We describe interior point algorithms for a discrete-time linear-quadratic regulator problem with mixed state/control constraints and show how they can be efficiently incorporated into an inexact sequential quadratic programming algorithm for nonlinear problems. The key to the efficiency of the interior-point method is the narrow-banded structure of the coefficient matrix which is factorized at each iteration.

Assuming the highly symmetric structure recently proposed for M8C12, geometries are determined in small basis sets for both species. Sc8C12 adopts a closed-shell structure. At the SCF level, the lowest energy configuration for Ti8C12 corresponds to a high-spin ground state with eight unpaired electrons; a dense manifold of low-lying states arises from other spin couplings. Electronic states corresponding to 20-pi-electron structures are calculated to lie at much higher energies at the SCF level. The apparent stability of these species appears to arise from the topology of the metal-carbon cage rather than from any special feature regarding electron count.

The critical energies for fusion and fragmentation as well as details of the energy transfer during the collision process for the bouncing regime are investigated.

PATHWAY ANALYSIS FOR HOMOLOGOUS ORGANIC SPACERS SO JOURNAL OF PHYSICAL CHEMISTRY LA English DT Article ID LONG-RANGE ELECTRON; LOCALIZED MOLECULAR-ORBITALS; TEMPORARY ANION STATES; THROUGH-BOND; DISTANCE DEPENDENCE; ENERGY-TRANSFER; MATRIX-ELEMENTS; TRANSFER RATES; SYSTEMS; PROTEINS AB Ab initio calculations of transfer integrals (T(DA)) for long-range pi- and sigma-type electron transfer through saturated spacers linking donor (D) and acceptor (A) groups in several radical anion and cation systems have been carried out and analyzed in terms of additive superexchange models. The sensitivity of calculated results to orbital basis and wave function type has been carefully examined. The one-electron Koopmans' theorem approach, based on the neutral triplet diradical parent state and employing the split valence 3-21 G basis, provides generally reliable results. The minimal STO-3G basis is quantitatively useful in some cases, where it facilitates a compact perturbative analysis of the coupling in terms of competing pathways. For trans alkyl spacers containing one to seven CC bonds, reasonably good global exponential fits are obtained for fall-off of T(DA) with D-A separation even though the relative importance of different pathway types (hole, electron, and hybrid) changes markedly over the range of spacers. The calculated decay coefficients beta(r) cover a range of approximately 0.5-0.9 angstrom-1, being systematically greater for radical anions than for cations (by a factor of 1. 1- 1.7, depending on wavefunction type), consistent with similar findings by Jordan and Paddon-Row for radical cation and anion systems involving norbornyl spacer groups. The behavior of calculated transfer integrals for spacers composed of bicyclo[1.1.1]pentane (bcp) and bicyclo[2.2.2]octane (bco) units is complex, including cases of nonmonotonic variation with number of units (1, 2, or 3), and global exponential fits were possible only for pi-transfer through the bcp spacers. The calculated lower limit Of beta(r) (approximately 1.6 angstrom-1, based on the first two members of the series) for pi transfer through the bco spacers is consistent with inferences from experimental fluorescence quenching data. The decay found in the intramolecular systems is similar to that (beta(r) approximately 0.9 angstrom-1) exhibited by non-covalently-linked spacers of methane molecules in van der Waals contact. While nearest-neighbor (NN) McConnell-type pathways based on local bonding or antibonding orbitals are found to be unimportant, a McConnell-type model was recovered at a more coarse-grained level based on larger spacer units and representable in a matrix form isomorphic to the standard scalar McConnell expression.

Neutrons corresponding to excitations of 465 +/- 23, 737 +/- 20, 1017 +/- 34, 1251 +/- 20, 1432 +/- 23 and 1692 +/- 25 keV are observed. It is shown that the observables are reasonably described with a conventional optical-statistical model having energy-dependent geometric parameters. These model parameters are consistent with systematic behaviours previously reported from this laboratory. The energy dependencies are alleviated when the model is extended to include the contributions of the dispersion relationship. There is no indication of anomalous behaviour of the neutron interaction with Sc-45, five nucleons from the doubly closed shell at Ca-40.

Thus the (extended) particle distribution function appears as one of the fields to be freely varied in the action. The Hamiltonian structures of the Vlasov-Maxwell equations and of the reduced systems associated with small-amplitude perturbation calculations are easily obtained. Previous results for the linearized Vlasov-Maxwell system are generalized. We find the Hermitian structure also when the background is time-dependent, and furthermore we may now also include the case of non-Hamiltonian perturbations within the Hamiltonian-Hermitian context. The action principle for the Vlasov-Maxwell system appears to be suitable for the derivation of reduced dynamical equations by expanding the action in various small parameters.

(1990), J. Biol. Chem. 265, 3642-36471. The equivalent position is occupied by lysyl or arginyl residues in the PRK from both prokaryotic and eukaryotic sources, suggesting a requirement for a basic residue at this location. To examine this possibility, we have replaced Lys68 of the spinach enzyme with arginyl, glutaminyl, alanyl, or glutamyl residues by site-directed mutagenesis. All of the mutant enzymes retain substantial kinase activity; and even in the case of the radical substitution by glutamate, the K(m) values for ATP and ribulose 5-phosphate are not perturbed significantly. Glutamate at position-68 may destabilize tertiary structure, because the yield of this mutant protein from transformed E. coli is quite low compared to that of the other proteins in this series. Despite the active-site proximity of Lys68, our results show that this residue does not play a key role in catalysis or substrate binding.

The equation consists of a virial expansion truncated after the fourth virial coefficient and a closed-form term approximating higher coefficients. Mixing rules are based on the composition dependence of virial coefficients, which is known from statistical mechanics. The equation accurately represents vapor-liquid and gas-gas equilibria for the Ar + H2O and Xe + H2O systems over wide ranges of pressure and temperature using two binary parameters. With the binary parameters determined from phase equilibrium data, the equation accurately predicts apparent molar volumes V(phi) in the near-critical and far-from-critical regions. Apart from reproducing experimental V(phi) data, the equation reveals remarkable maxima of V(phi) as a function of pressure and temperature in the near-critical region. The implications of this equation with respect to the Ar-H2O potential are discussed via the second virial coefficient. C1 UNIV CALIF BERKELEY,DEPT CHEM,BERKELEY,CA 94720.

In both of these applications, the ambiguity function is usually evaluated repeatedly over a region of interest for a specific acoustic array. When either the region or the array is large, computational efficiency is an issue. In this paper, two algorithms are presented for efficiently evaluating the spatial ambiguity function over weakly range-dependent regions utilizing an adiabatic normal mode signal model. The algorithms are referred to as the direct method and the indirect method. The direct method involves a recursive update in range of the so-called replicant vector. The computational complexity of the direct method for each range step is proportional to the product of the number of array sensors and the number of modes. In contrast, the indirect method recursively updates the entire ambiguity function and has an incremental computational complexity proportional to the number of modes squared. Thus, for low-frequency operation with a large array, the indirect method is more efficient. Computational results are presented in which the relative efficiency of the two algorithms is compared.

In general, Al2O3 additions increase the glass transition temperature, decrease thermal expansion, and improve aqueous durability. However, the composition/property relationships are strongly influenced by relative cation ratios and thus the overall O/P ratio. The nature of these glasses undergoes significant transformations at both the pyrophosphate (O/P = 3.5) and the orthophosphate (O/P = 4.0) compositions, producing significant changes in the property behavior. Spectroscopic analyses of glass structure, described in part II of this report, reveal that changes in Al coordination coincide with the breaks in the property behavior.

In general, the glass properties (evaluated in part I) are most sensitive to changes in Al coordination. Al-27 MAS NMR spectra reveal that octahedrally coordinated Al is most abundant in glasses with O/P ratios less than 3.5, the pyrophosphate structural limit. Tetrahedrally coordinated Al is most abundant in glasses with O/P greater than 3.5. Decreasing Al(OP)6/Al(OP)4 ratio generally correlates with decreasing glass transition temperature and refractive index. The compositional dependence of glass structure and properties can be qualitatively understood using a crystal chemical model based on oxygen charge balancing by the different Al and P moieties.

The deposition conditions were chosen to assure thermalization of the sputtered flux, which proved to be necessary in order to obtain a homogeneous distribution of Si and P in the films. Optical absorption and ac impedance measurements showed that glass-in-glass phase separation occurred in a large SiO2-rich domain of the composition diagram. In contrast to bulk glasses, all of the Li2O-SiO2 films were phase-separated, including those with lithia contents larger than lithium disilicate. High-performance liquid chromatography measurements revealed that, analogous to bulk glasses, the addition of SiO2 to Li2O-P2O5 compositions reduced the number of phosphate anion dimers, trimers, and higher anion polymers in the films through the formation of -Si-O-P- bonds. However, in contrast to bulk glasses, the distribution of phosphate anion polymers followed closely the Flory distribution, with the fraction of anion polymers decreasing monotonically with increasing chain length.

In each case a distinctive reaction rate for the first H/D exchange was observed, and exchanges of up to three deuterium atoms occurred with characteristic ion abundances that could be used to differentiate the isomers. O6-Methyl guanine, for example, showed only one slow H/D exchange with D2O, whereas 1-methyl guanine exchanged two hydrogen atoms at a significantly faster rate. On comparison of the possible resonance structures of each protonated isomer with the experimental information about the number and rate of H/D exchanges observed, a reaction mechanism involving a concerted proton abstraction-deuterium cation donation was proposed.

The black film formed on Cu(P) in Cl--containing solutions was found to resemble a porous sponge composed of CuCl but laden with concentrated CuSO4 solution. The gravimetric experiments show that the difference between the buoyancy-corrected measured mass change and the charge-equivalent mass change has two components: a reversible part that comes and goes as the current is turned on and off, and an irreversible part that remains on the surface and increases in mass with time as dissolution proceeds. The reversible part of the mass change arises from the weight of the diffusion layer. The irreversible part results from the anodic film, which increases linearly in mass with charge density but at a rate that is independent of current density. P inhibits the disproportionation of Cu+1 that results in the poorly adherent anodic film that forms on OFHC Cu anodes. C1 BROOKHAVEN NATL LAB,DIV APPL SCI,UPTON,NY 11973.

Specifically, we have determined the amount of water taken up by membranes immersed in liquid water and by membranes exposed to water vapor of variable water activity. Transport parameters measured are the diffusion coefficient and relaxation time of water in the membrane and the protonic conductivity of the membrane as functions of membrane water content. The ratio of water molecules carried across the membrane per proton transported, the electro-osmotic drag coefficient, also was determined for a limited number of membrane water contents. The drag coefficient is contrasted with the experimentally determined net water transport across an operating PEM fuel cell.

Optical and electrochemical characterization showed strong electrochromic activity under certain deposition conditions. X-ray diffraction and infrared absorption measurements indicate that the films are polycrystalline NiO and that the bulk crystal structure does not change upon oxidation and reduction. Electronic conduction in the films and charge storage at the NiO\electrolyte interface were studied by dc resistance and ac impedance measurements. The infrared measurements and x-ray photoelectron spectroscopy were used to characterize changes in surface composition. We interpret the experimental results as follows: electrochromic activity requires a porous, granular NiO film with excess oxygen at the grain surfaces. The film is reduced by the transfer of protons from water molecules to oxygen ions at the solid surface, and the film is oxidized by the transfer of protons from the solid surface to hydroxyl ions in solution.

