TI ANOMALOUS DISPERSION AND THERMAL EXPANSION IN LIGHTLY-DOPED KTa1-xNbxO3 SO FERROELECTRICS LA English DT Article AB The temperature dependences of the lattice constant and TA phonon dispersion in dilute single crystals of KTa1-xNbxO3 with 0.012 <= x <= 0.09 have been studied using x-ray diffraction and neutron scattering techniques, respectively. For x <= 0.06 an anomalous low-temperature expansion of the cubic lattice parameter is observed at a temperature T-min that increases monotonically with Nb concentration, with no measurable change in symmetry down to 10 K. Concurrent with T-min is a homogeneous broadening of the x-ray Bragg peaks which persists down to 10 K, as well as a strong relief of extinction seen by neutron diffraction. Inelastic neutron scattering measurements reveal that the coupling between TA and TO modes, first, observed in pure KTaO3, is both wavevector and concentration dependent. The q-dependence of the TO-TA mode coupling exhibits a peak at small 9 which appears to shift to higher q with increasing x. In addition, a characteristic temperature T-o is observed above and below which both TA and TO branches harden, and which coincides with T-min. In no crystal was the TO zone center mode observed to condense fully. Instead, the minimum energy attained by the q = 0 TO mode at T-o for x = 0.09 is significantly higher than that measured for either x = 0.00 or 0.012. C1 [Gehring, P. M.; Chou, Henry; Shapiro, S.

Variational bounds generated from Faddeev solutions for several contemporary, realistic potential models are presented as a function of the number of partial waves retained in the potential expansion. We demonstrate that the Faddeev wave function yields an optimal variational bound for the partial-wave truncated potential from which it is generated, but it does not yield optimal bounds for the full Hamiltonian or when the potential is partial-wave truncated at a different level. Finally, qualitative differences between H-3 solutions for static models such as the AV14 and RSC potentials and for momentum-dependent models such as the Nijmegen soft-core and Paris potentials are explored, and comparison is made with solutions for the RSC/TM two-body-force plus three-body-force model.

Released iron was distinguished from protein radicals and ferryl heme by analyzing TOLH oxidation in the presence of different chelating agents. Metmyoglobin (metMb) treatment with one mole of H2O2 per mole of heme produced protein-bound oxidants that oxidized about two molecules of TOLH per heme. Some of the oxidizing species responsible for TOLH oxidation were highly persistent (t1/2 for the decay was 3 hrs at 25-degrees-C). Iron release, metMb bleaching and the catalysis of Fenton-type chemistry were compared in metMb solutions treated with tert-butyl hydroperoxide (tBH). Iron release required about five-fold higher hydroperoxide concentrations than did metMb bleaching. Alkoxyl and methyl radical production was catalyzed by iron released from metMb but not by protein-bound iron in oxidized metMb solutions treated with tBH and ascorbic acid. The results suggest that ascorbate-mediated hydroxyl and alkoxyl radical production by hydroperoxide-treated metMb is due to released iron and that the protein-bound non-heme iron that arises during bleaching is at most a weak Fenton reagent.

The experiment consisted of determining the ratio of Mn-56 activities induced in a large manganese bath by a central 14-Me V neutron source, with and without a beryllium sample surrounding the source. The superior isotropy and flat energy response of the manganese bath gives this detector an advantage over the inhomogeneous and anisotropic detector arrays used in previous experiments for measurements of this type. Values of the multiplication have been obtained for beryllium samples of four thicknesses. The measurements are affected by several systematic effects characteristic of the manganese bath. The values of these systematic corrections are established by a combination of calculation and experimental parameterization. Detailed calculations of the multiplication and all the systematic effects are made by using a highly detailed three-dimensional Monte Carlo geometry model with the MCNP Monte Carlo program. The Young-Stewart and the ENDF/B-VI evaluations for beryllium are used in the analysis. Both data sets produce multiplication values that are in excellent agreement with the manganese bath measurements for both raw and corrected values of the multiplication. It is concluded that there is no real discrepancy between experimental and calculated values for the multiplication of neutrons in bulk beryllium. C1 LOS ALAMOS NATL LAB,LOS ALAMOS,NM 87545.

With the improved model, Mercier stability is obtained for parabolic pressure profiles at peak beta values of up to 3% for the standard configuration, which now has an average minor radius aBAR = 23.3 cm. For a configuration with a smaller plasma radius, aBAR = 15.2 cm, the maximum peak beta, 5.0%, is limited by equilibrium. The addition of a toroidal field reduces the rotational transform to <0.5. This configuration has access to the second stability regime for Mercier modes when narrow pressure profiles are used at low beta. C1 KHARKOV PHYS & TECHNOL INST,KHARKOV 310108,UKRAINE.

Values of the overall partitioning constant K were calculated from the observed compositions of the two phases using published activity coefficients for HCl(aq) in the liquid phase, assuming that the neutral HCl molecule is the only solute species present in the vapor phase, and assigning a unit fugacity coefficient for vapor-phase HCl. Partitioning is a strong function of temperature, with K increasing more than six orders of magnitude over the temperature range of this work. Measured values of K, including results available in the literature to 110-degrees-C, are well represented by a simple function of temperature T in Kelvin and solvent density rho in g . cm-3: log K = -13.4944 - 934.466/T - 11.0029 log rho + 5.4847 log T. The present measurements give directly the composition of the vapor phase over HCl(aq); partitioning of HCl to the vapor phase over NaCl(aq) brines has been estimated through the use of approximate activity coefficients for HCl(aq) in the mixed brines.

Reducing the CO2 concentration tenfold produced little, if any, effect on dissolution rate at alkaline pH (pH 8 through pH 12) at 25 and 70-degrees-C. Linear dissolution kinetics (i.e., time-invariant rates) were eventually observed in all runs. The overall trend with increasing pH is decreasing diopside dissolution rate based on the release rate of all constituents. We fit these rates by regression to a general rate law of the form r = Ak[a(H+)]n, where A is the surface area, k is the rate constant, and n is the order with respect to hydrogen ion activity. At 70-DEGREES-C over the range pH 2 through pH 10 in solutions equilibrated with atmospheric CO2, the rate of diopside dissolution based on Si release is rate (mol/cm2-S) = 2.45 (+/-0.96) X 10(-13) a(H+)0.18+/-0.03. AT 50-degrees-C the rate based on Si release is rate (mol/cm2-s) = 1.10(+/-0.61) X 10(-13) a(H+)0.21+/-0.04. At 25-degrees-C the rate based on Si release is rate (mol/cm2-s) = 2.88(+/-1.33) X 10(-14) a(H+)0.18+/-0.03. Based on a regression of the rate constants, over the temperature interval 25 to 70-degrees-C, the activation energy for the dissolution of diopside is 9.7 +/- 0.4 kcal/mol. This energy is indicative of a surface-reaction controlled dissolution process, as is the observation of crystallographically controlled etch pits.

With these partition coefficients, it should be possible to better understand the Pd-107-Ag-107 and Tl-205-Pb-205 systems of iron meteorites. In general, our schreibersite/metal and troilite/metal partition coefficients for ''compatible'' elements are quite similar to those inferred from natural assemblages. In contrast, these same partition coefficients for ''incompatible'' elements often do not even qualitatively agree with analyses of iron meteorites. We suggest that analyses of incompatible elements in iron meteorites may sometimes be dominated by minor/trace phases. Identification of such phases may allow refinement of the initial isotopic composition of Pb in the early solar system. If our trace impurity model is correct, it may also be possible to reconcile iron meteorite cooling rates inferred from silver isotopic systematics with those deduced from metallography.

Reference materials had previously been studied by optical absorption spectroscopy and included Cr-bearing borosilicate glasses synthesized under controlled oxygen fugacity and Cr-doped olivines. The energy dependence of XANES spectral features defined by these reference materials indicated that Cr is predominantly divalent in the lunar olivine and trivalent in the pyroxene. These results coupled with the apparent f(O2)-independence of partitioning coefficients for Cr into olivine imply that the source magma was dominated by divalent Cr at the time of olivine crystallization.

Steps do not interact at separations of approximately 10 nm and above, indicating that surface diffusion does not control calcite growth. Instead, steps advance by material addition from solution onto step sites or a narrow adjacent zone. Step nucleation is primarily at growth spirals, and no spontaneous surface nucleation is observed; growth rate is controlled by spiral rotation rate. Thus, classical growth models based on rapid surface diffusion are inapplicable to calcite and possibly to many other minerals. C1 UNIV CALIF SANTA BARBARA,DEPT PHYS,SANTA BARBARA,CA 93106.

We analyze the three-dimensional structure of convection driven by basal heating at Rayleigh number Ra = 6.67 x 10(6) and Ekman number E = 10(-4) in a shell with the geometry of the Earth's liquid outer core. Calculations using two different body force distributions are compared: radial gravity and centrifugal acceleration. In both cases the flow consists of a chaotic array of small-scale, time-dependent columnar vortices aligned parallel to the rotation axis plus large-scale zonal and meridional circulations. The columnar vortices are driven by thermal plumes localized in the equatorial region. The zonal flow consists mainly of two parts: a cylindrical (geostrophic) part driven by Reynolds stresses derived from the small-scale convection and a thermal wind driven by large-scale temperature gradients. For both body force distributions, convective heat transfer occurs mostly in the equatorial region. The overall structure of the convection, and the resulting zonal flow and longitudinally-averaged helicity are remarkably similar for the two body force distributions outside of the inner core tangent cylinder. In that region of the spherical shell, the component of gravity perpendicular to the rotation axis is the dynamically important component for convection at these Rayleigh and Ekman numbers.

The investigated phenomena include the sequence of transitions to chaos and the differential mean zonal rotation. At the fixed Taylor number Ta = 10(6) and Prandtl number Pr = 1 and with increasing Rayleigh number R, convection undergoes a series of bifurcations from onset of steadily propagating motions SP at R = R(c) = 13050, to a periodic state P, and thence to a quasi-periodic state QP and a non-periodic or chaotic state NP. Examples of SP, P, QP, and NP solutions are obtained at R = 1.3R(c), R = 1.7R(c), R = 2R(c), and R = 5R(c), respectively. In the SP state, convection rolls propagate at a constant longitudinal phase velocity that is slower than that obtained from the linear calculation at the onset of instability. The P state, characterized by a single frequency and its harmonics, has a two-layer cellular structure in radius. Convection rolls near the upper and lower surfaces of the spherical shell both propagate in a prograde sense with respect to the rotation of the reference frame. The outer convection rolls propagate faster than those near the inner shell. The physical mechanism responsible for the time-periodic oscillations is the differential shear of the convection cells due to the mean zonal flow. Meridional transport of zonal momentum by the convection cells in turn supports the mean zonal differential rotation. In the QP state, the longitudinal wave number m of the convection pattern oscillates among m = 3,4,5, and 6; the convection pattern near the outer shell has larger m than that near the inner shell. Radial motions are very weak in the polar regions. The convection pattern also shifts in m for the NP state at R = 5R(c), whose power spectrum is characterized by broadened peaks and broadband background noise. The convection pattern near the outer shell propagates prograde, while the pattern near the inner shell propagates retrograde with respect to the basic rotation. Convection cells exist in polar regions. There is a large variation in the vigor of individual convection cells. An example of a more vigorously convecting chaotic state is obtained at R = 50R(c). At this Rayleigh number some of the convection rolls have axes perpendicular to the axis of the basic rotation, indicating a partial relaxation of the rotational constraint. There are strong convective motions in the polar regions. The longitudinally averaged mean zonal flow has an equatorial superrotation and a high latitude subrotation for all cases except R = 50R(c); at this highest Rayleigh number, the mean zonal flow pattern is completely reversed, opposite to the solar differential rotation pattern.

EIA amalgamated the energy-related activities of over 50 separate agencies, when it was chartered in DOE in 1977, ''to collect, evaluate, assemble, and analyze energy information....'' Six tensions have characterized the agency during its history: data quality, the role of modeling, confidentiality of data, resources and requirements, the independence of EIA, and timeliness vs. accuracy.

Currently, EIA's database is derived from the demonstrated reserve base (DRB) of coal, a compilation of data from published sources, unified by adherence to standardized physical criteria of minability, but never intended for the detailed coal supply and policy analyses demanded today. The CRDB Program is designed to engage the expertise available at State geological surveys in compiling best current State-level estimates of both quantities and quality of available coal reserves through cooperative agreements with EIA. The CRDB emphasizes integration of more data on coal quality, use of data from unpublished sources, cooperation with industry and other government sources, and flexibility of criteria to take into account local accessibility and mining conditions and utilize computerized geographic information systems or coal resource software. The results of pilot projects in Ohio and Wyoming are summarized. Areas nominated for support in the program include 15 additional priority coal regions in 14 States, which comprise 95 percent of the current reserve estimates and most of the coal-bearing areas of low sulfur potential.

The quality assurance group assures that these efforts are effective through a systematic process of data and model evaluation, applied research to address technical problems, and administrative procedures and standards to promote improved practice. Together the program offices and the quality assurance group keep the agency's leadership fully apprised of quality concerns and actively involved in solving quality problems.

Although other ground-water remediation technologies are currently being examined and show intriguing promise, pump and treat remains the only dependable technology for cleanup of deep (i.e., > 50 ft below ground surface) widespread ground-water condition. The perceived shortcomings of pump and treat result from (1) the tendency of most contaminants to sorb to formatiom materials, thus retarding contaminant removal; (2) geologic complexity, which requires detailed characterization for the design of optimal extraction systems within available resources; and (3) the failure to apply dynamic well field management techniques. The alternative, ''smart pump and treat,'' consists of (1) detailed characterization of the geology, hydrology, and chemistry; (2) use of computer-aided data interpretation, data display, and decision support systems; (3) removal of source terms, if possible; (4) initial design for plume containment and source remediation; (5) phased installation of the well field; (6) detailed monitoring of the remediation; (7) active ongoing reevaluation of the operating well field, including redesign as appropriate (dynamic management); (8) reinjection of treated ground water to speed the flushing of contaminants; and (9) setting of appropriate cleanup levels.

This inconsistency leads to erroneous estimates of inhalation exposures and can distort the relative importance of inhalation and ingestion-based exposures to environmental contaminants that are present in foods, air, and water. As a means of dealing with this problem, a new methodology for estimating breathing rates is presented that is based on the oxygen uptake associated with energy expenditures and a ventilatory equivalent that relates minute volume to oxygen uptake. Three alternative energy-based approaches for estimating daily inhalation rates are examined: (1) average daily intakes of food energy from dietary surveys, adjusted for under reporting of foods; (2) average daily energy expenditure calculated from ratios of total daily expenditure to basal metabolism; and (3) daily energy expenditures determined from a time-activity survey. Under the first two approaches, inhalation rates for adult females in different age cohorts ranged from 9.7 to 11 m3 d-1, whereas for adult males the range was 13 to 17 m3 d-1. Inhalation rates for adults determined from activity patterns were higher (i.e., 13 to 18 m3 d-1), however, those rates were shown to be quite sensitive to the energy expenditures used to represent light and sedentary activities. In contrast to the above estimates, the ICRP 23 reference values for adult females and males are 21 and 23 M3 d-1 (Snyder et al. 1975). Finally, the paper provides a technique for determining the short-term breathing rates of individuals based on their basal metabolic rate and level of physical activity.

The instruments studied are the Xetex 303B Pacer, the Bicron Micro Rem survey meter, the Victoreen 450p survey meter, the Victoreen 440 survey meter, the SLAC orange meter, the Keithley 36150 survey meter, the Anderson-Braun neutron remmeter, and the Victoreen 488 neutron survey meter. The results show that the effect may depend on several factors such as instrument design, alignment of the instrument axis with the magnetic flux lines, whether the instrument is stationary or moving relative to the magnetic field, the direction of the movement relative to the magnetic flux lines, and the magnetic field intensity. Also presented are results of work to enhance magnetic shielding of some of the instruments. RP LIU, JC (reprint author), STANFORD UNIV, STANFORD LINEAR ACCELERATOR CTR, STANFORD, CA 94309 USA.

Modern methods for atomic capture of the negative muon are reviewed. Elastic and inelastic cross sections obtained in the improved adiabatic representation are given, and rates at liquid-hydrogen density are tabulated for easy reference and comparison.

