The political and institutional dimensions of agricultural extension reform process in Uganda: Experiences of the National Agricultural Advisory Services
(Makerere University, 2014)Agricultural extension reforms initiated in the 1990s were an offshoot of a global movement for reforming the national extension systems in developing countries, which started late in the twentieth century, an era characterized ... -
Spatial and matrix influences on the biogeography of insect taxa in forest fragments in Central Uganda
(Makerere University and University of Bergen, 2016)How best to manage forest patches, mitigate the consequences of forest fragmentation, and enable landscape permeability are key questions facing conservation scientists and managers. In Uganda, most protected forests have ... -
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 ... -
Amphibian diversity patterns in the Namulonge agricultural landscape
(Makerere University, 2017)Uganda’s agricultural landscapes are patterns of cultivated areas and semi-natural elements. Although comprising only a small fraction of the total area, semi-natural elements provide habitats for most of the landscape ... -
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 ... -
Ectoparasites of small mammal communities in restored oil prospecting sites in Buliisa and Hoima Districts
(Makerere University, 2015-10)A study of small mammal diversity and their ectoparasites was undertaken in seven restored oil exploration sites within the Albertine Graben between April and August 2013. Small mammals were surveyed using Sherman, Museum ... -
Response of amphibian communities to forest degradation in Mabira Central Forest Reserve, Uganda
(Makerere University, 2017)The relationship between amphibian diversity and forest degradation was evaluated in Mabira Forest Reserve, Central Uganda. To achieve this, the study area was classified into three forest categories (i.e. degraded, ... -
Spectroscopic analysis of heterogeneous biocatalysts for biodiesel production from expired Sunflower cooking oil
(Hindawi Publishing Company, 2015)The study characterized heterogeneous biocatalyst synthesized from sucrose, saw dust, and chicken egg shells using Fourier Transform Infrared (FTIR) spectroscopy coupled with Attenuated Total Reflectance (ATR) technique. ... -
Heterogeneous biocatalysts for production of biodiesel from waste vegetable oil and effect of crude glycerol on combustion properties of briquettes
(Makerere University, 2017)The conversion of spent vegetable oils into biodiesel using biocatalysts provides both environment friendly and also innovative ways to manage wastes that would otherwise end in the environment. This study explored the use ... -
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 ... -
Effective methods of processing soybean products used in formulating diets for Nile Tilapia (Oreochromis niloticus Linnaeus)
(Makerere University, 2016)The increasing demand for the silver cyprinid (Rastreneobola argentea), an indigenous fish species to Ugandan waters by humans has pushed the fish meal prices high; making its use in aquafeeds less achievable. This calls ... -
Adsorption behavior of acid-leached clays in bleaching of oil
