This study aimed to determine the maximum likelihood (ML) estimates for the Gamma and Exponential distributions under conditions of left-truncated and right-censored data, employing the Expectation-Maximisation (EM) algorithm. Additionally, it sought to compare the performance of the EM algorithm...

Spices refer to dried parts of plants used in food to enhance flavor, add color and make food more acceptable. As a result spices are widely used in the food industry where they may carry a large number of bacteria and mold that could contaminate the food. The objective of this study was to...

The objective of the study was to assess the regeneration of Miombo woodlands after shifting cultivation in Chibombo and Rufunsa districts in comparison to undisturbed woodland. The study analysed different descriptors that characterize the woodland including: species composition, diversity,...

There is a significant gap in research on occupational health and safety in Africa. This study addresses this need by investigating the potential of District Health Information Software 2 (DHIS2) to develop health information systems that cater specifically to the requirements of occupational...

This dissertation is devoted to the investigation of the optical properties of two topological insulators, Bismuth Selenide (Bi2Se3) and Antimony Telluride (Sb2Te3), by optical spectroscopy reflection measurements in a wide frequency range (500 – 40000 cm−1 ) and temperature (13 to 300 K) ....

The fungus Colletotrichum lindemuthianum which causes anthracnose disease in common bean (Phaseolus vulgaris L.) has a high genetic variability that requires deployment of loci with resistance to a wide range of C. lindemuthianum races. Most of the loci have been sourced from the Middle American...

In this dissertation we obtain quasi-deformations of the special linear Lie algebra of degree 2 over a eld F, abbreviated sl2(F). We take F to be a eld of characteristic zero. Our approach involves obtaining and deforming a linear operator representation of sl2(F) using-twisted derivations (with...

Community rainwater harvesting (RWH) systems are seen as an instrument in increasing resilience in recurring droughts and enhancing food security in dry lands of Zambia. Harvested rainwater can be used for agriculture or water supply for households and other domestic uses. This study investigated...

Endocrine disrupting compounds (EDCs) are receiving increased attention in the environment due to their link to lifestyles diseases like hypertension, heart disease, type 2 diabetes and some cancers. This research aimed at assessing the presence and quantities of heavy metals and organic EDCs in...

Contagious bovine pleuropneumonia (CBPP) is a highly contagious and severe infectious disease of cattle that is listed as a notifiable disease by the World Organisation for Animal Health (WOAH). CBPP is caused by Mycoplasma mycoides subspecies mycoides small colony, which can lead to severe...
