The activation energy for indentation creep of the crystals has been evaluated.

Solar Observations Made At The Malatya Station With Danjon Astrolabe, Orhan Gölbaşi, Hüseyi̇n Kiliç, Fernand Chollet

Turkish Journal of Physics

The first results of astrometric solar observations made at the Malatya Station with a modified version of the Paris Observatory astrolabe are presented. This campaign was conducted as part of a cooperation between Inonü University and the Paris Observatory. The astrolabe, exactly the same as the one at Santiago de Chile [1], uses two reflecting prisms instead of transparent prisms in order to be able to observe at two zenith distances of 30^o and 60^o. The time is supplied by a Global Positioning System (GPS) receiver. The measurements (Table 1, 2) made between 1993 and 1994, were used in obtaining …

Thickness Dependence Of C/A Polytwin Structures Observed In Epitaxial Oxide Ferroelectric Thin Films, S. Pami̇r Alpay, Alexander L. Roytburd

Turkish Journal of Physics

Ferroelectric or ferroelastic epitaxial films undergoing a cubic-to-tetragonal phase transformation usually relax the resultant strain energy due to lattice misfit by forming a polytwin (polydomain) structure. Polydomain formation occurs at the expense of building interdomain interfaces and microstresses which develop at the film-substrate interface due to the periodic deviation of the strain. The interplay between these components results in a critical thickness for domain formation below which the polydomain structure is not stable. In this article, we investigate the film thickness dependence of a polydomain structure using a thermodynamical approach.

The Interaction Of The Dipole Moment Of The Water Molecule With The Interface States Of The Cuprous Oxide/Cupric Oxide Junction, Necmi̇ Seri̇n, Tülay Seri̇n, Basri̇ Ünal

Turkish Journal of Physics

An Au/CuO/Cu$_{2}$O/Cu sandwich structure has been obtained by growing successive Cu$_{2}$O and CuO layers on a Cu sheet. A gold metal contact was formed CuO side at pressure of $1\times10^{-6}$ Torr. Current-voltage characteristics and capacitance of the system were seen to change over a great extent due to the presence of humidity. The effect of the humidity on Au/CuO/Cu$_{2}$O/Cu is explored through the effect of water's dipole moment.

Two-Photon Absorption In Size-Quantized Semiconductors With Degenerated Valence Band, T. G. Ismailov, M. A. Bagirov, B. Ünal

Turkish Journal of Physics

Two photon absorption in size-quantized films of semiconductors with degenerated band structures are investigated. The carrier energy spectrum and wavefunctions in the bands are calculated using two-band Kane model with spin taken into accont. Two-photon absorption coefficients for different polarizations of incident radiations are calculated. The strong dependence of two-photon absorption on polarizations are stated.

Canonical Quantisation Of The Sl(2,R)/ U(1) Gauged Wznw Black Hole Model, Christopher Ford, George Jorjadze, Gerhard Weigt

Turkish Journal of Physics

Gauged WZNW models are integrable conformal field theories with non-local canonical free-field transformations. Canonical quantisation requires quantum deformations.

Gauge Transformations In General Relativity - A Report, L. C. Shepley, J. M. Pons, D. C. Salisbury

Turkish Journal of Physics

We take as our basic principle that the Lagrangian and the Hamiltonian formulations of general relativity should be equivalent. It is then possible to choose the gauge transformations so as to be projectable under the Legendre map from configuration-velocity space (the tangent bundle) to phase space (the cotangent bundle). This projectability requirement then implies that gauge transformations in general relativity (we study in particular spacetimes with a Yang-Mills field) must depend in a specific way on the lapse and shift of the metric. This talk outlines the arguments and presents some of the results of the application of these principles.

The Radius Cutoff For Relativistic Clusters, M. Hafizi

Turkish Journal of Physics

In this work we consider an isothermic relativistic kinetic gas under relativistic conditions, as a model for high center density galaxies. We apply the radius cutoff of the Emden type, in order to remove infinities. Numerically we find some theoretical configurations with very high values of masses concentrated in small volumes. Profiles of some thermodynamic quantities such as density, presure, will be independent from the choice of radius cutoff, whereas temperature and gravitational potential depend essentially on the cutoff value.

Associations Of X-Ray Binaries With Open Clusters And Supernova Remnants, Eni̇s Tuncer, H. Guseinov, Ü. Kiziloğlu, A. O. Allakhverdiev

Turkish Journal of Physics

Searching for X-ray binaries projected on open clusters (OCs) and supernova remnants (SNRs), associations of X-ray binaries with OCs and SNRs in the Galaxy are discussed. Three of the high mass X-ray binaries (HMXBs) and four of the low mass X-ray binaries (LMXBs) are projected on open clusters. Five of HMXBs and six of LMXBs are projected on SNRs. The number of the HMXB projections are less than the LMXBs, which is not expected and is surprising since the objects in this study, except the LMXBs, are all young objects. Such associations help us improve distance and age estimates of …

Ferromagnetic Transitions In Ni-Mn Alloys, F. Boakye, R. K. Nkum

Turkish Journal of Physics

Ferromagnetic transitions in nickel and nickel-manganese alloys have been studied using resistivity-temperature measurements from 800 to 77 K. The results establish the transition temperature of nickel as 610 K and the transition temperature is shifted to lower values as the concentration of Mn in the alloy is increased. Analysis of the resistivity results near the ordering temperature \( (T