For ddmu and dtmu formation, however, the resonance mechanism of Vesman is dominant and produces some dramatic effects. For ddmu, the temperature dependences for the different hyperfine states provide a striking confirmation of the theory. For dtmu, the comparison with experimental is much more difficult, and furthermore the appearance of an evident three-body contribution to the formation cross section presents a formidable challenge to theory. A completely convincing and practical method of calculating this term has yet to be achieved, but a classical trajectory model which provides some insight into the underlying physics is presented.

We give complex eigenvalues and alpha-mu sticking fractions for the (L, upsilon) = (0, 0) and (0, 1) states of dtmu using variational Hamiltonian matrix elements that have been properly symmetrized by means of the Block operator. Expressions for the fusion rate and alpha-mu sticking fraction are developed from a time-dependent theory that uses the complex-energy states corresponding to the poles of the system S-matrix. These are shown to reduce with the appropriate approximations to the expressions and values commonly used. Additional nuclear effects on these quantities can easily be studied within the framework developed, but they are not expected to be large.

The results of these dedicated experiments provide rich information about muon-induced few-body reactions and contribute significantly to a better overall understanding of muCF. A summary of the recent progress will be presented. Special emphasis will be put on two characteristic examples, namely a new experimental approach to study the muonic cascade in H-D mixtures and the systematic study of hyperfine effects in muon-induced reactions.

Many attempts were made to determine by calculations and measurements the probability for initial sticking omega(s)0 (immediately after dtmu fusion) and for final sticking omega(s) (after the ag came to rest). Previous results based on neutron disappearance rates and on the observation of alphamu-X-rays were controversial and also in some disagreement with theory. New data are reported from PSI on direct observation of final sticking, using a setup with the St. Petersburg ionization chamber. These data mark a significant improvement in reliability and may clarify questions concerning previous discrepancies. The new result is omega(s) approximately (0.56 +/- 0.04)%, lower than the theory prediction omega(s) = (0.65 +/- 0.03)%, at medium density. C1 PETERSBURG NUCL PHYS INST,GATCHINA 188350,RUSSIA.

This experiment was based on an ''active-target'' ionization chamber (IC) built at Gatchina, Russia, and an array of plastic neutron counters. In three runs approximately 5 x 10(6) isolated alpha signals were recorded with around one half of these occurring in the inner chamber region where we have more complete understanding of the systematic errors. Particularly from a long run in 1992 we were able to obtain a very clean sticking peak of some 5000 mualpha events. However, to reach an accurate value of sticking, all systematic effects and several major backgrounds had to be understood in detail. To this end a Monte Carlo code was written to simulate the full electrostatic environment of the IC and to recreate completely each signal type including the actual tritium decay noise from the live experiment. A slightly model dependent value of approx. 0.56 +/- 0.04% is obtained for final sticking. C1 PAUL SCHERRER INST,VILLIGEN,SWITZERLAND. INST MEDIUM ENERGY PHYS,VIENNA,AUSTRIA.

An antiproton which passes through the Coulomb field of a nucleus will create e+e- pairs, and antihydrogen will form when a positron is created in a bound instead of continuum state about the antiproton. The cross section for this process is roughly 3 Z2 pb for antiproton momenta about 6 GeV/c. A sample of 600 antihydrogen atoms in a low-emittance, neutral beam will be made in 1995 as an accidental byproduct of Fermilab experiment E760. We describe a simple experiment, Fermilab Proposal P862, which can detect this beam, and outline how a sample of a few-10(4) atoms can be used to measure the antihydrogen Lamb shift to 1 %.

For an antiproton slowing in hydrogen, this backward scattering would result in the loss of nearly all of its energy in a single collision, since it and a hydrogen atom have nearly the same mass. Such energy loss would have a significant effect on the energy distribution of antiprotons at energies where capture by the protons of hydrogen is possible and might, thereby, affect the capture rate and the distribution of capture states. In the semiclassical treatment of the problem with an adiabatic potential energy, brickwall scattering is indeed present, and with a substantial cross section. However, this model appears to underestimate inelastic processes. Based on calculations for negative muons on hydrogen atoms, these processes appear to occur for about the same impact parameters as brickwall scattering and thus substantially reduce its effect.

Analytical methods are also being developed to analyze the information this lidar can take. The lidar is able to measure the absolute water content and then calculate evaporative fluxes and other atmospheric parameters quickly over relatively large areas. This capability provides new opportunities for the study of microscale atmospheric processes. Examples of data and analyses are presented. An analysis is presented which determines the spatial and temporal resolution which is required of a remote sensor in the boundary layer. C1 UNIV CALIF DAVIS,DEPT LAWR,DAVIS,CA 95616.

TI An efficient method for transposing large matrices and its application to separable processing of two-dimensional signals SO IEEE TRANSACTIONS ON IMAGE PROCESSING LA English DT Article AB Our goal is to transpose an arbitrary matrix when the total number of matrix elements is too large to store them all in random-access memory. This problem is often a computational bottleneck in large computed-imaging problems. We derive a simple algorithm for obtaining the transposed matrix using only two read/write passes over the data. This algorithm is efficient for a wide range of practical problems. We observe that the first step of the algorithm reorders the data in a form that permits efficient access to the data either by row or by column. Thus if the only reason for constructing the transpose is to provide efficient access to the data for processing along the "slow" dimension of a two-dimensional data set, the matrix transpose can be eliminated simply by storing the data in this intermediate form. Furthermore, this reordering can be performed in place with a single read/write pass over the data. C1 Univ Calif Lawrence Livermore Natl Lab, Livermore, CA 94550 USA.

Raman spectroscopy is nondestructive and relatively rapid and is well suited for the characterization of carbon films. Specific features in the Raman spectra are empirically correlated with the rates of specific types of mechanical wear for both hydrogenated and unhydrogenated films. This observation is interpreted in terms of a random covalent network, in which the mechanical performance of the film is determined by the nature of the bonding that links sp2-bonded domains.

The preference for the c-axis to lie parallel to the groove direction has been quantified. A small in-plane stress was measured which displayed an anisotropy between the two directions. The magnitude of this stress appears to be large enough (according to a simple calculation) to contribute to observed coercive anisotropies. The techniques used for extracting the in-plane crystallographic texture and the value of the in-plane stress from the x-ray measurements are discussed.

Even then, magnetic diffusion (the ''normal'' skin effect) will limit acceleration. In this paper, the performance limits for railguns which are free from the velocity-skin effect are investigated by deriving the upper limits for a specific kind of power supply. Previous performance estimates made for solid-armature railguns are examined in the light of these results and are found to be relatively very optimistic.

Testing this idea with data from several guns we find confirmation, provided the required flux velocity increases with the square of the linear current density. This leads to the conclusion that these guns have a momentum limit while they are operating as true electromagnetic launchers. That limit is derived. High-performance railguns reach this limit during current rise, and most of their momentum comes from a hybrid phase. The hybrid phase has a pressure limitation at high velocity similar to electrothermal, light-gas, and powder guns. The 6 km/s ''velocity limit'' is explained by this pressure limitation.

Forty stages of this design (Phase 1 coilgun) will provide a testbed for coil designs and system components while accelerating 200 to 400 gram projectiles to 1 km/s. We have successfully qualified the Phase 1 gun by operating 40 stages at half energy (10 kJ stored/stage) accelerating 340 gram, room-temperature, aluminum-armature projectiles to 406 m/s. We expect to accelerate 200 gram projectiles cooled to -196-degrees-C to three times this velocity when operating at full energy.

For the earth-to-orbit (ETO) application, the baseline conceptual design consists of a 960-m long gun sited in a tunnel at 25-degrees inclination. The gun launches an 1820-kg package that includes a 100-kg satellite and a 650-kg boost rocket for orbital insertion. For the lunar application, the launcher is 200 m long. A 100-kg load of LLOX is packaged in a 10-kg fiber-wrapped tank, accelerated at 2 kgees in an aluminum bucket (armature), and launched at 2.33 km/s at 30-minute intervals. The canisters arrive at L2 2.97 days later and are captured by robotic tugs that deliver them to a fuel depot. The total mass of LLOX delivered per year is 867 Mg (metric tons).

Our understanding of the three-dimensional plasma armature flowfield has been developed through a combination of highly instrumented railgun experiments, secondary arc performance models and two-dimensional MHD calculations. These two-dimensional calculations are only qualitative in nature, but they provide insight into the complex armature flow and indicate that the formation of secondary armatures, ablation drag and primary armature separation are interrelated. Experimental evidence suggests that three-dimensional MHD flow effects are very important in controlling these phenomena. A complete understanding of these complex armature effects will require the development of detailed three-dimensional MHD codes validated by highly instrumented and diagnosed railgun experiments.

Although hybrid armatures are often used, their design has been empirical and their performance sporadic. As a first step towards understanding hybrid design and performance, we have begun a combined numerical simulation and experimental verification effort. This paper will describe numerical simulations performed with a quasi 1-D MHD code (CONFUSE) which has been applied to simulate the behavior of plasma brushes used in hybrid armatures. The simulations have provided estimates of the plasma brush length, resistive voltage drop and temperatures corresponding to a range of; 1) brush gap size, 2) fuse thickness, and 3) magnetic pressure. The results or these simulations is presented and discussed. RP HAWKE, RS (reprint author), LAWRENCE LIVERMORE NATL LAB,POB 808,LIVERMORE,CA 94550, USA.

In these tests we accelerated projectiles to 4 km/s without incurring thermal ablation of the bore materials. Comparison of shots below and above the ablation threshold showed a marked difference tn armature structure and behavior. Non-ablating armatures showed no signs of conventional secondary or restrike arcs. Furthermore, a double peaked structure that formed early in many of the non-ablating shots showed a tendency to merge or heal, suggesting an inherent stability in the armature. Our measurements show that augmentation provides the expected increase in force, M'I(R)I(A), without increasing the power dissipation in the armature. Further, our test results are consistent with the reported theoretical value of 12 MWs1/2/m2 for the ablation threshold of Al2O3. C1 LOS ALAMOS NATL LAB,LOS ALAMOS,NM 87544.

An investigation was undertaken to examine the kinetic course of the pulmonary injurious response to PFIB when inhaled by adult Fischer 344 rats for 10-min durations at mass concentrations ranging from 50 to 200 mg/m3. No lung gravimetric increases or histopathological changes were observed after exposure to 50 or 83 mg/m3 concentrations of PFIB. At greater-than-or-equal-to 90 mg/m3, overt lung injury that was detectable by lung gravimetric and histopathological changes was observed within hours after the exposures, with the postexposure times or ''latency periods'' prior to onset of these responses being inversely related to exposure mass concentration. Latency periods occurring after exposure to 100, and 110 mg/m3 were approximately 8 and 4 hr, respectively. No latency period was observed following the exposure of rats to 200 mg/m3. The ultimate severity of the pulmonary injurious response to PFIB increased with increasing exposure mass concentration. In a second component of the study, lungs of rats exposed to 100 or 200 mg PFIB/m3 were examined by transmission electron microscopy at various times after the exposures to obtain ultrastructural information about the postexposure course of alveolar injury at the cellular level, while also examining for cellular and architectural injury that may occur during a post-PFIB exposure ''latency period,'' as defined by lung gravimetric and conventional histopathological criteria. As of 1 hr after exposure to these concentrations of PFIB, alveolar epithelial cells and endothelial cells showed abnormal vacuolization and blebbing. These changes progressed over time, resulting in the denudement of the alveolar surface, endothelial cell swelling and the formation of fenestrations in the endothelial cell barrier, perivascular and interstitial edema, and the flooding of the alveoli with vascular constituents, including extravasated erythrocytes. Only the lung's alveolar macrophages and interstitial fibroblasts appeared to be relatively insensitive to the damaging effects of PFIB. While the severity and rate of development of these changes was greater with the higher 200 mg/m3 concentration of PFIB, such damage, while less extensive at comparable postexposure times, was also present during the latency period after exposure to 100 mg/m3. Thus, significant lung injury can occur shortly after exposure to PFIB that is not detectable by more conventional lung gravimetric and histopathological criteria.

It is shown that Cr is an efficient solid solution strengthener in NiAl, effectively tripling the 0.2% yield strength at the 1 at. % level; this is also its maximum solubility. The presence of Cr also increases the BDTT of NiAl by approximately 150K and reduces the already limited ductility to essentially zero. Larger alloying additions produce fine alpha-Cr precipitation. However, the associated hardening contribution due to precipitation is relatively minor compared with solid solution effects. Independently of Cr content, stoichiometric deviation was observed to produce significant increases in strength and BDTT. It is shown that hardening due to both intrinsic and extrinsic substitutional defects is ultimately a function of the solubility, site preference, and alloying strategy (e.g., a particular Ni/Al ratio, or Cr substituted solely for either Ni or Al) of the Cr addition.

The most remarkable feature found in the calculated binding charge density is the polarization of the p-electron at the aluminum sites, which gives rise to a large bond bending force between the Ti and Al layers. For the point defects, the absence of structural vacancies is predicted in TiAl, and the deviations from stoichiometry are accommodated by the substitutional antisite defects on both sublattices. High vacancy formation energies are obtained, which are closely related to the strong Ti-Al bonding and the similar atomic radii of Ti and Al.

The hardness values for specimens heat-treated at 500-degrees-C and water-quenched to ambient temperature increase slowly with composition until at about 48 at.% Al. At higher Al concentrations the hardness values increase more rapidly. For specimens heat-treated at temperatures higher than 700-degrees-C and water quenched to ambient temperature, the hardness values increase with Al concentration with little change in slope through the entire composition range of 40-51 at.% Al. The compositional dependences of the hardness values are similar to those of the vacancy concentrations in FeAl. The vacancy concentrations as a function of Al composition were obtained from a thermodynamic model and experimental data at the stoichiometric composition. The close resemblance of the shapes of the hardness curve and the vacancy concentration curve suggests that the hardness and thus the yield strength may be related to the presence of vacancies in the lattice. This conclusion is further supported by the evidence that the hardness of FeAl increases with the square root of the vacancy concentration. This type of relationship agrees well with established point-defect strengthening models, based on the interaction of a moving dislocation with a point defect.

SLIP SYSTEMS SO INTERMETALLICS LA English DT Article DE INTERMETALLICS; NIAL; DISLOCATIONS; CHROMIUM ID SINGLE-CRYSTALS; DISLOCATIONS; ALUMINIDES; BEHAVIOR AB One of the principal obstacles to room temperature tensile ductility in NiAl is an insufficient number of independent slip systems, due to the sole operation of the [100]{011} system. It has been both predicted and reported that Cr additions to NiAl induce [111]{112} slip, increasing the number of independent slip systems to five, a number sufficient for general plasticity. However, no attendant increase in tensile ductility has been observed. The present study reexamines the effects of Cr on the predominant room temperature slip system in polycrystalline NiAl, as a function of Cr content, Ni/Al ratio and processing route. It is shown that Cr has essentially no effect on the slip system in NiAl at room temperature, while processing by extrusion, compared with casting and homogenization, produces a small, yet significant, proportion of [110]{110} dislocations.

For alloys with or without boron, the Kolmogorov-Johnson-Mehl-Avrami relationship holds, with the Avrami exponent near unity, and the recrystallization rate is very slow. The activation energies for recrystallization are respectively 480 and 492 kJ/mol for boron-free and boron-doped alloys compressed to 17%, and 305 kJ/mol for boron-doped alloy cold-rolled to 40%. The grain growth kinetics obey a power law with the time exponent ranging from 0.2 to 0.4. The boron effect at 500 ppm was found to be small on both recrystallization and grain growth in Ni3Al.

These algorithms accommodate multiple digestions and are applicable when the order of restriction fragments in each clone is not determined. The computer algorithm for clone pair overlap probability calculation generates the likely restriction fragment pair matchings. (As will be seen, this algorithm computes permanents.) Features of the data are characterized including experimental reproducibility. We also give details of the simulation of data for the purpose of computing clone pair overlap probabilities. Our algorithm is also applied to a simpler simulated fingerprint, consisting of a single restriction digest, to characterize the overlap detection afforded by the combination of experiment and data analysis. In addition, we discuss the applications of algorithms involving interval graphs to the positioning of clones. The pairwise overlap probabilities are refined by using the constraint that clones are derived by fragmenting a linear DNA molecule and that clones are typically subintervals. The interval graph algorithms can be applied to diverse mapping protocols. Furthermore, they address inconsistencies due to repeated DNA sequences or cloning artifacts. Finally, we describe an incremental technique for contig assembly. C1 LOS ALAMOS NATL LAB,DIV THEORET,LOS ALAMOS,NM 87545. IBM NEW MEXICO,LOS ALAMOS,NM 87545.

