elevated levels of IgG2a and IgG2b. Vaccines against staphylococcal superantigens should focus on this critical leucine residue.

AN - 79614083; 10671186 AB - Two membrane-bound, reductive dehalogenases that constitute a novel pathway for complete dechlorination of tetrachloroethene (perchloroethylene [PCE]) to ethene were partially purified from an anaerobic microbial enrichment culture containing Dehalococcoides ethenogenes 195. When titanium (III) citrate and methyl viologen were used as reductants, PCE-reductive dehalogenase (PCE-RDase) (51 kDa) dechlorinated PCE to trichloroethene (TCE) at a rate of 20 micromol/min/mg of protein. TCE-reductive dehalogenase (TCE-RDase) (61 kDa) dechlorinated TCE to ethene. TCE, cis-1,2-dichloroethene, and 1,1-dichloroethene were dechlorinated at similar rates, 8 to 12 micromol/min/mg of protein. Vinyl chloride and trans-1,2-dichloroethene were degraded at rates which were approximately 2 orders of magnitude lower. The light-reversible inhibition of TCE-RDase by iodopropane and the light-reversible inhibition of PCE-RDase by iodoethane suggest that both of these dehalogenases contain Co(I) corrinoid cofactors. Isolation and characterization of these novel bacterial enzymes provided further insight into the catalytic mechanisms of biological reductive dehalogenation.

Using this collection, precise estimates have been made of the flux and mass distribution for 50-700-mu m cosmic spherules (melted micrometeorites). Allowing for the expected abundance of unmelted micrometeorites in the samples, the results indicate that about 90% of the incoming mass of submillimeter particles evaporates during atmospheric entry. The data indicate the loss of glass-rich and small stony spherules from deep-sea deposits, and they provide constraints for models describing the survival probability of micrometeoroids. (Auth. mod.)

Although response of the shoreline to the presence of coastal structures is fairly well understood and main trends can be predicted with mathematical models, little is known about the response of the beach profile to structures. In this paper, the shape of the beach profile near the seawall and groins is examined and compared to the shape distant from and, presumably, uninfluenced by the structures. Trends expected in beach-profile shape at the structures, based on general concepts of coastal-sediment processes, are compared to measured shapes. A procedure is also presented for estimating representative breaking wave heights as inferred from the morphology of the linear longshore bars at a site. Finally, two aspects of the accuracy of the sea-sled survey system not previously discussed in the literature are examined.

Each model is based on the physics of the ice accretion process and on empirical observations. However, these models predict significantly different ice loads for the same freezing rain storm, making it difficult to use model results to determine design ice loads. In this paper, we describe a simple ice load model that can be used to make conservative back-of-the-envelope calculations of ice loads based on the precipitation rate and wind speed. Using historical weather data from Springfield, IL, we compare the ice loads from this model with those from other models and discuss the reasons for the differences between them. We also compare the modeled and measured ice loads from one well-documented storm that occurred at CRREL's freezing rain weather station.

However, deposition and ablation together determine ice loads because ice persists after it is deposited, and residual ice often remains on structures, contributing to load when later ice accretion occurs. The goal of this study is to identify local and synoptic-scale weather conditions associated with rime and glaze ablation. A total of 77 ablation periods were recorded by time-lapse video for two winters on Mt Equinox, VT, USA. Weather information was acquired from on-site measurements, radiosondes and synoptic charts. Sublimation was the slowest process, whereas melt and mechanical ablation events were the most rapid, lasting less than 5 h. Ablation occurred principally during daylight hours. Wind speeds were similar and slowest during sublimation and melt, with sublimation occurring primarily in westerly winds, and melt occurring within southerly winds. Sublimation air temperatures and relative humidities were lowest, with medians of - 11 degree 3C and 57%, respectively. In general, melt is most frequent as storms approach, and sublimation is most common as storms depart.

A new method which replaces the C-weighted day-night average sound level has been recommended by Schomer, reviewed by the National Research Council, and incorporated into a new American National Standard. This new method is based almost exclusively on blast sound research. In this new method, as in the previous method, sonic boom sounds are included and assessed in the same way as blast sounds using the C-frequency weighting. It was shown more recently by Schomer that blast and sonic boom sounds could be assessed in the same way, although there was an indication that for the same C-weighted sound exposure level, a boom sound would be about 5 dB more annoying than a blast sound. This paper further analyzes both the data gathered during that original study (performed in 1995) and additional spectral data gathered using the same structures and the same noise sources in 1996. In particular, this paper analyzes if a metric that includes more of the low-frequency energies than does C-weighting can provide a more consistent assessment of high-energy impulsive sounds, thus reducing the apparent 5-dB discrepancy between subjective assessments of boom and blast sounds. This paper also analyzes the 1995 human response data using a method recommended by Vos. The Vos method accounts for about 2 one half of the 5-dB difference while the enhanced low-frequency weighting can account for almost the full 5-dB discrepancy. Finally, this paper finds that window accelerations in the structures used for this experiment were nonlinear in the mid-frequency range. In these structures, a 1-dB increase in blast sound levels corresponds to about a 2-dB increase in window acceleration levels in the mid-frequency range. This relative increase in window acceleration levels may account for the 2-dB increase in adjusted sound exposure level for a 1-dB increase in blast sound CSEL that is inherent in the high-energy impulsive sound assessment methods contained in the new ANSI Standard of 1996.

AN - 79732210; 9497356 AB - Saccharomyces cerevisiae RAD7 and RAD16 genes function together in the nucleotide excision repair of transcriptionally inactive DNA. The RAD7- and RAD16-encoded proteins exist as a tight complex named nucleotide excision repair factor 4 or NEF4. Previously, we showed that NEF4 binds UV-damaged DNA with high specificity and with a dependence upon ATP and that inclusion of NEF4 to the reconstituted nucleotide excision repair system consisting of purified NEF1, NEF2, NEF3, and replication protein A results in marked stimulation of damage-specific DNA incision. Here we show that NEF4 possesses an ATPase activity that is entirely dependent on a DNA cofactor and that double-stranded DNA is twice as effective as single-stranded DNA in activating ATP hydrolysis. Even though DNA binding is promoted by the nonhydrolyzable ATP analogue adenosine 5'-O-(thiotriphosphate) (ATPgammaS), damage binding is more proficient with ATP than with ATPgammaS. Interestingly, UV irradiation of double-stranded DNA results in a pronounced attenuation of the ATPase activity. Taken together, our results suggest a model in which ATP hydrolysis by NEF4 fuels the translocation of NEF4 on DNA in search of UV lesions and damage binding by NEF4 leads to a down-regulation of the ATPase activity. Damage-bound NEF4 could then serve as a nucleation point for the assembly of other repair components.

AN - 79811486; 9553878 AB - A secure bond between resin and an alloy framework is necessary for clinical success in removable prosthodontics. This study compared the shear bond strength of composite to composite to metal with two commercially available chemical bonding systems: a silicoating system (Silicoater) and a nitrogenous heterocycle-acrylonitrile system (Kevloc). Fifty-two nickel-chromium cubes were cast and composite resin was bonded to the alloy surfaces according to manufacturer's directions. After storage at 35 degrees C for 15 days, and thermocycling at 5 degrees C and 55 degrees C for 1200 cycles, the bonds were fractured in shear on a universal testing machine. Mean bond strength for the silicoated sample was 10.93 MPa and for the heterocycle-acrylnitrate system 11.44 MPa. An unpaired t test revealed no difference between the groups (p = 0.60). Visual inspection of the fracture surfaces revealed that failure was adhesive at the resin-to-metal surface in almost all the specimens.

AN - 79756433; 9525290 AB - AP-endonuclease (APE) plays a central role in the base excision repair process for oxidative and alkylation damage in DNA. The major human APE with 318 amino acid residues possesses transcriptional regulatory activities for which the N-terminal region was found to be essential. Systematic deletion studies of both amino and carboxyl termini of the human APE have shown that the carboxyl termini residues are essential for the endonuclease activity as indicated by direct measurement of enzyme activity and from studies on phenotypic rescue of Escherichia coli. However, the amino-terminal residues are dispensable for this activity and the boundary of the active endonuclease lies at this end between positions 61 and 80.

AN - 79727160; 9500444 AB - The environmental carcinogen benzo(a)pyrene-7,8-diol-9,10-epoxide (BPDE) forms DNA adducts with unique stereochemistries that may have divergent biological fates, depending on how they are processed within a cell. To investigate the effect of DNA bulky adduct stereoisomerism on the mutagenic outcome of translesion DNA replication in a human cell extract, oligonucleotides were synthesized that contained (+)- and (-)-anti-cis-BPDE enantiomers on N6 adenine at position 2 of the human N-ras 61 codon. Both the nonadducted and BPDE-adducted oligonucleotides were introduced into two double-stranded vectors, replicative forms M13mp2SVoriL and M13mp2SVoriR, which contain SV40 origins of replication in two different orientations relative to the adduct insertion site. Nonadducted and adduct-containing vector DNA constructs were replicated in HeLa cytoplasmic extracts and then screened in bacteria for base substitutions at the adduct site. The mutation frequencies for the adducted DNAs were at least 10 times higher than for the nonadducted DNA and ranged from 5.5 x 10(-4) to 1.5 x 10(-3). The (-)anti-cis enantiomer was more than twice as mutagenic as the (+)-enantiomer. All three possible base mutations were present, with the A-->G being the predominant one. No dramatic differences in replication fidelity were found when the adducts were placed on the leading versus the lagging strand of the vector.

Over time, the seasonal shrinking and swelling may result in sloughing and shallow slides. One possible solution to this problem is the inclusion of randomly distributed short fibers in the clay. The purpose of the research presented herein was to assess the feasibility of using commercially available short fibers to reduce the development of desiccation cracks in clay. The test results showed that the fibers were effective in reducing the amount of desiccation cracking that occurred in clays subjected to drying. However, when subjected to wet/dry cycles attempting to simulate environmental conditions, the effectiveness of the fibers was not as evident. The inclusion of fibers increased the tensile strength of the clay and provided a ductile behavior that was not present in the samples without fibers.

Infection was induced by inhalation of aerosolized Yersinia pestis organisms. Antibiotics were administered by intraperitoneal injection every 6 hours for 5 days, at doses that produced levels of drug in serum comparable to those observed in humans treated for other serious infections. These studies compared in vitro to in vivo activity and evaluated the efficacy of antibiotics started at different times after exposure. Early treatment (started 24 h after challenge, when 0 of 10 mice tested had positive blood cultures) with netilmicin, ciprofloxacin, ofloxacin, ceftriaxone, ceftazidime, aztreonam, ampicillin, and rifampin (but not cefazolin, cefotetan, or ceftizoxime) demonstrated efficacy comparable to streptomycin. Late treatment (started 42 h after exposure, when five of five mice tested had positive blood cultures) with netilmicin, ciprofloxacin, ofloxacin, and a high dose (20 mg/kg of body weight every 6 h) of gentamicin produced survival rates comparable to that with streptomycin, while all of the beta-lactam antibiotics (cefazolin, cefotetan, ceftriaxone, ceftazidime, aztreonam, and ampicillin) and rifampin were significantly inferior to streptomycin. In fact, all groups of mice treated late with beta-lactam antibiotics experienced accelerated mortality rates compared to normal-saline-treated control mice. These studies indicate that netilmicin, gentamicin, ciprofloxacin, and ofloxacin may be alternatives for the treatment of pneumonic plague in humans. However, the beta-lactam antibiotics are not recommended, based upon poor efficacy in this mouse model of pneumonic plague, particularly when pneumonic plague may be associated with bacteremia.

In animal models, it inhibits the early host inflammatory response to infection which is associated with decreased blood and tissue levels of proinflammatory cytokine synthesis. To elucidate further the pathogenetic mechanism(s) of V, in vitro systems are needed to measure and analyse relevant functional activities of V. We studied the effect of V on the migration of neutrophils to a chemoattractant both in vivo and in vitro. Peripheral injection of V was associated with a reduction in the number of PMN migrating into s.c. sponges and i.p. exudates. Similarly, pre-incubating human peripheral blood neutrophils with greater than or equal to 1 ng/ml V significantly inhibited the in vitro chemotactic response to the peptide chemoattractant FMLP. The inhibitory activity of V was inactivated by heat and was neutralized by rabbit polyclonal anti-V IgG as well as by sera from mice surviving infection with Y. pestis. Recombinant polyhistidine-tagged V fusion proteins retained biological activity compared to V proteins lacking the tag. Inhibition of chemotaxis appears to be the first demonstration of an in vitro biological effect of V and may be a useful model to elucidate its molecular mechanism of action.

AN - 79702028; 9486816 AB - Cancer patients treated with the anticancer drug, paclitaxel (Taxol) often experience mild to severe hypersensitivity reactions. It is not known how these reactions are induced and whether the inducer is paclitaxel or its vehicle (i.e., Cremophor EL in 50% ethanol). Molecules present in Cremophor EL are similar in structure to certain nonionic block copolymers that activate complement proteins (i.e., proteins involved in various immune processes). To explore the role of complement in the observed hypersensitivity reactions, we studied the effects of paclitaxel and Cremophor EL plus ethanol on human complement in vitro. Serum specimens from healthy individuals and cancer patients were incubated with paclitaxel or with relevant control compounds (Cremophor EL with ethanol, ethanol only, docetaxel, and cyclosporine), and markers of complement activation (SC5b-9 and Bb) were measured by enzyme-linked immunosorbent assay. Similar incubations were performed in the presence of inhibitors of complement activation (i.e., EGTA/Mg2+ and soluble complement receptor type 1 [sCR1]). Paclitaxel in Cremophor EL plus ethanol caused increased formation of SC5b-9 in serum specimens from 10 of 10 healthy control subjects and from five of 10 cancer patients. Experiments with one or more individual sera indicated the above effect was due to Cremophor EL plus ethanol, that increased formation of Bb also occurred, that the drug-induced rise in SC5b-9 was inhibited by sCR1, and that EGTA/Mg2+ partially inhibited SC5b-9 formation and stimulated Bb formation. The role of complement activation in hypersensitivity reactions associated with administration of paclitaxel in Cremophor EL plus ethanol should be studied in vivo.

AN - 79726949; 9504665 AB - N-methyl-2,2'-dichlorodiethylamine (HN2)is a topical chemotherapeutic agent used as therapy for cutaneous T-cell lymphomas (CTCL). Di(2-chloroethyl)sulfide (SM), and less often HN2, have been used as chemical weapons, with the skin being a principle target. The mechanisms by which these chemicals produce their therapeutic and toxic effects in skin, however, are not clearly defined. We exposed human skin explants to two doses of HN2 and SM. At 18 hours after exposure, histopathologic features were compared. In addition, immunohistochemical markers to basement membrane proteins were used to evaluate the effects of both chemicals on the basement membrane zone. Gross vesication was not seen. Pyknotic nuclei with or without dyskeratotic changes within epidermal keratinocytes were present at both doses. These changes varied more between skin specimens than they did between doses. Ballooning degeneration was more marked after SM exposures. Diffuse dermal-epidermal separation was present only at high-dose exposures and did not appear to correlate with the degree of changes locally in the overlying epidermis. Antibodies to laminin-5 showed decreased immunoreactivity after exposure to HN2 and SM. Immunoreactivity for laminin- was decreased to a lesser extent, and immunoreactivity for collagen IV and VII was unchanged. HN2 and SM produce similar histopathologic and immunohistochemical features after cutaneous exposure. These features suggest that part of mechanism of action of HN2 and SM is a direct effect on the basement membrane zone. Understanding the effects of HN2 and SM separate from their effect on DNA may be important in designing therapies and in advancing our understanding of the pathophysiologic changes induced by these chemicals when delivered topically.

However, whether environmental safety is improved by composting can be determined only by assessing the effects of the treated material on living organisms. In this study two bioassays, the Mutatox assay and the earthworm acute toxicity test, were used to evaluate the effectiveness of a pilotscale composting demonstration in reducing environmental hazard. Explosive-contaminated soil was collected from a military installation and amended for composting in two adiabatic reactors. The unamended soil was lethal to all exposed earthworms, as were both amended replicates, prior to composting. Serial dilutions of the finished composts with artificial soil had earthworm 14-day LC sub(50) values of 35.7 and 100% finished compost: artificial soil. Extracts of the initial materials were also toxic to bacteria in the Mutatox assay. Dilutions of those extracts to sublethal concentrations revealed a low level of mutagenicity. Extras of the finished composts indicated reduced bacterial toxicity, but the mutagenicity was markedly increased by composting. The reduction in lethality reflected the attenuation of explosives caused by composting, as indicated by chemical analysis. However, the increased mutagenicity was a result that would not have been indicated by chemical analysis alone and is inferred to be the result of the formation of mutagenic metabolites of explosives during composting and their incomplete degradation.

The two domains are of nearly equal size and are connected by a hinge region. The Ada protein accepts stoichiometrically the alkyl group from O super(6)-alkylguanine in DNA at the Cys-321 residue and from alkyl phosphotriester at the Cys-69 residue. This protein functions in DNA repair by direct dealkylation of mutagenic O super(6)-alkylguanine. The protein methylated at Cys-69 becomes a transcriptional activator of the genes in the ada regulon, including its own. Each of the two domains functions independently as an alkyl acceptor. The purified homogeneous protein is unstable at 37 degree C and spontaneously loses about 30% of its secondary structure in less than 30 min concomitant with a complete loss of activity. However, sedimentation equilibrium studies indicated that the inactive protein remains in the monomeric form without aggregation. Furthermore, electrospray mass spectroscopic analysis indicated the absence of oxidation of the inactive protein. This temperature-dependent inactivation of the Ada protein is inhibited by DNA. In the presence of increasing concentrations of urea or guanidine, the protein gradually loses more than 80% of its structure. The two alkyl acceptor activities appear to be differentially sensitive to unfolding and the phosphotriester methyltransferase activity is resistant to 7 M urea. The partial or complete unfolding induced by urea or guanidine is completely reversed within seconds by removal of the denaturant. The heat-coagulated protein can also be restored to full activity by cycling it through treatment with 8 M urea or 6 M guanidine. These results suggest that the nascent or unfolded Ada polypeptide folds to a metastable form which is active and that the thermodynamically stable structure is partially unfolded and inactive.

The presence of linear B-cell epitopes in the V protein was investigated by using a series of 17 overlapping linear peptides. Groups of 10 mice were immunized intraperitoneally with 30 mu g of each peptide on days 0, 30, and 60. Although the V protein-specific antibody response to the peptides varied, most of the peptides elicited high antibody titers. The immunized mice were challenged subcutaneously with 60 50% lethal doses (LD sub(50)) (1 LD sub(50) = 1.9 CFU) of a virulent Y. pestis strain, CO92. None of the peptide-immunized mice survived challenge. The animals immunized with the V protein were completely protected against challenge. The immunogenicity of some of the V peptides was increased by conjugating them to keyhole limpet hemocyanin. Only one peptide (encompassing amino acids 1 to 30) conjugate demonstrated some protection; the others were not protective. In additional experiments, V peptides that reacted well with sera from mice surviving Y. pestis infection were combined and used to immunize mice. Although the combined peptides appeared to be very immunogenic, they were not protective. Therefore, the protective B-lymphocyte epitope(s) in the V protein is most likely to be conformational.

The biological activities of IL-1 receptor antagonist (IL-1ra) or IL-1ra-like molecule were measured by its ability to suppress the IL-1 beta -mediated induction of adhesion molecules (ICAM and ELAM) on EC and of IL-6 secretion by these cells. Two different, purified, immunogenic and biologically active preparations of F1, at concentrations up to 10-fold higher than that of IL-1ra, did not exhibit any inhibitory activities of IL-1ra. These F1 preparations also did not activate peripheral blood mononuclear cells to produce IL-4 or IL-10, cytokines which might downregulate pro-inflammatory cytokine production in response to infection. Thus, even though there is a high degree of similarity between F1 antigen and IL-1ra in three-dimensional structure by computer modeling and sequence homology, our work indicates that F1 antigen of Y. pestis does not have IL-1ra-like activity.

Just as cerebral malaria results from parasite sequestration in the brain, maternal malaria results from parasite sequestration in the placenta, and a distinct subpopulation of parasites which bind chondroitin sulfate A but not CD36 causes the syndrome. Women have little or no immunological experience with this parasite prior to first pregnancy, making primigravid women particularly vulnerable to infection. Parasites adhere to the surface of trophoblastic villi, eliciting the accumulation of inflammatory leukocytes in the intervillous space, and the necrosis of adjacent placental tissue. Maternal malaria results in poor pregnancy outcomes, although the responsible mechanisms have not been defined. In holoendemic areas both placental infection and poor outcome decrease in frequency with successive pregnancies; protection may result from control of parasite adhesion, suggesting an attractive target for new therapies.

During a field experiment at Barrow, Alaska, we examined the horizontal variability of spectral albedo and transmittance as well as the vertical variability of in-ice radiance. Temporal changes were monitored under cold conditions in April and during the onset of melt in June. Physical properties, including ice structure and concentrations of particulate and dissolved material, were measured to provide a context for understanding the observed temporal, horizontal, vertical, and spectral variability in optical properties. For snow-covered first-year ice in April, wavelength-integrated (300-3000 nm) albedos were high (0.8) and spatially uniform, but there was considerable variability in transmittance. Transmittance at 440 nm ranged by more than a factor of 2 over horizontal distances of only 25 m, owing primarily to differences in snow depth, although spectral variations in transmittance indicate that absorbing organic materials in the ice column contribute significantly to the horizontal variability. Peak values of transmittance in April were 1% near 500 nm, decreasing at both longer and shorter wavelengths. At the onset of melt in June, the ice surface rapidly evolved into a variegated mixture of melting snow, bare ice, and melt ponds. JF - Journal of Geophysical Research. C.

AN - 79655045; 9425080 AB - N-Methylpurine-DNA glycosylase (MPG), a ubiquitous DNA repair enzyme, is responsible for the removal of a wide variety of alkylated base lesions in DNA, e.g., N-alkylpurines and cyclic ethenoadducts of adenine, guanine, and cytosine. These lesions, some of which are mutagenic and toxic, are generated endogenously or by genotoxic agents such as N-alkylnitrosamines and vinyl chloride. Wild-type mouse MPG, expressed from recombinant baculovirus, was purified to near homogeneity for studying its specific interaction with substrate, 1,N6-ethenoadenine- (epsilonA-) containing DNA. Electrophoretic mobility shift assays (EMSA) indicated that MPG formed a specific complex with a 50-mer epsilonA-containing duplex oligonucleotide. This complex was shown to be a transient reaction intermediate, because it could be formed only with the unreacted substrate and contained active enzyme molecules. DNA footprinting studies confirmed the specific binding of the protein to the epsilonA-containing duplex oligonucleotide; eight nucleotides on the epsilonA-containing strand and 16-17 nucleotides in the complementary strand spanning the base adduct were protected from DNase I digestion. A systematic deletion analysis of MPG was carried out in order to determine the minimally sized polypeptide capable of forming a stable substrate complex that is also suitable for characterization by NMR spectroscopy and X-ray crystallography. A truncated polypeptide (NDelta100CDelta18) lacking 100 and 18 amino acid residues from the amino and carboxyl termini, respectively, was found to be the minimal size that retained activity. The truncated and wild-type enzymes have similar kinetic properties. Moreover, both EMSA and DNase I footprinting studies indicated identical pattern of specific binding by the truncated and full-length polypeptides. Removal of five and nine additional residues from the amino- and carboxyl-termini of this polypeptide, respectively, resulted in a complete loss of activity. These results suggest that minimal structural change occured as a result of truncation in the NDelta100CDelta18 mutant, which may thus be suitable for elucidating the structure and mechanism of MPG.

AN - 79653543; 9425044 AB - Organophosphorus acid anhydride (OP) "nerve agents" are rapid, stoichiometric, and essentially irreversible inhibitors of serine hydrolases. By placing a His near the oxyanion hole of human butyrylcholinesterase (BChE), we made an esterase (G117H) that catalyzed the hydrolysis of several OP, including sarin and VX [Millard et al. (1995) Biochemistry 34, 15925-15930]. G117H was limited, however, because it was irreversibly inhibited by pinacolyl methylphosphonofluoridate (soman); soman is among the most toxic synthetic poisons known. This limitation of G117H has been overcome by a new BChE (G117H/E197Q) that combines two engineered features: spontaneous dephosphonylation and slow aging (dealkylation). G117H/E197Q was compared with the single mutants BChE G117H and E197Q. Each retained cholinesterase activity with butyrylthiocholine as substrate, although kcat/Km decreased 11-, 11- or 110-fold for purified G117H, E197Q, or G117H/E197Q, respectively, as compared with wild-type BChE. Only G117H/E197Q catalyzed soman hydrolysis; all four soman stereoisomers as well as sarin and VX were substrates. Phosphonylation and dephosphonylation reactions were stereospecific. Double mutant thermodynamic cycles suggested that the effects of the His and Gln substitutions on phosphonylation were additive for PSCR or PRCR soman, but were cooperative for the PSCS stereoisomer. Dephosphonylation limited overall OP hydrolysis with apparent rate constants of 0.006, 0.077, and 0.128 min-1 for the PR/SCR, PSCS, and PRCS soman stereoisomers, respectively, at pH 7.5, 25 degrees C. We conclude that synergistic protein design converted an archetypal "irreversible inhibitor" into a slow substrate for the target enzyme.

The UWB pulses (101-104 kV/m, 1.0 ns width, 165 ps rise time) were applied at the repetition rates of 0 Hz (sham), 16 Hz, or 600 Hz. The effect of exposures was evaluated from the colony-forming ability of the cells on complete and selective media and the number of aberrant colonies. The experiments established no effect of UWB exposure on the UV-induced reciprocal and non-reciprocal recombination, mutagenesis, or cell survival.

AN - 79712924; 9493172 AB - Turnover of [3H]phosphoinositides (PI) was examined in brain slices from the hippocampus of rats undergoing soman-induced seizure activity. Hydrolysis of PI was determined by measuring the accumulation of [3H]inositol-1-phosphate (IP1). Incubation of hippocampal slices in the presence of carbachol or norepinephrine (NE) increased PI hydrolysis. Stimulated hydrolysis by NE, but not carbachol was significantly reduced in slices from soman-challenged rats undergoing convulsive activity. NE-stimulated PI hydrolysis was not reduced in slices from animals exposed to soman that did not exhibit convulsive activity. In rats surviving for 24 h, the response to NE was not different from control rats. In control slices, NE-stimulated hydrolysis of PI was potentiated by GABA. No potentiation by GABA was seen in slices from animals undergoing seizures. Uptake and incorporation of myo-[2-3H]inositol into phospholipids was reduced in slices from rats undergoing convulsions. Reduced IP1 production appeared to be owing, in part, to decreased synthesis of inositol lipids. These observations suggest that during soman-induced seizure activity, there is an apparent decrease in the response of the PI second messenger system to NE stimulation, and that this may contribute to the severity and duration of convulsions and brain damage resulting from exposure to soman and other anticholinesterase compounds.

AN - 79664949; 9449602 AB - Although heparin is widely used as the injectable anticoagulant of choice, it has several potential shortcomings. These include heparin resistance, excessive bleeding, allergic reactions, and, with longterm use, occasional osteoporosis or alopecia. Perhaps the most notorious complication is heparin-induced thrombocytopenia and thrombosis (HITT); although unusual, it often results in major morbidity or death. Until recently, reliable diagnostic tests and anticoagulation alternatives have not been widely available. After a review of the pharmacology of heparin and related drugs, advances in the prevention, diagnosis, and treatment of this problem are discussed.

AN - 73903678; 9736485 AB - The mechanism of vesication from sulfur mustard remains unknown in spite of 80 years of investigation. We recently reported sulfur mustard-related inhibition of one or more protein (serine/threonine) phosphatases in tissue cytosol in vitro, suggesting a mechanism common to other vesicants such as cantharidin and Lewisite. Our investigation showed that this inhibition was related to the concentration of 2,2'-thiobis-ethanol (thiodiglycol), the hydrolysis product of sulfur mustard, rather than to the concentration of mustard itself. Related work showed an increase in the rate of NAD (but not NADP) reduction upon the addition of thiodiglycol to mouse liver cytosol. This result provided evidence that metabolism beyond thiodiglycol may be contributing to protein phosphatase inhibition. This observation indicated that metabolism involving one or more dehydrogenases may be necessary to produce the ultimate inhibitor of the protein phosphatases. We report here that thiodiglycol is a substrate for horse liver alcohol dehydrogenase (Km = 3.68+/-0.45 mM and Vmax = 0.22 +/-0.01 micromol min(-1) mg protein(-1)) and for pyridine nucleotide-linked enzymes in mouse liver and human skin cytosol. The alcohol dehydrogenase-specific inhibitor 4-methylpyrazole inhibited the oxidation of thiodiglycol by the pure horse liver enzyme as well as by the enzymes in human skin and mouse liver cytosol, indicating that the activity in the tissue preparations is also alcohol dehydrogenase.

AN - 70072545; 9825417 AB - To compare the tobacco use profile of recruits with that of military personnel on active duty to determine whether the military environment in some way induces service members to initiate tobacco use. Cross-sectional survey of United States armed forces active duty and recruit personnel in 1994-95. 2711 military recruits and 4603 military personnel on active duty. Comparative cigarette smoking and smokeless tobacco use prevalence between recruits and personnel on active duty controlling for age, sex, and race. Impact of demographic factors on the odds of smoking or using smokeless tobacco. Increases in tobacco use in American military personnel occurred exclusively in men. The highest tobacco use resided with white men on active duty (43% cigarette smoking; 24% smokeless tobacco use) and represents a doubling of tobacco use seen among white male recruits. Among non-white men, tobacco use increased 2-4 times between recruits and personnel on active duty. Efforts to reduce tobacco use by American military personnel on active duty should focus more on discouraging the initiation of tobacco use.

AN - 69198089; 10212896 AB - The critical decisions of which artemisinin derivative(s) to use and by which route(s) of administration for falciparum malaria are complex scientifically and politically. Despite the need for additional pharmacokinetic, pharmacodynamic and toxicokinetic data, these drugs are too important to delay concise, rational recommendations any longer. These types of decisions must be made now, implemented on a multinational level with WHO leadership, and revised as new findings emerge. For acute, uncomplicated disease, per os dosing of artesunate or artemether for three days is recommended, but only in combination with other antimalarial drugs like mefloquine. For severe falciparum malaria, intravenous administration is the preferred route, yet current formulations for intravenous dosing are not optimal and should be an area for future development emphasis. Clearly intramuscular administration of artemether has proven effective for severe disease, yet dosing regimens shouldn't be designed with ultimate parasitological cure as the aim and the problem of bioavailability of the sesame oil formulations must be examined further. Once the life-saving reduction in parasitemia and pathophysiological sequelae have been achieved, the patient can be given oral medication to affect radical cure. Much more data will be required to define the role of per rectum dosing for the treatment of severe malaria, yet this approach holds great promise as a life-saving intervention in rural areas where this disease has it most dramatic impact.

