When a modulated beam of 1ight impinges on a solid, elastic waves are produced as a result o-f the surface motion due to thermal expansion. In semiconductors, in addition to this thermal expansion effect, there is also mechanical strain induced in the material due to the photogeneration of excess...

A mass balance technique was used to investigate the hydrogeochemistry of the Kafixe river as it crosses the Copperbelt mining area between Raglans farm and Machiya feiTy. Tlie study is done by examining the mass flow-rates often chemical parameters, namely: total dissolved solids, total...
