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 ... -
Geomechanical modelling of subsurface formations in Palouch Oil Field, Melut Basin (South Sudan)
(Makerere University, 2022-10-25)The geomechanical issues which are related to mechanical properties of rocks and stress regimes in the area are one of the major causes of non-productive time (NPT) in oil and gas operations. In Palouch field area, this ... -
Fault seal analysis of the Lake Edward Basin South Western Uganda
(Makerere University, 2022-12)Fault seal analysis was carried out in the Lake Edward basin that lies within the Albertine graben between Uganda and the Democratic Republic of Congo. This work was aimed at assessing the fault seal potential of the faults ... -
Phytochemistry, anti-mycobacterial activity, and acute toxicity of selected plant species used for the treatment of Tuberculosis in Uganda
(Makerere University, 2023-01-27)Tuberculosis (TB) is one of the leading causes of death globally, and the rise in drug-resis-tant forms of TB has become a significant threat. Subsequently, it is crucial to explore new, effective and safe anti-TB agents. ... -
Phytochemical profiling, optimization of extraction and application of natural dyes from selected indigenous plants in Uganda
(Makerere University, 2023-01-30)Globally, textile dyeing with natural dyes (NatD) reduced tremendously with the introduction of synthetic dyes in the mid 19th Century. Later studies reported that the use of synthetic dyes is not eco-safe and cause human ... -
Delineation of the Cenozoic Petroleum plays in the Main Pass area, North Eastern Gulf of Mexico, United States of America
(Makerere University, 2023-02)This study was undertaken in the Main Pass area, north eastern Gulf of Mexico Basin with the aim of delineating the Cenozoic petroleum plays. The study involved the grouping of the structural and stratigraphic traps into ... -
Structural properties of zeolites and their application in the removal of selected heavy metals from wastewater
(Makerere University, 2023-01)The increasing industrialization in Uganda has resulted into discharge of partially treated effluents into the environment. These effluents are characterized with a number of pollutants including but not limited to toxic ... -
Characterisation of optical parameters of zink sulphide and silver metal film coated on glass at different deposition angles
(Makerere University, 2023-02-01)The greatest challenge of smart window technologies is the regulation of heat accumulation indoors through fenestration and at the same time have a good visibility. Therefore, the spectral characteristics of thermally ... -
Development and assessment of a cooking unit integrated with solar thermal energy storage system
(Makerere University, 2022-12-07)The thermal performance of a newly developed cooking unit integrated with a thermal energy storage (TES) system suitable for solar thermal applications has been tested and analysed. The experimental set-up consisted of ... -
Optical and electrical properties of thermally deposited aluminium thin films
(Makerere University, 2023-01)Thin film coatings can be applied to windows in buildings for solar control and energy-saving purposes. By regulating the solar radiation entering through windows in spectrally selective manner, it is possible to save ... -
A Solution to an Exterior Bernoulli Free Boundary problem using the Constitutive Error Cost Functional.
(Makerere University., 2023-01-20)A shape optimisation problem involves finding the minimum of the cost functional over an admissible domain. the cost functional is stated in form of an integral over a domain or its boundary, where the integrand depends ... -
