Power dynamics and marketing efficiency of silver cyprinid (Rastrineobola Argentea) at Kiyindi Landing
(Makerere University, 2023-12)Small pelagic species are considered major economic resource involving several actors to derive livelihoods. The high number of actors increases competition and may result in unequal distribution of benefits depending on ... -
Diversity of the bean anthracnose pathogen, colletotrichum lindemuthianum (sacc. and magn.) from major bean agroecological zones of Uganda
(Makerere University, 2023-11)Anthracnose disease in common bean (Phaseolus vulgaris L.) is a major disease caused by the fungus Colletotrichum lindemuthianum. Management through host-plant resistance is the best management option, but is constrained ... -
Photocatalytic Degradation of Methylene Blue Dye in Wastewater Using Iron-Doped Titanium Dioxide Nanoparticles.
(Makerere University., 2023-11-22)The photocatalytic degradation of methylene blue dye in wastewater was investigated using iron (III)-doped titanium dioxide nanoparticles. The nanoparticles were synthesized via the sol-gel method and calcined at a temperature ... -
Health risk assessment for exposure of lead and cadmium in herbal medicines sold in Kalerwe market, Kampala, Uganda
(Makerere University, 2023-11-17)Herbal medicine use provides about 80% of primary health care globally. There exists a toxicity risk to the population from consumption of herbal medicines owing to the lack of knowledge on the herbal medicine physicochemical ... -
Formulation, Nutritional value, and Shelf stability of House Cricket-Blended Flours as Potential Complementary Foods
(Makerere University, 2022-03-22)Undernutrition, due to the poor quality of complementary foods, among children between 6 – 23 months remains a nutritional burden in sub-Saharan Africa. Strategies such as food-to-food fortification, and supplementation, ... -
The role of the endothelial nitric oxide synthase gene polymorphisms in sickle cell disease.
(Makerere University., 2023-11-16)Sickle cell disease (SCD) is a red blood cell disorder which results from a single mutation in the β- globin chain inducing the substitution of amino acid valine for glutamic acid at the sixth amino acid position. However, ... -
Relationship between proinflammatory cytokines and associated coagulopathies among COVID-19 patients at Mulago national hospital, Kampala
(Makerere University., 2023-11-04)Cytokine storm and coagulopathy are two main complications of COVID-19 and are more profound in severe cases. Hyperinflammation and hypercoagulability are two common features, accompanied by a higher rate of morbidity and ... -
Spatial risk estimation of parasitic infestations of pond and cage cultured Nile tilapia (Oreochromis niloticus) in the Lake Victoria Crescent, Uganda.
(Makerere University., 2023-11-09)In pond and cage culture systems, parasites live concurrently with fish. However, parasitic infestations arise when this relationship is interfered with. This comes about when there is poor water quality, poor nutrition, ... -
Assessment of the distribution and conservation status of non-haplochromis fish species in Uganda.
(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; ... -