Particular attention is devoted to the complex refractive indices for char and ash. A dispersion relation is developed from sparse extinction data that can be used to estimate the optical constants of char. Considerable uncertainity and scatter are found in the literature data on ash optical constants and are attributed to variability in ash composition, lack of experimental rigor and limitations in the data reduction procedures. A correlation is presented for estimating the complex refractive indices of ash as a function of its mineral composition. A parametric study is conducted to elucidate the role of char, soot and ash particulates in determining the radiation properties of coal flames. The effects of combustion particulates are discussed in terms of the modification of the band structure of gas radiation to a luminous spectrum. introduction of scattering in radiation transport, particle size distribution. particle loading and particle composition. The results are interpreted as possible effects of coal beneficiation, micronization and flyash composition on heat transfer to the water walls of a coal furnace.

The aluminum channel is heated on one side; the other side of the channel is a Pyrex window allowing visual observation of the CHF event. Both upward and downward flow conditions are tested with exit pressure varying from 20 to 85 kPa, inlet water temperature varying from 295 to 343 K (inlet subcooling = 5-72 K), and mass flux varying from 30 to 80 kg s-1 m-2. Measured test results indicate downward flow dryout CHF occurring at 85% of upward flow dryout CHF values. This percentage is believed to result from the flow instability and reduced inlet subcooling induced by the counter-current flow. New dryout CHF correlations for low flow rates, representative of natural convection boiling, are recommended for both upward and downward flow.

The first objective is to quantify the three dimensional characteristics of hypervelocity impact events, and the second is to provide a diagnostic with the ability to capture high fidelity information for the validation of sophisticated three-dimensional hydrocodes. The holographic image-capturing subsystem uses a Q-switched, seeded, frequency-doubled Nd-YAG laser which produces 5 ns, 750 mJ, coherent pulses at 532 nm. Holographic images have been captured of the back-surface debris bubble from 4 km/s perforating impacts and crater ejecta from 2 km/s non-perforating impacts. A prototype holographic reconstruction and image analysis subsystem has been assembled that provides the ability to measure both the spatial distribution of particles and the morphology of individual particles produced in a hypervelocity impact event. The demonstrated image resolution of this system is 20 mum; however, higher resolutions are possible with magnification optics. C1 KTECH CORP INC,ALBUQUERQUE,NM 87110.

The objective of the tests was to provide the first experimental data on the advanced shielding concepts for evaluation of the analytical equations (shield performance predictors) at velocities previously unattainable in the laboratory, and for comparison to single Whipple Bumper Shields (WBS) under similar loading conditions. The results indicate that significantly more mass is required on the back sheet of the WBS to stop an approximately flat-plate particle impacting at 7 km/sec and at 10 km/sec than the analytical equations (derived from spherical particle impact data) predicted. The Multi-Shock Shield (MSS) consists of four ceramic fabric bumpers, and is lighter in terms of areal density by up to 33%, but is as effective as the heavier WBS under similar impact conditions at about 10 km/s. The Mesh Double Bumper shield (MDB) consists of an aluminum wire mesh bumper, followed by a sheet of solid aluminum and a layer of Kevlar(R) fabric. It provides a weight savings in terms of areal density of up to 35% compared to the WBS for impacts of around 10 km/s. C1 MCDONNELL DOUGLAS SPACE SYST DIV,HOUSTON,TX 77062.

RHALE is the successor to CTH, Sandia's 3-D Eulerian shock physics code, and will be capable of solving problems that CTH cannot adequately address. We discuss the new Lagrangian capabilities of RHALE, which include arbitrary mesh connectivity, superior artificial viscosity, and improved equations of state. We also discuss some of the issues we have encountered in the choice of an axisymmetric element technology and our resolution of these issues. We discuss the MMALE algorithms that have been extended for arbitrary grids in both two and three dimensions and present the results of calculations that are of interest to the hypervelocity impact community. The MMALE addition to RHALE provides the accuracy of a Lagrangian code while allowing a calculation to proceed under very large distortions. Coupling an arbitrary quadrilateral or hexahedral grid to the MMALE solution facilitates modeling of complex shapes with a minimum number of computational cells. RHALE allows regions of a problem to be modeled with Lagrangian, Eulerian or ALE meshes. In addition, regions can switch from Lagrangian to ALE to Eulerian based on user input or mesh distortion. For ALE meshes, new node locations are determined with equipotential schemes. Element quantities are advected with donor, van Leer, or Super-B algorithms. Nodal quantities are advected with the second order SHALE or HIS algorithms. Currently, material interfaces are determined with the SLIC algorithm; however, both two and three dimensional versions of Youngs' interface tracker are being investigated. To facilitate the development of such a lengthy code, we choose to write in the C++ programming language. We feel that object-oriented programming techniques are superior to conventional programming techniques. However, we discuss a few of the efficiency problems we have encountered using these techniques and how we have addressed these problems.

In addition, the high pressure loading must be uniform, structured, and shockless, i.e., time-dependent to prevent the flier plate from either fracturing or melting. In this paper, a novel technique is described which allows the use of 100 GPa megabar loading pressures and 10(9)-g acceleration to launch intact flier plates to velocities of 12.2 km/s. The technique has been used to launch nominally 1-mm thick aluminum, magnesium, and titanium alloy plates to velocities over 10 km/s, and 0.5-nun thick aluminum and titanium alloy plates to velocities of 12.2 km/s.

Upon impact by a 19 mm (0.87 mm thick, L/D approximately 0.5) flier plate, the thin aluminum bumper shield disintegrates into a debris cloud. The debris cloud front propagates axially at velocities of approximately 14 km/s and expands radially at a velocity of approximately 7 km/s. Subsequent loading by the debris on a 3.2 mm thick aluminum substructure placed 1 14 mm from the bumper penetrates the substructure completely. However, when the diameter of the flier plate is reduced to 12.7 mm, the substructure, although damaged, is not perforated. Numerical simulations performed using the multi-dimensional hydrodynamics code CTH also predict complete perforation of the substructure by the subsequent debris cloud for the larger flier plate. The numerical simulation for a 12.7 mm flier plate, however, shows a strong dependence on assumed impact geometry, i. e., a spherical projectile impact geometry does not result in perforation of the substructure by the debris cloud, while the flat plate impact geometry results in perforation.

These data include Hugoniot states, release paths and strength. Two classes of impact techniques have been employed for measuring equation-of-state properties for rocks and rock simulants These techniques both use velocity interferometer diagnostics. One, employing a sample-in-projectile geometry, provides high-precision Hugoniot data and continuous release trajectories for dry or water-saturated materials. The majority of the present experiments have been performed with this geometry. The other, employing a sample in-target geometry, provides loading path and Hugoniot data as well as limited release data. Materials studied by these two techniques have included a variety of tuffs, rhyolites, carbonates, grouts and an epoxy-alumina mixture. Uncertainties in the results from these techniques have been estimated by analyzing the effects of errors in observables and ancillary material properties.

This will change the mechanical behavior towards increased ductility when a semi-conductor is compressed until it becomes metallic; and towards increased brittleness when a transition metal is expanded so as to localize its d-band electrons.

The Fast Shock Tube, a cylindrically convergent high-explosive driver, has been used to accelerate projectiles. Detailed modeling of the experiments, including high-pressure gas flow, projectile instability, and projectile fracture, has been done with the MESA/2D code. Modeling results show quantitative agreement with the average behavior of the system. However, details of projectile behavior are not predicted well. Observed velocity distributions across the diameter of a projectile or projectile shapes are only in qualitative agreement with calculations. This, then, presents the major constraint on the successful design of a launch system: that the processes that limit projectile integrity depend on the details of the drive conditions, and these details are not quantitatively modeled at this time.

We have performed a series of high-velocity experiments specifically designed to examine the fragmentation of the projectile during impact. High-strength, well-characterized steel spheres (6.35 mm diameter) were launched with a two-stage light-gas gun to velocities in the range of 3 to 5 km/s. Normal impact with PMMA plates, thicknesses of 0.6 to 11 mm, applied impulsive loads of various amplitudes and durations to the steel sphere. The extent of fragmentation, loss in momentum, and divergence of the debris are shown to correspond to the impact conditions. Multiple flash radiography was used to monitor material motion and fragmentation of the steel sphere during the impact event. Dynamic fragmentation theories, based on energy-balance principles, were used to evaluate local material deformation and fracture state information from CTH, a three-dimensional Eulerian solid dynamics shock wave propagation code. The local fragment characterization of the material defines a weighted fragment size distribution, and the sum of these distributions provides a composite particle size distribution for the steel sphere. The calculated axial and radial velocity changes agree well with experimental data, and the calculated fragment sizes for a specific experiment are in qualitative agreement with the radiographic data.

The geometry under consideration involves placing the flyer on the end of an optical fiber through which the laser pulse is delivered. The blowoff products driving the flyer are thus fully tamped. A model, based on the Gurney theory for explosively driven plates, is derived for predicting the final velocity of these flyers. All but two of the required input parameters are readily available; those two can be extracted from one limited set of experimental measurements. Data on aluminum flyers illustrate that once the input parameters have been determined, the model predicts changes resulting from variations of laser fluence and pulse duration as well as flyer thickness and diameter. Additional data on copper and magnesium indicate that the energy-coupling efficiency can vary by at least 50%, depending on the flyer material.

The impulsive load delivered by a membrane impact will exceed the momentum/area of the membrane because of rebound, blow-off of vaporized membrane material, and ejection of molten and fractured material from the target (impulse gain). One of the objectives of the study was to quantify the impulse gain in the velocity range of interest. Also of interest was the physical damage to the target including spall, melting and fracture. Understanding these damage mechanisms is important for protecting spacecraft from the impact of space debris and meteoroids. Simple theories account for the flyer rebound, but hydrodynamic modeling is required to treat the blow-off off of target material. At lower velocities, the blow-off is negligible, but at 10 km/s calculations show it to be equal to the rebound momentum for one-dimensional (1-D) impacts. The modeling of three-dimensional (3-D) experiments revealed large effects at the edge of an impacting membrane, prompting an emphasis on 1-D pressure profile experiments.

These impact experiments use the 6 MV vertical Van de Graaff accelerator of the Ion Beam Facility at the Los Alamos National Laboratory to electrostatically accelerate highly charged iron micro-spheres. The sub-micron spheres, from a random size distribution, are shocklessly accelerated along an 8 m flight path. Ultra-sensitive charge detectors monitor the passage of the projectiles at a rate of up to 100 projectiles/second. An online computer records and displays in real time the charge, velocity and mass of the projectiles and provides cross correlation between the events observed by the several in-flight charge detectors and impact detectors. Real-time logic controls an electrostatic kicker which deflects projectiles of selected charge and velocity onto the target. Thus each experiment consists of an ensemble of 10 to 40 impacts onto a single target within a narrow window of the projectile parameter space, providing excellent statistical resolution of each data point. The target materials used include single crystal copper and single crystal aluminum, gold, and quartz as well as pyrolytic graphic and epoxy used in composite materials of interest to space applications. We also conducted impact experiments onto thin Mylar and nickel foils. This paper presents these experiments and summarizes the cratering characterization performed to date. Emphasis is placed on cratering results in several materials over a range of impact velocities. C1 SCI APPLICAT INT CORP,DIV 212,ALBUQUERQUE,NM 87106.

But the extreme smallness of the micro impact events brings into question whether the usual shock-hydrodynamic size scaling can be assumed. It is to this question of the validity of size scaling (and its refinement) that the present study is directed. Impact experiments are compared in which two comparable impact events at a given velocity, a microscopic impact and a macroscopic impact, are essentially identical except that the projectile masses and crater volumes differ by nearly 12 orders of magnitude---linear dimensions and times differing by 4 orders of magnitude. Strain rates at corresponding points in the deforming crater increase 4 orders of magnitude with the size reduction. Departures from exact scaling, by a factor of 3.7 in crater volume, are observed for copper targets--with the micro craters being smaller than scaling would predict. This is attributed to a factor 4.7 higher effective yield stress occurring in the micro cratering flow. This, in tum, is because the strain rate there is about 10(8)/sec as compared to a strain rate of only 10(4)/sec in the macro impact. The measurement of impact craters for very small impact events leads to the determination of metal yield stresses at strain rates an order of magnitude greater than have been obtained by other methods. The determination of material strengths at these exceedingly high strain rates is of obvious fundamental importance. Results are compared to recent theoretical models by Follansbee, Kochs and Rollett. Finally, the problem is addressed of predicting crater sizes in a target material with strain rate effects. First some basic results are recalled pertaining to the late stage equivalence of hypervelocity impacts. It is then seen, for a strain rate dependent material, that the curve of dimensionless crater volume versus impact velocity is replaced by a family of curves, each member of which is for one final crater size. The spacing of the curves is determined by the stress versus strain properties of the material. C1 SCI APPLICAT INT CORP,ALBUQUERQUE,NM 87106.

The study described in this.paper seeks to find some of these answers, by stopping the liner collapse process at various intermediate stages, and examining the grain structures in the partially collapsed liners. Well characterized OFE copper shaped-charge liners, assembled into a cylindrical polycarbonate case, of constant length and volume, were partially collapsed, with reduced-weight cylindrical explosive charges. A series of increasing explosive charge weights were used to obtain progressively greater partial deformations on individual copper liners. The shock waves from the varying length explosive charges were coupled to the copper liners through intermediate water fill, which was in direct contact with the rear of the liners. The series of partially collapsed copper liners was captured by ''soft recovery'' in low density polystyrene. Flash radiography prior to liner recovery, confirmed that the unexpected shapes of the recovered partially collapsed liners, actually existed prior to their entering the recovery medium and were not the result of the recovery process itself. This was an early concern when the unusual shapes of the recovered liners were first seen. These shapes were also independently confirmed by a series of computations at Los Alamos National Laboratory, using MESA 2D. A comparison of the photomicrographs of undeformed virgin copper liners and the series of partially collapsed liners, shows regions on the inner apex near the liner axis where plastic flow has occurred, with very substantial modifications (refinement and elongation) in grain structure even for the small deformations which barely change the overall liner shape. Time dependent strain and strain rate computations, using LaGrangean tracer markers, indicate very large strain rates, between 3x10(7)/sec. and 4.7x10(7)/sec. in those regions with plastic flow where grain refinement and elongation are seen, even with very small overall deformation. It is believed likely that this early time material processing and grain refinement, arising from the localized plastic deformation of the liner, plays a key role in preparing the liner material structure, so that it can exhibit the high dynamic ductility, characteristic of copper shaped-charge jets.

At zero temperature the dynamics of the screening process contains an infrared divergence. The broadening of this divergence by temperature causes the motion of the f electrons to crossover from wave propagation to diffusion. This mechanism explains the observed dual nature of the f electrons, namely that at low temperatures they behave like a Fermi liquid, while at high temperatures they evolve into a lattice of localized magnetic moments.

This study also includes calculations for selected alloys using the virtual crystal approximation. The tetragonal shear constant for these elements and alloys is found to follow a trend which can be related to the calculated crystal structure stabilities. In fact, the trend of C' behaves roughly as the the trend displayed by the energy difference between the fcc and bcc crystal structures. The theoretical results are generally in approximately 90% agreement with experiment for the. tetragonal shear constant and this implies indirectly that the discrepancy between theory and experiment found for the crystal energies do not lie in the theoretical data.

As a model system we choose the head-on collision of protons with a nickel atom. For the electronic part of the Hamiltonian we use the most general on-site interaction terms allowed by atomic symmetry. The total electronic many-body states are group-theoretically classified with respect to the conserved quantum numbers L, L(z) and S(z). The time-dependent Schrodinger equation for this system is solved exactly. The zero-, one- and two- electron capture probabilities which are treated on the same footing are monitored along the trajectories of the scattering species on the femtosecond time scale. In good agreement with experiments on surfaces we find probabilities of 22% and 0.33% for one- and two-electron capture respectively and spin polarizations between - 60% and - 100%. The predominant capture of minority electrons is enhanced due to electronic correlations. This implies that the probing of magnetism occurs on a significantly longer time scale than the probing of single electron properties. C1 FREE UNIV BERLIN,INST THEORET PHYS,W-1000 BERLIN 33,GERMANY.

