Characterization of selected pesticide residues in sediments of the Ugandan side of Lake Victoria
(Makerere University, 2009-06)This study investigated the role of biogeochemical processes in influencing bio-availability and biodegradation of selected pesticides in Lake Victoria. Due to the hydrophobicity nature of most pesticides, sediments which ... -
Chemical structure and properties of anthocyanins from selected plant species from Uganda towards nutraceutical development
(Makerere University, 2022-05-13)Noncommunicable diseases pose national and global threat to public health and hence there is a need for appropriate intervention. Ingestion of nutraceuticals rich in anthocyanin phytochemicals is associated with reduced ... -
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 ... -
Contributions to reduced rank modelling with applications to small area estimation
(Makerere University, 2021-08)This dissertation focuses on the problem of decomposing residuals in the GMANOVAMANOVA models with rank restrictions on parameters with applications in small area estimation. Firstly, residuals in the GMANOVA-MANOVA model ... -
Delineation of petroleum plays in the Semliki Basin, Albertine Graben Western Uganda, from trap-type perspective
(Makerere University, 2019-10)Prospects evaluation in the Semliki basin demonstrated working petroleum system, but no viable targets have been discovered. This work was aimed to identify and group the prospective hydrocarbon resource areas of the basin ... -
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 ... -
Design of a water purification technology for the removal of Iron, Manganese, and Escherichia coli from ground water supply of Oruchinga Refugee Settlement Communities
(Makerere University, 2022)The present study investigated the levels of iron, manganese, and E. coli in the boreholes and shallow wells waters of the Oruchinga valley refugee camp. A multi-stage filter technology was designed for the removal of total ... -
Determination and analysis of radiofrequency intensities from digital television broadcasting transmitters in Kampala metropolitan, Uganda
(Makerere University, 2022-04-05)Digital Terrestrial Television (DTTV) broadcasting transmitters use radiofrequency electromagnetic waves to broadcast television signals to television viewers in an area of interest. The strength of a received television ... -
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 ... -
Development and performance analysis of a parabolic dish solar concentrator integrated with a heat storage block
(Makerere University, 2023-12-13)Solar irradiance received on the earth’s surface is highly intermittent. This affects the availability of solar energy for cooking especially with parabolic dish solar cookers which rely on beam solar irradiance. In this ... -
Development of a sensible heat packed bed energy storage system for medium temperature applications
(Makerere University, 2020-11-01)Utilization of solar energy can be a strategy to provide clean and cheap energy for various purposes such as cooking. Unfortunately, solar energy is intermittent and unreliable for continuous usage. As a result, it ... -
Development of a thermal energy storage system Integrated with a cooking unit.
(Makerere University, 2022-07-19)The application of thermal energy storage technology in domestic cooking is a modern clean method where heat energy is stored in sensible or latent form. To extract the stored heat energy, specialized heat transfer ... -
Development of an appropriate solar radiation model for Uganda
(Makerere University, 2006-09)Sizing of solar energy systems is necessary in order to optimize their output. This requires a database of solar radiation for locations for which the systems are being assessed. Solar radiation data is also required in ... -
