Kağıt endüstrisi atık sularından lignin ve fenol' ün perlit minerali ile giderimi
(2003)
Bu çalışmada, adsorpsiyon yöntemini kullanarak, kağıt endüstrisi atık sularında kirliliğe ve zehirliliğe neden olan fenolik ve lignin bileşiklerinin giderim oranlar ile atık suyun türbidite (bulanıklık) değerlerindeki ...
Chelating agent effect on the release of gentamicin from PEG-DA hydrogels
(2008)
In this study, controlled drug release devices of poly(ethylene glycol-diacrylate) (PEG-DA) hydrogels were prepared by free radical UV polymerization. PEG-DAmacromere was cross-linked with different percentages of ethylene ...
Urease immobilized piezoelectric quartz crystal for urea conversion
(2008)
In this study, the immobilization of the enzyme urease on the surface of the quartz crystal was reported. The layer growth on silver electrode resonator was monitored with QCM and the catalytic activity of the enzyme layer ...
Quartz crystal piezo electrode surface modification for gold nano-particles immobilization
(2007)
In this study silver electrode quartz crystal surfaces were cleaned and modified to immobilize gold nanoparticles. First, the crystal surfaces were cleaned and activated with sodium hydroxide, acetone and methanol. After ...
The removal of some inorganic compounds from paper mill efluents by the electrocoagulation method
(2004)
Bu çalışmada, elektrokoagülasyon yöntemi kullanılarak kağıt atık sularının temizlenmesi amaçlandı. Amonyum, nitrit, nitrat ve fosfatın giderimi, farklı akım yoğunluklarında, elektrot (Fe ve Al) ve elektroliz sürelerinde ...
Application of microwave–assisted digestion to trace heavy metal determination in sea sediment sample
(2008)
The main goal of this study is to develop an efficient microwave digestion method for the determination of Pb, Cu, Cr, Co and Zn elements from a sea sediment sample. Microwave acid digestion techniques were investigated ...

The phenolic compounds from Hypericum perforatum and their antimicrobial activities
(2008)
Hypericum perforatum (St. John& #8217; s wort) (H. perforatum) is a plant which has been used as a medicinal herb since ancient times and grow in Europe, West Asia and North Africa. In this work, the crude extracts of ...
Interconversion between two unrelated protein folds in the lymphotactin native state
(Natl Acad Sciences, 2008)
Proteins often have multiple functional states, which might not always be accommodated by a single fold. Lymphotactin (Ltn) adopts two distinct structures in equilibrium, one corresponding to the canonical chemokine fold ...
Identification and characterization of a glycosaminoglycan recognition element of the C chemokine lymphotactin
(Amer Soc Biochemistry Molecular Biology Inc, 2004)
Chemokine-mediated recruitment of leukocytes in vivo depends on interactions with cell surface glycosaminoglycans. Lymphotactin, the unique member of the "C" chemokine subclass, is a highly basic protein that binds heparin, ...
