Hematite-rich spherules are thought subsequently to have formed in the subsurface as concretions. These interpretations led to an inferred abundance of water and that Mars was accordingly once habitable. Here, however, with evidence from impact surge flows caused by explosive volcanic eruptions and from nuclear test site explosions and resulting ground surges, an alternative explanation for these sedimentary-like layered deposits is offered with a ground-confined turbulent flow of rock fragments, salts, sulphides, brines and ice produced by a giant meteorite impact. Layered structures are not unique to water deposition; plots are figured of volcanic surge deposit thckness related to radial distance from the eruption. The high-albedo, cross-laminated strata at the Opportunity landing site is seen in orbital photographs extending apparently, over tens of thousands of km (super 2) , and a key issue is the size of an impact crater that could produce such a large deposit. One possibility is the 450-km wide crater Schiapelli sited about two crater diameters to the E of this site. Alternatively the surge deposits may derive from numerous, smaller and closer impacts and details are discussed. A further argument against the evaporating lake scenario, is that most soluble salts (halides, Mg sulphate) occur together with the least soluble salts (Ca sulphate, jarosite); on Earth the least soluble soluble salts evaporate first and line coastal/basin areas, while the last-evaporating salts occur towards the centres of basins. Moreover, there is a lack of clay minerals in the deposits (from acid-rock interactions), near-uniform size distributions and high sphericity of the constituents, and an absence of a basin boundary.

AN - 70143856; 16506436 AB - Scorpionism is a public health problem in several regions of the world. The highest mortality, with over 1000 deaths per year, has been reported in Mexico. We analysed the significance of climatological variables to predict the incidence of scorpion stings in humans in the state of Colima (Mexico) for the years 2000-2001. The pluvial precipitation (mm), the evaporation (mm), and the mean, maximum, and minimum temperatures (degrees C) were obtained from local meteorological offices. There are approximately 3 stings/year per 1000 people in municipalities of Colima and Villa de Alvarez and about 18-30 stings/year per 1000 people in the rest of the municipalities. There is very little rain and there are few stings in the winter when the minimum temperature is below about 16 degrees C. The number of scorpion stings is independent of the actual rainfall when this is above 30 mm/month. Using multiple linear regression, we used a backward model selection procedure to estimate that the minimum temperature is correlated with scorpion sting incidence with a statistically significance of 95%. We briefly discuss the application of predictive models of scorpion sting incidence in the appropriate allocation of antivenom serum in hospital clinics.

AN - 69061480; 16392626 AB - Millions of dollars have been spent improving the bioterrorism surveillance capabilities of the public health system. Yet relatively little attention has been paid to the benefits that such expenditures yield. To assess the impact of an aerosol release of Bacillus anthracis, this article collects the available evidence on the potential benefits of environmental detection relative to the costs of a bioterrorist attack like the one in 2001, which occurred in the absence of any such detection. The cost-benefit model shows that biological surveillance that reduces time to treatment to 48 hours yields economic benefits that range from $1.11 billion to $50.74 billion depending on the nature of the release and the value of statistical life one assigns. The author collected annual costs of the current biological surveillance system, BioWatch, for the cost-benefit analysis. The costs of BioWatch are justified when the probability of a biological threat exceeds 1.26 percent.

Appropriately designed models can describe the interactions of competing processes at a range of spatial and time scales, and hence are critical for connecting the advancing capabilities for materials characterization at the atomic scale with the macroscopic behavior of complex Earth systems. Reactive transport modeling has had a significant impact on the treatment of contaminant retardation in the subsurface, the description of elemental and nutrient fluxes between major Earth reservoirs, and in the treatment of deep Earth processes such as metamorphism and magma transport. Active topics of research include the development of pore scale and hybrid, or multiple continua, models to capture the scale dependence of coupled reactive transport processes. Frontier research questions, that are only now being addressed, include the effects of chemical microenvironments, coupled thermal-mechanical-chemical processes, controls on mineral-fluid reaction rates in natural media, and scaling of reactive transport processes from the microscopic to pore to field scale.

The present study considers variations of permeability, radiogenic heating, and body radius. The model accounts for the radial variation of gravity within the body, melting of ice, freezing of liquid water, and variable water properties and incorporates a realistic equation of state for water. Some regions of a parent body experience no pore water flow while other regions experience hundreds of pore volumes of liquid water flow. The spatial heterogeneity in pore water flow reflects the convective pattern in the body. Hydrothermal alteration of minerals inside the parent body will accordingly vary greatly with location in the body, and one parent body could be the source of chemically diverse meteorites.

We use trace element concentrations from individual minerals in the Apollo 14 high-Al basalts to evaluate both endogenic and exogenic models. The data show that if the Apollo 14 high-Al basalts were produced by melting within the lunar mantle, these basalts cannot be related to one another by closed-system fractional crystallization of a single basaltic melt. Rather, the trace element data show that variable amounts of a KREEP component were added to the basalts by either assimilation, mixing into mantle sources, or impact melting. Single-stage assimilation-fractional crystallization models can only explain the data from this study if an excessively large mass of urKREEP is assimilated into the parent magma before olivine crystallization. Alternatively, the trace element data can be explained if the Apollo 14 high-Al basalts were produced by melting multiple Al-rich mantle sources that contain different amounts of urKREEP. Finally, for impact melting to be a relevant process, the data require that multiple large impact melts be formed from mixed KREEP-rich target lithologies. The resulting impact melts must then crystallize to produce basalts with igneous textures, high Al (sub 2) O (sub 3) concentrations, uniform major element compositions, and a wide range of incompatible trace element concentrations.

Here, we demonstrated the power of microsphere-based immunoassay for high-sensitivity detection and accurate differentiation of influenza viruses. The effects of sample volume and bead number on the assay sensitivity of viral antigen detection were studied. Compared to enzyme-linked immunosorbent assays, flow-based bead assays provided ^610-fold lower detection limit for viral particle detection and performed similarly for recombinant viral hemagglutinin protein detection. A four-plexed assay for influenza virus typing and influenza B virus sublineage characterization was developed to demonstrate the potential for multiplexed viral antigen detection and differentiation.

Sterne under Conditions of Iron Starvation AN - 19275395; 7009001 AB - The siderophores of Bacillus anthracis are critical for the pathogen's proliferation and may be necessary for its virulence. Bacillus anthracis str. Sterne cells were cultured in iron free media and the siderophores produced were isolated and purified using a combination of XAD-2 resin, reverse-phase FPLC, and size exclusion chromatography. A combination of super(1)H and super(13)C NMR spectroscopy, UV spectroscopy and ESI-MS/MS fragmentation were used to identify the primary siderophore as petrobactin, a catecholate species containing unusual 3,4-dihydroxybenzoate moieties, previously only identified in extracts of Marinobacter hydrocarbonoclasticus. A secondary siderophore was observed and structural analysis of this species is consistent with that reported for bacillibactin, a siderophore observed in many species of bacilli. This is the first structural characterization of a siderophore from B. anthracis, as well as the first characterization of a 3,4-DHB containing catecholate in a pathogen.

Capillary electrophoresis (CE) coupled to electrospray ionization (ESI) time-of-flight (TOF) MS serves to separate and mass-measure the thousands of polypeptides contained in human urine. Statistical analysis of the differences between healthy control samples and patients with focal-segmental glomerulosclerosis, membranous glomerulonephritis, minimal change disease, IgA nephropathy, and diabetic nephropathy validates multiple biomarkers for the control and each of the diseases. To identify those biomarkers, we employ preparative CE, enabling direct infusion ESI MS analysis, followed by sample manipulation and reanalysis where necessary. We show how tandem Fourier transform ion cyclotron resonance (FT-ICR) MS identifies these sometimes large (>8 kDa) biomarkers. Critically, we maintain connectivity between the CE TOF MS data and the ICR data used for biomarker identification.

The new responses include for the first time a comprehensive treatment of bremsstrahlung photons, as well as actual dimensions and electronic noise. The new responses yield energetic (0.05-1.5 MeV) electron fluxes accurate to within a factor of 2. Whenever the electron energy spectra are sufficiently soft, the new electron fluxes agree reasonably well with previous estimates. However, for hard electron energy spectra often found after geomagnetically active times, significantly lower electron fluxes are obtained from the same observed counts. For such cases, previously obscured spectral features are clearly observed, and the plasma analyzer and SOPA electron fluxes show much better agreement.

a new archive of surface processes AN - 868009444; 2011-046076 AB - The deep-sea gorgonian coral Primnoa spp. live in the Atlantic and Pacific Oceans at depths of 65 to 3200 m. 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.

A population of 100 agents inhabited a landscape of 20x20 squares containing five sources of food. Agents moved about the landscape in search of food, shared, stole, mated, produced offspring, & ultimately died of old age. Violence & revenge reduced the survival probability of the population &, for surviving populations, replaced hunger as the second leading cause of death after old age. Excluding large segments of the population from violence & revenge significantly improved survival rates. Tolerance to transgressions reduced the number of agents killed in revenge attacks. Higher population density increased the number of revenge deaths but also increased the survival rate of the total population. Decreasing the food supply for a fixed initial population resulted in more deaths due to violence & revenge. Flight from known aggressors enhanced the survival of the total population, at the expense of social cohesion. When killing had a positive social value the survival rate of the total population increased as the number of revenge killings decreased. These results are discussed in the context of ethnographic observations of a number of egalitarian societies. Tables, Figures, Appendixes, References. Adapted from the source document.

Local and regional tephra correlations of more than 20 tephra units were established using major and trace element data of discrete and purified bulk glass samples within the Konso study area. Eleven correlative marker tuffs were recognized in stratigraphic sections of both the Konso Formation and the Omo-Turkana Basin sediments in southern Ethiopia and northern Kenya. The Turoha, Hope, Ivory, Bright White, and Boleshe Tuffs in the Konso Formation, and the Upper White Tuff in the overlying terrace deposits are securely correlated with the KBS, Akait, Lokapetamoi, Chari, Lower Nariokotome, and Silbo Tuffs of the Omo-Turkana Basin, using least mobile major elements (CaO, Fe (sub 2) O (sub 3) *, and TiO (sub 2) ) and geochronology. Preliminary correlations are also suggested between the Konso Formation distal tephra and proximal units of the Quaternary caldera-forming silicic centers in the central sector of the MER. The strongly peralkaline tuffs of the Konso Formation are compositionally similar to proximal eruptions mostly located along the Quaternary axial rift zone of the southern, central, and northern sectors of the MER. The tephra correlation provides information about the temporal and spatial features of the volcanic and tectonic processes recorded in the evolving basins. Thickness and sedimentation rate were determined for both the Konso Formation and the Omo-Turkana Basin sections, measured between the Turoha (=KBS; 1.91+ or -0.03 Ma) and the Bright White (=Chari; 1.40+ or -0.02 Ma) Tuffs. Although the lithostratigraphic sequence at the Konso study area is younger, sedimentation rate within the Konso Formation was comparable to that of the Koobi Fora Formation, higher in the Nachukui Formation, and lower in the Shungura Formation. Local and regional differences in thickness and sedimentation rates within the Plio-Pleistocene deposits of the Konso, Shungura, Nachukui, and Koobi Fora Formations may be attributed to erosion associated with increased topographic gradients maintained by continued subsidence mostly along axial fault zones of basins and uplift along the margins of the broadly rifted zone of the Omo-Turkana Basin and the southern sector of the MER.

Material softening in granular media was investigated and the equipment and methods are described. The granular medium consisted of glass beads (0.6 to 0.8 mm diameter) simulating fault gouge, enclosed in a pressure container with two piezo-electric transducer pistons and receiver, with the optimization of the propagation of coherent P waves in a resonance experiment. In a slow dynamics experiment the equilibrium, elastically linear modulus of the sample was first measured by applying a low-amplitude strain step-sweep, and a resonance curve constructed recording the amplitude at the resonance peak. In a model of rock failure, it is shown how wave nonlinear dynamics force a fault system in a critical, jammed state to failure by softening and weakening of the fault gouge. The experiments and a softening-to-weakening model indicate that dynamic elastic nonlinearity of the fault gouge explains dynamic triggering in response to seismic waves, with slow dynamics being perhaps responsible for delayed triggering. The triggering mechanism requires a weak fault or one with low effective P, a fault in a critical state and dynamic strain amplitudes > approximately 10 (super -6) . Thus even with such small strains, the dynamic elastic nonlinear behaviour of fault gouge disturbed by a seismic wave may trigger earthquakes at remote distances from the epicentre.

Emphasis was placed on the role of neoformed precipitates in controlling Zn speciation, mobility and bioavailability under different environmental conditions. Twelve years after remediation, the pH of the treated and non-treated soil differed by only 0.5 pH unit. Using state-of-the-art electron and X-ray microscopies in combination with micro-focused extended X-ray absorption fine structure (mu -EXAFS) spectroscopy, no major differences in Zn speciation were found between samples of the treated and non-treated soil. In both soils, 30% to 50% of Zn was present in smelter related minerals (willemite, hemimorphite or gahnite), while 50% to 70% of Zn was incorporated into newly formed Zn precipitates. Contrary to the non-treated soil, the treated soil did not contain gahnite or sphalerite; it is possible that these minerals were dissolved under the higher pH conditions at the time of treatment. Desorption experiments, using a stirred flow technique with a 0.1 mol/L CaCl (sub 2) (pH 6.5) and a HNO (sub 3) (pH 4.0) solution were employed to determine the exchangeable Zn fraction and the Zn fraction which will be mobilized under more extreme weathering conditions, respectively. No significant differences were found in desorption behavior between the treated vs. non-treated soil. Bioavailability tests, using the R. metallidurans AE1433 biosensor showed that approximately 8% of total Zn was bioavailable in both the treated and non-treated soils. It was concluded that the incorporation of Zn into newly formed precipitates in both the treated and non treated soils leads to a significant natural attenuation of the exchangeable/bioavailable Zn fraction at near neutral pH conditions. At lower pHs, conditions not favorable to the formation of Zn precipitates, the pool of Zn associated with the secondary Zn precipitates is potentially more bioavailable.

Unfortunately, the moving water table problem is notoriously computationally demanding. Accurate solutions can be obtained using two-phase (air/water) simulations, but these are not practical for many field-scale problems where large (hundreds of thousand to millions of gridblocks) models are often used. In addition, these models require calibration (hence hundreds to thousands of forward runs) and so efficient run-times are necessary. Simplified single-phase approaches have been developed, such as that implemented in MODFLOW2000. There has been concern, however, when using the wetting/re-wetting capability on large scale problems with uniqueness of the solution (Naff et al. 2003) and the ability to re-wet efficiently. We have developed an alternative single-phase, simplified numerical approach, which incorporates selected aspects of multi-phase flow theory. We incorporate this approach into the code FEHM and apply it to analysis of unconfined aquifers. This method has some advantages (and a few disadvantages) when compared to three established methods: that used in MODFLOW, the full two-phase numerical formulation, and the Richards' equation approach. The new formulation is compared with the other methods on several problems ranging a simple drawdown analysis model to a complex basin scale model. The formulation is evaluated in terms of accuracy, numerical stability, uniqueness of the solution, and computational efficiency. Naff, R., Banta, E., and J.

Preliminary strain data are reported here for the Jurassic Twin Creek and Triassic Ankareh Formations. Mesoscopic to microscopic strain is accommodated by a variety of structures, which depends on lithology. Micritic limestone displays spaced cleavage and veins; bioclastic limestone contains plastically deformed fossils; redbeds have rough cleavage; and well bedded sandstone displays minor fold and fault networks (including wedge faults and oblique-slip, cross striking faults that produce differential shear and minor longitudinal extension). Two dimensional strain values were estimated using mass balance relations for spaced cleavage in micritic limestone, deformed crinoids in bioclastic limestone, and reduction spots in redbeds. Three-dimensional strain was estimated using 2D values for three perpendicular planes for selected samples. The XY strain plane and cleavage are about perpendicular to bedding in most areas, reflecting early layer-parallel shortening. Principal shortening (Z) directions (and cleavage poles) fan over 90 degrees around salient, roughly perpendicular to structural trends, reflecting a combination of initial curvature and vertical axis rotation of early fabrics. Principal shortening values vary from <10% in the frontal Hogsback thrust sheet where cleavage is weak to absent, to 15 to 30% in the more interior Crawford sheet where cleavage intensity is moderate to strong. Minor longitudinal extension parallel to structural trends is widespread, possibly reflecting a component of radial transport and development of secondary curvature. In general, strain intensity increases in more interior thrust sheets, and westward within individual sheets. Strain intensity in Ankareh redbeds and Twin Creek limestones are similar in many areas, but locally the Ankareh appears to have lower strain, which may reflect unrecognized minor faulting, or detachments that separate packages with differential shortening. Regional patterns indicate that internal strain is a significant component of total deformation in many areas, and should be taken into consideration when constructing and restoring cross sections.

In an effort to understand origins of orogenic curvature, a collaborative effort is underway to determine the 3D kinematic history of the Wyoming salient of the Sevier fold thrust belt, combining paleomagnetic analysis, fracture and strain studies, and construction of balanced cross sections. Preliminary data are reported here on 60 paleomagnetic sites collected from the Triassic Ankareh Formation from throughout the salient. Two components of magnetization are present: 1) a viscous magnetization acquired in a recent field, and 2) a characteristic remanence magnetization that has dual polarity and a linear decay toward the origin of demagnetization diagrams. Preliminary fold tests indicate pre-folding magnetization for most Ankareh sites. The estimated regional pre-folding inclination of about +15 degrees agrees well with the expected Late Triassic local inclination value for Wyoming, suggesting a primary age of magnetization. In situ declination values of the characteristic remanent magnetization show considerable regional variations (up to 90 degrees), recording significant relative vertical-axis rotations around the salient. Moreover, systematic and differentiable thrust sheet rotation patterns are emerging that are consistent with overall structural trends around the salient. Pronounced counter-clockwise rotations are widespread in northern sections of the salient near the intersection of the fold-thrust front with the Teton/Gros Ventre foreland uplifts. Smaller clockwise rotations occur in south-central sections where the fold-thrust belt bows outward north of the Uinta foreland uplift. Additionally, local rotations are associated with transfer zones within individual thrust sheets. Overall rotation patterns in the Wyoming salient suggest that at least part of the observed curvature is secondary and care should be taken when constructing classic cross-sections perpendicular to structural trends, which may have been progressively rotated during deformation.

Billions of tons of these produced waters are generated each year. Produced water often contains hazardous, soluble organic compounds such as benzene, toluene, ethylbenzene, and xylenes (BTEX). We are investigating a low-cost treatment system for produced water using surfactant-modified zeolite (SMZ). The goal of the treatment system is to allow produced water to be put to a beneficial use such as dust control or make-up water at production facilities. Previous laboratory and field investigations have shown that SMZ is an effective sorptive media for the removal of BTEX from produced water. It has also been demonstrated that SMZ saturated with BTEX is readily regenerated via air stripping with little loss of sorption capacity over 10 sorption/regeneration cycles. We are currently examining whether the SMZ remains an effective sorptive medium over long-term (up to 100) repeated sorption and regeneration cycles. Loss of sorption capacity and loss of surfactant from zeolite particles are monitored through chemical analysis of effluent waters. Additionally, we monitor SMZ particle breakdown and the resultant impact on the hydraulic properties of the column. The results from these experiments will have implications for future pilot scale tests of the SMZ system.

Because the displacement field is comprised of translation, rotation, and strain, with manifestation of such components changing throughout the temporal and spatial evolution of orogenic systems, the main objective of our integrated approach is to develop a comprehensive three-dimensional kinematic model. Preliminary results from fracture analyses within the Triassic Ankareh and Jurassic Twin Creek Formations suggest that deformation in the elastico-frictional regime occurred at several stages within the development of the Wyoming salient. Information gathered from the fractures include: surface morphology, architecture, abutment relationships, density, spacing, offset and orientation. Generally, our observations indicate that the filled/ornamented fractures with the most complex abutment relationships, varied architectures, highest densities, and range of orientations appear to coincide with the oldest phases of deformation. On the other hand, most of the open fractures, often without any perceptible offset, and most typically found to be oriented in an E-W direction, seem to post-date much of the thrust-related deformation. The style of fracturing is somewhat different in the Ankareh and Twin Creek Formations and also seems to vary spatially within the thrust sheets (Absaroka, Prospect and Hogsback), and in comparing the nature of fracturing among thrust sheets. In addition, the characteristics of the fractures are highly affected by local structures. Thus, our analysis is conducted at different scales: from the salient as a whole to individual folds. While fracture density increases towards the fault zones of the major thrust sheets, local populations also increase near smaller wedge faults. In terms of the relationships fractures may have with the other elements we are analyzing (strain and rotations), we predict that regions with the highest rotations will spatially correspond to the most complicated fracture patterns. In addition, in many regions, high strains may be accommodated by cataclastic flow and displacement along minor faults.

This study was undertaken to determine if there are significant differences between bulk and rhizosphere soils from the Idaho National Laboratory (INL) with respect to their ability to bind Cs. The capacity of FES on bulk and rhizosphere soil materials and conditional Cs/K selectivity of FES ( (super c) K (sub ex) (super FES) ) were determined as a function of both soil type and initial exchanger composition. The FES capacity was significantly higher in untreated, Ca-saturated, and K-saturated rhizosphere soil materials as compared with bulk soil materials. Sorption-desorption isotherms were obtained at Cs concentrations between 5 X 10 (super -9) and 5 X 10 (super -6) M. No difference in Cs sorption was observed between bulk and rhizosphere soil materials. The composition of the exchanging solution had the greatest effect on the magnitude of Cs desorption; significantly more Cs was desorbed in the presence of KCl than in either CaCl (sub 2) or a mixed-cation soil solution. In addition, Cs desorption was greater from rhizosphere soil materials relative to bulk soil materials. Cesium selectivity with respect to both Ca and K was significantly suppressed by weathering in the rhizosphere. We conclude that enhanced weathering in the rhizosphere increased the Cs sorption capacity of FES, but also reduced Cs selectivity on these sites. Enhanced Cs desorption from rhizosphere INL soils is likely in the presence of actively growing plants and associated microorganisms.

Growth of magma chambers requires that the rate at which heat is supplied by new magma exceeds the rate of cooling. Analysis of this thermal balance indicates that climate may play a role in whether the magma body attains large size or freezes between magma pulses. The rate of cooling depends on whether heat transport occurs by conduction or convection. Convection can move heat 10 times faster than conduction, but in arid regions recharge is limited and convection can be starved. For sheets of magma , where the problem is essentially 1-dimensional, the relevant energy balance is approximated by the dimensionless number M = q/rho LV, where q is the heat flux out the top of the body ( approximately surface heat flow), rho is density, L is latent heat of crystallization, and V is the rate at which new magma is accreted to the body. For M>1 heat loss exceeds the rate at which new heat is advected in by fresh magma and magma increments freeze as they are accreted; for M<1 the magma body grows. For heat flow of 200 mW/m (super 2) ( approximately 5 HFU), M=1 when V is approximately 1 cm/yr. Highly elevated heat flows of 1000-2000 mW/m (super 2) (regional average for Yellowstone) would require 5-10 cm/yr of magma accretion. Such a rate is unlikely, and this high heat flow probably reflects convective cooling that currently outpaces magma accretion. We therefore propose that development of magma bodies capable of erupting with large-scale caldera collapse should be favored in regions that were arid when magma accumulated. In the Andes, large Quaternary calderas are unknown in the northern tropics and southern temperate zone but are abundant in arid Bolivia and northern and central Chile. The huge Altiplano-Puna volcanic complex occurs in one of the driest regions on Earth. Other major Cenozoic ignimbrite provinces (Great Basin, Sierra Madre Occidental, Snake River plain) developed in arid regions. Other factors (e.g., decreases in permeability) can decrease M and promote development of large magma bodies in wet regions, but precipitation may exert a first-order control on whether a large magma body or incremental pluton forms as magma accumulates.

More than two-thirds of the faults studied display preferential alteration and cementation compared to adjacent protolith. Stable isotope analyses indicate that smectite alteration and calcite cementation result from low-temperature meteoric fluid-fault interaction. Fault-zone microstructures, rare earth element signatures, and mineralogy indicate that smectite was introduced to deformation-band fault zones by a combination of translocation from the surface and in situ alteration of fault gouge. Rod-shaped calcite microcrystallites and the close association of calcite with plant roots suggest a combination of pedogenic, biologically mediated and physicochemical precipitation. Enrichment in smectite and calcite modified major oxide and trace element contents of deformation bands with respect to protolith. Collectively, these observations indicate that these faults have served as, and may still be, zones of preferential vadose-zone fluid flow and transport. These processes modify fault-rock permeability; affect the transport of solutes via processes such as dissolution, precipitation, and adsorption; and change the mechanical properties of the fault zone. Smectite and calcite result in localization of deformation, effectively halting the further development of deformation bands. Vadose-zone alteration therefore is one way to produce a clay-rich fault core at early stages in a fault's history, resulting in fault-zone weakening and localization of deformation. Progressive burial of growth faults can subsequently bring fault cores into the seismogenic zone.

The 89,000-acre ranch is now part of the U.S. National Forest and is governed by the Valles Caldera Trust. In 2002, new geologic mapping commenced within the VCNP and at present this mapping is being published as a series of 7.5-minute quadrangles by the New Mexico Bureau of Geology & Mineral Resources (Socorro, NM). Two of the four quadrangles that cover significant portions of the caldera (Redondo Peak and Bland) are now complete and two others will be finished by 2006 (Valle Toledo and Valle San Antonio). Eventually, the geology of the Valles Caldera will be published as a special color map at 1:24,000. The 22-km-diameter Valles Caldera is the world's type resurgent caldera, and it is the source of the famous Bandelier Tuff. The southwestern resurgent dome is also host to a classic 200 to 300 degrees C, liquid-dominated hydrothermal system circulating at depths of 600 to 2000 m. The new mapping has contributed to the following major research findings: 1, Uplift and faulting of the Valles resurgent dome have exposed large, rootless megabreccia blocks composed of precaldera rocks immersed in densely welded, intracaldera Bandelier Tuff. The largest blocks are 0.2 to 2.0 km long, consisting of Pennsylvanian through Quaternary rocks. 2, Maximum resurgence of at least 1000 m occurred immediately after caldera formation. High-precision Ar/Ar dates indicate that this structural resurgence took place within 54 ka of caldera formation. Resurgence averages 3.7 cm/yr and probably not less than 1.9 cm/yr. 3, Many lakes have existed in the caldera at various times. The earliest formed immediately after the caldera formed and has left tilted lacustrine and hydromagmatic deposits draped around the lower to middle flanks of the resurgent dome. Another lake may have filled much of the caldera at around 800 ka. Younger lakes occurred in the north and east valleys of the caldera at about 550 to 520 ka. A final lake occurred in Valle Grande at roughly 50 to 60 ka.

These models are of limited use for the unsaturated vadose zone where the concentration and migratory behavior of radioisotopes are often time dependent. We present here a model simulating the non-steady state situation. Applicable to vadose as well as phreatic (saturated) layers, the model provides constraints on in-situ radioisotope migration in dissolved and colloidal phases in terms of retardation factor and rock-water interaction (or water transit) time. For the mobility of uranium, the model shows that water percolating through the vadose zone will have its U concentration and ratio (super 234) U/ (super 238) U linearly correlated under the ideal condition of a constant removal of the two U isotopes from vadose-zone solids. By knowing the non-flushing period between two major rain events, the intercept and slope of the linearity serve to constrain removal rates of the two uranium isotopes from solids to the solution through dissolution and alpha recoil. At Pena Blanca, the uneven distribution of rainfall between winter/spring (dry) and summer/fall (wet) results in a seasonal variability of uranium removal rate within the unsaturated zone. Data on (super 234) U/ (super 238) U indicate a higher uranium dissolution rate relative to alpha-recoil rate during drier seasons, possibly reflecting increased oxygenation in vadose layers.

Piezometric information is being collected to understand groundwater flow at local and regional levels as part of an ongoing natural analogue study of radionuclide migration. Water level monitoring reported at these and other wells in the region is combined with archival data to provide a better understanding of the hydrology at Nopal I. Initial results suggest that the local hydrology is dependent on the regional hydrologic setting and that this groundwater system behaves as an unconfined aquifer. The region is dominated by an alternating sequence of highlands and basins that step down from west to east. The Sierra de Pena Blanca was downdropped from the cratonic block to the west during Cenozoic extension. The Nopal I area is near the intersection of two large listric faults, and the questa of ash flow tuffs that hosts the deposit has been subjected to complex structural events. The Pena Blanca uranium district was originally characterized by 105 airborne radiometric anomalies, indicating widespread uranium mineralization. The Nopal I uranium deposit is located in the Sierra del Pena Blanca between the Encinillas Basin to the west, with a mean elevation of 1560 m, and the El Cuervo Basin to the east, with a mean elevation of 1230 m. The Nopal I +10 level is at an intermediate elevation of 1463 m, with a corresponding groundwater elevation of approximately 1240 m. The regional potentiometric surface indicates flow from west to east, with the El Cuervo Basin being the discharge zone for the regional flow system. However, it appears that the local groundwater potential beneath the Nopal I site is more in accordance with the water table of the El Cuervo Basin than with that of the Encinillas Basin. This might indicate that there is limited groundwater flow between the Encinillas Basin and the Nopal I area.

In 2003, three groundwater wells were drilled directly adjacent to (PB-1) and approximately 50 m on either side of the uranium deposit (PB-2 and PB-3) in order to evaluate uranium-series transport in three dimensions. After drilling, uranium concentrations were elevated in all of the three wells (0.1-18 ppm) due to drilling activities and subsequently decreased to approximately 5-20% of initial values over the next several months. The (super 234) U/ (super 238) U activity ratios were similar for PB-1 and PB-2 (1.005 to 1.079) but distinct for PB-3 (1.36 to 1.83) over this time period, suggesting limited mixing between groundwater from these wells. Regional groundwater wells located up to several km from the deposit also have distinct uranium isotopic characteristics. We can model the decreasing uranium concentrations in the newly drilled wells with a simple one-dimensional advection-dispersion model, assuming uranium is introduced as a slug to each of the wells and transported as a conservative tracer. In this model, the relative uranium concentrations are dependent on both the longitudinal dispersion as well as the mean groundwater flow velocity. These parameters have been found to be correlated in both laboratory and field studies (Klotz et al., 1980). Using typical relationships between velocity and dispersion for laboratory and field studies along with the relationship observed from our uranium data, estimates of both velocity (1-10 m/yr) and dispersion coefficient (1E-5 to 1E-2 cm (super 2) /s) can be obtained. While these results and the limited productivity of these wells consistently suggest limited groundwater flow and mixing, additional work with artificial tracers should better establish groundwater flow velocities and gradient at this site.

The effectiveness of the barrier is characterized by in-situ retardation factor, i.e., the transport rate of a radionuclide relative to that of groundwater. As part of natural analog studies of the OSTI program of the U.S. Department of Energy, we are performing such a characterization by using naturally-occurring decay-series radioisotopes as an analog. We collected large-volume (>1000 liters) groundwater samples from three wells (PB, Pozos, and PB4, respectively) near the Nopal I uranium ore site at Pena Blanca, Mexico, by using an in-situ Mn-cartridge filtration technique for analysis of short-lived decay-series radionuclides. Results show that the activities of short-lived radioisotopes (Ra-228, Ra-224 and Ra-223) and activity ratios of Ra-224/Ra-228 and Ra-224/Ra-223 are higher at PB and Pozos than at PB4. In contrast, the Po-210 activity is much lower at PB and Pozos than at PB4. The high Ra activities and activities ratios at PB and Pozos are attributable to the high alpha-recoil input from the aquifer fractures, while the high Po-210 activity at PB4 is due to the enhanced colloidal transport. Based on a uranium-series transport model, we estimate that the in-situ retardation factor of Ra is (0.43+ or -0.02)X10 (super 3) at PB, (1.68+ or -0.08) X 10 (super 3) at Pozos, and (1.19+ or -0.08) X 10 (super 3) at PB4 and that the mean fracture width in the aquifer rocks is about 0.23 & mum at PB, 0.37 & mum at Pozos, and 4.0 & mum at PB4, respectively. The model-derived large fracture width at PB4 provides additional evidence to support the inference from the Po-210 measurements that particle-reactive radionuclides are transported mainly as colloidal forms through the large fractures in groundwater. Our model also suggests that in addition to alpha recoil, decay of Ra-226 from the adsorbed phases on the fractures contributes a significant source of Rn-222 to groundwater. The information obtained from this study provides useful testing and validation for the Yucca Mountain total system performance assessment model (TSPA).

The initial pumping to condition the wells was completed during December 2003. The PB-1 well, drilled immediately adjacent to the Nopal I ore body, was continuously cored to a depth of 250 m, terminating 20 m below the top of the measured water level. The PB-2 and PB-3 wells, which were drilled on opposite sides of PB-1 at a radial distance of approximately 40 to 50 m outside of the remaining projected ore body were also drilled to about 20 m below the top of the measured water level. Each test well was completed with 4-inch (10.2-cm) diameter PVC casing with a slotted liner below the water table. Initial conditioning of all three wells using a submersible pump at low pump rates [less than 1 gallon (3.8 l) per minute] resulted in measurable draw down and recoveries. The greatest drawdown ( approximately 15 m) was observed in PB-2, whereas only minor (<1 m) drawdown occurred in PB-3. For PB-1 and PB-2, the water turbidity decreased as the wells were pumped and the pH values decreased, indicating that the contamination from the drilling fluid was reduced as the wells were conditioned. Test wells PB-1 and PB-2 showed increased inflow after several borehole volumes of fluid were removed, but their inflow rates remained less that the pumping rate. Test well PB-3 showed the smallest drawdown and least change in pH and conductivity during initial pumping and quickest recovery with a rise in measured water level after conditioning. The 195 gallons (750 l) of water pumped from PB-3 during conditioning was discharged through a household sponge. That sponge showed measurable gamma radiation, which decayed to background values in less than 12 hours. Preliminary interpretations include filtration of a radioisotope source with a short half-life or of a radioisotope that volatized as the sponge dried, such as Rn-222 and its short-lived daughters. No filtration was used during the pumping of PB-2 and counts stayed at background were during the pumping of BP-1.

In the 1970s, the Pena Blanca region was a major target of uranium exploration and exploitation by the Mexican government. Since then the Nopal I uranium deposit has been studied extensively by researchers in the U.S., Mexico, and Europe. The Nopal I deposit represents an environment similar to that of the proposed high-level radioactive waste repository at Yucca Mountain, Nevada in many ways. Both are located in semi-arid regions. Both are located in Tertiary rhyolitic tuffs overlying carbonate rocks that have been subjected to basin and range-style tectonic deformation. Both are located in a chemically oxidizing, unsaturated zone 200 m or more above the water table. The alteration of uraninite to secondary minerals at Nopal I may be similar to the alteration of uranium fuel rods in this type of environment. Investigations at Nopal I and in the surrounding Sierra Pena Blanca have included detailed outcrop mapping; analysis of drillcore, geophysical well logs and cuttings; hydrologic and isotopic studies of flow and transport; studies of mineral alteration; modeling; and performance assessment.

These two units overly the Pozos conglomerate formation and Cretaceous limestone. Three new vertical diamond drill holes (DDHs) were recently drilled at Nopal I. DDH-PB1 with continuous core was drilled through the Nopal I Deposit and two additional DDHs were drilled approximately 50 m on either side of the cored hole. These DDHs terminate 20 m below the current water table, thus allowing the detection of possible gradients in radionuclide contents resulting from transport from the overlying uranium deposit. Primary uraninite within the main ore body is rare and fine-grained ( approximately 50 micrometers), thus making geochronology of the Nopal I Deposit very difficult. Uranium, lead and oxygen isotopes can be used to study fluid-uraninite interaction, provided that the analyses are obtained on the micro-scale. Secondary ionization mass spectrometry (SIMS) permits in situ measurement of isotopic ratios with a spatial resolution on the scale of a few mu m. Preliminary U-Pb results show that uraninite from the main ore body gives an age of 32+ or -8 Ma, whereas uraninite from the uraniferous Pozos Conglomerate that lies nearly 100 m below the main ore body and 25 meters above the water table, gives a U-Pb age that is <1 Ma. Oxygen isotopic analyses show that uraninite from the ore body has a delta (super 18) O= -10.8ppm, whereas the uraninite within the Pozos Conglomerate has a delta (super 18) O= +1.5ppm. If it is assumed that both uraninites precipitated from meteoric water (delta (super 18) O= -7ppm), then calculated precipitation temperatures are 55 degrees C for the uraninite from the ore body and 20 degrees C for uraninite hosted by the Pozos Conglomerate. These temperatures are consistent with previous studies that calculated precipitation temperatures for clay minerals associated with uraninite.

The wells penetrate through the Tertiary volcanic section down to the Cretaceous limestone basement, and intersect the top of the regional aquifer system. The PB-1 well, drilled immediately adjacent to the Nopal I ore body, was cored to a depth of 250 m, thus providing an opportunity to document the local stratigraphy. The uppermost unit encountered in the PB-1 well is the Nopal Formation, a densely welded, crystal-rich rhyolitic ash-flow tuff. The cored section is highly altered and devitrified, with kaolinite, quartz, chlorite, and montmorillonite replacing feldspars and much of the groundmass. Breccia zones within the tuff contain fracture fillings of hematite, limonite, and goethite. A zone of intense clay alteration encountered in the depth interval 17.45-22.30 m was interpreted to represent the basal vitrophyre of this unit. Underlying the basal vitrophyre is the Coloradas Formation, which consists of a welded, lithic-rich rhyolitic ash-flow tuff. The cored section of this unit has undergone devitrification and oxidation, and has a similar alteration mineralogy to that observed in the Nopal Tuff. The Nopal I ore body is restricted to a brecciated zone that intersects these two volcanic units. A sharp contact between the Coloradas Tuff and the underlying Pozos Formation was observed at a depth of 136.38 m. The Pozos Formation in the PB-1 core consists of interbedded, poorly sorted sandstone and conglomerate layers. The conglomeratic clasts consist of subangular to subrounded fragments of volcanic rocks, limestone, and chert. Thin (2-6 m) intervals of intercalated pumiceous tuffs were observed within this unit. The contact between the Pozos Formation and the underlying Cretaceous limestone basement was observed at a depth of 244.4 m.

In contrast to the inner aureole (Pe and Fo zones), the progress of the talc-forming reaction is incomplete; significant quartz (Qtz) + dolomite (Dol) always persists, regardless of whether Qtz is disseminated within dolostone or in the form of chert nodules. Talc reaction progress is very heterogeneous even within restricted stratigraphic intervals. Quantitative estimates of reaction progress require detailed mapping of the distribution of Tc-bearing and Tc-absent nodules and thickness of Tc + calcite (Cc) reaction rims on outcrop scale. Initial results indicate that reaction progress is heterogeneous (1 to 50 moles Tc/m (super 3) rock; ave. 11), can be correlated to stratigraphy, and is generally much less (<10%) than previously measured in the Tr (200 moles Tr/m (super 3) rock), Fo (460 moles Fo/m (super 3) rock) and Pe (5000 moles Pe/m (super 3) rock) zones (Cook and Bowman, 2000). Calcite (Cc) samples from Tc reaction rims surrounding chert nodules have delta (super 18) O (sub SMOW) (13.4 to 19.8 permil) and delta (super 13) C (sub PDB) (-3.3 to -0.4 permil) values too low to be in isotope exchange equilibrium with the adjacent matrix dolomite (delta (super 18) O = 27.3 to 28.9; delta (super 13) C = 0.13 to 2.25) at the estimated T = 350 degrees to 400 degrees C for Tc formation. Measured delta (super O) (Dol-Cc) fractionations vary significantly between sites, ranging from +7.2 to +14.1 permil, much larger than equilibrium values of approx. 0.6 permil at 400 degrees C. These disequilibrium values may reflect variable kinetic impacts during CO (sub 2) evolution and transport accompanying Tc reaction, or variable inheritance of (super 18) O/ (super 16) O-depleted oxygen from chert nodules (delta (super 18) O = +8 to +18), or both. These field, petrologic, and isotopic characteristics of the Tc zone suggest that metamorphic processes in the outer Alta aureole are characterized by heterogeneous pore fluid composition, variable fluid flux and rock permeability, isotopic disequilibrium, and are influenced by reaction kinetics. Mechanisms that may be complicating fluid flow patterns and mineral reaction in the outer aureole include H (sub 2) O-CO (sub 2) fluid immiscibility or the development of multiple hydrothermal convection cells during evolution of the aureole.

Fabric development is largely dependent on compositional heterogeneity, which allows for mineral segregation. Connectivity, an important component of fabric, is a parameter used to describe the degree (amount) and the scale (domain size) of mineral segregation in a particular rock. Previous research suggests that the extent of fabric formation and mineral segregation may contribute to the development of anisotropic permeability, the strengthening or weakening of rock material, and the types of slip mechanisms operating in the fault zone. However, mineral connectivity has not been quantified, so its exact relationship to these characteristics is unknown. Quantification of mineral connectivity in cataclastic zones is an important step in characterizing these relationships. Because connectivity can vary depending on the scale of observation, the most appropriate quantification method is one that can analyze and quantify the size, shape, orientation, and spatial relationship of all rock constituents at a variety of scales. Anisotropic wavelet transforms (commonly referred to as wavelets) provide a mathematical method capable of objectively analyzing complex orientation and distribution data sets at any scale. Wavelets are mathematical functions that divide data information into different frequency components and analyze these components based on an assigned resolution representing scale. Here, we introduce the wavelet approach to cataclastic rocks and present our initial results of quantification of mineral connectivity at several scales in naturally faulted rock. In future work, such quantification will help elucidate the role of connectivity with the development of other physical properties, such as permeability and strength, of the fault zone.

Current estimates of water supply assume that water quality will remain constant over time. This study seeks to determine the extent to which this assumption is valid with respect to heavy metal contamination. Historical and modern trends in groundwater chemistry in the Espanola Basin, a sub-basin of the Rio Grande Rift, suggest that significant uranium contamination occurs locally in some areas. Isotopic analyses demonstrate that the source of the contamination is natural. Through water sampling, analysis, and modeling we are attempting to determine the mechanisms controlling the present spatial distribution of the uranium contamination and to predict the impact of current and future groundwater production on contaminant concentrations. Preliminary data analysis and modeling results suggest that both alkalinity and redox conditions are important factors in controlling spatial distribution of uranium in groundwater. Reactive transport modeling suggests that a simple model of groundwater flow, coupled with a kinetically-controlled silicate dissolution and uranium equilibrium reactions are consistent with generalized large-scale spatial trends. Local variations in uranium concentrations are apparently heavily influenced by redox conditions. Forty years of data from one wellfield in the basin clearly suggest that water quality deteriorated after several decades of pumping. The mechanism(s) responsible for the measured increases in uranium and arsenic concentrations are unknown; possibilities include either a purely physical mechanism such as enhanced extraction of deeper, older waters or a geochemical mechanism such as changes in alkalinity or redox states that affect trace element solubility. We present reactive flow modeling results at the regional scale which identify those locations within the aquifer which are the most vulnerable to future deterioration of water quality, and suggest how current estimates of water supply should be adjusted to reflect possible deterioration in quality.

Seventy-six perchlorate results, analyzed using an extremely sensitive method, were obtained from 47 well and spring locations representative of groundwater from the Sierra de Los Valles and Pajarito Plateau (LANL area), Espanola Basin, and springs along the Rio Grande north of Taos. Six distinguishable groundwater zones were analyzed based on location, age, and background water quality. About half the sites represent the regional or drinking-water aquifer beneath the Laboratory. Background water quality was determined by evaluating the major-ion chemistry for each site. Tritium and stable-isotope analyses provide information on recharge, residence time, and flow path. Hydrochemical and hydrogeologic relationships show sites east of Sierra de Los Valles in the mountain-front region to be young or modern in age (50 yr). Tritium data from springs located along the Rio Grande north of Taos possess both modern and sub-modern/paleo ages. Perchlorate concentrations in the LANL area were consistent; however, more variable concentrations were observed between the Los Alamos and Taos sites. This may result from natural variability, hydrogeologic, atmospheric, and/or other unidentified inputs. Nine precipitation samples collected in the LANL area do not contain perchlorate above 0.05 ppb (instrument detection limit). Establishing a background upper tolerance limit (UTL) (mean + 2) for waters within the Northern Rio Grande Basin enables investigators to discern if concentrations of perchlorate above the UTL are anthropogenic. The background UTL of 0.44 ppb was calculated from the 76 analytical results. This UTL is approximately ten times below any perchlorate health standard proposed by EPA or neighboring states.

Liquid chromatography-mass spectrometry/mass spectrometry (EPA SW846 method 8321A), with an instrument detection limit of 0.6 nm (0.06 ppb), was used during this investigation. Perchlorate consists of four-double covalent bonds between chlorine and oxygen (tetrahedral coordination), making this highly soluble oxyanion very stable and nonreactive in aqueous environments. Formation of natural perchlorate under strongly oxidizing conditions is possible through evaporation and production of ozone during electrical storms. These processes occur in northern New Mexico and may generate low concentrations of perchlorate during early stages of the hydrological cycle. Perchlorate does not adsorb onto inorganic surfaces, including hydrous ferric oxide, smectite, and manganese oxide, characterized by net-negative surface charges under circumneutral pH conditions (6.5 to 9.0). Physical processes including mixing and dispersion control the distribution of perchlorate in groundwater. The overall reduction of perchlorate to chloride is given by the following half reaction: ClO (sub 4) (super -) + 8H (super +) + 8e (super -) = Cl (super -) + 4H (sub 2) O, with an E (super o) of 1.39 volts (V) and an Eh (pH7) of 0.98 V. This reaction has relevance to natural systems such as wetlands and other microbially-active environments with plentiful and diverse electron donors. Perchlorate is reduced to intermediate compounds (chlorate [Cl(V)] and chlorite [Cl(III)]) and eventually to chloride in anaerobic environments by serving as a terminal electron acceptor during oxidation of acetate and other forms of reactive organic carbon. Perchlorate reduction is both thermodynamically and microbially enhanced under denitrifying conditions.

We have collected detailed depth profiles of vadose-zone perchlorate from 25 boreholes along a semiarid canyon in New Mexico. These profiles represent releases of perchlorate from a water treatment plant at Los Alamos National Laboratory that occurred over a nearly forty year period starting in the early 1960s. Although the perchlorate is anthropogenic, this study provides a proxy for the kind of behaviors that may occur during transport of natural perchlorate. In this canyon system, transport is multidimensional; mainly downward and longitudinal along the canyon length. Surface flow is largely ephemeral and there is alluvial groundwater (largely effluent-supported) present along part of the canyon. Profiles show that much of the perchlorate is still within the upper 100 m of a nearly 300-m thick vadose zone. Perchlorate has been observed in a perched intermediate aquifer (approximately 197 m deep) and in the regional aquifer (approximately 294 m deep). Inventory estimates, however, suggest that most of the perchlorate still resides above the perched intermediate aquifer. Longitudinal canyon transport has been significant (down canyon extent is approximately 4000 m). Perchlorate distributions and concentrations are highly correlated with nitrate (a co-contaminant), and we see no evidence of perchlorate degradation. Stochastic transport simulations suggest that peak perchlorate concentrations may reach the regional aquifer beneath the canyon in about 50 to 200 years.

This quad contains Copernicus and Eratosthenes Craters, both type localities of impact crater-related geologic units that formed the basis for the original lunar stratigraphic mapping by Shoemaker and others. Primary basemaps include a LO-IV photomosaic (60 m/px), Clementine UVVIS 5-band (100 m/px,) and NIR 6-band data (500 m/px), and UVVIS "standard" color ratios (R = 750/415 nm; G = 750/950 nm; B = 415/750 nm). These data are augmented by Clementine topographic data (1 km/px), derived optical maturity (OMAT), and other data for interpreting soil composition and physical properties. Major goals of this work are to demonstrate the integrated use of these photographic and color image data for geologic unit mapping and characterization. With the stratigraphy of Wilhelms (1987) as a starting point, we are using color and maturity information from Clementine to identify highland, volcanic, and crater-related units. One emphasis of this work is a local and regional characterization and refinement of the boundary between time-stratigraphic units of the Copernican and Eratosthenian Periods using optical maturity data. Preliminary mapping shows a substantially more diverse--both compositionally and temporally--and complex series of geologic units than have been previously mapped in the Copernicus Quadrangle. As a result of this work, we have identified optimal base maps, a mapping scale, and unit discrimination parameters that are appropriate for future geologic mapping by us and others across the Moon. Results will be compiled into a formal USGS SIM-series geologic map and described in a lunar mapping "handbook". This guide will include evaluations and recommendations for digital data acquisition and basemap construction, their relative utility for unit identification, characterization, and mapping, and useful tools and tips for future lunar geologic mappers.

Consequently, the NMED DOE Oversight Bureau initiated a study to determine if surface water loss in upper Pajarito Canyon is occurring within the PFZ. General hydrologic conditions include a perennial surface-water reach flowing west to east for approximately 2.4 km upstream of the PFZ. This reach is supplied by seeps and springs at about 2,740 m. Approximately 1.9 km downstream of PA-10.6 (surface water at the PFZ), the perennial springs Homestead, Starmer, and Bulldog discharge from horizontal fractures and/or surge beds at about 2,330 m. Recharge and discharge (water balance) measurements were nearly equivalent. From 1997 through 2003, hydrogeochemical parameters were obtained at PA-10.6 and the springs. Isotopic data suggest that Homestead and Starmer Springs are chemically and isotopically similar to the PA-10.6 waters. Bulldog Spring contains elevated concentrations of tritium and major ions, and is slightly enriched in delta D and delta 18O compared to water at PA-10.6, suggesting a different recharge source. Solutes produced from the Cerro Grande fire (May 2000) introduced tracers that show direct links between water at PA-10.6 and the downgradient springs. Subsequent monsoon flooding in the upper reach of Pajarito Canyon impacted water quality at PA-10.6. The combined data indicate that Homestead and Starmer Springs are supplied by waters that percolate into the PFZ, while Bulldog Spring is recharged independently of the PFZ.

The point infiltration estimates are based on a combination of techniques that include the use of the Richards equation, the chloride mass-balance method, and numerical modeling. The infiltration rates estimated with these techniques were extrapolated to uncharacterized parts of the study area using maps of environmental variables that are correlated with infiltration (such as topography, vegetation cover, and surficial geology and structure) and spatial algorithms implemented with GIS software that use the mapped variables. The map indicates that infiltration rates on mesas of the Pajarito Plateau are generally less than 2 mm/yr, except near faults, where infiltration rates may be several tens to hundreds of mm/yr. Infiltration rates at higher elevations in the Sierra de los Valles are typically greater than 25 mm/yr in mixed conifer areas and greater than 200 mm/yr in areas vegetated by aspen. An irregular transition zone with infiltration rates between 2 to 25 mm/yr exists near the western edge of the Pajarito Plateau adjacent to the Sierra de los Valles. This transition zone extends to lower elevations on the north-facing slopes of deeply incised canyons. Canyon-bottom infiltration rates are highly variable, ranging from several hundred mm/yr in canyons with large watersheds that have their headwaters in the Sierra de los Valles or in canyons that receive effluent from Laboratory operations, to several mm/yr in canyons that have their headwaters on the Pajarito Plateau but do not receive Laboratory effluent. The total net infiltration of approximately 10.6 X 106 m3/yr (8,600 acre-ft/yr) is consistent with estimates of the steady-state groundwater discharge to perennial streams in the study area, whereas the relative rates of infiltration within the study area are consistent with the distribution of natural and anthropogenic tracers such as tritium in perched and regional groundwaters.

Given the potential importance of dawsonite in the performance of a geologic carbon sequestration site, the stability of this mineral under physical-chemical conditions relevant to geologic storage and sequestration of carbon requires critical examination. Short-term experiments demonstrate that dawsonite is readily synthesized from gibbsite and kaolinite in concentrated NaHCO (sub 3) solutions. A series of hydrothermal fluid-mineral experiments using flexible cell hydrothermal apparatus (Dickson cells) were used to assess the long-term geochemistry and reactivity of dawsonite in more geologically reasonable solutions: moderately saline (0.05 molal) NaHCO (sub 3) solution with synthetic dawsonite at 50 and 75 degrees C, 200 bars; 1 molal NaHCO (sub 3) brine with Georgia kaolinite at 75 degrees C, 200 bars; and 1 molal NaCl brine with Georgia kaolinite at 75 degrees C, 200 bars. In this last experiment, the brine-mineral system was reacted at pressure and temperature for approximately 45 days to approach steady state, then injected with supercritical CO (sub 2) and allowed to react an additional 45 days. Reacted fluid was periodically sampled and analyzed for pH, SiO (sub 2) , Al, Na, Cl, and CO (sub 2) . Select samples were analyzed for colloidal particle-size-distribution and concentration. At temperature-pressure conditions expected for a carbon repository, dawsonite dissolves to yield 10-100 times more Al in NaHCO (sub 3) solution than predicted using existing thermodynamic data. Al-hydroxide colloids, a significant fraction of which are smaller than 0.45 microns, developed in solution. The colloidal fraction that is less than 0.45 microns, a commonly used filter size, accounts for at least some of this Al surplus. The Al surplus and the colloid abundance also appear to be related to the NaHCO (sub 3) concentration. A number of computer calculations of carbon repository integrity predict the formation of dawsonite in response to CO (sub 2) injection. Dissolution of dawsonite and formation of mobile Al hydroxide colloids can undermine the reliability of these predictions. The geochemical behavior of Al will be a key to determining the potential of dawsonite to sequester carbon.

The relationship between landscapes and tectonic inheritance, especially in regions of modern or ancient orogenic plateaus, is complex and depends on a number of factors. Influential parameters that exert the greatest control on surface topography include the type, strength, and geometry of inherited tectonic features, that in turn control observable topographic characteristics such as clustering, organization, flatness and grain orientation. Quantitative topographic analyses can help constrain the influence of inherited tectonics. Motivation for this approach comes from recent studies which show that: 1) topographic spectral power decreases systematically as the tectonic age of the underlying crust increases; 2) mean local relief, mean elevation, and thermo-chronologically-determined exhumation history vary systematically across major Paleozoic accretionary boundaries; 3) Neogene and ongoing rock-uplift is being driven by the creation of mantle buoyancy; and 4) a correlation exists between topography and such deep crustal features as mantle velocity structure, crustal thickness, and Precambrian crustal provinces. Here we present the results of a quantitative analysis of the topographic roughness, organization, flatness, clustering, grain and spectral power from a 30-arc-second topographic digital elevation model in an effort to evaluate the characteristic topographic signatures associated with the principal tectonic features in the Western U.S. Our preliminary results indicate that inherited features, defined on the basis of geologic and geophysical characteristics are also uniquely defined by topographic characteristics that reflect their tectonic development. In addition to the ancestral Sevier Plateau, our correlation also extends to tectonic features such as the major Precambrian crustal sutures, the Saint George and Jemez Lineaments, and the Cheyenne Belt. Finally, we explore the applicability of this technique to other orogenic plateaus such as in the Andes, Appalachians, and Pyrenees, and evaluate the tectonic-topographic correlations on several scales.

