The addition of TiB2 as a particulate reinforcement to NiAl increases the hardness of the composite with respect to NiAl, and reduces the wear rate at all volume fractions on garnet and Al2O3 abrasives. Abrasion on SiC resulted in a minimum of the wear rate for the composite with 20% TiB2 for most conditions. The composite with 40% TiB2 consistently exhibited wear rates higher than the other composites when abraded on SiC. The only instance when the NiAl-40% TiB2 composite had a lower wear rate was when it was abraded on 16 and 37 mu m SiC particles. The NiAl-TiB2 composite serves as a model system for studying the effect of reinforcement volume fraction on composite wear behavior and is discussed in terms of a composite wear model developed by Axen and Jacobson.

Ti + TiC composites could be sintered to high fractional densities (> 93%), even at high TIC loadings (e.g., 40 volume percent (vol%)). No reactions were observed to occur between the Ti and TiC. By contrast, the Ti and TiB2 and Ti and Si3N4 reacted to form composites consisting of Ti, TiB and TiB2 and alpha-Ti(N), Ti5Si3, Ti3Si, and Ti2N, respectively. As a consequence, Ti was consumed and/or the reaction products intrinsically generated porosity during sintering. These composites were more difficult to consolidate via solid state sintering, particularly at higher volume fractions. Despite the porosity, the composites were more wear resistant (pin-on-drum abrasive wear against 100 mu m garnet particles) than unreinforced Ti, with the exception of the Ti + 2.5 vol% TiB, and Ti + less than or equal to 10 vol% TiC composites. The ranking of microhardness and abrasion wear resistance of the composites was as follows: (hardest, most wear resistant) Ti + Si3N4 (i.e., alpha-Ti(N), +Ti5Si3, Ti3Si, and Ti2N)>> Ti + TiB2 >> Ti + TiC (softest, least wear resistant). The microhardness coupled with the apparent strength of the chemical interface that developed between the constituent composite phases was responsible for the observed wear behavior.

The TIC particles were dispersed in various steel and nickel matrices using a powder metallurgy (P/M) technique. Volume fraction of TiC particles in these composites varied between 0.35 and 0.45. The microstructure of each material was characterized using scanning electron microscopy (SEM), light optical microscopy, and X-ray diffraction (XRD). A high-stress abrasion test (pin abrasion), a low-stress abrasion test (dry-sand/rubber-wheel (DSRW)), an abrasion-impact test (impeller-in-drum) and an erosion test were utilized to understand the wear behavior of these materials under different conditions. While in the low-stress abrasion environment, finer TiC particles (with smaller interparticle spacing) provided better wear resistance, the coarser TiC particles were more effective in protecting the softer matrix from abrasion in the high-stress environment. On the other hand, variation in TiC size did not affect the rate of material loss in the impact-abrasion test. Erosion rate was unchanged with hardness of the composites.

Typical laboratory abrasive wear tests approximate two- and three-body abrasion. The Albany Research Center, however, uses a suite of four laboratory abrasion, gouging-abrasion, and impact-gouging abrasion wear tests to rank materials for wear applications in the mining and minerals processing industries. These tests, and the wear mechanisms they approximate, are: (1) dry-sand, rubber-wheel (three-body, low-stress abrasion); (2) pin-on-drum (two-body, high-stress abrasion); (3) jaw crusher thigh-stress gouging-abrasion); and (4) high-speed, impeller-tumbler (impact-abrasion). Subsequently, candidate materials can be ranked according to their performance for each of the wear tests. The abrasion, gouging-abrasion, and impact-abrasion test methods are described, highlighting the predominant wear mechanisms for each test. Data an a wide variety of irons and steels are presented with relative ranking of the materials according to the specific wear test. (C) 1999 Published by Elsevier Science S.A. All rights reserved.

But in fact, high-alumina ceramics are available in a wide range of compositions, both in terms of alumina content and grain-boundary chemistry, and this variation in composition can have an important influence on the wear behavior of the material. In this study, the effect of composition and microstructure on the two-body abrasive wear behavior of a series of high-alumina ceramics containing between 85 and 99.997% alumina is examined. Results indicate that in order to optimize abrasive wear resistance, the alumina grain size should be small, regardless of the alumina content. In addition, if second phases are present at the boundaries, they should be amorphous, with a composition high in alkaline earth constituents to reduce their softening point. Comparisons of the wear behavior of the polycrystalline aluminas with a single crystal sapphire under identical test conditions indicate that the presence of grain boundaries enhances the wear resistance of alumina regardless of alumina content, so long as the matrix grain size remains small.

A second, less commonly used tool is field wear testing. Field wear testing, while being more time-consuming, has the advantage that the materials are exposed to the actual environmental conditions and abrasives responsible for the wear loss. This paper examines four different abrasive wear tests (pin-on-drum, dry-sand rubber-wheel, jaw crusher, and impeller-in-drum), and compares the results obtained from these tests with field wear tests using the Albany Research Center's Planar Array Field wear test. A variety of ferrous-based alloys commonly used to resist abrasion in the mineral processing industry were tested, including carbon steels, low alloy steels, austenitic steels, and white cast iron.

Committee G-2 on 'Wear and Erosion' was established in 1964 and has been a leader in developing such standards. Some ASTM wear testing standards are aimed at specific components, like the jaws of rock crushers, but others are designed to determine a material's resistance to a specific wear type, like solid-particle erosion or two-body abrasive wear. Having identified a need for a new wear testing standard, ASTM G-2 typically follows a process of first assigning responsibility to a relevant subcommittee. The subcommittee chair may then decide to establish a task group to develop the given method, conduct one or more inter-laboratory testing programs, write a draft standard, conduct ballots, and revise or rewrite the draft standard to achieve consensus. Since the repeatability and reproducibility varies between test methods, understanding the role of instrumental and measurement factors of each wear testing standard is critical before it can become approved. In addition, each standard is critically reviewed on a continuing 5-year basis, and revised or updated as needed. This paper describes the development of standard wear testing methods and provides five examples of how ASTM G-2 wear testing standards were used to help solve important industrial problems involving sliding wear, abrasive wear, galling, and erosive wear.

The apparatus is similar to the one first developed by Bond; however, in the apparatus used at the Albany Research Center, three paddles instead of just one are situated in the drum which can be impacted and abraded during the course of the wear test. In using three paddles, a standard can be run at the same time as the specimens of interest. Two test procedures have been developed which provide information on the relative resistance of a material to the combined action of impact and abrasion. In the first procedure, the wear samples are run for 1 h on each side of the specimen paddle. This average value of the two tests gives an upper average limit to the impact-abrasive wear of the material, but has the advantages of being easy to run and relatively quick. The second procedure attempts to determine the steady-state wear behavior by running sequential wear tests on one surface of the specimen paddle. In this procedure, anywhere from three to five l-h tests are run on one surface of the paddle. The cumulative mass or volume loss is plotted as a function of time and the slope of the linear portion of the curve provides the value for the steady-state wear rate. In addition to describing the experimental procedure, wear mechanisms will be discussed and the changes that occur in the microstructure as a result of the wear tests will also be described. The way various alloys behave in pure abrasion and in impact-abrasion will be discussed, highlighting the change in a material's wear behavior with a change in wear mode.

The purpose of this work was to ascertain whether the latter ceramic composite would produce a beneficial lubricating film on the opposing surface and serve as a self-lubricating material. Type 440C stainless steel was used as the counterface material. Machining practices were selected to provide the surface roughness and lay (direction of grinding marks) similar to that of actual valve guide bores. For comparison with the ceramic composite material, both cast iron and silicon nitride matrix materials were also tested. Tests were also performed using graphite powder on the silicon nitride matrix material to ascertain what frictional behavior might be observed in the most favorable case. Friction and wear data, combined with surface chemical analysis confirmed that the current composite, while wear resistant, did not provide any lubrication advantages over silicon nitride itself. No evidence for the sliding-induced formation of a beneficial graphite film was obtained by optical examination, scanning electron microscopy, or surface chemical analysis. While the type of graphite used in the present composite fractured into fine particles and did not form a lubricating film in our experiments, the results do not preclude the possibility of developing other ceramic composites with self-lubricating properties.

A three-dimensional ray tracing model considers the effect of laser parameters, joint geometry and material reflectivity to predict the location of energy absorption and the onset of melting. Focal spot location changes and F number changes, corresponding to a matrix of experimental conditions, are used as input to a series of simulation runs. Experimental data are used to define the location of the onset of melting in 304 stainless steel and to verify the energy density threshold of melting predicted from simulation results. Melt patterns, produced by single Nd:YAG laser pulses, on the joint groove faces are analyzed and compare well with calculation and simulation results. The results of this study provide quantitative experimental validation of this model that can be used to understand and apply fundamental principals of nonimaging optics for enhanced laser processing.

Test joints were processed at, or below, 450 degrees C (842 degrees F) to assure meeting minimum base metal yield strength requirements. Creep and tensile properties of the bulk filler metal candidates, including a gold-indium alloy, were measured. A constitutive model, based on the Garofalo sinh equation, was developed from the creep data for use in predicting residual stresses in actual joints. Wetting behavior, interfacial reactions and joint microstructures were investigated, with samples processed in a vacuum between 400 to 550 degrees C. Prototype joints were tested in shear. The Au-12Ge filler metal offered the best alternative to the higher melting braze alloys. The alloy exhibited excellent wetting and creep behavior, with low contact angles, generally less than 20 deg, and good creep relaxation under typical loading conditions.

At room temperature the observed space group is Fmmm, although then is reason to believe that at a finer level of distinction it is really Cmcm approximating Fmmm. The nickel center lies on a site of apparent point symmetry mmm. At lower temperatures, the space group is unambiguously Cmcm without appreciable change in the unit cell parameters. and the molecule lies at a site of m2m symmetry. The shape of the molecule changes smoothly with temperature variations from room temperature down to about 140 K, in a behavior characteristic of second-order phase transformations. The molecular shape varies, but by lesser amounts, below 140 K. Possible causes of this phenomenon are discussed. The increase in intensity on cooling of some of the bands observed in the polarized crystal spectrum of the complex is consistent with the change in the molecular structure. Bonding parameters derived from the transition energies indicate that the cyanurate produces a very weak ligand field, which is consistent with the long metal-ligand bond to this ligand. The magnetic properties of the solid display Curie-Weiss behavior through the temperature range of the most pronounced molecular shape changes, but antiferromagnetic interactions become significant below 50 K, with antiferromagnetic ordering at 2.61 K. The propagation pathways for the magnetic interactions are inferred. C1 Univ Zaragoza, CSIC, Dept Inorgan Chem, E-50009 Zaragoza, Spain.

Matrix-free (iterative) solution algorithms such as non-linear conjugate gradients (CG) and dynamic relaxation (DR) are desirable for large solid mechanics applications where direct linear equation solving is prohibitively expensive, but in contrast to more traditional Newton-Raphson and quasi-Newton iteration strategies, the number of iterations required for convergence is typically of the same order as the number of degrees of freedom of the model. It is therefore crucial that each of these iterations be inexpensive to perform, which is of course the essence of a matrix free method. In applying such methods to contact problems we emphasize here two requirements: first, that the treatment of the contact should not make an average equilibrium iteration considerably more expensive; and second, that the contact constraints should be imposed in such a way that they do not introduce spurious energy that acts against the iterative solver. These practical concerns are utilized to develop an iterative technique for accurate constraint enforcement that is suitable for non-linear conjugate gradient and dynamic relaxation iterative schemes.

By using an off-stoichiometric ratio (1.2 moles of silicon), Ti3SiC2 with a purity of better than 98 vol.% was synthesized. The synthesized materials were annealed at 1600 degrees C and 1800 degrees C for up to 10 h to verify its chemical stability at high temperatures. The ternary compound was found to be stable at temperatures as high as 1800 degrees C under an argon atmosphere. Dense compacts of Ti3SiC2 were obtained by hot pressing of reactively sintered compacts. The oxidation behavior of the ternary compound was investigated in air at 1000 degrees C and found to be paralinear. (C) 1999 Elsevier Science S.A. All rights reserved.

