TY - JOUR T1 - Analysis of thermohydrologic behavior for above-boiling and below-boiling thermal-operating modes for a repository at Yucca Mountain. AN - 73229848; 12714304 AB - We report results from a multi-scale thermohydrologic modeling study for two alternative thermal-operating modes for the potential repository system recently analyzed by the Yucca Mountain Project. These include a Higher-Temperature Operating Mode (HTOM), which results in a localized boiling zone around each emplacement drift, and a Lower-Temperature Operating Mode (LTOM), which always maintains sub-boiling temperatures throughout the repository. The HTOM places all waste packages nearly end to end, making the lineal power density greater than in the LTOM. The lower lineal power density in the LTOM was achieved by placing some waste packages farther apart (which results in a larger repository footprint), and through an increased reliance on pre-closure ventilation to remove the waste-package-generated heat. We focus on temperature T and relative humidity RH at the waste-package and drift-wall surfaces, and on in-drift evaporation. In general, HTOM temperatures are greater than corresponding LTOM temperatures, exhibit similar spatial variability and have a stronger dependence on infiltration flux. The duration of RH reduction on waste packages is similar for the LTOM and HTOM. A major difference between the LTOM and HTOM is the lower waste-package temperature at any given value of waste-package RH for the LTOM. Waste-package temperatures in the LTOM, by design, remain below approximately 85 degrees C; the absence of RH reduction arising from host-rock dryout causes waste-package RH to remain above about 40%. The HTOM waste packages experience higher temperatures and correspondingly lower RH conditions as a result of RH reduction arising from host-rock dryout. For most of the repository area, the HTOM delays the potential onset of gravity-driven seepage compared to the LTOM (as indicated by the duration of boiling at the drift wall). Boiling conditions in the HTOM also delays the onset of capillary-driven seepage into the granular invert, causing the HTOM to have less evaporation in the invert during the first 800-1500 years than the LTOM; subsequent evaporation rates are higher in the HTOM, due to the higher power density.

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

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

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

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.

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

The 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.

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.

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

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

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

This study presents data collected from several investigations and indicates that B. anthracis virulence is associated with the clonality and virulence of plasmids pXO1 and pXO2. Guinea pigs vaccinated with Anthrax Vaccine Adsorbed were challenged with 20 B. anthracis isolates representative of worldwide genetic diversity. These same isolates were characterized with respect to plasmid copy number by using a novel method of quantitative PCR developed for rapid and efficient detection of B. anthracis from environmental samples. We found that the copy numbers for both pXO1 and pXO2 differed from those in previously published reports. By combining the data on survival, plasmid copy numbers, and clonality, we developed a model predicting virulence. This model was validated by using a randomly chosen set of 12 additional B. anthracis isolates. Results from this study will be helpful in future efforts to elucidate the basis for variation in the virulence of this important pathogen.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

N1 - Date revised - 2004-01-01 N1 - Last updated - 2012-06-07 ER - TY - JOUR T1 - Early human remains from Bano Nuevo-1 Cave, central Patagonian Andes, Chile AN - 51826132; 2004-053868 AB - The notable sparseness of human skeletal remains is a characteristic trait of early American prehistory, and, therefore, this aspect of the archaeological record is seldom considered in its discussion. In this context, the finding of remains from five individuals dated to the 9th millenium BP on the re-excavations at Bano Nuevo Cave (Andean Central Patagonia, Chile) is particularly interesting. They may not appear excessively old, but several radiocarbon dates (two of them done through AMS directly on the bone of one of the individuals) place them among the very few well-dated early human skeletons throughout the Americas. The small sample size militates against any interpretation of biological affiliation (to say nothing of population movements) and we can only affirm that these people belonged to a generalized "mongoloid stock", different from historically known Patagonian populations. After a brief presentation of the skeletal evidence and the bone dating methods, we evaluate the relevance of this context with respect to the sparse osteological record of humans in the Americas on the Pleistocene/Holocene transition.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

AN - 72804704; 12505291 AB - 2-Amino-1-methyl-6-phenylimidazo [4,5-b] pyridine (PhIP), a mutagen/carcinogen belonging to the class of heterocyclic amines (HCAs) found in cooked meats, is a mammary gland carcinogen in rats and has been implicated in the etiology of certain human cancers including breast cancer. To gain insight into the genomic alterations associated with PhIP-induced mammary gland carcinogenesis, we used comparative genomic hybridization (CGH) to examine chromosomal abnormalities in rat mammary carcinomas induced by PhIP, and for comparison, by DMBA (7, 12-dimethylbenz[a]anthracene), a potent experimental mammary carcinogen. There was a consistent and characteristic pattern of chromosome-region loss in PhIP-induced carcinomas that clearly distinguished them from carcinomas induced by DMBA.

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

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

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

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

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

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

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

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

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

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

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

This study examined the application of time-domain reflectometry (TDR) to measure solute transport in hillslopes. Three different plot designs were used to examine the transport of a conservative tracer in the first 50 cm of a moderately sloping soil. In the first plot, which was designed to examine spatial variability in vertical transport in a 1 times 2 m super(2) plot, a single probe per meter was found to adequately characterize vertical solute travel times. In addition, a dye and excavation study in this plot revealed lateral preferential flow in small macropores and a transport pattern where solute is focused vertically into preferential flow pathways. The bypass flow delivers solute deeper in the soil, where lateral flow occurs. The second plot, designed to capture both vertical and lateral flow, provided additional evidence confirming the flow patterns identified in the excavation of the first plot. The third plot was designed to examine lateral flow and once again preferential flow of the tracer was observed. In one instance rapid solute transport in this plot was estimated to occur in as little as 3% of the available pore space. Finally, it was demonstrated that the soil anisotropy, although partially responsible for lateral subsurface transport, may also homogenize the transport response across the hillslope by decreasing vertical solute spreading.

AN - 85360015; pmid-12398458 AB - Analysis of array data from acoustic scattering in a random medium with a small number of isolated targets is performed in order to image and, thereby, localize the spatial position of each target. Because the host medium has random fluctuations in wave speed, the background medium is itself a source of scattered energy. It is assumed, however, that the targets are sufficiently larger and/or more reflective than the background fluctuations so that a clear distinction can be made between targets and background scatterers. In numerical simulations nonreflective boundary conditions are used so as to isolate the effects of the host randomness from those of the spatial boundaries, which can then be treated in a separate analysis. It is shown that the key to successful imaging is finding statistically stable functionals of the data whose extreme values provide estimates of scatterer locations. The best ones are related to the eigenfunctions and eigenvalues of the array response matrix, just as one might expect from prior work on array data processing in complex scattering media having homogeneous backgrounds. The specific imaging functionals studied include matched-field processing and linear subspace methods, such as MUSIC (MUtiple SIgnal Classification). But statistical stability is not characteristic of the frequency domain, which is often the province of these methods. By transforming back into the time domain after first diagonalizing the array data in the frequency domain, one can take advantage of both the time-domain stability and the frequency-domain orthogonality of the relevant eigenfunctions.

AN - 72194335; 12387617 AB - A combination of computational methods, electrospray ionization mass spectroscopy (ESI-MS), and NMR spectroscopy has been used to identify novel small molecules that bind to two adjacent sites on the surface of the C fragment of tetanus toxin (TetC). One of these sites, Site-1, binds gangliosides present on the surface of motor neurons, while Site-2 is a highly conserved deep cleft in the structures of the tetanus (TeNT) and botulinum (BoNT) neurotoxins. ESI-MS was used to experimentally determine which of the top 11 computationally predicted Site-2 candidates bind to TetC. Each of the six molecules that tested positive was further screened, individually and as mixtures, for binding to TetC in aqueous solutions by NMR. A trNOESY competition assay was developed that used doxorubicin as a marker for Site-1 to provide insight into whether the predicted Site-2 ligands bound to a different site. Of the six predicted Site-2 ligands tested, only four were observed to bind. Naphthofluorescein-di-beta-galactopyranoside was insoluble under conditions compatible with TetC. Sarcosine-Arg-Gly-Asp-Ser-Pro did not appear to bind, but its binding affinity may have been outside the range detectable by the trNOESY experiment. Of the remaining four, three [3-(N-maleimidopropionyl)biocytin, lavendustin A, and Try-Glu-Try] bind in the same site, presumably the predicted Site-2. The fourth ligand, Ser-Gln-Asn-Tyr-Pro-Ile-Val, binds in a third site that differs from Site-1 or predicted Site-2. The results provide a rational, cost- and time-effective strategy for the selection of an optimal set of Site-1 binders and predicted Site-2 binders for use in synthesizing novel bidendate antidotes or detection reagents for clostridial neurotoxins, such as TeNT and BoNT.

AN - 72105479; 12236810 AB - Three somatic mutation assays were evaluated in men exposed to low-dose, whole-body, ionizing radiation. Blood samples were obtained between 1992 and 1999 from 625 Russian Chernobyl cleanup workers and 182 Russian controls. The assays were chromosome translocations in lymphocytes detected by FISH, hypoxanthine phosphoribosyltransferase (HPRT) mutant frequency in lymphocytes by cloning, and flow cytometic assay for glycophorin A (GPA) variant frequency of both deletion (N/Ø) and recombination (N/N) events detected in erythrocytes. Over 30 exposure and lifestyle covariates were available from questionnaires. Among the covariates evaluated, some increased (e.g. age, smoking) and others decreased (e.g. date of sample) biomarker responses at a magnitude comparable to Chernobyl exposure. When adjusted for covariates, exposure at Chernobyl was a statistically significant factor for translocation frequency (increase of 30%, 95% CI of 10%-53%, P = 0.002) and HPRT mutant frequency (increase of 41%, 95% CI of 19%-66%, P < 0.001), but not for either GPA assay. The estimated average dose for the cleanup workers based on the average increase in translocations was 9.5 cGy. Translocation analysis is the preferred biomarker for low-dose radiation dosimetry given its sensitivity, relatively few covariates, and dose-response data. Based on this estimated dose, the risk of exposure-related cancer is expected to be low.

This kind of resolution provides a novel opportunity to follow the dynamic flow behavior on the pore scale and to verify new theoretical and numerical modeling approaches.

We illustrate how stratigraphic ordering, sedimentological, and historical data can be used quantitatively in the process of estimating earthquake ages. Calibrated radiocarbon age distributions are used directly from layer dating through recurrence intervals and recurrence probability estimation. The method does not eliminate subjective judgements in event dating, but it does provide a means of systematically and objectively approaching the dating process. Date distributions for the most recent 14 events at Wrightwood are based on sample and contextual evidence in Fumal et al. (2002) and site context and slip history in Weldon et al. (2002). Pallett Creek event and dating descriptions are from published sources. For the five most recent events at Wrightwood, our results are consistent with previously published estimates, with generally comparable or narrower uncertainties. For Pallett Creek, our earthquake date estimates generally overlap with previous results but typically have broader uncertainties. Some event date estimates are very sensitive to details of data interpretation. The historical earthquake in 1857 ruptured the ground at both sites but is not constrained by radiocarbon data. Radiocarbon ages, a peat accumulation rates, and historical constraints at Pallett Creek for event X yield a date estimate in the earliest 1800s and preclude a date in the late 1600s. This event is almost certainly the historical 1812 earthquake, as previously concluded by Sieh et al. (1989). This earthquake also produced ground deformation at Wrightwood. All events at Pallett Creek, except for event T, about A.D. 1360, and possibly event I, about A.D. 960, have corresponding events at Wrightwood with some overlap in age ranges. Event T falls during a period of low sedimentation at Wrightwood when conditions were not favorable for recording earthquake evidence. Previously proposed correlations of Pallett Creek X with Wrightwood W3 in the 1690s and Pallett Creek event V with W5 around 1480 (Fumal et al., 1993) appear unlikely after our dating reevaluation. Apparent internal inconsistencies among event, layer, and dating relationships around events R and V identify them as candidates for further investigation at the site. Conditional probabilities of earthquake recurrence were estimated using Poisson, lognormal, and empirical models. The presence of 12 or 13 events at Wrightwood during the same interval that 10 events are reported at Pallett Creek is reflected in mean recurrence intervals of 105 and 135 years, respectively. Average Poisson model 30-year conditional probabilities are about 20% at Pallett Creek and 25% at Wrightwood. The lognormal model conditional probabilities are somewhat higher, about 25% for Pallett Creek and 34% for Wrightwood. Lognormal variance sigma (sub ln) estimates of 0.76 and 0.70, respectively, imply only weak time predictability. Conditional probabilities of 29% and 46%, respectively, were estimated for an empirical distribution derived from the data alone. Conditional probability uncertainties are dominated by the brevity of the event series; dating uncertainty contributes only secondarily. Wrightwood and Pallett Creek event chronologies both suggest variations in recurrence interval with time, hinting that some form of recurrence rate modulation may be at work, but formal testing shows that neither series is more ordered than might be produced by a Poisson process.