However, reactions simulated in laboratory experiments typically demonstrate rates that are much slower than those observed in the field. For this reason, it is necessary to conduct more reaction rate analyses in natural settings. Here, we present a preliminary study of geochemical reactions in the regional aquifer in the Pajarito Plateau near Los Alamos in northern New Mexico. Groundwater geochemistry shows marked evolution along flow paths, which we attribute to precipitation, dissolution, and ion exchange reactions. We particularly studied one flow path, and performed preliminary inverse mass balance modeling and calculated the mass transfer along segments of the flow path. Preliminary X-ray diffraction and Field Emission Gun Scanning Electron Microscopy of drill cuttings and outcrop samples were used to identify possible reactants and products. SEM data show that sediment grains are commonly covered with a coat of clay minerals about 5-8 microns thick. Our initial interpretations can be further refined by considering the mineralogy of the aquifer and saturation indices for the regional water properties. This study combines modeling with petrographic assessment to further knowledge and understanding of complex natural hydrologic systems.

Of particular concern in desert environments are deformation band faults, found in high porosity nonwelded tuffs in the PFS (Wilson et al., 2003). Deformation bands are narrow zones in which grain-size reduction, grain-boundary sliding, and pore collapse accommodate mm-cm displacements. In contrast to fractures, deformation bands reduce porosity and saturated permeability with respect to protolith material and are likely to increase fault-parallel unsaturated permeability in the vadose zone (Sigda et al., 1999). Where found in large enough concentrations, deformation bands may enhance vertical fluid flow to a degree that might raise concerns in areas where contaminants are present in the near-surface environment. Such areas of concern include Los Alamos National Laboratory, located in the Espanola Basin of the Rio Grande Rift (New Mexico). The Pajarito Fault (PF) is an active normal fault that bounds the west side of the Espanola Basin. Its many splays, extending 50 km along strike, dissect the Pleistocene Bandelier Tuff beneath the laboratory, while the main fault extends south through Bandelier National Monument. Associated with the PF are numerous small displacement faults, including fracture-based faults in welded tuffs and deformation bands in nonwelded tuffs. Extensive field mapping shows that the concentration of deformation bands is high adjacent to the PF (up to 250/50 m lateral distance), but decreases significantly ( approximately 10/50 m) within a kilometer of the fault. As nonwelded units of the Bandelier Tuff are extensive beneath the Pajarito Plateau, the high spatial density of deformation bands in the vicinity of faults with at least 12 m displacement could greatly enhance fluid flow into the subsurface.

More recently however, researchers have suggested that desert pavements are more dynamic. Healing experiments have shown that pavements reform over time scales of decades to centuries. Also, it has been suggested that in parts of the Mojave Desert above 400 m, all pavements were destroyed by latest Pleistocene vegetation advances, "re-setting" all desert pavement evolution in the Mojave above that elevation. In an effort to reconcile these seemingly disparate observations, we have developed an empirical-numerical model that captures the dual time-scale nature of desert pavement development and healing. To calibrate our model we conducted detailed geomorphic mapping, including pavement clast point-counting and integrated pavement-healing experiments from existing studies to capture the annual and millennial timescales. Our field work in Amargosa Valley, NV and CA highlights important differences in pavement evolution between sand-dominated and gravel-dominated parent materials. Our model treats desert pavement as a system that co-evolves with the underlying cumulic eolian epipedon over millennial and longer timescales. We emphasize the rate-controlling importance of development of the fine-grained inflationary eolian layer that is ubiquitous beneath well-developed desert pavements, and observe that "pavement-healing" from episodic disturbance occurs much more rapidly than the long-term development of the entire desert surface system. Furthermore, we conclude that the more well-developed the entire desert-surface system is, the more rapidly desert pavements are able to reorganize in response to transient disturbances.

BNM occupies the southern portion of the Pajarito Plateau whose canyons and mesas contain remnants of Ancestral Puebloan communities that flourished during the 12th to mid-16th centuries. In 2000, new geologic mapping commenced within and around the BNM and at present this mapping is being published as a series of 7.5-minute quadrangles by the New Mexico Bureau of Geology & Mineral Resources (Socorro, NM). Two quadrangles that cover significant portions of BNM (Frijoles and Bland) are now complete and their geology is the subject of this abstract. Eventually, it is anticipated that the geology of BNM will be published as a special map at 1:24,000. BNM is the type locality of the famous Bandelier Tuff, a voluminous series of ash flow tuff sheets (ignimbrites) that erupted from nearby Valles and Toledo Calderas at 1.25 Ma and 1.61 Ma, respectively. Rhyolitic fall deposits of El Cajete Pumice (50 to 60 ka), an eruption from within the Valles Caldera, overlie the Bandelier Tuff within most of the monument. The new mapping provides some insights into Puebloan culture. For example, there is a relation between the location of smaller Puebloan ruins and El Cajete deposits. Thus, it appears that ancestral Puebloan inhabitants grew crops on the pumice because of its sponge-like ability to store water. On the west side of BNM, the mapping has revealed that a large debris avalanche from Rabbit Mountain forms a tongue between outflow sheets 2 and 3 of the Upper Bandelier Tuff. Possibly, explosions from Valles Caldera caused collapse of the Rabbit Mountain dome between two ignimbrite eruptions. This deposit contains huge quantities of easily extractable obsidian blocks and was a mining site for ancestral Puebloans. The western part of the BNM is cut by the north-trending Pajarito fault system, the local active boundary fault of the Rio Grande Rift. The normal, down-to-the-east Pajarito Fault exhibits about 200 m of vertical displacement on the Upper Bandelier Tuff in the monument. Studies outside the monument indicate the fault system has had three Holocene surface rupturing earthquakes.

The Pleistocene (1.22 Myr old) Tshirege Member of the Bandelier Tuff (Qbt) provides an exceptional datum for studies of the PFS's Quaternary evolution. As the fault system cuts Qbt nearly end to end along its 50 km length, we use it to construct a composite fault displacement profile. Throw measured on displaced contacts of Qbt subunits or on the displaced top of the tuff shows that the PFS consists of numerous sections (8-12 km long) that each exhibit their maximum throw near their midpoint with throw dying out toward their ends. The cumulative displacement profile describes an elliptical shape typical of an isolated fault although the profile is somewhat saw-toothed with prominent throw deficits at locations where the main Pajarito Fault bends sharply. The style of deformation is particularly complex at these bends. Where slip is transferred from the N-striking Pajarito Fault (PF) to the NE-striking Santa Clara Canyon Fault (SCC), the PF forms a classic fault tip, where deformation is distributed across a broad zone of en echelon, small-displacement, synthetic and antithetic normal faults, fissures, and monoclinal folds. Short fault lengths and changes in sense of throw along strike are common. Two prominent antithetic faults relay slip to the SCC beyond the tip of the PF. Their maximum throw is greatest on the end closest to the PF, indicating fault interaction. Faults with opposing dips in the bend likely interlock, posing a geometrical barrier (sensu Aki, 1979) where ruptures either nucleate or terminate. That this portion of the PFS is strong fits with the slip deficit at this location and the paleoseismic event chronology, which demonstrates that the antithetic faults do not rupture every time the PF does. This bend in the fault system is also characterized by dilational normal faulting. Open, surficial fissures are common as are sediment-filled fissures, open framework breccias, and considerable fault plane topography in trench exposures of fault splays. These features are consistent with substantial dilation in the fault bend. This style of deformation enhances fluid flow and transport and must be factored into hydrogeologic investigations.

Federal and state regulations have been established to protect the environment from improper disposal of this waste water. Lawmakers in New Mexico have recognized the potential for re-use of produced water as noted by the recent passage of Senate Bill 313 in the 2004 New Mexico Legislature which increased the options for produced water disposal in the state. New Mexico House Bill 388 in 2002 established a tax credit for treating produced water and delivering it to the Pecos River. The National Pollution Discharge Elimination System (NPDES) permit program requires all discharges into surface waters be permitted by the EPA or approved state programs, to maintain water quality of the receiving waters. In addition to meeting the NPDES permit requirements for any direct discharge of produced waters, disposal of oil and gas waste water is also regulated by various state agencies. In New Mexico, disposition of produced water is regulated by the Oil and Gas Conservation Division (OCD) of the New Mexico Energy, Minerals and Natural Resources Department. The OCD is to regulate the "direct surface or subsurface disposal of the water, including disposition by use in drilling for or production of oil or gas, in road construction or maintenance or other construction, in the generation of electricity or in other industrial processes, in a manner that will afford reasonable protection against contamination of fresh water supplies designated by the state engineero". This modification of the previous regulation allows for re-use in various industries. Treatment options are now able to target specific industry requirements. For example, re-use of produced water in the oil and gas industry will require water quality that will not foul or interfere with drilling or fracing operations. In contrast, the electric power industry is concerned with total dissolved solids and chlorides due to scaling and corrosion. For use in the agricultural industry or direct surface disposal, nondegradation of the land and receiving waters is critical. This paper summarizes current state and federal regulations, along with specific industry criteria; providing treatment effluent limits as a function of the desired end-use.

Based on an experimental stratigraphy, a two-dimensional, fully heterogeneous, hydraulic conductivity map provides the basis for the evaluation of K* using numerical and analytic methods. For selected deposits, K* changes with support in an asymptotic fashion. A power-law exponent fitted is found to increase for deposits of higher variability. Up-scaling irregular hydrostratigraphic units indicates that the more stratified deposits have higher ln(K) variance and higher anisotropy ratio of K*. For all deposit types, the arithmetic mean appears a good approximation for the maximum principal component of K*. The minimum principal component of K* fluctuates between the harmonic and geometric mean. Based on the heterogeneity map, two geologic framework models (GFM) are developed. Four sets of flow experiments are conducted in each model. We found that reproducing the mean flow is the most sensitive to the choice of GFM and the boundary condition.

The Cosmonaut polynya first appeared in early May 1999 in the form of an ice-free embayment, transformed into an enclosed polynya on 5-9 July, and disappeared by late July, when the ice from the surrounding regions began to encircle the embayment. Except for the differences in ice concentrations, the time of appearance, size, and shape of the Cosmonaut polynya simulated by the model are in approximate agreement with the Special Sensor Microwave/Imager (SSM/I) observations. Between May and July 1999 the Cosmonaut Sea experienced two synoptic storms. Followed by the passage of the first storm on 12-19 June, there was a remarkable growth in the size of the embayment by 21 x 10 (super 3) km (super 2) . Associated with this, the sea surface temperature (SST) rose by 0.15 degrees C, the upward heat flux jumped from 5 to 94 W m (super -2) , and a net freshwater flux into the ocean increased by 2 cm d (super -1) . By running the model simulation with a 20% wind speed increase, it is demonstrated that the twofold increase in SST and upward heat flux increased the embayment area by 15 x 10 (super 3) km (super 2) and decreased the ice concentration by approximately 10% from the control run.

The LP spacecraft carried three Los Alamos built spectrometers--the gamma-ray, neutron, and alpha particle spectrometers--that were designed to measure the global composition of the lunar surface. While interpretation of data from these instruments is ongoing, some of the major results from these instruments are 1) the positive identification of enhanced hydrogen abundances at the lunar poles, which is thought to be in the form of water ice; 2) the full delineation of the composition asymmetry known as the Procellarum KREEP Terrane; 3) the first global maps of the major mineral forming elements; and 4) the identification of contemporary gas release events on the lunar nearside near Aristarchus and Kepler Craters. LP data have also been used in conjunction with other orbital and sample datasets for various data integration studies. We anticipate similar such studies will be increasingly used in the near future with upcoming missions to further enhance lunar exploration. LP data have also enabled the identification of specific locations on the Moon that are significantly different from the sites of the Apollo and Luna landings and could be attractive locations for future landing sites. In addition to the hydrogen anomalies at the poles, we have evidence for locations with evolved non-mare volcanism as well as large regions of mare basalt having compositions significantly different than any known samples. Finally, despite the success of the LP instruments, these data do have limitations in both spatial resolution and precision. We will discuss how improvements can be made for future measurements, both from orbit and on the surface.

Nowhere in the United States are these issues more apparent than in the San Joaquin Valley of California. A solid understanding of salinization processes at regional spatial and decadal time scales is required to evaluate the sustainability of irrigated agriculture. A hydro-salinity model was developed to integrate subsurface hydrology with reactive salt transport for a 1,400-km (super 2) study area in the San Joaquin Valley. The model was used to reconstruct historical changes in salt storage by irrigated agriculture over the past 60 years. We show that patterns in soil and groundwater salinity were caused by spatial variations in soil hydrology, the change from local groundwater to snowmelt water as the main irrigation water supply, and by occasional droughts. Gypsum dissolution was a critical component of the regional salt balance. Although results show that the total salt input and output were about equal for the past 20 years, the model also predicts salinization of the deeper aquifers, thereby questioning the sustainability of irrigated agriculture.

AN - 50276131; 2007-088268 AB - As on the Moon, much of the surface of Mars is covered with impact craters of various sizes and ages. Unlike on the Moon, Mars did and does have an atmosphere (albeit a dilute one), and the target areas of the impacts may have contained subsurface brines and salts in addition to ice (e.g., Knauth and Burt, 2002). The distinctive "rampart craters" of Mars have long been ascribed to the presence of an atmosphere and of volatile-rich targets. Nevertheless, the laminated sedimentary rocks of Mars (Malin and Edgett, 2000), have mainly been considered in terms of aqueous, aeolian, or volcanic deposition. We suggest that impact deposition cannot be excluded, especially given that the laminated, cross-bedded, sandy, salty sediments of the Opportunity landing site in Meridiani Planum more closely resemble distal impact surge deposits (i.e., deposits resulting from relatively low-density, ground-hugging, high-speed, heterogeneous flow), than they do any deposit produced by flowing or standing water (Burt and Knauth, 2004). Also, the uniformly shaped and sized Ni-rich hematitic spherules there more closely resemble accretionary lapilli or impact condensation spherules than they do typical concretions. If impact into a brine-, salt-, and ice-rich regolith, followed by later cold and dry weathering (including sulfide oxidation and wind deflation), produced all of the geologic features seen in Meridiani Planum, then impact might have produced many other finely layered, salt-encrusted sediments detected from orbit. Of particular interest are the Br-rich rock interiors and layered deposits discovered by the Spirit rover in Gusev Crater. Given that the basalt-littered surface there appears never to have been immersed in water, heterogeneous dispersal caused by impacts into a brine-soaked basaltic regolith should also should be considered for those deposits. By this hypothesis, the salty early hydrosphere of Mars would have dried up and frozen down (i.e., largely retreated into the regolith) BEFORE the end of major bombardment, allowing impact surge deposition of some (and conceivably all) of the laminated sediments exposed around the margins of the highlands. Concurrent and later sediment transport and deposition by explosive volcanism, brines, glaciers, and wind is not excluded.

In this paper we analyze Bouguer gravity data, crustal thickness variations, xenolith data, and seismic wave speed structure to argue that the Rio Grande Rift and southeastern Colorado Plateau is underlain by a low-density upper mantle province that does not trend along upper crustal tectonic boundaries but, rather, is correlated with regions of middle to late Tertiary magmatism. We model uppermost mantle density contrasts using Bouguer gravity along five parallel profiles across the Colorado Plateau and validate our models by converting modeled density contrasts to seismic velocity variations for comparison with regional seismic data, as well as comparing modeled densities to calculated densities from xenoliths. We find that upper crustal features and crustal thickness variations do not explain long-wavelength (>200 km) variations in Bouguer gravity across the Colorado Plateau-Rio Grande Rift. A large 200-440 km wide region of low uppermost mantle density is modeled beneath the eastern Colorado Plateau margin, Jemez Lineament, Rio Grande Rift, and parts of the westernmost Great Plains. This region has a density contrast of -90 to -30 kg/m (super 3) relative to the adjacent Colorado Plateau and Great Plains provinces and coincides with previously imaged regions of low upper mantle seismic velocities. In situ densities inferred from xenolith data in the Colorado Plateau support the modeled upper mantle density variations and support the idea that the eastern and western margins of the plateau have been significantly modified by metasomatism. We suggest that the region of low upper mantle density likely reflects some combination of temperature variations, partial melt contents, and compositional variations related to Tertiary magmatic activity and/or thinned lithosphere. The relationship of this zone of modified upper mantle to extension in the Rio Grande rift remains enigmatic, however, particularly given the lack of spatial correlation between the trends of upper mantle structures and surficial extensional structures.

The important role of this large family of enzymes in controlling cellular functions and developmental processes along with their crystallizability has made them good candidates for structural studies. We recently determined the structure of an evolved version of an NDP kinase from Pyrobaculum aerophilum, an extreme thermophile. This NDP kinase has similarity to the 42 other NDP kinases deposited in the Protein Data Bank (PDB) but differs significantly in sequence, structure, and biophysical properties. The P. aerophilum NDP kinase sequence contains two unique segments not present in other NDP kinases, comprising residues 66-100 and 156-165. We show that deletion mutants of the P. aerophilum NDP kinase lacking either or both of these inserts have an altered substrate specificity, allowing dGTP as the phosphate donor. A structural analysis of the evolved NDP kinase in conjunction with mutagenesis experiments suggests that the substrate specificity of the P. aerophilum NDP kinase is related to the presence of these two inserts.

Actinide oxides and nitrides are particularly interesting, although molecular parallels have only existed for the former. In her Perspective, Burns discusses results reported in the same issue by Evans et al. in which the first simple molecular nitrides of uranium were prepared. The achievement of this key synthetic target will offer fresh opportunities for exploring chemical bonding and novel reactivity.

AN - 68643977; 16197630 AB - Laser-induced breakdown spectroscopy (LIBS) measurements are typically carried out using pulses (<20 ns, >50 mJ) from a flashlamp-pumped electro-optically Q-switched Nd:YAG laser (EO-laser) or excimer laser. Here we report LIBS analyses of solids using an acousto-optically Q-switched Nd:YAG laser (AO-laser) producing 150 ns pulses of lower energy (10 mJ) at repetition rates up to 6 kHz. The high repetition rate allows increased spatial or depth sampling over a given time period compared to the EO-laser. Results of AO-laser based LIBS analysis of (1) steels, (2) soils, and (3) surface stains and dusts are described. Detection limits for Cr, Cu, Mn, Ni, and Si in steel ranged from 0.11 to 0.24% using a commercial polychromator-based detection system with limits 4--30 times lower achieved using a laboratory-based detection system. The minimum detectable masses of Ba, Cr, Mn, and Sr on a metal surface were estimated with 1.2 pg/shot achieved for Sr. Detection limits for Ba and Sr in soil were 296 and 52 ppm, respectively. The temperatures, spectra, and emission decay curves from plasmas generated by the AO- and EO-lasers are compared and some characteristics of particles ablated by the AO-laser are described.

Application to Improving the Folding and Solubility of Recalcitrant Proteins from Mycobacterium tuberculosis AN - 19441188; 6873228 AB - We have improved our green fluorescent protein (GFP) folding reporter technology [Waldo et al., (1999) Nat. Biotechnol. 17, 691-695] to evolve recalcitrant proteins from Mycobacterium tuberculosis. The target protein is inserted into the scaffolding of the GFP, eliminating false-positive artifacts caused by expression of truncated protein variants from internal cryptic ribosome binding sites in the target RNA. In parallel, we have developed a new quantitative fluorescent protein tagging and detection system based on micro-domains of GFP. This split-GFP system, which works both in vivo and in vitro, is amenable to high-throughput assays of protein expression and solubility [Cabantous et al., (2005) Nat. Biotechnol. 23, 102-107]. Together, the GFP folding reporter and split-GFP technologies offer a comprehensive system for manipulating and improving protein folding and solubility.

To better understand this organism and to facilitate assembly of its sequence, three whole-genome restriction endonuclease maps (XbaI, NheI, and HindIII) of R. rubrum strain ATCC 11170 were created by optical mapping. Optical mapping is a system for creating whole-genome ordered restriction endonuclease maps from randomly sheared genomic DNA molecules extracted from cells. During the sequence finishing process, all three optical maps confirmed a putative error in sequence assembly, while the HindIII map acted as a scaffold for high-resolution alignment with sequence contigs spanning the whole genome. In addition to highlighting optical mapping's role in the assembly and confirmation of genome sequence, this work underscores the unique niche in resolution occupied by the optical mapping system. With a resolution ranging from 6.5 kb (previously published) to 45 kb (reported here), optical mapping advances a "molecular cytogenetics" approach to solving problems in genomic analysis.

The initial survey used 16S rRNA gene primers to detect Francisella species and related organisms by PCR amplification of DNA extracts from environmental samples. This analysis indicated that sequences related to Francisella were present in one water and seven soil samples. This is the first report of the detection of Francisella-related species in soil samples by DNA-based methods. Cloning and sequencing of PCR products indicated the presence of a wide variety of Francisella-related species. Sequences from two soil samples were 99.9% similar to previously reported sequences from F. tularensis isolates and may represent new subspecies. Additional analyses with primer sets developed for detection and differentiation of F. tularensis subspecies support the finding of very close relatives to known F. tularensis strains in some samples. While the pathogenicity of these organisms is unknown, they have the potential to be detected in F. tularensis-specific assays. Similarly, a potential new subspecies of Francisella philomiragia was identified. The majority of sequences obtained, while more similar to those of Francisella than to any other genus, were phylogenetically distinct from known species and formed several new clades potentially representing new species or genera. The results of this study revise our understanding of the diversity and distribution of Francisella and have implications for tularemia epidemiology and our ability to detect bioterrorist activities.

AN - 68518110; 16123304 AB - The complexity of soil bacterial communities has thus far confounded effective measurement. However, with improved analytical methods, we show that the abundance distribution and total diversity can be deciphered. Reanalysis of reassociation kinetics for bacterial community DNA from pristine and metal-polluted soils showed that a power law best described the abundance distributions. More than one million distinct genomes occurred in the pristine soil, exceeding previous estimates by two orders of magnitude. Metal pollution reduced diversity more than 99.9%, revealing the highly toxic effect of metal contamination, especially for rare taxa. JF - Science (New York, N.Y.)

AN - 68429860; 16039012 AB - During numerical simulation of air flow in the vadose zone, it was noticed that a small sinusoidal pressure would cause a gradual one-way migration of the pore gas. This was found to be a physical phenomenon, not a numerical artifact of the finite element simulation. The one-way migration occurs because the atmospheric pressure, and hence the air density, is slightly greater when air is flowing into the ground than when air is flowing out of the ground. A simple analytic theory of the phenomenon is presented, together with analytic calculations using actual barometric pressure data. In soil of one Darcy permeability, the one-way migration is of the order of a few tenths of a meter per year for either plane flow from ground surface or for radial flow from an open borehole. The migration is sufficiently small that it will have no practical consequences in most circumstances; however, investigators who conduct detailed numerical modeling should recognize that this phenomenon is not a numerical artifact in an apparently linear system.

AN - 68029128; 16012083 AB - A mathematical model has been developed to estimate service lives of air-purifying respirator cartridges that remove gases reactively from flowing air. Most gases, because of their high volatility and low polarizability, are not effectively removed by physical adsorption on activated carbon. Models previously developed for toxic organic vapors cannot estimate service lives of cartridges for toxic gases. Often, an activated carbon is impregnated with a chemical to enhance gas removal by chemical reaction(s). The kinds of reactions, types and amounts of impregnants, and effects of the presence of water vary; therefore, the model requires user inputs of gas capacity and water effect parameters. Ideally, these should be available from manufacturers of the cartridges. If they are not, they can be extracted from measured breakthrough times using this model. The key to this model is the observation that adsorption rates of gases can be adequately quantified by the same correlations that have been reported for organic vapors.

The cone at the hawaiitic Lathrop Wells volcano, southern Nevada, contains deposits that are consistent with these processes during early cone-building phases; these early deposits are composed mainly of coarse lapilli and fluidal bombs and are partially welded, indicating relatively little cooling during flight. However, the bulk of the cone is composed of relatively fine-grained (ash and lapilli) planar beds with no welding, even within a few tens of meters of the vent. This facies is consistent with deposition by direct fallout from sustained eruption columns of relatively well-fragmented material, primarily mantling cone slopes and with a lesser degree of avalanching than is commonly assumed. A laterally extensive fallout deposit (as much as 20 km from the vent) is inferred to have formed contemporaneously with these later cone deposits. This additional mechanism for construction of scoria cones may also be important at other locations, particularly where the magmas are relatively high in volatile content and where conditions promote the formation of abundant microlites in the rising mafic magma.

The dated sediments were collected from the banks of tie channels along the Lower Mississippi River, the Fly River in Papua New Guinea, and Birch Creek along the Yukon River in Alaska. Tie channels connect the oxbow lakes to the main stem river and allow the exchange of water and suspended sediment between the two. The banks consist of fine sand and sandy silt beds interlayered with silt and clay. OSL samples were collected both horizontally from exposed banks and vertically by coring through levee crests; sample collection was targeted at beds containing appreciable quantities of fine sand. OSL ages were determined using single-grain or in some cases single-aliquot techniques and dose distribution analysis. Samples were first collected along the Lower Mississippi tie channel to compare OSL dates with historical data sources and test the applicability of OSL in these settings; the OSL dates agreed closely with historical data. In all three river systems, OSL dating allowed the determination of vertical accretion rates, tie channel advancement rates, and oxbow lake ages. In Papua New Guinea, OSL sampling also provides an estimate of lateral migration rates of the Fly River and allows a comparison of modern mine-influenced deposition rates with natural background rates over the last 1000 years. Results from Papua New Guinea and the Mississippi River suggest that the advancement rate of tie channels responds directly to changes in the sediment load of the main stem river.

In Treatment 1, 280 Mg ha (super -1) of FGD was incorporated into the graded spoil to a depth of 20 cm. In Treatment 2, 280 Mg ha (super -1) of FGD and 112 Mg ha (super -1) of yard waste compost were incorporated into the graded spoil (FGDC). In Treatment 3, 112 Mg ha (super -1) of limestone was incorporated into the graded spoil and was covered with 20 cm of graded borrowed topsoil (BTS). Six cores and six bulk soil samples were obtained from each treatment for the 0- to 10-cm depth in summer 2002. From the 10- to 20-cm depth, only bulk soil samples were obtained. Bulk and core soil samples were also collected from an unreclaimed spoil (SP) and a nearby unmined soil (UMS). Among the three reclamation treatments, BTS showed better soil quality with higher soil organic C (28.5 Mg ha (super -1) ), water-stable aggregation (556 g kg (super -1) ), and mean weight diameter (3.2 mm) of aggregates than FGDC or FGD treatments. The FGDC had higher soil inorganic and organic C than FGD. However, saturated hydraulic conductivity (K (sub s) ), cumulative infiltration (I), infiltration rates at 5 min (i (sub 5) ) and 2.5 h (i (sub c) ), and soil pH were similar among three treatments. Among treatments and controls, soil bulk density (rho (sub b) ) was lower for FGD, FGDC, and UMS than BTS and SP; and water-stable aggregation and mean weight diameter of the aggregates was higher for UMS and BTS than FGDC, FGD, and SP for both depths. The I and i (sub c) were similar among UMS and treatments. Reclamation improved the soil quality with higher soil pH (7) and inorganic and soil organic C than in the SP. With respect to FGD, the soil organic C in FGDC increased at the rate of 0.64 Mg ha (super -1) yr (super -1) for the 0- to 10-cm depth. Overall, BTS was the best reclamation treatment. However, if topsoil is unavailable or transport is expensive, FGDC can be used as an effective reclamation material.

A high explosive machining facility discharged effluent containing these chemicals to the canyon from 1951 to 1996. The connectivity between alluvial groundwater, surface water, and sediment was specifically addressed to understand the distributions and dynamics of Ba and RDX in the alluvial system. Surface water, groundwater, and sediment were characterized by conducting hydrologic measurements, geomorphic mapping, and collecting samples. Barium and RDX in sediment preferentially reside in fine-grained deposits that represent the suspended load redeposited on floodplains following channel scour. However, RDX and Ba show markedly different behaviors in surface water and alluvial groundwater because of contrasting geochemical characteristics and transport mechanisms. Barium precipitates in sediments as barite and witherite and readily sorbs to sediment minerals. Therefore, sediment transport is an important control on its distribution in the canyon. In contrast, RDX appears to occur predominantly in the dissolved phase, behaves conservatively, and is most significant in groundwater. There is a strong correlation between RDX concentrations in water and the saturated thickness of the alluvial aquifer. During prolonged wet periods, the alluvial aquifer enlarges, causing more RDX to be mobilized within the alluvial system. Subsurface processes in the alluvial aquifer are therefore most important in controlling present RDX transport, whereas surface processes associated with floods are most important in controlling Ba transport.

Subsurface pathway performance or risk assessments at Los Alamos require characterizing the unsaturated hydrologic properties of the Bandelier Tuff. The objective of this study was to analyze available unsaturated zone matrix hydrologic properties data for the Bandelier Tuff from the Los Alamos area for the purpose of developing estimates of properties and parameters for modeling vadose zone flow and transport. The hydrologic properties bulk density, saturated hydraulic conductivity, and the van Genuchten equation parameters, residual and saturated water contents, alpha , and n, were measured or estimated from measured data. A nonparametric statistical approach was used because of the small sample size leading to nonnormal distribution of the samples. The following differences were investigated: (i) between boreholes for a given unit within a site and (ii) between sites for a given unit. Results for borehole analyses within a location found that properties were different at one location and could be combined at another. The testing between locations found that samples could be readily combined. Linear correlation analyses of the one geologic unit that was the most consistent across the Los Alamos site found that there was essentially no relationship between matrix hydrologic properties or parameters to allow surrogate properties to be used for prediction. This preliminary analysis indicated that investigations at LANL will require more detailed sampling on a site-specific basis because properties cannot be transferred or estimated with any confidence.

Risk assessments increasingly must focus on multisite, multipathway analyses as opposed to single-site, single pathway analyses. Such assessments can be particularly challenging when contaminants are widely dispersed in complex topography. Here we highlight how a set of contaminated sites situated within complex topography can be effectively prioritized relative to vulnerability of contaminant transport from surface and subsurface flows. We used a distributed hydrologic model, SPLASH, to assess the lateral flows of surface and subsurface water following the simulation of a 100-year precipitation event, which could correspond to an intense thunderstorm. Our case study was conducted in the North Ancho watershed of Los Alamos National Laboratory, in northern New Mexico, USA, an area with widely dispersed contaminants and diverse topography. Simulated surface flows generally exceeded subsurface flows by more than four orders of magnitude, indicating the relative importance of potential redistribution of contaminants by surface flows for this type of precipitation event. For the 18 potential contaminant release sites investigated, the maximum surface flow varied by more than an order of magnitude across the sites. Half of the sites had surface flows <25% of the maximum surface flow for a site, allowing for prioritization of those sites with the greatest vulnerability. Our results highlight how risks of contaminant transport can be effectively assessed in complex topography using distributed hydrologic modeling.

Geologic investigations were undertaken as part of a plateau-wide hydrogeological investigation to develop conceptual models of the groundwater system as a framework for numerical simulations of groundwater flow. The Pajarito Plateau is located in the western part of the Espanola basin where rocks of the Jemez and Cerros del Rio volcanic fields overlie and interfinger with Neogene basin-fill sedimentary rocks. The vadose zone is about 200 m (600 ft) thick beneath mesas on the east side of the plateau and more than 375 m (1245 ft) thick on the west side. Groundwater occurs as shallow groundwater in canyon-floor alluvium, moderately deep groundwater perched in bedrock units of the vadose zone, and groundwater associated with the regional saturated zone. The most productive rocks of the regional aquifer occur in a westward-thickening wedge of coarse-grained, Miocene and Pliocene volcaniclastic rocks derived from the Jemez volcanic field. Eastern aquifer rocks consist of fine-grained, somewhat less productive Miocene sedimentary deposits derived from highland sources to the east and north. Intermediate and mafic lavas interbedded with the Miocene and Pliocene sedimentary deposits are components of the regional aquifer locally. The hydrogeology of the Pajarito Plateau is probably typical of groundwater systems along the margins of the Rio Grande rift where arid to semiarid, sediment-filled basins receive most of their recharge from adjacent mountainous areas.

To achieve this for a semiarid region, we studied a landfill cover containing a gravel layer, an evapotranspiration (ET) cover, in the field for 7 yr. We measured total water balance at 6-h intervals for this landfill cover design in four 1.0- by 10.0-m plots with downhill slopes of 5, 10, 15, and 25%. During the 7 yr of the field study, runoff accounted for 1.4 to 3.8% of the precipitation losses on these unvegetated landfill cover designs, whereas similar values for evaporation ranged from 88 to 95%. Evaporation usually increased with increases in slope in our field plots; for example, the ET Cover at slopes of 5 and 15% displayed 274 and 296 cm of evaporation, respectively. Interflow and seepage usually decreased with increasing slope; for example, as slope increased from 10 to 25%, interflow decreased from 18.4 to 8.8 cm. Seepage consisted of up to 1.7% of the precipitation on the ET cover, showing a maximum value of 5.3 cm on the ET cover with the slope of 5%.

Drainage across LANL is generally from west to east and feeds into the Rio Grande along the eastern margin of the plateau. Canyons with headwaters in the Sierra de los Valles west of the plateau support more flow and are wetter than canyons with headwaters on the plateau. Los Alamos Canyon, one of the wetter canyons, has extensive clay alteration to depths >30 m in the subcanyon vadose zone. Mortandad Canyon, one of the drier canyons, has less clay alteration. Hydraulic property data for the Otowi Member of the Bandelier Tuff, one of the most widespread lithologies of the plateau, indicate that zones of high clay abundance have hydraulic transmissivities (K (sub sat) ) one to two orders of magnitude lower than less altered tuff ( approximately 10 (super -4) vs. 10 (super -2) to 10 (super -3) cm/s). Occurrences of halloysite, and perhaps kaolinite, indicate zones where the water/rock ratio is or has been high within the vadose zone. Gravimetric water content data collected at 110 degrees C from vadose zone rocks with low to moderate clay content provide water abundance data for matrix flow calculations. These data may be in error by up to 5 to 16% because some of the water measured is actually held in clay interlayers rather than in pore spaces; such errors are minor but should be considered in the use of gravimetric moisture data. The use of electrical methods to explore for vadose wet zones is valid on the Pajarito Plateau as long as the results are treated broadly, with the understanding that some intervals of high conductivity are not entirely related to either movable water content or clay abundance.

Using 12 tipping-bucket rain gauges within a 40-ha pinon [Pinus edulis Engelm)-juniper (Juniperus monosperma (Engelm.) Sarg.] woodland in New Mexico, we measured rainfall erosivity (EI30) and associated precipitation and erosion metrics for 14 convective thunderstorms. Spatial variability in EI30 had a median CV across storms of 22% (range: 9-73%), exceeded the median CV for rainfall depth (15%, range: 5-26%), and varied by up to a factor of five (5-25 N h (super -1) ) within 300 m. EI (sub 30) was better correlated with sediment yield measured in <0.1-ha microwatersheds (r (super 2) = 0.67; p<0.001) than rainfall depth (r (super 2) = 0.43; p<0.001). Our results highlight the potential importance for erosion related assessments of spatial variability in erosivity, which can be as great or greater than spatial variability in rainfall depth. The spatial variability in rainfall erosivity that we document here is relevant to erosion and contaminant transport issues near Los Alamos National Laboratory and may be applicable to other extensive semiarid areas.

In 1961, a 2.5- to 20-cm-thick asphalt cap and gravel and clay cover was constructed to isolate contamination of surface soils associated with subcritical hydronuclear safety experiments conducted at TA-49 between 1959 and 1961. The asphalt cap remained in place for 37 yr until 1998 when it was replaced with an ET cover. Cracks and subsidence features in the asphalt cap were periodically filled during that time. The thickness of the ET cover is 2.1 m at its center, tapering to zero thickness at its edges. The ET cover is instrumented with three neutron logging access tubes, and four time domain reflectometry (TDR) probes, and covered by a galvanized steel mesh bio-intrusion layer. Soil moisture monitoring was conducted immediately after the removal of the asphalt cap in 1998, and continuously since 1999 within the ET cover, providing a unique comparison of the performance of these cap and cover types at a semiarid site. Soil moisture monitoring results indicate that the soils within and beneath the ET cover have been drying since its installation, and infiltration of precipitation and snowmelt has been minimized. The replacement of the asphalt cap with the ET cover has significantly decreased shallow subsurface moisture contents. With continued growth of vegetation and increased transpiration, the site should continue its return to native conditions where net infiltration and associated groundwater recharge rates are <7 mm yr-1.

The emissive debris trail from the fireball extended from 56 to 18 km altitude and remained detectable at IR wavelengths for > 1 hour. Two distinct disintegration features along the path at 32 km and 25 km altitude were observed. The original solar orbit of the meteoroid was similar to near-Earth asteroids of the Aten group. The total energy was estimated as equivalent to approximately 13 kilotons of TNT corresponding with a mass of (0.65 + or - 0.05) X 10 (super 6) kg. Some 7.5 hr after the satellite observation, an anomalous cloud of mu m-sized particles and non-spherical solid aerosols ((1.1 + or - 0.3) X 10 (super 6) kg) occurred related to the fireball, and details are presented of particle sizes and their potential range The simplest match to the observed range and distribution of particles is olivine and pyroxene for effective radii of approximately 0.3 to approximately 1.1 mu m.

Implications for climate forcing of such disintegration products and aerosols are discussed.

By use of electrospray ionization of whole oil samples, all neutral nitrogen compounds and acid NSO compounds, from approximately 300 to 900 Da, are selectively characterized and assigned unambiguous molecular formulae. Several methods of data visualization reveal changes in the relative abundances of these compounds with increasing degradation. Evidence for selective biodegradation is observed in all compound classes. NSO compounds associated with long alkyl side chains are removed, regardless of the NSO core, under conditions associated with moderate (saturated biomarkers unaffected) to severe biodegradation. Some compound series, such as O (sub 1) , O (sub 3) , and SO (sub 3-9) , are mineralized under conditions of mild biodegradation (n-alkanes, isoprenoids altered but still present). Changes in the Z-series (hydrogen deficiency) and alkyl distributions of the O (sub 2) species result from simultaneous microbial degradation and generation. Acyclic fatty acids decrease, whereas Z=-10 O (sub 2) species, which correspond to five-ring naphthenic (hopanoic) acids, increase in relative abundance during early stages of biodegradation. Monocyclic (Z=-2) O (sub 2) are enriched initially, and then decrease during advanced stages of biodegradation. O (sub 2) species corresponding to di-, tri-, and tetra-cyclic naphthenic acids (Z=-4, -6 and -8) are preferentially produced during these advanced stages. The ratio of acyclic to 2-4 ring cyclic O (sub 2) -species provides a new parameter to define the degree of biodegradation.

However, direct measurements of gas exchange in common environmental conditions do not always reveal size-related differences, even when there is a distinct size-related trend in delta super(13)C of the very foliage used for the gas exchange measurements. Since delta super(13)C of foliage predominately reflects gas exchange during spring when carbon is incorporated into leaf cellulose, this implies that gas exchange differences in different-sized trees are most likely to occur in favorable environmental conditions during spring. If gas exchange differs with tree size during wet but not dry conditions, then this further implies that environmental sensitivity of leaf gas exchange varies as a function of tree size. These implications are consistent with theoretical relationships among height, hydraulic conductance and gas exchange. We investigated the environmental sensitivity of gas exchange in different-sized Douglas-fir (Pseudotsuga menziesii) via a detailed process model that specifically incorporates size-related hydraulic conductance [soil-plant-atmosphere (SPA)], and empirical measurements from both wet and dry periods. SPA predicted, and the empirical measurements verified, that differences in gas exchange associated with tree size are greatest in wet and mild environmental conditions and minimal during drought. The results support the hypothesis that annual net carbon assimilation and transpiration of trees are limited by hydraulic capacity as tree size increases, even though at particular points in time there may be no difference in gas exchange between different-sized trees. Maximum net ecosystem exchange occurs in spring in Pacific Northwest forests; therefore, the presence of hydraulic limitations during this period may play a large role in carbon uptake differences with stand-age. The results also imply that the impacts of climate change on the growth and physiology of forest trees will vary depending on the age and size of the forest.

The importance of wet weather flow (WWF) pollutant loads is well known, but in semi-arid regions where urbanization is significant the pollutant load in dry weather flow (DWF) may also be important. This research compares the relative contributions of potential contaminants discharged in DWF and WWF from the Ballona Creek Watershed in Los Angeles, California. Models to predict DWF and WWF loads of total suspended solids, biochemical oxygen demand, nitrate-nitrogen, nitrite-nitrogen, ammonia-nitrogen, total Kjeldahl nitrogen, and total phosphorus from the Ballona Creek Watershed for six water years dating from 1991 to 1996 were developed. The contaminants studied were selected based on data availability and their potential importance in the degradation of Ballona Creek and Santa Monica Bay beneficial uses. Wet weather flow was found to contribute approximately 75 percent to 90 percent of the total annual flow volume discharged by the Ballona Creek Watershed. Pollutant loads are also predominantly due to WWF, but during the dry season, DWF is a more significant contributor. Wet weather flow accounts for 67 to 98 percent of the annual load of the constituents studied. During the dry season, however, the portion attributable to DWF increases to greater than 40 percent for all constituents except biochemical oxygen demand and total suspended solids. When individual catchments within the watershed are considered, the DWF pollutant load from the largest catchment is similar to the WWF pollutant load in two other major catchments. This research indicates WWF is the most significant source of nonpoint source pollution load on an annual basis, but management of the effects of the nonpoint source pollutant load should consider the seasonal importance of DWF.

Finite strain analysis of current data allowed us to determine the elastic moduli and their pressure derivatives independent of the pressure measurement. The results are K (sub S) = 253(2) GPa, G = 173(1) GPa, K (sub S) /P = 4.4(1) and G/P = 2.0(1). The temperature derivatives of the bulk and shear moduli were tightly constrained from acoustic velocity measurements, yielding K (sub S) /T = -0.021(2) GPa/K and G/T = -0.028(2) GPa/K. P and S wave velocities and density profiles for a pyrolite compositional model consisting of magnesium silicate perovskite and magnesiowustite are calculated at lower mantle depths along a 1600 K adiabatic geotherm, the results agree with those of seismic model PREM within 0.5, 0.5 and 0.3%, respectively, from 800 to approximately 2600 km. The effect of Fe and Mg partitioning between magnesium silicate perovskite and magnesiowustite on the calculated velocities and density is negligibly small compared to the effects of composition and temperature. Simultaneous constraints from P and S wave velocities and density support for a homogeneous lower mantle with pyrolitic composition.

AN - 19707749; 8249493 AB - One of the most general types of stress experienced by plants is water-limitation, which becomes particularly pronounced during periods of drought. We evaluated fluctuating asymmetry (FA) in Quercus undulata leaves for two subsequent dry years: 2001, when precipitation was 25% below average, and 2002, when precipitation was 65% below average, from a plot receiving ambient water and one in which water was excluded. In the first and less severe drought year, ambient-water trees had a slightly higher index of FA than the water-exclusion trees, contrary to expectations. However, in the second and much more extreme drought year, water-exclusion trees exhibited greater FA as expected, but in additional observations water-supplement trees exhibited by far the greatest amount of FA, contrary to expected. Further data on plant water potential confirmed that degree of plant stress corresponded to plot treatments: water exclusion>ambient water>water supplement. Stable carbon isotope ratios indicated that trees on the water-supplement plots were less stressed than ambient-water and water-exclusion trees, and leaf size was much greater for water-supplement trees than ambient-water or water-exclusion trees. We hypothesize that the complexity of the results could be due to the confounding effects of relative vs. absolute stress.

8250146 AB - The feed-forward-loop (FFL), a network motif in genetic regulatory networks, involves two transcription factors (TFs): one regulates the expression of the second, and both TFs regulate the expression of an effector gene. Analysis of FFL design principles has been initiated, but the functional significance of the FFL is still unclear. In theoretical studies so far, the TFs are assumed to interact with different signals, which is common. However, we have found examples of FFLs in Escherichia coli in which both TFs interact with the same signal. These examples belong to the type 2 incoherent class of FFLs, in which each TF acts exclusively as a repressor of transcription. Here, we analyze mathematical models of this class of circuits, examining a comprehensive array of subclasses that differ in the way a signal modulates the activities of the TFs. Through parameter variation, we characterize statistically how input/output (I/O) behavior and temporal responsiveness are predicted to depend on the wiring of signal interactions in a circuit. We find that circuits can exhibit any of 13 qualitatively distinct steady-state I/O patterns, including inducible and repressible patterns. Some subclasses exhibit as many as six patterns. Transient pulses are also possible, and the response of a circuit to a signal may be either faster or slower than that of a gene circuit in which there is only one TF. Our results provide a catalog of functions for a class of FFL circuits, whose subclasses have different breadths of possible behaviors and different typical behaviors.

A transducer fit with a quarter-wave matching layer, locally drives a cavity of width one-half wavelength. Particles within the cavity experience a time-averaged drift force that transports them to a nodal position. Present research investigates an acoustic particle-positioning device where the acoustic excitation is generated by the entire structure, as opposed to a localized transducer. The lowest-order structural modes of a long cylindrical glass tube driven by a piezoceramic with a line contact are tuned, via material properties and aspect ratio, to match resonant modes of the fluid-filled cavity. The cylindrical geometry eliminates the need for accurate alignment of a transducer/reflector system, in contrast to the case of planar or confocal fields. Experiments show that the lower energy density in the cavity, brought about through excitation of the whole cylindrical tube, results in reduced cavitation, convection, and thermal gradients. The effects of excitation and material parameters on concentration quality are theoretically evaluated, using two-dimensional elastodynamic equations describing the fluid-filled cylindrical shell with a line excitation.

Because safety practices specify both behavioral norms & technical standards, they provide an opportunity to better understand the relationships between the organizational & epistemic aspects of scientific culture. This paper presents a case study of a 'pulsed-power' facility at the US Los Alamos National Laboratory, where electrical hazards are a major concern. Drawing on work by Mary Douglas & others, I show how safety in the pulsed-power laboratory can be understood in terms of concepts of order & pollution. In particular, I argue that the laboratory is a cultural setting that generates both material & social order in science. The concept of 'traceability' -- the ideal of being able to trace visual & logical connections between system components -- is the central metaphor for material order in this setting. This metaphor is enacted in the design of pulsed-power systems & through various safety procedures that function as rituals. These rituals, & the concept of traceability itself, also contribute to social order by helping to shape norms of conduct in the laboratory, which in turn structure relationships between the laboratory work group & the larger institution. 61 References.

In many cases, high severity burns have caused dramatic increases in runoff and sediment yield from burned watersheds. This paper describes the potential and limitations of the HEC6T sediment transport model to describe changes in channel scour and deposition following the Cerro Grande fire near Los Alamos, New Mexico. Following the fire, Pueblo Canyon, near Los Alamos, was subject to a peak flow two orders of magnitudes higher than any discharge in the 7-year period of record, and twice the initial post-fire estimate of the 100-year event. HEC6T requires that the limits of scour and deposition on a cross-section be specified prior to application. This was achieved by using geomorphologic principles, predicted post-burn hydrology and long-term estimates of channel change derived from air photos, to estimate post-fire channel widths. Because significant quantities of silt and clay were present in the runoff, erosion shear stress and erosion rate parameters for cohesive sediments had to be obtained experimentally. After a sensitivity analysis, an optimization routine was used to estimate the optimal model parameter values for sensitive parameters. HEC6T was able to accurately model the change in cumulative sediment volume change derived from Airborne Laser Swath Mapping (ALSM, often called Lidar) taken before and after the large post-fire event. One discrepancy between the HEC6T model prediction and the ALSM-estimated change was that the ALSM-estimated change showed the greatest amount of deposition in a portion of the canyon with increasing slope, which the HEC6T model did not predict. Any sediment transport model will predict increased sediment transport capacity with increasing energy slope, so that it was considered to be beyond the capability of any sediment transport model to predict this deposition. Therefore, HEC6T simulated the overall changes in scour and deposition within reasonable expectation of the capabilities of physically-based sediment transport modeling indicating that it is capable of modeling sediment transport in ephemeral channels following wildfire.

A ground-based infrasound array was deployed to Wendover, Nevada, to measure the "hypersonic boom" from the reentry, since the expected initial reentry speed of the body was about 11 km/sec. Due to the complete failure of its dual parachute system, we had a unique opportunity to assess the degree of reliability of our previously developed relations for natural meteors and bolides to analyze this well-characterized manmade body. At approximately 20-50 km from the nominal trajectory, we succeeded in recording over two minutes of infrasonic signals from Genesis. Here we report on subsequent analyses of these infrasonic data, including an assessment of the expected entry characteristics on the basis of a bolide/meteor/fireball entry model specifically adapted to modeling reentering manmade objects. From these simulations, we were able to evaluate the line source blast wave relaxation radius, the differential acoustic efficiency, etc., to compute an approximate total power balance during entry. Next, we analyzed the detailed signals arriving from Genesis using a numerical, signal detection and wave processing software package (Matseis/Infra_Tool). We established the initial and subsequent arrivals and evaluated its plane wave back azimuths and elevation arrival angles and the degree of maximum, pair-wise cross-correlation, its power spectrum, spectrogram analysis, standard seismic f-k analysis, etc. From the associated entry parameters, we computed the kinetic energy density conservation properties for the propagating line source blast waves and compared these predictions against observed ground-based infrasound amplitude and wave period data as a function of range. We discovered that previously computed differential acoustic efficiencies were unreliable at Mach numbers below about 10. This is because we had assumed that a line source explosion was applicable, whereas at very low Mach numbers, typical of recovered meteorites, the detailed source characteristics are closer to those of supersonic objects. When corrections for these unphysical, very high efficiencies were made, agreement between theory and observations improved. We also made an assessment for the energy of the blast wave source from the ground-based infrasound data using several other techniques that were also adapted from previous bolide studies. Finally, we made a top-down-bottom-up assessment of the line source wave normals propagating via refraction downward into the complex middle atmospheric environment. This assessment proved to be generally consistent with the digital signal processing analysis and with the observed time delay between the known Genesis reentry and the infrasonic observations.

As in the observations, the leading mode of simulated variability exhibits a dipole pattern with positive anomalies in the Pacific sector associated with negative anomalies in the Atlantic. It is found that in the Pacific ocean circulation changes associated with variable wind forcing modify the ocean heat flux convergence and sea ice transport, resulting in sea surface temperature and sea ice anomalies. The Pacific ice and ocean anomalies persist over a number of years due to reductions in ocean shortwave absorption reinforcing the initial anomalies. In the Atlantic sector, no single process dominates in forcing the anomalies. Instead there are contributions from changing ocean and sea ice circulation and surface heat fluxes. While the absorbed solar radiation in the Atlantic is modified by the changing surface albedo, the anomalies are much shorter-lived than in the Pacific because the ocean circulation transports them northward, removing them from ice formation regions. Sea ice and ocean anomalies associated with the El Nino-Southern Oscillation and the Southern Annular Mode both exhibit a dipole pattern and contribute to the leading mode of ice and ocean variability.

One of the major challenges of systems biology today is to devise generally applicable methods of interpreting this data in a way that will shed light on the complex relationships between multiple genes and their products. The importance of such information is clear, not only as an aid to areas of research like drug design, but also as a contribution to our understanding of the mechanisms behind an organism's ability to react to its environment. RESULTS: We detail one computational approach for using gene expression data to identify response networks in an organism. The method is based on the construction of biological networks given different sets of interaction information and the reduction of the said networks to important response sub-networks via the integration of the gene expression data. As an application, the expression data of known stress responders and DNA repair genes in Mycobacterium tuberculosis is used to construct a generic stress response sub-network. This is compared to similar networks constructed from data obtained from subjecting M.tuberculosis to various drugs; we are thus able to distinguish between generic stress response and specific drug response. We anticipate that this approach will be able to accelerate target identification and drug development for tuberculosis in the future.

The success of this technique is greatly augmented by the availability of publicly accessible proteomic databases for specific pathogenic bacteria. To aid proteomic detection analyses for the causative agent of anthrax, we have constructed a comprehensive proteomic catalogue of vegetative Bacillus anthracis Sterne cells using liquid chromatography tandem-mass spectrometry. Proteins were separated by molecular weight or isoelectric point prior to tryptic digestion. Alternatively, the whole protein extract was digested and tryptic peptides were separated by cation exchange chromatography prior to Reverse Phase-LC-MS/MS. The use of three complementary, pre-analytical separation techniques resulted in the identification of 1048 unique proteins, including 694 cytosolic, 153 membrane (including 27 cell wall), and 30 secreted proteins, accounting for 19% of the total predicted proteome. Each identified protein was functionally categorized using the gene attribute database from TIGR CMR. These results provide a large proteomic catalogue of vegetative B. anthracis cells, and, coupled with the recent proteomic catalogue of B. anthracis spore proteins, form a thorough summary of proteins expressed in the active and dormant stages of this organism.

Thermodynamic analysis of the phase-equilibrium data revealed the existence of three energetically distinct types of H (sub 2) O, referred to as S-1, S-2, and S-3. At 23 degrees C and 26 mbar of H (sub 2) O-vapor pressure, chabazite has maximum H (sub 2) O occupancies of 8.2, 11.1, and 3.1 wt.% for S-1, S-2, and S-3, respectively. During dehydration, S-1 H (sub 2) O is lost first, followed by S-2 H (sub 2) O and then S-3 H (sub 2) O, with significant overlap for S-1 and S-2 as well as S-2 and S-3. The thermodynamics of chabazite-H (sub 2) O were modeled using three independent equilibrium formulations for S-1, S-2, and S-3. These formulations yielded standard-state molar Gibbs free energy of hydration of -21.8 + or - 0.6, -52.1 + or - 1.8, and -111.7 + or - 6.7 kJ/mol for S-1, S-2, and S-3. Standard-state molar enthalpies of hydration for each type of H (sub 2) O are -65.6 + or - 0.5, -100.1 + or - 1.6 and -156.9 + or - 6.2 kJ/mol, respectively. Integral molar values for the Gibbs free energy of hydration for each type of H (sub 2) O are -19.0 + or - 0.7, -40.1 + or - 2.1, and -76.9 + or - 9.6 kJ/mol, respectively. Integral molar values for the enthalpy of hydration for each type of H (sub 2) O are -62.8 + or - 0.6, -88.1 + or - 1.9, and -122.2 + or - 9.3 kJ/mol, respectively. Integration of the predicted total partial molar enthalpy of hydration for all three types of H (sub 2) O over the full H (sub 2) O content of chabazite gave an integral molar enthalpy of -39.65 + or - 9.3 kJ/mol relative to liquid water. The thermodynamic data obtained for the hydration of natural chabazite were used to predict the hydration state of chemically similar chabazites under various temperatures and P (sub H2O) , ranging from 25 to 400 degrees C and from 10 (super -5) to 10 (super 4) bars.

Sequence and terminal restriction fragment length polymorphism (T-RFLP) analysis of nifH and amoA PCR amplicons was performed on DNA samples from unburned, moderately burned, and severely burned soils of a mixed conifer forest. PCR results indicated that the soil biomass and proportion of nitrogen-fixing and ammonia-oxidizing species was less in soil from the fire-impacted sites than from the unburned sites. The number of dominant nifH sequence types was greater in fire-impacted soils, and nifH sequences that were most closely related to those from the spore-forming taxa Clostridium and Paenibacillus were more abundant in the burned soils. In T-RFLP patterns of the ammonia-oxidizing community, terminal restriction fragments (TRFs) representing amoA cluster 1, 2, or 4 Nitrosospira spp. were dominant (80 to 90%) in unburned soils, while TRFs representing amoA cluster 3A Nitrosospira spp. dominated (65 to 95%) in fire-impacted soils. The dominance of amoA cluster 3A Nitrosospira spp. sequence types was positively correlated with soil pH (5.6 to 7.5) and NH sub(3)-N levels (0.002 to 0.976 ppm), both of which were higher in burned soils. The decreased microbial biomass and shift in nitrogen-fixing and ammonia-oxidizing communities were still evident in fire-impacted soils collected 14 months after the fire.