The two types of molecules are active toward several organic liquids, gelling in some cases at w/w percentages as low as 0.1. While relatively robust, macroscopically "dry" gels are formed in several cases, studies with a variety of probes indicate that much of the solvent may exist in domains that are essentially liquid-like in terms of their microenvironment. The gels have been imaged by atomic force microscopy and conventional and fluorescence microscopy, monitoring both the gelator fluorescence in the case of the stilbene-cholesterol gels and, the fluorescence of solutes dissolved in the solvent. Remarkably, our findings show that several of the gels are composed of similarly appearing fibrous structures visible at the nano-, micro-, and macroscale.

Much of our knowledge concerning contaminant-mineral interactions at the molecular level, however, is derived from extensive experimentation on model mineral systems. Although these investigations have provided a foundation for understanding reactive surface functional groups on individual mineral phases, the information cannot be readily extrapolated to complex mineral assemblages in natural systems. Recent studies have elucidated the role of less abundant mineral and organic substrates as important surface chemical modifiers and have demonstrated complex coupling of reactivity between permanent-charge phyllosilicates and variable-charge Fe-oxohydroxide phases. Surface chemical modifiers were observed to control colloid generation and transport processes in surface and subsurface environments as well as the transport of solutes and ionic tracers. The surface charging mechanisms operative in the complex mineral assemblages cannot be predicted based on bulk mineralogy or by considering surface reactivity of less abundant mineral phases based on results from model systems. The fragile nature of mineral assemblages isolated from natural systems requires novel techniques and experimental approaches for investigating their surface chemistry and reactivity free of artifacts. A complete understanding of the surface chemistry of complex mineral assemblages is prerequisite to accurately assessing environmental and human health risks of contaminants or in designing environmentally sound, cost-effective chemical and biological remediation strategies.

They are also used as lubricants in petroleum extraction and as industrial catalysts for the synthesis of many organic compounds. These applications derive fundamentally from the colloidal size and permanent structural charge of clay mineral particles, which endow them with significant surface reactivity, Unraveling the surface geochemistry of hydrated clay minerals is an abiding, if difficult, topic in earth sciences research. Recent experimental and computational studies that take advantage of new methodologies and basic insights derived from the study of concentrated have begun to clarify the structure of electrical double layers formed on hydrated clay mineral surfaces, particularly those in the interlayer region of swelling 2:1 layer type clay minerals. One emerging trend is that the coordination of interlayer cations with water molecules and clay mineral surface oxygens is governed largely by cation size and charge, similarly to a concentrated ionic solution, but the location of structural charge within a clay layer and the existence of hydrophobic patches on its surface provide important modulations, The larger the interlayer cation, the greater the influence of clay mineral structure and hydrophobicity on the configurations of adsorbed water molecules, This picture extends readily to hydrophobic molecules adsorbed within an interlayer region, with important implications for clay-hydrocarbon interactions and the design of catalysts for organic synthesis.

A complex variety of abiotic and biotic processes affects their speciation and distribution, including adsorption onto and desorption from mineral surfaces, incorporation in precipitates or coprecipitates, release through the dissolution of minerals, and interactions with plants and microbes. Some of these processes can effectively isolate heavy metals from the biosphere, whereas others cause their release or transformation to different species that may be more (or less) bioavailable and/or toxic to organisms. Here we focus on abiotic adsorption and precipitation or coprecipitation processes involving the common heavy metal contaminant lead and the metalloids arsenic and selenium in mine tailings and contaminated soils. We have used extremely intense x-rays from synchrotron sources and a structure-sensitive method known as x-ray absorption fine structure (XAFS) spectroscopy to determine the molecular-level speciation of these elements at concentrations of 50 to several thousand ppm in the contaminated environmental samples as well as in synthetic sorption samples. Our XAFS studies of As and ph in the mine tailings show that up to 50% of these contaminants in the samples studied may be present as adsorbed species on mineral surfaces, which makes them potentially more bioavailable than when present in sparingly soluble solid phases. Our XAFS studies of Se(VI) sorption on Fe2+-containing sulfates show that this element undergoes redox reactions that transform it into less bioavailable and less toxic species, This type of information on molecular-level speciation of heavy metal and metalloid contaminants in various environmental settings is needed to prioritize remediation efforts and to assess their potential hazard to humans and other organisms.

By using DNA as a rigid spacer, a series of constructs with varying intramolecular donor-acceptor spacings were used to measure the mean and distribution width of fluorescence resonance energy transfer (FRET) efficiencies as a function of distance. The mean single-pair FRET efficiencies qualitatively follow the distance dependence predicted by Forster theory. Possible contributions to the widths of the FRET efficiency distributions are discussed, and potential applications in the study of biopolymer conformational dynamics are suggested. The ability to measure intramolecular (and intermolecular) distances for single molecules implies the ability to distinguish and monitor subpopulations of molecules in a mixture with different distances or conformational states. This is demonstrated by monitoring substrate and product subpopulations before and after a restriction endonuclease cleavage reaction. Distance measurements at single-molecule resolution also should facilitate the study of complex reactions such as biopolymer folding. To this end, the denaturation of a DNA hairpin was examined by using single pair FRET. C1 Univ Calif Berkeley, Lawrence Berkeley Lab, Div Sci Mat, Berkeley, CA 94720 USA.

This occurs even with perfectly homogeneous In distribution (i.e., no clustering). This unusual effect can explain simultaneously exciton localization and a large, composition-dependent band gap bowing coefficient in InGaN alloys. This is in contrast to conventional alloys such as InGaAs that show a small and nearly composition-independent bowing coefficient. We further predict that (i) the hole wave function localization dramatically affects the photoluminescence intensity in InGaN alloys and (ii) the optical properties of InGaN alloys depend strongly on the microscopic arrangement of In atoms.

In these latter cases, partial microcrystallinity develops as the films are grown thicker (1.5-2.5 mu m) and this is accompanied by sharp drops in solar cell open circuit voltage. For the fully amorphous films, x-ray diffraction (XRD) shows improved medium-range order compared to undiluted films and this correlates with better light stability. Capacitance profiling shows a decrease in deep defect density as growth proceeds further from the substrate, consistent with the XRD evidence of improved order for thicker films.

The chloride ligands can be exchanged with either Me3SiBr or Me3SiI to give the uranium metallocene bromides or iodides. The fluorides were prepared by the reaction of BF3. OEt2 with Cp "U-2(NMe)(2), Cp double dagger(2)U(OMe)(2), or Cp double dagger(2)UMe(2). The crystal, structures of Cp "2UCl2, Cp double dagger(2)UCl(2), Cp "2UMe2, Cp double dagger(2)UF(2), and dimeric (Cp "2UF2)(2) are reported. The idealized symmetry of the monomers Cp "2UX2 and Cp double dagger(2)UCl(2) is C-2v when X is F, Cl, or Br and C-2 when X is I or Me; in the dimer, the idealized symmetry is C-i. This preference is rationalized by intramolecular and intermolecular steric effects. The solution ring conformations and intramolecular exchange processes have been studied by variable-temperature H-1 NMR spectroscopy. In all cases, the low-temperature limiting spectra are consistent with the idealized symmetry observed in the solid state.

At low temperature, the number of inequivalent CMe3 or SiMe3 groups implies that the solution structure is the same as the solid-state structure in all of these complexes. The barriers to ring rotation in the Cp" series are strongly dependent upon the U-X distance, but all of the barriers to ring rotation in the Cp" series are the same. The trends in ring rotation barriers are explained by the different conformations of the Cp ligands in the dimers.

Above room temperature, the halide atoms exchange sites rapidly on the NMR time scale. C1 Univ Calif Berkeley, Dept Chem, Berkeley, CA 94720 USA.

The measured muon flux is [1.74 +/- 0.07(stat) +/- 0.02(sys)] x 10(-13) cm(-2) s(-1) sr(-1) compared to an expected flux of [1.97 +/- 0.44(theor)] x 10(-13) cm(-2) s(-1) sr(-1). The absolute measured flux is in agreement with the prediction within the errors. However, the zenith-angle dependence of the observed upward throughgoing muon flux does not agree with no-oscillation predictions.

We calculate the ideal shear strengths of Al and Cu at zero temperature using pseudopotential density functional theory within the local density approximation. These calculations allow for structural relaxation of all five strain components other than the imposed shear strain and result in strengths on {111} planes of 1.85 and 2.65 GPa for Al and Cu, respectively (8%-9% of the shear moduli). In both Al and Cu, the structural relaxations reduce the ideal shear strengths by 35% to 45%, but the directions of relaxation strain in each are qualitatively different. [S0031-9007(99)08769-4].

Examples of application to the simulation of electron energy loss, radiation emission induced by fast electrons, and light scattering are offered. Large rates of Smith-Purcell radiation are predicted in the interaction of fast electrons with strings of Al and SiO2 spheres, suggesting its possible application in tunable soft UV light generation.

The electron-ion recombination process, including resonant and non-resonant recombination may be unified as a natural extension of the coupled-channel approximation, as traditionally employed for photoionization and electron-ion scattering. Recombination cross sections can be calculated to the same accuracy by employing similar eigenfunction expansions for the target ion. Detailed results are obtained for electron recombination with C v, C VI, O VIII and Fe XXV. Several sets of theoretical calculations are reported and discussed: non-relativistic CC in LS coupling, relativistic CC in the Breit-Pauli approximation, with radiative attenuation and fine structure, and the relativistic distorted-wave approximation. The theoretical results are in very good agreement with highly accurate experimental measurements at the Heidelberg test storage ring for CV, CVI and OVIII, and the electron-ion beam trap at Livermore for Fe XXV. We discuss the overall effect of radiation damping of all resonances on effective cross sections and rates, important for H- and He-like ions. In addition to agreement with experimental data, the validity of the CC calculations is demonstrated by the continuity between the calculated photorecombination, dielectronic recombination and electron impact excitation cross sections. Certain issues related to the works of Badnell et al (1998 J. Phys. B: At. Mel. Opt. Phys. 31 L239) and Robicheaux (1998 J. Phys. B: At. Mel. Opt. Phys. 31 L109) are also addressed.

Two scaling regimes are found in the sense that two distinct power laws, k(-beta), are needed to represent the wavenumber spectrum E(k) over the full range of scales r approximate to 1/k. Detailed numerical simulations show that the scale break at 2-5 m is not traceable to the normal variability of LWC in the PVM's instantaneous sampling volume (1.25 cm(3)) driven by Poissonian fluctuations of droplet number and size. The two regimes therefore differ physically. The non-Poissonian character of the small-scale LWC variability is consistent with a similar finding by Baker [1992] for droplet number concentration obtained from Forward Scattering Spectrometer Probe (FSSP) data: at scales of a few centimeters, spatial droplet distributions do not always follow a uniform Poisson law. With beta = 0.9 +/- 0.1, the small-scale (8-12 cm less than or similar to r less than or similar to 2-5 m) regime is stationary: jumps in LWC are highly variable in size and rapidly cancel each other, leading to short-range correlations. By contrast, the large-scale (5 m less than or similar to r less than or similar to 2 km) variability with beta = 1.6 +/- 0.1 is nonstationary: jumps are generally quite small, conveying a degree of pixel-to-pixel continuity and thus building up long-range correlations in the low-pass filtered signal. The large-scale structure of the complex SOCEX cloud system proves to be multifractal, meaning that large jumps do occur on an intermittent basis, that is, on a sparse fractal subset of space. Low-order, hence more robust, multifractal properties of the SOCEX clouds are remarkably similar to those of their First ISCCP Regional Experiment (FIRE) and Atlantic Stratocumulus Transition EXperiment (ASTEX) counterparts, and also to those of passive scalars in fully developed turbulence. This is indicative of a remarkable similarity in the microphysical and macrophysical processes that determine cloud structure in the marine boundary layer at very remote locales, especially since the particular SOCEX cloud system investigated here was rather atypical. Interesting differences are also found: in the scaling ranges on the one hand, and in higher-order moments on the other hand. Finally, we discuss cloud-radiative effects of the large- and small-scale variabilities. C1 Los Alamos Natl Lab, Space & Remote Sensing Sci Grp, Los Alamos, NM 87545 USA.