Calendar age estimates for these earthquakes are based on a chronological model that incorporates radiocarbon dates from 18 in situ burn layers and stratigraphic ordering constraints. These five earthquakes occurred in about A.D. 825 (770-890) (mean, 95% range), A.D. 982 (840-1150), A.D. 1231 (1170-1290), A.D. 1502 (1450-1555), and after a date in the range of A.D. 1520-1680. The most recent surface-rupturing earthquake at Thousand Palms is likely the same as the A.D. 1676+ or -35 event at Indio reported by Sieh and Williams (1990). Each of the past five earthquakes recorded on the San Andreas fault in the Coachella Valley strongly overlaps in time with an event at the Wrightwood paleoseismic site, about 120 km northwest of Thousand Palms Oasis. Correlation of events between these two sites suggests that at least the southernmost 200 km of the San Andreas fault zone may have ruptured in each earthquake. The average repeat time for surface-rupturing earthquakes on the San Andreas fault in the Coachella Valley is 215+ or -25 years, whereas the elapsed time since the most recent event is 326+ or -35 years. This suggests the southernmost San Andreas fault zone likely is very near failure. The Thousand Palms Oasis site is underlain by a series of six channels cut and filled since about A.D. 800 that cross the fault at high angles. A channel margin about 900 years old is offset right laterally 2.0+ or -0.5 m, indicating a slip rate of 4+ or -2 mm/yr. This slip rate is low relative to geodetic and other geologic slip rate estimates (26+ or -2 mm/yr and about 23-35 mm/yr, respectively) on the southernmost San Andreas fault zone, possibly because (1) the site is located in a small step-over in the fault trace and so the rate is not be representative of the Mission Creek fault, (2) slip is partitioned northward from the San Andreas fault and into the eastern California shear zone, and/or (3) slip is partitioned onto the Banning strand of the San Andreas fault zone.

In a network of 38 trenches and creek-bank exposures, we have exposed a composite section of interbedded debris flow deposits and thin peat layers more than 24 m thick; fluvial deposits occur along the northern margin of the site. The site is a 150-m-wide zone of deformation bounded on the surface by a main fault zone along the northwest margin and a secondary fault zone to the southwest. Evidence for most of the 14 earthquakes occurs along structures within both zones. We identify paleoearthquake horizons using in filled fissures, scarps, multiple rupture terminations, and widespread folding and tilting of beds. Ages of stratigraphic units and earthquakes are constrained by historic data and 72 (super 14) C ages, mostly from samples of peat and some from plant fibers, wood, pine cones, and charcoal. Comparison of the long, well-resolved paleoseimic record at Wrightwood with records at other sites along the fault indicates that rupture lengths of past earthquakes were at least 100 km long. Paleoseismic records at sites in the Coachella Valley suggest that each of the past five large earthquakes recorded there ruptured the fault at least as far northwest as Wrightwood. Comparisons with event chronologies at Pallett Creek and sites to the northwest suggests that approximately the same part of the fault that ruptured in 1857 may also have failed in the early to mid-sixteenth century and several other times during the past 1200 years. Records at Pallett Creek and Pitman Canyon suggest that, in addition to the 14 earthquakes we document, one and possibly two other large earthquakes ruptured the part of the fault including Wrightwood since about A.D. 500. These observations and elapsed times that are significantly longer than mean recurrence intervals at Wrightwood and sites to the southeast suggest that at least the southernmost 200 km of the San Andreas fault is near failure.

We conducted a paleoseismic investigation to better understand the Hayward fault's past earthquake behavior. The site is near the south end of Tyson's Lagoon, a sag pond formed in a right step of the fault in Fremont. Because the Hayward fault creeps at the surface, we identified paleoseismic events using features that we judge to be unique to ground ruptures or the result of strong ground motion, such as the presence of fault-scarp colluvial deposits and liquefaction. We correlate the most recent event evidence (E1) to the historical 1868 M 6.9 earthquake that caused liquefaction in the pond and recognize three additional paleoruptures since A.D. 1470+ or -110 yr. Event ages were estimated by chronological modeling, which incorporated historical and stratigraphic information and radiocarbon and pollen data. Modeled, mean age and 95-percentile ranges of the three earlier events are A.D. 1730 (1650-1790) yr (E2), A.D. 1630 (1530-1740) yr (E3), and A.D. 1470 (1360-1580) (E4). The ages of these paleoearthquakes yield a mean recurrence of 130+ or -40 yr. Although the mean recurrence is well determined for the period A.D. 1470-1868, individual interval are less well determined: E1-E2, 140 +80/-70 yr; E2-E3, 100 +90/-100 yr; and E3-E4, 150 +130/-110 yr.

The PSHA results are being used both for developing the seismic design of preclosure facilities and for evaluating the postclosure performance of the repository. The PSHA inputs were provided by 6 teams of 3 experts each for seismic source and fault displacement characterization (SSC) and by 7 individual experts for ground motion (GM) characterization. Approximately 20 faults within approximately 20 km of the site and up to 36 regional faults (out to approximately 100 km) were included in the SSC experts' characterizations. The most significant local faults included the Bow Ridge, Paintbrush Canyon, Solitario Canyon, and Stagecoach Road faults, which bound major crustal blocks at Yucca Mountain. These faults are characterized by low slip rates of approximately 0.001-0.05 mm/yr and recurrence intervals of 10,000 to more than 100,000 years. The experts' maximum magnitudes (Mmax) ranged from M 5.7-6.8. The most significant regional faults were the Death Valley and Furnace Creek faults with slip rates of 2.5-8.0 mm/yr and Mmax of M 7.0-7.5. Areal source zones were also characterized to account for background seismicity not associated with known faults and faults not specifically characterized by the experts; their parameters were derived from the historical seismicity record. Mmax in the range of M 6.0-7.5 were assigned to these zones. These Mmax were reduced to M 5.0-6.6 in the site vicinity because of the detailed characterization of faulting The GM experts estimated ground motions and uncertainties for a matrix of magnitudes, source-to-site distances, and faulting styles based on empirical data and numerical ground motion modeling. Attenuation relationships were derived from regressing on these ground motions. Based on the experts' input, the probabilistic hazard for ground shaking was calculated. Several approaches to characterize fault displacement potential were also developed by the SSC experts based primarily on paleoseismic observations of faulting at the site. Based on the experts' input, the probabilistic hazard for fault displacement was calculated at several points near and within the repository footprint.

Widespread debris flows, triggered by extraordinarily heavy rains in 1995, were a dramatic reminder that these fans are active landforms. Debris flow events, particularly those large enough to transport the greater than car-size boulders we sampled, can be a significant geologic hazard to those living on the fans; thus, it is important to know the age and recurrence interval of boulder deposition. We measured 10-Be and 26-Al in samples collected from the top of 21 boulders on the General's Fan, a complex landform adjacent to Kinsey Run in western Madison County, VA. Model exposure ages (SL, >60 degrees , 10-Be PR = 5.17 atoms/g) for these samples range from about 7 to 140 ky. There is no relation between boulder size or boulder height and age; nor is there strong spatial patterning of boulder ages on the fan surface. We do not know the nuclide activity that the boulders contained when they were deposited; nor do we know how much they have eroded since deposition. Large inventories of meteoric 10-Be, measured in soil profiles underlying the boulders, suggest that the fan surfaces on which the boulders sit are old and stable, the oldest exceeding 500 ky. An exceedance probability plot of boulder ages shows a non-random distribution through the last 150 ka. Boulder ages cluster in times known to be cold (18, 30, 67, 105, and 140 ky), consistent with periglacial processes supplying more boulders at high elevation and/or more moisture effective conditions catalyzing increased debris flow activity and boulder transport.

Using cosmogenic dating ( (super 10) Be) of boulders on moraines in Alcacocha Valley (S 11 degrees 03', W 75 degrees 58', elev. approximately 4100-4800 m), we have identified deposits ranging in age from the last glaciation ( approximately 12-31 ka) to >1.0 Ma. Moraines of the last glacial maximum are farther upvalley and smaller than large outer moraines of older glaciations. Preservation of the older moraines and of polished surfaces on some old boulders argues for extremely low boulder erosion rates. We estimate a maximum erosion rate of approximately 0.3 m/Myr, which approaches published rates for Antarctica and suggests that aridity is important in slowing boulder erosion. Our findings are consistent with results from other Andean locations where moraines of the last glacial maximum are less extensive than those of older glaciations. The apparent decrease in glacial extent and ice volume in the Junin Plain during the Quaternary may have been controlled by tectonics, climate, or a combination of both. A late Tertiary pulse of tectonism may have resulted in an increase in high-elevation topography in the Junin region, allowing growth of large ice masses. The subsequent trend in decreasing ice volume could be a result of either a decrease in the area of high-elevation topography through glacial erosion or a decrease in the amplitude of climate variability. These hypotheses could be tested by analysis of the sediment record preserved in the Junin basin.

Was this incision driven by tectonic or climatic forcing? When did it occur? In order to infer the cause and understand the timing, spatial distribution, and rate of the bedrock incision in two such gorges, we collected >70 samples for 10-Be and 26-Al analysis from exposed, fluvially eroded outcrops of quartz-bearing schist along strath terraces of the Potomac and Susquehanna Rivers at the Piedmont/Coastal Plain transition. Here we report primarily on the Potomac gorge. The first 18 samples, collected from Mather Gorge below Great Falls on the Potomac River, indicate that the most prominent strath terrace, a several km-long bedrock feature 20 to 25 m above the current low water level, was abandoned rapidly as the Potomac River incised about 30 kya (SL, >60 degrees , 10-Be PR = 5.17 atoms/g). Nine samples, collected from water-polished rock surfaces down a cross-section from this terrace to just above the river, have decreasing nuclide activities consistent with a fluvial, bedrock incision rate of about 70 cm/ky and an effective 6 ky exposure age at water level. Four samples, collected from below the normal low-flow level during the 2000 drought, have activities equivalent to about 5 ky of exposure. Thus, to account for cosmic-ray dosing at and just below the water's surface, we have subtracted 6 ky of exposure from older terrace surface ages. The incision of Mather Gorge began about 30 ky coincident with a major drop (>50 m) in eustatic sea level, the result of glacial ice-volume increase. Incision is clearly coincident with cooling climate but we do not know if it was driven by base-level fall or by changes in discharge and sediment loading. However, the similarity of model exposure ages for samples collected from a km-long transect parallel to the river and within 2 km of the present-day knick point at Great Falls, suggests that retreat of the knick point which formed the gorge must have been rapid, lasting only a few thousand years.

AN - 51860277; 2004-033184 AB - If it becomes necessary to purposefully capture and sequester fossil-fuel-generated CO (sub 2) , a variety of ocean, land, and underground storage options are being considered. However, many of these approaches are expensive, have potentially serious environmental impacts, and/or may ultimately be ineffective in keeping CO (sub 2) from the atmosphere. As an alternative we propose that CO (sub 2) -rich power-plant gases be first hydrated with seawater to produce a carbonic acid solution that in turn is reacted on-site with limestone to form primaily Ca (super 2+) and HCO (sub 3) (super -) . This calcium bicarbonate solution is then released and diluted in the ocean where it would add minimally to the existing, large pool of these ions in the sea. Such a process simply speeds up natural, abiotic carbonate weathering and dissolution which will otherwise consume anthropogenic CO (sub 2) , but over many millennia. Using a model of ocean chemistry and transport we show that this process would increase ocean alkalinity, helping to neutralize CO (sub 2) acidity and isolating anthropogenic carbon from the atmosphere. Relative to atmospheric release or direct CO (sub 2) injection into the sea, this method would greatly expand the capacity of the ocean to store anthropogenic carbon while minimizing environmental impacts of this carbon storage on ocean biota. Our calculations indicate that releasing the carbonate-dissolution effluent to the oceans would be less damaging to the marine environment than releasing an equivalent amount of CO (sub 2) directly to the atmosphere. This sequestration method is also less energy intensive and less expensive than abiotic CO (sub 2) capture and direct ocean or geologic injection schemes. We calculate an energy penalty that may be $90/tonne CO (sub 2) and >>20% energy penalties estimated for direct, deep ocean or subterranean CO (sub 2) injection. Our initial benchtop-scale experimental simulation of this process indicates that carbonate dissolution could contribute significantly to mitigating adverse impacts of fossil-fuel burning.

These data provide new information on Holocene climatic changes in the mid-continent of North America. The SL chronology is based on 26 AMS (super 14) C dates of terrestrial plant macrofossils, and the LO chronology is established with 8 AMS (super 14) C dates of charcoal flakes. An abrupt transition to warm/dry climatic conditions of the middle Holocene occurred at 7.8 cal ka, as indicated by increases in delta (super 18) O (-9.8 per mil to -7.3 per mil, SL), quartz content (10% to 43%, SL), aragonite/calcite ratio (0.7 to 1.4, LO), and non-arboreal pollen abundance (34% to 56%, SL). This transition probably resulted from a major reorganization in global atmospheric circulation, but it appeared to postdate the 8.2 ka event. Within the middle Holocene, our isotopic, mineralogical, and biological data exhibit two distinct climatic periods with warmer/drier conditions between 7.8 and 5.8 cal ka than between 5.8 and 3.5 cal ka. Superimposed on this pattern are millennial-scale shifts in drought intensity and prairie vegetation, as evidenced by oscillations in aragonite/calcite ratio, % Poaceae pollen, charcoal abundance, and C (sub 4) -plant abundance. For example, the aragonite/calcite ratio of the LO sediments reaches peak values at 7.5 cal ka, 6.2 cal ka, and 5.0 cal ka, suggesting driest climatic conditions at these times, and minimal values at 6.8 cal ka and 5.5 cal ka, suggesting wetter phases of the middle Holocene. These oscillations have a approximately 1300-year pacing but do not appear to coincide with the ice-rafted-debris events in the North Atlantic.

