Volcanically induced cooling of the ocean surface penetrated into deeper layers, where it persisted for decades after the event. This remarkable effect on oceanic thermal structure is longer lasting than has previously been suspected and is sufficient to offset a large fraction of ocean warming and sea-level rise caused by anthropogenic influences.

AN - 70716660; 16435922 AB - We have developed and validated a practical approach to identifying the location on the skin surface that will receive a prespecified biopsy dose (ranging down to 1 cGy) in support of in vivo biological dosimetry in humans. This represents a significant technical challenge since the sites lie on the patient's surface outside the radiation fields. The PEREGRINE Monte Carlo simulation system was used to model radiation dose delivery, and TLDs were used for validation on phantoms and for confirmation during patient treatment. In the developmental studies, the Monte Carlo simulations consistently underestimated the dose at the biopsy site by approximately 15% (of the local dose) for a realistic treatment configuration, most likely due to lack of detail in the simulation of the linear accelerator outside the main beam line. Using a single, thickness-independent correction factor for the clinical calculations, the average of 36 measurements for the predicted 1-cGy point was 0.985 cGy (standard deviation: 0.110 cGy) despite patient breathing motion and other real-world challenges. Since the 10-cGy point is situated in the region of high-dose gradient at the edge of the field, patient motion had a greater effect, and the six measured points averaged 5.90 cGy (standard deviation: 1.01 cGy), a difference that is equivalent to approximately a 6-mm shift on the patient's surface.

The oxygen fugacity during the runs was between the iron-wustite and Ni/NiO buffers. The water content of the polycrystalline samples was generally approximately 150-200 ppm but was as low as 35 ppm. Typically, 30% strain was generated during the uniaxial compression. Sample lengths and differential stresses were monitored in situ by X-ray radiography and diffraction, respectively. The strain rate was derived with an accuracy of 10 (super -6) /s. Differential stress was measured at constant strain rate ( approximately 10 (super -5) /s) using a multi-element solid-state detector in combination with a conical slit. Recovered specimens wre studied by optical and TEM, the latter showing that dislocation glide was the dominant deformation mechanism throughout the experiment. Defomation data show little or no dependence of the dislocation creep flow with pressure, yielding to an activation volume V* of 0 + or - 5 cm (super 3) /mol. These results are consistent with the high-temperature rheological laws at lower pressure.

Although the rate at which large rivers incise rock is a fundamental control on the development of landscapes, relatively few studies have directly measured how quickly such incision occurs either in tectonically active environments or along passive margins. Exposure ages of fluvially carved, bedrock strath terraces, preserved along the lower Susquehanna River, demonstrate that even along a passive margin, large rivers are capable of incising through rock for short periods of time at rates approaching those recorded in tectonically active regions, such as the Himalayas. Over eighty samples, collected along and between three prominent levels of strath terraces within Holtwood Gorge, indicate that the Susquehanna River incised more than 10 meters into the Appalachian Piedmont during the last glacial cycle. Beginning approximately 36 ka, incision rates increased dramatically, and remained elevated until approximately 14 ka. The northern half of the Susquehanna basin was glaciated during the late Wisconsinan; however, similar rates and timing of incision occurred in the unglaciated Potomac River basin immediately to the south. The concurrence of incision periods on both rivers suggests that glaciation and associated meltwater were not the primary drivers of incision. Instead, it appears that changing climatic conditions during the late Pleistocene promoted an increase in the frequency and magnitude of flood events capable of exceeding thresholds for rock detachment and bedrock erosion, thus enabling a short-lived episode of rapid incision into rock. Although this study has constrained the timing and rate of bedrock incision along the largest river draining the Atlantic passive margin, the dates alone cannot explain fully why, or by what processes, this incision occurred. However, cosmogenic dating offers compelling evidence that episodes of rapid incision into bedrock are tied to glacial cycles and changes in global climate. These results, and the methods we employ, provide valuable insights into the nature of bedrock channel incision, not only along the Susquehanna River and passive margins, but also across a wide range of settings around the globe. Because river incision into bedrock transmits the effects of changing climate and tectonics through fluvial networks to hillslopes, comprehending when, where, and why rivers incise has important implications for the evolution of landscapes.

Total organic carbon (TOC) and higher plant biomarker mass accumulation rates were an order of magnitude greater during the last glacial period compared to the current interglacial due to sea-level controlled variations in Amazon River sediment supply. Large maxima were also seen at approximately 12 ka, which are most likely due to discharge events. Higher plant n-alkane average chain lengths did not change throughout the record, suggesting consistency in the source vegetation type. The abundance of taraxerol relative to other plant biomarkers increased at approximately 12 ka, indicating increased mangrove input due to either higher mangrove productivity or increased erosion of mangrove deposits. The mass accumulation rates (MARs) of some bacterial and eustigmatophyte biomarkers varied closely with those of higher plant biomarkers and so seem to have a non-marine source. Long chain alkenones were present in some of the sediments, generally in very low concentration, indicating dilution of the marine signal with terrestrial organic matter.

Analysis of the 2,909,809-bp genome will facilitate our molecular and biochemical understanding of the unusual metabolic repertoire of this bacterium, including its ability to couple denitrification to sulfur-compound oxidation, to catalyze anaerobic, nitrate-dependent oxidation of Fe(II) and U(IV), and to oxidize mineral electron donors. Notable genomic features include (i) genes encoding c-type cytochromes totaling 1 to 2 percent of the genome, which is a proportion greater than for almost all bacterial and archaeal species sequenced to date, (ii) genes encoding two [NiFe]hydrogenases, which is particularly significant because no information on hydrogenases has previously been reported for T. denitrificans and hydrogen oxidation appears to be critical for anaerobic U(IV) oxidation by this species, (iii) a diverse complement of more than 50 genes associated with sulfur-compound oxidation (including sox genes, dsr genes, and genes associated with the AMP-dependent oxidation of sulfite to sulfate), some of which occur in multiple (up to eight) copies, (iv) a relatively large number of genes associated with inorganic ion transport and heavy metal resistance, and (v) a paucity of genes encoding organic-compound transporters, commensurate with obligate chemolithoautotrophy. Ultimately, the genome sequence of T. denitrificans will enable elucidation of the mechanisms of aerobic and anaerobic sulfur-compound oxidation by beta -proteobacteria and will help reveal the molecular basis of this organism's role in major biogeochemical cycles (i.e., those involving sulfur, nitrogen, and carbon) and groundwater restoration.

Adjusted data analyzed involve a total of 19,828 events, 7,401 'adverse' events (each causing greater than or equal to 1 victim), and 86,568 'casualties' (injuries), of which 25,408 were fatal. Most terror-related adverse events, casualties, and deaths involved bombs and guns. Weapon-specific patterns and terror-related risk levels in Israel (IS) have differed markedly from those of all other regions combined (OR). IS had a fatal fraction of casualties about half that of OR, but has experienced relatively constant lifetime terror-related casualty risks on the order of 0.5%-a level 2 to 3 orders of magnitude more than those experienced in OR that increased approximately 100-fold over the same period. Individual event fatality has increased steadily, the median increasing from 14% to 50%. Lorenz curves obtained indicate substantial dispersion among victim-event rates: about half of all victims were caused by the top 2.5% (or 10%) of harm-ranked events in OR (or IS). Extreme values of victim-event rates were approximated fairly well by generalized Pareto models (typically used to fit to data on forest fires, sea levels, earthquakes, etc.). These results were in turn used to forecast maximum OR- and IS-specific victims-event rates through 2080, illustrating empirically-based methods that could be applied to improve strategies to assess, prevent, and manage terror-related risks and consequences.

As measures of the 'reproducibility' of continental climate for different initial conditions, spatiotemporal correlations are computed across paired realizations of 11 model land surface variables in which the seasonal cycle is either included or excluded-the former case being pertinent to climate simulation and the latter to seasonal prediction. It is found that the land surface variables that include the seasonal cycle are impacted only marginally by changes in initial conditions; moreover, their seasonal climatologies exhibit high spatial reproducibility. In contrast, the reproducibility of a seasonal land surface anomaly is generally low, although it is substantially higher in the Tropics; its spatial reproducibility also markedly fluctuates in tandem with warm and cold phases of the El Nino-Southern Oscillation. However, the overall degree of reproducibility depends on the particular land surface anomaly considered. It is also shown that the predictability of a land surface anomaly implied by its reproducibility statistics is consistent with what is inferred from more conventional predictability metrics. Implications of these results for climate model intercomparison projects and for operational forecasts of seasonal continental climate also are elaborated.

A long-standing problem with such models is that when different components of the physical climate system are linked together, the simulated climate can drift away from observation unless constrained by ad hoc adjustments to interface fluxes. However, 11 modern coupled GCMs, including three that do not employ flux adjustments, behave much better in this respect than the older generation of models. Surface temperature trends in control run simulations (with external climate forcing such as solar brightness and atmospheric carbon dioxide held constant) are small compared with observed trends, which include 20th century climate change due to both anthropogenic and natural factors. Sea ice changes in the models are dominated by interannual variations. Deep ocean temperature and salinity trends are small enough for model control runs to extend over 1000 simulated years or more, but trends in some regions, most notably the Arctic, differ substantially among the models and may be problematic. Methods used to initialize coupled GCMs can mitigate climate drift but cannot eliminate it. Lengthy 'spin-ups' of models, made possible by increasing computer power, are one reason for the improvements this paper documents. JF - Journal of Geophysical Research.

In 1975, groundwater adjacent to the Cambric test, conducted beneath Frenchman Flat 10 years earlier, was pumped steadily for 16 years to elicit information on the migration of residual radioactivity through the saturated zone. Radionuclides in the pumping well effluent, including tritium, (super 14) C, (super 36) Cl, and (super 85) Kr, were extensively monitored prior to its discharge in an unlined ditch, where approximately a third of the flow infiltrated over a distance of 1 km. Radionuclide infiltration through a 220-m thick vadose zone created a second, and rather unique long-term field experiment. Effluent data have been utilized in conjunction with geologic data, new radionuclide measurements, isotopic age-dating estimates, and vadose zone flow and transport models to better understand the movement of radionuclides between the ditch, the water table and a nearby groundwater monitoring well. Detection of tritium in the monitoring well occurred approximately 16 years after its initial discharge into the ditch. Modeling and tritium age dating have suggested 3-5 years of this 16-year transit time occurred solely in the vadose zone. They also suggest considerable recirculation of the pumping well discharge back into the original pumping well. Notably, there have been no observations of (super 14) C or (super 85) Kr in the monitoring well, suggesting their preferential retention or volatilization during transit to the water table. f this 16-year transit time occurred solely in the vadose zone. They also suggest considerable recirculation of the pumping well discharge back into the original pumping well. Notably, there have been no observations of (super 14) C or (super 85) Kr at the water table, suggesting their preferential retention or volatilization during transit to the water table. Overall, the long-term nature of the experiment, the variety of chemical measurements and isotopic interpretations, and their incorporation into a unified modeling analysis, have contributed to a unique perspective for interpreting radionuclide migration in a deep unsaturated system.

The PLANET collaboration of researchers maintains a high sampling rate required to detect low-mass planets while monitoring the most promising of the > 500 microlensing events discovered annually. Two Jupiter-mass extra-solar system planets have recently been detected. On 11.7.2005 a microlensing event was discovered (right ascension alpha = 17 hr 54 min 19.2sec, declination delta = -30 degrees 22' 38'', J2000), with a relatively bright clump giant as a source star, and subsequent observations detected a short-duration deviation from a single lens light curve attributed to a low-mass planet orbiting the lens star. Details of the discovery are presented including the Bayesian probability densities for the planet (OGLE-2005-BLG-390Lb) and its host star. This discovery indicates that such cool, sub-Neptune-mass planets may be more common than gas giant planets as predicted by the core accretion theory.

AN - 67997651; 16650918 AB - Bikini Island was contaminated on March 1, 1954 by the Bravo detonation (U.S. nuclear test series, Castle) at Bikini Atoll. About 90% of the estimated dose from nuclear fallout to potential island residents is from cesium-137 ((137)Cs) transferred from soil to plants that are consumed by residents. Thus, radioecology research efforts have been focused on removing (137)Cs from soil and/or reducing its uptake into vegetation. Most effective was addition of potassium (K) to soil that reduces (137)Cs concentration in fruits to 3-5% of pretreatment concentrations. Initial observations indicated this low concentration continued for some time after K was last applied. Long-term studies were designed to evaluate this persistence in more detail because it is very important to provide assurance to returning populations that (137)Cs concentrations in food (and, therefore, radiation dose) will remain low for extended periods, even if K is not applied annually or biennially. Potassium applied at 300, 660, 1260, and 2070 kg ha(-1) lead to a (137)Cs concentration in drinking-coconut meat that is 34, 22, 10, and about 4% of original concentration, respectively. Concentration of (137)Cs remains low 8-10 y after K is last applied. An explanation for this unexpected result is discussed.

AN - 67728882; 16522646 AB - Homologous recombinational repair (HRR) restores chromatid breaks arising during DNA replication and prevents chromosomal rearrangements that can occur from the misrepair of such breaks. In vertebrates, five Rad51 paralogs are identified that contribute in a nonessential but critical manner to HRR proficiency. We constructed and characterized a knockout of the paralog Rad51D in widely studied CHO cells. The rad51d mutant (clone 51D1) displays sensitivity to a diverse spectrum of induced DNA damage including gamma-rays, ultraviolet (UV)-C radiation, and methyl methanesulfonate (MMS), indicating the broad relevance of HRR to genotoxicity. Spontaneous chromatid breaks/gaps and isochromatid breaks are elevated 3- to 12-fold, but the chromosome number distribution remains unchanged. Most importantly, 51D1 cells exhibit a 12-fold-increased rate of hprt mutation, as well as 4- to 10-fold increased rates of gene amplification at the dhfr and CAD loci, respectively. Xrcc3 irs1SF cells from the same parental CHO line show similarly elevated mutagenesis at these three loci. Collectively, these results confirm the a priori expectation that HRR acts in an error-free manner to repress three classes of genetic alterations (chromosomal aberrations, loss of gene function and increased gene expression), all of which are associated with carcinogenesis.

The basal and internal structure is imaged in detail showing basal erosion and evidence for at least three phases of landslide failure. Landslide internal structure reveals evidence for seafloor remobilization during the initial phase of submarine landslide failure. Missing strata and downslope-trending striations 15 m deep and 9 km long on the basal sliding surface record the initial failure over an area >130 km (super 2) . The basal striations originate from and extend downslope from a major growth fault trending NW-SE. We speculate that fluid flow or seismicity associated with this growth fault triggered landsliding. The landslide deposit consists of large blocks (approximately 1 to >5 km across and approximately 100 to 150 m thick) which have slid, rotated, and deformed in the landslide within a chaotic debris-flow matrix. A smoother debris-flow morphology extends from the erosional scars and blocks to the SE beyond the boundaries of the survey area. A rough estimate of landslide geometry indicates that the deposit volume is double the volume of erosional slide scars within 5 km of source. The observations from this study are summarized in a process-oriented landslide model. Results provide insight into the triggering, evolution, and runout potential of giant submarine landslides.

There is a wide variety of mining algorithms and tools available for both predictive and descriptive data mining that have been applied on a variety of geoscience problems. This paper provides a high-level overview of the data-mining process, several mining algorithms and tools, and their application to the geosciences. It also describes the geoscience data characteristics that make mining these data a challenge, and details some of the common data preparation operations that are required to make the geoscience data ready for mining. Three data-mining applications are presented in detail in this paper to demonstrate the usefulness of data mining to solve specific geoscience problems. Issues relevant in determining a successful data-mining application in geoscience are presented as lessons learned. Finally, the paper looks at challenges ahead by focusing on two relevant research areas for data mining and geosciences: mining streaming data in real time and exploiting the emerging cyberinfrastructure for mining.

We present exposure ages for large boulders on the delta surface, which coupled with preservation of relict landforms demonstrate that the region was covered by minimally erosive, cold-based ice during the late Wisconsinan. Our data suggest that surficial features commonly used to define the pattern of late Wisconsinan ice movement cannot be used on their own to constrain late Wisconsinan ice-sheet margins in Arctic regions.

Escarpments reflect the morphotectonic development of passive margins and can separate regions with different climatic histories, but the inferred rapid rates of escarpment retreat have been at odds with actual measurements of land surface denudation. In this paper we present results from extensive cosmogenic (super 10) Be and (super 26) Al analyses across the escarpment of southeastern Australia to quantify the erosional processes evolving the highland, lowland, and scarp face landscapes. We document new relationships between soil production rates and soil thicknesses for the highland and lowland landscapes and compare these soil production functions with those published in our earlier studies from the highlands and at the base of the escarpment. Both new functions define exponential declines of soil production rates with increasing soil depths, with inferred intercepts of 65 and 42 m/m.y. for the highland and lowland sites, respectively, and slopes of -0.02. Exposed bedrock at both of the new sites erodes more slowly than the maximum soil production rates, at 22+ or -3 and 9+ or -2 m/m.y., respectively, thus suggesting a "humped" soil production function. We suggest that instead of a humped function, lithologic variations set the emergence of bedrock, which evolves into the tors that are found extensively across the highlands and at the crest of the escarpment by eroding more slowly than the surrounding soil-mantled landscape. Compared to soil production rates from previous work using (super 10) Be and (super 26) Al measurements from two different sites, these results show remarkable agreement and specifically quantify a soil production function for the region where soil production rates decline exponentially with increasing soil thickness, with an intercept of 53 m/m.y. and a slope of -0.02. Erosion rates determined from (super 10) Be concentrations from outcropping tors, bedrock, and saprolite from a main spur ridge perpendicular to the escarpment, and sediments from first- and zero-order catchments draining the main ridges, show a clear linear decline with elevation, from approximately 35 m/m.y. near the escarpment base to approximately 3 m/m.y. at the escarpment crest. This order of magnitude difference in erosion rates may be due to the increases in stream incision with distance downslope on the escarpment, or to decreases in precipitation with elevation, neither of which we quantify here. The rates do agree, in general, with our soil production functions, suggesting that the biogenic processes actively eroding soil-mantled landscapes are shaping the evolution of the escarpment despite our observations of block fall and debris-flow processes across the steep regions near the scarp crest. Our results support recent results from studies using low-temperature thermochronology, which suggest that the escarpment is relatively stable after having retreated rapidly immediately following rifting. Differences between our rates of surface erosion caused by processes active today and the scarp retreat rates needed to place the escarpment in its present position need to be explained by future work to untangle the mysteries of escarpment evolution.

Results obtained on samples collected in the Gulf of Alaska in the summer of 2002 provide a direct comparison with results in the 1970s during GEOSECS and in the early 1990s during WOCE. The open gyre values are 20-40 per mil lower than those documented in 1991 and 1993 (WOCE), although the general trends as a function of latitude are reproduced. Surface values are still significantly higher than pre-bomb levels ( approximately -105 per mil or lower). In the central gyre, we observe Delta (super 14) C values that are lower in comparison to GEOSECS (stn 218) and WOCE P16/P17 to a density of approximately 26.8 sigma (sub t) ?. This observation is consistent with the overall decrease in surface Delta (super 14) C values and reflects the erosion of the bomb- (super 14) C transient. We propose that erosion of the bomb- (super 14) C transient is accomplished by entrainment of low- (super 14) C water via vertical exchange within the Gulf of Alaska and replenishment of surface and subthermocline waters with waters derived from the far northwest Pacific.

This permits capture of cosmic dust in space where the high speeds usually result in destructive impact events. The performance of aerogel in laboratory impact tests is described. Completely intact capture is rare; most studies show that between 10% to 100% of the incident particle's mass is captured. However, in all cases unaltered domains were found in the particles captured in the laboratory at speeds up to 6 or 7 km s (super -1) . Several analytic techniques can be applied in situ to particles captured in aerogel, yielding data on the preimpact composition of the particle. Extraction techniques for removing small particles from aerogel are described, and after extraction, handling and analysis in the laboratory can proceed as for any small-sized particle. Coupled with the survival of intact regions in the captured particles, this allows detailed identification of the composition of the dust. Examples are given of current space missions using aerogel dust collectors: Data on these will soon be supplemented by cometary dust particles captured in aerogel on the NASA Stardust spacecraft.

The measured ratio of the diffusion coefficients for Li and K in water (D (sub Li) /D (sub K) = 0.6) is in good agreement with published data, providing evidence that the experimental design being used resolves the relative mobility of ions with adequate precision to also be used for determining the fractionation of isotopes by diffusion in water. In the case of Li, we found measurable isotopic fractionation associated with the diffusion of dissolved LiCl (D (super 7) (sub Li) /D (super 6) (sub Li) = 0.99772+ or -0.00026). This difference in the diffusion coefficient of (super 7) Li compared to (super 6) Li is significantly less than that reported in an earlier study, a difference we attribute to the fact that in the earlier study Li diffused through a membrane separating the water reservoirs. Our experiments involving Mg diffusing in water found no measurable isotopic fractionation (D (super 25) (sub Mg) /D (super 24) (sub Mg) = 1.00003+ or -0.00006). Cl isotopes were fractionated during diffusion in water (D (super 37) (sub Cl) /D (super 35) (sub Cl) = 0.99857+ or -0.00080) whether or not the co-diffuser (Li or Mg) was isotopically fractionated. The isotopic fractionation associated with the diffusion of ions in water is much smaller than values we found previously for the isotopic fractionation of Li and Ca isotopes by diffusion in molten silicate liquids. A major distinction between water and silicate liquids is that water surrounds dissolved ions with hydration shells, which very likely play an important but still poorly understood role in limiting the isotopic fractionation associated with diffusion.

The reactive transport model includes a solid-solution formulation to enable the use of the (super 234) U/ (super 238) U activity ratios in the solid and fluid as a tracer of mineral dissolution. The isotopic profiles are combined with profiles of the major element chemistry (especially alkalinity and calcium) to determine whether the apparent discrepancy between laboratory and field dissolution rates still exists when a mechanistic reactive transport model is used to interpret rates in a natural system. A suite of reactions, including sulfate reduction and methane production, anaerobic methane oxidation, CaCO (sub 3) precipitation, dissolution of plagioclase, and precipitation of secondary clay minerals, along with diffusive transport and fluid and solid burial, control the pore fluid chemistry in Site 984 sediments. The surface area of plagioclase in intimate contact with the pore fluid is estimated to be 6.9 m (super 2) /g based on both grain geometry and on the depletion of (super 234) U/ (super 238) U in the sediment via alpha -recoil loss. Various rate laws for plagioclase dissolution are considered in the modeling, including those based on (1) a linear transition state theory (TST) model, (2) a nonlinear dependence on the undersaturation of the pore water with respect to plagioclase, and (3) the effect of inhibition by dissolved aluminum. The major element and isotopic methods predict similar dissolution rate constants if additional lowering of the pore water (super 234) U/ (super 238) U activity ratio is attributed to isotopic exchange via recrystallization of marine calcite, which makes up about 10-20% of the Site 984 sediment. The calculated dissolution rate for plagioclase corresponds to a rate constant that is about 10 (super 2) to 10 (super 5) times smaller than the laboratory-measured value, with the value depending primarily on the deviation from equilibrium. The reactive transport simulations demonstrate that the degree of undersaturation of the pore fluid with respect to plagioclase depends strongly on the rate of authigenic clay precipitation and the solubility of the clay minerals. The observed discrepancy is greatest for the linear TST model (10 (super 5) ), less substantial with the Al-inhibition formulation (10 (super 3) ), and decreases further if the clay minerals precipitate more slowly or as highly soluble precursor minerals (10 (super 2) ). However, even several orders of magnitude variation in either the clay solubility or clay precipitation rates cannot completely account for the entire discrepancy while still matching pore water aluminum and silica data, indicating that the mineral dissolution rate conundrum must be attributed in large part to the gradual loss of reactive sites on silicate surfaces with time. The results imply that methods of mineral surface characterization that provide direct measurements of the bulk surface reactivity are necessary to accurately predict natural dissolution rates.

Geophysicists are divided in their views on the nature of this response, advocating either (1) homogeneously distributed deformation with the lithosphere deforming as a fluid continuum or (2) highly localized deformation with the lithosphere deforming as a system of blocks. The resolution of this issue has broad implications for understanding the tectonic response of continental lithosphere in general. Homogeneous deformation is supported by relatively low decadal, geodetic slip-rate estimates for the Altyn Tagh and Karakorum faults. Localized deformation is supported by high millennial, geomorphic slip rates constrained by both cosmogenic and radiocarbon dating on these faults. Based upon the agreement of rates determined by radiocarbon and cosmogenic dating, the overall linearity of offset versus age correlations, and the plateau-wide correlation of landscape evolution and climate history, the disparity between geomorphic and geodetic slip-rate determinations is unlikely to be due to the effects of surface erosion on the cosmogenic age determinations. Similarly, based upon the consistency of slip rates over various observation intervals, secular variations in slip rate appear to persist no longer than 2000 yr and are unlikely to provide reconciliation. Conversely, geodetic and geomorphic slip-rate estimates on the Kunlun fault, which does not have significant splays or associated thrust faults, are in good agreement, indicating that there is no fundamental reason why these complementary geodetic and geomorphic methods should disagree. Similarly, the geodetic and geomorphic estimates of shortening rates across the northeastern edge of the plateau area in reasonable agreement, and the geomorphic rates on individual thrust faults demonstrate a significant eastward decrease in the shortening rate. This rate decrease is consistent with the transfer of slip from the Altyn Tagh fault to genetically related thrust mountain building at its terminus. Rates on the Altyn Tagh fault suggest a similar decrease in rate, but the current data set is too small to be definitive. Overall, the high, late Pleistocene-Holocene geomorphic slip velocities on the major strike-slip faults of Tibet suggest that these faults absorb as much of India's convergence relative to Siberia as the Himalayan Main Frontal Thrust on the southern edge of the plateau.

The simulations were then analysed and the evaluation criteria computed to compare the models' performance for the gauged and ungauged modes using six criteria describing the model's performance in both high and low flow conditions. The comparisons were undertaken for all three participation levels (i.e. 3, 12 and 40 catchments). The results indicate that on the 3-catchment level model ranking may vary according to the tested criterion and catchment. Hence a larger number of catchments are necessary to evaluate the models' performance. Among the 10 models tested on the 12 and 40 catchment samples in gauged mode, GR5H, Mordor and SAC-SMA rank as the top three models. When analysing model results in the ungauged mode, SAC-SMA ranks as the best of the four tested models. The analysis of the submitted files highlights the need for continuing efforts to develop model parameterization strategies for ungauged catchments in order to improve prediction in ungauged basins (PUB).

The MOPEX science strategy involves: database creation, a priori parameter estimation methodology development, parameter refinement or calibration, and the demonstration of parameter transferability. A comprehensive MOPEX database has been developed that contains historical hydrometeorological data and land surface characteristics data for many hydrological basins in the United States (US) and in other countries. This database is being continuously expanded to include basins from various hydroclimatic regimes throughout the world. MOPEX research has largely been driven by a series of international workshops that have brought interested hydrologists and land surface modellers together to exchange knowledge and experience in developing and applying parameter estimation techniques. With its focus on parameter estimation, MOPEX plays an important role in the international context of other initiatives such as GEWEX, HEPEX, PUB and PILPS. This paper outlines the MOPEX initiative, discusses its role in the scientific community, and briefly states future directions.

Improved methods for parameter estimation (especially for parameters important to runoff response) are needed and require data from a wide range of climate regimes throughout the world. Accordingly, the GEWEX Hydrometeorology Panel (GHP) endorsed the concept of an international Model Parameter Estimation Project (MOPEX) at its Toronto meeting, August 1996. Phase I of MOPEX was funded by NOAA in financial year (FY) 1997, Phase II in FY 2000 and Phase III in FY 2003. MOPEX was adopted as a project of the IAHS/WMO Working Group on GEWEX and of the WMO Commission on Hydrology (CHy), and is now a contributor to the Combined Enhanced Observing Period (CEOP) of the World Climate Research Program (WCRP). In 2004, MOPEX became a Working Group of the IAHS Prediction in Ungauged Basins (PUB) Initiative. MOPEX is also expected to contribute to the work of the Hydrologic Ensemble Prediction Experiment (HEPEX). The primary goal of MOPEX is to develop techniques for the a priori estimation of the parameters used in land surface parameterization schemes of atmospheric models and in hydrological models. A major early effort of MOPEX has been to assemble a large number of high-quality historical hydrometeorological and river basin characteristics data sets for a wide range of river basins (500-10 000 Km (super 2) ) throughout the world. MOPEX data sets are available via the Internet (ftp://hydrology.nws.noaa.gov/pub/gcip/mopex/US_Data/). This paper documents the development of data sets for river basins in the USA. Several highly successful parameter estimation workshops have been organized by MOPEX. The first was held as part of the IAHS General Assembly in Birmingham, UK, in July 1999. The second workshop was hosted in April 2002 in Tucson, Arizona, USA, by the SAHRA/University of Arizona. The third MOPEX workshop was held as part of the IAHS General Assembly in Sapporo, Japan, July 2003. The fourth, in Paris, France, July 2005 was organized by the CEMAGREF in collaboration with the ENGREF, Meteo France, National Weather Service and the SAHRA/University of Arizona. The fifth workshop was held as part of the IAHS Scientific Assembly, February 2005, Foz do Iguacu, Brazil. The purpose of the future phases of the project is to: (a) continue collecting additional international data sets; update data from the USA by adding recent years, including data for elevation zones in mountainous areas and refining energy forcing data; (b) continue to conduct international MOPEX workshops; (c) provide leadership to develop a better scientific understanding of how to improve procedures for a priori parameter estimation; (d) make a significant hydrological contribution to CEOP and PUB; and (e) demonstrate transferability of MOPEX results. The basic data collection strategy being used in MOPEX is to seek the most readily available and highest quality data first. During the next three years, analyses of the available MOPEX data sets by the international scientific community will be emphasized.

The results show the Hector Mine sequence exhibits non-self-similar scaling with apparent stress increasing with moment approximately as M (sub o) (super 0.14.) Finally we briefly present four general scaling models, one self-similar with high variance, the others non-self-similar, which appear to be consistent with the earthquake apparent stress behavior that has been observed to date.

Recent studies show that the melting curve of H (sub 2) O increases rapidly above a recently discovered triple point at approximately 35 to 47 GPa and 1000 K, indicating a large increase in Delta V/Delta S (volume versus entropy change) and associated changes in the physical properties of H (sub 2) O at high pressures and temperatures. Existence of the triple point is thought to be associated with the formation of a superionic phase, dynamically-disordered ice VII, or extension of the ice VII-ice X phase boundary; although the precise pressure and temperature of the triple point, curvature of the melting line, and nature of the solid-solid transition below the triple point all remain to be further explored. The steep increase in the melting curve of H (sub 2) O at high pressures and temperatures has important implications on our understanding of planetary interiors. Depending on its curvature, the melting line of H (sub 2) O may intersect the isentropes of Neptune and Uranus as well as the geotherm of Earth's lower mantle.

Detailed comparison of the calc-silicate (zeolites and prehnite) mineral distributions with those from other regions indicates that this sequence exhibits consistently longer down-hole intervals for secondary species than reported elsewhere. The Lopra-1/1A mineral succession formed under conditions typical of low-temperature hydrothermal systems that form shortly after the euption of thick basaltic piles. The maximum temperatures achieved at the 3500 m level were at or below 200 degrees C; the implied geothermal gradient was less than 50 degrees C/km. An analysis of prehnite--fluid composition relationships indicated limiting the temperature for prehnite formation in equilibrium with an albite-quartz-calcite-laumontite assemblage to the range 140-205 degrees C.

The pelitic and metavolcanic schists and paragneisses are all highly deformed, while the orthogneisses appear more variably deformed, with increasing deformation evident towards the supracrustal units. The c. 1.92 Ga Arfersiorfik quartz diorite is traceable for a distance of at least 35 km from the Inland Ice towards the west-south-west. Towards its northern contact with an intensely deformed schist unit it shows a similar pattern of increasing strain, which is accompanied by chemical and mineralogical changes. The metasomatic changes associated with the shear zone deformation are superimposed on a wide range of original chemical compositions, which reflect magmatic olivine and/or pyroxene as well as hornblende fractionation trends. The chemistry of the Arfersiorfik quartz diorite suite as a whole is comparable to that of Phanerozoic plutonic and volcanic rocks of calc-alkaline affinity.

We present predictions of diamond and BC8 melting lines and their phase boundary in the solid phase, as obtained from first-principles calculations. Maxima are found in both melting lines, with a triple point located at nearly equal 850 GPa and nearly equal 7,400 K. Our results show that hot, compressed diamond is a semiconductor that undergoes metalization upon melting. In contrast, in the stability range of BC8, an insulator to metal transition is likely to occur in the solid phase. Close to the diamond/liquid and BC8/liquid boundaries, molten carbon is a low-coordinated metal retaining some covalent character in its bonding up to extreme pressures. Our results provide constraints on the carbon equation of state, which is of critical importance for devising models of Neptune, Uranus, and white dwarf stars, as well as of extrasolar carbon-rich planets.

Seventeen exploration wells, followed by four appraisal wells established these slope channel complexes as a world-class development opportunity. ExxonMobil's current development activity targets stacked turbidite-dominated reservoirs in long-reach, high-angle wellbores tied back to Tension Leg Platform (TLP) and close-moored FPSO facilities. One of the major development targets in Block 15 is Burdigalian-aged (Bur1) slope channel reservoirs. This slope channel system traverses across the block in an east-west direction and can be continuously mapped on adjacent seismic datasets over a 30-40 km reach. Map patterns of the Bur1 system show distinctive changes in sinuosity, channel confinement and degree of amalgamation broadly related to concurrent growth of salt-related structures. Channel complex confinement is more pronounced and lateral amalgamation better developed in segments that cross structural highs. The Bur1 channel system shows higher sinuosity, weaker lateral amalgamation and less erosional confinement in synclinal lows. The episodic fill of the Bur1 slope channel system can be better understood by a hierarchical arrangement of unconformity-bounded stratal units. Within these unconformity-bounded channel sets, nested channels form composite channel complexes that show distinctive trends in lithofacies type and vertical facies succession. Conventional cores calibrated to well-logs and high-resolution seismic data show the lower portions of the channel complexes are dominated by sandy-muddy debrites, slumps and injected sandstones. These facies are typically overlain by coarse-grained, gravelly and well-amalgamated sandy turbidites. The overlying facies succession is more variable, but commonly consists of interbedded sandy and muddy turbidites, injected sandstones, and a range of both muddy and sandy debrites.

To provide an integrative, easy-to-use and automated toolkit for the analysis of Affymetrix microarray expression data we have developed Array2BIO, an application that couples several analytical methods into a single web based utility. Results Array2BIO converts raw intensities into probe expression values, automatically maps those to genes, and subsequently identifies groups of co-expressed genes using two complementary approaches: (1) comparative analysis of signal versus control and (2) clustering analysis of gene expression across different conditions. The identified genes are assigned to functional categories based on Gene Ontology classification and KEGG protein interaction pathways. Array2BIO reliably handles low-expressor genes and provides a set of statistical methods for quantifying expression levels, including Benjamini-Hochberg and Bonferroni multiple testing corrections. An automated interface with the ECR Browser provides evolutionary conservation analysis for the identified gene loci while the interconnection with Creme allows prediction of gene regulatory elements that underlie observed expression patterns. Conclusion We have developed Array2BIO - a web based tool for rapid comprehensive analysis of Affymetrix microarray expression data, which also allows users to link expression data to Dcode.org comparative genomics tools and integrates a system for translating co-expression data into mechanisms of gene co-regulation.

The reproducibility of the microjet printing process is excellent for microdot (i.e. micrometer-sized polymer) sensor diameter (92.2 +/- 2.2 mu m), height (35.0 +/- 1.0 mu m), and roundness (0.00072 +/- 0.00023). pH sensors were evaluated in terms of pH sensing ability (<=2% sensor variation), response time, and hysteresis using a custom fluorescence imaging system. In addition, the microjet technique has distinct advantages over other fabrication methods, which are discussed in detail.

The key for the success of all these applications relies on the immobilization technique employed to attach the protein to the corresponding surface. Protein immobilization can be based on covalent or noncovalent interaction of the molecule with the surface. Noncovalent interactions include hydrophobic interactions, hydrogen bonding, van der Waals forces, electrostatic forces, or physical adsorption. However, since these interactions are weak, the molecules can get denatured or dislodged, thus causing loss of signal. They also result in random attachment of the protein to the surface. Site-specific covalent attachment of proteins onto surfaces, on the other hand, leads to molecules being arranged in a definite, orderly fashion and uses spacers and linkers to help minimize steric hindrances between the protein and the surface. This work reviews in detail some of the methods most commonly used as well as the latest developments for the site-specific covalent attachment of protein to solid surfaces.

MNPs were conjugated with luteinizing hormone releasing hormone (LHRH), whose receptors are expressed by most types of breast cancer cells. After the nanoparticles were injected into female nude mice bearing MDA-MB-435S.luc tumors, the mice were sacrificed to collect tumors and peripheral organs for biological and TEM analyses. LHRH conjugated SPIONs (LHRH- SPIONs) were found to accumulate in cancer cells, mainly in the primary tumors and the metastatic lungs, where they aggregated to form clusters. In contrast, most of the unconjugated SPIONs were collected in the liver cells. The results suggest that LHRH- SPIONs can be used to target cancer cells in the primary breast tumors and the lung metastases. TEM is also shown to be a useful tool for the studies of sub-cellular distributions of SPIONs in tumors and tissues.

Fundamental to the pursuit of effective investment strategies is an ability to quantify tradeoffs associated with potential policy and management changes. However, the data needed to predict regional yield responses to change, namely observations of yields and climatic, soil, and management conditions in farmers' fields, are often difficult to obtain. In this paper, we investigate the value of data on the spatial distribution of yields for understanding causes of landscape yield variability. Stochastic simulation models, which employ the CERES model to simulate crop yields across a landscape, are used to translate assumed spatial patterns of soil and management conditions into spatial pattern of yields. Monte Carlo simulation is then used to repeat this process for many different realizations of conditions, resulting in a modeled relationship between yield patterns and the relative importance of soil and management yield constraints, both of which can be computed in the controlled simulation environment. The derived relationship then allows one to infer from observed yield patterns the true proportion of yield variability explained by soil and management. This procedure was tested for wheat in the Yaqui Valley, an intensive agricultural region in Sonora, Mexico, where yield patterns have been previously estimated with remote sensing. Comparison of simulated and observed yield patterns indicated that roughly 80% of spatial yield variance in 2001-2002 was attributable to management variations. The ability of simulation models to aid interpretation of landscape patterns is potentially invaluable for understanding yield constraints in many agricultural regions, where direct observations of soil and management variables are infeasible.

The impact of millions of cubic meters of wastewater discharged to the vadose zone (10 super(3)- 10 super(5) times higher than ambient drainage) shows up strikingly on maps of groundwater super(87)Sr/ super(86)Sr. Extensive access through the many groundwater monitoring wells at the site allows for an unprecedented opportunity to evaluate the strontium geochemistry of a major aquifer, hosted primarily in unconsolidated sediments, and relate it to both long term properties and recent disturbances. Groundwater super(87)Sr/ super(86)Sr increases systematically from 0.707 to 0.712 from west to east across the Hanford Site, in the general direction of groundwater flow, as a result of addition of Sr from the weathering of aquifer sediments and from diffuse drainage through the Pasco Basin vadose zone. The lower super(87)Sr/ super(86)Sr groundwater reflects recharge waters that have acquired Sr from Columbia River Basalts. Based on a steady-state model of Sr reactive transport and drainage, there is an average natural drainage flux of 0-1.4 mm/yr near the western margin of the Hanford Site, and ambient drainage may be up to 30 mm/yr in the center of the site assuming an average bulk rock weathering rate of 10 super(-7.5) g/(g/yr). The weathering rates cannot be higher than those assumed by more than a factor of 2-3, in order to match Sr isotope data.

The experimental data obtained in single- sorbate experiments were modeled using a diffuse double layer surface complexation model and used to predict and compare sorption in dual-sorbate systems. The sorption process was shown to be reversible by the complete recovery of sorbed Fe(II) upon extraction with 0.5 N HCl. Sorption of Fe(II) increases with increasing pH, as observed previously for various iron oxides. Sorption isotherms obtained between pH 6.0 and 7.5 showed continuous increase in sorption density with increase in dissolved Fe(II) concentration; under these conditions, surface saturation was approached but not reached. Experiments conducted in the absence and presence of 500 and 1000 mu M total As(III) did not show any significant difference in the Fe(II) sorption density. As(III) sorption density did not change with increasing sorbed Fe(II) concentration when the total arsenic concentration was 500 mu M. However, when the total As(III) concentration was 1000 mu M, As(III) sorption densities increased almost linearly with increasing sorbed Fe(II) concentrations. The model provided a good-to- adequate description of Fe(II) and As(III) sorption in single-sorbate systems over a range of experimental conditions but failed to predict the experimental observations in dual-sorbate systems. The predicted sorption densities for both As(III) and Fe(II) were lower than those observed. These discrepancies illustrate problems that may arise when model parameters obtained in single- sorbate systems are used to predict sorption in multi-sorbate systems where all sorbates are presumed to compete for the same sites. The lack of competition observed between As(III) and Fe(II) for sorption sites indicate that the concurrent release of Fe(II) and As(III) during reductive dissolution of iron oxides, inferred as the mechanism of arsenic mobilization in many reducing ground waters, may have relatively minor effects on the subsequent re-sorption of As(III) to residual iron oxides remaining in the sediment.

The concentration levels of these radionuclides in the corals lie in the range 10 (super 4) to 10 (super 8) atoms/g. A comparison of the measured nuclide concentrations with those expected to be produced in the corals by nuclear interactions of energetic cosmic radiation shows that (i) the radionuclides (super 26) Al and (super 36) Cl are derived from in situ cosmic ray interactions in the corals after their formation, but that (ii) the radionuclide (super 10) Be owes its provenance in the coralline lattice primarily due to incorporation of dissolved beryllium in seawater in the lattice structure of the corals.

Although the potential benefits of longer chronologies are obvious, the greater uncertainty associated with older cosmogenic ages may be less readily apparent. We illustrate the challenges of developing and interpreting a long chronology using our data from the Peruvian Andes. We used surface exposure dating with cosmogenic radionuclides (CRNs; (super 10) Be and (super 26) Al) to date 140 boulders on moraines in valleys bordering the Junin Plain (11 degrees S, 76 degrees W) in central Peru. Our chronology spans multiple glacial cycles and includes exposure ages greater than 1 million years, which indicate that long-term rates of boulder erosion have been very low. Interpreting the chronology of moraines for glaciations that predate the last glacial cycle is complicated by the need to consider boulder erosion and exhumation, surface uplift, and inheritance of CRNs from previous exposure intervals. As an example, we recalculate exposure ages using our boulder erosion rates (0.3-0.5 metres per million years) and estimated surface uplift rates to emphasise both the challenges involved in interpreting old surface exposure ages and the value of chronological data, even with large uncertainties, when reconstructing the palaeoclimate of a region.

In order of decreasing age, these are the Cojup, Rurec and Laguna Baja moraines. The oldest moraines occur at the lowest elevations and yield dates of >400 ka pre-dating the last interglacial and demonstrating that maximum ice volumes occurred during previous glacial periods, and not at the end of the last glacial. Our new data from the younger moraines indicate that the end of the last glacial cycle comprised two separate advances at ca. 29 ka and ca. 16.5 ka, each reflecting significant (>4 degrees C) tropical of cooling at 10 degrees S. These data combined with published records from the Laurentide ice sheet, indicate that climate instabilities associated with the close of the last glacial were likely global and synchronous in nature.

The soil examined is a profile composed of a surface soil overlying four buried horizons that have all developed from successive tephra deposits. Non-destructive spectro-scopy (XRD, FTIR and NMR of Si and Al) showed that the mineralogical composition varies from one buried horizon to another. It is shown that buried horizons characterized by large amounts of crystalline minerals (feldspars, gibbsite) have the least capacity to store organic matter and the fastest carbon turnover. In contrast, buried horizons containing much poorly crystalline material (proto-imogolite and proto-imogolite allophane, denoted LP-ITM) store large amounts of organic matter that turns over very slowly. To understand the mechanism of interactions between LP-ITM and organic matter better, a horizon formed exclusively of LP-ITM was focused on. It is demonstrated using Delta (super 14) C and delta (super 13) C values, that even though LP-ITM is extraordinarily effective at stabilizing organic matter, C linked to LP-ITM is still in dynamic equilibrium with its environment and cycles slowly. Based on Delta (super 14) C values, the residence time of organic C is estimated as approximately 163 000 years for the most stabilized subhorizon, a value that is comparable to that for organic carbon stabilized in Hawaiian volcanic soils. This calculation is likely to be biased by the presence of microcharcoal. The results demonstrate the important role of poorly crystalline minerals in the storage of organic C, and show that mineral and organic compounds have to be studied simultaneously to understand the dynamics of organic C in the soil.

Although mass-wasting processes are common phenomena in supradetachment basins, the Shadow Valley basin is an exceptional locale for the study of such processes, especially rock-avalanches and gravity sliding. A score of megabreccias, interpreted as rock-avalanche deposits, and half that number of very large (>1 km (super 2) , up to 200 m thick), internally intact gravity-driven slide sheets are interbedded with various sedimentary facies. The slide sheets, variably composed of Proterozoic crystalline rocks and Proterozoic, Paleozoic, and Tertiary sedimentary strata, moved across both depositional and erosional surfaces in the basin. Although the majority consist of Paleozoic carbonate rocks, the largest slide sheet, the Eastern Star crystalline allochthon, contains Proterozoic gneisses and their sedimentary cover and is now preserved as klippen atop Miocene lacustrine and alluvial fan deposits over an area >40 km (super 2) . Estimates of slide sheet runouts into the basin from higher eastern and northern source terranes range from approximately a few km to >10 km; in most cases the exact provenances of the slide blocks are not known. The basal contacts of Shadow Valley slide sheets are characteristically knife sharp, show few signs of lithologic mixing of upper- and lower-plate rocks, and locally exhibit slickensided and striated, planar fault-like bases. Pronounced folding of overridden Miocene lacustrine and fan deposits beneath the Eastern Star allochthon extends to depths up to 40 m at widely scattered localities. We conclude that this slow moving slide sheet encountered isolated topographic asperities (hills) and that stress transfer across the basal slide surface produced folding of footwall strata. Synkinematic gypsum veins in footwall playa sediments, with fibers up to 12 cm long, have trends and shear senses compatible with the direction and sense of displacement of the overriding crystalline allochthon. The undisturbed veins, which closely parallel the base of the slide sheet, attest to high fluid presence and pressure in the playa sediments-factors facilitating allochthon movement across them. The long length of the fibers, indicative of a protracted dilational process, is incompatible with a catastrophic rate of emplacement. We believe that the only explanation for slow displacement of this allochthon and other gravity driven slide sheets across the landscape is that they formed as slumps on high, steep bedrock slopes and that their elevated heads drove their toes across lower fan and playa deposits. Initial detachments from bedrock sources were facilitated by pre-existing structural and stratigraphic anisotropies. Detachment of the Eastern Star allochthon from the bedrock of Shadow Mountain likely occurred by inversion along the playa-ward dip of a preexisting Mesozoic thrust fault within Proterozoic rock units.

Here we present the genome of B. abortus 2308, the virulent prototype biovar 1 strain, and its comparison to the two other human pathogenic Brucella species and to B. abortus field isolate 9-941. The global distribution of pseudogenes, deletions, and insertions supports previous indications that B. abortus and B. melitensis share a common ancestor that diverged from B. suis. With the exception of a dozen genes, the genetic complements of both B. abortus strains are identical, whereas the three species differ in gene content and pseudogenes. The pattern of species-specific gene inactivations affecting transcriptional regulators and outer membrane proteins suggests that these inactivations may play an important role in the establishment of host specificity and may have been a primary driver of speciation in the genus BRUCELLA: Despite being nonmotile, the brucellae contain flagellum gene clusters and display species-specific flagellar gene inactivations, which lead to the putative generation of different versions of flagellum-derived structures and may contribute to differences in host specificity and virulence. Metabolic changes such as the lack of complete metabolic pathways for the synthesis of numerous compounds (e.g., glycogen, biotin, NAD, and choline) are consistent with adaptation of brucellae to an intracellular life-style.

It is not clear which effect would dominate. We have performed simulations of global land cover change using the NCAR CAM3 atmospheric general circulation model coupled to a slab ocean model. We find that global replacement of current vegetation by trees would lead to a global mean warming of 1.3 degree C, nearly 60% of the warming produced under a doubled CO sub(2) concentration, while replacement by grasslands would result in a cooling of 0.4 degree C. It has been previously shown that boreal forestation can lead to warming; our simulations indicate that mid- latitude forestation also could lead to warming. These results suggest that more research is necessary before forest carbon storage should be deployed as a mitigation strategy for global warming.

This allows the estimation of SSC directly from the NMR spectrum without the time intensive process of chemical shift assignment. Here, we present an empirical correlation that accounts both for contributions to the relevant protein and chemical shift databases made subsequent to the original analysis, and for missing or inconsistently referenced resonances. Our results affirm that this method provides a significant tool for initial structural prediction from NMR data prior to complete chemical shift assignment.

Current modeling approaches, such as constraint-based flux-balance analysis, have proved highly successful in analyzing the capabilities of cellular metabolism, including its capacity to predict deletion phenotypes, the ability to calculate the relative flux values of metabolic reactions, and the capability to identify properties of optimal growth states. Here, we use flux- balance analysis to thoroughly assess the activity of Escherichia coli, Helicobacter pylori, and Saccharomyces cerevisiae metabolism in 30,000 diverse simulated environments. We identify a set of metabolic reactions forming a connected metabolic core that carry non-zero fluxes under all growth conditions, and whose flux variations are highly correlated. Furthermore, we find that the enzymes catalyzing the core reactions display a considerably higher fraction of phenotypic essentiality and evolutionary conservation than those catalyzing noncore reactions. Cellular metabolism is characterized by a large number of species-specific conditionally active reactions organized around an evolutionary conserved, but always active, metabolic core. Finally, we find that most current antibiotics interfering with bacterial metabolism target the core enzymes, indicating that our findings may have important implications for antimicrobial drug-target discovery.

Over 4,100 individual protein spots were detected, of which hundreds were differentially expressed. A total of 43 differentially expressed protein spots, representing 24 unique proteins, were identified by mass spectrometry. Differences in expression were observed for several virulence-associated factors, including catalase-peroxidase (KatY), murine toxin (Ymt), plasminogen activator (Pla), and F1 capsule antigen (Caf1), as well as several putative virulence factors and membrane-bound and metabolic proteins. Differentially expressed proteins not previously reported to contribute to virulence are candidates for more detailed mechanistic studies, representing potential new virulence determinants.

Carbon and hydrogen isotope ratios of benzene were between -25.9 ppm and -26.8 ppm for delta (super 13) C and -119 ppm and -136 ppm for delta (super 2) H, suggesting that biodegradation of benzene is unlikely at this site. However, biodegradation of both xylenes and toluene were documented in this subarctic aquifer. Biodegradation of xylenes was indicated by the presence of methylbenzylsuccinates with concentrations of 17-50 mu g/L in three wells. Anaerobic toluene biodegradation was also indicated by benzylsuccinate concentrations of 10-49 mu g/L in the three wells with the highest toluene concentrations (1500-5000 mu g/L toluene). Since benzylsuccinate typically accounts for a very small fraction of the toluene present in groundwater (generally <1 mol%), the signature metabolite approach works best at higher toluene concentrations when it is not constrained by detection limits. In wells with lower toluene concentrations (410-640 mu g/L), carbon and hydrogen isotopic values were enriched by up to approximately 2 ppm for delta (super 13) C and approximately 70 ppm for delta (super 2) H. This evidence of isotopic fractionation verifies the effects of biodegradation in these low concentration wells where metabolites may already be below detection limits. The combined use of signature metabolite and CSIA data is particularly valuable given the challenge of verifying biodegradation in subarctic environments where degradation rates are typically much slower than in temperate environments.

However unlike corals, they do not have density variations, making age determination difficult. In this study, we examined multiple elemental ratios (B/Ca, Mg/Ca, Sr/Ca, Ba/Ca, U/Ca) in the coralline sponge Astrosclera willeyana. We also measured skeletal density profiles along the outer "living" edge of the sponges and these data indicate significant thickening of skeletal material over intervals of 2-3 mm which corresponds to 2-3 years. This suggests that any skeletal recovered environmental record from A. willeyana is an integration of signals over a similar to 2-3 year period. Sponge Sr/Ca seemed to hold the most promise as a recorder of water temperature and we compared Sr /Ca from 2 sponges in the Great Barrier Reef and one from Truk in Micronesia to their respective sea surface temperature record. The correlations were not strong ( rho =-0.5) but were significant. It appears that the signal smoothing due to thickening or perhaps even some other control (biologic, biomineralization) on Sr skeletal partitioning limits the use of Sr/Ca as an indicator of water temperature in A. willeyana. Variations of B/Ca, Mg/Ca, Ba/Ca and U /Ca only have moderate to poor correlations to Sr/Ca and are not consistent between samples. They also do not show correlations with water temperature and may be more heavily influenced by the biomineralization occurring in the secondary thickening.

Mass spectra of individual Bacillus endospores were measured with a bipolar aerosol time-of-flight mass spectrometer in which molecular desorption and ionization were produced using a single laser pulse from a Q-switched, frequency-quadrupled Nd:YAG laser that was modified to have an approximately flattop profile. The flattened laser profile allowed the minimum fluence required to desorb and ionize significant numbers of ions from single aerosol particles to be determined. For Bacillus spores, this threshold had a mean value of similar to 1 nJ/ mu m super(2) (0.1 J/cm super(2)). Thresholds for individual spores, however, could apparently deviate by 20% or more from the mean. Threshold distributions for clumps of MS2 bacteriophage and bovine serum albumin were subsequently determined. Finally, the flattened profile was observed to increase the reproducibility of single-spore mass spectra. This is consistent with the general conclusions of our earlier paper on the fluence dependence of single-spore mass spectra and is particularly significant because it is expected to enable more robust differentiation and identification of single bioaerosol particles.

AN - 68715065; 15944213 AB - UDP-glucuronosyltransferases (UGTs) catalyze the glucuronidation of many different chemicals. Glucuronidation is especially important for detoxifying reactive intermediates from metabolic reactions, which otherwise can be biotransformed into highly reactive cytotoxic or carcinogenic species. Detoxification of certain food-borne-carcinogenic heterocyclic amines (HAs) is highly dependent on UGT1A-mediated glucuronidation. 2-Amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP), the most mass abundant carcinogenic HA found in well-done cooked meat, is extensively glucuronidated by UGT1A proteins. In humans, CYP1A2 catalyzed N-hydroxylation and subsequent UGT1A-mediated glucuronidation is a dominant pathway in the metabolism of PhIP. Therefore, changes in glucuronidation rates could significantly alter PhIP metabolism. To determine the importance of UGT1A-mediated glucuronidation in the biotransformation of PhIP, hepatic UGT1A deficient Gunn and UGT1A proficient Wistar rats were exposed to a 100 microg/kg oral dose of [(14)C]PhIP. Urine was collected over 24 h and the PhIP urinary metabolite profiles were compared between the two strains. After the 24 h exposure, livers and colons were removed and analyzed for DNA adduct formation by accelerator mass spectrometry. Wistar rats produced several PhIP and N-hydroxy-PhIP glucuronides that accounted for approximately 25% of the total amount of recovered urinary metabolites. In the Gunn rats, PhIP and N-hydroxy-PhIP glucuronides were reduced by 68-92%, compared with the Wistar rats. PhIP-DNA adduct analysis from the Gunn rats revealed a correlation between reduced urinary PhIP and N-hydroxy-PhIP glucuronide levels and increased hepatic DNA adducts, compared with the Wistar rats. In the colon, DNA adduct levels were lower in the Gunn rats compared with the Wistar rats, suggesting deficient hepatic UGT1A activity provides protection against DNA adduct formation in peripheral tissue. Due to differences in PhIP metabolism between humans and rodents, extrapolation of these results to the human situation must be done with caution. These results indicate that UGT1A-mediated glucuronidation of PhIP and N-hydroxy-PhIP is an important pathway for PhIP detoxification, and demonstrate the importance of tissue-specific metabolism. Tissues with reduced UGT1A activity can have a higher rate of PhIP activation and be more inclined to form DNA adducts compared with tissues with normal UGT1A activity.

In order to analyze this question, we consider two countries and assume that publicly-owned firms are less efficient than private firms. We obtain that when the marginal cost of the publicly-owned firms takes an intermediate value, each government wants it to be the government of the other country that privatizes its publicly-owned firm. In this case, only one government privatizes, and that government obtains lower social welfare and producer surplus than the other. References. Adapted from the source document.

AN - 59743318; 200703503 AB - This paper compares, in a polluting oligopoly, an emission tax and a form of environmental policy called voluntary agreement (VA). Here there are two ways of reducing pollution: output contraction and end-of-pipe abatement. Given the imperfect competition, firms' reaction to the tax is sub-optimal. They reduce output excessively in order to raise the price and do not abate enough. The VA is a take-it-or-leave-it contract on abatement effort, offered to the firms with the threat of a tax. It has a limited effect on output and always allows higher abatement than the tax. We find that this kind of VA may be more efficient than the tax in a concentrated industry, when pollution is not too harmful and when the abatement technology is rather efficient and cheap.

One of these tests has been used to study the hydrological transport of radionuclides for over 25 years in groundwater and the deep unsaturated zone. Ten years after the weapon's test, a 16 year groundwater pumping experiment was initiated to study the mobility of radionuclides from that test in an alluvial aquifer. The continuously pumped groundwater was released into an unlined ditch where some of the water infiltrated into the 200 m deep vadose zone. The pumped groundwater had well-characterized tritium activities that were utilized to trace water migration in the shallow and deep vadose zones. Within the near-surface vadose zone, tritium levels in the soil water are modelled by a simple one-dimensional, analytical wetting front model. In the case of the near-surface soils at the Cambric Ditch experimental site, water flow and salt accumulation appear to be dominated by rooted vegetation, a mechanism not included within the wetting front model. Simulation results from a two-dimensional vadose groundwater flow model illustrate the dominance of vertical flow in the vadose zone and the recharge of the aquifer with the pumped groundwater. The long-time series of hydrological data provides opportunities to understand contaminant transport processes better in the vadose zone with an appropriate level of modelling.

Aerogel, a proven capture medium, is also a candidate for future sample return missions and low-Earth orbit (LEO) deployments. Critical to the science return of Stardust as well as future missions that will use aerogel is the ability to efficiently extract impacted particles from collector tiles. Researchers will be eager to obtain Stardust samples as quickly as possible; tools for the rapid extraction of particle impact tracks that require little construction, training, or investment would be an attractive asset. To this end, we have experimented with diamond and steel microblades. Applying ultrasonic frequency oscillations to these microblades via a piezo-driven holder produces rapid, clean cuts in the aerogel with minimal damage to the surrounding collector tile. With this approach, intact impact tracks and associated particles in aerogel fragments with low-roughness cut surfaces have been extracted from aerogel tiles flown on NASA's Orbital Debris Collector (ODC) experiment. The smooth surfaces produced during cutting reduce imaging artifacts during analysis by scanning electron microscopy (SEM). Some tracks have been dissected to expose the main cavity for eventual isolation of individual impact debris particles and further analysis using techniques such as transmission electron microscopy (TEM) and nano-secondary ion mass spectrometry (nanoSIMS).

This binding interaction is central to the design of molecules used for targeted delivery of radioimmunotherapeutic agents for prostate and breast cancer treatment. Our experiments separated the specific binding interaction from nonspecific interactions by tethering the antibody and MUC1 molecules to the atomic force microscope tip and sample surface with flexible polymer spacers. Rupture force magnitude and elastic characteristics of the spacers allowed identification of the rupture events corresponding to different numbers of interacting proteins. We used dynamic force spectroscopy to estimate the intermolecular potential widths and equivalent thermodynamic off rates for monovalent, bivalent, and trivalent interactions. Measured interaction potential parameters agree with the results of molecular docking simulation. Our results demonstrate that an increase of the interaction valency leads to a precipitous decline in the dissociation rate. Binding forces measured for monovalent and multivalent interactions match the predictions of a Markovian model for the strength of multiple uncorrelated bonds in a parallel configuration. Our approach is promising for comparison of the specific effects of molecular modifications as well as for determination of the best configuration of antibody-based multivalent targeting agents.

The mechanism for this specificity has not been fully elucidated and is usually attributed to differences in organ metabolism. For heterocyclic amines, potent carcinogens that are formed in well-done meat, the ability to either bind to the estrogen receptor and activate or inhibit an estrogenic response will have a major impact on carcinogenicity. Here, we describe our work with the human estrogen receptor alpha (ER alpha ), the mutagenic/carcinogenic heterocyclic amines PhIP, MeIQx, and IFP, and the hydroxylated metabolite of PhIP, N super(2)-hydroxy-PhIP. We demonstrate both by computational docking and NMR analysis that PhIP binds with the ligand binding domain (LBD). This binding competes with estradiol (E2) in the native E2 binding cavity of the receptor. In vitro assays show that PhIP, in contrast to the other heterocyclic amines, increases cell proliferation in MCF-7 human breast cancer cells and activates the ER alpha receptor. We also find that other heterocyclic amines and N super(2)-hydroxy-PhIP inhibit ER alpha activation. We propose that the mechanism for the tissue-specific carcinogenicity seen in the rat breast tumors and the presumptive human breast cancer associated with the consumption of well-done meat maybe mediated by this receptor activation.

They have an arborescent growth form with a skeletal axis composed of annual rings made from calcite and gorgonin. Lifespans may exceed several hundreds of years. It has been suggested that isotope profiles from the gorgonin fraction of the skeleton could be used to reconstruct long-term, annual-scale variations in surface productivity. We tested assumptions about the trophic level, intra- and inter-colony isotopic reproducibility, and preservation of isotopic signatures in a suite of modern and fossil specimens. Measurements of gorgonin delta (super 15) N indicate that Primnoa spp. feed mainly on zooplankton and/or sinking particulate organic matter (POM (sub sink) ), and not on suspended POM (POM (sub susp) ) or dissolved organic carbon (DOC). Gorgonin delta (super 13) C and delta (super 15) N in specimens from NE Pacific shelf waters, NW Atlantic slope waters, the Sea of Japan, and a South Pacific (Southern Ocean sector) seamount were strongly correlated with surface apparent oxygen utilization (AOU; the best available measure of surface productivity), demonstrating coupling between skeletal isotopic ratios and biophysical processes in surface water. Time-series isotopic profiles from different sections along the same colony, and different colonies inhabiting the same area were identical for delta (super 13) C, while delta (super 15) N profiles were less reproducible. Similarity in C:N, delta (super 13) C and delta (super 15) N between modern and fossil specimens suggest that isotopic signatures are preserved over millennial timescales. These results support the use of Primnoa spp. as historical recorders of surface water processes such as biological productivity and the isotopic composition of source nutrients. JF - Marine Ecology.

