AN - 734144658; 19921903 AB - A sample of high-level radioactive tank waste was characterized to provide a basis for developing a waste simulant. The simulant is required for pilot-scale testing of pretreatment processes in a nonradiological facility. The waste material examined was derived from the bismuth phosphate process, which was the first industrial process implemented to separate plutonium from irradiated nuclear fuel. The bismuth phosphate process sludge is a complex mixture rich in bismuth, iron, sodium, phosphorus,silicon, and uranium.The form of phosphorus in this particular tank waste material is of specific importance because that is the primary component (other than water-soluble sodium salts) that must be removed from the high-level waste solids by pretreatment. This work shows unequivocally that the phosphorus in this waste material is not present as bismuth phosphate. Rather, the phosphorus appears to be incorporated mostly into an amorphous iron(III) phosphate phase. The bismuth in the sludge solids is best described as BiFeO3. The behavior of phosphorus during caustic leaching of the bismuth phosphate process sludge solids is also discussed.

The reaction network was calibrated using data from the 2002 field experiment, after which it was applied without additional calibration to field experiments performed in 2003 and 2007. The robustness of the model specification is significant in that (1) the 2003 biostimulation field experiment was performed with 3 times higher acetate concentrations than the previous biostimulation in the same field plot (i.e., the 2002 experiment), and (2) the 2007 field experiment was performed in a new unperturbed plot on the same site. The biogeochemical reactive transport simulations accounted for four terminal electron-accepting processes (TEAPs), two distinct functional microbial populations, two pools of bioavailable Fe(III) minerals (iron oxides and phyllosilicate iron), uranium aqueous and surface complexation, mineral precipitation and dissolution. The conceptual model for bioavailable iron reflects recent laboratory studies with sediments from the UMTRA site that demonstrated that the bulk ([not, vert, similar]90%) of initial Fe(III) bioreduction is associated with phyllosilicate rather than oxide forms of iron. The uranium reaction network includes a U(VI) surface complexation model based on laboratory studies with Rifle site sediments and aqueous complexation reactions that include ternary complexes (e.g., calcium-uranyl-carbonate). The bioreduced U(IV), Fe(II), and sulfide components produced during the experiments are strongly associated with the solid phases and may play an important role in long-term uranium immobilization.

2012-084806 AB - The purpose of this work is to identify the mechanisms that govern the removal of carbon tetrachloride (CT) during soil vapor extraction (SVE) by comparing numerical and analytical model simulations with a detailed data set from a well-defined intermediate-scale flow cell experiment. The flow cell was packed with a fine-grained sand layer embedded in a coarse-grained sand matrix. A total of 499 mL CT was injected at the top of the flow cell and allowed to redistribute in the variably saturated system. A dual-energy gamma radiation system was used to determine the initial NAPL saturation profile in the fine-grained sand layer. Gas concentrations at the outlet of the flow cell and 15 sampling ports inside the flow cell were measured during subsequent CT removal using SVE. Results show that CT mass was removed quickly in coarse-grained sand, followed by a slow removal from the fine-grained sand layer. Consequently, effluent gas concentrations decreased quickly at first, and then started to decrease gradually, resulting in long-term tailing. The long-term tailing was mainly due to diffusion from the fine-grained sand layer to the coarse-grained sand zone. An analytical solution for a one-dimensional advection and a first-order mass transfer model matched the tailing well with two fitting parameters. Given detailed knowledge of the permeability field and initial CT distribution, we were also able to predict the effluent concentration tailing and gas concentration profiles at sampling ports using a numerical simulator assuming equilibrium CT evaporation. The numerical model predictions were accurate within the uncertainty of independently measured or literature derived parameters. This study demonstrates that proper numerical modeling of CT removal through SVE can be achieved using equilibrium evaporation of NAPL if detailed fine-scale knowledge of the CT distribution and physical heterogeneity is incorporated into the model. However, CT removal could also be fit by a first-order mass transfer analytical model, potentially leading to an erroneous conclusion that the long-term tailing in the experiment was kinetically controlled due to rate-limited NAPL evaporation.

Numerical model simulations have been compared with detailed data sets from intermediate-scale flow cell experiment. The flow cell was packed with configurations of fine-grained sand layers embedded in coarse-grained sand matrices. CT was injected at the top of the flow cell from single or multiple sources and allowed to redistribute in the variably saturated systems. A sloping water table, resulting in water movement in the saturated zone, was imposed near the bottom. A dual-energy gamma radiation system was used to determine CT saturations profiles and CT gaseous concentrations at the outlet of the flow cell and 15 sampling ports inside the flow cell were measured during subsequent CT removal using SVE. Several SVE schemes were used, including targeted removal near the water table to prevent CT vapors to migrate from the gas phase into the capillary fringe. Results show that CT mass was removed relatively quickly in the coarse-grained sand, followed by a slow removal from the fine-grained sands. The observed concentration tailing was mainly due to diffusion from the fine-grained sand layer to the coarse-grained sand zone. Comparison of experimental and numerical simulation results demonstrate that proper numerical modeling of CT removal through SVE can be achieved using equilibrium evaporation as long as detailed fine-scale knowledge of the CT distribution and physical heterogeneity is incorporated into the model. However, it was shown for one of the experiments that CT removal could also be accurately fitted by a first-order mass transfer analytical model. This potential ambiguous result might potentially lead to an erroneous conclusion that the long-term tailing in the experiment was kinetically controlled due to rate-limited NAPL transfer into the gaseous phase.

Subsequent groundwater monitoring has revealed that the initial assumptions regarding a) uranium inventories in the subsurface, and b) processes that distribute those inventories via environmental pathways, were inaccurate. For the current plume, estimates suggest a contaminated groundwater volume of approximately 1,000,000 m (super 3) that contains a dissolved mass of uranium typically in the range 60 approximately 80 kg. These parameters have remained relatively constant since 2002, despite major surface source removal actions, discharge of contaminated groundwater to the Columbia River, and groundwater withdrawal at a water supply well. Estimates for groundwater discharge to the river, based on a 3-D groundwater flow model, suggest a maximum rate of 315 m (super 3) /m (sub shore) /yr under current river conditions. Uranium flux via this discharge can be bracketed by applying a range of typical average concentrations for uranium in the plume, and suggest a likely flux of 20 approximately 50 kg/yr, with another 10 kg/yr being removed via the water supply well. Estimates have also been developed for the inventory of contaminant uranium in various subsurface regions, using sediment and water samples that cover the vadose zone, the zone through which the water table rises and falls, and the uppermost hydrologic unit within the unconfined aquifer. The largest inventory is associated with the vadose zone beneath former disposal facilities and may reach several thousand kilograms, which is a relatively small fraction of the amount historically disposed. Contamination is concentrated in the vadose zone beneath former disposal facilities, but may also be widespread in sediment through which the water table has fluctuated, especially during earlier 300 Area operating conditions. How much of the inventory is available for migration under current conditions to resupply the groundwater plume is a principal uncertainty in the conceptual model. However, as mass balance estimates for the plume become more refined and defensible with field data, limits can be placed on the resupply via downward migration from the vadose zone, thus providing key information for evaluating remediation alternatives.

During SVE, contaminated soil gas is removed from the subsurface. This process removes contamination from portions of the vadose zone readily accessible to induced soil gas movement. Some portions of the vadose zone are more slowly remediated due to low induced soil gas flow, large vapor diffusion distances, and/or presence of NAPL. In particular, contamination within low permeability portions of the vadose zone represent potential zones of persistent contamination that need to be considered in SVE closure and transition decisions. There are several methods to estimate the impact of persistent vadose zone volatile contamination on the groundwater. The suitability of each technique depends on the site setting and associated primary transport mechanisms from the vadose zone to the groundwater. Each method requires some assumptions and some type of measurement in the vadose zone to quantify the strength of the source. Where aqueous transport dominates, contaminant transport in the vadose zone is primarily vertical (one-dimensional), the contact area of vadose zone contamination on the water table can be readily estimated, and transport across the water table can be represented simply. As vapor-phase transport becomes more important (e.g., for arid sites with low aqueous recharge), three-dimensional contaminant movement in the vadose zone may be more important, the contact area of vadose zone contamination on the water table is more difficult to estimate, and transport of contaminants across the water table includes a mass transfer resistance. Thus, when vapor-phase transport is significant, these issues should be considered in terms of computing contaminant flux to the groundwater and the resultant groundwater contaminant concentrations. Numerical modeling was applied to evaluate the factors that impact estimates of mass flux to the groundwater and the resultant groundwater concentration for persistent sources of volatile contaminants under conditions where vadose zone transport is predominantly in the vapor-phase. These results have implications in selecting appropriate transition or closure goals for SVE that are protective of groundwater.

To avoid such problems, isotopic ratio measurements of redox active metals have been used to quantify reduction and extent of immobilization where one redox state is less mobile than another. Here we present new (super 238) U/ (super 235) U results for groundwater samples from Rifle, CO, in a near-surface aquifer contaminated by earlier uranium milling operations. The U.S. Department of Energy removed the tailings pile and the upper few meters of alluvial sediment. However, residual uranium contamination remains in the groundwater. This contaminated alluvial aquifer provides an excellent natural laboratory for studying in situ bioremediation of uranium (e.g. Anderson, et al., 2003; AEM). The Winchester Experiment conducted at the Rifle Integrated Field Research Challenge Site investigated uranium reduction accompanying the injection of acetate-amended groundwater. This carbon-rich groundwater stimulates the growth of native iron-reducing bacteria, such as Geobacter sp., which reduce mobile U(VI) to immobile U(IV), enabling the in situ sequestration of aqueous uranium. We have analyzed a set of groundwater samples from the injection experiment, as well as natural background samples for (super 238) U/ (super 235) U by MC-ICP-MS using double spike methods. We observe that (super 238) U/ (super 235) U decreases steadily with time as injection and uranium reduction proceeds. As uranium concentrations decrease from nearly equal 200mu g/L to nearly equal 20mu g/L, we observe a systematic change to lower (super 238) U/ (super 235) U of nearly equal 1.00ppm. This change to lower (super 238) U/ (super 235) U is complimentary to that observed in both reduced sediments (Weyer, et al., 2008; GCA) and reduced uranium ore deposits (Bopp, et al., 2009; Geology): of opposite sense because we test the fluid rather than the sediments, and similar magnitude. Thus, measurements of (super 238) U/ (super 235) U provide a method for assessing extent of uranium reduction, which is free of the problems that hamper concentration measurements. This study provides the first demonstration of (super 238) U/ (super 235) U ratios as a tracer of the reduction and immobilization of uranium at the field scale.

As a supercritical fluid, CO (sub 2) is pumped into deep basalt, both of which react, creating stable calcite and other carbonate minerals. One potential sequestration site, the Columbia River Basalt Province (CRB), is attractive because tholeiitic basalt flows cover a total area and volume of basalt reaching 200,000 km (super 2) and 234,000 km (super 3) respectively. The optimal location to inject supercritical CO (sub 2) is between two basalt flows in the interflow zone. In the CRB, this zone is typically brecciated and highly vesicular, allowing fluid movement and reaction with the basalt. To identify and characterize interflow zones and their seals, the DOE Big Sky Regional Carbon Sequestration Partnership is conducting a basalt pilot test on the Boise White Paper Mill property at Wallula, Washington. Although the stratigraphy, geochemistry and other aspects of the CRB have a long history of study, the implications of basalt textural features as related to CO (sub 2) sequestration are less established. We present a review of breccias and other textural features in the Grande Ronde and Wanapum Formations, as observed in cores and rock cuttings from the 2009 Big Sky Basalt Pilot Well along with outcrop observations and published literature on CRB basalts in eastern Washington. We find that most reservoir-quality breccias in outcrop are pahoehoe flow tops; except for a variety of basalt/water interaction textures, few breccias are associated with flow bases. Resistivity-based image logs from the 2009 pilot well are particularly helpful in placing textures observed in core and cuttings into a flow-scale context. Image logs allow estimates of vesicle density and maximum vesicle diameter as well as direct images of brecciated areas, interior flow structures and a variety of cooling and tectonic fracture geometries and densities. These features, when integrated with other data, may allow important clues to type of flow, distance from lava source, and thickness of flow, and may provide a tool for predicting mechanical properties and vertical development of reservoirs and sequestration seals.

Soil desiccation is a promising technology under consideration at the Hanford Site to protect groundwater from recalcitrant contaminants residing in the deep vadose zone. In this technology, groundwater risk mitigation is derived from reduction of vadose zone sediment pore water associated with the contamination, which is the driving force for contaminant transport to the groundwater table. Soil desiccation is not expected to remove contamination, but leave it relatively immobilized in the vadose zone. It is therefore necessary to rely on numerical simulations to predict to what extent contaminant transport is slowed and its eventual impact on contaminant fluxes to the groundwater. To evaluate the effectiveness of this technology at a potential site, moisture content and grain-size analyses were characterized at the cm-scale using in-situ measurements, and statistical correlation was used to estimate the hydraulic properties. Simulations were then performed at cm spatial resolution to identify the extent of desiccation necessary to achieve the desired contaminant flux reduction to groundwater. Given that high-resolution simulations are computationally expensive, upscaling of hydraulic properties was performed to assess model predictions of contaminant fluxes to groundwater when characterizing heterogeneities at different spatial scales.

Such processes are pertinent to assessing risk, establishing groundwater-based cleanup objectives, and for evaluating the performance of soil vapor extraction (SVE) operations. Evaluation of long-term vapor-phase mass flux at field sites is a complex endeavor, complicated by subsurface material-property heterogeneity, non-uniform contaminant distributions, and nonideal contaminant-transport processes. The objective of this study was to evaluate the utility of SVE rebound data for characterizing the magnitudes, timescales, and temporal dynamics of mass flux associated with vadose zone contaminant sources. SVE operational data collected at the Department of Energy's Hanford site are used to illustrate the results that may be obtained from analysis of SVE rebound data.

Sodium dichromate was used as a corrosion inhibitor in the nuclear reactors and for decontamination purposes. The persistent contamination, shallow excavations, and limited deep vadose zone sampling indicate ongoing chromate flux from the vadose zone. Chromate is considered to be highly mobile in the low organic-carbon oxic vadose zone and aquifer sediments, however, a number of physical and geochemical factors, potentially affect the mobility and lead to long tailing in the dissolved concentrations. This may have implications for the long-term effectiveness of remediation options. Column leaching experiments and micro-scale characterization on sediments from 5 locations of vadose zone contamination illustrate different transport behaviors. The majority of the chromate is removed in the first pore volume of saturated flow in most samples, but variability of the tailing is related to factors such as the co-disposal of acidic waste, iron content, and sediment lithology. The pH of the initial sediment leach is a good predictor of the extent of tailing with low pH sediments exhibiting longer tails. Sediments from an acid-disposal facility contained a large fraction of tightly-bound chromium. This chromium was found to be mixed Cr(VI)/Cr(III) and iron was found as mixed Fe(II)/Fe(III) by X-ray photoelectron spectroscopy. Extensive reduction to Cr(III) limits mass flux from this source. Preliminary data from samples collected in the vicinity of a major contaminant source showed initial alkaline pH and only minor tailing.

In many cases, the bonding arrangement between cations and ligands (oxygen) are similar and bond lengths are identical. For example, d (super 29) Si MAS-NMR measurements indicate no significant difference between Si-O bonds in conjugate crystalline and glassy materials. In addition, there are reported cases in which measured dissolution rates of "mineral glass" and crystalline materials (e.g., feldspar glass and crystals) are indistinguishable from each other. Despite these similarities the mechanisms that govern dissolution are different for amorphous and crystalline species, especially as equilibrium is approached. Equilibrium with respect to the rate-limiting phase can be approached experimentally by adding either dissolved Al or Si (or both) to solution. Based on our work on alkali-rich (Na>Al+ (super iv) B) boroaluminosilicate glass and feldspar crystals, we will show that, on the one hand, crystalline dissolution is governed by the presence or absence of etch pits. In contrast, glass dissolution is controlled by surface reaction control at far from equilibrium settings, and by ion-exchange kinetics near equilibrium. For situations in which the borosilicate glass is phase separated, dissolution of the sodium metaborate (Na (sub 2) B (sub 4) O (sub 7) ) domains is the principal mechanism by which glass components are released to solution. In all of the above cited cases, as the system approaches equilibrium with respect to the rate-limiting secondary phase, dissolution rates typically show a non-linear response to the saturation state of the solution. These data indicate that linear Transition-State Theory (TST) models are likely inappropriate for most silicate materials (crystalline or amorphous). As well, the data demonstrates that rate models used to describe the dissolution of crystalline substances cannot be applied to models of glass dissolution.

In laboratory experiments, CRB basalts react with formation water and supercritical CO (sub 2) to precipitate carbonates, thus adding a potential mineral trapping mechanism to the dissolution and hydrodynamic trapping mechanisms of conventional sedimentary sequestration reservoirs. The DOE's Big Sky Regional Carbon Sequestration Partnership has completed drilling the first pilot well to a depth of 1253 m on the Boise White Paper Mill property at Wallula, Washington. This well is being tested for reservoir capacity and seal integrity in the deeper basalt section. If characterization results are favorable, 1000 metric tons of food-grade CO (sub 2) will be injected and studied over a multi-year period to obtain field data on in-situ mineralization. Initiation of drilling was preceded by acquisition and processing of a 6.5 km, five line multi-component 2D seismic swath. The resulting migrated P-P data imaged a succession of approximately 2400 m of unfaulted basalt, suitable for wellbore characterization and testing. Subsurface stratigraphy at the pilot well was established through XRF geochemistry, tied to wireline logs and petrographic data from rotary sidewall cores and well cuttings. The Wanapum Formation contains numerous porous reservoir intervals, but few thick seal intervals. The Grand Ronde Formation contains more numerous containment intervals, but fewer porous flow tops. The new wellbore data, as integrated with data from outcrop and hydrocarbon exploration wells are consistent with the presence of a large Grand Ronde lava lake in the Pasco Basin. These new data are critical for developing an understanding of regional reservoir heterogeneity and seals of this important but unconventional sequestration target.

The chosen seeding strategy (one of many possible scenarios) can restore global averages of temperature, precipitation and sea ice to present day values, but not simultaneously. The response varies nonlinearly with the extent of seeding, and geoengineering generates local changes to important climatic features. The global tradeoffs of restoring ice cover, and cooling the planet, must be assessed alongside the local changes to climate features.

The objective of this research was to determine the effect of sulfuric acid and ammonium sulfate coatings on the ability of these mineral dust surrogates to nucleate ice in an environment where particles realistically compete for water vapor. Coated ATD particles required higher saturations at all temperatures considered, from -20 to -45 degree C, than did identical uncoated particles. Freezing of coated particles often required saturations approaching those for the homogeneous freezing of aqueous solutions of the coating material alone. Less pronounced effects were found for illite, although the presence of a coating consistently increased the saturation or decreased the temperature required for ice formation. Analysis of ice residue at the single particle level suggests that the first coated particles to freeze had thinner or incomplete coatings when compared to particles that froze later in the expansion. This observation highlights a need to verify coating properties since an assumption of homogeneity of a group of coated aerosols may be incorrect. The increase in saturation ratio for freezing suggests that gas-phase uptake of sulfates, a large fraction of which are due to anthropogenic emissions, will reduce the ice and mixed-phase cloud formation potential of atmospheric ice nuclei.

The flows of the Columbia River Basalt Group (CRBG) have a combined thickness of approximately 5,000 m and cover an area of 168,000 sq km. Brecciated interflow zones within the CRBG may have potential for geologic storage of anthropogenic CO (sub 2) . Laboratory experiments indicate a rapid chemical reaction of basalts with both water-bearing supercritical CO (sub 2) and the slightly acidic formation fluids containing dissolved CO (sub 2) to precipitate stable carbonate minerals, providing encouraging evidence for the potential of basalt-based CO (sub 2) sequestration to permanently trap injected CO (sub 2) via mineralization as well as more universal hydrodynamic and dissolution trapping mechanisms. DOE's Big Sky Regional Carbon Partnership is currently investigating the suitability of basalt reservoirs underlying the Boise White Paper mill near Wallula, Washington for safe, secure CO (sub 2) storage. The newly drilled pilot well is providing invaluable subsurface data in this part of the Columbia Basin. Combining new wellbore, seismic, and outcrop data with public data from existing water wells, gas exploration wells, airborne magnetic surveys, geothermal, structural, and basemap data via GIS, the authors present a preliminary evaluation of the local interflow zones with potential as storage intervals, an approximation of their potential CO (sub 2) storage capacity, and a discussion of the implications these new data bring to light regarding the stratigraphy and heterogeneity of the basalts at the Wallula site. This work provides the basis for a two- and three-dimensional visualization environment as well as a GIS-based decision support tool for project researchers and managers.

Long term geologic storage of CO (sub 2) captured from large stationary emission sources has the potential to significantly reduce the amount released into the atmosphere. In order to move forward with sequestration technology, various testing must be performed to predict the outcome of subsurface CO (sub 2) injections and to ensure successful storage with low environmental impact. Such testing includes iterative modeling of reactive transport processes. The efforts to gather data needed to perform these simulations can be labor and time intensive, and often unfruitful. A wiki-based rock properties catalog is currently being developed and populated with easily accessible data in order to shorten the time required to obtain parameters for model simulations, particularly for sites where characterization data are limited. This catalog will include geochemical, geophysical, and geomechanical rock property data. This offers a new, web accessible tool for modelers to more easily find key data such as porosity, permeability, mineral volume fractions, and associated reference information for different formations and rock types. With the ability to continually add new data the catalog is expected to expand over time and to provide a vital resource that greatly facilitates modeling efforts. With data collection for simulations being more timely and efficient, we may expect a wider range of scenarios and sites to be efficiently evaluated, thus increasing our ability to make a difference in global atmospheric emissions of anthropogenic CO (sub 2) .

The purpose of this study is to evaluate the utility of temperature data in comparison with Br tracer data to quantify the three-dimensional hydraulic conductivity distribution at the Integrated Subsurface Field Research Challenge (IFRC) Site in the 300 Area of the U.S. Department of Energy Hanford Site along the Columbia River in southeast Washington State. A field experiment was conducted in March 2009, in which a solution with a temperature of 9 degrees C and Br concentration of about 100 mg/L was injected into the aquifer through an injection well for 9 hours with a flow rate of 16.3 m (super 3) /hr. The background groundwater temperature is about 16.8 degrees C. After fluid injection, the groundwater temperature was measured at different depths in 28 wells and the groundwater was also sampled from 35 wells for Br measurement. For Br sampling, only three cluster wells were screened at different depths while all other wells were screened over the entire saturated depth. Thus, most of the Br concentrations were depth-mixed. Groundwater flow simulation was carried out with the MODFLOW code, while heat and Br tracer transport simulation was conducted with the MT3DMS code under the assumption of constant fluid density and viscosity. The inverse code PEST was employed to help calibrate the flow and transport model. The simulation results show that the groundwater head data alone are insufficient to constrain the hydraulic conductivity distribution, especially because the Hanford aquifer is highly permeable with the hydraulic conductivity in the range of 7000 m/day. While the Br tracer data are very important to improving the estimation of hydraulic conductivity, continuous Br data in 3D are expensive to acquire and not available at the Hanford IFRC site. The temperate data are shown to be a cost-effective proxy for conservative solute tracers such as the Br tracer.

Based on established separation processes involving co-precipitation, solvent extraction, and ion-exchange and extraction chromatography, we have optimized a proposed sequence of separation steps to allow for the timely quantification of analytes of interest. We have recently evaluated this scheme using an irradiated sample to examine the adequacy of separations for measurement of desired analytes by gamma spectrometry.

Diurnal trends in MeHg production, bacterial demethylation, photo-demethylation, and transport processes (including diffusion and advection) have been identified in some wetlands, however, the magnitude and relative importance of each process in mediating surface-water MeHg concentrations are not well known. Temporal variation in aqueous MeHg concentration likely impacts the bioaccumulation of MeHg into the base of the aquatic food chain, and may challenge regulatory efforts designed to mitigate MeHg exports from point and non-point sources. Surface-water MeHg concentration was monitored in two agricultural wetland settings (wild-rice and white-rice fields) over a 24-hour period within the Yolo Bypass Wildlife Area, California using a combination of in situ optical sensors and surface-water samples. In the wild-rice field (sampled at 12 cm depth of 25 cm water column), MeHg concentrations doubled from approximately 1 ng/L to approximately 2 ng/L over the nighttime hours and returned to approximately 1 ng/L during the daylight hours, however in the white-rice field (sampled at 10 cm depth of 20 cm water column) MeHg concentration (0.73 + or - 0.08 ng/L) did not vary significantly during the 24-hour period. Similar trends were observed when MeHg data were expressed as a percentage of total Hg; both wetland habitats exhibited similar levels ( approximately 20% MeHg) following the nighttime period but the wild-rice field declined to approximately 10% in the early evening. Field parameters measured in situ (solar radiation, pH, dissolved oxygen, and temperature) exhibited large diurnal trends in both wetlands, whereas optical proxies for dissolved organic matter (DOM) composition mirrored the fluctuations in MeHg concentration and %MeHg, with a strong diurnal trend in the wild-rice wetland and no apparent trend in the white-rice wetland. These results suggest a unique link between DOM photo-reactivity and photo-demethylation in these wetlands. Monitoring efforts designed to characterize daily and longer-term loads of MeHg within and from agricultural wetlands such as rice fields should include a diurnal component.

The distribution of this formation class is such that, coupled with their very large capacities, DSFs likely represent the bulk of the resource for CO (sub 2) capture and geologic storage (CCS) undertaken as part of future societal efforts to address climate change. However, beyond their potential for storage of various waste materials, few other uses currently exist for these DSFs or their largely non-potable waters. In the U.S., waters with total dissolved solids (TDS) below 10,000 mg/L cannot be used for CCS because they fall below this minimum salinity threshold set by the statutes governing CO (sub 2) injection. Preliminary analysis suggests that low TDS waters may account for over 300 billion tons of potential storage capacity, much of it in areas where there is little existing demand for these waters, and sometimes in places where there are few other storage options. In such cases, potential CCS operators may choose to petition for exemptions to de minimus TDS rules if these waters are also unlikely to be used in the future. At the same time, climate models now suggest an increased likelihood of water stress in certain areas of the U.S.. Desalination plants are being built at an increasing rate, with total operational capacity up 41 percent between 2000 and 2005, to augment water supplies in areas facing scarcity concerns. As growing populations and demand outstrip freshwater supplies, and as aquifer drawdown rates begin to exceed recharge rates by increasing margins, these drivers may be pushing society toward a future in which the marginal and lower quality waters present in these candidate DSFs may also be valued as potential supply resources. Quantitative estimation of the impacts of this type of co-optimization on the available geologic storage capacity will be presented for case studies in the Rocky Mountains and Southwest U.S. regions. These will be used to illustrate the importance of a region-specific approach to resource allocation, and to support a discussion of the broader technical and policy implications of competing demands for the nation's geologic CO (sub 2) storage resource.

T. Pardee's (1942, GSA Bulletin, v. 53, p. 1569-1600) original interpretation and subsequent regional mapping by Smith (2006, Quat. Res., v. 66, p. 311-322). Hydraulic modeling of Lake Missoula outflow events (Alho et al., this meeting) shows that lake silt sections, e.g., Ninemile, dated by OSL at 15 cal ka (Hanson et al., 2009, CANQUA meeting abstracts), would not survive the erosive effects of high-energy outflows. This newly discovered timing for the largest late Pleistocene megafloods is consistent with OSL dating of coarse-grained rhythmites at White Bluffs in the central Pasco Basin (Bjornstad et al., this meeting), and with the age of the older of two major peaks of freshwater influx to the northeast Pacific Ocean from the Columbia River system (Lopes and Mix, 2009, Geology, v. 37, p. 79-82). In contrast, the association of fine-grained rhythmites (Touchet beds), with the Mount St. Helens set S tephra ( approximately 16 ka), e.g., the Burlingame Canyon Section, plus our terrestrial cosmogenic nuclide (TCN) dating (using Cl-36) of associated ice-rafted erratics, indicate that the later (and probably smaller) flood events responsible for these deposits, correspond to the later peak of freshwater influx to the northeast Pacific, as identified by Lopes and Mix (2009). A TCN (Cl-36) date from a granite inselberg that was exhumed from its Miocene basalt cover by cataclysmic flood erosion, shows that the later flood episode also probably coincided with the recession of the upper Grand Coulee cataract into Glacial Lake Columbia near modern Grand Coulee Dam. These new results suggest more complexity to the timing of late Pleistocene megaflooding than is implied by the commonly prevailing view that the megaflooding all occurred (with 40 to 100 events) over a 2000-3000-yr interval from about 18.5 to 15 cal ka B.P. (15,500 to 12,700 C-14 ka B.P.), involving exact bed-to-bed correlations from the fine-grained rhythmically bedded sequences in the basins of glacial Lake Missoula (e.g., Ninemile) and Columbia (e.g., Sanpoil), to the Touchet Beds of south-central Washington (e.g., Burlingame), and to the Willamette Silt of northwestern Oregon.

Most of the 120-m-tall bluffs are a steep erosional escarpment of clay-silt-dominated facies of the fluvial-lacustrine, Pliocene, Ringold Formation. An exception occurs near Locke Island, where either a paleo-tributary to the Columbia River or outburst floodwaters incised a 35-m-deep paleochannel into the Ringold Formation. The since-abandoned paleochannel depression served as a depocenter for the accumulation of 17 successive slackwater rhythmites, presumably representing as many cataclysmic flood events. The thickness and number of rhythmites increases toward the axis of the paleochannel. Since the 1970's the rhythmites have been conveniently exposed along scarps of a massive, two-mile-wide landslide complex, which exactly conforms to the width of the paleochannel. Rhythmite beds overlie sharp, erosional boundaries and are characterized by normally graded beds that transition upward from horizontally laminated, medium to coarse sand to climbing-ripple cross-laminated fine to very fine sand to coarse silt. The upper portions of many rhythmites consist of draped, wavy-laminated to massive fine silt that locally have been deformed by overlying coarse sediment. Rhythmite thicknesses (ave. = 2.6 m; max. = 6.3 m) are significantly greater than Ice Age flood rhythmites observed elsewhere, perhaps due the geometry of the embayment and higher sediment load for megafloods at this location. Paleomagnetic, pedologic, and OSL-dating techniques indicate the rhythmites are of late Pleistocene age. The normal-polarity succession is interrupted atop rhythmite #13 (from base) by a calcic paleosol cut and filled with four additional rhythmites. An OSL age on sediment just below the unconformity is 21 + or - 2 cal ka, while the youngest of four rhythmites above the unconformity has an OSL age of 12 + or - 2 cal ka. Disconformably overlying the rhythmites are many meters of Holocene dune sand and loess derived primarily from remobilized megaflood and Ringold Formation deposits. A maximum age from the base of the eolian unit, from OSL, is 3.3 + or - 0.5 cal ka. Eolian deposits continue to aggrade atop the White Bluffs.

AN - 67674157; 19495862 AB - Planners are being called on to prioritize marine shorelines for conservation status and restoration action. This study documents an approach to determining the management strategy most likely to succeed based on current conditions at local and landscape scales. The conceptual framework based in restoration ecology pairs appropriate restoration strategies with sites based on the likelihood of producing long-term resilience given the condition of ecosystem structures and processes at three scales: the shorezone unit (site), the drift cell reach (nearshore marine landscape), and the watershed (terrestrial landscape). The analysis is structured by a conceptual ecosystem model that identifies anthropogenic impacts on targeted ecosystem functions. A scoring system, weighted by geomorphic class, is applied to available spatial data for indicators of stress and function using geographic information systems. This planning tool augments other approaches to prioritizing restoration, including historical conditions and change analysis and ecosystem valuation.

These contests were designed to provide researchers with a better understanding of the tasks and data that face potential end users. Access to these end users is limited because of time constraints and the classified nature of the tasks and data. In that respect, the contests serve as an intermediary, with the metrics and feedback serving as measures of utility to the end users.

Batch and flow-through dissolution experiments were conducted along with spectroscopic analyses to compare biogenic uraninite nanoparticles obtained from Shewanella oneidensis MR-1 and chemogenic UO (sub 2.00) with respect to their equilibrium solubility, dissolution mechanisms, and dissolution kinetics in water of varied oxygen and carbonate concentrations. Both materials exhibited a similar intrinsic solubility of approximately 10 (super -8) M under reducing conditions. The two materials had comparable dissolution rates under anoxic as well as oxidizing conditions, consistent with structural bulk homology of biogenic and stoichiometric uraninite. Carbonate reversibly promoted uraninite dissolution under both moderately oxidizing and reducing conditions, and the biogenic material yielded higher surface area-normalized dissolution rates than the chemogenic. This difference is in accordance with the higher proportion of U(V) detected on the biogenic uraninite surface by means of X-ray photoelectron spectroscopy. Reasonable sources of a stable U(V)-bearing intermediate phase are discussed. The observed increase of the dissolution rates can be explained by carbonate complexation of U(V) facilitating the detachment of U(V) from the uraninite surface. The fraction of surface-associated U(VI) increased with dissolved oxygen concentration. Simultaneously, X-ray absorption spectra showed conversion of the bulk from UO (sub 2.0) to UO (sub 2+x) . In equilibrium with air, combined spectroscopic results support the formation of a near-surface layer of approximate composition UO (sub 2.25) (U (sub 4) O (sub 9) ) coated by an outer layer of U(VI). This result is in accordance with flow-through dissolution experiments that indicate control of the dissolution rate of surface-oxidized uraninite by the solubility of metaschoepite under the tested conditions. Although U(V) has been observed in electrochemical studies on the dissolution of spent nuclear fuel, this is the first investigation that demonstrates the formation of a stable U(V) intermediate phase on the surface of submicron-sized uraninite particles suspended in aqueous solutions.

The intent of the research was to develop process technology to convert the bio-oil into a petroleum refinery feedstock to supplement fossil energy resources and to displace imported feedstock. The project was a cooperative research and development agreement among UOP LLC, the National Renewable Energy Laboratory and the Pacific Northwest National Laboratory (PNNL). This article is focused on the process experimentation and product analysis undertaken at PNNL. This article describes the experimental methods used and relates the results of the product analyses. A range of catalyst formulations were tested over a range of operating parameters including temperature, pressure, and flow rate with bio-oil derived from several different biomass feedstocks. Effects of liquid hourly space velocity and catalyst bed temperature were assessed. Details of the process results were presented included product yields and hydrogen consumption. Detailed analysis of the products were provided including elemental composition, chemical functional type determined by mass spectrometry, and product descriptors such as density, viscosity, and total acid number. In conclusion, this article provides an understanding of the efficacy of hydroprocessing as applied to bio-oil.

We are currently investigating the use of liquid semiconductor based betavoltaics as a way to directly convert the energy of radioactive decay into electrical power and potentially avoid the radiation damage that occurs in solid state semiconductor devices due to non-ionizing energy loss. Sulfur-35 was selected as the isotope for the liquid semiconductor demonstrations because it can be produced in high specific activity and is chemically compatible with known liquid semiconductor media.

Experiments probing neutrino properties and searching for direct evidence of dark matter require ultra-clean copper, containing the smallest possible quantities of radioactive contaminants. Important to the production of such copper is establishing the location and dispersion of contamination within the bulk material. Co-deposition of contaminants during copper electrodeposition and its relationship to nucleation and growth processes were investigated using scanning electron microscopy (SEM), laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), and secondary ionization mass spectrometry (SIMS).

Here, we compare the products of batch uranyl reduction by a collection of dissimilatory metal- and sulfate-reducing bacteria of the genera Shewanella, Geobacter, Anaeromyxobacter, and Desulfovibrio under similar laboratory conditions. Our results demonstrate that U(VI) bioreduction by this assortment of commonly studied, environmentally relevant bacteria leads to the precipitation of uraninite with an approximate composition of UO2.0, regardless of phylogenetic or metabolic diversity. Coupled analyses, including electron microscopy, X-ray absorption spectroscopy, and powder diffraction, confirm that structurally and chemically analogous uraninite solids are produced. These biogenic uraninites have particle diameters of about 2-3 nm and lattice constants consistent with UO2.0 and exhibit a high degree of intermediate-range order. Results indicate that phylogenetic and metabolic variability within delta- and gamma-proteobacteria has little effect on biouraninite structure or crystal size under the investigated conditions.

13268088 AB - Knowledge of IFT values for chemical mixtures helps guide the design and analysis of various processes, including NAPL remediation with surfactants or alcohol flushing, enhanced oil recovery, and chemical separation technologies, yet available literature values are sparse. A comprehensive comparison of thermodynamic and empirical models for estimating interfacial tension (IFT) of organic chemical mixtures with water is conducted, mainly focusing on chlorinated organic compounds for 14 ternary, three quaternary, and one quinary systems. Emphasis is placed on novel results for systems with three and four organic chemical compounds, and for systems with composite organic compounds like lard oil and mineral oil. Seven models are evaluated: the ideal and nonideal monolayer models (MLID and MLNID), the ideal and nonideal mutual solubility models (MSID and MSNID), an empirical model for ternary systems (EM), a linear mixing model based on mole fractions (LMMM), and a newly developed linear mixing model based on volume fractions of organic mixtures (LMMV) for higher order systems. The two ideal models (MLID and MSID) fit ternary systems of chlorinated organic compounds without surface active compounds relatively well. However, both ideal models did not perform well for the mixtures containing a surface active compound. However, for these systems, both the MLNID and MSNID models matched the IFT data well. It is shown that the MLNID model with a surface coverage value (0.00341 mmol/m2) obtained in this study can practically be used for chlorinated organic compounds. The LMMM results in poorer estimates of the IFT as the difference in IFT values of individual organic compounds in a mixture increases. The EM, with two fitting parameters, provided accurate results for all 14 ternary systems including composite organic compounds. The new LMMV method for quaternary and higher component systems was successfully tested. This study shows that the LMMV may be able to be used for higher component systems and it can be easily incorporated into compositional multiphase flow models using only parameters from ternary systems.

Organic carbon (OC), element carbon (EC), and total carbon (TC=OC+EC) were determined in near real-time using a Sunset semi-continuous OCEC field analyzer. The semi-empirical EC tracer method was used to derive primary organic carbon (POC) and secondary organic carbon (SOC). Diurnal variations of primary and secondary carbon were observed at T1 and T2, which resulted from boundary layer inversion and impacted by local traffic patterns. The majority of organic carbon particles at T1 and T2 were secondary. The SOC sub(TC)% (SOC%=SOC/TC100%) at T1 ranged from 0.5-93.8% with an average of 63.5 plus or minus 17.2%. The SOC sub(TC)% at T2 ranged from 9.3-98.1% with an average of 67.4 plus or minus 12.4%. The average EC to PM sub(2.5) percentage (EC sub(PM)%=EC/PM sub(2.5) 7; 100%) and OC sub(PM)% were 6.0% and 20.0% over the whole sampling time at T1. The POC to PM percentage (POC sub(PM)%) and SOC sub(PM)% were 3.7% and 16.3%, respectively at the same site. The maximum EC sub(PM)% was 21.2%, and the maximum OC sub(PM)% was 57.2% at T1. The maximum POC sub(PM)% was 12.9%, and the maximum SOC sub(PM)% was 49.7% at T1. Comparison of SOC and POC at T1 and T2 showed similar characteristics under favorable meteorological conditions, which indicated that transport from T1 towards T2 took place. Strong correlations between EC and carbon monoxide (CO) and odd nitrogen species (NO and NO sub(x)) were observed at T1. This indicated that EC had nearby sources, such as local traffic emissions. The EC/CO ratio derived by linear regression analysis, with units of mu g C/m super(3) and mu g/m super(3), respectively, was 0.004 at T1. Correlations were also seen between OC and SOC vs. the sum of oxidants, such as O sub(3) and NO sub(2), suggesting the secondary nature of carbons observed at T1.

'Inward-flux' diffusion studies were conducted in which [U(VI)] in both aqueous and solid phases was measured as a function of distance in the diffusion cell under conditions of constant concentration at the cell boundaries. A sequential extraction method was developed to measure sorbed contaminant U(VI) in the solid phase containing extractable background U(VI). The effect of sorption kinetics on U(VI) interparticle diffusion was evaluated by comparing sorption-retarded diffusion models with sorption described either as equilibrium or intraparticle diffusion-limited processes. Both experimental and modeling results indicated that (1) a single pore diffusion coefficient can simulate the diffusion of total aqueous U(VI), and (2) the local equilibrium assumption (LEA) is appropriate for modeling sorption-retarded diffusion under the given experimental conditions. Dp of 1.6-1.7 X 10-6 cm2/s was estimated in aqueous solution at pH 8.0 and saturated with respect to calcite, as relevant to some subsurface regions of the Hanford site.

AN - 733577658; 19643593 AB - A fluorescence sandwich immunoassay using high-affinity antibodies and quantum dot (QD) reporters has been developed for detection of botulinum neurotoxin serotype A (BoNT/A) using a nontoxic recombinant fragment of the holotoxin (BoNT/A-H(C)-fragment) as a structurally valid simulant for the full toxin molecule. The antibodies used, AR4 and RAZ1, bind to nonoverlapping epitopes present on both the full toxin and on the recombinant fragment. In one format, the immunoassay is carried out in a 96-well plate with detection in a standard plate reader using AR4 as the capture antibody and QD-coupled RAZ1 as the reporter. Detection to 31 pM with a total incubation time of 3 h was demonstrated. In a second format, the AR4 capture antibody was coupled to Sepharose beads, and the reactions were carried out in microcentrifuge tubes with an incubation time of 1 h. The beads were subsequently captured and concentrated in a rotating rod "renewable surface" flow cell equipped with a fiber optic system for fluorescence measurements. In PBS buffer, the BoNT/A-H(C)-fragment was detected to concentrations as low as 5 pM using the fluidic measurement approach.

AN - 67428805; 19345006 AB - The increased demand for the lanthanides in commercial products result in increased production of lanthanide containing ores, which increases public exposure to the lanthanides, both from various commercial products and from production wastes/effluents. This work investigates lanthanide (La, Ce, Pr, Nd, Eu, Gd and Lu) binding properties of self-assembled monolayers on mesoporous silica supports (SAMMS), that were functionalized with diphosphonic acid (DiPhos), acetamide phosphonic acid (AcPhos), propionamide phosphonic acid (Prop-Phos), and 1-hydroxy-2-pyridinone (1,2-HOPO), from natural waters (river, ground and sea waters), acid solutions (to mimic certain industrial process streams), and dialysate. The affinity, capacity, and kinetics of the lanthanide sorption, as well as regenerability of SAMMS materials were investigated. Going from the acid side over to the alkaline side, the AcPhos- and DiPhos-SAMMS maintain their outstanding affinity for lanthanides, which enable the use of the materials in the systems where the pH may fluctuate. In acid solutions, Prop-Phos- and 1,2-HOPO-SAMMS have differing affinity along the lanthanide series, suggesting their use in chromatographic lanthanide separation. Over 95% of 100 microg/L of Gd in dialysate was removed by the Prop-Phos-SAMMS after 1 min and 99% over 10 min. SAMMS can be regenerated with an acid wash (0.5M HCl) without losing the binding properties. Thus, they have a great potential to be used as in large-scale treatment of lanthanides, lanthanide separation prior to analytical instruments, and in sorbent dialyzers for treatment of acute lanthanide poisoning.

13268033 AB - In this study, we use solubility and drop-solution calorimetry measurements to determine the thermodynamic properties of the uranyl phosphate phases autunite, uranyl hydrogen phosphate, and uranyl orthophosphate. Conducting the solubility measurements from both supersaturated and undersaturated conditions and under different pH conditions rigorously demonstrates attainment of equilibrium and yields well-constrained solubility product values. We use the solubility data and the calorimetry data, respectively, to calculate standard-state Gibbs free energies of formation and standard-state enthalpies of formation for these uranyl phosphate phases. Combining these results allows us also to calculate the standard-state entropy of formation for each mineral phase. The results from this study are part of a combined effort to develop reliable and internally consistent thermodynamic data for environmentally relevant uranyl minerals. Data such as these are required to optimize and quantitatively assess the effect of phosphate amendment remediation technologies for uranium contaminated systems.

Demonstrations of passive RDX chemical detection at areal dosages between 16 and 90kg/cm were carried out over practical standoff ranges between 14 and 50 m. Anomaly and target detection algorithms were applied to the images to determine the effect of areal dosage and sensing distance on detection performance for target RDX. The anomaly detection algorithms included principal component analysis, maximum autocorrelation factors, and principal autocorrelation factors. Maximum difference factors and principal difference factors are novel multivariate edge detection techniques that were examined for their utility in detection of the RDX stains in the images. A target detection algorithm based on generalized least squares was applied to the images, as well, to see if the algorithm can identify the compound in the stains on the plates using laboratory reflection spectra of RDX, cyclotetramethylenetetranitramine (HMX), and 2,4,6-trinitrotoluene (TNT) as the target spectra. The algorithm could easily distinguish between the nitroaromatic (TNT) compound and the nitramine (RDX, HMX) compounds, and, though the distinction between RDX and HMX was less clear, the mean weighted residuals identified RDX as the stain on the plate. Improvements that can be made in this detection technique are discussed in detail. As expected, it was found that detection was best for short distances and higher areal dosages. However, the target was easily detected at all distances and areal dosages used in this study.

The data were generated by injecting a concentrated solution (83%) of H2O2 into a gently heated disseminator and diluting it with pure N2 carrier gas. The water vapor lines were quantitatively subtracted from the resulting spectra to yield the spectrum of pure H2O2. The results for the *n6 band strength (including hot bands) compare favorably with the results of Klee et al. (J Mol. Spectrosc. 195:154, 1999) as well as with the HITRAN values. The present results are 433 and 467 cmatm (c8 and c3% as measured at 298 and 323 K, respectively, and reduced to 296 K) for the band strength, matching well the value reported by Klee et al. (S=467 cmatm at 296 K) for the integrated band. The *n1+*n5 near-infrared band between 6,900 and 7,200 cm has an integrated intensity S=26.3 cmatm, larger than previously reported values. Other infrared and near-infrared bands and their potential for atmospheric monitoring are discussed.

AN - 734050405; 19764217 AB - Stirred-flow cell experiments were performed to investigate the kinetics of uranyl [U(VI)] desorption from a contaminated sedimentcollected from the Hanford 300 Area at the U.S. Department of Energy Hanford Site, Washington. Three influent solutions of variable pH, Ca and carbonate concentrations that affected U(VI) aqueous and surface speciation were used under dynamic flow conditions to evaluate the effect of geochemical conditions on the rate of U(Vl) desorption. The measured rate of U(VI) desorption varied with solution chemical composition that evolved as a result of thermodynamic and kinetic interactions between the solutions and sediment The solution chemical composition that led to a larger disequilibrium between adsorbed U(VI) and equilibrium adsorption state yielded a faster desorption rate. The experimental results were used to evaluate a multirate, surface complexation model (SCM) that has been proposed to describe U(VI) desorption kinetics in the Hanford sedimentthat contained complex adsorbed U(VI) in mass transfer limited domains (Lui et al. Water Resour. Res. 2008, 44, W08413). The model was modified and supplemented by including multirate, ion exchange reactions to describe the geochemical interactions between the solutions and sediment With the same setof model parameters, the modified model reasonably well described the evolution of major ions and the rates of U(VI) desorption under variable geochemical and flow conditions, implying that the multirate SCM is an effective way to describe U(VI) desorption kinetics in subsurface sediments.

These uncertainties normally are elucidated via application of global climate models, which provide information at relatively coarse spatial resolutions. Greater interest in, and concern about, the details of climate change at regional scales has provided the motivation for the application of regional climate models, which introduces additional uncertainty [Christensen et al., 2007a]. These uncertainties in fine-scale regional climate responses, in contrast to uncertainties of coarser spatial resolution global models in which regional models are nested, now have been documented in numerous contexts [Christensen et al., 2007a] and have been found to extend to uncertainties in climate impacts [Wood et al., 2004; Oleson et al., 2007]. While European research in future climate projections has moved forward systematically to examine combined uncertainties from global and regional models [Christensen et al., 2007b], North American climate programs have lagged behind.

An understanding of electron transfer pathways from dissimilatory metal-reducing bacteria (DMRB) to solid phase metal (hydr)oxides is important for understanding metal redox cycling in soils and sediments, for utilizing DMRB in bioremedation, and for developing technologies such as microbial fuel cells. Here we hypothesize that the outer membrane cytochromes OmcA and MtrC from Shewanella oneidensis MR-1 are the only terminal reductases capable of direct electron transfer to a hematite working electrode. Cyclic voltammetry (CV) was used to study electron transfer between hematite electrodes and protein films, S. oneidensis MR-1 wild-type cell suspensions, and cytochrome deletion mutants. After controlling for hematite electrode dissolution at negative potential, the midpoint potentials of adsorbed OmcA and MtrC were measured (-201 mV and -163 mV vs. Ag/AgCl, respectively). Cell suspensions of wild-type MR-1, deletion mutants deficient in OmcA (Delta omcA), MtrC (Delta mtrC), and both OmcA and MtrC (Delta mtrC-Delta omcA) were also studied; voltammograms for Delta mtrC-Delta omcA were indistinguishable from the control. When the control was subtracted from the single deletion mutant voltammograms, redox peaks were consistent with the present cytochrome (i.e., Delta omcA consistent with MtrC and Delta mtrC consistent with OmcA). The results indicate that OmcA and MtrC are capable of direct electron exchange with hematite electrodes, consistent with a role as terminal reductases in the S. oneidensis MR-1 anaerobic respiratory pathway involving ferric minerals. There was no evidence for other terminal reductases operating under the conditions investigated. A Marcus-based approach to electron transfer kinetics indicated that the rate constant for electron transfer k (sub et) varies from 0.025 s (super -1) in the absence of a barrier to 63.5 s (super -1) with a 0.2 eV barrier.

For species within one physiological state, however, distinction is far more challenging, and requires chemometrics. In the current study, we have narrowed the field of study by eliminating the confounding issues of vegetative cells as well as growth media and focused on using IR spectra to distinguish only between different species all in the sporulated state. Using principal component analysis (PCA) and a classification method based upon similarity measurements, we demonstrate a successful identification rate to the species level of 85% for Bacillus spores grown and sporulated in a glucose broth medium.

The experiment is complicated somewhat as logistics dictated that the column spent significant amounts of time in a sealed state (acting as a batch reactor). Changes accompanying a net reduction in porosity of 4% were quantified including: (1) a 25% net decrease in pores resulting from a 38% loss in the number of pores <10 (super -4) mm (super 3) in volume and a 13% increase in the number of pores of larger size; and (2) a 38% decrease in the number of throats. The loss of throats resulted in decreased coordination number for pores of all sizes and significant reduction in the number of pore pathways. Abstract Copyright (2009) Elsevier, B.V.

Since the emission inventories, transport, and turbulent mixing will directly affect predictions of total organic matter and consequently total particulate matter, our objective is to assess the uncertainties in predicted POA before testing and evaluating the performance of secondary organic aerosol (SOA) treatments. Carbon monoxide (CO) is well simulated on most days both over the city and downwind, indicating that transport and mixing processes were usually consistent with the meteorological conditions observed during MILAGRO. Predicted and observed elemental carbon (EC) in the city was similar, but larger errors occurred at remote locations since the overall CO/EC emission ratios in the national emission inventory were lower than in the metropolitan emission inventory. Components of organic aerosols derived from Positive Matrix Factorization of data from several Aerodyne Aerosol Mass Spectrometer instruments deployed both at ground sites and on research aircraft are used to evaluate the model. Modeled POA was consistently lower than the measured organic matter at the ground sites, which is consistent with the expectation that SOA should be a large fraction of the total organic matter mass. A much better agreement was found when modeled POA was compared with the sum of primary anthropogenic and biomass burning components derived from Positive Matrix Factorization (PMF) on most days, especially at the surface sites, suggesting that the overall magnitude of primary organic particulates released was reasonable. However, simulated POA from anthropogenic sources was often lower than primary anthropogenic components derived from PMF, consistent with two recent reports that these emissions are underestimated. The modeled POA was greater than the total observed organic matter when the aircraft flew directly downwind of large fires, suggesting that biomass burning emission estimates from some large fires may be too high.

In this combined method, several SWAT models with different structures are first selected; next GA is used to calibrate each model using observed streamflow data; finally, BMA is applied to combine the ensemble predictions and provide uncertainty interval estimation. This method was tested in two contrasting basins, the Little River Experimental Basin in Georgia, USA, and the Yellow River Headwater Basin in China. The results obtained in the two case studies show that this combined method can provide deterministic predictions better than or comparable to the best calibrated model using GA. The 66.7% and 90% uncertainty intervals estimated by this method were analyzed. The differences between the percentage of coverage of observations and the corresponding expected coverage percentage are within 10% for both calibration and validation periods in these two test basins. This combined methodology provides a practical and flexible tool to attain reliable deterministic simulation and uncertainty analysis of SWAT.

The physical and chemical transformations of particles aged in the outflow from Mexico City were investigated for the transport event of 22 March 2006. A detailed chemical analysis of individual particles was performed using a combination of complementary microscopy and micro-spectroscopy techniques. The applied techniques included scanning transmission X-ray microscopy (STXM) coupled with near edge X-ray absorption fine structure spectroscopy (NEXAFS) and computer controlled scanning electron microscopy with an energy dispersive X-ray analyzer (CCSEM/EDX). As the aerosol plume evolves from the city center, the organic mass per particle increases and the fraction of carbon-carbon double bonds (associated with elemental carbon) decreases. Organic functional groups enhanced with particle age include: carboxylic acids, alkyl groups, and oxygen bonded alkyl groups. At the city center (T0) the most prevalent aerosol type contained inorganic species (composed of sulfur, nitrogen, oxygen, and potassium) coated with organic material. At the T1 and T2 sites, located northeast of T0 (~29 km and ~65 km, respectively), the fraction of homogenously mixed organic particles increased in both size and number. These observations illustrate the evolution of the physical mixing state and organic bonding in individual particles in a photochemically active environment.