To facilitate intercomparison, we compute from the reanalyses and radiosonde data deep layer temperatures equivalent to those estimated from the satellite-based Microwave Sounding Unit (MSU). Equivalent MSU temperatures generated using global mean weighting functions and a radiative transfer code give similar results. NCEP's pre-1979 global mean lower stratospheric temperature anomalies diverge markedly from radiosonde data. A smaller offset occurs in the midtroposphere. These differences are attributed to a likely warm bias in the tropical lower stratosphere in the temperature retrievals used by NCEP from November 1978 onward, and changes in the error characteristics of the assimilation model's simulation of the lower stratosphere. In the lower troposphere, ERA and NCEP show different global mean trends due to differences in assimilation strategy, input observational data, quality control procedures, and model physics. Over 1979-1993, ERA warms by 0.106 degrees C/decade, while NCEP cools by 0.028 degrees C/ decade. Applying the HadRT1.1 (radiosonde) data availability mask to NCEP improves the agreement between these data sets. Neglecting coverage differences can yield misleading results in MSU-radiosonde trend comparisons. Substantial trend uncertainties also arise from coverage differences between various radiosonde data sets. Version c of the MSU lower tropospheric temperature retrieval fails to adjust explicitly fur orbital decay. If this were applied without any additional adjustments, it would resolve an important discrepancy: in MSUc the lower troposphere has cooled in relation to the midtroposphere, while the reverse is the case for both reanalyses and for the radiosonde data examined here.

To further examine their usefulness for climate studies and the impacts that different physical parameterizations have on the simulations, an intercomparison experiment has been performed where three regional climate models are used to simulate an extreme flood event. Although the dynamical components of the models are almost identical, the physical parameterizations used to represent clouds, radiative transfer, turbulence transport, and surface processes are very different. The models were used to simulate the heavy precipitation during the 1991 summer which caused severe flooding over the Yangtze River in China. This extreme event is selected to highlight the differences among regional climate models. Results from the intercomparison show that all models simulated the gross flood conditions reasonably well, although each model reproduced the observed rainband to varying degrees, and significant differences are found in the simulated energy and hydrological cycles, especially over cloudy areas. Through detailed analyses of model simulations at different spatial and temporal scales, several reasons are found to cause the departure of model simulations from each other. These include the simulation of the amount and vertical distribution of clouds, the treatment of cloud-radiative feedbacks, and the representation of land surface processes. This study suggests that aspects other than surface temperature and precipitation of the regional climate simulations need to be more carefully evaluated. One specially important evaluation criterion is the radiation balance which has serious implications for long-term climate simulations. C1 Pacific NW Natl Lab, Richland, WA 99352 USA.

While the excitation energies of Rydberg states computed by TDDFT are significantly inferior to the results of Hartree-Fock-based single excitation theories, TDDFT performs slightly better than the HF-based theories for valence states with dominant single excitation character. For valence states with substantial double excitation character, TDDFT is a striking improvement over the HF-based theories, the latter being qualitatively incorrect descriptions for these states.

These were termed as PAF: lysoplasmalogen (lysophospholipid) transacetylase and PAF:sphingosine transacetylase, respectively. In the present study, we have solubilized and purified this PAF-dependent transacetylase 13,700-fold from rat kidney membranes (mitochondrial plus microsomal membranes) based on the PAF:lysoplasmalogen transacetylase activity. The mitochondria and microsomes were prepared and washed three times, then solubilized with 0.04% Tween 20 at a detergent/protein (w/w) ratio of 0.1. The solubilized fractions from mitochondria and microsomes were combined and subjected to sequential column chromatographies on DEAE-Sepharose, hydroxyapatite, phenyl Sepharose, and chromatofocusing. The enzyme was further purified by native-polyacrylamide gel electrophoresis (PAGE) and affinity gel matrix in which the competitive inhibitor of the enzyme, 1-O-hexadecyl-2-N-methylcarbamyl-sn-glycero-3-phosphoethanolamine was covalently attached to the CH-Sepharose. On SDS-PAGE, the purified enzyme showed a single homogeneous band with an apparent molecular mass of 40 kDa. The purified enzyme catalyzed transacetylation of the acetyl group not only from PAF to lysoplasmalogen forming plasmalogen analogs of PAF, but also to sphingosine producing N-acetylsphingosine (C(2)-ceramide). In addition, this enzyme acted as a PAF-acetylhydrolase in the absence of lipid acceptor molecules. These results suggest that PAF dependent transacetylase is an enzyme that modifies the cellular functions of PAF through generation of other diverse lipid mediators.

Stopping rules are described for pure random search and stratified random search. These stopping rules use an estimate of the probability measure of the epsilon-close points to terminate these algorithms when a specified confidence has been achieved. Numerical results indicate that these stopping rules require fewer samples and are more reliable than the previous stopping rules for these algorithms. These stopping rules can also be applied to multistart local search and stratified multistart local search.

It incorporates major experimental findings in direct and photoinduced optical absorption, in stimulated photoemission and photoconductivity. Our theoretical picture is based upon a band description for electronic states, while invoking corrections from Coulomb interactions. We demonstrate the existence of different types of Coulomb excitons and their roles in optical absorption. We show that a low binding energy-emitting exciton also dominates in the fundamental absorption. Contradictions in the current modeling state-of-the-art are displayed and discussed. For poly(phenylene vinylene) (PPV)-type polymers, we give new assignments for the most disputed features; for oligomers we identify new ones as edge states. In applying our model to the poly(phenylene) (PPP) family, more progress is available due to analytical results covering not only spectra but also the oscillator strength. We conclude similar assignments as for PPV and emphasize the delocalized nature of basic features. An important and intriguing peculiarity of PPP- compared with PPV-based polymers is the possible level inversion between excitons. Comparison is made to available optical and electron energy loss spectroscopy (EELS) data. Our conclusions are suggestive for future light-polarized experiments. (C) 1999 Elsevier Science S.A.

Adhesion of these films to silicon substrates was very high, and was achieved by atomically mixing the film and the Si at the interface. The deposition of the tungsten-doped amorphous carbon films was carried out at room temperature, and the energy of the depositing ions was in the range of 100-6 keV. The films were characterized by TEM, XRD, XPS, RES and Raman spectroscopy. Small additions of W to amorphous carbon significantly decrease the magnitude of the compressive stresses that are present in these films. The corresponding decrease in hardness with increasing W content was not nearly as significant. Film hardness varied between 63 GPa (with 1 at.% W) and 20 GPa (the bulk value for WC) and depended not only on the W content but also on the depositing ion energy. At W contents between 20 and 50 at.%, the film consisted of crystalline WC dispersed in an amorphous C matrix. At W content below 20 at.%, the WC present in the film was amorphous, and the film consisted then of mixtures of a-WC and a-C. (C) 1999 Elsevier Science S.A. All rights reserved.

The experimental results were obtained from electrochemical impedance spectroscopy, quartz crystal microbalance (QCM and EQCM) studies, and current-potential characteristics. The theoretical work involved calculating the adsorption energy and molecular configuration of the cobaltocenium accepters at the GaAs surface using high level density functional theory (B3LYP and variations thereof) as well as semiempirical methods. The QCM experiments showed that both Co(Cp)(2)(+) and Co(Cp)(2)(0) are physisorbed at GaAs surfaces, with adsorption energies of about 0.2 and 0.4 eV, respectively. The theoretical results are consistent with these experimental results. They indicate that adsorption of the Co(Cp)(2)(+/0) redox system occurs on GaAs, with Co(Cp)(2)(0) somewhat more strongly adsorbed than Co(Cp)(2)(+); the Co(Cp)(2)(+/0) molecules were found to adsorb with the cyclopentadienyl rings parallel to the GaAs surface. A model for the overall electron-transfer process was developed that incorporates Co(Cp)(2)(+) adsorption. Analysis of the detailed impedance spectra over the range of 1 Hz to 600 kHz showed that the sequential electron-transfer steps in the model (i.e., electron transfer from the: GaAs conduction band to adsorbed Co(Cp)(2)(+), followed by electron transfer from the adsorbed Co(Cp)(2)(0) to free Co(Cp)(2)(+) in solution) are very fast and that the observed overall rate of electron transfer is limited by the rate of thermionic emission from the GaAs bulk region to the: surface. The implications of these results for the theory of electron transfer at semiconductor-liquid interfaces, and the associated controversies surrounding theory and various experimental results for GaAs-metallocenium systems, are discussed.

The rod formation was observed using small-angle neutron scattering (SANS). The diameter of the rods was determined to be 43.2 +/- 1.6 Angstrom, the same diameter as unassembled TiO2 particles. The rod diameter was found to be independent of TiO2 concentration or pH, while rod length was sensitive to both. An independent determination of the molecular weight per unit length of a rod using SANS confirms the beadlike structure of the rods with a bead diameter of 40 +/- 3 Angstrom. Further confirmation of self-assembly was obtained from transmission electron microscopy where long rods with a diameter of 42.8 +/- 3.5 Angstrom were observed. The formation of rodlike structures was not detected when the mercapto group was either blocked by a methyl group or separated from the carboxyl group with an additional methylene group. The self-organization of TiO2 particles in rodlike structures was fund to be a consequence of the special conformations of surface modifiers upon bidentate: binding of mercapto-carboxylic acids. These special bidentate bindings introduce conformations of surface modifiers that allow a significant increase of a dipole moment at the surface. Single-point ZINDO calculations suggest a change of the dipole moment from 1.5 D for unbound thiolactic acid to 11.2 D for bidentate bound thiolactate surface Ti atoms.

Changes in the absorption spectra that occur continuously throughout this range may reflect increased extent of coordination of the central Mg, changes in solvent dielectric, and/or altered hydrogen bonding. Fluorescence emission spectra exhibit a new feature that grows steadily, beginning at temperatures below about 250 K in solvents that are hydrogen-bond donors: 1-propanol and 2-propanol. The emerging fluorescence band, located about 300 cm(-1) to the blue of the fluorescence band seen at higher temperatures, achieves nearly equal amplitude at 163 K and below. It is noteworthy that no corresponding feature appears in the absorption on the blue side of the Q(y) absorption band. The Kennard-Stepanov relation between absorption and fluorescence, which holds with somewhat elevated T* values in the high-temperature region, is seen to fail dramatically at lower temperatures as the short-wavelength fluorescence feature grows. The short-wavelength feature is interpreted as fluorescence resulting from an excited electronic state that is conformationally unrelaxed. At temperatures below 178 K evidence for additional spectroscopic features appears, especially in conjunction with measurements of emission spectra using different excitation wavelengths and of excitation spectra of fluorescence measured at different emission wavelengths. This is in the region of matrix glass formation, and the new BChl a components may reflect site inhomogeneity. Similar spectroscopic studies of BChl a in non-hydrogen-bonding solvents do not provide evidence of new blue-shifted fluorescence in the 298-79 K temperature range. They do, however, exhibit evidence of site inhomogeneity in the low-temperature glass matrices. Implications are discussed regarding the interpretation of low-temperature spectral features that have been reported for photosynthetic membranes and isolated pigment-proteins.

Since these 2Fe-2S complexes contain both terminal thiolates and bridging sulfides, contributions to covalency from both sets of ligands can be evaluated. Importantly, the pre-edge feature of sulfide can be resolved from that of thiolate due to differences in effective nuclear charge. In our previous studies, the covalency of the metal-thiolate bond in [Fe(SR)(4)](-) was determined. In this study, sulfide covalency is quantified for the first time on the basis of an analysis of previous X-ray photoelectron and X-ray absorption spectroscopic studies of [FeCl4](-) which are then applied to the bis-mu(2)-sulfide compound KFeS2. With references for both sulfide and thiolate covalencies thus established for open d-shell systems, comparisons are made between thiolate and sulfide bonding. Sulfide-Fe covalency in the [Fe2S2(SR)(4)](2-) complexes is higher than thiolate-Fe covalency, indicating extensive charge donation of the bridging sulfides. Finally, this investigation of model complexes is extended to the oxidized and reduced 2Fe-2S cluster of the Rieske protein of Paracoccus denitrificans which has terminal thiolates on one Fe center, and histidines on the other Fe center. It is determined that thiolate covalency of the Fe(III) center is the same in both the oxidized and reduced Rieske clusters and similar to that of the [Fe2S2(SR)(4)](2-) model complexes. Further, in the fully oxidized Rieske cluster, the sulfide covalency of the ferric center containing terminal histidine ligation is similar to 18% higher than the Fe(III) containing terminal thiolate ligation. This is consistent with the fact that the histidine ligands are poorer donors and supports the suggestion that the terminal histidine ligation makes a significant contribution to the higher reduction potential of the Rieske protein.

