The glass data provide a more accurate estimate of "zero-age" disequilibria for use in external isochron dating than was previously available. Furthermore, plagioclase-glass (super 226) Ra- (super 230) Th disequilibria delimit the degree of initial fractionation of radium from barium during crystal growth, with effective D (sub Ra) /D (sub Ba) approximately 0.25-0.5. These data are inconsistent with the common assumption that D (sub Ra) = D (sub Ba) but are qualitatively consistent with theoretical model predictions that radium and barium should be fractionated during crystallization, with D (sub Ra) /D (sub Ba) approximately 0.2. In more detail, differences between model predictions and data could be explained by an extreme combination of model and data uncertainties, but more likely suggest suppression of efficient fractionation during rapid crystallization. We also assess the extent to which use of barium as an analog for radium would result in underestimating (super 226) Ra- (super 230) Th disequilibria produced during melting. Effects of a lower value of D (sub Ra) on most melting models are small, with a slight increase in the porosity or melt fraction for a given value of (super 226) Ra/ (super 230) Th. The new plagioclase data also indicate that plagioclase accumulation and assimilation in the crustal reservoir would have only a negligible effect on mantle-derived (super 226) Ra- (super 230) Th disequilibria. External isochron ages from U-Th, U-Pa, and Th-Ra data calculated using initial disequilibria from the 1996 sample are concordant, with one exception. Anomalously young ages for off-axis samples most likely reflect volcanism up to 1 km off-axis. Radium ages for near-axis dredge samples for other areas of the North Gorda Ridge generally range from 2000 to 4000 yr, similar to calculated steady-state eruptive periodicity of 3000 yr for this ridge segment. However, comparison of radium excesses for the 1996 eruption and a nearby older lava suggests that recent volcanism at this site occurs with relatively short-lived (0.5 Aa) and with significant interlayer water exchange; and Type 3, essentially non-expandable (0-0.2 Aa) and with little interlayer water exchange. For Type 1, the fully expanded phases have a two-water layer structure, and the phase transition from one layer to two layers as determined by XRD consistently correlates with a significant step in the water sorption isotherm and with changes in the interlayer structure and dynamics as observed by NMR spectroscopy. For Type-2 phases, only one-water layer structures form, and the interlayer anions may undergo dynamical disordering with increasing RH, as observed by NMR. For both Types 1 and 2, the first water layer does not cause significant basal spacing expansion due to occupancy of vacant interstitial sites between the anions by the water molecules. For Type -3 phases, there is little interlayer water sorption because the interlayers are essentially closed due to the small size or planar shape of the anions and their strong electrostatic and hydrogen bonding interaction with hydroxyl layers. RH has no effect on the structural environments and dynamics of the interlayer anions in this group.

Oxygen and C isotope fractionation between calcite or dolomite and evolved CO (sub 2) gas during thermal decarbonation in a 3 bar He pressure environment is very small. The delta (super 13) C and delta (super 18) O values of evolved CO (sub 2) gas are nearly identical to those of the carbonate, very different from the calculated equilibrium Delta (super 18) O (sub calcite-CO2) value of -4 to -5 per mil at 800-900 degrees C or from previous experimental results of decarbonation in vacuum. The kinetic Delta (super 18) O (sub siderite-CO2) values are approximately -2 per mil, whereas Delta (super 13) C (sub siderite-CO2) values increase logarithmically with time, from approximately 1 per mil for the earliest stages of decarbonation to >5 per mil in the final stages. Incomplete siderite decomposition produces both magnetite (delta (super 18) O = 3.5 per mil SMOW) and minor graphite. CO and O (sub 2) were detected during the decarbonation process. The data can be explained by simultaneous oxidation and reduction by the reaction: 6FeCO (sub 3) --> 2Fe (sub 3) O (sub 4) + 2x CO + 4y CO (sub 2) + (6-2x-4y) C + (5-x-4y) O (sub 2) , where x and y are between 0 and 1. Siderite decomposition in the presence of H (sub 2) gas produces wustite and Fe metal in place of oxidized Fe minerals. The experiments in this study are not a perfect analog for possible decarbonation conditions that might have occurred to the carbonates in ALH84001. Nevertheless, the large delta (super 13) C and delta (super 18) O variations observed in ALH84001 (>10 per mil for O) are significantly larger than those expected by thermal decarbonation, suggesting instead a low-temperature mechanism for their formation.

Ages for terraces derived from OSL dates on sand lenses overlying terrace straths agree with dates related to the maximum extent of late Pleistocene moraines. This correlation suggests terrace aggradation is related to deglaciation, supporting a link to glacial activity. Time-related trends in soil development confirm radiometric ages of alluvial terraces and glacial deposits obtained by radiocarbon, luminescence, and magnetostratigraphic methods. Terrace soils show strong trends related to pedogenic accumulation of calcium carbonate and Fe oxides, carbonate morphology, and total profile thickness. We report the first chronology of a sequence of glacial outwash events in the central Pyrenees and adjacent Ebro Basin. We document glacial retreat at approximately 10 ka [5-16 ka (Younger Dryas)], approximately 36 ka [34-46 ka; marine isotope stage 3 (MIS 3)], approximately 53 ka [45-58 ka (MIS 3)], approximately 60 ka [53-84 ka (MIS 4), and approximately 85 ka [75-113 ka (MIS 5b)] with the maximum extent of glaciers in the Pyrenees occurring at nearly equal 60 ka in the Cinca River valley and 85 ka in the Gallego River valley. Our terrace chronology is consistent with millennial-scale vegetation changes in the Mediterranean region, although uncertainties on our luminescence dates prevent exact matching of climatic events. The absence of fluvial terraces of approximately 14 kyr age, and the previously documented absence of large volumes of ice in the Pyrenees during the Last Glacial Maximum (LGM; 18-20 ka) suggest low precipitation in the Pyrenees at that time. Glacial advances and retreats in the Pyrenees Range appear linked to the position of the polar front in the North Atlantic Ocean. The position of the polar front during the YD and MIS 3, 4, and 5b was near its mean position, allowing warm subtropical water to circulate to the northwest of Iberia, resulting in transfer of heat and moisture to the atmosphere in the path of the prevailing westerlies that bring storm tracks across Iberia. The zonal position of the polar front at approximately 43 degrees N during the LGM resulted in an extreme southerly position for the jet stream such that polar conditions prevailed in Iberia while Tropical Depressions delivered enough precipitation to the Sahara to allow expansion of lacustrine deposition.

Many studies have shown that streamline-based simulation models are a computationally simple and accurate numerical solution technique. These approaches gain their efficiency by converting the large three-dimensional transport problem into a series of one-dimensional simulations along streamlines. These models are also efficient because they neglect transverse dispersion, thereby allowing all the streamlines to be decoupled. However, for many reactive transport applications, transverse dispersion is a crucial mechanism for mixing various chemicals. We propose a conceptually straightforward method to incorporate transverse mixing into streamline simulation methods based upon using a first-order mass-transfer approximation to transverse dispersion. We describe some details about the new method and present preliminary results for nonreactive and reactive transport.

We generate a large number of realizations of the log hydraulic conductivity field by first creating binary indicator random fields of two materials and then superposing them with Gaussian random fields, thereby allowing spatial variations of log hydraulic conductivity in each material. For each realization, the steady-state flow equation is solved, a particle is released at a fixed position, and the travel time to some control planes is recorded. The particle's position in the transverse direction is also recorded. We then compute the statistics of particles from all Monte Carlo simulations. We investigate the effect of the contrast of the mean log hydraulic conductivity between two materials and the impact of the degree of heterogeneity on transport statistics. Our results show that, a unimodal distribution of Y always yields a unimodal distribution of travel time tau . However, if the distribution of Y is bimodal, the distribution of the travel time is not always bimodal. The distribution of log travel time log(tau ) is bimodal only if the contrast between two materials is large while the variability of Y in each material is small. In addition, the mean travel time in a bimodal porous medium is slightly smaller than that in an equivalent unimodal porous medium. Furthermore, the transverse spreading increases as the increase of the total variability of Y, and it is larger in a bimodal porous medium than that in a corresponding equivalent unimodal porous medium.

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

This conclusion is supported by the apparent paucity of hydroclastic material in samples recovered from deep submarine environments. Analog molten fuel-coolant interaction (MFCI) experiments, however, demonstrate explosive dynamics for conditions where water is pressurized above its critical pressure before interaction; MFCI theory further indicates this explosive potential. Thermodynamic predictions show that the conversion of thermal to mechanical energy is only high enough to support explosive behavior for a narrow range of water/magma mass ratios. In submarine environments, apparent mass ratios are too high for explosive behavior, but effective mass ratios (those determined from the water and magma directly involved during interaction) depend upon characteristic times, determined by the sound speed of the water and interface geometry. At high pressure, a supercritical fluid film grows at the water/magma contact surface and can become unstable. With instability the film oscillates, rapidly expanding and collapsing, with a periodicity of milliseconds or less. Each film collapse imparts kinetic energy into the magma, causing magma fragmentation, especially where quench contraction has weakened the magma. With fragmentation more magma surface area is exposed to water, and the film growth/collapse process escalates. When perturbed by some external pressure wave, the unstable film is prone to a detonation-like phenomenon that causes rapid, localized vapor expansion even at high ambient pressure.

This general geologic framework, a thick and varied stratigraphic section together with a basin structure, exerts a strong influence on the occurrence, movement, and quality of ground water in the region. The depositional history of the region produced limestone, sandstone and alluvium aquifers separated by mudrock aquitards. This complex stratigraphic sequence and the basin structure result in confined hydraulic conditions. Hydrodynamically, the basin has evolved through the compaction (discharge) stage to the equilibrium (recharge) stage. Recharge occurs where aquifers crop out or subcrop beneath alluvium and colluvium. The rate of recharge varies with aquifer type and landscape setting. Flow direction is generally basinward, controlled by dip. Rates of movement are greatest in the permeable sandstones and limestone. Discharge areas are associated with topographic lows, principally stream valleys. Total-dissolved-solids content of water in the sandstone aquifers varies with associated rock type, grain size of the water-bearing unit, and distance from recharge areas.

It is distinguished by the strikingly white, vertical and horizontal, centimeter- to meter-scale, magmatic veins that cut across the black faces of the edifice. At nearby Tejana Mesa, a latticework of centimeter-scale subvertical veins merges upward into a single 10-m thick white sill that extends some 200 m along the cliff face. El Porticito consists primarily of two basanites. The late basanite has more Al (sub 2) O (sub 3) and less MgO and compatible trace elements, indicating that it is more evolved than the early basanite. Residuals calculated during mass balance modeling of crystal fractionation suggest that the second basanite probably did not evolve from the early basanite. Instead, similar rare earth element concentrations and identical epsilon (sub Nd) (+3.2) suggest that the two basanites evolved from a common mantle parent. Although concentrations are near detection limits, the lower calcium contents of the cores of olivine phenocrysts found in the late basanite suggest that equilibration between olivine cores and surrounding melt occurred at greater depth than in the early basanite. Geochemical modeling, using major and trace element data, suggests that vein magma probably evolved at shallow depth through crystal fractionation from the older, less-evolved basanite. However, the solutions of the models are close enough that the possibility remains that the veins evolved from the later-erupted, less evolved basanite. Veins occur only within the late basanite, except in one small volume at Tejana Mesa where they extend less than a meter into the early basanite. Partially and entirely detached xenoliths of wall rock found in veins are compatible with forceful intrusion of vein magma into its host. The existence of both smooth trajectories and abrupt, right angle changes in vein orientation suggest that vein magma intruded the younger basanite at presently exposed levels while the basanite cooled through the rheological critical melt percentage and behaved as both a ductile and brittle host, depending upon its degree of crystallinity at a particular location.

The Pleistocene stratigraphic section that contains the mandible suggests deposition in a low energy fluvial environment with small channels. The Pleistocene stratigraphic section is interpreted to represent a shallow, sandy, aggrading stream system. Stratigraphic relationships support the inference that the mastodont is a late Pleistocene-age fossil of Mammut americanum. M. americanum is rare in New Mexico and the southwestern United States, especially when compared to the numerous records of mammoths from this region. The Trapped Rock Draw mandible is the sixth record of M. americanum from New Mexico, and the first record from the Colorado Plateau in the northwestern part of the state. Invertebrate faunal analysis of samples collected from the stratigraphic section containing the mandible suggests that paleoenvironmental conditions at the time of the Trapped Rock Draw mastodont were characterized by complex ecosystems and a somewhat cooler and wetter climate than at present, with localized marshy conditions. Absolute age constraints are not currently available for the mastodont specimen, but charcoal samples collected from strata that overlie and underlie the mandible could provide an excellent temporal framework for the Trapped Rock Draw mastodont and the associated late Quaternary stratigraphic section.

In these lowlands systems, tie channels are sinuous but non-meandering channels which connect the main stem river to floodplain lakes. These channels allow the bi-directional transfer of water, sediment, biota, carbon and contaminants between river and lakes. As a primary link between rivers and floodplains, tie channels influence floodplain sedimentation (both the quantity and pattern), hydrology, ecology, geochemistry and stratigraphic evolution of lowland river systems. We have conducted field investigations of tie channels in Papua New Guinea (the Fly River), Louisiana (Raccourci Old River nearly equal 65 km upriver of Baton Rouge) and Alaska (Birch Creek). These field investigations include extensive surveys of both cross and along channel morphological trends, grain size characteristics, water levels and geochronological sampling for optically stimulated luminescence (OSL) dating. In all three systems, both the planform and cross-sectional morphology of the channels show remarkable similarities over scales which range by an order of magnitude. The similarities in channel form suggests a commonality of tie channel morphodynamics across a wide range of scales and hydrological settings. Our results also suggest that size of tie channels and possibly the rates of tie channel development systematically scale to the size of the river system along which they occur. Morphologically, tie channels share many similarities with tidal, submarine and deltaic channels. Determining the hydrodynamics that control the observed tie channel morphologies should provide critical insights into the controls on alluvial channel formation and morphology for a range of settings.

Recent equipment advances have made it possible to determine optically stimulated luminescence (OSL) ages from individual sand-size sediment grains and have facilitated the rapid and convenient collection of the quantities of OSL data required for meaningful statistical analysis. Parallel advances in objective analytical methodologies are drastically improving the accuracy of OSL dating, particularly for youthful fluvial sediments. In this investigation we have used single-grain OSL to date sediments deposited by an unaltered tie channel in the lower Mississippi River floodplain approximately 40 miles north of Baton Rouge LA. Floodplain tie channels link lowland rivers to floodplain lakes, commonly oxbow lakes. This "tie" allows the exchange of water, sediment, nutrients, contaminants and biota between rivers and floodplains. While common throughout the world, documentation of tie channel dynamics and evolution is almost entirely lacking in the geological literature. Single-grain OSL geochronology allowed us to examine the rate of advancement of tie channel deposits into the "Raccourci-Old River" oxbow lake and infer vertical accretion rates along the banks of the channel itself. This presentation will focus on the experimental and analytical methods utilized, thereby emphasizing the latest advances in OSL dating. All sediments in this study were deposited after A.D. 1850, so the results demonstrate the applicability of single-grain OSL dating to youthful sediments and highlight the potential of the technique to provide temporal constraints for recent sediment transport studies.

A hallmark of these signaling reactions is the reversible nucleation of multicomponent complexes, which typically begin to assemble when ligand-receptor binding allows an enzyme, often a kinase, to create docking sites for signaling molecules through chemical modifications, such as tyrosine phosphorylation. One function of such docking sites is the co-localization of enzymes with their substrates, which can enhance both enzyme activity and specificity. The directed assembly of complexes can also influence the sensitivity of cellular responses to ligand-receptor binding kinetics and determine whether a cellular response is up- or downregulated in response to a ligand stimulus. The full functional implications of ligand-stimulated complex formation are difficult to discern intuitively. Complex formation is governed by conditional interactions among multivalent signaling molecules and influenced by quantitative properties of both the components in a system and the system itself. Even a simple list of the complexes that can potentially form in response to a ligand stimulus is problematic because of the number of ways signaling molecules can be modified and combined. Here, we review the role of multicomponent complexes in signal transduction and advocate the use of mathematical models that incorporate detail at the level of molecular domains to study this important aspect of cellular signaling.

Often alloyed with other metals such as copper, beryllium is a key component of materials used in the aerospace and electronics industries. Beryllium has a small neutron cross-section, which makes it useful in the production of nuclear weapons and in sealed neutron sources. Unfortunately, beryllium is one of the most toxic elements in the periodic table. It is responsible for the often-fatal lung disease, Chronic Beryllium Disease (CBD) or berylliosis, and is listed as a Class A EPA carcinogen. Coal-fired power plants, industrial manufacturing and nuclear weapons production and disposal operations have released beryllium to the environment. This contamination has the potential to expose workers and the public to beryllium. Despite the increasing use of beryllium in industry, there is surprisingly little published information about beryllium fate and transport in the environment. This information is crucial for the development of strategies that limit worker and public exposure. This review summarizes the current understanding of beryllium health hazards, current regulatory mandates, environmental chemistry, geochemistry and environmental contamination.

Specifically, the performance of an aqueous modified Fenton reagent is examined. A modified Fenton reagent formulation of cupric chloride, ascorbic acid, and sodium chloride is shown to be an effective sporicide under aerobic conditions. The traditional Fenton reaction involves the conversion of hydrogen peroxide to hydroxyl radical by aqueous ionic catalysts such as the transition metal ions. Our modified Fenton reaction involves the conversion of aqueous dissolved oxygen to hydrogen peroxide by an ionic catalyst (Cu super(2+)) and then subsequent conversion to hydroxyl radicals. Results are given for the modified Fenton reagent deactivating spores of Bacillus globigii. A biocidal mechanism is proposed that is consistent with our experimental results and independently derived information found in the literature. This mechanism requires diffusion of relatively benign species into the interior of the spore, where dissolved O sub(2) is then converted through a series of reactions which ultimately produce hydroxyl radicals that perform the killing action.

Here we compare wind erosion and transport field measurements with water erosion and transport from rainfall-simulation for three different semi- arid ecosystems: a shrubland near Carlsbad, New Mexico; a grassland near Denver, Colorado; and a forest near Los Alamos, New Mexico. In addition to comparing erosion loss from an area, we propose a framework for comparing horizontal mass transport of wind- and water-driven materials as a metric for local soil redistribution. Median erosion rates from wind for vertical mass flux measurements (g m super(-2) d super(-1)) were 1.5 × 10 super(-2) for the shrubland, 8.3 × 10 super(-3) for the grassland, and 9.1 × 10 super(-3) for the forest. Wind-driven transport from horizontal mass flux measurements was greatest in the shrubland (15.0 g m super(-2) d super(-1)) followed by the grassland (1.5 g m super(-2) d super(-1)) and the forest sites (0.17 g m super(-2) d super(-1)). Annual projections accounting for longer-term site meteorology suggest that wind erosion exceeds water erosion at the shrubland by c. 33 times and by c. five times at the forest, but not the grassland site, where the high clay content of the soils contributed to greater amounts of water erosion: water erosion exceeded wind erosion by about three times. Horizontal transport by wind was greater than that by water for all three systems, overwhelmingly so in the shrubland (factor of c. 2200). Our results, which include some of the only wind erosion measurements to date for semi-arid grasslands and forests, provide a basis for hypothesizing trends in wind and water erosion among ecosystems, highlight the importance of wind erosion and transport in semi-arid ecosystems, and have implications for land surface geomorphology, contaminant transport, and ecosystem biogeochemistry.

The SAGE code is a compressible Eulerian hydrodynamics code using continuous adaptive mesh refinement for following discontinuities with a fine grid while treating the bulk of the simulation more coarsely. We have used realistic equations of state for the atmosphere, sea water, the oceanic crust, and the mantle. In two dimensions, we simulated asteroid impactors moving at 20 km/s vertically through an exponential atmosphere into a 5 km deep ocean. The impactors were composed of mantle material (3.32 g/cc) or iron (7.8 g/cc) with diameters from 250m to 10 km. In our three-dimensional runs we simulated asteroids of 1 km diameter composed of iron moving at 20 km/s at angles of 45 and 60 degrees from the vertical. All impacts, including the oblique ones, produce a large underwater cavities with nearly vertical walls followed by a collapse starting from the bottom and subsequent vertical jetting. Substantial amounts of water are vaporized and lofted high into the atmosphere. In the larger impacts, significant amounts of crustal and even mantle material are lofted as well. Tsunamis up to a kilometer in initial height are generated by the collapse of the vertical jet. These waves are initially complex in form, and interact strongly with shocks propagating through the water and the crust. The tsunami waves are followed out to 100 km from the point of impact. Their periods and wavelengths show them to be intermediate type waves, and not (in general) shallow-water waves. At great distances, the waves decay as the inverse of the distance from the impact point, ignoring sea-floor topography. For all impactors smaller than about 2 km diameter, the impacting body is highly fragmented and its remains lofted into the stratosphere with the water vapor and crustal material, hence very little trace of the impacting body should be found for most oceanic impacts. In the oblique impacts, the initial asymmetry of the transient crater and crown does not persist beyond a tsunami propagation length of 50 km.

Independent knowledge concerning historical pollution events and super(137)Cs fall-out profiles has allowed a critical evaluation of the CRS, CIC and CF-CS models for the super(210)Pb age interpretation. Resulting ages for the three models suggest that, in this case, the CIC model gives the most accurate interpretation of historical pollution events and atmospheric lead fall-out. The super(210)Pb water-sediment flux was estimated at 141-1158 Bq.m super(-2).yr super(-1) for one site and 62-106 Bq.m super(-2).yr super(-1) at the other site, during the last century. The large difference illustrates that sediment focusing was important on a small spatial scale (10 m). The direction of focusing correlates with the predominant wind direction. Maximum atmospheric lead deposition rates were found to be 1.63 plus or minus 0.59 g.m super(-2).yr super(-1) around 1968 AD, which is 2 orders of magnitude larger than the Belgian average in 1980 AD, and 5 orders larger than Holocene atmospheric lead deposition.

Other studies have shown that some kaolinites contain the lowest-defect material in the coarsest size fractions whereas others contain the lowest-defect kaolinite in the finest fractions. In an attempt to clarify possible mechanisms for producing such kaolinite samples, we have used powder X-ray diffraction to study the effects of mechanical grinding on the nature of layer stacking in the <40 mu m fraction of the American Petroleum Institute kaolinite standard no. 9 from Mesa Alta, New Mexico. This material is relatively rich in a low-defect kaolinite. Hand grinding for 10 min plus grinding under acetone for up to an additional 34 min in an automatic agate grinder produced significant changes in its diffraction pattern. However, further dry grinding in a ball mill for 10 min produced material that was almost totally disordered, based on measures such as the Hinkley index. The diffraction patterns of the wet-ground materials showed evidence of increasing disorder that could be modeled best as a physical mixture of low- and high-defect material, consistent with a physical mixture of the original ordered phase with varying amounts of a highly disordered material. Disorder in the high-defect kaolinite is caused by the interstratification of normal kaolinite layers with their enantiomorphs. Contrary to expectations, grinding of kaolinite does not produce a progressive increase in disorder for all of the crystallites present in a sample. Instead, grinding apparently creates increased amounts of a disordered kaolinite that coexist with relatively unaffected material. There is no evidence for the occurrence of an intermediate disordered phase. Contrary to previous reports, disorder caused by physical stress does not include random layer displacements of + or -b/3.

I modeled a suite of source and path parameters and measured different L (sub g) amplitudes including root-mean-square (rms), peak-to-peak, third-peak (Nuttli, 1980; Patton, 2001), envelope-peak, and spectral amplitudes for analysis. The main result of this investigation is that the estimation of L (sub g) spreading rates from the rms amplitudes and from the spectral amplitudes yielded the most reliable estimates that are basically independent of almost all the source and path variables within the parameter ranges that I simulated. I obtained a spreading rate of Delta (super -1.0) for the rms amplitude and a rate of Delta (super -0.5) for the spectral amplitude across the frequency band of the data. The relationship between the two spreading-rate estimates is consistent with Parseval's theorem. Spreading-rate estimates from other amplitude measurements show larger variations with the variation of source and path parameters. These variations suggest that the behavior L (sub g) peak amplitudes might be more complex than that of a single-mode Airy phase. The decay of the third-peak amplitudes appears to be less rapid than the decay of the peak-to-peak and envelope-peak amplitudes. There are no systematic changes in the spreading rates due to the variation of variables such as velocity model, source depth, and source mechanism. The introduction of a gradient zone at the crust-mantle boundary and the earth-flattening transformation did not change the spreading rates significantly, at least not beyond certain source-receiver distances. The most important variable affecting the L (sub g) spreading appears to be the closeness of the source to major velocity discontinuities in the velocity models.

At long periods (0.01-0.1 Hz), typical vertical noise levels are approximately 12 dB higher than the nearby Global Seismic Network (GSN) borehole station ANMO, but horizontal power spectral density (PSD) noise levels are approximately 30 dB higher. Long-period noise levels exhibit essentially no spatial correlation along the LA RISTRA transect, indicating that local thermal or atmosphere-driven local slab tilt is the dominant source of noise in this band. Between 0.1 and 0.3 Hz, typical noise levels are dominated by naturally occurring microseismic noise and are essentially identical to those observed at ANMO. At short periods, 0.3-8 Hz, typical noise levels along the network exceed ANMO levels by approximately 15 dB, with the highest levels corresponding to proximity to cultural noise sources. No significant day/night variations were observed in the microseismic band; however, both low-and high-frequency noise levels show an increase of up to 8 dB in median midday versus midnight noise levels. We find that the major shortcomings of these shallow PASSCAL style temporary vaults relative to a GSN-style borehole installation are increased susceptibility to long-period horizontal (> or =20 sec) noise and to surface noise sources above approximately 2 Hz. Although the high-frequency near-surface noise field is unavoidable in shallow vaults, we suggest that increased understanding and mitigation of local tilt effects in shallow vaults offers the possibility of significantly improving the long-period noise environment.

Both engineered and administrative controls are used to mitigate hazards inherent in these activities. Nuclear facilities have engineered safety systems that are extensively evaluated and documented, and are monitored regularly for operability and performance. Personnel undergo comprehensive training, including annual recertification of their operations. They must thoroughly understand the hazards involved in their work and the controls that are in place to mitigate those hazards. A series of hazard-control plans and work instructions are used to define and authorize the work that is done. Primary hazards associated with chemicals and radioactive materials are well controlled with minimal risk to the workforce and public. The majority of injuries are physical or ergonomic in nature. In an effort to increase safety awareness and to decrease accidents and incidents, a program focusing on the identification and elimination of unsafe behaviours was initiated. Workers are trained on how to conduct safety observations and given guidance on specific behaviours to note. Observations are structured to have minimal impact upon workload and are shared by the entire work force. This program has effectively decreased a low accident rate and will make long-term sustainability possible. JF - TOPICAL ISSUES IN NUCLEAR SAFETY.

The cloned and sequenced repeat motifs include a triplet repeat of (AAT) sub(n), two tetranucleotide repeats of (GATA) sub(n), a tetranucleotide repeat of (ATCC) sub(n), a compound repeat of (GA) sub(n)(GATA) sub(n) and the two pentanucleotide repeats (AGAAT) sub(n) and (ATTTT) sub(n). The microsatellites described represent six presumably independent loci with the two pentanucleotide repeats having originated from a single cosmid. Primer pairs allow locus-specific amplification of each marker from Mexican spotted owl genomic DNA.

AN - 72630665; 12403618 AB - An interhelical distance has been precisely measured by REDOR solid-state NMR spectroscopy in the transmembrane tetrameric bundle of M2-TMP, from the M2 proton channel of the influenza A viral coat. The high-resolution structure of the helical backbone has been determined using orientational restraints from uniformly aligned peptide preparations in hydrated dimyristoylphosphatidylcholine bilayers. Here, the distance between (15)N(pi) labeled His37 and (13)C(gamma) labeled Trp41 is determined to be less than 3.9 A. Such a short distance, in combination with the known tilt and rotational orientation of the individual helices, permits not only a determination of which specific side chain pairings give rise to the interaction, but also the side chain torsion angles and restraints for the tetrameric bundle can also be characterized. The resulting proton channel structure is validated in a variety of ways. Both histidine and tryptophan side chains are oriented in toward the pore where they can play a significant functional role. The channel appears to be closed by the proximity of the four indoles consistent with electrophysiology and mutagenesis studies of the intact protein at pH 7.0 and above. The pore maintains its integrity to the N terminal side of the membrane, and at the same time, a cavity is generated that appears adequate for binding amantadine. Finally, the observation of a 2 kHz coupling in the PISEMA spectrum of (15)N(pi)His37 validates the orientation of the His37 side chain based on the observed REDOR distance.

Such an approach is essential in mantle circulation models, where we seek to constrain an unknown initial condition some time in the past, and thus cannot hope to use first-principles convection calculations to infer the flow history of the mantle. One of the most important observables for mantle-flow history comes from models of Mesozoic and Cenozoic plate motion that provide constraints not only on the surface velocity of the mantle but also on the evolution of internal mantle-buoyancy forces due to subducted oceanic slabs. Here we present five mantle circulation models with an assimilated plate-motion history spanning the past 120 Myr, a time period for which reliable plate-motion reconstructions are available. All models agree well with upper- and mid-mantle heterogeneity imaged by seismic tomography. A simple standard model of whole-mantle convection, including a factor 40 viscosity increase from the upper to the lower mantle and predominantly internal heat generation, reveals downwellings related to Farallon and Tethys subduction. Adding 35% bottom heating from the core has the predictable effect of producing prominent high-temperature anomalies and a strong thermal boundary layer at the base of the mantle. Significantly delaying mantle flow through the transition zone either by modelling the dynamic effects of an endothermic phase reaction or by including a steep, factor 100, viscosity rise from the upper to the lower mantle results in substantial transition-zone heterogeneity, enhanced by the effects of trench migration implicit in the assimilated plate-motion history. An expected result is the failure to account for heterogeneity structure in the deepest mantle below 1500 km, which is influenced by Jurassic plate motions and thus cannot be modelled from sequential assimilation of plate motion histories limited in age to the Cretaceous. This result implies that sequential assimilation of past plate-motion models is ineffective in studying the temporal evolution of core-mantle-boundary heterogeneity, and that a method for extrapolating present-day information backwards in time is required. For short time periods (of the order of perhaps a few tens of Myr) such a method exists in the form of crude "backward" convection calculations. For longer time periods (of the order of a mantle overturn), a rigorous approach to extrapolating information back in time exists in the form of iterative nonlinear optimization methods that carry assimilated information into the past through the use of an adjoint mantle convection model.

Since the method is implicit, and therefore unconditionally stable, time steps may be used that result in both gravity wave Courant-Friedrichs-Lewy (CFL) numbers and advection CFL numbers being larger than one. By nonlinearly consistent it is meant that all of the unknown variables appear at the same time level in the equations and are solved for simultaneously in an iterative manner (i.e., no splitting errors in time). The INC method is compared to a more traditional semi-implicit method for stepping over the gravity wave stability constraint. Results are presented that show that the second-order-in-time INC method can maintain a high level of accuracy if the dynamical timescale of the system is resolved by the time step. To investigate this difference in temporal integration accuracy between the nonlinearly consistent method and the semi-implicit method an approximate modified equation analysis was performed. The INC solution technique employed is the Jacobian-free Newton-Krylov (JFNK) method. Preconditioning of the JFNK method is achieved via a semi-implicit solution method. The height matrix from the semi-implicit algorithm is solved using a multigrid linear solver to provide efficiency and scalability.

Distinguishing between the effect of melting processes and variable source compositions on measured disequilibria ( (super 238) U- (super 230) Th- (super 226) Ra and (super 235) U- (super 231) Pa) requires measurement of the radiogenic isotopes Hf, Nd, Sr, and Pb. Here, we report measurements of (super 238) U- (super 230) Th- (super 226) Ra and (super 235) U- (super 231) Pa disequilibria; Hf, Nd, Sr, and Pb isotopic; and major and trace element compositions for a suite of 20 young midocean ridge basalts from the East Pacific Rise axis between 9 degrees 28' and 9 degrees 52'N. All of the samples were collected within the axial summit trough using the submersible Alvin. The geological setting and observational data collected during sampling operations indicate that all the rocks are likely to have been erupted from 1991 to 1992 or within a few decades of that time. In these samples, (super 230) Th excesses and (super 226) Ra excesses are variable and inversely correlated. Because the eruption ages of the samples are much less than the half-life of (super 226) Ra, this inverse correlation between (super 230) Th and (super 226) Ra excesses can be considered a primary feature of these lavas. For the lava suite analyzed in this study, (super 226) Ra and (super 230) Th excesses also vary with lava composition: (super 226) Ra excesses are negatively correlated with Na (sub 8) and La/Yb and positively correlated with Mg#. Conversely, (super 230) Th excesses are positively correlated with Na (sub 8) and La/Yb and negatively correlated with Mg#. Th/U, (super 230) Th/ (super 232) Th, and (super 230) Th excesses are also variable and correlated to one another. (super 231) Pa excesses are large but relatively constant and independent of Mg#, La/Yb, Th/U, and Na (sub 8) . The isotope ratios (super 143) Nd/ (super 144) Nd, (super 176) Hf/ (super 177) Hf, (super 87) Sr/ (super 86) Sr, and (super 208) Pb/ (super 206) Pb are constant within analytical uncertainty, indicating that they were derived from a common source. The source is homogeneous with respect to parent/daughter ratios Lu/Hf, Sm/Nd, Rb/Sr, and Th/U; therefore, the measured variations of Th/U, (super 230) Th, and (super 226) Ra excesses and major and trace element compositions in these samples are best explained by polybaric melting of a homogeneous source, not by mixing of compositionally distinct sources.

The origin and transport of spring waters from which travertines precipitate are elucidated by chemical and isotopic studies of the travertines and associated thermal springs and gas vents. There are consistent differences in the geochemical and isotopic signatures of thermal spring waters, gas vents and present and fossil travertines between east and west of the Tiber Valley. West of the Tiber Valley, delta (super 13) C of CO (sub 2) discharged from gas vents and delta (super 13) C of fossil travertines are higher than those to the east. To the west the travertines have higher strontium contents, and gases emitted from vents have higher (super 3) He/ (super 4) He ratios and lower N (sub 2) contents, than to the east. Fossil travertines to the west have characteristics typical of thermogene (thermal spring) origin, whereas those to the east have meteogene (low-temperature) characteristics (including abundant plant casts and organic impurities). The regional geochemical differences in travertines and fluid compositions across the Tiber Valley are interpreted with a model of regional fluid flow. The regional Mesozoic limestone aquifer is recharged in the main axis of the Apennine chain, and the groundwater flows westward and is discharged at springs. The travertine-precipitating waters east of the Tiber Valley have shallower flow paths than those to the west. Because of the comparatively short fluid flow paths and low (normal) heat flow, the groundwaters to the east of the Tiber Valley are cold and have CO (sub 2) isotopic signatures, indicating a significant biogenic contribution acquired from soils in the recharge area and limited deeply derived CO (sub 2) . In contrast, spring waters west of the Tiber Valley have been conductively heated during transit in these high heat-flow areas and have incorporated a comparatively large quantity of CO (sub 2) derived from decarbonation of limestone. The elevated strontium content of the thermal spring water west of the Tiber Valley is attributed to deep circulation and dissolution of a Triassic evaporite unit that is stratigraphically beneath the Mesozoic limestone. U-series age dates of fossil travertines indicate three main periods of travertine formation (ka): 220-240, 120-140 and 60-70. Based on the regional flow model correlating travertine deposition at thermal springs and precipitation in the recharge area, we suggest that pluvial activity was enhanced during these periods. Our study suggests that travertines preserve a valuable record of paleofluid composition and paleoprecipitation and are thus useful for reconstructing paleohydrology and paleoclimate.

The combination of such understanding with advanced flow and transport modeling establishes the link between cause and effect, thereby, directing operators to optimal design and construction of new heaps. Modeling of flow and transport in heaps could also point to a unique change in application method or rate that would maximize leaching enhancement of an existing heap under existing situation and leaching history. The use of such a model is cost effective in that it can simulate multiple scenarios of alternative leaching enhancement methods. By simulating a large number of irrigation scenarios, such a model can point to the optimal and/or the most promising alternatives for a particular heap. The authors' simulations concentrate on the effects of changes in application rates and heap design on changes in flow paths and enhanced leaching recovery. Based on such simulations, an intelligent control agent, such as Multiple Resolution Decision-Support System (MRDS) (Meystel and Albus, 2002), could build a new representation of the complex heap-leaching system. And, by learning from historical data and current information, it could provide optimal management of heap leaching and heap decommissioning.

We present an alternative hypothesis: convection-driven plate motions are intrinsically unstable due to a buoyant instability that develops as a result of the influence of plates on an internally heated mantle. This instability, which has not been described before, is responsible for episodic reorganizations of plate motion. Numerical mantle convection experiments demonstrate that high-Rayleigh number convection with internal heating and surface plates is sufficient to induce plate reorganization events, changes in plate boundary forces, or plate geometry, are not required.

Chaco Wash, the principle stream transversing the park, has experienced several episodes of incision and filling during the Holocene. Presently, park custodians are concerned that these ongoing processes, particularly arroyo wall retreat may threaten several of the "Great House" ruins found within Chaco Canyon. The primary objective of this investigation is to develop a geochronology of late Holocene stream dynamics for the contemporary Chaco arroyo and the inner channel of Chaco Wash. To achieve this goal, several optically-stimulated luminescence (OSL) dating techniques have been applied to sediment samples from the wash. The sediments collected represent modern (April 2000) and late Chacoan aged (950-1100 yrs. BP) deposits as well as a set of samples without age control, from an inset terrace exposed in the modern arroyo wall, believed to be intermediate in age. The OSL techniques employed included multiple aliquot additive dose measurements using infrared-OSL on polymineral fine-grains (IRSL MAAD), blue-OSL on single aliquots of quartz sand (OSL SAR), and single-grain green laser luminescence (SGLL) on quartz sand. These last two methods, OSL SAR and SGLL, allow hundreds of age estimates to be made from a single sample, thereby facilitating the use of advanced analytical techniques. OSL ages for the modern sediments were largely over-estimates. However, stream flow data indicates that the April 2000 runoff event peaked at 8:30 AM. Given the origin of the event, high in the watershed, it can be inferred that most of the transport period was at night. Also, streams in the region carry exceedingly high sediment loads (5-40% by volume). Successful OSL dating is unlikely for such short duration, high turbidity, nighttime events. OSL ages for the late Chacoan aged samples were consistent with radiocarbon and other age controls within error limits, independent of the OSL technique used, suggesting less extreme pre-modern transport scenarios. Results from OSL analysis and dating of the inset terrace deposits highlight the potential of advanced OSL tools, such as SAR/SGLL and dose distribution analysis.

These studies are required because three episodes of small-volume, alkalic basaltic volcanism have occurred within 50 km of Yucca Mountain during the Quaternary. Probabilistic hazard estimates for the proposed repository depend on the recurrence rate and spatial distribution of past episodes of volcanism in the region. Several independent research groups have published estimates of the annual probability of a future volcanic disruption of the proposed repository, most of which fall in the range of 10 (super -7) to 10 (super -9) per year; similar conclusions were reached through an extensive expert elicitation sponsored by the Department of Energy in 1995-1996. The estimated probability values are dominated by a regional recurrence rate of 10 (super -5) to 10 (super -6) volcanic events per year (equating to recurrence intervals of several hundred thousand years). The recurrence rate, as well as the spatial density of volcanoes, is low compared to most other basaltic volcanic fields in the western United States, factors that may be related to both the tectonic history of the region and a lithospheric mantle source that is relatively cold and not prone to melting. The link between volcanism and tectonism in the Yucca Mountain region is not well understood beyond a general association between volcanism and regional extension, although areas of locally high extension within the region may control the location of some volcanoes. Recently, new geologic data or hypotheses have emerged that could potentially increase past estimates of the recurrence rate, and thus the probability of repository disruption. These are (1) hypothesized episodes of anomalously high strain rate, (2) hypothesized presence of a regional mantle hotspot, and (3) new aeromagnetic data suggesting as many as twelve previously unrecognized volcanoes buried in alluvial-filled basins near Yucca Mountain.

This study is to determine the effects on the critical population from erupted tephra carried along or through the Fortymile Wash drainage system, which is main drainage for the eastern slope of the Yucca Mountain area. The critical population (REMI) lives at a distance of approximately 20 km from the repository, on the alluvial fan/delta of the Fortymile Wash. Our study will evaluate ash redistribution resulting from wind or water erosion in order to determine the impact to the dose that the critical population would experience. In order to predict the dose amount we will determine the nature of ash redistribution area and how the ash is diluted through the drainage system. We purpose to calculate the volume of material that has been deposited within the past 50 years using Cesium-137, a bomb produced tracer, to determine the erosional and depositional patterns around Yucca Mountain. Most Cesium-137 studies to date have only covered a small (1500 square km and require more than 200 samples. The Lathrop Wells volcanic cone, located 12 km south of Yucca Mountain, erupted 70,000 years ago and produced an extensive tephra sheet. This tephra sheet will be studied as an analog to the possible eruption through the repository to determine the nature of tephra dilution in drainages west and south of the cone. Samples have been collected at 100-ft intervals along the tephra sheet and along the ash filled drainage systems. Stratigraphy of the pits will be mapped and sampled to establish a transect along which ash is diluted from its source over a distance of >2 km. The values obtained from the ash dilution study, applying the scaling factor for the Fortymile wash system, will be used to calculate the amount of contaminated ash that would reach the critical population and impact the calculation of the dose.

Today, they have to perform under higher visibility by stakeholders. Their activities are much more scrutinized in regards to economic pressure, litigation support and regulatory compliance than in the past. Stakeholders are beginning to want to evaluate raw data, rather than just examine summaries in final reports. They also need assurance, partly because of legal reasons, that data control and quality procedures were followed. In order to effectively respond to these problems, Geoscientists are now faced with the challenge of cost effectively collecting, managing, analyzing, and synthesizing multidisciplinary and complex information. This information must be processed and disseminated in a way that allows stakeholders to make informed and rational decisions. The new paradigm is clear--Stakeholders needs must be better met, and the systems used to store and generate information must meet these needs. This paper addresses the challenges and implications of this new paradigm on geosciences information management in the 21st Century. It concludes with a case study for a successful implementation of the new paradigm in an Environmental Restoration Project at the Los Alamos National Laboratory operated by the Department of Energy.

Experiments were conducted in a flexible cell hydrothermal apparatus to determine the extent of fluid-rock reactions, in addition to carbonate mineral precipitation, that may occur in a brine aquifer-aquitard system simulated as a saline aquifer storage scenario. The aquifer is a synthetic arkose (microcline (Or91-97)+oligoclase (An17-21)+quartz+biotite), the aquitard is argillaceous shale, and the fluid is 5.5 molal NaCl brine. The system was held at 200 C and 200 bars for 32 days (772 hours) to approach steady state, then injected with carbon dioxide and allowed to react for an additional 45 days (1079 hours). In a separate experiment at 200 C and 200 bars, the system was allowed to react for 77 days (1845 hours) without injection of carbon dioxide. Brine-rock reaction decreases pH from 8 to approximately 5.9 in both experiments. In the brine-rock-carbon dioxide experiment, injection of carbon dioxide produces a pH drop (possibly below 4, based on calculation) followed by rebound to approximately 6.6 as the minerals react with carbon dioxide-charged brine. Concentrations of Si and Mg in the brine increase following injection of carbon dioxide. In addition to carbonate mineral precipitation, silicate minerals (quartz, oligoclase, microcline and biotite) in the aquifer and aquitard display textures (etch pits, mineralization) indicating significant reactions. A pressure decrease of 23 bars occurred in the experimental cell over a 3-day period following carbon dioxide injection. Pressure was stable afterwards. The pressure decrease is interpreted as consumption of supercritical carbon dioxide by dissolution in brine and subsequent precipitation as carbonate mineral. The experimental reactions provide initial constraints on reactions and reaction rates that can impact the containment interface in moderate temperature brine aquifer systems with potential for carbon sequestration.

Henry's Law fractionation, vapor phase diffusion as a function of water content, and surface boundary layer effects are simulated. Topography, geology, and anthropogenic factors (i.e. asphalt) are included. The model results are compared to an extensive data set from the site that includes over 100 quarterly vapor sampling ports. Correlation between model and data is quite good (r2 = 0.973) showing that the conceptual model of transport is adequate to explain the behavior of the subsurface VOC plume. The modeling indicates that the plume has reached a near-steady state with respect to the atmospheric boundary and should not grow significantly through time. This result has implications for the style of remediation that will be implemented at the site, allowing less drastic measures (i.e. source removal) to be taken. Natural attenuation with the addition of passive vapor venting is likely to be the most viable alternative for site remediation.

Because of its high affinity for U and other radionuclides and its thermal annealing behavior, there is also great interest in apatite as a solid nuclear-waste form and an engineered contaminant barrier. Fundamental to our understanding of uranium retention and release by apatite are crystal chemical parameters such as site occupancy, oxidation state, and structural distortions created by this substituent. Despite the interest in U in apatite, the basic crystal chemistry of its substitution in the structure is still unknown. We present the first direct evidence of the site of incorporation and the response of the structure to U(VI). X-ray absorption spectroscopy was used to determine the local structure of U(VI) within synthetic fluorapatite at a concentration of 2.3 wt.%. Extended X-ray absorption fine structure results indicates that U(VI) substitutes into the Ca1 site. To accommodate this substitution the apatite structure significantly distorts such that the Ca1 site approximates octahedral coordination, with 6 uniform U-O distances of 2.06 Aa. An unusual X-ray adsorption edge structure, with two inflection points separated by 8.4 eV, and optical emission spectra indicate uranium 6d orbital crystal field splitting. These results indicate that significant amounts of U(VI) can be accommodated in the apatite structure but with an unexpected coordination, which may bear on the ultimate development of apatite-hosted nuclear-waste forms.

The fire increased observed flood magnitudes and hillslope erosion rates by one to two orders of magnitude above pre-fire conditions. Flooding increased scour and deposition in canyon channels that had been relatively stable over the past 50 years. A set of modeling activities were undertaken to predict the potential impacts of large and small rain events on human health, contaminant migration, LANL facilities and infra-structure. Channel sediment and contaminant transport predictions were made using the HEC and HEC6T suite of models. HEC6T, a one-dimensional sediment transport model, was coupled to a contaminant model to predict potential redistribution and offsite transport of contaminated hillslope and floodplain sediments. HEC6T predictions were tested and calibrated against observations from a large flood in Pueblo Canyon. This event occurred on July 2, 2001, about a year after the Cerro Grande fire, had a peak of about 1440 cfs and is the flood of record for the canyon. The headwaters of Pueblo Canyon were severely burned in the Cerro Grande fire. High-resolution Airborne Laser Scanning (ALS) topographic data were collected before and after the flood, and form the backbone of our model validation/testing process. The ALS data were validated with field cross-sections. Difference maps of 1 foot DEM's derived from the ALS data were used to quantify the spatial distribution of channel and floodplain scour and deposition throughout the canyon. The ALS derived sediment volume changes were compared to predicted volume changes, and show good agreement between observed and predicted regions of scour and deposition along a 3 mile stretch of channel. The comparison suggests that the HEC6T model may be a reasonable model for assessing the impacts of floods in this and other canyons in the area. On-going work aims to assess the impact of post-fire recovery on floods and sediment mobility, and to quantify uncertainty in the model predictions.

Although geologic complexity in the basin is well documented, the degree to which geologic features control groundwater flow is unclear. We present an analysis ranking alternative geologic models based on their ability to represent existing groundwater data and associated impacts on groundwater transport predictions. The geometry of key geologic features, with associated uncertainty, is expressed via alternative 3-D geologic models. Using non-linear optimization, we estimate medium properties for each of alternative geologic models based on the large dataset of stream-baseflow flux and spatially- and temporally-varying water-level measurements throughout the basin. Using statistical methods, we rank the models based on their ability to represent the measurements and to impact groundwater transport predictions. In areas where water level data are sufficiently dense, this process objectively identifies those geologic features that have hydrologic significance and those features that are clearly "flow neutral". It also identifies the hydrostratigraphic structures which are import to our transport predictions.

A laboratory-scale crushed-tuff hydrothermal column test was used to investigate the tuff as a potential construction material within a nuclear-waste repository. Results of similar column tests have been cited as indications that silica deposition would plug the rock fractures above a repository and create unfavorable drainage conditions. Data from field and laboratory tests are used here to predict the magnitude of fracture sealing. For the crushed-tuff column test, a one-meter-high column was packed with crushed tuff to a porosity of about 50%. Water filling the lowermost 10 cm of the column was boiled and the vapor condensed at the top of the column, percolating down to the boiling zone. After 100 days, intergranular pore space in the saturated portion of the column was almost filled with amorphous silica. The Drift Scale Test at Yucca Mountain is a heating test in the unsaturated zone. It consists of a four-year heating phase, now complete, followed by a four-year cooling phase. Heaters in a 60-m-long drift and in the adjacent rock have heated the drift walls to 200 degrees C. As the rock was heated, fluids naturally present in the rock migrated away from the heat sources. A boiling zone now separates an inner dry-out zone from an outer condensation zone. A heat-pipe region exists in the outer margin of the boiling zone above the heated drift. Amorphous silica coatings up to a few micrometers thick were deposited in this region. Deposits were observed in less than 10% of the fractures in the heat pipe region. Drift-scale test results yield a silica deposition rate of about 250 mu m/1000 years in 10% of the fractures in the heat-pipe region. We did not calculate deposition rates from our column test, but a rate of 9.1 mm/1000 years in all fractures of the heat-pipe region is predicted by Sun and Rimstidt (2002) from the results of a similar test. We believe the rate based on field-test observations is a better prediction because the field test more closely resembles the expected environment in a repository. Rates based on column-test results may be reasonable for local zones of preferred fluid flow.

Busted Butte Phase 2 consisted of a 10 mX10 mX7 m test block. From July 1988 through October 2000, complex tracer mixtures were injected continuously at 77 discrete points located along eight parallel 10-m boreholes arranged in two horizontal planes. In August 1999, iodide was added to the tracer mixture to explore the effects of initial hydraulic transients. During the course of the experiment, porewater samples were collected at regular intervals using sorbing-paper collection pads, emplaced into fifteen horizontal and inclined 10-m collection boreholes, oriented perpendicular to the injection boreholes. Potential travel distances ranged from 20 cm to over 500 cm. Nonreactive tracer and weakly sorbing lithium breakthrough was observed at most of the collection points during the injection period. Following termination of injection, approximately 800 rock samples were collected using overcore and mineback techniques, and analyzed for tracer concentration. Rock analyses are discussed in a subsequent paper. To complement complex 3-dimensional finite-element modeling of the entire block, bromide, iodide, and lithium breakthrough onto the collection pads has been modeled with CXTFIT. This simple 1-dimensional analytical code uses a non-linear curve-fitting routine to estimate transport parameters including apparent velocity, dispersivity, and field retardation factors. Preliminary results show that: (1) Bromide and iodide behaved similarly, despite the fact that bromide was injected in a strongly transient flow field, while iodide injection began after flow had approached steady state conditions. (2) With the exception of the closest collection points, tracer velocities remained relatively constant, indicating that transport was effectively 1-dimensional. (3) Scale-dependent dispersion was observed, with dispersivities increasing from less than 1 cm for the shortest travel distances, to approximately 10 cm over longer distances. (4) Field lithium velocities were consistently faster than predicted using laboratory batch-sorption results.

The UZTT test facility is located approximately 8 km southeast of the potential Yucca Mountain repository area. The UZTT was designed in two phases, to address five specific objectives in the UZ: the effect of heterogeneities, flow and transport (F&T) behavior at permeability contrast boundaries, migration of colloids, transport models of sorbing tracers, and scaling issues in moving from laboratory scale to field scale. Phase 1A was designed to assess the influence of permeability contrast boundaries in the hydrologic Calico Hills. Visualization of fluorescein movement, mineback rock analyses, and comparison with numerical models demonstrated that F&T are capillary dominated with permeability contrast boundaries distorting the capillary flow. Phase 1B was designed to assess the influence of fractures on F&T and colloid movement. The injector in Phase 1B was located at a fracture, while the collector, 30 cm below, was placed at what was assumed to be the same fracture. Numerical simulations of nonreactive (Br) and reactive (Li) tracers show the experimental data are best explained by a combination of molecular diffusion and advective flux. For Phase 2, a numerical model with homogeneous unit descriptions was able to qualitatively capture the general characteristics of the system. Numerical simulations and field observations revealed a capillary dominated flow field. Although the tracers showed heterogeneity in the test block, simulation using heterogeneous fields did not significantly improve the data fit over homogeneous field simulations. In terms of scaling, simulations of field tracer data indicate a hydraulic conductivity two orders of magnitude higher than measured in the laboratory. Simulations of Li, a weakly sorbing tracer, indicate less retardation than predicted from laboratory batch measurements.

In the event of a failure of engineered barriers in the repository, the saturated alluvium down gradient of Yucca Mountain is expected to serve as a natural barrier to the migration of radionuclides to the accessible environment. Therefore, it is necessary to study radionuclide sorption characteristics of the saturated alluvium. In this study, batch sorption experiments were carried out to determine the apparent distribution coefficients, K (sub d) (ml/g) of (super 233) U(VI) (half-life = 1.592X10 (super 5) years) onto alluvium materials from three different wells located south of Yucca Mountain at varying depth intervals. We used three different particle-size fractions of the alluvium (500-2000, 75-500 and <75 micrometers) and tracer solutions that were prepared by dilution of (super 233) U(VI) hydrochloric acid stock solution with the corresponding well groundwater. The resulting solutions were analyzed for (super 233) U(VI) before and after contact with the alluvium by Liquid Scintillation Counting. Our results showed that (super 233) U(VI) K (sub d) values varied from 2 to 23 ml/g, with a tendency toward smaller K (sub d) values at greater depths below land surface and larger K (sub d) values for smaller alluvium particle size fractions (<75 micrometers). The latter result is not surprising given that the smallest particles have the largest surface area as well as the largest weight percentage of clays and zeolites, with their characteristically high adsorption capacities. The desorption behavior of (super 233) U(VI) from alluvium and the dependence of both (super 233) U(VI) sorption and desorption on alluvium mineralogy are currently being investigated.

The test was designed to address uncertainties associated with flow and transport models within the Topopah Springs and Calico Hills tuffs. The tracer mixture included nonreactive (Br, I, and FBAs) and reactive tracers (Li, Ce, Sm, Ni, Co, and Mn) and synthetic colloids. Once injection was completed, samples from the block were collected in two ways. Overcores were taken from around and below injection holes. Then, the entire block was excavated via mineback--during which progressive vertical planes of the block were exposed. Samples from the overcores and mineback were analyzed to determine the distribution of tracers on different spatial scales than available from collection borehole data. Rock analyses confirmed collection pad results that the nonreactive tracers, Br and FBAs, moved several meters. Furthermore, Br and FBAs are observed above and lateral to the injector planes suggesting that capillarity was an important process for tracer movement. Lithium, the most mobile of the metals, was transported on a scale of meters. This is consistent with laboratory sorption measurements and observed breakthrough on the collection pads. Co and Ni show transport distances of tens of cm, while Sm and Ce moved far less, possibly due to precipitation and sorption effects. Colloid transport was assessed using 1 ft3 blocks extracted from the BB Phase 2 block. In the Calico Hills material, after 15 L of water was injected over 3.5 months, less than 1% of the colloids injected were recovered. Flow patterns in the block indicate that water injected at the center imbibed outward from the injection point. In a block taken from a boundary of the Calico Hills ashfall layer, breakthrough was observed only due to fractures formed during drying of the block. The colloid transport module for FEHM was tested against colloid data from the 1 ft3 block scale laboratory experiments with excellent agreement.