Water from each of these sources have unique chemical and isotopic fingerprints as well as varying residence times within a watershed. Monitoring changes in stream water chemistry through time provides a basis for determining the influence of each water source on the chemical composition of streams. Sagehen basin is a high elevation watershed in the Sierra Nevada near Truckee, California. Recent studies in Sagehen Basin revealed a positive correlation between residence times of shallow groundwaters and their chemical compositions. This relationship between residence times chemical compositions provides a framework for interpreting chemical changes in Sagehen Creek. Chemical and isotope composition data collected weekly from Sagehen Creek suggests that the delta O-18 of Sagehen Creek during the snowmelt period responds rapidly to snowmelt pulses. The delta O-18 ratio of Sagehen Creek is more negative and similar to isotope ratios measured in the snowpack early in the snowmelt period during the peak discharge. The subsequent increase in the delta O-18 during the baseflow recession is concurrent with the decrease in discharge. Changes in major ion chemistry, including calcium, sodium, magnesium, silica, potassium, occur simultaneously, however, the response lags approximately two weeks behind changes in delta O-18. During late summer and fall, the chemical and isotope composition of Sagehen Creek reflect that of shallow groundwater with a residence time of approximately 20 years. The stoichiometery of solutes in Sagehen Creek is related to the primary weathering reactions occurring the glacial till, and is consistent throughout the year, suggesting that the composition of shallow groundwater and dilution by snowmelt are the primary controls on the solute chemistry and delta O-18 composition of Sagehen Creek. Additionally, Sagehen Creek is more concentrated, and thus being fed by groundwater with longer residence times during periods of baseflow than other similar Sierra Nevada streams, suggesting a substantial groundwater system is supporting this watershed.

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

One approach is to sequester less-pure CO2 waste streams that are less expensive or require less energy to separate from flue gas, a coal gasification process, etc. The objective of this research is to evaluate the impacts of CO2 itself, as well as an impure CO2 waste stream, on geologic sequestration using reaction progress models, reactive transport simulators and analogous reactive transport experiments run in a plug flow reactor. We have investigated two generic reservoir rock scenarios: a feldspathic sandstone and a mixed calcite/dolomite carbonate. Models and experiments reacted these rocks with aqueous fluids that were initially equilibrated with respect to supercritical CO2 under anticipated disposal temperatures and pressures. The contaminant gases included H2S and SO2 and in our kinetic modeling we specifically accounted for acid catalysis of mineral dissolution reactions. Our modeling results with the sandstone reservoir rock suggested the possible formation of the mixed hydroxyl carbonate mineral dawsonite (NaAlCO3(OH)2). We are investigating this possibility by running closed system experiments in flexible gold bag reactors under conditions that should favor its formation. Our initial reactive transport experiments in the plug flow reactor will use sandstone from the Frio Fm (TX) and are designed to provide information useful in planning a CO2 geologic sequestration pilot field project.

In situ mollusks that are radiocarbon dead (>54,000 yr BP, Loken, 1966) led to the interpretation of the delta as an early Wisconsinan or pre-Wisconsinan ice-marginal feature. Hence, the delta became the cornerstone of the minimal model for Laurentide ice extent in the eastern Canadian Arctic during the Last Glacial Maximum (LGM). Large boulders resting on delta surfaces have been explained previously by 1) iceberg rafting, 2) surface reworking by sea-ice, or 3) mass wasting from glacier margins. We used cosmogenic nuclides to date four boulders lying on the surface of Cape Aston delta and one frost-rived block from a nearby bedrock knoll (125 m asl). Three of the four boulders exhibit LGM 10Be exposure ages (12.0+ or -0.5 ka, 17.6+ or -0.5 ka, 13.6+ or -0.4 ka; using 5.17 10Be PR), whereas the fourth boulder and the bedrock sample from the knoll have pre-LGM ages (96.2+ or -2.4 ka and 140.6+ or -3.5 ka, respectively). Because the highest dated LGM shoreline in the area lies at approximately 30 m asl, deposition of the boulders cannot be explained by 1) or 2) above. Mass wasting, 3) above, such as debris flows or slush avalanches, could explain deposition of some boulders, if the LGM ice margin were near the delta apex, but probably not the largest boulders, which are up to 10 m in diameter. Moreover, boulders are not found within sediments exposed by numerous deep meltwater channels that dissect the delta surface. We propose an alternative explanation, deposition of boulders by cold-based LGM ice. Thus, this foreland, and perhaps others along the NE Baffin Island coast, was glaciated by non-erosive cold-based ice during the LGM, leaving the underlying in situ shells and pre-LGM delta undisturbed. This scenario is compatible with recent exposure dating evidence for vigorous warm-based ice streams that occupied Baffin fiords during the LGM. Ongoing work involves analysis of dozens of additional samples collected from boulders on Cape Aston delta and from boulders and bedrock on the highest ground (up to 550 m) across the surrounding forelands to determine both lateral and vertical extent of LGM ice.

Successful implementation of this approach hinges on our ability to predict the relative effectiveness of subsurface CO (sub 2) migration and sequestration processes as a function of key reservoir and cap-rock properties, which will enable us to identify optimal target formations and evaluate their long-term isolation performance. Quantifying this functional relationship requires a modeling capability that explicitly couples multiphase flow and kinetically controlled geochemical processes. We have developed a unique computational package that meets these criteria by integrating a state-of-the-art reactive transport simulator (NUFT) and supporting geochemical software and databases (SUPCRT92 and GEMBOCHS). We have used this capability to model saline-aquifer disposal at Statoil's North-Sea Sleipner facility during both prograde (active-injection) and retrograde (post-injection) phases of the process. Simulation results suggest that in the near-field environment of Sleipner-like settings roughly 85% by mass of injected CO (sub 2) remains and migrates as an immiscible fluid phase (subject to hydrodynamic and structural trapping), about 15% dissolves into formation waters (solubility trapping), and <1% precipitates as carbonate minerals (mineral trapping). Although seemingly negligible, mineral trapping has enormous strategic significance. We have identified four distinct mechanisms: siderite-magnesite precipitates within inter-bedded and cap-rock shales, dawsonite cementation occurs throughout the intra-aquifer plume, and siderite-magnesite-calcite rind forms along both lateral and upper plume boundaries. Local porosity and permeability are reduced by each of these mechanisms; however, such reduction is most extreme in clay-rich shales, owing to their relatively large Fe and Mg concentrations. In our 20-year simulations, initial porosity and permeability of the basal cap-rock shale have been reduced by 8% and 22%, respectively. Hence, the strategic significance of mineral trapping: it continuously improves seal integrity and therefore containment of the voluminous immiscible plume and solubility-trapped CO (sub 2) .

We measured concentrations of cosmogenic nuclides in quartz extracted from stream sediment from 13 catchments to provide estimates of erosion rates at time scales from 10 (super 3) to 10 (super 5) yr. Preliminary analysis of 10Be activity from small (<50 km (super 2) ), upland catchments in Colorado and Wyoming indicates that the landscape is lowering at rates between 14 and 250 m/MY in this semiarid area. We sampled basins that: (1) have not been glaciated; (2) have only small volumes of sediment stored beneath terraces and in colluvium, and (3) display minimal evidence for anthropogenic disturbance. We measured the (super 10) Be content of the 250 to 710 mm sand fraction collected in cross-channel transects. Our initial data do not show strong influence of basin relief, average slope, drainage area, tectonic environment, or climate. However, the range of erosion rates from different lithologies suggests that relative rock resistance exerts strong control on landform evolution in the Rocky Mountain region. Catchments draining weathered Precambrian basement (granites and gneisses) typical of the northern Front, Laramie and Medicine Bow Ranges give erosion rates of 18 to 30 (24+ or -6; n = 9) m/MY. Weakly lithified Middle and Upper Cenozoic basin fill is eroding at rates of 45 to 250 m/MY at sites in southern Wyoming and northern Colorado. Precambrian quartzite exposed in the eastern Uinta Mountains gave a rate of 14 m/MY, the lowest we measured. Erosion rates measured in upland granitic and gneissic catchments in Colorado are comparable to those measured in other non-orogenic areas such as the southern Appalachians. If our initial measurements for erosion rates of weakly lithified basin fill are typical, most of the middle and late Cenozoic fill in the greater Wyoming area could have been stripped in the past 5 to 10 million years.

Dismukes et al. (2001) argued that bicarbonate preceded water as the preferred reductant for oxygenic photosynthesis, postulating a transition stage in the Archean when a bacterial photosynthetic precursor to cyanobacteria utilized bicarbonate, then with the drop of carbon dioxide level cyanobacteria emerged using water instead of bicarbonate. Thermodynamic calculations give a 5 to 10 fold drop in bicarbonate levels with the onset of a methane-dominated greenhouse assuming surface temperatures of about 60 degrees C and a drop in the level of atmospheric carbon dioxide from about 1 to <0.03 bars. Cyanobacterial emergence at 2.8 Gya coincides with the first evidence of atmospheric methane, the negative excursion in the organic carbon isotope record. We propose that the long-term buildup of atmospheric methane in the early Archean culminated with a methane-dominated greenhouse at about 2.8 Gya, with a concomitant reduction in atmospheric carbon dioxide levels. Surface temperatures were declining from about 80-85 to 60-70 degrees C from 3.8 to 2.8 Gya, with temperature the stronger driver of silicate weathering than atmospheric carbon dioxide level (Schwartzman, 1999). Far less methane is needed to maintain climatic temperatures than carbon dioxide. This scenario is also consistent with lower ambient temperatures for this transition. Thus, we propose the onset of the methane-dominated greenhouse triggered the emergence of cyanobacteria. The earlier emergence of phototrophy is consistent with its upper temperature limit of about 75 degrees C. The proposed drop in atmospheric carbon dioxide level had two consequences, the emergence of cyanobacterial oxygenic photosynthesis and its carbon dioxide-concentrating mechanism, an adaptation to declining carbon dioxide to oxygen ratios in the external environment since the Archean greenhouse transition.

The Dong Co conjugate fault system is centered along the E-trending Bangong-Nujiang suture zone. The conjugate fault system is comprised of the NE-striking left-slip Riganpei Co fault to the north and NW-striking right-slip Gyaring Co fault to the south. These structures accommodate a portion of Indo-Asian convergence and long term slip-rates determined along these faults indicate north-south contraction is occurring across Central Tibet at a rate of approximately 2 mm/yr. Preliminary interferograms were constructed using descending orbital tracks of the ERS 1 and ERS 2 European Space Agency satellites with a time-span of seven years. Surface displacement maps along the radar line of sight indicate a significant strain gradient from the NW to SE centered along the Riganpei Co fault, and is consistent with left-slip. Our preliminary InSAR results are consistent with geologic observations and suggest little variation in the near-field strain rate since about 7 ka.

These decisions typically require data interpretation by technical analysts who add their site-specific and professional knowledge to evaluate the significance of these data. For many large sites, simply handling the large database of ground water, chemical and geological data can prove a difficult and time-consuming task. Many sites have invested in geographic information systems (GIS) to address this problem. However, these applications still require input from technical analysts to integrate and interpret the wide range of data to produce results that are useful to decision makers. Therefore, computer algorithms are a cost-effective means to aid analysts in preparing the maps needed by managers to make timely project decisions. At Lawrence Livermore National Laboratory, the development of a consistent set of ground water elevation, plume, and geology maps that cover the entire project history was essential for implementing and managing the extensive remediation system. These maps were required for each hydrostratigraphic unit (HSU) defined in the site conceptual model. To accomplish this task, a rule-based computer algorithm was developed to create a consistent procedure that integrates multiple data sets both spatially and temporally based on a rigorous set of rules. The resulting maps were reviewed with respect to the site hydrogeological conceptual model to verify accuracy and consistency. Once the procedure was verified, the algorithm allowed for the rapid generation of thousands of dependable site maps covering the entire project history. The purpose of the algorithm is to support the technical analyst by allowing more time spent on data analysis rather than data compilation. By using this rule-based computer algorithm, LLNL has been able to maintain a strong data analysis support effort for decision-makers even as resources and staff have been re-directed to other aspects of the project. This work was performed under the auspices of the U.S. Department of Energy by the University of California, Lawrence Livermore National Laboratory under contract No. W 7405-Eng-48.

The DST is designed to investigate the coupled thermal - mechanical - hydrologic - chemical (TMHC) processes expected in a geological high-level nuclear waste repository. The heat source in the DST includes nine floor heaters in the 48-m long Heater Drift (HD), and 25 wing heaters that extend about 10 m outward from both sides of the HD. The parameters measured in the DST include heater power, temperature, moisture content, rock mass displacement, air permeability, thermal conductivity and thermal diffusivity, deformation in the concrete liner, and chemistry of gas and water samples. The heating phase of the DST was from December 3, 1997 to January 14, 2002. By October 2002 the DST will be in its ninth month of the planned 4-year natural cooling phase. The rock mass temperature in the DST is measured with resistance temperature devices (RTD) that are grouted in 28 holes. The measured temperatures provide good indications of the thermal-hydrologic processes during the test. The temperature-time history at each RTD shows that the dominant processes are heat conduction, and evaporation and boiling of pore water. Spatial variation of temperature shows the balancing of energy by thermal-hydrologic processes. The spatial distribution of the temperature-time curves shows that the boiling point of the pore water may vary with distance from the heat source, indicating the effect of the thermal-hydrologic-chemical process. The boiling point of the pore water may have been influenced by the variation of water chemistry caused by rock-water interactions.

Interestingly, extensive areas of the park were formerly occupied by military bases and only minimally developed. GGNRA is a wonderful field trip destination for adult education divisions of UC Berkeley and other Bay Area institutions because it highlights a wide variety of geologic subjects and processes. The adult education courses attract students from many different professions, although K-12 teachers primarily request credit for the classes. GGNRA includes rocks that formed at divergent, convergent, and transform plate boundaries and that record interactions of the North American, Pacific, and Farallon plates during the past 200 Ma. The Marin Headlands north of the Golden Gate Bridge include Mesozoic pillow basalts that formed on the Farallon plate at a divergent boundary, and the overlying radiolarian ribbon cherts record 100 Ma of starved sedimentation as the plate traveled across the Pacific Basin. The serpentine, sandstone/shale melange, and metamorphic blocks of the Franciscan complex near the south side of the Golden Gate Bridge record subduction processes and development of shear zones at a convergent plate boundary. The Franciscan subduction complex of the North American plate is separated from the granitic basement rocks of the Salinian terrane on the Pacific plate at Point Reyes National Seashore by the San Andreas transform fault. The Salinian terrane records significant lateral displacement from at least Southern California. The class discussions also focus on Quaternary climatic cycles and resulting sea level fluctuations as well as their influence on the evolution of San Francisco Bay and surrounding areas. Finally, the topic of man as an agent of geologic change in the Bay Area is related to historical events since the gold rush of 1849. Teaching adult education courses in GGNRA is extremely rewarding because of the students' genuine interest in geology and their desire to learn about the processes that shaped familiar landscapes through time and space.