Meaningfully defining what constitutes a community of interacting microbial populations is not trivial, but is important for rigorous progress in the field. Important elements of research in microbial community ecology include the analysis of functional pathways for nutrient resource and energy flows, mechanistic understanding of interactions between microbial populations and their environment, and the emergent properties of the complex community. Some emergent properties mirror those analyzed by community ecologists who study plants and animals: biological diversity, functional redundancy and system stability. However, because microbes possess mechanisms for the horizontal transfer of genetic information, the metagenome may also be considered as a community property.

Here we demonstrate the use of a minimally invasive geophysical technique to monitor stimulated microbial activity during acetate amendment in an aquifer near Rifle, Colorado. During electrical induced polarization (IP) measurements, spatiotemporal variations in the phase response between imposed electric current and the resultant electric field correlated with changes in groundwater geochemistry accompanying stimulated iron and sulfate reduction and sulfide mineral precipitation. The magnitude of the phase response varied with measurement frequency (0.125 and 1 Hz) and was dependent upon the dominant metabolic process. The spectral effect was corroborated using a biostimulated column experiment containing Rifle sediments and groundwater. Fluids and sediments recovered from regions exhibiting an anomalous phase response were enriched in Fe(II), dissolved sulfide, and cell-associated FeS nanoparticles. The accumulation of mineral precipitates and electroactive ions altered the ability of pore fluids to conduct electrical charge, accounting for the anomalous IP response and revealing the usefulness of multifrequency IP measurements for monitoring mineralogical and geochemical changes accompanying stimulated subsurface bioremediation.

They are ideal for drug-delivery platforms due to their biocompatibility and biodegradability coupled with low toxicity. A variety of proteins have been used and characterized for drug-delivery systems, including the ferritin/apoferritin protein cage, plant-derived viral capsids, the small Heat shock protein (sHsp) cage, albumin, soy and whey protein, collagen, and gelatin. There are many different types and shapes that have been prepared to deliver drug molecules using protein-based platforms, including various protein cages, microspheres, nanoparticles, hydrogels, films, minirods, and minipellets. The protein cage is the most newly developed biomaterial for drug delivery and therapeutic applications. The uniform size, multifunctionality, and biodegradability push it to the frontier of drug delivery. In this Review, the recent strategic development of drug delivery is discussed with emphasis on polymer-based, especially protein-based, nanomedicine platforms for drug delivery.

It is observed that there are unique signatures clearly associated with either the sporulated or vegetative state and that vegetative cells (or cell debris) can contribute to the spore spectra. A distinct feature at ~1739 cm-1 appears to be unique to vegetative cell spectra and can also be used as an indicator of vegetative cells or cell debris in the spore spectra. The data indicate that the band arises from a lipid-soluble species such as an ester or phospholipid carbonyl bond and are consistent with it being either phosphatidyl glycerol (PG) or phosphatidylethanolamine (PE), two major classes of phospholipids found in vegetative cells of Bacillus species. A companion work discusses bands associated with the sporulated state. References: 77 references open in new window Articles that cite this article?

This work investigates the infrared spectra of eight different sporulated Bacillus bacteria. For the endospores it is observed that peaks at 1441, 1277, and 1015 cm-1 along with a distinct quartet of peaks at 766, 725, 701, and 659 cm-1 are clearly associated with calcium dipicolinate trihydrate, CaDP·3H2O. It is emphasized that the spore peaks, especially the quartet, arise from the calcium dipicolinate trihydrate and not from dipicolinic acid or other dipicolinate hydrate salts. The CaDP·3H2O infrared peaks and the effects of hydration are studied using quantum chemistry in the PQS software package. The quartet is associated with many modes including contributions from the Ca2+ counterion and hydration waters including Ca-O-H bends, H2O-Ca-O torsions, and O-C-O bends. The 1441 and 1015 cm-1 modes are planar pyridine modes with the 1441 cm-1 mode primarily a ring C-N stretch and the 1015 cm-1 mode primarily a ring C-C stretch.

AN - 67472688; 19590271 AB - With the increased threat of terrorist release of radioactive materials, there is a need for non-toxic decorporation agents to treat internal contamination with radionuclides. In this study, low molecular weight chitosan was evaluated for decorporation of radioactive cobalt (60Co). The affinity of chitosan for Co(II) was tested in vitro using spectrophotometric and potentiometric titration techniques. For in vivo studies, the effect of chitosan on ingested 60Co was evaluated using F344 rats administered a single dose followed by oral chitosan. Chitosan was also evaluated for systemic decorporation of 60Co following intravenous injection with repeated chitosan administration over 5 d. Control animals received 60Co without chelation treatment. Excreta and tissues were collected for analysis using gamma-counting techniques. Results from in vitro experiments confirmed the binding of Co(II) to chitosan, with the postulated formation of a mixed cobalt-chitosan-hydroxide complex species; a stability constant was calculated for this complex. For in vivo studies, oral administration of chitosan significantly reduced systemic absorption of orally administered 60Co as evidenced by an increase in fecal elimination and decrease in urinary elimination. However, oral administration of chitosan lactate slightly decreased fecal excretion of 60Co. Further, oral administration of chitosan significantly reduced 60Co levels in kidney, liver, and skeleton compared to control animals receiving 60Co alone. By the i.v. route, chitosan slightly reduced levels of 60Co in tissues compared to controls, although statistically significant reductions were only observed for blood and kidney. Overall, this commercially available chitosan oligosaccharide exhibited promising potential; further studies are warranted to evaluate the optimal dosing regimen and chemical modifications to increase effectiveness.

The Si-O bond lengths and Si-O-Si angles calculated with first-principles density functional theory methods as a function of pressure are also comparable with the bond lengths and angles observed for coesite and quartz within the experimental error. The similarity of the topological properties of the Si-O bonded interactions and the experimental and the geometry-optimized structures for the silica polymorphs provide a basis for understanding the properties and crystal chemistry of silica. The agreement supports the argument that the bulk of the structural and physical properties of the silica polymorphs are intrinsic properties of molecular-like coordination polyhedra such that the silica polymorphs can be pictured as "supermolecules" of silica bound by virtually the same forces that bind the Si and O atoms in simple siloxane molecules. The topology of the electron density distribution is consistent with the assertion that the Si-O bonded interaction arises from the net electrostatic attraction exerted on the nuclei by the electron density accumulated between the Si and O atoms. The correlation between the Si-O bond length and Si-O-Si angle is ascribed to the progressive local concentration of the electron density in the nonbonded lone pair region of the O atom rather than to a bonded interaction that involves the d-orbitals on Si. The accumulation of deformation electron density, Delta rho (r), in the bonded and nonbonded regions of the Si-O bond, the close proximity of the bond critical point, r (sub c) , of the bond with the nodal surface of the Laplacian and the negative value of the total energy density are taken as evidence that the bond has a nontrivial component of shared character. For M-O bonded interactions for first and second row metal atoms bonded to O, [nabla] (super 2) rho (r (sub c) ) is positive and increases linearly as rho (r (sub c) ) and G(r (sub c) )/rho (r (sub c) ) both increase and as the value of H(r (sub c) ) decreases; the greater the shared character of the interaction, the larger the values of both [nabla] (super 2) rho (r (sub c) ) and G(r (sub c) )/rho (r (sub c) ). In addition, a mapping of [nabla] (super 2) rho (r) serves to highlight those Lewis base domains that are susceptible to electrophilic attack by H, like the O atoms in coesite involved in bent Si-O-Si angles; the narrower the angle, the greater the affinity for H. On the basis of the net charges conferred on the Si and O atoms and the bonded radii of the two atoms, the Si-O bond for stishovite, with six-coordinated Si and three-coordinated O, is indicated to be more ionic in character than that in quartz with four-coordinated Si and two-coordinated O. Unlike the conclusion reached for ionic and crystal radii, it is the bonded radius of the O atom that increases with the increasing coordination number of Si, not the radius of the Si atom. The modeling of the electron density distributions for quartz, coesite, and beryl as a function of pressure suggests that the shared character of the bonded interactions in these minerals increases slightly with increasing pressure. The insight provided by the calculations and the modeling of the electron density distributions and the structures of the silica polymorphs bodes well for future Earth materials studies that are expected to improve and clarify our understanding of the connection between properties and structure within the framework of quantum mechanical observables, to find new and improved uses for the materials and to enhance our understanding of crystal chemistry and chemical reactions of materials in their natural environment at the atomic level.

Desiccation also has the potential to improve gas-phase-based treatments by reducing water saturation and therefore increasing sediment gas-phase permeability. Before this technology can be deployed in the field, concerns related to energy limitations, osmotic effects, and potential contaminant remobilization after rewetting must be addressed. A series of detailed, intermediate-scale laboratory experiments, using unsaturated homogeneous and heterogeneous systems, was conducted to improve our understanding of energy balance issues related to soil desiccation. The experiments were subsequently simulated with the multifluid flow simulator STOMP, using independently obtained hydraulic and thermal porous medium properties. In all experiments, the injection of dry air proved to be an effective means for removing essentially all moisture from the test media. Observed evaporative cooling generally decreased with increasing distance from the gas inlet chamber. The fine-grained sand embedded in the medium-grained sand of the heterogeneous system showed two local temperature minima associated with the cooling. The first one occurred because of evaporation in the adjacent medium-grained sand, whereas the second minimum was attributed to evaporative cooling in the fine-grained sand itself. Results of the laboratory tests were simulated accurately only if the thermal properties of the flow cell walls and insulation material were taken into account, indicating that the appropriate physics were incorporated into the simulator.

A total of 1,006 macrophage and 115 Salmonella proteins were identified with high confidence. Most of the Salmonella proteins were observed in the late stage of the infection time course, which is consistent with the fact that the bacterial cells proliferate inside RAW 264.7 macrophages. The peptide abundances of most of the identified macrophage proteins remained relatively constant over the time course of infection. Compared to those of the control, the peptide abundances of 244 macrophage proteins (i.e., 24% of the total identified macrophage proteins) changed significantly after infection. The functions of these Salmonella-affected macrophage proteins were diverse, including production of antibacterial nitric oxide (i.e., inducible nitric oxide synthase), production of prostaglandin H2 (i.e., cyclooxygenase 2), and regulation of intracellular traffic (e.g., sorting nexin 5 [SNX5], SNX6, and SNX9). Diverse functions of the Salmonella-affected macrophage proteins demonstrate a global macrophage response to Salmonella infection. Western blot analysis not only confirmed the proteomic results for a selected set of proteins but also revealed that (i) the protein abundance of mitochondrial superoxide dismutase increased following macrophage infection, indicating an infection-induced oxidative stress in mitochondria, and (ii) in contrast to infection of macrophages by wild-type Salmonella, infection by the sopB deletion mutant had no negative impact on the abundance of SNX6, suggesting a role for SopB in regulating the abundance of SNX6.

AN - 67486370; 19530657 AB - A bead-based sandwich immunoassay for botulinum neurotoxin serotype A (BoNT/A) has been developed and demonstrated using a recombinant 50 kDa fragment (BoNT/A-HC-fragment) of the BoNT/A heavy chain (BoNT/A-HC) as a structurally valid simulant. Three different anti-BoNT/A antibodies were attached to three different fluorescent dye encoded flow cytometry beads for multiplexing. The assay was conducted in two formats: a manual microcentrifuge tube format and an automated fluidic system format. Flow cytometry detection was used for both formats. The fluidic system used a novel microbead-trapping flow cell to capture antibody-coupled beads with subsequent sequential perfusion of sample, wash, dye-labeled reporter antibody, and final wash solutions. After the reaction period, the beads were collected for analysis by flow cytometry. Sandwich assays performed on the fluidic system gave median fluorescence intensity signals on the flow cytometer that were 2-4 times higher than assays performed manually in the same amount of time. Limits of detection were estimated at 1 pM (approximately 50 pg/mL for BoNT/A-HC-fragment) for the 15 min fluidic assay in buffer.

Although the complex geometries of fracture apertures, fracture networks, and pore spaces may make it difficult to accurately predict fluid flow in saturated (single-phase) subsurface systems, well-developed methods are available. The simulation of multiphase fluid flow in the subsurface is much more challenging because of the large density and/or viscosity ratios found in important applications (water/air in the vadose zone; water/oil, water/gas, gas/oil, and water/oil/gas in hydrocarbon reservoirs; water/air/nonaqueous phase liquids (nonaqueous phase liquids/dense nonaqueous phase liquids) in contaminated vadose zone systems; and gas/molten rock in volcanic systems, for example). In addition, the complex behavior of fluid-fluid-solid contact lines and their impact on dynamic contact angles must also be taken into account and coupled with the fluid flow. Here we review the methods that are currently being used to simulate pore-scale multiphase fluid flow and reactive transport in fractured and porous media. After the introduction, the review begins with an overview of the fundamental physics of multiphase fluids flow followed by a more detailed discussion of the complex dynamic behavior of contact lines and contact angles, an important barrier to accurate pore-scale modeling and simulation. The main part of the review focuses on five different approaches: pore network models, lattice gas and lattice Boltzmann methods, Monte Carlo methods, particle methods (molecular dynamics, dissipative particle dynamics, and smoothed particle hydrodynamics), and traditional grid-based computational fluid dynamics coupled with interface tracking and a contact angle model. Finally, the review closes with a discussion of future trends and challenges.

AN - 67472931; 19593341 AB - The Atmospheric Radiation Measurement program Raman lidar was upgraded in 2004 with a new data system that provides simultaneous measurements of both the photomultiplier analog output voltage and photon counts. We describe recent improvements to the algorithm used to merge these two signals into a single signal with improved dynamic range. The effect of modifications to the algorithm are evaluated by comparing profiles of water vapor mixing ratio from the lidar with radiosonde measurements over a six month period. The modifications that were implemented resulted in a reduction of the mean bias in the daytime water vapor mixing ratio from a 3% dry bias to well within 1%. This improvement was obtained by ignoring the temporal variation of the glue coefficients and using only the nighttime average glue coefficients throughout the entire diurnal cycle.

AN - 67574003; 19673287 AB - The accessibility of precipitated, intragrain U(VI) in a contaminated sediment to microbial reduction was investigated to ascertain geochemical and microscopic transport phenomena controlling U(VI) bioavailability. The sediment was collected from the U.S. Department of Energy Hanford site, and contained uranyl precipitates within the mm-sized granitic lithic fragments in the sediment. Bioreduction was investigated in a culture of a dissimilatory metal-reducing bacterium, Shewanellea oneidensis strain MR-1. Measurements of uranium concentration, speciation, and valence in aqueous and solid phases indicated that microbial reduction of intragrain U(VI) proceeded by two mechanisms: (1) sequentially coupled dissolution of intragrain uranyl precipitates, diffusion of dissolved U(VI) from intragrain regions, and microbial reduction of dissolved U(VI); and (2) U(VI) reduction in the intragrain regions by soluble, diffusible biogenic reductants. The bioreduction rate in the first pathway was over 3 orders of magnitude slowerthan that in comparable aqueous solutions containing aqueous U(VI) only. The slower bioreduction rate was attributed to (1) the release of calcium from the desorption/dissolution of calcium-containing minerals in the sediment, which subsequently altered U(VI) aqueous speciation and slowed U(VI) bioreducton and (2) alternative electron transfer pathways that reduced U(VI) in the intragrain regions and changed its dissolution and solubility behavior. The results implied that the overall rate of bioreduction of intragrain U(VI) will be influenced by the reactive mass transfer of U(VI) and biogenic reductants within intragrain regions, and geochemical reactions controlling major ion concentrations.

AN - 67463926; 19580511 AB - Here we identify the release of annexin A2 into the culture medium in response to low-dose X-radiation exposure and establish functional linkages to an established paracrine factor-mediated anchorage-independent growth response. Using a standard bicameral coculture model, we demonstrate that annexin A2 is secreted into the medium by irradiated cells (seeded in upper chamber) and is capable of binding to nonirradiated neighboring cells (seeded in lower chamber). The paracrine factor-mediated anchorage-independent growth response to low-dose X irradiation is reduced when irradiated annexin A2-silenced (shRNA) JB6 cells are co-cultured with nonirradiated cells relative to co-culture with irradiated annexin A2-competent vector control cells. Consistent with this observation, purified bovine annexin A2 tetramer induces anchorage-independent growth. These observations suggest that annexin A2 regulates, in part, the radiation paracrine factor-specific anchorage-independent growth response in JB6 cells.

This study was undertaken to investigate mineral transformations associated with microbial reduction of Fe (super 3+) and oxidation of Fe (super 2+) in solid minerals. A fluid sample from the 2450 m depth of the Chinese Continental Scientific Drilling project was collected, and Fe (super 3+) -reducing and Fe (super 2+) -oxidizing microorganisms were enriched. The enrichment cultures displayed reduction of Fe (super 3+) in nontronite and ferric citrate, and oxidation of Fe (super 2+) in vivianite, siderite, and monosulfide (FeS). Additional experiments verified that the iron reduction and oxidation was biological. Oxidation of FeS resulted in the formation of goethite, lepidocrocite, and ferrihydrite as products. Although our molecular microbiological analyses detected Thermoanaerobacter ethanolicus as a predominant organism in the enrichment culture, Fe (super 3+) reduction and Fe (super 2+) oxidation may be accomplished by a consortia of organisms. Our results have important environmental and ecological implications for iron redox cycling in solid minerals in natural environments, where iron mineral transformations may be related to the mobility and solubility of inorganic and organic contaminants.

The impregnation of Pd into the porous SYT/LDC anode was found to significantly enhance the anode performance. With the addition of 1.5 wt.% Pd into the anode, the anodic overpotential was reduced to about half of the original value. The single cell with the Pd-impregnated SYT/LDC anode showed a maximum power density of 1006 and 577 mW cm super(-2) at 850 and 800 C in dry H sub(2), respectively, which was more than twice of that prior to impregnation. The Pd-impregnated composite anode exhibited good tolerance to sulfur, with essentially no decay in performance in H sub(2) containing up to 50 ppm H sub(2)S.

In the meantime, additional mechanical stresses will also be created by mechanical flattening during the stack assembly process. In order to ensure the structural integrity of the cell and stack of SOFC, it is necessary to develop failure criteria for SOFC PEN structures based on the initial flaws occurred during cell sintering and stack assembly. In this paper, the global relationship between the critical energy release rate and critical curvature and maximum displacement of the warped cells caused by the temperature changes as well as mechanical flattening process is established so that possible failure of SOFC PEN structures may be predicted deterministically by the measurement of the curvature and displacement of the warped cells.

The model takes into account the generation of gas atoms and vacancies, and the elastic interaction between diffusive species and defects as well as the inhomogeneity of elasticity and diffusivity. The simulations show that gas bubble nucleation is much easier at grain boundaries than inside grains due to the trapping of gas atoms and the high mobility of vacancies and gas atoms in grain boundaries. Helium bubble formation at unstable vacancy clusters generated by irradiation depends on the mobilities of the vacancies and He, and the continuing supply of vacancies and He. The formation volume of the vacancy and He has a strong effect on the gas bubble nucleation at dislocations. The effective thermal conductivity strongly depends on the bubble volume fraction, but weakly on the morphology of the bubbles.

AN - 67328371; 19442406 AB - This manuscript addresses the consequences of the common practice of assuming that the gravel fraction of sediments does not participate in sorption reactions and thus sorption quantified by the distribution coefficient (K(d)) construct can be estimated from laboratory tests on sediments less than 2 mm size fraction. However, this common assumption can lead to inaccurate estimates of the mobility and sorption affinity of many radionuclides (e.g., Tc, U, and Np) on gravel dominated sediments at the Hanford Site and other locations. Laboratory batch sorption experiments showed that the distribution coefficients measured using only sediment less than 2 mm size fraction and correcting for inert gravel fraction were not in agreement with those obtained from the bulk sediments including gravel (larger than 2 mm size fraction), depending on the radionuclide. The least reactive radionuclide, Tc had K(d) values for bulk sediment with negligible deviations from the inert gravel corrected K(d) values measured on less than 2 mm size fraction. However, differences between measured K(d) values using sediment less than 2 mm size fraction and the K(d) values on the bulk sediment were significant for intermediately and strongly reactive radionuclides such as U and Np, especially on the sediment with gravel fractions that contained highly reactive sites. Highly reactive sites in the gravel fraction were attributed to the presence of Fe oxide coatings and/or reactive fracture faces on the gravel surfaces. Gravel correction factors that use the sum of the K(d)(,<2 mm) and K(d)(,>2 mm) values to estimate the K(d) for the bulk sediment were found to best describe K(d) values for radionuclides on the bulk sediment. Gravel correction factors should not be neglected to predict precisely the sorption capacity of the bulk sediments that contain more than 30% gravel. In addition, more detailed characterization of gravel surfaces should be conducted to identify whether higher reactive sorbents are present in the gravels.

AN - 67489690; 19603635 AB - Macroscopic and spectroscopic investigations (XAFS, XRF, and TRLIF) on Hanford contaminated vadose zone sediments from the U-tank farm showed that U(VI) exists as different surface phases as a function of depth below ground surface (bgs). Secondary precipitates of U(VI) silicate precipitates (boltwoodite and uranophane) were present dominantly in shallow-depth sediments (15-16 m bgs), while adsorbed U(VI) phases and polynuclear U(VI) surface precipitates were considered to dominate in intermediate-depth sediments (20-25 m bgs). Only natural uranium was observed in the deeper sediments (> 28 m bgs) with no signs of contact with tank wastes containing Hanford-derived U(VI). Across all depths, most of the U(VI) was preferentially associated with the silt and clay size fractions of sediments. Strong correlation between U(VI) and Ca was found in the shallow-depth sediments, especially for the precipitated U(VI) silicates. Because U(VI) silicate precipitates dominate in the shallow-depth sediments, the released U(VI) concentration by macroscopic (bi)carbonate leaching resulted from both desorption and dissolution processes. Having different U(VI) surface phases in the Hanford contaminated sediments indicates that the U(VI) release mechanism could be complicated and that detailed characterization of the sediments using several different methods would be needed to estimate U(VI) fate and transport correctly in the vadose zone.

This work examines potential climate change impacts on the productivity of five major crops in eastern China: canola, corn, potato, rice, and winter wheat. In addition to determining domain-wide trends, the objective is to identify vulnerable and emergent regions under future climate conditions, defined as having a greater than 10% decrease and increase in productivity, respectively. Data from the ICTP RegCM3 regional climate model for baseline (1961-1990) and future (2071-2100) periods under A2 scenario conditions are used as input for the EPIC agro-ecosystem simulation model in the domain [30 super(o)N, 108 super(o)E] to [42 super(o)N, 123 super(o)E]. Simulations are performed with and without the enhanced CO sub(2)-fertilization effect. Results indicate that aggregate potential productivity (i.e. if the crop is grown everywhere) increases 6.5% for rice, 8.3% for canola, 18.6% for corn, 22.9% for potato, and 24.9% for winter wheat, although with significant spatial variability for each crop. However, without the enhanced CO sub(2)-fertilization effect, potential productivity declines in all cases ranging from 2.5 to 12%. Interannual yield variability remains constant or declines in all cases except rice. Climate variables are found to be more significant drivers of simulated yield changes than changes in soil properties, except in the case of potato production in the northwest where the effects of wind erosion are more significant. Overall, in the future period corn and winter wheat benefit significantly in the North China Plain, rice remains dominant in the southeast and emerges in the northeast, potato and corn yields become viable in the northwest, and potato yields suffer in the southwest with no other crop emerging as a clear beneficiary from among those simulated in this study.

Understanding the geochemical processes that mediate mercury transformations in the subsurface is necessary to predict its fate and transport. In this study, we investigated the redox transformation of mercuric Hg (Hg[II]) in the presence of the Fe(II)/Fe(III) mixed valence iron oxide mineral magnetite. Kinetic and spectroscopic experiments were performed to elucidate reaction rates and mechanisms. The experimental data demonstrated that reaction of Hg(II) with magnetite resulted in the loss of Hg(II) and the formation of volatile elemental Hg (Hg[0]). Kinetic experiments showed that Hg(II) reduction occurred within minutes, with reaction rates increasing with increasing magnetite surface area (0.5 to 2 m2/L) and solution pH (4.8 to 6.7), and decreasing with increasing chloride concentration (10-6 to 10-2 mol/L). Mssbauer spectroscopic analysis of reacted magnetite samples revealed a decrease in Fe(II) content, corresponding to the oxidation of Fe(II) to Fe(III) in the magnetite structure. X-ray photoelectron spectroscopy detected the presence of Hg(II) on magnetite surfaces, implying that adsorption is involved in the electron transfer process.

The long half-life, high environmental mobility (as Tc(VII)O (sub 4) (super -) ) and its possible uptake into the food chain cause (super 99) Tc to be a significant environmental contaminant. In this study, we evaluated the role of Fe(II) in biologically reduced clay mineral, nontronite (NAu-2), in reducing Tc(VII)O (sub 4) (super -) to poorly soluble Tc(IV) species as a function of pH and Fe(II) concentration. The rate of Tc(VII) reduction by Fe(II) in NAu-2 was higher at neutral pH (pH 7.0) than at acidic and basic pHs when Fe(II) concentration was low (<1 mmol/g). The effect of pH, however, was insignificant at higher Fe(II) concentrations. The reduction of Tc(VII) by Fe(II) associated with NAu-2 was also studied in the presence of common subsurface oxidants including iron and manganese oxides, nitrate, and oxygen, to evaluate the effect of these oxidants on the enhancement and inhibition of Tc(VII) reduction, and reoxidation of Tc(IV). Addition of iron oxides (goethite and hematite) to the Tc(VII)-NAu-2 system, where Tc(VII) reduction was ongoing, enhanced reduction of Tc(VII), apparently as a result of re-distribution of reactive Fe(II) from NAu-2 to more reactive goethite/hematite surfaces. Addition of manganese oxides stopped further Tc(VII) reduction, and in case of K (super +) -birnessite, it reoxidized previously reduced Tc(IV). Nitrate neither enhanced reduction of Tc(VII) nor promoted reoxidation of Tc(IV). Approximately 11% of Tc(IV) was oxidized by oxygen. The rate and extent of Tc(IV) reoxidation was found to strongly depend on the nature of the oxidants and concentration of Fe(II). When the same oxidants were added to aged Tc reduction products (mainly NAu-2 and TcO (sub 2) .nH (sub 2) O), the extent of Tc(IV) reoxidation decreased significantly relative to fresh Tc(IV) products. Increasing NAu-2 concentration also resulted in the decreased extent of Tc(IV) reoxidation. The results were attributed to the effect of NAu-2 aggregation that effectively retained Tc(IV) in the solid and decreased its vulnerability to reoxidation. Overall, our results implied that bioreduced clay minerals could play an important role in reducing Tc(VII) and in maintaining the long-term stability of reduced Tc(IV).

High-temperature leak tests with helium showed very stable leakage of 0.01-0.02 sccm cm super(-1) for 28,366 h under a low applied compressive stress of 82 kPa (12 psi). Post-mortem SEM and EDS analyses of the mica showed minimum degradation in terms of changes in microstructure and chemical composition, although there appeared to be some Ag migration and segregation at interstices between mica flakes. Fluorine was also found to be released from mica. Overall, the low, constant leakage through the hybrid mica/Ag seals clearly demonstrated a very promising candidate for SOFC sealing.

Electrode resistances decreased in proportion to P(O sub(2)) super(1/2) for the LSM electrode in both cathodic and anodic directions to at least 10 MPa ([not, vert, similar]100 atm), a decrease that was attributed to dissociative oxygen adsorption and related phenomena. For the LSM-20/zirconia composite electrode, resistances decreased in proportion to P(O sub(2)) super(1/4) across the entire pressure range considered. Two principal features appeared in the impedance spectra, one that showed a P(O sub(2)) super(1/4) dependence attributed to charge transfer reactions, and a smaller feature that was nearly pressure-independent, possibly due to transport in the zirconia portion of the composite. For the LSM-20/ceria composite electrode, resistances decreased as P(O sub(2)) super(0.3-0.4) at high pressure, depending on temperature. Two features appeared in the impedance spectra: one at low to intermediate frequency having a [not, vert, similar]P(O sub(2)) super(1/2) dependence and a second at high frequency having a [not, vert, similar]P(O sub(2)) super(1/4) dependence. These features are attributed to dissociative oxygen adsorption and to charge transfer reactions, respectively. Results suggest that cathodic losses can be substantially lowered by operation of solid oxide fuel cells at greater than ambient pressure.

(Diatom) AN - 20619160; 9317765 AB - Microalgae are expected to play a significant role in greenhouse gas mitigation because they can utilize CO2 from power plant flue gases directly while producing a variety of renewable carbon-neutral biofuels. In order for such a microalgal climate change mitigation strategy to become economically feasible, it will be necessary to significantly improve biomass productivities. One approach to achieve this objective is to reduce, via mutagenesis, the number of light-harvesting pigments, which, according to theory, should significantly improve the light utilization efficiency, primarily by increasing the light intensity at which photosynthesis saturates (I s). Employing chemical (ethylmethylsulfonate) and UV mutagenesis of a wild-type strain of the diatom Cyclotella, approximately 10,000 pigment mutants were generated, and two of the most promising ones (CM1 and CM1-1) were subjected to further testing in both laboratory cultures and outdoor ponds. Measurements of photosynthetic oxygen production rates as a function of light intensity (i.e., P--I curves) of samples taken from laboratory batch cultures during the exponential and linear growth phase indicated that the light intensity at which photosynthesis saturates (I s) was two to three times greater in the pigment mutant CM1-1 than in the wild type, i.e., 355--443 versus 116--169 mmol/m s, respectively. While theory, i.e., the Bush equation, predicts that such a significant gain in I s should increase light utilization efficiencies and thus biomass productivities, particularly at high light intensities, no improvements in biomass productivities were observed in either semi-continuous laboratory cultures or outdoor ponds. In fact, the maximum biomass productivity in semi-continuous laboratory culture was always greater in the wild type than in the mutant, namely 883 versus 725 mg/L day, respectively, at low light intensity (200 mmol/m s) and 1,229 versus 1,043 mg/L day, respectively, at high light intensity (1,000 mmol/m s). Similarly, the biomass productivities measured in outdoor ponds were significantly lower for the mutant than for the wild type. Given that these mutants have not been completely characterized in these initial studies, the exact reasons for their poor performance are not known. Most likely, it is possible that the mutation procedure affected other photosynthetic or metabolic processes. This hypothesis was partially validated by the observation that the pigment mutant had a longer lag period following inoculation, a lower maximum specific growth rate, and poorer stability than the wild type.

9350434 AB - Limiting atmospheric carbon dioxide (CO sub(2)) concentrations to low levels requires strategies to manage anthropogenic carbon emissions from terrestrial systems as well as fossil fuel and industrial sources. We explore the implications of fully integrating terrestrial systems and the energy system into a comprehensive mitigation regime that limits atmospheric CO sub(2) concentrations. We find that this comprehensive approach lowers the cost of meeting environmental goals but also carries with it profound implications for agriculture: Unmanaged ecosystems and forests expand, and food crop and livestock prices rise. Finally, we find that future improvement in food crop productivity directly affects land-use change emissions, making the technology for growing crops potentially important for limiting atmospheric CO sub(2) concentrations.

13267456 AB - The influence of ammonium availability on bacterial community structure and the physiological status of Geobacter species during in situ bioremediation of uranium-contaminated groundwater was evaluated. Ammonium concentrations varied by 2 orders of magnitude (<4 to 400 *mM) across the study site. Analysis of 16S rRNA sequences suggested that ammonium may have been one factor influencing the community composition prior to acetate amendment with Rhodoferax species predominating over Geobacter species with higher ammonium and Dechloromonas species dominating at the site with lowest ammonium. However, once acetate was added and dissimilatory metal reduction was stimulated, Geobacter species became the predominant organisms at all locations. Rates of U(VI) reduction appeared to be more related to acetate concentrations rather than ammonium levels. In situ mRNA transcript abundance of the nitrogen fixation gene, nifD, and the ammonium transporter gene, amtB, in Geobacter species indicated that ammonium was the primary source of nitrogen during uranium reduction. The abundance of amtB was inversely correlated to ammonium levels, whereas nifD transcript levels were similar across all sites examined. These results suggest that nifD and amtB expression are closely regulated in response to ammonium availability to ensure an adequate supply of nitrogen while conserving cell resources. Thus, quantifying nifD and amtB transcript expression appears to be a useful approach for monitoring the nitrogen-related physiological status of subsurface Geobacter species. This study also emphasizes the need for more detailed analysis of geochemical and physiological interactions at the field scale in order to adequately model subsurface microbial processes during bioremediation.

AN - 733327466; 19381395 AB - A renewable surface biosensor for rapid detection of botulinum neurotoxin serotype A is described based on fluidic automation of a fluorescence sandwich immunoassay, using a recombinant protein fragment of the toxin heavy chain ( approximately 50 kDa) as a structurally valid simulant. Monoclonal antibodies AR4 and RAZ1 bind to separate non-overlapping epitopes of the full botulinum holotoxin ( approximately 150 kDa). Both of the targeted epitopes are located on the recombinant fragment. The AR4 antibody was covalently bound to Sepharose beads and used as the capture antibody. A rotating rod flow cell was used to capture these beads delivered as a suspension by a sequential injection flow system, creating a 3.6 microL column. After perfusing the bead column with sample and washing away the matrix, the column was perfused with Alexa 647 dye-labeled RAZ1 antibody as the reporter. Optical fibers coupled to the rotating rod flow cell at a 90 degrees angle to one another delivered excitation light from a HeNe laser (633 nm) using one fiber and collected fluorescent emission light for detection with the other. After each measurement, the used Sepharose beads are released and replaced with fresh beads. In a rapid screening approach to sample analysis, the toxin simulant was detected to concentrations of 10 pM in less than 20 minutes using this system.

AN - 67130440; 19321520 AB - Antibodies are widely used for diagnostic and therapeutic applications because of their sensitive and specific recognition of a wide range of targets; however, their application is limited by their structural complexity. More demanding applications require greater stability than can be achieved by immunoglobulin-based reagents. Highly stable, protein-based affinity reagents are being investigated for this role with the goal of identifying a suitable scaffold that can attain specificity and sensitivity similar to that of antibodies while performing under conditions where antibodies fail. We have engineered Top7--a highly stable, computationally designed protein--to specifically bind human CD4 by inserting a peptide sequence derived from a CD4-specific antibody. Molecular dynamics simulations were used to evaluate the structural effect of the peptide insertion at a specific site within Top7 and suggest that this Top7 variant retains conformational stability over 100 degrees C. This engineered protein specifically binds CD4 and, consistent with simulations, is extremely resistant to thermal and chemical denaturation--retaining its secondary structure up to at least 95 degrees C and requiring 6 M guanidine to completely unfold. This CD4-specific protein demonstrates the functionality of Top7 as a viable scaffold for use as a general affinity reagent which could serve as a robust and inexpensive alternative to antibodies.

AN - 67120740; 19359845 AB - Ambient air monitoring for non-research applications (i.e., compliance) occurs throughout the world. Often, air sampling systems employed for these purposes employ simple yet robust equipment capable of handling the rigors of demanding sampling schedules and harsh environments. At the Hanford Site (near Richland, Washington) concentrations of radionuclides in ambient air are monitored continuously at 44 locations. In 2004, mechanical dry-gas meters were incorporated into the Hanford Site ambient air sample collection system to allow the direct measurement of sample volumes. These meters replaced an airflow measurement system that required two manual flow measurements and a sample duration measurement to determine sample volume. A six-month evaluation of the dry-gas meters compared sample volumes calculated using the original flow-rate method to the sample volume measured directly by the dry-gas meter. The two methods provided sample volumes that were within 15% of each other 87% of the time. The results indicated that for instances where the sample volume measured by the two methods differed by more than 15%, the dry-gas meter method provided a more accurate sample volume measurement. The results of the evaluation further indicated that the dry-gas meters provided more accurate sample volumes for all samples, resulting in greater confidence in the calculated concentration results.

In this study, the impact of major additive components on surface and interfacial tensions for organic mixtures and wastewater was investigated. Organic mixture and wastewater compositions were based on CCl (sub 4) mixtures released at the U.S. Department of Energy's Hanford site, where CCl (sub 4) was discharged simultaneously with dibutyl butyl phosphonate, tributyl phosphate, dibutyl phosphate, and a machining lard oil. A considerable amount of wastewater consisting primarily of nitrates and metal salts was also discharged. The measured tension values revealed that the addition of these additive components caused a significant lowering of the interfacial tension with water or wastewater and the surface tension of the wastewater phase in equilibrium with the organic mixtures, compared with pure CCl (sub 4) , but had minimal effect on the surface tension of the NAPL itself. These results led to large differences in spreading coefficients for several mixtures, where the additives caused both a higher (more spreading) initial spreading coefficient and a lower (less spreading) equilibrium spreading coefficient. This indicates that if these mixtures migrate into uncontaminated areas, they will tend to spread quickly but will form a higher residual NAPL saturation after equilibrium than pure CCl (sub 4) . With time, CCl (sub 4) probably volatilizes more rapidly than other components in the originally disposed mixtures and the lard oil and phosphates would become more concentrated in the remaining NAPL, resulting in a lower interfacial tension for the mixture. These results show that the behavior of organic chemical mixtures should be accounted for in flow and transport models.

Chemical extractions, X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR) were used to identify and characterize Fe(III) phases. The mineralogical analysis revealed schwertmannite and goethite as the principal Fe(III) phases in the sediments. Schwertmannite particles occurred as sub-micron sized spheroids. Their transformation into goethite occurred at the GB site where poorly-crystallized goethite rich in surface-bound sulfate was initially formed. In contrast, no schwertmannite transformation occurred at the FR site. The resulting goethite in GB sediments was also of spherical morphology and resulted from an in situ phase transformation involving the conversion of bulk-bound schwertmannite sulfate ions into goethite surface complexes. Chemical extractions moreover showed that the poorly-crystallized goethite particles were subject to further crystallization accompanied by sulfate desorption. Changes in sulfate speciation preceded its desorption, with a conversion of bidentate- to monodentate-bound sulfate surface complexes. Laboratory sediment incubation experiments were conducted to evaluate the effect of mineral transformation on water chemistry. Incubation experiments were carried out with schwertmannite-containing sediments and aerobic AMD waters with different pH and chemical composition. The pH decreased to 1.9-2.2 in all suspensions and the concentrations of dissolved Fe and S increased significantly. Regardless of differences in the initial water composition, pH, Fe and S were similar in suspensions of the same sediment. XRD measurements revealed that schwertmannite transformed into goethite in GB and FR sediments during laboratory incubation. The incubation experiments demonstrated that schwertmannite transformation controlled AMD water chemistry under no-flow, batch conditions.

Current technology is limited primarily to lysimeters, which directly measure water flux but are expensive and may in some way disrupt flow, causing errors in the measured drainage. We report on design considerations and field tests of an alternative approach, passive wick fluxmeters, which use a control tube to minimize convergent or divergent flow. Design calculations with a quasi-three-dimensional model illustrate how convergence and divergence can be minimized for a range of soil and climatic conditions under steady state and transient fluxes using control tubes of varying heights. There exists a critical recharge rate for a given wick length, where the fluxmeter collection efficiency is 100% regardless of the height of the control tube. Otherwise, convergent or divergent flow will occur, especially when the control tube height is small. While divergence is eliminated in coarse soils using control tubes, it is reduced but not eliminated in finer soils, particularly for fluxes 60% annual precipitation) from gravel surfaces and least (no drainage) from silt loam soils. In Oregon and New Mexico, United States, and in New Zealand, drainage showed substantial spatial variability. The New Mexico tests were located in semiarid canyon bottom terraces, with flash flood prone locations having extremely high drainage/precipitation ratios. In the wettest environments, drainage was found to be closely linked to the rate and duration of precipitation events.

Sequestering CO[sub]2 in deep geological formations has been proposed as a long-term solution to help stabilize CO[sub]2 levels. However, before such technology can be developed and implemented, a basic understanding of H[sub]2O-CO[sub]2 systems and the chemical interactions of these fluids with the host formation must be obtained. Important issues concerning mineral stability, reaction rates, and carbonate formation are all controlled or at least significantly impacted by the kinetics of rock-water reactions in mildly acidic, CO[sub]2-saturated solutions. Basalt has recently been identified as a potentially important host formation for geological sequestration. Dissolution kinetics of the Columbia River Basalt (CRB) were measured for a range of temperatures (25-90 [degree]C) under mildly acidic to neutral pH conditions using the single-pass flow- through test method. Under anaerobic conditions, the normalized dissolution rates for CRB decrease with increasing pH (3 [less-than-or-equals, slant] pH [less-than-or-equals, slant] 7) with a slope, [eta], of - 0.15 +/- 0.01. Activation energy, E[sub]a, has been estimated at 32.0 +/- 2.4 kJ mol[super]-1. Dissolution kinetics measurements like these are essential for modeling the rate at which CO[sub]2-saturated fluids react with basalt and ultimately drive conversion rates to carbonate minerals in situ..

Monoclonal antibodies AR4 and RAZ1 bind to separate non-overlapping epitopes of the full botulinum holotoxin (6150 kDa). Both of the targeted epitopes are located on the recombinant fragment. The AR4 antibody was covalently bound to Sepharose beads and used as the capture antibody. A rotating rod flow cell was used to capture these beads delivered as a suspension by a sequential injection flow system, creating a 3.6 kL column. After perfusing the bead column with sample and washing away the matrix, the column was perfused with Alexa 647 dye-labeled RAZ1 antibody as the reporter. Optical fibers coupled to the rotating rod flow cell at a 90 angle to one another delivered excitation light from a HeNe laser (633 nm) using one fiber and collected fluorescent emission light for detection with the other. After each measurement, the used Sepharose beads are released and replaced with fresh beads. In a rapid screening approach to sample analysis, the toxin simulant was detected to concentrations of 10 pM in less than 20 minutes using this system.

At temperatures below 273 K, a fraction of atmospheric particles act as sites for ice-crystal formation. Atmospheric ice crystals-which are incorporated into clouds that cover more than a third of the globe super(1)-are thought to initiate most of the terrestrial precipitation super(2). Before the switch to unleaded fuel last century, the atmosphere contained substantial quantities of particulate lead; whether this influenced ice-crystal formation is not clear. Here, we combine field observations of ice-crystal residues with laboratory measurements of artificial clouds, to show that anthropogenic lead-containing particles are among the most efficient ice-forming substances commonly found in the atmosphere super(3). Using a global climate model, we estimate that up to 0.8 W m super(-2) more long-wave radiation is emitted when 100% of ice-forming particles contain lead, compared with when no particles contain lead. We suggest that post-industrial emissions of particulate lead may have offset a proportion of the warming attributed to greenhouse gases.

The Karhunen-Loeve decomposition is used to represent log hydraulic conductivity Y=lnK (sub s) . The hydraulic head h and average pore-velocity v are obtained by solving the continuity equation coupled with Darcy's law with random hydraulic conductivity field. The concentration is computed by solving a stochastic advection-dispersion equation with stochastic average pore-velocity v computed from Darcy's law. The PCM approach is an extension of the generalized polynomial chaos (gPC) that couples gPC with probabilistic collocation. By using sparse grid points in sample space rather than standard grids based on full tensor products, the PCM approach becomes much more efficient when applied to random processes with a large number of random dimensions. Monte Carlo (MC) simulations have also been conducted to verify accuracy of the PCM approach and to demonstrate that the PCM approach is computationally more efficient than MC simulations. The numerical examples demonstrate that the PCM approach on sparse grids can efficiently simulate solute transport in randomly heterogeneous porous media with large variances.

Because this class of steels is the leading structural material for test blankets in ITER and future fusion power systems, the range of ongoing research activities is extremely broad. Since, it is not possible to discuss all relevant work in this brief review, the objective of this paper is to highlight significant issues that have received recent attention. These include: (1) efforts to measure and understand radiation-induced hardening and embrittlement at temperatures [less-than-or-equals, slant]400 C, (2) experiments and modeling to characterize the effects of He on microstructural evolution and mechanical properties, (3) exploration of approaches for increasing the high-temperature (>550 C) creep resistance by introduction of a high-density of nanometer scale dispersoids or precipitates in the microstructure, (4) progress toward structural design criteria to account for loading conditions involving both creep and fatigue, and (5) development of nondestructive examination methods for flaw detection and evaluation.

Pure metal dosimetry materials from the second irradiation (STIP-II) have been analyzed for their total helium and hydrogen contents and their release characteristics with temperature (TDS). Total helium results are similar to those observed earlier from the first irradiation experiment (STIP-I), with concentrations ranging from [not, vert, similar]500 to [not, vert, similar]1000 appm. Hydrogen contents varied over a larger range from [not, vert, similar]100 to [not, vert, similar]60 000. super(3)He/ super(4)He ratios were generally consistent with expectations, except for Ti, Nb, and Ta which showed lower values due to super(3)He from decay of irradiation-generated tritium. Some differences were observed in the hydrogen TDS data for the control and irradiated materials, including some evidence for additional lower-temperature release and for multiple release peaks. Additionally, differences were noted in the releases for irradiated material that been cleaned versus material that had no cleaning.

Vacancies trapped at the GBs diffuse along the GBs with migration energies much less than that within the perfect crystal. Long-time dynamics simulations of diffusion pathways reveal that vacancies migrate one-dimensionally along specific directions in both GBs: directly along close-packed rows in the [sigma]3 GB, and in zigzag paths within the [sigma]11 GB. Also, dimer saddle point searches show that He interstitials can diffuse along the GBs with migration energies of 0.4-0.5 eV, similar to those of individual vacancies at the GBs, and the corresponding mechanisms are determined. The rate-controlling activation energy for migration of a He-divacancy cluster in the GBs determined using the dimer method is about 0.9 eV. This is comparable to the migration energy for a He-divacancy cluster in bulk a-Fe.

However, SiC is susceptible to many forms of corrosion in water and in water vapor where silica formation is required as a protective layer because silica forms stable hydroxides that are volatile, even at low temperatures. SiC-composites have an additional concern that fine-grained fibers and weak interfaces provide the required fracture toughness, but these components may also exhibit susceptibility to corrosion that can compromise material properties. In this work we examine and review the compatibility of fibers and interfaces, as well as the SiC matrix, in proposed fusion environments including first wall, tritium breeding, and blanket modules and module coolants.

Tc is highly mobile in its most oxidized state [View the MathML source] and less mobile in the reduced form [Tc(IV)O[sub]2[sup].nH[sub]2O]. Here we investigate the potential for oxidation of Tc(IV) that was heterogeneously reduced by reaction with biogenic Fe(II) in two sediments differing in mineralogy and aggregation state; unconsolidated Pliocene-age fluvial sediment from the upper Ringold (RG) Formation at the Hanford Site and a clay-rich saprolite from the Field Research Center (FRC) background site on the Oak Ridge Site. Both sediments contained Fe(III) and Mn(III/IV) as redox active phases, but FRC also contained mass-dominant Fe-phyllosilicates of different types. Shewanella putrefaciens CN32 reduced Mn(III/IV) oxides and generated Fe(II) that was reactive with Tc(VII) in heat-killed, bioreduced sediment. After bioreduction and heat-killing, biogenic Fe(II) in the FRC exceeded that in RG by a factor of two. More rapid reduction rates were observed in the RG that had lower biogenic Fe(II), and less particle aggregation. EXAFS measurements indicated that the primary reduction product was a TcO[sub]2-like phase in both sediments. The biogenic redox product Tc(IV) oxidized rapidly and completely in RG when contacted with air. Oxidation, in contrast, was slow and incomplete in the FRC, in spite of similar molecular scale speciation of Tc compared to RG. X-ray microprobe, electron microprobe, X-ray absorption spectroscopy, and micro X-ray diffraction were applied to the whole sediment and isolated Tc-containing particles. These analyses revealed that non-oxidizable Tc(IV) in the FRC existed as complexes with octahedral Fe(III) within intra-grain domains of 50-100 [micro]m-sized, Fe-containing micas presumptively identified as celadonite. The markedly slower oxidation rates in FRC as compared to RG were attributed to mass-transfer-limited migration of O[sub]2 into intra-aggregate and intraparticle domains where Tc(IV) existed; and the formation of unique, oxidation-resistant, intragrain Tc(IV)-Fe(III) molecular species.

Positive surface charge can increase particle internalization, and in some cases can also increase particle toxicity, but the underlying mechanisms are largely unknown. Here we identify the cellular interaction and pathway of positively charged submicrometer synthetic amorphous silica particles, which are used extensively in a wide range of industrial applications, and are explored for drug delivery and medical imaging and sensing. Using time lapse fluorescence imaging in living cells and other quantitative imaging approaches, it is found that heparan sulfate proteoglycans play a critical role in the attachment and internalization of the particles in alveolar type II epithelial cell line (C10), a potential target cell type bearing apical microvilli. Specifically, the transmembrane heparan sulfate proteoglycan, syndecan-1, is found to mediate the initial interactions of the particles at the cell surface, their coupling with actin filaments across the cell membrane, and their subsequent internalization via macropinocytosis. The observed interaction of syndecan molecules with the particle prior to their engagement with actin filaments suggests that the particles initiate their own internalization by facilitating the clustering of the molecules, which is required for the actin coupling and subsequent internalization of syndecan. Our observations identify a new role for syndecan-1 in mediating the cellular interactions and fate of positively charged submicrometer amorphous silica particles in the alveolar type II epithelial cell, a target cell for inhaled particles.

AN - 67255419; 19452870 AB - A saline-alkaline brine containing high concentration of U(VI) was accidentally spilled at the Hanford Site in 1951, introducing 10 tons of U into sediments under storage tank BX-102. U concentrations in the deep vadose zone and groundwater plumes increase with time, yet how the U has been migrating is not fully understood. We simulated the spill event in laboratory soil columns, followed by aging, and obtained spatially resolved U partitioning and speciation along simulated plumes. We found after aging, at apparent steady state, that the pore aqueous phase U concentrations remained surprisingly high (up to 0.022 M), in close agreement with the recently reported high U concentrations (up to 0.027 M) in the vadose zone plume (1). The pH values of aged pore liquids varying from 10 to 7, consistent with the measured pH of the field borehole sediments varying from 9.5 to 7.4 (2), from near the plume source to the plume front. The direct measurements of aged pore liquids together with thermodynamic calculations using a Pitzer approach revealed that UO2(CO3)3(4-) is the dominant aqueous U species within the plume body (pH 8-10), whereas Ca2UO2(CO3)3 and CaUO2(CO3)32- are also significant in the plume frontvicinity (pH 7-8), consistent with that measured from field borehole pore-waters (3). U solid phase speciation varies at different locations along the plume flow path and even within single sediment grains, because of location dependent pore and micropore solution chemistry. Our results suggest that continuous gravity-driven migration of the highly stable U02(CO3)34 in the residual carbonate and sodium rich tank waste solution is likely responsible for the detected growing U concentrations in the vadose zone and groundwater.

AN - 67127101; 19242951 AB - The ability to process and purify engineered nanomaterials using near critical or supercritical fluids (NcFs or ScFs) has enormous potential for the application at various stages of the development of green nanomaterials. The dispersibility of octanethiol-stabilized gold nanocrystals of different core sizes is explored, which were chosen to serve as model nanomaterials of general interest in compressed ethane and propane over a wide range of fluid conditions. Both solvents have enormous potential for the environmentally benign processing and transport of engineered nanomaterials due to their nominal toxicity and high degree of tunability and processability that can essentially eliminate solvent waste. The dispersibility is determined by measuring the absorption spectra of dispersions of various sizes of nanocrystals in NcFs. To better understand the obtained results three models, the total interaction theory, the sedimentation coefficient equation, and the Chrastil method, are discussed. Nanoparticle dispersibility versus density plots are strongly dependent on nanoparticle size and solvent conditions, with the dispersion of larger nanocrystals more dependent on changes of pressure or density at a given temperature. For the range of nanoparticle sizes studied, compressed ethane at 25 degrees C leads to a greater tunability of nanoparticle dispersion when compared with compressed propane at 65 degrees C. For equivalent pressures, compressed propane is found to provide better solubility than ethane due to its higher density. The results quantitatively demonstrate that NcFs can offer pressure-tunable, size-selective control of nanoparticle solvation and transport at easily obtainable temperature and pressure conditions. These capabilities provide clear advantages over conventional solvents and direct application to various nanomaterials processes, such as synthesis, separation, transport, and purification of nanocrystals.

AN - 67109565; 19289440 AB - UNLABELLEDAbsorbed-dose calculations provide a scientific basis for evaluating the biologic effects associated with administered radiopharmaceuticals. In cancer therapy, radiation dosimetry supports treatment planning, dose-response analyses, predictions of therapy effectiveness, and completeness of patient medical records. In this study, we evaluated the organ radiation absorbed doses from intravenously administered (111)In- and (90)Y-ibritumomab tiuxetan.METHODSTen patients (6 men and 4 women) with non-Hodgkin lymphoma, cared for at 3 different medical centers, were administered the tracer (111)In-ibritumomab tiuxetan and assessed using planar scintillation camera imaging at 5 time points and CT-organ volumetrics to determine patient-specific organ biokinetics and dosimetry. Explicit attenuation correction based on the transmission scan or transmission measurements provided the fraction of (111)In-administered activity in 7 major organs, the whole body, and remainder tissues over time through complete decay. Time-activity curves were constructed, and radiation doses were calculated using MIRD methods and implementing software.RESULTSMean radiation absorbed doses for (111)In- and for (90)Y-ibritumomab tiuxetan administered to 10 cancer patients are reported for 24 organs and the whole body. Biologic uptake and retention data are given for 7 major source organs, remainder tissues, and the whole body. Median absorbed dose values calculated by this method were compared with previously published dosimetry for ibritumomab tiuxetan and the product package insert.CONCLUSIONIn high-dose radioimmunotherapy, the importance of patient-specific dosimetry becomes obvious when the objective of treatment planning is to achieve disease cures, safely, by limiting radiation dose to any critical normal organ to its maximum tolerable value. Compared with the current package insert, we found differences in median absorbed dose by multiples of 24 in the kidneys, 1.8 in the red marrow, 0.65 in the liver, 0.077 in the intestinal wall, 0.30 in the lungs, 0.46 in the spleen, and 0.34 in the heart wall.