AN - 68820682; 16297216 AB - The Homeland Security Act mandates the development of a national, risk-based system to support planning for, response to, and recovery from emergency situations involving large-scale toxic exposures. To prepare for and manage consequences effectively, planners and responders need not only to identify zones of potentially elevated individual risk but also to predict expected casualties. Emergency response support systems now define "consequences" by mapping areas in which toxic chemical concentrations do or may exceed Acute Exposure Guideline Levels (AEGLs) or similar guidelines. However, because AEGLs do not estimate expected risks, current unqualified claims that such maps support consequence management are misleading. Intentionally protective, AEGLs incorporate various safety/uncertainty factors depending on the scope and quality of chemical-specific toxicity data. Some of these factors are irrelevant, and others need to be modified, whenever resource constraints or exposure-scenario complexities require responders to make critical trade-off (triage) decisions in order to minimize expected casualties. AEGL-exceedance zones cannot consistently be aggregated, compared, or used to calculate expected casualties and so may seriously misguide emergency response triage decisions. Methods and tools well established and readily available to support environmental health protection are not yet developed for chemically-related environmental health triage. Effective triage decisions involving chemical risks require a new assessment approach that focuses on best estimates of likely casualties, rather than on upper plausible bounds of individual risk. If risk-based consequence management is to become a reality, federal agencies tasked with supporting emergency response must actively coordinate to foster new methods that can support effective environmental health triage.

AN - 68753597; 16266157 AB - The development of time-reversal (T/R) communication systems is a recent signal processing research area dominated by applying T/R techniques to communicate in hostile environments. The fundamental concept is based on time-reversing the impulse response or Green's function characterizing the uncertain communications channel to mitigate deleterious dispersion and multipath effects. In this paper, we extend point-to-point to array-to-point communications by first establishing the basic theory to define and solve the underlying multichannel communications problem and then developing various realizations of the resulting T/R receivers. We show that not only do these receivers perform well in a hostile environment, but they also can be implemented with a "1 bit" analog-to-digital converter design structure. We validate these results by performing proof-of-principle acoustic communications experiments in air. It is shown that the resulting T/R receivers are capable of extracting the transmitted coded sequence from noisy microphone array measurements with zero-bit error.

AN - 68649835; 16204525 AB - Single-particle laser desorption/ionization time-of-flight mass spectrometry, in the form of bioaerosol mass spectrometry (BAMS), was evaluated as a rapid detector for individual airborne, micron-sized, Mycobacterium tuberculosis H37Ra particles, comprised of a single cell or a small number of clumped cells. The BAMS mass spectral signatures for aerosolized M. tuberculosis H37Ra particles were found to be distinct from M. smegmatis, Bacillus atrophaeus, and B. cereus particles, using a distinct biomarker. This is the first time a potentially unique biomarker was measured in M. tuberculosis H37Ra on a single-cell level. In addition, M. tuberculosis H37Ra and M. smegmatis were aerosolized into a bioaerosol chamber and were sampled and analyzed using BAMS, an aerodynamic particle sizer, a viable Anderson six-stage sampler, and filter cassette samplers that permitted direct counts of cells. In a background-free environment, BAMS was able to sample and detect M. tuberculosis H37Ra at airborne concentrations of >1 M. tuberculosis H37Ra-containing particles/liter of air in 20 min as determined by direct counts of filter cassette-sampled particles, and concentrations of >40 M. tuberculosis H37Ra CFU/liter of air in 1 min as determined by using viable Andersen six-stage samplers. This is a first step toward the development of a rapid, stand-alone airborne M. tuberculosis particle detector for the direct detection of M. tuberculosis bioaerosols generated by an infectious patient. Additional instrumental development is currently under way to make BAMS useful in realistic environmental and respiratory particle backgrounds expected in tuberculosis diagnostic scenarios.

As few lakes predate the local last glacial maximum (LLGM), CRN dates are important for the reconstruction of glacial activity early in the last glacial cycle. In contrast, as the moraine record of glaciation is fragmented and cannot record intervals of reduced ice extent, glacial lakes provide the continuity of record and increased precision in age control to augment CRN-based chronologies for the past approximately 20 ka. We have developed a chronology of glaciation for the the Junin Plain (4000 masl) of central Peru (11 degrees S; 76 degrees W). CRN dating indicates that moraines of the last glacial cycle stabilized during three intervals: 34-22, 20-16, and 15-12 ka (Smith et al., 2005, Science 308, 678+). Importantly, maximum ice volume in the tropical Andes occurred 30-34 ka, and ice retreat was underway by approximately 21 ka, which contrasts markedly with the record of global ice volume. The flux of clastic sediment to glacial lakes varies from 5500 masl show a pronounced increase in glacial flour flux that began approximately 5 ka, and reached maximum levels by approximately 2 ka. A composite record of glacial flour flux reveals the highest variance during the late glacial, which reflects the variable timing of deglaciation of lakes at various elevations. Likewise, high variance among records occurs during the late Holocene, when low elevation catchments remained ice-free and high-elevation catchments were reoccupied by ice. The lowest variance occurs during the early Holocene when lakes at all elevations reveal the lowest rates of glacial flour flux. This early Holocene interval of low flour flux corresponds with records of reduced hydrologic balance in the tropical Andes.

Although slip rates in the region are well constrained geodetically, there has been limited quantitative geochronology with which to compare the short-term geodetic rates to intermediate- and long-term geologic slip rates along the fault system. As a consequence, the northern Death Valley fault zone remains as the largest major missing piece to the geologic versus geodetic slip rate "puzzle" in the northern-half of the eastern California shear zone. We are using the accumulation of in-situ cosmogenic (super 10) Be measured in quartzite clasts and high-resolution (sub-meter) LiDAR digital topographic data to generate slip rates at a variety of time scales at several locations along the fault zone. Cosmogenic nuclide samples were collected from boulder-sized quartzite clasts on the dextrally-offset alluvial fans, such as the one at Red Wall Canyon, in central Death Valley. By restoring offset alluvial channels in LiDAR images to their original, pre-faulting positions, the amount of displacement during mid-Pleistocene to Holocene time can be resolved. Geologic slip rates based on the age and displacement of the offset surfaces will be presented. Comparison of these slip rates with geologic slip rates on other major faults (e.g. Owens Valley, Saline Valley-Hunter Mountain, Ash Hill, etc.) at similar latitudes will allow us to determine the constancy, or non-constancy, of strain release in the eastern California shear zone at a wide range of time scales. Determining a slip rate budget north of the Garlock Fault has implications for the occurrence and locations of strain transients along major plate boundaries, such as those suggested for the Mojave section of the eastern California shear zone. Once we know precise slip rates on all major faults we can identify whether transient strain accumulation is characteristic of the entire plate boundary or alternatively, the result of local complexities such as the Big Bend of the San Andreas Fault.

The longest of 4 vibracores from Gilligan Lake encountered a soil profile overlain by aquatic sediment at an elevation of approximately 182 meters above mean sea level. Radiocarbon dates indicate that aquatic deposition began during the Nipissing peak in Lake Michigan water levels. The bottom of a core from a somewhat deeper part of the lake contains aquatic sediments deposited at the same time at an elevation of 180 meters. Our single core from Kelly Lake indicates that aquatic sedimentation began about 1,000 years earlier at an elevation of approximately 175 meters. The basal units of all the cores consist of fine to medium grained sand with layering defined by variations in the amount of intermixed carbonaceous organics. The middle and upper units of the Gilligan Lake cores and the middle units of the Kelly Lake core are dominated by carbonaceous organics. A carbonate rich layer occurs near the base of the middle unit in the Kelly Lake core. The upper unit of the Kelly Lake core is predominantly fine silt and clay. Radiocarbon ages indicate that the transition from predominantly clastic inorganic sediments in the basal units to predominantly biological sediments in the middle units of the cores coincides with the early stages of the main phase in the growth and development of the adjacent dunes. The onset of sedimentation in these lakes is probably linked to the estuarine backflooding of westward flowing rivers during the rise in the Lake Michigan basin water levels from the Chippewa low to the Nipissing high. The growth of the coastal dunes later dammed the mouths of these drowned valleys diverting the drainage northwards and creating small back dune lakes in which predominantly organic sediments accumulated. A Preliminary study of one Gilligan Lake core suggests that the transition to a back dune lake may have been accompanied by a change in diatom assemblage from one in which eccentric monorapaphids and eunotoid species are prominent to an assemblage dominated by naviculoid forms.

Minimum surface ages are determined by a combination of cosmogenic radionuclide surface exposure ages, uranium-series and soil-development formation times. Bedrock incision rates of the Colorado River between approximately 500 ka and approximately 250ka, and approximately 250 ka to present are approximately 0.4 m/ka and approximately 0.7 m/ka, respectively. These rates are more than double the rates reported in the Grand Canyon, suggesting that the Colorado River above Lees Ferry is out of equilibrium with the lower section of the river. We also determine incision rates of two tributaries to the Colorado River. Oak Creek and Bridge Creek flow off Navajo Mountain into Glen Canyon from the southeast. Oak Creek and Bridge Creek both have incision rates of approximately 0.6 m/ka over the past approximately 100 ka at points about 9 km away from the main stem of the Colorado River.

The complex is constructed of granitic till from the late Pleistocene "Tioga" and "Tahoe" glacial advances. Cosmogenic nuclide surface exposure dates for these moraines are derived from cosmogenic nuclides that begin accumulating when the moraine crest boulders are exposed at the surface. In this study the cosmogenic nuclides are (super 26) Al and (super 10) Be. The concentrations of (super 26) Al and (super 10) Be increase over time at empirically derived production rates. Erosion of the moraine crest and exhumation of fresh unexposed or shielded boulders can cause the cosmogenic exposure age to be younger than the age of the moraine. To minimize the shielding effect caused by subsequent erosion of the moraine crest and exhumation of fresh (unexposed) boulders only the most prominent moraine crest boulders (2.3 to 4.0 m tall) were sampled. Chiseled flakes (2-5 cm thick) collected at the top of the boulders were processed and analyzed for (super 26) Al and (super 10) Be. The exposure ages were corrected for variations of the magnetic field intensity and pole position using the Stone, (2000) latitude and altitude correction factors and a sea level high latitude (super 10) Be production rate of 5.06. (super 26) Al ages were calculated using the Stone, (2000) latitude and altitude correction factors, assuming a (super 26) Al/ (super 10) Be production ratio of 6. The mean ( (super 26) Al and (super 10) Be) age for the "Tioga" moraine at Meeks Bay is 20.4 + or -0.7 ka yrs B.P.(n=4). The mean ( (super 26) Al and (super 10) Be) age for the "Tahoe" moraine at Meeks Bay is 62.0 + or -1.3 ka yrs B.P.(n=2). These cosmogenic exposure ages must strictly be considered minimum limiting ages that underestimate the true depositional age of the moraine. This underestimation of the moraine age is attributed to two processes: (1) erosion of the moraine and exhumation of shielded boulders, and (2) the unknown attenuation of the cosmic neutron flux caused by snow cover on boulders for as much as five to six months of the year. These processes could cause an underestimation of the apparent age.

A critical component of the program is to consider the major threats to groundwater resources that supply drinking water to Californians. Nitrate is the most pervasive and intractable contaminant in California groundwater and is the focus of special studies under the GAMA program. Two of the major potential sources of nitrate to groundwater are agricultural (synthetic fertilizers and animal waste as fertilizer or from confined animal operations), and near developed areas these sources may intermix with nitrate from septic tank leachate. Agricultural animal waste and septic leachate have associated organic carbon inputs, a necessary constituent for heterotrophic denitrification. Our research focuses on nitrate source attribution, on close examination of the parameters that govern denitrification, and on quantification of denitrification in the saturated zone. A multi-disciplinary approach employing N and O isotopes of nitrate, excess dissolved nitrogen, tritium-helium groundwater age dating, dissolved organics analysis, and advanced microbiological techniques allows identification of the dominant nitrate source and examination of its fate in groundwater, and provides a predictive capability for the probability that deep groundwater used for drinking water will become contaminated with nitrate. Examples from dairy sites where saturated zone denitrification has been quantified, and from groundwater basins affected by decades of irrigated agriculture using synthetic fertilizer, illustrate the power of this integrated analytical approach.

Energy released from these tests produced an estimated 7 X 105 kg of high-silica melt glass per kiloton of yield. For tests conducted below the water table, ground water re-infiltrates the test cavity at rates determined by the hydrologic properties of the surrounding geologic media. In low permeability environments, advective fluid transport of residual heat from the explosion is minimal, and elevated cavity temperatures can persist for decades after detonation. These conditions are conducive for accelerated water/glass reactions similar to hydrothermal and diagenetic alteration found in natural volcanic glasses. We recently examined samples of melt glass from the flooded cavity of a test conducted more than two decades ago. Groundwater temperatures at the time of sampling were approximately 75 degrees C. This study detected the zeolites clinoptilolite, erionite and/or mordenite formed on vesicle walls of melt glass that exhibited dissolution textures and discolored reaction rims. The dissolution textures are similar to those observed in partially perlitized obsidian, and the zeolites are similar to those observed on rhyolitic glass at nearby Yucca Mountain. Clay minerals (illite, smectite, and hectorite) were observed coating melt glass that exhibited no dissolution textures or reaction rims and are interpreted as coatings derived from drilling mud, although diagenetic formation of clay cannot be discounted. We conclude these zeolites formed from reactions with the melt glass at temperatures greater than 75 degrees C, and published thermodynamic data indicate the temperature of formation may have been as high as 125 degrees C.

In Antarctica, where glaciation by thin, cold ice protects underlying bedrock from erosion, concentrations of these nuclides provide million-year records of exposure and ice cover. Although we cannot recover the ages of specific glaciations, we can obtain (i) minimum limits on the total duration of past exposure and glaciation, and maximum limits on (ii) the relative proportion of time-exposed to time-covered by ice, and (iii) total exposure time during the last million years. Results from Marie Byrd Land show that: (i) Bedrock surfaces retain a memory of exposure and ice cover ranging from 0.4 Myr to more than 4 Myr. (ii) Mountain summits have the longest minimum cumulative exposure times, and record the greatest proportion of time exposed. (iii) Nonetheless, summits have spent a greater proportion of time ice-covered than exposed; maximum limits on exposure range from 1-4 Myr, in which the surfaces have been exposed for as little as 1% of the time. (v) These low-elevation surfaces cannot have been exposed for more than 90-2300 years if last exposed during marine isotope stage (MIS) 5e, or 170-3800 years if last exposed during MIS 11, believed to have been the warmest and most prolonged late Pleistocene interglacial.

The development of optically stimulated luminescence (OSL), cosmogenic radionuclide (CRN) surface exposure, and new technical advances in amino acid racemization (AAR) and U-series dating, however, now allows successions of sediments and landforms to be dated to define the timing and durations of various phases of development of a sedimentary record. Yet few studies provide intercomparisons between these techniques to test the validity and applicability of newly evolving methods, as well as established radiocarbon dating. To compare several dating techniques, we focused on a late Quaternary spit-beach complex in the Mojave Desert, CA where radiocarbon, OSL, CRN, AAR and U-series dating methods could be applied. Our results show that the spit-beach complex began to develop approximately 25 ka and has continued to evolve throughout the Holocene. TCN dates of approximately 25 ka, define the initial erosion of shoreline benches, while the radiocarbon dates of 15-9 ka, supported by AAR, for the spit show progressive lake level changes in Lake Mojave during the Lateglacial and early Holocene. In contrast, OSL dates suggest that the spit formed during the mid-late Holocene. High concentrations of detrital thorium within tuff inhibited the use of U-series dating at this site. This study illustrates that each of the geochronological methods contributes to an estimate of the timing and duration of a physical/geochemical event in the history of the spit-beach. Detailed studies at key sites, such as this, will help refine methods and will provide insights into new ways of utilizing numerical dating techniques to provide details on chemical and physical processes within arid and semi-arid environments.

Our work in the Pasco Basin, WA, combines cosmogenic burial dating ( (super 26) Al/ (super 10) Be) with magnetostratigraphy of sediments to establish more robust ages for these otherwise undatable deposits. Here we summarize data from two localities in the Pasco Basin, Cold Creek giant flood bar and Kiona Quarry. Both contain thick sections (30+ meters) of what are thought to be middle and early Pleistocene cataclysmic flood sediments and intercalated paleosols. Magnetostratigraphy from drill cores through the Cold Creek Bar (Pluhar et al., 2005 in press) suggests two reversed (or transitional) polarity zones separated by a normal zone. This had previously been interpreted as recording the Jaramillo normal subchron (0.99-1.07 Ma). However, eight preliminary cosmogenic burial ages on weak paleosols intercalated within Cold Creek bar suggest burial during the Brunhes normal chron (0-0.78 Ma). The burial dating therefore indicates that the polarity structure may record short-lived magnetic excursion(s) during the Brunhes. If true, this may permit more accurate geochronology of pre-LGM Missoula Flood sediments by correlation with excursions during the Brunhes. A surface exposure at Kiona Quarry, WA, also composed of cataclysmic flood sediments, yielded very different results. A pedogenically-altered gravel at this locality exhibits exponentially decreasing cosmogenic nuclide concentrations with depth, supporting its interpretation as a paleosol or paleosol remnant. Preliminary burial ages on this paleosol suggest burial during the early Pleistocene. This is consistent with the reversed polarity of the sediments directly beneath the paleosol, which indicates deposition prior to the Brunhes-Matuyama reversal at 0.78 Ma. These results emphasize that magnetostratigraphy is best combined with supplementary independent age indicators in order to determine uniquely the proper correlation with the magnetic polarity timescale. Furthermore, previous work that assigned ages based solely on paleomagnetic polarity should be reassessed in light of these new results.

Kongur in semi-arid region of northwestern Tibet from cosmogenic 10Be exposure dating AN - 51464412; 2007-034482 AB - The glaciation in Tibet and the Himalaya is essentially controlled by two major climatic systems; the mid-latitude westerlies and south Asian summer monsoon. To help resolve the relative importance of these climatic systems, we studied two massifs in northwestern Tibet, Mushtagata and Mt. Kongur, of which present day climates are influenced solely by the mid-latitude westerlies and is beyond the influence of the monsoon. Remote sensing, geomorphic mapping and cosmogenic Be-10 surface exposure dating of boulders on the moraines indicates that the glaciers of Mushatagata at 41-125ka, 17-71Ka, 17.8ka, 13.7ka, 10.5 ka, 8.2ka 6.5 ka, 4.5 ka, 1.8 ka and Little Ice Age. The temporal variations of glaciations of in this region are not in phase with other areas of the Tibetan Plateau that are dominantly affected by Indian Summer Monsoon, but are broadly synchronous with Northern Hemisphere. Interestingly, our data show that glaciations in the semi-arid northwestern Tibet since Last Glacial Maximum are likely linked to Northern Hemisphere cooling events (Rapid Climate Changes) by Mid-latitude Westerlies.

Although the potential benefits of longer chronologies are obvious, the greater uncertainties associated with older cosmogenic ages may be less readily apparent. We illustrate the challenges of developing and interpreting a long chronology using our data from the Peruvian Andes. We used the cosmogenic radionuclides (CRNs) (super 10) Be and (super 26) Al to date 140 boulders on moraines in valleys bordering the Junin Plain (11 degrees S 76 degrees W) in central Peru. Our chronology spans multiple glacial cycles and includes several zero-erosion exposure ages greater than 1 million years. The presence of surfaces with such old exposure ages indicates that long-term rates of boulder erosion are relatively low (on the order of 0.3-0.5 meters per million years). Interpreting the chronology of moraines for glaciations that predate the last glacial cycle is complicated by the need to consider loss of CRNs through boulder erosion, change in effective production rate through time due to surface uplift in this tectonically active region, introduction of younger surfaces through boulder exhumation resulting from moraine degradation, and inheritance of CRNs from previous exposure intervals. As an illustration, we recalculate exposure ages using our boulder erosion rates and published surface uplift rates, both of which increase the exposure ages. For example, a zero-erosion exposure age of 400,000 years increases by about 20% when boulder erosion and surface uplift are included in the calculations. Our results serve to emphasize both the challenges involved in interpreting old surface exposure ages and the rewards of having chronological data, even with uncertainties, when reconstructing the paleoclimate of a region.

HyMap hyperspectral imagery allowed us to map the distribution of hot spring and fumarolic minerals due to its high spatial and spectral resolution. Our mineral distribution maps of the Humboldt House area were validated in the field with a handheld spectrometer. The dominant N-NE trending linear distribution of hot spring and fumarolic minerals implies a structurally controlled deposition. Overlying all Lake Lahontan deposits, the hot spring outcrops are constrained to Holocene age and thus represent the most recent faulting expressions in the Rye Patch-Humboldt House geothermal district. In addition, using LiDAR data with 0.5m spot spacings and 15cm vertical resolution we documented deformation patterns in the Humboldt River Valley. The linkage of HyMap-generated mineral maps with LiDAR-generated digital elevation models allows for accurate mapping of fault scarps, hot spring mounds, dune sands, and fluvial deposits. Hyperspectral and LiDAR remote sensing methods together provide an outstanding set of tools for geothermal resource exploration, fault mapping, and geomorphic characterization.

At a contaminated groundwater site near Fairbanks, Alaska, isotopic analysis of benzene and toluene and measurement of benzylsuccinate and methylbenzylsuccinates was carried out to assess in situ biodegradation. The combined use of both techniques was particularly valuable in this subarctic environment where biodegradation rates can be slow and demonstrating biodegradation can be difficult using other methods. delta (super 13) C and delta (super 2) H analysis of benzene suggested that biodegradation of this contaminant was unlikely at this site. In contrast, an isotopic enrichment in delta (super 13) C of 2ppm and enrichment in delta (super 2) H of 70ppom in toluene occurred, suggesting in situ toluene biodegradation. Xylene and toluene biodegradation was also supported by the presence of 17-50 mu g/L of methylbenzylsuccinate and 10-49 mu g/L of benzylsuccinate. A comparison of isotopic and benzylsuccinate analysis for demonstrating anaerobic toluene biodegradation at this site is useful. Toluene biodegradation was indicated by the presence of benzylsuccinate in the three wells with the highest concentrations of toluene. Benzylsuccinate concentrations are typically much lower than that of toluene in groundwater. As such, in the wells with lower concentrations of toluene, benyzylsuccinate concentrations were below detection limits. In contrast, isotopic analysis works best for samples in which a large fraction of the toluene has been degraded, since significant isotopic fractionation is often not resolvable until a large extent of biodegradation occurs. Hence, in the higher concentration wells, delta (super 13) C and delta (super 2) H values for toluene agreed within error and provided no evidence of biodegradation. In contrast, in samples with lower toluene concentrations, while benzylsuccinate was below detection limits, isotopic enrichment in (super 13) C and (super 2) H of toluene provided evidence of biodegradation. Analysis of metabolites may therefore provide the earliest evidence of biodegradation, while stable carbon and hydrogen isotopes may continue to provide support for biodegradation in less contaminated wells where metabolites may be below detection limits.

As a result, a radiologic source term consisting of tritium, fission products, activation products and actinides remains underground following the nuclear test. The U.S. Department of Energy is tasked with investigating the distribution and /or potential migration of the radionuclides in groundwater at the NTS. An accurate assessment of risk for human health down-gradient from the testing centers requires understanding of how the radionuclides migrate. Our lack of knowledge regarding the extent to which colloids facilitate transport of low-solubility radionuclides, such as plutonium (Pu), currently limits our efforts to develop reliable transport models. Two sets of experiments were carried out to understand better the mechanisms controlling colloid-facilitated transport of Pu in fractured rock. The first set of experiments was conducted using rhyolitic tuff and the second using carbonate fractured rock. One set of fractures were injected with a radionuclide cocktail of dissolved species, and the second injected with pseudocolloids consisting of Pu(IV) sorbed to either zeolite or clay. Tritium and Re (analog to Tc) tracers were also added to a NTS-type synthetic groundwater (4.5mM NaHCO3-). The cocktail was injected into a smooth fracture surfaces and the effluent analyzed. Efforts to characterize the fractured surface to investigate the location of the sorbed Pu by autoradiography and secondary ion mass spectrometry will be presented. In the rhyolitic tuff, less than 5% of the dissolved Pu was eluted through the column. In contrast, approximately 30% of the Pu sorbed onto the zeolite colloids was eluted through the tuff. Pu was transported more effectively through the carbonate cores than the tuff. In both cases, Pu appears to be mineralogically controlled within the cores. This work was performed under the auspices of the U.S. Department of Energy by University of California, Lawrence Livermore National Laboratory under Contract W-7405-Eng-48.

A complete physical picture that explains widely observed variations in dissolution behavior is lacking, and some data show apparent serious inconsistencies that cannot be explained by the largely empirical kinetic "laws." Here, we show that mineral dissolution can, in fact, be understood through the same mechanistic theory of nucleation developed for mineral growth. In principle, this theory should describe dissolution but has never been tested. By generalizing nucleation rate equations to include dissolution, we arrive at a model that predicts how quartz dissolution processes change with undersaturation from step retreat, to defect-driven and homogeneous etch pit formation. This finding reveals that the "salt effect," recognized almost 100 years ago, arises from a crossover in dominant nucleation mechanism to greatly increase step density. The theory also explains the dissolution kinetics of major weathering aluminosilicates, kaolinite and K-feldspar. In doing so, it provides a sensible origin of discrepancies reported for the dependence of kaolinite dissolution and growth rates on saturation state by invoking a temperature-activated transition in the nucleation process. Although dissolution by nucleation processes was previously unknown for oxides or silicates, our mechanism-based findings are consistent with recent observations of dissolution (i.e., demineralization) in biological minerals. Nucleation theory may be the missing link to unifying mineral growth and dissolution into a mechanistic and quantitative framework across the continuum of driving force.

Towards the end of the last glacial period, as global sea level rose, the Caribbean Sea flooded the valley, producing a seaway in which fringing reefs developed ( approximately 9-5 ka). For 3,500 years of that time, extensive ( approximately 11m in height), monospecific reefs of Acropora cervicornis accumulated. By 5 ka, serpulid worms had replaced Acropora cervicornis as the dominant reef species. Because the cervicornis outcrop in the Enriquillo Valley is so well exposed, collection of samples at high resolution (2 cm intervals) is possible. X-Ray diffraction analyses have shown that 68 of 122 samples from the outcrop are pure aragonite, with the lower part of the outcrop more poorly preserved. (super 234) U/ (super 230) Th dating indicates that Acropora cervicornis flourished from approximately 9.45 to approximately 6.06 ka. The 9.45 ka date, however, may not suggest a seawater environment. Based upon these dates, Acropora cervicornis accumulated twice as rapidly from 9.45 to 8.66 ka as it did during later periods. (super 14) C dates are also being determined for 50 samples at 20 cm intervals throughout the outcrop. The first ten of these conventional radiocarbon dates (8.72 to 7.96 ka) demonstrate that Acropora cervicornis accumulated consistently in correct stratigraphic sequence with few interruptions. The only evidence of mixing may suggest that a large storm event occurred approximately 8.40 ka. The stable isotope values of Acropora cervicornis samples from this outcrop reveal significant environmental changes during reef formation. Data show that mean delta (super 18) O decreased from -0.9 to -2.2ppm, while mean delta (super 13) C increased from -4.5 to -1.4ppm from approximately 9.45 to approximately 6.06 ka. These data suggest a decrease in salinity of the Lago Enriquillo embayment due to an increase in precipitation associated with the thermal maximum at 6 ka. High resolution stable isotope data may also reveal changes in seasonality throughout the Holocene.

Analyses complementing DeCyder are suggested by incorporating recent advances from the microarray data analysis literature. A case study on the effect of smallpox vaccination is used to compare the results obtained from DeCyder with the results obtained by applying moderated t-tests adjusted for multiple comparisons to DeCyder output data that was additionally normalized. RESULTS: Application of the more stringent statistical tests applied to the normalized 2D DIGE data decreased the number of potentially differentially expressed proteins from the number obtained from DeCyder and increased the confidence in detecting differential expression in human clinical studies.

These types of records have recently been constructed using coralline sponges. Because they are found in a greater range of depths, coralline sponges have the potential to fill in gaps in our understanding of subsurface oceanographic variability. Using coralline sponges together with surface corals, we can obtain a threedimensional (3D) picture of oceanographic/climate variability. However, coralline sponges have one disadvantage compared to hermatypic reef building coral proxies in that most do not have annual density bands and need to be radiometrically dated for age determination. We have measured radiocarbon in 1 mm increments from Astrosclera willeyana sponges collected off the Central and Northern Great Barrier Reef (GBR) and from Truk in the Caroline Islands and compared these radiocarbon profiles to independently dated coral radiocarbon records to examine growth rate variability. Growth rates of the GBR sponges averaged 1.2 plus or minus 0.3 and 1.0 plus or minus 0.3 mm y super(-1) at north and central sites respectively, but the growth rate can vary by a factor of two over the life span of the sponge. The growth rate of the Truk sponge averaged 1.2 plus or minus 0.1 mm y super(-1). These growth rates are faster than those measured for other Astrosclera willeyana sponges (0.2-0.7 mm y super(-1)) (Moore et al. 2000; Worheide 1998).

We investigated the cytogenetic adaptive response of human lymphoblastoid cell lines exposed to 5 cGy (priming dose) followed by 2 Gy (challenge dose) compared to cells that received a single 2-Gy dose to (a) determine how the priming dose influences subsequent gene transcript expression in reproducibly adapting and non-adapting cell lines, and (b) identify gene transcripts that are associated with reductions in the magnitude of chromosomal damage after the challenge dose. The transcript profiles were evaluated using oligonucleotide arrays and RNA obtained 4 h after the challenge dose. A set of 145 genes (false discovery rate = 5%) with transcripts that were affected by the 5-cGy priming dose fell into two categories: (a) a set of common genes that were similarly modulated by the 5-cGy priming dose irrespective of whether the cells subsequently adapted or not and (b) genes with differential transcription in accordance with the cell lines that showed either adaptive or non-adaptive outcomes. The common priming-dose response genes showed up-regulation for protein synthesis genes and down-regulation of metabolic and signal transduction genes (>10-fold differences). The genes associated with subsequent adaptive and non-adaptive outcomes involved DNA repair, stress response, cell cycle control and apoptosis. Our findings support the importance of TP53-related functions in the control of the low-dose cytogenetic radioadaptive response and suggest that certain low-dose-induced alterations in cellular functions are predictive for the risk of subsequent genomic damage.

Downcore profiles of delta (super 18) O of N. pachyderma (s.) and U. auberiana, carbonate and organic carbon contents, species changes in the planktonic foraminifera assemblages and some diatom species show orbital (MIS 1, 2 and 3) and millennium scale variability influenced by the Alaska Current flowing into the studied region. Three warmer episodes in the southern Bering Sea environment were assumed to be synchronous with DO interstadials 8, 12 and 14 (in GISP-2 chronology) during MIS 3. More severe climate and environmental conditions in the southern Bering Sea during MIS 2 occurred synchronously with the LGM within a 17-19 ka time span. Two well pronounced environmental warming events, productivity spikes and changes in the pore water geochemistry, separated by Younger Dryas cooling, were observed at the base of MIS 1 coeval with MWP 1A and 1B. Regional glacial primary productivity based on the calculation of the organic carbon MAR, similar to that found in the far northwestern Pacific, exceeded the Late Holocene values under conditions close to the present day.

To explore the rates of C cycling in temperate forest soils, we took advantage of a unique opportunity in the form of an inadvertent stand-level (super 14) C-labeling originating from a local industrial release. A simple density fractionation scheme separated SOM into inter-aggregate particulate organic matter (free light fraction, free LF), particulate organic matter occluded within aggregates (occluded LF), and organic matter that is complexed with minerals to form a dense fraction (dense fraction, DF). Minimal agitation and density separation was used to isolate the free LF. The remaining dense sediment was subjected to physical disruption and sonication followed by density separation to separate it into occluded LF and DF. The occluded LF had higher C concentrations and C:N ratios than the free LF, and the C concentration in both light fractions was ten times that of the DF. As a result, the light fractions together accounted for less than 4% of the soil by weight, but contained 40% of the soil C in the 0-15 cm soil increment. Likewise, the light fractions were less than 1% weight of the 15-30 cm increment, but contained more than 35% of the soil C. The degree of SOM protection in the fractions, as indicated by Delta (super 14) C, was different. In all cases the free LF had the shortest mean residence times. A significant depth by fraction interaction for (super 14) C indicates that the relative importance of aggregation versus organo-mineral interactions for overall C stabilization changes with depth. The rapid incorporation of (super 14) C label into the otherwise depleted DF shows that this organo-mineral fraction comprises highly stable material as well as more recent inputs.

In a single run, this reliable, sensitive, and robust method can simultaneously separate and quantify halides (fluoride, chloride, bromide, and iodide) and up to seven FBAs from other common groundwater constituents (e.g. nitrate and sulphate). The usefulness of this analytical method is demonstrated in both field and laboratory tracer experiments. The field study examines the hydrologic response of fractures and the matrix to different flow rates and the contribution of matrix diffusion in chemical transport. Laboratory tracer experiments with eight geologic media from across the USA--mostly from Department of Energy facilities where groundwater contamination is prevalent and where subsurface characterization employing tracers has been ongoing or is in need--reveal several insights about tracer transport behaviour: (1) bromide and FBAs are not always transported conservatively; (2) the delayed transport of these anionic tracers is likely related to geologic media characteristics, such as organic matter, pH, iron oxide content, and clay mineralogy; (3) use of iodine as a hydrologic tracer should take into account the different sorption behaviours of iodide and iodate and the possible conversion of iodine's initial chemical form; (4) the transport behaviour of potential FBA and halide tracers under relevant geochemical conditions should be evaluated before beginning ambitious, large-scale field tracer experiments.

In smaller and intermittent streams, a large storm may transport a majority of the annual sediment budget. Therefore, monitoring techniques that can measure high suspended sediment concentrations at semi-continuous time intervals are needed. A fiber optic in-stream transmissometer (FIT) is presented and laboratory tested for continuous measurement of high concentration suspended sediment in flowing water. FIT performance and precision were demonstrated to be reasonably good for suspended sediment concentrations up to 10 g/L. The FIT was compared in laboratory tests to two commercially available turbidity devices and provided better precision and accuracy at both high and low concentrations. Both turbidity devices were unable to collect measurements at concentrations greater than 4 g/L. The FIT and turbidity measurements were sensitive to sediment particle size. Particle size dependence of transmittance and turbidity measurement poses the greatest problem for calibration to suspended sediment concentration. While the FIT was demonstrated to provide acceptable measurements of high suspended sediment concentrations in these studies, approaches to real-time suspended sediment detection need to address the particle size dependence in concentration measurements.

In contrast to previous experiments on Mg partitioning into calcite, here the layer-growth mechanism was observed in situ and step speeds precisely measured with fluid cell atomic force microscopy over a range of temperatures, degrees of supersaturation, and solution Mg concentrations. Data collected from 15 degrees to 30 degrees C yield an activation energy for calcite precipitation of 33 kJ/mol for solutions with [Mg] = 5X10 (super -5) molal. Electron microprobe analyses of large hillocks grown at corresponding conditions demonstrate that Mg has a strong preference for incorporation at negative (acute) step edges, rather than at positive (obtuse) edges when growth rate is limited by surface reactions. This preference is reversed when growth is instead limited by diffusion of reactants through a boundary layer at the mineral-solution interface. These findings show that temperature is not the only strong control on the extent of Mg incorporation and distribution in calcite; transport conditions during mineral growth may also be a first-order factor governing the compositions of natural calcite samples.

Our goal is to provide first-order results from various CO (sub 2) pathways, allowing correspondence with studies of marine biological effects of added CO (sub 2) . Parts of the Southern Ocean become undersaturated with respect to aragonite under the Intergovernmental Panel on Climate Change Special Report on Emissions Scenarios (SRES) A1, A2, B1, and B2 emission pathways and the WRE pathways that stabilize CO (sub 2) at 650 ppm or above. Cumulative atmospheric emission of 5000 Pg C produces aragonite undersaturation in most of the surface ocean; 10,000 Pg C also produces calcite undersaturation in most of the surface ocean. Stabilization of atmospheric CO (sub 2) at 450 ppm produces both calcite and aragonite undersaturation in most of the deep ocean. (mod. journ. abst.)

The oldest landforms we studied are extensive alluvial fans referred to as "Atacama gravels". With the exception of samples collected in Antarctica, the cobbles collected on these alluvial surfaces have the lowest erosion rates of any samples, as determined by cosmogenic nuclides, analyzed to date. The oldest cobble has a model surface exposure age of 9 Myr, based on combined measurements of cosmogenic (super 10) Be, (super 26) Al, and (super 21) Ne concentrations. Cobbles from the alluvial fans are eroding slower than the surrounding steep mountainous bedrock surfaces. Maximum erosion rates for cobbles on alluvial surfaces are uniformly <0.1 m/Myr. The survival of these gravels, specifically, and more generally, the stability of landform features in this geographic area is made possible by the attainment of hyperarid conditions in the Atacama Desert resulting from global climatic cooling about 15 Myr ago combined with the rain shadow effect caused by uplift of the Central Andes. The landform features observed presently in the Atacama Desert are remarkably stable and, despite the inevitable erosion that is detectable using cosmogenic nuclides, undoubtedly bear considerable resemblance to conditions as they existed in the Miocene. Over geologic time, the Atacama landscape is evolving in such a manner as to erode the higher bedrock ridges relative to the more stable, but stratigraphically lower depositional surfaces through which clastic detritus now travels occasionally along the floors of incised drainage systems leaving the older permeable alluvial fan surfaces largely intact as widespread remnants of a Miocene fossil landscape.

Recent advances in Accelerator Mass Spectrometry (AMS) and sample preparation techniques have reduced the sample-size requirements by a factor of 1000 and decreased the measurement time from weeks to minutes. Today, it is estimated that more than 90 percent of all measurements made on accelerator mass spectrometers are for radiocarbon age dates. The production of (super 14) C in the atmosphere varies through time due to changes in the Earth's geomagnetic field intensity and in its concentration, which is regulated by the carbon cycle. As a result of these two variables, a radiocarbon age is not equivalent to a calendar age. Four decades of joint research by the dendrochronology and radiocarbon communities have produced a radiocarbon calibration data set of remarkable precision and accuracy extending from the present to approximately 12,000 calendar years before present. This paper presents high precision paired (super 230) Th/ (super 234) U/ (super 238) U and (super 14) C age determinations on pristine coral samples that enable us to extend the radiocarbon calibration curve from 12,000 to 50,000 years before present. We developed a statistical model to properly estimate sample age conversion from radiocarbon years to calendar years, taking full account of combined errors in input ages and calibration uncertainties. Our radiocarbon calibration program is publicly accessible at: http://www.radiocarbon.LDEO.columbia.edu/ along with full documentation of the samples, data, and our statistical calibration model.

The surrogate biological warfare agent used in experiments was the spore-forming bacterium Bacillus atrophaeus. Viable-spore-counting methods were used in the study because they provide the most important number for estimating human health effects. Three common ventilation duct materials were evaluated: flexible plastic, galvanized steel, and internally insulated fiberglass. Transport efficiency ranged from 9 to 13% in steel and fiberglass ducts; transport efficiency was far less (0.1-4%) in plastic duct. Results showed that the deposition of surrogate biological warfare agent was significantly different in the three duct materials evaluated. All experimentally determined, dimensionless deposition velocities were in the range of theoretical predictions for dimensionless roughness, k super(+)=10. All were 10-100 times greater than the velocities predicted for ducts with smoother surfaces, k super(+)=0.1. For plastic duct, greater dimensionless deposition velocities were likely the result of charge forces between spores and surface. However, for the steel duct, a relatively large dimensionless deposition velocity was unexpected. These findings imply that building contamination will likely vary, depending on the specific type of duct material used throughout an affected area. Results of this study may aid in refining existing particle-transport models and remediation activities.

This approach is used to design a material that is effective at reducing the dissolved organic components of produced water. This study reports the initial results of removing dissolved hydrophobic organics using a hydrophobic (CH sub(2)CH sub(2)CF sub(3)) surface group on the silica aerogel. The 30% by weight formulation CF sub(3)-aerogel was able to adsorb dissolved organic species with log K sub(ow)?>?2.0, with adsorption affinity increasing with increasing log K sub(ow). Seawater salinities did not have a large effect on the adsorption of aromatic compounds. Most dissolved aromatics and organic acids with the same log K sub(ow) that were tested had differing affinities for the CF sub(3)-aerogel, with the aromatics affinity being greater. These results show the utility of modifying the aerogel surface hydrophobicity for absorbing hydrophobic dissolved organic compounds.

We performed step-wise hydrostatic pressurization tests on 5 samples to maximum pressures P of 150 MPa, using relatively tight (0.18-0.25 mm) and broad (0.25-2.0 mm) starting grain-size distributions. Compaction change of volume is highly nonlinear in P, typical for brittle, granular materials. No time-dependent creep occurred on the lab time scale. Significant residual porosity (0.10) remains even at highest P. Examination by scanning electron microscopy (SEM) reveals a random configuration of fractures and broad distribution of grain sizes, again consistent with brittle behavior. Residual porosity appears as smaller, well-supported micropores between ice fragments. Over the interior pressures found in smaller midsize icy satellites and Kuiper Belt objects (KBOs), substantial porosity can be sustained over solar system history in the absence of significant heating and resultant sintering.

AN - 68011085; 15982874 AB - One-electron oxidation of 7,8-dihydro-8-oxo-2'-deoxyguanosine (8-oxodG) yielded a guanidinohydantoin derivative (dGh) and a spiroiminodihydantoin derivative (dSp), both putatively mutagenic products that may be formed in vivo. The nucleoside dGh was the major product at room temperature, regardless of pH. The results are contrary to previously published model studies using 2',3',5'-triacetoxy-8-oxo-7,8-dihydroguanosine (Luo, W.; Miller, J. G.; Rachlin, E. M.; Burrows, C. J. Org. Lett. 2000, 2, 613; Luo, W.; Miller, J.G.; Rachlin, E.M.; Burrows, C.J. Chem. Res. Toxicol. 2001, 14, 927), who observed a spiroiminodihydantoin derivative as the major product at neutral pH. Clearly, the functional groups attached to the ribose moiety of 8-oxodG influence the oxidation chemistry of the nucleobase derivative. To explore this chemistry in vivo, (14)C-labeled 8-oxodG was synthesized and incubated with growing MCF-7 human breast cancer cells, resulting in the incorporation of the compound into cellular DNA as measured by a novel accelerator mass spectrometry assay.

Caves dated by (super 26) Al/ (super 10) Be in buried sediments reveal that river incision rates were moderate to slow between c. 5 and 3 Ma (< or =0.07 mm a (super -1) ), accelerated between 3 and 1.5 Ma (c. 0.3 mm a (super -1) ), and then have subsequently become much slower (c. 0.02 mm a (super -1) ). Although the onset of accelerated incision coincides in time with both postulated Pliocene tectonism and pronounced global climate change, we argue that it primarily represents the response to a discrete tectonic event between 3 and 5 Ma. Dated cave positions reveal that, prior to 3 Ma, river canyons displayed up to 1.6 km of local relief, suggesting that Pliocene rock uplift elevated pre-existing topography. Renewed incision beginning c. 3 Ma deepened canyons by up to 400 m, creating narrow inner gorges. Tributary streams exhibit strong convexities, indicating that the transient erosional response to Pliocene uplift has not yet propagated into upland surfaces. Concentrations of (super 26) Al and (super 10) Be in bare bedrock show that upland surfaces are eroding at slow rates of c. 0.01 mm a (super -1) . Over the past c. 3 Ma, upland surfaces eroded slowly while adjacent rivers incised rapidly, increasing local relief. Although relief production probably drove at least modest crestal uplift, considerable pre-Pliocene relief and low spatially averaged erosion rates suggest that climatically driven rock uplift is not sufficient to explain all uplift implied by tilted markers at the western edge of the range. Despite the recent pulse of erosion, spatially averaged erosion rates are low, and have probably acted to preserve the broad topographic form of the Sierra Nevada throughout much of the late Cenozoic.

Millennial-scale erosion rates and dominant controls on erosion patterns in this range are poorly known. To define these patterns, we present 48 erosion rate estimates, derived from analysis of in situ (super 10) Be in quartz-bearing alluvium collected from the Upper Beni River basin. Erosion rates, corrected for the non-uniform distribution of quartz in the sample basins, range from 0.04 mm a (super -1) to 1.35 mm a (super -1) and thus integrate over 10 (super 2) -10 (super 4) years. Mean and modal values are 0.42 (standard deviation: 0.29) and 0.2-0.4 mm a (super -1) respectively, within the range of long-term average erosion rates in this area derived from apatite fission track thermochronology (0.1-0.6 mm a (super -1) ). Hence, our data do not record any significant variation in erosion rate over the last several million years. Mean and modal short-term erosion rates for the Andes are an order of magnitude lower than rates in the Ganges River headwaters in the High Himalaya and an order of magnitude greater than rates typical of the European Alps. In the Upper Beni River region of the Bolivian Andes, short-term, basin-averaged erosion rates correlate with normalized channel steepness index, a metric of relative channel gradient corrected for drainage area. Neither normalized channel steepness index nor basin-averaged erosion rate shows strong correlation with mean basin hillslope gradient or mean basin local relief because many hillslopes in the Upper Beni River region are at threshold values of slope and local relief. Patterns of normalized channel steepness index appear primarily to reflect tectonic patterns and transient adjustment to those patterns by channel networks. Climate and lithology do not appear to exert first-order controls on patterns of basin-averaged erosion rates in the Bolivian Andes. Abstract Copyright (2005), Wiley Periodicals, Inc.

Here we calculate episodic incision rates of the Colorado River based on absolute ages of two levels of Quaternary deposits adjacent to Glen Canyon, Utah, along the north flank of Navajo Mountain. Minimum surface ages are determined by a combination of cosmogenic radionuclide surface exposure ages, uranium series and soil-development formation times. Bedrock incision rates of the Colorado River between c. 500 ka and c. 250 ka, and c. 250 ka to present are c. 0.4 m ka (super -1) and c. 0.7 m ka (super -1) , respectively. These rates are more than double the rates reported in the Grand Canyon, suggesting that the Colorado River above Lees Ferry is out of equilibrium with the lower section of the river. We also determine incision rates of two tributaries to the Colorado River. Oak Creek and Bridge Creek flow off Navajo Mountain into Glen Canyon from the southeast. Oak Creek and Bridge Creek both have incision rates of c. 0.6 m ka (super -1) over the past c. 100 ka at points about 9 km away from the main stem of the Colorado River.

Detailed measurements of sediment fluxes in the Northern California Coast Ranges at Caspar Creek and Redwood Creek have provided estimates of physical erosion rates since 1963 and 1971, respectively. We used cosmogenic (super 10) Be to measure millennial-scale denudation rates averaged over 1400-8700 years at six catchments in Caspar Creek and four catchments in Redwood Creek. Our (super 10) Be measurements at Caspar Creek imply denudation rates that are nearly spatially uniform across the entire catchment and average 0.09+ or -0.02 mm a (super -1) . These millennial-scale rates implied by cosmogenic (super 10) Be are faster than physical erosion rates of 0.005+ or -0.001 mm a (super -1) to 0.046+ or -0.007 mm a (super -1) inferred from sediment flux measurements over the past few decades in the same catchments. At Redwood Creek, our cosmogenic (super 10) Be measurements imply millennial-scale denudation rates that vary across the catchment from 0.14+ or -0.03 mm a (super -1) to 0.44+ or -0.09 mm a (super -1) , in contrast to physical erosion rates ranging from 0.038+ or -0.011 mm a (super -1) to 0.48+ or -0.09 mm a (super -1) derived from sediment flux measurements made over the past few decades at the same catchments. The decadal-scale and millennial-scale measurements tend to differ most at the smallest tributaries, but differ by less than a factor of three for the Caspar Creek and Redwood Creek catchments as a whole. These measurements suggest that denudation rates at Caspar Creek are slower than rock uplift rates of 0.3-0.4 mm a (super -1) , implying that Caspar Creek is not in topographic steady state.

Using isotopic analysis of both headwater and downstream samples, we determined that the semi-arid, Rio Puerco Basin is eroding, on average, about 100 m Ma (super -1) . This rapid rate of erosion is consistent with estimates made using other techniques and is likely to result from a combination of easily eroded lithologies, sparse vegetation, and monsoon-dominated rainfall. Data from 331 stream water samples collected by the US Geological Survey between 1960 and 1995 are consistent with basin-wide, average chemical denudation rates of only about 1.4 m Ma (super -1) ; thus, the erosion rates we calculate may be considered rates of sediment generation because physical weathering accounts for almost 99 per cent of mass loss. The isotopic data reveal that sediment is generally well mixed downstream with the area-weighted average sediment generation rate for 16 headwater samples (234 ton km (super -2) a (super -1) for basin area 170 to 1169 km (super 2) ) matching well that estimated from a single sample collected far downstream (238 ton km (super -2) a (super -1) , basin area = 14 225 km (super 2) ). A series of 15 samples, collected from an arroyo wall and representing deposition through the late Holocene, indicates that (super 10) Be concentration in sediment delivered by the fluvial system has not changed appreciably over the last 1200 years despite at least two cycles of arroyo cutting and filling. Other samples (n = 21) were collected along the drainage network. Rio Puerco erosion rates scale directly with a variety of metrics describing vegetation, precipitation, and rock erodibility. Using the headwater basins for calibration, the erosion rates for both the downstream samples and also the data set as a whole, are best modelled by considering a combination of relief and vegetation metrics, both of which co-vary with precipitation and erodibility as inferred from lithology. On average, contemporary sediment yields, determined by monitoring suspended-sediment discharge, exceed cosmogenically determined millennial-scale erosion rates by nearly a factor of two. This discrepancy, between short-term rates of sediment yield and long-term rates of erosion, suggests that more sediment is currently being exported from the basin than is being produced. Because the failure of incised channel walls and the head cutting of arroyo complexes appear to be the main sources of channel sediment today, this incongruence between rates of sediment supply and sediment yield is likely to be transitory, reflecting the current status of the arroyo cycle and perhaps the influence of current or past land-use patterns.

Measurements of in situ terrestrial cosmogenic nuclide (TCN) concentrations from 31 bedrock sites, coupled with soils and geomorphology, indicate that erosion of the valleys has been >2 m during a single glacial-interglacial cycle. However, on summit plateaus the long-term (over several glacial-interglacial cycles) erosion rate is <1.4 m Ma (super -1) . TCN ratios reveal that the exposure plus ice-cover history retained on some summit surfaces probably spans more than 800 ka despite complete ice cover as recently as 11 ka. A thermodynamic ice sheet model with a basal water calculation is used to calculate the sliding distance normalized by the duration of ice cover for the region. We formulate a general glacial erosion rule for the Torngat Mountains, which correlates TCN-derived erosion rates for terrain once partially covered by cold-based ice with modelled average ice basal sliding velocities. Erosion rates vary linearly with average sliding velocity by a glacial erosion coefficient of 5X10 (super -7) . Due to the significant distribution of cold-based ice cover in this high latitude region, our estimates of net regional glacial erosion and glacial erosion coefficient are orders of magnitude lower than a previously published value.

Boulder exhumation during moraine degradation likely gives rise to the largest uncertainty in constraining the timing of initial moraine stabilization following ice retreat. Isotopic inheritance appears to be most important for moraines deposited close to their cirque headwalls. Boulder-surface (bedrock) erosion rate can be roughly constrained and leads to a range in moraine stabilization ages. Snow-cover history is difficult to constrain, but its effect is thought to be minor for the tall boulders sampled.Despite these complications, the CE ages provide important new information regarding the timing of the last and penultimate glaciations in Alaska. Three penultimate moraines yielded CE ages that overlap with marine isotope stage (MIS) 4/early MIS 3 (45-65 ka) rather than MIS 6 (ca. 140 ka). Based on a combination of our new CE chronologies and existing (super 14) C ages from six study areas, glaciers retreated from their local late Wisconsin maxima: ca. 24-27 ka, Kokrines Hills (west-interior Alaska); ca. 24-26 ka, northeastern Brooks Range (NE Alaska); ca. 21-23 ka, Yukon Tanana Upland (east-interior Alaska); ca. 22 ka, Ahklun Mountains (SW Alaska); ca. 20 ka, western Alaska Range (central Alaska); ca. 16-18 ka, Chuilnuk Mountains (SW Alaska). Overall, glacier retreat was concurrent with the peak of the last global glacial maximum, probably in response to limited moisture availability.

Radioiodine originates in the surface environment almost entirely from anthropogenic activities such as nuclear fuel reprocessing in Europe and thus provides a unique point source tracer. Very few studies have evaluated the geochemical behavior of I isotopes in the subsurface. In this study, the concentrations of (super 129) I and (super 127) I were measured in wells fed by a series of artificial recharge ponds in the Forebay Area of the Orange County ground water basin (California, USA) to evaluate their potential use as hydrological tracers. To substantiate interpretation of (super 129) I and (super 127) I concentration data, the aquifer system was evaluated using the literature values of aquifer water mass age based on (super 3) H/ (super 3) He, Xe and delta (super 18) O tracer data. The aquifer data demonstrate the nearly conservative behavior of (super 129) I with (super 129) I/ (super 127) I ratios likely reflecting variations in source functions as well as climatic conditions, and with inferred particle-water partition coefficients (K (sub d) ) of 0.1 cm (super 3) g (super -1) or less.

During the boreal winter/spring, it is manifested as an eastward propagating disturbance, with a strong convective signature over the eastern hemisphere. The space-time structure of the MJO is analyzed using simulations with the ECHAM4 atmospheric general circulation model run with observed monthly mean sea-surface temperatures (SSTs), and coupled to three different ocean models. The coherence of the eastward propagation of MJO convection is sensitive to the ocean model to which ECHAM4 is coupled. For ECHAM4/OPYC and ECHO-G, models for which ~100 years of daily data is available, Monte Carlo sampling indicates that their metrics of eastward propagation are different at the 1% significance level. The flux-adjusted coupled simulations, ECHAM4/OPYC and ECHO-G, maintain a more realistic mean-state, and have a more realistic MJO simulation than the nonadjusted scale interaction experiment (SINTEX) coupled runs. The SINTEX model exhibits a cold bias in Indian Ocean and tropical West Pacific Ocean sea-surface temperature of ~0.5 degree C. This cold bias affects the distribution of time-mean convection over the tropical eastern hemisphere. Furthermore, the eastward propagation of MJO convection in this model is not as coherent as in the two models that used flux adjustment or when compared to an integration of ECHAM4 with prescribed observed SST. This result suggests that simulating a realistic basic state is at least as important as air-sea interaction for organizing the MJO. While all of the coupled models simulate the warm (cold) SST anomalies that precede (succeed) the MJO convection, the interaction of the components of the net surface heat flux that lead to these anomalies are different over the Indian Ocean. The ECHAM4/OPYC model in which the atmospheric model is run at a horizontal resolution of T42, has eastward propagating zonal wind anomalies and latent heat flux anomalies. However, the integrations with ECHO-G and SINTEX, which used T30 atmospheres, produce westward propagation of the latent heat flux anomalies, contrary to reanalysis. It is suggested that the differing ability of the models to represent the near-surface westerlies over the Indian Ocean is related to the different horizontal resolutions of the atmospheric model employed.

Rank correlation analyses were used to examine the relationship between pond surface area and species richness of all species collectively and of autogenic species and allogenic species separately. A positive relationship was found for allogenic species, whereas there was no association for all species, nor was there an association when the study was restricted to autogenic species. Mantel tests were used to determine the relationship between geographic distance and community dissimilarity for all species and for autogenic and allogenic species independently. Total community dissimilarity and allogenic dissimilarity were found to be influenced by geographic distance, whereas autogenic dissimilarity was random with regard to interpond distances. These findings serve to illustrate the importance of the autogenic-allogenic dichotomy and demonstrate that dispersal ability can influence commonly observed ecological patterns.

A well known problem is that the sub-tropical Southern Hemisphere T sub(O) implied by many models is equatorward, contrary to most observationally-based estimates. By correcting the T sub(O) of a diversity of models with satellite-derived observations, an earlier study demonstrated that the dominant T sub(O) problems could be explained by model errors in cloud radiative effects. Such errors were argued to be primarily responsible for the erroneous Southern Hemisphere T sub(O). However, systematic evaluation of one model in a later study suggested that the equatorward Southern Hemisphere T sub(O) might also be attributable to biases in the ocean surface latent heat flux. In this study we revisit the problem with a more recent suite of simulations, and demonstrate that collectively models have improved, but only slightly. We then use ocean surface fluxes estimates to examine the problem from a surface point of view. Our results clarify that common model errors in the surface latent heat flux can afflict T sub(O) as dramatically as errors in cloud radiative effects. To illustrate the relative importance of the two errors, diagnostic tests are introduced that should become increasingly useful as estimates of ocean surface fluxes are improved.

AN - 67981457; 15905278 AB - MOTIVATIONSpecific and sensitive ligand-based protein detection assays that employ antibodies or small molecules such as peptides, aptamers or other small molecules require that the corresponding surface region of the protein be accessible and that there be minimal cross-reactivity with non-target proteins. To reduce the time and cost of laboratory screening efforts for diagnostic reagents, we developed new methods for evaluating and selecting protein surface regions for ligand targeting.RESULTSWe devised combined structure- and sequence-based methods for identifying 3D epitopes and binding pockets on the surface of the A chain of ricin that are conserved with respect to a set of ricin A chains and unique with respect to other proteins. We (1) used structure alignment software to detect structural deviations and extracted from this analysis the residue-residue correspondence, (2) devised a method to compare corresponding residues across sets of ricin structures and structures of closely related proteins, (3) devised a sequence-based approach to determine residue infrequency in local sequence context and (4) modified a pocket-finding algorithm to identify surface crevices in close proximity to residues determined to be conserved/unique based on our structure- and sequence-based methods. In applying this combined informatics approach to ricin A, we identified a conserved/unique pocket in close proximity (but not overlapping) the active site that is suitable for bi-dentate ligand development. These methods are generally applicable to identification of surface epitopes and binding pockets for development of diagnostic reagents, therapeutics and vaccines.

AN - 68071368; 16019109 AB - Iodine is an important element in studies of environmental protection and human health, global-scale hydrologic processes and nuclear nonproliferation. Biogeochemical cycling of iodine is complex, because iodine occurs in multiple oxidation states and as inorganic and organic species that may be hydrophilic, atmophilic, and biophilic. In this study, we applied new analytical techniques to study the sorption and transport behavior of iodine species (iodide, iodate, and 4-iodoaniline) in sediments collected at the Savannah River and Hanford Sites, where anthropogenic (129)I from prior nuclear fuel processing activities poses an environmental risk. We conducted integrated column and batch experiments to investigate the interconversion, sorption and transport of iodine species, and the sediments we examined exhibit a wide range in organic matter, clay mineralogy, soil pH, and texture. The results of our experiments illustrate complex behavior with various processes occurring, including iodate reduction, irreversible retention or mass loss of iodide, and rate-limited and nonlinear sorption. There was an appreciable iodate reduction to iodide, presumably mediated by the structural Fe(II) in some clay minerals; therefore, careful attention must be given to potential interconversion among species when interpreting the biogeochemical behavior of iodine in the environment. The different iodine species exhibited dramatically different sorption and transport behavior in three sediment samples, possessing different physico-chemical properties, collected from different depths at the Savannah River Site. Our study yielded additional insight into processes and mechanisms affecting the geochemical cycling of iodine in the environment, and provided quantitative estimates of key parameters (e.g., extent and rate of sorption) for risk assessment at these sites.

The signal is complex, with a vertical structure that varies widely by ocean; it cannot be explained by natural internal climate variability or solar and volcanic forcing, but is well simulated by two anthropogenically forced climate models. We conclude that it is of human origin, a conclusion robust to observational sampling and model differences. Changes in advection combine with surface forcing to give the overall warming pattern. The implications of this study suggest that society needs to seriously consider model predictions of future climate change.

Dating caves is problematic, however, because their ages are only constrained by the oldest deposits contained within, which may be far younger than the cave itself. We dated cave deposits in the Sierra Nevada using U-Th dating of speleothems, paleomagnetic dating of fine sediment, and cosmogenic (super 26) Al/ (super 10) Be burial dating of coarse sediment. The sampled caves formed sequentially as the water table lowered, providing an important stratigraphic test for the dating methods. Large discrepancies between deposit ages from similar cave levels demonstrate that, even when accurately determined, deposit ages can seriously underestimate the timing of cave development. Drip-type speleothems are most prone to this minimum age bias because they can accumulate long after caves form, and because the U-Th method is limited to approximately 400 ka. Paleomagnetic dating requires correlation with the global reversal chronology, and is hindered by a lack of continuous stratigraphy. The fine sediment analyzed for paleomagnetism is also highly susceptible to remobilization and deposition in cave passages well above base level. Cosmogenic (super 26) Al/ (super 10) Be dates bedload material deposited when caves were at or very near river level, and can date material as old as approximately 5 Ma. In the Sierra Nevada, speleothem U-Th ages and sediment burial ages from the same cave levels differ by as much as an order of magnitude. These results suggest speleothem ages alone may significantly underestimate cave ages and thereby overestimate rates of landscape evolution. Cosmogenic burial dating of coarse clastic sediment appears to be the most reliable method for dating cave development in mountainous regions.

