INCIDENTAL RELEASE OF BITUMEN DURING OIL SHALE GRINDING AND IMPACTS ON OIL SHALE BENEFICIATION
(Estonian Academy Publishers, 2009)
The particle surface characteristics of oil shale and the changes in these characteristics with increasing fineness were determined. FTIR and electro-kinetic studies showed that the surfaces of oil shale particle were ...
Inhibition of quorum sensing-regulated behaviors by Scorzonera sandrasica
(Springer, 2007)
Many Gram-negative bacteria use N-acyl homoserine lactone signal molecules to monitor their own population density and coordinate gene regulation in a process called quorum sensing (QS). Increasing evidence implies that ...
A new boron impregnation technique of wood by vapor boron of boric acid to reduce leaching boron from wood
(Springer, 2005)
This study was designed to reveal impregnation ability and to enhance leaching resistance of boron from borate-treated wood. Vapor boron treatment was applied in cornpressed and uncompressed states at high temperatures ...
Measurement and comparison of complex impedance of silicon p-i-n photodiodes at different temperatures
(Maik Nauka/Interperiodica/Springer, 2007)
The dark alternating current (ac) parameters of BPW34 and BPW41 (Vishay-Telefunken) silicon p-i-n photodiodes arc measured and compared at different temperatures using the impedance spectroscopy technique. The impedance ...
Effect of the number of screws and screw size on moment capacity of furniture corner joints in case construction
(Forest Products Soc, 2008)
Tests were carried out in order to determine the bending moment capacity of L-type glued-screwed coner joints constructed with multiple screws. 6 sizes of screws were used for assembling the specimens. 2, 3, and 4 screws ...
Sepiolite-PAN intercalation used as Si3N4 forming precursor
(Kluwer Academic Publ, 2001)
Silicon nitride (Si3N4) formation was investigated using sepiolite and polyacrylonitrile as silicon and carbon source, respectively. It was found that purified sepiolite could readily adsorb a sufficient amount of acrylonitrile ...
Design, performance, and calibration of CMS forward calorimeter wedges
(Springer, 2008)
We report on the test beam results and calibration methods using high energy electrons, pions and muons with the CMS forward calorimeter (HF). The HF calorimeter covers a large pseudorapidity region (3 <= vertical bar eta ...
Age-related changes in tissue and plasma zinc levels: Modulation by exogenously administered melatonin
(Taylor & Francis Inc, 2008)
Melatonin (MEL) is synthesized mainly in the pineal gland and derived from 5-hydroxytryptophan (5-HTP). Zinc (Zn) is one of the most important trace elements in the body. Zn and MEL levels are changed with aging. The aim ...
