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 ... -
On generalized solutions of locally Fuchsian ordinary differential equations
(Scientific Advances Publishers, 2018)We consider an m-th order constant coefficient locally Fuchsian ordinary differential equation at the origin ( ( ) ( ) ( )) ( ) 0 0 0 0, 1 0 1 ∇ + 1 ∇ + + ∇ + = − r − r r y x m m m … where dx d x ∈ R, ∇ = x and prove ... -
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 ... -
Abundance and some aspects of breeding biology of African Catfish (Clariasgariepinus) in Kafu Riverine wetland
(Kikonyogo, F.E. (2017). Abundance and some aspects of breeding biology of African Catfish (Clariasgariepinus) in Kafu Riverine wetland. Unpublished masters dissertation. Makerere University, Kampala, Uganda., 2017)Various studies on the ecology and biology of Clarias gariepinus have been carried out elsewhere by different scholars but not specific to Kafu Riverine wetland, because of its intraspecific ecological variations, fisheries ... -
Adsorption behavior of acid-leached clays in bleaching of oil
(Scientific Research Publishing, 2015)The available data have shown that acid-leached clays had sites for adsorption of impurities in oils. Data obtained on residual impurities in cotton and sunflower-seed oils bleached with the same clay materials produced ... -
The elemental, mineralogical, IR, DTA and XRD analyses characterized clays and clay minerals of Central and Eastern Uganda
(Scientific Research Publishing, 2015)The results on the elemental and mineralogical compositions of clays from Central Uganda differed from those from the volcanic sediments of the Mt. Elgon in Eastern Uganda. Utilisation of the two types of clays should ... -
Distinguishing kaolinites and smectite clays from Central and Eastern Uganda using acidity, pH, colour and composition
(Scientific Research Publishing, 2015)The Langmuir isotherms of 1-aminobutane in isohexane slurries showed increase in clay acidity with increase in concentration of mineral acid used to leach the clay as well as the temperature at which the clay was thermally ... -
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 ... -
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.