The model uses multitemperatures for thermal nonequilibrium. Nonzero chemical affinities are used as a measure of the deviation from chemical equilibrium. Internal energy, enthalpy, entropy, Gibbs and Helmholtz free energies, and the speed of sound are computed for pressures ranging from 0.1 to 100 kPa, and electron translational temperatures ranging from 5000 to 35,000 K. Effects of the changes in pressure, chemical affinity, and temperatures of different energy modes and species on the thermodynamic properties of molecular hydrogen are examined and discussed. It is found that a positive affinity of the recombination reaction or a decrease in plasma pressure will cause ionization to occur at lower temperatures, resulting in higher plasma enthalpy, internal energy, and entropy. Increase of the temperature of a particular energy mode also increases the total energy and entropy of the plasma, but the translational temperatures play a dominant role in the temperature range considered. The speed of sound is changed more by chemical nonequilibrium than by thermal nonequilibrium effects. C1 EG & G IDAHO,IDAHO NATL ENG LAB,IDAHO FALLS,ID 83415.

With proper processing, imogolite tubes may be synthesized and aligned into macroscopic, densely-packed arrays yielding a porous solid exhibiting a high degree of microporosity which is oriented in a single dimension as demonstrated via SEM and TEM. Si-29 MAS NMR indicates that with proper synthesis, essentially pure tube bundles may be obtained with very low concentrations of amorphous (nontubular) impurities as compared to purified natural imogolite. The microporous structure of natural and synthetic imogolite has been investigated by nitrogen adsorption at 77 K as a function of out gassing temperature. For synthetic samples, pore volumes are approximately 0.2 cm3/g and the average pore diameter for the 100% Si sample is approximately 0.7 nm and is approximately 0.9 nm for the 50% Si/50% Ge sample. CO2 and CH4 adsorption at 273 K is measured over the pressure range of 0-800 Torr and uptake is influenced by tube diameter even though the surface area of the two synthetic samples is similar.

EXPERIMENTS ON RECONSTRUCTED BLADES SO MATERIALS CHARACTERIZATION LA English DT Article AB In a recent article [J. D. Verhoeven and A. H. Pendray, Mat. Char. 29:195-212 (1992)] the authors demonstrated that the striking pattern on genuine Damascus blades can be reproduced by forging small crucible solidified steel ingots, but the origin of the cementite particles that form the pattern was not discussed. Experiments are presented here that examine the evolution of the cementite particle formation during the forging process. In addition, a comparison study was done on blades formed from vacuum induction-melted chill cast steels of similar compositions to investigate the role of reduced dendrite spacings. The experiments provide evidence that the cementite particles that produce the bands are formed in the forging process by precipitation from the austenite in planar sheets of clustered particles, with the sheets spaced at a distance corresponding to the primary dendrite spacing inherited from the ingot. The experiments are shown to support the hypothesis that the cluster sheet formation in Damascus steel is a type of carbide banding: The segregated impurity elements of the small ingots are deformed into planar arrays on forging and somehow cause the cementite to nucleate along the planar arrays during the cyclic thermomechanical forging process.

DESTRUCTION AND REFORMATION OF THE PATTERN SO MATERIALS CHARACTERIZATION LA English DT Article AB Two genuine Damascus steel blades and two reconstructed Damascus blades have been austenitized to the point where all of the cementite particles responsible for their Damask pattern were dissolved into the austenite. It is demonstrated that subsequent thermal cycling causes the reprecipitation of cementite particles in the same sheetlike morphology of the original blades, provided that the austenitization temperature is low enough to avoid homogenization of the major impurity elements, Mn, Si, S, and P. The results provide strong support for the hypothesis of Part I [Materials Characterization 30:175-186 (1993)], that the formation of sheets of clustered cementite particles in genuine Damascus blades is a type of carbide banding caused by microsegregated third elements deformed into sheets during the cyclic forging process. Several thermal cycling experiments on reconstructed blade pieces are presented. The experiments support a model in which the third-element additions bias the nucleation of cementite particles into the sheet geometry, followed by enhancement of the sheet morphology by particle coarsening during the thermal cycles.

The latter reduce to Darcy's law when the inertia of the fluid can be neglected, and when the viscosity of the fluid does not enter into the expression for the partial stress for the fluid. A comparison of the two solutions shows that there are conditions when Mixture Theory could predict results that provide a significant departure from those predicted by Darcy's Law. In this paper we delineate the extent of validity of Darcy's law, within the context of a more general theoretical framework. The results of our work indicate that Darcy's law is indeed quite good for low flow rates for a fluid like water. However this is not the case for dense fluids, say oils or effluents, due to the inclusion of inertial effects in the equations of motions. C1 UNIV PITTSBURGH,DEPT MECH ENGN,PITTSBURGH,PA 15261.

In particular, we are concerned with the simple additive multilevel algorithm discussed recently together with J. Xu and the standard V-cycle algorithm with one smoothing step per grid. We shall prove that these algorithms have a uniform reduction per iteration independent of the mesh sizes and number of levels, even on nonconvex domains which do not provide full elliptic regularity. For example, the theory applies to the standard multigrid V-cycle on the L-shaped domain, or a domain with a crack, and yields a uniform convergence rate. We also prove uniform convergence rates for the multigrid V-cycle for problems with nonuniformly refined meshes. Finally, we give a new multigrid approach for problems on domains with curved boundaries and prove a uniform rate of convergence for the corresponding multigrid V-cycle algorithms.

To improve the wear resistance of these commercially important irons, the United States Bureau of Mines and CSIRO Australia are studying their solidification and solid-state transformation kinetics. A ternary Fe-Cr-C iron with 17.8 wt pct (pct) Cr and 3.0 pct C was compared with commercially available irons of similar Cr and C contents with Si contents between 1.6 and 2.2 pct. The irons were solidified and cooled at rates of 0.03 and 0.17 K . s-1 to 873 K. Differential thermal analysis (DTA) showed that Si depresses the eutectic reaction temperature and suggests that is has no effect upon the volume of eutectic carbides formed during solidification. Microprobe analysis revealed that austenite dendrites within the Si alloyed irons cooled at 0.03 and 0.17 K . s-1 had C and Cr contents that were lower than those of dendrites with the ternary alloy cooled at the same cooling rate and a Si alloyed iron that was water quenched from the eutectic temperature. These lower values were shown by image analysis to be the result of both solid-state growth (coarsening) of the eutectic carbides and some secondary carbide formation. Hardness measurements in the as-cast condition and after soaking in liquid nitrogen suggest an increase in the martensite start temperature as the Si content was increased. It is concluded that Si's effect on increasing the size and volume fraction of eutectic carbides and increasing the matrix hardness should lead to improved wear resistance over regular high-chromium white cast irons.

We introduce a novel means of mapping more precisely to c. 20 kb by use of rare restriction sites within vectors bearing cloned sequences that undergo homologous recombination with the genome. We thereby localize and orient genes encoding principal photosynthetic pigments. The relative spacing of loci within a single restriction fragment was determined with even higher resolution, as illustrated for genes required for heterocyst development and nitrogen fixation that were marked with transposons. Small, newly visualized restriction fragments of the chromosome were also mapped. C1 MICHIGAN STATE UNIV,US DOE,PLANT RES LAB,E LANSING,MI 48824.

Thirteen of 27 radiation-induced and one of four spontaneous mutations manifested deletions or rearrangements for the tyrosinase gene. The sizes of four deletions found to break within the tyrosinase gene itself were estimated to be less-than-or-equal-to 36 kb, less-than-or-equal-to 40 kb, approximately 260 kb, and approximately 480 kb. Two homozygous-viable deletions were found to include flanking proviral loci, suggesting that they could be from 1500-2000 kb in length, if not longer. The existence of these very large, homozygous-viable deletions suggests that the one-to-two megabases including and surrounding the c locus harbor no genes essential for normal viablility or fertility, although genes controlling more subtle (or ''nonessential'') phenotypes are likely to be present. These data thus provide some insight into the molecular structure of a number of viable c-locus mutations, whose nature could not be predicted solely on the basis of genetic analysis, as could be done for either lethal or reduced-pigment c mutations.

During the encounter, the spacecraft was deflected into a new orbit, inclined at about 80-degrees to the ecliptic plane, which will ultimately lead Ulysses over the polar regions of the Sun1. Within 1 AU from Jupiter, the onboard dust detector2 recorded periodic bursts of submicrometre dust particles, with durations ranging from several hours to two days, and occurring at approximately monthly intervals (28 +/- 3 days). These particles arrived at Ulysses in collimated streams radiating from close to the line-of-sight direction to Jupiter, suggesting a jovian origin for the periodic bursts. Ulysses also detected a flux of micrometre-sized dust particles moving in high-velocity (greater-than-or-equal-to 26 km s-1) retrograde orbits (opposite to the motion of the planets); we identify these grains as being of interstellar origin.

The effect of initial temperature, pressure, hydrogen concentration, and steam concentration is evaluated for two cases, (1) constant volume and (2) constant initial pressure. For each case, the Adiabatic, Isochoric, Complete Combustion (AICC), Chapman-Jouguet (CJ), and normally reflected CJ pressures are calculated for a range of hydrogen and steam concentrations representative of the entire flammable regime. For detonation loads, pressure profiles and time-histories are also evaluated in one-dimensional Cartesian geometry. The results show that to a first approximation, the AICC and CJ pressures are directly proportional to the initial density. Increasing the hydrogen concentration up to stoichiometric concentrations significantly increases the AICC, CJ, and reflected CJ pressures. For the constant volume case, the AICC, CJ, and reflected CJ pressures increase with increasing hydrogen concentration on the rich side of stoichiometric concentrations. For the constant initial pressure case, the AICC, CJ, and reflected CJ pressures decrease with increasing hydrogen concentration on the rich side of stoichiometric values. The addition of steam decreases the AICC, CJ, and reflected CJ pressures for the constant initial pressure case, but increases them for the constant volume case. For detonations, the pressure time-histories can be normalized with the AICC pressure and the reverberation time for Cartesian geometry.

Neutral particle pressures in the mn of 2-20 mtorr have been measured in this new experiments in L and H mode plasmas in which the neutral beam power was varied and the divertor target location was scanned with respect to the entrance aperture. These pressures exceed the predicted minimum required to provide adequate particle exhaust for controlling the density in H mode discharges when pumping experiments are conducted in the future. The pressure measurements presented here, which were carried out in the absence of a pump, were modelled with the aid of two transport codes: an edge plasma code and a neutrals code. It was found in this modelling process that the divertor flux amplification factor required to explain the measured pressures is of the order of 30 to 40, much higher than the factors used in the modelling of data in the absence of the baffle. This higher flux amplification factor results from increased recycling at the divertor owing to the presence of the baffle. C1 SANDIA NATL LABS,LIVERMORE,CA 94550.

It contains data for all 33509 ASDEX shots. The statistics of disruptions on ASDEX am evaluated for all these shots; in a more detailed analysis, different operation regimes are regarded separately. It is found that after eliminating the most dangerous operation regimes, 17% of all shots end with a disruption. Them is an indication that a well established discharge may be repeated several times at a lower disruption rate (less than 5% for ELMy H modes). The statistics of the flux expulsion at a disruption indicate that a major disruption is characterized by a typical current profile change of DELTAl(i) almost-equal-to -0.37. It is found that about 50% of all disruptions have clear precursors lasting for more than 50 ms, namely locked modes or minor disruptions which, in a future machine, might be used to trigger the application of stabilization or shutdown schemes. From the statistics of the radial and vertical displacements during a disruption the average forces on the vacuum vessel are calculated which, in the case of ASDEX, are not critical, but may be of concern for future large devices.

We describe the storage cell technique as applied in this measurement of elastic and inelastic electron scattering from tensor polarized deuterium. An analysis of electron-beam-induced depolarization of the target was performed and experimental tests were carried out which verify the effect. Other effects causing depolarization of the target are discussed as well as the means by which they are overcome. The effective p(zz) of the target, shown to be stable over 8 months, was 0.57 +/- 0.05; the total target thickness was increased over that of a jet target by a factor of fifteen.

