Students should be probed for understanding, reasoning, and critical thinking abilities rather than their ability to return memorized facts.. The assessment of the Department of Energy's pilot program, Adventures in Supercomputing (AiS), offers one example of assessment techniques developed for learner-centered curricula. The goals and objectives that are central to student learning in the Adventures in Supercomputing program [http://anarchy.k12.ames.ia.us/AiS/national] involve the acquisition of thinking and problem-solving skills. During the school year, students are involved in a year-long computational science project. To complete the project students employ the following tools: 1) the Internet to aid in researching their topics and communicating with their mentors, 2) computers to develop and test models of the problems, and 3) visualization software to understand their data. From these resources, students must pose hypotheses, devise methods for solutions, conduct appropriate simulations, and draw proper conclusions. The assessment of the AL'S program has employed a variety of methods to collect student data. Methods of assessment used were traditional testing, performance testing, interviews, short questionnaires via email, and student presentations of projects. The data obtained from these sources have been analyzed by a professional assessment team at the Center for Children and Technology. The results have been used to improve the AiS curriculum and establish the quality of the overall AiS program. This paper will discuss the various methods of assessment used and the results.

Various organic sulfur compounds were oxidized with HClO4 solution containing Fe(ClO4)(3), and the amounts of sulfate formed during reaction were measured. The compounds can be grouped into three categories according to their reactivities as follows. (1) easily oxidized ones, i.e. disulfides, for which almost all of the sulfur was converted to sulfate after oxidation, (2) less reactive ones including aliphatic sulfides, aliphatic and aromatic thiols (20-30% of sulfur in these compounds was oxidized to sulfate), and (3) relatively stable ones, i.e. thiophenes and aromatic sulfides, from which no sulfate was formed. Samples of Illinois No. 6 and Bevier coals were also reacted with HClO4 solutions containing increasing concentration of Fe(ClO4)(3). The organic sulfur in these coals could be differentiated into various groups according to their reactivities. C1 IOWA STATE UNIV SCI & TECHNOL,AMES LAB,AMES,IA 50011.

Effects of extraction time, perchloroethylene:coal ratio and artificial weathering were studied to determine their effects on the removal of organic sulfur. The artificial weathering conditions used were found to be too harsh and caused a decrease in the amount of organic sulfur removed, unlike normal weathering conditions. Additional studies were done involving various ligands, and showed that the addition of certain ligands during the process aided in the extraction of organic sulfur from the coal.

Below the calcination temperature of CaCO3 (about 900 degrees C under 1 bar of CO2), complete conversion of the calcium carbonate to calcium sulfide can only be achieved with dolomite. Above the calcination temperature of CaCO3, the conversion to CaS is complete for all three sorbents in about one hour when 10,000 ppm H2S is present in the gas phase. Large particles of limestone thus appear to be a suitable sorbent for high-temperature coal-gas desulfurization (above about 900 degrees C). A mathematical model based on the kinetic information collected in this work predicts the desulfurization performance of a packed or moving bed of limestone particles. Finally, a low-temperature regeneration scheme for the spent sorbent (CaS) in which sulfur can be subsequently recovered as the element is suggested.

A key element of this program is the development of a liquid phase reactor technology which could offer improved economics and operational flexibility over the conventional gas phase reactors. This paper will review the accomplishments of liquid phase methanol technology development at the proof-of-concept (POC) scale unit in LaPorte, Texas and the advancement of this technology to commercial demonstration which has been underway since 1993 under the support of DOE Clean Coal Technology program. The POC facility has recently been upgraded to allow for developing liquid phase reactor technologies for Fischer-Tropsch synthesis and the production of other oxygenate fuels and chemicals from synthesis gas. The upgraded POC unit, now known as the Alternative Fuels development Unit (AFDU), as well as the results of new campaigns that have been conducted al this unit will also be reviewed.

In order to study the effect of coal surface properties and other parameters on the rate of agglomeration, a number of agglomeration tests were conducted in which a batch of coal was agglomerated with either heptane or hexadecane, and the rate of change in the turbidity of the suspension was determined. Two types of bituminous coal were utilized, and the surface properties of each type were varied by exposing the ground materials to air at 150 degrees C for periods ranging from a few hours to 84 hr. Measurements made by means of FT-IR photoacoustic spectroscopy showed that the concentration of oxygen functional groups increased with increasing oxidation time. Furthermore, the apparent rate of agglomeration of either type of coal decreased with increasing oxidation time. Therefore, the rate of agglomeration depended on both the rank of the coal and the extent of oxidation of the coal. The rate was also found to depend on the type of agglomerant and its dosage. While the rate tended to increase in direct proportion to agglomerant dosage, the rate of increase with respect to the dosage fell as the coal became more heavily oxidized.

The feedstocks used for these studies were switchgrass, corn stover, and hybrid poplar. The woody and herbaceous feedstocks were stored in chip piles and bales, respectively, unprotected in an open field for 6 months. At the end of the storage period. biomass samples were taken from the interior of bales and the centers of chip piles for pyrolysis studies. The materials were ground to pass -20/+80 mesh and dried to less than 10% moisture content before pyrolyzing in the fluidized bed reactor. Pyrolysis was conducted at 500 degrees C and with less than 0.4 s. vapor residence time. Total liquid yields were as high as 66% for the hybrid poplar and as low as 58% for the corn stover. Moisture content of the oils was between 10% and 13%. Gas and char/ash yields were 10-15% and 12-22%, respectively. The char/ash yields were feedstock dependent, but storage influence was significant for only the corn stover feedstock. Gas and liquid yields were not influenced by storage time. The oils were highly oxygenated and had higher heating values (HHV) of 23-24 MJ/kg that decreased slightly with storage time for all the feedstocks except the switchgrass. The oils, as currently produced, are high in ash and alkali metals. Ultimately, they will be upgraded and used as boiler and turbine fuels.

Our results demonstrate that the microscopic morphology of the C-60 molecule plays a crucial role in determining the relaxation dynamics. This is a key factor for applications in optical limiting for nanosecond pulses using reverse saturable absorption. We find that the dynamics of the C-60-glass composite occur on long (ns) timescales, comparable to that in solution; thin film samples, by contrast, show rapid decay (<20 picoseconds). These results demonstrate that the C-60-sol-gel glass composites contain C-60 in a molecular dispersion, and are suitable candidates for solid-state optical limiting. Multispectral analysis of the decay dynamics in solution allows accurate determination of both the intersystem crossing time (600 +/- 100 ps) and the relative strengths of the singlet and triplet excited-state cross sections as a function of wavelength from 450-950 nm. The triplet excited-state cross section is greater than that for the singlet excited-state over the range from 620-810 nm.

However, because of availability and low cost, testing in nonfusion facilities (e.g., fission reactors and laboratory experiments)serves a critical role in blanket research and development (R&D) and reduces the risks and costs of the more complex and expensive fusion experiments. A comprehensive analysis shows that the fusion testing requirements for meeting the goal of demonstrating a blanket system availability in DEMO >50% are as follows: a 1 to 2 MW/m(2) neutron wall load, a steady-state plasma operation, a >10-m(2) test area, and a fluence of >6 MW . yr/m(2). This testing fluence includes 1 to 3 MW . yr/m(2) for concept performance verification and >4 to 6 MW . yr/m(2) for component engineering development and reliability growth/demonstration. Reliability and availability analyses reveal critical concerns that need to be addressed in fusion power development. For a DEMO reactor availability goal of 50%, the blanket availability needs to be similar to 80%. For a mean time to recover from a failure of similar to 3 months, the mean time between failure (MTBF) for the entire blanket must be >1 yr. For a blanket that has 80 modules, the corresponding MTBF per module is 80 yr. These are very ambitious goals that require an aggressive fusion technology development program. A number of scenarios for fusion facilities were evaluated using a cost/benefit/risk analysis approach. Blanket rests in the International Thermonuclear Experimental Reactor (ITER) alone with a fluence of 1 MW . yr/m(2) can address most of the needs for concept verification, bur it cannot adequately address the blanket component reliability growth/demonstration testing requirements. An effective path to fusion DEMO is suggested. It involves two parallel facilities: (a) ITER to provide data on plasma performance, plasma support technology, and system integration and (b) a high-volume plasma-based neutron source (HVPNS) dedicated to testing, developing, and qualifying fusion nuclear components and material combinations for DEMO. For HVPNS to be attractive and cost effective, its capital cost must be significantly lower than ITER, and it should have low fusion power (similar to 150 MW). Exploratory studies indicate the presence of a design window with a highly driven plasma. A testing and development strategy that includes HVPNS would decisively reduce the high risk of initial DEMO operation with a poor blanket system availability and would make it possible - if operated parallel to the ITER basic performance phase - to meet the goal of DEMO operation by the year 2025. Such a scenario with HVPNS parallel to ITER provides substantial savings in the overall R&D cost to ward DEMO compared with an ITER-alone strategy. The near-term cost burden is negligible in the context of an international fusion program with HVPNS and ITER sited in two different countries.

This pulse analysis has previously been performed on some bright, long bursts using binned data, and on some short bursts using BATSE Time-Tagged Event (TTE) data. The BATSE Time-to-Spill (TTS) burst data record the times required to accumulate a fixed number of photons, giving variable time resolution. The spill times recorded in the TTS data behave as a gamma distribution. We have developed an interactive pulse-fitting program using the pulse model of Norris et al. and a maximum-likelihood fitting algorithm to the gamma distribution of the spill times. We then used this program to analyze a number of bright, long bursts for which TTS data are available. We present statistical information on the attributes of pulses comprising these bursts.

Specifically, we consider the ''delayed turn-on'' model and the halo beaming model for GRBs. We express the GRB rate from M31 as functions of instrument sensitivities, and the observing solid angle towards M31. We conclude that, with a gamma-ray instrument that is ten times more sensitive than BATSE, delayed turn-on model gives a strong excess of GRBs from M31 but halo beaming model gives only a possible marginal detection in over a year of observations.

The effects of a luminosity function are also discussed. In the context of this model, we find that the sampling depth of BATSE is similar to 160 kpc and the burst peak luminosity is similar to 10(40) erg/s. The distinctive anisotropies predicted by HEM are inconsistent with the 3B data at the 2 sigma level, (i.e., HEM can not be ruled out at the 2 sigma level). Future observations will be capable of placing more stringent Limits. We emphasise that GRB sources born in M31 are almost entirely undetectable by BATSE in this model. We briefly discuss the energy budgets for the bursters and the mechanism of spindown alignment. RP Li, H (reprint author), LOS ALAMOS NATL LAB,MS D436,NIS 2,LOS ALAMOS,NM 87545, USA.

Their 800-km altitude orbits give a field of view to 117 degrees from the zenith. A great many bursts have been detected, usually in coincidence with detections by GRO or other satellites such as PVO or ULYSSES. The directions of the sources can be determined with considerable accuracy from such correlated observations, even when GRO/BATSE with its directional capabilities is not involved. Thus these DMSP data, especially in conjunction with other observations, should be helpful in trying to understand the true nature of gamma-ray bursts.

SO GAMMA-RAY BURSTS - 3RD HUNTSVILLE SYMPOSIUM, PTS 1 AND 2 SE AIP CONFERENCE PROCEEDINGS LA English DT Proceedings Paper CT 3rd Huntsville Symposium on Gamma-Ray Bursts CY OCT 25-27, 1995 CL HUNTSVILLE, AL SP Amer Inst Phys AB We describe a reasonable model of a galactic halo origin of gamma-ray bursts (GRBs). The observed isotropy of GRBs requires fast similar to 10(8) cm s(-1) neutron stars (NSs), with a finite delay period similar to 30 My, before turn on and similar to x10 longer before turning off. The NSs might not be radio pulsars, despite a normal NS magnetic field, similar to 10(12) gauss because of slow rotation from tidal locking in a presupernova binary. The high velocity can be produced from a neutrino rocket effect from anisotropic accretion during the supernova event, which is expected to be aligned with the binary companion. Such a high-velocity NS will capture mass (similar to 10(-5)M.) from a near miss of the companion or from the supernova debris. This mass is x10 the mass required to power an initial soft gamma-ray repeater (SGR) phase for 10(4) y as well as later 10(5) GRBs in 3 x 10(8) y, (assuming one fast NS per 100 years). Following the SGR phase, the disk cools and condenses into a quiescent solar system type disk of grains, rocks and planetoids in similar to 30 My. When the mass of one planetoid exceeds the critical scattering mass, similar to 10(22 to 23) g, some planetoids will be scattered into highly elliptic orbits and break up close to the NS. The orbits of the debris will decay forming a sequence of dense, degenerate, accretion disks, which evolve by radiation cooling and the internal friction of solidification. A disk mass of similar to 10(21 to 22) g results in a thin disk whose Alven radius is close to that of the NS. The velocity of the disk crossed with the strong magnetic field creates high electric fields, large enough to cause vacuum break-down and electron-positron cascades. The displacement current from producing the electric field as well as the break-down current results in the torque of accretion. The break-down cascade process leads to both the characteristic soft spectrum of I-v proportional to v(1/3), observed log-normal distribution of the fluences of the peaks.

The first generation system, GROCSE I, is sensitive down to M(V) similar to 8.5 and requires an average of 12 seconds to obtain the first images of the gamma ray burst error box defined by the BACODINE trigger. The collaboration is now constructing a second generation system which has a 4 second slewing time and can reach M(V) similar to 14 with a 5 second exposure. GROCSE II consists of 4 cameras on a single mount. Each camera views the night sky through a commercial Canon lens (f/1.8, focal length 200 mm) and utilizes a 2K x 2K Loral CCD. Light weight and low noise custom readout electronics were designed and fabricated for these CCDs. The total field of view of the 4 cameras is 17.6 x 17.6 degrees. GROCSE II will be operating by the end of 1995. In this paper, we present an overview of the GROCSE system and the results of measurements with a GROCSE II prototype unit.

The spectra of SGR 1806-20 and the initial spike of the March 5 event can be fitted by a photon-splitting modified spectrum under such a strong magnetic field. A moderate beaming pattern is needed for the emission producing the initial spike of the March 5 event, and the strength of its magnetic field is not well constrained by spectral fitting. An extended emission region over the whole stellar surface is preferred for SGR 1806-20 rather than a localized equatorial region. The intrinsic emission of SGR 1806-20 should be nearly isotropic. The magnetic field near the surface of SGR 1806-20 should be > 10 B-c (B-c = 4.4 x 10(13) G) and its GM/c(2)R is greater than or similar to 0.25.

Further, binding sites for the two families often occur nearby, and there have been a number of indications that members of the two families may bind coordinately. The present study provides evidence that known? binding sires for the two occur with precise geometric restrictions related to the DNA helical repeat unit, that pairs of putative sites following these restrictions are indicative of skeletal muscle-specific transcriptional regulatory regions, and that the geometric relationship can help provide a consistent interpretation for data that has until now been difficult to explain.

The technique has been applied to the study of Al-26 and Be-10 in opal-rich sediments from the North Pacific. The Al-26/Al-27 and Be-10/Be-9 ratios of similar to 3 X 10(-14) and 1 X 10(-7) leached from the sediments are higher than those in the total sediments by factors of 3-10 and 2-3, respectively. The authigenic Be-10/Be-9 ratios are similar to those in deep waters at the study site, pointing to the potential usefulness of the ratios in paleoceanographic studies. The fractions of total Be and Al in the sediment studied that are of authigenic origin average about 40 and 17%, respectively. Estimated Al-26/Al-27 ratios in detrital sediments are less than or equal to 10(-15), low enough to indicate that the source of Al-26 in the ocean mainly comes from atmospheric production. In the study area, the deposition flux of Al-26 is comparable to its atmospheric supply. However, the deposition flux of Be-10 is about threefold higher than the atmospheric input, signifying lateral transport of Be-10 xfrom the open ocean to this area of relatively high particle flux. The Al-26/Be-10 ratio, being insensitive to the oceanic influx of lithogenic particles, may serve as a valuable proxy for paleoproductivity. Both the authigenic and total-sediment Al-26/Al-27 and Be-10/Be-9 ratios decreased significantly at similar to 6 ka, which could reflect an enhanced input of windblown lithogenic particles to the North Pacific. While the enhanced dust input did not significantly alter the deep-water Be-9 concentration, it contributed to the observed increase of authigenic Be-9 flux to the sediment.

Pyrite and marcasite from three Nisku wells have delta(34)S ranging between -35 and +20 parts per thousand CDT; most lie between -35 and -5 parts per thousand CDT. The delta(34)S values of sulfides are heterogeneous within individual thin section-sized samples, varying by as much as 25 parts per thousand. The delta(34)S values increase by up to 50 parts per thousand with increasing well depth in two different Nisku wells, and delta(34)S also increases by up to 15 parts per thousand as grain size increases from 40 to over 100 mu m in individual samples. The appearance of native sulfur is accompanied by an increase of up to 30 parts per thousand in pyrite delta(34)S values. Bulk and ion probe analyses of anhydrite are relatively uniform (delta(34)S = +22 to +30 parts per thousand CDT). The predominately low delta(34)S values of Nisku sulfides indicate bacterial sulfate reduction. Textural relations indicate that Fe-sulfide formation in Nisku carbonates may have occurred by two different mechanisms. Much of the sulfide has delta(34)S values that suggest that it was associated with bacterial sulfate reduction, although most Fe-sulfides did not form until after pervasive matrix dolomitization (depths of 300-1000 m). Other sulfide may have formed later, during deep (similar to 4 km) burial via thermochemical sulfate reduction. The range in delta(34)S values in a single thin section and correlations between pyrite morphology and isotopic values suggest that sulfate reduction was a very localized process, and that the sulfate reduction environment varied considerably on a small scale.

