AC losses in a commercial Bi: 2223/Ag tape
(Institute of Physics Publishing, 2009)
We have investigated the effect of temperature, field amplitude, frequency and orientation of the field on AC losses in a commercial Bi:2223/Ag tape. The measurements were performed using an AC susceptometer. The experimental ...
Effects of x in Yb1-xGdxBa2Cu3O7-y samples on c-lattice parameter, activation energy and its magnetic power constant
(Elsevier, 2008)
The Yb1-xGdxBa2Cu3O7-y superconducting samples (x = 0.0, 0.2, 0.4, 0.6, 0.8 and 1.0) which were prepared by solid-state reaction technique were studied to investigate the effect of x on c-lattice parameter, the activation ...
Investigation of effect of x in Yb1-xGdxBa 2Cu3O7-y superconducting structures on upper critical magnetic field and coherence length
(Institute of Physics Publishing, 2009)
The resistivity measurements of the Yb1-xGdxBa 2Cu3O7-y superconducting samples prepared by using the solid-state reaction technique for x=0.0, 0.2, 0.4, 0.6, 0.8 and 1.0 were performed in QD-PPMS system under different ...
Development and situation of trout culture in turkey
(Jelgava : Latvia University of Agriculture, 2009)
The production of rainbow trout (Oncorhynchus mykiss) is developing and it is most cultured finfish species in Turkey. It was first introduced in Turkey in the mid 1970s from Italy. In the following years, culture studies ...
Coupled-channel and distorted-wave Born approximation analyses for 25.1 MeV and 32.5 MeV energies of p- 40Ar inelastic scattering
(Springer, 2008)
The optical model parameters, the coupled-channel parameters and excitation mode ?2 , ?3 and ?5 deformation parameters corresponding to the best fit to the experimental differential cross-sections and the analyzing powers ...
Anomalous ferromagnetic behaviour of Y2O3 and CuO nanoparticles in YBa2Cu3Oy superconductor
(Institute of Physics Publishing, 2009)
Anomalous ferromagnetic behaviour of the Y2O3 and CuO components in YBa2Cu3Oy (Y123) was observed after severe reduction of particle size. The particle size reduction was performed in following way: Y2O3, BaCO3 and CuO ...
Capoeta erhani, a new species of cyprinid fish from Ceyhan River, Turkey (Teleostei: Cyprinidae)
(2008)
Capoeta erhani, new species, is described from the Ceyhan drainage, eastern Anatolia. It is distinguished from the other members of the C. trutta species-group (Capoeta species with numerous irregular black spots on the ...
