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 ...
Does Liriomyza cicerina affect the yield of chickpeas (Cicer arietinum)?
(Springer, 2007)
Liriomyza cicerina (Rondani, 1875) (Diptera: Agromyzidae) is an important pest on chickpea (Cicer arietinum L.) in some regions of Turkey. The objective of this study was to determine whether the populations of L. cicerina ...
Chemical characteristics of rain water at an urban site of south western Turkey
(Springer, 2006)
In this study, chemical composition of the rain water in Mugla was investigated from February to April 2002. Rain water samples were obtained from Mugla, a small city in south western Turkey. The Yatagan Power Plant is ...
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 ...