AN - 69193361; 10212893 AB - The discovery of the occult brainstem neurotoxicity subsequent to widespread deployment of artemisinin derivatives has created particular problems. That is, the clinical setting for artemisinin use is problematic for accomplishing what ordinarily would be addressed in phase I-II clinical trials. Nevertheless, it is clear that an urgent and vital need exists for the deployment and widespread availability of artemisinins. The work done to date has already yielded a substantial body of evidence that, while incomplete, provides guidelines for artemisinin use to minimize the risk of these drugs while preserving their much-needed efficacy. The evidence thus far shows that route of administration, oil/water solubility and concentration-duration of drug level, are critical determinants of toxicity and can be given appropriate consideration in the clinical decisions regarding route, choice of drug used, and drug regimens. In this regard, an oral, water-soluble drug with moderately rapid clearance may be the most attractive choice in the absence of significant differences in efficacy. The same body of evidence clearly shows that toxicity can, and does, develop with no obvious or useful clinical marker. Therefore, the development and validation of a test that can reliably detect the onset of injury, at a reversible stage, is a critical path task for any future development in this class. More complete understanding of mechanisms, kinetics, and molecular targets of neurotoxicity, will certainly be forthcoming. A continuing, more generalized use of these drugs, however, cannot be fully endorsed without a useful, practical clinical test of toxicity. The requirement is especially critical in light of the reality that those patients receiving artemisinin derivatives live in high risk environments and are likely to receive repeated courses of therapy with little likelihood of close, post marketing surveillance.

T2 - International Sociological Association AN - 61783742; 98S33639 AB - Suggests that the construct of morale remains with sociologists, perhaps like the proverbial "tar baby." It is argued that "morale," despite confusion about its meaning & measurement, is still a useful construct for both social scientists & laypersons. Morale has special (though not exclusive) relevance in military organizations. It is an apparent universal, found in some form in the parlance of military organizations of all countries. It is thus a special responsibility of sociologists & psychologists working with military organizations to address the construct of morale &, by applying the tools of science, bring increased utility & clarity to the subject. Following a brief exposition of conceptual issues, a simplified measurement strategy is suggested. Data from several studies are offered in support of this approach.

While these measures proved to be intercorrelated, they appeared to be measuring different phenomena. Not only were personal morale means higher than those for the company measure & displayed less variance when aggregated at the company level, but in factor analyses & path-analytic models, they showed correlational & predictive patterns that indicated associations with measures of self-esteem & psychological well-being, rather than measures of social solidarity & cohesion, which were better linked to the company measure. It is concluded that, while a deductive approach has certain merits with respect to theory building, for empirical studies it is best to focus on the everyday use of such terms as morale whether referring to individuals or groups.

All these impacts directly affect soil erodibility and runoff erosivity. Our objective was to measure the effects of soil freeze-thaw (FT) cycling on compacted soil in vehicle ruts and on the geometry of ruts and natural rills. We established research sites at Yakima Training Center (YTC) in south-central Washington in December 1995 and at Ethan Allen Firing Range (EAFR) in northwestern Vermont in October 1996. The mean length of the freezing season at YTC is 50-60 days and at EAFR, 110-120 days. Observations over one winter at YTC show that: 1) tank-rut profiles smoothed as sediment from rut crests slid into the rut; 2) mean penetration resistance and bulk density below 5 cm deep in ruts were statistically higher than out of ruts, especially when the soil contained 15% water by volume during tracking; 3) saturated hydraulic conductivity was lower in 75% of straight ruts made on soil with 15% water, lower yet in turning ruts, and not statistically different in and out of ruts when tracking on soil with 5% water; and 4) surface-water runoff began sooner and runoff rates were 67-77% higher in ruts than on adjacent, unrutted soil due to decreased infiltration in ruts. EAFR observations showed that: 1) incipient rills and a distinct v-shaped, 11-cm-deep rill formed in ruts, while adjacent, untrafficked soils showed no rill initiation; 2) scattered sidewall slumps occurred along deeper rills during spring thaw; and 3) unconfined compressive strength of the surface soil in tank ruts decreased by 60%, in wheel paths by 50% and in untrafficked soil by 29% due to soil FT cycling. These results will be useful in parameterizing soil-erosion models for use by land managers of military training lands in cold regions.

For example, predicted joint spacing in simulated horizontal boreholes, 0.17 cm, is about 25 percent less than mean measured vertical joint spacing in the Analogue Area. All predictions are within the standard deviations of field measurements and generally within the range of measurements made in the four field areas. Most are within 25 percent of field measurements in the Analogue Area. The accuracy of predictions was assessed by selecting one of the field areas as a denied area, and using the same procedures to make predictions for the same variables These predictions are within 10 to 15 percent of the field measurements: predicted mean joint spacing in simulated horizontal boreholes, for example, is 0.21 cm and mean measured vertical joint spacing is 0.22 cm. This indicates that predictions made using these procedures are accurate as well as realistic. Additional work in other areas will determine the general applicability of these procedures and the model developed.

The questions of landscape stability and sustainability were tested at Fort Leonard Wood, Missouri. The military reservation was selected because it has been the site of engineering training for over 5 decades. Prior to US Army land-use, the landscape was undergoing disequilibrium resulting from historic land-use activities. Landscape changes were examined using an integrated approach. Available information and technologies were applied to answer geomorphic inquiries of equilibrium and recovery. Accepted soil-loss equations were used to back calculate sediment loads over decade time-scales. Modern sediment studies offered calibration rates for specific events. Estimated annual sediment yields were used to validate soil-loss equations. Soil-loss simulations suggested that the sediment load increased sharply in response to historic land-use change between 1800 and 1938. Increased rates continued during the first few decades of US Army ownership. Current conservation practices have reduced the rate of soil loss and the landscape seems to be in recovery. Time-series simulations of RUSLE reveal a reduction in soil-loss over the last decade. The values derived from the soil-loss simulations and studies still leave uncertainty due to variability in the geomorphic system. To supplement simulations, oral histories inquired about twenty century land use and erosional processes. Many informants agreed that the land is reaching a stable state. Collectively, the several lines of evidence when viewed synoptically suggest that the landscape is healing from past stresses. This study supports the US Army's commitment that landscape stewardship is essential for land-use sustainability.

Maintenance of these roads is critical for mission readiness, and the safety of soldiers, civilians, and machinery, but can be expensive. WES is developing a road management plan to strategically use available funds for re-engineering and planning a maintenance schedule for the unsurfaced range-road network. UMR GE students conducted the road survey. The team created a systematic method for field inspection, data collection, and evaluation while applying the U. S. Army Corps of Engineer's Rating Unsurfaced Roads procedure. Seven distresses--improper cross-section, inadequate drainage, corrugations, dust, potholes, ruts, and loose aggregate--were measured. An unsurfaced road condition index (URCI) was calculated based on the seven distress ratings. The unsurfaced roads ranged in condition from poor to excellent. This data was transposed into a database and linked to a Geographic Information System (GIS). The resulting GIS data was used to display problem reaches and corresponding distresses. One problem is that the roads were designed for lower loads and volume of traffic. Therefore, heavy-loaded roads will require improved design such as additional aggregate. Local sources of aggregate include river chert gravel or quarried crushed dolomite. Alternative engineering solutions are being considered. For example, lime treatment of the natural subgrades will increase the CBR and thereby reduce the thickness of needed aggregate. Other engineering, such as drainage rerouting, will lower long term maintenance costs. With the help of GPS/GIS technology, and the fieldwork inspection information, decisions can be made to upgrade FLW' roads into better service level for the future training.

A regional geologic approach addresses the needs of the facility and places it in the larger framework of the land, water, and people off post that comprise potential contaminant receptors. Application of a regional geologic framework to a large military facility can require extensive research and focused study to establish the regional picture. As an example, a geologic and geomorphic model was developed for the Aberdeen Proving Ground (APG), located in the headwaters of Chesapeake Bay, Aberdeen, MD. Available regional geologic data and interpretation of boring data from over two thousand geologic and water well borings indicate that APG is situated upon Pleistocene Susquehanna River terraces unconformably overlying Cretaceous sediments. Pleistocene terraces represent estuarine and fluvial filling of an earlier Chesapeake Bay by the Susquehanna River during high sea level or interglacial periods. During low sea level periods, corresponding to glacial maxima, the Susquehanna River downcut into Pleistocene and Cretaceous sediments. Present at the APG are the remnants of at least three and possibly four separate filling cycles, designated from youngest to oldest as QT1 (Middle Wisconsin), QT2a (Sangamon), QT2b (Middle Pleistocene) and QT3 (Early Pleistocene?). The geologic and geomorphic model of APG is being used to define aquifer limits and to assess the movement of ground water for impacts to public drinking water supplies and Chesapeake Bay.

This effort is not a compilation of previous work but is instead an attempt to create a regionally uniform GIS whose accuracy and precision is known and verified; the digital form of the GIS also allows for rapid changes in the product as new information is obtained. The mapped area covers >250,000 km (super 2) and includes parts of California, Nevada, Arizona, and Utah. The mapping base passes national map accuracy standards at 1:24,000; the GIS contains approximately 60,000 polygons, with a MMU of 10 hectares. The timeframe for completion is four years. The final products will include a digital GIS, hard copy maps (1:100,000), and a website that describes the methodology used in mapping, definitions of mapping units, and practical implications of the data. One of the central themes of the project is to create a product that can be effectively used and understood by geologists and non-specialists alike. The GIS is intended to impact a wide range of public and private sector functions including: 1) decision-support for DOD and DOI land managers; 2) hypothesis construction and testing by research scientists (e.g., the anatomy of an ecosystem, the relationship between tectonics and landscape); 3) mineral exploration; 4) regional and local landuse planning; 5) education. Preliminary accuracy assessment analysis of completed areas shows that our methodology produces results that are better or equivalent to those created through conventional mapping methods.

A physically based numerical snow-transport model (SnowTran-3D) is developed and used to simulate this three-dimensional snow-depth evolution over topographically variable terrain. The mass-transport model includes processes related to vegetation snow-holding capacity, topographic modification of wind speeds, snow-cover shear strength, wind-induced surface-shear stress, snow transport resulting from saltation and suspension, snow accumulation and erosion, and sublimation of the blowing and drifting snow. The model simulates the cold-season evolution of snow-depth distribution when forced with inputs of vegetation type and topography, and atmospheric forcings of air temperature, humidity, wind speed and direction, and precipitation. Model outputs include the spatial and temporal evolution of snow depth resulting from variations in precipitation, saltation and suspension transport, and sublimation. Using 4 years of snow-depth distribution observations from the foothills north of the Brooks Range in Arctic Alaska, the model is found to simulate closely the observed snow-depth distribution patterns and the interannual variability.

The effect of vertical water movement on the rate of thaw and the thermal regime of the soil is quantified. An exact similarity solution only occurs when the vertical water velocity is proportional to the rate of thaw. This solution indicates that seepage flows (the magnitude of the water velocity is near that of the rate of thaw) have little effect upon the thaw process. Approximate solutions are also given for the case of constant water velocity, using the heat balance integral and quasi-steady methods; they agree with the exact solution if the Stefan number is not too large. Thaw can be greatly accelerated or retarded if the water velocity (Peclet number) is large. The effect upon thawing for the case of horizontal water flow is less than that for the same magnitude of vertical flow. JF - Collection Nordicana AU - Lunardini, Virgil J A2 - Lewkowicz, Antoni G.

The upper surfaces appear smooth, often show an ice layer, and vary in depth with channel bathymetry. Partial freezing within taliks appears to cause weak reflections from the talik surface, internal reflections, and a distorted talik radar image. The taliks shrink as they propagate downward through the winter. Some taliks completely freeze by mid-April. Others may exist at 3.7 m beneath a typical, 1.8-m-deep frozen channel, and deeper beneath channels that do not freeze completely. The persistent though diminishing flow from drill holes demonstrates their permeability.

Vegetation in the Flats consists of a mosaic of fen, birch forest, black spruce forest, shrub, and bog. Permafrost is not present in the fen and bog areas, but it exists on the bordering forested or shrub areas 0.5 to 2 m above water level. Our studies show that permafrost in the Flats is relatively warm at -0.2 to -0.7 degrees C, and that the distribution and characteristics of permafrost are related to the geobotanical conditions at a specific site. In general, permafrost is more ice rich and shows higher secondary porosity where finer-grained sediments (silts) are abundant. These are environments characterized by birch forest vegetation. Permafrost in areas of birch forest appears more susceptible to thaw and is currently showing signs of extensive degradation.

Roads, airfields, bridges, schools, hospitals, and water wells are constructed in remote areas with maximum use of local materials. Military geologists support construction by locating potential sources of aggregate, evaluating suitability of materials for road metal and fill, designing roadcuts, developing quarries, and evaluating geologic hazards that may affect the construction effort. In northern Honduras, excavation problems in a karstic limestone of the Mesozoic Yojoa Group delayed completion of a mountain road. Clay-filled solution cavities disrupted the blasting operation, jeopardizing the completion of the project. Geologists recommended rerouting the road through a rippable schist. Although longer, the new road was completed on time. In southern Honduras the lack of a suitable aggregate for a new airfield required a thorough geologic reconnaissance for new sources. Local ignimbrites were unsuitable due to their low compressive strength. Rhyolite and andesite from nearby volcanic erosional remnants were evaluated for their suitability. A quarry was subsequently developed and provided the aggregate needed to complete the project. In the Oriente of Ecuador a scarcity of suitable construction materials and unstable slopes created difficult conditions for a road and bridge construction project. Roadcuts into alternating layers of shale and limestone of the Cretaceous Lower Napo Formation created unstable slope conditions. Military geologists recommended new sources of aggregate and advised engineers on slope stability. Local construction methods were adopted to overcome these conditions.

Success in these endeavors relies on information about landform, structure, composition (rock and soil types), nature of the surface (sticky, dusty, hard, soft, etc.), and an evaluation of obstacles, engineering materials, water sources, and potential sites for ambush, defilade, and cover and concealment. Geology looms large. For many world areas, such information is not in the databases nor on maps; yet it is sometimes needed on short notice. The information can be derived from image analysis, and available imagery covers most of the world. Examples of such applications include Thule Air Base, Icecap access routes, Project Sanguine, Southeast Asia trafficability studies, and Operations Desert Shield/Storm. The Remote Sensing Field Guide--Desert, developed by a joint effort between the U.S. Army Topographic Engineering Center (TEC) and the U.S. Geological Survey, was used extensively in Operations Desert Shield/Storm in support of military operations. These materials plus spectral reflectance data are being blended into a hypermedia terrain database to support interactive image analysis between army elements.

S. Army AN - 52432189; 1999-066808 AB - The U.S. Army trains soldiers in geology under the guise of related topics. Thus, instructional responsibilities are disjointed. The army considers geologic matters to be the responsibility of Engineer officers. Familiarization of topographic requirements and construction practices, both military and civil, is given in the Engineer Officer Basic Course, with specific concepts included in the Engineer Officer Advanced Course. Officers wanting more depth in topographic matters take the Mapping, Charting, and Geodesy Officers Course that emphasizes terrain analysis. Enlisted personnel have more direct contact with geology. Construction materials specialists and quarry operations specialists receive instruction in rock identification and properties about quarrying and construction. On the topographic side, Basic Terrain Analysis teaches mineral and rock identification--weathering and soils are the targeted tasks. Sergeants learn more advanced geology concepts within an imagery analysis and interpretation block of classes in the Advanced Terrain Analysis Course. Warrant officers, normally selected from the enlisted ranks, provide technical expertise in terrain analysis. Although they receive no formal training, the competitive selection process generally chooses those with the most extensive computer knowledge and field experience in terrain analysis. Geology skills per se are not a criterion. The Topographic Engineering Center provides, when needed, a two-week intensive interdisciplinary imagery analysis and interpretation short course, which is primarily for federal agencies.

An understanding of subsurface fracture patterns is also essential for the field army with respect to penetrability and weapons effects. Many areas of the world in which the army has an interest are inaccessible (denied areas), and analysis of remotely sensed imagery provides a way to get needed information. This chapter describes a method that provides the basis for three-dimensional characterization of fracture patterns using remotely sensed imagery. Analysis of fracture patterns in the Dartmoor granite of southwest England shows that lineations delineated on imagery are very long, widely spaced joints that are members of joint sets found in outcrop. There are no statistically significant differences in orientation between joints and lineations; the smaller image scale allows the more widely spaced and longer members of a given joint set to be seen. With these relations established, fractal analysis of joint and lineation patterns on Dartmoor granite and in the East Pioneer Mountains, Montana, was done to determine whether fractal geometry could be used to predict subsurface fracture patterns. On Dartmoor, mean fractal dimension for vertical joint sets from outcrop and lineation patterns from imagery were comparable, but this was not the case for the Pioneer granites. Further research must address the problem of predicting three-dimensional, sub-surface fracture patterns using remotely sensed imagery prior to attempting to meet the needs of the field army in denied areas.

Military geology applications included locating potential quarry sites for sources of construction aggregate and fill, evaluating terrain features such as sabkhahs to assess cross-country mobility, and developing water sources. Sources of construction aggregate were needed to support sustainment engineering requirements in building and maintaining roads, heliports, and aircraft parking aprons in Saudi Arabia. Technical advice and assistance were provided to host nation forces who supported the production and transportation of aggregate from the source to the stock pile. Terrain analysis contributed to the success of the ground war. Obsolete or inaccurate maps were updated with new satellite images and field reconnaissance. Areas with inadequate terrain data were investigated to document natural as well as man-made obstacles. Coastal sabkhahs were evaluated and tested to determine their effect on mobility. Extensive surficial samples were collected for detailed geologic analysis, and field-expedient methods to improve trafficability were recommended. Military hydrogeologists and engineers worked closely with the Saudi Ministry of Agriculture to design and site new water wells. Several water wells were drilled by military teams to support operations deep in the desert. Satellite images, aerial photographs, maps, existing reports, and field reconnaissance were utilized to evaluate geologic conditions, thorough knowledge of which greatly contributed to the success of the ground war.

Many of these missions supported design requirements for Humanitarian Civic Action (HCA) wells but did not follow standard military water well construction practice. These design requirements have often been the result of local well construction regulations or the need for well yield that exceeded typical design. Each branch of our military has water well drilling capability, and most drilling systems are similar in depth and hole size ratings. Standard well completion kits for mobilization have been developed for construction of wells up to 455 m (1,500 ft) deep. Normal training for military well drillers has been limited, and the emphasis is on completion of a tactical, low-yield well where many potable well construction practices are not required. Humanitarian Civic Action well drilling missions have become an integral part of Nation Assistance exercises. Some HCA wells required special training, modifications to drilling equipment, and special well designs to meet the goals of the exercise. The probability of success had to be high for these missions to be approved. Consequently, civilian geologists were used to support the siting, well design, and procurement of materials. Some of these complex missions required on-site consultation. A specialized team of personnel including geologists, hydrogeologists, and geophysicists, designated the Water Detection Response Team, was assembled during the 1980s by the Corps of Engineers to site well drilling locations for military drilling operations and is used for many HCA missions.

These theories emphasize the roles of a) lateral grain sorting and b) local vertical sorting in producing overall downstream fining. The former produces fining through differential mobility of sediment patches with varying mean size; the latter produces fining by incorporating part of the coarse surface layer in the deposit. Laboratory experiments were conducted in a narrow channel (0.3 m) so that only the vertical-sorting mechanism could operate, using a mixture of 70% gravel and 30% sand. Deposits were produced with a prominent, sharp gravel-sand transition. The deposit upstream of this gravel front fined by about a factor of two in D (sub 90) over its length. A fourfold change in rate of deposition over three runs produced little change in the overall fining pattern. Experiments were also conducted in a wider channel (2.4 m) to allow lateral segregation to develop. The first test run showed weak lateral segregation and a fining pattern comparable to the narrow-channel runs although with somewhat weaker front development. In the second test run, the sand content of the feed mix was increased to about 50%. This produced well-developed patches and a continuous downstream fining pattern from gravel to sand with no clear front. This pattern is similar to that shown in field data collected from a rapidly aggrading reach of the North Fork Toutle River near Mt. St. Helens, Washington. These field data agree well with the lateral segregation fining theory, while the vertical-segregation theory shows good agreement with the results of the narrow-channel flume runs.

Since model calibration requires iteration and the integration of large volumes of data from multiple sources, model calibration can be one of the most expensive portions of a modeling study. A suite of tools is described in this paper which can significantly improve the efficiency of a calibration exercise. The tools are designed in a modular fashion and can be used for calibrating both finite difference and finite element models, in both two and three dimensions. Both point and flux observations are supported. Since the tools are implemented using GIS objects, observations may be associated with point, line, and area (polygonal) objects. A variety of graphical tools is included for plotting results and presenting statistical data associated with the calibration exercise. The calibration tools have been implemented in several hydroinformatics systems and have been applied to ground water, surface water, and watershed runoff models.

East Matagorda Bay is a large, shallow estuary acted upon by strong seasonal winds and by weather fronts in the fall and winter. A two-dimensional depth-averaged hydrodynamic model was applied to investigate the consequence of the presence of the SW Cut on the existing inlet, Mitchell's Cut, and on navigation safety in the Gulf Intracoastal Waterway (GIWW). This paper discusses the dynamic wind-generated motions measured in East Matagorda Bay as part of this study, calibration of the model over 30 days covering passage of several winter fronts, and predicted engineering consequences of opening the SW Cut. With the SW Cut in place, hydrodynamic conditions at Mitchell's Cut are predicted not to change, so that its natural stability will not be compromised. Also, a significant benefit will result through a predicted 25% decrease of peak current in a dangerous section of the GIWW due to flow captured by the SW Cut. JF - Estuarine and Coastal Modeling.

A recently developed model, referred to as CE-QUAL-ICM/TOXI, combines parts of two previously existing models to satisfy these needs. The transport framework of the eutrophication model, CE-QUAL-ICM, was combined with the toxic substance fate routines of EPA's WASP model. The result is an improved contaminant model that exhibits accurate transport capabilities with widely used fate process descriptions. Additionally, a benthic sediment module was formulated using variable numbers of layers and layer thicknesses to provide improved capabilities for simulating long-term benthic contaminant fate. The contaminant model is indirectly linked to a three-dimensional, hydrodynamic model, CH3D-WES, to drive the water column transport terms of the contaminant model. A dynamic solids balance for the water column and bed can be simulated within the model or read in from a sediment transport model, such as CH3D-COSED. For validation purposes, the model was applied to a flooded limestone quarry dosed with DDE. The model compared favorably against observed data and results from another simpler contaminant model. An application of the model to the New York-New Jersey harbor-estuary system for total PCBs is presented. JF - Estuarine and Coastal Modeling. Proceedings of the ...

A least squares spatial filter method is applied along a section of shoreline in Brevard County, Florida, U.S.A., to assist in assessing effects of a man-made navigation project upon adjacent downdrift shoreline. Results of application of the technique are discussed. Methods utilized by others for temporal and spatial smoothing of shoreline change are also noted.

These tests are conducted in the absence of wind, although strong onshore winds are typically associated with design storms. To study the effects of onshore winds on runup elevations, a series of physical model tests has been conducted in a combined wind/wave flume at Texas A&M University. Low wind speeds were seen to have little effect on runup elevations, but higher wind speeds significantly increased runup elevations on both smooth and rough slopes. Wind effects were greater on steep slopes than on shallow slopes, and greater on smooth slopes than on rough slopes. Various mechanisms by which wind may affect runup are discussed.

Sediment dynamics of mudbanks is known to be predominantly governed by waves, and suspended sediment concentration in this area is closely correlated to local entrainment and settling fluxes due to waves, which at times are modulated by effects of weak currents. A simple, semi-empirical model that accounts for the vertical fluxes of fine, cohesive sediment in water and across the water-fluid mud interface due to waves and a weak current has been formulated to simulate suspension concentration profiles. The model is initially tested against laboratory flume data on wave-induced entrainment of muds, which shows the importance of mud rheology in governing resuspension. The model is then used to simulate suspended sediment concentration profiles measured near the Alleppey Pier under monsoonal waves that create mudbanks close to shoreline. Profiles are generated to represent five documented stages of mudbank evolution from formation to dissipation. Because the field data are very sparse in terms of spatial and temporal coverage, only a limited comparison of model and field is achieved. In spite of this limitation, the exercise shows that it should be possible to obtain reasonably reliable site-specific results on predicted profiles of suspended sediment over mudbanks, provided adequate field data are available for selecting representative values of the empirical parameters for calibration of the model.

Often, aerial photographs and satellite images, after rectifying and georeferencing, serve as base maps to interpret landform changes and quantify shoreline movement. Large-scale topographic and hydrographic maps are the primary sources for shoreline position and volumetric change computations. Profile surveys, available from many Federal and local agencies and universities, can also be used to evaluate shoreline changes and compute beach volume changes along and across the shore. Frequently, post-processing steps are required to normalize these data to the same coordinate system and vertical datum prior to quantifying changes for a coastal area. For example, project-specific bathymetric data in the United States is often plotted using State Plane coordinates, while hydrographic data from NOAA is supplied with latitude/longitude coordinates. Maps, surveys, and aerial photographs are available from Federal agencies such as the USGS, NOAA, and the Corps of Engineers. These long-term data records can be used to evaluate natural and man-made changes to a coastal system. The resultant statistics and volumetric calculations should be presented in terms of the regional and local conditions, i.e., storm history, seasonality, wave climate, man-made environmental and engineering changes, and large- and small-scale landforms.

The measured total rates of longshore sediment transport were compared to predictions obtained with published empirical formulas, most of which have been calibrated mainly by sediment tracer measurements made on the (high-wave energy) Pacific coast. Transport rates measured in this study by the streamer sediment traps and the short-term impoundment along low-wave energy coasts were considerably lower than the rates predicted by empirical formulas. The empirical predictions appear to be unrealistically high for the low-wave energy settings investigated in this study. The linear relationship between wave energy flux factor and the total rate of longshore sediment transport contained in the commonly used CERC predictive formula is supported by the streamer trap measurements. However, a lower value of the empirical coefficient, 0.08 instead of the 0.78 recommended by the Shore Protection Manual, was determined by the trap data for low-energy coasts. The total rates of longshore sediment transport predicted by the Kamphuis (1991) formula which includes the influences of wave period, beach slope, and sediment grain size were about 3 times lower than the CERC predictions and closer to the measured values.

The evolution of the local reflection coefficient and the incident and total wave height is computed. Two initial conditions are needed; the incident H (sub rms) and the reflection coefficient, R, far offshore. The expected value of the wave breaking dissipation is estimated following Battjes and Janssen, (1978). The expected value of the reflected energy flux per unit area of beach profile is obtained hypothesizing that (1) wave reflection may be considered a linear process dependent only on the local profile geometry and wave period and (2) only the non-breaking waves contribute to the reflected flux of energy (Baquerizo, 1995). These results are compared with wave parameters measured during the SUPERTANK Project and with the reflection coefficient estimated by three different methods. Measured and computed data agree well for barred and non-barred beach profiles. It is shown that the local reflection coefficient evolves along the beach profile. An overall beach reflection coefficient should be defined only offshore of the depth where waves start to break and where the contribution to the wave reflection process is negligible.

Morgan was the examination of the structure, nature and origin of mudlumps. The origin of these features, which are virtually unique to the Mississippi River delta, had been the subject of much debate since they were first reported in 1528. Morgan and his colleagues concluded that they are small diapirs that have resulted from upthrusting of plastic clays in response to overloading by distributary mouth bar sands. These mudlump studies led to further research into sediment instability across the subaqueous delta of the Mississippi. This research, much of it conducted by Morgan's students, was greatly enhanced as the petroleum industry began to work in deeper water. Eventually side-scan sonar and high-resolution geophysical techniques were added showing the complicated nature of the subaqueous delta front. This paper summarizes the initial work of Morgan on sediment instability and mudlump formation and discusses the sediment instabilities that occur on the subaqueous delta front off the river mouths.

The basin is experiencing a number of challenges with respect to natural resources management issues both on and off the installation. These issues have prompted the Army to take a close look at the interaction between the Army and its regional neighbors over the next several decades. This will include identifying a broad range of alternative future scenarios that are possible within the basin. Through a Geographical Information System (GIS) evaluation effort, possible land use distributions which are most likely to develop as a result of each stated guiding scenario will be predicted. One of the tasks at this initial stage of the project is the assemblage of the GIS database to support the study.

AN - 51319973; 1999-049070 AB - The thawing of ice-rich permafrost beneath birch forests in the Tanana Flats area of Interior Alaska has produced thermokarst features colonized by a range of species and wetland vegetation types. As the forest drowns along its border with fens, an open-water moat is colonized by minerotrophic species and a floating mat develops. At the same time, thawing in the birch forest interior produces water-filled thaw pits and collapse scar bogs in which ombrotrophic vegetation develops through several stages to Sphagnum bogs. As the thawing front moves into the birch forest from the fen, these latter features are incorporated into the floating mat, accelerating the expansion of fens.

During this six-week study, ABS sorbed analytes much more rapidly and to a greater extent than did the other materials, and PVC and FRE sorbed analytes more slowly and to a lesser extent than the other materials tested. As the study progressed, an increasing number of spurious peaks were found in the high performance liquid chromatography chromatograms of some samples, indicating that leaching of some constituents had occurred. By the end of the study, there were 11 additional peaks in the ABS samples, five in the FRP samples, and one in the FRE samples. Analysis by purge and trap gas chromatography/mass spectrometry of those samples and of well water samples that were exposed to the casings for 500 hours revealed the identity of some of the leached constituents: acrylonitrile and styrene (components of ABS), chloroform and ethylbenzene (an intermediate in the production of styrene) from the ABS pipe, and toluene, 1,1,1-trichloroethane, and ethylbenzene from the FRP casing.

This research addresses the effects of soil freeze-thaw (FT) on rill and rut geometry, soil density, and infiltration, which partially determine water runoff quantity and velocity, and soil erodibility. Laboratory experiments and field observations showed that soil FT (a) decreased the channel hydraulic radius (R) of a rectangular rill and wheel ruts up to 33%, (b) increased infiltration in wheel ruts by 62%, (c) decreased unconfined compression strength and shear strength in wheel ruts up to 81% and 57%, respectively, and unconfined compression strength in track ruts on a 17 degrees slope during spring thaw, while uncompacted soil adjacent to that rut showed no evidence of rill formation. These results can be used in soil-erosion and terrain-evolution models to account for overwinter modifications to hillslope hydrology and soils.

This methodology includes ductile behavior of individual piles for the strength mode. It also examines the 3-D effects on the bounds for the series-parallel system. The procedure is an extension of the reliability method presented to compute the system probability of UP of pile-supported structures using brittle-element behavior. Lateral and vertical deflections are the limit states of the pile cap that provide the system-level probability of UP for the serviceability limit state. The element-level probability of UP for strength and system-level probability of UP for serviceability are combined to evaluate the bounds for the load-case specific system probability of UP. Finally, the overall system probability of UP is evaluated considering the contributions of all load cases combined. The procedure is illustrated with examples, and the bounds for the system probability of UP are evaluated. The results indicate that the bounds of probability of UP for the example are narrower for ductile behavior than for brittle behavior. A 3-D problem correctly recognizes a number of significant PM that are absent in the 2-D approximation.