We have studied charge trapping in thick (field) oxide layers on detector wafers by irradiating FOXFET biased strip detectors and MOS test capacitors. Special emphasis was put on studying how a negative bias voltage across the oxide during irradiation affects hole trapping. In addition to FOXFET biased detectors, negatively biased field oxide layers may exist on the n-side of double-sided strip detectors with field plate based n-strip separation. The results indicate that charge trapping occurred both close to the Si-SiO2 interface and in the bulk of the oxide. The charge trapped in the bulk was found to modify the electric field in the oxide in a way that leads to saturation in the amount of charge trapped in the bulk when the flatband/threshold voltage shift equals the voltage applied over the oxide during irradiation. After irradiation only charge trapped close to the interface is annealed by electrons tunneling to the oxide from the n-type bulk. C1 RES INST HIGH ENERGY PHYS,SEFT,HELSINKI,FINLAND.

The number of initiating events in a time t is assumed to follow a Poisson distribution, and a model previously developed is used to describe the ensuing neutron detection, absorption and multiplication. Expressions for the factorial moments of various orders are derived. In particular, the expected value of coincidence pairs is shown to be the sum of the pairs generated within each initiating event and the accidental coincidences between pairs from different initiating events. Due to the Poisson nature of the underlying initiating distribution, the accidental coincidence counts are proportional to the square of the total counts. Statistical parameters including variances of several measurable physical quantities are also derived. RP LU, MS (reprint author), BROOKHAVEN NATL LAB,TECH SUPPORT ORG,UPTON,NY 11973, USA.

SXRF is complementary to other microanalytic techniques, such as PIXE and SIMS, and is advantageous because of its ppm sensitivity, low energy deposition, and ease of quantification. Disadvantages include the difficulty in producing micrometer-sized beams and the relatively large sampling depth (typically, tens of micrometers). Synchrotron source type is an important consideration in designing an X-ray microprobe and optimizing analytical conditions for a particular experiment. Bending magnet sources offer high polarization, reliability and availability. Superconducting wigglers offer higher flux at high energy (excitation of K fluorescence from heavy elements) but access is limited and polarization may be poorer. High energy undulators, such as those being built for the Advanced Photon Source (Argonne), provide very intense, broad band pseudo-monochromatic radiation that can be tuned to the absorption edge of interest. Recent experiments with the XRM on each of these sources are described as well as applications relevant to SXRF-PIXE intercomparisons. C1 BROOKHAVEN NATL LAB,DEPT APPL SCI,UPTON,NY 11973.

The high energy required for these implants is often achieved by implanting multiply charged ions, which inevitably brings in the problem of low-energy ion contamination. The low-energy contamination is difficult to diagnose and detect. Positron annihilation spectroscopy is used to examine the defect distributions in these high energy implants with varying degrees of contamination. C1 EATON CORP,DIV SED,BEVERLY,MA 01915.

For inert gas plasmas such as He, Ne, AT, Kr and Xe, the extractable current density is higher than 1 A/cm2. When diatomic gases, such as H-2, N2 and O2, are used for the discharge, the extracted beam contains almost pure atomic ions. Thus, simple accelerator or plasma processing systems can be constructed without the use of mass analyzing magnets. The same source has also been used to produce steady-state beams of metallic ions.

Tests showed substantial improvements in hardness, wear resistance, oxidation resistance, resistance to chemicals, and electrical conductivity. The magnitude of property changes was strongly dependent upon ion species, energy, dose, and polymer structure. Both hardness and electrical conductivity increased with ion energy and dose. These properties were apparently related to the effectiveness of cross-linking. loon species with a large electronic stopping cross-section are expected to produce more cross-linking. It is believed that the polymer property improvements are commensurate with the extent of cross-linking, which is responsible for the formation of three-dimensionally-connected, carbon-rich, rigid networks.

Nevertheless, searches for neutrino mass continue, largely because the consequences of neutrinos having mass would be quite profound. In particular, the discovery of a non-zero neutrino mass would be a clear indication of physics beyond the current particle-physics standard model. In addition, neutrinos, if they have mass, remain viable candidates for the non-baryonic dark matter known to permeate galaxies. The current status of the experimental efforts searching for neutrino mass will be reviewed. In particular, it will be shown that the most recent tritium beta decay searches for neutrino mass clearly rule out the non-zero neutrino mass result first reported in 1980 by the Institute for Theoretical and Experimental Physics (ITEP) in Moscow. However, a troubling feature of these same recent results is that they all have best fits to neutrino mass squared that are negative. The significance of these negative neutrino mass squared results will be explored. RP LOS ALAMOS NATL LAB, DIV PHYS, LOS ALAMOS, NM 87545 USA.

The number of Ge-71 atoms extracted from 30 tons of gallium in 1990 and 57 tons in 1991 was measured in twelve runs during the period of January 1990 to December 1991. For the 1990 data, we observed the capture rate to be 20 + 15/-20 (stat) +/- 32 (syst) SNU, resulting in a limit of less than 79 SNU (90% CL). This is to be compared with 132 SNU predicted by the Standard Solar Model. The 1991 data, taken with 57 tons of gallium, shows a non zero Ge-71 signal. A final result from the 1990 and 1991 data is still pending completion of studies of possible systematic effects. C1 LOS ALAMOS NATL LAB,LOS ALAMOS,NM 87545. UNIV PENN,PHILADELPHIA,PA 19104.

The target consists of 30.3 t of gallium in the form of 8.13 M aqueous gallium chloride solution (101 t), shielded by almost-equal-to 3300 m water equivalent of standard rock in the Gran Sasso Underground Laboratory (Italy). In nearly one year of operation, 14 measurements of the production rate of Ge-71 were carried out to give, after corrections for side reactions and other backgrounds, an average value of 83+/-19 (stat.)+/-8 (syst.) SNU (1sigma) due to solar neutrinos. This conclusion constitutes the first observation of solar pp neutrinos. Our result is consistent with the presence of the full pp neutrino flux expected according to the ''standard solar model'' together with a reduced flux of B-8+Be-7 neutrinos as observed in the Homestake and Kamiokande experiments. Astrophysical reasons remain as a possible explanation of the solar neutrino problem. On the other hand, if the result is to be interpreted in terms of the MSW effect, it would fix neutrino masses and mixing angles within a very restricted range.

The existing high-statistics xF3 determination by the CDHSW collaboration is compared to our data. The data presented here constitute the first corroboration of the QCD prediction of xF3 evolution at low-x, and yields LAMBDA(MSBAR) = 210 +/- 28 +/- 41 MeV, and a determination of the GLS sum rule at Q2 = 3 GeV2, S(GLS) = integral-1/x xF3/x dx = 2.50 +/- 0.018(stat.) +/-0.078 (syst.).

Researchers, however, have known for many years that safety performance is affected by an organization's socially transmitted beliefs and attitudes toward safety. The safety culture of an organization is very complex and hard to study, but it is possible to examine norms that make up the culture. A written survey instrument was developed to examine the safety culture of EG&G Idaho, Inc., a Department of Energy (DOE) Contractor at the Idaho National Engineering Laboratory (INEL). This instrument was developed by determining safety norms of the organization and then developing statements that reflect those norms for inclusion in the survey instrument. The survey instrument was used by DOE to assess the safety culture at INEL. Statistical tests on the data from the survey showed that the instrument had good internal consistency. The survey instrument, which is included in the article, appears to have merit for use by non-INEL organizations. This article also discusses how the survey should be administered and how the results can be used to help improve the safety culture of an organization.

For many years, the modeling commonality of these apparently diverse disciplines was either largely ignored or unnoticed by many members in both technical communities. Apparently, with the exception of a few visionaries such as the Mathematical Application Group, Inc. (MA GI), each community was not sufficiently aware of what the other was doing. This common basis included the treatment Of neutral particle transport through complicated geometries in three-dimensional space. In one instance, it is called the Boltzmann transport equation, while in the other, it is commonly referred to as the rendering equation. Even though the modeling methods share a common basis, the initial strategies each discipline developed for variance reduction were remarkably different. Initially, the reactor physicist used Russian roulette, importance sampling, particle splitting, and rejection techniques. In the early stages of development, the computer scientist relied primarily on rejection techniques, including a very elegant hierarchical construction and sampling method. This sampling method allowed the computer scientist to viably track particles through irregular geometries in three-dimensional space, while the initial methods developed by the reactor physicists would only allow for efficient searches through analytical surfaces or objects. As time goes by, it appears there has been some merging of the variance reduction strategies between the two disciplines. This is an early (possibly first) incorporation of geometric hierarchical construction and sampling into the reactor physicists' Monte Carlo transport model that permits efficient tracking through nonuniform rational B-spline surfaces in three-dimensional space. After some discussion, the results from this model are compared with experiments and the model employing implicit (analytical) geometric representation.

There are concerns that these statistical uncertainties may be substantially nonconservative in some classes of problems, especially reactor eigenvalue problems with the additional complication of a generation-to-generation source. Optimization of the Monte Carlo random walks may introduce further nonconservatism. Calculations are reported that quantify the reliability of the uncertainty by comparing an ensemble of Monte Carlo predictions of means and uncertainties to the true means for a liquid-metal fast reactor. It was found that the number of samples falling beyond a 90% confidence limit interval was typically not far from the expected 10%. However, 2 samples out of approximately 300 were beyond four standard deviations, while for a normal distribution there is < 1 chance in 10 000 that a sample will be beyond four standard deviations.

In these studies, liposomes composed of phosphatidylcholine and cholesterol, additionally containing monosialoganglioside (G(M1)) or polyethylene glycol conjugated to phosphatidyl-ethanolamine (PEG-PE), were used. Three antitumor lipophilic prodrugs, N-trifluoroacetyl-adriamycin-14-valerate (AD32), araC-diphosphate-diglyceride (araCdPdG), and 3',5'-o-dipalmitoyl-5-fluoro-2'-deoxyuridine (dpFUdR), were used to examine the effect of lipophilic prodrug incorporation into long-circulating liposomes and immunoliposomes on their biodistribution in mouse. Biodistribution studies with antibody-free liposomes containing lipophilic prodrugs showed that the activities of G(M1) or PEG2000-PE in prolonging the circulation time of liposomes appeared to be preserved in the presence of each of the three lipophilic prodrugs at a drug/lipid molar ratio of 3:97. The effect of lipophilic prodrug incorporation on target binding of immunoliposomes was then examined using a mouse model. Incorporation of AD32 or dpFUdR into immunoliposomes, directed to the normal endothelium, did not affect the targetability of immunoliposomes, suggesting a potential effectiveness of these lipophilic prodrug-containing immunoliposomes in therapy for lung tumors. On the contrary, incorporation of araCdPdG resulted in significantly reduced target binding of immunoliposomes by yet unknown mechanism(s).

The twins usually lie on only one of these possible planes in any single grain, but occasionally both twin systems are observed within a grain. When this occurs, the terminations of one set of twins on the coherent twin planes of the other take a characteristic form, with the twins tapering down nearly to zero thickness. We have obtained high-resolution transmission electron microscopy images of these twin terminations, which clearly indicate that the terminating twins embody both possible twin variants, with coherent interfaces on two nearly perpendicular planes. The corners where these interfaces meet are well described as wedge disclinations of small rotation angle. We discuss the shapes of the terminating twins in terms of the interactions between pairs of adjacent disclinations.

The spectrum of AMT-induced plasmid DNA relaxation fits closely with the absorbance spectrum of AMT in the spectral region between 313 nm and 405 nm but deviates at wavelengths shorter than 313 nm. This assay also reveals that the psoralen photosensitization reaction with DNA also produces piperidine-labile sites. Addition of mannitol and azide partially quenches the supercoil relaxation reaction, evidence for a role of Type II photosensitization pathway.