Given the important implications of these data for evaluating unsaturated-zone transport rates, we conducted laboratory experiments to quantify effects of sample processing method on 36Cl and total Cl release from welded tuff from Yucca Mountain. Measured 36Cl/Cl ratios were larger for samples left undisturbed during the leach processes (passive leach) when compared to those from samples that were continuously shaken during the leach processes (active leach). Measured 36Cl/Cl for the active-leach sample are inversely correlated with Cl concentrations, suggesting mixing between meteoric and rock components. In several different samples, the active-leach method extracted on average 1.4 times (up to 2.75 times) more Cl than did the passive-leach method. These data indicate that the 36Cl/Cl ratios may be lowered by dilution with rock Cl sources as a result of active leach methods. 36Cl/Cl for 7 of 10 passive-leach samples change little over a 48 hour leach (individual leach samples taken at 0.5, 2, 7, and 48 hrs), with values between 500E-15 and 800E-15 that are consistent with the natural background 36Cl/Cl for meteoric water at Yucca Mountain. 36Cl/Cl for 3 of the passive-leach samples show a decrease in the 36Cl/Cl with time, consistent with early release of a minor bomb-pulse component. These data indicate that laboratory procedures used for earlier and current LANL research have effectively extracted Cl carried in by infiltrated water, with minimal dilution of the meteoric signal by volcanic Cl sources. The data also suggest that leach times <2 hr may be more effective than longer leaches in isolating bomb-pulse 36Cl signature from crystalline rocks.

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

Average annual rainfall in the area is approximately 200 mm, and there are no known drips or seeps into the cave. There are no active calcite speleothems in the cave; one area is spectacularly decorated with halite speleothems. The cave intercepts the water table at a number of pools, which are dominated by sodium chloride with an average TDS of 9500 mg/L. In-cave pool samples were complemented by regional borehole groundwater samples spanning a 45-km transect. The regional aquifer is similar in chemistry to the cave pools, ranging in TDS from 8500 to 13,400 mg/L. All cave pool and groundwater samples showed higher chloride/bromide ratios than seawater, suggesting a terrestrial halite source for at least some of the observed chloride. Stable isotope ratios for cave pool water and regional groundwater are tightly clustered to the right of the present-day meteoric water line, and are lighter overall than average modern precipitation. Together, these observations suggest that the samples reflect old water from a different climatic regime. Although Mullamullang Cave pools display a strong horizontal thermal gradient (increasing from 16.5 degrees C to 21.0 degrees C in 5 km), the uniform stable isotope ratios do not indicate strong evaporative convection cells. Tritium and chlorine-36 analyses are currently underway, and will be discussed in terms of salinity sources and groundwater ages.

Mineralogical and geochemical analyses can provide data on properties of a site that are either difficult to model accurately or are not embodied in models that are based on incomplete or faulty concepts. For example, determination of long-term or cumulative fluid flux can be constrained where cation-exchanging minerals such as zeolites have acted over geologic time scales as efficient accumulators of cations from solutions with approximately known cation concentration. Another important but often ignored property, mineral surface-mediated heavy-metal redox reactions, can be demonstrated where Pu analogs such as Ce have been shown to be removed from solution as Ce4+ by Mn-oxides. Sites where Ce has accumulated can be mapped to determine specific horizons or features where other heavy metals may accumulate. Such maps can be critical in evaluating remediation approaches or repository design. In some instances, the effective distance over which metals are removed from solution can be demonstrated where a "passive" accumulator such as calcite records diminishing concentrations of redox-sensitive metals in groundwater with distance from a dissolution source. Use of geochemical observations to establish a history of long-term site performance provides a level of understanding that can augment short-duration field tests and can be used to evaluate models of long-term performance. In addition, geochemical and mineralogical data can supplement the results of modeling, particularly emphasizing processes that have not been modeled (e.g., strong retention of heavy metals by trace fracture-lining minerals). Results from modeling can be tested when a predicted outcome is either supported or contradicted by geochemical evidence (e.g., predicted impermeability of zeolitized tuffs versus geochemical evidence for through-flow). Perhaps the greatest benefit of site-specific geochemical evaluation is the demonstration to analysts, regulators, and the public that a defensible data-based understanding of the long-term behavior of a site has been obtained using data obtained from the site.

In this study, conceptual models of vadose-zone flow and transport processes are developed through the interpretation of field data and synthesis with numerical models. The types of data incorporated into the development of the conceptual model include moisture content and pore-water chemical compositions in borehole samples, a fluid injection experiment with monitoring of moisture plume migration, contaminant concentration distributions, air permeability testing, and downhole air pressure responses to barometric signals. The observations include sites under natural conditions and sites experiencing periods of enhanced water application due to surface disturbances resulting from LANL facilities. The key conceptual model elements describe percolation of water through both fractured and relatively unfractured volcanic tuffs, buried sedimentary formations and basalts. The conceptual model differentiates the rate of these processes by their location and surface hydrologic setting, including wet and dry canyons, natural mesas and disturbed mesas. Infiltration beneath wet canyons is the highest with rates on the order of meters per year (100-1000 mm/yr). Transport to the regional aquifer beneath wet canyons is on the order of decades to hundreds of years, depending on the thicknesses of the various hydrostratigraphic layers. Perched water is typically found beneath wetter canyons, resulting from low-permeability units such as unfractured regions of the basalt flows and buried soils. Percolation through the volcanic tuffs is generally considered to be via matrix-dominated flow, whereas fracture flow may play a key role in contaminant transport through basalt units beneath wet canyons. Infiltration beneath dry canyons and dry mesas is much slower (ten mm/yr or less), yielding transport times to the aquifer of hundreds to several thousands of years. However, long-term surface disturbances at mesa-top locations may alter infiltration rates such that at a local scale, they approach those of wetter canyons.

There is intensifying competition over the limited resources and growing concern about the impact of pumping on aquifer recharge and discharge and the fate of contaminants. To address these concerns, we estimate capture zones for several municipal wellfields using a three-dimensional numerical inverse model of the Espanola Basin regional aquifer. The simulated capture zones have a complex three-dimensional structure, due to geologic heterogeneity, exchange with surface waters, complex spatial distribution of groundwater recharge, and interference between pumping wells. We present sensitivity of our results to model parameter uncertainty, departures from steady-state, and uncertainty in the geology model. Parameters controlling the spatial distribution of recharge are amongst the most critical.

Before May 2000, most of the sediment and runoff in these canyons were generated by summer thunderstorm rainfall on the sparsely vegetated Pajarito Plateau (which produces primarily medium sand and coarser sediment), as rainfall on the mountain front was generally intercepted by the dense forest canopy or infiltrated into deep soils. In May 2000, the Cerro Grande fire burned nearly 175 km2 of primarily ponderosa and mixed conifer forest in the Jemez Mountains and Pajarito Plateau, with the most severely burned areas in the steeper, montane portions of the watersheds. As a result of the loss of forest canopy and ground cover, and the formation of hydrophobic soils, the primary locus of runoff and sediment generation in the Pajarito Plateau watersheds shifted westward to the mountain front. In the canyons draining the Pajarito Plateau, large floods and fine-grained (fine sand, silt, and clay) sediment produced on the steep, soil-mantled slopes of the Jemez Mountains supplemented the moderate flash floods and coarser sediment normally derived on the Pajarito Plateau. Pueblo Canyon (drainage area 21.7 km2) was one of the most severely burned watersheds, with the upper 5 km2 affected by high severity burn and nearly 100% tree mortality. Pre- and post-fire field data from Pueblo Canyon and nearby Los Alamos Canyon, including runoff and sediment transport data from flash floods, repeated cross section surveys, reservoir sedimentation surveys, and floodplain stratigraphic information were used to quantify coarse and fine sediment input, export, and exchange in Pueblo Canyon after the Cerro Grande wildfire. Prior to the fire, the sediment budget of Pueblo Canyon was influenced by decadal fluctuations in sand supply and exchanges with the channel bed, resulting in downstream-propagating aggradation/degradation cycles. Since the fire, runoff and sediment production from the Jemez Mountains temporarily increased by over two orders of magnitude, supplying large quantities of sediment and ash in a series of flood events, resulting in widespread sediment exchange with the floodplain and local channel aggradation and degradation.

However, the distribution of hydraulic properties, such as hydraulic conductivity, may possess a multiplicity of modes; thus the first two moments may not be adequate to characterize properties of such porous media. In turn, the stochastic models developed for unimodal porous media may not be applicable to flow and transport in a multimodal heterogeneous porous medium. This study investigates under what circumstances the second-order moment-based stochastic models are applicable to multimodal heterogeneous porous media. We assume that a porous medium is composed of a number of materials (categories), each of which may have a different mean, variance, and correlation scale. The distribution of materials in the domain is characterized by indicator random variables. We first derive analytical expressions for the mean and covariance of the log saturated hydraulic conductivity (ln K sub(s)) of the multimodal porous medium in terms of categorical proportions, transition probability among categories, and covariances of indicator random variables. We express the covariance in terms of the statistics of materials in the porous medium, which allows us to accurately evaluate the variance and the correlation length of the composite ln K sub(s) field. We then solve the second-order moment equations for the "equivalent" unimodal field with an exponential covariance with a single correlation scale computed for the composite field. On the other hand, we conduct two sets of Monte Carlo simulations: one with multimodal random fields, and the other with "equivalent" unimodal random fields. Examples for porous media with two materials are given. Numerical experiments show that a bimodal ln K sub(s) field may be well approximated by an equivalent unimodal field when one of the two modes is dominant, under which condition the applicability of the second-order moment-based model is subject to the same limitation of relatively small variance as that for unimodal fields. When the bimodal distribution has two more or less equally important modes, although it cannot be adequately represented by an equivalent unimodal distribution, the second-order moment-based stochastic model seems to be applicable to systems with larger composite variances than it does for an one-mode-dominant distribution.

This study investigated the developmental cost of mounting a humoral immune response in growing mountain chickadees, Poecile gambeli. We immunologically challenged nestling chickadees using nonpathogenic antigens of either Newcastle disease virus vaccine or sheep red blood cells. Body mass, tarsal length, haematocrit, total plasma protein, and survival did not vary significantly between antigen treatment groups and control groups. Developmental stability was assessed using fluctuating asymmetry (FA) between the right and left ninth primary feather length. FA was increased significantly in the antigen-challenged birds. This result indicates that the up-regulation of the humoral immune response was developmentally costly to the nestlings by causing an increase in FA.

Although a large amount of biochemical data are available for the Escherichia coli ribosome, the structure has not been solved to atomic resolution. Using a new RNA homology procedure, we have modeled the all-atom structure of the E. coli 30S ribosomal subunit. We find that the tertiary structure of the ribosome core, including the A-, P- and E-sites, is highly conserved. The hypervariable regions in our structure, which differ from the structure of the 30S ribosomal subunit from Thermus thermophilus, are consistent with the cryo-EM map of the E. coli ribosome.

AN - 72050532; 12207247 AB - Supercritical fluid carbon dioxide (SC-CO(2)) has been used to dissolve derivatizing agents (e.g. heptafluorobutyric anhydride, HFBA, and pyridine), which also act as a modifier in the fluid phase, for simultaneous extraction and derivatization of carbamates from the sample matrix. The derivatized carbamate pesticides (carbaryl, 3-hydroxycarbofuran, carbofuran, aldicarb, methiocarb) were then analyzed by GC-ECD or GC-MS with excellent sensitivity. Extraction and conversion of the carbamates was complete, as indicated by HPLC with post-column hydrolysis and o-phthalaldehyde derivatization then fluorescence detection. GC-MS (ion trap) was also used to confirm the formation of the carbamate derivatives. Compared with the same HFBA reaction in an organic solvent the derivatization reaction time was considerably shorter in SC-CO(2.) The described approach, combining both extraction and derivatization, simplifies the analysis of carbamate pesticides and eliminates the use of organic solvents associated with the derivatization step.

Siderophores are Fe(III)-specific organic ligands produced by microorganisms under conditions of Fe stress. Siderophore production was compared with previous experiments wherein Fe was supplied as hematite [Geomicrobiol. J. 17 (2000) 1]. Microbial growth increased in the order: no-added-Fe controlkaolinite>hematite> or =Fe-EDTA. Thus, the bacterium was less Fe stressed in the presence of kaolinite than in the no-added-Fe control, confirming that kaolinite serves as a source of Fe to the bacterium. Although more siderophore per cell was produced in the most stressed system (no-Fe-added), more total siderophore was produced in the least stressed system (Fe-EDTA). This is due to the presence of a larger total population size in the least stressed system. Hence, the ability of a microbial population to produce siderophores as a means to access mineral-bound Fe is a complex function of both Fe stress and population size.

The clathrate cages are multiply occupied, with a cluster of two H (sub 2) molecules in the small cage and four in the large cage. Substantial softening and splitting of hydrogen vibrons indicate increased intermolecular interactions. The quenched clathrate is stable up to 145 kelvin at ambient pressure. Retention of hydrogen at such high temperatures could help its condensation in planetary nebulae and may play a key role in the evolution of icy bodies.

Yet only a small fraction of natural proteins are suitable for structure determination because of bottlenecks such as poor expression, aggregation, and misfolding of proteins, and difficulties in solubilization and crystallization. We propose to overcome these bottlenecks by producing soluble, highly expressed proteins that are derived from and closely related to their natural homologs. Here we demonstrate the utility of this approach by using a green fluorescent protein (GFP) folding reporter assay to evolve an enzymatically active, soluble variant of a hyperthermophilic protein that is normally insoluble when expressed in Escherichia coli, and determining its structure by X-ray crystallography. Analysis of the structure provides insight into the substrate specificity of the enzyme and the improved solubility of the variant.

The authors tested the suitability of a family-level biotic index for use in a river in west-central Mexico that receives organic point-source pollution from untreated municipal sewage and sugar-cane processing. The biotic index was highly correlated to dissolved oxygen, and could detect different levels of pollution. Information from rapid assessment biomonitoring was used successfully by local natural resource managers to help bring about improvements in water resource management.

AN - 71938453; 12137989 AB - The health consequences of beryllium (Be2+) exposure can be severe. Beryllium is responsible for a debilitating and potentially fatal lung disease, chronic beryllium disease (CBD) resulting from inhalation of beryllium particles. The US Code of Federal Register (CFR), 10 CFR 850, has established a limit of 0.2 microg beryllium/100 cm(2) as the maximum amount of beryllium allowable on surfaces to be released from beryllium work areas in Department of Energy (DOE) facilities. The analytical technique described herein reduces the time and cost of detecting beryllium on laboratory working surfaces substantially. The technique provides a positive colorimetric response to the presence of beryllium on a 30.5 cm x 30.5 cm (1 ft(2)) surface at a minimum detection of 0.2 microg/100 cm(2). The method has been validated to provide positive results for beryllium in the presence of excess iron, calcium, magnesium, copper, nickel, chromium and lead at concentrations 100 times that of beryllium and aluminum and uranium (UO2(2+)) at lesser concentrations. The colorimetric detection technique has also been validated to effectively detect solid forms of beryllium including Be(OH)2, BeCl2, BeSO4, beryllium metal and BeO.

AN - 85357591; pmid-12186031 AB - The acoustic power loss in the thermoacoustic mixture-separation process is derived, including the contributions due to a nonzero gradient in concentration. The significance of the gradient-dependent term is discussed. The limiting thermodynamic efficiency of the separation is calculated. Under reasonable circumstances, the efficiency approaches 10(-2) nHnL(delta m/m(avg))2, where nH and nL are the mole fractions of the two components of the mixture, and delta m/m(avg) is the fractional difference between the molar masses of the two components. This efficiency is of the same order of magnitude as that of some other, more conventional separation methods.

(super 3) He/ (super 4) He ratios indicate a deep magmatic source (R/R (sub a) up to 6) whereas delta (super 13) C-CO (sub 2) values (-3 to -5 per mil) do not discriminate between a mantle/magmatic source and a source from subjacent, hydrothermally altered Paleozoic carbonate rocks. Regional gases from sites within a 50-km radius beyond Valles caldera are relatively enriched in CO (sub 2) and He, but depleted in H (sub 2) S compared to Valles gases. Regional gases have R/R (sub a) values < or =1.2 due to more interaction with the crust and/or less contribution from the mantle. Carbon sources for regional CO (sub 2) are varied. During 1982-1998, repeat analyses of gases from intracaldera sites at Sulphur Springs showed relatively constant CH (sub 4) , H (sub 2) , and H (sub 2) S contents. The only exception was gas from Footbath Spring (1987-1993), which experienced increases in these three components during drilling and testing of scientific wells VC-2a and VC-2b. Present-day Valles gases contain substantially less N (sub 2) than fluid inclusion gases trapped in deep, early-stage, post-caldera vein minerals. This suggests that the long-lived Valles hydrothermal system (ca. 1 Myr) has depleted subsurface Paleozoic sedimentary rocks of nitrogen. When compared with gases from many other geothermal systems, Valles caldera gases are relatively enriched in He but depleted in CH (sub 4) , N (sub 2) and Ar. In this respect, Valles gases resemble end-member hydrothermal and magmatic gases discharged at hot spots (Galapagos, Kilauea, and Yellowstone).

There is a radial "sigmoidal" periodicity for both isotope ratios, but the two are out of phase, with high delta D values corresponding to low delta (super 18) O values. Periodicity for a 100- to 120-mm diameter nodule is approximately 16 mm, increasing slightly toward the rim, with amplitudes approaching 20 and 3.0 per mil for hydrogen and oxygen, respectively. The combined hydrogen-oxygen isotope data for one nodule fall on a published curve for chert forming in equilibrium with seawater ; the range of delta values corresponds to temperature variations of approximately 10 degrees C. Data for a second chert fall on a subparallel delta D-delta (super 18) O line with delta D values that are almost 50 per mil lower. The delta D-delta (super 18) O patterns for the nodules cannot be explained by periodic mixing of meteoric and ocean water because the hydrogen and oxygen isotope data are out of phase. Two possible explanations for the antiphase periodicity are (a) cyclical temperature variations, perhaps related to an unstable convection system (e.g., Bolton et al., 1999) and (b) self-organizing catalytic precipitation (e.g., Wang and Merino, 1990). The systematic isotopic variations are difficult to explain by diagenesis and strongly suggest that primary isotopic compositions are preserved. The isotopic data provide important information on the thermal history of the sedimentary basin, if temperature variations are the cause of the isotopic periodicity.

In soil solution, the speciation of Zn, and thus the free Zn activity, determines the plant availability of Zn as a micronutrient and its characteristics as a heavy metal contaminant. A better understanding of the mechanisms that control free Zn activity could improve soil treatments of Zn deficiency or toxicity. Possible controlling mechanisms for Zn activity include adsorption or precipitation. In our study, Zn (super 2+) activity was measured by chelation and was related to soil properties for 18 alkaline soils from three farms in eastern Colorado. Soil organic C (OC) and pH were statistically significant parameters in a multiple regression with log Zn (super 2+) activity. The significance of OC may suggest that adsorption onto organic matter controls Zn solubility in some of our soils. Log Zn (super 2+) activities plotted with pH fell near the soil-Zn solubility line. However, the slope of the regression line was -1 rather than an expected -2, which indicates that another mechanism besides precipitation and dissolution of soil Zn may occur. Another possibility is that there are two different regions of solubility, one below pH 8.4 and one above pH 8.4. It is suggested that free Zn ions may adsorb on organic matter in a region of low pH and may precipitate as franklinite or other minerals, such as a Zn-containing kerolite, at high pH.

The methods employ the ridge discrimination techniques first proposed by Smidt and McDonald (1976). Ridge discrimination was developed to address the problems associated with discrimination in high-dimension, colinear settings and is readily adaptable to linear, quadratic, and outlier identification rules. Ridge discrimination is a special case of regularized discrimination analysis (RDA) developed by Friedman (1989). RDA includes linear discrimination (LDA), quadratic discrimination (QDA), and Euclidean distance-based nearest mean discrimination in its parameterization. We propose a new approach to the optimal selection of RDA parameters. We show that the techniques presented in this article can be used to transition from an outlier analysis approach to seismic identification to classical discrimination, as quality explosion calibration data are collected. We demonstrate the importance of including the correlation structure between seismic measurements in event identification. Not including this correlation structure in any identification framework can aggravate identification errors and give an erroneous impression of capability. With the techniques presented, a large number of discriminants can be used and no a priori subselection of discriminants is necessary.

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

The general form of the dispersion tensor provides for distinct vertical and horizontal longitudinal dispersivity values. Transverse dispersion is isotropic for flow parallel to the symmetry axis and anisotropic for flow perpendicular to the symmetry axis with distinct horizontal and vertical transverse dispersivities. The new form of the dispersion tensor is applied to several examples involving axisymmetric media utilizing particle tracking techniques and compared to the tensor proposed by Burnett and Frind [1987]. It is demonstrated that for the case of spatially variable flow the drift term gradient times ( phi D)/ phi must generally be included in the particle tracking algorithm to obtain accurate results.

Composite porous media consist of disjoint blocks of permeable materials, each block comprising a single material type. Within a composite medium, hydraulic conductivity can be represented through a pair of random processes: (1) a boundary process that determines block arrangement and extent and (2) a stationary process that defines conductivity within a given block. We obtain second-order statistics for hydraulic conductivity in the composite model and then contrast them with statistics obtained from a standard univariate model that ignores the boundary process and treats a composite medium as if it were statistically homogeneous. Next, we develop perturbation expansions for the first two moments of head and contrast them with expansions based on the homogeneous approximation. In most cases the bivariate model leads to much sharper perturbation approximations than does the usual model of flow through an undifferentiated material when both are applied to highly heterogeneous media. We make this statement precise. We illustrate the composite model with examples of one-dimensional flows which are interesting in their own right and which allow us to compare the accuracy of perturbation approximations of head statistics to exact analytical solutions. We also show the boundary process of our bivariate model is equivalent to the indicator functions often used to represent composite media in Monte Carlo simulations.

The data indicate the presence of a subsurface layer enriched in hydrogen overlain by a hydrogen-poor layer. The thickness of the upper layer decreases with decreasing distance to the pole, ranging from a column density of about 150 grams per square centimeter at -42 degrees latitude to about 40 grams per square centimeter at -77 degrees . The hydrogen-rich regions correlate with regions of predicted ice stability. We suggest that the host of the hydrogen in the subsurface layer is ice, which constitutes 35 + or - 15% of the layer by weight.

The experiments are designed to mimic low degrees of anhydrous melting beneath mid-ocean ridges. The available data indicate that the partition coefficients are pressure, temperature, and composition dependent. Therefore partitioning behavior over the appropriate range of pressure, temperature, and composition must be quantified, in order to model continuous extraction of melt during the adiabatic rise of mantle material. For this purpose, we have parameterized the partitioning behavior of the REE, Hf, Zr, U, and Th based on a simple thermodynamic model. Although these parameterizations cannot be used for retrieving thermodynamic constants yet, they do yield accurate descriptions of the partitioning behavior that are useful for modeling decompression melting. Our parameterizations show that the partitioning of trace elements is strongly dependent on the Ca and Al-content of the clinopyroxene (cpx) and REE are always incompatible in cpx on the peridotite solidus at pressures up to 3.4 GPa. For garnet the data indicate that the heavy REE partition coefficients decrease with increasing pressure. Our data also indicates that Pb is more incompatible than Ce in clinopyroxene; Ce and Pb have similar partition coefficients in garnet. Therefore the presence of a residual phase with high Pb partition coefficients is required to produce the near-constant Ce/Pb ratios in MORB and OIB. Sulfides are the most likely phase to buffer the Pb content in the melt. Except at small porosities (<0.3%), clinopyroxene on the peridotite solidus is unable to fractionate U from Th significantly (15% 230Th-excess), whereas garnet can fractionate U from Th effectively at porosities up to 1%. Therefore if the 230Th-excesses in mid-ocean ridge basalts are melting phenomena, then melting with garnet residual is required in order to be compatible with physical observations on porosities and upwelling rate at mid-ocean ridges. New model calculations that include the compositional dependent partitioning of the trace elements show that the predicted physical characteristics (depth and extent of melting, upwelling rate, porosity) of the MORB melting regime are similar for the Lu/Hf, Sm/Nd, and U-Th systems.

These large bolides produced infrasonic signals at numerous stations in the Americas and Europe as well as being observed by US Department of Defence satellite sensors. The energy, location and physical characteristics of these bolides is inferred from available infrasound records and compared to satellite data. The infrasonic energy of the events from the observed signal frequencies is estimated to be 3 kT and 1 kT respectively, while the satellite energies are approximately 3 kT and 11 kT. The disagreement in energies for the April 23, 2001 (the third largest satellite observed bolide on record) event is significant and indicates acoustic/optical processes not typical of most bolides. The integrated infrasonic acoustic energy of the signals indicates that the percentage of acoustic energy deposited into the atmosphere is a minimum of 0.1-1% of the total source energy for each event.

The stratigraphy of trace metals, Pb-isotope ratios and mineralogy indicate extreme heavy metal pollution in recent sediments. In the pollutant trend, extremes coincide with maxima in 20th century metal production, minima during major war conflicts and the final shutdown of the smelter. Peak pollution concentrations measure up to 4.7 wt.% Zn, 1.1 wt.% Pb and 0.1 wt.% Cd, which correspond to calculated atmospheric deposition rates of 9.0, 1.6 and 0.16 g m super(-2) yr super(-1), respectively. super(206)Pb/ super(207)Pb isotope ratios show higher values in the polluted interval (1.135-1.162) relative to local geogenic values deeper down-core (1.194-1.215). Within the polluted interval, three significantly different super(208)Pb/ super(206)Pb plateaus are recognized and suggested to indicate changes in the origins of processed ores. Microprobe analyses on sediment thin sections show extensive in situ FeS sub(2) and ZnS precipitation, which suggests that anoxic processes are responsible for the immobilization of the atmospheric metal inputs. The occurrence of oxidized smelter dusts in an independent surface soil sample indicates a rapid diagenetic transformation of metal oxides into sulfides. Morphology and chemical characteristics allow the distinction between smelter related and diagenetic mineral deposits, and give evidence for dust from open-air ore repositories, as well as smelter operation without dust filters.

AN - 71862963; 12092753 AB - We investigated the interacting effects of a nonpathogenic immunological challenge and exposure to lead shot early in the development of nestling western bluebirds (Sialia mexicana). Nestlings were randomly assigned to each of six treatments of an incomplete block design with two antigen treatments, Newcastle disease virus (NDV) or sheep red blood cells (SRBC), and four lead shot treatments (no shot, one shot--0.05 g, 2 shots--0.1 g, or three shots--0.15 g). Survival functions did not differ between the lead treatment groups, and there were no effects of lead treatments on weight, growth rates, fluctuating asymmetry (FA), or antibody response. NDV- and SRBC-treated birds survived better than control birds which may be due to an adjuvant-activation of the entire immune system. However, FA was greater in individuals in the NDV and SRBC treatment groups, suggesting a tradeoff between growth and immunocompetence. Cell-mediated response to phytohemagglutinin of the high-lead treatment groups was significantly less than other groups. Hematocrit increased with age and weight, and was not affected by lead or antigen. While in this study the shape of the growth curve, FA, cell-mediated immunity, and behavior were affected by the higher dose of lead shot, actual lead concentrations in blood are needed to verify this process. Antigenic stress was documented in nestling developmental stability and there were no measured effect of both the lead shot and immunological challenge in combination.

This quantity represents cosmogenic (super 21) Ne produced on the Fish Canyon Tuff surface prior to the deposition of the overlying Carpenter Ridge Tuff. Ancient (super 21) Ne was isolated through the analysis and identification of (1) background (super 21) Ne produced from alpha -particle interactions or inherited; and (2) cosmogenic (super 21) Ne produced from modern radiation. Multiple samples of Fish Canyon Tuff shielded during both exposure periods, 28 Ma ago and in modern time, yielded the background that was then subtracted from all samples. Likewise, samples of Fish Canyon exposed today, but well below the Fish Canyon-Carpenter Ridge contact and therefore shielded 28 Ma ago, yielded a modern component that was also removed from all sample concentrations. The presence of an ancient cosmogenic isotope in a buried surface has several potential applications, including the quantification of paleoelevation, paleolatitude, and pre-Quaternary erosion rates.

Plutonium solubilities determined experimentally at pH values of 6, 7, and 8.5 are about two orders of magnitude higher than those calculated using the existing thermodynamic database indicating the influence of colloidal Pu(IV) species. Solid phase characterization using X-ray diffraction revealed primarily Pu(IV) in all precipitates formed at pH 6, 7, and 8.5. The solubility controlling Pu-bearing solids precipitated at ambient temperature consisted of amorphous Pu(OH) (sub 4) (s) with several Pu-O distances between 2.3 and 2.7 Aa that are characteristic for Pu(IV) colloids. High temperature (90 degrees C) increased solid phase crystallinity and produced Pu(IV) solids that contained Pu oxidation state impurities. X-ray absorption spectroscopic studies revealed diminished Pu-O and Pu-Pu distances that were slightly different from those in crystalline PuO (sub 2) (s). A Pu-O bond of 1.86 Aa was identified that is consistent with the plutonyl(V) distance of 1.81 Aa in PuO (sub 2) (super +) (aq). Hematite, montmorillonite, and silica colloids were used for uptake experiments with (super 239) Pu(V) and (super 237) Np(V). The capacity of hematite to sorb Pu significantly exceeded that of montmorillonite and silica. A low desorption rate was indicative of highly stable Pu-hematite colloids, which may facilitate Pu transport to the accessible environment. Neptunium uptake on all mineral phases was far less than Pu(V) uptake suggesting that a potential Pu(V)-Pu(IV) reductive sorption process was involved. The temperature effect on Pu solubility and pseudocolloid formation is also discussed.

Laboratory experiments have documented toxic effects to herbivores consuming high-Ni plant tissues, but this paper reports the first experiment to examine the defensive effectiveness of Ni hyperaccumulation under field conditions. The experiment was conducted at an ultramafic soil site naturally inhabited by the Ni hyperaccumulator Streptanthus polygaloides (Brassicaceae). Experimental treatments examined the response of herbivores to hyperaccumulated Ni, using exclosure and insecticide treatments to divide herbivores into groups based primarily upon herbivore size. Three soils (Ni-amended greenhouse soil, unamended greenhouse soil, ultramafic soil), three exclosure treatments (exclosure, control exclosure, no exclosure), and a systemic insecticide treatment were combined in a fractional factorial experimental design. Streptanthus polygaloides plants were grown in a greenhouse for 2 mo, transplanted into the field by inserting potted plants into holes dug on the experimental site, and periodically examined for herbivore damage during a 41-d period. Initial surveys showed greater amounts of insect damage to plants with low tissue Ni levels, confirming the defensive effect of Ni against some insect herbivores, but large herbivores (probably vertebrates) later consumed entire plants regardless of plant Ni status. We concluded that Ni was not an effective defense against these large herbivores, probably because their diets mix high-Ni S. polygaloides foliage with that of associated non-hyperaccumulating species. We suggest that such dietary dilution is one mechanism whereby some herbivores can circumvent elemental plant defenses.

Lithium sorbs weakly by cation exchange and permits field-scale testing of laboratory-based predictions of reactive-solute transport. A series of laboratory studies show that Li sorption is nonlinear and varies with lithology in the different horizons of the tuff. In particular, both Li sorption and Li-specific cation-exchange capacity vary as functions of tuff mineralogy, and can be predicted given quantitative X-ray diffraction data. These results indicate that Li sorption is dominated by clay and zeolite minerals, and that sorption coefficients can be predicted given mineralogic analysis results.

These tests are intended to improve our understanding of unsaturated-zone transport processes, and to test our ability to predict field-scale behavior using laboratory-scale measurements. The field tests use a mixture of nonreactive and reactive tracers. Nonreactive tracers include Br super(-), I super(-), 5 different fluorobenzoic acids, Na fluorescein, and a pyridone derivative. Reactive tracers include the metals Li, Mn, Co, and Ni, and the organic dye rhodamine WT. Rock samples from 3 different stratigraphic units at the Busted Butte test facility have been extensively characterized lithologically and mineralogically, and analyzed for Fe and Mn oxide content. Sorption of Np, Pu, Am and the field tracers onto these 3 rocks has been measured using batch techniques. Results confirm that the nonreactive tracers are indeed nonreactive, and show that sorption of radionuclides and sorbing tracers increases with increasing degree of rock alteration, as evidenced by increasing levels of smectite and Fe and Mn oxides. Among the radionuclides, Am and Pu sorb much more strongly than Np; the tracers' degree of sorption is rhodamine WT=Li << Mn < Ni < Co. Pu, Co, Mn, Ni and rhodamine WT exhibits strongly nonlinear sorption; Mn and Ni behavior may reflect competition with Co for sorption sites.

We illustrate the problem with empirical data from small surveys (200-member 16S rRNA gene clone libraries) of four bacterial soil communities from two locations in Arizona. Among the four surveys, nearly 500 species-level groups (Dunbar et al., Appl. Environ. Microbiol. 65:662-1669, 1999) and 21 bacterial divisions were documented, including four new candidate divisions provisionally designated SC1, SC2, SC3, and SC4. We devised a simple approach to constructing theoretical null models of bacterial species abundance. These null models provide, for the first time, detailed descriptions of soil bacterial community structure that can be used to guide experimental design. Models based on a lognormal distribution were consistent with the observed sizes of the four communities and the richness of the clone surveys. Predictions from the models showed that the species richness of small surveys from complex communities is reproducible, whereas the species composition is not. By using the models, we can now estimate the required survey scale to document specified fractions of community diversity. For example, documentation of half the species in each model community would require surveys of 16,284 to 44,000 individuals. However, quantitative comparisons of half the species in two communities would require surveys at least 10-fold larger for each community.

Studies to date have largely focused on silica-induced production of ROS by lung phagocytes. In this study, we investigated the hypothesis that particulate silica (DQ12) can also induce elevations in intracellular ROS in a cancer-target cell type, i.e., human bronchial epithelial cells (BECs), via an indirect mechanism that involves ROS-inducing extracellular factor(s) that occur upon the interaction of silica with culture medium. The intracellular production of hydrogen peroxide (H sub(2)O sub(2)) in BECs was assessed by flow cytometry via monitoring dichlorofluorescein (DCF) fluorescence. Culture medium containing 10% human serum was incubated with silica particles in concentrations ranging from 10 to 50 mu g/ml, and following incubation for 1 h and removal of the particles, the resulting supernatants were added to BECs. Silica-treated medium induced significant increases in intracellular H sub(2)O sub(2) after the medium had been treated with as little as 10 mu g/ml of the particles. Further, the level of ROS increases in BECs in response to silica-treated medium was found to be virtually identical to that induced in cells that were directly treated with silica in suspension. Based on enzyme inhibitory studies, the mechanism for this increased generation of intracellular ROS appears to involve both mitochondrial respiration and a NAD(P)H oxidase-like system. Spectrofluorimetric experiments with the antioxidant enzymes superoxide dismutase and catalase showed that superoxide anions (O2 times -) and H sub(2)O sub(2) are generated in silica-treated medium, but these ROS do not fully account for the induction of the intracellular ROS response. Iron, on the other hand, was found to be crucial to the process. Our collective results suggest silica-aqueous medium interactions can lead to the generation of factor(s) that induce the intracellular production of potentially DNA-damaging ROS in BECs in a manner that does not require direct particle-cell interactions.

If air samplers are shut off during a class or tour, it may not be restarted at the end of the class or tour, preventing detection of low level airborne contamination or the measurement of a more significant release during a later operation. To enable clear communication during tours and classes a timer was designed and constructed that allows an air sampler to be shut of for a short, fixed duration and automatically restarted.

Simulations of heat and fluid flow in variably saturated host rock near a magmatic intrusion provide insight into contact metamorphic processes, including dryout, condensation, and resaturation effects and implications for host-rock alteration. The numerical code, an enhanced version of FEHM, uses a finite-element/finite-volume technique incorporating implicit Newton-Raphson iteration to solve non-linear conservation equations for mass and energy, using thermodynamic properties of water and air in the ranges 10 degrees C< or =T< or =1500 degrees C, 0.00123< or =P< or =1000 MPa and 10 degrees C< or =T< or =1500 degrees C, 0.00123< or =P< or =22 MPa, respectively. The study area is located at Paiute Ridge, eastern Nevada Test Site, Nevada, USA, where hypabyssal mafic intrusions were emplaced at about 8.5-8.6 Ma (Ar/Ar age estimate) and cooled contemporaneously with part of a geomagnetic field reversal, inferred from paleomagnetic data from over 100 sites in intrusions and remagnetized host ash-flow tuffs. We used a radial model of heat flow and multiphase pore fluid flow adjacent to a 1200 degrees C intrusion to characterize the thermal evolution of the contact metamorphic system. For likely initial pore saturations of 0.4-0.6, an expanding dryout zone near the intrusion and a condensation zone of enhanced saturation (S< or =0.8) extends 150-400 m from the intrusion. Host-rock temperatures reach 800 degrees C near the contact and cool below 100 degrees C within 2000 yr after emplacement, two to four times faster than predicted by a simple conduction model. The thermal history of the system is very sensitive to initial saturation. The multiphase thermal model allows bounds to be placed on the rate of change of the transitional part of the geomagnetic field during the field reversal recorded at Paiute Ridge. We assume that magnetization acquisition took place during the life of the thermal system that developed in the intrusions and contact rocks and that the paleomagnetic data provide a quasi-continuous record of the transitional part of the reversal. Sites in intrusions and thermally annealed ash-flow tuffs reveal subtle yet systematic variations in paleomagnetic directions. We combine the directional data with robust thermal (temperature/time) models to estimate the rate of change of the geomagnetic field. Modeled times of 140-290 yr and 215-440 yr for the duration of magnetization acquisition at two different sites correspond to estimated rates of change of 0.06-0.13 degrees /yr for the field during the transitional part of the reversal.

Above a critical shock strength, many small close-packed grains nucleate in the shock-compressed body-centered cubic crystal growing on a picosecond time scale to form larger, energetically favored grains. A split two-wave shock structure is observed immediately above this threshold, with an elastic precursor ahead of the lagging transformation wave. For even higher shock strengths, a single, overdriven wave is obtained. The dynamics and orientation of the developing close-packed grains depend on the shock strength and especially on the crystallographic shock direction. Orientational relations between the unshocked and shocked regions are similar to those found for the temperature-driven martensitic transformation in iron and its alloys.

From these models we estimate the pre-atmospheric mass of the Tagish Lake meteoroid to be approximately 56 tonnes and its porosity to be between 37 and 58%, with the lowest part of this range most probable. These models further suggest that some 1300 kg of gram-sized or larger Tagish Lake material survived ablation to reach the Earth's surface, representing an ablation loss of 97% for the fireball. Satellite recordings of the Tagish Lake fireball indicate that 1.1X10 (super 12) J of optical energy were emitted by the fireball during the last 4s of its flight. The fraction of the total kinetic energy converted to light in the satellite pass band is found to be 16%. Infrasonic observations of the airwave associated with the fireball establish a total energy for the event of 1.66+ or -0.70 kT TNT equivalent energy. The fraction of this total energy converted to acoustic signal energy is found to be between 0.10 and 0.23%. Examination of the seismic recordings of the airwave from Tagish Lake have established that the acoustic energy near the sub-terminal point is converted to seismic body waves in the upper-most portion of the Earth's crust. The acoustic energy to seismic energy coupling efficiency is found to be near 10 (super -6) for the Tagish Lake fireball. The resulting energy estimate is near 1.7 kT, corresponding to a meteoroid 4 m in diameter. The seismic record indicates extensive, nearly continuous fragmentation of the body over the height intervals from 50 to 32 km. Seismic and infrasound energy estimates are in close agreement with the preatmospheric mass of 56 tonnes established from the modeling. The observed flight characteristics of the Tagish Lake fireball indicate that the bulk compressive strength of the pre-atmospheric Tagish Lake meteoroid was near 0.25 MPa, while the material compressive strength (most appropriate to the recovered meteorites) was closer to 0.7 MPa. These are much lower than values found for fireballs of ordinary chondritic composition. The behavior of the Tagish Lake fireball suggests that it represents the lowest end of the strength spectrum of carbonaceous chondrites or the high end of cometary meteoroids. The bulk density and porosity results for the Tagish Lake meteoroid suggest that the low bulk densities measured for some small primitive bodies in the solar system may reflect physical structure dominated by microporosity rather than macroporosity and rubble-pile assemblages.

A spectrum of features, including elongated, streamlined, flute-shaped lobes, and irregular corrugations, are exposed on the base of the lava lake. Flute-shaped lobes range in amplitude from several centimeters to 0.5 m, plunge downdip with respect to the subjacent layered tuff toward the center of the crater, and are better defined at depths more than 3 m below the lava lake surface. These may have been formed by growth of Rayleigh-Taylor instability waves caused by the density contrast between the wet tuff and basalt, combined with directed stress from flow of the lava lake radially outward from the crater. Formation of an insulating vapor film at the wet tuff-basalt interface and downward pressure exerted by the lava lake allowed the edge of the lava lake to quench gradually, and prevented formation of peperite at greater depths in the lake. Corrugations exposed on the upper 1.5 m of the lava lake margin increase in size from several millimeters to 10 cm in amplitude toward the top of the lava lake and approximately parallel the surface. Corrugations may be the remnant of fluidal peperite preserved on the edge of the lava lake, where the peperite was eroded, or may be deformation features formed within an insulating vapor film due to oscillation of the vapor film. These were formed higher in the lava lake, where the lava lake basalt was thinner, wet tuff deposits confining the lava lake were thinner, and temperature differences between the wet tuff and lava were greater. If corrugations represent deformation of the lava edge within the vapor film, rather than peperite formation, they preserve an intermediate process that is involved in the formation of peperite. This study offers a unique opportunity to evaluate some of the initial mechanisms involved in the formation of peperite based on features preserved in the lava where the host rock, in this case hydrovolcanic tuff, has been eroded but the properties of the host rock are known from adjacent exposures.

These experiments also show explosive behavior, developing Strombolian- and Surtseyan-like bursts. The results demonstrate that the application of fuel-coolant interaction (FCI) theory is appropriate for interpretation of peperites. The theory described includes discussion of the importance of mass interaction ratios of wet sediment and magma (R (sub s) ), which determine thermal equilibrium temperature limits and contact interface dynamics. The dynamics of the interface between magma and wet sediments involves heat transfer over a wide range of rates from passive quenching to explosive fragmentation. A vapor film layer develops at the interface and acts both as an insulating barrier, promoting passive quenching, as well as a potential energy reservoir that can cause magma fragmentation, mingling of the magma with wet sediments, and explosive quenching when the vapor film becomes unstable. An important parameter in determining the behavior of the vapor film is the value of R (sub s) , which controls whether heat can be convectively removed from the layer as more is being added from its contact with magma. If R (sub s) >1 for fully saturated sediments, there is enough water in the sediments to make convective heat flow effective in quenching the magma, but below that value, there is the potential that the vapor film will be unstable, producing highly dynamic phenomena, including explosive fragmentation. At values of R (sub s) <0.1 there is insufficient water to allow the escalation of explosive fragmentation.

AN - 71559912; 11799117 AB - Previous neutron scattering studies elaborated the topographical relationship of the regulatory (R(IIalpha)) and catalytic (C(alpha)) subunits of the cAMP-dependent protein kinase. We present here the results of a set of computations that lead to an atomic model of the cAMP-dependent protein kinase heterodimer, Delta(1-91)R(IIalpha)-C(alpha). The first step in the modeling utilized the crystal structures for the porcine C(alpha) and bovine Delta(1-90)R(Ialpha) or rat Delta(1-111)R(IIbeta), to homology-model structures of the species and isoforms that had been used in the neutron scattering experiments (bovine C(alpha) subunit and murine Delta(1-91)R(IIalpha) subunit, respectively). A docking procedure, constrained by the dimensions and positions of the ellipsoids in the neutron-derived R-C model as well as mutagenesis data, was used to develop "best fit" models for the heterodimer. Simulated annealing, molecular dynamics, and energy minimization were then used to refine the side chain packing at the heterodimer interface. For comparison, the calculations were done using the homology models derived from both the R(Ialpha) and R(IIbeta) crystal structures. Both resultant models had many similarities. Each predicted similar interfaces. The R(Ialpha)-based model has 25% more hydrogen bonds than that based on R(IIbeta), with seven of these potential bonds in common. The distribution of hydrophobic, polar, and charged residues at the interface was similar for both models, with a distribution more characteristic of the exposed surface residues than those in the protein interior. The calculated interface area in each is relatively small (<2000 A(2)). The R(Ialpha)-based model, however, has a significantly better fit with the scattering data and is therefore the one of distinctly higher probability. With its small interface area that has a high proportion of charged and polar residues, the complex appears poised for dissociation, and each subunit existing as a stable entity. This result is consistent with the known physiological events required for cAMP-dependent activation of the kinase.

AN - 85370115; pmid-12002850 AB - The theory for thermoacoustic mixture separation is extended to include the effects of a nonzero concentration gradient. New data are presented, which are in excellent agreement with this theory. The maximum concentration gradient which may be achieved in a binary mixture of gases through this separation process is intrinsically limited by the fractional pressure amplitude, by the tidal displacement, and by the size of the thermal diffusion ratio. Ordinary diffusion further detracts from the attainable final concentration gradient and can become the dominant remixing process as the cross section of the duct is increased. Rayleigh streaming also works against thermoacoustic separation, and an estimate of the molar flux from streaming is given.

The principal pathways within this system are fractures that penetrate the tuff. Large fractures that host deep root penetration provide a setting in which clay deposits accumulate through particulate or colloidal migration from the soil zone. Clays throughout the system are predominantly expandable interstratified illite/smectites (I/S), but clays of the tuff matrix at depth are distinctly Fe-rich and are not mixed with clays transported from the surface into fractures. Chemical alteration superimposed on clay particles transported into fractures results in clays with lower Al : Si ratios, higher Na, and higher lanthanide content with increasingly negative Eu anomalies with depth. These changes are accompanied by invasion and precipitation of Mn oxides, principally birnessite, within clay bodies. Investigation of the Mn oxides by synchrotron X-ray fluorescence (SXRF) shows that Mn is associated with Ba, Ce, Ni, and Pb. In addition, synchrotron X-ray absorption near-edge structure (XANES) spectra show that Ce in Mn oxides occurs as Ce (super 3+) and Ce (super 4+) , with average Ce oxidation state of approximately 3.75. The Mn oxides intergrown with clays actively participate in removal of Ce from solution, accompanied by oxidation of Ce (super 3+) to Ce (super 4+) . Other lanthanides are accumulated by the clays but are not concentrated along with Ce in the Mn oxides. Extraction of Ce from solution by Mn oxides is more effective than lanthanide accumulation in clay, a process that is variable and likely influenced by defects, extent of recrystallization, and particle sizes. This dichotomy in lanthanide interaction results in locally constant Ce content but either negative or positive Ce anomalies in the clay-Mn oxide system as a consequence of variability in the abundance of the other lanthanides. Nevertheless, the net lanthanide pattern for the sum of all clay-Mn oxide samples in either shallow or deep fractures has no Ce anomaly, indicating that other lanthanides segregated from Ce are not transported beyond the range of either the shallow or deep fracture systems. Evidence from Eu anomalies indicates that lanthanides accumulated in the fracture clays are acquired from the local tuff. The clay-Mn oxide assemblage is more effective than clay alone in accumulating of a wide variety of heavy metals.

Beneath stream channels, vertical temperature profiles vary over time in response to the rate of downward heat transport, which is dominated by conductive heat transport during dry periods, and by advective transport during channel infiltration. A relatively simple heat and liquid-water transport simulation code is coupled with an optimization code to inversely fit simulated sediment temperatures to observed temperatures during periods of streamflow. Percolation rates focused beneath stream channels were examined for a perennial, seasonal, and ephemeral channel in central New Mexico. At greater depth, water percolating through the vadose zone perturbs the local geothermal gradient to create a steady concave upward temperature profile, while upward fluxes of water perturb the gradient to create a concave downward profile. An analytical solution to the heat transport problem was developed for generating a family of temperature profiles, based on a series of recharge rates. Temperature profiles were matched to observed borehole temperatures to determine a net recharge rate in basin fill material beneath Frenchman Flat, NV. The complexities of stratigraphy and vapor movement were incorporated into a heat and water transport model for matching simulated temperature profiles to observed profiles for estimating deep percolation rates. Deeper percolation beneath expansive inter-channel basin fill sediments was examined below Frenchman Flat, NV. Deep percolation was examined in the complex bedrock beneath Yucca Mountain, NV. Temperature-derived results suggest that deep potential recharge represents a fraction of 1% of percolation rates beneath stream channels, however, more conclusive results are limited by the lack of shallow vs. deeper temperature data at the same site.

Detailed field mapping of the Santaquin and Payson lakes quadrangles provides evidence for a large wavelength fold containing at least 18 km of measured Proterozoic to Mesozoic rock within the thrust fault's allochthon. This feature is most likely linked to the asymmetry of the Oquirrh Basin wherein the thickness of the Oquirrh Group and time-correlated sediments abruptly changes westward from 1400 m to 9300 m near Orem. The geometry of the basin indicates it was most likely bounded to the east by a large listric normal fault with associated growth strata. The geometry of contractional structures indicates that the hanging wall of the Oquirrh Basin was most likely inverted along reactivated faults to form the Charleston-Nebo thrust sheet. Tmax and TOC (total organic carbon) analysis of the Manning Canyon Shale, Oquirrh Group, and Deseret Limestone within the Santaquin and Payson lakes quadrangles indicates that all of the samples reached temperatures in excess of the oil window (higher than 120 degrees C), but less than 225 degrees C (where carbon alters to graphite). These data, along with thermochonology data from the Santaquin metamorphic complex yield paleotemperatures for hanging wall units that indicate a burial than could only be reconciled with deposition as growth strata against a listric fault.

Total DNA was extracted from cyanobacteria-, lichen-, or moss-dominated crusts that represent different successional stages in crust development, and which contribute different amounts of carbon and nitrogen into the ecosystem. Cyanobacterial 16S rRNA genes were amplified by PCR using cyanobacteria-specific 16S rDNA primers. Both TRF and clone sequence analyses indicated that the cyanobacterial crust type is dominated by strains of Microcoleus vaginatus, but also contains other cyanobacterial genera. In the moss crust, M. vaginatus-related sequences were also the most abundant types, together with sequences from moss chloroplasts. In contrast, sequences obtained from the lichen crust were surprisingly diverse, representing numerous genera, but including only two from M. vaginatus relatives. By obtaining clone sequence information, we were able to infer the composition of many peaks observed in TRF profiles, and all peaks predicted for clone sequences were observed in TRF analysis. This study provides the first TRF analysis of biological soil crusts and the first DNA-based comparison of cyanobacterial diversity between lichen-, cyano- and moss-dominated crusts. Results indicate that for this phylogenetic group, TRF analysis, in conjunction with limited sequence analysis, can provide accurate information about the composition and relative abundance of cyanobacterial types in soil crust communities.

In parallel studies, the composition of the total bacterial community and of members of the Acidobacterium division were assessed in arid grassland soils using terminal restriction fragment length polymorphism (TRF, also known as T-RFLP) analysis of 16S rRNA genes amplified from soil DNA. Bacterial communities associated with the rhizospheres of the native bunchgrasses Stipa hymenoides and Hilaria jamesii, the invading annual grass Bromus tectorum, and the interspaces colonized by cyanobacterial soil crusts were compared at three depths. When used in a replicated field-scale study, TRF analysis was useful for identifying broad-scale, consistent differences in the bacterial communities in different soil locations, over the natural microscale heterogeneity of the soil. The compositions of the total bacterial community and Acidobacterium division in the soil crust interspaces were significantly different from those of the plant rhizospheres. Major differences were also observed in the rhizospheres of the three plant species and were most apparent with analysis of the Acidobacterium division. The total bacterial community and the Acidobacterium division bacteria were affected by soil depth in both the interspaces and plant rhizospheres. This study provides a baseline for monitoring bacterial community structure and dynamics with changes in plant cover and environmental conditions in the arid grasslands.

AN - 71632701; 11944797 AB - Material Disposal Area G is the primary low-level radioactive waste disposal site at Los Alamos National Laboratory, New Mexico, and is adjacent to Pueblo of San Ildefonso lands. Pueblo residents and Los Alamos scientists are concerned about radiological doses resulting from uptake of Area G radionuclides by mule deer (Odocoileus hemionus) and Rocky Mountain elk (Cervus elaphus), then consumption of deer and elk meat by humans. Tissue samples were collected from deer and elk accidentally killed near Area G and were analyzed for 3H, 90Sr, total U, 238Pu, 239,240Pu, 241Am, and 137Cs. These data were used to estimate human doses based on meat consumption of 23 kg y(-1). Human doses were also modeled using RESRAD, and dose rates to deer and elk were estimated with a screening model. Dose estimates to humans from tissue consumption were 2.9 x 10(-3) mSv y(-1) and 1.6 x 10(-3) mSv y(-1) from deer and elk, respectively, and RESRAD dose estimates were of the same order of magnitude. Estimated dose rates to deer and elk were 2.1 x 10(-4) mGy d(-1) and 4.7 x 10(-4) mGy d(-1), respectively. All estimated doses were significantly less than established exposure limits or guidelines.

AN - 71570937; 11931452 AB - Redistribution of soil, nutrients, and contaminants is often driven by wind erosion in semiarid shrublands. Wind erosion depends on wind velocity (particularly during episodic, high-velocity winds) and on vegetation, which is generally sparse and spatially heterogeneous in semiarid ecosystems. Further, the vegetation cover can be rapidly and greatly altered due to disturbances, particularly fire. Few studies, however, have evaluated key temporal and spatial components of wind erosion with respect to (i) erosion rates on the scale of weeks as a function of episodic high-velocity winds, (ii) rates at unburned and burned sites, and (iii) within-site spatial heterogeneity in erosion. Measuring wind erosion in unburned and recently burned Chihuahuan desert shrubland, we found (i) weekly wind erosion was related more to daily peak wind velocities than to daily average velocities as consistent with our findings of a threshold wind velocity at approximately 7 m s(-1); (ii) greater erodibility in burned vs. unburned shrubland as indicated by erosion thresholds, aerodynamic roughness, and nearground soil movement; and (iii) burned shrubland lost soil from intercanopy and especially canopy patches in contrast to unburned shrubland, where soil accumulated in canopy patches. Our results are among the first to quantify post-fire wind erosion and highlight the importance of accounting for finer temporal and spatial variation in shrubland wind erosion. This finer-scale variation relates to semiarid land degradation, and is particularly relevant for predictions of contaminant resuspension and redistribution, both of which historically ignore finer-scale temporal and spatial variation in wind erosion.

Single-crystal (U-Th)/He in apatite ages were determined for a suite of crystalline rock samples from the footwall to this detachment. The samples were collected from a transect parallel to the fault slip direction, and proximal to the fault zone; they show a linear decrease in age with distance, from approximately 14 to approximately 11 Ma over approximately 15 km. The age versus distance relationship is interpreted to show a slip rate of 4.2 (+1.2/-0.8) mm/yr, continuing for a period of >3 Myr. This rate is more-or-less in agreement with, but more precise than, previously published slip rates from this and other large-offset extensional detachments. Such slip rates are alarmingly high, being roughly 5-10 times faster than rates commonly observed on active structures at the Earth's surface. These rapid slip rates suggest that significant seismic hazard might be posed by some extensional structures, and they raise questions regarding the relationship between such rapidly slipping, large-offset structures and the slower, smaller offset faults that are more commonly observed at the Earth's surface.

We have investigated potential climate records in corals from Alaska, the eastern seaboard of Canada and the United States, and a Southern Ocean (Pacific sector) seamount. Temperatures at these sites range from 4 to similar to 10 degree C. delta super(18)O values of the calcite show strong evidence for isotopic disequilibrium. Extraction of delta super(18)O paleotemperatures is therefore not straightforward. Sr/Ca data, analyzed by Secondary Ion Mass Spectrometry (SIMS), suggest that temperature might be a control on calcite Sr/Ca in Primnoa resedaeformis, but that growth-related kinetic effects could also be important. Based on previous super(14)C, delta super(13)C and delta super(15)N measurements, it has been suggested that particulate organic matter (POM) from the surface is an important carbon source to the polyps and the gorgonin fraction of the Primnoa skeleton. delta super(15)N and delta super(13)C of polyps and gorgonin show similar regional differences to delta super(15)N and delta super(13)C of surface POM. Polyps and contemporaneous gorgonin correlate strongly for both delta super(13)C and delta super(15)N. The influence of nutrient isotopic composition and climate and productivity variations on the isotopic composition of surface POM may therefore be recorded in gorgonin layers. These corals have very long lifespans (several centuries). The potential exists, therefore, to obtain extended records of surface productivity, deep ocean temperature and chemistry of value to climatologists and fisheries managers.

