Forage diversity and preferences by honeybees Apis mellifera (hymenoptera: apidae) in Masaka district, Uganda
(Makerere University, 2021-01-25)The honey production potential for Uganda and in particular Masaka District has hardly been fully exploited and thus the honey production capacity has since remained low. Knowledge on suitable foraging options for honeybees ... -
Potential Hydrogeological Contaminants derived from petroleum activities in the Albertine Graben
(Makerere University, 2021-02)Current understanding of the hydrogeological characteristics of rift-margin environments is limited and not well reconciled to large- scale conceptual models of rift evolution. In Uganda with substantial dependence on ... -
Diversity and distribution of lepidopteran floral visitors in different land-use types in Mabira Central Forest Reserve, Uganda
(Makerere university, 2021)Globally, the population of insect pollinator species is in decline at local and landscape levels due to land-use intensification occurring in different land-use types. Insect pollinators in Uganda are not well researched ... -
Evaluation of modified collection drums and light emitting diode bulbs for trapping the edible long-horned grasshopper, ruspolia differens (serville) in Uganda
(Makerere University, 2021-04-09)The long-horned grasshopper (Ruspolia differens) is a delicacy in Uganda and many African countries. It is traditionally trapped at night during the swarming seasons using mercury bulbs that consume a lot of electric energy ... -

Microbial contaminants in wild harvested and traded edible long-horned grasshopper, Ruspolia differens (Orthoptera: Tettigoniidae) in Uganda
(Makerere University, 2021-04)Edible insects are now globally recognised as alternative sources of food and feed. Currently, over 470 spp of insects are consumed in Africa alone, with Ruspolia differens being the most common in central Uganda. Harvesting ... -
Synthesis, catalysis and Nitrosyl derivatives of Iron(ii) complexes bearing Pentadentate Polypyridyl ligands
(Makerere University, 2021-04-06)The work described in this thesis reports the synthesis, characterization, and solution chemistry of a series of new pentadentate polypyridyl ligands and their corresponding Fe(II) complexes. The ligand structure was based ... -
Development of a sensible heat packed bed energy storage system for medium temperature applications
(Makerere University, 2020-11-01)Utilization of solar energy can be a strategy to provide clean and cheap energy for various purposes such as cooking. Unfortunately, solar energy is intermittent and unreliable for continuous usage. As a result, it ... -
Distribution and incidence of the oil palm weevil Rhynchophorus Phoenicis (Fabricius, 1801) (Coleoptera: Curculionidae) in selected districts of Uganda
(Makerere University, 2020-10)The weevil Rhynchophorus (Herbst) (Coleoptera: Curculionidae) is a key pest of oil palm worldwide, but information on its infestation of crops in Uganda is eleven decades old, therefore, outdated. The current study was ... -
Farmers’ awareness of bean leaf beetles (Ootheca spp.) and the virulence of Aspergillus flavus and Metarhizium Anisopliae against these pests in Uganda
(Makerere University, 2021-02)The common bean (Phaseolus vulgaris L.) is a widely grown crop and plays a key role of food and income security in Uganda. However, production of the crop is constrained by field insect pests including bean leaf beetles ... -
Occurrence, eco-toxicological risk assessment, sorption and degradation of selected emerging organic chemical pollutants in water and sediments of Lake Victoria, Uganda
(Makerere University, 2021-03)The occurrence of emerging chemical pollutants (ECPs) including; 25 pharmaceuticals, 11 personal care products, 6 plasticizers and 8 organophosphorus flame retardants was investigated in water and sediment samples collected ... -
Synthesis, Anti-plasmodial and Anti-microbial Properties of Carvotacetone Analogues
(Makerere University, 2021-03-30)Resistance of plasmodia parasites, Cryptococcus neoformans and methicillin resistant Staphylococcus aureus to the available medications are a major cause of concern worldwide. This situation necessitates the requirement ... -
Antiplasmodial activity, Toxicity and Phytochemistry of Selected Plant Species used by Rukararwe and Prometra Herbalists in Treatment of Malaria in Uganda
(Makerere University, 2021-03-30)Resistance of malaria parasites to known antimalarial drugs necessitated to finding new drugs from natural products which are readily available to treat malaria. The study documented; medicinal plants used in malaria ... -
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 ... -
Effect of thermal pretreatment of East African highland cooking banana peels on biogas production
(Makerere University, 2021-03)East African Highland Cooking Banana peels (EAHB peels) possess suitable properties for biogas production through anaerobic digestion however hydrolysis of EAHB Peels like other lignocellulosic materials is slow and therefore ... -