While vanadium impurities suppress the Neel temperature T(N), manganese impurities enhance T(N) substantially. As evidenced by neutron scattering experiments, doping with as little as 0.2% vanadium changes the transition from weakly first order to second order. Young and Sokoloff explained that the first-order transition in pure chromium is caused by a charge-density wave which is the second harmonic of the spin-density wave. By examining the subtle balance between the spin-density and charge-density wave terms in the mean-field free energy, we find that the first-order transition is destroyed when the vanadium concentration exceeds about 0.15%, in agreement with experiments.

The SDW peaks show a distinctly non-cubic distribution that is readily correlated with the ASRO and which corresponds to the propagation of SDW only in the c plane of the tetragonally based ASRO. The high degree of ASRO and single domain character of this carefully heat-treated sample produces an unusually stable SDW with a higher transition temperature and a larger correlation length than is observed for quenched alloys of the same Mn content. Since SDW stability depends on structural features in the conduction electron susceptibility and on flat, parallel sections of the Fermi surface, these observations suggest that the degree of ASRO and/or the presence of single domain ASRO influences the sharpness of the relevant Fermi surface features in these alloys.

During stabilization of these precursors, the methods applied and especially the chemical and physical changes that take place obviously dictate the eventual state of the products' properties. Because small angle x-ray scattering studies reveal the microporous nature of these fibres, the intense scattering patterns are remarkably unique for understanding the changes taking place as the fibres are stabilized. Ammonia was shown to accelerate the stabilization of some precursors. Stabilization of two acrylic fibres was studied both in air and air/ammonia atmospheres. Small Angle x-ray Scattering (SAXS) was used to study the changes of the microstructure. The study showed that the meridianol peaks which are not seen in the precursor fibres appear at the early stages of stabilization and then disappear as the stabilization progresses. The changes took place much faster in the ammonia stabilized samples, indicating the accelerating effect of ammonia. The SAXS scattering patterns also indicated the occurrence of molecular relaxation in the case of fibres stabilized in ammonia, indicating a plasticizing effect of ammonia.

The three major sources of uncertainty in the calculational methodology were numerical approximations, geometric modeling approximations and nuclear data. Nuclear data uncertainties have been identified as the most important source for the differences between calculations and measurements. The iron inelastic cross-section was the dominant source of error, especially in the reactor cavity where the steel penetration was 8-9 in (20.3-22.9 cm).

The approach addresses specific technical and regulatory issues that will arise in the assessment of aging damage during extended operation. Three major issues related to vessel integrity are addressed: pressurized thermal shock events, low upper-shelf energy, and revised pressure-temperature limits. Finally, the approach identifies several options available to manage aging. These options include use of advanced inspection methods to reliably detect and size flaws, flux reduction and thermal annealing to mitigate radiation embrittlement, and supplemental surveillance and material sampling to enhance the database for irradiated reactor pressure vessel materials.

The spin-polarized LCGTO-FF method is described here. Test results are presented for square monolayers of seven 3d-transition metals (Ti, V, Cr, Mn, Fe, Co, and Ni) at the lattice constant of Ag(001). The LCGTO-FF results compare favorably with previous results obtained with the FLAPW technique. (C) 1993 John Wiley & Sons, Inc.

The host lattice is approximated by a small cluster of nickel atoms that are arranged as face-centered-cubic, except for a tubular void described by the absence of three or four lattice elements. The oxygen absorbates are placed, one at time, within this cavity. We conclude that, for tubular cavities, the interaction between the nickel lattice and the oxygen absorbates is stronger than the interactions between pairs of oxygen atoms, suggesting that the absorbates are mostly atomic (as apposed to diatomic) in character, while the (energetically) most preferred number of oxygen atoms to reside inside an n-site, tubular hollow of nickel is simply (n - 1).

Several regions of configuration space where the dynamics is highly sensitive to inaccuracies in the potential have been identified. These regions of importance vary with collision energy, but do not change as dramatically as the previously studied [J. Chem. Phys. 97, 6226 (1992)] collinear case. Near the reaction threshold, the dynamics is most sensitive to the saddle point region as expected. At higher energies (about 1.0 to 1.5 eV), however, the inner corner of the potential, where the dynamics ''cuts the corner'' in going from reactant to product arrangements, is most important for collinear geometries, and the outer corner, where the H-3 conformation is more compact than the transition state conformation, is most important for bent geometries. Surprisingly, the region of the potential traversed by the minimum energy path across the saddle point region has rather insignificant sensitivities at these higher energies.

This intense localized deformation limits the formability of materials and will often quickly lead to failure with continued loading. Localized deformation is often associated with satisfaction of the classical discontinuous bifurcation criterion. Here we propose that the loss of strong ellipticity criterion should be used in place of the classical discontinuous bifurcation criterion as a necessary condition for localization. The application of the strong ellipticity criterion implies that a bifurcation mode associated with loss of positive definiteness of the symmetric part of the acoustic tensor must be identified rather than a mode associated with the first zero eigenvalue of the acoustic tensor itself. The eigensystem for the symmetric part of the tangent modulus tensor is obtained for several different plasticity models. This eigensystem provides information about deformation modes associated with both diffuse and discontinuous bifurcations. Material properties, boundary conditions and body geometry are all shown to affect the diffuse and localized deformation modes that are generated. Numerous experimental observations of necking and localization in metal specimens subject to various boundary conditions are explained with the proposed approach.

This stress intensity factor, referred to here as the free-edge stress intensity factor K(f), can be applied to both plane strain and axisymmetric geometries. This study investigates the potential application of a K(f)-based failure criterion to butt tensile joints. Detailed elastic-plastic finite element calculations for adhesive properties representative of a high strength epoxy indicate that when residual cure stress can be neglected (1) the region dominated by the interface comer singularity is reasonably large relative to adhesive layer thickness, (2) the plastic yield zone is contained within the singular field at nominal failure loads, and (3) the plastic zone size is characterized by K(f) and displays the expected load level and layer thickness dependence. The way uniform adhesive shrinkage (thermal contraction) during cure alters interface comer stress fields is also discussed. When adhesive shrinkage is present, both constant and singular terms must be included in the asymptotic solution to get good agreement with full field finite element results. In general, there is no unique relation between the size of the interface corner yield zone and K(f), although for a prescribed shrinkage strain, K(f) does characterize the extent of plastic yielding. Calculated results suggest that the presence of residual stress can have a considerable effect on the relation between bond thickness and joint strength.

The measured joint strength shows a pronounced bond thickness dependence; joint strength increases by a factor of 2 as bond thickness is reduced from 2.0 to 0.25 mm. A failure criterion, based upon a critical interface corner stress intensity factor, accurately predicts the observed bond thickness effect. This fracture criterion suggests that the strength of an adhesively bonded butt tensile joint of one bond thickness can be estimated from strength data for a joint with a different bond thickness by the simple relation sigma(t2)ult = sigma(t1)ult(h1/h2)1/3, where 2h(i) is bond thickness, sigma(ti)ult is the nominal butt tensile strength, and subscript i = 1, 2 identifies the two joints with differing bond thickness. This relation applies to thin bonds when the adhesive's Poisson's ratio is between 0.3 and 0.4, the adherends are relatively stiff, and small scale yielding conditions hold at the interface corner.

Also included in the data set were data for 39 reference strains representing the genera Aeromonas, Plesiomonas, and Vibrio. Unweighted pair group mathematical averaging cluster analysis resolved nine major groups of operational taxonomic units (OTUs) at simple matching coefficient (S(SM)) values of greater-than-or-equal-to 66.5%. In turn, each group contained one or more OTU clusters (phena) at S(SM) values of greater-than-or-equal-to 72.6%. A total of 27 phena were resolved; 14 phena were identified as Vibrio species and contained 182 of the 236 OTUs in the study. Additional phena were identified as members of the genus Aeromonas (two phena), the genus Photobacterium (three phena), the genus Alteromonas (two phena), and Plesiomonas shigelloides (one phenon). One phenon resembled descriptions of the genera Moraxella and Neisseria and Pasteurella piscicida. The remaining four phena were not identified. The largest phena were identified as Vibrio damsela (52 OTUs) and Vibrio alginolyticus (48 OTUs). Vibrio carchariae and Vibrio harveyi formed subclusters (S(SM) values, greater-than-or-equal-to 82%) within the third largest phenon (24 OTUs), which was resolved at an S(SM) value of greater-than-or-equal-to 72.6%. Human pathogens (e.g., Vibrio cholerae) and fish pathogens (e.g., Aeromonas salmonicida, Pasteurella piscicida, and V. damsela) were isolated from the sharks. Approximately 58% of all of the strains isolated and tested in this study were urease positive. C1 UNIV MARYLAND,SEA GRANT COLL,COLL PK,MD 20742.

An adaptation of quasichemical theory has been proposed which is capable of describing the properties of ordered solutions and of representing the measured properties of binary silicates over broad ranges of composition and temperatures. For simple silicates such as the MgO-FeO-SiO2 ternary system in which silica is the only acid component, a combining rule generally leads to good predictions of the thermodynamic properties of ternary (and probably higher order) solutions from those of the binaries. In basic solutions, these predictions are consistent with those of the Conformal lonic Solution Theory. Our results indicate that our approach could provide a potentially powerful tool for representing and predicting the thermodynamic properties of multicomponent molten silicates. A complete critical evaluation of the thermodynamic properties and phase diagrams of the FeO-MgO, FeO-SiO2, MgO-SiO2 and FeO-MgO-SiO2 systems is presented in which the modified quasichemical model is used for the liquid phase. Optimized equations for the thermodynamic properties of all phases are obtained which reproduce all thermodynamic and phase diagram data to within experimental error limits from 25-degrees-C to liquidus temperatures at all compositions. The optimized thermodynamic properties and phase diagrams are the best estimates presently available. C1 ARGONNE NATL LAB,DIV CHEM TECHNOL,ARGONNE,IL 60439.

The colloidal dispersion of GaAs nanocrystals has been characterized by transmission electron microscopy, electron diffraction, ultrafiltration, optical absorption and photoluminescence spectroscopy, and transient pump-probe spectroscopy; the spectral data were also fitted to a model that accounts for the size-dependent optical properties of a Gaussian distribution of particle sizes. Our results indicate that the spectral region above 470 nm can be assigned solely to GaAs nanocrystals having a mean diameter of 40.0 angstrom with a standard deviation of 9.7 angstrom.

Rational choice of solvent polarity, reaction temperature, concentration of reactants, solution pH, and counterions will determine the size and size distribution of the particles. Sizes of colloidal particles formed in microheterogeneous environments will often be predetermined by the dimensions of the micropores and cavities within the network of the medium. This is the situation in zeolite and clay cavities, and in polymer networks. Self-aggregation of amphiphillic molecules often generates microdomains which may be utilized to direct the particle precursors or the particles themselves into these domains and thus limit their growth. Finally, complexation at the surface of the particles may limit and control the growth processes of the particles. The latter approach also allows functional modification of the particles' surface.

This paper examines the fundamental nature of point and grain boundary defects in this Cu-ternary semiconductor and, for the first time, provides direct evidence underlying the defect chemistry. Special scanning probe microscopy (SPM) techniques are used for real-time atomic imaging, atomic processing (single-atom manipulation), and nanoscale characterization of the same regions of the sample. The (220)-tri-elemental, p-rype surfaces are examined and imaged. Cu-, In-, and Se-vacancies are created using combined, pulsed electric (SPM tip-surface), and single-wavelength photon fields for selected, single-atom removal. The electro-optical characteristics of these defects (before and after creation) are examined using SPM-based nano-photoluminescence and nano-cathodoluminescence techniques that provide information in the same nanometer regime. Bulk photoluminescence spectra are compared and interpreted with respect to these data that give first time direct, atomic-level correlations. In addition, the healing of these point defects by the placement of single intrinsic atoms of the same type at the vacancy sites is accomplished using the atomic processing techniques. The electronic defect levels are verified and correlated with the atomic-scale observations. Finally, donor and acceptor defects, Cu and Se vacancies, Cu at In sites (Cu(In)) and Se at Cu sites (Se(Cu)), are created, evaluated, and characterized. The placement of the acceptor heteroimpurity oxygen at Se vacancies is also examined. This is done both at isolated Se vacancies and at vacancies along electronically active grain boundaries. The passivation of these regions (by p-type doping of the grain boundary) is evaluated using nanoscale electron-beam induced-current (NEBIC), and newly-developed, SPM-based minority-carrier spectroscopy techniques. This paper reports, for the first time, the engineering of these defects on the atomic scale, and complements these results with the direct evaluation of the atomic manipulations using nanoscale electro-optical characterization methods.

Real-time EXAFS measurements during the combustion were made in the time frame of a few seconds. By tuning the monochromator to a specific energy, at which maximum changes occur in an EXAFS feature of an element transforming from the reactant to the product phase, a time resolution of 20 ms was achieved. The Ni + Al -> NiAl reaction has been investigated in some detail in light of a possible intermediate phase in the so-called after-burn region. The present QEXAFS findings together with the recent time-resolved diffraction data on the same system lends, for the first time, experimental insights into the structural macrokinetics of this class of combustion systems.

At the highest sensitivity mode, the random noise of the sensor was equivalent to an input charge of 1500 electrons rms. Feedthrough charge injection associated with TFT switching had to be avoided at the expense of the signal charge. Image lag caused by charge trapping in a-Si was suppressed by limiting the input light intensity. A simple model was developed for the noise contribution from a pixel and compared with measurements.

In the 0-degrees-C as-deposited samples, reaction between Si and Au is minimal, but reaction between Si and Cu is significant Upon annealing for ten minutes in argon, the a-Si crystallized and reacted quite extensively with Au at 160-degrees-C. Further reaction between Si and Cu proceeded at 130-degrees-C. The compounds formed appear to be metal-rich silicides in both the Si/Au and Si/Cu systems.

The interpretation of this instability in terms of a dynamical tunneling model suggests the presence of polarons in these materials.

The valence band splitting and the band gap reduction are calculated for partially ordered samples as a function of the Ga concentration and of the long range order (LRO) parameter. Using polarized photoluminescence, we compare the effect of growth temperature and that of Ga concentration on the LRO parameter. The degree of ordering depends strongly on growth temperature, in the range 600-degrees-C to 725-degrees-C. On the other hand, the change in alloy composition has a minor effect.

There is a very clear splitting of the Al L2 and L3 components (78.38 eV and 78.80 eV) in those spectra. To our knowledge, this is the first report on the Al L23 doublet splitting of single-crystal sapphire obtained from the total-electron yield measurement. All the spectra show similar structure, while the main feature of the RLES is an anticorrelated behavior relative to the TEY and XFY. The edge structures up to 11 eV from the L23 absorption edge are interpreted as due to transition of electron to empty levels of Al ion according to molecular-orbital calculations on the [AlO6]-9 molecules as determined by Balzarotti et al. The post-edge features between 11-60 eV above the Al L23 absorption edge were found to correlate very well with the interatomic distances from the absorbing atom to a neighboring atom as predicted by multiple scattering model of Bianconi and Natoli.

From interfacial free energy considerations, it was postulated that implantation of Cr ions should increase the strength of the bond between iron and sapphire, whereas implantation of Ni ions should weaken the bonds. Implantation of Fe ions should cause changes due to irradiation-produced defects but should exhibit no chemical effect. The pull test was used to evaluate the bond strength of unimplanted and implanted specimens. Since there was large scatter in the data, it was necessary to conduct a statistical analysis. It was assumed that the separation of the film from the substrate was nucleated by interfacial defects in the bond. Because the Weibull analysis was developed to describe the failure probability due to a population of flaw-induced cracks, this technique was used to interpret the data.

Diamond films were grown by a hot filament method as a function of seven different processing parameters: substrate scratching prior to diamond deposition, substrate temperature, methane content of the input gas mixture, filament temperature, filament-substrate distance, system pressure, and total gas flow rate. Adhesion was measured by using a Sebastian Five A tensile pull tester. Testing was complicated by the non-uniformity of the film thickness, diamond quality, film cohesion, and surface preparation across the full substrate surface area. Various types of film failure mode were observed, which did not correlate with the film processing parameters. The measured adhesion values showed larger variations from point to point across the sample surface and from identically prepared samples than variations as a function of the film processing parameters. Weak correlations of adhesion with the processing parameters were found using statistical analysis of the results from multiple pulls on a large number of samples. The statistical results suggest that substrate preparation, gas flow rate, and gas pressure are the most important processing parameters affecting the film adhesion, while the temperature of the hot filament has little or no effect on the adhesion of the film. However, improvements in firm processing and adhesion testing need to be made before true quantitative adhesion testing of high-quality diamond films can be accomplished.