Multiple date SPOT panchromatic data (10- by 10-m spatial resolution) obtained in April and October of 1988 through 1990 were analyzed using digital image processing techniques to inventory the spatial distribution of cattail and waterlily beds in a freshwater reservoir located on the Savannah River Site in South Carolina. The remote sensing derived wetland information was highly correlated with in situ cattail and waterlily measurements (correlation coefficients ranging from 0.86 to 0.95) made at 48 transects during the 1988 and 1989 growing seasons. In addition, the creation of a multiple date color composite using October 1988, 1989, and 1990 SPOT panchromatic data proved to be a very effective method to visually identify the change in aquatic macrophyte distribution through time. These remote sensing techniques should be applicable to other southeastern lakes and reservoirs, which have large beds of cattails and waterlilies with similar phenological cycles and lake hydrology.

Our method determines the formation energies of native point defects and of acceptor dopants as a function of the relative abundance of Zn, Se and the dopant atoms, resulting in a map of the concentrations of defects and dopants over the entire thermodynamically allowed range of conditions. For native point defects, which were often assumed to compensate the doping of ZnSe, we show that their concentrations are negligibly small over most of the range of allowed stoichiometry. For a ZnSe acceptor-doped with Li(Zn) or Na(Zn), we find that compensation by Li(i) and Na(i) donors is possible, but can be avoided in a sufficiently Se-rich environment. The most stringent limits on acceptor doping of ZnSe come from the solubility limits of the three dopants. Our calculations show that Na(Zn) has a very low solubility limit, with a much higher limit for Li(Zn), and the highest for N(Se). C1 NATL RENEWABLE ENERGY LAB, GOLDEN, CO USA.

We find Fe3+ in three environments. Fe substitutes in the Cu(1) chain sites in 5-fold and 6-fold coordination, and in the Cu(2) plane sites in 5-fold coordination. The onset of magnetic ordering is near 65 K. This latter result is much lower than expected given the high Fe content and 5-fold and 6-fold coordination, which trap hotes in the Cu(1)Oy planes. We interpret the lower magnetic ordering temperature to be due to more efficient transfer of available untrapped holes from the Cu(1)Oy planes to the Cu(2)O2 sheets.

Our photoelectron spectra, recorded at hnu = 29.2 eV, give ratios of P-3(2):P-3(1):P-3(0) = 100:40.5:9.5 for 3p photoionization and P-3(2):P-3(1) = 100:31 for 3s photoionization. While the results for 3p ionization are in ar-cord with predictions based on a simple geometric analysis, the contribution of the P-3(1) state in 3s photoionization is larger than that predicted by this simple model. The geometric predictions are also compared with results from a similar measurement of the population of the 4p-1(3p(J)) states produced in the 4p ionization of Br and with earlier work on the production of 3D2,1,0 states in d-shell photoionization of Cu and Ag.

We show that the resulting set of coupled-channel equations, originally derived by Gavrila and Kaminski [Phys. Rev. Lett. 52, 613 (1984)], represents electron scattering by a vibrating charge initially in a highly excited state. This formulation leads to a mechanical model of the atom-field interaction from which we can draw better insights into the nature of the process. We solve these coupled equations numerically in the close-coupling approximation by a combination of the linear algebraic and R-matrix propagator approaches. We specifically treat electron-proton collisions in an intense field and investigate the capture-escape resonances over a range of intensities and frequencies. We also investigate multiphoton ionization of atomic hydrogen in various intensity regimes. We extend our calculations for single-photon ionization into the superintense regime ( > 10(16) W/cm2) and compare our results with results from time-dependent solutions of the Schrodinger equation.

Large-basis calculations for the Pb on Pb system put a probable upper limit of the order of 10 b on the correction to perturbative calculations of the K-orbit-electron-positron pair production at ultrarelativistic heavy-ion colliders such as RHIC; this is to be added to the perturbative value of about 115 b.

The lifetime for the transition has been measured for each isotope and found to be tau0(107)=3.98(37) X 10(-12) sec and tau0(log)=2.84(32) X 10(-12) sec. From the measured lifetimes a value is inferred for the absolute value of the 2 P-3(0)-2 P-3(1) fine-structure splitting \DELTAE0-1\ in Ag45+ with the result \DELTAE0-1\ = 0.79(04) eV, where the uncertainty is the experimental uncertainty taken at the 1sigma confidence level. This result is compared with calculations based on the multiconfigurational Dirac-Fock method, the unified method, and recent results from the relativistic configuration-interaction method.

At higher temperatures the transition is to a quasi- or random ferromagnet. The transition occurs at a concentration x(t) = 0. 62 +/- 0.01 in the crystalline Laves-phase compounds DyxY1-xAl2. At concentrations above x(t), a line of transition is observed between the paramagnetic and random ferromagnetic phases, as found previously. This line is characterized by the crossover exponent phi(DELTA) = 0.80 +/- 0.08, in good agreement with prediction. Two multicritical points have been identified at x(t) = 0. 62 +/- 0.01, T(t) = 29.5 +/- 0.1 K and at around x(t)' = 0. 87, T(t)' = 45.4 K. C1 BROOKHAVEN NATL LAB,DEPT PHYS,UPTON,NY 11973.

We consider phonon potential energies of the form approximately Q(n), as well as double-well potentials approximately Q4 - alphaQ2. For phonon potential energies with a power law approximately Q(n), the resistivity at high temperature is proportional to T2/n. At low temperature, the resistivity rises rapidly and then flattens, thereby forming a knee shape. This behavior explains the resistivity of cuprate superconductors in the normal state. We also correlate resistivity with the superconducting transition temperature T(c), to see whether anharmonic phonons cause the pair binding in the superconductor. Our results show that a reasonable set of parameters to explain the resistivity is unable to explain the T(c) of these materials. C1 OAK RIDGE NATL LAB,DIV SOLID STATE,OAK RIDGE,TN 37831.

Magnetism and covalency are investigated in a parameter space of strong intersite electron-lattice coupling and varying on-site electron-electron repulsion strength. In a crossover region between a charge-density-wave phase driven by intersite electron-lattice coupling and an antiferromagnetic phase driven by on-site electron-electron repulsion, a bond-order-wave state, a spin-Peierls state, and a mixed state of spin-Peierls bonds and antiferromagnetic spins axe found to be stable and caused by competing magnetism and covalency of different relative strengths. Doping states depend qualitatively upon the nature of these global phases. In particular, separation of spin and charge is observed in the background of the bond-order-wave state as a consequence of local competition between magnetism and covalency.

Submillimeter measurements from 25 to 700 cm-1 were made at 2 K by a direct absorption technique in which the film acts as the absorbing element in a composite bolometric detector. Microwave measurements near 10 GHz (0.3 cm-1) were made on five of the same films by resonance techniques at 4 K. The approximately 0.4-mum-thick films were grown epitaxially on SrTiO3, LaAlO3, and MgO by off-axis sputtering and laser deposition. The absorptivities measured for all films studied are qualitatively similar, increasing smoothly with frequency, with no gaplike features below the well-known absorption edge at 450 cm- 1. A successful three-parameter fit is obtained for all of our films. This fit can be interpreted either in terms of a weakly coupled grain model or a homogeneous two-fluid model with residual normal conductivity. The fitting parameters correspond to a grain-penetration depth lambda(g) equal to the muon-spin-relaxation value of 140 nm, and to reasonable grain properties. They also give carrier densities in reasonable agreement with optically determined plasma frequencies and conductivities in agreement with a Kramers-Kronig analysis of the absorptivity data.

For temperatures larger than the antiferromagnetic ordering temperature of the Cu lattice, T(N), we have identified four different sites of Gd3+ as expected for twinned crystals and we are able to fit the data for all directions of the magnetic field. Samples annealed under vacuum or oxygen show only small changes on their crystal-field parameters and g values. For temperatures smaller than T(N), the EPR lines are further split due to the internal magnetic field acting at the Gd site associated with the antiferromagnetic ordering of the Cu lattice. The temperature dependence of the splitting of the resonance lines allow us to calculate the moment per Cu ion. A value of approximately 0.6mu(B) per Cu ion at T = 0 K is inferred, with the Cu moments lying in the bc plane about 5-degrees from the c axis. The data only can be fit for all the directions of the applied magnetic field if other mechanisms such as a Heisenberg type of exchange between the Cu and Gd moments or a distortion of the lattice below T(N) are included.

From transport measurements it is possible to identify at least two regions separated by a boundary identified as a vortex-glass transition, with the region below the boundary having zero linear resistance and that above having a low-current linear resistivity which seems to be associated with thermally activated flux motion. Evidence for flux pinning above the glass transition suggests that there is a loss of critical current density (J(c)) rather than an onset of reversible magnetic behavior at the glass transition. The complications of using first-harmonic ac susceptibility (chi(ac)) to define the IRL are discussed. In addition, the third-harmonic chi(ac) is shown to measure the same property that the first-harmonic chi(ac) measures: ac magnetic-field penetration rather than the loss of J(c). Results and a theoretical model showing that there are significant differences between field-cooled dc magnetization measurements when the data are collected on warming versus collecting data on cooling are presented.

In addition to seeing a photoelectron feature from the 1sigma(g) molecular state, other photoelectron peaks were seen at lower kinetic energies. A peak located -13.5 eV from the 1sigma(g) feature is attributed to resonant photoelectron scattering. A smaller peak located -29.0 eV from the 1sigma(g) feature can be explained by a double scattering event. The magnitude of the electron energy loss during scattering is larger in the solid phase than in the gas phase and physical mechanisms for this are discussed.

The head-on collisions of H+, D+, and He++ ions with a nickel atom are chosen as models. Ionic trajectories are calculated classically taking fully into account the distance-dependent repulsive potential of the nickel 3d electrons. For the electronic part of the Hamiltonian the most general on-site interaction terms allowed by atomic symmetry are used. The total electronic many-body states are classified by group-theoretical methods with respect to the orbital and spin ''good'' quantum numbers L, L(z), and S(z); the latter two are conserved during the collision process. The nickel configurations 3d9, 3d8, and 3d7 axe taken into account. They correspond to the treatment of elastic scattering, one-electron capture, and two-electron capture on the same footing. The time-dependent Schrodinger equation for this system is solved exactly. Experimentally accessible quantities such as the occupation numbers of all the states as well as the zero-, one- and two-electron-capture probabilities are monitored along the trajectories of the scattering species on the femtosecond time scale. Probabilities of 21% and 0.35% for one- and two-electron capture, respectively, are found, in good agreement with experiments on surfaces. Similarly, a spin polarization between -60% and -100% is calculated. It turns out that this predominant capture of minority electrons is a consequence of angular-momentum conservation and is strongly enhanced by electron correlations. The result implies that the probing of magnetism by electron capture occurs on a significantly longer time scale than the probing of single-electron properties.

The temperature dependence of the 0 phonon frequency and linewidth is fit using the results of a perturbation calculation of Raman scattering from anharmonic vibrations with very good results, provided both third- and fourth-order terms in the phonon self-energy are included. Temperature-dependent asymmetric Fano line shapes of the apex 0 modes, which are observed especially well in TlBa2CaCu2O7, suggest Significant coupling of these modes to the background continuum. From the temperature dependence of the background intensity we deduce that the Raman scattering continuum in the region 100-1000 cm-1 contains significant two-particle scattering. The zz polarization of the observed scattering suggests the background is due to two-phonon rather than two-magnon scattering. The Fano line shape and the temperature dependence of the asymmetry can then be attributed to anharmonic interactions. C1 SANDIA NATL LABS,ALBUQUERQUE,NM 87185. SANDIA NATL LABS,LIVERMORE,CA 94551.