A long-standing debate over the reconstruction of former ice sheets revolves around the use of relative weathering of landscapes, i.e., the assumption that highly-weathered landscapes have not been recently glaciated. New cosmogenic isotope measurements from northeastern Baffin Island shed light on this debate. Average (super 10) Be and (super 26) Al ages for two tors on a approximately 500 m upland adjacent to the mouth of Clyde Inlet, a 150-km-long fiord that penetrates interior Baffin Island, are >66.9+ or -5.1 ka and >62.1+ or -1.8 ka (SL, >60 Be PR = 5.1 atoms/g; Al PR = 31.1 atoms/g). The tors, on local summits approximately 100 m above the highest lateral moraines and other clear signs of actively-eroding ice, are deeply weathered, exhibiting large weathering pits, grus, and quartz veins and knobs that stand in relief. Three erratics perched directly on the ancient tors have average (super 10) Be and (super 26) Al ages of 16.7+ or -1.3 ka, 11.9+ or -0.6 ka, and 10.5+ or -0.8 ka. These results suggest that non-erosive ice overran highly-weathered upland surfaces along the northeastern margin of the LIS during the LGM. These data invalidate the use of relative weathering to define LIS margins in the eastern Canadian Arctic, and possibly elsewhere, especially where perched blocks have been described on weathered upland surfaces along the fringes of Northern Hemisphere Pleistocene ice sheets. The proximity of non-erosive plateau ice to erosive fiord ice requires strong gradients in basal thermal regimes, suggestive of an ice-stream mode of glaciation. We propose that this style of glaciation dominated the fiord coastline of northeastern Baffin Island where the topography and glacial geology is similar to the Clyde region. Ice-stream-dominated ice-sheet margins are dynamic and unstable, and consequently, the northeastern margin of the LIS was probably involved in abrupt climate changes, especially those including the coupling of ice sheets and oceans (e.g., Heinrich Events).

Vital to the operation of the canal is the large and consistent supply of water from the Rio Chagres basin mediated by Lake Alhajuela, the reservoir to the Panama Canal. In addition to water, the headwater basins supply sediment that reduces the storage potential of the reservoir. We chose the headwater basin of the Rio Chagres to investigate the background rates of sediment generation in a tropical montane environment. Development of the headwaters of the Rio Chagres is minimal and is mostly contained to the Rio Piedras tributary. We collected eight sediments from small tributaries to determine sediment generation on steep hillslopes using cosmogenic (super 10) Be. We collected nine sediment samples at major tributary junctions down the drainage network to determine the spatial distribution of sediment generation rates. A sediment sample taken from the mouth of the Rio Chagres, at Lake Alhajuela, provides an integrated sediment yield estimate from the entire basin. Since the slopes of the Rio Chagres basin are steep, sediment delivery from the hillslopes to the river is by a combination of landslides and diffusive hillslope processes. To understand better the sediment delivery processes we analyzed additional grain sizes for eight samples. Preliminary results from two samples collected from the Rio Chagres at the confluence of Rio Piedras and the confluence of the Rio Chagricito suggest basin wide erosion rates of 80+ or -11 and 70+ or -9 mm ky (super -1) , respectively. These values are similar to the suspended sediment yield data, which can be interpreted as an average basin erosion rate of 95 mm ky (super -1) . These preliminary results suggest that the mostly undisturbed tropical Rio Chagres basin is supplying sediment at similar rates as the long-term basin wide sediment generation. The network analysis of (super 10) Be provides natural rates of sediment yield with which to compare to long records of suspended sediment loads. Such analysis is particularly important in tropical basins that are ecologically fragile and are susceptible to human disturbance.

Our results document the existence of three chemical processes that probably occur in large icy satellites as a result of high pressure hydrothermal processing: (1) the formation of low-density hydrated silicates, (2) the alloying of iron and sulfur to form FeS-dominated cores, and (3) the instability of organic material relative to carbonates. We construct new internal models of the thermal and structural state of Ganymede, and infer that the magnetic field of this body arises from convection within a mostly iron sulfide core. Simple thermochemical calculations are conducted to further explore the likely effects of composition and oxygen fugacity on the high pressure chemistry undergone by organic material within icy satellites. Both experimental and calculated results show that primordial organics are likely to have been largely oxidized to carbonates through hydrothermal processing early in Ganymede"s history, potentially sterilizing Ganymede's H (sub 2) O layer.

As a result, two new local meteoric water lines were defined for the study area. Isotopic analyses of groundwater samples from over 200 springs and wells indicate that the main source of water to the Batinah coastal alluvial aquifer is high-altitude rainfall from the adjacent Jabal Akhdar Mountains, originating from a combination of northern and southern moisture sources. The groundwater recharged at high-altitude forms two plumes of water which is depleted in the heavy isotopes super(18)O and super(2)H and stretches from the mountains across the coastal plain to the sea, thereby retaining a chemical homogeneity horizontally and vertically down to a depth exceeding 300 m. In contrast, in areas adjacent to these two plumes the alluvial aquifer is geochemically stratified. Near the coast, saline intrusion results in abrupt changes in chloride concentrations and isotope values.

One reason for emphasis on the study of individual trace elements has been the difficulty of measuring their concentration against a background of more abundant dissolved sea salts. Now that many of these methodological problems have been addressed, we are discovering relationships between the oceanic distribution and concentration of trace elements and variations in biological productivity, geological activity, weather and climate, and other significant environmental effects. (Note: A number of trace elements have been considered as potential limiting nutrients controlling oceanic productivity.

AN - 72135994; 12351155 AB - We are working to understand possible human health effects from exposure to heterocyclic amines that are formed in meat during cooking. Laboratory-cooked beef, pork, and chicken are capable of producing tens of nanograms of MeIQx, IFP, and PhIP per gram of meat and smaller amounts of other heteroyclic amines. Well-done restaurant-cooked beef, pork, and chicken may contain PhIP and IFP at concentrations as high as tens of nanograms per gram and MeIQx at levels up to 3 ng/g. Although well-done chicken breast prepared in the laboratory may contain large amounts of PhIP, a survey of flame-grilled meat samples cooked in private homes showed PhIP levels in beef steak and chicken breast are not significantly different (P=0.36). The extremely high PhIP levels reported in some studies of grilled chicken are not seen in home-cooked samples.Many studies suggest individuals may have varying susceptibility to carcinogens and that diet may influence metabolism, thus affecting cancer susceptibility. To understand the human metabolism of PhIP, we examined urinary metabolites of PhIP in volunteers following a single well-done meat exposure. Using solid-phase extraction and LC/MS/MS, we quantified four major PhIP metabolites in human urine. In addition to investigating individual variation, we examined the interaction of PhIP with a potentially chemopreventive food. In a preliminary study of the effect of broccoli on PhIP metabolism, we fed chicken to six volunteers before and after eating steamed broccoli daily for 3 days. Preliminary results suggest that broccoli, which contains isothiocyanates shown to induce Phases I and II metabolism in vitro, may affect both the rate of metabolite excretion and the metabolic products of a dietary carcinogen. This newly developed methodology will allow us to assess prevention strategies that reduce the possible risks associated with PhIP exposure.

AN - 72133371; 12351150 AB - 2-Amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP), a mutagen/carcinogen belonging to the class of heterocyclic amines (HCAs) found in cooked meats, is a known rat mammary gland carcinogen. To gain insight into the genomic alterations associated with PhIP-induced carcinogenesis, we used comparative genomic hybridization (CGH) to examine chromosomal abnormalities in rat mammary gland carcinomas induced by PhIP. The alterations were compared to those induced by 7,12-dimethylbenz[a]anthracene (DMBA), a potent and well-studied mammary carcinogen. All six PhIP-induced carcinomas examined by CGH showed losses in the same specific regions of chromosomes 2, 3, 11, 18, and X, whereas three carcinomas induced by DMBA showed no consistent patterns of chromosomal gain or loss. This indicates that PhIP has a recognizable cytogenetic signature in rat mammary gland carcinomas.

AN - 72132782; 12351147 AB - N-oxidation by cytochrome p450 enzymes is an initial step in the metabolic activation of aromatic amine compounds. Once metabolized, these compounds are converted to DNA-reactive species which can exhibit potent mutagenic and/or carcinogenic activity. The precise mechanism of p450 enzyme oxidation is not completely understood, although various theories, involving either one-electron transfer, two-electron transfer or addition-rearrangement, have been debated. In previous studies, selection of the most probable mechanism has been based on consideration of Hückel theory charge distribution calculations and experimentally-derived enzyme metabolism data. This approach can now be improved by incorporating contemporary, ab initio quantum chemical methods to accurately determine the chemical properties of p450 aromatic amine substrates. In this work, we have re-examined the feasibility of three proposed p450 oxidation mechanisms by comparing the experimental oxidation yields and rates of 1-naphthylamine (1-NA), 2-naphthylamine (2-NA) and 2-aminofluorene (2-AF). This data has then been analyzed with respect to ab initio-calculated charge distributions and energies of reactants, oxidation products and proposed intermediates. Our analysis of theoretical and experimental data indicates that the one-electron model is more consistent with oxidation rate data for 1-NA, 2-NA, and 2-AF. We therefore conclude, in contrast to earlier studies, that the one-electron mechanism is more likely to be the pathway for p450-catalyzed aromatic amine oxidation.

The target gene, bssA, codes for the alpha -subunit of benzylsuccinate synthase. The primer-probe set for real-time PCR was based on consensus regions of bssA from four denitrifying bacterial strains; bssA sequences for two of these strains were determined during this study. The method proved to be sensitive (detection limit ca. 5 gene copies) and had a linear range of >7 orders of magnitude. We used the method to investigate how gasohol releases from leaking underground storage tanks could affect indigenous toluene-degrading bacteria. Microcosms inoculated with aquifer sediments from four different sites were incubated anaerobically with BTEX (benzene, toluene, ethylbenzene, and xylenes) and nitrate in the presence and absence of ethanol. Overall, population trends were consistent with observed toluene degradation activity: the microcosms with the most rapid toluene degradation also had the largest numbers of bssA copies. In the microcosms with the most rapid toluene degradation, numbers of bssA copies increased 100- to 1000-fold over the first 4 days of incubation, during which time most of the toluene had been consumed. These results were supported by slot blot analyses with unamplified DNA and by cloning and sequencing of putative bssA amplicons, which confirmed the real-time PCR method's specificity for bssA. Use of a companion real-time PCR method for estimating total eubacterial populations (based on 16S rDNA) indicated that, in some cases, ethanol disproportionately supported the growth of bacteria that did not contain bssA. The real-time PCR method for bssA could be a powerful tool for monitored natural attenuation of BTEX in fuel-contaminated groundwater. To our knowledge, this is the first reported molecular method that targets anaerobic, hydrocarbon-degrading bacteria based on a catabolic gene.

This paper assesses the extent to which particulate organic carbon (POC) transport to the ocean's interior can be predicted from primary production or export flux. Relationships between POC flux and depth are generally described by a uniform power law or rational decrease with depth, scaled to new or total primary production of POC. These relationships are studied through a review of parameters derived from (super 14) C uptake experiments, regional remote sensing, (super 234) Th studies, nitrogen balances, and sediment trap records. Ocean regions considered include sites studied by the Joint Global Ocean Flux Study, Hawaii Ocean Time-series, and Bermuda Atlantic Time-series Study programs and the Southern Ocean and involve observed and radiochemically corrected flux to depth. The paper demonstrates regional variability in the efficiency of the biological pump to transport organic carbon from surface waters to the ocean's interior. (modified journ. abst.)

Those results may be due to (a) confounding unaddressable by any county-level ('ecological') study design, or (b) county-level factors such as Rn/smoking or age/radon correlations or exposure misclassifications from the use of disparate data sources. Possibilities (b) were addressed by comparing age-specific LCM rates for white women in 2821 U.S. counties who died in 1950-54 at age 40+ ( similar to 11% of whom ever smoked), or at age 60+ ( similar to 5% of whom ever smoked), to county Rn levels newly estimated from U.S. Rn, climatic and geological-survey data. Significant negative LCM v Rn trends were found for both age groups, after adjusting for age and subsets of 21 county-level socioeconomic, climatic and other factors. Negative trends were largest for counties with less than or equal to 100 Bq m super(-3) Rn (p less than or equal to 0.00087; 420 analyses). Adjusted relative risk (RR sub(adj)) for LCM was significantly elevated (1 150 Bq m super(-3) v 65-100 Bq m super(-3) Rn, most involving adjustment for climate- and education-related factors likely to have influenced exposure to indoor air contaminants such as Rn and cigarette smoke. Though inconclusive due to potential ecological-fallacy-related confounding that could not be controlled, results from this ecological study are most consistent with a U-shaped dose-response relationship between 1950-54 LCM risk and U.S. residential radon in white women who predominantly never smoked.

