The model combines a fracture mechanics failure criteria and a microstructurally based description of fracture. Microstructurally related inputs such as pore-size distribution, particle size, bulk density, particle fracture toughness, the number of pores per unit volume, and specimen geometry (size and stressed volume) are utilized in the model. Microstructural inputs to the model code, determined by quantitative image analysis of prepared specimens of the graphites, are reported. The Burchell fracture model was successfully applied to four graphites of widely different texture, ranging from a fine-grain, high-strength aerospace grade (POGO AXF-5Q) to a coarse-grain, low-strength electrode graphite (AGX). The excellent performance and versatility of the Burchell fracture model was attributed to its sound physical basis. The potential for applying the Burchell fracture model to irradiated graphites was explored and the model was shown to qualitatively predict the influence of neutron damage on the strength of a nuclear graphite.

In duplex form, however (with a deoxycytidine opposite the adduct), the adducted 11mer migrated faster than the parent duplex, Absorption and fluorescence studies indicated significant interaction of the aminopyrene residue with the DNA bases in the modified 11mer, The spectroscopic data also suggested the presence of one or more conformers in which the aminopyrene residue is quasi-intercalative, as well as one(s) in which the aminopyrene is externally bound, Thermodynamic parameters for the helix-to-coil transitions for the 11mer duplex were determined, The difference in free energy (Delta Delta G degrees) between the unmodified and modified sequences was relatively small (similar to 1.2 kcal/mol), Circular dichroism spectra indicated the presence of essentially B-form DNA, The energy minimizations suggested that the most stable conformers shared a common feature: displacement of the modified guanine from the double helix, In the global minimum, the aminopyrene residue was inserted in the helix in the site of displaced guanine. In other low energy structures, the aminopyrene was also displaced towards the minor groove (in addition to guanine), or partly inserted and partly in the groove, More conventional structures were also encountered, with anti-guanine within the helix and aminopyrene in the major groove, or syn-guanine within the helix, and aminopyrene in the minor groove, Such structures were 12-20 kcal/mol less stable than the global minimum, however, The C8-guanine adduct of aminopyrene thus appears to perturb the B-DNA structure to a greater extent than do the adducts of less bulky amines such as aminofluorene and 4-aminobiphenyl.

When Mono-S FPLC purified proteins were assayed against defined oligomers containing either epsilon A or epsilon C, it was found that epsilon A and epsilon C glycosylases were completely separated, It could also be demonstrated that each enzyme bound to and cut only epsilon A- or epsilon C-containing oligomers respectively, There was no overlap in specificity for these two substrates. Several other human glycosylase substrates were also tested and none were cleaved by epsilon C glycosylase, The epsilon C glycosylase activity identified in the present study apparently represents a previously unknown glycosylase, This work also suggests that enzyme recognition of closely related DNA adducts may depend upon subtle changes in local conformation.

By using infrared-visible sum frequency generation to study the hydrogenation of ethylene on Pt(111), it was found that the surface concentration of pi-bonded ethylene, the key reaction intermediate, represented approximately 4% of a monolayer. Thus the absolute turnover rate per surface adsorbed ethylene molecule is 25 times faster than the rate measured per platinum atom. To explain these results, we propose a model of weakly adsorbed ethylene intermediates reacting on atop sites. C1 UNIV CALIF BERKELEY,DEPT CHEM,BERKELEY,CA 94720.

The reaction stops when the Pt tip becomes contaminated with carbon, after the removal of similar to 10(7)-10(8) carbon atoms, but can be regenerated by removing material from the tip by application of a voltage pulse. Dissociative adsorption of H-2 and O-2 on the tip, followed by transfer of atoms to the surface is the proposed mechanism of these tip-catalyzed reactions.

SSZ-24 forms in the presence of potassium cations, and SSZ-31 crystallizes in the presence of sodium cations. This is the first report of SSZ-31 synthesis from Na-TMAA silicate mixtures. Unknown silicates form in the presence of rubidium and cesium cations, whereas no crystalline material is observed in synthesis mixtures devoid of alkali cations. The alkali cations do not appear to serve as templates or void fillers during zeolite crystallization, nor do they stabilize soluble silicate anions which serve as building blocks during zeolite crystallization. Rather, the alkali cations appear to regulate the transformation of the amorphous synthesis gel into either crystalline zeolite or other silicate phases.

Characterization of the surface composition and structure was determined in UHV using low energy electron diffraction (LEED), Auger electron spectroscopy (AES), and low energy ion scattering (LEIS) prior to determining the electrode kinetics using the classical rotating disk method (RDE) with CO dissolved in the electrolyte. Clean annealed and sputtered-cleaned but not-annealed surfaces of (110) and (111) orientation were studied. A remarkable difference in activity was observed between the annealed(lll) surface and the sputtered but not-annealed (110) surface, with both surfaces having the same nominal surface composition, 20-25 at% Sn, but different local structures. The onset potential for CO oxidation on the (111) surface was shifted cathodically by 0.13 V relative to that for the sputtered (110) surface, and the onset comes remarkably close to 0 V on the reversible hydrogen potential scale. Relative to pure Pt surfaces (of any crystal structure), the potential shift is more than 0.5 V, corresponding to a catalytic activity that is higher by more than four orders of magnitude. Comparable shifts were observed for the oxidation of CO/H-2 mixtures. Both the structure sensitivity and the high catalytic activity of the Pt3Sn surface are attributed to an adsorbed state of CO unique to this alloy and occurs at relatively high coverage on the (111) surface.

It has been proposed that activation of methane occurs via reaction with peroxide species present at the surface of the catalyst. In the present work, Raman spectroscopy has been used to investigate the formation, decomposition, and reduction of BaO2 on 4 mol% Ba/MgO. The presence of BaO2 is evidenced by the presence of a band at 842 cm(-1). The peroxide forms above 300 degrees C but is stable to decomposition at temperatures up to 500 degrees C. Reduction of BaO2 to BaO proceeds via Ba(OH)(2). BaCO3 forms when either BaO or BaO2 is exposed to CO2. Once formed, BaCO3 is stable to decomposition in He or O-2 at temperatures up to 500 degrees C. Only BaCO3 is observed when a mixture of CH4 and O-2 is passed over the catalyst at 500 degrees C. C1 UNIV CALIF BERKELEY,DEPT CHEM ENGN,BERKELEY,CA 94720.

These techniques enable material microstructure parameters and surface areas to be measured nondestructively, and have been applied to study the effects of different sintering temperatures, pressures and additives. Depending on the sintered density, the scattering data from nanophase materials exhibit Pored scattering associated with the high surface area, scattering from the nanometer-size grains and pores, and interparticle interference scattering. By using samples of sufficient size and uniformity to permit absolute calibration of the scattering data, it has been possible to develop a fully quantitative microstructure model. Studies of nanophase yttria (powder, prepared by Nanophase Technologies Corporation, Burr Ridge, IL) and zirconia (powder, prepared at Rutgers University, Piscataway, NJ) are discussed, and it is shown how small-angle scattering, in conjunction with density measurements, electron microscopy and X-ray diffraction, provides a unique probe of the statistically representative microstructures present in these novel materials.

In this article, examples of superplastic forming and diffusion bonding of ceramic components are given. Recent work in biaxial gas-pressure forming of several ceramics is provided. These include yttria-stabilized, tetragonal zirconia (YTZP), a 20% alumina/YTZP composite, and silicon. In addition, the concurrent superplastic forming and diffusion bonding of a hybrid ceramic-metal structure are presented. These forming processes offer technological advantages of greater dimensional control and increased variety and complexity of shapes than is possible with conventional ceramic shaping technology.

The event was detected locally by a security video camera which showed the reflection of the fireball event on the hood of a truck. The camera also recorded tree shadows cast by the light of the fireball. This recording includes the audio signal of a strong double boom as well. Subsequent investigation of the array near Los Alamos, New Mexico operated by the Los Alamos National Laboratory as part of its commitment to the Comprehensive Test Ban Treaty negotiations, showed the presence of an infrasonic signal from the proper direction at about the correct time for this fireball. The Los Alamos array is a four-element infrasonic system in near-continuous operation on the laboratory property. The nominal spacing between the array elements is 212m. The basic sensor is a Globe Universal Sciences Model 100C microphone whose response is flat from about 0.1 to 300 Hz (which we filter at the high frequency end to be limited to 20 Hz). Each low frequency microphone is connected to a set of twelve porous hoses to reduce wind noise. The characteristics of the observed signal include the onset arrival time of 0939:20 UT (0239:20 MST), with a maximum timing uncertainty of +/- 2 minutes, the signal onset time delay from the appearance of the fireball of 21 minutes, 20 seconds, total signal duration of 2 minutes 10 seconds, the source location determined to be toward 31 degrees from true north, the horizontal trace velocity of 429 m/sec, the signal velocity of 0.29 +/- 0.03 km/sec, assuming a 375 ion horizontal range to the fireball, the dominant signal frequency content of 0.25 to 0.84 Hz (analyzed in the frequency interval from 0.2 to 2.0 Hz), the maximum signal cross-correlation of 0.97 and the maximum signal amplitude of 2.0 +/- 0.1 microbars. Also, on the basis of the signal period at maximum amplitude, we estimate a probable source energy for this event of between 10 to 100 tons of TNT (53.0 tons nominal).

Both require a source of well characterized hypervelocity particles. Electrostatic acceleration of charged microspheres provides such. a source. Techniques refined at the Los Alamos National Laboratory provided information On hypervelocity impacts of particles of known mass and velocity ranging from 20-1000 nn diameter and 1-100 km/s. A Van De Graaff generator operating at 6 million volts was used to accelerate individual carbonyl iron microspheres produced by a specially designed particle source. Standard electrostatic lenses and steering were used to control the particles flight path. Charge sensitive pickoff tubes measured the particle charge and velocity in-flight without disturbing the particle. This information coupled with the measured Van De Graaff terminal voltage allowed calculation of the particle energy, mass, momentum, and using an assumed density the size. Particles with the desired parameters were then electrostatically directed to a target chamber. Targets used in our experiments included cratering and foil puncture targets, microphone momentum enhancement detectors, triboluminescent detectors, and 'splash' charge detectors. In addition the system has been used to rapidly characterize size distributions of conductive plastic particles and potentially provide a method of easily sorting microscopic particles by size.

The SAM used in this application was 11-mercaptoundecanoic acid (MUA) assembled from a 5-mM solution in ethanol onto the inner surfaces of silvered Pyrex(R) glass tubing (4-mm inside diameter x 21-cm length). The sensor was adapted with minor modifications to fit standard fiber-launching and detection optics, which incorporate a remote cryogenic detector and mate to a Fourier transform infrared (FTIR) spectrophotometer. The f1.5 optics allow a sufficient number of multiple reflections inside the sensor to achieve spectroscopic sensitivity to the SAM within a 15 minute measurement time at 2 cm(-1) resolution. The overall optical configuration is similar to that of the waveguides used for gas chromatography (GC)-FTIR spectroscopy, except that the inner surface of the sensor, rather than the gas contained in the GC-FTIR waveguide, is sampled. After the FTIR spectrum of a freshly prepared sensor is recorded, the inner surface (functionalized with carboxylic acid) is exposed to an ambient or flowing atmosphere. The terminal acid groups exposed at the surface of the MUA SAM react with basic pollutants, such as amines, which can be indoor air pollutants. The spectrum of the exposed sensor is then recorded and ratioed to the original sensor spectrum to produce an absorbance spectrum characteristic of the reacted, surface-bound pollutant. Our sensors exhibited sensitivity to 15 ppm of octylamine in an ambient atmosphere after 2 hours of exposure at 36 degrees C.

These simulations build on a previously described mechanism in which pair-wise, far-field, hydrodynamic interactions between swimming bacteria are proposed to be responsible for the band structure that appears when such bacteria are oriented in a given direction by an external magnetic field. Previous work has shown that these hydrodynamic forces act in a direction and with a magnitude that are fully consistent with the observed behavior. Applying this pair-wise, hydrodynamic force mechanism to hundreds of bacteria in a numerical simulation shows that band formation and stability is predicted by this simple model, while the precise band shape appears to depend on effects not included in the simulation.

This highly ordered structure has eight polyhedral bubbles in the unit cell: two pentagonal dodecahedra and six tetrakaidecahedra with twelve pentagonal faces and two hexagonal faces. Both dodecahedra have equal volume and all of the tetrakaidecahedra have equal volume, but these volumes are different for the bidisperse structures considered here. These volume constraints preserve the cubic symmetry of the Weaire-Phelan structure so that the elastic response is completely characterized by a bulk modulus kappa for volume compression and two shear moduli mu(1) and mu(2). The shear moduli can be combined to obtain an effective isotropic shear modulus <(mu)over bar>, which represents the shear response averaged over all orientations of the foam. For the monodisperse case, <(mu)over bar> = <0.8684T(V)over bar>(-1/3), where T is surface tension and (V) over bar is the average bubble volume. For bidisperse structures, <(mu)over bar> never differs from the monodisperse case by more than 0.5% and the mu(i) always lie within 4% of <(mu)over bar>. The pressure inside the dodecahedra is always greater than the pressure inside the tetrakaidecahedra even when the dodecahedra are larger.

The suspensions are well mixed and homogeneous in the sense that the particles are well dispersed and the rods are randomly oriented. For a constant total volume fraction of solids, the addition of spheres to suspensions of rods results in large decrease in the relative viscosity of the suspension. In these experiments the length of the suspended rods is approximately 10 times the diameter of the suspended spheres. Due to this difference in the characteristic sizes of the two types of particles, the spheres may be considered as part of the suspending homogeneous continuum. A simple model based on this physical picture, after Farris [1968], is very successful in predicting the relative viscosity of the mixed suspensions.

Thus, wave motions on the rotationally stabilized cylindrical interfaces can occur in natural and technological processes, notwithstanding the lack of coherent treatment in the literature. This work provides a supplementary linear analysis of various wave motions in a three-dimensional framework for two-phase inviscid fluid systems with cylindrical interfaces stabilized by rotation. Many previous results found in the literature are recast in a general from. With gravity acting perpendicularly to the rotation axis, the interface disturbance is considered as an externally forced wave motion. The condition for the stability of the gravity-induced interface displacement in a two-phase rotating system is found to be exactly the same as that for the one-phase case such as an air column in a rotating liquid.

Radicals and radical ions created by the laser excitation at 308 nm were detected by means of time-resolved pulsed electron paramagnetic resonance (EPR). The results are consistent with the involvement of the excited triplet state which ionizes or abstracts H atom from the solvent. This short-lived state was identified through the sign of multiplet spin polarization in radical pairs. A triplet mechanism polarization in relatively polar alcohols (such as 2-propanol and cyclohexanol) was observed. In less polar alcohols (octanol, decanol) the H abstraction seems to be the major reaction route. Contrary to Mural et al. we did not find any evidence for singlet-correlated radical ion pairs with J > 0. C1 ARGONNE NATL LAB,DIV CHEM,ARGONNE,IL 60439.

The mobile circuit was field tested at a copper mine with solutions containing from 120 ppm up to 1.4 g/L Cu. The solutions were representative of mine waste waters and various low-grade leach solutions. The LEM system used simple equipment designs for all units. The formulation of the emulsion membranes were optimized so that the emulsions had good stability during extraction, but were easily broken in an electrical coalescer using mild conditions. Typical results from the tests were >90 percent copper recovery while maintaining membrane swelling in the range of 4 to 8 percent. Although all of the mine solutions contained high impurity levels and suspended solids, pure copper cathodes were produced from each solution. Cost evaluations indicated the potential for the cost-effective recovery of copper from the solutions treated.

