Atmospheric concentration of selected trace gases over Uganda
(Makerere University, 2019)The atmospheric concentration of the trace gases of CO2, CH4, NO2 and SO2 over Uganda was obtained at the stations of Makerere, Mukono, Lira, Tororo and Kasese. Data used in this study was retrieved from the Ozone ... -
An Automatic Electronic Photovoltaic Heating System for Charging Thermal Energy Storage Tank
(2023-01-03)Power generated by Photovoltaic modules can be directly used for heating. However, due to the intermittent nature of solar irradiance, such a PV heating system requires a controller which can automatically select the ... -
Bio-efficacy of insecticides used for vector control in Busia and Tororo districts, Eastern Uganda
(Makerere University, 2022-02-14)High malaria transmission rates in Sub-Saharan Africa (SSA) are attributed to the continuous presence of effective and competent Plasmodium vectors, Anopheles gambiae complex and the Anopheles funestus group. These vectors ... -
Bio-oil production from water hyacinth by hydrothermal liquefaction process using iron oxide-based nanocomposites as catalysts
(Makerere University, 2023-01-09)The iron oxide nanocatalyst and iron oxide/nickel oxide nanocomposite were synthesized by the co-precipitation method and used in the hydrothermal liquefaction (HTL) of water hyacinth. The composition and structural ... -
Bio-physical suitability of saline crater lakes of Western Uganda for artemia production
(2019)Despite Artemia being the most widely used live feed for successful larval weaning and rearing, unreliable quality, not being readily available and expensive especially to small farmers hinders its use. This study explored ... -
Biogeographical examination of the butterfly fauna in selected West Albertine Rift Forests
(Makerere University, 2009-09)This study was conducted with the main aim of evaluating the factors that may influence butterfly species richness and distribution (i.e. forest size, altitude, forest disturbance, average rainfall, temperature and distance ... -
Biokinetics and modelling of pollutant accumulation in Cat fish (Clarius casonii) and Silver fish (Rasteneobola argentea) from selected aquatic ecosystems in Uganda
(Makerere University, 2019-12)Concentrations of DDT and its residues and heavy metals (Zn, Cu, Pb and Cd) were determined in Clarius casonii collected from Nakivubo and Lubigi wetlands and Rasteneobola argentea from lakes Victoria and Kyoga. Measured ... -
Biomass and hydropower potential and demand in the Uganda Albertine Rift Region
(Makerere University, 2006-08)This study assessed the hydropower potential in the Albertine Rift Region and suggested electricity as an alternative to reduce the pressure on biomass. Hydrological and topographical conditions of the region were analyzed ... -
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, ... -
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 ... -
Characterisation of resistant starch in selected banana cultivars
(Makerere University, 2022-12-14)In the green stage of the banana, starch accumulates most of which is resistant to degradation by amylases. The resistant starch is utilised in industry for development of nutraceuticals and as a functional food for ... -
Characterization of anthocyanins from selected plant species in Uganda
(Makerere University, 2008-10)Different plant species were collected from different parts of the country in the period 2003 to 2007. Extraction of the plant material collected was done using methanol acidified with various amounts of trifluoroacetic ... -
Characterization of reservoir properties for the Kisegi Formation in Semliki Basin, Albertine Graben, Western Uganda using rock physics diagnostics
(Makerere University, 2019-11)The quality of a reservoir rock is a fundamental input in evaluating its productivity during exploration and appraisal. Therefore, attempts to characterize the formation using rock physics diagnostic ... -

(Makerere University, 2019-11-22)The quality of a reservoir rock is a fundamental input in evaluating its productivity during exploration and appraisal. Therefore, attempts to characterize the formation using rock physics diagonostic ... -
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 ... -
