On Stationary And Moving Interface Cracks With Frictionless Contact In Anisotropic Bimaterials, Xiaomin Deng Dec 1993

On Stationary And Moving Interface Cracks With Frictionless Contact In Anisotropic Bimaterials, Xiaomin Deng

Faculty Publications

The asymptotic structure of near-tip fields around stationary and steadily growing interface cracks, with frictionless crack surface contact, and in anisotropic bimaterials, is analysed with the method of analytic continuation, and a complete representation of the asymptotic fields is obtained in terms of arbitrary entire functions. It is shown that when the symmetry, if any, and orientation of the anisotropic bimaterial is such that the in-plane and out-of-plane deformations can be separated from each other, the in-plane crack-tip fields will have a non-oscillatory, inverse-squared-root type stress singularity, with angular variations clearly resembling those for a classical mode II problem when …

Neutron Reflection Interferometry: Physical Principles Of Surface Analysis With Phase Information, Vladimir Gudkov, G. I. Opat, A. G. Klein Dec 1993

Neutron Reflection Interferometry: Physical Principles Of Surface Analysis With Phase Information, Vladimir Gudkov, G. I. Opat, A. G. Klein

Faculty Publications

It is shown that the analysis of surface layers by neutron reflection interferometry is considerably enhanced by performing the reflectometry with phase information. We discuss two methods of providing such information. One method involves physically adding an extra reference layer, whose amplitude and phase are known theoretically. The other uses the Lloyd's mirror configuration, in which a directly propagating ray that interferes with the reflected ray supplies the phase information. The methods have much in common with holography.

Driven Diffusion Of Particles, First-Passage Front, And Interface Growth, R. Bidaux, Ras B. Pandey Oct 1993

Driven Diffusion Of Particles, First-Passage Front, And Interface Growth, R. Bidaux, Ras B. Pandey

Faculty Publications

We study a computer-simulation model for driven particles on a discrete lattice where a fraction p of the lattice sites is randomly occupied by frozen impurities (barriers), and an imposed bias governs the particles’ hopping through the lattice. These particles (the carriers) are initially released from a source of wetting fluid from one end of the lattice in order to wet and the dry lattice on their trails. We study the transport of particles, frontier of their trail, and the growth of the interface between the wet and dry regions as a function of the biased field and the number …

Ordering Processes In Porous-Media, J.C. Lee Jun 1993

Ordering Processes In Porous-Media, J.C. Lee

Faculty Publications

The ordering processes in a binary liquid mixture confined in a Vycor type of pore and at temperatures near the transition temperature of the pure system Tc are studied using a kinetic Ising model and the method of Monte Carlo simulations. The results for dynamics show quite clear signatures of the pore width but no notable difference between T > Tc and T < Tc. In the results for statics, the small angle part of the structure factor increases rapidly as T approaches Tc in the one-phase region. This suggests the onset of ordering but the fluctuation of …

An Exploration Of High-Risk Leisure Consumption Through Skydiving, Richard L. Celsi, Randall L. Rose, Thomas W. Leigh Jun 1993

An Exploration Of High-Risk Leisure Consumption Through Skydiving, Richard L. Celsi, Randall L. Rose, Thomas W. Leigh

Faculty Publications

A sociocultural approach is used to explore voluntary high-risk consumption Specifically, we examine the dynamics of individuals' motives, risk perceptions, and benefit/cost outcomes of participation in increasingly popular high-risk leisure activities such as skydiving, climbing, and BASE jumping (parachuting from fixed objects). An ethnography of a skydiving subculture provides the primary empirical data. We propose an extended dramatic model that explains both macroenvironmental and inter- and intrapersonal influences and motives for high-risk consumption. Key findings indicate (1) an evolution of motives that explains initial and continuing participation in high-risk activities and (2) a coinciding evolution of risk acculturation that leads …