While violence has and will continue around water, water is far more humanity's learning ground for building community than it is a cause of war. Increased interdependence through water sharing plans and infrastructure networks can be seen as increases of our flexibility and capacity to respond to exigencies of nature and reduce our vulnerability to events such as droughts and floods and thereby increase security. The history of social organization around river basins and watersheds is humanity's richest records of our dialogue with nature. It is among the most fertile areas for learning about how the political and technical interact. The spatial and functional characteristics of the river basins influenced human settlement and interaction long before the idea of the river basin started to be formalized into legal and administrative terms. The direction of flow of rivers influenced the movement of civilization. Rivers have been crucial to means of communication leading to the formation of political units. The article concludes with calling for new ethics in water management. It calls for an ethic built on: a sense of purpose and on an active co-designing with nature and not solely on preservation; a balance between humans and technology and among structural and on-structural approaches; and a new balance of the sacred and utilitarian in water.

Field evidence AN - 17395395; 4617269 AB - Debris-laden ice accretes to the base of Matanuska Glacier, Alaska, U.S.A., from water that supercools while flowing in a distributed drainage system up the adverse slope of an overdeepening. Frazil ice grows in the water column and forms aggregates, while other ice grows on the glacier sole or on substrate materials. Sediment is trapped by this growing ice, forming stratified debris-laden basal ice. Growth rates of >0.1 m a super(-1) of debris-rich basal ice are possible. The large sediment fluxes that this mechanism allows may have implications for interpretation of the widespread deposits from ice that flowed through other overdeepenings, including Heinrich events and the till sheets south of the Laurentian Great Lakes.

We investigate the effects of terrain on crystal growth by using a two-dimensional finite-element model of heat flow coupled with a model of crystal growth from vapor. We used the model to examine the influence of snow properties, terrain geometry and snow depth on this phenomenon. The effect is stronger in the early winter than in the late winter, because the rock has then had time to cool. In all cases, we found that depth-hoar growth occurs preferentially over the rock. This suggests that snow-pit investigations made over soil can be misleading if rocky outcrops are present.

Policies that ensure effective contemporary water management will form the core of a "no regrets" strategy that will contemporaneously serve adaptation to climate change and uncertainty. Hence, an "adaptive management" approach rather than an "anticipatory strategy" is warranted for most water management actions. An effective water management system depends, to a large extent, on a well-functioning institutional framework and the treatment of water as an economic and social good, both of which are a prerequisite for adaptation to contemporary climate variability. It will also serve as the foundation for responding to uncertain climate change scenarios.

The US Army Engineer Waterways Experiment Station is engaged in research and development that will provide a seamless link to tools that combine diverse field data into accurate site characterizations, and perform computer simulations of remediation processes. However, the simulation models on which this capability is founded are still not adequate to simulate real, heterogeneous media that make up the natural groundwater environment. The inadequacy stems from the multi-scale structure of natural media that is masked by the continuum formulations upon which numerical models are based. The range of scales is simply too great to be spanned by any present, or foreseeable, HPC resource. To advance the science of multi-scale simulation, HPC may be viewed as an extension of the laboratory. By stretching present resources to perform scale-spanning simulations, stochastic models are created from data that could not be obtained previously from physical experiments. A detailed description of this process is presented for non-reactive, dispersive transport.

Questions targeted three areas of concern for fish and wildlife agencies: (1) what type of permit, if any, was required; (2) what information did the agency provide to the applicant; and (3) what mitigative techniques were required of the applicant by an agency or recommended to protect aquatic life from explosive pressures. Thirty-three state natural resource agencies require permits. Only two states, Oregon and Pennsylvania, have permit application forms specific to underwater explosive use and natural resource protection. Only five states provide an information package to the blaster. Seventeen mitigation measures were identified. They fall into three general categories: (1) review of the explosive design and provide mitigation recommendations based on that design; (2) evaluation of the potential impact and mitigative recommendations based on biological considerations; and, (3) evaluation of potential impact and require physical measures (e.g., bubble curtains, physical barriers, etc.) to minimize impacts. Each mitigation recommendation is reviewed based on existing literature and/or the physics of explosions. General mitigation recommendations are provided.

This study examined effects on these parameters as a function of altitude level and duration of exposure by administering standardized tests from 1 to 3 times to 23 males in an altitude chamber during 4.5-hour exposures to 3 levels of hypobaric hypoxia: 500 m, 4,200 m, and 4,700 m. Exposure to altitude significantly affected symptoms, moods, and performance in an elevation-dependent fashion. Adverse changes increased with higher altitudes (all measures were affected at 4,700 m, whereas only some were at 4,200 m) and usually with longer durations. Therefore, specific aspects of symptoms, moods, and performance are significantly degraded after only a few hours of exposure to hypobaric hypoxia, and the severity of the effects dramatically increases when testing is conducted at 4,700 m compared to 4,200 m.

By this parameter alone, PBL appeared more susceptible to SM-induced cytotoxicity than NHEK, as previously reported. However, there was a concentration-and time-dependent loss of NHEK yield that was not observed in PBL. Keratinocyte yield was approximately 46% and 8% of control cells at 12 and 24 hours, respectively, following exposure to 0.3 mM SM. The decrease in NHEK yield was associated with an increase in trypan blue-stained fragments observed on slides. Fragments were not observed on slides of SM-exposed PBL cultures. These results suggest that SM causes fragmentation of cultured NHEK and subsequently results in a lower cell yield. The fragmented dead NHEK are not included in the total cell count when percent viability is determined by propidium iodide exclusion. Therefore, cytotoxicity of SM in NHEK is greater than that reflected by dye exclusion alone. Actual viable cell count, which considers both propidium iodide exclusion and cell yield, indicates NHEK are more susceptible than PBL to SM-induced cytotoxicity, contrary to previously published reports. Cell yield must be taken into account when using in vitro models to study not only viability, but also any quantitative biochemical changes induced by SM.

A modified Nichols' method was used to measure daily food and water consumption. To estimate gastric transit, the total length amaranth (administered 40 minutes prior to sacrifice) dye traveled through small intestine were measured, and to determine gastric retention, the tied-off stomach pouch was removed and the contents weighed 24 hours after the last dose or when a rat became moribund or died. AM and AE dose solutions were prepared using sesame oil, whereas 50% dimethylacetamide (DMAC)/sesame oil was used for DQHS. The results showed that after dosing with 50 mg/kg for 7 days, 50% inhibition of food consumption (ID sub(50)) occurred at 1.9 days for DQHS, 3.9 days for AM, and 4.1 days for AE. Similar data were observed for water intake. After 100 mg/kg dosing, the ID sub(50)s for food and water consumption decreased to 2.8-2.9 days for AM and 3.1-3.7 days for AE. Food consumption and body weights were decreased following all three treatments, and rats exhibited neurologic symptoms at 25-100 mg/kg dose of DQHS and 50-100 mg/kg dose of AM and AE. In addition, the results constituted a 53% and 82% inhibition of gastric transit for AM and AE, respectively, at 25 mg/kg animals compared to control, and 100% inhibition was found in high doses (50 and 100 mg/kg) for all the three drugs. The gastric retention ratio (controls equal 1.0) was 26.0 for DQHS, 5.8 with AE,.

Insects are released, usually by researchers, with little or no direct input or effort by management personnel. However, the effectiveness of biological control could be enhanced if resource managers took an active role in its use. Four steps should be utilized in order to achieve a more active approach to the use of biological control. These include gaining an understanding of the insect agents, initiating yearly surveys to determine insect population levels and immediate and long-term impact, supplementing the insect populations if surveys reveal low numbers, and developing integrated procedures to minimize impact of the varied management techniques to one another. Utilizing a more active approach increases the awareness of biological control techniques and should result in increased effectiveness.

Continuing ecological research in this technology area strives to be relevant to aquatic plant management through a focus on the following areas; 1) improving the effectiveness of management techniques, 2) evaluating the effectiveness of management techniques, 3) evaluating the impacts of management techniques on nontarget species and environmental quality, and 4) preventing new infestations of nonnative aquatic plants. While both current and future planned research falls within these areas, specific research needs for the future have been identified in the areas of 1) developing standard aquatic plant quantification methods, 2) developing protocols for identifying the potential of new species to create nuisance problems, and 3) developing spatial databases and spatial models of plant distribution.

Since then, numerous insects and pathogens have been studied as potential agents for the management of target plant populations. Researchers have traveled to the countries of origin of six target plants (Eichhornia crassipes Mart. (Solms), Alternanthera philoxeroides (Mart.) Griseb., Myriophyllum spicatum L., Pistia stratiotes L., Hydrilla verticillata (L. F.) Royle, and Melaleuca quinquenervia (Cav.) S. T. Blake) to search for host specific agents. As a result, 13 insect biocontrol agents have been released as management tools lot five of these targets. On average these projects have developed one agent every 2.9 years. The CE also has conducted pathogen biological control research using endemic pathogens. More recently the CE has begun classical biocontrol studies using exotic pathogens as potential agents of aquatic plants. Research in the near future will be directed at the management of submersed aquatic vegetation. The past successes will be used to assist in directing the program, however, new emphasis will be placed on the development of more effective evaluation procedures to document impact of the biological control agents.

Data from lakes containing Eurasian watermilfoil were evaluated to compare the extent of Eurasian watermilfoil dominance to common limnological parameters. The best predictors of Eurasian watermilfoil dominance were water column total phosphorus and Carlson's Trophic State Index. This analysis corroborates observations that Eurasian watermilfoil appears most abundant in mesotrophic lakes and moderately eutrophic lakes.

Enzyme-linked immunosorbent assay (ELISA) was used to measure cytokine levels in adult and neonatal culture human epidermal keratinocytes (HEK) 3 h after exposure to 0.50 and 1.0 mM HD. A two-way analysis of variance was carried out for cell type and HD concentration. That analysis showed significant differences between cell types for IL-1 alpha and IL-1 beta (p = .001 and p = .015, respectively). In both of these cytokines, release in neonatal HEK decreased less than in adult HEK. A significant effect of HD concentration was shown only for IL-1 beta (p < .001), with cytokine release decreasing with increasing HD dose. In addition, a significant cell donor type by HD concentration interaction effect was found for IL-1 beta under the experimental conditions described in materials and methods. With increasing HD concentration, the relative decrease in cytokine release was much greater for adult than for neonatal HEK.

In a period of 27 h, GTN was completely degraded by free hydroxyl radicals when tested at 50 mg l super(-1) concentration. Degradation could not be accomplished by H sub(2)O sub(2) or the iron salt alone. A free hydroxyl radical scavenger, bulbocapnine, completely inhibited the degradation of GTN supporting the conclusion that the hydroxyl free radicals may be responsible for the degradation of GTN. Our previous investigation revealed that a fungal culture, Penicillium corylophilum Dierckz, has the capability to completely degrade GTN within 308 h. In the present investigation, we studied the possibility of the involvement of free hydroxyl radicals in the biodegradation of GTN. This study was carried out with the inclusion of bulbocapnine in the fungal growth medium indicating that the free hydroxyl radicals were not involved in the degradation of GTN by P. corylophilum.

Cell cultures from fetal rat cortex were exposed to TPEN for 2-24 h at 37 degree C. In the continuous presence of greater than or equal to 10 mu M TPEN for 24 h, light microscopy revealed morphological damage that included granular opacities in neural processes, cytoplasmic blebs of the soma, and, at higher concentrations, cellular detachment from the substrate. These changes were correlated with release of cellular LDH. Both morphological damage and LDH release increased over time. These cytotoxic effects apparently were linked to chelation of intracellular zinc by TPEN and could not be replicated with a 1:1 complex of Zn:TPEN or with the membrane impermeant chelator dipicolinic acid. Incubation of the cortical cells with the noncompetitive NMDA receptor antagonist MK-801 did not prevent TPEN-induced cytotoxicity or LDH release but could block glutamate-induced neuron damage. Patch-clamp recordings of spike activity in the cortical cultures also indicated no significant increase in spontaneous activity during the initial 2 h of TPEN application. Thus, the mechanism of TPEN cytotoxicity does not seem to be mediated by enhanced release of endogenous glutamate.

Although effective, these classically produced vaccines have several disadvantages. For live vaccines, the genetic lesion(s) responsible for the attenuation of the agent is mostly undefined, resulting in a greater risk of reversion and vaccine-induced disease. Inactivated vaccines are usually made by treating the agent with a chemical, such as formalin, to denature the toxin or to kill the agent. For killed vaccines, great care must be taken to ensure that the agent is inactivated completely or else it may cause disease in recipients. Even after formalin inactivation, there is the serious risk of reversion of the toxoid to its toxigenic form. Thus, every lot of toxoid vaccine must be extensively tested for its safety. Some inactivated vaccines also tend to have a higher frequency of reactogenicity, possibly due to the presence of other contaminants in the culture filtrates. Genetically engineered vaccines are able to circumvent many of these problems by having defined modifications in these agents, giving them specific properties. For attenuated vaccines, mutations can be selectively introduced into the genome of the agent to attenuate it so that it is nonpathogenic, but still immunogenic. For subunit vaccines, the sequence of the antigen can be modified or truncated so that it is nontoxic, but still retains most of the conformational epitopes required to elicit neutralizing antibodies. Vaccine antigens can also be expressed at high levels in a form and in a host that makes it easy to purify the antigen, resulting in a preparation that is lower in reactogenicity. For practical use, subunit vaccines are usually preferred over live vaccines. This is primarily due to safety concerns, as live vaccines present a greater risk of vaccine-induced complications. However, live vaccines are easier to produce and can elicit long-lasting immunity after only a single immunization. Molecular biology has opened up entirely new approaches to the development of vaccines that will affect how they are developed, manufactured, and administered. This review will attempt to summarize some of the systems that are currently available for making genetically engineered vaccines. It will by no means be a comprehensive review, but it should provide the reader with a feel for some of the concepts and issues that are associated with genetically engineered vaccines.

This new rule essentially provides that "any credible evidence" may be used for enforcement and compliance certification purposes under various provisions of the Clean Air Act and its implementing regulations, and clarifies that parties are not limited to the use of approved reference test methods. This paper begins with a discussion of the history of the credible evidence rulemaking and of reference methods in general. It then covers the final rule itself and EPA's concept of what constitutes "credible evidence." Next, it explores the major issues surrounding this rulemaking. Finally, it looks to the future - to the role of credible evidence under the recently promulgated Compliance Assurance Monitoring rule and to the current court challenges to the credible evidence rule.

This paper examines eight ebb shoal mining projects completed since 1981 in an attempt to examine this relatively new practice of removing material from an inlet ebb shoal. A brief description of each inlet's history, morphology, and processes is given in an Appendix for background information and available information on the ebb shoal mining events at each inlet is presented in this paper. The eight projects presented range in size from 170,000 m super(3) removed from the ebb shoal at Boca Raton Inlet (Florida) to 6,235,000 m super(3) removed from the ebb shoal at Great Egg Harbor Inlet (New Jersey). The recent completion of many of these projects and lack of systematic monitoring has resulted in limited monitoring data to assess shoal mining impacts on the inlet system. With this in mind, impacts of ebb shoal mining inferred from the data and the level of monitoring at each project site are discussed. From this study, it has been determined that most ebb shoals are mined on the outer "passive" portion of the shoal feature. Ebb shoal sand was found to be compatible with the native beach material, indicating that the ebb shoal acts as a "sand bridge" between the updrift and downdrift beaches. The rate of recovery of the mined area appears to be a function of the degree to which the system equilibrium is perturbed, sand availability (longshore transport rate), storm frequency, and the depth of the mined area. Estimates of borrow area recovery were often overpredicted, probably due to poor longshore transport estimates. Further analysis is needed to determine ebb shoal mining impacts to navigation, inlet adjacent shoreline, ebb shoal equilibrium, and reusability of borrow area infill material. This paper is an attempt to evaluate the state-of-the-art in the practice of removing material from inlet ebb shoals and monitoring of these projects. A suggested monitoring plan for future ebb shoal mining projects is also presented.

Dynamic studies AN - 16349849; 4308831 AB - This is the second part of a study conducted to determine whether polymeric sampling tubing can affect organic analyte concentrations during a sampling event. In this part of the study, we looked for sorption and desorption of trichloroethylene (TCE) and leaching of organic constituents in water pumped through five types of polymeric tubing. The materials tested were a rigid fluoropolymer, a flexible fluoropolymer, low-density polyethylene (LDPE), and two plasticized polypropylene tubings. The effects of tubing length and flow rate were examined. The least sorptive tubings, both initially and at equilibrium, were the fluoropolymers. However, in some instances the LDPE tubing had little effect on TCE concentrations. This was when a slow flow rate was used to sample relatively shallow wells (50 feet [15 m] or less) or when a faster flow rate (1 L/min) was used to sample wells that are less than 500 feet (152 m). Further testing is recommended using more sorptive analytes. Using high performance liquid chromatography (HPLC), we were unable to detect any constituents leaching from any of the tubings used in these studies, even when a slow flow rate was used. However, desorption of sorbed analytes is a concern for all the tubings tested, including the rigid fluoropolymer.

These two approaches of recovering VOCs from this matrix, and other forms of solid waste, are often used interchangeably without any recognition of how different parameters (environmental and procedural) influence their performance. Three vapor partitioning headspace and three solvent extraction methods of preparing soil samples for the determination of VOCs were compared, without being confounded by volatilization or biodegradation losses. Soil samples were spiked with five aromatic and four chlorinated compounds using two different laboratory procedures. Recovery efficiencies for the preparation methods tested depended on soil organic carbon content, the octanol-water partition coefficients of specific analytes, and the duration of solvent extraction. Overall, methanol extraction was the most efficient and robust method for recovering spiked VOCs. JF - Environmental Science & Technology AU - Hewitt, AD AD - Res. Phys.

O. Clark proposed a method to develop synthetic unit hydrographs for the modeling of watershed rainfall response. His technique utilizes two components: a translation hydrograph and a linear reservoir routing. Clark's three parameters (the time of concentration T sub(C), a storage attenuation coefficient R, and a time-area histogram) can be estimated for gauged basins. For ungauged basins, T sub(C) and R are difficult to estimate. T sub(C) can be approximated by analyzing physical basin characteristics whereas both T sub(C) and R have been successfully estimated using parameter regionalization. Technologies for observing and managing spatially distributed watershed and rainfall information are constantly evolving. The improved availability of areally oriented data brings the challenge of integration of these data into hydrologic models. The Hydrologic Engineering Center (HEC) has developed the program ModClark to take a first step in this integration. ModClark is based conceptually on Clark's 50-year-old method and uses next generation weather radar (NEXRAD) data. The ability of Clark's technique to accommodate the spatially distributed nature of rainfall and runoff illustrates the adaptability of Clark's original methodology. A demonstration of this adapted methodology is provided. JF - Journal of Hydrologic Engineering AU - Kull, D W AU - Feldman, AD AD - U.S. Army Corps Eng., Hydrologic Eng.

Electrokinetic soil treatment is an emerging technology that could prove to be very effective in the remediation of these sites. "Real-world" heavy metal contaminated (Pb(II), Cd(II), and Cr(III)) soils from three military sites with varying soil properties were subjected to electrokinetic treatment in the laboratory. Metal extractants (chelating agents and acids) were studied and found to be effective in enhancing the electrokinetic process. Results indicated that heavy metal removal efficiencies varied in the three soils tested. In one case, removal efficiencies of 90 percent and 60 percent were obtained for Cd and Cr, respectively, for the nitric acid amended experiments. For another case, over 60 percent of the total Pb in the system was deposited near the cathode for the non-amended and the citric-acid amended tests. Conversely, in the third case, the electrokinetic soil-washing treatment process failed to produce significant removal of any metal contaminant. The discrepancies that exist between the metal removal results of the three soils were attributed to the different physiochemical characteristics of each soil.

Initial tests, in which ethanol and ethyl ether were dosed into the feed as co-substrates confirmed that dinitrotoluene could be completely converted to diaminotoluene (DAT) which was subsequently decomposed aerobically in an activated sludge process. Further tests were carried out in a demonstration plant at the Radford, Va., ammunition factory in which a commercially-available 20 in diameter column with a bed volume of 710 litres was used under anaerobic conditions. The conversion rates obtained under these conditions were lower than those realised in the laboratory, principally on account of the smaller amounts of co-substrate available in the plant effluents.

The effects of both primary and secondary adsorptive sites were taken into account. Experimental data describing adsorption capacities of 4 activated carbon adsorbents were interpreted for relative vapour pressures from 0.0 to 0.95 and temperatures between 288 and 308K. Model results agreed closely with experimental results. Limiting pore volumes based on water vapour adsorption obtained from the model were comparable with those measured using volatile organic compounds.

AN - 79480765; 9407110 AB - Like other polycyclic aromatic hydrocarbons, certain metabolites of benz[a]anthracene have been implicated as potent carcinogens. These effects are thought to be caused by the covalent binding of these species to nucleophilic groups on the bases of DNA. To address the molecular mechanisms by which these molecules induce mutations, this study employed oligonucleotides containing four site-specific N6 adenine-benz[a]anthracene diol epoxide adducts. Using a prokaryotic in vivo replication system, we have shown that both non-bay region anti-trans-benz[a]anthracene adducts are essentially nonmutagenic. In contrast, the bay region anti-trans-benz[a]anthracene lesions do induce point mutations at the adduct site. The mutagenic frequency of these bay region lesions is dependent on the stereochemistry about the adduct-forming bond, as well as the strain of Escherichia coli in which they are replicated. The ability of the bacterial replication machinery to bypass the lesions does not correlate with the differences observed in their mutagenesis. While both non-bay region adducts are readily bypassed in vivo, the bay region adducts are both blocking to approximately the same degree. In vitro studies of the interactions of E. coli DNA polymerase III with these adducts have also been undertaken to further dissect the relationship between adduct structure and biological activity.

Characteristics of conifer canopies exert important control on the energy exchange at the forest floor, which in turn controls snow cover processes such as melting. This analysis investigated the role of the conifer tree characteristics, including height and canopy density. Canopy and snow models estimated radiation incoming to the snow surface, the net energy budget of the snow, and melting rates of snow cover under conifer forests with different canopy density and tree height. This analysis assumed that canopy effects dominated snow surface energy exchange under conifers in the boreal forest. We used data layers of forest characteristics from the Boreal Ecosystem-Atmosphere Study (BOREAS) modeling subareas in Saskatchewan and Manitoba to guide the choice of modeled tree height and canopy density. Modeled stand characteristics assumed random location of trees and used a uniform tree height within a stand and regular crown geometry scaled to tree height. Measurements during winter and thaw in 1994 of incoming solar and longwave radiation, humidity, and wind speed above the forest canopy provided input to the models, along with air temperature measured in the canopy. Results showed the importance of canopy density and tree height as the first-order controls on cumulative incoming solar radiation at the forest floor for the range of these variables in the BOREAS test area. The combined canopy and snow models showed a large range of snow ablation within conifers, which showed the trade-offs between canopy density and tree height. Solar fluxes dominated the net transfer of energy to the snow in the north, while sensible heat exchange, net solar, and net longwave radiation played important roles in the south.

This study is part of the Boreal Ecosystems Atmosphere Study (BOREAS) of central Saskatchewan and northern Manitoba. Forested environments provide unique problems for snow cover process modeling due to the complex interactions among snow, energy transfer, and trees. These problems are approached by coupling a modified snow process model with a model of radiative interactions with forest canopies. Additionally, a tree well model describes the influence of individual trees on snow distribution on the ground. The snow process and energy budget model calculates energy exchange at the snow surface, in-pack snow processes, melting and liquid water flow, heat conduction, and vapor diffusion. The surface radiation model provides input on the radiation receipt at the snow surface for model runs in the jack pine forest. Field data consisted of measured meteorological parameters above and within the canopy, spatial variability of snow properties, and variations of incoming solar irradiance beneath the forest canopy. Results show that the area beneath tree canopies accumulated 60% of the snow accumulated in forest openings. Peak solar irradiance on the snow cover was less than one half that measured above the canopy. Model runs are compared between the open and the forested sites and show the open area ablating four days before areas beneath the canopy and eight days before forest openings and compare favorably with measured data. Physically based modeling of snow ablation was successful at the forested site and nearby open area. JF - Journal of Geophysical Research. D.

AN - 79512817; 9425265 AB - The Russian-VX (R-VX) is the principle V-type nerve agent in the chemical warfare (CW) arsenal of the Former Soviet Union. We here report the enzymatic hydrolysis of the P-S bond of Russian-VX by organophosphorus hydrolase (OPH) from Pseudomonas diminuta. While the Michaelis constant, K(m) for R-VX (474 microM), was similar to that for VX (434 microM), the Vmax for R-VX (2.1 mumoles/mg/min) was about four-fold higher compared to that for VX (0.56 mumoles/mg/min). A 50% inhibition in the rate of the enzymatic hydrolysis of R-VX was observed in the presence of 0.5% ethanol, isoamyl-alcohol, or isopropanol. The presence of acetonitrile, diethylene glycol, or methanol had marginal effects. These results comprise the first demonstration of enzymatic detoxification of R-VX.

AN - 79442883; 9388535 AB - The remedial investigation/feasibility studies conducted at certain Army installations showed a need to clean up contaminated sites, where high levels of ammunition chemicals such as 2,4,6-trinitrotoluene (TNT), 1,3,5-trinitrobenzene (TNB), 1,3-dinitrobenzene (DNB), and their degradation products/metabolites were detected in surface soil and groundwater. TNB is a photodegradation product of TNT; it is not easily degraded, and persists in the environment. The toxicity data on TNB are scanty. Hence the U.S. Environmental Protection Agency in 1988 (U.S. EPA, 1997) developed a reference dose (RfD) for TNB (0.00005 mg/kg/d for chronic toxicity) based on the toxicity of DNB, which is structurally similar to TNB. Since then we have completed acute, subacute, subchronic, chronic, reproductive, and developmental toxicity studies and toxicokinetics studies. We have reviewed the mammalian toxicity data for TNB and have determined the no observed adverse effect levels (NOAEL) and low observed adverse effect levels (LOAEL) for subchronic, chronic, reproductive, and developmental toxicity. Based on the newly determined NOAEL and LOAEL values, we have now developed a new RfD for TNB (0.03 mg/kg/d), based on the chronic toxic effects on hematology and histopathological changes in testes and kidney.

AN - 79497000; 9415704 AB - Novel compounds, composed of two acridone moieties connected by a propyl or butyl spacer, were synthesized and tested as potential modulators of P-glycoprotein (P-gp)-mediated multidrug resistance. The propyl derivative 1,3-bis(9-oxoacridin-10-yl)-propane (PBA) was extremely potent and, at a concentration of 1 microM, increased steady state accumulation of vinblastine (VLB) approximately 9-fold in the multidrug-resistant cell line KB8-5. In contrast to the readily reversible effects of VRP and cyclosporin A on VLB uptake and similar to the effects of the cyclosporin analog PSC 833, this modulation by PBA was not fully reversed 6-8 hr after transfer of cells to PBA-free medium. Continuous exposure to 3 microM PBA was nontoxic and could completely reverse VLB resistance in KB8-5 cells. Consistent with its effects on VLB transport, the drug resistance-modulating effect of PSC 833 was significantly more persistent than that of VRP. However, the effect of PBA was, like that of VRP, rapidly reversed once the modulator was removed from the extracellular environment. PBA was able to compete with radiolabeled azidopine for binding to P-gp and to stimulate P-gp ATPase activity. However, both the steady state accumulation of PBA and the rate of efflux of PBA were similar in drug-sensitive KB3-1 and drug-resistant KB8-5 cells, suggesting that this compound is not efficiently transported by P-gp. These results indicate that PBA represents a new class of potent and poorly reversible synthetic modulators of P-gp-mediated VLB transport.

The results of these simulations have led to revised estimates of the energy dissipated in pressure ridging. This is important in large-scale ice ocean modeling, where the internal strength of the ice pack depends on the energy expended in pressure ridging. However, there has been no experimental data available to establish the accuracy of the simulations. This lack of data is due to the difficulty of modeling the pressure ridging process in the laboratory and of measuring ridge formation in the field. In this work the results of computer simulations of the closely related process of ice pile-up on an inclined ramp are directly compared with the results of a similar series of physical experiments conducted in an ice basin. In the experiments and simulations an inclined ramp is pushed against a long, stationary strip of intact, floating ice. The forces exerted on the ramp, the total energy expended, and the increase in the potential energy of the ice piled on the ramp are measured.

First- and second-degree frostbite accounted for 99.3% of all injuries. Although some soldiers had extensive lost duty time from their injuries, no one suffered tissue loss during the 5-year period. Fifty-one percent of injuries occurred during field training. Thirty-six percent occurred while engaging in garrison activities, including physical training, which accounted for 15% of all CWIs. Twelve percent of all injuries occurred during off-duty time. Seventy-one percent of CWIs occurred when the wind-chill factor was at or below -20 degree F (-29 degree C). Male African-American soldiers appear to be significantly more susceptible to frostbite than male Caucasian soldiers, especially with regard to frostbite of the distal extremities (relative risk = 3.94; 95% confidence interval = 2.77-5.59). Other identified risk factors include inadequate clothing, wet clothing, dehydration, inactivity, fatigue, and previous CWIs.

The Arctic is dominated by cold, wet, shallow soils often characterized by surficial organic horizons. Seven of 11 soil orders in Soil Taxonomy are present in the circumarctic and alpine zones of the ITEX Project. Soil organic matter is highly correlated to soil carbon (sink or source of atmospheric CO sub(2)), soil moisture (surficial energy balance), and soil nitrogen (plant limiting nutrient). Because of these vital roles, soil organic matter is a keystone that will influence the future response of arctic ecosystems to climate change.

The size of these sites range from the radioactive waste at Chernobyl in the Ukraine to a small construction debris site in your local neighborhood - and the risk is every bit as variable as the size. In summary, we must begin the paradigm shift from remediation to containment. While containment as the ultimate "fix" is not completely fulfilling, it is the only practical solution available. The procedure designs, contractors, materials, etc., are fully available and the situation is quite economical. Without emphasizing the obvious, geosynthetics play a key role in any waste containment strategy. They are well positioned to do so. Using a general contractor and an innovative Corps design featuring new bank protection methodologies, an 11,705 ft, 14-bend reach of a sinuous, incised, eroding stream was largely stabilized and rapidly maturing 1 year after project completion. Fifty-four Bendway Weirs and 9,383 willow posts were used to protect the 14 eroding bends. While problems with location of many of the Bendway Weirs and installation of the willow posts initially created some problems and repairs were needed in three locations, after three years and at least six out-of-bank flood events, over 11,000 ft of the project was stable. Stream corridor habitat was improved and project costs were approximately half of other projects in the area.