Corrected amplitudes can be used in ratios to discriminate between earthquakes and explosions. However, source effects remain that cannot easily be determined and applied as amplitude corrections, such as those due to depth, focal mechanism, local material property, and apparent stress variability. We develop a mathematical model to capture these near-source effects as random (unknown), giving an error partition of three sources: model inadequacy, station noise, and amplitude correlation. This mathematical model is the basis for a general multistation regional discriminant formulation. The standard error of the discriminant includes the variances of model inadequacy and station noise, along with amplitude correlation in its formulation. The developed methods are demonstrated for a collection of Nevada test site (NTS) events observed at regional stations (see Fig. 1). Importantly, the proposed formulation includes all corrected amplitude information through the construction of multistation discriminants. In contrast, previous studies have only computed discriminants from single stations having both P and S amplitudes. The proposed multistation approach has similarities to the well-established m (sub b) versus M (sub s) discriminant and represents a new paradigm for the regional discrimination problem.

Recent findings have shown a high level of spatial heterogeneity within a streambed and such heterogeneity directly affects surface- and ground-water exchange and can have ecological implications for biogeochemical transformations, nutrient cycling, organic matter decomposition, and reproduction of gravel spawning fish. In this study a detailed field investigation of K was conducted in two selected sites in Touchet River, a typical salmon spawning stream in arid south eastern Washington, USA. In-stream slug tests were conducted to determine K following the Bouwer and Rice method. For the upper and lower sites, each 50 m long and 9 m wide and roughly 20 m apart, a sampling grid of 5 m longitudinally and 3 m transversely was used. The slug tests were performed for each horizontal coordinate at 0.3-0.45, 0.6-0.75, 0.9-1.05 and 1.2-1.35 m depth intervals unless a shallower impenetrable obstruction was encountered. Additionally, water levels were measured to obtain vertical hydraulic gradient (VHG) between each two adjacent depth intervals. Results indicated that K ranged over three orders of magnitude at both the upper and lower sites and differed between the two sites. At the upper site, K did not differ significantly among different depth intervals based on nonparametric statistical tests for mean, median, and empirical cumulative distribution, but the spatial pattern of K varied among different depth intervals. At the lower site, K for the 0.3-0.45 m depth interval differed statistically from those at other depth intervals, and no similar spatial pattern was found among different depth intervals. Zones of upward and downward water flow based on VHG also varied among different depth intervals, reflecting the complexities of the water flow regime. Detailed characterization of the streambed as attempted in this study should be helpful in providing information on spatial variations of streambed hydraulic properties as well as surface- and ground-water interaction.

Lately, there has been increased interest in automating hydraulic conductivity laboratory techniques to reduce analysis time and improve data consistency. A new apparatus was developed that is able to measure hydraulic conductivity values with the constant-flux, constant-head, and falling-head methods in a fully automated fashion. The apparatus can be used for both packed columns and undisturbed field cores. The column design is such that water is forced to flow in a nominally one-dimensional manner through the porous medium. An analysis is initiated with a "smart search", yielding an estimate of the saturated hydraulic conductivity. The operator can use this estimated value to obtain conductivity values using one, two, or all three methods. Besides installing and removing the columns, no manual efforts are required. Hydraulic conductivity data for standard laboratory sands showed that application of the three methods resulted in similar results, indicating that external flow resistance was small. A comparison with literature data for the same sands, obtained with a constant-flux method, showed differences <9%.

Diesel particulate filters are presently the most efficient means to reduce these emissions. These filters typically trap particles in two basic modes: at the beginning of the exposure cycle the particles are captured in the filter holes, and at longer times the particles form a "cake" on which particles are trapped. Eventually the "cake" is removed by oxidation and the cycle is repeated. We have investigated the properties and behavior of two commonly used filters: silicon carbide (SiC) and cordierite (DuraTrap RC) by exposing them to nearly-spherical ammonium sulfate particles. We show that the transition from deep bed filtration to "cake" filtration can easily be identified by recording the change in pressure across the filters as a function of exposure. We investigated the performance of these filters as a function of flow rate and particle size and found that the filters have the highest filtration efficiencies for particles smaller than [not, vert, similar]80 nm and larger than [not, vert, similar]200 nm. A comparison between the experimental data and a simulation using incompressible lattice-Boltzmann model shows good qualitative agreement, but the model over-predicts the filter's trapping efficiency.

The ultimate goal is to provide cell designer and manufacture with a predictive methodology such that the life of the IC system can be managed and optimized through different coating thickness to meet the overall cell designed life. Crofer 22 APU is used as the example IC material system. The life of coated and uncoated Crofer 22 APU under isothermal cooling was predicted by comparing the predicted interfacial strength and the interfacial stresses induced by the cooling process from the operating temperature to room temperature, together with the measured oxide scale growth kinetics. It was found that the interfacial strength between the oxide scale and the Crofer 22 APU substrate decreases with the growth of the oxide scale, and that the interfacial strength for the oxide scale/spinel coating interface is much higher than that of the oxide scale/Crofer 22 APU substrate interface. As expected, the predicted life of the coated Crofer 22 APU is significantly longer than that of the uncoated Crofer 22 APU.

The composition of the polymer and relative amounts of polylactic acid, glycolic acid, and ethylene glycol were varied by controlling the precursor concentrations and reaction temperature. The gelation temperature could be systematically tailored from 15 to 34°C by increasing the concentration of polyethylene glycol in the graft copolymer. The gelation temperature also depended on the polymer molecular weight and concentration. This work has importance for the development of water soluble gels with tailored compositions and gelation temperatures for use in tissue engineering and as injectable depots for drug delivery.

We propose a risk-adjusted (RA) survival time CUSUM chart (RAST CUSUM) for monitoring a continuous, time-to-event variable that may be right-censored. Risk adjustment is accomplished using accelerated failure time regression models. We compare the average run length performance of the RAST CUSUM chart with the RA Bernoulli CUSUM chart using data from cardiac surgeries to motivate the details of the comparison. The comparisons show that the RAST CUSUM chart is more efficient at detecting a sudden increase in the odds of mortality than the RA Bernoulli CUSUM chart, especially when the fraction of censored observations is relatively low or when a small increase in the odds of mortality occurs. We also discuss the impact of the amount of training data used to estimate chart parameters as well as the implementation of the RAST CUSUM chart during prospective monitoring.

This is different from the trend of total rainfall observed in EC, which decreases in northern EC and increases in southern EC. To examine the cause of the light rain trends, we analyzed the long-term variability of atmospheric water vapor and its correlation with light rain events. Results show very weak relationships between large-scale moisture transport and light rain in EC. Because of human activities, pollutant emission has increased dramatically in China for the last few decades, leading to a significant reduction in visibility between 1960 and 2000. Cloud-resolving model simulations over EC show that aerosols corresponding to polluted conditions can significantly increase the cloud droplet number concentration (CDNC) and reduce droplet sizes compared to pristine conditions. This can lead to a significant decline in raindrop concentration and delay raindrop formation because smaller cloud droplets are less efficient in the collision and coalescence processes. Together with weaker convection, the precipitation frequency and amount are significantly reduced in the polluted case in EC. Satellite data also reveal higher CDNC and smaller droplet size over polluted land in EC relative to pristine regions, which is consistent with the model results. Observational evidences and simulations results suggest that the significantly increased aerosol concentrations produced by air pollution are at least partly responsible for the decreased light rain events observed in China over the past 50 years.

Mass concentrations, diurnal cycles, and size distributions of inorganic and organic species are similar to results from the CENICA supersite in April 2003 with organic aerosol (OA) comprising about half of the fine PM mass. Positive Matrix Factorization (PMF) analysis of the high resolution OA spectra identified three major components: chemically-reduced urban primary emissions (hydrocarbon-like OA, HOA), oxygenated OA (OOA, mostly secondary OA or SOA), and biomass burning OA (BBOA) that correlates with levoglucosan and acetonitrile. BBOA includes several very large plumes from regional fires and likely also some refuse burning. A fourth OA component is a small local nitrogen-containing reduced OA component (LOA) which accounts for 9% of the OA mass but one third of the organic nitrogen, likely as amines. OOA accounts for almost half of the OA on average, consistent with previous observations. OA apportionment results from PMF-AMS are compared to the PM sub(2.5) chemical mass balance of organic molecular markers (CMB-OMM, from GC/MS analysis of filters). Results from both methods are overall consistent. Both assign the major components of OA to primary urban, biomass burning/woodsmoke, and secondary sources at similar magnitudes. The 2006 Mexico City emissions inventory underestimates the urban primary PM sub(2.5) emissions by a factor of ~4, and it is ~16 times lower than afternoon concentrations when secondary species are included.

AN - 66906380; 19204484 AB - During the Capstone Depleted Uranium (DU) Aerosol Study, aerosols containing DU were produced inside unventilated armored vehicles (i.e., Abrams tanks and Bradley Fighting Vehicles) by perforation with large-caliber DU penetrators. These aerosols were collected and characterized, and the data were subsequently used to assess human health risks to personnel exposed to DU aerosols. The DU content of each aerosol sample was first quantified by radioanalytical methods, and selected samples, primarily those from the cyclone separator grit chambers, were analyzed radiochemically. Deposition occurred inside the vehicles as particles settled on interior surfaces. Settling rates of uranium from the aerosols were evaluated using filter cassette samples that collected aerosol as total mass over eight sequential time intervals. A moving filter was used to collect aerosol samples over time, particularly within the first minute after a shot. The results demonstrate that the peak uranium concentration in the aerosol occurred in the first 10 s after perforation, and the concentration decreased in the Abrams tank shots to about 50% within 1 min and to less than 2% after 30 min. The initial and maximum uranium concentrations were lower in the Bradley vehicle than those observed in the Abrams tank, and the concentration levels decreased more slowly. Uranium mass concentrations in the aerosols as a function of particle size were evaluated using samples collected in a cyclone sampler, which collected aerosol continuously for 2 h after perforation. The percentages of uranium mass in the cyclone separator stages ranged from 38 to 72% for the Abrams tank with conventional armor. In most cases, it varied with particle size, typically with less uranium associated with the smaller particle sizes. Neither the Abrams tank with DU armor nor the Bradley vehicle results were specifically correlated with particle size and can best be represented by their average uranium mass concentrations of 65 and 24%, respectively.

AN - 66906246; 19204486 AB - The impact of depleted uranium (DU) penetrators against an armored target causes erosion and fragmentation of the penetrators, the extent of which is dependent on the thickness and material composition of the target. Vigorous oxidation of the DU particles and fragments creates an aerosol of DU oxide particles and DU particle agglomerations combined with target materials. Aerosols from the Capstone DU aerosol study, in which vehicles were perforated by DU penetrators, were evaluated for their oxidation states using x-ray diffraction (XRD), and particle morphologies were examined using scanning electron microscopy/energy dispersive spectroscopy (SEM/EDS). The oxidation state of a DU aerosol is important as it offers a clue to its solubility in lung fluids. The XRD analysis showed that the aerosols evaluated were a combination primarily of U3O8 (insoluble) and UO3 (relatively more soluble) phases, though intermediate phases resembling U4O9 and other oxides were prominent in some samples. Analysis of particle residues in the micrometer-size range by SEM/EDS provided microstructural information such as phase composition and distribution, fracture morphology, size distribution, and material homogeneity. Observations from SEM analysis show a wide variability in the shapes of the DU particles. Some of the larger particles were spherical, occasionally with dendritic or lobed surface structures. Others appear to have fractures that perhaps resulted from abrasion and comminution, or shear bands that developed from plastic deformation of the DU material. Amorphous conglomerates containing metals other than uranium were also common, especially with the smallest particle sizes. A few samples seemed to contain small bits of nearly pure uranium metal, which were verified by EDS to have a higher uranium content exceeding that expected for uranium oxides. Results of the XRD and SEM/EDS analyses were used in other studies described in this issue of Health Physics to interpret the results of lung solubility studies and in selecting input parameters for dose assessments.

Six classes of solid hosts for uranium were identified. Preliminary sediment characterization was carried out using optical petrography, and electron microprobe analysis (EMPA) was used to locate materials that host uranium. All of the hosts are fine-grained and intergrown with other materials at spatial scales smaller than the analytical volume of the electron microprobe. A focused ion beam (FIB) was used to prepare electron-transparent specimens of each host for the transmission electron microscope (TEM). The hosts were identified as: (1) metatorbernite [Cu(UO (sub 2) ) (sub 2) (PO (sub 4) ) (sub 2) .8H (sub 2) O]; (2) coatings on sediment clasts comprised mainly of phyllosilicates; (3) an amorphous zirconium (oxyhydr)oxide found in clast coatings; (4) amorphous and poorly crystalline materials that line voids within basalt lithic fragments; (5) amorphous palagonite surrounding fragments of basaltic glass; and (6) Fe- and Mn-oxides. These findings demonstrate the effectiveness of combining EMPA, FIB, and TEM to identify solid-phase contaminant hosts. Furthermore, they highlight the complexity of U geochemistry in the Hanford vadose zone, and illustrate the importance of microscopic transport in controlling the fate of contaminant metals in the environment.

Contrasting the 1986 President Day and 1997 New Year Day events, differences in atmospheric stability have an influence on the spatial distribution of precipitation. Although both cases yielded similar precipitation, the 1997 case produced more runoff. Antecedent soil moisture, rainfall versus snowfall, and existing snowpack all seem to play a role, leading to a higher runoff to precipitation ratio for the 1997 case. This study underscores the importance of the atmospheric rivers and land surface conditions for predicting heavy precipitation and floods in the current and future climate of the western U.S. JF - Geophysical Research Letters AU - Leung, L Ruby AU - Qian, Yun AD - Pacific Northwest National Laboratory, Richland, Washington, USA Y1 - 2009/03// PY - 2009 DA - March 2009 PB - American Geophysical Union, 2000 Florida Ave., N.W.

In this study we simulated the deposition of soot aerosol on snow and the resulting impact on snowpack and the hydrological cycle in the western United States. A year-long simulation was performed using the chemistry version of the Weather Research and Forecasting model (WRF-Chem) to determine the soot deposition, followed by three simulations using WRF in meteorology-only mode, with and without the soot-induced snow albedo perturbations. The chemistry simulation shows large spatial variability in soot deposition that reflects the localized emissions and the influence of the complex terrain. The soot-induced snow albedo perturbations increase the surface net solar radiation flux during late winter to early spring, increase the surface air temperature, and reduce the snow accumulation and spring snowmelt. These effects are stronger over the central Rockies and southern Alberta, where soot deposition and snowpack overlap the most. The indirect forcing of soot accelerates snowmelt and alters stream flows, including a trend toward earlier melt dates in the western United States. The soot-induced albedo reduction initiates a positive feedback process whereby dirty snow absorbs more solar radiation, heating the surface and warming the air. This warming causes reduced snow depth and fraction, which further reduces the regional surface albedo for the snow-covered regions. For a doubled snow albedo perturbation, the change to surface energy and temperature is around 50 - 80%; however, snowpack reduction is nonlinearly accelerated. JF - Journal of Geophysical Research.

This paper summarizes the study's results and discusses its successes and lessons learned. The robust data from the Capstone DU Aerosol Study have provided a sound basis for assessing the inhalation exposure to DU aerosols and the dose and risk to personnel in combat vehicles at the time of perforation and to those entering immediately after perforation. The Human Health Risk Assessment provided a technically sound process for evaluating chemical and radiological doses and risks from DU aerosol exposure using well-accepted biokinetic and dosimetric models innovatively applied. An independent review of the study process and results is summarized, and recommendations for possible avenues of future study are provided by the authors and by other major reviews of DU health hazards.

In this article we discuss a workflow for the reconstruction of parts of the transcriptional regulatory network of the pathogenic bacterium Salmonella typhimurium based on the information contained in sets of microarray gene-expression data now available for that organism and describe our results obtained by following this workflow. The primary tool is one of the network-inference algorithms deployed in the Software Environment for Biological Network Inference (SEBINI). Specifically, we selected the algorithm called context likelihood of relatedness (CLR), which uses the mutual information contained in the gene-expression data to infer regulatory connections. The associated analysis pipeline automatically stores the inferred edges from the CLR runs within SEBINI and, upon request, transfers the inferred edges into either Cytoscape or the plug-in Collective Analysis of Biological Interaction Networks (CABIN) tool for further postanalysis of the inferred regulatory edges. The following article presents the outcome of this workflow, as well as the protocols followed for microarray data collection, data cleansing, and network inference. Our analysis revealed several interesting interactions, functional groups, metabolic pathways, and regulons in S. typhimurium.

The Capstone study consisted of two components: 1) generating, sampling, and characterizing DU aerosols by firing at and perforating combat vehicles, and 2) applying the source-term quantities and characteristics of the aerosols to the evaluation of doses and risks. This paper reviews the background of the study including the bases for the study, previous reviews of DU particles and health assessments from DU used by the U.S. military, the objectives of the study components, the participants and oversight teams, and the types of exposures it was intended to evaluate.

Present-day and preindustrial simulations are performed and compared for two scenarios. In the first scenario, the homogeneous freezing of sulfate particles dominates cirrus cloud formation in the upper troposphere (HOM). In the second scenario, both homogeneous and heterogeneous ice nucleation and their competition (HET) are allowed. In the HOM scenario, anthropogenic sulfate results in a global annual mean change of long-wave cloud forcing (LWCF) of 0.20 #+ 0.09 W m-2 and short-wave cloud forcing (SWCF) of 0.30 #+ 0.17 W m-2 and an increase of upper tropospheric/lower stratospheric (UT/LS) water vapor by ~10%. In the HET scenario, anthropogenic soot may increase global cirrus cloud cover by ~2% and UT/LS water vapor by 40% with a change in LWCF of 1.5 W m-2 (with 1.35 #+ 0.15 W m-2 from surface soot and 0.12 #+ 0.17 W m-2 from aircraft soot) if soot acts as efficient ice nuclei (IN) with a threshold ice nucleation i of 120 - 130%. Aerosol effects are most evident (larger than natural variability) over polar regions. However, their influence is significantly reduced if soot has a threshold i of 140% with an LWCF change of only 0.23 W m-2 (with 0.17 #+ 0.18 W m-2 from surface soot and 0.06 #+ 0.16 W m-2 from aircraft soot), and cloud forcing changes are statistically insignificant (less than the natural variability). Our results reinforce the importance of understanding ice nucleation on soot from the perspective of their global climate impact. JF - Journal of Geophysical Research.

By implementing an aerosol-dependent and a temperature- and supersaturation-dependent ice nucleation scheme and treating IN size distribution prognostically, the link between ice crystal and aerosol properties is established to study aerosol indirect effects. Two possible ice enhancement mechanisms, activation of droplet evaporation residues by condensation followed by freezing and droplet evaporation freezing by contact freezing inside out, are scrutinized by extensive comparisons with the in situ and remote sensing measurements. Simulations with either mechanism agree well with the in situ and remote sensing measurements of ice microphysical properties but liquid water content is slightly underpredicted. These two mechanisms give similar cloud properties, although ice nucleation occurs at very different rates and locations. Ice nucleation from activation of evaporation nuclei occurs mostly near cloud top areas, while ice nucleation from the drop freezing during evaporation has no significant location preference. Both ice enhancement mechanisms contribute dramatically to ice formation with ice particle concentration of 10 - 15 times higher relative to the simulation without either of them. Ice nuclei (IN) recycling from ice sublimation contributes significantly to maintaining concentrations of IN and ice particles in this case, implying an important role to maintain the observed long-term existence of mixed-phase clouds. Cloud can be very sensitive to IN initially but become much less sensitive as cloud evolves to a steady mixed-phase condition. JF - Journal of Geophysical Research.

Nonetheless, homology searches failed to recognize orthologs of previously described bacterial d- or l-lactate oxidizing enzymes (Escherichia coli genes dld and lldD) in any of the 13 analyzed genomes of Shewanella spp. By using comparative genomic techniques, we identified a conserved chromosomal gene cluster in Shewanella oneidensis MR-1 (locus tag: SO_1522-SO_1518) containing lactate permease and candidate genes for both d- and l-lactate dehydrogenase enzymes. The predicted d-LDH gene (dld-II, SO_1521) is a distant homolog of FAD-dependent lactate dehydrogenase from yeast, whereas the predicted l-LDH is encoded by 3 genes with previously unknown functions (lldEGF, SO_1520-SO_1518). Through a combination of genetic and biochemical techniques, we experimentally confirmed the predicted physiological role of these novel genes in S. oneidensis MR-1 and carried out successful functional validation studies in Escherichia coli and Bacillus subtilis. We conclusively showed that dld-II and lldEFG encode fully functional d-and l-LDH enzymes, which catalyze the oxidation of the respective lactate stereoisomers to pyruvate. Notably, the S. oneidensis MR-1 LldEFG enzyme is a previously uncharacterized example of a multisubunit lactate oxidase. Comparative analysis of >400 bacterial species revealed the presence of LldEFG and Dld-II in a broad range of diverse species accentuating the potential importance of these previously unknown proteins in microbial metabolism.

The charge state significantly influences the conformation and the binding energy between vancomycin antibiotic and bacterial cell-wall analogue peptides (see figure). Surface-induced dissociation (SID) studies provide a quantitative comparison between the stabilities of different charge states of the complex. In this study we examined the effect of the charge state on the energetics and dynamics of dissociation of the noncovalent complex between the vancomycin and the cell-wall peptide analogue N,N-diacetyl-L-Lys-D-Ala-D-Ala (V-Ac2LKdAdA). The binding energies between the vancomycin and the peptide were obtained from the RRKM (Rice, Ramsperger, Kassel, Marcus) modeling of the time- and energy-resolved surface-induced dissociation (SID) experiments. Our results demonstrate that the stability of the complex towards fragmentation increases in the order: doubly protonated> 0. The traditional interpretation of the I = PAT equation reflects the optimistic belief that technological innovation, particularly improvements in eco-efficiency, will significantly reduce the technology (T) factor, and thereby result in a corresponding decline in impact (I). Unfortunately, this interpretation of the I = PAT equation ignores the effects of technological change on the other two factors: population (P) and per capita affluence (A). A more heuristic formulation of this equation is I = P(T).A(T).T in which the dependence of P and A on T is apparent. From historical evidence, it is clear that technological revolutions (tool-making, agricultural, and industrial) have been the primary driving forces behind successive population explosions, and that modern communication and transportation technologies have been employed to transform a large proportion of the world's inhabitants into consumers of material- and energy-intensive products and services. In addition, factor analysis from neoclassical growth theory and the rebound effect provide evidence that science and technology have played a key role in contributing to rising living standards. While technological change has thus contributed to significant increases in both P and A, it has at the same time brought about considerable eco-efficiency improvements. Unfortunately, reductions in the T-factor have generally not been sufficiently rapid to compensate for the simultaneous increases in both P and A. As a result, total impact, in terms of energy production, mineral extraction, land-use and CO2 emissions, has in most cases increased with time, indicating that industrial society is nevertheless moving towards collapse. The belief that continued and even accelerated scientific research and technological innovation will automatically result in sustainability and avert collapse is at best mistaken. Innovations in science and technology will be necessary but alone will be insufficient for sustainability. Consequently, what is most needed are specific policies designed to decrease total impact, such as (a) halting population growth via effective population stabilization plans and better access to birth control methods, (b) reducing total matter-energy throughput and pollution by removing perverse subsidies, imposing regulations that limit waste discharges and the depletion of non-renewable resources, and implementing ecological tax reform, and (c) moving towards a steady-state economy in which per-capita affluence is stabilized at lower levels by replacing wasteful conspicuous material consumption with social alternatives known to enhance subjective well-being. While science and technology must play an important role in the implementation of these policies, none will be enacted without a fundamental change in society's dominant values of growth and exploitation. Thus, value change is the most important prerequisite for avoiding global collapse.

AN - 69714931; 18791025 AB - Because of their cell surface locations, the outer membrane c-type cytochromes MtrC and OmcA of Shewanella oneidensis MR-1 have been suggested to be the terminal reductases for a range of redox-reactive metals that form poorly soluble solids or that do not readily cross the outer membrane. In this work, we determined the kinetics of reduction of a series of Fe(III) complexes with citrate, nitrilotriacetic acid (NTA), and EDTA by MtrC and OmcA using a stopped-flow technique in combination with theoretical computation methods. Stopped-flow kinetic data showed that the reaction proceeded in two stages, a fast stage that was completed in less than 1 s, followed by a second, relatively slower stage. For a given complex, electron transfer by MtrC was faster than that by OmcA. For a given cytochrome, the reaction was completed in the order Fe-EDTA > Fe-NTA > Fe-citrate. The kinetic data could be modeled by two parallel second-order bimolecular redox reactions with second-order rate constants ranging from 0.872 microM(-1) s(-1) for the reaction between MtrC and the Fe-EDTA complex to 0.012 microM(-1) s(-1) for the reaction between OmcA and Fe-citrate. The biphasic reaction kinetics was attributed to redox potential differences among the heme groups or redox site heterogeneity within the cytochromes. The results of redox potential and reorganization energy calculations showed that the reaction rate was influenced mostly by the relatively large reorganization energy. The results demonstrate that ligand complexation plays an important role in microbial dissimilatory reduction and mineral transformation of iron, as well as other redox-sensitive metal species in nature.

The surface properties of NAu-2 were independently characterized to determine its fixed charge and amphoteric site density in order to interpret the Fe (super 2+) sorption data. Fe (super 2+) sorption to NAu-2 was strongly dependent on pH and ionic strength, reflecting the coupled effects of Fe (super 2+) sorption through ion exchange and surface complexation reactions. Fe (super 2+) sorption to NAu-2 increased with increasing pH from pH 2.5 to 4.5, remained constant from pH 4.5 to 7.0, increased again with further increase of pH from pH 7.0 to 8.5, and reached a maximum above pH 8.5. The Fe (super 2+) sorption below pH 7.0 increased with decreasing ionic strength. The differences of Fe (super 2+) sorption at different ionic strengths, however, diminished with increasing equilibration time. The Fe (super 2+) sorption from pH 4.5 to 7.0 increased with increasing equilibration time up to 35 days and showed stronger kinetic behavior in higher ionic strength solutions. The kinetic uptake of Fe (super 2+) onto NAu-2 is consistent with a surface precipitation mechanism although our measurements were not able to identify secondary precipitates. An equilibrium model that integrates ion exchange, surface complexation and aqueous speciation reactions reasonably well describes the Fe (super 2+) sorption data as a function of pH, ionic strength, and Fe (super 2+) concentration measured at 24 h of equilibration. Model calculations show that the species Fe(OH) (super +) was required to describe Fe (super 2+) sorption above pH 8.0 satisfactorily. Overall, this study demonstrated that Fe (super 2+) sorption to NAu-2 is affected by complex equilibrium and kinetic processes, likely caused by surface precipitation reactions.

Healing began within 7 d, wounds were completely closed after 14 d, and no mortality occurred. The healing process followed a pattern in which tissue first thickened around the opening (7-14 d), scarring of the ruptured area occurred, and evidence of the wound ultimately disappeared (21-28 d). The healing observed in juvenile rainbow trout suggests that swim bladder rupture does not result in direct mortality as was hypothesized; however, the indirect effects of swim bladder injury (e.g., a decreased ability to swim efficiently) may lead to mortality by predation or other natural phenomena that were not observable in this study.

Samples collected during the acetate amendment experiment were analyzed for aqueous concentrations of Fe(II), sulfate, sulfide, acetate, U(VI), and *d34S of sulfate and sulfide to explore the utility of sulfur isotopes as indicators of in situ acetate amended sulfate and uranium bioreduction processes. Enrichment of up to 7 in *d34S of sulfate in down-gradient monitoring wells indicates a transition to elevated bacterial sulfate reduction. A depletion in Fe(II), sulfate, and sulfide concentrations at the height of sulfate reduction, along with an increase in the *d34S of sulfide to levels approaching the *d34S values of sulfate, indicates sulfate limited conditions concurrent with a rebound in U(VI) concentrations. Upon cessation of acetate amendment, sulfate and sulfide concentrations increased, while *d34S values of sulfide returned to less than -20 and sulfate *d34S decreased to near-background values, indicating lower levels of sulfate reduction accompanied by a corresponding drop in U(VI). Results indicate a transition between electron donor and sulfate-limited conditions at the height of sulfate reduction and suggest stability of biogenic FeS precipitates following the end of acetate amendment.

Therefore, contaminants in the bypassed areas may not be contacted by the amendments in the remedial fluid, which may significantly prolong remediation operations. Laboratory experiments and numerical studies have been conducted to investigate the use of a shear-thinning polymer (Xanthan gum) to improve access to low-permeability zones in heterogeneous systems. The chemicals sodium mono-phosphate and the surfactant MA-80 were used as the remedial amendments. The impact of polymer concentration, fluid injection rate, and permeability contrast in the heterogeneous systems has been studied in a series of eleven two-dimensional flow cell experiments. The Subsurface Transport over Multiple Phases (STOMP) simulator was modified to include polymer-induced shear-thinning effects. The experimental and simulation results clearly show that using the polymer leads to an enhanced delivery of remedial amendments to lower-permeability zones and an increased sweeping efficiency. An added benefit of using the polymer is the stabilization of the displacing front when density differences exist between displaced and displacing fluids. The modified STOMP simulator was able to predict the experimental observed fluid displacing behavior well and might be used to predict subsurface remediation performance when a shear-thinning fluid is used to remediate a heterogeneous system at larger scales.

13266471 AB - The results of a field experiment designed to test the effectiveness of a novel approach for long-term, in situ bioimmobilization of toxic and soluble Cr(VI) in groundwater using a hydrogen release compound (HRC)a slow release glycerol polylactateare described. The field experiment was conducted at the Hanford Site (Washington), a U.S. Department of Energy nuclear production facility, using a combination of hydrogeological, geophysical, geochemical, and microbiological measurements and analyses of water samples and sediments. The results of this experiment show that a single HRC injection into groundwater stimulates an increase in biomass, a depletion of terminal electron acceptors O2, NO3-, and SO42-, and an increase in Fe2+, resulting in a significant decrease in soluble Cr(VI). The Cr(VI) concentration has remained below the background concentration in the downgradient pumping/monitoring well, and below the detection limit in the injection well for more than 3 years after the HRC injection. The degree of sustainability of Cr(VI) reductive bioimmobilization under different redox conditions at this and other contaminated sites is currently under study.

AN - 69482257; 18656485 AB - Sequenced genomes of dissimilatory sulfur-oxidizing and sulfate-reducing bacteria containing genes coding for DsrAB, the enzyme dissimilatory sulfite reductase, inevitably also contain the gene coding for the 12-kDa DsrC protein. DsrC is thought to have a yet unidentified role associated with the activity of DsrAB. Here we report the solution structure of DsrC from the sulfur-oxidizing purple sulfur bacterium Allochromatium vinosum determined with NMR spectroscopy in reducing conditions, and we describe the redox behavior of two conserved cysteine residues upon transfer to an oxidizing environment. In reducing conditions, the DsrC structure is disordered in the highly conserved carboxy-terminus. We present multiple lines of evidence that, in oxidizing conditions, a strictly conserved cysteine (Cys111) at the penultimate position in the sequence forms an intramolecular disulfide bond with Cys100, which is conserved in DsrC in all organisms with DsrAB. While an intermolecular Cys111-Cys111 disulfide-bonded dimer is rapidly formed under oxidizing conditions, the intramolecularly disulfide-bonded species (Cys100-Cys111) is the thermodynamically stable form of the protein under these conditions. Treatment of the disulfidic forms with reducing agent regenerates the monomeric species that was structurally characterized. Using a band-shift technique under nondenaturing conditions, we obtained evidence for the interaction of DsrC with heterohexameric DsrEFH, a protein encoded in the same operon. Mutation of Cys100 to serine prevented formation of the DsrC species assigned as an intramolecular disulfide in oxidizing conditions, while still allowing formation of the intermolecular Cys111-Cys111 dimer. In the reduced form, this mutant protein still interacted with DsrEFH. This was not the case for the Cys111Ser and Cys100Ser/Cys111Ser mutants, both of which also did not form protein dimers. Our observations highlight the central importance of the carboxy-terminal DsrC cysteine residues and are consistent with a role as a sulfur-substrate binding/transferring protein, as well as with an electron-transfer function via thiol-disulfide interchanges.

2011-073698 AB - Reactions at hematite-water interfaces affect contaminant fate and transport, partially control biogeochemical iron cycling, and fractionate iron isotopes. The ability to predict and quantify these and other important processes in nature requires a fundamental understanding of the structure of hematite-water interfaces and the reactions that occur here. The ordering of water at hematite surfaces and the structural transformations these surfaces undergo as a result of reaction with aqueous Fe(II) have been characterized. Water takes on an ordered arrangement near the hematite (012) and (110) surfaces, with the degree of ordering declining away from the surface on the length scale of approximately 1-2 nanometers. Fe(II) induces orientation-dependent structural changes to hematite surfaces that suggest growth occurs on (001) and dissolution on (110) and (012). This behavior occurs under both neutral (pH 7) and acidic (pH 3) conditions. Fe(II) presumably serves a catalytic role, transporting Fe between different surfaces through solution with electrons conducting back through the hematite structure in the reverse direction. This dynamic interfacial redox process may be responsible for the recent observations of electron transfer and isotope fractionation in Fe(II)-iron oxide systems.

Particle volumes are then converted to mass loads by using particle densities that are commonly estimated from measured mobility and vacuum aerodynamic diameters, assuming that the particles are spherical. For aspherical particles, these assumptions can introduce significant errors. We present in this work a new method that can be applied to any particle system to determine in real time whether the particles are spherical or not. We use our second-generation single particle mass spectrometer (SPLAT II) to measure with extremely high precision the vacuum aerodynamic size distributions of particles that are classified by differential mobility analyzer and demonstrate that the line shape of these vacuum aerodynamic size distributions provide a way to unambiguously distinguish between spherical and aspherical particles. Moreover, the very same experimental system is used to obtain the size, density, composition, and dynamic shape factors of individual particles. We present an application of this method to secondary organic aerosols that are formed as a result of ozonolysis of *a-pinene in the presence and absence of an OH scavenger and find these particles to be spherical with densities of 1.198 c 0.004 and 1.213 c 0.003 g cm-3, respectively.

Brecciated tops and bases of individual flows form regional aquifers, and are potential sites for sequestration of gigatons of CO2 in areas where the basalts contain unpotable water and are at depths greater than 800 m. In laboratory experiments, these basalts react with formation water and supercritical CO2 to precipitate carbonates, thus adding a potential mineral trapping mechanism to the standard dissolution and hydrodynamic trapping mechanisms of most other types of CO2 sequestration reservoirs. The DOE's Big Sky Regional Carbon Sequestration Partnership has proposed a field test of capacity, integrity, and geochemical reactivity of basalt reservoirs near Wallula, Washington, and has begun surface and subsurface site characterization in preparation for drilling a characterization/injection test well. Acquisition of surface-based seismic data is important in subsurface characterization. Seismic data are highly desirable for determining subsurface suitability of a proposed site, building conceptual and numerical reservoir models, and for time-lapse monitoring of injected CO2. Traditional surface seismic methods have had little success in obtaining usable data within basalt layers, as a consequence of severe energy scattering and interfering wave modes that degrade image quality or misplace geologic features. An innovative multicomponent (3C) 2D seismic swath experiment at the Wallula site is providing a long-sought breakthrough in improving seismic signal/noise and in imaging subsurface basalt geology. Processing of the 6.5 km, 5 line 3C swath included building an elastic wavefield model and identifying and separating seismic wave modes. The resulting P-P seismic images demonstrate a succession of unfaulted basalt layers suitable for wellbore characterization and testing. Our 3C2D seismic experiment produced successful surface-based seismic imaging of intra-basalt geology and provides a critical key for development of seismic technologies for sequestration of greenhouse CO2 in basalts.

AN - 69638654; 18719237 AB - In this work, we investigate (3)He magnetic resonance imaging as a noninvasive morphometric tool to assess emphysematous disease state on a local level. Emphysema was induced intratracheally in rats with 25 U/100 g body wt of porcine pancreatic elastase dissolved in 200 microl saline. Rats were then paired with saline-dosed controls. Nine three-dimensional (3D) (3)He diffusion-weighted images were acquired at 1, 2, or 3 wk postdose, after which the lungs were harvested and prepared for histological analysis. Recently introduced indexes sensitive to the heterogeneity of the air space size distribution were calculated. These indexes, D(1) and D(2), were derived from the moments of the mean equivalent airway diameters. Averaged over the entire lung, it is shown that the average (3)He diffusivity (D(ave)) correlates well with histology (R = 0.85, P < 0.0001). By matching small (0.046 cm(2)) regions in (3)He images with corresponding regions in histological slices, D(ave) correlates significantly with both D(1) and D(2) (R = 0.88 and R = 0.90, respectively, with P < 0.0001). It is concluded that (3)He MRI is a viable noninvasive morphometric tool for localized in vivo emphysema assessment.

Bioreduction experiments were conducted with uranyl acetate as the electron acceptor and sodium lactate as the electron donor under resting cell conditions in a 30 mM NaHCO (sub 3) buffer, and in a PIPES-buffered artificial groundwater (PBAGW). MR-1 was cultured in batch mode in a defined minimal medium with a specified air-to-medium volume ratio such that electron acceptor (O (sub 2) ) limiting conditions were reached just when cells were harvested for subsequent experiments. The rate of U(VI) bioreduction was manipulated by varying the cell density and the incubation temperature (1.0X10 (super 8) cell ml (super -1) at 20 degrees C or 2.0X10 (super 8) cell ml (super -1) at 37 degrees C) to generate U(IV) solids at "fast" and "slow" rates in the two different buffers. The presence of Ca in PBAGW buffer altered U(VI) speciation and solubility, and significantly decreased U(VI) bioreduction kinetics. High resolution transmission electron microscopy was used to measure uraninite particle size distributions produced under the four different conditions. The most common primary particle size was 2.9-3.0 nm regardless of U(VI) bioreduction rate or background electrolyte. Extended X-ray absorption fine-structure spectroscopy was also used to estimate uraninite particle size and was consistent with TEM results. The reactivity of the biogenic uraninite products with dissolved oxygen was tested, and neither U(VI) bioreduction rate nor background electrolyte had any statistical effect on oxidation rates. With MR-1, uraninite particle size was not controlled by the bioreduction rate of U(VI) or the background electrolyte. These results for MR-1, where U(VI) bioreduction rate had no discernible effect on uraninite particle size or oxidation rate, contrast with our recent research with Shewanella putrefaciens CN32, where U(VI) bioreduction rate strongly influenced both uraninite particle size and oxidation rate. These two studies with Shewanella species can be viewed as consistent if one assumes that particle size controls oxidation rates, so the similar uraninite particle sizes produced by MR-1 regardless of U(VI) bioreduction rate would result in similar oxidation rates. Factors that might explain why U(VI) bioreduction rate was an important control on uraninite particle size for CN32 but not for MR-1 are discussed.

Perennial systems offer the potential to improve soil quality, reduce erosion, and improve water, air, and habitat quality. However, annual cropping systems provide higher productivity and allow producers more profit producing opportunities through greater crop flexibility. No-till systems may provide similar soil quality and ecosystems services as perennial systems. Additional issues must be addressed for sustainable bioenergy feedstock production systems. The first is in-depth water, energy and economic analyses of systems involving crop species of interest. Such analyses are important because the production inputs and conversion rates influence the energy balance, economic benefits, and life-cycle attributes of each system and are necessary for producers and policy makers to make appropriate decisions regarding adoption of select and attainable systems for large-scale biofuel production. The second issue is the impact biomass removal on soil, water and other natural resources. These issues required research to determine the appropriate management strategies (species selection, cropping system, and harvest intensity) for sustainable and compatible systems.

The most common naturally-occurring uranyl-phosphates, the autunite group minerals (X (sub 3-n) (super (n)+) [(UO (sub 2) )(PO (sub 4) )] (sub 2) . xH (sub 2) O), have been identified as the long-term U-controlling phases in many systems of environmental interest. The autunite-type sheet contains uranyl square bipyramids linked to phosphate tetrahedra, in which each equatorial vertex of the uranyl bipyramid is shared with a different phosphate tetrahedron, and each tetrahedron is in turn linked to four distinct uranyl polyhedra. Because of the crystallographic distribution of periodic bond chains in the autunite structure, we propose that the dissolution rate of autunite minerals measured from the sheet edge will be significantly greater than that measured on the basal autunite face (001). Previous results have also shown that pH-sensitive differences in interlayer cation release rate (e.g., Na (super +) or Ca (super 2) ) may derive from different reaction mechanisms (ion exchange versus matrix dissolution). In order to test this working hypothesis, we have conducted dissolution experiments using single crystals of natural autunite mounted in buffered flow-through reactors over a range of circumneutral to alkaline pH conditions and variable temperatures < or = 70 degrees C. Using techniques previously employed for silicate and carbonate minerals, dissolution rates were measured using high resolution vertical scanning interferometry by maintaining pristine reference surfaces under the conditions of interest. This approach has been used to quantify the difference in autunite mineral dissolution rates as measured from the edge versus the face of the mineral.

Photosynthesis-irradiance experiments and depth distribution field studies indicated that eelgrass productivity was maximum at a photosynthetic photon flux density (PPFD) of about 350-550 [mu]mol quanta m super(-2) s super(-1). Winter plants had approximately threefold greater net apparent primary productivity rate at the same irradiance as summer plants. Growth studies using artificial shading as well as field monitoring of light and eelgrass growth indicated that long-term survival required at least 3 mol quanta m super(-2) day super(-1) on average during spring and summer (i.e., May-September), and that growth was saturated above about 7 mol quanta m super(-2) day super(-1). We conclude that non- light-limited growth of eelgrass in the Pacific Northwest requires an average of at least 7 mol quanta m super(-2) day super(-1) during spring and summer and that long-term survival requires a minimum average of 3 mol quanta m super(-2) day super(- 1).

The objective of this study was to address the need for validated sampling and analysis methods called out by the General Accounting Office and others to systematically compare the collection efficiency of various swabs and wipes for collection of bacterial endospores from five different surfaces, both porous and nonporous. This study was also designed to test the collection and extraction solutions used for endospore recovery from swabs and wipes.Methods and Results:Eight collection tools, five swabs and three wipes, were used. Three collection/preservation solutions were evaluated: an ink jet aerosol generator was used to apply Bacillus subtilis endospores to five porous and nonporous surfaces. The collection efficiencies of the swabs and wipes were compared using a statistical multiple comparison analysis.Conclusions:The ScottPure+ wipe had the highest collection efficiency and phosphate-buffered saline (PBST) with 0.3% Tween was the best collection solution of those tested.Significance and Impact of the Study:Validated sampling for potential biological warfare is of significant importance and this study answered some relevant questions.

Development of experimental methods and measurements for the characterization of diffusion in fractured glass media is necessary for the design and performance assessment of glassified radionuclear waste disposal facilities. We report on the use of time-lag diffusion experimental method to assess the diffusion behavior of three different solutes (Cs, Sr, and pentafluoro benzoic acid) in fractured, immobilized low activity waste (ILAW) glass forms. A fractured media time-lag diffusion experimental apparatus, which allows the measurement of diffusion coefficients, has been designed and built for this purpose. Use of time-lag diffusion method, a considerably easier experimental method than the other available methods, was not previously demonstrated for measuring diffusion in fractured waste glass media. Hydraulic conductivity, porosity, and diffusion coefficients of a solute were experimentally measured in fractured glass blocks using this method for the first time. Results agree with the range of properties reported for similar rock media earlier, indicating that the time-lag experimental method can effectively characterize the diffusion coefficients of fractured ILAW glass media. Data presented are rare and useful for the design of vitrified glass disposal facilities.

The properties and hence stability of uraninite are dependent on its size, structure, and composition. In this study, the local-, intermediate-, and long-range molecular-scale structure of nanoscale uraninite produced by Shewanella oneidensis strain MR-1 was investigated using EXAFS, SR-based powder diffraction and TEM. The uraninite products were found to be structurally homologous with stoichiometric UO2 under all conditions considered. Significantly, there was no evidence for lattice strain of the biogenic uraninite nanoparticles. The fresh nanoparticles were found to exhibit a well-ordered interior core of diameter ca. 1.3 nm and an outer region of thickness ca 0.6 nm in which the structure is locally distorted. The lack of nanoparticle strain and structural homology with stoichiometric UO2 suggests that established thermodynamic parameters for the latter material are an appropriate starting point to model the behavior of nanobiogenic uraninite. The detailed structural analysis in this study provides an essential foundation for subsequent investigations of environmental samples.

Surface complexation model (SCM) calculations for U(VI) sorption, using only U(VI) surface-reaction constants obtained from U(VI) sorption data on freshly synthesized ferrihydrite at different pHs, were similar to the measured U(VI) sorption results on pure synthetic ferrihydrite and on HFS with high contents of ferrihydrite (5wt%) added. However, the SCM prediction using only U(VI) sorption reactions and constants for synthetic ferrihydrite overestimated U(VI) sorption on the natural HFS or HFS with addition of low amounts of added ferrihydrite (1 wt% added). Over-predicted U(VI) sorption was attributed to reduced reactivity of natural ferrihydrite present in Hanford Site sediments, compared to freshly prepared synthetic ferrihydrite. Even though the SCM general composite (GC) approach is considered to be a semi-quantitative estimation technique for contaminant sorption, which requires systematic experimental data on the sorbent-sorbate system being studied to obtain credible SCM parameters, the general composite SCM model was still found to be a useful technique for describing U(VI) sorption on natural sediments. Based on U(VI) batch sorption results, two simple U(VI) monodentate surface species, SO_UO (sub 2) HCO (sub 3) and SO_UO (sub 2) OH on ferrihydrite and phyllosillicate in HFS, respectively, can be successfully used to describe U(VI) sorption onto Hanford Site sediment contacting varying geochemical solutions.

Experiments were performed with three prototypic nuclear waste glasses that span a wide compositional range, which covers, with high probability, the expected processing composition range for candidate immobilized low-activity waste (ILAW) glasses. Comparison of the B to Na release rates for one glass was incongruent at 23 and 40 degrees C, and pH (23 degrees C)=7.0 and 8.0, suggesting two distinct mechanisms are responsible for the Na (super +) release, namely Na (super +) -H (super +) ion-exchange and matrix dissolution. Matrix dissolution became the dominant dissolution mechanism for all glasses at the forward rate and pH values greater than 9.0 as evident by the congruent release of Al, B, Na and Si to solution. By combining the results collected for each ILAW glass at pH values greater than 9.0, pH and temperature-dependent rate law parameters were determined for Al, B, Na and Si release. A comparison of the pH power-law coefficient for Al, B, Na and Si at each temperature suggest that eta does not depend on temperature within experimental error and suggests the release of these elements into solution is controlled by the same dissolution mechanism at the forward rate of reaction. The activation energies (E (sub a) ), based on B release, range from 52+ or -4 to 56+ or -6 kJ/mol which suggest that dissolution is a surface-controlled reaction mechanism. The data presented in this manuscript suggest that for these three ILAW glasses the chemical durability for each glass is similar under these test conditions. A lack of compositional dependence on the forward dissolution rate is observed even though there is as much as a 39 kJ/mol difference in the free energy of hydration (Delta G (sub hyd) ) among the borosilicate waste glasses tested. This similarity in the forward dissolution rate despite the large Delta G (sub hyd) difference is almost certainly because these glasses have similar, if not identical, polymerization states. This is evident from the almost identical (super 29) Si chemical shifts for each of these glasses. The polymerization state is an indication of the number of framework SiO (sub 4) linkages contained in the glass network. In general, the greater the number of framework SiO (sub 4) linkages the more durable the glass. Finally, in agreement with previous work, these results suggest breakage of the Si-O bond is the rate-determining dissolution mechanism under alkaline conditions [pH (23 degrees C)>9.0] far from saturation with respect to an alteration phase or phases.

The analysis is conducted using the Impact of Sector Energy Technologies (ImSET) model, a special-purpose 188-sector input-output model of the U.S. economy designed specifically to evaluate the impacts of energy efficiency investments and saving. For the analysis described in the paper, ImSET was amended to provide estimates of sector-by-sector capital requirements and investment. In the scenario of the Fiscal Year (FY) 2005 Building Technologies (BT) program, the technologies and building practices being developed and promoted by the BT program have the potential to save about 2.9x1015 Btu in buildings by the year 2030, about 27% of the expected growth in building energy consumption by the year 2030. The analysis reported in the paper finds that, by the year 2030, these savings have the potential to increase employment by up to 446,000 jobs, increase wage income by $7.8 billion, reduce needs for capital stock in the energy sector and closely related supporting industries by about $207 billion (and the corresponding annual level of investment by $13 billion), and create net capital savings that are available to grow the nation's future economy.

This paper considers how to determine the optimum number of increments to use in composite sampling. Composite sampling terminology and theory are outlined and a method is developed which accounts for different sources of variation in compositing and data analysis. This method is used to define and understand the process of determining the optimum number of increments that should be used in forming a composite. The blending variance is shown to have a smaller range of possible values than previously reported when estimating the number of increments in a composite sample. Accounting for differing levels of the blending variance significantly affects the estimated number of increments.

Metallic uranium shot, 0.5-1 mm diameter, was reacted with ammonium carbonate-hydrogen peroxide solutions ranging in concentration from 0.13 M to 1.0 M carbonate and 0.50 M to 2.0 M peroxide. The dissolution rate was calculated from the reduction in bead mass, and independently by uranium analysis of the solution. The calculated dissolution rate ranged from about 4 X 10-3 to 8 X 10-3 mm/h, dependent primarily on the peroxide concentration. Hydrogen analysis of the etched beads showed that no detectable hydrogen was introduced into the uranium metal by the etching process.

The sediment was a coarse-textured alluvial flood deposit containing significant mass percentage of river cobble. U(VI) was, however, only associated with its minor fine-grained (<2 mm) mass fraction. U(VI) desorption was investigated both from the field-textured sediment using a large column (80 cm length by 15 cm inner diameter) and from its <2 mm U(VI)-associated mass fraction using a small column (10 cm length by 3.4 cm inner diameter). Dynamic advection conditions with intermittent flow and stop-flow events of variable durations were employed to investigate U(VI) desorption kinetics and its scale dependence. A multicomponent kinetic model that integrated a distributed rate of mass transfer with surface complexation reactions successfully described U(VI) release from the fine-grained U(VI)-associated materials. The field-textured sediment in the large column displayed dual-domain tracer-dependent mass transfer properties that affected the breakthrough curves of bromide, pentafluorobenzoic acid (PFBA), and tritium. The tritium breakthrough curve showed stronger nonequilibrium behavior than did PFBA and bromide and required a larger immobile porosity to describe. The dual-domain mass transfer properties were then used to scale the kinetic model of U(VI) desorption developed for the fine-grained materials to describe U(VI) release and reactive transport in the field-textured sediment. Numerical simulations indicated that the kinetic model that was integrated with the dual-domain properties determined from tracer PFBA and Br best described the experimental results. The kinetic model without consideration of the dual-domain properties overpredicted effluent U(VI) concentrations, while the model based on tritium mass transfer underpredicted the rate of U(VI) release. Overall, our results indicated that the kinetics of U(VI) release from the field-textured sediment were different from that of its fine-grained U(VI)-associated mass fraction. However, the desorption kinetics measured on the U(VI)-containing mass fraction could be scaled to describe U(VI) reactive transport in the contaminated field-textured sediment after proper consideration of the physical transport properties of the sediment. The research also demonstrated a modeling approach to integrate geochemical processes into field-scale reactive transport models.

The maturation and increased application of autonomous underwater vehicles (AUVs) in aquatic environments allows systematic data collection on these model-relevant scales. The goal of this study was to apply a fine-scale circulation and transport model (Delft3D) to improve AUV mission planning and use data collected by the AUV to evaluate and improve model performance. A dye release was conducted in a tidally dominated embayment, and a planning phase model based on the best available data was used as a baseline for evaluation and for AUV mission planning (forecast). The planning phase model correctly predicted the general shape and direction of the dye plume and allowed for successful mission planning. Subsequently, bathymetry data collected by the AUV was incorporated into the model (hindcast), with temperature and salinity collected before the experiment. Comparisons with fluorometer measurements from the AUV indicate that the model effectively predicted the edges of the plume and centerline location. The location was also confirmed by remote sensing from an aircraft. Thermal stratification was found to be an important fate mechanism in the final model, and the results demonstrate the integration of observational data sets for small, short-duration surface-contaminant releases. This study highlights the strength of a phased, iterative approach with observation platforms and may serve as a guide toward improving the performance and evaluation of future coastal hydrodynamic and transport modeling efforts.

Secondary organic aerosol (SOA) produced by ozonation of d-limonene, as well as several organic molecules with functional groups typical for OA constituents, were extracted in methanol, d3-methanol, acetonitrile, and d3-acetonitrile to investigate the extent and relative rates of reactions between analyte and solvent. High resolution ESI-MS showed that reactions of carbonyls with methanol produce significant amounts of hemiacetals and acetals on time scales ranging from several minutes to several days, with the reaction rates increasing in acidified solutions. Carboxylic acid groups were observed to react with methanol resulting in the formation of esters. In contrast, acetonitrile extracts showed no evidence of reactions with analyte molecules, suggesting that acetonitrile is the preferred solvent for SOA extraction. The use of solvent-analyte reactivity as a tool for the improved characterization of functional groups in complex organic mixtures was demonstrated. Direct comparison between mass spectra of the same SOA samples extracted in methanol versus acetonitrile was used to estimate the lower limits for the relative fractions of carbonyls (>=42%) and carboxylic acids (>=55%) in d-limonene SOA.

Developing a full understanding of the major sources of Pb and other metals is critical to controlling these emissions. During the March, 2006 MILAGRO campaign, single particle measurements in Mexico City revealed the frequent appearance of particles internally mixed with Zn, Pb, Cl, and P. Pb concentrations were as high as 1.14 *mg/m3 in PM10 and 0.76 *mg/m3 in PM2.5. Real time measurements were used to select time periods of interest to perform offline analysis to obtain detailed aerosol speciation. Many Zn-rich particles had needle-like structures and were found to be composed of ZnO and/or Zn(NO3)2.6H2O. The internally mixed Pb-Zn-Cl particles represented as much as 73% of the fine mode particles (by number) in the morning hours between 2-5 am. The Pb-Zn-Cl particles were primarily in the submicrometer size range and typically mixed with elemental carbon suggesting a combustion source. The unique single particle chemical associations measured in this study closely match signatures indicative of waste incineration. Our findings also show these industrial emissions play an important role in heterogeneous processing of NOy species. Primary emissions of metal and sodium chloride particles emitted by the same source underwent heterogeneous transformations into nitrate particles as soon as photochemical production of nitric acid began each day at 7 am.

