Distribution solutions to ordinary differential equations with polynomial coefficients on the real line
(Makerere University, 2012-04)In this study we consider the Weyl algebra A1(C) that consists of differential operators P of the form P = pm(x)"m + pm−1(x)"m−1 + . . . + p1(x)" + p0(x), (1) where {p"(x)} are polynomials which in general may have ... -
Diurnal and seasonal variability of total electron content observed at Kampala in the Equatorial Region
(Makerere University, 2012-12)Total electron content (TEC) is a vital and most dominant ionospheric parameter that can cause GPS signal delays, signal degradation and in extreme cases loss of lock. This results into inefficient operations of ground and ... -
Dividend maximisation in an insurance process compounded by risky and non-risky investments.
(Makerere University., 2024-02-07)Shareholders of an insurance company would expect maximum dividends from their investment in insurance companies for decades. Therefore, there is a need for managers of insurance companies to pay out appealing dividends ... -
The dual of local cohomology modules
(Makerere University, 2022-12-07)Let R be a Noetherian commutative local ring with unity, a be an ideal of R and M be an R-module. Local duality is one way of studying local cohomology modules by obtaining their dual modules. When M is a finitely generated ... -
Earthworms as alternative protein ingredient in poultry feed.
(Makerere University, 2018-03-01)In poultry feed accounts for 70% of the total cost of production hence there is a need to have a high-quality and yet low cost feed. The protein sources used in poultry feeds (Rastrineobola argentea & soy beans) are also ... -
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 clouds on the photosynthetically active radiation received in Kampala, Uganda.
(Makerere University., 2023-09-13)Photosynthetically active radiation (PAR) plays an important part in climate change and ecological processes. Few PAR measurements are available some in countries such as Uganda. Thus it is important to investigate the ... -
Effect of Heavy Metal Concentration on Natural Radioactivity Levels in Selected Wetlands in Kampala, Uganda.
(Makerere University, 2022-12-22)Top soil samples and accompanying yams were analyzed for natural radionuclide constituents and heavy metal concentrations using gamma - ray spectrometric methods and atomic absorption spectrometery (AAS), respectively. The ... -
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 ... -
The effects of PMD in buried and aerial single mode and polarization maintaining fibers and performance of direct and external modulation techniques at high speed data rate
(Makerere University, 2019-06)Optical fiber transmission is greatly affected by dispersion and in this study, we experimentally investigate angular displacement and speed of state of polarization in Single Mode Fibers (SMF) and Polarization Maintaining ... -
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 ... -
Estimation of Ground Motion Levels Due To Earthquakes of the Albertine Graben In Uganda.
(Makerere University, 2021-02-17)Present probabilistic seismic hazard maps for the Albertine Graben, for peak ground acceleration and the spectral ordinate at periods of 0.2seconds and 1.0seconds;with 10 % probability of being exceeded on average once in ... -
Estimation of Radiological Effects and Modeling Radionuclide Transfer to Milk and Fish in Kisoro, South-western Uganda
(Makerere University, 2024-04-17)Exposure to natural radiation energy (ionozing radiation) is one of the primary causes of radiation ailments like cancer. Radioactivity is widely spread in the earth’s environment and it exists in various geological ... -
Evaluating the shielding properties of selected building materials used in Kampala, Uganda for gamma radiation
(Makerere University, 2021-04)Humans are continuously exposed to ionizing radiation. For high ionizing radiation levels, shielding is needed to mitigate unwanted exposure. In this study, Shielding properties of selected local building materials used ... -
