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 = ...

Despite the existence of substantial biography, written in Hungarian in 1941, Georgius Purkircher (c. 1533-77) has never been a name to conjure with. He is known, if at all, only for a long poem on the...

Beiträge zur angewandten Wirtschaftsforschung

Firms may face nancing constraints as a result of rational behaviour of potential lenders due to asymmetric information. In this article, a theoretical model of employment adjustment is developed to derive hypotheses on the short-run impact of nancing constraints on employment at the rm level. A unique rm panel data set for German manufacturing is used to assess the empirical evidence for this ...