The impacts of water and NAPL saturation distribution, NAPL-type (i.e., free, residual, or trapped) distribution, and spatial heterogeneity of the permeability field on these mechanisms were evaluated. Two different initial source zone architectures (one with and one without trapped NAPL) were considered and these architectures were used to evaluate seven different SVE scenarios. For all runs, slow diffusion from low permeability zones that gas flow bypassed was a dominant factor for diminished SVE effectiveness at later times. This effect was more significant at high water saturation due to the decrease of gas-phase relative permeability. Transverse dispersion contributed to fast NAPL mass removal from the low permeability layer in both source zone architectures, but longitudinal dispersion did not affect overall mass removal time. Both slow desorption from sediment grains and rate-limited mass transfer from trapped NAPL only marginally affected removal times. However, mass transfer from trapped NAPL did affect mass removal at later time, as well as the NAPL distribution. NAPL flow from low to high permeability zones contributed to faster mass removal from the low permeability layer, and this effect increased when water infiltration was eliminated. These simulations indicate that if trapped NAPL exists in heterogeneous porous media, mass transfer can be improved by delivering gas directly to zones with trapped NAPL and by lowering the water content, which increases the gas relative permeability and changes trapped NAPL to free NAPL.

This paper explores how emphasising proliferation resistance can guide decisions allowing increasing use of nuclear power without challenging international security. It reviews the definition of proliferation resistance and describes how proliferation resistance for a given fuel cycle can be evaluated. It explores how proliferation concerns interact with facility safety and plant operations. Finally, it explores today's thinking in technical measures and R0amp; D programmes that could both decrease the risk of proliferation and ensure the successful renaissance of nuclear power.

AN - 69374098; 18613650 AB - Uranium isotope ratios can provide source information for tracking uranium contamination in a variety of fields, ranging from occupational bioassay to monitoring aftereffects of nuclear accidents. We describe the development of isotope selective laser ionization spectrometry for ultratrace measurement of the minor isotopes (234)U, (235)U, and (236)U with respect to (238)U. The inherent isotopic selectivity of three-step excitation with single-mode continuous wave lasers results in measurement of the minor isotopes at relative abundances below 1 ppm and is not limited by isobaric interferences such as (235)UH(+) during measurement of (236)U. This relative abundance limit is attained without mass spectrometric analysis of the laser-created ions. Uranyl nitrate standards from an international blind comparison were used to test analytical performance for different isotopic compositions and with quantities ranging from 11 ng to 10 microg total uranium. Isotopic ratio determination was demonstrated over a linear dynamic range of 7 orders of magnitude with a few percent relative precision and detection limits below 500 fg for the minor isotopes.

This idealized assumption is just one of many ways in which emissions mitigation actions could play out globally, but not necessarily the most likely. This paper explores the implications of generic policy regimes that lead to stabilization of CO2 concentrations under conditions in which non-Annex I regions delay emissions reductions and in which carbon prices vary across participating regions. The resulting stabilization scenarios are contrasted with the idealized results. Delays in the date by which non-Annex I regions begin to reduce emissions raise the price of carbon in Annex I regions relative to the price of carbon in Annex I in an idealized regime for any given CO2 concentration limit. This effect increases the longer the delay in non-Annex I accession, the lower the non-Annex I carbon prices relative to the Annex I prices, and the more stringent the stabilization level. The effect of delay is very pronounced when CO2 concentrations are stabilized at 450 ppmv, however the effect is much less pronounced at 550 ppmv and above. For long delays in non-Annex I accession, 450 ppmv stabilization levels become infeasible. Adapted from the source document.

We developed a modified thermodynamically based model (TBM) to predict fluid-fluid interfacial areas in porous media for arbitrary drainage-imbibition sequences. The TBM explicitly distinguishes between interfacial areas associated with continuous (free) and isolated (entrapped) nonwetting fluids. The model is restricted to two-fluid systems in which (i) no significant conversion of mechanical work into heat occurs, (ii) the wetting fluid completely wets the porous medium's solid surfaces, and (iii) no changes in interfacial area due to mass transfer between phases occur. We show example calculations for two different drainage-imbibition sequences in two porous media: a highly uniform silica sand and a well-graded silt. The TBM's predictions for interfacial area associated with free nonwetting fluid are identical to those of a previously published geometry-based model (GBM); however, predictions for interfacial area associated with entrapped nonwetting fluid are consistently larger in the TBM than in the GBM. Although a comparison of model predictions with experimental data is currently only possible to a limited extent, good general agreement was found for the TBM. As required model parameters are commonly used as inputs for or tracked during multifluid-flow simulations, the modified TBM may be easily incorporated in numerical codes.

Although previous research has shown that uranium bioremediation is maximized during iron reduction, little is known on how long-term iron/uranium reducing conditions can be maintained. Questions also remain about the stability of uranium and other reduced species after a long-term biostimulation scheme is discontinued and oxidants (i.e., oxygen) re-enter the bioreduced zone. To gain further insights into these processes, four columns, packed with sediment containing iron as Fe-oxides (mainly Al-goethite) and silicate Fe (Fe-containing clays), were operated in the laboratory under field-relevant flow conditions to measure the long-term (>200 day) removal efficiency of uranium from a simulated groundwater during biostimulation with an electron donor (3mM acetate) under low sulfate conditions. The biostimulation experiments were then followed by reoxidation of the reduced sediments with oxygen. During biostimulation, Fe(III) reduction occurred simultaneously with U(VI) reduction. Both Fe-oxides and silicate Fe(III) were partly reduced, and silicate Fe(III) reduction was detected only during the first half of the biostimulation phase while Fe-oxide reduction occurred throughout the whole biostimulation period. Mossbauer measurements indicated that the biogenic Fe(II) precipitate resulting from Fe-oxide reduction was neither siderite nor FeS (sub 0.09) (mackinawite). U(VI) reduction efficiency increased throughout the bioreduction period, while the Fe(III) reduction gradually decreased with time. Effluent Fe(II) concentrations decreased linearly by only 30% over the final 100 days of biostimulation, indicating that bioreducible Fe(III) in the sediment was not exhausted at the termination of the experiment. Even though Fe(III) reduction did not change substantially with time, microorganisms not typically associated with Fe(III) and U(VI) reduction (including methanogens) became a significant fraction of the total microbial population during long-term biostimulation, meaning that most acetate was utilized for biological processes other than Fe(III) and U(VI) reduction. This corresponds with an electron donor/acceptor mass balance showing that the amount of Fe(III), U(VI) and SO (sub 4) (super 2-) reduced accounted for very little (<2%) of the acetate consumed after day 104 of bioreduction. Selected columns were reoxidized after 209 days by discontinuing acetate addition and purging the influent media with a gas containing 20% oxygen. Uranium reoxidation occurred rapidly with a very large uranium spike exiting the column (7-8 times higher than the original influent concentration) which resulted in 61% of the precipitated uranium resolubilized and transported out of the column after 21 days and virtually all of the uranium being removed by day 122. During the first 21 days of reoxidation, the Fe(III) and U(VI) reducing microbial population, as measured by quantitative PCR, remained at pre-oxidation levels (even though the gene transcripts that represent the methanogen population decreased by 99%) indicating that short-term disruptions in biostimulation (equipment failure, etc.) may not negatively affect the uranium reducing microbial population.

The oxygen isotopic compositions of the eighteen presolar silicate (and one oxide) grains found are similar those observed previously in primitive meteorites and interplanetary dust particles, and indicate origins in oxygen-rich red giant or asymptotic giant branch stars, or in supernovae. Four grains with anomalous C isotopic compositions were also detected. (super 12) C/ (super 13) C as well as Si ratios are similar to those of mainstream SiC grains; the N isotopic composition of one grain is also consistent with a mainstream SiC classification. Presolar silicate grains were found in three of the seven AMMs studied, and are heterogeneously distributed within these micrometeorites. Fourteen of the 18 presolar silicate grains and 3 of the 4 C-anomalous grains were found within one AMM, T98G8. Presolar silicate-bearing micrometeorites contain crystalline silicates that give sharp X-ray diffractions and do not contain magnesiowustite, which forms mainly through the decomposition of phyllosilicates and carbonates. The occurrence of this mineral in AMMs without presolar silicates suggests that secondary parent body processes probably determine the presence or absence of presolar silicates in Antarctic micrometeorites.

A psychometric survey was used in an exploratory study of attitudes regarding homeland security systems. Psychometric rating data were obtained from 182 respondents on psychological attributes associated with 12 distinct types of homeland security systems. An inverse relationship was observed for the overall rating attributes of acceptability and risk of civil liberties infringement. Principal components analysis (PCA) yielded a two-factor solution with the rating scale loading pattern suggesting factors of perceived effectiveness and perceived intrusiveness. These factors also showed an inverse relationship. The 12 different homeland security systems showed significantly different scores on the rating scales and PCA factors. Of the 12 systems studied, airport screening, canine detectors, and radiation monitoring at borders were found to be the most acceptable, while email monitoring, data mining, and global positioning satellite (GPS) tracking were found to be least acceptable. Students rated several systems as more effective than professionals, but the overall pattern of results for both types of subjects was similar. The data suggest that risk perception research and the psychometric paradigm are useful approaches for quantifying attitudes regarding homeland security systems and policies and can be used to anticipate potentially significant public acceptance issues.

The coupled ordinary differential equations (ODE) for dynamic gas-particle mass transfer are extremely stiff, and the available numerical techniques are either very expensive or produce oscillatory solutions. These limitations are overcome in MOSAIC with a new dynamic gas-particle partitioning module, which is coupled to an efficient and accurate thermodynamics module. The algorithm includes a new concept of "dynamic pH," a novel formulation for mass transfer to mixed-phase and solid particles, and an adaptive time stepping scheme, which together hold the key to smooth, accurate, and efficient solutions of gas-particle partitioning over the entire relative humidity range. MOSAIC is found to be in excellent agreement with a benchmark version of the model that uses a rigorous solver for integrating the stiff ODEs. The steady-state MOSAIC results for monodisperse aerosol test cases are also in excellent agreement with those obtained with the benchmark equilibrium model AIM. Moreover, the CPU times required for fully dynamic solutions by MOSAIC per size bin per 5 min intervals (typical 3-D model time steps) are similar to those for bulk equilibrium solutions by the computationally efficient but relatively less accurate model ISORROPIA. These results show that MOSAIC is extremely efficient without compromising accuracy, and is therefore highly attractive for use in air quality and regional/global aerosol models.

Agar, widely used in growth of bacteria on solid surfaces, consists primarily of repeating polysaccharide units of 3,6-anhydro-l-galactose (AGal) and galactose (Gal) with sulfated and O-methylated galactoses present as minor constituents. Two variants of the alditol acetate procedure were evaluated for detection of potential agar markers associated with spores. The first method employed a reductive hydrolysis step, to stabilize labile anhydrogalactose, by converting to anhydrogalactitol. The second eliminated the reductive hydrolysis step simplifying the procedure. Anhydrogalactitol, derived from agar, was detected using both derivatization methods followed by gas chromatography-mass spectrometry (GC-MS) analysis. However, challenges with artifactual background (reductive hydrolysis) or marker destruction (hydrolysis) respectively lead to the use of an alternative agar marker. A minor agar component, 6-O-methyl galactose (6-O-M gal), was readily detected in agar-grown but not broth-grown bacteria. Detection was optimized by the use of gas chromatography-tandem mass spectrometry (GC-MS-MS). With appropriate choice of sugar marker and analytical procedure, detection of sugar markers for agar has considerable potential in microbial forensics.

Although E. chaffeensis induces the generation of several cytokines and chemokines by leukocytes, E. chaffeensis lacks lipopolysaccharide and peptidoglycan. Bioinfomatic analysis of the E. chaffeensis genome, however, predicted genes encoding 15 lipoproteins and 3 posttranslational lipoprotein-processing enzymes. The present study showed that by use of multidimensional liquid chromatography followed by tandem mass spectrometry, all predicted lipoproteins as well as lipoprotein-processing enzymes were expressed by E. chaffeensis cultured in the human promyelocytic leukemia cell line HL-60. Consistent with this observation, a signal peptidase II inhibitor, globomycin, was found to inhibit E. chaffeensis infection and lipoprotein processing in HL-60 cell culture. To study in vivo E. chaffeensis lipoprotein expression and host immune responses to E. chaffeensis lipoproteins, 13 E. chaffeensis lipoprotein genes were cloned into a mammalian expression vector. When the DNA constructs were inoculated into naive dogs, or when dogs were infected with E. chaffeensis, the animals developed delayed-type hypersensitivity reactions at cutaneous sites of the DNA construct deposition and serum antibodies to these lipoproteins. This is the first demonstration of lipoprotein expression and elicitation of immune responses by a member of the order RICKETTSIALES: Multiple lipoproteins expressed by E. chaffeensis in vitro and in vivo may play key roles in pathogenesis and immune responses in HME.

Owing to their diverse metabolic capabilities, shewanellae are important for carbon cycling and have considerable potential for the remediation of contaminated environments and use in microbial fuel cells. Systems-level analysis of the model species Shewanella oneidensis MR-1 and other members of this genus has provided new insights into the signal-transduction proteins, regulators, and metabolic and respiratory subsystems that govern the remarkable versatility of the shewanellae.

Coupons of high-purity chemical vapor deposited SiC were exposed to deoxygenated, pressurized water at 573 K and 10 MPa for up to 5400 h. Ceramographic examination of the exposed SiC surfaces revealed both embryonic and large, d > 300 is a subset of m, pits on the surface after initial exposure for 4000 h. The pits were characterized using scanning electron microscopy for structure and chemistry analysis. Pit densities were also determined by standard counting methods. The chemical analysis revealed that the pits are associated with the formation of silica and subsequent loss of Si, which is expected due to several suggested reactions between SiC and water. Subsequent exposure under nominally identical water chemistry conditions for an additional 1400 h removed the pits and the samples exhibited general corrosion with measurable loss of Si from the surface.

A set of sediment-concrete half-cell diffusion experiments was conducted under unsaturated conditions (4% and 7% by weight moisture content) using carbonated and non-carbonated concrete-soil half cells. Results indicate the behavior of Re and I release was comparable within a given half-cell test. Diffusivity in soil is a function of moisture content; a 3% increase in moisture content affords a one to two order of magnitude increase in diffusivity. Release of I and Re was 1-3 orders of magnitude less from non-carbonated, relative to carbonated, concrete monoliths. Inclusion of Fe in non-carbonate monoliths resulted in the lowest concrete diffusivity values for both I and Re. This suggests that in the presence of Fe, I and Re are converted to reduced species, which are less soluble and better retained within the concrete monolith. The release of I and Re was greatest from Fe- bearing, carbonated concrete monoliths, suggesting carbonation negates the effect of Fe on the retention of I and Re within concrete monoliths. This is likely due to enhanced formation of microcracks in the presence of Fe, which provide preferential paths for contaminant migration. Although the release of I and Re were greatest from carbonated concrete monoliths containing Fe, the migration of I and Re within a given half cell is dependent on the moisture content, soil diffusivity, and diffusing species.

Herein, we report quantitative intercomparisons of particle-induced X-ray emission (PIXE) and proton elastic scattering analysis (PESA), performed offline under a vacuum, with analysis by aerosol mass spectrometry (AMS) carried out in real-time during the MCMA-2003 Field Campaign in the Mexico City Metropolitan Area. Good agreement was observed for mass concentrations of PIXE-measured sulfur (assuming it was dominated by SO42-) and AMS-measured sulfate during most of the campaign. PESA-measured hydrogen mass was separated into sulfate H and organic H mass fractions, assuming the only major contributions were (NH4)2SO4 and organic compounds. Comparison of the organic H mass with AMS organic aerosol measurements indicates that about 75% of the mass of these species evaporated under a vacuum. However 25% of the organics does remain under a vacuum, which is only possible with low-vapor-pressure compounds, and which supports the presence of high-molecular-weight or highly oxidized organics consistent with atmospheric aging. Approximately 10% of the chloride detected by AMS was measured by PIXE, possibly in the form of metal-chloride complexes, while the majority of Cl was likely present as more volatile species including NH4Cl. This is the first comparison of PIXE/PESA and AMS and, to our knowledge, also the first report of PESA hydrogen measurements for urban organic aerosols.

AN - 69318030; 18576638 AB - Apurinic/apyrimidinic endonuclease 1 (APE1), a member of the divalent cation-dependent phosphoesterase superfamily of proteins that retain the conserved four-layered alpha/beta-sandwich structural core, is an essential protein that functions as part of base excision repair to remove mutagenic and cytotoxic abasic sites from DNA. Using low-temperature solid-state (25)Mg NMR spectroscopy and various mutants of APE1, we demonstrate that Mg(2+) binds to APE1 and a functional APE1-substrate DNA complex with an overall stoichiometry of one Mg(2+) per mole of APE1 as predicted by the X-ray work of Tainer and co-workers (Mol, C. D.; Kuo, C. F.; Thayer, M. M.; Cunningham, R. P.; Tainer, J. A. Nature 1995, 374 , 381-386). However, the NMR spectra show that the single Mg(2+) site is disordered. We discuss the probable reasons for the disorder at the Mg(2+) binding site. The most likely source of this disorder is arrangement of the protein-ligands about the Mg(2+) (cis and trans isomers). The existence of these isomers reinforces the notion of the plasticity of the metal binding site within APE1.

AN - 69216575; 18558124 AB - Electrochemical sensors have great potential for environmental monitoring of toxic metal ions in waters due to their portability, field-deployability and excellent detection limits. However, electrochemical sensors employing mercury-free approaches typically suffer from binding competition for metal ions and fouling by organic substances and surfactants in natural waters, making sample pretreatments such as wet ashing necessary. In this work, we have developed mercury-free sensors by coating a composite of thiol self-assembled monolayers on mesoporous supports (SH-SAMMS) and Nafion on glassy-carbon electrodes. With the combined benefit of SH-SAMMS as an outstanding metal preconcentrator and Nafion as an antifouling binder, the sensors could detect 0.5 pp b of Pb and 2.5 pp b of Cd in river water, Hanford groundwater, and seawater with a minimal amount of preconcentration time (few minutes) and without any sample pretreatment. The sensor could also detect 2.5 pp b of Cd, Pb, and Cu simultaneously. The electrodes have long service times and excellent single and inter-electrode reproducibility (5% R.S.D. after 8 consecutive measurements). Unlike SAMMS-carbon paste electrodes, the SAMMS-Nafion electrodes were not fouled in samples containing albumin and successfully detected Cd in human urine. Other potentially confounding factors affecting metal detection at SAMMS-Nafion electrodes were studied, including pH effect, transport resistance of metal ions, and detection interference. With the ability to reliably detect low metal concentration ranges without sample pretreatment and fouling, SAMMS-Nafion composite sensors have the potential to become the next-generation metal analyzers for environmental and bio-monitoring of toxic metals.

S. Department of Energy (DOE) facilities. In situ bioremediation is being studied as a potential technology for remediation of uranium and chromium at a number of DOE sites. In situ bioremediation can be implemented by introducing a soluble electron donor (e.g., acetate), thereby stimulating the activity of dissimilatory metal reducing organisms such as Geobacter sulfurreducens that are capable of reducing uranium from the soluble U(VI) valence state to the relatively insoluble U(IV) valence state. Numerical models of groundwater flow and transport combined with biogeochemical transformations are useful tools for supporting interpretation of observations at research sites and potentially for evaluating and designing future field-scale technology deployments. However, conventional reactive transport models often neglect microbial dynamics or simulate microbial effects using static growth yield and a single reaction rate formulation over all simulated conditions, whereas in reality both individual microorganisms and microbial communities are known to dynamically modify their functionality (respiratory pathways and rates) in response to changing environmental conditions. Genome-scale metabolic models based on constraint-based flux analyses (in silico models) have been demonstrated to correctly predict the transient metabolism of some well studied microorganisms and identify growth rates and substrate uptake rates under variable growth conditions. These rates can be used to replace conventional microbially-mediated reaction rate formulations (such as Monod kinetics) in a reactive transport model using the simulated local geochemical conditions as constraints. A framework integrating the genome-scale metabolic model and transport process has been developed and numerical simulations of bacterial metal reduction in subsurface sediments have been performed. This model incorporates the flow of groundwater in a heterogeneous system and the dynamics of growth and respiration of G. sulfurreducens with acetate as the electron donor and iron and uranium as the electron acceptors. We present simulations of metal reduction under conditions of excess ammonium and conditions of ammonium limitation (requiring microbial nitrogen fixation). We also present results of preliminary model application to field observations from in situ uranium bioreduction experiments conducted at the Old Rifle uranium mill tailings site in Colorado.

AN - 69373716; 18672715 AB - Certain widely used wind rose programs and air dispersion models use an overly simple data-transfer algorithm that induces a directional bias in their output products. The purpose of this paper is to provide a revised algorithm that corrects the directional bias that occurs from the aliasing that occurs when the sector widths used to report wind direction data are on the same order of magnitude, but not equal, to the sector widths used in the wind direction summaries. The directional bias issue arises when output products in 16 direction sectors (22.5 degrees each) are produced from wind direction data reported in terms of 36 sectors (10 degrees each). The result directional bias affects the results of simulations of air and surface concentrations using widely applied air dispersion models. Datasets or models with the directional bias discussed here give consistent positive biases (approximately 30%) for cardinal direction sectors (north, south, east, and west) and consistent negative biases for all of the other sectors (around -10%). Data summary and air dispersion programs providing outputs in direction sectors that do not match the observational sectors need to be checked for this bias. A revised data-transfer algorithm is provided that corrects the directional bias that can occur in transferring wind direction data between different sector widths.

In terms of natural resource management, this will typically integrate monitoring, databases, simulation modeling, decision theory, and expert judgment to evaluate management alternatives and adapt them as necessary to continually improve the natural resource condition as defined by stakeholders. Natural resource management scenarios can often be expressed, viewed, and understood as a geospatial and temporal problem. The integration of Geographic Information System (GIS) technologies and physically-based models provide an effective state-of-the-art solution for deriving, understanding, and applying AM scenarios for land use and remediation. A recently developed GIS-based adaptive management decision support system is presented for the U.S. Department of Defense Yakima Training Center near Yakima, Washington.

Two-dimensional IR Correlation Spectroscopy was used to identify correlations between different sets of discrete surface OH stretches and a Multivariate Curve Resolution analysis was used to resolve the predominant spectral components. Two dominant groups of hydroxyls were identified on the basis of their differences in proton affinity. Group I hydroxyls appear as two 3698/3541 and 3660/3490 cm (super -1) band pairs. Group II hydroxyls are manifested through the 3648 and 3578 cm (super -1) bands at greater levels of surface proton loading. There is consequently no correlation between O-H stretching frequencies and proton affinity. Groups I and II were assigned to mostly singly- (-OH) and doubly- (mu -OH) coordinated hydroxyls, respectively. Stretches arising from triply-coordinated (mu (sub 3) -OH) are proposed to be embedded within the dominant O-H band of bulk goethite. The possibility that these sites contribute to Group I and II hydroxyls should, however, not be entirely dismissed without further investigations. A reexamination of Temperature Programmed Desorption (TPD)-FTIR data of one goethite sample evaporated from alkaline conditions [Boily, J.-F., Szanyi, J., Felmy, A. R. (2006) A combined FTIR and TPD study on the bulk and surface dehydroxylation and decarbonation of synthetic goethite. Geochim. Cosmochim. Acta 70, 3613-3624] provided further constraints to this band assignment by providing clues to the network of surface hydrogen bonds. Important cooperative effects between hydrogen-bonded surface hydroxyls are suggested to play a crucial role on the variations of the position and intensity of discrete O-H stretching bands as a function of protonation level and temperature.

In the experimental investigation, solutions containing Na2CO3 and CaCl2 were each injected in different halves of a quasi two-dimensional flow cell filled with quartz sand. As a result of the in situ mixing between the two solutions, a narrow calcite precipitate layer (less than 5 mm wide) of more or less uniform width was formed between the individual solutions. Pore-scale simulations were conducted to help understand the mechanism of precipitation layer formation. The effect of the Peclet number, , and the Damkohler number, , on mixing induced precipitation was also investigated. Pore-scale simulations revealed the presence of large pore-scale concentration gradients. This, and the presence of features, such as the precipitation layer, with characteristic lengths on the order of the average sand grain diameter, indicate the absence of a clear scale separation required for the strict derivation of Darcy-scale advection-dispersion equations. Nevertheless, we found that an adaptive high-resolution model based on advection-dispersion equations with grid sizes in the mixing zone smaller than the size of the sand grains can qualitatively reproduce the essential features of the experiment. As an alternative to computationally expensive high-resolution simulations, we proposed new forms for the homogeneous and heterogeneous reaction terms in Darcy-scale advection dispersion equations. These terms involve transport and mixing indices that account for highly nonuniform pore-scale concentration distributions and highly localized reactions. The proposed model accurately estimates the changes in solute concentrations due to homogenous and heterogeneous reactions during precipitation of minerals, observed in the pore-scale simulations, while conventional low-resolution advective-dispersion equations produced erroneous results.

Confocal microscopy analysis of the extracellular matrix material contributing to the stability of the aggregate structures revealed the presence of extracellular DNA, protein and glycoconjugates. Upon onset of O2-limited growth (dissolved O2 below detection) however, the Ca2+-supplemented chemostat cultures of strain MR-1 rapidly disaggregated and grew as motile dispersed cells. Global transcriptome analysis comparing aerobic aggregated to O2-limited unaggregated cells identified genes encoding cell-to-cell and cell-to-surface adhesion factors whose transcription increased upon exposure to increased O2 concentrations. The aerobic aggregated cells also revealed increased expression of putative anaerobic electron transfer and homologues of metal reduction genes, including mtrD (SO1782), mtrE (SO1781) and mtrF (SO1780). Our data indicate that mechanisms involved in autoaggregation of MR-1 are dependent on the function of pilD gene which encodes a putative prepilin peptidase. Mutants of S.oneidensis strain MR-1 deficient in PilD and associated pathways, including type IV and Msh pili biogenesis, displayed a moderate increase in sensitivity to H2O2. Taken together, our evidence indicates that aggregate formation in S.oneidensis MR-1 may serve as an alternative or an addition to biochemical detoxification to reduce the oxidative stress associated with production of reactive oxygen species during aerobic metabolism while facilitating the development of hypoxic conditions within the aggregate interior.

Here we have compared the transcriptome and proteome profiles of the wild-type (WT) and mutant PrrA2 cells grown anaerobically in the dark with dimethyl sulfoxide as an electron acceptor. Approximately 25% of the genes present in the PrrA2 genome are regulated by PrrA at the transcriptional level, either directly or indirectly, by twofold or more relative to the WT. The genes affected are widespread throughout all COG (cluster of orthologous group) functional categories, with previously unsuspected "metabolic" genes affected in PrrA2 cells. PrrA was found to act as both an activator and a repressor of transcription, with more genes being repressed in the presence of PrrA (9:5 ratio). An analysis of the genes encoding the 1,536 peptides detected through our chromatographic study, which corresponds to 36% coverage of the genome, revealed that approximately 20% of the genes encoding these proteins were positively regulated, whereas approximately 32% were negatively regulated by PrrA, which is in excellent agreement with the percentages obtained for the whole-genome transcriptome profile. In addition, comparison of the transcriptome and proteome mean parameter values for WT and PrrA2 cells showed good qualitative agreement, indicating that transcript regulation paralleled the corresponding protein abundance, although not one for one. The microarray analysis was validated by direct mRNA measurement of randomly selected genes that were both positively and negatively regulated. lacZ transcriptional and kan translational fusions enabled us to map putative PrrA binding sites and revealed potential gene targets for indirect regulation by PrrA.

AN - 69205900; 18469584 AB - After the events of 11 September 2001, the possibility of a dirty bomb being detonated within the United States seems more realistic. Development of tools for use in response to a dirty bomb detonation has become a topic of both discussion and research. While it has been reported that the health risk to the public from such an event would likely be small, it is thought that the psychological impact could be considerable. One response option that has been considered is adapting sprayable solutions for the purpose of fixing contamination in place, thereby limiting the spread of contamination by wind and rain and facilitating subsequent cleanup. This work evaluated two commercially available particle fixatives (IsoFIX-HT and IsoFIX-RC) for their effectiveness in preventing dispersal of simulated contamination. Nonradioactive cesium chloride and cobalt oxide particles were selected as the simulated contamination and applied to the surface of three outdoor test plots. Two test plots were treated with fixatives; the third plot provided a control. Samples were collected over 95 days to observe changes in tracer concentration on the surface of the test plots. One fixative (IsoFIX-RC) effectively held the tracer in place with no net loss of tracer, while the other fixative (IsoFIX-HT) had no impact on the loss of tracer relative to the control. Under the conditions tested, IsoFIX-RC appears capable of fixing surface contamination in place for at least several months.

The chemically complex borosilicate glasses are representative of prospective hosts for radioactive waste disposal and are characterized by relatively high molar Si/(Si + Al) and Na/(Al + B) ratios (>0.7 and >1.0, respectively). Analysis by X-ray absorption spectroscopy (XAS) indicates that the fraction of (super iv) B to (super iii) B (N (sub 4) ) varies from 0.66 to 0.70. Despite large differences in bulk chemistry, values of delta (super 29) Si peak shift determined by MAS-NMR varies only by about 7ppm (delta (super 29) Si = -94 to -87 ppm), indicating small differences in polymerization state for the glasses. Forward rates of reaction measured in dynamic experiments converge (average log (sub 10) rate [40 degrees C, pH 9] = -1.87 + or - 0.79 [g/(m (super 2) d)]) at high values of flow-rate (q) to sample surface area (S). Dissolution rates are independent of total Free Energy of Hydration (FEH) and this model appears to overestimate the impact of excess Na on chemical durability. For borosilicate glass compositions in which molar Na > Al + B, further addition of Na appears to stabilize the glass structure with respect to hydrolysis and dissolution. Compared to other borosilicate and aluminosilicate glasses, the glass specimens from this study dissolve at nearly the same rate (0- nearly equal 56x) as the more polymerized glasses, such as vitreous reedmergnerite (NaBSi (sub 3) O (sub 8) ), albite, and silica. Dissolution of glass follows the order: boroaluminosilicate glass > vitreous reedmergnerite > vitreous albite > silica glass, which is roughly the same order of increasingly negative (super 29) Si chemical shifts. The chemical shift of (super 29) Si is a measure of the extent of bond overlap between Si and O and correlates with the forward rate of reaction. Thus, dissolution appears to be rate-limited by rupture of the Si-O bond, which is consistent with the tenants of Transition State Theory (TST). Therefore, dissolution at far from equilibrium conditions is dependent upon the speed of the rate-controlling elementary reaction and not on the sum of the free energies of hydration of the constituents of boroaluminosilicate glass.

Results from X-ray absorption near-edge structure (XANES) spectroscopy revealed that gamma -sterilized sediments were actually better sorbents of U(VI), despite the absence of any measurable biological activity. These results indicate that gamma -irradiation induced significant physico-chemical changes in the sediment which is contrary to numerous other studies identifying gamma -sterilization as an effective and minimally invasive technique. To identify the extent and method of alteration of the soil as a result of gamma -sterilization, untreated soil samples, physically separated size fractions, and chemically extracted fractions of the soil were analyzed pre- and post-sterilization. The effects of sterilization on mineralogy, pH, natural organic matter (NOM), cation exchange capacity (CEC), and iron oxidation state were determined. Results indicated that major mineralogy of the clay and whole sediment samples was unchanged. Sediment pH decreased only slightly with gamma -irradiation; however, irradiation produced a significant decrease in CEC of the untreated sediments and affected both the organic and inorganic fractions. Mossbauer spectra of non-sterile and gamma -sterilized sediments measured more reduced iron present in gamma -sterilized sediments compared to non-sterile samples. Our results suggest that sterilization by gamma -irradiation induced iron reduction that may have increased the sorption and/or reduction of U(VI) onto these sediments. However, Mossbauer and batch sorption data are somewhat contradictory, the former indicates that the iron oxide or iron hydroxide minerals are more significantly reduced while the later indicates that reduced clay minerals account for greater sorption of U(VI).

This paper reviews the research undertaken developing this new option for biomass gasification. This review does not cover wet oxidation or near-atmospheric-pressure steam-gasification of biomass. Laboratory research on hydrothermal gasification of biomass focusing on the use of catalysts is reviewed here, and a companion review focuses on non-catalytic processing. Research includes liquid-phase, subcritical processing as well as supercritical water processing. The use of heterogeneous catalysts in such a system allows effective operation at lower temperatures, and the issues around the use of catalysts are presented. This review attempts to show the potential of this new processing concept by comparing the various options under development and the results of the research.

The work of Dr Terry Beveridge and colleagues provided some of the first insights into metal-microbe and mineral-microbe interactions and established a foundation for subsequent detailed investigations of interactions between microorganisms and minerals. Beveridge also envisioned that interdisciplinary approaches and teams would be required to explain how individual microbial cells interact with their immediate environment at nano- or microscopic scales and that through such approaches and using emerging technologies that the details of such interactions would be revealed at the molecular level. With this vision as incentive and inspiration, a multidisciplinary, collaborative team-based investigation was initiated to probe the process of electron transfer (ET) at the microbe-mineral interface. The grand challenge to this team was to address the hypothesis that multiheme c-type cytochromes of dissimilatory metal-reducing bacteria localized to the cell exterior function as the terminal reductases in ET to Fe(III) and Mn(IV) oxides. This question has been the subject of extensive investigation for years, yet the answer has remained elusive. The team involves an integrated group of experimental and computational capabilities at US Department of Energy's Environmental Molecular Sciences Laboratory, a national scientific user facility, as the collaborative focal point. The approach involves a combination of in vitro and in vivo biologic and biogeochemical experiments and computational analyses that, when integrated, provide a conceptual model of the ET process. The resulting conceptual model will be evaluated by integrating and comparing various experimental, i.e. in vitro and in vivo ET kinetics, and theoretical results. Collectively, the grand challenge will provide a detailed view of how organisms engage with mineral surfaces to exchange energy and electron density as required for life function.

High-resolution 1H NMR metabolic profiling on intact excised lungs was performed using slow magic angle sample spinning (slow-MAS) 1H PASS (phase-altered spinning sidebands) at a sample spinning rate of 80 Hz. Metabolic profiling on BALF was completed using fast magic angle spinning at 2 kHz. Major findings are that the relative concentrations of choline, phosphocholine (PC), and glycerophosphocholine (GPC) were statistically significantly increased in silica-exposed mice compared to sham controls, indicating an altered membrane choline phospholipids metabolism (MCPM). The relative concentrations of glycogen/glucose, lactate, and creatine were also statistically significantly increased in mice exposed to silica dust, suggesting that cellular energy pathways were affected by silica dust. Elevated levels of glycine, lysine, glutamate, proline, and 4-hydroxyproline were also increased in exposed mice, suggesting the activation of a collagen pathway. Furthermore, metabolic profiles in mice exposed to silica dust were found to be spatially heterogeneous, consistent with regional inflammation revealed by in vivo magnetic resonance imaging (MRI).

Culture medium, presence of agar, culturing temperature, and drying method are just some of the broad spectrum of characteristics an investigator might like to infer. The effects of many of these factors on microorganisms are not well understood, but the complex way in which microbes interact with their environments suggests that numerous analytical techniques measuring different properties will eventually be needed for complete characterization. In this work, we present a Bayesian statistical framework for integrating disparate analytical measurements. We illustrate its application to the problem of characterizing the culture medium of Bacillus spores using three different mass spectral techniques. The results of our study suggest that integrating data in this way significantly improves the accuracy and robustness of the analyses.

AN - 69194790; 18378659 AB - Shewanella oneidensis MR-1 is the first of 22 different Shewanella spp. whose genomes have been or are being sequenced and thus serves as the model organism for studying the functional repertoire of the Shewanella genus. The original MR-1 genome annotation revealed a large number of transposase genes and pseudogenes, indicating that many of the genome's functions may be decaying. Comparative analyses of the sequenced Shewanella strains suggest that 209 genes in MR-1 have in-frame stop codons, frameshifts, or interruptions and/or are truncated and that 65 of the original pseudogene predictions were erroneous. Among the decaying functions are that of one of three chemotaxis clusters, type I pilus production, starch utilization, and nitrite respiration. Many of the mutations could be attributed to members of 41 different types of insertion sequence (IS) elements and three types of miniature inverted-repeat transposable elements identified here for the first time. The high copy numbers of individual mobile elements (up to 71) are expected to promote large-scale genome recombination events, as evidenced by the displacement of the algA promoter. The ability of MR-1 to acquire foreign genes via reactions catalyzed by both the integron integrase and the ISSod25-encoded integrases is suggested by the presence of attC sites and genes whose sequences are characteristic of other species downstream of each site. This large number of mobile elements and multiple potential sites for integrase-mediated acquisition of foreign DNA indicate that the MR-1 genome is exceptionally dynamic, with many functions and regulatory control points in the process of decay or reinvention.

Three-dimensional simulations were executed using layered and heterogeneous distributions of soil properties to investigate the vertical and lateral distribution of CCl (sub 4) beneath its release point (216-Z-9 trench) and the effects of soil vapor extraction. The complexity of the modeled physical processes--namely, the nonlinearities associated with multifluid subsurface flow, including phase transitions and hysteresis in the relative permeability-saturation-capillary pressure functions--limits the grid resolution when executed using single-processor computers. To achieve higher grid resolutions and acceptable detail in the simulation results for subsurface distribution and remediation of CCl (sub 4) , execution on multiple processors was required. We have developed a scalable implementation of a multifluid subsurface flow and transport simulator, STOMP, with capabilities for volatile organic compounds. Developing scientific software for execution on parallel computers has unique challenges. The guiding objectives for developing this scalable code were to keep the source coding readable and modifiable by subsurface scientists, to allow for both sequential and scalable processing, and to depend on domain scientists for code parallelization and scalable linear system solvers.

US Government-sponsored building energy efficiency research and implementation programs are focused on reducing energy consumption in US residential and commercial buildings and reducing these carbon (C) emissions. Although not specifically intended for adaptation to a warmer climate and less effective than under today's cooler climate, these programs also could help reduce energy demand in a future warmer world. Warming scenarios projected by the United Nations Intergovernmental Panel on Climate Change (IPCC) in 2001 imply net overall decreases in both site energy and primary energy consumption in US residential and commercial buildings, largely because of the reduced need for heating. However, there would be as much as a 25% increase in building space cooling demand and a significant part of the increase could be offset by energy-efficiency improvements in buildings. Overall, in the US, buildings-related energy efficiency programs would reduce site energy consumption in buildings in the US by more than 2 EJ in 2020 and primary energy by more than 3.5 EJ, more than enough to offset the projected growth in cooling energy consumption due to climate change and growth in the US building stock. The savings would have an estimated annual net value at 2005 energy prices of between $45.0 and $47.3 billion to consumers.

Conventional reactive transport models often ignore the microbialeffects or simulate the microbial effects with static growth yield and constant reaction rate parameters oversimulated conditions, while in reality microorganisms can dynamically modify their functionality in response tochanging environmental conditions. Constraint-based in silico models, using genomic data and multiple-pathway reaction networks, have been shown to be able to simulate transient metabolism of some well studiedmicroorganisms and identify growth rate and substrate uptake rates under different growth conditions. Theserates can be identified and used to replace important microbially-mediated reaction rates in a reactive transportmodel using local geochemical conditions as constraints. We present the development of a novel simulationcode that integrates a constraint-based in silico model with a state-of-the-art flow and reactive transport modeland show preliminary results from the integrated model.

AN - 70778729; 18505017 AB - Certain saliva enzymes may be useful biomarkers for detecting exposures to organophosphate pesticides and chemical nerve agents. In this regard, saliva biomonitoring offers a simple and noninvasive approach for rapidly evaluating those exposures in real time. An electrochemical sensor coupled with a microflow injection system was developed for a simple, rapid, and sensitive characterization of cholinesterase (ChE) enzyme activities in rat saliva. The electrochemical sensor is based on a carbon nanotube (CNT)-modified screen-printed carbon electrode (SPE), which is integrated into a flow cell. Because of the excellent electrocatalytic activity of the CNTs, the sensor can detect electroactive species that are produced from enzymatic reactions with extremely high sensitivity and at low potentials. The electrochemical properties of acetylcholinesterase (AChE) enzymatic products were studied using a CNT-modified SPE, and the operation parameters such as the applied potential and substrate concentration were optimized to achieve the best performance. The AChE enzyme activity was further investigated using the CNT-based electrochemical sensor with commercially available purified AChE and ChE in saliva obtained from nave rats. It is found that the calibration curve is linear over a wide range of AChE concentrations from 5 pM to 0.5 nM, and the sensor is very sensitive with the detection limit down to 2 pM. The dynamics of the ChE enzyme activity in saliva with organophosphate pesticides was further studied using this sensor. The results showthatthe senor can be used to characterize salivary enzyme activity and to detect the exposure to organophosphate compounds. This new CNT-based electrochemical sensor thus provides a sensitive and quantitative tool for noninvasive biomonitoring of the exposure to organophosphate pesticides and nerve agents.

Specifically, we observed that a chemically induced surface potential gradient across hematite (alpha -Fe (sub 2) O (sub 3) ) crystals is sufficiently high and the bulk electrical resistivity sufficiently low that dissolution of edge surfaces is linked to simultaneous growth of the crystallographically distinct (001) basal plane. The apparent importance of bulk crystal conduction is likely to be generalizable to a host of naturally abundant semiconducting minerals playing varied key roles in soils, sediments, and the atmosphere.

These factors were varied in sediment suspension experiments to identify geochemical processes that affect migration of Sr (super 2+) and Cs (super +) introduced to the subsurface by caustic high level radioactive waste (HLRW). Three glacio-fluvial and lacustrine sediments from the Hanford Site (WA, USA) were subjected to hyperalkaline (pH>13), Na-Al-NO (sub 3) -OH solution conditions within a gradient field of (i) sorptive concentration (10 (super -5) -10 (super -3) m) and (ii) reaction time (0-365 d). Strontium uptake (q (sub Sr) ) exceeded that of cesium at nearly all reaction times. Sorbent affinity for both Cs (super +) and Sr (super 2+) increased with clay plus silt content at early times, but a prolonged slow uptake process was observed over the course of sediment weathering that erased the texture effect for Sr (super 2+) ; all sediments showed similar mass normalized uptake after several months of reaction time. Strontium became progressively recalcitrant to desorption after 92d, with accumulation and aging of neoformed aluminosilicates. Formation of Cs (super +) and Sr (super 2+) -containing cancrinite and sodalite was observed after 183d by SEM and synchrotron mu -XRF and mu -XRD. EXAFS data for q (sub Sr) nearly equal 40 mmol kg (super -1) showed incorporation of Sr (super 2+) into both feldspathoid and SrCO (sub 3) (s) coordination environments after one year. Adsorption was predominant at early times and low sorbate amount, whereas precipitation, controlled largely by sediment Si release, became increasingly important at longer times and higher sorbate amount. Kinetics of contaminant desorption at pH 8 from one year-weathered sediments showed significant dependence on background cation (Ca (super 2+) versus K (super +) ) composition. Results of this study indicate that co-precipitation and ion exchange in neoformed aluminosilicates may be an important mechanism controlling Sr (super 2+) and Cs (super +) mobility in siliceous sediments impacted by hyperalkaline HLRW.

Fine scale pressures and velocities are computed for a 35.5 min period over a two-dimensional beach profile measured during the 1990 Delilah field experiment. The model is driven by observed wave spectra obtained in 8 m water depth, and results compared with a cross-shore array of pressure sensors and current meters extending from near the shoreline to beyond the surf zone and the spatial distribution of wave breaking patterns obtained from video data. In the calculations, wave breaking is a natural consequence of the fluid dynamics and does not require the use of empirical formulations or breaking criteria. Good agreement between modeled and observed wave height transformation, mean cross-shore flow, and wave breaking variability suggests that the model can be used as a numerical laboratory to study the wave breaking and dissipation process in detail, and perhaps lead to improved parametrizations for more computationally efficient numerical models.

As a consequence the density of Mo-41Re initially decreases and then increases thereafter. Beginning as a single-phase solid solution of Re and Mo, irradiation of Mo-41 wt% Re over a range of temperatures (470-730 DGC) to 28-96 dpa produces a high density of thin platelets of a hexagonal close-packed (hcp) phase identified as a solid solution of Re, Os and possibly a small amount of Mo. These hcp precipitates are thought to form in the alloy matrix as a consequence of strong radiation-induced segregation to Frank loops. Grain boundaries also segregate Re to form the hcp phase, but the precipitates are much bigger and more equiaxed in shape. Although not formed at lower dose, continued irradiation at 730 DGC leads to the co-formation of late-forming chi-phase, an equilibrium phase that then competes with the preexisting hcp phase for rhenium.

Measures of biomass, community structure, and genetic diversity were used to investigate impacts of uranium (U) exposure on periphyton. Laboratory exposures of periphyton in river water amended with super(238)U were performed for 5 days, followed by 2 days of U depuration in unamended river water. Productivity as measured by biomass was not affected by concentrations up to 100 mu g super(238)U L super(-1). Phospholipid fatty acid (PLFA) profiles and denaturing gradient gel electrophoresis (DGGE) banding patterns revealed no changes in community or genetic structure related to U exposure. We suggest that the periphyton community as a whole was not significantly impacted by exposures of super(238)U up to a concentration of 100 mu g L super(-1). These findings have significance for the assessment and prediction of U impacts on aquatic ecosystems.

Results suggest that the availability of dissolved oxygen determines the dominant biodegradation pathway; ether cleavage and the formation of NP is favored by oxic conditions, while alkyl chain oxidation and the formation of CAP1ECs is favored under microxic conditions. In the Mesa microcosms, para-NP1EC was transformed to para-nonylphenol (NP) before being rapidly transformed to nonyl alcohols via ipso-hydroxylation. In the Coyote Creek microcosms, large quantities of CAP1ECs were observed. Initially, CA8P1ECs were the dominant metabolites, but as biodegradation continued, CA6P1ECs became the dominant metabolites. Compared to the CA8P1ECs, the number of CA6P1ECs peaks observed was small (<6) even though their concentrations were high. Several novel metabolites, tentatively identified as 3-alkylchroman-4-carboxylic acids (with alkyl groups ranging from C2 to C5), were formed in the Coyote Creek microcosms. These metabolites are presumably formed from ortho-CAP1ECs by intramolecular ring closure.

AN - 70402999; 18313996 AB - Bronchoalveolar lavage fluid (BALF) contains proteins derived from various pulmonary cell types, secretions and blood. As the characterization of the BALF proteome will be instrumental in establishing potential biomarkers of pathophysiology in the lungs, the objective of this study was to contribute to the comprehensive collection of Mus musculus BALF proteins using high resolution and highly sensitive micro-capillary liquid chromatography (microLC) combined with state-of-the-art high resolution mass spectrometry (MS). BALF was collected from ICR and C57BL/6 male mice exposed to nose-only inhalation to either air or cigarette smoke. The tandem mass spectra were analyzed by SEQUEST for peptide identifications with the subsequent application of accurate mass and time tags resulting in the identification of 1797 peptides with high confidence by high resolution MS. These peptides covered 959 individual proteins constituting the largest collection of BALF proteins to date. High throughput monitoring profiles of this extensive collection of BALF proteins will facilitate the discovery and validation of biomarkers that would elucidate pathogenic or adaptive responses of the lungs upon toxic insults.

AN - 70343512; 18299749 AB - Urine is universally recognized as one of the best non-invasive matrices for biomonitoring exposure to a broad range of xenobiotics, including toxic metals. Detection of metal ions in urine has been problematic due to the protein competition and electrode fouling. For direct, simple, and field-deployable monitoring of urinary Pb, electrochemical sensors employing superparamagnetic iron oxide (Fe3O4) nanoparticles with a surface functionalization of dimercaptosuccinic acid (DMSA) has been developed. The metal detection involves rapid collection of dispersed metal-bound nanoparticles from a sample solution at a magnetic or electromagnetic electrode, followed by the stripping voltammetry of the metal in acidic medium. The sensors were evaluated as a function of solution pH, the binding affinity of Pb to DMSA-Fe3O4, the ratio of nanoparticles per sample volume, preconcentration time, and Pb concentrations. The effect of binding competitions between the DMSA-Fe3O4 and urine constituents for Pb on the sensor responses was studied. After 90 s of preconcentration in samples containing 25 vol.% of rat urine and 0.1 g L(-1) of DMSA-Fe3O4, the sensor could detect background level of Pb (0.5 ppb) and yielded linear responses from 0 to 50 ppb of Pb, excellent reproducibility (%RSD of 5.3 for seven measurements of 30 ppb Pb), and Pb concentrations comparable to those measured by ICP-MS. The sensor could also simultaneously detect background levels (<1 ppb) of Cd, Pb, Cu, and Ag in river and seawater.

The sediments were collected from an area adjacent to and below tank BX-102 that was contaminated as a result of a radioactive tank waste overfill event. The primary reservoir for U(VI) in the sediments are micrometer-size precipitates composed of nanocrystallite aggregates of a Na-U-Silicate phase, most likely Na-boltwoodite, that nucleated and grew within microfractures of the plagioclase component of sand-sized granitic clasts. Two sediment samples, with different U(VI) concentrations and intraparticle mass transfer properties, were leached with advective flows of three different solutions. The influent solutions were all calcite-saturated and in equilibrium with atmospheric CO2. One solution was prepared from DI water, the second was a synthetic groundwater (SGW) with elevated Na that mimicked groundwater at the Hanford site, and the third was the same SGW but with both elevated Na and Si. The latter two solutions were employed, in part, to test the effect of saturation state on U(VI) release. For both sediments, and all three electrolytes, there was an initial rapid release of U(VI) to the advecting solution followed by slower near steady-state release. U(VI)aq concentrations increased during subsequent stop-flow events. The electrolytes with elevated Na and Si depressed U(VL)aq concentrations in effluent solutions. Effluent U(VI)aq concentrations for both sediments and all three electrolytes were simulated reasonably well by a three domain model (the advecting fluid, fractures, and matrix) that coupled U(VI) dissolution, intraparticle U(VI)aq diffusion, and interparticle advection, where diffusion and dissolution properties were parameterized in a previous batch study.

We examined the relationship between hyporheic exchange and temperature along a 24-km reach of the lower Clackamas River, a large gravel-bed river in northwestern Oregon (median discharge = 75.7 m (super 3) /s; minimum mean monthly discharge = 22.7 m (super 3) /s in August 2006). With a simple mixing model, we estimated how much hyporheic exchange cools the river during hot summer months. Hyporheic exchange was primarily identified by temperature anomalies, which are patches of water that demonstrate at least a 1 degrees C temperature difference from the main channel. Forty hyporheic temperature anomalies were identified through field investigations and thermal-infrared-radiometry (TIR) in summer 2006. The location of anomalies was associated with specific geomorphic features, primarily bar channels and bar heads that act as preferential pathways for hyporheic flow. Detailed field characterization and groundwater modelling on three Clackamas gravel bars indicate residence times of hyporheic water can vary from hours to weeks and months. This was largely determined by hydraulic conductivity, which is affected by how recently the gravel bar formed or was reworked. Upscaling of modelled discharges and hydrologic parameters from these bars to other anomalies on the Clackamas network shows that hyporheic discharge from anomalies comprises a small fraction (<<1%) of mainstem discharge, resulting in small river-cooling effects (0.012 degrees C). However, the presence of cooler patches of water within rivers can act as thermal refugia for fish and other aquatic organisms, making the creation or enhancement of hyporheic exchange an attractive method in restoring the thermal regime of rivers.

The objective was to confirm the presence and determine the origin and stability of 2:1 and interlayered 2:1 phyllosilicates in well-drained Andosols. This was and still is a debated topic in the literature. Total elemental and selective dissolution, as well as microscopic and X-ray diffraction analyses, were performed on the soil samples collected from this site. These analyses confirmed that andic properties were present in the soil samples. The allophane content determined by selective dissolution was 3-4% in the A horizons, and increased to 12-18% in the deeper subsoil horizons. In addition, the clay fraction contained dioctahedral smectite, hydroxy-Al-interlayered 2:1 minerals (HIS), Al-chlorite, kaolinite, pyrophyllite, mica, cristobalite and some gibbsite. The silt and sand fractions were rich in plagioclase and pyroxene. The 2:1 minerals (smectite and pyrophyllite), as well as chlorite and kaolinite were of hydrothermal origin and were incorporated in the tephra during volcanic eruption. Besides desilication during dissolution of unstable minerals, Al interlayering of 2:1 layer silicates was most likely the most prominent pedogenic process. Although hydroxy-Al polymeric interlayers would normally stabilize the 2:1 clay phases, the strong weakening, and even disappearance of the characteristic XRD peaks, indicated instability of these minerals in the upper A horizons due to the perudic and intensive leaching conditions.

Electron density profiles were computed from the molecular dynamics trajectories and compared with those derived experimentally from high-resolution X-ray reflectivity measurements by Fenter and co-workers [Fenter, P., Cheng, L., Park, C., Zhang, H. and Sturchio, N. C. (2003a) Structure of the orthoclase (001)- and (010)-water interfaces by high-resolution X-ray reflectivity. Geochim. Cosmochim. Acta 67, 4267-4275]. For each surface, three scenarios were considered whereby the interfacial species is potassium, water, or a hydronium ion. Excellent agreement was obtained for the (001) surface when potassium is the predominant interfacial species; however, some discrepancies in the position of the interfacial peaks were obtained for the (010) surface. The two surfaces showed similarities in the extent of water ordering at the interface, the activation energies for water and potassium desorption, and the adsorption localization of interfacial species. However, there are also important differences between the two surfaces in the coordination of a given adsorbed species, adsorption site densities, and the propensity for water molecules in surface cavities and those in the first hydration layer to coordinate to surface bridging oxygen atoms. These differences may have implications for the extent of dissolution in the low-pH regime since hydrolysis of Si(Al)_O_Si(Al) bonds is a major dissolution mechanism.