Thermoluminescence age estimates for buried soils beneath the El Cajete pumice, a key stratigraphic marker in the region, range from 48 to 61 ka, and C-14 analyses of burnt logs within volcanic surge beds near the El Cajete vent yield similar ages of 50 to >58 ka. These data conflict with fission-track, Ar-40/Ar-39, and K-Ar ages of 130 to >200 ka, but are supported by recent analyses by electron spin resonance. The results of this study reinforce the need to apply a variety of dating methods when evaluating the age of young volcanic events and support the hypothesis that the El Cajete eruptions were part of a new cycle of volcanic activity in the Valles caldera after an exceptionally long period of quiescence of similar to 460 ka. The new age constraints also suggest a previously unrecognized link between cycles of volcanism and pulses of hydrothermal activity in the caldera, such that hydrothermal outflow appears to decrease significantly following completion of eruptive cycles.

The results cover a horizontal coplanar coil configuration and two frequencies, 7837 Hz and 51250 Hz. The models studied are single or multiple, poor conductors (conductance lower than 0.1 S) embedded in a host rock of high but finite resistivity (5000 Omega m) and overlain by a layer of overburden with finite thickness and low to moderate conductivity (conductance up to 2 S). On the basis of the modelling results, limits of detectability for poor conductors have been studied for the various model structures. The results indicate that the anomaly from a steeply dipping, plate-like conductor will decrease significantly when the conductor is embedded in a weakly conductive host rock and is overlain by a conductive overburden. However, an anomaly is obtained, and its magnitude can even increase with increasing overburden conductivity or frequency. The plate anomaly remains practically constant when only the overburden thickness is varied. Changes in overburden conductivity will cause the plate-anomaly values to change markedly. If the plate conductance is less than that of the overburden, a local anomaly opposite in sign to the normal type of anomaly will be recorded. Another major consequence is that conductors interpreted with free-space models will be heavily overestimated in depth or underestimated in conductance, if in reality induction and current channelling in the host rock and overburden make even a slight contribution to the anomalous EM field. The lateral resolution for the horizontal coplanar coil system was found to be about 1.7 times the sensor altitude. Similarly, the lateral extension of a horizontal conductive ribbon, required to reach the semi-infinite (half-space) behaviour, is more than three times the sensor altitude. Finally, screening of a steeply dipping plate, caused by a small, conductive horizontal ribbon, is much more severe than screening of the same plate by an extensive horizontal layer.

The speed and accuracy of the solution make it practical for use in 2-D or 3-D inversion algorithms. The low-contrast approximation is particularly well-suited to the smooth nature of minimum structure inversion, since complete forward solutions may be computationally expensive. By using this approximate 3-D solution as the forward model in an inversion algorithm, and by constraining the resistivities and polarizabilities along any row of cells in the strike direction to be held constant, we effect a fast 2-D resistivity inversion that contains end corrections. Because the low-contrast solution is inaccurate for cells near the electrodes, we employ a full solution to compute the response of the near-surface when the nearsurface environment is substantially different from the host rock. This response is stored and used in the iterative resistivity inversion in conjunction with the approximate solution. Once an adequate estimated resistivity model has been found, derivatives from this model are used with Seigel's formula to compute the inverse solution to the linear polarizability problem in a single iteration.

Recent advances in field screening technologies present the possibility for adaptive sampling programs-programs that adapt or change to reflect sample results generated in the field. A coupled Bayesian/geostatistical methodology can be used to guide adaptive sampling programs. A Bayesian approach quantitatively combines ''soft'' information regarding contaminant location with ''hard'' sampling results. Soft information can include historical information, non-intrusive geophysical survey data, preliminary transport modeling results, past experience with similar sites, etc. Soft information is used to build an initial conceptual image of where contamination is likely to be. As samples are collected and analyzed, indicator kriging is used to update the initial conceptual image. New sampling locations are selected to minimize the uncertainty associated with contaminant extent. An example is provided that illustrates the methodology.

Geostatistical simulation techniques are being employed to produce numerical models of selected material properties (rock characteristics) in their proper spatial positions. These numerical models will be used to evaluate behavior of various engineered features, the effects of construction and operating practices, and the waste-isolation performance of the overall repository system. The work presented here represents the first attempt to evaluate the spatial character of the rock strength index known as rock quality designation (RQD). Although it is likely that RQD reflects an intrinsic component of the rock matrix, this component becomes difficult to resolve given the frequency and orientation of data made available from vertical core records. The constraints of the two-dimensional study along the axis of an exploratory drift allow bounds to be placed upon the resulting interpretations, while the use of an indicator transformation allows focus to be placed on specific details that may be of interest to design engineers. The analytical process and subsequent development of material property models is anticipated to become one of the principal means of summarizing, integrating, and reconciling the diverse suite of earth-science data acquired through site characterization and of recasting the data in formats specifically designed for use in further modeling of various physical processes.

Temporally changing tracer residence times, reservoir fluid volume, and broadening fluid residence time distributions were measured with two different tracers used simultaneously during both flow tests. The tracers employed were p-toluene sulfonic acid (p-TSA) and sodium fluorescein (NaF1). While p-TSA is considered non reactive, fluorescein degrades at high temperature. Differences in the recovery of the two tracers measured at Fenton Hill suggest the circulating fluid may have increasingly accessed higher temperature flow paths as energy was extracted. However, the reactive and adsorptive properties of fluorescein are not well characterized for the geochemistry of the Fenton hill reservoir, so further study of tracer properties should be conducted before making firm conclusions. Reservoir simulation with GEOCRACK, a computer model that couples thermal deformation with fluid flow and hear transfer, aids in understanding the tracer response with heat extraction. Simulation of non reactive and reactive tracers illustrates how a comparison of these tracers could be employed to characterize fracture surface area and predict thermal breakthrough in liquid dominated, fractured gcothermal reservoirs.

This paper discusses a number of HDR developments in reservoir engineering, seismic science, tracer analyses, and reservoir modeling, and indicates how they might be applied to address hydrothermal issues. It is suggested that the integration of these and other HDR technologies into the geothermal mainstream might significantly contribute to enlarging the potential role of geothermal resources in the energy market of the 21st century.

The production data for 48 wells in the Southeast Geysers were analyzed and the permeability-thickness products determined from the transient production response using the Fetkovich production decline type curve.

The atmospheric noble gases are dominated by dissolved gases introduced with the injection fluid, a mixture of flashed degassed brine and condensate equilibrated with air in the cooling tower. Excess helium, however, represents a primary reservoir fluid and variations in the amount of excess can be used to monitor the changing proportion of injectate in the production fluid. The helium component associated with the reservoir fluid has an isotopic composition (0.70 - 0.76 Ra) implying that similar to 7.5% of the helium in the 1995 Dixie Valley reservoir fluid is mantle-derived The Dixie Valley geothermal field is closely related to the range-front normal fault of the Stillwater Range. Assuming fluid transport along the fault from deeper sources and using a one-dimensional steady-state advection model, the helium content and isotopic composition of the reservoir fluid predicts an average fluid flow rate of virgin fluid from depth of similar to 7 mm/yr. This is significantly less than injectate flow rates within the reservoir estimated from tracer tests (i.e. 5 - 120 m/day).

The point at which the series solution may be truncated is a known function of the problem, and may therefore be readily determined. Furthermore, the functional form of the method is essentially dimension-independent, and implementation of the method requires only minimal modification to an existing dual porosity simulator. Three test cases are presented comparing results from fine grid simulations, Warren and Root simulations, and the new formulation. In each of the three cases presented, excellent agreement with the fine grid simulations is obtained using the new method. The W&R formulation exhibits excessive error throughout the simulated time, first underpredicting outflow rates, and then overpredicting rates. The error using the W&R formulation is largest for 3-D fracture networks, but is large for all cases tested. RP Shook, GM (reprint author), IDAHO NATL ENGN LAB,POB 1625,IDAHO FALLS,ID 83415, USA.

We have developed a tower-based micrometeorological method for measuring gas-phase Hg fluxes over environmental surfaces, and have used this approach to measure Hg degrees fluxes over soils, vegetation, and water surfaces. These fluxes have been combined with modeling results based on measurements of atmospheric Hg concentrations and speciation to quantify the overall flux of Hg between the atmosphere and the ground. These results are compared with a study of the biogeochemical cycle of Hg in the temperate deciduous forest at Walker Branch Watershed in the southeastern United States. Our preliminary results suggest that the largest Hg fluxes in forests involve gas exchange at the air/vegetation interface. Given the magnitude of these fluxes and their level of uncertainty, this forest could act as a net source or sink for atmospheric Hg, indicating the importance of better understanding the role of Hg exchange at the vegetation surface.

In this chapter, we delineate the range of reactions for which supercritical CO2 represents a potentially viable replacement solvent based on solubility considerations and describe the reactors and associated equipment used to explore catalytic and other synthetic reactions in this medium. Three examples of homogeneous catalytic reactions in supercritical CO2 are presented: the copolymerization of CO2 with epoxides, ruthenium-mediated phase transfer oxidation of olefins in a supercritical CO2/aqueous system, and the catalyic asymmetric hydrogenation of enamides. The first two classes of reactions proceed in supercritical CO2 but no improvement in reactivity over conventional solvents was observed. Hydrogenation reactions, however, exhibit enantioselectivities superior to conventional solvents for several substrates. C1 LOS ALAMOS NATL LAB, CHEM SCI & TECHNOL DIV, LOS ALAMOS, NM 87545 USA.

Analytical assessment SO GROUND WATER LA English DT Article ID COMPUTER-PROGRAM; WATER-TABLE; FLOW; CURVES AB Slug interference responses within unconfined aquifers are characterized by an initial wave or ''hump,'' which is followed by a fiat transitional plateau region and then by a declining, recessional limb, segment. The shape and amplitude of the initial wave are primarily controlled by the elastic characteristics (i.e., S) and degree of anisotropy within the aquifer, while transmissivity is the principal parameter affecting the transmission (i.e., arrival time) of the slug interference response. Wellbore storage and delayed-yield effects tend to attenuate the test response. The transitional and late-time recessional segments are significantly influenced by the aquifer's specific yield. In addition, test well/aquifer relationships, e.g., observation well distance, aquifer thickness, and wed depth/aquifer penetration, also strongly affect slug interference characteristics. The sensitivity of the propagated response to test well/aquifer relationships indicates that slug interference tests can be designed to maximize the expected response for aquifer property characterization.

For a chemical barrier to be successful, it must remain permeable and must be immobile. This investigation monitored chemical compositions, hydraulic: conductivity, and iron mobility in laboratory columns and in a two-dimensional tank to determine the viability of injecting ferric chloride to form an amorphous ferric: oxyhydroxide chemical barrier, We introduced a ferric chloride solution (1,345 mg/l [0.024 m] Fe) to calcite-bearing alluvial gravel to form a chemical barrier of amorphous ferric oxyhydroxide, followed by solutions contaminated with U and Mo. The simulated chemical barriers decreased U and Mo concentrations to less than 0.05 mg/l(2.1 X 10(-7) m) and 0.01 (1.0 X 10(-7) m), respectively; however, the breakthrough front is spread out with concentrations increasing to more than regulatory guideline values sooner than predicted. The hydraulic conductivity of calcite-bearing alluvial gravel decreased substantially during ferric chloride introduction because of the formation of carbon dioxide but increased to within factors of 1 to 5 of the original value as synthetic ground water flowed through the system, Amorphous ferric oxyhydroxide that formed in these experiments remained immobile at flow rates exceeding those typical of ground water, These laboratory results, in conjunction with site-specific characterization data, can be used to design chemical barriers emplaced by injection of ferric chloride.

These alternative reference methodologies have recently been approved by the U.S. EPA for use in lieu of the current standard techniques. The standard EPA methods are prescriptive in selection of sampling locations and in design of sampling probes whereas the alternative reference methodologies are performance driven. Tests were conducted in a stack at Los Alamos National Laboratory to demonstrate the efficacy of some aspects of the alternative reference methodologies. Coefficients of variation of velocity, tracer gas, and aerosol particle profiles were determined at three sampling locations. Results showed that numerical criteria placed upon the coefficients of variation by the alternative reference methodologies were met at sampling stations located 9 and 14 stack diameters from the flow entrance, but not at a location that was 1.5 diameters downstream from the inlet. Experiments were conducted to characterize the transmission of 10 mu m aerodynamic diameter liquid aerosol particles through three types of sampling probes. The transmission ratio (ratio of aerosol concentration at the probe exit plane to the concentration in the free stream) was 107% for a 113 L min(-1) (4-cfm) anisokinetic shrouded probe, but only 20% for an isokinetic probe that follows the existing EPA standard requirements. A specially designed isokinetic probe showed a transmission ratio of 63%. The shrouded probe performance would conform to the alternative reference methodologies criteria; however, the isokinetic probes would not.

The reactions of the primary alkyl halides produced the corresponding phosphonium cationic compotcnds, whereas the secondary and tertiary halides underwent elimination to form the corresponding olefins and the protonated form of 1. Based on H-1 and C-13 NMR studies, it appears that elimination is exclusively trans, favoring the Saytzeff product. It was also observed that this reaction is enhanced by the solvent CH,CN. The X-ray crystal structure of [Me(1)] I is also reported featuring a transannular distance of 2.773 i Angstrom (2) facilitated by a rather wide average equatorial MeN-P-NMe bond angle of 113.1 (2)degrees.

Alkyl(alkenyl) hydroperoxides are formed as intermediates, in the case of isobutane as the final product. This was observed when monitoring the reactions in situ by Fourier-transform infrared spectroscopy. Experiments were typically run at room temperature, in some cases at zeolite temperatures as low as -100 degrees C to elucidate mechanisms. Chemistry was induced by light from a tungsten lamp. Frequently, studies were also conducted with the emission of an Ar ion or cw dye laser in order to determine the visible wavelengths responsible for the reaction. Diffuse reflectance spectra revealed a visible absorption tail which originates from a hydrocarbon . O-2 collision complex. It is attributed to the hydrocarbon . O-2 charge-transfer absorption whose onset is shifted from the UV into the visible region by the very high electrostatic field of the zeolite (shifts of the order of 1.5 to 3 eV). Quantum efficiencies are in the region 10-30%, and selectivities remain high even upon conversion of more than 50% of the hydrocarbon loaded into the zeolite matrix. Many of the reactions studied are of commercial importance: toluene to benzaldehyde, propylene to acrolein or propylene oxide, isobutane to t-butyl hydroperoxide, cyclohexane to cyclohexanone, ethane to acetaldehyde.

During the first few minutes of a cold start of the engine, the emission levels of unburned hydrocarbon and CO pollutants are very high due to the inefficiency of the cold engine and the poor activity of the catalyst at lower temperatures. Therefore, it is necessary to provide an alternative approach to deal with this specific problem in order to meet near-term regulatory requirements. Our approach has been to use known photocatalytic reactions obtainable on semiconducting powders such as titanium dioxide. In this paper, we describe our recent studies aimed at the photocatalytic oxidation of unburned hydrocarbons in automobile exhaust emissions. Our results demonstrate the effective destruction of propylene into water and carbon dioxide. The conversion was found to be a strong function of the propylene flow rate. The reaction rate was studied as a function of time, humidity and temperature. The effect of the power of the UV source on conversion is also discussed. C1 PACIFIC NW LAB, RICHLAND, WA 99352 USA.

The beam is produced by using third-generation insertion devices in a 7-GeV (7 billion electron volts) electron/positron storage ring that is 1,104 meters (2/3 mile) in circumference. The heat load from these intense high-power devices is very high, and certain components must sustain total heat loads of 3 to 15 kW and heat fluxes of 30 W/mm(2). Because the beams will cycle on and off many times, thermal shock and fatigue will be a problem. High heat flux impinging on a small area causes a large thermal gradient that results in high stress. GlidCop(R), a dispersion-strengthened copper, is the desired design material because of its high thermal conductivity and superior mechanical properties as compared to copper and its alloys.

There have been intensive research efforts to develop beam line optics to exploit brightness and coherence properties from undulators. These components must withstand high heat loads produced by intense synchrotron radiation beams impinging on their surface which could degrade beam line performance. The effects of high flux undulator radiation on beam line optics for EUV interferometry and photoemission microscopy will be discussed.

The crystal utilizes a thin, partially transmitting diffracting element fabricated within a liquid-nitrogen cooled, monolithic block of silicon. This report summarizes the results from performance tests conducted at the European Synchrotron Radiation Facility (ESRF) using a focused wiggler beam and at the Advanced Photon Source (APS) on an undulator beamline. These experiments indicate that a cryogenic crystal can handle the very high power and power density x-ray beams of modem synchrotrons with sub-arcsec thermal broadening of the rocking curve. The peak power density absorbed on the surface of the crystal at the ESRF exceeded 90 W/mm(2) with an absorbed power of 166 W, this takes into account the spreading of the beam due to the Bragg angle of 11.4 degrees. At the APS, the peak heat flux incident on the crystal was 1.5 W/mA/mm(2) with a power of 6.1 W/mA for a 2.0 H x 2.5 V mm(2) beam at an undulator gap of 11.1 mm and stored current up to 96 mA.

For example with microfocusing optics, or for coherence experiments, x-ray beams with cross sections less than 0.1 mm(2) are desirable. With such small beams, the total thermal load is small even through the heat flux density is high. Analyses indicate that under these conditions, rather simple crystal cooling techniques can be used. We illustrate the advantages of a small beam monochromator, with a simple x-ray monochromator optimized for x-ray microdiffraction. This monochromator is designed to achieve negligible distortion when subjected to a narrow (0.1 mm wide) beam from an APS undulator A operating at 100 mA. It also allows for rapid and repeatable energy scans and rapid cycling between monochromatic and white beam conditions.