The free base forms of the porphyrins were also added to samples of Cu(II)- and Fe(III)-montmorillonites. X-ray absorption spectroscopy (XAS), both X-ray absorption near-edge structure (XANES) and extended X-ray absorption fine structure (EXAFS), were used to monitor the fate of the metal ions. The Cu(II)-metalloporphyrins do not demetalate upon contact with the acidic montmorillonite support. The XAS data also suggest that Fe(III)-porphyrin complexes are stable on smectite supports. XANES data demonstrate that the free base porphyrin TTAP metalates on the surface of a Cu(II)-exchanged clay to form a stable Cu(II)-porphyrin-clay complex.

The substitution formally creates a charge deficiency on the Ti site. To compensate for this, we have substituted aliovalent counterions on the titanium (Nb), phosphorus (S, Se, Cr, Mo, W, Re), oxygen (F), or potassium (Ca, Sr, Pa, Pb) sites. The resulting new materials expand the KTiOPO4 structure field for partial replacement of one or more ions. The M and Ln ions alter the optical absorption and second harmonic properties of the materials. The ions reduce the second harmonic intensities of the isomorphs (measured at 532 nm) but improve their phase-matching capabilities, allowing fundamental and second harmonic radiation to be phase matched at slightly shorter wavelengths than in the undoped host.

The related complex {Cu[mu-OSiPh(O(t)Bu)(2)]}(4) (4), obtained similarly, was characterized by X-ray crystallography as having a planar Cu4O4 core with oxygen-bridged Cu atoms. The highly associated, sublimable {NaCu[OSi(O(t)Bu)(3)](2)}(6) (3) was obtained by the addition of NaOSi(O(t)Bu)(3) to 1 or by reaction of 2 equiv of NaOSi(O(t)Bu)(3) with CuCl. Thermogravimetric analysis (TGA) of 1 under both oxygen and argon reveals rather sharp, low-temperature conversions to the final ceramic compositions (onset temperatures: ca. 100 degrees C under oxygen; ca. 150 degrees C under argon). Under argon, the resulting material consists of Cu-0 and Cu2O nanoparticles dispersed in silica, whereas an oxygen atmosphere leads to CuO nanoparticles in silica. These materials are carbon- and hydrogen-free and are produced by elimination of isobutene, tert-butyl alcohol, water, and silanol. The pyrolytic conversion of compound 4 occurs at higher temperature and more gradually but gives relatively clean conversion to a CuO/SiO2 composite under an oxygen atmosphere. The volatility of 1 allows its use in CVD preparations of thin films. Amorphous thin films with a Cu/Si ratio of 1:0.85 (microprobe analysis) and thicknesses ranging from 200 nm to 6 mu m have been obtained.

Dense, nanocrystalline, iron hydroxide films were deposited onto sulfonated polystyrene and sulfonated self-assembling monolayers on oxidized silicon. (020) oriented goethite films were formed resulting in chains of edge-shared octahedra in the [001] direction lying parallel to the surface. Deposition amounts varied with pH primarily due to changes in solution supersaturation. The best films were formed when deposition occurred heterogeneously at supersaturations just below the critical supersaturation. Induction times decreased with increasing sulfonate site density due to a reduction in interfacial energy. Nucleation was initiated by binding of cationic species to sulfonate sites and hydrolysis and condensation reactions resulted in the growth and coalescence of crystallites.

It has been observed in the centromeric regions of mitotic chromosomes of mouse or human origin when cells are grown in 5-bromo-2'-deoxyuridine (BrdU) for a single round of DNA synthesis. The chromosome-orientation fluorescence in situ hybridization (GO-FISH) technique was used with pseudodiploid mouse cells to show that the regions of asymmetrical brightness coincide with major satellite repetitive DNA, and that the more heavily BrdU-substituted chromatid is the one that fluoresces less brightly. These observations support a 20 year old hypothesis on the origin of lateral asymmetry. Other observations suggest that differential loss of DNA from the heavily substituted chromatid also contributes to lateral asymmetry.

In addition to the temporal variation of the large-scale flow, local topography played a crucial role in the simulated precipitation and land-surface snow budget through orographically-generated vertical motion and a decrease of atmospheric temperature with increasing altitude. The observed and simulated heavy precipitation occurred at locations where orographic lifting is strong: western slopes of the Sierra Nevada Mountains and the Coastal Range. Due to rainshadow effects, the Central Valley area, which is located at the lee side of the Coastal Range, received only a small amount of precipitation. The snowline appeared at altitudes as low as 750 m above sea level, and most of the precipitation above the 1.8 km level was snow. Maximum rainfall was located near the 1 km elevation along the western slope of the Sierra-Nevada while snowfall maxima appeared along the ridge of the Sierra Nevada Mountains. Snow accumulation was also strongly dependent upon surface elevations. The simulation suggested that over 75% of the fresh snowfall during the study period was added to the existing snow cover at elevations above 1.5 km while much of the snowfall over lower elevations melted.

Despite its importance in the design of industrial burners, no systematic and detailed fundamental study of flame confinement has been attempted. As a result, a data gap exists in an area important to burner design. To fill this data gap, we have performed a comprehensive test program that included several bluff-body burners, with different confinements and air jet sizes. This paper presents some of the velocity and fuel concentration data, obtained for four Blockage Ratios (BR). The velocity data were obtained by laser Doppler velocimetry and the concentration data were obtained by Raman imaging. The effect of confinement on velocity and concentration fields, and dame stability are analyzed. It is shown that, for the low BR case, recirculation zone characteristics and flame stability are unaffected by confinement. In contrast, confinement increases the recirculation zone size, distributes the fuel over a larger volume and enhances the stability of the high BR flames. To demonstrate a practical application of the data, concentration results are used to predict complex bluff-body flame regimes. C1 ALTEX TECHNOL CORP,SANTA CLARA,CA 95054. GAZ FRANCE,ST DENIS,FRANCE.

Here we apply ELFFS to lead, manganese, nickel and chromium species in the postflame gases of a laboratory burner. Using a 193-nm argon fluoride laser we obtain quantitative relationships between signal strength and concentration in hot combustion products for metals injected into a flame; representative spectra are shown. The effects of quenching environment and laser power on the signal are discussed. The ELFFS technique is sensitive, providing ppb detection limits for these metals in a one-second measurement time.

An atmospheric pressure, laminar flat flame operated at an equivalence ratio of 2.5 was used to acquire experimental data for model validation. Gas composition analysis was conducted by an on-line gas chromatograph / mass spectrometer technique. Measurements were made in the flame and post-flame zone for a number of low molecular weight species, aliphatics, aromatics, and polycyclic aromatic hydrocarbons (PAHs) ranging from two to five-aromatic fused rings. The modeling results show the key reaction sequences leading to aromatic and polycyclic aromatic hydrocarbon formation primarily involve the combination of resonantly stabilized radicals. In particular, propargyl and 1-methylallenyl combination reactions lead to benzene and methyl substituted benzene formation, while polycyclic aromatics are formed from cyclopentadienyl and fused rings that have a shared C-5 side structure. Naphthalene production through the reaction step of cyclopentadienyl self-combination, and phenanthrene formation from indenyl and cyclopentadienyl combination were shown to be important in the flame modeling study. The removal of phenyl O-2 leading to cyclopentadienyl formation is expected to play a pivotal role in the PAH or soot precursor growth process under fuel-rich oxidation conditions.

Flame structure was also evaluated by means of visible emission imaging. Excess air was varied from 50% to sub-stoichiometric. The fuels were methane and blends of methane, hydrogen, and propane used to simulate the process gas burned in refineries. Each fuel was tailored so that the inlet and boundary conditions on the flame were invariant between fuels-minimizing fluid mechanic differences. The results show emission levels < 3 ppbv for toluene and < 0.5 ppbv for the other species under normal firing conditions. This is in contrast to emissions from 10 to 150 ppbv observed in refinery field tests (WSPA, 1994). They also show an increase in emissions with fuel hydrogen and propane contents. Under sub-stoichiometric conditions, emissions increase by orders of magnitude, with benzene replacing toluene as the dominant emission. C1 SANDIA NATL LABS,COMBUST RES FACIL,LIVERMORE,CA 94551.

The experiments consisted of the temporary release of a particle laden stream into a cross flow, and the subsequent visualization of the concentration field using laser sheets or laser lines. Quantitative data, including average concentration and concentration fluctuation profiles, were obtained from video frames by digital image analysis. The experiments were compared to a computer simulation model, based on the linear eddy modeling technique. Model results agreed very well with experimental data, if a recirculation zone was explicitly accounted for. This study suggests that gas phase unmixedness is a likely explanation for failure modes in rotary kiln incineration. Insufficient macro-mixing (controlled by transient evaporation and large scale motion) is more important than local unmixedness (governed by fine scale turbulence and molecular diffusion), although both processes play a role. Linear eddy model simulations also showed that low resolution measurements of mixing with large Schmidt numbers (i.e. for particles) can be interpreted as fully resolved mixing with Schmidt number equal to unity (i.e. for gases).

Comparisons are made between measurements and computations for flames of pure fuel, fuel premixed with CF3Br and for flames of pure fuel with the surrounding air premixed with CF,Br. The measurements of temperature and the concentration of many stable species including HF, HBr and CF3Br as well as the hydroxyl radical, OH are made in axisymmetric flames using the Raman-Rayleigh-LIF technique. Calculations are performed for laminar counterflow nonpremixed flames using complex chemistry and detailed transport properties. It is found that the addition of halon-1301 increases the peak temperature of the flame and causes little change in the concentrations of stable species. However, the minor species and flame radicals are significantly affected. The rate of decomposition of CF3Br is not well predicted and significant discrepancy exists in the computations of halon related species. Unreliable chemical kinetic rates and experimental error particularly on HF and HBr appear to be the major contributing factors. C1 SANDIA NATL LABS, COMBUST RES FACIL, LIVERMORE, CA 94550 USA.

This baroclinic push on the dame differs from the axial pressure model suggested by Chomiak (1976). In particular, the baroclinic enhancement will depend upon the location of the burnt gas with respect to the flame, as shown by two Vortex configurations: straight and curved. Additionally, the baroclinic effect, depending upon the flame density gradient and the swirling dow radial pressure gradient, will provide an enhancement that is proportional to the ambient pressure.

The method is based on the balance of conditional mass fluxes in a control volume that extends from pure reactants to the stagnation plane. The principle is that the difference between the mass of reactants flowing into and out of the control volume is the mass that has reacted within the control volume. Similarly, if only reactants flow into the control volume then the mass flow rate of products out of the control volume constitutes the burning rate in that region of the flame. The measurement techniques necessary to use this approach are all available. Experimental measurements were conducted on the stagnation plate geometry. The burning rate characterized by a leading edge velocity overestimated the value determined from the conditioned mass fluxes by 41%. The extension of this approach to other burner geometries and more general flame shapes is discussed and suggestions for its use in rod stabilized flames are made. In this case the shape and orientation of the control volume are set by the maximum gradient in space of the progress variable. For curved flame zones and more general flows the choice of control volume remains ambiguous. C1 UNIV CALIF BERKELEY,LAWRENCE BERKELEY LAB,DIV ENERGY & ENVIRONM,COMBUST GRP,BERKELEY,CA 94720.

The technique takes advantage of the unique properties of carbonyl and cyanide stretching vibrations, including high infrared oscillator strength and well established sensitivity of vibrational frequency, intensity, and bandwidth to electronic and molecular structure. Electronic excitation generally produces significant transient infrared absorption changes which are characteristic of the changes in electronic structure, such as oxidation of the metal. TRIR spectroscopy thus provides new insight on the nature of the excited state transition (e.g. charge transfer vs. ligand centered), the extent of charge transfer, communication between metal centers, and energy and electron transfer processes. The step-scan FTIR approach has significant advantages over conventional time-resolved techniques, including spectral multiplexing, increased IR throughput, and fast data acquisition, making it possible to rapidly obtain complete spectra with good sensitivity and time-resolution.

The authors explain the basis of the method, namely stabilization via wisely chosen inner steps (stages), justify it for linear problems, and spell out how simple it is to incorporate in any explicit code for parabolic problems. Finally, we demonstrate its performance on the (linear) heat equation as well as on the (non-linear) classical Stefan problem, by comparing it with standard implicit schemes (employing SOR or Newton iterations). The results show that super-time-stepping is more efficient than the implicit schemes in that it runs at least as fast, it is of comparable or better accuracy, and it is, of course, much easier to program (and to parallelize for distributed computing).

Specifically, the toughening of these materials is largely attributed to the energy dissipation due to the frictional sliding of fibers at their interface with the matrix material. The micromechanisms involved with interfacial failure and sliding are currently not entirely understood, and the failure threshold is generally predicted using macro-scale friction laws which neglect the micromechanical aspects. The objective of this study is to explore the derivation of a macro-scale static coefficient of friction at the interface of a previously debonded fiber based on the micro-scale properties of the contacting surfaces. Presented results illustrate that the macro-scale static coefficient of friction obtained from the proposed micro-scale model is independent of the normal load and is therefore consistent with the classical Amontons-Coulomb phenomenological laws of friction.

Auger electron spectroscopy was then used to examine the fiber/matrix interface and locate the path of interface debonding. Single-fiber-push-out experiments were used to quantify the mechanical properties of the fiber/matrix interface. The bulk composite fracture properties were consistent with current understanding in that a lower interfacial toughness was found to enhance fiber pull-out and increase the composite toughness. Matrix abrasion during fiber sliding had a significant effect on the sliding behavior of the fibers.

For B>1.9T applied in the direction parallel to the growth direction, luminescence peaks from the lowest Landau-level from the second subband are pronounced and show intensity oscillations nearly periodic with the inverse magnetic field. Self-consistent Landau-level calculations indicate that both the population of the second subband and the energy gap between Landau levels from this and the first subband reveal nearly periodic oscillations in inverse magnetic field. Oscillations in the luminescence intensity can be explained by the effect of population oscillations in the second subband. C1 NORTHEASTERN UNIV,BOSTON,MA 02115.

These properties arise from the combined effect of B-parallel to-induced relative displacement of the wave vectors in the two QWs and the interwell tunneling. In weakly coupled DQWs, the tunneling conductance has two sharp maxima as a function of B-parallel to. In strongly coupled DQWs, a partial minigap is formed due to the anticrossing of the two QW dispersion curves, yielding sharp B-parallel to-dependent structures in the density of states and in-plane transport properties. Excellent agreement is obtained between the theory and the data from GaAs/AlGaAs DQWs. RP Lyo, SK (reprint author), SANDIA NATL LABS, POB 5800, ALBUQUERQUE, NM 87185 USA.

The important properties of a program for the efficient generation of derivative code are the asymmetries between the number of inputs and outputs of program components at various levels of abstraction and the mathematical complexity of the involved operators. Automatic generation of efficient derivative codes thus requires analysis of programs for detection of such properties and systematic methods for their exploitation in composing the derivative codes. We suggest a hierarchical approach based on a partitioning of the computational or program graph as a means to deduce workable solutions to this hard problem. Each partition corresponds to a localized scope for derivative computation, and hierarchical partitions provide a mechanism for exploiting program structure at various levels. As a particular example, we discuss dynamic programming approaches for finding good one-dimensional partitions and generalizations to arbitrary directed acyclic graphs that, by recycling substructure information, allow one to determine the optimal elimination ordering for a graph with n nodes with complexity O(2(n)), as compared with the O(n!) complexity of a naive search. Lastly, we give a concrete example illustrating the hierarchical approach on the driven cavity problem from the MINPACK-2 optimization test set collection.