Steady increases in R(H) with delta suggest that deoxygenation reduces the density of states which, according to BCS theory, should lead to corresponding decreases in T(c) . In contrast, two well-known plateaus occurring at 90 K and 60 K were observed in T(c) vs delta. Others have ascribed these plateaus to either electronic phenomena or phase separations. We find that in the 90-K plateau, the critical current density J(c) (delta, H = 0) decreases with 8 and extrapolates toward zero at the edge of the plateau, while the relative-field dependence of J(c)(delta,H) and the flux-creep pinning energies are independent of delta. These observations suggest that the phase-separation scenario occurs on the 90-K plateau. However, electronic origins cannot be ruled out at present due to difficulties in determining the equilibrium superconducting properties of oxygen-deficient YBa2Cu3O7-delta films.

To determine the location of the vortex, the Pb film is fabricated to be one electrode of a cross-strip superconductor/normal-metal/insulator/superconductor (SNIS') Josephson junction. Distortions in the Fraunhofer pattern specify the vortex location. As the temperature is raised toward T(c), the vortex depins from the artificial pinning site and reproducibly moves through the same sequence of other pinning sites before it leaves the junction area of the Pb film. The first thermal depinning occurs when the order parameter of the bulk superconductor is about 20% of the T = 0 value. The trajectory is not random.

The proposed charge-density-wave satellites, seen along [110] directions with electron diffraction, have been attributed previously to electron-beam irradiation effects even though their positions seem to vary smoothly with K content. A careful x-ray search in all equivalent [110] directions of the pseudocubic reciprocal lattice revealed no satellite structure in either of the samples. We therefore conclude that the reported electron-diffraction results are indeed induced through electron-beam effects and discuss possible interpretations of our observed absence of these satellites in the as-grown crystals and their dependence on electron-beam irradiation.

We show that the sign of this current is determined by the derivative of the kinetic energy with respect to the chemical potential. We present exact numerical results from diagonalization of finite clusters to support our arguments. In the case of the Hubbard model with strong on-site repulsion the sign of the equilibrium Hall conductivity is electronlike for a small number of particles and holelike close to half filling.

Alternate use of a liquid-hydrogen hydrogen target provided a comparison of free and quasifree p-p over arrow pointing right scattering. The precision of the data is in general +/-0.01 to +/-0.02, although some of the p-p over arrow pointing right data for 797 MeV are at the precision level of +/-0.005. For c.m. angles theta* greater-than-or-equal-to 22-degrees there is no difference between quasifree and free results at either energy. The data are compared with the predictions of several phase-shift analyses. In a search for more pronounced quasifree scattering effects, a small amount of p-''p'' over arrow pointing right data were taken with a carbon target. C1 LOS ALAMOS NATL LAB,LOS ALAMOS,NM 87545.

Considering idealized two-dimensional matter, for which it is practical to simulate the Boltzmann-Langevin equation directly, we demonstrate that the number of test particles per nucleon can be adjusted so that the corresponding BUU calculation yields a good reproduction of the spontaneous clusterization occurring inside the spinodal region. This approximate method may therefore provide a relatively easy way to introduce meaningful fluctuations in simulations of unstable nuclear dynamics. C1 LNS,CATANIA,ITALY.

The three resonances have different characteristic angular distributions. Partial angular distributions were measured on V-51 and '' In and observed to have J(pi)=0+, 1-, and 2+ shapes, respectively. Based on their centroid energies, angular distributions, and observed cross sections, we identify the resonances as the double isobaric analog state, the giant dipole built on the isobaric analog, and the double giant dipole resonance. The new observations are in close agreement with the gross features reported recently for the double giant resonances, and provide some of the best signals obtained to date for the double resonance states in nuclei.

Evidence for a change of slope in the cross section near Q2 = 1 (GeV/c)2 has been obtained. The data are compared to nonrelativistic calculations, which predict a strong influence of meson-exchange currents. The data are also compared to a hybrid quark-hadron model. None of these calculations agrees with the data over the entire measured range of Q2. The ratio of inelastic structure functions W1(Q2,E(np))/W2(Q2,E(np)) is extracted from the present results and previous forward angle data.

A scintillation counter array downstream of the target was used to sample the charged particle multiplicity of each event and hence give some information on the impact parameter of the collision. Including results from previous experiments, space-time dimensions of the pion source are now available for mass-symmetric collisions in the mass range of A = 40 to 139. The sources are oblate for nearly all systems, except for La + La central collisions viewed near 45-degrees in the laboratory (90-degrees in the center of mass) where the source is spherical. The perpendicular radius R perpendicular-to is never less than 4 fm, regardless of the centrality of the La + La collision. Furthermore, R perpendicular-to seems independent of the mass of the collision system. C1 TEXAS A&M UNIV SYST,INST CYCLOTRON,COLL STN,TX 77843.

H. Stelson. The systematics of the threshold barriers derived from the data are examined in terms of a simple picture in which the onset of free neutron flow between the collision partners promotes fusion at a large distance. A consistent correlation between observed barrier shifts and the conditions necessary to maintain free neutron flow has emerged.

We propose a new method, which we call global hydrodynamics, for solving the hydrodynamic equations, with two objectives in mind: first to make the calculations easier by using an approximate but very efficient scheme, and second to gain new insights into the dynamics by establishing the global expansion characteristics as a new viewpoint. The method consists of integrating the partial differential equations of hydrodynamics over an azimuthally symmetric region to obtain global conservation laws from the local ones. Assuming specific thermal and velocity profiles we derive ordinary differential equations for the most relevant dynamical quantities which are easy to solve. This enables us to do large numbers of runs easily and thus to perform a systematic scan of the whole range of possible initial conditions, following each case individually until freeze-out. By comparing the computed particle spectra to experiments it is possible to restrict the initial conditions and obtain quantitative information on the early dynamics of relativistic nuclear collisions.

In particular, a covariant derivative expansion of the one-loop effective action is presented and then modified by an infinite resummation so as to provide agreement with the exactly calculable one-loop effective potential. Essential to this technique is a self-consistently defined infrared cutoff which determines the prefactor in semiclassical calculations. Using this prefactor, densities of monopole and dyon plasmas are calculated, and it is found that if such plasmas do exist at finite temperature, then the solitons involved must be overlapping one another. It is also shown that no consistent perturbative or nonperturbative approximation can give rise to a linear term in the SU(2) effective potential, since such a term would not be gauge invariant. Finally, contour plots of the SU(3) A0 effective potential are presented. RP CHAPMAN, S (reprint author), LAWRENCE BERKELEY LAB,DIV NUCL SCI,BERKELEY,CA 94720, USA.

Characteristic Er Kalpha x rays and an 80.9-keV gamma ray were observed to decay with the half-life of Tm-147. The 80.9-keV gamma ray is proposed to be the transition connecting the first-excited (d3/2) and ground (s1/2) neutron-hole states in Er-147. The Tm-147 (Ec+beta+)-decay strength was deduced from K x-ray and annihilation radiation intensities. A comparison of this strength with the intensity of the 1.045-MeV proton peak leads to a Tm-147 direct-proton-decay branch of 15(5)%. C1 EASTERN KENTUCKY UNIV,RICHMOND,KY 40475.

The antiproton multiplicity at laboratory rapidities 1.0 to 1.6 shows almost no dependence upon the target mass. The pBAR production for p + Be is somewhat lower than an estimation based upon 19-24 GeV/c p + p data.

One irregular and two regular bands of M1 transitions have been observed following the Er-170(Si-30,4n) and Yb-176(Mg-26,6n) reactions. Transitions linking the most intense regular band to the low-lying negative-parity yrast levels are observed, establishing excitation energies, spins, and probable parities of the band members. In contrast, no such transitions have been found for the irregular band and the weaker regular band. The bands are interpreted as corresponding to collective oblate rotation, arising mainly from deformation-aligned high-j, shape-driving quasiproton excitations across the Z = 82 shell gap, coupled to rotation-aligned quasineutrons.

Due to the high threshold energy, antiprotons mostly arise from the highest energy baryon-baryon collisions. We have identified a three-body screening mechanism which strongly reduces the subsequent absorption of antiprotons in the medium. We have used a relativistic cascade code to study this effect, and find that it is essential to obtaining good agreement with recent pBAR production data from Brookhaven experiment E802.

The nu(mu) (nu(mu)BAR) beam had an average energy of 80 GeV (70 GeV). From a sample corresponding to approximately 28 000 charged-current interactions, net signals of (53 +/- 9) mu+/- pi-/+ coherent events and (19 +/- 7) mu+/- pi-/+ pi0 coherent events are extracted. For E > 10 GeV, the coherent pion production cross section is determined to be (3.2 +/- 0.7) X 10(-38) cm2 per neon nucleus whereas the coherent rho production cross section is (2.1 +/- 0.8) x 10(-38) cm2 per neon nucleus. These cross sections and the kinematical characteristics of the coherent events at Absolute value of t < 0.1 GeV2 are found to be in general agreement with the predictions of a model based on the hadron dominance and, in the pion case, on the partially conserved axial-vector current hypothesis. Also discussed is the coherent production of systems consisting of three pions. C1 UNIV BIRMINGHAM,BIRMINGHAM B15 2TT,W MIDLANDS,ENGLAND.

To this end, we consider the Drell-Yan production experiment either with an 800 GeV proton beam or with a 200 GeV pi+/- or K+/- beam, readily feasible at Fermilab (as a fixed target experiment). Numerical results indicate that the measurement of the p/N (proton-to-nucleon, i.e., normalized proton-to-deuteron) Drell-Yan production cross-section ratio is a suitable choice for unraveling the dBAR over uBAR asymmetry in a proton. The results also suggest that an experiment with a 200 GeV pi- or K- beam is not suitable for this particular purpose although the calculated ratio differs significantly from unity.

The theoretical uncertainties in the normalization of the top-quark production cross section and background signals make it important to look for the top quark in a final state where the top-quark mass is reconstructible from the final state. The W + 4 jet final state offers a simple and direct way to reconstruct the top-quark mass through final-state invariant masses. It is shown that from a theoretical viewpoint the top quark is easily recovered from this W + 4 jet cross section. The only limitation comes from the experimental ability to correctly reconstruct the invariant masses which might contain multiple jets. C1 FERMILAB NATL ACCELERATOR LAB,BATAVIA,IL 60510.

We study the standard model constraints in the sin2alpha-sin2beta plane. We use the results from recent analyses of f(B) and tau(b) \V(cb)\2 which take into account heavy-quark symmetry considerations. We find sin2beta greater-than-or-equal-to 0.15 and most likely sin2beta greater-than-or-similar-to 0.6, and emphasize the strong correlations between sin2alpha and sin2beta. Various schemes for quark mass matrices allow much smaller areas in the sin2alpha-sin2beta plane. We study the schemes of Fritzsch, of Dimopoulos, Hall, and Raby, and of Giudice, as well as the ''symmetric Cabibbo-Kobayashi-Maskawa'' idea, and show how CP asymmetries in B decays will crucially test each of these schemes.

FORMALISM AND MESON FORM-FACTORS SO PHYSICAL REVIEW D LA English DT Article ID EFFECTIVE FIELD-THEORY; RESONANCE PHYSICS; QCD; DECAYS; ANNIHILATION; MODEL; STAR AB In the heavy-quark effective theory, hadronic matrix elements of currents between two hadrons containing a heavy quark are expanded in inverse powers of the heavy-quark masses, with coefficients that are functions of the kinematic variable upsilon - upsilon'. For the ground-state pseudoscalar and vector mesons, this expansion is constructed at order 1/m(Q)2. A minimal set of universal form factors is defined in terms of matrix elements of higher-dimensional operators in the effective theory. The zero recoil normalization conditions following from vector current conservation are derived. Several phenomenological applications of the general results are discussed in detail. It is argued that at zero recoil the semileptonic decay rates for B --> Dlnu and B --> D*lnu receive only small second-order corrections, which are unlikely to exceed the level of a few percent. This supports the usefulness of the heavy-quark expansion for a reliable determination of V(cb). RP FALK, AF (reprint author), STANFORD UNIV,STANFORD LINEAR ACCELERATOR CTR,STANFORD,CA 94309, USA.