The kinetic model used includes all reactions of (OH)-O-., O-.(2)-, and reactive nitrogen species known to be important under the prevailing conditions; because the rate constants for all of these reactions have been independently measured, the calculations contain no adjustable fitting parameters. The model quantitatively accounts for (1) the complex pH dependence of the O-2 yields and (2) the unusual effects of NO2-, which inhibits O-2 formation in neutral, but not alkaline, solutions and also reverses inhibition by organic (OH)-O-. scavengers in alkaline media. Other observations, including quenching of O-2 yields by ferrocyanide and bicarbonate, the pressure dependence of the decomposition rate, and the reported dynamic behavior for O-2 generation in the presence of H2O2, also appear to be in accord with the suggested mechanism. Overall, the close correspondence between observed and calculated O-2 yields provides strong support for decomposition via homolysis of the ONOOH peroxo bond.

Examples of enzymes containing Cu, Mn, and Fe as the redox-active metal have been characterized. Recently, a SOD containing one Ni atom per subunit was reported. The amino acid sequence of the NiSOD deduced from the nucleotide sequence of the structural gene sodN from Streptomyces seoulensis is reported and has no homology with other SODs. X-ray absorption spectroscopic studies coupled with EPR of the Ni center show that the Ni in the oxidized (as isolated) enzyme is in a five-coordinate site composed of three S-donor ligands, one N-donor, and one other O- or N-donor. This unique coordination environment is modified by the loss of one N- (or O-) donor ligand in the dithionite-reduced enzyme. The NiSOD activity was determined by pulse radiolysis, and a value of k(cat) = 1.3 x 10(9) M-1 s(-1) per Ni was obtained. The rate is pH sensitive and drops off rapidly above pH 8. The results characterize a novel class of metal center active in catalyzing the redox chemistry of superoxide and, when placed in context with other nickel enzymes, suggest that thiolate ligation is a prerequisite for redox-active nickel sites in metalloenzymes.

Most of the heat capacity of liquid macromolecules arises from vibrational motion. The external contribution is assumed to approach zero at constant volume. The conformational contribution, finally, is calculated using a fit of experimental heat capacities, as available from the ATHAS data bank, to a one-dimensional Ising-type model with two discrete, degenerate states. A stiffness and a cooperativity parameter permit the representation of the experimental data for polyethylene, polypropylene, poly(methyl methacrylate), poly(n-butyl methacrylate), and polystyrene.

This relative Cl-2(+) number density was compared to the total absolute positive ion density (n(i)(+) = n(Cl)(+) + n(Cl2+)) obtained with a Langmuir probe. Both n(Cl2+) and n(i)(+) doubled with increasing rf power from 8 to similar to 55 W in the capacitively coupled (dim) mode. Above the transition from a capacitively to inductively coupled (bright-mode) plasma at similar to 85+/-35 W, n(Cl2+) decayed with rf power while n(i)(+) continued to increase. Consequently, Cl-2(+) is the dominant ion in dim-mode operation and Cl+ is the dominant ion in bright-mode operation, at n(i)(+) greater than or equal to 6 x 10(10) cm(-3). With the plasma operating in the reaction ion etch (RIE) mode (the stage powered at 14.56 MHz, and no TCP power) n(Cl2+) tracked n(i)(+) over the entire range of powers (2-150 W). Thus, Cl-2(+) is the dominant ion during capacitively coupled RIE operation. (C) 1999 American Institute of Physics. [S0003-6951(99)03612-8].

The presence of chemical disorder in the form of like-atom bonding has been unambiguously demonstrated in stoichiometric InP amorphized by ion implantation. In-In bonding comprised 14% +/- 4% of the In-atom constituent bonds.

The delay lines exhibited bias- and temperature-dependent nonlinearity and dispersion, with associated pulse-shaping effects. At low temperatures and under certain bias conditions, the interplay of dispersion and nonlinearity has led to stable and compact wave forms, reminiscent of microwave solitons.

Binding and activation of eta(2)-H-2 trans to CO is nearly invariant to changes in charge and cis ligands SO INORGANIC CHEMISTRY LA English DT Article ID MOLECULAR-HYDROGEN COMPLEXES; INELASTIC-NEUTRON-SCATTERING; METAL DIHYDROGEN COMPLEXES; H-H BOND; R = PH; X-RAY; AGOSTIC INTERACTIONS; 16-ELECTRON COMPLEX; REACTION COORDINATE; CARBONYL-COMPLEXES AB Electrophilic 16e [Mn(CO)(R2PC2H4PR2)(2)](+) complexes (R = Et, Ph) are synthesized by metathesis of MnBr(CO)(R2PC2H4PR2)(2) with Na or Li salts of low-coordinating baron or gallium anions (e.g., [B{C6H3(3,5-CF3)(2)}(4)](-) or [Ga(C6F5)(4)](-)). They contain weak polyagostic interactions that are reversibly displaced by H-2, N-2, and SO2 (which is a surprisingly weak ligand here). The agostic aid H-2 complexes, as well as the gallium anions including the new species [{Ga(C6F5)(3)}(2)(mu-Cl)](-), have been characterized by NMR, IR, and X-ray crystallography. The agostic Mn-H distances (e.g., 2.9 Angstrom) are much longer than those found for the single agostic interactions in Mo(CO)(diphosphine)(2) and [Mn(CO)(3)(PCy3)(2)](+). The H-H and also the Mn-H distances have been determined in the H-2 complex by T-1 measurements for both the H-2 and HD isotopomers. IR data and C-O and M-C bond lengths are used to gauge the pi-acceptor strengths of ligands trans to the CO. The agostic C-H bonds are the weakest ligands and also the weakest accepters, but the H-2 ligand is an excellent acceptor as strong as N-2 and ethylene. The variation of nu(CO) on increasing the basicity of the cis-phosphine (dppe versus depe) in trans-M(CO)(diphosphine)(2)(L) is less than expected and far less than that on increasing the charge on the complex (M = Mn+ versus Mo). The H-H bond lengths (0.87-0.90 Angstrom) and J(HD) NMR couplings (32-34 Hz) in [Mn(CO)(R2PC2H4PR2)(2)(H-2)](+) and other cationic H-2 complexes with trans-CO are strikingly similar to their neutral analogues and nearly invariant. Activation of H-H in the more electrophilic cationic systems occurs primarily via increased a donation from H-2 as compared to the more electron-rich neutral analogues where back-bonding dominates. The nature of the ligand trans to H-2 (the strong acceptor CO here) controls the H-H distance more so than all of the cis ligands combined, especially fbr cationic complexes.

The gels contained ethylene glycol and triethylamine as the template and were heated in quartz glass capillaries at temperatures up to 200 degrees C. The following crystalline products were formed: MnAPO-5, [AFI], CoAPO-5, [AFI], and AlPO4-5, [AFI]. Three nonaqueous systems were investigated in situ, where the crystallization of MAPO-5-type materials were followed. Solvothermal crystallization of MnAPO-5 and CoAPO-5 was studied, and the effect of adding HF as a mineralizing agent was investigated. Time-resolved powder diffraction data were collected using a translating imaging plate (TIP) camera, and crystallization curves were extracted using integrated diffraction peaks. Kinetic analysis of the crystallization curves was performed using an Avrami-type expression, alpha(t) = exp(-(kt)(n)). Apparent activation energies were determined from Arrhenius plots: MnAPO-5, 94 kJ/mol; MnAPO-5(HF), 68 kJ/mol; CoAPO-5, 61 kJ/mol. Crystallization of CoAPO-5 is faster than for MnAPO-5, and the values for n obtained by fitting with the Avrami-type expression were significantly lower for CoAPO-5 than for MnAPO-5.

Vapor deposited water films on a crystalline ice substrate exhibit amorphous growth at temperatures below similar to 110 K. The rate of crystallization for these amorphous films is dramatically accelerated compared to the rate of crystallization observed for the amorphous films deposited directly on Pt(111). We find that the crystalline ice substrate acts as a two-dimensional nucleus for the growth of the crystalline phase, thereby accelerating the crystallization kinetics.

A new perspective of dielectric continuum theory [X. Song and D. Chandler, J. Chem. Phys. 108, 2594 (1998)] aided in characterizing the system-bath interactions of eosin in water. Application of this theory provides solvation energies, which were used within the spectral density representation rho(omega), to calculate the experimental peak shift. Simulations with only solvation contributions to rho(omega), where a substantial amplitude of the solvation occurs within similar to 30 fs, are remarkably consistent with our data. Furthermore, simulations using this theoretical solvation spectral density and an experimentally determined intramolecular spectral density yield an excellent total simulation of the peak shift data over the entire dynamic range. Our experimental results substantiate predictions that interaction-induced polarizability effects, contributing via a similar to 180 cm(-1) band in the spectral density, influence the initial dynamics.

Unfortunately natural systems are more likely to be heterogeneous both in surface shape and surface chemistry. In this paper we discuss the consequences of chemical heterogeneity on wetting. Specifically, a two-dimensional (2D) implementation of a nonlocal density-functional theory is solved for a striped surface model. Both the strength and range of the heterogeneity are varied. Contact angles are calculated, and phase transitions (both the wetting transition and a local layering transition) are located. The wetting properties of the surface are shown to be strongly dependent on the nature of the surface heterogeneity. In addition highly ordered nanoscopic phases are found, and the operational limits for formation of ordered or crystalline phases of nanoscopic extent are discussed.

We have modified the Stillinger-Weber (SW) potential of Feil et al. by adding two new terms: (1) an embedding term that corrects for the variation in Si-Cl bond strength as a function of the number of neighbors, and (2) a four-body term to describe the variation of the Si-Si bond strength as a function of the number of neighbors of each Si atom and the atom types (a bond order correction). Calculated Si etch rates obtained from molecular dynamics simulations using the new potential are in better agreement with recent experimental results than those obtained with the unmodified potential. Predictions of the stoichiometry of the etch products are also markedly different between the two potentials. (C) 1999 American Institute of Physics. [S0021-9606(99)00803-X].

These include baryon number violation, flavor-changing neutral currents, the mu-term, and masses for singlet or vector-like fields under the Standard Model gauge group. For this purpose we introduce an extra non-anomalous U(1)(mu) gauge group. Dynamical supersymmetry breaking in a secluded sector triggers the breaking of the U(1)(mu) and generates soft masses for the superpartners via gauge mediation, with the scalars possibly receiving sizable contributions from the U(1)(mu) D-term. We find several classes of complete and calculable models, in which the messengers do not present cosmological problems and neutrino masses can also be accommodated. We derive the sparticle spectrum in these models and study the phenomenological consequences. We give an exhaustive list of the potential experimental signatures and discuss their observability in the upcoming Tevatron runs. One class of models exhibits interesting new discovery channels, namely WW (E) over bar(T), W gamma (E) over bar(T) and WZ (E) over bar(T), which arise when the next-to-lightest supersymmetric particle is a short-lived SU(2)(w) neutralino.

We show that a sector of the theory, which corresponds to placing an odd number of D3-branes at orientifold fixed points, can give rise to an SU(5) gauge theory with three generations of chiral matter fields. The resulting model is not fully realistic, but the relative ease with which an adequate gauge group and matter content can be obtained is promising. The model is also of interest from the point of view of supersymmetry breaking. We show that, for fixed values of the closed string modes, the model breaks supersymmetry due to a conflict between a nonperturbatively generated superpotential and an anomalous U(1) D-term potential.

The general formalism can be used as a basis for systematic approximations to heavy hadron decay amplitudes such as hard perturbative QCD contributions. We illustrate the general formalism using a simple perturbative model of composite hadrons.

The results shown here were obtained from 504 days of data taken between 31 May 1996 and 25 March 1998. The shape of the measured spectrum is compared with the expectation for solar B-8 neutrinos. The comparison takes into account both kinematic and detector related effects in the measurement process. The spectral shape comparison between the observation and the expectation gives a chi(2) Of 25.3 with 15 degrees of freedom, corresponding to a 4.6% confidence level.

measurement of the central inclusive jet cross section at root s = 1.8 TeV. The measurement is based on an integrated luminosity of 92 pb(-1) collected at the Fermilab Tevatron (p)over-bar-p Collider with the D0 detector. The cross section, reported as a function of jet transverse energy (E-T greater than or equal to 60 GeV) in the pseudorapidity interval [eta] less-than-or-equal-to 0.5, is in good agreement with predictions from next-to-leading order quantum chromodynamics.