The heterogeneous reduction of Tc(VII) by Fe(II) adsorbed to the Fe(III) oxides increased with increasing pH and was coincident with a second event of Fe2+(aq) adsorption. The reaction was almost instantaneous above pH 7. In contrast, the reduction rates of Tc(VII) by DCB-reduced phyllosilicates were not sensitive to pH or to added Fe2+(aq) that adsorbed to the clay. The reduction kinetics were orders of magnitude slower than observed for the Fe(III) oxides, and appeared to be controlled by structural Fe(II). The following affinity series for heterogeneous Tc(VII) reduction by Fe(II) was suggested by the experimental results: aqueous Fe(II) approximately adsorbed Fe(II) in phyllosilicates [ion-exchangeable and some edge-complexed Fe(II)]< structural Fe(II) in phyllosilicates< Fe(II) adsorbed on Fe(III) oxides. Tc-EXAFS spectroscopy revealed that the reduction products were virtually identical on hematite and goethite that were comprised primarily of sorbed octahedral TcO (sub 2) monomers and dimers with significant Fe(III) in the second coordination shell. The nature of heterogeneous Fe(III) resulting from the redox reaction was ambiguous as probed by Tc-EXAFS spectroscopy, although Mossbauer spectroscopy applied to an experiment with (super 56) Fe-goethite with adsorbed (super 57) Fe(II) implied that redox product Fe(III) was goethite-like. The Tc(IV) reduction product formed on the DCB-reduced phyllosilicates was different from the Fe(III) oxides, and was more similar to Tc(IV) oxyhydroxide in its second coordination shell. The heterogeneous reduction of Tc(VII) to less soluble forms by Fe(III) oxide-adsorbed Fe(II) and structural Fe(II) in phyllosilicates may be an important geochemical process that will proceed at very different rates and that will yield different surface species depending on subsurface pH and mineralogy.

Black C was collected from 11 historical charcoal blast furnace sites with a geographic distribution from Quebec, Canada, to Georgia, USA, and compared to BC that was newly produced (new BC) using rebuilt historical kilns. The results showed that the historical BC samples were substantially oxidized after 130 years in soils as compared to new BC or BC incubated for one year. The major alterations by natural oxidation of BC included: (1) changes in elemental composition with increases in oxygen (O) from 7.2% in new BC to 24.8% in historical BC and decreases in C from 90.8% to 70.5%; (2) formation of oxygen-containing functional groups, particularly carboxylic and phenolic functional groups, and (3) disappearance of surface positive charge and evolution of surface negative charge after 12 months of incubation. Although time of exposure significantly increased natural oxidation of BC, a significant positive relationship between mean annual temperature (MAT) and BC oxidation (O/C ratio with r=0.83; P<0.01) explained that BC oxidation was increased by 87mmolekgC (super -1) per unit Celsius increase in MAT. This long-term oxidation was more pronounced on BC surfaces than for entire particles, and responded 7-fold stronger to increases in MAT. Our results also indicated that oxidation of BC was more important than adsorption of non-BC. Thus, natural oxidation of BC may play an important role in the effects of BC on soil biogeochemistry.

AN - 36793242; 3490660 AB - It is widely acknowledged that technological change can substantially reduce the costs of stabilizing atmospheric concentrations of greenhouse gases. This paper discusses the sources of technological change and the representations of these sources in formal models of energy and the environment. The paper distinguishes between three major sources of technological change-R&D, learning-by-doing and spillovers-and introduces a conceptual framework for linking modeling approaches to assumptions about these real-world sources. A selective review of modeling approaches, including those employing exogenous technological change, suggests that most formal models have meaningful real-world interpretations that focus on a subset of possible sources of technological change while downplaying the roles of others.

S17E is a 62-residue protein conserved in archaea and eukaryotes and has no counterparts in bacteria. Mammalian S17E is a phosphoprotein component of eukaryotic ribosomes. Archaeal S17E proteins range from 59 to 79 amino acids, and are about half the length of the eukaryotic homologs which have an additional C-terminal region. Here we report the three-dimensional solution structure of S17E. S17E folds into a small three-helix bundle strikingly similar to the FF domain of human HYPA/FBP11, a novel phosphopeptide-binding fold. S17E bears a conserved positively charged surface acting as a robust scaffold for molecular recognition. The structure of M. thermoautotrophicum S17E provides a template for homology modeling of eukaryotic S17E proteins in the family.

L40E is a 56-residue, highly basic protein that contains a C4 zinc finger motif, CRKC_X sub(10)_CRRC. Homologs are found in both archaea and eukaryotes but are not present in bacteria. Eukaryotic genomes encode L40E as a ubiquitin-fusion protein. L40E was absent from the crystal structure of euryarchaeota 50S ribosomal subunit. Here we report the three-dimensional solution structure of L40E by NMR spectroscopy. The structure of L40E is a three-stranded beta -sheet with a simple beta 2 beta 1 beta 3 topology. There are two unique characteristics revealed by the structure. First, a large and ordered beta 2- beta 3 loop twists to pack across the one side of the protein. L40E contains a buried polar cluster comprising Lys19, Lys20, Cys22, Asn29, and Cys36. Second, the surface of L40E is almost entirely positively charged. Ten conserved basic residues are positioned on the two sides of the surface. It is likely that binding of zinc is essential in stabilizing the tertiary structure of L40E to act as a scaffold to create a broad positively charged surface for RNA and/or protein recognition.

The most popular approaches to this challenge make use of the simplifying assumption that similar functional molecules, or proteins, sometimes have similar composition, or sequence. However, these algorithms often fail to identify remote homologs (proteins with similar function but dissimilar sequence) which often are a significant fraction of the total homolog collection for a given sequence. We introduce a Support Vector Machine (SVM)-based tool to detect homology using semi-supervised iterative learning (SVM-HUSTLE) that identifies significantly more remote homologs than current state-of-the-art sequence or cluster-based methods. As opposed to building profiles or position specific scoring matrices, SVM-HUSTLE builds an SVM classifier for a query sequence by training on a collection of representative high-confidence training sets, recruits additional sequences and assigns a statistical measure of homology between a pair of sequences. SVM-HUSTLE combines principles of semi-supervised learning theory with statistical sampling to create many concurrent classifiers to iteratively detect and refine, on-the-fly, patterns indicating homology. RESULTS: When compared against existing methods for identifying protein homologs (BLAST, PSI-BLAST, COMPASS, PROF_SIM, RANKPROP and their variants) on two different benchmark datasets SVM-HUSTLE significantly outperforms each of the above methods using the most stringent ROC sub(1) statistic with P-values less than 1e-20. SVM-HUSTLE also yields results comparable to HHSearch but at a substantially reduced computational cost since we do not require the construction of HMMs. AVAILABILITY: The software executable to run SVM-HUSTLE can be downloaded from http://www.sysbio.org/sysbio/networkbio/svm_hustle.

This broad comparative analysis is carried out for the following climate change mitigation strategies: supply-side and end-use efficiency improvements, terrestrial and geological carbon sequestration, CO sub(2) ocean disposal and iron fertilization, nuclear power, and renewable energy generation from biomass, passive solar, solar thermal, photovoltaics, hydroelectric and wind. In addition, because of the inherent problems of conducting an objective comparative cost-benefit analysis, 2 non- technological solutions to global warming are also discussed: curbing population growth and transitioning to a steady-state economy.

However, it remains uncertain whether the transcriptomic profiles resulting from exposure to a mixture have patterns of altered gene expression that contain identifiable contributions from each toxicant component. We exposed isogenic rainbow trout Onchorynchus mykiss, to sublethal levels of ethynylestradiol, 2,2,4,4-tetrabromodiphenyl ether, and chromium VI or to a mixture of all three toxicants Fluorescently labeled complementary DNA (cDNA) were generated and hybridized against a commercially available Salmonid array spotted with 16,000 cDNAs. Data were analyzed using analysis of variance (p < 0.05) with a Benjamani-Hochberg multiple test correction (Genespring [Agilent] software package) to identify up and downregulated genes. Gene clustering patterns that can be used as "expression signatures" were determined using hierarchical cluster analysis. The gene ontology terms associated with significantly altered genes were also used to identify functional groups that were associated with toxicant exposure. Cross-ontological analytics approach was used to assign functional annotations to genes with "unknown" function. Our analysis indicates that transcriptomic profiles resulting from the mixture exposure resemble those of the individual contaminant exposures, but are not a simple additive list. However, patterns of altered genes representative of each component of the mixture are clearly discernible, and the functional classes of genes altered represent the individual components of the mixture. These findings indicate that the use of microarrays to identify transcriptomic profiles may aid in the identification of key stressors within a chemical mixture, ultimately improving environmental assessment.

AN - 70341775; 18302046 AB - Acetaldehyde is an important intermediate in the chemical synthesis and normal oxidative metabolism of several industrially important compounds, including ethanol, ethyl acetate, and vinyl acetate. Chronic inhalation of acetaldehyde leads to degeneration of the olfactory and respiratory epithelium in rats at concentrations > 50 ppm (90 day exposure) and respiratory and olfactory nasal tumors at concentrations > or = 750 ppm, the lowest concentration tested in the 2-yr chronic bioassay. Differences in the anatomy and biochemistry of the rodent and human nose, including polymorphisms in human high-affinity acetaldehyde dehydrogenase (ALDH2), are important considerations for interspecies extrapolations in the risk assessment of acetaldehyde. A physiologically based pharmacokinetic model of rat and human nasal tissues was constructed for acetaldehyde to support a dosimetry-based risk assessment for acetaldehyde (Dorman et al., 2008). The rodent model was developed using published metabolic constants and calibrated using upper-respiratory-tract acetaldehyde extraction data. The human nasal model incorporates previously published tissue volumes, blood flows, and acetaldehyde metabolic constants. ALDH2 polymorphisms were represented in the human model as reduced rates of acetaldehyde metabolism. Steady-state dorsal olfactory epithelial tissue acetaldehyde concentrations in the rat were predicted to be 409, 6287, and 12,634 microM at noncytotoxic (50 ppm), and cytotoxic/tumorigenic exposure concentrations (750 and 1500 ppm), respectively. The human equivalent concentration (HEC) of the rat no-observed-adverse-effect level (NOAEL) of 50 ppm, based on steady-state acetaldehyde concentrations from continual exposures, was 67 ppm. Respiratory and olfactory epithelial tissue acetaldehyde and H(+) (pH) concentrations were largely linear functions of exposure in both species. The impact of presumed ALDH2 polymorphisms on human olfactory tissue concentrations was negligible; the high-affinity, low-capacity ALDH2 does not contribute significantly to acetaldehyde metabolism in the nasal tissues. The human equivalent acetaldehyde concentration for homozygous low activity was 66 ppm, 1.5% lower than for the homozygous full activity phenotype. The rat and human acetaldehyde PBPK models developed here can also be used as a bridge between acetaldehyde dose-response and mode-of-action data as well as between similar databases for other acetaldehyde-producing nasal toxicants.

Exclusion of conservative tracers and a decrease in U sorption compared with what was predicted by the mass-averaged equilibrium distribution coefficient (K (sub d-mass-avg) ) was observed in sediment mixtures where the mass fraction of silt loam was 10%. This is consistent with behavior that was previously reported for coarse and fine sand separates. No exclusion of the conservative tracer, as predicted for the moderate water content range, was measured during unsaturated transport in sediment mixtures that contained 30% or more silt loam by mass. Sorption under unsaturated conditions was greater than predicted based on the batch sorption measurement of K (sub d-mass-avg) value, however, which suggests that the fine-textured silt was in contact with the mobile water domain. This is the first evidence linking sorption to transport in a particular water domain. Results of this investigation demonstrate that the interaction between the geochemical and hydrodynamic processes has a profound effect on transport in unsaturated sediments. Definition of the fraction of mobile water was especially important for defining the front of the breakthrough curve, which is integral to predicting the arrival time of solutes at a particular depth and location in the sediment.

Previous research during one spawning season (2000) suggested that these species selected spawning habitats based on differences in hyporheic temperature and vertical hydraulic gradient (VHG). In this study we confirmed the spatial segregation of spawning based on hyporheic characteristics over 4 years (2001-2004) and examined the effects of load-following operations (power generation to meet short-term electrical demand) at Bonneville Dam on hyporheic function and characteristics. We found that during the study period hyporheic temperature and VHG in chum salmon spawning areas were highly variable during periods of load-following operation, when river levels fluctuated. In contrast, hyporheic water temperature and VHG within chum salmon spawning areas fluctuated less when river levels were not changing owing to load-following operation. Variable temperature and VHG could affect chum and fall Chinook salmon spawning segregation and incubation success by altering the cues each species uses to select redd sites.

Here we demonstrate that dissolved extracellular DNA can serve as a sole source of phosphorus, as well as carbon and energy, for metal-reducing bacteria of the genus SHEWANELLA: Shewanella oneidensis MR-1, Shewanella putrefaciens CN32, and Shewanella sp. strain W3-18-1 all grew with DNA but displayed different growth rates. W3-18-1 exhibited the highest growth rate with DNA. While strain W3-18-1 displayed Ca super(2+)-independent DNA utilization, both CN32 and MR-1 required millimolar concentrations of Ca super(2+) for growth with DNA. For S. oneidensis MR-1, the utilization of DNA as a sole source of phosphorus is linked to the activities of extracellular phosphatase(s) and a Ca super(2+)-dependent nuclease(s), which are regulated by phosphorus availability. Mass spectrometry analysis of the extracellular proteome of MR-1 identified one putative endonuclease (SO1844), a predicted UshA (bifunctional UDP-sugar hydrolase/5' nucleotidase), a predicted PhoX (calcium-activated alkaline phosphatase), and a predicted CpdB (bifunctional 2',3' cyclic nucleotide 2' phosphodiesterase/3' nucleotidase), all of which could play important roles in the extracellular degradation of DNA under phosphorus-limiting conditions. Overall, the results of this study suggest that the ability to use exogenous DNA as the sole source of phosphorus is widespread among the shewanellae, and perhaps among all prokaryotes, and may be especially important for nutrient cycling in metal-reducing environments.

AN - 70242479; 18230215 AB - Hexavalent chromium Cr(VI) is a notorious ground water contaminant toxic to humans and animals. Assessment of an exposure risk for aquatic receptors necessitates frequent Cr(VI) concentration data from a range of surface and groundwater locations at Cr(VI) contamination sites. In this work, we demonstrate that enhanced ultraviolet-visible (UV-vis) spectroscopy using a liquid waveguide capillary cell (LWCC) offers an easy-to-use and economical methodology for the determination of chromate anion CrO(4)(2-) in Hanford natural waters without chemical pretreatment and generation of hazardous waste. Direct determination of CrO(4)(2-) in actual surface and ground water samples with the complexities of competing ions, dissolved organics, and other potential interfering agents was achieved by measuring the chromate optical absorbance at 372 nm. For a 100 cm path length LWCC, the detection limit for chromate was found to be as low as 0.073 ppb. A quantitative relationship between the intensity of the absorbance signal and water pH allowed for the straightforward calculation of total Cr(VI) content in natural water. The described method is applicable for in-field monitoring of Cr(VI) in environmental water samples at trace levels.

AN - 69742870; 18942695 AB - A nanoparticle-based electrochemical immunosensor has been developed for the detection of phosphorylated acetylcholinesterase (AChE), which is a potential biomarker of exposure to organophosphate (OP) pesticides and chemical warfare nerve agents. Zirconia nanoparticles (ZrO(2) NPs) were used as selective sorbents to capture the phosphorylated AChE adduct, and quantum dots (ZnS@CdS, QDs) were used as tags to label monoclonal anti-AChE antibody to quantify the immunorecognition events. The sandwich-like immunoreactions were performed among the ZrO(2) NPs, which were pre-coated on a screen printed electrode (SPE) by electrodeposition, phosphorylated AChE and QD-anti-AChE. The captured QD tags were determined on the SPE by electrochemical stripping analysis of its metallic component (cadmium) after an acid-dissolution step. Paraoxon was used as the model OP insecticide to prepare the phosphorylated AChE adducts to demonstrate proof of principle for the sensor. The phosphorylated AChE adduct was characterized by Fourier transform infrared spectroscopy (FTIR) and mass spectroscopy. The binding affinity of anti-AChE to the phosphorylated AChE was validated with an enzyme-linked immunosorbent assay. The parameters (e.g., amount of ZrO(2) NP, QD-anti-AChE concentration,) that govern the electrochemical response of immunosensors were optimized. The voltammetric response of the immunosensor is highly linear over the range of 10 pM to 4 nM phosphorylated AChE, and the limit of detection is estimated to be 8.0 pM. The immunosensor also successfully detected phosphorylated AChE in human plasma. This new nanoparticle-based electrochemical immunosensor provides an opportunity to develop field-deployable, sensitive, and quantitative biosensors for monitoring exposure to a variety of OP pesticides and nerve agents.

We applied CP MAS (super 13) C NMR spectroscopy and radiocarbon modeling to soil density fractions from the top 10 cm to track changes in C chemistry and turnover during secondary forest establishment on former pastures. Our results showed that inter-aggregate, unattached, particulate organic C (free light fraction) and particulate C located inside soil aggregates (occluded light fraction) represent distinct soil C pools with different chemical composition and turnover rates. The signal intensity of the O-alkyl region, primarily representing carbohydrates, decreased, and alkyl C, attributed to recalcitrant waxy compounds and microbially resynthesized lipids, increased from plant litter to soil organic matter and with incorporation into soil aggregates. The alkyl/O-alkyl ratio, a common index of humification, was higher in the occluded than in the free light fraction. Greater variability in the chemical makeup of the occluded light fraction suggests that it represents material in varied stages of decomposition. Mean residence times ( (super 14) C-based) of the free light fraction were significantly shorter (4+ or -1 years) than for the heavy fraction. We report two scenarios for the occluded light fraction, one fast-cycling in which the occluded and free light fractions have similar turnover rates, and one slow-cycling, in which the occluded light fraction resembles the heavy fraction. Mean residence times of the occluded light fraction and heavy fraction in active pastures and 10-year old secondary forests in the earliest stage of succession were longer than in older secondary forests and primary forests. This is likely due to a preferential loss of physically unprotected C of more labile composition in the pastures and in the youngest successional forests, resulting in an increase in the dominance of slow-cycling C pools. Soil carbon turnover rates of the mineral-associated C in secondary forests recovering from abandoned pasture resembled those of primary forests in as little as 20 years of succession.

The methodology extends Maximum Likelihood Bayesian Model Averaging (MLBMA) to account jointly for uncertainties due to the conceptual-mathematical basis of models, model parameters, and the scenarios to which the models are applied. Conceptual uncertainty was represented by postulating four alternative models of hydrogeology and uranium adsorption. Parameter uncertainties were represented by estimation covariances resulting from the joint calibration of each model to observed heads and uranium concentration. Posterior model probability was dominated by one model. Results demonstrated the role of model complexity and fidelity to observed system behaviour in determining model probabilities, as well as the impact of prior information. Two scenarios representing alternative future behaviour of the Columbia River adjacent to the site were considered. Predictive simulations carried out with the calibrated models illustrated the computation of model- and scenario-averaged predictions and how results can be displayed to clearly indicate the individual contributions to predictive uncertainty of the model, parameter, and scenario uncertainties. The application demonstrated the practicability of applying a comprehensive uncertainty assessment to large-scale, detailed groundwater flow and transport modelling.

Herein, we report on the development and characterization of a TOF MS instrument with improved sensitivity equipped with an electrodynamic ion funnel trap (IFT) that employs an automated gain control (AGC) capability. The IFT-TOF MS was coupled to a reversed-phase capillary liquid chromatography (RPLC) separation and evaluated in experiments with complex proteolytic digests. When applied to a global tryptic digest of Shewanella oneidensis proteins, an order-of-magnitude increase in sensitivity compared to that of the conventional continuous mode of operation was achieved due to efficient ion accumulation prior to TOF MS analysis. As a result of this sensitivity improvement and related improvement in mass measurement accuracy, the number of unique peptides identified in the AGC-IFT mode was 5-fold greater than that obtained in the continuous mode.

Many traditional graph algorithms such as k-clique, k-coloring, and subgraph matching have great potential as analysis techniques for newly available data in biology. Yet, as the amount of genomic and bionetwork information rapidly grows, scientists need advanced new computational strategies and tools for dealing with the complexities of the bionetwork analysis and the volume of the data. Results We introduce a computational framework for graph analysis called the Biological Graph Environment (BioGraphE), which provides a general, scalable integration platform for connecting graph problems in biology to optimized computational solvers and high-performance systems. This framework enables biology researchers and computational scientists to identify and deploy network analysis applications and to easily connect them to efficient and powerful computational software and hardware that are specifically designed and tuned to solve complex graph problems. In our particular application of BioGraphE to support network analysis in genome biology, we investigate the use of a Boolean satisfiability solver known as Survey Propagation as a core computational solver executing on standard high-performance parallel systems, as well as multi-threaded architectures. Conclusion In our application of BioGraphE to conduct bionetwork analysis of homology networks, we found that BioGraphE and a custom, parallel implementation of the Survey Propagation SAT solver were capable of solving very large bionetwork problems at high rates of execution on different high-performance computing platforms.

The objective of this research was to evaluate the effects of Hells Canyon Dam discharge operations on hydrologic exchange flows between the river and riverbed in Snake River fall Chinook salmon spawning areas. Interactions between river water and pore water within the upper 1 m of the riverbed were quantified through the use of self-contained temperature and water level data loggers suspended inside of piezometers. The data were recorded at 20 min intervals over a period of 200 days when the mean daily discharge was 218-605 m3 s-1, with hourly stage changes as large as 1*9 m. Differences in head pressure between the river and riverbed were small, often within ± 2 cm. Measured temperature gradients in the riverbed indicated significant interactions between the surface and subsurface water. At the majority of sites, neither hydraulic nor temperature gradients were significantly affected by either short- or long-term changes in discharge operations from Hells Canyon Dam. Only 2 of 14 study sites exhibited acute flux reversals between the river and riverbed resulting from short-term, large magnitude changes in discharge. The findings suggest that local scale measurements may not be wholly explanatory of the hydrological exchange between the river and riverbed. The processes controlling surface water exchange at the study sites are likely to be bedform-induced advective pumping, turbulence at the riverbed surface, and large-scale hydraulic gradients along the longitudinal profile of the riverbed. By incorporating the knowledge of hydrological exchange processes into water management planning, regional agencies will be better prepared to manage the limited water resources among competing priorities that include salmon recovery, flood control, irrigation supply, hydropower production, and recreation.

AN - 20894588; 8131294 AB - For extremely ionizing radiation-resistant bacteria, survival has been attributed to protection of proteins from oxidative damage during irradiation, with the result that repair systems survive and function with far greater efficiency during recovery than in sensitive bacteria. Here we examined the relationship between survival of dry-climate soil bacteria and the level of cellular protein oxidation induced by desiccation. Bacteria were isolated from surface soils of the shrub-steppe of the US Department of Energy's Hanford Site in Washington State. A total of 63 isolates were used for phylogenetic analysis. The majority of isolates were closely related to members of the genus Deinococcus, with Chelatococcus, Methylobacterium and Bosea also among the genera identified. Desiccation-resistant isolates accumulated high intracellular manganese and low iron concentrations compared to sensitive bacteria. In vivo, proteins of desiccation-resistant bacteria were protected from oxidative modifications that introduce carbonyl groups in sensitive bacteria during drying. We present the case that survival of bacteria that inhabit dry-climate soils are highly dependent on mechanisms, which limit protein oxidation during dehydration.

A key challenge when working with multiple, closely spaced ESI emitters is overcoming the deleterious effects caused by electrical interference among neighboring emitters. Individual emitters can experience different electric fields depending on their relative position in the array, such that it becomes difficult to operate all of the emitters optimally for a given applied potential. In this work, we have developed multi-nanoESI emitters arranged with a circular pattern, which enable the constituent emitters to experience a uniform electric field. The performance of the circular emitter array was compared to a single emitter and to a previously developed linear emitter array, which verified that improved electric field uniformity was achieved with the circular arrangement. The circular arrays were also interfaced with a mass spectrometer via a matching multicapillary inlet, and the results were compared with those obtained using a single emitter. By minimizing interemitter electric field inhomogeneities, much larger arrays having closer emitter spacing should be feasible.

The sequences of these peptides contained the highly conserved amino acid motif, Ser/Thr- hydrophobic/aromatic-Ser/Thr-Pro-Ser/Thr. To better understand the nature of the peptide-metal oxide binding demonstrated by these experiments, molecular dynamics simulations were carried out for Ser-Pro-Ser at a hematite surface. These simulations show that hydrogen bonding occurs between the two serine amino acids and the hydroxylated hematite surface and that the presence of proline between the hydroxide residues restricts the peptide flexibility, thereby inducing a structural-binding motif. A search of published sequence data revealed that the binding motif (Ser/Thr-Pro-Ser/Thr) is adjacent to the terminal heme-binding domain of both OmcA and MtrC, which are outer membrane cytochromes from the metal-reducing bacterium Shewanella oneidensis MR-1. The entire five amino acid consensus sequence (Ser/Thr-hydrophobic/aromatic- Ser/Thr-Pro-Ser/Thr) was also found as multiple copies in the primary sequences of metal-oxide binding proteins Sil1 and Sil2 from Thalassiosira pseudonana. We suggest that this motif constitutes a natural metal-oxide binding archetype that could be exploited in enzyme-based biofuel cell design and approaches to synthesize tailored metal-oxide nanostructures.

This system performs multiple LC separations in parallel, but staggers each of them such that the data-rich region of each separation is sampled sequentially. By allowing nearly continuous data acquisition, this design maximizes the use of the mass spectrometer. Each analytical column is connected to a corresponding ESI emitter in order to avoid the use of postcolumn switching and associated dead volume issues. Encoding translation stages are employed to sequentially position the emitters at the MS inlet. The high reproducibility of this system is demonstrated using consecutive analyses of global tryptic digest of the microbe Shewanella oneidensis.

The region was the study domain for the 2006 MAX-MEX experiment, which was a component of the MILAGRO campaign. The results are used to identify periods when biomass burning was likely to have had a significant impact on the concentrations of elemental carbon at two sites, T1 and T2, downwind of the city, and when emissions from the Mexico City Metropolitan Area (MCMA) were likely to have been more important. They are also used to estimate the median ages of EC affecting the specific absorption of light, alpha sub(ABS), at 870 nm as well as to identify periods when the urban plume from the MCMA was likely to have been advected over T1 and T2. Median EC ages at T1 and T2 are substantially larger during the day than at night. Values of alpha sub(ABS) at T1, the nearer of the two sites to Mexico City, were smaller at night and increased rapidly after mid-morning, peaking in the mid-afternoon. The behavior is attributed to the coating of aerosols with substances such as sulfate or organic carbon during daylight hours, but such coating appears to be limited or absent at night. Evidence for this is provided by scanning electron microscopy images of aerosols collected at the sampling sites. During daylight hours the values of alpha sub(ABS) did not increase with aerosol age for median ages in the range of 1-4 h. There is some evidence for absorption increasing as aerosols were advected from T1 to T2 but the statistical significance of that result is not strong.

We report a robust, integrated poly(dimethylsiloxane) microchip interface for ESI-MS using simple and widely accessible microfabrication procedures. The interface uses an auxiliary channel to provide electrical contact for the stable cone-jet electrospray without sample loss or dilution. The electric field at the channel terminus is enhanced by two vertical cuts that cause the interface to taper to a line rather than to a point, and the formation of a small Taylor cone at the channel exit ensures subnanoliter postcolumn dead volumes. Cone-jet mode electrospray was demonstrated for up to 90% aqueous solutions and for extended durations. Comparable ESI-MS sensitivities were achieved using both microchip and conventional fused silica capillary emitters, but stable cone-jet mode electrosprays could be established over a far broader range of flow rates (from 50-1000 nL/min) and applied potentials using the microchip emitters. This attribute of the microchip emitter should simplify electrospray optimization and make the stable electrospray more resistant to external perturbations.

The thermodynamic cycle incorrectly assumed that the energy difference between the (H sub(2)O) sub(n) super(+) rarr (H sub(2)O) sub(n-1)H super(+) + OH super(bull) asymptotes (the relaxation energy) was zero. We show that these relaxation energies are large and cannot be neglected in the analysis. Thus, the neutral water cluster monomer dissociation energies cannot be directly determined from the measured ionization potentials because they are themselves involved in the appropriate thermodynamic cycle.

The use of ion trapping and accumulation approaches prior to the ion mobility drift tube has demonstrated significant gains over discrete sampling from continuous sources but have traditionally relied upon a signal averaging (SA) to attain analytically useful signal-to-noise ratios (SNR). Multiplexed (MP) techniques based upon the Hadamard transform offer an alternative experimental approach by which ion utilization efficiency can be elevated from similar to 1 to similar to 50%. Recently, our research group demonstrated a unique multiplexed ion mobility time-of-flight (MP-IMS-TOF) approach that incorporates ion trapping and can extend ion utilization efficiency beyond 50%. However, the spectral reconstruction of the multiplexed signal using this experiment approach requires the use of sample-specific weighting designs. Such general weighting designs have been shown to significantly enhance ion utilization efficiency using this MP technique, but cannot be universally applied. By modifying both the ion trapping and the pseudorandom sequence (PRS) used for the MP experiment, we have eliminated the need for complex weighting matrices. For both simple and complex mixtures, SNR enhancements of up to 13 were routinely observed as compared to the SA-IMS- TOF approach. In addition, this new class of PRS provides a 2-fold enhancement in the number of ion gate pulses per unit time compared to the traditional HT-IMS experiment.

To take full advantage of high mass measurement accuracy instruments, it is necessary to limit systematic mass measurement errors. It is well known that errors in m/z measurements can be affected by experimental parameters that include, for example, outdated calibration coefficients, ion intensity, and temperature changes during the measurement. Traditionally, these variations have been corrected through the use of internal calibrants (well-characterized standards introduced with the sample being analyzed). In this paper, we describe an alternative approach where the calibration is provided through the use of a priori knowledge of the sample being analyzed. Such an approach has previously been demonstrated based on the dependence of systematic error on m/z alone. To incorporate additional explanatory variables, we employed multidimensional, nonparametric regression models, which were evaluated using several commercially available instruments. The applied approach is shown to remove any noticeable biases from the overall mass measurement errors and decreases the overall standard deviation of the mass measurement error distribution by 1.2-2-fold, depending on instrument type. Subsequent reduction of the random errors based on multiple measurements over consecutive spectra further improves accuracy and results in an overall decrease of the standard deviation by 1.8-3.7-fold. This new procedure will decrease the false discovery rates for peptide identifications using high-accuracy mass measurements.

High fish-passage effectiveness of surface-flow outlets (SFOs) relative to the spillway and turbines suggested that juvenile salmonids preferentially selected surface outlets over adjacent turbines. Seasonal estimates showed that median combined effectiveness of SFOs (7.8) was 7.1 times higher than that of the spillway (1.1) and 9.8 times higher than that of turbines (0.8). Islands prevented the spillway from attracting fish from either powerhouse forebay, something that does not occur at most hydropower projects. Regression analyses indicated that percent flow passing a specific route explained from 50% to 97% of fish-passage variation, and relations were useful for evaluating fish-passage alternatives. Fitted curves for surface-passage routes, including the sluiceway at Powerhouse 1 (B1) and Powerhouse 2 (B2) were much steeper at low percent flow (2-15%) than were curves for the spillway or turbines. Regressions indicate that increasing surface-flow percentages of B1 flow from 1% to 10% could increase B1 sluiceway-passage efficiency from 40% to 83%. Increasing B2 flow to the B2 sluiceway from 4% to 15% could increase B2 sluiceway passage efficiency from 31% to 62%. Without spill, about 50% of fish passed by nonturbine routes. We recommend increasing percent flow to the B1- and B2-sluiceways because those surface-flow outlets are highly effective, adjacent to turbines, and capable of attracting smolts away from turbines.

Using irradiance data from a Multi-Filter Rotating Shadowband Radiometer (MFRSR) and an actinic flux spectroradiometer (SR), we derive aerosol single scattering albedo, ϖ sub(0, lambda), as a function of wavelength, I". We find that in the near-UV spectral range (250 to 400 nm) ϖ sub(0, lambda) is much lower compared to ϖ sub(0, lambda) at 500 nm indicating enhanced absorption in the near-UV range. Absorption by elemental carbon, dust, or gas cannot account for this enhanced absorption leaving the organic carbon component of the aerosol (OA) as the most likely absorber. We use data from a surface deployed Aerodyne Aerosol Mass Spectrometer (AMS) along with the inferred ϖ sub(0, lambda) to estimate the Mass Absorption Cross section (MAC) for the organic aerosol. We find that the MAC is about 10.5 m super(2)/g at 300 nm and falls close to zero at about 500 nm; values that are roughly consistent with other estimates of organic aerosol MAC. These MAC values can be considered as "radiatively correct", because when used in radiative transfer calculations, the calculated irradiances/actinic fluxes match those measured at the wavelengths considered here. For an illustrative case study described here, we estimate that the light absorption by the "brown" (organic) carbonaceous aerosol can add about 40% to the light absorption of black carbon in Mexico City. This contribution will vary depending on the relative abundance of organic aerosol relative to black carbon. Furthermore, our analysis indicates that organic aerosol would slow down photochemistry by selectively scavenging the light reaching the ground at those wavelengths that drive photochemical reactions. Finally, satellite retrievals of trace gases that are used to infer emissions currently assume that the MAC of organic carbon is zero. For trace gases that are retrieved using wavelengths shorter then 420 nm (i.e. SO sub(2), HCHO, halogenoxides, NO sub(2)), the assumption of non-zero MAC values will induce an upward correction to the inferred emissions. This assumption will be particularly relevant in polluted urban atmospheres and areas of biomass burning where organic aerosols are particularly abundant.

In order to understand the dominant geochemical reactions and transport processes that occurred during the initial infiltration and to help understand current spatial distribution, we simulated the waste liquid spilling event in laboratory sediment columns using synthesized metal waste solution. We found that, as the plume propagated through sediments, pH decreased greatly (as much as 4 units) at the moving plume front. Infiltration flow rates strongly affect U behavior. Slower flow rates resulted in higher sediment-associated U concentrations, and higher flow rates (>=5 cm/day) permitted practically unretarded U transport. Therefore, given the very high K sub(sat) of most of Hanford formation, the low permeability zones within the sediment could have been most important in retaining high concentrations of U during initial release into the vadose zone. Massive amount of colloids, including U- colloids, formed at the plume fronts. Total U concentrations (aqueous and colloid) within plume fronts exceeded the source concentration by up to 5- fold. Uranium colloid formation and accumulation at the neutralized plume front could be one mechanism responsible for highly heterogeneous U distribution observed in the contaminated Hanford vadose zone.

Here we report the activity and crystal structure for DR_0079, the first Nudix hydrolase observed to have a marked preference for cytosine ribonucleoside 5'-diphosphate (CDP) and cytosine ribonucleoside 5'-triphosphate (CTP). After CDP and CTP, the next most preferred substrates for DR_0079, with a relative activity of Mn super(2+) > Co super(2+)). The biochemical data are discussed with reference to the crystal structure for DR_0079 that was determined in the metal-free form at 1.9 Aa resolution. The protein contains nine b-strands, three a-helices, and two 3 sub(10)-helices organized into three subdomains: an N-terminal b-sheet, a central Nudix core, and a C-terminal helix-turn-helix motif. As observed for all known structures of Nudix hydrolases, the a-helix of the "Nudix box" is one of two helices that sandwich a "four-strand" mixed b-sheet. To identify residues potentially involved in metal and substrate binding, NMR chemical shift mapping experiments were performed on super(15)N-labeled DR_0079 with the paramagnetic divalent cation Co super(2+) and the nonhydrolyzable substrate thymidine 5'-O-(a,b-methylenediphosphate) and the results mapped onto the crystal structure.

Here, we report the production of an extensive extracellular network of filamentous, arsenic-sulfide (As-S) nanotubes (20-100 nm in diameter by nearly equal 30 mu m in length) by the dissimilatory metal-reducing bacterium Shewanella sp. HN-41. The As-S nanotubes, formed via the reduction of As(V) and S (sub 2) O (sub 3) (super 2-) , were initially amorphous As (sub 2) S (sub 3) but evolved with increasing incubation time toward polycrystalline phases of the chalcogenide minerals realgar (AsS) and duranusite (As (sub 4) S). Upon maturation, the As-S nanotubes behaved as metals and semiconductors in terms of their electrical and photoconductive properties, respectively. The As-S nanotubes produced by Shewanella may provide useful materials for novel nano- and opto-electronic devices.

AN - 70141367; 19206668 AB - The growing commerce in micro- and nanotechnology is expected to increase human exposure to submicrometer and nanoscale particles, including certain forms of amorphous silica. When inhaled, these particles are likely to reach the alveoli, where alveolar type II epithelial cells that are distinguished by apical microvilli are found. These cells play critical roles in the function of the alveoli and participate in the immune response to amorphous silica and other particles by releasing chemokines. The cellular interactions of the particles, which drive the cellular responses, are still unclear. Adverse effects of nanoparticles have been attributed, in part, to the unique properties of materials at the nanoscale. However, little is known about the cellular interactions of individual or small nanoparticle aggregates, mostly because of their tendency to agglomerate under experimental conditions. Here we investigate the interaction and internalization pathway of individual precipitated amorphous silica particles with specific surface properties and size, by following one particle at a time. We find that both 100 and 500 nm particles can take advantage of the actin turnover machinery within filopodia and microvilli-like structures to advance their way into alveolar type II epithelial cells. This pathway is strictly dependent on the positive surface charge of the particle and on the integrity of the actin filaments, unraveling the coupling of the particle with the intracellular environment across the cell membrane. The retrograde pathway brings a new mechanism by which positive surface charge supports particle recruitment, and potential subsequent toxicity, by polarized epithelial cells bearing microvilli.

AN - 69099664; 18186348 AB - Gold nanoparticle (Au-NP) enhanced voltammetric detection of Cr(VI) is developed for determination of trace amounts of Cr(VI) in an acetate buffer media (pH 4.6). The Au-NPs were electrodeposited onto a disposable screen printed electrode (SPE) via an electrodeposition step. It was found that the electrodeposited Au-NP has strong adsorption on Cr(VI) species, which results in an enhanced reduction current of Cr(VI). Compared with the bulk gold electrode, the reduction current of Cr(VI) was enhanced 10 times with the Au-NP-modified SPE electrode. Square wave voltammetric (SWV) measurement with the disposable Au-NP-modified SPE provides a fast, simple and sensitive detection of trace amounts of Cr(VI). The adsorption of Cr(VI) on Au-NP was characterized with voltammetry, X-ray photoelectron spectroscopy and ultraviolet spectra. The different parameters including the electrodepositing time, supporting electrolyte, and pH that govern the analytical performance of the electrode have been studied in detail and optimized. The detection limit of 5 microg L(-1) Cr (VI) was obtained under optimum experimental conditions. The performance of the sensor was successfully evaluated with river water samples spiked with Cr(VI), indicating this convenient and sensitive technique offers great promise for onsite environmental monitoring and biomonitoring of Cr(VI).

There has been little characterization or explanation of their formation. Along the Oregon coast such films were found on ephemeral pools where Fe(II)-rich groundwater (approximately 100 mu M Fe) has been discharged at the base of Pleistocene sand dunes. Fe(II) oxidized to Fe(III) at the air-water interface to form approximately 100-300 nm thick films. Analyses indicated that the films contained both Fe(III) and Fe(II) in a ratio of 3:1; Si was the other main cation; OH was the main anion and some C was also identified. The film morphology was flat under optical and electron microscopy with some attached floccules having a string-like morphology. Energy-filtered electron diffraction patterns showed three diffraction rings at 4.5, 2.6 and 1.4 Aa in some places and two rings (2.6 and 1.4 Aa) in others. Upon further oxidation the films became 2-line ferrihydrite. We are proposing the name "schwimmeisen" for the floating, mixed-valent Fe film.

For structured media where preferential flow prevails over the matrix flow, however, the Fe content determined from homogenized samples may not well represent the Fe available for biogeochemical reactions. In this study ammonium oxalate extraction was performed on a core of intact saprolite where physical structure was preserved. An unsaturated flow setup was modified with the intent of allowing the extraction under two pore tensions, 15 and 0 cm of water, although a malfunctioning vacuum regulator made this more difficult than anticipated. Approximately 85% of the oxalate- extractable Fe was contained within the finer pore domain (matrix potential larger than 15 cm). Less than 15.5% of the extracted Fe mass (an upper bound) was present in domains of pore tension less than15 cm. To the extent that Fe(III) oxides play an important role in contaminant biogeochemistry and solute transport, their distribution in structured subsurface media is critical to the understanding of these processes.

Carbon tetrachloride, a legacy waste, was used in the plutonium extraction process at the Hanford site in south-central Washington State. Vertical, depth-discrete groundwater samples were collected during well drilling throughout a 28-km super(2) region to determine the concentration of carbon tetrachloride present as a dissolved phase in the aquifer. Results indicate that high concentrations of carbon tetrachloride, three orders of magnitude above the allowable regulatory limit, are present at depths greater than 25 m beneath the water table. In support of future efforts to remediate the carbon tetrachloride contamination, it is imperative to locate the remaining chemical inventory, determine the vertical as well as the lateral distribution of this contaminant and its physical form. Depth-discrete aquifer characterization throughout the uppermost-unconfined aquifer system is providing this information and improving the understanding of the contaminant distribution and the hydrogeologic framework through which it moves.

In some pathogenic and metal-reducing bacteria, these genes are fused to form a bifunctional methionine sulfoxide reductase (i.e., MsrBA) enzyme. To investigate how gene fusion affects the substrate specificity and catalytic activities of Msr, we have cloned and expressed the MsrBA enzyme from Shewanella oneidensis, a metal-reducing bacterium and fish pathogen. For comparison, we also cloned and expressed the wild-type MsrA enzyme from S. oneidensis and a genetically engineered MsrB protein. MsrBA is able to completely reduce (i.e., repair) MetSO in the calcium regulatory protein calmodulin (CaM), while only partial repair is observed using both MsrA and MsrB enzymes together at 25 degree C. A restoration of the normal protein fold is observed co-incident with the repair of MetSO in oxidized CaM (CaM sub(ox) by MsrBA, as monitored by time-dependent increases in the anisotropy associated with the rigidly bound multiuse affinity probe 4',5'-bis(1,3,2-dithioarsolan-2-yl)fluorescein (FlAsH). Underlying the efficient repair of MetSO in CaM sub(ox) is the coordinate activity of the two catalytic domains in the MsrBA fusion protein, which results in a 1 order of magnitude rate enhancement in comparison to those of the individual MsrA or MsrB enzyme alone. The coordinate binding of both domains of MsrBA permits the full repair of all MetSO in CaM sub(ox). The common expression of Msr fusion proteins in bacterial pathogens is consistent with an important role for this enzyme activity in the maintenance of protein function necessary for bacterial survival under highly oxidizing conditions associated with pathogenesis or bioremediation.

Microanalytical based sensors that work with complex biomatrices such as blood, urine, or saliva are being developed and validated and will improve our ability to make definitive associations between chemical exposures and disease. Among toxic metals, lead continues to be one of the most problematic Despite considerable efforts to identify and eliminate Pb exposure sources, this metal remains a significant health concern, particularly for young children. Ongoing research focuses on the development of portable metal analyzers that have many advantages over current available technologies, thus potentially representing the next generation of toxic metal analyzers. In this article, we highlight the development and validation of two classes of metal analyzers for the voltammetric detection of Pb, including: a) an analyzer based on flow injection analysis and anodic stripping voltammetry at a mercury-film electrode, and b) Hg-free metal analyzers employing adsorptive stripping voltammetry and novel nanostructure materials that include the self-assembled monolayers on mesoporous supports and carbon nanotubes. These sensors have been optimized to detect Pb in urine, blood, and saliva as accurately as the state-of-the-art inductively coupled plasma-mass spectrometry with high repro-ducibility, and sensitivity allows. These improved and portable analytical sensor platforms will facilitate our ability to conduct biological monitoring programs to understand the relationship between chemical exposure assessment and disease outcomes.

Fluorescent in situ hybridization (FISH) supplies high-resolution spatial information and has been widely applied to study microbial communities at the rRNA level. While mRNA-targeted FISH has been popular for studying gene expression in eukaryotic cells, very little success has been achieved with prokaryotes. At present, detection of specific mRNAs in individual prokaryotic cells requires the use of in situ RT-PCR or tyramide signal amplification (TSA). In this study we used DNA oligonucleotide probes labeled with a single near-infrared dye in FISH assays to detect multi-copy plasmid-based and endogenous mRNA molecules in Escherichia coli and Shewanella oneidensis MR-1. We took advantage of the fact that there is much less background signal produced by biological materials and support matrices in the near-infrared spectrum and thus long camera exposure times could be used. In addition, we demonstrate that a combination of probes targeting both rRNA and mRNA could be successfully employed within the same FISH assay. These results, as well as ongoing R&D improvements in NIR and infrared dyes, indicate that the FISH approach we demonstrated could be applied in certain environmental settings to monitor gene expression in mixed populations.

As part of this field program, vertical concentration profiles were measured at approximately 1 km from the downtown ground-level tracer gas release locations. These profiles showed that the urban landscape was very effective in mixing the plume vertically. In general, the lowest concentration measured along the profile was within 50% of the highest concentration in any given 5-min measurement period. The general slope of the concentration profiles was bounded by a Gaussian distribution with Briggs's urban equations (stability classes D and E/F) for vertical dispersion. However, measured concentration maxima occurred at levels above the surface, which would not be predicted by Gaussian formulations. Variations in tracer concentration observed in the time series between different release periods were related to changes in wind direction as opposed to changes in turbulence. This was demonstrated using data from mobile analyzers that captured the width of the plume by traveling east to west along nearby streets. These mobile-van-analyzer data were also used to compute plume widths. Plume widths increased for wind directions at larger angles to the street grid, and a simple model comprising adjusted open-country dispersion coefficients and a street channeling component, were used to describe the measured widths. This dispersion dataset is a valuable asset not only for developing advanced tools for emergency-response situations in the event of a toxic release but also for refining air-quality models.

The six-degree-of-freedom (6DOF)Sensor Fish device is an autonomous sensor package that characterizes the physical conditionsand physical stresses to which fish are exposed when they pass through complex hydraulicenvironments. It has been used to identify the locations and operations where conditions aresevere enough to injure or kill fish. During the design process, a set of governing equationsof motion for the Sensor Fish was derived and simulated to understand the design implica-tions of instrument selection and placement within the body of the device. The Sensor Fishpackage includes three rotation sensors, three acceleration sensors, a pressure sensor, and atemperature sensor with a sampling frequency of 2,000 Hz. Its housing is constructed of clearpolycarbonate plastic. It is 24.5 mm in diameter and 90 mm in length and weighs about 43 g,similar to the size and density of a yearling salmon smolt. The accuracy of the pressure sensorwas determined to be within 0.2 psi. In laboratory acceptance tests, the relative errors of boththe linear acceleration and angular velocity measurements were determined to be less than5%. An exposure is defined as a significant event when the acceleration reaches predefinedthresholds. Based on the different characteristic of acceleration and rotation velocities, theexposure event is categorized as either a collision between the Sensor Fish and a solid struc-ture or shear caused by turbulence. Since its development in 2005, the 6DOF Sensor Fish hasbeen deployed successfully at many major dams in the United States.

AN - 69055440; 18075081 AB - The reductive dissolution of hematite (alpha-Fe2O3) was investigated in a flow-through system using AH2DS, a reduced form of anthraquinone-2,6-disulfonate (AQDS), which is often used as a model electron shuttling compound in studies of dissimilatory microbial reduction of iron oxides. Influent flow rate, pH, and Fe(II) and phosphate concentrations were varied to investigate the redox kinetics in a flow-through reactor. The hematite reduction rates decreased with increasing pH from 4.5 to 7.6 and decreased with decreasing flow rate. The rates also decreased with increasing influent concentration of Fe(II) or phosphate that formed surface complexes at the experimental pH. Mineral surface properties, Fe(II) complexation reactions, and ADDS sorption on hematite surfaces were independently investigated for interpreting hematite reduction kinetics. AH2DS sorption to hematite was inferred from the parallel measurements of AQDS and AH2DS sorption to alpha-Al2O3, a redox stable analog of alpha-Fe2O3. Decreasing Fe(ll) and increasing AH2DS sorption by controlling flow rate, influent pH, and Fe(II) and phosphate concentrations increased the rates of reductive dissolution. The rates were also affected by the redox reaction free energy when reductive dissolution approached equilibrium. This study demonstrated the importance of the geochemical variables for the reductive dissolution kinetics of iron oxides.

AN - 68485660; 17971412 AB - The chromosomal passenger complex (CPC) is a crucial regulator of chromosome, cytoskeleton and membrane dynamics during mitosis. Here, using liquid chromatography coupled to mass spectrometry (LC-MS), we identified phosphopeptides and phosphoprotein complexes recognized by a phosphorylation-specific antibody that labels the CPC. A mitotic phosphorylation motif {PX[G/T/S][L/M]S(P) P or WGLS(P) P} was identified by MS in 11 proteins, including FZR1 (Cdh1) and RIC8A-two proteins with potential links to the CPC. Phosphoprotein complexes contained the known CPC components INCENP, Aurora-B (Aurkb) and TD-60 (Rcc2, RCC1-like), as well as SMAD2, 14-3-3 proteins, PP2A and Cdk1 (Cdc2a), a probable kinase for this motif. Protein sequence analysis identified phosphorylation motifs in additional proteins, including SMAD2, PLK3 and INCENP. Mitotic SMAD2 and PLK3 phosphorylation was confirmed using phosphorylation-specific antibodies, and, in the case of Plk3, phosphorylation correlated with its localization to the mitotic apparatus and the midbody. A mutagenesis approach was used to show that INCENP phosphorylation is required for its localization to the midbody. These results provide evidence for a shared phosphorylation event that regulates localization of crucial proteins during mitosis.

AN - 68461222; 17929957 AB - To identify phosphoproteins regulated by the phosphoprotein phosphatase (PPP) family of S/T phosphatases, we performed a large-scale characterization of changes in protein phosphorylation on extracts from HeLa cells treated with or without calyculin A, a potent PPP enzyme inhibitor. A label-free comparative phosphoproteomics approach using immobilized metal ion affinity chromatography and targeted tandem mass spectrometry was employed to discover and identify signatures based upon distinctive changes in abundance. Overall, 232 proteins were identified as either direct or indirect targets for PPP enzyme regulation. Most of the present identifications represent novel PPP enzyme targets at the level of both phosphorylation site and protein. These include phosphorylation sites within signaling proteins such as p120 Catenin, A Kinase Anchoring Protein 8, JunB, and Type II Phosphatidyl Inositol 4 Kinase. These data can be used to define underlying signaling pathways and events regulated by the PPP family of S/T phosphatases.

Last updated - 2017-02-22 ER - TY - JOUR T1 - Effective hydraulic properties determined from transient unsaturated flow in anisotropic soils AN - 51100773; 2008-028993 AB - An important requirement for accurate modeling of field-scale unsaturated transport using local-scale parameters is a method to account for multiscale heterogeneity and the connectivity of the facies that control flow. A series of infiltration tests were conducted at the Hanford Site along a 60-m-long transect, instrumented at 1-m intervals to measure water content (theta ) and capillary pressure head (h) to quantify the spatial correlation structure of hydraulic properties and assess connectivity of the facies. Hydraulic parameters including the pore connectivity-tortuosity tensor (Li) were inversely estimated using the Subsurface Transport Over Multiple Phases (STOMP) numerical simulator coupled with the parameter estimation code, UCODE. Results show that six of eight parameters required for a modified van Genuchten-Mualem model could be inversely estimated using theta measured during transient infiltration from a surface line source and approximated prior information. Soils show evidence of saturation-dependent anisotropy that was well described with the connectivity tensor. Variability of the vertical saturated hydraulic conductivity, Ksv, was larger than the horizontal, Ksh. The autocorrelation ranges for Ksh, Ksv, the inverse of the air-entry value, alpha , and the horizontal connectivity, Lh, were between 2.4 and 4.6 m, whereas the van Genuchten shape parameter, n, and saturated water content, theta s, showed no autocorrelation. Accurate upscaling of hydraulic properties requires the correct assessment of the connectivity of facies.

The third aliquot contained bromide, D (sub 2) O, and (super 87) Sr. Movement of the tracers was monitored for 9 mo by measuring pore water compositions of samples from boreholes drilled 2 to 8 m from the injection point. Graded sedimentary layers acting as natural capillary barriers caused significant lateral spreading of the leak water. Shortly after injections were completed, D (sub 2) O was found at the 9- to 11-m depth at levels in excess of 50% of the tracer aliquot concentration, while sediment layers with elevated water content at the 6- to 7-m depth had less than 3% of the D (sub 2) O tracer concentration, suggesting deep penetration of the D (sub 2) O tracer and limited mixing between different aliquots of leak fluids. Initially, high bromide concentrations decreased more rapidly over time than D (sub 2) O, suggesting enhanced transport of bromide due to anion exclusion. No significant increase in (super 87) Sr was detected in the sampled pore water, indicating strong retardation of Sr by the sediments. These results highlight some of the processes strongly affecting chemical transport in the vadose zone and demonstrate the significant separation of contaminant plumes that can occur.

