Extracting The Grain Boundary Character/Free Energy Relationship From The Microstructure: Pure <100> And <111> Tilt Boundaries, Brent L. Adams, S. Costiner, D. Kinderlehrer, W. W. Mullins, Shlomo Ta'asan

Faculty Publications

This work was supported primarily by the MRSEC Program of the National Science Foundation under Award Number DMR-9632556. Analysis is described to extract the excess free energy of grain boundaries from the mesotexture of well-equilibrated polycrystalline samples. The approach is based upon the force and torque balances at triple junctions described in the classical work of Herring. The main advantage of the approach is that the free energy function is obtained over the full fundamental zone of grain boundary types. For the purposes of exposition, the method is described for specified two-parameter hypersurfaces in the fundamental zone for cubic polycrystals …

The Effect Of Home Environment On Adolescent Substance Use And Depressive Symptoms, S. Susan Su, John P. Hoffmann, Dean R. Gerstein, Robert A. Johnson

Faculty Publications

We used data from the screening phase and first two waves of a panel study to compare the home environments of families with a substance-abusing parent, families with a depressed parent, and families in a comparison group. We diagnosed substance use disorder and affective disorder by administering the Structural Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders (third edition, revised) to each participating parent. The data suggest that families in which parents display a substance use disorder are very similar to those in which parents suffer from affective disorder, in terms of negative life events and lower …

The Puzzling Purposes Of Statutes Of Limitation, Tyler T. Ochoa, Andrew Wistrich

Faculty Publications

One hundred years ago, Oliver Wendell Holmes, Jr. asked, "What is the justification for depriving a man of his rights, a pure evil as far as it goes, in consequence of the lapse of time?" A century later, we are still searching for a satisfactory answer to that question. The purpose of this Article is to press that inquiry further.

The law of limitation of actions is the set of legislatively and judicially created legal rules-including the classification of claims, the duration of limitation periods, the applicable principles of accrual and tolling, and the like-that determine whether a claim is …

Stories From The Gender Garden: Transsexuals And Anti-Discrimination Law, Patricia A. Cain

Faculty Publications

Federal antidiscrimination law (Title VII) and most state antidiscrimination laws do not apply to discrimination against transsexual persons. The standard legal analysis is that such discrimination is not discrimination on the basis of "sex." This article employs a narrative method in order to raise the reader's consciousness about the lives of transsexual and transgendered persons. Specifically, the article focuses on the stories of female-to-male transsexuals (FTMs) and other females who have embraced male attributes (e.g., butch lesbians). The very existence of many FTMs who are part-male and part-female challenges the bipolar nature of our current sex jurisprudence which assumes that …

The Validity Of The Qualitative Measures Of Teaching Performance Scale As A Measure Of Teacher Effectiveness, J. Len Gusthart, Ivan M. Kelly, Judith E. Rink

Faculty Publications

The purpose of this study was to determine the relationship between the Qualitative Measures of Teaching Performance Scale (QMTPS; Rink & Werner, 1989) and teacher effectiveness in producing student achievement. The QMTPS focuses primarily on variables related to teacher clarity and task presentation. Nine middle school generalist (classroom) teachers were asked to teach volleyball forearm pass and serve over eight lessons as part of their normal curriculum. Students were pre- and post tested on the serve and forearm pass using the American Alliance for Health, Physical Education and Recreation (1969) volleyball tests. All lessons were videotaped and were coded using …

Ellipsometric And Raman Spectroscopic Study Of Thermally Formed Films On Titanium, E. Hristova, Lj. Arsov, Branko N. Popov, Ralph E. White

Faculty Publications

Thermal films on titanium surfaces were formed by heating titanium samples in air at atmospheric pressure. The optical constants, thickness, and structure of the formed films at various temperatures and times of heating were investigated by ellipsometry and Raman spectroscopy. The complex index of refraction and the thickness of generated films were determined by comparing the experimental loci and obtained by ellipsometric measurements with theoretical computed vs. curves. It was found that the thickness in homogeneity and porosity of formed films increase with increasing temperature and the duration of the thermal treatment. Beyond a certain critical temperature, the appearance of …

The Effects Of Organic Compounds On Inhibition Of Hydrogen Permeation Through A Mild Steel Membrane, H. A. Duarte, D. M. See, Branko N. Popov, Ralph E. White

Faculty Publications

The effectiveness of 5-(4-pyridyl)-2,7-nonadiene, and 1 phenyl-2-propyn-ol (PP) on inhibition of the hydrogen evolution reaction on a 1010 steel membrane and on the degree of hydrogen ingress into the membrane was determined. Hydrogen evolution rates and permeation currents were monitored as a function of time at different applied potentials. In the presence of 0.5 g/liter PP in the electrolyte, the hydrogen discharge and permeation current density were inhibited by 98 and95%, respectively.