To help reconstruct the timing and extent of glaciation throughout Tibet and the bordering mountains, we use geomorphic mapping and (super 10) Be cosmogenic radionuclide (CRN) surface dating in study areas in southeastern (Gonga Shan), southern (Karola Pass) and central (Western Nyainqentanggulha Shan and Tanggula Shan) Tibet, and we compare these with recently determined numerical chronologies in other parts of the plateau and its borderlands. Each of the study regions receives its precipitation mainly during the south Asian summer monsoon when it falls as snow at high altitudes. Gonga Shan receives the most precipitation (>2000 mm a (super -1) ) while, near the margins of monsoon influence, the Karola Pass receives moderate amounts of precipitation (500-600 mm a (super -1) ) and, in the interior of the plateau, little precipitation falls on the western Nyainqentanggulha Shan ( approximately 300 mm a (super -1) ) and the Tanggula Shan (400-700 mm a (super -1) ). The higher precipitation values for the Tanggula Shan are due to strong orographic effects. In each region, at least three sets of moraines and associated landforms are preserved, providing evidence for multiple glaciations. The (super 10) Be CRN surface exposure dating shows that the formation of moraines in Gonga Shan occurred during the early-mid Holocene, Neoglacial and Little Ice Age, on the Karola Pass during the Lateglacial, Early Holocene and Neoglacial, in the Nyainqentanggulha Shan date during the early part of the last glacial cycle, global Last Glacial Maximum and Lateglacial, and on the Tanggula Shan during the penultimate glacial cycle and the early part of the last glacial cycle. The oldest moraine succession in each of these regions varies from the early Holocene (Gonga Shan), Lateglacial (Karola Pass), early Last Glacial (western Nyainqentanggulha Shan), and penultimate glacial cycle (Tanggula Shan). We believe that the regional patterns and timing of glaciation reflect temporal and spatial variability in the south Asian monsoon and, in particular, in regional precipitation gradients. In zones of greater aridity, the extent of glaciation has become increasingly restricted throughout the Late Quaternary leading to the preservation of old (>>100 ka) glacial landforms. In contrast, in regions that are very strongly influenced by the monsoon (>>1600 mm a (super -1) ), the preservation potential of pre-Lateglacial moraine successions is generally extremely poor. This is possibly because Lateglacial and Holocene glacial advances may have been more extensive than early glaciations and hence may have destroyed any landform or sedimentary evidence of earlier glaciations. Furthermore, the intense denudation, mainly by fluvial and mass movement processes, which characterize these wetter environments, results in rapid erosion and re-sedimentation of glacial and associated landforms, which also contributes to their poor preservation potential.

This parameterization accounts for the effects of building drag, turbulent production, radiation balance, anthropogenic heating, and building rooftop heating/cooling. U.S. Geological Survey (USGS) land-use data are also utilized to derive urban infrastructure and urban surface properties needed for driving the UCP. An intensive observational period with clear sky, strong ambient wind, and drainage flow, and the absence of a land-lake breeze over the Salt Lake Valley, occurring on 25-26 October 2000, is selected for this study. A series of sensitivity experiments are performed to gain understanding of the urban impact in the mesoscale model. Results indicate that within the selected urban environment, urban surface characteristics and anthropogenic heating play little role in the formation of the modeled nocturnal urban boundary layer. The rooftop effect appears to be the main contributor to this urban boundary layer. Sensitivity experiments also show that for this weak urban heat island case, the model horizontal grid resolution is important in simulating the elevated inversion layer. The root-mean-square errors of the predicted wind and temperature with respect to surface station measurements exhibit substantially larger discrepancies at the urban locations than their rural counterparts. However, the close agreement of modeled tracer concentration with observations fairly justifies the modeled urban impact on the wind-direction shift and wind-drag effects.

Because MTBE is very soluble in water, it is difficult to remove from solution by conventional remediation techniques, therefore, biodegradation of MTBE has become a remediation alternative. In order to understand the transport and transformation processes, in this paper, we present a closed form analytical solution, which can be applied as a screening tool. The possible reaction pathways of first-order reactions are described as a reaction matrix. The singular value decomposition is conducted analytically to decouple the partial differential equations of the multi-species transport system coupled by the reaction matrix into multiple independent subsystems. Therefore, the complexity of mathematical description for the reactive transport system is significantly reduced and the analytical expressions can be derived.

While Y. pestis and Yersinia pseudotuberculosis share more than 90% DNA homology, they have significantly different clinical manifestations. Plague is often fatal if untreated, yet Y. pseudotuberculosis causes severe intestinal distress but is rarely fatal. A better understanding of host response to these closely related pathogens may help explain the different mechanisms of virulence and pathogenesis that result in such different clinical outcomes. The aim of this study was to characterize host protein expression changes in human monocyte U937 cells after exposure to Y. pestis and Y. pseudotuberculosis. In order to gain global proteomic coverage of host response, proteins from cytoplasmic, nuclear and membrane fractions of host cells were studied by two-dimensional differential gel electrophoresis and relative protein expression differences were quantitated. Differentially expressed proteins, with at least 1.5-fold expression changes and p values of 0.01 or less, were identified by mass spectrometry including matrix-assisted laser desorption/ionization-MS or liquid chromatography tandem mass spectrometry. With these criteria, differential expression was detected in 16 human proteins after Y. pestis exposure and 13 human proteins after Y. pseudotuberculosis exposure, of which only two of the differentially expressed proteins identified were shared between the two exposures. Proteins identified in this study are reported to be involved in a wide spectrum of cellular functions and host defense mechanisms including apoptosis, cytoskeletal rearrangement, protein synthesis and degradation, DNA replication and transcription, metabolism, protein folding, and cell signaling. Notably, the differential expression patterns observed can distinguish the two pathogen exposures from each other and from unexposed host cells. The functions of the differentially expressed proteins identified provide insight on the different virulence and pathogenic mechanisms of Y. pestis and Y. pseudotuberculosis.

AN - 68095599; 16053543 AB - We have designed and demonstrated a standoff Raman system for detecting high explosive materials at distances up to 50 meters in ambient light conditions. In the system, light is collected using an 8-in. Schmidt-Cassegrain telescope fiber-coupled to an f/1.8 spectrograph with a gated intensified charge-coupled device (ICCD) detector. A frequency-doubled Nd : YAG (532 nm) pulsed (10 Hz) laser is used as the excitation source for measuring remote spectra of samples containing up to 8% explosive materials. The explosives RDX, TNT, and PETN as well as nitrate- and chlorate-containing materials were used to evaluate the performance of the system with samples placed at distances of 27 and 50 meters. Laser power studies were performed to determine the effects of laser heating and photodegradation on the samples. Raman signal levels were found to increase linearly with increasing laser energy up to approximately 3 x 10(6) W/cm2 for all samples except TNT, which showed some evidence of photo- or thermal degradation at higher laser power densities. Detector gate width studies showed that Raman spectra could be acquired in high levels of ambient light using a 10 microsecond gate width.

AN - 68077984; 16035041 AB - Paternally-transmitted chromosomal damage has been associated with pregnancy loss, developmental and morphological defects, infant mortality, infertility, and genetic diseases in the offspring, including cancer. There is epidemiological evidence linking paternal exposure to occupational or environmental agents with an increased risk of abnormal reproductive outcomes. There is also a large body of literature on germ cell mutagenesis in rodents showing that treatment of male germ cells with mutagens has dramatic consequences on reproduction, producing effects such as those observed in human epidemiological studies. However, we know very little about the etiology, transmission, and early embryonic consequences of paternally-derived chromosomal abnormalities. The available evidence suggests that: 1) there are distinct patterns of germ cell-stage differences in the sensitivity of induction of transmissible genetic damage, with male postmeiotic cells being the most sensitive; 2) cytogenetic abnormalities at first metaphase after fertilization are critical intermediates between paternal exposure and abnormal reproductive outcomes; and 3) there are maternal susceptibility factors that may have profound effects on the amount of sperm DNA damage that is converted into chromosomal aberrations in the zygote and that directly affect the risk for abnormal reproductive outcomes.

AN - 68035343; 16013717 AB - The American Association of Physicists in Medicine Task Group 43 reports, AAPM TG-43 and its update TG-43U1, provide an analytical model and a dosimetry protocol for brachytherapy dose calculations, as well as documentation and results for some sealed sources. The radionuclide 198Au (T(1/2)=2.70 days, Egamma=412 keV) has been used in the form of seeds for brachytherapy treatments including brain, eye, and prostate tumors. However, TG-43 reports have no data for 198Au seeds, and none have previously been obtained. For that reason, and because of the conversion of most treatment planning systems to TG-43 based methods, both Monte Carlo calculations (MCNP 4C2) and thermoluminescent dosimeters (TLDs) are used in this work to determine these data. The geometric variation in dose is measured using an array of TLDs in a solid water phantom, and the seed activity is determined using a high purity germanium detector (HPGe) and a well ionization chamber. The results for air kerma strength, Sk, per unit apparent activity, are 2.063 (MCNP) and 2.089 (measured) U mCi(-1), values close to those published in 1991 in the AAPM Task Group 32 report. The dose rate constant, lambda, is found equal to 1.115 (MCNP) and 1.095 (measured) cGy h(-1) U(-1). The radial dose function, g(r), anisotropy function, F(r, theta), and anisotropy factor, phi(an)(r), are also given.

In order to determine the age of the relatively younger fans, the erosion rate of the boulders and the cosmogenic nuclide inheritance from exposure prior to deposition in the fan were established. Cosmogenic nuclide inheritance values that range between 8.5X10 (super 3) and 196X10 (super 3) atoms (super 10) Be g (super -1) quartz were determined by measuring the concentrations and ratios of (super 10) Be and (super 26) Al in boulders (n = 10) and fine sediment (n = 7) at the outlet of the present active stream. Boulder erosion rate, ranging between 17 and 160 mm k.y. (super -1) , was estimated by measuring (super 10) Be and (super 26) Al concentrations in nearby bedrock outcrops (n = 8). Since the boulders on the fans represent the most resistant rocks in this environment, we used the lowest rate for the age calculations. Monte Carlo simulations were used to determine ages of 16+ or -5 and 29+ or -7 ka for the two younger fan surfaces. Older fans (older than 100 ka) were dated by analyzing (super 10) Be and (super 26) Al concentrations in buried sand samples. The ages of the three oldest fans range between 227+ or -242 and 413+ or -185 ka. Although fan age determinations are accompanied by large uncertainties, the results of this study show a clear trend of increasing fan ages with increasing distance from the source near Little Rock Creek and provide a long-term slip rate along this section of the San Andreas fault.Slip rate along the Mojave section of the San Andreas fault for the past 413 k.y. can be determined in several ways. The average slip rate calculated from the individual fan ages is 4.2+ or -0.9 cm yr (super -1) . A linear regression through the data points implies a slip rate of 3.7+ or -1.0 cm yr (super -1) . A most probable slip rate of 3.0+ or -1.0 cm yr (super -1) is determined by using a chi (super 2) test. These rates suggest that the average slip along the Mojave section of the San Andreas fault has been relatively constant over this time period. The slip rate along the Mojave section of the San Andreas fault, determined in this study, agrees well with previous slip rate calculations for the Quaternary.

LSMs have evolved from a leaky-bucket approximation to more sophisticated land surface water and energy budget models that typically have a specified bottom layer flux to depict the lowest model layer exchange with deeper aquifers. The LSM lower boundary is often assumed zero flux or the soil moisture content is set to a constant value; an approach that while mass conservative, ignores processes that can alter surface fluxes, runoff, and water quantity and quality. Conversely, groundwater models (GWMs) for saturated and unsaturated water flow, while addressing important features such as subsurface heterogeneity and three-dimensional flow, often have overly simplified upper boundary conditions that ignore soil heating, runoff, snow, and root-zone uptake. In the present study, a state-of-the-art LSM (Common Land Model) and a variably saturated GWM (ParFlow) have been coupled as a single-column model. A set of simulations based on synthetic data and data from the Project for Intercomparison of Land-surface Parameterization Schemes (PILPS), version 2(d), 18-yr dataset from Valdai, Russia, demonstrate the temporal dynamics of this coupled modeling system. The soil moisture and water table depth simulated by the coupled model agree well with the Valdai observations. Differences in prediction between the coupled and uncoupled models demonstrate the effect of a dynamic water table on simulated watershed flow. Comparison of the coupled model predictions with observations indicates certain cold processes such as frozen soil and freeze/thaw processes have an important impact on predicted water table depth. Comparisons of soil moisture, latent heat, sensible heat, temperature, runoff, and predicted groundwater depth between the uncoupled and coupled models demonstrate the need for improved groundwater representation in land surface schemes.

Our results show that Sr has complex behavior as an impurity. At low concentrations, Sr promotes faster growth. This effect may be associated with slight shifts in calcite solubility when Sr is incorporated or may be due to as yet uncharacterized kinetic effects. At higher concentrations, Sr stops step advancement by pinning kink-sites or step edges. The threshold concentration of Sr needed to halt growth is positively correlated with supersaturation. Addition of Sr to the calcite growth system leads to significant changes in hillock morphology. Hillocks become elongate perpendicular to the projection of the c-glide plane, in contrast to the changes previously reported for Mg. Step edges also become scalloped, and the boundary between the obtuse-stepped flanks disappears and is replaced by a new step direction with edges parallel to [010]. Incorporation of Sr was measured at two supersaturation levels and identical fluid [Sr]. The results indicate a strong positive correlation between fluid supersaturation and crystal Sr content. Further, Sr is strongly fractionated between obtuse- and acute-stepped flanks by a factor of approximately two. The sensitivity of Sr uptake to supersaturation may explain apparently contradictory results in the literature regarding whether Sr uptake in the calcite produced by one-celled marine organisms is controlled by temperature. In addition, Sr contents of natural calcite samples may be good indicators of the levels of supersaturation at which the crystals grew. Results of this investigation demonstrate the importance of understanding impurity-specific interactions with calcite growth surfaces at the microscopic scale. Despite similar chemical behavior in some systems, Mg and Sr clearly have very different effects on calcite growth. If Sr and other impurities are to be used as robust indicators of growth conditions in natural calcite samples, well grounded understanding of the mechanisms of recording trace element signatures in calcite is an essential step toward correctly deciphering paleoenvironmental signals from fossil calcite compositions.

Solution chemistry, condensed vapor chemistry, and precipitate mineralogy were used to identify important chemical divides and to validate geochemical calculations of evaporating water chemistry using a high temperature Pitzer thermodynamic database. The water evolved toward a complex "sulfate type" brine that contained about 45 mol % Na, 40 mol % Cl, 9 mol % NO (sub 3) , 5 mol % K, and less than 1 mol % each of SO (sub 4) , Ca, Mg, Sigma CO (sub 2) (aq), F, and Si. All measured ions in the condensed vapor phase were below detection limits. The mineral precipitates identified were halite, anhydrite, bassanite, niter, and nitratine. Trends in the solution composition and identification of CaSO (sub 4) solids suggest that fluorite, carbonate, sulfate, and magnesium-silicate precipitation control the aqueous solution composition of sulfate type waters by removing fluoride, calcium, and magnesium during the early stages of evaporation. In most cases, the high temperature Pitzer database, used by EQ3/6 geochemical code, sufficiently predicts water composition and mineral precipitation during evaporation. Predicted solution compositions are generally within a factor of 2 of the experimental values. The model predicts that sepiolite, bassanite, amorphous silica, calcite, halite, and brucite are the solubility controlling mineral phases.

NaCl, NaNO (sub 3) , and KNO (sub 3) represent members of dust salt assemblages that are likely to deliquesce and form concentrated brines on high-level radioactive waste package surfaces in a repository environment at Yucca Mountain, NV. Discrepancy between model prediction and experiment can be as high as 8% for relative humidity and 50% for dissolved ion concentration. The discrepancy is attributed primarily to the use of 25 degrees C models for Cl-NO (sub 3) and K-NO (sub 3) ion interactions in the current Yucca Mountain Project high-temperature Pitzer model to describe the nonideal behavior of these highly concentrated solutions.

It is therefore essential to evaluate the structure and mechanical properties of these altered dentins. One such altered form of dentin is transparent (sometimes called sclerotic) dentin, which forms gradually with aging. The present study focuses on differences in the structure and mechanical properties of normal versus transparent dentin. The mineral concentration, as measured by X-ray computed microtomography, was significantly higher in transparent dentin, the elevated concentration being consistent with the closure of the tubule lumens. Crystallite size, as measured by small angle X-ray scattering, was slightly smaller in transparent dentin, although the importance of this finding requires further study. The elastic properties were unchanged by transparency; however, transparent dentin, unlike normal dentin, exhibited almost no yielding before failure. In addition, the fracture toughness was lowered by roughly 20% while the fatigue lifetime was deleteriously affected at high stress levels. These results are discussed in terms of the altered microstructure of transparent dentin.

Natural sources of nitrate identified include microbially produced nitrate from the soil column ( delta super(15)N of 4-8ppt, delta super(18)O of -9 to 2ppt) and nitrate in buried caliche layers ( delta super(15)N of 0-8ppt, delta super(18)O of -6 to 42ppt). Isotopically distinct industrial sources of nitrate include nitric acid in low-level disposal waters ( delta super(15N) approximately 0ppt, delta super(18)O approximately 23ppt) and co-contaminant nitrate in high-level radioactive waste from plutonium processing ( delta super(15)N of 8-33ppt, delta super(18)O of -9 to 7ppt). The isotopic compositions of nitrate from 97 groundwater wells with concentrations up to 1290 mg/L NO sub(3) super(-) have been analyzed. Stable isotope analyses from this study site, which has natural and industrial nitrate sources, provide a tool to distinguish nitrate sources in an unconfined aquifer where concentrations alone do not. These data indicate that the most common sources of high nitrate concentrations in groundwater at Hanford are nitric acid and natural nitrate flushed out of the UZ during disposal of low-level wastewater. Nitrate associated with high-level radioactive UZ contamination does not appear to be a major source of groundwater nitrate at this time.

AN - 85397557; pmid-15957763 AB - Most diffraction tomography (DT) algorithms use a homogeneous Green function (GF) regardless of the medium being imaged. This choice is usually motivated by practical considerations: analytic inversions in standard geometries (Cartesian, spherical, etc.) are significantly simplified by the use of a homogeneous GF, estimating a nonhomogeneous GF can be very difficult, as can incorporating a nonhomogeneous GF into standard DT algorithms. Devaney has circumvented these issues by developing a purely numerical DT inversion algorithm [A. J. Devaney and M. Dennison, Inverse Probl. 19, 855-870 (2003)] that is independent of measurement system geometry, number of frequencies used in the reconstruction, and GF. A planar multilayer GF has been developed for use in Devaney's "Hilbert space" algorithm and used in a proof-of-principle nondestructive evaluation (NDE) experiment to image noninvasively a flaw in an aluminum/copper planar multilayer medium using data collected from an ultrasonic measurement system. The data were collected in a multistatic method with no beamforming: all focusing through the multilayer was performed mathematically "after-the-fact," that is, after the data were collected.

AN - 67960550; 15971410 AB - A group of heterocyclic amines that are mutagens and rodent carcinogens form when meat is cooked to medium and well-done states. The precursors of these compounds are natural meat components: creatinine, amino acids, and sugars. Defined model systems of dry-heated precursors mimic the amounts and proportions of heterocyclic amines found in meat. Results from model systems and cooking experiments suggest ways to reduce their formation and, thus, reduce human intake. Human cancer epidemiology studies related to the consumption of well-done meat products are listed and compared in this review.

Externally driven climate change has been detected by a number of investigators in independent data covering many parts of the climate system, including surface temperature on global and large regional scales, ocean heat content, atmospheric circulation, and variables of the free atmosphere, such as atmospheric temperature and tropopause height. The influence of external forcing is also clearly discernible in reconstructions of hemispheric-scale temperature of the last millennium. These observed climate changes are very unlikely to be due only to natural internal climate variability, and they are consistent with the responses to anthropogenic and natural external forcing of the climate system that are simulated with climate models. The evidence indicates that natural drivers such as solar variability and volcanic activity are at most partially responsible for the large-scale temperature changes observed over the past century, and that a large fraction of the warming over the last 50 yr can be attributed to greenhouse gas increases. Thus, the recent research supports and strengthens the IPCC Third Assessment Report conclusion that "most of the global warming over the past 50 years is likely due to the increase in greenhouse gases".

Here we report a detailed record of changes in moisture availability during the latter part of this transition ( approximately 11 250 to 7500 cal. yr BP) inferred from sediment cores retrieved in Lake Peten Itza, northern Guatemala. Pollen assemblages demonstrate that a mesic forest had been largely established by approximately 11 250 cal. yr BP, but sediment properties indicate that lake level was more than 35 m below modern stage. From 11 250 to 10 350 cal. yr BP, during the Preboreal period, lithologic changes in sediments from deep-water cores (>50 m below modern water level) indicate several wet-dry cycles that suggest distinct changes in effective moisture. Four dry events (designated PBE1-4) occurred centred at 11 200, 10 900, 10 700 and 10 400 cal. yr BP and correlate with similar variability observed in the Cariaco Basin titanium record and glacial meltwater pulses into the Gulf of Mexico. After 10 350 cal. yr BP, multiple sediment proxies suggest a shift to a more persistently moist early Holocene climate. Comparison of results from Lake Peten Itza with other records from the circum-Caribbean demonstrates a coherent climate response during the entire span of our record. Furthermore, lowland Neotropical climate during the late deglacial and early Holocene period appears to be tightly linked to climate change in the high-latitude North Atlantic. We speculate that the observed changes in lowland Neotropical precipitation were related to the intensity of the annual cycle and associated displacements in the mean latitudinal position of the Intertropical Convergence Zone and Azores-Bermuda high-pressure system. This mechanism operated on millennial-to-submillennial timescales and may have responded to changes in solar radiation, glacial meltwater, North Atlantic sea ice, and the Atlantic meridional overturning circulation (MOC).

We present a well-dated bi-decadal record of vegetation, climate, land use, and fire frequency from a tidal marsh in the Hudson River Estuary. The classic Medieval Warm Period is evident through striking increases in charcoal and Pinus dominance from approximately 800-1300 A.D., paralleling paleorecords southward along the Atlantic seaboard. Higher inputs of inorganic sediment during this interval suggest increased watershed erosion during drought conditions. The presence of the Little Ice Age ensues with increases in Picea and Tsuga, coupled with increasing organic percentages due to cooler, moister conditions. European impact is manifested by a decline in arboreal pollen due to land clearance, increased weedy plant cover (i.e., Ambrosia, Plantago, and Rumex), and an increase in inorganic particles to the watershed.

Model results indicate that the Chemehuevi Mountains are eroding at approximately 40 mm/ka, whereas the mountain-proximal bedrock pediment and the interpiedmont Sawtooth Range are eroding more slowly at 10-21 and 9.5 mm/ka, respectively. Implications for the large scale geological and climatic controls on the generation, transport and deposition of sediment in the Mohave Desert are discussed.

The collector is portable, samples air at 1220 L/min, provides 3-8 mL liquid sample, and has 70 W power consumption. The RI collector was selected for this unit following an evaluation of leading commercial aerosol collectors. The compact, multi-slit virtual impactor has an area of, and a pressure drop of 0.2 kPa at an inlet flow of 1220 L/min. The virtual impactor reported here concentrates the aerosols by a factor of four when the major to minor flow is adjusted to 4:1 ratio, but it has been field operated at a ratio of 8:1 when sampling at 2300 L/min. A preliminary evaluation of the RI-Lawrence Livermore National Laboratory collector was conducted to verify the unit has low pressure drop and can collect aerosols greater than, . A more detailed evaluation is needed to fully characterize the collector. This bio-aerosol collector has been incorporated in autonomous pathogen detection systems.

Assessment of potential environmental exposures, if any, requires accurate, precise and practical methods for the measurement of low concentrations of 226,228Ra. A method for the simultaneous measurement of 226,228Ra in marine sediments, biota and produced water at a sensitivity of 0.01 pCi/g using high-sensitivity, high-resolution gamma-spectrometry was subjected to an interlaboratory exercise using U.S. commercial laboratories to validate its accuracy, precision, robustness, and sample throughput. The prescribed method involves direct counting for solid samples and a simple Pb(133Ba,Ra)SO4 co-precipitation procedure for water samples followed by gamma-counting. Analytical results received from the participating laboratories were subjected to data analysis and statistical evaluation to validate the overall performance of the prescribed method. Relatively good precision and high accuracy of data were achieved when the participating laboratories followed the prescribed procedure closely. The consistency of results among laboratories was not correlated to the 226,228Ra concentrations in the samples. Most of the results that failed the acceptance criteria were either due to the absence of geometric and secular equilibrium between 226Ra and its signature decay daughters, or due to insufficient counting statistics when laboratories are working close to their detection limits. No significant bias or systematic errors were observed, except for produced water samples where results were biased high compared to the known values.

This method is based on the diffusion of radon gas into the gel material and the measurement of the radioactive daughters resulting from the radon decay. The 214Bi daughter gamma-ray, with an energy of 0.609 MeV, was chosen for these measurements, and the gamma-ray photopeak was analyzed via a HPGe multichannel system. The results indicate a linear relationship between the integrated area of the 214Bi photopeak and the concentration of radon that had diffused into the gel material. Two very well defined radon response levels were observed: (1) from 150 to 1500 Bq . m-3 and (2) from 1500 to 7400 Bq . m-3. This method gives highly reproducible and reliable results in the measurements of radon. This new technique opens the door to future studies of different gel materials in order to obtain better sensitivity and new applications in the measurement of radioactive gases.

In vertebrate organisms, distinct sequence elements mediate transcriptional regulation and are scattered throughout the genome, either proximal or distal to promoters. The identification of transcriptional enhancers has proven rather difficult by conventional experimental approaches. In the past decade, the rapid generation of genomic sequences for multiple vertebrate organisms, accompanied by sophisticated comparative tools, has facilitated the identification of non-coding evolutionarily conserved regions that may encode cis-regulatory elements. Validating computational predictions and characterising cis-regulatory elements in vivo, however, has been a major bottleneck, mainly because the most commonly used organism for these experiments has been the mouse, and generating transgenic mice or modifying the mouse genome continues to be a labour-intensive, low-throughput, expensive process. This has led to the use of Xenopus, which holds great promise for high-throughput interrogation of putative cis-regulatory elements. In particular, Xenopus tropicalis may become particularly powerful for elucidating regulatory networks, chiefly because it is amenable to genetic manipulations, and its genome is being sequenced.

AN - 67816958; 15884356 AB - Manganese oxides, present as minor phases in the vadose zone, have been previously shown to sequester large quantities of plutonium under environmental conditions. We are now continuing these studies with Np(V). Sorption onto manganite (MnOOH) and hausmannite (Mn3O4) at solid-to-solution ratios of 2.5-3.3 mg/mL has been studied as a function of neptunium concentration and pH. The sorption of Np increased as a function of pH for both minerals, attaining a maximum at neutral pH, and then decreased with increasing alkalinity. X-ray absorption fine structure spectroscopy (XAFS), taken at the Np L(III)-edge, has been used to determine the oxidation state of the sorbed Np. Our experimental results indicate reduction of the Np(V) because of interaction with the X-ray beam.

AN - 67481654; 15741059 AB - We have developed and tested a fully autonomous pathogen detection system (APDS) capable of continuously monitoring the environment for airborne biological threat agents. The system was developed to provide early warning to civilians in the event of a bioterrorism incident and can be used at high profile events for short-term, intensive monitoring or in major public buildings or transportation nodes for long-term monitoring. The APDS is completely automated, offering continuous aerosol sampling, in-line sample preparation fluidics, multiplexed detection and identification immunoassays, and nucleic acid-based polymerase chain reaction (PCR) amplification and detection. Highly multiplexed antibody-based and duplex nucleic acid-based assays are combined to reduce false positives to a very low level, lower reagent costs, and significantly expand the detection capabilities of this biosensor. This article provides an overview of the current design and operation of the APDS. Certain sub-components of the ADPS are described in detail, including the aerosol collector, the automated sample preparation module that performs multiplexed immunoassays with confirmatory PCR, and the data monitoring and communications system. Data obtained from an APDS that operated continuously for 7 days in a major U.S. transportation hub is reported.

AN - 85380075; pmid-15898625 AB - Laboratory experiments on wave propagation through saturated and partially saturated porous media have often been conducted on porous cylinders that were initially fully saturated and then allowed to dry while continuing to acquire data on the wave behavior. Since it is known that drying typically progresses from outside to inside, a sensible physical model of this process is concentric cylinders having different saturation levels-the simplest example being a fully dry outer cylindrical shell together with a fully wet inner cylinder. We use this model to formulate the equations for wave dispersion in porous cylinders for patchy saturation (i.e., drainage) conditions. In addition to multiple modes of propagation obtained numerically from these dispersion relations, we find two distinct analytical expressions for torsional wave modes. We solve the resulting torsional wave dispersion relation for two examples: Massillon sandstone and Sierra White granite. One essential fact that comes to light during the analysis is that the effective shear moduli of the gas- and liquid-saturated regions must differ, otherwise it is impossible to account for the laboratory torsional wave data. Furthermore, the drainage analysis appears to give improved qualitative and quantitative agreement with the data for both of the materials considered.

AN - 60705884; 200517255 AB - The effectiveness of Western programs designed to prevent Russian scientists from selling their knowledge about constructing weapons of mass destruction to rogue states is evaluated. An overview of circumstances that prompted former Soviet scientists to advertise their knowledge of weapons of mass destruction & of existing Western grant & nonproliferation programs that provide assistance to Russian scientists is provided. Interviews with Russian scientists (N = 602) employed at sundry biological, chemical, & physical research laboratories were conducted to ascertain their willingness to cooperate with authoritarian & democratic governments & foreign corporations to participate in weapons of mass destruction & dual-use technology development. An overwhelming majority of respondents indicated that no circumstances should encourage Russian scientists to conduct weapons of mass destruction or dual-use research for authoritarian or democratic states; however, approximately 31% of the participants stated they would perform such work for foreign companies if they received adequate compensation & found their tasks to be scientifically interesting.

Glaciers reached their greatest extent in the last glacial cycle approximately 34,000 years before the present and were retreating by approximately 21,000 years before the present, implying that tropical controls on ice volumes were asynchronous with those in the Northern Hemisphere. Our estimates of snowline depression reflect about half the temperature change indicated by previous widely cited figures, which helps resolve the discrepancy between estimates of terrestrial and marine temperature depression during the last glacial cycle.

Pore fluids can increase the magnitude of shear energy stored in this modulus by an amount that ranges from the smallest to the largest effective shear moduli of the VTI system. But since there are five shear moduli in play, the overall increase in shear energy due to fluids is reduced by a factor of about five in general. We can, therefore, give definite bounds on the maximum increase of overall shear modulus -- about 20% of the allowed range as liquid is fully substituted for gas. An attendant increase of density (depending on porosity and fluid density) by approximately 5-10% decreases the shear-wave speed and thereby partially offsets the effect of this shear modulus increase. The final result is an increase of shear-wave speed on the order of 5-10%. This increase is shown to be possible under most favorable circumstances, that is, when the shear modulus fluctuations are large (resulting in strong anisotropy) and the medium behaves in an undrained fashion due to fluid trapping. At frequencies higher than seismic (such as sonic and ultrasonic waves for well logging or laboratory experiments), resulting short response times also produce the requisite undrained behavior; therefore, fluids also affect shear waves at high frequencies by increasing rigidity.

Although the mineralogy and petrography of these CAIs have been reported previously, the relict chondrule inclusions were not found. By contrast, with one exception all CAI-chondrule compound objects consist of relict CAIs inside chondrules, indicating that the host chondrules formed by melting of solid precursors containing pre-existing CAIs. Elemental maps and back-scattered electron micrographs illustrate the chemistry and mineralogy of these two CAIs which are described in detail. The relict chondrule is composed of olivine and low-Ca pyroxene, is (super 16) O-poor and occurs in the outer part of TS26 containing Cr-rich, Al-Ti-poor diopside which partly replaces the olivine-pyroxene relict, and is surrounded by haloes of high-Ca pyroxene. The corroded texture of olivine-pyroxene chondrule relicts in the two CAIs, indicates that the grains were present inside the CAI hosts during their final crystallization and were partly dissolved in the CAI melt. It is suggested that ABC and TS26 experienced incomplete oxygen isotopic exchange and dilution with (super 16) O-poor relict chondrule material during their last melting in a (super 16) O-poor gas - probably in the chondrule-forming region. Relict chondrule-like material in the outer part of TS26 indicates abundant dust in the region of melting consistent with the dusty environment postulated for chondrule formation.

Ion-microprobe mass spectrometry is capable of producing Th ionization efficiencies in excess of 2%. Analytical precision is typically better than alpha spectroscopy, but not as good as thermal ionization mass spectroscopy (TIMS) and inductively coupled plasma multicollector mass spectrometry (ICP-MS). Like TIMS and ICP-MS the method allows analysis of small samples sizes, but also adds the advantage of rapidity of analysis. A major advantage of ion-microprobe analysis is that U and Th isotopes are analyzed in the same bead, simplifying the process of chemical separation. Analytical time on the instrument is approximately 60 min per sample, and a single instrument-loading can accommodate 15-20 samples to be analyzed in a 24-h day. An additional advantage is that the method allows multiple reanalyses of the same bead and that samples can be archived for reanalysis at a later time. Because the ion beam excavates a pit only a few mu m deep, the mount can later be repolished and reanalyzed numerous times. The method described of preconcentrating a low concentration sample onto a small conductive substrate to allow ion-microprobe mass spectrometry is potentially applicable to many other systems.

Over these experimental conditions, labradorite dissolution can be described with a single rate expression that accounts for observed increases in dissolution rate with increasing temperature and decreases in dissolution rate with increasing dissolved aluminum: (A1)Si Rate(mol Labradorite cm (super -2) s (super -1) ) = kX10 (super -Ea/2.303RT) [(a (sub H+) (super 3n) /a (sub Al3+) (super n) )K (sub T) /(1+K (sub T) (a (sub H+) (super 3n) /a (sub Al3+) (super n) ))](Al) where the apparent dissolution rate constant, k = 10 (super -5.69) (mol Labradorite cm (super -2) s (super -1) ) and the net activation energy, E (sub a) = 10.06 (kcal mol (super -1) ). This temperature-dependent rate expression is partly based on the model proposed by Oelkers et al. (1994) [Oelkers, E. H., Schott, J., Devidal, J., 1994. The effect of aluminum, pH, and chemical affinity on the rates of aluminosilicate dissolution reactions. Geochim. Cosmochim. Acta, 58, 2011-2024.] in which the dependence of silicate dissolution rates on dissolved aluminum in acidic solutions is attributed to H (super +) -Al (super 3+) exchange at the mineral surface and formation of silica-rich surface complexes. For this exchange reaction, regression of the experimental data yield a stoichiometric coefficient n=0.31 and an enthalpy of reaction Delta H = 0.54 (kcal mol (super -1) ). The temperature dependence of the silica-rich surface complex formation constant, K (sub T) , was estimated from the van't Hoff equation and yielded K (sub T) = 4.49 to 5.61 from 30 to 130 degrees C. Elevated CO (sub 2(aq)) concentrations enhance mineral dissolution indirectly by acidifying solution pH. At temperatures below 100 degrees C, labradorite dissolves incongruently with preferential dissolution of Na, Ca, and Al over Si.

One possible approach is to sequester less-pure CO (sub 2) waste streams that are less expensive or require less energy to separate from flue gas or a coal gasification process, etc. The objective of this research is to evaluate the impacts of CO (sub 2) itself, as well as an impure CO (sub 2) waste stream, on geologic sequestration using reaction progress models, reactive transport simulators and analogous reactive transport experiments run in a plug flow reactor. Specifically, we are investigating the potential for co-injecting the SO (sub x) , NO (sub x) , and H (sub 2) S present in coal-fired waste streams along with the CO (sub 2) . We present here the results of reactive transport simulations made to investigate the long-term impact of dissolved CO (sub 2) , H (sub 2) S and SO (sub 2) on carbon sequestration in the Frio Fm., TX. The results suggest that addition of relatively large amounts of H (sub 2) S to a CO (sub 2) injection should not adversely impact injectivity or sequestration compared to the injection of CO (sub 2) alone. The co-injection of SO (sub 2) , however, could produce significantly different results, if conditions are such that SO (sub 2) can oxidize to sulfate. In the long-term the simulations suggest that carbonate mineral formation can sequester a significant fraction of the injected carbon through the formation of calcite, magnesite and dawsonite.

As part of that study, the regional geology and structure of the basin and surrounding area were evaluated to understand the development and structural framework of the basin and how basin development affected stratigraphy and groundwater flow. The Livermore Valley formed between the southward movement of Mt. Diablo and the northward movement of the Diablo Range. The Diablo Range exerted the primary control on the structure and stratigraphy in the Livermore Basin. Large north flowing streams from the Diablo Range contributed the majority of groundwater basin sediments. The northward range movement created oblique slip and thrust faults within the southern part of the basin. Development of these faults controlled stream and groundwater flow patterns within the basin. The southward growth of the Mt. Diablo frontal thrusts overrode the northern part of the original Livermore basin but created few structures within the remaining basin. Mt. Diablo was not a significant source of basin sediments. The primary effect of Mt. Diablo growth was the deflection, blocking, and rerouting of the streams that flowed north out of the Diablo Range.

This study identifies a typically unrecognized nitrate contamination risk of enhanced recharge of surface water through groundwater management activities. Augmented recharge can mobilize nitrate sources that would not affect the regional aquifer under natural, low recharge-rate conditions. An investigation of a nitrate contaminated groundwater basin in Livermore, California, demonstrates that nitrate isotope data are effective in determining contaminant sources, and that other isotopic tracers such as oxygen isotopes and tritium-helium ages give insight into the routes and timing of nitrate inputs to the flow system. Low nitrate reclaimed wastewater predominates in the northwest, while two flowpaths with distinct nitrate sources originate in the southeast. Along the eastern flowpath delta (super 15) N values greater than 10 per mil indicate that animal waste is the primary source. Diminishing concentrations over time suggest that nitrate contamination results from historical land use practices. The other flowpath begins in an area where rapid recharge, primarily of low-nitrate imported water (identified by stable isotopes of water and a tritium-helium residence time of less than 1 year), mobilizes a significant local nitrate source, bringing groundwater concentrations up to 53 mg/L. In this area, artificial recharge of State Project water via local arroyos induces a flux of the contaminant to the regional aquifer. The low delta (super 15) N (3.1 per mil) value in this location implicates synthetic fertilizer, although nitrification in the root zone of natural vegetation is another likely contributor. Geochemical modeling supports the hypothesis of separate sources, one including organic carbon, as from animal waste, and one not. In addition to these anthropogenic sources, natural nitrate background levels between 15 and 20 mg/L are found in deep wells with residence times greater than 50 years. This work was performed under the auspices of the U.S. Department of Energy by the University of California, Lawrence Livermore National Laboratory under Contract W-7405-Eng-48.

The earlier time is marked by formation of large sedimentary basins, low-angle normal faulting, and prominent strike-slip faulting. About or after 5.5 Ma, extension rate slowed and new basins formed. These basins are controlled by mostly high-angle normal faults. We suggest that the difference results from changes in the plate boundary to the W and a localization of deformation onto large segmented normal faults to the E. Las Vegas basin (LVB), in the central CBR, exemplifies the changes in tectonism through time. LVB contains up to approximately 5 km of Neogene sediments based on data from approximately 1150 wells <1 km deep and 6 deep wells The approximately 18-5.5 Ma basin was formed by three main faults. (1) The Las Vegas Valley shear zone (LVVSZ) has approximately 50 km of right slip, approximately 2.5 km of down-on-the-S dip slip and forms the northern basin margin. (2) The FMF, along the E side of the basin, has approximately 6 km of down-on-the-W dip slip, but some slip is post-5.5 Ma. (3) A fault under the basin that generates major paleorelief. 25 wells record the sub-Pliocene unconformity and show that approximately 2/3 of the basin-fill is Miocene. The <5.5 Ma basin has less dramatic paleorelief along its base, and is broader and more symmetric than the approximately 18-5.5 Ma basin. The deepest part of the younger basin lies W of that of the older basin. The geometry of the younger basin also is created by the FMF on the E and the inactive, but topographically significant LVVSZ on the N. The shape difference and shift in the depocenter was caused by three E-dipping faults, with scarps, exposed near the basin center. Thus, LVB is a composite basin with structural controls that change through time. Comparison of available timing data on these <5.5 Ma faults with other young faults in the region suggest that they were active synchronously with (1) strike-slip faults in the southern Walker Lane and the Eastern California shear zone to the W and (2) high-angle normal faults along the eastern edge of the CBR. Those strike-slip faults accommodate the step-over of some plate boundary slip from the San Andreas to the east side of the Sierra Nevada. The normal faults along the eastern side of the CBR (e.g., Hurricane and Sevier faults) linked to form long, discrete structures during this time. Thus, the <5.5 Ma faults in LVB appear to accommodate a change in shape of the volume of rock between these strike-slip and normal faults.

The study area included the western part of the chain-of-lakes area. Of specific interest was the Lake I area, considered a significant basin recharge area. The objective of the investigation was to evaluate the hydrostratigraphy and aquifer architecture in the Lake I area to assess the effectiveness of the surface to groundwater recharge into deeper groundwater aquifers that are used for municipal supply by Zone 7. By evaluating subsurface data using sequence stratigraphy, the geometry and distribution of aquifer and aquitard sediments are linked to the original depositional processes that formed the sediments. The sequence stratigraphic study proved to be valuable in assessing groundwater flow and the effectiveness of groundwater recharge in the Lake I area. Four stratigraphic sequences were identified based on the analysis of (1) outcrop data at Lake I, (2) approximately 40 well logs (including both geophysics and lithologic descriptions), and (3) groundwater elevation data. Four generalized lithofacies were identified in the study area based primarily on geophysical log character tied to lithologic descriptions of cuttings. Each sequence is marked by a sequence boundary at the base of a series of fining upward braided fluvial channels containing sand and gravel with interstratified flood plain and lacustrine clays and silts. Each sequence is capped by a laterally extensive lacustrine interval. The laterally extensive lacustrine intervals in concert with the subtle angular discordances between the sequences appear to be the controlling features to groundwater flow in this area of the basin.

Pratt, renown geologist and oil finder, at the regional meeting of AAPG in Austin, TX in October 1951. If this statement is true, then Thomas C. Chamberlin's classic and benchmark paper entitled "The Method of Multiple Working Hypotheses", published in the Journal of Geology in 1897, has application and use today in the discovery and development of oil and gas fields. The re-development of two gas fields in the Sacramento Valley, Grimes and Denverton Creek, began years after their discovery and relates to the principles set forth in Chamberlin's paper when applied to new and advanced geophysical and geological techniques and methods in field recovery. The Sacramento Valley was established as a natural dry gas producing basin in 1933 with the discovery of the Sutter Buttes field located west of the town of Marysville in Sutter County. To date the Valley has produced 9.6 trillion cubic feet of gas (CFG)and current production totals 190 million cubic feet of gas per day (CFGD) from 1000 wells in approximately 86 fields. Gas is produced from sands ranging in geologic age from upper Cretaceous to Recent, however, the primary producing sands are of Eocene, Paleocene and upper Cretaceous age. Gas entrapment is caused by a variety of stratigraphic, structural and erosional features. The Grimes field is located in Sutter and Colusa Counties and was discovered in 1960. The field has produced 650 billion CFG and is the third largest dry gas field in the state. Current field production is 10.4 million CFGD from 103 wells. The Denverton Creek field is located in Solano County and was discovered in 1966. The field has produced 39.6 billion CFG and currently produces 1.3 million CFGD from 8 wells. Even today, the successful and economic recovery of gas reserves in both fields is ongoing and these efforts echo the validity of the words of Pratt and Chamberlin.

The frequency of explosives tests involving tritium and depleted uranium peaked from the mid-1960s to early 1970s, when two 10-to 20-foot deep, unlined and uncapped landfills (Pits 3 and 5) received experimental debris. The landfills are incised into valley-fill alluvium and decomposed bedrock containing a shallow, ephemeral water-bearing zone that thickens and inundates landfill waste during high intensity rainfall events. The inventory was conducted for a CERCLA Remedial Investigation/Feasibility Study to characterize contaminants in soil, rock, and ground water. This inventory included 3-D visualization and property modeling to integrate a variety of independent data sets to determine the spatial relationship between residual contaminant sources and the rising and falling water table. Cone penetrometer friction and dipole-dipole resistivity data defined the depth of each pit. Refraction seismic and hydrogeologic data were used to identify the base of the shallow water-bearing zone. This basal surface was incorporated into a hydrogeologic framework model to determine the extent of pit inundation during the 1998 El Nino. Property modeling of soil and ground water chemical data was used to determine the 3-D distribution of tritium and depleted uranium remaining in the pits and surrounding soil and ground water. The highest activities of depleted uranium and tritium were co-located in samples collected near the bottom of Pit 3. The distribution of tritiogenic 3He in soil gas exhibited good spatial correlation with elevated soil moisture tritium. Determination of uranium isotopic composition by mass spectrometry allowed quantitation of depleted uranium activity in a geologic setting where high levels of natural uranium have been observed. Depleted uranium behaves non-conservatively and is restricted to the immediate vicinity of the pits, whereas tritium, a conservative tracer, has migrated thousands of feet in shallow alluvial and deeper bedrock aquifers. The preferred remedy proposed in the RI/FS includes a drainage diversion system that will divert recharge water away from the pits, minimizing pit inundation and contaminant releases during rainfall events.

We have found strong correlations between basin depth reported in the USGS 3D seismic velocity model (ver. 2) and different relative measures of ground motion parameters such as teleseismic arrival delays, P-wave amplitudes, wave energy, local earthquake S-wave amplitudes, and periods of microseism horizontal to vertical spectral ratio peaks. The teleseismic, local earthquake, and microseism observations were also found to be strongly correlated with one another. The results suggested that all three datasets are sensitive to the basin structure and could therefore be used to improve the 3D velocity model. We started to develop a simultaneous inversion of the teleseismic, local, and microseism observations to refine the present seismic velocity model. We use a 3D elastic finite-difference code to simulate the teleseismic, local, and microseism wavefields. The inversions are performed in the 0.1 to 1.0 Hz passband in which the SCV seismic experiment observations had a good signal to noise ratio. We will present preliminary results that invert for the velocity structure within the basins, while the basin geometry as defined in the USGS velocity model is held fixed.

In this paper we investigate the sensitivity of this feedback for year 2100 global warming in the range of 0 to 8 K. Differing climate sensitivities to increased CO sub(2) content are imposed on the carbon cycle models for the same emissions. Emissions from the SRES A2 scenario are used. We use a fully coupled climate and carbon cycle model, the INtegrated Climate and CArbon model (INCCA), the NCAR-DOE Parallel Climate Model coupled to the IBIS terrestrial biosphere model and a modified OCMIP ocean biogeochemistry model. In our integrated model, for scenarios with year 2100 global warming increasing from 0 to 8 K, land uptake decreases from 47% to 29% of total CO sub(2) emissions. Due to competing effects, ocean uptake (16%) shows almost no change at all. Atmospheric CO sub(2) concentration increases are 48% higher in the run with 8 K global climate warming than in the case with no warming. Our results indicate that carbon cycle amplification of climate warming will be greater if there is higher climate sensitivity to increased atmospheric CO sub(2) content; the carbon cycle feedback factor increases from 1.13 to 1.48 when global warming increases from 3.2 to 8 K.

AN - 67563840; 15798267 AB - The aim of this project is to extend accurate and patient-specific treatment planning to new treatment modalities, such as molecular targeted radiation therapy, incorporating previously crafted and proven Monte Carlo and deterministic computation methods. A flexible software environment is being created that allows planning radiation treatment for these new modalities and combining different forms of radiation treatment with consideration of biological effects. The system uses common input interfaces, medical image sets for definition of patient geometry and dose reporting protocols. Previously, the Idaho National Engineering and Environmental Laboratory (INEEL), Montana State University (MSU) and Lawrence Livermore National Laboratory (LLNL) had accrued experience in the development and application of Monte Carlo based, three-dimensional, computational dosimetry and treatment planning tools for radiotherapy in several specialized areas. In particular, INEEL and MSU have developed computational dosimetry systems for neutron radiotherapy and neutron capture therapy, while LLNL has developed the PEREGRINE computational system for external beam photon-electron therapy. Building on that experience, the INEEL and MSU are developing the MINERVA (modality inclusive environment for radiotherapeutic variable analysis) software system as a general framework for computational dosimetry and treatment planning for a variety of emerging forms of radiotherapy. In collaboration with this development, LLNL has extended its PEREGRINE code to accommodate internal sources for molecular targeted radiotherapy (MTR), and has interfaced it with the plugin architecture of MINERVA. Results from the extended PEREGRINE code have been compared to published data from other codes, and found to be in general agreement (EGS4-2%, MCNP-10%) (Descalle et al 2003 Cancer Biother. Radiopharm. 18 71-9). The code is currently being benchmarked against experimental data. The interpatient variability of the drug pharmacokinetics in MTR can only be properly accounted for by image-based, patient-specific treatment planning, as has been common in external beam radiation therapy for many years. MINERVA offers 3D Monte Carlo-based MTR treatment planning as its first integrated operational capability. The new MINERVA system will ultimately incorporate capabilities for a comprehensive list of radiation therapies. In progress are modules for external beam photon-electron therapy and boron neutron capture therapy (BNCT). Brachytherapy and proton therapy are planned. Through the open application programming interface (API), other groups can add their own modules and share them with the community.

However, when these & similar sensors are used in front of the laryngeal region during voiced speech, there remains an uncertainty regarding the contributions to the sensor signal from vocal fold movements versus those from pressure induced trachea-wall movements. Several signal-source hypotheses are tested by performing experiments with a subject who had undergone tracheostomy, & who still was able to phonate when her stoma was covered (e.g., with a plastic plate). Laser-doppler motion-measurements of the subject's posterior trachea show small tissue movements, about 15 microns, that do not contribute significantly to signals from presently used EM sensors. However, signals from the anterior wall do contribute. EM sensor & air-pressure measurements, together with 3-D EM wave simulations, show that EM sensors measure movements of the vocal folds very well. The simulations show a surprisingly effective guiding of EM waves across the vocal fold membrane, which, upon glottal opening, are interrupted & reflected. These measurements are important for EM sensor applications to speech signal de-noising, vocoding, speech recognition, & diagnostics.

AN - 67703033; 15754381 AB - The father, like the mother, can transmit genetic defects to his offspring that are detrimental for normal development and a healthy life. Epidemiological studies have identified associations between several paternal exposures and abnormal reproductive outcomes, but these types of studies are inherently complex and expensive, and the risk factors for the paternal contribution to abnormal reproductive outcomes remain poorly understood. Several sensitive methods have been developed for detecting mutations and chromosomal damage directly in sperm. These assays are potential bioindicators for paternal risk factors for infertility, spontaneous abortions, aneuploidy syndromes, and genetic diseases in children. Among these methods, fluorescence in situ hybridization (FISH) has been adapted for the detection of numerical and structural chromosomal abnormalities in the sperm of an expanding number of species, including humans and rodents. Sperm FISH has identified several potential paternal risk factors such as age, drugs, lifestyles, and various environmental/occupational exposures. Here, we summarize the status of the development and usage of these sperm-FISH assays and suggest strategies for prioritizing chemical agents for epidemiological investigations to assess paternal risk for abnormal reproductive outcome.

Here we report the first high precision measurements of (super 87) Sr/ (super 86) Sr by ion microprobe in calcium carbonate samples with moderate Sr concentrations. We use the high mass resolving power (7000 to 9000 M.R.P.) of the SHRIMP-RG ion microprobe in combination with its high transmission to reduce the number of interfering species while maintaining sufficiently high count rates for precise isotopic measurements. The isobaric interferences are characterized by peak modeling and repeated analyses of standards. We demonstrate that by sample-standard bracketing, (super 87) Sr/ (super 86) Sr ratios can be measured in inorganic and biogenic carbonates with Sr concentrations between 400 and 1500 ppm with approximately 2 per mil external precision (2sigma ) for a single analysis, and subpermil external precision with repeated analyses. Explicit correction for isobaric interferences (peak-stripping) is found to be less accurate and precise than sample-standard bracketing. Spatial resolution is approximately 25 mu m laterally and 2 mu m deep for a single analysis, consuming on the order of 2 ng of material. The method is tested on otoliths from salmon to demonstrate its accuracy and utility. In these growth-banded aragonitic structures, one-week temporal resolution can be achieved. The analytical method should be applicable to other calcium carbonate samples with similar Sr concentrations.

Between 1400 and 1500 A.D., oxygen isotope ratios of ostracod and gastropod carbonate increased by an average of 2.2 per mil and the benthic foraminifer Ammonia beccarii parkinsoniana appeared in the sediment profile, indicating a hydrologic change that included increased lake water salinity. Pollen from a core in nearby Cenote San Jose Chulchaca showed a decrease in mesic forest taxa during the same period. Oxygen isotopes of shell carbonate in sediment cores from Lakes Chichancanab (19 degrees 53.0'N, 88 degrees 46.0'W) and Salpeten (16 degrees 58.6'N, 89 degrees 40.5'W) to the south also increased in the mid-15th century, but less so than in Aguada X'caamal. Climate change in the 15th century is also supported by historical accounts of cold and famine described in Maya and Aztec chronicles. We conclude that climate became drier on the Yucatan Peninsula in the 15th century A.D. near the onset of the Little Ice Age (LIA). Comparison of results from the Yucatan Peninsula with other circum-Caribbean paleoclimate records indicates a coherent climate response for this region at the beginning of the LIA. At that time, sea surface temperatures cooled and aridity in the circum-Caribbean region increased.

We show that in order to estimate magmatic helium (He) contributions it is critical to simultaneously consider He isotopic ratios, He concentrations, and mixing of He components. Our component mixing analysis requires consideration of all measured noble gases but no other elements and is particularly insightful when strong dilution by air-saturated water has occurred. In addition, this approach can allow distinction between crustal and magmatic He components and facilitates their identification in deep groundwaters that have been diluted by near-surface water. Using this approach, we show that some cold springs on the eastern flanks of the Oregon Cascades exhibit He isotopic ratios that indicate significant magmatic He contributions comparable to those observed in thermal springs on the western flanks. Furthermore, while these magmatic He contributions are largest in deep groundwaters near the Cascades crest, greater magmatic excess He fractions than may be inferred from He isotopic ratios alone are present in all (deep) groundwaters including those at larger distances (>70 km) from the volcanic arc. We also suggest that excess He and heat discharge without dilution by air-saturated water may be restricted to spring discharge along faults.

This raises concerns that cancer survivors who were treated before or during their reproductive years may be at increased risks for abnormal reproductive outcomes. However, the available data from offspring of cancer survivors are limited, representing diverse cancers, therapies, time to pregnancies, and reproductive outcomes. Rodent breeding data after paternal exposures to individual chemotherapeutic agents illustrate the complexity of factors that influence the risk for transmitted genetic damage including agent, dose, end point, and germ cell susceptibility profiles that vary across agents. Direct measurements of chromosomal abnormalities in sperm of mice and humans by sperm fluorescent in situ hybridization have corroborated the differences in germ cell susceptibilities. The available evidence indicates that the risk of producing chromosomally defective sperm is highest during the first few weeks after the end of chemotherapy and decays with time. Thus, sperm samples provided immediately after the initiation of cancer therapies may contain treatment-induced genetic defects that will jeopardize the genetic health of offspring.

In previous studies, UGT1A1 has been implicated in the detoxification of certain food-borne carcinogenic-heterocyclic amines. To determine the importance of UDP-glucuronosyltransferase 1A1 (UGT1A1) in the biotransformation of the cooked-food carcinogen 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP), genetically modified CHO cells that are nucleotide excision repair-deficient, and express cytochrome P4501A2 (UV5P3 cell line) were transfected with a cDNA plasmid of human UGT1A1 to establish the UDP-glucuronosyltransferase 1A1 expressing 5P3hUGT1A1 cell line. Expression of the UGT1A1 gene was verified by screening neo gene expressing clonal isolates (G-418 resistant) for their sensitivity to cell killing from PhIP exposure. Five of 11 clones were chosen for further analysis due to their resistance to cell killing. Western blot analysis was used to confirm the presence of the UGT1A1 and CYP1A2 proteins. All five clones displayed a 52-kDa protein band, which corresponded to a UGT1A1 control protein. Only four of the clones had a protein band that corresponded to the CYP1A2 control protein. Correct fragment size of the cDNAs in the remaining four clones was confirmed by RT-PCR and quantification of the mRNA product was accomplished by real-time RT-PCR. Expression of UGT1A1 in the transfected cells was 10 super(4)-10 super(5)-fold higher relative to the UV5P3 parental cells. One clone (#14) had a 10-fold higher increase in expression at 1.47x10 super(5) over the other three clones. This clone was also the most active in converting N-hydroxy-PhIP to N-hydroxy-PhIP glucuronide conjugates in microsomal metabolism assays. Based on the D sub(5) sub(0) values, the cytotoxic effect of PhIP was decreased similar to 350-fold in the 5P3hUGT1A1 cells compared to the UV5P3 control cells. In addition, no significant increase in mutation frequency was observed in the transfected cells.

The model strives to represent the complexity of intertwining factors that determine the spatio-temporal dynamics of small rodents. It is based on trophic relationships and incorporates important features such as territorial competition, mating behavior, density-dependent predation and dispersal out of the modeled spatial region. Vegetation growth and vole fecundity are dependent on climatic components. The results of simulations show that the model correctly predicts the overall temporal dynamics of the population density. Time-series analysis shows a very good match between the periods corresponding to the peak population density frequencies predicted by the model and the ones reported in the literature. The model is used to study the relation between persistence, landscape area and predation. We use the notions of average time to extinction (ATE) and persistence frequency to quantify persistence. While the ATE decreases with decrease of area, it is a bell-shaped function of the predation level: increasing for "small" and decreasing for "large" predation levels.

AN - 67522638; 15696347 AB - Numerous environmental contaminants have been identified as endocrine disruptors (EDs)--substances that alter endocrine homeostasis by interfering with the biological action, production, or pharmacokinetics of endogenous hormones. Xenoestrogens are those EDs whose biological activity is similar to endogenous estrogen. This report presents data that identified Surflan, a proprietary herbicide emulsion, and its active ingredient oryzalin as xenoestrogens. In vitro, Surflan and oryzalin activated an estrogen-inducible reporter gene, and oryzalin competitively displaced 17beta-estradiol from the estrogen receptor. In vivo, Surflan and oryzalin induced expression of estrogen-regulated high-molecular-weight choriogenin genes in medaka (Oryzias latipes). These results are consistent with the characteristics of previously identified xenoestrogens and indicate that Surflan and oryzalin have the potential to adversely affect numerous estrogen-regulated biological processes.

AN - 67473085; 15706618 AB - Accelerator mass spectrometry (AMS) is a mass spectrometric method for quantifying rare isotopes. It has had a great impact in geochronology and archaeology and is now being applied in biomedicine. AMS measures radioisotopes such as 3H, 14C, 26Al, 36Cl and 41Ca, with zepto- or attomole sensitivity and high precision and throughput, allowing safe human pharmacokinetic studies involving microgram doses, agents having low bioavailability or toxicology studies where administered doses must be kept low (<1 microg kg(-1)). It is used to study long-term pharmacokinetics, to identify biomolecular interactions, to determine chronic and low-dose effects or molecular targets of neurotoxic substances, to quantify transport across the blood-brain barrier and to resolve molecular turnover rates in the human brain on the time-scale of decades. We review here how AMS is applied in neurotoxicology and neuroscience.

We sampled the Chemehuevi Mountain piedmont, a complex multisurfaced landform in the Mojave Desert, western United States. The nuclide data indicate that sediment is produced more rapidly (1.1X10 (super 5) kg.yr (super -1) .km (super -2) ) in steep mountain source basins than on the low-gradient pediment (4.0X10 (super 4) kg.yr (super -1) .km (super -2) ) or the intrapiedmont mountain range (2.5X10 (super 4) kg.yr (super -1) .km (super -2) ). However, the bulk of the sediment in transport is derived from erosion of the large abandoned alluvial surface (3.9X10 (super 4) kg.yr (super -1) .km (super -2) ). The combination of mass and nuclide budgeting suggests that sediment transport speeds decrease downslope from tens of meters per year in confined channels on the proximal pediment to decimeters per year in unconfined distributaries on distal wash surfaces. The sediment and nuclide budgeting approach we use is particularly valuable in arid regions where geomorphically significant events are infrequent and dating control is poor, thus confounding traditional sediment-budgeting techniques.

Lakes and drained thaw-lake basins account for approximately 75% of the modern surface expression of the Barrow Peninsula. The thaw-lake cycle usually obliterates lacustrine or peat sediments from previous cycles, which could otherwise be used for paleoecological reconstruction of long-term landscape and vegetation changes. Several possible erosional remnants of a former topographic surface that predates the formation of the thaw lakes have been tentatively identified. These remnants are characterized by a higher elevation, a thick organic layer with very high ground ice content in the upper permafrost and a plant community somewhat atypical of the region. Ten soil cores were collected from one site, and one core was intensively sampled for soil organic carbon content, pollen analysis and (super 14) C dating. The lowest level of the organic sediments represents the earliest phase of plant growth and dates to ca. 9000 cal BP. Palynological evidence indicates the presence of mesic shrub tundra (including sedge, birch, willow and heath vegetation), and microfossil indicators point to wetter eutrophic conditions during this period. Carbon accumulation was rapid due to high net primary productivity in a relatively nutrient-rich environment. These results are interpreted as the local response to ameliorating climate during the early Holocene. The middle Holocene portion of the record contains an unconformity, indicating that between 8200 and 4200 cal BP sediments were eroded from the site, presumably in response to wind activity during a drier period centered around 4500 cal BP. The modern vegetation community of the erosional remnant was established after 4200 cal BP and peat growth resumed. During the late Holocene, carbon accumulation rates (CARs) were greatly reduced in response to the combined effects of declining productivity associated with climatic cooling, and increased nutrient stress as paludification and permafrost aggradation sequestered mineral nutrients.

Fire is often used in California grasslands as a means of exotic species control, but the indirect effects these controls have on the reproductive ecology of native plants are rarely assessed. The interaction of fire with granivory of A. grandiflora seeds was examined in California grasslands over five years (1998-2002). In 1998 and 1999, both burned and unburned plots had bird-exclusion (netted) and no-exclusion (open) treatments. Predation rates were high (51-99%) and final predation rates did not differ among treatments. In 2000, granivory rates in the unburned, open plots were lower than in previous years (14%), and rodent trapping yielded only a single animal. Low granivory rates were observed in 2001 for unburned, open plots (47%). In 2001, burned/open plots experienced significantly more granivory (87%) than either burned/netted plots (37%) or unburned/open plots (47%). In 2002, every seed was taken from burned, open plots. Granivory was highly variable, ranging from 4 to 100% per plot over a 3-week period. Nearly all plots were discovered (>10% predation) by granivores in all trials in all years. When data from all treatments were combined, significant differences in granivory rates occurred among years, indicating stronger inter-year effects than within-year effects due to burning or bird exclusion. Fire affects granivory when overall predation rates are low, but when predation levels are high (as they were in 1998 and 1999), fire may not affect granivory occurring within the same year. Models extending seed survivorship through the dry summer indicate that most seeds are eaten, even when granivory rates are low.