These techniques are used to probe the structure and dynamics of the heme a sub(3)-Cu sub(B) binuclear center and the coupled protein structures in response to the photodissociation of CO from heme Fe and its subsequent binding to and dissociation from Cu sub(B). Previous cryogenic (80 K) FTIR CO photodissociation difference results were obtained for cytochrome bo sub(3), the ubiquinol oxidase of Escherichia coli [Puustinen, A., et al. (1997) Biochemistry 36, 13195-13200]. These data revealed a connectivity between Cu sub(B) and glutamic acid E286, a residue which has been implicated in proton pumping. In the current work, the same phenomenon is observed using the CO adduct of bovine cytochrome aa sub(3) under cryogenic conditions, showing a perturbation of the equivalent residue (E242) to that in bo sub(3). Furthermore, using time-resolved (5 mu s resolution) step-scan FTIR spectroscopy at room temperature, we observe the same spectroscopic perturbation in both cytochromes aa sub(3) and bo sub(3). In addition, we observe evidence for perturbation of a second carboxylic acid side chain, at higher frequency in both enzymes at room temperature. The high-frequency feature does not appear in the cryogenic difference spectra, indicating that the perturbation is an activated process. We postulate that the high-frequency IR feature is due to the perturbation of E62 (E89 in bo sub(3)), a residue near the opening of the proton K-channel and required for enzyme function. The implications of these results with respect to the proton-pumping mechanism are discussed. Finally, a fast loss of over 60% of the Cu sub(B)-CO signal in bo sub(3) is observed and ascribed to one or more additional conformations of the enzyme. This fast conformer is proposed to account for the uninhibited reaction with O sub(2) in flow-flash experiments.

AN - 71437381; 11827518 AB - Cholera toxin entry into mammalian cells is mediated by binding of the pentameric B subunit (CTB) to ganglioside GM(1) in the cell membrane. We used flow cytometry to quantitatively measure in real time the interactions of fluorescently labeled pentameric cholera toxin B-subunit (FITC-CTB) with its ganglioside receptor on microsphere-supported phospholipid membranes. A model that describes the multiple steps of this mode of recognition was developed to guide our flow cytometric experiments and extract relevant equilibrium and kinetic rate constants. In contrast to previous studies, our approach takes into account receptor cross-linking, an important feature for multivalent interactions. From equilibrium measurements, we determined an equilibrium binding constant for a single subunit of FITC-CTB binding monovalently to GM(1) presented in bilayers of approximately 8 x 10(7) M(-1) while that for binding to soluble GM(1)-pentasaccharide was found to be approximately 4 x 10(6) M(-1). From kinetic measurements, we determined the rate constant for dissociation of a single site of FITC-CTB from microsphere-supported bilayers to be (3.21 +/- 0.03) x 10(-3) s(-1), and the rate of association of a site on FITC-CTB in solution to a GM(1) in the bilayer to be (2.8 +/- 0.4) x 10(4) M(-1) s(-1). These values yield a lower estimate for the equilibrium binding constant of approximately 1 x 10(7) M(-1). We determined the equilibrium surface cross-linking constant [(1.1 +/- 0.1) x 10(-12) cm(2)] and from this value and the value for the rate constant for dissociation derived a value of approximately 3.5 x 10(-15) cm(2) s(-1) for the forward rate constant for cross-linking. We also compared the interaction of the receptor binding B-subunit with that of the whole toxin (A- and B-subunits). Our results show that the whole toxin binds with approximately 100-fold higher avidity than the pentameric B-subunit alone which is most likely due to the additional interaction of the A(2)-subunit with the membrane surface. Interaction of cholera toxin B-subunit and whole cholera toxin with gangliosides other than GM(1) revealed specific binding only to GD1(b) and asialo-GM(1). These interactions, however, are marked by low avidity and require high receptor concentrations to be observed.

AN - 71887864; 12102498 AB - Reactive oxygen species (ROS), which contribute to the energy landscapes in and around cells, play numerous roles in maintaining normal cell homeostasis as components of signaling pathways. Excessively high levels of ROS, on the other hand, can lead to pronounced DNA damage and a variety of cellular responses, including cell cycle arrests, senescence, apoptosis and possibly cancer. Far less is known, however, about how supra-basal levels of ROS that can be generated in response to low doses of ionizing radiation or chemicals in the environment may bring about untoward or perhaps even beneficial cellular responses. Even so, some evidence suggests that adaptive responses that have been associated with ROS-generating stimuli can have protective effects by fundamentally altering subsequent cellular dose-response profiles to otherwise detrimental stresses. Yet, even these seemingly favorable 'adaptive' effects may have longer-term untoward consequences. Other effects that have been associated with supra-basal levels of ROS, such as enhanced states of cell proliferation, potentially could have a protective function. But again, such increases in cell growth, which may be accompanied by greater than normal ROS-mediated damage to DNA, as well may ultimately favour the expansion of cells with heritable mutations. Unfortunately, the state of the art of our current understanding of how elevated but still low-level increases in ROS that may be induced by environmental stimuli presently precluded incorporation of supra-basal ROS-associated mechanisms in predictive risk assessment models, both at the population level and at the level of individualized risk assessment.

AN - 71580512; 11942761 AB - We conducted research on the potential impacts of fluvalinate and coumaphos on honey bee, Apis mellifera L., queen viability and health. Queens were reared in colonies that had been treated with differing amounts of both fluvalinate and coumaphos. Pre- and posttreatment samples of both wax and bees were collected from all of the colonies and analyzed for total concentrations of fluvalinate and coumaphos. All queens were measured for queen weight, ovarial weight, and number of sperm in the spermathecae. The queens treated with high doses of fluvalinate weighed significantly less than low-dose or control queens, but otherwise appeared to develop normally. The highest fluvalinate concentrations were observed in the wax and queen cells of the high-dose group. The developing queens in colonies treated with as little as one coumaphos-impregnated strip for more than 24 h suffered a high mortality rate. Several of the queens showed sublethal effects from the coumaphos, including physical abnormalities and atypical behavior. The queens exposed to coumaphos weighed significantly less and had lower ovary weights than the control group queens. The highest coumaphos concentrations were observed in the queen cells and wax of the high-dose groups.

FeTi oxides also occur as phenocrysts in some Au-bearing silicic volcanic rocks. In oxidized plutons, or reduced plutons that are undersaturated with respect to sulfide, FeTi oxides likely are an important host of Au. To evaluate the volumetric importance of magnetite and ilmenite as hosts for Au in igneous rocks and hydrothermal ore deposits, it is necessary to quantify Au in FeTi oxide minerals. We used secondary-ion mass spectrometry (SIMS) to analyze magnetite and ilmenite standards implanted with (super 197) Au. Samples were sputtered with a Cs (super +) primary beam, and negative secondary ions were measured. Because of the small diameter of oxide phenocrysts in volcanic rocks, small raster size and beam-diameter are required. We used a 10-mu m diam beam rastered over an area with 50-mu m sides. To obtain sufficient background counts and optimum dynamic range, (super 197) Au (super -) counts were measured for up to 5 s per cycle. We obtained measured detection-limits (MDL) of 10 ppb Au in magnetite and 240 ppb Au in ilmenite operating in high-mass-resolution (HMR) mode (M/Delta M = 4,000 to 5,000). HMR mode was required to eliminate an interference with (super 133) Cs (super 48) Ti (super 16) O (super -) during analysis of ilmenite. The high MDL for ilmenite was due to the high inherent-Au content of the unimplanted standard. The siting of Au has important implications for both ore genesis and ore extraction. Quantification of Au in FeTi oxides may lead to more accurate mineralogical balances for hydrothermal Au deposits, as well as resolving questions regarding the partitioning of Au in silicic magmas and the behavior of Au in some magmatic-hydrothermal ore-forming systems.

By placing these two chemically different materials adjacent to one another, a self-sealing layer was formed at the interface between both wastes, isolating and immobilizing chemical constituents in the process. A series of leaching experiments were performed on each material separately to study the release behavior of the principal constituents. Radiotracer experiments were conducted to explore diffusion and reaction of constituents such as Fe super(3+) in a combined jarosite/fly ash system. A model has been developed to simulate the coupled processes of diffusion and precipitation taking into account porosity change due to pore filling by precipitates. The formation of a self-sealing isolation layer in a hypothetical jarosite/fly ash disposal site was modelled. Leaching results indicate that the release of elements from jarosite is much larger than that from fly ash, and that the highly pH dependent release of Fe, Al, and Zn was controlled by the solubility of their hydroxides. Leaching results also suggest that precipitation reactions can be expected to occur at the interface between jarosite and alkaline coal fly ash where a large pH gradient exists. Radiotracer experiments showed that accumulation of constituents occurred at the interface. Modeled Fe super(3+) profiles in layered jarosite/fly ash were well validated by experiments. Modeling results also showed that with the accumulation of constituents at the interface, a new layer with low porosity was formed. Application of this model suggests that there is a potential use to form a self-sealing layer in jarosite/fly ash co-disposal sites.

AN - 72185429; 12382702 AB - Los Alamos National Labs (LANL) has developed an etched track foil (CR-39) reader for neutron dose between 0 and 50.0 mSv. Currently, the US Department of Energy mandates general employee annual exposure not to exceed 50.0 mSv (5 rem). At LANL, due to a non-linear response at higher exposures. accepted practice only uses an Autoscan 60 system up to 3 mSv. The LITES system, however, has demonstrated linear response to 50 mSv, where the proprietary design measures the amount of laser light scattered by the etched tracks, proportional to dose. A collection of calibrated foils was counted by an Autoscan 60 and the LITES prototype, and the Autoscan 60 showed good linearity when counting exposure up to about 15 mSv, but not for higher exposures. From 0 to 50 mSv, the Autoscan 60 had a correlation coefficient of R2 = 0.941 and the LITES system had R2 = 0.991.

AN - 71682840; 12009129 AB - Eggshell quality, clutch size, sex ratio, and hatching success of western bluebirds (Sialia mexicana) and ash-throated flycatchers (Myiarchus cinerascens) were studied on a landscape-soil contaminant gradient at Los Alamos National Laboratory (LANL) in New Mexico from 1997 to 1999. A variety of contaminants (heavy metals, chemicals, insecticides, polychlorinated biphenyls (PCBs), organochlorines, and radioactive isotopes) range across different spatial scales and concentrations on LANL land. This study is an example of a monitoring program over a large area with varying degree of contamination that is used to highlight locations of concern for future research. There were two locations where the flycatcher had a lower hatching success. The bluebirds at Sandia wetland, a location of concern for PCBs. had a thinner eggshell thickness index (RATCLIFFE) and the eggs were smaller than at other locations. The flycatcher had thinner eggshells than bluebirds, which could add to sensitivity to exposure to contaminants. There was no variation in clutch size or sex ratio between locations or areas closer to contaminant release sites for both species. Percent females in the clutch ranged from 0 to 100% in the WEBL and from 33 to 67% for ATFL.

Fluoride substitutions are particularly common in 2:1 layer silicates, such as micas, illites and smectites. The brick and tile industries, which use naturally occurring clays as their primary raw materials, have devoted considerable effort to understanding fluorine evolution during firing of the raw materials due to increasingly stringent fluorine emission regulations. In order to understand fluorine evolution from ceramic raw materials, we have studied a number of phyllosilicate materials used in making bricks. X-ray powder diffraction and fluorine analyses were combined with heating experiments and thermogravimetric analysis to evaluate the chemical and structural changes taking place on heating. Fluorine remained in 2:1 layer silicates to higher temperatures than did hydroxyl, but it behaved identically to hydroxyl in the kaolinite studied. In all cases, fluorine evolution coincided with structural breakdown of the clay host. These results show that fluorine evolution will consistently occur during firing of clay raw materials, and the problems of fluorine emission cannot be readily solved by simple variations of firing temperatures or times.

Abundant mafic inclusions, which are fine-grained with vesicles in their cores, are present in the Showa-Iwojima rhyolitic lava. Inclusions with similar textures are found in Iwodake volcanic bombs but are less common than in the Showa-Iwojima lava. The major and trace element compositions of the inclusions plot along mixing lines connecting the host rhyolites with spatially and temporally associated basaltic to basaltic andesite magmas. Plagioclase phenocrysts in the inclusions have a large variation in core compositions (An (sub 42) to An (sub 96) ), and exhibit various zoning profiles and reaction textures, indicating they coexisted with melts ranging from basaltic to rhyolitic composition. Pyroxenes also exhibit a wide range in composition and a variety of zoning patterns consistent with multiple sources. These results suggest that a stratified magma chamber exists beneath the volcano, consisting of a lower basaltic layer, an upper rhyolitic layer and an episodically-present, thin middle layer of andesite. Variations in the chemistry of the Iwodake and Showa-Iwojima mafic inclusions suggest that multiple injections of very similar basaltic magma have occurred since the growth of the Iwodake dome. More extensive textural disequilibrium shows that the Showa-Iwojima rhyolites formed through more extensive interaction with mafic magma. The mafic-felsic interaction is consistent with degassing model of a magma chamber estimated by other researchers, which consists of degassing of upper rhyolitic magma by convection in a conduit and supply of a CO (sub 2) -rich volatile phase from underlying basaltic magma to the rhyolitic magma.

Selective ionization by ESI affords direct detection of neutral nitrogen compounds and carboxylic acids in petroleum without pre-chromatographic isolation. Ultra-high resolution/mass accuracy allows detailed and positive identification of acidic NSO compounds in the crude oils. Observed compositional differences reflect known crude oil properties/histories. Collectively, approximately 14,000 masses, spanning 18 different heteroatomic classes, are identified unequivocally, demonstrating the potential of ESI-FT-ICR MS for geochemical applications.

Halogen concentrations suggest that the fumarolic condensates represent mostly magmatic fluids, but that the hot springs are a mixture between magmatic fluids and meteoric water with some presence of seawater. The magmatic component is best preserved in the high-temperature fumaroles collected in 1998 and has a (super 129) I/I ratio of 756+ or -47X10 (super -15) . This (super 129) I/I ratio yields an iodine age of 15.5+ or -1.5 Ma, which is compatible with derivation of iodine from subducted marine sediments in this region. Ratios of I/Cl, and Br/Cl in the fumaroles also indicate that halides in the magmatic component were mainly derived from marine sediments subducted in the Nankai Trough. These observations suggest that recycling of subducted sediments is an active source of halides in the Satsuma-Iwojima volcanic system. The comparison of (super 129) I/I ratios obtained from fumaroles over the sampling period shows that a recent meteoric component was present in 1993, but not in 1998. This observation might reflect reorganization of the fumarolic system during this period, which expelled the more recent meteoric water from the fumarolic system after 1993. The acid hot springs on the flanks of the volcano maintain a (super 129) I isotopic signature indicative of substantial dilution of magmatic waters by mixing with old meteoric water and seawater. Fumarolic gases and hot spring waters were also analyzed for (super 36) Cl/Cl, but the measured ratios were at, or below, the detection limit of AMS, also indicating that recent contributions of Cl from meteoric water are small in the fumaroles and coastal hot springs.

Speciation of the actinides is critical for assessing environmental risks and for monitoring and controlling contaminant transport. The actinides may undergo immobilization by (co)precipitation of secondary phases or by sorption onto corroded waste packages or mineral phases, but also may be transported into the environment as molecular solution species or sorbed onto colloidal particulates. We have used a variety of spectroscopic techniques to obtain information on the speciation of the light actinides (U, Np, Pu, Am) in different environments. Through some examples, we illustrate the application of conventional and advanced ultra-sensitive speciation techniques to determine the nature of U, Np, and P species in concentrated chloride solutions, in precipitates in J-13 water from the Yucca Mountain site, and at the solid-solution interface of synthetic samples, and in contaminated soil samples from the Rocky Flats Environmental Technology Site.

Among the multiple constituents of radioactive waste, the actinide elements are of major importance due to their long half-lives of hundreds to hundred thousands of years, their radiation emission, and their toxicity for human health. In order to predict the environmental risk and release rates of actinides and to design meaningful remediation strategies, it is critical to understand the geochemical reactions actinides may undergo when being transported by natural (ground-and surface) waters into the environment. The range of potential reactions in natural aquifer systems is extremely broad because of the great variety of chemically active compounds in nature and the rich chemistry actinide elements exhibit. The light actinide elements, U, Np, Pu, and americium, can exist in multiple oxidation states, III-VI, with each forming behaviorally distinct molecular species that can differ by orders of magnitude in reactivity, stability, and solubility. The conditions of the aquifer, such as pH, redox potential (Eh), complexant concentrations, and colloid concentration, determine the predominant actinide species and their transport characteristics. Actinide solubility increases with the formation of the higher soluble penta- and hexavalent actinides. The geochemical processes that are most important for the actinides' fate in the environment are precipitation, complexation of dissolved species, interactions at solution-mineral interfaces, colloid formation, and the inteactions with microorganisms. These reactions are discussed for the light actinides (U, Np, Pu, and Am) in their environmentally most relevant oxidation states III, IV, V, and VI.

He based his analysis on the Green and Ampt [1911] model and treated permeability as a known function of depth. We adopt the same model to develop integro-differential equations for leading statistical moments of wetting front propagation in a three-dimensional, randomly heterogeneous soil. We solve these equations analytically for mean front position and mean pressure head gradient in one spatial dimension, to second order in the standard deviation of log conductivity. We do the same for second moments of front positions and pressure head gradient, which serve as measures of predictive uncertainty. To verify the accuracy of our solution, we compare it with the results of numerical Monte Carlo simulations.

Solutions at constant Sigma As + Sigma S of 0.1 and 0.5 mol kg (super -1) were prepared with various Sigma S/Sigma As ratios (0.1-9.0) and pH values ( approximately 7-13.2). Our data suggest that the speciation of As under the conditions investigated is more complicated than previously thought. The Raman measurements offer evidence for at least six separate S-bearing As species whose principal bands are centered near 365, 385, 390, 400, 415 and 420 cm (super -1) . The data suggest that at least two different species may give rise to bands at 385 cm (super -1) , bringing the probable minimum number of species to seven. Several additional species are possible but could not be resolved definitively. In general, the relative proportions of these species are dependent on total As concentration, Sigma S/Sigma As ratio and pH. At very low Sigma S/Sigma As ratios we also observe Raman bands attributable to the dissociation products of H (sub 3) AsO (sub 3) (aq). Although we were unable to assign precise stoichiometries for the various thioarsenite species, we were able to map out general pH and Sigma S/Sigma As conditions under which the various thioarsenite and arsenite species are predominant. This study provides a basis for more detailed Raman spectroscopic and other types of investigations of the nature of thioarsenite species.

Both the size and the form of the imaging aperture significantly affect the computational efficiency, the signal-to-noise ratio of the image, and the true amplitude information. We propose a new implementation of Kirchhoff migration with an optimized imaging aperture that is determined using migration velocity and ray incidence angle information computed directly from the data. Different from Kirchhoff migration with an artificially truncated aperture, the new method migrates a trace to a narrow region filled with specular reflection points, leading to higher computational efficiency and fewer migration artifacts. In contrast to wavepath migration, the new method smears trace energy not only to discrete Fresnel zones associated with strong reflectors, but also to the gaps among the Fresnel zones. Therefore, weak reflectors are better imaged in the new method, and the interface continuity is also improved. Numerical results with the Marmousi dataset show that the new method performs well in resolving the target anticline and revealing weak reflectors.

Conventional gel-proppant treatments and treatments using treated water and very low proppant concentrations (waterfracs) were monitored. Waterfracs have been shown to be just as effective as the conventional gel-proppant treatments in Cotton Valley reservoirs, but at greatly reduced cost (Mayerhofer and Meehan, 1998). Comparison of the seismicity induced by the two treatment types show similar distributions of event locations and focal mechanisms for common depth intervals. We interpret the induced seismicity to be primarily controlled by the natural fracture geometry and independent of treatment design. By implication, we expect the effectiveness of shear-induced fracture propping to be independent of the treatment fluid in Cotton Valley reservoirs.

The primary purpose for conducting the gravity survey was to measure small gravity anomalies due to near-surface density variations not directly associated with the cloud chamber itself. Such density variations are considered noise sources for the purposes of this study. Few published measurements of near-surface noise over underground structures exist. Those studies that have been made (Butler, 1984) have not focused upon near-surface noise, perhaps because the overall signal-to-noise ratios in such studies were relatively high. The motivation for measuring the microgravimetric noise due to near-surface density inhomogeneities is that such sources are believed to be one of the dominant sources of micro-gravimetric noise. As microgravity methods are used to detect subsurface facilities or cavities, one of the limiting factors will likely be the amplitudes and wavelengths of gravity anomalies due to naturally-occurring, near-surface density changes. Thus, measurements of such effects are required in order to estimate the utility of microgravity as a practical methodology for detecting underground facilities. Additionally, the gravity survey was planned to provide sufficient data that a model of the near-surface density structure could be calculated. Such a model, while not necessarily providing an accurate representation of the actual subsurface density distribution, would nonetheless provide a basis for modeling the vertical gravity gradient field at selected altitudes above the vicinity of the cloud chamber. Such calculations are of interest largely due to the possibility that gravity gradiometers might provide information on underground structures similar to that obtainable using gravity meters, yet operationally be much more rapid. The Cloud Chamber (CC) facility, inactive since 1968, is located in Area 2 of the NTS. In shape, the CC resembles a quonset hut; it is 43 m in length and has a semi-circular roof that is approximately 5 m high (Fig. 1). The depth from the ground surface to the top of the CC is about 5 m. The long dimension of the CC is oriented N70 degrees E, towards the site of the nuclear event HUPMOBILE, which was used as a source of ionized particles for the experiments conducted in the CC. The CC was constructed in alluvium using so-called cut-and-cover methods. Heavy equipment was used to construct a deep trench in which the CC facility was built; after construction of the CC, the materials excavated from the trench were used to backfill the trench and completely cover the CC. Despite the fact that over 9,000 gravity measurements are available in Yucca Flat, virtually no previous gravity measurements were available in the immediate vicinity (that is, within a few hundred meters) of the CC. These earlier measurements were acquired primarily to map the thickness of basin fill in Yucca Flat and are rarely spaced closer together than 40 m; the typical station spacing is about 125 m. For this reason, these earlier data can be used to estimate low-wavenumber trends, but otherwise are of little use in estimating near-surface noise at the wavelengths (10-20 m) of interest to this study.

Often a ray that traverses the shortest travel-time path does not have a significant amplitude. The success of a Kirchhoff migration scheme to correctly use multi-valued traveltime tables for such models is dependent on how the velocity/slowness model is smoothed prior to ray tracing. We investigate the relation between model smoothing and the prediction of multi-valued traveltime tables by comparing finite difference modeling of wave propagation through an unsmoothed model with wavefront construction ray tracing through models that have been smoothed in various ways. We show that oversmoothing the model leads to a loss of later arrivals predicted by the wavefront construction algorithm. We show that an optimal smoothing condition can be determined by observing the importance of later arrivals in both the raytracing and finite difference modeling. We investigate the effects of smoothing on later arrivals in a region of the Marmousi model that is not well imaged by most ray-based methods. We show that the choice of an appropriate slowness model for ray tracing leads to a significantly better image than can be obtained from an over smoothed model and that less smoothing does not enhance the image quality, in spite of its added computational cost.

It can be much more efficient than conventional finite-difference parabolic-equation schemes for a given model, and can produce images of complex structures with fewer numerical artifacts than the latter. To further improve migration accuracy, we develop a split-step Fourier Pade migration method that uses the split-step Fourier scheme followed by a split-step Pade compensation during wavefield depth extrapolation. The method is based on a new approximation to the formal solution of the one-way wave equation, rather than on the approximation to the square-root operator in the one-way wave equation. It has almost the same advantages of Fourier-transform-based migration methods, that is, it is exact in homogeneous regions, and can use a much larger grid spacing than conventional finite-difference parabolic-equation methods to produce high-quality images for large 3-D imaging problems.

The models will be made available to the research community, along with the synthetic data that are being calculated from them. These shared models have been proposed or contributed by participants in a collaborative industry, national laboratory, and university research project. The purpose of the modeling is to provide synthetic data to better understand elastic wave propagation and the effects of structural and stratigraphic complexities. The 2-D models are easier to design and change and synthetic calculations can be run relatively quickly in them. It will be possible to alter their layer properties and calculate time-lapse data sets from them. Field data will be available to accompany many of the 2-D models. 3-D models are more realistic, but more difficult to design and change. They also require considerably more computing resources to calculate synthetic data from them. A new 3-D model is being designed, and will be used for computing synthetic elastic data.

Our analysis relies on the composite media theory, which explicitly accounts for the separate effects of material and geometric uncertainty on statistical moments of head and flux. Flow parallel and perpendicular to the layering in a composite layered medium is considered. The hydraulic conductivity of each material is lognormally distributed with a much higher mean in one material than in the other. The hydraulic conductivities of points within different materials are uncorrelated. The location of the internal boundary between the two contrasting materials is usually distributed randomly with given mean and variance. We solve the equations for (ensemble) moments of hydraulic head and flux and analyse the impact of unknown geometry of materials on the distribution of head variance.

Characterization of potential contaminant plumes at such sites is difficult, both experimentally and numerically. Simulations of water flow through fractured rock were performed to examine the penetration depth of a large pulse of water entering such a system. Construction water traced with lithium bromide was released during the excavation of a tunnel at Yucca Mountain, Nevada, which is located in an unsaturated fractured tuff formation. Modeling of construction-water migration is qualitatively compared with bromide-to-chloride ratio (Br/Cl) data for pore-water salts extracted from drillcores. The influences of local heterogeneities in the fracture network and variations in hydrogeologic parameters were examined by sensitivity analyses and Monte Carlo simulations. The simulation results are qualitatively consistent with the observed Br/Cl signals, although these data may only indicate a minimum penetration depth, and water may have migrated farther through the fracture network.

At present, the Hijiori HDR system has two reservoirs (a shallow reservoir and a deep reservoir) and four wells (SKG-2, HDR-1, HDR-2a and HDR-3) completed in high temperature granite at the site. Injection well SGK-2 is completed in the shallow reservoir, which is located at a depth of about 1,800 m. Injection well HDR-1 is completed in the deep reservoir, which is located at a depth of about 2,200 m. Both reservoirs were intercepted by production wells HDR-2a and HDR-3. From November 27, 2000 to November 15, 2001, a Long-Term Circulation Test (LTCT) was conducted with HDR-1 as an injection well, and HDR-2a and HDR-3 as production wells. Two important changes were noted during the LTCT: 1) well-head temperature at HDR-2a decreased from about 180 degrees C to about 120 degrees C; and 2) pressure in the shallow reservoir increased toward the end of the test. These data are used to evaluate the lifetime of the deep reservoir and to assess the evolution of the multi-reservoir system during long-term circulation. A simple multi-reservoir model was developed using the FEHM (Finite Element Heat and Mass transfer) code developed at Los Alamos National Laboratory. The two most important conclusions of the modeling are: 1) the production wells produce more fluid from the shallow reservoir than from the deep reservoir; and 2) a change in permeability of the deep reservoir occurred during the LTCT.

Our analysis relies on the composite media theory, which explicitly accounts for the separate effects of material and geometric uncertainty on statistical moments of head and flux. Flow parallel and perpendicular to the layering in a composite layered medium is considered. The hydraulic conductivity of each material is log-normally distributed with a much higher mean in one material than in the other. The hydraulic conductivities of points within different materials are uncorrelated. The location of the internal boundary between the two contrasting materials is normally distributed random with given mean and variance. We solve the equations for (ensemble) moments of hydraulic head and flux and analyze the impact of unknown geometry of materials on distribution of head variance. JF - Acta Universitatis Carolinae.

The prediction uncertainty can be significant when the predictions depend on uncertain system parameters. We analyze prediction uncertainties through constrained nonlinear second-order optimization of an inverse model. The optimized objective function is the weighted squared-difference between observed and simulated system quantities (flux and time-dependent head data). The constraints are defined by the maximization/minimization of the prediction within a given objective-function range. The method is applied in capture-zone analyses of groundwater-supply systems using a three-dimensional numerical model of the Espanola Basin aquifer. We use the finite-element simulator FEHM coupled with parameter-estimation/predictive-analysis code PEST. The model is run in parallel on a multi-processor supercomputer. We estimate sensitivity and uncertainty of model predictions such as capture-zone identification and travel times. While the methodology is extremely powerful, it is numerically intensive.

The solute flux is described as a space-time process where time refers to the solute flux breakthrough and space refers to the transverse displacement distribution at a control plane. The first two statistical moments of solute flux are derived using a Lagrangian framework and are expressed in terms of the probability density functions (PDFs). The method is applied to an environmental project for predicting the solute flux in the saturated zone below the Yucca Mountain project area, demonstrating the applicability of the method to complex subsurface environments.

In recent years this problem has attracted considerable attention due to its importance in many practical applications. A standard approach to dealing with aquifer's heterogeneity and ubiquitous lack of data is to treat hydraulic parameters, such as hydraulic conductivity and transmissivity, as random fields. In this stochastic framework, significant progress has been made in predicting flow and transport toward wells, and in deriving expressions for the corresponding equivalent (upscaled) parameters. The major theoretical difficulty in analyzing radial flows in heterogeneous media is that the equipotential lines (lines of constant hydraulic head) are no longer circular. Yet, most existing studies use this simplifying assumption. To demonstrate this point, we start by reviewing the existing literature. We then present a stochastic variational approach that avoids this oversimplification. This approach is further used to derive bounds for equivalent (upscaled) transmissivity.

This makeup tends to exhibit discrete and continuous variations on a variety of scales, causing hydraulic parameters to do likewise. In practice, such parameters are at best measured at selected locations where their values depend on the scale and method of measurement. The data, affected by experimental and interpretive errors, are further used in model parameterization. This paper continues on our previous development of mathematical quantification of measurement errors and error propagation. We demonstrate that geostatistical techniques used to construct permeability fields do not influence the propagation of errors. At the same time, the difference between the flow prediction based on the data corrupted by measurement errors and the flow prediction based on "true" permeability values can be significant.

Typically, the parameters entering these equations are either under-specified by data (e.g., hydraulic conductivity, macroscopic velocity) or cannot be measured on a required scale in principle (e.g., the dynamic behavior of interfacial surfaces between reacting components, pore-scale velocity). In recent decades stochastic methods, which treat such parameters as random fields, have emerged as a powerful tool for dealing with uncertainty inherent in modeling subsurface phenomena. Monte Carlo simulations and Moment Differential Equations (MDE) methods are used most often in stochastic hydrogeology. The comparative strengths and weaknesses of both approaches are well understood. By contrast, so-called PDF approaches, which are based on deriving (conditional) probability density functions for the corresponding stochastic flow and transport equations, have received virtually no attention. Yet their advantages for analyzing reactive transport are manifold. Unlike most MDE approaches, they do not linearize the governing equations and provide a natural framework for analyzing rare events that are crucial for risk assessment studies. We derive a general PDF method for advective transport of a contaminant undergoing a heterogeneous, nonlinear, chemical reaction. We further demonstrate the applicability of this approach and contrast it with MDE methods. JF - Acta Universitatis Carolinae.

The flow statistics are obtained by solving the first two moments of flow, and the mean capture zones are determined by reversely tracking the non-reactive particles released at a small circle around each pumping well. The uncertainty associated with the mean capture zones is calculated based on the particle displacement covariance for nonstationary flow fields. For comparison purpose, we also conducted Monte Carlo simulations. It has been found that our model results are in good agreement with Monte Carlo results. JF - Acta Universitatis Carolinae.

These models were used to compare the loading of the following pollutants: total suspended solids, biochemical oxygen demand, total nitrogen, total inorganic nitrogen, total Kjeldahl nitrogen, total phosphorus, copper, lead, arsenic, nickel, cadmium, and chromium. The results indicate DWF contributes approximately 10-30% of the total annual flow discharged from Ballona Creek. The annual DWF volume was fairly consistent; the variation in DWF percentage contribution was dependent on the highly variable volume of WWF. The relative contribution to the annual pollutant load varied considerably between each pollutant. In general, the DWF load was found to be significant, especially in years with lower precipitation totals. The results from this investigation have identified the relative relationship between DWF and WWF loads in the BCW and will aid in the decision-making process during the development of an integrated DWF-WWF management plan and allocation of water pollution control funds between DWF and WWF management.

The Road Map (DOE/RW-0519) effort provided a long-range plan, involving technology development, demonstration, and deployment, as well as a recommended initial effort to evaluate the technology options for five or six years. This paper summarizes the ATW Research and Development Plan currently in draft form. Technology Readiness Levels (TRLs), which are based in part on a system used by the U.S. National Aeronautics and Space Administration in determining levels of flight readiness, was developed for use in assessing and advancing technologies relevant to waste transmutation. Based on TRLs and other considerations, the Program is screening technology options and prioritizing the long-term research and development effort. A top-level schedule illustrates the efforts planned to advance the important technology options in preparation for integrated system tests.

Five simulations are presented, four of which are highly idealized situations that are meant to illustrate some of the dependencies of the model on environmental conditions. The fifth simulation consists of a fire burning in complex terrain with non-homogeneous vegetation and realistic meteorological conditions. The simulated fire behavior develops out of the coupling of a set of very complex processes and not from prescribed rules based on empirical data. This represents a new direction in wildfire modeling that we believe will eventually help decision makers and land managers do their jobs more effectively.

This study investigated the interacting effects of a nonpathogenic immunological challenge and lead shot exposure early in the development of a precocial species. Seventy-one quail (Coturnix coturnix japonica) chicks orally received either one #9 lead shot (0.05 g), four lead shots (0.2 g), or no lead at the age of 8 days. A third of each of these groups of chicks were intraperitoneally injected with either 0.075 ml of 10% chukar (Alectoris graeca) red blood cells (CRBCs), Newcastle disease virus (NDV), or a placebo oil vaccine at 13 and 35 days of age. There was no difference in the survival between any of the lead or antigen treatment groups. Lead concentrations in blood were greater for the lead-dosed groups on day 49 but not on day 128. Growth curves were approximated by Weibull functions; growth parameters did not differ between lead-treated and antigen-treated birds. CRBC antigen increases fluctuating asymmetry (FA) for primary feather five, while NDV reduced FA. Lead did not affect antibody production or cell-mediated immune response. White blood cell numbers increased 7 days after antigen injection on days 27 and 49 of age. Granulocyte numbers were significantly higher for the lead-treated quail than the control quail, and both antigen-treated groups had lower granulocyte numbers than control quail. The treatment groups of combining NDV and lead shot had an average plasma protein 14% lower than other groups. Lead shot in the highest of these doses lowered asymptotic weights, increased hematocrits, lowered plasma protein, and increased granulocyte numbers of quail.

This approach is generally viewed only as an interim strategy for the coming decades while other longer-term strategies are developed and implemented - the most important being the direct reduction of carbon emissions. We are concerned that the potential for rapid, disturbance-induced losses may be much greater than is currently appreciated, especially by the decision-making community. Here we wish to: (1) highlight the complex and threshold-like nature of disturbances - such as fire and drought, as well as the erosion associated with each - that could lead to carbon losses; (2) note the global extent of ecosystems that are at risk of such disturbance-induced carbon losses; and (3) call for increased consideration of and research on the mechanisms by which large, rapid disturbance-induced losses of terrestrial carbon could occur. Our lack of ability as a scientific community to predict such ecosystem dynamics is precluding the effective consideration of these processes into strategies and policies related to carbon management and sequestration. Consequently, scientists need to do more to improve quantification of these potential losses and to integrate them into sound, sustainable policy options.

Hybridization assays, PCR amplification, and DNA sequencing were used to determine whether pXO1 open reading frame (ORF) sequences were present in other bacilli and more distantly related bacterial genera. Eighteen Bacillus species isolates and four other bacterial species were tested for the presence of 106 pXO1 ORFs. Three ORFs were conserved in most of the bacteria tested. Many of the pXO1 ORFs were detected in closely related Bacillus species, and some were detected only in B. anthracis isolates. Three isolates, Bacillus cereus D-17, B. cereus 43881, and Bacillus thuringiensis 33679, contained sequences that were similar to more than one- half of the pXO1 ORF sequences examined. The majority of the DNA fragments that were amplified by PCR from these organisms had DNA sequences between 80 and 98% similar to that of pXO1. Pulsed-field gel electrophoresis revealed large potential plasmids present in both B. cereus 43881 (341 kb) and B. thuringiensis ATCC 33679 (327 kb) that hybridized with a DNA probe composed of six pXO1 ORFs.

Normal human lung fibroblasts (HFL-1) were irradiated with 1 cGy of alpha particles and their supernatants were transferred to unirradiated HFL-1 cells as a bystander cell model. Compared to directly irradiated cells that were not treated with supernatants from HFL-1 cells exposed to low-dose radiation, such treatment resulted in increased clonogenic survival after subsequent exposure to 10 and 19 cGy of alpha particles. Increases in protein levels of AP-endonuclease, a redox and DNA base excision repair protein, were found in the bystander cells, but not in directly irradiated cells. Supernatants from alpha -particle-irradiated cells were also found to increase the clonogenicity of unirradiated cells. These results, in conjunction with our earlier findings that supernatants from cells exposed to a low dose of alpha particles contain growth-promoting activity, suggest that this new bystander effect may be related to an increase in DNA repair and cell growth /cell cycle regulation.

We first derive partial differential equations governing the statistical moments of the flow quantities by perturbation expansions and then implement these equations under general conditions with the method of finite differences. The nonstationary stochastic model developed is applicable to the entire domain of bounded, multidimensional vadose zones or integrated unsaturated-saturated systems in the presence of random or deterministic recharge and sink-source and in the presence of multiscale, nonstationary medium features. We demonstrate the model with some two-dimensional examples of unsaturated and integrated unsaturated-saturated flows. The validity of the developed stochastic model is confirmed through high-resolution Monte Carlo simulations. We also investigate the relative contributions of the soil variabilities (K sub(S), [alpha], and n) as well as the variability in recharge Q to the pressure head variance. It is found that the pressure head variance is sensitive to these variabilities, in the order of n, [alpha], K sub(S), and Q. Though the variability of [alpha] and n is usually smaller than that of K sub(S) and Q, their effect on the pressure head variance should not be ignored.

Typically, the parameters entering these equations are either under-specified by data (e.g. hydraulic conductivity, macroscopic velocity) or cannot be measured on a required scale in principle (e.g. the dynamic behaviour of interfacial surfaces between reacting components, pore-scale velocity). In recent decades stochastic methods, which treat such parameters as random fields, have emerged as powerful tools for dealing with the uncertainty inherent in modelling subsurface phenomena. Monte Carlo simulations and moment differential equations (MDE) methods are most often used in stochastic hydrogeology. The comparative strengths and weaknesses of both approaches are well understood. By contrast, so-called PDF approaches, which are based on deriving (conditional) probability density functions for the corresponding stochastic flow and transport equations, have received virtually no attention. Yet their advantages for analysing reactive transport remain to be demonstrated. Unlike most MDE approaches, they do not linearize the governing equations and they provide a natural framework for analysing rare events that are crucial for risk assessment studies. We use a perturbation closure to derive a general PDF equation for advective transport of a contaminant undergoing a heterogeneous, nonlinear chemical reaction. We conclude by solving this equation analytically for a batch system, which allows us to comment on the convergence of the solution.

The flow statistics were obtained by solving the first two moments of flow, and the mean capture zones were determined by reversely tracking the non-reactive particles released at a small circle around each pumping well. The uncertainty associated with the mean capture zones was calculated based on the particle displacement covariance for nonstationary flow fields. For comparison, we also conducted Monte Carlo simulations. Our model results were in good agreement with Monte Carlo results.

Uranium uptake was estimated in tomato (Lycopersicon esculentum), squash (Cucurbita pepo), lettuce (Lactuca scarriola), and radish (Raphanus sativus) irrigated with Nambe well water containing <1, 150, 500, and 1200 mu g Ul super(-1). Plant uptake and human dose and toxicity associated with ingestion of water and produce and inhalation of irrigated soil related to gardening activities were evaluated. Uranium concentration in plants increased linearly with increasing U concentration in irrigation water, particularly in lettuce and radish. The estimated total committed effective dose for 70 years of maximum continuous exposure, via the three pathways to well water containing 1200 mu g Ul super(-1), was 0.17 mSv with a corresponding kidney concentration of 0.8 mu g U g super(-1) kidney.

Casing deformation has been observed in wells of the study area including the GDCF 63-29 well. An objective of the study was to determine if shallow deformation at The Geysers is manifested seismically. Near-surface microearthquake activity was monitored for a period of one year; during the latter four months, monitoring was supplemented with four surface stations to help constrain locations of shallow seismicity. Event locations occurring within about 750m of the array bottom have been determined for the 10-week period January 6 to March 16, 1999. These events are distinct from surface-monitored seismicity at The Geysers in that they occur predominantly above the producing reservoir, at depths ranging from about 220 to 1000m (600 to -180m elevation). The shallow events tend to be episodic, with relatively quiescent periods of up to three weeks occurring between swarms. Event locations show a northeast-striking trend, similar to seismicity trends mapped deeper in the reservoir, and parallel to the strike of a major surface lineaments observed over the productive field. However, clear fault or fracture planes are not resolved from the hypocenters. Composite fault-plane solutions suggest oblique reverse faulting in the overburden. The shallowest seismicity terminates near the base of a serpentine unit, a contact which is the locus of most of the well casing deformations logged in the area, suggesting that reservoir contraction is accommodated along numerous discrete faults below the serpentine, but as continuous plastic deformation in the serpentine. It is hypothesized that the resulting strain discontinuity at the base of the serpentine explains the prevalence of wellbore deformation there. The shallow, above-reservoir microseismicity is strongly correlated in time with the injection and the deeper injection-induced seismic activity occurring in the reservoir immediately below. This suggests that deep injection-induced events trigger shallower events, by a remote triggering mechanism which has been observed at a larger scale at The Geysers and elsewhere.

Seismicity data are from two arrays of 25 3-component geophone packages sited in two monitoring boreholes. From a total of 2,894 event triggers, a subset of 54 microearthquakes was chosen for their high quality seismograms and clear P and S arrivals. Arrival times were picked with a precision of 0.5 to 1.0ms, and microearthquakes were located with hypocentral uncertainties estimated as less than 10-20m. Hypocenters farthest from the injection well define a nearly horizontal tube of seismicity approximately aligned in the direction of the injection well. A simultaneous inversion of arrival times for transverse isotropic velocity structure and hypocenters yielded P-wave anisotropy of -14% and S-wave anisotropy of -2%. Thus, velocities along vertical ray paths are higher than those along horizontal paths, probably because of lithologic differences. Single-event focal mechanisms were determined for 47 events, and many of them are normal fault type. The minimum principal stress derived from the focal mechanisms is nearly horizontal and trends approximately north-south, consistent with the regional stress state. An imaging analysis of the seismograms shows the presence of strong seismic scatterers at positions that correlate with boundaries seen in the hypocenters; both features probably result from a similar set of heterogeneities.

Intermediate-frequency (0.02-0.04 Hz) fundamental-mode Rayleigh waves propagating across the basin are severely attenuated, but apparent attenuation is significantly less for both low and high frequencies. We have modeled the response of surface waves in a simplified rendition of the South Caspian Basin model of Mangino and Priestly (1998) using a hybrid normal-mode/2D finite-difference approach. To gain insight into the features of the basin that cause the anomalous surface-wave propagation, we have varied parameters of the basin model and computed synthetic record sections to compare with the observed seismograms. We have varied the Moho depth beneath the basin, the shape of the basin boundaries, the thickness and shear-wave Q of the sediments and mantle, and the water depth. Of these parameters, the intermediate-frequency surface waves are most severely affected by the sediment thickness and shear-wave attenuation. All models fail to satisfy observations for frequencies of 0.05 Hz and above, and this failure is attributed to significant 3D wave propagation effects caused by focusing and scattering of surface waves by basin structures.

Data analysis techniques and systematic errors are described in detail. Data acquired during five solar flares and during two extended "quiet Sun" periods are presented; these results sample a representative portion of the asteroid's surface. Although systematic uncertainties are potentially large, the most internally consistent and plausible interpretation of the data is that Eros has primitive Mg/Si, Al/Si, Ca/Si and Fe/Si ratios, closely similar to H or R chondrites. Global differentiation of the asteroid is ruled out. The S/Si ratio is much lower than that of chondrites, probably reflecting impact-induced volatilization and/or photo- or ion-induced sputtering of sulfur at the surface of the asteroid. An alternative explanation for the low S/Si ratio is that it reflects a limited degree of melting with loss of an FeS-rich partial melt. Size-sorting processes could lead to segregation of Fe-Ni metal from silicates within the regolith of Eros; this could indicate that the Fe/Si ratios determined by the x-ray spectrometer are not representative of the bulk Eros composition.

Elemental compositions for a number of regions on the surface of Eros have been derived from analyses of the characteristic x-ray and gamma-ray emission spectra. The NEAR XGRS detection system was included as part of the interplanetary network (IPN) for the detection and localization of gamma-ray bursts (GRBs). Preliminary results for both the elemental composition of the surface of Eros and the detection of GRBs have been obtained. In addition to the science results, the design and operation of the NEAR XGRS is considered. Significant information important for the design of future remote sensing XGRS systems has been obtained and evaluated. We focus on four factors that became particularly critical during NEAR: (1) overall spacecraft design, (2) selection of materials, (3) increase of the signal-to-noise ratio and (4) knowledge of the incident solar x-ray spectrum.

Performance of the gamma-ray spectrometer (GRS) during cruise and orbit is reviewed. The best gamma-ray data were collected on the surface of Eros after the spacecraft's controlled descent on 2001 February 12. Methods used in spectral analysis, to convert peak areas to incident photons, and photons to elemental composition are described in some detail. The elemental abundance of K and the Mg/Si, Fe/Si, Si/O and Fe/O abundance ratios were determined. The Mg/Si and Si/O ratios and the K abundance are roughly chondritic, but the Fe/Si and Fe/O ratios are low compared to expected chondritic values. Three possible explanations for the apparent Fe depletion are considered.

However, to date there have been few attempts to relate such scaling, or the lack thereof, to microscopic properties of porous media through theory. We demonstrate that when a pore network can be represented as a collection of hierarchical trees, scalability of the pore geometry leads to scalability of conductivity. We also derive geometrical and topological conditions under which the scaling exponent takes on specific values 1/2 and 3/4. The former is consistent with universal scaling observed by Neuman [1994], while the latter agrees with the allometric scaling laws derived by West et al. [1997].

This paper provides a perspective on the effectiveness of those efforts.

Providing time-resolved imagery over a 60 degree field of view, the new instrument captures returns at virtually all orders of scattering in a ground-based measurement. We report the first retrievals of cloud properties using this system, from measurements of a moderately opaque altostratus. Following insights from photon diffusion theory, we are able to infer the physical thickness and optical depth of the cloud layer, and, from there, obtain an estimate of the volume-averaged liquid water content. Performance of the new instrument is discussed and it is compared with other active techniques in cloud remote sensing.

Radioactive surveys found that (super 90) Sr is present in surface water and shallow alluvial groundwater environments in Los Alamos National laboratory (LANL). Colloids may influence the transport of this radionuclide in surface and groundwater environments in LANL. In this study, the authors investigated the sorption/desorption behavior of radioactive Sr on Ca-montmorillonite and silica colloids, and the effect of ionic strength of water on the sorption of Sr. Laboratory batch sorption experiments were conducted using (super 85) Sr as a surrogate for (super 90) Sr. Groundwater, collected from Well LAUZ-1 at DP Canyon and from Well J-13 at Yucca Mountain, Nevada, and deionized water, were used. The results show that 92-100% of the (super 85) Sr was rapidly adsorbed onto Ca-montmorillonite colloids in all three waters. Adsorption of (super 85) Sr onto silica colloids varied among the three waters. The ionic strength and Ca (super 2+) concentration in groundwater significantly influence the adsorption of (super 85) Sr onto silica colloids. Desorption of (super 85) Sr from Ca-montmorillonite colloids is slower than from silica colloids. Desorption of (super 85) Sr from silica colloids was faster in LAUZ-1 groundwater than in J-13 groundwater and deionized water. The results suggest that clay and silica colloids may facilitate the transport of Sr along potential flowpaths from DP Canyon to Los Alamos Canyon.

The asymmetric contact aureole, which extends nearly 6 m above and 4 m below the intrusion, contains the metamorphic minerals, diopside, pectolite, fluor-apophyllite, fluorite, and garnet. A series of coupled heat and mass transport calculations was undertaken to provide thermal constraints for the aureole, in the absence of robust geothermometric assemblages, and insights into accompanying mass transport associated with the sedimentary rock-dike system. Calculations were completed for systems with homogeneous, anisotropic, and layered permeability, kappa . Transport, dissolution, and precipitation of silica were also incorporated into calculations. All systems modeled indicate that the thermal pulse waned in approximately 3 yr with a return to background temperatures in approximately 10 yr. Heat and fluid transport produce maximum temperature isotherms that are distinctly different in spatial extent and lateral variability for each numerical system. The homogeneous kappa case produced isotherms that pinch and swell vertically above the dike and have large lateral variations, in contrast to the anisotropic kappa case that produced a single large plume above the dike. The layered system kappa case produced the most spatially extensive thermal aureole, unlike that recorded in the rocks. Addition of dissolved silica to the flow system significantly impacts the calculated transport of heat and fluid, primarily due to density changes that affect upwelling dynamics. Although precipitation and dissolution of SiO (sub 2) can affect flow through the feedback to permeability, kappa changes were found to be minor for these system conditions. Where kappa decreased, flow was refocused into higher kappa zones, thus mitigating the kappa differences over time. This negative feedback tends to defocus flow and provides a mechanism for lateral migration of plumes. Coupled heat and silica transport produces a complex isotherm geometry surrounding the intrusion due to formation of upwelling and downwelling plumes and lateral translation of plumes, leading to variability in the isotherm pattern that does not reflect the inherent heterogeneity of the initial material properties. Initial heterogeneities in kappa are not a prerequisite for the development of a complicated flow and transport pattern. In addition, if isotherms reflect isograds, these calculations demonstrate that isograds may not form uniform structures with isograd boundaries characterized by their distance from the heat source.

These data are used to reconstruct ventilation ages, both at present and at the end of the last glacial period approximately 16500 years ago. We apply an improved two-component mixing approach to correct uranium-series dates for contaminant thorium and protactinium present in oxide coatings. Calculated seawater radiocarbon values for contemporary samples decrease with depth in the water column and agree with direct seawater radiocarbon measurements for this area. This indicates that deep-sea corals can accurately record seawater radiocarbon distributions. Two of three glacial samples experienced open-system uranium-series systematics, however, a third sample from the Drake Passage yields concordant thorium and protactinium dates as well as seawater values for initial (super 234) U/ (super 238) U. This coral yields a ventilation age that is approximately 20-40% greater than modern values for its location. This increase is consistent with published deep-sea coral and calibrated planktonic-benthic foraminifera radiocarbon data, suggesting that the glacial oceans as a whole may have been substantially less ventilated, presumably due to decreased formation of North Atlantic Deep Water. An overall decrease in oceanic mixing rates could have contributed to lower dissolved carbon in surface ocean water and lower atmospheric pCO (sub 2) during the past glacial period.

While the technical aspects of collection, injection and formation of a relatively stable carbon dioxide fluid in the rock pore space are essential to storage, the stability of the containment interface is also critical to long-term sequestration. However, the reactive behavior of carbon dioxide under reservoir conditions is largely unknown. Key reaction conditions and components include temperature, pressure, brine and liquid composition, and minerals. We are continuing to experimentally model the chemical components and reactive behavior of a reservoir-aquitard system. Our experiments employ a flexible cell hydrothermal apparatus consisting of a gold reaction cell within a rocking autoclave. The aquifer is a synthetic arkose (potassium feldspar+oligoclase+quartz+biotite), the aquitard is argillaceous shale, and the brine has an ionic strength of 5.5 molal. After reaction to steady state between brine and minerals at 200 C and 200 bars, carbon dioxide was injected into the system and the experiment continued for 80 days. Ca, Mg, Br, and SO4 decreased in the steady state CO2-brine-arkose-shale system relative to the CO2-free system, whereas K increased. A pressure decrease of 26 bars occurred in the experimental cell over a 3-day period following carbon dioxide injection. Pressure was stable afterwards. The pressure decrease is interpreted as consumption of supercritical carbon dioxide fluid by dissolution in brine and subsequent precipitation as carbonate mineral. SEM and XRD examination of the solids showed euhedral magnesite as a reaction product. Two distinctive morphologies of magnesite were present. SEM analysis also indicates the shale was being consumed by reaction. The experimental reactions provide initial constraints on mineral reactions that may impact the containment interface in moderate temperature brine aquifer systems with potential for carbon sequestration.

Fully hydrated laumontite contains 4.5 moles of H2O per formula unit of 12 framework O (pfu); 3 are located on W2 and W8, 1 on W1 and 0.5 on W5. Hydration/dehydration equilibria between laumontite and water vapor were investigated by TGA and XRD under controlled PH2O to characterize the properties of water on the W1 and W5 sites. Reversed isothermal TGA experiments at 24 degrees C showed that hydration/dehydration occurs in discrete steps; between 0 and 4 mbar PH2O, 0.4 H2O pfu are gained/lost, and between 19.5 and 24 mbar PH2O 0.8 H2O pfu are gained/lost. Hydration/dehydration is reversible at 0 to 4 mbar PH2O but exhibits hysteresis at 19.5 to 24 mbar PH2O. Rietveld crystal structure refinements using XRD patterns collected at 0.7, 16, and 40 mbar PH2O confirmed that the hydration/dehydration step between 0 and 4 mbar PH2O involves only the W5 site and that the hydration/dehydration step at 19.5 to 24 mbar PH2O involves only the W1 site. XRD experiments under variable PH2O showed that changes in the crystal structure associated with the loss/gain of water on the W5 site are continuous but those associated with the loss/gain of water on the W1 site are discontinuous. Unit-cell refinement using XRD patterns collected during the hydration of W1 confirms the presence of two laumontite phases in the sample, one with unit-cell consistent with an empty W1 site, and the other one consistent with a nearly fully occupied W1 site. Water adsorption isotherms between 0 and 30 mbar PH2O were collected at 41.1, 60.8 and 80.5 degrees C. These isotherms exhibited "reversed" hysteresis. Hydration/dehydration under these conditions involved water on W5 only. These isotherms were fitted with the Langmuir equation and a single parameter mixing model to account for excess energy of mixing. The results constrain the thermodynamic properties of the water adsorption reaction on W5 allowing evaluation of the thermodynamic properties of zeolitic water on that site. The enthalpy associated with hydration of the W5 site is more negative than that of the W1 site by approximately 7 KJ/mole of H2O, and less negative than that for the W2, W5, and W8 by approximately 26 KJ/mole of H2O (c.f. Kiseleva et al., 1996). Our results predict that the W5 occupancy decreases from approximately 85% at 100 degrees C to approximately 70% at 200 degrees C at hydrothermal conditions.

Pools and drips from these caves provide vadose-zone water samples of sufficient volume to enable stable isotope (H-2, C-13, O-18) and radioisotope (H-3, C-14, Cl-36) analyses. Our results provide new evidence on the nature of flow and transport processes in arid-region vadose zones. Our previous research in Lechuguilla Cave (Carlsbad Caverns National Park, NM) revealed elevated levels of chlorine-36 associated with atmospheric nuclear testing in the 1950s in all near-surface pools, but only a few isolated deep pools. The deep occurrences indicate isolated fast paths for infiltration through the vadose zone, apparently associated with structural features and surface topography. In contrast, fallout-associated tritium is ubiquitous throughout Lechuguilla, indicating significant vapor-phase transport. Since then, we have analyzed Lechuguilla water samples for carbon-14, and collected pool and drip samples from Carlsbad Cavern (Carlsbad Caverns National Park, NM) and Wind Cave (Wind Cave National Park, SD) for isotope analysis. Although Carlsbad and Lechuguilla are near each other, of similar scale and similar geologic setting, Carlsbad has a large natural entrance that allows evaporation and atmospheric exchange to occur throughout much of the cave while Lechuguilla has no natural entrance. This difference is reflected in markedly different isotopic signatures between the two caves. Wind Cave is located in the Black Hills, a markedly different geologic, structural, and speleogenetic environment than the Guadalupe Mountains. Samples collected in June 2001 are currently being analyzed, and will be compared to Lechuguilla and Carlsbad results.