A single reference correction now completely removes both error signals from the measured surface profile. The addition of a precision air conditioner keeps the temperature in the metrology enclosure constant to within +/-0.1 degrees C over a 24 hour period and has significantly improved the stability and repeatability of the system. We illustrate the performance improvements with several sets of measurements. The improved environmental control has reduced thermal drift error to about 0.75 microradian RMS over a 7.5 hour time period. Measurements made in the forward scan direction and the reverse scan direction differ by only about 0.5 microradian RMS over a 500mm trace length. We are now able to put 1-sigma error bar of 0.3 microradian on an average of 10 slope profile measurements over a 500mm long trace length, and we are now able to put a 0.2 microradian error bar on an average of 10 measurements over a 200mm trace length.

The monochromator has a cross section in the shape of the letter U. This monochromator should be suitable for handing heat fluxes up to 5 W/mm(2). As such,for the present application, it is compatible with the best internally cooled silicon crystal monochromators operating at room temperature. There are three key features in the design of this monochromator. First, it is contact cooled, thereby eliminating fabrication of cooling channels, bonding, and undesirable strains in the monochromator due to coolant-manifold-to-crystal-interface. Second, by illuminating the entire length of the crystal and extracting the central part of the reflected beam, sharp slope changes in the beam profile and thus slope errors are avoided. Last, by selecting appropriate crystal geometry and cooling locations, tangential slope error can be substantially reduced.

The total power of the beam is now up to 7.5 kW with closed gap and 60 mA stored particle beam. After a planned upgrade of the undulator, the power can increase to about 15 kW. The vertical white beam slit for the PETRA. undulator beamline is located at about 105 m from the source. The worst case for the slit is when all the power is absorbed in one part of the slit system, which the slits must survive. This paper presents the results from parameter optimization in the worst case. The goal of the optimization is to minimize the maximum temperature of the slits. The geometrical parameters are the cooling hole size, its location from the surface, and the distance between holes. The worst case is found by moving the x-ray beam to all the possible locations. The maximum temperature of an optimized slit that has a two degree angle with the beam is about 192 degrees Celsius. The corresponding thermal stress in the slit is very low. The analysis assumptions, modeling, results, discussion, and conclusion will be given in the paper.

The monochomator is internally cooled through 17 rectangular channels with liquid gallium and is designed to operate at photon energies near 14 keV, under beam from a 2.7 cm period undulator. The atomic planes of the monochromator have a (111) orientation with an asymmetric cut angle of 4.5 degrees. The displacement profile calculated from the structural FEA was used to compute the double-crystal rocking curves at 14.41 keV. Both the simulations and the experiment show that this monochromator will operate at about 40 mA with rocking-curve broadening of only about 0.5 arsec. This corresponds to a surface heat flux of 1.2 W/mm(2) (i.e., 20 W/mm(2) at normal incidence) and a total absorbed power of about 86 watts. The monochromator was used for the commissioning of the beamline and to perform the first series of experiments up to 100 mA. In this paper, we give the results of the FEA calculations and diffraction simulations and compare these to the experimental data.

It is deployed in conjuction with the current commissioning window assembly on the APS insertion device (ID) front ends. The beamline filter at the Advanced Photon Source (APS) will eventually be used in windowless operations also. Hence survival and reasonable life expectancy of the filters under intense insertion device (ID) heat flux are crucial to the beamline operations. To accommodate various user requirements, the filter is configured to be a multi-choice type and ''smart'' to allow only those filter combinations that will be safe to operate with a given ring current and beamline insertion device gap. However, this paper addresses only the thermo-mechanical analysis of individual filter integrity and safety in al combinations possible. The current filter design is configured to have four filter frames in a cascade with each frame holding five filters. This allows a potential 625 total filter combinations. Thermal analysis for all of these combinations becomes a mammoth task considering the desired choices for filter materials (pyrolitic graphite and metallic filters), filter thicknesses, undulator gaps, and the beam currents. The paper addresses how this difficult task has been reduced to a reasonable effort and computational level. Results from thermo-mechanical analyses of the filter combinations are presented both in tabular and graphical format.

At the APS, the insertion devices that generate the x-ray are very powerful. For example, the heat flux associated with an x-ray beam generated by Undulator A will be on the order of 207 W/mm(2) at the L5-80 slit location (about 27.5 m away from the insertion device) at normal incidence. The total power is about 5.3 kW. The optical slits with micron-level precision are very challenging to design under such heat flux and total power considerations. A novel three-metal composite slit has been designed to meet the diverse thermal, structural, and precision requirements. A closed form solution, and a commercial code, ANSYS, have been used for the analysis of the optimized design for the slit set.

In addition to domestic tokamaks such as Tokamak Fusion Test Reactor (TFTR) at Princeton, the DIII-D tokamak at General Atomics, and Alcator C-Mod at MIT, components for international experiments like TEXTOR, Tore-Supra, and JET also have been tested at the PMTF. High heat flux testing spans a wide spectrum including thermal shock tests on passively cooled materials, thermal response and thermal fatigue tests on actively cooled components, critical heat nux burnout tests, braze reliability tests, and safety related tests. The program's main focus now is on testing of beryllium and tungsten armor tiles bonded to divertor, limiter, and first wall components for the International Thermonuclear Experimental Reactor (ITER).

In the current legal, regulatory, and political environments, the timely opening of the WIPP is a virtual reality. A focused organization, well-defined mission, early and iterative interactions with the regulators, oversight groups, and stakeholders in the regulatory process, and strong local support are some of the keys to this progress. However, the timely opening of the WIPP in 1998 could be challenged by changes in national policy and pending laws and regulations.

LA English DT Proceedings Paper CT 7th Annual International Conference on High Level Radioactive Waste Management CY APR 29-MAY 03, 1996 CL LAS VEGAS, NV SP Amer Soc Civil Engineers, Amer Nucl Soc AB Probabilistic forecasting techniques have been used in many risk assessment and performance assessment applications on radioactive waste disposal projects such as Yucca Mountain and the Waste Isolation Pilot plant (WIPP). Probabilistic techniques such as Monte Carlo and Latin Hypercube sampling methods(1) are routinely used to treat uncertainties in physical parameters important in simulating radionuclide transport in a coupled gcohydrologic system and assessing the ability of that system to comply with regulatory release limits. However, the use of probabilistic techniques in the treatment of uncertainties in the cost and duration of programmatic alternatives on risk and performance assessment projects is less common. Where significant uncertainties exist and where programmatic decisions must be made despite existing uncertainties, probabilistic techniques may yield important insights into decision options, especially when used in a decision analysis framework and when properly balanced with deterministic analyses(2). For relatively simple evaluations, these types of probabilistic evaluations can be made using personal computer-based software(3).

The Advanced Fork System measures the neutron and gamma-ray yields and the energy spectrum of gamma-rays from spent fuel assemblies. A cadmium-zinc-telluride (CZT) crystal permits the identification of the radioactive isotopes of cesium (134 and 137). The cesium isotope concentrations, with proper calibration, can be used to determine the assembly burnup independent of reactor records, and to provide a measure of minimum cooling time. Tungsten gamma-ray collimators are used to define the spatial resolution of the gamma-ray detectors along the axis of the assembly. The capability to rapidly perform a burnup distribution scan using the collimated ion chamber may be important to the verification of burnup for boiling water reactors (BWR).

LA English DT Proceedings Paper CT 7th Annual International Conference on High Level Radioactive Waste Management CY APR 29-MAY 03, 1996 CL LAS VEGAS, NV SP Amer Soc Civil Engineers, Amer Nucl Soc AB A new technology,(1) the Depleted Uranium Silicate COntainer Backfill System (DUSCOBS), is proposed to improve the performance and reduce the uncertainties of geological disposal of spent nuclear fuel (SNF). DUSCOBS is designed to: (1) reduce radionuclide release rates from the waste package and (2) reduce the potential for repository nuclear criticality events. As a secondary benefit, it disposes of excess depleted uranium (DU). DUSCOBS also provides benefits for SNF storage and transport. These are discussed in a companion paper.(2) RP Forsberg, CW (reprint author), OAK RIDGE NATL LAB,POB 2008,105 MITCHELL RD,OAK RIDGE,TN 37831, USA.

Correspondingly, numerous compounds of these two actinides have been studied under pressure by synchrotron x-ray diffraction. The maximum pressures reached were on the order of 60-80 GPa, and 300 GPa in one case. The situation is much more difficult for all other actinides. Their high level of radioactivity has up to now prevented their study at synchrotrons, except in a few special cases. In contrast, all actinide metals available in sufficient quantities, and a large number of compounds of highly radioactive actinides, have been studied in high pressure laboratory facilities.

The spallation resistance of the scale that formed depends not only on the intrinsic strength of the oxide and the oxide/metal interface, but also on the development of flaws, such as cracks or pores. Their development is in turn related to the magnitude of the oxide growth stress and the way the scale and the alloy relaxes this stress. Although this complex process is not well understood, this paper presents results obtained from studying the oxidation of Ni and of Al2O3-forming Fe-based alloys to discuss some of the issues. It is pointed out that for NiO on Ni, the dominating factor controlling scale adherence is the development of pores near the scale/metal interface. The degree of pore formation depended strongly on metal purity, with the higher pore density on the lower purity substrate.

At 77 K and in self-field, a maximum J(c) of 2 x 10(5) A/cm(2) was measured after three uniaxial pressing and heat treatment cycles, We also analyzed the transport properties of Ag-clad Bi-2223 tapes as a function of cooling rate. Maximum critical current values were two or three times higher for slow-cooled tapes than for fast-cooled tapes. C1 Argonne Natl Lab, Argonne, IL 60439 USA.

The resulting tapes were subjected to thermomechanical processing and then characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive x-ray analysis (EDX). Layered phase texture was accessed using image analysis software on scanned SEM micrographs. Transport currents were measured at 77 K and zero field by the four-probe method. It was found that tapes with low lead content (x=0.2 and 0.25) showed incomplete conversion to Bi-2223, had small grain size and poor c-axis texture. Tapes having higher lead content (x=0.4 and 0.5) also showed incomplete conversion and the presence of lead-rich secondary phases. Tapes with lead content x=0.3 and 0.35 showed complete conversion to Bi-2223, and had the least amount of secondary phases, the best c-axis texture, and the highest transport currents (J(c)). The carbon content of the precursor powder also had a strong influence on secondary-phase chemistry. C1 Argonne Natl Lab, Argonne, IL 60439 USA.

A series of pseudo-ternary phase diagrams at each PO2 was constructed to describe the evolution of the phase assemblage with temperature. Ag showed limited solubility (2-3 wt.%) in the ceramic melt which depressed the fraction temperature of each step along the decomposition pathway. The first solid phases to form upon the peritectic decomposition of Bi2212 were Bi9Sr11Ca5Ox (<9(11)under bar 5>) and (Sr1-xCax)(14)Cu24O41 (14,24) in 1 bar O-2, (<9(11)under bar 5>) and (Sr1-xCax)CuO2 (11) in .21 bar O-2, and (11), (Sr1-xCax)(2)CuO3 (21), and Bi-2(Sr1-xCax)(3)O-x (23x) in .01 bar O-2. The C content of the samples was controlled by high temperature heat treatment and subsequent exposure to H2O saturated air. It was found that an increase in C content from 30 ppm to 7000 ppm depressed the decomposition temperature of Bi2212 by only 3 degrees C independent of Ag content. Furthermore, it was found that the previously observed depression of the decomposition temperature with the addition of Ag was unaffected by changes in the C concentration from 80 to 1500 ppm.

The range of solubility is, for any given LRE system, strongly dependent on the oxygen partial pressure (PO2) and may be temperature dependent. Nd123ss is of particular interest due to the development of a process for making melt textured material with exceptionally high pinning from this material. From the point of view of superconductivity, the upper end of the subsolidus solid solution is not of particular interest for Nd123ss. However the lower end of the solid solution exhibits a significant dependence on both PO2 and temperature. Under the conditions used in melt texturing these changes should lead to the precipitation of second phases which will pin flux. C1 Iowa State Univ Sci & Technol, Ames Lab, Ames, IA 50011 USA.

A critical current (I-c) of 42 A has been recorded in short-lengths of 37-filament conductors. Critical current density (J(c)) up to 12000 A/cm(2) has been observed at 77 K in 125-m-long monocore and 850m-long multifilament conductors. A high-T-c magnet, fabricated from 770 m of monofilament conductor, generated a record high field of approximate to 1 T at 4.2 K in a field of approximate to 20 T. In-situ strain tests showed that multifilament conductors have better strain tolerance than monofilament conductors. The in-situ bending characteristics of the monofilament conductors indicate that their irreversible strain limit increases with decreasing superconductor/Ag ratio. Superconducting joints and multilayer Ag/superconductor composites have been fabricated with a novel chemical etching technique. Typical I-c through such joints was 23 A, or approximate to 70% of that carried by normal monofilament tapes and approximate to 60% of that carried by multifilament tapes. Preliminary results with multilayer tapes show that continuous Ag reinforcement of the BSCCO core improves strain tolerance of the tapes so they can carry 90% of their initial I-c at 1% bend strain in spite of a higher superconductor/Ag ratio than unreinforced tapes.

An as-synthesized oxide mix with this stoichiometry was found to melt at a temperature <700 degrees C. The lead-rich "3221" phase was found to have a wide range of compositional stability in terms of Pb/Bi ratio and Bi + Pb stoichiometry. Evidence was seen for the co-existence of this phase with (Ca,Sr)(2)PbO4 in partially processed Ag/Bi-2223 composites that were cooled slowly through the 800 to 600 degrees C range.

This study investigates improvements in J(c) generated by modifying the strain-state during rolling of silver-sheathed Bi2Sr2Ca2Cu3O10+x (BSCCO-2223) tape using quantitative image analysis of the different phases. Pure compression and combined compression-shear loading was achieved by embedding BSCCO-2223 tapes at different locations within thick steel blocks. High hydrostatic compressive stress was imposed by confining the tape width. Tapes deformed with combined shear-compression exhibited measurably higher J(c) values than tapes subjected to pure compression, but their microstructures showed little difference in the amount of non-conducting (including porosity) phase content. However, constraining the tape width resulted in the most significant increase in J(c) which corresponded to a much lower porosity and non-conducting phase volume in the oxide near the tape edge.

Syringyl compounds are uniformly more susceptible to oxidation than the analogous guaiacyl and p-hydroxyl compounds. The current work reports on the completion of molecular orbital calculations for the lignin model substrates, in an attempt to rationalize the observed differences in reactivity. The energies of the highest occupied molecular orbital (HOMO), charge on the phenolic oxygen, and frontier molecular orbital coefficients on the phenolic hydrogen are consistently greater for the syringyl compounds, In addition, syringyl compounds have lower bond dissociation energies for hydrogen abstraction.

In mammals, apoB can be edited post-transcriptionally to encode a truncated form of apoB (apoB48) that is unable to form either of these atherogenic lipoproteins. To study the effect of increasing hepatic apoB editing activity on formation of Lp(a), a recombinant adenovirus encoding rat apoBEC-1, the cytidine deaminase component of the apoB mRNA editing complex, was administered to human apoB/apo(a) transgenic mice. This resulted in expression of apoBEC-1 in hepatocytes of these mice, increased hepatic editing of bur man apoB mRNA, and decreased plasma levels of human apoB100 and Lp(a). The apoBEC-1 recombinant adenovirus was also administered to rabbits, an animal which, like humans, naturally lacks hepatic apoB editing. Expression of the exogenous apoBEC-1 in rabbit liver resulted in editing of up to 10% of apoB mRNA. Hepatic apoB editing was associated with lower LDL levels in these rabbits relative to those treated with a control adenovirus. However, LDL levels were elevated significantly in both animals as a result of adenovirus injection. These studies demonstrate that introduction of the cytidine deaminase apoBEC-1 is sufficient to induce hepatic apoB editing in an animal lacking this activity, and that induction of editing could serve as a novel approach for lowering plasma concentrations of the atherogenic lipoproteins Lp(a) and LDL.

Ultrafilters are particularly useful in the approximate sizing of colloidal humic and fulvic acids with effective diameters below 0.45 mu m. By first using hollow-fiber filters and then stirred-cell flat ultrafiltration techniques, these naturally occurring organics can be separated into size fractions down to approximately 500 molecular weight. Sufficient material can be obtained by using these size-sampling methods to apply a number of chemical and physical characterization techniques. Examples are presented of size-specific data obtained for fulvic and humic acids with a variety of spectroscopic techniques (e.g., infrared, ultraviolet-visible, C-13 nuclear magnetic resonance, and mass spectroscopy) and pyrolysis gas chromatography. Inorganic trace element analysis and radiochemical characterization of the materials bound to the humic and fulvic size fractions can yield information on the geochemical importance of these natural organics in the migration of low-level wastes.

The dissolved organic carbon and major cation contents were compared with the CIR spectra to estimate the active carboxylate units in each size fraction. Comparison of infrared spectra at various pH values for aquatic humics and for model polycarboxylate compounds (polymaleic acid and polyacrylic acid) indicated that the principal metal binding functionalities are carboxylate groups.

The kinetics with the PAA samples were significantly faster, presumably reflecting the homogeneity and monofunctional nature of PAA relative to HA. The HA kinetics involved pathways on a fast time scale similar to those for PAA as well as much slower pathways. For both PAA and HA, the kinetics were faster with the lower molecular weight fractions, reflecting the role of decreased conformational change as the size decreases.