AN - 71977330; 12160888 AB - Adaptive response is a term used to describe the ability of a low, priming dose of ionizing radiation to modify the effects of a subsequent higher, challenge dose, but it has been observed to be highly variable in both presence and magnitude. To examine this variability, 10 human lymphoblastoid cell lines were screened for adaptability to 137Cs radiation by determining the frequency of micronuclei in binucleated cells. Of these, six adapted, three did not adapt and one was synergistic. The assay was then repeated on each of the cell lines to test for reproducibility. Five cell lines showed the same result both times; four of these adapted and one did not. To determine whether fluctuations in the cell cycle distribution in the irradiated population of cells could alter the adaptive response, and therefore explain some of the observed variability, two of the cell lines were tested for adaptation after enriching the population, by synchronization, for a given cell cycle stage. In both cell lines, the direction of the response was altered when the distribution of cells within the cell cycle was changed, suggesting that the adaptive response can be affected by cell cycle stage at the time of irradiation.

Above the eastern portion of the Wadati-Benioff zone however, there is a distinct lack of volcanism (the Denali volcanic gap). We observe high Poisson's ratio values (0.29-0.33) over the entire length of the Alaskan subduction zone mantle wedge based on regional variations of Pn and Sn velocities. High Poisson's ratios at this depth (40-70 km), adjacent to the subducting slab, are attributed to melting of mantle-wedge peridotites, caused by fluids liberated from the subducting oceanic crust and sediments. Observations of high values of Poisson's ratio, beneath the Denali volcanic gap suggest that the mantle wedge contains melted material that is unable to reach the surface. We suggest that its inability to migrate through the overlying crust is due to increased compression in the crust at the northern apex of the curved Denali fault.

AN - 71933780; 12137994 AB - A decontamination method has been developed using a single reagent that is effective both against chemical warfare (CW) and biological warfare (BW) agents. The new reagent, "L-Gel", consists of an aqueous solution of a mild commercial oxidizer, Oxone, together with a commercial fumed silica gelling agent, Cab-O-Sil EH-5. L-Gel is non-toxic, environmentally friendly, relatively non-corrosive, maximizes contact time because of its thixotropic nature, clings to walls and ceilings, and does not harm carpets or painted surfaces. The new reagent also addresses the most demanding requirements for decontamination in the civilian sector, including availability, low maintenance, ease of application and deployment by a variety of dispersal mechanisms, minimal training and acceptable expense. Experiments to test the effectiveness of L-Gel were conducted at Lawrence Livermore National Laboratory and independently at four other locations. L-Gel was tested against all classes of chemical warfare agents and against various biological warfare agent surrogates, including spore-forming bacteria and non-virulent strains of real biological agents. Testing showed that L-Gel is as effective against chemical agents and biological materials, including spores, as the best military decontaminants.

Scanning Electron Microscopy and Energy Dispersive X-ray spectroscopic analysis were performed to identify the morphology and the bulk chemical composition. Glow-Discharge Mass Spectrometry and X-ray Diffraction analyses were also used to characterize the bulk chemical composition and crystalline structure of the deposits. In addition, X-ray photoemission and X-ray photoabsorption spectra for the deposits were compared to a series of Mn compounds to model and aid quantification of the constituents. Results reveal a mixture of Ca-sulfate, Mn-phosphate and Mn-oxide in the bulk of the deposits and a mixture of Mn-sulfate, Mn-phosphate and Mn-oxide on the surface of the deposits.

AN - 85354629; pmid-12186021 AB - Recently, it was shown that the time-reversal operator for a single, small spherical scatterer could have up to four distinguishable eigenstates [Chambers and Gautesen, J. Acoust. Soc. Am. 109, 2616-2624 (2001)]. In this paper, that analysis is generalized for scatterers of arbitrary shape and larger size. It is shown that the time-reversal operator may have an indefinitely large number of distinguishable eigenstates, with the exact number depending on the nature of the scatterer and the geometry of the time-reversal mirror. In addition, the case of a multiple number of well-separated scatterers is investigated, with the result that the total spectrum is the direct combination of the eigenstates associated with each scatterer. As an example, the singular value spectrum of the time-reversal operator for a linear array is calculated explicitly for bubbles and hard rubber spheres of finite size. Both resonance peaks and apparent crossing points can be observed in the spectrum as the size of the scatterer increases.

The distribution and oxidation state of arsenic (As) and selenium (Se) were also determined. The soil used in this study was formed from pyritic shale parent materials on the east side of the California Coast Range. Synchrotron-based X-ray fluorescence microprobe (mu -XRF) was used to generate elemental distribution maps of soil thin sections. Using the elemental distribution maps and optical micrographs, distinct mineral aggregates of iron oxide and iron sulfate were identified throughout the top horizon of the soil. These aggregates range in size from 10 to 100 mu m in diameter and can be found only a few micrometers apart. The As and Se concentrations in the iron oxide aggregates were 5-10 times the concentrations in the iron sulfate aggregates and the weathered shale matrix. This suggests that the As and Se become preferentially associated with iron oxides during the weathering process. Using a focused micron-sized beam, Fe, As, and Se X-ray absorption spectroscopy (XAS) data were collected from the sub-millimeter soil aggregates. The micro-extended X-ray absorption fine structure (mu -EXAFS) spectrum collected from the iron oxide aggregate revealed that its mineralogy was a combination of ferrihydrite (>50%) and goethite. The mu -EXAFS spectra from the iron sulfate region suggest that these aggregates contain jarosite. Using micro-X-ray absorption near edge spectroscopy (mu -XANES), oxidation states of the As and Se were determined. Arsenic was present in the iron oxide aggregate as As(V). Selenium was present in the soil as both Se(IV) and Se(VI), with a higher percentage of Se(VI) in the jarosite aggregate than the iron oxide aggregate. These results provide direct evidence of the distribution, oxidation states, and speciation of As and Se in the solid phase of an unaltered native soil. Information on the weathering and geochemistry of the pyritic materials, and the associated arsenic and selenium is useful for predicting the pedogenic processes of acid sulfate soils and the long-term fate of newly exposed pyritic materials (e.g., mine tailings and drained wetlands).

These moraines, deposited during the Mount Waskey advance, are several kilometers beyond modern glacier termini, and approximately 80 km upvalley of the late Wisconsin Ahklun Mountains ice cap terminal moraine. Eleven cosmogenic (super 10) Be and (super 26) Al exposure ages on moraine boulders, combined with radiocarbon ages from a lake core upvalley of a moraine deposited during the Mount Waskey advance, suggest that the advance culminated between 12.4 and 11.0 ka, sometime during, or shortly following, the Younger Dryas event (ca. 12.9-11.6 ka). We believe that the Mount Waskey advance was a consequence of cooling during the Younger Dryas. These data further strengthen emerging evidence for Younger Dryas-age cooling of the North Pacific region.

While evaluating this system off the Pacific coast of Baja California, we discovered Ba depletion greater than 60% in surface waters over tens of kilometers. Observed Ba abundance is among the lowest reported in any ocean water. No corresponding depletion was seen in Sr, which strongly suggests that acantharians are not the primary source of biogenic Ba in these surface waters.

This paper addresses hydrogeological issues at the 241-SX tank farm, especially focusing on Tank SX-108, which is one of the highest heat load, supernate density and ionic strength tanks at Hanford and a known leaker. The behavior of contaminants in the unsaturated zone near SX-108 is determined by an interplay of multiphase fluid flow and heat transfer processes with reactive chemical transport in a complex geological setting. Numerical simulation studies were performed to obtain a better understanding of mass and energy transport in the unique hydrogeologic system created by the SX tank farm. Problem parameters are patterned after conditions at Tank SX-108, and measured data were used whenever possible. Borrowing from techniques developed in geothermal and petroleum reservoir engineering, our simulations feature a comprehensive description of multiphase processes, including boiling and condensation phenomena, and precipitation and dissolution of solids. We find that the thermal perturbation from the tank causes large-scale redistribution of moisture and alters water seepage patterns. During periods of high heat load, fluid and heat flow near the tank are dominated by vapor-liquid counterflow (heat pipe), which provides a much more efficient mechanism than heat conduction for dissipating tank heat. The heat pipe mechanism is also very effective in concentrating dissolved solids near the heat source, where salts may precipitate even if they were only present in small concentrations in ambient fluids. Tank leaks that released aqueous fluids of high ionic strength into the vadose zone were also modeled. The heat load causes formation dry-out beneath the tank, which is accompanied by precipitation of solutes. These may become remobilized at a later time when tank temperatures decline and previously dried out regions are rewetted. Simulated temperature and moisture distributions compare well with borehole measurements performed in 2000. The temperature maximum observed beneath Tank SX-108 can be explained from past thermal history of the tank; it is not necessary to invoke heat generation from leaked radioactive contaminants. A novel composite medium model is used to explore effects of moisture tension-dependent anisotropy, which is shown to have important impacts on fluid flow and solute transport in the Hanford sediments.

These connections may be nearing their fatigue limit and will require increased inspection and repair over the next 10-20 years. The Winchester Bridge on Interstate 5 in Roseburg, Ore., required the extensive replacement of connection details because of fatigue crack growth. This report describes the results of a study to assess the loading conditions for the connection details on the Winchester Bridge. Finite-element modeling methods were used to characterize the structure, on both a global and local level. The global model provided the boundary conditions for the local model of the connection details. The local model included the effects of rivet preload and friction. Finite-element analysis results were validated by hand calculation. The analysis showed significant variation in connection detail stress range, depending on the detail's longitudinal and lateral location.

Rivers with point sources for super(129)I in their watersheds are drastically affected, while all rivers sampled show evidence for atmospherically transported super(129)I from the world's major nuclear fuel reprocessing facilities. Varying mixtures of oceanic cyclic salt and soil-derived iodine account for the observed spatial variation in iodine concentrations. A comparison of super(129)I concentrations in river and rainwater reveals concentration effects due to evapotranspiration.

We performed direct CO sub(2) injection simulations in both one-dimensional box-diffusion and three-dimensional ocean general circulation models. The 1-D model results for ocean carbon retention accord with the 3-D model results, especially in the Pacific basin and at shallower depths. In the 1-D model, carbon retention in the ocean is directly related to both the injection depth and the Delta super(14)C of carbon at the injection location. However, in the 3-D model, depth, but not radiocarbon, provides a relatively good prediction of carbon retention. This suggests that the expected time for a water parcel to return to the surface is closely related to its depth and not in general to the time since last at the surface.

AN - 71896399; 12113762 AB - Studies of other transgenic assays have shown that time after treatment is a very important variable in the analysis of mutation frequencies but that eventually a plateau frequency is reached, indicating that the mutations are neutral. This neutrality is very important for the design of both experiments and testing protocols. Here we show that the phiX174 am3, cs70 transgene gives qualitatively similar results to the other transgenes studied after exposure of the mice to N-ethyl-N-nitrosourea. In the small intestine, the mutant frequency induced by an acute dose did not change significantly from 10 to 70 days post-treatment, indicating that the mutations induced are, indeed, neutral. Likewise, the mutant frequency increased linearly with duration of exposure to ENU at a constant rate. Mutant frequencies obtained were 10 times higher from the chronic exposure than produced by a nearly lethal acute dose. As in previous comparisons of a transgene and the endogenous Dlb-1 locus in the small intestine, the chronic exposure was much more effective at increasing the sensitivity of the transgene than of the endogenous gene. The Dlb-1 locus shows more complex kinetics in this strain, as in others, with mutations initially accumulating at a slower rate, indicating a differential repair of genetic damage.

These cosmogenic nuclides demonstrate that Australian granite, exposed and sampled at 10 sites along a transect from the Eyre Peninsula (33 degrees S) to the Kakadu area in the Northern Territory (14 degrees S), has in some places eroded only decimeters over the past million years. However, nuclide activities are not saturated in any of the 61 exposed samples we analyzed, mandating that the surfaces we sampled are losing mass, albeit slowly, over time. Such mass loss indicates that inselbergs are dynamic landforms, confounding the assignment of discreet ages to inselberg surfaces. Nevertheless, the differential between slow rates of erosion measured on the very stable uppermost parts of these landforms and the more rapid rates measured below their flanks and below the adjacent grus-covered planes suggests that the forms of many large inselbergs, which stand meters to tens of meters high, must be at least Tertiary in age and possibly much older. Activities of (super 10) Be and (super 26) Al in 61 exposed Australian samples range from 5.1+ or -0.1X10 (super 6) to 5.3+ or -0.6X10 (super 5) atoms.g (super -1) and 2.1+ or - 0.1X10 (super 7) to 3.4+ or -0.5X10 (super 6) atoms.g (super -1) , respectively (normalized to sea level, at latitudes of >60 degrees , using only neutron scaling). Activities of (super 10) Be and (super 26) Al in seven shielded samples (3.5-13 m below the surface) are much lower, ranging from 3.4 + or - 0.2X10 (super 4) to 7.0+ or -0.1X10 (super 4) atoms.g (super -1) and 1.6+ or -0.1 X 10 (super 5) to 2.8+ or - 0.2X10 (super 5) atoms.g (super -1) , respectively. (super 26) Al/ (super 10) Be ratios of exposed samples range from 3.89+ or -0.19 to 6.29 + or - 0.82. If 2sigma uncertainty ranges and a nominal sea-level, high-latitude (super 10) Be-production rate of 5.17 atoms.g (super -1) .yr (super -1) are considered, ratio data for all but one surface sample are consistent with continuous surface or near-surface exposure and/or erosion. Rock surfaces farther north in Australia, where the climate is more humid, have lower nuclide activities; thus, we infer that surface stability is inversely related to mean annual precipitation. From 61 exposed samples, we calculated maximum limiting, single-nuclide, model erosion rates of 0.3+ or -0.1 to 5.7+ or -1.0 m/m.y. and minimum limiting, single-nuclide, model exposure ages of 105+ or -16 to 1310+ or -190 ka (by assuming a sea-level, high-latitude (super 10) Be-production rate of 5.17 atoms.g (super -1) .yr (super -1) ). Seven shielded samples, in which the nuclide inventory is muon-generated, also have nuclide activities consistent with similarly low rates of erosion but over even longer time scales. It appears that the Eyre Peninsula inselbergs have been and are eroding so slowly that they may well be direct descendents of Cenozoic and perhaps even Mesozoic forms.