HE concentrations in surface soils ranged up to 137 000 ppm HMX, 118 000 ppm RDX, and 102 000 ppm TNT. HE in waters range to 160 ug/L HMX, 818 ug/L RDX and 7.41 ug/L TNT. HE in water is present in springs, surface waters, alluvial waters and deep perched (>700 ft. depth) and possibly regional (>1200 ft. depth) groundwaters. HE has migrated further than would be predicted using porous flow models with observed values of volumetric moisture content and unsaturated hydraulic conductivities. Drilling results, spring flow data, stable isotope data, pore-water anion profiles, and contaminant data suggest a hydrogeologic conceptual model in which fast pathways such as fractures and surge beds facilitate contaminant transport within the UBT vadose zone. HE ratios, particularly RDX/HMX, may provide insights into the sources and vadose-zone transport of contaminants in the subsurface. Older, cast explosives contain higher proportions of TNT and RDX than do modern plastic bonded explosives. Both RDX and HMX behave conservatively during transport; they have similar retardation factors. Their ratio will be minimally effected by differential retardation during flow. SWSC spring has statistically higher RDX/HMX than Burning Ground and Martin springs. However, the RDX/HMX of the latter two springs is quite similar to the solubility ratio of RDX/HMX, suggesting buffering of this ratio by solid HE. This observation also suggests differing mixtures of contaminant sources for the former spring than the latter two springs. Surprisingly, spring flow, stable isotopes, and major element chemistries show similarities between SWSC and Burning Ground springs. Deep groundwater RDX/HMX is fairly constant in the regional aquifer whereas the overlying perched zone shows heterogeneous values. HE sources and flow paths to deep groundwaters also appear heterogeneous.

However, only limited measurements at a few locations are usually available. This combination of significant spatial heterogeneity with incomplete information about it leads to uncertainty about the values of formation properties and thus, to uncertainty in flow and transport prediction. The theory of stochastic processes provides a natural method for quantifying these uncertainties. During the last three decades, many stochastic models have been developed for this purpose. In most of these models, the assumption of stationary (statistically homogeneous) medium properties and flow, among other simplifying ones, is invoked. In the vadose zone or an unsaturated-saturated system, the requirement of flow stationarity is always violated because the presence of water table boundary renders the flow highly nonstationary (local dependent). In this presentation, we describe recently developed nonstationary stochastic models for flow and solute transport and discuss the impacts of flow nonstationarity on uncertainty quantification for the following scenarios: the gravity-dominated flow, unsaturated flow with the water table boundary, and a saturated-unsaturated flow. We also report the results of comparing such nonstationary models with Monte Carlo simulations.

We compare the observed temperature-reflectance relationships with those predicted using a rough-surface numerical model with varying albedo. The lunar surface response in different highland and mare locations is explored as a function of varying phase angle. At very low phase angles the temperature and reflectance response is primarily governed by the variation in single-scattering albedo regardless of the presence of topography. As the phase angle increases, the influence of surface roughness grows. Finally, at moderate to high phase angles the effect of surface roughness dominates. In the absence of large-scale topography the lunar surface temperature and reflectance response at all phase angles is governed by the variation in single-scattering albedo. LWIR-measured temperature variations yield local topographic information at high incidence angles that is unavailable via the reflectance, while UVVIS-measured reflectance variations yield local topographic information at low incidence angles that is unavailable via the temperature.

Although the site is arid, previous studies indicate net infiltration rates of 5-10 mm yr (super -1) under current climate conditions. Unsaturated flow of water through the mountain generally is vertical and rapid through the fractures of the welded tuffs and slow through the matrix of the nonwelded tuffs. The vitric-zeolitic boundary of the nonwelded tuffs below the potential repository, where it exists, causes perching and substantial lateral flow that eventually flows through faults near the eastern edge of the potential repository and recharges the underlying groundwater system. Fast pathways are located where water flows relatively quickly through the unsaturated zone to the water table. For the bulk of the water a large part of the travel time from land surface to the potential repository horizon ( approximately 300 m below land surface) is through the interlayered, low fracture density, nonwelded tuff where flow is predominately through the matrix. The unsaturated zone at Yucca Mountain is being modeled using a three-dimensional, dual-continuum numerical model to predict the results of measurements and observations in new boreholes and excavations. The interaction between experimentalists and modelers is providing confidence in the conceptual model and the numerical model and is providing researchers with the ability to plan further testing and to evaluate the usefulness or necessity of further data collection.

To test the proposed hypothesis that coulombic forces between water-soluble polymers and enzymes are primarily responsible for enzyme stabilization, we examined the catalytic stability and activity of two enzymes in the presence of polymers differing in net charge. All polymers tested increased enzyme lifetimes, regardless of their net charge, suggesting that stabilization of these enzymes by water-soluble polymers is not solely dependent on simple electrostatic interactions between the polymers and enzymes.

AN - 72186679; 11591152 AB - We investigated the characteristics of CRP having amino acid substitutions at position 99. Analysis of amino acid residue proximity to cAMP in molecular dynamics (MD) simulations of the CRP:(cAMP)(2) complex [García, A. E., and Harman, J. G. (1996) Protein Sci. 5, 62-71] showed repositioning of tyrosine 99 (Y99) to interact with the equatorial exocyclic oxygen atom of cAMP. To test the role of Y99 in cAMP-mediated CRP activation, Y99 was substituted with alanine (A) or phenylalanine (F). Cells that contained the WT or mutant forms of CRP induced beta-galactosidase in the presence of cAMP. Purified WT, Y99A, and Y99F CRP showed only a 3- to 4-fold difference in cAMP affinity. There were no apparent differences between the three forms of CRP in cAMP binding cooperativity, in CRP:(cAMP)(1) complex binding to lacP DNA, in the formation of CRP:cAMP:RNAP complexes at lacP, or in CRP efficacy in mediating lacP activity in vitro. The apo-form of Y99A CRP was more sensitive to protease than the apo-form of either WT CRP or Y99F CRP. Whereas the WT or Y99F CRP:(cAMP)(1) complexes were cleaved by protease at hinge-region peptide bonds, the Y99A CRP:(cAMP)(1) complex was cleaved at peptide bonds located at the subunit interface. The rates of subunit exchange for Y99A CRP, both in the apo-form and in a 1:1 complex with cAMP, were significantly greater than that measured for WT CRP. The results of this study show that tyrosine 99 contributes significant structural stability to the CRP dimer, specifically in stabilizing subunit association.

In these experiments, we compare the sensitivity of a poly(dimethylsiloxane) (PDMS) membrane and an allyl alcohol (AA) membrane to the detection of methanol. In MIMS, the membrane serves as the interface between the sample and the vacuum of the mass spectrometer. Membrane-diffused water was used as the reagent ion (H sub(3)O super(+)) for chemical ionization of methanol in an ion trap mass spectrometer. Linear calibration curves have been obtained for methanol using both PDMS and AA membranes. For PDMS, detection limits of methanol are 14 ppmv and 5 ppm in air and water, respectively. For AA, detection limits are 3.3 ppmv and 2 ppm in air and water, respectively. We demonstrate that the sensitivity of the analysis can be altered by the chemistry of the membrane. When the AA membrane is used, the sensitivity of MIMS is enhanced over that of PDMS by a factor of 8.5 for methanol in air and by a factor of 23.4 for methanol in water.

AN - 71211971; 11580284 AB - We have used site-directed mutagenesis, flow dialysis, and Fourier transform infrared (FTIR) spectroscopy to study Ca(2+)-binding to the regulatory component of calcineurin. Single Glu-Gln(E --> Q) mutations were used to inactivate each of the four Ca(2+)-binding sites of CnB in turn, generating mutants Q1, Q2, Q3, and Q4, with the number indicating which Ca(2+) site is inactivated. The binding data derived from flow dialysis reveal two pairs of sites in the wild-type protein, one pair with very high affinity and the other with lower affinity Ca(2+)-binding sites. Also, only three sites are titratable in the wild-type protein because one site cannot be decalcified. Mutation of site 2 leaves the protein with only two titratable sites, while mutation of sites 1, 3, or 4 leave three titratable sites that are mostly filled with 3 Ca(2+) equiv added. The binding data further show that each of the single-site mutations Q2, Q3, and Q4 affects the affinities of at least one of the remaining sites. Mutation in either of sites 3 or 4 results in a protein with no high-affinity sites, indicating communication between the two high-affinity sites, most likely sites 3 and 4. Mutation in site 2 decreases the affinity of all three remaining sites, though still leaving two relatively high-affinity sites. The FTIR data support the conclusions from the binding data with respect to the number of titratable sites as well as the impact of each mutation on the affinities of the remaining sites. We conclude therefore that there is communication between all four Ca(2+)-binding sites. In addition, the Ca(2+) induced changes in the FTIR spectra for the wild-type and Q4 mutant are most similar, suggesting that the same three Ca(2+)-binding sites are being titrated, i.e., site 4 is the very high-affinity site under the conditions of the FTIR experiments.

Geol. 132 (1996) 25; Geochim. Cosmochim. Acta 64 (2000) 1363]) has shown that an aerobic Pseudomonas mendocina bacterium enhances Fe(hydr)oxide dissolution in order to obtain Fe under Fe-limited conditions. The P. mendocina is incapable of utilizing Fe as a terminal electron acceptor and requires several orders of magnitude lower Fe concentrations than do dissimilatory Fe reducing bacteria. The research reported here compared the effects of the P. mendocina on dissolution of well and poorly ordered Clay Minerals Society Source Clay kaolinites KGa-1b and KGa-2, respectively, under Fe-limited conditions. KGa-1b and KGa-2 contain 0.04 and 0.94 bulk wt.% Fe, respectively, and their surface Fe/Si atomic ratios = 0.008 and 0.012. Following strong cleaning of the kaolinites in 5.8 M HCl at 85 degrees C, the surface Fe/Si atomic ratios decreased to 0.004 and 0.008, respectively. Both kaolinites also developed a Si-enriched surface precipitate upon strong cleaning. Because the P. mendocina take up Fe, we could not measure Fe release from the kaolinite directly, but rather had to monitor it indirectly by comparing microbial populations sizes under Fe-limited growth conditions. We found that microbial growth on uncleaned, weakly cleaned, and strongly cleaned kaolinites increased with the amount of Fe readily available to organic ligands as estimated by dissolution in 0.001 M oxalate (pH 3). This suggests that it is the amount of readily accessible Fe that controls Fe acquisition and hence microbial growth. The trend is based on only a relatively small range of kaolinite Fe contents, and the research thus needs to be expanded to include kaolinites with a broader range of bulk and surface Fe concentrations. Significant enhancement of Al release was observed in the presence of the bacteria, along with generally some enhancement of Si release. This enhancement of kaolinite dissolution could be related to an observed pH increase from approximately 7-8 to approximately 9 in the presence of the bacteria and/or to production of Al chelating agents. The P. mendocina produce a variety of organic exudates, including siderophores [Chem. Geol. 132 (1996) 25; Geomicrobiology (2001b)], and further studies into the effects of the siderophores on Al complexation and on kaolinite dissolution are ongoing.

The use of combined quantitative X-ray diffraction and geochemical analysis allows measurement of the chemical changes that accompanied open-system zeolitization at Yucca Mountain. This approach also provides measures of the extent of chemical migration that has occurred in these horizons as a result of subsequent cation exchange. Mass-balance analysis of zeolitized horizons with extensive cation exchange (drill hole UZ-16) and with only minimal cation exchange (drill hole SD-9) shows that Al is essentially immobile. Although zeolitization occurred in an open system, the mass transfer of constituents other than water is relatively small in initial zeolitization, in contrast to the larger scales of cation exchange that can occur after zeolites have formed. Cation exchange in the clinoptilolite + or - mordenite zeolitized horizons is seen in downward-diminishing concentration gradients of Ca, Mg, and Sr exchanged for Na and (to lesser extent) K. Comparison with data from drill hole SD-7, which has multiple zeolitized horizons above the water table, shows that the upper horizons accumulate Ca, Mg, and Sr to such an extent that transport of these elements to the deepest UZ zeolitized horizon can be blocked. Quantitative analysis of zeolite formation yields insight into processes that are implied from laboratory studies and modeling efforts but are otherwise unverified at the site. Such analysis also yields information not provided by or contradicted by some models of flow and transport. The results include the following: (1) evidence of effective downward flow through zeolitic horizons despite the low permeability of these horizons, (2) evidence that alkaline-earth elements accumulated by zeolites are mostly derived from eolian materials in surface soils, (3) validation of the very effective operation of unsaturated zeolitic horizons as cation-exchange barriers, (4) independent support of models that indicate average water infiltration rates of approximately 5 mm/yr over the past 10 Ma, and (5) evidence that the presence or absence of cation-exchange profiles can be used to identify those portions of the site where transport through the UZ is concentrated. This last point is relevant to repository design because a knowledge of where transport takes place can be used to advantage in defining the boundaries of a repository such that high-flux portions of the site can be avoided.

Different solution chemistries and pHs are found to result in differences in the equatorial coordination of the uranyl species (UO (sub 2) (super 2+) ) incorporated in the calcite, with multiple coordination environments of uranyl evident in one sample. Differences in the equatorial coordination between the aqueous uranyl species and those found in the calcite indicate that coordination changes occur during incorporation of at least some species. This contrasts with previous findings showing no change in equatorial coordination during uranyl incorporation into aragonite, and may explain the greater incorporation in this latter phase. The absence of calcium backscatterers and well defined structure beyond the equatorial shell is consistent with disorder associated with disruption of the local calcite structure. This may indicate an inability of the uranyl unit to assume a stable structural environment in the host calcite, which could decrease the stability of uranyl-containing calcite. Calcite single crystals grown in uranyl-containing solutions exhibit polygonized spiral growth hillocks on (1014) surfaces composed of four vicinal surfaces, consistent with face symmetry. Micro-X-ray fluorescence reveals that uranium is differentially incorporated between nonequivalent vicinal surfaces, reflecting step-selective incorporation of uranyl species during growth. Micro-X-ray absorption near-edge structure spectra from the nonequivalent vicinal faces fail to reveal any differences in speciation between the vicinals or that might account for the presence of the multiple coordination environments identified by luminescence and X-ray absorption spectroscopies.

In order to investigate these properties, we constructed several cold-seal hydrothermal experiments which precipitated fluorite from water-saturated haplogranitic melts over a range of alkalinity ([Na+K]/Al = 0.8-2.00). Solubility experiments were conducted at P = 100 MPa, T = 700, 800, 900, and 1000 degrees C, for 7 to 240 hours, using finely ground haplogranitic glasses mixed with fluorite powder. The diffusivity experiment, conducted at P = 100 MPa, T = 900 degrees C, for 7 to 216 hours, surrounded a single fluorite crystal with haplogranitic glass. Electron microprobe analysis (EMPA) of the solubility products (glass + crystals) documented increasing fluorite saturation with melt alkalinity. At 900 degrees C, this relationship is described by C(Fl) = 0.69XA+0.97, where A = [Na+K]/Al. Additionally, because of F loss during pre-run fusion at atmospheric pressure, Ca was enriched in run products. These small amounts (2.4-2.8 wt%) of dissolved Ca reduced fluorite solubility. While extensive feldspar crystallization in the lower-T products (700, 800 degrees C) precluded examination by EMPA, analysis of the higher-T runs (900, 1000 degrees C) yielded fluorite solubilities from 1.5 wt% (1.1 mol%) to 3.1 wt% (2.3 mol%). In the diffusivity experiment, EMPA measurement of glass adjacent to the fluorite crystal revealed concentration gradients in Ca and F. These gradients are comparable to theoretical calculations of Ca and F diffusivities (D{Ca} and D{F}, respectively). Thus, these two parameters were calculated through an error-function (C = CoXerfc(x/(4Dt) (super 1/2) )) fit of the concentration gradient at T = 900 degrees C: D{Ca} = 3.17X10 (super {-9}) cm (super 2) /sec and D{F} = 1.10X10 (super -8) cm (super 2) /sec.

Wind patterns during the summer period were more southerly than usual resulting in the hypothesis that the polynya opened due to ice advection away from the Ronne Ice Shelf and enhanced melting through the open water-albedo feedback mechanism. A numerical model is used to investigate the initiation of the polynya. A narrow polynya opens considerably in the model with the 1997-1998 winds, to the extent observed in the satellite images. Solar radiation flux is modeled to demonstrate the important role played by open water-albedo. Surface forcing is shown to be the driving force for the 1997-1998 Ronne Polynya. (Mod. auth. abstr.)

Improved spatial resolution at both poles shows that the largest concentrations of hydrogen overlay regions in permanent shade. In the north these regions consist of a heavily cratered terrain containing many small (less than approximately 10-km diameter), isolated craters. These border circular areas of hydrogen abundance ([H]) that is only modestly enhanced above the average equatorial value but that falls within large, flat-bottomed, and sunlit polar craters. Near the south pole, [H] is enhanced within several 30-km-scale craters that are in permanent shade but is only modestly enhanced within their sunlit neighbors. We show that delivery by the solar wind cannot account for these observations because the diffusivity of hydrogen at the temperatures within both sunlit and permanently shaded craters near both poles is sufficiently low that a solar wind origin cannot explain their differences. We conclude that a significant portion of the enhanced hydrogen near both poles is most likely in the form of water molecules. Copyright 2001 by the American Geophysical Union.

The parameters are combined in an easy-to-use equation that determines the fractions of the four oxidation states. Similar analyses have been applied to plutonium in other solutions, and the same methods can be applied to seawater. An appendix shows how to estimate and interpret the alpha coefficient for tetravalent plutonium using published information for tetravalent thorium.

We employed a novel fragment identification approach based on a hierarchical agglomerative clustering routine that identifies fragments in an automated fashion. No method is free of error, and we identified the major sources so that experiments can be designed to minimize its effect. Phylogenetic analysis of the fluorescent AFLP results reveals five genetic groups in these group 1 bacilli. The ATCC reference strains were restricted to two of the genetic groups, clearly not representative of the diversity in these bacteria. Both B. anthracis strains analyzed were closely related and affiliated with a B. cereus milk isolate (ATCC 4342) and a B. cereus human pathogenic strain (periodontitis). Across the entire study, pathogenic strains, including B. anthracis, were more closely related to one another than to the environmental isolates. Eight strains representing the five distinct phylogenetic clusters were further analyzed by comparison of their 16S rRNA gene sequences to confirm the phylogenetic status of these groups. This analysis was consistent with the AFLP analysis, although of much lower resolution. The innovation of automated genotype analysis by using a replicated and statistical approach to fragment identification will allow very large sample analyses in the future.

In this study a strict aerobe, Pseudomonas mendocina, was grown in batch culture with hematite, goethite, or ferrihydrite as a source of Fe. P. mendocina obtained Fe from these minerals in the following order: goethite > hematite > ferrihydrite. Furthermore, Fe release from each of the minerals appears to have occurred in excess, as evidenced by the growth of P. mendocina in the medium above that of the insoluble Fe(III) (hydr)oxide aggregates, and this release was independent of the mineral's surface area. These results demonstrate that an aerobic microorganism was able to obtain Fe for growth from several insoluble Fe minerals and did so with various growth rates.

The CO, so produced, may be converted by well-established means to a combustible fuel, such as methanol. We intend to make a future demonstration of the solar reduction of CO sub(2) based on these processes. This paper, however, addresses only the problem of preserving, or even enhancing, the initial photolytic CO by quenching the hot gas with colder H sub(2)O or CO sub(2). We present model calculations with a reaction mechanism used extensively in other calculations. If a CO sub(2) gas stream is heated and photolyzed by intense solar radiation and then allowed to cool slowly, it will react back to the initial CO sub(2) by a series of elementary chemical reactions. The back reaction to CO sub(2) can be terminated with the rapid addition of CO sub(2), water, or a mixture. Calculations show that a three-fold quench with pure CO sub(2) will stop the reactions and preserve over 90% of the initial photolytic CO. We find that water has one of two effects. It can either increase the CO level, or it can catalyze the recombination of O and CO to CO sub(2). The gas temperature is the determining factor. If the quench gas is not sufficient to keep the temperature below approximately 1100 K, a chain-branching reaction dominates and the reaction to CO sub(2) occurs. If the temperature stays below that level a chain terminating reaction dominates and the CO is increased. The former case occurs below approximately a fourfold quench with a water/CO sub(2) mixture. The later case occurs when the quench is greater than fourfold. We conclude that CO sub(2), H sub(2)O, or a mixture may quench the hot gas stream photolyzed by solar radiation and preserve the photolytic CO.

But the general nature of such adaptive steps is still unclear. Evolution is often thought to be random and dependent on unpredictable events. In this light, one might expect the steps taken by adaptation to be completely random, both biologically and temporally. Here I present a mathematical derivation to show that, on the contrary, adaptive steps can have fairly strong rhythm. I find that the strength of the adaptive rhythm, that is its relative temporal regularity, is equal to a constant that is the same for all microbial populations. As a consequence, numbers of accumulated adaptations are predicted to have a universal variance/mean ratio. The theory derived here is potentially applicable to the study of molecular evolution.

AN - 71108512; 11513459 AB - Maintaining regular documentation, such as a log-book, can be an organization's most important asset when dealing with radiation protection issues, both normal and abnormal. When an organization is faced with litigation, proper documentation of events can ensure that a record is acceptable and, by extension, that the data itself is acceptable. A record of events will not preclude litigation, nor will it guarantee that an organization will prevail in a court of law, but it will provide evidence and credibility that could favorably affect the outcome of litigation. An organization can ensure that the documents it creates and maintains are as effective as possible by being aware of the legal consequences of documenting events and taking appropriate steps to conform to standards for admission of documentation. Misconceptions about log keeping such as recording only events that are likely to result in litigation, rather than recording all events, can prevent a record from being admissible as evidence. Because of the amount of effort and time put into documentation, and the reliance placed on its contents, it is important for an organization to ensure that a record will do what it is intended to do, namely to accurately record activities. Issues discussed in this article include the legal basis of documentary evidence, what and what not to record, when and how to record it, and how to strengthen the records kept.

The deposits have been sampled in detail at a selected locality, and the following features have been analyzed: (i) maximum clast size; (ii) grain size distribution; (iii) componentry; (iv) lithic types; (v) pumice morphology; (vi) pumice types; and (vii) pumice crystal abundance. Stratigraphic variations of these features are assumed to record changes that occurred during the eruption, including changes in eruptive plume height, nature and relative efficiency of the magma fragmentation process, conduit stability, and magma flow in the conduit. Based upon the inferred temporal changes, we propose the following eruption reconstruction. The sustained Plinian column activity reached its climax (in terms of mass eruption rate and plume altitude) soon after the beginning of the eruption, and subsequently began to gradually subside. As a result of eruption waning, the conduit walls began to collapse, causing an increase in the shear stress in the flowing vesicular magma and an increase in the efficiency of the magma fragmentation process. Eventually the conduit closed or became too narrow to support a high-standing eruption column, leading to ash flow eruption as a result of the collapse of what was left of the eruptive plume, and/or directly from emission of an overpressured jet. Subsequent conduit pressure increases led to conduit re-opening and a Plinian column with associated pumice fallout began anew. The eruptive magma fragmentation process is proposed to have been of a brittle nature and linked to the shear stress generated by conduit wall friction. Fragmentation efficiency is recorded by grain size distributions and free crystal contents of the deposits.

Of particular interest is the occurrence of increasing pressure amplitude and decreasing phase lags observed at several deep stations. The pressure amplitude increases by 13% and the pressure peak arrives 65 to 72 h earlier as the depth of the unsaturated zone increases from 407 to 436 m. This observation is inconsistent with a conventional 1D downward pressure decay model, but can be explained by hypothesizing the existence of a lateral pneumatic flow path from a nearby fault. A 2D numerical model has been constructed to test this lateral flow hypothesis. The modeling results indicate that a leaky-fault hypothesis can reconcile the measured barometric data with other geologic mapping and permeability measurements at the site. The inferred fault permeability ranges from 0.6X10 (super -12) to 0.12X10 (super -9) m (super 2) , and that of the surrounding tuff layers ranges from 0.4X10 (super -13) to 0.8X10 (super -12) m (super 2) . Our analysis also demonstrates that although the larger-amplitude, longer-period synoptic signals lack coherence and periodicity, determination of air permeability in deep unsaturated zones must rely on these longer-period oscillations of barometric pressure whose periods are on the order of weeks to months because the shorter-period diurnal and semidiurnal barometric oscillations generally are not detectable at deep depths.

The study was conducted in the vicinity of the Idaho National Engineering and Environmental Laboratory (INEEL), Idaho, which has a long history of storing and disposing of radioactive waste, some of which has entered the aquifer.Uranium concentrations in INEEL groundwater range from 0.3 to 3.6 ppb, and super(234)U/ super(238)U atomic ratios range between 0.000085 and 0.000168 (activity ratios of 1.5 to 3.1). All of the samples have natural super(235)U/ super(238)U ratios, and super(236)U was not detected; thus, the trends delineated by the super(234)U/ super(238)U ratios reflect natural variations in the aquifer. Groundwater nearest the valleys that provides focused recharge to the Snake River Plain aquifer from the northwest has high super(234)U/ super(238)U ratios when compared to values of regional groundwater flowing southwestward in the aquifer. Mixing of these water masses can account for the intermediate uranium isotope ratios of some of the samples; however, water-rock interaction must also be invoked to account for the observed trends in isotopic data. Uranium and super(87)Sr/ super(86)Sr isotope ratios are positively correlated and define a trend toward isotope ratios of the aquifer host rock. These relations indicate that dissolution and/or ion exchange are more important than alpha recoil or selective leaching in controlling super(234)U/ super(238)U ratios. As a result, super(234)U/ super(238)U ratios decrease along flow pathways toward the secular equilibrium values of the aquifer host rock. Uranium and strontium isotopic modification can be explained by incongruent dissolution of the host basalt.Lateral distributions of super(234)U/ super(238)U ratios indicate elongate zones of high super(234)U/ super(238)U ratios extending southward from the mouths of Birch Creek and the Little Lost River. These elongate zones are interpreted as preferential flow paths. Two isolated pockets of groundwater located in the central and western parts of the study area have lower super(234)U/ super(238)U ratios than the adjacent aquifer water. Both of these zones are interpreted to contain stagnant waters that are relatively isolated from flow in the regional aquifer due to lower permeability. Physical and chemical evidence strongly suggests that the stagnant zones are dominated by water from the Big Lost River that infiltrated via flood control ponds (spreading areas), playas, and the riverbed.

Since the discovery of plate tectonics, it has been widely conjectured but only recently demonstrated that this peculiar style of convection may be facilitated by an upper mantle low viscosity zone (LVZ) over which the plates glide easily. The LVZ, or "asthenosphere", concept dates from 19th century investigations of isostatic support of mountain belts and is supported by modern evidence for a seismic low velocity zone and by studies of postglacial rebound and dynamic compensation of the Earth's gravity field. Here we show in both two-dimensional (2-D) Cartesian and 3-D spherical Earth models that combining a pronounced LVZ and a plastic yield stress to allow localized weakening of the cold thermal boundary layer results in a distinctly plate tectonic style of convection, with approximately 30% toroidal surface motion for the 3-D case. Recycling of water into the upper mantle at subduction zones is a plausible cause of Earth's LVZ, whereas Venus is dry and lacks both an LVZ and plate tectonics.

A distinguishing feature of CBD is beryllium hypersensitivity, which can be measured in vitro by a lymphocyte proliferation test. The objective of this study was to determine whether certain allelic variations of the HLA-DPB1 gene, which had been observed previously in CBD, could be found in a group of individuals having beryllium hypersensitivity, but no symptoms of CBD. A flow cytometry-based Lymphocyte Proliferation Test combined with immunophenotyping (Immuno-LPT) was used to detect CD4 + and CD8 + T cell proliferation in response to in vitro stimulation with beryllium. The HLA-DPB1 haplotypes of the same individuals were determined by automated DNA sequencing. Twenty-two out of 25 beryllium-sensitive, non-CBD individuals were found to be carriers of the HLA-DPB1 gene having a substitution of a glutamic acid at position 69 in Exon 2 (Glu69), and a significantly high percentage (24%) were Glu69 homozygotes. Most of the CD4 + responders on the Immuno-LPT (10/14) carried rare, non-*0201 Glu69 DPB1 alleles; while most of the non-CD4 + responders (9/11) were common Glu69 carriers (*0201 or *0202) or non-Glu69 individuals (non-Glu69/non-Glu69). This is the first direct evidence that HLA-DP genotype is linked to a phenotypic response that occurs in beryllium sensitization in the absence of clinical CBD.

Simulations were performed using the HOTMAC boundary-layer meteorological model using a 1, 2, 4 and 8-km horizontal grid size nested mesh system. Investigation of the vertical structure and evolution of the atmospheric boundary layer for the August 12-14 time period is emphasized in this paper due to its suspected importance in precipitating the ozone episode. This period was characterized by a slowly-evolving high pressure system over the region, a persistent upper-level jet at 2500-3500 in above ground level (agl), deep daytime mixed layer heights of 3500 m depth and unusually deep nighttime stable layers extending up to 2500 m above the ground. The fact that the boundary-layer growth stalled on the morning of August 13 relative to that on August 12 has been suggested as a possible reason for the ozone episode on the 13th. In addition, relatively weak surface-level winds were measured on August 13. Using both model results and experimental data we hypothesize explanations for the slower mixed-layer growth on the morning of the 13th and the stronger surface-level winds found on the 12th and 14th.

Effective basin-scale permeabilities of selected Powder River basin aquifers and aquitards were calibrated by matching surface heat flow measurements to simulation results. Fractures associated with a large anticline in the southwestern part of the basin were found to play a major role in the basin's thermal regime. While the model results are non-unique, they demonstrate that regional structural features play an important role in a basin's overall energy budget and fluid flow regime. With the results of the basin-scale model it is possible to evaluate regional-scale flow and transport processes. Copyright 2001 by the American Geophysical Union.

AN - 71053556; 11478246 AB - Uptake of plutonium and uranium mediated by the siderophore desferrioxamine-B (DFOB) has been studied for the common soil aerobe Microbacterium flavescens(JG-9). M. flavescens does not bind or take up nitrilotriacetic acid (NTA) complexes of U(VI), Fe(III), or Pu(IV) or U(VI)-DFOB but does take up Fe(III)-DFOB and Pu(IV)-DFOB. Pu(IV)-DFOB and Fe(III)-DFOB accumulations are similar: only living and metabolically active bacteria take up these metal-siderophore complexes. The Fe(III)-DFOB and Pu(IV)-DFOB complexes mutually inhibit uptake of the other, indicating that they compete for shared binding sites or uptake proteins. However, Pu uptake is much slower than Fe uptake, and cumulative Pu uptake is less than Fe, 1.0 nmol of Fe vs 0.25 nmol of Pu per mg of dry weight bacteria. The Pu(IV)-DFOB interactions with M. flavescens suggest that Pu-siderophore complexes could generally be recognized by Fe-siderophore uptake systems of many bacteria, fungi, or plants, thereby affecting Pu environmental mobility and distribution. The results also suggest that the siderophore complexes of tetravalent metals can be recognized by Fe-siderophore uptake proteins.

Thus far, efforts toward cooperation have met with some limited success, the aims the dismantling of much of the post-Soviet nuclear infrastructure & the securing of storage sites. However, the political & economic turmoil in Russia continues to hinder nuclear downsizing; moreover, Russia's relationship with the US is ambiguous. Putting forth a hierarchy of risks, the author advocates nuclear cooperation with Russia; top priority is given to the avoidance of nuclear exchange. Other concerns include the risk of theft or diversion of weapons & nuclear materials; technology exportation & inadvertent leakage of scientific knowledge; the sheer size of the post-Soviet arsenal & plethora of potential materials. The author then offers a series of proposals promoting nuclear cooperation with Russia that address both the imminent & long-term interests of both countries. The Bush administration needs to pursue cooperation intensely -- to proceed on the assumption that Russia is an ally rather than a foe. 1 Table, 1 Appendix. K.

Volcanic CO (sub 2) is trapped beneath a tens of meters thick temperature inversion at night and produces excess CO (sub 2) mixing ratios of up to tens of ppm above background. Measurements of the excess CO (sub 2) , as a function of height above the ground, and wind direction are combined with the downslope wind speed to estimate the total flux of CO (sub 2) trapped near the ground, which provides a minimum estimate of the total volcanic emissions. The CO (sub 2) emissions were greatest shortly after each eruption and then decreased exponentially with 1/e time constants of 6.6, 6.5, and 1.6 years for the post-1950, 1975, and 1984 periods. Total emissions for these periods were 3.3, 1.9, and 2.5X10 (super 8) kg, respectively. The distribution of quiescent volcanic CO (sub 2) with wind direction shifted eastward after the 1975 and 1984 eruptions by a few degrees, coinciding with a shift in eruptive activity from the SW rift (1950) to the NE rift (1984). A broadening of the distribution in 1993-1995 and 1998 is interpreted as indicating a new source high on the SW rift.

The amount of CO (sub 2) , which rises from the depths and subsequently dissolves into shallow groundwater, has been estimated to be more than 4.2X10 (super 9) mol year (super -1) . Most of the gas is released in localised anomalous spots (Lavinio, Solforata, and Ciampino-Albano-Nemi areas), generated by fluid leakage processes from buried pressurized reservoirs hosted by structural highs of the calcareous-siliceous marly basement. The groundwater circulating in the anomalous areas becomes CO (sub 2) oversaturated, generating observable gas manifestations whose composition is mainly controlled by gas-liquid separation processes. A gas flow rate of 6.1X10 (super 8) mol year (super -1) has been measured from the two larger manifestations using the accumulation chamber technique. The presence at shallow level of CO (sub 2) oversaturated groundwater can explain several episodes of sudden release of gas which was documented by historical chronicles from Roman times, until now.

Accumulation-chamber measurements of CO (sub 2) flux are increasingly used to estimate the total magmatic or metamorphic CO (sub 2) released from such areas. To assess the performance of accumulation chamber systems at fluxes one to three orders of magnitude higher than normally encountered in soil respiration studies, a test system was constructed in the laboratory where known fluxes could be maintained through dry sand. Steady-state gas concentration profiles and fractionation effects observed in the 30-cm sand column nearly match those predicted by the Stefan-Maxwell equations, indicating that the test system was functioning successfully as a uniform porous medium. Eight groups of investigators tested their accumulation chamber equipment, all configured with continuous infrared gas analyzers (IRGA), in this system. Over a flux range of approximately 200-12,000 g m (super -2) day (super -1) , 90% of their 203 flux measurements were 0-25% lower than the imposed flux with a mean difference of -12.5%. Although this difference would seem to be within the range of acceptability for many geologic investigations, some potential sources for larger errors were discovered. A steady-state pressure gradient of -20 Pa/m was measured in the sand column at a flux of 11,200 g m (super -2) day (super -1) . The derived permeability (50 darcies) was used in the dusty-gas model (DGM) of transport to quantify various diffusive and viscous flux components. These calculations were used to demonstrate that accumulation chambers, in addition to reducing the underlying diffusive gradient, severely disrupt the steady-state pressure gradient. The resultant diversion of the net gas flow is probably responsible for the systematically low flux measurements. It was also shown that the fractionating effects of a viscous CO (sub 2) efflux against a diffusive influx of air will have a major impact on some important geochemical indicators, such as N (sub 2) /Ar, delta (super 15) N-N (sub 2) , and (super 4) He/ (super 22) Ne.

The selected study area is one of high diffuse CO (sub 2) emission on Mammoth Mountain, CA. Because terrain and source characteristics make this a complex setting for this type of measurement, added consideration was given to source area and upwind fetch. Footprint analysis suggests that the eddy covariance measurements were representative of an upwind elliptical source area (3.8X10 (super 3) m (super 2) ) which can vary with mean wind direction, surface roughness, and atmospheric stability. CO (sub 2) flux averaged 8-16 mg m (super -2) s (super -1) (0.7-1.4 kg m (super -2) day (super -1) ). Eddy covariance measurements of flux were compared with surface chamber measurements made in separate studies [Geophys. Res. Lett. 25 (1998a) 1947; EOS Trans. 79 (1998) F941.] and were found to be similar.

This type of measurement represents a useful and safer method (compared with direct fumarole measurements) for monitoring an active volcano. However, this study shows that not all volcanoes will have a significant diffuse component, even if substantial quantities of gas are released from the crater. The current phase of volcanic activity at Popocatepetl started in December 1994. Since then, frequent ash emissions have been occurring and very large quantities of SO (sub 2) and CO (sub 2) have been measured in the summit plume: up to 60,000 t day (super -1) of SO (sub 2) . From August 1997 until April 1999 over 500 measurements of Rn and CO (sub 2) in soil gas were performed, with extensive coverage of the volcano. Surprisingly, no CO (sub 2) of magmatic origin has been detected. Levels of up to 14% have been measured in some locations, however, with delta (super 13) C values of between -17 per mil and -25 per mil, its origin appears to be biogenic. The average R/R (sub a) value for the He isotopic ratio of samples of soil gas was 0.49 with all samples giving a radiogenic rather than magmatic signature. Some large ravines in the edifice are thought to mark the location of faults. Large displacements have been measured, but only low concentrations of soil gases were recorded. There is no evidence of a geothermal system, which is likely to be connected to the absence of a diffuse gas component.

The surveys were undertaken from 1995 to 1999 to constrain total HLTK CO (sub 2) emissions and to evaluate occasional efflux surveys as a surveillance tool for the tree kills. HLTK effluxes range from 1 to >10,000 g m (super -2) day (super -1) (grams CO (sub 2) per square meter per day); they are not normally distributed. Station efflux rates can vary by 7-35% during the course of the 8- to 16-h surveys. Disturbance of the upper 2 cm of ground surface causes effluxes to almost double. Semivariograms of efflux spatial covariance fit exponential or spherical models; they lack nugget effects. Efflux contour maps and total CO (sub 2) emission rates based on exponential, spherical, and linear kriging models of survey data are nearly identical; similar results are also obtained with triangulation models, suggesting that the kriging models are not seriously distorted by the lack of normal efflux distributions. In addition, model estimates of total CO (sub 2) emission rates are relatively insensitive to the measurement precision of the efflux rates and to the efflux value used to separate magmatic from forest soil sources of CO (sub 2) . Surveys since 1997 indicate that, contrary to earlier speculations, a termination of elevated CO (sub 2) emissions at the HLTK is unlikely anytime soon. The HLTK CO (sub 2) efflux anomaly fluctuated greatly in size and intensity throughout the 1995-1999 surveys but maintained a N-S elongation, presumably reflecting fault control of CO (sub 2) transport from depth. Total CO (sub 2) emission rates also fluctuated greatly, ranging from 46 to 136 t day (super -1) (metric tons CO (sub 2) per day) and averaging 93 t day (super -1) . The large inter-survey variations are caused primarily by external (meteorological) processes operating on time scales of hours to days. The externally caused variations can mask significant changes occurring at depth; a striking example is the masking of a degassing event generated at depth and detected by a soil gas sensor network in September 1997 while an efflux survey was in progress. Thus, occasional efflux surveys are not an altogether effective surveillance tool for the HLTK, and making them effective by greatly increasing their frequency may not be practical.

This paper reports results from accumulation-chamber measurements of soil CO (sub 2) flux from locations in the dead zone and stable isotope and chemical data on fluids from fumaroles, shallow wells, and geothermal production wells within and adjacent to the dead zone. A cumulative probability plot shows three types of flux sites within the dead zone: locations with a normal background CO (sub 2) flux (7 g m (super -2) day (super -1) ); moderate flux sites displaying "excess" geothermal flux; and high flux sites near young vents and fumaroles. A maximum CO (sub 2) flux of 570 g m (super -2) day (super -1) was measured at a location adjacent to a fumarole. Using statistical methods appropriate for lognormally distributed populations of data, estimates of the geothermal flux range from 7.5 t day (super -1) from a 0.14-km (super 2) site near the Stillwater Fault to 0.1 t day (super -1) from a 0.01-km (super 2) location of steaming ground on the valley floor. Anomalous CO (sub 2) flux is positively correlated with shallow temperature anomalies. The anomalous flux associated with the entire dead zone area declined about 35% over a 6-month period. The decline was most notable at a hot zone located on an alluvial fan and in the SG located on the valley floor. Gas geochemistry indicates that older established fumaroles along the Stillwater Fault and a 2-year-old vent in the lower section of the dead zone discharge a mixture of geothermal gases and air or gases from air-saturated meteoric water (ASMW). Stable isotope data indicate that steam from the smaller fumaroles is produced by nearly equal 100 degrees C boiling of these mixed fluids and reservoir fluid. Steam from the Senator fumarole (SF) and from shallow wells penetrating the dead zone are probably derived by 140 degrees C to 160 degrees C boiling of reservoir fluid. Carbon-13 isotope data suggest that the reservoir CO (sub 2) is produced mainly by thermal decarbonation of hydrothermal calcite in veins that cut reservoir rocks. Formation of the dead zone is linked to the reservoir pressure decline caused by continuous reservoir drawdown from 1986 to present. These reservoir changes have restricted flow and induced boiling in a subsurface hydrothermal outflow plume extending from the Stillwater Fault southeast toward the DV floor. We estimate that maximum CO (sub 2) flux in the upflow zone along the Stillwater Fault in 1998 was roughly seven to eight times greater than the pre-production flux in 1986. The eventual decline in CO (sub 2) flux reflects the drying out of the outflow plume.

New data and published results are used to illustrate the effects of various factors on CO (sub 2) emissions from the ground. These factors are: pressure differences between the ambient air and the chamber, wind speed within the chamber, the chamber CO (sub 2) concentration relative to ambient air concentration and the accumulation of water vapor in the chamber. A mathematical analysis of the accumulation of CO (sub 2) in the chamber in terms of diffusion and advection (e.g., air flow out of the ground at geothermal degassing locations) shows that the same protocol should be followed, whether the mechanism of emission is purely by diffusion or by a combination of diffusion and advection. The analysis also yields a simple way for estimating soil CO (sub 2) conductance and the soil CO (sub 2) concentration at the depth of insertion of the chamber into the ground.

We analyzed the annual rings of trees with two main purposes: (1) to track changes in the magnitude of magmatic CO (sub 2) emission over time, and (2) to determine the onset of magmatic CO (sub 2) emission at numerous sites on Mammoth Mountain. The onset of CO (sub 2) emission at different areas of tree kill was determined to be in 1990, closely following the seismic events of 1989. At Horseshoe Lake (HSL), CO (sub 2) emission was found to have peaked in 1991 and to have subsequently declined by a factor of two through 1998. The tree-ring data also show that emissions of magmatic carbon from cold springs below the tree-kill areas occurred well before 1989. Trees located on the margins of the kill areas or otherwise away from zones of maximum gas discharge were found to be better integrators of magmatic CO (sub 2) emission than those located in the center of tree kills. Although quantitative extrapolations from our data to a flux history will require that a relationship be established between (super 14) C depletion in tree rings and average annual magmatic CO (sub 2) flux, the pattern of (super 14) C depletion in tree rings is likely to be the most reliable indicator of the long-term changes in the magnitude of CO (sub 2) release from Mammoth Mountain.

The method is done by releasing the tracer gas into the vent at known flux and by measuring CO (sub 2) to the tracer gas ratio in situ. In Izu-Oshima, we carried out flux measurements at a low-temperature steam well (90 degrees C) with three different tracer gas species (H (sub 2) , CH (sub 4) and SF (sub 6) ) and three methods (GC, portable analyzers, FTIR) to evaluate this method. The calculated CO (sub 2) flux showed an average of 2.3 t/day. In the case of Kirishima volcanic area, the flux measurement was tested at two low-temperature fumaroles on Iwoyama cone (<100 degrees C). The CO (sub 2) fluxes were 9X10 (super -2) and 2X10 (super 0) kg/day, respectively. The total CO (sub 2) flux from the cone including both fumarolic and ground CO (sub 2) discharges was estimated to be less than several tons per day. In Teide volcano, CO (sub 2) flux measurements were performed in the fumarolic system of the summit crater (85 degrees C). CO (sub 2) flux from one fumarole reached levels up to 30.2 kg/day. We estimated that the CO (sub 2) discharge from all fumaroles is roughly 30 t/day or less at maximum. These results imply that the total output of CO (sub 2) flux from Teide's fumarolic activity is much lower than the observed levels of CO (sub 2) diffuse degassing from the summit crater.

SO (sub 2) emission rates were measured 16 times by correlation spectrometer (COSPEC) from 1986 to 1999 and range from 171 to 900 Mg day (super -1) . We estimate the average SO (sub 2) emission rate was 430+ or -70 Mg day (super -1) between 1983 and 1999. CO (sub 2) emission rates of 2570 and 2650 Mg day (super -1) were determined in January 1998 by aircraft directly in the plume using a CO (sub 2) analyzer and a ladder survey technique. Using the average SO (sub 2) emission rate and a CO (sub 2) /S weight ratio of 3.6 previously reported for fumarole samples collected from the crater floor, an indirect estimate of the CO (sub 2) is 1550 Mg day (super -1) . A soil gas survey of CO (sub 2) emissions from the crater floor gave an emission rate of 8.7 Mg day (super -1) . Soil gases contribute less than 1% of the total CO (sub 2) emitted from this volcano and show that the magmatic degassing of the underlying andesite magma is mostly isolated to the active crater and associated fumaroles. Volatile elements (H (sub 2) O, Cl, F, S) were measured in melt inclusions trapped in plagioclase and clinopyroxene crystals. The low H (sub 2) O contents (0.6+ or -0.2 wt.%) of melt inclusions suggest that crystal formation occurs at pressures of 35 to 70 bars. The Cl contents of melt inclusions (0.10-0.18 wt.%) are higher than that of matrix glass (0.11 wt.%), suggesting Cl was lost from the magma between the time of crystallization and eruption. Therefore, Cl degassing also occurred in part at shallow depths in the magmatic system. The low SO (sub 2) contents of both melt inclusions and matrix glass implies that it exsolves at depths greater than 300 m. CO (sub 2) is insoluble in andesitic magma and probably was degassing with SO (sub 2) at depths >300 m within the magmatic system.

CO (sub 2) flux values for May and September surveys ranged from 0.1 to 18,150 g m (super -2) day (super -1) and from 0.1 to 9685 g m (super -2) day (super -1) , respectively. Statistical graphical analysis showed three overlapping populations. The spatial distribution of these emissions correlated quite closely with the geothermal and geological characteristics of the studied area. The structure releasing higher CO (sub 2) is the summit cone Oyama and surrounding areas, where the most obvious geothermal features occur. A total output about 100-150 t day (super -1) is estimated from this area. A good correlation was observed between soil CO (sub 2) flux and soil temperature at the summit caldera indicating extensive condensation of fumarolic steam within the upper part of Miyakejima. Carbon isotopic analysis of selected samples inside the summit caldera (delta (super 13) C-CO (sub 2) = -0.90 per mil to -5.70 per mil) suggests a mixing of carbon derived from marine limestone and magmatic CO (sub 2) while a clear biogenic origin (delta (super 13) C-CO (sub 2) = -14.76 per mil to -25.52 per mil) is observed for the diffuse degassing of CO (sub 2) outside summit caldera.

Volcano behavior was relatively quiet and SO (sub 2) flux averaged 1670+ or -1420 t/day (51 measurements), relatively small for Popocatepetl. Concurrent HCl/SO (sub 2) and HF/SO (sub 2) ratios were 0.17+ or -0.01 and 0.031+ or -0.003, respectively, about the same as ratios measured from 1994 to 1997. The amount of CO (sub 2) in the volcanic plume was quantified using FASCODE in which atmospheric CO (sub 2) is numerically subtracted from the total infrared spectrum to obtain the residual magmatic CO (sub 2) . Surprisingly, CO (sub 2) /SO (sub 2) mass ratios rose dramatically to values as high as 140, about 30 times higher than typical values of 2 to 8 measured from 1994 to 1996. These excursions in high CO (sub 2) /SO (sub 2) ratios were short-lived, lasting no longer than about 0.5 to 3.0 h but CO (sub 2) flux occasionally exceeded 100,000 t/day. We estimate that the average CO (sub 2) /SO (sub 2) ratio for the period was about 23, yielding an average CO (sub 2) flux of roughly 38,000 t/day. Chemical and petrographic analyses of lava and pumice erupted during explosions on June 30, 1997 and January 1, 1998 show conclusively that Popocatepetl produces mixed products formed by injection of mafic magma into a more silicic chamber at temperatures and pressures of roughly 1040 degrees C and 5 kbar. In addition, Popocatepetl eruptive products include xenoliths of metamorphosed carbonate rocks containing wollastonite and other calc-silicate minerals indicating reaction of magma with Cretaceous limestone underlying the volcano. Using a normal CO (sub 2) /SO (sub 2) ratio of 4 for reference, we calculate an average excess CO (sub 2) production of 32,000 t/day for 17 days. This would require assimilation of only 5X10 (super -4) km (super 3) of limestone, an amount easily accessible in the 3-km-thick Cretaceous section beneath the volcano. We also examine two scenarios in which excess CO (sub 2) is produced by degassing of subjacent basalt magma, but these explanations seem less plausible to us. Because many other volcanoes are underlain by carbonate sequences, short-duration bursts of CO (sub 2) flux, and increased CO (sub 2) /SO (sub 2) ratio, might be observed at other sites, if simultaneous, real-time measurements of major gas species are made.

The sampling system consisted of a collection borehole and a sampling assembly designed specifically for the easy removal and replacement of a filter paper pad used to collect solution samples at locations throughout the borehole. Simulations were conducted to approximate an experimental setup at Busted Butte, Nevada, for two hypothetical soil formations: a Calico Hills tuff and a loamy sand. The purpose of the simulations was to evaluate any significant effects the sampling system might have on the prevailing flow and transport processes. The simulation results revealed that the overall disturbance of the system is a superposition of three major components caused by the installation and operation of the sampling device. Two of these components delayed the observed solute breakthroughs and hence increased the mean and variance of solute travel times, whereas the third disturbed the system by increasing the mean solute velocity. The analytical solution of the one-dimensional convective-dispersive equation in the fluid coordinate frame was introduced to approximate the system response at different levels of disturbance for a better understanding of the system dynamics. The general difficulties in interpreting flow and transport properties using field-measured data are illustrated. To better interpret field data, it is important to understand the limitations a measuring device may impose on data analysis.

AN - 70942436; 11418130 AB - The site-specific recombination system of bacteriophage P1 is composed of the Cre recombinase that recognizes a 34-bp loxP site. The Cre/loxP system has been extensively used to manipulate eukaryotic genomes for functional genomic investigations. The creation of additional heterologous loxP sequences potentially expands the utility of this system, but only if these loxP sequences do not recombine with one another. We have developed a stringent in vivo assay to examine the degree of recombination between all combinations of each previously published heterologous loxP sequence. As expected, homologous loxP sequences efficiently underwent Cre-mediated recombination. However, many of the heterologous loxP pairs were able to support recombination with rates varying from 5 to 100%. Some of these loxP sequences have previously been reported to be non-compatible with one another. Our study also confirmed other heterologous loxP pairs that had previously been shown to be non-compatible, as well as defined additional combinations that could be used in designing new recombination vectors.

Previous approaches to modeling the distribution of low-energy neutrons beneath the surface of the earth have derived the thermal neutrons directly from the high-energy neutron flux. We have improved on this model by deriving the thermal neutrons from the moderation of the epithermal neutron flux, and the epithermal neutrons from the fast neutron flux. Predictions from the improved model agree well with experimental measurements of thermal and epithermal neutron fluxes both above and below the land/atmosphere interface. Recalibration of the (super 36) Cl surface production parameters of Phillips et al. [Phillips, F. M., Zreda, M. G., Flinsch, M. R., Elmore, D., Sharma, P., 1996. A reevaluation of cosmogenic (super 36) Cl production rates in terrestrial rocks. Geophys. Res. Lett., 23, pp. 949-952), incorporating the new approach to simulating the low-energy neutron fluxes, yielded the following values: P (sub s,Ca) 66.8 atoms (g Ca) (super -1) year (super -1) , P (sub s,K) 137 atoms (g K) (super -1) year (super -1) , and P (sub f) (0) 626 neutrons (g air) (super -1) year (super -1) (this updated calibration also includes mugenic (super 36) Cl production, based on independent work). Comparison of ages of three groups of samples from sites not included in the calibration data set with independently determined ages gave an average absolute error of 6.6% for all three data sets and coefficients of variation among the samples in the groups ranging from 5% to 14%.

Low rainfall (approximately 170 mm/yr) and a thick unsaturated zone (500-1000 m) are important physical attributes of the site because the quantity of water likely to reach the waste and the paths and rates of movement of the water to the saturated zone under future climates would be major factors in controlling the concentrations and times of arrival of radionuclides at the surrounding accessible environment. The framework for understanding the hydrologic processes that occur at this site and that control how quickly water will penetrate through the unsaturated zone to the water table has evolved during the past 15 yr. Early conceptual models assumed that very small volumes of water infiltrated into the bedrock (0.5-4.5 mm/yr, or 2-3 percent of rainfall), that much of the infiltrated water flowed laterally within the upper nonwelded units because of capillary barrier effects, and that the remaining water flowed down faults with a small amount flowing through the matrix of the lower welded, fractured rocks. It was believed that the matrix had to be saturated for fractures to flow. However, accumulating evidence indicated that infiltration rates were higher than initially estimated, such as infiltration modeling based on neutron borehole data, bomb-pulse isotopes deep in the mountain, perched water analyses and thermal analyses. Mechanisms supporting lateral diversion did not apply at these higher fluxes, and the flux calculated in the lower welded unit exceeded the conductivity of the matrix, implying vertical flow of water in the high permeability fractures of the potential repository host rock, and disequilibrium between matrix and fracture water potentials. The development of numerical modeling methods and parameter values evolved concurrently with the conceptual model in order to account for the observed field data, particularly fracture flow deep in the unsaturated zone. This paper presents the history of the evolution of conceptual models of hydrology and numerical models of unsaturated zone flow at Yucca Mountain, Nevada (Flint, A. L., Flint, L. E., Kwicklis, E.

The main impediment to the realistic treatment of anelastic attenuation in 3D is the very large computational storage requirement imposed by the additional variables. We previously proposed an alternative to the conventional memory-variable formulation, the method of coarse-grain memory variables, and demonstrated its effectiveness in acoustic problems. We generalize this memory-efficient formulation to 3D anelasticity and describe a fourth-order, staggered-grid finite-difference implementation. The anelastic coarse-grain method applied to plane wave propagation successfully simulates frequency-independent Q (sub p) and Q (sub s) . Apparent Q values are constant to within 4% tolerance over approximately two decades in frequency and biased less than 4% from specified target values. This performance is comparable to that achieved previously for acoustic-wave propagation, and accuracy could be further improved by optimizing the memory-variable relaxation times and weights. For a given assignment of relaxation times and weights, the coarse-grain method provides an eight-fold reduction in the storage requirement for memory variables, relative to the conventional approach. The method closely approximates the wavenumber-integration solution for the response of an anelastic half-space to a shallow dislocation source, accurately calculating all phases including the surface-diffracted SP phase and the Rayleigh wave. The half-space test demonstrates that the wave field-averaging concept underlying the coarse-grain method is effective near boundaries and in the presence of evanescent waves. We anticipate that this method will also be applicable to unstructured grid methods, such as the finite-element method and the spectral-element method, although additional numerical testing will be required to establish accuracy in the presence of grid irregularity. The method is not effective at wavelengths equal to and shorter than 4 grid cell dimensions, where it produces anomalous scattering effects. This limitation could be significant for very high-order numerical schemes under some circumstances (i.e., whenever wave-lengths as short as 4 grids are otherwise within the usable bandwidth of the scheme), but it is of no practical importance in our fourth-order finite-difference implementation.

