Abstract: A baseball practice system for training one in pitching, throwing, fielding, catching, and batting. The practice system is portable and collapsible having a removable pitching component on one side and a batting and netting on the other side. The pitching component has a strike-zone opening and one or more pockets in a catch sack in back of the strike-zone opening. The netting is of an elastic material suited to rebound a ball thrown on the netting for the purpose of practicing throwing, catching, and fielding. A ball component, attached to elastic cords, is suspended outward and downward from a forward extending member adjacent to the top of the baseball practice system. An adjustment and locking member adjacent to the rear of the forward extending member adjustably secures in place an upper cord which is attached to a ball.

Abstract: New oxide phosphors based on gallium-indium oxide for electroluminescent materials. Bright red emission has been obtained using Ga2-x-yInxEuyO3 wherein x spans the range 0.1 to 0.4 and y spans the range in which it is soluble in the phosphor.