Date of arrival differed significantly among individual males and females. Repeatability for date of return of individual males was (r = 0.0665), but significantly higher for females (r = 0.1662). 4. Snout-vent length had no effect on the date of return for females, but small males returned earlier than large males. 5. We suggest that variation in arrival time for both sexes is determined primarily by environmental variation, but variation among females has a greater potential genetic component. Differing selective pressures between the sexes may contribute to the maintainance of differential amounts of genetic variation. C1 UNIV GEORGIA,SAVANNAH RIVER ECOL LAB,AIKEN,SC 29802.

Positron annihilation line-shape S data are presented as a function of the positron incident energy, gate voltage, and annealing, and are described with a diffusion-annihilation equation for positrons. The data are compared with electrical measurements. Distinct annihilation characteristics were observed at the SiO2-Si interface and have been studied as a function of bias voltage and annealing conditions. The shift of the centroid (peak) of gamma-ray energy distributions in the depletion region of the MOS structures was studied as a function of positron energy and gate voltage, and the shifts are explained by the corresponding variations in the strength of the electric field and thickness of the depletion layer. The potential role of the positron annihilation technique as a noncontact, nondestructive, and depth-sensitive characterization tool for the technologically important, deeply buried interface is shown.

Radical scavenging properties have attracted much attention in this field. This article discusses the implication of antioxidant properties of the antihypertensive diuretic indapamide on renal injury in Dahl salt-sensitive (Dahl S) rats. Hydroxyl radicals, oxygen radicals toxic to cellular membranes, are eradicated by indapamide in different assay systems, e.g., reduction of alpha-alpha-diphenyl-beta-picrylhydrazyl, rat brain homogenate, or xanthine-xanthine oxidase systems. Such antioxidant effects of indapamide are primarily due to inhibition of lipid peroxidation induced by hydroxyl radicals, and this mechanism may stimulate prostacyclin generation through activation of prostacyclin synthase. In fact, the antioxidant properties of indapamide are well expressed in vivo as well; indapamide treatment reduced oxygen radicals in the kidney of Dahl S rats with hypertension. This was accompanied by a functional improvement of the kidney; decreases in urinary protein and n-acetylglucosaminidase excretion and an increase in glomular filtration rate were observed. In addition, indapamide morphologically ameliorated the renal injury, and decreased glomerular sclerosis score, arterial injury, and renal tubular injury. Trichloromethiazide reduces blood pressure similar to that produced by indapamide. However, trichloromethiazide did not lead to reduction of oxygen radicals in the kidney, and did not improve the functional disturbance or morphological injury seen in Dahl S rats. These results indicate that indapamide has antioxidant properties, and in addition to blood pressure reduction, such radical scavenging effects may contribute to its beneficial effects on renal function in vivo.

Thus, the DNA-carcinogen adduct has been used as a measurable biochemical endpoint in laboratory studies designed to assess carcinogen exposure, carcinogen metabolism, mutagenesis, and tumorigenesis. Unfortunately, the significance of adducts in the etiology of human cancer is still unclear. This is partially due to the difficulty detecting adducts at carcinogen exposures relevant to humans, which are often orders of magnitude lower than animal model exposures. The relationship between adducts and higher biological effects is also not known at low doses. We have been assessing the DNA damage caused by exposure to heterocyclic amine carcinogens in the diet. Using the technique of P-32-postlabeling in combination with accelerator mass spectrometry, we have determined that DNA adduction in rodents decreases linearly with decreasing dose from the high doses used in typical cancer bioassays to the low doses relevant to human exposures. For a given tissue, adduct levels are correlated with dose, but the level of DNA modification by carcinogens is tissue-specific and does not completely correlate with tumor site. This lack of correlation may be due to differences in adduct formation and repair rates among tissues. Comparison of carcinogen metabolism routes between rodents and humans also indicates that species differences could influence the amount and type of damage resulting from exposure to these carcinogens. The use of model systems to study dosimetry, species differences in adduction, and role of adducts in mutation will ultimately lead to a better understanding of the significance of adducts in human disease. This should eventually allow the use of adducts as biomarkers for estimating carcinogen exposure and individual susceptibility.

Compression measurements were made at six temperatures from -54 to +74-degrees-C and at many pressures up to 70 MPa. The volume coefficient of expansion of the paste at 1 atm is very nearly constant over the temperature range tested, averaging (3.643 +/- 0.005) X 10(-4) K-1. In compression tests, at a given volume, the observed pressure was 3-15 MPa higher when pressure was rising than when it was falling, possibly because of O-ring drag. The specific volume of the paste over the field of temperature and pressure was well described by a simple equation of state: v/(cm3 g-1) = 0.50977 + 0.16683(T/K)/(P/MPa + 801.41), s(e)(v/(cm3 g-1)) = 0.00026.

These solubilities are important to an electrolytic production of uranium metal by a process similar to the Hall-Heroult process for aluminum. Data reported in the technical literature were supplemented by new measurements. The solubilities of UO2 are low at low UF4 concentrations and are approximately proportional to UF4 concentrations for the 0.02-0.5 mol fraction UF4 range of interest for electrolytic cell operation. New data for CaF2 + LiF + UF4 over this range show solubilities of 0.11 mol of UO2/mol of UO2 + UF4 as compared to about 0.07 mol of UO2/mol of UO2 + UF4 for BaF2 + LiF + UF4. Our data did not show the anomalous increase in UO2 solubility for decreasing UF4 concentration that had been reported for CaF2 + LiF + UF4 mixtures.

Late erythroid cells express mainly the downstream initiation site for synthesis of prototypical 80-kD isoforms; nonerythroid cells in addition use an upstream site to encode higher molecular mass isoform(s). In this study, we examined the effects of a 5' gene rearrangement in a family with hereditary elliptocytosis and complete deficiency of erythrocyte 4.1 protein on 4.1 isoform expression in erythroid vs. non-erythroid cells. Patient 4.1 mRNAs from reticulocytes, fibroblasts, and B lymphocytes were amplified by reverse transcriptase/polymerase chain reaction techniques and shown to exhibit a 318-nucleotide deletion that encompasses the downstream AUG, but leaves intact the upstream AUG. Immunoblot analysis revealed a total deficiency of 4.1 in patient red cells and a selective deficiency of 80-kD isoform(s) but not high molecular weight 4.1 in patient nonerythroid cells. Thus, the 4.1 gene mutation in this family produces an isoform-specific deficiency that is manifested clinically in tissue-specific fashion, ion, such that red cells are affected but other cell types are unaffected because of tissue-specific differences in RNA splicing and translation initiation.

The 80-kD protein 4.1 is an important organizational component of this membrane skeleton. Recently, it has been recognized that multiple structural isoforms of 4.1 are encoded by a single gene via alternative pre-mRNA splicing, and that an upstream ATG can be spliced in and used for translation of high molecular weight 4.1. We are exploring the hypothesis that differentiation-associated switches in protein 4.1 structure play an important role in membrane reorganization. To study changes in 4.1 gene expression during normal human differentiation, we analyzed 4.1 protein and mRNA structure at various developmental stages. Using immunofluorescence microscopy, we observed high molecular weight 4.1 isoforms in preproerythroblasts producing punctate, predominantly cytoplasmic staining with a perinuclear area of intense fluorescence, while mature red cells expressed very little high molecular weight 4.1. Isoforms containing an alternatively expressed 102-nucleotide exon near the COOH terminus were abundant in both preproerythroblasts and mature cells but produced a punctate distribution of fluorescence over the entire preproerythroblast and intense membrane-associated fluorescence in the erythrocyte. Characterization of RNA by polymerase chain reaction and nuclease protection assays revealed a differentiation-associated switch in pre-mRNA splicing in the spectrin-actin binding domain. Since this domain plays a critical role in regulating membrane material properties, we speculate that this switch may be crucial to reorganization of the skeletal network during erythropoiesis. We conclude that 4.1 isoforms are differentially expressed and differentially localized during erythropoiesis, and that this isoform family is likely to have diverse functions during terminal differentiation.

The perfectly conducting external tangential magnetic field distribution is used in an internal Green's theorem representation to determine the axial electric field. The corner constant is then determined by an integration of the surface axial electric field and the perfectly conducting magnetic field. Expansions of the axial electric field are also given because of its utility in future papers. A rotation of the radial coordinate into complex values is used to reduce the corner constant to a known complex phase times a real constant. This rotation is valid for general real ratios of internal to external magnetic permeabilities as a result of the analyticity of the fields in a sector above the positive real axis of the radial coordinate.

This paper surveys a number of yet-unexploited classes of semiconductors, pointing to the much-needed research in screening, growing, and characterizing promising members of these classes. In light of the unmanageably large number of a-priori possibilities, we emphasize the role that structural chemistry and modem computer-aided design must play in screening potentially important candidates. The basic classes of materials discussed here include nontraditional alloys, such as non-isovalent and heterostructural semi-conductors, materials at reduced dimensionality, including superlattices, zeolite-caged nanostructures and organic semiconductors, spontaneously ordered alloys, interstitial semiconductors, filled tetrahedral structures, ordered vacancy compounds, and compounds based on d and f electron elements. A collaborative effort among material predictor, material grower, and material characterizer holds the promise for a successful identification of new and exciting systems.

Solidification history determines the metallurgical state, and can be partially derived from macroscale simulation. This requires realistic initial conditions-weld pool temperatures and flows at power off time-in order to produce accurate solidification histories for the pool points. Numerical simulation of the heat and mass tranfer is carried out here with a finite volume finite difference scheme on a flat surfaced pool (appropriate for currents of present interest). Suface tension, buoyancy and Lorentz forces are included in the flow model. When the arc heating and Lorentz forces are shut off, continuation of the calculation allows examination of the solidification thermal environment. Welds on stainless steel are simulated with fluid flow driven by an ''effective'' surface tension coefficient of partial derivative gamma/partial derivative T = -0.01 dyne/cm K. Solidication events consist of an initial phase which smooths the fusion zone boundary and removes the superheat from the pool, followed by a quasisteady stage, and end with a terminal boundary layer with time dependence similar to the singular spherical Stefan solution. Introduction of ''numerical macrographs'' allows convenient comparison of simulated conditions with actual weld macrographs. RP BERTRAM, LA (reprint author), SANDIA NATL LABS,LIVERMORE,CA 94551, USA.

Here we discuss the theory and rationale for such an approach and then present the results of a field study to test its efficacy at the Idaho National Engineering Laboratory (INEL). We examined the capacity of four species of perennial plants to deplete soil moisture on simulated waste trenches and determined the effective water storage capacity of the soil. Those data enabled us to estimate the minimum depth of fill soil required to prevent deep drainage. Any of the species studied can use all of the plant-available soil water, even during a very wet growing season. The water storage capacity of the soil studied is 17% by volume, so a trench cap of 1.6 m of soil should be adequate to store precipitation received at the INEL while plants are dormant. We recommend a fill soil depth of 2 m to provide a margin of safety in case water accumulates in local areas as a result of heavy snow accumulation, subsidence, or runoff. Fill soil requirements and choice of plant species will vary, but the concepts and general approach are applicable to other shallow land burial sites in arid or semiarid regions.

During the production of O3 using electrical discharge generators fed with dry air, there is an inadvertent addition of HNO3 vapor, a highly reactive trace gas. While several studies have proposed that HNO3 vapor introduces artifacts, none has measured concentrations of the odd-N2 trace gas in the chamber or investigated the fate of the N in the context of whole-plant physiology and growth. These questions were investigated using open-top chambers containing seedlings of loblolly pine (Pinus taeda L.) during the 1988 growing season in Oak Ridge, TN. The O3 treatments consisted of charcoal-filtered or subambient (0.96 mumol m-3, 24-h mean), ambient (1.62 mumol m-3, 24-h mean), and elevated (2.36 mumol m-1, 24-h mean) concentrations, the last being accomplished by proportional O3 addition over the diurnal period. Measurements of the HNO3 vapor concentration during dry periods only (no rainfall or ground-level fog) averaged 28.6 nmol m-3 (subambient), 55.4 nmol m-3 (ambient air), and 240.0 nmol m-3 (elevated O3), an 8.4-fold range. For every 100 mol of O3 added to the chamber, 28 mol of HNO3 vapor were inadvertently added; this ratio is several times higher than that previously reported. This result, taken with published estimates of leaf conductance to HNO3 vapor, indicates a maximum N deposition in the form of HNO3 vapor ranging from 19.5 pmol N cm-3 leaf area h-1 (subambient O3) to 171.9 pmol N cm-2 h-1 (elevated O3). Given the nutrient content of the seedlings and knowledge of the fate of HNO3 vapor on the leaf surface and leaf interior, the degree to which N deposition via HNO3 vapor met the N requirements of the loblolly pine seedlings was estimated. Seedlings in the elevated O3 treatment had an upper-limit estimate of 3.5% for the needles and 1.8% for the whole plant of N derived from HNO3 vapor. The concentration of HNO3 vapor in the chambers, site of HNO3 vapor deposition, N requirements of the loblolly pine seedlings, and estimated threshold for phytotoxic effects of HNO3 vapor indicate that the inadvertent production of this odd-N2 trace gas is important in understanding the atmospheric chemistry within the chambers, but that the level of N loading in this study is unlikely to affect physiology or growth. However, we recommend that studies that employ higher O3-exposure scenarios recognize the potential for inadvertent N deposition, particularly in trees grown in N-deficient substrate.

Microbial transformations of chelates in the subsurface are currently unknown, but could influence chelate persistence and thus alter the transport of radionuclides. Surface soil and subsurface sediments from five formations (36- to 376-m depth) were collected near Allendale, SC. Aerobic mineralization of C-14-labeled EDTA, DTPA, and NTA occurred in select sediments indicating that subsurface microorganisms can degrade chelates, whereas chelates may be relatively stable in strata where limited mineralization occurred. The chelates were not mineralized more rapidly or to a greater extent in the surface soil than in the subsurface sediments. The relative order of chelate persistence was EDTA > DTPA > NTA, with the maximum amount mineralized during 115 d at 15, 26, and 43%, respectively. Maximum mineralization of all three chelates did not occur in the same sediment, indicating that different microbial populations were responsible for the degradation of each chelate. Mineralization of chelates was minimal under denitrifying conditions and was reduced when additional soluble C was added. There was no relationship between chelate mineralization and the adsorption of chelates to sediments or the aqueous speciation of the chelates.

Our results indicate that current land-based emissions are of the order of 152 million tons each year. Reducing forestation by 50 percent could lower emissions to twenty-one million tons. With regard to specific land use policies, we estimate that agroforestry, if adopted at a rate of 2 to 4 percent annually, could reduce annual carbon emissions by about thirty-eight to sixty-six million tons. Offsetting industrial roundwood removals or converting 0.1 percent of high and medium productivity land back to forest each year could result in the sequestration of about eleven to eighteen million ions annually. The direct costs of carbon sequestration are estimated at $3 to $22 per ton depending on the land use policy.

Over 84% of the plasmoid events occurred between 5 and 60 min after a substorm onset. We also find near one-to-one correlation between large isolated substorm signatures in the near-Earth region and signatures consistent with a passing plasmoid in the distant tail (i.e., a traveling compression region, or an actual plasmoid observation). However, there does not appear to be an absolute correspondence of every substorm onset to a plasmoid signature in the deep tail especially for periods of prolonged disturbance that have multiple substorm onsets. A correlation of interplanetary magnetic field B(z) south with plasmoid observations was also found. The locations of the near- and far-Earth reconnection sites are estimated using the time of flight of the plasmoids from substorm onset to their observation at ISEE 3. The estimates of the near- and far-Earth reconnection sites are highly variable and range from 10 to 140 R(E). C1 LOS ALAMOS NATL LAB,SPACE PLASMA PHYS GRP,LOS ALAMOS,NM 87545.