The method employs the usual series for the matrix (I-A)(-1) to obtain an expansion in which the zeroth order term is an isotropic fundamental solution. The higher order contributions are expressed as contour integrals of matrix products, and can be directly evaluated with a symbolic manipulation program. A convergence condition is established for cubic crystals, and it is shown that convergence is enhanced by employing Voigt averaged isotropic constants to define the expansion point. Example calculations demonstrate that, for moderately anisotropic materials, employing the first few terms in the series provides an accurate solution and a fast computational algorithm. However, for strongly anisotropic solids, this approach will most likely not be competitive with the Wilson-Cruse interpolation algorithm.

This single motion assumption is violated in common situations involving transparency, depth discontinuities, independently moving objects, shadows, and specular reflections. To robustly estimate optical flow, the single motion assumption must be relaxed. This paper presents a framework based on robust estimation that addresses violations of the brightness constancy and spatial smoothness assumptions caused by multiple motions. We show how the robust estimation framework can be applied to standard formulations of the optical flow problem thus reducing their sensitivity to violations of their underlying assumptions, The approach has been applied to three standard techniques for recovering optical flow: area-based regression, correlation, and regularization with motion discontinuities. This paper focuses on the recovery of multiple parametric motion models within a region, as well as the recovery of piecewise-smooth flow fields, and provides examples with natural and synthetic image sequences.

This procedure can be extended to continuous processes that have repeated upsets or perturbations. The MSPC technique was demonstrated for a nuclear waste storage tank that undergoes periodic agitation from a mixing pump. The procedure described here used multi-way principal components analysis to develop a statistical model of the process based on historical data. The model can be used to determine if changes have occurred in the system. At present this procedure is used off-line for monitoring but it could be implemented on-line.

The amount of glass produced can be reduced by blending of the wastes. The optimal way to combine the tanks to minimize the volume of glass can be determined from a discrete blend calculation. However, this problem results in a combinatorial explosion as the number of tanks increases. Moreover, the property constraints make this problem highly non-convex where many algorithms get trapped in local minima. In this paper we examine the use of different combinatorial optimization approaches to solve this problem. A two stage approach using a combination of Simulated Annealing and nonlinear programming (NLP) is developed. The results of different methods such as heuristics approach based on human knowledge and judgment, mixed integer nonlinear programming (MINLP) approach with GAMS, and branch and bound with lower bound derived from the structure of the given blending problem are compared with this coupled Simulated Annealing and NLP approach.

We have created a Virtual Biomolecular Environment (VIBE), which consists of (1) massively parallel computing to simulate the physical and chemical properties of a molecular system, (2) the Cave Automatic Virtual Environment (CAVE) for immersive display and interaction with the molecular system, and (3) a high-speed network interface to exchange data between the simulation and the CAVE. VIBE enables molecular scientists to have a visual, auditory, and haptic experience with a chemical system, while simultaneously manipulating its physical properties by steering, in real-time, a simulation executed on a supercomputer.

In this article, a mathematical model of the fuel handling system is described which predicts the system's performance under different fuel handling scenarios. In particular, the following two scenarios are studied: (a) a feasible fuel handling schedule to unload 330 blanket S/A in a period of 3 yr with minimal interruption to the normal operation of the reactor; and (b) a feasible fuel handling schedule to shut down and unload the reactor and the storage tank. In addition, the interactions between different sub-systems are highlighted and the results of different sensitivity analysis, performed to scrutinize the system's capability under different constraining procedures are reviewed.

Nuclear weapons remain a key element of the nation's strategic deterrent policy although their number in the stockpile is being reduced dramatically. On August 11, 1995, the President announced his decision to seek zero-yield comprehensive test ban treaty. Prior to his announcement, the President was assured by the Department of Energy Secretary and the directors of the three nuclear weapons laboratories that a robust Science-Based Stockpile Stewardship program could be established to maintain a sufficiently high level of confidence in the safety and reliability of the nation's nuclear stockpile. This paper describes the major pulsed power accelerator initiatives within the national Science-Based Stockpile Stewardship program.

The present tests were conducted to measure the early-time turn-on characteristics of ABB 2003-45A02 thyristors and to determine whether special triggering techniques could raise the safe turn-on rate to the 100,000 A/mu s range which would qualify it for applications such as direct drive accelerator circuits. Results were encouraging. With these devices and special triggering techniques a maximum turn-on rate of 65,373 A/mu s and a peak current of 19,040 A were recorded at a pulse repetition rate of 5 Hz.

Depending on the ion implantation process recipe, various repetition rates, pulse widths, and currents are required. In addition, the cathodic are system may be synchronized with a higher voltage ''target'' modulator system. The cathodic are is water cooled and usually uses a self generated axial B-field, by use of a series connected solenoid around the are anode. Typical are currents of 800 amperes may be utilized with pulse widths ranging from 20 uS to 4 mS. Typical PRF's may exceed 400 Hz, with overall system power limited by our presently available 10 kW transformer-rectifier. The cathodic are modulator system consists of a command charged 10 kV trigger generator, a high voltage are ''starter'', and a low voltage, high current are sustain circuit. The are start and sustain circuits are independently adjustable and utilize a common IGBT device in a ''hot-deck'' configuration. This paper will provide circuit design and performance information in addition to various process applications. RP Reass, WA (reprint author), LOS ALAMOS NATL LAB,POB 1663,LOS ALAMOS,NM 87545, USA.

Therefore, for operating stresses in the corona regime, activity typically increases with time and, if allowed to continue, eventually leads to breakdown of the oil and failure of the component or system. It is, therefore, common practice to periodically replace oil in devices such as large power transformers and switch gear before breakdown occurs. Sealed components such as capacitors are typically replaced. RP Rohwein, GJ (reprint author), SANDIA NATL LABS,MS-1153,POB 5800,ALBUQUERQUE,NM 87185, USA.

This type of direct time domain radar is uniquely suited for observation of large structures under ground because it can operate at low frequencies and at high average power. This paper will summarize the state-of-the-art in,high gain GaAs switches and discuss their use in a radar transmitter. We will also present a summary of an analysis of the effectiveness of different pulser geometries that result in transmitted pulses with varying frequency content.

Output rise times are typically in the 10ns to 20ns range, often making it necessary to synchronize to within less than Ins. Microprocessor and electronic feedback schemes have been developed and demonstrated(1-6) that achieve the required level of synchronization, however, they are sophisticated and potentially complex. In a quest for simplicity,this work seeks to determine the achievable level of modulator to modulator timing jitter that can be obtained with simple design practices and passive techniques. Sources of output pulse time jitter in magnetic modulators are reviewed and some basic modulator design principles that can be used to minimize the intrinsic time jitter between modulators are discussed. A novel technique for passive synchronization is presented. RP Reed, KW (reprint author), SANDIA NATL LABS,POB 5800,ALBUQUERQUE,NM 87185, USA.

It is found that values of f(H2O) Should be valid for the range from 0.0 to 0.3 and probably to 0.4 in mole fraction NaCl for temperatures from 300 degrees to 600 degrees C and less accurately to 900 degrees C. Comparison is made with existing experimental results near 630 degrees C for the dehydration of brucite; the agreement is excellent. Comparison with recent results at 850 degrees C from a different experiment is also satisfactory. However, fugacity of NaCl is not given on an absolute basis, even in this range below x(NaCl)=0.4.

Measurements cover the divertor radially from inside the X-point to the outer target plate and vertically from the target plate to above the X-point. Identical, repeatable shots were made, each having radial sweeps of the X-point and divertor strike points, to allow complete plasma and radiation profile measurements. Data have been obtained in ohmic, L-mode, ELMing H-mode, and reversed B-T operation (del B drift away from the X-point). In addition, complete measurements were made of radiative divertor plasmas with a Partially Detached Divertor (PDD) induced by D-2 injection and with a Radiating Mantle induced by Impurity injection (RMI) using neon and nitrogen. The data set includes first observations of the radial and poloidal profiles of the X-point, inner and outer leg plasmas in PDD and RMI radiative divertor operation. Preliminary data analysis shows that intrinsic impurities play a critical role in determining the SOL and divertor conditions. C1 GEN ATOM CO,SAN DIEGO,CA. SANDIA NATL LABS,LIVERMORE,CA.

It features a parallel neutral momentum equation, fully coupled to the ions, allowing parallel plasma momentum to be converted into neutral momentum, which is dispersed to the material walls due to the high neutral viscosity. The simulations reproduce the pervasive experimental feature that the plasma detaches gradually, starting at the strike point, while always remaining attached above the nose of the divertor channel. The strike point heat flux and current drop by an order of magnitude as 0.5% of carbon is introduced to induce partial detachment. The plate temperature remains at or above about 1 eV all the way out to the divertor nose, in agreement with the experimental data. C1 IDAHO NATL ENGN LAB,IDAHO FALLS,ID 83415.

On the other hand, some of the current experimental observations imply that such perturbations do exist. In the present paper we consider possible resolutions of this apparent paradox for some specific experimental situations: short divertor legs; presence of a cold plasma in the divertor legs; and excitation of the modes with small toroidal wave numbers.

The nonlinear evolution of edge turbulence in the electrostatic limit is described by a four-field model of the reduced Braginskii equations in a model x-point geometry, including drives for the (1) conducting-wall mode, (2) Kelvin-Holmhotz mode, (3) curvature-driven mode, (4) del(x) upsilon(parallel to)-driven mode, and (5) axial shear mode. In a detached plasma with T-e0/T-ed = 50 and N-e0/N-ed = 0.2, and without magnetic shear, we find that a conducting-wall-like mode is the dominant drive even if turbulence drive from the sheath is small.

What makes these properties quite different from those of ''standard'' Debye sheaths is that the magnetic field in the SOL intersects divertor plates at a shallow angle. The survey covers the following issues of the sheath physics in an magnetic field: sheath structure and particle trajectories; effect of diamagnetic and drifts on the current-voltage characteristics of the sheath; effect of the surface ''roughness'' and ''waviness'' on sheath properties and plasma transport; possible role of the anomalous transport, etc. The second class of objects briefly discussed in the present survey are shock waves which can appear in the divertor region if the incoming plasma flow is supersonic. The outline of the kinetic theory of impurity retention by the shocks is presented. RP LAWRENCE LIVERMORE NATL LAB, LIVERMORE, CA 94550 USA.

High plasma density causes a strong energy loss due to impurity radiation peak in this low temperature region. For low Z impurity the energy transport due to plasma convection and neutrals also can strongly influence the volume of low temperature region. C1 IV KURCHATOV ATOM ENERGY INST,MOSCOW 123182,RUSSIA.

We take into account different atomic processes (vibrational excitation of molecular hydrogen, electron dissociative attachment, ion conversion, charge exchange and dissociative recombinations, dissociation and ionization, etc.) and find the expression for the effective plasma recombination rate constant from a suitably reduced set of coupled rate equations. We estimate the influence of the recombination process on divertor plasma behavior and find that for AlcatorC-MOD like parameters plasma recombination due to negative and molecular ions becomes significant in the temperature range below a few eV. We conclude that plasma recombination is a strongly contributing mechanism for the explanation of divertor plasma detachment in low temperature plasmas.

A short mean free path neutral-plasma model of the divertor region below the x-point is adopted in which all perpendicular transport is due to the neutrals.

For fluid modelling of plasmas, a common remedy is to apply an artificial ''flux limiter'' that keeps the heat flux at a physically reasonable value in this long mean-free-path regime. The ad-hoc limiter is not derived from first principles and it introduces a poorly understood free parameter into the model. We study the effect of this parameter in our divertor plasma models to understand how it influences the computed solution. We investigate regimes of both short and long mean-free-path and consistently find large parameter sensitivity. Thus, without additional experimental or theoretical guidance in the choice of flux-limit parameter, flux limiting does not appear to provide an acceptable basis for predictive plasma fluid modelling.

The phenomenon (coined as high strain rate superplasticity, HSRS) was often found to be associated with the presence of a liquid phase. For example, the tensile elongation to failure, strain rate sensitivity, and activation energy in a material exhibiting HSRS are observed to be dependent upon the testing temperature. Specifically, marked changes in these properties are closely related to incipient melting points in the materials. These observations suggest that the presence of a small amount of liquid phase at interfaces or grain boundaries not only enhances the strain rate for superplasticity, but also has a strong influence on the deformation and fracture mechanisms. When the amount of liquid phase increases, as a result of increasing temperature, the expected observation is noted i.e. the presence of the liquid phase degrades the material properties. There exists a critical amount of liquid for the optimization of tensile elongation. In this presentation, the current understanding of HSRS and the relationship between HSRS and liquid phase will be reviewed and discussed.

Of particular interest in this regard is the formation of non-spherical shapes where there is a need to fabricate both inexpensive, low-precision optics as well as specialized high-precision aspheric components. This work describes the initial feasibility tests of the machining of a new type of glass, lead indium phosphate (LIP), a material which transmits from the visible to 2.8 mu m (for thin samples). Glossy surfaces were produced with a root-mean-square surface roughness of less than 100 nm (with 200 mu m filter). The results indicate that this approach offers the potential for producing high-quality aspheric optical shapes based on the use of LIP glass.

This technique has application to laser cutting and welding, laser ablation, semiconductor mask fabrication, and other tasks. Currently, designs for rectangular and circular flat top profiles have been investigated Experimental results are presented for an element that converts a single mode Gaussian beam into a square, flat top spot. The design is based on a Fourier transform relation between the input and output beam functions and can be implemented as a diffractive or refractive element. The form of the element reduces to a common equation that is scaled for the particular geometry involved. This scale factor contains the product of the widths of the input and output beams, the focal length of the system, and the wavelength. It is a dimensionless quantity that uniquely determines the quality of the target spot, regardless of wavelength or system geometry. A designer can thus start from a desired target quality and lay out the required optical system to achieve that quality, in contrast to an iterative approach.

The exact etiology of pelvi-ureteric junction stenosis is unknown, but there is convincing evidence for a genetic cause: with linkage analysis predicting a hereditary hydronephrosis locus on chromosome 6p. We encountered a patient with a de novo autosomal t(6;19)(p21;q13.1) and attendant bilateral multicystic renal dysplasia (MRD), bilateral PUJO resulting in massive hydronephrosis, and an associated von Mayer-Rokitansky-Kuster disorder. On the basis of the presumption that in this patient the putative hydronephrosis gene might be disrupted by the translocation, we sought to isolate DNA from the breakpoint regions as the initial step in a strategy to identify genes affected by the t(6;19). Using sequential rounds of fluorescence in situ hybridization (FISH) with cosmids selected from a detailed integrated map of the long arm of chromosome 19, we have identified a cosmid clone that spans the breakpoint. The position of the breakpoint was further localized by Southern blot analysis. Using a vectorette PCR approach, rearranged DNA fragments were isolated and: by comparative nucleotide sequence analysis, these were shown to contain ectopic sequences. A cosmid clone containing these ectopic sequences was isolated and shown by CASH (chromosome assignment using somatic cell hybrids) and FISH (fluorescence in situ hybridization) analysis to map to the short arm of chromosome 6 and to span the breakpoint found in the MRD patient. The isolated cosmid clones are useful reagents for analysis of other MRD patients and for the search for genes at or flanking the breakpoints.