The skarn records early low f (sub O2) conditions similar to those of reduced W and Au skarns. Initial skarn-forming conditions were: P (sub L) < or =221 bar (22.1 MPa), X (sub CO2) < or =0.10, T = 450-400 degrees C, log f (sub O2) nearly equal -30, and log f (sub S2) < or =-13. Late skarn records combined effects of T, f (sub O2) , f (sub S2) , X (sub CO2) , and appearance of an immiscible CO (sub 2) -rich vapour. The absence of a contact aureole indicates that skarn reactions were driven by advective heat transfer from an infiltrating fluid. Elsewhere in the region, hypersaline, synvolcanic fluids produced oxidized endoskarn in rhyolite. Development of carbonate-hosted, reduced skarn in caldera moat sediments is attributed to: (1) the nature of the host rock and reaction along a lengthy flow path; (2) early, but temporary, dilution of brine influx by CO (sub 2) -producing reactions; and (3) cooling, possibly accompanied by increased brine influx with time.

The main goals of our DOE/NETL project are to better understand, predict and monitor the migration and ultimate fate of injected CO2 in an oil reservoir through a field demonstration experiment at a site in southeastern New Mexico. Advanced modeling and flow simulation techniques were used to develop a geologic model of the site and to verify the feasibility of CO2 injection into that reservoir. The results of these simulations will be used to decide on wellhead injection conditions, to guide selection of geophysical survey parameters and to bound test conditions for lab experiments using core samples. A suite of modern geophysical characterization techniques will be used to monitor the advancing CO2 plume both during and after injection. The field data will provide a unique opportunity to test, refine and calibrate the computer model(s) that simulate those subsurface interactions. The laboratory experiments will measure changes in reservoir formation properties and chemical reactions with CO2 flooding. Iteration of modeling, laboratory and field data will improve simulation tools and provide higher quality input data for those models. Ultimately, these results will be used to predict storage capacity and physical and chemical changes in reservoir properties, such as fluid composition, porosity, permeability, and phase relations. Science or technology gaps related to engineering aspects of CO2 sequestration would be identified in the course of this study.

A simple elastic solid should show a monotonic increase in the elastic constants as temperature decreases. The basalt samples show this gross behavior while the sandstone shows a very unexpected anomalous regime between 40 K and 200 K where the elastic constants decrease with decreasing temperature. Both rocks show temperature-dependent structure in both the modulus and internal friction, and also significant hysteresis, indicating history and rate-dependent properties. This data provides insight into the time and energy scales of dynamical effects observed in sandstones. The low temperature range (4K-300K) is of interest due to the renewed interest in Mars and Lunar rocks. Copyright 2001 by the American Geophysical Union.

Eight workers were in the workroom during the release and four of the worker's exposures were enough to warrant multiple chelation treatments. Post accident analyses of the dispersion rates and patterns of the released aerosol were performed to: 1) identify the release location, 2) analyze the dynamics of the worker exposures, and 3) evaluate the response of the continuous air monitors (CAMs) in the room. These analyses were based on previous temporally and spatially resolved airflow and tracer aerosol studies and from results from retrospective air samples collected in the room during the release. Results suggest that the highest aerosol concentrations were closest to the release location and the concentrations decreased with distance and time. Also, we estimate that the aerosol cloud took anywhere from 1 to 5 min to reach the nearest CAM, which when it alarmed, prompted the workers to exit the room ending further exposure. Therefore, the workers closest to the release received the largest exposures, and most of their exposure, occurred in the first few minutes. Finally, results from this release combined with previous studies suggest that a more optimal CAM placement configuration could have reduced doses to the workers. Numerous actions are being taken to upgrade the CAM system at the LANL Plutonium Facility.

The first is a threshold-based method for obtaining gene groups, and the second is a method for obtaining a measure of confidence in SVD analysis. Gene groups are obtained by identifying elements of the left singular vectors, or gene coefficient vectors, that are greater in magnitude than the threshold W N super(- one half ), where N is the number of genes, and W is a weight factor whose default value is 3. The groups are non-exclusive and may contain genes of opposite (i.e. inversely correlated) regulatory response. The confidence measure is obtained by systematically deleting assays from the data set, interpolating the SVD of the reduced data set to reconstruct the missing assay, and calculating the Pearson correlation between the reconstructed assay and the original data. This confidence measure is applicable when each experimental assay corresponds to a value of parameter that can be interpolated, such as time, dose or concentration. Algorithms for the grouping method and the confidence measure are available in a software application called SVD Microarray ANalysis (SVDMAN). In addition to calculating the SVD for generic analysis, SVDMAN provides a new means for using microarray data to develop hypotheses for gene associations and provides a measure of confidence in the hypotheses, thus extending current SVD research in the area of global gene expression analysis.

This requires efficient methods to create diversity coupled with methods to select polypeptides with desired properties. In this review we describe the use of in vivo recombination as a powerful way to generate diversity. The novel principles for the recombination process and several applications of this process for the creation of phage antibody libraries are described. The advantage and disadvantages are discussed and possible future exploitation presented.

Because the details about how the data was examined can greatly impact the conclusions, the epidemiologist then wants to know more information, such as 'over what time period' and 'how many other cancer types were examined'. For example, city A might have calculated cancer rates for many age groups within different regions of the city over many time intervals, but reported only the highest cancer rate discovered in a particular group. We will refer to such selective reporting as 'maximally selecting measures of evidence of disease clustering', or less formally as 'fishing for statistical significance'. The objective of this paper is to study the behaviour of maximally selected statistics for measuring the extent of clustering in disease outbreaks. The original data is the time and location of each reported case of the disease. In some cases we are only given aggregates of the original data, such as the number of cases during a time period over a given region. We introduce new and review existing methods for correcting for the effect of making maximal selections in disease cluster detection. We consider three main cases with examples. We demonstrate via simulation and analytical approximations that some types of 'fishing' are simple to correct for while others are not.

These SIRs and shocks produced a substantial heliospheric processing of the solar wind. Only a subset of the SIRs recurred on successive solar rotations and only about half of the well-defined SIRs observed poleward of S9.8 were bounded by forward-reverse shock pairs. The majority of the SIRs had local magnetic topologies and azimuthal orientations similar to, but meridional tilts different from, those observed in the first polar orbit when most SIRs corotated with the Sun. The irregular meridional tilts presumably were a consequence of a complex coronal geometry and the temporally evolving nature of the solar wind flow at this time. A lack of reverse shocks poleward of S54 (with one exception) and a lack of well defined SIRs poleward of S65 is evidence that SIRs develop more slowly with distance at high latitudes.

Two types of tufa are represented, informally defined as (1) an easily disaggregated, fine-grained mixture of calcite and quartz (friable tufa) in the southwest Tecopa Valley, and (2) hard, vuggy micrite, laminated carbonate, and carbonate-cemented sands and gravels (indurated tufa) along the eastern margin of Lake Tecopa. High delta (super 18) O (sub VSMOW) (Vienna standard mean ocean water) water values, field relations, and the texture of friable tufa suggest rapid nucleation of calcite as subaqueous, fault- controlled groundwater discharge mixed with high-pH, hypersaline lake water. Variations between delta (super 18) O (sub VSMOW) and delta (super 13) C (sub PDB) (Peedee belemnite) values relative to other closed basin lakes such as the Great Salt Lake and Lake Lahontan suggest similarities in climatic and hydrologic settings. Indurated tufa, also fault controlled, formed mounds and associated feeder systems as well as stratabound carbonate-cemented ledges. Both deposits represent discharge of deeply circulated, high total dissolved solids, and high pCO (sub 2) regional groundwater with kinetic enrichments of as much as several per mil for delta (super 18) O (sub VSMOW) values. Field relations show that indurated tufa represents episodic discharge, and U-series ages imply that discharge was correlated with cold, wet climate episodes. In response to both the breaching of the Tecopa basin and a modern arid climate, most discharge has changed from fault-controlled locations near basin margins to topographic lows of the Amargosa River drainage at elevations 30-130 m lower. Because of episodic climate change, spring flows may have relocated from basin margin to basin center multiple times.

The LAHET code system, a purely physical model for calculating cosmic-ray particle fluxes, was used to simulate cosmic-ray particle interactions with extraterrestrial matter. We discuss the depth and size dependence of the shielding parameter (super 22) Ne/ (super 21) Ne, which is used for reconstruction of pre-atmospheric sizes, depth, and exposure histories. The (super 22) Ne/ (super 21) Ne ratio decreases with increasing depth or pre-atmospheric size but then increases with depth in very large objects. This increase with depth in the (super 22) Ne/ (super 21) Ne ratio means that this ratio is a poor indicator of shielding in some large objects. The dependence of (super 3) He/ (super 21) Ne as function of (super 22) Ne/ (super 21) Ne was also calculated, and differences between the calculations and the Bern line are discussed.

It is based on the premise of Assouline et al. [1998] that soil structures evolve from a uniform random fragmentation process. This assumption allows us to derive hydraulic properties of soils (water retention curves and unsaturated hydraulic conductivity) from primary properties, such as pore geometry and soil structure. We tested our RHC expression against different soil types and found that it fits data better than the widely used models of Brooks and Corey [1964] and van Genuchten [198O].

AN - 76990493; 11262166 AB - A method based on two-tiered fluorescence resonant energy transfer (FRET) has been developed for selective and sensitive detection of species involved in a multivalent interaction. Pentavalent binding between cholera toxin and ganglioside GM1 is used as a model system to demonstrate the advantage of the two-tiered FRET over one-stage FRET in both conventional fluorimeter and flow cytometer. In the system, three fluorescent probes (namely, fluorescence donor, acceptor, and intermediate) are covalently tagged to receptors, and the intermediate is used to bridge the energy transfer between the donor and acceptor even though the donor's fluorescence spectrum does not overlap with absorption spectrum of the acceptor. One of the most significant improvements of the scheme over one-stage FRET is a dramatic decrease in the background fluorescence of the acceptor fluorescence, which, theoretically and practically, increases the detection sensitivity.

The fire left a large amount of residual ash in burned areas. Sampling of ash and muck (post-fire sediments dominated by reworked ash) was conducted in locations representative of background conditions west (upstream) of the Laboratory. Ash and muck samples were also collected in the Viveash fire area (near Pecos, NM) for comparison. These data document the presence of elevated plutonium-239, 240, cesium-137, and strontium-90 concentrations associated with global fallout from above-ground nuclear testing conducted primarily in the 1950s and 1960s. An increase in the concentrations of several naturally occurring metals (e.g., barium, manganese, and calcium) readily taken up into plant tissue is also observed. Radionuclide and metal concentrations increased by up to an order of magnitude in ash. The average concentration of cesium-137 in ash is 4.4 pCi/g, about 20 times the pre-fire background concentration. Flood deposits sampled kilometers from the mountain-front source of ash show persistent elevated concentrations of the radionuclide and inorganic constituents, including in watersheds unaffected by Laboratory operations. The data from the ash and muck samples are important for interpreting concentrations of radionuclides present in stormwater and sediment deposits, and are necessary for distinguishing fire-related constituents in stormwater and sediments from legacy contamination in canyons on the Laboratory. The ash and muck data provide a necessary post-fire baseline to support the assessment of potential impacts to the Laboratory and offsite (e.g., the Rio Grande and Cochiti Reservoir) from fire-related contaminants found in storm runoff. Much of the "contamination" transported to the Rio Grande may be unrelated to the Laboratory. Risk assessors should not, however, discriminate between sources of contamination in their assessments because the potential effects of exposure to radionuclides and metals are irrespective of their source. Knowledge of the source of contamination primarily guides the nature and location of potential mitigation measures.

An intensely burned soil area in the Santa Fe National Forest west of Los Alamos, New Mexico, was selected and divided into 6 plots (1 m by 7 m). The surfactant (Magic Wet (super TM) , Cognis Corp.), was applied to three plots at three different application rates (16, 33, and 82 ml/m (super 2) ). A soil fixative (Terra-Control (super TM) , Cognis, 170 ml/m (super 2) ) plus the surfactant (16 ml/m (super 2) ) was applied to a fourth plot, a fifth plot was raked with no other treatment, and a sixth plot was an untreated control. For two months following the applications, soil hydrophobicity was measured using a water-drop test, and erosion was monitored visually. Both the surfactant and fixative are non-toxic, biodegradable over a multi-month time period, and used in agricultural (vegetable crop) and golf-course applications. The shallow soil profile consisted of a black, burned soil from 0-2 cm, a light tan mineral soil from 2-3.5 cm, and a medium tan mineral soil below 3.5 cm across all plots. Results of the water drop tests showed that the uppermost, black soil layer tended to be very hydrophilic (instant drop adsorption) throughout the study. The light tan soil layer was consistently hydrophobic (drop adsorption greater than 30 minutes) in all plots before surfactant application.The lowest, medium tan layer, below 3.5 cm, tended to be hydrophilic in most cases. Surfactant application reduced hydrophobicity in the tan soil layer in some locations, and roughly correlated with amount of surfactant applied. The effect was uneven, even after rainfall. The soil fixative application was very effective in preventing erosion throughout subsequent heavy rain events. Reduction of hydrophobicity below the fixative layer was also uneven in the tan soil. Oak seedling germination was greatest in the fixative-treated plot. Additional hydrophobicity tests will be performed after this spring's snowmelt.

Field-scale tracer tests at Busted Butte are being carried out in order to validate conceptual and numerical models of unsaturated-zone transport for the Yucca Mountain Project. The underground facility consists of a 10 m by 10 m by 7 m undisturbed test block instrumented with horizontal injection and collection boreholes. A tracer solution containing reactive and non-reactive tracers was introduced into the injection boreholes. After the tracers traveled through the rock, they were collected using an inverting membrane system. Pads consisting of bundles of three filter paper strips, 4 cm by 28.5 cm, were attached to inflatable membranes. The membranes were emplaced by inversion into collection boreholes and inflated, which pushed the pads against the walls of the borehole. The pads were left in place for 1-2 weeks to imbibe porewater, then removed and taken back to the laboratory where the tracer solution was extracted and analyzed to determine the concentration of the various tracer constituents. After 20 months of tracer injection, three boreholes were drilled into the tracer plume to collect rock samples for tracer analyses. The holes were then instrumented with inverting membrane collection systems. By extracting tracer from the pads and from the rock we can determine the accuracy with which porewater extracted from the pads reflects the chemistry of the porewater in the rock. This work will enable us to assess the effectiveness of the inverting membrane system of pore water sampling, and thus validate it as a method of collecting porewaters from the unsaturated zone.

The stable isotopic ratios of most Lechuguilla pools (delta D-value of -50 to -60 %, delta (super 18) O-value of -7 to -8%) fell in a smaller range and were isotopically lighter than those of Carlsbad cavern pools (delta D-value of -22% to -47%, delta (super 18) O-value of -3.6 to -6.8%), indicating that pools in Lechuguilla experience less evaporation than pools in Carlsbad Cavern. The weighted average isotopic composition of local precipitation (delta D-value of -52%, delta (super 18) O-value of -7.0%) and the stable isotopic composition of a nearby spring (delta D-value of -53%, delta (super 18) O-value of -7.6%) fall in the range of values of Lechuguilla pools. This suggests that waters in Lechuguilla have undergone little change during storage within the cave and therefore accurately represent the isotopic composition of local ground seepage water. Stable isotopic values for Lechuguilla pools exhibit a trend linking the isotopic composition with depth. Pools within 200 meters of the surface were slightly lighter isotopically than pools at greater depths. There is no chemical evidence that this trend represents greater evaporation rates at greater depths. It may represent a change in the long-term average isotopic composition of the regional precipitation, changing this trend with depth to a trend with age. This suggests that younger waters have a slightly lighter isotopic composition than older waters. Some chlorine-36 data supports this hypothesis, however, there is one inconsistency. More samples will be collected in the near future in order to further test this hypothesis.

Burn severity was high or moderate over 42% of the burned area, focused in the upper watersheds of the Pajarito Plateau. The presence of hydrophobic soils and nearly complete combustion of vegetation has altered the hydrologic characteristics and the water quality within these watersheds. LANL, located in the middle of the Pajarito Plateau, maintains a network of 53 gaging stations, equipped with ultrasonic transducers that trip automated samplers to collect water samples from every flow event. The pre-fire data set represents stormwater runoff quality from 1990-1999, for metals and general inorganics from all the stations. These data were averaged to establish a LANL-wide pre-fire 10-year average. After the fire, samples of stormwater runoff were collected on 30 days between June 2 and October 30. The results for each analyte were averaged to develop a post-fire LANL-wide average. Both pre- and post- fire averages are for dissolved constituents only. Post-fire the concentration of most of the metals (Ag, B, Be, Cd, Co, Cr, Cu, Hg, Mo, Ni, Pb, Sb, Sn, Tl, V, Zn) and one nutrient (P) in runoff decreased, by factors of between 2 and 45. The decrease is probably due to dilution by the larger volume of runoff. The concentration of three metals (Mn, Sr, and U) and five inorganics (Ca, K, Mg, Na, and SO (sub 4) ) increased in the runoff after the fire. The concentration of metals and sulfate increased on the order of 2 to 10 times, while the concentration of Ca, K, Mg, and Na increased by factors of 280 to 4500. This increase, despite the increased volume of runoff, indicates that these were constituents of the ash incorporated in the stormwater. The concentration of five metals (As, Ba, Fe, Se, and Ti) were apparently unaffected by the fire.

New seismic, gravity, and magnetotelluric data acquired by the Summer of Applied Geophysical Experience (SAGE) program of the Los Alamos National Laboratory have been combined with Mobil (originally Transocean) seismic reflection profiles acquired in 1976-1978 to define the complex stratigraphy and structure of the basin. The Mobile data set consists of numerous parallel and intersecting lines which together provide a robust 3-D image of the basin. Several deep wells allow correlations between reflectors and lithology. Precambrian basement is imaged beneath the entire basin. Pennsylvanian limestone/mudstone, Permian and Triassic redbeds, and younger continental units occur throughout much of the basin. An Eocene redbed unit overlying a post-Laramide unconformity truncates lower units to the east and south. From these data we infer the following: (1) The southern Espanola basin is a shallow asymmetrical synclinal basin comprising a ramp dipping westward from the Sangre de Cristo uplift and an east-dipping monoclinal flexure (Cerrillos uplift) adjacent to the La Bajada fault.(2) A thick (2380 m) section of Paleozoic and Mesozoic sedimentary rocks beneath the western limb of the basin is truncated northeastward by a post-Laramide (Eocene) erosional surface, reflecting a Laramide uplift broader than the present Sangre de Cristo range. (3) No evidence exists for a major north-trending fault parallel to the basin axis, nor for a northeast-trending fault parallel to the Santa Fe River. (4) Precambrian rocks and electrically-resistive basement are up to 4 km below the surface in the eastern Santa Domingo basin. We relate the Cerrillos uplift to flexural uplift adjacent to the La Bajada fault, which was active until less than 3 Ma. The La Bajada fault serves as a relay fault, transferring extension between the Albuquerque and Espanola basins.

Barium, Ca, CO (sub 3) , Fe, Mg, Mn, K, Na, SiO (sub 2) , Sr, U, and other trace elements are concentrated in ponderosa ash, producing a pH of 9.3 when leached with deionized water. Calcite formed within the ash from the oxidation of organic carbon according to an overall reaction: CaC (sub 2) O (sub 4) + 0.5O (sub 2) (g) = CaCO (sub 3) + CO (sub 2) (g). Reduction of metals occurs as a result of the high temperature of the fire (> 680 degrees C) and combustion of organic carbon. These reactions influence the solubility of Mn(II, IV) solids, for example (Ca, Mn (super 2+) )Mn (sub 4) (super 4+) O (sub 9) 3H (sub 2) O observed in fracture fills within the Bandelier Tuff. Elevated concentrations of dissolved Mn(II) have been observed in surface water and alluvial groundwater. Prior to the fire, native waters were characterized by a Ca (super 2+) -Na (super +) -HCO (sub 3) (super -) composition with TDS < 120 mg/L. Since the fire, storm waters are characterized by a Ca (super 2+) -K (super +) -HCO (sub 3) (super -) -SO (sub 4) (super 2-) composition with TDS ranging from 450-1,000 mg/L. Increased concentrations of HCO (sub 3) (super -) enhance complexation of U(VI) species as UO (sub 2) (CO (sub 3) ) (sub 2) (super 2-) and UO (sub 2) (CO (sub 3) ) (sub 4) (super 4-) . Since the fire, surface water is predicted to be at equilibrium with BaSO (sub 4) , oversaturated with CaCO (sub 3) and SrCO (sub 3) , and undersaturated with (UO (sub 2) )SiO (sub 4) 2H (sub 2) O. MINTEQA2 was used to quantify adsorption of solutes onto hydrous ferric oxide (HFO) occurring in creek channels and alluvial groundwater. The diffuse layer model (DLM) was selected to quantify adsorption of Sr (super 2+) and UO (sub 2) (super 2+) onto HFO. Based on the simulations, Ca (super 2+) strongly competes with Sr (super 2+) and UO (super 2) (sub 2+) for adsorption sites. This competition increases with increasing pH, which may account for increased concentrations of dissolved solutes.

Field site fault density is much less than 1:10 m and in situ moisture content data show matric potential lies between -300 and -600 cm. These results suggest small-displacement faults can move significant amounts of recharge through sandy parts of arid vadose zones given sufficient fault densities.

Tracers used in batch tests include the reactive tracer ion lithium, and the non-reactive tracer ions bromide, molybdate, and radioactive pertechnetate (Tc (super 99) O (sub 4) (super -) ). Two intervals from 19P were tested, 410-415 and 420-425 feet below ground surface (bgs), for comparison with well 19D1 intervals. Five intervals from 19D, distributed throughout the unconsolidated alluvium portion of the well, were batch tested (405-410, 420-425, 500-505, 580-585, and 660-665 ft bgs). Lithium K (sub D) values for finer fractions (200 mesh and finer) of 19P and 19D were greater than for coarser fractions; overall K (sub D) values for 19P were similar to values for 19D. Column studies tested the material from the upper portion of 19D, from 405-410 and 420-425 ft bgs. Lithium, bromide, and pentafluorobenzoicacid (PFBA) were used as reactive and non-reactive tracers, respectively. Two or more flow rates were tested for each of two or more tracer concentrations. Typically, lithium breakthrough was observed between 4 and 8 pore volumes. Major cations (Na (super +) , Ca (super 2+) , Mg (super 2+) , and K (super +) ) exiting the columns were analyzed for input into a reactive tracer transport model. Column and batch isotherm test results were modeled to obtain best parameter estimations from breakthrough curves, and to calculate equilibrium coefficients and incorporate cation exchange capacity data into the analysis. Inclusion of the major cation concentrations along with lithium in the reactive exchange model was found to improve model fit significantly. Replication of results between duplicate columns was excellent. Column and batch interpretations ultimately will be compared with field tracer test results to determine the effectiveness of laboratory tests in predicting operational results in the field.

Springs, surface waters, and alluvial groundwater in CdV have been monitored for a wide-range of hydrogeochemical parameters since 1997, because of the environmental contamination (Ba and high explosives) present in the upper reaches of the canyon. Three springs and five alluvial wells in CdV have: (1) been instrumented for continuous monitoring of T, water level, and specific conductance; (2) been hand sampled weekly for T, pH and water level; and (3) been sampled at least quarterly for a wide suite of chemical constituents including cations, anions, HE, and stable isotopes. In addition, over ten other locations in the CdV hydrologic system, including surface water stations, have been periodically sampled for subsets of these constituents. Although some of these sampling protocols were interrupted by the CGF, the data available for the system from both before and after the CGF enable a detailed empirical investigation of the effects of the CGF on the hydrogeochemistry of a burned canyon system. Little effect was observed on any of the physical parameters of the system (alluvial well water elevations, spring flow rates, water temperature) following post-CGF monsoonal storms. One moderate-sized surface water flood event was observed. This suggests that the physical hydrology of the CDV subsurface system was not strongly impacted by the CGF, although the small magnitude of the monsoonal rains during 2000 make this conclusion subject to further study in 2001. Alluvial wells show a slight increase in specific conductance post-CGF, suggesting an increase in ionic strength in waters within the alluvial system, whereas pH shows no systematic changes due to effects of the CGF. Chemical data from surface waters, alluvial wells and springs will also be presented.

Detection of elevated levels of radioisotopes associated with global nuclear fallout indicates presence in the pool of significant nuclear-era (post-1950) water, and enables estimates of minimum infiltration velocities. Lechuguilla Cave (Carlsbad Caverns National Park, New Mexico) is the deepest limestone cave in the United States. Sixteen samples from the Entrance Series, the Western Borehole and the Near East regions of the cave have been analyzed for chlorine-36, an isotope with a low cosmogenic background and an elevated "bomb-pulse" signal due to atmospheric nuclear tests in the 1950s and 1960s. Seven pools show clear evidence of bomb-pulse chloride, and nine show pre-bomb cosmogenic background levels. All four pools that are within 170 m of the ground surface contain bomb-pulse chlorine-36, while deeper pools show no clear relationship between depth and chlorine-36 levels. The three deep pools with elevated chlorine-36 apparently capture local fast infiltration pathways through the vadose zone. Using GIS software, we have examined the locations of the bomb-pulse pools relative to surface topography, surface catchment areas, and mapped photolineaments. A simple model based on these variables can explain the observed chlorine-36 distribution. It predicts that a pool will contain bomb-pulse chlorine-36 if it is within a certain distance of the surface, is below a very large surface catchment, or is within a certain distance of a lineament intersection lying within a surface catchment area. The model, applied to as-yet-unsampled pools in Lechuguilla's North Rift and Southwest Region, predicts that bomb-pulse chlorine-36 will be detected at Moonbeam, Dilithium, Tower Place, Atlantis and Aqua Velvet Pools, but not at Yo Acres, Lake Margaret, Pearlsian Gulf, Voids or Briny Pool.

We also compared GPS collar PARs under varying levels of cloud cover and within differing daily time periods. We recorded a mean PAR of 69% (n = 10 elk, s = 14%) for collared elk. Multiple regression analysis of seasonal home range characteristics indicated that vegetation cover type and slope, either as individual variables or in combination with one another, were not significant predictors of GPS collar PARs. We did not observe statistical differences in position acquisition rates between cloud cover classes or varying cloud base heights. PAR was significantly higher between 1600 h and 2000 h (mountain standard time) compared to 0000 h-1200 h, which may have been due to elk behavior. We believe using GPS collars is a more effective and efficient method of tracking elk in our study area than using very-high-frequency (VHF) collars since GPS collars can be programmed to obtain fixes automatically, have fewer logistical problems, and are more economical with long-term data collection efforts.

AN - 76984711; 11258937 AB - Human flap endonuclease-1 (FEN-1) is a member of the structure-specific endonuclease family and is a key enzyme in DNA replication and repair. FEN-1 recognizes the 5'-flap DNA structure and cleaves it, a specialized endonuclease function essential for the processing of Okazaki fragments during DNA replication and for the repair of 5'-end single-stranded tails from nicked double-stranded DNA substrates. Magnesium is a cofactor required for nuclease activity. We have used Fourier transform infrared (FTIR) spectroscopy to better understand how Mg2+ and flap DNA interact with human FEN-1. FTIR spectroscopy provides three fundamentally new insights into the structural changes induced by the interaction of FEN-1 with substrate DNA and Mg2+. First, FTIR difference spectra in the amide I vibrational band (1600-1700 cm(-1)) reveal a change in the secondary structure of FEN-1 induced by substrate DNA binding. Quantitative analysis of the FTIR spectra indicates a 4% increase in helicity upon DNA binding or about 14 residues converted from disordered to helical conformations. The observation that the residues are disordered without DNA strongly implicates the flexible loop region. The conversion to helix also suggests a mechanism for locking the flexible loop region around the bound DNA. This is the first direct experimental evidence for a binding mechanism that involves a secondary structural change of the protein. Second, in contrast with DNA binding, no change is observed in the secondary structure of FEN-1 upon Mg2+ binding to the wild type or to the noncleaving D181A mutant. Third, the FTIR results provide direct evidence (via the carboxylate ligand band at 1535 cm(-1)) that not only is D181 a ligand to Mg2+ in the human enzyme but Mg2+ binding does not occur in the D181A mutant which lacks this ligand.

AN - 76968373; 11246132 AB - Inhalation of particulate beryllium (Be) and its compounds causes chronic Be disease (CBD) in a relatively small subset ( approximately 1-6%) of exposed individuals. Hallmarks of this pulmonary disease include increases in several cell types, including lung fibroblasts, that contribute to the fibrotic component of the disorder. In this regard, enhancements in cell proliferation appear to play a fundamental role in CBD development and progression. Paradoxically, however, some existing evidence suggests that Be actually has antiproliferative effects. In order to gain further information about the effects of Be on cell growth, we: (1) assessed cell proliferation and cell cycle effects of low concentrations of Be in normal human diploid fibroblasts, and (2) investigated the molecular pathway(s) by which the cell cycle disturbing effects of Be may be mediated. Treatment of human lung and skin fibroblasts with Be added in the soluble form of BeSO(4) (0.1-100 microM) caused inhibitions of their growth in culture in a concentration-dependent manner. Such growth inhibition was found to persist, even after cells were further cultured in Be(2+)-free medium. Flow cytometric analyses of cellular DNA labeled with the DNA-binding fluorochrome DAPI revealed that Be causes a G(0)-G(1)/pre-S phase arrest. Western blot analyses indicated that the Be-induced G(0)-G(1)/pre-S phase arrest involves elevations in TP53 (p53) and the cyclin-dependent kinase inhibitor CDKN1A (p21(Waf-1,Cip1)). That Be at low concentrations inhibits the growth of normal human fibroblasts suggests the possibility of the existence of abnormal cell cycle inhibitory responses to Be in individuals who are sensitive to the metal and ultimately develop CBD.

The Japanese islands comprise one of the more volcanically active regions on Earth and the risk of volcanism to a geologic repository is being evaluated as part of the Japanese high-level radioactive waste-disposal program. One hazard that is being evaluated as part of volcanic risk assessment is the possible intersection of a repository by a dike, if a composite volcano were to form near a repository during the long (100 k.y.) performance period of the repository. In this paper we use the characteristics of a well-exposed radial dike system at the Summer Coon volcano in Colorado to define Monte Carlo simulations that estimate the probability of a dike intersection of a repository as a function of volcano distance, dike length and density, and repository area. The models indicate that the probability of intersection declines rapidly as a function of distance from a volcano, as dike density decreases due to the radial dike geometry. The probability of intersection for a mafic dike set with shorter average length declines more rapidly than that of a silicic dike set with longer average length. However, mafic dikes have a higher probability of intersecting a repository close to a volcano (<5-6 km) because they are more numerous than longer silicic dikes. The probability of a silicic dike intersecting a repository is < or =10 (super -2) at distances greater than 15 km from the volcano, decreasing to < or =10 (super -4) at distances greater than 30 km.

The morphology of the diamonds ranges from skeletal forms composed of thin {111} plates through cuboid and octahedral forms. Included within the diamonds is a diverse suite of nanometric oxides, suggesting that the C-O-H fluid from which the diamonds grew may have carried chemical components derived from both the sediments and the mantle. The spectrum of morphologies and their abundant tiny inclusions can all be explained by a simple model based on the ratio of the rate at which {111} plates grow and the rate of random nucleation of new plates at their edges.

Some seams in China have been burning for over two hundred years! Fires often start in the abandoned workings or workings of a coal mine. Fires in abandoned workings are the most problematic. Major causes of fires include cutting and welding with torches, explosives, electricity, cigarettes, ignition of mine gas, surface fires transmitted to underground seams, and spontaneous combustion. Mine fires produce environmentally catastrophic effects ranging from the emission of poisonous asphyxiating gases into the atmosphere to condensation products that pollute streams and soil. Minerals condensed from burning coal form as gas exhaled from surficial vents and cracks, waste piles, and surficial coal seams cools and condenses. The exhalation-condensation process is analogous to the way minerals form in fumarolic environments. Common gases associated with coal fires are carbon monoxide (CO), carbon dioxide (CO (sub 2) ), hydrogen (H (sub 2) ), nitrogen (N (sub 2) ), oxygen (O (sub 2) ), hydrogen sulfide (H (sub 2) S), oxides of sulfur (SO (sub x) ) and nitrogen (NO (sub x) ), and various hydrocarbons including methane (CH (sub 4) ). Minerals condensed from coal gas indicate that a variety of other gases are produced during combustion. Using thermodynamic loop (TL) analysis, it is possible to calculate P-T stability diagrams for gaseous condensates including orthorhombic sulfur (S), selenium (Se), and galena (PbS). The significance of the P-T diagrams is that they reveal environmental conditions that tend to favor the condensation of gaseous exhalations as opposed to the absorption of those exhalations into the atmosphere.

A comprehensive understanding of the fracture distribution and hydrogeomechanical processes occurring during operation provides valuable information for reservoir development and optimization of production. Some of this information can be obtained from well logs, but they only provide direct information about conditions near the well. Microseismic (MS) monitoring techniques can be primary methods for obtaining detailed information about reservoirs and fracture systems at locations as far as 1 km from boreholes.

In response to changes in atmospheric circulation, stronger cyclonic circulation is present in Arctic sea ice and upper ocean in the late 1980s and early 1990s as compared to the early 1980s, manifested as the weakening of the Beaufort Gyre and the shifting of the Transpolar Drift Stream. Corroborating previous studies, ice divergence in the central Arctic Ocean is highly correlated with surface atmospheric vorticity in summer, suggesting that summer atmospheric circulation is more important than winter for inducing interannual variability of the central Arctic ice divergence and growth rate. The weakening of the summer atmospheric cyclonic circulation from the earlier period to the later period over the Canadian Basin leads to decreased ice divergence there, which then has significant impact on the ice growth rate by reducing ice formation in fall and winter. For the 15 year period, variability in the spatial distribution of ice concentration and thickness is largely determined by the ice dynamics, which is dominated by the atmospheric circulation, except over the Greenland and Labrador Seas, where the ice thermodynamics plays a more important role. The model simulation supports the recent observations of increased presence of Atlantic Water in the Arctic Ocean. The spatial pattern of warming and salinization of the Arctic Atlantic layer follows the pathways of the strengthened boundary currents along the continental slopes and over the ridges, thereby slowly spreading more Atlantic Water downstream from the eastern Arctic into the western Arctic. The integrations with and without surface temperature restoring indicate that the restoring leads to a warmer ocean surface temperature. However, the restoring has little impact on its interannual variability for the 15 year period. Copyright 2001 by the American Geophysical Union.

This study focuses on the effects of surface tension on the evolution of vortex pairing in a two-dimensional mixing layer. Several types of interface pinch-off are observed and the corresponding mechanisms are discussed. The contribution of surface tension to the flow kinetic energy is mainly negative. Part of this kinetic energy can be transformed to potential energy stored in the surface tension. The contribution of surface tension to the flow enstrophy is positive and small vortices are generated near interfaces. Broken interfaces and small vortices near interfaces dominate the late stage of flow fields with strong surface tension.

Raman spectroscopy can be useful as a screening technique at the percent level (by mass) if interference from soil fluorescence can be overcome. Multivariate analysis is shown capable of both extracting the Raman signatures of EMs from spectra obscured by large fluorescence backgrounds caused by soil components, and generating calibration curves for the EMs at the percent level.

AN - 70859920; 11351727 AB - We have studied the photochemical reduction of uranyl to generate UO2 without hydrogen reduction. Formate and oxalate were examined as potential reductants that only lead to CO2 production as a side product. Despite the similar nature of the two reductants, the mechanism for quenching the uranyl excited-state changes drastically and leads to dramatically different chemistry at low pH. Oxalate quenches by unimolecular electron transfer and formate quenches by H-atom abstraction. Because of the change in mechanism, photochemical reduction of uranyl with formate works with high efficiency at low pH while photolysis in the presence of oxalate leads to the generation of CO and no net uranyl reduction. Photochemical reduction of uranyl with formate at low pH leads to U(IV) in solution that can then be precipitated as UO2 by simply raising the pH with yields as high as 99.992%.

AN - 70607742; 11217722 AB - The Industrial Hygiene and Safety Group at Los Alamos National Laboratory (LANL) developed a database application known as IH DataView, which manages industrial hygiene monitoring data. IH DataView replaces a LANL legacy system, IHSD, that restricted user access to a single point of data entry needed enhancements that support new operational requirements, and was not Year 2000 (Y2K) compliant. IH DataView features a comprehensive suite of data collection and tracking capabilities. Through the use of Oracle database management and application development tools, the system is Y2K compliant and Web enabled for easy deployment and user access via the Internet. System accessibility is particularly important because LANL operations are spread over 43 square miles, and industrial hygienists (IHs) located across the laboratory will use the system. IH DataView shows promise of being useful in the future because it eliminates these problems. It has a flexible architecture and sophisticated capability to collect, track, and analyze data in easy-to-use form.

The retardation of contaminants is often greatest at boundaries between minerals and in fractures and pore spaces. The investigation of the spatial distribution of sorbed contaminants along these boundaries requires micro-analytical techniques. The sorption of dissolved Pu(V) on a natural zeolitic tuff from Yucca Mountain (NV, USA) was examined using microautoradiography (MAR), X-ray diffraction (XRD), electron microprobe (EM) techniques, and synchrotron-based micro-X-ray fluorescence (micro-SXRF). The tuff contained a heterogeneous distribution of zeolites and trace quantities of smectites, Fe oxides (hematite), and Mn oxides (rancieite), which are present as fracture fill and pore space materials. Micro-SXRF studies showed that Pu is mostly associated with bodies of smectite plus Mn oxides, which were typically elevated in Ce, Ga, Nb, Pb, Y, Ca, Ti, and Zn. Sorbed Pu was not associated with Fe-rich bodies, which were enriched in Cl and Rb. Results of the MAR studies were complementary to that of the micro-SXRF studies in that Pu was associated with similar elements in the tuff. Indirect detection of Pu by EM or micro-SXRF (by analyzing Ag developed on the MAR photoemulsion) was a more sensitive method for detecting lower levels of sorbed Pu than the direct detection of sorbed Pu via micro-SXRF in the absence of the photoemulsion.

AN - 19441293; 7115141 AB - We undertook studies of the chemical and lead (Pb) isotopic compositions of reef corals offshore of Oahu, Hawaii in order to establish the fate and transport of nonpoint source metal pollution in urbanized Hawaiian coastal waters. Using aragonite-seawater Kd's, we hypothesized that absolute metal concentrations, trends, and changes due to economic or regulatory impacts on human activity could be read from the coral reef record. Metal concentrations and Pb isotope measurements were therefore taken on coral samples from several offshore sites spanning heavily impacted urban to lightly impacted rural conditions. Direct sampling of these same parameters in seawater and urban storm runoff, and measurements of Pb isotopes in juvenile fish otoliths provided independent tests of chemical parameters calculated from coral data. Stable Pb isotope ratios measured on seawater samples and in otoliths spanned a 206Pb/204Pb range18.32 to 19.42, while measurements on corals collected at the same locations ranged from 18.32 to 18.52. The restricted range of Pb isotopes measured in corals strongly resembled our data measured on storm water samples and in urban sediments, strongly suggesting that these corals accumulated most of their Pb by incorporation from storm- derived particles. Dissolved Pb concentrations were overpredicted by coral concentrations where coral and water isotopic compositions were most dissimilar. In areas where coral and seawater exhibited greater isotopic similarity, seawater Pb concentrations were predicted accurately. Dissolved elemental concentration predictions (Pb, Zn, Cu, Cd) varied in accuracy, with the level of agreement between coral-predicted and actual dissolved load concentrations in the order Pb (greatest agreement), Zn, Cd, Cu (worst agreement). While historical trends are evident in many of the trace metal profiles in our corals, these may not reflect any simple measure of water quality (i.e. dissolved load). A range of factors, such as proximity of colonies to sedimentary input during storms, tidal or current generated mixing, and mode of metal incorporation may influence the relationship between coral and seawater trace metal concentrations. Efforts to use corals as proxies for seawater chemistry in "real world" situations must be used with caution.

This collaborative work is focused on designing and building these new models, generating synthetic seismic data through simulated surveys of various geometries, and using these data to test and validate new and improved seismic imaging algorithms. The new models will be both 2- and 3-dimensional and will include complex velocity structures as well as anisotropy and attenuation. Considerable attention is being focused on multicomponent acoustic and elastic effects because it is now widely recognized that converted phases could play a vital role in improving the quality of seismic images. An existing, validated 3-D elastic modeling code is being used to generate the synthetic data. Preliminary elastic modeling results using this code are presented here along with a description of the proposed new models that will be built and tested.

Controlled laboratory experiments were performed where mechanical stress oscillations at 100 Hz or less were applied to sandstone cores while flowing oil and/or brine at constant flow rates. Steady-state flow and simulated flooding experiments indicated that stress stimulation causes significant changes in the ability of one fluid to displace the other and on the preference that the rock has for trapping one fluid over the other. For Berea sandstone, which is highly water wet, stress stimulation caused oil production to be impeded during water floods and caused the bulk fluid pressure drop across the core to increase during steady-state simultaneous flow of oil and brine. A possible explanation of these observations is that stimulation caused the core to become more oil wet. Field stimulation tests on producing reservoirs at Lost Hills, California were performed using a downhole fluid pressure pulsation device. Stimulation was applied in one well for 50 days total during July - November 2000. Two groups of producing wells were monitored for changes in oil cut and oil production during the test. A control group of 26 wells displayed an oil-cut increase of 29% and an oil production increase of 26% which are clearly correlated with the stimulation treatment. A larger group of 60 wells showed 11% oil-cut and 17% production increases. Similar increases were observed during the October 1999 Hector Mine earthquake, magnitude 7.1, in the Mojave Desert about 230 miles from Lost Hills. Downhole seismic monitoring of the stimulation wavefield is being used to help quantify the frequency range and energy threshold required for effective production enhancement.

Gas is produced from a thick sequence of tight gas sandstones, a reservoir highly representative of low-permeability gas resources that require routine hydraulic fracturing for economic production. Event locations were re-computed after obtaining higher-precision arrival-time data by manually picking the data in a spatial sequence, allowing us to visually correlate waveforms of adjacent source locations. The new arrival time data result in 4- fold improvement in location precision, resulting from a 4-fold reduction of residual standard deviations. The new locations show remarkable vertical containment within individual, targeted sands, indicating little or no communication between discrete perforation intervals over an 80 m stimulated section. Similarity of adjacent-source waveforms throughout the data set, along with systematic changes of phase amplitude ratios and polarities, indicate a fairly uniform focal mechanism occurring over the entire fracture length. Composite focal mechanisms indicate both left- and right-lateral strike-slip faulting along near-vertical fractures striking subparallel to maximum horizontal stress. The focal mechanisms and hypocenters are consistent with an activation of the reservoir's natural fracture system, which is known to be dominated by vertical extension fractures trending subparallel to the expected hydraulic fracture orientation.

The physical model was constructed at the University of Houston from a scaled-down rendition of the SEG/EAGE salt structure. Two simulated marine surveys were collected from it: one was a conventional towed streamer survey, the other a vertical receiver cable survey. The towed streamer data set is the focus of this study. 2-D prestack depth migrations were done to establish that imaging with a subset of data from a line provides a reliable and adequate image. A 3-D prestack depth migration of one line provides a better image than the 2-D image and improved imaging of some features than to the 2-D images.

The method uses the Pade approximation of an exponential term in the formal solution of the one-way wave equation. It can produce high-quality images of complex structures with fewer numerical artifacts than those obtained using a finite-difference parabolic-equation scheme that is based on the Pade approximation of the square-root operator in the one-way wave equation. For a given model, the split-step Pad'e method is more efficient than the finite-difference parabolic equation scheme because the former can use a larger grid spacing than the latter.

AN - 71159519; 11548328 AB - Metal tritides with low dissolution rates may have residence times in the lungs which are considerably longer than the biological half-time normally associated with tritium in body water, resulting in long-term irradiation of the lungs by low energy beta particles and bremsstrahlung X rays. Samples of hafnium tritide were placed in a lung simulant fluid to determine approximate lung dissolution rates. Hafnium hydride samples were analysed for particle size distribution with a scanning electron microscope. Lung simulant data indicated a biological dissolution half-time for hafnium tritide on the order of 10(5) d. Hafnium hydride particle sizes ranged between 2 and 10 microns, corresponding to activity median aerodynamic diameters of 5 to 25 microns. Review of in vitro dissolution data, development of a biokinetic model, and determination of secondary limits for 1 micron AMAD particles are presented and discussed.

AN - 71113984; 11518499 AB - The purpose of the present study was to examine mitochondrial function in differently transformed cells relative to their tumorigenic state and proliferative activity in vitro. An established two-step carcinogenesis model consisting of immortal and tumorigenic rat embryo fibroblasts that can be cultured as monolayers and multicellular spheroids was investigated. Flow cytometric measurements were carried out using the two mitochondrial-specific fluorochromes rhodamine 123 (Rh123) and 10-N-nonyl acridine orange (NAO), in combination with the DNA dye Hoechst 33342 for simultaneous cell cycle analysis. Since the accumulation of Rh123 depends on mitochondrial membrane potential, Rh123 fluorescence intensity gives an estimate of mitochondrial activity per cell, as determined by both overall mitochondrial function and mass. In contrast, NAO uptake reflects mitochondrial mass only, as it binds to cardiolipin in the inner mitochondrial membrane independently of membrane potential. Aliquots of cell suspensions derived from exponential monolayer, confluent monolayer, and a range of sizes of multicellular spheroids were stained with either Rh123 or NAO and Hoechst 33342, then mitochondrial mass and activity per unit cell volume and cellular DNA content were measured by flow cytometry. Differences in the average mitochondrial activity per cell in different cell lines and culture conditions were primarily due to alterations in cell volume. Importantly, tumorigenic conversion by ras-transfection did not consistently change mitochondrial activity per unit cell volume. The mitochondrial mass per unit cell volume increased for all cells when cellular quiescence was induced, either in monolayers or spheroids. However, mitochondrial function (activity/mass) decreased when cells became quiescent, resulting in a positive correlation between mitochondrial function and S-phase fraction, independent of transformation status or culture condition. We conclude that mitochondrial function reflects proliferative activity rather than tumorigenic conversion.

We present a new approach for determining minimum magma residence times which involves dating phenocrysts in a magma using (super 226) Ra- (super 230) Th disequilibria, and apply this approach to the early phase of the 1955 east rift eruption at Kilauea. When fractionation of Ra from Ba (a proxy for initial Ra in the crystals) during crystal growth is considered along with the effects of inclusions in the minerals, the data are consistent with co-precipitation of plagioclase and clinopyroxene from a melt represented by the groundmass at a mean age of 1000 (super +300) (sub -400) a. Unless a significant fraction (>30%) of the crystals are remnants from an earlier batch of evolved magma in the system, these data constrain the minimum magmatic residence time to be approximately 550 yr, considerably longer than most previous estimates of storage time at Kilauea as well as those for some other basaltic systems. For the temperature interval of augite+plagioclase growth in the early 1955 magma, a maximum constant cooling rate of 0.1 degrees C/yr (1X10 (super -5) degrees C/h) is derived from the minimum magmatic residence time of 550 yr. The total magma storage time would be >2500 yr if this cooling rate applied to the entire thermal history of the magma, although a more complex cooling history where cooling rates were more rapid early in the storage history is permissive of a total residence time which is not much longer than 550 yr. The disparate estimates of magma residence at Kilauea may reflect the uncertainties in the methods of estimation in addition to true variations in storage time for different batches of magma. More work is necessary in order to determine whether a long residence time is characteristic of rift zone lavas and/or of Kilauean lavas in general.

In addition, many types of organic substances (volatile and semivolatile organic compounds, organochlorine pesticides, polychlorinated biphenyls, high explosives, and dioxin and dioxin-like compounds) were assessed in soils from LANL, perimeter, and regional sites after the fire. Results show that impacts to regional, perimeter, and on-site (mesa top) areas from smoke and fallout ash as a result of the Cerro Grande fire were minimal.

Low rainfall and a thick unsaturated zone are important physical attributes of the site because the quantity of water likely to reach the waste and the paths and rates of movement of the water to the saturated zone under likely future climates will be major factors in estimating the concentrations and times of arrival of radionuclides at the surrounding accessible environment. The framework for understanding the hydrologic processes that occur at this site and that control how quickly water will penetrate through the unsaturated zone to the water table has evolved during the past 15 years. Early conceptual models assumed that very small volumes of water infiltrated into the bedrock, that much of the infiltrated water flowed laterally within the upper nonwelded units because of capillary barrier effects, and that the remaining water flowed down faults with a small amount flowing through the matrix of the lower welded, fractured rocks. When evidence accumulated indicating that infiltration rates were higher than initially estimated, and that mechanisms supporting lateral diversion did not apply at these higher fluxes, the flux calculated in the lower welded unit exceeded the conductivity of the matrix. This required water to flow vertically in the high-permeability fractures of the potential repository host rock. The development of numerical modeling methods evolved concurrently with the conceptual model in order to account for the observations made at the site, particularly fracture flow deep in the unsaturated zone. This paper presents the history of the evolution of conceptual models of hydrology and numerical models of unsaturated zone flow at Yucca Mountain, Nevada.

Specifically, a relative increase in the carbonic component of the fluid within ductily deforming, quartzo-feldspathic host rocks resulted in a shift in fluid characteristics from a wetting to a nonwetting state. It is hypothesized that nonwetting, carbonic fluids dynamically influence pore-space geometry in a manner that reduces transmissivity. In the footwall, localized bending strain and exhumation may cause transiently high pore fluid pressure resulting in an environment that is conducive to brittle failure. This path of evolution from wetting to nonwetting, fluids is documented by fluid inclusion observations from kinematically referenced fluid inclusion arrays. Carbonic fluids are only found in association with brittle structures that clearly crosscut ductile footwall fabrics. Important questions are related to this process: (1) During ductile deformation at mid-crustal conditions, where were the initial, wetting fluids derived?; and (2) By what mechanisms were these fluids driven to more carbonic, nonwetting compositions? By combining textural, fluid inclusion, isotopic analysis, and mass balance considerations it may be possible to fully address both of these important questions. Of particular interest is the hypothesis that shear-zone fluids were driven to nonwetting, carbonic compositions by the retrograde formation of chlorite. The formation of chlorite is known to occur within the same temperature and pressure ranges derived for the earliest phase of brittle failure in the footwall (450 degrees -600 degrees C and 400-700 Mpa). Also, for every mole of chlorite formed, 4 moles of water are consumed, which equates to an increase of 0.016 modal abundance of chlorite to shift the bulk fraction of X (sub CO2) from 1% to 5% in a closed system. Preliminary stable isotope data from fault related fluid inclusions indicate that the water has low delta D and delta (super 18) O values between -64 to -28 per mil and -14 and -9 per mil, respectively. delta (super 13) C-CO (sub 2) values between -9.7 and -2.6 indicate that the carbonic phase is from a mixed source. Although the results from the isotopic analyses are inconclusive, other lines of evidence are consistent with chlorite formation influencing fluid composition.

Hydrothermal models (2D, 3D) of intrusions into the middle crust indicate that an advectively driven thermal pulse may develop after the initial conductive thermal peak when background geothermal gradients and permeability (K) are of sufficient magnitude. This second thermal event is much longer lived than the initial conductive thermal spike in rocks close to the intrusion and is preceded by a period of high fluid flux. As an example, contact aureoles generated from the intrusion of a tabular pluton, at 875 degrees C and 12 km into host rocks with a K = e-16m (super 2) and background temperatures (T) that varied along a linear geothermal, are examined. For a gradient of 36 degrees C/km, a rock positioned 125 m horizontally from the end of the pluton experiences a rapid T increase to a maximum of 630 degrees C. After cooling to ca. 570 degrees C, thermal forces are sufficient to begin driving convection. Advective heat transfer then causes T to rise to 600C at 480,000 yrs and remain above 570 for about 60,000 yrs. Instantaneous fluid flux is maximum at ca. 450,000 yrs, prior to the second thermal peak and subsequent to the initial thermal pulse. In contrast, decreasing background T's to 28 degrees C/km, causes not only a lower maximum T, 590 degrees C, but a substantially lower secondary thermal maximum, 510 degrees C. However, maximum fluid flux also precedes the second thermal event. In the 36 degrees C/km case, the second thermal pulse is of sufficient duration for reaction rates to produce mineral textures consistent with regional metamorphism. Advective circulation of heat provides a mechanism for hydration of an earlier formed assemblage prior to slow reheating. Thus, advection may be an important control of the thermal overprinting observed in metamorphic terranes.

The basis of this research requires accurate phase and noise amplitude measurements, generally involving frequencies of about 1 Hz and higher [for example, P (sub n) /(0.75-1.5 Hz)]. Here, we examine the differences between amplitude measurements made in the time domain and measurements made in the frequency domain and how those differences might affect regional seismic discrimination and detection threshold estimates. We have worked with WMQ data for several years. We have retrieved and measured seismograms recorded at WMQ from about 1800 events from throughout central Asia for the years ranging from 1986 to 2000. Event-station distances range out to about 2500 km and event magnitudes range from about m (sub b) 2.5 to over 6.0. We measured WMQ BHZ seismograms over the P (sub n) , P (sub g) , S (sub n) , and L (sub g) phases using time domain root mean square (RMS) and frequency domain Fast Fourier Transform (FFT) methods. For RMS amplitude measurements, we use the instrument response to correct the entire seismogram into displacement. We then bandpass filter, cut the time-window based on velocity and event-station distance, and measure amplitude as a Log (sub 10) RMS value. For the spectral method, we cut the phase time-window from a seismogram that has been instrument-corrected into acceleration. We then taper, FFT, and divide by angular frequency twice to convert into displacement. We initially instrument-correct the seismogram into acceleration in an effort to reduce the large amplitudes of the longer period microseism relative to the shorter-periods that are of interest to us for discriminant tests. We smooth and resample the spectra at a rate of 0.05 Log (sub 10) frequency. To compare RMS and spectral amplitudes for a given event, phase, and band we average the displacement spectra over the same band used during the RMS procedure. When comparing the two methods, we convert the RMS amplitudes to pseudo-spectral amplitudes following Parseval's Theorem. In general, RMS amplitudes of all phases are slightly larger than the corresponding spectral amplitudes. This is because Log (sub 10) averaging of the spectral amplitudes emphasizes the higher frequencies within a band. These higher frequencies are lower in amplitude because of the "roll-off" in frequency of the seismic source and the greater attenuation at higher frequencies along the seismic path. The actual ratios obtained using the two methods tend to be nearly the same. This is because the small offsets in the RMS amplitudes relative to the spectral amplitudes are about the same for both phases, and the offsets therefore cancel when the RMS ratio is formed. We found that spectral measurements of short P (sub n) windows (out to event-station distances of about 700 km) are sometimes unusually large compared to the RMS measurements. This occurrence is most pronounced for low-magnitude events when the measurement window is short. Initially we assumed the problem was with our frequency-domain measurements, but we traced this occurrence to a delay introduced by applying a one-pass filter during the time-domain measurement procedure. The delay was moving the P (sub n) energy down the trace and outside of the measurement window. After changing to a two-pass filter, the RMS amplitudes closely matched the spectral amplitudes.

Bolides represent a source of significant natural impulsive signals that can be detected by infrasound arrays and networks and may not have detections by other technologies. As more International Monitoring System (IMS) infrasound stations come online, detections of these events will increase. Analysis of these multiple-station event detections will allow tuning of detection and location algorithms. Work by various groups on the April 2001 event already has shown this. We will present data from all 13 events, detected by one to eight stations (not all of which are IMS); however, more detailed results will be made for the 4/23/01 and 8/25/00 events for which some space-based data have been released. Some results on the bolide events will illustrate the features of Infra_tool, an infrasound analysis tool for use within MATSEIS. We will also review some recent work and analysis of infrasound from earthquakes observed with Los Alamos National Laboratory (LANL) arrays. This data set illustrates the value of using wind-corrected amplitudes in the analysis: These natural impulsive events have many of the characteristics of interest to the IMS. Such data will be essential for exercising and refining detection and location algorithms and thus calibrating the infrasound network.

