The Peculiarities Of The Electrical And Thermoelectrical Properties Of P-Type Ag_2te, Ali̇ İhsan Demi̇rel, S. A. Aliev, F. F. Aliev, F. Z. Guseynov, Sali̇m Orak
The Peculiarities Of The Electrical And Thermoelectrical Properties Of P-Type Ag_2te, Ali̇ İhsan Demi̇rel, S. A. Aliev, F. F. Aliev, F. Z. Guseynov, Sali̇m Orak
Turkish Journal of Physics
The electrical and thermoelectrical properties of p-type Ag_2Te have been investigated. Various peculiarities were observed: the minimum (at T \approx 65 K) and maximum (at T \approx 200 K) on the temperature dependence of conductivity \sigma (T); the weak dependence of Hall coefficient R(T) (in 200-300 K range) and the maximum (at T \approx 100 K and 250 K) on the temperature dependence of thermal power \alpha_0 (T). The investigation results were interpreted by two-bands model. It is shown that mentioned peculiarities have been stimulated by the narrow gap of Ag_2Te and its temperature dependence.

Supersymmetric Electroweak Radiative Corrections To E^+ E^- -> W^+W^-, S. Alam
Supersymmetric Electroweak Radiative Corrections To E^+ E^- -> W^+W^-, S. Alam
Turkish Journal of Physics
In this short note we summarize some of the work of our thesis, which is also reported elsewhere in detail. We have examined the one loop quantum corrections to the W pair production in the electron positron annihilation in the context of supersymmetric electroweak theory. We have adopted the On Mass Shell Renormalization scheme of Sakakibara and previously demonstrated the consistency of this scheme. The relevant analytic results are written out. A complete computer program for these corrections has been developed. This program has been checked in several ways to ensure against errors over the life of the calculation where …
Effect Of Illumination Temperature On Thermally Stimulated Current Spectrum Of Tlins_2, Selahatti̇n Özdemi̇r, Rauf Süleymanov, Mahmut Bucurgat, Enver Bulur
Effect Of Illumination Temperature On Thermally Stimulated Current Spectrum Of Tlins_2, Selahatti̇n Özdemi̇r, Rauf Süleymanov, Mahmut Bucurgat, Enver Bulur
Turkish Journal of Physics
The effect of pre-illumination on both thermally stimulated current and photocurrent spectra of TlInS_2 crystal is investigated. The increase in the photosensitivity of the crystal by several orders of magnitude together with the appearance of a new peak in the thermally stimulated current spectrum are observed as a result of the pre-illumination process. The filling of the traps, especially the sensitizing centers, during the pre-illumination is found to be the most favourable physical mechanism to explain the results.
Confined Bipolarons In The Strong Coupling Limit, R. Tuğrul Senger, Ati̇lla Erçelebi̇
Confined Bipolarons In The Strong Coupling Limit, R. Tuğrul Senger, Ati̇lla Erçelebi̇
Turkish Journal of Physics
Within the framework of the strong-coupling polaron theory and the bulk phonon approximation we report the possibility and criteria in achieving stable bipolaron states in confined media. We use a simple model of two electrons constrained within an anisotropic three dimensional parabolic potential box of tunable barrier slopes. Conforming the confining potential from one geometry to the other, we obtain an explicit tracking of the stability criteria as a function of the degree of confinement uncovering all low dimensional major geometric configurations of common interest.
Implications Of \Delta\Rho And Charm Ii Data For Z' Physics, Durmuş Ali̇ Demi̇r
Implications Of \Delta\Rho And Charm Ii Data For Z' Physics, Durmuş Ali̇ Demi̇r
Turkish Journal of Physics
We discuss the constraints on the Z^{\prime} model parameters coming from Z-pole and low-energy \nu_{\mu}-e scattering data in the frame work of GUT-motivated models. We find that when the coupling constant of the extra U(1) is small (large) the parameter space is mainly determined by the Z-pole (the low-energy \nu_{\mu}-e scattering) data.
Electroweak Symmetry Breaking In Low-Scale Quantum Gravity, M. Boz, A. Demi̇r, Namik Kemal Pak
Electroweak Symmetry Breaking In Low-Scale Quantum Gravity, M. Boz, A. Demi̇r, Namik Kemal Pak
Turkish Journal of Physics
We discuss the implications of low-scale quantum gravity on electroweak symmetry breaking by computing one-loop gravitational corrections to the Higgs potential. We conclude that these radiative corrections are quite large after summing over the graviton and dilaton Kaluza-Klein towers, and there is no possibility of electroweak symmetry breaking unless one allows for the complex vacuum expectation value for the Higgs field.
Projectile Fragmentation In Emulsion At (4.1-4.5) A Gev/C, A. El-Naghy, S. A. H. Abou-Steit, M. Mohery
Projectile Fragmentation In Emulsion At (4.1-4.5) A Gev/C, A. El-Naghy, S. A. H. Abou-Steit, M. Mohery
Turkish Journal of Physics
The fragmentation process has been investigated for 4.5A GeV/c^{28}Si nuclei in emulsion and compared with the results of 4.5A GeV/c^{24}Mg and 4.1A GeV/c^{22}Ne in order to test the validity of the different theoretical models. It has been found that a single parameter distribution is insufficient to explain exactly the fragmentation process. Correlation studies have shown to be necessary for distinguishing between the different theoretical models for the fragmentation. The impact parameter, which defines the nature of the collision, has been found to influence considerably the shape of the charge yield distribution. The angular distributions of the projectile fragments can be …
Electrodynamics With Toroid Polarization, V. M. Dubovik, B. H. Saha
Electrodynamics With Toroid Polarization, V. M. Dubovik, B. H. Saha
Turkish Journal of Physics
A modified system of equations of electrodynamics of continuous media has been obtained. Beside the Lagrangian system an alternative gauge-like formalism has been developed to introduce the toroid moment contributions in the obtained equations. The two potential formalism that was worked out by us earlier has been developed further where along with the two vector potentials we introduce two scalar potentials thus taking into account all four basic equations of electromagnetism.

