The objective of this work was to investigate the effects of the impulses induced by potholes on motor vehicle structures. MATLAB computer package was used to develop a computer program to carry out the tasks. This was done with a view to make recommendations in the nature and frequency of...

There has been an accelerated use of Computer Numerical Control machine tools by developed countries over the past decade resulting in manufacturing companies becoming more competitive on the world market. However, the initial cost of these machines is prohibitive to many companies in the third...

Several 5-0-toluene-p-sulphonyl and 5-iodo derivatives of «-and 3-ribofuranoses and «-xylofuranose have been prepared in order to study their reactions with sodium hydrogen carbonate in dimethyl sulphoxide. Similar reactions are known to convert acylic primary sulphonates and iodides to aldehydes...

A numerical model for determining the size of a forced - convection solar fish dryer comprising of a drying bin (in which the fish is kept), aflat plate solar collector and a fan, has been developed. The model comprises of two sections with the first section calculating the technical parameters...

This study looked at the perceptions of environmental hazards and disasters in Zambia’s college geography education. The problem investigated by this study was that lecturers and students took what they taught and learnt respectively on the topic of ‘environmental hazards and disasters’ for...

This study investigated the prevalence and nature of mathematical difficulties among grade five pupils in selected schools of Lusaka Province. The objectives of this study were: • To establish the proportion of fifth graders that experience difficulties in mathematics in selected schools in...

Water supply management and wastewater disposal is a widespread problem, which can have significant impacts on an individual's daily life, health and the general environment. This study explored the situation of water management and wastewater disposal at the University of Zambia Great East Road...

Pumps, of varying designs, have historically been vital in fluid flow. In Zambia, typical applications could be found in domestic water supplies and industrial applications. Complete pumping units have been designed and manufactured elsewhere. The manufacture of pumps in Zambia has generally...

This study, on the relationship between self efficacy and mathematics performance among grade eleven pupils was conducted in three high schools in Lusaka urban, Lusaka province, Zambia. The study concentrated on investigating the relationship between self efficacy and mathematics performance. The...