GOD-FISH is a strand-specific modification of standard FISH technology which allows the hybridization of single-stranded probes to one, and only one, chromatid of a metaphase chromosome. It can be used to determine the absolute 5'-to-3' direction of DNA target sequences with respect to the short-to-long arm direction of a given chromosome. Since an inversion reverses the orientation of DNA sequences within the inverted region, an inversion becomes detectable as a ''switch'' in probe signal from one chromatid to the other, when compared to a reference probe outside of the inverted region. Pericentric inversions in chromosomes 1, 8, 10, and X, which had previously been identified by chromosome banding, were analyzed by the GOD-FISH technique. The results presented here demonstrate that GOD-FISH can be used for the detection of pericentric inversions and that, in some instances, it provides additional information not obtainable by more conventional methods of cytogenetic analysis. Practical limitations of the GOD-FISH technique are also discussed. C1 UNIV TEXAS,MED BRANCH,DEPT RADIAT THERAPY,GALVESTON,TX 77550. UNIV NEW MEXICO,SCH MED,ALBUQUERQUE,NM 87131.

Its 5' end was found fused to the catalytic domain of the RET protooncogene to generate RET/PTC 1, the most common form of PTC oncogenes in human papillary thyroid carcinoma. This gene has previously been assigned to a very large genomic region, 10q11.22 --> q22.1. Here, we describe the application of a novel hybridization scheme to the physical and genetic mapping of D10S170. First, we selected a homologous large-insert DNA clone from a human P1 library by filter hybridization and confirmed tis authenticity by Southern blot analysis. Triple-color fluorescence in situ hybridization (FISH) experiments mapped this clone to 10q21.2 --> 21.3q. ''Binning'' experiments were performed using a quadruple-color FISH approach aimed toward placing the gene in a genetic interval defined by differentially labeled P1 DNA probes containing known polymorphic markers. We found that multicolor FISH greatly expedites chromosomal mapping. Finally, we applied our FISH approach to determine the extent of deletion involving this locus(D10S170) in a papillary thyroid cancer cell Line, TPC-1.

Strict scoring criteria were developed to minimize recording errors. The protocol used optimized probes for chromosome-specific DNA repeat and single-copy loci and showed a significantly higher efficiency (95 %) than previously published protocols. The other purpose of this study was to differentiate between two signals originating from a single split target or from two targets in close proximity. These criteria were based on the FISH results obtained from the analysis of all or most of the cells from 50 chromosomally normal or mosaic human embryos, 20 aneuploid embryos, and five polyploid embryos donated for research. Subsequently, 183 human embryos underwent PGD of aneuploidy in one of their cells. In 64 embryos that were not transferred back to the uterus, the rest of cells were also analyzed, and the previous results were confirmed in 91 % of these embryos, with 0 % (0/21) of the embryos classified as normal embryos being abnormal and 14% (6/43) of the embryos classified as abnormal being normal. Compared to previous protocols, these criteria minimize the risk of transferring abnormal embryos after PGD analysis. C1 INST REPROD MED & SCI,ST BARNABAS MED CTR,LIVINGSTON,NJ.

A total of 301 cosmids were selected randomly from a flow-sorted human chromosome 10 cosmid library constructed from human x hamster cell line 762-8A and arrayed in microtiter storage dishes. Over 70% (211/301) of the cosmids mapped to unique regions of chromosome 10. About 7% (22/301) produced multiple hybridization signals indicative of chimeric clones or sequences repeated at low copy number. Three cosmids (3/301, or 1%) hybridized to the centromeric regions of chromosome 10 and one or more other human chromosomes. About 19% (59/301) consisted mostly or- entirely of hamster DNA inserts, and about 2% (6/301) appeared to be nonrecombinants.

The specificity of the STSs for human chromosome 2 was first demonstrated by PCR amplification of DNA from genomic human and hamster cells and a human chromosome 2-containing human x hamster hybrid cell line. The STSs were then mapped to chromosome 2 by two different approaches. In the first attempt, 12 of the STSs were shown to PCR amplify YAC clones associated with genetic markers on the chromosome. In the second approach, 27 of the STSs were localized to chromosome bands by FISH using cosmid or PAC clones encoding the STSs. The specific STSs mapped to chromosome 2 by these two approaches tie together the genetic and cytogenetic maps of the chromosome at the two termini. The distribution of these STSs further defines the region of the chromosome present in the two microdissection Libraries.

Critical Dynamics in Microgravity (DYNAMX), a NASA preproject) will study the thermal conductivity in the nonlinear region in Microgravity. Unlike the study of static properties, the thermal conductivity can be derived from the measurement of the spatial temperature profile which is essentially a local measurement of the temperature gradient. We present a method which, in principle, fully removes the apparent impact of gravity from the measurement. The inevitably finite spatial resolution of the probe and temperature resolution of the thermometer, however, make microgravity essential to study the region of interest.

Our results for the binding energies, excitations energies, and effective masses on strong substrates agree well with experimental data of the Amherst group. No substrate bound states are found for substrates as weak as Na. The theory also provides an unambiguous description of atom scattering and sticking. The dependence of the sticking and scattering coefficients on the substrate and the excitations in the film have been calculated.* C1 TEXAS A&M UNIV,DEPT PHYS,COLLEGE STN,TX 77843.

The present work examines the effects of temperature on these transitions. At given temperatures, the spinodal points and phase coexistence boundaries are determined for the transitions. Increasing the temperature tends to decrease the coverage spall of the transition regions, signalling the possible existence of a critical point terminating the two-phase equilibrium.* C1 LOS ALAMOS NATL LAB,DIV THEORET,LOS ALAMOS,NM 87545.

In so doing, the momentum dependence of the electron-phonon matrix elements are neglected, which is equivalent to using a local approximation. The vertex-corrected strong-coupling perturbation theory is performed on the imaginary axis and then an exact analytic continuation is used to produce the density of states on the real axis. Comparison with the experimental data for Pb indicates that effects of vertex corrections may be observable even in low-temperature superconductors. C1 UNIV GUELPH,DEPT PHYS,GUELPH,ON N1G 2W1,CANADA.

In particular, the part of the I - V characteristics due to the UBe13-superconductivity is almost indistinguishable from that of contacts against normal metals. In magnetic fields of a few Tesla the junctions show an anomalous behaviour: the UBe13 critical current increases with the field.

We find that the onset of vortex motion is dominated by filamentary channels of flow. There are multiple patterns of filamentary flow which are stable in a wide range of bias current. As a consequence, there are multiple steps in the differential resistance, each step corresponding to a different pattern of filamentary flow. This results in a strong history dependence of the depinning current and current voltage characteristics. Our results are in agreement with recent experiments on amorphous Mo77Ge23 thin films.

For the former, T-c becomes zero, whereas for the latter, T-c reaches a nonzero constant value beyond a critical concentration of impurities. We report that T-c of single-crystal YBCO becomes less than 12K, our lowest temperature, when 4.1% of the planar oxygens O(2,3) are displaced by 400keV electrons, incident along the c-axis.

At a fixed doping level, the highest T-c is found for flat and square CuO2 planes in the tetragonal structure. T-c is reduced proportionally to the structural distortions of the CuO2 planes in the orthorhombic structure. The local minimum of T-c vs doping is observed for both orthorhombic Ca- and Sr-substituted materials around x similar to 0.12. This minimum may be related to the intrinsic dependence of the electronic density of states at E(F) due to a weakly split singularity of DOS. C1 ARGONNE NATL LAB,DIV MAT SCI,ARGONNE,IL 60439.

The data is consistent with a Lindemann melting criterion, giving a physically reasonable value for c(L) of 0.15 that is in good agreement with previous work. The disappearance of the diffracted intensity coincides with the irreversibility line as measured by an inductance technique. C1 UNIV ST ANDREWS,SCH PHYS,ST ANDREWS KY16 9SS,FIFE,SCOTLAND.

Both materials show very ''low'' lying irreversibility lines (H parallel to c), which follow an exponential law and rise rapidly below T/T-c approximate to 0.5. High critical current densities are found only at low temperatures, e.g. J(c) is about 2.7.10(10) Am-2 at 1 T and 5 K in Tl-2223. A comparison of the condensation energy provided by different types of defects with the thermal energy gives evidence for pinning of individual pancakes by the as-grown defect structure.

We express each site's occupancy in terms of its quasi-electrochemical potential (QECP); currents flow between sites whose QECP's differ. Coupled nonlinear circuit equations result from the steady-state condition and a boundary condition. When site-to-site QECP differences are much smaller than the thermal energy k(B)T, the effect of current flow on occupancies is ignorable, and the equations reduce to those of a resistance network. But this resistor-network model fails: a) at low temperatures, b) with increasing disorder, and c) with increasing emf. We therefore study hopping conduction beyond this approximation. Exactly soluble examples show the importance of current-induced charge redistribution in non-ohmic steady-state flow. C1 TECHNION ISRAEL INST TECHNOL,DEPT PHYS,IL-32000 HAIFA,ISRAEL.

The comparatively low specific resistivity and, therefore, the large electronic mean free path enables point-contact spectroscopy in the Sharvin regime. In the d(2)V/dI(2) characteristics of point-contacts between YbBe13 and normal metals, measured at temperatures between 1.6 and 30K, we find structures due to crystal-field scattering and scattering at spin-fluctuations.

The large energy scale of the crystal electric field splitting of lanthanide orbitals leads to large anisotropies in the magnetic and superconducting properties of many of these compounds. Single crystal transport measurements can help determine the influence of anisotropy on magnetic and superconducting phase boundaries as illustrated by the phase diagram for HoNi2B2C determined by transport and magnetic measurements and delineate the important scattering mechanisms by resistivity and thermopower measurements across the series.* C1 UNIV HYDERABAD,SCH PHYS,HYDERABAD 500046,ANDHRA PRADESH,INDIA.

These needs are driving an intense development of novel low temperature detectors of particles using the small excitation energies available in superconductors (quasiparticles) and insulating crystals (phonons). After reviewing some of the most critical applications, this talk will map the recent progress made with devices based on superconducting transition, tunnel junctions and semiconductor thermistors.

We find that challenges to the existence of market barriers have, for the most part, failed to provide a testable alternative explanation for evidence suggesting that there is a substantial ''efficiency gap'' between consumers' actual investments in energy efficiency and those that appear to be in consumers' best interest. We suggest that differences of opinion about the appropriateness of public policies stem not from disputes about whether market barriers exist, but from different perceptions of the magnitude of the barriers, and the efficacy and (possibly unintended) consequences of policies designed to overcome them. We conclude that there are compelling justifications for future energy-efficiency policies. Nevertheless, in order to succeed, they must be based on a sound understanding of the market imperfections they seek to correct and a realistic assessment of their likely efficacy.

Restructuring proposals at the federal and state levels focus on more competitive market structures for generation and the integration of transmission within those structures. The proposed move to more competitive generation markets will expose utility costs that are above those experienced by alternative suppliers. Debate about these above-market, or transition, costs (e.g., their size, who will pay for them and how) has played a prominent role in restructuring proceedings. This paper presents results from a project to systematically assess strategies to address transition costs exposed by restructuring the electricity industry. C1 OAK RIDGE NATL LAB,OAK RIDGE,TN.

Many of these linkages have been established for the choice or purchase of durables; however, these Linkages have not been established for the decision of when to replace that goad. These types of results are important in the development of policies designed to replace older less efficient appliances with more efficient energy-using stock, as well as in the prediction of stock turnover as the demographic makeup of the population changes. To evaluate the complex effects of socieconomic variables on the length that a household holds an appliance, however much richer relationships between demographic variables, the age of the durable good and probabilities of replacement must be modeled. For this work, a proportional hazard model utilizing a generalized gamma specification was used to fit models of the duration of household energy stocks for both electric and natural gas household appliances utilizing data from the Residential Energy and Consumption Survey (RECS) for 1993.

In L1(2) alloys, a large disparity of edge/screw segments in their relative mobility reduces the efficiency of a Frank-Read type multiplication mechanism. In Fe-40%Al of the B2 structure, a variety of dislocation sources are available for [111] slip, including ones resulting from condensation of thermal vacancies. In NiAl with the relatively high APE energy, [100] dislocations may result from the dislocation decomposition reactions, the prismatic punching out from inclusion particles, and/or steps and coated layers of the surface. Internal interfaces often provide sites for dislocation multiplication, e.g., grain boundaries, sub-boundaries in Ni3Ga, NiAl and Ti3Al, and antiphase domain boundaries in Ti3Al. As for the crack tip as a dislocation source, extended SISFs trailed by super-Shockley partials emanating from the cracks in Ni3Al and Co3Ti are discussed in view of a possible toughening mechanism.

Although the influence of strain rate on the structure / property relationships of pure nickel, iron, and titanium and a variety of their alloys have been extensively studied, the effect of strain rate on the stress-strain response of Ni-, Fe-, and Ti-based aluminides remains poorly understood. Dynamic constitutive behavior is, however, relevant to high speed impact performance of these materials such as during foreign object damage in aerospace applications, high-rate forging, and localized deformation behavior during machining. The influence of strain rate, varied between 0.001 and 10(4) s(-1), and temperatures, between 77 & 800K, on the compressive mechanical behavior of Ni(3)Al, NiAl, Fe(3)Al, Fe-40Al-0.1B, Ti-24A1-11Nb, and Ti-48Al-2Cr-2Nb will be presented. In this paper the influence of strain rate on the anomalous temperature dependency of the flow stresses in these aluminides will be reviewed and compared to one another. The rate sensitivity and work hardening of each aluminide will be discussed as a function of strain rate and temperature and contrasted to each other and to the values typical for their respective disordered base metals.

The temperature dependence of the yield stress was found to depend on the strain rate: At the quasistatic strain rate, 0.001 sec(-1), the yield stress decreases with increasing temperature with a plateau between 200 degrees C and 800 degrees C. At the high strain rate, 2000 sec, the yield stress exhibits a positive temperature dependence at temperatures above 600 degrees C. The strain hardening rate decreases dramatically with temperature in the very low and high temperature regions with a plateau occurring at the intermediate temperatures for both strain rates. As the strain rate increases the strain hardening rate plateaus were seen to extend to higher temperatures. The strain rate sensitivity was found to increase slightly with temperature (but less than 0.1) for strain rates above 0.001 sec(-1). However, at a strain rate of 0.001 sec(-1), there is a dramatic increase in the strain rate sensitivity with increasing temperature. In particular, at temperatures above 1100 degrees C, the rate sensitivity becomes much larger. Microcracks occurring in the grain interiors and at grain boundaries were observed at all strain rates and temperatures. The formation and distribution of microcracks were found to vary depending on the strain rate and temperature of deformation.

