Anatomical and pollen characters in the Genus epilobium L. (Onagraceae) from Northeast Anatolia
(2008)
Anatomical and palynological features of E. algidum Bieb., E. palustre L., E. ponticum Hausskn., E. confusum Hausskn., E. hirsutum L. and E. montanum L. collected from NE Anatolia were examined and evaluated by numerical ...
Microwave-assisted synthesis and antifungal activity of some new 1H-1,2,4-triazole derivatives
(Springer, 2008)
A number of 3-aryl-4-arylmethylideneamino-4,5-dihydro-1H-1,2,4-triazol-5- ones were synthesized by reaction of the corresponding aromatic aldehydes with 4-amino-3-aryl-1H-1,2,4-triazol-5-ones in anhydrous ethanol under ...
Binuclear transition metal complexes of a novel lateral ‒N-methylthiosemicarbazone through the central ethylene bridge: Synthesis, structural characterization and the response of ligand molecule to different solvent media
(Elsevier, 2008)
The condensation of 2,2?-(2,3-bis((1-formylnaphthalen-2-yloxy)methyl)but-2-ene-1,4-diy l)bis(oxy)di-1-naphthaldehyde with 4-methyl thiosemicarbazide gave a novel N-methylthiosemicarbazone and then the reaction of this ...
Foliar resorption of nutrients in selected sympatric tree species in gallery forest (black sea region)
(2008)
Gallery forests in Central Black Sea Region are dominated by Platanus orientalis L. The studies were performed in four sites (Mert River, Adalar, Kurupelit and Taflan Regions) located in V-shaped river valleys and differing ...
Assessment of metal element concentrations in mussel (M. Galloprovincialis) in Eastern Black Sea, Turkey
(Elsevier, 2008)
The main goal of this work is to determine the effects of pollution of copper, lead and zinc mines on the Eastern Black Sea. Metal and heavy metal concentrations in the Eastern Black Sea mussels were measured using Energy ...
Microwave-assisted synthesis of 4′-azaflavones and their n-alkyl derivatives with biological activities
(Wiley, 2008)
4?-Azaflavone (=2-(pyridin-4-yl)-4H-1-benzopyran-4-one; 4) and 3-[(pyridin-4-yl)methyl]-4?-azaflavone (5) were synthesized by a simple environmentally friendly microwave-assisted one-pot method through the cyclization of ...
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, ...
