Influence of Sc.sup.3+./sup. doping on Pr.sup.3+./sup. emission in epitaxial scintillation garnet layers
Hanuš, M. ; Kučera, M. ; Nikl, Martin ; Nitsch, Karel ; Průša, Petr ; Mareš, Jiří A. ; Onderišinová, Z.
Yttrium (Y3Al5O12) and lutetium (Lu3Al5O12) aluminium garnets doped by rare earths such as Ce, Eu, Pr, are considered as very good scintillation materials. The garnets have chemical, mechanical, and radiation stability superior to most of scintillation materials and light yield is high, thus they are often used as scintillation screens.

Smooth Continuation for a Model of Unilaterally Supported Beam
Eisner, Jan ; Kučera, Milan ; Recke, L.
This note concerns a class of parameter dependent variational inequalities including a model of an elastic beam with a unilateral obstacle. A result about smooth continuation of solutions with respect to the parameter is described. Inparticular, the ends of the intervals, where the solutions touch the obstacle,depend smoothly on the parameter. Eventhough the problem is nonsmooth, .......