B-doped samples, with a nominal composition of Ni - 24 at.% Al and B concentrations of 50, 100 and 500 wppm, were tested in high-purity H-2 gas at pressures ranging from ultrahigh vacuum (UHV, similar to 10(-8) Pa) to 6.7 x 10(3) Pa. Boron-free Ni3Al, with 23.4 at.% Al, was also tested under similar conditions for comparison. The highest elongations to fracture were obtained in UHV: similar to 65, 50, 38 and 40% for the 500, 100, 50 wppm B and B-free alloys, respectively. The use of the ion gage had a dramatic effect on the ductility and fracture mode of the B-free Ni3Al. When using the ion gage, the ductility dropped by a factor of 2 or more compared to tests conducted at the same hydrogen pressure with the gage off while the fracture mode changed from predominantly transgranular (>60%) to predominantly intergranular (>70%). The B-doped material, on the other hand, was not noticeably affected by the ion gage. However, with increasing H-2 pressure beyond similar to 10(-2) Pa the ductility of the B-doped alloys dropped dramatically (the higher the B level the higher the H-2 pressure needed to cause embrittlement). Though the ductilities of the 50 and 100 wppm B alloys at low H-2 pressures are comparable to or higher than those of the B-free Ni3Al alloy, the ductilities of the B-doped alloys tested at H-2 pressures above similar to 1 Pa become significantly lower than those of the B-free alloy. This result indicates that boron-by possibly promoting the dissociation of molecular H-2 into atomic H-actually embrittles Ni3Al in a dry H-2 environment, unlike in moist air where it suppresses environmental embrittlement.

The hardness along [0001] increases from 100 to 300 degrees C followed by a sharp decrease in hardness with temperature; this is accompanied by a large uplift which is observed to surround the indentations. Dislocations produced by the indentations at room temperature and 300 degrees C were analyzed by transmission electron microscopy to find slip by < 10 (1) over bar 0 > dislocations at room temperature with a change in the active slip systems at 300 degrees C. The hardness along the direction 45 degrees from [0001] and [11 (2) over bar 0] sharply decreases with increasing temperature above room temperature. Coarse slip lines surround the indentations corresponding to slip on the basal plane. The details of the dislocations and mechanical properties are discussed.

Alloy FAP-Y was brittle and experienced catastrophic failure by cleavage. K-lc was 23.6 MPa root m and energy release rate, G(lc), was 4.1 kJ/m(2). The introduction of mode III load dramatically increased fracture toughness, yielding G(mc) of 7.9 kJ/m(2). Alloy FA-129 was much tougher than the FAP-Y, giving a K-lc of 44.4 MPa root m and a G(lc) of 14.7 kJ/m(2). In addition, the FA-129 experienced stable crack growth, albeit rapid crack growth. The fracture surface was predominantly cleavage with a small amount dimple fracture. No intergranular fracture was detected. The mixed-mode fracture toughness was 15.1 kJ/m(2), slightly higher than G(lc). The effect of mixed-mode I/III loading on deformation and fracture of both alloys is discussed.

We examined the spatial and temporal patterns of apoptotic cells in relation to those of proteinases during involution of the BALB/c mouse mammary gland. Apoptosis was almost absent during lactation but became evident at day 2 of involution, when p-casein gene expression was still high. Apoptotic cells were then seen at least up to day 8 of involution, when beta-casein gene expression was being extinguished. Expression of sulfated glycoprotein-2 (SGP-2), interleukin-1 beta converting enzyme (ICE) and tissue inhibitor of metalloproteinases-1 was upregulated at day 2, when apoptotic cells were seen initially. Expression of the matrix metalloproteinases gelatinase A and stromelysin-1 and the serine proteinase urokinase-type plasminogen activator, which was low during lactation, was strongly upregulated in parallel starting at day 4 after weaning, coinciding with start of the collapse of the lobulo-alveolar structures and the intensive tissue remodeling in involution. The major sites of mRNA synthesis for these proteinases were fibroblast-like cells in the periductal stroma and stromal cells surrounding the collapsed alveoli, suggesting that the degradative phase of involution is due to a specialized mesenchymal-epithelial interaction. To elucidate the functional role of these proteinases during involution, at the onset of weaning we treated mice systemically with the glucocorticoid hydrocortisone, which is known to inhibit mammary gland involution. Although the initial wave of apoptotic cells appeared in the lumina of the gland, the dramatic regression and tissue remodeling usually evident by day 5 was substantially inhibited by systemic treatment with hydrocortisone. mRNA and protein for gelatinase A, stromelysin-1 and uPA were weakly induced, if at all, in hydrocortisone-treated mice. Furthermore, mRNA for membrane-type matrix metalloproteinase decreased after hydrocortisone treatment and paralleled the almost complete inhibition of activation of latent gelatinase A. Concomitantly, the gland filled with an overabundance of milk. Our data support the hypothesis that there are at least two distinct phases of involution: an initial phase, characterized by induction of the apoptosis-associated genes SGP-2 and ICE and apoptosis of fully differentiated mammary epithelial cells without visible degradation of the extracellular matrix, and a second phase, characterized by extracellular matrix remodeling and altered mesenchymal-epithelial interactions, followed by apoptosis of cells that are losing differentiated functions.

After a finite number of divisions, normal cells irreversibly cease proliferation by a process termed replicative or cellular senescence. Replicative senescence is controlled by multiple, dominant-acting genes about which very little is known. The only genes known to reactivate DNA synthesis in senescent cells are viral oncogenes encoding proteins that bind and inactivate the p53 and retinoblastoma (pRb) tumor suppressor proteins. SV40 T antigen is the best studied of these viral oncoproteins. T[K1] is a T antigen point mutant that selectively is defective in binding pRb and the pRb-related proteins p107 and p130. We show that T[K1] stimulated quiescent human fibroblasts to synthesize DNA nearly as well as wild-type T but was incapable of stimulating senescent cells. We tested several growth regulatory genes that are repressed in senescent cells for ability to restore activity to T[K1]. These included c-fos, c-jun, Id-1, Id-2, E2F-1, and cdc2. Only the helix-loop-helix (HLH) protein, Id-1, restored the ability of T[K1] to reactivate DNA synthesis in senescent cells. This activity of Id-1 was not shared by Id-2, a related protein, and depended on an intact HLH domain. It did not appear that Id-1 interacted directly with pRb or p107. Constitutive Id-1 expression failed to rescue proliferating cells from growth inhibition by pRb, p107, or p130, and failed to interact with pRb in the yeast two hybrid system. Because Id proteins negatively regulate basic-HLH (bHLH) transcription factors, we suggest that senescent cells express one or more bHLH factor that cooperates with pRb, or pRb-related proteins, to suppress proliferation.

These films can provide very low friction coefficients (approximate to 0.04 to 0.15) to sliding SiC and Si3N4 surfaces in air or dry N-2. To understand the mechanisms of friction and wear behavior in relation to the chemical and physical states of the diamond films, we used a variety of analytical techniques (electron diffraction, Raman spectroscopy, X-ray diffraction, scanning electron microscopy, atomic resolution transmission electron microscopy, near-edge X-ray absorption fine structure, and atomic force microscopy) both before and after sliding tests. The results of these studies verified that the films were made of sp(3)-bonded diamond nanocrystals (100-300 Angstrom) and that their surfaces were exceptionally smooth (i.e., 20-40 nm, root mean square). Additionally, pin-on-disk experiments verified that these films provided very low friction coefficients (0.04, in dry N-2) and wear rates, essentially comparable to those of natural diamond. Undoubtedly, such diamond films with smooth surface finish can have significant impact in a wide range of tribological applications.

We have addressed four areas of significant variability in mammograms: flattening the brightness roll-off at the breast tissue boundary, diminishing smooth changes in brightness across the mammogram, reducing unwanted linear structure, and rectifying contrast across mammograms. These steps are likely to be useful to other mammographic image analysis efforts, as well. At present our peak (P-D, FAR) performance point is (0.80, 1.34), on a challenging data set. This is promising but not dramatic. Future work will focus on further improving the selectivity of the edge maps, on better contrast normalization, and on integration with the previously developed methods for microcalcifications and spiculated lesions.

Many researchers are developing algorithms to detect one or more of the discrete lesions: microcalcifications (MCs), spiculated lesions and circumscribed masses. The evaluation and comparison of these algorithms has been difficult, not least because most groups report results based on their own data set. Attempts to compare the quality, difficulty and/or subtlety of data sets are necessarily subjective. Performance metrics for evaluating the algorithms vary and are often subjective due to a lack of objective truth data. In order to address these issues for mammograms featuring MCs, we developed a 12-volume CD library containing digitized mammogram films, associated groundtruth images at full resolution, clinical history information, and radiologists' comments. In practice, the following issues had to be addressed and resolved: selection of representative cases, achieving sufficient quality and resolution from the film digitization process; providing adequate mammogram display and drawing capability on a computer monitor; characterizing the films; selecting text information to include with each image or case; choosing the image data file format; and establishing filename conventions.

When properly deployed, fuzzy matching can significantly enhance the benefits of other, more common approaches to end-user answer retrieval from online reference collections. We compare crude with more sophisticated approximation techniques to explain how astute fuzzy-match software can convert many different near-miss situations (such as those involving faulty prefixes or suffixes, character misplacement, nonstandard word stems, or unanticipated redescription of concepts) into more adequate results. We also suggest practical ways to overcome fuzzy matching's own major drawbacks (namely, problems with search speed, search imprecision, and misinterpretation of search results). The resulting analysis clarifies how to deploy fuzzy matching for maximum effectiveness. We conclude that appropriate fuzzy matching enables more frequent, more flexible search success than do ordinary retrieval-improvement techniques used without it.

A TPMT-positive cosmid clone was then isolated from a human chromosome 6-specific genomic DNA library, and the gene was sublocalized to chromosome band 6p22.3 by fluorescence in situ hybridization, The gene for TPMT was found to be approximately 34 kb in length and consisted of 10 exons and 9 introns. On the basis of the results of 5'-rapid amplification of cDNA ends, transcription initiation occurred at or near a point 89 nucleotides upstream from the translation initiation codon of previously reported TPMT cDNAs, Once the structure of the TPMT gene had been determined, it was possible to perform the PCR with primers complementary to the sequences of introns nanking each exon that encodes enzyme protein with template DNA obtained from subjects with known phenotypes for the TPMT genetic polymorphism. This DNA was isolated from blood samples from 4 unrelated subjects with genetically low TPMT activity and 4 unrelated subjects with high TPMT activity. All subjects with low TPMT activity were homozygous for two point mutations-a G-->A transition at nucleotide 460 in exon 7 and an A-->G transition at nucleotide 719 in exon 10. Both mutations resulted in alterations in amino acid sequence, with Ala-154-->Thr and Tyr-240-->Cys, respectively, All DNA samples isolated from the blood of subjects with high TPMT activity contained ''wild-type'' sequence, Results obtained with these blood samples were confirmed when DNA from four human liver samples with high TPMT activity were found to have wild-type sequence at nucleotides 460 and 719, while three liver samples with intermediate enzyme activity (i.e., samples presumed to be heterozygous for the polymorphism) were heterozygous for the exon 7 and exon 10 mutations present in the blood samples of homozygous low subjects, Transient expression in COS-1 cells of TPMT expression constructs that contained both of the mutations in exons 7 and 10, as well as each independently, demonstrated that each mutation, as well as both together, resulted in decreased expression of TPMT enzymatic activity and immunoreactive protein. Molecular cloning and structural characterization of the TPMT gene as well as elucidation of the molecular basis for a common TPMT genetic polymorphism will help make it possible to develop DNA-based diagnostic tests for the polymorphism and to determine the mechanism by which it results in decreased expression of this important drug-metabolizing enzyme.

In longer DNA fragments, unambiguous reconstitution of DNA sequence is often impeded by the presence of repetitive regions and simple sequence repeats. Here it is demonstrated that SHOM supplemented by measurement of the distance between certain sites (for example, restriction sites or priming sites for PCR) within the analyzed DNA enables sequencing of much longer DNA fragments, containing repeats of different complexity.

Our sample includes the dense clusters M15, 47 Tuc, M30, NGC 6624, M3 and M13. The two main goals of our program are to measure the shape of stellar density profile in clusters (the slope of the density cusp in post core collapse clusters, in particular) and to understand the nature of evolved stellar populations in very dense regions and their variation as a function of radius. The latter includes studies of blue straggler stars and of the central depletion of bright red giants. Our recent WFPC2 study of M15 is described in detail.

The hub actuation is based upon an integral manifold approach in which the system dynamics are approximately linearized to any order of a small parameter epsilon representing stiffness of the robot arms. A polymer film is proposed as a distributed actuator to dampen vibrations due to elasticity in the links. Simulation results are provided which show that the addition of the distributed actuator significantly reduces the displacement and velocity of the first flexible mode in each link compared to hub actuation alone.

Here we present results from two-dimensional (2-D) numerical experiments which incorporate the essential physics and fluid dynamic aspects of the plume-ridge-upper mantle system in order to test the feasibility of this plume-ridge interaction model. Specifically, experiments test the relative importance of physical effects such as strong viscosity variations and thermal and chemical buoyancy forcing in plume-ridge dynamics. Results indicate that both transient and steady-state connections may be established between off-axis plumes and ridges for a range of realistic mantle conditions. The presence of a strongly sloping rheological boundary layer (RBL) is a necessary condition for long-term communication between an off-axis buoyant upwelling and a spreading ridge. The flux of buoyant material to the ridge is also shown to increase with increasing plume-to-mantle density contrast, decreasing plume viscosity and smaller plume-ridge separation distances. Plume-ridge interaction regimes are defined based on the competing effects of plate-driven and buoyancy-driven flow. Thermal erosion of the viscous lithosphere strongly inhibits long-term plume-ridge interaction by enhancing the plates ability to deflect the plume, both head and conduit, away from the ridge axis.

Examples are presented from behavior in an in situ toughened SIC ceramic and in ductile-phase toughened gamma-TiAl intermetallics. In SiC ceramics, marked R-curve toughening is achieved under monotonic loading by grain bridging, which is diminished under cyclic loading through progressive wear at the sliding grain interfaces. As a result, cyclic crack-growth rates are extremely sensitive to K-max and less dependent on Delta K, although at elevated temperatures, behavior is influenced by extrinsic and intrinsic effects associated with deformation and damage of grain-boundary amorphous films. In contrast, fatigue-crack growth in TiNb-reinforced gamma-TiAl is a function of both intrinsic and extrinsic mechanisms, intermediate to behavior in metals and ceramics, such that propagation rates are sensitive to both Delta K and K-max. However, the marked K-dependence of growth rates in these materials necessitates the use of design and life-prediction procedures based on crack initiation, small crack or threshold philosophies.

However, unconsidered dynamics including deterministic oscillations occur if realistic time lags are incorporated. Stability criteria are provided for difference and differential forms of the simplest model. These criteria provide the means of identifying systems expected to exhibit monotonically damped, exponentially damped, or diverging oscillations in toxicant concentration. These unconsidered dynamics can render invalid the assumption of a single equilibrium concentration used in estimation of bioconcentration factors.

Preferred pathways for dispersal (i.e., corridors), as well as dispersal barriers, are difficult to identify when the landscape matrix is composed of a complex mixture of land cover types. We developed an individual-based dispersal model to measure immigration and emigration rates between habitat islands within heterogeneous landscapes. Dispersing individuals of a model organism were simulated as self-avoiding random walkers (SAW) traversing a digital land cover map, with each habitat type assigned a priori a probability that the SAW would enter that habitat type. Each individual began the dispersal process on a random site at the edge of a deciduous forest patch and was allowed to move until it reached a different deciduous forest patch. Visualization of the movement patterns across the landscape was achieved by tabulating the frequency of visitation of successful dispersers to each grid cell on the map. The model was used to estimate the probabilities of disperser transfer between patches by varying the a priori probabilities of movement into each habitat type in order to: (1) estimate the effect of changing landscape heterogeneity on the transfer probabilities, and (2) visualize dispersal corridors and barriers as perceived by model organisms operating by specific movement rules and at specific scales. The results show that 89% of the variability in dispersal success can be accounted for by differences in the size and isolation of forest patches, with closer and larger patches having significantly greater exchange of dispersing organisms. However, changes in the heterogeneity of the landscape matrix could significantly enhance or decrease emigration success from an individual patch, depending on the landscape. Changes in emigration success from an individual patch resulting from changes in matrix heterogeneity were not predictable, and transfer rates between patches were not symmetrical due to differences in the proximity of neighboring patches, and differences in the funneling attributes of certain landscape patterns. Visualizations showed that corridors are often diffuse and difficult to identify from structural features of the landscape. A wide range of organisms with differing movement capabilities can be simulated using the approach presented to increase our understanding of how landscape structure affects organism dispersal.