Discovery In International Legal Developments Year In Review: 1996, Christopher J. Borgen

Faculty Publications

American procedure regarding international discovery stems from 28 U.S.C. §§ 1781-83, and Federal Rule of Civil Procedure (FRCP or Rule) 28(b). Broadly speaking, these rules are concerned with the mechanics of assessing requests for discovery in the United States to assist a proceeding in a foreign country and attempts by one or more parties before a U.S. court to obtain evidence located in another country. This article serves as a brief review of developments during the year.

Electrowinning Of Nonnoble Metals With Simultaneous Hydrogen Evolution At Flow-Through Porous Electrodes Iii. Time Effects, Mahmoud M. Saleh, John W Weidner, Bahgat E. El-Anadouli, Badr G. Ateya

Faculty Publications

The electrowinning of zinc from a recirculating alkaline zincate solution at a flow-through porous electrode was investigated. Experimental results were obtained to test the predictions of a mathematical model. The effects of electrolyte flow rate, cell current, and electrode thickness on the concentration-time relations and coulombic efficiency-time relations were studied. The experimental results show that the highest recovery rate was obtained at both high flow rates and cell currents. There is, however, a practical limit for increasing both the cell current and the electrolyte flow rate. Reasonable agreement between the model predictions and experimental results was obtained. A case study …

An Electrochemical Route For Making Porous Nickel Oxide Electrochemical Capacitors, Venkat Srinivasan, John W. Weidner

Faculty Publications

Porous nickel oxide films were prepared by electrochemically precipitating nickel hydroxide and heating the hydroxide in air at 300°C. The resulting nickel oxide films behave as an electrochemical capacitor with a specific capacitance of 59 F/g electrode material. These nickel oxide films maintain high utilization at high rates of discharge (i.e., high power density) and have excellent cycle life. Porous cobalt oxide films were also synthesized. Although the specific capacitances of these films are approximately one-fifth that of the nickel oxide films, the results demonstrate the versatility of fabricating a wide range of porous metal oxide films using …

Molecular-Level Modeling Of The Viscoelasticity Of Crosslinked Polymers: Effect Of Time And Temperature, Philip P. Simon, Harry J. Ploehn

Faculty Publications

We present a new molecular-level picture of chain dynamics for describing the viscoelasticity of crosslinked polymers. The associated mathematical model consists of a time-dependent momentum balance on a representative polymer segment in the crosslinked network, plus phenomenological expressions for forces acting on the segments. These include a cohesive force that accounts for intermolecular attraction, an entropic force describing the thermodynamics governing chain conformations, and a frictional force that captures the temperature dependence of relative chain motion. We treat the case of oscillatory uniaxial deformation. Solution of the model equations in the frequency domain yields the dynamic moduli as functions of …

Lithium Bonding Interaction In H2Cy⋯Lif (Y=O,S) Complexes: A Theoretical Probe, Salai Cheettu Ammal, P. Venuvanalingam, S. Pal

Faculty Publications

Ab initio calculations at 6-31++G(d,p) level have been done on H2CY⋯LiF (Y=O,S) complexes choosing ten possible orientations in each complex. The effect of correlation on complex binding energies has been studied via single point MP2 (full) calculations done on 6-31++G(d,p) geometry. Binding energies have been corrected for basis set superposition error. Frequency calculations confirm that H2CO⋯LiF and H2CS⋯LiF complexes have three and two stable forms, respectively. The most stable form in each complex has been found to have a strong lithium bonding interaction and a secondary hydrogen bondinginteraction. NBO analysis has revealed that in this form oxygen donates nσ lone …

Pitfalls In Tests For Changes In Correlations, Brian H. Boyer, Michael S. Gibson, Mico Loretan

Faculty Publications

Correlations are crucial for pricing and hedging derivatives whose payoff depends on more than one asset. Typically, correlations computed separately for ordinary and stressful market conditions differ considerably, a pattern widely termed "correlation breakdown." As a result, risk managers worry that their hedges will be useless when they are most needed, namely during "stressful" market situations. We show that such worries may not be justified since "correlation breakdowns" can easily be generated by data whose distribution is stationary and, in particular, whose correlation coefficient is constant. We make this point analytically, by way of several numerical examples, and via an …