BARYON FORM-FACTORS SO PHYSICAL REVIEW D LA English DT Article ID EFFECTIVE FIELD-THEORY; MESONS; DECAYS; QCD AB The analysis of 1/m(Q)2 corrections of the previous paper is extended to the semileptonic decays of heavy baryons. We focus on the simplest case, the ground state LAMBDA(Q) baryons, in which the light degrees of freedom axe in a state of zero total angular momentum. The formalism, while identical in spirit, is considerably less cumbersome than for heavy mesons. The general results axe applied to the semileptonic decay LAMBA(b) --> LAMBDA(c)lnu. An estimate of the leading power corrections to the decay rate at zero recoil, which are of order 1/m(Q)2, is presented. It is pointed out that a measurement of certain asymmetry parameters would provide a direct measurement of 1/m(Q)2 corrections. Finally, it is shown how the analysis could be extended to include excited heavy baryons such as the SIGMA(Q) and the SIGMA(G)*.

Since the allowed number of vertex types is odd, the arrow-reversal symmetry of the system is broken by construction. Due to this, the exact solution obtained and the phase diagram are very different from those of the symmetric six-vertex model. A connection to the asymmetric six-vertex model (of which the five-vertex model is an extreme case) is made. The different regions of the phase diagram are described and the transitions between them are analyzed. Several aspects of the phase diagram are unusual, i.e., the ordered phases (both ferroelectric and antiferroelectric) are frozen-in phases and the disordered phase is replaced by a ferrielectric phase. In the free-fermion case, the known results of the modified potassium dihydrogen phosphate model are recovered. C1 SCUOLA INT SUPER STUDI AVANZATI, I-34014 TRIESTE, ITALY.

A. Rand and L. S. Young (Springer, New York, 1981)]. The focus of this paper is on the selection of appropriate lag-time and embedding-dimension values with an emphasis on the relationship between those parameters and data-measurement considerations. We are particularly interested in the effect that low-pass filtering has on the appearance and measured properties of reconstructed attractors. Empirical results are presented using data measured from a laboratory fluidized bed and from data generated by integrating the Lorenz [J.

For all viscosity ratios, the initial flows had an unstable, fractal character which crossed over to stable, compact flow on a time (or length) scale which increased with the viscosity ratio. An empirical scaling of the data enables an asymptotic characterization of both this time scale tau almost-equal-to M(phi)t, where phi(t)=0.17+/-0.03, as well as the front velocity upsilon almost-equal-to M(epsilonphi)t where epsilonphi(t)=0.07+/-0.02. A comparison with identical simulations of radial flow indicates that the same characteristic length scale applies in both linear and radial geometries l almost-equal-to M(phi)l where phi(l) = 0.24+/-0.06, while the time scales differ because of the different relations between time and size in the two geometries.

We present results from our analysis of spectroscopic measurements of x-ray Kalpha satellites emitted from a target irradiated by an intense-light ion beam. In this experiment, performed on the Particle Beam Fusion Accelerator-II device at Sandia, an Al target was irradiated with a 4-6 MeV proton beam with a peak power density of 1-2 TW/cm2. Up to 15% of the beam electrical current was in the form of carbon contaminants. A time-integrated spectrum was obtained with a resolution of lambda/DETLAlambda > 1200. In our analysis, collisional radiative equilibrium (CRE) calculations were performed to study the dependence of the Al Kalpha emission spectrum on plasma and beam properties. Good agreement is obtained between calculated satellite spectra and the emission features observed in the experimental spectrum. We find that excited states with M-shell spectator electrons contribute significantly to Kalpha satellite emission spectra, exhibiting relatively broad lines at wavelengths blueshifted with respect to those originating from ground-state configurations. Because of opacity effects, it is likely that only radiation emitted from the outer skin of the target plasma was seen by the detector in the experiment. It is also shown that resonant self-absorption can skew the spectrum towards apparent higher ionization stage. Our results suggest that emission spectroscopy of x-ray satellite lines from thin tracer layers offers a potentially valuable technique for determining plasma conditions in intense-light-ion-beam experiments.

The plasma is created by irradiating uncoated transparent planar glass targets with 1.0-ps FWHM laser pulses at a peak intensity of 2.0 X 10(13) W/cm2. Time-resolved measurements using a probe light pulse incident from the backside are presented, revealing two competing mechanisms: one is highly absorptive due to a bulk underdense plasma formed behind the target surface, and the other is highly reflective due to an overdense plasma layer at the surface. A simple self-consistent and analytical model, similar to the avalanche model, is proposed, leading to both time-dependent and time-integrated solutions to the evolution of plasma density profiles and characteristics of high-intensity-laser-pulse propagation and absorption in the transparent material. Calculations of the probe light interacting with this plasma show that excellent agreement with experimental measurements can only be obtained by including a contribution from the bulk plasma formed behind the surface. Experimental measurements with Au-coated targets are also shown to illustrate elimination of the bulk plasma. C1 LAWRENCE LIVERMORE NATL LAB, LIVERMORE, CA 94550 USA.

The optimal network is shown to be surprisingly close but not identical to a linear high-pass filter. A suitably constrained deconvolution method is shown to uncover accurately the underlying jet distribution in spite of the broad network response. Finally, we show that possible changes of the jet spectrum in nuclear collisions can be analyzed quantitatively, in terms of an effective energy loss, with the proposed method.

The argument given to support these claims neglected the presence of the fluid boundary. We prove that the Boltzmann temperature is in fact always negative, and present evidence that the vortex clumping that has been observed in simulations is consistent with ergodic dynamics.

B. Mineev, Physica D 43, 288 (1990)] we study here multidimensional growth for arbitrary elliptic equations, describing inhomogeneous and anisotropic pattern-formation processes. We find that these nonlinear processes are governed by an infinite number of conservation laws. Moreover, in many cases all dynamics of the interface can be reduced to the linear time dependence of only one ''moment'' M0, which corresponds to the changing volume, while all higher moments M(l) are constant in time. These moments have a purely geometrical nature, and thus carry information about the moving shape. These conserved quantities [Eqs. (7) and (8) of this article] are interpreted as coefficients of the multipole expansion of the Newtonian potential created by the mass uniformly occupying the domain enclosing the moving interface. Thus the question of how to recover the moving shape using these conserved quantities is reduced to the classical inverse potential problem of reconstructing the shape of a body from its exterior gravitational potential. Our results also suggest the possibility of controlling a moving interface by appropriately varying the location and strength of sources and sinks.

The solution concentrations of tests at different SA/V do not generate a single curve, as predicted by current theory, rather tests at higher SA/V have higher solution concentrations than tests at lower SA/V at equivalent (SA/V)t. The lack of correlation of tests at different SA/V is attributed to differences in the leachate pH. Tests at higher SA/V attain higher leachate pH values due to initial ion exchange reactions because of smaller solution volumes. The pH differences then affect the hydrolysis reactions which release boron and silicon. It is shown that, if the pH dependence of hydrolysis reactions is accounted for in the rate law, a correlation variable of the form (SA/V)t does not exist.

The results are in agreement with an application of the test-particle superposition principle. They are interpreted physically in terms of the concept of the ''gyrokinetic vacuum,'' whose large (tensor) dielectric constant embodies the shielding effects of the polarization drift and the inductive electric field. The calculations are performed entirely with gyrokinetic response functions, although the relations to the conventional Vlasov dielectric are also described. The previous heuristic results of Krommes et al. [Phys. Fluids 29, 2421 (1986)] are recovered systematically. A nonrelativistic covariant formalism is used to derive the finite-beta results (where beta is the plasma pressure). The wave-number power spectra of the charge density, electrostatic potential, and perpendicular electric field are independent of beta, while those of the parallel current, parallel vector potential, and perpendicular magnetic field are increasing functions of beta. These results are derived both by exact integrations of the frequency spectra and, in the appropriate limit, by resonance integrations over weakly damped normal modes. To interpret the latter results, a new form for the unusual energy conservation law of gyrokinetic plasma is exhibited and a new formula for the gyrokinetic plasmon action N(k) valid at finite beta is derived. The fluctuation spectra for the normal modes can then be derived by setting the plasmon energy omega(k)N(k) to T/2. The power spectrum of the inductive component of the parallel electric field is dominated by high-frequency, non-normal-mode noise.

This model treats both the dynamics associated with the formation of a polarization field and the generation and propagation of electromagnetic waves. In general, the results indicate that, to zeroth order, the plasma cloud behaves like a large dipole antenna oriented in the direction of the polarization field which oscillates at frequencies defined by the normal mode of the system. The magnitude of the radiation field and the amount of plasma momentum and energy carried away by and stored instantaneously in the fields are discussed only qualitatively in this paper, quantitative results for specific cloud parameters and scaling laws for the magnitude of the fields and the slowing down of the plasma cloud are presented in a companion manuscript.

The results indicate that radiation damping plays an important role in defining the plasma cloud evolution, causing a rapid decay of the polarization field and a loss of plasma kinetic energy and momentum on time scales comparable to several ion gyroperiods. The radiation spectrum consists of a burst of chirped, high-frequency (in the range of the cloud plasma frequencies) waves, followed by a pulse of whistler waves, and subsequently by ion cyclotron emission.

The resistive one-fluid code TSC, where the plasma boundary is defined by the separatrix, is used to follow the nonlinear evolution. Contrary to the results of previous ideal MHD simulations, nonlinear stabilization is not observed for motions towards an x point. Apparently this is due to the absence of internal magnetic islands inside the plasma. For motions in the direction between two x points, however, nonlinear saturation is seen, consistent with the analytical theory. C1 PRINCETON UNIV,PLASMA PHYS LAB,PRINCETON,NJ 08543.

The monitoring system includes a particle impact probe and supporting electronics for probe excitation and data treatment and storage. The probe and electronic system can measure the x, y and z components of momentum transferred to the probe head by individual 700- and 3 200-micrometer particle impacts spaced more than 500 micro-seconds apart. When calibrated, the monitoring system can also measure the x, y and z components of solids force exerted on the probe head in dense fluidized beds. The prototype probe has a 0.318-centimeter outside diameter, 7.62-centimeter long, stainless steel tube base with a 0.318-centimeter diameter nylon sphere probe head mounted at one end. When impacted by particles in a 15.3-centimeter diameter fluidized bed, the probe head produced xyz three-axis motion in a miniature electrode system mounted within the tube base. The signals produced by the electrode system were calibrated to produce either the components of the momentum vector of the probe head during individual particle impacts or the three components of the force exerted on the probe head during multiple, closely spaced particle impacts.

Currently dominant, large-scale storage architectures, built around central, shared storage systems with CPU-connected devices are reaching economic and technological limitations and no longer meet performance, capacity, and transparency requirements. This paper briefly reviews models of historical scientific and technological paradigm shifts and describes why the authors believe such a paradigm shift is underway in storage system architectures. The paper describes the requirements to be met, important technical problems being investigated, such as network-connected devices, use of storage hierarchies, and system management, and the characteristics of the emerging large-scale, distributed, storage-architecture paradigm, illustrated with actual implementations and with standards work under way in the IEEE Storage System Standards Working Group.

With increasingly specific inhibitors of lipoxygenases, it becomes possible to more closely define any participation of their biosynthetic products in these events. We cultured chronic myelogenous leukemia cells from the peripheral blood of several patients in blast crisis with three inhibitors of lipoxygenases: ETYA, and the more selective A63162 (Abbott) or SC41661A (Searle). All three agents reduced labelling of DNA with H-3 thymidine measured at 4 h and reduced cell numbers by 72 h. An antisense deoxyoligonucleotide to the 5-lipoxygenase mRNA 'start' codon inhibited DNA synthesis at 24 h, as did two control oligonucleotides. Marked nuclear ultrastructural changes characteristic of apoptosis were induced by SC41661A in a subset of cells with the ultrastructure of promyelocytes. Whether this response characterizes a common pattern of this subset of leukemic cells to SC41661A, if damage to mitochondria with reduced function of bcl-2 protooncogene product located at that site might have contributed or some other mechanism was responsible, and if inhibition of 5-lipoxygenase activity was involved, are questions to be decided in the future.

