Dependency of c-lattice parameter, activation energy and its magnetic power constant on x in Y1-xYbx/2Gdx/2Ba2Cu3O7-y superconductors
(Elsevier, 2008)
To investigate the effect of x on c-lattice parameter, the activation energy, and the magnetic power constant of activation energy, the nominal composition of Y1-xYbx/2Gdx/2Ba2Cu3O7-y superconducting samples for x = 0.0, ...
Synthesis and antimicrobial evaluation of novel di-triazoles and 4-arylidene amino 4,5 dihydro-1H-[1,2,4] triazole-5-one derivatives
(TUBİTAK, 2008)
A series of novel di-[3(thiophen-2-yl-methyl)-4,5-dihydro-1H-[1,2,4] triazole-5-one-4yl]n-alkanes (2a-h) were obtained by the reaction of N'-1-ethoxy-2-thiophen-2-yl-ethylydene hydrazino carboxylic acid ethyl ester (1) and ...
Luciobarbus kottelati, a new species of barbel (Teleostei: Cyprinidae) from the Büyük Menderes River, Turkey, with rediagnose of L. lydianus
(Magnolia Press, 2008)
Luciobarbus kottelati, new species, is described from the River Büyük Menderes, Aegean Sea drainage, Turkey. It is distinguished from all other species of Luciobarbus in Europe and western Anatolia by the pelvic-fin origin ...
Gadolinium diffusion-doping for enhancing activation energy in superconducting YBa2Cu3O7-x
(Elsevier, 2008)
The resistance transitions of Gd-diffused polycrystalline Y123 samples have been measured as a function of temperature and magnetic field. It is deduced from experimental results that the activation energy increases when ...
Investigation of the dependency of the upper critical magnetic field on the content x in Y1-xYbx/2Gdx/2Ba2Cu3O7-y superconducting structures
(Elsevier, 2008)
The Y1-xYbx/2Gdx/2Ba2Cu3O7-y superconducting samples for x = 0.0, 0.2, 0.4, 0.6, 0.8 and 1.0 were prepared by using the solid-state reaction technique. Resistivity measurements of the samples were performed in QD-PPMS ...
Phenolic acid contents of kale (Brassica oleraceae L. var. acephala DC.) extracts and their antioxidant and antibacterial activities
(Elsevier, 2008)
Nine phenolic acids were identified and quantified by HPLC-MS in leaves and 10 in seeds of kale (black cabbage). The free, ester (methanol-soluble), glycoside and ester-bound (methanol-insoluble) phenolic acid contents of ...
5,5-Diethylbarbiturate complexes of silver with 2,2′-bipyridine and 3-(2-pyridyl)propanol: Syntheses, crystal structures, spectroscopic, thermal and antimicrobial activity studies
(Verlag der Zeitschrift fur Naturforschung, 2008)
Two silver 5,5-diethylbarbiturate (barb) complexes with 2,2?-bipyridine (bpy) and 3-(2-pyridyl) propanol (pypr), [Ag(barb)(bpy)] (1) and [Ag(barb)(pypr)] (2), have been prepared and characterized by elemental analysis, IR ...
Cloning, expression, purification and characterisation of a thermostable chitinase from Bacillus licheniformis A1
(University of Milan, 2008)
The chitinase B gene (ch/B65) of Bacillus licheniformis A1 (BlicA1) isolated from Diyadin hotspring in Turkey was cloned and sequenced. The gene is 1779 bp long and encodes a protein 592 amino acids with a 35-amino acid ...
Coupled longshore and cross-shore models for beach nourishment evolution at laboratory scale
(ASCE Library, 2008)
A series of three-dimensional laboratory experiments on beach nourishment behavior are described and analyzed. The experiments were designed to isolate the influences of berm height, beachfill median grain size, wave height, ...
Synthesis and anticancer evaluation of some new 4-amino-3-(p-methoxybenzyl) -4,5-dihydro-1,2,4-triazole-5-one derivatives
(Verlag der Zeitschrift fur Naturforschung, 2008)
4-Amino-3-p-methoxybenzyl-5-oxo-4,5-dihydro-1,2,4-triazol-1-yl-acetic acid ethyl ester (2) was prepared from 4-amino-4,5-dihydro-1H-1,2,4-triazole-5-one (1) and ethyl bromoacetate. Compound 3 was synthesized by the ...