We examined the elemental compositions of more than 300 black shales and anoxic sediments in order to understand the relation of their chemical variability to the depositional environment. The law calcic shales were found to contain at least four discrete groupings (1-4) whose depositional and early diagenetic redox conditions are suggested by their Fe, Mn, and V concentrations. The calcic shales (72 Paleozoic, 50 Mesozoic, and 42 Cenozoic; >50,000 ppm Al, >4,000 ppm Ca) were examined in terms of the four thermodynamic groups previously defined for the low calcic shales. The Ca/Mn ratios of the calcic black shales fall into four (I-IV) discrete clusters (as opposed to a continuum). This differentiation reflects the stability of Mn minerals in overlying and interstitial waters under varying redox conditions. One cluster (Ca/Mn I) from a period of glaciation (Ordovician-Silurian boundary) has high Mn concentrations and falls on the line: [Mn] = 0.065 [Ca] + 1,280 (ppm) (r = 0.95, n = 7). A second group (Ca/Mn II) from many different localities and ages falls on a line with a lower-slope: [Mn] = 0.038 [Ca] + 187 (ppm) (r = 0.92, n = 21). The third group (Ca/Mn III) falls on the line: [Mn] = 0.011 [Ca] + 152 (ppm) (r = 0.95, n = 19). The greatest number of samples (Ca/Mn IV) fall on the line: [Mn] = 0.0027 [Ca] + 144 (ppm) (r = 0.85, n = 69). In order to establish the depositional environment associated with each of the groups, more modern sediments whose depositional settings are better defined were explored. As a result, the samples from both Ca/Mn I and II can be associated with deposition under oxic water, those from Ca/Mn I remained oxic during early diagenesis. After deposition, Ca/Mn II samples became anoxic, releasing Mn to interstitial waters. The Ca/Mn III and IV group samples were deposited under anoxic waters. In order to establish the thermodynamic environment of the shale component of the calcic shales, it is necessary to extrapolate to the no calcium intercept to determine the Mn content, then apply the rules determined for the low calcic shales. This study demonstrates the wide variety of black shale depositional environments from oxic to methanogenic. Accordingly, black shales can not all be assigned to anode, sulfidic environments without additional chemical analysis and interpretation. The proper environmental assignment should be useful in assessing the economic potential of particular black shale deposits. C1 OFF NAVAL RES,ASIAN OFF,MINATO KU,TOKYO 106,JAPAN.

The spatial distributions of atoms or molecules along direction z are found by ensemble averaging of trajectories followed by averaging with a localized function with a well defined length scale. Two methods were used calculate dependent charge density distributions. In the first, to be called the atom method, the trajectories of charged atoms are averaged. In the second, called the molecule method, a Taylor expansion of charged atom positions relative to molecular centres is performed and the charge density separated into monopole, dipole, quadrupole, octopole, ...components. These distributions are used to calculate the electric potential and in one example to study the progressive loss of structure due to water as the length parameter is scanned through the dimension of a water molecule. This latter result provides a link between simulations with detailed atomic modelling of intermolecular interactions and electric potentials derived from Gouy-Chapman theory. Illustrative examples are chosen from simulations of aqueous solutions of simple alkali halide electrolytes next to charged and uncharged flat metal surfaces. The smallest system has one ion and 157 water molecules, the largest 60 ions and 1576 water molecules. Copyright (C) 1996 Elsevier Science Lrd C1 IBM CORP,ALMADEN RES CTR,DIV RES,SAN JOSE,CA 95120.

Since COads is postulated to be an intermediate in methanol electrooxidation on Pt alloy surfaces, the relative inactivity of Pt3Sn for methanol oxidation appears paradoxical. We present an explanation for this apparent contradiction diction in terms of a unique state of COads on this surface, which is not the same state of CO as occurs on either Pt-Ru or pure Pt surfaces. It is also not a state of COads which is produced by methanol dehydrogenation. The state is unique in the sense that a significant fraction of COads is oxidized at a much lower (<400 mV) potential than the rest of the COads, a phenomenon that does not occur on any other Pt and Pt-alloy surfaces examined in the same way. This CO state is only formed at high coverages by direct adsorption from dissolved CO and is not formed by the dehydrogenation of methanol, since the multiple Pt atom sites needed to dehydrogenate methanol are blocked by COads at low coverage.

The device, called the ribbon channeled plate rotating drum (rprd), consists of two major components, the plate assembly and the drum assembly. The plate assembly contains a machined oi etched plate of individual micro-channels called the ribbon channeled plate. The ribbon channeled plate and other components of the plate assembly combine the advantages of thin gels and capillary arrays in a single unit with few of the disadvantages. The other major component of rprd is the drum assembly, which facilitates direct blotting onto deposition membranes affixed to a large plastic drum. The drum with attached membrane and deposited electrophoretically resolved ladders is easily moved to special units facilitating downstream processing and detection. The drum unit, although versatile, is specifically designed to be used with multiplex sequencing. C1 PACIFIC NW LAB, RICHLAND, WA USA.

Radiant barriers are one method used to reduce this heat transfer. A quasi-steady-state model was developed for predicting attic heat transfer in residences with radiant barrier systems. The model was used to estimate the reduction in cooling load that would occur with a radiant barrier and to identify important construction and environmental parameters that influence this cooling load reduction. The model's output consisted of hourly ceiling heat fluxes inside the house based on hourly weather data inputs. Model results were compared with detailed experimental results from two small test houses. The model predicted typical summer heat flux reductions of between 35 and 43% with different radiant barrier configurations and levels of insulation. These compared to measured heat flux reductions of between 29 and 37% in attics under the same conditions. Sensitivity studies were also conducted to show the effect of uncertainty in several of the important physical attic parameters on the final heat flow predictions of the model.

DOE's In-house Energy Management (IHEM) Program was established in 1975 to implement energy-efficiency improvements at DOE sites across the United States. These diverse sites include power marketing administrations, national laboratories, weapons production facilities, and nuclear reactor facilities, comprising more than 14,000 buildings and 120 million square feet of floor area. Energy expenditures at the 62 eligible sites were about $303 million in 1994, 64 percent of which was for buildings. The IHEM program was funded at $27 million/year in 1995, but is slated by Congress for zero funding in 1996. MEM buildings-related programs include studies, retrofits, new construction, metering, and energy savings performance contracting. Between 1977 and 1994, $47 million was invested in studies and $290 million in 1,100 retrofit projects, with an average payback time of 3 years. This corresponds to an annual savings level of $100 million and a return on investment in excess of 25 percent. DOE has cost-effectively reduced its energy consumption in buildings by 43 percent since 1975, surpassing the fiscal year 2000 requirement of the Energy Policy Act of 1992. This article discusses the difficulties in implementing energy management programs in federal facilities, and how DOE/IHEM is addressing these challenges. This article reviews IHEM's efforts to date, applications-oriented collaborations with DOE R&D programs, institutional and financing issues, and offers some thoughts on future directions.

Further, these kerogens show an acceleratory period under isothermal conditions that is inconsistent with any parallel or nth-order reaction model. Three different models (serial, Bouster, and three-parameter) are tested against isothermal and nonisothermal pyrolysis data for a few samples, with the conclusion that the three-parameter model fits well and is the most stable and reliable. The three-parameter model reduces to a first-order model when the acceleration parameter is zero. The overall activation energy and frequency factor from this model are very close to those of the T-max-shift method recommended earlier. C1 EXXON PROD RES CO,HOUSTON,TX 77252.

We have analyzed Boscan asphaltenes (Venezuela) derived from a marine source rock. The different steps of this molecular modeling are described. First, a 3-D chemical representation of Boscan asphaltene is defined from an analytical data set. Second, the results of molecular dynamic simulations indicate that only a few stable conformations are possible due to the high reticulation of the model of the asphaltene unit obtained.

Data were obtained as a function of particle conversion, with overall mass loss up to 99% on a dry, ash-free basis. Nitrogen release rates are presented relative to both carbon loss and overall mass loss. During devolatilization, fractional nitrogen release from low-rank coals is much slower than fractional mass release and noticeably slower than fractional carbon release. As coal rank increases, fractional nitrogen release rate relative to that of carbon and mass increases, with fractional nitrogen release rates exceeding fractional mass and fractional carbon release rates during devolatilization for high-rank (low-volatile bituminous) coals. At the onset of combustion, nitrogen release rates increase significantly. For all coals investigated, fractional nitrogen loss rates relative to those of mass and carbon pass through a maximum during the earliest stages of oxidation. The mechanism for generating this maximum is postulated to involve nascent thermal rupture of nitrogen-containing compounds and possible preferential oxidation of nitrogen sites. During later stages of oxidation, the fractional loss rate of nitrogen approaches that of carbon for all coals. Changes in the relative release rates of nitrogen compared to those of both overall mass and carbon during all stages of combustion are attributed to a combination of the chemical structure of coals, temperature histories during combustion, and char chemistry.

Over the period 1974-93, real (inflation-adjusted) non-fuel O&M costs escalated from about $23 to about $97 per kilowatt of installed capacity (kW). However, much of the escalation in costs occurred in the 1980s. Over the period 1975-87, real O&M costs escalated at an annual rate of about 11 percent. Since then, the annual growth rate in real O&M costs fell to about 1 percent. The research found that the escalation in O&M costs was primarily due to increased regulatory activity by the Nuclear Regulatory Commission. More important, there is little evidence that the moderation in the growth in O&M costs was regulatory induced, but instead was due to changes in the economic incentives to improve plant performance.

A sample of power purchase contracts for 26 independent power facilities is used as the basis of this assessment. The contracts were executed in various years between 1987-94. We describe qualitative features of the contracts, including dispatchability and allocation of fuel price risk. We standardize the price formulas of the contract sample and conduct a simple statistical analysis. Because of residual price variation and an indication that buyer willingness-to-pay is highly correlated with price, we conclude that bulk power sold by independent power producers is a heterogeneous product, and evidence for competition in market prices is weak.

We use Joskow and Marron's method to analyze twenty utility commercial lighting programs and, like Joskow and Marron, find wide variations in industry reporting practices and savings evaluation methods. We extend the method by systematically accounting for several of the most important sources of variation and comment on how they influence total program costs. Our accounting also allows us to relate remaining program cost variations to the program sizes and the electric supply costs avoided by the programs. We draw qualified, yet affirmative, conclusions regarding the cost effectiveness of the programs.

Many studies have considered the effects of atmospheric uncertainty in global warming, but economic uncertainties have received less analysis. We consider a key component of economic uncertainty: the return on investments in new technologies. Using a mathematical programming model, we show that ignoring uncertainty in technology investment policy may lead to decreases as great as 2 percent in overall expected economic activity in the U.S. with even higher losses in possible future scenarios. These results indicate that both federal and private technology investment policies should be based on models explicitly incorporating uncertainty. C1 ARGONNE NATL LAB,ARGONNE,IL 60439.

Noting that the shifts of fuels within transport has been small, even counting shifts in the fuels used to produce the small amount of electricity used for passenger transport in every country, we find that increased activity and modal shifts also raised CO2 emissions from travel in every country except the USA, We discuss briefly how a change in fuel mix, lower transport energy intensities, or even reduced levels of travel might lead to restraining or reducing CO2 emissions from travel, Recalling that real prices for road fuels have fallen to near their 1973 levels while energy intensities remain level or are falling slowly, we foresee continued increases in travel, particularly in cars and airplanes, pushing emissions even higher. We ask what could restrain CO2 in the future, should stringent restraints become a clear policy goal.

An introduction to the simplex method, an optimization technique of integer programming, is presented. Simplification of complex geometry is required for the formulation of the integer programming problem. A method of 'i-j unfolding' is defined which explains how irregular geometry can be realigned into a simplified form that is suitable for submap interval assignment solutions. Also presented is the processes by which submapping eliminates the decomposition process, producing suitable mapped meshes. The process of submapping involves the creation of 'interpolated virtual edges', user defined 'vertex types' and 'i-j-k space' traversals. The creation of 'interpolated virtual edges' is the method by which submapping automatically subdivides surface geometry. The 'interpolated virtual edge' is formulated according to an interpolation scheme using the node discretization of curves on the surface. User defined 'vertex types' allow direct user control of surface decomposition and interval assignment by modifying 'i-j-k space' traversals. Volume submapping takes the geometry decomposition to a higher level by using 'mapped virtual surfaces' to eliminate decomposition of complex volumes. C1 SANDIA NATL LABS,ALBUQUERQUE,NM 87185.

The source emission rates of the three tracers and ten selected VOCs in ETS were first measured in a room-size environmental chamber for a market-weighted selection of six commercial cigarettes. The ratios of the emission rates of the tracers to the emission rates of the selected VOCs were calculated and compared among the six brands. The utility of the tracers was then evaluated in a field study conducted in five office buildings. Samples for VOCs were collected in designated smoking areas and adjoining non-smoking areas, air change rates were measured, and smoking rates were documented. Concentrations of the three tracers in the smoking areas were calculated using a mass-balance model and compared to their measured concentrations. Based on this comparison, 3-EP was selected as the most suitable tracer for the volatile components of ETS, although pyrrole is also potentially useful. Using 3-EP as the tracer, the contributions of ETS to the measured concentrations of the selected VOCs in the smoking areas were estimated by apportionment. ETS was estimated to contribute 57% to 84% (4.1 to 26 mu g m(-3)) of the formaldehyde concentrations, 44-69% (0.9 to 5.8 mu g m(-3)) of the 2-butanone concentrations, 37 to 58% (1.3 to 8.2 mu g m(-3)) of the benzene concentrations, and 20 to 69% (0.5 to 3.0 mu g m(-3)) of the styrene concentrations. The fractional contributions of ETS to the concentrations of acetone, toluene, ethylbenzene, xylene isomers, and d-limonene were all less than 50%.

Both natural ventilation and basement pressurization reduced average basement radon concentrations from 800 Bq m(-3) to less than 150 Bq m(-3). Natural ventilation reduced radon levels both by dilution and by decreasing basement depressurization and thus the radon entry rate. Basement pressurization reduced radon levels by increasing ventilation and lowering subslab radon levels, but is significantly more difficult to implement than natural ventilation. The operation of the forced air HAC system with a duct that supplied additional outside air to the return side did not reduce indoor radon concentrations. These experiments have clearly demonstrated the relationship between the outdoor-basement pressure differential and the radon entry rate, ventilation rate, and radon levels.

