Fatty acid and amino acid compositions of cultured and wild sea bass (Dicentrarchus labrax L., 1758) from different regions in Turkey
(2009)
The main aim of this research is to determinate the fatty and amino acid alternations of cultured and wild sea bass (Dicentrarchus labrax) flesh obtained from different regions of Turkey. The major fatty acids of sea bass ...
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 ...
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 ...
The atlantic starfish, Asterias rubens Linnaeus, 1758 (Echinodermata: Asteroidea: Asteriidae) spreads in the Black sea
(Regional Euro-Asian Biological Invasions Centre, 2009)
A single specimen of Asterias rubens was collected on 17 February 2009 off Karasu, Sakarya, Turkey. Its possible impact on Mytilus galloprovincialis beds in the Black Sea is discussed. © 2009 The Author(s).
Synthesis of some new 1,3,4-thiadiazol-2-ylmethyl-1,2,4-triazole derivatives and investigation of their antimicrobial activities
