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...

Brucellosis is a neglected zoonotic disease that affects humans and animals and can lead to severe illness in humans and financial losses for households that rear livestock. In human cases, the disease presents with fever, fatigue or malaise, flu-like symptoms, weight loss, headaches and back...

Rift Valley fever (RVF) is an important viral zoonotic disease that not only affects ruminants but can cause serious morbidity and mortality in humans. In humans, symptoms range from mild flu-like to severe form such as retinal damage, meningo-encephalitis to haemorrhagic fever. From previous...

The Neonatal Intensive Care Unit (NICU) has been denoted as a place of uncertainty, fear, anxiety and sorrow as the experience of having a baby admitted to the NICUis seldom unexpected, traumatic and demanding. Previous studies have discovered that families of NICU infants often experience...