Empirically established uranium uptake factors for humans are linked with the National Council on Radiation Protection and Measurements (NCRP) recommendations on limits for exposure of the public to ionizing radiation. The maximum effective dose equivalent (EDE) to the local population is derived from the USDOE interim drinking water guideline and consideration of the inhalation and ingestion pathways for diet and local soils. The maximum effective dose equivalent estimates calculated for the inhalation and ingestion of uranium from local sources in the environs of the FEMP would be considered negligible under the individual risk level (NIRL) concept developed by the NCRP. However, empirical site data and risk modeling based on these data are necessary to meet USDOE mission objectives at FEMP and other remediation sites. Copyright (C) 1996 Elsevier Science Ltd.

The continuous monitor, located on the roof of the building housing the Environmental Measurements Laboratory, was a two-filter type with a 150 L decay chamber and a fixed outlet filter. The grand mean for the 7 y of outdoor measurements was 4.2 Bq Rn-222 m(-3). It is postulated that low outdoor radon concentrations are due in part to the urban heat dome effect and the relatively small area of unpaved soil, limiting Rn-222 exhalation. Indoor measurements were made in an office in the same building during 1992-1993 using a continuous monitor. The mean concentration based on 1 y of hourly measurements was 6.2 Bq Rn-222 m(-3). The indoor measurements were principally influenced by the central ventilation system which controls the amount of outdoor air in the make-up system and the hours of operation, < 60 per week. The monthly, seasonal, and diurnal variations in radon concentration are presented for both cases. These data support earlier measurements of radon, radon and Rn-220 progeny, and the unattached progeny made in New York City. The continuous outdoor radon data are combined with other measurements to model the radon budget of Manhattan Island. Copyright (C) 1996 Elsevier Science Ltd.

Two years of Rn-222 and Rn-220 data were obtained from a depth of 0.85 m, followed by two years from depths of 0.28, 0.56, 0.85, and 1.28 m. Variations of Rn-220 and Rn-222, before the first winter that sample tubes were installed, were larger than later, indicating that the soil structure, disturbed during installation of the tubes, may have significantly redistributed after the first winter, thus ensuring that the sample was drawn from near the bottom of the tube. At the Chester site, autumn Rn-222 concentrations were found to be up to 10 times higher than winter values, variations larger than predicted assuming diffusion-only transport. Spatial variations up to an order of magnitude were observed over distances of a few meters. The Rn-220 concentrations were typically similar to 2 to 3 times higher during summer than during winter. At the Aberdeen site, Rn-220 and Rn-222 concentrations were about an order of magnitude less than the lowest Chester site values with no statistically significant temporal or spatial variations.

The strategy was to simulate or approximate some of the conditions to which the miners were exposed, then sample the aerosol with modern instrumentation. By combining data from an impactor with data from a diffusion-based sampler, it was possible to cover the particle size range from 0.5 to 5000 nm. The major new finding of these sampling exercises was that, with or without diesel operation, 5 to 30% of the potential alpha energy was bound to particles larger than 1000 nm. These particles formed a well-defined mode (the coarse-particle mode) in the particle size distribution. Current lung models show that tracheobronchial deposition increases with increasing particle size above 1000 nm. Consequently, the existence of coarse particles implies that the lung dose incurred by uranium miners was larger than previously thought. An approximate calculation based on the new data indicates a 40% increase in dose. Copyright (C) 1996 Elsevier Science Ltd. RP US DOE, ENVIRONM MEASUREMENTS LAB, NEW YORK, NY 10014 USA.

This paper shows that, even though an individual short-term winter measurement from the SRRS is a poor predictor of the home's annual-average, living-area radon concentration, an aggregation of such measurements can be used, after adjusting for bias, to characterize the distribution of annual-average, living-area concentrations as determined by the NRRS. Different types of homes require different adjustment equations. This paper presents the adjustment equations and uses them to estimate parameters describing annual-average, living-area concentration distributions. Model approximations and validation are briefly discussed. The methods presented here could be applied to calibrate other radon data sets. Copyright (C) 1996 Elsevier Science Ltd.

The dose rate in air was measured simultaneously using two 25.4 cm diameter, 25 atmosphere, argon filled ionization chambers. An analysis of this data record was performed to assess the degree of temporal variations that result primarily from snow cover, soil moisture, and atmospheric scavenging of radon progeny. The means and extremes for the entire record are provided. Frequency histograms of the record are also provided to examine the variations in the daily average dose rate. The yearly average daily dose rates do not differ by more than 5% from the mean of the entire database. Analysis of the data by season indicates that the winter shows the largest variation and lowest average dose rate. The length of this study provided an opportunity to took for trends matching the 11-y solar cycle; however, the data show no such trend. Copyright (C) 1996 Elsevier Science Ltd.

B6C3F1 mice received single intraperitoneal (i.p.) injections of 82.7, 165.4, or 413.5 mg/kg and round spermatids were sampled at three time intervals representing cells treated in late meiosis, early meiosis, or as spermatogonial stem cells. No increases in the frequencies of SMN were detected for cells treated during meiosis using either SMN-CREST or SMN-FISH methods. After spermatogonial stem-cell treatment, however, elevated frequencies of SMN were detected by both methods. With SMN-FISH, dose trends were observed both in the frequencies of spermatids containing micronuclei and in the frequency of spermatids carrying centromeric label. These findings corroborate the recent report by Alien and colleagues [Alien JW et al.(1994): Mutat. Res. 323:81-88] that CH treatment of spermatogenic stem cells induced SMN. Furthermore, our findings suggest that chromosomal malsegregation or loss may occur in spermatids long after CH treatment of stem cells. Further studies are needed to understand the mechanism of action of the CH effect on stem cells and to determine whether similar effects are induced in human males treated with CH.

The workshop was designed to facilitate interactions among research experts conducting studies on the fundamental biology of chromosomal movement and segregation, on aneuploidy as a human clinical problem, and on toxicological aspects of aneuploidy induction. Overview presentations provided perspectives on aneuploidy as a human clinical problem, the genetics of aneuploidy, and the issues of concern in toxicological testing and regulatory risk assessment. The four choirs introduced the topics for each of their workgroups, setting the stage for subsequent, in-depth discussions on (1) chromosome mover components, (2) altered recombination, (3) parental age effects, and (4) differential chromosome susceptibility. From these discussions, gaps in our research knowledge related to the role of the environment in the etiology of aneuploidy and associated molecular, cellular, and genetic processes involved were identified, and will be used to establish a research agenda for filling those gaps.

The maternal-age effeet, however, shows considerable variability across effected chromosomes. Chromosome-specific variation has been reported in the shapes of the maternal-age-effect curves, including very smell effects for the large chromosomes (groups A and B), linear increases (chromosome 16), and exponential increases (chromosome 21). There is also variation among chromosomes in whether the segregation errors occur predominantly at maternal meiosis I, meiosis II, and/or postfertilization mitotic divisions. There is also limited epidemiological evidence for a paternal-age effect, which was recently supported by the findings of age-related increases in sperm aneuploidy using fluorescence in situ hybridization methods. The paternal-age effect is considerably smeller than the maternal and is more likely to involve meiotic II errors of the sex chromosomes, whereas the maternal-age effect is more likely to arise from meiotic I errors producing autosomal trisomies. These and other differences suggest that constitutional aneuploidy arises by multiple mechanisms that may affect (1) the nature and timing of an initiating lesion affecting the oocyte or sperm; (2) the cellular physiology at the time of the nondisjunction event at meiosis I, II, or postfertilization; and (3) the selection against specific chromosomal aneuploidies during embryonic development. Multidisciplinary research is needed to understand the maternal- and paternal-age effects on aneuploidy, to (1) identify and characterize the genes that control meiosis, recombination, and segregation; (2) identify the microenvironmental factors around the oocyte and male germ cells that are involved in the age effects; (3) develop a laboratory animal model for the age effects; (4) characterize the role of genetics, physiology, and environmental toxicology for the parental-age effects; and (5) identify cohorts of men and women of differing ages who have been exposed to high doses of candidate aneugens and conduct epidemiological investigations of aneuploidies transmitted to their offspring.

(1991): Environ Mol Mutagen 17:4-19] for on in-depth structure-activity study using computational methods. Structural features believed to affect mutagenic potency were tabulated. Molecular orbital energies and other electronic properties of these compounds were calculated using Huckel, semiempirical AM1, and ab initio quantum mechanical methods. Factor interrelationships were studied by multiple linear regression and canonical correlation analyses. Our goal was on improved understanding of the chemical basis of mutagenicity for this class of heterocyclic amines. The major findings were as follows: 1) mutagenic potency is related to the size of the aromatic ring system; 2) potency is enhanced by the presence and location of on N-methyl group; 3) potency is enhanced by addition of ring nitrogen atoms in pyridine, quinoline, and quinoxaline configurations; 4) potency is inversely related to the energy of the LUMO (lowest unoccupied molecular orbital) of the parent amines; 5) potency is directly, though weakly, related to he LUMO energy of the derived nitrenium ions; and 6) the calculated thermodynamic stability of the nitrenium ions (relative to the parent amine) is directly correlated with nitrenium LUMO energy and with the negative charge on the exocyclic nitrogen atom. Although this study raises several intriguing issues relating mutagenicity to chemical properties, further study will be required to determine the plausibility of the nitrenium ion as the ultimate mutagen for binding to DNA.

Uranium particulates had been deposited on the soil through chemical spills and from the operation of an incinerator plant on the site. The major uranium phases were identified using analytical electron microscopy (AEM) combined with electron diffraction as uranyl phosphate (meta-autunite), uranium oxide (uraninite), and uranium metaphosphate [U(PO3)(4)]. The U(PO3)(4) was found predominantly at an incinerator site at fernald. Carbonate leaching in an oxygen environment has removed some of the U(IV) phases; however, U(PO3)(4) has not been removed by any of the chemical remediation technologies tried to date. These observations suggest that an additional physical extraction procedure is needed to remove this phase. Some evidence suggests that the uranium has undergone weathering, resulting in its redistribution within the soil.

These findings suggest that carboxylate groups are important in metal ion adsorption to this biomaterial. Base hydrolysis of the native plant material resulted in a slight increase in metal ion uptake for Cu2+ and Sr2+ and a decrease in uptake for Cd2+. These results are attributed to the hydrolysis of esters native to the plant material, which increases the carboxylate content but also results in conformational changes in the macromolecules that comprise the cell fragments. Both the esterified product and the hydrolyzed material were examined via infrared spectroscopy. A peak occuring at 1735 cm(-1) (attributed to the carbonyl stretch) confirmed the esterification process. The infrared spectra of the hydrolyzed samples indicate further ionization of carboxylate groups or hydrolysis of esters native to D. innoxia.

Evidence exists that upland birds, particularly mourning doves (Zenaida macroura), ingest spent lend shot and that raptors ingest lead shot by consuming wounded game. Mortality, neurological dysfunction, immune suppression, and reproductive impairment are documented effects of exposure to lead in birds. An ecological risk assessment on the impact of lead shot exposure in upland birds was conducted and is presented in the context of the new United States Environmental Protection Agency's Ecological Risk Assessment Paradigm. A considerable amount of spent lead shot is released into the environment each year from shooting and hunting. Doves collected from fields that are cultivated to attract mourning doves for hunting activities show evidence of ingestion of spent lead shot. Because lead can cause both acute and chronic toxicity if ingested by birds, and because there is evidence of widespread deposition of lead shot in terrestrial ecosystems, concern for impacts on upland game birds and raptors seems warranted. Although this ecological risk assessment does not clearly define a significant risk of lead shot exposure to upland game birds, this issue merits continued scrutiny to protect our upland game bird and raptor resources.

Recent advances in chromosome staining using fluorescence in situ hybridization (FISH) facilitate fast and reliable measurement of reciprocal translocations, a kind of DNA damage linked to both prior clastogenic exposure and to risk. In contrast to other biomarkers available, the frequency of reciprocal translocations in individuals exposed to whole-body radiation is stable with time post exposure, has a rather small inter-individual variability, and can be measured accurately at the low levels Here, we discuss results from our studies demonstrating that chromosome painting can be used to reconstruct radiation dose for workers exposed within the dose limits, for individuals exposed a long time ago, and even for those who have been diagnosed with leukemia but not yet undergone radiotherapy or chemotherapy.

Disease in scurfy (sf) mice is mediated by CD4(+) T cells. Based on similarities in scurfy mice and transgenic mice that overexpress specific cytokine genes, we evaluated the expression of cytokines in the lesions of sf mice by Northern blotting, quantitative reverse-transcription polymerase chain reaction (RT-PCR) and by hybridization in situ. Overall, the phenotypic characteristics of scurfy disease correlated well with increased interleukin (IL)-4 (lymphadenopathy), IL-6 (B cell proliferation, hypergammaglobulinemia). IL-7 (dermal inflammatory cell infiltration), and high levels of tumor necrosis factor-alpha (wasting). C1 UNIV TENNESSEE,COLL VET MED,DEPT PATHOL,KNOXVILLE,TN 37996.

Since these stresses are obtainable from a van der Waals-Cahn-Hilliard free energy, the model is, to a certain degree, thermodynamically realistic. Thermal fluctuations are not considered presently for reasons of simplicity. The utility of the model lies in its momentum-conservative representation of surface tension and the simplicity of its numerical implementation resulting from the volumetric modelling of the interfacial dynamics. After validation of the model in two spatial dimensions, two prototypical applications - capillary instability of an initially high-Reynolds-number liquid jet in the gaseous phase and spinodal decomposition in a liquid-gas system - are presented.

Samples of various organs were obtained and counted to calculate the tissue concentration, Radioactivity in the hepatic tumours was very high throughout this study, with a biological half-life of 122.9 h, Radioactivity in the normal liver tissue was also high, but was significantly lower than in the tumour. The biological half-life in the normal liver tissue was 31.7 h, The ratio of tumour concentration to the normal liver tissue concentration was 5.15 at 1 h and rose to 7.7 at 24 h and 10.84 at 48 h. The level of radioactivity in the lung was high at 1 h, and declined rapidly over time. The level of radioactivity in the kidney was moderate throughout the study. The radiation concentrations in muscle, spleen, testis, bone and whole blood were insignificant. We conclude that Re-188-Lipiodol should be considered as a potential radiopharmaceutical for the intra-arterial treatment of hepatic tumours. C1 NATL YANG MING MED COLL,TAIPEI 11221,TAIWAN.

The anomalous properties of EuAg and YbAg, which are due to the divalent nature of Eu and Yb, are quite evident. The use of systematics to estimate the melting points of PmAg, TmAg and LuAg are discussed, and so is the anomalous low melting point of SmAg relative to its neighboring lanthanides. The relative volume ratio technique to estimate the free energy (heat) of formation trend in the RAg compounds may not be too useful since there is considerable scatter in the data. The melting point trend indicates that 4fbonding occurs in the light lanthanide, but not in the heavy lanthanide RAg phases. C1 IOWA STATE UNIV SCI & TECHNOL,DEPT MAT SCI & ENGN,AMES,IA 50011.

