A research on the sensitivity of European chub to some pesticides
(2006)
The aim of this study was to investigate the sensitivity of European chub (Leuciscus cephalus, Linnaeus, 1758), a natural freshwater fish species, to a synthetic pyrethroid (deltamethrin), a carbamate insecticide (carbaryl), ...
The stock parameter of anchovy (Engraulis encrasicolus) population on the coasts of the eastern black sea: Reason and implications in declining of anchovy population during the 2004-2005 and 2005-2006 fishing seasons
(0-Belirlenecek, 2008)
Some basic characteristics of anchovy (Engraulis encrasicolus) population in the Eastern Black Sea coasts were estimated in order to explain the differences seen in the catch of anchovy during the fishing seasons of 2004-2005 ...
Microwave-assisted synthesis and characterization and theoretical calculations of the first example of free and metallophthalocyanines from salen type Schiff base derivative bearing thiophen and triazole heterocyclic rings
(Elsevier, 2007)
Novel metal-free and metallophthalocyanine complexes of Co, Ni, Cu, and Zn have been synthesized by exposure to microwave irradiation and reflux conditions and the products purified by several techniques. The newly prepared ...
Determination of radioactivity levels and hazards of soil and sediment samples in Fi{dotless}rti{dotless}na Valley (Rize, Turkey)
(Elsevier, 2007)
The natural radioactivity levels in soil and sediment samples of Fi{dotless}rti{dotless}na Valley have been determined. To our knowledge, there seems to be no information about radioactivity level in the Fi{dotless}rti{dotless}na ...
Synthesis of some N-alkoxycarbonyl-N"-benzoyl-benzamidrazones(p- toluamidrazones) and 1,3,5-trisubstituted 1,2,4-triazole derivatives from N-benzoylimidates and their antimicrobial and anticancer screening studies
(Wiley, 2007)
Some new N-alkoxycarbonyl-N?-benzoyl-benzamidrazones (p-toluamidrazones) 3a-3d, and 1,3,5-trisubstituted 1,2,4-triazole 4a-4h derivatives by starting from N-benzoylbenzimidates or N-benzoyl-p-toluimidates. The structures ...
Carriage of mobilizable plasmid-mediated ?-lactamase gene in ampicillin-resistant Escherichia coli strains with origin of normal fecal flora

Synthesis and properties of triazol-5-one substituted phthalocyanines by microwave irradiation
(TÜBİTAK, 2006)
Triazol-5-one substituted phthalocyanines were prepared quickly by the reaction of 4-nitrophthalonitrile with anhydrous metal salts in DBU (1,8-diazabicyclo[5,4,0]undec-7-ene) and DMAE (dimethylaminoethanol) by microwave ...
Synthesis, crystal structure and spectroscopic studies of a mixed ligand copper (II) complex: trans-bis(succinimidato)-bis(benzylamino)Cu(II)
(Verlag der Zeitschrift fur Naturforschung, 2006)
The molecules of the title compound, [Cu(C11H13N 2O2)2], lie across centres of inversion in space group P21/c and are linked by intermolecular N-H?O and C-H?O hydrogen bonds. The central Cu atom has a slightly distorted ...