Results from Boulder Canyon show that terrace heights above the modern channel (grade) can be divided into: (1) Bull Lake (> or =100 ka; 20-15 m above grade); (2) Pinedale (32-10 ka; 15-4 m above grade); and (3) Holocene age (15 m above grade record Bull Lake deposition. Well-preserved terraces of Pinedale age suggest that the range of terrace height above grade reflects short-term fluctuations in the river profile during periods of rapidly changing stream load and power. Net river incision apparently occurred during transitions to interglacial periods. Soil development and stratigraphic position, along with limited cosmogenic and (super 14) C dating, suggest that approximately 130 ka terraces in Boulder Canyon correlate with the Louviers Alluvium, and that 32 to 10 ka fills in the canyon correlate with the Broadway Alluvium on the adjacent High Plains. Late Pleistocene incision rates ( approximately 0.15 m ka (super -1) ) along Boulder Canyon exceed pre-late Pleistocene incision rates, and are higher than middle to late Pleistocene incision rates ( approximately 0.04 m ka (super -1) ) on the High Plains. This study provides an example of how modern geochronologic techniques allow us to understand better rivers that drain glaciated catchments.

We conducted field and greenhouse experiments to compare the rare heterostyle with a cryptic self-incompatibility system (A. grandiflora) to a common, self-compatible, homostylous, sympatric congener (A. tessellata). Inter-species comparisons of adult plants suggested that in the greenhouse, A. grandiflora balances low floral seed set (seeds per flower) with increased floral output (flowers/plant) and a greater number of flowers per inflorescence. Seed set from active self-, intra- and inter-morph pollinations was high in A. grandiflora, indicating that the cryptic self-incompatibility system does not prevent seed set in the species. In the field, A. grandiflora floral output was only slightly greater than for A. tessellata, and did not fully balance lower floral seed set. Amsinckia tessellata average seed weight was lower than that of A. grandiflora, which, along with the lower number of flowers produced, indicated lower maternal investment per nutlet than for A. grandiflora. Under conditions of unlimited resources, it appears that A. grandiflora fitness is not intrinsically limited when compared to its weedy relative A. tessellata. The differences in nutlet output between A. grandiflora and A. tessellata under field conditions are more likely due to differential responses to extrinsic factors such as competition and pollinator availability.

The survey shows that surface water in the San Diego Bay is clearly enriched in Mn, Ni, Cu, Zn, Cd, and FDOM with respect to the coastal ocean. Trace element enrichment patterns were used to identify bay water as it enters the coastal ocean during tidal pumping. Quantifying the spatial distribution and temporal flux of pollutant trace elements are important steps in understanding coastal biogeochemical processes.

An effective means to survey differences across whole genomes would be highly advantageous for understanding this variation. Here we show that suppression subtractive hybridization (SSH) provides high, representative coverage of regions that differ between similar genomes. Using Helicobacter pylori strains 26695 and J99 as a model, SSH identified approximately 95% of the unique open reading frames in each strain, showing that the approach is effective. Furthermore, combining data from parallel SSH experiments using different restriction enzymes significantly increased coverage compared to using a single enzyme. These results suggest a powerful approach for assessing genome differences among closely related strains when one member of the group has been completely sequenced.

AN - 71940545; 12136519 AB - Molecular targeted radionuclide therapy promises to expand the usefulness of radiation to successfully treat widespread cancer. The unique properties of radioactive tags make it possible to plan treatments by predicting the radiation absorbed dose to both tumors and normal organs, using a pre-treatment test dose of radiopharmaceutical. This requires a combination of quantitative, high-resolution, radiation-detection hardware and computerized dose-estimation software, and would ideally include biological dose-response data in order to translate radiation absorbed dose into biological effects. Data derived from conventional (external beam) radiation therapy suggests that accurate assessment of the radiation absorbed dose in dose-limiting normal organs could substantially improve the observed clinical response for current agents used in a myeloablative regimen, enabling higher levels of tumor control at lower tumor-to-normal tissue therapeutic indices. Treatment planning based on current radiation detection and simulations technology is sufficient to impact on clinical response. The incorporation of new imaging methods, combined with patient-specific radiation transport simulations, promises to provide unprecedented levels of resolution and quantitative accuracy, which are likely to increase the impact of treatment planning in targeted radionuclide therapy.

AN - 71800255; 12055289 AB - Yersinia pestis, the causative agent of bubonic plague, emerged recently (<20000 years ago) as a clone of Yersinia pseudotuberculosis. There is scant evidence of genome diversity in Y. pestis, although it is possible to differentiate three biovars (antiqua, mediaevalis or orientalis) based on two biochemical tests. There are a few examples of restriction fragment length polymorphisms (RFLPs) within Y. pestis; however, their genetic basis is poorly understood. In this study, six difference regions (DFRs) were identified in Y. pestis, by using subtractive hybridization, which ranged from 4.6 to 19 kb in size. Four of the DFRs are flanked by insertion sequences, and their sequences show similarity to bacterial genes encoding proteins for flagellar synthesis, ABC transport, insect toxicity and bacteriophage functions. The presence or absence of these DFRs (termed the DFR profile) was demonstrated in 78 geographically diverse strains of Y. pestis. Significant genome plasticity was observed among these strains and suggests the acquisition and deletion of these DNA regions during the recent evolution of Y. pestis. Y. pestis biovar orientalis possesses DFR profiles that are different from antiqua and mediaevalis biovars, reflecting the recent origins of this biovar. Whereas some DFR profiles are specific for antiqua and mediaevalis, some DFR profiles are shared by both biovars. Furthermore, the progenitor of Y. pestis, Y. pseudotuberculosis (an enteric pathogen), possesses its own DFR profile. The DFR profiles detailed here demonstrate genome plasticity within Y. pestis, and they imply evolutionary relationships among the three biovars of Y. pestis, as well as between Y. pestis and Y. pseudotuberculosis.

Crustal detachment has unroofed the ca. 8 Ma Cordillera Blanca batholith, now the backbone of the highest mountain range in Peru. Large-magnitude slip along the fault was thermally enhanced by emplacement of the batholith, the penultimate magmatic event prior to flattening of the Nazca slab. However, extensional models based on arc magmatism and crustal thickening alone do not adequately explain the scale or structural asymmetry of a series of young, deep-seated, west-dipping normal faults across Peru. Here we show that the onset of detachment faulting coincided with subduction of the aseismic Nazca Ridge and consequent flattening of the Nazca slab. We propose that slab buoyancy from ridge subduction triggered extensional collapse of the prethickened continental crust, and that this buoyancy drove footwall uplift that exceeds basin subsidence. The west-dipping asymmetry of late Cenozoic extensional faults in Peru may be controlled by a preexisting crustal anisotropy (older thrusts), and/or formation of Riedel-like shears kinematically linked to the flat Nazca slab.

Cosmogenic nuclide-based models suggest that the Iron and Granite Mountains generate 0.11-0.13 and 0.082-0.097 m (super 3) of sediment per year per meter of rangefront, respectively. The sediment moves down the piedmont in an active transport layer (ATL), which is 20 to 30 cm thick (based on visual observations, measurements of depth to a buried B-horizon, cosmogenic nuclide data, and maximum ephemeral channel depths). Sediment in this layer is well-mixed vertically and horizontally on the 10 (super 2) year time scale, indicating that the small ephemeral channels, which dominate the piedmont surface migrate quickly. Interpretive models of increasing nuclide activities at depth in two pits suggest steady sediment deposition on the piedmont (at rates between 17-21 and 38-45 m Ma (super -1) ) until the late Pleistocene epoch, when a discontinuity to markedly lower nuclide activities in the isotopically well-mixed active transport layer suggests that deposition stopped, a significant change in piedmont behavior. Nuclide activities in 10 amalgamated surface samples, each collected along a different 4-km-long transect, increase steadily away from the mountain front. Thus, we infer that sediment is uniformly dosed by cosmic rays as it is transported down the Iron and Granite Mountain piedmonts. Interpretive models suggest that long-term average sediment speeds down the Iron and Granite Mountain piedmonts are a few decimeters to a meter per year.

From the measurements, we determine long-term, time-integrated rates of upland sediment generation (81+ or -5 g m (super -2) year (super -1) ) and bedrock equivalent lowering (30+ or -2 m Ma (super -1) ) consistent with other estimates for regions of similar climate, lithology, and topography. In a small ( approximately 8 km (super 2) ), upland sub-basin, differences in nuclide concentrations between bedrock outcrops and hillslope colluvium suggest weathering of bedrock beneath a colluvial cover is a more significant source of sediment (40X10 (super 4) kg year (super -1) ) than weathering of exposed bedrock surfaces (10X10 (super 4) kg year (super -1) ). Mixing models constructed from nuclide concentrations of sediment reservoirs identify important sediment source areas. Hillslope colluvium is the dominant sediment source to the upper reaches of the sub-basin channel; channel cutting of alluvial terraces is the dominant source in the lower reaches. Similarities in nuclide concentrations of various sediment reservoirs indicate short sediment storage times (<10 (super 3) years). Nuclide concentrations, measured in channel sediment from tributaries of Yuma Wash and in samples collected along the length of the Wash, were used to construct mixing models and determine sediment sources to the main stem channel. We find an exponential decrease in the channel nuclide concentrations with distance downstream, suggesting that as much as 40% of sediment discharged from Yuma Wash has been recycled from storage within basin fill alluvium. Sediment generation and denudation rates determined from the main stem are greater (25%) than rates determined from upland sub-basins suggesting that, currently, sediment may be exported from the basin more quickly than it is being generated in the uplands. Independence of nuclide concentration and sediment grain size indicates that channels transport sediment in discrete pulses before rapidly depositing poorly sorted material, suggesting that differences in transport times for different size materials are minimal.

We demonstrate the ability of an algebraic multigrid algorithm (AMG) to efficiently solve the large, sparse systems of equations that result from computational models of ground water flow and transport in large and complex domains. Unlike geometric multigrid methods, this algorithm is applicable to problems in complex flow geometries, such as those encountered in pore-scale modeling of two-phase flow and transport. We integrated AMG into MODFLOW 2000 to compare two- and three-dimensional flow simulations using AMG to simulations using PCG2, a preconditioned conjugate gradient solver that uses the modified incomplete Cholesky preconditioner and is included with MODFLOW 2000. CPU times required for convergence with AMG were up to 140 times faster than those for PCG2. The cost of this increased speed was up to a nine-fold increase in required random access memory (RAM) for the three-dimensional problems and up to a four-fold increase in required RAM for the two-dimensional problems. We also compared two-dimensional numerical simulations of steady-state transport using AMG and the generalized minimum residual method with an incomplete LU-decomposition preconditioner. For these transport simulations, AMG yielded increased speeds of up to 17 times with only a 20% increase in required RAM. The ability of AMG to solve flow and transport problems in large, complex flow systems and its ready availability make it an ideal solver for use in both field-scale and pore-scale modeling.

This study compares abstracted, homogeneous representations of porosity and permeability, mineral surface areas and distributions, to discrete distribution representation of these same properties. Discretization was accomplished by high-resolution (ca. 1 mu m super(2)) characterization of fractured tuffaceous rock from Yucca Mountain, Nevada, using optical microscopy and X-ray fluorescence spectroscopy. A sample area of 10 super(6) mu m super(2) was mapped in detail, and the resulting element and porosity maps were digitized. The domain was decomposed into 12,208 cells that were 8.77 x 10 super(-6) m on a side. Simulations were conducted in which a dilute fluid enters the discretized porous medium at modest flow rates. Simulation results using a discrete mineral distribution point to the conclusion that slow flow rates, in which fluid residence times are on the order of days, provide fluid composition results that are very similar to those obtained from the homogeneous mineral distribution representation. At higher flow rates, where fluid residence times are on the order of hours, contrasts in fluid composition persist throughout the flow domain. The results demonstrate that the fluid composition characteristics in the homogeneous and discrete mineral representations will be similar only when the bulk average contact times for the individual mineral phases along the flow paths are approximately equivalent (within a few percent) for the two cases.

A novel IS10-like element, IS1330, uncovered by this technique was found to be uniquely present in high copy numbers among the highly pathogenic Y. enterocolitica 1B strains, while a single copy of the element was found in the low pathogenic Ye biogroup 4 serotype O:3 strain. The 1321-bp repetitive element has 19-bp imperfect inverted terminal repeats and is bracketed by a 10-bp duplication of the target sequence. The predicted transposase shares high homology with the IS10 open reading frame of the large virulence plasmid pWR501, of Shigella flexneri, with IS10 transposase of Salmonella typhi, and with IS1999 (tnpA) of Pseudomonas aeruginosa. The IS1330 tnp gene is transcribed in vitro and in vivo in HeLa cells. At least one copy of IS1330 flanks the recently described chromosomal type III secretion cluster in Y. enterocolitica WA-314, O:8, and future studies should shed light on whether this novel transposase mediates transposition events in highly pathogenic Y. enterocolitica strains, thus enhancing the genetic plasticity of this species.

