Infrared Absorption Study Of Potassium-Boro-Vanadate-Iron Glasses, Dinesh K. Kanchan, Harshvadan R. Panchal

Turkish Journal of Physics

The IR studies have been made in the K_2O-B_2O_3-V_2O_5-Fe_2O_3 glass system. The increase in intensity and shifting of vibrational bands towards lower wave number at 1400-1350 cm^{-1}, 1200 cm^{-1} and 100-940 cm^{-1} in IR spectra have been ascribed to the formation of BO_3 to BO_4 and VO_5 to VO_4 tetrahedra along with the formation of non-bridging oxygens attached to boron and vanadium. In heat-treated glass samples, many new vibrational bands have been observed which were however, absent in the untreated samples. The preservation of the 1020 cm^{-1} band assigned to V=O bond suggests that K_2O shows the preference for borate …

Domain Structures Of Epitaxial Perovskite Ferroelectric Films: Part Ii. Applications, S. Pamir Alpay, Alexander L. Roytburd

Turkish Journal of Physics

The use of domain stability maps for epitaxial perovskite ferroelectric films is illustrated with some examples. The equilibrium domain structure and domain fractions as a function of temperature are predicted for PbTiO_3(001) films grown epitaxially on three different substrates: MgO(001), KTaO_3(001), and SrTiO_3(001). Misfit dislocation formation at the growth temperature is found to have a profound effect on both the domain selection and relative domain populations. Theoretical predictions are compared with available experimental data.

Compositional Dependence Of Properties Of Rf-Sputtered Bi-Sr-Ca-Cu-O Thin Films, Ayhan Güldeste

Turkish Journal of Physics

Compositional dependence of superconducting transition temperature (T_c) of Bi_2Sr_{3-x}Ca_xCu_2O_{8+x} thin films grown by rf sputtering on single crystal MgO substrates has been investigated. Films have been assessed by considering their initial composition in terms of (Ca+Sr)/Bi ratio with their atomic concentration normalized to Cu:2. It was found that T_{c-zero} of around 80K is achievable for (Ca+Sr)/Bi ratio between 1.4 and 1.65, while T_{c-onset} remains above 90K. Quenching from high temperature increased T_{c-zero,} but it may result in a deterioration in resistivity due to micro cracks induced by the thermal stress.

Electronic Structure Of Optimized Si_{M}H_{N} Clusters: Mindo3 And Am1 Calculations, Şakir Erkoç, Lemi Türker

We have investigated the electronic structure of optimized hydrogenated silicon microclusters. Si_{m}H_{n} (m=2,3,5,6; n = 4,6) have been investigated. The calculations were performed using both MINDO3 and AM1 semiempirical molecular orbital methods.

A Mean Field Model With Two Order Parameters For Three-Phase Coexistence Near The Tricritical Point, S. Sali̇hoğlu

Turkish Journal of Physics

This study gives a mean field model with two order parameters for three-phase coexistence near the multicritical point. The critical exponents calculated from our model are the tricritical exponents for the order parameters, susceptibility and the specific heat. Hence, our mean field model describes adequately the tricritical behaviour of a system in the region of three-phase coexistence.

Numerical Calculation Of Energy Loss Rate For E^+ + E^- \Rightarrow \Nu + \Bar{\Nu} Process, A. Aydemir

Turkish Journal of Physics

The energy loss rate for pair annihilation is calculated numerically in V-A (Fermi theory) and Weinberg-Salam (Standard theory) theories, taking into account also the variation of density at various temperatures using the results obtained in closed form by Chiu, and Schinder, et al. The calculations made by Chiu, and Salpeter, et al., are seen to be parallel to each other. Dicus has calculated energy loss rate for this process only for a few limiting cases since the integrals can not be taken analytically for all \lambda and \nu. The graph drawn for the values we obtained is compared with the …

The Effect Of Spatially Dependent Screening On The Donor Ionization Energy In A Quantum Wire, B.N. Onwuagba

Turkish Journal of Physics

The effect of the spatially dependent screening on the ionization energy of a shallow donor in a 1D quantum well wire made of Ga_{1-x}Al_x/GaAs superlattice is presented. A variational approach is used to obtain ionization energy of the on-centre impurity at the origin of the well and the results obtained are compared with the existing values.

^{19}F Nmr Study Of Flux-Line Dynamics In Fluorinated Yba_2cu_4o_8, Figen Tabak, Mavrizio Corti̇

Turkish Journal of Physics

Measurements of the ^{19}F NMR linewidth \Delta \nu and spin-lattice relaxation rate 1/T_1 have been performed in an oriented powder sample of fluorinated YBa_2Cu_4O_8 at temperatures 4 < T < 300 K and static magnetic fields 0.3 < H_0 < 9.4 T for Hollc. Thermal motion of flux lines was evidenced from the effect on NMR linewidth while 1/T_1 showed the effects due to interaction with Fermi liquid.