A STATISTICAL-SURVEY SO JOURNAL OF GEOPHYSICAL RESEARCH-SPACE PHYSICS LA English DT Article ID PLASMA SHEET BOUNDARY; NEUTRAL SHEET; EARTHS MAGNETOTAIL; SUBSTORM; FLOW; RECONNECTION; PARTICLES; ISEE-1; LAYER; LINE AB During 1978 and 1979, the medium energy particles experiment on board the ISEE 2 spacecraft (apogee 22.7 R(E)) collected almost 122 days of data in the central region of the Earth's magnetotail. We have surveyed 16-s averages of the energetic ion (E > 25 keV) and plasma measurements in order to establish the statistical properties of high ion anisotropy events (\A\ > 1) which are frequently observed in the near-Earth plasma sheet. Our major findings from the analysis of 1944 high-anisotropy samples (HAS) are as follows: (1) Strong energetic ion anisotropies are not maintained over long periods of time but occur in bursts lasting for fractions of a minute up to a few minutes. (2) For almost 80% of the HAS, the anisotropy vector points either earthward or tailward rather than across the tail. (3) The ratio of HAS toward the Earth and HAS toward the tail is approximately 4.8:1. (4) The probability of observing high-anisotropy events is well enhanced beyond approximately 16 R(E) downtail distance, on the duskside, and close (within 2 - 3 R(E)) to the neutral sheet. (5) Strong tailward anisotropies can be observed anywhere in the near-Earth plasma sheet. However, their occurrence frequency is considerably above average beyond x(SE) almost-equal-to -19 R(E) and within 2 R(E) of the neutral sheet. (6) Both plasma bulk flow and ion anisotropy at higher energy (> 115 keV) are generally in the same direction as the energetic ion anisotropy at E > 25 keV. (7) Streaming energetic electron populations in the same direction as the ions are significantly more often observed when the ions are streaming tailward than simultaneously with earthward streaming ions when the electrons are usually isotropic. We conclude that statistically the observation of strong tailward ion streaming indicates the existence of a particle source in the near-Earth magnetotail between the spacecraft and the Earth. Certain features suggest that this source might be identical with a near-Earth magnetic neutral line. C1 LOS ALAMOS NATL LAB,LOS ALAMOS,NM 87544. MISSION RES CORP,LOS ALAMOS,NM.

MAGNETIC-FIELD AND SUBSTORM CHARACTERISTICS SO JOURNAL OF GEOPHYSICAL RESEARCH-SPACE PHYSICS LA English DT Article ID PLASMA SHEET BOUNDARY; MAGNETOSPHERIC SUBSTORMS; MAGNETOTAIL RECONNECTION; NEUTRAL LINE; ISEE 1; LAYER; FLOW; MODEL; ACCELERATION; SIMULATIONS AB In a companion paper we have reported results from a survey of strong energetic ion (E > 25 keV) anisotropies in the central geomagnetic tail based on 2 years of data from the SEE 2 spacecraft. Here we extend this study with particular emphasis on the relation of high ion anisotropies to recent models of geomagnetic substorms and include magnetic field and ground-based data. Beyond 16 R(E) downtail distance, we find a correlation between the magnetic field north-south component (B(z)) and the streaming direction of the energetic ions. Earthward ion streaming is observed almost exclusively when B(z) is positive while tailward streaming tends to occur with negative B(z). Strong ion anisotropies are magnetic field aligned rather than perpendicular to it suggesting that most of them are observed at the plasma sheet boundary. However, they are also found in the central plasma sheet. A superposed epoch analysis using the AL index yields a relation between substorm phases and the observation of high ion anisotropies. Earthward streaming at larger distances from the Earth and/or the neutral sheet usually occurs during substorm recovery while earthward streaming closer to the Earth and tailward streaming events are related to the substorm expansion phase. Three events characterized by strong tailward ion and plasma streaming detected first changing to earthward streaming later on are presented in some detail. The overall features of two of these events strongly suggest the formation of a magnetic neutral line earthward of the satellite at substorm onset moving tailward around recovery. While most observations during the third event also indicate such a sequence, there are some puzzling details which do not match this interpretation. Although a certain B(y) signature proposed by numerical simulations of near-Earth reconnection could not be found, we conclude that the statistical properties of strong ion anisotropies can consistently be explained in terms of the near-Earth neutral line model of substorms if the substorm neutral line sometimes forms well inside the ISEE orbit. Other recently published models of substorm onset such as the thermal catastrophe model and the current disruption model can also account for part of the observations but still require further refinement.

Within the horns, magnetic field lines of increasing geomagnetic latitudes map to increasing distances into the downtail plasma sheet. Plasma data from the fast plasma experiment on ISEE 2 have been analyzed for 11 outbound crossings of the horns in the premidnight sector of the magnetosphere at typical altitudes of approximately 2-4 R(E). These crossings typically occurred on time scales of less than 1 hour, providing almost instantaneous snapshots of plasma gradients within the horns. Ion temperatures observed during these crossings generally decreased by a factor of 4-8 as magnetic field lines of increasing geomagnetic latitude were traversed. If we make the reasonable assumption that the ion temperatures are constant along the field lines within the plasma sheet, then this result implies that the ion temperatures in the downtail plasma sheet also commonly decrease by this same factor over the radial range extending from the inner edge of the plasma sheet at the plasmapause boundary to the outer edge at a neutral line in the distant tail.

More than 100 individual deaths were aged, and/or autopsied and analyzed for toxic compounds, and the population was surveyed for size and structure. Arctic belugas and other species of whales and seals from the St. Lawrence were used for comparison. Population dynamics: Population size appeared to be stable and modeling showed this stable pattern to result from low calf production and/or low survival to adulthood. Toxicology: St. Lawrence belugas had higher or much higher levels of mercury, lead, PCBs, DDT, Mirex, benzo[a]pyrene metabolites, equivalent levels of dioxins, furans, and PAH metabolites, and much lower levels of cadmium than Arctic belugas. In other St. Lawrence cetaceans, levels of PCBs and DDT were inversely related to body size, as resulting from differences in metabolic rate, diet, and trophic position, compounded by length of residence in the St. Lawrence basin. St. Lawrence belugas had much higher levels than predicted from body size alone; levels increased with age in both sexes, although unloading by females through the placenta and/or lactation was evidenced by overall lower levels in females and very high burdens in some calves. No PCDDs and only low levels of some PCDFs were detected in St. Lawrence belugas, while proportions of toxic non-ortho (coplanar) PCBs were low relative to proportions seen in other species. At least ten different PCB methylsulphone metabolites were detected in St. Lawrence belugas. Levels of B[a]P adducts to DNA in St. Lawrence beluga brain and liver approached those associated with carcinogenis in small laboratory animals. Pathology: St. Lawrence belugas were not emaciated, and major findings were: a high prevalence of tumors (40% of animals) including eight malignant neoplasms; a high incidence of lesions to the digestive system (53%), to the mammary glands (45% of adult females), and to other glandular structures (11%); some evidence of immuno-suppression; frequent tooth loss and periodontitis. Two animals had severe ankylosing spondylosis and another was a true bilateral hermaphrodite. No such lesions were observed in 36 necropsies of Arctic belugas and of seals and cetaceans from the St. Lawrence. C1 FAC MED VET ST HYACINTHE,ST HYACINTHE J2S 7C6,PQ,CANADA.

From each initial condition a nominal retrieval trajectory is determined, which is implemented with the tether reel and requires nominally zero thrusting. The retrieval dynamics of the TSS are unstable, and open loop retrieval by itself is not practical. Consequently, a loop structure is designed that combines feedforward information with thruster actuated feedback stabilization. The tether-normal thrusters mounted on the subsatellite are used to stabilize the in-plane and out-of-plane dynamics along the precomputed trajectory. A Kalman filter is used to estimate pitch and pitch rate from a noisy pitch sensor. This whole design yields fast retrievals, limited primarily by constraints on docking speed and tether tension. Thruster fuel use is driven by sensor noise, rather than by the need to remove system angular momentum. Numerical results clearly indicate that, to limit fuel use, system pitch attitude must be measured with a resolution much better than the 2 deg currently planned.

Emergency groups as well as citizens in surrounding communities need to know the relative effectiveness of various chemical protective clothing (CPC) ensembles in the unlikely event of such releases. A method has been developed for studying permeation of chemical warfare agent simulants through CPC materials. The experimental results characterize some commercially available CPC materials. Thirteen different CPC materials having widely differing compositions were chosen to study the permeation of four different liquid CW simulants (dimethyl methyl phosphonate, diisopropyl methyl phosphonate, malathion, and dibutyl sulfide) through these CPC materials at 25-degrees-C. This permeation study involved a newly developed analytical technique employing room temperature fluorescence quenching of an indicator compound, phenanthrene, on filter paper. Various experimental factors such as breakthrough time, rate of permeation and uptake were investigated. On the basis of breakthrough time, the 13 CPC materials could be divided into three groups: most resistant, moderately resistant, and least resistant. Materials in the most resistant category exhibited no permeation by any of the simulants for at least 24 hours. Breakthrough occurred in the least resistant materials in generally less than an hour, and sometimes as soon as a few minutes.

In HepG2 conditioned medium (CM), 60-70% of apoA-I is in the d > 1.235 g/ml fraction (lipid-poor apoA-I); hence we investigated whether inclusion of d > 1.235 g/ml fraction in LCAT incubations altered HDL subpopulations. After 18 h incubation of CM (containing lipoproteins and d > 1.235 g/ml fraction) with purified LCAT, the major transformation product on GGE was a large 9.7-nm particle (HDL2b pattern); a minor component appeared at 7.4 nm (HDL3c). Differences in particle size distribution between CM and isolated lipoprotein incubations were not the result of differences in LCAT activity; mass ratios of unesterified cholesterol:cholesteryl ester and phospholipid:cholesteryl ester were similar. Removal of apoA-I from the d > 1.235 g/ml fraction by immunoaffinity chromatography prior to incubation with the d < 1.235 g/ml fraction produced the same products (i.e., HDL2b pattern) as incubations performed with the unaltered d > 1.235 g/ml fraction; therefore, lipid-poor apoA-I does not influence nascent HDL transformation. Cholesteryl ester was transferred from HepG2 HDL to LDL in CM incubations; however, cholesteryl ester transfer protein was not immunochemically identified. Removal of HepG2 LDL from CM prior to incubation with LCAT still resulted in the HDL2b pattern. We conclude that HepG2 cells secrete a factor(s) that modifies nascent HDL transformation products into a predominantly HDL2b subpopulation.

Primary results show that the HL capillary gel was simple to cast, and its stability was reasonably good under our running conditions. In the non-gel CE experiment, a buffer containing the sieving additive hydroxypropylmethyl cellulose was used to affect the size-dependent separation. The use of GC capillaries eliminates the inconvenience of separately coating the capillary walls for efficient non-gel separation. Finally, we demonstrate that it is feasible to detect native DNA fragments using indirect fluorometry in non-gel capillary electrophoresis. C1 IOWA STATE UNIV SCI & TECHNOL,DEPT CHEM,AMES,IA 50011.

Moreover, two of the six polymer derivatives were acetylated for amine charge neutralization. Dynamic light scattering results indicate that the unmodified polymers assume the most extended and probably most highly aggregated structure in aqueous solution (100 mM Tris-NHl, pH = 6.8). Attachment of decyl groups on the primary amines has little effect on the solution properties of the polyethyleneimine polymers; these modified polymers are most similar to the unmodified polymers. In contrast, attachment of dodecyl or dodecylbenzyl groups on the tertiary amines induces the polymers to contract. In addition these polymers do not seem to aggregate as extensively as the unmodified polymers. Results demonstrate the utility of dynamic light scattering measurements to provide novel insight into effects of relative hydrophobicity of polyethyleneimine polymers on their extension and aggregation tendencies in aqueous solution. These results may provide a basis for understanding the enzymatic properties of polyethyleneimine polymers. C1 ARGONNE NATL LAB,DIV BIOL & MED RES,ARGONNE,IL 60439.

These coatings exhibit excellent wear and corrosion resistance; however, the significance of microstructure on properties has not been reported. This study relates the structure of the sprayed coatings to the processing conditions. X-ray diffraction results indicate phase separation in air plasma sprayed deposits, while low pressure plasma sprayed deposits exhibit a single supersaturated solid solution. Annealing of the air plasma sprayed coating shows dissolution of the bcc chromium phase, confirming its metastable nature. These results were confirmed using Extended X-ray Absorption Fine Structure (EXAFS) analysis, which further suggests a highly disordered structure, with partial oxidation of selected alloying elements, such as chromium. Transmission electron microscopy indicates a wide variety of microstructures in the air plasma sprayed deposit. In the case of low pressure sprayed deposit, the microstructures are homogeneous and uniform. C1 USN,RES LAB,WASHINGTON,DC 20375. SANDIA NATL LABS,ALBUQUERQUE,NM 87185. SFA INC,LANDOVER,MD 20785.

The PbTiO3 films grown at temperatures below T(C) (approximately 500-degrees-C) are c-axis oriented polycrystals, while the PbTiO3 films growth ai temperatures above T(C) are single crystals with a bi-layer structure at room temperature. The top layers of the films near the free surface are c-axis oriented with the orientation relationship of (001)[100]PbTiO3//(001)[100]MgO. The bottom layers of the films near the substrate are a-axis oriented with the orientation relationship of (100)[001BAR]PbTiO3//(001BAR)[100]MgO. The formation of the bi-layer microstructure of the PbTiO3 films will be discussed in terms of the effect of the cooling rate and the substrate on the phase transition of PbTiO3 from the cubic to the tetragonal phase. When the PbTiO3 films were grown with a large excess of the Pb precursor vapor in the vapor mixture, PbO and PbTiO3 coexisted in the films. Both PbO and PbTiO3 were grown epitaxially on (001)MgO. The epitaxial orientation relationships were found to be (100) [001]PbO//(001)[100]MgO and (001) [100]PbTiO3//(001)[100]MgO. The 90-degrees domains were observed in the PbTiO3 films deposited at temperatures above T(C). The domain walls are the {101} and {011} twin boundaries, which were formed during the phase transition from the cubic to the tetragonal phase. C1 ARGONNE NATL LAB,DIV MAT SCI,ARGONNE,IL 60439.

The method is readily implemented by instituting a step change in the CE electric field strength for desired periods of time during a separation. As a result, the m/z range or the number of times an m/z range can be scanned while a solute elutes is increased by a factor proportional to the decrease in CE electric field strength. In addition, the method is shown not to cause any significant loss in separation quality as demonstrated for mixtures of proteins and peptides, while providing an effective gain in sensitivity. This allows an enhancement in the quality of mass spectra recorded while scanning wide m/z ranges. Mass spectra for a set of standard proteins were obtained for injections of 60 femtomole/protein, while analysis of an albumin tryptic digest was obtained for injections corresponding to 40 femtomoles of protein.

The investigation of conditions that can trap the M-state intermediate in the bacteriorhodopsin (bR) photocycle has revealed, however, that when glucose-embedded bR is prepared at ambient humidity, it does not fully retain the capability to execute a proper photocycle. However, 'native' photocycle properties are returned after glucose-embedded samples are equilibrated at 81% relative humidity. Equilibration at relative humidities significantly higher than 81 % causes glucose to dissolve in its own water of hydration, resulting in samples that may be too thick to be suitable for electron microscopy. The results obtained with bR indicate that caution should be taken with other biological specimens, and it cannot be assumed that glucose-embedded biological macromolecules retain completely their native, hydrated structure, even when high-resolution electron diffraction patterns are obtained. Equilibration of such samples at high humidity may generally be a worthwhile precaution when using the glucose-embedding technique. C1 LAWRENCE BERKELEY LAB,DIV CELL & MOLEC BIOL,BERKELEY,CA 94720.

The model uses multitemperatures for thermal nonequilibrium and non-zero chemical affinities as a measure of the deviation from chemical equilibrium. The plasma is treated as an ideal gas with the Debye-Huckel approximation employed for pressure correction. The proration method is used when the cutoff energy level is between two discrete levels. The composition and internal partition functions of a hydrogen plasma are presented for electron temperatures ranging from 5000 to 35000 K and pressures from 0.1 to 1000 kPa. Number densities of 7 different species of hydrogen plasma and internal partition functions of different energy modes (rotational, vibrational, and electronic excitation) are computed for three affinity values. The results differ from other plasma properties in that they 1) are not based on equilibrium properties; and 2) are expressed as a function of different energy distribution parameters (temperatures) within each energy mode of each species as appropriate. The computed number densities and partition functions are applicable to calculating the thermodynamic, transport, and radiation properties of a hydrogen plasma not in thermal and chemical equilibria. The nonequilibrium plasma model and plasma compositions presented in this paper are very useful to the diagnosis of high-speed and/or low-pressure plasma flows in which the assumptions of local thermal and chemical equilibrium are invalid.