In this contribution, we first review our research using measured isotopic variations, due both to natural and site-related processes, of the elements H, O, N, Sr, and U, to study the interconnection between vadose zone and groundwater contamination at the Hanford Site in south-central Washington State. We follow this brief review with a presentation of new data pertaining to vadose zone and groundwater contamination in the Waste Management Area (WMA) T-TX-TY vicinity. Uranium isotopic data for the C3832 core (WMA TX) indicate the involvement of processed natural U fuel and link the observed U contamination to releases near single-shelled tank TX-104. The data also preclude contamination from an early 1970s TX-107 leak. In the case of the C4104 core (WMA T), the U isotopic data indicate a mixture of processed natural and enriched U fuels consistent with the major leak from T-106 in 1973. Uranium and strontium isotopic data for the cores also provide direct evidence for chemical interaction between high-pH waste fluid and sediment. Isotopic data (delta (super 15) N and delta (super 18) O) for groundwater nitrate contamination in multidepth samples just to the northeast of WMA T are distinct from that seen in surrounding wells and suggest tank waste (possibly from the 1973 T-106 event) as a source of very high 99Tc concentrations recently observed at the northeast corner of WMA T.

Three-dimensional modeling was conducted to enhance the current conceptual model of CT distribution beneath the major disposal site (216-Z-9). The simulations, using the STOMP code, focused on migration of dense nonaqueous phase liquid (DNAPL) consisting of CT and codisposed organics under scenarios with differing sediment properties, sediment distribution, waste properties, and waste disposal history. Simulation results support a conceptual model for CT distribution where CT in the DNAPL phase migrated primarily in a vertical direction below the disposal site and where some CT DNAPL likely migrated across the water table into the regional aquifer. Results also show that the lower permeability Cold Creek unit retained more CT DNAPL within the vadose zone than other hydrologic units during the infiltration and redistribution process. Due to the relatively high vapor pressure of the CT, the resulting vapor plumes are extensive and influenced by density-driven advection. Any continued migration of CT from the vadose zone to the groundwater is likely through interaction of vapor phase CT with the groundwater and not through continued DNAPL migration. Additional simulations assessed the impacts of soil vapor extraction (SVE) as a remediation method. These simulations showed rapid CT removal associated with the assumed local equilibrium of CT between the phases. Additional efforts are needed to enhance the understanding of rate-limited volatilization to improve simulation of the SVE process and to provide a basis for refining the design and operation of SVE systems.

The objective of the survey was to map the extent of the plume that resulted from the disposal activities approximately 50 yr earlier. The survey included six resistivity transects of at least 200 m, where each transect provided two-dimensional profile information of subsurface electrical properties. The results of the survey indicated that a low resistivity plume resides at a depth of approximately 25 to 44 m below ground surface. The target depth was calibrated with borehole data of pore-water electrical conductivity. Due to the high correlation of the pore-water electrical conductivity to nitrate concentration and the high correlation of measured apparent resistivity to pore-water electrical conductivity, inferences were made that proposed the spatial distribution of the apparent resistivity was due to the distribution of nitrate. Therefore, apparent resistivities were related to nitrate, which was subsequently rendered in three dimensions to show that the nitrate likely did not reach the water table and the bounds of the highest concentrations are directly beneath the collection of waste sites JF - Vadose Zone Journal AU - Rucker, Dale F AU - Fink, James B AU - Gee, Glendon W AU - Oostrom, Martinus AU - Freshley, M D AU - Rockhold, M L AU - Zachara, John M Y1 - 2007/11// PY - 2007 DA - November 2007 SP - 946 EP - 958 PB - Soil Science Society of America, Madison, WI VL - 6 IS - 4 KW - United States KW - geophysical surveys KW - contaminant plumes KW - halogens KW - waste disposal sites KW - unsaturated zone KW - mapping KW - fluorine KW - chloride ion KW - Benton County Washington KW - nitrate ion KW - soils KW - chlorine KW - technetium KW - high-resolution methods KW - Washington KW - sulfate ion KW - geophysical methods KW - electrical methods KW - pollution KW - Hanford Site KW - resistivity KW - southeastern Washington KW - inorganic materials KW - phosphate ion KW - detection KW - boreholes KW - liquid waste KW - fluoride ion KW - metals KW - surveys KW - Columbia Plateau KW - waste disposal KW - pore water KW - 20:Applied geophysics KW - 22:Environmental geology UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/51097387?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Ageorefmodule&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Vadose+Zone+Journal&rft.atitle=Inorganic+plume+delineation+using+surface+high-resolution+electrical+resistivity+at+the+BC+cribs+and+trenches+site%2C+Hanford&rft.au=Rucker%2C+Dale+F%3BFink%2C+James+B%3BGee%2C+Glendon+W%3BOostrom%2C+Martinus%3BFreshley%2C+M+D%3BRockhold%2C+M+L%3BZachara%2C+John+M&rft.aulast=Rucker&rft.aufirst=Dale&rft.date=2007-11-01&rft.volume=6&rft.issue=4&rft.spage=946&rft.isbn=&rft.btitle=&rft.title=Vadose+Zone+Journal&rft.issn=1539-1663&rft_id=info:doi/10.2136%2Fvzj2006.0169 L2 - http://www.vadosezonejournal.org LA - English DB - GeoRef N1 - Copyright - GeoRef, Copyright 2012, American Geosciences Institute.

The 200 Area sediments contained uranyl silicate mineralization (sodium boltwoodite) in restrictive microfractures in granitic clasts, in the vadose zone over a narrow range in depth. Well logging and column experiments indicated that tank wastes migrated deeper than observed in core samples. The 300 Area sediments included metatorbernite and uranium at low concentrations associated with detrital aluminosilicates, along with other mineral phases that could accommodate uranyl, such as uranophane and calcium carbonate. The association of contaminant uranyl with Hanford formation sediments provided a persistent source of uranium to groundwater. The results of both studies suggest that the formation of secondary solid uranyl-bearing phases influences the subsequent release of uranium to the environment and that our understanding of these processes and individual waste sites is incomplete.

These so-called tank wastes were initially thermally hot because of radioactive decay, and many exhibited extreme chemical character in terms of pH, salinity, and radionuclide concentration. At present, 67 of the 149 single shell tanks are suspected to have released over 1.9 million L of tank waste to the vadose zone, with most leak events occurring between 1950 and 1975. Boreholes have been placed through the largest vadose zone plumes to define the extent of contaminant migration and to develop conceptual models of processes governing the transformation, retardation, and overall transport of tank waste residuals. Laboratory studies with sediments so collected have shown that ion exchange, precipitation and dissolution, and surface complexation reactions have occurred between the tank wastes and subsurface sediments, moderating their chemical character and retarding the migration of select contaminants. Processes suspected to facilitate the far-field migration of immobile radionuclides including stable aqueous complex formation and mobile colloids were found to be potentially operative but unlikely to occur in the field, with the exception of cyanide-facilitated migration of 60Co. Certain fission product oxyanions (Mo, Ru, Se, Tc) and nitrates are the most mobile of tank waste constituents because their adsorption is suppressed by large concentrations of waste anions, the vadose zone clay fraction is negative in surface charge, and, unlike Cr, their reduced forms are unstable in oxidizing environments. Reaction/process-based transport modeling is beginning to be used for predictions of future contaminant mobility and plume evolution.

Because of their cross-cutting relationship with the surrounding matrix, they have been proposed as potential fast paths from former contaminant discharge sites at the surface to the water table. However, little was known of the detailed hydrogeologic properties of the dikes, and detailed modeling of flow and transport through the dikes had not been performed. We excavated a 2-m-wide clastic dike at the Hanford Site and characterized it using an air minipermeameter, infrared imagery, and grain size analyses. Field injection experiments were also used to characterize the system. The resulting data were used to prepare a detailed numerical model of the clastic dike and surrounding matrix for a portion of the excavation. Unsaturated flow through the system was modeled for several recharge rates. The highly heterogeneous nature of the system led to complex behavior, with the relative flux rates in the matrix and clastic dike being highly dependent on the recharge rates that were imposed on the system. The occurrence of saturation-dependent complementary flow networks suggests that the contaminant release history may be important to the choice of remedial actions. Contaminants released under high flux conditions could be inaccessible under low fluxes, and vice versa. This phenomenon may also help explain the occurrence of complex breakthrough patterns of contaminants at compliance planes.

The assessment followed the Resource Conservation and Recovery Act (RCRA) Corrective Action process to address the impacts of past tank waste releases to the vadose zone at the single-shell tank farm. Numerical models were developed that consider the extent of contamination presently within the vadose zone and predict contaminant movement through the vadose zone to groundwater. The transport of representative mobile (technetium-99) and immobile (cesium-137) constituents was evaluated in modeling. The model considered the accelerated movement of moisture around and beneath single-shell tanks that is attributed to bare, gravel surfaces resulting from the construction of the underground storage tanks. Infiltration, possibly nearing 100 mm yr (super -1) , is further amplified in the tank farm because of the umbrella effect created by percolating moisture being diverted by the impermeable, sloping surface of the large, 24-m-diameter, buried tank domes. For both the base case (no-action alternative) simulation and a simulation that considered placement of an interim surface barrier to minimize infiltration, predicted groundwater concentrations for technetium-99 at the SX tank farm boundary were exceedingly high, on the order of 106 pCi L (super -1) . The predicted concentrations are, however, somewhat conservative because of our use of two-dimensional modeling for a three-dimensional problem. A series of simulations were performed, using recharge rates of 50, 30, and 10 mm yr (super -1) , and compared to the base case (100 mm yr (super -1) ) results. As expected, lowering meteoric recharge delayed peak arrival times and reduced peak concentrations at the tank farm boundary.

For the experimental evaluation, a series of laboratory column tests were conducted in which Hanford formation sediment from the USDOE Hanford Site in Richland, WA, was first treated with a diluted hydrogen sulfide gas mixture to reduce sediment iron oxide to ferrous sulfide. Water containing dissolved oxygen was then pumped through the columns at different flow rates to determine the reoxidation rate and the reductive capacity of the treated sediment. The results indicated that the treated sediment has a significant reductive capacity consistent with the basic reactions associated with the treatment and reoxidation processes. The observed reductive capacity was found to be dependent on the flow rate of water during the reoxidation phase of the tests. The reductive capacity approached the maximum value predicted on the basis of the treatment reaction as the flow rate was decreased. Thus, laboratory treatment tests provide a means for predicting the reductive capacity of the barrier under field conditions. In the theoretical assessment, oxygen diffusion was identified as the dominant mechanism leading to reoxidation of the barrier. Depending on vadose zone characteristics, the predicted barrier lifetime varies from several years to more than 100 years.

Sediment core samples recovered from the borehole were subjected to distilled water and acid leaching procedures with the resulting leachates analyzed for isotopic and chemical signatures. Inductively coupled plasma-mass spectrometry (ICP-MS) techniques were used for determination of isotopic ratios for Cs, and Mo. Analysis of the isotopic patterns of Mo, combined with associated chemical data, showed evidence for at least two separate intrusions of nuclear waste into the subsurface. Isotopic data for Cs was inconclusive with respect to a source attribution signature.

We extend this concept to unsaturated porous media with two or three immiscible fluids. Mathematical expressions to describe the conductivity of each fluid in anisotropic porous media under unsaturated condition are derived in the form of symmetric second order tensors. The theory is applicable to the generalized hydraulic conductivity model and compatible types of saturation-pressure formulation. The extended model shows that the anisotropic coefficient of any one of the fluids is independent of the saturation of other fluids. Synthetic Miller-similar soils generated to be anisotropic were defined by allowing the saturated hydraulic conductivity to have different correlation ranges for different directions of flow. The extended TCT concept was tested using synthetic soils with four levels of heterogeneity and four levels of anisotropy. Numerical experiments of infiltration of two liquid phases, water and the nonaqueous phase liquid (NAPL) carbon tetrachloride, were performed to test the extended model. The results show that, similar to water in a two-fluid (air-water) system, NAPL retention curves in a three-fluid (air-NAPL-water) system were independent of flow direction but dependent on soil heterogeneity, whereas the connectivity-tortuosity coefficients are functions of both soil heterogeneity and anisotropy. The extended TCT model accurately describes unsaturated hydraulic functions of anisotropic soils and can be combined into commonly used relative permeability functions for use in multifluid flow and transport numerical simulations.

Our ability to understand the significance of these processes over time requires an accurate conceptual model that incorporates the various mechanisms of coupled chemical and physical processes. Adsorption, desorption, ion exchange, precipitation, dissolution, growth, solid solution, redox, microbial activity, and other processes are often incorporated into reactive transport models for the prediction of contaminant fate and transport. U.S. federal agencies use such models to evaluate contaminant transport and provide guidance to decision makers and regulators for treatment issues. We provide summaries of selected research projects and programs to demonstrate the level of activity in various applications and to present examples of recent advances in subsurface reactive transport modeling.

Historically, the geologic framework has been represented by simple homogeneous and horizontally stratified hydrogeologic units. However, as computer-processing capabilities have become more advanced, there has been more emphasis on improving spatial resolution and quantifying uncertainty in key model parameters. One of the more popular approaches has focused on geostatistical simulation of the flow-and-transport properties themselves, with little regard to the geologic strata and sedimentary sequences. Newer approaches are focusing more on geostatistical simulation of the sequence-stratigraphic relations of lithofacies and the geostatistical distributions of flow-and-transport properties within those facies. These approaches require more rigorous quantitative treatment of geologic data than is normally supported by the mostly qualitative nature of borehole geologic information. At the USDOE Hanford Site, efforts are being made to standardize borehole geologic data so they can be used in a systematic and quantitative way to define the spatial distribution of flow-and-transport properties in support of vadose zone flow-and-transport simulations. New detailed procedures translate qualitative descriptive information into categorical data and inconsistent quantitative and semiquantitative data into common parametric data sets. A geologic data-management system is being developed to manage and integrate these standardized categorical data sets with other existing databases to support synergistic analysis and to improve numerical representation of the hydrogeologic architecture.

The vadose zone here is characterized by often highly stratified glacial-fluvial sediments that give rise to complex subsurface-flow paths that contribute to uncertainty of contaminant fate and transport. Research efforts have focused on answering questions of contaminant transport from the viewpoint of geologic, biologic, geochemical, and hydrologic controls. This special section highlights key research topics concerning vadose zone problems at the Hanford Site. Research indicates that some of the contaminant species ( (super 137) Cs, (super 60) Co, (super 90) Sr) are retained by Hanford sediments as a result of geochemical reactions, rendering them effectively immobile except under extremely saline or acidic conditions, while other species ( (super 99) Tc, (super 129) I, (super 3) H) are typically mobile and have moved deep into the vadose zone and subsequently into groundwater. In addition, large quantities of organics, including carbon tetrachloride, have moved in complex ways as both vapor and liquid in the subsurface. Observed transport of mobile species is linked to liquid discharges and to elevated recharge rates that occur primarily at waste sites where land surfaces are void of vegetation and where winter rains have subsequently penetrated the subsurface wastes. A series of papers in this issue documents progress to date in understanding transport rates at Hanford, why anisotropy strongly affects the distribution of subsurface contaminants, why organic contaminants are difficult to find in the deep vadose zone, and what the impacts of hypersaline fluids are on waste form degradation and subsequent transport.

In oxidizing environments, in which the uranyl (UO (sub 2) (super 2+) ) ionic species is typically mobile, formation of sparingly soluble uranyl phosphate minerals exerts a strong influence on uranium transport. Autunite group minerals, X (sub 3-n) (super (n)+) [(UO (sub 2) ) (PO (sub 4) )] (sub 2) .xH (sub 2) O, have been identified as the long-term uranium-controlling phases in many systems of geochemical interest. Anthropogenic operations related to uranium mining operations have created acidic environments exposing uranyl phosphate minerals to low-pH groundwaters. Investigations regarding the dissolution behavior of autunite group minerals under acidic conditions have not been reported; consequently, knowledge of the longevity of uranium-controlling solids is incomplete. The purpose of this investigation was threefold: (1) to quantify the dissolution kinetics of natural calcium meta-autunite, Ca[(UO (sub 2) ) (sub 2) (PO (sub 4) ) (sub 2) ].3H (sub 2) O, and synthetic sodium meta-autunite, Na (sub 2) [(UO (sub 2) ) (sub 2) (PO (sub 4) ) (sub 2) ].3H (sub 2) O, under acidic conditions; (2) to measure the effect of temperature and pH on meta-autunite mineral dissolution; and (3) to investigate the formation of secondary uranyl phosphate phases as long-term controls on uranium migration. Single-pass flow-through (SPFT) dissolution tests were conducted over the pH range of 2 to 5 and from 5 degrees to 70 degrees C. Results presented here illustrate meta-autunite dissolution kinetics are strongly dependent on pH but are relatively insensitive to temperature variations. In addition, the formation of secondary uranyl-phosphate phases such as uranyl phosphate, (UO (sub 2) ) (sub 3) (PO (sub 4) ) (sub 2) .xH (sub 2) O, may serve as a secondary phase limiting the migration of uranium in the environment.

Even an EDTA-degrading bacterium, BNC1, does not degrade stable metal-EDTA complexes. In the present study, an ABC-type transporter was identified for possible uptake of EDTA because the transporter genes and the EDTA monooxygenase gene were expressed from a single operon in BNC1. The ABC-type transporter had a periplasmic-binding protein (EppA) that should confer the substrate specificity for the transporter; therefore, EppA was produced in Escherichia coli, purified, and characterized. EppA was shown to bind free EDTA with a dissociation constant as low as 25 nM by using isothermal titration calorimetry. When unstable metal-EDTA complexes, e.g., (Mg-EDTA) super(2-), were added to the EppA solution, binding was also observed. However, experimental data and theoretical analysis supported EppA binding only of free EDTA. When stable metal-EDTA complexes, e.g., (Cu-EDTA) super(2-), were titrated into the EppA solution, no binding was observed. Since EDTA monooxygenase in the cytoplasm uses some of the stable metal-EDTA complexes as substrates, we suggest that the lack of EppA binding and EDTA uptake are responsible for the failure of BNC1 cells to degrade the stable complexes.

The study results indicate that radionuclide concentrations in the Pripyat and Dnieper rivers were well above the drinking water limits immediately after the Chernobyl accident but have decreased significantly in subsequent years due to flushing, burying, and decaying. Because high concentrations of super(90)Sr and super(137)Cs, the major radionuclides affecting human health through the aquatic pathways, are associated with flooding, two earthen dikes were constructed along the Pripyat River. The left-bank dike alone was successful in reducing the super(90)Sr concentration in the river by half. The 100-m-high, movable New Safe Confinement (NSC), which will dover the current Chernobyl Shelter, will reduce radionuclide contamination further in these rivers and nearby groundwater. If the Chernobyl Shelter should collapse before the NSC is built, the resulting peak radionuclide concentrations in the Dnieper River are expected to still remain below the drinking water limits. The radionuclide influx to groundwater through the NSC should not have any effect on concentrations in the Pripyat River.

This assumption significantly enhances the modeled SOA yields as additional organic mass is made available to absorb greater amounts of oxidized secondary organic gases than otherwise. We investigate the applicability of this critical assumption by measuring SOA yields from ozonolysis of alpha -pinene (a major biogenic SOA precursor) in a smog chamber in the absence and in the presence of dioctyl phthalate (DOP) and lubricating oil seed aerosol. These particles serve as surrogates for urban hydrophobic POA. The results show that these POA did not enhance the SOA yields. If these results are found to apply to other biogenic SOA precursors, then the semi-empirical models used in many global models would predict significantly less biogenic SOA mass and display reduced sensitivity to anthropogenic POA emissions than previously thought.

We have investigated the importance of proteins adsorbed onto the surface of two distinct classes of nanomaterials (single-walled carbon nanotubes [SWCNTs]; 10-nm amorphous silica) in guiding nanomaterial uptake or toxicity in the RAW 264.7 macrophage-like model. Albumin was identified as the major fetal bovine or human serum/plasma protein adsorbed onto SWCNTs, while a distinct protein adsorption profile was observed when plasma from the Nagase analbuminemic rat was used. Damaged or structurally altered albumin is rapidly cleared from systemic circulation by scavenger receptors. We observed that SWCNTs inhibited the induction of cyclooxygenase-2 (Cox-2) by lipopolysaccharide (LPS; 1 ng/ml, 6 h) and this anti-inflammatory response was inhibited by fucoidan (scavenger receptor antagonist). Fucoidan also reduced the uptake of fluorescent SWCNTs (Alexa sub(647)). Precoating SWCNTs with a nonionic surfactant (Pluronic F127) inhibited albumin adsorption and anti-inflammatory properties. Albumin-coated SWCNTs reduced LPS-mediated Cox-2 induction under serum-free conditions. SWCNTs did not reduce binding of LPS sub(Alexa488) to RAW 264.7 cells. The profile of proteins adsorbed onto amorphous silica particles (50-1000 nm) was qualitatively different, relative to SWCNTs, and precoating amorphous silica with Pluronic F127 dramatically reduced the adsorption of serum proteins and toxicity. Collectively, these observations suggest an important role for adsorbed proteins in modulating the uptake and toxicity of SWCNTs and nano-sized amorphous silica.

In the course of remediation activities, large volumes of radioactive waste were generated and placed in temporary near-surface waste storage and disposal facilities. Trench and landfill type facilities were created from 1986-1987 in the Chernobyl Exclusion Zone at distances 0.5-15 km from the nuclear power plant site. This large number of facilities was established without proper design documentation, engineered barriers, or hydrogeological investigations and they do not meet contemporary waste-safety requirements. Immediately following the accident, a Shelter was constructed over the destroyed reactor; in addition to uncertainties in stability at the time of its construction, structural elements of the Shelter have degraded as a result of corrosion. The main potential hazard of the Shelter is a possible collapse of its top structures and release of radioactive dust into the environment. A New Safe Confinement (NSC) with a 100 y service life is planned to be built as a cover over the existing Shelter as a longer-term solution. The construction of the NSC will enable the dismantlement of the current Shelter, removal of highly radioactive, fuel-containing materials from Unit 4, and eventual decommissioning of the damaged reactor. More radioactive waste will be generated during NSC construction, possible Shelter dismantling, removal of fuel-containing materials, and decommissioning of Unit 4. The future development of the Exclusion Zone depends on the future strategy for converting Unit 4 into an ecologically safe system, i.e., the development of the NSC, the dismantlement of the current Shelter, removal of fuel-containing material, and eventual decommissioning of the accident site. To date, a broadly accepted strategy for radioactive waste management at the reactor site and in the Exclusion Zone, and especially for high level and long-lived waste, has not been developed.

LPA production in vivo is linked to platelet degranulation and the biological activities of this lipid are associated with wound healing. Osteoblasts and their progenitor cells are exposed to high levels of this lipid factor in regions adjacent to bone fractures and we postulate a role for LPA in skeletal healing. The regeneration of bone injuries requires a complex array of changes in gene expression, but the effects of LPA on mRNA levels in bone cells have not been investigated. We performed a genome-wide expression analysis in LPA-treated MC3T3-E1 pre-osteoblastic cells using Affymetrix GeneChip arrays. Cells exposed to LPA for 6 h exhibited 513 regulated genes, whereas changes in the levels of 54 transcripts were detected after a 24-h LPA treatment. Gene ontology analysis linked LPA-regulated gene products to biological processes that are known to govern bone healing, including cell proliferation, response to stress, organ development, chemotaxis /motility, and response to stimuli. Among the gene products most highly up-regulated by LPA were transcripts encoding the anti-inflammatory proteins sST2, ST2L, and heat-shock protein 25 (HSP25). RT-PCR analysis confirmed that these mRNAs were increased significantly in MC3T3-E1 cells and primary osteoblasts exposed to LPA. The response of cells to LPA is mediated by G-protein-coupled receptors, and the stimulation of anti-inflammatory gene expression in MC3T3-E1 cells was blocked by Ki16425, an inhibitor of LPA sub(1) and LPA sub(3) receptor forms. Pertussis toxin impaired only the LPA-induced expression of sST2. LPA-stimulated levels of sST2, ST2L and HSP25 mRNAs persisted if the cytosolic Ca super(2) super(+) elevations elicited by this lipid were blocked with BAPTA. In contrast to the stimulatory effect of LPA, exposure of MC3T3-E1 cells to fluid shear reduced the transcript levels of all three anti-inflammatory genes. The induction of sST2, ST2L and HSP25 expression by LPA suggests a role for this lipid factor in the regulation of osteoblastic cell function during periods of inflammation.

S. oneidensis MR-1 can reduce Mn(IV) and Fe(III) oxides and can produce current in microbial fuel cells. The mechanisms that are employed by S. oneidensis MR-1 to execute these processes have not yet been fully elucidated. Several different S. oneidensis MR-1 deletion mutants were generated and tested for current production and metal oxide reduction. The results showed that a few key cytochromes play a role in all of the processes but that their degrees of participation in each process are very different. Overall, these data suggest a very complex picture of electron transfer to solid and soluble substrates by S. oneidensis MR-1.

The 'Techa River Dosimetry System' (TRDS) was specifically elaborated for reconstruction of doses. A preliminary analysis of uncertainty for doses estimated using the current version of the TRDS showed large ranges in the uncertainty of internal absorbed dose and led to suggestions of methods to reduce uncertainties. The new methodological approaches described in this paper will allow for significant reduction of uncertainties of super(90)Sr-dose. The major sources of reduction are: making use of individual measured values of super(90)Sr and through development of a Household Registry to associate unmeasured persons with measured persons living in the same household(s).

2011-001607 AB - Electromagnetic borehole flowmeter (EBF) surveys are effective for accurately measuring the vertical groundwater-flow distribution in wells under ambient (static) and dynamic (e.g., pumping-induced) test conditions. Ambient EBF surveys are useful for determining the representativeness of well water samples for hydrochemical characterization, while dynamic EBF surveys are commonly used for determining the vertical distribution of relative hydraulic conductivity within the well-screen section. Monitoring wells with very low or no ambient vertical flow conditions are generally assumed to be more viable for the detection and monitoring of groundwater contaminants. To demonstrate this type of application, an EBF ambient survey was conducted at a well site used for monitoring a technetium-99 contaminant plume at the Hanford Site. The observed technetium-99 concentration for this well (41 pCi/L) is two to three orders-of-magnitude lower than observed concentrations at surrounding monitoring well facilities. An EBF ambient well survey conducted within the saturated well-screen interval at this well location indicated an upward, in-well vertical flow rate ranging up to 0.30 L/min. This observed upward flow supports a conceptual model where deeper relatively uncontaminated groundwater is flowing upward within the well and discharging to more shallow, overlying contaminated groundwater near the top of the well-screen section. Dynamic EBF surveys determine the lateral in-flow distribution within the well-screen section during pumping. From this lateral in-flow distribution, the vertical distribution of relative horizontal hydraulic conductivity within the surrounding aquifer can be inferred. This type of characterization information is important for the design and deployment of in situ treatment technologies within heterogeneous aquifer systems. At several treatability test sites, dynamic EBF vertical flow profiles have been used to evaluate formation heterogeneities and assess their potential impact on testing and deployment of the planned technology demonstrations. These data, along with other hydrogeologic characterization information, were used to develop a detailed site specific conceptual model of site hydrogeologic conditions.

Local populations of fall Chinook salmon were exposed to Hanford Site source groundwater that was diluted with Columbia River water. Specific endpoints included survival, development rate, and growth. Tissue burdens of fish were also measured to estimate uptake and elimination rates of chromium. Survival, development, and growth of early life stage fall Chinook salmon were not adversely affected by extended exposures (i.e., 98day) to hexavalent chromium ranging from 0.79 to 260kg/l. Survival for all treatment levels and controls exceeded 98% at termination of the test. In addition, there were no differences among the mean lengths and weights of fish among all treatment groups. Whole-body concentrations of chromium in early life stage fall Chinook salmon had a typical dose-response pattern; i.e., those subjected to highest exposure concentrations and longest exposure intervals had higher tissue concentrations. Given the spatial extent of chromium concentrations at the Hanford Site, and the dynamics of the groundwater-river water interface, the current cleanup criterion of 10kg/l chromium appear adequate to protect early life stage fall Chinook salmon. These findings, together with previous research indicate low risk to these populations.

Potentiometric titrations of millimolal palladium(II) solutions were used to monitor hydrolysis reactions of the mononuclear PdCl (sub 3) OH (super 2-) and PdCl (sub 2) OH (sub 2) (super 2-) species. Spectrophotometric titrations were also used to corroborate the speciation change and to extract the correlative molar absorption coefficients for the PdCl (sub 3) OH (super 2-) species in the 210-320 nm range. Longer-term potentiometric titrations systematically yielded precipitates which matured over a period of 6 weeks and resulted in a more extensive release of protons to the solution. Precipitation experiments in the 3-11 pH range showed the dominant precipitating phase to be Pd(OH) (sub 1.72) Cl (sub 0.28) . EXAFS measurements yielded an average of 3.50 O and 0.50 Cl atoms per Pd atom with a Pd-O distance of 2.012A and a Pd-Cl distance of 2.185A. Speciation modeling of proton and palladium mass balance data of experiments for palladium concentrations ranging from 0.047 to 10.0 m mol kg (super -1) required the presence of polynuclear complexes containing 3-9 palladium atoms. The existence of such complexes is moreover supported by previous investigations of palladium hydroxide chains of the type [Pd(OH) (sub 1.72) Cl (sub 0.28) ] (sub n) , that are coiled and/or aggregated into nanometer-sized (15-40 Aa) spheroids.

We hypothesized that relatively slow rates of U(VI) bioreduction would yield larger UO (sub 2) precipitates that would be more resistant to oxidation than those produced by rapid U(VI) bioreduction. We manipulated U(VI) bioreduction rates by varying the density of Shewanella putrefaciens CN32 added to U(VI) containing solutions with lactate as an electron donor. Characterization of biogenic UO (sub 2) particles by extended X-ray absorption fine-structure spectroscopy and transmission electron microscopy revealed that UO (sub 2) nanoparticles formed by relatively slow rates of U(VI) reduction were larger and more highly aggregated than those formed by relatively rapid U(VI) reduction. UO (sub 2) particles formed at various rates were incubated under a variety of abiotically and biologically oxidizing conditions. In all cases, UO (sub 2) that was formed by relatively slow U(VI) reduction was oxidized at a slower rate and to a lesser extent than UO (sub 2) formed by relatively rapid U(VI) bioreduction, suggesting that the stability of UO (sub 2) in situ may be enhanced by stimulation of relatively slow rates of U(VI) reduction.

What is the event source type (event identification)? If the event is an explosion, what is the yield? The answers to these questions involves processing seismometer waveforms with propagation paths predominately in the mantle. Four discriminants commonly used to identify teleseismic events are depth from travel time, presence of long-period surface energy (m (sub b) vs. M (sub S) ), depth from reflective phases, and polarity of first motion. The seismic theory for these discriminants is well established in the literature (see, for example, Blandford [1982] and Pomeroy et al. [1982]). However, the physical basis of each has not been formally integrated into probability models to account for statistical error and provide discriminant calculations appropriate, in general, for multidimensional event identification. This article develops a mathematical statistics formulation of these discriminants and offers a novel approach to multidimensional discrimination that is readily extensible to other discriminants. For each discriminant a probability model is formulated under a general null hypothesis of H (sub 0) : Explosion Characteristics. The veracity of the hypothesized model is measured with a p-value calculation (see Freedman et al. [1991] and Stuart et al. [1994]) that can be filtered to be approximately normally distributed and is in the range [0, 1]. A value near zero rejects H (sub 0) and a moderate to large value indicates consistency with H (sub 0) . The hypothesis test formulation ensures that seismic phenomenology is tied to the interpretation of the p-value. These p-values are then embedded into a multidiscriminant algorithm that is developed from regularized discrimination methods proposed by DiPillo (1976), Smidt and McDonald (1976), and Friedman (1989). Performance of the methods is demonstrated with 102 teleseismic events with magnitudes (m (sub b) ) ranging from 5 to 6.5. Example p-value calculations are given for two of these events.

The literature and conference proceedings are replete with approaches, templates, paradigms and such for treatment of uncertainty. However, these tools remain poorly used, especially those of the stochastic analytic sort, leading recently to explicit inquiries about why this is the case, in response to which entire journal issues have been dedicated. We recently reported on an informal small-scale survey of hydrogeology practitioners including scientists, engineers, academics and consultants, as the "marketplace" for techniques to deal with uncertainty. Preliminary results implied significant differences in perceived importance of uncertainty and in methods used to deal with it. Here we report on results of an expanded web-based casting of essentially the same survey, targeting a much larger international population of hydrogeology practitioners. The survey reports on quantitative and other methods for uncertainty characterization and analysis, frequency and level of usage, and reasons behind the selection or avoidance of available methods. Results shed light on fruitful directions for future research in uncertainty quantification in hydrogeology.

Laboratory studies indicate that supercritical CO2 can be injected into these formations and stored over very long timeframes through dissolution, hydrodynamic trapping, and mineralization. The first field validation test of safe and permanent containment of CO2 within these reactive mafic volcanic rocks is being undertaken in eastern Washington as part of the Big Sky Regional Carbon Sequestration Partnership. The focus of the basalt characterization test is an assessment of the mineralogical, geochemical, and hydrologic impact of injecting 1,000 to 3,000 tons of CO2 within a selected basalt reservoir zone. Specific technical objectives of the test are to: 1) assess the local/large-scale reservoir and adjacent formation responses to injection of supercritical CO2 into deep basalt formations, 2) track migration and evaluate containment of the CO2 for comparison with reservoir modeling predictions, and 3) evaluate the rate of CO2 mineralization for comparison with laboratory-derived predictions. Because basalts pose some of the greatest technical challenges for geophysical-based characterization and monitoring, an aggressive 2D surface seismic program is being accompanied by down-hole vertical seismic profiling (VSP), cross-well seismic tomography, micro-seismic monitoring, wireline logging, geochemical sampling, and detailed hydrologic testing programs. In this presentation we describe the design and acquisition of the surface seismic survey and the integration of geophysical and geologic technologies being employed to characterize the basalts and to track the movement of the plume and the geochemical changes in the basalts.

The transformation involves conversion of surface Fe(III) to Fe(II) by electron transfer from adsorbed reductant molecules followed by Fe(II) solubilization and precipitation of new phases. In the absence of direct scrutiny, single site models of this dissolution process have prevailed. Some Fe(III)-oxides such as hematite are semiconductors with a propensity for fast charge redistribution and limited electron diffusion by solid-state electron transport. Microscopic evidence suggests that sites of Fe(II) release are coupled to a process of mobile charge segregation through the surface to specific crystallographic regions. At room temperature charge carrier mobility depends on the diffusion of small polarons occurring by Fe(II/III) valence interchange. Molecular dynamics simulations and ab initio calculations predict high rates of small polaron hopping in the hematite bulk and at (001) and (012) surfaces in vacuum and in equilibrium with an overlying bulk water phase. The collective results suggest surface-specific Fe(II/III) valence cycling via oxidative Fe(II) adsorption and solid-state electron migration as a mechanism for oxide transformation. X-ray reflectivity measurements of Fe(II) interaction with hematite (001) show growth of an Fe(III) surface phase, confirming this view. The emerging picture for iron oxide transformation is one of multiple aproximal site communication by electron transport. This model has important implications for our understanding of chemical behavior at oxide-water interfaces, and therefore also the chemistry of soils and sediments. The case is an exemplary one justifying sustained research on the complexity and dynamics of mineral-water interfaces using advanced analytical probes combined with theory.

Such processes affect contaminant fate and transport, biogeochemical element cycling, ore deposit formation, biomineralization, and nuclear waste disposal. The ability to predict and quantify these and other important processes in nature requires a fundamental understanding of the structure of mineral-water interfaces and the reactions that occur here. I will present highlights from my recent experimental work that show that the accepted model of how arsenate adsorbs to minerals may be incorrect and that reveal the dynamic behavior of an iron oxide mineral surface that may occur during biogeochemical iron cycling. I will conclude with a list of my predictions, some realistic and some far-fetched, of the discoveries we may make in the next 50 years concerning interfacial adsorption and redox reactions, and the effect these discoveries may have on how humans interact with the environment.

It remains to be determined, however, whether these cytochromes are required for the growth of cells when a naturally-occurring crystalline iron oxide such as specular hematite (fNFe2O3) serves as terminal electron acceptor (TEA) for respiration. Strains of MR-1 were constructed with mutations in the genes encoding these cytochromes and their ability to grow with specular hematite as TEA was determined by epifluorescence microscopy in a flow-through reactor under anaerobic conditions. MtrC was required for the establishment of a specific interaction between the cell and hematite surface that enabled cells to subsequently reduce hematite. OmcA was required for maintenance of the interaction over extended periods of time. The difference in behavior of the mutants in the presence of natural specular hematite supported atomic force spectroscopic results of the interactions between purified preparations of recombinant forms of the cytochromes and synthetic hematite that suggest different roles for these cytochromes in mediating the interaction between cells of MR-1 and the hematite surface.

At the Uranium Mill Tailings Site in Rifle, CO, field-scale experiments with acetate as the electron donor have stimulated metal reducing bacteria to effectively remove uranium [U(VI)] from groundwater. The shallow depth to groundwater (3-4 m), thin saturated zone ( approximately 2.5 m), and well-defined groundwater flow system at the Rifle site facilitated the monitoring of microbial and geochemical processes which led to two important findings: decreased U(VI) bioreduction after the transition from iron reduction to sulfate reduction, and continued U(VI) removal from groundwater after acetate amendment was terminated, with removal increasing during the following 18 months. The objective of the research planned for the Rifle site is to gain a comprehensive and mechanistic understanding of the microbial factors and associated geochemistry controlling uranium mobility so that DOE can confidently remediate uranium plumes as well as support long-term stewardship of uranium-contaminated sites. Four hypotheses that address knowledge gaps in the following areas will be tested: 1) geochemical and microbial controls on stimulated U(VI) bioreduction by iron-reducers, 2) U(VI) sorption under Fe-reducing conditions, 3) post-biostimulation U(VI) stability and removal, and 4) rates of natural bioreduction of U(VI). The approach targets new knowledge that can be translated into scientifically defensible flow and reactive transport process models of microbially mediated and abiotic reactions. Hypotheses will be tested with a focused set of field and lab experiments that use recently developed sciences of proteogenomics and stable isotope probing to track microbial metabolic status during acetate amendment. This information will be linked to changes in Fe redox status and sulfide minerals, with field-scale changes detected by non-invasive hydrogeophysics, including 3-D resistivity tomography. This linkage will enable optimization of controllable factors such as electron donor concentration and identification of nutrient limitations, which, if relieved, could further enhance bioremediation of redox-sensitive metals.

With RH and aerosol SSA being rather constant during that time period, we suggest that the increasing aerosol loading from emission of pollutants is responsible for the observed reduced GSR and increased diffuse radiation in cloud-free skies. Although pollutant emissions continue to increase after the 1980s, the increment of aerosol SSA since 1980s can partly explain the transition of GSR from a decreasing trend to no apparent trend around that time. Preliminary analysis is also provided on the potential role of RH in affecting the global and diffuse solar radiation reaching the earth surface.

In this study, multichromatographic methods coupled with Fourier transform ion cyclotron resonance mass spectrometry, combined with subcellular fractionation, was used to test the hypothesis that the photosynthetic membrane of R. sphaeroides 2.4.1 contains a significant number of heretofore unidentified proteins in addition to the integral membrane pigment-protein complexes, including light-harvesting complexes 1 and 2, the photochemical reaction center, and the cytochrome bc sub(1) complex described previously. Purified ICM vesicles are shown to be enriched in several abundant, newly identified membrane proteins, including a protein of unknown function (AffyChip designation RSP1760) and a possible alkane hydroxylase (RSP1467). When the genes encoding these proteins are mutated, specific photosynthetic phenotypes are noted, illustrating the potential new insights into solar energy utilization to be gained by this proteomic blueprint of the ICM. In addition, proteins necessary for other cellular functions, such as ATP synthesis, respiration, solute transport, protein translocation, and other physiological processes, were also identified to be in association with the ICM. This study is the first to provide a more global view of the protein composition of a photosynthetic membrane from any source. This protein blueprint also provides insights into potential mechanisms for the assembly of the pigment-protein complexes of the photosynthetic apparatus, the formation of the lipid bilayer that houses these integral membrane proteins, and the possible functional interactions of ICM proteins with activities that reside in domains outside this specialized bioenergetic membrane.

Field campaign measurements and modeling studies over the past twenty years have examined the local scale processes responsible for the evolution of these pollutants. However, the effect of these pollutants on air quality and climate downwind of Mexico City was not known. To address this issue, extensive meteorological, chemical, and particulate measurements were made during March 2006 over central Mexico and the Gulf of Mexico as part of the Megacity Initiative Local and Global Regional Observations (MILAGRO). MILAGRO was comprised of several complementary field campaigns including MCMA (supported by Mexican agencies, NSF, and DOE), MAX-Mex (supported by DOE), MIRAGE-Mex (supported by NSF), and INTEX-B (supported by NASA) that were conducted at different spatial scales ranging from local-scale measurements over the Mexico City basin to synoptic-scale measurements several hundred kilometers downwind. The impact, or "footprint", of Mexico City emissions on synoptic-scale trace gases and particulate distributions may be somewhat different since gas-aerosol partitioning processes and aerosol-radiation effects couple trace gas and particulate evolution. The "footprint" also varies from day to day as a result of the evolving meteorological conditions in the region. The downwind impact of Mexico City pollutants is investigated by combining MILAGRO measurements with a fully-coupled meteorology-chemistry-particulate model (WRF-chem) to examine the how particulate mass, composition, and size distribution evolves over several days downwind of Mexico City. Understanding the regional- to synoptic-scale impacts requires understanding local-scale processes that affect non-linear chemistry in the vicinity of urban primary emissions; therefore, nested domains are employed that consist of an outer grid encompassing all of Mexico with a grid spacing of 12 km and an inner grid that encompasses central Mexico with a grid spacing of 3 km. The performance of the model is evaluated with measurements obtained from surface, aircraft, and satellite instrument platforms. The contribution of anthropogenic emissions from Mexico City in relation to other sources, including anthropogenic emissions outside of Mexico City, as well as biogenic, biomass burning, and dust sources is examined. Other modeling studies that are currently being conducted to examine the impact of Mexico City on air quality and climate will also be described.

A stochastic weather generator is used to generate meteorological data with precipitation and air temperature both modeled for wet and dry periods. The meteorological forcing is used to estimate snow state and streamflow through a simplified hydrologic model developed at Pacific Northwest National Laboratory (PNNL). The model itself is calibrated on the historical data before running for the synthetically generated meteorological data. A number of climate scenarios based on precipitation and temperature are designed and are used to study the impact of those scenarios on the streamflow and snow pack volumes. The findings can have direct relevance for the operation and management of water resources in the Pacific Northwest.

The over-arching goal of the project is to develop a mechanistic understanding of bioreductive and abiotic processes that control uranium mobility targeting new knowledge that can be translated into scientifically defensible flow and reactive transport process models. The Rifle IFC will conduct a focused set of field and lab experiments that use recently developed sciences of proteogenomics and stable isotope probing to track microbial metabolic status during acetate amendment. This information will be linked to changes in Fe redox status and sulfide minerals, with field-scale changes detected by non-invasive hydrogeophysics, including 3-D resistivity tomography. A key goal of the project is to combine abiotic sorption processes under reducing conditions with biotic processes controlling U(VI) reduction. The initial field-scale experiment for the Rifle IFC was conducted during the summer of 2007 with the objectives of collecting simultaneous metagenomic and proteomic samples during acetate amendment and to assess the impact of intentionally decreasing electron donor concentration on the metabolic processes of iron reducers. The 2007 experiment replicated previous field experiments, producing dominance of Geobacter sp. in groundwater within 10 days after the start of acetate amendment. The experiment also confirmed the importance of heterogeneities in controlling the flux of electron donor and the impact of naturally reduced zones on the duration of Fe reduction.

The contribution of snowmelt to runoff varies widely across the region depending on geographic location, elevation, land cover, and local meteorological conditions. Rain-on- snow events are relatively common within the snow transition zone and have contributed to a number of large floods. Snotel sites provide information on precipitation and changes in snow water equivalent at higher elevations, however, ground-based observation are generally lacking in the transition zone. We utilize an approach that allows the hydrologic model to be updated with remotely sensed spatial snow properties and measured streamflow using an Ensemble Kalman-based data assimilation strategy that accounts for uncertainty in meteorology, model parameters, and the observations used for updating. Although designed for ensemble streamflow forecasting, in this application the model provides a process based method to integrate multiple data sets across various spatial and temporal scales, allowing a probabilistic assessment of the role of snowmelt in runoff production.

III. Physiological approaches accounting for background and tracer kinetics. AN - 68182592; 17710612 AB - Manganese (Mn), an essential metal nutrient, produces neurotoxicity in workers exposed chronically to high concentrations of Mn-containing dusts. Our long-term goal was to develop a physiologically based pharmacokinetic (PBPK) model to support health risk assessments for Mn. A PK model that accounts for Mn-tracer kinetics and steady-state tissue Mn in rats on normal diets (about 45 ppm Mn) is described. The focus on normal dietary intakes avoids inclusion of dose-dependent processes that maintain Mn homeostasis at higher dose rates. Data used for model development were obtained from published literature. The model represents six tissues: brain, respiratory tract, liver, kidneys, bone, and muscle. Each of these has a shallow tissue pool in rapid equilibration with blood and a deep tissue store, connected to the shallow pool by transfer rate constants. Intraperitoneal (i.p.) tracer Mn is absorbed into systemic blood and equilibrated with the shallow and deep pools of tissue Mn. The model was calibrated to match steady-state tissue concentrations and radiotracer kinetics following an i.p. dose of 54Mn. Successful simulations showed uptake of 0.8% of dietary Mn, and estimated tissue partition coefficients and transfer rate constants in the tissues. Inhalation tracer 54Mn studies could only be adequately modeled by assuming that deposited Mn was absorbed into deep tissue stores in the lung before becoming available to move via blood to other tissues. In summary, this present effort provides the basic structure of a multiroute PBPK model for Mn that should now be easily extended to include homeostatic control and inhalation exposures in order to support risk assessment calculations for Mn.

Among the most important processes was the dissolution of soil minerals and precipitation of stable secondary phases. The objective of this investigation was to study the release of Fe into the aqueous phase upon dissolution of Fe-bearing soil minerals, and the subsequent formation of Fe-rich precipitates. Batch reactors were used to conduct experiments at 50 degrees C using solutions similar in composition to the waste fluids. Results clearly showed that, similarly to Si and Al, Fe was released from the dissolution of soil minerals (most likely phyllosilicates such as biotite, smectite and chlorite). The extent of Fe release increased with base concentration and decreased with Al concentration in the contacting solution. The maximum apparent rate of Fe release (0.566X10 (super -13) mol m (super -2) s (super -1) ) was measured in the treatment with no Al and a concentration of 4.32 mol L (super -1) NaOH in the contact solution. Results from electron microscopy indicated that while Si and Al precipitated together to form feldspathoids in the groups of cancrinite and/or sodalite, Fe precipitation followed a different pathway leading to the formation of hematite and goethite. The newly formed Fe oxy-hydroxides may increase the sorption capacity of the sediments, promote surface mediated reactions such as precipitation and heterogeneous redox reactions, and affect the phase distribution of contaminants and radionuclides.

This configuration consists of a high-level waste (HLW) canister fitted with a rack that holds mini-canisters containing a Pu-bearing lanthanide borosilicate (LaBS) waste glass and/or titanate-based ceramic ( approximately 15% of the total canister volume). The remaining volume of the HLW canister is then filled with HLW glass ( approximately 85% of the total canister volume). A 6-a pressurized unsaturated flow (PUF) test was conducted to investigate waste form-waste form interactions that may occur when water penetrates the canisters and contacts the waste forms. The PUF column volumetric water content was observed to increase steadily during the test because of water accumulation associated with alteration phases formed on the surfaces of the glasses. Periodic excursions in effluent pH, electrical conductivity, and solution chemistry were monitored and correlated with the formation of a clay phase(s) during the test. Geochemical modeling, with the EQ3NR code, of select effluent solution samples suggests the dominant secondary reaction product for the surrogate HLW glass, SRL-202, is a smectite di-octahedral clay phase(s), possibly nontronite [Na (sub 0.33) Fe (sub 2) (AlSi) (sub 4) O (sub 10) (OH) (sub 2) .n(H (sub 2) O)] or beidellite [Na (sub 0.33) Al (sub 2.33) Si (sub 3.67) O (sub 10) (OH) (sub 2) ]. This clay phase was identified in scanning electron microscope (SEM) images as discrete spherical particles growing out of a hydrated gel layer on reacted SRL-202 glass. Alpha energy analysis (AEA) of aliquots of select effluent samples that were filtered through a 1.8nm filter suggest that approximately 80% of the total measurable Pu was in the form of a filterable particulate, in comparison to unfiltered aliquots of the same sample. These results suggest the filterable particles are >1.8nm but smaller than the 0.2mu m average diameter openings of the Ti porous plate situated at the base of the column. In this advection-dominated system, Pu appeared to be migrating principally as or in association with colloids after being released from the LaBS glass. Analyses of reacted LaBS glass particles with SEM with energy dispersive X-ray spectroscopy suggest that Pu may have segregated into a discrete disk-like phase, possibly PuO (sub 2) . Alteration products that contain the neutron absorber Gd have not been positively identified. Separation of the Pu and the neutron absorber Gd during glass dissolution and transport could be a criticality issue for the proposed repository. However, the translation and interpretation of these long-term PUF test results to actual disposed waste packages requires further analysis.

AN - 50153389; 2008-069510 AB - The Earth's shallow subsurface results from integrated biological, geochemical, and physical processes. Methods are sought to remotely assess these interactive processes, especially those catalysed by micro-organisms. Using saturated sand columns and the metal reducing bacterium Shewanella oneidensis MR-1, we show that electrically conductive appendages called bacterial nanowires are directly associated with electrical potentials. No significant electrical potentials were detectable in columns inoculated with mutant strains that produced non-conductive appendages. Scanning electron microscopy imaging revealed a network of nanowires linking cells-cells and cells to mineral surfaces, "hardwiring" the entire length of the column. We hypothesize that the nanowires serve as conduits for transfer of electrons from bacteria in the anaerobic part of the column to bacteria at the surface that have access to oxygen, akin to a biogeobattery. These results advance understanding of the mechanisms of electron transport in subsurface environments and of how microorganisms cycle geologic material and share energy.

Various advanced thermoelectric (TE) materials have properties that are inherently advantageous for particular TE energy recovery applications. Skutterudites, zero- and one-dimensional quantum-well materials, and thin-film superlattice materials are providing enhanced opportunities for advanced TE energy recovery in transportation and industrial processes. This work demonstrates (1) the potential for advanced thermoelectric systems in vehicle energy recovery and (2) the inherently complex interaction between thermal system performance and thermoelectric device optimization in energy recovery. Potential power generation at specific exhaust temperature levels and for various heat exchanger performance levels is presented showing the current design sensitivities using different TE material sets. Mathematical relationships inherently linking optimum TE design variables and the thermal systems design (i.e., heat exchangers and required mass flow rates) are also investigated and characterized.

A sampling of Murky Pot (61 degree C; pH 7.1) led to the isolation of a novel arsenic-metabolizing organism (YeAs) which produces an arsenic sulfide mineral known as {szligbeta}-realgar, a mineral that has not previously been observed as a product of bacterial arsenic metabolism. YeAs was grown on a freshwater medium and utilized a variety of organic substrates, particularly carbohydrates and organic acids. The temperature range for growth was 37 to 75 degree C (optimum, 55 degree C), and the pH range for growth was 6.0 to 8.0 (optimum, pH 7.0 to 7.5). No growth was observed when YeAs was grown under aerobic conditions. The doubling time when the organism was grown with yeast extract and As(V) was 0.71 h. Microscopic examination revealed Gram stain-indeterminate, non-spore-forming, nonmotile, rod-shaped cells, with dimensions ranging from 0.1 to 0.2 mu m wide by 3 to 10 mu m long. Arsenic sulfide mineralization of cell walls and extracellular arsenic sulfide particulate deposition were observed with electron microscopy and elemental analysis. 16S rRNA gene analysis placed YeAs in the family Clostridiaceae and indicated that the organism is most closely related to the Caloramator and Thermobrachium species. The G+C content was 35%. YeAs showed no detectable respiratory arsenate reductase but did display significant detoxification arsenate reductase activity. The phylogenetic, physiological, and morphological characteristics of YeAs demonstrate that it is an anaerobic, moderately thermophilic, arsenic-reducing bacterium. This organism and its associated metabolism could have major implications in the search for innovative methods for arsenic waste management and in the search for novel biogenic mineral signatures.

In contrast to scatter plots, which only show the pair-wise correlation of species, commonality in CPF figures shows both correlation and information on the source region of the species in question. In this study, we use over 50 hourly volatile organic compound (VOC) concentrations and surface wind observations to show that VOCs with similar CPF patterns likely have common transport pathways. This was established with the multivariate technique, which uses the hierarchical clustering analysis to define clusters of VOCs having similar CPF patterns. This method revealed that alkenes, and in particular those with geometric isomers such as cis-/trans-2-butene and cis-/trans-2-pentene, have similar CPF patterns and hence, a common area of origin. The alkane isomers often show CPF patterns among themselves, and similarly, aromatic compounds often show similar patterns. We also show how calculated trajectory information can be used in the PSCF analysis to produce a graphic picture that identifies specific geographic areas associated with a given VOC (or other pollutant). The use of these techniques in the chemically and meteorologically complex environment of Houston, Texas, suggests its further utility in other areas with relatively simpler conditions.

At the same time, the number of sequenced bacterial genomes is rising sharply, far outpacing our ability to validate the predicted genes, let alone annotate bacterial proteomes. In this study, we use tandem mass spectrometry (MS/MS) to annotate the proteome of Shewanella oneidensis MR-1, an important microbe for bioremediation. In particular, we provide the first comprehensive map of post-translational modifications in a bacterial genome, including a large number of chemical modifications, signal peptide cleavages, and cleavages of N-terminal methionine residues. We also detect multiple genes that were missed or assigned incorrect start positions by gene prediction programs, and suggest corrections to improve the gene annotation. This study demonstrates that complementing every genome sequencing project by an MS/MS project would significantly improve both genome and proteome annotations for a reasonable cost.

