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 ...
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 ...
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 ...

Isolation and characterization of mesophilic, oxalate-degrading Streptomyces from plant rhizosphere and forest soils
(Springer, 2004)
The present work was aimed at the isolation of additional new pure cultures of oxalate-degrading Streptomyces and its preliminary characterization for further work in the field of oxalate metabolism and taxonomic studies. ...
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 ...