These complexants decompose slowly, releasing phosphate to promote the formation of stable phosphate mineral phases, particularly with the more soluble trivalent, pentavalent, and hexavalent actinide ions. The complexant of choice, myo-inositol(hexakisphosphoric acid) or phytic acid, is a natural product widely used as a nutritional supplement. We have determined that phytic acid decomposes slowly in the absence of microbiological effects, that crystalline phosphate minerals are formed as a consequence of its decomposition, and that the formation of actinide (lanthanide) phosphates reduces the solubility of trivalent and hexavalent metal ions under environmental conditions.

Highly detailed analyses have been conducted on processes to produce hydrogen from biomass; these processes are indirectly heated gasification followed by steam reforming of the syngas, and pyrolysis followed by steam reforming of the pyrolysis oil. Because biomass pyrolysis oil is similar to crude oil in that many chemicals and fuels can be derived from it, the impact of coproduct options on the economics of producing hydrogen from pyrolysis-based technologies was also studied. Economic assessments of solar and biologically-based hydrogen production processes have focused on the steps that need to be taken to improve the competitive position of these technologies. Within the United States Hydrogen Program, a number of techniques are used to evaluate and compare hydrogen technologies. Different levels of analysis are used for fundamental, advanced, and near-commercial processes. The appropriate level depends on the availability of data and system design. The level of analysis appropriate for a project is dictated by the maturity of the technology and the amount of data that has been gathered, as well as the purpose of the evaluation. A new initiative may require only a literature search in order to determine if process costs can be estimated from related systems or if laboratory data is needed first. Alternatively, a cost boundary analysis is appropriate for a project which has been conceptualized but has not generated a significant amount of data. This type of analysis determines the minimum yields, maximum manufacturing costs, and necessary market conditions for the technology to be economically competitive. Finally, a highly detailed analysis can be performed on processes which have been more or less fully conceptualized, and for which laboratory work has provided yield and operating data. The purpose of performing technoeconomic, or systems analyses is several-fold. First, in a research environment, the near and eventual economic competitiveness of a project can be assessed. Second, results of any of these levels of analysis are useful in guiding experimental planning. Additionally, on-going analysis can be used to track the progress of research Results of the initial economic assessments of other renewables-based hydrogen production processes have been used to direct research efforts toward the most efficient means of reducing costs.

These vehicles can also be manufactured with increased but not excessive cost. Hydrogen-fueled engines have demonstrated indicated efficiencies of more than 50% under Iran operation. Combining optimized engines and other advanced components, the overall vehicle efficiency should approach 40%, compared with 13% for a conventional vehicle in the urban driving cycle. The optimized engine-generator unit is the mechanical equivalent of the fuel cell but at a cost competitive with today's engines. The increased efficiency of hybrid-electric vehicles now makes hydrogen fuel competitive with today's conventional vehicles. Conservative analysis of the infrastructure options to support a transition to a hydrogen-fueled light-duty fleet indicates that hydrogen may be utilized at a total cost comparable to the 3.1 cents/km U.S. vehicle operators pay today while using conventional automobiles. Both on-site production by electrolysis or reforming of natural gas and liquid hydrogen distribution offer the possibility of a smooth transition by taking advantage of existing large-scale energy infrastructures. Eventually, renewable sources of electricity and scalable methods of making hydrogen will have lower costs than today.

The hydrogen can be used to reduce CO2 from coal-fired power plants to produce methanol which can be used as an efficient automotive fuel. The kinetics of methane decomposition is studied in a one inch diameter tubular reactor at temperatures between 700 degrees C and 900 degrees C and at pressures between 28 at 56 atm. The Arrhenius activation energy is found to be 31.3 kcal/mol of CH4. The rate increases with higher pressures and appears to be catalyzed by the presence of carbon particles formed. The conversion increases with temperature and is equilibrium limited. A thermodynamic study indicates that hydrogen produced by methane decomposition while sequestering the carbon produced requires the least amount of process energy with zero CO2 emission. Application to methanol synthesis by reacting the hydrogen with CO2 recovered from coal burning power plant stack gases can significantly reduce CO2 from both the utility and transportation sectors.

Our efforts have focused in understanding the catalysis of oxygenate steam reforming that leads to a successful process at reasonable steam-to-carbon ratios and process severity. We carried out rapid screening of feedstocks and catalysts using a microreactor interfaced with a molecular beam mass spectrometer (MBMS). Time-on-stream studies are now underway using a bench-scale reactor to ascertain the durability of the catalysts and thus substantiate the scientific and technical feasibility of the catalytic reforming option.

The first employed a hydrogenase activity found in unique strains of photosynthetic bacteria that functions in darkness to shift CO (and H2O) into H-2 (and CO2). Mass transport of gaseous CO from thermally gasified biomass into an aqueous bacterial suspension is the rate-limiting step and the main challenge for bioreactor design. A simple method using hollow-fiber technology to enhance mass transfer of CO has proven effective. Hydrogen production from CO at an average rate of 125 ml . g cdw(-1). h(-1) (maximum rate of 700 ml . g cdw(-1). h(-1)) was observed for more than 6 months. In the second bioreactor, photoproduction of H-2 from H2O at an average rate of 9.1 ml . g cdw(-1). h(-1) was observed in a hollow-fiber photobioreactor incorporating an immobilized Anabaena variabilis mutant that lacked uptake hydrogenase activity. The unique aspect in this case was the use of light energy to produce H-2 from water mediated by the cyanobacterium's nitrogenase enzyme complex. The activity lasted for a period of 6 months under ambient conditions in the presence of O-2. RP Markov, SA (reprint author), NATL RENEWABLE ENERGY LAB,1617 COLE BLVD,GOLDEN,CO 80401, USA.

Light, incident on a semiconductor electrode, splits water directly. A one-step monolithic system such as this eliminates the need to generate electricity externally and subsequently feed it to an electrolyzer. We report here on our work involving the application of tandem cell technology to photoelectrochemical water splitting. Tandem cell technology connects photovoltaic layers (p-n junctions) with different semiconductor bandgaps in series, one behind the other in a single monolithic device. This configuration provides a greater utilization of the solar spectra giving rise to higher theoretical efficiency, and the monolithic structure minimizes the amount of active area needed. Tandem cells consisting of GalnP(2)/GaAs homojunctions, were studied for the to photoelectrochemical decomposition of water into hydrogen and oxygen from an aqueous electrolyte solution. To catalyze the water decomposition process, the illuminated surface of the device was modified either by addition of platinum colloids or by coating with ruthenium dioxide. These tandem cells also showed an apparent unusual and unexpected property of both the hydrogen and oxygen evolution reactions occurring simultaneously at the illuminated surface. This has been attributed to an oscillatory chemical reaction initiated by the lack of current matching between the top and bottom cells and the addition ct a Schottky type junction at the semiconductor electrolyte interphase.

Up to 65% of the captured antiprotons have subsequently been cooled by electron cooling to energies below 1 eV and have been stored up to one hour. This has opened new discussions of the possible use of ultralow-energy antiprotons for nuclear, atomic, and gravitational physics. For most of these experiments it will be necessary to extract the antiprotons from the trap in the form of either a continuous beam or as a bunched beam, allowing the timing structure to be used for post-acceleration schemes or as a time tag for subsequent measurements. We have designed an extraction scheme to accomplish this and have tested portions of it using a smaller-scale Penning trap loaded with protons.

Muonic tritium atoms were created following transfer of negative muons from muonic protium in a layer of solid hydrogen (protium) containing a small fraction of tritium. The atoms escaped from the solid layer via the Ramsauer-Townsend mechanism, traversed a drift region of 18 mm, and then struck an adjacent layer of deuterium, where the muonic atom could form a molecular system. The time of detection of a fusion product (neutron or alpha) following muon arrival is dependent upon the energy of the muonic tritium atom as it traverses the drift region. By comparison of the time distribution of fusion events with a prediction based on the theoretical energy dependence of the rate, the strength of resonant formation can in principle be determined. The results extracted so far are discussed and the limitations of the method are examined. C1 INST NUCL PHYS, PL-31342 KRAKOW, POLAND. UNIV VICTORIA, VICTORIA, BC V8W 2Y2, CANADA.

The measurements were performed on the muon beam of PSI with a multi-anode high-pressure ionization chamber filled with isotopically pure He-3 or He-4 at 120 bar. The chamber was used as a target and detector for both the incoming muons and for the charged reaction products (tritons, deuterons and protons) of the breakup reactions mu(-) + He-3 --> d + n + v(mu), p + 2n + v(mu) and mu(-) + He-4 --> t + n + v(mu), d + 2n + v(mu), p + 3n + v(mu). Our statistics, about 5 x 10(5) of breakup events, provides a possibility to improve the precision of evaluated rates. The preliminary results: Lambda(B)(He-3) = 720 +/- 70 s(-1), Lambda B(He-4) = 415 +/- 40 s(-1) are compared to theoretical predictions and to previous experiments.

In antiproton-catalyzed fusion, the negative antiproton shields the repulsion between the positively charged nuclei of hydrogen isotopes, allowing a much higher level of penetration through the repulsive Coulomb barrier and greatly enhancing the fusion cross section. With their more compact wave function, the more massive antiprotons offer much more shielding than negative muons. If the antiproton could exist in the ground state with a nucleus for a sufficient time without annihilating, the fusion cross sections are so enhanced at low energies that at room temperature, values up to about 1000 barns (d + t) would be possible. Unfortunately, the cross section for antiproton annihilation with the incoming nucleus is even higher. A model giving an upper bound for the fusion to annihilation cross section ratio for all relevant energies indicates that each antiproton will catalyze no more than about one fusion. Since the energy to make one antiproton greatly exceeds the fusion energy released, this level of catalysis is far from adequate for power production.

Our first objective will be a precise measurement of the absolute rates of resonant and nonresonant dd mu formation in D-2 and HD-gases and their temperature dependence from 40 to 350 K. Both output channels of the dd-reaction: He-3 + n and t + p will be observed and their ratio sensitive to contributions of S and P-waves will be determined. Simultaneously, we shall investigate the pd mu-cycle and determine the absolute pd-fusion yields in different molecular H/D compositions, observing tritons from nuclear muon capture in He-3 mu: pd mu + He-3 mu + gamma.

We have characterized the thickness and uniformity of frozen targets using the energy loss of alpha particles. An accuracy of similar to 5% was achieved, a limit imposed by the uncertainty in the stopping powers. The details of the method are described, and the thickness calibration of the target is presented. C1 UNIV VICTORIA, VICTORIA, BC V8W 2Y2, CANADA. TRIUMF, VANCOUVER, BC V6T 2A3, CANADA.

These antiprotons have subsequently been cooled by electron cooling. This has opened new discussions of the possible use of ultra-low energy antiprotons for nuclear, atomic, and gravitational physics. For most of these experiments, it will be necessary to extract the antiprotons from the trap in a continuous or bunched beam, allowing the timing structure to be used for post-acceleration schemes or as a time tag for the subsequent measurements. We have designed an extraction scheme to accomplish this and have tested portions of it using a smaller Penning trap loaded with protons. First results in generating a time-correlated beam of particles from a Penning trap are presented. C1 LOS ALAMOS NATL LAB,LOS ALAMOS,NM 87545. PENN STATE UNIV,COLLEGE PK,PA.

The g measurement method is based on the study of the gravity-induced shift of the center of the radial orbits of particles stored in a Penning trap having the magnetic field perpendicular to the direction of the force of gravity. The analysis of the radial motion shows that forces originating from patch effect electrical fields about ten times stronger than the force of gravity, still allow a differential measurement of g for antiprotons and matter particles (H-). As the precision of the measurement is affected by the particle axial energy distribution, particular care must be devoted to injecting antiprotons and H- ions into the trap with very similar initial conditions.

Examples of line position measurements include studies of the K-shell transitions in heliumlike Kr34+ and the 2s-2p intrashell transitions in lithiumlike Th87+ and U89+, which provide benchmark values for testing the theory of relativistic and quantum electrodynamical contributions in high-Z ions. Examples of line intensity measurements are provided by measurements of the electron-impact excitation and dielectronic recombination cross sections of the heliumlike transition-metal ions Ti20+ through Co25+. A discussion of radiative lifetime measurements of metastable levels in heliumlike ions is given to illustrate our time-resolved spectroscopy techniques in the microsecond range.

The utility of this promising technology is reviewed and the essential requirements for efficient ablation extracted. Recent data obtained on the ablation of painted steel surfaces and concrete are presented. The effects of beam irradiance, ablation speed and efficiency, and characteristics of the aerosol effluent are discussed. Characterization of the ablated components of the surface offers the ability of concurrent determination of the level of contamination. This concept can be applied online where the ablation endpoint can be determined. A conceptual system for the characterization and decontamination of surfaces is proposed.

The laser cutting demonstration will be conducted in two phases, The first phase will be a non-radioactive test to ensure the abilitpr ofhot cell remote manipulators to use the laser end effector to successfully cut the types of materials and geometries found in the hot cell, The second phase will introduce the laser end effector and the associated fiber optic cable into the hot cell radiation environment, The testing in the hot cell will investigate the degradation of the optical portions of the end effector and transmission cable in the high radiation field. The objective of the demonstration is to assess the cutting efficiency and life limitations of a laser cutting system for radioactive D&D, operations. A successful demonstration will, therefore, allow the laser cutting technology to be integrated into the baseline planning for the D&D of DOE facilities throughout the nation.

The resistivity, about 10,000 Ohm-cm, allows for operation of the CCD with the entire 300 mu m substrate depleted. This results in better red to near infrared response when compared to conventional and thinned CCDs. In addition the CCD has good blue response when back illuminated. Since the substrate is fully depleted, thinning, with its inherent difficulties, is not necessary in order to enhance blue response.

In this study, we present a scheme which controls traffic by dynamically allocating/de-allocating resources among competing VCs based upon their real-time requirements. This scheme incorporates a form of rate-control, real-time burst-level scheduling and kink-link flow control. We show analytically potential performance improvements of our rate-control scheme and present a scheme for buffer dimensioning. We also present simulation results of our schemes and discuss the tradeoffs inherent in, maintaining high network utilization and statistically guaranteeing many users' Quality of Service.

A stochastic knowledge representation paradigm is proposed, and a way to encode this knowledge form into cycles in fully-connected networks is described. This new representation format stores information in a truly distributed manner across the network, as opposed to previous schemes which store one knowledge atom per neuron.

The algorithm segments an image by first constructing a minimum spanning tree representation of the image and then partitioning the spanning tree into subtrees representing different homogeneous regions. The spanning tree is partitioned in such a way that the sum of gray-level variations over all partitioned subtrees is minimized under the constraints that each subtree has at least a specified number of pixels and two adjacent subtrees have significantly different ''average'' gray-levels. Two types of noise, transmission errors and Gaussian additive noise, are considered and their effects on the segmentation algorithm are studied. Evaluation results have shown that the segmentation algorithm as robust in the presence of these two types of noise.

Finally, it is shown that the associated residual or so-called innovation sequence that ensues from the recursive nature of this formulation can be employed to monitor the model's fit to the data.

The proposed differentiator approach yields comparable residual energy compared with that obtained employing the linear predictor technique, The two main advantages of the differentiation method are: 1) the coefficients are fixed integers which do not have to be encoded; and 2) greatly reduced computational complexity, relative to the existing algorithms, These advantages are particularly attractive for real time processing, They have been confirmed experimentally by compressing different seismic signals, Sample results including the compression ratio, i.e., the ratio of the number of bits per sample without compression to those with compression using arithmetically encoded residues are also given.

A single expression is derived for the probability of search success which covers all overlap cases. Making the further assumption that search strategy is chosen so as to maximize expected value, yields the result that each point on the search field must be fixated an integral number of times. In an experiment where visual lobe size and fixation duration were controlled, human subjects behaved in a manner close to that predicted by the optimization model. It is concluded that further development of the model using less restrictive assumptions is warranted. C1 SUNY BUFFALO,DEPT IND ENGN,BUFFALO,NY 14260. ARGONNE NATL LAB,ARGONNE,IL 60439.

However, the deep ionization energy level of Mg in GaN (similar to 160 meV) limits the ionized of accepters at room temperature to less than 1.0% of the substitutional Mg. With this in mind, we used ion implantation to characterize the ionization level of Ca in GaN since Ca had been suggested by Strite [1] to be a shallow acceptor in GaN. Ca-implanted GaN converted from n-to-p type after a 1100 degrees C activation anneal. Variable temperature Hall measurements give an ionization level at 169 meV. Although this level is equivalent to that of Mg, Ca-implantation may have advantages (shallower projected range and less straggle for a given energy) than Mg for electronic devices. In particular, we report the first GaN device using ion implantation doping. This is a GaN junction field effect transistor (JFET) which employed Ca-implantation. A 1.7 mu m JFET had a transconductance of 7 mS/mm, a saturation current at 0 V gate bias of 33 mA/mm, a f(t) of 2.7 GHz, and a f(max) of 9.4 GHz. O-implantation was also studied and shown to create a shallow donor level (similar to 25 meV) that is similar to Si. SIMS profiles of as-implanted and annealed samples showed no measurable redistribution of either Ca or O in GaN at 1125 degrees C.

A thin polycrystalline cubic TiN layer epitaxially matched to the (0001) GaN surface was detected at the interface with the GaN substrate. This layer was studied in detail by electron diffraction and high resolution electron microscopy. The orientation relationship between the cubic TiN and the GaN was found to be: {111}(TiN)//{00.1}(GaN), [110](TiN)//[11.0](GaN), [112](TiN)//[10.0](GaN). The formation of this cubic TiN layer results in an excess of N vacancies in the GaN close to the interface which is considered to be the reason for the low resistance of the contact.