AN - 70673416; 17274063 AB - The effect of calcium on the dissolution and microbial reduction of a representative solid phase uranyl [U(VI)], sodium boltwoodite (NaUO(2)SiO(3)OH . 1.5H(2)O), was investigated to evaluate the rate-limiting step of microbial reduction of the solid phase U(VI). Microbial reduction experiments were performed in a culture of a dissimilatory metal-reducing bacterium (DMRB), Shewanella oneidensis strain MR-1, in a bicarbonate medium with lactate as electron donor at pH 6.8 buffered with PIPES. Calcium increased the rate of Na-boltwoodite dissolution and U(VI) bioavailability by increasing its solubility through the formation of a ternary aqueous calcium-uranyl-carbonate species. The ternary species, however, decreased the rates of microbial reduction of aqueous U(VI). Laser-induced fluorescence spectroscopy (LIFS) and transmission electron microscopy (TEM) collectively revealed that microbial reduction of solid phase U(VI) was a sequentially coupled process of Na-boltwoodite dissolution, U(VI) aqueous speciation, and microbial reduction of dissolved U(VI) to U(IV) that accumulated on bacterial surfaces/periplasm. Under studied experimental conditions, the overall rate of microbial reduction of solid phase U(VI) was limited by U(VI) dissolution reactions in solutions without calcium and limited by microbial reduction in solutions with calcium. Generally, the overall rate of microbial reduction of solid phase U(VI) was determined by the coupling of solid phase U(VI) dissolution, U(VI) aqueous speciation, and microbial reduction of dissolved U(VI) that were all affected by calcium.

AN - 68101985; 17499879 AB - Aquifer sediments collected via split-spoon sampling in two new groundwater wells in the 200-UP-1 operable unit at the Hanford Site were characterized and showed typical Ringold Unit E Formation properties dominated by gravel and sand. High iron-oxide content in Fe oxide/clay coatings caused the highest U(VI) adsorption as quantified by batch K(d) values, indicating iron oxides are the key solid adsorbent in the 200-UP-1 sediments that affect U(VI) fate and mobility. Even though U(VI) adsorption on the gravel-sized fraction of the sediments is considered to be negligible, careful characterization should be conducted to determine U(VI) adsorption on gravel, because of presence of Fe oxides coatings and diffusion-controlled adsorption into the gravel particles' interior surfaces. A linear adsorption isotherm was observed up to 10(-6) M (238 microg/L) of total U(VI) concentration in batch U(VI) adsorption tests with varying total U(VI) concentrations in spiked groundwater. U(VI) adsorption decreased with increasing concentrations of dissolved carbonate, because strong anionic aqueous uranium-carbonate complexes formed at high pH and high alkalinity conditions. Noticeable uranium desorption hysteresis was observed in a flow-through column experiment, suggesting that desorption K(d) values for aged uranium-contaminated sediments at the Hanford Site can be larger than adsorption K(d) values determined in short-term laboratory experiments and slow uranium release from contaminated sediments into the groundwater is expected.

As the bioavailable Fe(III) terminal electron acceptor was depleted in the zone just downgradient of the acetate injection gallery, sulfate-reducing organisms came to dominate the microbial community. In the present study, we use multicomponent reactive transport modeling to analyze data from the 2002 field experiment to identify the dominant transport and biological processes controlling uranium mobility during biostimulation, and determine field-scale parameters for these modeled processes. The coupled process simulation approach was able to establish a quantitative characterization of the principal flow, transport, and reaction processes based on the 2002 field experiment, that could be applied without modification to describe the 2003 field experiment. Insights gained from this analysis include field-scale estimates of the bioavailable Fe(III) mineral threshold for the onset of sulfate reduction, and rates for the Fe(III), U(VI), and sulfate terminal electron accepting processes.

AN - 70726359; 17572470 AB - Uniformly arrayed zirconium-phosphate nanoporous material was synthesized, characterized, and used as an adsorbent for removal of U(VI) in a NaNO3 solution with varying background conditions including pH, ionic strength, U(VI) concentrations, and carbonate concentrations. Batch U(VI) adsorption results showed that U(VI) adsorption reached steady-state condition within 48 h, and all the dissolved U(VI) (10(-6)M) was removed by this material at neutral pH and closed conditions to atmospheric CO2(g). The U(VI) adsorption followed a traditional Langmuir adsorption isotherm, and the distribution coefficient (K(d)) calculated from the linear region of the Langmuir isotherm was 105,000 mL g(-1). Because this phosphate-bearing nanoporous material exhibits high thermal stability and has a very high Kd value, it can be applied as an efficient adsorbent for removing U(VI) from various contaminated waste streams, such as those present at the US Department of Energy defense sites and the proposed geologic radioactive waste disposal facility at Yucca Mountain in Nevada.

AN - 70714281; 17630635 AB - Due to the ubiquitous nature of ionizing radiation, in vivo measurement systems designed to measure low levels of radionuclides in people are usually enclosed within a high-density shield. Lead, steel, earth, and water are just some of the materials that have been and are being used to shield the detectors from radiations of cosmic, atmospheric, man-made, and terrestrial origin. At many Department of Energy sites, the counting room shields are constructed of pre-World War II steel to reduce the background levels in order to perform measurements that have low minimum detectable activities. The pre-World War II steel is commonly called low background steel in the in vivo industry vernacular. The low background descriptor comes from the fact the steel was manufactured prior to the beginning of atmospheric testing of nuclear weapons in the 1940's. Consequently, the steel is not likely to be contaminated with fission or activation products from fallout. For high energy photons (600 keV < E < 1500 keV), 30 cm of steel shielding significantly reduces the measured background radiation levels. This is the story of the unique steel that began as the hull of the U.S.S. Indiana and now forms a shielded room at the In Vivo Radiobioassay and Research Facility in Richland, Washington.

AN - 70701507; 17622819 AB - Atmospheric dispersion computer programs are widely used to simulate air and surface exposures from airborne and deposited radionuclides. For longer-term emissions (i.e., occurring for a year or longer), many of these models use joint frequency tables, which summarize the frequency of occurrence of specific ranges of wind speed and direction as a function of stability categories to define the atmospheric dispersion conditions. This paper addresses directional limitations of a computer code, STAR (STability ARray), that has been historically used to generate these joint frequency tables. As part of an effort to provide an updated version of the STAR code, directional limitations were found stemming from the manner in which the reported direction data are stored in joint frequency data tables. The STAR code provides tabular frequency summaries based on sixteen 22.5-degree wind direction sectors. Surface observation data in the CD-144 format from the United States National Oceanographic and Oceanic Administration (NOAA) is read by the STAR program. For 1964 and later years the wind direction has been reported in CD-144 datasets as 10-degree increments instead of the 22.5-degree sector direction codes used in prior years. When 10-degree data are input, the process by which the STAR code puts each wind direction occurrence into the 22.5-degree sectors results in a consistent positive bias for cardinal direction sectors (north, south, east, and west), and a consistent negative bias for all the other sectors. Individual entries in the joint frequencies summaries with high wind frequencies tend to be overestimated by up to about 30% or underestimated down to about -10%. A larger range of changes is seen for entries with lower wind frequencies. To avoid these errors, it is recommended that joint frequencies generated by the STAR program be checked for this directional bias. If the NOAA observational data are for 1964 or later years and generated by the original EPA STAR program, it is likely that the bias will be in the dataset.

Various empirical approaches, such as the distribution coefficient and Freundlich and Langmuir isotherm equations, have been used to represent adsorption. The empirical approaches are not capable of accounting for the effects of variable chemical conditions, such as pH, on adsorption reactions. This can be done using chemical models such as surface complexation models. These models define specific surface species, chemical reactions, equilibrium constants, mass balances, and charge balances, and their molecular features can be given thermodynamic significance. Ion adsorption mechanisms and surface configurations for the surface complexation models can be established from independent experimental observations. These include both indirect measurements, such as point of zero charge shifts, ionic strength effects, and calorimetry, and direct spectroscopic techniques, including vibrational spectroscopy, nuclear magnetic resonance (NMR) spectroscopy, and X-ray absorption spectroscopy. Surface complexation models were developed for single mineral phases but have now been applied to natural mineral assemblages using both component additivity (CA) and generalized composite (GC) approaches. Surface complexation models have been incorporated into subsurface transport models at several field sites, although simplifying assumptions are needed to deal with heterogeneous materials. Surface complexation models for contaminant adsorption have the potential to increase the confidence and scientific credibility of transport modeling by reducing the uncertainty in quantifying retardation and providing a means of quantifying that uncertainty.

In a companion paper (Oostrom et al., 2006a), experiments related to aqueous dissolution and enhanced remediation were discussed. The experiments investigating flow behavior include infiltration and redistribution experiments with both light and dense NAPLs in homogeneous and heterogeneous porous medium systems. The techniques used for NAPL saturation mapping for intermediate-scale experiments include photon-attenuation methods such as gamma and X-ray techniques, and photographic methods such as the light reflection, light transmission, and multispectral image analysis techniques. Solute tracer methods used for detection and quantification of NAPL in the subsurface are primarily limited to variations of techniques comparing the behavior of conservative and partitioning tracers. Besides a discussion of the experimental efforts, recommendations for future research at this laboratory scale are provided.

When a migratory cell is stimulated with a chemoattractant or extracellular matrix (ECM) gradient, it responds with localized amplification of signals on the side facing the gradient. The signals mediate reorganization of the actin-myosin cytoskeleton, leading to morphological polarization of the cell and pseudopodium extension. To identify these signals, we developed an approach to biochemically isolate the pseudopodium from the cell body using 3.0-micrometer porous filters for large-scale quantitative proteomic and phosphoproteomic analysis. Here, we detail the methodology for pseudopodium purification and proteomic analysis. This model system should be widely applicable for the analysis of the pseudopodium proteome from various migratory cell lines, including primary and cancer cell lines stimulated with a diverse array of chemoattractants, ECM proteins, or both.

This article compares and evaluates two downscaled simulations for the United States made using the fifth-generation Pennsylvania State University-NCAR Mesoscale Model with the goal of understanding how errors in the downscaled climate simulations may introduce uncertainty in air quality assessment. The two downscaled simulations were driven by boundary conditions from the NCEP-NCAR global reanalysis and a global climate simulation generated by the Goddard Institute for Space Studies global circulation model, respectively. Comparisons of the model runs are made against the boundary layer and circulation characteristics of the North American Regional Reanalysis, and also against observed precipitation. The relative dependence of different simulated quantities on regional forcing, model parameterizations, and large-scale circulation provides a framework to understand similarities and differences between model simulations. Results show significant improvements in the downscaled diurnal wind patterns, in response to the complex orography, that are important for air quality assessment. Evaluation of downscaled boundary layer depth and winds, precipitation, and large-scale circulation shows larger biases related to model physics and biases in the GCM large-scale conditions. Based on the comparisons, recommendations are made to improve the utility of downscaled scenarios for air quality assessment.

The SVM methodology provides a statistically sound and robust approach to solving the inverse problem, and thus to building statistical models. EnKF is an extension of the Kalman Filter (KF), a well-known tool in prediction updating. In the present research, ground measurements were used to build a SVM-type soil moisture predictor. Subsequent observations and their statistics were assimilated to update predictions from the SVM model by coupling it with EnKF. In this way, both model predictions and ground data, as well as their statistics, are fused thus minimizing the prediction error and making the predictions and observations statistically consistent. The results are shown for two approaches; one in which update is done at every time step and the other which assumes that data is only available at alternate time steps (in window of 10 time steps) and hence update is performed at those occasions. The SVM-EnKF coupling is shown to improve soil moisture forecasts in an example using data from the Soil Climate Analysis Network site at Ames, Iowa.

The set of interatomic potentials employed is the same as used in many recent static and dynamic He-Fe simulations. Interstitial He atoms have a maximum positive binding energy of about 1 eV to the screw dislocation core relative to interstitial He atoms in the perfect crystal, which is about half that of binding energies of He to the edge dislocation. However, interstitial He atoms diffuse along the screw dislocation core with a migration energy of 0.4-0.5 eV, which is the same range as migration energies of interstitial He atoms along the edge dislocation.

It is shown that the Soderberg relation predicting no axial creep strains in biaxially-loaded tubes is correct for both plastic and creep strains. Swelling strains are shown to be isotropically distributed both for stress-free and stress-affected swelling, while precipitation strains are somewhat anisotropic in their distribution. When corrected for stress-enhancement of swelling, the derived irradiation creep strains appear to be identical for both annealed and 20% cold-worked specimens, and also for tubes strained by rise to power increases in pressure. For relatively small creep strains it is often difficult to separate the creep and non-creep components of deformation.

It is found in all cases that creep results from dislocation motion. But the mechanism changes with increasing temperature and lower stress from one controlled by the climb and interaction of individual dislocations, to one controlled by sub-grain boundary structure that is created by relaxation of the interacting dislocations to lower energy planar arrays. This change in mechanism corresponds to a change from power law creep to Newtonian creep such that the stress exponent drops from 4 to 1. Although it is possible to explain the Newtonian response as Nabarro-Herring or Coble creep, it appears more likely that behavior is due to Harper-Dorn creep, in which case the change in response occurs at the Peierls stress.

In our study, a continuous-fiber composite is simulated by four concentric cylinders to explore the magnitude of radial stresses when irradiation swelling of the various components is incorporated. The outputs of this model were input into a time-dependent crack-bridging model to predict crack growth rates in an environment where thermal and irradiation creep of SiC-based fibers is considered. Under assumed Coulomb friction the fiber-matrix sliding stress decreases with increasing dose and then increases once the pyrocarbon swelling reaches 'turn around'. This causes an initial increase in crack growth rate and higher stresses in crack bridging fibers at higher doses. An assumed irradiation creep law for fine-grained SiC fibers is shown to dominate the radiation response.

A number of tensile and fracture toughness specimens of prime aged CuCrZr alloy were given overaging treatments at 873 K for 1, 2 and 4 h. A subset of these specimens were irradiated with fission neutrons in the BR-2 reactor at Mol (Belgium) at 333 K and 573 K to a dose level of 0.3 dpa. Both unirradiated and irradiated tensile specimens were tested at 295 K, 333 K and 573 K. Fracture toughness tests were carried out at 293, 333 and 573 K. Transmission electron microscopy was used to investigate the effects of overaging, subsequent irradiation and the effect of deformation. The results indicate that the overaging treatment of 873 K for 1 h produced a precipitate microstructure that improved the plastic instability, overall ductility and fracture toughness.

The diffusion coefficient of a He interstitial and the effective migration energies were determined. The He atom diffuses along the capital sigma 11 grain boundary one-dimensionally along specific directions, while it migrates two-dimensionally at low temperatures, and three-dimensionally at higher temperatures, in the capital sigma 3 grain boundary. The di-He interstitial cluster can migrate rapidly along the capital sigma 3 interface at low temperatures, but not at the capital sigma 11 interface. It has been observed that a di-He interstitial cluster can kick out a self interstitial atom (SIA) at high temperatures, forming a He2V complex. The SIA migrates rapidly near interfaces, whereas the He2V complex is immobile at the temperatures considered. This small cluster may serve as the smallest nucleation for the formation of helium bubbles at interfaces.

We recently implemented an approach for producing controlled He-to-dpa ratios under neutron irradiation using a novel alpha -implantation technique. Thin 1-4 is a subset of m NiAl coatings were deposited on Eurofer-97 TEM discs to produce a uniform He deposition zone of 6-8 is a subset of m. The test matrix is aimed at characterizing the transport, fate and consequences of He and He-to-dpa ratio variation on alloys with a wide range of starting microstructure. We explore the effect He-to-dpa ratio and temperature on the microstructure of conventionally processed Eurofer-97. Bubbles were found at all irradiation temperatures, with estimated maximum diameters of 12, 6.9 and 1.4 nm at 500 DGC (9 dpa and 372 appm He), 400 DGC (3.9 dpa and 82 appm He) and 300 DGC (3.9 dpa and 89 appm He), respectively.

Sink strengths for one-dimensionally (1D) gliding interstitial loops undergoing occasional direction changes have been described analytically and confirmed by kinetic Monte Carlo (KMC) simulations. Here we report on KMC simulations investigating a different transition from 1D to 3D diffusion of 1D gliding loops for which their 1D migration is interrupted by occasional 2D migration due to conservative climb by dislocation core diffusion within a plane transverse to their 1D glide direction. Their transition from 1D to 3D kinetics is significantly different from that due to direction changes. The KMC results are compared to an analytical description of this diffusion mode in the form of a master curve relating the 1D normalized sink strength to the frequency of disturbance of 1D migration.

To understand the processes at molecular level, in this study, a whole-genome oligonucleotide microarray was used to examine differential expression patterns between planktonic populations and mature biofilm of Desulfovibrio vulgaris on a steel surface. Statistical analysis revealed that 472 genes were differentially expressed (1.5-fold or more with a q value less than 0.025) by comparing the biofilm cells with the planktonic cells. Among the differentially expressed genes were several that corresponded to genes identified in many aerobic bacterial biofilms (i.e., Pseudomonas species and Escherichia coli) such as genes encoding flagellin, a flagellar motor switch protein, chemotaxis proteins involved in cell motility, as well as genes involved in exopolysaccharide biosynthesis. In addition, the biofilm-bound cells of D. vulgaris exhibited decreased transcription of genes involved in protein synthesis, energy metabolism and sulfate reduction, as well as genes involved in general stress responses. These findings were all consistent with early suggestion that the average physiology of the biofilm cells were similar to cells reduced in growth. Most notably, up-regulation of large number of outer membrane proteins was observed in the D. vulgaris biofilm. Although their function is still unknown, the higher expression of these genes in the biofilm could implicate important roles in the formation and maintenance of multi-cellular consortium on a steel surface. The study provided insights into the metabolic networks associated with the formation and maintenance of a D. vulgaris biofilm on a steel surface.

The aim was to evaluate links between molecular changes and higher level outcomes after exposure to endocrine-active chemicals (EACs) with different modes of action. To aid our analysis and interpretation of EAC-related effects, we first examined variation in the relative abundance of steroidogenesis-related gene transcripts in the gonads of male and female fathead minnows as a function of age, gonad development, and spawning status, independent of EAC exposure. Gonadal expression of several genes varied with age and/or gonadal somatic index in either males or females. However, with the exception of aromatase, steroidogenesis-related gene expression did not vary with spawning status. Following the baseline experiments, expression of the selected genes in male fathead minnows exposed to KTC or VZ was evaluated in the context of effects observed at higher levels of organization. Exposure to KTC elicited changes in gene transcription that were consistent with an apparent compensatory response to the chemical's anticipated direct inhibition of steroidogenic enzyme activity. Exposure to VZ, an antiandrogen expected to indirectly impact steroidogenesis, increased pituitary expression of follicle-stimulating hormone {szligbeta}-subunit as well as testis expression of 20{szligbeta}-hydroxysteroid dehydrogenase and luteinizing hormone receptor transcripts. Results of this study contribute to ongoing research aimed at understanding responses of the teleost hypothalamic-pituitary-gonadal axis to different types of EACs and how changes in molecular endpoints translate into apical outcomes reflective of either adverse effect or compensation.

AN - 70726596; 17590257 AB - Chlorpyrifos (CPF) is a commonly used diethylphosphorothionate organophosphorus (OP) insecticide. Diethylphosphate (DEP), diethylthiophosphate (DETP) and 3,5,6-trichloro-2-pyridinol (TCPy) are products of metabolism and of environmental degradation of CPF and are routinely measured in urine as biomarkers of exposure. However, because these same chemicals can result from metabolism or by biodegradation, monitoring total urinary metabolite levels may be reflective of not only an individual's contact with the parent pesticide, but also exposure with the metabolites, which are present in the environment. The objective of the current study was to compare the pharmacokinetics of orally administered DEP, DETP and TCPy with their kinetics following oral dosing with the parent insecticide CPF in the rat. Groups of rats were orally administered CPF, DEP, TCPy or DETP at doses of 140mumol/kg body weight, and the time-courses of the metabolites were evaluated in blood and urine. Following oral administration, all three metabolites were well absorbed with peak blood concentrations being attained between 1 and 3h post-dosing. In the case of DEP and TCPy virtually all the administered dose was recovered in the urine by 72h post-dosing, suggesting negligible, if any, metabolism; whereas with DETP, approximately 50% of the orally administered dose was recovered in the urine. The CPF oral dose was likewise rapidly absorbed and metabolized to DEP, TCPy and DETP, with the distribution of metabolites in the urine followed the order: TCPy (22+/-3mumol)>DETP (14+/-2mumol)>DEP (1.4+/-0.7mumol). Based upon the total amount of TCPy detected in the urine a minimum of 63% of the oral CPF dose was absorbed. These studies support the hypotheses that DEP, DETP and TCPy present in the environment can be readily absorbed and eliminated in the urine of rats and potentially humans.

AN - 68187922; 17711232 AB - We have shown that superparamagnetic iron oxide (Fe3O4) nanoparticles with a surface functionalization of dimercaptosuccinic acid (DMSA) are an effective sorbent material for toxic soft metals such as Hg, Ag, Pb, Cd, and Tl, which effectively bind to the DMSA ligands and for As, which binds to the iron oxide lattices. The nanoparticles are highly dispersible and stable in solutions, have a large surface area (114 m2/g), and have a high functional group content (1.8 mmol thiols/g). They are attracted to a magnetic field and can be separated from solution within a minute with a 1.2 T magnet. The chemical affinity, capacity, kinetics, and stability of the magnetic nanoparticles were compared to those of conventional resin based sorbents (GT-73), activated carbon, and nanoporous silica (SAMMS) of similar surface chemistries in river water, groundwater, seawater, and human blood and plasma. DMSA-Fe3O4 had a capacity of 227 mg of Hg/g, a 30-fold larger value than GT-73. The nanoparticles removed 99 wt% of 1 mg/L Pb within a minute, while it took over 10 and 120 min for Chelex-100 and GT-73 to remove 96% of Pb.

For andalusite, seven peaks were observed when the electric vector, E, is parallel to [100]: four intense ones at 3,440, 3,460, 3,526, and 3,597 cm (super -1) and three weaker ones at 3,480, 3,520, and 3,653 cm (super -1) . Six peaks, three intense ones at 3,440, 3,460, and 3,526 cm (super -1) and three weaker ones at 3,480, 3,520, and 3,653 cm (super -1 ) when E parallels [010]. No peaks were observed when E is parallel to [001]. The concentration of water in andalusite varies between 110 and 168 ppm wt% H (sub 2) O. Polarized FTIR spectra indicate that the OH vector is parallel to (001) in andalusite and sillimanite and (111[bar]) in kyanite. Examination of the L(r) (3, -3) critical points in comparison with the polarized FTIR indicates that H prefers to bond to the oxygen atoms O1 and O2 in andalusite and O2 and O4 in sillimanite, corresponding to the underbonded oxygen atoms and those with the largest L(r) maxima. In kyanite, comparison of the FTIR spectrum and the critical points indicates that H will preferentially bond to the two 4 co-ordinated O2 and O6 atoms.

To overcome this problem, we have used a high-throughput peptide screen to identify an alternate binding motif (i.e., CCKACC or KA tag), which has a similar brightness to the classical sequence upon MAP binding, but displays altered rates and affinities of association that permit the differential labeling of these peptide sequences by the red probe 4,5-bis(1,3,2-dithiarsolan-2-yl)-resorufin (ReAsH-EDT sub(2)) or its green cognate 4',5'-bis(1,3,2-dithoarsolan-2-yl)fiuorescein (FLAsH-EDT sub(2)). The utility of this labeling strategy was demonstrated following the expression of PG- and KA-tagged subunits of RNA polymerase in E. coli. Specific labeling of two subunits of RNA polymerase in cellular lysates was achieved, whereby ReAsH-EDT sub(2) is shown to selectively label the PG-tag on RNA polymerase alpha -subunit prior to the labeling of the KA-tag sequence of the beta -subunit of RNA polymerase with FlAsH-EDT sub(2). These results demonstrate the ability to selectively label multiple individual proteins with orthogonal sequence tags in complex cellular lystates with spectroscopically distinct MAPs, and indicate the absolute specificity of ReAsH to target expressed proteins with essentially no nonspecific binding interactions.

The Gibbs Centroid Sampler reports a centroid alignment, i.e. an alignment that has the minimum total distance to the set of samples chosen from the a posteriori probability distribution of transcription factor binding-site alignments. In so doing, it garners information from the full ensemble of solutions, rather than only the single most probable point that is the target of many motif-finding algorithms, including its predecessor, the Gibbs Recursive Sampler. Centroid estimators have been shown to yield substantial improvements, in both sensitivity and positive predictive values, to the prediction of RNA secondary structure and motif finding. The Gibbs Centroid Sampler, along with interactive tutorials, an online user manual, and information on downloading the software, is available at: http://bayesweb.wadsworth.org/gibbs/gibbs.html.

Closely related organisms are most likely to have common regulatory motifs; however, the recent speciation of such organisms results in the high degree of correlation in their genome sequences, confounding the detection of functional elements. Additionally, alignment algorithms that use optimization techniques are limited to the detection of a single alignment that may not be representative. Comparative-genomics studies must be able to address the phylogenetic correlation in the data and efficiently explore the alignment space, in order to make specific and biologically relevant predictions. RESULTS: We describe here a Gibbs sampler that employs a full phylogenetic model and reports an ensemble centroid solution. We describe regulatory motif detection using both simulated and real data, and demonstrate that this approach achieves improved specificity, sensitivity, and positive predictive value over non-phylogenetic algorithms, and over phylogenetic algorithms that report a maximum likelihood solution.

A prerequisite for this type of reaction would be the formation of a stable bond between a cytochrome and an iron oxide surface. Atomic force microscopy (AFM) was used to detect whether a specific bond forms between a hematite (Fe sub(2)O sub(3)) thin film, created with oxygen plasma-assisted molecular beam epitaxy, and recombinant MtrC or OmcA molecules coupled to gold substrates. Force spectra displayed a unique force signature indicative of a specific bond between each cytochrome and the hematite surface. The strength of the OmcA-hematite bond was approximately twice that of the MtrC-hematite bond, but direct binding to hematite was twice as favorable for MtrC. Reversible folding/unfolding reactions were observed for mechanically denatured MtrC molecules bound to hematite. The force measurements for the hematite-cytochrome pairs were compared to spectra collected for an iron oxide and S. oneidensis under anaerobic conditions. There is a strong correlation between the whole-cell and pure-protein force spectra, suggesting that the unique binding attributes of each cytochrome complement one another and allow both MtrC and OmcA to play a prominent role in the transfer of electrons to Fe(III) in minerals. Finally, by comparing the magnitudes of binding force for the whole-cell versus pure-protein data, we were able to estimate that a single bacterium of S. oneidensis (2 by 0.5 mu m) expresses similar to 10 super(4) cytochromes on its outer surface.

Effects of chemical modifications of nucleotides on the structure of DNA have been characterized through large scale density functional theory computations. Quantum mechanical structural optimizations of DNA fragments with three pairs of nucleotides and accompanying counteractions were performed with a B3LYP exchange-correlation functional and 6-31G(d,p) basis sets. The ''intact'' DNA fragment contained adenine in the middle layer, while the ''damaged'' fragment had the adenine replaced with 8-oxo-adenine. The electrostatic potential around these DNA fragments was projected on a cylindrical surface around the double helix. The two-dimensional maps of EP of the intact and damaged DNA fragments were analyzed to identify these modifications of EP that result from the occurrence of 8-oxo-adenine (8oA). It was found that distortions of a phosphate group neighboring 8oA and displacements of the accompanying countercation are clearly reflected in the EP maps.

In this study, we reported the design and quality assessment of four whole genome oligonucleotide microarrays for two syntroph bacteria, Desulfovibrio vulgaris and Syntrophobacter fumaroxidans, and two archaeal methanogens, Methanosarcina barkeri, and Methanospirillum hungatei, and their application to analyze global gene expression in a four-species microbial community in response to oxidative stress. In order to minimize the possibility of cross-hybridization, cross-genome comparison was performed to assure all probes unique to each genome so that the microarrays could provide species-level resolution. Microarray quality was validated by the good reproducibility of experimental measurements of multiple biological and analytical replicates. This study showed that S. fumaroxidans and M. hungatei responded to the oxidative stress with up-regulation of several genes known to be involved in reactive oxygen species (ROS) detoxification, such as catalase and rubrerythrin in S. fumaroxidans and thioredoxin and heat shock protein Hsp20 in M. hungatei. However, D. vulgaris seemed to be less sensitive to the oxidative stress as a member of a four-species community, since no gene involved in ROS detoxification was up-regulated. Our work demonstrated the successful application of microarrays to a multiple-species microbial community, and our preliminary results indicated that this approach could provide novel insights on the metabolism within microbial communities.

AN - 742772841; pmid-17552696 AB - The separation of components in a gas mixture is important for a wide range of applications. One method for achieving this separation is by passing a traveling acoustic wave through the gas mixture, which creates a flux of the lighter components away from the transducer. A series of simulations was performed to assess the effectiveness of this method for separating a binary mixture of argon and helium using the lattice kinetics method. The energy transport equation was modified to account for adiabatic expansion and compression. The species transport equation was modified to include a barodiffusion term. Simulations were performed on two different scales; detailed acoustic wave simulations to determine the net component flux as a function of local concentration, pressure, etc. and device scale simulations to predict the gas composition as a function of time inside a gas separation cylinder. The method is first validated using data from literature and then applied to mixtures of argon and helium. Results are presented and discussed.

One such signature is stable isotope ratios, which in heterotrophs, are a function of nutrient and water sources. Here we discuss the use of stable isotope ratios in microbial forensics, using as a database the carbon, nitrogen, oxygen, and hydrogen stable isotope ratios of 247 separate cultures of Bacillus subtilis 6051 spores produced on a total of 32 different culture media. In the context of using stable isotope ratios as a signature for sample matching, we present an analysis of variations between individual samples, between cultures produced in tandem, and between cultures produced in the same medium but at different times. Additionally, we correlate the stable isotope ratios of carbon, nitrogen, oxygen, and hydrogen for growth medium nutrients or water with those of spores and show examples of how these relationships can be used to exclude nutrient or water samples as possible growth substrates for specific cultures.

AN - 70567181; 17547182 AB - A series of U(VI) sorption experiments with varying pH, ionic strength, concentrations of dissolved U(VI), and alkalinity was conducted to provide a more realistic database for U(VI) sorption onto near-field vadose zone sediments at the proposed Integrated Disposal Facility (IDF) on the Hanford Site, Washington. The distribution coefficient (Kd) for U(VI) in a leachate that is predicted to result from the weathering of vitrified wastes disposed in the IDF is 0 mL/g due to the high sodium and carbonate concentrations and high pH of the glass leachate. However, when the pH and alkalinity of the IDF sediment native pore water increases during mixing with the glass leachate, U(VI) uptake is observed and the value of the U(VI) Kd increases 4.3 mL/g, because of U(VI) coprecipitation with newly formed calcite. A nonelectrostatic, generalized composite approach for surface complexation modeling was applied and a combination of two U(VI) surface species, monodentate (SOUO2+), and bidentate (SO2UO2(CO3)2-), simulated the measured U(VI) sorption data very well. The generalized composite surface complexation model, when compared to the constant or single-valued Kd model, more accurately predicted U(VI) sorption under the varying geochemical conditions expected at the IDF.

Well, those that were not already on high ground or could not get out of the way of the floods were likely swept to their deaths, many coming to rest in quiet slackwater areas along the floods' route including the shoreline of temporary Lake Lewis. Likewise, some older fossil remains present in the loess and other sediments scoured by the floods were likely eroded and transported away from their previous resting places. Still other fossil remains likely floated in on icebergs that accompanied the floodwaters. Rapid burial in flood deposits is an ideal environment for preservation of fossils. Large numbers of fossils, including those of mollusks, rodents, mammoths, and other vertebrates, have been found in the Mid-Columbia Basin primarily in fine-grained slackwater deposits of the Ice Age floods. Among the most frequently found fossils in these fine-grained sediments is the Columbian Mammoth (Mammuthus columbi). Mammoth fossils are particularly common throughout Washington State, with finds numbering to several hundred. In March 1998, the Columbian Mammoth was named the "official fossil" of the State of Washington. Recent efforts to catalog the location, elevation, geologic context, and relative age of mammoth finds in the Mid-Columbia Basin, have found a predominance of sites located at an elevation of between 300 and 380 m MSL, consistent with the maximum water level of temporary Lake Lewis. Many of these sites are disarticulated, but fairly complete skeletons, suggesting little disturbance after decomposition of the carcass. The location of these finds and their geologic context suggests that, indeed, the humungous Ice Age floods may have had catastrophic impacts on mammoths and other large mammals in southeastern Washington.

An estimated 1,000 metric tons of the material was discharged into the ground in the central portion of Washington State's Hanford Site from 1955 to 1973; however, a significant fraction of the original discharged material cannot be detected or accounted for. Extensive modeling and transport research is providing new insights into migration of CCl (sub 4) beneath the Hanford disposal facilities. Modeling contaminant transport at the Hanford Site is complicated by spatial variations in its subsurface geology. A combination of fluvial deposits, calcrete, loess, and younger silts, sands, and gravels deposited by numerous catastrophic ice age floods compose the site's aquifer and thick vadose zone. Past erosional and depositional events result in uncertainty as to the location of contacts between sedimentary units, and contaminant movement is strongly influenced by variations in sediment texture and composition. While the site is well-studied, a more detailed, lithofacies-based geologic model is needed to improve predictions of future contaminant migration. We show how the geologic model is being improved by the integration of our interpretation of geophysical logs and geologists' drilling records with laboratory measurements quantifying carbon tetrachloride concentrations along the primary groundwater flowpath.

The availability and quality of the geologic storage resource varies from one region of the United States to another, and in the Pacific Northwest, this resource varies significantly, even across short distances. In Washington and Oregon, there may be a number of likely geologic targets, located in tectonically stable areas and at suitable depths to ensure the pressures and temperatures necessary to maintain CO (sub 2) in its supercritical state. These targets include deep, saline-filled sedimentary formations, unmineable coal beds, and flood basalts. Supercritical C (sub 2) can be injected into these formations and stored over very long timeframes via dissolution into the formation fluids, hydrodynamic trapping, or mineralization. Because of their ability to store significant amounts of CO (sub 2) via all three of these mechanisms, and because they may represent the largest CO (sub 2) storage resource available to the Pacific Northwest, the Columbia River Basalt Group represents an attractive target for sequestration. Though a high-potential target, the Columbia River Basalts also pose some of the greatest technical challenges for the critical seismic imaging component of reservoir characterization. Characterization of a potential storage formation includes an assessment of the ability of the formation to retain the injectate over very long periods of time, including assessing the integrity of the impermeable seal, determining and mitigating the presence of existing wellbores, and identification of transmissive faults and faults that may be near their critical stress limits. 3D seismic data, in combination with petrophysical log and rock data, represents one of the most valuable tools in assessing storage capacity, injectivity, and suitability for long-term retention of injected CO (sub 2) . 4D seismic analysis is a key technology in tracking the geometry of the injected plume over time. We review the role of multi-trace geometric attributes to assess structural aspects of potential geologic storage reservoirs, the role of seismic frequency attributes to help quantify CO (sub 2) saturations, and some of the issues and advances in seismically imaging basalt reservoirs.

Such quantitative measures are necessary as management and regulatory agencies within the Pacific Northwest region of the USA, and elsewhere, seek to quantify potential spawning habitat and develop recovery goals for declining salmon populations. The objective of this study was to determine if fall Chinook salmon (Oncorhynchus tshawytscha) spawning areas in the Snake River, Idaho, USA, were correlated with specific bedform types at the pool-riffle scale. A bedform differencing technique was used to objectively quantify the longitudinal riverbed profile into four distinct pool-riffle units that were independent of discharge. The vertical location of thalweg points within these units was quantified with a riffle proximity index. Chinook salmon spawning areas were mapped and correlated with the pool-riffle units through the use of cross-tabulation tables. The results indicate that 84% of fall Chinook salmon spawning areas were correlated with riffles (chi (super 2) = 57.5, df = 3, p<0.001), with 53% of those areas located on the upstream side of riffle crests. The majority of Snake River fall Chinook salmon spawning occurred at elevations greater than 80% of the difference in elevation between the nearest riffle crest and pool bottom. The analyses of bedform morphology will assist regional fish managers in quantifying existing and potential fall Chinook salmon spawning habitat, and will provide a quantitative framework for evaluating general ecological implications of channel morphology in large gravel-bed rivers.

S. oneidensis (and other microoragnisms) are known to develop a structured network of electron- conductive bacterial nanowires as a response to electron acceptor limitation conditions. We show that strong voltage gradients (SP) were concomitant with redox potential gradients in the MR-1 column but absent in the mutant columns. We hypothesize that deeply submerged (suffocating) cells gain access to oxygen through the nanowire network which extends to the groundwater - atmospheric air interface. The nanowires serve as conduits for transfer electrons from bacteria in the anaerobic part of the column to bacteria at the surface that have access to oxygen. We suggest that this process is directly linked with SP and redox gradients that develop across the column. We also observed that in the absence of conductive nanowires (or other conductors) redox potential gradients do not necessarily promote SP gradients as documented in our control columns. Our results suggest that microbial activity and nanowires greatly impact the electrical properties of porous materials and contribute to our understanding of the mechanisms that underlie geophysical methods for mapping microbial activity in near subsurface environments.

The stability and numerical accuracy of the SPH-based model was verified by comparing its results with analytical results and finite element numerical solutions. The numerical stability of the model was also verified by performing simulations with different time steps and different number of particles (different resolutions). The model was used to study the effects of the Damkohler and Peclet numbers and pore-scale heterogeneity on reactive transport and the character of mineral precipitation and to estimate effective reaction coefficients and mass transfer coefficients. Depending on the combination of Damkohler and Peclet numbers the precipitation may be uniform throughout the porous domain or concentrated mainly at the boundaries where the solute is injected and along preferential flow paths. The effective reaction rate coefficient and mass transfer coefficient exhibited hysteretic behavior during the precipitation process as a result of changing pore geometry and solute distribution. The changes in porosity and fluid fluxes resulting from mineral precipitation were also investigated. It was found that the reduction in the fluid flux increases with increasing Damkohler number for any particular reduction in the porosity. The simulation results show that the SPH, Lagrangian particle method is an effective tool for studying pore-scale flow and transport. The particle nature of SPH models allows complex physical processes such as diffusion, reaction, and mineral precipitation to be modeled with relative ease.

Using deuterated methane gas to form gas hydrate in the core sample, it was discovered that resonance amplitudes are correlated with the fraction of the pore space occupied by the gas hydrate crystals. A pore water freezing model was developed that utilizes the known pore size distribution and pore water chemistry to predict gas hydrate saturation as a function of pressure and temperature. The model showed good agreement with the experimental measurements and demonstrated that pore water chemistry is the most important factor controlling equilibrium gas hydrate saturations in these sediments when gas hydrates are formed artificially in laboratory pressure vessels. With further development, the resonant ultrasound technique can provide a rapid, nondestructive, field portable means of measuring the equilibrium P-T properties and dissociation kinetics of gas hydrates in porous media, determining gas hydrate saturations, and may provide new insights into the nature of gas hydrate formation mechanisms in geologic materials.

Samples were analyzed on a Perkin Elmer ELAN DRC II ICP-MS after minimal dilution using O (sub 2) as the reaction gas. Analysis of continuing calibration verification standards indicated that the dynamic reaction cell (DRC) mode could be used for quantitative analysis of (super 129) I in samples below the MCL (0.0057 ng/mL or 1 pCi/L). The low analytical detection limit of (super 129) I analysis in the DRC mode coupled with minimal sample dilution (1.02x) resulted in a final estimated quantification limit of 0.0051 ng/mL. Subsequent analysis of three groundwater samples containing (super 129) I resulted in fully quantitative results in the DRC mode, and spike recovery analyses performed on all three samples confirmed that the groundwater matrix did not adversely impact the analysis of (super 129) I in the DRC mode. This analytical approach has been proven to be a cost-effective, high-throughput technique for the direct, quantitative analysis of (super 129) I in groundwater samples at environmentally relevant concentrations that reach below the current MCL.

Because of the lack of suitable tissue culture or animal models, the true nature of norovirus pathogenesis remains unknown. We show for the first time that noroviruses can infect and replicate in a physiologically relevant 3-dimensional (3-D), organold model of human small intestinal epithelium. This level of cellular differentiation was achieved by growing the cells on porous collagen-I coated microcarrier beads under conditions of physiological fluid shear in rotating wall vessel (RWV) bioreactors. This level of cellular differentiation was achieved by growing the cells on porous collagen-I coated microcarrier beads under conditions of physiological fluid shear in rotating wall vessel bioreactors. Microscopy, PCR, and fluorescent In situ hybridization provided evidence of norovirus Infection. Cytopathic effect and norovirus RNA were detected at each of the 5 cell passages for genogroup I and II viruses. Our results demonstrate that the highly differentiated 3-D cell culture model can support the natural growth of human noroviruses, whereas previous attempts that used differentiated monolayer cultures failed.

After calcination in dry air at 1000 degree C, the XRD and solid state super(27)Al MAS NMR results confirm that stable surface BaO and bulk BaAl sub(2)O sub(4) phases are formed for 8 and 20 wt% BaO/Al sub(2)O sub(3), respectively. Following NO sub(2) adsorption over these thermally treated samples, some evidence for nanosized Ba(NO sub(3)) sub(2) particles are observed in the XRD results, although this may represent a minority phase. However, when water was added to the thermally aged samples after NO sub(2) exposure, the formation of bulk crystalline Ba(NO sub(3)) sub(2) particles was observed in both samples. Solid state super(27)Al MAS NMR is shown to be a good technique for identifying the various Al species present in the materials during the processes studied here. NO sub(2) TPD results demonstrate a significant loss of uptake for the 20 wt% model catalysts upon thermal treatment. However, the described phase transformations upon subsequent water treatment gave rise to the partial recovery of NO sub(x) uptake, demonstrating that such a water treatment of thermally aged catalysts can provide a potential method to regenerate LNT materials.

AN - 68418436; 17098817 AB - The rapid growth in the use of in vitro methods for nanoparticle toxicity assessment has proceeded with limited consideration of the unique kinetics of these materials in solution. Particles in general and nanoparticles specifically, diffuse, settle, and agglomerate in cell culture media as a function of systemic and particle properties: media density and viscosity and particle size, shape, charge and density, for example. Cellular dose then is also a function of these factors as they determine the rate of transport of nanoparticles to cells in culture. Here we develop and apply the principles of dosimetry in vitro and outline an approach for simulation of nanoparticle particokinetics in cell culture systems. We illustrate that where equal mass concentrations (mug/ml) imply equal doses for dissimilar materials, the corresponding particle number or surface area concentration doses differ by orders of magnitude. More importantly, when rates of diffusional and gravitational particle delivery are accounted for, trends and magnitude of the cellular dose as a function of particle size and density differ significantly from those implied by "concentration" doses. For example, 15-nm silver nanoparticles appear approximately 4000 times more potent than micron-sized cadmium oxide particles on a cm(2)/ml media basis, but are only approximately 50 times more potent when differences in delivery to adherent cells are considered. We conclude that simple surrogates of dose can cause significant misinterpretation of response and uptake data for nanoparticles in vitro. Incorporating particokinetics and principles of dosimetry would significantly improve the basis for nanoparticle toxicity assessment, increasing the predictive power and scalability of such assays.

These cytochrome proteins are of great interest because they are thought to mediate bacterial electron transfer reactions in anoxic waters that control the reductive dissolution of oxide minerals. In our study, to characterize the electron transfer properties of these proteins on a model surface, the purified cytochromes were chemically immobilized as molecular monolayers on Au(111) substrates via a recombinant tetra-cysteine sequence as verified by X-ray photoelectron spectroscopy. Atomic force microscopy images confirm the monolayer films were approximately 5-8 nm thick which is consistent with the apparent lateral dimensions of individual cytochrome molecules obtained with STM. Current-voltage TS of single cytochrome molecules revealed that OmcA and MtrC have different abilities to mediate tunneling current despite having otherwise very similar molecular and biochemical properties. These observations suggest that, based on their electron tunneling properties, the two cytochromes could have specific roles during bacterial metal reduction. Additionally, this study establishes single-molecule STM/TS as an effective means for revealing insights into biogeochemical redox processes in the environment.

Soil from the Hanford Formation in the U.S. Department of Energy Hanford Site, Washington, was used in this study. The impact of water chemistry and soil treatment on U(VI) immobilization and the role of gas humidity on soil treatment were investigated. The study revealed that soil uptake of U(VI) from deionized water was much higher than that from the simulated Hanford groundwater. Nevertheless, gas-treated soil was still shown to have the potential for immobilizing U(VI) from the simulated groundwater. In addition, changes in H (sub 2) S column breakthrough indicated that humidity enhanced the reduction of soil Fe. In the first 20 pore volumes, the soil treated with moisturized H (sub 2) S gas can effectively immobilize >80% of the mobile U(VI). Primary mechanisms for U immobilization included U(VI) sorption to the sediments, reduction of U(VI) to insoluble U(IV), and enhanced adsorption of U(VI) to newly formed Fe oxides. Remobilization of U following reoxidation of the sediment was relatively insignificant under the experimental conditions applied, apparently owing to the enhanced adsorption of U to poorly crystallized hydrous ferric oxide products.

Although previous strategies for the identification of these proteins have traditionally required laborious protein purification/characterization of metal-reducing capability, activity is often lost before the final purification step, thus creating a significant knowledge gap. In the current study, subcellular fractions of Shewanella oneidensis MR-1 were enriched for Fe(III)-NTA reducing proteins in a single step using several orthogonal column matrices. The protein content of eluted fractions that demonstrated activity was determined by ultra-high pressure liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). A comparison of the proteins identified from active fractions in all separations produced 30 proteins that may act as the terminal electron-accepting protein for Fe(III)-reduction. These include MtrA, MtrB, MtrC and OmcA as well as a number of other proteins not previously associated with Fe(III)-reduction. This is the first report of such an approach where the laborious procedures for protein purification are not required for identification of metal-reducing proteins. Such work provides the basis for a similar approach with other cultured organisms as well as analysis of sediment and groundwater samples from biostimulation efforts at contaminated sites.

The results show that the number of displaced atoms generated at the same PKA energy is similar in silica and cristobalite but the number of coordination defects created is much lower in the cristobalite than in silica glass. In both cases, the erbium ion is able to create an optimal coordination environment at the end of the collision cascade. Subsequent thermal annealing causes the relaxation of the silicon oxygen network structure along with a reduction of silicon and oxygen defects.

In this study, a set of three closely located genes, DVU2103, DVU2104, and DVU2108 of D. vulgaris, was found to be up-regulated 2- to 4-fold following the lifestyle shift from syntroph to sulfate reducer; moreover, none of the genes in this gene set were differentially regulated when comparing gene expression from various D. vulgaris pure culture experiments. Although exact function of this gene set is unknown, the results suggest that it may play roles related to the lifestyle change of D. vulgaris from syntroph to sulfate reducer. This hypothesis is further supported by phylogenomic analyses showing that homologies of this gene set were only narrowly present in several groups of bacteria, most of which are restricted to a syntrophic lifestyle, such as Pelobacter carbinolicus, Syntrophobacter fumaroxidans, Syntrophomonas wolfei, and Syntrophus aciditrophicus. Phylogenetic analysis showed that all three individual genes in the gene set tended to be clustered with their homologies from archaeal genera, and they were rooted on archaeal species in the phylogenetic trees, suggesting that they were horizontally transferred from archaeal methanogens. In addition, no significant bias in codon and amino acid usages was detected between these genes and the rest of the D. vulgaris genome, suggesting the gene transfer may have occurred early in the evolutionary history so that sufficient time has elapsed to allow an adaptation to the codon and amino acid usages of D. vulgaris. This report provides novel insights into the origin and evolution of bacterial genes linked to the lifestyle change of D. vulgaris from a syntrophic to a sulfate-reducing lifestyle.

AN - 68982064; 17278489 AB - The purpose of this study was to calculate a more accurate dose rate constant for the 131Cs (model CS-1, IsoRay Medical, Inc., Richland, WA) interstitial brachytherapy seed. Previous measurements of the dose rate constant for this seed have been reported by others with incongruity. Recent direct measurements by thermoluminescence dosimetry and by gamma-ray spectroscopy were about 15% greater than earlier thermoluminescence dosimetry measurements. Therefore, we set about to calculate independent values by a Monte Carlo approach that combined three estimates as a consistency check, and to quantify the computational uncertainty. The calculated dose rate constant for the 131Cs seed was 1.040 cGy h(-1) U(-1) for an ionization chamber model and 1.032 cGy h(-1) U(-1) for a circular ring model. A formal value of 2.2% uncertainty was calculated for both values. The range of our multiestimate values were from 1.032 to 1.061 cGy h(-1) U(-1). We also modeled three 125I seeds with known dose rate constants to test the accuracy of this study's approach.

AN - 68381088; 17119936 AB - Biomonitoring of lead (Pb) in blood and urine enables quantitative evaluation of human occupational and environmental exposures to Pb. State-of-the-art ICP-MS instruments can only analyze metals in laboratories, resulting in lengthy turnaround times, and they are expensive. In response to the growing need for a metal analyzer capable of on-site, real-time monitoring of trace toxic metals in individuals, we developed a portable microanalyzer based on flow-injection/stripping voltammetry (ASV), and validated the system using rat blood and urine spiked with known amounts of Pb. Fouling of electrodes by proteins often prevents the effective use of electrochemical sensors in biological matrices. Minimization of such fouling was accomplished with suitable sample pretreatment and by establishing turbulent flow of blood and urine containing Pb onto the electrode inside the microanalyzer, which resulted in no apparent electrode fouling even when the samples contained 50% urine or 10% blood by volume. No matrix effect was observed for the voltammetric Pb signals, even when the samples contained 10% blood or 10% urine. The microanalyzer offered linear concentration ranges relevant to Pb exposure levels in humans (0-20 ppb in 10% blood samples, 0-50 ppb in 50% urine samples). The device showed excellent sensitivity and reproducibility; Pb detection limits were 0.44 ppb and 0.46 ppb, and % R.S.D. was 4.9 and 2.4 in 50% urine and 10% blood samples, respectively. It gave similar Pb concentrations in blood and urine to those measured by ICP-MS. It offered high throughput (3 min per sample) and economical use of samples (60 microL per measurement) as well as low reagent consumption (1 microg of Hg per measurement), thus minimizing environmental concerns associated with mercury use. Since it is miniaturized, the microanalyzer is portable and field-deployable. Thus, it shows much promise as the next-generation analyzer for the biomonitoring of toxic metals.

Sr (super 2+) , (super 90) Sr (super 2+) , Mg (super 2+) , and Ca (super 2+) was desorbed and total inorganic carbon concentration was monitored during the equilibration of this sediment with varying concentrations of Na (super +) , Ca (super 2+) . A cation exchange model previously developed for similar sediments was applied to these results as a predictor of final solution compositions. The model included binary exchange reactions for the four operant cations and an equilibrium dissolution/precipitation reaction for calcite. The model successfully predicted the desorption data. The contaminated sediment was also examined using digital autoradiography, a sensitive tool for imaging the distribution of radioactivity. The exchanger phase containing (super 90) Sr was found to consist of smectite formed from weathering of mesostasis glass in basaltic lithic fragments. These clasts are a significant component of Hanford formation sands. The relatively small but significant cation exchange capacity of these sediments was thus a consequence of reaction with physically sequestered clays in sediment that contained essentially no fine-grained material. The nature of this exchange component explained the relatively slow (scale of days) evolution of desorption solutions. The experimental and model results indicated that there is little risk of migration of (super 90) Sr (super 2+) to the water table.

Beginning ca. 17 Ma, successive outpourings of Columbia River basalt spread for hundreds of kilometers from volcanic vents located in the southern and eastern Columbia Plateau. Up to 300 separate basalt flows have been identified, reaching cumulative thicknesses of 5 km in the Pasco Basin. With the close of basalt volcanism ca. 6 Ma, only a few million years elapsed before the Pacific Northwest succumbed to a new era of flooding. Outburst floods are associated with regular glacial cycles that have occurred periodically over the past 1-2 m.y. from one or more Pleistocene, ice-marginal lakes. During the last glacial cycle (15,000-20,000 calendar yr) alone, as many as 100 separate flood events, mostly from glacial Lake Missoula, are postulated. In the Channeled Scabland, after removing a blanket of loess, differential erosion through hundreds of meters of layered basalt with widely contrasting variations in fracture patterns and structure resulted in a unique assemblage of erosional landforms including multi-tiered cataract canyons, buttes, mesas, and rock basins. A number of depositional features, including huge flood bars blanketed with giant current ripples, as well as ice-rafted erratics and bergmounds, are also prevalent.

However, chromium has been detected in several wells, indicating a premature loss of the reductive capacity in the aquifer. One possible cause for premature chromate breakthrough is associated with the presence of high-permeability zones in the aquifer. The potential emplacement of zero-valent iron (Fe (super 0) ) into high-permeability Hanford sediments to enhance the barrier's reductive capacity using shear-thinning fluids containing polymers was investigated in three-dimensional wedge-shaped aquifer models. Porous media were packed in the wedge-shaped flow cell to create either a heterogeneous layered system with a high-permeability zone between two low-permeability zones or a high-permeability channel surrounded by low-permeability materials. The injection flow rate, polymer type, polymer concentration, and injected pore volumes were determined based on preliminary short-and long-column experiments. The flow cell experiments indicated that iron concentration enhancements of at least 0.6% w/w could be obtained using moderate flow rates and injection of 30 pore volumes. The aqueous pressure increased by a maximum of 25 kPa during infiltration, but a decrease in permeability was not observed. Under optimal conditions, the 0.6% amended Fe (super 0) concentration would provide approximately 20 times the average reductive capacity that is provided by the dithionite-reduced Fe(II) in the ISRM barrier.

