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 ... -
Effect of municipal effluent on the water quality of Pece Stream and on selected vegetables along its shoreline in Gulu Town, Northern Uganda
(2016-09-20)The restoration of peace in Northern Uganda has caused a rapid population growth in Gulu Municipality, which in turn has elevated anthropogenic pollution over the recent past. Pece stream being the only drainage system in ... -
Thermal performance of an oil-rock heat storage system
(Makerere University, 2018-09)Experiments to evaluate the thermal performance of an oil-rock thermal energy storage system by direct heating from the base of the storage tank are presented. The oil-rock TES system consisted of a combination of sunflower ... -
Quantifying the burden of foot and mouth disease in selected districts in Uganda
(2018-12)One cycle of foot and mouth disease is considered for a susceptible, infected and removed epidemiological model. Analysis of the basic properties of the SIR epidemic model with direct transmission of infection and numerical ... -
Organochlorine pesticides in honey and soils from areas surrounding an abandoned store at Masindi District, Western Uganda
(Makerere University, 2018-12-06)This study determined the concentrations of organochlorine pesticides (OCPs) in soil and honey from areas surrounding an abandoned store at the Masindi District Headquarters. The samples were extracted using solid-liquid ... -
Efficacy of selected chemical and biological binders in reducing aflatoxin concentrations in poultry feeds
(Makerere University, 2018-12-04)To support the massive increase in poultry production in Uganda, there is need to improve the quality of feed in terms of nutrient composition and absence of harmful and toxic materials. Feed can be contaminated by aflatoxins ... -
Fixation of carbon dioxide into epoxides to form cyclic carbonates using silicate based catalysts
(Makerere University, 2018-11)This study aimed at developing silicate based catalytic systems for the fixation of carbon dioxide (CO2) into epoxides to form cyclic carbonates. Catalytic activity of selected naturally occurring silicates including: ... -
Localization in different categories
(2018-11-30)Localization can be thought of as a systematic way of inverting morphisms in a category to construct a new one. This can be formulated accurately in terms of a universal property. In this study, we looked at localization ... -
A mathematical model for the transmission dynamics and optimal control strategy of Coffee Wilt disease
(2018-10-18)The main objective of this study was to formulate a mathematical model for the transmission dynamics and optimal control strategy of coffee wilt disease (CWD) in Uganda. A deterministic model for the transmission dynamics ... -

(2018-11)The overall performance of the 830 kWp ground-mounted grid-connected PV power plant at Kamuzu International Airport in Malawi has been evaluated on monthly and yearly basis over the monitoring period of four years, from ... -
Isolation and identification of compounds from the leaves of Secamone africana (oliv.) bullock used locally to treat malaria
(2018)Traditional medicine is an affordable and accessible source of primary health care for treatment of tropical diseases such as malaria. Malaria in developing tropical countries has been treated using preparations of traditional ... -
Exploring the use of Landsat imagery in monitoring chlorophyll-a and lake surface temperature in Lake Victoria
(Makerere University, 2018-08)In Uganda, Lake Victoria is a livelihood of about 40 million people and a home to aquatic life. It is utilized for the different activities like tourism, industry, transport and fisheries. However, it contains substances ... -

How variation of turbidity of bleached oils characterizes purity oil and bleaching processes
(ARC, 2017)Freundlich and Langmuir isotherms have always been developed using changes in absorbance of oils. In this study we have investigated use of changes in turbidity of oils to assess bleaching efficiency and develop Freundlich ... -
L-band and VHF response to scintillation activity during the ascending phase of sunspot cycle 24 in the Equatorial Region of East African
(Makerere University, 2014-05)Ionospheric scintillation is the rapid change in the phase and or the amplitude of a radio signal as it passes through small scale plasma density irregularities in the ionosphere. These scintillations, not only can they ... -
The quality and characteristics of cotton and sunflower oil bleached using clays from Iliri, in North Eastern Uganda
(European Centre for Research Training and Development UK, 2017)Bleaching is known to alter the composition of edible oils as it removes impurities and certain food nutrients. The characteristics of bleached oil are strongly related to type bleaching medium, temperature at which ... -
