Biosafety, biodiversity and significance of Microbial Resource Centers (MRCs) in microbiology education
(Springer, 2006)
Interest in the intrinsic behavior of microorganisms has led to the establishment of centers of expertise, known as Microbial Resource Centers (MRCs) built around specialized collections of cultures of microorganisms. Their ...
Developing students' understanding and thinking process by model construction
(Hacettepe Univ, 2007)
There is growing recognition that models play a fundamental role in the comprehension of science concepts. This paper aims at enhancing students' understanding and thinking by model construction. Seventh grade middle school ...
Immobilization of pancreatic lipase on chitin and chitosan
(Taylor & Francis Inc, 2006)
In this study, porcine pancreatic lipase (EC 3.1.1.3) was immobilized on chitin and chitosan by adsorption and subsequent crosslinking with glutaraldehyde, which was added before (conjugation) or after (crosslinking) washing ...
Synthesis, characterization, and sorption properties of silica gel-immobilized Schiff base derivative
(Academic Press Inc Elsevier Science, 2008)
Silica gel was derivatized with benzophenone 4-aminobenzoylhydrazone(BAH), a Schiff base derivative, after silanization of silica by 3-chloropropyltrimethoxysilane (CPTS) by using a reported method. Characterization of the ...
Synthesis of new azo dyes and copper(II) complexes derived from barbituric acid and 4-aminobenzoylhydrazone
(Scientific Technical Research Council Turkey-Tubitak, 2008)
Four new azo dyes, L-1, L-2, L-3, and L-4, were prepared by linking benzaldehyde p-aminobenzoylhydrazone (3) and p-hydroxybenzaldehyede p-aminobenzoylhydrazone (4) to barbiturie acid and 1,3-dimethylbarbituric acid through ...
Simulation for capacitance correction from Nyquist plot of complex impedance-voltage characteristics
(Pergamon-Elsevier Science Ltd, 2008)
The impression of series resistance on unipolar semiconductor device's capacitance-voltage spectrum is discussed by conventional impedance and admittance analysis, and it is shown that series resistance may cause large ...
Bending Strength of Screwed Corner Joints with Different Materials
(Gazi Univ, 2006)
Tests were carried out in order to determine the bending strength with compression and tension force with and without glue in addition to screws on furniture corner joints in a construction case. The specimens were prepared ...
Effects of subchronic treatment of parathion on immune potential marker enzymes of rats
(Asian Journal of Chemistry, 2008)
The effects of methyl parathion in sublethal concentration on immune potential enzymes [adenosine deaminase and myeloperoxidase] of rats was investigated under laboratory conditions. Methyl parathion (5 and 10 ppm) was ...
Determination of heavy metals (Cd, Pb) and trace elements (Cu, Zn) in sediments and fish of the Southeastern Aegean Sea (Turkey) by atomic absorption spectrometry
(Elsevier Sci Ltd, 2006)
The Bay of Gulluk in Southeastern Aegean Sea (Turkey) is very important by the potential of marine product in the Aegean Sea. There are various polluting elements in Gulluk Bay. The current situation of the bay and impact ...
Examination of the Electroanalytic Performance of Carbon Nanotube (CNT) Modified Carbon Paste Electrodes as Xanthine Biosensor Transducers
(Scientific Technical Research Council Turkey-Tubitak, 2008)
The effect of multi-walled carbon nanotube (MWCNT) and single-wall carbon nanotube (SWCNT) on carbon paste electrode (CPE) electrochemical response was examined by introducing various portions of CNT into the CPE. The ...
