Les tensions interfaciaies eau-alcanes ont ete etudiees sur 6 isomeres d'hexadecylbenzenesulfonates de sodium :[math]vis a vis de quatre alcanes : octane, decane, undecane et hexadecane, en presence de NaCI. Les tensions observees (5 mN/m a 3.10-3 mN/m) sont fonction de la longueur de chaine des alcanes, de la structure des tensioactifs et de la ...

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1972
Abstract 1. 1. Glycine was the most concentrated free amino acid (FAA) in polyps of Aurelia and Chrysaora . 2. 2. Total FAA concentrations were linearly related to salinity in polyps starved for 48 hr. 3. 3. FAA data from field Chrysaora polyps indicate that quality and quantity of food and elapsed time since feeding greatly alter ...

Salinite et Histoire de l'Irak pre-islamique
Journal of the Economic and Social History of the Orient, 1990Discussion a propos de la these du determinisme pedologique, a savoir la responsabilite historique de la salinisation dans la chute des civilisations de la Mesopotamie, et plus particulierement de la civilisation de Sumer et discussion du probleme de la salinite des terres dans l'agronomie de l'Irak pre ...

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology
Triphenyltin (TPT) is an organotin compound frequently detected in coastal estuaries, yet studies on TPT's effects in regions with significant salinity fluctuations, such as coastal estuaries, are currently limited. To investigate the toxic effects of TPT under different salinity conditions, this study focused on marine medaka (Oryzias melastigma ...

R�ponse d'une communaut� de diatom�es de glace � un gradient de salinit� (baie d'Hudson)
Marine Biology, 1983Sea ice offers a physical support to the growth of microalgae (epontic community). Almost all the studies on ice microflora in the Arctic and the Antarctic have been performed in waters of high salinities, and they generally reported a very high standing crop.

Abstract Growth, food conversion, and body composition of sea bass fingerlings, Dicentrarchus labrax, exposed to different temperatures (15 and 22°C) and salinities (6, 11, 24 and 37‰) were studied. Temperature was found to have the more significant influence on these parameters.

Resume Les palmeraies nord-africaines sont menacees par le bayound, fusariose vasculaire du palmier dattier. Une partie de ces palmeraies, notamment a l'est de l'Algerie, est caracterisee par des sols a saliniteelevee. Nos travaux anterieurs ont permis de montrer que la salinite induit une resistance de ces sols a la fusariose vasculaire.