The molar percentage of rhamnose, a minor component in WSNCE-B, varied up to 13%, dependent on physiological conditions. No rhamnose was found in the WSNCE-B purified from the culture with initial medium pH greater than or equal to 6.8. The relative amount of mannose in WSNCE-B increased regularly with the amount of yeast extract added to the mineral salts medium. The relative amounts of glucose, mannose, and rhamnose in the WSNCE-B can be controlled by varying culture conditions.

In this study, the visible absorption spectra of three hemoglobin intermediates were experimentally determined and compared with computer-generated spectra. The data supported the assumption that the molar absorptivities of the intermediates are equivalent to the combined absorptivities of the component subunits. A multicomponent Fourier transform (FT)-aided full spectrum quantitation system (FSQ registered ) to simultaneously measure hemoglobin (Hb), hemimethemoglobin (hemiMetHb), and the cyanide complex dicyanohemimethemoglobin (dicyhemiMetHb) was also evaluated. It was found that FSQ had satisfactory accuracy and precision to quantitate hemiMetHb and dicyhemiMetHb at concentrations from 2 to 20% of the total Hb, a range commonly encountered in the treatment of cyanide poisoning using methemoglobin-forming agents. The simplicity and rapid throughput of the method make it suitable for clinical evaluation studies and form the basis for the design of a portable instrument for field analysis of these species.

Fifteen-minute critical swimming speeds ranged from 65 to 116 cm s super(-1). Sturgeon swam volitionally at low speeds (5 - 30 cm s super(-1)), but at higher speeds (40 - 120 cm s super(-1)) sturgeon alternated between active swimming and appressing themselves to the bottom of the tunnel. This second behavior is enhanced by sturgeon morphology - streamlined body shape, flat rostrum, and large pectoral fins. It allows shovelnose sturgeon to exploit river bottoms as a refugia from current and maintain position in high velocities.

Only the anti-PA polyclonal serum significantly protected the guinea pigs from death, with 67% of infected animals surviving. Although none of the MAbs was protective, one PA MAb caused a significant delay in time to death. Our findings demonstrate that antibodies produced against only PA can provide passive protection against anthrax infection in guinea pigs.

There is, however, little documentation on the efficacy of these devices. This paper examines the performance of four open-top chambers for altering temperature at six sites in the Arctic and Antarctica. Most of the heating effect was due to daytime warming above ambient; occasional night-time cooling below ambient, especially of air temperatures, depressed mean daily temperature. The mean daily temperatures at four arctic sites were generally increased by 1.2-1.8 degree C; but occasionally, temperature depressions also occurred. Under optimal conditions at the antarctic site (dry soils, no vegetation, high radiation) mean daily soil temperatures were increased by +2.2 degree C (-10 cm) to +5.2 degree C (0 cm). Protection from wind may play a more important role than temperature per se in providing a favourable environment for plant growth within open-top devices. Wind speed had a generally negative impact on mean daily temperature. Daily global radiation was both positively and negatively related to chamber temperature response. The effect of chambers on snow accumulation was variable with the Alexandra Fjord site showing an increased accumulation in chambers but no difference in the date of snowmelt, while at Latnjajaure in a deep snowfall site, snowmelt occurred 1-2 weeks earlier in chambers, potentially increasing the growing season. Selection of a passive temperature-enhancing system requires balancing the temperature enhancement desired against potential unwanted ecological effects such as chamber overheating and altered light, moisture, and wind. In general, the more closed the temperature-enhancing system, the higher is the temperature enhancement, but the larger are the unwanted ecological effects. Open-top chambers alter temperature significantly and minimize most unwanted ecological effects; as a consequence, these chambers are a useful tool for studying the response of high-latitude ecosystems to warming.

Changes in all these properties paralleled closely those found in cores from Byrd Station, Antarctica, and Dye 3, Greenland. Density increased progressively with depth to a maximum of 0.921 Mg/m (super 3) at about 1400 m, at which depth the ice became bubble free. Below about 2000 m, in situ densities began to decrease in response to increasing ice sheet temperatures. Since drilling, much of the ice core has undergone significant volume expansion (relaxation) due to microcracking and the exsolving of enclathratized gases, especially in the brittle ice zone between 650 and 1400 m. Grain size increased linearly to about 1000 m, thereafter remaining fairly constant until the Younger Dryas event at 1678 m where a twofold to threefold decrease in grain size occurred. These grain size changes were accompanied by a progressive clustering of crystal c axes toward the vertical, including a small increase in c axis concentration across the Younger Dryas/Holocene boundary. Increased dust levels in the Wisconsin ice have contributed to the maintenance of a fine-grained texture which, with its strong vertical c axis fabric, persisted to nearly 3000 m. However, beginning at about 2800 m, layers of coarse-grained ice intermixed with the much finer-grained matrix ice are observed. Below 3000 m the ice became very coarse grained. This change, attributed to annealing recrystallization at elevated temperatures in the ice sheet, was accompanied by a dispersed or ring-like redistribution of the c axes about the vertical. Ultrasonic measurements of vertical and horizontal P wave velocities made at 10-m intervals along the entire length of the GISP2 core fully confirmed the results of the crystallo-optical observations. A return to fine-grained ice coincided with the first appearance of brown, silty ice 13 m above bedrock. Bedrock material consisted of 48 cm of till, including boulders and cobbles, overlying gray biotite granite comprising the true bedrock. There is evidence that disturbed structure in the GISP2 cores begins little more than 70% of the way through the ice sheet. This disturbance increases with depth until it becomes large enough to cast suspicion on features lasting centuries or more in the bottom 10% of the ice sheet.

AN - 79555584; 9472323 AB - Recent published data show that transformation and sorption are key processes involved in the subsurface transport of TNT. The state-of-the-art understanding of TNT soil transformation and sorption phenomena is summarized below: There is unequivocal evidence of reductive transformation of TNT in soils. However, soil properties affecting TNT transformation are only partially understood. Edaphic factors such as redox are probably important since highest reductive transformation rates occur under anaerobic conditions. TNT transformation products include 2A-DNT, 4A-DNT, 2,4-DANT, and 2,6-DANT. Azoxytoluenes have also been reported. Triaminotoluene may be an important TNT transformation product, but this product has not been routinely measured. TNT soil sorption is rapid and can be modeled as equilibrium controlled. Poor mass balances are difficult to interpret owing to lack of information on transformation products. Various irreversible disappearance mechanisms other than transformation to elutable transformation products are possible.

AN - 79552415; 9472321 AB - A great deal of interest has been generated recently in the determination of explosives and explosives by-products in exotic matrices including composts, bioslurries, and plants. The methods traditionally utilized for the analysis of organic and inorganic contaminants in these types of environmental samples are not adequate owing to the unique properties of the material being studied. The methods used to detect the nitramines and their degradation products in a variety of environmental samples requires matrix-specific sample preparation, separation by reversed phase high performance liquid chromatography, and ultra-violet detection. Knowledge of the concentration of the contaminants and the molecular state of their degradation products is helpful in assessing the environmental risks associated with the contaminants as well as the design of remediation technologies. Data that are obtained using analytical methods not designed for the specific matrix encountered may lead to incorrect quantitation. Examples of remediation technologies that necessitate the analysis of other than standard matrices for explosives include composting, aerobic and anaerobic microbial degradation, and plant-assisted degradation. The toxicity and mobility of explosives in the food chain are also of interest, and analytical techniques for studying explosives in plant and animal tissues that provide valid information regarding trace levels in these matrices are also required. The report will address three important points in connection with the problem. The extraction of the contaminants from the matrix requires a different set of extraction techniques than those utilized for standard water and soil extractions. These exotic matrices contain much higher organic content than soil or water and, as a result, are prone to interference from biological molecules.

AN - 79552156; 9472311 AB - The Department of Defense (DoD) has over 21,000 contaminated sites requiring some form of remediation. Contaminants on these sites include explosive compounds (i.e., TNT, RDX, HMX), chlorinated solvents (i.e., PCE, TCE, TCA), polycyclic aromatic hydrocarbons (i.e., benzo-a-pyrene), and polychlorinated biphenyls (i.e., aroclors). Current technology has centered around incineration, air stripping, and the use of activated carbon. Frequently, this technology is not cost effective nor publicly acceptable. Biotreatment offers a possible alternative. Biotreatment can cost effectively eliminate contaminants and avoid the use of harsh chemicals and physical treatments. However, special care must be employed to ensure that the proper remediation system is designed and engineered to optimize clean-up and minimize costs. Unfortunately, not all bioremediation efforts have been successful. In an attempt to develop bioremediation technology from the flask (bench scale) to the field (full-scale design), many scientists and engineers have failed to understand the phenomena that influence bioremediation. Issues such as additional mass transport mechanisms/limitations, the presence of multiple phases, spatial heterogeneities, and unfavorable factors for bacterial growth represent only a few of the phenomena that can limit or complicate biodegradation. Successful bioremediation requires a complete examination of the phenomena that can be observed as the scientist and engineer progress together from the bench to the field. An excellent way to examine these phenomena is by using the conceptual scales of observation: microscale, mesoscale, and macroscale. The microscale represents the level at which chemical/microbial species and reactions can be characterized independently of any transport phenomena. These activities are those occurring at the microbial cell level and generally are the focus of bench level work. The mesoscale is the level at which transport phenomena and system geometry are first apparent, with the exclusion of advective or mixing processes. This scale represents those activities that occur at the pore channel, soil particle or microbial aggregate level. The macroscale is the scale at which you have the ability to discern advective or mixing phenomena. These activities are generally associated on a site level and are the focus of the design engineer. The critical path as bioremediation technology is developed from flask to field is to observe and understand the phenomena that exert influence at each scale of observation so that its effects can be incorporated into the final remediation design.

AN - 79533772; 9447235 AB - To test the hypothesis that mitochondrial DNA (mtDNA) is more prone to reactive oxygen species (ROS) damage than nuclear DNA, a continuous flux of hydrogen peroxide (H2O2) was produced with the glucose/glucose oxidase system. Using a horse radish peroxidase (HRPO)-based colorimetric assay to detect H2O2, glucose oxidase (GO; 12 mU/ml) produced 95 microM of H2O2 in 1 h, whereas only 46 microM of hydrogen peroxide accumulated in the presence of SV40-transformed human fibroblasts ( approximately 1 x 10(6). DNA damage was assessed in the mitochondira and three nuclear regions using a quantitative PCR assay. GO (12 mU/ml) resulted in more damage to the mitochondrial DNA (2.250 +/- 0.045 lesions/10 kb) than in any one of three nuclear targets, which included the non-expressed beta-globin locus (0.436 +/- 0.029 lesions/10 kb); and the active DNA polymerase b gene (0.442 +/- 0.037 lesions/10 kb); and the active hprt gene (0.310 +/- 0.025). Damage to the mtDNA occurred within 15 min of GO treatment, whereas nuclear damage did not appear until after 30 min, and reached a maximum after 60 min. Repair of mitochondrial damage after a 15 min GO (6 mU/ml) treatment was examined. Mitochondria repaired 50% of the damage after 1 h, and by 6 h all the damage was repaired. Higher doses of GO-generated H202, or more extended treatment periods, lead to mitochondrial DNA damage which was not repaired. Mitochondrial function was monitored using the MTT (3,(4,5-dimethylthiazol-2-yl)2,5-diphenyltetrazolium bromide) assay. A 15 min treatment with 6 mU/ml of GO decreased mitochondrial activity to 80% of the control; the activity recovered completely within 1 h after damage. These data show that GO-generated H202 causes acute damage to mtDNA and function, and demonstrate that this organelle is an important site for the cellular toxicity of ROS.

Changes in bubble and grain structure caused by near-surface, primarily summertime formation of hoar complexes provide the main visible annual marker in the Holocene, and changes in "cloudiness" of the ice correlated with dustiness mark Wisconsinan annual cycles; both markers are evident and have been intercalibrated in early Holocene ice. Layer counts are reproducible between different workers and for one worker at different times, with 1% error over century-length times in the Holocene. Reproducibility is typically 5% in Wisconsinan ice-age ice and decreases with increasing age and depth. Cumulative ages from visible stratigraphy are not significantly different from independent ages of prominent events for ice older than the historical record and younger than approximately 50,000 years. Visible observations are not greatly degraded by "brittle ice" or many other core-quality problems, allowing construction of long, consistently sampled time series. High accuracy requires careful study of the core by dedicated observers. Copyright 1997 by the American Geophysical Union.

The ice at 2800 m is dated at 110,000 years B.P. with an estimated error ranging from 1 to 10% in the top 2500 m of the core and averaging 20% between 2500 and 2800 m. Parameters used to date the core include visual stratigraphy, oxygen isotopic ratios of the ice, electrical conductivity measurements, laser-light scattering from dust, volcanic signals, and major ion chemistry. GISP2 ages for major climatic events agree with independent ages based on varve chronologies, calibrated radiocarbon dates, and other techniques within the combined uncertainties. Good agreement also is obtained with Greenland Ice Core Project ice core dates and with the SPECMAP marine timescale after correlation through the delta (super 18) O of O (sub 2) . Although the core is deformed below 2800 m and the continuity of the record is unclear, we attempted to date this section of the core on the basis of the laser-light scattering of dust in the ice.

Vertical thin sections of the Greenland Ice Sheet Project 2 ice core show that in the lower 30%, the expected c axis-vertical fabric is interrupted by planes of grains ("stripes") with c axes oriented approximately in the dip directions of the planes. Stripe-parallel shear produces small-scale folds. The stripes can be explained qualitatively by a simple nucleation-and-growth model based on the strong anisotropy of ice-crystal deformation. Nucleation probably is sensitive to spatially variable rates of polygonization, producing spatially variable stripe densities. Stripes are modeled to affect the ice viscosity, so variations in stripe density may contribute to viscosity contrasts that might produce larger deformational features and loss of stratigraphic order.

However, the distinction is often arbitrary. Near-surface geophysics, for most applications, has three distinguishing characteristics not shared with regional geophysics or oil and gas exploration: very high resolution surveys; public health and safety concerns; and near real-time validation or ground truthing of the interpretations. An overview of a variety of novel near-surface geophysics applications is presented.

This law is the driving force behind the Department of Defense (DOD) ecological risk assessment (ERA) program. Ecological risk assessments are currently underway at many DOD sites with budgets ranging from five thousand to ten million dollars. However, with the advent of downsizing government and shrinking funds, efforts are being made within DOD to better refine these assessments. Two DOD work groups function to develop guidance for and assist project managers with the ERA process. These groups are the Army Biological Technical Assistance Group chaired by the Army Environmental Center and the Tri-Service Ecological Risk Assessment Work Group (ERWG) chartered by the Tri-Service Environmental Support Centers Coordinating Committee. Membership in the Tri-Service ERWG includes all facets of DOD. In the research arena, the Fate & Effects Research and Development Program is one of four primary thrust areas under the Army's Environmental Quality Technology Program "Clean Up" pillar. This program is currently being executed by three laboratories, the Waterways Experiment Station, Vicksburg, MS, the Army Center for Health Promotion and Preventive Medicine, Aberdeen Proving Ground, MD, and the Army Center for Environmental Health Research (Provisional), Ft. Detrick, MD. The goal of this program is to provide tools to improve environmental risk assessments, both human and ecological. The research is geared toward addressing user requirements and is defined by the Fate and Effects Research Program.

It's an ideal example of American technology, creativity, and entrepreneurship. The bridge, located adjacent to Lock and Dam No. 15, consists of two riveted Pratt through trusses, five riveted Baltimore trusses, and a camelback center-pivoted swing truss. The paper discusses the unique problems encountered during construction of the bridge, as well as its upgradings and maintenance. Many projects have been undertaken in the 100 years since the completion of the bridge. In each case, the structure was designed as near state of the art, but with rapidly increasing loading of the equipment operated over the bridge, modifications have been necessary to strengthen the spans and floor systems, as well as nearly all the other components of the structure. Several changes also have been required due to the Mississippi River Navigation projects and the increased highway traffic. Repairs to combat the aging process were done annually as a routine matter. The bridge was the first major accomplishment of Chicago engineer Ralph Modjeski, who subsequently established a reputation as one of the country's leading bridge designers.

While phase I cellular Q fever vaccines are efficacious in humans, vaccination of immune individuals may result in sterile abscesses and granulomas. The chloroform:methanol residue vaccine (CMR) was developed as a safer alternative. The efficacy of a licensed phase I cellular vaccine (Q-Vax) was compared with that of CMR vaccine in A/J mice and Hartley guinea pigs challenged with virulent phase I C. burnetii by aerosol. Both vaccines were efficacious. The CMR vaccine dose required to protect 50% of mice (PD sub(50)) against lethal aerosol challenge (11 LD sub(50)) was one-third of the Q-Vax dose. However, the PD sub(50) for CMR was four times the Q-Vax dose in guinea pigs challenged by aerosol (60 LD sub(50)). It was concluded that CMR is an efficacious alternative to cellular Q fever vaccines for the prevention of Q fever.

AN - 79324804; 9325255 AB - DNA lesions in the template strand pose a block to the replication machinery. Replication across such lesions may occur by a mutagenic bypass process in which a wrong base is inserted opposite the lesion or may involve processes that are relatively error-free. Genetic studies in the yeast Saccharomyces cerevisiae have indicated the requirement of REV3-encoded DNA polymerase in mutagenic bypass. The DNA polymerase responsible for error-free bypass, however, has not been identified, but genetic studies implicating proliferating cell nuclear antigen in this process have suggested that either DNA polymerase delta or DNA polymerase epsilon may be involved. Here, we use temperature-sensitive (ts) conditional lethal mutations of the S. cerevisiae POL2 and POL3 genes, which encode DNA polymerase epsilon and delta, respectively, and show that post-replicational bypass of UV-damaged DNA is severely inhibited in the pol3-3 mutant at the restrictive temperature. By contrast, the pol-2-18 mutation has no adverse effect on this process at the restrictive temperature. From these observations, we infer a requirement of DNA polymerase delta in post-replicative bypass of UV-damaged DNA.

AN - 79464710; 9414374 AB - This study examined the influence of a generalized physical fitness training program on manual material handling (MMH) capability. Thirteen healthy women trained for 14 weeks, performing progressive resistance training three days per week and running with interval training two days per week. Subjects attended 85 +/- 6% of the sessions. Compared to values obtained before training, subjects increased the maximum mass they could lift from floor to knuckle height by 19% (68-81 kg, p < 0.001) and from floor to chest height by 16% (49-57 kg, p < 0.001). They improved by 17% their ability to lift 15 kg as many times as possible in 10 min(167-195 lifts, p < 0.001), while perception of effort (measured with the Borg Rating of Perceived Exertion) did not change. Total body mass did not change, but body fat mass was reduced by 9% (18.8-17.2 kg, p = 0.036) and fat-free mass increased by 6% (48.2-51.0 kg, p < 0.001). A short-term physical fitness program, conducted about 1 h per day, five days per week, can substantially improve women's MMH capability and provide favorable changes in body composition (increased fat-free mass and decreased body fat.

AN - 79441163; 9388028 AB - Clostridium botulinum may produce any of seven known serotypes of neurotoxin (BoNT/A-/G), which are the most toxic bacterial proteins known. Efforts to develop a second-generation vaccine to these toxins would benefit from the isolation of hybridomas producing neutralizing monoclonal antibodies (MAbs). We hypothesized that previous efforts to isolate neutralizing MAbs against various BoNTs failed due to use of toxoided, chemically altered antigens. We employed a novel vaccination regimen employing native, active, single-chain BoNT/E (scBoNT/E). A number of the BoNT/E immunized mice were further vaccinated with lethal doses of fully active BoNT/F. MAb 7F8 consistently neutralized BoNT/F in three different assays: in vivo neutralization, passive neutralization, and neutralization of regional paralysis. There was no detectable recognition and essentially no neutralization of scBoNT/E. The epitope recognized by this MAb was denatured when treated with formalin, urea, guanidine chloride, or sodium dodecyl sulfate.

AN - 79390245; 9357497 AB - Pulsed carbon dioxide (CO2) laser debridement is now being used as therapy for photodamaged skin. It has been proposed that the long duration of erythema and a tissue scaffold, which results from tightening of the collagen helix induced by the laser heat, may lead to tightening of sagging skin and skin creases of lesser magnitude. Weanling pigs exposed to mild and moderate erythema producing doses of sulfur mustard (bis-2-chloroethyl sulfide; HD) were treated with the CO2 laser (Tru-Pulse) at 6, 24, and 48 hours after exposure. In addition to histologic examination of laser-debrided and nondebrided biopsy specimens obtained at 14 days after exposure, immunohistochemical staining with antibodies to smooth muscle actin, Factor XIIIa, vimentin, and CD3 was performed. CO2 laser debridement of the HD-exposed skin resulted in clearing of the cytologic atypia induced by this chemical carcinogen and reduced the inflammatory infiltrate. In addition laser debridement resulted in increased numbers of stromal cells within the papillary dermis, which showed immunohistochemical staining for smooth muscle actin, Factor XIIIa, and vimentin. CO2 laser debridement is effective in clearing the epidermis of cytologically damage cells in HD as well as solar-damaged skin. In addition CO2 laser debridement may result in tightening of sagging skin and produce a decrease in skin creases initially, by inducing increased stromal cells within the papillary dermis, with prominent contractile actin filaments. The collagen produced by these stromal cells may subsequently maintain these improvements in the photoaged skin.

AN - 79324642; 9327120 AB - Fatigue is an insidious threat to aviation safety because of the impairments in alertness and performance it creates. The fatigue associated with sleep loss, shift work, and long duty cycles can cause aviators to become sloppy, inattentive, careless, and inefficient. The only cure for fatigue is adequate sleep; however, gaining sufficient amounts of sleep is often difficult because of work requirements, family demands, or poor sleep habits. Although it may not be possible to avoid some of these problems, pilots can improve their sleep habits and thus gain more restful and restorative sleep by using self-administered relaxation therapy, establishing consistent and soothing bedtime routines, and avoiding certain activities and substances immediately prior to sleep. When opportunities for adequate sleep are not available because of work-related factors, prophylactic naps can sustain performance until sleep is possible.

AN - 79320127; 9327117 AB - A comprehensive study of the effect of Head-Supported Devices (HSDs) on neck loading during helicopter accidents is presented. The new Articulated Total Body (ATB) model which treats the neck as a deformable segment was used for crash simulation. Different categories of human and manikin subjects were considered under several crash scenarios. Simulations were theoretically designed to include a wide range of HSDs by changing their weights and center of gravity (CG) locations relative to the head, and studying the effects of these changes. Since HSDs were only theoretically included in the model, detachment of specific detachable devices used in most military applications was not modeled in the study. Hence, two typical detachable devices were modeled and selected simulations were repeated and compared not only to provide a measure of accuracy for the original results but also to see the effect of separation of these devices from the helmet.

The model is designed specifically for simulation of flow in channels having sloping sidewalls in which the depth is an unknown variable in the governing equations and therefore the plan view of the flow domain is not known a priori. Solutions are obtained by time stepping from specified initial conditions using an implicit Petrov-Galerkin moving finite-element representation of the governing equations. The moving finite-element model produces a simultaneous solution for the boundary displacement and flow variables. This implementation provides stable solutions for supercritical flow even at relatively large Courant numbers. The model is tested by comparison of simulation results with laboratory data. These data sets serve as a basis for evaluation of the numerical model and should also prove useful to researchers in testing other numerical flow models applied to supercritical flow in channels having sloping sidewalls.

Narrow-channel runs AN - 16347974; 4302578 AB - We present the results of three laboratory experiments in which longitudinally sorted deposits were formed by feeding poorly sorted sediment at the upstream end of a narrow, 45-m-long channel. The input sediment had a median size of 6 mm and included significant amounts of material up to 64 mm and down to 0.2 mm. Water discharge was constant at 49 L/s and sediment discharge varied from 0.048 to 0.19 kg/s. Downstream fining was produced in all three runs; the variation in sediment-feed rate had relatively little effect on the fining profiles. In all three runs, the formation of a longitudinally sorted deposit was mediated by the formation of a coarse surface layer. The surface layer remained at the top of the deposit during aggradation by continually reforming itself at the deposit surface. The coarse surface layer fined by approximately a factor of 2 in D sub(90) and D sub(50) consistently in all three experiments. The deposit (subsurface) fined less, with D sub(90) fining more strongly than D sub(50). The short channel length and the relatively high rate of deposition rule out clast abrasion as the source of fining. The experiments suggest that selective deposition of the coarsest clasts due to unequal mobility is capable of producing fining rates comparable with the highest rates observed in nature.

For both onshore and offshore winds, the midrange of the spectrum loses up to 40% of the energy content, while the low- and high-frequency ranges have an energy gain. In the onshore case, gain in the high-frequency range dominates, and in the offshore wind case (predominant wave energy propagation is still shoreward), gain in the low-frequency region dominates.

The observations include height, period, and direction as well as frequency and directional spectra. The wave measurements are separated by 90 km with simple bathymetry. During the active wind-sea growth (winds of 25 m/s), spatial and temporal changes in the wave field indicate that a quasi-steady-state assumption is no longer valid. Later, the wave field becomes a mixture of two wave systems: swell out of the northeast and a wind-sea system from the northwest. It is concluded that even for a relatively simple storm, evaluation of the physical mechanisms and prediction require a time-dependent numerical model.

Coastal wetland areas on each Great Lake expand or contract in response to the long-term water level fluctuations. The water level of the St. Marys River, a connecting channel between Lakes Superior and Huron, is largely controlled by the level of Lake Huron. The St. Marys River wetlands expand and contract in a fashion similar to wetlands on the lakes. Data on St. Marys River wetland areas were derived from historical aerial photographs and placed in a Geographic Information System (GIS) to analyze the effects of water level fluctuations. The GIS was used to measure wetland area changes between the years for which photographic data were available. Use of GIS allowed quantification of wetland area changes, estimation of response rates and description of inter-class transfer dynamics, for five coastal wetland classes influenced by long-term water level fluctuations.

ER - TY - JOUR T1 - Establishment of native aquatic plants for fish habitat: Test plantings in two north Texas reservoirs AN - 16326413; 4261240 AB - Test plantings of native aquatic plant species were made in two Texas reservoirs. Founder populations of three native submersed or floating-leaved species were established within small (2- x 2-m) exclosures utilizing actively growing transplants. Herbivory and excessive sedimentation proved to be deterrents to plant survival and expansion. Nine small founder populations of Vallisneria americana were established within North Lake, a small reservoir with limited water level fluctuations and a developing community of native pioneer aquatic plants. Plants within all nine exclosures successfully established and began vegetative growth. In intact exclosures, the plants rapidly covered the sediment surface within the exclosures. Expansion beyond the exclosures was variable and occurred primarily during the cooler portions of the year when herbivory was assumed to be low. During the spring of the second growing season, herbivores cropped most of the previous expansion leaving only a narrow fringe of plants surrounding the exclosures. At Lewisville Lake, a large, turbid reservoir with significant seasonal water level fluctuations and no existing aquatic macrophytes, two native pioneer species (Potamogeton nodosus and Heteranthera dubia) were planted within exclosures. Good survival and growth occurred within undamaged exclosures, although no expansion ever occurred outside the fenced areas. Plantings of H. dubia in undamaged exclosures also showed excellent survival except for those planted in areas subject to very high turbidity and sedimentation rates. Again, herbivory prevented any expansion outside the protective exclosures.

The study found that advection distances were considerably greater than would be expected from wind forces acting on spherical droplets. Flattening of the windward face of water droplets from splash and spray in the presence of strong wind was found to increase the drag of droplets in this study and possibly add a lifting force, thereby increasing the distances droplets were carried. Results of this study indicate that splash and spray may be carried over a coastal structure considerably farther than may be expected, which in turn may contribute to higher overtopping rates.

This situation is exacerbated because the processes that control the mobility and transformation of TNT are not well understood. The objective of this study was to determine the effects of redox potential (Eh) and pH on the fate and transformation of TNT in soil. An initial investigation of soil components responsible for the observed TNT transformation was also conducted. Laboratory investigations consisted of testing at four separate redox potentials and four pH levels. An 18:1 (water:soil) suspension spiked with 100 mu g/g TNT was used. Results indicated that TNT was unstable under all redox and pH conditions, and was least stable under highly reducing conditions at all four pH values. Greater amounts of TNT were incorporated into soil organic matter under anaerobic than under aerobic conditions. Results of the soil component study indicated that the presence of Fe super(+2) sorbed to clay surfaces may account for the rapid disappearance of TNT at reduced redox potentials. TNT in ground water moving into areas of intense reduction would not persist for long, but would undergo transformation and binding by soil organic matter.

Pla of the KIM-10 strain of Y. pestis appears to be required for the virulence from a subcutaneous (sc) but not an intraperitoneal (ip) or intravenous (iv) route of infection in mice. However, other strains of Y. pestis are highly virulent by the sc route yet lack pPst and pla. In this study, the pPst super(-) Pestoides F strain was lethal to mice inoculated sc, with an LD sub(50) (3 cfu), equal to that of C092, a virulent pPst super(+) strain. To analyse further the role of Pla in invasive infection, isogenic derivatives of C092, including one harboring pla with a frameshift mutation and another cured of pPst, were made. Although the ip LD sub(50) of pPst super(-) C092 and of the pla mutant were nearly identical to that of the wild type, the subcutaneous LD sub(50) of the cured and mutant strains were 4 to 6 logs greater than that of wild type. Thus, pPst appears to be required for development of a lethal infection by some strains after sc inoculation but not after direct ip inoculation. Pla-associated virulence did not appear to be mediated by interference with the phagocyte chemoattractant C5a, as shown by the lack of correlation of C5a production with susceptibility to Y. pestis in C5a super(+) and C5a super(-) congenic mice. In a footpad model of the early host response to subcutaneous infection, pPst super(-) C092 proliferated at the subcutaneous injection site to a similar extent as did the wild type parent strain, and elicited a similarly large, local inflammatory response. However, the wild type was present at higher concentrations at more distant sites such as the popliteal lymph node and spleen.

Four silvicultural treatments were randomly assigned to the twelve plots in the fall of 1988. Plots were thinned to a density of 731 trees per hectare or left unthinned, at a density of 2990 trees per hectare. The plots were left unfertilized or fertilized with 744 kg /ha of diammonium triple superphosphate was applied. During the fifth growing season (1993) following thinning and fertilization, needle level physiology was not different with respect to the thinning treatment for fertilized or unfertilized plots. In contrast, upper crown levels within the fertilized and unfertilized plots had significantly higher light levels and photosynthetic rates than lower crown foliage. Light levels were greater in the thinned, fertilized plots than in the unthinned, fertilized plots. In contrast, no effect of thinning on canopy light levels was found in the unfertilized plots. Within crown variation in photosynthesis was strongly dependent on canopy light levels. A strong interaction of canopy level with thinning was apparent for net photosynthesis. Loblolly pine, being a shade intolerant species, showed only small physiological differences between needles from different parts of the crown.