Rates of decay were compared for assemblages composed of all species, autogenic species only, and allogenic species only. Rates of similarity decay were calculated by regressing a matrix of intercommunity distance against a matrix of intercommunity Sorenson similarity for each group of species. Significance was determined with the use of a Mantel test using 1,000 permutations. Significant rates of decay were found for all groups; however, allogenic similarity decayed according to an exponential function, whereas autogenic similarity decayed according to a linear function. Overall, the results suggest that autogenic-allogenic status is an important factor determining the rate at which similarity decays, but illustrate the need for more insight regarding the factors that affect parasite dispersal ability.

The violence of the subsequent reaction varies from benign slow combustion to catastrophic detonation of the entire charge. The degree of violence depends on many variables, including the rate of energy delivery, the physical and chemical properties of the explosive, and the strength of the confinement surrounding the explosive charge. The current state of experimental and computer-modeling research on the violence of impact, thermal, and shock-induced reactions is briefly reviewed in this paper.

AN - 67272649; 15533833 AB - The Fanconi anemia (FA) proteins overlap with those of homologous recombination through FANCD1/BRCA2, but the biochemical functions of other FA proteins are largely unknown. By constructing and characterizing a null fancg mutant (KO40) of hamster CHO cells, we show that FancG protects cells against a broad spectrum of genotoxic agents. KO40 is consistently hypersensitive to both alkylating agents that produce monoadducts and those that produce interstrand crosslinks. KO40 cells were no more sensitive to mitomycin C (3x) and diepoxybutane (2x) than to 6-thioguanine (5x), ethylnitrosourea (3x), or methyl methanesulfonate (MMS) (3x). These results contrast with the pattern of selective sensitivity to DNA crosslinking agents seen historically with cell lines from FA patients. The hypersensitivity of KO40 to MMS was not associated with a higher level of initial DNA single-strand breaks; nor was there a defect in removing MNU-induced methyl groups from DNA. Both control and MMS-treated synchronized G1-phase KO40 cells progressed through S phase at a normal rate but showed a lengthening of G2 phase compared with wild type. MMS-treated and untreated early S-phase KO40 cells had increased levels of Rad51 foci compared with wild type. Asynchronous KO40 treated with ionizing radiation (IR) exhibited a normal Rad51 focus response, consistent with KO40 having only slight sensitivity to killing by IR. The plating efficiency and doubling time of KO40 cells were nearly normal, and they showed no increase in spontaneous chromosomal aberrations or sister chromatid exchanges. Collectively, our results do not support a role for FancG during DNA replication that deals specifically with processing DNA crosslinks. Nor do they suggest that the main function of the FA protein "pathway" is to promote efficient homologous recombination. We propose that the primary function of FA proteins is to maintain chromosomal continuity by stabilizing replication forks that encounter nicks, gaps, or replication-blocking lesions.

Mutations in the N-terminal KKLK motif of Rad51B (amino acids 4-7), result in the cytoplasmic localization of Rad51B suggesting that the KKLK sequence is the nuclear localization signal (NLS) for the Rad51B protein. Examination of wild-type EGFP-Rad51B fusion protein in hamster irs3 mutant cells, deficient in Rad51C, showed that Rad51B localizes to the nucleus independently of Rad51C, the only known direct binding partner for Rad51B. Utilization of a BRCA2 mutant cell line, CAPAN-1, showed that Rad51B also localizes to the nucleus independent of BRCA2. Although both Rad51B and BRCA2 are clearly involved in the homologous recombinational repair pathway, Rad51B and BRCA2 do not appear to associate. This study finds that a KKLK motif in the N-terminus of Rad51B serves as an NLS that allows Rad51B to localize to the nucleus independent of Rad51C or BRCA2.

AN - 67377448; 15657483 AB - Nuclear magnetic resonance (NMR) spectroscopy is a powerful technique for studying bimolecular interactions at the atomic scale. Our NMR laboratory is involved in the identification of small molecules, or ligands, that bind to target protein receptors such as tetanus neurotoxin (TeNT) and botulinum neurotoxin, anthrax proteins, and HLA-DR10 receptors on non-Hodgkin lymphoma cancer cells. Once low-affinity binders are identified, they can be linked together to produce multidentate synthetic high-affinity ligands (SHALs) that have very high specificity for their target protein receptors. An important nanotechnology application for SHALs is their use in the development of robust chemical sensors or biochips for the detection of pathogen proteins in environmental samples or body fluids. Here we describe a recently developed NMR competition assay based on transferred nuclear Overhauser effect spectroscopy that enables the identification of sets of ligands that bind to the same site, or a different site, on the surface of TeNT fragment C (TetC) than a known "marker" ligand, doxorubicin. Using this assay, one can identify the optimal pairs of ligands to be linked together for creating detection reagents, as well as estimate the relative binding constants for ligands competing for the same site.

AN - 67331153; 15623307 AB - The autonomous pathogen detection system (APDS) is an automated, podium-sized instrument that continuously monitors the air for biological threat agents (bacteria, viruses, and toxins). The system has been developed to warn of a biological attack in critical or high-traffic facilities and at special events. The APDS performs continuous aerosol collection, sample preparation, and detection using multiplexed immunoassay followed by confirmatory PCR using real-time TaqMan assays. We have integrated completely reusable flow-through devices that perform DNA extraction and PCR amplification. The fully integrated system was challenged with aerosolized Bacillus anthracis, Yersinia pestis, Bacillus globigii, and botulinum toxoid. By coupling highly selective antibody- and DNA-based assays, the probability of an APDS reporting a false positive is extremely low.

AN - 67275259; 15502208 AB - A protocol is described for the isolation of DNA and subsequent preparation of samples for the measurement of adduct levels by accelerator mass spectrometry (AMS). AMS is a highly sensitive technique used for the quantification of adducts following exposure to carbon-14- or tritium-labeled chemicals, with detection limits in the range of one adduct per 10(11)-10(12) nucleotides. However, special precautions must be taken to avoid cross-contamination of isotope between samples and to produce a sample that is compatible with AMS. The DNA isolation method described is based on digestion of tissue with proteinase K, followed by extraction of DNA using Qiagen DNA isolation columns. DNA is then precipitated with isopropanol, washed repeatedly with 70% ethanol to remove salt, and then dissolved in water. This method has been used to generate reliably good yields of uncontaminated, pure DNA from animal and human tissues for analysis of adduct levels. For quantification of adduct levels from 14C-labeled compounds, DNA samples are then converted to graphite, and the 14C content is measured by AMS. JF - Methods in molecular biology (Clifton, N.J.)

The landslide basal surface preserves large "striations" ( approximately 9-km long) which appear to record the catastrophic failure and show dramatic evidence for basal erosion over an area >130 km (super 2) . These "striations" terminate abruptly up-slope at a major growth fault. The landslide head terminates at this fault, and an earthquake or fluid flow associated with that fault may have triggered the failure event. Within the landslide deposit, giant tabular blocks approximately 1- to 5-km across and approximately 100- to 150-m thick and chaotic debris flow deposit indicate rapid emplacement. The landslide surface geometry reveals block disaggregation and a fully developed debris flow facies less than 5 km from source. The landslide deposit extends to the SW beyond the study area, so volume and area are underestimated. Volume estimates of the landslide deposit exceed the failure scar volume by a factor of 2 or more, indicating significant seafloor remobilisation during emplacement. Results give new insights into the triggering mechanisms and basal erosion processes of submarine landslide failure.

Forty years after its discovery, the origin of the feature and the nature of the carrier(s) remain controversial. Using a transmission electron microscope, we detected a 5.7-electron volt (2175 angstrom) feature in interstellar grains embedded within interplanetary dust particles (IDPs). The carriers are organic carbon and amorphous silicates that are abundant in IDPs and in the interstellar medium. These multiple carriers may explain the enigmatic invariant central wavelength and variable bandwidth of the astronomical 2175 angstrom feature.

This rate is 10 times larger than that inferred from recent InSAR analyses ( approximately 1+ or -3 millimeters per year) that span approximately 8 years and sample all branches of the fault. The difference in slip-rate determinations suggests that large rate fluctuations may exist over centennial or millennial time scales. Such fluctuations would be consistent with mechanical coupling between the seismogenic, brittle-creep, and ductile shear sections of faults that reach deep into the crust.

The Clyde Foreland is composed of two distinct landscape zones: (1) glacially scoured terrain proximal to the major sources of Laurentide ice that flowed onto the foreland, and (2) ice distal unscoured sectors of the foreland. Both zones are draped with erratics and dissected by meltwater channels, indicating past ice cover. We interpret the two landscape classes in terms of ice sheet erosive ability linked with basal thermal regime: glacially scoured terrain was occupied by erosive warm-based ice, and unscoured terrain was last occupied by non-erosive cold-based ice. Cosmogenic exposure ages from >100 erratics from the two landscape types have different age distributions. Cosmogenic exposure ages from the glacially scoured areas suggest ice cover during the LGM, followed by deglaciation between approximately 15 and approximately 12 ka. In the unscoured lowlands, the cosmogenic exposure ages have multiple modes ranging between approximately 12 and approximately 50 ka, suggesting multiple periods of cold-based ice cover during the last glacial cycle. In landscapes covered by cold-based ice, large numbers of cosmogenic exposure ages are required for elucidating glacial histories.

During the late 1930s to early 1940s, surface waters within and outside of the Cariaco Basin were similar. Within the Cariaco Basin at Islas Tortugas, coral Delta (super 14) C averages -519+ or -3.3 ppm. Corals collected outside of the basin at Boca de Medio and Los Testigos have Delta (super 14) C values of -53.4+ or -3.3 ppm and -54.3+ or -2.6, respectively. Additional (super 14) C analyses on the Isla Tortugas coral document an approximately 11 ppm decrease between approximately 1905 (-40.9+ or -4.5 ppm) and approximately 1940. The implied Suess effect trend (-3 ppm/decade) is nearly as large as that observed in the atmosphere over the same time period. If we assume that there is little to no fossil fuel (super 14) CO (sub 2) signature in Cariaco surface waters in approximately 1905, the waters have an equivalent reservoir age of approximately 312 yr.

A series of 127 (super 14) C ages reveals a chronological sequence that spans from 8940-110 cal BP (1 sigma ). This sequence serves as a foundation for the interpretation of behavioral change along the northern California coast over the last 9000 yr, including the adaptive strategies used by human foragers to colonize and inhabit coastal areas of this region. These (super 14) C ages will also permit us to explore major dimensions of temporal change in Holocene ocean conditions (via marine reservoir corrections) and their potential effect on the resources available to ancient hunter-gatherers.

AN - 51598398; 2006-037405 AB - Porous rock near the earth's surface often contains more than one fluid phase, and an important case is partial saturation with air and water. We implemented a pore-scale, percolation model coupled with a continuum model for water vapor diffusion in order to create a simulated tomographic image of water distribution within a rock core during drying. As drying proceeds, the initial, continuous water cluster breaks up into smaller and smaller clusters with an increasing surface-area-to-volume ratio. Drying times are a function of the number and location of boundary surfaces, but the surface-area-to-volume ratio is approximately the same for a given saturation. By applying a Voigt volume average of the elastic properties of water-filled and air-filled cells, and by introducing the ad hoc rule that water-filled pores on the air-water interface of a cluster behave in a drained manner, we find elastic moduli as a function of saturation that mimic laboratory experimental data.

Substantial differences were observed in the soil-plant transfer factor (TF) among these radionuclides and plant species. Lupine (Lupinus albus) exhibited the highest uptake of (super 238) U (TF value of 3.7X10 (super -2) ), while Chinese mustard (Brassica chinensis) had the least (0.5X10 (super -2) ). However, in the case of (super 226) Ra and (super 232) Th, the highest TFs were observed for white clover (Trifolium pratense) (3.4X10 (super -2) ) and ryegrass (Lolium perenne) (2.1X10 (super -3) ), respectively. (super 232) Th in the tailings/soil mixture was less available for plant uptake than (super 226) Ra or (super 238) U, and this was especially evident for Chinese mustard and corn (Zea mays). The root/shoot (R/S) ratios obtained for different plants and radionuclides shown that Indian mustard had the smallest R/S ratios for both (super 226) Ra (5.3+ or -1.2) and (super 232) Th (5.3+ or -1.7), while the smallest R/S ratio for (super 238) U was observed in clover (2.8+ or -0.9).

The experiments were in the context of Comprehensive Test Ban Treaty (CTBT) monitoring in the Middle East and aimed to improve the Earth crust velocity models for calculating travel times to regional and International Monitoring System (IMS) stations, to extend the Ground Truth (GT0) database, and to observe and quantify dynamic features of seismic sources and elaborate scaling laws. The experiments contributed to the study of explosion source phenomenology in various geological settings and to understanding the main features of seismic energy generation from point-like sources, thus improving the classification of seismic events, which is the crucial issue of nuclear monitoring. The network and array observations obtained were used for joint location analysis of the explosions, based on up-to-date algorithms and software and Ground Truth parameters, and for estimation of location accuracy and improvement of regional velocity models. In conjunction with the developed velocity models, we compared the Ground Truth location and origin to those calculated using a standard location routine, the Levenberg-Marquardt procedure, and several beamforming techniques. We found that the Network Location Beamforming works best.

Detailed paragenetic studies indicate that wairakite typically forms after the deposition of epidote+prehnite and later anhydrite+calcite. Epidote and prehnite are interpreted as products of early, high temperature alteration associated with upwelling reservoir fluids whereas calcite and anhydrite are related to descending acidic condensates. Calculated stability relationships among the calc silicate minerals indicates that cooling and/or decreasing pH will lead to the deposition of wairakite instead of epidote, whereas decreasing pH favors wairakite over prehnite. We infer, from the petrographic relationships, that these changes occur when descending condensate mixes with the in-situ reservoir fluids during the waning stages of geothermal activity. Fluid inclusion measurements indicate wairakite is commonly deposited between temperatures of nearly equal 235 and 300 degrees C.

In the gravitational collapse theory, after a proto-star has consumed all the initial gas it may continue accreting from the parent clump but will not accrete sufficiently to change its mass. In the alternative theory of competitive accretion, after the inital core is consumed the amount accreted will be larger than the proto-stellar mass. Here, the rate of competitive accretion is derived partly by simulation methods, as a function of the star-forming environment. Observed star-forming regions are summarized and from calculations of acccretion of unbound gas, none has a value near unity which is inconsistent with competitive accretion but is consistent with gravitational collapse. The theory of competitive accretion is based on assumed properties different from those determined through observation.

In many previous studies, estimates of S sub(y) and K sub(z) were observed to be highly variable and physically unrealistic. This has been attributed to the conceptualization of flow above the declining water table and aquifer heterogeneity in the applied models. We present the analysis of time-drawdown data from a pumping test instrumented with depth-differentiated observation piezometers arranged in clusters. Applying homogeneous anisotropic aquifer models in combination with nonlinear least squares parameter identification techniques, the data were analyzed in different groups: analysis of data from individual piezometer clusters and simultaneous analysis of the entire data set from all piezometer clusters (global analysis). From the cluster analyses, estimates of S sub(y) and K sub(z) exhibit large variances and depart from a priori estimates inferred from the hydrostratigraphy. Parameter estimates from the global analysis do not fall within the parameter bounds (minimum and maximum values) defined by the cluster analyses. While heterogeneity appears to be the important reason for large parameter variances, we discuss the influence of rarely considered aquifer return flow on drawdown and the inconsistent results from the cluster and global analyses. We corroborate our findings with data on hydraulic gradients, slug test data, and results from the application of a more realistic numerical flow model.

This method provides the sensitivity to trace Be in biological samples at very low doses with the purpose of identifying the molecular targets involved in chronic beryllium disease. Proof of the method was tested by administering 0.001, 0.05, 0.5, and 5.0 mu g of super(9)Be and super(10)Be by intraperitoneal injection to male mice and removing the spleen, liver, femurs, blood, lungs, and kidneys after 24 h of exposure. These samples were prepared for AMS analysis by tissue digestion in nitric acid, followed by further organic oxidation with hydrogen peroxide and ammonium persulfate and, last, precipitation of Be with ammonium hydroxide and conversion to beryllium oxide at 800 degree C. The super(10)Be/ super(9)Be ratio of the extracted beryllium oxide was measured by AMS, and Be in the original sample was calculated. Results indicate that Be levels were dose-dependent in all tissues and the highest levels were measured in the spleen and liver. The measured super(10)Be/ super(9)Be ratios spanned 4 orders of magnitude, from 10 super(-10) to 10 super(-14), with a detection limit of 3.0 x 10 super(-14), which is equivalent to 0.8 amol of super(10)Be.

AN - 67070230; 15545765 AB - Based on annual tritium release rates from the five sources of tritium at Lawrence Livermore National Laboratory and the Tritium Research Laboratory at Sandia National Laboratory, the regulatory dispersion and dose model, CAP88-PC, was used to predict tritium concentrations in air at perimeter and offsite air surveillance monitoring locations for 1986 through 2001. These predictions were compared with mean annual measured concentrations, based on biweekly sampling. Deterministic predictions were compared with deterministic observations using predicted-to-observed ratios. In addition, the uncertainty on observations and predictions was assessed: when the uncertainty bounds of the observations overlapped with the uncertainty bounds of the predictions, the predictions were assumed to agree with the observations with high probability. Deterministically, 54% of all predictions were higher than the observations, and 96% fell within a factor of three. Accounting for uncertainty, 75% of all predictions agreed with the observations; 87% of the predictions either matched or exceeded the observations. Predictions equaled or exceeded observations at those sampling locations towards which the wind blows most frequently, except those in the hills. Under-predictions were seen at locations towards which the wind blows infrequently when released tritium was from elevated sources. When a high fraction of tritium was from area (diffuse) sources, predictions matched observations.

AN - 67029290; 15519370 AB - Laboratory experiments were conducted to determine environmental variables that affect the affinities and persistence of the nerve agent O-ethyl S-(2-diisopropylaminoethyl) methylphosphonothiolate (VX) at dilute concentrations in environmental matrices. Quantitative analyses of VX and its degradation products were performed using LC-MS. Batch hydrolysis experiments demonstrated an increasing hydrolysis rate as pH increased, as shown in previous studies, but also indicated that dissolved aqueous constituents can cause significant differences in the absolute hydrolysis rate. Adsorption isotherms from batch aqueous experiments revealed that VX has a high affinity for hydrophobic organics, a moderate affinity for montmorillonite clay, and a very low affinity for an iron-oxyhydroxide soil mineral, goethite. The adsorption on goethite was increased with the presence of dissolved organic matter in solution. VX degraded rapidly when dried onto goethite, when specific adsorption was forced. No enhanced degradation occurred with goethite in small amounts of water. These results suggest that aqueous conditions have important controls on VX adsorption and degradation in the environment and a more mechanistic understanding of these controls is needed in order to enable accurate predictions of its long-term fate and persistence.

In order to apply these monitors, however, many issues influencing system response and data analysis must be addressed. This study examines the use of a continuous flow-through toxicity monitor (Bioscan registered ) to (1) determine the sensitivity, accuracy, and precision of the toxicity monitor to different concentrations of a stressing agent (in this case pH), (2) establish operational and maintenance procedures, and (3) examine the consistency in the measured response to a single perturbation. The system precision was sensitive to all the pH pulse perturbations, with stable background variability (1% to 6%); however, replicated pulse applications demonstrated that the system has lower accuracy (31% to 38%). The response consistency was limited, with notable differences in maximum dissolved oxygen and recovery time. The initial response time (inclining slope) was relatively consistent. Although this examination should be repeated with other contaminants used to stress the toxicity monitor, it appears that continuous flow-through toxicity monitors like the Bioscan registered are well suited for qualitative early alert warning systems for water contamination.

The splat texture at each level is generated by rendering its children in a hierarchical model, from a distribution of viewing directions, and averaging the result. For rendering, the ellipsoids to be used are chosen adaptively, depending on the distance to the viewpoint. This technique is applied to visualize DNA coiling around nucleosomes in chromosomes.

Our method is based in the chemoselective reaction between a protein C-terminal alpha -thioester and a modified surface containing N-terminal Cys residues. alpha -Thioester proteins can be obtained using standard recombinant techniques by using expression vectors containing engineered inteins. This new method was used to immobilize two fluorescent proteins and a functional SH3 domain using a protein microarrayer.

Thermodynamic modeling has traditionally been used to study environmental metal contaminant migration (especially uranium and other radionuclides), allowing examination of chemical processes difficult to study experimentally. However, such techniques are rarely used in the study of metal toxicology. Chemical thermodynamics has a unique and valuable role in developing models to explain metal metabolism and toxicology. Previous computational models of beryllium in simulated biological fluids have been shown to be useful in predicting metal behavior in the human body. However, previous studies utilizing chemical thermodynamics in understanding uranium chemistry in body fluids are limited. Here, a chemical thermodynamic speciation code has been used to model and understand the chemistry of uranium in simulated human biological fluids such as intracellular, interstitial, and plasma fluids, saliva, sweat, urine, bile, gastric juice, pancreatic fluid, and a number of airway surface fluids from patients with acute lung conditions. The results show predicted uranium solubility, and speciation varies markedly between each biological fluid due to differences in fluid composition, ionic strength, and pH. The formation of uranium hydroxide, phosphate (sodium/potassium autunite), and calcium uranate was observed in most of the fluids. The results of this work, supported by experimental validation, can aid in understanding the metabolism and toxic effects of uranium with potential applications to biological monitoring as well as chelation treatment of uranium body burden.

To the extent this is true, bomb-pulse (super 36) Cl may be used as a groundwater age indicator in shallow aquifers or alpine catchments, much the same way tritium has been used. Chlorine-36/chloride ratios in shallow groundwater (<100 m) in the Wawona catchment of Yosemite National Park indicate a bomb-pulse source of (super 36) Cl. Precipitation collected in the area has (super 36) Cl/Cl ratios near 100 X 10 (super -15) , where groundwater measured in the top one hundred meters from ground surface have (super 36) Cl/Cl ratios ranging between 1000-10,000 X 10 (super -15) . Chlorine-36/Chloride ratios measured in the Merced River in Yosemite National Park also had values similar to those measured in shallow groundwater. This would suggest that the mean residence time of water flowing in the Merced River was on the order of approximately 40 yrs. Helium-3, Tritium, CFCs, and SF6 samples collected in springs in the Sierra Nevada indicate that groundwater is on the order of a few years to four decades old. Water balance considerations suggest that only a fraction of the water discharging in the Merced River may be four or five decades old, but much of the water may be significantly younger. It is possible that chloride may not behave conservatively in the Merced River basin, and using (super 36) Cl as an age dating tool may overestimate the mean groundwater travel time. Recent findings suggest that chloride is taken up in heavily forested ecosystems, which would then recycle the chloride to the saturated or unsaturated zones. Other findings also show that (super 36) Cl has an affinity to low molecular weight humic substances in soils. Comparison of (super 36) Cl "ages" with water ages determined by radon, tritium, and other means provides evidence for the degree of attenuation of chloride in the Merced River basin, and raises questions concerning its utility as a conservative tracer in hydrologic systems.

The first technique exploits variations in inherited TCN in 45 bedrock samples at different altitudes, and demonstrates a clear, inverse relationship between erosion rate and altitude in the Torngat Mountains, Labrador. Samples from tors on summits indicate maximum erosion rates as low as 1.6 m/Myr. Samples from streamlined bedrock protrusions a few meters above the valley floors have no inheritance (bedrock and erratic concentrations are equivalent) and consistently indicate erosion > 3 m during the last glaciation. The second approach uses the inherited TCN concentration measured in glacio-lacustrine deltaic sediment and till from north Baffin Island, Nunavut to calculate relative variations in the plateau-wide paleo-erosion rate and to qualitatively assess the duration of glacial transport and ice velocity. Deltaic sediment samples contain an inheritance equivalent to ca. 25 kyr. The erosion rates of the upland source areas at the time of delta deposition range from 8 to 15 m/Myr for maximum and minimum modeled ice cover, respectively. Based on preliminary measurements, we hypothesize that bouldery tills with monolithologic, angular clasts ("short distance tills") that are sometimes associated with cold-based ice have relatively high TCN concentrations, whereas tills with a silty matrix and polylithologic, subrounded and striated clasts ("long distance tills"), contain little to no inherited TCN. We hope to use the distribution of till TCN inventories in concert with the University of Maine Ice Sheet Model (UMISM) with a basal temperature calculation to predict the distribution of stable, frozen-bed regions. Predicted distributions in northern Baffin grossly match zones of felsenmeer that cover the upland surfaces, as has been documented in the Torngat Mountains of Labrador.

The question of timing underpins all paleoclimate reconstructions for the tropics. A definitive chronology for the LGM has been elusive, in large part due to the limitations of radiocarbon dating and the scarcity of datable material in high-altitude glacial environments. We present an absolute chronology for the LGM in the tropical Andes based on cosmogenic dating ( (super 10) Be) of glacial erratics on moraines. The LGM in the Junin region of the central Peruvian Andes (11S 76W) and in the Cordillera Real of Bolivia (16 degrees S 68 degrees W) occurred approximately 34,000 to 22,000 (super 10) Be years before present (BP) and was less extensive than older glaciations. Recession from LGM moraines approximately 21,000 (super 10) Be years BP was followed closely by stillstand until approximately 15,000 (super 10) Be years BP, when final deglaciation began. Our terrestrial glacial chronology is consistent with lacustrine paleoclimate records from nearby lakes: Lake Junin (11 degrees S 76 degrees W) on the Junin Plain of Peru and Lake Titicaca (16 degrees S 69 degrees W) on the Peruvian-Bolivian Altiplano. LGM snowline depression was 300-600 m, except where local factors such as shading and debris cover produced glacier expansion to lower elevations. Regional evidence for a wet LGM in the tropical Andes suggests that limited temperature depression, rather than lack of moisture, constrained the size of LGM glaciers. Asynchrony between the LGM in the Northern Hemisphere ( approximately 21,000 years BP) and the tropical Andes ( approximately 34,000-22,000 years BP) implies decoupling of climate forcing mechanisms and the need to reexamine climate models based on assumptions of a globally synchronous LGM.

Cosmogenic exposure dating, supplemented with radiocarbon dating, has constrained the timing of advance and retreat of glaciers during marine isotope stage (MIS) 2. In the northeast corner of North America, the LIS outlet glacier that filled Clyde Fiord expanded sometime after approximately 34 ka to its terminal position on the continental shelf of Baffin Bay, it retreated from its terminal position approximately 13 ka, fluctuated in the outer fiord until 10 ka, retreated rapidly to the fiord head by 9 ka, and finally receded from the fiord head approximately 8 ka. In the northwest corner of North America, we have constrained the timing of deglaciation from terminal MIS 2 moraines in six regions across the State of Alaska; the advance phase is constrained at three of these sites. Alpine glaciers generally began to advance between 30 and 25 ka, reaching terminal positions between approximately 27 and approximately 21 ka. Glaciers retreated from their local MIS 2 maxima: approximately 22 ka in the Ahklun Mountains (SW Alaska); approximately 16-18 ka in the Chuilnuk Mountains (SW Alaska); approximately 20 ka in the western Alaska Range (central Alaska); approximately 24-27 ka in the Kokrines Hills (west-interior Alaska); approximately 21-23 ka in the Yukon Tanana Upland (east-interior Alaska); and approximately 24-26 ka in the northeastern Brooks Range (NE Alaska). Overall, glacier retreat in Alaska was concurrent with the peak of the last global glacial maximum, probably in response to limited moisture availability. On the other hand, the retreat of the northeastern LIS occurred late during global deglaciation, possibly because this sector of the LIS was sustained for some time by local increases in precipitation during climate amelioration. The records from these areas stress the importance of local factors in influencing the details of glacier histories.

In this study, we measure helium (He) concentrations and isotopic ratios in springs in the Oregon Cascades volcanic arc and in eastern Oregon, including the northwestern extent of the Basin and Range. We show that in order to estimate mantle (magmatic) He contributions to groundwaters, it is critical to simultaneously consider 1) He isotopic ratios, 2) He concentrations, and 3) mixing of He components from the crust, mantle, and air-saturated water. Our results suggest that mantle fractions (F) of excess (crustal + mantle) He contributions to cold springs that are fed by deep groundwater flow beneath the eastern flanks of the Oregon Cascades are comparable to F of up to 0.7 in thermal springs on the western flanks. Similarly, we find excess He isotopic ratios of up to 5.3 Ra on either side (east and west) of the Oregon Cascades, where Ra is the He isotopic ratio of the atmosphere. Furthermore, while these mantle He contributions are largest in deep groundwaters near the Cascades crest, greater mantle excess He fractions (F) than would be inferred from He isotopic ratios alone are present in all (deep) groundwaters including those at larger distances (>70 km) from the volcanic arc. We also suggest that excess He and heat discharge without dilution by air-saturated water may be restricted to spring discharge along faults.

At the time of the experiment, the artificial recharge rate was approximately 4 m/day and the water table was approximately 12 m below the ground surface. Breakthrough curves of SF6 and He-3 at two nearby production wells were very similar. At one well screened between 50 and 90 m below ground, both tracers were detected after 5 days and reached a maximum at approximately 24 days. Despite potential dilution caused by mixing within the production well, the maximum concentration observed at this well was approximately 25% of the mean pond concentration. Noble gas concentrations in the groundwater were much higher than in the pond due to the dissolution of trapped air. However, significant retardation (absolute and relative) of the gas tracers was not detected suggesting that the amount of trapped air was small. The experiment demonstrates that at artificial recharge sites with high infiltration rates and moderately deep water tables, transport times between recharge locations and wells determined with gas tracer experiments are reliable.

Lawrence Livermore National Laboratory, in collaboration with the U.S. Geological Survey, has analyzed dissolved gases in more than 1200 water supply wells across California as part of the Groundwater Ambient Monitoring and Assessment (GAMA) program of the California State Water Resources Control Board. Samples were analyzed for noble gases (He, Ne, Ar, Kr, Xe) as well as tritium and delta (super 18) O. A noteworthy aspect of the data set is the large range in excess air concentrations. The majority of high excess air samples are from wells in coastal basins, while wells in Central Valley basins show much lower values. For example, significant fractions of wells within Orange County and Santa Clara County have excess air concentrations of >15 cm (super 3) /kg (some as high as 40 cm (super 3) /kg) while both Sacramento and San Joaquin County have mean excess air <5 cm (super 3) /kg. Many high excess air values in the heavily urbanized coastal basins are attributed to artificial recharge; however high values are also found in areas of Santa Clara County without major artificial recharge facilities. Groundwater recharged prior to the 1950s (i.e., tritium <1 pCi/L) generally contains lower amounts of excess air relative to more recently recharged water. The presence of 15 cm (super 3) /kg of excess air introduces approximately 50% more dissolved oxygen to groundwater than equilibrium solubility alone. Increased dissolved oxygen can greatly impact geochemical reactions such as denitrification and oxidation of organic carbon during groundwater recharge and transport.

The high peaks of this range are currently glaciated, and past glaciations include the Holocene, late Glacial, LGM, and a probable older stage. We present results from a study to map glacial features, determine the glacial chronology, and reconstruct paleo-ELAs throughout the range. Cosmogenic ages (10Be) of quartz-bearing rocks on moraine ridges are used to determine the extent of the LGM and other major stages of glaciation in this little known area. Field work focused on the Jahuacocha Valley, draining the western side of the cordillera, and the Carhuacocha and Mitucocha Valleys, both major drainages of the eastern side of the range. Glacial features were mapped using hand-held global positioning system units, as well as aerial photographs, and Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) satellite data. We use ASTER-derived digital elevation models, 3 arc second ( approximately 90 m) shuttle radar topography mission (SRTM) digital elevation data for South America, and digitized 1:100,000 topographic maps to reconstruct ELAs. Initial cosmogenic dates from Jahuacocha moraines suggest that the glaciers of the late Glacial were nearly as great as at any time during the preserved geologic record. The elevation of maximum glacial extent is similar in these three major drainages, suggesting a smaller-than-expected variation in ELA depression, if glacier maxima were contemporaneous. Valley hypsometry is variable throughout the range, and probably was an important control on glacier development. In some cases, low altitude tributaries contribute a substantial ice volume to the main valleys, which may be an important key to constraining paleo snowline altitude variations. From the mapped moraine positions and valley shapes we reconstruct probable glacier area and ELA for each stage. Field and satellite based glacier reconstructions in the Jahuacocha, Carhuacocha, and Mitucocha Valleys are a major step in developing an improved understanding of the spatial gradients in paleo glacier extent, ELA, and ELA depression at a critical tropical location.

Advanced techniques such as groundwater age-dating using the tritium-helium method, and analysis of common volatile organic compounds (VOCs) at ultra-low levels are applied with the goal of assessing the contamination vulnerability of deep aquifers, which are frequently used for public drinking water supply. This effort is an important prelude to the statewide groundwater quality monitoring and assessment (GAMA) program. Over 1200 public drinking water wells have been tested to date, resulting in a very large, tightly spaced, collection of groundwater ages in some of the heavily exploited groundwater basins of California. When employed on a basin-scale, groundwater ages are an effective tool for identifying recharge areas, defining flowpaths, and determining the rate of transport of water and associated contaminants. De-convolution of mixed ages, using ancillary dissolved noble gas data, gives insight into the water age distribution drawn at a well, and into the effective dilution of contaminants at long-screened production wells. In combination with groundwater ages, low-level VOCs are used to assess the significance of vertical transport. For example, low-level analyses show that tetrachloroethylene (PCE), occurs much more frequently in basins from California's Central Valley (49% of wells) than in coastal areas (9% of wells); the presence of continuous confining units in coastal basins likely prevents downward migration of PCE and other contaminants, while semi-confined aquifers in the Central Valley allow some vertical migration of solvents to deep groundwater. The advantages and limitations of applying these technologies, and of the public water supply well sample set, will be illustrated in a comparison of results from the coastal Santa Clara Valley basin and the Sacramento Basin of the Central Valley.

In response to the many potential sources of groundwater contamination, Federal, State, and Local agencies each approach groundwater quality issues from the perspective of their own mandate. As a result, each agency collects different types of groundwater data and information. Despite the volume of groundwater-related monitoring data, data sharing and coordination between agencies has been limited. Based on statewide public supply well water quality data monitored by the Department of Health Services, more than 8000 public water supply wells have been taken out of service in the last 20 years--many for water quality reasons. The MTBE scare of the late 1990s is being supplanted by concerns over perchlorate and other emergent chemicals. To adequately protect and manage California's groundwater resources, it is imperative that California establish a baseline of groundwater quality and groundwater use for each groundwater basin in the state. Such a baseline can then be used as a reference for local management decisions, water quality trend monitoring, basin to basin comparisons, as well as establishing priorities for cleanup of surface contaminants that may affect groundwater. In response to the Groundwater Quality Monitoring Act of 2001, the SWRCB convened an Interagency Task Force and a Public Advisory Committee, together representing more than 19 different Federal, State, local, and private entities. This interagency effort resulted in a publicly accepted plan to monitor and assess the quality of all priority groundwater basins that account for over 90% of all groundwater used in the state. The plan builds on the existing GAMA Program and prioritizes groundwater basins for assessment based on groundwater use. The primary objectives of the GAMA Program are to improve comprehensive statewide groundwater monitoring, create a centralized groundwater quality database, and increase the availability of groundwater quality information to the public. Key aspects of the program include interagency collaboration, data sharing, and communication with local water agencies.

Sources of nitrate include fertilizer, confined animal feeding operations, and septic systems. Given rapid urbanization, increase in fertilizer use, and industrialization of farming since the 1940's, future impact of nitrate contamination is not well understood. To better understand long-term basin-scale nitrate transport, we are developing high-resolution nitrate transport models that include consideration of alluvial and microbiological heterogeneity. Alluvial heterogeneity is characterized by combining transition-probability/Markov and Gaussian random field geostatistical methods. The geostatistical approach considers numerous (but low quality) driller's logs as "soft data" to help constrain the hydrogeologic model. The geostatistical model also serves as a template for identifying potential zones of denitrification, where microbial activity may convert nitrate to nitrogen gas. Unless denitrification occurs, nitrate transport behaves like a conservative tracer. Under certain conditions of low dissolved oxygen and no organic carbon, "autotrophic" denitrification can occur with presence of an electron donor such as pyrite. Conditions for denitrification will vary tremendously within a groundwater basin. At our dairy field site, we are identifying zones of active denitrification and obtaining samples for laboratory analysis to quantify changes in populations of denitrifying bacteria for parameterization of Monod kinetic denitrification rate models. Isotopically-determined groundwater ages help calibrate the flow and transport models and scale-up laboratory and field results to the basin scale. Preliminary modeling results indicate that without denitrification or decreased nitrate loading, nitrate will eventually contaminate deeper aquifers used for municipal water supplies.

Recently, cosmogenic nuclides such as 10Be and 26Al have become important new tools for measuring long-term denudation rates. Cosmogenic nuclides are produced in-situ within mineral grains by cosmic ray bombardment. Because this cosmic ray flux is attenuated by the mass overlying the sample, the accumulated cosmogenic nuclide concentration in a sample records how rapidly the overlying mass (and thus the cosmic ray shielding) has been removed, either by physical erosion or chemical weathering. Thus cosmogenic nuclides can be used to measure the total denudation flux (the sum of the rates of physical erosion and chemical weathering). We have recently shown how this total denudation flux can be partitioned into its physical and chemical components, using the enrichment of insoluble tracers (such as Zr) in regolith relative to its parent rock. Thus by combining cosmogenic nuclide measurements with the bulk elemental composition of rock and soil, we can measure rates of physical erosion and chemical weathering over 1000- to 10,000-year time scales. We have measured long-term chemical weathering rates for 42 sites in granitic terrain, encompassing widely varying climates and denudation rates. Chemical weathering rates are highest at the sites with rapid denudation rates, consistent with strong coupling between rates of chemical weathering and mineral supply from breakdown of rock. The temperature sensitivity of chemical weathering rates is 2 to 4 times smaller than what one would expect from laboratory measurements of activation energies for feldspar weathering and previous intercomparisons of catchment mass-balance data from the field. Our results suggest that climate change feedbacks between temperature and silicate weathering rates may be weaker than previously thought, at least in actively eroding, unglaciated terrain similar to our study sites. To the extent that chemical weathering rates are supply-limited in mountainous landscapes, factors that regulate rates of mineral supply from erosion, such as tectonic uplift, may lead to significant fluctuations in global climate over the long term.

For a porous aggregate medium such as granular tuff, the total water content is comprised of surface water and interior water. The surface water component (water film around grains and pendular water between the grain contacts) could serve as a predominant diffusion pathway. To investigate the extent to which surface water films and contact points affect solute diffusion in unsaturated gravel, we examined the configuration of water using X-ray computed tomography (CT) in partially saturated gravel and made quantitative measurements of diffusion at multiple water contents using two different techniques. In the first, diffusion coefficients of KCl in 2- to 4-mm granular tuff at multiple water contents were calculated from electrical conductivity (EC) measurements using the Nernst-Einstein equation. In the second, we used laser ablation with inductively coupled plasma-mass spectrometry (LA/ICP-MS) to perform microscale mapping, allowing the measurement of diffusion coefficients for a mixture of chemical tracers for tuff cubes and tetrahedrons having two contact geometries (cube-cube and cube-tetrahedron). The X-ray computed tomography images show limited contact between grains, and this could hinder the pathways for diffusive transport. Experimental results show the critical role of surface water in controlling transport pathways and hence the magnitude of diffusion. Even with a bulk volumetric water content of 1.5%, the measured solute diffusion coefficient is as low as 1.5X10 (super -14) m (super 2) s (super -1) for tuff gravel. Currently used diffusion models relating diffusion coefficients to total volumetric water content inadequately describe unsaturated diffusion behavior in porous gravel at very low water contents.

A previous attempt to identify human effects on tropopause height relied on information from 'first-generation' reanalyses of past weather observations. Climate data from these initial model-based reanalyses have well-documented deficiencies, raising concerns regarding the robustness of earlier detection work that employed these data. Here we address these concerns using information from the new second-generation ERA-40 reanalysis. Over 1979 to 2001, tropopause height increases by nearly 200 m in ERA-40, partly due to tropospheric warming. The spatial pattern of height increase is consistent with climate model predictions of the expected response to anthropogenic influences alone, significantly strengthening earlier detection results. Atmospheric temperature changes in two different satellite data sets are more highly correlated with changes in ERA-40 than with those in a first-generation reanalysis, illustrating the improved quality of temperature information in ERA-40. Our results provide support for claims that human activities have warmed the troposphere and cooled the lower stratosphere over the last several decades of the 20th century, and that both of these changes in atmospheric temperature have contributed to an overall increase in tropopause height.

AN - 66946650; 15469353 AB - [reaction: see text] Peptide p-nitroanilides are useful compounds for studying protease activity; however, the poor nucleophilicity of p-nitroaniline makes their preparation difficult. We describe a new efficient approach for the Fmoc-based synthesis of peptide p-nitroanilides using an aryl hydrazine resin. Mild oxidation of the peptide hydrazide resin yields a highly reactive acyl diazene that efficiently reacts with weak nucleophiles. We have prepared several peptide p-nitroanilides, including substrates for the Lethal Factor protease from B. anthracis.

IVUS systems form images of the medium surrounding the probe based upon ultrasonic B scans, using a straight-ray model of sound propagation. The goal of this research is to develop a wave-based imaging algorithm using diffraction tomography techniques. Given the hardware configuration and the imaging method, this system is referred to as "radial reflection diffraction tomography." Two hardware configurations are considered: a multimonostatic mode using a single transducer as described above, and a multistatic mode consisting of a single transmitter and an aperture formed by multiple receivers. In this latter case, the entire source/receiver aperture rotates about the fixed radius. Practically, such a probe is mounted at the end of a catheter or snaking tube that can be inserted into a part or medium with the goal of forming images of the plane perpendicular to the axis of rotation. An analytic expression for the multimonostatic inverse is derived, but ultimately the new Hilbert space inverse wave (HSIW) algorithm is used to construct images using both operating modes. Applications include improved IVUS imaging, bore hole tomography, and nondestructive evaluation (NDE) of parts with existing access holes.

In Lebanon, it forms a 160-km-long restraining bend responsible for the uplift of Mount Lebanon. The resulting transpression is partitioned between the offshore Tripoli-Roum thrust and the Yammouneh strike-slip fault. There are few quantitative constraints on the Quaternary slip rate along the LFS. Here we present a direct estimate of the approximately 25-ka mean slip rate on the Yammouneh fault. Mapped offsets of alluvial fans at two sites approximately 50 km apart on the eastern flank of Mount Lebanon range between 24+ or -2 and 80+ or -8 m. About 30 limestone cobbles sampled on these fans yield in situ cosmogenic (super 36) Cl exposure ages mostly between 6 and 27 ka. A statistical assessment of offsets versus ages provides bounds on the Late Pleistocene-Holocene slip rate on the fault: 3.8-6.4 mm/yr. These results are consistent with long-term geological inferences, confirming that the Yammouneh fault is the main strike-slip branch of the LFS in Lebanon. They illustrate both the potential and the difficulties of using in situ cosmogenic (super 36) Cl dating of limestone-clast fan deposits for deciphering tectonic and geomorphic processes in the Mediterranean.

Despite their close genetic relationship, they differ radically in their pathogenicity and transmission. Here, we report the complete genomic sequence of Y. pseudotuberculosis IP32953 and its use for detailed genome comparisons with available Y. pestis sequences. Analyses of identified differences across a panel of Yersinia isolates from around the world reveal 32 Y. pestis chromosomal genes that, together with the two Y. pestis-specific plasmids, to our knowledge, represent the only new genetic material in Y. pestis acquired since the the divergence from Y. pseudotuberculosis. In contrast, 149 other pseudogenes (doubling the previous estimate) and 317 genes absent from Y. pestis were detected, indicating that as many as 13% of Y. pseudotuberculosis genes no longer function in Y. pestis. Extensive insertion sequence-mediated genome rearrangements and reductive evolution through massive gene loss, resulting in elimination and modification of preexisting gene expression pathways, appear to be more important than acquisition of genes in the evolution of Y. pestis. These results provide a sobering example of how a highly virulent epidemic clone can suddenly emerge from a less virulent, closely related progenitor.

Transcriptional profiles revealed that 51, 4, and 13 respective genes and open reading frames (ORFs) on pCD, pPCP, and pMT were thermoinduced and that the majority of these genes carried by pCD were downregulated by Ca super(2+). In contrast, Ca super(2+) had little effect on chromosomal genes and ORFs, of which 235 were thermally upregulated and 274 were thermally downregulated. The primary consequence of these regulatory events is profligate catabolism of numerous metabolites available in the mammalian host.

The model investigated is the CCM3 general circulation model. We also preliminarily assess the effect of replacing cloud and convective parameterizations in a coarse-resolution (T42) model with an embedded cloud-system resolving model (CSRM). We examine both spatial patterns of seasonal-mean precipitation and daily time scale temporal variability of precipitation in the continental United States. For DJF and SON, high-resolution simulations produce spatial patterns of seasonal-mean precipitation that agree more closely with observed precipitation patterns than do results from the same model (CCM3) at coarse resolution. However, in JJA and MAM, there is little improvement in spatial patterns of seasonal-mean precipitation with increasing resolution, particularly in the southeast USA. This is because of the dominance of convective (i.e., parameterized) precipitation in these two seasons. We further find that higher-resolution simulations have more realistic daily precipitation statistics. In particular, the well-known tendency at coarse resolution to have too many days with weak precipitation and not enough intense precipitation is partially eliminated in higher-resolution simulations. However, even at the highest resolution examined here (T239), the simulated intensity of the mean and of high-percentile daily precipitation amounts is too low. This is especially true in the southeast USA, where the most extreme events occur. A new GCM, in which a cloud-resolving model (CSRM) is embedded in each grid cell and replaces convective and stratiform cloud parameterizations, solves this problem, and actually produces too much precipitation in the form of extreme events. However, in contrast to high-resolution versions of CCM3, this model produces little improvement in spatial patterns of seasonal-mean precipitation compared to models at the same resolution using traditional parameterizations.

The prehistoric dimension of human impacts on aquatic ecosystems remains relatively undescribed, particularly in North America. Here we present fossil plankton data (diatoms and rotifers), organic and inorganic carbon accumulations, and carbon isotope ratios from a 1000 yr sediment core record from Crawford Lake, Ontario, Canada. The data document increased nutrient input to Crawford Lake caused by Iroquoian horticultural activity from A.D. 1268 to 1486 and show how this increased nutrient input elevated lake productivity, caused bottom-water anoxia, and irreversibly altered diatom community structure within just a few years. Iroquoian settlement in the region declined in the fifteenth century, yet diatom communities and lake circulation never recovered to the predisturbance state. A second phase of cultural eutrophication starting in A.D. 1867, initiated by Canadian agricultural disturbance, increased lake productivity but had comparatively less impact on diatom assemblages and carbon-storage pathways than the initial Iroquoian disturbance. This study deepens our understanding of the impact of cultural eutrophication on lake systems, highlights the lasting influence of initial environmental perturbation, and contributes to the debate on the ecological impacts of density and agricultural practices of native North American inhabitants.

Several lines of evidence strongly suggest that denitrification is naturally attenuating NO (sub 3) (super -) in the confined, O (sub 2) -depleted region of the bedrock aquifer under study (Tnbs (sub 2) ): (a) both NO (sub 3) (super -) and dissolved O (sub 2) (DO) concentrations in groundwater decrease dramatically as groundwater flows from unconfined to confined aquifer conditions, (b) stable isotope signatures (i.e., delta (super 15) N and delta (super 18) O) of groundwater NO (sub 3) (super -) indicate a trend of isotopic enrichment that is characteristic of denitrification, and (c) dissolved N (sub 2) gas, the product of denitrification, was highly elevated in NO (sub 3) (super -) -depleted groundwater in the confined region of the Tnbs (sub 2) aquifer. Long-term NO (sub 3) (super -) concentrations were relatively high and constant in recharge-area monitoring wells (typically 70-100 mg NO (sub 3) (super -) /L) and relatively low and constant in the downgradient confined region (typically <0.1-3 mg NO (sub 3) (super -) /L), suggesting a balance between rates of NO (sub 3) (super -) loading and removal by denitrification. Chemolithoautotrophic denitrification with pyrite as the electron donor is plausible in the Tnbs (sub 2) aquifer, based on the low dissolved organic C concentrations (<1.5 mg/L) that could not support heterotrophic denitrification, the common occurrence of disseminated pyrite in the aquifer, and the trend of increasing SO (super 2-) (sub 4) as groundwater flows from aerobic, unconfined to anoxic, confined aquifer conditions. Nitrate sources were investigated by experimentally determining the delta (super 15) N and delta (super 18) O signatures of NO (sub 3) (super -) from three potential anthropogenic sources of NO (sub 3) (super -) at Site 300: Ba(NO (sub 3) ) (sub 2) (mock explosive), HNO (sub 3) , and photolysis of the explosive RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine). The isotopic signatures of these potential NO (sub 3) (super -) sources were markedly different than those of NO (sub 3) (super -) in Tnbs (sub 2) groundwater samples, suggesting that other sources must contribute significantly to the NO (sub 3) (super -) loading at Site 300. In particular, NO (sub 3) (super -) and NO (sub 2) (super -) resulting from RDX photolysis reflected dramatically depleted delta (super 15) N (ca. -7.4 per mil) and delta (super 18) O (ca. -25.7 per mil) values.

Methane was formed from FeO, CaCO3-calcite, and water at pressures between 5 and 11 GPa and temperatures ranging from 500 degrees C to 1,500 degrees C. The results are shown to be consistent with multiphase thermodynamic calculations based on the statistical mechanics of soft particle mixtures. The study demonstrates the existence of abiogenic pathways for the formation of hydrocarbons in the Earth's interior and suggests that the hydrocarbon budget of the bulk Earth may be larger than conventionally assumed.

While the mechanisms remain to be determined, cruciferous vegetables may act by altering the metabolism of carcinogens present in cooked food, such as the heterocyclic amine 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP). The aim of this study was to evaluate the effect of cruciferous vegetable consumption on the metabolism of PhIP in 20 non-smoking Caucasian male subjects. The study consisted of three 12-day phases, namely two periods of avoidance of cruciferous vegetables (phases 1 and 3) and a high cruciferous vegetable diet period (phase 2), when subjects ingested 250 g each of Brussels sprouts and broccoli per day. At the end of each study phase, the subjects consumed a cooked meat meal containing 4.90 mu g PhIP and urine samples were collected for up to 48 h. Cruciferous vegetable consumption significantly increased hepatic CYP1A2, as demonstrated by changes in saliva caffeine kinetics. Samples of N super(2)-hydroxy- PhIP-N super(2)-glucuronide (the major urinary metabolite of PhIP in humans), N super(2)-hydroxy-PhIP-N super(3)-glucuronide and their trideuterated derivatives (to serve as internal standards) were synthesized and a liquid chromatography-mass spectrometry-mass spectrometry method developed for their analysis. In phases 1 and 3, the excretion of N super(2)-hydroxy-N super(2)-PhIP-glucuronide in 0-48 h urine samples was six times that of N super(2)-hydroxy-PhIP-N super(3)-glucuronide. Cruciferous vegetable consumption significantly increased the urinary excretion of N super(2)-hydroxy-PhIP-N super(2)-glucuronide in 0-48 h urine samples to 127 and 136% of levels observed in phases 1 and 3, respectively. In contrast, the urinary excretion of N super(2)-hydroxy-PhIP-N super(3)-glucuronide was unchanged. While the urinary excretion of both PhIP metabolites accounted for [approx]39% of the PhIP dose in phases 1 and 3, they accounted for [approx]49% of the dose in phase 2. This study demonstrates that cruciferous vegetable consumption can induce both the phase I and II metabolism of PhIP in humans.

Using a paired-plot design, we sought to determine the effects of long-term elevated N on the stability of five organic-matter pools: organic horizons (Oe+a), whole mineral soil (WS), mineral soil fractions including the light fraction (LF), heavy fraction (HF), and a physically recombined fraction (RF). These substrates were incubated for 300 days, and respiration, mineralized N, and active microbial biomass were measured. Samples with elevated N gave 15% lower cumulative respiration for all five substrates. Over the 300-day incubation, the Oe+a gave twice the cumulative respiration (g C kg super(-1) initial C) as the LF, which gave slightly higher respiration than the HF. Respiration was 35% higher for the WS than for the RF. Mineralized N was similar between N treatments and between the LF and HF. Net N mineralized by the LF over the course of the 300-day incubation decreased with higher C:N ratio, due presumably to N immobilization to meet metabolic demands. The pattern was opposite for HF, however, which could be explained by a release of N in excess of metabolic demands due to recalcitrance of the HF organic matter. Mineralized N increased with respiration for the HF but showed no pattern, or perhaps even decreased, for the LF. WS and RF showed decreasing active microbial biomass near the end of the incubation, which corresponded with decreasing respiration and increasing nitrate. Our results show that long-term elevated N stabilized organic matter in whole soil and soil fractions.

Studies have shown that in humans UGT1A-mediated glucuronidation is an important pathway in the detoxification of food-borne carcinogenic heterocyclic amines. The biotransformation of 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP), the most mass abundant heterocyclic amine found in cooked meats, is highly dependent on cytochrome P4501A2 hydroxylation followed by UGT-catalyzed glucuronidation of the N-hydroxy-PhIP reactive intermediate. To determine which UGT1A proteins are involved in the glucuronidation of N-hydroxy-PhIP, microsomal preparations from baculovirus-infected insect cells that express all of the known functional human UGT1A isozymes (UGT1A1, -1A3, -1A4, -1A6, -1A7, - 1A8, -1A9, and -1A10) were exposed to N-hydroxy-PhIP and the reaction products were isolated by HPLC. All UGT1A proteins except UGT1A6 showed some degree of activity toward N-hydroxy-PhIP. The formation of both N-hydroxy-PhIP-N super(2)-glucuronide and N-hydroxy-PhIP-N3-glucuronide was both time- and substrate concentration-dependent. UGT1A1 was the most efficient in converting N-hydroxy-PhIP to both conjugates producing five times more of the N super(2)-conjugate than UGT1A4, the next most active UGT, and 286 times more than UGT1A7, the least active UGT. With an apparent K sub(m) of 52 mu M and a K sub(cat) of 114 min super(-1), UGT1A1 was also the most catalytically efficient in forming N-hydroxy-PhIP-N super(2)-glucuronide. The catalytic efficiency for N-hydroxy-PhIP-N3-glucuronide formation was 8, 10, and 6 times lower for UGT1A1, -1A4, and -1A8, respectively, when compared to the K sub(cat) values of N-hydroxy-PhIP-N super(2)-glucuronide formation. These results clearly show that UGT1A1 has the highest specificity for glucuronidating N-hydroxy-PhIP. Polymorphic expression resulting in decreased UGT1A1 activity in humans can cause reduced rates of glucuronidation, which can change the metabolic ratio between bioactivation and detoxification to favor bioactivation. This change will increase the susceptibility to the deleterious effects from PhIP exposure because the capacity to form nontoxic N-hydroxy-PhIP glucuronide conjugates will be diminished.

We use selected stations in the seismic network of the eastern Alps. A detailed regional attenuation function derived by Malagnini et al. (2002) for the region is used to correct the vertical and horizontal S-wave spectra. These corrections account for the gross path effects (i.e., all distance-dependent effects), although the source and site effects are still present in the distance-corrected spectra. The main goal of this study is to isolate the absolute site effect (as a function of frequency) by removing the source spectrum (moment-rate spectrum) from the distance-corrected S-wave spectra. Typically, removing the S-wave source spectrum is difficult because of inadequate corrections for the source radiation pattern, directivity, and random interference. In addition to complexities near the source, 2D and 3D structure beneath the recording site will result in an azimuth-dependent site effect. Since the direct wave only samples a narrow range in takeoff and backazimuth angles, multistation averaging is needed to minimize the inherent scatter. Because of these complicating effects, we apply the coda methodology outlined by Mayeda et al. (2003) to obtain stable moment-rate spectra. This methodology provides source amplitude and derived source spectra that are a factor of 3-4 times more stable than those derived from direct waves. Since the coda is commonly thought of as scattered energy that samples all ray parameters and backazimuths, it is not very sensitive to the source radiation pattern and 3D structure. This property makes it an excellent choice for use in obtaining average parameters to describe the source, site, and path effects in a region. Due to the characteristics of the techniques used in this study, all the inverted quantities are azimuthally averaged, since the azimuthal information is lost in the processing. Our results show that (1) all rock sites exhibited deamplification phenomena due to absorption at frequencies ranging between 0.5 and 12 Hz (the available bandwidth), on both the horizontal and vertical components; (2) rock-site transfer functions showed large variability at high-frequency; (3) vertical-motion site transfer functions show strong frequency dependence; (4) horizontal-to-vertical (H/V) spectral ratios do not reproduce the charactersitics of the true horizontal site transfer functions; and (5) traditional, relative site terms obtained by using reference rock sites can be misleading in inferring the behaviors of true site transfer functions, since most rock sites have nonflat responses due to shallow heterogeneities resulting from varying degrees of weathering. Our stable source spectra are used to estimate the total radiated seismic energy and to compare against similar results obtained for different regions of the world. We find that the earthquakes in this region exhibit nonconstant dynamic stress drop scaling, which gives further support for a fundamental difference in rupture dynamics between small and large earthquakes.

Although sophisticated laboratory instruments exist for the analysis of Stardust samples, techniques for the recovery of particles and particle residues from aerogel collectors remain primitive. Here, we describe our recent progress in developing techniques for extracting small volumes of aerogel, which we have called "keystones," which completely contain particle impacts but minimize the damage to the surrounding aerogel collector. These keystones can be fixed to custom-designed micromachined silicon fixtures (so called "microforklifts"). In this configuration, the samples are self-supporting, which can be advantageous in situations where interference from a supporting substrate is undesirable. The keystones may also be extracted and placed onto a substrate without a fixture. We have also demonstrated the capability of homologously crushing these unmounted keystones for analysis techniques that demand flat samples.

Here we use in situ (super 36) Cl surface exposure dating of exposed bedrock fault scarps to determine earthquake time-slip histories and to quantify slip rates over the last several thousand years. This information allows us to delineate the seismic history of normal faulting within the Mediterranean area over that time period.We have studied the limestone scarp produced by the Magnola fault in the Central Apennines, Italy. The Magnola fault, in the Fucino area, is an active, 15-km long, normal fault striking WNW and dipping SSW. The range front morphology, characterised by steep triangular facets separated by V-shaped valleys and wine-glass canyons, suggests that the Magnola fault has been active for at least the last several hundred thousand years. At the base of the facets, the fault cuts limestone bedrock to produce a well-preserved normal fault scarp 10 to 12 m high.The distribution of (super 36) Cl concentration versus the height along that scarp is best explained by a minimum of five and a maximum of seven successive earthquake exhumations, with slips varying between 1.5 and 3 m. An age of approximately 5 ka at the base of the scarp and of approximately 12 ka at the top yields a slip rate of approximately 0.8 mm/year. The absence of any event on this fault during the last 5000 years suggests either that a future event is imminent on the Magnola fault or that the fault has entered a quiescent period with much longer recurrence time. Our study confirms that the Magnola fault scarp is post-glacial and supports the hypothesis that similar scarps in the Mediterranean are also post-glacial.

The radiocarbon measurements require that a large fraction of seawater bicarbonate originally present in the downwelled fluid be removed during hydrothermal circulation. The Endeavour Segment is devoid of overlying sediments and has shown no observable signs of surficial magmatic activity during the previous 20 years of ongoing studies. The appearance of isotopically heavy, radiocarbon dead CO (sub 2) after a 1999 earthquake swarm indicate that this earthquake event was magmatic in origin. Evidence for the removal of seawater bicarbonate is a significant find because many studies to date have corrected CO (sub 2) data based on the presumption of the presence of seawater bicarbonate. Utilizing both stable and radiocarbon measurements there is some evidence of a sedimentary source of carbon at Endeavour. These findings, which represent the first temporally coherent set of radiocarbon measurements from hydrothermal vent fluids, demonstrate the utility of radiocarbon analysis in hydrothermal studies.

Our 42 study sites encompass widely varying climatic and erosional regimes, with mean annual temperatures ranging from 2 to 25 degrees C, average precipitation ranging from 22 to 420 cm.year (super -1) , and denudation rates ranging from 23 to 755 t.km (super -2) .year (super -1) . Long-term chemical weathering rates range from 0 to 173 t.km (super -2) year (super -1) , in several cases exceeding the highest granitic weathering rates on record from previous work. Chemical weathering rates are highest at the sites with rapid denudation rates, consistent with strong coupling between rates of chemical weathering and mineral supply from breakdown of rock. A simple empirical relationship based on temperature, precipitation and long-term denudation rates explains 89-95% of the variation in long-term weathering rates across our network of sites. Our analysis shows that, for a given precipitation and temperature, chemical weathering rates increase proportionally with fresh-material supply rates. We refer to this as "supply-limited" weathering, in which fresh material is chemically depleted to roughly the same degree, regardless of its rate of supply from breakdown of rock. The temperature sensitivity of chemical weathering rates is two to four times smaller than what one would expect from laboratory measurements of activation energies for feldspar weathering and previous inter-comparisons of catchment mass-balance data from the field. Our results suggest that climate change feedbacks between temperature and silicate weathering rates may be weaker than previously thought, at least in actively eroding, unglaciated terrain similar to our study sites. To the extent that chemical weathering rates are supply-limited in mountainous landscapes, factors that regulate rates of mineral supply from erosion, such as tectonic uplift, may lead to significant fluctuations in global climate over the long term.

It is a multi-organ carcinogen in rodents forms adducts and with DNA and protein. Although protein adducts are not thought to be involved in cancer development, they may be useful as internal dosimeters of PhIP exposure and bioactivation. Towards the goals of characterizing the adducts formed in humans and the development of an assay for quantitation of adduct levels, we have characterized a peptide adduct formed by the putative genotoxic metabolite, N-acetoxy-PhIP. A model peptide with the internal sequence Leu-Gln-Lys-Cys- Pro-Tyr, which is homologous to a potential target sequence for HCAs in human serum albumin, was reacted with N-acetoxy-PhIP and an adduct was identified and further characterized by LC-ESI-MS/MS. N-acetoxy-PhIP is covalently bound to the peptide via cysteine and the exocyclic amino group of PhIP. Future work is needed to establish if this adduct is formed and is stable in vivo in humans following exposure to PhIP.

