Zur Kenntnis der Tief- und Hochtemperaturform eines Oxidarsenats des Zinks:
Single crystals of the low (t-) and high (h-) temperature form of Z n 0Z n 3(A s 0 4)2 have been prepared by flux and by C 0 2-LASER techniques respectively. Both compounds crystal lizes monoclinic, space group C2h-P2;/n with the lattice parameters t-Z n0Z n3(A s 0 4)2: a = 9.807(3), b = 8.180(2), c = 9.967(2) A , ß = 116.53(2)°, Z = 4 and h-Z n0Z n3(A s 0 4)2: a = 9.743(3), b = 8.163(8), c = ...

متن کاملZur Kenntnis zweier Formen des Zinkorthoarsenates: a-Zn3(A s04)2 und /3-Zn3(A s04)2
Z. Naturforsch. 51 b, 333-337 (1996); eingegangen am 31. August 1995 Zinc, Arsenic, Oxide, Crystal Structure Single crystals of two forms of zinc orthoarsenate (a-Zn3(As04)2 (I) and /3-Zn3(As04)2 (II)) have been prepared by flux techniques. Both compounds crystallize monoclinically, space groups (I): Cih-P2l/c, (II): Cih-P21/n, with the lattice parameters (I): a = 6.306(2), b = 8.652(2), c = 'o...
متن کاملHypotensive, vasorelaxant and cardiodepressant activities of the ethanol extract of Sideritis raeseri spp. raeseri Boiss & Heldr.
Sideritis raeseri spp. raeseri Boiss & Heldr is a native plant from the Mediterranean region that is used due to its medicinal and culinary properties. The aim of this study was to evaluate the effects of ethanol extract of S. raeseri on the blood pressure, vascular and cardiac contractions. Arterial blood pressure was registered directly from the carotid artery in the anaesthetized rabbits. Ao...
متن کاملEvaluation des SI ; Besoins en méthodes et outils provenant de lergonomie et de lIHM
This paper concerns IS evaluation, according to two points of view: needs in adapted software processes, needs in methods and tools from software Ergonomics and Human-Computer Interaction (HCI). General needs are first underlined, as well as needs concerning the place of evaluation in software processes. Several categories of evaluation methods from software Ergonomics and Human-Computer Intera...