AN - 79267478; 9287349 AB - The RAD6 and RAD18 genes of Saccharomyces cerevisiae are required for postreplicative bypass of ultraviolet (UV)-damaged DNA and for UV mutagenesis. The RAD6 encoded protein is a ubiquitin conjugating enzyme, and RAD18 encodes a protein containing a RING finger motif and a nucleotide binding motif. Rad18 can be co-immunoprecipitated with Rad6, indicating that the two proteins exist in a complex in vivo. Here, we co-overproduce the two proteins using a yeast multicopy plasmid, purify the Rad6-Rad18 complex to near homogeneity, and show that the complex is heterodimeric. The Rad6-Rad18 heterodimer has ubiquitin conjugating activity, binds single-stranded DNA, and possesses single-stranded DNA-dependent ATPase activity. The Rad6-Rad18 complex provides the first example wherein a ubiquitin conjugating activity is physically associated with DNA binding and ATPase activities provided by an associated protein factor. The co-existence of these activities should provide the complex with the ability to recognize single-stranded DNA resulting from stalling of the replication machinery at DNA damage sites and to recognize the components of the DNA replication machinery for ubiquitination by Rad6.

AN - 79475059; 9403967 AB - Certain aminoquinoline antimalarial compounds, such as chloroquine, antagonize the paralytic actions of botulinum neurotoxins (BoNT). These studies have been extended to determine the critical structural groups necessary for synthetic aminoquinolines to have antagonist activity against BoNT. Isolated mouse hemidiaphragms were maintained at 36 degrees C and indirectly stimulated; the resulting isometric twitch tensions were recorded as a measure of synaptic function. The muscles were exposed to the test compounds before being treated with a challenge concentration of BoNT (typically 0.2 nM of serotype A). The time to onset of 50% muscle paralysis due to BoNT was used to assess quantitatively the efficacy of the test compounds, which were then ranked on the basis of the concentrations necessary to delay paralysis by a specified time increment. Of the compounds tested, those having a 7-chloro-4-aminoquinoline configuration, similar to chloroquine (or the structurally similar 6-chloro-9-amino acridine group in quinacrine), were most effective. Truncation of the alkyl-amino-alkyl group from chloroquine and conversion of the 4-amino nitrogen to a primary amine did not significantly alter its effectiveness as a BoNT antagonist. However, the 6-chloro- or 8-chloro- isomers of chloroquine were essentially ineffective. These results suggest that aminoquinolines antagonize the paralytic actions of BoNT through interaction with a selective, stereospecific site that is not well correlated with antimalarial activity.

AN - 79379077; 9353792 AB - This paper proposes a three phase "model" of the neuropharmacological processes responsible for the seizures and neuropathology produced by nerve agent intoxication. Initiation and early expression of the seizures are cholinergic phenomenon; anticholinergics readily terminate seizures at this stage and no neuropathology is evident. However, if not checked, a transition phase occurs during which the neuronal excitation of the seizure per se perturbs other neurotransmitter systems: excitatory amino acid (EAA) levels increase reinforcing the seizure activity; control with anticholinergics becomes less effective; mild neuropathology is occasionally observed. With prolonged epileptiform activity the seizure enters a predominantly non-cholinergic phase: it becomes refractory to some anticholinergics; benzodiazepines and N-methyl-D-aspartate (NMDA) antagonists remain effective as anticonvulsants, but require anticholinergic co-administration; mild neuropathology is evident in multiple brain regions. Excessive influx of calcium due to repeated seizure-induced depolarization and prolonged stimulation of NMDA receptors is proposed as the ultimate cause of neuropathology. The model and data indicate that rapid and aggressive management of seizures is essential to prevent neuropathology from nerve agent exposure.

The cloned segment contains two first exons that were earlier identified and named exons 1a and 1b. These were found to be separated by approximately 800 bp. The minimal promoter region was identified upstream to the distal exon 1a, by transient transfection, and no promoter activity was found in the region in between exons 1a and 1b, suggesting that transcription starts at a single site which is then processed to generate mRNAs of the isoforms. The promoter sequence is G and C rich and contains neither TATA box, nor apparent CAAT sequences, although a partially matched CAAT sequence was identified just downstream to the minimal promoter.

Serum levels of the cytokines interleukin 2 (IL-2) and interleukin 6 (IL-6) increased significantly (p < 0.01) in six juvenile rhesus monkeys 4 hours after receiving a nonlethal, inhaled dose of SEB. The mean (+/-SD) peak serum levels of IL-2 and IL-6 were 63 +/- 39 units/ml and 514 +/- 234 pg/ml, respectively, post-SEB treatment. Tumor necrosis factor, known to be associated with SEB-mediated lethal toxic shock, was undetectable in all samples. gamma-Interferon concentrations were also elevated, but not significantly [p < 0.089]. Hence, elevated levels of IL-2 and IL-6 might be used as a serological marker for a nonlethal, incapacitating exposure to SEB.

Four hundred soldiers belonging to this battalion were surveyed to determine the prevalence of the WWIF syndrome. One hundred forty-nine soldiers surveyed developed the WWIF syndrome. The affected soldiers had a wide range of disability, ranging from mild discomfort to the inability to ambulate. All soldiers had full recovery within 2 weeks of the injuries. Although the syndrome is self-limited, the loss of these soldiers from combat critically impaired the battalion in its mission.

LAAP is a government owned facility located 22 miles east of Shreveport, LA. The 14, 974 acre plant manufactured high explosives (TNT and RDX) and load and pack ammunition items between 1942 and 1995. As part of the manufacturing activities, 16 unlined ponds were dug in fine grained silty-sands to contain the wastewater contaminated with TNT and RDX. These ponds covered an area of approximately 25 acres and received explosive-laden water sporadically between 1942 and 1981. LAAP was selected for the natural attenuation project because the source of contamination has been removed, ten years of annual ground water quality data exists, and 71 monitoring wells are installed on the site. Of the 71 existing wells, 30 were selected for a two year sampling program. These 30 wells were sampled and analyzed for explosives monthly from February through August 1996 and will be monitored quarterly through 1998. Preliminary examination of plume maps revealed that RDX has migrated farther than TNT in spite of the greater aqueous solubility of TNT. This observation supports the case that natural attenuation of TNT is occurring at LAAP.

During routine histological examination, granulomatous lesions were detected, and a low prevalence of Mycobacterium sp. was suspected in the culture system. Fish maintained under experimental and breeding conditions were cultured for acid-fast bacteria. Modified Middlebrook 7H10 medium with albumin, dextrose, and catalase (ADC) enrichment was used to recover mycobacteria from whole-fish homogenates via three isolation procedures. Highest isolation rates were obtained by submerging whole fish in individual bags of modified broth at a 1:10 (weight: volume) dilution for 1 h, then homogenizing the whole fish and plating diluted samples on solid medium using a plate count method. Medaka, ranging in age from 2 to 27 months, were positive for Mycobacterium abscessus with prevalences of 25%-100%. Mean bacterial counts for all groups examined ranged from 6.7 x 10 super(2) to 4.5 x 10 super(8) colony-forming units per gram of fish. Throughout the study, fish remained apparently healthy, exhibited no clinical signs of piscine mycobacteriosis, and suffered no significant mortality.

The experiments were performed at different scales to investigate the validity of scale factors predicted for small-scale frost heave modeling. The working hypothesis was that the developing frost heave forces measured in the different models should, using the predicted scale factors, scale to the same full-scale response. Results from the tests support this hypothesis and provide an indication that the centrifuge modeling technique is applicable to frost heave loading of structures.

While flood damages may be significant locally, they are often insufficient to justify the cost of conventional flood-control structures. Environmental concerns also tend to render these structures unattractive. A new, low-cost structure appears to be well suited to control breakup ice jams on small rivers. It consists of massive sloped blocks, partially buried in riprap, placed across the river adjacent to a natural floodplain. The blocks will arrest a breakup ice run and form a stable, partially grounded ice jam. Trees or boulders on the floodplain retain ice pieces in the river channel while allowing flow to bypass the structure. Large gaps between blocks allow easy fish and canoe passage. Refrigerated hydraulic model tests indicate that the structure should perform well even during severe breakup events. A prototype built in Hardwick, Vt., has performed well during the four mild breakup events experienced to date. Its cost of $3,600/m of river width represents about an order-of-magnitude reduction compared with previous ice-control structures.

Accumulations of broken ice in the upstream approaches to locks and dams can interfere with lock operations and hydropower production. Conveying this ice downstream through dam gates can be difficult because of the low water velocities found in pool areas, and the limited available discharge for ice passage during winter low-flow periods. A physical hydraulic model study, using real ice, investigated the design and operation of submergible gates for ice passage at the U.S. Army Corps of Engineers Starved Rock Lock and Dam on the Illinois Waterway. Alternative gate locations were tested for a range of gate discharges and ice conditions. The effects of hydropower diversions, navigation, and high-flow air screens on ice passage were examined. The study found that, under some ice conditions, submergible gates alone may not be adequate for ice passage. During these times, tow and barge transits through the lock and deflector bubbler operation would need to be coordinated with submergible gate operation to pass ice.

One apparent implication is that water resources planning methods should be modified accordingly. Few of these studies, however, have attempted to account for either the chain of uncertainty in projecting water resources system vulnerability to climate change, or the adaptability of system operation resulting from existing planning strategies. Major uncertainties in water resources climate change assessments lie in a) climate modeling skill; b) errors in regional downscaling of climate model predictions; and c) uncertainties in future water demands. A simulation study was designed to provide insight into some aspects of these uncertainties. Specifically, the question that is addressed is whether a different decision would be made in a reservoir reallocation decision if knowledge about future climate were incorporated (i.e., would planning based on climate change information be justified?). The case study is possible reallocation of flood storage to conservation (municipal water supply) on the Green River, WA. We conclude that, for the case study, reservoir reallocation decisions and system performance would not differ significantly if climate change information were incorporated in the planning process.

The test was initiated with animals less than 2 weeks old (i.e., 425-600 mu m sieved size class). Test endpoints included survival, growth ( mu g dry weight/d), and reproduction (number of neonates /surviving female). Factors with the potential to influence test animal performance (i.e., nontreatment factors) such as artificial sea salts, salinity, food ration, size at test initiation, intraspecific density, sediment grain size, and diet were evaluated. For example, intraspecific densities between 10 and 60 animals/beaker (i.e., 0.18-1.4 animals/cm super(2)) did not affect survival, growth, or reproduction. Similarly, L. plumulosus were tolerant of a wide range of sediment grain sizes with only extremely fine grained (e.g., >75% clay) or coarse grained (e.g., >75% sand) material significantly affecting survival, growth, and reproduction. Test performance criteria included control survival (>80%) and reproduction (production of offspring in all control replicates), and response to a reference toxicant test with cadmium chloride in a control chart format.

Federal water agencies have responsibilities for protecting aquatic ecosystems through their regulatory programs and operations and planning missions. The primary concern of water resources and aquatic ecosystems planning in the United States is on the riparian or floodplain corridors of river systems. In the context of climate change, planning for these systems focusses on adaptation options both for current climate variability and for that engendered by potential climate change. Ecosystems appear to be highly vulnerable to climate change, as described in IPCC reports. Aquatic ecosystems are likely to be doubly affected, first by thermally induced changes of global warming and second by changes in the hydrologic regime. Perhaps as much as any of the issues dealt with in this issue, the evaluation of ecosystems is linked to fundamental questions of criteria as well as to the details of the Federal environmental planning system. That system is a densely woven, interlocking system of environmental protection legislation, criteria and regulations that includes a self-contained evaluation system driven by the National Environmental Policy Act (NEPA) procedural guidelines (United States Council on Environmental Quality, 1978) and Environmental Impact Statement (EIS) requirements. The Corps of Engineers must use both the P&G and the NEPA/EIS system in discharging its responsibilities. If U.S. Federal agencies are to take the lead in formulating and evaluating adaptation options, there needs to be a reexamination of existing evaluation approaches. Among the elements of the P&G that may require rethinking in view of the prospects of global climate change are those relating to risk and uncertainty, nonstationarity, interest rates, and multiple objectives. Within the government planning process, efforts must be made to resolve inconsistencies and constraints in order to permit the optimal evaluation of water-based ecosystems under global climate change. The interrelationships of the two systems are described in this paper, and alternative ways of viewing the planning process are discussed. Strategic planning and management at the watershed level provides an effective approach to many of the issues. Current NEPA/EIS impact analysis does not provide a suitable framework for environmental impact analysis under climate uncertainty, and site-specific water resources evaluation relating to climate change appears difficult at current levels of knowledge about climate change. The IPCC Technical Guidelines, however, provide a useful beginning for assessing the impacts of future climate states.

AN - 79339346; 9334830 AB - A computer program (Q-test) was used to evaluate the combined toxic effects of nerve agent GF and its combined form with sarin (GB/GF) in mice. Efficacy of Jielin Injection, the 2-PAM-containing antidote used successfully in China for the treatment of organophosphate pesticide poisoning, was also evaluated and compared with HI-6 against single and combined poisonings. The two agents were basically additive in toxicity when combined. However, toxic signs (convulsions) appeared later in combined poisoning than after exposure to each agent alone. The protective ratio of Jielin Injection against GF poisoning was low but significantly higher when against poisoning by GB or combined agent. When HI-6 was substituted for 2-PAM, the antidote was more effective against poisoning by both single and combined agents. Results of in vitro reactivation of GF-inhibited human erythrocyte acetylcholinesterase by these oximes agreed with the in vivo antidotal efficacy.

AN - 79162035; 9244332 AB - Concern regarding the use of biological agents--bacteria, viruses, or toxins--as tools of warfare or terrorism has led to measures to deter their use or, failing that, to deal with the consequences. Unlike chemical agents, which typically lead to violent disease syndromes within minutes at the site of exposure, diseases resulting from biological agents have incubation periods of days. Therefore, rather than a paramedic, it will likely be a physician who is first faced with evidence of the results of a biological attack. We provide here a primer on 10 classic biological warfare agents to increase the likelihood of their being considered in a differential diagnosis. Although the resultant diseases are rarely seen in many countries today, accepted diagnostic and epidemiologic principles apply; if the cause is identified quickly, appropriate therapy can be initiated and the impact of a terrorist attack greatly reduced.

AN - 79347249; 9336768 AB - The effect of cyclic adenosine 3',5'-monophosphate (cAMP) on epileptiform activity in rat hippocampal slices was investigated. Bath-applied cAMP reversibly decreased the frequency of extracellularly recorded discharges in the CA3 subfield induced by bethanechol- or theophylline-containing solutions. Because cAMP was presumed to be relatively membrane impermeant, we developed and tested the hypothesis that this cAMP-mediated effect occurred extracellularly through the catabolic conversion of cAMP to 5'-AMP and, in turn, to adenosine, a known inhibitory neuromodulator. Three predictions derived from this catabolic hypothesis were tested. First, blockers of the enzymes involved were predicted to antagonize this effect of cAMP. In contrast, the coapplication of a cAMP-phosphodiesterase inhibitor, 3-isobutyl-1-methylxanthine (IBMX), or a 5'-nucleotidase inhibitor, adenosine 5'-[alpha, beta-methylene] diphosphate (AMP-CP), enhanced the cAMP-induced suppressive effect. Second, the nonhydrolyzable cAMP analogs, dibutyryl- and 8-bromo-cAMP, were predicted to be ineffective. Low concentrations (5-40 microM) of these two derivatives, however, also suppressed bethanechol-induced discharges, while, at a higher concentration (100 microM), both analogs increased discharge frequencies. Third, enzymatic catabolism of adenosine was predicted to antagonize cAMP's effect, but coapplying adenosine deaminase (10 U/mL) did not diminish this action. Because these data did not support the catabolic hypothesis, other, as yet undefined, mechanisms must be responsible for the discharge-suppressant effect of cAMP.

AN - 79302324; 9306315 AB - An automated procedure for estimation of blood cholinesterase activities was evaluated and used to determine baseline cholinesterase activities in rabbits. In addition, the kinetics of cholinesterase inhibition and recovery from diazinon challenge were determined by use of this procedure. The procedure developed is a modification of the colorimetric Ellman technique, adapted for use with the Instrumentation Laboratory Multistat III Plus Centrifugal Analyzer. The substrate used in this technique was acetylthiocholine. Baseline cholinesterase activities in domestic rabbits were plasma cholinesterase, 360 mU/ml; red blood cell cholinesterase, 2,658 mU/ml; and whole blood cholinesterase, 1,332 mU/ml. Rabbits were challenged with 0.3 LD50 (40 mg/kg) of diazinon, and blood samples were obtained at hourly, then daily intervals. Cholinesterase activity in these samples was determined to monitor the effect of the cholinesterase inhibitor diazinon in vivo, as estimated by the Multistat III Plus Centrifugal Analyzer procedure. Plasma cholinesterase activity decreased to 4% within 6 h, whereas red blood cell cholinesterase activity decreased to 51%. By 10 days, plasma and red blood cell cholinesterase activities had returned to 100 and 91%, respectively, of pre-challenge activities.

AN - 79222587; 9263123 AB - A novel computational approach was examined for predicting epitopes from primary structures of the seven immunologically distinct botulinum neurotoxins (BoNT/A-G) and tetanus toxin (TeTX). An artificial neural network [Rost and Sander (1994), Proteins 20, 216] was used to estimate residue solvent accessibilities in multiple aligned sequences. A similar network trained to predict secondary structures was also used to examine this protein family, whose tertiary fold is presently unknown. The algorithm was validated by showing that it was 80% accurate in determining the secondary structure of avian egg-white lysozyme and that it correctly identified highly solvent-exposed residues that correspond to the major contact regions of lysozyme-antibody cocrystals. When sequences of the heavy (H) chains of TeTX and BoNT/A-G were analyzed, this algorithm predicted that the most highly exposed regions were clustered at the sequentially nonconserved N- and C-termini [Lebeda and Olson (1994), Proteins 20, 293]. The secondary structures and the remaining highly solvent-accessible regions were, in contrast, predicted to be conserved. In experiments reported by others, H-chain fragments that induced immunological protection against BoNT/A overlap with these predicted most highly exposed regions. It is also known that the C-terminal halves of the TeTX and BoNT/A H-chains interfere with holotoxin binding to ectoacceptors on nerve endings. Thus, the present results provide a theoretical framework for predicting the sites that could assist in the development of genetically engineered vaccines and that could interact with neurally located toxin ectoacceptors. Finally, because the most highly solvent-exposed regions were not well conserved, it is hypothesized that nonconserved, potential contact sites partially account for the existence of different dominant binding regions for type-specific neutralizing antibodies.

AN - 79152969; 9234711 AB - The RAD6 gene of Saccharomyces cerevisiae encodes a ubiquitin-conjugating enzyme required for postreplicational repair of UV-damaged DNA and for damage-induced mutagenesis. In addition, Rad6 functions in the N end rule pathway of protein degradation. Rad6 mediates its DNA repair role via its association with Rad18, whose DNA binding activity may target the Rad6-Rad18 complex to damaged sites in DNA. In its role in N end-dependent protein degradation, Rad6 interacts with the UBR1-encoded ubiquitin protein ligase (E3) enzyme. Previous studies have indicated the involvement of N-terminal and C-terminal regions of Rad6 in interactions with Ubr1. Here, we identify the regions of Rad6 and Rad18 that are involved in the dimerization of these two proteins. We show that a region of 40 amino acids towards the C terminus of Rad18 (residues 371 to 410) is sufficient for interaction with Rad6. This region of Rad18 contains a number of nonpolar residues that have been conserved in helix-loop-helix motifs of other proteins. Our studies indicate the requirement for residues 141 to 149 at the C terminus, and suggest the involvement of residues 10 to 22 at the N terminus of Rad6, in the interaction with Rad18.

Soil samples collected during site investigations specifically for characterizing the extent of VOC contamination are held at 4 degree C for up to 14 days before analysis. The acceptance of refrigerated storage as an effective method of sample preservation is questionable in light of recent studies, which show losses of aromatic hydrocarbons in soil samples held in vapor-tight vessels. This paper presents an abbreviated study assessing the concentration stability of 24 individual VOCs plus gasoline in soil samples. These samples were held for up to 28 days at room temperature (22 degree C), with and without a chemical preservative, or refrigerated (4 degree C). The objective was to compare the effect of temperature on the rate of biodegradation and to determine the effectiveness of using a chemical preservative. Sodium bisulfate (NaHSO sub(4)) was chosen as the chemical preservative because of its low toxicity, compatibility with field operations, and its success in a study of VOC concentration stability in aqueous matrices.

Galacturonic acid, previously reported as a repeat unit of PS-7, was not found in purified PS-7. The yield of PS-7 varied with physiological conditions, such as concentration of carbon source and initial pH of medium, but the molar ratio of rhamnose to glucose stayed within 1.0 to 4.6-5.1. B. indica utilized glucose and some glucose analogs as carbon sources and produced exopolymers, although there was no direct incorporation of these sugars into PS-7.

Recently, based almost exclusively on blast sound research, a new method which replaces the C-weighted day-night average sound level has been recommended and incorporated into a new American National Standard. In this new method, as in the previous method, sonic boom sounds are included and assessed in a like manner to blast sounds. However, while available evidence suggested that in an indoor setting sonic boom could be treated in a similar fashion to blast sounds, experimental evidence was lacking. The purpose of the study reported herein was to provide the lacking comparison data. The study tested if the responses of subjects to sonic booms were consistent with previous blast response data presented by Schomer, since these were the data which formed the basis for the new method. A key factor in the design of this study was the presentation of real blasts and booms to subjects situated in real structures in the field. The study was performed as a paired-comparison test with the same control sound being used in this study as had been used in all the previous blast research that formed the basis for the new assessment method. In this new study, 232 subjects each judged 20 booms and 30 blast sounds. The new data resulting from this study show good general agreement with the previous data reported by Schomer. However, there is an indication that for the same C-weighted sound exposure level, a boom is slightly more annoying than a blast.

An ordinance for King County, Wash., is used to illustrate the challenges of implementing such restrictions and their resulting implications for bridge design. The evaluation is performed by comparing the King County floodplain regulation to similarly restrictive regulations in other states and counties and to other zero tolerance regulations. The bridge design and construction costs associated with the ordinance since 1990 are also reviewed, as are procedures for obtaining variances from the zero-rise criterion. It was found that in King County the zero-rise criterion compounds the already existing complexities of bridge design requirements. Important differences between the King County regulations and zero-rise requirements in other locales were found to include: freedom from substantial clearance requirements, pier-in-channel prohibitions (unrelated to backwater considerations), exemptions for replacement in-kind, lenient permitting processes for rises where no damage is anticipated, and the ability of approach roads to cause flood. The zero-rise ordinance was found to increase bridge design and construction costs by about 40% on the bridges for which backwater was a constraint. Variance procedures were as impractical in other locales as in King County, but mitigation options, such as the purchase of flooding easements, were more frequently pursued.

In contrast to the findings of a previous report, two different, biologically active preparations of CPE had no mitogenic effects on PBMC. Furthermore, PBMC incubated with various concentrations of CPE did not elicit interleukin-1, interleukin-2, gamma interferon, or tumor necrosis factor alpha or beta, which are cytokines commonly associated with superantigenic stimulation. However, CPE did cause a dose-related release of interleukin-6 from PBMC cultures.

AN - 79129226; 9217314 AB - The effect of blast overpressure on visual system pathology was studied in 14 male Sprague-Dawley rats weighing 360-432 g. Blast overpressure was simulated using a compressed-air driven shock tube, with the aim of studying a range of overpressures causing sublethal injury. Neither control (unexposed) rats nor rats exposed to 83 kiloPascals (kPa) overpressure showed evidence of visual system pathology. Neurological injury to brain visual pathways was observed in male rats surviving blast overpressure exposures of 104-110 kPa and 129-173 kPa. Optic nerve fiber degeneration was ipsilateral to the blast pressure wave. The optic chiasm contained small numbers of degenerated fibers. Optic tract fiber degeneration was present bilaterally, but was predominantly ipsilateral. Optic tract fiber degeneration was followed to nuclear groups at the level of the midbrain, midbrain-diencephalic junction, and the thalamus where degenerated fibers arborized among the neurons of: (i) the superior colliculus, (ii) pretectal region, and (iii) the lateral geniculate body. The superior colliculus contained fiber degeneration localized principally to two superficial layers (i) the stratum opticum (layer III) and (ii) stratum cinereum (layer II). The pretectal area contained degenerated fibers which were widespread in (i) the nucleus of the optic tract, (ii) olivary pretectal nucleus, (iii) anterior pretectal nucleus, and (iv) the posterior pretectal nucleus. Degenerated fibers in the lateral geniculate body were not universally distributed. They appeared to arborize among neurons of the dorsal and ventral nuclei: the ventral lateral geniculate nucleus (parvocellular and magnocellular parts); and the dorsal lateral geniculate nucleus. The axonopathy observed in the central visual pathways and nuclei of the rat brain are consistent with the presence of blast overpressure induced injury to the retina. The orbital cavities of the human skull contain frontally-directed eyeballs for binocular vision. Humans looking directly into an oncoming blast wave place both eyes at risk. With bilateral visual system injury, neurological deficits may include loss or impairments of ocular movements, and of the pupillary and accommodation reflexes, retinal hemorrhages, scotomas, and general blindness. These findings suggest that the retina should be investigated for the presence of traumatic or ischemic cellular injury, hemorrhages, scotomas, and retinal detachment.

AN - 79129165; 9217311 AB - Blast overpressure (BOP) or high energy impulse noise, is the sharp instantaneous rise in ambient atmospheric pressure resulting from explosive detonation or firing of weapons. Blasts that were once confined to military and to a lesser extent, occupational settings, are becoming more universal as the civilian population is now increasingly at risk of exposure to BOP from terrorist bombings that are occurring worldwide with greater frequency. Exposure to incident BOP waves can cause auditory and non-auditory damage. The primary targets for BOP damage are the hollow organs, ear, lung and gastrointestinal tract. In addition, solid organs such as heart, spleen and brain can also be injured upon exposure. However, the lung is more sensitive to damage and its injury can lead to death. The pathophysiological responses, and mortality have been extensively studied, but little attention, was given to the biochemical manifestations, and molecular mechanism(s) of injury. The injury from BOP has been, generally, attributed to its external physical impact on the body causing internal mechanical damage. However, a new hypothesis has been proposed based on experiments conducted in the Department of Respiratory Research, Walter Reed Army Institute of Research, and later in the Department of Occupational Health, University of Pittsburgh. This hypothesis suggests that subtle biochemical changes namely, free radical-mediated oxidative stress occur and contribute to BOP-induced injury. Understanding the etiology of these changes may shed new light on the molecular mechanism(s) of injury, and can potentially offer new strategies for treatment. In this symposium. BOP research involving auditory, non-auditory, physiological, pathological, behavioral, and biochemical manifestations as well as predictive modeling and current treatment modalities of BOP-induced injury are discussed.

AN - 79117472; 9217317 AB - Blast overpressure (BOP) is the abrupt, rapid, rise in atmospheric pressure resulting from explosive detonation, firing of large-caliber weapons, and accidental occupational explosions. Exposure to incident BOP waves causes internal injuries, mostly to the hollow organs, particularly the ears, lungs and gastrointestinal tract. BOP-induced injury used to be considered of military concern because it occurred mostly in military environments during military actions or training, and to a lesser extent during civilian occupational accidents. However, in recent years with the proliferation of indiscriminate terrorist bombings worldwide involving civilians, blast injury has become a societal concern, and the need to understand the biochemical and molecular mechanism(s) of injury, and to find new and effective methods for treatment gained importance. In general, past BOP research has focused on the physiological and pathological manifestations of incapacitation, thresholds of safety, and on predictive modeling. However, we have been studying the molecular mechanism of BOP-induced injury, and recently began to have an insight into that mechanism, and recognize the role of hemoglobin released during hemorrhage in catalyzing free radical reactions leading to oxidative stress. In this report we discuss the biochemical changes observed after BOP exposure in rat blood and lung tissue, and propose a biochemical mechanism for free radical-induced oxidative stress that can potentially complicate the injury. Moreover, we observed that some antioxidants can interact with Hb oxidation products (oxy-, met- and oxoferrylHb) and act as prooxidants that can increase the damage rather than decrease it.

AN - 79093440; 9204869 AB - The pH-dependence and solvent isotope effects of dealkylation in diastereomeric adducts of Electric eel (Ee) and fetal bovine serum (FBS) acetylcholinesterase (AChE) inactivated with P(-)C(+) and P(-)C(-) 2-(3,3-dimethylbutyl) methylphosphonofluoridate (soman) were studied at 4.0 +/- 0.2 degrees C. The rate constant versus pH profiles were fit to a bell-shaped curve for all adducts. Best fit parameters are pK1 4.4-4.6 and pK2 6.3-6.5 for Ee AChE and pK1 4.8-5. 0 and pK2 5.8 for FBS AChE. The pKs are consistent with catalytic participation of the Glu199 anion and HisH+440. Maximal rate constants (kmax) are 13-16 x 10(-3) s-1 for Ee AChE and 8 x 10(-3) s-1 for FBS AChE. The solvent isotope effects at the pH maxima are 1.1-1.3, indicating unlikely proton transfer at the enzymic transition states for the dealkylation reaction. Slopes of log rate constant versus pH plots are near 1 at 25.0 +/- 0.2 degrees C between pH 7.0 and 10.0. In stark contrast, the corresponding adducts of trypsin are very stable even at 37.0 +/- 0.2 degrees C. The rate constants for diastereomers of soman-inhibited trypsin at 37.0 +/- 0.2 degrees C are pH independent and approximately 10(4) times smaller than kmax for analogous adducts with AChE. Dealkylation in soman-inhibited AChEs is estimated to occur at >10(10) times faster than a plausible nonenzymic reaction. Up to 40% of the catalytic acceleration can be attributed to an electrostatic push, and an electrostatic pull provides much of the balance. The results of this work together with results of a product analysis by Michel et al. (1969) can be explained by an initial and rate-determining methyl migration from Cbeta to Calpha. This is driven by the high electron density of residues (Glu199 and Trp84) at a crowded active site and may be concerted with C-O bond breaking. The positive charge at the rate-determining transition state is distributed between Cbeta and His440. A tertiary carbocation may have a fleeting existence before it is trapped by water or neighboring electrons which is likely to be promoted by Glu199 as the proton acceptor.

AN - 79235765; 9268607 AB - The extent to which cardiorespiratory infirmity and other sublethal effects of saxitoxin (STX) and tetrodotoxin (TTX) can be reversed by 4-aminopyridine (4-AP) was investigated in guinea pigs chronically instrumented for the concurrent electrophysiological recordings of electrocorticogram (ECoG), diaphragmatic electromyogram (DEMG), Lead II electrocardiogram, and neck skeletal muscle electromyogram. Animals were intoxicated with either STX or TTX (2 and 3 microg/kg, im) to produce a state of progressive cardiorespiratory depression (depicted by decreasing DEMG amplitude, bradypnea, and bradycardia). At the point where cardiorespiratory performance was most seriously compromised (approximately 30 min posttoxin), 4-AP (1 or 2 mg/kg, im) was administered. The therapeutic effect of 4-AP was striking in that, within minutes, the toxin-induced diaphragmatic blockade, bradypnea, bradycardia, and depressed cortical activity were all restored to a level either comparable to, or surpassing, that of control. The optimal 4-AP dose level was determined to be 2 mg/kg (im) based on analyses of cardiorespiratory activity profiles throughout the course of intoxication and 4-AP treatment. At the dose levels (either 1 or 2 mg/kg) used to restore ventilatory function and cardiovascular performance, 4-AP produced no sign of seizures and convulsions. Although less serious secondary effects such as cortical excitant/arousal effect (indicated by ECoG power spectral analysis) and transient periods of skeletal muscle fasciculation were observed, these events were of minor concern particularly in view of the remarkable therapeutic effects of 4-AP.

