On suborbital graphs and related continued fractions
(Elsevier, 2011)
In this paper, we study suborbital graphs for congruence subgroup ?0(n) of the modular group ? to have hyperbolic paths of minimal lengths. It turns out that these graphs give rise to a special continued fraction which is ...
Reduction in membrane phosphatidylglycerol content leads to daptomycin resistance in Bacillus subtilis
(2011)
Daptomycin (DAP) is a cyclic lipopeptide that disrupts the functional integrity of the cell membranes of Gram-positive bacteria in a Ca 2+-dependent manner. Here we present genetic, genomic, and phenotypic analyses of an ...
Radionuclide concentration in tea, cabbage, orange, kiwi and soil and lifetime cancer risk due to gamma radioactivity in Rize, Turkey
(Wiley, 2011)
BACKGROUND: In this study, the activity concentrations of 232Th, 238U, 40K and 137Cs were measured in tea, cabbage, orange, kiwi and soil samples collected from different stations using gamma spectrometry with a high-purity ...
Molecular identification and distribution of Anopheles maculipennis complex in the Mediterranean region of Turkey
(Elsevier, 2011)
The present study was set to identify the members of An. maculipennis complex, which includes effective malaria vectors, throughout the Mediterranean region of Turkey using the second internal transcribed spacer of ribosomal ...
Synthesis of novel triazol compounds containing isatin as potential antibacterial and antifungal agents by microwave and conventional methods
(Sage Publishing, 2011)
Microwave irradiation has been used to accelerate the conversion of isatin (1a) and 5-nitroisatin (1b) into their Schiff bases 3-[5?-aryl(alkyl)- 2?,4?-dihydro-1?,2?,4?-triazol-3?-on- 4?-yl]iminoisatin (3a-g) and ...
Chemical composition and antimicrobial activity of the essential oils from evernia prunastri (L.) ach. and evernia divaricata (L.) ach.
(Chemical Publishing Co., 2011)
In present studies, the chemical composition and antimicrobial activity of the essential oil of Evernia prunastri (L.) Ach. and Evernia divaricata (L.) Ach have been analyzed. The essential oils obtained by hydrodistillation ...
Body size and age structure of Pelophylax ridibundus populations from two different altitudes in Turkey
(Brill, 2011)
We estimated differences in body size and age structure of two populations of Pelophylax ridibundus living at different altitudes in Turkey, one from Dörtyol (6 m a.s.l.) and the other from Karagöl (1480 m a.s.l.). Their ...
Effects of selected groundwater chemical traits on a salt marsh community
(2011)
Electrical conductivity, exchangeable sodium ratio and water depth have negative impacts, whereas soil organic matter concentration has a positive impact on Black Sea salt marsh vegetation. The most saline soils were ...
Fuzzy logic controlled buck-boost DC-DC converter for solar energy-battery system
(IEEE, 2011)
In this paper, a Fuzzy Logic Controlled (FLC) buck-boost DC-DC converter for solar energy-battery systems is presented. General design of a fuzzy logic controller (FLC), based on Matlab/Simulink is performed. This design ...
New olefinic centred binuclear clamshell type phthalocyanines: Design, synthesis, structural characterisation, the stability and the change in the electron cloud at olefine-based symmetrical diphthalonitrile fragment by the combined application of UV-Vis electronic structure and theoretical methods
(Elsevier, 2011)
The olefinic centred Schiff base (3) was obtained from the condensation of substituted dialdehyde (1) with 2-amino-4-methylphenol (2) in a 1:2 ratio. The diphthalonitrile derivative (5) was prepared by the reaction of ...