Some SNPs confer selective advantages for microbial pathogens during infection and many others are powerful genetic markers for distinguishing closely related strains or isolates that could not be distinguished otherwise. To facilitate SNP discovery in microbial genomes, we have developed a web-based application, SNPsFinder, for genome-wide identification of SNPs. SNPsFinder takes multiple genome sequences as input to identify SNPs within homologous regions. It can also take contig sequences and sequence quality scores from ongoing sequencing projects for SNP prediction. SNPsFinder will use genome sequence annotation if available and map the predicted SNP regions to known genes or regions to assist further evaluation of the predicted SNPs for their functional significance. SNPsFinder can generate PCR primers for all predicted SNP regions according to user's input parameters to facilitate experimental validation.

Despite this many of its most fundamental and complex phenomena scale with size in a surprisingly simple fashion. For example, metabolic rate scales as the 3/4-power of mass over 27 orders of magnitude, from molecular and intracellular levels up to the largest organisms. Similarly, time-scales (such as lifespans and growth rates) and sizes (such as bacterial genome lengths, tree heights and mitochondrial densities) scale with exponents that are typically simple powers of 1/4. The universality and simplicity of these relationships suggest that fundamental universal principles underly much of the coarse-grained generic structure and organisation of living systems. We have proposed a set of principles based on the observation that almost all life is sustained by hierarchical branching networks, which we assume have invariant terminal units, are space-filling and are optimised by the process of natural selection. We show how these general constraints explain quarter power scaling and lead to a quantitative, predictive theory that captures many of the essential features of diverse biological systems. Examples considered include animal circulatory systems, plant vascular systems, growth, mitochondrial densities, and the concept of a universal molecular clock. Temperature considerations, dimensionality and the role of invariants are discussed. Criticisms and controversies associated with this approach are also addressed.

The early history of negative security assurances is traced from the 1960s, noting that lack of consensus exists on the issue as evidenced by the compromise language of the 2000 NPT Review Conference's final document & the inability of the 2005 Review Conference's Preparatory Committee reach any recommendations on them. The value of negative security assurances is questioned in light of the rise of weapons of mass destruction other than nuclear, eg, biological & chemical. These threats need to be reconsidered. It is argued that by reserving the right to respond to a WMD attack with any weapon in its arsenal, the Bush administration is not advocating a policy of nuclear preemption nor is it shifting significantly away from the extant policy on negative security assurances. Whether nuclear ambiguity is an effective deterrence strategy is then considered before contending that, in light of renewed proliferation, efforts must be made to address insecurity in potential proliferant states. In addition, The US might consider expanding its positive security assurances given today's security environment. It is likely that security assurances will see changes in their relative importance in the future & their reassessment is seen to be a key to making the most of opportunities. J.

In this report we describe the effect of a shock wave on the crystallographic orientation of quartz crystals in quartzite from the Vredefort impact site in South Africa. Preferred orientation of bulk quartzite samples was measured by time-of-flight neutron diffraction. With a random distribution of c-axes, a weak but distinct difference between the orientation distribution of positive and negative rhombs was observed, as illustrated with pole figures and inverse pole figures. Results for the natural Vredefort sample are compared with deformation experiments in which the reorientation occurs as a result of mechanical Dauphine twinning under stress. We conclude that stresses during the impact produced twinning and that the direction of the compressive shock wave can be inferred from the preferred orientation pattern. Specifically, positive rhombs become aligned perpendicular to the direction of compressive stress.

Experiments were conducted in a flexible cell hydrothermal apparatus to evaluate fluid-rock (aquifer plus aquitard) reactions that may adversely impact the integrity of the repository. A 5.5 molal NaCl brine-rock system was held at 200 degrees C and 200 bars (20 MPa) for 32 days (772 h) to approach steady state, then injected with CO (sub 2) and allowed to react for an additional 45 days (1079 h). In a separate experiment at 200 degrees C and 200 bars, the system was allowed to react for 77 days (1845 h) without injection of CO (sub 2) . Corroded magnesite and euhedral siderite crystallized in a paragenetic sequence after CO (sub 2) injection. Nucleation and growth of siderite on shale suggests the aquitard is a reactive component in the system. Changes in elemental abundances in the brine following addition of CO (sub 2) include pH decrease and depletion of sodium due to accelerated growth of analcime. A pH increase follows pressure and temperature decrease and loss of saturated CO (sub 2) from acidic brine. Silica concentrations and dissolution rates are enhanced and silica precipitation inhibited in the acidic brine. Geochemical reactions in a carbon repository extend beyond pH decrease and carbonate mineral precipitation. Rock-dominated reaction systems yield to acid-dominated and related reactions controlled by mixed fluid equilibria (i.e., a fluid-dominated system). Escape of CO (sub 2) or migration of brine from the repository into overlying aquifers may cause silica super-saturation and increased alkalinity due to mixed fluid phase equilibria. These geochemical changes could be monitored in aquifers as indicators of repository integrity. Return of silica super-saturated brine to a rock-dominated reaction system buffered to neutral pH conditions may enhance precipitation of quartz, chalcedony, or amorphous silica. In addition to the potential effects (beneficial or deleterious) that silica super-saturation and precipitation may hold for repository performance, an understanding of the effects of multi-phase equilibrium relationships between supercritical CO (sub 2) and dissolved silica in aquifer-brine systems also raises new questions for a variety of geologic systems. Multi-phase fluid equilibria may, for example, account for quartz cements in some sedimentary basin sandstones and quartz vein mineralization in some ore districts.

Factors include emplacement conditions, post-emplacement processes, and the nature and timing of interactions with water during cooling. The model uses the multiphase finite element heat and mass transfer (FEHM) code, which has been enhanced to handle conditions up to 1500 degrees C. The instantaneous emplacement of a 750 degrees C ignimbrite with internal gas pressures of up to 0.5 MPa (lithostatic) has a great effect on the variably saturated substrate. A water table present within a few tens of meters of the base of the ignimbrite produces a region of high pressure and temperature that exists for about 20 years, driving vapor upward through the ignimbrite as diffuse flow and in gas escape structures and enhancing cooling at the base of the ignimbrite. Variations in initial gas pressure between atmospheric and lithostatic conditions have little effect on the thermal evolution. The results of the numerical modeling of 20- and 40-m-thick ignimbrites indicate that, even for moderate pore water saturations in the substrate, vaporization and resultant pressurization may exceed lithostatic confining pressures in the upper substrate and basal ignimbrite, and explosive pressure release may occur, resulting in the development of discrete fumarole conduits or phreatic explosions. The likelihood for explosive pressure release appears to be greater when the nominal ignimbrite thickness is on the order of the depth of a buried valley. The pressure buildup is enhanced by the geometry of the ignimbrite-substrate interface, especially at convex corners such as on the edges of a buried valley. The boiling zones at the top and bottom of a cooling ignimbrite involve the development of a heat-pipe, which provides an efficient means of transporting heat from the superheated tephra out tens of meters into the ambient environment. The predicted temporal evolution of temperature, pressure, and vapor flow in a 40-m ignimbrite support the conceptual model of degassing, welding and compaction, devitrification, and alteration occurring concomitantly in the first several years after emplacement and driven in part by production and migration of meteoric steam. This vapor flowing through the ignimbrite matrix at 5X10 (super -5) kg s (super -1) in the first 10 years enhances devitrification in any part of the ignimbrite above the base in nonwelded deposits. In the case where welding occurs, lower permeability limits the diffuse flow of gas upward through the ignimbrite from the region of boiling and pore pressurization at the base, and enhanced devitrification in the basal parts of the ignimbrite may occur where pore vapors circulate in abundance. Immediately above the welded zone, a devitrified horizon may develop where the upper boiling/condensation zone and perched meteoric infiltration results in enhanced saturations.

Convection beneath the lid is time-dependent and characterized by passive upwellings and cold sheet-like downwellings. The heat flux scaling relationship agrees with results from experiment, two-dimensional numerical simulations, and boundary layer stability analysis. Without a mobile lithosphere, low heat transport efficiency and extensive melting during evolution of the terrestrial planets, which are predicted by two-dimensional studies, also apply in fully three-dimensional spherical shell geometry. The scaling relationships for convection induced stresses in the lid are also very similar to those obtained in two dimensions. This supports the idea that initiation of subduction in the stagnant lid convection regime requires a very weak lithosphere.

We found that mutual obligation between agents was maximized for indiscriminant sharing, the same condition that has been observed in several traditional cultures. Alternate sharing strategies, including ones based on kinship or sharing with those who share in return, reduced mutual obligation. When theft & sanctions were introduced into the simulations, we found that mutual obligation was maximized when individual norms were strong, ie, when there was little tolerance to theft. Collective sanctions, represented by the ostracism of non-normative agents, produced levels of mutual obligation comparable to the case of strong individual norms, but with significant risk of population collapse. The probability of long term survival was highest when tolerance to transgressions was either very low or very high & we propose that this may be one reason for the similarity of normative systems across diverse egalitarian cultures. 3 Tables, 4 Figures, 18 References.

In order to make such models more realistic, we have used variable thermal conductivities (k) that depend on pressure, temperature, and mineralogy (olivine, wadsleyite, or ringwoodite), as determined recently by Xu et al. [Xu, Y., Shankland, T.J., Linhardt, S., Rubie, D.C., Langenhorst, F., Klasinski, K., 2004. Thermal diffusivity and conductivity of olivine, wadsleyite and ringwoodite to 20 GPa and 1373 K. Phys. Earth Planet. Inter. 143-144, 321-336]. We have used these variable conductivities to model a variety of slabs with thermal parameters (vertical subduction ratexage of lithosphere at the trench) ranging between 3500 and 17,000 km. Our models show that when radiative transfer is included, k could plausibly be increased by as much as 2W/(mK) relative to a standard constant lithospheric value (3.138W/(mK); [Stein, C.A., Stein, S., (1992) A model for the global variation in oceanic depth and heat flow with lithospheric age. Nature 359, 123-129.], causing temperatures in the interiors of the slabs to increase by 50-100 degrees C. In turn, the volume of metastable olivine in the slabs is reduced by as much as 20-30%, with the maximum depth of olivine metastability decreasing by 30-50 km. In general, the maximum depths of olivine metastability are 160-230 km less than the depths of the deepest seismicity. Even in the extreme case of Tonga, metastable olivine falls short of the deepest earthquakes by 140 km in our model. Even taking the various uncertainties into account, these results indicate that deep-focus earthquakes occur in regions already transformed to wadsleyite or ringwoodite and must therefore be caused by a mechanism other than transformational faulting.

An important rate-limiting step in the resonance assignment process is accurate identification of resonance peaks in the NMR spectra. Peak-picking schemes range from incomplete (which lose essential assignment connectivities) to noisy (which obscure true connectivities with many false ones). We introduce an automated preassignment process that removes false peaks from noisy peak lists by requiring consensus between multiple NMR experiments and exploiting a priori information about NMR spectra. This process is designed to accept multiple input formats and generate multiple output formats, in an effort to be compatible with a variety of user preferences. RESULTS: Automated preprocessing with APART rapidly identifies and removes false peaks from initial peak lists, reduces the burden of manual data entry, and documents and standardizes the peak filtering process. Successful preprocessing is demonstrated by the increased number of correct assignments obtained when data are submitted to an automated assignment program.

The mix of reverse-fault and strike-slip mechanisms in this region, with northwest-southeast to north-south maximum horizontal stress, S (sub Hmax) , implies that the effective slab pull is no more than approximately 10% of the total negative buoyancy operating on the subducting slab. Numerical models of the intraplate stress field predict a slab-pull component along the Sumatra and Java boundary segments of 2.82+ or -0.82 and 0.89+ or -0.35X10 (super 12) N.m (super -1) , respectively. Mantle tomographic constraints coupled with insights from analogue modeling suggest that the differences relate to variations in the depth extent of the slabs and the degree of slab support provided by the transition zone. These results help resolve apparent contradictions between insights from intraplate stress fields and plate dynamics; i.e., although plate motion is dominated by subduction, slab pull is only poorly expressed in the intraplate stress field because of low slab-plate coupling.

The Konso area is known for its abundant vertebrate fossils, including those of Homo erectus and Australopithecus boisei, and its rich Acheulean archaeological assemblages. The fluvial, floodplain, lake margin, and lacustrine sediments of the formation were mostly deposited between 1.9 and 1.4 Ma, based on single-crystal (super 40) Ar/ (super 39) Ar ages of interbedded marker tuffs. The formation is subdivided into the Sorobo, Turoha, Kayle, and Karat Members, in ascending stratigraphic order. Each member contains dark brown or dark grey clay beds of lake margin and/or lacustrine origin, suggesting the recurrence of lake environments. Most of the fossils and artifacts derive from whitish grey or brown silt, sand, and gravel beds widely exposed between the finer sediments. These beds appear to have been deposited in an emerging marginal floodplain following repeated recession of the palaeo-lake. The depositional history of the Konso Formation reveals aspects of Quaternary rifting at the southern terminus of the Main Ethiopian Rift. Rifting, subsidence, and sedimentation in the Ganjuli graben occurred in the Konso area mainly between 1.9 and 1.4 Ma, while active faulting with associated volcanism during the Pleistocene was mostly confined to the middle part of the graben between Lakes Abaya and Chamo and to the Segen basin east of Konso. A shift of rift-related faulting and subsidence from the Konso area eastward to the Segen basin is likely to have resulted in the erosion and exposure of the fossiliferous Konso Formation.

This terrane is loosely termed the Dahlonega Gold Belt because of the occurrence of economically important minerals found throughout, and may be associated with the Ashland-Wedowee belt that continues southwest into Alabama. The importance of this terrane is that it occurs structurally adjacent to the eastern margin of the Laurentian portion of the Appalachian metamorphic core, making it the most inboard accreted terrane in this region of the southern Appalachians. Total thickness of the PCF and associated units is unknown due to lack of facing criteria, complex folding, and terrane bounding faults on either side. Recent reports of zircon (IMP) U-Pb ages (felsic meta-volcanics) suggest an Ordovician age of crystallization (460-480 Ma). New geochemical data shows evidence for petrogenesis of the PCF as volcanic arc basalts and rhyolites, possibly in a back-arc setting. Nd isotopic evolution values show that these rocks likely have little or no contribution from Mesoproterozoic crust as the age corrected ( approximately 460 Ma) epsilon Nd values of the felsic meta-volcanics are -3.3 to 4.7 and the mafics have values of 3.3 to approximately 7, which shows generation from a depleted mantle source. Sm/Nd isotope systematics shows evidence of a mixing line for the felsic meta-volcanics that may define a range between basalt and average shale composition. 87/86 Sr is heterogeneous among the felsic samples and is either a result of some disturbance or is primary in that these rocks were sampled from different parent magmas. A poorly constrained Rb/Sr isochron (or 'scatter-chron') yields an 'age' of 386 + or - 140 Ma. This may represent a metamorphic disturbance age, but the age of crystallization falls well within the error. Most Appalachian arc-terranes show evidence of interaction with older, Mesoproterozoic (Grenville) crust, while the PCF appears to have formed as an island arc related to B-type subduction, and shows (Nd isotopic) similarities to the northern Appalachian Exploits Arc that developed in the middle of the Iapetus Ocean.

A new image is created of the crust-mantle boundary from teleseismic body wave data for a 950 km-long transect across the Rio Grande Rift. Numerical modelling compares predicted thermal and tectonic evolution of the extending lithosphere (by 28% over 280 km), to the seismic imaging results. The lithospheric strain ranges from pure shear (ductile deformation of the lower crust and mantle lithosphere) to single shear with strain localization in detachments in the lithosphere. The topography of the Rio Grande rift and region of Cainozoic extension (NW to SE) is illustrated, with the modelled topography of the base of the crust. A lithospheric-scale cross-section shows the predicted surface topography and uplift of the Moho. Vertical mantle upwelling is reduced through the extension in the lower crust, and may explain the lack of rift-related volcanism compared to other global rift systems.

Parental magmas are of two types: K-depleted silica-undersaturated, derived from the partial melting of lithospheric mantle with residual amphibole, and tholeiitic, derived from either asthenospheric or lithospheric mantle. Variability in silica-undersaturated basalts reflects contributions of melts derived from lherzolitic and pyroxenitic mantle, representing heterogeneous lithosphere associated with the suture. The K depletion is inherited by fractionated, crustally contaminated derivatives (hawaiites and mugearites), leading to distinctive incompatible trace element signatures, with Th/(Nb,Ta) and La/(Nb,Ta) greater than, but K/(Nb,Ta) similar to, Bulk Silicate Earth. These compositions dominate the mafic and intermediate lavas, and the JMVF is therefore derived largely, and perhaps entirely, from melting of fertile continental Jemez lineament lithosphere during rift-related extension. Significant variations in Pb and Nd isotope ratios ( (super 206) Pb/ (super 204) Pb = 17.20-18.93; (super 143) Nd/ (super 144) Nd = 0.51244-0.51272) result from crustal contamination, whereas 87Sr/86Sr is low and relatively uniform (0.7040-0.7048). We compare the effects of contamination by low- (super 87) Sr/ (super 86) Sr crust with assimilation of high- (super 87) Sr/ (super 86) Sr granitoid by partial melting, with Sr retained in a feldspathic residue. Both models satisfactorily reproduce the isotopic features of the rocks, but the lack of a measurable Eu anomaly in most JMVF mafic lavas is difficult to reconcile with a major role for residual plagioclase during petrogenesis.

Single genome fingerprinting (SGF) provides not only the size but also the order of the restriction fragments, which adds another dimension to the information that can be used for discrimination. Analysis of single organisms may eliminate the need to culture cells and thereby significantly reduce analysis time. In addition, samples containing mixtures of several organisms can be analyzed. For analysis, cells are embedded in an agarose matrix, lysed, and processed to yield intact DNA. The DNA is then deposited on a derivatized glass substrate. The elongated genome is digested with a restriction enzyme and stained with the intercalating dye YOYO- 1. DNA is then quantitatively imaged with a fluorescence microscope and the fragments are sized to an accuracy [greater-or-equal, slanted]90% by their fluorescence intensity and contour length. Single genome fingerprints were obtained from pure samples of adenovirus, from bacteriophages lambda and T4 GT7, and from a mixture of the three viral genomes. SGF will enable the fingerprinting of uncultured and unamplified samples and allow rapid identification of microorganisms with applications in forensics, medicine, public health, and environmental microbiology.

Thus, we refined and characterized a potassium hydrogen phthalate (KHP) buffered solution with pH 4.55, termed phagolysosomal simulant fluid (PSF), for use in a static dissolution technique. To characterize the simulant, beryllium dissolution in PSF was compared to dissolution in the J774A.1 murine cell line. The effects of ionic composition, buffer strength, and the presence of the antifungal agent alkylbenzyldimethylammonium chloride (ABDC) on beryllium dissolution in PSF were evaluated. Beryllium dissolution in PSF was not different from dissolution in the J774A.1 murine cell line (p = 0.78) or from dissolution in another simulant having the same pH but different ionic composition (p = 0.73). A buffer concentration of 0.01-M KHP did not appear adequate to maintain pH under all conditions. There was no difference between dissolution in PSF with 0.01-M KHP and 0.02-M KHP (p = 0.12). At 0.04-M KHP, beryllium dissolution was increased relative to 0.02-M KHP (p = 0.02). Use of a 0.02-M KHP buffer concentration in the standard formulation for PSF provided stability in pH without alteration of the dissolution rate. The presence of ABDC did not influence beryllium dissolution in PSF (p = 0.35). PSF appears to be a useful and appropriate model of In vitro beryllium dissolution when using a static dissolution technique. In addition, the critical approach used to evaluate and adjust the composition of PSF may serve as a framework for characterizing PSF to study dissolution of other metal and oxide particles.

The virus is highly variable and evolves rapidly, making it an elusive target for the immune system and for vaccine and drug design. At present, some 30 000 HCV sequences have been published. A central website that provides annotated sequences and analysis tools will be helpful to HCV scientists worldwide. RESULTS: The HCV sequence database collects and annotates sequence data and provides them to the public via a website that contains a user-friendly search interface and a large number of sequence analysis tools, based on the model of the highly regarded Los Alamos HIV database. The HCV sequence database was officially launched in September 2003. Since then, its usage has steadily increased and is now at an average of [approx]280 visits per day from distinct IP addresses.

The gold surface was charged and the influence of the charge at the solid support on the structure and integrity of the phospholipid bilayer was investigated using the specular reflection of neutrons and electrochemical measurements. When the surface charge density is close to zero, the lipid vesicles fuse directly on the surface to form a bilayer with a small number of defects and hence low water content. When the support's surface is negatively charged the film swells and incorporates water due to the field driven poration of the membrane. When the charge density is more negative then-8 mu C cm super(-2) the bilayer is detached from the metal surface. However, it remains in close proximity to the metal electrode, suspended on a thin cushion of water. The film thicknesses, calculated from neutron reflectivity, have allowed us to determine the tilt angle of the lipid molecules as a function of the support's charge density. The lipid molecules are tilted 55 from the surface normal at zero charge density but become significantly more perpendicular (30 tilt angle) at charge densities more negative than-8 mu C cm super(-2). The tilt angle measurements are in very good agreement with previous IR studies. This paper describes the highlights of a more in-depth study which is fully described in [1], .

Structural parameters such as the density and thickness of the lipid layer, extension of the GM sub(1) oligosaccharide headgroup, and orientation and position of the protein upon binding are reported. Both CTAB sub(5) and CTB sub(5) were measured to have [not, vert, similar]50% coverage when bound to the lipid monolayer. X-ray GID experiments show that both the lipid monolayer and the cholera toxin layer are crystalline. The effects of X- ray beam damage have been assessed and the monolayer/toxin structure does not change with time after protein binding has saturated.

To decrease the genetic distances between candidate immunogens and field virus strains, we have designed and synthesized an artificial group M consensus env gene (CON6 gene) to be equidistant from contemporary HIV-1 subtypes and recombinants. This novel envelope gene expresses a glycoprotein that binds soluble CD4, utilizes CCR5 but not CXCR4 as a coreceptor, and mediates HIV-1 entry. Key linear, conformational, and glycan- dependent monoclonal antibody epitopes are preserved in CON6, and the glycoprotein is recognized equally well by sera from individuals infected with different HIV-1 subtypes. When used as a DNA vaccine followed by a recombinant vaccinia virus boost in BALB/c mice, CON6 env gp120 and gp140CF elicited gamma interferon-producing T-cell responses that recognized epitopes within overlapping peptide pools from three HIV-1 Env proteins, CON6, MN (subtype B), and Chn19 (subtype C). Sera from guinea pigs immunized with recombinant CON6 Env gp120 and gp140CF glycoproteins weakly neutralized selected HIV-1 primary isolates. Thus, the computer-generated "consensus" env genes are capable of expressing envelope glycoproteins that retain the structural, functional, and immunogenic properties of wild-type HIV-1 envelopes.

AN - 85390306; pmid-15704405 AB - Results are reported of the first systematic study of anomalous nonlinear fast dynamics and slow dynamics in a number of solids. Observations are presented from seven diverse materials showing that anomalous nonlinear fast dynamics (ANFD) and slow dynamics (SD) occur together, significantly expanding the nonlinear mesoscopic elasticity class. The materials include samples of gray iron, alumina ceramic, quartzite, cracked Pyrex, marble, sintered metal, and perovskite ceramic. In addition, it is shown that materials which exhibit ANFD have very similar ratios of amplitude-dependent internal-friction to the resonance-frequency shift with strain amplitude. The ratios range between 0.28 and 0.63, except for cracked Pyrex glass, which exhibits a ratio of 1.1, and the ratio appears to be a material characteristic. The ratio of internal friction to resonance frequency shift as a function of time during SD is time independent, ranging from 0.23 to 0.43 for the materials studied.

The low and mid-altitude cusps have been extensively studied previously with a number of low-altitude satellites, but only little is known about the distant part of the magnetospheric cusps. During the spring-time, the trajectory of the Cluster fleet is well placed for dayside, high-altitude magnetosphere investigations due to its highly eccentric polar orbit. Wide coverage of the region has resulted and, depending on the magnetic dipole tilt and the solar wind conditions, the spacecraft are susceptible to encounter: the plasma mantle, the high-altitude cusp, the dayside magnetosphere (i.e. dayside plasma sheet) and the distant exterior cusp diamagnetic cavity. The spacecraft either exit into the magnetosheath through the dayside magnetopause or through the exterior cusp-magnetosheath interface. This paper is based on Cluster observations made during three high-altitude passes. These were chosen because they occurred during different solar wind conditions and different inter-spacecraft separations. In addition, the dynamic nature of the cusp allowed all the aforementioned regions to be sampled with different order, duration and characteristics. The analysis deals with observations of: (1) both spatial and temporal structures at high-altitudes in the cusp and plasma mantle, (2) signatures of possible steady reconnection, flux transfer events (FTE) and plasma transfer events (PTE), (3) intermittent cold (<100eV) plasma acceleration associated with both plasma penetration and boundary motions, (4) energetic ions (5-40keV) in the exterior cusp diamagnetic cavity and (5) the global structure of the exterior cusp and its direct interface with the magnetosheath.

AN - 70170322; 16604682 AB - Adjoint functions have been used with forward functions to compute gradients in implicit (iterative) solution methods for inverse problems in optical tomography, geoscience, thermal science and other fields, but only once has this approach been used for inverse solutions to the Boltzmann transport equation. In this paper, this approach is used to develop an inverse method that requires only angle-independent flux measurements, rather than angle-dependent measurements as was done previously. The method is applied to a simplified form of the transport equation that does not include scattering. The resulting procedure uses measured values of gamma-ray fluxes of discrete, characteristic energies to determine interface locations in a multilayer shield. The method was implemented with a Newton-Raphson optimisation algorithm and it worked very well in numerical 1-D spherical test cases. A more sophisticated optimisation method would better exploit the potential of the inverse method.

AN - 70159368; 16604650 AB - With the introduction of continuous-energy heavy charged particle transport in MCNP5, the need for tracking charged particles in a magnetic field becomes increasingly important. Two methods for including magnetic field effects on charged particles are included in the proton transport version of the code. The first technique utilises transfer maps produced by the beam dynamics simulation and analysis code COSY INFINITY. This method is fast and accurate; however, its use is limited to void cells only and to ensembles of particles with a fairly small energy spread. The second technique, particle ray tracing, is based on an algorithm adopted from the MARS transport code. This method can be applied to both void and material cells and is valid over a very large range of particle energies. Results from tracking particles in a quadrupole 'identity lens' using the two techniques are compared.

AN - 70158628; 16604688 AB - In order to reduce the user's time and the computer time needed to solve deep penetration problems, an automated variance reduction capability has been developed for the MCNP Monte Carlo transport code. This new variance reduction capability developed for MCNP5 employs the PARTISN multigroup discrete ordinates code to generate mesh-based weight windows. The technique of using deterministic methods to generate importance maps has been widely used to increase the efficiency of deep penetration Monte Carlo calculations. The application of this method in MCNP uses the existing mesh-based weight window feature to translate the MCNP geometry into geometry suitable for PARTISN. The adjoint flux, which is calculated with PARTISN, is used to generate mesh-based weight windows for MCNP. Additionally, the MCNP source energy spectrum can be biased based on the adjoint energy spectrum at the source location. This method can also use angle-dependent weight windows.

AN - 70151217; 16604608 AB - The developmental version of MCNP5 has recently been extended to provide for continuous-energy transport of high-energy protons. This enhancement involves the incorporation of several significant new physics models into the code. Multiple Coulomb scattering is treated with an advanced model that takes account of projectile and nuclear target form factors. In the next version, this model will provide a coupled sampling of both angular deflection and collisional energy loss, including straggling. The proton elastic scattering model is also new, based on recent theoretical work. Charged particle transport in the presence of magnetic fields is accomplished either by using transfer maps from the COSY INFINITY code (in void regions) or by using an algorithm adapted from the MARS code (in void regions or in scattering materials). Work is underway to validate and implement the latest versions of the Cascade-Exciton Model and the Los Alamos Quark-Gluon String Model, which will process inelastic nuclear interactions and generate secondary particles.

AN - 69046395; 16381684 AB - A new Monte Carlo method is being developed to calculate eigenfunction fluxes in critical or near-critical nuclear systems. The correct estimation of fluxes is essential for radiation protection and shielding near these systems, in addition to isotope production, isotope depletion, nuclear criticality and other applications. The proposed method applies to Monte Carlo criticality eigenvalue calculations in which the fission sites in one generation are used as fission sources in subsequent generations. The usual Monte Carlo power iteration method for such problems often calculates fluxes (eigenfunctions) that are inaccurate and very different in symmetric parts of a problem geometry. The proposed method calculates flux distributions by estimating an approximate fission matrix. The way the fission matrix is estimated and used differs from other recent works. Preliminary results are promising.

AN - 69045635; 16381695 AB - SOURCES is a computer code that determines neutron production rates and spectra from (alpha,n) reactions, spontaneous fission and delayed neutron emission owing to the decay of radionuclides in homogeneous media, interface problems and three-region interface problems. The code is also capable of calculating the neutron production rates due to (alpha,n) reactions induced by a monoenergetic beam of alpha particles incident on a slab of target material. The (alpha,n) spectra are calculated using an assumed isotropic angular distribution in the centre-of-mass system with a library of 107 nuclide decay alpha-particle spectra, 24 sets of measured and/or evaluated (alpha,n) cross sections and product nuclide level branching fractions, and functional alpha particle stopping cross sections for Z < 106. Spontaneous fission sources and spectra are calculated with evaluated half-life, spontaneous fission branching and Watt spectrum parameters for 44 actinides. The delayed neutron spectra are taken from an evaluated library of 105 precursors. The code outputs the magnitude and spectra of the resultant neutron sources. It also provides an analysis of the contributions to that source by each nuclide in the problem.

AN - 67721147; 15769803 AB - Radiation sources producing short pulses of photon radiation are widespread. Such sources include electron linear accelerators and field emission impulse generators. It is often desirable to measure leakage and skyshine radiation for these sources in real time and at environmental levels as low as 0.02 microSv per pulse. This note provides an overview of the design and performance of a commercial, real-time, pulsed photon dosemeter (PPD) capable of single-pulse dose measurements over the range from 0.02 to 20 microSv. The PPD may also be operated in a multiple-pulse mode that integrates the dose from a train of pulses over a 3 s period. A pulse repetition rate of up to 300 Hz is accommodated.

AN - 67360891; 15643939 AB - Bacteria may be beneficial for alleviating actinide contaminant migration through processes such as bioaccumulation or metal reduction. However, sites with radioactive contamination often contain multiple additional contaminants, including metals and organic chelators. Bacteria-based bioremediation requires that the microorganism functions in the presence of the target contaminant, as well as other contaminants. Here, we evaluate the toxicity of actinides, metals and chelators to two different bacteria proposed for use in radionuclide bioremediation, Deinococcus radiodurans and Pseudomonas putida, and the toxicity of Pu(VI) to Shewanella putrefaciens. Growth of D. radiodurans was inhibited at metal concentrations ranging from 1.8 microM Cd(II) to 32 mM Fe(III). Growth of P. putida was inhibited at metal concentrations ranging from 50 microM Ni(II) to 240 mM Fe(III). Actinides inhibited growth at mM concentrations: chelated Pu(IV), U(VI) and Np(V) inhibit D. radiodurans growth at 5.2, 2.5 and 2.1 mM respectively. Chelated U(VI) inhibits P. putida growth at 1.7 mM, while 3.6 mM chelated Pu(IV) inhibits growth only slightly. Pu(VI) inhibits S. putrefaciens growth at 6 mM. These results indicate that actinide toxicity is primarily chemical (not radiological), and that radiation resistance does not ensure radionuclide tolerance. This study also shows that Pu is less toxic than U and that actinides are less toxic than other types of metals, which suggests that actinide toxicity will not impede bioremediation using naturally occurring bacteria.

AN - 67339935; 15459942 AB - Staphylococcal enterotoxins SEB and SEC3 and toxic shock syndrome toxin TSST-1 act as superantigens by overstimulating the human immune system and thereby compromise host defense. The mechanism of pathogenesis is explained on the basis of superantigen binding to the MHC class II receptor on the antigen presenting cell and to the T cell receptor (TcR) on the T cell. SEB, SEC3 and TSST-1 bind as intact proteins and make contacts with the alpha1 subdomain (DRalpha) of MHC class II and Vbeta subdomain of TcR. SEB, SEC3 and TSST-1 show specificities for different TcRVbeta isoforms. We have designed three different chimeras linking the same DRalpha with different TcRVbeta isoforms to specifically target SEB, SEC3 and TSST-1 and inhibit their pathogenesis. Here, we show by molecular modeling that the DRalpha, TcRVbeta and linker of a given chimera interact with the target superantigen in a type-specific manner. An initial model of the complex is constructed on the basis of observed inter-molecular contacts between DRalpha/TcRVbeta and the superantigens. A constant temperature (300 K) 200 ps molecular dynamics is performed to sample different conformations of a chimera-superantigen complex by utilizing the flexibility of the (GSTAPPA)(2) linker while maintaining the native folds of superantigen, DRalpha and TcRVbeta and the observed intermolecular contacts. After equilibration, 100 molecular dynamic snapshots are minimized and analyzed. This provides descriptions of various pairwise interactions at the contact interface in the complex and important clues on single site mutations on the chimera that may enhance the stability of a given superantigen-chimera complex.

We solve them numerically including two possible types of fragmentation: into large pieces and into a cluster of small fragments. We have written a Fortran code that computes the motion, ablation and light intensity of a meteoroid at chosen heights, and allows for the ablation and shape density coefficients sigma and K, as well as the luminous efficiency tau , to be variable with height/time. We calibrated our fragmentation model (FM) by the best fit to observational values for the motion, ablation, radiation, fragmentation and the terminal masses (recovered meteorites) for the Lost City bolide. The FM can also handle multiple and overlapping meteor flares. We separately define both the apparent and intrinsic values of sigma , K, and tau . We present in this paper values of the intrinsic luminous efficiency as function of velocity, mass, and normalized air density. Detailed results from the successful application of the FM to the Lost City, Innisfree, and Benesov bolides are also presented. Results of applying the FM to 15 bolides with very precise observational data are presented in a survey mode (Table 7). Standard deviations of applying our FM to all these events correspond to the precision of the observed values. Typical values of the intrinsic ablation coefficient are low, mostly in the range from 0.004 to 0.008 s (super 2) km (super -2) , and do not depend on the bolide type. The apparent ablation coefficients reflect the process of fragmentation. The bolide types indicate severity of the fragmentation process. The large differences of the "dynamic" and "photometric" mass from numerous earlier studies are completely explained by our FM. The fragmentation processes cannot be modeled simply by large values of the apparent ablation coefficient and of the apparent luminous efficiency. Moreover, our new FM can also well explain the radiation and full dynamics of very fast meteoroids at heights from 200 km to 130 km.

We approached the task utilizing several combinations of two distinct methods: an unsupervised algorithm for expanding words associated with GO nodes, and an annotation methodology which treats annotation as categorization of terms from a protein's document neighborhood into the GO. Results The evaluation results indicate that the method for expanding words associated with GO nodes is quite powerful; we were able to successfully select appropriate evidence text for a given annotation in 38% of Task 2.1 queries by building on this method. The term categorization methodology achieved a precision of 16% for annotation within the correct extended family in Task 2.2, though we show through subsequent analysis that this can be improved with a different parameter setting. Our architecture proved not to be very successful on the evidence text component of the task, in the configuration used to generate the submitted results. Conclusion The initial results show promise for both of the methods we explored, and we are planning to integrate the methods more closely to achieve better results overall.

By integrating site-wide data into a numerical model of the aquifer beneath the plateau we provide new insight into large-scale aquifer properties and fluxes. This model is useful for understanding hydrologic mechanisms, assessing the magnitudes of different terms in the overall water budget, and, through sampling, for interpreting contaminant migration velocities in the overlying vadose zone. Modeling results suggest that the majority of water produced in well fields on the plateau, extracted at rates approaching 70% of total annual recharge, is derived from storage. This result is insensitive to assumptions about the percentage of total recharge that occurs in the near vicinity of water supply wells, because of strong anisotropy in the aquifer that prevents fast transport of local recharge to deeper units from which production occurs. Robust estimates of fluxes in the shallow portion of the aquifer immediately down gradient of LANL are important for contaminant transport simulations. Our model calculations show that these fluxes have decreased in the past 50 years by approximately 10% because of production in water supply wells. To explore the role of parameter uncertainty in flux prediction, a predictive analysis method was applied. Results showed that predicted flux through older basalts in the aquifer can vary by a factor of three because of uncertainty in aquifer properties and total recharge. We explored the impact of model parameter uncertainty on these results; however, the true uncertainty of our predictions, including the impact of possible conceptual model errors, is likely to be larger and is difficult to quantify.

Since 1943, LANL has operated on the Pajarito Plateau of north-central New Mexico, performing national security research and development, particularly involving nuclear weapons design and engineering. There is an ongoing environmental characterization and remediation program as a result of the legacy of these operations. The flow and transport processes in the thick vadose zone in this semiarid region have been examined extensively at this site, and significant scientific findings have advanced our understanding and predictive abilities. This special section highlights the noteworthy field and modeling investigations conducted at LANL. The authors believe that these articles will be of benefit to the community of hydrologists working on vadose zone flow and transport by providing complex observational data sets and accompanying modeling studies to interpret the field data.

In this study, conceptual models of vadose zone flow and transport processes are presented and then supported through the interpretation of field data, including synthesis with numerical models. The conceptual models differentiate the rate of percolation by their location and surface hydrologic setting, including wet and dry canyons, and wet, dry, and disturbed mesas. Net infiltration beneath wet canyons is the highest, with rates on the order of a meter per year (100-1000 mm yr super(-1)). Transport to the regional aquifer beneath the wettest canyons is likely on the order of several years to several decades, depending on the thicknesses of the various hydrostratigraphic layers. Perched water is sometimes found beneath wetter canyons and is associated with near-surface alluvial systems and at intermediate depths along low-permeability interfaces such as buried soils or unfractured regions of basalt flows. Percolation through the volcanic tuffs is generally considered to be via matrix-dominated flow, whereas fracture flow may play a key role in contaminant transport through densely welded tuffs or basalt units beneath wet canyons. Infiltration beneath dry canyons and dry mesas is much slower (10 mm yr super(-1) or less), yielding transport times to the aquifer of hundreds to several thousands of years. However, long-term surface disturbances at mesa-top locations may alter infiltration rates such that at a local scale, the infiltration rates temporarily approach those of wetter canyons.

Family members share a catalytic core region of about 30 kDa, where inhibitors operate competitively by acting as substrate mimics. This protein family typifies many that are challenging for bioinformatic analysis because of relatively modest sequence conservation and small size. Results: Phylogenetic relationships of TyrA domains were evaluated in the context of combinatorial patterns of specificity for the two substrates, as well as the presence or absence of a variety of fusions. An interactive tool is provided for prediction of substrate specificity. Interactive alignments for a suite of catalytic-core TyrA domains of differing specificity are also provided to facilitate phylogenetic analysis. tyrA membership in apparent operons (or supraoperons) was examined, and patterns of conserved synteny in relationship to organismal positions on the 16S rRNA tree were ascertained for members of the domain Bacteria. A number of aromatic- pathway genes (hisHb, aroF, aroQ) have fused with tyrA, and it must be more than coincidental that the free-standing counterparts of all of the latter fused genes exhibit a distinct trace of syntenic association. Conclusions: We propose that the ancestral TyrA dehydrogenase had broad specificity for both the cyclohexadienyl and pyridine nucleotide substrates. Indeed, TyrA proteins of this type persist today, but it is also common to find instances of narrowed substrate specificities, as well as of acquisition via gene fusion of additional catalytic domains or regulatory domains. In some clades a qualitative change associated with either narrowed substrate specificity or gene fusion has produced an evolutionary "jump" in the vertical genealogy of TyrA homologs. The evolutionary history of gene organizations that include tyrA can be deduced in genome assemblages of sufficiently close relatives, the most fruitful opportunities currently being in the Proteobacteria. The evolution of TyrA proteins within the broader context of how their regulation evolved and to what extent TyrA co-evolved with other genes as common members of aromatic-pathway regulons is now feasible as an emerging topic of ongoing inquiry.

Because of the need for very high specific activity products, methods other than direct neutron capture reactions (n,� -elastic and n,n'-inelastic routes) are required to insure that the highest specific activity - and hopefully no carrier added (nca) - radioisotopes are available. Two major methods to obtain nca radioisotopes from reactors are through the use of radionuclide generator systems using reactor-produced parents and the formation of desired radioisotopes through beta-decay of reactor-produced species. In this paper we describe our recent development of new approaches to obtain nca 177Lu from the decay of reactor-produced 177Yb and free of the long-lived 177mLu (T1/2 = 160 d) radiocontaminant. We also describe preliminary results of our new “ indirect' method for the production of 195mPt via decay of 195mIr, reactor-produced by neutron irradiation of highly enriched 193Ir.

Bayesian inference applied to the electromagnetic inverse problem. Human Brain Mapping 7, 195; Schmidt, D.M., George, J.S., Ranken, D.M., Wood, C.C., 2001. Spatial-temporal bayesian inference for MEG/EEG. In: Nenonen, J., Ilmoniemi, R. J., Katila, T. (Eds.), Biomag 2000: 12th International Conference on Biomagnetism. Espoo, Norway, p. 671]. Schmidt et al. (1999) focused on the analysis of data at a single point in time employing an extended region source model. They subsequently extended their work to a spatiotemporal Bayesian inference analysis of the full spatiotemporal MEG/EEG data set. Here, we formulate spatiotemporal Bayesian inference analysis using a multi-dipole model of neural activity. This approach is faster than the extended region model, does not require use of the subject's anatomical information, does not require prior determination of the number of dipoles, and yields quantitative probabilistic inferences. In addition, we have incorporated the ability to handle much more complex and realistic estimates of the background noise, which may be represented as a sum of Kronecker products of temporal and spatial noise covariance components. This reduces the effects of undermodeling noise. In order to reduce the rigidity of the multi-dipole formulation which commonly causes problems due to multiple local minima, we treat the given covariance of the background as uncertain and marginalize over it in the analysis. Markov Chain Monte Carlo (MCMC) was used to sample the many possible likely solutions. The spatiotemporal Bayesian dipole analysis is demonstrated using simulated and empirical whole-head MEG data.

Hydroxyethyl methacrylate (HEMA)-based hydrogels have been developed for the controlled release of CPC. Initial burst release of the biocide can be controlled and sustained release can be achieved for more than two weeks. The burst and sustained release can be adjusted by varying the amount of anionic monomer (AMPSA), crosslink content (DEGDMA), release media, hydrogel surface area, and CPC loading. After removing the CPC-loaded hydrogel from solution and drying, the release of CPC can also be reactivated. Very interesting swelling behavior was observed for CPC-loaded hydrogels due to the electrostatic and hydrophobic interactions between the polymer hydrogel and CPC. In addition, HEMA-based hydrogels can be used to recover or absorb CPC from aqueous solutions. By increasing the amount of AMPSA in the HEMA-based hydrogel, more CPC can be absorbed from solution. The absorption is also enhanced by agitating the solution.

A combination of T7 promoter-based vectors with hexa-His affinity tags and BL21 E. coli strains with additional tRNA genes to supplement sparsely used E. coli codons have been most successful. The expressed proteins have a wide range of molecular weights and number of transmembrane helices. Expression of these proteins has been observed in the membrane and insoluble fraction of E. coli cell lysates and, in some cases, in the soluble fraction. The highest expression levels in the membrane fraction were restricted to a narrow range of molecular weights and relatively few transmembrane helices. In contrast, overexpression in insoluble aggregates was distributed over a broad range of molecular weights and number of transmembrane helices.

Split protein tags can perturb protein solubility or may not work in living cells. Green fluorescent protein (GFP) fusions can misfold or exhibit altered processing. Fluorogenic biarsenical FLaSH or ReASH substrates overcome many of these limitations but require a polycysteine tag motif, a reducing environment and cell transfection or permeabilization. An ideal protein tag would be genetically encoded, would work both in vivo and in vitro, would provide a sensitive analytical signal and would not require external chemical reagents or substrates. One way to accomplish this might be with a split GFP, but the GFP fragments reported thus far are large and fold poorly, require chemical ligation or fused interacting partners to force their association, or require coexpression or co-refolding to produce detectable folded and fluorescent GFP. We have engineered soluble, self-associating fragments of GFP that can be used to tag and detect either soluble or insoluble proteins in living cells or cell lysates. The split GFP system is simple and does not change fusion protein solubility.

The recent completion of the genome sequence of the causative agent, Neisseria gonorrhoeae, opens up an entirely new set of approaches for studying this organism and the diseases it causes. Here, we describe the initial phases of the construction of an expression-capable clone set representing the protein-coding ORFs of the gonococcal genome using a recombination-based cloning system. The clone set thus far includes 1672 of the 2250 predicted ORFs of the N. gonorrhoeae genome, of which 1393 (83%) are sequence-validated. Included in this set are 48 of the 61 ORFs of the gonococcal genetic island of strain MS11, not present in the sequenced genome of strain FA1090. L-arabinose-inducible glutathione-S-transferase (GST)-fusions were constructed from random clones and each was shown to express a fusion protein of the predicted size following induction, demonstrating the use of the recombination cloning system. PCR amplicons of each ORF used in the cloning reactions were spotted onto glass slides to produce DNA microarrays representing 2035 genes of the gonococcal genome. Pilot experiments indicate that these arrays are suitable for the analysis of global gene expression in gonococci. This archived set of Gateway super( registered )uentry clones will facilitate high-throughput genomic and proteomic studies of gonococcal genes using a variety of expression and analysis systems. In addition, the DNA arrays produced will allow us to generate gene expression profiles of gonococci grown in a wide variety of conditions. Together, the resources produced in this work will facilitate experiments to dissect the molecular mechanisms of gonococcal pathogenesis on a global scale, and ultimately lead to the determination of the functions of unknown genes in the genome.

The point infiltration estimates are based on a combination of techniques that include the use of the Richards equation, the chloride mass-balance method, and numerical modeling. The infiltration rates estimated with these techniques were extrapolated to uncharacterized parts of the study area using maps of environmental variables that are correlated with infiltration (such as topography, vegetation cover, and surficial geology and structure) and spatial algorithms implemented with GIS software that use the mapped variables. The map indicates that infiltration rates on mesas of the Pajarito Plateau are generally 25 mm yr super(-1) in mixed conifer areas and >200 mm yr super(-1) in areas vegetated by aspen. An irregular transition zone with infiltration rates between 2 to 25 mm yr super(-1) exists near the western edge of the Pajarito Plateau adjacent to the Sierra de los Valles. This transition zone extends to lower elevations on the north-facing slopes of deeply incised canyons. Canyon-bottom infiltration rates are highly variable, ranging from several hundred millimeters per year in canyons with large watersheds that have their headwaters in the Sierra de los Valles or in canyons that receive effluent from Laboratory operations, to several millimeters per year in canyons that have their headwaters on the Pajarito Plateau but do not receive Laboratory effluent. The total net infiltration of approximately 10.6 x 10 super(6) m super(3) yr super(-1) (8600 acre-ft yr super(-1)) is consistent with estimates of the steady-state groundwater discharge to perennial streams in the study area, whereas the relative rates of infiltration within the study area are consistent with the distribution of natural and anthropogenic tracers such as tritium in perched and regional groundwaters. Limitations of the study are that it does not address the effects of the Cerro Grande fire on the hydrology of the study area, nor does it completely capture the complex and sometimes incompletely documented history of Laboratory generated discharges during its 60-yr history.

The agreement of the numerical models and the data was quite acceptable, both qualitatively and quantitatively. The migration of water injected in an open interval of the wellbore exhibited flow that was controlled by gravity and, to a lesser extent, capillary forces. A sensitivity analysis showed that the behavior is well captured with laboratory determined hydrologic parameters and less so if rocks with higher capillary suction are simulated. More complex model formulations that explicitly account for fractures were also tested, but it was found that these models reproduce the field behavior only when parameters are selected that minimize the role of fractures. Therefore, the SCM is favored due to its simpler formulation and ease with which it is implemented in large-scale flow and transport simulations. Discrete fracture simulations are used to illustrate that fractures are predicted to play a minor role in most subunits of the Bandelier tuff: high matrix permeability allows water entering fractures to quickly imbibe into the matrix, thereby reducing the tendency of these rocks to exhibit preferential fracture flow. In contrast, water flow through Basalts present on the Pajarito Plateau is predicted to be dominated by fractures.

Deep perched groundwater occurs at widely dispersed locations across the Pajarito Plateau. A total of 33 perched-zone occurrences were identified in 29 wells. The saturated thickness of perched zones is highly variable, ranging from about 1 to >122 m (>400 ft). Observations are consistent with a conceptual model of low- permeability horizons on which infiltrating water sits. Deep perched groundwater is most often found beneath wet canyons, suggesting that in addition to perching horizons, locally high percolation rates are required to yield saturated conditions. Two conceptual models of perching systems are considered, one relatively stagnant and one more dynamic. To simulate deep perched groundwater in vadose zone flow models, a new method is developed that considers the interfaces between hydrogeologic units to be the horizons where the saturated permeability is lower than either of the units above or below the interface. A constant multiplier called the permeability reduction factor is applied at the interface between two hydrostratigraphic units to simulate the perching horizon. We demonstrate the method with two-dimensional numerical simulations performed for Los Alamos Canyon, replicating perched saturation as observed and showing how contaminant dispersal may be enhanced in certain perched systems compared with dispersion in the underlying zone of regional saturation.

By perturbation expansions, we first derive partial differential equations governing the zeroth-order head h super((0)) and the first-order head term h super((1)), where orders are in terms of the standard deviation of the log transmissivity. We then solve h super((0)) and h super((1)) analytically, both of which are expressed as infinite series. The head perturbation h super((1)) is then used to derive expressions for autocovariance of the hydraulic head and the cross covariance between the log transmissivity and head. The expressions for the mean flux and flux covariance tensor are formulated from the head moments based on Darcy's law. Using numerical examples, we demonstrate the convergence of these solutions. We also examine the accuracy of these first-order solutions by comparing them with solutions from both Monte Carlo simulations and the numerical moment equation method.

The solutions assume that (i) the constitutive relations for the hydraulic conductivity and water content as function of the pressure head are exponential, (ii) the initial water content distribution is a steady-state distribution, and (iii) the root water uptake is a function of depth. Three simple forms of root water uptake are considered, that is, uniform, stepwise, and exponential functional forms. The lower boundary of the rooted soil profile studied is a water table, while at the upper boundary time-dependent surface fluxes are specified, either infiltration or evaporation. Application of the Kirchhoff transformation allows us to linearize Richards' equation and derive exact solutions. The steady-state solution is given in a closed form and the transient solution has the form of an infinite series. The solutions are used to simulate the hydraulic behavior of the rooted soils under different conditions of root uptake and surface flux. The restricted assumptions for the solutions may limit the applicability, but the solutions are relatively flexible and easy to implement compared to other analytical and numerical schemes. The analytical solutions provide a reliable and convenient means for evaluating the accuracy of various numerical schemes, which usually require sophisticated algorithms to overcome convergence and mass balance problems.

From 1999 to 2002, we assessed retrospectively the epidemiological, clinical, and treatment characteristics of pulmonary tuberculosis in the hospitals of the Mexican Institute of Public Health in the state of Colima (Mexico). We included 184 cases diagnosed with pulmonary tuberculosis. A database containing demographic, epidemiological, and clinical information was constructed and analyzed. We estimate a median patient delay of 83 d and a mean treatment delay of 2.3 d. Of 14 cases suspected for multiresistance and microbiologically assayed, 5 were found to carry a multi-drug-resistant strain. We also found a significant association between a short patient delay and the presence of hemoptysis (p = 0.002) or dyspnea (p < 0.001). 86 patients (46.8%) were sputum smear microscopy negative at the end of treatment and 40 (21.7%) completed treatment giving an overall success rate of 68.5%, which compares unfavorably with the World Health Organization target success rate of 85%.

The complex hydrostratigraphy of the canyon is captured using geologic characterization of extensive deep-well drilling samples, along with surface mapping. A water budget study for the surface and shallow subsurface hydrology is used to estimate spatially varying infiltration rates along the canyon. Three-dimensional flow model results show that mesa-top infiltration rates on the order of 1 mm yr super(-1), and canyon-bottom rates several orders of magnitude higher, capture the water content profiles from available wells within the model domain. However, a range of a factor of three higher and lower than these mean values is also consistent with the data. Transient flow simulations show that episodic infiltration events can be effectively averaged in steady-state flow modeling, but transients that last on the order of a decade or more, such as climate related or anthropogenically induced transients, significantly change the predicted water content. Modeling of tritium transport through the vadose zone indicates that even for a nonsorbing contaminant, most, but not all, of the contaminant released since in the past 40 yr should still be present in the vadose zone. The mass predicted to reach the water table is primarily in locations in the canyon where the Bandelier Tuff is not present. Available groundwater surveillance data for regional aquifer water are consistent with this result.

However, this topic has received little attention in the peer-reviewed literature. The value of this approach is that activities are conducted below the waste, providing clear and rapid verification of containment. Here we report on two studies that examined the utility of horizontal boreholes for environmental characterization and monitoring under radioactive waste disposal pits. Both studies used core sample analyses to determine the presence of various radionuclides, organic compounds, or metals. At one borehole site, water content and pore-water chloride concentrations were also used to interpret vadose zone behavior. At another site, we examined the feasibility of using flexible membrane liners in uncased boreholes for periodic monitoring. For this demonstration, these retrievable liners were air-injected into boreholes on multiple occasions carrying different instrument packages for environmental surveillance. These included a neutron logging device to measure volumetric water at regular intervals, high-absorbency collectors that wicked available water from borehole walls, or vent tubes that were used to measure air permeability and collect air samples. The flexible and retrievable liner system was an effective way to monitor water content and measure in situ air permeability. The high-absorbency collectors were efficient at extracting liquid water for contaminant analyses even at volumetric water contents below 10%, and revealed tritium migration below one disposal pit. Both demonstration studies proved that effective characterization and periodic monitoring in horizontal boreholes is both feasible and adaptable to many waste disposal problems and locations.

We evaluated water balances, vegetation cover, rooting patterns, and soil profiles of two landfill-cover designs (two plots each) more than a decade after installation at semiarid Los Alamos National Laboratory, NM, USA: a conventional design of 20 cm of topsoil over compacted crushed-tuff and an integrated design of 71 cm of topsoil over an engineered barrier designed to induce lateral flow (geotextile overlying 46 cm of gravel). Water balances for both designs had ~3% of precipitation as seepage; the integrated plots lost <1% of water as interflow, probably because the barrier interface had only a 5% slope. The conventional design had a net loss of stored soil water and proportionally more evapotranspiration than the integrated design. After more than a decade, (i) vegetation changes included increased biomass and species diversity on most plots, with proportionally fewer invading species and more extensive rooting in the integrated plots; (ii) the geotextile was largely unchanged; and (iii) infiltration and subsequent water penetration occurred primarily via macropores, including root channels and animal burrows. Both cover designs effectively minimized seepage during their initial decade, but observed effects of environmental processes such as succession and burrowing are expected to become progressively more important determinants of cover performance over additional decades.