Effects Of Crosstalk On Fidelity In Page-Oriented Volume Holographic Optical Data Storage, Gregory P. Nordin, P. Asthana May 1993

Effects Of Crosstalk On Fidelity In Page-Oriented Volume Holographic Optical Data Storage, Gregory P. Nordin, P. Asthana

Faculty Publications

Using numerical simulation, we quantitatively examine the effects of cross talk on the recall fidelity of stored binary data in a page-oriented volume holographic memory system. We discuss the trade-off between the signal-to-noise ratio of the reconstructed bits and the optical throughput of the system (i.e., the fraction of the incident beam that is diffracted to the detector plane). We show that significant gains in the signal-to-noise ratio can be achieved with modest decreases in optical throughput in the region where the highest throughput occurs. The magnitude of this trade-off is influenced by both beam degeneracy and coherent recording cross …

Evidence Of A Nondiffusive Transport In A Monodisperse Screened Coulomb System By A Molecular-Dynamics Simulation, Michael Wild, Ras B. Pandey May 1993

Evidence Of A Nondiffusive Transport In A Monodisperse Screened Coulomb System By A Molecular-Dynamics Simulation, Michael Wild, Ras B. Pandey

Faculty Publications

A molecular-dynamics simulation is carried out for particles (tracers) interacting with a screened Coulomb potential in three dimensions. A phase transition is observed from a liquid to an fcc solid on reducing the temperature at a fixed density, consistent with previous studies. In the liquid phase, the variation of the rms displacement Rtr of the charged particles with time seems to depend on the density and the temperature. In the short-time regime, the effective exponent k for the subdiffusive power-law behavior, i.e., Rtr∼tk, decreases on increasing the density and lowering the temperature. A crossover from …

Judicial Reporting Under The Civil Justice Reform Act: Look, Mom, No Cases!, R. Lawrence Dessem Apr 1993

Judicial Reporting Under The Civil Justice Reform Act: Look, Mom, No Cases!, R. Lawrence Dessem

Faculty Publications

This article addresses the new reporting provision of the Civil Justice Reform Act. Part II analyzes the reporting requirement and the requirement's legislative history. Part III describes the implementation of the requirement by the federal judiciary, while Part IV discusses the initial reports filed pursuant to the provision and the media coverage of those reports. Part V next analyzes the wisdom of the reporting requirement, concluding that, on balance, the requirement may be helpful in furthering public accountability of an independent federal judiciary. Part VI then considers what the data now publicly reported under the Civil Justice Reform Act does, …

Analysis Of Weighted Fan-Out/Fan-In Volume Holographic Interconnections, Gregory P. Nordin, P. Asthana, B. Keith Jenkins, A. R. Tanguay Mar 1993

Analysis Of Weighted Fan-Out/Fan-In Volume Holographic Interconnections, Gregory P. Nordin, P. Asthana, B. Keith Jenkins, A. R. Tanguay

Faculty Publications

The feasibility of employing volume holographic techniques for the implementation of highly multiplexed weighted fan-out/fan-in interconnections is analyzed on the basis of interconnection fidelity, optical throughput, and complexity of recording schedule or implementation hardware. These feasibility criteria were quantitatively evaluated using the optical beam propagation method to numerically simulate the diffraction characteristics of volume holographic interconnections recorded in a linear holographic material. We find that conventional interconnection architectures (that are based on a single coherent optical source) exhibit a direct trade-off between interconnection fidelity and optical throughput on the one hand, and recording schedule or hardware complexity on the other. …

The Differing Treatment Of Efficiency And Competition In Antitrust And Tortious Interference Law, Gary Myers Jan 1993

The Differing Treatment Of Efficiency And Competition In Antitrust And Tortious Interference Law, Gary Myers