The aHF solvent provides for the synthesis of all alkali salts including those of Li+, for which unit cells have been derived: LiAuF4, monoclinic, C2, a(o) = 9.687(2), b(o) = 12.656(2), c(o) = 10.025(2) Angstrom, beta = 92.84(1)degrees, z = 16; LiOsF6, rhombohedral, a(o) = 5.411(1) Angstrom, gamma = 56.31(1)degrees, V = 102.4 Angstrom(3), z = 1; Li(2)MF(6) (M = Ru, Pt, Pd) of tetragonal Li2TiF6 type (z = 2) with: M = Ru, a(o) = 4.657(1), c(o) = 9.096(3) Angstrom, V/z = 98.6 Angstrom(3); M = Pt, a(o) = 4.662(3), c(o) = 9.107(4) Angstrom, V/z = 99.0 Angstrom(3); M = Pd, a(o) = 4.632(8), c(o) = 9.022(8) Angstrom, V/z = 96.8 Angstrom(3). Pd with aHF and F-2, acidified with SbF5, gives green-blue solutions of Pd2+ (solv) from which turquoise Pd(SbF6)(2) is obtained. To aHF solutions of the latter, addition of Li2GeF6 gives blue PdGeF6 {a(o) = 5.44(1) Angstrom, gamma = 55.3(1)degrees}, and addition of alkali fluoride, a lilac precipitate of PdF2. Pd(SbF6)(2) and PdGeF6 are simple paramagnets. C1 UNIV CALIF BERKELEY,LAWRENCE BERKELEY LAB,DIV CHEM SCI,BERKELEY,CA 94720. UNIV CALIF BERKELEY,DEPT CHEM,BERKELEY,CA 94720.

The system is very versatile and has so far been used to study e.g. hydrothermal syntheses of zeolites and aluminophosphates, syntheses of layered phosphates, formation of Sorel cements, dehydration and phase transformations of zeolites, sold state synthesis of lanthanum manganites, ion exchange of zeolites using molten salt, and oxidation/reduction of lanthanum manganites at high temperatures. The sample is contained in quartz capillaries and is heated using a stream of hot air. External pressure can be applied allowing hydrothermal syntheses at temperatures up to 200 degrees C to be performed. Controlled atmosphere is obtained by flowing gas or a mixture of gases through the capillary. RP Norby, P (reprint author), BROOKHAVEN NATL LAB,DEPT CHEM,UPTON,NY 11973, USA.

Many sources of systematic error exist. Therefore collection and analysis of data, as well as the significance of the results require careful consideration. From many experiments at the Brookhaven National Synchrotron Light Source, it is clear that among the usually-quoted R-factors R(I) (or R(B)), R(p) and R(wp), or the goodness-of-fit index S-p [1], only the integrated-intensity R-factor R(I) (or the analogous weighted R-factor R(WL)) is a useful indicator of the quality of the structural model. In agreement with Scott [2], it is found that the goodness-of-fit indicator S-I yields more realistic estimations for the standard deviations than S-p (widely used in Rietveld programs). R(WI) can be used for the application of the standard Hamilton significance tests[3]. All this is illustrated for data collected from SrSO4 at Beamline X7A at the NSLS.

The powder specimens was enclosed in a capillary and submerged in water, then intermittently heated to 584 K in temperature steps of 5 K, Each temperature was maintained for five minutes, while a full powder histogram suitable for Rietveld refinement was accumulated in a CPS120 position sensitive detector, The structure refinements of the 62 resulting powder datasets allow a complete analysis of the structure response to dehydration, The site occupancies of the water molecules in the zeolitic channels at each temperature are related to the anisotropic framework deformations and the changes in the cell volume, The changes in the coordination of the Ca cation and the variations in cation-framework oxygen bond distances are also interpreted on the basis of the cation-zeolitic water interaction. Major releases of water molecules from the structure are found at 349 K (W1 drops to 10% occupancy), at 370 K (60% of W5 is expelled), and in the temperature range 420-480 K (80% of W2 is gradually lost).

Cosmology faces a number of important challenges; foremost among them are determining the quantity and composition of matter in the Universe and developing a detailed and coherent picture of how structure (galaxies, clusters of galaxies, superclusters, voids, great walls, and so on) developed. At present there is a working hypothesis-cold dark matter-which is based upon inflation and which, if correct, would extend the big bang model back to 10(-32) sec and cast important light on the unification of the forces. Many experiments and observations, from CBR anisotropy experiments to Hubble Space Telescope observations to experiments at Fermilab and CERN, are now putting the cold dark matter theory to the test. At present it appears that the theory is viable only if the Hubble constant is smaller than current measurements indicate (around 30 km s(-1) Mpc(-1)), or if the theory is modified slightly, e.g., by the addition of a cosmological constant, a small admixture of hot dark matter (5 eV ''worth of neutrinos''), more relativistic particles, or a tilted spectrum of density perturbations.

These include: (i) adsorbate-adsorbate interactions and diffusion phenomena. We illustrate this with the example of S on Re(0001), where the hopping (diffusion) of S atoms across surface sites was viewed by use of STM. The observed atomic motion was found to be highly correlated, as in a lattice 'liquid', (ii) interaction between different co-adsorbed species, including S and CO, and benzene and CO, that display both repulsive and attractive interactions leading to the segregation or intermixing of the adsorbates; and (iii) adsorbate-substrate interactions that lead to various surface reconstructions, step restructuring and faceting. We give recent results showing CO and S inducing step restructuring and reconstruction of a Pt(111) crystal substrate. Finally, we illustrate the unique capability of STM of operating in virtually any environment by studying the structure of Pt(110) and Pt(111) surfaces in various gas environments (H-2, O-2, CO2 propylene) and at pressures of up to 1.6 atm.

We present the SFG spectra of CO on Pt(lll) as a function of pressure and show evidence for the reversible formation of carbonyl clusters with a CO/Pt ratio of > 1 and for an incommensurate CO layer at high pressures. These species turn over rapidly to produce CO2 during CO oxidation. STM studies show significant reconstruction of Pt(110) in both CO and O-2, while the surface structure of the Pt(lll) crystal face exhibits only minor changes. Platinum nanocluster arrays in the 3-100 nm range have been produced by electron beam lithography. These cluster systems produced on different oxide supports can be used as model catalysts.

We have used neutron reflectometry (NR) with a newly developed shear cell, near-surface small-angle neutron scattering (NSSANS) again in combination with the new shear cell, and regular small-angle neutron scattering (SANS) with a standard Couette shear cell to probe the structures formed in our aqueous surfactant systems and how they react to a flow field, particularly in the near-surface region of a solid/liquid interface. We present data for a 20 x 10(-3) M aqueous solution of 70% cetyltrimethylammonium 3,5-dichlorobenzoate (CTA3,5ClBz) and 30% CTAB. This system forms a very viscoelastic solution containing long thread-like micelles. NR only probes to a depth of ca. 0.5 mu m from the surface in these systems and clearly indicates that adsorbed onto the surface is a surfactant layer which is insensitive to shear. The depth probed by the NSSANS is of the order of 20-30 mu m and is determined by the transmission of the sample, the angle of incidence and the wavelength. In this region, the rods align under shear into a remarkably well ordered hexagonal crystal. The SANS from the Couette cell averages over the entire sample, so that the signal is dominated by scattering from the bulk. While the near-surface hexagonal structure is clearly visible, these data are not consistent with the crystal structure persisting throughout the bulk, leading to the postulate that the bulk structure is a 2D liquid where the rods align with the flow, but do not order in the other two dimensions.

Relative Helmholtz energies of hydrophobic hydration are calculated from these density profiles using two inherently different approaches: Helmholtz energy perturbation and a multiparticle correlation function expansion. Entropic contributions to the hydration Helmholtz energy are also calculated using the multiparticle correlation function expansion for the entropy truncated at the level of pair correlations. We show that the proximity approximations describe water structure around a tetramethylammonium ion in good agreement with neutron diffraction experiments, and provide an accurate description of water structure around simple alkanes and benzene as reflected in their entropies of hydration. Further, we reproduce two important features of hydrophobic interactions: a highly favoured contact minimum and a solvent separated minimum in the PMFs for methane-methane and neopentane-neopentane association in water. Our calculations also show that the more compact conformations of n-butane and n-pentane are favoured in water, as expected based on traditional ideas regarding hydrophobic interactions.

The hydration of molecules of almost arbitrary size (tRNA, antibody-antigen complexes, photosynthetic reaction centre) can be studied in solution and in the crystalline environment. The biomolecular structure obtained from X-ray crystallography, NMR or modelling is required as input information. The structural arrangement of water molecules near a biomolecular surface is represented by the local water density, analogous to the corresponding electron density in an X-ray diffraction experiment. The water-density distribution is approximated in terms of two- and three-particle correlation functions of solute atoms with water using a potentials-of-mean-force expansion.

We review various approaches to fold recognition and break down the process into its main steps: creation of a library of target folds; representation of the folds; alignment of the probe sequence to a target fold using a sequence-to-structure compatibility scoring function; and assessment of significance of compatibility. We emphasize that even though this new field of fold recognition has made rapid progress, technical problems remain to be solved in most of the steps. Standard benchmarks may help identify the problem steps and find solutions to the problems.

Examples are drawn from recent work on titanium aluminide alloys based on both Ti3Al and TiAl. Although the fracture mode in these alloys is often characterized as ''cleavage,'' in reality the fracture surfaces are neither entirely cleavage-like, nor do the ''cleavage'' regions generally correspond to the classical description of cleavage. Implications of such fractographic observations, and of model fracture calculations, are discussed. Needs for further work to clarify fracture processes are also identified.

The effect of the O-2:Ar sputter gas ratio during deposition, on the LSCO film properties was investigated. It was found that the resistivity of the LSCO films deposited at ambient temperature decreases as the O-2:Ar ratio was increased for both the as-deposited and annealed films. In addition, it was found that thin overlayers of LSCO tend to stabilize the underlying Pt/Ti electrode structure during subsequent thermal processing. The LSCO//Pt//Ti composite electrode stack has a low resistivity and provides excellent fatigue performance for PZT capacitors. Furthermore, the LSCO//Pt//Ti electrode sheet resistance does not degrade with annealing temperature and the electrode does not display hillock formation. Possible mechanisms for the stabilization of the Pt//Ti electrode with LSCO overlayers will be discussed. RP Raymond, MV (reprint author), SANDIA NATL LABS,POB 5800,ALBUQUERQUE,NM 87185, USA.

Simply stated, voltage shifts arise from near-interfacial charge trapping in the ferroelectric. We show that the impetus behind voltage shifts in ferroelectric capacitors is the net polarization, with the net polarization being determined by the perovskite and the aligned defect-dipole components. Some common defect-dipoles in the PZT system are lead vacancy-oxygen vacancy complexes. One way to change the net polarization in the ferroelectric is to subject the PZT capacitor to a de bias at elevated temperature; this process is spectroscopically shown to align defect-dipoles along the direction of the applied electric field. The alignment of defect-dipoles can strongly impact several material properties. One such impact is that it can lead to enhanced voltage shifts (imprint). It is proposed that the net polarization determines the spatial location of the asymmetrically trapped charge that are the cause for the voltage shifts. An enhanced polarization at one electrode interface can lead to larger voltage shifts since it lowers the electrostatic potential well for electron trapping, i.e., more electron trapping can occur. Defect-dipole alignment is also shown to increase the UV sensitivity of the ferroelectric. RP Warren, WL (reprint author), SANDIA NATL LABS,POB 5800,ALBUQUERQUE,NM 87185, USA.

The increased integration that can be achieved by replacing surface-mount capacitors should lead to decreased package volume and improved high-speed performance. For this application, chemical solution deposition is an appropriate fabrication technique since it is a low-cost, high-throughput process. The use of relatively thick Pt electrodes (similar to 1 mu m) to minimize series resistance and inductance is a unique aspect to fabricating these devices. In addition, the important electrical properties are discussed, with particular emphasis on lifetime measurements, which suggest that resistance degradation will not be a severe limitation on device performance. Finally, some of the work being done to develop methods of integrating these thin-film capacitors with ICs and MCMs is presented.

Data for the first few ditbction peaks were obtained in the temperature range 27 <= T <= 350 K in order to make a detailed characterization of the F(RL)-F(RH) transition, which takes place for this composition at T(LT)congruent to 323 K. The temperature dependence of the Pb and Zr/Ti(Nb) atomic shifts, and the rotation and distortion of the oxygen octahedra through the transition was derived. The results are compared with published data for PZT with x=0.10, and indicate that (a) the change in Zr/Ti(Nb) shift through T(LH) becomes more pronounced, and (b) the & ortion and tilt of the oxygen octahedra below T(LH) become more important for x=0.035 than for x=0.10. It has been conduded that the increment in the variation of the spontaneous polarization through T(LH) with increasing Zr amount is matnly caused by the increase of the Zr/Ti(Nb) displacement in the low temperature rhombohedral phase.

The hexavalent chromium is determined colorimetrically using its selective reaction with 1,5-diphenylcarbazide in acid. A detection limit of 20 mu g/l in solutions was achieved with a dynamic range up to 5.5 mg/l using an injected sample volume of 25 mu l. Acidic soil extracts prepared by microwave digestion, soil extracts prepared manually using either deionized water or a standard alkaline extraction solution, and soil extracts generated on line were all analyzed using the SI procedure. Cr(VI) concentrations in acidic soil extracts and standards decreased rapidly with time, Total chromium in acidic soil extracts was determined as Cr(VI) in samples first oxidized with acidic Ce(IV). Online soil extraction was performed with the soil placed in an open-ended column attached to the sample line of the SI system. For the type of contaminated soil analyzed, a 5-minute extraction with deionized water produced similar analytical results to those obtained by the standard alkaline extraction procedure, The new SI method for Cr(IV) determination is suitable for field analyses.

Fold assignment methods (also called profile and threading methods) attempt to assign sequences to known protein folds by computing the compatibility of sequence to fold. Results: We have extended profile methods for the detection of protein folds having structural similarity but low sequence similarity to sequence probes. Our extension combines sequence substitution tables with structural properties to form a combined profile. The structural properties used in this study include distances between residues, exposed areas, areas buried by polar atoms, and properties of the original three-dimensional profile method. We compared the performance of these combined profiles with different sequence matrices and with the original three-dimensional profile method. To determine the optimal gap penalties and weights used with these profiles, we employed a genetic algorithm. The performance of these combined profiles was tested by cross validation using independent test and training sets. Conclusions: These studies show that the combined profiles perform better than profiles based on either structural or sequence information alone. (C) Current Biology Ltd.

The addition of mannitol, azide, acetate, or formate at concentrations inversely proportional to the value of the rate constants for the scavenging of OH radicals partially attenuated the supercoiled DNA relaxation. The degrees of protection afforded by the four scavengers in the presence of AMT photoactivated by either 334 nm or 365 nm monochromatic photons were similar, giving an average DRF of about 0.25 in all cases. Given the diverse chemical nature of the scavengers and their wide range of concentrations utilized, these findings are evidence for the involvement of a Type I photosensitization in the induction of DNA single-strand breaks by photoactivated AMT.

The pH dependence indicates that only Me unstable protonated forms of ferrate, H2FeO4 (pK(a) 3.5) and HFeO4- (pK(a) 7.3) are reactive, k(HFeO4- + O-2(-)) = (1.7 +/- 0.2) X 10(7) M(-1)s(-1). The stable ferrate ion, FeO42-, showed no significant reactivity towards either hydrogen peroxide or superoxide anion. The rate constants for the spontaneous dimerization and decomposition of the protonated ferrates, e.g. k(HFeO4- + HFeO4-) approximate to 250 M(-1)s(-1), are orders of magnitudes lower than their corresponding reduction by superoxide indicating an outer-sphere mode of electron transfer for the latter process. In contrast the ferrate(VI) species H3FeO4+ (pK(a) = 1.6 +/- 0.2), H2FeO4, and HFeO4- oxidize hydrogen peroxide, e.g. k(HFeO4- + H2O2) = 170 M(-1)s(-1)), at rates which correspond closely to their dimerization rates suggesting an inner-sphere controlled mechanism.