Modeling of Tracer Test Results AN - 16197823; 6495507 AB - Field observations of bromide transport in the unsaturated zone are used to constrain simulations that provide estimates of bulk porosity and permeability for the Cerros del Rio. The Cerros del Rio basalt is of particular interest because it underlies many of the potential waste sites at the Los Alamos National Laboratory. A highly simplified model is able to capture the general behavior of the breakthrough data. The simplifying assumption is that the basalt can be modeled as a homogeneous continuum with high permeability and low porosity. We estimate that the permeability of the bulk rock is 10 super(-11) to 10 super(-12) m super(2), whereas the porosity is estimated to lie between 0.001 and 0.01. The porosity estimates from this study are particularly useful for kilometer-scale simulations that include flow and transport through the Cerros del Rio basalt because estimates based on other methods, such as core testing, are highly scale dependent and should not be extrapolated to larger scales. Although this model does not include the complex physics of flow in the fractured basalt, it is useful for simulations on the kilometer scale that require averaging of rock properties and optimization of computational speed. The porosity and permeability values obtained from this analysis will help to weight probability distributions used in the kilometer-scale simulations of contaminant transport.

We focus on 1,1,1-trichloroethane (TCA) vapor transport from a liquid-waste disposal site. The conceptual model incorporates several physical processes, including partitioning of TCA into the liquid phase, saturation- dependent diffusion, diffusion through asphalt, and interaction with the atmosphere. Three-dimensional numerical simulations that use the conceptual model of TCA transport are then calibrated to pore-gas monitoring data. Adjustable parameters in the numerical simulations are limited to (i) the vapor- phase diffusion coefficients for the different geologic units, asphalt cover, and land-atmosphere boundary layer and (ii) the fixed concentrations in the two shaft clusters. By including all of the components of the conceptual model in our numerical simulations we were able to achieve a reasonable match between the simulated plume and site data for two alternate conceptual models of asphalt, one with asphalt as a diffusive barrier and one without asphalt as a diffusive barrier. A goodness-of-fit analysis shows that the best-fit simulations are highly correlated to 132 data points from 21 boreholes. The simulations demonstrate that diffusive behavior describes the general characteristics of the current subsurface vapor plume. Effective vapor-phase diffusion coefficients used in the simulations that best fit the data suggest that barometric pumping is not contributing to diffusion in the deep vadose zone; however, it is likely that barometric pumping is occurring in fractures near the mesa edge. We conclude that asphalt is most likely acting as a barrier to diffusion at this site. The numerical simulations validate that the conceptual model developed for this study is a useful tool for analyzing TCA transport within the mesas of the Pajarito Plateau.

Each single-square-root term in the double-square-root equation is approximated by a split-step Fourier operator coupled with an optimized finite-difference operator. The optimization of the finite-difference coefficients is achieved by maximizing the maximum dip angle of the entire model, leading to better ability for the new method to handle steeply dipping events in a medium with strong lateral velocity variations. Numerical results with the impulse response show that the proposed method is more accurate than other approaches including the split-step Fourier and the pseudo-screen migration methods. Results with the SEG/EAGE salt model show that the proposed method resolves the salt boundary and the sub-salt weak reflectors more accurately than the split-step Fourier migration method.

The one-way wave-equation-based propagator is used to extrapolate the wavefields from both the source and receivers to a target region. The plane wave analysis method is used to decompose the wavefields and calculate the wavenumber domain resolution function. The method can be applied to complex models without smoothing velocity. It can also handle irregular acquisition geometry and finite frequency band. The resulting resolution function can be used to estimate image quality or correct the image distortion caused by the uneven illumination.

The method operates on common-shot data in the frequency domain and uses a combination of the split-step Fourier propagator implemented in the wavenumber and space domains and a second order finite-difference propagator applied in the space domain. The coefficients in the finite-difference propagator are optimized for the entire extrapolation depth interval. It can accurately and efficiently handle large lateral velocity variations and steep interfaces. We conduct impulse response studies, and using the method to migrate a common-shot dataset for the SEG/EAGE 3D salt model and a common-shot deepwater Gulf of Mexico dataset from Unocal. The results demonstrate that the method has great potential to accurately image complex 3D subsalt structures.

Traditional resolution analysis is based on calculation of a Point Spreading Function (PSF) in the wavenumber domain from the scattering wavenumbers at the image point. This spectral representation can be converted into a space-domain PSF by Fourier Transform. However, other issues influence image resolution or distort migrated images. For example, the velocity model is generally not reliably known and variations of the model from the true structure can have a significant impact on image focus, thus reducing resolution. Another factor that limits resolution is the type and accuracy of the propagator used in imaging. To compare the resolution of images obtained when using ray-based Kirchhoff migration with that obtained from wave equation migration, we developed a 2D heterogeneous model that can be numerically simulated. Poststack migrations of exploding reflector data obtained for the model show that the PSF are influenced by the migration operator and are not necessarily the same as expected from the range of scattering wavenumbers estimated using a simple analysis approach.

Magnetic, electromagnetic (EM), ground penetrating radar (GPR) and seismic methods have been employed. Important results have been obtained at four different sites. Two examples of interpretive results are presented in this abstract. The application of geophysics to archaeology has both scientific and regulatory consequences. Widespread use of geophysics could potentially improve the site evaluation process. From an educational perspective, the data and problems associated with these archaeological sites have been challenging, stimulating and compatible with the goals of the SAGE course.

The goal is to verify approximate detection capabilities of InSAR, assess differences in the results, and test how the two results can be reconciled. First, we calculated the expected surface deformation from all earthquakes greater than magnitude 4 in areas with available InSAR data (347 events). A search for deformation from the events in the interfer-ograms yielded four possible events with magnitudes less than 6. The search for deformation was based on a visual inspection as well as cross-correlation in two dimensions between the measured signal and the expected signal. A grid-search algorithm was then used to estimate focal mechanism and depth from the InSAR data. The results were compared with locations and focal mechanisms from published catalogs. An independent relocation using seismic data was also performed. The seismic locations fell within the area of the expected rupture zone for the three events that show clear surface deformation. Therefore, the technique shows the capability to resolve locations with high accuracy and is applicable worldwide. The depths determined by InSAR agree with well-constrained seismic locations determined in a 3D velocity model. Depth control for well-imaged shallow events using InSAR data is good, and better than the seismic constraints in some cases. A major difficulty for InSAR analysis is the poor temporal coverage of InSAR data, which may make it impossible to distinguish deformation due to different earthquakes at the same location.

Spectral structure from U(VI) luminescence at the "-" vicinal regions and featureless, weak luminescence at the "+" vicinal regions are consistent with previously reported observations of enrichment at the former sites during calcite growth. Luminescence spectra differ between the non-equivalent regions of the crystal, with the spectral features from the "-" vicinal region corresponding to those observed in bulk calcite samples. Subtle spectral shifts are observed from U(VI) co-precipitated with microcrystalline calcite synthesized by a different method, and all of the U(VI)-calcite sample spectra differ significantly from that of U(VI) co-precipitated with aragonite.The step-selective incorporation of U(VI) can be explained by a proposed model in which the allowed orientation for adsorption of the dominant calcium uranyl triscarbonate species is controlled by the atomic arrangement at step edges. Differences in the tilt angles of carbonate groups between non-equivalent growth steps favor adsorption of the calcium uranyl triscarbonate species at "-" steps, as observed in experiments.

Within the first 24 hr following the DFE mainshock, we located more than 250 earthquakes, which occurred throughout the entire Yellowstone National Park region. The elevated seismicity rate continued for about 30 days and followed a modified Omori law decay with a P value of 1.02+ or -0.07. For a declustered earthquake catalog, the seismicity following the 2002 DFE uniquely stands out with a significance of 30sigma . The increase in seismicity occurred over all magnitude bands. In general, we observed that seismicity following the DFE outlined the spatial pattern of past seismicity routinely observed in the Yellowstone National Park region. However, we found significant differences in triggered seismicity inside and outside the caldera. Earthquakes inside the Yellowstone caldera occurred preferentially as clusters close to major hydrothermal systems, were of larger magnitude, and seismicity decayed more rapidly. This suggests that either different trigger mechanisms were operating inside and outside the caldera or that the crust responded differently to the same trigger mechanism depending on its different mechanical state. Compared with other sites that experienced remote earthquake triggering following the 2002 DFE, Yellowstone showed the most vigorous earthquake activity. We attribute this to strong directivity effects of the DFE, which caused relatively large peak dynamic stresses (0.16-0.22 MPa) in Yellowstone, and to the volcanic nature of Yellowstone.

With the 1957 M (sub w) 8.3 Gobi-Altay, Mongolia, earthquake as the only other well-documented case of significant, nearly simultaneous rupture of both thrust and strike-slip faults, this feature of the 2002 Denali fault earthquake provides a unique opportunity to investigate the mechanisms responsible for development of these large, complex events. We find that the geometry of the faults and the orientation of the regional stress field caused slip on the Susitna Glacier fault to load the Denali fault. Several different stress orientations with oblique right-lateral motion on the Susitna Glacier fault replicate the triggering of rupture on the Denali fault about 10 sec after the rupture nucleates on the Susitna Glacier fault. However, generating slip directions compatible with measured surface offsets and kinematic source inversions requires perturbing the stress orientation from that determined with focal mechanisms of regional events. Adjusting the vertical component of the principal stress tensor for the regional stress field so that it is more consistent with a mixture of strike-slip and reverse faulting significantly improves the fit of the slip-rake angles to the data. Rotating the maximum horizontal compressive stress direction westward appears to improve the fit even further.

Both events were predominantly strike-slip and ruptured structures associated with the Denali fault system. Previous studies have shown that the mainshock began with failure on a relatively small northeast-striking reverse fault, before breaking out for 300 km of right-lateral strike-slip rupture. Aftershock patterns suggest that the foreshock ruptured a region west of the mainshock, which began near the eastern extent of the foreshock sequence and proceeded east-southeast. To constrain and to quantify source duration and directivity effects, we examine surface-wave displacement seismograms and use an empirical Green's function (EGF) to isolate and explore mainshock rupture kinematics. Our particular interest lies in large-amplitude focussing caused by directivity. We observe Love and Rayleigh wave amplification of two orders of magnitude in the period range from 10 to 33 sec. These remarkable directivity-enhanced surface waves triggered small earthquakes more than 3000 km from the mainshock rupture.

Three episodes of rupture can be identified from broadband ( approximately 0.1-5.0 Hz) waveforms. The Denali fault earthquake started as a M (sub w) 7.3 thrust event. Subsequent right-lateral strike-slip rupture events with centroid depths of 9 km occurred about 22 and 49 sec later. The teleseismic P waves are dominated by energy at intermediate frequencies (0.1-1 Hz) radiated by the thrust event, while the SH waves are dominated by energy at lower frequencies (0.05-0.2 Hz) radiated by the strike-slip events. The strike-slip events exhibit strong directivity in the teleseismic SH waves. Correcting the recorded P-wave acceleration spectra for the effect of the free surface yields an estimate of 2.8X10 (super 15) N m for the energy radiated by the thrust event. Correcting the recorded SH-wave acceleration spectra similarly yields an estimate of 3.3X10 (super 16) N m for the energy radiated by the two strike-slip events. The average rupture velocity for the strike-slip rupture process is 1.1beta -1.2beta . The strike-slip events were located 90 and 188 km east of the epicenter. The rupture length over which significant or resolvable energy is radiated is, thus, far shorter than the 340-km fault length over which surface displacements were observed. However, the seismic moment released by these three events, 4X10 (super 20) N m, was approximately half the seismic moment determined from very low-frequency analyses of the earthquake. The difference in seismic moment can be reasonably attributed to slip on fault segments that did not radiate significant or coherent seismic energy. These results suggest that very large and great strike-slip earthquakes can generate stress pulses that rapidly produce substantial slip with negligible stress drop and little discernible radiated energy on fault segments distant from the initial point of nucleation. The existence of this energy-deficient rupture mode has important implications for the evaluation of the seismic hazard of very large strike-slip earthquakes.

I have also determined focal mechanisms from first-motion analysis and waveform modeling for many of the M> or =5.5 events. Limited phase and waveform information for the 1912 M (sub s) 7.2 earthquake are consistent with rupture at shallow depth on a right-lateral strike-slip fault, although the limited data cannot distinguish between a range of possible mechanisms. Most other M> or =4.5 earthquakes occurring within the region prior to 1989 represent thrust/reverse faulting or strike-slip faulting adjacent to the Denali fault system. These results highlight the role thrust faulting plays in the deformation of the Denali region. Stress analysis shows continuity in the direction of maximum compressive stress (sigma (sub 1) ) between the western Denali fault zone and the Castle Mountain fault/Upper Cook Inlet region, suggesting the crust is behaving rigidly to transfer compression to the Denali fault zone and faults located to the north.

Rupture of the Susitna Glacier fault generated scarps on ice of the Susitna and West Fork glaciers and on tundra and surficial deposits along the southern front of the central Alaska Range. Based on detailed mapping, 27 topographic profiles, and field observations, we document the characteristics and slip distribution of the 2002 ruptures and describe evidence of pre-2002 ruptures on the fault. The 2002 surface faulting produced structures that range from simple folds on a single trace to complex thrust-fault ruptures and pressure ridges on multiple, sinuous strands. The deformation zone is locally more than 1 km wide. We measured a maximum vertical displacement of 5.4 m on the south-directed main thrust. North-directed backthrusts have more than 4 m of surface offset. We measured a well-constrained near-surface fault dip of about 19 degrees at one site, which is considerably less than seismologically determined values of 35 degrees -48 degrees . Surface-rupture data yield an estimated magnitude of M (sub w) 7.3 for the fault, which is similar to the seismological value of M (sub w) 7.2. Comparison of field and seismological data suggest that the Susitna Glacier fault is part of a large positive flower structure associated with northwest-directed transpressive deformation on the Denali fault. Prehistoric scarps are evidence of previous rupture of the Sustina Glacier fault, but additional work is needed to determine if past failures of the Susitna Glacier fault have consistently induced rupture of the Denali fault.

Fitting the initial portion of the displacement waveforms indicates that the earthquake started with an oblique thrust subevent (subevent #1) with an east-west-striking, north-dipping nodal plane consistent with the observed surface rupture on the Susitna Glacier fault. Inversion of the remainder of the waveforms (0.02-0.5 Hz) for moment release along the Denali and Totschunda faults shows that rupture proceeded eastward on the Denali fault, with two strike-slip subevents (numbers 2 and 3) centered about 90 and 210 km east of the hypocenter. Subevent 2 was located across from the station at PS10 (Trans-Alaska Pipeline Pump Station #10) and was very localized in space and time. Subevent 3 extended from 160 to 230 km east of the hypocenter and had the largest moment of the subevents. Based on the timing between subevent 2 and the east end of subevent 3, an average rupture velocity of 3.5 km/sec, close to the shear wave velocity at the average rupture depth, was found. However, the portion of the rupture 130-220 km east of the epicenter appears to have an effective rupture velocity of about 5.0 km/sec, which is supershear. These two subevents correspond approximately to areas of large surface offsets observed after the earthquake. Using waveforms of the M 6.7 Nenana Mountain earthquake as empirical Green's functions, the high-frequency (110 Hz) envelopes of the M 7.9 earthquake were inverted to determine the location of high-frequency energy release along the faults. The initial thrust subevent produced the largest high-frequency energy release per unit fault length. The high-frequency envelopes and acceleration spectra (>0.5 Hz) of the M 7.9 earthquake can be simulated by chaining together rupture zones of the M 6.7 earthquake over distances from 30 to 180 km east of the hypocenter. However, the inversion indicates that there was relatively little high-frequency energy generated along the 60-km portion of the Totschunda fault on the east end of the rupture.

The Alaska Volcano Observatory operates short-period seismic networks on 24 historically active volcanoes in Alaska, 247-2159 km distant from the mainshock epicenter. We searched for evidence of triggered seismicity by examining the unfiltered waveforms for all stations in each volcano network for approximately 1 hr after the M (sub w) 7.9 arrival time at each network and for significant increases in located earthquakes in the hours after the mainshock. We found compelling evidence for triggering only at the Katmai volcanic cluster (KVC, 720-755 km southwest of the epicenter), where small earthquakes with distinct P and S arrivals appeared within the mainshock coda at one station and a small increase in located earthquakes occurred for several hours after the mainshock. Peak dynamic stresses of approximately 0.1 MPa at Augustine Volcano (560 km southwest of the epicenter) are significantly lower than those recorded in Yellowstone and Utah (>3000 km southeast of the epicenter), suggesting that strong directivity effects were at least partly responsible for the lack of triggering at Alaskan volcanoes. We describe other incidents of earthquake-induced triggering in the KVC, and outline a qualitative magnitude/distance-dependent triggering threshold. We argue that triggering results from the perturbation of magmatic-hydrothermal systems in the KVC and suggest that the comparative lack of triggering at other Alaskan volcanoes could be a result of differences in the nature of magmatic-hydrothermal systems.

Damage was principally the result of fault offset of tree roots and tilting of trees. Some trees were split by surface faults that intersected the base of their trunks or large taproots. A few trees appear to have been damaged by strong shaking. Many of the older trees damaged in 2002 were deformed and scarred. Some of these scarred trees exhibit past damage indicative of surface faulting and have abrupt changes in their annual ring patterns that coincide with the past damage. Annual ring counts from several of these older scarred trees indicate the damage was caused by surface rupture on the Denali fault in 1912. The only earthquake of sufficient magnitude that fits the requirements for timing and general location as recorded by the damaged trees is a widely felt M (sub s) 7.2-7.4 earthquake on 6 July 1912 informally referred to as the 1912 Delta River earthquake. Seismologic data and intensity distribution for the 1912 Delta River earthquake indicate that its epicenter was within 60-90 km of the Delta River and that rupture probably propagated toward the west. Inferred fault length, displacement, and rupture direction suggest the 1912 rupture was probably largely coincident with the western, lower slip section of the 2002 rupture.

Seismicity for 30 years prior to the 2002 earthquake sequence along the Denali fault was very light, with an average of four events with magnitude M (sub L) > or =3 per year. We observe a significant increase in the seismicity rate prior to the M (sub w) 7.9 event of 3 November 2002 within its epicentral region, starting about 8 months before its occurrence. The majority of the aftershocks of the M (sub w) 7.9 event are located within the upper 11 km of the crust and form several persistent clusters with a few aseismic patches along the ruptured fault. The most active aftershock source is associated with the epicentral region of the earthquake. The overall b-value of the aftershock sequence is 0.96 with the highest b-values within the epicentral region. We estimate that it will take 14 years for the seismicity rate to drop back to the background level. The stress regime across the region varies in space and time. The inferred stress regime prior to the 2002 sequence is predominately strike slip. Along the central part of the rupture zone, the orientations of the least- and intermediate-stress axes are reversed after the 2002 earthquake sequence. The maximum compressive stresses along the Denali fault rotate clockwise by up to 35 degrees ; the greatest rotations occur in the area of the rupture step-over from the Denali to the Totschunda fault. The inferred stress regime after the 2002 sequence reflects an interchanging thrusting and strike-slip faulting along the ruptured fault. The thrust faulting is concentrated in the epicentral region of the M (sub w) 7.9 event and along the rupture segments showing the largest surface offsets.

Wrangell and Mt. Veniaminof Volcanoes, Alaska, following the 3 November 2002 M (sub w) 7.9 Denali Fault earthquake AN - 51710876; 2005-041004 AB - The M (sub w) 7.9 Denali fault earthquake ruptured segments of the Susitna Glacier, Denali and Totschunda faults in central Alaska, providing a unique opportunity to look for intermediate-term (weeks to months) responses of active volcanoes to shaking from a large earthquake. The Alaska Volcano Observatory (AVO) monitors 24 volcanoes with seismograph networks. We examined one station per volcano. Digitally-filtered data for the period four weeks before to four weeks after the mainshock were plotted at a standard scale. Mt. Wrangell, the closest volcano to the epicenter (247 km), had a background rate of 16 events/day. For the following 30 days, however, its seismicity rate dropped by 50%. Mt. Veniaminof (1400 km from the epicenter) had a rate of 8 seismic events/day, but suffered a drop in seismicity by 80% after the maishock; this may have lasted for 15 days. The seismicity at both volcanoes is dominated by long-period seismic events. With the exception of Martin and Novarupta volcanoes, the other 20 volcanoes showed no changes in seismicity attributable to the Denali fault earthquake. We conclude that the changes in seismicity observed are real, and are related to the Denali fault earthquake. These seismicity drops are in strong contrast to cases of short-term triggered seismicity increases observed at other volcanic systems such as Martin-Novarupta, Mt. Rainier, Yellowstone, Mammoth Mountain, and The Geysers, Coso and Cerro Prieto (Mexico) geothermal fields. This suggests that fundamentally different mechanisms may be acting to modify seismicity at volcanoes.

We describe the spatial and temporal development of triggered activity in California and the Pacific Northwest, focusing on Mount Rainier, the Geysers geothermal field, the Long Valley caldera, and the Coso geothermal field. The onset of triggered seismicity at each of these areas began during the Love and Raleigh waves of the M (sub w) 7.9 wave train, which had dominant periods of 15 to 40 sec, indicating that earthquakes were triggered locally by dynamic stress changes due to low-frequency surface wave arrivals. Swarms during the wave train continued for approximately 4 min (Mount Rainier) to approximately 40 min (the Geysers) after the surface wave arrivals and were characterized by spasmodic bursts of small (M< or =2.5) earthquakes. Dynamic stresses within the surface wave train at the time of the first triggered earthquakes ranged from 0.01 MPa (Coso) to 0.09 MPa (Mount Rainier). In addition to the swarms that began during the surface wave arrivals, Long Valley caldera and Mount Rainier experienced unusually large seismic swarms hours to days after the Denali fault earthquake. These swarms seem to represent a delayed response to the Denali fault earthquake. The occurrence of spatially and temporally distinct swarms of triggered seismicity at the same site suggests that earthquakes may be triggered by more than one physical process.

The data demonstrate that National Earthquake Hazards Reduction Program (NEHRP) site classes are a useful way of grouping stations according to site amplification. In general, the sites underlain by lower shear-wave velocities have higher amplification. The amplification on NEHRP class D sites exceeds a factor of 2 relative to an average of motions on class C sites. The amplifications are period dependent. They are in rough agreement with those from previous studies, but the new data show that the amplifications extend to at least 10 sec, periods longer than considered in previous studies. At periods longer than about 14 sec, all sites have motion of similar amplitude, and the ground displacements are similar in shape, polarization, and amplitude for all stations. The displacement ground motion is dominated by a series of four pulses, which are associated with the three subevents identified in inversion studies (the first pulse is composed of P waves from the first subevent). Most of the high-frequency ground motion is associated with the S waves from subevent 1. The pulses from subevents 1 and 2, with moment releases corresponding to M 7.1 and 7.0, are similar to the pulse of displacement radiated by the M 7.1 Hector Mine earthquake. The signature from the largest subevent (M 7.6) is more subdued than those from the first two subevents. The two largest pulses produce response spectra with peaks at a period of about 15 sec. The spectral shape at long periods is in good agreement with the recent 2003 NEHRP code spectra but is in poor agreement with the shape obtained from Eurocode 8.

The rupture proceeded from west to east and began with a 48-km-long break on the previously unknown Susitna Glacier thrust fault. Slip on this thrust averaged about 4 m (Crone et al., 2004). Next came the principal surface break, along 226 km of the Denali fault, with average right-lateral offsets of 4.5-5.1 m and a maximum offset of 8.8 m near its eastern end. The Denali fault trace is commonly left stepping and north side up. About 99 km of the fault ruptured through glacier ice, where the trace orientation was commonly influenced by local ice fabric. Finally, slip transferred southeastward onto the Totschunda fault and continued for another 66 km where dextral offsets average 1.6-1.8 m. The transition from the Denali fault to the Totschunda fault occurs over a complex 25-km-long transfer zone of right-slip and normal fault traces. Three methods of calculating average surface slip all yield a moment magnitude of M (sub w) 7.8, in very good agreement with the seismologically determined magnitude of M 7.9. A comparison of strong-motion inversions for moment release with our slip distribution shows they have a similar pattern. The locations of the two largest pulses of moment release correlate with the locations of increasing steps in the average values of observed slip. This suggests that slip-distribution data can be used to infer moment release along other active fault traces.

We examined this increase in the context of the regional background seismicity using a catalog of 2651 earthquakes from 1 January 2000 to 30 June 2003. Statistical analyses of this catalog above spatially varying magnitudes of completeness ranging from 1.2 to 1.7 allow us to reject with >95% confidence the null hypothesis that the observed increases were due to random occurrence. The elevated seismicity was most intense during the first 24 hr (>10 times the average prior rate) but continued above background level for 25 days (at the 95% confidence level) in most areas. We conclude that the increased seismicity was triggered by the Denali fault earthquake, which occurred more than 3000 km from the study region. High peak dynamic stresses of 0.12 to 0.35 MPa that occurred during the passage of the Love waves are consistent with the interpretation of triggering. The peak dynamic stresses were estimated by measuring peak vector velocities at 43 recording sites, 37 of which were relatively new strong-motion stations of the Advanced National Seismic System. The triggered events ranged in magnitude (M (sub c) and/or M (sub L) ) from less than 0 to 3.2 and were widely distributed across the state, primarily in seismically active regions. In contrast to many previously published observations of remotely triggered seismicity, the majority of the triggered earthquakes did not occur near Quaternary volcanic vents or in areas of magma-related geothermal activity. In several areas the triggered seismicity was spatially clustered (more than five earthquakes each separated by <5 km). Double-difference relative relocations for the earthquakes in three of these clusters indicate that most, but not all, of the triggered events were spatially separated from source zones of prior seismicity during 2000-2002. Focal mechanisms for the two largest triggered events have northeast- to northwest-trending tension axes, which are unusual for the region where they occurred. The temporal decay of the triggered activity was similar to that of Utah aftershock sequences and can be described by the modified Omori's law with a p-value of 0.6 to 0.7. The frequency-magnitude distribution of the triggered earthquakes is also similar to that of Utah aftershocks and, for the study area as a whole, can be described by the Gutenberg-Richter relation with a b-value of 0.81+ or -0.16. These similarities between the triggered seismicity and Utah aftershock sequences suggest the possibility that the initiation and development of both could result from the same causative mechanisms.

We inverted teleseismic P waveforms using a pulse-stripping method for multiple time windows with different focal mechanisms and derived composite source models. According to our results, the 2002 Denali fault earthquake began with initial thrusting (M (sub w) 7.3) along a 40-km-long segment of the north-northwest-dipping Susitna Glacier fault and later ruptured a 300-km-long segment along the Denali and Totschunda faults with a right-lateral strike-slip mechanism (M (sub w) 7.7). In contrast, the 2001 Kunlun fault earthquake nucleated near an extensional step-over with a subevent pair consisting of 30-km-long strike-slip (M (sub w) 6.9) event and 40-km-long normal (M (sub w) 6.8) faulting event and later ruptured a 350-km-long segment along the Kunlun fault with a left-lateral strike-slip mechanism (M (sub w) 7.7). Both earthquakes propagated primarily unilaterally to the east and released most of their energy along slip patches (asperities) far from the hypocenter locations. We find that both the Denali fault and Kunlun fault earthquakes had high-average rupture velocities of 3.2 km/sec and 3.4 km/sec, respectively. We also compared the source properties of these two earthquakes with other strike-slip earthquakes. For scaling purposes, large strike-slip earthquakes were classified as interplate, oceanic intraplate, or continental intraplate events. By using this classification the Denali fault and Kunlun fault earthquakes have an interplate signature that suggests overall weak faulting.

The results indicate that analysis of Coulomb stress transfer from the dominant earthquake in a region is a potentially powerful tool in assessing time-varying earthquake hazard. Modeled Coulomb stress increases on the northern Denali and Totschunda faults from the great 1964 earthquake coincide with zones that ruptured in the 2002 Denali fault earthquake, although stress on the Susitna Glacier thrust plane, where the 2002 event initiated, was decreased. A southeasterly-trending Coulomb stress transect along the right-lateral Totschunda-Fairweather-Queen Charlotte trend shows stress transfer from the 1964 event advancing slip on the Totschunda, Fairweather, and Queen Charlotte segments, including the southern Fairweather segment that ruptured in 1972. Stress transfer retarding right-lateral strike slip was observed from the southern part of the Totschunda fault to the northern end of the Fairweather fault (1958 rupture). This region encompasses a gap with shallow thrust faulting but with little evidence of strike-slip faulting connecting the segments to the northwest and southeast. Stress transfer toward failure was computed on the north-south trending right-lateral strike-slip faults in the Gulf of Alaska that ruptured in 1987 and 1988, with inhibitory stress changes at the northern end of the northernmost (1987) rupture. The northern Denali and Totschunda faults, including the zones that ruptured in the 2002 earthquakes, follow very closely (within 3%), for about 90 degrees , an arc of a circle of radius 375 km. The center of this circle is within a few kilometers of the intersection at depth of the Patton Bay fault with the Alaskan megathrust. This inferred asperity edge may be the pole of counterclockwise rotation of the block south of the Denali fault. These observations suggest that the asperity and its recurrent rupture in great earthquakes as in 1964 may have influenced the tectonics of the region during the later stages of evolution of the Denali strike-slip fault system.

We compare models, derived from seismic reflection and refraction surveys acquired in 1986 and 1987, to laboratory measurements of seismic velocities for typical metamorphic rocks exposed along the profiles. Our model for the 1986 seismic reflection profile indicates a 5-km-wide low-velocity zone in the upper 1 km of the Denali fault zone, which we interpret as fault gouge. Deeper refractions from our 1987 line image a 40-km wide, 5-km-deep low-velocity zone along the Denali fault and nearby associated fault strands, which we attribute to a composite damage zone along several strands of the Denali fault zone and to the obliquity of the seismic line to the fault zone. Our velocity model and other geophysical data indicate a nearly vertical Denali fault zone to a depth of 30 km. Aftershocks of the 2002 Denali fault earthquake and our velocity model provide evidence for a flower structure along the fault zone consisting of faults dipping toward and truncated by the Denali fault. Wide-angle reflections indicate that the crustal thickness beneath the Denali fault is transitional between the 60-km-thick crust beneath the Alaska Range to the south, and the extended, 30-km-thick crust of the Yukon-Tanana terrane to the north.

This earthquake, located 330 km to the west of the Yukon-Alaska border, generated 260 reports of shaking and other "unusual effects" to distances of 3500 km across western Canada. Felt intensity for this earthquake ranged from V at communities in the Yukon closest to the epicenter (about 350 km distance), IV across much of the Yukon Territory (distances of 350 to 750 km), III across much of northern British Columbia, to II in southern British Columbia and Alberta (about 2400 km distance). In many instances, people reported feeling nauseous or seasick and having trouble standing. The long-period ground motions generated by this earthquake (displacements greater than + or -10 cm were recorded in the Yukon) caused water to spill from swimming pools, generated seiches in lakes and rivers, and affected wells (instances of dirty well water) to distances of 3500 km across western Canada.

We use a combination of local seismic and Global Positioning System (GPS) data for our kinematic inversion and find that the slip distribution of this event is characterized by three major asperities on the Denali fault. The rupture nucleated on the Susitna Glacier thrust fault, and after a pause, propagated onto the strike-slip Denali fault. Approximately 216 km to the east, the rupture abandoned the Denali fault in favor of the more southwesterly directed Totschunda fault. Three-dimensional dynamic models of this event indicate that the abandonment of the Denali fault for the Totschunda fault can be explained by the Totschunda fault's more favorable orientation with respect to the local stress field. However, a uniform tectonic stress field cannot explain the complex slip pattern in this event. We also find that our dynamic models predict discontinuous rupture from the Denali to Totschunda fault segments. Such discontinuous rupture helps to qualitatively improve our kinematic inverse models. Two principal implications of our study are (1) a combination of inverse and forward modeling can bring insight into earthquake processes that are not possible with either technique alone, and (2) the stress field on geometrically complex fault systems is most likely not due to a uniform tectonic stress field that is resolved onto fault segments of different orientations; rather, other forms of stress heterogeneity must be invoked to explain the observed slip patterns.

This study adopts the theory and methodology of Poliakov et al. (2002) and Kame et al. (2003), in which it was shown that the propensity of the rupture path to follow a fault branch is determined by the preexisting stress state, branch angle, and incoming rupture velocity at the branch location. Here we check that theory on the Denali-Totschunda rupture process using 2D numerical simulations of processes in the vicinity of the branch junction. The maximum compression direction with respect to the strike of the Denali fault near the junction has been estimated to range from approximately 73 degrees to 80 degrees . We use the values of 70 degrees and 80 degrees in our numerical simulations. The rupture velocity at branching is not well constrained but has been estimated to average about 0.8 c (sub s) throughout the event. We use 0.6 c (sub s) , 0.8 c (sub s) , 0.9 c (sub s) , and even 1.4 c (sub s) as parameters in our simulations. We simulate slip transfer by a 2D elastodynamic boundary integral equation model of mode II slip-weakening rupture with self-chosen path along the branched fault system. All our simulations except for 70 degrees and 0.9 c (sub s) predict that the rupture path branches off along the Totschunda fault without continuation along the Denali fault. In that exceptional case there is also continuation of rupture along the Denali fault at a speed slower than that along the Totschunda fault and with smaller slip.

We use five interferograms, constructed using radar images from the Canadian Radarsat-1 satellite, to map the surface deformation at the western end of the fault rupture. Additional geodetic data are provided by displacements observed at 40 campaign and continuous Global Positioning System (GPS) sites. We use the data to determine the geometry of the Susitna Glacier fault, thrusting on which initiated the DFE, and to determine a slip model for the entire event that is consistent with both the InSAR and GPS data. We find there was an average of 7.3+ or -0.4 m slip on the Susitna Glacier fault, between 1 and 9.5 km depth on a 29 km long fault that dips north at 41+ or -0.7 degrees and has a surface projection close to the mapped rupture. On the Denali fault, a simple model with large slip patches finds a maximum of 8.7+ or -0.7 m of slip between the surface and 14.3+ or -0.2 km depth. A more complex distributed slip model finds a peak of 12.5+ or -0.8 m in the upper 4 km, significantly higher than the observed surface slip. We estimate a geodetic moment of 670+ or -10X10 (super 18) N m (M (sub w) 7.9), consistent with seismic estimates. Lack of preseismic data resulted in an absence of InSAR coverage for the eastern half of the DFE rupture. A dedicated geodetic InSAR mission could obviate coverage problems in the future.

These data and aftershock seismicity, jointly interpreted, reveal the crustal structure of the right-lateral-slip Denali fault and the eastern Alaska Range orogen, as well as the relationship between this structure and seismicity. North of the Denali fault, strong seismic reflections from within the Alaska Range orogen show features that dip as steeply as 25 degrees north and extend downward to depths between 20 and 25 km. These reflections reveal crustal structures, probably ductile shear zones, that most likely formed during the Late Cretaceous, but these structures appear to be inactive, having produced little seismicity during the past 20 years. Furthermore, seismic reflections mainly dip north, whereas alignments in aftershock hypocenters dip south. The Denali fault is nonreflective, but modeling of MT, gravity, and magnetic data suggests that the Denali fault dips steeply to vertically. However, in an alternative structural model, the Denali fault is defined by one of the reflection bands that dips to the north and flattens into the middle crust of the Alaska Range orogen. Modeling of MT data indicates a rock body, having low electrical resistivity (>10 Omega .m), that lies mainly at depths greater than 10 km, directly beneath aftershocks of the Denali fault earthquake. The maximum depth of aftershocks along the Denali fault is 10 km. This shallow depth may arise from a higher-than-normal geothermal gradient. Alternatively, the low electrical resistivity of deep rocks along the Denali fault may be associated with fluids that have weakened the lower crust and helped determine the depth extent of the aftershock zone.

Such strain offsets and microseismicity were not recorded at other borehole strain sites along the San Andreas fault system in California. The Long Valley offsets were recorded on borehole strainmeters at three sites around the western part of the caldera that includes Mammoth Mountain--a young volcano on the southwestern rim of the caldera. The largest recorded strain offsets were -0.1 microstrain at PO on the west side of MM, 0.05 microstrain at MX to the southeast of MM, and -0.025 microstrain at BS to the northeast of MM with negative strain extensional. High sample rate strain data show initial triggering of the offsets began at 22:30 UTC during the arrival of the first Rayleigh waves from the Alaskan earthquake with peak-to-peak dynamic strain amplitudes of about 2 microstrain corresponding to a stress amplitude of about 0.06 MPa. The strain offsets grew to their final values in the next 10 min. The associated triggered seismicity occurred beneath the south flank of MM and also began at 22:30 UTC and died away over the next 15 min. This relatively weak seismicity burst included some 60 small events with magnitude all less than M = 1. While poorly constrained, these strain observations are consistent with triggered slip and intrusive opening on a north-striking normal fault centered at a depth of 8 km with a moment of 10 (super 16) N m, or the equivalent of a M 4.3 earthquake. The cumulative seismic moment for the associated seismicity burst was more than three orders of magnitude smaller. These observations and this model resemble those for the triggered deformation and slip that occurred beneath the north side of MM following the 16 October 1999 M 7.1 Hector Mine, California, earthquake. However, in this case, we see little post-event slip decay reflected in the strain data after the Rayleigh-wave arrivals from the Denali fault earthquake and onset of triggered seismicity did not lag the triggered deformation by 20 min. These observations are also distinctly different from the more widespread and energetic seismicity and deformation triggered by the 1992 M 7.3 Landers earthquake in the Long Valley caldera. Thus, each of the three instances of remotely triggered unrest in Long Valley caldera recorded to date differ. In each case, however, the deformation moment inferred from the strain meter data was more than an order of magnitude larger than the cumulative moment for the associated triggered seismicity.

These waves generate a secondary slip pulse trailing the rupture front, but manifest almost entirely in ground motion perpendicular to the fault in the near-source region. We construct a spontaneously propagating rupture model exhibiting these features and use it to explain ground motions recorded during the 2002 Denali fault earthquake at pump station 10, located 3 km from the fault. We show that the initial pulses on both the fault normal and fault parallel components are due to the supershear stress release on the fault, whereas the later-arriving fault normal pulses result from the trailing subshear slip pulse on the fault.

Soils are the primary terrestrial repository for carbon, so minor changes in the balance between belowground carbon storage and release could have major impacts on greenhouse gases. Soil fauna, roots, fungi, and microbes interact with mineral and organic matter to process soil carbon. Studies have been hampered by the difficulty of observing processes beneath the earth's surface, but advances in science and technology are improving our ability to understand belowground ecosystems.

The sorption rate of Eu was initially low, but significantly increased at pH>4. The sorption density of Eu species on a silica surface was approximately 1.58X10 (super -7) mol/m (super 2) when the dissolved Eu species were completely sorbed onto silica-water interfaces at pH = approximately 5.8. The sorbed Eu species at pH<6 is aquo Eu (super 3+) , which is sorbed onto silica-water interfaces as an outer-sphere complex at pH<5, but may be sorbed as an inner-sphere bidentate complex at 5100 km) than observed in any other part of the East African Rift south of the Afar Depression and preserves evidence of bimodal effusive and pyroclastic activity over the past 6.5 Ma. These volcanic materials are associated with sediments from numerous fluvio-lacustrine depositional systems and have been utilized to provide absolute age control on abundant vertebrate taxa, including important homind fossils such as Ardipithecus kadabba, Ardipithecus ramidus, Australopithecus afarensis, Australopithecus garhi, Homo erectus, and Homo sapiens idaltu. The combined geologic and fossil evidence suggests that the broad nature of the rift floor and episodic volcanic and tectonic activities confined to different portions of the middle Awash region created multiple ecological sectors that were inhabited by different species of vertebrate animals during rift evolution. The 6.5 Ma volcanic record is dominated by distal silicic fallout deposits, some widespread throughout northeast Africa and the adjoining ocean basins, with identified or postulated sources within the Ethiopian volcanic province. Local middle Awash region sources are responsible for substantial basaltic input, including major effusive activity between 5 to 5.5 Ma and <3.9 Ma and major strombolian and phreatomagmatic activity between 4.2 to 4.4 Ma and 5.5 to 6 Ma. While many of the silicic tephra contain chemically homogeneous glass, multiple glass populations suggestive of eruption from zoned magma chambers are commonly observed, particularly in the 4.5, 2.5, and <1 Ma time periods. Moreover, three very distinctive mixed magma explosive eruptions are documented at 3.85, 4.4, and 5.6 Ma. The timing of these eruptions corresponds to heightened regional/local basaltic magmatism, which may in turn be linked to episodes of increased tectonic activity and marginal basin development in the transition region between the northern Main Ethiopian and Afar rifts. We will present a chronostratigraphically controlled geochemical summary of the Middle Awash volcanic record and discuss the primary magmatic and tectonic controls on this volcanism.

A parallel finite element groundwater flow model is developed using Metis for mesh partitioning and Aztec for parallel iterative solution; solute transport is solved via random walk particle tracking, also parallelized. A finite element grid is generated using Lagrit to represent the conductivity map with 424,217 nodes and 845,208 elements. A geological framework model is developed based on stratigraphic analysis; numerical, analytical and stochastic methods are used to estimate the effective conductivity (K*) and macro-dispersivity (A) in flow/transport simulations. Using up-scaling, the "scale-effect" in K* is also addressed. We conclude that stochastic model prediction of K* becomes more accurate when a local statistical homogeneity is identified. K* exhibits "scale effect" due to heterogeneity; asymptotic values may be reached after data support exceeds the correlation length. This implies that K* for a hydrostratigraphic layer may only be obtained based on large-scale tests that incorporate flow effects on the order of the correlation length. Simple averaging based on core-scale measurements can lead to severe errors. For chosen boundary conditions, the hydraulic head of the framework model based on K* computed with periodic boundary conditions gives the best approximation to the reference heads computed with all conductivity information. Numerical tracer tests in the heterogeneous model indicate that A depends on the initial plume size/shape and the magnitude of local dispersion. Within a basin with multi-scale conductivity heterogeneity, the groundwater velocity is statistically non-stationary, accordingly, macro-dispersivity experiences fluctuations indicating alternate plume expansion and contraction during its migration.

In the Southwestern US, climate variability and landscape heterogeneity lead to strong gradients in hydrological processes, which in turn impact land-atmosphere interactions, ecological dynamics, biogeochemical cycles and geomorphic change. This complexity presents a fundamental challenge to our understanding of hydrogeology, one that is best addressed through long-term, systematic field and remote-sensing observations and numerical-model investigations. In this talk, we will present our plans to study the interaction of climate-landscape-vegetation and water using a nested set of instrumented sites within the upper Rio Grande, a continental-scale semiarid watershed. This complex watershed extends from the snow-dominated headwater basins in San Juan Mountains of southern Colorado, through the Chihuahuan Desert in New Mexico, Texas and Mexico, to the desert valley alluvial basins southeast of El Paso, Texas. As part of the Consortium of Universities for the Advancement of Hydrologic Science, Inc. (CUAHSI) plan for a network of Long-Term Hydrologic Observatories (LTHOs), the Upper Rio Grande would represent the combination of mountain landscapes, semiarid to arid alluvial basin aquifers and riparian corridors that are characteristic of the Western United States. We will describe existing hydrologic, ecologic and atmospheric measurement infrastructure in the watershed and discuss plans for integrating these into a coherent network that provides a core set of scientific data products for the hydrogeologic community. Data products generated by the upper Rio Grande LTHO will also aid in the testing of coupled numerical models of the atmosphere-surface-groundwater system applied at high resolution over the region. The upper Rio Grande presents a unique opportunity to test many hydrogeologic hypothesis concerning how hydrological processes, such as surface-groundwater interactions, runoff response, solute transport and reactivity, and ecological function, scale with variations in climate and landscape gradients.

The overlap with important geochemical processes has not been broadly evaluated. Carbonate precipitation from multiphase (subcritical H2O and supercritical CO2) fluid-rock reactions was evaluated in a series of experiments conducted in a flexible cell hydrothermal apparatus. In one experiment, a 5.5M NaCl brine-rock system was reacted for 32 days to approach steady state, then injected with supercritical CO2 and allowed to react an additional 45 days. In a separate experiment, the brine-rock system reacted for 77 days without supercritical CO2. In a third experiment, the rock was reacted with 5.5M Mg-NaCl brine for 59 days. Supercritical CO2 was then injected and the system allowed to react an additional 80 days. In all experiments, arkose (microcline + oligoclase + qtz + bt) plus illite-rich shale were part of the reactive system. The brines present a range of reaction potential among rock, brine, and supercritical CO2. On one hand, carbonate may readily precipitate from Mg-rich brine containing aqueous carbonate ion buffered by coexisting supercritical CO2 (Kaszuba et al., 2003). On the other, Na-rich brine, initially devoid of divalent cations, can only derive the cations needed for carbonate precipitation by reaction with silicates. Magnesite precipitated in the Mg-NaCl brine-supercritical CO2-rock experiment whereas magnesite and siderite precipitated in the NaCl brine-supercritical CO2-rock system. Magnesite crystals in both experiments are large, up to a few mm in length, and occur as individual grains and splays. Euhedral magnesite precipitated in Mg-NaCl brine, indicating equilibrium growth. Pitted crystal faces of magnesite in the NaCl brine experiment indicate disequilibrium and are interpreted as dissolution of early-formed magnesite. Siderite occurs as individual crystals, 200-250 mm in diameter, on shale. Euhedral texture, indicative of equilibrium, is interpreted as precipitation of siderite after early-formed magnesite. Occurrence of pitted magnesite and euhedral siderite may represent a paragenetic sequence for carbonates. This sequence is not predicted by geochemical models, indicating complexity of geochemical reactions among supercritical CO2, brine, arkose, and shale.

The geology at the VZRP consists of fractured basalt, interbedded with sedimentary material and overlain by some 20 m of alluvium. The vadose zone is approximately 150 m thick at the VZRP, with perched zones at the base of the alluvium, and at the basalt/interbed contacts. A percolation pond consisting of two cells, each approximately 5776 m (super 2) , provides a means of introducing water into the system. Twenty-three vadose zone wells and instrumented boreholes are in place within the VZRP. The vadose zone wells and boreholes are distributed in nested sets that each consist of a shallow monitoring well completed at the alluvium/basalt contact, a deeper monitoring well completed at an interbed at approximately 37 m depth, and an instrument package containing tensiometers, lysimeters, gas-sampling ports, water-content sensors, and thermocouples inserted at depths ranging from 12 to 146 m. In July 2003, we began directing water at 4100 m (super 3) /day into the northern cell of the pond that had not been used for the previous nine months. For the first 140 minutes of infiltration a tracer mixture containing two non-reactive tracers (bromide ion and 2,4-difluorobenzoic acid) was added to the discharge, thus initiating a long-term tracer test. We collected water samples from monitoring wells and suction lysimeters every two to four hours for roughly one month, and at longer intervals for another two months. Transport distances from the pond to the sampling locations are on the order of 100-200 m. Based on the bromide breakthrough curves and preliminary modeling we estimate seepage velocities of 5-10 m/day. Multiple peaks in the breakthrough curves, together with fast arrival times and variable mass recovery indicate that the water followed a number of different flow paths.

In an attempt to better understand the controlling mechanisms of subsurface fluid transport, a system of monitoring instruments was installed in boreholes around the perimeter of newly constructed percolation ponds and along an ephemeral river approximately one kilometer to the north. This instrumented region has been designated as the Vadose Zone Research Park (VZRP). INTEC facility-water discharge to the new percolation ponds began in October 2002 at a rate of approximately a million gallons per day. Continuous monitoring of subsurface hydraulic properties at the VZRP since May 2002 coupled with periodic tracer injections suggest that subsurface flow is controlled by the presence of preferential flow paths and extreme contrasts in hydraulic conductivity between sedimentary interbeds and fractured basalt flows. In addition, the observations show that perched water does not dissipate rapidly in the absence of local recharge and that it may extend tens of meters both laterally and vertically from the source area. In contrast to these observations, the most prevalent current conceptual model for fluid transport in the vadose zone at the INEEL adopts diffuse type flow and assumes that perched water dissipates rapidly in the absence of local recharge. Continued monitoring and transport studies at the VZRP can contribute significantly to the understanding of fluid transport at the INEEL and similar sites throughout the country. Efforts are currently underway to establish the VZRP as a collaborative, multidisciplinary field research center that can be utilized to develop an improved conceptual model for fluid and contaminant transport in heterogeneous, complex vadose zones.

The weir was built after the Cerro Grande fire to mitigate off-site movement of potentially contaminated sediment, which was expected to increase dramatically due to watershed damage further up the drainage. After construction, concerns about downward transport through fractured basalt from temporarily ponded water behind the weir prompted the Laboratory to install three monitoring boreholes. In conjunction with the monitoring plan, a bromide tracer test was designed to study transport. Prior to the summer rainy season of 2002, a solution of potassium bromide was sprayed onto the ponding area behind the weir. Bromide sampling was initiated in May 2002 and is ongoing. An 86 m vertical borehole with water sampling ports at 4 screened intervals (from 27 m to 82 m) provides high resolution temporal data of bromide concentration within the unsaturated zone beneath the weir. Data from the 4 sampling ports show that the initial transport to depth is quite rapid (60m in a few days), and that three observed ponding events have had a large impact on subsurface transport. Additionally, the data show that the bromide concentrations at all depths peaked within 1/2 year and are now decreasing. Simulations of bromide breakthrough are used to constrain the effective basalt porosity (0.001-0.01) and permeability (1e-12--1e-11 m2).

AN - 51580249; 2006-048556 AB - Distributed strike-slip shear is difficult to detect, particularly where shear is accommodated by vertical-axis rotation of fault blocks. Declination anomalies in paleomagnetic data have become the principal evidence used to detect such rotations. The >700 sq km Cerros del Rio volcanic field (CdRVF) in northern New Mexico lies within the Rio Grande Rift and overlaps the boundary between Espanola and Santa Domingo Basins. The CdRVF comprises mostly flat-lying lava and pyroclastic deposits erupted from multiple basaltic to dacitic volcanic centers between 2.7 Ma and 1.1 Ma. We have sampled CdRVF units for paleomagnetic analysis at 51 sites distributed over the field. Extensive alternating-field demagnetization was required to isolate primary magnetization in many of these sites due to overprints from past lightning strikes. A mean direction of 49 sites is D=346.3 degrees , I=51.5 degrees , a95=4.5 degrees , k=22. These data should average geomagnetic secular variation; they are distributed subequally between Gauss-chron normal-polarity sites and younger mostly reversed-polarity sites of the Matuyama chron and they sample units erupted from at least 12 volcanic centers. Compared to an expected direction calculated from a 0-Ma pole of Besse and Courtillot (2003), the CdRVF mean direction has a significantly counterclockwise (CCW) declination (-9.0 degrees + or - 6.3 degrees ), whereas the inclination is slightly shallow (4.2 degrees + or - 3.6 degrees ). The CCW declination anomaly confirms earlier findings by Brown and Golombek (1986) based on fewer paleomagnetic data; they attributed the declination anomaly to CCW rotation of the entire Espanola Basin. Alternatively, CCW rotation may be linked to local shear developed as interaction increased between faults of the Espanola and Santo Domingo Basins during known, late-stage narrowing of Rio Grande rifting.

Fundamentally, microscopic processes accomplish all macroscopic deformation. There are only a few distinct grain-scale deformation mechanisms; each one dominates at different P,T conditions, produces characteristic microstructures, and has a different form of constitutive relation between stress and strain or strain rate. Understanding the different mechanisms informs the most fundamental questions in our discipline. Interpretation of the microstructures preserved in deformed rocks allows us to infer the physical conditions and history of deformation. Knowledge of rock rheology allows us to predict the deformation style and rock strength in different tectonic settings, and provides critical input to geodynamics questions. The study of deformation mechanisms, microstructures and rheology allows students to correlate grain-scale features and processes to those developed at hand sample, outcrop and regional scales, and to confront how deformation rates relate to rock strength at different depths in the crust. Students trained to recognize and understand the actual processes of both brittle and ductile deformation are better able to critically analyze the bulk behavior of rocks in different geologic settings. To facilitate the incorporation of deformation mechanisms and microstructures into structural geology courses, our working group has developed short teaching modules on critical concepts (e.g., cataclastic flow, diffusion and pressure solution, dislocation creep) that can be incorporated into existing courses during discussion of related topics (e.g., faults, foliations, folds). These modules include instructor's notes, key diagrams, annotated photos, possible handouts, and ideas for class or lab demonstrations and activities. The modules and supplemental resources (e.g., animations, analogs, articles) can be found at http://serc.carleton.edu/NAGTWorkshops/structure04. Additional contributions to this resource bank from all geoscientists are welcome.

In addition, other magnesium sulfates hydrates (sanderite - MgSO4.2H2O, Starkeyite - MgSO4.4H2O, pentahydrite - MgSO4.5H2O) have been identified as efflorescent salts in limited localities in the United States, Chile, and Germany. Significant attention has been recently given to Mg-sulfate salts as they are believed to be a widespread cementing agent in Martian soils. Most studies examine only the possible occurrences of epsomite, hexahydrite, and kieserite at the Martian surface, on the assumption that the other MgSO4 hydrates are unstable or metastable. To investigate the possibility that the other hydrates are stable at conditions not common on the Earth's surface, various hydrate forms of MgSO4 were placed into ovens at 50 degrees and 75 degrees C over saturated salt solutions to control humidity. Samples chosen for this study include anhydrous MgSO4, reagent monohydrate MgSO4 (non-kieserite structure), synthesized kieserite, synthesized starkeyite, and hexahydrite. Equilibration times varied from 10 to 30 days. Although hexahydrite is a common hydrate on the Earth's surface, the largest stability fields were for kieserite and starkeyite at elevated temperatures. Although sanderite formed in several experiments, its stability field, if thermodynamically stable, appears to be rather limited. To date, we were only able to form pentahydrite as a metastable phase during rehydration of amorphous MgSO4 hydrate. In addition, we were able to form MgSO4-hydrates whose identities in X-ray diffraction analysis are uncertain, as there were no matching phases in the International Centre for Diffraction Data database. Results of this study show that MgSO4 hydrates other than epsomite, hexahydrite, and kieserite can be stable (especially starkeyite) but not at conditions normally encountered on the Earth's surface. Unlike the sharp hexahydrite/epsomite transition, the stability fields for the other MgSO4 hydrates show considerable overlap, which is probably indicative of both metastability and kinetic limitations. As would be expected, the stable form of the MgSO4.nH2O series is significantly dependent on both RH and temperature.

