(Makerere University., 2023-09-12)Assessing the conservation status of species according to their extinction risk is a major step in conservation planning and resource prioritization. To date, most of the assessments have been conducted on global level; ... -
ELISA-based quantification and role of callose in the development of banana Xanthomonas wilt disease in banana
(Makerere University, 2023-08-16)Xanthomonas vasicola pv. musacearum (Xvm) which causes banana Xanthomonas wilt (BXW) disease in banana shows incomplete systemic movement (ISM) in different banana organs and lateral shoots. This ISM phenomenon is yet ... -
Statistical Lagragian characterization of the steady ABC and meandering jet flows.
(Makerere University., 2023-10-27)In this study, we carried out a statistical Lagrangian characterization of the steady ABC and Meandering jet flows. The ABC flow is a three-dimensional velocity field which gives rise to chaotic trajectories while the Meandering ... -
Molecular characterization and incidence of viruses affecting water melon and pumpkin production in Uganda.
(Makerere University., 2023-10-23)Watermelons and pumpkins are cultivated in Uganda for their leaves, fruits, and seeds, thereby contributing to food, nutrition and income security. However, there is limited research and information on constraints and ... -
The dynamics of cyanobacteria and potential threats of cyanotoxins in Uganda: a case of Murchison Bay and Napoleon Gulf, northern Lake Victoria
(Makerere University, 2023-09)Lake Victoria has diverse cyanobacteria associated with varying types and concentrations of cyanotoxins. Over 31 variants of microcystins (MC) have been identified in the lake with MC-LR, MC-RR and MC-YR as the commonest. ... -
Prediction of hourly global solar radiation incident on a horizontal surface in Kampala using Markov Chain Model.
(Makerere University., 2023-09-04)The present investigation delves into the feasibility of predicting global solar radiation (GSR) on horizontal surfaces within Kampala using the Markov Chain Model (MCM). This predictive data is crucial for informing ... -
Prediction of global solar radiation on tilted surfaces using Artificial Neural networks in Kampala, Uganda.
(Makerere University., 2023-09-29)In this study, we developed a model using artificial neural networks to predict average daily global solar radiation on tilted surfaces based on sunshine hours, minimum temperature, maximum temperature and relative humidity ... -
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 ... -
Subsurface facies analysis of the paleogene formations, nahal field, melut basin,south sudan
(Makerere University, 2023-09)The present work highlights the results of the facies study conducted to identify lithologic heterogeneity and determine petrophysical properties from six wells in Nahal oilfield in South Sudan with the aim of assessing ... -
Assessment of Geological Controls on Reservoir Heterogeneity in Kingfisher Oilfield Lake Albert Basin, Western Uganda
(Makerere University, 2023-08-14)The Kingfisher oilfield is one of the key discovery fields found in the Albertine Graben located in the Lake Albert basin. The Kingfisher reservoir zones are characterized by variations in facies distribution, pressure ... -
A 3d basin modelling approach to the assessment of hydrocarbon potential of Lake Edward basin, western Uganda
(Makerere University., 2023-09-06)Lake Edward basin is a rift basin located in the extreme south of the Ugandan portion of the western arm of the East African Rift System (EARS), popularly known as the Albertine Graben. 3D basin modelling approach was ... -
Drug-resistant bacterial contamination and efficacy of selected herbal medicines sold in Kampala city, Uganda (MakIR) (Unpublished PhD Thesis) Makerere University Kampala Uganda
(Makerere University., 2023-08-19)Background: Antimicrobial resistance (AMR), is when pathogens such as bacteria evade activities of drugs to which they were once susceptible, causing treatment failure. The AMR is escalating and is among the leading causes ... -
Brain tumor origin localization via iterative methods
(Makerere University, 2023-08-15)We study the brain tumor growth with and without treatment by using the commonly used mathematical PDE models of the Reaction-diffusion type. The models describe tumor cell density change over time due to cell proliferation, ... -