The test involved injecting hydrogen sulfide, diluted in air, into contaminated vadose zone sediment to reduce Cr(VI) to Cr(III). The gaseous mixture was injected directly into the contaminated sediment through a central injection well and vacuum extracted through the flow field with six boreholes at the site periphery over a 76-d period. Comparison of soil samples taken before and after the test indicated 70% of the total mass of hexavalent chromium originally present at the site was reduced and immobilized. The zone of highest contamination was nearly completely treated, with average Cr(VI) concentrations decreasing in this interval from an average of 8.1 mg/kg before treatment to 1.1 mg/kg after treatment. Treatment was best in higher permeability clean gypsum sands and less effective in zones containing greater amounts of silt and clay and a slightly higher iron content. All hexavalent chromium concentrations measured in the post-test samples, however, were well below the remedial goal and regulatory limit of 30 mg/kg. In addition, the field test demonstrated that vadose zone treatment of contamination can be safely conducted using diluted hydrogen sulfide gas mixtures. Ongoing development of the technology is being directed toward addressing the limitations of gaseous treatment arising from variations in sediment permeability and iron content and assessing the relationship between hydrogen sulfide consumption and reaction kinetics.

Laboratory microcosms with these sediments showed TCE dechlorination at 70 degrees C with measured products of acetylene, ethene, and ethane, indicating an abiotic component of the degradation. In contrast, TCE was dechlorinated to cis-1,2-dichloroethene in experiments at 10 degrees C, likely by biological reductive dechlorination. The observed products at 70 degrees C suggest dechlorination catalyzed by reduced sediment iron. Indications of in situ dechlorination were observed in periodic ground water samples collected during field-scale ERH from an average ambient temperature of about 19 degrees C to near boiling. Dechlorination indicators included an increase in chloride concentration at the onset of heating and observation of acetylene, ethene, and methane at elevated temperatures. The data collected in this study suggest that dechlorination can occur during ERH. The overall cost-effectiveness of ERH may be enhanced by fortuitous in situ dechlorination and, potentially, could be further enhanced by specifically designing and operating ERH to maximize in situ dechlorination.

These geometric attributes include the well-established coherence technology, coupled with recent developments in spectrally limited estimates of volumetric curvature. Coherence measures lateral changes in waveform, and as such, is often sensitive to joints, small faults, sinkholes and collapse features. The many components of reflector curvature, including the most negative, most positive, Gaussian curvature and related shape indices (e.g. valleys, saddles, domes), are complimentary to coherence measures. Short wavelength estimates of curvature will illuminate small-scale lineaments while longer wavelength estimates of curvature illuminate more subtle flexures and compaction features. We show the results of applying a variety of multi-trace geometric attributes to a three-dimensional seismic volume from the Fort Worth Basin, where a collapse system extends vertically some 800 m from the Ordovician Ellenburger carbonates through the dominantly siliciclastic Mississippian-Pennsylvanian interval. The collapse features in our data set appear as rounded, sinkhole-like appearances on time and horizon slices in the Pennsylvanian Marble Falls Limestones and the Ellenburger horizon displays features that can be interpreted as cockpit karst, dolines and frying pan valleys. Although a variety of palaeocave breccia facies in core and image logs indicate that the Ellenburger surface has been karsted, these breccias are not confined to the mega collapse features visible in seismic. The large (up to 700 m diameter) collapse chimneys can be shown in multi-spectral curvature attributes to have elongate rhombohedral shapes associated with intersections of Pennsylvanian age, field-scale to basin-scale, basement lineaments and faults. Isochores indicate greatest tectonic growth on faults from Mississippian until early Pennsylvanian, coincident with thickest fill of collapse features. Thus we interpret the origin of the chimneys to be primarily tectonic. The multi-trace geometric attributes permit better imaging of the three-dimensional shapes of the collapse features, provide better constraints on timing of their formation, allow us to begin to separate karst processes from tectonic processes and provide a means of predicting most likely locations of fluid movement along faults.

Available at the selected test site were two sets of water content data derived from neutron probe measurements that had been made to a depth of approximately 18 m in 32 wells in 1980 and 1995. The comparison of probe-derived water content data, synthetic radar data, and the acquired radar data indicated a good correspondence between the changes in probe-derived water content and the location of reflections in the radar data. Geostatistical analysis was conducted on the two sets of probe-derived water content values and the amplitudes of the reflections in the radar reflection image to determine the horizontal correlation length of water content. The experimental semivariograms for the water content data were fit with a single exponential model with a correlation length of 10 m. The semivariogram for the radar data was fit with a nested structure containing a dominant long-range structure with a correlation length of 14 m, and a smaller-scale structure with a correlation length of 0.3 m. Quantifying the scale triplet--the spacing, extent, and support--for the two forms of measurement provided a framework for comparing and assessing the derived correlation structures. This approach also highlighted the importance of identifying methods for properly determining the scale of radar measurements required for the imaging of subsurface water content.

The result is a multitude of new concepts and designs, but little data on how well and under what circumstances these innovations are effective. New products, technologies, and concepts are frequently implemented without knowledge of their impacts on work, much less their value to high-level organizational goals. The measurement most commonly used is still cost, or even less sensibly, square feet. To remedy this shortcoming, the U.S. General Service Administration's Public Buildings Service assembled an interagency research team and recognized academic and private sector leaders to identify `best practice' workplace strategies and the research tools holding the most promise for evaluating their impact. They evaluated the linkages among organizational performance (Business), the physical attributes of the workspace (Building), and the changes in work processes, perceptions, and attitudes that result from changes to this physical space (Behavior). This article provides an overview of the GSA program and preliminary results from two pilot projects.

In order to identify better surface chemistries for antibody capture, a number of commercial companies and academic research groups have developed new slide types that could improve antibody function in microarray applications. In this review we compare and contrast the commercially available slide chemistries, as well as highlight some promising recent advances in the field.

However, it is not without problems and complications, and its sustainability will increasingly deplete uranium sources and exacerbate spent fuel management demands. Moreover, the once-through uranium fuel cycle encourages expansion of enrichment services, and these could stimulate proliferation. In the paper, the fuel cycle material requirements are examined on the basis of the constraints of existing nuclear power plants and spent fuel storage and reprocessing facilities. Projected changes in population and energy use are considered as drivers for further expansion, and resource projections to support the continued use of the once-through fuel cycle are included. Possible new reactor technologies are briefly described, and proliferation concerns related to different fuel cycles are addressed. JF - FISSILE MATERIAL STRATEGIES FOR SUSTAINABLE NUCLEAR ENERGY.

The spatial variability and complexity of surface water and riverbed temperature gradients results in emergence timing predictions that are likely to have large errors. The objectives of this study were to quantify the thermal heterogeneity between the river and riverbed in fall Chinook salmon spawning areas and to determine the effects of thermal heterogeneity on fall Chinook salmon emergence timing. This study quantified river and riverbed temperatures at 15 fall Chinook salmon spawning sites distributed in two reaches throughout 160 km of the Snake River in Hells Canyon, Idaho, USA, during 3 different water years. Temperatures were measured during the fall Chinook salmon incubation period with self-contained data loggers placed in the river and at three different depths below the riverbed surface. At all sites, temperature increased with depth into the riverbed, including significant differences (p < 0.05) in mean hourly water temperature of up to 3.8 not equal to between the river and the riverbed among all the sites. During each of the 3 water years studied, river and riverbed temperatures varied significantly among all the study sites, among the study sites within each reach and between sites located in the two reaches. Considerable variability in riverbed temperatures among the sites resulted in fall Chinook salmon emergence timing estimates that varied by as much as 36 days within a reach, depending on the source of temperature data used for the estimate. Monitoring of riverbed temperature gradients at a range of spatial scales throughout the Snake River would provide better information for managing hydroelectric dam operations, and would aid in the design and interpretation of future empirical research into the ecological significance of physical riverine processes.

This paper describes a novel graphical model of the teleost brain-pituitary-gonadal (BPG) axis designed for ecotoxicogenomics research on endocrine-disrupting chemicals using small fish models. The model incorporates six compartments representing the major organs involved in the fish reproductive axis and depicts the interactions of over 105 proteins and 40 simple molecules, transcriptional regulation of 25 genes, and over 300 different reactions/processes. Application of the model is illustrated in the context of a study examining effects of the competitive aromatase inhibitor, fadrozole, on gene expression in gonad, brain, and liver tissue of fathead minnows. Changes in mRNA transcript abundance were measured using a fathead minnow oligonucleotide microarray and quantitative real-time polymerase chain reaction. Gene expression changes observed in the ovaries of females exposed to 6.3 mg fadrozole/L for 7 d were functionally consistent with fadrozoles mechanism of action, and expected compensatory responses of the BPG axis to fadrozoles effects. Furthermore, microarray results helped identify additional elements (genes/proteins) that could be included in the model to potentially increase its predictive capacity. With proper recognition of their utility and limitations, graphical models can serve as important tools for linking molecular and biochemical changes to whole organism outcomes.

In-situ and remote-sensing instrumentation was deployed to obtain measurements of wind, temperature, and humidity profiles in the boundary layer and free atmosphere at four primary sampling sites in central Mexico. Several models were run operationally during the field campaign to provide forecasts of the local, regional, and synoptic meteorology as well as the predicted location of the Mexico City pollutant plume for aircraft flight planning purposes. Field campaign measurements and large-scale analyses are used to define three regimes that characterize the overall meteorological conditions: the first regime prior to 14 March, the second regime between 14 and 23 March, and the third regime after 23 March. Mostly sunny and dry conditions with periods of cirrus and marine stratus along the coast occurred during the first regime. The beginning of the second regime was characterized by a sharp increase in humidity over the central plateau and the development of late afternoon convection associated with the passage of a weak cold surge on 14 March. Over the next several days, the atmosphere over the central plateau became drier so that deep convection gradually diminished. The third regime began with the passage of a strong cold surge that lead to humidity, afternoon convection, and precipitation over the central plateau that was higher than during the second regime. The frequency and intensity of fires, as determined by satellite measurements, also diminished significantly after the third cold surge. The synoptic-scale flow patterns that govern the transport of pollutants in the region are described and compared to previous March periods to put the transport into a climatological context. The complex terrain surrounding Mexico City produces local and regional circulations that govern short-range transport; however, the mean synoptic conditions modulate the thermally-driven circulations and on several days the near-surface flow is coupled to the ambient winds aloft.

Enzyme biosensors, which are currently gaining acceptance for environmental monitoring applications, need improvements to deliver faster measurements with stabilized sensing elements, e.g., enzymes. We report here on a method which significantly overcomes this difficulty, and demonstrate its application in a biosensor for aquatic environmental applications. A fast- responding and stable biosensor was developed via immobilization of organophosphorus hydrolase (OPH) in functionalized mesoporous silica (FMS) with pore sizes in tens of nanometers. The OPH-FMS composite was held on glassy carbon electrode by a dried Nafion gel and FMS protected OPH from Nafion- resulted activity loss. The resulting enzyme biosensor, when integrated with an electrochemical instrument, responded rapidly to low paraoxon concentration and achieved steady-state current in less than 10 s, with a detection limit of 4.0 x 10 super(-7) M paraoxon. The biosensor was tested for detection of paraoxon in simulated environmental samples, under wide-ranging physicochemical conditions. Results clearly indicate high recovery efficiencies in aqueous solutions (96 to 101%) at different pH, total organic carbon, total dissolved solids, and total suspended solids, and demonstrate the ability of the biosensor unit to continuously monitor paraoxon in aqueous conditions similar to those found in river and lake systems.

Our research objectives were to investigate interactions of biomolecules with hydrophilic and hydrophobic surfaces and to carry out exploratory experiments aimed at highly selective deposition of spatially defined and uniquely selected biological molecules on surfaces. The apparatus includes a high-transmission electrospray ion source, a quadrupole mass filter, a bending quadrupole that deflects the ion beam and prevents neutral molecules originating in the ion source from impacting the surface, an ultrahigh vacuum (UHV) chamber for ion deposition by soft landing, and a vacuum lock system for introducing surfaces into the UHV chamber without breaking vacuum. Ex situ analysis of surfaces following soft landing of mass- selected peptide ions was performed using 15 keV Ga super(+) time-of-flight secondary ion mass spectrometry and grazing incidence infrared reflection- absorption spectroscopy. It is shown that these two techniques are highly complementary methods for characterization of surfaces prepared with a range of doses of mass-selected biomolecular ions. We also demonstrated that soft landing of peptide ions on surfaces can be utilized for controlled preparation of peptide films of known coverage for fundamental studies of matrix effects in SIMS.

The device takes advantage of the speed and low cost of the conventional immunochromatographic strip test and the high sensitivity of the nanoparticle-based electrochemical immunoassay. A sandwich immunoreaction was performed on the immunochromatographic strip, and the captured QD labels in the test zone were determined by highly sensitive stripping voltammetric measurement of the dissolved metallic component (cadmium) with a disposable screen-printed electrode, which is embedded underneath the membrane on the test zone. The new device coupled with a portable electrochemical analyzer shows great promise for in-field and point- of-care quantitative testing of disease-related protein biomarkers. The parameters (e.g., voltammetric measurement of QD labels, antibody immobilization, the loading amount of QD-antibody, and the immunoreaction time) that govern the sensitivity and reproducibility of the device were optimized with IgG model analyte. The voltammetric response of the optimized device is highly linear over the range of 0.1-10 ng mL super(-1) IgG, and the limit of detection is estimated to be 30 pg mL super(-1) in association with a 7- min immunoreaction time. The detection limit was improved to 10 pg mL super(-1) using a 20-min immunoreaction time. The device has been successfully applied for the detection of prostate-specific antigen (PSA) in human serum sample with a detection limit of 20 pg mL super(-1). The results were validated by using the commercial PSA enzyme-linked immunosorbent assay kit and showed high consistency. The new disposable electrochemical diagnosis device thus provides a rapid, clinically accurate, and quantitative tool for protein biomarker detection.

AN - 20483609; 7950449 AB - Activities to reduce net greenhouse gas emissions by biological soil or forest carbon sequestration predominantly utilize currently known, readily implementable technologies. Many other greenhouse gas emission reduction options require future technological development or must wait for turnover of capital stock. Carbon sequestration options in soils and forests, while ready to go now, generally have a finite life, allowing use until other strategies are developed. This paper reports on an investigation of the competitiveness of biological carbon sequestration from a dynamic and multiple strategy viewpoint. Key factors affecting the competitiveness of terrestrial mitigation options are land availability and cost effectiveness relative to other options including CO sub(2) capture and storage, energy efficiency improvements, fuel switching, and non-CO sub(2) greenhouse gas emission reductions. The analysis results show that, at lower CO sub(2) prices and in the near term, soil carbon and other agricultural/forestry options can be important bridges to the future, initially providing a substantial portion of attainable reductions in net greenhouse gas emissions, but with a limited role in later years. At higher CO sub(2) prices, afforestation and biofuels are more dominant among terrestrial options to offset greenhouse gas emissions. But in the longer run, allowing for capital stock turnover, options to reduce greenhouse gas emissions from the energy system and biofuels provide an increasing share of potential reductions in total US greenhouse gas emissions.

The determination of the protein-protein interaction (PPI) networks has been the subject of extensive research. Despite the development of reasonably successful methods, serious technical difficulties still exist. In this paper we present DomainGA, a quantitative computational approach that uses the information about the domain-domain interactions to predict the interactions between proteins. Results DomainGA is a multi-parameter optimization method in which the available PPI information is used to derive a quantitative scoring scheme for the domain-domain pairs. Obtained domain interaction scores are then used to predict whether a pair of proteins interacts. Using the yeast PPI data and a series of tests, we show the robustness and insensitivity of the DomainGA method to the selection of the parameter sets, score ranges, and detection rules. Our DomainGA method achieves very high explanation ratios for the positive and negative PPIs in yeast. Based on our cross-verification tests on human PPIs, comparison of the optimized scores with the structurally observed domain interactions obtained from the iPFAM database, and sensitivity and specificity analysis; we conclude that our DomainGA method shows great promise to be applicable across multiple organisms. Conclusion We envision the DomainGA as a first step of a multiple tier approach to constructing organism specific PPIs. As it is based on fundamental structural information, the DomainGA approach can be used to create potential PPIs and the accuracy of the constructed interaction template can be further improved using complementary methods. Explanation ratios obtained in the reported test case studies clearly show that the false prediction rates of the template networks constructed using the DomainGA scores are reasonably low, and the erroneous predictions can be filtered further using supplementary approaches such as those based on literature search or other prediction methods.

Sr2+, 90Sr2+, Mg2+, and Ca2+ was desorbed and total inorganic carbon concentration was monitored during the equilibration of this sediment with varying concentrations of Na+, Ca2+. A cation exchange model previously developed for similar sediments was applied to these results as a predictor of final solution compositions. The model included binary exchange reactions for the four operant cations and an equilibrium dissolution/precipitation reaction for calcite. The model successfully predicted the desorption data. The contaminated sediment was also examined using digital autoradiography, a sensitive tool for imaging the distribution of radioactivity. The exchanger phase containing 90Sr was found to consist of smectite formed from weathering of mesostasis glass in basaltic lithic fragments. These clasts are a significant component of Hanford formation sands. The relatively small but significant cation exchange capacity of these sediments was thus a consequence of reaction with physically sequestered clays in sediment that contained essentially no fine-grained material. The nature of this exchange component explained the relatively slow (scale of days) evolution of desorption solutions. The experimental and model results indicated that there is little risk of migration of 90Sr2+ to the water table.

The nuclear magnetic resonance (NMR) structure of PA4608 has been determined and c-di-GMP binding has been confirmed by NMR titration studies. The monomeric core structure of PA4608 contains a six-stranded anti-parallel beta barrel flanked by three helices. Conserved surface residues among PA4608 homologs suggest the c-di-GMP binding site is at one end of the barrel and includes residues in the helices as well as in the unstructured N-terminus. Chemical shift changes in PA4608 resonances upon titration with c-di-GMP confirm binding. This evidence supports the hypothesis that proteins containing PilZ domains are the long-sought c-di-GMP adaptor proteins. Proteins 2007.

Radiation damage by the emission of alpha particles is summarized, and for zircon under increasing doses of alpha - radiation and heavy nuclear recoils, broadening and dislocation of XRD peaks accompanied by swelling, decrease in density and birefringence point to loss of crystallinity. NMR spectroscopy can detect the resulting amorphous and crystalline regions, and (super 29) Si MAS NMR spectra show the effects of increasing cumulative doses of alpha -radiation of natural zircons, with major changes in the local crystal structure around Si atoms with amorphization. Molecular dynamics simulations indicate a cascade of approximately 5000 to 6000 atomic displacements for a 30 keV (super 234) U recoil event in zircons. Relaxation times were characterized from MAS NMR spectra of (super 238) Pu and (super 239) Pu-containing synthetic zircons, and the radiation damage was similar to that caused by (super 238) U and (super 234) Th at the same dosage in natural zircon .Projection of damage accumulation in (super 239) Pu- containing zircon indicates that a 10 wt% Pu-loaded zircon would pass the percolation limit and swell after 210 yr, becoming completely amorphous after 1400 yr (the required minimum immobilization period is 250 000 yr). Ceramic actinide matrices will more likely be titanate or zirconate pyrochlore or structurally related zirconolite materials which can also accommodate other radionuclides.

AN - 57640916; 484399 AB - In the past four years, we have worked with several research programs that were developing intelligent software for use by intelligence analysts. Our involvement in these programs was to develop the metrics and methodologies for assessing the impact on users; in this case, on intelligence analysts. In particular, we focused on metrics to evaluate how much the intelligent systems contribute to the users' tasks and what the cost is to the user in terms of workload and process deviations. In this paper, we describe the approach used. We started with two types of preliminary investigations first, collecting and analyzing data from analysts working in an instrumented environment for a period of 2 years, and second, developing and conducting formative evaluations of research software. The long-term studies informed our ideas about the processes that analysts use and provided potential metrics in an environment without intelligent software tools. The formative evaluations helped us to define sets of application-specific metrics. Finally, we conducted assessments during and after technology insertions. We describe the metrics and methodologies used in each of these activities, along with the lessons learned.

Here, the effect of five cations, Cs (super +) , K (super +) , Sr (super 2+) , Ca (super 2+) and Mg (super 2+) , on mineral formation and transformation pathways under conditions mimicing Hanford tank leaks is investigated. Sodium silicate was used to represent the dissolved silicate from sediments. The silicate was added into a series of simulants that contained 0.5 M aluminate, 1 M or 16 M NaOH, and the NO (sub 3) (super -) salts of the cations. The precipitates were monitored by X-ray diffraction, scanning electron microscopy, and X-ray energy dispersive spectroscopy. In the 1 M NaOH simulants, low concentration of Cs (super +) ( or =250 mM. An unidentified feldspathoid or zeolite intermediate phase was observed in the presence of high concentrations of Cs (super +) (500 mM). The presence of K (super +) did not alter, but slowed, the formation of cancrinite and sodalite. The presence of divalent cations led to the formation of metastable or stable silicates, aluminates, hydroxides, or aluminosilicates. The formation of these intermediate phases slowed the formation of cancrinite and sodalite by consuming OH (super -) , silicate, or aluminate. Compared with the concentrations used in this study, the concentrations of radioactive Cs (super +) and Sr (super 2+) in the tank solutions are much lower and divalent cations (Ca (super 2+) and Mg (super 2+) ) released from sediments likely precipitate out as hydroxides, silicates or aluminates; therefore, the authors do not expect that the presence of these monovalent and divalent cations significantly affect the formation of cancrinite and sodalite in the sediments underneath the leaking waste tanks.

In scientific practice mixture components in the low-dose region, particularly subthreshold doses, are often assumed to behave additively (i.e., zero interaction) based on heuristic arguments. This assumption has important implications in the practice of risk assessment, but has not been experimentally tested. We have developed methodology to test for additivity in the sense of Berenbaum (Advances in Cancer Research, 1981), based on the statistical equivalence testing literature where the null hypothesis of interaction is rejected for the alternative hypothesis of additivity when data support the claim. The implication of this approach is that conclusions of additivity are made with a false positive rate controlled by the experimenter. The claim of additivity is based on prespecified additivity margins, which are chosen using expert biological judgment such that small deviations from additivity, which are not considered to be biologically important, are not statistically significant. This approach is in contrast to the usual hypothesis-testing framework that assumes additivity in the null hypothesis and rejects when there is significant evidence of interaction. In this scenario, failure to reject may be due to lack of statistical power making the claim of additivity problematic. The proposed method is illustrated in a mixture of five organophosphorus pesticides that were experimentally evaluated alone and at relevant mixing ratios. Motor activity was assessed in adult male rats following acute exposure. Four low-dose mixture groups were evaluated. Evidence of additivity is found in three of the four low-dose mixture groups. The proposed method tests for additivity of the whole mixture and does not take into account subset interactions (e.g., synergistic, antagonistic) that may have occurred and cancelled each other out.

Predominantly, two methods emerge as leaders in this application. Intact protein profiling creates fingerprints of bacterial species which can be used for differentiation and tracking over time. Peptide-centric approaches, analyzed after enzymatic digestion, enable high-throughput proteome characterization in addition to species determination from the identification of peptides distinctive to a species. Highlighted herein is an application of a peptide-centric approach to the identification and quantitation of species-specific peptide identifiers using an in silico exploration and an experimental mass spectrometry-based method.

This approach involves the collection of column breakthrough test results at various flow rates, allowing a relationship to be developed between pore velocity of the carrier gas and velocity of the hydrogen sulfide reaction front that permits sizing to the field scale. A regression fit of a set of laboratory column breakthrough test data collected in this study is utilized to illustrate the development of a field design based on a two-dimensional radial flow analytical model. Information regarding treatment time and hydrogen sulfide consumption characteristics associated with in situ gaseous treatment can then be obtained from this model and used as a basis for estimation of treatment schedule and costs. The regression relationship can also be utilized in numerical models in more complex geometries to support the field design of in situ gaseous treatment operations.

The identified proteins corresponded primarily to open reading frames (ORFs) contained within the two chromosomal elements of this bacterium, but a significant number were also observed from ORFs associated with 5 naturally occurring plasmids. Using the accurate mass and time (AMT) tag approach, comparative studies showed that a number of proteins were uniquely detected within the photosynthetic cell culture. The estimated abundances of proteins observed in both aerobic respiratory and photosynthetic grown cultures were compared to provide insights into bioenergetic models for both modes of growth. Additional emphasis was placed on gene products annotated as hypothetical to gain information as to their potential roles within these two growth conditions. Where possible, transcriptome and proteome data for R. sphaeroides obtained under the same culture conditions were also compared.

We observed a dramatic increase of enzyme loading in both enzyme activity and protein amount when using appropriate FMS in comparison with unfunctionalized mesoporous silica and normal porous silica. With different protein loading density in NH2FMS, the negatively charged glucose oxidase (GOX) displayed an immobilization efficiency (Ie, the ratio of the specific activity of the immobilized enzyme to the specific activity of the free enzyme in stock solution) in a range from 30% to 160%, while the same charged glucose isomerase (GI) showed an Ie of 100% to 120%, and the positively charged organophosphorus hydrolase (OPH) exhibited Ie of more than 200% in HOOCFMS. The enzymeFMS composite was stained with the charged gold nanoparticles and imaged by transmission electron microscopy (TEM). Fourier transform infrared (FTIR) spectroscopy showed no major secondary structural change for the enzymes entrapped in FMS. Thanks to the large, rigid, open pore structure of FMS, the reaction rate and Km of the entrapped enzymes in FMS were comparable to those of the free enzymes in solution. In principle, the general approach described here should be applicable to many enzymes, proteins, and protein complexes since both pore sizes and functional groups of FMS are controllable.

As a result of these processes by which water can equilibrate across a membrane, a common assumption is that intracellular water is isotopically indistinguishable from extracellular water. To test this assumption directly, we measured the hydrogen isotope ratio of intracellular water in Escherichia coli cells. Our results demonstrate that more than 50% of the intracellular water hydrogen atoms in log-phase E. coli cells are isotopically distinct from the growth medium water and that these isotopically distinct hydrogen atoms are derived from metabolic processes. As expected, the super(2)H/ super(1)H isotope ratio of intracellular water from log-phase cells showed an appreciably larger contribution from metabolic water than did intracellular water from stationary-phase cells (53 plus or minus 12 and 23 plus or minus 5%, respectively). The super(2)H/ super(1)H isotope ratio of intracellular water was also monitored indirectly by measuring the isotope ratio of fatty acids, metabolites that are known to incorporate hydrogen atoms from water during biosynthesis. Significantly, the difference in the isotopic composition of intracellular water from log- to stationary-phase E. coli cells was reflected in the hydrogen isotope ratio of individual fatty acids harvested at the two different times, indicating that the isotope ratio of metabolites can be used as an indirect probe of metabolic activity. Together, these results demonstrate that contrary to the common assumption that intracellular water is isotopically identical to extracellular water, these two pools of water can actually be quite distinct.

8055241 AB - This paper uses a selective review of the economic literature on technological change to support four points that are important for interpreting and incorporating technological change into formal models of energy and the environment. The review (1) supports the notion that no single source dominates the process of technological change. It supports roles for R&D and learning-by-doing within an industry, as well as for spillovers from other industries engaged in both of these activities. The literature also (2) supports a strong role for spillovers; (3) indicates that these spillovers are often indirect, requiring own-industry activities to utilize; and (4) indicates that simple experience curve calibrations often used in formal models likely include a range of sources of technological change in addition to learning-by-doing, some of which might not be induced by the sorts of policies typically considered in the climate context.

7146561 AB - High efficiency capillary liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to examine the proteins extracted from Desulfovibrio vulgaris cells across six treatment conditions. While our previous study provided a proteomic overview of the cellular metabolism based on proteins with known functions [W. Zhang, M.A. Gritsenko, R.J. Moore, D.E. Culley, L. Nie, K. Petritis, E.F. Strittmatter, D.G. Camp II, R.D. Smith, F.J. Brockman, A proteomic view of the metabolism in Desulfovibrio vulgaris determined by liquid chromatography coupled with tandem mass spectrometry, Proteomics 6 (2006) 4286-4299], this study describes the global detection and functional inference for hypothetical D. vulgaris proteins. Using criteria that a given peptide of a protein is identified from at least two out of three independent LC-MS/MS measurements and that for any protein at least two different peptides are identified among the three measurements, 129 open reading frames (ORFs) originally annotated as hypothetical proteins were found to encode expressed proteins. Functional inference for the conserved hypothetical proteins was performed by a combination of several non-homology based methods: genomic context analysis, phylogenomic profiling, and analysis of a combination of experimental information, including peptide detection in cells grown under specific culture conditions and cellular location of the proteins. Using this approach we were able to assign possible functions to 20 conserved hypothetical proteins. This study demonstrated that a combination of proteomics and bioinformatics methodologies can provide verification of the expression of hypothetical proteins and improve genome annotation.

AN - 68135105; 17089724 AB - 17alpha-Ethynylestradiol (EE2) is a synthetic estrogen identified in sewage effluents. To understand better the absorption kinetics of EE2 and the induction of vitellogenin (VTG) and estrogen receptor alpha (ERalpha) mRNA, we subjected male rainbow trout (Onchorynchus mykiss) to continuous water exposures of 125 ng/L of EE2 for up to 61 d. Trout were either repetitively sampled for blood plasma or serially killed at selected time intervals. Vitellogenin, ERalpha mRNA, and EE2 were measured using enzyme-linked immunosorbent assay and using quantitative polymerase chain reaction and gas chromatography-mass spectrometry, respectively. In separate experiments, trout were exposed to EE2 for 7 d, and hepatic gene expression was assessed using a low- and high-density cDNA microarray. The EE2 was rapidly absorbed by the trout, with an apparent equilibrium at 16 h in plasma and liver. The ERalpha mRNA levels also increased rapidly, reaching near-peak levels by 48 h. In contrast, plasma levels of VTG continuously increased for 19 d. After 61 d, tissues with the highest levels of VTG were the liver, kidney, and testes. Microarray-based gene expression studies provided unexpected results. In some cases, known estrogen-responsive genes (e.g., ERalpha) were unresponsive, whereas many of the genes that have no apparent link to estrogen function or EE2 toxicity were significantly altered in expression. Of the two microarray approaches tested in the present study, the high-density array appeared to be superior because of the improved quality of the hybridization signal and the robustness of the response in terms of the number of genes identified as being EE2 responsive.

It compares the characteristics and performance of citizen advisory boards established by the U.S. Department of Energy's Environmental Restoration and Waste Management Program (DOE/EM) and by the U.S. Department of Defense's Army (DoD/Army) as a major part of the public participation programs that were undertaken to help the agencies plan and implement the cleanup of their contaminated installations. We first present the elements of the Acceptability Diamond, an evaluative framework developed by the authors through extensive fieldwork on public-federal agency interactions that identify five objectives of agency/public interactions and public participation programs, and link them to existing literature. We then use the Acceptability Diamond as a basis for comparing the performance of the DOE/EM and DoD/Army advisory boards. In the early 1990s, both DOE and DoD participated in the Federal Facilities Environmental Restoration Dialogue Committee (known as the FFER Dialogue Committee) and were influenced by the Committee's recommendations on public participation. However, the Site Specific Advisory Boards (SSABs) subsequently established by DOE/EM and the Restoration Advisory Boards (RABs) subsequently established by DoD and the Army were governed by significantly different policies and management. We describe some of these key differences and compare the performance of the SSABs and RABs.

We incubated BC and BC-soil mixtures at two temperatures (30 degrees C and 70 degrees C), with and without microbial inoculation, nutrient addition, or manure amendment for four months. Abiotic processes were more important for oxidation of BC than biotic processes during this short-term incubation, as inoculation with microorganisms at 30 degrees C did not change any of the measured indicators of surface oxidation. Black C incubated at both 30 degrees C and 70 degrees C without microbial activity showed a decrease in pH (in water) from 5.4 to 5.2 and 3.4, as well as an increase in cation exchange capacity (CEC at pH 7) by 53% and 538% and in oxygen (O) content by 4% and 38%, respectively. Boehm titration and Fourier-transform infrared (FT-IR) spectroscopy suggested that formation of carboxylic functional groups was the reason for the enhanced CEC during oxidation. Analysis of surface properties of BC using X-ray photoelectron spectroscopy (XPS) indicated that the oxidation of BC particles was initiated on the surface. Incubation at 30 degrees C only enhanced oxidation on particle surfaces, while oxidation during incubation at 70 degrees C penetrated into the interior of particles. Such short-term oxidation of BC has significance for the stability of BC in soils as well as for its effects on soil fertility and biogeochemistry.

PCC 51142 has recently been sequenced and observed to contain 35 pentapeptide repeat proteins (PRPs). These proteins, while present throughout the prokaryotic and eukaryotic kingdoms, are most abundant in cyanobacteria. The sheer number of PRPs in cyanobacteria coupled with their predicted location in every cellular compartment argues for important, yet unknown, physiological and biochemical functions. To gain biochemical insights, the crystal structure for Rfr32, a 167-residue PRP with an N-terminal 29-residue signal peptide, was determined at 2.1 Aa resolution. The structure is dominated by 21 tandem pentapeptide repeats that fold into a right-handed quadrilateral beta -helix, or Rfr-fold, as observed for the tandem pentapeptide repeats in the only other PRP structure, the mycobacterial fluoroquinoline resistance protein MfpA from Mycobacterium tuberculosis. Sitting on top of the Rfr-fold are two short, antiparallel alpha -helices, bridged with a disulfide bond, that perhaps prevent edge-to-edge aggregation at the C terminus. Analysis of the main-chain ( Phi , zeta ) dihedral orientations for the pentapeptide repeats in Rfr32 and MfpA makes it possible to recognize the structural details for the two distinct types of four-residue turns adopted by the pentapeptide repeats in the Rfr-fold. These turns, labeled type II and type IV beta -turns, may be universal motifs that shape the Rfr-fold in all PRPs.

Dissociation and reconstitution characteristics at different pH as well as the special cavity structure of apoferritin provides a facile route to prepare nanoparticle labels and avoid the complicated and tedious synthesis process of conventional nanoparticle labels. The optical and electrochemical characteristics of the prepared nanoparticle labels are easily controlled by loading different optical or electrochemical markers. A fluorescence marker (fluorescein anion) and a redox marker [hexacyanoferrate(III)] were used as model markers to load into the cavity of apoferritin nanoparticles for microscopic fluorescence immunoassay and electrochemical immunoassay, respectively. Detection limits of 0.06 (0.39 pM) and 0.08 ng mL super(-1) (0.52 pM) IgG were obtained with fluorescein MLAN and hexacyanoferrate MLANs, respectively. The new nanoparticle labels hold great promise for multiplex protein detection (in connection with nanoparticles loaded with different markers) and for enhancing the sensitivity of other bioassays.

In the presence of hematite, there is a substantial increase in the amplitude of internal protein motions that correlate with metal reduction. Binding is highly favorable, with a partition coefficient of approximately 2 x 10 super(5) ( Delta G super(o), = -28 kJ/mol), where approximately 10 super(14) OmcA proteins bind per cm super(2) to the solid metal surface, indicating the utility of using purified OmcA in the construction of a biofuel cell.

SEBINI can be used to compare and train network inference methods on artificial networks and simulated gene expression perturbation data. It also allows the analysis within the same framework of experimental high-throughput expression data using the suite of (trained) inference methods; hence SEBINI should be useful to software developers wishing to evaluate, compare, refine or combine inference techniques, and to bioinformaticians analyzing experimental data. SEBINI provides a platform that aids in more accurate reconstruction of biological networks, with less effort, in less time.

Model performance is evaluated using a wide range of meteorological, chemistry, and particulate measurements obtained during the 2000 Texas Air Quality Study. The predicted trace gas and particulate distributions were qualitatively similar to the surface and aircraft measurements with considerable spatial variations resulting from urban, power plant, and industrial sources of primary pollutants. Sulfate, organic carbon, and other inorganics were the largest constituents of the predicted particulates. The predicted shortwave radiation was 30 to 40 W m super(-2) closer to the observations when the aerosol optical properties were incorporated into the shortwave radiation scheme; however, the predicted hourly aerosol radiative forcing was still underestimated by 10 to 50 W m super(-2). The predicted aerosol radiative forcing was larger over Houston and the industrial ship channel than over the rural areas, consistent with surface measurements. The differences between the observed and simulated aerosol radiative forcing resulted from transport errors, relative humidity errors in the upper convective boundary layer that affect aerosol water content, secondary organic aerosols that were not yet included in the model, and uncertainties in the primary particulate emission rates. The current model was run in a predictive mode and demonstrates the challenges of accurately simulating all of the meteorological, chemical, and aerosol parameters over urban to regional scales that can affect aerosol radiative forcing.

7123380 AB - We used a comparative genomics approach implemented in the SEED annotation environment to reconstruct the chitin and GlcNAc utilization subsystem and regulatory network in most proteobacteria, including 11 species of Shewanella with completely sequenced genomes. Comparative analysis of candidate regulatory sites allowed us to characterize three different GlcNAc-specific regulons, NagC, NagR, and NagQ, in various proteobacteria and to tentatively assign a number of novel genes with specific functional roles, in particular new GlcNAc-related transport systems, to this subsystem. Genes SO3506 and SO3507, originally annotated as hypothetical in Shewanella oneidensis MR-1, were suggested to encode novel variants of GlcN-6-P deaminase and GlcNAc kinase, respectively. Reconstitution of the GlcNAc catabolic pathway in vitro using these purified recombinant proteins and GlcNAc-6-P deacetylase (SO3505) validated the entire pathway. Kinetic characterization of GlcN-6-P deaminase demonstrated that it is the subject of allosteric activation by GlcNAc-6-P. Consistent with genomic data, all tested Shewanella strains except S. frigidimarina, which lacked representative genes for the GlcNAc metabolism, were capable of utilizing GlcNAc as the sole source of carbon and energy. This study expands the range of carbon substrates utilized by Shewanella spp., unambiguously identifies several genes involved in chitin metabolism, and describes a novel variant of the classical three-step biochemical conversion of GlcNAc to fructose 6-phosphate first described in Escherichia coli.

However those genetic data yield limited attribution information, because many pathogens are genetically very homogeneous. There is a need for more informative forensic analyses for the attribution of the agent to a source and its production method. Chemical compositions such as those provided by elemental and isotopic analyses may provide further insight into production processes and growth media used. Ideally, one may be able to compare known and questioned biological weapon agents to determine the degree of association based on isotopic and elemental contents. Modeling with advanced statistical analyses and extended database could narrow down possible production sources and methods. In support of the U.S. Department of Homeland Security, a series of investigations have been performed to develop and validate methods for high precision isotope ratio and elemental composition analysis. One goal is to identify signatures related to biological weapon agent processing techniques and materials by means of the isotopic and elemental analysis of several bacterial agents that were grown under controlled conditions. Results on method development and analytical characterization will be presented of both "light" (e.g, C, N, O, and H by means of elemental analyzer/gas chromatograph isotope ratio mass spectrometry) and "heavy" isotope ratio measurements (e.g. Sr, Pb by multiple-collector ICP mass spectrometry and multiple-collector thermal ionization mass spectrometry). Effects of growth media and processing on elemental and isotopic profiles will be highlighted. The utility of statistical analysis and the importance of database development are also discussed.

We studied how sediment permeability and river discharge altered the vertical hydraulic gradient (VHG) and water quality of the hyporheic zone within the Hanford Reach of the Columbia River. The Columbia River at Hanford is a large, cobble-bed river where water level fluctuates up to 2 m daily because of hydropower generation. Concomitant with river stage recordings, continuous readings were made of water temperature, specific conductance, dissolved oxygen and water level of the hyporheic zone. The water level data were used to calculate VHG between the river and hyporheic zone. Sediment permeability was estimated using slug tests conducted in piezometers installed into the river bed. The response of water quality measurements and VHG to surface water fluctuations varied widely among study sites, ranging from no apparent response to covariance with river discharge. At some sites, a hysteretic relationship between river discharge and VHG was indicated by a time lag in the response of VHG to changes in river stage. The magnitude, rate of change and hysteresis of the VHG response varied the most at the least permeable location (hydraulic conductivity (K) = 2.9X10 (super -4) cms (super -1) ) and the least at the most permeable location (K = 8.0X10 (super -3) cms (super -1) ). Our study provides empirical evidence that sediment properties and river discharge both control the water quality of the hyporheic zone. Regulated rivers, like the Columbia River at Hanford, that undergo large, frequent discharge fluctuations represent an ideal environment in which to study hydrogeologic processes over relatively short time periods (i.e. days to weeks) that would require much longer periods (i.e. months to years) to evaluate in unregulated systems.

Consequently, the solubility of synthetic Na-boltwoodite, Na(UO (sub 2) )(SiO (sub 3) OH) . 1.5H (sub 2) O, was determined over a wide range of bicarbonate concentrations, from circumneutral to alkaline pH, that are representative of porewater and groundwater compositions at the Hanford site and calcareous environments generally. Experiments were open to air. Results show that Na-boltwoodite dissolution was nearly congruent and its solubility and dissolution kinetics increased with increasing bicarbonate concentration and pH. A consistent set of solubility constants were determined from circumneutral pH (0 added bicarbonate) to alkaline pH (50 mM added bicarbonate). Average log K (super o) (sub sp) = 5.86 + or - 0.24 or 5.85 + or - 0.0.26; using the Pitzer ion-interaction model or Davies equation, respectively. These values are close to the one determined by [Nguyen, S. N., Silva, R. J., Weed, H. C., Andrews, Jr., J. E., 1992.

Quantitative models of biogeochemical reaction systems are based on constituent concentration as the primary dependent variable, which requires assumptions involving scales of averaging and mixing. At laboratory scales, complete mixing and homogeneity conditions can be (and usually are) enforced and resulting theories are conditioned on those assumptions. However, at field scales physical, chemical and biological heterogeneity and incomplete mixing are the rule rather than the exception. Several examples from recent research, including experiments and simulations ranging from pore to field scales, will be presented to illustrate these issues and identify possible solutions. These examples include a combined field- and laboratory-scale study of bacterial transport, a field study of metals bioremediation in a highly heterogeneous aquifer, and pore- to continuum-scale simulations of coupled flow and mineral precipitation reactions.

Historically, these simulations and models have represented the geologic framework and associated flow and transport properties through simple homogenous and horizontally stratified hydrogeologic units. Capturing the heterogeneity, small scale variability, and uncertainty within models is receiving more emphasis due to increasing capabilities of computer systems and the need to develop more detailed and complete depictions of contaminant transport. The ability to improve resolution of models and simulations is limited by the availability of data in a form favorable to computer processing. Geologic borehole information is, for the most part, qualitative in nature and not readily amenable to numerical analysis. Thus, efforts are being made to systematize borehole geologic data, to be used in a more quantitative manner. Detailed procedures have been developed to translate qualitative descriptive information into discrete semi-quantitative parameters, and to translate inconsistent quantitative and semi-quantitative data sets into common parametric data sets. A geologic data management system is being developed to manage these new "translational" data sets and integrate them with existing databases to support their synergistic analysis and improved numerical representation of the subsurface geology. Detailed procedures and uniformed translational processes allow for qualitative data from a variety of sources to be represented in a semi-quantitative and computer accessible form that is thorough, uniform, traceable, and defensible. This process has led to the creation of a detailed representation of the geologic relationship between flow and transport properties of lithofacies and the stratigraphic sequence of those lithofacies beneath the waste disposal facilities at the Hanford Site.

This work supports the U.S. Department of Energy's (DOE's) efforts to characterize the nature and distribution of CT in the 200 West Area and subsequently select an appropriate final remedy. Simulations targeted migration of dense, nonaqueous phase liquid (DNAPL) consisting of CT and co- disposed organics in the subsurface beneath the 216-Z-9 trench as a function of the properties and distribution of subsurface sediments and of the properties and disposal history of the waste. Simulations of CT migration were conducted using the Subsurface Transport Over Multiple Phases (STOMP) simulator. Simulation results support a conceptual model for CT distribution where CT in the DNAPL phase is expected to have migrated primarily in a vertical direction below the disposal trench. Presence of small-scale heterogeneities tends to limit the extent of vertical migration of CT DNAPL due to enhanced retention of DNAPL compared to more homogeneous conditions, but migration is still predominantly in the vertical direction. Results also show that the Cold Creek units retain more CT DNAPL within the vadose zone than other hydrologic unit during SVE. A considerable amount of the disposed CT DNAPL may have partitioned to the vapor and subsequently water and sorbed phases. Presence of small-scale heterogeneities tends to increase the amount of volatilization. Any continued migration of CT from the vadose zone to the groundwater is likely through interaction of vapor phase CT with the groundwater and not through continued DNAPL migration. The results indicated that SVE appears to be an effective technology for vadose zone remediation, but additional effort is needed to improve simulation of the SVE process.

Previous studies have shown that the caustic tank leachate solution with high ionic strength (I=2-8 M NaNO3) and high pH ( similar to 14) conditions dissolves primary minerals (quartz and clays) and forms secondary precipitates on mineral surfaces. The secondary precipitates include zeolite, cancrinite and sodalite. The dissolution followed by precipitation reaction would alter the sediment pore structure as well as the soil surface properties. Both physical and chemical changes of the sediment were found to have an impact on the flow and mobility of radionuclide in unsaturated columns at varying degrees of saturation.

The detection of mouse TNF- alpha via immunological reaction is based on a dual signal amplification: (1) a large amount of guanine residues introduced on the electrode surface through sandwich immunoreaction and poly(guanine)-functionalized silica NP label; (2) Ru(bpy) super(2) sub(3) super(+)-induced catalytic oxidation of guanine, which results in great enhancement of anodic current. The synthesized silica NP conjugates were characterized with atomic force microscopy, X-ray photoelectron spectroscopy, and electrochemistry. These experiments confirmed that poly(guanine) and avidin were immobilized on the surface of silica NPs. The performance of the electrochemical immunosensor was evaluated and some experiment parameters (e.g., concentration of Ru(bpy) super(2) sub(3) super(+), incubation time of TNF- alpha , etc.) were optimized. The detection limit for TNF- alpha is found to be 5.0 x 10 super(-11) g mL super(-1) (2.0 pM), which corresponds to 60 amol of TNF- alpha in 30 mu L of sample. This immunosensor based on the poly(guanine)-functionalized silica NP label offers great promise for rapid, simple, cost-effective analysis of biological samples.

As part of the 2002 New England Air Quality Study (NEAQS), the Nighttime Aerosol/Oxidant Plume Experiment (NAOPEX) was designed to study the chemical evolution and interaction of ambient urban aerosols and trace gases in the absence of photochemistry. Lagrangian measurements of trace gases (O3, NOx, NOy, VOCs, CO) and aerosols (size distribution and composition) were made with the Department of Energy's (DOE) G-1 aircraft in the nocturnal residual layer downwind of greater Boston area. Constant-volume tetroons equipped with GPS, radiosonde, and ozonesonde were used as Lagrangian markers to guide aircraft sampling in the same air mass as it is advected downwind. Here, we report on the July 31 episode when two back-to-back aircraft flights repeatedly sampled a tagged volume of air into which aerosols and trace gases were freshly emitted at sunset time. Aircraft and tetroon data were analyzed using a detailed gas-aerosol Lagrangian box model. The model successfully reproduced the observed ozone loss as a function of time, but systematically underpredicted NO2 mixing ratios. Including a heterogeneous conversion of NO3 radicals to NO on aerosol surfaces can largely explain the discrepancy. Sensitivity of modeled NO2 mixing ratios to processing time, uptake coefficient for the NO3 radical, and the rate of N2O5 hydrolysis to HNO3 will be presented. Implications of the hypothesized reaction on the overall nighttime loss rate of NOx will be discussed.

While measurements of particulate mass, composition, and size distribution have been made in Mexico City, the impact of the particulates on air quality and climate downwind of the city is not known. To better understand the evolution of particulates originating from anthropogenic emissions in Mexico City and their impact on regional air quality and climate, a multi-agency field campaign called the Megacities Initiative: Local And Global Research Observations (MILAGRO) collected a wide range of meteorological, chemical, and particulate measurements during March 2006. One component of MILAGRO was the MAX-Mex (Megacity Aerosol eXperiment Mexico) experiment supported by the U.S. Department of Energy. MAX-Mex obtained particulate and radiation measurements at three surface sites and from aircraft flights up to 100 km downwind of Mexico City. We will present an initial analysis of the measurements that will quantify the aerosol radiative forcing and its variation downwind of the city during periods favorable for transport over the sampling network. Pacific Northwest National Laboratory's version of WRF-chem, a new fully-coupled meteorology- chemistry-aerosol model based on the chemistry version of the Weather Research and Forecasting (WRF) model will also be used to help interpret the meteorological processes that affect particulate evolution. We will focus on 1) the effect of black carbon and organic carbon on the predicted aerosol radiative forcing and 2) the uncertainties in the emission rates, transport, and transformation of black carbon and other particle types in the region. The model will also be used to quantify the relative roles of anthropogenic sources of black carbon in Mexico City and the numerous biomass burning sources fires that occurred over the central Mexican plateau. Surface and airborne measurements of particulate concentration, size distribution, and optical properties are used to evaluate the model performance.

In many cases, it was co-disposed with EDTA (ethylendiaminetetraacetate), a strong chelating agent that may enhance Pu solubility and thus its mobility. Little is known about the microbial effects on Pu speciation and fate, and the role co- contaminants may play in these reactions. However, in contrast to most other metal ions that reduce to insoluble precipitates, the microbial reduction of Pu(IV) is expected to present products with potentially greater solubility and thus, mobility. Therefore, a comprehensive understanding of the microbial effects on Pu geochemistry is needed particularly to discriminate between Pu solubilization and reduction reactions. We hypothesized that dissimilatory metal- reducing bacteria could reduce Pu(IV) and ultimately increase its solubility. In the experiment presented here, {\it Shewanella oneidensis} MR-1 was able to reduce PuO$_{2}$(am), but not solubilize it; {\it S. oneidensis} MR- 1 and EDTA together were observed to enhance Pu reduction and solubilize it. Ongoing research seeks to identify the speciation of Pu during these reactions, the stability of the equilibrium products, and also strives to identify the location of these reactions (cellular, extracellular).

Previous analyses of surface measurements including solar radiation, sunshine duration, cloud cover, and pan evaporation, showed a decreasing trend in the surface solar radiation, despite a concurrent tendency for more frequent clear sky in the last 50 years. More recent analysis further revealed that much of China has experienced significant decrease in global solar radiation and increase in diffuse solar radiation under cloud-free skies from 1960s to 1990s. These trends are consistent with the increasing aerosol loading from emission of pollutants in China. To further our understanding of aerosol effects, analyses are being performed to investigate observed changes in precipitation characteristics and atmospheric stability. Analysis of long-term precipitation data shows that the frequency and amount of light rain have decreased in the second half of the last century, especially over eastern China where air pollution and aerosol loading are more pronounced. Furthermore, a weekend effect (more/less frequent precipitation during weekend/weekdays), consistent with the weekly cycle of the Air Pollution Index and concentrations of PM, SO2, and NOx, is evident in the daily precipitation record. Trends in atmospheric stability based on temperature sounding data from 1958-2004 are also being analyzed to elucidate possible links between the observed changes in solar radiation, atmospheric stability, precipitation characteristics, and potential indirect effects of increasing aerosol concentrations resulting from the ever-growing population and human activities in China.

Many of these tanks and their associated infrastructure (e.g., pipelines, diversion boxes) have leaked. Some of the leaked waste is projected to have entered the groundwater. The largest known leak occurred from the T-106 Tank in 1973. Most of the contaminants from that leak still reside within the vadose zone beneath the T Tank Farm. To minimize movement of this residual contaminant plume, an interim infiltration barrier will be constructed on the ground surface. This barrier is expected to prevent infiltrating water from reaching the plume and moving it further towards groundwater. An integrated system will be used for vadose zone moisture monitoring, model calibration, performance assessment, and prediction (MCAP). The system is to be broadly- designed so that the data can be used for multiple purposes. In addition to monitoring soil water movement both under the proposed barrier and adjacent to it, the collected data can also be used to characterize vadose zone hydraulic properties and to calibrate a numerical model. The calibrated model can then be used to assess the performance of the infiltration barrier and to predict water flow and contaminant transport under conditions with and/or without a barrier. A MCAP system is being applied to the Hanford's T Tank Farm. Soil water content is to be monitored using both neutron and capacitance probes; soil water pressure and soil temperature will be monitored with heat dissipation sensors; and water flux will be measured using water fluxmeters. These instruments will be installed in direct push probe holes advanced by a hydraulic hammer unit. Excluding neutron probe measurements, all data collection and data transmittal will be sent to an automated central server. This design allows measurements to be taken continually and reduces the need for personnel to enter the farm thereby increasing worker safety. It is expected that the integrated MCAP system will produce a valuable analysis and be cost effective.

However, due to the production of a thick heteropolysaccharide outer layer, M. barkeri usually grows in large aggregates of cells rather than as individual, planktonic cells. Complete disruption of these aggregates and lysis of the released cells presents technical difficulties in ensuring the isolation of intact RNA from the entire population of cells. Initial attempts at isolating RNA from M. barkeri using several standard extraction protocols gave incomplete lysis of cells and resulted in low yields of poor quality RNA. In this study, we tested several chemical and mechanical disruption modifications of standard RNA extraction methods to optimize the extraction efficiency and minimize the number of unlysed cells remaining after extraction. As a further test of the quality of the resulting RNAs, their performance in replicate microarray analyses were determined. The results showed that inclusion of a liquid nitrogen grinding step prior to Trizol extraction, combined with moderate bead beating, yielded the most complete cell lysis, the highest yield of RNA and the most reproducible microarray results for M. barkeri. From these results it is clear that the methods used to isolate RNA can have a significant impact on the variability, trend and, presumably, the accuracy of microarray data. In addition, functional analysis of the microarray results obtained with RNA from the optimized protocol showed that, as expected, the genes involved in methanogenesis were among the most highly expressed genes in M. barkeri.

Models for heterogeneous porous media were generated by using randomly located non-intersecting circular grains of different sizes, and pore scale anisotropy was introduced by randomly inserting non-overlapping particles on either side of the gap between two self-affine fractal curves to create a microfracture. Different fluid wetting behaviors and surface tensions were modeled using pair-wise particle-particle interactions. In simulations of miscible fluid flow, particles with variable, composition dependent, masses and viscosities were used. Artificial surface tension effects were avoided by basing the SPH equations on the particle number density.
