Abstract Alkalimetalldihydrogenantimonide [M(L) x SbH 2 ], kurz: Alkalimetallantimonide (M=Li, Na, K, Rb, Cs; 1 : L=pmdta; L=Kronenether), wurden aus Stiban und n ‐Butyllithium, M(hmds) (hmds=Hexamethyldisilazan) bzw. MO t Bu hergestellt. Wir haben einen allgemein anwendbaren Syntheseweg für diese Verbindungen entwickelt die erhaltenen auf ihre Stabilität in Abhängigkeit vom verwendeten Alkalim...

Web-Based Assessment (WBA) System for K-12 needs to support the educational assessment according to the process-oriented learning and instruction. Usability issues of the Web-Based Assessment (WBA) System for K-12 refer to how to make questions efficiently, and how to control the access to the final Html test files from unauthorized people. In this paper, we study the usability issues of the an...

Biological effects due to RF whole-body exposure can be caused by core temperature rise. According to safety guidelines, therefore, whole-body averaged specific absorption rate (WBA-SAR) is being used as a metric for human protection. The threshold level causing thermal effects was determined based on animal experimental results. In order to investigate the relationship between WBA-SAR and core...