The stoichiometry of the net reaction, Fe super(0) + CO sub(2) + H sub(2)O arrow right FeCO sub(3) + H sub(2), and assumptions about reaction rates, reactant and product prices/values and overhead costs suggest that CO sub(2) might be mitigated at a net profit in excess of $30/tonne CO sub(2). The principle profit center of the process would be hydrogen production, alone providing a gross income of >$160/tonne CO sub(2) reacted. However, the realization of such fuel cell economics depends on a number of parameters including: (1) the rate at which the reaction can be sustained, (2) the areal and volumetric density with which H sub(2) and electricity can be produced, (3) the purity of the H sub(2) produced, (4) the transportation costs of the reactants (Fe, CO sub(2) and H sub(2)O) and products (FeCO sub(3) or Fe(HCO sub(3)) sub(2)) to/from the cells and (5) the cost/benefit trade-offs of optimizing the preceding variables in a given market and regulatory environment. Because of the carbon intensity of conventional iron metal production, a net carbon sequestration benefit for the process can be realized only when waste (rather than new) iron and steel are used as electrodes and/or when Fe(HCO sub(3)) sub(2) is the end product. The used electrolyte could also provide a free source of Fe super(2+) ions for enhancing iron-limited marine photosynthesis and, thus, greatly increasing the CO sub(2) sequestration potential of the process. Alternatively, the reaction of naturally occurring iron oxides (iron ore) with CO sub(2) can be considered for FeCO sub(3) formation and sequestration, but this foregoes the benefits of hydrogen and electricity production. Use of Fe/CO sub(2) fuel cells would appear to be particularly relevant for fossil fuel gasification/steam reforming systems given the highly concentrated CO sub(2) they generate and given the existing infrastructure they provide for producing and handling H sub(2) and/or electricity.

Here, results from proteomic characterization of host response following exposure to Yersinia pestis, the causative agent of plague, and to two near neighbors, Yersinia pseudotuberculosis and Yersinia enterocolitica, are reported. Human monocyte-like cells were chosen as a model for macrophage immune response to pathogen exposure. Two-dimensional electrophoresis followed by mass spectrometry was used to identify host proteins with differential expression following exposure to these three closely related Yersinia species. This comparative proteomic characterization of host response clearly shows that host protein expression patterns are distinct for the different pathogen exposures, and contributes to further understanding of Y. pestis virulence and host defense mechanisms. This work also lays the foundation for future studies aimed at defining biomarkers for presymptomatic detection of plague.

AN - 66688277; 15238225 AB - Efficient recognition and repair of DNA damage is essential for maintaining genomic integrity. Tissues and cell types within tissues appear to vary in both DNA damage susceptibilities and cancer incidences, yet the molecular mechanisms underlying these differences are not well understood. The purpose of this study was to characterize the baseline transcription profiles of selected genes involved in DNA damage recognition and repair processes among several tissues of healthy adult B6C3F1 mice (testis, brain, liver, spleen and heart), which are routinely used by the National Toxicology Program (NTP) to conduct long-term chemical carcinogenicity studies. Stress response, damage control and DNA repair-associated genes were differentially expressed among the tissues examined. Overall, stress response genes exhibited the greatest variation among tissues with the highest expression in liver and heart while DNA repair genes exhibited the least variation. Damage control genes associated with cell cycle regulation and DNA repair genes generally had the highest expression in testis. The expression levels of several genes were rank correlated with the spontaneous cancer incidences among these tissues. Variations in basal expression of DNA damage recognition and repair-associated genes among healthy tissues may contribute to their differential response to genotoxic agents and susceptibility to genetic disease.

AN - 66671306; 15228315 AB - An automated sample preparation module, based upon sequential injection analysis (SIA), has been developed for use within an autonomous pathogen detection system. The SIA system interfaced aerosol sampling with multiplexed microsphere immunoassay-flow cytometric detection. Metering and sequestering of microspheres using SIA was found to be reproducible and reliable, over 24-h periods of autonomous operation. Four inbuilt immunoassay controls showed excellent immunoassay and system stability over five days of unattended continuous operation. Titration curves for two biological warfare agents, Bacillus anthracis and Yersinia pestis, obtained using the automated SIA procedure were shown to be similar to those generated using a manual microtiter plate procedure.

Measured in samples from bedrock fluvial terraces, 10-beryllium shows that both the Susquehanna and Potomac Rivers incised 10- to 20-meter-deep gorges along steep, convex lower reaches during the last glacial cycle. This short-lived pulse of unusually rapid downcutting ended by 13,000 to 14,000 years ago. The timing and rate of downcutting are similar on the glaciated Susquehanna and unglaciated Potomac Rivers, indicating that regional changes, not simply glacial meltwater, initiated incision.

Benthic foraminiferal oxygen isotope record and accelerator mass spectrometry (AMS) (super 14) C data provide the basis for the core age chronology. Planktonic and benthic foraminiferal delta (super 18) O and delta (super 13) C measurements, magnetic susceptibility, ice rafted debris and coarse fraction content, carbonate and organic carbon content, and diatom and pollen spectra show major changes in regional climate, sea surface conditions, ice extent and sedimentary regime, which are correlated with the global glacial-interglacial changes of marine isotope stages (MIS) 1 through 5.3. Regional cooling and intensification of winter sea ice formation during the last glaciation increased the northern shelf surface water density and Sea of Okhotsk Intermediate Water (SOIW) formation. In addition to major Milankovitch-scale changes, lithological, geochemical and paleontological indices also show suborbital oscillations in Okhotsk Sea hydrology, sedimentation and regional climate. These shorter-term oscillations are characterized by coupled maxima in ice rafted debris and sediment coarse fraction (lithodynamic indices, LDI) values, and most are associated with cold events involving enhanced winter ice formation and intensification of SOIW and North Pacific intermediate water (NPIW) formation. The terminations of LDI maxima were induced by climate warming and reductions in ice formation and were accompanied by sharp decreases in planktonic foraminiferal delta (super 18) O. During the glacial terminations of MIS 2 and 4, however, the onset of suborbital-scale LDI maxima occurs close to sharp negative delta (super 18) O shifts in planktonic foraminifera (delta (super 18) Opf) associated with climate warming. In these special cases, the LDI maxima occurred under warm climate and rising sea levels and did not lead to increases in SOIW or NPIW ventilation.

We analyzed one hundred nineteen 1-cm-thick samples for pollen and algae from a set of cores that span the past 7630 years. The early middle Holocene, 7600 to 6300 cal yr B.P., was found to be the driest period, although it included one short but intense wet phase. We suggest that Lake Tahoe was below its rim for most of this period, greatly reducing the volume and depth of Pyramid Lake. Middle Holocene aridity eased between 5000 and 3500 cal yr B.P. and climate became variable with distinct wet and dry phases. Lake Tahoe probably spilled intermittently during this time. No core was recovered that represented the period between 3500 and 2600 cal yr B.P. The past 2500 years appear to have had recurrent persistent droughts. The timing and magnitude of droughts identified in the pollen record compares favorably with previously published delta (super 18) O data from Pyramid Lake. The timing of these droughts also agrees with the ages of submerged rooted stumps in the Eastern Sierra Nevada and woodrat midden data from central Nevada. Prolonged drought episodes appear to correspond with the timing of ice drift minima (solar maxima) identified from North Atlantic marine sediments, suggesting that changes in solar irradiance may be a possible mechanism influencing century-scale drought in the western Great Basin.

However, the physical mechanism by which magnesium alters the external form of calcite has remained controversial due to a lack of direct experimental insight. Here we use in situ AFM observations of step dynamics and growth-hillock morphology to resolve the role of Mg (super 2+) in governing calcite surface morphologies. We show that Mg (super 2+) directly modifies the surface morphology of calcite as a consequence of differential interaction with four crystallographically controlled step directions. Step-specific interactions are especially evident at low Mg/Ca ratios in solution, where steps with acute step-edge geometries ([441]- and [481]-) are observed to be rough while obtuse steps ([441]+ and [481]+) remain smooth. Higher Mg/Ca solution ratios cause the edges of both step-types to become rough and the growth spiral to approach an elliptical form. During this process, new [421] step directions are generated by decreased growth velocities at the intersection of the + or - directions. As these steps flow along the [010] vector, they accumulate and result in the formation of pseudofacets with an orientation that approximates a (010) face. We propose that this phenomenon is the result of strain at the intersection of nonequivalent step-types, resulting in differential Mg (super 2+) incorporation across the boundary between those steps. This hypothesis is supported by estimates of the incorporated strain as well as observations of growth-hillock recovery from impurity poisoning that indicate the presence of "remembered" strain at the boundary of the nonequivalent step-types. The results of this study offer a plausible molecular-scale explanation for elongate calcite crystals that are commonly observed in sedimentary environments. This novel explanation for habit modification of calcite by impurities arises from step-specific impurity interactions rather than the face-specific interactions commonly assumed in previous models (Folk 1974; Lahann 1978).

The interpretation of these seismological models in terms of chemical composition and temperature thus relies on the knowledge of the chemical composition, structure and elastic properties of some candidate materials relevant to geophysics. We will describe some recent advances in experimental mineral physics which yield essential information on the elastic properties of pertinent materials of Earth's mantle and core. In particular, we show that inelastic X-ray scattering (IXS) proves to be a well suited spectroscopic technique for the study of phonon dispersion in materials under high pressure. Inelastic scattering experiments carried out on polycrystalline samples provide measurements of orientationally averaged longitudinal acoustic velocities whereas investigations on single crystals yield elastic moduli. Such a technique is thus highly interesting for mineral physicists and offers a great potential in providing essential elastic data and their pressure and/or temperature dependence on most compounds of geophysical interest.

Phospholipid fatty acid analysis revealed that approximately 104-105 viable cells per gram of dry rock are extant, and water availability was shown to be the primary factor limiting microbial growth in situ. Phosphate and carbon limitation, however, also suppress final cell densities by at least one order of magnitude under saturated conditions. Despite these limiting factors, significant growth of aerobic chemoheterotrophic microorganisms was shown to occur in unconcentrated simulated groundwater with or without addition of a reduced carbon source (7 x 10 super(7) and 8 x 10 super(6) planktonic cells/mL, respectively), indicating that when water becomes available in the repository environment, microbial growth will ensue. Organisms that were isolated from stationary cultures grown from Yucca Mountain rock in concentrated and unconcentrated simulated groundwaters showed significant 16S rDNA sequence divergence from reference organisms. Different (but related) organisms were isolated from concentrated and unconcentrated groundwater-grown cultures. Generally, as experimental conditions approached those expected to be encountered in situ, the organisms isolated were more divergent from reference organisms. Organisms that were isolated have metabolic properties that could allow them to be active and grow within the repository environment if water availability is sufficient.

One solution is to study the gene expressed at a single ectopic site in cis. We have designed and constructed a vector that allows homologous recombination into a gene encoding a frame-shifted IS1016-V6 protein in the Haemophilus influenzae Rd KW20 chromosome (HI1018). This site is the location of the 35 kilobase capsule locus in encapsulated type b and d strains.

AN - 71920633; 15138037 AB - Carcinogenic heterocyclic amines are produced from overcooked foods and are highly mutagenic in most short-term test systems. One of the most abundant of these amines, 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP), induces breast, colon and prostate tumors in rats. Human dietary epidemiology studies suggest a strong correlation between either meat consumption or well-done muscle meat consumption and cancers of the colon, breast, stomach, lung and esophagus. For over 20 years our laboratory has helped define the human exposure to these dietary carcinogens. In this report we describe how various environmental exposures may modulate the risk from exposure to heterocyclic amines, especially PhIP. To assess the impact of foods on PhIP metabolism in humans, we developed an LC/MS/MS method to analyze the four major PhIP urinary metabolites following the consumption of a single portion of grilled chicken. Adding broccoli to the volunteers' diet altered the kinetics of PhIP metabolism. At the cellular level we have found that PhIP itself stimulates a significant estrogenic response in MCF-7 cells, but even more interestingly, co-incubation of the cells with herbal teas appear to enhance the response. Numerous environmental chemicals found in food or the atmosphere can impact the exposure, metabolism, and cell proliferation response of heterocyclic amines.

AN - 71947601; 15152935 AB - A new radiation phantom with humanoid shape and adjustable thickness (RPHAT) has been developed. Unlike the RANDO phantom which is a fixed thickness, this newly designed phantom has adjustable thickness to address the range of thicknesses of real-world patients. RPHAT allows adjustment of the body thickness by being sliced in the coronal (instead of axial) direction. Centre slices are designed so that more sections can be added or removed while maintaining the anthropomorphic shape. A prototype of the new phantom has been successfully used in a study investigating peripheral dose delivery, where the amount of scatter within the patient, and therefore the patient thickness, plays a critical role in dose deposition. This newly designed phantom is an important tool to improve the quality of radiation therapy.

AN - 71903586; 15107500 AB - Clostridium botulinum neurotoxins (BoNTs), the most potent toxins known, disrupt neurotransmission through proteolysis of proteins involved in neuroexocytosis. The light chains of BoNTs are unique zinc proteases that have stringent substrate specificity and require exceptionally long substrates. We have determined the crystal structure of the protease domain from BoNT serotype A (BoNT/A). The structure reveals a homodimer in a product-bound state, with loop F242-V257 from each monomer deeply buried in its partner's catalytic site. The loop, which acts as a substrate, is oriented in reverse of the canonical direction for other zinc proteases. The Y249-Y250 peptide bond of the substrate loop is hydrolyzed, leaving the Y249 product carboxylate coordinated to the catalytic zinc. From the crystal structure of the BoNT/A protease, detailed models of noncanonical binding and proteolysis can be derived which we propose are also consistent with BoNT/A binding and proteolysis of natural substrate synaptosome-associated protein of 25 kDa (SNAP-25). The proposed BoNT/A substrate-binding mode and catalytic mechanism are markedly different from those previously proposed for the BoNT serotype B.

AN - 71902930; 14735274 AB - Direct measurement of tritium atoms by accelerator mass spectrometry (AMS) enables rapid low-activity tritium measurements from milligram-sized samples and permits greater ease of sample collection, faster throughput, and increased spatial and/or temporal resolution. Because existing methodologies for quantifying tritium have some significant limitations, the development of tritium AMS has allowed improvements in reconstructing tritium exposure concentrations from environmental measurements and provides an important additional tool in assessing the temporal and spatial distribution of chronic exposure. Tritium exposure reconstructions using AMS were previously demonstrated for a tree growing on known levels of tritiated water and for trees exposed to atmospheric releases of tritiated water vapor. In these analyses, tritium levels were measured from milligram-sized samples with sample preparation times of a few days. Hundreds of samples were analyzed within a few months of sample collection and resulted in the reconstruction of spatial and temporal exposure from tritium releases. Although the current quantification limit of tritium AMS is not adequate to determine natural environmental variations in tritium concentrations, it is expected to be sufficient for studies assessing possible health effects from chronic environmental tritium exposure.

AN - 71899616; 15123790 AB - The human FANCG/XRCC9 gene, which is defective in Fanconi anemia complementation group G (FA-G) cells, was first cloned by genetic complementation of the mitomycin C (MMC) sensitivity of CHO mutant UV40. The CHO NM3 mutant was subsequently assigned to the same complementation group. The parental AA8 CHO cells are hemizygous at the FancG locus, and we identified frameshift mutations that result in N-terminal truncations of the protein in both UV40 and NM3. Hypersensitivity to DNA cross-linking agents, such as MMC, typically characterizes FA cells. By introducing the native CHO FancG gene into mutant NM3, we demonstrate that hamster FancG fully corrects the 3-fold sensitivity to methyl methanesulfonate (MMS) as well as the 10-fold sensitivity to MMC, whereas resistance to ionizing radiation did not increase appreciably. In contrast, hamster cDNA transformants showed incomplete correction for both MMC and MMS sensitivity. The constitutively expressed FancG protein is present in the cytoplasmic, nuclear and chromatin fractions. FancG protein levels and subcellular localization do not change appreciably as a function of cell cycle position. Our results are consistent with roles of FancG in both the nuclear and cytoplasmic compartments to maintain genomic stability in response to various genotoxic agents.

Melilite in some CAIs is replaced by spinel and Al-diopside and/or by anorthite, whereas spinel-pyroxene assemblages in CAIs and AOAs appear to be replaced by anorthite. Forsterite grains in several AOAs are replaced by low-Ca pyroxene. None of the CAIs or AOAs show evidence for Fe-alkali metasomatic or aqueous alteration. The mineralogy, textures, and bulk chemistry of most Acfer 094 refractory inclusions are consistent with their origin by gas-solid condensation and may reflect continuous interaction with SiO and Mg of the cooling nebula gas. It appears that only a few CAIs experienced subsequent melting. The Al-rich chondrules (ARCs; >10 wt% bulk Al (sub 2) O (sub 3) ) consist of forsteritic olivine and low-Ca pyroxene phenocrysts, pigeonite, augite, anorthitic plagioclase, + or -spinel, FeNi-metal, and crystalline mesostasis composed of plagioclase, augite and a silica phase. Most ARCs are spherical and mineralogically uniform, but some are irregular in shape and heterogeneous in mineralogy, with distinct ferromagnesian and aluminous domains. The ferromagnesian domains tend to form chondrule mantles, and are dominated by low-Ca pyroxene and forsteritic olivine, anorthitic mesostasis, and Fe,Ni-metal nodules. The aluminous domains are dominated by anorthite, high-Ca pyroxene and spinel, occasionally with inclusions of perovskite; have no or little FeNi-metal; and tend to form cores of the heterogeneous chondrules. The cores are enriched in bulk Ca and Al, and apparently formed from melting of CAI-like precursor material that did not mix completely with adjacent ferromagnesian melt. The inferred presence of CAI-like material among precursors for Al-rich chondrules is in apparent conflict with lack of evidence for melting of CAIs that occur outside chondrules, suggesting that these CAIs were largely absent from chondrule-forming region(s) at the time of chondrule formation. This may imply that there are several populations of CAIs in Acfer 094 and that mixing of "normal" CAIs that occur outside chondrules and chondrules that accreted into the Acfer 094 parent asteroid took place after chondrule formation. Alternatively, there may have been an overlap in the CAI- and chondrule-forming regions, where the least refractory CAIs were mixed with Fe-Mg chondrule precursors. This hypothesis is difficult to reconcile with the lack of evidence of melting of AOAs which represent aggregates of the least refractory CAIs and forsterite grains.

Techniques that can help better characterize particulate matter are required to better understand the constituents, causes, and sources of PM sub(2.5) aerosols. Measurement of the super(14)C/C ratio of the PM sub(2.5) aerosols, the absence of super(14)C in fossil carbon materials, and the known super(14)C/C levels in contemporary carbon materials allow the use of a two-component model to derive contemporary and fossil carbon contents of the particulate matter. Such data can be used to estimate the relative contributions of fossil fuels and biogenic aerosols to the total aerosol loading.

AN - 85377219; pmid-15101641 AB - Time-reversal (T/R) communications is a new application area motivated by the recent advances in T/R theory. Although perceived by many in signal processing as simply an application of matched-filter theory, a T/R receiver offers an interesting solution to the communications problem for a reverberant channel. In this paper, the performance of various realizations of the T/R receiver for an acoustic communications experiment in air is described along with its associated processing. The experiment is developed to evaluate the performance of point-to-point T/R receivers designed to extract a transmitted information sequence propagating in a highly reverberant environment. It is demonstrated that T/R receivers are capable of extracting the transmitted coded sequence from noisy microphone sensor measurements with zero-symbol error. The processing required to validate these experimental results is discussed. These results are also compared with those produced by an equivalent linear equalizer or inverse filter, which provides the optimal solution when it incorporates all of the reverberations.

Four ice avalanches were identified on the north slope of the Burhan Budai Shan several kilometers east of the Kunlun Pass, and two were identified on the south slope of the eastern Yuxi Feng, which is approximately 50 km west of the Kunlun Pass. These ice avalanches originated from steep-sided ice caps and progressed over and past the termini of outlet valley glaciers. In the Burhan Budai Shan, the ice avalanches comprised ice and snow that reached 2-3 km down valley beyond the snouts of the contemporary glaciers. Detailed study of the largest ice avalanche (B2) shows that the initial movement over the contemporary glacier was turbulent in nature, having a velocity >35 ms (super -1) . Beyond the contemporary glacier, the ice avalanche was confined within steep valley walls and entrenched paraglacial fans. Before coming to rest, this ice avalanche moved as a Bingham plastic flow at a velocity of < or =21 ms (super -1) . These ice avalanches transported little rock debris, and it is thus unlikely that they are important in contributing to the landscape evolution of this region. Yet, given the appropriate geologic and climatic conditions, ice avalanching may be an important process in the landscape evolution of high mountainous terrains. The frequency of such events is unknown, but such phenomena may become more common in the future as a consequence of increased glacier and slope instability caused by human- induced climate change. Ice avalanches, therefore, likely constitute a significant geologic hazard in the near future.

Geochemical tracer techniques including stable isotopes of water, tritium/helium-3 (T/ (super 3) He) dating, and deliberate gas tracer experiments are ideally suited for these investigations. These tracers were used to evaluate flow near an artificial recharge site in northern Orange County, California, where approximately 2.5X10 (super 8) m (super 3) (200,000 acre-feet) of water are recharged annually. T/ (super 3) He ages show that most of the relatively shallow ground water within 3 km of the recharge facilities have apparent ages 20 years at approximately 6 km. Gas tracer experiments using sulfur hexafluoride and xenon isotopes were conducted from the Santa Ana River and two spreading basins. These tracers were followed in the ground water for more than two years, allowing subsurface flow patterns and flow times to be quantified. Results demonstrate that mean horizontal ground water velocities range from 4 km/year. The leading edges of the tracer patch moved at velocities about twice as fast as the center of mass. Leading edge velocities are important when considering the potential transport of microbes and other "time sensitive" contaminants and cannot be determined easily with other methods. T/ (super 3) He apparent ages and tracer travel times agreed within the analytical uncertainly at 16 of 19 narrow screened monitoring wells. By combining these techniques, ground water flow was imaged with time scales on the order of weeks to decades.

Identification of a particular mineral or amorphous solid in a heterogeneous mixture by XAS depends on the spectral uniqueness of the element in the bonding environment associated with a component, and on absorption effects from the components and the matrix. A suite of 27 common, Fe-bearing reference compounds, including sulfides, carbonates, phosphates, oxides, oxyhydroxides, and phyllosilicates, was analyzed to empirically assess the utility of X-ray absorption near-edge structure (XANES) and extended X-ray absorption fine structure (EXAFS) for identifying a particular Fe mineral (or class of minerals) in a soil or sediment mixture. We show that XANES spectral features are useful for distinguishing qualitatively among major mineral classes, but not necessarily for identifying minerals within classes. A practical detection limit (based on empirical mixtures) for most mineral classes is on the order of 5% of the total atomic Fe absorption, but detection limits vary depending on the spectral uniqueness of the components, the number of components, and the matrix. Calibration curves for Fe sulfide and non-sulfide (phyllosilicate+ or -oxide) component mixtures were made independently from the analyses of XANES and EXAFS fluorescence spectra of binary and ternary mineral mixtures (at 5% total Fe) in a quartz matrix to mimic natural sediments. Because of differences in sample and matrix absorption and fluorescence among sulfide and phyllosilicate minerals, apparent component fractions of pyrite derived from fits deviated significantly from linear binary mixtures. We show that corrections for non-linear fluorescence (as much as 20%) are particularly important for binary mineral mixtures with different densities and absorption characteristics (such as sulfides and phyllosilicates), and for mixtures with similar component abundances (i.e., far from one end-member). An application of the fluorescence calibration for XANES and EXAFS is shown for natural samples. This study points out the importance of a high-quality, experimentally consistent reference compound library, and the need for calibration of fluorescence spectra, in order to quantify accurately the component fractions of complex mixtures using XAS.

We present a novel method of estimating epicentral distance by integrating observed travel times (Lg-Pn and Sn-Pn) measured on three-component (3C) single-station data with theoretical travel times for the same phase combinations determined from 3D velocity models. Theoretical travel times for the body-wave phases are estimated using raytracing through a 3D P- and S-wave velocity model, while the travel times for Lg are estimated either using raytracing techniques or with a constant velocity determined from synthetics. Backazimuths are determined by applying polarization techniques on 3C data. The backazimuth and distance are then used to determine the epicenter for the event. The results of applying this 3D single-station location methodology to well-located events in southern Asia show mislocation errors that are typically less than 6% of the total propagation path distance.

In order to provide a quantitative basis for interpreting and predicting the distribution of aqueous species between heulandite and aqueous solutions, ion exchange equilibrium between heulandite and aqueous solutions with respect to the binary cation pairs Ca (super 2+) -K (super +) , Ca (super 2+) -Na (super +) , K (super +) -Na (super +) , K (super +) -Sr (super 2+) , Na (super +) -Sr (super 2+) , and Ca (super 2+) -Sr (super 2+) was investigated. Homoionic Ca-, K-, and Na-heulandites prepared from natural heulandite were equilibrated with 0.1 N Cl (super -) solutions containing various proportions of the cations in a given binary pair at 55 and 85 degrees C to define isotherms describing partitioning of the cations over a wide range of heulandite and solution composition with respect to the cations in each pair. In general, the experiments equilibrated rapidly, within 11 to 15 weeks at 55 degrees C and 3 to 4 weeks at 85 degrees C. The exception was the Ca (super 2+) -Sr (super 2+) binary exchange, which did not equilibrate even after 3 months at 55 degrees C and 4 weeks at 85 degrees C. Slow exchange of Sr (super 2+) for Ca (super 2+) also prohibited preparation of homoionic Sr-heulandite from the natural (Ca-rich) heulandite within 10 weeks in 2N SrCl (sub 2) solution at 90 degrees C, although near homoionic Sr-heulandite was produced by exchange of K- and Na-heulandite. Experimentally determined isotherms were used to derive equilibrium constants for the ion exchange reactions and asymmetric Margules models describing the extent of non-ideality in extraframework solid solutions in heulandite. Regressed equilibrium constants for Ca (super 2+) -Na (super +) , Ca (super 2+) -K (super +) , and K (super +) -Na (super +) binary cation pairs at 55 degrees C are internally consistent among each other (complying with the triangle rule), indicating good accuracy of these data. The maximum departure from internal consistency among the equilibrium constants for three binary pairs was 900 J per mole of charge equivalents (eq) for the 55 degrees C experiments and 2300 J eq (super -1) for the 85 degrees C experiments. The applicability of the present experimental results and thermodynamic models was assessed by calculating the composition of heulandite in Icelandic geothermal systems from known compositions using the regressed thermodynamic properties of Ca (super 2+) -Na (super +) exchange at 85 degrees C. Calculations predict an average Ca mole fraction [defined as Ca/(Ca+Na)] in heulandite of 0.74, in excellent agreement with observed compositions of heulandite from geothermal and metamorphic systems in Iceland (0.75). Thermodynamic data for heulandite ion-exchange derived in this study can be used to predict partitioning of Ca, K, Na, and Sr between heulandite and aqueous solutions in geologic systems. Because heulandite is the most effective sink for Sr in basaltic aquifers that have undergone zeolite facies metamorphism, the experimental results of this study will provide essntial data for modeling Sr transport in aquifers in low-grade metabasalts.

The aim of the CEP was to provide University campuses with site-specific assessments of their earthquake strong motion exposure, to complement estimates they obtain from consultants according to the state-of-the-practice (SOP), i.e. Building Codes (UBC 97, IBC 2000), and Probabilistic Seismic Hazard Analysis (PSHA). The Building Codes are highly simplified tools, while the more sophisticated PSHA is still somewhat generic in its approach because it usually draws from many earthquakes not necessarily related to the faults threatening the site under study. Between 1996 and 2001, the site-specific studies focused on three campuses: Riverside, San Diego, and Santa Barbara. Each campus selected 1-3 sites to demonstrate the methods and procedures used by the CEP: Rivera Library and Parking Lots (PL) 13 and 16 at UCR, Thornton Hospital, the Cancer Center, and PL 601 at UCSD, and Engineering I building at UCSB. The project provided an estimate of strong ground motions at each selected site, for selected earthquake scenarios. These estimates were obtained by using an integrated geological, seismological, geophysical, and geotechnical approach, that brings together the capabilities of campus and laboratory personnel. Most of the site-specific results are also applicable to risk evaluation of other sites on the respective campuses. The CEP studies have provided a critical assessment of whether existing campus seismic design bases are appropriate. Generally speaking, the current assumptions are not acknowledging the severity of the majority of expected motions. Eventually, both the results from the SOP and from the CEP should be analyzed, to arrive at decisions concerning the design-basis for buildings on UC campuses.

Specimens were placed between two transducers, and the resonant frequencies of vibration were measured between 0.5 and 1.4 MHz. The elastic constants determined from the measured resonant frequencies in hydrated dentin exhibited slight hexagonal anisotropy, with the stiffest direction being perpendicular to the axis of the tubules (E sub(11)=25.1 GPa). This hexagonal anisotropy was small (E sub(33)/E sub(11)=0.92), and almost disappeared when the specimens were dried. In addition, there was a pronounced anisotropy in the Poisson's ratio of wet dentin: nu sub(21)=0.45; nu sub(31)=0.29. With drying in air, this anisotropy vanished: nu sub(21)= nu sub(31)=0.29. The isotropic Young's modulus of dried dentin was 28.1 GPa. RUS shows promise for determining the elastic constants in mineralized tissues.

AN - 71766503; 15036006 AB - We devised an assay to quantify the metabolites of 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) in human urine following a single exposure to well-cooked meat. Our method uses LC/MS/MS to detect four metabolites and four deuterated internal standard peaks in a single chromatographic run. N2-OH-PhIP-N2-glucuronide was the most abundant urinary metabolite excreted by the 12 individuals who participated in our study. N2-PhIP glucuronide was the second most abundant metabolite for 8 of the 12 volunteers. The stability of PhIP metabolism over time was studied in three of the volunteers who repeated the assay eight times over a 2.5 year-period. PhIP metabolite excretion varied in each subject over time, although the rate of excretion was more constant. Our results suggest that quantifying PhIP metabolites should make future studies of individual susceptibility and dietary interventions possible. JF - Journal of chromatography.

AN - 80173168; 14585809 AB - The developmental consequences of chromosomal aberrations in embryos include spontaneous abortions, morphological defects, inborn abnormalities, and genetic/chromosomal diseases. Six germ-cell mutagens with different modes of action and spermatogenic stage sensitivities were used to investigate the relationship between the types of cytogenetic damage in zygotes with their subsequent risk of postimplantation death and of birth as a translocation carrier. Independent of the mutagen used, over 98% of paternally transmitted aberrations were chromosome type, rather than chromatid type, indicating that they were formed during the period between exposure of male germ cells and initiation of the first S phase after fertilization. There were consistent one-to-one agreements between the proportions of a) zygotes with unstable aberrations and the frequencies of dead embryos after implantation (slope = 0.87, confidence interval [CI]: 0.74, 1.16) and b) zygotes with reciprocal translocations and the frequency of translocation carriers at birth (slope = 0.74, CI: 0.48, 2.11). These findings suggest that chromosomal aberrations in zygotes are highly predictive of subsequent abnormal embryonic development and that development appears to proceed to implantation regardless of the presence of chromosomal abnormalities. Our findings support the hypothesis that, for paternally transmitted chromosomal aberrations, the fate of the embryo is already set by the end of G1 of the first cell cycle of development.

DNA repair and cancer as a paradigm. AN - 66644634; 15209414 AB - With the vast technological and informational resources increasingly available from investments in "genomics," toxicology and much of biological science, is faced with previously undreamed of opportunities and equally daunting challenges. The ability to generate the large quantities of data becoming routinely available could not be imagined a decade ago. The complexities of data analysis are increasingly the rate-limiting element in scientific advances. The expectations that these large scientific investments will reduce the incidence of human disease and improve health are very high. An emphasis on genetic variation and Toxicogenetics is expected to yield risk estimates for specific rather than average individuals and individuals with varied lifestyles and complex patterns of exposure. Examples from studies of polymorphic variation in DNA repair genes in the healthy population and cancer risk highlight the complexity and challenges of incorporating genetic variation into quantitative estimates of risk associated with environmentally relevant exposures. Similar issues exist in selecting the animal models most appropriate for predicting human risk from environmental exposures to toxic agents.

Rapid incision of approximately 0.2 mm/yr from 2.7 to ca. 1.5 Ma slowed markedly to approximately 0.03 mm/yr thereafter, likely reflecting the combined effects of a transient erosional response to Pliocene rock uplift and periodic mantling of riverbeds with glacially derived sediment in the late Quaternary. While approximately 400 m of incision has occurred in the past 2.7 m.y., outpacing interfluve erosion and thereby increasing the local relief, canyons as deep as 1.6 km existed prior to that time. These new erosion rates strengthen the case for tectonically driven late Cenozoic uplift.

Although the trapped noble gases in five DaG samples show ratios typical of solar or planetary gases, in all other DaG samples, they are dominated by atmospheric contamination, which increases with the degree of weathering. Cosmic ray exposure (CRE) ages of DaG chondrites range from approximately 1 Myr to 53 Myr. The CRE age distribution of 10 DaG L chondrites shows a cluster around 40 Myr due to four members of a large L6 chondrite shower. The CRE age distribution of 19 DaG H chondrites shows only three ages coinciding with the main H chondrite peak at approximately 7 Myr, while seven ages are <5 Myr. Two of these H chondrites with short CRE ages (DaG 904 and 908) show evidence of a complex exposure history. Five of the H chondrites show evidence of high shielding conditions, including low (super 22) Ne/ (super 21) Ne ratios and large contributions of neutron-capture (super 36) Cl and (super 41) Ca. These samples represent fragments of two or more large pre-atmospheric objects, which supports the hypothesis that the high H/L chondrite ratio at DaG is due to one or more large unrecognized showers. The (super 14) C concentrations correspond to terrestrial ages <35 kyr, similar to terrestrial ages of chondrites from other regions in the Sahara but younger than two DaG achondrites. Despite the loss of cosmogenic (super 36) Cl and (super 41) Ca during oxidation of metal and troilite, concentrations of (super 36) Cl and (super 41) Ca in the silicates are also consistent with (super 14) C ages <35 kyr. The only exception is DaG 343 (H4), which has a (super 41) Ca terrestrial age of 150+ or -40 kyr. This old age shows that not only iron meteorites and achondrites but also chondrites can survive the hot desert environment for more than 50 kyr. A possible explanation is that older meteorites were covered by soils during wetter periods and were recently exhumed by removal of these soils due to deflation during more arid periods, such as the current one, which started approximately 3000 years ago. Finally, based on the (super 26) Al/ (super 21) Ne and (super 10) Be/ (super 21) Ne systematics in 16 DaG meteorites, we derived more reliable estimates of the (super 10) Be/ (super 21) Ne production rate ratio, which seems more sensitive to shielding than was predicted by the semi-empirical model of Graf et al. (1990) but less sensitive than was predicted by the purely physical model of Leya et al. (2000).

The delta (super 13) C values of DOC in the Missouri River varied approximately 2.0 per mil over a one-year period and approximately followed mean water temperature. This suggested contribution of algae components into the DOC pool. Dissolved hydrophobic acids, which constituted approximately 50% of the DOC showed little variation and were consistent with terrestrial plant-derived material (-25 to -28 per mil). Daily mean stream flow measurements at St. Josephs and at Hermann were used to compute the fraction of water derived upstream of the State of Missouri versus that derived within State. The concentration and radiocarbon ( (super 14) C) content of DOC sampled in St. Louis exhibited strong linear correlation with fraction of discharge and were related to the marked regional climate differences between upstream (approx. 20 in rain/yr) and downstream (approx. 40 in rain/yr) of this large river system. The DOC concentration varied from 3.0 mg/L for upstream-dominated discharge to 7.0 mg/L for downstream-dominant. The dissolved hydrophobic acids in upstream discharge had (super 4) C contents as low as 87 pmc; whereas, in downstream discharge it was near 100 pmc. To better understand the (super 14) C variability, the (super 14) C content of several dissolved hydrophobic acids isolated from rivers and lakes representing various climates were measured. The (super 14) C data ranged from 77 to 130 pmc and showed a strong positive correlation with the mean annual precipitation rate (10 in/yr to 80 in/yr; proxy for net primary productivity) of the sample area. The range in calculated apparent (super 14) C ages is at least a factor of five higher than the range represented in precipitation rates, suggesting soil retention likely has a secondary role in controlling the (super 14) C variability of hydrophobic acids in water.

Organic carbon loading to the SWP is a growing concern for water utilities serving 23 million Californians owing to the potential for DOC to form harmful disinfection by-products. An accurate conceptual understanding of carbon dynamics within the Sacramento-San Joaquin Delta and SWP is critically needed to assess the impact of proposed CALFED ecosystem restoration activities (e.g., construction of in-Delta reservoirs and tidal wetlands). The 14C content of DOC was measured in riverine input to the Delta and in three agricultural drains during the spring runoff period (April 2003) and at the start of the irrigation season (June 2003). DOC fractions measured included bulk DOC and dissolved hydrophobic acids (HPOA). In the agricultural drains the 14C content of HPOA compounds and bulk DOC overlapped and ranged from 0.73 to 0.86 pmc. The 14C content of bulk DOC and HPOA fractions in riverine input to the Delta was higher, ranging from 0.96 to 1.07 pmc. The 14C content of SWP waters, ca. 1.00 pmc, was bracketed by the riverine and agricultural values and showed little variation between the two sampling dates. In contrast, mean 14C content of HPOA in the rivers increased from 0.96 to 1.08 pmc between April and June, while in the agricultural drains mean values declined slightly from 0.81 to 0.79 pmc. Using HPOA 14C content and a simple two-component mixing model we estimated that, during April 2003, 93% of the carbon in the SWP was derived from riverine inputs. During June 2003 DOC loading to the SWP was split about equally between riverine inputs and agricultural drainage.

Incision significantly accelerated beginning at the onset of the last glacial period (30 to 35 ky). A vertical transect of 4 samples, each on one prominent terrace (21 m elevation range) suggests that from >100 to approximately 32 ky, the Susquehanna incised through competent schist at 150 m below present and river discharge and sediment load were presumably elevated by glacial meltwater. Furthermore, 14 samples collected in a cross section at the upper end of the gorge yield an incision rate of 0.6 m/ky (R (super 2) = 0.94) commencing approximately 31 ky. Similarly, mean ages from numerous samples collected longitudinally along each of the terrace levels suggest incision rates between 0.6 and 0.7 m/ky beginning approximately 30 ky and ending approximately 14 ky. Alternatively, amalgamating the results of 24 samples collected in vertical transects down the fronts of 3 mid-channel islands suggest incision at 0.1 m/ky from approximately 46 to approximately 24 ky, increasing to 1.0 m/ky between approximately 21 and approximately 14 ky. The timing and rate of incision along both the glaciated Susquehanna and unglaciated Potomac Rivers (100 km south) are remarkably similar (0.8 m/ky from 37 to 13 ky) suggesting that large rivers draining the Atlantic Passive margin are responding to regional forcings likely including climate induced changes in flood frequency, sediment load, and isostasy. Passive margin incision rates we measured are less than, but approach incision rates on the Indus River (1 to 12 m/ky) in the tectonically active Himalayas (Burbank et. al, 1996; Leland et. al, 1998).

For 12 basins south of the Wisconsin glacial margin, the sediment generation (erosion) rates range from 8-19 m/My, with a mean of 13 m/My. The 10-Be based rates are positively correlated (R (super 2) = 0.5) with sediment yields obtained from USGS gaging stations at the sample sites, implying broadly consistent rates of sediment yield on decadal time scales and erosion on millennial timescales. However, this correlation does not include three Piedmont basins with sediment yields that imply erosion rates in excess of 30 m/My. These three basins are heavily farmed, including widespread use of traditional agricultural practices. Results are forthcoming for an additional 72 sediment samples, dominantly from basins <10 sq. km in area. Most of these basins are south of the Wisconsin glacial margin, have mean slopes that span a range of 20 degrees , represent three lithologies (sandstone, shale, and schist), and are distributed among the Appalachian Plateaus, Piedmont, and Valley and Ridge physiographic provinces. The results from these basins will be used to investigate relationships between sediment generation rates and GIS-measurable characteristics of the present-day landscape.

The magnitude of the oceanic reservoir age in the inland waters of the Georgia Basin and Puget Lowland of northwestern North America is inferred from radiocarbon ages on shell-wood pairs in Saanich Inlet and previously published estimates. The weighted mean oceanic reservoir correction in the early and mid Holocene is -720+ or -90 yr, slightly smaller than, but not significantly different from, the modern value. The correction in late-glacial time is -950+ or -50 yr. Valley-head sites yield higher reservoir values (-1200+ or -130 yr) immediately after deglaciation. The magnitude of the gyttja reservoir effect is inferred from pairs of bulk gyttja and plant macrofossil ages from four lakes in the region. Incorporation of old carbon into basal gyttja yields ages from bulk samples that are initially about 600 yr too old. The reservoir age declines to less than 100 yr after the first millennium of lake development. When these corrections are accounted for, dates of deglaciation and late-glacial sea-level change in the study area are pushed forward in time by more than 500 yr.

The simulations with prescribed SSTs and sea ice are available from the Atmospheric Model Intercomparison Project (AMIP), and coupled ocean-atmosphere simulations are available from the Coupled Model Intercomparison Project (CMIP). We compare CMIP runs from two coupled models sharing a common atmosphere component (but different ocean components) with the atmosphere component's AMIP run. All three simulations have similar errors that presumably originate in the atmosphere component. Replacing the observed SSTs and sea ice amounts in the AMIP simulation with the interactive submodels used in the CMIP simulations tends to degrade the level of agreement with climate observations. Increases in root-mean-square (RMS) errors, however, are mostly less than 30% and often less than 10% of the magnitude of natural climate variations. Exceptions to this rule occur mainly in the tropics, most notably for geopotential height at 500 hPa and for temperature near the tropopause. These variables show increases in RMS errors that are comparable to observational standard deviations. The coupled model simulations are taken from the end of 300 year control runs without flux "corrections" at the ocean-atmosphere interface. Their similarity to results from the prescribed SST atmosphere model implies that modern coupled models can maintain stable multicentury simulations without flux adjustments.

Different mixtures and configurations of quartz sand and 10% Na-montmorillonite clay were investigated using solutions of NaCl, CaCl (sub 2) , and deionized water. A sample containing 10% dispersed clay was also studied using fluids containing 20- and 500-ppm trichloroethylene (TCE). Each sample's electrical properties after fluid saturation were measured at frequencies between 10 (super -2) and 10 (super 6) Hz by using the four-electrode method with Ag-AgCl inner electrodes at room temperature and 412 kPa confining pressure, which corresponds to a soil depth of 15-20 m. Our results show that adding TCE had a small effect on electrical resistivity: resistivity was greater at higher concentrations of TCE. The influence of TCE on electrical properties was most prominent in plots of loss tangent as a function of frequency. These plots showed that loss-tangent peaks occurred at approximately 200 Hz and that peak and peak frequency were smaller at higher concentrations of TCE. Additional experiments were performed on a sample that contained a distinct clay layer parallel to the current flow. The electrical properties of the sample were measured as it was saturated with deionized water and CaCl (sub 2) solutions, and as an ethanol-water mixture (80:20) was flowed through the sample. Resistivity increased by about a factor of 4 as the ethanol mixture replaced the water solution. Nondestructive x-ray imaging of the sample at various stages of dewatering indicated a decrease in the thickness of the clay layer as more pore volumes of ethanol-water were flowed. Our results show that electrical measurements are useful tools for characterizing porous rocks and soils and that it is feasible to remotely detect the presence and follow the transport of contaminants such as TCE in the subsurface.

However, most of these records are compromised by chronological flaws, making problematic any comparisons with climatic interpretations based on other records (e.g., GISP2 in Greenland). We report here a high-resolution pollen record with a secure chronology constrained by 26 (super 14) C dates on terrestrial macrofossils from Steel Lake, central Minnesota. About 11.2 ka cal BP (11,000 calibrated yr before present) the late-glacial Picea forest near Steel Lake was succeeded abruptly by Pinus banksiana and/or resinosa. The Pinus forest began to open 9.4 ka cal BP with the expansion of prairie taxa, and a pine parkland or savanna prevailed until about 8 ka cal BP, when Quercus replaced Pinus to become the dominant tree in the prairie areas for 4500 yr. The close chronological control permits the correlation of key vegetational changes with those at other reliably dated sites in the eastern Dakotas and in Minnesota, suggesting that the abrupt decline of the spruce forest was time-transgressive from southwest to northeast during 2000 yr, and that the development of prairie was time-transgressive in the same direction over 2600 yr. Correlation of key pollen horizons at Steel Lake with those in the high-resolution pollen profiles of Elk Lake, ca. 50 km northwest of Steel Lake, suggests that the well-known Elk Lake varve chronology for the early Holocene is about 1000 yr too young.

The life histories of each individual animal are modeled separately. The individuals can have the status of residents or wanderers and belong to behaviorally differing groups of juveniles or adults and males or females. Their territory defending and monogamous behavior is taken into consideration. The resource, green vegetation, grows depending on seasonal climatic characteristics and is diminished due to the herbivore's grazing. Other specifics such as a varying personal energetic level due to feeding and starvation of the individuals, mating preferences, avoidance of competitors, dispersal of juveniles, as a result of site overgrazing, etc., are included in the model. We determined model parameters from real data for the species Microtus ochrogaster (prairie vole). The simulations are done for a case of an enclosed habitat without predators or other species competitors. The goal of the study is to find the relation between size of habitat and population persistence. The experiments with the model show the populations go extinct due to severe overgrazing, but that the length of population persistence depends on the area of the habitat as well as on the presence of fragmentation. Additionally, the total population size of the vole population obtained during the simulations exhibits yearly fluctuations as well as multi-yearly peaks of fluctuations. This dynamics is similar to the one observed in prairie vole field studies.

Thus, rather than evaluating the ecological impact on species in the immediate vicinity of the release, it may be more ecologically meaningful to determine if population impacts occur at the landscape level. In order to do this, the cumulative impact of all releases in the landscape under consideration must be evaluated. If the release sites are viewed as localized areas that are no longer available for use by ecological receptors (i.e., no longer part of the habitat), this can be thought of as a form of habitat fragmentation. Habitat fragmentation is typically viewed as the loss of large areas of habitat within a landscape, leaving small isolated patches of intact habitat within a hostile matrix. Small-scale contaminant releases, on the other hand, result in small uninhabitable areas within a primarily intact habitat. With this consideration in mind, we analyzed the wildlife and conservation biology literature to determine if information on habitat size requirements such as home-range or critical patch size could inform us about the potential for impact at the landscape level from release sites based on the size of the release alone. We determined that evaluating the impact of release size had to be conducted within a contextual basis (considering the existing state of the landscape). Therefore, we also reviewed the population modeling literature to determine if models could be developed to further evaluate the impact of the spatial extent of chemical releases on the landscape. We identified individual-based models linked to geographic information systems to have the greatest potential in investigating the role of release size with respect to population impacts at the landscape level.

Annual mean Delta 14C has a dynamic range of nearly 175ppt, with a total range of nearly 200ppt. Prebomb values average -56ppt and the annual mean postbomb maxima occurs in 1985 with a value of +117%. Interannual variability in the record reflects surface current variations in conjunction with surface wind changes associated with ENSO. During El Nino years the waters of the Solomon Sea reflect a stronger influence of waters advected in from the east by the SEC and less 'pure' subtropical water. This is most likely accomplished by a southward shift of the equatorward branch of the SEC during El Nino. There is an overall decrease in the relative proportion of eastern tropical water that is interpreted as a decrease in the strength and intensity of the shallow circulation of the tropical Pacific during the latter portion of the twentieth century. If validated, this secular trend bears strongly upon the rate of extratropical-tropical recirculation and the redistribution of heat and salt within the tropical Pacific.

Interest in the phenomena waxed in the 1980s, but models developed at that time remain limited by the lack of both detailed, time-resolved wet deposition pattern measurements for model confirmation and real-time rain data for model execution. Recently, new rain products have become available that can revolutionize real-time use of precipitation scavenging models on the regional scale. We have utilized a 4-km, hourly resolution precipitation data set from the Arkansas Red-Basin River Forecast Center. A standard below-cloud aerosol scavenging model has been modified to incorporate the potentially larger scavenging in heavy rain events. This paper demonstrates the model on a sample rainfall data set. The simulations demonstrate the concentrating effect of rainfall, especially heavy rain, on deposition patterns. Wet deposition played an important role in the simulated fate and transport, removing as much as 70% of the released aerosol.

Recent developments in response to threats posed by chemical and biological warfare agents. AN - 71552605; 14660116 AB - Recent terrorist events underscore the urgent need to develop a comprehensive set of health-protective cleanup standards and effective decontamination technologies for use in the restoration of civilian facilities. Accurate scientific information remains limited in the area of biological warfare agents. However, new guidelines and calculated cleanup values are emerging for initial re-entry and long-term reoccupation following use of chemical warfare agents. This article addresses airborne, soil, and surface exposures following release of G-type chemical warfare agents and VX. Cleanup goals should be tailored to the type of population that may be exposed, potential exposure times, and other scenario-specific considerations. Three different airborne concentrations are proposed for cleanup of public sector facilities. One value is recommended for initial re-entry; a more conservative value is recommended for long-term monitoring and increased public confidence; and a third, even more conservative concentration represents essentially a no-effect level for round-the-clock airborne exposure. Health-based cleanup levels are provided for contaminated residential and industrial soil. Results are presented on the outcome of a preliminary risk assessment to determine safe surface levels (e.g., walls, floors, and handrails) for cleanup after exposure to the G agents and VX. Because specific cleanup criteria for most biological warfare agents remain problematic, recommendations are made for filling the knowledge gaps.

We report here the presence of a (super 13) C depletion associated with a (super 15) N enrichment in an anhydrous interplanetary dust particle. Our observations suggest that the anomalies are carried by heteroatomic organic compounds. Theoretical models indicate that low-temperature formation of organic compounds in cold interstellar molecular clouds can produce carbon and nitrogen fractionations, but it remains to be seen whether the specific effects observed here can be reproduced.

AN - 51827042; 2004-054167 AB - Understanding the nature and composition of larger extraterrestrial bodies that may collide with the Earth is important. One source of information lies in the record of ancient impact craters, some of which have yielded chemical information as to the impacting body. Many deeply eroded craters have no remaining melt sheet or ejecta yet may contain impactor residue within basement fractures. The emplacement mechanism for fractionated siderophile residues is likely to be gaseous, although, melt droplets and some solid materials may survive. For breccia- and melt-filled fractures to contain extraterrestrial material, they must form very early in the impact process. Most current numerical models do not dwell on the formation and location of early major fractures, although, fractures in and around small craters on brittle glass exposed to hypervelocity impact in low Earth orbit have been successfully simulated. Modelling of fracture development associated with larger craters may help locate impact residues and test the models themselves.

Our study sites are distributed along a 2 km ridgeline transect that spans 2090 to 2750 m in altitude, and encompasses marked contrasts in both vegetative cover and snow depth, but is underlain by a single, roughly uniform, granodiorite bedrock. Cosmogenic nuclides in colluvial soils reveal that denudation rates vary by less than a factor of 1.4 (104-144 t/km (super 2) /yr) along this transect. Bulk elemental analyses indicate that, relative to the parent rock, soils are less intensively weathered with increasing altitude, and show little evidence of weathering-related mass losses near the top of the ridge. Chemical weathering rates decrease rapidly with increasing altitude, both in absolute terms (from 24 to 0 t/km (super 2) /yr) and as a fraction of total denudation rates (from 20 to 0%). Thus these results indicate an increasing dominance of physical erosion with altitude. The observed decrease in chemical weathering rates is greater than one would predict from the decrease in mean annual temperature using simple weathering kinetics, suggesting that weathering rates along our transect may also be affected by the progressive decline in vegetative cover and increase in snow depth with increasing altitude. These results, considered together with weathering rate measurements for a wide range of climates in the Sierra Nevada, USA, suggest that chemical weathering rates may be particularly sensitive to differences in climate at higher-altitude sites. Consistent with this hypothesis, chemical weathering rates fall virtually to zero at the highest sites on our transect, suggesting that sparsely vegetated, high-altitude crystalline terrain may often be characterized by extremely slow silicate weathering rates.

Constant Kd models for describing radionuclide retardation are not valid under these conditions because of strong competition for sorption sites by abundant Na+ ions, and because of dramatically changing solution compositions with time as the highly concentrated tank fluid becomes diluted as it mixes with infiltrating rainwater. A mechanistic multicomponent sorption model is required that can account for effects of competition and spatially and temporally variable solution compositions. To investigate the influence of the high ionic strength tank fluids on Cs (super +) migration, numerical calculations are performed using the multiphase-multicomponent reactive transport code FLOTRAN. The computer model describes reactive transport in nonisothermal, variably saturated porous media including both liquid and gas phases. Pitzer activity coefficient corrections are used to describe the high ionic strength solutions. The calculations take into account multicomponent cation exchange based on measured selectivity coefficients specific to the Hanford sediments. Solution composition data obtained from Well 299-W23-19, documenting a moderately concentrated leak from the SX-115 tank, are used to calibrate the model. In addition to exchange of cations Na (super +) , K (super +) , Ca (super 2+) , and Cs (super +) , aqueous complexing and a kinetic description of precipitation and dissolution of calcite are also included in the calculations. The fitted infiltration rate of 0.08 m yr-1, and fitted cation exchange capacity of 0.05 mol kg-1 are consistent with measured values for the Hanford sediments. A sensitivity analysis is performed for Na (super +) concentrations ranging from 5 to 20 m to investigate the mobility of Cs (super +) interacting with a highly concentrated background electrolyte solution believed to have been released from the SX-108/SX-109 tanks. The calculations indicate that during the initial period of the tank leak when Cs (super +) is associated with high Na (super +) concentrations, there is little retardation of the Cs (super +) plume. However, as time increases the Na (super +) and Cs (super +) profiles become chromatographically separated due to differences in their selectivity coefficients and dilution of the tank leak plume with infiltrating rainwater. Eventually the two species become separated spatially, and Cs (super +) becomes highly retarded and remains essentially fixed in the sediments by cation exchange. For the 20 m Na (super +) simulated tank leak, the sorbed Cs (super +) profile is in close agreement with data obtained from the slant borehole and consistent with the estimated tank supernatant concentration. The simulations suggest that natural attenuation processes should result in strong fixation of Cs (super +) in the vadose zone in spite of the release of high Na (super +) concentrations during a tank leak event.

Optical trapping immobilizes the particle while maintaining it in the center of the laser beam path and within the laser focus, thus maximizing the collection of its Raman signals. The single particle is completely isolated from other particles and substrate surfaces, therefore eliminating any unwanted background signals and ensuring that information is collected only from the selected, individual particle. In this work, an inverted confocal Raman microscope is combined with optical trapping to probe and analyze bacterial spores in solution. Rapid, reagentless detection and identification of bacterial spores with no false positives from a complex mixed sample containing polystyrene and silica beads in aqueous suspension is demonstrated. In addition, the technique is used to analyze the relative concentration of each type of particle in the mixture. Our results show the feasibility for incorporating this technique in combination with a flow cytometric-type scheme in which the intrinsic Raman signatures of the particles are used instead of or in addition to fluorescent labels to identify cells, bacteria, and particles in a wide range of applications.

This article describes a mass spectrometry-based analytical technique for the real-time and reagentless characterization of individual airborne cells without sample preparation. We characterize the mass spectral signature of individual Bacillus spores and demonstrate the ability to distinguish two Bacillus spore species, B. thuringiensis and B. atrophaeus, from one another very accurately and from the other biological and nonbiological background materials tested with no false positives at a sensitivity of 92%. This example demonstrates that the chemical differences between these two Bacillus spore species are consistently and easily detected within single cells in seconds.

AN - 66680206; 15238671 AB - This paper discusses a collaborative project (1) to demonstrate the feasibility and benefit of a system seeking early review, in a 'quasi peer review' mode, of nuclear accident plume and dose assessment predictions by four major international nuclear accident emergency response systems before release of calculations to respective national authorities followed by (2) sharing these results with responsible national/international authorities, (3) development of an affordable/accessible system to distribute results to countries without prediction capabilities and (4) utilisation for exercises and collaboration studies. The project exploits Internet browser technology and low-cost PC hardware, incorporates an Internet node, with access control, for depositing a minimal set of XML-based graphics files for presentation in an identical map format. Side-by-side viewing and televideo conferencing will permit rapid evaluation, data elaboration and recalculation (if necessary) and should produce strong consensus among decision makers. Successful completion affords easy utilisation by national/international organisations and non-nuclear states at risk of trans-boundary incursion.

Polar DOM was the most abundant DOM fraction, accounting for 56% of the isolated DOM. Colloidal organic matter was (super 14) C-age dated to be about 100% modern carbon and all of the DOM fractions were (super 14) C-age dated to be between 94 and 95% modern carbon. Average structural models of each DOM fraction were derived that incorporated quantitative elemental and infrared, (super 13) C-NMR, and electrospray/mass spectrometric data. The polar DOM model consisted of open-chain N-acetyl hydroxy carboxylic acids likely derived from N-acetyl heteropolysaccharides that constituted the colloidal organic matter. The less polar DOM fraction models consisted of aliphatic alicyclic ring structures substituted with carboxyl, hydroxyl, ether, ester, and methyl groups. These ring structures had characteristics similar to terpenoid precursors. All DOM fractions in the Great Salt Lake are derived from algae and bacteria that dominate DOM inputs in this lake.

Other natural boundary conditions included variable flow velocity and undersaturation of seawater with respect to the hydrate-forming species. Four cylindrical test specimens of pure, polycrystalline CH (sub 4) and CO (sub 2) hydrate were grown and fully compacted in the laboratory, then transferred by pressure vessel to the seafloor (1028 m depth), exposed to the deep ocean environment, and monitored for 27 hours using time-lapse and HDTV cameras. Video analysis showed diameter reductions at rates between 0.94 and 1.20 mu m/s and between 9.0 and 10.6.10 (super -2) mu m/s for the CO (sub 2) and CH (sub 4) hydrates, respectively, corresponding to dissolution rates of 4.15+ or -0.5 mmol CO (sub 2) /m (super 2) s and 0.37+ or -0.03 mmol CH (sub 4) /m (super 2) s. The ratio of the dissolution rates fits a diffusive boundary layer model that incorporates relative gas solubilities appropriate to the field site, which implies that the kinetics of the dissolution of both hydrates is diffusion-controlled. The observed dissolution of several mm (CH (sub 4) ) or tens of mm (CO (sub 2) ) of hydrate from the sample surfaces per day has major implications for estimating the longevity of natural gas hydrate outcrops as well as for the possible roles of CO (sub 2) hydrates in marine carbon sequestration strategies.

AN - 51716115; 2005-042784 AB - Some of the most valuable paleoclimate archives yet recovered are the multi-proxy records from the Greenland GISP2 and GRIP ice cores. The crucial importance of these data arises in part from the strong correlations that exist between the Greenland delta (super 18) O records and isotopic or other proxies in numerous other Northern Hemisphere paleoclimate sequences. These correlations could, in principle, allow layer-counted ice-core chronologies to be transferred to radiocarbondated paleoclimate archives, thus providing a (super 14) C calibration for the Last Glacial Maximum and Isotope Stage 3, back to the instrumental limits of the (super 14) C technique. However, this possibility is confounded by the existence of numerous different chronologies, as opposed to a single (or even a "best") ice-core time scale. This paper reviews how the various chronologies were developed, summarizes the differences between them, and examines ways in which further research may allow a (super 14) C calibration to be established.

Thus, it is desirable, when possible, to use calibration data obtained from secure dendrochronologically-dated wood from the corresponding hemisphere. In this paper, we outline the recent work and point the reader to the internationally recommended data set that should be used for future calibration of Southern Hemisphere (super 14) C dates.

The new data map (super 14) C variations ranging from the current limit of the tree-ring calibration (11,900 calendar years before present [cal BP], Kromer and Spurk 1998, now updated to 12,400 cal BP, see Kromer et al., this issue), to the (super 14) C-dating limit of 50,000 cal BP, with detailed structure between 14 to 16 cal kyr BP and 19 to 24 cal kyr BP. Samples older than 25,000 cal BP were analyzed with high-precision (super 231) Pa dating methods (Pickett et al. 1994; Edwards et al. 1997) as a rigorous second check on the accuracy of the (super 230) Th ages. These are the first coral calibration data to receive this additional check, adding confidence to the age data forming the older portion of the calibration. Our results, in general, show that the offset between calibrated and (super 14) C ages generally increases with age until about 28,000 cal BP, when the recorded (super 14) C age is nearly 6800 yr too young. The gap between ages before this time is less; at 50,000 cal BP, the recorded (super 14) C age is 4600 yr too young. Two major (super 14) C-age plateaus result from a 13 ppm drop in Delta (super 14) C between 14-15 cal kyr BP and a 700 ppm drop in Delta (super 14) C between 22-25 cal kyr BP. In addition, a large atmospheric Delta (super 14) C excursion to values over 1000 ppm occurs at 28 cal kyr BP. Between 20 and 10 cal kyr BP, a component of atmospheric Delta (super 14) C anti-correlates with Greenland ice Delta (super 18) O, indicating that some portion of the variability in atmospheric Delta (super 14) C is related to climate change, most likely through climate-related changes in the carbon cycle. Furthermore, the 28-kyr excursion occurs at about the time of significant climate shifts. Taken as a whole, our data indicate that in addition to a terrestrial magnetic field, factors related to climate change have affected the history of atmospheric (super 14) C.

Samples were collected at 3 European mountain sites at height levels of 1205 m (Schauinsland), 1800 m (Vermunt), and 3450 m asl (Jungfraujoch), and analyzed in the Heidelberg Radiocarbon Laboratory. The data set from Jungfraujoch (1986-2003) is considered to represent the free tropospheric background level at mid-latitudes of the Northern Hemisphere, as it compares well with recent (yet unpublished) measurements made at the marine baseline station Mace Head (west coast of Ireland). The Vermunt and Schauinsland records are significantly influenced by regional European fossil fuel CO (sub 2) emissions. The respective delta (super 14) CO (sub 2) depletions, on an annual mean basis, are, however, only 5 ppm less than at Jungfraujoch. Vermunt and Schauinsland both represent the mean continental European troposphere. JF - Radiocarbon AU - Levin, Ingeborg AU - Kromer, Bernd A2 - Reimer, Paula J.

