Family of surface with a common null geodesic
(2009)
We analyzed the problem of finding a surfaces family through a null curve with Cartan frame. We constructed a differential equation system such that a given null curve is an isogeodesic curve on a surface. In addition, ...
Synthesis of 1,2,4-Triazole derivatives and determination of protonation constant
(2009)
A microwave irradiation method has been developed for the synhesis of some 1,2,4-triazole derivatives using environmentally benign solvent ethanol in open vessels. Twelve 1,2,4-triazole derivatives were synthesized in good ...
Class 1 and class 2 integrons and plasmid-mediated antibiotic resistance in coliforms isolated from ten rivers in northern Turkey
(2009)
We aimed to determine the molecular mechanisms of antibiotic resistance in coliforms isolated from ten rivers in northern region of Turkey. A total of 183 isolates were tested for antimicrobial susceptibility by disk ...
Determination of adsorptive properties of a Turkish Sepiolite for removal of Reactive Blue 15 anionic dye from aqueous solutions
(Elsevier, 2009)
Reactive Blue 15 (RB 15) adsorption on the Turkish Sepiolite was carried out by batch equilibrium technique. IR spectrum and surface area measurement of the composite of dye-sepiolite (Turkish) pointed out that dye species ...
Reversible immobilization of catalase by using a novel bentonite-cysteine (Bent-Cys) microcomposite affinity sorbents
(Elsevier, 2008)
This study focused on developing bentonite-cysteine (Bent-Cys) microcomposite affinity sorbents (38-105 ?m) for catalase adsorption from aqueous solutions. Pseudo-biospecific affinity ligand l-cysteine was covalently binded ...
3-Ethyl-4-(p-chlorobenzylidenamino-4,5-dihydro-1H-1,2,4-triazol-5-one (EPHBAT) as precipitant for carrier element free coprecipitation and speciation of chromium(III) and chromium(VI)
(Elsevier, 2009)
A method for the separation and speciative determination of Cr(VI) and Cr(III) has been developed. The procedure is based on coprecipitation of Cr(III) on 3-ethyl-4-(p-chlorobenzylidenamino-4,5-dihydro-1H-1,2,4-triazol-5-one ...
The influence of substrate temperature on the morphology, optical and electrical properties of thermal-evaporated ZnTe Thin Films
(Elsevier, 2009)
The structural, morphological, optical and electrical properties of ZnTe films deposited by evaporation were investigated as a function of substrate temperature (at -123 and 27 °C) and post-deposition annealing temperature ...
PCR based idendification and discrimination of Caranx rhonchus (Pisces, Carangidae) based on nuclear and mtDNA sequences
(2009)
PCR based nuclear and mitochondrial DNA markers are used to clarify cases of misidentification of adult individuals of fish species with morphological similarities. This problem prevails in the case of false scad (Caranx ...
