Supported silver and copper catalysts for selective oxidation of benzyl alcohols using molecular oxygen as oxidant
(Makerere University, 2020-10)ABSTRACT This dissertation presents sustainable and efficient processes for the oxidation of benzyl alcohols using molecular oxygen as the oxidant and catalyzed by Ag-Cu bimetallic catalysts supported on polyoxometalates ... -
Effect of basin evolutionary factors on reservoir quality of the Semliki basin, Western Uganda
(Makerere University, 2021-02-06)Sedimentation in the Semliki basin is controlled by tectonics and climatic changes. These factors together control the patterns of river drainage, that create variations in sediments composition, heterogeneities in the ... -
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 ... -
Characterization of Reservoir Properties for the Kisegi Formation in Semliki Basin, Albertine Graben, Western Uganda using Rock Physics Diagnostics
(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 ... -

Sorption kinetics and degradation of chlorpyrifos in selected Uganda soils using mixed solvents
(Makerere University, 2019-10)The purpose of this study was to determine sorption kinetics using mixed solvents and degradation of Chlorpyrifos in tropical soils. The information is important to understand the behaviour and fate of Chlorpyrifos in ... -
Isolation and structural elucidation of antibacterial triterpenoids compounds from stem bark of Psorospermum Febrifugum (spach var. febrifugum)
(Makerere University, 2019-10)In this study, Psorospermum febrifugum stem bark was investigated for the antibacterial compounds present in its stem bark. The stem bark of Psorospermum febrifugum was collected in Mpigi District, Misindye hill in Buwungu ... -
The effects of PMD in buried and aerial single mode and polarization maintaining fibers and performance of direct and external modulation techniques at high speed data rate
(Makerere University, 2019-06)Optical fiber transmission is greatly affected by dispersion and in this study, we experimentally investigate angular displacement and speed of state of polarization in Single Mode Fibers (SMF) and Polarization Maintaining ... -
Utilisation of excess power generated by stand-alone solar photovoltaic system: a case study in Uganda
(Makerere University, 2019-11-25)Stand-alone solar PV systems are increasingly installed worldwide. For reliability, these systems are mostly oversized because of the intermittent nature of the source of energy and to cater for days of autonomy. During ... -
Indoor radon concentrations in the dormitories of selected secondary schools in Otuke District, Northern Uganda
(Makerere University, 2019-12-05)Inhalation of radon and its progeny is the most significant source of natural radiation exposure to human population. Over 50 % of the natural background radiation comes from radon (222Rn). This study measured background ... -
