The study aimed at investigating the barriers to the effective implementation of computer studies curriculum in selected junior public secondary schools of Mwansabombwe District (MWD) in Kuapula province. The study further sought to establish the availability of ICT infrastructure and equipment...
Zambia’s economic history has, to some extent, been greatly influenced by the early 1970s energy oil crisis precipitated by the steep adjustment of the international oil prices following the Arab-Israeli war of 1972. Globally, energy is arguably one of the major determinants of economic growth....

The study area was the entire country of Zambia. Secondary hydrological and weather data used was representative of the six catchment areas of the...
Download PDF ↓An important aspect in the development of semiconducting devices for use in photovoltaic systems is the design of materials with appropriate band gaps. Electronic structure calculations based on Density Functional Theory (DFT) have been extensively used to study and to describe such properties of...
Download PDF ↓As the Internet takes an increasingly central role in our communications infrastructure, the slow convergence of routing protocols after a network failure becomes a growing problem. During failures, the forwarding paths in a network change, the forwarding tables in the routers need to be updated....

Although there are many diagnostic and detection platforms for detection of various bacteria, these often require large elaborate procedures and well trained experts to execute. The turnaround time for results can sometimes be long. The development of portable and low power devices integrated...
Download PDF ↓One of the major problems in concentrating solar radiation on the Photovoltaic (PV) module is the uneven illumination of the solar cells. The non – uniform irradiance creates hot spots on the module and increases its temperature. The high temperature results in a lower efficiency and increases...
Ternary systems comprising of poly(3-hexylthiophene)(P3HT):(6,6)-phenyl-C61 butyric acid methyl ester (PCBM) and varying amounts of squarylium dye III (SQ3) were prepared and deposited by spin coating to obtain nano-size thin films. The films produced were subsequently annealed at 140 C for 10...
Download PDF ↓Planet Earth is approximately spherical in shape, and is three dimensional. To map the Earth on a flat piece of paper, in two dimensions, a map projection must be carried out. A map projection is a mathematical technique of how to represent the Earth’s curved surface on a flat surface. In Zambia,...