The goal of the model maker is to provide a means for producing 1-D, 2-D and 3-D gridded or layered velocity and attenuation models for travel-time and full waveform synthetic seismic estimates. In the implementation of this code, we include the capability to produce multiple models based on the same a priori information by allowing for multiple construction rules. A priori rock property information can take the form of surface discontinuities (such as the crust mantle interface, topography, and basins) or any kind of 1-D, 2-D, or 3-D regional information. Because of the flexibility of the tool, models may be readily updated as new information becomes available. Our current model includes regions of North Africa, Europe, and Asia and is based on the previous Los Alamos National Laboratory model for China, the Maxwell (SAIC) global surface wave model and the Lawrence Livermore National Laboratory Middle East/North Africa/Former Soviet Union model. Models are validated by comparing model-based and empirically derived correction surfaces for important stations in Western China. Waveforms from these stations for events of special interest are also used to test the accuracy of the model using a full waveform finite difference algorithm. We also test the sensitivity of the model predictions to different types of a priori data (e.g. structural interfaces like the Moho and 1-D velocity models for geophysical provinces.

The resulting refined tomographic model blends into these prior background models. Moreover, the error budget is well established in a Bayesian framework. We assume a general linear Gaussian (least squares) model, where the covariance matrix is partitioned into data and prior model components. Uncertain data are naturally down weighted and certain model components will be subject to small perturbations. Bayesian attenuation tomography (Tarantola, 1987) is being incorporated into the Magnitude and Distance Amplitude Correction (MDAC) methodology used for amplitude corrections to seismic discriminants (Taylor et al., 1999). Because a signal-to-noise criterion is used to select amplitudes for the inversion, the data are left-censored and the resulting Q (sub 0) models will be biased high. We examine the utility of the Expectation Maximization (EM) algorithm to the left-censored data problem (Dempster et al., 1977). In this case, we can define only an upper bound to measured amplitudes based on pre-phase noise. The EM algorithm can be used to fill in the missing data values with their conditional expectation based on the relationship of amplitudes with other related completely observed variables. We have initially chosen a bivariate Gaussian model for filling in missing amplitudes based on the relationship between amplitude and pre-phase noise. The methodology can be extended to the multivariate case by the incorporation of other variables such as magnitude and distance, background noise, and Pn velocity tomography. We apply the technique to eastern Asia for Pn, Pg, Sn, and Lg signals at 1 Hz using data from 1651 earthquakes recorded at 12 stations. Tomographic patterns correlate well with those expected from geophysical considerations (e.g. high attenuation in Tibet and low attenuation up into the stable regions of Kazakhstan). Interestingly, many of the large cratonic basins surrounding the Tibet Plateau (e.g. Tarim, Junggar) show reduced attenuation. Application of the EM algorithm tends to increase attenuation in Tibet (particularly western Tibet) and the cratonic basins to the north of but not to the east of Tibet. We are refining regionalized surface slowness models in a number of regions for surface wave magnitude measurements to be used for m (sub b) --M (sub d) -M (sub s) discriminants. Regional M (sub s) can be measured at lower magnitudes through the application of phase-match filters. The filters can be constructed from tomographic group velocity maps from which path-specific dispersion curves can be calculated. Global and regional group velocity maps are available from previous studies (e.g., Stevens and Adams, 2000; Levsin et al., 2000) and Bayesian slowness tomography provides a framework for utilizing existing global and regional models as priors on which to improve resolution in specific regions. Tomography provides only an approximation to the propagation effects a seismic wave may experience. For example, phase blockage can occur over relatively short distances in the absence of any anelastic effects. Station-centric kriged amplitude or slowness correction surfaces on top of the tomographic models may assist in quantifying departures from the smooth tomographic model (Pasyanos, 2000).

For example, magnitude and distance amplitude corrections (MDAC) have been developed for regional discrimination, but they rely on stable moment estimates. We develop a catalog of regional earthquakes in eastern Asia with estimated seismic moments, source mechanisms, and depths using regional seismic data. A catalog of regionally estimated seismic moments, source mechanisms, and depths is also a useful tool for magnitude calibration and regional characterization. We are particularly interested in constraining seismic moments, which are critical for calibrating regional magnitude scales with global catalogs, and in improving depth estimates for Asian events. A significant challenge of modeling small-to-moderate-size seismic sources is the necessity of relying on short-period signals with long travel paths that have substantial sensitivity to earth structure along the path. When the path effects are unknown or difficult to account for, we must rely on components of seismic signals that are minimally dependent on the structure. Although regional surface-wave phases are strongly influenced by structure, surface-wave amplitude spectra can be modeled adequately with relatively simple earth models, and these spectra carry valuable information on source character. Our efforts build on existing seismic source analysis techniques. We directly model regional seismograms where possible but combine those with surface-wave amplitude spectra observed at more distant regional stations. The inversion is performed using a grid search for strike, dip, rake, moment, and depth. Choosing suitable weights for the different data sets remains a challenge that will only be overcome with experience. Initially, all data are weighted equally by normalizing seismograms and spectra by their uncertainty and the number of observations in each data set. For larger events (M (sub w) >5) we can also include long-period (approximately 40-s period) body-wave trains, which can be modeled reliably using simple stratified earth models. The use of spectra and long-period signals is ideal for estimating the moment and faulting geometry of signals but simple least-squares norms based on these signals do not often provide satisfactory resolution of source depth (when the source is shallow). However, in cases where the long-period mechanism is relatively stable as a function of depth, we can overcome this limitation by exploiting signals more diagnostic of source depth such as teleseismic body-waveforms, broad-band Pn waveforms, or select short-period Rayleigh wave spectra. For example, once the mechanism is relatively well known, we can refine depth estimates using short-period P-waveforms using a synthetic seismogram-matching procedure that provides source depth constraints that in some cases span a few kilometers.

Herein we present some observations on the nature of kriged P-wave travel-time correction surfaces and their application to improving seismic event location in China. We have adopted the correction surface approach due to ease of implementation and the fact that empirical correction surfaces can be constructed without detailed knowledge of crustal structure. However, correction surfaces can be built on any velocity model, no matter how detailed, so that when such models do become available, surfaces can be recalculated for that model. This, in turn, enables prediction of corrections in regions lacking seismicity. We use the modified Bayesian kriging method to construct surfaces for 76 stations around Asia, analyzing travel-time data from seismic events in the United States Geological Survey Earthquake Data Reports (EDR) and the International Seismic Center (ISC) catalog. Due to limited data, we gather residuals for events throughout the crust (as defined by the 1-D global model employed) whose location accuracies range from 2-25 km. The correction surfaces are used with the EvLoc algorithm to perform regional relocations of several thousand events in the region around China. Correction surfaces dramatically improve the clustering and linearity of regional seismicity and increase the stability of EvLoc. About 50% more events are successfully relocated when surfaces are used. Comparing regional relocations to high-quality ground truth also reveals a significant quantitative improvement in location accuracy. In an effort to further improve our location ability, we are creating a comprehensive merged database for the China region, comprised of EDR, ISC, Reviewed Event Bulletin, and several regional catalogs. This database will provide the most complete record of arrivals for events in eastern Asia, and its location performance will be validated against current databases. One measure of the robustness of the kriged surfaces is their correlation; nearby stations should have similar P-wave correction surfaces. We find that surface correlation is high for nearby stations but drops off beyond about 250 km, implying that, on average, crustal structure varies rapidly across Asia. This length scale may be useful for assessing whether or not surrogates should be used in developing correction surfaces for new stations. Moreover, this correlation length can also be used to constrain the model correlation length parameter in the kriging procedure. We have performed a suite of sensitivity tests to examine the effect of depth and epicentral mislocations on travel-time residuals. These tests were performed using four closely spaced high-quality ground truth events as observed by the 76 stations for which we calculate correction surfaces. Fixing the latitude and longitude of the events and letting the origin time and depth vary, we find that there is about 0.13-sec deviation in residuals for every 10 km of depth error. Epicentral mislocations result in P-wave residual errors of about 0.75 sec per 0.1 degrees . When compared to the root-mean-square residual value of about 1.9 sec, effects due to depth errors and depth averaging are minimal.

Comparisons of instantaneous spatially distributed upwind fluxes with values of groundbased measured fluxes using eddy correlation techniques and other micrometeorological instruments, were conducted for two different dates. Results show considerable differences between the fluxes that can be attributed to advection, canopy heat storage and wind variability. A careful footprint analysis will need to be conducted in the future to better match the ground-based and aircraft measurements.

Extending approaches to whole basins or larger regions is difficult due to issues related to landscape heterogeneity and scale. Reliable areal estimates of ET are essential for accurate modelling of the hydrological cycle and for assessing water-use of different ecosystems. A riparian corridor along the Rio Grande (USA) dominated by Tamarisk (salt cedar) is being studied to determine daily and total seasonal water-use. Local estimates of ET in the Tamarisk were made using eddy covariance instrumentation mounted on two towers. Radiometric temperature at the top of the canopy was also measured using a fixed-head infrared thermometer. The combination of these data will be used to evaluate evapotranspiration estimates along the corridor using data remotely sensed from an aircraft platform that have been acquired periodically for a large extent of the riparian zone.

CR cover large expanses of walls and ceilings in Lechuguilla and Spider caves, and are now being reported from other caves. Levels of iron, and to a lesser extent manganese, in oxides in corrosion residues, are high (25-80 and 21 wt% respectively) and demonstrate a high degree of enrichment in the corrosion residues over what is present in the bedrock, negating the hypothesis that these materials are simply the detrital products of corrosive air. Underlying the CR is a layer of soft altered carbonate host rock (termed "punk rock") that exceeds 10 cm. Studies of bacterial metabolic activity within CR and punk rock demonstrated the presence of a moderately large, actively respiring, morphologically diverse microbial community. To assess the possibility that CR is formed by microbial processes, we carried out a culture-independent, small subunit ribosomal RNA (SSU rRNA) sequence-based study of the microbial communities. DNA was extracted from CR samples from two sites approximately 300 m below the surface, and from cultures of iron- and manganese-oxidizing bacteria; rRNA genes were amplified by PCR, cloned, and sequenced. An analysis of the resultant clones revealed that the dominant clone-types from the two sites grouped with low-temperature archaea in both the crenarchaeota and euryarchaeota kingdoms, or with members of the lactobacilli. In many cases, similarity values to database sequences were extremely low indicating a lack of known close relatives. Other clone sequences were most closely related to those of manganese-oxidizing bacteria, providing support for our hypothesis that microorganisms may assist in corrosion of the host rock, liberating Fe and Mn for oxidation as an energy source, and deposition of secondary Fe and Mn minerals in CR.

The dust from large asteroid impacts would produce worldwide darkness lasting several months that may kill more people by mass starvation, especially in developing countries, than will tsunami, but the dust should not severely affect economic infrastructure. The tsunami may even kill more people in developed countries with large coastal populations, such as the United States, than the starvation resulting from the darkness. At Los Alamos we are in the middle of a systematic study of asteroid tsunami. The study is divided into three parts: A determination of those regions of Earth that are most susceptible to asteroid tsunami by simulating the effect of an asteroid impact into mid-ocean, the simulation of the formation of the initial crater and the waves generated by it by use of a SPH code, and a Monte Carlo study of the accumulative effect of many small impactors on some of the more strategically valuable regions that we find to be particularly vulnerable in the first part of this study. The first part of the study is well underway. Progress has been made on the other two. The critical factor in the third part of the study is to accurately determine the dispersion in the waves produced by the smaller impactors. Dispersion may greatly reduce the effectiveness of the smaller impactors at large distances from the impact point. We wish to understand this effect thoroughly before performing the Monte Carlo study. We have modeled the effect of mid-Atlantic and mid-Pacific impacts with craters 300 and 150 km in diameter. The larger of these craters would be produced by a KT-size impactor. The code has been progressively improved to eliminate problems at the domain boundaries, so it now runs until the tsunami inundation is finished. We find that tsunami generated by a large mid-Atlantic impactor will travel to the Appalachian mountains in the Eastern USA. We find that the larger of these two mid-Atlantic impacts would engulf the entire Florida Peninsula. The smaller one would inundate the eastern third of the peninsula while a tsunami passing through the Gulf of Cuba would inundate the west coast of Florida. Impacts at three different sites in the Pacific show the great vulnerability of Tokyo and its surroundings to asteroid tsunami.

The clasts were partially matrix supported, and some were supported on edge. There were a number of clast-to-clast and clast-to-bone contacts. The clasts are most parsimoniously interpreted as gastroliths, making this the first set discovered in situ in this formation. The gastrolith surfaces are mostly polished. Tight spatial distribution, partial matrix support, and some instances of on-edge orientation indicate that they were deposited while contained within carcass soft tissue. Low-energy depositional conditions and apparent initial containment within soft tissue indicate that the set is complete. Surface characteristics and distributions of shape, mass, volume, and composition have been determined. More than half the clasts are less than 10 cc in volume. Drab colors indicate low selectivity by the sauropod for this character. Most of the gastroliths are chert or quartzite, but some are sandstones and siltstones. High surface reflectance values for the majority of the gastroliths is consistent with the results of previous studies on other bona fide gastroliths.

The so-called "Endee site" is characterized by Triassic redbeds (Chinle Formation) overlain by Quaternary eolian sand. Monitoring wells installed at the site revealed up to 8 ft of free product floating on a body of perched ground water within the eolian cover sand, approximately 16 to 36 ft below the site. Although yields are low and quality is poor, the redbeds are the major source of water for area ranches. However, this ground water is vulnerable to contamination due to its shallow depth. The overlying eolian sand is porous and readily takes up spills. Such contamination may first show up in local perched water bodies in the sand, where it is easier to clean up than if it reaches the redbeds, which are fairly tight. Where perched saturation is present, it serves as a buffer for the deeper groundwater, but clean-up should be prompt before contamination reaches the regional system.

The method requires special conditions to serve as IR sources or placement of an artificial IR source across the plume from the observing spectrometer. We have explored a technique that instead uses the strong radiance contrast between the volcanic gas plume and the sky, thus yielding high-quality infrared spectra in a passive manner. Observations during the recent activity of Popocatepetl demonstrate that this technique may yield nearly continuous monitoring of gas concentrations of a quality not easily acquired with other techniques.

Using empirical methods, we investigate the use of coda to determine moments and magnitudes using regional distance (to 2500 km) data from 21 stations in central Asia and China. We find source levels for bands between 33 s and 8 Hz from events recorded at Urumchi (WMQ) to be a factor of two more consistent for coda than for direct waves, for bands outside the microseism range. However, the anticipated path averaging of regional coda is insufficient to remove bias in all but the lowest frequency bands. We correct for path bias by spatially interpolating coda levels relative to m (sub b) (PDE). For higher bands (1 Hz), the spatial correction patterns vary by an order of magnitude and are similar to patterns obtained using direct L (sub g) . For the lowest band (20-33 s) the maximum spatial variation shrinks to under a factor of 4 and changes sign, reflecting effects other than crustal Q. Thus, the low frequency coda could be useful for correcting for source effects in empirical or tomographic path studies, which is currently performed using m (sub b) . After removing path bias from coda measurements, we find that amplitude measurement consistency between all 21 stations varies considerably from pair to pair (sigma = 0.12 to 0.37), with longer interstation distance, low-Q surroundings and poor site conditions yielding the least stable measurements. CMT based moments (Mw) derived from 20-33 s WMQ coda are verified by comparing with moments derived from waveform fitting studies (sigma = 0.18). We continue investigations into the transportability of regional magnitudes using the m (sub b) (L (sub g) ) scale devised by Nuttli. Previous work has shown that m (sub b) (L (sub g) ) is portable for earthquakes provided that L (sub g) attenuation is well calibrated for propagation paths. In this study, our focus shifts to explosion sources, and the question of transportability of m (sub b) (L (sub g) ) for different test sites. We revisit Nuttli's results, which were based on observations at far-regional and teleseismic distances, and depended critically upon accurate knowledge of the L (sub g) Qo. In this paper, measurements of m (sub b) (L (sub g) ) are reported for stations within 1000 km, and as such, errors due to uncertainties in the path correction are smaller than was the case for Nuttli's measurements.

It is a plateau constructed from a gently east-dipping ignimbrite sequence, separated from the Jemez Mountains by the NNE-trending Pajarito fault system on the west and the Rio Grande to the east. The Pajarito fault system appears to have been active during the Neogene, consistent with episodic volcanic eruptions within the plateau. It was reactivated following the eruption of the Upper Bandelier Tuff (1.2 Ma) and forms the current western boundary of the Espanola basin. The lithostratigraphic sequence of older rocks beneath the Bandelier Tuff is dominated by sedimentary deposits of the middle to late Miocene Santa Fe Group and Pliocene Puye Formation. The older units were superseded by late Pliocene Cerros del Rio mafic lavas, erupted from the western part of the rift floor, and Plio-Pleistocene silicic tuffs of the Bandelier Tuff and associated lavas and tuffs from the adjacent western margin. The Pleistocene Bandelier Tuff forms the uppermost bedrock on the plateau. Stratigraphic information based on core and cuttings from drilling and from outcrops on the Pajarito Plateau suggest at least three episodes of mostly mafic volcanism (10.9-13.1, 8.4-9.3, and 2.3-2.8 Ma) along the western part of the Espanola basin. The Miocene lavas of the Pajarito Plateau erupted contemporaneously with the Keres Group and the Lobato Basalt from the southern and northeastern parts of the Jemez Mountains, respectively. Geochemical analysis of the Miocene mafic lavas from the Pajarito Plateau indicate generally plagioclase- and clinopyroxene phyric alkalic and tholeiitic basalts with minor basaltic andesite and mugearite flows, whereas the late Pliocene Cerros del Rio flows consist of plagioclase- and clinopyroxene-aphyric basalts plus hawaiite, mugearite and benmoreite lavas. Eruptions differ compositionally among different regions within the Jemez volcanic field; volcanism was notably more alkalic within the southern compared with the northeastern Jemez Mountains and the Pajarito Plateau. The intercalated mafic flows within the fluvial and lacustrine rift-fill sediments establish a temporal framework for the widespread sedimentary deposits and tectonic activity at the plateau. Intense tectonic activity, subsidence, and continuous sedimentation adjacent to the western boundary fault of the Espanola basin are contemporaneous with the episodic volcanic eruptions.

A pair of simulations are considered, both of which are forced by QSCAT winds at 0.5 degree resolution, as provided by Milliff and Morzell and processed as per Chin et al. (J. Tech 15, 741-763, 1998). The effect of inertial resonance mixing is evaluated in the context of the eddy-resolving ocean model of Smith et al. (J. Phys. Ocean. 30, 1532-61, 2000). The results of this work will constrain efforts to parameterize the eddy-dependent extraction of wind energy in non-eddy-resolving ocean models.

Phylogenetic analysis is often used to study the genetic relationship among different sequences. Evolutionary models and assumptions are invoked to reconstruct trees that describe the phylogenetic relationship among sequences. Genetic databases are rapidly accumulating large amounts of sequences. Newly acquired sequences, which have not yet been characterized, may require preliminary genetic exploration in order to build models describing the evolutionary relationship among sequences. There are clustering techniques that rely less on models of evolution, and thus may provide nice exploratory tools for identifying genetic similarities. Some of the more commonly used clustering methods perform better when data can be grouped into mutually exclusive groups. Genetic data from viral quasispecies, which consist of closely related variants that differ by small changes, however, may best be partitioned by overlapping groups. We have developed an intuitive exploratory program, Partition Analysis of Quasispecies (PAQ), which utilizes a non-hierarchical technique to partition sequences that are genetically similar. PAQ was used to analyze a data set of human immunodeficiency virus type 1 (HIV-1) envelope sequences isolated from different regions of the brain and another data set consisting of the equine infectious anemia virus (EIAV) regulatory gene rev. Analysis of the HIV- 1 data set by PAQ was consistent with phylogenetic analysis of the same data, and the EIAV rev variants were partitioned into two overlapping groups. PAQ provides an additional tool which can be used to glean information from genetic data and can be used in conjunction with other tools to study genetic similarities and genetic evolution of viral quasispecies.

Performance is now the single most important issue determining the materials used, whether the intent is to produce a competitive ski for the racer or advanced recreational skier, or an 'easy to use' ski for the novice or intermediate level skier. Advanced materials including lightweight metal alloys, carbon fiber composites, Kevlar, and even piezo-ceramics have been identified as performance enhancement factors. The author combines a science and engineering professional background with many years of ski instructing experience to review the contributions of materials in ski design and development.

Two models for the prior probability distribution are proposed: (1) the log-normal distribution, when there is some additional information to determine the scale of the true result, and (2) the 'alpha' distribution (a simplified variant of the gamma distribution) when there is not. These models have been incorporated into version 3 of the Bayesian internal dosimetry code in use at Los Alamos (downloadable from our web site). Plutonium internal dosimetry at Los Alamos is now being done using prior probability distribution parameters determined self-consistently from population averages of Los Alamos data.

We present new laboratory experimental evidence that low-frequency (100 Hz or less) stress waves could increase the mobility and transport of DNAPL by an order of magnitude or more during pump and treat. This unproven technology could decrease the time and cost of groundwater remediation efforts and reduce the final amount of contaminant trapped in an aquifer. A sand core was confined in a specialized flow apparatus and contaminated with a small amount of trichloroethylene (TCE). Steady-state water flow was then initiated through the core, and effluent TCE concentrations were measured using gas chromatography (GC). At various stages of water flow, axial stress cycling at 25-100 Hz was applied by mechanical coupling of a magnetostrictive actuator to the sand core's outlet face. During most of the stimulated runs pure-phase TCE droplets were produced in the effluent and the effective TCE concentration increased by as much as a factor of 20. Numerous flow runs were performed to investigate the effects of stimulation frequency, amplitude, and duration, as well as water flow rate and background effluent TCE concentration. Calibrated accelerometer and pore pressure measurements allowed determination of the stimulation threshold parameters required to achieve enhanced TCE production. The physical mechanisms responsible for the observed phenomenon are not fully understood. Further research is required before this promising new technology can be applied reliably to contaminated groundwater aquifers.

Waste types range from solvents, fuels, lubricants, and sludges to streams containing mixtures of these and other inorganic and organic compounds, along with potentially radioactive materials. Many of these compounds are amenable to treatment by electrochemical processes that destroy hazardous organic contaminants in aqueous streams at ambient temperatures and pressure. It is also possible to separate the radioactive components of these wastes from solution using electrochemical processes. In this article, we discuss the environmental factors and issues associated with electrochemical waste treatment processes. We summarize the federal regulations that compel government agencies to conduct environmental management activities. Applications of electrochemical processes to waste treatment and waste minimization at DOE and DOD sites are presented, and issues associated with acceptance of these processes are addressed.

Container materials and their welds will be exposed to ionizing radiation, elevated temperatures, embrittling and/or alloying agents (e.g., gallium and plutonium), chloride-containing compounds, and a limited quantity of moisture. All the above-listed environmental conditions have been shown to be deleterious to material integrity under certain conditions. Although the volume of the literature concerning failure of stainless steels is quite large, the interaction of the environment present within storage containers with stainless steels has not been comprehensively examined. This work attempts to detail selected relevant studies and assess the failure likelihood for storage of stabilized plutonium compounds.

We assessed the phylogenetic resolution and reproducibility of TRF profiles in order to evaluate the limitations of the method, and we developed an essential analysis technique to improve the interpretation of TRF data. The theoretical phylogenetic resolution of TRF profiles was determined based on the specificity of TRFs predicted from 3,908 16S rRNA gene sequences. With sequences from the Proteobacteria or gram-positive division, as much as 73% of the TRFs were phylogenetically specific (representing strains from at most two genera). However, the fraction decreased when sequences from the two divisions were combined. The data show that phylogenetic inference will be most effective if TRF profiles represent only a single bacterial division or smaller group. The analytical precision of the TRF method was assessed by comparing nine replicate profiles of a single soil DNA sample. Despite meticulous care in producing the replicates, numerous small, irreproducible peaks were observed. As many as 85% of the 169 distinct TRFs found among the profiles were irreproducible (i.e., not present in all nine replicates). Substantial variation also occurred in the height of synonymous peaks. To make comparisons of microbial communities more reliable, we developed an analytical procedure that reduces variation and extracts a reproducible subset of data from replicate TRF profiles. The procedure can also be used with other DNA fingerprinting techniques for microbial communities or microbial genomes.

We collected data on prey use and prey abundance three times a year during 2 y following the initial bobcat releases. We tested four hypotheses concerning bobcat prey selection: (1) use of a prey species was closely associated with its abundance (functional relationships), (2) the number of prey species included in bobcat diets increased as the abundance of principal prey species decreased (diet optimization), (3) the number of species included in bobcat diets and diet diversity increased as population density increased (interference) and (4) increases in the proportion of males resulted in increases in the use of large prey and decreases in the use of small prey. Bobcats' use of marsh rabbits (Sylvilagus palustris) and cotton rats (Sigmodon hispidus) was positively correlated with each species' abundance as predicted by a hypothesis of functional relationships. The number of prey species in bobcat diets and diet diversity was negatively correlated with the abundance of marsh rabbits as predicted by a hypothesis of diet optimization. Changes in diet diversity in different regions of the island between years were not correlated with changes in bobcat density within each region, suggesting interference was not occurring at the bobcat densities observed in our study. Changes in the use of Eastern grey squirrels (Sciurus carolinensis) between years were negatively correlated with increases in the proportions of male bobcats in different regions of the island. Our results suggest that diet optimization and functional responses are both useful models for describing bobcat-prey relationships. The diet optimization model had greater power to explain use of prey species that were not used in all seasons.

The experimental studies were designed to investigate the influence of EtOH addition, rate-limited mass transfer and subsurface layering on the micellar solubilization of PCE by aqueous solutions (4% wt.) of polyoxyethylene (20) sorbitan monooleate (Tween 80). In completely mixed batch reactors, the solubility of PCE in Tween 80 solutions (0.5 to 4% wt.) increased incrementally as the EtOH concentration was raised from 0% to 5% and 10%. Results of one-dimensional column studies demonstrated that solubilization of residual PCE was rate-limited regardless of the EtOH concentration. Effluent data were used to develop effective PCE mass transfer coefficients (K sub(e)) as a function of EtOH concentration, Darcy velocity, and duration of flow interruption. For the heterogeneous 2-D system, solutions containing 4% Tween 80 or 4% Tween 80 + 5% EtOH were injected into rectangular boxes packed with 20-30 mesh Ottawa sand and three low permeability layers. Visual observation of surfactant fronts and effluent concentration data demonstrated that the addition of 5% EtOH resulted in density over ride of the injected solution, and failed to enhance PCE recovery compared to the 4% Tween 80 solution alone. The results of this work indicate that although relatively small additions of EtOH can improve the solubilization capacity of surfactant formulations, differences between flushing and resident solution density must be carefully accounted for when utilizing cosolvent-amended surfactant formulations for DNAPL remediation.

N1 - Last updated - 2011-10-26 ER - TY - JOUR T1 - Quantitative measurements of airflow inside a nuclear laboratory. AN - 85259614; pmid-11089809 AB - Dispersion dynamics of accidentally released radioactive aerosols or gases through laboratory workrooms are determined primarily by airflow, which impacts the level of human exposure and the response of air monitoring instrumentation. Therefore, applying conclusions derived from measurements of the fundamental aspects of airflow (velocity, direction, and turbulence) can lead to better protection of workers by suggesting appropriate locations for air monitoring and sampling. Historically, it has been very difficult to quantitatively measure these fundamental aspects of indoor airflow because of the low flow rates (often <10 cm s(-1)) and difficulties in quantitative measurement of three-dimensional airflow. Recent advances in sonic anemometry have enabled such measurements. For this study, a sonic anemometer was used that was capable of measuring airflow velocities with a sensitivity of about 0.5 cm s(-1) for each of the three-directional components. A sampling frequency of 1 Hz was selected to measure the fluctuations in the air velocity associated with turbulence and expressed in terms of "turbulence intensity." Point measurements of airflow velocities, directions, and turbulence intensities were made at 69 locations in a mechanically ventilated plutonium laboratory located at Los Alamos National Laboratory. Although the measurements were not made with workers present, all measurements were made at a height of 1.5 m, approximately the height of a worker's breathing zone (BZ). Velocities ranged from 8 cm s(-1) to 41 cm s(-1), with a median velocity of 18 cm s(-1). Percent turbulence intensities ranged from 13% to 57% with a median of 34%. The measured velocities and turbulence intensities in the laboratory showed that forced convective flows and turbulent eddy diffusion drive dispersion of released aerosols or gases. Results show that after an airborne release, mixing within the room can take minutes and may not always be complete. This is contrary to simplifying assumptions made by some risk modeling of accidentally released materials in a room. Our results also suggest that the mixing pattern would not be omnidirectional at most release locations, especially in the early stages of the release. Finally, airflow directions were upwards in breathing zones at most workstations. Because most releases in the plutonium laboratory occur at a height immediately below the BZ, the concentrated aerosol could be lifted into the BZ, followed by dispersal to the air monitor with the initiation of alarm.

Application of a modified dynamic melting inversion (DMI) method presented here to SE China basalts suggests that Nushan and Fangshan basalts are formed by 4-11% partial melting of a light-rare-earth-element-enriched mantle source. The negative correlation between (super 143) Nd/ (super 144) Nd and (super 206) Pb/ (super 204) Pb and the positive relationship between (super 87) Sr/ (super 86) Sr and (super 206) Pb/ (super 204) Pb strongly suggest a mixing of an intermediate-depleted asthenospheric mantle source and an EM2 component in the study area. The occurrence of the EM2 signature and the diminishing of this signature from south to north in the study area are consistent with the hypotheses that SE China was a part of Gondwanaland. In addition, isotopic constraints from SE China basalts are consistent with the crustal detachment model of Li [Li, Z. X., 1994. Collision between the North and South China blocks: a crustal-detachment model for suturing in the region east of the Tanlu fault. Geology, 22, 739-742] that a subsurface suture between South China and North China Blocks runs eastward through Nanjing. When published isotopic data for Cenozoic basalts from NE China are included, basalts in the whole of eastern China have high (super 208) Pb/ (super 204) Pb and (super 207) Pb/ (super 204) Pb at a given (super 206) Pb/ (super 204) Pb, a feature that is commonly observed in the Southern Hemisphere Dupal oceanic island basalts. In addition, (super 206) Pb/ (super 204) Pb decreases from south to north. Such a regional variation of Pb isotopic compositions in the whole of eastern China cannot simply be attributed to mixing of two mantle endmembers because Nd and Sr isotopic compositions show opposite regional variations in SE China and NE China. The SE China basalts suggest mixing between an asthenospheric mantle and EM2, while the NE China basalts reflect mixing between an asthenospheric mantle and EM1. The central-eastern China basalts from Nushan, Fangshan, and Tashan have the most depleted Nd and Sr isotopic compositions that may represent the isotopic composition of the asthenospheric mantle. The occurrence of Pb-Dupal signatures in these central-eastern China basalts may imply that the asthenospheric mantle already had a Pb-Dupal signature before its mixing with EM1 or EM2.

Although superficially these deposits resemble typical facies from Strombolian eruptions (emplaced ballistically, by fallout, and by rolling and local grain-avalanches down steep cone slopes), there are several lines of evidence that lead to an interpretation that the deposits were emplaced by pyroclastic density currents. These include local coarse-tail grading, deformation of spatter clasts in a down-flow direction, incorporation of matrix ash and lapilli into flattened spatter clasts, imbrication of large clasts, plastering of spatter on stoss sides of large lithic blocks and lenses of lithic-rich material on lee sides, deposition on angles less than the angle of repose, and a paucity of clast shapes associated with Strombolian mechanisms. The deposit characteristics are consistent with rapid sedimentation from a low-particle-concentration, turbulent flow onto an aggrading bed. We infer two potential mechanisms for generating these density currents: (1) explosive magma-water interaction involving lithic debris and relatively unfragmented melt; and (2) collapse of oversteepened upper cone slopes due to rapid accumulation of spatter from voluminous Strombolian eruptions.

The electrical conductivity of the Earth's mantle is influenced by many factors, which include temperature, pressure, the coexistence of multiple mineral phases, and oxygen fugacity. In order to treat these factors and to estimate the resulting uncertainties, we have used a variety of spatial averaging schemes for mixtures of the mantle minerals and have incorporated effects of oxygen fugacity. In addition, to better calculate lower mantle conductivities, we report new measurements for electrical conductivity of magnesiowuestite (Mg (sub 0.89) Fe (sub 0.11) )O. Because the effective medium theory averages lie between the Hashin-Shtrikman bounds for the whole mantle, a laboratory-based conductivity-depth profile was constructed using this averaging scheme. Comparison of apparent resistivities calculated from the laboratory-based conductivity profile with those from field geophysical models shows that the two approaches agree well.

Two tuff cores were studied, one with a matrix porosity of 0.27 and the other with a porosity of 0.14. The matrix permeabilities of the cores were 4.7 X 10 (super -15) and 7.8 X 10 (super -19) m (super 2) , 5 and 9 orders of magnitude less than the respective fracture permeabilities. This suggested that the cores could be modeled as dual-porosity systems with no flow in the matrix but significant solute storage capacity. Two types of tracer tests were conducted in each fractured core: (1) iodide was injected in separate experiments at different flow rates and (2) two tracers of different matrix diffusion coefficients (bromide and pentafluorobenzoate (PFBA)) were injected in another test. A difference in the maximum concentrations of the solutes and the extended tailing of the breakthrough curves were assumed to be indicative of diffusive mass transfer between the fracture and the porous matrix of the cores. Interpreting the results from both methods allowed the identification of matrix diffusion and dispersion effects within the fracture by simultaneously fitting the data sets (with known constraints) using a relatively simple conceptual model. Estimates of mass transfer coefficients for the fractured cores were also obtained. Copyright 2000 by the American Geophysical Union.

We used four distinct methods to investigate the broadband source process and thereby better understand the tectonic implications of this event. We relocated aftershocks using a master event technique and found that the distribution of aftershocks covers a region of 200 km in lateral extent. We also employed a surface wave spectral inversion technique to estimate the mainshock moment, depth, centroid location, and centroid time and utilized an empirical Green's function technique to extract rupture directivity information and a detailed source time function from observed seismograms. We also inverted body waves to estimate the moment release along the fault and the source time function. The 1997 earthquake ruptured a strike-slip fault that appears to be an extension or splay of the Kun Lun fault system. This fault is one of the most seismically active strike-slip faults within the Tibetan plateau and has had events with surface wave magnitudes of 6.1, 7.4, and 7.9 in this region since 1973. The rupture released most of the energy within the first 20 s and propagated bilaterally initially, with the later rupture propagating westward for 20-30 s. The absence of large aftershocks suggests that the earthquake efficiently released the stored strain. Comparing mainshock to the largest aftershock energy ratios for this event and other large strike-slip events shows that faulting within the plateau has the characteristics of weak faults (e.g., fracture zone faulting).

The effects of joints on propagation of small amplitude stress waves (seismic waves) have been reported. There is extensive literature on how blocks move past each other in low strain-rate deformation. How joints alter blast effects has also been addressed both numerically and experimentally. But real joints will rarely be empty. Therefore, practical applications of blasts, such as the use of explosive charges for construction or extraction, must consider the effect of joints on the propagation and effectiveness of shock waves. The little data that have been reported on the effects of filled joints relate to seismic or low strain-rate deformation or the interrelationships among the seismic, mechanical and hydraulic properties.

Mechanisms governing surface water vapor variability during SALSA AN - 17903534; 5175985 AB - An integrated tool that consists of a volume scanning high-resolution Raman water vapor LIDAR and a turbulence-resolving hydrodynamic model, called HIGRAD, is used to support the semi-arid land-surface-atmosphere (SALSA) program. The water vapor measurements collected during SALSA have been simulated by the HIGRAD code with a resolution comparable with that of the LIDAR data. The LIDAR provides the required "ground truth" of coherent water vapor eddies and the model allows for interpretation of the underlying physics of such measurements and characterizes the relationships between surface conditions, boundary layer dynamics, and measured quantities. The model results compare well with the measurements, including the overall structure and evolution of water vapor plumes, the contrast of plume variabilities over the cottonwoods and the grass land, and the mid-day suppression of turbulent activities over the canopy. The current study demonstrates an example that such an integration between modeling and LIDAR measurements can advance our understanding of the structure of fine-scale turbulent motions that govern evaporative exchange above a heterogeneous surface.

AN - 72423941; 11085392 AB - The extreme variability of human immunodeficiency virus type 1 (HIV-1) makes it possible to conduct transmission studies on the basis of genetic analysis and to trace global and local patterns in the spread of the virus. Two such patterns are discussed in this paper. First, in many European countries (e.g., Scotland and Germany), homosexual men tend to be infected with a subtly different variant of HIV-1 than intravenous drug users. In other European countries (e.g., Norway and Sweden), a distinction is also found between the two risk groups; but based on available data, the distinction is a different one. The second pattern is a worldwide tendency for homosexual men in many different geographic regions around the world to carry HIV-1 subtype B, the variant that is most prevalent in the Americas, Europe, and Australia. In contrast, people infected via other routes (mostly heterosexual contact) in those same countries carry a mixture of other subtypes. Biologic differences between the viruses infecting different risk groups have not been found; the most likely explanation for the findings is different epidemiologic patterns. Although data are still scarce, the authors attempt to use these patterns in the reconstruction of the worldwide spread of the HIV epidemic.

The samples were analyzed for 3 H, 238 Pu, 239, 240 Pu, 90 Sr, 241 Am, 137 Cs, and tot U, and 12 of the soil samples were analyzed for gross alpha, beta, and gamma radioactivity. Tritium, 238 Pu, 239,240 Pu, and 241 Am concentrations in soils were above the upper 95% level of background concentrations; all, however, were less than LANL screening action levels. In contrast, most of the radionuclide concentrations in the unwashed vegetation samples were below the upper 95% level of background concentrations, except for 3 H. Tritium concentrations in vegetation from most sites were greater than background concentrations of about 2 pCi mL-1.

Detailed process-based models rather than higher-level performance-assessment models are used to perform the transport calculations. The deterministic analyses predict the fate of the waste from its source, through the vadose zone, into the saturated zone and, finally, the potential dose to humans at the accessible environment. The calculations are run with the finite-element code FEHM, which simulates fluid flow, heat transport, and reactive, contaminant transport through porous and fractured media. The modeling approach for this study couples realistic source-term models with an unsaturated-zone flow and transport model, which is then linked to the saturated-zone flow and transport model. The three-dimensional unsaturated-zone flow and transport model describes the complex hydrology associated with the mesa-top and volcanic geology of the site. The continued migration of nuclides into the main aquifer is calculated using a three-dimensional, steady-flow, saturated-zone model that maintains the spatial and temporal distribution of nuclide flux from the vadose zone. Preliminary results for the aquifer-related dose assessments show that doses are well below relevant performance objectives for low-level waste sites. A general screening technique that compares the nuclide's half-life to its unsaturated-zone travel time is described. This technique helps to decrease the number of transport calculations required at a site. In this case, over half the nuclides were eliminated from further consideration through this screening.

AN - 85356374; pmid-11051479 AB - Condensation may occur in an open-flow thermoacoustic cooler with stack temperatures below the saturation temperature of the flowing gas. In the experimental device described here the flowing gas, which is also the acoustic medium, is humid air, so the device acts as a flow-through dehumidifier. The humid air stream flows through an acoustic resonator. Sound energy generated by electrodynamic drivers produces a high-amplitude standing wave inside of the resonator, which causes cooling on a thermoacoustic stack. Condensation of water occurs as the humid air passes through the stack and is cooled below its dew point, with the condensate appearing on the walls of the stack. The dry, cool air passes out of the resonator, while the condensate is wicked away from the end of the stack. Thermoacoustic heat pumping is strongly affected by the form of the condensate inside of the stack, whether condensed mostly on the stack plates, or largely in the form of droplets in the gas stream. Two simple models of the effect of the condensate are matched to a measured stack temperature profile; the results suggest that the thermoacoustic effect of droplets inside the stack is small.

The fundamental characteristics of radiogenic isotope ratios in chemically evolving waters make them highly effective as preferential flow path indicators. These ratios tend to be more easily interpreted than solute-concentration data because their response to water-rock interaction is less complex. We demonstrate this approach with groundwater (super 87) Sr/ (super 86) Sr ratios in the Snake River Plain aquifer within and near the Idaho National Engineering and Environmental Laboratory. These data reveal slow-flow zones as lower (super 87) Sr/ (super 86) Sr areas created by prolonged interaction with the host basalts and a relatively fast flowing zone as a high (super 87) Sr/ (super 86) Sr area.

The discovery shows that iron ooid formation is geologically a rapid process. The ooids form by chemical precipitation of cryptocrystalline iron oxyhydroxides on available grains on the seafloor, from seawater enriched with Fe, Al and Si. The enrichment can be a result of hydrothermal fluids, volcanic ash falls into shallow basins or rapid weathering of fresh volcanic rocks. Ordovician iron ooids from northern Europe are strikingly similar to the modern ooids in chemical composition, REE distributions and internal structures. The differences in mineralogy can be explained as diagenetic transformation reactions under different environments. A model for the formation of the Ordovician iron ooids in northern Europe from volcaniclastic material is presented, which could be applicable to other ancient oolites in the world.

Foraminifera Globigerinoides spp., Globigerina bulloides and Uvigerina, from near-surface, intermediate and bottom water layers, respectively, were studied in two drillcores from SW Poland. Differences in T between surface and bottom waters during evaporite deposition produce different delta (super 18) O and delta (super 13) C values for these taxa. Changes in foraminifera assemblages are interpreted to show different, and rapidly changing, environmental conditions. Comparison with well-recognized assemblages allows determination of the biostratigraphy of middle Miocene deposits in the central para-Tethys.

Uranium uptake was estimated in tomato (Lycopersicon esculentum), squash (Cucurbita pepo), lettuce (Lactuca scarriola), and radish (Raphanus sativus) irrigated with Nambe well water containing less than 1, 150, 500, and 1200 micrograms U L-1. Plant uptake and human dose and toxicity associated with ingestion of water and produce and inhalation of irrigated soil related to gardening activities were evaluated. Uranium concentration in plants increased linearly with increasing U concentration in irrigation water, particularly in lettuce and radish. The estimated total committed effective dose equivalent for 70 years of maximum continuous exposure, via the three pathways to well water containing 1200 mg U L-1 , was 0.17 mSv (17 mrem) with a corresponding kidney concentration of 0.8 mg U g-1 kidney.

Our purpose is to create high resolution path correction maps for use in regional distance source discrimination and magnitude determination, as well as to study L (sub g) propagation characteristics in one of the most heterogeneous portions of the earth. For 1.0 Hz data, tomography reduced variance 33%, relative to a best fit, uniform Q model. L (sub g) Q varied with geologic region, with low values in Tibet, the Tien Shan and the Pamir range (Q = 200 to 400), intermediate values in basins such as the Tarim (Q = 500) and high values for platforms and older crust (Q > 800). The relatively efficient propagation across the Tarim differs from the poor propagation that is generally observed across sedimentary basins. Copyright 2000 by the American Geophysical Union.

In contrast to facultative anaerobic environments, where dissimilatory iron-reducing bacteria (DIRB) are often abundant, few studies have detailed microbial interactions with Fe(III) (hydr)oxides in aerobic environments. To better understand acquisition of Fe from Fe(III) (hydr)oxides, we investigated the production of siderophore and Fe(III) reduction by a strict aerobe in the presence of synthetic hematite as a source of Fe. Pseudomonas mendocina grew best when Fewas supplied as FeEDTA (~1.8x10 super(8) colony-forming units [CFU] ml super(-1)), grew abundantly when Fe was supplied as hematite (~1.2x10 super(8) CFU ml super(-1)), and grew poorly when Fe was withheld from the medium (~5.5x10 super(7) CFU ml super(-1)). As expected, negligible siderophore was produced per cell when Fe was supplied as FeEDTA and more siderophore was produced in the hematite flasks than in the controls. Thus, growth of P. mendocina and the production of siderophore in the presence of hematite present compelling evidence that siderophore was produced as a mechanism to acquire Fe from hematite. For the Fe reduction experiments, Fe reduction by components of the supernatant fluid was induced weakly when Fe was supplied as hematite or as FeEDTA, but much more when the cells were cultured under extreme Fe deprivation. In fact, 16 times as much Fe reduction occurred in the controls as in the presence of either of the FeEDTA or hematite amendments. Our results, which contravene the long-held assumptions that Fe acquisition was facilitated solely by siderophores, provides a new perspective regarding microbial interactions with Fe bearing minerals.

It is known for its rich Acheulean archeological occurrences and abundant vertebrate fossils, including those of A. boisei and H. erectus. The formation also contains more than 30 tephra layers. The lithologic characterization and major element compositions of discrete glass shards of these tephra, combined with single-crystal (super 40) Ar/ (super 39) Ar dating of seven tuffs, have established the tephrostratigraphy and age range of the 200-m thick formation. The succession at Konso was deposited between approximately 1.9 and 1.4 Ma and is divided into the Sorobo, Turoha, Kayle, and Karat Members in ascending stratigraphic order. Two of the Konso tephra are correlative to the Pliocene KBS and the early Pleistocene Chari Tuffs of the Omo-Turkana Basin along the Ethiopian and Kenyan border. This correlation enables precise time-controlled comparisons of faunal and archeological remains between the two regions.

SAGE was conceived from a vision that something special would come from pooling the resources and talents of diverse groups. It enables undergraduate and graduate students from large and small schools alike to share the excitement of hands-on, modern field geophysical research and learning. Much more than a summer geophysics field camp, SAGE is an immersion in geophysics, an educational experience that many students say is the most satisfying in their lives. Students participate in every phase of the field program: They collect data with modern equipment; they process, model, and interpret the data with workstations and PCs; and they present their results in both oral and written form. The program is not just about using equipment; it's about understanding what the equipment is measuring and how to make sense of it.

While one of the main advantages of minipermeameters is their ability to collect data on various support volumes, there have been only limited attempts to analyze their size and geometry. We define the support volume of minipermeameter measurements as a region containing 90% of the total gas flow, i.e., a region bounded by the 10% streamline. Using our new semianalytical solutions for the Stokes' stream function, we demonstrate that the support volume has a shape of the semitoroid adjacent to the sample surface. Hence there is a blind spot directly below the minipermeameter, which is not probed by the measurement. We demonstrate that the support volume of the minipermeameter measurements decreases with the tip-seal's ratio (a ratio of the inner tip-seal radius to the outer tip-seal radius), while the size of the corresponding blind spot increases.

In the paper, we will discuss neutron and X-ray reflectometry and grazing incidence X-ray diffraction techniques used to explore structures of such ultra-thin organic films in different environments. We will illustrate the use of these methods to characterize the morphologies of the following systems: (i) polyethylene glycol-modified distearoylphosphatidylethanolamine monolayers at air-liquid and solid-liquid interfaces; and (ii) assemblies of branched polyethyleneimine polymer and dimyristoylphophatidylcholine lipid at solid-liquid interfaces.

AN - 71761736; 10933853 AB - Microsphere-based flow cytometric detection of cholera toxin (CT) through distance-dependent fluorescence resonant energy transfer (FRET) has been developed. Simultaneous double-fluorescence changes induced by multivalent interactions between CT and fluorophore (both fluorescence donor and acceptor)-labeled ganglioside GM1 on a biomimetic membrane surface (supported bilayers of phospholipids) can be measured by a commercial flow cytometer, providing a convenient and sensitive detection method for CT. The flow cytometry-based biosensor is capable of detecting less than 10 pM CT within 30 min. The signal generation strategy coupled with flow cytometry also provides a convenient method for kinetic studies of multivalent interactions. The surface density and the ratio of donor/acceptor-labeled GM1 on the surfaces of phospholipid bilayers are optimized to achieve high sensitivity.

Here we provide an independent way of estimating the maximum degree of contamination by sediment using constraints from (super 10) Be. Since (super 10) Be is mostly a cosmogenic nuclide and has a half life of 1.5X10 (super 6) years, any (super 10) Be found in a MORB glass must result from contamination by sedimentary material where cosmogenic (super 10) Be is enriched. Four MORB samples with a wide range in Th concentrations (87-550 ppb) were measured for U decay series and (super 10) Be. No (super 10) Be above the detection limit (6X10 (super 4) to 1X10 (super 5) atoms) was measured in the glasses except for one sample that was not picked. Considering that the sedimentary contaminant contains 10 (super 9) to 10 (super 10) atoms/g, the maximum fraction of contaminant in the picked glasses is 10 (super -4) to 10 (super -5) . Mass balance calculations between a surficial contaminant and a hypothetical pristine glass with ( (super 231) Pa/ (super 235) U) = 1 and ( (super 10) Be/ (super 9) Be) = 0 show that only for the unpicked sample, nearly all the measured excess (super 231) Pa can be accounted for by contamination. For the other samples, <15% to <1% of the excess (super 231) Pa and (super 230) Th can be explained by incorporation of sedimentary material. This study reemphasizes the need for careful sample preparation for U series measurements in MORB, especially at low U levels (<50 ppb). It also confirms that the large U series excesses in carefully picked and cleaned MORB samples are magmatic in origin.

On-line monitoring of process and wastewater streams optimizes the control of treatment methods by providing early indications of problems that could increase discharges of hazardous compounds to the environment. It is important for the immediate detection and remediation of process upsets in critical streams. The waste flow to the Radioactive Liquid Waste Treatment Facility at the Los Alamos National Laboratory (LANL) is processed before discharge and requires monitoring. Process chromatography is used to monitor the trends of contaminants in real time. The purpose of this study is to develop an automated on-line IC procedure for the simultaneous determination of anions in LANL wastewater.

Colloid presence and their potential mobility are justified on the basis of colloid stability properties in the investigated groundwaters. The colloid concentration is a function of pH, redox potential, concentrations of Na, K, Ca, Mg and organic carbon, as well as the status of the chemical and physical steady state of the hydrogeochemical system. The colloid properties are discussed with a non-site specific approach.

Three samples were collected across-axis on the Axial Volcanic Ridge (i.e. the Neovolcanic Ridge) near the Snake Pit hydrothermal mound, and one sample was collected near the crest of Serocki Volcano approximately 50 km south of Snake Pit. ( (super 226) Ra)/( (super 230) Th) and ( (super 230) Th)/( (super 238) U) activity ratios are low and uniform for all four samples, while ( (super 231) Pa)/( (super 235) U) activity ratios are elevated and somewhat more variable. Age constraints suggest that these lavas, from the most robust volcanic edifices in the MARK area, are 10000-20000 yr old. The age data are used to evaluate the efficacy of commonly used age estimate scales based on qualitative indicators (e.g. sediment cover, glass quality) and to begin to quantify the temporal and spatial dependence of volcanic, tectonic and hydrothermal processes at slow-spreading oceanic ridges.

Based on the delta D and delta (super 18) O contents of the fumarole condensates, all fumaroles sampled after 1980 discharge a mixture of magmatic and meteoric fluids. By 1994, the apparent end-member exsolved magmatic water delta D content had been depleted by nearly equal 7 per mil relative to the original 1980 composition indicating that an appreciable amount of the water had yet to degas from the melt. However, Cl and F contents in the samples collected in 1994 were only 0.47% and 3.8%, respectively, of the concentrations measured in fumarole condensates representative of degassed end-member magmatic water in 1980. Based on delta D modeling, approximately 63% of shallow Mount St. Helens magma had yet to degas by 1994 indicating that most Cl was emitted to the shallower levels very early in the degassing history. By 1994, any emitted Cl was not reaching the shallower levels of the volcano. Because metals can be transported as Cl complexes, this change in behavior could have implications for the timing and location of metal transport and deposition.

The observed long duration of S waves has been explained as being caused by multiple forward scattering around the ray path between source and receiver. Array observations of Lg waveforms have also shown that multiple forward scattering along the path between the source and receiver are important influences on the character of Lg waveforms and that the scattering cannot be explained only by vertical variations in velocity. Multiple forward scattering in 3D has been modeled using the Markov approximation for the parabolic-wave equation, which allows the calculation of seismogram envelopes in statistically characterized random media. To test the range of validity of the Markov approximation-derived solutions, we made 2D numerical calculations of wavefields in random media using approximations to the parabolic wave equation, which only models forward scattering, and by finite-difference solution of the scalar-wave equation, which gives complete wavefields. Media of background velocity 4 km/sec are characterized using a Gaussian autocorrelation function with a 5 km correlation distance and 5% rms fractional fluctuation. To compare with envelopes obtained from the Markov approximation, we calculated wavefields for source-receiver distances ranging from 50 to 200 km for several statistically identical realizations of random media. We obtain ensemble average envelopes by averaging envelopes from the realizations. We find a good agreement between ensemble-average envelopes obtained from the numerical solution of the parabolic-wave equation and envelopes obtained from the Markov approximation. The later portion of the ensemble-average envelopes calculated using finite difference have larger amplitudes than those from the Markov approximation, which is probably due to the late-arriving energy that has been scattered at wide angles from the global propagation direction between the source and the receiver. We observe that the variations among the numerically calculated envelopes of individual realizations of random media are well fit by a Rayleigh distribution, which describes the distribution of envelope amplitude when signals of one frequency but random phase are summed. Our results show that the Markov approximation provides reliable information about envelope shapes for forward-scattered wavefields but that the influence of wide-angle scattering and backscattering have some influences on envelope shapes and should be considered when analyzing data using random media models.

Understanding trace-element mineralogic speciation in the environment is crucial to proposing natural attenuation as a remedial action at such sites. Barium nitrate was a component of explosives that were processed at LANL's Technical Area 16 during the Manhattan Project. Soils, sediments, and alluvial waters at Technical Area 16 are highly contaminated with barium. Soil concentrations range to 40 000 ppm and water concentrations range to 10 mg/L. SEM investigations of barium-contaminated soils and sediments reveal that barium occurs in three mineralogic forms and sorbed on soil particles. Barite is widespread in alluvial sediments. It occurs as overgrowths on quartz grains, on organic particles, and as small (less than 50 micron) isolated grains. Witherite is found in overbank sediments and within barium-contaminated landfills. Witherite particles are typically large (up to 100 micron) grains with pronounced dissolution textures. A barium silicate occurs as overgrowths on magnetite and steel within barium-contaminated landfills. Thermodynamic calculations show that alluvial and spring waters are oversaturated with barite at 0 to approximately 7.5 pH. Witherite is oversaturated at pH greater than approximately 8.8. Barite is confined to the flowing stream channel because sulfate is abundant there (greater than 10 mg/L). Witherite is precipitated due to evaporation of low-sulfate rainwaters in the presence of high- barium sediments. These calculations, which suggest that barium is being sequestered as insoluble barite in the alluvial system, may be used to support monitored natural attenuation as a remedy for barium contamination.

Thus new approaches to the long-term planning and problem solution in the field of RW and SNF management should be elaborated. In this context, radionuclide transport peculiarities in different geological conditions have to be investigated. The main aim of our investigation is to analyse the separate radionuclides and sites, and to develop comparable transport codes as well as to evaluate and harmonize the proper performance assessment approaches. During the progress of comparative studies the following underground research centers and potential repository sites have been considered:- Salt formations: WIPP(USA), Gorleben site (Germany), sites in Russia (Baltic, Volgograd, and Tula regions); - Basalts: Mayak site (Russia), Hanford site (USA); - Granite and granito-gneiss: Grimsel Test Site (Switzerland), Aspo Hard Rock Lab (Sweden), Tono-Kamaishi sites (Japan), Research Tunnel Olkiluoto (Finland), AECL (Canada), Kola Peninsula and Krasnoyarsk sites (Russia); - Welded tuffs and ignimbrites: Yucca Mountain (USA). Some preliminary results from consideration are discussed and is shown the necessity of more close international co-operation for harmonization of practices and standards for solving the mentioned problems.

Scanning electron microscopy, transmission electron microscopy, molecular biology techniques, enrichment cultures, bulk chemistry, and X-ray diffraction techniques have revealed the presence of iron- and manganese-oxidizing bacteria in corrosion residues, which supports the hypothesis that these organisms utilize reduced iron and manganese from the limestone, leaving behind oxidized iron and manganese. Metabolically active populations of bacteria are also found in "punk rock" beneath the corrosion residues. Microscopic examination of pool fingers demonstrates that microorganisms can be inadvertently caught and buried in pool fingers, or can be more active participants in their formation. Enrichment cultures of moonmilk demonstrate the presence of a variety of microorganisms. Humans can have a deleterious impact on microbial communities in Guadalupe caves.