Each student's performance was represented as a unique arrangement of above average and below average performance for 2, 3, 4, or 5 successively preceding semesters. Following each prediction, subjects were asked to rate how confident they were in their prediction. High confidence was associated with sequences of performance having lower uncertainty, but overestimation of future performance was associated with sequences having high uncertainty. The results were interpreted as supporting a conclusion that there is a positive bias in retrieving similar instances of evidence from memory to bear upon a decision and that the exclusion or reduction of available negative evidence leads to overestimation of future outcomes.

Because of this, scattering problems that can be solved without explicit reference to the state of polarization of the incident and scattered radiation are exceptional. This article reviews available information on polarization effects arising when photons in the X-ray and gamma-ray regime undergo photoelectric effect, coherent (Rayleigh) scattering and incoherent (Compton) scattering by atomic electrons. In addition to descriptions and discussion of these effects, we study the backscattering of gamma-rays from an infinite thickness target excited with a plane slant monodirectional and monochromatic source, using the Boltzmann transport theory and the mathematical representation of polarization introduced by Stokes. Results from this model, for both unpolarized and polarized gamma-ray sources, are compared with computations performed neglecting or averaging polarization effects, showing the limitations of such approximations.

The distributions used are of temperature 0.4-40 K, cubic length 0.003-3.0 cm, and number 10-100 particles. The mutual Coulomb repulsion of the particles causes a reduction in the number of late arrival particles expected from the MB velocity distribution. The Coulomb energy is not equally divided among the particles during the expansion. The energy is transferred preferentially to the outer particles so that the reduction in the number of slow particles is not necessarily large. The reduction factor is found to be greater than unity when the potential energy of the trapped ions is greater than approximately 5 % of the ions' kinetic energy and is approximately 2 for the launch parameters of the Los Alamos antiproton gravity experiment.

This increase can occur without substantial broadening in the collimation of the undulator radiation. We present the spectral properties measured for a tapered 3.3-cm period prototype undulator of the Advanced Photon Source at the Cornell High Energy Synchrotron Source. The width of the on-axis first harmonic at 6.9 keV increased from 0.32 to 0.66 keV for a gap tapering of 12%. Minimal angular broadening in the first harmonic x rays was detected and measurements of off-axis radiation were also performed. The results are found to be in good agreement with model calculations.

We have also calibrated the (angstrom/V) response as a function of voltage up to 220 V at room temperature, imaging a gold-plated diffraction grating. We find that the temperature dependence of the (angstrom/V) response is linear to within 10% and is reduced by a factor of 5.5 on decreasing temperature from 300 to 4.2 K. The near linearity with temperature of the (angstrom/V) response makes the PZT-5A lead zirconate titanate composition a convenient choice for low temperature scanning tunneling microscope piezo tube elements.

A total H- current of approximately 40 mA has been extracted from a 5.6-mm-diam aperture with rf input power higher than 50 kW. Attempts have been made to enhance the H- beam current by introducing a small quantity of cesium vapor into the source chamber. It is found that the H- output current can be increased by a factor larger than 3 if some cesium is applied in the collar around the exit aperture. Electron current can be reduced by cesium deposition on the chamber walls.

The instrument uses seven hollow fibers to transport the radiation by multiple grazing incidence reflections from the tokamak port through the instrument's shield to the spectrometer entrance slit. In this way, the ratio of background radiation streaming through the entrance slit to XUV flux is reduced by a factor of at least 2500. The seven hollow fibers provide seven channels corresponding to seven different lines of sight through the plasma. The spectrograph uses a toroidal mirror together with a plane, aberration-corrected grating to disperse radiation in the 50-200 angstrom region. Up to seven spectra are recorded simultaneously, at rates of 30-90 Hz, using a microchannel plate assembly optically coupled to a charge-coupled device camera. This will permit, during a single discharge, measurement of spatial emissivity profiles from various ionization states of an injected impurity, providing a better understanding of their time evolution and valuable information on cross-field ion transport.

A unique system using a single electrostatic analyzer coupled to a single array of channel electron multipliers allows measurement of the three-dimensional energy per charge distributions of both ions and electrons over E/q ranges from approximately 1 eV/q to > 40 keV/q. Particles selected by the analyzer are post-accelerated into the multipliers to maintain sensitivity for the lowest energy particles. An instrument using this concept called the magnetospheric plasma analyzer (MPA) is described. Presently, three MPAs are in geosynchronous orbits (GEO) aboard spacecraft with International Designators of 1989-046, 1990-095, and 1991-080. The MPA and its response characteristics are described, and examples of on-orbit data showing some of the MPA capabilities are presented. C1 SANDIA NATL LABS,ALBUQUERQUE,NM 87185.

This technique uses optical fibers to couple a probe beam into the reactor volume and requires a minimum of effort to facilitate. Reactor vibrations have a minimal effect on the optical alignment and, consequently, accurate absorption measurements can be made. The technique is illustrated by measurements of radiation-induced absorption in infrasil silica at 1.06, 1.73, and 2.03 mum.

Maritime transportation accidents are relatively common occurrences compared to more frequently analyzed contributors to public risk. Yet research on maritime safety and pollution incidents has not been guided by a systematic, risk-based approach. Maritime shipping accidents can be analyzed using event trees to group the accidents into ''bins,'' or groups, of similar characteristics such as type of cargo, location of accident (e.g., harbor, inland waterway), type of accident (e.g., fire, collision, grounding), and size of release. The importance of specific types of events to each accident bin can be quantified. Then the overall importance of accident events to risk can be estimated by weighting the events' individual bin importance measures by the risk associated with each accident bin.

In this paper, some error analysis issues concerning this method are resolved. The method is shown to be stable and a slightly different stopping criterion for finding the zeroes of the spectral function is suggested. These error analysis results extend to general update methods for the symmetric eigenvalue problem. That is, good backward error bounds are obtained for methods to find the eigenvalues and eigenvectors of A + rhoww(T), given those of A. These results can also be used to analyze a new fast method for finding the eigenvalues of banded, symmetric Toeplitz matrices. C1 OAK RIDGE NATL LAB,OAK RIDGE,TN 37831.

In an earlier work, Manteuffel and Parter [SIAM J. Numer. AnaL, 27 (1989), pp. 656-694] proved that B(h)-1A(h) (A(h)B(h)-1) have a uniformly bounded L2 condition number if and only if A* and B* (A and B) have the same boundary conditions. This earlier work used the H-2 regularity of A and B, as well as optimal L2 error estimates and a quasi-uniform grid for the finite element spaces. In the present paper, we first extend these condition number results to the case in which neither H-2 regularity (and hence optimal L2 error estimates) nor the quasi-uniformity assumption need be satisfied. Instead, it is assumed that the principal part of the preconditioning operator B is a scalar multiple, 1/mu, of the principal part of A. It is also proven in this case that the operators Q = B-1A-muI and Q = AB-1-muI are compact, and the corresponding discrete operators are collectively compact and consistent approximations to Q and Q. Using this, it is shown that the L2 singular values of B(h)-1A(h) and A(h)B(h)-1 ''fill'' the interval [mu0 > mu1] where mu0 > 0 and mu1 are the minimum and maximum values of mu. Moreover, for any epsilon > 0 there are (at most) a finite number, n(epsilon ), of singular values outside the interval [mu0-epsilon+mu1+epsilon]. Analogous results are also proven for the case when B(h)-1 is replaced by a more practical preconditioner, say B(h)-1, which is equivalent to B(h)-1 in the L2 norm. This has important implications for the solution of the preconditioned discrete equations using the conjugate gradient method. In particular, the convergence rate will be better than the usual bound obtained using condition number estimates. Finally, some matrix implementations for both the left and right preconditioned normal equations are discussed in detail. These include implementations that avoid the inversion of the mass matrix.

In order to evaluate these expressions it is necessary to calculate the moments of a bivariate uniform distribution defined over an arbitrary polygon. Expressions for these moments are presented, allowing the mean interpoint squared distance to be used as a measure of spatial clustering. The distribution and power of this test statistic is explored on the unit square, and the spatial distribution of 11 cases of non-Hodgkin's lymphoma is investigated to illustrate an application of the approach.

The specific case of a double-exponential distribution of activation energies (DEDAE), of great importance as a data-analysis model, is discussed in detail for distributed dielectric and intrinsically conducting materials, and important differences in the proper analyses of these systems are particularly emphasized. For both dielectric and conducting distributed systems, two different and important types of temperature response are described and related to earlier work. Model calculations are presented to illustrate frequency and temperature response possibilities for such thermally activated, distributed systems. Various errors in earlier work are corrected, particularly the near-universal identification of theoretical slope parameters appearing in the analysis of exponentially distributed systems with actual measured slopes and power-law exponents. The quite different experimental temperature dependences of the power-law exponents of many dielectric and conductive materials agree qualitatively and often quantitatively with the predictions of the DEDAE response model. Finally, the behavior is briefly discussed of systems which can exhibit wide-range dispersive results simultaneously in both their conductive and dielectric responses.

When molecular rotations are fast, continuous, and complete, the peak-to-peak splitting of motionally averaged spin-1 NMR spectra can depend significantly on the inherent electric field gradient asymmetry, eta, for eta greater-than-or-equal-to 0.05. Parameters describing low-symmetry molecular motion which are extracted from fitting experimental data depend strongly upon eta. One implication of these phenomena is that even the modest electric field gradient asymmetry around deuterons in covalent bonds can contribute considerably to motionally averaged lineshapes, especially when molecular motions are not highly symmetric.

RIMS combines multistep photoionization with mass spectral sorting and detection of the resultant ions to provide high sensitivity and selectivity. The Cr concentration in a NIST standard urine sample has been determined using RIMS/isotope dilution techniques to be 0.093 +/- 0.008 mug/ml in good agreement with the 0.085 +/- 0.006 mug/ml certified value. The results indicate the utility and selectivity of RIMS in isotope dilution analysis of biological samples of complex matrix and history.

The W 4f7/2 feature associated with the clean surface is rapidly attenuated as the sulfur coverage is increased. Two new peaks resulting from the interaction of surface tungsten with the adsorbed sulfur appear. The binding energy of the shifted surface peaks is related to the increased coordination of the first layer tungsten atoms as they bond to the adsorbate and to a chemical shift induced by the sulfur. The intensities of the surface peaks are correlated with the structure of the sulfur overlayer. RP MULLINS, DR (reprint author), OAK RIDGE NATL LAB,OAK RIDGE,TN 37831, USA.

At baseline and following administration of d-amphetamine (a dopamine-releasing drug), GBR-12909 (a potent dopamine reuptake inhibitor), or tetrabenazine (a biogenic amine depleting drug) PET scans of C-11-raclopride binding were obtained in a CTI 931 positron tomograph. In all studies, the ratio of the distribution volumes for the striatum to the cerebellum for C-11-raclopride binding decreased significantly by an average of 16.2% for d-amphetamine, 22.1% for GBR-12909, and 28.3% for tetrabenazine while there were no significant changes observed in the cerebellum or in the rate of systemic metabolism of the radiotracer. These decreases exceed the test/retest variability of striatal C-11-raclopride binding measured in the same animals under identical experimental conditions (Dewey et al., 1992b). Together these studies demonstrate that PET measurements of striatal C-11-raclopride binding can be used to indirectly and non-invasively monitor changes in synaptic dopamine concentrations that result from a variety of neurophysiologic mechanisms.