Stellar Observations Made At The Malatya Danjon Astrolabe Station, Orhan Gölbaşi, Hüseyi̇n Kiliç, Fernand Chollet
Turkish Journal of Physics
We give here the first results of astrometric stellar observations made at the Malatya Station with the modified astrolabe of Paris observatory. This campaign is conducted as part of a cooperation between Inönü University and the Paris Observatory. The astrolabe, which is strictly similar to that of Santiago de Chile, can use two reflecting prisms instead of the trnsparent prism of the Danjon Astrolabe. Consequently, it is possible to observe at the two zenith distances of 30° and 60°. The time is supplied by a GPS receiver which gives UTC with the necessary precision. As the station is a new …
Canonical Treatment Of Regular Lagrangians With Holonomic Constraints As Singular Systems, Eqab M. Rabei
Canonical Treatment Of Regular Lagrangians With Holonomic Constraints As Singular Systems, Eqab M. Rabei
Turkish Journal of Physics
Regular Lagrangians with holomonic constraints are treated as singular systems using the canonical method. The Lagrange multipliers are introduced as generalized coordinates. The regular Lagrangians are extended to be singular and the Hamiltonian formulation is obtained. The equations of motion are written as total differential equations in terms of the time t and the Lagrange multipliers. It is also shown that Lagrange multipliers can be determined from the integrability conditions.
Magnetisation In Two-Dimensions, Bengü Kaplan
Magnetisation In Two-Dimensions, Bengü Kaplan
Turkish Journal of Physics
We discuss the magnetisation deviation in two-dimensions (2d) for an iron film for which the anisotropy is much smaller and hence the magnetisation is a stronger function of temperature. The magnetisation deviation can be adequately described by an RPA (random phase approximation) approach. Our results fit the experimental data at high fields and hence can be used to estimate the value of the effective exchange interaction (J_{2d}) for monolayer (ML) films.

A Magnetization And Gmr Study On Multilayered Fe/Ag/Co Thin Film, Cengi̇z Bi̇rli̇kseven, Alpan Bek, Hüseyi̇n Zafer Durusoy
Turkish Journal of Physics
Single layer Fe(20Å) and Co(20Å) and multilayered Ag(20Å)/[Fe(20Å)/Ag(40Å)/Co(20Å)/Ag (40Å)] x 3/Ag(20Å) films were prepared in UHV by magnetron sputtering technique onto the silicon substates. Films were determined to have polycrystalline nature through SEM examination. Magnetization measurements were made on single and multilayer films. Due to the polycrystalline structure of the films, rounded magnetization curves were obtained. The GMR effect showed a rounded behaviour which also is an indication of the polycrystallinity of the films. The GMR effect, measured in Fe/Ag/Co multilayer structure, was analyzed with the help of magnetization behaviour of the multilayer structure and magnetization behaviour of the single …

Low-Magnetic Field Microwave Absorption In Superconductors And Conducting Polymers, I. L. Khairullin, P. K. Khabibullaev, V. Yu. Sokolov, A. A. Zakhidov
Turkish Journal of Physics
Low-magnetic field microwave absorption (MA) in superconductors and conducting polymers is analysed in a low-field signal (LFS) version of the MA detecting method. The temperature dependences, hysteretic benavior and other properties of a LFS are compared in superconducting versus non-superonducting systems. Spin selective hopping processes between polarons and bipolarons is proposed to be one of the possible mechanisms of a LFS in non-degenarate conducting polymers.

A Study On The Phytoplankton Of Hasan Uğurludam Lake (Samsun-Turkey), Arif Gönülol, Olcay Obali
Turkish Journal of Biology
The composition and seasonal variations of phytoplankton of Hasan UGURLU Dam Lake were studied using samples collected from two stations between July 1992 to December 1993. 57 taxa were identified belonging to the Bacillariophyta, Chlorophyta, Cyanophyta, Dinophyta and Euglenophyta divisions of phytoplankton. In the phytoplankton, Asterionella formosa, Cyclotella planc-tonica, Pediastrum simplex and Ceratium hirundinella caused water blooms in certain months. The light density and temperature affected the composition and seasonal variations in phytoplankton considerably. Nutrient levels in the lake did not limit the seasonal variations in phytoplankton. It was determined that Lake Hasan Ugurlu had mesotrophic characteristics because of the …

Turkish Journal of Physics
We discuss the production of several SUSY particles in the high energy collisions of the real photons off the protons within the MSSM. The polarizations of the colliding beams are also considered. The discovery mass limits for the squark and gluinos are presented and we conclude that the capacity of the future TeV scale $\gamma p$ colliders is quite promising in the search for SUSY particles.
Resummation Of Ir Renormalons In A Single Meson Photoproduction, Shahin S. Agaev
Resummation Of Ir Renormalons In A Single Meson Photoproduction, Shahin S. Agaev
Turkish Journal of Physics
Single pseudoscalar and vector mesons hard semi-inclusive photoproduction $\gamma h\rightarrow MX $ via higher twist mechanism is calculated using the QCD running coupling constant method. It is proved that in the context of this method a higher twist contribution to the photoproduction cross section cannot be normalized in terms of the meson electromagnetic form factor. The structure of infrared renormalon singularities of the higher twist subprocess cross section and the resummed expression (the Borel sum) for it are found. Comparisons are made with earlier results, as well as with leading twist cross section. Phenomenological effects of studied contributions for $\pi, …
