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.