For a given heat and mass flux that is not too large, there are two possible steady solutions with vapor-liquid counterflow, one liquid-dominated, and one vapor-dominated. Numerical solution of the equations for two-phase vertical counterflow displays intriguing stability behaviour. If pressure and saturation are fixed at depth, and beat and mass flux specified at the top, the vapor-dominated solution is almost always obtained. That is, for a variety of boundary values, the solution settles to the vapor-dominated steady-state, and only for very special values is it possible to obtain the liquid-dominated case. Similarly the liquid-dominated solution is almost always obtained if the boundary conditions are reversed, with pressure and saturation fixed at the top and heat and mass flux specified at depth. This behaviour is here explained in two complementary ways. It is shown to be a consequence of upstream differencing of the flow terms in the numerical method. It is also shown to be expected behaviour for wavelike saturation solutions. Hence the observed behaviour is not only a direct consequence of the numerical method used, but is fundamental to geothermal heat pipes. C1 UNIV AUCKLAND, DES, AUCKLAND, NEW ZEALAND.

One way of treating such effects is through the use of a core-shell effective ionization cross-section (EICS), which depends not only on the property of an isolated atom but also on the dynamical elastic and inelastic scattering and channeling processes of electrons. An experimental method is introduced by which the relative EICS is measured from a thin foil specimen in the transmission case under diffracting conditions equivalent to those in reflection geometry. This is demonstrated in studies of cleaved MgO(100) and MgO(110) surfaces, for which excess oxygen is found on the surfaces. C1 UNIV TENNESSEE,DEPT MAT SCI & ENGN,KNOXVILLE,TN 37996.

The model represents the NAPL as isolated spheres that shrink with dissolution and uses a mass transfer coefficient correlation reported in the literature for dissolving spherical solids. The model accounts for the reduced permeability of a region of residual NAPL relative to the permeability of the surrounding clean media that causes the flowing water to partially bypass the residual NAPL. The dissolution experiments with toluene alone and a benzene-toluene mixture were conducted in a water-saturated column of homogeneous glass beads over a range of Darcy velocities from 0.5 to 10 m d-1. The model could represent the observed effluent concentrations as the NAPL underwent complete dissolution. The changing pressure drop across the column was predicted following an initial period of NAPL reconfiguration. The fitted NAPL sphere diameters of 0.15 to 0.40 cm are consistent with the size of NAPL ganglia observed by others and are the smallest at the largest flow velocity.

Information on the present-day status of fish communities was obtained by the Adirondack Lakes Survey Corporation, which surveyed 1469 Adirondack lakes in 1984-1987 (53% of the total ponded waters in the Adirondack ecological zone). Two hundred and ninety-five of these lakes had been surveyed in 1929-1934 during the first statewide biological survey; 720 had been surveyed in one or more years prior to 1970. Sixteen to 19% of the lakes with adequate historical data appeared to have lost one or more fish populations as a result of acidification. Brook trout and acid-sensitive minnow species had experienced the most widespread effects. Populations of brook trout and acid-sensitive minnows had been lost apparently as a result of acidification from 11% and 19%, respectively, of the lakes with confirmed historical occurrence of these taxa. By contrast, fish species that tend to occur primarily in lower elevation and larger lakes, such as largemouth and smallmouth bass and brown trout, have experienced little to no documented adverse effects. Lakes that were judged to have lost fish populations as a result of acidification had significantly lower pH and, in most cases, also had higher estimated concentrations of inorganic aluminum and occurred at higher elevations than did lakes with the fish species still present. No other lake characteristics were consistently associated with fish population losses attributed to acidification. The exact numbers and proportions of fish populations affected could not be determined because of limitations on the quantity and quality of historical data. Lakes for which we had adequate historical data to assess long-term trends in fish communities were significantly larger and deeper and have higher pH than do Adirondack lakes in general; thus, fish communities adversely affected by acidification and acidic deposition may be underrepresented in this study.

If such a contact is tilted. infiltrating moisture in the fine layer will be diverted and flow down the contact as capillary diversion. Capillary barriers can occur naturally in layered heterogeneous systems. or they can be engineered for the purpose of diverting infiltration, for example, away from hazardous wastes. Recent theoretical analyses of capillary diversion have revealed some simple relations for the behavior of an idealized capillary barrier. Meanwhile, laboratory experiments and field investigations have shown much more complicated behavior. We have attempted to bridge the gap between the simple theoretical results and the more complicated laboratory and field observations by means of numerical experiments. Numerical modeling of capillary barriers presents significant challenges because of the potential for gravitational instability which can give rise to strong space discretization and grid orientation effects. We have examined the ability of different finite difference techniques, such as harmonic weighting, upstream weighting, and higher-order differencing, to represent flow exclusion and leakage effects at capillary barriers. The numerical experiments show that analytical results previously obtained are reasonable, but that leakage occurs upstream of the theoretical breakthrough point. Furthermore, in the breakthrough region and downstream from it, the behavior is considerably more complicated than assumed in the theoretical analysis. Numerical experiments, with careful consideration of space discretization and grid orientation effects, reveal that the initial breakthrough allows sufficient leakage at the contact to partially dry the upper layer, making the barrier active again downstream. Finite difference schemes specifically designed to handle transient multiphase flows can adequately reproduce the broad features of flow diversion and leakage at capillary barriers.

The specimens were water-cooled on the backside and the impact surface of the specimens was at several temperatures from room to the environmental temperature. It was found that the cooled 1018 steel specimens had higher metal wastages than uncooled specimens and that the metal wastages were related to the temperature difference between the environment and the surface of the specimens. With an increasing temperature difference, the E-C metal wastage increased, reaching a maximum at a metal surface temperature of 50-90-degrees-C.

Wetting was obtained by coating the ZrO2 surfaces with Ti prior to brazing by RF sputtering or electron beam evaporation. Braze joints made with Ti-sputter-coated ZrO2 contained high levels of porosity, but those made with Ti coatings deposited by evaporation, referred to as Ti-vapor-coated, contained little or no porosity. Brazing caused the ZrO2 within about 1 mm (0.04 in.) of the joint surfaces to turn black in color, and thermodynamic analysis indicated that the discoloration was likely due to oxygen diffusion out of the ZrO2 into the Ti vapor coating during brazing. Braze joint strength was determined by flexure testing in the four-point bend arrangement, and on a more limited basis, by shear testing. The latter method was used mainly as a screening test for ZrO2-Fe and ZrO2-Ti joints. Flexure testing of ZrO2-ZrO2 and ZrO2-Fe braze joints was done at 25-degrees, 200-degrees, 400-degrees, and 575-degrees-C (77-degrees, 392-degrees, 752-degrees and 1067-degrees-F) in air. For flexure testing, average strengths of joint specimens decreased with increasing test temperature. The lower average strengths of ZrO2-Fe specimens compared to those from ZrO2-ZrO2 joints was attributed to higher residual stresses in the ceramic-to-metal joints. At 25-degrees-C, fracture in the highest strength specimens was associated with considerable failure through the ZrO2 beneath the Ti-vapor-coated surfaces. In contrast, debonding at ZrO2/Ti-vapor-coating interfaces was prevalent in the lower strength specimens at 25-degrees-C, and the tendency for failure to occur by debonding increased with test temperature. The braze filler metal strength did not limit joint strength at temperatures of 400-degrees-C and below. Lapping of the ZrO2 joint surfaces did not improve the strength of ZrO2-Fe joints. Joint strength at 575-degrees-C was limited by the strength of the braze filler metal layers. C1 POHANG STEEL CO,IND SCI & TECHNOL RES INST,POHANG,SOUTH KOREA.

The results are compared with reported data on natural diamond and on graphite. Polycrystalline chemical-vapor-deposited diamond exhibits a spectrum similar to that of natural, single-crystal diamond. Reference is also made to ionization loss spectroscopy in the transmission electron microscope and to near-edge, X-ray absorption fine structure measurements. The prominent features of the measured spectra are correlated with pi and sigma bonding. The applied method is sensitive to pi bonding as well as being surface sensitive and, therefore, is particularly suited to check the deviation from perfect diamond bonding at the surface.

The non-linear phenomena of second-harmonic generation (SHG) and sum frequency generation (SFG) have the potential of probing the surface in situ during diamond CVD. We have initiated a program of investigating the low index planes of the diamond single crystal using conventional surface science techniques in conjunction with SHG and SFG measurements. As a first step in this effort, Auger electron spectroscopy (AES), X-ray photoelectron spectroscopy, spectroscopy and low energy electron diffraction (LEED) temperature-programmed desorption have been used to study the interactions of H and CH(x) species with the reconstructed diamond C(111) (2 x 1) surface. It is found that a very small quantity of chemisorbed H atoms (0.05 ML (monolayer) or less) can induce the (2 x 1)-to-(1 x 1) phase transformation and uphold the sp3 structure up to nearly 1400 K. SHG measurements during the exposure of the surface to hydrogen showed direct correlation with observations by LEED and AES. The vibrational spectrum of the surface hydrogen is obtained using IR visible SFG. On a fully relaxed (1 x 1) surface a single sharp peak at about 2830 cm-1 is observed which can be identified as the CH stretching mode from H on top sites. The SFG spectrum after exposure of the (2 x 1) surface to methane through a hot filament shows the dominant adsorbed species to be the methyl group.

Temporally resolved emission spectra from particulates up to 2 cm from the target and from 10 mus to 1.5 ms after the laser pulse are attributed to blackbody radiation. The spectra are used to estimate temperatures between 2200 and 3200 K for ejecta from both BN and YBCO when irradiated at PHI248 = 3.5 J and 1.5 J cm-2, respectively. The measured cooling of the particles in vacuum is compared to a radiative cooling model. RP GEOHEGAN, DB (reprint author), OAK RIDGE NATL LAB,DIV SOLID STATE,OAK RIDGE,TN 37831, USA.

The misfit dislocations are predominantly dissociated 60-degrees dislocations consisting of 90-degrees and 30-degrees Shockley partial dislocations and enclosed stacking faults. These dissociated 60-degrees dislocations form increasingly asymmetrically on the different {111} glide planes as the misorientation increases. The 90-degrees partial dislocations are not confined to the interface, but lie 0-100 angstrom beneath it. The 30-degrees partial dislocations, in turn, are pushed even further into the substrate.

As the temperature increases, the elastic scattering decreases gradually, to be replaced by quasielastic components. The decrease in elastic intensity occurs not only in the amorphous regions but also in the crystals. In Nylon 6.6 at temperatures 40 K below melting there is practically no elastic scattering intensity left. The experimental observations are compared with NMR and thermal analysis work, that has also indicated large-amplitude motion in Nylon crystals, and are discussed in reference to molecular dynamics simulations on the hexagonal phase of paraffins.

By comparing to exact results in the two-dimensional Ising model we demonstrate that E0a can be extracted very reliably from Monte Carlo calculations in practice. In four dimensions we compare the measured E0a with two different theoretical predictions on the finite-size behavior of the energy splitting. We find that our numerical data are in favor of the predictions based on the semiclassical dilute instanton gas approximation. C1 BROOKHAVEN NATL LAB,DEPT PHYS,UPTON,NY 11973.

The superconducting transition temperatures (in magnetic fields of 0.0-0.4 T) of single crystals prepared by both routes of ET synthesis were found, by the use of ac susceptibility measurements, to be identical within the precision of the measurements (approximately 0.1K or 1%) for the ambient-pressure superconductors kappa-(ET)2Cu(NCS)2 and kappa-(ET)2Cu[N(CN)2]Br. The absence of an effect of such isotopic replacement on T(c) indicates that the central C=C stretching vibration (a high-energy optical mode at approximately 1500 cm-1) is not the dominant contributor to the superconducting pairing mechanism in these systems.