AN - 79170386; 9248007 AB - The ability of N,N,N',N'-tetrakis (2-pyridylmethyl)-ethyenediamine (TPEN) to protect against botulinum neurotoxin (BoNT) A and B was examined in vivo in mice. To determine the protective efficacy of TPEN, mice were injected i.p. with TPEN as a single bolus or as multiple injections 30 min before and 0, 2, 4 and 6 hr following i.v. challenges with BoNT-A or -B. TPEN treatment did not alter the 24 hr lethality of BoNT but did produce a significant delay in the time to death. For a moderate dose of serotype A (20 LD50), five divided doses of TPEN prolonged the time to death from 7.8 +/- 0.4 hr to 9.9 +/- 0.5 hr. For serotype B, examined under comparable conditions, the prolongation of the time to death was from 6.1 +/- 0.2 hr to 9.4 +/- 0.6 hr. The range of TPEN doses that could be examined in vivo was limited by its acute toxicity. Although low doses of TPEN ( or = 30 mg/kg) led to ataxia, loss of coordination, convulsions and death in 20.3 min or less. In clonal NG108-15 cells, TPEN was found to produce cytotoxicity as revealed by increases in the secretion of the marker enzyme lactate dehydrogenase (LDH), and enhanced reactivity with the vital dye trypan blue. From LDH concentration-response data determined 24 hr after addition of TPEN, the threshold concentration for observing cytotoxicity was 10 microM and the IC50 was 19.8 microM. At the highest TPEN concentration tested (100 microM), cytotoxicity was detected 8 hr after TPEN addition and increased in severity over a 3 day period. The cytotoxicity in NG108-15 cells appears to be distinct from the rapid-onset toxicity observed in whole animals. These results suggest that TPEN may be of potential benefit in delaying the lethal actions of BoNT-A and -B, but its use is limited by its initial and delayed toxicity. Since the therapeutic and toxic actions of TPEN are both related to zinc chelation, the use of TPEN would need to be restricted to low doses as part of a combination therapy.

AN - 79103002; 9202957 AB - Pretreatment with aminophylline has been shown to protect against various types of acute lung injury. Mechanisms responsible for protection are multifactorial but are thought to involve upregulation of cAMP. While previous studies focused on pretreatment, the present investigation examined post-treatment in rabbits following exposure to a lethal dose of the oxidant gas phosgene. Rabbits, 2-3 kg, were exposed to a cumulative dose of phosgene to attain a c x t exposure effect of 1500 ppm.min. Lungs were isolated in situ and perfused for 90-100 min after exposure with Krebs-Henseleit buffer at 40 mL/min. Pulmonary artery pressure (Ppa), tracheal pressure (Pt), and lung weight gain (lwg) were measured continuously. Leukotrienes C4/D4/E4 were measured in the perfusate every 20 min during perfusion. At the immediate conclusion of the experiment, lung tissue was frozen in liquid N2 and analyzed for reduced GSH, GSSG, cAMP, and lipid peroxidation (TBARS). Post-treatment with aminophylline 80-90 min after exposure significantly lowered Ppa, Pt, and lwg. Aminophylline significantly reduced TBARS and perfusate LTC4/D4/E4, and prevented phosgene-induced decreases in lung tissue cAMP. These data suggest that protective mechanisms observed with aminophylline involve decreased LTC4/D4/E4-mediated pulmonary capillary permeability and attenuated lipid peroxidation.

The silt particles embedded in the GRIP basal ice result from the reworking of the subglacial till unit overlying granitic bedrock at GISP 2, 28 km to the east. This implies that the till unit is continuous in Central Greenland. The silt particles embedded in the GISP 2 basal ice result from local erosion of the granitic bedrock. An erratic dolerite boulder in the subglacial till at GISP 2 is from a mafic dyke that can be related to the Carolinidian mid-Proterozoic fold belt exposed in East Greenland. This study supports the hypothesis that the Greenland Ice Sheet in the Summit area did not result from in situ growth from local snowbanks. The composition of the dolerite boulder points to East Greenland as the most probable source region for the ice sheet.

Clonal expansion primarily by stolons provides Eurasian watermilfoil with a means of localized spread, while intermediate distance expansion is provided by fragment production. These mechanisms of spread were studied in outdoor ponds at Lewisville, Texas, and the results were compared to a 1987 Lake George, New York study. In both studies, the predominant mechanism of vegetative propagation was stolon production. In the southern study, stolon production accounted for 74% of areal expansion while fragments accounted for 26%. Although plant establishment in new quadrats by fragments was not as successful an expansion strategy as stolons, this study determined that 46% of the fragments which settled onto the substrate successfully established and thus provided the species with a significant mechanism for a more rapid rate of population expansion.

Worms were fed one of three food rations: 0.25x, 1.0x, and 6.0x. The 1.0x ration was composed of 4 mg TetraMarin /worm/week and 2 mg alfalfa/worm/week. Worms in each food ration were exposed to one of two sediments: a clean control sediment collected from Sequim Bay, Washington, USA (SC) or a contaminated sediment collected from Black Rock Harbor near Bridgeport, Connecticut, USA (BRH) that was diluted with SC such that the final concentration of contaminated sediment was 12%. Survival and growth were monitored every 2 weeks for 8 weeks. Sediment treatment and food ration had strong effects on survival and growth patterns in N. arenaceodentata. Most of the mortality within any given treatment combination occurred during the first 2 weeks of the experiment. This decline in survival was greatest for worms exposed to BRH. Survival was significantly lower for worms in BRH compared to SC at the 0.25x and 1.0x ration levels. Survival was not reduced for worms in BRH compared to SC at the 6.0x ration level. Worm size during the course of the experiment was positively related to ration level. Significantly reduced size in BRH worms was observed at each monitoring period within the 0.25x and 1.0x rations, but only at weeks 6 and 8 for the 6.0x ration level. The percent difference in size between worms exposed to BRH and SC, when those worms were fed the 0.25x or 1.0x rations, ranged between 55 and 66%. The percent difference in size observed between BRH and SC worms fed the 6.0x ration was much smaller (9-17%). The results of this study demonstrate that food ration has a strong influence on observed toxicity in N. arenaceodentata. The importance of food ration effects on toxicity must be considered while designing chronic sublethal bioassays. To ensure the relevance of bioassay results, the food ration used during a chronic bioassay should produce a pattern of growth in control animals that is similar to patterns of growth observed in nature.

Worms were exposed to contaminated sediment collected from Black Rock Harbor (BRH) near Bridgeport, Connecticut, USA. This sediment was diluted with clean control sediment to result in five experimental treatments: 0, 25, 50, 75, and 100% BRH. Three exposure scenarios were employed: (1) a 4-week exposure beginning with newly emerged juveniles (EJ-4w), (2) a 7-week exposure beginning with newly emerged juveniles (EJ-7w), and (3) a 4-week exposure beginning with 3-week-old juveniles (3WO-4w). Six measures of worm size were recorded at the conclusion of each exposure to evaluate differences among measurement endpoints. Survival was significantly reduced at the 25% BRH level for the EJ-7w scenario and at the 100% BRH level for the EJ-4w and 3WO-4w scenarios. Growth was significantly reduced at the 25% BRH level in each exposure scenario. Estimates based on the calculated minimum detectable difference indicated that considerably lower concentrations of BRH (6-10%) should be distinguishable by measuring effects on Neanthes growth. Worm size measured in terms of projected area, dry weight, and ash-free dry weight provided the most sensitive measures of effects. Increasing the length of exposure from 4 to 7 weeks and initiating exposures with emergent juveniles rather than 3-week-old worms increased the sensitivity of the bioassay. The results of this study demonstrate that N. arenaceodentata is sensitive to the presence of sediment-associated contaminants and that test animal age, duration of exposure, and choice of endpoint can have a large effect on the magnitude of the toxic response observed.

AN - 79102658; 9201909 AB - Dendrotoxin K (DTXK) is a 57-residue protein from mamba venom that blocks certain non-inactivating, voltage-activated K+ currents in neurones. In order to pinpoint the residues responsible for its specificity, structure-activity relations of DTX(K) were investigated by mutagenesis. A previously cloned gene encoding this toxin [Smith et al. (1993) Biochemistry 32, 5692-5697] was used to make single mutations; after expression in Escherichia coli as fusion proteins and enzymatic cleavage of the conjugates isolated from the periplasmic space, nine toxins were purified. Structural analysis of the native DTXK and representative mutants by circular dichroism showed that no significant differences were detectable in their folded structures. The biological activity of the mutants, which contained alterations of positively charged and other amino acids, was determined from their abilities to compete for the binding of 125I-labeled DTX(K) to K+ channels in synaptic plasma membranes from rat cerebral cortex. Mutants with residues substituted in the alpha-helix near the C-terminus (R52A or R53A) yielded binding parameters similar to those of wild-type and native DTX(K). In the case of the beta-turn (residues 24-28), however, altering single amino acids reduced binding to the high-affinity site of K+ channels, with the rank order of decreases being K26A >> W25A > K24A = K28A. Also, substitutions made in the 3(10)-helix (residues 3-7), a region located close to the beta-turn, produced equivalent effects (K3A > K6A). Thus, it is deduced that residues in the distorted beta-turn and neighboring 3(10)-helix of DTX(K) are critical for its interaction with neuronal K+ channels.

Of this, between 30 to 60% of the electric costs are due to summer air conditioning loads. A reduction in electric consumption during air conditioning seasons can lead to utility savings. An opportunity also exists to lessen the environmental impact caused by old and inefficient equipment by replacing it with more efficient and advanced technology equipment. The US Army Construction Engineering Laboratories has been investigating advanced gas cooling technologies as a means of reducing the energy costs at DOD fixed installations. This technology includes absorption and gas engine-driven chillers as replacement units for existing electric-driven chillers and desiccant units displacing dehumidification by electric-driven chillers. As a result of implementing this new technology, overall emissions are reduced by burning natural gas on site as opposed to producing electricity remotely (via coal, oil or natural gas) and distributing it to bases as an energy source for driving electric-driven chillers. This paper will review gas cooling technologies and report on the predicted reduction of SO sub(X), NO sub(X) and particulate emissions at several project installations throughout the United States. The analysis was performed using the Renewable Energy Engineering Program (REEP) software package.

New boiler technology may help improve the Army's ability to supply fuels, meet demand, and comply with environmental regulations. The U.S. Army Construction Engineering Research Laboratory (USACERL) is conducting a demonstration of a cyclonic a low emission natural gas boiler. The demonstration will occur at Watervliet Arsenal, NY (WVA) at their central power plant, Building 136. The demonstration boiler will be a 100,000 pounds per hour (pph) steam boiler and will use a new low emission technology developed by the Gas Research Institute. This technology is cyclonic combustion, which may reduce boiler NOx (nitrogen oxide) emissions to 30 ppm (parts per million) and increase combustion efficiency to 82%. The objective of this demonstration is to research the field implementation of new boiler technology at Army installations so that utilization of low emission technology can be expanded.

AN - 79039457; 9176551 AB - Composting is being explored as a means to remediate 2,4,6-trinitrotoluene (TNT) contaminated soils. This process appears to modify TNT and to bind it to organic matter. The health hazards associated with dusts generated from such materials cannot be predicted without knowing if the association between TNT residues and compost particulate is stable in biological systems. To address this question, single doses of [14C]-TNT, soil spiked with [14C]-TNT, or compost generated with [14C]-TNT-spiked soils were administered to rats by intratracheal instillation. The appearance of 14C in urine and tissues was taken as an indication of the bioavailability of TNT residues from compost particles. In rats instilled with neat [14C]-TNT, about 35% of the 14C dose appeared in urine within 3 d. The 14C excreted in urine by these rats decreased rapidly thereafter, and was undetectable by 4 wk after treatment. Similar results were obtained with soil-treated rats. In contrast, after treatment with [14C]-TNT-labeled compost, only 2.3% of the total 14C dose appeared in urine during the first 3 d. Low levels of 14C continued to be excreted in urine from compost-treated rats for more than 6 mo, and the total amount of 14C in urine was comparable to that in TNT-treated animals. Determination of the radiolabel in tissues showed that 14C accumulated in the kidneys of rats treated with labeled compost but not in rats treated with [14C]-TNT or [14C]-TNT-spiked soil. These results indicate that the association between TNT and particulate matter in compost is not stable when introduced into the lungs. Accumulation of 14C in kidneys suggests the presence of a unique TNT residue in compost-treated rats. The rate of excretion and tissue disposition of 14C in rats treated with TNT-spiked soil indicate that TNT in soil is freely available in the lungs.

AN - 79185274; 9249650 AB - Sugar meals of plant origin are an important component of the sand fly diet. We show that sugar solution baits have potential as vehicles for phlebotomine sand fly control. In the laboratory, adult Phlebotomus duboscqi Neveu-Lemaire and Sergentomyia schwetzi (Adler, Theodor, and Parrot) that have consumed an aqueous sucrose solution containing Bacillus sphaericus Neide toxins and are subsequently eaten by larvae produce significant larval death (P < 0.01). In the field, when vegetation near animal burrows and eroded termite mounds was sprayed with sucrose solution with or without incorporation of the larval toxicant B. sphaericus, 40% of female sand flies fed in situ. Dispersing B. sphaericus-carrier sand flies caused significant larval mortality (P < 0.01) in resting and breeding sites in animal burrows 10-30 m from the sprayed vegetation for 2-12 wk posttreatment. Also, adult sand fly populations breeding and resting inside animal burrows were significantly reduced (P < 0.01) following direct application of the sucrose/B. sphaericus solution to the burrow entrances. This control effect lasted 4-10 wk post-treatment. The effect was not seen for sand fly populations breeding and resting inside eroded termite mounds. This approach may be useful for the application of biological control agents against phlebotomine sand flies in biotypes where larvae and adults use the same habitats.

AN - 79070892; 9183161 AB - The purpose of this study was to determine the prevalence of smokeless tobacco use and clinical leukoplakia in a specific military population. Two hundred fourteen soldiers participated in this study. Each participant completed a questionnaire-type survey regarding tobacco use and received an annual-type dental examination that included extra-oral and intra-oral examination of hard and soft tissues and counseling regarding the risks associated with the use of tobacco. More than 50% of the participants were between the ages of 18 and 24. Survey response indicated that 7.0% used smokeless tobacco, 29.0% smoked cigarettes, and 7.9% used both cigarettes and smokeless tobacco. Leukoplakia was seen in 4 of the current smokeless tobacco users. Difficulty in cessation was experienced by 10 of 32 smokeless tobacco users; 5 continue to use smokeless tobacco. Due to the concentration of users in the 18 to 24 age group, efforts toward detection and reduction of smokeless tobacco use should be focused on junior ranks and younger age groups.

AN - 79045264; 9180204 AB - The purpose of this study was to compare an experimental regimen of atovaquone plus proguanil with the standard regimen of quinine plus tetracycline for the treatment of uncomplicated falciparum malaria. The study was designed as an open, randomized study of men presenting with symptoms of uncomplicated malaria and thick-smear slide confirmation of parasitemia (1000-100,000 ring forms/microL). Subjects were hospitalized for 28 days to insure medication compliance and to rule out the possibility of reinfections. With 77 patients in each group, the cure rates were 98.7% and 100% for atovaquone plus proguanil and quinine plus tetracycline, respectively. The parasite clearance times (mean, 56 h) and fever clearance times (mean, 19 h) were significantly shorter in the atovaquone plus proguanil group, and there were significantly fewer side effects in the atovaquone plus proguanil group. Atovaquone plus proguanil is an efficacious, easily administered, safe regimen for the treatment of uncomplicated, multidrug-resistant falciparum malaria in Brazil.

The method is simple and robust, and can easily be included in standard finite element and finite difference heat transfer programs. Simulations of one- and two-dimensional heat transfer in soil with an inclusion of sand were done to investigate the disruption in frost and thaw penetration due to the presence of a dry, low thermal conductivity sand. The thermal properties of the surrounding material were assumed to be those of a silty soil at various moisture contents. The dependence of frost depth on weather conditions was investigated by using four different (coldest, cold, warm, warmest) winter-long temperature histories for the soil surface boundary condition; these were derived from measured soil temperatures at a Vermont site. With details depending on the moisture content of the soil, significant effects on the time history of frost penetration were observed when a wide sand inclusion is present. Frost penetration actually proceeds more rapidly through the sand at first because it is dry and, therefore, has a lower latent heat and heat capacity; initial frost depth is greater when a sand inclusion is present. Freezing of the soil below the sand inclusion is subsequently impeded by the slow removal of heat at the base of the sand as a consequence of its lower thermal conductivity; thus, the maximum frost depth is greater in soil without a sand inclusion. The influence of the width of the sand inclusion and its effective lateral range are also considered.

Laboratory flume tests were carried out by initially inoculating fluid-like clayey muds with dyes used as generic constituent surrogates. For each combination of dye and mud, dissolved and particle-bound release fluxes were determined as functions of wave and mud properties by numerically modeling constituent and sediment transport. In the absence of sediment entrainment the dissolved constituent flux in the interfacial diffusive sublayer is mainly governed by the rate of diffusion in mud heaving under wave action and by the rate of mass transfer across the sublayer. The diffusion coefficient in mud appears to be related to the rate of wave energy dissipation by internal friction, and the sublayer diffusion coefficient is found to follow a Chilton-Colburn type relationship for boundary layer mass transfer. When entrainment of sediment and associated pore water occurred, particle-bound constituent release became important. However, partial return of the entrained sediment and water due to redeposition of mud floes caused the net rate of constituent release to the ambient water column to be a comparatively small fraction of the total rate of release. This observation implies that transport models for nutrients and contaminants must accurately account for the two-way interfacial exchange of sediment and water to avoid a possible overprediction of constituent release at the mud boundary.

One mitigation measure that might be used in advance of ice breakup is aerial dusting of the ice, which enhances the natural weakening process. Because there may be limited time in which to organize and implement advance measures for ice jams, dusting operations should be planned beforehand. This paper provides a brief overview of the physical processes involved in ice dusting and discusses important aspects of a dusting plan. Experiences from two dusting programs in Nebraska were used as the basis for developing a set of guidelines for planning dusting operations. A spreadsheet for estimating dusting costs was also developed, and is presented with actual data from a 1994 dusting operation.

Overall, zebra mussels removed > 70% of the suspended seston and > 80% of the total chlorophyll a input to the microcosms. Declines in organic nitrogen in microcosms were accompanied by density-dependent increases in nitrate-nitrite nitrogen. We suggest that micro flora associated with the sediments in the microcosms were transforming ammonium nitrogen, which is an excretory product of zebra mussels, into nitrate nitrogen. Declines in total phosphorus in the microcosms also coincided with density-dependent increases in the concentration of soluble reactive phosphorus and its rate of regeneration, suggesting enhanced nutrient cycling via excretion. Calculated rates of soluble phosphorus regeneration due to zebra mussel activity ranged from 0.3 to 2.5 mg m super(-2) d super(-1) at mussel densities ranging between 170 to 1300 individuals m super(-2). Phosphorus regeneration by zebra mussels could have important implications for the phosphorus economy of many lakes and rivers which have been invaded by this organism.

Characterization and analysis of toxic and biologically active molecules, pathogenic and non-pathogenic organisms, diagnosis and treatment of diseases, identification and therapy for genetic disorders, biotechnology, bioremediation, and recognition as well as projection of potential threats to human health are some of the areas in which MS and MS/MS methodologies have been applied extensively. Electrospray (ESI), fast atom bombardment (FAB), and matrix assisted laser desorption (MALDI) ionization methods in combination with MS and MS/MS techniques were applied to measure the molecular masses of proteins using femtomole quantities of the intact molecules. Samples were introduced into the ionization source either directly or after liquid chromatographic (HPLC) or capillary zone electrophoretic (CZE) separation for measuring molecular masses. Simple chemical transformation, derivatization, and enzymatic degradations of a few nanomoles of the intact molecules followed by tandem mass spectrometric (MS/MS) analysis of the products resulted in deriving the total amino acid sequences of the intact molecule. Location of the disulfide bonds could also be identified by a similar approach using 1-2 nanomoles of the proteins. Bacterial pathogens can be detected up to the strain level and distinguished from their non-pathogenic counterparts by the MALDI-MS analysis of either bacterial proteins or the intact whole cells. Distinction of closely related bacteria could thus be accomplished by mass spectrometric methods with ease, which was not possible earlier. Methods described in this report can easily be adopted for the detection, identification, and characterization of any proteinaceous toxins, antibodies, bacterial and viral pathogens.

Two widely used techniques for making hydrophytic vegetation decisions involve dominance ratios (i.e., the percentage of dominant species that are rated obligate (OBL), facultative wetland (FACW), and facultative (FAC)) and prevalence indices (i.e., the weighted-average wetland indicator status of all plants present). We sampled 338 vegetation plots on sites throughout the United States and calculated the dominance ratio and a plot-based prevalence index for each plot. We found that hydrophytic vegetation decisions based on the two methods disagreed on 16% of field plots. Analysis of simulated plot data (n = 80,000) indicated that frequencies of disagreement increase as vegetation complexity (i.e., number of strata and number of species per stratum) increases. We conclude that the two methods for hydrophytic vegetation decisions disagree too often to be considered equivalent. Additional studies are needed in different biogeographic regions and plant community types to determine the conditions under which prevalence indices, dominance ratios, or some other treatment of vegetation data provide more reliable indicators of wetland vegetation.

AN - 79217919; 9260866 AB - Exposure to bis-(2-chloroethyl)sulfide (BCES; "sulfur mustard") causes delayed formation of slowly healing skin blisters. Although the histopathology of BCES injury is well characterized [reviewed in Smith et al., J Am Acad Dermatol 32: 767-776, 1995], little is known of the cutaneous toxicity at the molecular level. To identify biological markers of exposure, epidermal and subepidermal extracts were prepared from 48 individual hairless guinea pigs (HGP) at successive 3-hr intervals following exposure to BCES vapor, and compared using gel electrophoresis, and lectin- and antisera-binding. Inflammation was assessed by measuring edema and myeloperoxidase activity. Edema reached peak levels at 15-18 hr and remained elevated above controls at 24 hr. Recruitment of neutrophils, deduced from increased myeloperoxidase, occurred as early as 3 hr after BCES exposure with maximum infiltration at 6-12 hr. Binding of concanavalin-A lectin revealed increased amounts, relative to contralateral control sites, of two approximately 180,000 Mr polypeptides in subepidermal protein extracts from the BCES-exposed skin obtained > or = 12 hr after exposure. This alteration was not found in epidermal protein extracts prepared from the same animals. Based upon the determined amino acid compositions, both polypeptides had significant collagenous triple helical content (>75%). They could be distinguished immunologically from collagen types I, III, and IV by using polyclonal antisera. We conclude that exposure of HGP skin to BCES results in an early neutrophil infiltration that precedes epidermal-dermal separation and selective alterations of the subepidermal extracellular matrix.

AN - 79014938; 9153417 AB - O6-Methylguanine-DNA methyltransferase (MGMT), a ubiquitous DNA repair protein, acts as a monomer in removing the mutagenic DNA adduct O6-alkylguanine (induced by alkylating carcinogens) via a stoichiometric reaction. The alkyl group is transferred without a cofactor to a specific cysteine acceptor residue of MGMT, Cys-145 in the case of human MGMT, containing 207 amino acid residues and thereby inactivates the protein. As a prelude to the investigation of the reaction mechanism of human MGMT by elucidation of its structure in free and substrate-bound forms via NMR spectroscopy and X-ray crystallography, two types of MGMT mutants were generated and characterized. First, systematic deletion analysis of the protein was carried out to determine the smallest size at which it is active or inactive but forms a stable complex with the substrate and so may be useful for NMR spetroscopic analysis. Deletion of more than 8 or 31 residues from the amino or carboxyl terminus, respectively, led to the loss of both activity and substrate binding. Removal of Arg-9 or Leu-176 and distal residues inactivated the protein, presumably by altering its tertiary structure. On the basis of the criteria of bacterial overexpression and solubility, the mutant MGMT with deletion of 28 residues at the carboxyl terminus should be suitable for NMR studies. In the second approach, we examined mutants at the active site (Cys-145) that retain substrate binding. Inactive C145A and C145S substitution mutants were found to form specific and stable complexes with an O6-methylguanine (m6G)-containing oligonucleotide substrate. Wild type MGMT also formed a similar complex, but only as a transient intermediate. Footprinting studies indicated a strong discriminatory effect of the base adduct on the binding of C145A to substrate DNA; 17-18 nucleotides on the m6G-containing strand and 13-14 nucleotides in the complementary strand spanning the base adduct were protected from DNase I digestion by the mutant protein. These results, as well as the identical protease sensitivity of the wild type and mutant proteins, suggest minimal structural change due to conservative mutations at the active site. Thus, the mutant proteins may be utilized for solving the structure and mechanism of human MGMT.

The Military Medical Consortium for the Advancement of Retroviral Research (MMCARR). AN - 79502584; 9425690 AB - Drug reactions are common in HIV-1 disease, with the incidence having been reported to increase with increasing stage and with CD4+ T-cell counts below 200/microliters. However, there have been numerous reports of patients in which rechallenge, dosing changes or continued therapy have resulted in no recurrence or else clearing of the eruption. We followed 974 HIV-1-positive patients for 46 months as a part of a military study of HIV-1 disease. Within this group there were a total of 283 drug eruptions, with cutaneous manifestations in 201 patients in which clinical characteristics were noted and 86 patients in which cutaneous biopsies were performed. Serological evidence of reactivation or acute Epstein-Barr virus (EBV) or cytomegalovirus (CMV) infections were also noted, as well as peripheral eosinophilia. The incidence of drug eruptions significantly increased with increasing Walter Reed stage and decreasing CD4 counts and CD4/CD8 ratio, as well as with increasing age and in patients with increased numbers of other dermatological diagnoses. In addition, white patients had significantly more drug eruptions than did black. Serological or culture evidence of acute or reactivated EBV or CMV was significantly increased in patients with drug eruptions. The majority of the eruptions were maculopapular or morbilliform with a predominantly perivascular mononuclear cell infiltrate. HIV-1 positive patients have an increased incidence of drug reactions, the incidence having been reported to increase in patients with less than 200 CD4+ T cells/microliter. However, at very low T4 counts, especially those less than 25/microliter, and at a CD4/CD8 ratio of less than 0.10, the probability of reactions to trimethoprim-sulphamethoxazole (TMP-SMZ) is decreased in late-stage HIV-1 patients. Maculopapular or morbilliform eruptions are the most common clinical presentations, often accompanied by one or more of the following: fever, arthralgias, eosinophilia, and serum transaminase elevation. Histologically the majority of these eruptions show a perivascular mononuclear cell infiltrate, sometimes with focal interface changes and apoptotic, necrotic cells within the epidermis. Acute hypersensitivity reactions and toxic epidermal necrolysis (TEN) or Stevens-Johnson's syndrome (SJS) with diffuse epidermal apoptosis and necrosis have also been less commonly described. In a study of cutaneous manifestations in an HIV-1 positive military population, drug reactions were evaluated in terms of clinical features, histopathology, demographic features and laboratory findings.

AN - 79085443; 9203298 AB - On 24 February 1995, six U.S. soldiers serving with the Multinational Force in Haiti became ill after eating a locally caught fish identified as the greater amberjack Seriola dumerili. The victims presented with nausea, vomiting, watery diarrhea and abdominal cramps 5-8 hr after consumption. Also present in some victims were numbness in the extremities or perioral region, bradycardia and scalp paresthesia. Patients were treated with i.v. hydration therapy and antiemetics. All recovered without sequelae over the course of 1-3 months. A portion of the cooked fish was obtained for analysis. A semipurified lipid extract was prepared according to standard methods and analyzed for the presence of Na+ channel site 5 binding activity using a brevetoxin receptor binding assay. By this assay, the fish sample contained the equivalent of approximately 20 ng Caribbean ciguatoxin/g flesh. The presence of the major Caribbean ciguatoxin (C-CTX-1) was confirmed by liquid chromatography-mass spectrometry. Using the receptor binding assay to monitor activity in TSK and PRP-1 column fractions, two minor toxins were detected in addition to C-CTX-1. One of these minor toxins was more polar, and the other less polar, than C-CTX-1. These data provide firm evidence that a family of C-CTX-1 is responsible for ciguatera in the Caribbean.

AN - 79004393; 9144634 AB - Although the exact pathogenesis of mustard gas-induced dermal toxicity remains elusive, morphopathological data gathered in controlled animal and in vitro investigations is providing important clues as to approximate mechanisms. Our laboratory has been studying dermal effects of the chemical warfare agent, sulfur mustard, in a variety of animal models, cultured isolated human cells, and in vitro organotypic skin models. Published anatomical, pathological, and ultrastructural results of these studies have documented consistent cellular and basement membrane zone effects irrespective of the model. Cellular effects include the early targeting of basal cells of the stratum basale to the exclusion of other epidermal cells, with nuclear and cytoplasmic indications of cell injury and cell death. Effects on the basement membrane zone include the formation of characteristic microvesicles in the lamina lucida of those models which possessed structural components of a true basement membrane.

AN - 78971556; 9115017 AB - The case-crossover design is a new method for studying acute effects of transient exposures, in which cases serve as their own controls. To assess the validity, strengths, and weaknesses of the design, we used both the case-crossover method and the traditional case-control method of multivariate analysis with data collected from 196 cases and 295 hospital controls to study risk factors for hemorrhagic fever with renal syndrome in Korean soldiers. Both case-control and case-crossover methods showed that living in primitive field conditions, exposure to dust, and exposure to rodents were risk factors; use of insecticides or insect repellents was protective. Odds ratios from the case-crossover method were generally somewhat higher for risk factors and lower for protective factors. The case-crossover technique has great potential as a powerful, cost-effective way to assess risk factors for conditions such as infectious diseases and injuries, while avoiding some of the bias and logistical problems of traditional study designs.

Today's landfills, when built to regulatory standards, are unlikely to be critical, but older landfills can be seriously hazardous. Consequently, the hazards are graded as: (1) none to negligible; (2) low; (3) moderate; and (4) great. For non-critical sites, motions may be obtained from a probabilistic map but a deterministic map, if available, is preferred as part of a non-site-specific investigation; however, for critical sites, a deterministic, site-specific evaluation should be made. Motions must be specified appropriately for the type of analysis, whether it is for foundation liquefaction, stability of slopes, integrity of barriers, earth pressures, or the design of appurtenant structures.