Subsequent exploration and research have demonstrated that Lechuguilla is a world-class cave, both in size and in speleological importance. Of particular interest to hydrologists and geochemists are the numerous isolated pools throughout much of the cave. Since 1986, close to 200 water samples have been collected and subjected to over 2000 individual analyses. Results of these analyses are collected and published here for the first time. Dominant cations in the pool waters are calcium and magnesium; dominant anions are bicarbonate and sulfate. These characteristics reflect the limestone/dolomite host bedrock of the cave, modified to varying degrees by the cave's massive gypsum deposits, associated with the cave's early development. The overall chemistry of the water can be explained by a small number of geochemical processes, starting with evaporation and concentration of local rainfall, and dissolution of soil CO (sub 2) and local bedrock. Within the cave, excess CO (sub 2) is degassed, leading to precipitation of CaCO (sub 3) and increased Mg (super 2+) :Ca (super 2+) ratios. In some areas of the cave, infiltrating water encounters and dissolves gypsum, leading to increased CaCO (sub 3) precipitation and increased SO (sub 4) (super 2-) :HCO (sub 3) (super -) ratios. In at least one location, massive evaporation has created a magnesium sulfate brine. Geochemical characteristics seem to confirm that the pool located at Lechuguilla's current deep point is actually the regional aquifer, suggesting that the cave's maximum air-filled depth has been reached.

These results afford improved surface resolution and detailed views of the potassium, rare earth elements, and phosphorus (KREEP) distribution within and around Mare Imbrium and elsewhere. The Gd and Sm results serve as a complementary and independent check of the distribution of KREEP on the Moon, in contrast with the Lunar Prospector gamma ray spectrometer results for thorium. The neutron spectrometer observations reflect the presence of Fe and Ti as well as Gd and Sm. The contributions of Fe and Ti are removed using high spatial resolution Clementine spectral reflectance determinations of FeO and TiO (sub 2) abundances. Overall, the resulting Gd and Sm abundance map agrees with the Th abundance map determined using the Lunar Prospector gamma ray spectrometer. In general, the detailed features of the Procellarum/Imbrium KREEP terrane are found in both. For example, distinct highs in Gd, Sm, and Th abundances are resolved over the craters Mairan, Aristarchus, Kepler, Reinhold, Lalande, and Aristillus, over the Apennine Bench and Fra Mauro regions, and over the Montes Jura and Montes Carpatus, indicating an enhanced abundance of KREEP in these locations. The neutron observations also provide constraints on FeO and TiO (sub 2) abundances; for some high-Ti locales, there is a significant disagreement with TiO (sub 2) abundances inferred from Clementine spectral reflectance.

An analysis of the uncertainties shows that the measured uncertainties are 7 mu g/g are likely small area regions < (150 km) (super 2) . Using lunar topographic data, we have shown that the thorium abundances in the lunar high-lands and portions of South Pole-Aitken (SPA) Basin are larger for lower elevations. We have also studied a number of regions with anomalously high thorium abundances such as the northwestern region of SPA Basin, the crater Arago in western Tranquillitatis, and the Compton/Belkovich region in the northeastern highlands. The Compton/Belkovich region appears to be enriched with evolved rocks such as alkali anorthosite and currently represents the only such extended region on the Moon that has been identified. In contrast, Tycho crater has very low thorium abundances which suggests that KREEP was not assimilated at depth in this portion of the Moon. Copyright 2000 by the American Geophysical Union.

The period of data collection extends from January 1998 to July 1999; the spacecraft altitude varied between 15 km and 140 km. Maps are at a 2 degrees X2 degrees equal-area resolution. They show high counts and high variability for the mare and, low counts and low variability for the highlands. Such variability is due to differences of Fe and Ti concentrations in the lunar regolith, plus other elements with lesser effect that have not yet been included in our calculations. Assuming that only FeO and TiO (sub 2) concentrations are responsible for the fast neutron structures, fluxes are 2.7 times more sensitive to FeO than to TiO (sub 2) . The statistical resolutions are 1.3% in FeO and 3.5% in TiO (sub 2) . No discrimination of FeO is possible below 6.5%. Results are supported by numerical simulations. We also present the first lunar neutron spectrum over 16 channels between 0.6 and 8 MeV. Ninety-five percent of the counts are below approximately 4.5 MeV. In flux units the spectrum peaks at approximately 1.5 MeV. Its shape agrees with numerical simulations. Copyright 2000 by the American Geophysical Union.

Most of this information resides in a single parameter, the ratio of macroscopic absorption to energy-loss cross sections. Although this parameter cannot specify the chemistry of lunar soils uniquely, it provides an index that can be used to quantitatively separate anorthositic from mafic chemistries. Hydrogen abundances can best be derived from measurements of the epithermal neutron flux, which is strongly related to its macroscopic energy-loss cross section. The ratio of thermal to epithermal neutron flux measured by Lunar Prospector is shown to agree quantitatively with simulations. This agreement is used to show that the highlands terrane on the farside of the Moon is anorthositic, containing high percentages of plagioclase and possibly a range of Mg-suite minerals with a high Mg/(Mg + Fe) atomic ratio. Our best estimate of the abundance of FeO is 2%, with an upper limit of 5%. Copyright 2000 by the American Geophysical Union.

Intriguing distributions can, however, arise merely by chance, and it often proves difficult to know whether a seemingly interesting pattern is truly significant. This problem has particularly troubled students of island biogeography, who for the past quarter century have debated the right way to evaluate the distribution of species on island archipelagos. The solution described here invokes a simple algorithm used to compute the "knight's tour," an exercise that has long been taught to undergraduates in computer science. The article illustrates the newly developed method for testing the significance of ecological patterns by applying it to Darwin's finches on the Galapagos Islands.

The flow nonstationarity may stem from medium nonstationarity (e.g., the presence of distinct geological layers, zones, or facies), finite domain boundaries, and/or fluid pumping and injecting. This work provides an approach for studying solute transport in multiscale media, where random heterogeneities exist at some small scale while deterministic geological structures and patterns can be prescribed at some larger scale. In such a flow field the solute flux depends on solute travel time and transverse displacement at a fixed control plane. The solute flux statistics (mean and variance) are derived using the Lagrangian framework and are expressed in terms of the probability density functions (PDFs) of the particle travel time and transverse displacement. These PDFs are given with the statistical moments derived based on nonstationary Eulerian velocity moments. The general approach is illustrated with some examples of conservative and reactive solute transport in stationary and nonstationary flow fields. It is found based on these examples that medium nonstationarities (or multiscale structures and heterogeneities) have a strong impact on predicting solute flux across a control plane and on the corresponding prediction uncertainty. In particular, the behavior of solute flux moments strongly depends on the configuration of nonstationary medium features and the source dimension and location. The developed nonstationary approach may result in non-Gaussian (multiple modal) yet realistic behaviors for solute flux moments in the presence of flow nonstationarities, while these non-Gaussian behaviors may not be reproduced with a traditional stationary approach.

This paper describes the application of the Bayesian approach to predict the location of plastic hinge deformation using the experimental data obtained from the vibration tests of a reinforced-concrete bridge column. The column was statically pushed incrementally with lateral displacements until a plastic hinge is fully formed at the bottom portion of the column. Vibration tests were performed at different damage stages. The proposed damage detection method was able to locate the damaged region using a simplified analytical model and the modal parameters estimated from the vibration tests, although (1) only the first bending and first torsional modes were estimated from the experimental test data, (2) the locations where the accelerations were measured did not coincide with the degrees of freedom of the analytical model, and (3) there existed discrepancies between the undamaged test structure and the analytical model. The Bayesian framework was able to systematically update the damage probabilities when new test data became available. Better diagnosis was obtained by employing multiple data sets than just by using each test data set separately.

The noticeable presence of pocket gopher mounds and cast soil on closed waste burial sites of various types resulted in the need to understand possible interactions between gophers and radioactive waste at Area G. In our study, pocket gophers, mound soil, off-mound surface soil, and vegetation were collected at Area G and at off-site background locations. The samples were analyzed for 241 Am, 238 Pu, 239 Pu, 3 H, and total U. A comparison of radionuclide concentrations in mound soil to surface soil and in gophers to soil and vegetation implied that gopher activity is generally not resulting in the upward transport of radionuclides. Concentrations of 241 Am, 238 Pu, 239 Pu, and 3 H in some of the gopher, soil, and vegetation samples were higher than background at some of the sites, however, gophers at only one site within Area G had 3 H concentrations that resulted in an estimated dose to gophers that could impact their health. Relationships in radionuclide concentrations between the four media (pocket gophers, mound soil, off-mound surface soil, and vegetation) were examined by conducting correlation tests. Correlations were highest for Am 241 and 238 Pu, however, only the 238 Pu relationship may be accurate enough to be used in predicting concentrations. The relationship in radionuclide concentration between pelts and carcasses was highly variable carcasses, including the gastrointestinal tract, contained between 51% and 575% of the radionuclide concentration on pelts. Data generated by this study are valuable for ecological risk assessments. Further investigation through modeling and monitoring may be necessary to determine if the 3 H shafts are a source of environmental 3 H levels that are of ecological concern. Future research should include modeling the transport of radionuclides through ecological receptors within and around Area G. This should include investigations of transfer to high-level carnivores, especially raptors.

Proterozoic anorthosite plutonic suites consist of vast quantities (as much as 20,000 km (super 2) ) of cumulate anorthosite-leucotroctolite-leuconorite, intrusions of troctolite and Fe-enriched dioritic rocks, and large granitic batholiths. Crystallization ages span nearly 1,200 m.y. within the Middle Proterozoic (2.12-0.92 Ga). Many Proterozoic anorthosite plutonic suites were emplaced into relatively young Proterozoic crust and some were intruded along Archean-Proterozoic boundaries (e.g., Nain, Labrador; Laramie, Wyoming; Korosten, Ukraine). Nearly all of the largest plutonic suites contain significant areas (thousands of km (super 2) ) of plagioclase-rich cumulate rocks that are olivine bearing (olivine anorthosite-leucotroctolite). Troctolitic rocks (20-30% modal olivine) occur in Proterozoic anorthosite plutonic suites, principally as cumulates in layered or massive intrusions (e.g., Kiglapait, Hettasch, Jonathon-Nain) intruded into anorthositic rocks. With the notable exception of the Voisey's Bay deposit, nearly all troctolitic rocks crystallized late in the evolution of individual plutonic suites. Many of the troctolitic intrusions have fine-grained olivine-rich marginal rocks that closely represent parental magma compositions. Numerous fine-grained olivine-normative dikes with high Al basaltic compositions also occur within many plutonic suites (Nain, Harp Lake, Laramie, Adirondack) and share compositional characteristics with the troctolitic magmas. These olivine-normative high Al basaltic magmas record the least evolved compositions in Proterozoic anorthosite plutonic suites (Mg# = 0.43-0.64; An = 45-60), have high Al (sub 2) O (sub 3) (15-19 wt %) and FeO (sub total) (9-15 wt %) contents, and typically show the least contaminated Sr and Nd isotope compositions in a given plutonic suite. Many dikes and marginal rocks have strong positive Eu anomalies, a feature of the melt composition that is not related to plagioclase accumulation. Except at Laramie, the least evolved troctolitic magmas appear to have about 8 wt percent MgO and corresponding Ni and S concentrations between 100 to 150 ppm and 0.02 to 0.05 wt percent, respectively. Based on closed-system fractionation in the Kiglapait intrusion, sulfide saturation occurs late in the crystallization history of troctolitic magmas, after Ni concentrations have been severely depleted by protracted olivine fractionation. The optimal conditions for formation of a Ni-Cu sulfide deposit associated with a Proterozoic anorthosite plutonic suite require a relatively high MgO parental magma that has not crystallized much prior olivine and an external source of S to promote early sulfide saturation, probably through desulfurization reactions as hot troctolitic magmas ascend through the crust. An economically important massive Ni-Cu sulfide deposit on the scale of Voisey's Bay clearly requires large volumes of magma, probably involving continuous replenishment of relatively Ni rich, unfractionated parental magma in staging chambers or mixing between magmas in conduits during ascent. A model for the formation of troctolite-associated massive Ni-Cu sulfide deposits is proposed. Depending on the relative degrees of sulfide saturation and fractionation of the mixed magmas, mixing between troctolitic magmas in a conduit or magma chamber may either poison the system, stopping sulfide segregation, or enhance sulfide segregation.

Expressing the distorted shape of nonlinear resonances in terms of shifts in the resonant frequency and Q enables correlation analysis of these functions against components of the strain response function. Resonance shifts are found to be strongly correlated with somewhat complicated functions of strain, but only weakly with frequency or phase of the response. Decomposing the data along contours of constant strain magnitude yields the quantitative scaling of resonance shifts with strain, which shows a superposition of both conventional and necessarily hysteretic nonlinear sources. No statistically significant temperature dependence is found in the coefficients of the fits. Copyright 2000 by the American Geophysical Union.

Enrichment was as high as 3.7. The delta super(13)C of sewage-affected corals suggests they maintained a high degree of autotrophic nutrition. super(15)N-enriched wastewater dissolved inorganic nitrogen (DIN), derived from untreated sewage, is the most likely cause for enrichment in coral tissue super(15)N, though changes in coral nutrition, metabolism and zooxanthellae population dynamics are possible additional factors. Isotopic measurements of coral tissue can provide a simple means of detecting wastewater uptake by corals.

In contrast, the lower portions of the river accumulate runoff from thunderstorms of the summer monsoon season. Thus, the waters of the Rio Grande are strongly influenced by regional climate and could be vulnerable to climate change. In order to study water resources in the Rio Grande Basin and how they may be affected by changes in regional climate, a modeling system, which relies on the use of coupled atmospheric, runoff, and ground water models, is being developed. Preliminary work on the project has focused on winter precipitation simulations of the upper Rio Grande Basin and evaluation of the suitability of the atmospheric model for simulating regional climate. This paper describes the spatial and temporal precipitation variability predicted by this model. To examine the temporal variability, results of simulations carried out with the Regional Atmospheric Modeling System (RAMS), at 20 km resolution, are presented for the month of January 1996, representing a dry extreme for the region, and January 1993, representing a recent wet extreme. Results are also presented of a case study with higher resolution (5 km) over the upper Rio Grande Basin to examine spatial variability of the snowpack within complex terrain. The simulation results are compared to observations of daily-accumulated precipitation in the region. The comparisons of model predicted precipitation indicate that the RAMS model can reproduce the interannual changes in precipitation patterns found in the western US. In the month of January 1996, both RAMS and observed precipitation are highest in the northern mountain ranges of the domain. Likewise, in the month of January 1993, both predicted and observed precipitation in the southern tier of states are dramatically higher. Results of the simulations with increased model grid resolution indicate a modest improvement of precipitation estimates with the finer grid resolution over the Rio Grande Basin.

Four soil communities representing two pinyon rhizosphere and two between-tree (interspace) soil environments were compared by analysis of 16S rRNA gene clone libraries and culture collections (Dunbar et al., Appl. Environ. Microbiol. 65:1662-1669, 1998) and by analysis of 16S rDNA TRF profiles of community DNA. The TRF method was able to differentiate the four communities in a manner consistent with previous comparisons of the communities by analysis of 16S rDNA clone libraries. TRF profiles were not useful for calculating and comparing traditional community richness or evenness values among the four soil environments. Statistics calculated from RsaI, HhaI, HaeIII, and MspI profiles of each community were inconsistent, and the combined data were not significantly different between samples. The detection sensitivity of the method was tested. In standard PCRs, a seeded population comprising 0.1 to 1% of the total community could be detected. The combined results demonstrate that TRF analysis is an excellent method for rapidly comparing the relationships between bacterial communities in environmental samples. However, for highly complex communities, the method appears unable to provide classical measures of relative community diversity.

A delta D vs. delta (super 18) O plot shows that condensed waters from the gases are mixtures of meteoric and magmatic components, but that the apparent magmatic end-member in 1994 was depleted by about 7 per mil in delta D relative to the apparent end-member in 1980. Based on delta D modeling, approximately 63% of shallow, post-1980 magma has yet to degas. Surprisingly, Cl and F contents in the 1994 samples were only 0.47 and 3.8%, respectively, of the concentrations determined for end-member magmatic fluid in 1980. The data indicate that Cl (and F and B) is degassed from magma relatively quickly compared to water and/or that most of the Cl degassed in later years is dissolved into the shallow Mount St. Helens hydrothermal system. Because metals are often transported in magmatic and hydrothermal fluids as Cl complexes, rapid changes in surface volatile compositions may have implications for the timing and location of metals transport and deposition in some volcanoes.

The Carpinteria Field in the Santa Barbara channel is part of a turbidite reservoir. This mature field has produced over 100 million barrels of oil todate, with over 200 wells. Even with this production history and extensively available data, a comprehensive geological model was not available when the current operator purchased the field. The operator recognized in order to further develop the field it was necessary to integrate the extensive geologic data and develop a comprehensive model of the field. The company joined a cooperative research and development agreement with the Los Alamos National Laboratory. The aim of the project was to use advanced computational and visualization tools in developing the geologic model. The royalty owners of the field, both the federal and state governments also joined the project in a unique partnership. The project has resulted in a geologic model for the structure of the field. The model was used extensively during the planning stages of a recent, widely successful redevelopment plan for the field. The model was also used to perform a history match on a part of the field. These attempts were unsuccessful because of the commingled production and limited production allocation data. Currently, advanced geostatistical techniques are used to generate detailed distribution of reservoir heterogeneities. The goal is to develop a detailed rock properties distribution and associated measures of uncertainty, which can be helpful to the operator in further development of the field. The paper will discuss the application of various modeling techniques and the results.

Colloidal particle size distributions and total particle concentration in groundwater samples are quantified and characterized. Colloid materials from cavity waters collected near underground nuclear explosion sites by HRMP field sampling personnel at the Nevada Test Site (NTS) were quantified. Selected colloid samples were further characterized by electron microscope to evaluate the colloid shapes, elemental compositions, and mineral phases. The authors have evaluated the colloid size and concentration in the natural groundwater sample that was collected from the ER-20-5 well and stored in a 50-gallon (about 200-liter) barrel for several months. This groundwater sample was studied because HRMP personnel have identified trace levels of radionuclides in the water sample. Colloid results show that even though the water sample had filtered through a series of Millipore filters, high-colloid concentrations were identified in all unfiltered and filtered samples. They had studied the samples that were diluted with distilled water and found that diluted samples contained more colloids than the undiluted ones. These results imply that colloids are probably not stable during the storage, filtration, and dilution processes. They have evaluated possible sources of colloid contamination associated with sample collection, filtrating, storage, and analyses of natural groundwaters.

At high temperatures, they behave like metals. But as temperature is reduced, an energy gap opens in the conduction band at the Fermi energy and the materials become insulating. This contrasts with other f-electron compounds, which are metallic at all temperatures. The formation of the gap in Kondo insulators has been proposed to be a consequence of hybridization between the conduction band and the f-electron levels, giving a 'spin' gap. If this is indeed the case, metallic behaviour should be recovered when the gap is closed by changing external parameters, such as magnetic field or pressure. Some experimental evidence suggests that the gap can be closed in SmB sub(6) (refs 5, 8) and YbB sub(12) (ref. 9). Here we present specific-heat measurements of Ce sub(3)Bi sub(4)Pt sub(3) in d.c. and pulsed magnetic fields up to 60 tesla. Numerical results and theanalysis of our data using the Coqblin-Schrieffer model demonstrate unambiguously a field-induced insulator-to-metal transition.

Here, elevated levels of U occur in soils and the pond sediments associated with irrigated agricultural activities and associated naturally occurring U. Uranium is homogeneously distributed at a scale > 10 mu m; the ratio of U(VI) to U(IV) decreases with depth in the soil profile. Two luminescent U(VI) species in the surface sediments are a U(VI)-tricarbonate phase and a U(VI)-hydroxide or hydroxycarbonate phase. The distribution of the luminescent U(VI) species is unaffected by strongly acidic, basic and oxidizing solutions.

This study focused on the conformational structure of the bacterial exopolymer, gamma -D-poly(glutamic acid) and its interactions with U(VI) examined using ATR-FTIR spectroscopy. Solution pH, polymer concentration, and ionic strength affected the conformation of the exopolymer, and U(VI) binding was monitored. At low pH, low concentration, or low ionic strength, this exopolymer exists in an alpha -helical conformation, while at high pH, concentration, or ionic strength the exopolymer exhibits a beta -sheet structure. The change in exopolymer conformation is likely to influence the number and nature of exposed surface functional groups, sites most responsible for metal complexation. We found the polyglutamate capsule binds U(VI) in a binuclear, bidentate fashion; in contrast the glutamate monomer forms a mononuclear, bidentate complex with U(VI). The apparent polynuclear binding of U(VI) may induce beta -sheet structure formation provided the U(VI) concentration is sufficiently high.

Water analyses and thin section (glass slide) precipitation experiments were conducted to determine the aqueous processes controlling CaCO sub(3) precipitation and travertine landform formation. Results from the travertine flow indicate that the concentrations of HCO super(-) sub(3), Ca super(+2), and H super(+) decrease regularly along the flow paths. Chemical equilibrium modeling results demonstrate the importance of CO sub(2) out-gassing and CaCO sub(3) precipitation processes. CO sub(2) out-gassing and CaCO sub(3) precipitation increase with increasing flow velocities. In the pool area, varying hydrodynamics are the primary factors which determine the extent of processes such as advection and diffusion, and hence also control CaCO sub(3) precipitation and CO sub(2) out-gassing. When the pool water circulation is very slow, the pH of water flowing over the travertine dams increases significantly (approximately 0.15 pH units) downstream. When the circulation is relatively fast, the pH of stream water initially decreases followed by an increase of approximately 0.21 pH units as it flows past the travertine pool dams. In both cases, the pH rise is caused by sudden changes in the hydrodynamics of the pools, despite the different initial flow conditions. Pool development is a consequence of spatial variations in pH which provide different conditions for CaCO sub(3) precipitation inside the travertine dam, where less precipitation or even dissolution occurs, compared to conditions at the top and downstream side of the dams. Precipitation experiments demonstrate that the top and downstream side of travertine dams are the locations of the most active precipitation, particularly for pools having faster circulation. Precipitation experiments also reveal that vaterite, a rare polymorph of CaCO sub(3), co-precipitates with calcite in milky opalescent water near the upstream input portion of the pool groups. Thin sections covered by algae at the bottom of pools have 40% less CaCO sub(3) precipitation than those not covered by algae. SEM photographs of the surface of natural travertine deposits show that biofilms with diatom minimize CaCO sub(3) precipitation and that diatom-adhered calcite surfaces show signs of etching, suggesting that calcite dissolution may be aided by diatoms.

Analysis of dynamical quantities (such as fractal dimensions and Lyapunov exponents) has provided insights into low-dimensional systems; but it has proven more difficult to understand spatiotemporal chaos in high-dimensional systems, despite abundant data describing its statistical properties. Initial attempts have been made to extend the dynamical approach to higher-dimensional systems, demonstrating numerically that the spatiotemporal chaos in several simple models is extensive (the number of dynamical degrees of freedom scales with the system volume). Here we report a computational investigation of a phenomenon found in nature, 'spiral defect' chaos in Rayleigh-Benard convection, in which we find that the spatiotemporal chaos in this state is extensive and characterized by about a hundred dynamical degrees of freedom. By studying the detailed space-time evolution of the dynamical degrees of freedom, we find that the mechanism for the generation of chaotic disorder is spatially and temporally localized to events associated with the creation and annihilation of defects.

AN - 71091297; 10803902 AB - Rhodococcus rhodochrous strain OFS grew on toluene as a sole source of carbon and energy with a maximum growth rate of 0.011 h(-1). Initial reaction products were extracted, derivatized and identified by GC-MS. Oxygen consumption studies indicated that OFS grown on an aliphatic substrate required an induction period before oxidizing toluene. OFS grown on toluene transformed an array of aromatic ground water pollutants including styrene, ethylbenzene and chlorobenzene. Products of these transformations were identified. The sole product of chlorobenzene biotransformation was 4-chlorophenol. Products from toluene oxidation included 3- and 4-methylcatechol as well as benzyl alcohol, p-cresol and cis-toluene dihydrodiol. The identification of these and the products of other aromatic substrate conversions affirm that oxidation occurred on the functional group as well as directly on the aromatic nucleus.

Compared to abyssal peridotites the Hellenic peridotites have a highly depleted mineralogy (<1% modal cpx) and the cpxs have extremely low concentrations in Ti (30-150 ppm) and heavy REE. The light and middle REE, Zr and Sr contents of the cpxs show enrichments compared to cpx from abyssal peridotites. Our cpx data falls in the field of previous studies on modern arc peridotites ([Parkinson, I. J., Pearce, J. A., Thirwall, M. F., Johnson, K. T. M., Ingram, G., 1992. Trace element geochemistry of peridotites from the Izu-Bonin-Mariana forearc, Leg 125. In: Fryer, P., Pearce, J. A., Stokking, L. B. (Eds.), Proc. Ocean Drilling Program. pp. 487-506; Bonatti, unpubl.]) suggesting that these complexes originated above a subduction zone. Dry melting of an upper mantle source similar to a mid-ocean ridge basalt (MORB) source (e.g., [Johnson, K. T. M., Dick, H. J. B., Shimizu, N., 1990. Melting in the oceanic upper mantle: an ion microprobe study of diopsides in abyssal peridotites. J. Geophys. Res. 95, 2661-2678.]) cannot generate the extreme depletions in Ti and heavy rare earth element (HREE) seen in the cpxs from these supra-subduction zone (SSZ) peridotites. We propose that these high degrees of depletion can be achieved during hydrous melting of a MORB-depleted peridotite above a subduction zone. The melting rate of cpx during hydrous melting is expected to be less than in dry melting, while the rate of orthopyroxene (opx) consumption increases. These changes in melting modes allow for larger degrees of total melting and larger depletions in Ti and HREE in the cpx before cpx is exhausted from the residual peridotite. The enrichments in light rare earth element (LREE), MREE, Zr and Sr are best modeled by a constant flux of a slab-derived fluid component to the mantle wedge during melting. Ti and the HREE are not mobile in this fluid and are not enriched in the mantle peridotite. The continuous flux is necessary to sustain hydrous melting in the sub-arc mantle during the complete melting range. The calculated fluid composition matches well previous estimates based on the arc basalt chemistry ([McCulloch, M. T., Gamble, J. A., 1991. Geochemical and geodynamical constraints on subduction zone magmatism. Earth Planet. Sci. Lett. 102, 358-374; Stolper, E., Newman, S., 1994. The role of water in the petrogenesis of Mariana trough magmas. Earth Planet. Sci. Lett. 121, 293-325.]) and experiments on fluids ([Ayers, J. C., Dittmer, S. K., Graham, D. L., 1997. Partitioning of elements between peridotite and H (sub 2) O at 2.0-3.0 GPa and 900-1100 degrees C, and application to models of subduction zone processes. Earth Planet. Sci. Lett. 150, 381-398; Ayers, J. C., 1998. Trace element modeling of aqueous fluid-peridotite interaction in the mantle wedge of subduction zones. Contrib. Mineral. Petrol. 132, 390-404.]). The resulting melts from our model closely resemble melts from an arc environment (boninites) further arguing for the plausibility of this model.

The field studied, the Carpinteria Field, is part of an offshore turbidite field. The study involves integrating information including, core, log and pressure test data from over 200 wells. The Carpinteria Field is contained within a geologically young, faulted anticlinal fold. Careful log analyses have resulted in identification of 29 Repettian productive sands in the field. Several companies have operated various parts of the field since its discovery leading to the lack of a single field-wide interpretation that integrates the extensive geologic and engineering data. Careful reconciliation of existing interpretations and reinterpretation of the legacy data have led to an integrated, consistent geologic structural model of the reservoir. Initially, the model was populated with rock properties using deterministic interpolation techniques. Validation of the geologic model with a history match exercise has not been feasible. It was thought that in the absence of a history match exercise, confidence in the geologic model could be increased through further, detailed characterization of the reservoir. The geologic and engineering data from multiple sources have been carefully integrated using advanced geostatistical techniques. Multiple realizations of rock properties' distributions are being generated using geostatistical simulation techniques. These realizations will be used to quantify the uncertainty associated with the distributions. The comprehensive geologic model and the associated uncertainty will be useful to the field operator in designing and evaluating alternate field development scenarios.

Pore scale results are analyzed to give quantities such as permeability, porosity and specific surface area at various scales and at various locations. With this, some fundamental issues such as scale dependency and medium variability can be assessed quantitatively. More specifically, the existence and size of the well known concept, representative elementary volume (REV), can be quantified. It is found that the size of an REV varies spatially and depends on the quantity being represented. For heterogeneous media, a better measure may be the so called "statistical REV", which has weaker requirements than does the deterministic REV. Copyright 2000 by the American Geophysical Union.

The spatial variabilities in both the fracture and matrix continua motivate us to treat some of the fracture and matrix medium properties as stochastic processes. Hence flow through heterogeneous, fractured porous media is also amenable to stochastic analysis. In particular, we develop a moment equation-based stochastic theory for flow in fractured porous media. We derive general equations governing the statistical moments of the pressure heads in such media by perturbation expansions. The solutions of these moment equations are the first two moments of the pressure heads. These may be used to construct the confidence intervals of the fracture and matrix pressure heads, which are measures of uncertainties caused by incomplete knowledge of the fracture and matrix medium heterogeneities. The resulting moment equations of pressure heads are coupled and need to be solved sequentially in an iterative manner. The two-dimensional version of the equations is implemented numerically and illustrated with some examples.

Tritium at relatively low levels (0.1-5 T.U.) is found in most emissions from high-temperature volcanic fumaroles sampled, even at discharge temperatures >700 degree C. Although magmatic fluids sampled from these emissions usually contain high CO sub(2), S sub(total), HCl, HF, B, Br, super(3)He R/R sub(A), and low contents of air components, stable isotope and tritium relations of nearly all such fluids show mixing of magmatic volatiles with relatively young meteoric water (model ages 75 y). Linear delta D/ delta super(18)O and super(3)H/ delta super(18)O mixing trends of these two end-members are invariably detected at arc volcanoes. Tritium is also detected in fumarole condensates at hot spot basalt volcanoes, but collecting samples approaching the composition of end-member magmatic fluid is exceedingly difficult. In situ production of super(3)H, mostly from spontaneous fission of super(238)U in magmas is calculated to be 0.05 T.U.).

In marked contrast to these slow global dynamics, hydrogen exchange experiments here demonstrate that conformational opening for solvent access occurs in the approximately millisecond time frame or faster at 28 degree C for all amide positions. Under these conditions all backbone amides with exchange protection factors between 10 super(4) and 10 super(6), for which EX sub(2) exchange kinetics were directly verified, have exchange activation energy values within 2-3 kcal/mol of that observed for unstructured peptides. The conformational flexibility of this protein is thus sufficient for water and base catalyst access to the exchanging amide with quite limited structural disruption. The common hypothesis that enhanced conformational rigidity in the folded native state underlies the increased thermal stability of hyperthermophile proteins is not supported by these data.

Herein, we introduce a new type of kinetics experiment that shows how different unfolding pathways can be selected by varying the initial reaction conditions. The relaxation kinetics of the major cold shock protein of Escherichia coli (CspA) in response to a laser-induced temperature jump are exponential for small temperature jumps, indicative of folding through a two-state mechanism. However, for larger jumps, the kinetics become strongly nonexponential, implying the existence of multiple unfolding pathways. We provide evidence that both unfolding across an energy barrier and diffusive downhill unfolding can occur simultaneously in the same ensemble and provide the experimental requirements for these to be observed.

AN - 71069915; 10782199 AB - To evaluate a portable photoionization detector for assessing personal exposure to solvent mixtures, a set of 26 side-by-side, time-weighted average (TWA) personal breathing zone samples were collected during various construction painting tasks by two different sampling methods: (1) standard charcoal sorbent tubes analyzed by gas chromatography (CST/GC), and (2) a direct-reading photoionization detector coupled with an extended data-logger (PID). The TWA concentrations of the hydrocarbons detected by CST/GC analysis were summed for comparison with the TWA concentration obtained from the direct-reading PID. Based on linear regression between the log TWA concentrations of the two sampling methods, the data were highly correlated (r2 = 0.95). Since the solvents had effects that may be considered additive, threshold limit values (TLVs) for mixtures were developed using American Conference of Governmental Industrial Hygienists formulas to evaluate solvent exposure. The logs of the TLV mixture data from the sampling methods were highly correlated (r2 = 0.94). Based on the linear regression analyses, the response of the portable PID was highly correlated to the CST/GC results for hydrocarbon mixtures encountered during various painting tasks. Due to the short duration of tasks, highly fluctuating exposures, and complexity of the mixtures, the PID may provide the most cost-effective, detailed exposure assessment for solvent mixtures.

AN - 70982781; 10728689 AB - Increases in cell proliferation are widely viewed as being of importance in carcinogenesis. We report that exposure of normal human lung fibroblasts to a low dose of alpha particles like those emitted by radon/radon progeny stimulates their proliferation in vitro, and this response also occurs when unirradiated cells are treated with supernatants from alpha-irradiated cells. We attribute the promitogenic response to superoxide dismutase- and catalase-inhibitable a particle-induced increases in the concentrations of transforming growth factor beta1 (TGF-beta1) in cell supernatants. TGF-beta1 at concentrations commensurate with those in the supernatants capably induces increases in intracellular reactive oxygen species (ROS) in unirradiated cells. Furthermore, the addition of supernatants from alpha-irradiated cells to unirradiated cells decreases cellular levels of TP53 and CDKN1A and increases CDC2 and proliferating cell nuclear antigen in the latter. Like the increased intracellular ROS bystander effect, this "decreased TP53/CDKN1A response" can be mimicked in otherwise untreated cells by the addition of low concentrations of TGF-beta1. Our results indicate that alpha particle-associated increases in cell growth correlate with intracellular increases in ROS along with decreases in TP53 and CDKN1A, and that these cellular responses are mechanistically coupled. As well, the proliferating cell nuclear antigen and CDC2 increases that occur along with the decreased TP53/CDKN1A bystander effect also would expectedly favor enhanced cell growth. Such processes may account for cell hyperplastic responses in the conducting airways of the lower respiratory track that occur after inhalation exposure to radon/ radon progeny, as well as, perhaps, other ROS-associated environmental stresses.

Large irregular fractures, fissures and other voids occur along the upper and lower contacts of successive basalt flows in this broad, NE-trending structural depression, forming major conduits of water transport in the aquifer. The results show a wide range of radioactivities, and the resulting radioactive disequilibria combined with the range of decay lives involved, enable estimates to be made of the rates of water transport and rock-water interaction spanning various time scales. Estimates of the in situ retardation factors (the ratio of flow rates of fluid to those of dissolved radionuclides) are of the order of 10 (super 6) for Th, 10 (super 4) for (super 226) Ra and 10 (super 3) for (super 238) U. Subsurface water transit times range from approximately 1 yr in the N, to approximately 100 yr in the central and SW parts of the INEEL area. The decay-series disequilibria in groundwater are explained by a sorbed pool of radionuclides which are exchangeable with their dissolved counterparts through sorption/desorption.

We solve moment equations derived from a stochastic mathematical statement of immiscible nonlinear two-phase flow in heterogeneous reservoirs. Our stochastic approach is different from the Monte Carlo approach. In the Monte Carlo approach, the prediction uncertainty is obtained through a statistical post-processing of flow simulations, one for each of a large number of equiprobable realizations of the reservoir description. We treat permeability as a random space function. In turn, saturation and flow velocity are random fields. We operate in a Lagrangian framework to deal with the transport problem. That is, we transform to a coordinate system attached to streamlines (time, travel time, and transverse displacements). We retain the normal Eulerian (space and time) framework for the total velocity, which we take to be dominated by the heterogeneity of the reservoir. We derive and solve expressions for the first (mean) and second (variance) moments of the quantities of interest. We demonstrate the applicability of our approach to complex flow geometry. Closed outer boundaries and converging/diverging flows due to the presence of sources/sinks require special mathematical and numerical treatments. General expressions for the moments of total velocity, travel time, transverse displacement, water saturation, production rate, and cumulative recovery are presented and analyzed. A detailed comparison of the moment solution approach with high-resolution Monte Carlo simulations for a variety of two-dimensional problems is presented. We also discuss the advantages and limits of the applicability of the moment equation approach relative to the Monte Carlo approach.

LANL developed this screening approach in partnership with personnel from the State of New Mexico regulatory authority (the New Mexico Environment Department or NMED). A key part of the screening evaluation process is the completion of an innovative ecological scoping checklist. This checklist helps to (1) determine if complete pathways to ecological receptors exist; (2) determine how the impacted media should be aggregated spatially for screening, establishing the functional/operational boundaries of the assessment; and (3) gather information to develop the site conceptual model (SCM). The SCM includes contaminant sources, dominant transport pathways and exposure routes, and potential receptors. The scoping checklist consists of a series of questions and placeholders for field notes, which are intended to guide the risk assessor in developing the SCM, and provide the decision-makers with consistent information on receptors, potential transport pathways and potential exposure pathways. This paper summarizes the LANL/NMED scoping checklist and gives examples of its application at the LANL Environmental Restoration (ER) sites.

Flow and transport are considered in the vertical cross-section. The Dupuit approximation and conformal mapping onto the complex potential domain are employed to determine the velocity and concentration distributions, respectively. We use this solution to derive a priori conditions under which widely used 1-D analytical solutions with constant velocity and dispersion coefficients provide accurate approximations. These conditions are formulated in terms of aquifer parameters, such as hydraulic conductivity, porosity and dispersivities, and remediation strategy, e.g., well spacing and pumping regimes.

Several models have been proposed to explain this anisotropy as the result of preferred orientation of crystals. They range from a large annealed single crystal, growth at the melt interface, to deformation-induced texture. In this study texture development by deformation during inner core convection is explored for epsilon -iron (hep) and gamma -iron (fcc). Convection patterns for harmonic degree two were investigated in detail. In the model it is assumed that traces of potassium are uniformly dispersed in the inner core and act as a heat source. Both for fee and hep iron, crystal rotations associated with intracrystalline slip during deformation can plausibly explain a 1-3% anisotropy in P waves with faster velocities along the N-S axis and slower ones in the equatorial plane. The effect of single crystal elastic constants is explored. Copyright 2000 by the American Geophysical Union.

It has been found recently that the presence of the water table significantly affects unsaturated flow in a heterogeneous vadose zone and causes the flow to be spatially nonstationary. Because a vadose zone is by definition bounded by the water table at the bottom and the contaminants present in the vadose zone migrate into the groundwater through the water table, it is of great interest to study the behaviors of a solute plume near the water table and the effects of flow nonstationarity caused by the water table on solute spreading. To do so, we develop a Lagrangian stochastic approach for predicting field-scale solute spreading in a spatially nonstationary velocity field. Through first-order approximations the statistical moments of particle displacement are related to the moments of the Eulerian velocity field. Closed form expressions are obtained for the special case of unidirectional but nonuniform mean flow such as vertical infiltration. We illustrate our theoretical developments with some one-dimensional examples of solute transport during steady state infiltration in bounded vadose zones. It is found that the inclusion of the water table significantly impacts the behaviors of the mean particle displacement and the displacement covariance, which quantify expected solute displacement and spreading about the expected value, respectively. At late times the particle displacement covariance is generally much smaller when the effect of the water table is included than when it is neglected. In particular, for the case of one-dimensional infiltration in a bounded vadose zone the particle displacement covariance decreases with time at late times. This finding is in contrast to the result that the particle displacement covariance increases linearly at late times as found by previous stochastic studies of solute transport in unbounded vadose zones. Hence macrodispersion may be greatly overestimated in previous stochastic studies that disregarded the presence of the water table. The validity of the theoretical approach developed in this paper is investigated and confirmed by Monte Carlo simulations. Copyright 2000 by the American Geophysical Union.

AN - 70933375; 10706294 AB - Small molecules such as NO, O2, CO or H2 are important biological ligands that bind to metalloproteins to function crucially in processes such as signal transduction, respiration and catalysis. A key issue for understanding the regulation of reaction mechanisms in these systems is whether ligands gain access to the binding sites through specific channels and docking sites, or by random diffusion through the protein matrix. A model system for studying this issue is myoglobin, a simple haem protein. Myoglobin has been studied extensively by spectroscopy, crystallography, computation and theory. It serves as an aid to oxygen diffusion but also binds carbon monoxide, a byproduct of endogenous haem catabolism. Molecular dynamics simulations, random mutagenesis and flash photolysis studies indicate that ligand migration occurs through a limited number of pathways involving docking sites. Here we report the 1.4 A resolution crystal structure of a ligand-binding intermediate in carbonmonoxy myoglobin that may have far-reaching implications for understanding the dynamics of ligand binding and catalysis.

Although this method is sensitive it gives no information on cell viability or responding lymphocyte subsets. We have developed reliable and simple flow cytometric assays for lymphocyte proliferation testing (Immuno-Be-LPT) by combining immunophenotyping with bromodeoxyuridine (BrdU) incorporation or DNA content using propidium iodide (PI) or 4'6'-diimidazolin-2-phenylindole (DAPI). Evaluation of beryllium-induced lymphocyte proliferation in blood cells from seven patients with chronic beryllium disease (CBD) and 120 beryllium workers by both the Be-LPT and the Immuno-Be-LPT showed agreement between the tests. The Immuno-Be-LPT provided additional information about the specific type of lymphocytes responding. CD4 + lymphocytes proliferated in response to beryllium in blood samples from all seven CBD individuals and CD8 + lymphocytes proliferated in six of the seven. Four beryllium workers without CBD had positive responses to beryllium primarily in the CD8 + cells. The use of the individual's own plasma supported a greater beryllium or tetanus-induced proliferation of CD4 + lymphocytes when compared to commercial human serum. The response of CD4 + lymphocytes measured in the Immuno-Be-LPT may provide a new marker for the diagnosis of CBD.

The two clusters were chosen from a collection of clusters identified within a 16,000-event data set obtained in 1993. I determined P- and S- wave arrival times, manually, choosing distinctive peaks if waveforms were similar at a given station, or first breaks if waveforms were emergent or nodal, judging weights accordingly. Requiring a minimum of five arrival times yielded populous clusters of 226 and 355 events. In both cases, relocation revealed two distinct planar patches of activity, 100 to 200 m across, intersecting and truncating one another along a common edge. Linear segments traverse the planar patches and may mark intersections with seismically inactive fractures. The earliest activity occurred along these segments. These segments may therefore mark permeable zones that could be important components of the fluid-flow network. The interpretation of linear segments as flow paths is supported by path dimension constraints derived from fluid-flow modeling studies and by the expected confining effects of hydrothermal sealing found in cored fractures. Orientations of the planar features are verified through consistency with orientations found in core and logging studies. In addition, focal mechanisms obtained by constraining slip planes parallel to active planes indicate normal to right-lateral strike slip, consistent with the measured stress field. Focal mechanisms indicate mass deficits at inside corners, implying that the concentrations of activity at fracture intersections may result from slip on one fracture causing extension and a resulting permeability increase in the other. The improved location precision results from a ten-fold improvement in the precision of arrival-time estimation for phases that were similar, as estimated from the standard deviation of residuals, grouped by station and phase, before and after repicking. Only a two-fold improvement was noted for poorly correlated or nodal phases. For this data set, the manual phase picking yielded more interpretable detail in the location patterns, compared to results of an automatic, cross-correlation technique. The manual results could be used to guide improvements to automatic techniques to obtain precise locations of the entire data set.

The vibrational spectra showed that H (sub 2) O sorbed to the clay at low-water content was strongly influenced by the exchangeable cation and by the close proximity to the clay surface. At water contents <6 H (sub 2) O molecules per exchangeable cation, the H-O-H bending mode of H (sub 2) O (v (sub 2) mode) shifts to a lower frequency and is characterized by an increase in molar absorptivity. In contrast, the positions of the asymmetric and symmetric OH-stretching modes of sorbed water (v (sub 1) and v (sub 3) modes) shift to higher energies. These observations indicate that H (sub 2) O molecules sorbed to the clay surface at low-water content are less hydrogen bonded than in bulk H (sub 2) O. In addition, the vibrational-stretching and bending bands of the structural OH groups of the 2:1 layer are also strongly influenced by H (sub 2) O content and type of exchangeable cation. By using the EIRM cell, the molar absorptivities of the structural OH-bending vibrations were measured as a function of H (sub 2) O content. The position and molar absorptivity of the structural OH-bending bands at 920, 883, and 840 cm (super -1) are strongly influenced by H (sub 2) O content and type of exchangeable cation. The molar absorptivity of the 920-cm (super -1) band, which is assigned to the AlAlOH group, decreased strongly at low-H (sub 2) O content. This reduction in intensity is assigned to a dehydration-induced change in orientation of the structural OH groups resulting from the penetration of H (sub 2) O molecules into siloxane ditrigonal cavities that are not associated with a net negative charge from isomorphous substitutions.

Simulations use the finite element approach to solve the governing equations for a problem, wherein air mass, water mass, and energy are conserved. We use a computational grid that maintains complex topographic and stratigraphic boundaries. The 30 m of topographic relief at the site allows atmospheric communication with the subsurface air and water vapor within the mesa. Time-dependent heat and gas generated in the landfill through the decomposition of organic waste provide the main driving forces for vapor phase migration. We show that the magnitude of vapor phase migration is primarily controlled by gas generation source strength. Increased temperature has a secondary effect on vapor phase flux. Flow paths change considerably from pre-landfill to post-landfill conditions. Pre-landfill upflow of air through the mesa with maximum flux of 2 cm/yr is driven by ambient density gradients. Post-landfill gas input reverses the direction of flow beneath the landfill, forcing gas into dry, permeable pathways that lead into the mesa. Vapor advection along high permeability zones beneath the landfill may explain observations of landfill gas found at depth. Post-landfill vapor flux most likely peaked with a maximum flux on the order of 30 m/yr, within the first 20 years since closure. Advective transport of gas below the landfill is shown to dominate during the high productivity phase of gas generation. Transport of landfill gas is shown to be dominated by diffusion when the vapor phase flux falls below 1 to 3 m/yr.

Mountainous topography up to 2000 m lines the Mediterranean coastal margin of Cataluna (Spain) despite a crustal thickness of 22 km at the coast. Geometric analysis of topographic profiles indicates a strong link between topography and extensional tectonics. Trends in maximum, mean and minimum elevations show marked regional increases in a SW-NE direction along the axis of the Ebro basin towards the active Amer-Brugent normal fault. From patterns of local relief, characteristics of the fluvial drainage network, location of drainage divides, and degree of escarpment retreat, we distinguish two overlapping areas of mountainous topography, a southern area related to late Oligocene to middle Miocene rifting and a northern area related to late Miocene to Quaternary rifting. The youthful topography in the northern area likely results from mechanical unloading of the footwall of the Amer-Brugent normal fault. In the southern area (encompassing the Catalan Coastal Ranges), erosion continuously renews topography produced by rifting while causing headward erosion of coastal rivers into the Ebro basin. Elevated topography along the Catalan margin derives principally from flexural isostatic rebound due to tectonic and erosional denudation, causing exhumation of the rifted margin. Nonetheless, the height of the mountains and the thinness of the crust suggest an additional component of dynamic or thermal support of mountainous topography, likely buoyancy forces from density differences in the mantle.

Understory light varies along gradients of vegetation structure that range from grassland with no woody canopy cover to forest with nearly complete woody canopy cover. Spatial variability in understory light is largely determined by several characteristics of overstory plants -- spatial pattern, height, and cover -- which vary concurrently along the grassland/forest continuum. Using a spatially-explicit ray-tracing model, we quantified trends in mean and variance of understory light along the continuum. We modeled understory light over a growing season for two types of plots: (1) generated plots in which cover, spatial pattern, and height of trees were varied systematically, and (2) three actual plots using stand data from pinon-juniper woodland sites for which cover, spatial pattern and height varied concurrently. Mean understory light decreased with increasing canopy cover and was sensitive to changes in height, as expected, but was not sensitive to spatial pattern. Variance in understory light was maximum at an intermediate value of cover that was dependent on both spatial pattern and cover -- maximum variance occurred at lower values of cover as height increased and as spatial pattern progressed from regular to random to aggregated. These trends in the overall patterns of understory light were also examined with respect to changes in understory light in canopy and intercanopy locations. Variance in understory light for intercanopy locations was less than that for canopy locations at low canopy cover, but exceeded that for canopy locations as canopy cover increased. The value of canopy cover at which variance in intercanopy locations exceeded that in canopy locations was sensitive to variation in height but not in spatial pattern. The distributions of understory light for the actual plots were generally similar to those for corresponding generated plots, with dissimilarities attributable to differences in cover and height. The general trends highlighted by our simulations are broadly applicable to sites along the grassland/forest continuum.

Frijoles Canyon developed after deposition of the voluminous ignimbrites of the Tshirege Member of the Bandelier Tuff at ca. 1.22 Ma, which provides excellent temporal constraints on canyon evolution. Base level fall along the Rio Grande, the master drainage in the region, contributed to initial incision of the stream. Development of a major knickpoint in basalt near the Rio Grande, however, has effectively isolated most of the stream channel from direct effects of this base level change since the Early or Middle Pleistocene. Late Quaternary evolution of the channel has included development of strath and fill terraces that record the effects of climatic variations and local lithologic variations within the tuff on channel processes. A fill terrace, underlain by up to 13 m of coarse gravelly alluvium, records significant aggradation in the Early to Middle Holocene following a major regional climate change. Aggradation probably resulted from large increases in sediment supply in the Holocene relative to the Late Pleistocene, which was perhaps related to variations in intense summer rains. Rapid incision in the Middle to Late Holocene has stranded the underlying strath up to 21 m above the modern channel, and local rates of incision of up to 4 m/ka are more than 10 times the average rates since 1.22 Ma. Holocene incision displays great spatial variability associated with local lithologic variations, and results in a stream profile that has evolved rapidly in the last 10,000 years. The high rates of incision occur where easily eroded nonwelded tuff is exposed in the canyon bottom, whereas a more resistant vapor-phase altered tuff unit upstream has impeded incision. Incision may also have been affected by migration of knickpoints within the tuff. Paired strath terraces record periods of local base level stability and lateral erosion that were terminated by episodes of downcutting. The downcutting was probably controlled by rare high magnitude floods capable of stripping the pervasive gravel armor and exposing nonwelded tuff beneath the stream-bed. No tectonic influence on Late Quaternary terrace development or stream incision has been recognized despite Frijoles Canyon being crossed by the Pajarito fault zone, a major bounding structure of the Rio Grande Rift. Instead, climatic influences on sediment supply and flood characteristics, mediated by lithologic variations in the canyon bottom, have controlled Late Quaternary stream profile evolution.

However, there have been recent attempts to bridge the gap between speech production & speech recognition using models that are stochastic & yet make more reasonable assumptions about the mechanisms underlying speech production (Bakis, 1991; Deng, 1998; Hogden, 1998; Picone et al, 1999). One of these models, Multiple Observable Maximum Likelihood Continuity Mapping (MO-MALCOM) is described in this paper. There are theoretical & experimental reasons to believe that MO-MALCOM learns a stochastic mapping between articulator positions & speech acoustics. Furthermore, MO-MALCOM can be combined with standard speech recognition algorithms to form a speech recognition approach based on a production model. Results of experiments related to MO-MALCOM are summarized, & some implications for theories of speech production & speech perception are discussed. 18 References.

Here we describe techniques for remotely measuring volcanic gas composition, at ranges up to tens of kilometers, using ground-based passive infrared spectroscopy. The principles of passive infrared spectroscopic remote sensing are discussed, and the effects of thermal contrast on the detectability of gases in various viewing geometries are quantitatively examined. This examination reveals that, for ground-based measurements, a sky background usually provides the best results. Our initial remote sensing campaign (April-May, 1996) at the White Island and Ruapehu volcanoes in New Zealand, combining passive Fourier transform infrared (FTIR) spectroscopy with traditional COSPEC and direct sampling measurements, confirmed this and demonstrated spectroscopic detection of SO (sub 2) , H (sub 2) O and HCl at ranges of up to 6 km, with good agreement between FTIR-derived and direct sampling based gas ratios. In measurement campaigns at Mexico's Popocatepetl volcano (February 1997 and February 1998), we monitored variations of SO (sub 2) , SiF (sub 4) , HCl, and HF, and extended the range of sky-background passive infrared techniques to over 17 km. In the highest temporal resolution study to date of short-term compositional variations associated with an explosive eruption (25-26 February 1997), we observed a steady increase in SiF (sub 4) SO (sub 2) over several days preceding the eruption, followed by a tenfold decrease in this ratio over a few hours immediately afterwards, a signature suggesting an adiabatic expansion prior to and during a gas-driven explosion. We examine the ultimate range limits of ground-based passive FTIR spectroscopy and possible future extensions to imaging and airborne instruments.

The intra-caldera lacustrine sediments and interbedded ash deposits of the Creede Formation were sampled by research core holes Creede 1 and 2, drilled during the fall of 1991. An earlier study of the Creede Formation, based on surface outcrops and shallow mining company core holes, concluded that the process of caldera structural resurgence was rapid and that a caldera lake had developed in an annulus (moat) located between the resurgent dome and caldera wall. A picture has been developed of intracaldera activity consisting of intermittent hydrovolcanic eruptions within the caldera lake representing the lower third of the Creede Formation, and both magmatic and hydrovolcanic ash eruptions throughout the top two-thirds. Most of the ash deposits interbedded with the moat sedimentary rocks are extremely fine grained. Fallout into the moat lake and unconsolidated ash eroded from caldera walls and slopes of the resurgent dome were deposited by stream delta distributaries within relatively shallow water in the northwestern moat, and in deeper waters of the northern moat, where the caldera is intersected by a graben. Interbedded with ash beds and tuffaceous siltstones are coarse-grained turbidites from adjacent slopes and distal travertine beds from fissure ridges adjacent to the moat. Sedimentation rates and provenance for clastic sediments are linked to the frequent volcanic activity in and near the caldera; almost all of the Creede Formation sedimentary rocks are tuffaceous.

Guzman et al. applied a steady-state analysis to late-time data from each test. In this paper, type-curve analyses of transient data from those tests are described, which yielded information about air permeability, skin factor, dimensionless wellbore-storage coefficient, and dimensionality of the flow regime on a nominal scale of 1 m in the immediate vicinity of each test interval. Significant nonlinear effects such as inertia, turbulence, air compressibility, and two-phase flow were expected from air injection into unsaturated fractured tuffs. Type-curve interpretation revealed that the single-hole test data analyzed show little sensitivity to those nonlinearities and the method of linearization. Type-curve analysis was accomplished with the aid of various analytical continuum (radial, spherical) and fracture (horizontal, vertical) flow models as the initial qualitative assessment showed considerable variability of the transient behavior of data at different injection intervals. The fact that transient pressure behavior is not entirely consistent across the site, but varies from one test interval to another, provided a qualitative indication that the site is pneumatically nonuniform and the local rock is heterogeneous. Results show that most data fit the spherical flow type-curve model, implying that flow on the 1-m scale is three dimensional. Air permeabilities obtained from type-curve analyses agree well with values obtained through steady-state analyses. Overall, considerable insight was gained in terms of the local properties of unsaturated fractured rocks, the importance of non-linear effects, and the phenomenology of airflow through such rocks.

