Attempts to develop Threshold Limit Values together with the correlation between results of various sampling instruments are described. The main objectives of the investigations were: to establish the relationship between dust exposure and the development of pneumoconiosis, to study the effect of...

This dissertation examines effects of inadequate water supply on the health of Zambia Compound Community in Kafue District. Both Secondary and Primary sources of information have been used. Secondary sources used were from books, the internet, journals and news papers. The primary source used was...

Current densities from 40O Am to 1000 Am were used to investigate the electrowinning of cobalt from sulfate solutiaiie. The cell used was a cylindrical beaker of 1000 ml capacity. Two lead anodes and one stainless steel cathode were used as - electrodes. The cathode was prepared electrolytically...

The erosion of Tuyeres in Refining has been studied in a Physical Model to establish the dependence upon injection conditions such as gas momentum and orifice profile.The erosion phenomena in terms of Mass transfer-mechanisms has also been studied.A coefficient of Mass transfer kc< , has been...

The introduction of antiretroviral therapy has transformed HIV care and lead to significant reduction in morbidity and mortality worldwide. In resource poor setting like Zambia, HIV-infected children often start treatment with advanced disease stage against a background of a high burden of...

_ Let * be a root system in a £-dimensional real Euclidean space V with Weyl group W( £), and let W+{<f) denote its rotation subgroup. In [173 » the projective representations of the rotation subgroup W ( 9) have been determined from those of W( $) for each root system $. This is done by...
