(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 ... -
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 ... -
Theoretical analysis and design of joints in a representative sofa frame constructed of plywood and oriented strandboard
(Forest Products Soc, 2008)Increasingly, plywood and oriented strandboard (OSB) are being used in the construction of upholstered furniture frames. There is little information available, however, concerning the strength of frames constructed with ... -
The influence of gallium on the magnetocaloric properties of Gd5Si2Ge2
(Elsevier Science Sa, 2008)Gd5Si2Ge2 was alloyed with varying amounts of Ga to study its influence on the giant magnetocaloric effect. Investigations on Gd-5(Si2-xGe2-x)Ga-2x with 2x = 0.03, 0.05 and 0.13 were carried out using X-ray powder diffraction, ... -
Effect of temperature and salinity on low thermal tolerance of Penaeus semisulcatus (Decapoda : Penaeidae)
(Wiley-Blackwell, 2008)Critical thermal minima (CTmin) and lower incipient lethal temperature (LILT) were determined for Penaeus semisulcatus juveniles at combinations of four acclimation temperatures (18, 22, 26 and 30 degrees C) and four ... -
Annual cycle of zooplankton abundance and species composition in Izmit Bay (the northeastern Marmara Sea)
(Academic Press Ltd- Elsevier Science Ltd, 2008)The monthly abundance, biomass and taxonomic composition of zooplankton of Izmit Bay (the northeastern Marmara Sea) were studied from October 2001 to September 2002. Most species within the zooplankton community displayed ... -
A novel analytical system involving hydride generation and gold-coated W-coil trapping atomic absorption spectrometry for selenium determination at ng l(-1) level
