The continued pollution from the mining activities in Zambia both legacy and current operations is associated with the weak and unclear existing environmental legislation coupled with poor institutional arrangement of enforcement and monitoring. Implementing policies that are weak and not in line...

In general, the study focuses on Evaluation of the Effectiveness and Efficiency of Compression and Decompression of IP Packets in a Wireless Local Area Network (WLAN). IP Packet Compression is the process of reducing the packet size before transmitting data in a Wireless Local Area Network...

A Wireless sensor network (WSN) is a fast-developing technology which can monitor, calculate, and communicate wirelessly thereby finding it’s place in areas such as defence, home automation, medical care and environmental sciences which demands better security, throughput, energy efficiency and...

Finite mixture models are an important tool in modelling the distribution of a wide class of statistical problems. Mathematically, a g−component finite mixture model of multivariate t-distributions is specified by a convex combination (mixture distribution) of g multivariate t-distributions,...

The university of Zambia’s electricity provides power to operate campus infrastructure such as hostels, lecture rooms, library etc. While telecommunication utilities provide telephone, intranet and internet services. The power and communication utilities are supplied by underground cables....

Water is an essential product for human survival, which all age groups consume and access to safe drinking water is essential to health. Safe drinking water implies that the water does not represent any significant risk to health over a lifetime of consumption, including different sensitivities...

In any company, the planning and scheduling process is unavoidable. This research investigated its effects in the electrical section of Anvil Mining Congo SA. In this company, the focus of planning and scheduling, particularly on equipment, is on preventative maintenance rather than actions such...

Lead (Pb) contamination in the vicinity of lead mines and smelters affects both humans and animals. Chronic exposure to Pb via dietary intake of animal products such as milk from contaminated areas poses a health risk to consumers. Therefore, the aim of the current study was to evaluate the human...

Kitwe’s water sector is quite peculiar since historically, part of the city’s water was supplied by the mines almost for free and the other part was provided for by the local authority. Nkana Water and Sewerage Company (NWSC) is the commercial utility company that provides water in the city. It...

Natural-convection solar tunnel dryers capable of achieving greater drying rates when drying products. The increased temperature decreases the relative humidity of the air, thereby allowing the air to more efficiently dry the product. However, it is necessary to provide an appropriate solar air...