Low temperature photoluminescence yields much higher intensity emission in the near bandedge region for epitaxial films with respect to the situation in bulk crystals. Character of this luminescence changes also. Dominant band-to-band transitions in the bulk crystals are exchanged by bound exciton and/or donor-acceptor pair transitions observed in the epitaxial layers. We will compare the obtained results with the available data on the homoepitaxial samples grown by metalorganic chemical vapor deposition method and discuss the importance of establishing the basic information on energetic positions of excitonic transitions in stress free samples.

Undoped and low Si doped samples were compared with samples of increased dopant concentration. In addition, defect reduction due to different buffer layers (AIN and GaN) is discussed. Silicon doping improves surface morphology and influences threading dislocation arrangement. High doping leads to a more random distribution of dislocations. Based on this study it appears (for the same dopant concentration) that an AIN buffer layer can significantly reduce the number of threading dislocations, leaving the samples more strained However, no significant reduction of threading dislocations could be observed in the samples with GaN buffer layer. These samples are the least strained. RP LilientalWeber, Z (reprint author), UNIV CALIF BERKELEY,LAWRENCE BERKELEY LAB,DIV SCI MAT,BERKELEY,CA 94720, USA.

A two-dimensional charge-coupled device (CCD) was used as a detector. The AOTF was used as a wavelength selector. Unlike a tunable grating or prism based monochromator, the tunable filter has no moving parts, and it can be rapidly tuned to any wavelength in its operating range. The large aperture of the AOTF and its high spatial resolution allowed the optical image from an IFP to be recorded by the CCD. These characteristics, combined with their small size, make AOTFs important new alternatives to conventional monochromators, especially for spectral imaging in biomedical applications.

The new genes were mapped back to the YAC by a combination of optical restriction mapping and pulse field gel electrophoresis. Northern analysis of individual clones demonstrated the presence of either different mRNA sizes or different expression patterns. Two of the cDNA clones were expressed only in lymphoid cell lines: one in Jurkat cells (T cell) and another in JY cells (B cell). All the genes lacked sequence similarity to any known classical and non-classical major histocompatibility complex (MHC) class I genes, indicating that the MHC class I region has more functions than anticipated. Of the seven new genes, one is highly similar (97%) to mouse 60S ribosomal protein, and another is homologous to diubiquitin proteins. Of the two G-coupled receptor-like cDNAs, one was fully sequenced and found to be an olfactory receptor-like gene. The study strengthens evidence that the MHC complex not only plays a key role in the immune system, but also contributes to non-immunological functions. C1 NYU,DEPT CHEM,NEW YORK,NY 10003.

Model formulation and verification SO IN SITU LA English DT Article AB This is the first of two papers illustrating the design and results of a steam drive pilot in the South Belridge Diatomite, Kern County, California. Steam drive on 5/8 acre spacing appears to be an economically viable alternative to waterflooding in the Diatomite; hence, it is being explored as a secondary recovery process. To interpret steam drive results quantitatively, we propose a computationally simple, high-resolution model that captures formation heating due to both steam/hot condensate convection and heat conduction, evolution of formation permeability, and changes in the size and shape of injection hydrofractures. From this model, we obtain formation pressure, temperature, the cumulative steam injection, the dynamics of hydrofractures undergoing steam injection, and, thus, a history match for the pilot. Model results can then be used to generate input data for a fully compositional three-dimensional simulator and even more detailed study. The two, separate, noncommunicating hydrofractures used for steam injection collectively span the entire diatomite reservoir column. Concentrating first on steam injection through the lower hydrofracture, we interpret results obtained between October 1989 and January 1994. It is discovered that steam did not flow into the outer portions of the hydrofracture wings for roughly 225 days of injection and that formation heating was asymmetrical. Over time, the hydrofracture grew, thereby improving volumetric heating. The most dramatic evolution of hydrofracture shape occurred across the bottom 150 ft of the lower fractured interval. The hydrofracture wings increased their length many fold in response to steaming. Further, the most permeable layers of diatomite demonstrated the greatest heating because steam preferentially entered and convected within these layers.

Asymmetric hydrofractures SO IN SITU LA English DT Article AB This is the second part of a two-paper series illustrating the results of a steam drive pilot in the South Belridge Diatomite, Kern County, California. In this pilot, steam is injected through two noncommunicating, vertical hydrofractures that nearly span the entire 1000-ft-tall diatomite column. The first paper examined steam convection and heating resulting from injection into the lower hydrofracture. Here, we apply a high-resolution numerical model developed in the first paper and interpret the results of steam injection through the upper hydrofracture in the pilot between October 1989 and January 1994. Results of this analysis indicate that the upper injection hydrofracture was highly dynamic and asymmetrical while undergoing steam injection. Steam flowed preferentially into the northern wing of the hydrofracture, which reached a final wing length of 250 ft. To the south, hydrofracture wing length reached roughly 75 ft and diatomite heating was weak. A dramatic temperature response above the perforated interval of the upper injection well suggests that a horizontal fracture, or network of natural fractures, opened within the formation and linked to the injection hydrofracture. Our analysis indicates that roughly 43 percent of the total injected steam migrated above the perforations of the injection well, but remained within the Diatomite, and flowed rapidly away from the fracture face because of a large increase of hydraulic diffusivity of the formation.

The present study was undertaken to investigate this possibility. Fischer 344 rats were exposed to 23.2 ppm phosgene or air for 70 min, and bronchoalveolar lavage was performed during the early development of the pulmonary edematous response to phosgene, that is, 1 and 3 h after exposure. Lavage fluids were analyzed for the presence of TNF-alpha, and the constitutive and lipopolysaccharide (LPS)-stimulated productions of TNF-alpha by lavaged alveolar macrophages (AM) were assessed in vitro. No increases in TNF-alpha in the lavage fluids were observed at either of the two time points after phosgene exposure. The numbers and viabilities of AM lavaged 1 h after exposure to phosgene and air were closely similar. By 3 h after exposure to phosgene, fewer AM were harvested by lavage and their viabilities were reduced below air control values. The unstimulated or LPS-stimulated production of TNF-alpha by the AM from the air- and phosgene-exposed lungs was not significantly different from one another when assessed by an enzyme-linked immunosorbent assay for murine TNF-alpha, whereas TNF-alpha production measured by an L929 cell cytotoxicity assay indicated that the production of this proinflammatory cytokine by LPS-stimulated AM was abnormally decreased at both the 1- and 3-h, postexposure times. The results of this study suggest that TNF-alpha production by AM does not play an important role in mediating the early phase of development of phosgene-induced pulmonary edema.

A two-dimensional charge coupled device (CCD) was used as a detector. The AOTF was used as a wavelength selector. Unlike a tunable grating or prism based monochromator, the tunable filter has no moving parts, and it can be rapidly tuned to any wavelength in its operating range. The large aperture of the AOTF and its high spatial resolution allowed the optical image from an IFP to be recorded by a CCD. These characteristics, combined with their small size, make AOTF's important new alternatives to conventional monochromators, especially for spectral multisensing and imaging. A prototype RSIS system, using both IFP and AOTF, was developed and its feasibility for spectral imaging was demonstrated.

We model manufacturing as a network of machines and assign a computer workstation called server to each machine, The information processing requirements of a production order or a lot are encapsulated in an object that migrates between the servers after completion of an appropriate service. An event and rule based implementation and a layered approach allows design of CIM systems that can be easily reconfigured in response to changes in products or processes. Moreover, the architecture is compatible with distributed systems used in product design. The traditional hierarchical and distributed control architectures are shown to be special cases of the proposed architecture. Finally, an implementation using next-generation database management systems is proposed. (C) 1996 John Wiley & Sons, Inc. C1 UNIV CALIF BERKELEY,WALTER A HAAS SCH BUSINESS,BERKELEY,CA 94720.

The EAM is used to consider the effect of hydrogen on the structure and properties of boundaries in nickel and nickel aluminide (Ni3Al). In both cases hydrogen segregates to the boundary causing a reduction in the cohesive strength. Next, the EAM is applied to describe the equilibrium and dynamic structure of a dissociated Sigma 3(112) boundary in copper. Comparison is made to recent experimental observations which show good agreement with the modeled behavior. Finally, the MEAM is used to help understand the properties of both the nickel/silicon and aluminum/sapphire systems. C1 SEAGATE TECHNOL,BLOOMINGTON,MN 55420. SANDIA NATL LABS,LIVERMORE,CA 94551.

The vapor-grown bicrystal films contained mainly 90 degrees [110] tilt boundaries with fixed misorientation but variable inclination, as well as some growth twins with 70.5 degrees [110] symmetrical tilt boundaries and a few small-angle boundaries. It was found that the shape, size and orientation of the inclusions in the grain boundaries depend on the orientation of the aluminum grain boundary plane. Inclusions at 90 degrees [110] tilt boundaries were invariably sharply faceted toward one aluminum grain and more rounded toward the other grain. The faceted side was a section of the cuboctahedral equilibrium shape of bulk lead inclusions in parallel topotaxy with the aluminum matrix. The rounded side, where the aluminum grain was rotated by 90 degrees with respect to the lead lattice, approximated a spherical cap. At specific low-energy segments of the grain boundary where a (100) plane in grain 1 meets an (011) plane in grain 2, only two of several possible shapes were observed. One of these was preferred in as-implanted samples while both types were found after melting and re-solidification of the lead inclusions. The observations are discussed in terms of a modified Wulff construction. C1 NIELS BOHR INST, ORSTED LAB, DK-2100 COPENHAGEN 0, DENMARK.

Type I laths exhibit a rectangular cross section, with interfaces parallel to low-index planes, while Type II laths are parallelogram-shaped, with their major interface at 13 degrees to the type I precipitate. The corresponding orientation relationships differ by a 1.8 degrees rotation around the lath axis. In this study, the difference between the two characteristic morphologies and orientation relationships is shown to be the formation of an invariant line strain for type II precipitates. On an atomic scale, both interfaces have a terrace and ledge structure but differ in the stacking sequence of interfacial ledges associated with partial dislocations. The structural unit model and the invariant line model predict identical interface geometries which agree closely with the observations. C1 CNRS,CTR ETUD CHIM MET,F-94407 VITRY SUR SEINE,FRANCE.

High resolution electron microscopy reveals the presence, along the same interface, of ledges separating facets with different atomic structures. Some facets are associated with certain interfacial thicknesses since their structures involve one planar fault or an intermediate ultrathin Ni3Al crystal. The observed ledges are associated with a misfit dislocation (MD) with b = (-1/6)[112]Ni3Al. This vector is determined from the comparison of the experimental images and simulated images. The multislice method has been applied with atom boxes which account for the elastic field surrounding each misfit dislocation core.

By exploiting microfabrication methods and hot pressing, identical arrays of internal micron-sized pores were produced. These pores undergo shape changes during high temperature annealing that can be followed in transparent ceramics by using optical microscopy. Ti additions substantially accelerated morphological change. After no further shape changes were evident, the internal pores were re-exposed by either fracture or by a serial sectioning procedure. Once re-exposed, atomic force microscopy was used to assess the pore shape. At a minimum, facets, if present, can be indexed. In an ideal case, a complete mapping of che Wulff shape may be possible.

Our results indicate that brittle grain-boundary fracture in Ni3Si is caused by two major factors: (1) moisture-induced hydrogen embrittlement, and (2) poor grain-boundary cohesion. Boron is found to segregate strongly to grain boundaries and suppress environmental embrittlement in Ni3Si. Boron, however, does not enhance the cohesive strength of the boundaries. As a result, Ni3Si showed a moderate increase iri room-temperature tensile ductility in moist air when doped with boron. Auger analyses indicate that the silicon concentration at the grain boundaries is significantly lower than that in the bulk; however, there is no indication of strong co-segregation of nicker and boron atoms to the boundaries.

Positive temperature dependence of yield stress was observed in all the orientations examined. Orientation-dependent phenomena in the temperature range where temperature dependence of yield stress is positive, viz., orientation dependences of yield stress and critical resolved shear stress (CRSS), peak stress and peak temperature, and serrated flow behavior, shows trends opposite to those obtained in compression by our previous work. Based on the present results, it is concluded that those orientation-dependent phenomena represent intrinsic characteristics of deformation behavior associated with the positive temperature dependence of yield stress.

Previous work has shown that the oxidation rate of Mo5Si3 can be decreased with the addition of boron. By adding 1 3 wt % boron to a silicon deficient composition, a three phase microstructure composed of Mo5Si3 (T1), Mo5Si3, and a ternary Mo-5(Si,B)3 (T2) phase was synthesized. The compressive creep rate of this composition was evaluated at 1240-1320 degrees C and 120-180 MPa. The average creep stress exponent and activation energy for the three phase material were found to be n = 4.3 and E(a) = 396 kJ/mol. TEM analysis of the crept microstructure of the boron modified material reveals no evidence for dislocation activity in T1. Only basal slip was observed in the T2 phase while polygonal sub-grain structures were observed in Mo3Si. (C) 1996 Elsevier Science Ltd.

In addition, three quaternary alloys, each containing 1 at% Cr were also similarly tested to verify previously reported beneficial effects of the Cr addition. The embrittlement sensitivity to hydrogen partial pressure was studied. The results of this study showed that the severity of embrittlement is strongly dependent on alloy stoichiometry, that Cr addition does not provide any direct benefit, that embrittlement is a function of the hydrogen partial pressure in the environment, and that molecular hydrogen dissociation is more critical than water vapor dissociation. Based on the data, it is argued that hydrogen 'wetting' of the crack tip and hydrogen penetration play a role in embrittling the alloys, the relative importance being stoichiometry-dependent.

In this paper, we compare and contrast the mechanical properties such as yield strength, ultimate tensile strength, and tensile elongations of Ni3Al-based alloys, Fe3Al-based alloys, and FeAl alloys with several of the commercially available superalloys such as Haynes 214 (NiCrAlY), MA-956 (yttria-dispersed FeCrAlY), and a FeNiCr alloy (HU steel) used in carburizing applications. Our comparisons clearly show that cast and wrought Ni3Al-based alloys exhibit superior mechanical properties over the commercially available alloys such as the FeNiCr HU steel and Haynes 214. Electrical resistivity of iron aluminides increases with the increase of aluminum content, and the electrical resistivities of Fe3Al- and FeAl-based alloys are 50-100% higher than those of commercially available heating-element materials. Processing problems associated with the melting and casting of intermetallics are discussed in light of their large, negative heats of formation; high-aluminum content of intermetallics; and the safe operating temperatures of crucible materials for melting them. A furnace-loading sequence enabled us to properly utilize the heat of reaction of intermetallics resulting in the development of the Exo-Melt(TM) process for melting and casting of intermetallics for a variety of structural applications. The Exo-Melt(TM) process allowed us to cast a wide variety of structural intermetallic parts using sand, centrifugal, and investment casting techniques, and a total of 15 000 kg of intermetallic parts were cast by the Exo-Melt(TM) process during 1995.

Hot extrusion at temperatures above T-alpha produces refined lamellar structures, whose microstructural features can be further controlled by subsequent heat-treatment at and above 900 degrees C. The mechanical properties of the alloys with lamellar structures depend on three factors: colony size, interlamellar spacing, and alloying additions. The tensile elongation at room temperature is strongly dependent on lamellar colony size, showing increasing ductility with decreased colony size. The strength at room and elevated temperatures is sensitive to interlamellar spacing, showing increasing strength with decreased colony spacing. The fracture toughness at room temperature can be substantially improved by heat-treatment at 1320 and 1350 degrees C. The tungsten addition at a level of 0 . 2%, improves the tensile strength, whereas the silicon addition at a level of 0 . 3%, reduces the castability of the TiAl alloys. TiAl materials produced by hot extrusion are much superior to those produced by conventional thermomechanical treatments.

Room-temperature tensile ductilities remained high over the entire pressure range tested: from 41% elongation to fracture at 5 . 7 x 10(-8) Pa pressure to 31% at 1 . 3 x 10(-3) Pa. Over this pressure range, the amount of transgranular fracture also remained quite high and scaled with the tensile ductility, increasing from similar to 60% in the samples with 31% ductility to similar to 70% in the specimen with 41% ductility. The ionization gage-used to measure hydrogen pressure-had a dramatic (deleterious) effect on the ductility of Ni3Al: at any given hydrogen pressure, the ductility measured with the ion gage on was about half to a quarter of that measured with the ion gage turned off. Accompanying this decrease in ductility was a change in fracture mode from predominantly transgranular to predominantly intergranular. The role of the ion gage is believed to be hot-filament-assisted dissociation of molecular H-2 into atomic H, which is quickly absorbed and embrittles the crack-tip regions. In the absence of any Al-induced embrittlement (either by filament-assisted dissociation of H-2 or by Al-induced reduction of H2O), polycrystalline Ni3Al is found to be quite ductile, with tensile elongations exceeding 40% and predominantly (>70%) transgranular fracture. Since these ductilities are similar to those of the most ductile B-doped alloys, the main role of boron is to suppress environmental embrittlement. Our results indicate that, at room temperature, low-pressure H-2 does not dissociate very efficiently into atomic H on the surfaces of Ni3Al and that, at comparable pressures, hydrogen is not as harmful to ductility as moisture (H2O).

With the exception of the Mn-containing alloy, all alloys showed solid solution strengthening following a 1 week/673 K vacancy removal anneal. Densities, lattice parameters and elastic constants were measured to determine vacancy concentrations as well as atomic size and modulus misfits. Although the strengthening could not be well described by established theories for dilute binary alloys, it could be reasonably well correlated with the magnitude of the atomic size misfit of the ternary alloying additions.

