(Makerere University., 2023-09-06)Lake Edward basin is a rift basin located in the extreme south of the Ugandan portion of the western arm of the East African Rift System (EARS), popularly known as the Albertine Graben. 3D basin modelling approach was ... -
Drug-resistant bacterial contamination and efficacy of selected herbal medicines sold in Kampala city, Uganda (MakIR) (Unpublished PhD Thesis) Makerere University Kampala Uganda
(Makerere University., 2023-08-19)Background: Antimicrobial resistance (AMR), is when pathogens such as bacteria evade activities of drugs to which they were once susceptible, causing treatment failure. The AMR is escalating and is among the leading causes ... -
Brain tumor origin localization via iterative methods
(Makerere University, 2023-08-15)We study the brain tumor growth with and without treatment by using the commonly used mathematical PDE models of the Reaction-diffusion type. The models describe tumor cell density change over time due to cell proliferation, ... -
Risk factors associated with schistosomiasis in school-age children around Lake Albert, Western Uganda
(Makerere University, 2022-11)Schistosomiasis remains a major public health problem in the endemic communities of Uganda. To improve schistosomiasis control strategies in Uganda, this study aimed at assessing the effects of water sources, sanitation, ... -
Mathematical methods for computing centrality measures based on powers of the adjacency matrix for large networks
(Makerere University, 2023-08-07)Network models have become essential tools in information retrieval, decision making, and general interconnected systems. Importantly, in a network, it is often of interest to locate the most important vertices, mainly by ... -
Parasitism of Psyllaephagus blitues (hymenoptera: encyrtidae) a biological control agent of the eucalyptus pest Glycapsis brimblecombei ( hemiptera : aphalaridae) in selected agro ecological zones of Uganda.
(Makerere university., 2023-02-06)Eucalyptus is important in plantation forestry in Uganda this is because of early rotation, high coppicing ability, and can be grown in most parts of the country however invasive pests like Glycaspis brimblecombei Moore ... -
Stress tensor inversion using focal mechanisms of earthquakes recorded in the Rwenzori Region, Albertine Rift System
(Makerere University, 2023-05-12)The goal of this study is to determine the regional stress tensor in the Rwenzori region using the fault plane solutions. Rwenzori region is located in Uganda and an integral part of East African Rift System. The research ... -
Hydrocarbon Generation, Migration and Accumulation Analysis in the Semliki Basin, Albertine Graben, Western Uganda
(Makerere University., 2022-11-16)Early petroleum exploration efforts in the Semliki basin discovered gas condensate with high concentration of CO2 gas in its reservoirs, setting scientific challenges to understand these accumulations. Being a frontier ... -