Faculty Publications

During the last twenty years, there has been a revolution in antitrust law. As a result of extensive scholarly and judicial analysis, a new learning has developed concerning the content, role, and effect of antitrust doctrines. This trend has focused primarily on the primacy of consumer welfare and economic efficiency. Most commentators now assume that these two interrelated goals are the principal, if not exclusive, concerns of antitrust law. The United States Supreme Court has responded to these new approaches by modifying or altering antitrust law in a long series of cases. Similarly, the new learning has affected the focus …

Methane Consumption In Temperate And Subarctic Forest Soils: Rates, Vertical Zonation, And Responses To Water And Nitrogen, A. P.S. Adamsen, G. M. King Jan 1993

Methane Consumption In Temperate And Subarctic Forest Soils: Rates, Vertical Zonation, And Responses To Water And Nitrogen, A. P.S. Adamsen, G. M. King

Faculty Publications

Rates of methane consumption were measured in subarctic coniferous and temperate mixed-hardwood forest soils, using static chambers and intact soil cores. Rates at both sites were generally between 1 and 3 mg of CH4 m-2 day-1 and decreased with increasing soil water contents above 20%. Addition of ammonium (1 μmol g of soil-1) strongly inhibited methane oxidation in the subarctic soils; a lesser inhibition was observed for temperate forest samples. The response to nitrogen additions occurred within a few hours and was probably due to physiological changes in the active methane-consuming populations. Methane consumption in soils from both sites was …

Application Of A Tetrazolium Salt With A Water-Soluble Formazan As An Indicator Of Viability In Respiring Bacteria, P. Roslev, G. M. King Jan 1993

Application Of A Tetrazolium Salt With A Water-Soluble Formazan As An Indicator Of Viability In Respiring Bacteria, P. Roslev, G. M. King

Faculty Publications

The tetrazolium salt sodium 3'-{1-[(phenylamino)-carbonyl]-3,4- tetrazolium}-bis (4-methoxy-6-nitro)benzene-sulfonic acid hydrate (XTT) was examined for use as a colorimetric indicator of viability in respiring bacteria. XTT was reduced to an orange, water-soluble formazan product by Methylosinus trichosporium OB3b, Pseudomonas putida, Escherichia coli, and Bacillus subtilis. Formazan production was proportional to live cell biomass, and XTT was reduced by all cultures in the absence of added electron-coupling agents. XTT reduction by M. trichosporium OB3b was linear over several hours and was stimulated by the presence of an exogenous substrate (methanol). Addition of cyanide to cultures incubated under oxic conditions gave an initial 10-fold …

Glycine And Alanine Supplementation Of Culture Medium Enhances Development Of In Vitro Matured And Fertilized Cattle Embryos, K. Moore, K. R. Bondioli Jan 1993

Glycine And Alanine Supplementation Of Culture Medium Enhances Development Of In Vitro Matured And Fertilized Cattle Embryos, K. Moore, K. R. Bondioli

Faculty Publications

One-cell cattle embryos were prepared by in vitro oocyte maturation and fertilization (IVM/IVF) and cultured with or without oviductal cells. Embryos were evaluated after 7 days in culture to determine the percentage developing from the 1-cell stage to the morula or blastocyst stage. The combination of glycine (2 mM) and alanine (1 mM) with oviductal cells (experiment 1) improved embryo development over that in control culture (29 vs. 13%; p < 0.05). An optimum response was obtained with 10 mM glycine and 1 mM alanine in coculture (experiments 2 and 3). In experiment 4, the effects of glycine (0 or 10 mM), alanine (0 or 1 mM), and the presence or absence of oviductal cells were tested. In the absence of oviductal cells, the addition of glycine, alanine, or glycine and alanine combined improved embryonic development over that in control medium (45, 33, 42 vs. 24%, p < 0.001, p < 0.05, p < 0.001, respectively). However, the effect of the combination of glycine and alanine was not different from that of glycine alone when oviductal cells were absent (42 vs. 45%, p > 0.10). In the presence of oviductal cells, glycine or the combination of glycine and alanine improved embryonic development over that in the control medium with cells (47, 55 vs. 37%, …