These changes will not affect the Corps responsibility for providing safe and reliable channels and harbors for the nation's commercial vessels. The legislation will, however, require the Corps to make business process adjustments. Congressional action in the appropriations legislation decreased the amount of dredging normally performed by Corps hopper dredges by 8.5 million cubic yards-a boost of a million cubic yards over last year. In addition, the appropriations act allows only normal maintenance and repair to be performed to the Corps' 30-year-old, 3,140-cubic-yard hopper dredge McFarland.

In the presence of 12 mg of initial fungal inoculum, GTN (48.5 to 61.6 mu mol) was quantitatively transformed in a stepwise process to glyceryl dinitrate (GDN) and glyceryl mononitrate (GMN) within 48 h followed by a decrease in the GDN content with a concomitant increase in the GMN level. GDN was totally transformed to GMN within 168 h, and the complete degradation of GMN was achieved within 336 h. The presence of glucose and ammonium nitrate in the growth medium was essential for completion of the degradation of GTN and its metabolites. Complete degradation of GTN by a fungal culture has not been previously reported in the literature.

Reference samples were a mature green-colored corn leaf, green-, yellow- and brown-colored soybean leaves, cellulose, commercial grade cotton batting, and a soil. Spectral lummescence signatures were collected over the 300 to 800 nanometer region using a scanning spectrofluorometer. The excitation-emission spectra were broadband emission centroids in the 400-nm to 600-nm spectrum. Emission maxima were associated with the 440-nm, 470-nm and 370-nm excitation bands and the 455-nm to 590-nm emission bands. The coma of milkweed, silkvine, cotton (raw), cottonwood seeds and yellow-colored pollen and spores were higly fluorescent. The pappus of thistles, dandelion and goat's beard seeds and newly senesced grass leaves and glumes had moderate to high fluorescence. Dark brown-colored mushroom spores and weathered, senesced plant materials had low fluorescence. The emission spectra resembled that of reagent, microcrystalline cellulose although impurities incorporated within the plant materials altered their emission intensities from that of cellulose. Moderate to low emissions were from tan- to dark brown-colored materials, whereas the white-colored or light, tan-colored materials had high emissions.

AN - 79083340; 9193342 AB - To assess the efficacy and toxicity of suramin, hydrocortisone, leuprolide, and flutamide in previously untreated metastatic prostate cancer. Patients with stage D2 and poor-prognosis stage D1 prostate cancer were given suramin on a pharmacokinetically derived dosing schedule to maintain suramin concentrations between 175 and 300 micrograms/mL. Additionally, all patients received flutamide 250 mg orally three times daily, initiated on day 1 and continued until disease progression; depot leuprolide 7.5 mg intramuscularly begun on day 5 and repeated every 4 weeks indefinitely; and replacement doses of hydrocortisone. Fifty patients were entered onto the study: 48 with stage D2 and two with stage D1 disease. The median age was 59 years (range, 42 to 79) and 31 patients had a Karnofsky performance status (KPS) of 100%. Forty-five patients had bone metastases and 25 had measurable soft tissue disease. Forty-one (82%) had severe disease. The overall response rate in 49 assessable patients was three complete responses (CRs) and 30 partial responses (PRs) for an overall response rate of 67%. Eighteen patients have died. The median survival time has not been reached, with a median potential follow-up duration of 44 months. Grade 3 to 4 toxicity was seen in 38% of patients and was predominantly hematologic and reversible. The high response rate and prolonged survival in a poor-prognosis group of patients with metastatic prostate cancer warrant a phase III randomized comparison of this regimen versus hormonal therapy alone. Toxicity was moderate and reversible.

In this bench-top study, the authors examined the effectiveness of a frozen-ground barrier in containing heavy-metal-laden liquid generated during soil remediation. A soil, artificially contaminated with Cd, Cu, Ni, and Zn, was placed above a frozen water-saturated uncontaminated soil layer. The temperature of the frozen layer was maintained at -3 degrees C. The contaminated soil was flushed with a 0.1 M EDTA solution. Over 90% of the Cu and Zn and over 80% of the Cd and Ni were recovered from the unfrozen layer. Most of the remaining metals were found in a narrow zone of soil at the boundary between the frozen and unfrozen layers, while smaller amounts appear to have migrated into the barrier, apparently by diffusion in liquid-water films. The experiments demonstrated that the frozen-soil barrier prevented the migration of most of the metal-EDTA complexes, even at only -3 degrees C. While the mechanism for the movement of small amounts of metals into this layer remains unclear, the authors suspect cooling below -3 degrees C would improve the barrier's performance.

Their observations about frost penetration, snow cover, soil moisture content, and related factors are useful in monitoring the conditions of hay and pasture, as well as fall planted small grains. Knowledge of frost depth also permits more accurate predictions of the spring runoff from snowmelt and beginning of spring field work. Contractors, commercial industries, insurance companies, utilities with underground facilities such as water and gas lines, and winter sports facilities also have need for this information. The collection of this data is a joint project between the College of Agricultural and Life Sciences of the University of Wisconsin, the University of Wisconsin Extension, the Wisconsin Agricultural Statistics Service and the National Weather Service.

The spatial distribution of site-specific factors including residue biomass, soil bulk density, and total water content was measured within the catchment, and the spatial distribution of topographic indices were calculated for the catchment using the TAPES-G model. These topographic indices and site specific factors were correlated with measured frost depth and date of complete soil thaw. Regression equations were derived to predict maximum frost depth and date of complete thaw. Results point out the effectiveness of topographic indices to quantify the spatial distribution of frost depth. JF - Special Report - Corps of Engineers, U. S.

The authors' goal was to unravel the little knowledge of organic matter of ornithogenic soils by means of wet-chemistry and nuclear magnetic resonance spectroscopy (NMR). In contrast to the German soils the SOM of the antarctic soils was characterized by a high percentage of amino derivatives from proteins, polysaccharides, urates and chitin, resulting in a mean C-to-N ratio of 10. The high content of carboxyl carbon units probably derived from amino and other organic acids. The pattern of the (super 1) 5N-NMR spectra of the penguin guano suggested the presence of uric acid. Concerning the podzolization process the data suggested the migration of organic acids, not-humified carbohydrates an N-containing moieties, from the topsoil into the spodic horizons of the ornithogenic soils. In the SOM of Podzols formed under temperate climate conditions N-compounds, and non-humified carbohydrates were of minor importance within the SOM translocation processes. (Auth.)

Swedish experiments suggest that subsoil compaction can persist over 11 years despite annual freezing below the depth of compaction. There is also evidence that, in proximity to the soil surface, a decline in soil density and penetration resistance occurs overwinter in the northern United States in response to natural forces such as freezing and thawing. A paucity of information exists, however, on the persistence of compaction beyond a decade. Wagon wheel ruts are evident along some pioneer trails that traversed the continental United States in the late 1800's, suggesting that compaction can persist for over a century. One such trail, the Wadsworth Trail that traversed western Minnesota from 1864 to 1871, was the focus of this investigation where we examined soil physical properties across a portion of the trail. Physical properties assessed were soil water content, thermal conductivity, penetration resistance, water infiltration, and air permeability. Soil density appeared to be greater within the area occupied by the wheel ruts, compared to that outside the wheel track, as suggested by the higher penetration resistance and lower water and air infiltration. Indeed, complete amelioration of physical properties that characterize compacted soils was not evident after at least 85 years. This information suggests that for a sustainable and productive ecosystem, compaction of soils should be minimized by either using confined wheel traffic patterns or curtailing traffic on wet soils.

Stationary installations were devised to test the efficiency of micrologging techniques for measuring apparent electrical resistivity, spontaneous and electrode potentials, and electrode resistance using various measurement modes. This yielded interesting practical results and methodological findings with regard to non-conventional ways of study the active layer dynamics and of the phase interface position spatial and temporal variability.

This method was used for determination of crystallization heat of water in clays. The results obtained show that crystallization heat of soil water at low moisture is much different from that of volume water. The calorimetric tests in determining unfrozen water show that an effect of the difference is much evident. For example in clay samples examined the amount of unfrozen water is 20-30% less at -10 degrees C using the values of crystallization heat of soil water, compared with the ones for volume water.

It includes three independent analytical models: FRED (FREezing Depth), which simulates variations of soil freezing depth, SOT (SOil Temperature), calculating the vertical profile of soil temperature before the spring snow melt, and MIR (Melting, Infiltration, Runoff), simulating the spring snowmelt with subsequent infiltration and surface runoff. COLD was validated for the forest-steppe zone of Russia using agrometeorological data from 1955 to 1988. After that, COLD was incorporated into a package ANDY_SWASH (ANnual DYnamics of Soil WAter Stores for Homogeneous areas), which was also validated using the above-mentioned data. Verification of simulated water storage in the 1-m soil layer against observations in various non-forested ecosystems shows good agreement. JF - Special Report - Corps of Engineers, U. S.

Cumulative infiltration for two cases of cycling of temperature are compared with estimates predicted by a parametric correlation. The correlation is based on infiltration into a frozen soil with a constant, continuous supply of water at the surface during quasi steady state flow. It requires information on surface saturation, initial soil saturation, initial soil temperature, saturated hydraulic conductivity and infiltration opportunity time. The comparisons demonstrate that the amounts of infiltration under cycling of temperature usually are less than those predicted by the correlation. However, the differences are relatively small (usually <10%). Comparisons of seasonal snowmelt infiltration by a modified correlation that accounts for the effects of cycling show reasonable agreement with field estimates determined from measurements of soil water changes.

The technique is particularly well-suited to use in the Arctic, where in situ and potentially remote methods are important. The objective of this study is to evaluate TDR as a field technique for bulk electrical conductivity sigma (sub b) and soil water electrical conductivity sigma (sub w) in arctic soils. Calibration measurements of sigma (sub b) were carried out at a field site in Siberia (74 degrees 32'14"N; 98 degrees 35'52"E). TDR-determined sigma (sub w) using the model of van Loon et al. (1991) is compared to electrical conductivity sigma (sub w) of solution obtained with suction cups. Best results are obtained when using a probe specific calculated soil electrical conductivity sigma (sub s) , rather than one value for this soil type. This is thought to be a reflection of soil coarseness and heterogeneity. Data of sigma (sub w) obtained for this field site are reported for one field site in Siberia from spring to fall 1995. Infiltration into the frozen soil in spring and exclusion of solutes during fall freeze-back were observed using TDR. JF - Special Report - Corps of Engineers, U. S.

Soil thermal and hydraulic conditions during thaw consolidation are regarded as crucial for understanding gelifluction processes. We set up a field station in the periglacial altitudinal belt of the Austrian Alps, 2650 m a.s.l., to investigate the dependency of solifluction movements on the ground thermal and hydraulic regimes. Automatic measurement devices included solifluction meters for the observation of subsurface soil displacement, heave meters, as well as TDR, tensiometers and thermistors. Preliminary results demonstrate that ground freezing and frost heave continued throughout the winter. Additional ground ice accumulated during early snowmelt events. The onset of strong gelifluction in response to ground thaw was recorded at a high temporal resolution. The importance of climatic control on solifluction was supported by the results of annual surface marker observations. JF - Special Report - Corps of Engineers, U. S.

Agronomists have tended to emphasise chemical/physical interpretations. The microclimatological questions are also analysed in diverse ways. An historical review provides the background for an integrated study of the effects of freezing in relation to the soil microstructure. The thermal properties, strength and deformation, transport phenomena, hydrologic and other characteristics of frozen ground are determined by the thermodynamic relations of the unfrozen water and ice. These relations are a consequence of the soil's porous nature and of the form and extent of particle surfaces. The microscopic structure of a freezing fine-grained soil is the origin of its particular bulk properties. This is the basis of research into more cost effective responses to the contamination of ground in cold regions and other current issues. JF - Special Report - Corps of Engineers, U. S.

Current literature does not discuss the mechanisms causing these high loss rates. The objectives of this paper are to 1) propose soil hydraulic and mechanical processes and conditions which occur on a soil interrill surface during rainfall; 2) suggest impacts of a subsurface frozen layer on these processes and conditions; and 3) identify frozen-layer effects on soil detachment from raindrop impact. A frozen layer beneath the surface restricts infiltration, causing water to accumulate above the impermeable layer. It is hypothesized that restricted infiltration, high matric potential, and low soil shear-strength stop surface seal formation, greatly increase detachment from impacting rainfall, and greatly increase soil erodibility. Research indicates that as matric potential nears 0 Pa, soil detachment from raindrop impact is four times greater than can be explained by shear-strength estimates in the detachment zone. These high matric potentials add considerably to the erosion potential of soils with thawed surfaces and frozen subsurface layers. JF - Special Report - Corps of Engineers, U. S.

Experiments were conducted to measure the effects of free/e/thaw on soil water and solute movement in a Webster silt clay loam (fine-loamy, mixed mesic Typic Haplaqualls). PVC cylinders (0.13 m inside diameter and 1.2 m long) were packed with topsoil. Potassium bromide tracer was placed in the top 0.05 to 0 15 m soil layers in some of the columns. The soil columns were buried vertically in the field and exposed to the winter freeze/thaw conditions. Field columns were extracted throughout the winter and sectioned into 0.05 m layers. Each layer was analyzed for water content, bulk density, and electrical conductivity. Water moved upwards to the freezing zone carrying along some solutes. Electrical conductivity values verified the movement of solutes during the freeze/thaw periods. Bulk density changed abruptly due to expansion and compression of the soil matrix during freeze/thaw periods. Physical properties of thawed soil retained some of the changes caused by freezing and remained more variable compared to the properties of unfrozen soil. JF - Special Report - Corps of Engineers, U.

We analyse the Miller model of frost heave for such spatial instability, by incorporating three-dimensionsal heat and mass transfer, and allowing the frozen soil to deform as a viscous medium. We find that the heaving process is generally (but not always) stable, but that if account is taken of a surface snow cover, then the insulating thermal properties of the snow predict that instability will occur if a dimensionless parameter N>0.02. The parameter N is given by N = n (sub f) v (sub s) /(rho (sub f) gd (super 2) ), where n (sub f) is the frozen soil viscosity, v (sub s) is the surface heave rate, p (sub f) is the frozen soil density, g is gravity, and d is the depth of the freezing front. This implies that the propensity for differential frost heave depends on the soil heaving characteristics, as well as the rate of frost penetration. JF - Special Report - Corps of Engineers, U. S.

My objectives are to determine the effects of freeze-thaw (FT) on vehicular ruts, which concentrate flows and often erode to gullies. A noncohesive silt was rutted with a pickup truck, then frozen and thawed three times. Frost heave, rut geometry, soil compression, shear strength, and infiltration were measured. Results show that 1) ruts start to freeze later and thaw slower than uncompacted soil; 2) once ruts start to freeze, they freeze faster than unrutted soil; 3) the ruts heave an average of 0.2 to 3.2 mm more than unrutted soil; 4) the infiltration in ruts increases by 62%, unconfined compression strength decreases by 16% and shear strength by 14%, and rut hydraulic radius decreases an average of 9% after three FT cycles. These results suggest that the volume of water flowing in these ruts would be lower, the rut soils would be weaker (more erodible) and the rut flow velocity would be lower after the FT cycles. Future experiments will investigate rut and rill responses in different soils at variable FT rates. JF - Special Report - Corps of Engineers, U. S.

We have made a broad range of measurements during the snowmelt season for several years at the University of Minnesota Agricultural Experiment Station in Rosemount, MN. In level portions of untilled fields the contribution of snowmelt to soil moisture recharge is generally small (less than 20% of overwinter liquid equivalent precipitation). Evaporation is also not a large sink for water from the snowpack; model estimates suggest it accounts for less than 20% of the overwinter precipitation. Most of the water released during snowmelt finds its way to low points within the field, resulting in the formation of large ephemeral ponds, which can form within a day to depths approaching 1 m. Infiltration is often almost as rapid, despite the presence of a frozen layer in the soil below. JF - Special Report - Corps of Engineers, U. S.

X-ray diffraction, elemental analysis, micromorphology, chemical treatment, and freezing experiments were used to deduce the petrogenesis of these particles. The particles are yellowish-red, platy to tabular, and composed of accreted crystalline domains. Based on optical properties, they appear to have weathered from biotite; however, the lithology of the surrounding rock types refutes this suspicion. In soil thin sections, they occur in root channels and voids as oriented masses with visible accretionary laminae. Particles similar in form and optical properties to the soil minerals were synthesized by repeated freezing and thawing of high iron kaolinite extracted from the soils. Synthesis of the data supports the conclusion that these soil particles formed via accretionary freeze-thaw-aided growth from colloids. The large proportion of the freeze aggregates in the sand-sized fraction of these soils suggests they are important for physical stability and infiltration. Argillans in soils subjected to frequent freeze-thaw cycles may be formed by freeze accretion of colloids and not illuviation. JF - Special Report - Corps of Engineers, U. S.

Monitoring sites are located within successional forest stands resulting from silt-bar deposition in five successional stages. In this paper we show differences in soil temperature and seasonal rate and depth of thaw that have developed as a result of the successional change in the vegetation. Year-to-year variability in environmental parameters is also shown to have an effect on the soil microclimate. Important factors in determining the soil temperature profile and rate of thaw are organic layer thickness, canopy cover, and snow depth. JF - Special Report - Corps of Engineers, U. S.

The stations have been operating for up to a five-year period, and data from each location from 1992-1995 was utilized. Elevation had a much greater impact than latitude or longitude on soil temperature and freezing and snowfall parameters within the state of Colorado. Regression of soil temperature with air temperature was significant at each location; however, the regression equations varied from site to site. The first fall frost was more strongly correlated with both the length of the frost-free period and the number of thaws (in both spring and fall) than was the last spring frost. The first fall frost is an important variable because, if it arrives early, yield quality can be damaged. The number of thaw cycles was greater in the spring than in the fall at all elevations. The freezing and thawing action in the spring can have a significant effect on crop stand establishment and winter hardiness of perennials. JF - Special Report - Corps of Engineers, U. S.

The Pitzer equations are statements of a solution's excess Gibbs energy. When fully parameterized, the Pitzer equations allow the calculation of activity coefficients, osmotic coefficients, enthalpies, entropies, Gibbs energies, heat capacities, and molal volumes of highly concentrated aqueous electrolyte solutions to temperatures below -50 degrees C. While developed to calculate capillary pressures for pure pore liquids, the theoretical development that yielded thermoporometry can be extended directly to pore solutions composed of complex electrolyte solutions, by which freezing behavior of chemically realistic natural soils can be calculated. Application of the FREZCHEM model to an arctic permafrost soil demonstrated that significant amounts of water may remain liquid in saline soils as the result of salt exclusion from ice during the freezing process and the formation of brine pockets. These simulations also demonstrated that environmental conditions are marginally suitable for microbial activity in frozen soils under extreme conditions. Frozen soils have the potential to serve as a refugium for life. JF - Special Report - Corps of Engineers, U. S.

Hydrology in discontinuous permafrost is extremely complicated and many obstacles were encountered in attempts to model transport plumes. In this area, the presence of ancient sloughs, discontinuous permafrost, low hydraulic gradients and the rise and fall of the Chena River that flowed adjacent to the area studied make this system very complex. The process of infiltration of surface water to the groundwater represents a major unknown, not just in regard to magnitude, but also in terms of spatial distribution of recharge. An understanding of the temporal dynamics of groundwater recharge was obtained through measurements of precipitation input (rainfall and snowmelt) and the response of soil moisture and groundwater levels. The results of this study indicate that summer precipitation amounts just meet evaporative demands and do not allow for significant groundwater recharge. JF - Special Report - Corps of Engineers, U.

The objectives of this laboratory experiment were to quantify aggregate stability of relatively wet aggregates from the Ap horizons of four soils when subjected to either 0, 1, 2, or 4 FTCs and, secondly, to identify a threshold number of FTCs for each soil below which aggregate stability increases. Moist soil was packed into 28-mm-diam., 50-mm-tall brass cylinders by tapping to a dry bulk density of 1.15 Mg m (super -3) , sealed in polyethylene bags, then slowly frozen convectively at -5 degrees C for 48 h, then thawed at +6 degrees C for 48 h for each FTC. The first 1 to 2 FTCs in general increased aggregate stability, but additional FTCs had little effect. For 3 of 4 soils, 2 to 3 FTCs appeared to increase aggregate stability to a plateau or threshold. FTCs increased aggregate stability, when averaged across the four soils, more in the 0- to 15-mm depth increment than in the 15- to 30-mm increment. JF - Special Report - Corps of Engineers, U. S.

Hourly temperature time series from thermistors at eight levels in the near-surface soil were available from three sites in Alaska. Using 3-hr averages, the simulated temperature was subtracted from the observed temperature for each level. These residuals indicate the relative magnitude and time-dependence of nonconductive heat transport. The temporal pattern of residuals suggests that the thermal field in midwinter most closely fits the conductive model. Negative residuals early in summer appear to result from the combined effects of evaporative cooling and upward migration of cooler water. These processes reduce the mean annual ground temperature by about 1 degrees C in the middle region of the active layer. Conversely, residuals are positive during the zero-curtain and the snowmelt periods. JF - Special Report - Corps of Engineers, U. S.

Computer optimization of the default data of minerals' occurrence in soils has improved predictions by about 14%. The computer package developed (TheHyProS) is based on modified existing predictive models (De Vries, Campbell, etc.) and allows quick estimation of thermal conductivity, specific heat, and hydraulic properties over a full range of moisture content and over a temperature range of -30 degrees to 95 degrees C. A user-friendly interface allows for either default or self-entered modes of input. The default mode allows a soil selection from 12 available USDA textural classes. Reasonable assumptions concerning soil composition and compaction are made allowing use of the program by users with little soil physics knowledge. The self-entered mode requires data concerning bulk density, porosity, mineralogical composition and thermal properties of mineralogical components, grain size characteristics, and mass fractions of sand, clay and silt. Estimation of field conditions (i.e., expected soil moisture range, thermal conductivities, and specific heats under normal field conditions in a moderate climate) is also provided. Graphs and data may be viewed from within the program, or exported to many word processors or graphing packages. JF - Special Report - Corps of Engineers, U. S.

In this paper we analyzed field runoff data collected at scales ranging from 1-m (super 2) to 13 ha with the intent of identifying practical scales for modeling frozen soil runoff. We found that: (i) there is extremely high spatial variability of runoff at the 1 m (super 2) scale which is probably due to the highly variable snow distribution affected by vegetation, (ii) this variability is effectively "averaged out" at the scale of 30-m (super 2) plots, and (iii) an increase in scale introduces a new source of variability, topography, which must be accounted for. It may be that at larger scales topographic effects are also "averaged out." JF - Special Report - Corps of Engineers, U. S.

We found that the slope of the resistance vs. time curve changed distinctly at the depth of the 0 degrees C isotherm, and the change accurately indicated the depth of frost.

The complex interactions between heat and water flows, as well as different scales, make it difficult to quantify field conditions. In the present study four small soil plots were investigated with regard to the water and heat dynamics during one winter season (1995/96). Profile measurements of soil temperature, liquid and total water content were used to test a one-dimensional deterministic model (SOIL). The model calculates the water flow in a frozen soil in two domains. The general agreement between the measurements and the simulated results was satisfactory, mainly with respect to the water budget in the topsoil during the three snowmelt events of the winter.

In 1988 and 1989, hydrochemical sampling was performed in the Apsat River basin located in the Kodar-Udocan District. The variation of pH values, of ionic strength of solution, and of Kurlov's formula are reported. The secondary mineral stability fields were found from Helgeson's diagrams. In 1988 the secondary products of weathering rocks were leonhardite, gibbsite and kaolinite. In 1989 the secondary minerals were mainly leonhardite and gibbsite, and on some samples of water, the secondary mineral kaolinite was noted. In 1988 certain samples of waters were saturated by quartz. Waters of 1989 were not saturated by quartz. Free and aggressive carbon dioxide quantities, stability on saturation indexes for calcium carbonate were determined. JF - Special Report - Corps of Engineers, U. S.

A test cavity was excavated, and at the conclusion of the experiment the diesel was not removed, but sawdust was added to adsorb the diesel, and the shaft leading from the cavity to the surface was backfilled with gravel. In 1994, diesel fuel was observed on the soil surface in the vicinity of the shaft. The entire gravel shaft was contaminated with diesel; the soil outside the shaft exhibited much lower levels of contamination. A video camera lowered into the cavity showed massive ice on all cavity walls. The authors tentatively conclude that during the years 1975-1994 water entered the gravel shaft, migrated downward to the cavity, and displaced the diesel fuel which moved upward through the shaft. The permafrost cavity failed to provide an environmentally sound enclosure for the diesel. JF - Special Report - Corps of Engineers, U. S.

An integrated approach, including wet-chemical analyses, cross-polarization magic angle spinning carbon-13 nuclear magnetic resonance spectroscopy (CP/MAS (super 1) 3C-NMR), and pyrolysis-field ionization mass spectrometry (Py-FIMS), was applied to characterize the soil organic matter (SOM) composition at different depths. Dead moss was the fresh organic matter. Aliphat-C units dominate in the SOM. Alkyl compounds consist of lipids, fatty acids and sterols. The aromatic structures identified by CP/MAS (super 1) 3C-NMR and by Py-FIMS demonstrate that lignin input is not necessary for the formation of aromatic humic structures. Within the humification process, carbohydrates are less mineralized in Antarctica than under temperate climate conditions and these moieties also dominate in the SOM of deeper horizons. The extremely cold climate conditions of Antarctica retard the transformation of fresh organic residues. Nevertheless, alkyl carbon units are incorporated into the complex humic matter and enriched due to a selective preservation. (Auth.) JF - Special Report - Corps of Engineers, U. S.

Although numerous attempts are being made to clean up contaminated soils with the use of in-situ and non-in-situ techniques, none of these is a panacea because of the complexity of soils and the presence of multiple contaminants. As one of in-situ cleanup methods, the combination of artificial ground freezing and electroosmosis techniques might be useful to decontaminate polluted soils. In the present study, movement of water and sodium ions has been measured in frozen clay at subzero temperatures under an electrical gradient (3 V/cm) for 24 hours. Then the experimental results have been simulated by a simple model based on a convective diffusion equation. JF - Special Report - Corps of Engineers, U. S.

The cool period is characterized by much snow accumulation and frequent snowmelts. To examine accurately the extent of soil movement over affected fields, a system of actual field measurements of rills and sediment deposition zones was devised and applied in early spring to a number of field sites in potato rotation with cereal grain or forages (for hay) as intervening crops. Cool-period erosion from untilled grain/forage land averaged 0.1 t/ha compared to 8 t/ha from tilled grain/forage fields. After potato cropping, overall soil loss increased to 20.3 t/ha with tillage and 19.8 t/ha without tillage. Between 33% and 80% of the sediment stayed in the fields; however, sediment deposition affected only small areas of these fields, <1%-3%. JF - Special Report - Corps of Engineers, U. S.

Granular potassium chloride (KCl) was surface applied to two areas overlying subsurface drains and to one area instrumented with soil solution samplers and ground water monitoring wells. One of the subsurface drain tracer plots was located on level ground while the other two sites were in small topographic depressions. The applied tracer was found to move rapidly to the shallow ground water under the depressional areas after infiltration of spring snowmelt in 1994. Excessive rainfall events were also responsible for the rapid transport of the applied chloride tracer. The findings of this study indicate that, under certain conditions, it may be necessary to delineate areas of a field based on topography to be integrated into a site-specific farming plan.

Fast freezing of soil aggregates at high water contents results in a reduction in wet aggregate stability, and an increase in the generation of dispersible clay. Incubation at temperatures above freezing, following a frozen period, reduces the effects of freezing. Greater deterioration was noted as a result of the treatments involving two temperature cycles as compared to just one. Soil pH appears to play a role in determining the stability of soil aggregates during freezing conditions, although the effects are confounded with those of the organic matter content of the soil.

Soil aggregates can fracture by the combination of freezing and thawing and freeze drying, making the resultant soil fragments more susceptible to wind erosion. A study was conducted over the winters of 1989-90 and 1990-91 near Morris, Minnesota, on a Barnes-Aastad loam association to determine changes in aggregate size, as affected by tillage and crop rotations. Aggregate size distribution was determined by dry sieving in the fall after tillage and again in the spring before tillage. Overwinter processes influenced aggregate size, with the magnitude and direction of change influenced by soil water during the winter season. In the first year of this study, when the soil was moist prior to the first fall freeze but dried by sublimation during the winter, aggregates degraded to size fractions susceptible to wind erosion. In the second winter when snow melt recharged surface soil water, aggregate size increased from fall to spring on treatments with surface residue. JF - Special Report - Corps of Engineers, U. S.

The proposed model allows us to calculate the variation of the area-averaged soil freezing depth and its standard deviation for areas with intermediate linear size ranging from several tens of meters up to several tens of kilometres. This model was validated using standard records of the agrometeorological and water-balance stations located in the Kursk region (forest-steppe zone, Russia), and experimental studies carried out by the authors at the Kursk Biosphere Station.

It includes models for soil freezing, water migration to the freezing zone from the underlying unfrozen zone, soil temperature profiles before and during the spring snowmelt, water infiltration into frozen soil, soil thaw and its heating after snow-cover loss. The models were created on the basis of the integral balance method what allows one to combine the physical basis of models with simple mathematical formulations. The calculated dynamics of soil freezing depth, soil temperature and moisture profiles, the total amount of infiltrated water, and daily runoff were verified against the observations. The results of field investigations by the author and measurements of water-balance stations situated in the forest and forest-steppe zones of the European part of the Former Soviet Union were used to validate model simulations.

Slope processes such as active-layer detachments and retrogressive thaw slumps are characteristic of Central Yamal. They produce specific impact on chemical composition of the surface and underground (active layer) runoff. Removed matter as well as exposed surface are subjected to washing out of water-soluble salts and insoluble particles. Upper permafrost: ice-bonded deposits or massive ground are exposed to seasonal thaw and washed by surface and active-layer water. Depending on the ice type, different elements and ions get into the runoff and drainage system. The impact of water-soluble salt redistribution within the newly formed active layer on the active-layer runoff is considered as well. Peaks of concentration correlate with the peaks of active-layer detachment activity. JF - Special Report - Corps of Engineers, U. S.

The flow cross-section is rectangular, the flow width is uniform, the channel bed is flat; the plan shape is sine-generated. In contrast to previous works, where the computed flow patterns were of the same character, irrespective of the sinuosity of the channel, it is found, on the basis of present experiments, that every different plan geometry of a meandering flow has its own flow picture. In the case of "small" sinuosity, the flow convectively accelerates at the inner bank between the crossover- and apex-sections; if, however, the sinuosity is "large", the flow convectively decelerates in the same region. The convergence-divergence areas (in flow plan) of the present flows are in coincidence with the location of erosion-deposition zones in meandering streams, confirming that the convective behaviour of the vertically-averaged flow alone is sufficient to induce the bed and bank deformation.

