Sustainable hydropower development provides a reliable and stable power source that is economical and environmentally friendly. However, its investment capital is huge and unbearable to third-world countries. Hence the requirement of an alternative power source that is manageable. Zambia’s main...

The seasonal interactions among rivers, floodplains, vegetation and anthropogenic activities result in highly dynamic systems, which tend to exhibit distinctly different biogeochemical patterns throughout the wet and dry seasons. An assessment and characterization of the spatial-temporal...

Mine tailings are a significant source of heavy metal contamination for soils in their proximity. In Zambia’s Copperbelt Province, historical and current mining operations have resulted in large outputs of tailings. Food crops grown on contaminated soils may be a conduit for transfer of heavy...

The Chunga landfill located in the northern part of Lusaka city receives on a daily basis approximately 500 tonnes of comingled waste comprising mostly municipal solid waste (MSW). The MSW has being accumulating over the years within the limited space at the landfill without being recycled....

Human exposure to Lead (Pb) through the ingestion of contaminated groundwater with Pb has been associated with countless health effects. The current study aimed to determine the Pb levels in groundwater and assess the associated human health risks of exposure to Pb through the consumption of...

The agricultural sector in most developing countries encounters a lot of post-harvest losses due to a lack of appropriate drying and storage facilities for preservation. Though many drying technologies have been developed, there is an increasing demand for automation in drying. Concerning this...

In an effort to mitigate post-harvest losses (PHL) of agricultural products from farmers and the markets, greenhouse solar dryers (GSD) have been extensively employed by various stakeholders. The operation of these conventional GSD is though allowing cool or cold ambient air to enter them during...

The purpose of the study was to assess the effect of pupil-teacher ratio on the quality of teaching and learning process of mathematics in selected public secondary schools of Lusaka district. Four specific research objectives which guided the study were; to determine the proportion of pupils in...

In Kabwe, contamination resulting from lead (Pb), Zinc (Zn) and Cadmium (Cd) has led to high concentration of the heavy metals in the soils. These contaminations cause a serious threat to the food chain, mostly through the uptake of these metals by crops such as maize. This study was conducted to...

This Dissertation investigates the effect of Denial-of-Service (DoS) attacks in Broadband- Wi-Fi networks involving public sector networks. Over the recent past, Wireless communications have become increasingly popular in our everyday life and the world has become increasingly mobile. Traditional...