Here, we present the revised Holocene oak chronology (HOC) and the Preboreal pine chronology (PPC) with respect to revisions, critical links, and extensions. Since 1998, the HOC has been strengthened by new trees starting at 10,429 BP (8480 BC). Oaks affected by cockchafer have been identified and discarded from the chronology. The formerly floating PPC has been cross-matched dendrochronologically to the absolutely dated oak chronology, which revealed a difference of only 8 yr to the published (super 14) C wiggle-match position used for IntCal98. The 2 parts of the PPC, which were linked tentatively at 11,250 BP, have been revised and strengthened by new trees, which enabled us to link both parts of the PPC dendrochronologically. Including the 8-yr shift of the oak-pine link, the older part of the PPC (pre-11,250 BP) needs to be shifted 70 yr to older ages with respect to the published data (Spurk 1998). The southern German part of the PPC now covers 2103 yr from 11,993-9891 BP (10,044-7942 BC). In addition, the PPC was extended significantly by new pine chronologies from other regions. A pine chronology from Avenches and Zurich, Switzerland, and another from the Younger Dryas forest of Cottbus, eastern Germany, could be crossdated and dendrochronologically matched to the PPC. The absolutely dated tree-ring chronology now extends back to 12,410 cal BP (10,461 BC). Therefore, the tree-ring based (super 14) C calibration now reaches back into the Central Younger Dryas. With respect to the Younger Dryas-Preboreal transition identified in the ring width of our pines at 11,590 BP, the absolute tree-ring chronology now covers the entire Holocene and 820 yr of the Younger Dryas.

These (super 14) C data for the summer season of each hemisphere were employed to construct zonal, hemispheric, and global data sets for use in regional and global carbon model calculations including calibrating and comparing carbon cycle models. In addition, extended monthly atmospheric (super 14) C data sets for 4 different zones were compiled for age calibration purposes. This is the first time these data sets were constructed to facilitate the dating of recent organic material using the bomb (super 14) C curves. The distribution of bomb (super 14) C reflects the major zones of atmospheric circulation. JF - Radiocarbon AU - Hua, Quan AU - Barbetti, Mike A2 - Reimer, Paula J.

As a result, no calibration curve for the time range 26-50 cal kyr BP can be recommended as yet, but in this paper the IntCal04 working group compares the available data sets and offers a discussion of the information that they hold.

The method takes account of uncertainty on both the (super 14) C and calendar scales, coherently integrating data, the calendar age estimates of which arise from different dating methods. It also allows for correlation between observations, if they have particular sources of uncertainty in common. We adopt an approach based on a random walk model, tailoring it to take account of possible calendar age offsets between different data sources by adding a random effect component. The latter allows us to use the same modeling framework for constructing the new calibration curve IntCal04, the comparison curve NotCal04, the Southern Hemisphere curve SHCal04, and the marine calibration curve Marine04.

Based on the strong rise of Delta (super 14) C at the onset of the Younger Dryas (YD) and wiggle-matching of the decadal-scale Delta (super 14) C fluctuations, we can anchor the floating chronology to the Cariaco varve chronology. We observe a marine reservoir correction higher than hitherto assumed for the Cariaco site, of up to 650 yr instead of 400 yr, for the full length of the comparison interval. The tree-ring Delta (super 14) C shows several strong fluctuations of short duration (a few decades) at 13,800, 13,600, and 13,350 cal BP. The amplitude of the strong Delta (super 14) C rise at the onset of the YD is about 40 ppm, whereas in the marine data set the signal appears stronger due to a re-adjustment of the marine mixed-layer Delta (super 14) C towards the atmospheric level.

The new calibration data set for terrestrial samples extends from 0-26 cal kyr BP, but with much higher resolution beyond 11.4 cal kyr BP than IntCal98. Dendrochronologically-dated tree-ring samples cover the period from 0-12.4 cal kyr BP. Beyond the end of the tree rings, data from marine records (corals and foraminifera) are converted to the atmospheric equivalent with a site-specific marine reservoir correction to provide terrestrial calibration from 12.4-26.0 cal kyr BP. A substantial enhancement relative to IntCal98 is the introduction of a coherent statistical approach based on a random walk model, which takes into account the uncertainty in both the calendar age and the (super 14) C age to calculate the underlying calibration curve (Buck and Blackwell, this issue). The tree-ring data sets, sources of uncertainty, and regional offsets are discussed here. The marine data sets and calibration curve for marine samples from the surface mixed layer (Marine04) are discussed in brief, but details are presented in Hughen et al. (this issue a). We do not make a recommendation for calibration beyond 26 cal kyr BP at this time; however, potential calibration data sets are compared in another paper (van der Plicht et al., this issue).

Several ways of reporting (super 14) C activity levels relative to a standard were also established, but no specific instructions were given for reporting nuclear weapons-testing (post-bomb) (super 14) C levels in samples. Because the use of post-bomb (super 14) C is becoming more prevalent in forensics, biology, and geosciences, a convention needs to be adopted. We advocate the use of fraction modern with a new symbol F (super 14) C to prevent confusion with the previously used Fm, which may or may not have been fractionation-corrected. We also discuss the calibration of post-bomb (super 14) C samples and the available data sets and compilations, but do not give a recommendation for a particular data set.

Background measurements are provided for the period when Cariaco samples were run, as well as revisions leading to the most recent version of the floating varve chronology. The floating Cariaco chronology has been anchored to an updated and expanded Preboreal pine tree-ring data set, with better estimates of uncertainty in the wiggle-match. Pending any further changes to the dendrochronology, these results represent the final Cariaco 58PC calibration data set.

The "flatness" of the calibration curve and the resultant wide range in calendrical dates provide little advantage over traditional archaeological dating in this period. Recent advances in Bayesian methodology have, however, created the possibility of refining and checking the established chronologies, based on typology of artifacts, against (super 14) C dates. The calibration process, within such a confined age range, however, relies heavily on the structural accuracy of the calibration curve.

Each process is directly linked to a corresponding trapping mechanism: immiscible plume migration to hydrodynamic trapping, plume-water interaction to solubility trapping, and plume-mineral interaction to mineral trapping. In this study, reactive transport modelling of CO (sub 2) storage in a shale-capped sandstone aquifer at Sleipner has elucidated and established key parametric dependencies of these fundamental processes, the associated trapping mechanisms, and sequestration partitioning among them during consecutive ten-year prograde (active-injection) and retrograde (post-injection) regimes. Intra-aquifer permeability structure controls the path of immiscible CO (sub 2) migration, thereby establishing the spatial framework of plume-aquifer interaction and the potential effectiveness of solubility and mineral trapping. Inter-bedded thin shales, which occur at Sleipner, retard vertical and promote lateral plume migration, thereby significantly expanding this framework and enhancing this potential. Actual efficacy of these trapping mechanisms is determined by compositional characteristics of the aquifer and caprock: the degree of solubility trapping decreases with increasing formation-water salinity, whereas that of mineral trapping is proportional to the bulk concentration of carbonate-forming elements, principally Fe, Mg, Ca, Na and Al. In the near-field environment of Sleipner-like settings, 80-85% by mass of injected CO (sub 2) remains and migrates as an immiscible fluid phase, 15-20% dissolves into formation waters, and less than 1% precipitates as carbonate minerals. This partitioning defines the relative effectiveness of hydrodynamic, solubility, and mineral trapping on a mass basis. Seemingly inconsequential, mineral trapping has enormous strategic significance: it maintains injectivity, delineates the storage volume, and improves caprock integrity. Four distinct mechanisms have been identified: dawsonite [NaAlCO (sub 3) (OH) (sub 2) ] cementation occurs throughout the intra-aquifer plume, while calcite-group carbonate [principally (Fe,Mg,Ca)CO (sub 3) ] precipitate via disparate processes along lateral and upper plume margins, and by yet another process within inter-bedded and caprock shales. The coupled mineral dissolution/precipitation reaction associated with each mechanism reduces local porosity and permeability. For Sleipner-like settings, the magnitude of such reduction for dawsonite cementation is near negligible; hence, this process effectively maintains initial CO (sub 2) injectivity. Of similarly small magnitude is the reduction associated with formation of carbonate rind along upper and lateral plume boundaries; these processes effectively delineate the CO (sub 2) storage volume, and for saline aquifers anomalously rich in Fe-Mg-Ca may partially self-seal the plume. Porosity and permeability reduction is most extreme within shales, because their clay-rich mineralogy defines bulk Fe-Mg concentrations much greater than those of saline aquifers. In the basal caprock shale of our models, these reductions amount to 4.5 and 13%, respectively, after the prograde regime. During the retrograde phase, residual saturation of immiscible CO (sub 2) maintains the prograde extent of solubility trapping while continuously enhancing that of mineral trapping. At the close of our 20-year simulations, initial porosity and permeability of the basal caprock shale have been reduced by 8 and 22%, respectively. Extrapolating to hypothetical complete consumption of Fe-Mg-bearing shale minerals (here 10 vol.% Mg-chlorite) yields an ultimate reduction of about 52 and 90%, respectively, after 130 years. Hence, the most crucial strategic impact of mineral trapping in Sleipner-like settings: it continuously improves hydrodynamic seal integrity of the caprock and, therefore, containment of the immiscible plume and solubility-trapped CO (sub 2) .

We analyzed MH sediments from West Olaf Lake (WOL) and Steel Lake (SL) in Minnesota to examine the effects of warm/dry climatic conditions on prairie-woodland ecosystems. Mineral composition and carbonate 18O were used to determine climatic variations, whereas pollen assemblages, charcoal 13C, and charcoal accumulation rates were used to reconstruct vegetation composition, C3 and C4 plant abundance, and fire. The ratio of aragonite/calcite at WOL and 18O at SL suggest that pronounced droughts occurred during the MH but that drought severity decreased with time. From charcoal 13C data we estimated that the MH abundance of C4 plants averaged 50% at WOL and 43% at SL. At WOL C4 abundance was negatively correlated with aragonite/calcite, suggesting that severe moisture deficits suppressed C4 plants in favor of weedy C3 plants (e.g., Ambrosia). As climate ameliorated C4 abundance increased (from 33 to 66%) at the expense of weedy species, enhancing fuel availability and fire occurrence. In contrast, farther east at SL where climate was cooler and wetter, C4 abundance showed no correlation with 18O-inferred aridity. Woody C3 plants (e.g., Quercus) were more abundant, biomass flammability was lower, and fires were less important at SL than at WOL. Our results suggest that C4 plants are adapted to warm/dry climatic conditions, but not to extreme droughts, and that the fire regime is controlled by biomass-climate interactions.

(1) Numerous hydrostatic and uniaxial compaction experiments on pure, gas-saturated porous hydrate indicate that effective pressures approaching 100 MPa are required to fully compact sI methane hydrate and sII methane-ethane hydrate. This compares with effective compaction pressures of less than 1 MPa for the compaction of granular ice near its melting temperature. (2) Hydrate/sand aggregates synthesized by the ice-to-hydrate method are found to be more cohesive and durable that comparable ice/sand aggregates. This observation is consistent with experience in drill coring of hydrate/sand intervals compared with that in permafrost. (3) Triaxial compression tests indicate that sI methane hydrate and sII methane-ethane hydrate have ductile flow strengths that are 20 to 100 times stronger than ice under the same conditions, suggesting that their effects in increasing the strength of sediments may be larger than the effect of ice formation in arctic soils in producing permafrost. These results suggest that hydrates may have similar roles as the diagenetic minerals quartz and carbonates during lithogenesis. Such strengthening effects of hydrates in sediments should be lost during thermal decomposition. This weakening effect of hydrate decomposition is in addition to the pore-pressure effect of gas release. Hydrate decomposition is endothermic and rate controlled by heat flow at temperatures above above 0 C. These properties place severe limits on the conditions under which decomposition may be thermally and mechanically unstable.

It is found that melting of Fe starts at 225 + or - 3 GPa (5 100 + or - 500 K) and is complete at 260 + or - 36 GPa (6100 + or - 500 K). No evidence was found for a previous report of a solid-solid phase transition on the Hugoniot curve near 200 GPa.

The data were interpreted manually and with a computer algorithm. The algorithm interpretation was adjusted to be consistent with atmospheric methane stratigraphic ties to the GISP2 (Greenland Ice Sheet Project 2) ice core, (super 10) Be stratigraphic ties to the dendrochronology (super 14) C record and the dated volcanic stratigraphy. The algorithm interpretation is more consistent and better quantified than the tedious and subjective manual interpretation.

By comparing apatite fission-track ages with cosmogenic data, erosion rates in southern Tibet appear to be decelerating since the Miocene, whereas in the Kunlun, erosion rates have accelerated over the same timescale. Such secular changes suggest that the southern and central regions of the plateau had formed their present flat relief by the Pleistocene. Unusually high erosion rates along the northern margin of the plateau may reflect intense tectonic activity during the Holocene. These findings indicate that over much of the high plateau erosion rates are exceptionally low, and therefore the sources of detritus carried by the great Asian rivers that rise in Tibet lie overwhelmingly in bedrocks at lower altitudes. This study illustrates the potential of cosmogenic studies for unraveling the most recent phase of the erosion/exhumation history of orogenic belts that cannot be resolved by either Ar-isotope or fission-track thermochronometers.

We show that summits in the Torngat and Kaumajet mountains were covered by ice during the Last Glacial Maximum, and that their felsenmeer cover probably survived multiple glaciation events. For similar lithologies, soils on felsenmeer covered summits are signigicantly more weathered than those below the felsenmeer limit, displaying higher concentrations of crystalline iron, amorphous aluminium, and silicium extracted with oxalate. Secondary minerals such as gibbsite and kaolinite occur in felsenmeer soils, whereas those formed in till lacked these secondary minerals. (super 10) Be and (super 26) Al exposure ages for nine of ten samples, from high-elevation tors and autochthonous felsenmeer blocks, range from 73+ or -6 to 157+ or -15 ka. By contrast, ages of 11.4+ or -1.0 and 11.7+ or -1.0 ka are measured for bedrock in the much lower Saglek zone, indicating extensive (>3 m) glacial erosion of this zone during Late Wisconsinan glaciation. (super 26) Al/ (super 10) Be ratios demonstrate that exposure of the high-elevation surfaces was interrupted during at least one cosmic ray shielding event by either ice or till cover. In either case, Late Wisconsinan glaciers could not have extensively eroded these surfaces. Five erratics dated above the Saglek zone, including one in the felsenmeer zone, have exposure ages ranging from 11.6+ or -1.0 to 13.6+ or -0.7 ka. This indicates that valley and high-elevation ice persisted through the Younger Dryas Chron and provides further evidence that the highlands were not nunataks during the Late Wisconsinan period.

The specimen was collected from a drill core on the Huon Peninsula and has been independently dated with (super 230) Th. A site-specific reservoir correction has been applied to the results, and coral growth bands were used to calibrate individual growth years. Alternating density bands, which are the result of seasonal growth variations, were subsampled to provide 2 integrated 6-month (super 14) C measurements per year. This allows for 20 independent measurements to be averaged for each decadal value of the (super 14) C calibration, making these results the highest resolution data set available for this brief time range. The finestructure of the data set exhibits (super 14) C oscillations with frequencies on the order of 4 to 10 yr, similar to those observed in modern coral (super 14) C records.

The latter record was first published by Bard et al. (2004a,b), with the subsequent addition of some data by Shackleton et al. (2004). These data sets are compared with the IntCal98 record (Stuiver et al. 1998) and with data sets based on other archives, such as varves of Lake Suigetsu (Kitagawa and van der Plicht 1998, 2000), speleothems from the Bahamas (Beck et al. 2001), and Cariaco sediments (Hughen et al. 2004). Up to 26,000 cal BP, the Iberian Margin data agree within the errors of the other records. By contrast, in the interval between 33,000 and 41,000 cal BP, the Iberian Margin record runs between the Lake Suigetsu and Bahamian speleothem data sets, but it agrees with the few IntCal98 coral data and the Cariaco record.

The new calibration data sets extend an additional 2000 yr, from 0-26 cal kyr BP (Before Present, 0 cal BP = AD 1950), and provide much higher resolution, greater precision, and more detailed structure than IntCal98. For the Marine04 curve, dendrochronologically-dated tree-ring samples, converted with a box diffusion model to marine mixed-layer ages, cover the period from 0-10.5 cal kyr BP. Beyond 10.5 cal kyr BP, high-resolution marine data become available from foraminifera in varved sediments and U/Th-dated corals. The marine records are corrected with site-specific (super 14) C reservoir age information to provide a single global marine mixed-layer calibration from 10.5-26.0 cal kyr BP. A substantial enhancement relative to IntCal98 is the introduction of a random walk model, which takes into account the uncertainty in both the calendar age and the (super 14) C age to calculate the underlying calibration curve (Buck and Blackwell, this issue). The marine data sets and calibration curve for marine samples from the surface mixed layer (Marine04) are discussed here. The tree-ring data sets, sources of uncertainty, and regional offsets are presented in detail in a companion paper by Reimer et al. (this issue).

In this power plant, methane is combusted with oxygen in a gas generator to produce the working fluid for the turbines. The combustion produces a gas mixture composed of steam and carbon dioxide. These gases drive multiple turbines to produce electricity. The turbine discharge gases pass to a condenser where water is captured. A stream of pure carbon dioxide then results that can be used for enhanced oil recovery or for sequestration. The analysis considers a complete power plant layout, including an air separation unit, compressors and intercoolers for oxygen and methane compression, a gas generator, three steam turbines, a reheater, two preheaters, a condenser, and a pumping system to pump the carbon dioxide to the pressure required for sequestration. This analysis is based on a 400 MW electric power generating plant that uses turbines that are currently under development by a U.S. turbine manufacturer. The high-pressure turbine operates at a temperature of 1089 K (1500DGF) with uncooled blades, the intermediate-pressure turbine operates at 1478 K (2200DGF) with cooled blades and the low-pressure turbine operates at 998 K (1336DGF). The power plant has a net thermal efficiency of 46.5%. This efficiency is based on the lower heating value of methane, and includes the energy necessary for air separation and for carbon dioxide separation and sequestration.

To do this, the organism must invade and survive within both epithelial and endothelial cells. We have identified a facilitator of NTHi survival inside human cells, virulence-associated protein D (vapD sub(Hi), encoded by gene HI0450). Both vapD sub(Hi) and a flanking gene, HI0451, exhibit the genetic and physical characteristics of a toxin/antitoxin (TA) locus, with VapD sub(Hi) serving as the toxin moiety and HI0451 as the antitoxin. We propose the name VapX sub(Hi) for the HI0451 antitoxin protein. Originally identified on plasmids, TA loci have been found on the chromosomes of a number of bacterial pathogens, and have been implicated in the control of translation during stressful conditions. Translation arrest would enhance survival within human cells and facilitate persistent or chronic mucosal infections. Isogenic mutants in vapD sub(Hi) were attenuated for survival inside human respiratory epithelial cells (NCI-H292) and human brain microvascular endothelial cells (HBMEC), the in vitro models of mucosal infection and the blood-brain barrier, respectively. Transcomplementation with a vapD sub(Hi) allele restored wild-type NTHi survival within both cell lines. A PCR survey of 59 H. influenzae strains isolated from various anatomical sites determined the presence of a vapD sub(Hi) allele in 100% of strains. Two isoforms of the gene were identified in this population; one that was 91 residues in length, and another that was truncated to 45 amino acids due to an in-frame deletion. The truncated allele failed to transcomplement the NTHi vapD sub(Hi) survival defect in HBMEC. Subunits of full-length VapD sub(Hi) homodimerized, but subunits of the truncated protein did not. However, truncated protein subunits did interact with full-length subunits, and this interaction resulted in a dominant-negative phenotype. Although Escherichia coli does not contain a homologue of either vapD sub(Hi) or vapX sub(Hi), overexpression of the VapD sub(Hi) toxin in trans resulted in E. coli cell growth arrest. This arrest could be rescued by providing the VapX sub(Hi) antitoxin on a compatible plasmid. We conclude that vapD sub(Hi) and vapX sub(Hi) may constitute a H. influenzae TA locus that functions to enhance NTHi survival within human epithelial and endothelial cells.

Gene network models are needed to interpret the resulting large and complex data sets. Rationally designed perturbations (e.g., gene knock-outs) can be used to iteratively refine hypothetical models, suggesting an approach for high-throughput biological system analysis. We introduce an approach to gene network modeling based on a scalable linear variant of fuzzy logic: a framework with greater resolution than Boolean logic models, but which, while still semi-quantitative, does not require the precise parameter measurement needed for chemical kinetics-based modeling. Results: We demonstrated our approach with exhaustive search for fuzzy gene interaction models that best fit transcription measurements by microarray of twelve selected genes regulating the yeast cell cycle. Applying an efficient, universally applicable data normalization and fuzzification scheme, the search converged to a small number of models that individually predict experimental data within an error tolerance. Because only gene transcription levels are used to develop the models, they include both direct and indirect regulation of genes. Conclusions: Biological relationships in the best-fitting fuzzy gene network models successfully recover direct and indirect interactions predicted from previous knowledge to result in transcriptional correlation. Fuzzy models fit on one yeast cell cycle data set robustly predict another experimental data set for the same system. Linear fuzzy gene networks and exhaustive rule search are the first steps towards a framework for an integrated modeling and experiment approach to high-throughput "reverse engineering" of complex biological systems.

The test was carried out under conditions simulating those expected during actual remediation of a single shell tank located at the U. S. Department of Energy Hanford Reservation, Washington. A system was developed for the experiment to allow remote operation during the entire test. Approximately 54,000 liters of concentrated sodium thiosulfate (simulating tank waste) were episodically released from a steel tank in a blind test lasting 110 days (no knowledge of the release episodes during the course of the test were provided). ERT data were collected using an array of point electrodes installed in boreholes around the tank. Each day during the test a leak or no-leak condition was declared based solely on analysis of the electrical data. The success rate of the declarations made during the test was only 57%, however, further analysis carried out at the end of the test resulted in a significant improvement of the success rate. The results suggest that ERT, used either with custom built electrode arrays or existing steel cased wells, can provide an effective means of monitoring remediation or long-term integrity of underground storage tanks.

AN - 71453325; 14642568 AB - Xrcc1 knockout embryos show increased DNA breakage and apoptosis in tissues of the embryo proper prior to death at embryonic day E6.5. An additional deficiency in Trp53 allows Xrcc1(-/-) embryos to enlarge slightly and initiate gastrulation although ultimately death is delayed by less than 24h. Death presumably results from DNA damage that reaches toxic levels in the post-implantation mouse embryo. To investigate the level of XRCC1 protein needed for successful mouse development, we derived Xrcc1 transgene-complemented Xrcc1(-/-) mice that express Xrcc1 within the normal range or at a greatly reduced level (<10% normal). The greatly reduced XRCC1 protein level destabilized the XRCC1 partner protein DNA ligase III (LIG3) but still allowed for successful mouse development and healthy, fertile adults. Fibroblasts from these animals exhibited almost normal alkylation sensitivity measured by differential cytotoxicity. Thus, a large reduction of both XRCC1 and DNA ligase III has no observable effect on mouse embryogenesis and post-natal development, and no significant effect on cellular sensitivity to DNA alkylation.

AN - 71511927; 14710934 AB - The sorption of uranium on to Ordinary Portland Cement (OPC)/Pulverized Fuel Ash (PFA, fly ash) grout material has been investigated with respect to time, pH, grout:uranium ratio and the chemical composition of the supporting solution. The information obtained is of relevance to the disposal of low-level nuclear waste. The grout material has been chemically characterised and is negatively charged above pH 2.3. At the uranium concentrations studied (2 microM) all uranyl hydroxide aqueous species are expected to be monomeric, rather than polymeric. Uranium(VI) sorption on to the grout material has been explained in terms of inner sphere complexation binding by means of hydroxide bridge formation between the uranium and grout surface. It is also proposed that oligomeric uranyl species are formed across the grout surface, perhaps stabilising the repulsive effects of the negatively charged grout surface and anionic uranyl hydroxide species.

The purpose of this study is to determine the origin and history of waters associated with the formation, using long-lived cosmogenic and stable isotope systems. Ratios of (super 129) I/I and stable isotope values (delta D and delta (super 18) O) were determined in waters from close to 100 wells, (super 36) Cl/Cl ratios for a subset of these samples. A significant group of samples has (super 129) I/I ratios between 100X10 (super -15) and 200X10 (super -15) , indicating minimum iodine ages close to 60 Ma. If these ages are corrected for the addition of fissiogenic (super 129) I, they are compatible with the depositional age of the Fruitland Formation (Late Cretaceous). Several sets of waters are clearly present within the data. A group dominated by infiltration of recent surface waters is restricted to the uplifted basin margins, with a lateral extent of less than 5 km from outcrop, and is characterized by (super 129) I/I ratios in excess of 1500X10 (super -15) and meteoric delta D, delta (super 18) O, and (super 36) Cl/Cl signatures. The rest of the basin is characterized by several subsets of formation waters which have undergone variable degrees of iodine enrichment through diagenesis as well as variable degrees of dilution. The first subgroup is found in coals of relatively low vitrinite reflectance and moderate enrichment of iodine. This subgroup predominantly consists of entrapped pore fluids, although it may also contain waters which infiltrated the coals at the time of the Laramide uplift, between 25 and 30 Ma. A second subgroup consists of formation waters associated with coals of high vitrinite reflectance. Despite subsequent uplift, the high iodine concentrations and low (super 129) I/I ratios of this subgroup, as well as a moderate depletion of deuterium relative to (super 18) O, suggest that these waters were not significantly altered since the time when diagenetic reactions occurred in the deepest portion of the basin. A third subgroup, with higher delta D and delta (super 18) O values as well as higher (super 129) I/I ratios, extends roughly west to east at the New Mexico-Colorado state line and corresponds to a region of extensive fracturing of the coalbeds. In this case, the higher (super 129) I/I ratios are probably due to contributions of fissiogenic (super 129) I through fracture flow, perhaps from deeper formation waters. Our results do not support models of subsequent basin-wide groundwater migration in the Fruitland Formation. The combined use of (super 129) I and (super 36) Cl with stable isotope studies provides valuable information as to the hydrologic history of coalbed methane deposits, as well as their potential for commercial exploitation.

Recently, permanent electrode arrays have been installed at a number of sites as a means of long term monitoring of the integrity of a landfill liner. There has, however, been no scientific study to date which addresses the performance of such systems. Here, we utilise a physical scale model of a landfill liner/cap and investigate the usefulness of grid based and boundary electrode arrays for detecting multiple leaks in a landfill liner or cap. We compare the two electrode geometries under a series of controlled electrical leak experiments and demonstrate how both these arrangements can detect and locate leaks in a geomembrane. We also demonstrate some of the limitations of the method. For example, present data processing schemes can give misleading results when there are multiple leaks. The influence of variation in resistivity of the soil above or below the liner and also boundary current leakage on the performance of the technique is also studied. The results suggest that these two factors, unless they are accounted for, can have a significant impact on the results and subsequently affect the practical value of electrical leak detection systems.

The experimental results indicate a strong dependence of the effective Cs super(+) K sub(d) on the concentrations of other cations, including Na super(+) that is present at high to extremely high concentrations in fluids leaking from the Hanford SX tanks. A strong dependence of the Cs super(+) K sub(d) on the aqueous Cs super(+) concentration is also apparent, with retardation of Cs super(+) increasing from a value of 41 at a Cs super(+) concentration of 10 super(-4) M in the feed solution to as much as 282 at a Cs super(+) concentration of 5x10 super(-7) M, all in a background of 1 M NaNO sub(3). The total cation exchange capacity (CEC) of the Hanford sediment was determined using super(22)Na isotopic equilibrium exchange in a flow-through column experiment. The value for the CEC of 120 mu eq/g determined with this method is compatible with a value of 121.9 mu eq/g determined by multi-cation elution. While two distinct exchange sites were proposed by Zachara et al. [Geochim. Cosmochim. Acta 66 (2002) 193] based on binary batch exchange experiments, a third site is proposed in this study to improve the fit of the Cs super(+)-Na super(+) and Cs super(+)-Ca super(+) exchange data and to capture self-sharpened Cs super(+) breakthrough curves at low concentrations of Cs super(+). Two of the proposed exchange sites represent frayed edge sites (FES) on weathered micas and constitute 0.02% and 0.22% of the total CEC. Both of the FES show a very strong selectivity for Cs super(+) over Na super(+) (K sub(Na-Cs)=10 super(7.22) and 10 super(4.93), respectively). The third site, accounting for over 99% of the total CEC, is associated with planar sites on expansible clays and shows a smaller Na super(+)- Cs super(+) selectivity coefficient of 10 super(1.99). Parameters derived from a fit of binary batch experiments alone tend to under predict Cs super(+) retardation in the column experiments. The transport experiments indicate 72-90% of the Cs super(+) sorbed in experiments targeting exchange on FES was desorbed over a 10- and 24- day period, respectively. At high Cs super(+) concentrations, where sorption is controlled primarily by exchange on planar sites, 95% of the Cs super(+) desorption was desorbed. Most of the difficulty in desorbing Cs super(+) from FES is a result of the extremely high selectivity of these sites for Cs super(+), although truly irreversible sorption as high as 23% was suggested in one experiment. The conclusion that Cs super(+) exchange is largely reversible in a thermodynamic sense is supported by the ability to match Cs super(+) desorption curves almost quantitatively with an equilibrium reactive transport simulation. The model for Cs super(+) retardation developed here qualitatively explains the behavior of Cs super(+) in the Hanford vadose zone underneath a variety of leaking tanks with differing salt concentrations. The high selectivity of FES for Cs super(+) implies that future desorption and migration is very unlikely to occur under natural recharge conditions.

The amounts of MeIQx, DiMeIQx, IFP, and PhIP in the liquid portion of the digestate were compared to levels in the undigested meat to determine the percentage released (accessible fraction). Incubating the meat with amylase and pepsin did not change the accessibility of HAs when compared to incubation with water alone. In contrast, increasing amounts of pancreatin increased the accessibility up to 6.4-fold. Comparing the amounts of the HAs in the liquid to the solid fraction showed that there was more MeIQx, DiMeIQx, and IFP in the liquid fraction. In contrast, PhIP was equally divided between the solid and liquid fractions. For all four compounds, increasing the doneness of the meat decreased the amount of the compound accessible from the meat matrix. Our data suggest that bioaccessability of HAs may vary according to the polarity of the individual HAs and also may depend upon the doneness of the meat. These results may have important ramifications for human feeding studies, which assume that the total amount of each HA in the meat matrix is equally bioavailable.

From 1953 to 1999 delta super(13)C decreased by 0.9ppt. Pre-bomb delta super(14)C is-59ppt, consistent with coral based estimates from the same region and the post-bomb maximum (+121ppt) is achieved in 1973. A 1-D box-diffusion model was employed to quantify vertical diffusivity and air- sea exchange rates. The model suggests that a low vertical diffusion rate (0.1 cm super(2) s super(-1)) coupled with a moderate CO sub(2) exchange rate produces the overall observed shape of the pre-post bomb delta super(14)C record and the general large scale features of the delta super(13)C time series.

AN - 71332087; 14596589 AB - Amyloid beta 1-42 (Abeta(1-42)) is a self-associating peptide that becomes neurotoxic upon aggregation. Toxicity originally was attributed to the presence of large, readily formed Abeta fibrils, but a variety of other toxic species are now known. The current study shows that Abeta(1-42) can self-assemble into small, stable globular assemblies free of fibrils and protofibrils. Absence of large molecules was verified by atomic force microscopy (AFM) and nondenaturing gel electrophoresis. Denaturing electrophoresis revealed that the globular assemblies comprised oligomers ranging from trimers to 24mers. Oligomers prepared at 4 degrees C stayed fibril-free for days and remained so when shifted to 37 degrees C, although the spectrum of sizes shifted toward larger oligomers at the higher temperature. The soluble, globular Abeta(1-42) oligomers were toxic to PC12 cells, impairing reduction of MTT and interfering with ERK and Rac signal transduction. Occasionally, oligomers were neither toxic nor recognized by toxicity-neutralizing antibodies, suggesting that oligomers could assume alternative conformations. Tests for oligomerization-blocking activity were carried out by dot-blot immunoassays and showed that neuroprotective extracts of Ginkgo biloba could inhibit oligomer formation at very low doses. The observed neurotoxicity, structure, and stability of synthetic Abeta(1-42) globular assemblies support the hypothesis that Abeta(1-42) oligomers play a role in triggering nerve cell dysfunction and death in Alzheimer's disease.

We compare the climatic response to increased greenhouse gases of the National Center for Atmospheric Research (NCAR) climate model, CCM3, at T42 and T170 resolutions (horizontal grid spacing of 300 and 75km respectively). All simulations use prescribed sea surface temperatures (SST). Simulations of the climate of 2100 ad use SSTs based on those from NCAR coupled model, Climate System Model (CSM). We find that the global climate sensitivity and large-scale patterns of climate change are similar at T42 and T170. However, there are important regional scale differences that arise due to better representation of topography and other factors at high resolution. Caution should be exercised in interpreting specific features in our results both because we have performed climate simulations using a single atmospheric general circulation model and because we used with prescribed sea surface temperatures rather than interactive ocean and sea-ice models.

Cosmogenic radionuclide and optically stimulated luminescence dating indicates that two glacial advances occurred in marine isotope stage (MIS)-3 and MIS-2. In the Anyemaqen Mountains, a third advance occurred in the Early Holocene. We suggest that glaciation was synchronous in the Anyemaqen and Nianbaoyeze Mountains, as well as in other glaciated areas of Tibet and the Himalaya that are influenced by the Asian monsoon. The maximum extent of glaciation occurred early in the last glacial cycle (MIS-3) during a time of increased insolation when the monsoon intensified and supplied abundant precipitation, as snow at high altitude, to feed high-altitude glaciers. This suggests that precipitation, as snow, is fundamental in controlling glaciation in these regions. However, the occurrence of glacial advances during the insolation minimum of MIS-2 suggests that, despite reduced precipitation at this time, the annual temperatures were cold enough to maintain positive glacier mass balances. The numerically defined chronologies for the Anyemaqen and Nianbaoyeze Mountains presented here provide a framework for comparing glacial advances in other parts of high Asia.

The results indicate rapid alluvial transport with minimal alluvial storage and suggest that most of the cosmogenic nuclide inventory in sediments is accumulated while they are eroding from bedrock and travelling down hill slopes. Spatially homogeneous erosion rates of 25- 30 mm/ka are calculated throughout the Great Smoky Mts. It is concluded that rates of erosion for the Appalachians integrated over varying time periods from decades to 100 Ma are similar, the result of equilibrium between erosion and isostatic uplift in the region.

Glaciation in this region is controlled by two major climatic systems: the mid-latitude westerlies and the South Asian monsoon. In addition, significant interannual climatic variability in the region is associated with El Nino-Southern Oscillation. Furthermore, glaciation is strongly influenced by topographic constraints. The glacial system provides water for hundreds of millions of people in central Asia, and variations in the glacial and associated hydrological systems have profound socio-economic and political consequences. Yet despite the regional and global importance of glaciation in High Asia, the dynamics, extent and timing of Late Quaternary glaciation in this region are poorly understood and defined. This is particularly so for the last glacial-interglacial transition. To examine the nature of glacier oscillations, key areas throughout the Himalaya and Tibet were studied using glacial geomorphic mapping, sedimentology, and cosmogenic radionuclide (CRN) surface exposure and optically stimulated luminescence (OSL) dating techniques to define the timing and extent of Late Quaternary glaciation. These studies show a strong monsoonal influence on glaciation, synchroneity of glaciation throughout the region and strong topographic constraints on extent of glaciation. Furthermore, it is evident that glaciation was restricted in extent during the global Last Glacial Maximum (LGM), contrasting with extensive advances during insolation maximum in early part of the last glacial cycle. Nevertheless, notable glacial advances occurred during latter part of the LGM ( approximately 15-16 ka), the Lateglacial Interstadial, and the early Holocene. These glacial advances were most extensive in the monsoon-influenced regions and may have even been more extensive than the LGM advance. The results suggest that glaciation throughout Tibet and the Himalaya is controlled by precipitation changes related to oscillations in the southwest Asian monsoonal system combined with cooling that is broadly coincident with the global cooling cycles.

A published kinematic model for the Eastern California Shear Zone suggests that 1.4-4.1 mm/yr of Owens Valley fault slip continues northward along the White Mountains fault zone. New geologic mapping, geomorphic, and geochronologic investigations along the White Mountains fault zone shed light on its Quaternary dextral fault slip history and allow us to test this kinematic model. Drainages, shutter ridges, and ridgelines show dextral offsets that range from approximately 5 to 559+ or -7 meters. Beryllium-10 cosmogenic radionuclide dating methods used on in situ boulders demonstrate that the age of the oldest fan surface is 225+ or -25 ka. Minimum offset of drainages developed within the oldest fan surface is 559+ or -7 meters, yielding a minimum late Pleistocene slip rate of 2.5+ or -0.3 mm/yr. Our new data refine a kinematic model proposed for the recent evolution of dextral fault slip in the Eastern California Shear Zone.

Sample sites are at an altitude of 2100 to 2300 m. Stable isotope analyses are used to assess the contribution of cool and warm season precipitation to the recharge budget, and to evaluate the timing and extent of evaporation during recharge. Cool season precipitation (mostly snowfall) accounts for 75 to 80% of the annual precipitation total, and has an average deuterium value that is 40 to 70 permil lighter than average summer rainfall. Perched mountain springs located near each precipitation gauge show small isotopic variations over time (generally less than 5 permil), and are reasonable proxies for average local recharge. Comparison of the stable isotope data for precipitation and springs suggests more than 90% of recharge originates from cool season precipitation. Three of the four springs show isotopic evidence of moderate evaporation, inferred to occur during recharge. Shallow soil infiltration samples collected in lysimeters show variations in infiltration amount from year-to-year, independent of the total precipitation amount. The rate at which the snowpack melts may be a key control on the net infiltration flux. Smaller net infiltration volumes tend to show large evaporation effects whereas larger volumes show little evidence of significant evaporation. Water vapor loss through the soil zone during slow infiltration is inferred to be the dominant control on evaporation during recharge.

Cosmogenic dating ( (super 10) Be and (super 26) Al) of boulders on moraines in valleys bordering the Junin Plain in the central Peruvian Andes (ca. 11 degrees S, 76 degrees W, altitude 4100 m) and in the Cordillera Real of the Bolivian Andes (ca. 16 degrees 16'S, 68 degrees 9'W, altitude 4600 m) indicates that the local last glacial maximum likely occurred during oxygen isotope stage 2, but prior to the inferred peak of Northern Hemisphere continental glaciation (approximately 21,000 calendar years BP). The moraines deposited by older glaciations in the study areas are substantially larger and extend farther downvalley than those of the local last glacial maximum. We have been studying snowline depression at the last glacial maximum in tropical South America. Modern snowline in the region has been estimated from remaining small ice caps and geomorphic evidence at approximately 4800-5000 m. Valleys in the study area bordering the Junin Plain are relatively shallow, having a maximum difference in altitude between headwall and mouth of about 700 m (Alcacocha Valley). This shallow profile constrains snowline depression. Our estimate of the snowline at the local last glacial maximum in Alcacocha Valley is approximately 4600 m, indicating a relatively small snowline depression of about 200-400 m. Estimates of snowline at the last glacial maximum elsewhere in tropical South America range from about 300 m to more than 1000 m, but the related deposits typically have not been dated directly. Few, if any, moraines in tropical South America have been tightly constrained in age to the last glacial maximum of the Northern Hemisphere, or even to a local last glacial maximum. Our results, which include direct dating of moraines from the local last glacial maximum and from previous glaciations, make a fundamental contribution to paleoclimate reconstruction efforts in the tropics.

Disequilibrium in this ratio in a sample implies a complex history of exposure and burial. Measurement of Be-10 and Al-26 in quartz from bedrock surfaces throughout the Ford Ranges, West Antarctica, reveals a history of exposure, burial beneath the West Antarctic Ice Sheet, and survival against sub-glacial erosion. Except for low-altitude surfaces heavily scoured by the ice sheet, all surfaces display disequilibrium in the ratio of Al-26 to Be-10 and have apparent exposure ages significantly older than Holocene deglaciation. The data show that: (1) Effective exposure time increases with altitude on each mountain, (2) The ratio of time-exposed to time covered by ice decreases with altitude on each mountain and roughly decreases inland, (3) Minimum overall burial times range from hundreds of thousands to approximately 3.5 million years, and (4) Maximum limits on the fraction of time-exposed (compared to the time covered by ice) for these samples are as low as 1-5%. These results are consistent with survival of the surfaces through repeated Plio-Pleistocene glaciations, and indicate that the present deglaciation of West Antarctica is among the most extensive in the mid- to late-Quaternary. Bedrock in the Ford Ranges is variably weathered, from clean, glacially abraded surfaces at low altitude, to weathered surfaces at high altitude, showing surficial oxidation, salt and gruss accumulation, widened joints and rounded corners. Our data show that weathered features at high altitude are the result of repeated exposure and glaciation, rather than continuous sub-aerial weathering.

However, interpretations of bulk fluid-calcite experiments in the literature disagree upon the most fundamental assumptions regarding the influences of temperature, growth rate, impurity concentration, and salinity on Mg uptake. To begin addressing this problem, we conducted a new type of calcite growth study: while temperature and solution chemistry were precisely controlled, we directly quantified near-equilibrium, layer-mechanism growth rates and Mg contents of calcite crystals. We measured migration rates of monomolecular steps in situ on individual growth spirals on {104} calcite faces using atomic force microscopy. Solutions containing CaCl (sub 2) , NaHCO (sub 3) , MgCl (sub 2) , and 0.1 molal NaCl flowed continuously over samples. Growth rates were determined at 15-30 degrees C in solutions containing 0-10 (super -4) molal [Mg] and with supersaturations (ln [(aCa++XaCO3--)/Ksp]) of 0.3-1.0. In complementary experiments, we grew seed crystals under identical conditions for several days to produce large growth hillocks for high-resolution electron microprobe analysis. We find that Mg exhibits a pronounced, non-uniform partitioning into growth hillocks with a distinct preference for geometrically obtuse steps ( approximately 100 to >3000 ppm) over acute steps (0 to approximately 800 ppm). This partitioning is opposite to results of Paquette and Reeder (1995; GCA 59:735) for calcite grown at high ionic strength (1-2 molal) with multiple impurities in solution. Our work suggests that the interaction of Mg with calcite surfaces depends upon nanoscale site geometry and also upon the presence or absence of other trace elements. Preliminary findings suggest that of the factors named above, supersaturation has the strongest influence on Mg/Ca in the solid crystals. Our work on inorganic controls of impurity partitioning in calcite sets the stage for investigation of biological effects and for robust interpretation of trace element signatures in biogenic calcite.

Previous studies show that the form and chemistry of biogenic carbonates are affected by factors such as temperature, salinity, water turbidity and dissolved oxygen. To complicate these relationships, complex biological processes, termed "vital effects", also influence the compositions of skeletal materials during mineral formation. Quantifying molecular-scale controls on mineralization in the absence of "vital effects" is essential to sorting out the principles that control compositional signatures of biogenic carbonates. Here we use in situ atomic force microscopy to observe directly the molecular scale effects of Sr on layer growth of abiotic calcite and couple these insights with quantitative measurements of the kinetics and thermodynamics of growth. Strontium inhibits calcite growth by different mechanisms for positive (larger, geometrically more open kink sites) and negative (smaller and more shielded kink sites) surface coordination environments that characterize calcite step edge directions. Low concentrations of strontium enhance the rate of calcite growth through changes in kinetics. A new conceptual model is introduced to explain this behavior. Higher concentrations of strontium inhibit and ultimately stop calcite growth by a step blocking mechanism. The critical supersaturation required to initiate growth increases with increasing levels of strontium. At higher supersaturations, strontium causes growth rates to increase to levels greater than those for the pure system. The step blocking model proposed by Cabrera and Vermilyea (1958) does not predict this experimental behavior. Preliminary evidence indicates that strontium is preferentially incorporated into the positive step directions, and impurity concentrations are not homogeneous throughout the structure. This study demonstrates that strontium and magnesium have different surface interaction mechanisms, showing the importance of understanding growth processes at the nanoscale. We reiterate the significance of interpreting impurity signatures within the framework of step-specific interactions that occur during mineralization.

Less data are available regarding changes in longer, decadal-scale climate cycles through the Holocene. We present sedimentologic, geochemical, and image analysis data from annually laminated Derby Lake, Michigan (43 degrees 16'15"N lat., 85 degrees 7'30"W lon.) suggesting similar changes in decadal-scale variability occurred during the Mid-Holocene. Decadal-scale cycles are expressed in Derby Lake sediment as changes in the carbonate content, with carbonate alternating between high values (40-80%) and low values (<10%) for periods of a few years to multiple decades. Transitions between carbonate-rich and carbonate-depleted sediments are typically abrupt, occurring within 1 to 10 varve years, and form visually striking cm-scale bundles of light carbonate-rich laminations and dark carbonate-depleted laminations. These cycles are documented visually, as well as quantified in sediment grayscale intensity, carbon coulometry, and stable isotope data. Beginning in the early Holocene (8400 cal yr BP), Derby Lake varves were dominantly carbonate rich, with some carbonate depletion events occurring around 8200 cal yr BP. A period of low lake level followed, and Mid-Holocene Derby Lake sediments are dominated by elevated carbonate abundance, and a paucity of carbonate depletion events. Beginning gradually after 5300 cal yr BP, carbonate depletion events recur and continue to increase in frequency and intensity until 1500 cal yr BP, where cycles begin to taper off, with a final carbonate-depletion cycle ending in the Little Ice Age. We suggest that carbonate-depletion cycles are environmentally driven phenomena reflecting changes in decadal-scale climatic variability in Michigan through the Holocene. Links to the Pacific ocean-atmosphere system are suspected drivers in these changes, and the phenomena may also be linked to similar changes observed in the ENSO system during these times.

The older Mattole terraces have higher proportions of unsaturated alkyl and aromatic carbon groups than the more recently formed terraces. Precipitation at Mattole is nearly double that at Santa Cruz which results in increased weathering of parent material. Our NMR results suggest that weathering patterns shape the specific types of carbon stored within the soil mineral matrix.

The majority of water samples are very dilute and are predominantly steam that condensed in the sampling lines. A few samples with up to approximately 80 ppm Cl may contain rock-pore fluids. Suites of water samples with distinctive compositions were collected from packed-off intervals in two boreholes. These generally low-pH samples contained large amounts of Cl (up to 1,250 ppm) and SO (sub 4) (up to 821 ppm), plus detectable Cr, Mn, Ni, and Zn. The neoprene (polychloroprene) packers were considered possible sources of fluid modification, because they contain both Cl and S. Steel components of the packers are possible sources of the transition metals. Two types of heating tests were performed on neoprene and tuff samples. In the flow-through test, air was circulated through test cells with ground samples of neoprene or tuff or through an empty test cell at 190, 130, and 90 degrees C. The air was then bubbled through water to extract soluble volatile species. Water samples associated with neoprene contained elevated chloride (up to 18,791 ppm) and sulfate (up to 155 ppm) and had lower pH than samples from the other test cells. More acidic and higher chloride samples were collected from neoprene at higher temperature. In follow-up tests at lower temperatures, detectable lowering of pH due to neoprene degradation was noted at temperatures as low as 59 degrees C, with a pronounced pH effect at 71 degrees C. Boiling-water tests contacted tuff or neoprene directly with boiling water for eight days. The pH of water with tuff was buffered by tuff-gas reactions. For water with neoprene, the pH was not strongly affected, yet chloride (up to 339 ppm) and sulfate (up to 55 ppm) were produced. In the flow-through test, oxygen was readily available, resulting in the generation of HCl from the oxidized neoprene. In the boiling test, the oxygen concentration was insufficient for much oxidation of neoprene to occur. The tests show that generation of Cl-rich low pH waters may occur in borehole intervals at sub-boiling and near-boiling temperatures with temperature gradients within the packed intervals.

Ratios greater than 1,250X10 (super -15) were previously reported from the northern Exploratory Studies Facility (ESF) tunnel and were interpreted to have a bomb-pulse source indicating percolation to depths of 200 to 300 m below land surface in the last 50 years. In contrast, samples from the southern ESF had (super 36) Cl/Cl ratios near the Holocene meteoric value of 500X10 (super -15) , despite generally similar hydrogeologic conditions. Attempts to reproduce high ratios yielded mixed results. To resolve the issue, the U.S. Department of Energy requested an independent validation study (VS), organized by the U.S. Geological Survey, to corroborate the presence of bomb-pulse (super 36) Cl/Cl ratios. The VS used core primarily from 4-m-long boreholes drilled across a fractured zone where 11 of 18 ESF tunnel-wall samples and 8 of 10 core samples were previously reported to have bomb-pulse (super 36) Cl/Cl ratios. New VS samples were crushed and sieved between 2- and 19-mm screens and passively leached for 1 hr in deionized water. Leaching experiments showed that small variations in grain size and leach times had only minor effects on soluble Cl extractions. The short leach time resulted in low Cl concentrations and large (super 36) Cl/Cl errors, but maximized the probability of detecting bomb-pulse (super 36) Cl/Cl signatures. Leachates of 40 VS samples had a mean Cl concentration of 0.141 (+ or -0.026 2Xstandard error) mg/kg rock and a mean (super 36) Cl/Cl ratio of 337 (+ or -45 2Xstandard error)X10 (super -15) (range of 137 to 717X10 (super -15) ). Low Cl concentrations that do not correlate with (super 36) Cl/Cl ratios are consistent with a single, low- (super 36) Cl/Cl meteoric Cl source rather than mixtures of bomb-pulse and rock (or other) sources. Thus, the VS did not independently corroborate earlier results despite efforts to maximize extraction of bomb-pulse Cl and efforts to use core from some of the same boreholes used previously. Differences in sampling, leaching, and analysis are not likely causes for the discrepancies.

The experimental results indicate a strong dependence of the effective Cs+ Kd on the concentrations of other cations, including Na+, which is present at high to extremely high concentrations in fluids leaking from the Hanford SX tanks. The data not only show a dependence of the Cs+ Kd with regard to the aqueous Cs+ concentration, but also with temperature. The focus of this presentation will be on the temperature effect of cesium exchange on Hanford sediments. At 80 degrees C, cesium mobility is about 2 times higher than at 25 degrees C for solutions of similar composition. At low cesium concentrations (5 X 10-7M) cesium retardation increases from Rd = 117 at 80 degrees C to Rd = 282 at 25 degrees C. Similar trends are observed at higher cesium concentrations and higher salt solutions. In 1 M NaNO3 and 10-4M Cs solutions, we report Cs Rd = 17 at 80 degrees C and Rd = 41 at 25 degrees C. In higher salt solutions that are more representative of tank liquours (7.5 M NaNO3) 10-4 M Cs is retarded by a factor of 4 at 80 degrees C and a factor of 8 at 25 degrees C. The decrease in retardation with increasing temperature may be attributed to solution chemistry temperature effects as well as temperature effects of the ion exchange reaction. We will employ Pitzer thermodynamic database together with our multi-site cation exchange model to determine contributions from solution chemistry and ion exchange with the Hanford sediments.

These, and additional new magnetostratigraphic data presented here, derive from drill cores penetrating the Cold Creek flood bar in the Pasco Basin, a depositional sink for much of the material scoured from the Channeled Scabland during Missoula Floods and other similar events. The eastern part of the Cold Creek bar records a magnetostratigraphy characterized by reversed polarity at the base with normal polarity above and reversed polarity on top. We hypothesize that the normal zone is the Jaramillo subchron (0.99-1.07 Ma), or less likely, the Olduvai subchron (1.77-1.95 Ma). We test these possibilities by cosmogenic burial dating (Granger and Musikar, 2001), using the differential radioactive decay of (super 26) Al and (super 10) Be. We sampled 2 paleosols from drill cores of eastern Cold Creek bar as well as 14 kyr Missoula Flood sediments from Badger Coulee for cosmogenic burial dating. We chose the paleosols to increase the likelihood that sufficient cosmogenic nuclides would have accumulated in the samples prior to burial to allow application of this technique. We analyzed the 14 kyr sample to provide an estimate of the inherited cosmogenic nuclide ratio. Measurable inherited concentrations in the same proportion as that produced at the surface would indicate that burial dating could be applied throughout the stratigraphy. If not, then only the paleosols should be dated by this technique. Initial results suggest that sufficient cosmogenic nuclides concentrations are present in these sediments to make burial dating feasible.

Models used to describe chemical transport processes in the vadose zone, however, depend on the reaction kinetics--this is particularly true for naturally derived species like U and Sr. However, dissolution rates of sediments are difficult to quantify due to uncertainties associated with both the amount of reactive surface area available in the sediment and the thermodynamic driving forces for the chemical reactions. Mineral dissolution rates measured in the laboratory typically predict rates that are 2 to 4 orders of magnitude faster than estimates based on field measurements. Such experimental rates, which are commonly measured under far-from-equilibrium conditions, are not broadly applicable to many natural systems. Unfortunately, relatively few field measurements of in situ reaction rates are available, and most of those are on silicate soils. Almost no field measurements exist for deep vadose zone materials or for rocks in the saturated zone. The U-series isotope system can be used to quantify reaction rates in aquifers and thick vadose zone environments. The approach is based on alpha -recoil of (super 234) Th atoms across grain boundaries, which enriches the pore fluid in (super 234) U. Dissolution of the solid phase releases mainly (super 238) U to the pore fluid, so that the (super 234) U/ (super 238) U ratio of the pore fluid is a measure of the local ratio of the dissolution U flux to the alpha -recoil flux. U concentrations and isotope measurements ( (super 234) U/ (super 238) U) are combined with a multicomponent reactive transport model with kinetic treatment of reaction rates in order to constrain reaction rates in the vadose zone at the Hanford Site. U measurements for pore waters, bulk solids, exchangeable and selected mineral phases were conducted on an uncontaminated 70 meter vadose zone core within the 200 West area. The pore water (super 234) U/ (super 238) U activity ratios range from 1.04 to 1.20 in the pore fluids and exchangeable fractions, 1.0 in the bulk solids and from 0.94 to 1.0 in the various size fractions. The measured (super 234) U/ (super 238) U ratios for the vadose zone core yield weathering rates of approximately 10 (super -6.4) yr (super -1) , in general agreement with estimates based on other methods.

Here we describe how long-term chemical weathering rates can be measured for actively eroding landscapes using cosmogenic nuclides together with a geochemical mass balance of weathered soil and parent rock. We tested this approach in the Rio Icacos watershed, Puerto Rico, where independent studies have estimated weathering rates over both short and long timescales. Results from the cosmogenic/mass balance method are consistent with three independent sets of weathering rate estimates, thus confirming that this approach yields realistic measurements of long-term weathering rates. This approach can separately quantify weathering rates from saprolite and from overlying soil as components of the total. At Rio Icacos, nearly 50% of Si weathering occurs as rock is converted to saprolite; in contrast, nearly 100% of Al weathering occurs in the soil. Physical erosion rates are measured as part of our mass balance approach, making it particularly useful for studying interrelationships between chemical weathering and physical erosion. Our data show that chemical weathering rates are tightly coupled with physical erosion rates, such that the relationship between climate and chemical weathering rates may be obscured by site-to-site differences in the rate that minerals are supplied to soil by physical erosion of rock. One can normalize for variations in physical erosion rates using the "chemical depletion fraction", which measures the fraction of total denudation that is accounted for by chemical weathering. This measure of chemical weathering intensity increases with increasing average temperature and precipitation in data from climatically diverse granitic sites, including tropical Rio Icacos and six temperate sites in the Sierra Nevada, California. Hence, across a wide range of climate regimes, analysis of chemical depletion fractions appears to effectively account for site-to-site differences in physical erosion rates, which would otherwise obscure climatic effects on chemical weathering rates. Our results show that by quantifying rates of physical erosion and chemical weathering together, our mass balance approach can be used to determine the relative importance of climatic and nonclimatic factors in regulating long-term chemical weathering rates.

Vesuvius AN - 51736747; 2005-025638 AB - The U-Th/He system can potentially be used for dating volcanic rocks with ages as young as a few thousand years and as old as several million years, thus providing a valuable supplement to radiocarbon and K-Ar dating. Garnet phenocrysts from the 79 AD eruption of Mt. Vesuvius were dated to evaluate the accuracy with which the necessary measurements and corrections can be made. The determined age, corrected for diffusive loss of He, alpha ejection, and initial U-series disequilibrium, is 1885+ or -188 yr which compares well with the known age of 1923 yr. U and Th concentrations were measured by isotope dilution on different aliquots than were used for He concentration measurements. Step-wise degassing yielded an Arrhenius relationship for He diffusion in garnet with an activation energy of 91.31+ or -5.76 kJ/mol and ln D (sub 0) /a (super 2) = -2.00+ or -0.56. The uniformity of U and Th concentrations in garnet was checked by ion microprobe analysis. The (super 234) U/ (super 238) U and (super 230) Th/ (super 238) U activity ratios were measured by MC-ICPMS. The results suggest that with proper analysis and corrections, the U-Th/He method can be used to date young volcanic minerals with useful precision and accuracy, and may therefore be valuable for dating volcanic rocks that have low K or are otherwise difficult to date accurately with Ar-Ar or radiocarbon.

Las Vegas lies above a deep sedimentary basin (maximum depth 5-km) formed by extensional tectonics in the Basin and Range Province. The potential for large earthquakes in the region and possible future nuclear tests at the Nevada Test Site (NTS) expose Las Vegas to seismic risk. Seismologists, computer scientists, engineers at Lawrence Livermore National Laboratory (LLNL), the University of Nevada Reno (UNR) and the University of Nevada Las Vegas (UNLV) are evaluating the response of the basin to seismic ground motion and its effect on structures, with particular emphasis on large structures. Recordings in Las Vegas of earthquakes and historical nuclear explosions at the Nevada Test Site (NTS) have provided valuable constraints on ground motion in the basin. Site response results show that ground motions in the basin can be amplified by factors of 20 or more relative to sites on Las Vegas Valley's periphery. Site response is strongly correlated with basin depth. Additional broadband data have been recorded to augment the coverage of earlier network data. Ground motions are being synthesized using an empirical convolution (transfer function) methodology. Geotechnical investigations of specific sites using ReMi and SASW are being performed to understand the relationship between ground motions and shallow seismic structure. In particular the presence of thick deposits of unconsolidated alluvial fill and strengthening effects of carbonate cementation. Seismic refraction studies are refining the basin depth model reported by Langenheim et al. (2001) based on gravity and seismic reflection. Preliminary results provide constraints on the fill velocities and are consistent with depth-to-basement model. All these results are being integrated into a community geophysical model of the region for use in finite-difference wave propagation calculations. Observed and simulated ground motions from scenario nuclear tests and earthquakes are being used to predict the response of structures in Las Vegas.

It is recognized as being seismically active, containing at least eight tectonically active faults capable of producing mid-scale earthquakes within a highly populated region. In the mid 1950's through the early 1990's, Blume & Associates deployed an array of seismometers in Las Vegas Valley to monitor ground-motions created from nuclear testing at the Nevada Test Site. The coverage area was constrained by the city limits during this era. However, with rapid growth of the City of Las Vegas within the last decade, there is a lack of data within the city's recently expanded northeastern region; the area estimated to be the deepest portion of the basin. To address this issue, Lawrence Livermore National Laboratory (LLNL) and the University of Nevada Las Vegas (UNLV) deployed an array of twelve broadband seismometers in the northern region of the valley in September 2002. These stations recorded data continuously through late January 2003. To better model the depth to basement and basin geometry, differential travel time residuals were calculated through the cross-correlation of P-waves from global teleseismic events. The calculated delay times in the northern regions show variations up to 0.5 seconds over distances of 15 km or less. The residual pattern is consistent across the region and is attributed to zones of thicker basin fill. This supports earlier models of the Las Vegas Basin. Additionally, a collection of regional events in close proximity to the Town of Lavic, in southern California, is inline with the broadband array. The regional Rayleigh and Love waves will be used to calculate the inter-station phase velocity along a portion of the ray path and a phase velocity dispersion curve. This analysis will provide insight to the shear velocity structure of the basin. These studies will contribute to improved models of Las Vegas basin by assessing basin shape, volume, and shear velocity structure of the basin fill. Results of this study will be pertinent to assessing and modeling ground-motions in Las Vegas Valley in the event of an earthquake or future nuclear testing at the Nevada Test Site.

Within Holtwood Gorge, model exposure ages increase with elevation above the modern river bed. The lowest terraces, levels 1 and 2, are 0.25 and 3 m above the modern channel. They yield, respectively, mean exposure ages of 14.0+ or -1.3 ky (n = 11) and 19.2+ or -3.1 ky (n = 25). A single sample from the level 3 terrace (8.5 m above the channel) yields an age of 31.6+ or -3.3 ky. A heavily weathered and eroded high point, standing approximately 20 meters above the modern channel yields a lower limiting age of >97.2+ or -10.5 ky. Model ages for samples collected between the level 2 and 3 terraces range from 17.6+ or -1.9 ky and 23.0+ or -2.5 ky. In order to constrain the spatial and temporal pattern of erosion recorded within the gorge and infer the driving force(s), we collected samples at different spatial scales on each of the three prominent terraces levels. Ages for clusters of three samples 10 to 15 meters apart on both the level 1 and 2 terraces are in tight agreement (50 m drop in sea level during the LGM, implicating climate as the driver of incision. Decreasing ages upstream suggest that this terrace is a time-transgressive surface, sequentially abandoned as the river incised toward level 1 by way of knickpoint retreat. Deglaciation outburst flooding down the Susquehanna River, as suggested by Kochel and Parris (2000, GSA-Abstracts with Programs, v. 32, p.

Such outburst floods are a plausible explanation for the Latest Pleistocene mean model age, the rough surface texture, and lack of an age gradient along the level 1 terrace.

The low-gradient East Range Road piedmont has two major geomorphic surfaces, an incised (up to a few meters) surface proximal to the upland source basins, and a low-relief surface approximately 1 km from the uplands. Activities of (super 10) Be and (super 26) Al decrease exponentially at depth in a 2-meter pit (EP1) dug into the incised surface. A model of the nuclide decrease at depth suggests the upper 2 meters of sediment was deposited approximately 76,000 ka and has been stable (or has had minimal erosion) since. The nuclide-based age of the surface is consistent with the time required to develop a massive Ck/K horizon (stage III) in the bottom meter of sediment. Activities of (super 10) Be and (super 26) Al in a 1.5-meter pit dug into the low-relief surface (EP2) neither increase nor decrease at depth. A model of the nuclide data, when set in the context of soil development--3 buried soil horizons--presents a scenario of three stable surfaces (each lasting between 10,000 and 25,000 years) and each followed by rapid deposition (40 to 250 mm ky (super -1) ). The total time represented in EP2 is between 57,000 to 75,000 years, a range also consistent with the time required to develop the soils present in EP2. Upland basin sediment has the lowest nuclide activity, sediment from the proximal incised piedmont surface has the highest activity, and sediment from the distal low-relief surface has an intermediate nuclide activity. Using a weighted nuclide-mixing model we determined that approximately 75% of sediment in transport down the piedmont erodes from the upland basins while the remaining 25% is eroded from the incised piedmont surface. Nuclide activities of sediment collected from the incised channels and from the low-relief surface increased steadily down the piedmont. Based on the sediment budget and the down piedmont increase in nuclide activity, we modeled average down gradient sediment speeds of 8 to 23 cm y (super -1) .