Elevations of the contact between the units extracted from a digital elevation model of the area are used to construct a paleotopographic surface on top of the Otowi member. The Tshirege member filled a relatively rugged topography that developed on the Otowi member during the approximately 400,000 years between eruptions of the Valles Caldera; local relief is generally on the order of 20 to 30 m, although along the Rio Cebolla, relief is approximately 100 m. The base of the Tshirege member generally dips toward the southwest, away from a drainage divide north of the map area and away from the Valles Caldera rim. Elevations of the base of the Tshirege member range from 2680 to 2740 m in the north central part of the area and along the topographic rim of the caldera to about 2500 m near Fenton Lake. Some of the paleocanyons cut into the Otowi member in the western Jemez Mountains follow the general trend of modern canyons, but are offset to the west; however, many of the paleocanyons trend more to the southwest compared to the trend of modern drainages. In the northern and western Jemez Mountains, little sediment is preserved between the two tuff members, but fluvial gravels are found in the southwestern and southern part of the range. In places, the fluvial gravel is composed of material recycled out of the underlying Otowi member. Elsewhere, the fluvial gravel includes rounded clasts of locally derived Tertiary Paliza Canyon andesite and basalt and Permian sandstone. Epiclastic sediment and tephra deposits of the Cerro Toledo interval are present between the tuffs on the Pajarito Plateau in the eastern Jemez Mountains. The paleotopography on the Otowi in the Seven Springs area, combined with these observations from elsewhere in the Jemez Mountains, are used to provide a snapshot of the landscape around the Valles Caldera 1.2 million years ago.

Highest Mg and S abundances were measured in indurated soil ("duricrust"). Data from Viking, Pathfinder, and the Mars Exploration Rovers Spirit and Opportunity indicate widespread presence of approximately 10 wt% Mg-sulfate salt (anhydrous weight basis) as a cementing agent in soil. Other cations (e.g. K, Fe) are likely associated with sulfate in other associations, as in the Opportunity rover's observation of jarosite by Moessbauer analysis at Meridiani Planum. Nevertheless, the correlation between Mg and S in soils persists, as seen in alpha-proton X-ray spectrometry data collected from a shallow trench dug by the Spirit rover on sol 140 at Gusev Crater. Naturally occurring members of the MgSO4.H2O series on Earth are epsomite (MgSO4.7H2O), hexahydrite (MgSO4.6H2O), and kieserite (MgSO4.H2O) but many other hydration states are known. Given the very different environment of Mars, the MgSO4.nH2O minerals common on Earth may not be common on Mars and forms rare on Earth may play a more important role on Mars. In particular, experiments indicate that amorphous MgSO4.nH2O may occur under very low RH conditions on Mars. We have examined products of magnesium sulfate brines allowed to crystallize at low pressure with and without admixed minerals and rocks to form simulated duricrust. Our experiments show that at low RH (<1%), brine crystallization proceeds from precipitation of epsomite through transformation to hexahydrite, but the stable phase, kieserite, does not form. Instead, hexahydrite becomes amorphous on timescales of hours to days at approximately 1-5 torr total pressure. The epsomite crystal morphologies persist despite dehydration and loss of crystal structure. When Mg-sulfate cements are formed under vacuum with synthetic regolith materials such as clays, zeolites, or palagonites, the product is a duricrust-like material in which Mg-sulfate salt forms initially as hexahydrite but soon becomes amorphous. If allowed to rehydrate the duricrust expands; the expanded form is retained even if the duricrust is again desiccated. These salt-cemented products may have mechanical properties similar to Martian duricrust.

AN - 85301127; pmid-15532630 AB - A new class of simple, highly efficient, cylindrical acoustic concentration devices has been developed based upon cylindrical (or near cylindrical) geometries [Kaduchak et al., Rev. Sci. Instrum. 73, 1332-1336 (2002)] for aerosol concentration applications. The concentrators are constructed from single PZT tubes driven at or near the breathing mode resonance. Acoustic concentration of aerosols is performed within the tube cavity. It has been found that slight modifications to the cylindrical cavity geometry can significantly increase the collection efficiency and assist in precise particle positioning. This paper analyzes the theoretical framework for the acoustic concentration of particles in these devices for various geometrical perturbations. The cavity geometries studied are (1) hollow cylindrical piezoelectric tube, (2) hollow piezoelectric tube with an inner concentric solid cylinder insert, (3) a hollow piezoelectric tube with a concentric elliptic insert which breaks the circular-cylindrical symmetry, and (4) a hollow elliptic cylindrical piezoelectric tube. It is shown that breaking the circular symmetry within the cavity localizes the particles in small spatial regions within the cavity. This localization of particles may be very useful in applications requiring aerosol collection or particle stream positioning.

The treatments were conducted in two adjacent boreholes within interbedded sands and shales of the Upper Cotton Valley formation. The microearthquakes were induced within narrow horizontal bands that correspond to the targeted sandstone layers. Events throughout all the treatments show strike-slip faulting occurring uniformly along vertical fractures trending close to maximum horizontal stress direction. These events are consistent with the reservoir's prevalent natural fractures, known to be isolated within the sands and trending subparallel to the expected hydraulic fracture orientation. When this uniform fracture system was activated exclusively, the detected shear deformation, measured as the moment release per unit volume of fluid injected, was constant, independent of various fluid viscosities and flow rates used. Within the base of the Upper Cotton Valley formation, anomalous event counts and moment release occurred within dense clusters that delineate bends or jogs in the fracture zones. The mechanisms are also strike-slip, but the fault planes are more favorably oriented for failure. The dense clusters show location patterns diverging in time, suggesting the expulsion of fluids from compressive fault jogs. Fluid flow forced by the adjacent slip-induced loading appears to initially extend the treatments, but the loading also tends to lock up and concentrate stress at the jogs, as evident by fewer but larger events populating the structures as treatments progress. As a result, effective drainage lengths from the boreholes may be shorter than would be inferred from the seismicity extending past the jogs. These high-moment asperities are similar to dense patches of seismicity observed along creeping sections of the San Andreas fault, where they have been attributed to localized zones of strength or stress concentration, surrounded by larger regions undergoing stable, aseismic slip. This similarity, plus large moment deficits in terms of volume injected, suggests a large component of aseismic slip is induced by the Cotton Valley treatments.

This includes ground-based photographic and radiometer data as well as infrasound and seismic data from this very significant bolide event (Spurny et al. 2002, 2003). We have also used these data to model the entry of Neuschwanstein, including the expected dynamics, energetics, panchromatic luminosity, and associated fragmentation effects. In addition, we have calculated the differential efficiency of acoustical waves for Neuschwanstein and used these values to compare against the efficiency calculated using available ground-based infrasound data. This new numerical technique has allowed the source height to be determined independent of ray tracing solutions. We have also carried out theoretical ray tracing for a moving point source (not strictly a cylindrical line emission) and for an infinite speed line source. In addition, we have determined the ray turning heights as a function of the source height for both initially upward and downward propagating rays, independent of the explicit ray tracing (detailed propagation path) programs. These results all agree on the origins of the acoustic emission and explicit source heights for Neuschwanstein for the strongest infrasonic signals. Calculated source energies using more than four different independent approaches agree that Neuschwanstein was certainly <500 kg in initial mass, given the initial velocity of 20.95 km/s, resulting in an initial source energy < or =0.0157-0.0276 kt TNT equivalent (4.185X10 (super 12) J). Local source energies at the calculated infrasonic/seismic source altitudes are up to two orders of magnitude smaller than this initial source energy.

Results are presented of controlled humidity and XRD identifications of the Mg SO (sub 4) phases at 298 K; relative humidity and stability fields are figured for all three minerals. Kieserite converts to hexahydrite or epsomite with increase in humidity and reverts to kieserite on desiccation. The results indicate that Mg sulphate salts may retain sufficient H (sub 2) O to explain at least some of the observations found by the space craft. Because of the likelihood of the ready alteration of these phases on removal from their location, in situ mineralogical determinations are essential when this becomes feasible.

For a comparison of forests in two contrasting climates we also evaluated trends in delta super(13)C sub(R) from a wet 20-year-old Douglas-fir (Pseudotsuga menziesii) plantation located near the Pacific Ocean. Intraannual variability in delta super(13)C sub(R) was greater than 8.0ppt at both sites, was highest during autumn, winter, and spring when rainfall was abundant, and lowest during summer drought. The delta super(13)C sub(R) of the dry pine forest was consistently more positive than the wetter Douglas-fir forest (mean annual delta super(13)C sub(R): -25.41ppt vs. -26.23ppt, respectively, P=0.07). At the Douglas-fir forest, delta super(13)C sub(R)-climate relationships were consistent with predictions based on stomatal regulation of carbon isotope discrimination ( Delta ). Soil water content (SWC) and vapor pressure deficit (vpd) were the most important factors governing delta super(13)C sub(R) in this forest throughout the year. In contrast, delta super(13)C sub(R) at the pine forest was relatively insensitive to SWC or vpd, and exhibited a smaller drought-related enrichment ( similar to 2ppt) than the enrichment observed during drought at the Douglas-fir forest ( similar to 5ppt). Groundwater access at the pine forest may buffer canopy-gas exchange from drought. Despite this potential buffering, delta super(13)C sub(R) at the pine forest was significantly but weakly related to canopy conductance (G sub(c)), suggesting that delta super(13)C sub(R) remains coupled to canopy-gas exchange despite groundwater access. During drought, delta super(13)C sub(R) was strongly correlated with soil temperature at both forests. The hypothesis that canopy-level physiology is a critical regulator of delta super(13)C sub(R) was supported; however, belowground respiration may become more important during rain-free periods.

Quantitative data are increasingly required for engineering dose calculations and for space weather science. However, the design of some energetic particle detectors can be severely constrained. Background effects must be accurately modeled in such cases to extract quantitative information. In particular, bremsstrahlung radiation from electrons impacting the detector and the satellite often dominates the background noise. Numerical tools are presented here to calculate total bremsstrahlung effects in energetic electron detectors. The calculations are illustrated for the low-energy particle detector of current Global Positioning System satellites.

AN - 66771033; 15297015 AB - The effect of beryllium (Be) exposure has been extensively studied in patients with chronic beryllium disease (CBD). CBD patients carry mutated MHC class II alleles and show a hyperproliferation of T cells upon Be exposure. The exact mechanism of Be-induced T-cell proliferation in these patients is not clearly understood. It is also not known how the inflammatory and suppressive cytokines maintain a balance in healthy individuals and how this balance is lost in CBD patients. To address these issues, we have initiated cellular and biochemical studies to identify Be-responsive cytokines and other cellular markers that help maintain a balance in healthy individuals. We have established an immune cell model derived from a mixture of peripheral blood mononuclear cells (PBMCs) and dendritic cells (DCs). In this article, we demonstrate that pro-inflammatory cytokine IL6 shows decreased release whereas suppressive cytokine IL10 shows enhanced release after 5-10 h of Be treatment. Furthermore, the Be-specific pattern of IL6 and IL10 release is dependent upon induction of threonine phosphorylation of a 45 kDa cytosolic protein (p45), as early as 90 min after Be treatment. Pharmacological inhibition of phosphatidylinositol 3' kinase (PI3'K) by wortmannin and p38 mitogen-activated protein kinase (MAPK) by SB203580 reveal that PI3'K mediates Be-specific p45 phosphorylation and IL6 release, whereas p38 MAPK regulates the release of IL6 and IL10 and the phosphorylation of p45 independent of metal-salt treatment. While the IL10 and IL6 release pathways are uncoupled in these cells, they are linked to phosphorylation of p45.

AN - 51794113; 2004-076545 AB - Kinetic studies are reported of the effect of methanol on the rate of formation of CO (sub 2) - and CH (sub 4) -hydrates by means of in situ time-of-flight neutron powder diffraction. The experiments were carried out at temperatures ranging from 200 to 250 K and pressures up to 7 Mpa. The samples were prepared from mixtures of ground, deuterated ice and deuterated methanol (up to 20 vol%), which were transformed in situ into CO (sub 2) - or CH (sub 4) -hydrates by pressurizing the systems with the corresponding gas. The observed rates of formation of hydrates are orders of magnitude higher than the rate of formation from pure deuterated ice under the same pressure and temperature conditions. Glycols and alcohols, methanol in particular, are long known as thermodynamic inhibitors of hydrate formation. Our study indicates that methanol can also act as a kinetic promoter for the formation of gas hydrates. Preliminary data suggest that the kinetics also depend strongly on concentration and the isotopic composition.

The phases of HFOPs recorded at any given retinal location drift randomly over time, but regions activated by the same stimulus tend to remain phase locked with approximately zero lag, whereas regions activated by spatially separate stimuli are typically uncorrelated. Based on retinal anatomy, we previously postulated that HFOPs are mediated by feedback from a class of axon-bearing amacrine cells that receive excitation from neighboring ganglion cells-via gap junctions-and make inhibitory synapses back onto the surrounding ganglion cells. Using a computer model, we show here that such circuitry can account for the stimulus specificity of HFOPs in response to both high- and low-contrast features. Phase locking between pairs of model ganglion cells did not depend critically on their separation distance, but on whether the applied stimulus created a continuous path between them. The degree of phase locking between spatially separate stimuli was reduced by lateral inhibition, which created a buffer zone around strongly activated regions. Stimulating the inhibited region between spatially separate stimuli increased their degree of phase locking proportionately. Our results suggest several experimental strategies for testing the hypothesis that stimulus-specific HFOPs arise from axon-mediated feedback in the inner retina.

Some of these concerns are animal-related accidents that can result in human injuries and fatalities, property damage, and a loss of an economically viable resource (game). We analyzed animal-vehicle accident data with respect to time, season, location, and species for accidents occurring on LANL property and analyzed site characteristics of accident hotspots. We observed a significantly greater number of vehicle-elk (Cervus elaphus) accidents during winter compared to summer and spring and a greater number of elk and mule deer (Odocoileus hemionus) vehicle accidents during late afternoon and evening hours compared to morning and afternoon hours. We estimated a cost of $136,500 per year associated with animal-vehicle accidents occurring on LANL property (excluding medical costs). Slope and vegetation height were the best predictors of the status of an area as a hotspot or a control site. These data will be used in public education efforts and to develop mitigation measures to reduce the potential for accidents.

J Comput Phys 2004; 194(2):773-94] to efficiently incorporate existing direct measurements of the log hydraulic conductivity. We first decompose the conditional log hydraulic conductivity Y = lnK sub(s) as an infinite series on the basis of a set of orthogonal Gaussian standard random variables zeta sub(i). The coefficients of this series are related to eigenvalues and eigenfunctions of the conditional covariance function of the log hydraulic conductivity. We then write head as an infinite series whose terms h super((n)) represent the head contribution at the nth order in terms of capital sigma sub(Y), the standard deviation of Y, and derive a set of recursive equations for h super((n)). We assume that h super((n)) can be expressed as infinite series in terms of the products of n Gaussian random variables. The coefficients in these series are determined by substituting decompositions of Y and h super((m)), m < n, into those recursive equations. We solve the conditional mean head up to fourth-order in capital sigma sub(Y) and the conditional head covariances up to third-order in. The higher-order corrections for the conditional mean flux and flux covariance can be determined directly from the higher-order moments of the head, using Darcy's law. We compare the results from the KLME approach against those from Monte Carlo (MC) simulations and the conventional first-order moment method. It is evident that the KLME approach with higher-order corrections is superior to the conventional first-order approximations and is computationally more efficient than both the Monte Carlo simulations and the conventional first-order moment method.

Although the spatial distribution of WEH does not correspond to the current distribution of water vapor in the atmosphere, several terrestrial analogs indicate that dynamics of atmospheric circulation during periods of higher obliquity prior to the present epoch can qualitatively account for the observed WEH distribution.

AN - 66794754; 15315364 AB - Adulteration of vegetable oil is of concern for both commercial and health reasons. Compositional based fingerprints can potentially reveal both the oil source and its possible adulteration. Here, electrospray ionization (ESI) Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) resolves and identifies literally thousands of distinct chemical components of commercial canola, olive, and soybean oils, without extraction or other wet chemical separation pretreatment. In negative-ion ESI FT-ICR MS, the acidic components of soybean oil are easily distinguished from those of canola and olive oil based on relative abundances of C(18) fatty acids, whereas olive oil differs from canola and soybean oil based on relative abundances of tocopherols. In positive-ion ESI FT-ICR MS, the three oils are readily distinguished according to the relative abundances of di- and triacylglycerols with various numbers of double bonds in the fatty acid chains. We demonstrate the detection of soybean oil as an adulterant of olive oil, based on relative abundances of members of each of several chemical families. We suggest that the detailed chemical compositions of vegetable oils can be used to characterize them and to detect and identify adulterants.

AN - 66767044; 15291520 AB - We report the rational design of ligands that selectively bind beryllium. We selected two ligands to design Be based on binding polynulear species with a Be-O-Be motif: 2-hydroxyisophthalic acid (HIPA) and 2,3-dihydroxybenzoic acid (DHBA). All previous work has focused on BeL or BeL2 species. The HIPA and DHBA have extremely high binding constants of 17.5 and 18.4, respectively. These ligands outcompete chromotropic acid, which has one the highest binding constants for Be reported in the literature for a simple BeL species. The binding of the second Be to form the Be-O-Be motif is so strong that polynuclear species predominates in solution down to micromolar concentrations. Both ligands show a fluorescence response in the presence of beryllium, making them promising candidates for fluorescence-based sensors. In the case of HIPA, there is a fluorescence shift, and in the case of DHBA, the presence of beryllium turns on the fluorescence by removing two OH bonds that otherwise lead to nonradiative decay. The most dramatic result is that DHBA selectively binds Be in the presence of a metal cocktail containing a 50-fold excess of Al, Fe, Cr, Cu, Zn, Cd, and Pb. This is the first time that such selectivity for beryllium has been demonstrated.

The motivating question is from a drug discovery process, where after some gene expression analysis experiment, we wish to understand the overall effect of some cell treatment or condition by identifying 'where' in the GO the differentially expressed genes fall: 'clustered' together in one place? in two places? uniformly spread throughout the GO? 'high', or 'low'? In order to address this need, we view bio-ontologies more as combinatorially structured databases than facilities for logical inference, and draw on the discrete mathematics of finite partially ordered sets (posets) to develop data representation and algorithms appropriate for the GO. In doing so, we have laid the foundations for a general set of methods to address not just the categorization task, but also other tasks (e.g. distances in ontologies and ontology merger and exchange) in both the GO and other bio-ontologies (such as the Enzyme Commission database or the MEdical Subject Headings) cast as hierarchically structured taxonomic knowledge systems.

Therefore, measurement of physical and chemical properties of reclaimed minesoils (RMS) is essential for understanding the process of soil restoration. This study was designed to assess soil quality of two reclaimed sites and two nearby undisturbed sites in Jackson and Vinton counties, Ohio. Three different rates of fertilizers applied annually to the RMS at Jackson and Vinton County sites from 1979-1994 were: no fertilizer (FL1), 112-25-46 kg NPK ha-1 (FL2), and 224-50-92 kg NPK ha-1 (FL3). Bulk and core samples were obtained for only 0- to 10-cm depth for undisturbed (unmined) soil (UMS) and for 0 to 10 and 10 to 20 cm for RMS. A comparison within UMS and RMS showed that water-stable aggregation and mean weight diameter of aggregates (MWDs) were significantly higher for UMS than RMS for both sites (P 6.4 and was favorable for root development and biomass production at both reclaimed sites. No significant differences in several soil properties between UMS and RMS showed that fertility treatments improved the soil quality of RMS.

The thickness and abundance of the stromatolitic horizons increase up the section. In the siliciclastic portion of the section, a very poor and taxonomically impoverished assemblage of benthic foraminifers (Jadammina, Nonion, Haynesina, Astrononion and Eponides) is recorded. It is typical for a shallow water marsh or lagoon environment with a lowered salinity. Accordingly, the brackish conditions prevailing during gypsum precipitation in East Crimea continued afterwards, although at the end of evaporite deposition the basin became desiccated and then it was rapidly reflooded by brackish water. The impoverished biota and the occurrence of microbialites in the Ptashkino section indicate extremely unfavourable conditions for most living organisms during the deposition of both the terrigenous and carbonate beds. The water salinity thus was probably not only lowered but also anomalous in composition if compared to normal marine water. The occurrence of carbonate stromatolitic horizons is probably related to the periodic shallowing of the basin caused by a drop of the lake water table driven by climatic factors. The resulted changes allowed for a growth of the bizarre microbial-serpulid communities that gave birth to most of the stromatolites. In Karaganian time, the Eastern Paratethys was a huge lake isolated from the Tethys. This lake responded to any climatic fluctuation that in turn might lead to water level oscillations. In humid climate periods, the lake could be open with a surface outflow and, when it was drier, it could be a closed system without surface outflow. Gypsum evaporites and stromatolitic carbonates are clear evidence of strong evaporation in a dry climate that probably induced water level fall in the whole basin. However, all the time the environmental conditions were predominantly brackish, even during gypsum precipitation as suggested by the chemical composition of fluid inclusions in gypsum. Similar conditions may be expected in other evaporite-hosted, predominantly brackish basins, such as some Messinian basins of the eastern Mediterranean, where some evaporites were deposited in the oligohaline to mesohaline conditions typical of the Lago Mare deposits.

We first linearize the steady state unsaturated flow equations by Kirchhoff transformation and solve the moments of the transformed variable up to second order, in terms of the standard deviations of log hydraulic conductivity Y=ln(K sub(s)) and of the log pore size distribution parameter beta =ln( alpha ). In addition, we also give solutions for the mean and variance of the unsaturated hydraulic conductivity. The analytical solutions of moment equations are validated via Monte Carlo simulations.

It has a similar structure to a well-known formula for the field outside any spherically symmetric conductivity profile. For a radial dipole, the field on the inside has a very simple expression. A symmetry argument is given as to why the field of a radial dipole vanishes outside a spherical conductor. Illustrative plots of the magnetic field are presented for a radial and a tangential dipole; the slope of the tangential component of the magnetic field is discontinuous at the surface of the sphere. A spherical conductor having three concentric regions is discussed; and we also derive an analytic formula for the magnetic field inside a homogeneous infinite half space.

This method consists of synthesizing a highly fluorescent nucleic acid reporter molecule using a sequence of the target as a template. Synthesis of the reporter molecule is accomplished by hybridizing a short complementary oligonucleotide primer to the target and extending the reporter using a polymerase and free nucleotides. One of these nucleotides is partially labeled with a fluorophore. The reaction sample is then flowed through the capillary cell of a single molecule detector. Detection of the reporter signifies the presence of the target being sought. Under carefully selected conditions, fluorescence from the reporter molecule is much stronger than that of the free nucleotide background over the detection time. We have derived practical equations that allow us to determine an optimal range of values for the relative reporter and free-nucleotide concentrations. This method allows for the rapid, direct detection of individual targets at femtomolar concentrations without the use of an amplification procedure, such as the polymerase chain reaction.

Underground mine fires and burning culm banks ignited by natural causes or human error are responsible for atmospheric pollution, acid rain, perilous land subsidence, the destruction of floral and faunal habitats, human fatalities, and increased coronary and respiratory diseases. Some of the oldest and largest coal fires in the world occur in China, the United States, and India. Techniques used to fight coal fires include slurry and ash injection, surface and tunnel sealing, aqueous foam technology, remote sensing, and computer software. Elusive, unpredictable, or cost prohibitive coal fires may burn indefinitely, choking the life out of a community and its environs while consuming a valuable natural resource.

Its prior applications dealt with flows in porous media whose internal compositions are amenable to simple parameterizations. This study provides a means for probabilistic reconstruction of boundaries between geologic facies. We apply our general approach to multiple data sets to reconstruct highly permeable zones within an aquitard in the Bologna (Italy) aquifer system and demonstrate how it can be used in conjunction with RDD.

The log-transformed saturated hydraulic conductivity f(x) and the soil pore size distribution parameter alpha (x) are assumed to be normal random functions with known covariances. We decompose f(x) and alpha (x) as infinite series in a set of orthogonal normal random variables by the Karhunen-Loeve expansion and expand the pressure head as polynomial chaos with the same set of orthogonal random variables. The perfectly correlated and uncorrelated cases between f(x) and alpha (x) are studied. By using the Karhunen-Loeve expansion of the input random parameters, polynomial chaos decomposition of pressure head, and the perturbation method, the saturated-unsaturated flow equation and the corresponding initial and boundary conditions are represented by a series of partial differential equations in which the dependent variables are the deterministic coefficients of the polynomial chaos expansion. Once the partial differential equations are solved subsequently by a numerical method, the random representation of pressure head is obtained by combining the deterministic coefficients obtained and the random variables from the Karhunen-Loeve expansion of the input random functions. The moments of pressure head and water content are determined directly from the random representation of the pressure head. We demonstrated the applicability of the proposed KL-based stochastic model with some examples of unsaturated and saturated-unsaturated flow in two dimensions, and compared the results with those from the moment-based stochastic model. It is shown that the KL-based models are more computationally efficient than the conventional moment-based models.

The technique requires no chromatographic separation, is able to distinguish 18 different compound classes (e.g., neutral nitrogen, carboxylic acids and oxygenates), and can identify approximately 14,000 distinct masses by ultra-high mass resolution and mass accuracy. We previously studied three crude oils from different geological origins [Organic Geochemistry 33 (2002b) 743-759]. Here, we expand our research by comparing two source-equivalent Smackover oils of different levels of thermal maturity. We observe clear differences in the distribution of NSO compound classes, types (number of rings plus double bonds within a class), and number of alkyl carbons. With increasing thermal stress, the relative amount of sulfur and oxygen containing compounds decreases, condensation and aromatization of the polar cores increase, and the number of alkyl carbons decreases, reflecting the distribution of saturated hydrocarbons.

It has been expanded to account for effects of high relative humidities. Adsorption capacity competition between water vapor and organic vapor is largely explained by mutual exclusion of adsorption volume of the activated carbon. The Dubinin/Radushkevich equation is used to describe the adsorption isotherms of both water and organic vapors. Effects of relative humidity and adsorbed water on adsorption rates are described by an empirical correlation with breakthrough times. The dynamic natures of adsorption and competition are incorporated using an expanding zone model with displaced water rollup. The complete model has been tested and verified with published and unpublished data from many sources.

Here, we extend the traditional uses of topographic analysis to evaluate the role played by topography in the distribution of regional-scale biodiversity in the south-western USA. An important aspect of our study is its ability to provide a way to quantify characteristics of the topographic fabric and to construct predictive models that can be used to test hypotheses that relate topography and biodiversity. South-western USA region of the North American Cordillera. Our approach begins with a quantitative analysis of the topography and the construction of a predicted biodiversity map based on measurable topographic quantities: organization, roughness, slope aspect, grain orientation and mean elevation. We then make a quantitative comparison between the predicted and observed biodiversity, based on the assumption that land-cover diversity is a plausible measure of regional-scale biodiversity. Land-cover information used for this study was collected as part of the U.S.G.S. global land cover characteristics (GLCC) project and is derived from satellite (AVHRR) imagery. To a first order, the predicted regional-scale biodiversity based on our topographic model shows a good correlation with the observed biodiversity (as estimated from the land-cover diversity). Our model overestimates the biodiversity in many parts of the Colorado Plateau, Rio Grande Rift, and the low desert regions of the Southern Basin and Range, suggesting that in these provinces a biodiversity estimate based solely on topography is an over-simplification. However, much of the Madrean Archipelago and Sierra Madre provinces, which are centres of high biodiversity in this region, show excellent agreement between the observed and predicted biodiversity. While we acknowledge that many other factors in addition to topography have an important influence on biodiversity (particularly on a local scale), we conclude that topography plays a primary role in the regional to continental-scale biodiversity, particularly in regions characterized by insular mountain fabrics.

These background samples are collected from five river stations and four reservoirs located throughout northern New Mexico and southern Colorado. Analyses include super(3)H, super(90)Sr, super(137)Cs, total U, super(238)Pu, super(239, 240)Pu, super(241)Am, gross alpha, gross beta, and gross gamma radioactivity. Surprisingly, there are no federal or state regulatory standards in the USA that specify how to compute background radioactivity values on sediments. Hence, the sample median (or 0.50 quantile) is proposed for this background because it reflects central data tendency and is distribution-free. Estimates for the upper limit of background radioactivity on river and reservoir sediments are made for sampled analytes using the 0.95 quantile (two-tail). These analyses also show that seven of ten analytes from reservoir sediments are normally distributed, or are normally distributed after a logarithmic or square root transformation. However, only three of ten analytes from river sediments are similarly distributed. In addition, isotope ratios for super(137)Cs/ super(238)Pu, super(137)Cs/ super(239, 240)Pu, and super(239, 240)Pu/ super(238)Pu from reservoir sediments are independent of clay content, total organic carbon/specific surface area (TOC/SSA) and cation exchange capacity/specific surface area (CEC/SSA) ratios. These TOC/SSA and CEC/SSA ratios reflect sediment organic carbon and surface charge densities that are associated with radionuclide absorption, adsorption, and ion exchange reactions on clay mineral structures. These latter ratio values greatly exceed the availability of background radionuclides in the environment, and insure that measured background levels are a maximum. Since finer-grained reservoir sediments contain larger clay-sized fractions compared to coarser river sediments, they show higher background levels for most analytes. Furthermore, radioactivity values on reservoir sediments have remained relatively constant since the early 1980s. These results suggest that clay contents in terrestrial sediments are often more important at concentrating background radionuclides than many other environmental factors, including geology, climate and vegetation. Hence, reservoirs and floodplains represent ideal radionuclide sampling locations because fine-grained materials are more easily trapped here. Ultimately, most of these differences still reflect spatial and temporal variability originating from global atmospheric nuclear weapons testing and disintegration of nuclear- powered satellites upon atmospheric reentry.

AN - 72026947; 15004206 AB - Cadmium (Cd(2+)) is one of well-known toxic heavy metal ions. To gain a global understanding how Cd(2+) affects cells at the molecular level, we systematically studied the cellular response of the fission yeast Schizosaccharomyces pombe to Cd(2+) using our integrated proteomic strategy of amino acid-coded mass tagging (AACT) and liquid chromatography-tandem mass spectrometry. Our proteome-wide investigation unequivocally identified 1133 S. pombe proteins. Of which, the AACT-based quantitative analysis revealed 106 up-regulated and 55 down-regulated proteins on the Cd(2+) exposure. The most prevalent functional class in the up-regulated proteins, approximately 28% of our profile, was the proteins involved in protein biosynthesis, showing a time-dependent biphasic expression pattern characteristic with rapid initial induction and later repression. Most significantly, 27 proteins functionally classified as cell rescue and defense were up-regulated for oxygen and radical detoxification, heat shock response, and other stress response. Furthermore, the large precursor sequence coverage of our AACT approach allowed us to unequivocally identify and quantitate different isozymes for glutathione S-transferase, which have close similarity in their amino acid sequence. Our quantitative dataset also showed that 80% of the up-regulated proteins found in the S. pombe response were different from those in the Saccharomyces cerevisiae response. The function of some of the key identifications was validated through biochemical assays. It is very interesting that the induction of cysteine synthase expression was not observed in our study, although it has been proven as a critical enzyme to supply free cysteines for the enhancing synthesis of Cd(2+)-sequestering molecules such as glutathione and phytochelatins in plants and some yeasts. Our quantitative proteomic result instead suggested that, as an alternative mechanism for the detoxification of Cd(2+), S. pombe produced significantly higher level of inorganic sulfide to immobilize cellular Cd(2+) as a form of CdS nanocrystallites capped with glutathione and/or phytochelatins.

The method consists of synthesizing a fluorescent reporter molecule using a polymerase extension reaction and labeled nucleotides. The fluorescent reporter products are analyzed in a laser-based single-molecule detection system. We have applied this method to the detection of pUC19 and Bacillus anthracis DNA targets. We expect that this method will have applications in rapid detection and identification of DNA from pathogens as well as other sources, and that it will be used for processing of large number of samples in a short period of time.

Another defect of traditional rem meters is a poor high-energy response above 10 MeV, which makes them unsuitable for applications at high-energy accelerator facilities. Proton Recoil Scintillator-Los Alamos (PRESCILA) was developed as a low-weight (2 kg) alternative capable of extended energy response, high sensitivity, and moderate gamma rejection. An array of ZnS(Ag) based scintillators is located inside and around a Lucite light guide, which couples the scintillation light to a sideview bialkali photomultiplier tube. The use of both fast and thermal scintillators allows the energy response function to be optimized for a wide range of operational spectra. The light guide and the borated polyethylene frame provide moderation for the thermal scintillator element. The scintillators represent greatly improved versions of the Hornyak and Stedman designs from the 1950's, and were developed in collaboration with Eljen Technology. The inherent pulse height advantage of proton recoils over electron tracks in the phosphor grains eliminates the need for pulse shape discrimination and makes it possible to use the PRESCILA probe with standard pulse height discrimination provided by off-the-shelf health physics counters. PRESCILA prototype probes have been extensively tested at both Los Alamos and the German Bureau of Standards, Physikalisch-Technische Bundesanstalt. Test results are presented for energy response, directional dependence, linearity, sensitivity, and gamma rejection. Initial field tests have been conducted at Los Alamos and these results are also given. It is concluded that PRESCILA offers a viable, ergonomically superior, alternative to traditional rem meters that is effective for a wide range of neutron fields. The probe is capable of excellent sensitivity (40 counts per minute per microSv h-1 for 241AmBe) and extended energy response to beyond 20 MeV. Directional response is uniform (+/-15%) over a wide range of energies. Response linearity has been characterized to over 20 mSv h-1. Gamma rejection is effective in gamma fields up to 2 mSv h-1. The PRESCILA technology has been commercialized and is now offered under license by Ludlum Measurements, Inc.

AN - 71934344; 15147923 AB - Perceptions about general environmental problems, governmental spending for these problems, and major concerns about the US Department of Energy's Los Alamos National Laboratory (LANL) were examined by interviewing 356 people attending a gun show in Albuquerque, New Mexico. The hypothesis that there are differences in these three areas as a function of ethnicity was examined. We predicted that if differences existed, they would exist for all three evaluations (general environmental problems, government spending, and environmental concerns about LANL). However, this was not the case; there were fewer ethnic differences concerning LANL. Hispanics rated most general environmental problems higher than Whites and rated their willingness to expend federal funds higher than Whites, although all groups gave a lower score on willingness than on concern. Further, the congruence between these two types of ratings was higher for Hispanics than for others. In general, the concerns expressed by subjects about LANL showed few ethnic differences, and everyone was most concerned about contamination. These data indicate that Hispanics attending a gun show are equally or more concerned than others about environmental problems generally but are not more concerned about LANL. The data can be useful for developing future research and stewardship plans and for understanding general environmental problems and their relationship to concerns about LANL. More generally, they indicate that the attitudes and perceptions of Hispanics deserve increased study in a general population.

Results indicate that uranyl triscarbonate-like adsorption complexes dominate at U(VI) solution concentrations <500 mu M, whereas the formation of U(VI) hydroxide and carbonato precipitates is observed at higher concentrations, consistent with isotherm data and aqueous speciation calculations. The EXAFS data indicate weak splitting in the equatorial O shell of the U(VI) adsorption complexes, which may indicate that the adsorption complexes are bound in an inner-sphere fashion at the calcite surface, although no Ca backscattering could be positively identified. The luminescence data indicate the presence of at least two adsorption complexes that change proportion with U(VI) loading. One species, dominating at low-surface coverage, is the uranyl triscarbonate complex. A second species is observed at higher surface loadings with a luminescence spectrum that is intermediate between the triscarbonate species found at the lowest loadings and uranyl incorporated into bulk polycrystalline calcite. The combined EXAFS and luminescence data indicate that the U(VI) adsorption complexes forming at the calcite surface are triscarbonate-like complexes, with a change in interaction with calcite surface sites as the surface loading increases, and the formation of U(VI) hydroxide/carbonato precipitates at high concentrations. Consequently, multiple uranyl species are likely to exist at the calcite surface during interaction of U(VI)-containing waters in the near-surface environment. Furthermore, complex sorption/desorption behavior and kinetics may be associated with differing stabilities of sorbed U(VI) species in calcite-containing materials.

We used the anelastic liquid approximation with Earth-like material parameters. The usual variable-viscosity approach in mantle-convection models is the assumption of a temperature dependence only. The resulting thermal boundary layers are included in our model also, but an additional viscosity profile of the interior mantle was derived: The Birch-Murnaghan equation was employed to derive the Gruneisen parameter and other physical quantities as a function of depth from observational values provided by PREM. We computed the melting temperature and a new mantle viscosity profile, called eta3, using the Gruneisen parameter, Lindemann's law and some solid-state physics considerations. The new features of eta3 are a high-viscosity transition layer with rather high viscosity gradients at its boundaries, a second low-viscosity layer beginning under the 660-km discontinuity, and a strong viscosity increase in the central parts of the lower mantle. The rheology is Newtonian but it is supplemented by a viscoplastic yield stress, sigma (sub y) . A viscosity-level parameter, r (sub n) , and sigma (sub y) have been varied. For a medium-sized Rayleigh-number-yield-stress area, eta3 generates a stable, plate-tectonic behavior near the surface and simultaneously thin sheet-like downwellings in the depth. Outside this area, three other types of solution were found. Not only the planforms but also the evolution of the Rayleigh number, the reciprocal Urey number, the Nusselt number, the surface heat flow, etc., have been studied. We repeated this investigation with two very different basic viscosity profiles, etaKL5a and etaKM, of other authors. A comparison reveals that eta3 facilitates the generation of surface plates and thin sheet-like downwellings in the depth considerably more than etaKL5a or even etaKM. The presence of two internal low-viscosity layers is obviously conducive for plateness and thin sheet-like downwellings. For an infinite yield stress, the thin cold sheet-like downwellings are reticularly connected. However, the distribution of the downwellings is more Earth-like if a realistic yield stress is added.

We used the Aangstroem method on cylindrical samples in multianvil apparatus at pressures up to 20 GPa and temperatures up to 1373 K. Because of the fine polycrystallinity of the specimens ( approximately 30-40 mu m or less), there is strong scattering/absorption of light and suppression of radiative transport so that the lattice vibrational component is the dominant heat transfer mode. Lattice thermal conductivities were calculated from the thermal diffusivity results using heat capacity and equation of state data. Olivine thermal conductivities are consistent with previous results obtained at 1 atm [e.g. J. Am. Ceramic Soc. 38 (1954) 107; J. Geophys. Res. 77 (1972) 6966; Science 283 (1999) 1699]. Thermal conductivity increases by approximately 30% at the transition from olivine to wadsleyite (corresponding to the 410 km discontinuity) and a further, but smaller, increase may occur at the transition from wadsleyite to ringwoodite. For each of these phases, lattice conductivity closely follows a T (super -1/2) dependence on temperature T [Phys. Rev. 119 (1960) 507; J. Geophys. Res. 79 (1974) 703; Brown, 2002]. If such a dependence applies to other silicates and complex crystals, there should be a useful way to estimate conductivities at high temperatures from room temperature measurements.

Gravitational settling from the outer convective zone (OCZ) into the radiative core is viewed as the only solar modification of solar-nebula isotopic compositions to affect all elements. Evidence for gravitational settling is indirect, as observations are presently less precise than the predictions of <10 per mil effects for the isotopes of solid-forming elements. Additional solar modification has occurred for light isotopes (D, Li, Be, B) due to nuclear destruction at the base of the convection zone, and due to production by nuclear reactions of photospheric materials with high-energy particles from the corona. Isotopic fractionation of long-term average samples of solar wind has been suggested by theory. There is some evidence, though not unambiguous, indicating that interstream (slow) wind is isotopically lighter than high-speed wind from coronal holes, consistent with Coulomb drag theories. The question of fractionation has not been clearly answered because the precision of spacecraft instruments is not sufficient to clearly demonstrate the predicted fractionations, which are <30 per mil per amu between fast and slow wind for most elements. Analysis of solar-wind noble gases extracted from lunar and asteroidal soils, when compared with the terrestrial atmospheric composition, also suggests solar-wind fractionation consistent with Coulomb drag theories. Observations of solar and solar-wind compositions are reviewed for nearly all elements from hydrogen to iron, as well as the heavy noble gases. Other than Li and the noble gases, there is presently no evidence for differences among stable isotopes between terrestrial and solar photosphere compositions. Although spacecraft observations of solar-wind isotopes have added significantly to our knowledge within the past decade, more substantial breakthroughs are likely to be seen within the next several years with the return of long-exposure solar-wind samples from the Genesis mission, which should yield much higher precision measurements than in situ spacecraft instruments.

This conversion provided an opportunity to compare regolith moisture patterns of zero-order watersheds under native chaparral with those under nonnative veldt grass (Ehrharta calycina Sm.). We collected data as a function of vegetation type and watershed element to test the hypothesis that conversion from chaparral to grass altered water distribution in the vadose zone as a result of changes in the physical environment, including rooting depth and soil horizonation. Patterns in vadose zone water distribution during the dry season, including soil water potential and residual flux, were significantly different in converted areas, reflecting the different rooting habits of the two vegetation types. In chaparral areas, there was no significant change in soil water potential between the surface and the 150-cm depth; soil water potential was consistently below -1.5 MPa, reflecting the extensive root system. In grass areas, soil water potential was most negative close to the surface, where grass roots were most abundant. Plant available water was present below the 100-cm depth, suggesting that recharge to groundwater may occur under grass in average or wetter years. Under both vegetation types, the largest differences in residual water fluxes were near the soil-weathered rock contact. However, there was a significant relation between minor differences in fluxes and soil horizon boundaries, confirming the effects of vegetation conversion on soil properties and vadose zone soil water.

Our calculated ground-ice distribution contains improvements over previous work in that we include the effects of the high thermal conductivity of ice-cemented soil at and below the ice table, we include the surface elevation dependence of the near-surface atmospheric humidity, and we utilize new high resolution maps of thermal inertia, albedo, and elevation from Mars Global Surveyor observations. Results indicate that ground ice should be about 5 times shallower than in previous predictions. While results are dependent on the atmospheric humidity, depths are generally between a few millimeters and a few meters with typical values of a few centimeters. Results are also geographically similar to previous predictions with differences due to the higher resolution of thermal inertia and the inclusion of elevation effects on humidity.

Such information is needed to evaluate whether airborne mass of beryllium is the appropriate metric of exposure or alternatively to provide a scientific basis for using information on particle size, surface area, and chemistry to support an improved exposure limit based on bioavailability through the inhalation and dermal routes of exposure. Thus, we used a suite of analytical techniques to characterize aerodynamically size-fractionated beryllium particles and powders that have been associated in epidemiological studies with higher prevalence of CBD. Aerosol particles were sampled from the ventilation systems of production lines for powders of beryllium metal and beryllium oxide and for ingots of copper-beryllium alloy. End product powders from the metal and oxide production lines were also collected. Particles released during production of beryllium metal were found to be complex, having heterogeneous composition, including reactive species such as fluorine. Powders from beryllium metal production were of high purity with only a minor component of beryllium oxide. Both particles and powders from oxide production were high-purity oxide. Particles released during production of copper-beryllium alloy were heterogeneous, being predominantly copper oxides. Thus, all particles and powders contain at least some beryllium in the form of beryllium oxide. These data justify efforts to thoroughly characterize beryllium aerosol properties when performing exposure assessments. The data also suggest that differences in particle chemical composition, size, number, and surface area may influence bioavailability of beryllium and contribute to risk of CBD. However, a scientific basis does not yet exist to replace mass as the current metric of exposure.

AN - 85305237; pmid-15139616 AB - The enrichment of the neon isotopes in a thermoacoustic device is demonstrated. Because the thermal diffusion ratio of neon is small, an apparatus longer than a wavelength was necessary in order to easily observe the separation. The device was modular and extensible, so that arbitrarily large separations could in principle be obtained. The acoustic duct was a series of multiple, identical quarter-wavelength modules with side-branch drivers. In this way, waveforms close to that of a traveling wave were maintained in the duct, despite the high acoustic attenuation caused by the duct's small diameter and large length. The concentrations of the isotopes were measured at one end of the duct using a quadrupole mass spectrometer. For the operating frequency of 227 Hz, the maximum separation gradient obtained was 0.43%/m, and mole fluxes at zero gradient as high as 3 nmol/s were observed. Effects of turbulence, though not observed, are also discussed, and the scaling properties of this method are compared with those of traditional mixture-separation methods.

Flow nonstationarity in the vadose zone may arise from a number of factors. It is useful to develop a systematic approach that incorporates these factors into an uncertainty analysis. We first derive the general forms for solute flux moments. The solute flux moments are associated with one- and two-particle joint probability distribution functions (JPDF). We illustrate our results for certain forms of one-particle and two-particle JPDFs, in which the particle travel time is assumed to be lognormally distributed and the particle transverse displacement normally distributed. In the numerical examples, the Eulerian velocity moments is obtained by solving the head moment equations numerically using a finite-difference method. Our results show that flow nonstationarity has a significant impact on the statistics of solute fluxes and solute breakthrough curves.

Polyethylenimine (PEI) was functionalized with bromo- or chloroacetic acid to give an aminocarboxylate chelating group, which effectively binds lead. The resulting polymer, PEIC, has extraction properties similar to the molecular chelator ethylenediaminetetraacetic acid. A series of studies was done to probe optimum conditions for lead extraction from soils obtained from the Cal-West Superfund site in New Mexico that contained approximately 10,000 ppm of Pb. In batch extraction experiments using polymer functionalized at two different levels, the polymers removed greater than 97% of the lead from the soils. Subsequent experiments demonstrated that the selective extraction of lead could be controlled by varying polymer functionalization levels. Concentration and regeneration of the polymers using ultrafiltration was also demonstrated. Release of lead from the polymer was accomplished by acidification to pH 1 with HCl. Subsequent ultrafiltration allowed recovery of the extractant polymer for reuse.

This estimate increases to 90% during the summer months, and, overall, up to 5% of the drums stored in active treatment, storage, and disposal facilities may be pressurized. The ability to identify pressurized drums in real-time would enhance worker health and safety, reduce the potential for environmental contamination, and minimize property damage. A prototype hand-held drum pressure detection device was field tested at an active Resource Conservation and Recovery Act mixed waste operation using acoustic resonance spectroscopy technology to identify pressurized drums. The waste operation used a drum venting system that measured the actual drum pressure of retrieved drums. Drum venting system data were analyzed to quantify the ability of the drum pressure detection device to correctly identify drums with elevated internal pressure. After 456 drums were measured, the dichotomous pressure data (pressurized vs. nonpressurized) were analyzed. The relationship between the drum venting system and drum pressure detection device pressure data was found to be statistically significant. With alpha and beta values of 0.05, the negative predictive value was 0.94, the positive predictive value was 0.47, the sensitivity was 0.82, and the specificity was 0.77. Although capable of identifying nonpressurized drums, this instrument may not be appropriate for general use. Study results and critical improvements necessary to improve the instrument's predictive value, specificity, and sensitivity are presented.

Few techniques have been able to compete with pulsed-field gel electrophoresis (PFGE), which is capable of discriminating among bacteria at species and strain levels by resolving restriction fragments. However, an ultrasensitive flow cytometer (FCM) developed in our lab has also demonstrated the ability to discriminate bacteria at species and strain levels. The abilities of FCM warrant a quantitative parallel comparison with PFGE to assess and evaluate the accuracy and precision of DNA fragment sizing by both techniques. Replicate samples of Staphylococcus aureus Mu50 were analyzed along with two clinical S. aureus isolates. The absolute fragment sizing accuracy was determined for PFGE (5% plus or minus 2%) and FCM (4% plus or minus 4%), with sequence-predicted Mu50 SmaI fragment sizes used as a reference. Precision was determined by simple arithmetic methods (relative standard deviation for PFGE (RSD sub(PFGE) ) = 3% plus or minus 2% and RSD sub(FCM) = 1.2% plus or minus 0.8%) as well as by the use of dendrograms derived from Dice coefficient-unweighted pair group method with arithmetic averages (UPGMA) and Pearson-UPGMA analyses. All quantitative measures of PFGE and FCM precision were equivalent, within error. The precision of both methods was not limited by any single sample preparation or analysis step that was tracked in this study. Additionally, we determined that the curve-based clustering of fingerprint data provided a more informative and useful assessment than did traditional band-based methods.

Advances in genome analysis technology are providing an unprecedented amount of information about bacterial and viral organisms, and hold great potential for pathogen detection and identification. In this paper, a rational approach to the development and application of nucleic acid signatures is described based on phylogenetically informative sequence features, especially single nucleotide polymorphisms. The computational tools that are available to enable the development of the next generation of microbial molecular signatures for clinical diagnostics and infectious disease surveillance are reviewed and the impact on public health and national security will be discussed.

Gaseous elemental mercury (GEM) and ozone were measured starting from 1998 and 1999, respectively, until August 2002. GEM was measured with a TEKRAN 2735A automatic mercury analyzer based on preconcentration of mercury on a gold trap followed by detection using fluorescence spectroscopy. Ozone was measured by UV absorption. A scatter plot of GEM and ozone concentrations confirmed that also at Station Nord GEM and ozone are linearly correlated during AMDEs. The relationship between ozone and GEM is further investigated in this paper using basic reaction kinetics (i.e., Cl, ClO, Br, and BrO have been suggested as reactants for GEM). The analyses in this paper show that GEM in the Arctic troposphere most probably reacts with Br. On the basis of the experimental results of this paper and results from the literature, a simple parametrization for AMDE was included into the Danish Eulerian Hemispheric Model (DEHM). In the model, GEM is converted linearly to reactive gaseous mercury (RGM) over sea ice with temperature below -4 degree C with a lifetime of 3 or 10 h. The new AMDE parametrization was used together with the general parametrization of mercury chemistry [Petersen, G.; Munthe, J.; Pleijel, K.; Bloxam, R.; Vinod Kumar, A. Atmos. Environ. 1998, 32, 829-843]. The obtained model results were compared with measurements of GEM at Station Nord. There was good agreement between the start and general features periods with AMDEs, although the model could not reproduce the fast concentration changes, and the correlation between modeled and measured values decreased from 2000 to 2001 and further in 2002. The modeled RGM concentrations over the Arctic in 2000 were found to agree well with the temporal and geographical variability of the boundary column of monthly average BrO observed by the GOME satellite. Scenario calculations were performed with and without AMDEs. For the area north of the Polar Circle, the mercury deposition increases from 89 tons/year for calculations without an AMDE to 208 tons/year with the AMDE. The 208 tons/year represent an upper limit for the mercury load to the Arctic.

These measurements help constrain the depth below the surface of the water/magma interaction that cause maar volcanism. Commonly applied measures include the abundance and type of lithic fragments in the tephra, the depth of the crater, well logs, and regional stratigraphy. While most maars show evidence for interaction within a few hundred meters below the Earth's surface within the zone of saturation, maar craters associated with diatreme eruption suggest that interaction can occur at much greater depths in the Earth's crust. Because aquifer pore pressure increases with depth, many researchers have assumed that once pressure exceeds water's critical pressure, interaction ceases to be explosive because steam is not formed. This assumption is incorrect according to results of theoretical and experimental work, which shows the potential for dynamic interaction at confining pressures up to and perhaps exceeding 100 MPa. Even for geopressured aquifers (confined under lithostatic stress), these results suggest that interaction can initiate at maximum depths >4 km, reaching depths perhaps exceeding 10 km. For interaction at great depth, considerations of hydrofracture and host rock brecciation, aquifer thermal and pressure gradients, and seismic response are important in evaluating eruption dynamics. Especially for interactions at great depth, eruptive venting may be delayed or absent. Detailed evaluation of multiphase thermal and fluid dynamics provides methods of formulating hypotheses about the depth (pressure) controls of water/magma interaction. These hypotheses are tested by results of experiments and field observations.

Stress in the upper layer is in-plane tensional and stress in the lower layer is down-dip compressional. The modeled stress field agrees with observations of stress in the Tonga double seismic zone. High shear stress also exists in the slab at depths below the metastable wedge. This stress distribution involves down-dip compression and trench-parallel tension, which agrees with about half of the focal mechanisms in the Tonga slab at depths of 460-690 km. The model supports the idea that at least two possible stress release mechanisms for deep earthquakes may act in the Tonga subducting slab. One, transformational faulting, is restricted to the metastable wedge while the other one acts below the metastable wedge.

Is it super(3)/ sub(4) or super(2)/ sub(3)? This question has been raised before and resolved in favour of super(3)/ sub(4). Like previous ones, recent claims for a value of super(2)/ sub(3) are based almost entirely on basal metabolic rate (BMR) in mammals. Here we compile and analyse a new, larger data set for mammalian BMR. We show that interspecific variation in BMR, as well as field metabolic rates of mammals, and basal or standard metabolic rates for many other organisms, including vertebrates, invertebrates, protists and plants, all scale with exponents whose confidence intervals include super(3)/ sub(4) and exclude super(2)/ sub(3). Our analysis of maximal metabolic rate gives a slope that is greater than and confidence intervals that exclude both super(3)/ sub(4) and super(2)/ sub(3). Additionally, numerous other physiological rates that are closely tied to metabolism in a wide variety of organisms, including heart and respiratory rates in mammals, scale as M super(-1/4). The fact that quarter-power allometric scaling is so pervasive in biology suggests that different allometric relations have a common, mechanistic origin and provides an empirical basis for theoretical models that derive these scaling exponents.

To better interpret species abundance patterns in natural microbial communities, we examined the consequences of three fundamental types of abundance patterns-uniform, geometric, and lognormal distributions. Theoretical communities were constructed based on the three pattern types with 2000 to 20,000 species and 10 super(7) to 10 super(10) individuals. The 'dominant' species (species 1) among models that differed only in pattern type generally varied in abundance by 1 to 3 orders of magnitude. At the extremes among all the models examined, the dominant species comprised as much as 16% and as little as 0.005% of the total community. Analysis of the models and comparison with seven published surveys suggests that entire soil bacterial communities do not routinely exhibit Preston's cannonical subset of lognormal distributions. Use of the models to evaluate survey limitations showed that common diversity indices are generally sensitive to sample size over the range (50 to 200 clones) commonly used for microbial communities, emphasizing the need to compare surveys of similar size. The results collectively demonstrate that uniform, geometric, and lognormal distributions have profoundly different experimental and ecological consequences. Further, defined abundance models provide a simple quantitative tool for evaluating abundance patterns in clone libraries (even small ones) from natural communities.

This polymorph is the first observed silicate composed of face-sharing polyhedra and it has a density similar to stishovite. Sterical constraints on the bond angles induce an intrinsic disorder of Si positions, such that the Si-coordination is transitional between four- and sixfold. The structure provides a mechanism for this coordination change in silica and other silicates at high temperature that is fundamentally different from mechanisms at 300 K. The new polymorph also illustrates how the face-sharing polyhedra, naturally occurring along previously proposed compression mechanisms for dense silicate melts, can be constructed without inferring unphysically small bond angles.

