Wild edible plants used by communities in and around selected forest reserves of Teso-Karamoja region, Uganda
(BMC, 2019-01-09)Background: The consumption of wild plants is an ancient tradition which serves multiple purposes. Cognizant that Teso-Karamoja region is frequently affected by food scarcity and is not adequately surveyed for its flora, ... -
Fuel value indices of fuelwood species and accuracy of K-nearest neighbour technique in woody biomass estimation in Masindi and Nebbi Districts, Uganda
(Makerere University, 2015-11)Biomass is still the major energy source in developing countries like Uganda. This implies that prioritizing high fuel potential fuelwood species and routine monitoring of stocks is paramount. This study identified ten ... -
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 ... -
Diversity and distribution of macro-invertebrates associated with Anopheles gambiae breeding habitats in selected villages along River Sezibwa, Uganda
(Makerere University, 2018)Members of the Anopheles gambiae sensu lato (s.l.) are among the main vectors that carry Plasmodium which causes malaria. Immature stages of the vectors and other associated species share breeding habitats with other ... -
Morphological and molecular characterization of bivalves with respect to their diversity and distribution in Murchison Bay, Lake Victoria, Uganda
(Makerere University, 2018-12)This study was designed to characterize bivalves in Murchison Bay using morphological and molecular approaches. The diversity and abundance of bivalves and the effect of abiotic factors were also determined from eight sites ... -
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 ... -
Infestation levels and control of the Varroa mite ((Varroa destructor) in managed honey bee colonies from selected agro ecological zones of Uganda
(Makerere University, 2018-10)The Varroa mite, Varroa destructor (Arachnida: Acari: Varroidae) is an ectoparasitic mite of the honey bee (Apis mellifera). It was first detected in East Africa in 2009. Currently, no control strategies have been put in ... -
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 ... -
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 ... -
