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 ...
The CMS experiment at the CERN LHC
(Iop Publishing Ltd, 2008)
The Compact Muon Solenoid (CMS) detector is described. The detector operates at the Large Hadron Collider (LHC) at CERN. It was conceived to study proton-proton (and lead-lead) collisions at a centre-of-mass energy of 14 ...
Adsorption of Cd(II) ions from aqueous solutions using activated carbon prepared from olive stone by ZnCl2 activation
(Elsevier Sci Ltd, 2008)
This study is aimed to remove Cd(II) ions from aqueous solutions by adsorption. As adsorbent, activated carbon prepared from olive stone, an agricultural solid by-product was used. Different activating agent (ZnCl2) amounts ...
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 ...
Silicon improves salinity tolerance in wheat plants
(Pergamon-Elsevier Science Ltd, 2008)
Durum wheat (Triticum durum cv. Gediz-75) and bread wheat (Triticum aestivum cv. lzmir-85) were grown in a complete nutrient solution in a growth room to investigate effect of silicone supplied to the nutrient solution on ...
The double Gaussian distribution of barrier heights in Al/TiO2/p-Si (metal-insulator-semiconductor) structures at low temperatures
(Amer Inst Physics, 2008)
The current-voltage (I-V) characteristics of Al/TiO2/p-Si metal-insulator-semiconductor (MIS) structures have been investigated in the temperature range of 80-300 K. An abnormal decrease in the zero bias barrier height ...
Evaluation of the antioxidant activity of four edible mushrooms from the Central Anatolia, Eskisehir-Turkey: Lactarius deterrimus, Suillus collitinus, Boletus edulis, Xerocomus chrysenteron
(Elsevier Sci Ltd, 2008)
The methanolic extracts of Lactarills deterrimus, Suillus collitinus, Boletits edidis, Xcroconius chrysenteron were analyzed for their antioxidant activities in different test systems namely beta-carotene/linoleic acid, ...
Studies on the antioxidant activity of the essential oil and methanol extract of Marrubium globosum subsp globosum (lamiaceae) by three different chemical assays
(Elsevier Sci Ltd, 2008)
This study is designed to examine the chemical composition and in vitro antioxidant activity of the essential oil and sub-fractions of the methanol extract of Marrubium globosum subsp. globosum. The GC and GC-MS analysis ...
The influence of series resistance and interface states on intersecting behavior of I-V characteristics of Al/TiO2/p-Si (MIS) structures at low temperatures
(Iop Publishing Ltd, 2008)
In this study, we have investigated the intersection behavior of the forward bias current-voltage (I-V) characteristics of the Al/TiO2/p-Si (MIS) structures in the temperature range of 100 300 K. The intersection behavior ...