AN - 71972770; 12153019 AB - RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine) is a nitramine explosive that has contaminated soil and groundwater at military installations throughout the US. Although anaerobic RDX metabolism has been reported, the process is not well understood, as past studies have typically involved complex, undefined media with multiple potential electron donors and acceptors. In this study, bacteria enriched from RDX-contaminated aquifer sediments consumed RDX in a defined, bicarbonate-buffered, anaerobic medium containing hydrogen as the sole electron donor and RDX as a potential electron acceptor and sole nitrogen source. RDX was not consumed in live controls that did not contain hydrogen. Transient formation of mononitroso- and dinitroso-RDX metabolites (hexahydro-1-nitroso-3,5-dinitro-1,3,5-triazine and hexahydro-1,3-dinitroso-5-nitro-1,3,5-triazine, respectively) was documented by liquid chromatography-mass spectrometry. However, studies with 14C-labeled RDX suggested that mineralization to carbon dioxide was negligible (<2%), which is consistent with cometabolic transformation. Several lines of evidence suggest that the RDX-transforming bacteria under study were homoacetogens, including correlations between RDX consumption and acetate production. Methanogens were unlikely to be responsible for RDX metabolism, as the presence of 2-bromoethanesulfonate, an inhibitor of methanogenesis, did not appear to affect RDX metabolism. The presence of nitrate reversibly halted RDX metabolism, whereas ammonium had no discernible effect, which implies that: (i) nitrate, which commonly occurs in RDX-contaminated groundwater, may inhibit in situ RDX metabolism, and (ii) although RDX may act as both a nitrogen source and cometabolic electron sink, the latter role predominates, as RDX reduction will proceed regardless of whether or not a more favorable nitrogen source is present.

AN - 71609059; 11955674 AB - Heterocylic amine (HA) compounds formed in the cooking of certain foods have been shown to be bacterial mutagens and animal carcinogens, and may be a risk factor for human cancer. To help explain the variation observed in HA formation under different cooking conditions, we have performed heat-flow simulations and experiments on the pan-frying of beef patties. The simulations involve modeling the heat flow within a meat patty using empirically derived thermal transport coefficients for the meat. The predicted temperature profiles are used to integrate the Arrhenius rate equation to estimate the concentration of HAs formed in the meat. We find that our simulations accurately model experimentally determined temperature profiles, cooking times, HA spatial distributions and total HA formation in patties that are flipped once during the pan-frying process. For patties flipped every 60 s, the simulations qualitatively agree with experiment in predicting reduced cooking times and HA formation relative to the singly-flipped patties. However, the simulations overestimate the effect of rapid flipping on cooking times and underestimate the effect of flipping on total HAs formed. These results suggest that the dramatic reductions in HA formation due to rapid flipping may be due to factors other than the heating process or that there is a critical feature of the flipping process that is not captured in our model.

During the late Quaternary, glaciers advanced at least eight times. By using (super 10) Be and (super 26) Al surface-exposure dating on moraine boulders and scoured bedrock, we determined the timing of glaciation for four of these glacial advances: ca. 54.7-43.2 ka (Borit Jheel glacial stage), ca. 25.7-21.8 ka (Ghulkin I glacial stage), ca. 18.4-15.3 ka (Ghulkin II glacial stage), and ca. 10.8-9.0 ka (Batura glacial stage). For two of the older advances, the Yunz and Shanoz glacial stages, our data set a limit of >60 ka. Although, at present, the uncertainties in dating make it impossible to describe unequivocally the climate processes controlling glaciations in the Hunza Valley, the results suggest that precipitation changes related to oscillations in the Southwest Asian monsoonal system combine with cooling that is broadly associated with Heinrich events to cause glacial advances in this region.

We used the Global Implicit Multicomponent Reactive Transport (GIMRT) code to model the processes occurring in the sediment column (diagenesis, sediment burial, fluid advection, and multicomponent diffusion) and to estimate net seafloor fluxes of solutes. Within the sediment section, the reactions controlling the concentrations of the solutes listed above are organic matter degradation via SO (sub 4) reduction, dissolution of amorphous silica, reductive dissolution of amorphous Fe(III)-(hydr)oxide, and precipitation of calcite, carbonate fluorapatite, and amorphous Fe(II)-sulfide. Rates of specific discharge estimated from pore-water Mg profiles are 2 to 3 mm/yr. At this site the basement hydrothermal system is a source of NH (sub 4) , SiO (sub 2(aq)) , and Ca, and a sink of SO (sub 4) , PO (sub 4) , and alkalinity. Reaction within the sediment column increases the hydrothermal sources of NH (sub 4) and SiO (sub 2(aq)) , increases the hydrothermal sinks of SO (sub 4) and PO (sub 4) , and decreases the hydrothermal source of Ca. Reaction within the sediment column has a spatially variable effect on the hydrothermal flux of alkalinity. Because the model we used was capable of simulating the observed pore-water chemistry by using mechanistic descriptions of the biogeochemical processes occurring in the sediment column, it could be used to examine the physical controls on hydrothermal fluxes of solutes in this setting. Two series of simulations in which we varied fluid flow rate (1 to 100 mm/yr) and sediment thickness (10 to 100 m) predict that given the reactions modeled in this study, the sediment section will contribute most significantly to fluxes of SO (sub 4) and NH (sub 4) at slow flow rates and intermediate sediment thickness and to fluxes of SiO (sub 2(aq)) at slow flow rates and large sediment thickness. Reaction within the sediment section could approximately double the hydrothermal sink of PO (sub 4) over a range of flow rates and sediment thickness, and could slightly decrease (by < or =10%) the size of the hydrothermal source of Ca.

The total water flow from all sampled cold springs was > or =1.8X10 (super 7) m (super 3) /yr draining an area that receives an estimated 2.5X10 (super 7) m (super 3) /yr of recharge, suggesting that sample coverage of the groundwater system was essentially complete. Some of the waters contain magmatic helium with (super 3) He/ (super 4) He ratios as high as 4.5 times the atmospheric ratio, and a magmatic component in the dissolved inorganic carbon (DIC) can be identified in virtually every feature sampled. Many waters have a (super 14) C of 0-5 pmC, a delta (super 13) C near -5 per mil, and contain high concentrations (20-50 mmol/l) of CO (sub 2(aq)) ; but are otherwise dilute (specific conductance = 100-300 mu S/cm) with low pH values between 5 and 6. Such waters have previously escaped notice at Mammoth Mountain, and possibly at many other volcanoes, because CO (sub 2) is rapidly lost to the air as the water flows away from the springs, leaving neutral pH waters containing only 1-3 mmol/l HCO (sub 3) (super -) . The total discharge of magmatic carbon in the cold groundwater system at Mammoth Mountain is approximately 20 000 t/yr (as CO (sub 2) ), ranging seasonally from about 30 to 90 t/day. Several types of evidence show that this high discharge of magmatic DIC arose in part because of shallow dike intrusion in 1989, but also demonstrate that a long-term discharge possibly half this magnitude ( approximately 10 000 t/yr) predated that intrusion. To sustain a 10 000 t/yr DIC discharge would require a magma intrusion rate of 0.057 km (super 3) per century, assuming complete degassing of magma with 0.65 wt% CO (sub 2) and a density of 2.7 t/m (super 3) . The geochemical data also identify a small (<1 t/day) discharge of magmatic DIC that can be traced to the Inyo Domes area north of Mammoth Mountain and outside the associated Long Valley caldera. This research, along with recent studies at Lassen Peak and other western USA volcanoes, suggests that the amount of magmatic carbon in cold groundwaters is important to constraining rates of intrusion and edifice weathering at individual volcanoes and may even represent a significant fraction of the global carbon discharge from volcanoes.

Three of our four trenches, trenches A, B, and C, were excavated across the 1999 Hector Mine rupture; a fourth trench, D, was excavated across a vegetation lineament that had only minor slip at its southern end in 1999. Trenches A-C exposed strata that are broken only by the 1999 rupture; trench D exposed horizontal bedding that is locally warped and offset by faults. Stratigraphic evidence for the timing of an earlier earthquake along the 1999 rupture across Lavic Lake playa was not exposed. Thus, an earlier event, if there was one along that rupture trace, predates the lowest stratigraphic level exposed in our trenches. Radiocarbon dating of strata near the bottom of trenches constrains a possible earlier event to some time earlier than about 4950 B.C. Buried faults revealed in trench D are below a vegetation lineament at the ground surface. A depositional contact about 80 cm below the ground surface acts as the upward termination of fault breaks in trench D. Thus, this contact may be the event horizon for a surface-rupturing earthquake prior to 1999-the penultimate earthquake on the Lavic Lake fault. Radiocarbon ages of detrital charcoal samples from immediately below the event horizon indicate that the earthquake associated with the faulting occurred later than A.D. 260. An approximately 1300-year age difference between two samples at about the same stratigraphic level below the event horizon suggests the potential for a long residence time of detrital charcoal in the area. Coupled with a lack of bioturbation that could introduce young organic material into the stratigraphic section, the charcoal ages provide only a maximum bounding age; thus, the recognized event may be younger. There is abundant, subtle evidence for pre-1999 activity of the Lavic Lake fault in the playa area, even though the fault was not mapped near the playa prior to the Hector Mine earthquake. The most notable indicators for long-term presence of the fault are pronounced, persistent vegetation lineaments and uplifted basalt exposures. Primary and secondary slip occurred in 1999 on two southern vegetation lineaments, and minor slip locally formed on a northern lineament; trench exposures across the northern vegetation lineament revealed the post-A.D. 260 earthquake, and a geomorphic trough extends northward into alluvial fan deposits in line with this lineament. The presence of two basalt exposures in Lavic Lake playa indicates the presence of persistent compressional steps and uplift along the fault. Fault-line scarps are additional geomorphic markers of repeated slip events in basalt exposures.

Hydrogel swelling in response to analyte concentration exerts contact pressure on a deformable conducting diaphragm, producing a capacitance change. Initial results are reported for testing device feasibility. Uncrosslinked PHEMA hydrogel was tested for swelling pressure in response to calcium nitrate tetrahydrate. Diaphragm deflection due to applied air pressure was measured on NiTi-based diaphragms and compared with hydrogel-actuated deflections of the same diaphragms to determine the pressure generating characteristics of the hydrogel. The PHEMA sample exhibited greatest sensitivity in the concentration range 0-0.5 M, generating an average of 110 mN/M/ mu l. The device was incorporated into a passive LC resonant circuit. Resonance frequency was measured as a function of applied air pressure, in the range of pressures generated by hydrogel swelling. Resonance frequency shifted from 66 MHz to 33 MHz over the pressure range 0-32 kPa, corresponding to an estimated average sensitivity of 66 Hz per mu mol of calcium nitrate tetrahydrate over the range 0-0.5 M.

This device provides a new treatment modality that could enable significant improvements in therapeutic stroke outcomes, ultimately improving mortality rates and decreasing morbidity, thereby reducing the cost of rehabilitation and improving the quality of life. Using differential scanning calorimetry (DSC) and dynamic mechanical thermal analysis (DMTA) to define the thermo-mechanical behavior of SMP, we provide useful information about the polymer structure, conditions for device actuation, and an estimate of the recovery forces the device is capable of delivering during the transition between it's straight and coiled shape. In addition, experimental determination of the maximum amount of pressure and force against which the microactuator coil can hold a clot is reported. The results of these tests establish that the device can successfully hold a clot against forces and pressures well above those expected in physiological systems for clot extraction, rendering it as an exciting new technology for treating ischemic stroke.

In vivo strong evidence of aneuploidy and polyploidy induction has been obtained in germ cells, especially in oocytes. More controversial are the data on the aneugenicity of griseofulvin in somatic cells. In this paper we provide evidence that GF induces non-disjunction and cell cycle delay in bone marrow cells of orally treated mice. Adult female mice were administered olive oil suspensions of 200, 666 or 2000 mg/kg GF by gavage and killed 18 or 24 h later. To minimize animal-to-animal variation in the absorption and distribution of GF, mice were fasted from the time of GF administration to the time of killing. Two hours before treatment the animals were s.c. implanted with a bromodeoxyuridine tablet to obtain differential chromatid staining and to determine the number of divisions after GF treatment for each metaphase. Mitostatic effects of GF were assessed by the relative proportions of first, second and third generation metaphases and the average generation time (AGT) method. A statistically significant increase with respect to the control AGT value was observed after treatment with 666 and 2000 mg/kg, suggesting that GF, as already shown in meiosis, interfered with cell cycle progression. Hyperploidy was scored in second generation metaphases. Eighteen hours after treatment, the frequencies of hyperploid cells were significantly (P < 0.05) higher in all GF-treated groups than in their matched control group. The effect was not dose-dependent. No further increase in aneuploidy was observed at 24 h, suggesting that cells overcoming mitotic arrest did not have a higher rate of non-disjunction. No induction of polyploidy was demonstrated. We conclude that GF induces mitotic delay and aneuploidy in mouse bone marrow and suggest that the protocol used to formulate the gavage suspensions and the after-treatment fasting of the animals enhanced the bioavailability of GF to bone marrow cells.

Some of the most promising applications of this approach are presently limited by the rate at which sequences can be analyzed. As a step toward overcoming this limitation, we have investigated the use of photolithography chip technology to perform sequence analyses on amplified small-subunit rRNA genes. The GeneChip (Affymetrix Corporation) contained 31,179 20-mer oligonucleotides that were complementary to a subalignment of sequences in the Ribosomal Database Project (RDP) (B. L. Maidak et al., Nucleic Acids Res. 29:173-174, 2001). The chip and standard Affymetrix software were able to correctly match small-subunit ribosomal DNA amplicons with the corresponding sequences in the RDP database for 15 of 17 bacterial species grown in pure culture. When bacteria collected from an air sample were tested, the method compared favorably with cloning and sequencing amplicons in determining the presence of phylogenetic groups. However, the method could not resolve the individual sequences comprising a complex mixed sample. Given these results and the potential for future enhancement of this technology, it may become widely useful.

