Upgrading and characterization of smectite from selected volcanic sediments of Eastern Uganda
(2015)Natural clays occur as mixtures of many clay minerals and remains of the rocks that underwent diagenesis to yield the clays. As weathering of clay soils never ceases it may not be possible to mine single clay minerals. The ... -
Using trace metals, peroxide, acid and iodine values to characterize oils bleached using clays from Central and Eastern Uganda
(2014)The decrease in content of iron in the bleached oils was highest for all oils bleached. The content of copper showed the smallest change. The decrease in copper content for palm oils decreased from 0.2ppm to 0.1ppm when ... -
Inhibitory effect of anti-paraflagellar RODc antibodies on in-vitro growth of trypanosoma brucei brucei
(Makerere University, 2015-10)The flagellum of a trypanosome possesses a unique compact filamentous structure termed as the Paraflagellar rod (PFR), conserved among trypanosomatids, euglenoids, and dinoflagellates. The PFR is expressed in all life cycle ... -
Barriers to implementation of Uganda’s national industrial policy: A case study of the Steel Mills Industry
(Makerere University, 2014-12)This research is a descriptive study of Uganda’s national industrial policy implementation state. The study was conducted in the Steel mills industry with a major aim of assessing the process of implementing Uganda’s ... -
Groundwater physical and hydrochemical characteristics of the weathered crystalline rock aquifers in Kamuli district, Eastern Uganda
(Makerere University, 2015-10)Deeply weathered crystalline rocks constitute important groundwater aquifers that provide accessible and reliable sources of safe domestic water supply in Kamuli District in eastern Uganda. Inadequate characterization of ... -
Prevalence of varroa: Influence of altitude and management practices on the degree of infestation in Uganda
(Makerere University, 2015-10)Varroa mite has been a concern and worry to the bee scientists and beekeepers since it was first discovered in 1904, and continues to be the most serious parasite of honeybees. It causes clinical symptoms on the brood and ... -
Ethnobotanical, phytochemical and antiplasmodial studies of Neoboutonia Macrocalyx L
(Makerere University, 2014)Malaria is one of the leading causes of mortality and morbidity due to resistance of the parasite to the cheap and available antimalarials. The need for effective new and cheap alternative antimalarials is therefore of ... -
The effect of different mordants on strength and stability of colour produced from selected dye-yielding plants in Uganda.
Five dye-yielding plants namely; Morinda lucida, Vitellaria paradoxa, Syzgium cordatum, Albizia coriaria and Justicia betonica were investigated in this study for the effect of mordant on strength and stability of colour. ... -
Stochastic model for Langerhans Cells and HIV dynamics: In vivo
Many aspects of the complex interaction between HIV and the human immune system remain elusive.Our objective is to study these interactions, focusing on the specific roles of Langerhans cells (LCs) in HIV infection. In ... -
Detection, distribution, and genetic variability of European mountain ash ringspot-associated virus.
European mountain ash ringspot-associated virus (EMARAV) was recently characterized from mountain ash (rowan) (Sorbus aucuparia) in Germany. The virus belongs tentatively to family Bunyaviridae but is not closely related ... -
Determination of levels of selected antibiotics in the waters of the Nakivubo Channel, Kampala (Uganda)
(Makerere University, 2014-12)Antibiotics are one of the most successful forms of chemotherapy developed by modern science, many lives have been saved and diseases or infections that would cause death of humans and pets or lead to poor crop performance ... -
Designing and Performance Evaluation of Biochar Production in a Top-Lit Updraft Up-scaled Gasifier
(Scientific Research Publishing, 2015)The Original Belonio Rice Husk Gasifier (OBRHG), initially of height of 0.6 m, diameter of 0.15 m and thickness of 0.025 m was tested for biochar production through air gasification of rice husk (RH) and the design was ... -
Gasification of biochar from empty fruit bunch in a fluidized bed reactor
(MDPI AG, 2010)A biochar produced from empty fruit bunches (EFB) was gasified in a fluidized bed using air to determine gas yield, overall carbon conversion, gas quality, and composition as a function of temperature. The experiment was ... -
Improved gasification of rice husks for optimized biochar production in a top lit updraft gasifier
(Scientific Research Publishing, 2014)Biochar is a solid material obtained from the carbonization of biomass. If properly produced, it is useful for soil application to enrich plant values. Rice husk (RH) waste, an abundant agricultural by-product, was gasified ... -
Sustainable technologies for small-scale biochar production—a review
(Scientific Research Publishing Inc., 2015)Charcoal has found enormous application in both agriculture (AKA biochar) and other sectors. Despite its potential benefits, small scale technologies relevant for its production remain a challenge. Technologies striking a ... -
Population dynamics of fruit flies (diptera: tephritidae) in mango growing areas of Luwero and Wakiso Districts, Uganda.
(Makerere University, 2014-06)Population dynamics of major fruit flies (Diptera: Tephritidae) infesting mango orchards were monitored for 12 months using methyleugenol, trimedlure, terpinyl acetate and protein-baited traps in 2011 in Luwero and Wakiso ... -