LETTERS LA English DT Article ID PARTON DISTRIBUTIONS; DETECTOR; PHYSICS AB Using the D0 detector at the 1.8 TeV (p)over-bar-p Fermilab Tevatron collider, we have measured the inclusive dijet mass spectrum in the central pseudorapidity region [eta(jet)] less-than 1.0 for dijet masses greater-than 200 GeV/c(2). We have also measured the ratio of spectra sigma([eta(jet)] less-than 0.5)/sigma(0.5 less-than [eta(jet)] less-than 1.0). The order alpha(s)(3) quantum chromodynamics predictions are in good agreement with the data and we rule out models of quark compositeness with a contact interaction scale less-than 2.4 TeV at the 95% confidence level.

Net baryon distributions were derived from those of net protons. Stopping (rapidity shift with respect to the beam) and mean transverse momentum [p(T)] of net baryons increase with system size. The rapidity density of negative hadrons scales with the number of participant nucleons for nuclear collisions, whereas their [p(T)] is independent of system size. The [p(T)] dependence upon particle mass and system size is consistent with larger transverse flow velocity at midrapidity for Pb + Pb compared to S + S central collisions.

A higher energy metastable state is formed when H is flipped to the backside of the Si-H bond at monohydride sites. The defect is described by a double-well potential energy. The dipole moment of this "H-flip" defect is larger and increases the infrared absorption. This defect accounts for large structural changes observed on light soaking including larger infrared absorption and volume dilation.

The properties of Li0.9Mo6O17 strongly suggest that the NFL behavior has a purely electronic origin.

Its phase can be related to the expectation value of the position operator, while its modulus provides an appropriate definition of a localization length. The expressions are valid for any fractional particle filling. As an illustration we use z(L) to characterize insulator to "superconducting" and Mott transitions in one-dimensional lattice models with infinite on-site Coulomb repulsion at quarter filling.

The reactions proceed without by-products, unlike those of most chemical (stoichiometric) oxidizing agents. In separate chemistry, the rhenium catalyst brings about the transfer of oxygen atoms between a pair of closed-shell molecules. C1 Iowa State Univ Sci & Technol, Ames Lab, Ames, IA 50011 USA.

Determination of the absolute jet energy scale in the DO calorimeters SO NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION A-ACCELERATORS SPECTROMETERS DETECTORS AND ASSOCIATED EQUIPMENT LA English DT Article ID D0 AB The DO detector is used to study p (p) over bar collisions at the 1800 and 630 GeV center-of-mass energies available at the Fermilab Tevatron. To measure jets, the detector uses a sampling calorimeter composed of uranium and liquid argon as the passive and active media, respectively. Understanding the jet energy calibration is not only crucial for precision tests of QCD. but also for the measurement of particle masses and the determination of physics backgrounds associated with new phenomena. This paper describes the energy calibration of jets observed with the DO detector at the two p (p) over bar center-of-mass energies in the transverse energy and pseudorapidity range E-T > 8 GeV and \eta\ < 3.

Uniquely high values of open-loop gain have been demonstrated, together with good low noise performance and high load driving capability. Implementation of this scheme uses only a minimal number of commercial parts, resulting in a very compact and relatively low power circuit. A detailed theoretical analysis of the dynamic response and noise performance of the circuit is given. Several tests and measurements have been performed to validate the theory and the results are presented. (C) 1999 Elsevier Science B.V. All rights reserved.

In this technique, target molecules were confined to droplets whose volumes were comparable with illumination volumes in diffraction-limited fluorescence microscopy and guided to the waist of a cw probe laser with an electrostatic potential. Concentration detection limits for Rhodamine 6G in water were determined to be similar to 1 fM, roughly 3 orders of magnitude lower than corresponding limits determined recently with diffraction-limited microscopy techniques for a chemical separation of similar dyes. In addition to its utility as a vehicle for probing single molecules, instrumentation for producing and focusing stable streams of 1-2-mu m-diameter droplets may have other important analytical applications as well.

The system permits multipoint, single laser-shot measurements of CO2, O-2, N-2, C3H8, and H2O mole fractions with submillimeter spatial resolution. Selection of appropriate system hardware is discussed, as are subsequent data reduction and analysis procedures. Results are reported for data obtained at multiple crank angles and in two different engine flow fields. Measurements are made at 12 locations simultaneously, each location having measurement volume dimensions of 0.5 mm x 0.5 mm x 0.9 mm. The data are analyzed to obtain statistics of species mole fractions: mean, rms, histograms, and both spatial and cross-species covariance functions. The covariance functions are used to quantify the accuracy of the measured rms mole fraction fluctuations, to determine the integral length scales of the mixture inhomogeneities, and to quantify the cycle-to-cycle fluctuations in bulk mixture composition under well-mixed conditions.

The system incorporates high-performance UV interference filters and a narrow-band, dual-held-of-view receiver for rejection of background sunlight. Daytime performance has been demonstrated up to 5 km with 150-m vertical and Ei-min temporal averaging. The nighttime performance is significantly better with measurements routinely extending from 10 to 12 km with 75-m range resolution and a 5-min temporal average. We describe design issues for daytime operation and a novel daytime calibration technique. (C) 1999 Optical Society of America. C1 Sandia Natl Labs, Diagnost Res Div, Livermore, CA 94551 USA.

Here we show that ubiquitous small-scale magnetic flux "tubes," constantly emerging from subsurface layers, may cause the formation of plasma jets and a sporadic excess of temperature near the solar surface. These flux tubes collide and reconnect, creating a sling-shot effect that generates complex three-dimensional shock waves with the curved surface. Self-focusing of these shocks occurs as they propagate upward in the rarefied atmosphere. Depending on the geometry of the shock collision, highly concentrated energy may be converted entirely into either heat or strong jets, or distributed between the two.

Consistency and stability SO INTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN ENGINEERING LA English DT Article DE meshless methods; smooth-particle hydrodynamics; SPH; moving-least-squares; MLS, Lagrangian hydrodynamics ID SPH; COMPUTATIONS AB The Smooth-Particle-Hydrodynamics (SPH) method is derived in a novel manner by means of a Galerkin approximation applied to the Lagrangian equations of continuum mechanics as in the finite-element method. This derivation is modified to replace the SPH interpolant with the Moving-Least-Squares (MLS) interpolant of Lancaster and Saulkaskas, and define a new particle volume which ensures thermodynamic compatibility. A variable-rank modification of the MLS interpolants which retains their desirable summation properties is introduced to remove the singularities that occur when divergent flow reduces the number of neighbours of a particle to less than the minimum required. A surprise benefit of the Galerkin SPH derivation is a theoretical justification of a common ad hoc technique for variable-h SPH. The new MLSPH method is conservative if an anti-symmetric quadrature rule for the stiffness matrix elements can be supplied. In this paper, a simple one-point collocation rule is used to retain similarity with SPH, leading to a non-conservative method. Several examples document how MLSPH renders dramatic improvements due to the linear consistency of its gradients on three canonical difficulties of the SPH method: spurious boundary effects, erroneous rates of strain and rotation and tension instability. Two of these examples are non-linear Lagrangian patch tests with analytic solutions with which MLSPH agrees almost exactly. The examples also show that MLSPH is not absolutely stable if the problems are run to very long times. A linear stability analysis explains both why it is more stable than SPH and not yet absolutely stable: and an argument is made that for realistic dynamic problems MLSPH is stable enough. The notion of coherent particles, for which the numerical stability is identical to the physical stability, is introduced. The new method is easily retrofitted into a generic SPH code and some observations on performance are made. Copyright (C) 1999 John Wiley & Sons, Ltd.

The unconstrained functionals allow a straightforward application of conjugate gradients by removing the explicit orthonormality constraints on the quantum-mechanical wave functions. However, the removal of the constraints can lead to slow convergence, in particular when preconditioning is used. The convergence properties of two previously suggested energy functionals are analyzed, and a new functional is proposed, which unifies some of the advantages of the other functionals. A numerical example derived from a diamond crystal confirms the analysis. (C) 1999 Academic Press. C1 Univ Calif Berkeley, Dept Phys, Berkeley, CA 94720 USA.

The enhancements of the new sequence, designated BPP-SED, a novel combination of BPP-LED (bipolar-gradient-pulse pair longitudinal eddy current delay) and SED (selective echo dephasing) is demonstrated by measuring self-diffusion coefficients of dilute protein samples (0.5 mM) in limited volumes (250 mu l).

DNA-PK contains the heterodimer Ku and a 460-kDa serine/threonine kinase catalytic subunit (p460), Ku binds in vitro to DNA termini or other discontinuities in the DNA helix and is able to enter the DNA molecule by an ATP-independent process. It is clear from in vitro experiments that Ku stimulates the recruitment to DNA of p460 and activates the kinase activity toward DNA-binding protein substrates in the vicinity. Here, we have examined in human nuclear cell extracts the influence of the kinase catalytic activity on Ku binding to DNA, We demonstrate that, although Ku can enter DNA from free ends in the absence of p460 subunit, the kinase activity is required for Ku translocation along the DNA helix when the whole Ku/p460 assembles on DNA termini, When the kinase activity is impaired, DNA-PK including Ku and p460 is blocked at DNA ends and prevents their processing by either DNA polymerization, degradation, or ligation. The control of Ku entry into DNA by DNA-PK catalytic activity potentially represents an important regulation of DNA transactions at DNA termini.

We and others have recently demonstrated that paclitaxel also activates the c-Jun N-terminal kinase/stress-activated protein kinase (JNK/SAPK) signal transduction pathway in various human cell types, however, no clear role has been established for JNK/SAPK in paclitaxel-induced apoptosis. To further examine the role of JNK/SAPK signaling cascades in apoptosis resulting from microtubular dysfunction induced by paclitaxel, we have coexpressed dominant negative (dn) mutants of signaling proteins of the JNK/SAPK pathway (Ras, ASK1, Rac, JNKK, and JNK) in human ovarian cancer cells with a selectable marker to analyze the apoptotic characteristics of cells expressing dn vectors following exposure to paclitaxel, Expression of these dn signaling proteins had no effect on Bcl-2 phosphorylation, yet inhibited apoptotic changes induced by paclitaxel up to 16 h after treatment. Coexpression of these dn signaling proteins had no protective effect after 48 h of paclitaxel treatment. Our data indicate that: (i) activated JNK/SAPK acts upstream of membrane changes and caspase-3 activation in paclitaxel-initiated apoptotic pathways, independently of cell cycle stage, (ii) activated JNK/SAPK is not responsible for paclitaxel-induced phosphorylation of Bcl-2, and (iii) apoptosis resulting from microtubule damage may comprise multiple mechanisms, including a JNK/SAPK-dependent early phase and a JNK/SAPK-independent late phase.

The calculation of proton affinities and acidities on a surface SO SURFACE SCIENCE LA English DT Article DE charged unit cell; hematite; proton acidities; proton affinities; slab geometry ID DENSITY-FUNCTIONAL THEORY; ENERGY; INTERFACE; OXIDE AB Calculation of the energy of a charged defect on a surface in supercell geometry is discussed. An important example of such a calculation is evaluation of surface proton affinities and acidities, as adding or removing a proton creates a charged unit cell. Systems with periodic boundary conditions in three spatial directions and a vacuum gap between slabs are demonstrated to be inadequate for unit cells having non-zero ionic charge and uniform neutralizing background. In such a system the calculated energy diverges linearly with the thickness of the vacuum gap. A system periodic in two directions and finite in the direction perpendicular to the surface (2-D PBC) with the neutralizing background distributed as the surface charge density is free from this problem. Furthermore, the correction for the interaction of the charged defect with its own translational images is needed to speed up the convergence to the infinite dilution limit. The expression for the asymptotic correction for the energy of interaction of a charged defect with its translational images in 2-D PBC geometry has been developed in this study. The asymptotic correction is evaluated as the interaction energy of a 2-D translationally periodic array of point charges located above and below the plate of non-uniform dielectric. This is a generalization of the method of M. Leslie and M.J. Gillan [J. Phys. C, 18 (1985) 973] for the calculation of the energy of a charged defect in bulk crystals. The usefulness of this correction was demonstrated on two test cases involving the calculation of proton affinity and acidity at the (012) surface of hematite. The proposed method is likely to be important in ab initio calculations of the energy effect of the surface protonation reactions, where computational limitations dictate a small size for the unit cell.

