Many physical problems are studied through mathematical equations especially differential equations. For example, problems in mechanics, electricity, aerodynamics, to mention just a few, use differential equations. While it is true to say that physical sciences and tech¬nology are the two main...

Syenitic rocks in Eastern Zambia are represented by both oversaturated quartz bearing types and undersaturated nepholine-sodalite varieties.The ,Sinda syenite intrusions are oversaturated potassics which form a petrogenetically related N-S trending string of intrusions at the eastern margin of...

The purpose of this dissertation was to evaluate the effort, efficiency and performance of private water utilities to improve service delivery in Chawama Township, by Lusaka Water and Sewerage Company (LWSC). 200 household heads who were selected using systematic sampling, were interviewed in...

This study was undertaken to develop an optimum production plan for an underground mine using Renco Mine, an underground gold Mine in Zimbabwe,as a case study.A detailed structural analysis of the orebody's grade distribution has been done to establish technical parameters for production...

Tine cyanidation process for extracting precious metals (gold and silver) from the anode slimes was investigated. The recovery of these metals from cyanidation solution by adsorption on activated cai-bon has been studied. Ttiis was to assess the cyanidation and adsorption process as a potential...

All sheet metal forming processes occur after permanent plastic deformation resulting in the material properties changing and therefore it is necessary to determine the extent to which a material can further be deformed for subsequent forming operations. Traditionally, experimental trial and...

This dissertation considers the single quantum pair annihilation of positrons with bound K-shell electrons in heavy atoms. It gives numerical calculations of the total cross section. By means of the method due to Basbas et a/.14, the binding-energy effect and its contribution to SQA cross...

The literature on the mineral deposits and small-scale mining activities in Zambia has been reviewed. The present state of the industry has been described with particular reference to the supportive services given by various institutions. The way in which the research, government and mining...

The ordinary time-independent Landau problem of a charged particle moving in an external perpendicular homogeneous magnetic field and the case of when a linear potential is introduced are reviewed for motion occurring in an infinite plane, on an infinite strip and in the half-plane. The first...

Studies were carried out in the South Luangwa National Park, located in the Luangwa Valley Zambia., on the behaviour, ecology and vectorial capacity of G. brevipalpis and G. m. morsitans and G. pallidipes. The catch of G. brevipalpis was low in odour baited epsilon, NGU2G, F3 and biconical traps...
