In vitro antioxidant and acidic properties of novel 4-(5-Methyl- 24hienylmethyleneamino)-4,5-dihydro-1H-l,2,4-triazol-5one derivatives. Synthesis and characterization
(Syscom 18 SRL, 2012)
In the present study 3-alkyl(aryl)-4-amino-4,5-dihydro-1H-l,2,4-triazol-5- ones 2a-i reacted with 5-methylthiophene-2-carboxyaldehyde to afford the corresponding compounds 3a-i and the acetylation reactions of compounds ...
The tritium, deuterium and oxygen-18 isotope levels determination in various waters in Rize and Trabzon
(Taylor and Francis Inc., 2012)
Rize and Trabzon are provinces at north-east site of Turkey, on the eastern Black Sea coast. There has been no information about isotopic ?18O, ?D and tritium determination reported in water samples in the Rize and Trabzon ...
Design and synthesis of some azole derivatives as potential antimicrobial agents
(Birkhauser Boston, 2012)
Syntheses of 1,2,4-triazol-3-ones, 4a, 4b, and 5 were performed starting from ester ethoxycarbonylhyd-razones (1a, 1b) that were reported earlier. The treatment of triazole derivatives, 4a, 4b, and 5 with several sulfonyl ...
Bacteria from Ips sexdentatus (Coleoptera: Curculionidae) and their biocontrol potential
(Wiley, 2012)
Ips sexdentatus (Coleoptera: Curculionidae) is one of the most destructive pests of the spruce trees in Europe. In this study, we have isolated and characterized culturable bacteria from I. sexdentatus and tested their ...
Microscopic study of Ca + Ca fusion
(American Physical Society, 2012)
We investigate the fusion barriers for reactions involving Ca isotopes 40Ca+40Ca, 40Ca+48Ca, and 48Ca+48Ca using the microscopic time-dependent Hartree-Fock (TDHF) theory coupled with a density constraint. In this formalism ...
A new Scorzonera (Asteraceae) species from south Anatolia, Turkey, and its taxonomic position based on molecular data
(Turkiye Klinikleri, 2012)
Scorzonera zorkunensis Coskuncelebi & S.Makbul (Asteraceae) is described and illustrated from Turkey. It grows on serpentine in alpine steppe vegetation together with several endemic Scorzonera L. species in southern ...
Karyology of the Scorzonera L. (Asteraceae) taxa from Turkey
(Scientific and Technical Research Council of Turkey, 2012)
In this study, the karyotypes of 13 taxa of the tribe Lactuceae growing naturally in Turkey were examined. Of the species of the genus Scorzonera L. (Asteraceae), S. laciniata L. subsp. laciniata, S. cana (C.A.Mey.) Hoff ...
On suborbital graphs for the extended modular group Γ̂
(Springer, 2013)
In this paper, we show that the extended modular group ?? acts on ?? transitively and imprimitively. Then the number of orbits of ??0(N) on ?? is calculated and compared with the number of orbits of ?0(N) on ??. Especially, ...
Genetic variability of Beauveria bassiana and Metarhizium anisopliae var. anisopliae isolates obtained from the Eastern Black Sea Region of Turkey
(Scientific and Technical Research Council of Turkey, 2012)
Beauveria bassiana (Balsamo) Vuillemin and Metarhizium anisopliae var. anisopliae (Metschnikoff) Sorokin are the most common entomopathogenic fungi used in microbial control programs all over the world. Assessments of the ...
Chemical composition and antimicrobial activity of the essential oils from the aerial parts of Astragalus hamzaoglui extracted by hydrodistillation and microwave distillation
(2013)
The essential oils from the areal parts (flower, leaf and stem) of Astragalus hamzaoglui were isolated by hydrodistillation (HD) and a microwave distillation (MD) process. The composition of the volatiles was analysed by ...