Optimal proton distribution and simulation of surface charge versus pH relationships SO SURFACE SCIENCE LA English DT Article DE hematite; molecular modeling; pH relationships; proton distribution; surface charge ID SOLID-SOLUTION INTERFACE; STATICS CALCULATIONS; (HYDR)OXIDES; CONSTANTS; ACIDITY; BINDING AB A parameterized classical potential model for the interaction of water and hydroxide with iron oxide was used to calculate the optimal proton arrangement and proton binding energies on the (012) surface of hematite. Energy minimization calculations with the parameterized potential model indicate that approximately 75% of adsorbed water molecules are dissociated on this surface, in agreement with recent TPD and HREELS measurements. Surface protonation/deprotonation energies were calculated from the predicted optimal arrangement of protons on the neutral (012) surface. A supercell geometry with translational symmetry in two dimensions and finite in the third dimension (2-D PBC) was assumed. The calculated surface protonation energies were then used to model the experimentally observed surface-charging curve of hematite in aqueous solution. Excellent agreement was found between the calculated and measured surface charge for ionic strengths ranging from 0.001 to 0.1 M. Our calculations favor the value of 8.5 for the pH of zero charge of hematite over the more recent result of 6.7. (C) 1999 Elsevier Science B.V. All rights reserved.

The measurement is interpreted in terms of an error function electron density profile to yield an interfacial width of 0.33 +/- 0.025 nm, Within the context of capillary wave theory, it is shown that this microscopic parameter is in agreement with macroscopic measurements of the interfacial tension. These measurements are compared to computer simulations of water-alkane interfaces. C1 Univ Illinois, Dept Phys, Chicago, IL 60607 USA.

Metallic cesium reacts vigorously with SO2 at temperatures between 100 and 300 K. At 100 K, the amount of SO: that fully dissociates (SO2,gas - S-a + 2O(a)) on the alkali metal is relatively small, and SOx (x = 2-4) species predominate on the: surface. SO3 and SO4 may be formed as a result of the reaction of SO2 with atomic oxygen (SO2 + nO(a) - SO2+n,a where n = 1-2), or by disproportionation of chemisorbed SO2. At 300 K the stability of the CsSOx species is lower than at 100 K, and the formation of CsOy and CsSy becomes important. In the Cs/ZnO and Cs/MoO2 systems, the alkali <-> oxide interactions are very strong. Despite this, the supported Cs atoms retain a large chemical affinity for SO2 and are able to enhance the rate of adsorption of the molecule on the oxide surfaces, even at low coverages (0.1-0.2 ML) of cesium when the alkali atoms are in a highly ionic state: (Csdelta+). The larger the coverage of Cs on ZnO and MoO2, the faster the rate of adsorption of SOL, and the larger the amount of S and SOx (x = 2-4) species present on the surface. The adsorption of SO2 on ZnO and Cs/ZnO surfaces was examined using ab initio self-consistent-field (SCF) calculations and cluster models. The Cs adatoms provide occupied states that are very efficient for bonding interactions with the LUMO of SO2. Cs atoms supported on Zn-terminated terraces of ZnO respond much more strongly to the presence of SO2 than Cs atoms supported on O-terminated terraces. The bonding interactions between the ZnO(0001)-Zn face and SO2 are weak, and promotion with Cs adatoms considerably improves the energetics for SO2 adsorption.

When coherence is lost at the transition temperature T-c, pairing remains, together with phase correlations which are finite in space and time. In conventional metals, Cooper pairs with short-range phase coherence survive no more than 1 K above T-c. In underdoped high-T-c copper oxides, spectroscopic evidence for some form of pairing is found up to a temperature T*, which is roughly 100 K above T-c (refs 1-3). How this pairing and Cooper-pair formation are related is a central problem in high-T-c superconductivity. The nature of this relationship hinges on the extent to which phase correlations accompany pairing in the normal state(4). Here we report measurements of high-frequency conductivity that track the phase-correlation time tau in the normal state of the Bi2Sr2CaCu2O8+delta,s family of underdoped copper oxide superconductors. Just above T-c,we find that tau reflects the motion of thermally generated topological defects in the phase, or vortices(5,6). However, vortex proliferation reduces tau to a value indistinguishable from the lifetime of normal-state electrons at 100 K, well below T*. C1 Univ Calif Berkeley, Dept Phys, Berkeley, CA 94720 USA.

Silica containing ordered mesopores (of nanometre-scale width) can be prepared by templating of surfactant(3,4) and block copolymer(5) liquid-crystalline mesophases, and interfacial phenomena have been used to control the macroscopic form of these materials, providing mesoporous particles(1,6), fibres(7,8) and films(9,10) A variety of spherical or nearly spherical particles has been reported(1,6,7,11-13), but the degree of ordering and the range of the porous mesostructures have been limited. Here we report a rapid, aerosol-based(14-16) process for synthesizing solid, well-ordered spherical particles with stable pore mesostructures of hexagonal and cubic topology, as well as layered (vesicular) structures. Our method relies on evaporation-induced interfacial self-assembly(17) confined to spherical aerosol droplets. This simple, generalizable process can be modified for the formation of ordered meso-structured thin films. C1 Univ New Mexico, NSF, Ctr Microengineered Mat, Adv Mat Lab, Albuquerque, NM 87106 USA.

This is done in the framework of a classical solution of a Particles-plus-Roto Model. The competition is governed by the relative strength of the residual interaction between the blades in the shears and the rotational energy of the core. The results are summarized in terms of a "phase-diagram'' of these two modes of rotation that is applicable for all mass regions. We find that in order for the shears mechanism to dominate, the deformation of the core has to be epsilon less than or similar to 0.12. (C) 1999 Published by Elsevier Science B.V.

The resulting objects have a number of qualitative features in common with string theory D-branes; they support a gauge field and flux strings can end on them. In this letter, we explore this analogy further, by considering what happens when N of these "branes" approach each other. Unlike in the case of D-branes, we find a reduction of the gauge symmetry as the "branes" overlap. This can be attributed to a tachyonic instability of the flux string stretching between the branes.

Both models support a temperature profile that varies over the star's volume and the consequences of this are model independent. However, in our model the analogue of the bag pressure is (T, mu)-dependent, which is not the case in the bag model. This is a significant qualitative difference and comparing the results effects a primary goal of elucidating the sensitivity of quark star properties to the form of the EOS.

at root s=183GeV SO PHYSICS LETTERS B LA English DT Article ID ELECTRON-POSITRON COLLISIONS; STATE QED CORRECTIONS; W-PAIR PRODUCTION; MONTE-CARLO; 4-FERMION PRODUCTION; E+E COLLISIONS; L3 EXPERIMENT; DETECTOR; ENERGIES; LEP2/NLC AB A study of neutral-current four-fermion processes is performed using a data sample corresponding to 55.3 pb(-1) of integrated luminosity collected by the L3 detector at LEP at an average centre-of-mass energy of 183 GeV. The neutral-current four-fermion cross sections for final slates with a pair of charged leptons plus jets and with four charged leptons are measured to be consistent with the Standard Model predictions. Events with fermion pair masses close to the Z boson mass are selected in all observable final states and the ZZ production cross section is measured to be sigma ZZ = 0.30(-0.16-0.03)(+0.22 + 0.07) pb, in agreement with the Standard Model expectation. No evidence for the existence of anomalous triple gauge boson ZZZ and ZZ gamma couplings is found and limits on these couplings are set. (C) 1999 Elsevier Science B.V. All rights reserved.

The photoactive noncovalent complexes are assembled via salt-bridge formation between carboxyl-containing porphyrin photodonors and a monoprotonated pentapyrrolic sapphyrin acceptor. These complexes are formed with a K-a of ca. 10(3) M-1 upon mixing the receptor and substrate in their respective free-acid and free-base forms in CD2Cl2 (as judged by H-1 NMR spectroscopic means). Upon irradiation at 417 nm, singlet-singlet energy transfer from the porphyrin to the sapphyrin subunit takes place readily with energy transfer dynamics that are consistent with a Forster-type mechanism. The title systems thus appear to be prototypic of a new kind of noncovalent energy transfer modeling that is predicated on the use of anion chelation.

After displacement of most of the liquid crystal by compression, a 10.2 Angstrom thick layer of 8CB was found between mica surfaces in the range of applied pressures from 1 to 20 MPa. Under these conditions, we found that friction depends linearly on contact area in the 1-1.5 MPa range. We found that the critical shear stress was anisotropic, with values of 0.28 MPa for shear along the 8CB molecular axis and 0.42 MPa for shear in the perpendicular direction. This anisotropy was observed through all the ranges of load where slip occurred. At higher loads (1.5-2.7 MPa), the critical shear stresses increase to 0.6 and 1.2 MPa for parallel and perpendicular shear, respectively.

In this paper, we extend our characterization of the parameters that determine the utility of the approach, and we generalize the approach in a way that supports detection of common classes of functionally coupled genes (e.g., transport and signal transduction clusters), Now that the analysis includes over 30 complete or nearly complete genomes, it has become clear that this approach will play a significant role in supporting efforts to assign functionality to the remaining uncharacterized genes in sequenced genomes.

The multiplexed eight-array system is based on capillary microfluidics and capillary array electrophoresis. Three short-tandem-repeat loci, vWA, THO1, and TPOX, are coamplified simultaneously in a fused-silica capillary by a hot-air thermocycler. Blood is directly used as the sample for polymerase chain reaction (PCR) without any pretreatment. Modifications of standard protocols are necessary for direct PCR from blood. A programmable syringe pump plus a set of multiplexed liquid nitrogen freeze/thaw switching valves are employed for liquid handling in the fluid distribution network. The system fully integrates sample loading, PCR, addition of an absolute standard, on-line injection of sample and standards, separation and detection. The genotypes from blood samples can be clearly identified in eight parallel channels when the electropherograms are compared with that of the standard allelic ladder by itself. Regeneration and cleaning of the entire system prior to subsequent runs are also integrated into the instrument. The instrumentation is compatible with future expansion to hundreds of capillaries to achieve even higher throughput. C1 USDOE, Ames Lab, Ames, IA 50011 USA.

Two PL bands are observed: (1) a band-to-band emission with a maximum at 1.09 eV, and (2) a deep "defect'' luminescence at about 0.8 eV. PL mapping of 10 cm x 10 cm wafers revealed inhomogeneity of the band-to-band PL intensity which could be correlated to the distribution of minority carrier diffusion length in the wafer bulk. We have also observed that the intensity of the 0.8 eV band is strongest along those grain boundaries where the band-to-band PL is suppressed as well as minority carrier diffusion length. The origin of the 0.8 eV luminescence band is discussed. (C) 1999 American Institute of Physics. [S0003-6951(99)00611-7]. C1 Univ S Florida, Ctr Microelect Res, Tampa, FL 33620 USA.

Remediation treatments included Cr-free groundwater and buffered and unbuffered Fe(II) solutions as either FeCl2 and FeSO4. The slow release of Cr(VI) from the Fe-oxide rich subsurface sediment following exposure to Cr-free solutions indicated that simple pump-and-treat procedures would require extended operation time to meet regulatory standards. In situ reduction was confirmed by the loss of Cr(VI) and Fe(II) from solution and a drop in pH compared to control systems. Batch and column-effluent Cr(VI) decreased with increasing Fe(II), generally falling below detection limits as the persistence of Fe(II) occurred. However, Cr-Dissolved, presumably Cr(III), exceeded regulatory limits due to the low pH (approximate to 3.0) induced by oxidation and hydrolysis of Fe(II). Acetate-buffered Fe(II) solutions maintained an elevated pH in the presence of Cr(VI) reduction, making the treatment effective at lowering Cr-Dissolved in batch evaluations. Acetate increased Cr(VI) mobility in columns ahead of the reactive Fe(II) front, suggesting that in situ reduction using soluble chemical additives may be somewhat ineffective due to the enhanced migration of Cr, either Cr(III) or Cr(VI), induced by the treatment solution.

We present a full wave analysis for ion cyclotron waves propagating from the equatorial magnetosphere to the ground. Our analysis demonstrates that strong mode coupling occurs near the He+ and O+ resonance locations which allows the equatorial waves to penetrate to ionospheric altitudes with substantial amplitude and shifted polarization consistent with observational studies.

