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 ...
Interdependence of absorber composition and recombination mechanism in Cu(In,Ga)(Se,S)(2) heterojunction solar cells
(Amer Inst Physics, 2002)
Temperature-dependent current-voltage measurements are used to determine the dominant recombination path in thin-film heterojunction solar cells based on a variety of Cu(In,Ga)(Se,S)(2) alloys. The activation energy of ...
Critical thermal minima of Penaeus semisulcatus (Decapoda : Penaeidae) acclimated to four temperature levels
(Wiley-Blackwell, 2008)
Critical thermal minima (CTmin) and lower incipient lethal temperature (LILT) were determined for Penaeus semisulcatus juveniles at four different acclimation temperatures (14, 20, 26, and 32 Q. The effect of cooling rate ...
Design and construction of school work tables for developing countries
(Forest Products Soc, 2009)
Cyclic tests were conducted to determine the strength and durability of two types of school work tables designed for use in developing countries which were constructed with round mortise and tenon joints. The frames were ...
Ghrelin may reduce radiation-induced mucositis and anorexia in head-neck cancer
(Churchill Livingstone, 2007)
Body weight toss is common in cancer patients, and is often associated with poor prognosis, it greatly impairs quality of life (QOL). Radiation therapy (RT) is used in head and neck cancers (HNC) either as a primary treatment ...