The theory is based on the hydrodynamic approach of Maxwell and Stefan, as extended and elaborated by Furry [1] and Williams [2]. The present development further extends these earlier treatments to multiple temperatures and multicomponent thermal diffusion. The resulting diffusion fluxes obey generalized Stefan-Maxwell relations which include the effects of ordinary, forced, pressure, and thermal diffusion. When thermal diffusion is neglected, these relations have the same form as the usual single-temperature ones, except that mole fractions are replaced by pressure fractions (i. e., ratios of partial pressures to total pressure). The binary and thermal diffusion coefficients are given in terms of collision integrals. Single-temperature systems and binary systems are treated as special cases of the general theory. A self-consistent effective binary diffusion approximation for multitemperature systems is presented. RP RAMSHAW, JD (reprint author), EG&G IDAHO INC,IDAHO NATL ENGN LAB,IDAHO FALLS,ID 83415, USA.

Within the spinel crystal structure, numerous interstices characterized by octahedral anion coordination are intrinsically unfilled by cations. For implantation at 300 K, a typical helium atom locates centrally in one of these vacant octahedral interstices with a probability of approximately 95%. Significant occupation of other lattice sites of either high or low symmetry was rejected. In particular, helium neither clusters in defect complexes nor locates in tetrahedral interstices or substitutional sites.

Phosphorus is shown in these simple alloys to exert its primary influence while in solution. Phosphide precipitation appears to play only a secondary role in void swelling. The role of cold-work is not always to suppress swelling in Fe-Cr-Ni and Fe-Cr-Ni-P alloys, however, particularly at relatively higher irradiation temperatures, where cold-working often increases swelling substantially.

The hardness was increased by up to 51% in AlN and 84% in SiC. The hardness decreased after annealing at temperatures around the irradiation temperature. At the same temperatures, the macroscopic length, which was increased by irradiation, also began to decrease. The hardness and length were almost recovered after 1,200 - 1,400-degrees-C annealing. Thus, hardening in irradiated AlN and SiC is controlled by the number of point defects, or, more precisely, by the strain caused by small point defect clusters which pin down dislocation movement. Dislocation loops were still observed in some samples after 1,400-degrees-C annealing while the hardness was almost recovered to that in the unirradiated state. Thus, the existence of dislocation loops is not grounds for hardening in irradiated AlN and SiC. C1 CASE WESTERN RESERVE UNIV, SCH MED, DEPT MAT SCI & ENGN, CLEVELAND, OH 44106 USA.

The dispersion of a nonuniform slug flowing in a porous medium. J. Pet. Sci. Eng., 8: 293-301. Analytical solutions to the convection-dispersion equation are provided for the time-dependent dispersion of a nonuniform slug, flowing axially in a porous medium. Both longitudinal and transverse dispersion in a porous medium of finite radius and infinite or semi-infinite length are considered in this unit mobility ratio displacement process. Inasmuch as these solutions, which are also given in rectangular coordinates, are the only ones which incorporate the transient ad steady-state solutions, transverse and longitudinal dispersion, and boundary effects for a nonuniform slug of solvent, they provide an excellent means of evaluating the accuracy of numerical simulators. Previous solutions to the convection-dispersion equation for the longitudinal dispersion of uniform slugs can be obtained from these expressions by imposing the appropriate constraints.

When the effects of size disorder are added to the theory in a similar way to vibrational (thermal) disorder and atomic radii derived from experiment are used as input, one can accurately predict alloy melting temperatures. In contrast, when this approach is used with atomic radii derived from ab initio pseudopotentials, it fails to recreate the experimental melting curves. Although the added size disorder term is itself explicitly independent of temperature, a functional temperature dependence of the radii is necessary to reproduce accurately the melting data.

Explosion has been simulated in 13 of these and the final nucleosynthetic yields, including the nu-process, determined. Except for the products of the neutrino process (fluorine and boron), the presupernova abundances of isotopes lighter than about A = 40, closely resemble the final yields. These results, when incorporated into a model for Galactic chemical evolution that includes contributions from lower mass stars and Type Ia supernovae, give present day abundances that are in good agreement with those observed in the solar system when a particular choice is made for the C-12(alpha, gamma)O-16 reaction rate (S(300 keV) = 0.17 MeV barns). We find primary nitrogen is produced for zero metallicity stars whose mass is 30 M. or greater. Some preliminary predictions of the evolution of N, O, Na, Al, Mg, and Fe as a function of metallicity are presented. C1 LAWRENCE LIVERMORE NATL LAB,DEPT PHYS,GEN STUDIES GRP,LIVERMORE,CA 94550.

Hence, the histogram of interspike intervals (ISIH), i.e., of times between successive firings, is multimodal for these neurons, with peaks centered at integer multiples of the driving period. A particular kind of residence time histogram for a large class of noisy bistable systems has recently been shown to exhibit the major features of the neural data. In the present paper, we show that an excitable cell model, the Fitzhugh-Nagumo equations, also reproduces these features when driven by additive periodic and stochastic forces. This model exhibits its own brand of stochastic resonance as the peaks of the ISIH successively go through a maximum when the noise intensity is increased. Further, the presence of a noise-induced limit cycle introduces a third time scale in the problem. This limit cycle is found to modify qualitatively the phase-locking picture, e.g., by suppressing certain peaks' in the ISIH. Finally, the role of noise and possibly of stochastic resonance (SR) in the neural encoding of sensory information is discussed.

Pellets were pressure-cast and nitrided to form reaction-bonded silicon nitride. Density and binding strength in the green state relate well to rheological behavior and other collodial aspects of the suspensions used, particularly the additive's role and distribution. Density and degree of nitridation in the final state are not importantly affected by the additive's use. Its greatest benefit is to modify the binding strength in the green state. The mode by which this small molecule affects the processing of silicon consists of adsorption, combined with an increased electrostatic interparticle repulsion which increases the suspension viscosity and that of undried pellets. Although the improved binding strength is accompanied by decreased green and nitrided densities, high degrees of conversion to silicon nitride are still achieved.

ION TRAJECTORIES AND DETECTOR PERFORMANCE SO JOURNAL OF THE AMERICAN SOCIETY FOR MASS SPECTROMETRY LA English DT Article ID ATOMIC EMISSION-SPECTROMETRY; ULTRASONIC NEBULIZER; ARGON PLASMA; INTERFERENCES AB A new inductively coupled plasma mass spectrometer (ICP-MS) with four stages of differential pumping is described. The relatively large sampling orifice (1.31-mm dia.) improves signals for metal ions and resists plugging from deposited solids. A new ion lens is described that deflects ions off center and then back on center into the differential pumping orifice; there is no photon stop in the center of the beam. Calculations of ion trajectories using SIMION show that only those ions that leave the skimmer on center are transmitted, whereas most other lenses used in ICP-MS transmit only ions that leave the skimmer off axis. The performance of a Channeltron electron multiplier is compared to that of a Daly detector. Both detectors yield similar sensitivities of approximately 10(6) counts s-1 per ppm and detection limits of approximately 1 pptr. The background with a Channeltron electron multiplier is only 0.4 counts s-1 and is only slightly higher than the dark current count rate. Presumably the offset ion lens used in the present work efficiently screens the detector from photons emitted by the plasma. The background with the Daly detector is 4 counts s-1, which represents a substantial improvement over the background obtained in pervious use of the Daly detector with ICP-MS.

POLYATOMIC ION INTERFERENCES AND MATRIX EFFECTS SO JOURNAL OF THE AMERICAN SOCIETY FOR MASS SPECTROMETRY LA English DT Article ID CONCOMITANT ELEMENTS; ARGON PLASMA; DISSOCIATION; AEROSOL; ANALYTE; SIGNALS AB A new inductively coupled plasma mass spectrometer with an enlarged sampling orifice (1.31-mm dia.) and an offset ion lens yields very low levels of many troublesome polyatomic ions such as ArO+, ArN+, Ar2+, ClO+, and ArCl+. The signals from refractory metal oxide ions are approximately 1% of the corresponding metal ion signals, which is typical of most ICP-MS devices. Grounding the first electrode of the ion lens greatly reduces the severity of matrix effects to less than or similar to 20% loss in signal for Co+, Y+, or Cs+ in the presence of 10 mM Sr, Tm, or Pb. This latter lens setting causes only a modest loss (30%) in sensitivity for analyte elements compared to the best sensitivity obtainable by biasing the first lens. Alternatively, matrix effects can also be mitigated by readjusting the voltage applied to the first lens with the matrix present.

Uniaxial tensile tests were conducted over ranges of constant stresses and constant stress rates. Correlation of stress-life relations between static and dynamic fatigue results was evaluated and failure modes were determined as functions of temperature, stress and stress rate. At 1150-degrees-C the static and dynamic fatigue failures were controlled by a slow crack growth mechanism for all stresses and stress rates. Creep rupture was the dominant failure mechanism in static loading at 1260 and 1370-degrees-C. A transition in the dominant failure mechanism in dynamic fatigue at 1260 and 1370-degrees-C occurred at a stress rate of 10(-2) MPals. Slow crack growth was the dominant failure mechanism with stress rates >10(-2) MPa/s while creep rupture was the governing mechanism for the failure at stress rates less-than-or-equal-to 10(-2) MPa/s.

New structural observations, together with K-Ar and Ar-40/Ar-39 geochronology data from a transect of the Chamo basin-Amaro horst Galana basin, show that basins are bounded by faults with steep dips at the surface, and the stratal dips of Eocene -Recent volcanic and sedimentary units are generally less than 20-degrees. Little or no extension accompanied the extrusion of a 0.5 to 1 km thick sequence of transitional tholeiitic flood basalts between 45 and 35 Ma. Stratigraphical correlations with basins to the north and southwest suggest that felsic eruption(s) at c. 37 Ma blanketed much of the southern Ethiopian plateau region with a felsic tuff unit. A second, less widespread, episode of alkali basalt and trachyte volcanism occurred between 18 and 11 Ma, and Recent alkali basalt volcanism occurs within the Chamo basin. The attitude, distribution, and diversity of Neogene-Recent volcanic and sedimentary strata within the Chamo and Galana basins indicate that crustal extension, basin subsidence, and rift flank uplift began during or after the second flood-basalt phase. Based on cross-sectional reconstruction to the top of the Oligocene tuff, we estimate a minimum of 12 km crustal extension (beta almost-equal-to 1.12), and infer that maximum extension across the southern Ethiopian rift is less than 25 km. Extension is primarily accommodated by slip along the border faults bounding the asymmetric basins, with small amounts of extension occurring within the hanging walls. Crude estimates of original basalt layer thickness prior to erosion in the Amaro region suggest that roughly comparable volumes of basaltic material erupted during the two episodes of flood-basalt magmatism (45-35 Ma and 18-11 Ma). The small amounts of lithospheric extension and the large volumes of magma estimated in this study of the southern Main Ethiopian rift suggest a very hot plume and/or efficient thinning of the mantle lithosphere from below by mantle plume processes during the two discrete episodes of flood-basalt volcanism.

For excitation energies in the range 25-45 meV, a scan at fixed energy yields a single peak with a large q-width centered on the antiferromagnetic wave vector, (pi, pi), in agreement with the work of Rossat-Mignod and coworkers. However, in contrast to the results of the latter group, we have not observed, despite significant effort, any q-dependent magnetic scattering in either crystal at energies below approximately 20 meV, even at temperatures far above T(c).

Copas has studied two forms of robust estimator: a robust-resistant estimate of Pregibon and an estimate based on a misclassification model. He concluded that robust-resistant estimates are much more biased in small samples than the usual logistic estimate is and recommends a bias-corrected version of the misclassification estimate. We show that there are other versions of robust-resistant estimates which have bias often approximately the same as and sometimes even less than the logistic estimate; these estimates belong to the Mallows class. In addition, the corrected misclassification estimate is inconsistent at the logistic model; we develop a simple consistent modification. The modified estimate is a member of the Mallows class but, unlike most robust estimates, it has an interpretable tuning constant. The results are illustrated on data sets featuring different kinds of outliers. C1 LOS ALAMOS NATL LAB,LOS ALAMOS,NM 87544.

Previously, we have observed changes in adult testosterone metabolism and in cytochrome P-450 (P-450) mRNA levels in animals neonatally exposed to phenobarbital (PB) or diethylstilbestrol (DES). In order to test for other enzyme alterations, we used Western blot procedures for specific P450s to analyze hepatic microsomes from adult rats (24 wk old) that had been exposed neonatally to DES, PB, 7,12-dimethylbenz[a]anthracene (DMBA), or pregnenolone 16alpha-carbonitrile (PCN). The most striking effects were observed in the DES-treated males: P-4502C6 and an immunologically similar protein were increased 60 and 90%, respectively, relative to control values, but P-4503A2 was decreased by 44%. No changes were observed in the DES-treated males in levels of P-4502E1, P-4502B, or the male-specific P-4502C13. Adult males neonatally treated with PB had 150% increase in levels of anti-P4502B-reactive protein without significant changes in the other enzymes. The DES- and DMBA-treated females had increased levels of the female-specific P-4502C12 of 38 and 48%, respectively, but no other observed alterations. The results confirm that neonatal exposure to DES or PB can cause alterations in adult hepatic cytochrome P-450 levels but show that these chemicals act on different enzymes. Neonatal DMBA resulted in changes in adult females similar to those produced by the synthetic estrogen DES, but did so at about two-thirds lower dose.

The arachidic acid [CH3(CH2)19COOH] organized molecular assemblies (OMAs) were self-assembled on native oxide grown on freshly prepared 200 nm thick aluminum films on single crystal silicon wafers. XPS spectra were acquired as a function of evaporated copper thickness. Charging shifts of up to 0.84 eV were observed for the C(1s), O(1s), and Cu(2p) photoemission lines during evaporation of up to 4.0 nm of copper. The thickness of the organized molecular assemblies (OMA) is approximately 2.7 nm on the native oxide surface, yielding a total thickness for the oxide/OMA stack of 6-7 nm.

The metal contacts fabricated by sequential vapor deposition were capped with an Al2O3 thin film to form a closed system when subjected to a 420-degrees-C anneal for 3 min. For an as-deposited specimen, the Zn layer was found to react with the two adjacent Au layers and the reaction products were three room-temperature phases of Au3Zn. One of these phases is identified for the first time and its structure is characterized. Upon annealing, these phases remained stable and no interfacial reaction between the metal contact and GaAs was observed, as opposed to an uncapped contact. The interface between the annealed contact and GaAs exhibited the same degree of uniformity and planarity as that of the as-deposited specimen. This study demonstrates that the formation of metallic protrusions into GaAs, as commonly found in an uncapped contact, is not necessary for the transition from rectifying to ohmic behavior of the contact.

Representation of data by ln f(A) = ln f-degrees-A - k(A)'m(A)2 + k(A)''m(A)2, with k(A)' and k(A)'' adjustable parameters expected to depend on both alcohol and electrolyte, was investigated. Plots of ln f(A) vs m(A) were found to be linear within experimental error up to saturation value of m(A) in all cases investigated; i.e., the k(A)''m(A)2 contributed negligibly in all cases and concentrations investigated and could be omitted. Semiquantitative models, based on the principle of independent surface action (for water-alcohol interactions) and dependence of electrolyte activities on dielectric constant, were developed and found to provide reasonable qualitative and semiquantitative interpretation of parameter trends and basis for semiquantitative estimation of parameters for other similar systems. In electrosorption studies involving measurement of the dependence of interfacial tension on organic solute concentration at fixed electrolyte concentration and fixed polarization with respect to a fixed reference electrode (e.g., a saturated calomel electrode), the activity coefficients of both alcohol and electrolyte will change as the organic solute concentration changes. Bases for calculating these changes and their effect on the estimation of organic solute surface excess are given and discussed. C1 IOWA STATE UNIV SCI & TECHNOL,AMES LAB,DOE,AMES,IA 50011.

The study was motivated by the observation that the one-electron reductive desorption of long-chain n-alkanethiolates by linear sweep voltammetry generally exhibits a single well-defined wave,1 while that of ME/Au produces two waves. The relative magnitudes of the waves for ME/Au are dependent on the extent of exposure to the laboratory ambient. Electrochemical oxidation of ME/Au shows that three oxidative processes occur sequentially. In the first process, ME/Au is catalytically oxidized by a four-electron process to a sulfidoacetic acid monolayer (adsorbed mercaptoacetic acid, MAA/Au). In the second process, the electrogenerated MAA/Au undergoes C-S bond cleavage, which gives rise to the second reductive desorption wave. In this case, as the extent of oxidation increases, a third desorption wave is also produced as a result of gradual formation of adsorbed polysulfur species. In the third oxidative process, the remaining sulfur monolayer is oxidatively desorbed from the surface. Our results, coupled with earlier literature reports,1a,2 suggest that electrochemical oxidation of thiolates on gold is a multipath process with the favored path dependent on the reaction conditions and the chemical composition of the thiolate. The spontaneous oxidation of ME/Au may proceed via the same path as the electrochemical oxidation (ME/Au to MAA/Au to S/Au), or adsorption of thiolate may activate the C-S bond, leading to direct conversion from ME/Au to S/Au.