The simulations are done using the recently recalculated runaway avalanche rates. The temporal evolution of these simulations is in good agreement with ground-based photometer and CCD TV camera observations of red sprites. Our model naturally explains the "hairline" of red sprites as a boundary between the region where the intensity of optical emissions associated with runaway breakdown has a maximum and the region where the intensity of optical emissions caused by conventional breakdown and ambient electron heating has a maximum. Other important characteristics of the simulated sprite such as color, shape, altitude, and intensity are in agreement with the observations as well. We also present for the first time simulations of red sprites with a daytime conductivity profile. C1 Univ Calif Los Alamos Natl Lab, Atmospher & Climate Sci Grp, Los Alamos, NM 87545 USA.

Potassium mellitate (1) crystallizes in the orthorhombic space group Pbca, with unit cell dimensions of a = 18.091(4), b = 12.634(3), c = 22.151(4) Angstrom, beta = 90 degrees, V = 5062.9(19) Angstrom(3) and Z = 8. In contrast, cesium mellitate (2) crystallizes in the monoclinic space group P2(1)/c, with unit cell dimensions of a = 13.836(3), b = 20.818(4), c = 9.539(2) Angstrom, beta = 103.52(3)degrees V = 2671.5(10) Angstrom(3) and Z = 4. Both structures are comprised of a 3D network of mellitate ion stacks, metal ions and water molecules which are linked by hydrogen bonds. In the case of potassium mellitate (1), two K+ ions (K(1) and K(4)) are located between the mellitate ions in the stacks. The remaining K+ ions occupy positions between the mellitate stacks. In cesium mellitate (2), the Cs+ ions are all located between the mellitate stacks. Two new coordination modes of the carboxylate groups are reported. Potassium mellitate (1) exhibits a tridentate binding mode in which two potassium ions are coordinated to three carboxylates on one mellitate ion. Cesium mellitate displays a similar mode but with an additional cesium ion coordinated to two of the three carboxylate groups. These new modes are attributed to the larger number of cations in these compounds as compared with mellitate compounds containing +2 and +3 cations. (C) 1999 Elsevier Science S.A.

Experimental observations indicate a well-aligned grain structure and quasiperiodic nonaligned "extended defect'' layers transverse to press direction. The local remanence of the "defect'' layers is far from saturation when the external field is removed. The layers are enriched with inclusions of approximate composition Nd7Fe3, generally with a polygonal shape, and are associated with the original ribbon interfaces. They may be responsible for a high coercivity mechanism, since the motion of reverse domains can be impeded by these layers, even when they are nucleated. Thus, a delayed nucleation of reversed domains seems to be a limiting factor for magnetization reversal and coercivity force. Both Lorentz magnetic imaging and high-resolution microscopy highlight the role of magnetocrystalline anisotropy for domain wall-grain boundary interactions and pinning. Local remanence was estimated directly from magnetic moment sensitive Foucault images. (C) 1999 American Institute of Physics. C1 Brookhaven Natl Lab, Dept Appl Sci, Upton, NY 11973 USA.

Relatively simple forms to describe limiting cases exist, but the general intermediate case requires a more complex analysis. Maugis, using a Dugdale model [D. Maugis, J. Colloid Interf. Sci 150, 243 (1992)], provides an analytic solution, but the resulting equations are cumbersome if one wishes to compare with experimental data such as atomic force microscope measurements. In this paper we present a simpler general equation that approximates Maugis' solution extremely closely. The general equation is amenable to conventional curve fitting software routines and provides a rapid method of determining the value of the "transition parameter" which describes the range of surface forces.

There was on average a 99.9% reduction of CD8 cells in peripheral blood in six infected Macaca mulatta treated with OKT8F. The apparent CD8 depletion started 1 h after antibody administration, and low CD8 levels were maintained until day 8. An increase in plasma viremia of one to three orders of magnitude was observed in five of the six macaques. The injection of a control antibody to an infected macaque did not induce a sustained viral load increase, nor did it significantly reduce the number of CD8(+) T cells. These results demonstrate that CD8 cells play a crucial role in suppressing SIV replication in vivo. C1 Rockefeller Univ, Aaron Diamond AIDS Res Ctr, New York, NY 10016 USA.

Motion on this length scale can be expected to be particularly revealing of collective phenomena. However, due to neutron scattering experimental difficulties, namely to all-pervasive spurious multiple scattering effects and to the weakness of the signal at wave numbers corresponding to this length scale, very little is experimentally known so far about the dynamics in this range. We have developed a new experimental strategy to overcome these difficulties, and applied this novel approach to the study of the archetypal fragile glass former CKN. Our results provide the first direct experimental evidence for the existence of a first, fast structural relaxation step in the supercooled liquid phase, which does not scale with the viscosity and which cannot be attributed to extra vibrational modes, either propagating or local. The enhanced slowing down with decreasing temperature of the slow (alpha) relaxation process in the wave number domain of the intermediate range order also allowed us to investigate the temperature dependence of the amplitude of this relaxation step in a model independent manner. In contrast to some previous findings, our direct results show no sign of any critical singularity above the glass transition temperature. C1 Los Alamos Natl Lab, Los Alamos, NM 87545 USA.

Rietveld refinement of the powder X-ray diffraction (XRD) data confirmed the presence of layers of corner-shared VO6 octahedra with V-O bond distances of 1.928(1) Angstrom (x 4) and 2.04(2) Angstrom (X 2) perpendicular to the tetragonal c axis. X-ray absorption near-edge spectroscopy (XANES) indicated that the Eu is mixed-valent [Eu(II)/Eu(III)], while vanadium exists exclusively in the trivalent state. These valence assignments were supported by the results of temperature-dependent magnetic susceptibility and Mossbauer spectroscopy data. Variable temperature electrical resistivity measurements indicated that the sample was insulating (rho(RT) approximate to 10(4) Ohm-cm). The compound undergoes a charge-ordering transition associated with the Eu sublattice at 445 K, as evidenced by Mossbauer spectroscopy, electrical resistivity, and in situ high temperature X-ray diffraction studies.

The mechanism of oxidation protection is the formation of a borosilicate glass scale that flows to form a passivating layer over the base intermetallic. The compositional homogeneity range for T1 (Mo5Si3Bx) phase was determined to be much smaller than that reported previously by Nowotny. Compressive creep measurements show that materials based on the phase assemblage of T1-T2 (Mo5SiB2)-Mo3Si have high creep strengths similar to single phase Mo,Si,. Electrical resistivity of selected compositions was also measured and varied from approximate to 0.06 m Omega-cm at room temperature to 0.14 m Omega-cm at 1500 degrees C. Temperature coefficient of resistivity (TCR) was estimated to be on the order of 1 x 10(-4) C-1 for most compositions. (C) 1999 Elsevier Science S.A. All rights reserved.

High purity single crystals of Mo5Si3 have been synthesized by both optical floating zone and Czochralski methods. The thermal and elastic properties of the Mo5Si3 single crystals were experimentally measured. Results show that Mo5Si3 has significant thermal expansion anisotropy along the a and c directions with alpha(c)/alpha(a) = 2.2. The single crystal elastic moduli of Mo5Si3 indicate that it has less elastic anisotropy and lower shear moduli than transition metal disilicides. Tensile stresses of up to 1.8 GPa can develop at grain boundaries after cooling from the melting point due to the thermal expansion mismatch in Mo5Si3, causing grain boundary cracking during processing of polycrystals. Room temperature Vickers indentation tests on (100) and (001) planes have been performed with different indenter diagonal orientations and the orientation dependence of hardness and fracture toughness of Mo5Si3 single crystals have been obtained. The corresponding deformation and fracture modes have been revealed by microscopy studies. Finally, a comparison of Mo5Si3.with other high temperature structural silicides is discussed.

This material can be alloyed with other ceramics, e.g. Si3N4. to increase the cracking strength, toughness, and oxidation resistance. Matrix toughness is shown to have a significant influence on increasing the matrix cracking stress and is one of the few material variables that can be controlled. The uniaxial stress-strain behavior of MoSi2-Si3N4 matrix composites reinforced with SCS-6 fibers demonstrates a high load carrying capacity at high strains. The overall toughness can also be significantly enhanced, particularly at high temperatures. These results suggest that the alloying capabilities of MoSi2 matrix systems will provide the flexibility needed to achieve further improvements in material performance for silicon-base composites.

For alpha-Mo volume fractions of approximate to 50% sound castings were obtained. For lower a-Mo volume fractions such as 25% macroscopic cracks were often observed. Preliminary oxidation tests verified the expected increase in the oxidation resistance as the B-concentration increases and the a-Mo volume fraction decreases. Also, the formation of glass films was observed. Depending on composition and heat treatment, the room temperature flexure strengths varied usually between 300 and 600 MPa. To some extent, these variations could be rationalized by differences in the microstructures. Annealing for 1 day at 1873 K in vacuum caused distinct microstruclural coarsening. Annealing was sometimes accompanied by microcracking in the Mo3Si and the T2 phases. Cooling curves suggest that the liquidus temperature of the T2 phase is above 2400 K. Depending on the composition, Anal freezing of Mo-Si-B alloys was found to occur at temperatures as low as 2200 K. Care is therefore required during thermomechanical processing to avoid the formation of liquid phases. (C) 1999 Elsevier Science S.A. All rights reserved.

Re is found to be a potent solution hardening addition to MoSi2 over the entire temperature range, much more than would be expected from their atomic size mismatch or modulus mismatch. In addition ReSi2-x has about twice the hardness of pure MoSi2 at all temperatures. This may be related to the structure of ReSi2-x which nominally has the same tetragonal C11(b) structure as MoSi2 but is Si-deficient (x = 0.25, i.e. the composition is Re4Si7). The Si deficiency is accompanied by some unusual incommensurate periodicities in the structure which themselves give rise to orthorhombic and monoclinic distortions. The resulting microstructure probably explains the high strength of Re4Si7 and the potent hardening effect of Re in MoSi2 may be due to the accompanying Si vacancies. (C) 1999 Elsevier Science S.A.

The purpose of adding carbon was to form silicon carbide particles (SICp) in situ and reduce the inherent presence of SiO2 in MoSi2. The carbon additions were made via polymeric coatings on MoSi2 particles by two processes, Phenolic Resin Based Carbon by Solvent Evaporation (PRBCSE) and Aqueous Dispersion Flocculation (ADF). The sintering temperatures and times ranged from 1600 to 1800 degrees C, and from 1 to 100 h, respectively. The addition of carbon did reduce the presence of SiO2 and there was formation of SiCp. However, the SiCp formation was less than expected, a maximum of 1.4 vol.% SiCp was formed. The Nowotny phase (Moless than or equal to 4.8Si3Cless than or equal to 0.6) was observed in the sintered samples. The in situ formation of SiCp would increase the toughness of MoSi2 by serving as a reinforcement. The reduction in the amount of SiO2 would reduce the incidence of grain boundary sliding caused by viscous flow of SiO2 at elevated temperatures. (C) 1999 Elsevier Science S.A. All rights reserved.

The MoSi2 matrix microstructure was typical of a splat quenched plasma spray processed material with porosity < 5%. Matrix cracking occurred between fibres and was attributed primarily to differences in the coefficient of thermal expansion of MoSi2, SiC and the steel substrate. Evidence for the formation of SiC by interfacial reaction between the fibre C coating and the MoSi2 matrix has been observed, although this reaction was not uniform at all points on the interface. SIC formation has been suggested to affect the bonding between the fibre and the matrix and the subsequent mechanical properties of consolidated material. Pest oxidation bf the MoSi2 matrix has been used to extract the SiC fibres after plasma spraying to assess the effect of process induced damage on the fiber properties in the matrix. However, the extraction process itself caused some changes to fibre properties which made analysis problematical. The similar to 3.1 GPa as-supplied mean tensile fibre strength was retained during plasma spraying, but the Weibull modulus reduced from 25 to 11, i.e. the spread of fibre strengths increased. Mean bend strain and Weibull modulus were reduced from 1.78 to 1.57 and from 25 to 10 respectively. The fibre surface integrity was affected by both oxidation effects during extraction and by the impact of MoSi2 droplets during spraying. (C) 1999 Elsevier Science S.A. All rights reserved.

