Forward and reverse current-voltage-temperature characteristics of a typical BPW34 photodiode
(Pergamon-Elsevier Science Ltd, 2006)
The dark forward and reverse current-voltage characteristics of a typical BPW34 silicon photodiode have been investigated in the temperature range 80-300 K. We propose that tunnelling enhanced recombination at or close to ...
The effects of calcium sulphate on growth, membrane stability and nutrient uptake of tomato plants grown under salt stress
(Pergamon-Elsevier Science Ltd, 2007)
A pot experiment was carried out with tomato (Lycopersicon esculentum Mill.) cv. "Target F1" in a mixture of peat, perlite, and sand (1:1: 1) to investigate the effects of supplementary calcium sulphate on plants grown at ...
Synthesis and spectroscopic properties of new azo-dyes and azo-metal complexes derived from barbituric acid and aminoquinoline
(Elsevier Sci Ltd, 2007)
Two new azo-dyes, 5-(quinoly-8-azo)pyrimidine-2,4,6-trione (L-1) and 5-(quinoly-8-azo)-1,3-dimethylpyrimidine-2,4,6-trione (L-2) were prepared by linking 8-aminoquinoline to barbituric acid and 1,3-dimethylbarbituric acid ...
Relation between intracranial volume and the surface area of the foramen magnum
(Lippincott Williams & Wilkins, 2006)
Several investigators have estimated the intracranial volume (ICV) in the past which indirectly reflects the brain volume. Most of these studies have been made on the dry skulls using linear dimensions, packing methods or ...
Effects of subacute treatment of ethylene glycol on serum marker enzymes and erythrocyte and tissue antioxidant defense systems and lipid peroxidation in rats
(Elsevier Ireland Ltd, 2007)
The present study was aimed to investigate the effects of ethylene glycol (EG) on serum marker enzymes, antioxidant defense systems and lipid peroxidation concentration (malondialdehyde = MDA) in various tissues of rats ...
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 ...
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 ...
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 ...
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 ...
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 ...