The model includes a straightforward treatment of the controlling kinetics, an exact solution for energy extraction, and an approximation to amplified spontaneous emission losses; it can be easily programmed to run on personal computers. The inclusion of the controlling basic physics for KrF lasers makes the model ideally suited for the many calculations that are necessary to optimize the design of a specific amplifier. The basic parameters determined in the model are compared to experimental data wherever possible, and the large amplifier performance predictions are compared to the results from the most sophisticated kinetics and a 3-D extraction model that includes a full treatment of losses due to amplified spontaneous emission.

Nova is the primary U.S. facility employed in the study of the X-ray-driven (indirect drive) approach to ICF. Nova's principal objective is to demonstrate that laser-driven hohlraums can achieve the conditions of driver-target coupling efficiency, driver irradiation symmetry, driver pulseshaping, target preheat, and hydrodynamic stability required by hot-spot ignition and fuel compression to realize a fusion gain. The LLNL ICF Program believes that the next major step in the national ICF Program is the demonstration of ignition and moderate gain (G less-than-or-equal-to 10). Recent theoretical and experimental results show that the ignition drive energy threshold can be reduced significantly by operating indirectly driven targets at radiation temperatures approximately 1.3-1.6 times higher (thereby achieving higher implosion velocity) than originally proposed for the Laboratory Microfusion Facility (LMF). (Temperatures of approximately 1.3 times higher have already been demonstrated on Nova.) Specifically, it should be possible to demonstrate ignition and propagating with burn about 1-2 MJ of laser energy as against the 5-10 MJ necessary for the high-yield LMF. LLNL proposes to upgrade the existing Nova facility to 1-2 MJ (2- to 4-ns pulses) and demonstrate ignition and propagating burn to moderate gain with appropriately scaled hydrodynamic equivalents of high-yield targets. Once moderate gain has been demonstrated at 1-2.0 MJ on the Nova Upgrade, investigations into improving, by about 50%, the coupling efficiency between the driver and the capsule could provide gains >20 at about 1 MJ or less. A database for gain below 1-MJ driver energies could lead to a low-capital-cost Engineering Test Facility (ETF) for a first inertial fusion energy engineering reactor. Because the capital cost for both the target chamber and the driver scale with size, there is the opportunity to realize large savings by lowering the required driver energy necessary to demonstrate the technology for a first demonstration power plant. A target gain, G approximately 25, at a driver energy, E(D) approximately 0.75 MJ, would be self-sustaining for a driver efficiency of approximately 10% and a thermal-to-electric conversion efficiency of approximately 33% and at 12 Hz would generate approximately 10 MW of gross electric power. Although the cost of electricity would be high, the combination of low capital cost and early demonstration of reactor technology would be an attractive step in the development of inertial fusion energy.

AURORA is the first integrated system for demonstrating the capability of a KrF laser to perform target physics experiments for inertial confinement fusion (ICF) and is currently configured as a 5-kJ, 5-ns, 96-beam device. Both laser physics and ICF target physics experiments have been performed over the last year. Of the four major amplifiers in the AURORA laser system, one performed better than expected, one performed about as expected, and two performed below expectations. The causes of the variability in the amplifier performance are now well enough understood that this information can be used to improve the detailed design of the NIKE laser currently under construction at the Naval Research Laboratory. High-dynamic-range pulse shapes have been propagated with minimal distortion through the AURORA amplifier chain, verifying theoretical predictions. Target physics experiments have been performed with intensities greater than 100 TW/cm2, pulse lengths ranging from 2-7 ns, and spot-size diameters from 500-1100 mum. The analysis of this first-generation kJ-class KrF laser target physics facility identified the strengths and weaknesses of KrF lasers for ICF applications. Detailed measurements of amplifier performance led to a better understanding of issues for KrF laser-fusion systems, and design studies for future KrF lasers for ICF applications incorporate improvements based in part on AURORA experience.

The next opportunity to exercise these tools is with the design of the second-generation NIKE system under construction at the Naval Research Laboratory with the collaboration of Los Alamos National Laboratory. Major issues include laser physics (energy extraction in large modules with amplified spontaneous emission) and diode performance and efficiency. Low cost is increasingly important for larger future KrF single-pulse systems (low cost and high efficiency is important for larger repetitively pulsed applications such as electric power production). In this article, we present our approach to amplifier scaling and discuss the more important design considerations for large single-pulse KrF amplifiers. We point out where improvements in the fundamental database for KrF amplifiers could lead to increased confidence in performance predictions for large amplifiers and address the currently unresolved issues of anomalous absorption near line center and the possibility of diode instabilities for low-impedance designs. Los Alamos has applied these amplifier design tools to the conceptual design of a 100-kJ Laser Target Test Facility and a 3-MJ Laboratory Microfusion Facility.

The noteworthy feature of this model is its ability to make predictions about ionization in ultrastrong fields of multielectron systems for realistic pulse durations of thousands of atomic periods and frequencies substantially lower than the orbital frequency in a three-dimensional setting. In this paper we concentrate on the effects of electron-electron correlations during the process of multiphoton ionization of a helium atom. Correlations between the two electrons are manifested in energy spectra of the ionized electrons, as well as in their angular distributions. C1 [Lerner, P. B.; LaGattuta, K.; Cohen, J.

An ansatz is made in which the relative motion of the two electrons is treated classically and the motion of their center of mass relative to the nucleus quantum mechanically. The quantum mechanical problem is solved on a numerical grid in time and two spatial dimensions, where the center-of-mass motion is constrained to lie in a plane. Numerical results are presented which are interpreted as representing a two-electron transition from the ground state to a doubly excited state.

The dynamics of above-threshold dissociation (ATD) is investigated over a wide range of green and infrared intensities and compared to a dressed-state model. The second situation arises when strong-field neutral dissociation is followed by ionization of the atomic fragments. This study results in a direct measure of the atomic fragment's ac Stark shift by observing the intensity-dependent shifts in the electron or nuclear fragment kinetic energy.

Ionization rates for linear polarized light are extracted from the time evolution of the ground state on a 2d cylindrical coordinate lattice, while rates for circular polarized light are extracted from calculations on a 3d Cartesian coordinate lattice. We confirm LaGattuta's previous results, which rind that the ionization rates for the two different polarizations are nearly equal for intensities a few times 10(14) W/cm(2); these results are in sharp contrast to the perturbation theory prediction of a factor of 10 difference.

The results show that the internal dynamics of the polymer crystal is such that rapid relaxation occurs, providing for a large amount of structural reversibility and making it possible to perform nondestructive AFM experiments. However, surface and/or AFM tip defects or contaminants (such as those which can be induced by polar molecules adsorbed on the surface), can result in significant perturbations in the AFM images produced, causing large and sharp structures to appear on the surface topology. A rationale of the mechanisms responsible for the image distortions is presented, and a relationship to defects observed in AFM and STM experiments is given.

Although the activities of genes encoding the quantitatively major types of collagen are fairly well characterized, functions of the many minor types of collagen remain a matter of speculation. As a first step toward a functional analysis of type XI collagen, a member of this class of poorly understand ''minor'' collagen proteins which is expressed primarily in hyaline cartilage, we have used human probes for the gene encoding the protein's alpha2-subunit (COL11A2) to isolate and map homologous murine DNA sequences. Our results demonstrate that Col11a-2 is embedded within the major histocompatibility complex (MHC), within 8.4 kb of the class II pseudogene locus, Pb, and confirm that human and murine alpha2(XI) collagen genes are located in very similar genomic environments. The conserved location of these genes raises the possibility that type XI collagen genes may contribute to one or more of the diverse hereditary disorders known to be linked to the MHC in mouse and human.

Both loci were found to map to the subregion of the Mod-2-sh-1 interval that contains the eed (embryonic ectoderm development) locus. eed has been defined by the inability of embryos homozygous for certain c deletions to develop beyond the early stages of gastrulation. Evidence for at least two loci necessary for normal prenatal development, rather than one locus, that map within the eed interval came from the observation that two prenatally lethal mutations, 3354SB [1(7)5Rn 3354SB] and 4234SB [1(7)6Rn 4234SB], could complement each other in trans, but could not each be complemented individually by c deletions known to include the eed locus. A somewhat leaky allele of 1(7)5Rn [1(7)5Rn1989SB] was also recovered, in which hemizygotes are often stillborn and homozygotes exhibit variable fitness and survival. The mapping of the loci defined by these mutations is likely to be useful for genetic, molecular, and phenotypic characterization of the eed region, and mutations at either locus (or both loci) may contribute to the eed phenotype.

Two thousand thirteen randomly chosen recombinants, with an average insert size of 35 kb and representing 2.35% of the haploid genome of P. leucopus, were screened with probes representing microsatellites, tandem repeats, and transposable elements. Of the four dinucleotides, (GT)n was present in 87% of the clones, (CT)n was present in 59% of the clones, and (AT)n and (GC)n each was represented in our sample by a single clone (0.05%). (TCC)n was present in 8% of the clones. Of the tandem repeats, the 28S ribosomal probe and the (TTAGGG)n telomere probe were not represented in the library, whereas a heterochromatic fragment was present in 9% of the clones. A transposable element, mys, was estimated to occur in 4700 copies, whereas a long interspersed element (LINE) was estimated to occur in about 41,000 copies per haploid genome. LINE and mys occurred together in the same clones more frequently than expected on the basis of chance. Hybridizing the library to genomic DNA from P. leucopus, Reithrodontomys fulvescens, Mus musculus, and human produced general agreement between phylogenetic relatedness and intensity of hybridization. However, dinucleotide repeats appeared to account for a disproportionately high number of positive clones in the more distantly related taxa.

For comparison, specimens were examined from two pristine reference sites near the impacted Tennessee and Mississippi sites. Significantly more strand-breaks were found in DNA isolated from liver tissue of redbreast sunfish (Lepomis auritus) from contaminated creeks than in DNA from sunfish from two pristine creeks. Hemoglobin concentration (C(Hb)) and mean corpuscular hemoglobin concentration (MCHC) were significantly higher in both male and female sunfish from the pristine creeks. Furthermore, the liver somatic index (LSI) of sunfish from contaminated creeks was higher than that of specimens from reference sites. In adult male, female, and juvenile hardhead catfish (Arius felis) from suspected contaminated sites in the Mississippi Sound, high LSI and lowered C(Hb) and MCHC were found A higher percentage of double-stranded DNA was measured in specimens from the pristine reference sites. Individual differences in responses of the biological markers, however, were large, as reflected by high standard deviations. The biological responses measured were obviously valuable to indicate differences in the environmental quality expressed in molecular and physiological terms.

Of seven separate legs, six official legs and on unofficial leg on the homeward journey, four were devoted primarily to physical oceanographic measurements. Basin-wide surveys of bottom sediments and biological variables were also undertaken but those results are not covered here. A variety of physical oceanographic observations were taken: 1. over 500 CTD casts were made; 2. seven current meter moorings were deployed and six were recovered yielding 11 quality current meter records at different depths; 3. 36 drifting buoys with Argos positioning were deployed; and 4. continuous shipboard measurements of meteorological and oceanographic variables were recorded. The expedition data base continues to grow as new data from coastal meteorological and tide stations are added. The measurements are reviewed from the experimental point of view. Data accuracy, resolution, and precision are discussed and quality assurance of the measurements is reviewed. The complete data set covers the important seasonal transition from mid-winter to early summer. During this period of time, solar heating created an intense thermocline which decoupled the surface mixed layer from the interior water. The data are reviewed in the light of prior measurements and recent modelling results. RP BROOKHAVEN NATL LAB, UPTON, NY 11973 USA.

The models are used to compute the flows in the Gulf driven by density gradient using the two sets of data collected on Legs 1 and 6 of the Mt Mitchell cruise. The two flows are compared with one another, with the result of a similar computation using the 1977 Atlantis II data and with computations of the flow driven by the prevailing wind. The combined residual flow due to wind and density gradient is found and compared to empirical estimates of the residual flow derived from ship-drift reports. The accuracy of the models is tested using the computed and observed water velocities at some of the current meters deployed during the cruise. C1 BROOKHAVEN NATL LAB, UPTON, NY 11973 USA.

Accordingly, the development programme for this class of alloys has included an investigation of the corrosion properties in mixed oxidant (H2S-H-2-H2O) environments. Corrosion studies were initially directed at Fe3Al and FeAl, including effects of third element additions such as Cr, Nb, Mo, Zr and Y. Iron-aluminium alloys with lower aluminium concentrations (between 16 and 22 atom%) were next investigated to establish the minimum aluminium concentration needed to resist sulfidation and oxidation. The results have shown that alloys containing greater than or equal to 18% Al are uniquely resistant to H2S-containing environments at 800 degrees C. Chromium adversely affected the corrosion resistance in this mixed gas environment, although this effect was partially offset by the addition of molybdenum. Zirconium and yttrium had no significant effect on the corrosion rate under the same temperature and environmental conditions. Metallographic and chemical analyses of the corrosion product scales and underlying alloy were performed to determine the roles of the respective metallic elements in the corrosion process in H2S-H-2-H2O. These results, together with weight change determinations, are discussed in terms of the apparent corrosion mechanisms and optimization of alloy composition for exposure to gasifier environments.

Investigations focused on three areas: metallography done remotely in a reactor tank, metallography performed in hot cells on material removed from reactor tank walls, and metallography on laboratory samples as part of an effort to develop repair methods that do not produce helium-embrittlement cracking. Light metallography, used in all three areas, showed the intergranular nature of the cracks and was used to quantify the extent of cracking. Scanning electron microscopy was used to support crack analysis and to show the dimple structure arising on fracture surfaces caused by helium-induced cavity formation along grain boundaries. Transmission electron microscopy showed that helium bubbles form along incoherent boundaries and that a bubble-free zone exists near such boundaries. The impact of these findings on the extent of cracking and on the nature of the embrittlement mechanism is discussed.

Under this program, funding is provided through the ISU Center for Advanced Technology Development (CATD) to develop laboratory test sets into salable instruments and test tube chemicals into material producible by the carload. Industry then contracts for rights to produce the entities. Under CATD funding, the Center for Nondestructive Evaluation (CNDE) has carried out a program to develop an automatic ultrasonic instrument for nondestructively predicting drawability of sheet metal. Based on an ultrasonic test set assembled and tested in CNDE using EMAT technology (electromagnetic acoustic transducers), the instrument measures the travel times of S0-mode Lamb waves at 0, 45, and 90 degrees to the rolling direction in sheet metal, computes velocity and Young's modulus in each direction, and then computes parameters used in physical metallurgy to express rolling texture and to predict drawability. The development of this instrument was carried on by a team put together by the CNDE from personnel in CNDE, Ames Laboratory, the Small Business Development Center at ISU, Magnasonics, Inc., and other suppliers. Cooperative work was carried on with the National Institute of Standards and Technology at Boulder, CO. The ISU program consisted of four phases, marketing, design, fabrication and test, and marketing II; the approach was self-consistent with the CATD mission to commercialize the earlier research. Details of the instrument, its development, and its performance will be given. C1 IOWA STATE UNIV SCI & TECHNOL,DOE,AMES LAB,AMES,IA 50011. MAGNASON INC,ALBUQUERQUE,NM 87108.

The first is to describe some simple and robust iterative schemes for nonsymmetric and indefinite elliptic boundary value problems. The schemes are based in the Sobolev space H-1 (OMEGA) and require minimal hypotheses. The second is to develop algorithms utilizing a coarse-grid approximation. This leads to iteration matrices whose eigenvalues lie in the right half of the complex plane. In fact, for symmetric indefinite problems, the iteration is reduced to a well-conditioned symmetric positive definite system which can be solved by conjugate gradient iteration. Applications of the general theory as well as numerical examples are given. C1 AUSTRALIAN NATL UNIV,STAT RES STN,CANBERRA,ACT 2601,AUSTRALIA. BROOKHAVEN NATL LAB,DEPT APPL SCI,UPTON,NY 11973.
