Estimation of Radiological Effects and Modeling Radionuclide Transfer to Milk and Fish in Kisoro, South-western Uganda
(Makerere University, 2024-04-17)Exposure to natural radiation energy (ionozing radiation) is one of the primary causes of radiation ailments like cancer. Radioactivity is widely spread in the earth’s environment and it exists in various geological ... -
Oil production optimization of the Norne Field E-Segment, Norway using Eclipse 100 Simulation Model
(Makerere university, 2024)The Norne field is located 80 km north of the Heidrun field in the Norwegian Sea. The Norne Field consists of two separate oil compartments, the Norne Main Structure (Norne C, D and E-Segment) and the Northeast Segment ... -
Computing the Artin component using Reconstruction Algebras.
(Makerere University, 2024-03-27)This thesis studies noncommutative resolutions of non-Gorenstein singularities and uses them to construct classical deformation spaces. In the first part, it recovers the Artin component of the deformation space of a cyclic ... -
Dynamics of soil-transmitted helminths under mass drug administration among school children in Kumi Municipality, Eastern Uganda
(Makerere University, 2023-09)Soil-transmitted helminthiases (STH) are neglected tropical diseases of public health significance globally, WHO recommended periodic mass drug administration (MDA) in endemic areas. In 2003, Uganda initiated MDA but ... -
