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...

Since the 1980s, mathematics educators around the world have accepted the view that to develop numeracy effectively, young children need initially to use strategies for mental calculation rather than to memorise textbook procedures. The term mental calculation refers to informal, often untaught...

Wetland processes are strongly influenced by hydrologic factors such as precipitation, surface runoff, and flooding dynamics. Anthropogenic disturbances to flooding regimes can thus substantially alter wetland habitat and biogeochemistry. The Kafue Flats, a large floodplain (-6,500 Km^) along the...

Lusaka sits on a limestone rock formation which makes recharge as well as pollution of groundwater very easy due to the presence of channels created by solution weathering. Informal/unplanned settlements where waste disposal facilities are non-existent are potential groundwater contamination...

The purpose of the study was to investigate and compare the performance in mathematics of girls from basic and community schools. The study sought the views of teachers on factors perceived to affect girls' performance in mathematics. Teachers also expressed their views through a questionnaire...

In Zambia, currently, the graduate teachers for high schools (Grades 10 to 12) are trained at the University of Zambia. However, it has been observed that most of the high schools do not have adequate numbers of university graduate teachers. In the absence of sufficient graduate teachers to teach...

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...

There are wide gaps in empirical and perceptual baseline data and information on obtaining knowledge, attitudes and practices with respect to Indoor Residual Spraying (IRS).The main objective of this study was to assess the levels of Knowledge, Attitude and Practice that Linda residents have...

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...