Influence of excess vacancies introduced by quenching from an elevated temperature is very important to the mechanical properties of B2 FeAl. Dot-like features and very small dislocation loops, probably formed by the interaction between gliding dislocations and excess vacancy clusters, were observed on the traces of dislocation movement in a thin foil of a water-quenched specimen. It is considered that the formation process of these dot-like features and small loops is closely associated with an excess-vacancy strengthening mechanism. Positive temperature dependence of yield stress is one of the hottest topics in B2 FeAl. It has been revealed by strain-rate change tests and stress relaxation tests that a recovery rate increases with increasing temperature in the range where temperature dependence of yield stress is positive (Stage II). It was observed in TEM that many superlattice dislocations had climb-dissociated configurations in Stage II, and that [111]-type dislocations were predominant even at the peak temperature when a specimen was deformed to a small strain. Based on these results, the climb-dissociation locking is believed to be the major cause for the strength anomaly. Copyright (C) 1996 Elsevier Science Ltd.

The major focus of the work is the development of a generally applicable finite element method for the simulation of both fixed interface and evolving porous interface problems. The available alternatives for coupling Darcy and non-Darcy models to the Navier-Stokes equations have been studied and evaluated in a mixed finite element framework. Questions regarding convergence of the finite element method for porous flow models have been addressed. Numerical experiments on simple flow geometries have revealed the shortcomings of both the Darcy and Brinkman models. Application of the more realistic models to practical, multidimensional, flow studies has also been demonstrated.

Problems arise not only due to the particular numerical scheme employed but also due to the resolution of the computational mesh. A comparative study of selected numerical schemes is presented herein, with regards to their ability to accurately predict the heating loads along the surface of the body. The grid dependency effects of these schemes are investigated. A parametric study is carried out and it is shown that the grid resolution for the accurate prediction of wall flux quantities is dependent on the free stream Mach and Reynolds numbers. A correlation is developed, for the generic class of blunt configurations studies herein, for predicting the grid requirements based on the free stream Mach and Reynolds numbers.

Asymptotic solutions for the stress field found at this type of interface corner are presented for an idealized but joint with rigid adherends and a thin, essentially semi-infinite, adhesive bond. Linear elastic, power law hardening, and perfectly plastic adhesive models are considered. A stress singularity of type sigma similar to Kr-delta (delta < 0) exists when the adhesive is either linear elastic or power law hardening. The impact of material properties on the order of the stress singularity delta and the effect of load level and bond thickness on the value of the interface corner stress intensity factor K are detailed. Slip theory is used to determined the asymptotic, interface corner stress field for a perfectly plastic adhesive. This solution indicates :hat there is a high level of hydrostatic tension, equal to 1.5 sigma(y), in the yielded material along the interface. The three asymptotic solutions are used to construct interface normal stress distributions that closely approximate full, finite element results for an idealization butt joint when small scale yielding conditions apply.

While a seemingly unlikely candidate for interactive use, simulated annealing is actually quite adaptable. With the ability to adjust basic algorithm parameters, an interactive system that allows a user to make tradeoffs between computational investment and solution optimality is possible. This concept is illustrated using a dependency visualization problem taken from software engineering. A formal model for capturing dependency information extracted from software systems is constructed for this purpose. Several simulated annealing strategies for generating and evaluating potential solutions within this model are then presented. A performance analysis of the basic simulated annealing components used by this method is discussed along with a comparison of different generation techniques. An integrated process which combines simulated annealing with other interactive tools is described. C1 UNIV CALIF DAVIS,DEPT APPL SCI,DAVIS,CA 95616.

Many of the features of this mouse model have suggested a premature or increased spontaneous frequency of apoptosis in thymocytes. Past work has documented an inability to establish cultured T cell lines, an abnormally high death rate of stimulated T cells in culture, and an increased sensitivity of T cells to the killing effects of ionizing radiations in the wst/wst mouse relative to controls. The experiments reported here were designed to examine splenic and thymic lymphocytes from the wasted and control mouse for signs of early apoptosis. Our results revealed enhanced expression of Rp-8 mRNA (which has been associated with apoptosis) in thymic lymphocytes and to a lesser extent in spinal cord in the wst/wst mouse relative to controls; expression of Rp-2 and Tcl-30 mRNA (also reported to be induced during apoptosis) were not detectable in spleen or thymus. Expression of Rp-2, Rp-8, and Tcl-30 mRNA in other affected tissues of the wasted mouse (brain and liver) were similar in the wasted mouse and controls. Thymus and spleen from the wasted mouse have reduced numbers of viable cells relative to controls. Higher spontaneous DNA fragmentation was observed in lymphocytes from the wasted mouse than in controls; however, gamma-ray-induced DNA fragmentation peaked at a lower dose and occurred to a greater extent in lymphocytes derived from the wasted mouse relative to controls. These results suggest that high spontaneous and gamma-ray-induced apoptosis in T cells of the wasted mouse may contribute to the mechanism underlying the observed lymphocyte and DNA repair abnormalities.

These events were analyzed to identify the direct causes, contributing factors, actions to mitigate the event, and the consequences of these events, The INEL also sought to determine the role played by the recent Quality Management Rule. Methods and Materials: The investigation teams were multidisciplinary and, depending on the nature of the event, included three or more team members with appropriate expertise in the areas of radiation oncology, medical physics, nuclear medicine technology, risk analysis, and human factors, The investigations focused on the general areas of causes of the event, mitigating actions, and corrective actions, Seven misadministration events were investigated by the teams during 1991 and 1992. Results: Results from the events investigated indicated that (a) the institutional traditions of some licensees contributed to the potential for misadministrations, (b) many misadministrations occurred primarily due to lack of procedures or procedures that were not clearly written, (c) some licensees in this study had not effectively implemented their Quality Management programs, and (d) limited involvement on the part of the Radiation Safety Officer and Authorized Users and changes in routine and unique conditions contribute to the potential for misadministrations. Conclusions: The project shows that licensees that have experienced misadministration events appear to lack comprehensive safety cultures, where all aspects of daily operations are shaped with patient and staff safety being the primary objective of all activities.

The circular footing is modeled by a pervious, weightless, rigid disk of negligible thickness. For a medium consisting of dense sand saturated by ground water, numerical solutions of the integral equations are obtained to reveal the variations of the impedance functions with the exciting frequency and the material parameters (permeability and Poisson's ratio). Comparison with the response of the dry soil is also discussed. In the rocking oscillation case, the presence of the ground water is found to influence the magnitude and shape of the impedance functions and may need to be considered in applicable soil-structure interaction problems. In the horizontal vibration case, however, marginal influence of the pore water is found to affect the response of the medium. C1 BROOKHAVEN NATL LAB,DEPT ADV TECHNOL,UPTON,NY 11973.

Our simulation studies indicate that Na+ and Cl- ions as a pair or as isolated infinitely dilute ions form strong solvation structures in SCW, even though the water-water hydrogen bonding is not affected. Within the context of the models we are using, there is strong indication of a high degree of Na+/Cl- ion pairing. C1 UNIV TENNESSEE,DEPT CHEM ENGN,KNOXVILLE,TN 37996.

Measured parameters are P, T, and tau (period of vibration). Fluids are injected into the U-tube at Constant P and T. Three or more reference fluids are used to calibrate the response of the instrument. Fluid mixtures are produced by pumping pure fluids into T-junctions on the upstream side of the U-tube using high accuracy syringe pumps. An automated syringe pump is used to maintain P at setpoint +/-0.01 MPa. T is controlled to +/-0.01 K using a closed-loop, electronic signal amplification/feedback system. For mixtures, a statistically significant number of measurements of tau are obtained to account for the effects of small heterogeneities in fluid composition (generally <0.005 X(i)). Typically, density data for 15 fluids can be obtained in a 6- to 8-h period. Considering all of the potential sources of error in the experimentation, conservative estimates of uncertainty are as follows: P, +/-0.02 MPa; T, +/-0.05 K; rho (pure fluids),+/-0.0005 g . cm(-3); and rho v(fluid mixtures), +/-0.0005 - 0.0010 g . cm(-3) C1 UNIV ALBERTA,DEPT GEOL,EDMONTON,AB T6G 2E3,CANADA.

The CP titanium alloys contain small amounts of oxygen. The mechanical properties of titanium, such as tensile and fatigue strengths, can be enhanced with oxygen additions, but care must be taken not to compromise toughness and ductility. Hydrogen, at concentrations below the commercially accepted limit, can also be detrimental to some of the mechanical properties of CP titanium, particularly under multiaxial stress and at both high and low strain rates. Hydrogen decreases ductility and creep resistance without, however, lowering the tensile strength. Although some of these effects result from the formation of a hydride phase, transmission electron microscope evidence indicates that residual interstitial hydrogen lowers the energy for dislocation generation and propagation. These hydrogen effects are more pronounced in oxygen alloyed titanium than in high purity titanium. (C) 1996 The Institute of Materials and ASM International.

The mechanical properties of these materials are reviewed. The tensile properties at low and high temperatures are described. At low temperature, very high tensile strengths can be achieved in deposition processed laminates and very high tensile ductilities can be achieved in roll bonded laminates by layer thickness refinement. At high temperature, superplasticity has been observed and agrees with predictions from constitutive creep relations. Damage critical properties (such as fracture toughness, fatigue, and impact behaviour) and damping can be superior to those exhibited by the component materials. The damage critical properties are strongly influenced by local delaminations at layer interfaces. Mechanisms responsible for many of the unique properties of LMCs have been proposed. The influence of processing, laminate architecture, and microstructure on these mechanisms and properties are described. (C) 1996 The Institute of Materials and ASM International.

This paper describes high resolution I-DDQ characterization and testing (from the sub-nA to mu A level) and outlines test hardware and software issues. The physical basis of I-DDQ is discussed. Methods for statistical analysis of I-DDQ data are examined, as interpretation of the data is often as important as the measurement itself. Applications of these methods to set reasonable test limits for detecting defective product are demonstrated.

Results of an electronic-based method that addresses compositional and magnetic disorder, as well as atomic short-range order and energetics are discussed. The approach allows a system-dependent microscopic understanding of the interplay of chemical, magnetic, and displacive effects, and a direct comparison to diffuse scattering experiments. The discussion will be given in the context of total-energy calculations for various magnetic states in chemically disordered and ordered Ni Fe alloys, emphasizing the importance of exchange-splitting, and the implication for the phase stability in Ni-Fe system.

As shown in previous studies, this leads to changes in alloy density that arise from crystallographic modulations of the composition, with nickel behaving as one species while iron and chromium together behave as a separate species. The compositional oscillations are large in both magnitude (25-50% Ni) and in extent, varying from several hundred Angstrom at 400 degrees C to about 1 mu m at 625 degrees C and 2 to 3 mu m at 675 degrees C. In this paper three experimental methods are shown that have been developed to allow visualization of the decomposition on a large scale. The decomposition is thought to be the result of the combined action of (1) a natural instability in the Invar regime, (2) radiation-enhanced diffusion, and (3) radiation-induced segregation, the three processes cooperating to produce a new form of radiation-induced self-organization.

Previous research addressing this problem in multi-robot systems has largely focused on issues of efficiency, while ignoring the real-world situated robot needs of fault tolerance and adaptivity. This paper addresses this problem by developing an architecture called L-ALLIANCE that incorporates task-oriented action selection mechanisms into a behavior-based system, thus increasing the efficiency of robot team performance while maintaining the desirable characteristics of fault tolerance and adaptivity. We present our investigations of several competing control strategies and derive an approach that works well in a wide variety of multi-robot task-oriented mission scenarios. We provide a formal model of this technique to illustrate how it can be incorporated into any behavior-based system.

More specifically, a human-computer boxing game system is developed in a graphical environment. One boxer is controlled by a human through a motion tracking system, while the other is controlled by a motion planning algorithm. The planner has a defensive mid an offensive strategies. The defensive strategy tries to move one of the forearms between the opponent's fist and its body, while the offensive strategy locates an exposed part of the opponent's body and throws a punch at it To achieve an interactive operation, the motion planner considers only kinematic and geometric constraints during the search. This project is also aimed at integrating a planner with an actual robot,and investigating associated technological bottlenecks. C1 Sandia Natl Labs, Albuquerque, NM 87185 USA.

A key research issue in these problems is that of sensor placement - determining where sensors should be located to maintain the targets in view. In complex applications involving limited-range sensors, the use of multiple sensors dynamically moving over time is required. In this paper, we investigate the use of a cooperative team of autonomous sensor-based robots for the observation of multiple moving targets. We focus primarily an developing the distributed control strategies that allow the robot team to attempt to minimize the total time in which targets escape observation by some robot team member in the area of interest. This paper first formalizes the problem and discusses related work. We then present a distributed approximate approach to solving this problem that combines low-level multi-robot control with higher-level reasoning control based on the ALLIANCE formalism. We analyze the effectiveness of our approach by comparing Ct to three other feasible algorithms for cooperative control, showing the superiority of our approach for a large class of problems.

Topics include the need for ''active'' protection systems, system requirements, design criteria, and means of archieving and assessing acceptable reliability.

For each effect t(m) = , where t(m) is the median elapsed time to death with the specified effect after intake, (d) over bar is the time-weighted average absorbed radiation dose-rate to the target organ, Y, is the median distribution coefficient, and s is the negative slope parameter. Using maximum likelihood survival regression methods, s was found to be 1/3 for alpha radiation and 2/3 for beta radiation. The relationships of competing risks of death associated with radiation injury, radiation-induced cancer, and natural aging after initial exposure or intake are graphically portrayed using three-dimensional illustrations of these dose-rate/time/response surfaces. At the higher dose rates (larger organ burdens of radionuclide) the principal deleterious effects are those associated with radiation-induced injury while at intermediate dose rates radiation-induced cancer predominates. For cancer induction, lower dose rates have a higher relative dose effectiveness than higher dose rates (inverse dose-rate effect) for either low LET beta radiation or high LET alpha radiation. However, at the lower dose rates the long latency time required for development of radiation-induced cancer may exceed natural life span, yielding a life-span effective threshold for death associated with radiation-induced cancer at a lifetime cumulative absorbed dose to the target organ of from about 0.08 to 1.4 Gy for alpha irradiation or from about 28 to 130 Gy for beta irradiation. The beagle results were scaled to predict human bone cancer risks for internally-deposited Ra-226 and the predicted life-span effective threshold of about 2.1 Gy agreed well with the U.S.A. human Ra-226 data. The predicted occurrence of human lung cancer from inhaled (PuO2)-Pu-239 yielded a life-span effective threshold of about 1.4 Gy..

This ratio is determined for a selected detector location, gamma energy and activity distribution. If the spatial distribution of the activity is unknown, however, the resulting calculated assessment of the activity from a single detector may contain a high degree of uncertainty. In addition, the optimal location of the measurements becomes a function of the background radiation, the amount of activity present and the desired statistical confidence of the result. If a set of N measurements is considered an N vector response, the incorporation of multiple detector measurements can reduce the uncertainty of the calculated assessment. The multiple detector calculations are performed by applying dimensional measurement space and a unit response set to the problem of assessing and optimizing multiple independent detector measurements of various waste containers. The associated errors of multiple measurements are calculated for various detector placement configurations. The calculations indicate that multiple detector measurements and optimal placement of the measurements combined with appropriate mathematical techniques significantly reduce the assessment uncertainties due to lack of knowledge of the spatial distribution of activity.

While advantages of such techniques are increased analytical efficiency and cost savings, the sensitivity of measurements decreases because it is inversely proportional to the number of samples in the pools. Consequently, uncertainties in estimates of dose and risk which are based on the results of pooled samples increase as the number of samples in the pools increases in all applications. However, sensitivities may not be seriously degraded, for example, in urinanalysis, if the samples in the pools are of known time duration, or if the fraction of some attribute of the grab urine samples to that in a 24-hour composite is known (e.g., mass, specific gravity, creatinine, or volume, per 24-h interval). This paper presents square and cube pooling schemes that greatly increase throughput and can considerably reduce analytical costs (on a sample basis). The benefit-cost ratios for 5x5 square and 5x5x5 cube pooling schemes are 2.5 and 8.3, respectively. Three-dimensional and higher arrayed pooling schemes would result in even greater economies; however, significant improvements in analytical sensitivity are required to achieve these advantages. These are various other considerations for designing a pooling scheme, where the number of dimensions and of samples in the optimum array are influenced by: 1) the minimal detectable amount (MDA) of the analytical processes, 2) the screening dose-rate requirements, 3) the maximum masses or volumes of the composite samples that can be analyzed, 4) the information already available from results of composite analysis, and 5) the ability of an analytical system to guard against both false negative and false positive results. Many of these are beyond the scope of this paper but are being evaluated. RP Sun, LC (reprint author), BROOKHAVEN NATL LAB,UPTON,NY 11973, USA.

The hot particles had maximum dimensions of 650 mu m and maximum beta energies of 0.97, 0.46, 0.36, and 0.32 MeV. Absorbers were used to obtain the dose at different depths for each dosimeter. Measurements were made using exoelectron dosimeters, an extrapolation chamber, NE Extremity Tape Dosimeters(TM)**, Eberline RO-2 and RO-2A(TM) survey meters, and two sets of GafChromic(TM) dye film with each set read out at a different institution. From these results the dose was calculated averaged over 1 cm(2) of tissue at 18, 70, 125, and 400 mu m depth. Comparisons of tissue-dose averaged over 1 cm(2) for 18, 70, and 125 mu m depth based on interpolated measured values, were within 30% for the GafChromic(TM) dye film, extrapolation chamber, NE Extremity Tape(TM) dosimeters, and Eberline RO-2 and 2A(TM) survey meters except for the hot particle with 0.46 MeV maximum beta energy. The results for this source showed differences of up to 60%. The extrapolation chamber and NE Extremity Tape(TM) dosimeters under-responded for measurements at 400 mu m by about a factor of 2 compared with the GafChromic(TM) dye films for two hot particles with maximum beta energy of 0.32 and 0.36 MeV which each emitted two 100% 1 MeV photons per disintegration. Tissue doses determined using exoelectron dosimeters were a factor of 2 to 5 less than those determined using other dosimeters, possibly due to failures of the equipment.

