The integrity loss of physicomechanical properties of building stones when subjected to recurrent cycles of freeze-thaw (F-T) process
(Springer, 2006)
In this study, a total of nearly 900 samples were obtained from 7 different rock types, also recognised as marbles of sedimentary and metamorphic origin and commercially used in the building of various monuments, art works ...
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 ...
Authors' Reply to Discussion by R. Goktan on "ISRM Suggested Method for determining the Shore Hardness value for rocks" by R. Altindag, A. Guney, International Journal of Rock Mechanics and Mining Sciences, 2006; 43 : 19-22
(Pergamon-Elsevier Science Ltd, 2006)
The authors appreciate the Discussion comments by Dr. Göktan and his interest in the new ISRM Suggested Method. As is known, the Shore Hardness (SH), as one of the physical properties of rocks, is widely employed to describe ...