Jam For Justice Holmes: Reassessing The Significance Of Mahon, William Michael Treanor

Georgetown Law Faculty Publications and Other Works

When courts and commentators discuss Pennsylvania Coal Co. v. Mahon, they use the same word with remarkable regularity: famous. Mahon has achieved this fame in part because it was the occasion for conflict between judicial giants, and because the result seems ironic. Justice Oliver Wendell Holmes, Jr.--the great Lochner dissenter and a jurist generally considered a champion of judicial deference to legislatures in the sphere of economic decision-making--wrote the opinion striking down a Pennsylvania statute barring coal mining that could cause the surface to cave-in. Sharply dissenting from Holmes's opinion was his consistent ally on the Court, Justice Louis …

Sexual Dis-Orientation: Transgendered People And Same-Sex Marriage, Mary I. Coombs

Articles

In this Article, Professor Coombs argues that the debate about same-sex marriage has wrongfully ignored transgendered people and their relationships. She provides an overview of arguments made by opponents of same-sex marriage, such as tradition, procreation, child-rearing, and family values. She then examines cases involving transsexual marriages and uses this analysis to deconstruct the same-sex marriage debate. Professor Coombs argues that an honest consideration of transgendered people and their relationships forces a re-evaluation of arguments against same-sex marriage and disrupts the gendered patriarchy on which traditional marriage rests. Marriage should be seen as a relationship between two people, regardless of …

A Complex-Systems Perspective On The “Computation Vs. Dynamics” Debate In Cognitive Science, Melanie Mitchell

Computer Science Faculty Publications and Presentations

I review the purported opposition between computational and dynamical approaches in cognitive science. I argue that both computational and dynamical notions will be necessary for a full explanatory account of cognition, and give a perspective on how recent research in complex systems can lead to a much needed rapprochement between computational and dynamical styles of explanation.

Article 2b As Legal Software For Electronic Contracting-Operating System Or Trojan Horse?, A. Michael Froomkin

Articles

The proposed draft of Article 2B of the Uniform Commercial Code can be thought of as akin to a complex computer software suite which seeks to dominate a market by offering all things to all people. The author suggests, however, that Article 2B's electronic contracting rules interoperate poorly with existing digital signature laws, and with some forms of electronic commerce. The author also questions whether Article 2B is the proper means to enact controversial rules that ordinarily would make consumers liable for fraudulent uses of their digital signatures by third parties. After considering Article 2B's potential interaction with existing digital …

On Dorfman’S ‘Death And The Maiden’, David Luban

Georgetown Law Faculty Publications and Other Works

This Essay was originally prepared for a panel on transitional justice entitled "Justice, Amnesty, and Truth-Telling: Options for Societies in Transition," American Philosophical Association, Eastern Division, convention (Atlanta, Dec. 1996).

Can a society be repaired unless its killers, rapists, and torturers are named and exposed? Can it be repaired if its killers, rapists, and torturers are named and exposed? That is the overarching question of transitional justice; it may even be the overarching question of life in human society. Just as no relationship can survive in the complete absence of truth, no relationship can survive in the complete absence of …

Toward A Theory Of Reciprocal Responsibility Between Clients And Lawyers: A Comment On David Wilkins’ Do Clients Have Ethical Obligations To Lawyers? Some Lessons From The Diversity Wars, Carrie Menkel-Meadow

Georgetown Law Faculty Publications and Other Works

On my plane flight to attend the American Association of Law Schools meeting at which Professor David Wilkins presented his paper, Do Clients Have Ethical Obligations to Lawyers? Some Lessons From the Diversity Wars, the pilot requested passengers to "assist the flight attendants in their principal duty of providing safety to all passengers," following a recent incident with mid-flight turbulence in which one person died and several were injured. The pilot reminded us that "service" was only a secondary function of the flight attendants, with their principal duty being to ensure that all of us traveled and arrived safely, …

A Dual Agent Approach To Distributed Interactive Simulation Complexity, Barry L. Kelley

Link Foundation Modeling, Simulation and Training Fellowship Reports

Distributed Interactive Simulation (DIS) provides a means to create realistic, complex, virtual environments by linking together simulations of various types at multiple locations, and structuring the information exchange between the entities that comprise the simulation. The DIS methodology has demonstrated significant potential for creating virtual worlds that can simulate highly interactive activities. However, as the DIS architecture becomes more complex to support demands for more realistic simulation environments, the data transfer and processing capabilities of the supporting networks and participating simulations become limiting factors in constructing seamless, virtual environments. This document proposes a framework for a Dual Agent Architecture that …
