The production of energy from fossil fuels and nuclear materials has environmental drawbacks. These drawbacks include the creation of nuclear waste and the pollution associated with fossil fuels which lead to global warming and climate change. It is apparent that alternative and sustainable...

Studies were carried out on Rusinga Island and the mainland in the Mbita Division of South Nyanza District, Kenya, from November 1987 to December 1989 to determine the distribution and die! activity patterns,population dynamics and responses of Glossina fusci pes Fusci pes Newstead 1910 to...

In this paper we will be considering two measures on sorae measure space (X, A). For general p > o we can consider the tiro norms |jf|[p,y and }|fj|p,v. We are interested in conditions on y and v that make ||f||p, y - | [f | |p,v for all f in sorae class of functions, i.e. when there exist...

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...
