DNA-binding properties of the bacillus subtilis and aeribacillus pallidus AC6 σD proteins
(2011)
?D proteins from Aeribacillus pallidus AC6 and Bacillus subtilis bound specifically, albeit weakly, to promoter DNA even in the absence of core RNA polymerase. Binding required a conserved CG motif within the -10 element, ...
Elliptic elements and circuits in suborbital graphs
(Hacettepe University, 2011)
We consider the action of a permutation group on a set in the spirit of the theory of permutation groups, and graph arising from this action in hyperbolic geometric terms. In this paper, we examine some relations between ...
Synthesis and biological activity studies of new hybrid molecules containing tryptamine moiety
(Springer, 2012)
The synthesis of N?-(4-substitutedphenylsulfonyl)-2-{4-[2-(1H-indol- yl)ethyl]-3-(4-chlorobenzyl)-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl} acetohydrazides (3a-c), 2-{4-[2-(1H-indol-3-yl)ethyl]-3-(4-chlorobenzyl)-5-oxo- ...
Reduction, Mannich reaction, and antimicrobial activity evaluation of some new 1,2,4-triazol-3-one derivatives
(TÜBİTAK, 2012)
Ethyl[4-arylmethyleneamino-3-(4-metylphenyl)-5-oxo-4,5-dihydro-1H -1,2,4-triazole-1-yl]acetates (3a-e and 10a-d) were obtained starting from 4-amino-2,4-dihydro-3H -1,2,4-triazol-3-ones (1 and 9) in 2 steps. The treatment ...
Antimicrobial activity and a comparative essential oil analysis of Centaurea pulcherrima Willd. var. pulcherrima extracted by hydrodistillation and microwave distillation
(Taylor & Francis Online, 2012)
The essential oils of Centaurea pulcherrima Willd. var. pulcherrima (Asteraceae) were isolated by hydrodistillation (HD) and a microwave distillation (MD), than characterised by GC-FID and GC-MS. A total of 58 and 57 ...
Poly(vinylferrocenium) perchlorate-polyaniline composite film-coated electrode for amperometric determination of hydroquinone
(Springer, 2012)
Poly(vinylferrocenium) perchlorate-polyaniline (PVF +-PANI) composite film was synthesized electrochemically on Pt electrode in a methylene chloride solution containing a mixture of poly(vinylferrocene) (PVF) polymer and ...
Variation in body size and age structure among three Turkish populations of the treefrog Hyla arborea
(Brill, 2012)
To determine how climate factors influence age, body size and sexual size dimorphism (SSD) in the Mediterranean region, we generated data on age and body size of the European Treefrog, Hyla arborea, in three Turkish ...
Radioactivity and heavy metal concentrations in food samples from Rize, Turkey
(Wiley, 2012)
BACKGROUND: Rize in Turkey was contaminated by the Chernobyl accident in 1986. A comprehensive study was planned and carried out to determine the radioactivity levels and heavy metal concentrations in four food categories ...
Chemical constituents and antimicrobial activity of the essential oil from vicia dadianorum extracted by hydro and microwave distillations
(2012)
The aim of this research was to investigate the influence of extraction methods on yield and chemical composition of the essential oil of Vicia dadianorum Somm. & Lev. The volatiles of V. dadianorum have been isolated by ...
Current transport mechanism in CdS thin films prepared by vacuum evaporation method at substrate temperatures below room temperature
(Elsevier, 2012)
CdS thin films were deposited by vacuum deposition method at low substrate temperatures instead of the commonly used vacuum deposition at high substrate temperatures (T S > 300 K). The effect of low substrate temperature ...