These data are used to further evaluate the applicability of these nuclides for direct radiometric dating of polar ice. In order to minimize artifacts during sample processing we developed an improved method utilizing ethylenediaminetetraacetic acid (EDTA) to stabilize uranium-series nuclides dissolved in polar ice during ice melting and filtration. Our measurements revealed low uranium-series daughter abundances and large uranium-series ( (super 234) U/ (super 238) U, (super 230) Th/ (super 234) U, (super 226) Ra/ (super 230) Th, (super 231) Pa/ (super 235) U) disequilibria in the filtered <0.05-mu m fraction of these ice samples. Both the long-lived uranium-series disequilibria and (super 10) Be/ (super 36) Cl ratios are most likely recently inherited from precipitation. The short-lived daughter (super 226) Ra is the exception and is enhanced in the <0.05-mu m fraction, presumably due to recoil effects from dust bands present in the ice. Based on a simplified recoil model, ice ages of approximately 30 ka are obtained from our data. Absence of measurable (super 238) U- (super 234) U- (super 230) Th- (super 226) Ra disequilibria in the volcanic dust bands also suggests that ice ages are greater than 10 ka, consistent with recoil-based ages. Our relatively young ice ages can be compared with previously published relatively old terrestrial ages of meteorites from this area and suggests that meteorites at Allan Hills have experienced a multi-stage history of ice accumulation and/or ice flow. Our results also suggest that large uranium-series disequilibria can be inherited from precipitation, which may provide a method for dating clear ice samples.

These, it is suggested, may be due to the complexity of the system, with strong coupling between the electronic and elastic lattice degrees of freedom, leading to self-organized inhomogeneities over these submicroscopic scales. A model presented describes a sub-mu m texture which does not necessarily depend upon fluctuations in charge density even at the atomic scale.

The addition of an electron shuttle did not affect fractionation, suggesting that Fe isotope fractionation may not be related to the kinetics of the electron transfer. Furthermore, in abiotic, anaerobic FeCl sub(2(aq)) experiments in which approximately one-third of Fe(II) sub((aq)) is lost from solution due to adsorption of Fe(II) onto goethite, the delta super(56/54)Fe value of Fe(II) sub((aq)) remaining in solution is shifted by -0.8ppt relative to FeCl sub(2). This finding demonstrates that anaerobic nonbiological interaction between Fe(II) and goethite can generate significant Fe isotope fractionation. Acid extraction of sorbed Fe(II) from goethite in experiments reveals that heavy Fe preferentially sorbs to goethite. Simple mass-balance modeling indicates that the isotopic composition of the sorbed Fe(II) pool is similar to +1.5ppt to +2.5ppt heavier than Fe in the goethite [ similar to 2.7ppt-3.7ppt heavier than aqueous Fe(II)]. Mass balance is also consistent with a pool of heavy Fe that is not released to solution during acid extraction.

We captured 69 male skunks 133 times and 35 female skunks 57 times on 4 12.8-km super(2) plots. Estimates of abundance on plots ranged from 0.10 to 0.71 skunks/km super(2). Annual survival rates were 0.40 in 1994 and 0.48 in 1995. Survival curves did not differ significantly between years. From the 26 recovered carcasses, 50% of skunks died from human-caused trauma. Shooting of skunks around occupied houses was the largest single cause of mortality.

Since 1940 the Greenland coastal stations data have undergone predominantly a cooling trend. At the summit of the Greenland ice sheet the summer average temperature has decreased at the rate of 2.2 degree C per decade since the beginning of the measurements in 1987. This suggests that the Greenland ice sheet and coastal regions are not following the current global warming trend. A considerable and rapid warming over all of coastal Greenland occurred in the 1920s when the average annual surface air temperature rose between 2 and 4 degree C in less than ten years (at some stations the increase in winter temperature was as high as 6 degree C). This rapid warming, at a time when the change in anthropogenic production of greenhouse gases was well below the current level, suggests a high natural variability in the regional climate. High anticorrelations (r = -0.84 to -0.93) between the NAO (North Atlantic Oscillation) index and Greenland temperature time series suggest a physical connection between these processes. The future changes in the NAO and Northern Annular Mode may be of critical consequence to the future temperature forcing of the Greenland ice sheet melt rates.

This study examined the effects of adding ethanol (EtOH) to a 4% Tween 80 (polyoxyethylene (20) sorbitan monooleate) solution used to flush tetrachloroethene (PCE)-contaminated porous media. The influence of EtOH concentration, subsurface layering and scale on flushing solution delivery and PCE recovery was investigated through a combination of experimental and mathematical modeling studies. Results of batch experiments demonstrated that the addition of 2.5%, 5% and 10% (wt.) EtOH incrementally increased the PCE solubilization capacity and viscosity of the surfactant solution, while reducing solution density from 1.002 to 0.986 g/cm super(3). Effluent concentration data obtained from one-dimensional (1-D) column experiments were used to characterize rate-limited micellar solubilization of residual PCE, which was strongly dependent upon flow velocity and weakly dependent upon EtOH concentration. Two-dimensional (2-D) box studies illustrated that minor differences (0.008 g/cm super(3)) between flushing and resident solution density can strongly influence surfactant front propagation. A two-dimensional multiphase simulator, MISER, was used to model the influence of EtOH composition on the aqueous flow field and PCE mass recovery. The ability of the numerical simulator to predict effluent concentrations and front propagation was demonstrated for both 1-D columns and 2-D boxes flushed with EtOH-amended Tween 80 solutions. Results of this study quantify the potential influence of alcohol addition on surfactant solution properties and solubilization capacity, and demonstrate the importance of considering small density variations in remedial design.

A-I, and toxic-shock syndrome toxin TSST-1 act as superantigens to cause overstimulation of the host immune system, leading to the onset of various diseases including food poisoning and toxic shock syndrome. SAgs bind as intact proteins to the DR[alpha]1 domain of the MHC class II receptor and the TcRV[beta] domain from the T cell receptor and cause excessive release of cytokines such as IL-2, TNF-[alpha], and IFN-[gamma], and hyperproliferation of T cells. In addition, different SAgs bind and activate different TcRV[beta] isoforms during pathogenesis of human immune cells. These two properties of SAgs prompted us to design several chimeric DR[alpha]1-linker- TcRV[beta] proteins using different TcRV[beta] isoforms to create chimeras that would specifically inhibit the pathogenesis of SAgs against which they were designed. In this study, we compare the design, interaction, and inhibitory properties of three different DR[alpha]1-linker-TcRV[beta] chimeras targeted against three different SAgs, SEB, SEC3, and TSST-1. The inhibitory properties of the chimeras were tested by monitoring IL-2 release and T cell proliferation using a primary human cell model. We demonstrate that the three chimeras specifically inhibit the pathogenesis of their target superantigen. We performed molecular modeling to analyze the structural basis of the type specificity exhibited by different chimeras designed against their target SAgs, examine the role of the linker in determining binding and specificity, and suggest site- specific mutations in the chimera to enhance binding affinity. The fact that our strategy works equally well for SEB and TSST-1, two widely different phylogenic variants, suggests that the DR[alpha]1-linker-TcRV[beta] chimeras may be developed as a general therapy against a broad spectrum of superantigens released during Staphylococcal infection.

The model does not use flux corrections at the air-sea interface, nor is the ocean "spun up" prior to coupling. When increasing CO (sub 2) at the rate of 1% per year to twice its original level and keeping it constant thereafter, the model responds with a 2 degrees C increase in 200 years in the global mean surface air temperature and a virtually unchanged Atlantic meridional overturning circulation (MOC). Due to the predominantly isopycnic character of HYCOM, geographic details of the 3-D thermohaline circulation in potential density space can be extracted from the model output with relative ease. The analysis confirms that even regional details of the MOC in this experiment are rather insensitive to the climate change brought on by CO (sub 2) doubling. Furthermore, the analysis reveals strong similarities between the simulated and the observed MOC.

The shallow lake formed by early September increased in level by approximately 1 m/month until the creation of artificial drainage in September 2001. Before the eruption, the lake water, initially with initially near-neutral pH, was dominated by meteoric influx and Cl-SO (sub 4) and Cl-HCO (sub 3) hydrothermal waters; peaks in SO (sub 4) and Ca concentrations were due to leaching of anhydrite and aerosol-laden tephra. Magmatic discharge, acidity (pH approximately 2) and rock dissolution peaked in late 1992 during eruption of a lava dome in the crater but shortly after dome growth ceased lake pH increased from 3 to 5.5 and T decreased from 40 to 26 degrees C. Enhanced Cl, Na, K, Li and B and a lowering of concentrations of Mg, Ca, Fe, SO (sub 4) and F up to 1999, along with stable isotope and tritium data, indicate the importance of a dilute hydrothermal input but since then increasing dilution by meteoric water and decreasing T are accompanied by increasing pH. Gas and brine from crater fumaroles and hot springs at present indicate boiling of immature Cl-SO (sub 4) geothermal fluid at near neutral pH and approximately 200 degrees C rather than a magmatic source. The magma conduit appears to have been invaded by remnants of the pre-eruptive hydrothermal system shortly after the end of dome emplacement. This blocked the direct degassing path and the combination of the large catchment area ( approximately 5km (super 2) ), and high precipitation led to rapid transition from a small, hot acid lake to a large lake with near-ambient T and pH. This is in contrast with peak-activity lakes with more sustained volcanic gas influx such as Kawah Ijen (indonesia) and, Poas and Rincon del Vega (Costa Rica).

Specifically, we constructed a dual-permeability model using TOUGH2 to represent both the matrix and fracture continua of the upper basalt flow at the Box Canyon Site. A consistent set of hydrogeological parameters was obtained by calibrating the model to infiltration front arrival times in the fracture continuum as inferred from Br (super -) samples collected from fracture-borehole intersections observed during the infiltrating tests. These parameters included the permeability of the fracture and matrix continua, the interfacial area between the fracture and matrix continua, and the porosity of the fracture continuum. To calibrate the model, we multiplied the fracture-matrix interfacial area by a factor between 0.1 and 0.01 to reduce imbibition of water from the fracture continuum into the matrix continuum during the infiltration tests. Furthermore, the porosity of the fracture continuum, as calculated using the fracture aperture inferred from pneumatic-test permeabilities, was increased by a factor of 50 yielding porosity values for the upper basalt flow in the range of 0.01 to 0.02. The fracture-continuum porosity was a highly sensitive parameter controlling the arrival times of the simulated infiltration fronts. Porosity values are consistent with those determined during the Large-Scale Aquifer Pumping and Infiltration Test at the Idaho National Engineering and Environmental Laboratory.

Nitrogenase activity was approximately 10 and 2.5 times higher in mature crusts than in poorly developed crusts at the Colorado Plateau site and Chihuahuan Desert site, respectively. Analysis of nifH sequences by clone sequencing and the terminal restriction fragment length polymorphism technique indicated that the crust diazotrophic community was 80 to 90% heterocystous cyanobacteria most closely related to Nostoc spp. and that the composition of N sub(2)- fixing species did not vary significantly between the poorly developed and mature crusts at either site. In contrast, the abundance of nifH sequences was approximately 7.5 times greater (per microgram of total DNA) in mature crusts than in poorly developed crusts at a given site as measured by quantitative PCR. 16S rRNA gene clone sequencing and microscopic analysis of the cyanobacterial community within both crust types demonstrated a transition from a Microcoleus vaginatus-dominated, poorly developed crust to mature crusts harboring a greater percentage of Nostoc and Scytonema spp. We hypothesize that ecological factors, such as soil instability and water stress, may constrain the growth of N sub(2)-fixing microorganisms at our study sites and that the transition to a mature, nitrogen-producing crust initially requires bioengineering of the surface microenvironment by Microcoleus vaginatus.

B. thuringiensis and B. cereus isolates were from diverse sources and locations, including soil, clinical isolates and food products causing diarrheal and emetic outbreaks, and type strains from the American Type Culture Collection, and over 200 B. thuringiensis isolates representing 36 serovars or subspecies were from the U.S. Department of Agriculture collection. Twenty-four diverse B. anthracis isolates were also included. Phylogenetic analysis of AFLP data revealed extensive diversity within B. thuringiensis and B. cereus compared to the monomorphic nature of B. anthracis. All of the B. anthracis strains were more closely related to each other than to any other Bacillus isolate, while B. cereus and B. thuringiensis strains populated the entire tree. ten distinct branches were defined, with many branches containing both B. cereus and B. thuringiensis isolates. A single branch contained all the B. anthracis isolates plus an unusual B. thuringiensis isolate that is pathogenic in mice. In contrast, B. thuringiensis subsp. kurstaki (ATCC 33679) and other isolates used to prepare insecticides mapped distal to the B. anthracis isolates. The interspersion of B. cereus and B. thuringiensis isolates within the phylogenetic tree suggests that phenotypic traits used to distinguish between these two species do not reflect the genomic content of the different isolates and that horizontal gene transfer plays an important role in establishing the phenotype of each of these microbes.

To establish the molecular epidemiology we sequenced the env V3 and gag p17 regions of the HIV genome and compared them with reference sequences using phylogenetic analyses. As expected, the vast majority (n = 88; 91%) were intravenous drug users (IDUs) from the Riga region. Also, the majority of the investigated individuals (n = 93; 96%) were found to carry a subtype A1 virus that may have entered the Latvian IDU population several times. In addition, one IDU was infected with CRF03_AB and three other individuals, who had been infected through sexual contacts, carried subtype B virus. Thus, subtype A1 dominates the Latvian epidemic and is strongly associated with the IDU risk group. Although some spread of subtype A1 has occurred in the heterosexual group, subtype B dominates among homosexually and heterosexually infected individuals.

AN - 71806300; 15055929 AB - Material Disposal Area G (Area G) at the Los Alamos National Laboratory is a low-level radioactive waste disposal facility. The noticeably high activity of pocket gophers on closed waste burial sites of various types at Area G resulted in the need to understand possible interactions between gophers and radioactive waste. Fossorial animals can influence the fate of contaminants by directly burrowing into waste trenches, pushing contaminated soil to the surface, or through indirect mechanisms such as consumption of contaminant-laden vegetation or the ingestion of soil. In our study, pocket gophers, mound soil, surface soil, and vegetation were collected at Area G and at offsite reference locations. The samples were analyzed for 241Am, 238Pu, 239Pu, 3H, and total U. It did not appear that gophers were responsible for any upward transport of radionuclides. Concentrations of 241Am, 238Pu, 239Pu, and 3H in some gophers, soil, and vegetation were higher than at reference sites; however, only 3H in gopher carcasses at only one of five sites within Area G was higher than a conservative ecological screening level.

AN - 67302163; 15880916 AB - The CEM2k and LAQGSM codes have been recently developed at Los Alamos National Laboratory to simulate nuclear reactions for a number of applications. We have benchmarked our codes against most available data measured at incident particle energies from 10 MeV to 800 GeV and have compared our results with predictions of other current models used by the nuclear community. Here, we present a brief description of our codes and show some illustrative results that testify that CEM2k and LAQGSM can be used as reliable event generators for space-radiation-shielding, cosmic-ray (CR) propagation, and other astrophysical applications. Finally, we show an example of combining of our calculated cross-sections with experimental data from our LANL T-16 compilation to produce evaluated files. Such evaluated files were successfully used in the model of particle propagation in the Galaxy GALPROP to better constrain the size of the CR halo.

AN - 66860086; 15353733 AB - Analysis of accident dosemeters usually involves the use of laboratory-based counting equipment. Gamma spectrometers are used for indium, copper and gold, and alpha-beta detectors for sulphur. This equipment is usually not easily transported due to the shielding required and the weight and delicacy of the counters. For intercomparison studies that require reading the dosemeters on site, a transportable system is required unless the site operating the study can count samples for all the participants. In the case of an actual accident these systems would have a difficulty in counting a large number of accident dosemeters. In an accident, personnel are usually subdivided according to their level of exposure. Those exposed to higher doses are treated immediately. An alternate system should be made available to handle the dosemeters worn by those personnel are likely to receive lower doses. Improvements in portable operational equipment for gamma and beta monitoring allow their use as spectrometers. Such a system was used for the SILENE intercomparison conducted at IRSN Valduc on 12 June and 19, 2002, and the preliminary results compared well with the other participants.

AN - 66858256; 15353697 AB - In the application of criticality accident dosemeters the cross sections and fluence-to-dose conversion factors have to be computed. The cross section and fluence-to-dose conversion factor for the thermal and epi-thermal contributions to neutron dose are well documented; for higher energy regions (>100 keV) these depend on the spectrum assumed. Fluence is determined using threshold detectors. The cross sections require the folding of an expected spectrum with the reaction cross sections. The fluence-to-dose conversion factors also require a similar computation. The true and effective thresholds are used to include the information on the expected spectrum. The spectra can either be taken from compendia or measured at the facility at which the exposures are to be expected. The cross sections can be taken from data computations or analytic representations and the fluence-to-dose conversion factors are determined by various standards making bodies. The problem remaining is the method of computation. The purpose of this paper is to compare two methods for computing these factors: analytic and Monte Carlo.

AN - 66854058; 15353648 AB - The design of a portable high-energy (20-800 MeV) neutron spectrometer based on CsI or BaF2 is described. The particle discrimination properties of these scintillators allow the light-ion spallation products (p, d, t and alpha) from neutron interactions to be identified uniquely. One or more of the resulting pulse-height spectra can be unfolded to reveal the incident neutron spectrum. Dosimetric quantities can then be calculated based on the unfolded spectrum. Due to the high stopping power of these scintillators, modest-sized crystals are suitable for this application. Combined with advances in electronics, a lightweight instrument capable of on-line particle discrimination with a real-time display of neutron-induced count rate is feasible. Preliminary experimental data are presented, and the importance of validating MCNPX-generated response functions is discussed. A brief discussion on future work follows.

Accurate numerical simulation requires fine spatial and temporal discretization to resolve the smallest scales of heterogeneity, in addition to coupling large numbers of chemical components participating in geochemical and microbiological reactions. Standard approaches based upon finite difference or finite element discretization of the governing set of advection-dispersion-reaction equations can lead to computational difficulties for large problems. To overcome these difficulties, several streamtube-based models have been presented in the literature. These models neglect transverse dispersion, and hence reactive transport occurs along independent one-dimensional streamtubes. Therefore, streamtube models are well-suited for applications where the objective is to calculate solute flux breakthrough across a control plane. We develop a reactive streamtube model by modification of the Finite Element Heat and Mass transfer code (FEHM), an existing flow and transport code. FEHM can simulate unsaturated zone conditions, heat flow, and multicomponent reactive transport, and has been used extensively by the Yucca Mountain Project. Because the same underlying numerical algorithms are used in both the FEHM and streamtube models, direct comparison of their relative performance is possible.

We track plume-related hot spot motion while calculating associated synthetic hot spot tracks, allowing us to estimate plume migration rates relative to plate motion rates. Plate-like surface motion is achieved explicitly by specifying both the plate geometry and rigidity; however, plate velocities evolve dynamically in response to the buoyancy distribution within the convecting system, including buoyancy within the plate itself. We find that convection is characterized by downwelling sheets and varying numbers of 3-D upwelling structures when the lower mantle to upper mantle viscosity ratio is varied from 9 to 90. As the lower mantle viscosity is increased relative to the upper mantle viscosity, the upwellings in the calculations evolve into vigorous (active) plumes characterized by long, narrow, thermal conduits with broad, disk-like heads. The total number, shape, and persistence of the plumes are affected by the specified viscosity stratification in the calculations. Our findings indicate that hot spots associated with mantle plumes drift by smaller distances in comparable amounts of time when the lower mantle viscosity is increased relative to the upper mantle viscosity. In cases with a high lower mantle to upper mantle viscosity ratio, the depth of the flow aligned with plate motion is diminished and the plate-scale return flow is integrated into a deep, unorganized, sluggish layer. As a result, plume conduit morphology in the lower mantle of such calculations is less influenced by plate motion than in calculations with a small difference between upper mantle and lower mantle viscosity. For lower mantle viscosities 30 times and 90 times greater than the upper mantle viscosity, the lower mantle velocity field is dominated locally by active plumes anchored in the lower thermal boundary layer of the convecting system and plume migration rates are typically only about 10% of the overriding plate velocity. In such cases, we also find that plume-related hot spots persist for periods that we estimate to be between 0.55 and 1.1 plume-transit times.

Subsidence features, gas vents, ash, condensates, and red oxidized shales are surface manifestations of the fire. The likely success of conventional fire-containment methodologies in South Canyon is questionable, although drilling data may eventually suggest a useful control procedure. Drill casings in voids in the D coal seam on the western slope trail are useful for collecting gas samples, monitoring the temperature of subsurface burning, and measuring the concentration of gases such as carbon monoxide and carbon dioxide in the field. Coal fire gas and mineral condensates may contribute to the destruction of floral and faunal habitats and be responsible for a variety of human diseases; hence, the study of coal gas and its condensation products may prove useful in understanding environmental pollution created by coal mine fires. The 2002 Coal Seam Fire, which burned over 12,000 acres and destroyed numerous buildings in and around Glenwood Springs, exemplifies the potential danger an underground coal fire poses for igniting a surface fire.

The phase 2 tracer test was conducted within an instrumented 10 m by 10 m by 7 m in situ block of vitric tuff. A complex tracer solution containing both reactive and nonreactive tracers was pumped into the block during a period of 27 months. Throughout the test, thousands of unsaturated zone pore water samples were collected on sorptive pads attached to inverting membranes and then analyzed for tracer concentration. Partway through the experiment, three new boreholes were drilled into the block, and two intercepted the tracer plume. The rock core was removed for pore water extraction and analysis, and the boreholes were then instrumented with inverting membranes and sorptive pads. The initial set of pore water-soaked pads was removed from the boreholes a week after they were emplaced, and the pore water was extracted and analyzed. This paper compares the tracer concentration data from the rock cores and the pads to evaluate the effectiveness of the inverting membrane collection technique for a variety of tracers. While the sorptive pads sample only dissolved tracers, rock cores contain both dissolved and sorbed tracer. For nonreactive tracers, such as halides (bromide and iodide) and fluorinated benzoic acids (FBAs), this distinction is immaterial, and the rock and pad data agree quantitatively for the halide tracers, and qualitatively for the FBAs. For reactive tracers, such as lithium, the dissolved tracer concentrations can be estimated from rock analyses by dividing by the tracer's retardation factor; when this correction is applied, the rock and pad lithium data are also in reasonable agreement.

Volcanic emission rates of Cl, F, Pb, As, Hg, Sb and Se were determined at White Island, New Zealand, using chemical traps containing 4 N NaOH solutions. Traps were located in both the fumarole area and at the crater rim where they would be exposed to the main volcanic gas plume. The chemical ratios relative to sulphur of the fumarole samples were distinctly different from the ratios of samples exposed to the gas plume. The trace metal fluxes were determined using the species to S ratios in the solutions combined with independently determined SO (sub 2) emission rates measured by correlation spectrometer. At White Island, chemical traps yielded flux values of Cl=84, F=0.8 Mg.d (super -1) (tonnes per day) and Pb=28, As=17, Hg=0.84, Sb=1.8 and Se=1.3 kg.d (super -1) .

The fracture and matrix continua of the basalt were represented using a dual-permeability approach. Six perched-water hydrographs, measured during the infiltration test, were used for calibration with iTOUGH2 to estimate six parameters that controlled unsaturated flow in the fractured basalt and the dense clay sedimentary interbed underlying the basalt flow. These parameters included the interfacial area between the basalt fracture and matrix continua, the basalt fracture continuum permeability, the basalt matrix continuum permeability, the interbed matrix continuum permeability, and the interbed van Genuchten capillary pressure parameters. The intent of the calibration was to obtain large-scale properties of the lithological units affecting the field-scale LPIT test. Finally, we tested the applicability of the dual-permeability conceptual model for representing transient variably saturated flow in fractured basalt. Parameters obtained from the calibration were within the range of hydrogeological parameters measured from cores obtained in the field, substantiating the physical relevance of the calibration effort.

AN - 50067127; 2010-028185 AB - The northeast-trending Embudo fault has a significant component of left-lateral slip and acts as a transfer fault in relaying extensional strain between the San Luis and Espanola Basins. In the northern Espanola Basin, the Embudo fault system links with the La Mesita and Dixon-Velarde faults of the northern Velarde graben, a 6-10 km-wide intra-rift graben. There is no evidence that a single scissors fault connects the down-to-the-northwest Embudo fault with the major down-to-the-east faults that bound the western side of the deepest parts of the central Espanola Basin (e.g., the Pajarito fault system). Rather, late Cenozoic slip associated with the Embudo fault appears to be partitioned amongst several major faults in the Velarde graben. In the southern Velarde graben, a lateral transfer of slip likely occurs between these faults and a major down-to-the-east fault called the Santa Clara fault. This transfer zone likely corresponds to an important fault segment boundary and is marked by transverse folds that may follow a transverse basement structure. Stratigraphic and seismic data indicate that substantial throw occurred along at least two major Velarde graben faults prior to the deposition of upper Miocene strata. This interpretation is consistent with a steepening of seismic reflectors with depth along the eastern margin of the Velarde graben. We speculate that the gravity high extending northwestward from the Picuris Mountains may correspond to a structural high related to the early development of the rift transfer zone between the Espanola and San Luis Basins. Subsequently, fault propagation and linkage may have formed a through-going Embudo fault system.

Constant K sub(d) models for describing radionuclide retardation are not valid under these conditions because of strong competition for sorption sites by abundant Na super(+) 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 super(-1), and fitted cation exchange capacity of 0.05 mol kg super(-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.

Moreover, in cases where a biological agent release has been identified, forensic analysis demands detailed genetic signature data for accurate strain identification and attribution. To date, nucleic acid sequences have provided the most robust and phylogentically illuminating signature information. Nucleic acid signature sequences are not often linked to genomic or extrachromosomal determinants of virulence, a link that would further facilitate discrimination between pathogens and closely related species. Inextricably coupling genetic determinants of virulence with highly informative nucleic acid signatures would provide a robust means of identifying human, livestock, and agricultural pathogens. By means of example, we present here an overview of two general applications of microarray-based methods for: (1) the identification of candidate virulence factors; and (2) the analysis of genetic polymorphisms that are coupled to Bacillus anthracis virulence factors using an accurate, low cost solid-phase mini-sequencing assay. We show that microarray-based analysis of gene expression can identify potential virulence associated genes for use as candidate signature targets, and, further, that microarray-based single nucleotide polymorphism assays provide a robust platform for the detection and identification of signature sequences in a manner independent of the genetic background in which the signature is embedded. We discuss the strategy as a general approach or pipeline for the discovery of virulence-linked nucleic acid signatures for biothreat agents.

Electrical resistivity, magnetic susceptibility, specific heat and field-dependent resistance measurements show that this is a bulk, type II superconductor below the superconducting transition T ( approximately 4 K), and survives in a magnetic field up to 3.5 T. The results indicate that Si and Ge, which also form in the diamond structure, may show superconductivity under appropriate conditions.

Our objective was to evaluate the development of lateral subsurface flow and soil saturation at a semiarid ponderosa pine forest in New Mexico with respect to the conceptual model of saturation building above the soil-bedrock contact. At this site, we have long-term observations of the water budget components, including lateral flow. A 1.5 m deep by 7 m long trench was constructed to observe lateral subsurface flow and development of saturation directly. Our observations are based on flow resulting from a melting snowdrift. The edge of the drift was about 7 m upslope from the trench. Lateral subsurface flow only occurred from root macropores in the Bt soil horizon. Saturation developed and grew outward from flowing root macropores, rather than growing upward from the soil-bedrock interface. This macropore-centred saturation resulted in a highly heterogeneous distribution of water content until enough macropores began flowing and individual macropore saturated zones grew large enough to coalesce and saturate large volumes of the soil. Our observations are based on one snowmelt event and a relatively short hillslope flow path, and thus do not represent a full range of hydrologic conditions. Nevertheless, the observed behaviour did not conform to the traditional model of soil-bedrock control of saturation and lateral flow.

The author, who heads the (Security) Vulnerability Assessment Team at Los Alamos National Laboratory, therefore argues that techniques used to optimize security might be useful for optimizing safety. Optimizing Security: There are three main ways to attempt to improve security; security surveys, risk assessment (or 'design basis threat'), and vulnerability assessments. The latter is usually the most effective. Safety Analogs: Vulnerability assessment techniques used to improve security can be applied to safety analysis; even though safety is not ordinarily viewed as having malicious adversaries (other than hazards involving deliberate sabotage). Thinking like a malicious adversary can nevertheless have benefits in identifying safety vulnerabilities. Suggestions: The attributes of an effective safety vulnerability assessment are discussed, and recommendations are offered for how such an adversarial assessment might work. Conclusion: A safety vulnerability assessment can potentially provide new insights, a fresh and vivid perspective on safety hazards, and increased safety awareness.

The approach is first validated for a two-dimensional layered flow. The velocity profiles and the relative permeability coefficients are compared with the analytic results. We then apply this method to studying fingering in a two- dimensional channel where one fluid is displaced by another. The effects of viscosity ratio, capillary number, and wettability are investigated. The simulation results show that with the increase of the viscosity ratio or capillary number, both the finger width and the slip distance of the contact lines decrease, while the finger length increases. With the decrease of the wettability of the displacing fluid, the finger length and its change rate with time increase while the slip distance of the contact lines and its change rate with time decrease, and the minimum capillary number to form a stable finger decreases. Hence the finger growth is enhanced when the displacing fluid is nonwetting to the wall and otherwise suppressed. An indented part near the beginning of the fingers is clearly observed when a wetting fluid is displacing a nonwetting one. The finger width, however remains nearly unchanged when the wettability of the fluids changes.

The assay uses microspheres of two sizes, each coupled to an influenza type A- or type B-specific monoclonal antibody (MAb), to capture influenza viruses in the sample. A cocktail of fluorescently labeled, influenza-specific polyclonal antibodies then binds the captured viruses. The sandwich complexes are measured using a multiparameter flow cytometer. The assay can distinguish between influenza types A and B in a single reaction with good reproducibility and high sensitivity. Detection sensitivity is much higher than that of commercially available influenza diagnosis quick kits: the FLU OIA (Thermo Biostar) kit and the Directigen Flu A+B kit (Becton Dickinson). The multiplexing capabilities of the current assay, which are not possible with enzyme-linked immunosorbent assay (ELISA) and the commercially available kits, reduce sample handling and consume fewer costly reagents. This assay represents a more efficient and sensitive method of characterizing influenza types. With inclusion of influenza subtype-specific antibodies as capture antibodies, this microsphere-based immunoassay can be expanded to differentiate among influenza types and subtypes in a single reaction to improve world-wide influenza surveillance.

A superconducting quantum interference device (SQUID) sensor coupled to a gradiometer pickup coil was used to measure the NMR and MEG signals. super(1)H NMR spectra with typical Larmor frequencies from 100-1000 Hz acquired simultaneously with the evoked MEG response from a stimulus to the median nerve are reported. The single SQUID gradiometer was placed approximately over the somatosensory cortex of a human subject to noninvasively record the signals. These measurements demonstrate, for the first time, the feasibility of simultaneous MRI and MEG. NMR in the microtesla regime provides narrow linewidths and the potential for high spatial resolution imaging, while SQUID sensors enable direct measurement of neuronal activity with high temporal resolution via MEG.

Genes of tryptophan biosynthesis are frequently organized as whole-pathway operons, an attribute that is expected to facilitate multi-gene transfer in a single step. We have asked whether events of lateral gene transfer are sufficient to have obscured our ability to track the vertical genealogy that underpins tryptophan biosynthesis. Results: In 47 complete-genome Bacteria, the genes encoding the seven catalytic domains that participate in primary tryptophan biosynthesis were distinguished from any paralogs or xenologs engaged in other specialized functions. A reliable list of orthologs with carefully ascertained functional roles has thus been assembled and should be valuable as an annotation resource. The protein domains associated with primary tryptophan biosynthesis were then concatenated, yielding single amino-acid sequence strings that represent the entire tryptophan pathway. Lateral gene transfer of several whole-pathway trp operons was demonstrated by use of phylogenetic analysis. Lateral gene transfer of partial-pathway trp operons was also shown, with newly recruited genes functioning either in primary biosynthesis (rarely) or specialized metabolism (more frequently). Conclusions: (i) Concatenated tryptophan protein trees are congruent with 16S rRNA subtrees provided that the genomes represented are of sufficiently close phylogenetic spacing. There are currently seven tryptophan congruency groups in the Bacteria. Recognition of a succession of others can be expected in the near future, but ultimately these should coalesce to a single grouping that parallels the 16S rRNA tree (except for cases of lateral gene transfer). (ii) The vertical trace of evolution for tryptophan biosynthesis can be deduced. The daunting complexities engendered by paralogy, xenology, and idiosyncrasies of nomenclature at this point in time have necessitated an expert-assisted manual effort to achieve a correct analysis. Once recognized and sorted out, paralogy and xenology can be viewed as features that enrich evolutionary histories.

Both uranium corrosion products on the surface, and subsurface uranium originating from the dissolution of surface corrosion products followed by reprecipitation or sorption, were examined. A four-step sequential extraction method was used to classify uranium solubility at each site. Results show that distribution coefficient for uranium is highly variable, but can be correlated with the clay content (r = 0.55) and soil pH (r = 0.73) of the soil horizon considered. Surface corrosion products and near-surface uranium easily dissolve in a weak acid solution (25% acetic acid for two hours), suggesting a uranyl hydroxide form. As uranium migrates beyond several centimeters in depth, it forms insoluble aggregates with silicate minerals and requires strong acids to leach it. The formation of uranium-silicate mineral aggregates appears to be the limiting factor in vertical vadose zone transport of DU at the site investigated.

This study presents a detailed analysis of the distribution of one contaminant along an ephemeral stream after 55 years of sediment transport, deposition, and exchange by flash floods. Wastewater containing plutonium was discharged into the Pueblo Canyon watershed from 1945 until 1964, and plutonium concentrations in fluvial deposits vary over five orders of magnitude. These variations can be attributed to three primary factors: time since contaminant releases, particle-size sorting, and mixing of sediment from different sources. The highest concentrations occur in fine-grained sediment deposits near the source that date to the period of effluent releases, and concentrations are lower in younger deposits, in coarser-grained deposits, and in deposits farther downstream. The spatial distribution of plutonium is strongly affected by longitudinal variations in the size of sediment deposits of different age. A major aggradation-degradation cycle in the lower canyon overlapped with the period of active effluent releases, and a significant portion of the total plutonium inventory is contained within large coarse-grained deposits below fill terraces that post-date 1945. The spatial pattern of contamination is thus determined by the specific geomorphic history of the watershed, in addition to processes of mixing and sorting during transport that occur in all fluvial systems.

On the other hand, anthropogenic emissions in some areas of the world have been reduced very considerably during the last two decades (this is especially true for Europe). This fact shows clearly that the importance of biogenic emissions is increasing, because the ratio of biogenic emissions to total emissions, where the total emissions are equal to the sum of biogenic and anthropogenic emissions, is increasing. It is, therefore, necessary to study carefully the sensitivity of pollution levels to variations of biogenic emissions. A long series of runs with different scenarios, in which both biogenic and anthropogenic emissions were varied, has been performed. The influence of both types of emission on AOT40 values, which have damaging effects on corns when certain critical values are exceeded, was studied. The results show clearly that biogenic emissions must also be taken into account when control strategies are developed for reducing anthropogenic emissions in order either to reduce some high pollution levels to prescribed critical levels or to keep them below the critical levels.

AN - 51881758; 2004-018142 AB - Yucca Mountain, Nevada, has been approved by the U.S. Congress as the site of the first high-level radioactive waste repository in the U.S., paving the way for the Department of Energy to submit a license application to the Nuclear Regulatory Commission. The U.S. concept of a radioactive waste repository involves both engineered (man-made) barriers and geologic barriers to minimize the longterm migration of waste from the repository. The minerals at Yucca Mountain are an integral part of the geologic barrier to the migration of radionuclides, and understanding the distribution of reactive and potentially sorptive minerals is crucial to modeling the long-term performance of the repository. We have determined the three-dimensional distribution of minerals at Yucca Mountain by analyzing a number of drill cores using quantitative X-ray diffraction methods. Clinoptilolite and mordenite are locally abundant in the rhyolitic tuffs in both the unsaturated and saturated zones. They formed by the alteration of glassy rhyolitic tuffs, and their occurrence is stratified, often following the distribution of nonwelded, initially vitric tuffs near and below the water table. Because of their large cation-exchange capacities, these minerals have traditionally been considered to be important in retardation of the migration of cationic radionuclides such as (super 137) Cs and (super 90) Sr. However, analysis of radionuclides that may be contained at Yucca Mountain reveals that, for the most part, the radioactive species of concern are not those that would be readily sorbed by natural zeolites. Although clinoptilolite and mordenite are highly selective for Cs and Sr, the half-lives of these radionuclides ( approximately 30 years) are sufficiently short that the man-made containment at any radioactive waste repository is expected to outlive these radionuclides. The most important radionuclides are thus anionic species and long-lived actinides that often form large, complex aqueous species, both of which are not strongly sorbed by cation exchangers such as zeolites. However, zeolites play an important role in a repository at Yucca Mountain for several other reasons. Emplacement of radioactive waste will change the temperature and PH (sub 2) O conditions in large volumes of rock, and zeolites will be important sources and sinks of water and thermal energy during heating and cooling in the vadose zone. In addition, dehydration/hydration reactions are accompanied by volumetric changes that can affect macroscopic rock properties. Longer-term reactions, e.g., of clinoptilolite to analcime, would give rise to larger volume reductions and production of water and silica. These studies show that the importance of zeolites extends far beyond cation exchange by zeolites to phenomena affecting the entire thermohydrologic system.

Equilibrium partition constants (Li (super +) K (sub d) S) were measured using batch studies incorporating a wide range of Li (super +) concentrations and two different grain-size fractions of alluvium samples from multiple depth intervals in two wells. Cation exchange capacity, surface area, bulk mineralogy from quantitative X-ray powder diffraction, and trace Mn- and Fe-oxyhydroxide mineralogy from extractive studies were evaluated as predictors for linearized Li (super +) K (sub d) values (K (sub lin) ) in the alluvium. Many of the predictor variables are correlated with each other and this was considered in the analysis. Linearized K (sub d) values were consistently higher for fine particle-size fractions than for coarse fractions. Single and multivariate linear regression analyses indicated that the clinoptilolite + smectite content, taken together as a combined variable, was the best predictor for Li (super +) sorption in the alluvium, although clinoptilolite content was clearly a better predictor when the two variables were considered separately in simple linear regressions. Even so, Li (super +) K (sub lin) predictions based on clinoptilolite and smectite abundance were accurate only to within about + or -100%. This uncertainty suggests that there is either a high inherent variability in Li (super +) K (sub lin) values or that additional alluvium characteristics not measured or evaluated here may play an important role in simple Li (super +) cation exchange in the alluvium.

A custom interfacing scheme has been used to assemble individual chips into the functional system. This system has been used to perform cell pre-concentration from a complex sample matrix allowing for carrying out assays on rare cell targets appearing in low concentrations in the analyzed sample. We demonstrate that 2 ml of the sample can be processed in a cell capture modular system with cell capture efficiency of 53 and 37% for PBS- and blood-based samples, respectively. We also show that these capture rates are strongly dependent on the effectiveness of pre-capture mixing between the cell containing sample and bead-antibody complexes.

By inserting diverse antibody binding loops into four of the exposed loops at one end of green fluorescent protein (GFP), we have mimicked the natural antibody binding footprint to create robust binding ligands that combine the advantages of antibodies (high affinity and specificity) with those of GFP (intrinsic fluorescence, high stability, expression and solubility). These 'fluorobodies' have been used effectively in enzyme-linked immunosorbent assays (ELISAs), flow cytometry, immuno-fluorescence, arrays and gel shift assays, and show affinities as high as antibodies. Furthermore, the intrinsic fluorescence of fluorobodies correlates with binding activity, allowing the rapid determination of functionality, concentration and affinity. These properties render them especially suitable for the high-throughput genomic scale selections required in proteomics, as well as in diagnostics, target validation and drug development.

In this study, the immunocompetence of Western Bluebirds (Sialia mexicana) and Ash-throated Flycatchers (Myiarchus cinerascens) was studied on a landscape-soil contaminant gradient at Los Alamos National Laboratory (LANL) in New Mexico during 1997-1999. A variety of contaminants (heavy metals, chemicals, insecticides, polychlorinated biphenyls, and radioactive isotopes) range across different spatial scales and concentrations on LANL land. The two species have similar life-history traits, except that the Ash-throated Flycatcher has a faster rate of development and fledges 4-5 days earlier than the bluebird. The number of active nest boxes increased from 1997 to 1998 and 1999 for the Western Bluebird, but not for the Ash-throated Flycatcher. Survival of nestling flycatchers was lower in areas within 60 m of a potential contaminant release site, with a higher survivorship function associated with boxes farther away. The two species did not differ in their response to antigens, and there was no difference between locations for immunocompetence for either species. Flycatcher nestlings had a higher average cell-mediated response than bluebird nestlings, as predicted by the faster rate of development of the flycatchers. Phytohemagglutinin response varied between locations for both species. The cell-mediated effects were dynamic in that, in general, the same locations showed similar patterns for each year. Hematocrits steadily increased with age for both species and varied between locations for the bluebird, but not the flycatcher.

AN - 71468406; 14674564 AB - Post-treatment of leachate from soil-washing remedial actions may be necessary depending on the amounts of dissolved contaminants present. Uptake of arsenic species by surfactant-modified zeolite (SMZ) from a synthetic soil leachate (pH of approximately 12 [NaOH]) was measured as a test of SMZ as a post-treatment sorbent. Batch sorption isotherms were prepared using leachate to SMZ ratios from 40:1 to 4:1, and temperatures of 25 and 15 degrees C. Equilibrium levels of dissolved and total solution arsenic were similar. At each temperature, sorption appeared to reach a plateau or maximum, then decreased at the highest solution concentration, corresponding to the lowest amount of zeolite added (2.5 g). A maximum sorption value of 72.0 mmol of arsenic per kg of SMZ (5400 mg/kg) was observed at 25 degrees C, and 42.1 mmol/kg (3150 mg/kg) at 15 degrees C. Total arsenic recoveries varied from 74 to 125%. Surfactant-modified zeolite removed up to 97% of dissolved organic carbon and decolorized the leachate solutions. Excluding the points for the highest arsenic to SMZ ratio, the sorption isotherms were well described by the linearized form of the Langmuir equation, with coefficients of determination greater than 0.90 at both temperatures. Sorption of arsenic by SMZ is attributed to anion exchange with counterions on the surfactant head groups, and/or partitioning of organic carbon-complexed arsenic into the surfactant bilayer.

AN - 71290445; 14571993 AB - Alarming continuous air monitors (CAMs) are a critical component for worker protection in facilities that handle large amounts of hazardous materials. In nuclear facilities, continuous air monitors alarm when levels of airborne radioactive materials exceed alarm thresholds, thus prompting workers to exit the room to reduce inhalation exposures. To maintain a high level of worker protection, continuous air monitors are required to detect radioactive aerosol clouds quickly and with good sensitivity. This requires that there are sufficient numbers of continuous air monitors in a room and that they are well positioned. Yet there are no published methodologies to quantitatively determine the optimal number and placement of continuous air monitors in a room. The goal of this study was to develop and test an approach to quantitatively determine optimal number and placement of continuous air monitors in a room. The method we have developed uses tracer aerosol releases (to simulate accidental releases) and the measurement of the temporal and spatial aspects of the dispersion of the tracer aerosol through the room. The aerosol dispersion data is then analyzed to optimize continuous air monitor utilization based on simulated worker exposure. This method was tested in a room within a Department of Energy operated plutonium facility at the Savannah River Site in South Carolina, U.S. Results from this study show that the value of quantitative airflow and aerosol dispersion studies is significant and that worker protection can be significantly improved while balancing the costs associated with CAM programs.

The reservoir has been accumulating in subsoil zones of arid regions throughout the Holocene. Consideration of the subsoil reservoir raises estimates of vadose-zone nitrogen inventories by 14 to 71% for warm deserts and arid shrublands worldwide and by 3 to 16% globally. Subsoil nitrate accumulation indicates long-term leaching from desert soils, impelling further evaluation of nutrient dynamics in xeric ecosystems.

In the thick unsaturated zone ( approximately 500-600 m), rhyolitic compositions predominate, with latitic compositions restricted to a zone approximately 50 m thick and approximately 150 m above the proposed repository horizon. Underlying strata down through the repository horizon and extending below the water table are relatively uniform in rhyolitic composition, with formation of thick zeolitized horizons from initially vitric rhyolites near the water table. The latitic zone has a distinct geochemical character (lower Si/Al and Rb/Sr ratios; higher Fe, Mg, Ti, Zr, Ba; higher light lanthanide content and little or no Eu anomaly) compared with the rhyolites. Clays (dominantly smectites) within the latitic horizon inherit most of this latitic geochemical character, whereas smectites in rhyolitic units inherit rhyolitic characteristics. These differences point to in situ clay formation, predominantly by dissolution of local latitic or rhyolitic glass. The clays can have either positive or negative Ce anomalies, in contrast to other alteration minerals that have no Ce anomalies (zeolites) or only negative Ce anomalies (calcites). The development of Ce anomalies provides information on whether alteration took place with or without influence from Ce-accumulating Mn-oxides. Although modeling, 36Cl data, and field experiments indicate that nonwelded portions of the latitic horizon play a significant role in accumulating and moderating recharge, the alteration in this zone is only partial, dominated by clays rather than zeolites, and bears evidence of dissolution leaching (e.g., Na depletion in clays relative to source glass). In contrast, the thick zeolitized horizons below the repository horizon represent complete and early alteration of glass within approximately 100 m of the present water table, with little geochemical exchange and minor clay formation. After essentially isochemical formation, this zeolitized zone has been variably overprinted by cation-exchange profiles. The record of zeolite and clay alteration indicates that the chemical composition of recharge waters is affected by glass dissolution in the vitric latitic horizons; these groundwaters are then modified by cation exchange in zeolitized horizons below the repository horizon.

Until that time, the U.S. had studied a variety of sites and areas to a limited extent, including those in bedded salt, salt domes, crystalline rocks, volcanic tuff and basalt. Yucca Mountain is now perhaps the most thoroughly studied site on Earth. The key question that defined the site characterization program was whether Yucca Mountain would safely isolate spent nuclear fuel and high-level waste for the regulatory period of 10,000 years. Congress' decision to concentrate study at Yucca Mountain presented unique challenges because of its hydrogeologic setting in a deep unsaturated environment and its location in the tectonically active Basin and Range physiographic province. Specifically, the amount and timing of infiltration and flow in the unsaturated zone (UZ) and the location of flow pathways required investigation. Whether flow was steady or transient, what portion of flow occurs in fractures vs. the rock matrix, the relative proportion of flowing fractures, and the existence of fast pathways were some of the key hydrologic questions. Transport properties of the volcanic and alluvial media encountered along portions of the flow paths were also important. The flow regimes required consideration in the context of future climate predictions as well as present conditions. The future potential for volcanism and seismicity to disturb Yucca Mountain was also of high priority for investigation. The studies presented in this session cover the breadth of site characterization activities over 25 years. Some of the work has been published and some is presented here for the first time. Collectively, this body of work forms the basis for a conceptual understanding of the processes anticipated to occur at Yucca Mountain in the future and will provide the foundation for the U.S. Department of Energy's License Application.

However, in a rigorous licensing environment, skeptical peer reviewers have suggested that differences in the responses of nonsorbing tracers may be the result of diffusion into stagnant free water in fracture networks rather than true matrix diffusion. It is difficult to refute this possibility on the basis of nonsorbing tracer responses alone. Los Alamos National Laboratory has participated in three field tracer tests in fractured media in which we used a weakly-sorbing cation-exchanging tracer, lithium ion, in addition to nonsorbing tracers to demonstrate matrix diffusion. Our rationale was that if diffusion occurred only into free water in the fracture system, lithium would be minimally retarded because of the small rock surface area available for sorption. Also, any retardation resulting from sorption to fracture surfaces would be expressed primarily as an arrival time delay. However, if diffusion occurred into the matrix, where the rock surface area to water volume ratio is large, lithium ion would be significantly retarded relative to the nonsorbing tracers, and this retardation would be expressed primarily as an attenuation in peak concentration rather than a time delay. In all three field tests, the tracer responses were consistent with lithium ion sorbing in the matrix; in fact, the lithium responses could not be explained in any other way. Furthermore, it was possible to simultaneously quantify lithium sorption occurring in the matrix and onto fracture surfaces. In conclusion, the use of a weakly sorbing tracer in conjunction with multiple nonsorbing tracers helped verify that the diffusion deduced from nonsorbing tracer responses was truly occurring in the matrix and not just in stagnant free water in the fractured media.

Mortandad Canyon was selected as the location for the PRB because the flow of alluvial groundwater is constrained by the geology of the canyon, a large network of monitoring wells already exists along the canyon reach, and the hydrochemistry and contaminant history of the canyon is well-documented. The PRB incorporates a sequence of four reactive media layers to immobilize or destroy a suite of contaminants present in alluvial groundwater, including Sr-90, Pu-238, 239, 240, Am-241, perchlorate, and nitrate. The four sequential media cells consist of gravel-sized scoria, apatite, pecan shells and cottonseed with an admixture of gravel (biobarrier), and limestone. Design elements of the PRB are based on laboratory-scale treatability studies and on a field investigation of hydrologic, geochemical, and geotechnical parameters. The PRB was designed with the following criteria: 1-day residence time within the biobarrier, 10-year lifetime for the PRB, minimization of surface water infiltration and erosion, optimization of hydraulic capture, and minimization of excavated material requiring disposal. Each layer has been ported to allow sampling of water and reactive media, and monitor wells are located immediately adjacent to the up- and down-gradient edges of the barrier. Preliminary results indicate that both nitrate and perchlorate are being reduced by microbial activity in the biobarrier.

Solute (contaminant) exchange between ground and surface water reservoirs takes place in the aquifer near ephemeral channels during recharge events. To investigate the behavior of contaminant migration under transient hydrological conditions, we are conducting a KBr tracer test in a shallow alluvial aquifer in DP Canyon at Los Alamos National Laboratory. The DP Canyon system is made up of several reaches containing discrete alluvial aquifers and a head-cut spring where ground water "daylights" and re-enters the subsurface. Historical contaminants of concern that have accumulated in the aquifer since the 1950s include Sr-90, Cs-137, H3, and perchlorate. A tracer mass of 47 kg of KBr dissolved in 100 gallons of formation water was injected into a well screened over the saturated thickness of the aquifer (approximately 5 ft). Br is currently being monitored in situ with ion selective Temphion probes and from samples collected manually at systematic intervals. Cation samples, including Sr-90, have been collected and analyzed to determine the extent of ion exchange as the plume migrates through the aquifer. Our observations indicate that runoff from the Los Alamos town site provides linear recharge along an ephemeral channel during snowmelt and precipitation events. The response of the water table is immediate with measured heads greater near, and diminishing away from, the axis of the channel. During the receding limb of the hydrograph, water table gradients relax allowing ground water, solute, and contaminants to flow back into the channel. As a result, surface/ground water interaction episodically flushes the aquifer adjacent to the channel and transports solute both in surface and ground water. Preliminary tracer data corroborate this model. Data show that although the centroid of the bromide plume remains in the upper to mid-part of the reach, Br has traveled extensively in the aquifer proximal to the channel during and shortly after runoff events. Ground/surface water exchange in the hyporheic zone appears to facilitate tracer migration close to the channel, with diminishing effects in the aquifer away from the channel.

Because of this, they represent an excellent, non-destructive tool for investigating the effect of hydrothermal alteration on magnetic mineral assemblages. We used FORC diagrams to study core samples of Paleozoic sedimentary formations obtained from the VC-1 and VC-2B cores drilled in the 1.2 Myr Valles caldera in New Mexico. These formations are a logical starting point for studies of the effects of thermal gradients on magnetic minerals because previous work has shown that corresponding stratigraphic units in the two cores have experienced very different temperature regimes since development of the caldera. Various magnetic measurements and Mossbauer spectroscopy indicate that the only magnetic mineral present in the samples is hematite so that the main differences in the FORC diagrams can be attributed to changes in grain size distribution. Our initial results suggest that grain sizes increase with increasing temperature, with the largest changes occurring mainly around 240-250 degrees C. This may represent a threshold temperature for a grain-coarsening reaction such as Ostwald ripening. Once the effects of thermal alteration are better understood in the Valles caldera system, FORC diagrams can be used to look at the effects on magnetic minerals of other hydrothermal systems, such as the Salton Sea.

The Pajarito Fault (PF) forms the active western boundary of the rift near Los Alamos, NM, where it strikes north to northeast along the western margin of Los Alamos National Laboratory. Along strike, the PF is expressed at the surface as a large normal fault, a faulted monocline, and a distributed zone of deformation with significant down-east vertical displacement of the 1.2 Myr-old Tshirege Member of the Bandelier Tuff (Qbt). Stratigraphic and geochemical correlations of Qbt subunits allow us to estimate displacement on the PF, even where mass wasting extensively modifies the escarpment. Detailed field studies of 7 km of the 40-km-long PF show that the geometry of the fault varies appreciably along-strike. Maximum stratigraphic separation occurs south of the study area, where the PF is expressed at the surface as two down-east normal faults with >200 m of displacement on Qbt. Farther north, within the study area, the PF is a narrow (300-m-wide) faulted monocline with >120 m stratigraphic separation, a prominent graben at the base of the escarpment, and hanging wall bedding that dips toward the fault--consistent with the fault tip having broken the surface. Down-east displacement on the PF diminishes somewhat to the north, the zone of deformation broadens, and bedding dips along the monocline decrease. Down-east displacement in this sector is accommodated by monoclinal folding and small-offset distributed normal faulting, including crestal grabens, with approximately 35 m maximum displacement on any single mapped fault. The along-strike variation in fault-zone structure suggests that the fault tip of the PF lies below the surface in the northern part of our study area. The youngest dated surface ruptures along the PF (late Holocene), and recent small magnitude earthquakes occurred near the north end of our study area. Previous paleoseismic investigations indicate that different fault traces along the PF have ruptured at different times. This may be a function of the distributed nature of faulting associated with upward and lateral propagation of the PF. An improved understanding of the geometry of the PF will aid in assessing seismic hazards in this area.

Both fractures and deformation bands (0.1 to10 mm-wide tabular zones within which grain and pore size have been reduced by cataclasis) have been found at Los Alamos, NM, and Busted Butte, NV-locations at which an understanding of the hydrogeology of faulted ignimbrites is of great societal concern. We have investigated the distribution of these structures within variably welded and crystallized (devitrified and/or vapor-phase crystallized), ash-dominated ignimbrite units, and have begun to evaluate their impact on fluid flow. The distribution of faults and fractures in ignimbrite sequences is determined by degree of welding and crystallization of individual units. Welding (compaction and fusion of matrix glass and pumice) increases the mechanical strength of a rock by decreasing porosity and increasing grain-contact area and strength. Welding influences mode of failure: we have documented fractures in faults in welded ignimbrite units, whereas faults in glassy, nonwelded units contain only deformation bands. Postdepositional crystallization can decrease porosity and increase grain-contact area and strength in nonwelded units via occlusion of porosity and production of a fine-grained, crystalline rock. Crystallization appears to be secondary to welding in affecting rock strength, as both fractures and deformation bands are found in crystallized, nonwelded units. These relationships between fault-zone structure and protolith petrophysical properties provide a basis for predicting fault-zone character from rock type, which is useful for fluid flow and transport models. Fractures are considered to be vadose-zone fluid-flow conduits in welded ignimbrites. However, the effect of deformation bands on nonwelded ignimbrite permeability has not been previously considered, as the structures were not previously recognized. Widespread alteration and cementation of deformation bands record preferential vadose-zone fluid transport, suggesting that deformation bands enhance unsaturated fault-zone permeability via pore-size reduction. The magnitude of this increase and the density of deformation bands necessary to create significant flow pathways have not yet been determined.