Complexes that recognize chromatin are defined by several distinct groups of proteins that either directly modify histones or interact with histone-DNA complexes. A protein microarray format was used to analyze the interaction of various DNA repair proteins with chromatin components. We applied proteins, antibodies and DNA to functionalized glass slides and interrogated the slides with our proteins of interest to identify novel protein-protein interactions for proteins involved in DNA double-strand break repair. Here we demonstrate that the DNA repair protein RAD51B, and not its cognate partner RAD51C, interacts with histones and not nucleosomes. Nucleosome-specific interactions were demonstrated with the recently identified SWI/SNF protein, SMARCAL1. Unique RAD51B-histone interactions were corroborated using Far Western analysis. This is the first demonstration of an interaction between RAD51B and histone proteins that may be important for the successful repair of DNA double-strand breaks.

The system is designed to provide early warning to civilians in the event of a terrorist attack. The final APDS will be completely automated, offering aerosol sampling, inline sample preparation fluidics, multiplexed detection and identification immunoassays, and orthogonal, multiplexed PCR (nucleic acid) amplification and detection. The system performance (current capabilities include aerosol collection, multiplexed immunoassays, sample archiving, data reporting, and alarming) was evaluated in a field test conducted in a Biosafety Level 3 facility, where the system was challenged with, and detected, a series of aerosolized releases containing two live, virulent biological threat agents (Bacillus anthracis and Yersinia pestis). Results presented here represent the first autonomous, simultaneous measurement of these agents.

Characteristic mass spectra from individual bacterial endospores of Bacillus subtilis var. niger were obtained in a bipolar aerosol time-of-flight mass spectrometer using a pulsed 266-nm laser for molecular desorption and ionization. Spectra from single spores collected at an average fluence of similar to 0.1 J/cm super(2) frequently contain prominent peaks attributed to arginine, dipicolinic acid, and glutamic acid, but the shot-to-shot (spore-to-spore) variability in the data may make it difficult to consistently distinguish closely related Bacillus species with an automated routine. Fortunately, a study of the laser power dependence of the mass spectra reveals clear trends and a finite number of "spectral types" that span most of the variability. This, we will show, indicates that a significant fraction of the variability must be attributed to fluence variations in the profile of the laser beam.

AN - 73609604; 12950105 AB - De novo aberrations in chromosome structure represent important categories of paternally transmitted genetic damage. Unlike numerical abnormalities, the majority of de novo structural aberrations among human offspring are of paternal origin. We report the development of a three-color fluorescence in situ hybridization (FISH) assay (CT8) to detect mouse sperm carrying structural and numerical chromosomal abnormalities. The CT8 assay uses DNA probes for the centromeric and telomeric regions of chromosome 2, and a probe for the subcentromeric region of chromosome 8. The CT8 assay was used to measure the frequencies of sperm carrying certain structural aberrations involving chromosome 2 (del2ter, dup2ter, del2cen, dup2cen), disomy 2, disomy 8, and sperm diploidy. Analysis of approximately 80,000 sperm from eight B6C3F1 mice revealed an average baseline frequency of 2.5 per 10,000 sperm carrying partial duplications and deletions of chromosome 2. Extrapolated to the entire haploid genome, approximately 0.4% of mouse sperm are estimated to carry structural chromosomal aberrations, which is more than fivefold lower than the spontaneous frequencies of sperm with chromosome structural aberrations in man. We validated the CT8 assay by comparing the frequencies of abnormal segregants in sperm of T(2;14) translocation carriers detected by this assay against those detected by chromosome painting cytogenetic analysis of meiosis II spermatocytes. The CT8 sperm FISH assay is a promising method for detecting structural chromosome aberrations in mouse sperm with widespread applications in genetics, physiology, and genetic toxicology.

AN - 71435134; 14630535 AB - PURPOSETo characterize the cellular functions associated with the altered transcript profiles of mouse brain exposed to low-dose in vivo gamma-irradiation.MATERIALS AND METHODSCerebral RNA was isolated at 30 min and 4 h after whole-body irradiation at 0.1 or 2 Gy, hybridized to random oligonucleotide arrays, and evaluated for time and dose-response patterns by multifactorial analyses.RESULTSBrain irradiation modulated the expression patterns of 1574 genes, of which 855 showed more than 1.5-fold variation. about 30% of genes showed dose-dependent variations, including genes exclusively affected by 0.1 Gy. About 60% of genes showed time-dependent variation with more genes affected at 30 min than at 4 h. Early changes involved signal transduction, ion regulation and synaptic signalling. Later changes involved metabolic functions including myelin and protein synthesis. Low-dose radiation also modulated the expression of genes involved in stress response, cell-cycle control and DNA synthesis/repair.CONCLUSIONSDoses of 0.1 Gy induced changes in gene expression that were qualitatively different from those at 2 Gy. The findings suggest that low-dose irradiation of the brain induces the expression of genes involved in protective and reparative functions, while down-modulating genes involved in neural signalling activity.

Yet whereas numerous magma transport arguments involve hydrous and SiO (sub 2) -rich volcanic products, current clinopyroxene-liquid thermobarometers have been calibrated only from basaltic liquid compositions. To remedy this deficiency, new thermobarometers have been calibrated using new experiments that include hydrated (water-undersaturated) and SiO (sub 2) -rich liquids ranging to 71.3 wt% SiO (sub 2) . As with prior models, the new calibrations are based on jadeite crystallization and jadeite-diopside+hedenbergite exchange equilibria: P(kbar) = -88.3 + 2.82X10 (super -3) T(K)ln {[Jd (super cpx) ] / [Na (super liq) Al (super liq) (Si (super liq) ) (super 2) ]} + 2.19X10 (super -2) T(K)-25.1 ln[Ca (super liq) Si (super liq) ] + 7.03[Mg' (super liq) ] + 12.4 ln[Ca (super liq) ] 10 (super 4) /T(K) = 4.60-4.37X10 (super -1) ln{[Jd (super cpx) Ca (super liq) Fm (super liq) ] / [DiHd (super cpx) Na (super liq) Al (super liq) ]} - 6.54X10 (super -1) ln[Mg' (super liq) ] - 3.26X10 (super -1) ln[Na (super liq) ] - 6.32X10 (super -3) [P(kbar)] - 0.92 ln[Si (super liq) ] + 2.74X10 (super -1) ln[Jd (super cpx) ]. Here, T is in Kelvins and P is in kbar. Jd (super cpx) is the mole fraction of jadeite in clinopyroxene, where pyroxene cations are calculated on the basis of 6 O atoms, and Jd is the lesser of Na or (super VI) Al; remaining Al is used to form CaTs. DiHd (super cpx) is the mole fraction of diopside + hedenbergite in clinopyroxene, calculated as the fraction of Ca remaining after forming CaTs (= (super VI) Al-Jd), CaTiAl (sub 2) O (sub 6) [= ( (super IV) Al-CaTs)/2], and CaCr (sub 2) SiO (sub 6) ? (= Cr/2). Terms such as Al (super liq) refer to the cation fraction of AlO (sub 1.5) in the liquid, Fm (super liq) is the sum FeO (super liq) +MgO (super liq) , and Mg' (super liq) is the cation fraction ratio MgO (super liq) /(MgO (super liq) +FeO (super liq) ). Errors are similar to earlier models that utilize basalt compositions only. For the barometer, R (super 2) = 0.97 and the standard error of estimate (SEE) is 1.7 kbar for the regression data; for the thermometer R (super 2) = 0.96 and the SEE is 33 K. The models are applied to Neogene lavas from the Tibetan Plateau, and Neogene-Quaternary lavas from the eastern Snake River Plain (SRP), Idaho. Crystallization depths for Tibet cluster at the middle/lower crust boundary. Magma-crust density relationships suggest that the middle crust may act as a level of neutral buoyancy. In the SRP, however, magmas appear to bypass several possible density traps. We suggest that fracture properties, such as dike size and aspect ratio, control magma transport in the SRP.

Before this, buffering was primarily accomplished by adjustment of shallow-water carbonate deposition to balance oceanic inputs from weathering on land. Neoproterozoic ice ages of near-global extent and multimillion-year duration and the formation of distinctive sedimentary (cap) carbonates can thus be understood in terms of the greater sensitivity of the Precambrian carbon cycle to the loss of shallow-water environments and CO (sub 2) -climate feedback on ice-sheet growth.

In this paper, we utilize a detailed numerical model of groundwater flow in a region encompassing a large artificial groundwater recharge operation in Orange County, California to evaluate the potential for transport of viruses and protozoan oocysts in such a system, as dictated by a transport model that includes colloid filtration and microbial inactivation components. The purpose of the model is not oriented towards the analysis of any perceived or real microbial contamination, but rather is directed at understanding the influence of aquifer heterogeneity within the modeled system. The transport model is based upon a novel representation of geologic heterogeneity, a high-resolution flow simulator, and an efficient streamline-based transport algorithm. Example virus transport simulations illustrate a large degree of variability in virus breakthrough across water supply pumping wells, with shallower wells providing less than two orders of magnitude of virus removal, and deeper wells indicating many orders of magnitude of virus removal. Simulation results also show variability among pathogens modeled, with Cryptosporidium parvum filtered to a much greater degree than other pathogens. Comparison to transport of an abiotic colloid and a conservative chemical tracer are provided to illustrate the influence of filtration and inactivation on the transport process. The results emphasize the need for improved microbial transport models in realistic aquifer systems, more reliable virus characterization methods and monitoring networks, and their ultimate integration into a broader epidemiological and regulatory framework for aquifer management.

Here we quantify the changes in ocean pH that may result from this continued release of CO sub(2) and compare these with pH changes estimated from geological and historical records. We find that oceanic absorption of CO sub(2) from fossil fuels may result in larger pH changes over the next several centuries than any inferred from the geological record of the past 300 million years, with the possible exception of those resulting from rare, extreme events such as bolide impacts or catastrophic methane hydrate degassing.

AN - 73651610; 12971803 AB - The understanding of beryllium chemistry in human body fluids is important for understanding the prevention and treatment of chronic beryllium disease. Thermodynamic modeling has traditionally been used to study environmental contaminant migration and rarely in the examination of metal (particularly beryllium) toxicology. In this work, a chemical thermodynamic speciation code (MINTEQA2) has been used to model and understand the chemistry of beryllium in simulated human biological fluids such as intracellular, interstitial, and plasma fluids, a number of airway surface fluids for patients with lung conditions, saliva, sweat, urine, bile, gastric juice, and pancreatic fluid. The results show that predicted beryllium solubility and speciation vary markedly between each simulated biological fluid. Formation of beryllium hydroxide and/or phosphate was observed in most of the modeled fluids, and results support the postulation that beryllium absorption in the gastrointestinal tract may be limited by the formation of beryllium phosphate solids. It is also postulated that beryllium is potentially 13% less soluble in the airway surface fluid of a patient with asthma when compared to a "normal" case. The results of this work, supported by experimental validation, can aid in the understanding of beryllium toxicology. Our results can potentially be applied to assessing the feasibility of biological monitoring or chelation treatment of beryllium body burden.

AN - 71378046; 14632059 AB - A commercially available alpha-particle spectrometer and 210Po alpha-particle source were used to determine the mass of microgram quantities of biomolecules. Samples were deposited in microliter volumes on thin silicon nitride windows and dried. The energy loss of the alpha-particles after traversing the sample was converted to a mass using tabulated alpha-particle stopping powers. The measurement was absolute, independent of biomolecule species, and no standards were needed for quantitation. The method has a dynamic range of 0.1-100 microg for deposits of diameter 1-2 mm. The precision varies from approximately 20% at 100 ng to a few percent at 5-100 microg. The silicon nitride windows allow multimodal analysis of the same quantified sample, including PIXE probing of elemental abundances, molecular identification by mass spectrometry, and isotopic quantitation of interactions.

These variations occurred with periodicities similar to those of solar activity and appear to be coherent with time series of the cosmogenic nuclides (super 14) C and (super 10) Be as well as North Atlantic drift ice. Our results imply that small variations in solar irradiance induced pronounced cyclic changes in northern high-latitude environments. They also provide evidence that centennial-scale shifts in the Holocene climate were similar between the subpolar regions of the North Atlantic and North Pacific, possibly because of Sun-ocean-climate linkages.

Radiocarbon dates from three core sites constrain the timing of late Quaternary paleoenvironmental changes in the Central Andes and highlight the site-specific factors that limit the radiocarbon geochronometer. With the exception of mid-Holocene sediments, all cores are generally devoid of macrophyte fragments, thus bulk organic fractions are used to build core chronologies. Comparisons of radiocarbon results for chemically defined fractions (bulk decalcified, humate, humin) suggest that ages derived from all fractions are generally coherent in the post-13,500 yr BP time interval. In the pre-13,500 yr BP time interval, ages derived from humate extracts are significantly younger (300-7000 years) than ages from paired humin residues. Gross age incoherencies between paired humate and humin sub-fractions in pre-13,500 yr BP sediments from all core sites probably reflect the net downward migration of humates. Ages derived from bulk decalcified fractions at our shallow water (90 m) and deep water (230 m) core sites consistently fall between ages derived from humate and humin sub-fractions in the pre-13,500 yr BP interval, reflecting that the bulk decalcified fraction is predominantly a mixture of humate and humin sub-fractions. Bulk decalcified ages from the pre-13,500 yr BP interval at our intermediate depth core site (150 m) are consistently older than humate (youngest) and humin sub-fractions. This uniform, reproducible pattern can be explained by the mobilization of a relatively older organic sub-fraction during and after the re-acidification step following the alkaline treatment of the bulk sediment. The inferred existence of this "alkali-mobile, acid-soluble" sub-fraction implies a different depositional/post-depositional history that is potentially associated with a difference in source material. While internally consistent geochronologies can be developed for the Lake Titicaca sequence using different organic fractions, mobile organic sub-fractions and fractions containing mobile sub-fractions should generally be avoided in geochronology studies. Consequently, we believe humin and/or bulk decalcified ages provide the most consistent chronologies for the post-13,500 yr BP interval, and humin ages provide the most representative ages for sedimentation prior to 13,500 yr BP interval. Using the age model derived from the deep water core site and a previously published isotope-based lake-level reconstruction, we present a qualitative record of lake level in the context of several ice-core records from the western hemisphere. We find the latest Pleistocene lake-level response to changing insolation began during or just prior to the Bolling/Allerod period. Using the isotope-based lake-level reconstruction, we also find the 85-m drop in lake level that occurred during the mid-Holocene was synchronous with an increase in the variability of ice-core delta (super 18) O from a nearby icecap, but was not reflected in any of the polar ice-core records recovered from the interior of Antarctica and Greenland.

Laboratory measured electrical resistivities of samples of sedimentary rocks known to border the fault to the east are comparable to resistivities of the anomalous zone. We suggest that the anomalous region results from conductive sedimentary rocks in a plunging syncline that is adjacent to the fault, rather than caused by fractured rock. If correct, the current surface trace of the San Andreas fault at Middle Mountain does not form the boundary between the Salinian block and the North American plate. Instead, that boundary is approximately 1 km west and collocated with current seismicity. Abstract Copyright Copyright 2003 by the American Geophysical Union.

All but one gave a positive mutagenic response. Fourteen of these samples were analyzed for heterocyclic amine mutagens/carcinogens and all but one contained 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline (MeIQx) and 10 of 14 contained 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) as analyzed by HPLC and confirmed by photodiode array peak matching.

AN - 73560913; 12902424 AB - UNLABELLEDRadioimmunotherapy for non-Hodgkin's lymphoma often results in surprisingly high response rates compared with those expected from estimated absorbed radiation doses. Several factors, including radiobiologic response, selective targeting, and heterogeneous absorbed radiation within the lymphoma, are likely to contribute to the lack of a dose-response relationship. This article investigates the impact of nodal regression on absorbed radiation dose and applies a correction factor to account for its effect.METHODSThe radioactivity in and regression of 37 superficial lymph nodes were measured in 7 non-Hodgkin's lymphoma patients treated with 775-3,450 MBq/m(2) of (131)I-Lym-1 monoclonal antibody. Nodal dimensions were measured with calipers and radioactivity was quantitated using gamma-camera imaging on multiple days after (131)I-Lym-1 injection. Both nodal regression and radioactivity were fit with monoexponential functions. Formulas were developed to account for simultaneous change in nodal mass and radioactivity. All lymph nodes with size and radioactivity measurements, and exponential-fit coefficients of determination of >0.8, were included in the analysis.RESULTSA 3 orders-of-magnitude node-to-node variation in initial radiopharmaceutical concentration (MBq/g) was observed, with the highest concentrations in the smallest nodes. Reduction in radioactivity as a function of time (biologic half-life) varied by about a factor of 2. In contrast, the rate of nodal regression varied by orders of magnitude, from a 14-h half-time to no regression at all. Five nodes regressed with a half-time that was shorter than their observed effective radiopharmaceutical half-life. Accounting for the effect of nodal regression resulted in dose corrections ranging from 1 (no correction) to a factor of >10, with 70% of nodes requiring a correction factor of at least 20% and >50% of nodes requiring a correction factor of >2. Corrected for nodal regression, 46% of nodes analyzed had absorbed radiation doses of >10 Gy and 32% had doses of >20 Gy.CONCLUSIONThese results highlight the importance of accounting for change in mass, particularly tumor regression, when assessing absorbed radiation dose for tissues whose mass changes during the time the radiation dose is being absorbed. The increase in calculated absorbed dose when this change is considered provides better insight into the high nodal response rates observed in non-Hodgkin's lymphoma patients.

AN - 73323885; 12757787 AB - The addition of oxygen-bearing compounds to diesel fuel considerably reduces particulate emissions. TGME and DBM have been identified as possible diesel additives based on their physicochemical characteristics and performance in engine tests. Although these compounds will reduce particulate emissions, their potential environmental impacts are unknown. As a means of characterizing their persistence in environmental media such as soil and groundwater, we conducted a series of biodegradation tests of DBM and TGME. Benzene and methyl tertiary butyl ether (MTBE) were also tested as reference compounds. Primary degradation of DBM fully occurred within 3 days, while TGME presented a lag phase of approximately 8 days and was not completely degraded by day 28. Benzene primary degradation occurred completely by day 3 and MTBE did not degrade at all. The total mineralized fractions of DBM and TGME achieved constant values as a function of time of approximately 65% and approximately 40%, respectively. Transport predictions show that, released to the environment, DBM and TGME would concentrate mostly in soils and waters with minimal impact to air. From an environmental standpoint, these results combined with the transport predictions indicate that DBM is a better choice than TGME as a diesel additive.

Using geomorphology and (super 10) Be cosmogenic radionuclide dating, a succession of moraines from three glaciated valleys is dated to 18-20 ka (Last Glacial Maximum), 15-16 ka (Heinrich Event 1), 12-13 ka (Younger Dryas Stade), and 5-9 ka (early-middle Holocene). These ages substantiate the view that glaciation throughout the American Cordilleras was synchronous during the late Quaternary. Furthermore, these data show that glacial advances in southern California occur when a significant decrease in summer temperature is coupled with an increase in moisture flux producing high winter snowfall. This allows for perennial snow accumulation that may, under appropriate conditions, persist to form glacial ice.

Comparable increases are evident in climate model experiments. The latter show that human-induced changes in ozone and well-mixed greenhouse gases account for nearly 80 per cent of the simulated rise in tropopause height over 1979-1999. Their primary contributions are through cooling of the stratosphere (caused by ozone) and warming of the tropopause (caused by well-mixed greenhouse gases). A model-predicted fingerprint of tropopause height changes is statistically detectable in two different observational ("reanalysis" data sets. This positive detection result allows us to attribute overall tropopause height changes to a combination of anthropogenic and natural external forcings, with the anthropogenic component predominating.

AN - 73500335; 12875410 AB - Electro-osmosis, a coupled-flow phenomenon in which an applied electrical potential gradient drives water flow, may be used to induce water flow through fine-grained sediments. Test cell measurements of electro-osmotic transport in clayey cores extracted from the 27-31 m depth range of the Lawrence Livermore National Laboratory site indicate the importance of pH control within the anode and cathode reservoirs. In our first experiment, pH was not controlled. As a result, carbonate precipitation and metals precipitation occurred near the cathode end of the core, with acidification near the anode. The combination of these acid and base reactions led to the decline of electro-osmotic flow by a factor of 2 in less than one pore volume. In a second experiment, long-term water transport (>21 pore volumes) at stable electro-osmotic conductivity (k(eo) approximately 1 x 10(-9) m2/s-V) was effected with anode reservoir pH > 8, and cathode reservoir pH < 6. Hydraulic conductivity (k(h)) of the same core was 4 x 10(-10) m/s under a 0.07 MPa hydraulic gradient without electro-osmosis. Stable electro-osmotic flow was measured at a velocity of 4 x 10(-7) m/s under a 4 V/cm voltage gradient, and no hydraulic gradient-3 orders of magnitude greater than the hydraulic flow. We also observed chloroform production in the anode reservoir, resulting from electrochemical production of chlorine gas reacting with trace organics. The chloroform was transported electro-osmotically to the cathode, without measurable loss to adsorption, volatilization, or degradation.

Our analysis is based on a multicentury present-day climate simulation performed with an ENSO-resolving Coupled General Circulation Model (CGCM). In consistency with observations, it is found that ENSO variance undergoes changes with a time scale of about 10-20 years. This decadal beat is closely linked to the second dominant pattern of tropical (sub)surface temperature variability. The dipole-like characteristic of this mode is generated mainly by the interplay of horizontal, vertical advection and mixing. We suggest a nonlinear mechanism, which is capable of generating decadal tropical climate anomalies as well as decadal ENSO amplitude modulations (DEAMs) without invoking extratropical dynamics. This mechanism is based on the idea of homoclinic orbits. This new paradigm is validated using a low-dimensional ENSO model that is derived empirically from the CGCM simulation.

These include the degree to which a gene can be silenced, the length of time for which the gene remains silenced, the degree of recovery of gene function, and the effects of the silencing process on general cell functions. We hypothesized that changing the nucleic acid composition of the siRNA constructs used for silencing would affect these parameters. With siRNA gene silencing of the glucose-6-phosphate dehydrogenase gene as a baseline, we found that siDNA molecules have an effect that is similar in duration but lesser in degree, whereas hybrid DNA:RNA molecules have an effect that is enormously greater in both duration and degree.

Cosmogenic radionuclide (CRN) surface exposure dating of moraine boulders defines the timing of each glacial advance and refines the previous glacial chronologies. The CRN data show that glaciation was most extensive during the early part of the last glacial (marine oxygen isotype stage [MIS] 3 and earlier), but limited during MIS 2 (the global Last Glacial Maximum) and the Holocene. A previously assumed Neoglacial advance is dated to 3.6+ or -0.3 ka and the CRN dates confirm a glacial advance ca. 1 ka. These results show that glaciations on the south side of Everest were not synchronous with the advance of Northern Hemisphere ice sheets, yet glaciations within the Himalaya, the world's highest mountain belt, were synchronous during the late Quaternary. The existence of glacial advances during times of increased insolation suggests that enhanced moisture delivered by an active south Asian summer monsoon is largely responsible for glacial advances in this part of the Himalaya. These data allow us to quantify the importance of global climate change and monsoon influence on glaciation in the Himalaya.

The baseline experiment was a long integration of a state-of-the-art-coupled atmosphere-ocean-land general circulation model (GCM). A sensitivity experiment was conducted in which the ocean and atmosphere were fully interactive but the soil moisture was specified. This paper describes a connection found between land-atmosphere coupling and midlatitude sea surface temperature (SST) variability in the North American-North Atlantic sector. Specifying soil moisture results in a reduction in surface and atmospheric temperature variability and also an increase in net heat flux variability. Surface temperature variance is reduced because it is constrained by the fixed soil moistures. Since the surface temperature cannot equilibrate with a given atmospheric anomaly, the resulting heat flux will be quite large and will act to damp the atmospheric anomaly. This is consistent with larger heat flux variance and reduced temperature variance in the simulation with suppressed land processes. SST anomalies in the midlatitude Atlantic are sensitive to air temperature and moisture anomalies modified over the North American continent, so it is not unexpected that SST variance is significantly reduced when land temperature variability decreases. Oceanic "re-emergence" operates in both simulations but is weaker in the fixed soil moisture integration, particularly in a region of the western North Atlantic contiguous with North America. Reemergence is the mechanism by which late winter ocean temperature anomalies are sequestered below the stable summer ocean mixed layer and reentrained into the deepening autumn mixed layer. The larger oceanic anomalies in the fully coupled simulation decay more slowly and are a partial explanation for stronger reemergence. However, during the second winter, the atmospheric forcing favors the same sign of SST anomalies as those reemerging and, therefore, acts to reinforce the anomalies in the fully coupled simulation. An area averaged SST index was constructed for the region of the western North Atlantic where reemergence was most notably reduced. This index was used to construct composites which suggest that, in the fully coupled model, land surface temperature and SST anomalies both reemerge the second winter, whereas in the suppressed land processes simulation, there is no winter-to-winter reappearance of land surface temperature anomalies.

Among other uses, such models are employed both to detect anthropogenic effects in the climate record of the past century and to project future climatic changes due to human production of greenhouse gases and aerosols. CMIP has archived output from both constant forcing ("control run") and perturbed (1% per year increasing atmospheric carbon dioxide) simulations. This report summarizes results form 18 CMIP models. A third of the models refrain from employing ad hoc flux adjustments at the ocean-atmosphere interface. The new generation of non-flux-adjusted control runs are nearly as stable as--and agree with observations nearly as well as--the flux-adjusted models. Both flux-adjusted and non-flux-adjusted models simulate an overall level of natural internal climate variability that is within the bounds set by observations. These developments represent significant progress in the state of the art of climate modeling since the Second (1995) Scientific Assessment Report of the Intergovernmental Panel on Climate Change (IPCC; see Gates et al. [Gates, W. L., et al., 1996. Climate models--Evaluation. Climate Climate 1995: The Science of Climate Change, Houghton, J. T., et al. (Eds.), Cambridge Univ. Press, pp. 229-284]). In the increasing-CO (sub 2) runs, differences between different models, while substantial, are not as great as one might expect from earlier assessments that relied on equilibrium climate sensitivity.

To evaluate internal climate variability, we apply spectral analysis to time series of surface air temperature (SAT) from nine coupled general circulation model (GCM) simulations, three recent global paleotemperature reconstructions, and Northern Hemisphere (NH) instrumental records. Our comparison is focused on the NH due to the greater spatial and temporal coverage and validation of the available NH temperature reconstructions. The paleotemperature reconstructions capture the general magnitude of NH climate variability, but not the precise variance and specific spatial, temporal, or periodic signals demonstrated in the instrumental record. The models achieved varying degrees of success for each measure of variability analyzed, with none of the models consistently capturing the appropriate variability. In general, the models performed best in the analysis of combined mean annual land and marine variability.

This is potentially important for the global climate since the release of latent heat due to condensation of water vapour and fallout of rain from cumulus convection is the most important source for available potential energy in the free troposphere. Beyond this, cumulus convection is a key process in controlling the water vapour content of the atmosphere. The sensitivity of the global climate to modification in rain efficiency of convective clouds due to the suppression of drop coalescence by anthropogenic aerosols is studied by using the atmospheric general circulation model (A-GCM), ECHAM4. This paper presents results from a 15-year sensitivity study, which considers the aerosol effect on warm precipitation formation. Effects on ice processes are not included yet, and therefore the results likely underestimate the magnitude of the full effects due to suppression of precipitation. Instantaneous forcing is large locally (up to 100% reduction of precipitation and the related latent heat release) but confined to small areas, leading to small large-scale mean anomalies in the convective heating and therefore the vertical temperature gradient. We found a definite perturbation of the global circulation, showing distinct sensitivity to the impact of aerosols on suppressing rainfall.

The gravity wave retardation (GWR) method is a simple technique that slows down surface waves and allows a simple explicit integration to be used. Here the method is discussed and applied to a layer model of the tropical Indian Ocean subject to monthly climatological wind forcing. The errors introduced by the GWR method on the barotropic ocean circulation and sea surface elevation are analyzed. Comparison to a model integration with a flat bottom demonstrates that GWR integrations with a speed-up factor up to 16 indeed capture some influence of the bottom relief, in the sense that the GWR solutions have less error than if topography was ignored. Integrations with a speed-up factor of up to 8 are found to model the barotropic circulation well, implying that the GWR method can be applied to climate modelling.

Based on radioactive decay along a water flow path the (super 81) Kr/Kr ratios are directly converted to groundwater residence times. Results are in a range of 225-400 kyr with error bars in the order of 15% primarily due to counting statistics in the cyclotron accelerator mass spectrometer measurement. Additional uncertainties from subsurface production and/or exchange with stagnant porewaters in the confining shales appear to be of the same order of magnitude. These (super 81) Kr ages are then used to calibrate the (super 36) Cl and the (super 4) He dating methods. Based on elemental analyses of rock samples from the sandstone aquifer as well as from the confining Bulldog shale the in situ flux of thermal neutrons and the corresponding (super 3) He/ (super 4) He and (super 36) Cl/Cl ratios are calculated. From a comparison of: (i) the (super 3) He/ (super 4) He ratios measured in the groundwater samples with the calculated in situ ratios in rocks and (ii) the measured delta (super 37) Cl ratios with the (super 4) He concentrations measured in groundwater it is concluded that both helium and chloride are most likely added to the aquifer from sources in the stagnant porewaters of the confining shale by diffusion and/or mixing. Based on this "working hypothesis" the (super 36) Cl transport equation in groundwater is solved taking into account: (i) radioactive decay, (ii) subsurface production in the sandstone aquifer (with an in situ (super 36) Cl/Cl ratio of 6X10 (super -15) ) and (iii) addition of chloride from a source in the confining shale (with a (super 36) Cl/Cl ratio of 13X10 (super -15) ). Lacking better information it is assumed that the chloride concentration increased linearly with time from an (unknown) initial value C (sub i) to its measured present value C = C (sub i) +C (sub a) , where C (sub a) represents the (unknown) amount of chloride added from subsurface sources. Using the (super 81) Kr ages of the four groundwater samples and a reasonable initial (super 36) Cl/Cl ratio of 125X10 (super -15) , which is consistent with other studies in this part of the GAB, it is then possible to determine (C (sub i) ,C (sub a) ) parameter sets for all four samples and consequently to simulate the Cl and the (super 36) Cl evolution with time. Strong evidence that the whole procedure is adequate comes from: (i) a comparison of C (sub i) with the calculated noble gas recharge temperatures (NGRT) indicating that a higher NGRT is related to higher input chloride concentrations C (sub i) (because of higher evapotranspiration) and (ii) a comparison of C (sub a) with the measured (super 4) He concentration confirming the idea that both chloride and helium are added to the groundwater in parallel. It turns out that the four samples fall into two groups: (i) for two of the samples (Raspberry Creek and Oodnadatta) initial (super 36) Cl concentrations are high and (super 36) Cl dating based on radioactive decay is possible. The (super 4) He accumulation rate for these two samples is low (0.2X10 (super -10) cm (super 3) STP (super 4) He/(cm (super 3) water yr)); (ii) for the other two samples (Duck Hole and Watson Creek) the initial (super 36) Cl concentration is low and therefore subsurface processes dominate resulting in almost constant (super 36) Cl concentrations with time; (super 36) Cl groundwater dating is not possible.

The same computer codes were used to construct the atmosphere, ocean, sea ice and land surface components of the two models, and they employ the same types of sub-grid-scale parameterization schemes. The two model versions differ primarily, but not solely, in their spatial resolution. Comparisons are made of results from six coarse-resolution R15 climate change experiments and three medium-resolution R30 experiments in which levels of greenhouse gases (GHGs) and sulfate aerosols are specified to change over time. The two model versions yield similar global mean surface air temperature responses until the second half of the 21st century, after which the R15 model exhibits a somewhat larger response. Polar amplification of the Northern Hemisphere's warming signal is more pronounced in the R15 model, in part due to the R15's cooler control climate, which allows for larger snow and ice albedo positive feedbacks. Both models project a substantial weakening of the North Atlantic overturning circulation and a large reduction in the volume of Arctic sea ice to occur in the 21st century. Relative to their respective control integrations, there is a greater reduction of Arctic sea ice in the R15 experiments than in the R30 simulations as the climate system warms. The globally averaged annual mean precipitation rate is simulated to increase over time, with both model versions projecting an increase of about 8% to occur by the decade of the 2080s. While the global mean precipitation response is quite similar in the two models, regional differences exist, with the R30 model displaying larger increases in equatorial regions.

Though the spatial and temporal pattern of radiative forcing from greenhouse gases differs from that of sunlight, it was shown in a recent study that these schemes would largely mitigate regional or seasonal climate change for a doubling of the atmospheric CO (sub 2) content. Here, we examine the ability of reduced solar luminosity to cancel the effects of quadrupling of CO (sub 2) content. In agreement with our previous study, geoengineering schemes could markedly diminish regional and seasonal climate change. However, there are some residual climate changes: in the geoengineered 4XCO (sub 2) climate, a significant decrease in surface temperature and net water flux occurs in the tropics; warming in the high latitudes is not completely compensated; the cooling effect of greenhouse gases in the stratosphere persists and sea ice is not fully restored. However, these residual climate changes are much smaller than the change from quadrupling of CO (sub 2) without reducing solar input. Caution should be exercised in interpretation because these results are from a single model with a number of simplifying assumptions. There are also many technical, environmental and political reasons not to implement geoengineering schemes.

The composite materials were found to be superior in removing uranium from a stock solution compared to GAC alone evaluated by a modified ASTM D 3860-98 method for batch testing. The testing results were evaluated using a Freundlich adsorption model. The best performing material has parameters of n = 2.87 and K sub(f) = 1169 compared to n = 1.00, and K sub(f) = 20 for GAC alone. The composite materials were formed by mixing (CH sub(3)O) sub(4)Si with the hydrophobic sol-gel precursor, (CH sub(3)O) sub(3)-SiCH sub(2)CH sub(2)CF sub(3) and with specified modifiers, such as H sub(3)-PO sub(4), Ca(NO sub(3)) sub(2), and (C sub(2)H sub(5)O) sub(3)SiCH sub(2)CH sub(2)P(O)(OC sub(2)H sub(5)) sub(2), gelation catalysts, and GAC in a supercritical reactor system. After gelation, supercritical extraction, and sieving, the composites were tested. Characterization by FTIR and super(31)P NMR indicate the formation of phosphate in the case of the H sub(3)PO sub(4) and Ca(NO sub(3)) sub(2) composites and phosphonic acid related compounds in the phosphonate composite. These composite materials have potential application in the clean up of groundwater at DOE and other facilities.

AN - 85370694; pmid-12765392 AB - The theory of time-reversal super-resolution imaging of point targets embedded in a reciprocal background medium [A. J. Devaney, "Super-resolution imaging using time-reversal and MUSIC," J. Acoust. Soc. Am. (to be published)] is generalized to the case where the transmitter and receiver sensor arrays need not be coincident and for cases where the background medium can be nonreciprocal. The new theory developed herein is based on the singular value decomposition of the generalized multistatic data matrix of the sensor system rather than the standard eigenvector/eigenvalue decomposition of the time-reversal matrix as was employed in the above-mentioned work and other treatments of time-reversal imaging [Prada, Thomas, and Fink, "The iterative time reversal process: Analysis of the convergence," J. Acoust. Soc. Am. 97, 62 (1995); Prada et al., "Decomposition of the time reversal operator: Detection and selective focusing on two scatterers," J. Acoust. Soc. Am. 99, 2067 (1996)]. A generalized multiple signal classification (MUSIC) algorithm is derived that allows super-resolution imaging of both well-resolved and non-well-resolved point targets from arbitrary sensor array geometries. MUSIC exploits the orthogonal nature of the scatterer and noise subspaces defined by the singular vectors of the multistatic data matrix to form scatterer images. The time-reversal/MUSIC algorithm is tested and validated in two computer simulations of offset vertical seismic profiling where the sensor sources are aligned along the earth's surface and the receiver array is aligned along a subsurface borehole. All results demonstrate the high contrast, high resolution imaging capabilities of this new algorithm combination when compared with "classical" backpropagation or field focusing. Above and beyond the application of seismo-acoustic imaging, the time-reversal super-resolution theory has applications in ocean acoustics for target location, and ultrasonic nondestructive evaluation of parts.

AN - 73282909; 12751200 AB - The goal of the laser safety officer and any laser safety program is to prevent a laser accident from occurring, in particular, one that causes an injury to a person's eyes. Most laser safety courses "in-house commercial" discuss laser accidents, causes, and types of injury. Many do not address appropriate actions to be taken if such an accident occurs. This article reviews a sampling of laser accidents that have occurred and provides a quick overview of the appropriate steps to take when a laser accident occurs.

AN - 73269344; 12745215 AB - An experimental approach is described for determining protein-small molecule non-covalent ligand binding sites and protein conformational changes induced by ligand binding. The methodology utilizes time resolved limited proteolysis and the high throughput analysis capability of MALDI TOF MS to determine the binding site in a tetanus toxin C-fragment (51 kDa)-doxorubicin (543 Da) non-covalent complex. Comparing relative ion abundances of peptides released from the time resolved limited proteolysis of tetanus toxin C-fragment (TetC) and the TetC-doxorubicin complex every 10 min from 10 to 120 min of digestion revealed that the binding of doxorubicin induced a significant change in surface topology of TetC. Four of the twenty-nine peptides observed by MALDI MS, including amino acids 351-360, 299-304, 305-311 and 312-316, had a lower abundance in the TetC-doxorubicin complex relative to TetC from 10 to 100 min of digestion. A decrease in ion abundance suggests doxorubicin obstructs the access of the protease to one or both termini of these peptides, identifying doxorubicin binding site(s). Conversely, five peptide ions, including amino acids 335-350, 364-375, 364-376, 281-298, and 316-328, all had a greater abundance in the digest of the complex, indicating an increase in accessibility to these sites. These five peptides flank regions of decreased ion abundance, suggesting that doxorubicin not only binds to the surface, but also induces a conformational change in TetC.

In northern Peru (6 degrees S), a stable magnetic component from six Permo-Triassic sites passes fold and reversal tests. The overall mean pole agrees well with Late Permian to Triassic poles from cratonal South America, suggesting this part of Peru has experienced neither significant rotation nor latitudinal transport since the Permo-Triassic. In southern Peru (13 to 16 degrees S), thermal demagnetization isolates stable magnetic components in 16 of 22 Upper Permian to Lower Jurassic sites collected along the transition between the Altiplano and the Eastern Cordillera. These 16 sites are rotated 14 to 147 degrees counterclockwise and pass an inclinations-only fold test. Within the same structural zone, three other Permo-Triassic sites as well as 10 Paleocene sites also show important counterclockwise rotations [Roperch and Carlier, J. Geophys. Res. 97 (1992) 17233-17249; Butler et al., Geology 23 (1995) 799-802]. The large magnitude and exclusively counterclockwise sense of rotation suggest that the tectonic regime included an important sinistral shear component. No correlation exists between rotation amount and rock age, suggesting the rotations are post-Paleocene in age. Because the rotations occur along the fringe of the Eastern Cordillera, they were likely produced during its structural formation, hence from the Late Oligocene to Present. Sinistral shear acting in the northern part of the Bolivian Orocline appears much more pronounced than that north of the Abancay Deflection, which likely arises from differences in convergence obliquity.

The faulting is simulated as a stochastic process with the spatial variation of the key parameters determined by probability distribution functions. The wave propagation from source to site is accounted for by using small earthquake recordings as empirical Green's functions (EGF). This accounts for the regional effects of scattering, attenuation and structure while providing the basis for a broadband (0.5-10 Hz) time history. Because we are interested in sites where the ground motion is expected to be severe, we have included nonlinear wave propagation through the soil. The material properties of the soil column have been determined from laboratory tests, borehole logs and confirmed through seismological modeling of weak motion. We have computed 240 three-component acceleration time histories to represent the range of ground motion one might expect from a M 6.8 earthquake for a site that is located 10 km above the hanging wall of blind thrust (7.1 km closest distance). Based on the suite of time histories we computed a S.D. of 0.45 (natural log units) for the acceleration response spectra in the passband 0.5-10 Hz. The total S.D. (modeling plus parameterization) is 0.6 in natural log units. The mean acceleration response spectrum is near the median 10% in 50-year probabilistic seismic hazard analysis (PSHA) spectrum for the site; the 84% spectrum of the simulations is closer to the 5% in 50 years median spectrum.

The chert clasts were derived from the Senonian Mishash Formation, a chert-bearing chalk, which is widely exposed in the Nahal Zin drainage basin, the drainage system that supplied most of the material to the beach ridges. Simple exposure ages, assuming only exposure at the beach ridge sampling sites, range from 35 to 354 ky; using the ratio (super 26) Al/ (super 10) Be, total clast histories range from 0.46 to 4.3 My, unrelated to the clasts' current position and exposure period on the late Pleistocene beach ridges, 160-177 m below sea level. Optically stimulated luminescence dating of fine sediments from the same and nearby beach ridges yielded ages of 20.0+ or -1.4 ka and 36.1+ or -3.3 ka. These ages are supported by the degree of soil development on the beach ridges and correspond well with previously determined ages of Lake Lisan, which suggest that the lake reached its highest stand around 27 000 cal. years BP. If the clasts were exposed only once and than buried beyond the range of significant cosmogenic nuclide production, then the minimum initial exposure and the total burial times before delivery to the beach ridge are in the ranges 50-1300 ky and 390-3130 ky respectively. Alternatively, the initial cosmogenic dosing could have occurred during steady erosion of the source bedrock. Back calculating such rates of rock erosion suggests values between 0.4 and 12 m My (super -1) . The relatively long burial periods indicate extended sediment storage as colluvium on slopes and/or as alluvial deposits in river terraces. Some clasts may have been stored for long periods in abandoned Pliocene and early Pleistocene routes of Nahal Zin to the Mediterranean before being transported again back into the Nahal Zin drainage system and washed on to the shores of Lake Lisan during the late Pleistocene.

Three systems were examined: (1) a column packed with homogenized aquifer material, (2) undisturbed aquifer cores, and (3) a section of a semi-confined alluvial aquifer encompassing approximately 2000 m (super 2) . Tracer experiments were conducted using non-reactive tracers with different aqueous diffusion coefficients, based on the assumption that the impact of diffusion-mediated mass-transfer processes on solute transport will be dependent upon the magnitude of the diffusion coefficient. For the homogenized packed column, the breakthrough curves for the different tracers were very similar, and the attendant dispersivities were identical. These results indicate, as would be expected, that physical-heterogeneity related diffusive mass transfer did not measurably contribute to solute transport in the homogeneously packed column. Conversely, the results obtained for the undisturbed aquifer cores indicate that diffusive mass transfer, possibly associated with diffusion between zones of lower and higher advection, contributed to solute transport in this system. For the field test, the magnitudes of the dispersivity coefficients were different for the different tracers. Thus, solute transport at the field scale appeared to be influenced by diffusive mass transfer, most likely associated with mass transfer between regions of lower and higher permeability. These results illustrate that tracer tests using tracers with different diffusivities can be used to help elucidate the relative contribution of diffusion-mediated mass transfer to solute transport.

The microbial growth results from the introduction of water, ground support, and waste package materials into the deep unsaturated rock. The simulations, which spanned 1 million years, were accomplished using a newly developed computer code, Microbial Impacts to the Near-Field Environment Geochemistry (MING). MING uses environmental thresholds for limiting microbial growth to temperatures below 120 degrees C and above relative humidities of 90% in repository drifts. Once these thresholds are met, MING expands upon a mass balance and thermodynamic approach proposed by McKinley et al. [FEMS Microbiol. Rev. 20 (1997) 545] by using kinetic rates to supply constituents from design materials and constituent fluxes including solubilized rock components into the drift to perform two separate mass balance calculations as a function of time. The first (nutrient limit) assesses the available nutrients (C, N, P and S) and calculates how many microorganisms can be produced based on a microorganism stoichiometry of C (sub 160) (H (sub 280) O (sub 80) )N (sub 30) P (sub 2) S. The second (energy limit) calculates the energy available from optimally combined redox couples for the temperature and pH at that time. This optimization maximizes those reactions that produce >15 kJ/mol (limit on useable energy) using an iterative linear optimization technique. The final available energy value is converted to microbial mass at a rate of 1 kg of biomass (dry weight) for every 64 MJ of energy. These two values (nutrient limit and energy limit) are then compared and the smaller value represents the number of microorganisms that can be produced over a specified time. MING can also be adapted to investigate other problems of interest as the model can be used in saturated and unsaturated environments and in laboratory situations to establish microbial growth limitations. Other projected uses include investigations of contaminated locations where monitored natural attenuation or engineered bioremediation could be employed.

The most straightforward approach is to account for the 3-D drift- and mountain-scale dimensionality all within a single monolithic thermohydrologic model. This approach is too computationally expensive to be a viable simulation tool capable of addressing all waste-package locations in the repository. The Multiscale Thermohydrologic Model (MSTHM) is a computationally efficient alternative to addressing these modeling issues. In this paper, we describe the principal calculation stages to predict temperature, relative humidity, and liquid-saturation, as well as other thermohydrologic variables, in the drifts and in the host rock. Using a three-drift repository example (which is a scaled-down version of the proposed repository), we demonstrate the validity of the MSTHM approach against a nested monolithic thermohydrologic model.

These include a Higher-Temperature Operating Mode (HTOM), which results in a localized boiling zone around each emplacement drift, and a Lower-Temperature Operating Mode (LTOM), which always maintains sub-boiling temperatures throughout the repository. The HTOM places all waste packages nearly end to end, making the lineal power density greater than in the LTOM. The lower lineal power density in the LTOM was achieved by placing some waste packages farther apart (which results in a larger repository footprint), and through an increased reliance on pre-closure ventilation to remove the waste-package-generated heat. We focus on temperature T and relative humidity RH at the waste-package and drift-wall surfaces, and on in-drift evaporation. In general, HTOM temperatures are greater than corresponding LTOM temperatures, exhibit similar spatial variability and have a stronger dependence on infiltration flux. The duration of RH reduction on waste packages is similar for the LTOM and HTOM. A major difference between the LTOM and HTOM is the lower waste-package temperature at any given value of waste-package RH for the LTOM. Waste-package temperatures in the LTOM, by design, remain below approximately 85 degrees C; the absence of RH reduction arising from host-rock dryout causes waste-package RH to remain above about 40%. The HTOM waste packages experience higher temperatures and correspondingly lower RH conditions as a result of RH reduction arising from host-rock dryout. For most of the repository area, the HTOM delays the potential onset of gravity-driven seepage compared to the LTOM (as indicated by the duration of boiling at the drift wall). Boiling conditions in the HTOM also delays the onset of capillary-driven seepage into the granular invert, causing the HTOM to have less evaporation in the invert during the first 800-1500 years than the LTOM; subsequent evaporation rates are higher in the HTOM, due to the higher power density.

The validation of such numerical codes can be accomplished by comparison of numerical simulations against appropriate analytical solutions. In this paper, we present analytical solutions for the reactive transport of N-member radionuclide chains (i.e., multiple species of radionuclides and their daughter species) through a discrete fracture in a porous rock matrix applying a system decomposition approach. We consider the transport of N-member radionuclide chains in a single-fracture-matrix system as a starting point to simulate more realistic and complex systems. The processes considered are advection along the fracture, lateral diffusion in the matrix, radioactive decay of multiple radionuclides, and adsorption in both the fracture and matrix. Different retardation factors can be specified for the fracture and matrix. However, all species are assumed to share the same retardation factors for the fracture and matrix, respectively. Although a daughter species may penetrate farther along the fracture than its parent species when a constant-concentration boundary condition is applied, our results indicate that all species retain the same transport speed in the fracture if a pulse of the first species is released into the fracture. This solution scheme provides a way to validate numerical computer codes of radionuclide transport in fractured rock, such as those being used to assess the performance of a potential nuclear-waste repository at Yucca Mountain.

This monitoring activity is intended to establish the extent to which predicted behavior matches the actual response of the geological system to waste emplacement. To accomplish this goal, field measurements must be made at a spatial resolution that will determine whether the changes in parameters that are monitored conform to predicted evolutionary patterns. From the perspective of thermohydrological and geochemical parameters, key measurements will consider pore water compositional evolution and changes in matrix and fracture saturation in the near vicinity of waste emplacement tunnels. A massively parallel high performance computational platform (a 1200 processor IBM SP-2) was used to conduct three-dimensional, high resolution simulations to ascertain the spatial variability to be expected during a monitoring period. The results show that spatial variability in certain chemical parameters below waste emplacement tunnels provides robust targets for monitoring, but will require sampling on the scale of 10 s of centimeters in some locations, in order to rigorously test models. Chemical variability induced by relatively small changes in waste package heat output suggests that designing a monitoring program that will rigorously test model predictions will likely require high resolution, three-dimensional simulations of the "as-built" monitoring tunnels.

To confirm and extend these results we evaluated 22 phosphine appliers and 26 controls matched for age and smoking status. Two independent methods were used to evaluate exposure: fluorescence in situ hybridization (FISH) with whole-chromosome paints of chromosomes 1, 2, and 4 labeled in a single color to quantify translocations in peripheral lymphocytes, and the glycophorin A (GPA) assay to quantify phenotypically mutant (NO or NN) erythrocytes. No differences in the frequency of translocations were found in the phosphine appliers compared to the controls, and no effect of cigarette smoking was observed. However, a significant increase in the frequency of translocations with age (P0.0001) was seen. No effect of phosphine exposure or cigarette smoking was observed in the GPA assay. These results are in contrast to previous findings from this same population which showed an increase in chromosome aberrations among phosphine appliers. The results are most easily interpreted as supporting the effectiveness of the personal protective equipment that is now worn by the workers but which was not employed prior to and during the earlier studies.

In both blind and standard laboratory trials, we demonstrate the simultaneous detection of four simulant agents from a single sample. The challenge agents comprise broad classes of pathogens (virus, protein toxins, bacterial spores, vegetative cells). Assay performance of each analyte was optimized, and dose-response curves and the limits of detection (LODs) for individual analytes are presented. Assay performance, including dynamic range, sensitivity, and LODs for liquid arrays and enzyme-linked immunosorbant assay were compared and are shown to be similar. Maximum assay sensitivity is obtained in similar to 1 h, and good sensitivity is achieved in as little as 30 min. Although the sample matrixes are very complex, even for highly multiplexed assays the samples do not exhibit evidence of nonspecific binding, demonstrating that the assays also have high specificity.

The Holocene sequence indicates a greater variability in circulation than previously detected. During the early Holocene, ca. 9 ka, B-P (super 14) C apparent age differences fluctuated between 220 and 560 (super 14) C yr, similar to rapid variations seen during the Younger Dryas and the last glacial episode. During the relatively stable middle Holocene (8.5-2 ka), B-P (super 14) C apparent age differences averaged 440 (super 14) C yr. After 2 ka, the average B-P (super 14) C apparent age difference increased to 620 (super 14) C yr, which has persisted until the present. The shift in B-P (super 14) C apparent age differences likely represents a change in the strength or source of North Pacific Intermediate Water production and is concurrent with changes in regional climate patterns as well as with changes in temperature and accumulation rates measured in the Greenland Ice Sheet Project 2 ice core, suggesting large-scale changes in atmospheric circulation patterns.

We combine the resulting mixing model with existing cosmogenic radionuclide methods that quantify river inputs and terrace ages to determine the major components of the long-term littoral sediment budget of the Santa Cruz, California, coastline. Sediment derived from coastal basins eroding at 0.2 mm/yr has a much lower concentration than sediment derived from 60-84 ka terrace sands atop backwearing seacliffs. The complex pattern of cosmogenic radionuclide concentrations in littoral sands along >100 km of coastline can be explained by mixing sediment derived from seacliffs backwearing at 10 cm/yr with that delivered by rivers having widely different amounts of sediment discharge.

Whereas active faults are present along most of the west side of the SEM, no active faults have been mapped at the surface on the east side where the erosional and depositional effects of the Colorado River have sculpted the range front. A series of at least four stepped strath terraces and an upper pediment surface are present along much of the eastern range flank. The strath and pediment surfaces all dip 1-2 degrees away from the range, and the differences in height between each terrace typically are 1 to 3 m. The strath terraces are cut into fine-grained fluvial-deltaic deposits and are capped by gravel deposits ( approximately 1 m thick). The fluvial-deltaic deposits probably formed when the Colorado River delta graded to the 125 ka Sangamonian high sea level stand at 7 m above present sea level (Carter, 1977). Given that these deposits are now approximately 20 m above the present floodplain, it is likely that approximately 13 m of uplift has occurred in this region since their deposition. The capping pediment and terrace gravels were dated using optically stimulated luminescence (OSL) and (super 10) Be cosmogenic radionuclide (CRN) depth-profile methods. The OSL ages range from approximately 20 to 28 ka, whereas the CRN ages scatter from 45 to 128 ka. We interpret the CRN ages to reflect inheritance due to exposure prior to final deposition and the OSL ages to represent the time of deposition of the capping gravels. Therefore, the formation and capping of the pediment and strath surfaces occurred 20-28 ka at a time when sea level was falling during the last glacial cycle. At this time, the Colorado River may have been entrenched immediately east of the SEM causing local base level to be 10's of meters lower. Sequential strath incision is interpreted to have occurred during this base-level lowering, but may have been punctuated by tectonic uplift. Since the time of high sea level deltaic deposition 125 ka, the deltaic deposits have been uplifted with average surface uplift rates of approximately 0.1 mm/yr. However, this rate may be higher if some of the high-stand fluvial-deltaic deposits were removed by erosion prior to pediment formation and/or if the pediment and strath surfaces graded to an entrenched Colorado River located just east of the SEM at 20-28 ka.

Recharge of groundwater takes place through the vadose zone, where complex interactions between thermal-hydrological-geochemical processes affect water quality. Monitoring processes in the vadose zone is an important means of evaluating the long-term health of aquifer systems, and has become an integral part of many subsurface engineering efforts. Monitoring such systems, however, may be affected by changes in climate that slowly propagate through vadose zone systems. We describe in this paper the use of NUFT-C, a reactive transport simulator designed to run on a high performance, massively parallel computer, to compare quantitatively the evolution of a deep vadose zone with changes expected from an engineered high-level nuclear waste repository. The results suggest that the impacts from waste emplacement are, in some instances, similar to those that would be observed as a result of climate change, whereas others are distinguishable from evolution of the natural system. Such simulations facilitate design of long-term monitoring programs that take account of these complex effects. The results emphasize the importance of developing long-term baseline measurements and control sites, in order to enhance confidence in interpretations of complexly evolving data sets that will be obtained from multidecade monitoring efforts.

The pCO (sub 2) was decreased by increasing Antarctic sea ice in a seven-box model of the world ocean, and another model showed a similar response to Southern Ocean stratification. In box models the pCO (sub 2) of the atmosphere is controlled by the region of the surface ocean that fills the deep sea By severing the Southern Ocean link between the deep sea and the atmosphere; atmospheric pCO (sub 2) in these models is controlled elsewhere and typically declines, although the models range widely in their responses. "Continuum models," such as three-dimensional (3-D) and 2-D general circulation models, control pCO2 in a more distributed way and do not exhibit box model sensitivity to high-latitude sea ice or presumably stratification.

New cosmogenic isotope measurements from upland bedrock surfaces and erratics along the northeastern margin of the Laurentide Ice Sheet (LIS) shed light on this debate. (super 10) Be and (super 26) Al concentrations from three perched erratics, yielding cosmogenic exposure ages of 17-11 ka, are much lower than those measured in two unmodified, highly weathered tors upon which they lie, which yield cosmogenic exposure ages of >60 ka. These findings suggest that non-erosive ice covered weathered upland surfaces along the northeastern margin of the LIS during the last glacial maximum. These data challenge the use of relative weathering to define the margins of Pleistocene ice sheets. The juxtaposition of non-erosive ice over upland plateaus and erosive ice in adjacent fiords requires strong gradients in basal thermal regimes, suggestive of an ice-stream mode of glaciation.

The process has been used to print coils on a variety of materials, including glass and Teflon. The dimensions of these coils can be varied easily to allow any number of different coil designs, including solenoids and saddle coils. In our fabrication process, capillary tubes sputter-coated with a thin titanium-copper multilayer are plated with a positive electrodeposited photoresist. The resist is exposed with a computer-controlled laser-lathe apparatus consisting of an argon-ion laser, an acousto-optic modulator, a movable aperture, a lead screw stage and a spindle stage. After exposure and development, copper is electrolytically deposited through the resist mask. Following copper deposition the resist mask is removed and the sputtered copper and titanium are etched away, leaving a microcoil firmly adhered to the capillary. The resistivity of the laser-lathe copper windings is 7.6% higher than the resistivity of hand-wound coils (1.85 mu Omega -cm for laser-lathe copper compared with 1.72 mu Omega -cm for bulk annealed copper). For laser-lathe and hand-wound microcoils of similar size and geometry, the coil quality factor, Q, of the laser patterned coils would be 7.6% lower than the hand-wound coils. Examples of super(13)C NMR spectra obtained using laser-lathe coils are shown, and a relative improvement of 68 in the NMR sensitivity is calculated for a laser-lathe microcoil compared with a conventional 5 mm NMR sample tube.

These same isolates were characterized with respect to plasmid copy number by using a novel method of quantitative PCR developed for rapid and efficient detection of B. anthracis from environmental samples. We found that the copy numbers for both pXO1 and pXO2 differed from those in previously published reports. By combining the data on survival, plasmid copy numbers, and clonality, we developed a model predicting virulence. This model was validated by using a randomly chosen set of 12 additional B. anthracis isolates. Results from this study will be helpful in future efforts to elucidate the basis for variation in the virulence of this important pathogen.

AN - 73167472; 12675491 AB - Benzene is both an environmental pollutant and a component of cigarette smoke, gasoline, and automotive emissions. Although occupational exposure to benzene has been shown to cause blood disorders and cancer in humans, the potential health effects resulting from exposure to low levels of benzene are not known. The goals of this project were to determine how well benzene is metabolized and to assess its binding to macromolecules in rodents at doses more closely mimicking human environmental exposure. To determine whether genotoxic metabolites of benzene are produced at environmental exposure levels. various doses of 14C-benzene were given intraperitoneally to male B6C3F1 mice at doses from 5 ng/kg to 500 mg/kg body weight. Samples of urine, plasma, liver, and bone marrow were taken at selected times up to 48 hours after exposure. Individual benzene metabolites in the samples were measured by accelerator mass spectrometry (AMS*). Metabolites were quantified by determining the area under the curve (AUC) for 24 to 48 hours. The major metabolites found in urine were an unidentified radiolabeled metabolite. phenyl sulfate, phenyl glucuronide. and muconic acid (an indicator of muconaldehyde formation). The major metabolites found in plasma, liver, and bone marrow samples were muconic acid and hydroquinone. Only liver showed a dose response for hydroquinone and muconic acid. The kinetics of both DNA and protein adduct formation were assessed over 48 hours at a 14C-benzene dose of 5 microg/kg body weight. A dose-response study was then conducted using 14C-benzene doses from 5 ng/kg to 500 mg/kg body weight in B6C3F1 mice. Adduct levels were determined by AMS in liver and bone marrow. DNA and protein adducts in liver reached maximum levels 30 minutes after benzene administration, whereas those in bone marrow reached maximum levels after six hours. Both protein and DNA adduct AUCs were greater in bone marrow than in liver. Dose-response assessments at both 1 and 12 hours showed that DNA and protein adducts in liver and bone marrow were dose dependent over doses spanning eight orders of magnitude. Consistent with the benzene metabolism data, these data show that reactive forms of benzene were present in liver and bone marrow after exposure to human-relevant benzene levels. Thus, at low doses, benzene was absorbed and metabolized into reactive intermediates capable of binding to DNA and protein. The relation between benzene metabolism and macromolecular binding was examined by comparing benzene macromolecular adduct formation among strains of male mice (B6C3F1, DBA/2, and C57BL/6) and male rats. These animals have been reported to have different metabolic capacities for benzene and also different tumorigenic and cytotoxic responses to benzene exposure. We hypothesized that differences in the capacity to metabolize benzene affect macromolecular adduct formation and that the amount of macromolecular damage is related to benzene's ability to cause cancer and other blood disorders. 14C-benzene was administered intraperitoneally to all rodents (5 microg/kg body weight) and adduct levels were determined by AMS at selected time points up to 48 hours after exposure. AUCs for protein and DNA adducts in bone marrow, the primary target organ for benzene toxicity, decreased in the following order: B6C3F1, DBA/2, C57BL/6, and rats. Similarly, adduct AUCs in liver were greater in B6C3F1 mice than in rats although the trend was less clear for the DBA/2 and C57BL/6 mouse strains. The results of this work are consistent with previously published work showing that the ability to metabolize benzene follows a similar pattern with these animals and is consistent with the tumorigenicity of benzene in mice and rats. Thus, our data suggest that benzene toxicity is related to the ability to produce macromolecular adducts. Preliminary studies were conducted to assess adduct dosimetry after low-dose inhalation of benzene. Inhalation methods were developed to administer a nominal body burden of 5 microg benzene/kg body weight. Then, 14C-benzene was administered to B6C3F1 mice and rats by both intraperitoneal (IP) administration and by inhalation, and DNA and protein adducts in liver and bone marrow were analyzed by AMS. AUCs for adduct levels were greater after IP benzene administration than after inhalation of benzene. Adduct levels were greater in DNA from B6C3F1 mouse bone marrow than in DNA from liver regardless of exposure route. Collectively, these data show that the internally reactive dose was greater when benzene exposure was by IP administration. In summary, the results suggest that benzene is metabolized to reactive forms capable of binding both protein and DNA in target and nontarget organs of rats and mice at doses encountered by humans through environmental exposure. Macromolecular binding was dose-dependent at low doses of benzene and reflected benzene toxicity, based on its carcinogenicity and ability to cause other blood-related disorders. These data are consistent with macromolecular adducts being indicative of benzene exposure and benzene toxicity although much more research is needed to validate this point. Additionally, benzene metabolism varies among species and among strains within a species of rodent. Thus data are needed in humans to understand how to use the rodent data in risk assessment and ultimately to determine whether macromolecular adducts are a useful indicator of exposure and a useful predictor of risk.