This phenomenon might be explained by the co-occurrence of translocations in cells that also contain dicentrics, in which case translocations would be eliminated as a by-product of selection against dicentrics. Alternatively, a fraction of translocations may themselves be lethal. Here we describe our initial approaches to develop mathematical models to test whether the decline in translocation frequencies results from the first, the second, or a combination of these two possibilities. The models assumed that all chromosome exchanges were simple, i.e., were comprised of dicentrics as well as one-way and two-way translocations. Complex aberrations (three or more breaks in two or more chromosomes) were not modeled, nor were fragments or intrachromosomal exchanges (rings, inversions). We tested the models using Monte Carlo simulations, and then we fitted the models to data describing chromosome aberration frequencies induced by a single acute in vitro exposure to 137Cs g rays in human peripheral blood lymphocytes from two donors. Chromosome painting was used to enumerate translocations and dicentrics from 2 to 7 days after exposure. Our results indicate that in donor no. 2, the decline in translocation frequencies occurs as a by-product of selection against dicentrics. However, in donor no. 1, whose cells appeared more radiosensitive than cells from donor no. 2, up to 40% of the one-way translocations may themselves be lethal at high doses, although calculations indicate that two-way translocations do not cause lymphocyte mortality. Individual variation in the probability that translocations are lethal to cells appears to be important, and one-way translocations appear to be lethal more often than two-way translocations. Within the limits of these models, these findings indicate that both postulated mechanisms, i.e. inherent lethality and selection against dicentrics in the same cells, contribute to the loss of both one-way and two-way translocations.

I. Mechanistic insights. AN - 71582713; 11937636 AB - Base excision repair (BER) is a multistep process involving the sequential activity of several proteins that cope with spontaneous and environmentally induced mutagenic and cytotoxic DNA damage. Quantitative kinetic data on single proteins of BER have been used here to develop a mathematical model of the BER pathway. This model was then employed to evaluate mechanistic issues and to determine the sensitivity of pathway throughput to altered enzyme kinetics. Notably, the model predicts considerably less pathway throughput than observed in experimental in vitro assays. This finding, in combination with the effects of pathway cooperativity on model throughput, supports the hypothesis of cooperation during abasic site repair and between the apurinic/apyrimidinic (AP) endonuclease, Ape1, and the 8-oxoguanine DNA glycosylase, Ogg1. The quantitative model also predicts that for 8-oxoguanine and hydrolytic AP site damage, short-patch Polbeta-mediated BER dominates, with minimal switching to the long-patch subpathway. Sensitivity analysis of the model indicates that the Polbeta-catalyzed reactions have the most control over pathway throughput, although other BER reactions contribute to pathway efficiency as well.

AN - 71596596; 11944981 AB - In the course of large-scale mutagenesis studies, we discovered a mutant that provides a new mouse model for human autosomal recessive polycystic kidney disease. Animals homozygous for this mutation, T(2;10)67Gso, present evidence of grossly cystic renal and hepatic tissue at birth and a limited survival time of 3-4 days. The recessively expressed phenotype is associated with inheritance of a reciprocal translocation involving mouse chromosomes 2 and 10. Here we describe the pathology and phenotype of this new mutation. The mapping of the chromosomal breakpoint to the 1.0-cM critical region defined for another mouse autosomal recessive polycystic kidney disease model, juvenile congenital polycystic kidney disease (jcpk), led us to undertake the complementation testing that confirmed T(2;10)67Gso and jcpk are allelic. Because of the strong resemblance between the phenotype associated with these mouse mutations and early childhood polycystic kidney disease, and because of advantages offered by reciprocal translocations for gene mapping and cloning, T(2;10)67Gso should prove a valuable asset for studies concerning this fatal disease.

The maximum fault slip occurs along a pair of low-angle normal faults that have caused significant tectonic denudation of the Tethyan Sedimentary Sequence, resulting in juxtaposition of weakly metamorphosed Paleozoic rocks and Tertiary sedimentary rocks in the hanging wall over amphibolite-facies mylonitic schist, marble, gneisses, and variably deformed leucogranite bodies in the footwall. The footwall of the detachment fault system records a late Miocene intrusive event, in part contemporaneous with top-to-the-west ductile normal shearing. The consistency of the mean shear direction within the mylonitic footwall rocks and its correlation with structurally higher brittle normal faults suggest that they represent an evolving low-angle normal-fault system. (super 40) Ar/ (super 39) Ar data from muscovite and biotite from the footwall rocks indicate that it cooled below 400 degrees C by ca. 9 Ma. Consideration of the original depth and dip angle of the detachment fault prior to exhumation of the footwall yields total slip estimates between 66 and 35 km across the Gurla Mandhata detachment system. The slip estimates and timing constraints on the Gurla Mandhata detachment system are comparable to those estimated on the right-slip Karakoram fault system, to which it is interpreted to be kinematically linked. Moreover, the mean shear-sense direction on both the Karakoram Fault and the Gurla Mandhata detachment system overlap along the intersection line between the mean orientations of the faults, which further supports a kinematic association. If valid, this interpretation extends previous results that the Karakoram Fault extends to mid-crustal depths.

Interpretation of seismic velocities and amplitudes is based on theories of fluid-saturated and partially saturated rocks that have been available since the 1950s. Here we present a new synthesis of the same physical concepts that uses compressional-wave velocities together with shear-wave velocities in a scheme that is much simpler to understand and apply yet yields detailed information about porosity and fluid saturation magnitudes and spatial distribution. The key idea revolves around the fact that the density and the Lame elastic parameter lambda are the only two parameters determining seismic velocities that also contain information about fluid saturation. At low enough frequencies, Gassmann's well-known equations show that the shear modulus is independent of the fluid saturation level. We use these facts to construct saturation-proxy and data-sorting plots from seismic velocity data. The new method does not require reflectivity data, although it can use such information if available. The method can therefore be applied to a wide range of source receiver configurations, including seismic reflection profiling (surface to surface), vertical seismic profiling (well to surface), and cross-well seismic transmission tomography (well to well) since availability of reflection data is not a requirement.

Sediments were characterised using on-board visual description, smear-slides analyses, grain-size composition and magnetic susceptibility (MS) records. Five tephra marker layers, identified as Ko, TR, K2, K3 and K4, were distinguished using petrological, mineralogical and geochemical analyses. Age models were developed by comparing lithological units, tephra stratigraphy and MS records with oxygen isotope curves and with records of biogenic CaCO (sub 3) , opal content, and sediment grain-size composition in three AMS radiocarbon dated Okhotsk cores. This chronological framework allowed us to investigate climate control over the sedimentation regime and productivity, and to clarify the formation times of the lithological and tephra units. The data show that sediment MS variations in the south-eastern area of the glacial Okhotsk Sea arose primarily from volcanic material input. The sedimentation in all other parts of the sea was mainly controlled by the supply of terrigenous material. The cores show a tight correlation between MS, sediment grain size and climate change in the Okhotsk Sea: coarse sediments with a high MS were accumulated during the cold period-oxygen isotope stages (MIS) 2, 4, 6; fine sediments with a low ice-rafted debris (IRD) content and MS were formed in the warm isotope stages. According to the oxygen isotope stratigraphy and radiocarbon data, the Ko, TR, K2, K3 and K4 tephra were deposited at 7.7, 8.0, 26.0 kyr BP, in MIS 4 about 60-70 kyr ago, and near MIS 5.4, respectively. Comparison of tephra mineralogy, petrology, spatial distributions and ages with the history of Kurile-Kamchatka volcanism allows us to identify likely candidates for the tephra source eruptions. The combined use of MS records, tephrochronology and lithological unit sequences provides a detailed basis for Okhotsk Sea sediment stratigraphy.

The first -- oblique convergence between the Nazca and South American plates -- has produced a component of sinistral deformation in the Andean region. Examples include counterclockwise rotation of late Cenozoic intercordilleran basins (e.g., Ayacucho, ca. 9 to 7 Ma), sinistral transtension that partially facilitated emplacement of the Cordillera Blanca batholith (ca. 8 Ma), and oblique sinistral slip along large-scale, active normal faults (e.g., Cordillera Blanca detachment fault, Quiches fault). The second boundary condition involved flattening of the Nazca slab, which at the latitudes studied here (8-13 degrees S), was primarily caused by subduction of the aseismic (hotspot) Nazca Ridge. Plate reconstruction shows that the Nazca Ridge, the leading edge of the flat slab, subducted under the Cordillera Blanca region at ca. 5 Ma, a time coincident with both the cessation of arc magmatism and the onset of detachment faulting. We propose that lithospheric buoyancy from the subducted ridge triggered extensional collapse of pre-thickened continental crust. Detachment faulting nucleated in crust thermally weakened by emplacement of the Cordillera Blanca batholith, the penultimate magmatic event prior to slab flattening. The Andean region is thus dominated by transcurrent and extensional deformation, with contraction isolated to the trench and sub-Andean regions. Many questions remain, such as how slab flattening, and attendant plate coupling, might have affected the partitioning of oblique plate convergence in the overriding plate.

A significant component of this dextral shear is accommodated along the Owens Valley-White Mountains fault system. A recently published kinematic model for the ECSZ suggests that since approximately 1.7 Ma, 15-40% of Owens Valley fault slip was captured by the Deep Springs normal fault and transferred eastward to the Fish Lake Valley fault zone. Based on this model, 1.0-2.8 mm/yr of Owens Valley fault slip continues northward along the White Mountains fault zone (WMFZ) (Lee et al., 2001). New geologic mapping, geomorphic, and geochronologic investigations along the WMFZ shed light on its Quaternary dextral fault slip history and allow us to test this kinematic model. The WMFZ is composed of a network of NNW-striking right lateral strike-slip faults and NNE-striking, primarily W-dipping normal faults that bound the western side of the White Mountains. This fault zone cuts Quaternary coarse- to fine-grain alluvial fan deposits interbedded with tuffaceous sand, partially welded tuff, and Bishop ash. Based on alluvial fan surface morphology, such as terrace height, presence or absence of bar and swale morphology, degree of fan dissection, and degree of desert pavement development, we have identified three Quaternary alluvial fan surfaces of distinct ages. Tectonic geomorphic features such as linear fault scarps, closed depressions, ponded alluvium, offset alluvial fans, deflected drainages, and shutter ridges indicate that dextral faults cut these alluvial surfaces. Drainages and shutter ridges show offsets that range from 5 to 370 meters. 10Be cosmogenic radionuclide (CRN) dating methods used on in situ boulders demonstrate that the age of the oldest fan surface is approximately 200 ka. Maximum offset of this oldest fan surface is approximately 370 m, yielding a late Pleistocene slip rate of approximately 1.8 mm/yr. Therefore, the slip rate estimate determined in this study is consistent with the model proposed for the WMFZ.

During the 1906 San Francisco earthquake, the ground ruptured along the northeastern edge of the Vedanta marsh where historical offset measurements near the site were about 5 m. Five trenches were excavated across the fault during the 2001 field season. The main fault zone consists of a 2-m-wide zone of upward-branching fault splays within the marsh stratigraphy. A secondary fault zone located 5 m to the east juxtaposes older sediment (>25 ka) against colluvium in apparent normal separation. We exposed a 4 m section consisting of six major peat layers interbedded with fluvial gravel and marsh clay and silt that interfinger eastward with colluvial gravels. A clear, vertical transition from predominantly fine-grained marsh deposits to coarse clastic sediment occurs at a depth of approximately 1 m and is probably caused by historical logging and landuse changes in the watershed. AMS radiocarbon dating of more than 70 samples of peat, macrofossils, and charcoal collected throughout the section indicate that the base of the exposed section is about 2500 yr B.P. We recognize evidence for up to ten earthquakes using outward-splaying, upward fault terminations and fissure fills. The 1906 earthquake ruptures a portion of the upper gravel and a possible late 19th century road fill. Deformation within each of the laterally correlative, upper three peat layers deposited about 300, 700, and 1100 yr B.P. exposed in all the trenches provide age constraints on the timing of four pre-1906 earthquakes. Earlier events were exposed in the one deep excavation and are confined between the section dated to approximately 1200 to 2500 yr B.P. An offset channel traced to the west side of the fault and a buried tree are future targets of study, as they provide excellent piercing points to determine slip of paleoearthquakes. Extension and refinement of the record of earthquakes at this site is anticipated with additional field exploration and continued radiocarbon dating and analyses.

These previous studies failed to fully recognize the interplay of slope failure mechanisms because they lacked detailed field characterization of the cliff. Since construction, the cliff edge has retreated a total of 16 meters to within 6 meters of a building corner. The most recent and one of the largest retreats occurred in 1997-1998. The increased threat of this condition motivated our investigation. Our analysis of historical photographs and topographic maps shows that movement rates are episodic and not evenly distributed over time or location. The most recent failures have occurred in apparent association with large El Nino events: e.g. 2 years following the 1986-1987 El Nino and, again, during the very strong 1997-1998 event. These re-occurring periods of heavy rainfall and attendant higher levels of ground water facilitate slope instability. An innovation of our investigation was to use fixed-ropes to examine the geologic structures exposed in the near-vertical cliff face. Excavations along the base of the cliff previously indicated that the sedimentary rock was cut by a system of NE-trending faults and other associated joints and fractures. Large diameter borings located between the complex and cliff-edge failure zone further exposed a system of open fractures and clay seams trending beneath the buildings. We conclude that slope instability is due to: (1) block slides along gently seaward-dipping clay seams; (2) shallow slumping in the upper 17 meters of soils; (3) topple blocks and rock falls in the conglomerate middle cliffs along numerous near-vertical faults; and (4) wave erosion of the talus slope along the base of the cliff. The interaction of these different mechanisms, enhanced by infiltrating water from natural and other sources, controls the rate of landslides and bluff edge retreat. Previous investigations often concluded with a focus on average retreat rates, which, in light of the episodic retreat process, are very misleading. This investigation shows that the collection and examination of more detailed field data can greatly influence conclusions and lead to a more accurate slope-stability assessment.