Root mean squared errors for both hydraulic head and spring discharge calibration for the steady-state model were an improvement over two previous two-dimensional modeling efforts of the Redwall-Muav aquifer. Both of these previous models only included three major springs and not the 17 smaller springs on the South Rim. Subsequently, a transient model was created and calibrated to stresses to the aquifer applied from 1989 to 2002. The model incorporated accurate pumping rates for wells near the South Rim and the impacts of conservation measures and alternative water supplies. The community of Tusayan at the gateway to the South Rim implements rain and snow catchment which decreases volumes of water available to recharge the aquifer. Extensive water conservation and reuse practices further reduce the potential for recharge because of loss of reused water through evapotranspiration by consumptive uses. The transient model was used to gain insight into potential impacts to springs from current pumping rates, conservation practices, and alternative water supplies. The model predicts potentially significantly decreased spring discharges at some small springs from current groundwater use on the Coconino Plateau. These spring discharge decreases are greater with the use of some conservation measures and alternative water supplies. Three-dimensional particle tracking was used to delineate the capture zones of the 20 springs. The particle-tracking shows that capture zones of the low discharge springs are small and close to the South Rim; hence their ability to be easily influenced by pumping near the South Rim.

To investigate, experiments were conducted in a flexible cell hydrothermal apparatus at physical-chemical conditions of the shallow crust. A synthetic arkose (microcline + oligoclase + quartz + biotite) plus argillaceous shale were reacted with 5.5 molal NaCl brine. The system was held at 200 C and 200 bars for 32 days to approach steady state, then injected with CO (sub 2) and allowed to react for an additional 45 days. In a parallel experiment, the system was allowed to react for 77 days without injection of CO (sub 2) . Trace ions initially absent from NaCl brine appeared in solution at mM (K, Ca, and SiO (sub 2) ) to uM (Mg, Al, Fe and Mn) quantities, reflecting reaction of brine with rock. Without CO (sub 2) injection, the SiO (sub 2) concentration (2.4 mM) was stable below calculated quartz solubility (3.9 mM). Injection of CO (sub 2) resulted in decreased pH (1 unit) and increased SiO (sub 2) concentration to a level near calculated chalcedony solubility (5.4 mM). In the experimental system containing acidic brine and supercritical CO (sub 2) , SiO (sub 2) concentrations were doubled by dissolution of silicate minerals and apparent concomitant inhibition of the precipitation of quartz (and other silicates). Evaluation of the mixing of hot hydrothermal solutions with ambient seawater at mid-ocean ridge vents (Janecky and Seyfried, 1984) also noted silica super-saturation and inhibition of quartz precipitation. These phenomena were attributed to kinetics of silica polymerization and precipitation under acid pH conditions, assumptions consistent with recent experimental results (Icopini, et al., 2002). Return of silica super-saturated brine into a rock-dominated reaction system buffered to more neutral pH conditions may enhance precipitation of quartz, chalcedony, or amorphous silica as veins or cements, depending on the permeability structure of the host rock. Similarly, loss of CO (sub 2) or phase separation with decreasing pressure can substantially shift pH and result in massive vein or scale formation.

Laboratory and industrial uses of supercritical carbon dioxide have become extensive in recent years, and provide new information and concepts relevant to geologic systems. As a result, supercritical carbon dioxide phase reactive properties and complex mixtures that can coexist at relatively moderate temperatures/pressures are beginning to be appreciated in a broad range of geologic systems. Simulation of reaction processes involving solution, minerals and a separate carbon dioxide phase requires consideration of geochemistry that has not been widely captured modeling code systems. Two specific aspects necessary to simulate this system have been developed in this research: multi-phase composition changes, and solution solute precipitation reactions. Both aspects were developed using existing simulation code systems. Initial systems investigated are ordinary Portland cement reactions, and pressure dependent phase fractionation for H (sub 2) O-CO (sub 2) -salt systems. Experimental characterization and video observation of dynamic processes has been collected in supercritical CO (sub 2) industrial reactors. Subsequently, exploration of calculated reaction paths, including phase equilibria of immiscible carbon dioxide and water has allowed evaluation of coupled reaction processes and insight into influence of two fluid phases on mineral equilibria occurring in experimental geochemical reactions. Our research initially focused on the developing issues of anthropogenic carbon dioxide sequestration. Classic questions of the transport, reaction processes and distribution of carbonate minerals, cements and veins in a diverse set of geologic environments are developing new, broader, hypotheses. The diverse presence of carbonate rocks in the Earth's crust, provide ample availability for dynamic hydrothermal and metamorphic systems.

Six wells were drilled to investigate stratigraphic and hydrostratigraphic units, alteration, and structural features in these basins. Location, lithology, stratigraphy, and thickness information are tabulated. Alluvium and volcanic units are thicker in Frenchman Flat compared with Yucca Flat to the north. Correlative volcanic units are present in the upper sections of the three southern wells in Yucca Flat and the Frenchman Flat well. Volcanic units in the lower half of both basins are different. The alluvium contains abundant detrital smectite, zeolites, calcite, and silica and insignificant post-depositional alteration. In situ low-temperature alteration is pervasive in volcanic units, which contain zeolites, smectite, opal-CT, cristobalite, and calcite. Illite, minor chlorite, and pyrite are present in altered granite. Paleozoic rocks are dominated by limestone and dolomite; however, ER-12-2 contains argillite and sandstone with abundant illite, minor smectite, chlorite, kaolinite, calcite, dolomite/ankerite, siderite, and pyrite. Despite limited information from Frenchman Flat, it is evident that thick alluvium and volcanic deposits occur along the axis of both basins compared with areas close to the margins. Thickness variation differences between wells ER-2-1 and ER-7-1, located on the west and east sides of Yucca Fault, respectively, are consistent with deep axial basin profiles created by faulting.

S. government has decided that it is appropriate to proceed with the preparation of a License Application to dispose of high-level radioactive waste at Yucca Mountain. Hydrogeologic site characterization studies of the Saturated Zone (SZ) during the past twenty or more years have built confidence in our understanding of the hydrogeologic setting and fundamental processes controlling groundwater flow and radionuclide migration. This paper summarizes the past suite of characterization and modeling activities of numerous investigators and presents results of recent saturated zone radionuclide transport modeling. In addition, a discussion of future efforts that might be undertaken is presented. In the current Total-System Performance Assessment models for the Yucca Mountain Project, the system as a whole meets performance requirements even though uncertainty in the SZ barrier performance is relatively large. Hydrogeologic variability and conceptual model uncertainties are factors that preclude precise predictions of solute transport in any natural system, and the Yucca Mountain SZ is no exception. Therefore, future work should focus on building confidence in SZ conceptual and numerical models. Potential activities to build confidence in our understanding should, to a large extent, parallel those representing the current state of the art in the science of flow and contaminant transport in groundwater. In the author's opinion, these include: field investigations of the influence of faults on large-scale groundwater flow and contaminant transport; transport field tests combined with laboratory studies aimed at discovering fundamental transport mechanisms; development of integrated, multiscale coupled models of the hydrologic system; application of stochastic hydrology theory to radionuclide transport in the Yucca Mountain SZ; and application of theories and methods for treating uncertainties in conceptual models.

Three single-well injection-withdrawal tracer tests were conducted in saturated alluvium at the Alluvial Testing Complex (ATC) from late November 2000 through April 2001. The tests involved the simultaneous injection of nonsorbing solute tracers with different diffusion coefficients (a halide and a fluorinated benzoate) and the use of three different tracer rest periods in the aquifer before pumping. The tests indicated that the saturated alluvium behaved as a single-porosity system, and they also provided estimates of groundwater flow rates at the site. Laboratory radionuclide batch sorption and column transport experiments have been conducted using representative samples of alluvium along the projected flow pathway(s) from the proposed repository. Unlike previous sorption experiments, which focused primarily on determining partition coefficients (Kd values), these experiments placed greater emphasis on determining the desorption behavior of the radionuclides. Multi-step desorption experiments (repeatedly introducing fresh water to try to induce desorption) and long-duration column experiments were designed to determine distributions of desorption rate constants and to estimate fractions of irreversibly sorbed radionuclides. Finally, column transport experiments have been conducted using Pu (initially Pu(V) in solution) sorbed onto natural colloids collected from the saturated alluvium at the ATC. Results show that colloids smaller than about 200-nm may play a major role in enhancing Pu transport. To our knowledge, these experiments represent the first colloid-facilitated Pu transport experiments conducted using natural colloids, natural water, and natural porous media.

Our previous U-series studies have shown that U, Pa, and Th have remained undisturbed in fractures in the unsaturated zone near the deposit for at least the past 200,000 years; whereas, Ra shows recent (TU>Th, in agreement with the fracture data. In contrast, limited Ra data for saturated zone waters indicate that (super 226) Ra/ (super 238) U activity ratios are less than one, suggesting a relative order of mobility in this environment of U>Ra>Th. This change in Ra mobility between unsaturated and saturated conditions may be due to differences in Ra solubility/complexation or kinetic effects over long transport distances.

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.

While the Navier-Stokes equation is capable of describing flow in detailed geometries at the pore scale, Darcy's law averages the flow over a representative volume. The Brinkman equation includes a viscous resistance term in the Darcy equation to account for solid/fluid interface effects. On the basis of a transient version of the Brinkman equation, we developed a unified lattice Boltzmann (LB) model for flow in multiscale porous media. This model can simulate not only flow in porous media of various length scales but also flow in porous systems where multiple length scales coexist. It has been found that the model recovers Darcy's law when the effects of inertial forces and the Brinkman correction are negligible, and it reduces to the Navier-Stokes equation by specifying zero resistance in the void spaces and infinite resistance on solid walls. This LB model is particularly suitable for simultaneously simulating flow in the fractures and the matrix of fractured porous media. Here, both the Navier-Stokes flow in the fractures and the averaged Darcy flow in the matrix are solved from the same equation with the interface handled internally. This, together with other advantages of the LB method, leads to an efficient approach for simulating flow in multiscale porous media. A number of examples are used to illustrate this LB Brinkman flow model.

The target geologic formations in this category include, depleted oil and gas reservoirs, deep saline aquifers and un-mineable coal beds. Even though improved oil recovery operations have resulted in large-scale injection of CO (sub 2) in depleted oil reservoirs over past 4-5 decades, a number of unknowns still exist regarding the interactions between the host reservoir and injected CO (sub 2) . Further detailed understanding of these interactions is necessary before this option can become a safe, economical and long-term feasible sequestration option. This paper describes results of the laboratory experiments and numerical simulations work performed as part of a DOE sponsored project on CO (sub 2) sequestration in a depleted oil reservoir. The main thrust of this project is characterization of CO (sub 2) migration through a field injection experiment. A depleted oil reservoir near Hobbs, NM, was used for the field demonstration. Laboratory experiments were performed to understand the geochemical interactions that might result due to the introduction of CO (sub 2) in the reservoir. Rock samples from a core from the field were exposed to CO (sub 2) in the presence of brine from the reservoir. The experiments were carried out over a period of 19 months at 700 psi and 40 degrees C. Pre- and post-experiment rock and fluid samples were characterized to understand mineralogic alterations. Rapid dissolution of carbonate minerals and later dissolution of plagioclase feldspars was observed. Trace amounts of clay growth accompanied with feldspar dissolution was also observed. Numerical simulations are currently being performed to develop a computational model for the geochemical interactions observed in the laboratory experiments. Coupled fluid-flow and geochemical reaction models will be developed for the field, based on the laboratory experiments and numerical simulations related to the experiments. These coupled models will ultimately be used to understand long-term impact of CO (sub 2) storage on this reservoir.

Geothermal water (78 degrees C) is used for space heating in a variety of residential, commercial, and public buildings (including the State Capitol). A proposed 50% increase in geothermal water use by the City of Boise led to concern among geothermal water users regarding the potential long-term impacts to the geothermal aquifer system. The purpose of this study was to provide insight and tools for the long-term management of the Boise geothermal aquifer system. The study included a recent, detailed measurement of water levels and/or pressures, refinement of the hydrogeologic framework, and the development of a computer model (using FEHM and PEST) to simulate potential changes in hydraulic heads and water temperatures. Ground water levels in the Boise area show local declines beginning in 1984; water levels began to increase in response to injection of spent geothermal water by the City of Boise in 1999. Initial thermal and hydraulic simulations suggest that the aquifer is able to support the proposed level of increased withdrawals and re-injection. The modeling and model calibration effort helped define future data collection needs to help fill in gaps in understanding of the system.

In many places, these veins originated by reaction of serpentine with immiscible H (sub 2) O-CO (sub 2) fluids in the shallow crust. These natural reactions suggest a means of addressing the continuing rise of global CO (sub 2) emissions: serpentine deposits could be mined and reacted in an analogous aqueous process with CO (sub 2) derived from a power plant. The resulting Mg-carbonate could be buried at the mine site. Serpentine is a highly suitable candidate for mineral sequestration because of its abundance and the stability of the resulting carbonate (magnesite). In this study, we report experimental investigations of the reaction of serpentine in the H (sub 2) O-CO (sub 2) system at moderate T (<200 degrees C) and P (<200 bars). At these conditions, CO (sub 2) dissolves into the aqueous phase but also forms an immiscible H (sub 2) O-bearing phase with properties similar to supercritical CO (sub 2) . Thermodynamic calculations show that the formation of magnesite from serpentine is favorable. The autoclave experiments show that it is possible to rapidly carbonate serpentine in a two-step process: acid dissolution (e.g., HCl) followed by neutralization with a base (e.g., NaOH) and application of CO (sub 2) . However, autoclave experiments with weak acids do not result in magnesite. Our measured dissolution rates of serpentine and geochemical modeling indicate that the moderate pH experiments are limited by a combination of slow dissolution rates and nucleation barriers for magnesite. Fluids associated with natural magnesite veins provide a potential clue to enhanced rates of reactivity: they often contain organic compounds. We have found that dissolution rates can be improved with the use of weak organic acids that complex with Mg (super 2+) . Autoclave experiments with these ligands have demonstrated greatly enhanced dissolution at moderate pH but none have produced magnesite, apparently because the Mg-ligand is resistant to attack by carbonic acid. The natural systems demonstrate that magnesite formation is possible but methods of rapidly reacting serpentine in the laboratory remain elusive.

AN - 51602198; 2006-029649 AB - Over the past decade luminescence dating has been a valuable tool in assessing the timing and frequency of Quaternary fault activity in and around Los Alamos National Laboratory on the Pajarito Plateau of northern New Mexico. Past efforts have utilized both thermoluminescence (TL) and Infrared-stimulated luminescence (IRSL) measurements made on poly-mineral fine-silts. These dating efforts required numerous sub-samples or aliquots to determine one age (multi-aliquot additive dose techniques ? MAAD) and are now considered "traditional" methods. The latest, most advanced optically-stimulated luminescence (OSL) dating techniques are based on measurements made on individual quartz sand grains. These advanced techniques allow hundreds or even thousand of ages to be determined from a single field sample. The resulting data distributions can be objectively scrutinized, leading to more accurate and reliable luminescence ages. In this project we use and compare traditional methods (IRSL MAAD) and advanced techniques, including single-grain laser luminescence (SGLL) measurements, dose distribution analysis, and error deconvolution, to date fluvial sediments from Chupaderos Canyon terraces. The terraces have been faulted and offset by seismic activity on the Guaje Mountain fault. Luminescence dating can provide a depositional chronology for the fluvial sediments that can in turn be used to constrain the timing of seismic activity. Our results indicate that consistent ages can be obtained from both advanced objective techniques and traditional methods, however, a subjective analytical paradigm must be tolerated when considering the IRSL MAAD data. We will also discuss past inconsistencies in traditional luminescence dates from the area, such as age inversions and age over-estimates, in the context of information that can be gathered from dose distributions analysis.

Specimens of Porites lobata were collected from two locations, i.e. the Riau Archipelago, south of Singapore, where the haze was most dense, and the Karimunjawa Islands, north of Central Java, where the effects were less severe. All corals exhibited strong Kinetic Isotope Effects (KIE). On plots of delta (super 18) O vs. delta (super 13) C, shifts in coral metabolism associated with the haze event could be estimated from the distance individual values are positioned from the theoretical KIE line. Skeletons of corals affected by the haze showed decreased delta (super 13) C values, perhaps produced by a shift to a more heterotrophic mode of feeding. These results suggest that wildfires and major forest fire events on tropical coastlines may be recorded in nearby corals, as could temporal variation in frequency of major fires. Moreover, information on coral metabolism may be determined by examining shifts of coral skeletal values in C-O space.

The method has been extensively used in communication theory in estimating probability of rare events. The basic idea behind importance sampling techniques is that certain values of the input random variables (or vectors) have more important impact on the parameters being estimated than others, and if these 'important' values are sampled more frequently than others, i.e. sampled from a biased density function, the variance of the estimator can be reduced. The outputs from simulations are then weighted to correct such biased sampling. Two illustrative examples are given to show the general procedure of the importance sampling approach as well as its applicability to subsurface flow and transport problems. In one example we estimated the mean and variance of hydraulic head for one-dimensional flow, and in the other we estimated the probability of a particle's travel time t less than a given critical value T. In both examples, we compared results from analytical solutions, the conventional Monte Carlo (CMC) simulations, and the importance sampling approach. It is shown that when an importance density function is chosen appropriately, importance sampling techniques may be many orders of magnitude more efficient than the CMC simulations and have a great potential in simulating subsurface flow and transport.

For all but the simplest linear kinetic and sorption models the fate and transport of a reactive solute depends on the residence times and the details of small-scale mixing. The latter phenomenon, also called micromixing, is important because it brings into close proximity chemical species that react, and it controls the local concentrations in a flowing system. Solutes with reaction rates or sorption isotherms that depend on species concentration will therefore be affected by micromixing. Two models for micromixing are introduced, the minimum and maximum mixedness models, that provide bounds on the extent of reaction or retardation behavior within the constraints imposed by the residence time distribution (RTD) of a conservative solute in the same flow system. These mixing models prescribe the latest or earliest permissible mixing of parcels of fluid of different residence times, which in turn bounds the degree of reaction of a reactive solute for nonlinear rate laws or sorption isotherms. Simulation results using the bounding models show that micromixing effects are most important for nonlinear reaction curves, solute pulses of short duration, and systems with broad RTD curves. Use of these models is a straightforward and practical way to investigate the importance of a phenomenon for which data are seldom available and whose impact on groundwater reactive transport models has heretofore not been studied in a systematic, bounding manner.

AN - 85364628; pmid-14587591 AB - A cascade thermoacoustic engine is described, consisting of one standing-wave stage plus two traveling-wave stages in series. Most of the acoustic power is produced in the efficient traveling-wave stages. The straight-line series configuration is easy to build and allows no Gedeon streaming. The engine delivers up to 2 kW of acoustic power, with an efficiency (the ratio of acoustic power to heater power) of up to 20%. An understanding of the pressure and volume-velocity waves is very good. The agreement between measured and calculated powers and temperatures is reasonable. Some of the measured thermal power that cannot be accounted for by calculation can be attributed to Rayleigh streaming in the two thermal buffer tubes with the largest aspect ratios. A straightforward extension of this work should yield cascade thermoacoustic engines with efficiencies of around 35-40% of the Carnot efficiency.

However, legacy nuclear systems are not optimally configured for the new & emerging contingencies of this environment. A common thread likely to run through the desirable characteristics of most future systems is reduced collateral damage (RCD). Improved accuracy enables lower yield weapons to accomplish the missions once allocated to higher yield legacy warheads, with correspondingly reduced collateral effects. Lower yield, earth-penetrating weapons & other new or modified RCD weapons can play a critical role, in conjunction with the other capabilities of the New Triad, in achieving US defense objectives of deterrence, dissuasion, & assurance. As the US implements the Nuclear Posture Review, it is important to assess such capabilities in the context of US defense strategy & to be in a position to develop & deploy them -- if required -- within the much smaller nuclear force toward which the US is moving. 2 Tables, 2 Figures.

AN - 60646471; 200412467 AB - In light of the new strategic environment marred by a combination of uncontrolled nuclear materials & terrorists, the possibility of a layered nuclear material detection & tracking system designed to prevent or mitigate nuclear or radiological attacks on US soil is contemplated. Critical components of such a system include a computer-based information system; counterterrorist-law enforcement agency interface; & real-time data display, assessment, & transfer. Strategic benefits & limitations to such a system are delineated. A nuclear dragnet for homeland security centers on countermeasures to prevent importation, transportation, & detonation of radiological/nuclear devises on US soil. Current efforts at developing & expanding detection systems are identified, addressing the issue of detector network integration as a key factor to any initiative's effectiveness. Potential approaches to deployment of such a multilayered national system for radiation detection is next discussed. Noting US vulnerability to nuclear terrorism, expansion of efforts to deploy some kind of radiation detection system is advocated. J.

Both fractures and deformation bands occur in ignimbrite sequences at Los Alamos, New Mexico, and Busted Butte, Nevada. The primary controls on mode of failure are grain-contact area and strength, which are directly related to degree of welding and crystallization and inversely proportional to porosity. Low-porosity welded units deform by transgranular fracture; high-porosity, glassy, nonwelded units deform by cataclasis within deformation bands. Moderately high porosity, nonwelded units that have undergone devitrification and/or vapor-phase crystallization form either deformation bands or fractures, depending on local variations in the degree and nature of crystallization. Grain- and pore-size reduction in deformation bands commonly produces indurated, tabular zones of clay-sized fault material. Many of these bands are locally rich in smectite and/or cemented by carbonate. Preferential wetting of deformation bands is inferred to promote alteration and cementation. We therefore interpret variably altered fault-zone material as evidence of preferential fluid flow in the vadose zone, which we infer to result from enhanced unsaturated permeability due to pore-size reduction in deformation bands.

The positions of all hydrogen atoms at both ambient and high pressure have been determined by a combination of simulated annealing and energy minimization.

Our method of total station mapping enables recognition of secondary faults, with as little as 30 cm of vertical displacement that are not exposed at the surface, have no topographic expression, and would otherwise likely go unnoticed. It has been applied to preclude the presence of faulting in large areas (several km (super 2) ) of proposed and existing critical facilities at LANL. The method involves surveying of points on geologic features, and detailed computer-aided and field analyses of anomalies in the elevations of surveyed points. We examine vertical anomalies in elevations that are the result of dominantly normal and reverse faulting; however, the method could also be applied to strike-slip faulting. Surveying of geologic contacts allows for easy integration of geologic data into a Geographical Information System (GIS) and detailed 3D analysis of small-scale structures. Field data are analyzed in profiles, 3D surface diagrams, and maps that are constructed with a variety of commercially available software packages. We apply the method to delineate volcanic map-unit boundaries in the 1.2-million-year-old Tshirege Member of the Bandelier Tuff to characterize portions of the Pajarito fault system. The ability of this method to identify faults with very small displacements that otherwise might be unrecognizable allows for discrimination of varying styles of deformation, decreases in displacement along strike through splaying into many smaller faults, monoclinal flexures, and cross structures between faults.

Estimating inventories and detecting changes in the soil C pool have remained elusive, largely because the spatial distribution of soil C varies considerably. New approaches are needed that enable more rapid, cost-effective, and sensitive measurements of soil C and that reduce uncertainty in estimates of C pools and changes in those pools. In this note we extend the application of a new method of total soil C measurement: laser-induced breakdown spectroscopy (LIBS). Carbon analysis using LIBS provides data in seconds from soils with little preparation, whereas conventional methods such as dry combustion require lengthy sample preparation and longer analysis times. Laser-induced breakdown spectroscopy instruments, unlike conventional instruments, can be used while in the field. This promising new method, however, has potential drawbacks, namely interference with Fe at approximately 248 nm. Here we report results of using a different C line at 193 nm to solve the interference problem. We also use a two-element standardization factor to demonstrate that the 193-nm line is nearly as sensitive to C concentration as the C line at 247.8 nm, and that calibration curves can be readily replicated. Overall these results indicate that LIBS is a very promising method to estimate soil C pools and dynamics.

The geological context of the samples are well constrained as they were collected by submersible in an area that has been extensively imaged by remote sensing techniques. Sr, Nd, Hf and (super 208) Pb/ (super 206) Pb isotopic compositions of the off-axis N-MORB are identical to the axial lavas from this same region, suggesting that their sources are similar and that melting processes are the dominant influence in establishing the U-Th-Ra disequilibria and trace element fractionations. A majority of off-axis samples have U-Th and Th-Ra disequilibria that are larger, and model ages that are younger, than would be predicted from their off-axis distance and the time-integrated spreading rate. There are, however, a few off-axis samples with U-Th ages that are consistent with their spreading rate ages. It is likely that these samples erupted within or close to the axial summit trough (AST) and aged at a rate proportional to the spreading rate. The anomalously young ages determined for most of the off-axis lavas suggest that volcanic construction along this region is occurring over a zone that is wider (at least 4 km) than the AST (10s to 100s of meters). The combined observational, chemical and isotopic data support a model for the 9 degrees 0'N area that includes a significant component of crustal accumulation resulting from lavas that breach the AST and flow down the flanks of the EPR ridge crest. However, these data also require a minor component of off-axis eruptions that occur on distinct pillow mounds and ridges. This suggests that MOR construction involves several volcanic and tectonic processes acting in concert to form a complex patchwork of lava ages and compositions along, and across, this fast spreading ridge crest.

In this type of circuit, a regulator protein acts to coordinately repress the expression of effector genes when a signal molecule with which it interacts is present. The regulator protein can also independently influence the expression of its own gene, such that regulator gene expression is repressible (like effector genes), constitutive, or inducible. Thus, a signal-directed change in the activity of the regulator protein can result in one of three patterns of coupled regulator and effector gene expression: direct coupling, in which regulator and effector gene expression change in the same direction; uncoupling, in which regulator gene expression remains constant while effector gene expression changes; or inverse coupling, in which regulator and effector gene expression change in opposite directions. We have investigated the functional consequences of each form of coupling using a mathematical model to compare alternative circuits on the basis of engineering-inspired criteria for functional effectiveness. The results depend on whether the regulator protein acts as a repressor or activator of transcription at the promoters of effector genes. In the case of repressor control of effector gene expression, direct coupling is optimal among the three forms of coupling, whereas in the case of activator control, inverse coupling is optimal. Results also depend on the sensitivity of effector gene expression to changes in the level of a signal molecule; the optimal form of coupling can be physically realized only for circuits with sufficiently small sensitivity. These theoretical results provide a rationale for autoregulation of regulator genes in repressible gene circuits and lead to testable predictions, which we have compared with data available in the literature and electronic databases.

AN - 75726577; 14521430 AB - Organic vapor adsorption rates in air-purifying respirator cartridges (and other packed beds of activated carbon granules) need to be known for estimating service lives. The correlation of Lodewyckx and Vansant [AIHAJ 61:501-505 (2000)] for mass transfer coefficients for organic vapor adsorption onto activated carbon was tested with additional data from three sources. It was then extended to better describe all the data, including that for gases. The additional parameter that accomplished this was the square root of molar equilibrium capacity of the vapor or gas on the carbon. This change, along with skew corrections when appropriate, resulted in better correlations with all experimental rate coefficients.

The fate of weathering minerals or sediment-bound constituents in fluvial environments depends on the relative time scales of constituent degradation and particle residence time within valleys. Particles follow a set of trajectories through valley floors: some particles pass directly through the channel, reaching the basin outlet rapidly after being introduced to the fluvial system; others remain for long periods in deposits such as flood plains. Traditional sediment routing theory, based on the principle of sediment mass conservation along reaches of channel, does not account for exchanges of sediment with temporary sediment storage reservoirs outside the channel, such as flood plains, deltas, and alluvial fans. This article formalizes a theory that incorporates the role of such exchanges in the migration of sediment through river systems, by computing the probabilistic structure of particle trajectories through alluvial valley floors. Equations are developed for computing these trajectories from the sediment budget of a valley floor in steady state. Mathematical strategies for using such relationships to model transient storage conditions are proposed, and other potential model enhancements are discussed. The approach is illustrated using a hypothetical valley floor as an example. The theory can be used to examine rates of sediment overturn in valleys, map particle residence times, and account for the redistribution and decomposition of weathering minerals and particle-bound constituents. The theory has numerous potential management applications, some of which are discussed herein. The hypothetical example demonstrates that the probability distribution of particle residence times in the valleys of most alluvial rivers should be strongly right skewed.

Although not in complete agreement with experimental values, the promising results suggest additional work and continued research for optimal parameters. Accommodating modifications in the SOURCES code system required improved data and an approximation for the three-body reaction branching fractions is presented as a temporary solution. Experimental spectra from AcBe, CmBe, and simulated AmBe neutron sources are compared to SOURCES calculations using the new branching fractions and serve as benchmarks for this new version of the code.

It is often computationally expedient to determine the mean values of state variables (pressure heads, velocity) by replacing spatially varying (random) local conductivities with their effective or apparent counterparts. We explore the concept of apparent parameters for formations with uncertain spatial arrangement of geological facies and hydraulic properties within each facies. Our analysis relies on the composite media theory, which employs random domain decomposition to explicitly account for the separate effects of material and geometric uncertainty on ensemble moments of head and flux. We present a general expression for the apparent conductivity of such media and analyze it in detail for one-dimensional steady flow in a bounded random medium composed of two materials of contrasting hydraulic conductivities. Location of the internal boundary between the two materials is random and normally distributed. The resulting apparent conductivity is compared with approximate perturbation solutions.

Samples of river water, hot springs, and cold springs were collected at 25 locations during November 1994, March 1996, and June 1996. Arsenic and other trace metal analyses were performed by graphite furnace and hydride generator atomic absorption spectroscopy for acidified unfiltered samples. Concentrations along the Jemez River ranged from 2 to 300 micrograms per liter (mu g/L). Seven of ten locations exceeded the current EPA arsenic drinking water standard of 10 mu g/L. These seven locations were at or downstream of the Jemez Springs area where roughly 1,500 L/min of thermal water enters the river from the Valles caldera geothermal system. In the Jemez Springs area, the thermal water can be sampled directly from Soda Dam hot spring and Travertine Mound hot spring. Discharge from these hot springs flows directly into the Jemez River. From Soda Dam hot spring, the arsenic concentration was 1,770 mu g/L and the mass flow rate was 0.02 kg/day. The Travertine Mound hot spring arsenic concentration was 830 mu g/L, and the mass flow rate was 0.001 kg/day. The highest arsenic mass flow rate on the Jemez River was approximately 6 kg/day at a location below Soda Dam hot spring and decreased to 0.1 kg/day below the Jemez Canyon Dam. All six sampling locations along the Rio Grande between Espanola and Bernalillo had arsenic concentrations less than 10 mu g/L. The Rio Grande showed no difference in arsenic concentrations above and below the confluence with the Jemez River. Discharge of the Rio Grande was about 30 times greater than the Jemez River. The arsenic mass flow rate of the Rio Grande during June 1996 was approximately 6 kg/day.

The Consortium members hope to work together with other M. tuberculosis researchers to identify M. tuberculosis proteins for which structural information could provide important biological information, to analyze and interpret structures of M. tuberculosis proteins, and to work collaboratively to test ideas about M. tuberculosis protein function that are suggested by structure or related to structural information. This review describes the TB Structural Genomics Consortium and some of the proteins for which the Consortium is in the progress of determining three-dimensional structures.

Compounding the scarcity issue is the fact that much of the water is also of poor quality. In recent years, the quest for sources of fresh water has intensified as the realization of the potential for long-term water shortages becomes a reality. This paper examines the definition of 'fresh' water as a function of the end use of the water, i.e. human consumption, environmental release, or reuse for industrial or municipal applications. It is within this context that a discussion of the term 'fresh' is evaluated as a defining criterion for potential sources. The technology to produce good quality water from poor quality sources exists. However, factors other than technology often control the decision making as to whether to treat a water source of poor quality, or continue to look for a source of higher quality. Some of these factors are: public acceptance, environmental impact, regulations, economics, human health risks, regional issues, political issues. The specific case discussed here uses a wastewater source that is highly controversial by its very nature, as it contains radionuclides and other industrial contaminants. The factors leading to this source being considered are as follows: (1) the municipal water production wells are 1500-2000 ft. 457.5-610 m) below the surface making production costly; (2) the groundwater quantity is limited and recharge is extremely slow; and, (3) the groundwater has a high level of naturally occurring silica (80-120 mg/l The case facility, located in western portion of the United States, treats an average of 15, 000 gpd (57 m super(3)/d through the use of chemical precipitation, sand filtration, ultrafiltration, ion exchange and reverse osmosis. The secondary waste (reject or concentrate) from this treatment process is further treated with electrodialysis-reversal and mechanical evaporation. The product from this facility is currently discharged, by regulatory permit, to the environment. The product water is being considered for reuse primarily for industrial applications.

A Langmuir adsorption model was used in a thermodynamic analysis of the isothermal adsorption data for the W5 site together with a symmetrical regular solution model. Resulting values for the standard molar Gibbs energy and entropy of hydration of the W5 site relative to liquid water are -8430+ or -113 J/mol and -16.7+ or -2.1 J/(mol.K), respectively, and the Margules parameter, W (sub G) , is 1590+ or -63 J/mol. The standard enthalpy of hydration of the W1 site was determined by liquid-water immersion calorimetry experiments on laumontite containing vacant W1 and fully occupied W5, W2, and W8 sites. Discontinuous hydration and dehydration of W1 at 23.4+ or -0.7 degrees C and 24+ or -1 mbar PH (sub 2) O was used to constrain the molar Gibbs energy of hydration of this site. Resulting values for standard molar Gibbs energy of hydration and enthalpy of W1 relative to liquid water are -380+ or -170 and -8800+ or -1150 J/mol, respectively. Isothermal adsorption at 23.4 degrees C and isobaric thermogravimetric experiments indicate that during dehydration of W1, only 0.83 moles of water are released from the crystal structure and 0.17 moles are relocated to a disordered site that has energetic properties similar to the W8 site. Calculations using the thermodynamic data determined in this study indicate that the water content of laumontite in equilibrium with liquid water ranges from approximately 4.5 H (sub 2) O per 12 framework O atoms at room temperature and one bar pressure to approximately 3.5 H (sub 2) O at 250 degrees C and at liquid-vapor saturation pressure for water.

A detailed analysis of the production and propagation of sonic waves during the atmospheric entry of the Moravka meteoroid demonstrates that the acoustic energy was produced both by the hypersonic flight of the meteoroid (producing a cylindrical blast wave) and by individual fragmentation events of the meteoroid, which acted as small explosions (producing quasispherical shock waves). The deviation of the ray normals for the fragmentation events was found to be as much as 30 degrees beyond that expected from a purely cylindrical line source blast. The main fragmentation of the bolide was confined to heights above 30 km with a possible maximum in acoustic energy production near 38 km. Seismic stations recorded both the direct arrival of the airwaves (the strongest signal) as well as air-coupled P-waves and Rayleigh waves (earlier signals). In addition, deep underground stations detected the seismic signature of the fireball. The seismic data alone permit reconstruction of the fireball trajectory to a precision on the order of a few degrees. The velocity of the meteoroid is much less well-determined by these seismic data. The more distant infrasonic station detected 3 distinct signals from the fireball, identified as a thermospheric return, a stratospheric return, and an unusual mode propagating through the stratosphere horizontally and then leaking to the receiver.

The pre-atmospheric mass of the meteoroid was computed from fireball radiation, infrasound, seismic signal, and the content of noble gases in the meteorites. All methods gave consistent results. The best estimate of the pre-atmospheric mass is 1500+ or -500 Kg. The fireball integral bolometric luminous efficiency was 9%, and the acoustic efficiency was 0.14%. The meteoroid cosmic ray exposure age was determined to be (6.7+ or -1.0)X10 (super 6) yr. The meteorite shows a clear deficit of helium, both (super 3) He and (super 4) He. This deficit can be explained by solar heating. Numerical backward integration of the meteoroid orbit (determined in a previous paper from video records of the fireball) shows that the perihelion distance was probably lower than 0.5 AU and possibly as low as 0.1 AU 5 Ma ago. The collision which excavated Moravka probably occurred while the parent body was on a near-Earth orbit, as opposed to being confined entirely to the main asteroid belt. An overview of meteorite macroscopic properties, petrology, mineralogy, and chemical composition is given. The meteorites show all mineralogical features of H chondrites. The shock level is S2. Minor deviations from other H chondrites in abundances of trace elements La, Ce, Cs, and Rb were found. The ablation crust is enriched with siderophile elements.

Experiments were conducted in a flexible cell hydrothermal apparatus to determine the extent of fluid-rock reactions, in addition to carbonate mineral precipitation, that may occur in a brine aquifer-aquitard system that simulates a saline aquifer storage scenario. The system was held at 200 degree C and 200 bars for 59 days (1413 h) to approach steady state, then injected with CO sub(2) and allowed to react for another 80 days (1924 h). In addition to magnesite precipitation, silicate minerals (quartz, plagioclase, microcline and biotite) in the aquifer and the aquitard display textures (etch pits, mineralization) indicating significant reaction. Changes in elemental abundances in the brine following addition of CO sub(2) include pH decrease and enrichment in Cl super(-), partly due to supercritical CO sub(2) desiccation of the brine. Geologic sequestration systems have potential for geochemical reactions that extend beyond simple aqueous dissolution of CO sub(2) and precipitation of carbonate. These reactions may produce geochemical and geotechnical consequences for sequestration and provide important characteristics for monitoring and evaluation of stored CO sub(2). An understanding of multi-phase equilibrium relationships between supercritical CO sub(2) and aquifer-brine systems also raises new questions for a variety of geologic systems. Multi-phase fluid equilibria may, for example, account for the large amounts and heterogeneous distributions of calcite cement in a wide variety of geologic systems, particularly in sedimentary basin sandstones.

Standard protocols, such as immunoprecipitation, western blotting and immunofluorescence, can be used with antibody fragments generated by display technologies. Together with novel approaches, such as antibody chips and intracellular immunization, these methods will yield useful proteomic data following adaptation of the protocols for increased reliability and robustness. To date, most work has focused on the use of standard, well-characterized commercial antibodies. Such protocols need to be adapted for broader use, for example, with antibody fragments or other binders generated by display technologies, because it is unlikely that traditional approaches will provide the required throughput.

Data were corrected for adsorbed water, the only significant impurity to the ideal formula Al (sub 2) Si (sub 2) O (sub 5) (OH) (sub 4) . Enthalpies of dickite dissolution into molten lead borate at 702 degrees C and of dickite formation from the oxides and from the elements at 25 degrees C and 1 bar are 356.3+ or -3.3 kJ/mol, -31.1+ or -4.2 kJ/mol, and -4099.8+ or -4.8 kJ/mol, respectively. Using entropy data from the literature, the standard Gibbs free energy of dickite formation from the elements at 25 degrees C is -3777.5+ or -4.8 kJ/mol. This value is 7 to 25 kJ/mol more endothermic than literature values obtained for other dickites by calculations, solubility measurements, or calorimetry. Since the Saint Claire dickite is almost pure, the applied corrections are very small and these results are likely to be the most reliable of the available data. The Gibbs free energy of formation of the Saint Claire dickite at 25 degrees C and 1 bar is 12 to 25 kJ/mol less negative than data obtained for kaolinite using the same and different techniques. This trend is unlikely to reverse at higher temperature and/or pressure in the range of kaolin mineral occurrences. Thus, the new data further corroborate our earlier findings that dickite is thermodynamically metastable relative to kaolinite. This is in agreement with results obtained by mineral synthesis and with most of the observations of kaolinite and dickite occurrences in natural environments. However, further investigations are required to fully explain the transformation of kaolinite to dickite, which appears to occur during diagenesis.

Difference Fourier maps clearly showed H atoms positions near those O atoms at the midpoints of the tunnel edges. The O-H vectors point toward the Cl sites at the center of the tunnel, and weak hydrogen bonds likely form between the framework O atoms and Cl. The Cl position is near the center of a prism defined by the eight hydroxy1 H atoms. The Cl atoms fill approximately 2/3 of the tunnel sites, suggesting an ordering scheme in a given tunnel with every third tunnel site vacant. Such an arrangement allows the Cl anions to increase their separation distance along a tunnel by displacing away from one another toward their respective adjacent vacancies. The Fe-O octahedra in akaganeite are distorted with Fe-(O, OH) distances ranging from 1.94 to 2.13 Aa and show three longer and three shorter Fe-O distances; as expected the longer distances are associated with the OH-anions. Temperature-resolved synchrotron X-ray powder diffraction data and Rietveld refinements were used to investigate changes in the akaganeite structure and its transformation into hematite as it was heated from 26 to 800 degrees C. Rietveld refinements revealed surprising consistency in all unit-cell parameters between room temperature and approximately 225 degrees C, resulting in nearly zero thermal expansion of the akaganeite structure over a 200 degrees C interval. Above approximately 225 degrees C, the unit-cell volume gradually decreased, primarily in response to decreases in c and b, and an increase in the beta angle.

The explosions were conducted in a mine in northeast Wyoming where delay-fired explosions occur regularly. The primary observational data sets consist of close-in measurements in the mine and regional observations at the International Monitoring System Primary array at Pinedale, Wyoming (PDAR). The single-fired explosions ranged in size from 5500 to 50,000 1b and were separated from one another from 30 m to over 4 km. Peak amplitude measures at a single element of the regional array are well matched with a power law dependence on explosive weight. Similar scaling constants were determined for each of the dominant regional phases: P (sub n) , 0.84+ or -0.14; P (sub g) , 0.84+ or -0.09; and L (sub g) , 0.91+ or -0.08. Peak amplitudes across PDAR show a factor of 3 variation for an individual explosion across all array elements. This amplitude variation is accompanied by a decrease in spatial correlation with increasing station separation indicating the importance of near-receiver structure. The regional signals were further characterized by computing frequency-dependent envelope functions at each array element. Consistent source scaling factors at a single array element were obtained from the envelope functions. A high degree of spatial variability as a function of frequency was documented for the envelope functions. Spectral ratios are used to investigate source scaling relations for the different explosions. Four similarly prepared shots with total explosive weights between 5500 and 6000 1b were detonated to investigate source repeatability. Spectral ratio analysis identified two of the four shots as only partially detonating, resulting in a reduction of long-period spectral level by factors of 10 and 50. These long-period reductions were accompanied by increases in source corner frequency, consistent with a smaller source size. Spectral ratios of waveforms from the larger explosions that fully detonated illustrate that P (sub g) and L (sub g) source functions are similar. The empirical source ratio is well modeled with a Mueller-Murphy source model. These experiments and the resulting data analysis suggest that simple, single-fired explosions of modest explosive weight can be used to calibrate regional seismic arrays, networks, and individual stations.

There is common isotopic disequilibrium between the two fractions. It is suggested that the trace element and isotopic composition of the carbonate fraction better represents that of the carbonatite magma, which in turn better reflects the composition of the carbonatitic source. Experimental partitioning data between carbonatite melt and peridotitic mineralogy suggest that the Lu/Hf ratio of the source will be 5 the Lu/Hf ratio of the carbonatite. This, combined with the Hf systematics of carbonatites, suggests that if carbonatites are primary mantle melts, then their sources must be short-lived features in the mantle (maximum age 10-30 m.y.), otherwise they could develop extremely radiogenic Hf compositions. A model is presented in which the carbonatite source is created in the sublithospheric mantle by crystallization of earlier carbonatite melts from a mantle plume. This new source would melt soon after its formation by the excess heat provided by the approaching hotter centre of the plume and/or the subsequent ascending silicate melts.

The main aim of this work was to qualitatively and quantitatively characterize the conditions suitable for HFEPR of high-spin transition metal complexes in frozen solutions, and compare them with experiments performed on solid samples. Mn(TSP) is a porphyrin complex soluble in water, in contrast to most metalloporphyrins. Mn(salen), often referred to as Jacobsen's catalyst, is a complex widely used in organic synthesis for alkene epoxidation, and is soluble in organic solvents. High-quality HFEPR signals were observed for solid state Mn(TSP), as has been previously shown for many Mn(III) complexes. The present study is, however, the first to report high-quality HFEPR spectra of a Mn(III) complex in frozen aqueous solution. Analysis of the data yielded the following spin Hamiltonian parameters: S = 2; D = -3.16 plus or minus 0.02 cm super(-1), E = 0, and isotropic g = 2.00(2). No X-band EPR signals were observed for Mn(TSP), which is a consequence of this being a rigorously axial spin system. Mn(salen), in contrast, did not give good quality HFEPR spectra in the solid state, but high-quality HFEPR spectra were recorded in frozen organic solutions. Analysis of the data yielded the following spin Hamiltonian parameters: S = 2; D = -2.47 plus or minus 0.02 cm super(-1), parallel E parallel = 0.17 plus or minus 0.01 cm super(-1), and isotropic g = 2.00(2). These values differ from those reported using X-band parallel mode EPR [J. Am. Chem. Soc. 123 (2001) 5710], as discussed in the text. Therefore, a comparison between HFEPR and parallel-mode X-band spectroscopy is made. Finally, the concentration sensitivity aspect of HFEPR spectroscopy is also discussed.

In a 2-year field study, seasonal abundance measurements were conducted for fast-growing bacterial heterotrophs, humate-degrading actinomycetes, fungal heterotrophs, and fluorescent pseudomonads that represent the decomposers in soil. Links between plant health and soil microbiota abundance in pinyon rhizospheres were documented across two soil types: a dry, nutrient-poor volcanic cinder field and a sandy-loam soil. On the stressful cinder fields, we identified relationships between soil decomposer abundance, pinyon age, and stress due to insect herbivory. Across seasonal variation, consistent differences in microbial decomposer abundance were identified between the cinders and sandy-loam soil. Abundance of bacterial heterotrophs and humate-degrading actinomycetes was affected by both soil nutritional status and the pinyon rhizosphere. In contrast, abundance of the fungal heterotrophs and fluorescent pseudomonads was affected primarily by the pinyon rhizosphere. On the cinder field, the three bacterial groups were more abundant on 150-year-old trees than on 60-year-old trees, whereas fungal heterotrophs were unaffected by tree age. Fungal heterotrophs and actinomycetes were more abundant on insect-resistant trees than on susceptible trees, but the opposite was true for the fluorescent pseudomonads. Although all four groups were present in all the environments, the four microbial groups were affected differently by the pinyon rhizosphere, by tree age, and by tree stress caused by the cinder soil and insect herbivory.

The method uses a single-stranded, fluorescent DNA probe, 464 nucleotides in length, derived from a B. anthracis 16S rRNA gene. The probe contains a unique, engineered deletion such that all probe-target duplexes are heteroduplexes with an unpaired G at position 343 ([Delta] G343). Heteroduplex profiles of sequences => 85% similar to the probe were produced using an ABI 377 sequencer in less than 3 h. The method divides strains of the Bacillus cereus-Bacillus thuringiensis-B. anthracis group into two subgroups. Each subgroup is defined by a specific 16S rRNA gene sequence type. Sequence type A, containing one mismatch with the probe, occurs in B. anthracis and a small number of closely related clonal lineages represented mostly by food-borne pathogenic isolates of B. cereus and B. thuringiensis. Sequence type B, containing two mismatches with the probe, is found in the majority of B. cereus and B. thuringiensis strains examined to date. Sequence types A and B, when hybridized to the probe, generate two easily differentiated heteroduplexes. Thus, from heteroduplex profiles, the presence of B. cereus-B. thuringiensis-B. anthracis subgroups in environmental samples can be inferred unambiguously. The results show that fluorescent heteroduplex analysis is an effective profiling technique for detection and differentiation of sequences representing small phylogenetic or functional groups in environmental samples.

There were significant intra-annual and interannual differences in the carbon isotope ratios of CO sub(2) respired at both the ecosystem ( delta super(13)C sub(R)) and the soil levels ( delta super(13)C sub(R-soil)), but only limited variations in the carbon isotope ratios of carbon stocks. The delta super(13)C sub(R) values varied by as much as 4.4 over a growing season, while delta super(13)C sub(R-soil)values changed as much as 6.2. The delta super(13)C of soil organic carbon ( delta super(13)C sub(SOC)) and needle organic carbon ( delta super(13)C sub(P)) exhibited little or no significant changes over the course of this study. Carbon isotope discrimination within leaves ( Delta sub(p)) showed systematic decreases with increased canopy height, but remained fairly constant throughout the year ( Delta sub(p)=17.9-19.2 at the top of the canopy, Delta sub(p)=19.6-20.9 at mid-canopy, Delta sub(p)=23.3-25.1 at the canopy base). The temporal variation in the delta super(13)C of soil and ecosystem respired CO sub(2) was correlated (r=0.93,P<0.001) with soil moisture levels, with dry summer months having the most super(13)C-enriched values. The dynamic seasonal changes in delta super(13)C of respired CO sub(2) are hypothesized to be the result of fast cycling of recently fixed carbon back to the atmosphere. One scaling consequence of the seasonal and interannual variations in delta super(13)C sub(R) is that inversion-based carbon-cycle models dependent on observed atmospheric CO sub(2) concentration and isotope values may be improved by incorporating dynamic delta super(13)C sub(R) values to interpret regional carbon sink strength.

This has resulted in a desire to perform similarly broad experiments on all the proteins encoded by a genome. Panels of specific antibodies, or other binding ligands, will be essential tools in this endeavour. Because traditional immunization will be unlikely to generate antibodies in sufficient quantity, and of the required quality and reproducibility, in vitro selection methods will probably be used. This review - the first of two - examines the strategies available for in vitro antibody selection. The second review discusses the adaptation of these methods to high throughput and the uses to which antibodies, once derived, can be put.

Published data was used to estimate the photoconductance, convergence/divergence ratios, synaptic transfer functions, passive membrane properties and voltage-gated conductances, the latter using a Levenberg-Marquardt search algorithm. When the cone resting potential was sufficiently depolarized, synaptic feedback from horizontal cells could account for the flash response measured experimentally. Voltage-gated conductances were not significantly activated during the flash response but rather maintained the cone membrane potential inside a narrow physiological range.

PA combines with EF and LF to form bipartite PA-EF and PA-LF toxins and facilitates intracellular delivery of EF and LF both of which cause cytotoxicity to the host. Since the level of PA is crucial to pathogenesis by anthrax toxins, it is important to understand how the host environment regulates the expression of the PA (or pagA) gene by utilizing the 5' and 3' untranslated regions (UTR). The 5' UTR sequence determines the initiation of transcription, whereas the 3' UTR sequence determines the efficient termination and stability of the transcript. Although, the role of the 5'UTR sequence of pagA has been investigated, little is known about the role of the 3' UTR. Since hairpin formation at the 3'UTR of a gene is an established mechanism for efficient termination and stability of the transcript, we carried out structural studies, including gel electrophoresis, circular dichroism, and two-dimensional nuclear magnetic resonance spectroscopy, to determine whether the 3' UTR sequences of pagA also form hairpin structures. Our results unequivocally demonstrate that both the coding and the noncoding 3' UTR sequences form stable hairpin structures. It is quite likely that the hairpins at the 3'UTR may contribute to efficient termination and stability of the pagA transcript.

AN - 73412467; 12830898 AB - Waste management programs at the Radioactive Liquid Waste Treatment Facility (RLWTF) at the Los Alamos National Laboratory (LANL) are concerned with the levels of perchlorates due to the effects it can have on the environment and resultant regulations. The RLWTF treats industrial and radioactive wastes generated at multiple research and production facilities across the LANL. Perchloric acid is the major source of the perchlorate ion in the RLWTF used in the analytical chemistry laboratories and for metal dissolution. Perchlorate is present in the influent to the RLWTF at concentrations up to several thousands microg/l level. Ion chromatography is the method of choice to analyze the concentrations of perchlorate in the wastewater generated at the RLWTF. Perchlorate was separated by elution through a CS16/CG16 with an EG40 eluent generator. To minimize background conductivity and enhance analyte conductance, an anion self-regenerating suppressor was used. The method achieved a perchlorate method detection limit of 1 microg/l. The method is successfully being used to monitor the perchlorate levels at the RLWTF and provide data for the pilot tests to remove perchlorate from the RLWTF effluent.

AN - 73429101; 12809534 AB - The continued occurrence of chronic beryllium disease (CBD) suggests the current occupational exposure limit of 2 microg beryllium per cubic meter of air does not adequately protect workers. This study examined the morphology and measured the particle surface area of aerodynamically size-separated powders and process-sampled particles of beryllium metal, beryllium oxide, and copper-beryllium alloy. The beryllium metal powder consisted of compact particles, whereas the beryllium oxide powder and particles were clusters of smaller primary particles. Specific surface area (SSA) results for all samples (N=30) varied by a factor of 37, from 0.56 +/- 0.07 m(2)/g (for the 0.4-0.7 microm size fraction of the process-sampled reduction furnace particles) to 20.8 +/- 0.4 m(2)/g (for the 6 microm) to 20.8 +/- 0.44 m(2)/g (for the particle size fraction 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 model is based on a two-dimensional, cross-sectional, dual-permeability model of the unsaturated zone at Yucca Mountain and uses a stochastic approach to investigate the effect of small-scale heterogeneous features. The studies were conducted using one uniform fracture permeability case, three realizations of stochastically generated fracture permeability, one discrete permeability feature case, and one increased ambient liquid flux case. In all cases, the models predict that completely dry drift conditions will develop above and below the drift in 10-100 years and remain dry for 1000-2000 years. During this period, the models predict no seepage into drifts, although liquid flux above the drifts and within the drift pillars may increase by up to two orders of magnitude above ambient flux. This is because the heat released by the emplaced waste is sufficient to vaporize liquid flux of one to two orders of magnitude higher than present-day ambient flux for over 1000 years. The results also show that unsaturated zone thermal-hydrological (TH) models with uniform layer permeability can adequately predict the evolution of seepage and moisture distribution in the rock mass surrounding the repository drifts. The models further show that although variability in fracture permeability may focus and enhance liquid flow in regions of enhanced liquid saturation (due to condensation above the drifts), vaporization and vapor diffusion can maintain a dry environment within the drifts for thousands of years.

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.

Seepage is a key factor affecting the performance of the potential nuclear-waste repository at Yucca Mountain, Nevada. Three-dimensional numerical models were developed to simulate field tests in which water was released from boreholes above excavated niches. Data from air-injection tests were geostatistically analyzed to infer the heterogeneous structure of the fracture permeability field. The heterogeneous continuum model was then calibrated against the measured amount of water that seeped into the opening. This approach resulted in the estimation of model-related, seepage-specific parameters on the scale of interest. The ability of the calibrated model to predict seepage was examined by comparing calculated with measured seepage rates from additional experiments conducted in different portions of the fracture network. We conclude that an effective capillary strength parameter is suitable to characterize seepage-related features and processes for use in a prediction model of average seepage into potential waste-emplacement drifts.

In this study, parallel computing techniques, as implemented into the TOUGH2 code, are applied in large-scale numerical simulations on a distributed-memory parallel computer. The modeling study has been conducted using an over-1-million-cell three-dimensional numerical model, which incorporates a wide variety of field data for the highly heterogeneous fractured formation at Yucca Mountain. The objective of this study is to analyze the impact of various surface infiltration scenarios (under current and possible future climates) on flow through the UZ system, using various hydrogeological conceptual models with refined grids. The results indicate that the 1-million-cell models produce better resolution results and reveal some flow patterns that cannot be obtained using coarse-grid modeling models.