Results suggest spatially homogeneous sediment generation (on the 10 (super 4) -10 (super 5) yr time scale and >100 km (super 2) spatial scale) at 73+ or -11 t km (super -2) yr (super -1) , equivalent to 27+ or -4 m/m.y. of bedrock erosion. This rate is consistent with rates derived from fission-track, long-term sediment budget, and sediment yield data, all of which indicate that the Great Smoky Mountains and the southern Appalachians eroded during the Mesozoic and Cenozoic at approximately 30 m/m.y. In contrast, unroofing rates during the Paleozoic orogenic events that formed the Appalachian Mountains were higher (> or =10 (super 2) m/m.y.). Erosion rates decreased after termination of tectonically driven uplift, enabling the survival of this ancient mountain belt with its deep crustal root as an isostatically maintained feature in the contemporary landscape.

By using multiple backhoe trenches and radiocarbon dating of wood and charcoal, we determined the history of five small fans (1900-14,850 m (super 3) ) that range in age from historic to > or =13,320 calibrated (cal.) (super 14) C yr B.P. Three fans located on river terraces have depositional records whose ages are limited by the age of the terrace on which they are situated. Two other fans, located in glacial valleys, preserve records that extend back nearly to deglaciation. The stratigraphy of all five fans contains evidence suggesting episodic activity, including scoured surfaces and layers of gravel and cobbles. Periods of little or no activity are indicated by development of now-buried soils. Dated sand and gravel strata in several fans suggest correlative periods of increased sediment yield and by inference, runoff, at ca. 9650-9340 and 6900-6020 cal. (super 14) C yr B.P. Soils preserved within at least two of the five fans suggest lower sediment yield at ca. 12,900, ca. 5500, ca. 4300, and ca. 3200 cal. (super 14) C yr B.P. At least three of the fans aggraded rapidly during the past several hundred years in response to land clearance and disturbance; however, many aggradation and scour events in the Holocene cannot be correlated definitively between fans because of the discontinuous nature of gravel beds and the lack of radiocarbon-datable material in the coarsest strata. Drainage-basin sediment yields implied by the fan volumes and integrated over the Holocene are quite low, > or =4-11X10 (super 3) kg.km (super -2) .yr (super -1) . Sediment yields since settlement by European and other immigrants are several to hundreds of times higher, demonstrating the connections among forest clearance, agriculture, and increased erosion rates of New England hillslopes.

The seismic reflections were excited by a drill bit moving along a horizontal well at a depth of 2800 m. The data were recorded by a receiver array on the surface. There were 609 twenty-second traces recorded at each of 10 three-component stations. After preprocessing, the traces were autocorrelated and migrated. Two imaging conditions were examined. The ghost-reflection imaging condition produced a reflectivity section that agreed with a nearby common-depth-point section. The migration section obtained with a primary-reflection imaging condition produced a reflectivity section inferior in quality to that of the ghost image. A possible explanation is that the drill-bit location was not precisely known, which can be shown to induce weak errors in the ghost-imaging condition but stronger errors in the primary-reflection imaging condition. Ghost migration images reflections not only below the drill bit, but also above the drill bit. This investigation is one of the first examples of successfully imaging the earth's reflectivity section from horizontal drill-bit data, and it offers a potentially useful method for seismic imaging from drill-bit data.

The results of applying this method yield source spectra that are more stable than any other direct-phase measure to date. The procedure accounts for all propagation, site, and S-to-coda transfer function effects. The resultant coda-derived moment-rate spectra are then used to provide traditional band-limited magnitudes (e.g., M (sub L) , m (sub b) ), as well as an unbiased, unsaturated magnitude (moment magnitude, M (sub w) ) that is tied to a physical measure of earthquake size (i.e., seismic moment). We validate our results by comparing our coda-derived moment estimates with those obtained from long-period waveform modeling. Most importantly, we demonstrate that the interstation magnitude scatter is significantly reduced when using long-window-length coda (i.e., M (sub w) (coda) and m (sub b) (coda)). However, when we use short-window coda measurements of 5 sec in length taken after twice the direct-wave travel time, the scatter remains large, comparable to direct waves. Once calibrated, the coda-derived source spectra provide stable, unbiased magnitude estimates for events that are too small either to be reliably waveform modeled or to be seen at far-regional and teleseismic distances. This property is ideal for sparse local or regional networks. We found that our source amplitude estimates were nearly insensitive to the expected source radiation pattern and exhibited roughly a factor of 3-5 less interstation scatter when compared against coda duration and conventional direct-phase measurements (e.g., P (sub g) , L (sub g) ). We also found that the coda stability, as measured by the interstation scatter for common events, reached a minimum value beyond a certain critical measurement window length. For example, at 6-8 Hz, the interstation standard deviation was less than 0.08 provided the coda measurement was at least approximately 80 sec in duration, whereas at 1.5-2.0 Hz, the critical window length was approximately 100 sec. For all frequency bands, as the coda window becomes shorter, the standard deviation increases, asymptotically approaching the direct-wave scatter. In this article we describe in detail the calibration methodology and address concerns related to choosing optimal measurement window lengths, estimating error, testing empirical path corrections, and tying coda amplitudes to an absolute scale. In order to demonstrate the usefulness and transportability of our method, we chose the Dead Sea Rift as our study area.

In source areas, located in the immediate vicinity of the contaminant releases, the contaminants are distributed in relatively high concentrations throughout the vadose zone and below the water table in both fine-grained and coarse-grained sediments. In distal portions of the plume, downgradient of the source areas, the contaminants: 1) are primarily limited to coarse-grained zones, 2) are usually orders of magnitude lower in concentration than in the source areas, and 3) have slightly diffused into the bordering aquitards but should not significantly affect the approach to or achievement of cleanup goals. The cleanup strategy for this distribution of contaminants calls for the hydraulic isolation of the source area followed by aggressive remediation of both the source and distal areas of the plume as needed to achieve remediation objectives most efficiently. In contrast to some of the currently perceived limitations of pump-and-treat remediation, our data and analyses indicate that distal portions of contaminant plumes can be expeditiously remediated, perhaps in less time than it took the contaminants to be transported to their preremediation locations.

Recently, the procedures used by the group at the Australian National University (ANU) for the hydro-isostatic component of the theory have been questioned (Quat. Sci. Rev. 21 (2002) 409) although the details of the ANU group's procedures have not been published because they are mainly computational in nature rather than representing significant conceptual advances. Because of this criticism, we set out here in detail the procedures that have been used for the treatment of the migration of shorelines as sea levels rise and fall, the effect of retreat and advancing grounded ice on shelves and shallow seas, and the transitions from grounded to floating ice (and vice versa). We conclude that there is no basis for the criticism, that these formulations and their implementation provide a high resolution and complete description of both sea-level change and of the estimates of volumes of ice exchanged with the oceans. The results from this formulation are confirmed by the entirely independent analyses of Milne et al. (Quat. Sci. Rev. 21 (2002) 361) and Mitrovica and Milne (Geophys. J. Int. (2002), submitted for publication) who conclude that our formulation is significantly more accurate than the procedure advocated by Peltier (Science 265 (1994) 195; Rev. Geophys. 36 (1998a) 603, Geophys. Res. Lett. 25 (1998b) 3955).

Chlorine-36 end member compositions are defined for both recharge and chemically evolved groundwater components. The geochemical evolution of super(36)Cl is strongly controlled by water-rock interaction with Paleozoic carbonate rocks that comprise the regional aquifer system, resulting in chemically evolved groundwater that is characteristically low in super(36)Cl/Cl and high in Cl. Groundwater from alluvial and volcanic aquifers that overlie the regional carbonate aquifer are generally characterized by high super(36)Cl/Cl and low Cl signatures, and are chemically distinct from water in the regional carbonate aquifer. This difference provides a means of examining vertical transport and groundwater mixing processes. In combination with other geochemical and hydrogeologic data, the end members defined here provide constraints on aquifer residence times and mixing ratios.

This process is notoriously difficult to model, given the complexity of the turbulent boundary layer and chemistry of the three-phase interface (air, liquid, solid) typically found at the land surface. Wind tunnel studies have demonstrated the importance of resuspension within a short time after deposition, but there exists no robust model for short-term resuspension. Numerical simulations of accidental or terrorist releases of hazardous materials need such a model to accurately predict fate and transport of the materials within hours to days after release. Many accepted conventional models were derived from resuspension data for aged sources, such as former weapons test sites; these data sets, and the associated models, may not be appropriate for short-time resuspension. The study described here reexamined historical wind tunnel data on short-term resuspension, with the goal of developing a model appropriate for numerical simulations. Empirical models are derived from these data using a suite of parameters (friction velocity, particle diameter, surface roughness, particle density, and time). These empirical models, and the wind tunnel data, are compared quantitatively with existing conventional models from the literature. The conventional models underpredict short-time resuspension, resulting in order-of-magnitude errors in predictions of resuspended mass. Only three models perform reasonably well: the empirical models derived from the data and an adaptation of the NCRP 129 model.

Our work will help to lower operating costs through improved scale prediction and add new revenue streams from sale of mineral byproducts extracted from geothermal fluids. Improving the economics and effectiveness of scale control programs and/or extraction systems in geothermal operations requires a coupled kinetic-thermodynamic model of silica behavior. Silica scale precipitation is a multi-step process, involving a nucleation-related induction period, aqueous polymerization, condensation of polymers to form colloids, and deposition onto a solid surface. Many chemical and physical variables influence the rates of these steps and their impacts must be quantified and predictable in order to optimally control silica behavior. To date, in laboratory studies, we have quantified the effects on silica polymerization of the following set of chemical variables: Na at 500 and 2000 ppm, pH values from 5 to 9, temperatures of 25 and 50 degrees C, and silica saturation values from 1.2 to 6 at initial dissolved silica concentrations of 600 ppm. Lowering pH both increases the induction time prior to polymerization and decreases the polymerization rate. We have successfully used a multiple regression model to predict polymerization rates from these variables. Geothermal fluids contain significant dissolved concentrations of potentially valuable mineral resources such as zinc, lithium, cesium and rubidium, but silica fouling interferes with traditional extraction methods. We are developing customized and new technologies to extract the silica as a commercial-grade commodity as well as the valuable metals. We are conducting field testing of some of these techniques at a Mammoth, CA geothermal plant using a reverse osmosis unit to concentrate the fluid, adding a commercial agglomerating agent to promote silica precipitation, and then removing the silica using a tangential flow ultrafilter. The particle size, surface area and trace impurities of the silica are characterized for comparison with commercial-grade silica products. We are also testing ion exchange resins and other functionalized materials to extract potentially economic concentrations of lithium, cesium, and rubidium that are enriched in the reverse osmosis concentrate.

Analysis of this data set reveal that several outcrops of these altered minerals exist in the area, and that one outcrop, roughly 1 square kilometer in area, shows abundant high temperature alteration. Structural analysis of the altered region using a Digital Elevation Model (DEM) suggests that this outcrop is bounded on all sides by a set of cross-cutting faults. This fault set lies within the Dixie Valley Fault system (Caskey et al. 1996). Both the intense alteration in this area and the presence of cross-cutting faults indicate a high probability of recent hot fluid escape.

In fractured samples, phase change (vaporization/condensation) can result in resistivity changes that are more than an order of magnitude greater than those measured in intact samples. These results suggest that electrical resistivity monitoring of geothermal reservoirs may provide a useful tool for remotely detecting the movement of water and steam within fractures, the development and evolution of fracture systems and the formation of steam caps. We measured the electrical resistivity of cores of welded tuff containing fractures of various geometries to investigate the resistivity contrast caused by active boiling and to determine the effects of variable fracture dimensions and surface area on water extraction from the matrix. We then used the Nonisothermal Unsaturated Flow and Transport model (NUFT) (Nitao, 1998) to simulate the propagation of boiling fronts through the samples. The simulated saturation profiles combined with previously reported measurements of resistivity-saturation curves allow us to estimate the evolution of the sample resistivity as the boiling front propagates into the rock matrix. These simulations provide qualitative agreement with experimental measurements suggesting that our modeling approach may be used to estimate resistivity changes induced by boiling in more complex systems.

S. Basin and Range with a focus on Dixie Meadows, Nevada AN - 881449919; 2011-065452 AB - This paper presents an overview of the work our collaboration is doing to increase the detailed mapped resource base for geothermal exploration in the Western US. We are imaging several large areas in the western US with high resolution airborne hyperspectral and satellite multispectral sensors. We have now entered the phase where the remote sensing techniques and tools we are developing are mature enough to be combined with other geothermal exploration techniques such as aeromagnetic, seismic, well logging and coring data. The imaging sensors and analysis techniques we have developed give us the ability to map visible faults, surface effluents, altered minerals, and subtle hidden faults. Large regions are being imaged at reasonable costs. The technique of geobotanical remote sensing for geothermal signatures is based on recent successes in mapping hidden faults, high temperature altered mineralization, clays, hot and cold springs and CO2 effluents the Long Valley Caldera and Mammoth Mountain in California. The areas that have been imaged include Mammoth Mountain and the Long Valley Caldera, Dixie Meadows NV, Fish Lake Valley NV, and Brady Hot Springs. Areas that are being imaged in the summer of 2003 are the south moat of the Long Valley Caldera, Mammoth Mountain western flanks, Mono Inyo chain north of Mammoth Mountain in CA, and the Humboldt Block in NV. This paper focuses on presenting the overview of the high-resolution airborne hyperspectral image acquisition that was done at Dixie Meadows NV in August 2002. This new imagery is currently being analyzed and combined with other field data by all of the authors on this paper. Results of their work up until June 23, 2003 are presented in other papers in the this volume, and their results up until the time of the conference will be presented in the remote sensing session on Tuesday morning.

AN - 72957025; 12526008 AB - The aim of this study was to determine the chemical structure of in vitro 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP)-modified oligodeoxynucleotides (ODNs) by exonuclease digestion and matrix-assisted laser desorption/ionization mass spectrometry. A single-stranded 11-mer ODN, 5'-d(CCATCGCTACC), was reacted with N-acetoxy-PhIP, resulting in the formation of one major and eight minor PhIP-ODN adducts. A 10 min treatment of the major and one minor PhIP-ODN adduct with a 3'-exonuclease, bovine intestinal mucosa phosphodiesterase (BIMP), and a 5'-exonuclease, bovine spleen phosphodiesterase, results in inhibition of the primary exonuclease activity at deoxyguanosine (dG) producing 5'-d(CCATCG(PhIP)) and 5'-d(G(PhIP)CTACC) product ions, respectively. Post-source decay (PSD) of these enzymatic end products identifies dG as the sole modification site in two 11-mer ODN-PhIP adducts. PSD of the minor PhIP-ODN adduct digestion end product, 5'-d(CCATCG(PhIP)), also reveals that the PhIP adducted guanine moiety is in an oxidized form. Prolonged treatment of the PhIP-ODN adducts at 37 degrees C with BIMP induces a non-specific, or endonuclease, enzymatic activity culminating in the formation of deoxyguanosine 5'-monophosphate-PhIP (5'-dGMP-PhIP). The PSD fragmentation pattern of the 5'-dGMP-PhIP [M + H](+) ion of the major adduct confirms PhIP binds to the C-8 position of dG. For the minor adduct, PSD results suggest that PhIP binds to the C-8 position of an oxidized guanine, supporting the hypothesis that this adduct arises from oxidative degradation, resulting in a spirobisguanidino structure.

AN - 72955845; 12517776 AB - The objective of this research was to determine whether Novantrone, Oncovin, Velban, and Prednisone (NOVP) combination chemotherapy for Hodgkin's disease increases the frequencies of the specific types of aneuploid sperm that might elevate the risk of fathering a child with one of the major clinical aneuploidy syndromes, i.e., Down (disomy 21 sperm), Edward (disomy 18 sperm), Turner (nullisomy sex sperm), XYY (disomy Y sperm), triple X (disomy X sperm), or Klinefelter (XY sperm). A four-chromosome multicolor sperm fluorescence in-situ hybridization assay that simultaneously evaluates chromosomes 18, 21, X, and Y was applied to semen provided by four healthy men and to repeated samples of eight Hodgkin's disease patients before treatment, 35-50 days after treatment to examine the effects of treatment on male meiotic cells, and 1-2 years after treatment to measure the persistence of damage. There were chromosome-specific variations in baseline frequencies and significant inductions of all of the detectable types of sperm aneuploidies: XY sperm (14-fold increase), disomy 18 (7-fold), nullisomy sex (3-fold), disomy 21 (3-fold), and disomy X and Y (approximately 2-fold each). Disomy 21 was about twice as frequent as disomy 18, and neither showed a preferential segregation with a sex chromosome. Extrapolating across the genome, approximately 18% of sperm carried a numerical abnormality after NOVP treatment of meiotic cells. Induced effects did not persist to 1-2 years after treatment, suggesting that persistent spermatogonial stem cells were not sensitive to NOVP. These findings establish the hypothesis that conception shortly after certain chemotherapies can transiently increase the risks of fathering aneuploid pregnancies that terminate during development or result in the birth of children with major human aneuploidy syndromes.

AN - 71475748; 14690798 AB - We conducted a study to evaluate dietary chemopreventive strategies to reduce genotoxic effects of the carcinogens 2-amino-1-methyl-6-phenyl-imidazo[4,5-b]pyridine (PhIP) and 2-amino-3-methylimidazo[4,5-f]quinoline (IQ). PhIP and IQ are heterocyclic amines (HCAs) that are found in cooked meat and may be risk factors for cancer. Typical chemoprevention studies have used carcinogen doses many thousand-fold higher than usual human daily intake. Therefore, we administered a low dose of [14C]PhIP and [3H]IQ and utilized accelerator mass spectrometry to quantify PhIP adducts in the liver, colon, prostate, and blood plasma and IQ adducts in the liver and blood plasma with high sensitivity. Diets supplemented with phenethylisothiocyanate (PEITC), genistein, chlorophyllin, or lycopene were evaluated for their ability to decrease adduct formation of [14C]PhIP and [3H]IQ in rats. We also examined the effect of treatments on the activity of the phase II detoxification enzymes glutathione S-transferase (GST), UDP-glucuronyltransferase (UGT), phenol sulfotransferase (SULT) and quinone reductase (QR). PEITC and chlorophyllin significantly decreased PhIP-DNA adduct levels in all tissues examined, which was reflected by similar changes in PhIP binding to albumin in the blood. In contrast, genistein and lycopene tended to increase PhIP adduct levels. The treatments did not significantly alter the level of IQ-DNA or -protein adducts in the liver. With the exception of lycopene, the treatments had some effect on the activity of one or more hepatic phase II detoxification enzymes. We conclude that PEITC and chlorophyllin are protective of PhIP-induced genotoxicity after a low exposure dose of carcinogen, possibly through modification of HCA metabolism.

Glass starting powders enriched in (super 18) O and (super 28) Si were mated to isotopically normal glass powders to form simple diffusion couples, and self-diffusion experiments were conducted in the piston cylinder device (1 and 2 GPa) and in the multianvil apparatus (3.5 and 4 GPa). Profiles of (super 18) O/ (super 16) O and (super 29,30) Si/ (super 28) Si were measured using secondary ion mass spectrometry. Self-diffusion coefficients for O (D(O)) are slightly greater than self-diffusion coefficients for Si (D(Si)) and are often the same within error. For example, D(O) = 4.20+ or -0.42X10 (super -11) m (super 2) /s and D(Si) = 3.65+ or -0.37X10 (super -11) m (super 2) /s at 1 GPa and 1662 degrees C. Activation energies for self-diffusion are 215+ or -13 kJ/mol for O and 227+ or -13 kJ/mol for Si. Activation volumes for self-diffusion are -2.1+ or -0.4 cm (super 3) /mol and -2.3+ or -0.4 cm (super 3) /mol for O and Si, respectively. The similar self-diffusion coefficients for Si and O, similar activation energies, and small, negative activation volumes are consistent with Si and O transport by a cooperative diffusion mechanism, most likely involving the formation and disassociation of a high-coordinated intermediate species. The small absolute magnitudes of the activation volumes imply that Di (sub 58) An (sub 42) liquid is close to a transition from negative to positive activation volume, and Adam-Gibbs theory suggests that this transition is linked to the existence of a critical fraction ( approximately 0.6) of bridging oxygen.

A comparison of (super 10) Be, (super 26) Al, and (super 41) Ca concentrations with calculated production rates from two different models indicates that the Gold Basin samples came from depths of about 10 cm to more than 150 cm in an object with a radius of 3-5 m. As was predicted by recent model calculations, the noble gases show a reversal of the (super 22) Ne/ (super 21) Ne ratio at very high shielding. The (super 21) Ne/ (super 10) Be and (super 21) Ne/ (super 26) Al ratios in most samples are constant and correspond to a 4pi exposure age of 18+ or -2 Myr. However, three Gold Basin samples show a 30-120% excess of (super 21) Ne implying that they were previously exposed close to the surface of the parent body, whereas the other samples were buried several meters deeper. Concentrations of neutron-capture (super 36) Ar in most samples are consistent with measured concentrations of neutron-capture (super 36) Cl and an exposure age of 18 Myr. Large excesses of neutron-capture (super 36) Ar were found in those samples with an excess of (super 21) Ne, providing additional evidence of a first-stage exposure on the parent body. The excess of spallation-produced (super 21) Ne and neutron-capture-produced (super 36) Ar in these samples indicate a first-stage exposure of 35-150 Myr on the parent body. The radiogenic (super 4) He and (super 40) Ar concentrations indicate a major impact on the parent body between 300 and 400 Myr ago, which must have preceded the impacts that brought the Gold Basin meteoroid to the surface of the parent body and then expelled it from the parent body 18 Myr ago.

The glacial geologic evidence and the CRN dating show that glaciers existed in this marginal region of Tibet during the latter part of the global Last Glacial Maximum and during the Lateglacial. These data suggest that temperatures were low enough and/or monsoon precipitation was sufficiently high to support one or more limited glacial advances between approximately 20 and 10 ka. Nevertheless glaciation was limited to glaciers of <10 km in length and the estimated ELA depression was approximately 800 m. These results confirm studies throughout other regions of Tibet and the Himalaya that show that glaciation was restricted during the latter part of the Last Glacial.

However both of these are topics of much debate, mainly due to the paucity of reliable, uninterrupted, regionally-representative proxy records back through the last glacial maximum (LGM). Reconstructions are often highly-localised and based on qualitative indicators of change. However material collected from the Amazon Fan allows us to examine an average signal of the whole of the Amazon Basin within a single sedimentary sequence. Here, we present data collected from ODP Site 942 and reveal that the Amazon Basin was forested yet relatively dry during the last glacial stage. Analysis of carbon isotopes on terrestrial biomarkers reveal that there has been relatively little shift in the C3:C4 ratio of the vegetation over the last 40 ka. Quantitative reconstructions of effective moisture based upon oxygen isotope analysis of planktonic foraminifera, suggest a significant reduction in the Amazon River outflow during both the LGM and last glacial-interglacial transition. We provide further evidence for glacial aridity through a quantified reconstruction of the fire history of the Amazon Basin, where fire-specific biomarkers are of coincident increased abundance throughout the more arid periods. We thereby refute the suggestion of encroaching savannah vegetation during glacial times, yet support the concept of a drier, cooler glacial Amazon Basin.

Pleistocene Lake levels are recorded in wave-cut terraces and lake-deposited tufas above the modern shoreline, but the Holocene climate record is preserved primarily in the sedimentary record. Pyramid Lake receives the majority of its input from the Truckee River, which heads in the Sierra Nevada. It is the only large closed-basin lake in the western Great Basin to have escaped desiccation during the Holocene. For this reason, it is an ideal site for reconstructing Holocene climate change. Three sediment cores spanning the last 7500 calendar years before present (cal yr BP) were analyzed for pollen at decadal to century-scale resolution. Dry periods were defined using the ratio of Chenopodiaceae (saltbush) pollen to Artemisia (sagebrush). This ratio suggests that the mid-Holocene (7500 - 6300 cal yr B.P.) was the warmest and driest portion of the record. Pyramid Lake was greatly reduced in size and the surface of Lake Tahoe was approximately 4 m below its modern elevation. Dry conditions persisted until approximately 5000 cal yr B.P. at which time there was a gradual but erratic increase in precipitation that continued as a generally wetter climate through 3500 cal yr B.P. A return to very dry conditions is seen between 2500 and 1800 years B.P. The last 1800 years have seen repeated wet-dry cycles, however none of the dry periods were as intense as those occurring during earlier periods. The record supports the evidence for prolonged droughts centered at approximately 800 and approximately 600 cal yr BP identified from submerged stumps at Mono Lake. The drought record reconstructed from fossil pollen correlates with the high-resolution record of multidecadal and multicentennial droughts identified in the oxygen isotope record from Pyramid Lake and compares favorably with other proxy records from the Great Basin. The timing of major shifts in climate also corresponds to the timing of rapid changes in drift-ice accumulation identified in the North Atlantic. These changes have been documented to coincide with changes in solar output. Our results imply that similar mechanisms may be responsible for Great Basin Holocene climate changes.

Precise Pliocene-Quaternary fan chronologies in arid regions are necessary for calculating strain rates and seismicity recurrence intervals. Soils geomorphology and cosmogenic 10Be in quartz on alluvium in the U.S. southwest (Providence Mtns., Fish Lake Valley, and Amargosa Valley) reveal that it is not always possible to attain high precision fan chronologies. Examination of alluvial fan sediments and surfaces from four lithologically distinct catchments in the Providence Mtns (eastern California) indicates that although fan aggradation is approximately synchronous around 75+ or -10 ka (QF3 fans), older and younger fans correlated along the same range front do not show this synchronicity. Instead of invoking geomorphological explanations of the exposure age disparities among correlative fans, we turned to the assumptions of the dating method. For the Mojave region, the 75-kyr aggradation event may be the most optimally suited for exposure dating. Older fans have significantly and variably disturbed surfaces (erosion, mixing, and burial also vary with elevation), so exposure ages (from surface boulders and subsurface and pavement pebbles) of correlated fans will vary. Large changes in bulk densities during pedogenesis also need to be considered. For younger fans, inheritance is the dominating control on the ages. In the Providence Mtns. and Amargosa Valley (western Nevada), modern wash sediment has as much as 70-kyr worth of inherited 10Be. Even with concentration-depth profiles using amalgamated pebble samples it is not possible to estimate this amount of inheritance with sufficient accuracy to correct a Holocene fan exposure age. The influence of inheritance diminishes with depositional age of a fan. Furthermore, when the option exists, we suggest choosing fans from rapidly eroding or previously glaciated catchments for dating, and correlating other fans along a range front with soils. Ages on a Holocene fan emanating from a glaciated catchment in Fish Lake Valley show lower standard deviations and are closer to radiocarbon ages than ages on a correlated radiocarbon-dated fan from a non-glaciated adjacent catchment.

Recently, the US Department of Energy approved the declassification of the NTS radionuclide inventory by principal geographic test centers. This permits unclassified publication of radionuclide totals for the Yucca Flat, Pahute Mesa--Area 19, Pahute Mesa--Area 20, Frenchman Flat, and Rainier Mesa/Shoshone Mountain testing locations. Activities are reported as of September 23, 1992, the date of the last underground nuclear test conducted at the NTS, and September 23, 2492, after 500 years of radioactive decay. The availability of these data affords an opportunity for the analysis of the radiologic source term within the boundaries of local hydrogeologic units and provides insight to where radionuclides are sited relative to potential exposure pathways.

Based on previous detailed dose assessments for Bikini, Enewetak, Rongelap, and Utirik Atolls over a period of 28 years, cesium-137 ( (super 137) Cs) at Bikini Atoll contributes about 85-89% of the total estimated dose through the terrestrial food chain as a result of uptake of (super 137) Cs by food crops. The estimated integral 30, 50, and 70-year doses were based on the radiological decay of (super 137) Cs (30-year half-life) and other radionuclides. However, there is a continuing inventory of (super 137) Cs and (super 90) Sr in the fresh water portion of the groundwater at all contaminated atolls even though the turnover rate of the fresh groundwater is about 5 years. This is evidence that a portion of the soluble fraction of (super 137) Cs and (super 90) Sr inventory in the soil is lost by transport to groundwater when rainfall is heavy enough to cause recharge of the lens, resulting in loss of (super 137) Cs from the soil column and root zone of the plants. This loss is in addition to that caused by radioactive decay. The effective rate of loss was determined by two methods: (1) indirectly, from time-dependent studies of the (super 137) Cs concentration in leaves of Pisonia grandis, Guettarda specosia, Tournefortia argentea (also called Messerschmidia), Scaevola taccada, and fruit from Pandanus and coconut trees (Cocos nucifera L.), and (2) more directly, by evaluating the (super 137) Cs/ (super 90) Sr ratios at Bikini Atoll. The mean (and its lower and upper 95% confidence limits) for effective half-life and for environmental-loss half-life (ELH) based on all the trees studied on Rongelap, Bikini, and Enewetak Atolls are 8.5 years (8.0 years, 9.8 years), and 12 years (11 years, 15 years), respectively. The ELH based on the (super 137) Cs/ (super 90) Sr ratios in soil in 1987 relative to the (super 137) Cs/ (super 90) Sr ratios at the time of deposition in 1954 is less than 17 years. The magnitude of the decrease below 17 years depends on the ELH for (super 90) Sr that is currently unknown, but some loss of (super 90) Sr does occur along with (super 137) Cs. If the 15-year upper 95% confidence limit on ELH (corresponding to an effective half-life of 9.8 years) is incorporated into dose calculations projected over periods of 30, 50, or 70 years, then corresponding integral doses are 58, 46 and 41%, respectively, of those previously calculated based solely on radiological decay of (super 137) Cs.

In this context, the finding of remains from five individuals dated to the 9th millenium BP on the re-excavations at Bano Nuevo Cave (Andean Central Patagonia, Chile) is particularly interesting. They may not appear excessively old, but several radiocarbon dates (two of them done through AMS directly on the bone of one of the individuals) place them among the very few well-dated early human skeletons throughout the Americas. The small sample size militates against any interpretation of biological affiliation (to say nothing of population movements) and we can only affirm that these people belonged to a generalized "mongoloid stock", different from historically known Patagonian populations. After a brief presentation of the skeletal evidence and the bone dating methods, we evaluate the relevance of this context with respect to the sparse osteological record of humans in the Americas on the Pleistocene/Holocene transition.

The study makes use of data recorded during nuclear explosions at the Nevada Test Site, at several stations across the Las Vegas basin. Data from two stations located near rock on opposite edges of the basin were deconvolved for use as input to project surface motions at two deep-basin sites. The soil models for the deep basin sites were constructed using relevant geotechnical borehole information and lithologic well logs. Shear wave velocity profiles for individual sites were developed from a combination of seismic test results including downhole, crosshole, SASW, ReMi and refraction. Small-strain damping and strain-dependent dynamic soil properties were inferred from published literature. Appropriate depth to halfspace was selected according to the criterion that projected peak ground acceleration should match the measured value. Site-specific amplification of the two soil sites, subjected to the two different base motions, was calculated. Comparisons of projected ground motions with measured motions showed that alluvial deposits are significant contributors to small-strain seismic response of the Las Vegas basin in the frequency band 0.8 to 15 Hz. The one-dimensional model captured important ground motion features such as peak ground acceleration and maximum spectral acceleration. Appropriate depth to model halfspace is considerably less than the depth to bedrock. High-velocity cemented inclusions should be explicitly accounted for in the soil profile.

The goal is to identify and locate rockfall events remotely using automated data collecting and processing techniques. We will install seismometers on the ground surface, generate seismic energy to simulate rockfall in underground space beneath the array, and interpret the surface response to discriminate and locate the event. Data will be analyzed using matched-field processing, a generalized beamforming method for localizing discrete signals. Software is being developed to facilitate the processing. To date, a three-component sub-array has been installed and successfully tested.

The targeted application for this research is ensuring the long-term stability of the underground openings of the proposed repository for high-level nuclear waste at Yucca Mountain. To this end, we are installing six seismometers on the ground surface above existing underground passages. The seismic array, including seismometers, data acquisition system, and preliminary data visualization and reduction, will be tested using simulated rockfall. Data acquired during the tests will be analyzed using concepts of matched-field waveform processing to explore the feasibility of the passive seismic monitoring concept to locate rockfall events. To date, a three-component sub-array has been installed and a preliminary test has been performed. In the preliminary test, seismic energy was supplied by hammering on rock bolts in the Yucca Mountain Exploratory Studies Facility (ESF) alcoves and train operation within the ESF. Data were acquired underground and with the surface sub-array. The results of the preliminary test indicate that the equipment is working properly and that seismic signals produced within the ESF can be recorded on the surface. Simulated rockfall tests, currently in preparation stages, will be performed using dropped weights.

Individual analyses ranged from 18,090-18,245 yr BP with reported errors between 30-50 yr. The weighted average fraction modern (FM) of these 28 measurements is 0.10378 + or - 0.00008 (which equates to 18,199 + or - 8 yr BP) and the measurements show a 1 standard deviation scatter of 0.00044 (+ or -35 yr). The fractional error of these results indicates reproducibility of individual measurements at the 4 per mil (1sigma ) level, which is consistent with the quoted counting-statistics-based errors. Laboratories engaged in the determination of (super 14) C results at reasonably high precision should consider taking advantage of the TIRI and FIRI sample materials in the role of process standards. Additional suites of high-precision data are necessary to refine the accuracy of these sample materials.

EQ3/6 was used to model alteration scenarios with available kinetic data. Calculation predictions were tested in four experiments to determine if carbonate minerals would form under specific laboratory conditions as predicted by calculation. Each experiment used Dickson-type rocking gold bag autoclaves running for 3 to 5 months with 75-100 Am-sized An (sub 60) plagioclase grains at 150 degrees C and pressures of 100 bars. Variables include initial CO (sub 2) fugacity (from 0.15 to 70 bars), supporting electrolyte, alkalinity and pH. Calculations suggest that enough alkalinity could be produced by reaction with plagioclase to reach saturation with respect to carbonate minerals; higher fCO (sub 2) conditions led to saturation with respect to dawsonite [NaAlCO (sub 3) (OH) (sub 2) ] at pH 3.6, and lower fCO (sub 2) conditions led to saturation with respect to calcite at pH 5.9 and at pH 6.9 (with and without 0.01 m starting alkalinity, respectively). The reacted plagioclase grains were analyzed by petrography, XRD, SEM/EDS, CO (sub 2) analysis, and AFM. Petrography and powder XRD did not reveal any carbonate precipitate. SEM and AFM images showed no evidence for secondary carbonate mineral precipitation, and analysis of the grains for CO (sub 2) exsolution after acidification revealed no carbonate source. The plagioclase dissolution rates were highest initially then progressively slowed as the solutions became more saturated with respect to the feldspar. Because of the complex initial aqueous conditions, dissolution congruency could not be precisely established. This work highlights the need for longer-term field and laboratory experiments to test geochemical aspects of CO (sub 2) sequestration, as well as for evolution of codes to better account for dissolution/growth inhibition, nucleation, and other processes.

AN - 51692715; 2005-052809 AB - Although CO (sub 2) reservoirs are commonly referenced as natural analogs to engineered geologic storage sites, there are important distinctions between these settings that may preclude their direct correlation. Most importantly, natural CO (sub 2) accumulations were established over geologic time frames, while CO (sub 2) injection at potential sequestration sites represents a dramatically telescoped and therefore very different thermal, hydrological, geochemical, and geomechanical perturbation of the reservoir/cap rock system. This distinction raises two intriguing possibilities that warrant quantitative investigation. First, the currently secure cap rock of a given natural CO (sub 2) accumulation may have evolved into such as a function of geochemical alteration that attended some degree of initial CO (sub 2) migration through it. Second, whether or not such evolution took place, this same cap rock may be incapable of providing an effective hydrodynamic seal in the context of an engineered injection. There are two corresponding fundamental questions. First, what is the evolution of cap-rock integrity during formation of natural CO (sub 2) reservoirs? Second, will such evolution be similar or appreciably different in engineered storage sites; i.e., what is its dependence on the rate, focality, and duration of CO (sub 2) influx? These questions--upon which strict validity of the natural-analog concept hinges--can be addressed using the reactive transport modeling approach. In this study, we will conduct and compare reactive transport simulations of a well-characterized CO (sub 2) reservoir under both natural and hypothetical anthropogenic "filling" modes. Our results will reveal the dependence of long-term cap-rock integrity on filling history, and thereby shed quantitative light on appropriateness of the natural-analog concept.

Absolute permeability is obtained from lattice-Boltzmann viscous flow simulation in the digital pore space, represented by zeros for the pores and ones for the mineral phase. The numerical results closely match measured permeability in the sample. We numerically alter the original digital sample by (a) depositing cement on the grain surface and (b) inserting small "silt" particles into the pore space. By calculating the permeability of the altered sandstone, we obtain permeability-porosity trends that differ depending on the diagenetic alteration process. We explore obtaining accurate permeability estimates from 2-D images. In this approach, the 3-D digital pore space realizations are generated from digitized 2-D images via statistical indicator simulation. We produce digital 2-D images from the original 3-D digital sample by slicing it in the computer. The 2-D porosity of the slices, on average, is the same as the measured 3-D porosity. However, the statistical spread around the average value is noticeable. It is remarkable that the calculated permeability of the statistically reconstructed 3-D realizations matches, on average, the calculated permeability of the original digital sample and also the measured permeability. Finally, we apply diagenetic alterations to 2-D slices, statistically reconstruct the corresponding 3-D samples, and calculate their permeability. The results indicate that in clastic sediments, absolute permeability can be accurately estimated from 2-D sections.

The results show that (super 10) Be concentrations in this area are mainly controlled by surface biological productivity, particle remineralization, and the degree of mixing with the Yangtze River and the Kuroshio waters. During the sampling periods (summer and autumn), the East China Sea was well stratified. Generally, the (super 10) Be water depth profiles can be divided into three layers: the surface mixed layer, the particulate (super 10) Be regeneration layer, and the bottom layer. Surface water (super 10) Be concentrations increase gradually towards the Kuroshio and increase sharply at the edge of the Kuroshio Current. Vertical distributions of (super 10) Be show that in the summer (super 10) Be is enriched in the bottom water near the Yangtze River estuary and the bottom water in the middle of the continental shelf. The two enriched areas are separated, probably by an intrusion of the Continental Coastal Water. In the autumn, (super 10) Be bottom enrichment only occurred in the western part of the East China Sea. This phenomenon is consistent with the seasonal circulation pattern change of currents induced by monsoon winds. The influence on (super 10) Be by the Kuroshio branch intrusion in the southern East China Sea northeast of Taiwan may be more significant than the Kuroshio main flow. Simple box model results indicate that (super 10) Be input from the Kuroshio Current is more important than Yangtze River input and atmospheric precipitation. About 81% of (super 10) Be input to the East China Sea is scavenged into the sediments and 19% of (super 10) Be flows out of the East China Sea by currents and water exchange. The (super 10) Be sedimentation flux in the East China Sea is nearly five times of the average global (super 10) Be production rate, suggesting that the East China Sea is an important sink for (super 10) Be.

(super 26) Al and (super 10) Be data acquired from numerous transects across distal, medial and proximal landscape positions suggest that sediment supplied to the Chemehuevi Mountain piedmont is mainly from the mountain source basins (4 X 10 (super 4) kg km (super -2) y (super -1) ) and the proximal bedrock pediment (3.3 X 10 (super 4) kg km (super -2) y (super -1) ). Relatively little of the sediment currently at the ground surface across the piedmont appears to be derived from erosion of incised alluvium and from the channel bed (0.2 X 10 (super 4) kg km (super -2) y (super -1) and 0.3 X 10 (super 4) kg km (super -2) y (super -1) , respectively). Nuclide activities of sediment collected from active channels increase steadily down the 12 km - long piedmont. Based on the sediment budget, the down piedmont increase in nuclide activity, and the thickness of sediment in active transport ( approximately 32 cm to approximately 17 cm from the rangefront to the distal piedmont, respectively) we modeled average sediment speeds of 8 to 39 cm y (super -1) . Nuclide analyses and soil development of two soil pits, located approximately 6 km and approximately 12 km from the rangefront, suggest complex histories of sediment deposition, surface erosion, and surface stability. Nuclide analyses of sediment from the pit 12 km from the rangefront suggests sediment deposition rates of 20 to 37 mm ky (super -1) until approximately 8,000 years ago when deposition was replaced by sediment transport. This interpretation is consistent with the observed soil characteristics that indicate that late Holocene sediments overlie early Holocene sediments at this pit. Soil development and nuclide analyses of sediment from the pit approximately 6 km from the rangefront suggests a complex history of sediment deposition (18 mm ky (super -1) ), surface erosion (truncated soil horizons), and surface stability (buried soils, as well as varnished pavement at the current ground surface) over the past approximately 70,000 years. By using cosmogenic nuclides we provide a new window into understanding the behavior of these enigmatic features over large spatial- and long temporal-scales.

Alluvial fans, pediment surfaces, shorelines and a thick succession of sediments within the basin coupled with moraines and associated landforms in the adjacent high mountains record a complex history of Late Quaternary paleoenvironmental change and landscape evolution. The Qaidam basin, one of the largest hyper-arid intermontane basins on Earth, is a natural laboratory to examine the nature of intermontane basin evolution within a continent-continent collision zone. Furthermore, it provides an opportunity to relate the timing of landscape evolution in a hyper-arid environment to climatic change and associated glacial and hydrological changes. Critical sites along the southern and northwestern margins of the Qaidam Basin provide evidence of a strong link between times of climatic amelioration, deglaciation, lake desiccation and alluvial fan sedimentation. From these observations we believe that the major landscape changes took place very rapidly over short intervals of time during periods of climatic instability. To test this hypothesis, we have undertaken remote sensing, field mapping, geomorphological and sedimentological analysis, and numerical dating of Late Quaternary landforms within the Qiadam basin. In particular, we have undertaken an extensive program of cosmogenic radionuclide (CRN) surface exposure dating to define the ages of Late Quaternary landforms. This is allowing us to test our hypothesis that the timing of formation of landforms is synchronous with times of climatic instability.

It is therefore essential to have a standard radiocarbon calibration datasets for such intercomparisons to be valid, rather than using an ad hoc mixture of (super 14) C datasets without proper consideration of potential errors in timescale or carbon reservoir corrections. The IntCal04 Radiocarbon calibration/Comparison Working Group has put together a set of criteria for assuring datasets are sufficiently robust in both the cal ages and the radiocarbon ages and that the uncertainties are quantified (Reimer et al., 2002). Refinements and additions to IntCal98 should result in a calibration dataset back to ca. 30 ka BP, which will be presented for ratification at the 19th International Radiocarbon Conference in Wellington, New Zealand. In addition, the IntCal04 Group is working towards a recommendation for comparing (super 14) C based chronologies beyond 30 ka BP where few absolutely dated records exist and there is wide discrepancy among them. We will highlight the differences between IntCal98 and the proposed IntCal04 dataset with example radiocarbon calibrations for some important climatic events.

Radiocarbon ages spanning the last 11,900 years are calibrated to calendar years by making radiocarbon age determinations on tree rings of a known age. Over this time interval, fluctuations in the atmospheric 14C were largely produced by changes in the solar magnetic field. For the age interval between 12,000 years and 50,000 yrs BP, radiocarbon ages are calibrated by less accurate methods, such as varved sediments, rapidly accumulating marine sediments, 230Th/234U/238U dating of spelothems, and 230Th/234U/238U dating of corals. In addition to solar contributions prevalent in the Holocene, carbon cycle variations contribute to atmospheric 14C fluctuations in the pre-Holocene. Combining published radiocarbon calibration data greater than 12,000 yrs. BP results in an unusable calibration data set because offsets and contradictions are the norm among these various data sets. Our contributions to the international radiocarbon calibration effort are the high precision 230Th/234U/238U and 14C analyses of a suite of unusually high quality coral samples cored from drowned reefs offshore several islands in the tropical Atlantic and Pacific oceans. We have overlapped and extended the tree-ring radiocarbon calibration from 11,000 to 50,000 yrs. BP in enough detail to be used as a stand-alone radiocarbon calibration of the highest quality. We have measured a radiocarbon anomaly produced during the Laschamp geomagnetic excursion that confirms the K/Ar date on the Laschamp flow at 47.4 + or - 1.9 kyrs BP reported by Hall and York (1978). This age is between 15% and 24% older than recent Laschamp age estimates based on ice core and marine core chronologies. The age offset between uncalibrated radiocarbon years and 230Th/234U/238U calendar years exceeds 9200 years during the Laschamp excursion. The radioactive decay of the Laschamp 14C anomaly, compounded by several smaller anomalies, results in the long-term convergence of radiocarbon and calendar years. Conveniently, the large 14C production anomaly produced during the Laschamp excursion "spiked" the carbon reservoirs with sufficient radiocarbon to effectively extend the useful range of radiocarbon dating to eight half-lives.

Glaciation in this region is controlled by two major climatic systems: the mid-latitude westerlies and the South Asian monsoon. In addition, significant interannual climatic variability in the region is associated with El Nino-Southern Oscillation. Furthermore, glaciation is strongly influenced by topographic constraints. Yet despite the regional and global importance of glaciation in High Asia, the dynamics, extent and timing of glaciation in this region are poorly understood and defined. To test the relative importance of the different climatic systems and topographic constraints on glaciation, as well as the associated hydrological changes, we have been systematically examining the glacial and associated geology throughout the region, and dating landforms and sediments using cosmogenic radionuclide (CRN) surface exposure and optically stimulated luminescence (OSL) techniques. To date, we have undertaken detailed studies in the following mountain regions: Chitral, Swat, Nanga Parbat, Hunza Valley, Lahul, Ladakh, Zanskar, Garhwal, Nanda Devi, Langtang, Khumbu, Gonga Shan, Gangdise, Nyainqentangulha, Tangula, Kunlun, Nianbaoyeze, Anyemaqen, La Ji and Qilian Shan. This work has included detailed mapping, together with nearly equal 1000 numerical dates on moraines and associated landforms that define the extent and timing of glaciation. These data indicate a strong monsoonal influence on glaciation, synchroneity of glaciation and topographic constraints on extent of glaciation throughout Tibet and the bordering mountains. Glacial oscillations are shown to correlate with changes in the hydrological system and sediment flux that, in turn, largely control landscape changes.

New evidence presented in this study is consistent with Holocene ages for these groundwaters. Isotopic, chemical, and hydrogeologic data suggest the Death Valley groundwaters are transported southward up to 300 km through regional carbonate aquifers of the Railroad Valley flow system. Groundwaters in the northern part of the flow system have delta (super 18) O values nearly identical to recharge derived from winter precipitation in central Nevada. Isotopic analyses of snow cores revealed kinetic isotope enrichments in the snowpack prior to melting may account for observed isotopic enrichments in groundwaters relative to the global meteoric water line. Geographically consistent trends in delta (super 18) O values, water chemistry, and carbon isotopes are observed along the entire 300 km regional flow path. Dissolved inorganic carbon quickly reacts with the carbonate aquifer due to elevated subsurface temperatures and cation exchange processes, yielding (super 14) C values <10 pmc within 30 km of the northernmost recharge area. Groundwater mixing along the flow path maintains uniformly low nonzero (super 14) C values. The complexities of the flow system preclude the application of (super 14) C age correction models. Hydrologic mass balance calculations imply turnover rates are too high to store significant amounts of pluvial recharge in the regional carbonate aquifer. Closed alluvial basins provide more favorable geologic environments for remnant accumulations of Pleistocene groundwater, as indicated by rare, isolated pockets of unusually low delta (super 18) O groundwater.

We describe an algorithm for simulating radiation diffusion on such a mesh, coupled to multi- fluid gasdynamics. Conservation laws are enforced by using locally conservative difference schemes along with explicit synchronization operations between different levels of refinement. In unsteady calculations each refinement level is advanced at its own optimal timestep. Particular attention is given to the appropriate coupling between the fluid energy and the radiation field, the behavior of the discretization at sharp interfaces, and the form of synchronization between levels required for energy conservation in the diffusion process. Two- and three-dimensional examples are presented, including parallel calculations performed on an IBM SP-2.

In the present study, we have made a matched repair-competent cell line by mutagenizing 5P3NAT2 cells with ethyl methanesulfonate and selecting for resistance to cytotoxicity by 2-amino-3-methylimidazo[4,5-f]quinoline (IQ). In the differential cytotoxicity (DC) assay, 4 out of 15 clones showed no cytotoxic effect with IQ at the highest dose (30 mu g/ml) tested, in contrast to repair-deficient 5P3NAT2 cells, which showed similar to 100% cytotoxicity at 0.3 mu g/ml. Subsequently, these IQ-resistant clones were examined for resistance to killing by UV irradiation. All four IQ-resistant clones, which show resistance to UV similar to that of repair-proficient AA8 cells, still express both the CYP1A2 and N-acetyltransferase genes. Sequence analysis of CXPD cDNA from the 5P3NAT2R9 clone revealed an A:T arrow right G:C reversion event at the site of the UV5 mutation. This base change results in reversion of the codon 116 tyrosine in UV5 cells back to the original cysteine in AA8 cells, thereby restoring wild-type CXPD activity and repair function. In contrast to 5P3NAT2 cells, the repair-proficient 5P3NAT2R9 revertant cell line shows little IQ-induced cell killing, and dramatically lower levels of induced mutation at the adenine phosphoribosyltransferase (Aprt) gene locus over the range of 2-40 mu g/ml IQ. This matched pair of repair-proficient/deficient cell lines can provide insight not only into the genotoxicity of heterocyclic amine dietary carcinogens such as IQ and PhIP, but also into the effects of nucleotide excision repair on the ultimate mutagenicity of these compounds.

As the success of this emerging form of radiation therapy grows, accurate treatment planning and radiation dose simulations are likely to become increasingly important. To address this need, we have initiated the development of a new, Monte Carlo transport-based treatment planning system for molecular targeted radiation therapy as part of the MINERVA system. The goal of the MINERVA dose calculation system is to provide 3-D Monte Carlo simulation-based dosimetry for radiation therapy, focusing on experimental and emerging applications. For molecular targeted radionuclide therapy applications, MINERVA calculates patient-specific radiation dose estimates using computed tomography to describe the patient anatomy, combined with a user-defined 3-D radiation source. This paper describes the validation of the 3-D Monte Carlo transport methods to be used in MINERVA for molecular targeted radionuclide dosimetry. It reports comparisons of MINERVA dose simulations with published absorbed fraction data for distributed, monoenergetic photon and electron sources, and for radioisotope photon emission. MINERVA simulations are generally within 2% of EGS4 results and 10% of MCNP results, but differ by up to 40% from the recommendations given in MIRD Pamphlets 3 and 8 for identical medium composition and density. For several representative source and target organs in the abdomen and thorax, specific absorbed fractions calculated with the MINERVA system are generally within 5% of those published in the revised MIRD Pamphlet 5 for 100 keV photons. However, results differ by up to 23% for the adrenal glands, the smallest of our target organs. Finally, we show examples of Monte Carlo simulations in a patient-like geometry for a source of uniform activity located in the kidney.

To gain insight into the genomic alterations associated with PhIP-induced mammary gland carcinogenesis, we used comparative genomic hybridization (CGH) to examine chromosomal abnormalities in rat mammary carcinomas induced by PhIP, and for comparison, by DMBA (7, 12-dimethylbenz[a]anthracene), a potent experimental mammary carcinogen. There was a consistent and characteristic pattern of chromosome-region loss in PhIP-induced carcinomas that clearly distinguished them from carcinomas induced by DMBA.

An in vitro transposition reaction is used to introduce a well-characterized replicon and selectable marker into purified plasmids, which are then used to transform E. coli. The approach was demonstrated using a small 3.4-kb archaeal plasmid and a large 60-kb uncharacterized plasmid from a Gram-negative bacterium. Replicon function in E. coli was tested for each plasmid, and direct sequencing of the large plasmid revealed similarity to restriction-modification systems.

AN - 72866669; 12634135 AB - Full toxicologic profiles of chemical mixtures, including dose-response extrapolations to realistic exposures, is a prohibitive analytical problem, even for a restricted class of chemicals. We present an approach to probing in vivo interactions of pesticide mixtures at relevant low doses using a monitor compound to report the response of biochemical pathways shared by mixture components. We use accelerator mass spectrometry (AMS) to quantify [14C]-diisopropylfluorophosphate as a tracer at attomole levels with 1-5% precision after coexposures to parathion (PTN), permethrin (PER), and pyridostigmine bromide separately and in conjunction. Pyridostigmine shows an overall protective effect against tracer binding in plasma, red blood cells, muscle, and brain that is not explained as competitive protein binding. PTN and PER induce a significant 25-30% increase in the amount of tracer reaching the brain with or without pyridostigmine. The sensitivity of AMS for isotope-labeled tracer compounds can be used to probe the physiologic responses of specific biochemical pathways to multiple compound exposures.

The contents of light noble gases (He, Ne, and Ar) and long-lived radionuclides ( (super 10) Be, (super 26) Al, (super 36) Cl, and (super 53) Mn), produced by nuclear reactions with cosmic rays, were measured in the separated metal and olivine phases from numerous samples representing a wide range of shielding conditions in the meteoroid. The distribution of cosmogenic nuclide concentrations in the metal follows patterns similar to that observed in large iron meteorites. Shielding effects were estimated from the relative proportions of low-and high-energy reaction products. The production rates varied, from surface to interior, by a factor of more than several hundred. The (super 36) Cl- (super 36) Ar cosmic-ray exposure age of Brenham is 156+ or -8 Myr. This determination is based on a multiple nuclide approach that utilizes cosmogenic nuclide pairs. This approach not only yields a "shielding independent" exposure age but also demonstrates that the production of cosmogenic nuclides occurred in a single stage. The depth profiles of (super 10) Be in the stone phase and (super 53) Mn in the metal phase are shown superimposed on corresponding profiles from the Apollo 15 long drill core. Surprisingly low abundances of lithophile elements, such as K, U, and Th, provided a unique opportunity to examine the production systematics of those nuclides whose inventories typically have significant contributions from non-cosmogenic sources, particularly radiogenic contributions. The U and Th contents of the olivine samples are extremely low, allowing detection of cosmogenic (super 4) He production from oxygen, magnesium, silicon, and iron.

The scatter in earthquake population discriminant measurements for fixed propagation paths is statistically analyzed to assess the spatial and frequency-dependent contributions from source radiation pattern and source depth variations along with variable near-source scattering. This is useful because procedures for reducing the variance caused by propagation effects must be constrained by knowledge of the intrinsic scatter resulting from independent source effects, for which corrections are not available without a priori knowledge of the source type and depth. Broadband waveforms for earthquakes near the Nevada Test Site (NTS) and in southern California recorded at stations of the Livermore NTS Network (LNN), the Caltech TERRA scope Network, and the Berkeley Digital Seismic Network (BDSN) are used to obtain Pg/Lg and Pn/Lg measurements and to assess source depth and mechanism contributions to measurement variance. Pn/Lg and Pg/Lg spectral amplitude ratios for several frequency bands between 0.5 and 10 Hz from vertical velocity waveforms are computed for a total of 18 tightly located clusters of earthquakes. For each cluster, we examine the correlations between observed Pn/Lg and Pg/Lg ratios and estimated source depths or predictions based on previously determined source mechanisms. Focal mechanism predictions do not match the observations well, likely due to strong near-source scattering and directivity effects that overwhelm the point-source radiation pattern. However, the data do show significant scatter even for sources only a few kilometers apart. Source depth produces some coherent trends, which can be emphasized by averaging results from multiple stations. These trends vary from region to region, presumably due to specific local crustal layering, but most of the variance is not deterministically predictable and appears to arise from strong variations in near-source scattering. Variance estimates for logarithmic amplitude ratios normalized by mean amplitude ratios vary from 0.01 to 0.05 for different phase pairs. Frequency-dependent variations of the mean, variance, minimum, and maximum amplitude ratio parameters show strong distance dependence out to about 300 km and then appear to become independent of event-station distance. These variance parameters appear to be suitable for use in spatial interpolations of observed P/S-type ratios for a specific unidentified event path, as needed for nuclear test monitoring.

Sea ice is the first variable to change during the last deglaciation, followed by nutrient proxies and sea surface temperature. The comparison of the marine records to Antarctic ice CO (sub 2) variation depends on the age model as (super 14) C determinations cannot be obtained for the time interval of 29.5-14.5 ka. Our diatom-based sea ice record is in phase with the sodium record of the Vostok ice core. If gas exchange played a major role in determining glacial to interglacial CO (sub 2) variations, the main cause of atmospheric pCO2 change must be sought elsewhere, rather than in the Southern Ocean.

We combined information on the molecular bonding of metals in solids from X-ray absorption spectroscopy (XAS) with thermodynamic and kinetic driving forces obtained from dissolved metal concentrations to deduce the dominant reactions under reduced and oxidized conditions. We evaluated the in situ geochemistry of metals (cadmium, chromium, iron, lead, manganese and zinc) as a function of sediment depth (to 100 cm) from a 60 year record of contamination at the Alameda Naval Air Station, California. Results from XAS and thermodynamic modeling of porewaters show that cadmium and most of the zinc form stable sulfide phases, and that lead and chromium are associated with stable carbonate, phosphate, phyllosilicate, or oxide minerals. Therefore, there is minimal risk associated with the release of these trace metals from the deeper sediments contaminated prior to the Clean Water Act (1975) as long as reducing conditions are maintained. Increased concentrations of dissolved metals with depth were indicative of the formation of metal HS super(-) complexes. The sediments also contain zinc, chromium, and manganese associated with detrital iron-rich phyllosilicates and/or oxides. These phases are recalcitrant at near-neutral pH and do not undergo reductive dissolution within the 60 year depositional history of sediments at this site. The fate of these metals during dredging was evaluated by comparing in situ geochemistry with that of sediments oxidized by seawater in laboratory experiments. Cadmium and zinc pose the greatest hazard from dredging because their sulfides were highly reactive in seawater. However, their dissolved concentrations under oxic conditions were limited eventually by sorption to or co-precipitation with an iron (oxy)hydroxide. About 50% of the reacted CdS and 80% of the reacted ZnS were bonded to an oxide-substrate at the end of the 90-day oxidation experiment. Lead and chromium pose a minimal hazard from dredging because they are bonded to relatively insoluble carbonate, phosphate, phyllosilicate, or oxide minerals that are stable in seawater. These results point out the specific chemical behavior of individual metals in estuarine sediments, and the need for direct confirmation of metal speciation in order to constrain predictive models that realistically assess the fate of metals in urban harbors and coastal sediments.

Polydimethylsiloxane (PDMS) is cast into an acrylic mold frame with suspended elements that are removed after curing to form chip cavities, inlet and outlet ports, microchannels, and reservoirs. The packaging approach enables the integration of off-the-shelf components such as pumps and valves with glass microfluidic devices, electronic chips, sample reservoirs, and flow channels. A particle pre-concentration module with a glass capture chip and integrated micropump is shown as an example. A pneumatically driven microfluidic pumping module is also shown. Custom microfluidic interconnects for interfacing to micro-scale fluidic systems are presented. The connectors are capable of withstanding more than 1000 psi and allow microdevices to be rapidly connected to macroscopic devices and systems, without the use of tools.

However, given the space limitations and the negative public perception of large volumes of waste, there is a growing international motivation to develop a fusion waste management system that maximizes the amount of material that can be cleared or recycled. In this work, we present an updated assessment of the waste management options for the HYLIFE-II inertial fusion energy (IFE) power plant, using the concept of clearance index (CI) for radioactive waste disposal. With that purpose, we have performed a detailed neutronics analysis of the HYLIFE-II design, using the TART and ACAB computer codes for neutron transport and activation, respectively. Whereas the traditional version of ACAB only provided the user with the gamma contact dose rate for recycling assessments and WDR as an index for waste disposal considerations, here we have modified the code to calculate CIs using the current international atomic energy agency (IAEA) clearance limits for radiological waste disposal. The results from the analysis are used to perform an assessment of the waste management options for the HYLIFE-II IFE design.

AN - 72681684; 12427531 AB - We review the genes and proteins related to the homologous recombinational repair (HRR) pathway that are implicated in cancer through either genetic disorders that predispose to cancer through chromosome instability or the occurrence of somatic mutations that contribute to carcinogenesis. Ataxia telangiectasia (AT), Nijmegen breakage syndrome (NBS), and an ataxia-like disorder (ATLD), are chromosome instability disorders that are defective in the ataxia telangiectasia mutated (ATM), NBS, and Mre11 genes, respectively. These genes are critical in maintaining cellular resistance to ionizing radiation (IR), which kills largely by the production of double-strand breaks (DSBs). Bloom syndrome involves a defect in the BLM helicase, which seems to play a role in restarting DNA replication forks that are blocked at lesions, thereby promoting chromosome stability. The Werner syndrome gene (WRN) helicase, another member of the RecQ family like BLM, has very recently been found to help mediate homologous recombination. Fanconi anemia (FA) is a genetically complex chromosomal instability disorder involving seven or more genes, one of which is BRCA2. FA may be at least partially caused by the aberrant production of reactive oxidative species. The breast cancer-associated BRCA1 and BRCA2 proteins are strongly implicated in HRR; BRCA2 associates with Rad51 and appears to regulate its activity. We discuss in detail the phenotypes of the various mutant cell lines and the signaling pathways mediated by the ATM kinase. ATM's phosphorylation targets can be grouped into oxidative stress-mediated transcriptional changes, cell cycle checkpoints, and recombinational repair. We present the DNA damage response pathways by using the DSB as the prototype lesion, whose incorrect repair can initiate and augment karyotypic abnormalities.

Another 10 age determinations from the younger Buzzards Bay moraine near Woods Hole, MA, indicate that this moraine complex was formed 18,800+ or -400 yr ago. These ages correlate approximately with the terminations of cooling cycles recorded in Greenland ice cores and coeval ice-rafting events, suggesting that the marginal position of this sector of the ice sheet was tightly coupled to North Atlantic climate during the last glacial maximum.

In this paper, we address the impact of these climate stabilization schemes on terrestrial biosphere using equilibrium simulations from a coupled atmosphere-terrestrial biosphere model. Climate stabilization would tend to limit changes in vegetation distribution brought on by climate change, but would not prevent CO sub(2)-induced changes in Net Primary Productivity (NPP) or biomass; indeed, if CO sub(2) fertilization is significant, then a climate-stabilized world could have higher NPP than our current world. Nevertheless, there are many reasons why geoengineering is not a preferred option for climate stabilization.