Hanford mini-swine were exposed to localized doses from 0.2 to over 600 Gy (averaged over 1 cm(2) at 70 mu m depth) from isotopes having maximum beta particle energies from about 0.3-3 MeV. The incidence of erythema and scabs (indicating ulceration) were scored routinely for up to 71 days post-irradiation. The responses followed normal probability distributions, and thus, no true threshold could be defined. Ten and 50% incidence rates were deduced using probit analyses. The lowest dose which produced 10% incidence was about 1 Gy for exposures to Yb-175 (0.5 MeV maximum energy) beta particles. The severity of lesions was estimated by analyzing the results in terms of their diameters and persistence. From preliminary considerations of the probability of induction, size, and persistence of acute lesions, a special limit for hot particle exposures in the range of 5-50 Gy may be reasonable, with an action level between about 1 Gy and the limit.

The programs provide Monte Carlo solution of linear time-independent coupled electron/photon radiation transport problems. A simple multi-layer slab model of a low voltage curtain electron beam was constructed using the ITS/TIGER code and it consistently accounted for about 71% of the actual dose delivered across the voltage range of 100 - 300 kV. The differences in calculated values was principally due to the 3D hibachi structure which effectively blocks 22% of the beam and could not be accounted for in a 1D slab geometry TIGER model. A 3D model was constructed using the ITS/ACCEPT Monte Carlo code to improve upon 1D slab geometry simulations. Faithful reproduction of the essential geometric elements involved, especially the window support structure, accounted for 86-99% of the dose detected by routine dosimetry.

A relatively thin imaging layer of a photo-cross-linking resist is spun over a thicker layer of hard-baked resist that functions as a planarizing layer and antireflective coating. Photoinduced acid generation and subsequent heating crosslinks and renders exposed areas impermeable to an aminodisilane that reacts with the unexposed regions. Subsequent silylation and reactive ion etching afford a positive-tone image. The use of disilanes introduces a higher concentration of silicon into the polymer than is possible with silicon reagents that incorporate only one silicon atom per reactive site. The higher silicon content in the silylated polymer increases etching selectivity between exposed and unexposed regions and thereby increases the contrast. Additional improvements that help to minimize flow during silylation are also discussed, including the addition of bifunctional disilanes. We have resolved high aspect ratio, very high quality 0.20 mu m line and space patterns at 248 nn with a stepper having a numerical aperture (NA)=0.53, and have resolved less than or equal to 0.15 mu m line and spaces at 13.5 nm.

This can be achieved by mounting freestanding, thin film capacitors directly onto ICs as part of a chip-scale packaging approach. These ''applique'' capacitors utilize a chemically-prepared PLZT dielectric, which is nominally 1 mu m thick. The small size and weight of applique capacitors can be used to improve packaging efficiency. Applique capacitors, which are initially fabricated on silicon wafers, have high permittivity(epsilon congruent to 1000), low loss (tan delta congruent to 0.01) and high breakdown strength (E-B congruent to 1 MV/cm) and leakage resistance (rho > 10(14) Omega-cm @ 125 degrees C). Various processes being developed to remove the capacitors from the silicon substrate and reattach them to ICs is described. In addition, a concept for interconnecting the capacitors using a repatterning process is discussed. RP Garino, TJ (reprint author), SANDIA NATL LABS,POB 5800,ALBUQUERQUE,NM 87185, USA.

It is found that the mean-time-to-failure (life-time or t(f)) of the capacitors shows a power law dependence on applied voltage of the form t(f) proportional to V-n (n similar to 4-5). The capacitor Life-time also (t(f)) exhibits a temperature dependence of the form t(f) proportional to exp(E-a/kT), with an activation energy of similar to 0.8 eV. The steady-state leakage current in these samples appears to be bulk controlled. The voltage, temperature, and polarity dependence of the leakage current collectively suggest a leakage current mechanism most similar to a Frenkel-Poole process. The Nb-doped PZT films exhibit superior life-time and leakage current to the undoped PZT films. This result can be explained based on the point-defect chemistry of the PZT system. Finally, the results indicate that the Nb-doped PZT films meet the essential requirements for decoupling capacitor applications.

This paper describes the effect of Cr2N precipitation on the mechanical, corrosion, and abrasive wear properties of a high-nitrogen austenitic stainless steel, nominally Fe-19Cr-5Mn-5Ni-3Mo-0.02C-0.7N. In the annealed state, Cr-rich nitrides (Cr2N) precipitate sequentially as intergranular, cellular, and finally, intragranular precipitates. Cold working, prior to aging, increases grain boundary and intragranular precipitation kinetics, but retards cellular phase formation. Nitride precipitation has only a minor influence on the yield and ultimate tensile strength of annealed materials, but causes embrittlement which is enhanced by high strain rate conditions such as impact testing and by the accelerated precipitation kinetics associated with prior deformation. Nitride precipitation results in sensitization which is also accelerated by prior deformation. The degree of sensitization, as measured by electrochemical potentiokinetic reactivation (EPR) testing, correlates to intergranular, cellular, and intragranular Cr-depletion. Although the degree of sensitization is defined by both the Cr-minimum and width of Cr-depleted region, a Cr level below approximately 14 wt% is required for sensitization. Precipitation also results in a greater corrosion susceptibility as determined by potentiodynamic polarization scans. The wear behavior of the 0.7 wt% N alloy is little affected by the precipitation of Cr2N since the volume fraction and size (compared to the abrasive) of the Cr2N precipitates is insufficient to alter the wear resistance of the alloy.

The rest of the system, upon cooling, crystallized according to the well-known CaO-Al2O3-SiO2 phase diagram. It was seen that if chlorine is present in sufficient amounts (greater than 4.9 wt%), the chlorine phase constitutes 92 wt% of the final slag. Also when the chlorine phase was less than 92 wt% in the final slag, the recovery of chlorine exceeded 90%. For comparison, CaO-Al2O3-SiO2 = 48-12-40 wt% representing an ironmaking slag, was mixed with 10.0 wt% CaCl2 and also similarly heated and characterized after cooling. The phases observed were 2CaO . Al2O3 . SiO2 and two new chlorine phases, all of which were glassy. C1 MIT,DEPT MAT SCI & ENGN,CAMBRIDGE,MA 02139.

The first experiment (Jerusalem) utilizes single-pulse shock tube methods to measure the isomerization rate of CMA to chloroallene. In addition, equilibrium constants can be estimated at similar to 1200 K. The second experiment (Argonne) monitors Cl-atom formation at temperatures above similar to 1150 K. Absolute yield measurements have been performed over the 1200-1700 K range and indicate that two decomposition channels contribute to CMA destruction, namely, Cl fission and HCl elimination. The results show that the branching fraction between processes is temperature dependent. Therefore, direct Cl-atom fission is accompanied by molecular elimination, undoubtedly giving HCl and one or more isomers of C3H2. MP2 6-31G(d,p) ab initio electronic structure calculations have been used to determine vibration frequencies and moments of inertia for three C3H3Cl isomers. Using these quantities, the experimental equilibrium constants required that Delta H-0(0)(CH2Cl-C=CH reversible arrow CHCl=C=CH2) = -0.24 kcal mole(-1). A potential energy. surface pertinent to the present system has been constructed, and RRKM calculations have been carried out in order to explain the isomerization rates. The isomerization data can be explained with E(0) = 52.3 kcal mole(-1) and [Delta E(down)] = 225 cm(-1). Subsequent semi-empirical Tree and RRKM-Gorin modeling of the Cl atom rate data require E(0) = (67.5 +/- 0.5) kcal mole(-1) with a [Delta E(down)] = (365 +/- 90) cm(-1). This suggests a heat of formation for propargyl radicals of (79.0 +/- 2.5) kcal mole(-1). C1 ARGONNE NATL LAB,DIV CHEM,ARGONNE,IL 60439. ARGONNE NATL LAB,DIV MATH & COMP SCI,ARGONNE,IL 60439.

We have previously developed a gated manufacturable emitter process which uses fillets as emitters. Since tips have higher field enhancement then fillets we have tried to adapt our process to incorporate tip emitters. Two different approaches have been developed to try to achieve this goal. The first approach employs a sputter etch to form a tip on the end of a spike. Unfortunately, the tip formed is not sufficiently sharp enough to reduce the turn on voltage. In the second approach, the corners of a mold are sharpened during the deposition of the spacer material. The emitter material is then deposited and following the removal of the spacer, a very sharp tip remains. RP Fleming, JG (reprint author), SANDIA NATL LABS,MS 1084,POB 5800,ALBUQUERQUE,NM 87185, USA.

Using experimental data for this creep in different materials, it is demonstrated that the flow process in H-D creep may be dislocation glide plus climb with the climb being rate-controlling under a constant dislocation density determined by the magnitude of the Peierls stress. It is shown that the occurrence of the transition from power law creep to Harper-Dorn creep at the Peierls stress may result from the change in the dependence of the dislocation density on the applied stress in power law creep but on the Peierls stress in H-D creep.

The spherical particulate composite exhibited a slightly lower yield strength and work hardening rate but a considerably higher ductility than the angular counterpart. SEM fractographic examination showed that during tensile deformation the spherical composite failed through void nucleation and linking in the matrix near the reinforcement/matrix interface whereas the angular composite failed through particle fracture and matrix ligament rupture. FEM results indicate that the distinction between the failure modes for these two composites can be attributed to the differences in the development of internal stresses and strains within the composites due to particle shape.

Its very fast uptake and clearance from the brain contrasts with that of methylphenidate, another drug that inhibits the DA transporter. Methylphenidate clears from the brain at a much slower rate and is less addictive than cocaine. We postulate that periodic and frequent stimulation of the dopaminergic system secondary to chronic use of cocaine favors activation of a circuit that involves the orbitofrontal cortex, cingulate gyrus, thalamus and striatum. This circuit is abnormal in cocaine abusers and we postulate that its activation by cocaine perpetuates the compulsive administration of the drug and is perceived by the cocaine abuser as a intense desire resulting in the loss of control over the drive to take more cocaine.

Stress relaxation test data are reported here for the adhesive used in those joint tests. This adhesive displays highly nonlinear, stress level-dependent viscoelasticity at stress levels approaching the adhesive's yield strength, and significant stress relaxation occurs once the adhesive yields. For example, when loaded to yield, stress levels can decrease by 30% over a period of 30 min even at temperatures of more than 100 degrees C below the adhesive's glass transition temperature. Consequently the influence of residual stress on the butt joint strength could be much smaller than would be predicted by a linear analysis. The peak stresses in an adhesive joint, in the yield zone at the interface corner where failure initiates, can decay significantly when given sufficient time. The temperature dependence of the interface corner fracture toughness K-fc, a material constant that has been shown to characterize the effect of bond thickness on butt joint strength, is also discussed. The observed variation in K-fc with temperature is compared with the variations exhibited by the adhesive's yield strength and plane strain fracture toughness.

Temperatures in these studies ranged from 25 to 700 degrees C. The Np-Zr specimens were characterized as consisting of different combinations of Np, Zr and NpZr2 phases at the different temperatures. The results obtained for this Zr-rich portion of the phase diagram diagram suggest that there is not a continuous mutual solubility between gamma-Np and beta-Zr, as known to exist in the U-Zr binary system. The solubility of Zr in gamma-Np was estimated to be ca.4% at 600 degrees C. Only the alpha form of Zr was observed in these studies, indicating that there was insufficient Np dissolved in the Zr phase to stabilize its beta phase below the normal alpha-beta transition temperature of 850 degrees C. The hexagonal NpZr2 was detected up to 550 degrees C, above this temperature it appeared to decompose. Diffraction lines for the alpha, beta and gamma forms of Np were observed as a function of the temperature. lines for Np disappeared above 650 degrees C, presumably because of its ''localized'' melting in micro-domains.

The electrochemical reduction of these materials to gaseous products has been studied in a synthetic waste mixture. The effects of electrode materials, cell design, and other experimental parameters have been investigated. Lead was found to be the best cathode material in terms of current efficiency for the reduction of nitrate and nitrite in the synthetic mix. The current efficiency for nitrite and nitrate removal is improved in divided cells due to the elimination of anodic oxidation of nitrite. Operation of the divided cells at high current densities (300-600 mA cm(-2)) and high temperatures (80 degrees C) provides more efficient reduction of nitrite and nitrate. Nearly complete reduction of nitrite and nitrate to nitrogen, ammonia, or nitrous oxide was demonstrated in 1000 h tests in a divided laboratory electrochemical flow cell using a lead cathode, Nafion(R) 417 cation exchange membrane, and oxygen evolving DSA(R) or platinum clad niobium anode at a current density of 500 mA cm(-2) and a temperature of 70 degrees C. Greater than 99% of the nitrite and nitrate was removed from the synthetic waste mix batch in the 1000 h tests at an overall destruction efficiency of 55%. The process developed shows promise for treating large volumes of waste. C1 WESTINGHOUSE SAVANNAH RIVER CO,SAVANNAH RIVER TECHNOL CTR,AIKEN,SC 29808.

Over the period encompassed by these observations, the boundary layer evolved from a well-mixed cloud-capped boundary layer overlying a stable cloudy surface layer to a shallower well-mixed boundary layer with a single upper cloud deck and a clear, diminished, stable surface layer. The model was able to reproduce the observed profiles of the liquid water content, cloud-base height, radiative heating rates, and the mean and turbulence variables over the period of observation fairly well. The formation and eventual dissipation of the surface cloud feature over the period of the simulation was found to be caused by the formation of a stable surface layer as the modeled air mass moved over the relatively cold Beaufort Sea region. Condensation occurred as heat in the surface layer was transported downward toward the sea surface. Eventual dissipation of the surface cloud layer resulted from the transport of moisture in the surface layer downward toward the sea surface. The results show that the subsidence was the major influence on the evolution of the cloud-top height but was not a major factor for dissipation of either cloud layer during the simulation.

Photothermal ionization spectroscopy of samples quenched from 673 K reveals two sets of hydrogenic lines with ground state binding energies of 9.15 and 10.05 meV. The line intensity ratios between corresponding transitions (1s-np) of the two hydrogenic series follow a Boltzmann dependence. This shows that the two series belong to the same impurity complex with a split ground state. Taking into account the crystal growth conditions together with the changes in the donor concentration deduced from variable temperature Hall effect measurements, we conclude that arsenic and substitutional copper form the new acceptor complex A(Cu-s,As) since copper is the only fast-diffusing species at this low annealing temperature. This complex is expected to have C-3 upsilon symmetry in agreement with preliminary piezospectroscopy measurements. (C) 1996 American Institute of Physics.

In agreement-with experimental microcontact measurements made on individual junctions, the networks are assumed to contain randomly distributed microjunctions of two types: (1) electrically active with highly nonlinear current-voltage (I-V) characteristics and (2) ohmic, i.e., with linear I-V characteristics. Effects of the ohmic grain boundaries in the network are simulated for various concentrations and resistivities. Shapes of the simulated I-V characteristics and current dependence of the coefficient of nonlinearity of the network are in good agreement with Chose experimentally observed for thin varistor samples and in the measurements employing various surface electrode patterns. It is found that the breakdown voltage of the networks increases with the number of the ohmic grain boundaries, except when their resistivity is so low that it becomes comparable with that of the ZnO grains. The maximal value of the coefficient of nonlinearity of the network is shown to be insensitive to the presence of the ohmic grain boundaries, regardless of their resistivity and concentration.

At room temperature, Pr18Co82 exhibits poor coercivity and remanence, 600 Oe and 2.9 kG, respectively. Pr18Co81C exhibits relatively superior remanence, 7.7 kG, but poor coercivity, 2.7 kOe, while Pr18Co76C6 exhibits the opposite trend, B-R = 4.5 kG and H-ci = 12 kOe. The main phase present in all samples, PrCo5, has basically the same character and morphology for all three samples and shows no evidence of intragranular carbon, which is demonstrated to reside in the impurity phases. The superior coercivity found in Pr18Co76C6 is attributed to a previously unknown triclinic phase, Pr3Co4Cx (x approximate to 3-4) that appears to undergo a magnetic-nonmagnetic transition with increasing temperature around T = 80 K. The variety of magnetic properties exhibited by each sample is due to the variety of minor phases present in each sample, which may be a product of the effect that carbon has on the solidification rate of the parent alloy.

Silicon substrates were coated with thin films of amorphous carbon using a vacuum are technique. The carbon-coated silicon substrates were pretreated with a methane-rich plasma at relatively low temperatures and were subsequently exposed to the diamond nucleation conditions. The significance of the pretreatment on the diamond nucleation density was examined by varying the methane concentration, chamber pressure, and exposure time. Scanning electron microscopy demonstrated that densely packed spherical nanoparticles on the pretreated surfaces played the role df diamond nucleation seeds. Raman spectroscopy analysis showed that the nucleation seeds consisted of nonhydrogenated carbon and that their structure was influenced by the pretreatment conditions. Transmission electron microscopy revealed that the nucleation seeds comprised disordered graphitic carbon and ultrafine diamond crystallites. Submicrometer films of good quality diamond possessing significantly higher nucleation densities (similar to 5 x 10(10) cm(-2)) were grown from nanoparticles produced under optimum pretreatment conditions. The enhancement of the diamond nucleation density is mainly attributed to the formation of a large number of nanoparticles, which provided sufficient high-surface free-energy sites for diamond nucleation, in conjunction with their high etching resistance to atomic hydrogen stemming from the significant percentage of sp(3) atomic carbon configurations, as evidenced by the presence of nanocrystalline diamond in the nanoparticle structure.

