Biosynthesis of silver nanoparticles using chitosan immobilized Bacillus cereus: Nanocatalytic studies
(ELSEVIER SCIENCE BV, 2013)
In this paper, the biosynthesis study of silver nanoparticles (AgNPs) using chitosan immobilized on the Bacillus cereus (Bc-C) was performed via bioreduction without any reducing agent. Transmission electron microscopy ...
The applicability of the "Sniffin' Sticks" olfactory test in a Turkish population
(INT SCIENTIFIC LITERATURE, INC, 2013)
Background: Olfactory assessment is often neglected in clinical practice, although olfactory loss can assist in diagnosis and may lead to significant morbidity. "Sniffin' Sticks" is a modern test of nasal chemosensory ...
Measurements of radon concentrations in spa waters in Amasya, Turkey
(OXFORD UNIV PRESS, 2013)
Radon concentration measurements were performed in four spas used for therapy, drinking and irrigation purposes in the Amasya basin in Turkey, during a period of time between January 2009 and May 2010. The measurements ...
A note on common fixed points for (psi, alpha, beta)-weakly contractive mappings in generalized metric spaces
(SPRINGER INTERNATIONAL PUBLISHING AG, 2013)
Very recently, Isik and Turkoglu (Fixed Point Theory Appl. 2013:131, 2013) proved a common fixed point theorem in a rectangular metric space by using three auxiliary distance functions. In this paper, we note that this ...
Teachers' Views about Science and Technology Lesson Effects on the Development of Students' Entrepreneurship Skills
(EDAM, 2013)
The purpose of this study was to determine the views of science and technology teachers about the effects of 6th, 7th and 8th grade science and technology courses on students' entrepreneurship skills. In the study, ...
Crystal structure of 4-[benzylideneamino]-3-thiophen-2-yl-methyl-4,5-dihydro-1H-[1,2,4]triazole-5-one
(MAIK NAUKA/INTERPERIODICA/SPRINGER, 2013)
The crystal structure of the title compound C14H12N4OS was determined by the X-ray diffraction method. The compound crystallizes in the triclinic space group with Z = 2. The molecule is not planar: the dihedral angle between ...
EFFECTS OF LEAF AND PLANT AGE ON SPECIFIC LEAF AREA IN DECIDUOUS TREE SPECIES QUERCUS CERRIS L. VAR. CERRIS
(BANGLADESH BOTANICAL SOC, 2013)
In Quercus cerris L. var. cerris, four diameters at breast height (BDH) groups were selected as a surrogate for approximate plant age groups to study the effects of plant and leaf age on leaf dry mass, leaf area and specific ...
INFLUENCE OF ACTIVATOR ON MEIOSIS OF TOMATO (LYCOPERSICON ESCULENTUM MILL.)
(BANGLADESH BOTANICAL SOC, 2013)
The cytogenetic effects of activator Act-2 (based in compounds of addition hydro soluble of K-vitamin group a new and specific organic metabolic activator) on meiosis of tomato (Lycopersicon esculentum Mill.) were studied. ...
An experimental and theoretical study on concomitant polymorphism of a dithiocarbonimidates derivate in a single space group
(ELSEVIER SCIENCE BV, 2013)
The title organic dithiocarbonimidates derivate crystallizes in two different polymorphic modifications. The conformational differences between the two crystalline modifications lead to differences in crystal packing and ...
