Ni(II), Cu(II), and Zn(II) complexes of tetradentate schiff base containing two thiadiazoles units: Structural, spectroscopic, magnetic properties, and molecular modeling studies
(Wiley, 2008)
Four new mononuclear metal complexes with a mononucleating Schiff base ligand containing two thiadiazoles units have been synthesized. The ligand and metal complexes were characterized by elemental analyses, IR, 1H, and ...
A comparative study on two closely relative Tulipa L. taxa from NE Anatolia
(Springer, 2008)
This study presents observations on the anatomical, palynological and ecological features of Tulipa gumusanica Terzioğlu and its morphologically similar relative, T. armena Boiss. var. armena, in order to clarify their ...
Physiological changes in them in post-stress emerging Ctenanthe setosa plants under drought conditions
(Maik Nauka-Interperiodica Publishing, 2008)
The capability of Ctenanthe setosa (Rosc.) Eichler (Marantaceae), pre-exposed to severe drought stress, of adaptation to a new drought conditions was investigated. C. setosa unstressed plants were exposed to drought period ...
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 ...
