(Makerere University., 2024-11-06)3-D seismic and well data of the Gumry Oil Field were integrated to execute this study using petrophysical analysis, rock physics templates, and post-stack seismic inversion to characterize the reservoir potential of ... -
Characterizing phenotypic and genotypic resistance to insecticide in Anopheles gambiae s.l. from the West Nile region in Uganda
(Makerere University, 2024)In sub-Saharan Africa, Anopheles gambiae sensu lato and Anopheles funestus mosquitoes are the major vectors of Plasmodium that cause malaria; a leading cause of mortalities and morbidity in humans. In order to control ... -
Lotka-Volterra Predator-Prey Population Model with Spatial and Temporal Effects.
(Makerere University., 2024-10-25)Mathematical models have received extensive attention, and in particular, the Lotka-Volterra predator-prey population models are of great interests to mathematicians and ecologists. This has given rise to systems which ... -
Reproductive biology of Protopterus aethiopicus in Lake Bisina, Uganda and performance of Larvae under experimental diet
(Makerere University, 2024)Protopterus aethiopicus (Heckel, 1951) is an important food fish due to its meaty and taste qualities. It is an air breather and can survive desiccation of its habitat and low dissolved oxygen levels. Its population is ... -
Geochemical evaluation of source rock potential of formations penetrated by Muamba-1 well in block 5, Kwanza Basin, Angola
(Makerere University, 2024-09)This study addresses the challenges posed by unsuccessful exploration in Block 5 of the Kwanza Basin, Western Angola, and sought to evaluate source rock constraints affecting the development of petroleum potential herein. ... -
Trypanosome genetic diversity and differential gene expression profiles associated with Human African Trypanosomiasis (HAT) clinical phenotypes in Malawi
(Makerere University, 2024)Background: Clinical pathology of Rhodesian Human African trypanosomiasis (r-HAT) in sleeping sickness in endemic countries varies depending on disease foci. To gain more insight of r-HAT disease in Malawi, the current ... -
Optimal Actuator Design and Placement for a Linear Wave Equation.
(Makerere University., 2024-08-07)In this dissertation, the optimal actuator design and placement problem for a linear wave equation is studied. This problem arises in many areas of application in science and engineering, for example, in seismic inversion, ... -
Mathematical Models for the Transmission Dynamics of FowlPox Disease with Seasonality and Control Measures.
(Makerere University., 2024-08-15)Fowlpox disease poses a real threat to domestic birds, especially the chicken and turkeys in Uganda and the world, despite the tremendous efforts put in place to avert the transmission. The disease prevalence varies depending ... -