Seventy-two Sprague-Dawley rats of each sex, 6-7 weeks old, were divided into six groups (12 of each sex per group) and gavaged with 0, 0.003, 0.01, 0.03, 0.1 or 0.3 mg kg(-1) sulfur mustard in sesame oil for 5 days a week for 13 weeks. No dose-related mortality was observed. A significant decrease (P > 0.05) in body weight was observed in both sexes of rats only in the 0.3 mg kg(-1) group. Hematological evaluations and clinical chemistry measurements found non consistent treatment-related effects at the doses studied. The only treatment-related lesion associated with gavage exposure upon histopathological evaluation was eipthelial hyperplasia of the forestomach of both sexes at 0.3 mg kg(-1) and of males at 0.1 mg kg(-1). The hyperplastic change was minimal and characterized by cellular disorganization of the basilar layer, apparent increase in mitotic activity of the basilar epithelial cells and thickening of the epithelial layer due to the apparent increase in cellularity. The estimated no-observed-effect level (NOEL) for sulfur mustard in this 90-day study was 0.1 mg kg(-1) day(-1) when administered orally.

The hydrogenation of cyclohexene to cyclohexane was studied at about 1.5 atm total pressure of H-2 and as a function of temperature in the 313-333 K range in liquid cyclohexene. The hydrogenation rate of cyclohexene on a clean Pt surface increased with the increasing circulation velocity of the liquid, indicating that the reaction rate was controlled by hydrogen diffusion to the surface. When the surface reaction rate was reduced by the deposition of hydrocarbon fragments on the platinum surface, the rate of cyclohexene hydrogenation became independent of hydrogen diffusion and became controlled by the kinetics of the surface reaction. The estimated activation energy of the reaction is 6 kcal/mol for cyclohexene hydrogenation on a platinum foil that was partly covered with carbonaceous deposits. (C) 1996 Academic Press, Inc.

The Mo weight loading was varied to study the effect of loading on the pyridine hydrodenitrogenation activity. It was found that the specific activity of sulfided molybdena on the P25 titania decreased monotonically with increasing loading. On the other hand, the microroughened titania did not show such a fall off in activity; furthermore its specific activity was over an order of magnitude greater than that of the P25-supported sample. The rather surprising behavior of MoS2 supported on microroughened titania can be related to the structure of the catalyst. On the microroughened titania, the MoS2 sheets are curved with radii of curvature ranging from 2-5 mm. These strained MoS2 layers could lead to the formation of unique catalytically active sites in the basal plane of MoS2, not otherwise obtained on conventional supports. (C) 1996 Academic Press, Inc.

Specifically, a modified Filinov transformation of an initial value representation of the semiclassical propagator has been used to approximate the Green's function. Numerical application of this trajectory-based semiclassical approximation to a simple one-dimensional (barrier transmission) test problem shows the approach to be an accurate description of the reaction probability, even some ways into the tunneling regime.

The diatomic molecules were modeled to be energetically similar to nitric oxide, NO, which is a detonable material when in the condensed phase. The system was intended to simulate an experiment devised to examine the initiation phase of a detonation of liquid NO stimulated by impact with a high-speed flyer plate. Classical trajectories were computed for six different cluster sizes, from 4 molecules to 50, and the clusters were directed into a wall at five different impact speeds ranging from 3.0 to 11.8 km s(-1). The interatomic forces used for the computations were based on a modification of an empirical potential suggested by Tersoff. The characteristics of the products (O-2, N-2, NO, and N and O atoms) are examined, as well as the dynamic features of the collisions of the clusters with the wall. The conditions of the cluster impacts produced atom densities that were nearly triple the initial density of the clusters. The reactions in the n=50 cluster are complete in less than 300 fs. These conditions are unusual for studies of chemical reactions so that the many-body effects are expected to be important. They are conditions experienced in the initiation of explosive detonations.

On the basis of the observed maximum kinetic energy for the formation of HS + CH2CH2SH, a value of 74 +/- 2 kcal/mol is derived for the bond dissociation energy of HS-CH2CH2SH at 0 K [D-0(HS-CH2CH2SH)]. Angular distribution measurements for SH yield an anisotropic parameter beta=-0.4+/-0.1 for the HS+CH2CH2SH channel, indicating that the C-S bond fission is fast with respect to molecular rotation. The energetics for the formation of HS+CH2CH2SH from HSCH2CH2SH have been investigated using the Gaussian-2 (G2) and G2(MP3) ab initio quantum chemical procedures. The G2/G2(MP3) calculations give a prediction of 72.5 kcal/mol for D-0(HS-CH2CH2SH), in excellent agreement with the experimental value.

The viscosity calculated by our nonequilibrium molecular dynamics simulations is in good agreement with that obtained from our equilibrium molecular dynamics simulations via the Green-Kubo relation and with that obtained by Mundy ct al. [J. Chem. Phys. 102, 3776 (1995)] using the same potential model at the same state conditions. Additionally, the viscosity calculated by nonequilibrium molecular dynamics is in very good agreement with experimental results for n-decane. The algorithm used for the equilibrium molecular dynamics simulations is an application to alkanes of the multitime step Nose dynamics algorithm developed by Tuckerman and Berne. For the nonequilibrium molecular dynamics simulations, an extension of the multitime step method is derived for the nonequilibrium equations of motion describing planar Couette flow with Nose thermostat. The contributions of the intramolecular interactions to the stress tensor and its relaxation have been analyzed; the bond stretching motions play a dominant role in the short-time behavior of the atomic stress-stress correlation.

The temperature dependence of the surface product distribution, in the range of 300-650 K, is derived from SXPS core-level and valence-band spectra and compared to known gas-phase product distributions. It is found that both Ga and As chlorides are formed at room temperature. Following reaction at temperatures above similar to 400K, no Cl remains on the surface. Instead, for temperatures up to similar to 600 K an As overlayer is formed, whereas reaction at similar to 650 K leads to the stoichiometric removal of Ga and As. These findings indicate that there is a direct correlation between the surface and gas-phase product distributions. (C) 1996 American Institute of Physics.

The r-particle CCF is approximated by a product of effective two-particle CCFs, accounting for nearest-neighbor correlations and next-to-nearest-neighbor correlations. For hard-sphere chain fluids (HSCF), the density dependence for nearest-neighbor effective two-particle CCFs is determined by the equation of Tildesley-Streett for hard-sphere dumbbells and that for next-to-nearest-neighbor effective two-particle CCFs by computer-simulation results for hard-sphere trimers. The final equation of state has a simple form which gives compressibility factors and second virial coefficients for homonuclear HSCFs covering a wide range of chain length (up to r=201) in excellent agreement with computer simulations. Satisfactory comparisons are also obtained between predicted and computer-simulation results for homonuclear HSCF mixtures, HSCFs containing side-chains and rings, and heteronuclear HSCFs (copolymers).

Molalities of the reference electrolyte ranged from about 0.5 mol . kg(-1) to greater than 6 mol . kg(-1). The ion-interaction model of Fitter gave an excellent description of the experimental results when the solutions were treated as mixed-electrolyte systems resulting from partial ionization of HSO4-(aq). A simple polynomial model for the temperature dependence of the ion-interaction parameters is sufficient to reproduce the experimental results. When calculated as stoichiometric activity coefficients for 1-2 charge types, the resulting quantities are quite small, especially when compared with activity coefficients based on the assumption of a 1-1 charge type. The activity coefficients are consistent with limited dissociation of the hydrogensulfate anion which decreases with increasing temperature.

These measurements encompass the water activity ranges a(w) of 0.9902 less than or equal to a(w) less than or equal to 0.9783 and 0.9902 less than or equal to a(w) less than or equal to 0.9741, respectively. Molality analyses used for previous solubility, density (J. Solution Chem. 1988, 17, 499-517), and isopiestic measurements (J. Solution Chem. 1990, 19, 525-541) for Lu-2(SO4)(3)(aq) from this laboratory were found to be slightly high due to absorption of water vapor during the analyses, as was that of the NaCl(aq) isopiestic reference standard from incomplete drying during the dehydration analysis. Those results were corrected and combined with the present isopiestic measurements to yield recommended values of osmotic coefficients, water activities, and mean activity coefficients of Lu-2(SO4)(3)(aq), and the solubility and thermodynamic solubility product of Lu-2(SO4)(3) . 8H(2)O(cr), all at the temperature T = 298.15 K. A detailed study was made of the extent of the retention of water by NaCl(s) during drying and of absorption of water vapor by Lu-2(SO4)(3)(s) and other anhydrous rare earth sulfates as they are weighed in air. Methods were developed for accurately correcting each total mass of rare earth sulfate for absorbed water. In addition, isopiestic measurements were performed for H2SO4(aq) in the molality region where previous isopiestic results were found to be somewhat discordant in the critical review by Clegg et al.

Data were collected on the ultimate tensile strength, modulus of elasticity, and ultimate tensile strain of the composite samples prepared. The results show that the aligned fibers were approximately twice as effective as randomly oriented fibers at stiffening and strengthening the composite in the alignment direction.

We identify the material parameters required and outline experimental and theoretical methods for their determination. This formalism is then used to calculate the development of cure stresses for an epoxy wherein the glass transition temperature exceeds the cure temperature during the reaction.

This extension of the homogenization technique increases the accuracy of numerical simulations for high strain-rate loadings. It is particularly important for any dynamic loading in which shock waves might be produced, including crash safety, armor, and munitions applications. Examples illustrate that elastic nonlinearity can make substantial contributions at strains of only a few percent. These contributions are greatest during post-yield inelastic deformation. The micromechanics-based homogenization technique is shown to facilitate use of an efficient approximate treatment of elastic nonlinearity in composites with isotropic matrix materials.

This approach retains the philosophy of Aboudi's Method of Cells but is indeed a finite element (FE) based approach. The equations of equilibrium are applied to a representative volume model (RVM) and a unified method of homogenization (UMH) of micromechanical effects is presented. The method as developed here can be applied to find the homogenized properties of any representative volume model that meets the requirements discussed. In this paper. we first apply it to the analysis of grinding wheels, a ''three'' constituent isotropic material, wherein the void is treated as a material having volume property only. The equations, which are derived for an orthotropic material, are then specialized to fiber reinforced composites and the results are compared to Aboudi's and others. Several interesting points arise regarding the FE ''load vector'' for specialists that typically work in developing FE methods and codes.

Collisional processes between particles of different species are treated through the concept of a grid-based ''collision field,'' which can be particularly efficient for multi-dimensional applications. In this method, particles are scattered using a force which is determined from the moments of the distribution functions accumulated on the grid. The form of the force is such to reproduce the multi fluid transport equations through the second (energy) moment. Collisions between particles of the same species require a separate treatment. For this, a Monte Carte-like scattering method based on the Langevin equation is used. The details of both methods are presented, and their implementation in a new hybrid (particle ion, massless fluid electron) algorithm is described. Aspects of the collision model are illustrated through several one- and two-dimensional test problems as well as examples involving laser produced colliding plasmas. (C) 1996 Academic Press, Inc.

Although the equation is a derivative of lattice gas automata, it may be interpreted as a Lagrangian finite-difference method for the numerical simulation of the discrete-velocity Boltzmann equation that makes use of a BGK collision operator. As a result, it is not surprising that numerical instability of lattice Boltzmann methods have been frequently encountered by researchers. We present an analysis of the stability of perturbations of the particle populations linearized about equilibrium values corresponding to a constant-density uniform mean flow. The linear stability depends on the following parameters: the distribution of the mass at a site between the different discrete speeds, the BGK relaxation time, the mean velocity, and the wavenumber of the perturbations. This parameter space is too large to compute the complete stability characteristics. We report some stability results for a subset of the parameter space for a 7-velocity hexagonal lattice, a 9-velocity square lattice, and a 15-velocity cubic lattice. Results common to all three lattices are (1) the BGK relaxation time must be greater than 1/2 corresponding to positive shear viscosity, (2) there exists a maximum stable mean velocity for fixed values of the other parameters, and (3) as tau is increased from the maximum stable velocity increases monotonically until some fixed velocity is reached which does not change for larger tau.

Nuber, H. Siebert, K. Weidenheimer and J. Weiss, Acta Crystal., B35, 1020 (1979). Interestingly, this isomer also crystallizes in the space group P2(1)2(1)2(1) (z = 4), but the volume it occupies is only 782.09 Angstrom(3), whereas the mer-isomer occupies a volume of 816.09 Angstrom(3). Therefore, there is a difference of 34.81 Angstrom(3)/4 molecules or a volume difference per molecule, of 8.70 Angstrom(3). If all other factors are equal, this would argue that crystals of the fac isomer are thermodynamically more stable since its higher density must be a reflection of its Madelung energy.

Previous analytical work has determined the apparent admittance for the limit a/b --> 1. These two results bracket and demonstrate the validity of earlier numerical work which determined the apparent admittance for 0 < a/b < 1. The determination of the apparent admittance for a/b --> 0 requires the asymptotic solution of an integral equation. In the derivation of the asymptotic solution to the original integral equation, a new and very curious integral equation results. This new integral equation is examined analytically and finally is solved numerically. RP SANDIA NATL LABS, DEPT 2753, ALBUQUERQUE, NM 87185 USA.

The corner constant for transverse current is now defined to correct the power dissipation of the simple impedance solution at the corner. Previous results are used to calculate its value for the case of an internal right angle in this paper. For arbitrary internal angles an integral representation is found for the transverse corner constant; it is used to obtain the transverse corner constant in the case of an external right angle. Furthermore, it is also briefly shown how the corner corrections for both axial and transverse current apply to the calculation of the propagation constant in a waveguide.

Thin films were formed using 100 keV implantations with varying ion doses and target temperatures. X-ray diffraction with a position-sensitive detector and cross-sectional transmission electron microscopy revealed that the as-implanted surfaces contained similar to 0.1 mu m thick buried amorphous layers. Rutherford backscattering spectroscopy showed that the peak concentration of nitrogen saturated up to approximately 54 at.% with increasing doses, suggesting formation of a new phase. Key words: Carbon-silicon nitride, ion-implantation. C1 OAK RIDGE NATL LAB, DIV SOLID STATE, OAK RIDGE, TN 37831 USA. RP GEORGIA INST TECHNOL, SCH MAT SCI & ENGN, ATLANTA, GA 30332 USA.

Energies of implantation were chosen using TRIM 89 to overlay the depth distributions of the sequentially implanted ions. The implanted layers were characterized using Rutherford backscattering spectroscopy, transmission electron microscopy, and optical spectroscopy. Nanometer dimension metal multicomponent colloids were formed. The depth distribution, particle size, and optical response of the composites were found to depend strongly on the ion species implanted and the relative ratio of the ion species. The optical responses are correlated with composition of the multicomponent nanoclusters. C1 OAK RIDGE NATL LAB,DIV SOLID STATE PHYS,SURFACE MODIFICAT & CHARACTERIZAT FACIL,OAK RIDGE,TN 37831.

The films were mainly (001) textured normal to the substrate surface with a high degree of in-plane orientation with respect to the substrate's major axes. These films were characterized using x-ray diffraction, Rutherford backscattering, four-point probe resistivity measurement, and transmission electron microscopy. The room temperature resistivity for LSCO and SRO films on Pt/MgO was found to be similar to 35 and similar to 40 mu Omega-cm, respectively. An ion beam minimum channeling yield of similar to 43% and similar to 33% was obtained for LSCO and SRO films, respectively. The interface between Pt and oxide was found to be smooth and free from any interfacial diffusion. This result showed that high-quality low resistivity oxide thin films can be deposited on Pt.

The C and Si co-implantations were used as an attempt to improve Al acceptor activation in SiC. The implanted material was annealed at 1500, 1600, and 1650 degrees C for 45 min. The Al implants are thermally stable at all annealing temperatures and Rutherford backscattering via channeling spectra indicated good lattice quality in the annealed Al-implanted material. A net hole concentration of 8 x 10(18) cm(-3) was measured at room temperature in the layers implanted with Al and annealed at 1600 degrees C. The C or Si co-implantations did not yield improvement in Al acceptor activation. The co-implants resulted in a relatively poor crystal quality due to more lattice damage compared to Al implantation alone. The out-diffusion of Al at the surface is more for 5Si co-implantation compared to Al implant alone, where 5Si means a Si/Al dose ratio of 5. C1 OAK RIDGE NATL LAB,OAK RIDGE,TN 37831.

Demonstrated and potential applications include film deposition, glazing and joining, alloying and mixing, cleaning and polishing, corrosion improvement, polymer surface treatments, and nanophase powder synthesis. Initial experiments at Los Alamos have emphasized thin-film formation by depositing beam ablated target material on substrates. We have deposited films with complex stoichiometry such as YBaxCuxO7-x and formed diamondlike-carbon films. Instantaneous deposition rates of 1 mm/s have been achieved because ofthe short ion range (typically 1 mu m), excellent target coupling, and the inherently high energy of these beams. Currently the beams are produced in single shot uncomplicated diodes with good electrical efficiency. High-voltage modulator technology and diodes capable of repetitive firing, needed for commercial application, are being developed. C1 SANDIA NATL LABS,ALBUQUERQUE,NM 87185.