Yet it is unclear whether the prospect of such change is relevant to water resources management decisions being made today. We model a shoreline protection decision problem with a stochastic dynamic program (SDP) to determine whether consideration of the possibility of climate change would alter the decision. Three questions are addressed with the SDP: (l) How important is climate change compared to other uncertainties?, (2) What is the economic loss if climate change uncertainty is ignored?, and (3) How does belief in climate change affect the timing of the decision? In the case study, sensitivity analysis shows that uncertainty in real discount rates has a stronger effect upon the decision than belief in climate change. Nevertheless, a strong belief in climate change makes the shoreline protection project less attractive and often alters the decision to build it. Copyright 1997 by the American Geophysical Union.

The rare isolation of a virulent F1- isolate from surviving animals supports earlier studies suggesting that improved vaccines should consist of immunogens to protect against F1- variants. The high degree of protection with IgG MAb suggests that secretory IgA is not required for protection from pneumonic plague.

In fiscal year 1996 (October 1995-September 1996), over $115,000,000 was expended on work associated with 19 Superfund sites, Army facilities at Fort Devens and the Materials Technology Laboratory (MTL) in Watertown, Mass., as well as numerous formally used defense sites throughout New England. Note-worthy projects include the Baird and McGuire Superfund site in Holbrook, Mass., where contaminated soil is being excavated and incinerated on-site, and the Raymark Superfund site in Stratford, Conn., where 13 acres of industrial buildings were demolished with the site now being capped. NED expects that over $100,000,000 will be expended in fiscal year 1997 as work continues at Baird and McGuire, Raymark, Fort Devens, and the Army's MTL. NED also expects to begin work on the Estuary, Lower Harbor/Bay portion of the New Bedford Harbor site this year. EPA announced their proposed plan for this portion of the site in November 1996. The protect will involve the dredging of approximately 344,000 m super(3) (450,000 cu yd) of contaminated sediment with disposal in shoreline facilities that will be constructed as part of the project.

Phospholipids are the main source of fatty acids in the bacterial cell and therefore should maintain the discriminating power of the fatty acid data. Under negative ionization conditions, phospholipids form predominantly deprotonated molecular ions. The principal bacterial phospholipids detected using negative ion ESI are phosphatidylglycerols (PGs). Chloroform:methanol extraction of whole bacterial cells resulted in ESI mass spectra. The product ion mass spectra of deprotonated PGs provided the molecular weights of the fatty acid moieties. The distribution of fatty acids for the different PG species, as well as the different profiles of PGs, allowed differentiation between the B. cereus group and B. subtilis and this could provide a chemotaxonomic method for bacterial differentiation.

AN - 78883592; 9079681 AB - Details of the interactions between the human immunodeficiency virus (HIV-1) reverse transcriptase and substrate DNA were probed both by introducing site-specific and stereospecific modifications into DNA and by altering the structure of potential critical residues in the polymerase. Unadducted 11-mer DNAs and 11-mer DNAs containing R and S enantiomers of styrene oxide at N2-guanine were ligated with two additional oligonucleotides to create 63-mers that served as templates for HIV-1 reverse transcriptase replication. Oligonucleotides that primed synthesis 5 bases 3' to the adducts could be extended up to 1 base 3' and opposite the lesion. However, when the positions of the 3'-OH of the priming oligonucleotides were placed 1, 2, 3, 4, 5, and 6 bases downstream of the styrene oxide guanine adducts, replication was initiated, only to be blocked after incorporating 4, 5, 6, and 7 bases beyond the lesion. The sites of this adduct-induced termination corresponded to the position of the DNA where alpha-helix H makes contact with the DNA minor groove, 3-5 bases upstream of the growing 3' end. In addition, mutants of the polymerase in alpha-helix H (W266A and G262A) alter the termination probabilities caused by these DNA adducts, suggesting that alpha-helix H is a sensitive monitor of modifications in the minor groove of newly synthesized template-primer DNA several bases distal to the 3'-OH.

Field measurements indicated uptake by benthic algae retained ammonium and phosphate in the sediments when light at the sediment surface exceeded approximately 150 mu E m super(2) s super(-1). The measurements were used to calibrate a newly developed model of benthic algal activity. The benthic algal model was coupled with a hydrodynamic model, a eutrophication model, and a sediment diagenesis model. In the simulated ecosystem, benthic algae had a major influence in the intra-annual cycling of nitrogen and phosphorus. When nutrients were abundant in the water column (late winter and spring) they were transferred to the sediments through algal activity. Diagenesis released these nutrients to the water column in summer when nutrients were scarce. As a result of the nutrient transfer, annual primary production in the water column, in the presence of benthic algae, exceeded production in the absence of the algae.

AN - 78880942; 9080598 AB - Various 4- and 8-aminoquinolines, which are effective antimalarial agents, were examined as potential pretreatment compounds for prolongation of the time to 50% block of nerve-elicited muscle twitches in isolated mouse diaphragms exposed to botulinum type A neurotoxin. The 4-aminoquinolines (chloroquine, amodiaquine) and quinacrine, an acridine derivative similar to chloroquine, prolonged the time required for botulinum type A neurotoxin to block neuromuscular transmission by more than 3-fold; 8-aminoquinolines (primaquine and WR242511) had no antibotulinum type A neurotoxin activity. Pyrimethamine, an antimalarial drug lacking the quinoline ring structure, was also ineffective. Rank order potencies based on equimolar effective concentrations for the test compounds were quinacrine > amodiaquine > chloroquine > quinine or quinidine. Maximum protection from botulinum type A neurotoxin-induced neuromuscular block was achieved when muscles were exposed to drug prior to or simultaneously with the toxin. A delay of more than 20 min abolished the protective ability of the antimalarial agents, presumably owing to the release of the toxin from endosomes in quantities sufficient to initiate neuromuscular block. All of the test compounds except quinine and quinidine depressed muscle contractions when concentrations exceeded 20 microM. In addition, amodiaquine at 50 microM induced muscle contracture. A combination of agents at low concentrations that act at different steps of botulinum type A neurotoxin poisoning potentiated the prolongation of time to 50% block in an approximately additive fashion. Thus N,N,N',N'-tetrakis(2-pyridylmethyl)ethylenediamine (2 microM) and quinacrine (5 microM), when administered in combination, produced up to a 4-fold increase in time to 50% block. A similar level of protection with quinacrine alone required a 4-fold increase in the aminoquinoline concentration. Although the mechanism of protection by these antimalarial agents is probably through the raising of endosomal pH, the possibility that some of these drugs could also act by inhibiting toxin-induced channel formation cannot be ruled out.

AN - 78873754; 9066107 AB - The genes encoding the CS6 colonization factor were cloned from two human enterotoxigenic Escherichia coli strains of different serotypes. The DNA sequences from both clones were nearly identical and contained four open reading frames. Two of them have homology to genes encoding molecular chaperones and ushers found in many other operons encoding colonization factors. The two remaining open reading frames encode two heterologous major subunit proteins which makes CS6 unique because other colonization factors have only one major subunit. Upstream and downstream of the CS6 operon the DNA sequences of the clones diverged abruptly.

AN - 78838156; 9056181 AB - A modified quantitative reverse transcriptase polymerase chain reaction (QRT-PCR) procedure was developed for measuring mRNA concentration, in rodent cells, of the N-methylpurine-DNA glycosylase (MPG), a ubiquitous DNA repair protein responsible for the removal of N-alkylpurines and ethenoadducts of adenine, guanine, and cytosine from DNA. The method, applicable for quantitation of any mRNA, is based on the standard approach of comparing the relative amounts of PCR products of the experimental mRNA and a known amount of an exogenous reference RNA which is nearly identical to the experimental RNA. However, unlike in the earlier procedures in which deletion or insertion sequences were added to the reference RNA template, which may affect the efficiency of PCR but are needed to generate different size PCR products, experimental and reference RNAs yield PCR products of the same size in the new method. However, prior digestion with EcoRI allows separation of the two products because a unique EcoRI site was created in the reference RNA vector by point mutations. The QRT-PCR procedure is particularly useful for studying expression of the MPG gene whose mRNA level is very low and difficult to quantitate by Northern blot analysis. The number of MPG mRNA molecules/cell in late log-phase cultures varied from about 6 to 30 in several rodent lines. The SSV-NRK rat cell line has 6 +/- 0. 2 molecules/cell, while mouse NIH3T3 cells have about 30 +/- 1 molecules/cell. If the mRNA level is indicative of the level of the active MPG enzyme, these results may imply a variation in the capacity of various lines to remove the cytotoxic and mutagenic adducts from DNA.

Two fractions of the DOM, free amino acids (DFAA) and monosaccharides (MONO), were measured at 3 h intervals in mixed species dinoflagellate blooms (Katodinium rotundatum, Gymnodinium spp.) and related to productivity, biomass and photoperiod. Peak chlorophyll levels for the three blooms were 28, 65 and 938 mu g l (super -1) . In general, DFAA and MONO concentrations increased with increasing biomass of bloom-forming species, reaching 203 and 844 mu g l (super -1) . MONO appeared to accumulate during the day while there was no consistent pattern for DFAA. The accumulations of DFAA and MONO in blooms indicate that bloom production might stimulate microheterotrophy, thereby enhancing carbon and nutrient cycling in bloom-impacted regions.

It is the most saline of the Antarctic lakes, being a near-saturated CaCl (sub 2) solution. As a consequence of this high salinity, Don Juan Pond generally remains unfrozen in winter, even at temperatures below -50 degrees C. Don Juan Pond is the site where antarctite (CaCl (sub 2) .6H (sub 2) O) was first identified forming naturally. The objective of this paper is to demonstrate the utility of a chemical thermodynamic model (FREZCHEM) by developing theoretical stability diagrams for ice, halite (NaCl), hydrohalite (NaCl.2H (sub 2) O), and antarctite in Don Juan Pond, using experimental data collected on 34 days between 1961 and 1983. The composition of Don Juan Pond at the calculated eutectic temperature (-51.8 degrees C) was CaCl (sub 2) = 3.72 mol kg (super -1) and NaCl = 0.50 mol kg (super -1) ,which is similar but not identical to a pure NaCl-CaCl (sub 2) -H (sub 2) O system. The low eutectic temperature and high CaCl (sub 2) concentrations of Don Juan Pond account for lack of freezing during winter. The model is compatible with the experimental data, and predicts the formation of ice during rare high water periods, halite, and antarctite. These solid phases have all been reported from Don Juan Pond. The model also predicts the formation of hydrohalite at subzero temperatures; hydrohalite has never been observed at Don Juan Pond, but this may simply reflect that most sampling was done during the summer when halite is thermodynamically more stable than hydrohalite. The FREZCHEM model may prove useful in elucidating the physiochemical behaviour, the origin of salinity, and the evolution of Antarctic lakes.

In the laboratory, specimens of three GCLs were frozen and thawed 20 times, and no increase in hydraulic conductivity was measured. The hydraulic conductivity of the compacted sand-bentonite also did not increase after freezing and thawing. In the field, two types of GCLs and a sand-bentonite test pad (constructed with the same mixture used in the laboratory) were exposed to one or two winters of freeze-thaw cycling. No large increase in hydraulic conductivity was measured for the field test conducted with the sand-bentonite mixture. An increase in hydraulic conductivity was observed in only one of the field tests with GCLs. Examination of thawed GCLs and specimens of the sand-bentonite mixture showed no evidence of cracking that is commonly found in thawed compacted clays.

Clear returns were obtained from the air/snow, snow/ice, ice/water, and ice/ground interfaces. Surface-to-bottom signal intensity ratios are within ranges predicted by plane wave reflection theory, use of which also gives plausible permittivity values for the ice-rich bottom silts. Scattering losses are interpreted for the X-band ice-bottom signals, but evidence of increased volumetric scattering loss with increasing ice thickness may have been masked by changes in bottom dielectric contrasts. The results suggest that this type of radar is superior to conventional transient GPR systems for this application and ice grounded to almost any type of bottom sediments could be profiled from an airborne platform. Such a system could help inventory wetland water volume in northern regions.

Grouse moved 1-69 km (x super(-) = 17.8 plus or minus 2.0 km [SE]; N = 81) from breeding and nesting areas to summer ranges, predominantly in northwest or southwest directions during the 6-year period. There was no difference in timing, distance, or direction moved between birds captured in burned and unburned habitats. The data provided further evidence of traditional migration routes for Sage Grouse breeding and nesting in the Big Desert.

The objective of this study was to compare the efficacy of biodegradable, poly (DL-lactide-co-glycolide) cefazolin microspheres and free cefazolin powder in Staphylococcus aureus contaminated rabbit tibial fractures when treatment was delayed for 2 hours. Fractures were produced in the tibia of rabbits, inoculated with Staphylococcus aureus, and 2 hours later treated by either direct local application of cefazolin microspheres or an equivalent dose of free cefazolin powder. Control animals did not receive antibiotic therapy. The fractures then were stabilized with a bone plate, and the animals were observed for 8 weeks. Local antibiotic therapy with biodegradable cefazolin microspheres prevented the establishment of infection in all animals, and cultures of the tibiae were sterile in all cases. In contrast, clinical evidence of infection developed in 50% of the rabbits that had been treated with free cefazolin powder and 71% of the control animals. Staphylococcus aureus was recovered from the tibiae of 75% and 100% of these animals, respectively. The results of this study suggest that local antibiotic therapy with biodegradable, controlled release cefazolin microspheres may be useful for the management of open fractures in humans, even when treatment is delayed for several hours after bacterial contamination.

Major invertebrate taxa were copepods (Cyclopoida, occurred in 8.3% of samples), water fleas (Daphnidae, 8.9%), water boatmen (Corisella, 10.4%), and midge larvae (Goeldichironomus, 9.3%; Chironomus, 11.5%; Tanypus, 17.2%). We found no treatment (carcass present or no carcass) by sampling day interaction for these taxa. We found a significant difference between sample plots with carcasses and those without carcasses only for Daphnidae counts and Corisella wet weights. We found significant differences among sampling days for these taxa that were probably statistical artifacts. We were unable to detect any effect of duck carcasses on aquatic invertebrate community structure and the potential availability of invertebrates as waterfowl food.

This record was used to monitor atmosphere, ice and ocean temperatures, determine changes in the ice mass balance, and infer estimates of the ocean heat flux and the snow thermal conductivity. Ablation during the summer melt season consisted of approximately 0.3 m of snow melt, 0.67 m of ice surface ablation and 0.25 m of bottom ablation. There was 0.45 m of bottom accretion during the growth season. The annually averaged ocean heat flux was 4 W m super(-2), with a summertime value of 9 W m super(-2). Comparing these results to earlier studies conducted in the same region showed considerable interannual variability in summer melting. The thermal conductivity of snow cover was approximately 0.3 W m super(-1) K super(-1) during winter.

AN - 78819236; 9038195 AB - To determine the effect of various stereoisomers of benzo[a]pyrene-7,8-dihydrodiol 9,10-epoxide (BPDE) on translesion bypass by human immunodeficiency virus-1 reverse transcriptase and its alpha-helix H mutants, six 33-mer templates were constructed bearing site- and stereospecific adducts. This in vitro model system was chosen to understand the structure-function relationships between the polymerase and damaged DNA during replication. Comparison of the replication pattern between wild type human immunodeficiency virus-1 reverse transcriptase and its mutants, using primers which were 3' to the lesion, revealed essentially similar patterns. While these primers terminated with all three of the C10R and two of the C10S BPDE-adducted templates 1 base 5' and 1 base 3' to the damaged site respectively, (+)-anti-trans-(C10S) BPDE-adducted DNA alone permitted the formation of full-length products. Utilization of a primer with its 3'-hydroxyl 1 base beyond the lesion resulted in full-length products with all the C10S BPDE-adducted templates and the (-)-syn-trans-(C10R)-BPDE-adducted template, following replication with either the wild type or mutant enzymes. However, the other two C10R BPDE-adducted templates failed to allow any primer extension, even with the wild type enzyme. Although T.P depletion studies further confirmed the differential primer extension abilities using the C10R and C10S adducted templates, their binding affinities were similar, yet distinct from the unadducted template.

AN - 78877017; 9066029 AB - Superantigens produced by Staphylococcus aureus can cause food poisoning and toxic shock syndrome. The biological activities and vaccine potential of mutant staphylococcal enterotoxin B (SEB) proteins, N23K and F44S, were studied in a lipopolysaccharide-potentiated mouse model. Although 10 micrograms of SEB per mouse is equivalent to 30 LD50, the same intraperitoneal dose of either mutant protein was nonlethal and did not elevate serum levels of tumor necrosis factors (TNF). N23K, F44S, and SEB were serologically identical in an enzyme-linked immunosorbent assay with polyclonal anti-SEB. Immunization with alum containing N23K, F44S, or SEB elicited an anti-SEB response that protected 80-87% of the mice against a 10 micrograms SEB challenge. Controls lacking an anti-SEB titer did not survive. Pooled sera from immunized mice effectively blocked SEB-induced T-cell proliferation in vitro. Naive mice survived a lethal SEB challenge when given pooled antisera 1, 2, or 4 h later, whereas the antisera failed to protect animals when administered 6 or 8 h after the toxin. Lethality at the later times was consistent with increased serum levels of TNF observed 6 h after SEB injection. These studies suggest that the N23K and F44S mutant proteins of SEB are less biologically active than the wild-type toxin, yet retain epitopes useful for eliciting a protective antibody response.

AN - 78860051; 9063578 AB - The binding characteristics of saxitoxin (STX), a known voltage-gated sodium channel blocker, and its analog saxitoxinol (STXOL), were studied in neuroblastoma, peritoneal macrophage, hepatocytes and PC-12 cell lines. 3H-STXOL bound to the cell-surface sites which appear to be the same as those occupied by 3H-STX and which can, therefore, be identified as STX receptors. The relative agreement of respective Kd obtained by saturation, competition, association and dissociation kinetics for STX and STXOL suggest the absence of any artifact in binding measurements. Unlike STX, STXOL was non-toxic to mice by intratracheal instillation. The major advantage of using 3H-STXOL is that the tritium label is not exchangeable. Data from this study suggest that 3H-STXOL can be used to identify STX receptors at 37 degrees C.

AN - 78829987; 9038034 AB - Researchers at the U.S. Army Research Institute of Environmental Medicine have developed and validated numerical models capable of predicting the extent of physiologic strain and adverse terrain and weather-related medical consequences of military operations in harsh environments. A descriptive historical account is provided that details how physiologic models for hot and cold weather exposure have been integrated into portable field advisory devices, computer-based meteorologic planning software, and combat-oriented simulation systems. It is important that medical officers be aware of the existence of these types of decision support tools so that they can assure that outputs are interpreted in a balanced and medically realistic manner. Additionally, these modeling applications may facilitate timely preventive medicine planning and efficient dissemination of appropriate measures to prevent weather- and altitude-related illnesses and performance decrements. Such environmental response modeling applications may therefore be utilized to support deployment preventive medicine planning by field medical officers.

AN - 78825327; 9039976 AB - In an effort to understand the pathophysiology of sulfur mustard (2,2' dichlorodiethyl sulfide, HD)-induced cutaneous lesions, a number of animal models have been used. Animal models have been and will continue to be used in the development of therapeutic strategies to protect against and/or moderate lesions, and to potentiate wound healing after HD exposure. Upon reviewing the histopathologic features seen after HD-exposure, we propose roles for different animal models in HD-research. Hematoxylin and eosin slides from protocols done originally as dose response studies for either liquid or vapor HD-exposures were examined. The animal models reported include the hairless guinea pig (HGP), weanling pig (WP), mouse ear (ME) and hairless mouse (HM). In all these animal models. HD induces subepidermal blister formation as well as epidermal cell death. The HGP appears to be the most sensitive model for epidermal necrosis. The HGP and, to a lesser degree, the HM react with a marked neutrophilic infiltrate. The ME provides a quantitative measure for HD effects and a mild inflammatory infiltrate similar to what is seen in human skin. Doses necessary to produce microblister formation in the WP are usually associated with more significant stromal and vascular changes than in other animal models. In addition to a quantitative measure of the HD effect and a mild inflammatory response, the cost, as well as the availability of specific antibodies, and DNA and RNA probes and primers gives the ME advantages for both drug screening and for the study of the pathophysiology of HD-induced cutaneous lesions. The sensitivity of the HGP and the abundant experience with vapor exposures establishes a place for this animal model in barrier cream and drug screening. The similarity of WP skin to human skin is important in the study of wound healing after HD exposure, as well as in the study of the pathophysiology of the cutaneous lesion and in more definitive therapeutic studies.

Military Medical Consortium for the Advancement of Retroviral Research (MMCARR). AN - 78825168; 9039176 AB - Although intralesional vinblastine has been used with some success in the treatment of cutaneous lesions of Kaposi's sarcoma (KS), lesions commonly recur. When large lesions are treated, frequently there is considerable discomfort and, in some cases, secondary ulceration. Hyaluronidase has been used to increase dispersion of drugs administered by local injection. Our purpose was to determine whether intralesional hyaluronidase administered before intralesional vinblastine increases the dispersion of vinblastine and decreases toxicity. We treated six patients who had multiple cutaneous plaque lesions and tumors of KS with intralesional vinblastine, intralesional vinblastine preceded by intralesional hyaluronidase, or intralesional hyaluronidase alone. Both intralesional vinblastine and intralesional vinblastine preceded by intralesional hyaluronidase caused clinical regression of lesions of KS; however, the combination of hyaluronidase and vinblastine was more effective in treating tumor nodules. In addition, lesions treated with hyaluronidase and vinblastine recurred less often than those treated with vinblastine alone and showed no evidence of residual KS in two patients undergoing biopsy between 4 and 6 months after therapy. Intralesional hyaluronidase enhances vinblastine in the treatment of cutaneous lesions of KS without adding to the systemic toxicity.

Mean annual P retention was similar to mean annual P sedimentation, as estimated from sediment core rates integrated over the entire lake basin, indicating that annual P mass balance approximated annual net P sedimentation in this reservoir. However, sediment trap P rates, measured over the summer stratified period, overestimated P retention rates determined over the same period, suggesting substantial deposition of internally-derived P. Inclusion of measured internal P loadings from a variety of sources in Eau Galle Reservoir in a P mass balance only accounted for an additional 24% of the summer sediment trap P rate, indicating substantial uncertainty in the overall P budget. Imbalances in the P budget may also suggest deposition of sediment from other as yet unquantified internal sources. Potential internal sources of P include sediment resuspension and chemical release and direct uptake of P from the sediment by phytoplankton.

Skilled bowfishers, who were paid a bounty of US$50.00 per fish, collected 69, 125, and 160 triploid grass carp in 1992, 1993, and 1994, respectively. Fish were fully vulnerable to bowfishing by age 2. Examination of sectioned utricular otoliths (lapilli) revealed annual marks formed during May-June. Weight (W) increased linearly with age (t, years), for ages 1-6; W = -2,360 + 3,016t. Age-specific weights ranged from 0.39 kg to 15.68 kg for fish of ages 1-6. The weight to total length (TL, mm) relation varied little during the study and was W = 0.00000425(TL) super(3.185). A von Bertalanffy growth equation was fitted to describe the relation between length and age. TL sub(t) = 1,044(1 - e super(-0.615(t - 0.590))). The annual rate of mortality was 22% in 1994. We estimate that 350,000 triploid grass carp, weighing about 2,000,000 kg, were present in the system as of August 1994; this represented approximately 17 grass carp, or 97 kg, per vegetated hectare. Collection and aging techniques developed in this study may have application in places where triploid grass carp are conservatively and incrementally stocked into large systems. In this regard, population density and growth can be monitored and future stockings adjusted accordingly.

Larval northern pike population densities declined significantly between the first (25 April) and second (8 May) sampling periods, indicating mortality or emigration from the wetlands; only two northern pike were captured on 26 May. Larval northern pike population densities were higher in artificial wetlands on 25 April, but on 8 May no difference could be detected. Mean total length of larvae was greater in artificial wetlands on 25 April and 8 May. Larval northern pike began feeding at approximately 15 mm total length. No difference in number of food items eaten was detected between natural and artificial wetlands; however, percentage of copepods, the taxa most commonly eaten, was higher in northern pike stomachs from natural wetlands. Cannibalism was observed in 1 of the 76 stomachs examined and constituted the only vertebrate food item found.

The U.S. Army Corps of Engineers employed one-dimensional and two-dimensional numerical models to design temporary underwater sill that would limit upstream salinity intrusion. The sill was constructed and successfully protected the freshwater supplies of the New Orleans area with cost savings of over $50,000,000. Postdrought analysis showed that the models accurately predicted behavior of the salt wedge and the sill.

Simulated shoreline change over a 70-month period is compared to measure shoreline change for the same period. Shoreline change simulations were performed using seven different descriptions of the input incident wave conditions. Also examined is the influence of using estimates of wave conditions concurrent with the simulation period versus using representative wave conditions selected from a 20-yr database of hindcast wave conditions. The findings indicate that a more representative shoreline planform shape is predicted when the input wave specification includes alongshore variability due to wave transformation over the nearshore bathymetry. At sites where the nearshore contours are straight and parallel to the shoreline, there is little alongshore variability in the breaking wave conditions and inclusion of nearshore wave information in the input wave specification is less important. Although an improved prediction of shoreline change is obtained when nearshore wave conditions are used, ambiguity surrounds selection of an appropriate bathymetric grid resolution for nearshore wave transformation. Finally, it was found that the inclusion of nearshore wave information in the input wave specification is likely to improve the modeling result more than using offshore wave information concurrent with the period of evolution.

Reaction time and decision-making speed were assessed using a series of simple and choice reaction time tasks at the start of each test iteration and after hours 2, 4, 6, 8, and 10 of testing. Subject anxiety levels were assessed along with reaction time measures. Visual tracking ability was measured after each hour of testing. Reaction time and decision-making speed did not differ significantly between control and respirator conditions at any time throughout the 10 hours of testing. Female volunteers exhibited significantly faster reaction times and decision-making speeds than males independent of respirator wear conditions and time of measurement. Subject anxiety increased significantly from initial measurements after 8 hours of testing for each condition, but no differences were observed between conditions at any time. Respirator wear did not detrimentally influence visual tracking ability. These findings suggest that respirator wear over a relatively long time period under nonexercise conditions should not significantly inhibit cognitive function.

AN - 78817808; 9037714 AB - Ricin A-chain is a cytotoxic protein that attacks ribosomes by hydrolyzing a specific adenine base from a highly conserved, single-stranded rRNA hairpin containing the tetraloop sequence GAGA. Molecular-dynamics simulation methods are used to analyze the structural determinant for three substrate analogues bound to the ricin A-chain molecule. Simulations were applied to the binding of the dinucleotide adenyl-3',5'-guanosine employing the x-ray crystal structure of the ricin complex and a modeled CGAGAG hexanucleotide loop taken from the NMR solution structure of a 29-mer oligonucleotide hairpin. A third simulation model is also presented describing a conformational search of the docked 29-mer structure by using a simulated-annealing method. Analysis of the structural interaction energies for each model shows the overall binding dominated by nonspecific interactions, which are mediated by specific arginine contracts from the highly basic region on the protein surface. The tetraloop conformation of the 29-mer was found to make specific interactions with conserved protein residues, in a manner that favored the GAGA sequence. A comparison of the two docked loop conformations with the NMR structure revealed significant positional deviations, suggesting that ricin may use an induced fit mechanism to recognize and bind the rRNA substrate. The conserved Tyr-80 may play an important conformational entropic role in the binding and release of the target adenine in the active site.

In the first year, 20 different tubings were compared, under static conditions, with respect to sorption of organic contaminants and leaching of organic constituents. In this study, the authors examined what occurs under dynamic conditions when TCE-contaminated water is pumped through several different types of polymeric tubings. Sorption of organic solutes, leaching of organic constituents, and desorption of sorbed organic contaminants were all examined. Five tubings were selected for this study: a rigid fluoropolymer, a flexible fluoropolymer, low-density polyethylene (LDPE), and two plasticized polypropylene tubings. These materials were selected because the static studies had shown that these tubings leached little or no organic constituents (as determined by HPLC analyses with an ultraviolet [UV] detector) and ranged from being the least sorptive tubings tested to among the most highly sorptive. The effects of tubing length and flow rate were examined. Results from these studies indicate that if water is pumped through tubing at a slow flow rate (100 mL/min), fluoropolymers should be used to prevent extensive losses of TCE and more sorptive analytes, especially if the tubing is 50 ft or longer. If a faster flow rate (1 L/min) is used, it appears that LDPE tubing can be used to sample TCE and other less sorptive analytes, although time for equilibration (2-4 hr) should be allowed to reduce losses in the deepest wells.

The tools provided decision makers with information about the costs and benefits of alternatives for environmental restoration and watershed projects and their associated tradeoffs. The analyses required a list of solutions and estimates of their outputs and costs. Cost estimates needed to include both financial implementation and economic opportunity costs. Calculation of incremental cost data is discussed. Examples of accounting for both intended and unintended effects of alternative solutions are given.

Hydraulic and solids loading rates for reed beds are quantified. Alternative sludge dewatering options are outlined, including land application, mechanical dewatering, wedgewater beds, vacuum-assisted beds, wedgewater beds followed by composting and sand beds. The operational performance of the reed bed is summarized. The advantages of reed beds were low investment, simplicity, the absence of sludge disposal problems and the eventual production of a composted soil by-product. Limitations included the large land area, the long preparation period of more than one year, the presence of pathogens in the top layer and the need for excavation technologies suitable for reed beds.

The application of turbulence theory to model systems and the modelling of 2-dimensional advection-dispersion processes were examined and special studies were made of the behaviour of jets and plumes. Measurement techniques were applied to a variety of situations, and reports are reviewed under the headings of riverine systems, lacustrine systems, estuarine systems and coastal water systems, and pelagic marine systems. The mixing processes occurring in all these situations were the focus of intensive studies to assess the dispersion of pollutants in the natural environment, including the behaviour of effluent plumes emerging from marine outfalls. Other aspects briefly referred to involved the interactions with biota, the motion of surface films such as oil slicks, gas transfer at the water/air interface, and the transport of suspended sediments under the influence of hydrodynamic variables, including the effect of wind action.

Harmonic analysis, time-scale analysis and conventional methods of hydrological analysis of gauge data at decade intervals showed a steady decline in the magnitude and predictability of the baseflow during low flow periods (less than 5.7 m3 per second) from the 1920s, becoming increasingly pronounced into the 1980s. Hydroperiod alterations were associated with increased groundwater pumping to support rice agriculture in the basin. These hydroperiod changes may explain changes in the biotic communities or wetlands structure. There are 33 references.

Any external forcing that can cause the balance between the terminal ice flux and calving flux to shift can influence advance, retreat and stillstand phases. Recent studies in Glacier Bay, Alaska, document periods of terminus stabilization and moraine formation. In this paper, the recent histories of Grand Pacific and Muir glaciers are presented. Grand Pacific Glacier advanced through most of the last half century while Muir Glacier only recently stabilized after 100 years of retreat. Their dynamics appear unrelated to climatic forcing, but instead reflect internal adjustments to calving and glacier dynamics.
