Adsorption studies on the treatment of textile dyeing effluent by activated carbon prepared from olive stone by ZnCl2 activation
(Wiley, 2007)
This study aimed to investigate the removal of a reactive dye from aqueous solution by adsorption. Activated carbon prepared from olive stone, an agricultural solid by-product, was used as adsorbent. Different amounts of ...
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 ...
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 ...
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 ...
Thermo-morphological properties of the smectic C* mesophase in new chiral salicyaldimine liquid crystals
(Wiley-V C H Verlag Gmbh, 2008)
Specific textures and their temperature transformations in large temperature interval for the chiral smectic C* mesophase of new liquid crystalline materials, synthesized by our group, have been investigated in detail. ...