A Guide To Avpri Materials On Russian Consuls And Commerce In The Near East, Theophilus C. Prousis

History Faculty Research and Scholarship

Tsarist expansion against the Ottoman Empire and commercial access to the Black Sea and the Mediterranean broadened the parameters of Russian influence in the Near East in the nineteenth century. For Imperial Russia, the Eastern Question became a complex and multi-faceted issue, encompassing the pursuit of strategic and diplomatic aims in Istanbul, the Straits, and the Balkan peninsula, the protection of Eastern Orthodoxy, and the extension of trade in the Black Sea and the Levant. Commerce and consuls provide windows on Russia’s interaction with the Near East and illuminate the variety of interests which comprised Russia’s Eastern Question.

Cross-Cultural Interpretations Of Fraud: An Attitudinal Study In A Middle Eastern Multinational Corporation, Douglas Moore Watson

Harold L. Hodgkinson Award for Outstanding Dissertation

This research tested the theory that cultural heritage affects attitudes toward business-related fraud and, as a consequence, influences ethical decisions. A sample of 695 white-collar employees from a Middle Eastern multinational corporation (MNC), who represented nine world cultures, were asked to evaluate scenarios describing five business frauds--bribery, conflict of interest, embezzlement, management fraud, and industrial espionage--against a 7-point Likert-type scale that measured levels of approval. Analysis of variance (ANOVA) of the responses revealed those claiming African, Caribbean/South American, European, Middle Eastern, and North American cultural heritage viewed fraudulent behavior with a greater degree of disapproval than did those claiming Asian, …

Interaction Between Cesium Chloride Molecules And Metal Atoms Under Coadsorption On A Single Graphite Layer On Iridium, N. M. Nasrullaev

Turkish Journal of Physics

Using the method of continuos flow to investigate the kinetics of reaction between atoms and molecules, the efficiency of substitution reactions (K, Na, Li)+ CsCl is shown to decrease. The efficiency is found to strongly depend on temperature tending to saturation with decreasing temperature. This fact is in accordance with Bonzel's concept.

Thermal Stability Of Fe_{85.5}B_{14.5} Metallic Glass, Asghari Maqsood, Ashfaq Ahmad

Turkish Journal of Physics

The thermal stability and crystallization behaviour of metallic glass Fe\( _{85.5} \)B\( _{14.5} \) were investigated by Dynamic Temperature Resistivity Measurement (DTRM) technique from room temperature to 1050K in forward and reverse mode at a heating rate of 40 K/hr. The slope of Resistivity-Temperature-Curve (RTC) changes sign and magnitude at the temperature where the transition takes place. Differential Thermal Analysis (DTA) was carried out at the heating rates of 10, 20, 30 \& 40 K/min. A comparison of the results of DTRM and DTA measurements shows that crystallization in this alloy is two-stage process. Activation energy for two crystallization steps …

Radioluminescent Properties Of Cds(Ag) Crystals, Ruhi̇ Kaplan, F. Esen Özsan

Turkish Journal of Physics

The radioluminescent proporties of silver-doped cadmium sulphide, CdS(Ag), crystals excited by 5.5 MeV $ \alpha $-particles from an $ ^{241}$Am radioactive source have been investigated. The emission spectra, decay profiles and thermal quenching curves were obtained accurately at temperatures between 80 K and 300 K. Two main radioluminescent emission bands centered at about 5760 \AA\ and 5940 \AA\ were observed. Their decay curves were found to be fast and nonexponential. From the thermal quenching of radioluminescence, the activation energies of centers responsible for these emissions were determined. The results are interpreted as the radioluminescence is possibly due to donor-acceptor pair …

K-Vacancy Production In The Collision Of Highly Charged Relativistic Ions With Heavy Atoms, P. K. Khabibullaev, V. I. Matveev, D. U. Matrasulov

Turkish Journal of Physics

A general expression for the cross section of the inelastic collision of relativistic highly charged ion with heavy (relativistic) atoms is obtained using the generalized eikonal approximation. In the ultrarelativistic limit, the obtained formula coincides with a known exact one. As an application of the obtained result, probability and cross section of the K-vacany production in the $U^{92+} - U^{91+}$ collision are calculated.

Barrier Heights Of Antimony / And Bismuth / P -Silcon (100) Junctions, A. A. Oberafo, A. Z. Ziriki

Turkish Journal of Physics

Junctions were fabricated in vacuum of about $10^{-5}$ Torr by thermal evaporation of Sb or Bi onto chemically etched $p$-type silicon (100) substrates. The electrical properties were studied by current voltage (I-V) measurements. Some of the Sb and Bi junctions were heated-treated for $\frac{1}{2}$ hr at 200 and 150^oC, respectively. The barrier height (BH) was equal to 0.64 eV for both as-deposited and heat-treated Sb junctions, while it was 0.56 and 0.74 eV for as-deposited and heat-treated Bi Junctions, respectively. These observatimons indicate that for Sb junctions, annealing at a temperature of 200^oC resulted only in partial elimination of any …
