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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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