Geological assessment of heavy metals' soil contamination by drilling waste discharge, Palogue Fields, Melut Basin, South Sudan
(Makerere University, 2022-03-31)Oil and gas operations produce wastes that are potentially toxic to the environment. The waste deposited into reserve pits can contaminate soil, groundwater, and surface water with heavy metals and other toxic substances ... -
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 ... -
Geometric mean-reverting approach to modelling stock prices at the Uganda securities exchange:case of Stanbic bank Uganda
(Makerere University, 2022-12-21)An accurate stock price prediction brings advantages to investors and benefits the stakeholders directly since it provides enough information to make better investment decisions towards the future. This dissertation aims ... -
Gravity and magnetic data analysis to detect the origin of carbon dioxide in Semliki Basin, Albertine Graben
(Makerere University, 2011-12)Semliki basin is one of the most prospecting basins for Petroleum exploration in Uganda. An exploratory well (Turaco-3) drilled to the depth of 2960 m by Heritage Oil and Gas Limited in the Semliki Basin encountered a ... -
Heavy metal and nutrient loading of river Rwizi by effluents from Mbarara municipality, western Uganda
(Makerere University, 2012-09)The rapid expansion of Mbarara town in Western Uganda has significantly elevated its anthropogenic pollution over the recent past. It is feared that the increasing volume of untreated effluent discharge might find its way ... -
Hierarchical models and spatio-temporal processes in data analysis
(Makerere University, 2021-12)Spatio-temporal processes evolve in space and time. As a consequence data from such processes, usually possess both temporal and spatial dependence which have to be reflected by fitted stochastic models. The existing ... -
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 ... -
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 ... -
Interpretation of structural domains beneath Lake Edward- George basin, Southern Uganda from seismic data
(Makerere University, 2022-05-10)The recent oil and gas discoveries in Uganda particularly in the Albertine Graben have made the country one of the economically potential hydrocarbon provinces in the world thus causing an increased exploration of new areas ... -
Investigating the characteristics of x-ray emission from Black Hole Binaries V4641 Sagittarii and V1033 Scorpii from Chandra Data
(Makerere University, 2022)X-ray emission processes in binary systems with early-type stars present a much more complex scenario, in which magnetic fields also play a key role. Despite a very wide range of phenomena that have been observed to occur ... -
Iodisation of Lake Katwe salt, Kasese District
(Makerere University, 2009-11)The raw rock salt was analysed for chemical composition, refined and then iodised. The selected species determined are those known to hinder iodine retention in edible salt, namely; sulphates 20.7 % w/w, carbonates 31.7 % ... -
Isolation and characterisation of compounds from Helichrysum odoratissimum (L.) Sweet and their activity on oral bacteria.
(Makerere University., 2023-11-27)Dental caries (DC) and Periodontal diseases (PD) are the most common oral diseases in the world today. Conventional treatment of these diseases relies on approaches that are not easily accessible to most rural populations, ... -
