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
(Pergamon-Elsevier Science Ltd, 2008)A novel analytical technique was developed where gaseous hydrogen selenide formed by sodium tetra hydrobora te reduction is transported to and trapped on a resistively heated gold-coated W-coil atom trap for in situ ... -
Determination of antimony by using tungsten trap atomic absorption spectrometry
(Pergamon-Elsevier Science Ltd, 2008)An electrically heated tungsten coil was used as a trap in the determination of antimony. The technique consists of three steps. Initially, SbH(3) is formed by hydride generation procedure; then the analyte species in vapor ... -
Volumetric evaluation of the relations among the cerebrum, cerebellum and brain stem in young subjects: a combination of stereology and magnetic resonance imaging
(Springer France, 2008)The Cavalieri estimator using a point grid is used to estimate the volume of three-dimensional structures based on two-dimensional slices of the object. The size of the components of intracranial neural structures should ... -
