This work is an experimental study on percolation and electrical conductivity in two-dimensions with an aim of confirming some of the theoretical predictions, and measuring some of the parameters introduced in the theory. These parameters include the percolation threshold p , the critical...

Seismic refraction and geoelectrical depth soundings were employed in Lusaka District of Zambia. Another survey was conducted in Kabwe District using resistivity mapping and depth sounding techniques. The purpose of these surveys was to evaluate the effectiveness of the methods in locating...

Metal oxide thin films have been used in thin film solar cells and other solar energy applications for many years. The main concern has been to improve their physical, electrical and optical properties in order to increase their efficiency and lower their production costs. Zinc oxide doped with...

The Kariba Reservoir is one of the largest man-made lakes in the world. It was created after the impoundment of the Zambezi River at the head of the Kariba Gorge primarily to provide hydro-electric power for mining and industrial development in the then Federation of Rhodesia and Nyasaland (which...

Silicon-based microelectronic technology is approaching its performance limits due to the rapid downscaling of electronic devices to ever smaller dimensions. Germanium, with its high electron and hole mobility, high carrier injection velocity, very low carrier free-out temperature, etc. is...

This dissertation describes the natural resource of a part of Serenje district known as Kamena. It is based on a reconnaissance survey carried out between August and October 1979 and January I98O.The Method of study was the landscape approach to land classification. The basis of such a study is...

Human-Wildlife Conflict (HWC) has become a serious threat to the survival of many endangered species in the world. The sighted examples from different countries such as Kenya, Zimbabwe, Zanzibar, Namibia, China and Peru demonstrate the severity of the conflict and suggest that greater in depth...
