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 ... -
Effect of Kalerwe Abattoir wastewater on the water quality of Nsooba Channel
(Makerere University, 2018-11-23)The unregulated discharge of industrial wastewater from point sources into inland fresh water aquatic systems coupled with the resultant deterioration of water quality, are largely un-documented in many developing countries, ... -
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: ... -

(2018-11-30)Gastrointestinal parasites are a well-known threat to non-human primates‟ health and conservation. These parasites affect non-human primates‟ ecology and evolution, population growth and regulation, and community biodiversity. ... -
Optimising spawning conditions and growth performance of larvae and juveniles in Barbus altianalis (Boulenger, 1900)
(2018-11)Barbus altianalis is an indigenous cyprinid that lives in lacustrine-riverine environments with limited distribution to Upper Victoria Nile and lakes Victoria, Edward, George and their associated rivers. The species is a ... -
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 ... -
Fern species composition, richness and selected traits in forest fragments around North East of Kibale National Park, Uganda
(2018-10-25)Few studies have investigated how the effects of disturbance on ferns specifically on their traits vary with levels of forest disturbance even though such research could provide information necessary to stop further ... -
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 ... -
Cowpea varietal influence on Striga hermonthica [(Del.) Benth] in finger millet (Eleusine coracana (L.) Gaertn) fields in Pallisa District, Eastern Uganda
(Makerere University, 2018-06)Level of Striga hermonthica infestation is beyond finger millet tolerance levels, especially for varieties grown in Uganda. Efficacy of Striga control measures have been variously investigated with limited success, either ... -
Population morphometric variation and condition of Barbus Altianalis (Boulenger 1900) in the River Nile, Lake Edward and Kazinga Channel – Uganda
(Makerere University, 2018-10-12)This study used morphometric characteristics and fish condition to compare populations of Barbus altianalis from the River Nile, Lake Edward and Kazinga Channel. Morphological variation was determined using multivariate ... -
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 ... -