G. Guzman and coworkers in six shallow vertical and slanted bore-holes in unsaturated fractured tuffs at the Apache Leap Research Site near Superior, Arizona. Guzman and coworkers used steady-state formulae for single-phase air flow in a uniform, isotropic porous continuum to interpret late data from each step of an injection test. W. A. Illman and coworkers used transient type curves for single-phase air flow in a similar continuum to analyze all data from the first step of several injection tests; however, this analysis did not allow reliable identification of air-filled porosity and the dimensionless borehole storage coefficient. This chapter describes numerical inversion of multistep and recovery data from some of these same tests, based on similar assumptions, by means of a three-dimensional finite-volume code (FEHM) coupled with a parameter-estimation code (PEST). Our numerical inverse model accounts directly for the geometry, flow properties, and storage capabilities of open borehole intervals by treating them as high-permeability and high-porosity cylinders of finite length and radius. It also allows interpreting multiple injection-step and recovery data simultaneously, and yields information about air permeability, air-filled porosity, and the dimensionless borehole storage coefficient. Some of this is difficult to accomplish with the analytical type-curve method. Air permeability values obtained by our inverse method agree well with those obtained by steady-state and type-curve analyses.

Under the first-order approximation and uniform mean flow condition, the ensemble averages of the second spatial moments, Z (sub ii) , and associated effective dispersivities, gamma (sub ii) , were evaluated as functions of the dimensionless time for a line source of the dimensionless lengths, 1, 5, 10, and 20, either normal or parallel to the mean flow direction. The multiscale results are compared with those obtained previously for a single-scale medium. It is found that the multiscale results of Z (sub ii) and gamma (sub ii) follow a similar pattern of the single-scale results but they are strongly influenced by the value of the Hurst coefficient H (0 < H < 0.5): the larger the value of H, the smaller the difference between the results for the multiscale and those for the single-scale medium. The main differences between the results for the two media are: (1) the longitudinal spreading is weakened while the asymptotic transverse spreading is enhanced by the multiscale structure of log K field, (2) the ergodic limits are reached slower in the multiscale medium than in the single-scale medium as the dimensionless source length L (sub 2) increases, and (3) the preasymptotic period is longer in a multiscale medium than in a single-scale medium. These differences can be attributed to the longer time taken by solute particles of a finite plume to sample all the velocity variation in a multiscale medium than in a single-scale medium. In the multiscale medium the longitudinal moment approaches ergodic condition slower in three dimensions than in two dimensions as L (sub 2) increases. The negative effective transverse dispersivity, which was discovered for a single-scale medium, also exists for the case of a line source parallel to the mean flow in the multiscale medium, which calls for further study.

The vertical extend of the aquitards is finite, and constant-mean head boundaries apply in the planar direction. The log-hydraulic conductivity, Y(x), is considered to be Gaussian, statistically homogeneous, and described by an exponential auto-covariance function. We have performed numerical simulations to investigate the effect of (1) the dimensionless ratio L/lambda , L being the aquitards' vertical extend and lambda being the integral scale of Y(x); and (2) the variance of Y(x). The turning bands and sequential Gaussian simulation methods were used to generate the heterogeneous Y(x) fields, and a block-centered, seven-point finite difference scheme was utilized to solve the steady-state, three-dimensional, saturated flow equation. We have found that for small ratios of L/lambda , the arithmetic mean of hydraulic conductivities serves as a good approximation to equivalent homogeneous aquitards, whereas the behavior at large ratios (L/lambda >4) approaches that of equivalent infinite aquitards. Our results, for various finite ratios L/lambda and for variances of Y(x) to 7, support the analytical expressions developed in 1996 by Paleologos, Neuman, and Tartakovsky for bounded, strongly heterogeneous media. Our numerical results indicate that for statistically isotropic media and for infinite and/or finite flow domains, the exponential generalization of theoretical expressions developed through first-order analyses provides an accurate prediction of ensemble mean hydraulic behavior.

Closed-form analytical expressions for the particle displacement covariance and macrodispersion coefficient are only available for first-order analysis for a few correlation models of log-hydraulic conductivity. The methods used to obtain the analytical expressions usually require a specific correlation function of natural-log hydraulic conductivity. In this chapter we derive the general expressions for solute particle displacement covariance and macrodispersion coefficients. These expressions are simple and include only the correlation function of natural-log hydraulic conductivity. They are valid for any statistically isotropic log-hydraulic conductivity correlation function. Results are presented for several frequently used correlation functions of log-conductivity.

Yet, groundwater flow and transport dynamics are grossly oversimplified in most risk analyses. Existing geostatistical and stochastic methods for quantifying uncertainty (and hence, risk) in groundwater flow and transport predictions are widely ignored by the consulting industry as too complicated and expensive for hydrogeologic applications. To overcome this gap, an attempt is made in this paper to provide an intuitive rather than quantitative overview of these methods, which are considered to be the key for better groundwater risk analysis. The article explores the links between heterogeneous aquifer characteristization with limited data, geostatistical analysis, stochastic prediction, and quantification of contamination risk. Monte Carlo simulation is seen as the most likely tool for stochastic analysis in a consulting environment. A few key requirements for proper Monte Carlo simulation are summarized. Finally, a number of rules-of-thumb about aquifer heterogeneity and contaminant behavior in such heterogeneous environments are stated. These rules-of-thumb are derived from the large volume of stochastic theory literature.

The approach is based on the theory of small fluctuations of the logarithm of the permeability and models the response of the ensemble-average pressure, obtained by averaging the pressure response of multiple well tests. A nonlocal diffusivity equation for the ensemble-average pressure, which incorporates directly the permeability correlation function, is obtained, from the analysis of which the permeability semivariogram of the reservoir can, in principle, be constructed.

It is assumed that one can infer meaningful statistical information about hydraulic conductivity, such as its ensemble mean, variance, and covariance, from available data. Our numerical finite element analysis consists of directly evaluating the Green's function for the mean field and subsequently solving (conditional) nonlocal moments equations. We start by treating hydraulic conductivity as a two-dimensional, statistically homogeneous random field. For this case, we present a novel analytical formulation of the nonlocal head estimates. Numerical finite element results of the mean field are in excellent agreement with those obtained analytically and by unconditional Monte Carlo simulations. On the basis of numerical results we notice that the head estimator in the vicinity of the well is subject to great uncertainty as its variance peaks at the well location. Conditioning plays an important role in such cases. In field applications, conductivity data (used in our conditioning) are often available at well sites. Hence, we further consider the effect of conditioning precisely at the well location. We solve moment equations by our nonlocal finite element methodology and find that the conditioning at the well dramatically decreases head variance. The agreement with the conditional Monte Carlo simulations is excellent.

In order to improve our understanding of tensiometer measurement physics, we present a concept of tensiometry, analyze the results of laboratory and field infiltration tests in fractured basalt, and compare the laboratory experimental data with a numerically simulated response of tensiometers in a fractured-porous medium. We show that the water pressure in the most conductive hydraulic component of the medium (at the time of measurement) primarily affects the tensiometer gauge-pressure: during imbibition, the pressure measured by the tensiometer represents the fracture water pressure, whereas during drainage, it represents the matrix water pressure. During drainage, the measured water pressure is representative of average rock saturation; during imbibition, however, even a small increase in fracture saturation leads to a substantially higher tensiometer pressure. Thus, tensiometer measurements can exhibit significant extrinsic hysteresis even without taking into account the intrinsic hysteresis of the unsaturated hydraulic characteristics of the matrix and fracture. Because of the complex three-dimensional, channelized preferential water flow, local water pressure measurements using tensiometers are of limited use for the evaluation of hydraulic gradient and water flux in fractured rocks on the field scale. The tensiometer measurements can provide only a limited understanding of the water travel time and the fracture-matrix interaction in fractured rocks, and should be supplemented by other types of measurements under field conditions.

As is common in the literature, the natural log permeability of the soils is taken to be a random, multivariate Gaussian function of space. The mean (expectation) of this function is constant and its fluctuations about the mean are statistically homogeneous and isotropic with constant variance and autocorrelation scale. The wetting front is allowed to diffuse in accord with Richards' equation of flow in a partially saturated soil. The infiltrating water is labeled with a passive tracer, the 50% concentration contour of which is taken to indicate the position of the wetting front. The variogram of the contour is introduced to characterize the length and width of the fingers. Results show that whereas mean finger length grows at a nonlinear rate that diminishes monotonically with time, mean finger width remains constant in time. Both mean finger growth rate and mean finger width increase with the variances and correlation scale of permeability.

In this context random fields of hydraulic conductivity are often assumed to be multivariate log normal, and as such fully described by their ensemble mean, variance, correlation length, and correlation function. It is also common in stochastic subsurface hydrology to treat random fields hydraulic conductivity as statistically homogeneous by assuming that these statistical parameters are constant. However, there is growing, albeit controversial, evidence that fluid flow and solute transport in geologic media exhibit multiscale behavior on distance scales ranging from meters to at least 100 km. These experimental observations suggest that statistical parameters of hydraulic conductivity, such as correlation length and variance, vary with the observation scale. Consequently, it was proposed to view hydraulic conductivity as a random fractal, which can be represented as a hierarchy of mutually uncorrelated homogeneous fields. Less is known about variations of hydraulic conductivity with the observation scale. In this chapter we address this question by developing an expression for the equivalent hydraulic conductivity of a box-shaped porous block, embedded within such a multiscale hydraulic conductivity field. Using this expression we rigorously show that hydraulic conductivity varies with the observation scale in a manner conjectured earlier by S. P. Neuman. In particular, as the observation scale increases, hydraulic conductivity increases in three dimensions, remains the same in two dimensions, and decreases for one-dimensional flow.

The evidence of scale effect is commonly based on (1) single-site, single-technique, (2) single-site, multitechnique, and (3) multisite, multitechnique approaches. Among the major conceptual problems of identification of scale effect is the difficulty quantifying the support scale for a variety of hydraulic testing techniques. Using the example of a highly heterogeneous alluvial aquifer in the Neckar River valley (Horkheimer Insel site, Germany), general guidelines for screening of field data are proposed. These guidelines are applied to the analysis of several compilations and original studies of aquifers in crystalline, argillaceous, and carbonate rocks, and in clay, till, sand, and gravel in search of scaling relationships in hydraulic conductivity. It is shown that the laboratory data on hydraulic conductivity in all types of consolidated and unconsolidated rocks are often biased toward the lower end due to problems of sampling and laboratory analysis. In addition, commonly presented in situ data from borehole tests require critical technical screening. Analysis indicates that both conceptual and technical problems obscure evidence and quantification of a possible scale effect in hydraulic conductivity. Although tremendous amounts of data are collected and published, a need still exists for systematic and conclusive analysis of these data.

In this modified formulation, the material derivatives are written in terms of modified velocities. These are the velocities at which the various phase and component variables propagate in the domain, along their respective characteristic curves. It is shown that these velocities depend on the heterogeneity of various solid matrix and fluid properties. Accordingly, an extension to the Peclet number is presented that also accounts for governing equations that may be advective dominant with no reference to the fluid velocity or even when this velocity is not introduced. A mathematical analysis proves that for coupled partial differential equations (PDEs), unlike the Eulerian implicit finite difference scheme the MEL method unconditionally guarantees the absent of spurious oscillations. The MEL formulation is demonstrated for a coupled set of PDEs concerning the problem of saltwater intrusion, with heat transfer. A numerical example suggests that the MEL scheme produces better resolution compared to the Eulerian and the Eulerian-Lagrangian ones.

Analysis of aquifer (channel deposit) connectivity, simulation of complex response to a pumping test, and assessment of effective hydraulic conductivity of the system led to a connected network paradigm for the system and exposed potential shortcomings of more conventional paradigms of subsurface heterogeneity. Typical of many alluvial fan deposits, this system contains a significant volume fraction ( approximately 60%) of fine-grained materials, and the primary aquifer units, localized channel sand and gravel deposits, compose only 18% of the system. Although conventional hydrostratigraphic analysis would suggest that the channel facies are not extensively interconnected, in this stochastic model most (>70%) of the channel cells compose one channel domain that fully interconnects, or percolates, in all three dimensions. Simulation of complex response in multiple observation wells to a 24-hr pumping test demonstrated plausibility of the hydrostratigraphic model and connected network paradigm while providing insights into hydraulic processes in a complex aquifer network. Simulated time-drawdown responses at observation well locations were most sensitive to hydraulic properties of the fine-grained, nonaquifer materials. Contrary to conventional leaky aquifer paradigms based on layer-cake models, decreasing K of the aquitard (flood plain) facies increased, rather than decreased, drawdowns at observation points located in aquifer zones that would commonly be assumed to be separate from the channel stratum being pumped. A lowered flood plain K focuses and extends drawdown into more distal reaches of the channel network. Because of the extensive connectivity of channel sediments, effective hydraulic conductivity parallel to the channels (dip direction), k' (sub y) is merely the arithmetic mean. K' (sub x) (strike direction) and K' (sub z) (vertical direction) are both controlled by more complex hydraulics due to circuitous connectivity transverse to the channel orientations. Channel connectivity and K' (sub z) are sensitive to spatial cross correlation between channel and levee facies in the geostatistical spatial model, demonstrating that facies juxtapositional tendencies can be hydrologically significant.

The proposed method applies to a broad class of soils with flow properties that scale according to the linearly separable model of L. Vogel and coworkers, provided that the dimensionless pressure head Psi has a near-Gaussian distribution. Upon treating Psi as a multivariate Gaussian function, we obtain a closed system of coupled nonlinear differential equations for the first and second moments of pressure head. We apply this Gaussian closure to one-dimensional steady-state unsaturated flow through a randomly stratified soil with hydraulic conductivity that varies exponentially with alpha Psi where Psi = 1/alpha Psi is dimensional pressure head and alpha is a random field with given statistical properties. Upon disregarding correlation between alpha and Psi , we obtain good agreement between Gaussian closure and Monte Carlo results for the mean of Psi over a wide range of parameters; the agreement between variances is good far from the soil bottom where pressure head is prescribed, but not as good near the bottom boundary. We expect that the latter problem will be remedied once we account for correlation between alpha and Psi . Our solution provides considerable insight into the analytical behavior of the stochastic flow problem.

However, it may contribute significantly to spread the pressure decline and enlarge the land settlement bowl around the field. Moreover, it may continue to compact, and hence produce additional subsidence, for a long time after the field abandonment. The dynamics of waterdrive depletion, and related compaction, are primarily controlled by the aquifer extent and its rock hydromechanical properties for any given field pumping program. After production has been completed water progressively floods the reservoir with a moving water-gas interface until a stable equilibrium is ultimately achieved. The process of residual waterdrive depressurization and concurrent reservoir repressurization is a nonlinear one, where nonrecoverable sediment compaction exerts an important influence on the overall occurrence. A nonlinear finite element model to predict land subsidence over a depleted gas field and the associated waterdrive is developed and applied to the gas reservoir of Dosso degli Angeli, Ravenna, Italy. Numerical results show that the waterdrive compaction accounts for two-thirds of the maximum land subsidence of more than 30 cm recorded in 1992 at the well shutdown and suggest that a residual land settlement of almost 10 cm is to be expected by the year 2042 over the two areas of Porto Garibaldi and Casal Borsetti, located a few kilometers south and north of the field, respectively.

We first define the data needed to solve an inverse problem in hydrogeology, then describe the numerous approaches that have been developed over the past 40 years to solve it, emphasizing the major contributions made by Shlomo P. Neuman. Finally, we briefly discuss fitting processes that start by defining the unknown field as geological images (generated by Boolean or geostatistical methods). The early attempts at solving the inverse problem were direct, i.e., the transmissivity field was directly determined by using stream lines of the flow and inverting the flow equation along these lines. Faced with the poor results obtained in this manner, hydrogeologists have tried many different ways of minimizing the balance error representing and integral of the mass-balance error for each mesh for a given transmissivity field. These attempts were accompanied by constraints imposed on the transmissivity field in order to avoid instabilities. The idea then emerged that the unknown field should reproduce the local observations of the pressure at the measurement points instead of minimizing a balance error. Second, it should also satisfy a condition of plausibility, which means that the transmissivity field obtained through the inverse solution should not deviate too far from an a priori estimate of the real transmissivity field. This a priori notion led to the inclusion of a Bayesian approach resulting in the search for an optimal solution by maximum likelihood, as expounded later. Simultaneously, the existence of locally measured values in the transmissivity field (obtained by pumping tests) allowed geostatistical methods to be used in the formulation of the problem; the result of this innovation was that three major approaches came into being: (1) the definition of the a priori transmissivity field by kriging; (2) the method of cokriging; (3) the pilot point method. Furthermore, geostatistics made it possible to pose the inverse problem in a stochastic framework and to solve an ensemble of possible and equally probable fields, each of them equally acceptable as a solution.

A landscape inhabited by a Cycladic civilization on Thera was destroyed; seismic activity, tsunamis, and tephra falls damaged or destroyed cities of a Minoan civilization on surrounding islands. Major cultural changes in the region may have been triggered by this volcanic disaster. The immensity of the eruption is evident from widespread ash deposits in deep-sea sediments of the Aegean, Mediterranean, and Black Seas, as well as in lake sediments in western Turkey. dispersed ash and pumice have been found in coastal deposits and at archeological sites as far east as Cyprus, the Levant, and the Nile delta. Generation of tephra plumes, pyroclastic surges and flows, debris flows, pumice rafts, and tsunamis can be correlated to volcanic activity during four major phases of the eruption. Major eruptions such as the LBA eruption recur on Thera about every 20 ka, as suggested by dates of older eruptions on the island. Volcanic activity since the LBA has been less explosive, with the last eruption in 1950. Manifestations of volcanism and concomitant hazards remain today with fumeroles, seismic activity, hydrothermal springs, and higher concentrations of helium and CO (sub 2) in soils.

This volcano is located at 16 degrees 35'S 70 degrees 52'W, about 70 km east of the major city of Arequipa, Peru. Clearly, AD 1600 Huaynaputina was a major Plinian eruption that locally devastated the communities within 20 km to the west of the volcano and caused considerable damage to the major cities of Arequipa and Moquegua. The eruption left a fall deposit over an area of at least 300,000 km (super 2) in southern and west-central Peru, western Bolivia, and northern Chile. Lima, La Paz, and Arica are the most notable cities to record ashfall. Most of the fall was distributed to the west and north of the volcano. Pyroclastic flows and secondary mass flows were restricted to local drainages and were insignificant in total volume. A minimum estimate for the volume of tephra is approximately 21 km (super 3) , and the magnitude of the eruption is 6 on the Volcanic Explosivity Index. Eyewitness and anecdotal accounts of the events provide a colorful history of the eruption and its effects. Definite precursory activity in the form of strong quakes began on February 15 and the eruption began at about 5 p.m. on February 19, 1600. It lasted two weeks, from February 19 to March 5, during which time constant strong earthquakes and intermittent ash and pumice fall tortured the population and wreaked widespread destruction. The chaos and consternation of the populace are vividly described by both ancient and modern historians. Arequipa suffered extensive damage and required considerable diversion of resources and several years to rebuild. Local destruction of communities occurred due to accumulation of thick fall, earthquakes, and by the passage of pyroclastic and secondary mass flows. Ruins reveal the gruesome details of communities engulfed by the eruption products. Deposition of mass flow material also resulted in damming of rivers. Breaching of dams in the Rio Tambo resulted in flooding and transport of communities, livestock, crops, and fish out to the sea. In addition to the human losses, the loss of farmland, vineyards, crops, livestock, and water resources compounded the significant economic burden on this region; the whole socioeconomic infrastructure of a large part of southern Peru was devastated by the eruption. Remarkably, within a few years the recovery was well on its way. Arequipa and Moquegua were rebuilt and operational, and repopulation of the interior was implemented and farming gradually began again. By 1750 fruit and cereal farming was thriving again, but the wine industry never recovered to its former heights. Several far-field effects have been attributed to the AD 1600 Huaynaputina eruption. Of these, the link between eruption and acidity spikes in both Northern and Southern Hemisphere ice cores is coming more into focus. The Huaynaputina eruption should be considered locally devastating and globally significant and is ranked among the major eruptions of historic times.

Eruptions have occurred every few hundred years from its summit and rift zones, making it the fourth highest lava flow hazard zone on the island of Hawai'i. Although infrequent, Hualalai eruptions produce lava flows that travel down significantly steeper slopes than those of the island's other active volcanoes--Kilauea or Mauna Loa. Continued development on Hualalai's slopes suggests that refinement of its hazard assessment, based on frequency and style of eruption, may now be appropriate. There have been no Hualalai eruptions during modern times on which to assess the style of its eruptions. The most recent eruptions occurred early after contact with explorers from the western world, and scientific descriptions of the events were not made. These eruptions produced three lava flows and two lava flow fields from at least six different vents including en echelon fissure system and reoccupied cones. Information on the style of these eruptions would be invaluable for hazard assessment. On the basis, in part, of their research into historical accounts, previous investigators concluded that one of these most recent flows advanced from its vent more than 15 km to the ocean in less than 1 hr and that similar future flows may pose a hazard to life and property. Our reading of those same accounts finds no lava flow speed or duration information. A more comprehensive search of ships' logs, missionary diaries, travel diaries, maps, early geologic papers, and Hawaiian legends did yield a few more details about the dynamics of these flows and some important questions about their chronology. Of all the events, it is most certain that the Hu'ehu'e flow field occurred in 1801, but dates for the other eruptions are less certain. Most, if not all, of the descriptions of eruptive behavior may also be of the Hu'ehu'e flow field and not the Kaupulehu flow field as others had assumed.

Some of the rift-related basins in southwestern Ethiopia are half-grabens that have not evolved to symmetrical rifts since the initiation of rifting here in the middle Miocene. These basins contain fossiliferous Pliocene-Pleistocene volcaniclastic sediments and volcanic rocks and have been occupied by early hominid populations. The Afar and the Main Ethiopian Rifts are symmetrical, with both margins fully developed. Several paleoanthropological localities, ranging in age from the Quaternary to the Pliocene, were discovered within these rift basins. The discovery of Australopithecus afarensis (the "Lucy" species) at Hadar and Ardipithecus ramidus and Australopithecus garhi in the Middle Awash makes the region the most prolific early hominid area in the world. Many of the known Pliocene-Pleistocene paleoanthropological localities that have given us information about our ancestors are concentrated in the East African Rift System. This is not a coincidence, because the volcanic and tectonic activities that were responsible for the formation of the rift basins and coeval sedimentation created ideal environments for the proliferation of life and the preservation of faunal and floral remains. Volcanic and tectonic activities created plateaus and mountains; most of the sediments in the basins were derived from these topographic highs located within and outside the rift valleys. Volcaniclastic sediments and volcanic ash were responsible for the quick burial and preservation of fossils during diagenesis. Diagenetic processes involving silicification, calcification, zeolitization, felspathization, clay formation and pedogenesis all played roles in fossil preservation in the volcaniclastic sediments. Volcanic rocks interbedded with fossiliferous sediments also provide temporal information about geologic processes, faunal evolution, paleoenvironment, and early hominid behavior and lithic technology.

These events range in character from the development of sequences of extremely narrow growth rings in the Irish bog-oak tree-ring chronologies, to an inferred sudden abandonment of settlement in northern Scotland, an event sometimes termed the "Settlement Crisis" of the European Late Bronze Age. This chapter presents a theoretical analysis of plausible interactions that may have taken place, especially those concerning erupted acid volatiles, the prevailing meteorological situation, soil status, acidification, and human subsistence. It pays particular attention to models and information derived from modern understandings of the nature and impact of volcanic eruptions and emphasizes the desirability of maintaining a healthy skepticism concerning the reality of such linkages.

Several lines of evidence suggest that Toba produced an estimated 10 (super 15) -10 (super 16) g of stratospheric dust and H (sub 2) SO (sub 4) aerosols, and ice-core data and atmospheric modeling indicate a ca. 6-yr residence time for the dense global aerosol cloud. Such a stratospheric aerosol loading is predicted to have caused a "volcanic winter" with possible abrupt regional coolings of up to 15 degrees C (similar to nuclear winter scenarios), and global cooling of 3-5 degrees C (and possibly greater) for several years. Ice-core data suggest that Toba may have contributed to the initial severe cooling of a millennium-long cold event, suggesting involvement of climate feedback responses such as ocean cooling, and increased sea ice and snow cover. Botanical studies and model simulations suggest that the local and regional effects of the predicted post-Toba cooling would have been disastrous for vegetation. Cold-sensitive tropical vegetation would have been almost totally destroyed, and the predicted reduction of early growing-season temperatures by > or =10 degrees C in higher latitudes could have killed most temperate and subarctic forests, with surviving vegetation severely damaged and recovery times taking decades. Global climate models predict that the Toba atmospheric perturbation would have caused severe drought in the tropical rainforest belt and in monsoonal regions. These results constitute a global ecological disaster, with expected reductions in standing crops of plants and animals especially in the tropics. Evidence for these abrupt environmental changes may be detectable in high-resolution palynological records, coral reefs, and ice cores. Genetic studies indicate that sometime prior to ca. 60,000 yr ago humans suffered a severe population bottleneck (possibly only 3,000-10,000 individuals), followed eventually by rapid population increase, technological innovations, and migrations. The climatic effects of the paroxysmal Toba eruption could have caused the bottleneck, and the event might have been a catalyst for the technological innovations and migrations that followed. The present results as to the predicted environmental and ecological effects of the eruption lend support to a possible connection between the Toba event and the human population bottleneck, and suggest that similar bottlenecks among other organisms might be expected at about the same time. Some chimpanzee populations appear to have undergone such a bottleneck ca. 70,000-60,000 yr ago.

Rapid transfer of flow momentum to seawater can generate devastating tsunamis that transmit the lethal effects of an eruption over large distances. Evidence from submarine volcaniclastic deposits around Krakatau volcano indicate that the great 1883 tsunamis were linked in part to pyroclastic flows entering the Sunda Straits during the August 26-27 eruption. A second hazard component of this process involves the ability of upper, dilute parts of pyroclastic flows or surges to travel over the sea surface for tens of kilometers and reach distal coastlines. During the 1883 Krakatau eruption, hot flows were able to traverse 40 km of the Sunda Straits to reach the southeast coast of Sumatra and kill approximately 2,000 people. Recognition of these hazards is important in areas where pyroclastic flows may be discharged into the sea.

The well is represented by a line sink that produces water at a deterministically prescribed constant rate Q for unit aquifer thickness. The log hydraulic conductivity, Y = lnK, of the aquifer is multivariate Gaussian, statistically homogeneous with a Gaussian spatial autocorrelation function. We develop an analytical solution for the variance of hydraulic head as a function of dimensionless vertical and horizontal locations within the aquifer, variance sigma (sub gamma ) (super 2) of Y and dimensionless ratios between the principal spatial correlation scales. Our analysis is based on the non-local theory first proposed for steady state and transient flows in bounded, randomly heterogenous media by Neuman & Orr (1993), Neuman et al. (1996), Guadagnini & Neuman (1999a,b) and Tartakovsky & Neuman (1998, 1999). In particular, we develop and solve analytically recursive closure approximations of the governing non-local moment equations to second order in sigma (sub gamma ) by means of an appropriate Green's function. We evaluate our analytical solutions by means of Gaussian quadratures for the special case of the isotropic Y field.

A Monte Carlo analysis was performed to investigate the effects of fracture orientation, length scale, and other fracture network properties on effective porosity estimates derived from tracer tests in fractured rock with low matrix permeability. Effective flow porosity estimates obtained from tracer tests are often significantly larger than those deduced from observed fracture spacings and apertures in borehole logs and cores. This raises the concern that effective porosities derived from tracer tests could lead to under-prediction of contaminant concentrations and over-prediction of travel times. One possible explanation for this discrepancy is that the flow heterogeneity resulting from the aquifer's fracture network may bias porosity estimates high. This possibility was investigated by conducting 2-D simulations in which (1) several realizations of a continuum hydraulic conductivity field representing a fracture network with specified geostatistical properties were randomly generated, (2) a weak-dipole flow field was solved for each realization, (3) tracer breakthrough curves were obtained for each flow field using a particle-tracking algorithm, and (4) effective flow porosities were estimated from the mean travel times; these were compared to the "known" flow porosity which was fixed for all simulations. Several fracture network statistical properties were systematically varied to determine their effect on tracer travel times and mass recoveries.It was shown that high effective porosity estimates and low tracer mass recoveries were common for fracture networks in which fractures were not well aligned with the axis intersecting the two wells. These results suggest that effective porosities derived from tracer tests should be used cautiously and may be nonconservative in predictive models. Although the simulations were conducted in 2-D, we believe that the concepts and implications readily extend to 3-D fractured rock systems.

Colloid-facilitated transport has been implicated as a significant mechanism by which a barely detectable amount of plutonium migrated at least 1. 3 km over the past 30 years in Pahute Mesa groundwater at the NTS. Using the FEHM flow and transport code's new Generalized Dual Porosity Model (GDPM) capability in conjunction with geostatistical simulations of hydrogeologic attribute heterogeneity, we simulate the migration of source contaminants in the fractured volcanic aquifers of Pahute Mesa. The mixed equilibrium/kinetic reactive transport model accounts for the processes of solute-colloid reactions, colloid filtration, matrix diffusion, and solute-mineral reactions in the matrix and fractures. Kinetic reaction rates for the plutonium-colloid sorption reactions are derived from model fits to laboratory batch and column experiments. Attachment and detachment rates for colloids onto fracture surfaces are derived from both column experiments and field-scale tests. Constants for equilibrium reactions between solutes and immobile minerals are derived from thermodynamic databases and from sorption experiments involving actinides and volcanic tuff. First, the model is tested with a laboratory column experiment involving colloids and plutonium. Then, it is extended to the field scale to investigate recent observations of plutonium migration. Starting with a calibrated flow model on an 8X11 km (super 2) domain, the reactive transport simulations are conducted in an embedded, high resolution 3X3 km (super 2) subdomain populated with the heterogeneous attributes. Sensitivity analyses show that the model predictions are most sensitive to the parameters governing plutonium-colloid interaction, colloid filtration, and solute reactions with fracture minerals. Therefore, simulations involving distributions of uncertainty in governing transport parameters and multiple realizations of permeability are integrated to assess migration processes for actinides in this complex system. With this model, the appearance of plutonium at observation wells 1.3 km from the source can be explained when kinetic plutonium-colloid reactions are considered in the model.

Pu was detected 1.3 km from the BENHAM test in two wells, a lava formation located near the depth of the blast, and a welded tuff aquifer located some 500 m above the detonation point (Kersting et al., 1999). The BENHAM test produced a spherical cavity roughly 200 m in diameter. A cylindrical, rubblized, chimney extending from the working point of the test into the upper welded tuff aquifer formed as rock above the cavity collapsed. At the bottom of the cavity, a puddle of melted rock formed to an estimated depth of 35 m. A puzzling question arises as to how Pu could have migrated from the test site to two distant wells located in aquifers that apparently are out of communication with one another. To investigate this question, the computer code FLOTRAN (Lichtner, 2000), which couples transient, non-isothermal flow and reactive transport, was used to model Pu migration from the BENHAM underground test. A mechanistic model for glass dissolution is incorporated in the model to describe the release of Pu from the melt glass. FLOTRAN accounts for changes in redox state, pH, carbonate and other species concentration over time and distance as the ambient fluid reacts with the melt glass and minerals in the chimney and surrounding host rock. Two-dimensional calculations predict strong coupling between thermal, hydrologic, and chemical processes at the BEHNAM test. The thermal perturbation produced by the explosion and subsequent cooling of the melt glass results in the formation of convection cells within the chimney. As convection becomes more vigorous, fluid is pushed vertically by buoyancy forces into the overlying tuff aquifer carrying along with it dissolved and colloidal-form Pu. Once Pu reaches the upper aquifer it rapidly migrates horizontally through the fractured tuff aquifer as a consequence of the ambient flow field. As the melt glass cools, the convection cells collapse, resulting in a pulse release of Pu to both the upper and lower aquifers.

The tuff sample is from a surface outcrop of the Calico Hills formation, which lies below the proposed location for a high-level nuclear waste repository, at Yucca Mountain, NV. The sample is a devitrified tuff composed mainly of zeolites, and having clinoptilolite (approximately 70%), mordenite, and opal CT as major constituents. Sample preparation consisted of pulverizing the sample and baking it in vacuum at 640 K for 8 hours. The sample was loaded consecutively to saturations 0%, 5% and 10% by weight, and sealed. QENS measurements were made at each saturation at five temperatures in the range 200 K to 400 K. Diffusional motion is observed and seen to increase with both saturation and temperature. The data are analyzed to determine the rotational diffusion coefficient, the translational diffusion coefficient, the amount of water that is immobile (internal vibrations only), bound (free to rotate, but not to translate), and the amount of water that is free to translate. The results correlate well with those of similar studies on pure zeolites and clays, providing a short time scale reference point for water mobility in the vadose zone between the proposed Yucca Mountain repository and the water table below it.

The great diversity of present-day planetary objects apparently formed from a relatively homogeneous solar nebula, the composition of which is preserved in solar surface material. A variety of ultrapure materials will be exposed to the solar wind for 2 years and returned in Sept 2003 for analysis in terrestrial laboratories. Studies during Apollo by the U. Bern demonstrate the basic feasibility. Materials have been selected based on purity, surface cleanliness, and projected analyzability. For measurement of the isotopic compositions of O , N and selected other elements where pure materials are not available, an electrostatic lens (Concentrator) has been built at LANL which will provide a X20 enhanced fluence over 25 cm2 for elements lighter than Mg. The three types of solar wind (coronal hole, low speed interstream, and coronal mass ejections) will be sampled independently. Present data from spacecraft instruments indicate that high first ionization potential elements show different degrees of elemental fractionation in the 3 types of solar wind, but there is no evidence for isotopic fractionation. Genesis will greatly improve knowledge of these fractionations allowing improved insight into the origins of the different solar wind types, thus enabling corrections back to a common photospheric reservoir. All corrections must lead to the same photospheric composition, providing an important internal check on the accuracy of the derived abundances. The other major control on data quality is automatically provided by being a sample return mission: important results can be replicated, on different collector materials and by independent analytical techniques. Both before and after launch, Genesis materials will be handled in a state of the art clean room at the Johnson Space Center. Genesis samples will be available to the international science community beginning in 2004. Development of advanced analytical facilities open to external users to aid in the analyses will begin in 2001.

This spatial relationship suggests that the heat supply for metamorphism was the associated granitic intrusives. Available geochronologic constraints of selected granitoids imply intrusion emplacement was temporally separated. However, mineral textures suggest a complex thermal history. To gain insight into the controls on this "regional-contact metamorphism", a series of two and three-dimensional heat and mass transport calculations were used to model thermal histories for various intrusion and fluid flow scenarios. Intrusion of a single 2 km thick sill-like pluton emplaced at 12 km depth (geologic constraints based on field studies) does not produce sufficiently high peak temperatures in the aureole ( approximately 590 degrees C) nor mineral zones of sufficient width to match observations (sil zone). In addition, heating and cooling rates of the highest grade rocks are extremely rapid. Close to the intrusion, temperatures cool below 550 degrees C ( approximately st in) in <60,000 yrs. For comparison, intrusion of a 5 km thick pluton causes peak temperatures in the aureole to reach approximately 620 degrees C; temperatures remain above 600 degrees C ( approximately sil in) for approximately 150,000 yrs and above 550 degrees C for approximately 390,000 yrs. Alternatives to the single intrusion scenario are explored for systems which result in higher peak temperatures for longer time periods. For example, simultaneous intrusion of five plutons separated by approximately 4 km (from field observation) causes maximal aureole temperatures of approximately 660 degrees C between plutons. Cooling is slowed for regions between plutons; temperatures remain above 650 degrees C for approximately 100,000 yrs, above 600 for approximately 250,000 yrs and above 550 degrees C for approximately 1.4 Ma. The temporal and spatial relationships of thermal histories provided by each scenario affect the distributions of isograds, mineral textures and scales of mineral equilibration. These data can then be used in conjunction with field relations to provide constraints on the regional contact metamorphism in NW Maine.

In the particular case of precipitation, a new layer may be formed at the interface of the two matrixes due to pore filling by precipitates. Such layers can be hard with low permeability, and commonly accumulate a large variety of inorganic and organic chemicals. These phenomena suggest possible approaches to solve waste disposal and environmental contamination problems. A combination of mathematical modeling and radio tracer diffusion experimental study on the formation of self-forming layer due to transport of Fe3+ in the layered acidic jarosite and alkaline fly ash has been conducted, with particular emphasis on the impact of such self-formation layer on the transport and reactivities of the system. Our results indicate that the self-forming layers at the interface of acidic jarosite and alkaline fly ash consists of amorphous ferric oxyhydroxide FeOOH and gypsum CaSO4(2H2O) caused by precipitation reactions among the principal constituents from these two chemically different materials. Our results also indicate that the newly formed layer has low permeability to groundwater and leachate, thus affecting significantly the transport properties of the system. In addition, its chemical reactivity is primarily due to amorphous ferric oxyhydroxide FeOOH, which possesses a strong adsorption capacity for a large variety of cations and anions. As adsorption on FeOOH provides an important sink for environmentally hazardous elements, we have studied this adsorption process using XPS, a surface analytical technique, to study the reaction mechanism between FeOOH substrate and solutes. This type of spectroscopy provides detailed charge transfer assessment between substrate and adsorbates by measuring variations in core level and valence band spectra. It enables close to first principle rationalizations concerning the nature of chemical bonding between solid and solutes from a frontier orbital perspective.

The borehole is one of 6 drilled to investigate seismic hazards at a facility located within the potentially active Pajarito fault zone. Borehole SHB-WETF-2C penetrates approximately 45 ft of unit 4 of the Tshirege Member of the Bandelier Tuff (1.22 Ma; date from Izett et al., 1994). At this depth in the core, tuff is underlain by finely bedded sands, silts, and clays with abundant charcoal. The contact between tuff and sands is horizontal, and no disruption of layering in the bedded sediments is evident. Radiocarbon dates obtained from charcoal in this interval give stratigraphically concordant dates of 8030+ or -50, 7500+ or -50, and 6280+ or -50 radiocarbon years BP at depths of 56.5, 49.0, and 46.5 ft respectively. From a depth of approximately 60 ft to total depth of the borehole (77.5 ft) is a zone of clay-rich breccia near the top of which we identified foliated clays dipping approximately 60 degrees . These foliated clays, examined by petrographic and scanning electron microscopy, show evidence for cataclasis, including weak dimensional preferred orientations of sand-sized grains, well-developed preferred orientations of clay minerals, as well as parallel grooves in clay. Cataclastic lineations are subparallel to the presumed slip direction. We interpret the bedded sediments as fissure fill deposited on top of fault breccia. The 14C dates suggest deposition of the fissure fill following a seismic event at about 8000 yrs ago, documented in paleoseismic trenches on the Pajarito and associated faults. Our results suggest that structures including monoclines, fissures, and small normal faults in the hanging wall of the Pajarito fault, up to several km away from the main trace of the fault, are linked to ruptures on the Pajarito fault. Furthermore, we show that cataclastic fabrics in clay-rich gouge can be identified from cores and distinguished from fissure fill, allowing identification of faults not exposed at the surface.

We have begun by examining a surrogate MgO-brine system with ambient and hydrothermal experiments. In ambient experiments, defined size fractions of MgO pellets are immersed in synthetic brines (solution-solid mass ratios of 24 or 6), and CO2(g) is bubbled through the system. In the high solution-solid mass ratio experiments, surface area dependent reaction rates were measured. In the low solution-solid mass ratio experiments, a solid cake formed in the experimental cells and, consequently, relatively slower reaction rates were observed. A rich suite of salts occur in the solid reaction products, while simple Mg-hydroxy-carbonate dominated MgO alteration. Hydrothermal experiments using MgO pellets with synthetic brine at 150C and 200 bars were undertaken to enhance reaction rates and examine the formation of hydration and carbonation rinds. In MgO-brine experiments with minimal CO2, the reaction product is brucite, with no observable formation of mixed hydroxide and chloride minerals. Brucite rinds on MgO pellets remain highly permeable with large cracks and internal porosity, apparently a consequence of the large volume expansion associated with alteration. An MgO-brine experiment was injected with liquid CO2 of sufficient quantity to carbonate one third of the MgO in the charge. Consumption of CO2 by mineral alteration reactions resulted in a slow pressure decrease in the experimental cell. When the pressure again maintained a constant value, samples of the experimental solution were effectively depleted in CO2 or carbonate. Analysis of the solid reaction products showed a mixture of brucite, magnesite and periclase. Small amounts of anhydrite and a variety of other salts were present, some probably due to precipitation when the experiment was disassembled and the solids and brines were separated. Two distinctive morphologies and clusters of magnesite are present in the experiments. The experimental reactions provide initial constraints on relative mineral stabilities in low to moderate temperature brine aquifer systems with potential for CO2 sequestration.

Tracers used in the tests include halides, fluorinated benzoic acids (FBAs), fluorescent dyes, lithium, transition and rare-earth metals, and polystyrene microspheres. Halides injected at the site include bromide and iodide. Bromide injection began at the start of the test and was thus subject to a strongly transient flow field, while iodide injection began one year into the test, after the flow field approached a steady state. Five different FBAs (2,4-diFBA, 2,6-diFBA, 2,4,5-triFBA, 2,3,4,5-tetraFBA and pentaFBA) are being used; different injection boreholes are tagged with different FBAs to enable determination of cross-hole connections and estimation of transverse dispersion. Three fluorescent dyes (sodium fluorescein, rhodamine WT, and 3-carbomoyl-2(1H)-pyridone) were injected to enable field visualization of breakthrough during the testing phase, and possible plume identification during eventual mineback activities. Lithium is a weakly sorbing cation that has been used as a reactive tracer in saturated-zone transport tests at Yucca Mountain, and was anticipated to exhibit breakthrough in a relatively short time. The transition metals manganese, cobalt, and nickel, and the rare-earths cerium and samarium were selected as sorbing tracers, and the polystyrene microspheres were intended to act as surrogates for radiocolloids. The sorption behavior of all of these tracers, as well as that of neptunium, plutonium, and americium, has been studied using laboratory batch-sorption techniques on three rock samples from Busted Butte. Results confirm the non-reactivity of the FBA, halides, and fluorescein. Rhodamine WT and the pyridone derivative exhibit minor sorption, and all of the metals and radionuclides show significant sorption (Li0.02 M). This information can be used for understanding stabilization and immobilization of these actinides at potential repository sites where groundwater contains relatively high concentration of salts. Strong sorption of the actinides by colloids in groundwater with lower ionic strength may facilitate transport of radionuclides along potential flowpaths.

It is therefore important to enumerate the retardation processes and predict the sorption behavior of radionuclides in such deposits. As part of on-going hydrologic and geological studies, we have investigated the retardation potential of alluvium with respect to neptunium (Np(V),technetium (as pertechnetate ion, TcO4-), and iodide. Extensive batch and column experiments were carried out to determine the apparent distribution coefficients, Kd (ml/g) of these three radionuclides onto alluvium materials from four different horizons in a Yucca Mountain groundwater. Additionally, we characterized the mineralogical composition of the alluvium samples with quantitative XRD and their particle surface area with N2-BET. We found that 237Np can be adsorbed onto alluvium in variable amounts depending mainly upon the mineralogical composition of the sample but also upon the surface area of the sample. However, the surface area of alluvium primarily depends on the amount of clay and zeolites in the sample further demonstrating the connection between surface area, mineralogy and sorption. The Kd value for 237Np varied from 5 to 500 whereas 99Tc and 129I showed virtually no adsorption potential on alluvium. In comparing batch and column data for 237Np, it was observed that Kd values calculated from column data were several times smaller than those obtained by batch techniques. This result can be attributed to the use of unwashed alluvium fractions in the batch experiments, which tended to contain a significant amount of fine particles such as clays and zeolites, whereas in column experiments, the fine particle fraction was washed away during necessary pre-treatment even though care was taken to minimize this effect. All experiments were conducted under ambient laboratory conditions. Reducing conditions are expected in some of the alluvial flow pathways, therefore, it is important to repeat these experiments under reducing conditions.

At present, the Hijiori HDR system has two reservoirs (a shallow reservoir and a deep reservoir) and four wells (SKG-2, HDR-1, HDR-2a and HDR-3) as shown in Figure 1. The Hijiori multi-reservoir system consists of two injection wells in the artificial reservoirs (SKG-2 into the shallow reservoir, HDR-1 into the deep reservoir) and two production wells, HDR-2a and HDR-3, which also intersect the shallow reservoir. Considering cost performance benefits, a multi-reservoir system is an important technique for the development of HDR. The Hijiori HDR test site is the best field to evaluate characteristics of a multi-reservoir system. Tenma et al. (1996) examined the interference between the shallow and the deep reservoirs using the variation of downhole pressure. As a first step to better understand the behavior of the Hijiori reservoir, we have developed a model of the deep reservoir at the Hijiori HDR test site. To estimate the behavior of the deep reservoir when the injection pressure is varied, we used Gangi's Bed-of-Nails model and Lomize's friction factor. In this paper, we report on the modeling of the deep reservoir, and estimate the productivity of the deep reservoir.

Natural springs and water wells at the site exhibited saline contamination from an unknown source. Several springs emanating from Ogallala Fm. outcrops contribute to stream flow at the site. EM methods were used to bracket the source area of saline water and help identify locations for monitoring wells. Six transects were run in several locations and directions at the site from the ground surface at spacings of 10, 20, and 40 meters using the Geonics EM34-3 meter. Reconnaissance soundings were made at multiple separations to screen individual borehole locations. Additional down-hole readings were made using the Geonics EM39 meter to determine vertical changes in soil conductivity in two contrasting zones. Transect data were used to produce simple models of vertical conductivity changes. Over most of the site, the typical conductivity profile is that of a nonconductive surface layer overlying a more conductive (saturated) layer. At the upland sites, the former represents unsaturated Ogallala deposits, while the latter represents the top of the saturated zone, where increases in modeled conductivity correlate to increases in water and chloride content. Conductivities in the unsaturated Ogallala deposits were typically very low, less than 25 mS/m, while conductivities in saturated soils in background locations varied from 50 to 80 mS/m. In areas where saline contamination was found (and verified with later chemical analysis), conductivities were very high, up to 300 mS/m. A distinct high-salinity source area was identified in the oil field; further investigations of boreholes and wells in that area are ongoing.

Challenges to characterizing ground-water occurrence include sparsity of wells in the ranges and stratigraphic variability of the basin-fill aquifers over short distances. Challenges to determining ground-water movement include the sparsity of water-level data in the ranges, the difficulty in analyzing the water balance owing to infrequent but intense runoff events, and the uncertain role of playas in discharge. Challenges to describing ground-water quality include the sparsity of data for the ranges and the impact of mixing with geothermal waters. Challenges to interpreting geologic controls of hydrologic phenomena include the sparsity of wells in the ranges and assessing the role of any Quaternary-lake history in shaping the modern hydrogeologic system. Some of these challenges can be overcome by (1) utilizing alternative data sources, such as mining and petroleum exploration wells in the ranges, (2) collecting long-term data for various water-balance parameters, and (3) modeling the hydrogeologic and hydrochemical system(s).

To use these models, the analyst inevitably requires some input from experts. Equally, to understand the implication of the models, the analyst needs to explore their sensitivity to the inputs and uncertainty analysis is a key tool in doing this. In this paper, the interplay between these two aspects of the use of accident consequence models is considered, paying particular attention to issues and limitations that require further research in the coming years.

The evaluation of all possible mitigation strategies for FG are reported in the first part of this paper. The first part of the study identified dilution, supernatant liquid removal, heating, use of inert gas in the dome space, and horizontal jet mixing as the leading candidates for mitigating the FG hazard. The models used in the analyses of five mitigation strategies are reported in the second part of the paper. Using these models, analyses were performed for five FG double-shell tanks: AW-101, AN-103, AN-104, AN-105, and SY-102, which are known as Facility Group I (FG-1) tanks. The mitigation of an FG hazard by using an inert gas in the dome space of FG-1 tanks was found to mitigate the FG hazard for all FG-1 tanks if the released gas mixes well in the dome space. However, it does not eliminate the FG hazard during plume releases completely. The horizontal jet mixing strategy reduces the gas inventory, provides a method of controlling the gas release volume and frequency, and mitigates the FG hazard. Removing supernatant liquid would eliminate the FG hazard in Tanks AN-104, AN-105, and AW-101. Mitigation by heating would be recommended only in Tank AW-101. Dilution mitigates the FG hazard in Tanks AN-103, AW-101, and SY-103. The FG hazard exists in one or more of the FG-1 tanks during implementation of all of these mitigation strategies.

The basis for the standard comes from data collected from relatively pure plutonium metal and oxide. However, much of the material in the Department of Energy complex currently awaiting packaging for long-term storage is not pure metal or oxide but also contains chloride salts, including NaCl, KCl, CaCl sub(2), and MgCl sub(2), which must be taken into consideration when making decisions regarding pre-packaging processing. The DOE-STD-3013-96 standard is currently undergoing revisions to include these considerations, specifically a lowering of the temperature of pre-packaging calcination from 950 to 800 degree C. Calcining impure plutonium residues at 800 degree C may or may not be sufficient to reduce the water content of the residue to below 0.5 wt%, a criteria deemed important to prevent the over-pressurization of long-term storage containers. This paper summarizes the literature describing the dehydration and rehydration of PuO sub(2), NaCl, KCl, CaCl sub(2), and MgCl sub(2) and experimental results from impure oxides containing chloride salts, and applies this information to the direct problem of stabilizing impure plutonium oxide residues for long-term storage. Overall, the literature data available is not sufficient to unequivocally guarantee the stabilization processing and packaging conditions necessary to meet the 0.5 wt% water content criteria of DOE-STD-3013-96. It can be concluded that studies and measurements performed on individual components are not an adequate indication of overall hydration behavior of mixtures. In order to minimize the amount of water adsorbed for samples containing chloride salts, we recommend salt residues be calcined at 850 degree C for at least 2 h, they be sealed in an approved storage container as soon as possible after calcination, and the moisture content of the glovebox atmosphere not exceed 35% relative humidity.

We evaluated densities of deer mice (Peromyscus maniculatus), plant cover and biomass, and terrestrial arthropod biomass at 2 sites in the southwestern United States to identify factors that may affect the seroprevalence rate of SNV within a rodent population. Seroprevalence differed significantly between years. Although interaction of deer-mouse density, plant cover and biomass, and arthropod biomass was not a strong predictor of seroprevalence (R super(2) = 0.64, P = 0.04), we observed a significant contribution to a repeated-measures model by deer-mouse density (P = 0.02). Our data suggest that as rodent density increases, so does the seroprevalence rate within that population. Although not significantly correlated, we observed the lowest levels of arthropod biomass when seroprevalence was highest. Based on our results, evaluating changes in habitat quality and incorporating measurement of local ecological variables with studies of fluctuations in rodent density may aid in predicting human outbreaks of hantavirus disease.

Pinon pine is used for firewood, fence posts, and building materials and is a source of nuts for food - the seeds are consumed by a wide variety of animals and are also gathered by people in the area and eaten raw or roasted. This study investigated the (1) concentration of super(3)H, super(137)Cs, super(90)Sr, super(tot)U, super(238)Pu, super(239,240)Pu, and super(241)Am in soils (0- to 12-in. [31 cm] depth underneath the tree), pinon pine shoots (PPS), and pinon pine nuts (PPN) collected from LANL lands and regional background (BG) locations, (2) committed effective dose equivalent (CEDE) from the ingestion of nuts, and (3) soil to PPS to PPN concentration ratios (CRs). Most radionuclides, with the exception of super(3)H in soils, were not significantly higher (p < 0.10) in soils, PPS, and PPN collected from LANL as compared to BG locations, and concentrations of most radionuclides in PPN from LANL have decreased over time. The maximum net CEDE (the CEDE plus two sigma minus BG) at the most conservative ingestion rate (10 lb [4.5 kg]) was 0.0018 mrem (0.018 mu Sv); this is far below the International Commission on Radiological Protection (all pathway) permissible dose limit of 100 mrem (1000 mu Sv). Soil-to-nut CRs for most radionuclides were within the range of default values in the literature for common fruits and vegetables.

The operation is performed in a plutonium glovebox. Presented in this paper are results from the study of the hydrothermal oxidation of plutonium and americium contaminated organic wastes. The use of thermal liquefaction, via pyrolysis, to prepare solid materials for hydrothermal processing was tested and compared to the pumping of slurries of small particle sized solids (ion exchange resin). Experiments show that the hydrothermal process converts greater than 99.9% of the organic component to CO sub(2) and H sub(2)O, with 30 wt% H sub(2)O sub(2) as an oxidant, at 540 degree C and 46.2 MPa. The majority of the actinide component forms insoluble products that are easily separated by filtration. A titanium liner in the reactor and heat exchanger provides corrosion resistance for the oxidation of chlorinated organics.

The TWA concentrations of the hydrocarbons detected by CST/GC analysis were summed for comparison with the TWA concentration obtained from the direct-reading PID. Based on linear regression between the log TWA concentrations of the two sampling methods, the data were highly correlated (r super(2) = 0.95). Since the solvents had effects that may be considered additive, threshold limit values (TLVs registered ) for mixtures were developed using American Conference of Governmental Industrial Hygienists formulas to evaluate solvent exposure. The logs of the TLV mixture data from the sampling methods were highly correlated (r super(2) = 0.94). Based on the linear regression analyses, the response of the portable PID was highly correlated to the CST/GC results for hydrocarbon mixtures encountered during various painting tasks. Due to the short duration of tasks, highly fluctuating exposures, and complexity of the mixtures, the PID may provide the most cost-effective, detailed exposure assessment for solvent mixtures.

Here we describe a method for making libraries so large that the complete diversity cannot be accessed using traditional phage technology. This involves the creation of a primary phage scFv library in a phagemid vector containing two nonhomologous lox sites. Contrary to the current dogma, we found that infecting Cre recombinase-expressing bacteria by such a primary library at a high multiplicity of infection results in the entry of many different phagemid into the cell. Exchange of VH and VL genes between such phagemids creates many new VH/VL combinations, all of which are functional. On the basis of the observed recombination, the library is calculated to have a diversity of 3 x 10 super(11). A library created using this method was validated by the selection of high affinity antibodies against a large number of different protein antigens.

The creation of bacterial biosensors is hampered by a lack of information about the genetic systems that control production of bacterial enzymes that metabolize pollutants. We have attempted to overcome this problem through modification of DmpR, a regulatory protein for the phenol degradation pathway of Pseudomonas sp. strain CF600. The phenol detection capacity of DmpR was altered by using mutagenic PCR targeted to the DmpR sensor domain. DmpR mutants were identified that both increased sensitivity to the phenolic effectors of wild-type DmpR and increased the range of molecules detected. The phenol detection characteristics of seven DmpR mutants were demonstrated through their ability to activate transcription of a lacZ reporter gene. Effectors of the DmpR derivatives included phenol, 2-chlorophenol, 2,4-dichlorophenol, 4-chloro-3-methylphenol, 2,4-dimethylphenol, 2-nitrophenol, and 4-nitrophenol.

The distributions of event locations suggest that all six hydraulic fracture were oriented at N78 degrees E, in line with the major principal stress orientation in the field. Spatially, the microseismicity generally exhibited asymmetric behaviour with preferential growth to the east of the treatment wells (symmetry varying from 1:1 to 4.5:1). Only in two instances could the fracture be considered as symmetric, however, temporal growth patterns, as identified in the source parameter distribution were highly asymmetric. The fractures were constrained in depth to the perforation zones and varied in overall length from 1300 ft. to 2200 ft. Observed terminations in microseismic activity were considered to be related to crosscutting structures that altered or impeded fracture wing growth. Differences in apparent stress drop distributions suggested that these parameters can be used to outline differences in fracture behaviour and to define regions of the fracture where fracture growth does not necessarily contribute to the development of a propped zone. The results further suggest spatial variations in microseismicity, correlated with the treatment histories, can provide more information on the dynamics and heterogeneities associated with fracture growth.

Elastic numerical modeling is an essential tool to develop that understanding. While 2-D elastic modeling is in common use, 3-D elastic modeling has been too computationally intensive to be used routinely. Recent advances in computing hardware, including commodity-based hardware, have substantially reduced computing costs. These advances are making 3-D elastic numerical modeling more feasible. A series of example 3-D elastic calculations were performed using a complicated structure, the SEG/EAGE salt structure. The synthetic traces show that the effects of shear wave propagation can be important for imaging and interpretation of images, and also for AVO and other applications that rely on trace amplitudes. Additional calculations are needed to better identify and understand the complex wave propagation effects produced in complicated structures, such as the SEG/EAGE salt structure.
