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 research work was to provide a locally produced electric motor to drive the UNZA pump.The work was carried out by using the UNZA pump parameters and electric motor material from published works on the electric motor design and manufacture and real experience from examining electric motors in...

A first-order, consecutive, two-stage reaction model for the reduction of cr2o3 from slag was developed. The model was applied to the results obtained by studying the effect of various parameters on the rate of reduction of cr2o3 from a CaO-SiO2-Al2o3 slag, by carbon dissolved in molten iron, at...

Water hyacinth is, after eutrophication, the largest threat to waterways, lakes and dams throughout Africa. The aim of this study was to develop a procedure for monitoring the spread of water hyacinth on Lake Kariba using Remote Sensing and Geographic information System. The spread of water...

Recent developments in the design of variable-speed drives have been aimed at the control of a standard squirrel cage induction motor because of its many attractive features including robustness, reliability and low maintenance requirements. This dissertation demonstrates the design of a drive...

This research focused on solving the problems of application access from multiple file servers in a Novell network that caters for a large user community. The application access technique discussed in this dissertation is a step towards creating a computer network system, called a Virtual Machine...

This dissertation describes an investigation carried out at Baluba Mine to assess the quality of rock mass and support requirements in haulage drives developed in the -footwall quartzite -Formations. The rock mass o-F the -Footwall Formation is geotechnicallv quantified using the Modi-Fied Basic...

Procurement of consultants and contractors in the public construction sector is regulated in most countries. In Zambia, all public procurement is regulated by the Zambia National Tender Board Act No. 30 of 1982. Various procurement methods are used for the selection of consultants and contractors...

The poor management of wastewater causes loss of environmental quality. Biomethanation, a biogas-producing technique, as an attractive solution to the problem, was investigated. Biogas, a greenhouse gas, is a mixture of methane and carbon dioxide. While carbon dioxide is returned into the...

Combustion Efficiency Improvement in a Rotary Furnace using a Post Combustion Chamber. Luwaya Edwin. Department of Mechanical Engineering, University of Zambia.Geometric parameters, of a rotary furnace, necessary for the improvement of combustion efficiency are analysed using Computational Fluid...