Alumina particles entrained in a stream of nitrogen gas impacted the target material at a velocity of 40 m s(-1). Impingement angles of either 60, 75 or 90 degrees were used. It was found that the erosion rate for the Si3N4-MoSi2 composite (measured at room temperature) was a maximum at the 90 degrees incident angle, erosion behavior typical of brittle materials. The erosion rate of the composite at a 75 degrees impingement angle increased slightly with increasing test temperature up to 700 degrees C (i.e. from 4.1 to 4.9 mm(3) g(-1)). At 900 degrees C, the measured erosion rate decreased to 2.9 mm(3) g(-1). The erosion behavior of the Si3N4-MoSi2 composite was compared to that of commercially available Si3N4.

Additionally, the eutectic interfaces are modeled as boundaries between two anisotropic half-spaces. The misorientation between MoSi2-Mo5Si3 is obtained from the literature for Mo5Si3 precipitates in MoSi2 and by electron diffraction in the scanning electron microscope (SEM) for the opposite case. Tensile stresses of up to 3 GPa can develop after cooling from the eutectic temperature due to the thermal expansion mismatch between the phases. Electron microscopy of are-melted Si-rich Mo,Si, shows that stresses are relieved by intergranular fracture in Mo5Si3 and either dislocation plasticity or transgranular cracks in MoSi2, in a manner consistent with the calculations.

The corrosion behavior of MoSi2 is compared to an alumina-zirconia-chrome-silica refractory (AZCS). The corrosion rates were evaluated by measuring dimensional changes at, above, and below the molten glass line. MoSi2-based materials perfomed at least as well as AZCS above and below the glass line, but were somewhat inferior at the glass line. The kinetics and mechanisms of corrosion of MoSi2 varied with position in the melt. Above the glass line a semi-protective SiO2 layer forms. Below the glass line, a protective Mo-rich layer forms. At the glass line, simultaneous dissolution of SiO2 and vaporization of MoO3 leads to comparatively rapid loss of material. Based on microstructural studies, a phenomenological model is proposed that illustrates the basic mechanisms of corrosion in these three regions. (C) 1999 Elsevier Science S.A. All rights reserved.

These TCSM: catalysts were used to catalyze the hydrogenation of arenes (Rh-CNR2/Pd-SiO2 and Rh-CNR3/M-SiO2) and cyclohexanone (Pt-CNR2/Pd-SiO2) under the mild conditions of 40 degrees C and I atm. They exhibit activities that are higher than those of the separate homogeneous rhodium (or platinum) isocyanide complex, the separate silica-supported metal heterogeneous catalyst, or the rhodium (or platinum) complex catalyst tethered on just SiO2. The activities of the TCSM catalysts are strongly affected by the nature and loading of the supported metal in the catalyst. Among the three silica-supported metal M-SiO2 (M = Pd, Pt, Ru) catalysts, the rhodium complex Rh-CNR3 tethered on Pd-SiO2 exhibits the highest activity for the hydrogenation of toluene (TOF = 5.5 mol H-2/(mol Ph min) and TO = 2420 mol H-2/mol Ph during 8.5 h). The Rh-CNR3/Pd-SiO2 catalyst with 10 wt % Pd is more active than its counterparts with higher or lower palladium loadings. IR (DRIFT) spectral studies of the TCSM catalysts before and after being used for toluene hydrogenation show that the isocyanide ligands remain coordinated to the rhodium (or platinum) center even after extended use. Atomic emission spectroscopic analysis of hydrogenation solutions shows that there is no rhodium (or platinum) leaching into the solutions. C1 Iowa State Univ, Dept Chem, Ames, IA 50011 USA.

The carbon reservoir effect purported to exist in Quaternary lacustrine sediments of the McMurdo Dry Valleys was investigated by studying C-14 distribution, and testing alternate dating techniques. Our results show that the carbon reservoir effect is not pervasive, Stream and near-shore microbial mats and dissolved inorganic carbon (DIC) in the surface waters of Lake Fryxell are in equilibrium with modem (CO2)-C-14. The surface waters of Lake Hoare and Lake Bonney, however, have DIC C-14 ages of 1650 and 2080 yr B.P., respectively. These older age estimates are suggested to be due to the direct input of large amounts of glacial melt with relict DIG. On the other hand, Lake Fryxell receives only a minor component of its inflow directly from a glacier, while a large component must travel long distances in numerous shallow ephemeral streams after leaving local valley glaciers. This mode of melt-water input allows the water to equilibrate with modern CO2 before entering the lake. Bottom-water C-14 ages for Lake Hoare closely match surface sediment ages, supporting the widely published period similar to 1200 yr B.P. (after a 1650 yr reservoir correction) when most dry valley lakes apparently evaporated to small brine ponds and/or disappeared completely. Lake Bonney bottom-water is similar to 8000 yr B.P. Carbon dating is shown to be a viable technique for lake edge deposits, and possibly lake bottom deposits where a correction to the sediment surface ase can be obtained. However, we conclude that deep-water paleolake deposits can not be reliably dated using C-14 alone because of an inability to determine the age of the reservoir correction (i.e. accounting for the initial carbon reservoir, plus the age of the bottom water). A suite of alternative and complimentary dating techniques were tested on modern and late Holocene lacustrine deposits. These include thermoluminescence (TL), Pb-210,Cs-137,and paleomagnetism. Of these techniques, TL (or the more sensitive optically stimulated luminescence) holds the most promise for correcting lake sediment C-14 ages. TL dating of the modem Lake Hoare sediments showed an similar to 1000 yr relict signal. This signal is unaffected by the age of the lake water. Both Pb-210 and Cs-137 occurred in very low levels in the sediments and do not appear to be viable dating techniques for the perennially ice-covered lakes of the McMurdo Dry Valleys. Paleomagnetism was not suited to the coarse-grained nature of Lake Hoare bottom sediments, but could be a useful alternative given a finer sediment type. (C) 1999 Elsevier Science B.V.

On the assumption that such trends will continue, estimates are made for some simple cases of the energy demands required to stabilize the world's population in the period 2100-2150. An assessment is made of how these energy demands might be met, capitalizing as much as possible on the indigenous energy resources for each of the ten major regions of the world: North America, Latin America, Europe OECD, Former Soviet Union and Central and Eastern Europe, China, Pacific OECD, East Asia, South Asia, Africa, and the Middle East. Consideration is also given to the potential need to limit carbon emissions because of global-warming concerns. The study highlights the crucial nature of energy-efficiency improvements and the need to use all energy sources if the world is to find a sustainable future with a much improved standard of living in the developing world. While, globally, there are huge resources of fossil fuels, they are unevenly distributed and some of the areas experiencing major population growth are not well endowed with them. Even allowing for the substantial deployment of renewable energies (biomass, geothermal, hydro-,tide, wave and wind power), if fossil-fuel use is restricted or has limited availability, there will be a need in a number of regions (e.g. South Asia) for substantial amounts of nuclear and solar energy to meet their long-term needs. The deployment of more fission power can build upon the existing successes. The availability of fusion power will depend upon the pace of the development program and, in principle, fusion-power deployment might start around the middle of the 21st century. Example scenarios of possible contributions of the various energy sources are described, to illustrate the potential roles for fission and fusion power.

As a result of the worldwide research on tokamaks, the scientific and technical issues for achieving an ignited plasma are better understood and the remaining questions more clearly defined. The principal research topics that have been studied on TFTR are transport, magnetohydrodynamic stability and energetic-particle confinement. The integration of separate solutions to problems in each of these research areas has also been of major interest. Although significant advances-such as the reduction of turbulent transport by means of internal transport barriers, identification of the theoretically predicted bootstrap current, and the study of the confinement of energetic fusion alpha-particles-have been made, interesting and important scientific and technical issues remain for achieving a magnetic fusion energy reactor. In this paper, the implications of the TFTR experiments for overcoming these remaining issues will be discussed. C1 Princeton Univ, Plasma Phys Lab, Princeton, NJ 08543 USA.

The ICF programme, funded by the Defense Program in the USA, has clearly demonstrated there is sufficient confidence in ignition and gain to proceed with construction of the National Ignition Facility, which will test the detailed physics of targets suitable for IFE. In September 1998, the facility was about 40% complete and on schedule and within budget for completion in 2003. X-ray-drive ignition is planned for 2007, followed by direct-drive ignition experiments. The other major elements of an IFE development programme, namely, driver, target factory, and target chamber developments can be investigated separately in affordable programmes. Although much work remains, there are concepts for adequately high driver efficiency and target gain, target cost and target chamber survivability to make an exploratory programme in IFE attractive.

Many scientists believe that both inertial and magnetic fusion can meet the scientific challenge in the sense that they can produce net energy. The National Ignition Facility is expected to demonstrate ignition of an inertially confined plasma within a decade. The economic and environmental challenges will remain. This paper describes research on ion beam inertial fusion. Ion accelerators are, in many ways, ideally suited to the requirements of fusion power production. They can be durable, reliable, and efficient. They can easily achieve the required pulse repetition rates. Cost and beam quality are the principal issues. The cost of a fusion accelerator, if it were built with today's technology, would be acceptable for large power plants (several gigawatt electric). Cost reductions that will allow good economics at smaller plants appear possible. The environmental issue is activation produced by neutrons from deuterium-tritium fuel. For ion beam fusion, it appears possible to shield the structure of the fusion chamber with a neutronically thick liquid layer. This method of protection greatly relaxes the requirements on materials and endows deuterium-tritium fusion systems with many of the advantages of advanced, aneutronic fusion systems. The inertial fusion community in the United States has recently proposed a new programme for the development of inertial fusion as a commercial energy source. This paper gives a brief description of the proposed programme. C1 Univ Calif Berkeley, Lawrence Berkeley Lab, Berkeley, CA 94720 USA.

This computation is carried out for general values of the de Broglie density.

In addition, we show how, given a particular Hamiltonian, to produce many Hamiltonians that have the same time-one map so that one has a large class of Hamiltonians from which to choose the 'best' design. We also show how to produce many symplectic maps that are given explicitly rather than implicitly so that the design problem is more tractable. (C) 1999 Elsevier Science B.V. All rights reserved.

All our calculations used the MOLPRO quantum chemistry package, with Dunning's correlation consistent augmented valence triple zeta 1-electron basis set. The 1 (2)A' and 1 (2)A" energies are calculated at the restricted open shell coupled cluster singles doubles with perturblative triples (RCCSD-T) level, whilst the 2 (2)A'-1 (2)A' energy difference and the non-adiabatic coupling are calculated via the multireference configuration interaction (MRCI) technique. The non-adiabatic coupling is evaluated from transition matrix elements of the angular momentum operator, namely [1 (2)A " \(L) over cap\ 1 (2)A'] and [1 (2)A " \(L) over cap(x)\ 2 (2)A']. The surfaces in a diabatic representation are fitted to rotated-Morse cubic-spline functions. The empirical long-range potentials of Dubernet and Hutson (J. Phys. Chem., 1994, 98, 5844), together with empirical short range potentials, are then combined with the fitted ab initio surfaces to produce a set of global potential energy surfaces. Convergence tests show that the height of the barrier at C-2v geometries is 0.4361 eV for the 1 B-2(1) state, and occurs at a ClHCl bond angle of 137 degrees. The collinear barrier heights are 0.4939 eV on the (2)Sigma(u)(+) surface and 0.9416 eV on the (2)Pi(g) surface. C1 Univ Manchester, Dept Chem, Manchester M13 9PL, Lancs, England.

An all-electron triple-zeta valence plus polarization basis set was used in all calculations. The equilibrium CCSD(T) geometry of FeCO+ is found to be linear ((4)Sigma(-)) with a Fe+ to CO distance of 1.905 Angstrom and a CO bond distance of 1.133 Angstrom. The dissociation energy D-0 of (4)Sigma(-) FeCO+ to D-6 Fe+ and (1)Sigma(+) CO is predicted to be 28.8 kcal mol(-1), which is within the experimental range. Excited state properties including potential energy surfaces and D-e are predicted for the low lying sextet and quartet states of FeCO+. The first excited state is predicted to be 48 with a D-e of 17.6 kcal mol(-1). The lowest sextet state is predicted to be (6)Delta with a D-0 of 12.3 kcal mol(-1). Several examples of pathological behavior at many levels of theory have been discovered and are discussed. C1 Iowa State Univ Sci & Technol, Ames Lab, Dept Chem, US DOE, Ames, IA 50011 USA.