As part of an ongoing effort to evaluate thermal-hydrological-chemical (THC) effects on flow in fractured media, we performed a laboratory experiment and numerical simulations to investigate mineral dissolution and precipitation under anticipated temperature and pressure conditions in the repository. To replicate mineral dissolution by vapor condensate in fractured tuff, water was flowed through crushed Yucca Mountain tuff at 94 degrees C. The resulting steady-state fluid composition had a total dissolved solids content of about 140 mg/l; silica was the dominant dissolved constituent. A portion of the steady-state mineralized water was flowed into a vertically oriented planar fracture in a block of welded Topopah Spring Tuff that was maintained at 80 degrees C at the top and 130 degrees C at the bottom. The fracture began to seal with amorphous silica within 5 days. A 1-D plug-flow numerical model was used to simulate mineral dissolution, and a similar model was developed to simulate the flow of mineralized water through a planar fracture, where boiling conditions led to mineral precipitation. Predicted concentrations of the major dissolved constituents for the tuff dissolution were within a factor of 2 of the measured average steady-state compositions. The mineral precipitation simulations predicted the precipitation of amorphous silica at the base of the boiling front, leading to a greater than 50-fold decrease in fracture permeability in 5 days, consistent with the laboratory experiment. These results help validate the use of a numerical model to simulate THC processes at Yucca Mountain. The experiment and simulations indicated that boiling and concomitant precipitation of amorphous silica could cause significant reductions in fracture porosity and permeability on a local scale. However, differences in fluid flow rates and thermal gradients between the experimental setup and anticipated conditions at Yucca Mountain need to be factored into scaling the results of the dissolution/precipitation experiments and associated simulations to THC models for the potential Yucca Mountain repository.

Analyses of samples of only a few milliliters of pore water extracted by uniaxial or triaxial compression and by ultracentrifugation methods from adjacent core samples are generally in agreement, within the analytical error of 10% to 15%. However, the values of silica for water obtained by ultracentrifugation are consistently lower than values for water obtained by compression. The larger concentrations probably are due to localized pressure solution of silicate minerals during compression. The shallower water from core in borehole USW SD-6 was extracted from nonwelded units collectively referred to as the Paintbrush Tuff nonwelded (PTn). The deeper water was from core in both boreholes USW SD-6 and USW WT-24 in the nonwelded units referred to as the Calico Hills nonwelded (CHn). Significant differences in mean dissolved-ion concentrations in pore water between the PTn and CHn are (1) decreases in Ca, Mg, SO (sub 4) , and NO (sub 3) and (2) increases in HCO (sub 3) and (Na+K)/(Ca+Mg) ratios. The decrease in NO (sub 3) and the increase in HCO (sub 3) could be the result of denitrification through the oxidation of organic matter. The decrease in Ca and associated increase in (Na+K)/(Ca+Mg) is the result of ion exchange with zeolites in the CHn in borehole USW WT-24. This effect is not nearly as pronounced in borehole USW SD-6, probably reflecting a smaller amount of zeolitization of the CHn in USW SD-6. Geochemical calculations using the PHREEQC code indicate that the pore water from both boreholes USW SD-6 and USW WT-24 is uniformly undersaturated in anhydrite, gypsum, and amorphous silica, but supersaturated in quartz and chalcedony. The saturation of calcite, aragonite, sepiolite, and dolomite is more variable from sample to sample.

During the experiments, changes in moisture content were monitored within the test bed, and a slot excavated below the test bed was visually inspected for seepage. Our field tests suggest that the dry porous PTn matrix is capable of attenuating episodic percolation fluxes in localized areas (such as around faults) where fast flow would be expected to dominate. Once wetted, the matrix is able to retain the moisture over a period of months. As saturation increases in the matrix, less water imbibes along the fault and more water travels farther along the fault. From this observation, we infer that a sequence of infiltration events separated by periods of up to a few months could convey water over increasing distances along the fault.

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.

However, the usefulness of this approach can be questioned in terms of its adequacy for representing fingering flow and transport in unsaturated fractured rock. The continuum approach thus needs to be evaluated carefully by comparing simulation results with field observations directly related to unsaturated flow and transport processes. This paper reports on such an evaluation, based on a combination of model calibration and prediction, using data from an infiltration test carried out in a densely fractured rock within the unsaturated zone of Yucca Mountain, Nevada. Comparisons between experimental and modeling results show that the continuum approach may be able to capture important features of flow and transport processes observed from the test. The modeling results also show that matrix diffusion may have a significant effect on the overall transport behavior in unsaturated fractured rocks, which can be used to estimate effective fracture-matrix interface areas based on tracer transport data. While more theoretical, numerical, and experimental studies are needed to provide a conclusive evaluation, this study suggests that the continuum approach is useful for modeling flow and transport in unsaturated, densely fractured rock.

The modeling study is based on the current thermal-hydrological (TH) mountain-scale model, which uses a locally refined 2D north-south cross-section and dual-permeability numerical approach. The model provides a prediction of the mountain-scale TH response under the thermal-load scenario of 1.45 kW/m, while accounting for future climatic changes and the effects of drift ventilation. The TH simulation results show that ventilation of the repository drifts has a large impact on thermal-hydrologic regimes and moisture-flow conditions at the repository. In both cases, with and without ventilation, the TH model predicts dry or reduced liquid saturation near the drifts for over 1000 years, during which liquid flux through the drifts is reduced to either zero or less than the ambient flux. Without ventilation, the model predicts higher temperatures at the repository, but no major moisture redistribution in the UZ except in the areas very near the heated drifts.

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.

Simulations of radionuclide migration in the SZ have been performed using the calibrated three-dimensional (3-D) SZ site-scale flow and transport model. An innovative particle-tracking method was used to simulate transport that includes the processes of advection, dispersion, matrix diffusion, and sorption. The uncertainties in groundwater flow and radionuclide transport were quantitatively evaluated to develop uncertainty distributions for key model parameters, and multiple realizations of the SZ system were simulated using the SZ site-scale model. The results of multiple realizations of radionuclide transport indicate significant aggregate uncertainty in transport times through the SZ. The simulated radionuclide mass breakthrough curves in the SZ have been coupled with other components of the repository system in Total System Performance Assessment (TSPA) analyses and constitute the means by which uncertainty in the SZ is incorporated into regulatory analyses. Regression analysis has been used to determine the sensitivity of radionuclide transport simulation results to the uncertainty of individual model input parameters. Results of the sensitivity analysis indicate that median radionuclide transport times were dominantly controlled by uncertainty in the specific discharge in the SZ, with sorption and retardation in the alluvium playing important roles for some radionuclides.

Different periods of site characterization activities and prominent issues concerning the unsaturated zone (UZ) are summarized. Data collection activities have evolved from mapping of faults and fractures to estimation of percolation through tuff layers, and to quantification of seepage into drifts. Evaluation of discrete flow paths in drifts has led to fracture-matrix interaction and matrix diffusion tests over different scales. The effects of tuff interfaces and local faults are evaluated in fractured-welded and porous-nonwelded units. Mobilization of matrix water and redistribution of moisture are measured in thermal tests. Lessons learned from underground tests are used to focus on processes needed for additional quantification. Migration through the drift shadow zone and liquid flow through faults are two important issues that have evolved from current knowledge.

Drifts in which waste packages will be emplaced are subject to degradation in the form of rockfall from the drift ceiling, induced by stress-relief, seismic, or thermal effects. The objective of this study is to calculate seepage rates, for various drift-degradation scenarios and for different values of percolation flux, in the Topopah Spring middle nonlithophysal (Tptpmn) and the Topopah Spring lower lithophysal (Tptpll) units at Yucca Mountain. Seepage calculations are conducted by (1) defining a heterogeneous drift-scale permeability model with field data, (2) selecting calibrated parameters associated with the Tptpmn and Tptpll units, and (3) simulating seepage, based on detailed degraded-drift profiles obtained from a separate rock mechanics engineering analysis. The simulation results indicate (1) that the seepage threshold (i.e., the percolation flux at which seepage first occurs) is not significantly changed by drift degradation and (2) the degradation-induced increase in seepage above the threshold is influenced probably more by the shape of the cavity created by rockfall than by rockfall volume.

The analysis of infiltration rates measured at both sites showed three temporal scales of infiltration rate: (1) a macro-scale trend of overall decreasing flow, (2) a meso-scale trend of fast and slow motion exhibiting three-stage variations of the flow rate (decreasing, increasing, and [again] decreasing flow rate, as observed in soils in the presence of entrapped air), and (3) micro-scale (high frequency) fluctuations. Infiltration tests in the nonwelded unit at Alcove 4 indicate that this unit may effectively dampen episodic fast infiltration events; however, well-known Kostyakov, Horton, and Philip equations do not satisfactorily describe the observed trends of the infiltration rate. Instead, a Weibull distribution model can most accurately describe experimentally determined time trends of the infiltration rate. Infiltration tests in highly permeable, fractured, welded tuff at Alcove 6 indicate that the infiltration rate exhibits pulsation, which may have been caused by multiple threshold effects and water-air redistribution between fractures and matrix. The empirical relationships between the extrinsic seepage from fractures, matrix imbibition, and gravity drainage versus the infiltration rate, as well as scaling and self-similarity for the leading edge of the water front are the hallmark of the nonlinear dynamic processes in water flow under episodic infiltration through fractured tuff. Based on the analysis of experimental data, we propose a conceptual model of a dynamic fracture flow and fracture-matrix interaction in fractured tuff, incorporating the time-dependent processes of water redistribution in the fracture-matrix system.

These studies are based on two- and three-dimensional (2-D and 3-D) numerical models using site-specific parameters. The 2-D and 3-D models use high-resolution spatial discretization to explicitly include effects of discrete fractures with stochastically developed fracture permeabilities and a continuum approach. The permeability field is generated based on air permeability measurements at various scales. For most of the cases considered, uniform infiltration with different average rates (1-500 mm/year) is prescribed at the top of the model, while variability in outflow at the bottom of the model is used to evaluate the degree of flow focusing. In addition, scenarios involving nonuniform infiltration at the top boundary, different permeability correlation lengths and different flow-allocation schemes were analyzed. The modeling results obtained from all of the cases showed a remarkably similar flow-focusing pattern at the repository horizon. Furthermore, tracer transport simulation results also revealed additional features of focused flow and transport through the fracture network.

The model considers the flow of water, gas, and heat, plus reactions between minerals, CO (sub 2) gas, and aqueous species, and porosity-permeability-capillary pressure coupling for a dual permeability (fractures and matrix) medium. Two possible operating temperature modes are investigated: a "high-temperature" case with temperatures exceeding the boiling point of water for several hundred years, and a "low-temperature" case with temperatures remaining below boiling for the entire life of the repository. In both cases, possible seepage waters are characterized by dilute to moderate salinities and mildly alkaline pH values. These trends in fluid composition and mineral alteration are controlled by various coupled mechanisms. For example, upon heating and boiling, CO (sub 2) exsolution from pore waters raises pH and causes calcite precipitation. In condensation zones, this CO (sub 2) redissolves, resulting in a decrease in pH that causes calcite dissolution and enhances feldspar alteration to clays. Heat also enhances dissolution of wall rock minerals leading to elevated silica concentrations. Amorphous silica precipitates through evaporative concentration caused by boiling in the high-temperature case, but does not precipitate in the low-temperature case. Some alteration of feldspars to clays and zeolites is predicted in the high-temperature case. In both cases, calcite precipitates when percolating waters are heated near the drift. The predicted porosity decrease around drifts in the high-temperature case (several percent of the fracture volume) is larger by at least one order of magnitude than in the low temperature case. Although there are important differences between the two investigated temperature modes in the predicted evolution of fluid compositions and mineral alteration around drifts, these differences are largely within to the model uncertainty and the variability of water compositions 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.

We designed and conducted a flow visualization experiment to investigate capillary barrier performance in this context. A two-dimensional, thin slab, test system replicated the physical emplacement drift to one-quarter scale (1.4-m diameter) and included the simulated drift wall, waste canister, pedestal, capillary barrier backfill, and host-rock fracture system. Water was supplied at the top of the simulated drift and allowed to discharge by way of wicks located along the left wall of the cell (simulated fractures) or by a gravity drain at the bottom of the right side (simulated impermeable rock with floor drain). Photographs captured the migration of water and a blue dye tracer within the system, analytical balances measured the mass balance of water, while tensiometers measured the capillary pressure at numerous locations. Of particular concern to this test was the drainage of the capillary barrier, which terminates against the drift wall. We found that while the simulated fractures (left side) and drain (right side) each influenced the performance of the capillary barrier at early time, they had little differential affect at later times. Also of concern was the small disparity in capillary properties between the fine and coarse layer (limited by the need of a fine-grained material that would not filter into the coarse layer under dry conditions). While the capillary barrier was able to divert the majority of flow toward the edges of the system and away from the simulated waste canister, the barrier did not preclude flow in the coarse layer, which was noted to be visually wet next to the waste canister on day 92 and was continuing to take on water at termination on day 112.

Various models for analyzing natural convection have been employed. The equivalent porous medium approach using Darcy's law has been used in many YMP applications. However, this approach has questionable fidelity, especially for turbulent flow conditions. Computational fluid dynamics (CFD), which is based on the fundamental Navier-Stokes equations, is currently being evaluated as a technique to calculate thermally induced natural convection in YMP. Data-model comparisons for turbulent flow conditions show good agreement of CFD predictions with existing experiments including YMP-specific data.

Systematic measurements of calcite and opal coatings in the Exploratory Studies Facility (ESF) tunnel at the proposed repository horizon are used to estimate the volume of calcite at each site of calcite and/or opal deposition. By estimating the volume of water required to precipitate the measured volumes of calcite in the unsaturated zone, seepage rates of 0.005 to 5 liters/year (l/year) are calculated at the median and 95th percentile of the measured volumes, respectively. These seepage rates are at the low end of the range of seepage rates from recent performance assessment (PA) calculations, confirming the conservative nature of the performance assessment. However, the distribution of the calcite and opal coatings indicate that a much larger fraction of the potential waste packages would be contacted by this seepage than is calculated in the performance assessment.

The lithophysal rock is described as a tri-continuum medium, consisting of fractures, rock matrices, and cavities. In the conceptual model, fractures have homogeneous properties throughout and interact with rock matrices and cavities that have different permeabilities and porosities. Global flow occurs through the fracture network only, while rock matrices and cavities contain the majority of fluid storage and provide fluid drainage to the fractures. Interporosity flows between the triple media are described using a pseudosteady-state concept and the system is characterized by interporosity transmissivity ratios and storativity ratio of each continuum. Pressure behavior is analyzed by examining the pressure drawdown curves, the derivative plots, and the effects of the characteristic parameters. Typical pressure responses from fractures, matrices, and cavities are represented by three semilog straight lines; the transitions by two troughs below the stabilization lines in the derivative plots. The analytical solution to the proposed model is further verified using a numerical simulation. The analytical model has also been applied to a published field-buildup well test and is able to match the pressure buildup data.

Flow modeling and field testing have shown that not all flow encountering a drift will seep into the drift. The underlying reason for the diversion of unsaturated flow around a drift is that capillary forces in the fractures and matrix prevent water entry into the drift unless the capillary pressure in the rock decreases sufficiently to allow for gravity forces to overcome the capillary barrier. As a result of the capillary barrier effect, flow tends to be diverted around the drift, affecting the flow pattern beneath the drift. For some distance beneath the drift, water saturation and flux are reduced. This drift shadow zone is much more pronounced in the fractures than in the matrix due to dominance of gravity over capillary forces in the fractures. Moving downward, away from the drift, the shadow zone asymptotically re-equilibrates to the undisturbed flow conditions due to capillary forces. The behavior of radionuclide transport in this zone of reduced flow is investigated here because this will affect the amount of time required for radionuclides to penetrate the unsaturated zone. The delay of radionuclide movement in the geosphere is one aspect of the potential repository system that could limit public exposure to radioactive waste. The behavior of flow and transport is calculated using a two-dimensional, drift-scale dual-permeability model extending to nine drift diameters below the potential waste emplacement drift. The flow model is first compared with an analytical model for a single continuum. Then, the dual-continuum flow model is investigated with respect to drift-scale and mountain-scale property sets. Transport calculations are performed for a wide range of flow conditions and for different aqueous radionuclides and colloids. Findings indicate that transport times for dissolved or colloidal material released from a drift without seepage are several orders of magnitude longer than if the releases occurred in the undisturbed flow field. Furthermore, the calculations indicate that the transport rate for radionuclides released in the drift shadow is relatively insensitive to flow rates in the fractures, but is sensitive to the flow rate in the matrix.

A multilayer, one-dimensional analytical solution is presented for determining percolation flux from temperature data. Case studies have shown that the analytical solution agrees very well with results from the numerical code, TOUGH2. The results of the analysis yield percolation fluxes in the range from 0 to 20 mm/year for most of the deep boreholes. This range is in good agreement with the results of infiltration studies at Yucca Mountain. Percolation flux for the shallower boreholes, however, cannot be accurately determined from temperature data alone because large gas flow in the shallow system alters the temperature profiles. Percolation-flux estimates for boreholes located near or intersecting major faults are significantly higher than those for other boreholes. These estimates may be affected by gas flow in the faults.

The Drift Scale Test (DST), intended for acquiring such an understanding of these processes, has generated a huge volume of temperature and moisture redistribution data. Sophisticated thermal-hydrological (TH) conceptual models have yielded a good fit between simulation results and those measured data. However, some uncertainties in understanding the TH processes associated with the DST still exist. This paper evaluates these uncertainties and provides quantitative estimates of the range of these uncertainties. Of particular interest for the DST are the uncertainties resulting from the unmonitored loss of vapor through an open bulkhead of the test. There was concern that the outcome from the test might have been significantly altered by these losses. Using alternative conceptual models, we illustrate that predicted mean temperatures from the DST are within 1 degrees C of the measured mean temperatures through the first 2 years of heating. The simulated spatial and temporal evolution of drying and condensation fronts is found to be qualitatively consistent with measured saturation data. Energy and mass balance computation shows that no more than 13% of the input energy is lost because of vapor leaving the test domain through the bulkhead. The change in average saturation in fractures is also relatively small. For a hypothetical situation in which no vapor is allowed to exit through the bulkhead, the simulated average fracture saturation is not qualitatively different enough to be discerned by measured moisture redistribution data. This leads us to conclude that the DST, despite the uncertainties associated with open field testing, has provided an excellent understanding of the TH processes.

The abundance of fractures and the spatial variability in their hydraulic properties, along with the heterogeneity within lithologic formations, make evaluation of unsaturated processes occurring within the potential repository horizon complex. Fracture mapping and field testing show that fractures are well connected, yet considerable variation is seen within and between units comprising the potential repository horizon with regard to fracture trace length, spacing, permeability, and capillarity. These variations have important implications for the distribution and movement of water and solutes through the unsaturated zone. Numerical models designed to assess such phenomena as unsaturated flow, transport, and coupled thermal-hydrological processes each require their own conceptual model for fracture networks, in order to identify the subset of all fractures that is relevant to the particular study. We evaluate several process-dependent conceptual models for fractures and identify the relevant fracture subsets related to these processes.

The SAR data collection methods evaluated are: infrared-stimulated luminescence (IRSL), post-IR blue-OSL, IRSL with TL annealing cycles on polymineral fine-grains, and blue-OSL on quartz fine sand. A single-grain laser luminescence (SGLL) procedure for quartz sand is also evaluated. Age estimates obtained from these methods are compared with radiocarbon, soil PDI (profile development index), and IRSL multi-aliquot additive dose (MAAD) age constraints. Our results indicate that the modal D (sub e) of quartz sand SGLL dose distributions yield ages that are consistent with radiocarbon and PDI age constraints for the tuff derived sediments in this investigation and appears to be the most promising method for studies in this area. Additionally, two fine-grained polymineral methods, IRSL SAR and traditional IRSL MAAD, produced ages that were generally in agreement with the SGLL ages and with available (super 14) C and PDI age constraints. At the present stage of research, we advocate using quartz sand SGLL in conjunction with IRSL SAR or even IRSL MAAD for polymineral fine-grains to provide the most robust and reliable luminescence age data sets for tuff-derived sediments.

This renders the unsaturated flow equations stochastic. Determining statistics of pressure head statistics, psi , is nontrivial, since the Richards equation is highly nonlinear. The prevalent approach is to linearize relative hydraulic conductivity, K sub(r)( psi ), around the ensemble mean pressure head, , which often leads to significant errors. Recently, an approach has been proposed to avoid such a linearization for the Gardner model, K sub(r)=exp( alpha psi ), with the soil parameter alpha being a random variable. We generalize this approach by allowing alpha to be a random field. This is achieved by means of a partial mean-field approximation with respect to alpha (x). Using two-dimensional infiltration into a heterogeneous soil with uncertain hydraulic parameters as an example, we demonstrate that our predictions of the mean pressure head and its variance remain accurate for moderately variable alpha s. The robustness of our solutions increases with the correlation length of alpha .

AN - 73251764; 12714298 AB - Retardation of certain radionuclides due to sorption to zeolitic minerals is considered one of the major barriers to contaminant transport in the unsaturated zone of Yucca Mountain. However, zeolitically altered areas are lower in permeability than unaltered regions, which raises the possibility that contaminants might bypass the sorptive zeolites. The relationship between hydrologic and chemical properties must be understood to predict the transport of radionuclides through zeolitically altered areas. In this study, we incorporate mineralogical information into an unsaturated zone transport model using geostatistical techniques to correlate zeolitic abundance to hydrologic and chemical properties. Geostatistical methods are used to develop variograms, kriging maps, and conditional simulations of zeolitic abundance. We then investigate, using flow and transport modeling on a heterogeneous field, the relationship between percent zeolitic alteration, permeability changes due to alteration, sorption due to alteration, and their overall effect on radionuclide transport. We compare these geostatistical simulations to a simplified threshold method in which each spatial location in the model is assigned either zeolitic or vitric properties based on the zeolitic abundance at that location. A key conclusion is that retardation due to sorption predicted by using the continuous distribution is larger than the retardation predicted by the threshold method. The reason for larger retardation when using the continuous distribution is a small but significant sorption at locations with low zeolitic abundance. If, for practical reasons, models with homogeneous properties within each layer are used, we recommend setting nonzero K(d)s in the vitric tuffs to mimic the more rigorous continuous distribution simulations. Regions with high zeolitic abundance may not be as effective in retarding radionuclides such as Neptunium since these rocks are lower in permeability and contaminants can only enter these regions through molecular diffusion.

AN - 73235375; 12714316 AB - A weakly sorbing cation, lithium, will be used as a reactive tracer in upcoming field tracer tests in the saturated alluvium south of Yucca Mountain, Nevada. One objective of the field tests is to determine how well field-scale reactive transport can be predicted using transport parameters derived from laboratory experiments. This paper describes several laboratory lithium batch sorption and column transport experiments that were conducted using ground water and alluvium obtained from the site of the planned field tests. In the batch experiments, isotherms were determined over 2.5 orders of magnitude of lithium concentrations, corresponding to the range expected in the field tests. In addition to measuring equilibrium lithium concentrations, concentrations of other cations, namely Na(+), K(+), and Ca(2+), were measured in the batch tests to determine Li(+)-exchangeable equilibria. This information was used in conjunction with alluvium cation exchange capacity measurements to parameterize a three-component cation-exchange model (EQUIL) that describes lithium sorption in the alluvium system. This model was then applied to interpret the transport behavior of lithium ion in saturated alluvium column tests conducted at three different lithium bromide injection concentrations. The concentrations were selected such that lithium ion either dominated, accounted for a little over half, or accounted for only a small fraction of the total cation equivalents in the injection solution. Although tracer breakthrough curves differed significantly under each of these conditions, with highly asymmetric responses occurring at the highest injection concentrations, the three-component cation-exchange model reproduced the observed transport behavior of lithium and the other cations in each case with a similar set of model parameters. In contrast, a linear K(d)-type sorption model could only match the lithium responses at the lowest injection concentration. The three-component model will be used to interpret the field tests, with the expectation that it will help refine estimates of effective flow porosity, particularly if the lithium response curves are asymmetric.

AN - 73235323; 12714313 AB - Two cross-hole tracer tests involving the simultaneous injection of two nonsorbing solute tracers with different diffusion coefficients (bromide and pentafluorobenzoate) and one weakly sorbing solute tracer (lithium ion) were conducted in two different intervals at the C-wells complex near the site of a potential high-level nuclear waste repository at Yucca Mountain, NV. The tests were conducted to (1) test a conceptual radionuclide transport model for saturated, fractured tuffs near Yucca Mountain and (2) obtain transport parameter estimates for predictive modeling of radionuclide transport. The differences between the responses of the two nonsorbing tracers and the sorbing tracer (when normalized to injection masses) were consistent with a dual-porosity transport system in which matrix diffusion was occurring. The concentration attenuation of the sorbing tracer relative to the nonsorbing tracers suggested that diffusion occurred primarily into matrix pores, not simply into stagnant water within the fractures. The K(d) values deduced from the lithium responses were generally larger than K(d) values measured in laboratory batch sorption tests using crushed C-wells cores. This result supports the use of laboratory-derived K(d) values for predicting sorbing species transport at the site, as the laboratory K(d) values would result in underprediction of sorption and hence conservative transport predictions. The tracer tests also provided estimates of effective flow porosity and longitudinal dispersivity at the site. The tests clearly demonstrated the advantages of using multiple tracers of different physical and chemical characteristics to distinguish between alternative conceptual transport models and to obtain transport parameter estimates that are better constrained than can be obtained using only a single tracer or using multiple nonsorbing tracers without a sorbing tracer.

AN - 73213690; 12714297 AB - A numerical model was used to simulate the flow and transport processes at the Busted Butte Field Test Site for the purpose of quantifying the effects of hydrogeologic conditions beneath the potential Yucca Mountain repository horizon. In situ experiments were conducted on a 10 x 10 x 7 m block comprising a layered Topopah Springs/Calico Hills formation with two imbedded faults. Tracer solution was continuously injected in eight parallel boreholes arranged on two horizontal planes. Twelve collection boreholes were emplaced perpendicular to the injection holes and were both horizontal and inclined. Solution samples were collected regularly using a sampling assembly consisting of an inverted membrane and sorbing-paper sampling pads. Comparisons between measurements and predictions show that, except for the occasional drops of concentrations observed in the field, the current model is able to capture the general characteristics of the system with varying levels of agreement using laboratory-measured mean hydraulic properties. Simulation results and field observations revealed a capillary-driven flow in the system. Good quantitative agreement is generally observed for near-field boreholes, however, this agreement deteriorates and the simulated solute concentration is underestimated at boreholes farther away from the injection points. Increasing the spatial resolution of the simulation improves the model predictions only to a limited extent. Scaling issues may need to be considered to describe flow and transport events, as the travel distance becomes large.

We improved the precision of microseismic event locations four-fold over initial locations by manually repicking the traveltimes in a spatial sequence, allowing us to visually correlate waveforms of adjacent sources. The new locations show vertical containment within individual, targeted sands, suggesting little or no hydraulic communication between the discrete perforation intervals simultaneously treated within an 80-m section. Treatment (i.e., fracture-zone) lengths inferred from event locations are about 200 m greater at the shallow perforation intervals than at the deeper intervals. The highest quality locations indicate fracture-zone widths as narrow as 6 m. Similarity of adjacent-source waveforms, along with systematic changes of phase amplitude ratios and polarities, indicate fairly uniform source mechanisms (fracture plane orientation and sense of slip) over the treatment length. Composite focal mechanisms indicate both left- and right-lateral strike-slip faulting along near-vertical fractures that strike sub-parallel to maximum horizontal stress. The focal mechanisms and event locations are consistent with activation of the reservoir's prevalent natural fractures, fractures that are isolated within individual sands and trend subparallel to the expected hydraulic fracture orientation (maximum horizontal stress direction). Shear activation of these fractures indicates a stronger correlation of induced seismicity with low-impedance flow paths than is normally found or assumed during injection stimulation.

The advantages of a Bayesian approach to tomography are that large-scale and high-resolution tomographic models available from other well-accepted studies can be used as prior background models. The resulting refined tomographic model will blend into these prior background models. Moreover, the uncertainties are well established in a Bayesian framework. We assume a general linear Gaussian (least squares) model, where the covariance matrix is partitioned into data and prior model components. Uncertain data are naturally down weighted and model components with small errors will be subject to little change. Amplitude tomography provides only an approximation to the propagation effects a seismic wave may experience. For example, phase blockage can occur over relatively short distances in the absence of any anelastic effects. Station-centric kriged amplitude correction surfaces on top of the tomographic models may assist in identifying blocked paths. Because a signal-to-noise criterion is used to select amplitudes for the inversion, the data are left-censored and the resulting Q (sub 0) models will be biased high. We examine the utility of a maximum-likelihood data augmentation method to the left-censored data problem (Schafer, 1997). In this case, we can only measure an upper bound to measured amplitudes on the basis of prephase noise. Data augmentation is used to impute the missing data values with their conditional expectation based on the relationship of amplitudes with other completely observed variables. We have initially chosen a bivariate Gaussian model for filling in missing amplitudes based on the relationship between amplitude and prephase noise. We apply the technique to eastern Asia for Lg signals at 1 Hz using data from 1651 earthquakes recorded at 12 stations. Tomographic patterns correlate well with those expected from geophysical considerations (e.g., high attenuation in Tibet and low attenuation up into the stable regions of Kazakhstan). Many of the large cratonic basins surrounding the Tibet Plateau (e.g., Tarim, Junggar) show reduced attenuation consistent with the hypothesis that they represent regions of stronger lithosphere. Data augmentation tends to increase attenuation in Tibet (particularly western Tibet) and the cratonic basins to the North of but not to the East of Tibet. In addition, the resulting models are much smoother than models that do not account for censoring.

We use a fourth-order finite-difference staggered-grid method with the coarse-grained frequency-independent anelastic scheme of Day and Bradley (2001) and a variable slip distribution from kinematic inversion for the Northridge earthquake. We find that the near-surface material with S-wave velocity (V (sub s) ) as low as 500 m/sec significantly affects the long-period peak ground velocities, compared with simulations in which the S-wave velocity is constrained to 1 km/sec and greater. Anelastic attenuation also has a strong effect on ground-motion amplitudes, reducing the predicted peak velocity by a factor of up to 2.5, relative to lossless simulations. Our preferred Q model is Qs/Vs = 0.02 (V (sub s) in meters per second) for V (sub s) less than 1-2 km/sec, and much larger Q (sub s) /V (sub s) (0.1, V (sub s) in meters per second) for layers with higher velocities. The simple model reduces the standard deviation of the residuals between synthetic and observed natural log of peak velocity from 1.13 to 0.26, relative to simulations for the lossless case. The anelastic losses have their largest effect on short-period surface waves propagating in the Los Angeles basin, which are principally sensitive to Q (sub s) in the low-velocity, near-surface sediments of the basin. The low-frequency ground motion simulated here is relatively insensitive to Q (sub p) , as well as to the values of Q (sub s) at depths greater than roughly that of the 2-km/sec S-wave velocity isosurface.

The Holocene Caldera is 10 km in diameter and 1 km deep. There were several post-caldera eruptions, the youngest in 1931. Samples were collected from both pre-caldera and post-caldera (including the 1931 flow) flows, domes, and plugs within the caldera. Three samples collected from the caldera walls or floor are tholeiitic basaltic andesites and andesites (SiO (sub 2) = 53.5 - 61.2%; Al (sub 2) O (sub 3) = 15.8 - 17.1%, CaO = 5.6 - 8.5%; MgO = 4.2 - 2.4%; K (sub 2) O = 1.6=2.0%) and represent pre-caldera lavas. They contain plagioclase, augite, + or - orthopyroxene, + or - olivine. Four samples are post-caldera calc-alkaline two-pyroxene dacites (SiO (sub 2) = 64.7 - 67.3%; Al (sub 2) O (sub 3) = 15.3 - 15.7%, CaO = 3.6 - 4.2%; MgO = 1.3 - 1.6%; K (sub 2) O = 2.3 - 2.4%). Pre-caldera lavas have lower SiO (sub 2) and K (sub 2) O and higher Al (sub 2) O (sub 3) and CaO than post-caldera lavas. One sample is a granitic xenolith from a pre-caldera flow exposed in the caldera wall. Mineralogically, the granitic xenolith contains stressed quartz, orthoclase, plagioclase, augite, biotite, and epidote. Pre-caldera and post-caldera samples fall on trends of different slopes on TiO (sub 2) -SiO (sub 2) , MnO-SiO (sub 2) , and Al (sub 2) O (sub 3) -SiO (sub 2) plots. This suggests different differentiation mechanisms during pre- and post-caldera building stages, as observed by Nye et al. (1995: GSA Cordilleran Abstracts, p. 69). The granitic xenolith falls off major and trace element trends, with significantly higher Nb (xenolith = 16 ppm; lavas = 2-6 ppm) and lower Zr (xenolith = 111 ppm; lavas = 157-222 ppm) and Y (xenolith = 14 ppm; lavas = 38-43 ppm) than Aniakchak lavas. These differences, the stressed quartz, and the presence of hydrothermal epidote together suggest that the xenolith is a sample of pre-Aniakchak plutonic crust. The continental volcanoes in the Aleutian region (including Aniakchak) contain higher K (sub 2) O, Na (sub 2) O, and SiO (sub 2) , and lower CaO, MgO, and FeO than the oceanic volcanoes. In addition, the continental volcanoes are calc-alkaline, in contrast to the tholeiitic nature of the oceanic volcanoes. Aniakchak is unusual because it erupted both tholeiitic and calc-alkaline lavas.

These studies are required because six small-volume alkali-basalt volcanoes have erupted within 20 km of Yucca Mountain during the Quaternary. Probabilistic estimates of the hazard to the repository depend on the recurrence rate and spatial distribution of past volcanism in the region. Most estimates of the hazard fall within the range of 10 (super -7) to 10 (super -9) disruptions per year, including the results of an expert elicitation sponsored by the U.S. Department of Energy in 1995-1996. Uncertainty in the disruption estimate is dominated by uncertainty in the volcanic recurrence rate, which generally ranges from 10 (super -5) to 10 (super -6) volcanic events per year (recurrence intervals of 10 (super 5) to 10 (super 6) years). Reasons for uncertainties in estimates of the recurrence rate include (1) differing interpretations of what constitutes a volcanic event (e.g., each individual volcano represents a volcanic event versus volcano alignments that may represent single or multiple events), (2) limited understanding of magmatic or tectonic processes that could impact recurrence rates, and (3) uncertainty in the number of volcanoes buried in alluvial-filled basins surrounding Yucca Mountain. The potential number of buried volcanoes is primarily interpreted from air and ground magnetic surveys. Approximately 20 magnetic anomalies are currently interpreted as shallowly (<250 meters) buried basalt. Drilling indicates the presence of at least four buried basaltic bodies; the youngest has been dated at 3.8 m.y. using the (super 40) Ar/ (super 39) Ar method. Faulted Miocene tuffs with strong magnetic signals produce complex magnetic anomalies and underlie a significant proportion of alluvial-filled basins, complicating interpretation of magnetic data used to estimate the number of buried volcanoes. The density of possible buried volcanoes present in basins underlain by bedrock of relatively low magnetic intensity can be reliably determined, and if representative of the larger region, indicates that the number of buried volcanoes inferred from magnetic data has not been significantly underestimated.

This study is to determine the effects on the critical population from erupted tephra carried along or through the Fortymile Wash drainage system and into the Amargosa Valley, which is main drainage for the eastern slope of Yucca Mountain. The critical population lives at a distance of approx 20 km from the repository, on the alluvial fan of Fortymile Wash. Our study evaluates ash redistribution through this drainage system in order to determine the impact to the critical population. We will determine the nature of the ash redistribution area and how the ash is diluted through the drainage system. We purpose to calculate the volume of material that has been deposited within the past 50 years using Cesium-137, a bomb produced tracer, to determine the erosional and depositional patterns around Yucca Mountain. Initial results will be presented. This study covers an area of >1500 square km (significantly larger than previous Cesium-137 studies). Because of the proximity to the location of nuclear air tests, the background (reference) Cesium-137 values are determined. The Lathrop Wells volcanic cone, located 12 km south of Yucca Mountain, erupted 70,000 years ago and produced an extensive tephra sheet. This tephra sheet has been studied as an analog to a tephra apron resulting from an eruption through the repository to determine extent of tephra dilution (by non-tephra sediment) in drainages west and south of the cone. Samples have been collected at intervals along the first order ash filled drainages on the tephra sheet and along the second and third order drainages into which the tephra is carried. A transect will be established along which ash is diluted from its source over a distance of > 2km. The values obtained from the ash dilution study, applying the scaling factor for the Fortymile Wash system, will be used to calculate the amount of contaminated ash that would reach the critical population and impact the calculation of the dose. Additional analog dilution studies have been done at Sunset Crater, AZ and in the Cima volcanic field, CA.

Effective performance of such a repository would rely on a number of natural and engineered barriers to isolate radioactive waste from the accessible environment. Groundwater beneath Yucca Mountain is the primary medium through which most radionuclides might move away from the potential repository. The saturated zone (SZ) system is expected to act as a natural barrier to this possible movement of radionuclides both by delaying their transport and by reducing their concentration before they reach the accessible environment. Information obtained from Yucca Mountain Site Characterization Project activities is used to estimate groundwater flow rates through the site-scale SZ flow and transport model area and to constrain general conceptual models of groundwater flow in the site-scale area. The site-scale conceptual model is a synthesis of what is known about flow and transport processes at the scale required for total system performance assessment of the site. This knowledge builds on and is consistent with knowledge that has accumulated at the regional scale but is more detailed because more data are available at the site-scale level. The mathematical basis of the site-scale model and the associated numerical approaches are designed to assist in quantifying the uncertainty in the permeability of rocks in the geologic framework model and to represent accurately the flow and transport processes included in the site-scale conceptual model. Confidence in the results of the mathematical model was obtained by comparing calculated to observed hydraulic heads, estimated to measured permeabilities, and lateral flow rates calculated by the site-scale model to those calculated by the regional-scale flow model. In addition, it was confirmed that the flow paths leaving the region of the potential repository are consistent with those inferred from gradients of measured head and those independently inferred from water-chemistry data. The general approach of the site-scale SZ flow and transport model analysis is to calculate unit breakthrough curves for radionuclides at the interface between the SZ and the biosphere using the three-dimensional site-scale SZ flow and transport model. Uncertainties are explicitly incorporated into the site-scale SZ flow and transport abstractions through key parameters and conceptual models.

At several locations, the measured values of super(36)Cl/Cl ratios for salts leached from rock samples are high enough to provide strong evidence that at least a small component of bomb- pulse super(36)Cl, fallout from atmospheric testing of nuclear devices in the 1950s and 1960s, was measured, implying that some fraction of the water traveled from the ground surface through 200-300 m of unsaturated rock to the level of the ESF during the last 50 years. These data are analyzed here using a formal statistical approach based on log-linear models to evaluate alternative conceptual models for the distribution of such fast flow paths. The most significant determinant of the presence of bomb-pulse super(36)Cl in a sample from the welded Topopah Spring unit (TSw) is the structural setting from which the sample was collected. Our analysis generally supports the conceptual model that a fault that cuts through the nonwelded Paintbrush tuff unit (PTn) that overlies the TSw is required in order for bomb-pulse super(36)Cl to be transmitted to the sample depth in less than 50 years. Away from PTn-cutting faults, the ages of water samples at the ESF appear to be a strong function of the thickness of the nonwelded tuff between the ground surface and the ESF, due to slow matrix flow in that unit.

Earlier models in delineating capture zones assumed the medium to be homogeneous. Recently, stochastic approaches have been applied to studying capture zones in heterogeneous media. The Monte Carlo method is commonly used to infer the probability distribution of the resulting capture zones from multiple realizations of the aquifer of interest. In this study, we present a moment-equation-based approach to derive the time-dependent mean capture zones and their associated uncertainties. The flow statistics are obtained by solving the first two moments of flow, and the mean capture zones are determined by reversely tracking the nonreactive particles released at a small circle around each pumping well. The uncertainty associated with the mean capture zones is calculated based on the particle displacement covariance X sub(ij) for nonstationary flow fields. For comparison purposes, we also conducted Monte Carlo simulations. It has been found that our model results are in excellent agreement with Monte Carlo results.

In these experiments, multiple (10-100) strands of DNA with tetramethyl rhodamine labeled dUMP (TMR-dUMP) incorporated into the sequence were anchored in flow upstream of the detection region of an ultra sensitive flow cytometer. A dilute solution of Exonuclease I passed over the microspheres. When an exonuclease attached to a strand, processive digestion of that strand began. The liberated, labeled bases flowed through the detection region and were detected at high efficiency at the single-molecule level by laser-induced fluorescence. The digestion of a single strand of DNA by a single exonuclease was discernable in these experiments. This result demonstrates the feasibility of single-molecule DNA sequencing. In addition, these experiments point to a new and practical means of arriving at a consensus sequence by individually reading out identical sequences on multiple fragments.

The results are based on a numerical model of site-scale saturated zone beneath Yucca Mountain. This model is used for performance assessment predictions of radionuclide transport and to guide future data collection and modeling activities. The numerical model is calibrated by matching available water level measurements using parameter estimation techniques, along with more informal comparisons of the model to hydrologic and geochemical information. The model software (hydrologic simulation code FEHM and parameter estimation software PEST) and model setup allows for efficient calibration of multiple conceptual models. Until now, the Large Hydraulic Gradient has been simulated using a low-permeability, east-west oriented feature, even though direct evidence for this feature is lacking. In addition to this model, we investigate and calibrate three additional conceptual models of the Large Hydraulic Gradient, all of which are based on a presumed zone of hydrothermal chemical alteration north of Yucca Mountain. After examining the heads and permeabilities obtained from the calibrated models, we present particle pathways from the potential repository that record differences in the predicted groundwater flow regime. The results show that Large Hydraulic Gradient can be represented with the alternate conceptual models that include the hydrothermally altered zone. The predicted pathways are mildly sensitive to the choice of the conceptual model and more sensitive to the quality of calibration in the vicinity on the repository. These differences are most likely due to different degrees of fit of model to data, and do not represent important differences in hydrologic conditions for the different conceptual models.

This study uses a reaction path calculation to estimate tank supernatant compositions from historical tank inventory data. The Pitzer activity coefficient algorithm based on the computer code GMIN is combined with the reactive transport code FLOTRAN to carry out the simulations. An extended version of the GMIN database is used which includes Al and Si species. In order for the reaction path calculations to converge, a pseudo-kinetic approach employing a rate limiter for precipitation kinetics is introduced. The rate limiter enables calculations to be carried out with the reaction path approach which previously could only be accomplished using a Gibbs free energy minimization technique. Because the final equilibrium state is independent of the reaction path, the value used for the rate limiter does not affect the calculation for the tank supernatant composition. Three different tanks are considered: SX-108, SX-109 and SX-115, with supernatant compositions ranging from extremely to moderately concentrated. Results of the simulations indicate that sodium concentrations much higher than previously expected are possible for the SX-108 tank. This result has important implications for the migration of cesium released from the tank within the vadose zone. The mineral cancrinite was predicted to form in all three tanks consistent with recent experiments. The calculated supernatant pH ranged from 14 to 12.8 for the tanks considered and Eh was mildly reducing determined by the redox couple NO sub(3)-NO sub(2).

The goal of the effort was to produce a computational model that can be coupled to the project's calibrated 3D site-scale flow model so that the results of that effort could be incorporated directly into the Total System Performance Assessment (TSPA) analyses. The transport model simulates multiple species (typically 20 or more) with complex time-varying and spatially varying releases from the potential repository. Water-table rise, climate-change scenarios, and decay chains are additional features of the model. A cell-based particle-tracking method was employed that includes a dual-permeability formulation, advection, longitudinal dispersion, matrix diffusion, and colloid- facilitated transport. This paper examines the transport behavior of several key radionuclides through the unsaturated zone using the calibrated 3D unsaturated flow fields. Computational results illustrate the relative importance of fracture flow, matrix diffusion, and lateral diversion on the distribution of travel times from the simulated repository to the water table for various climatic conditions. Results also indicate rapid transport through fractures for a portion of the released mass. Further refinement of the model will address several issues, including conservatism in the transport model, the assignment of parameters in the flow and transport models, and the underlying assumptions used to support the conceptual models of flow and transport in the unsaturated zone at Yucca Mountain.

It is very challenging to obtain a complete or to interpret an incomplete tandem MS/MS spectrum from fragmentation of a weak peptide ion signal for sequence assignment. Here, we have developed an effective and high-throughput MALDI-TOF-based method for the identification of membrane and other low-abundance proteins with a simple, one-dimensional separation step. In this approach, several stable isotope-labeled amino acid precursors were selected to mass-tag, in parallel, the human proteome of human skin fibroblast cells in a residue-specific manner during in vivo cell culturing. These labeled residues can be recognized by their characteristic isotope patterns in MALDI-TOF MS spectra. The isotope pattern of particular peptides induced by the different labeled precursors provides information about their amino acid compositions. The specificity of peptide signals in a peptide mass mapping is thus greatly enhanced, resolving a high degree of mass degeneracy of proteolytic peptides derived from the complex human proteome. Further, false positive matches in database searching can be eliminated. More importantly, proteins can be accurately identified through a single peptide with its m/z value and partial amino acid composition. With the increased solubility of hydrophobic proteins in SDS, we have demonstrated that our approach is effective for the identification of membrane and low-abundant proteins with low sequence coverage and weak signal intensity, which are often difficult for obtaining informative fragment patterns in tandem MS/MS peptide sequencing analysis.

AN - 85269471; pmid-12689235 AB - We measure the defect density as a function of time at different temperatures in simulations of a two-dimensional system of interacting particles. Just above the solid to liquid transition temperature, the power spectrum of the defect fluctuations shows a 1/f signature, which crosses over to a white noise signature at higher temperatures. When 1/f noise is present, the 5-7 defects predominantly form stringlike structures, and the particle trajectories show a 1D correlated motion that follows the defect strings. At higher temperatures this heterogeneous motion is lost.

AN - 73068374; 12591946 AB - Using small-angle x-ray scattering, we have observed the cGMP-induced elongation of an active, cGMP-dependent, monomeric deletion mutant of cGMP-dependent protein kinase (Delta(1-52)PKG-I beta). On saturation with cGMP, the radius of gyration of Delta(1-52)PKG-I beta increases from 29.4 +/- 0.1 A to 40.1 +/- 0.7 A, and the maximum linear dimension increases from 90 A +/- 10% to 130 A +/- 10%. The elongation is due to a change in the interaction between structured regulatory (R) and catalytic (C) domains. A model of cGMP binding to Delta(1-52)PKG-I beta indicates that elongation of Delta(1-52)PKG-I beta requires binding of cGMP to the low-affinity binding site of the R domain. A comparison with cAMP-dependent protein kinase suggests that both elongation and activation require cGMP binding to both sites; cGMP binding to the low-affinity site therefore seems to be a necessary, but not sufficient, condition for both elongation and activation of Delta(1-52)PKG-I beta. We also predict that there is little or no cooperativity in cGMP binding to the two sites of Delta(1-52)PKG-I beta under the conditions used here. Results obtained by using the Delta(1-52)PKG-I beta monomer indicate that a previously observed elongation of PKG-I alpha is consistent with a pure change in the interaction between the R domain and the C domain, without alteration of the dimerization interaction. This study has revealed important features of molecular mechanisms in the biochemical network describing PKG-I beta activation by cGMP, yielding new insight into ligand activation of cyclic nucleotide-dependent protein kinases, a class of regulatory proteins that is key to many cellular processes.

AN - 85370554; pmid-12656366 AB - Thermoacoustic-Stirling hybrid engines and feedback pulse tube refrigerators can utilize jet pumps to suppress streaming that would otherwise cause large heat leaks and reduced efficiency. It is desirable to use jet pumps to suppress streaming because they do not introduce moving parts such as bellows or membranes. In most cases, this form of streaming suppression works reliably. However, in some cases, the streaming suppression has been found to be unstable. Using a simple model of the acoustics in the regenerators and jet pumps of these devices, a stability criterion is derived that predicts when jet pumps can reliably suppress streaming.

AN - 73250989; 12720278 AB - Superantigens secreted by the bacterial pathogen Staphyloccocus aureus are extremely potent toxins that overstimulate the host immune system by binding to the MHC class II and T cell receptors and activating a large population of T cells. Superantigen infection has been shown to be the causative agents in acute diseases, food poisoning and toxic shock syndrome, and in more chronic conditions such as inflammatory skin diseases. In addition to the toll on public health, S. aureus superantigens also represent a potential biothreat to our national security. To address these risks, a number of different therapeutic strategies have been developed that target different aspects of the pathogenic mechanism of S. aureus and superantigen infection. These therapies, which encompass strategies as diverse as production of neutralizing antibodies, inhibitory peptide/receptor design and blockage of superantigen gene transcription, are being tested for treatment of established S. aureus infections in pre- and post-exposure scenarios. In this review, we will describe these different strategies and their efficacies in inhibition of superantigen-induced effects in the host, and present the future outlook for successfully producing therapies for superantigen-based disease.

AN - 73219014; 12708699 AB - Lead arsenate was a commonly used insecticide during the first half of the 20th century, particularly in deciduous tree fruit orchards. Antimony is cotransported with As during the ore refining process and could occur as an impurity in commercial lead arsenate products. The total concentrations of As and Sb in eight soil samples collected from eight orchards located throughout central Washington State were analyzed by neutron activation analysis. Total soil Sb concentrations ranged between 0.4 and 1.5 mg kg(-1), while total soil As concentration ranged from 1 to 170 mg kg(-1). Total soil Sb and As concentrations were positively related. Total Pb and As concentrations in four of the soils were substantially higher than natural background, while the Sb to As concentration ratios in these soils were consistent with values measured in three lead arsenate insecticide products. These results confirm that Sb impurity is present in lead arsenate insecticide and has contributed to Sb enrichment of soils on which lead arsenate-treated plants were grown. Although higher than in uncontaminated soils from the same region, the Sb concentrations in the affected soils fall within the normal range observed worldwide and are substantially lower than values associated with impaired human or environmental health.

Refined water contents per unit cell (unit-cell formula: Ca (sub 4) Al (sub 8) Si (sub 16) O (sub 48) . nH (sub 2) O) ranged between 12.5 H (sub 2) O at 0.11 mbar PH (sub 2) O and 17.3 H (sub 2) O at 37.6 mbar. The occupancy of the two water sites hosting hydrogenbonded water molecules, W5 and W1, ranged from 13% to 100% and from 2% to 86%, respectively. During hydration of W5, between 0.11 and 5 mbar, the unit cell expanded continuously and reversibly from 1327 to 1348 Aa (super 3) . The unit-cell volume remained nearly constant between 5 and 28 mbar. The hydration/dehydration of W1 exhibited hysteresis; hydration occurred at approximately 29 mbar and dehydration at approximately 24 mbar. During hydration of W1 at approximately 29 mbar the unit cell expanded from 1351 to 1384 Aa (super 3) . Further hydration of W1 above 29 mbar resulted in gradual and reversible unit-cell expansion to 1386 Aa (super 3) at 37.6 mbar. Hydration/dehydration of W5 is a continuous reaction typical for zeolites. In contrast, the Hydration/dehydration of W1 at room temperature is discontinuous, as manifested by the presence of two laumontite phases during hydration and dehydration. Unit-cell parameters of the two coexisting laumontite phases observed under these conditions are consistent with a vacant W1 site and approximately 80%-occupied W1 site, respectively. Gradual unit-cell expansion above 29 mbar due to increased P (sub H2O) and increased occupancy of W1 indicate that hydration of the remaining 20% of the W1 site proceeds continuously.

The problem with volcanic ash is that its formation is poorly understood from the standpoint of eruption energetics. Because the source of explosive eruption energy should be the thermal energy of magma, and because an explosion requires rapid conversion of energy into a mechanical form, and because of the physical properties of magma thermal energy is dominantly released by conduction, the energy release on a short time scale (explosion) in volcanic processes has to be the result of a special mechanism, probably a positive feedback mechanism of fragmentation and heat exchange. In fact, the most explosive volcanic explosions are characterized by the most intensive fragmentation. In any fragmentation mechanism the generated particle sizes reflect the kinetic energy available (i.e. the fragmentation energy density). Consequently, fine ash (< or =64 mu m) provides information on fragmentation mechanisms that are the most energetic and related to the highest explosive energy release. In this letter we discuss mechanisms of formation of fine volcanic ash, using experimental results, theoretical considerations, and field observations. We focus on the potency of these mechanisms to explain fine ash produced by explosive volcanism. We conclude that quantitative analysis of fine ash particles is necessary to estimate the mechanical energy of volcanic explosions.

Previous quantitative modeling has shown that much has to be learned in order to better understand the implications of crustal recycling on mantle heterogeneity. Here, we present new model calculations incorporating recent constraints on subduction-zone processes and the composition of subducted sediments. Modeled compositions of the recycled oceanic crust vary widely as a function of the recycling age and composition of the oceanic crust. HIMU-type sources can only be created by recycling igneous oceanic crust if it has undergone substantial modification during subduction. Although the required modifications are qualitatively consistent with dehydration processes in subduction zones, the many uncertainties prevent a precise estimate of the isotopic composition of ancient recycled igneous crust. Inclusion of sediments increases the isotopic variability and although the resulting Sr and Nd isotopic signatures can be similar to enriched mantle (EM) signatures, the Pb isotopic composition of EM-type OIB is difficult to reconcile with the presence of sediment in their sources. The large variability of modeled compositions of the subducted crust suggests that if mantle heterogeneity is largely formed by crustal recycling, each OIB is likely to have a unique isotopic composition resulting from specific combinations of composition, age and subduction modification of the subducted crust. Given the variability of the recycled components, a small number of relatively well-defined enriched compositions can only be explained if either the subduction processing of oceanic crust is a far better defined process than observation would seem to indicate, or, the intramantle disaggregation and mixing of compositionally diverse recycled materials is surprisingly efficient.

Beneath stream channels, vertical temperature profiles vary over time in response to downward heat transport, which is generally controlled by conductive heat transport during dry periods, or by advective transport during channel infiltration. During periods of stream-channel infiltration, two relatively simple approaches are possible: a heat-pulse technique, or a heat and liquid-water transport simulation code. Focused percolation rates beneath stream channels are examined for perennial, seasonal, and ephemeral channels in central New Mexico, with estimated percolation rates ranging from 100 to 2100 mm d (super -1) . Deep within basin-fill and underlying mountainous terrain, vertical temperature gradients are dominated by the local geothermal gradient, which creates a profile with decreasing temperatures toward the surface. If simplifying assumptions are employed regarding stratigraphy and vapor fluxes, an analytical solution to the heat transport problem can be used to generate temperature profiles at specified percolation rates for comparison to the observed geothermal gradient. Comparisons to an observed temperature profile in the basin-fill sediments beneath Frenchman Flat, Nevada, yielded water fluxes near zero, with absolute values <10 mm yr (super -1) . For the deep vadose environment beneath Yucca Mountain, Nevada, the complexities of stratigraphy and vapor movement are incorporated into a more elaborate heat and water transport model to compare simulated and observed temperature profiles for a pair of deep boreholes. Best matches resulted in a percolation rate near zero for one borehole and 11 mm yr (super -1) for the second borehole.
