Measurement of the mass attenuation coefficients and electron densities for BiPbSrCaCuO superconductor at different energies
(Elsevier, 2007)
The mass attenuation coefficients for Bi, Pb, Sr, Ca, Cu metals, Bi2O3, PbO, SrCO3, CaO, CuO compounds and solid-state forms of Bi1.7Pb0.3Sr2Ca2Cu3O10 superconductor were determined at 57.5, 65.2, 77.1, 87.3, 94.6, 122 and ...
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 ...
Newly synthesized bentonite-histidine (Bent-His) micro-composite affinity sorbents for IgG adsorption
(Elsevier, 2007)
Bentonite has several advantages for use as a support, including its lack of toxicity, chemical reactivity and hydrophilicity allowing easy fixation of biomolecules. A new approach was developed to obtain an efficient and ...
Molecular characterization of antibiotic resistant Escherichia coli strains isolated from tap and spring waters in a coastal region in Turkey
(2007)
A hundred and seventeen antibiotic-resistant Escherichia coli strains were isolated from public tap and spring waters which were polluted by fecal coliforms. There were no significant differences between two water sources ...
Investigation of antibiotic resistance profile and TEM-type β-lactamase gene carriage of ampicillin-resistant Escherichia coli strains isolated from drinking water
(Springer Verlag, 2007)
Fifty-five ampicillin-resistant (Ampr) Escherichia coli strains were isolated from 51 drinking water points in Rize region containing abundant fresh water sources in Turkey during the years 2000 to 2002 and from January ...
Cloning, expression, purification and characterization of fructose-1,6-bisphosphate aldolase from Anoxybacillus gonensis G2
(2007)
The fructose-1,6-bisphosphate aldolase gene from the thermophilic bacterium, Anoxybacillus gonensis G2, was cloned and sequenced. Nucleotide sequence analysis revealed an open reading frame coding for a 30.9 kDa protein ...
Synthesis, Configuration, and Antimicrobial Properties of Novel Substituted and Cyclized ‘2′,3″-Thiazachalcones’
(Wiley, 2007)
Nine new thiazachalcone-based drugs, compounds 1-9, were prepared and fully characterized. The configurations of the photochemical-dimerization products 7-9 were rationalized by semi-empirical calculations. Both the ...
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 ...
