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 ...
Coverage-based, prioritized testing using neural network clustering
(Springer-Verlag Berlin, 2006)
Graph-based algorithms are commonly used to automatically generate test cases for coverage-oriented testing of software systems. Because of time and cost constraints, the entire set of test cases generated by those algorithms ...
Sources and distribution of trace metals in the Saricay Stream basin of southwestern Turkey
(Springer, 2007)
Seasonal variation of the concentrations of trace metals ( Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn) were measured by ICP-AES in the water and sediment from the Saricay Stream, Geyik Dam and OrtakoyWell in the same basin. ...
Reproductive biology of the Patagonian bobtail squid, Semirossia patagonica (Sepiolidae : Rossiinae) in the south-west Atlantic
(Cambridge Univ Press, 2008)
A total of 104 Semirossia patagonica were collected all over the Patagonian shed bet ween the depths of 47 and 295 m. Mature female size varied from 10 to 35 mm ML, mature male size was 16-32 mm. Potential fecundity ranged ...
4-(octyloxy)-N-(4-hexylphenyl)-2-hydroxybenzalimine thermotropic compound: Morphologic, mesomorphic, thermotropic, thermooptical and thermodynamical properties
(World Scientific Publ Co Pte Ltd, 2008)
In this work, the mesomorphic, morphologic, thermotropic, thermooptical, and thermodynamical properties of 4-(octyloxy)-N-(4-hexylphenyl)-2-hydroxybenzalimine thermotropic liquid crystalline compound, which was synthesized ...
Twinned EPR spectra of Fe3+ centers in ternary layered TlGaS2 crystal
(Pergamon-Elsevier Science Ltd, 2006)
TIGaS2, single crystal doped by paramagnetic Fe3+ structure of EPR spectra of paramagnetic Fe3+ ions was observed. The spectra reveal a nearly orthorhombic symmetry of the crystal field (CF) on the Fe3+ ions. Two groups ...
Chemical composition effects onto antimicrobial and antioxidant activities of propolis collected from different regions of Turkey
(Springer, 2006)
Chrysin, apigenin, flavonoids, flavanones, naringenin, ethyl oleate, 3-4-dimethoxy-cinnamic acid and 9-octadecenoic acid were the predominant components of propolis samples collected from different regions of Turkey. The ...
EPR study of the structural phase transitions in chromium doped thallium indium disulphide
(Elsevier Science Bv, 2003)
The results of low-temperature electron paramagnetic resonance (EPR) investigations of Cr3+ doped TlInS2 single crystals in the temperature range 5-300K are presented. Remarkable temperature dependences of the linewidth ...
Numerical simulation of heat conduction for the growth of anisotropic layered GaSe crystals
(Wiley-V C H Verlag Gmbh, 2004)
In this report, we present the usage of a second rank cylindrical conductivity tensor which we derived to simulate the crystal growth processes of a layered compound GaSe in a cylindrical enclosure by directional solidification. ...
