Indoor and outdoor gamma dose measurements for specific counties of Trabzon-Turkey
(AIP Publishing, 2010)
In this study, it was determined environmental gamma radiation dose rate for some counties of Trabzon-Turkey. A detailed ambient gamma dose measurement has been performed in the seven counties of Trabzon, using a portable ...
Variation of K X-ray fluorescence cross-sections of Cu, Y and Ba in Y Ba2Cu3O7-δ superconductor
(Elsevier, 2009)
K X-ray fluorescence cross-sections of Cu, Y and Ba elements were measured in CuO, Y 2O3, BaCO3 compounds and Y Ba2Cu3O7-? superconductor samples (nonreacted agent, calcined and sintered states). A superconductor sample ...
The effect of partial Lu doping on magnetic behaviour of YBCO (123) superconductors
(Elsevier, 2010)
We have investigated the effect of Lutetium doping on YBCO prepared by conventional solid-state reaction method by means of XRD, AC susceptibility and DC magnetization measurements and theoretical analysis. AC susceptibility ...
Measurements of some radionuclides in coffee samples using gamma-ray spectrometry and evaluating radiological health risk to the Turkish public
(Taylor & Francis Ltd., 2023)
The current research aims to assess the radioactivity levels and radiological health risks of 28 coffee samples from 21 assorted brands obtained from different provinces of Turkey. The activity concentrations of natural ...
Dynamic phase diagrams of a mixed spin-1 and spin-5/2 Ising system in an oscillating magnetic field
(2009)
We study the nonequilibrium aspects of the kinetics of a mixed spin-1 and spin-5/2 Ising system, including the biquadratic nearest-neighbor pair interaction (K) and the crystal-field interaction (D), under the presence of ...
Investigation of some superconducting properties of ytterbium diffusion-doped YBa2Cu3O7-x superconductors
(Elsevier, 2008)
The effect of Yb diffusion on structural evolution and superconducting properties of YBa2Cu307-x (Y123) prepared in the bulk polycrystalline form were studied. The ytterbium (Yb) diffusion in superconducting Y123 ceramic ...
The effective-field study of a mixed spin-1 and spin-5/2 Ising ferrimagnetic system
(2009)
An effective-field theory with correlations is developed for a mixed spin-1 and spin-5/2 Ising ferrimagnetic system on the honeycomb (?=3) and square (?=4) lattices in the absence and presence of a longitudinal magnetic ...
Determination of levitation force and pinning properties of (Sm123) 1-x(Yb211) x bulk superconductor depending on Yb211 doping ratio
(Wiley, 2009)
The vertical force density curves of (Sm123) 1-x(Yb211)x high temperature superconductor (HTS) samples prepared by a meltpowder-melt-growth technique were measured during vertical and lateral traverses in zero field cooling ...
The polarization of X-rays and magnetic photoionization cross-sections for L3 sub-shell
(Elsevier, 2009)
The alignment of atoms with inner-shell vacancies resulting from ionization by photons was investigated by measuring the anisotropic emission of L shell X-ray lines. The X-ray line intensities were measured using an Si(Li) ...
Changing the conductivity type of ultrasonically sprayed ZnO thin films: comparison of the effects of Li, N, and B dopants
(Springer, 2023)
ZnO is a material widely used in technological applications. However, the difficulty of preparing p-type ZnO creates a bottleneck for developing ZnO-based devices. In this study, Li, N, and B-doped ZnO thin films were ...
