The numerical range of linear relations and stability theorems
(Makerere University, 2022)The nullity, deficiency and index of a linear relation A from a linear space X to a linear space Y are defined as the dimension of the null space of A, the codimension of the range of A and the difference between the nullity ... -
Anti-bacterial activity and characterization of compounds from the leaf extract of Solenostemon Latifolius Hochst.ex benth.
(Makerere University, 2021-03)Infectious diseases have continuously been reported among the leading causes of death in the world. These include bacterial infections like tuberculosis and pneumonia. Several antibiotics have been used against these ... -
Anti-plasmodial activity and phytochemical analysis of leaf extract of Chenopodium Opulifolium Schrad. EX W.D.J. Koch and Ziz used in Uganda
(Makerere University, 2022-04-28)Malaria is a life-threatening disease caused by Plasmodium species. It had one of the highest motality and morbidity rates globally. with 229 million cases and 409,000 malaria death in 2019. In Uganda. Malaria has an ... -
Assessing Enrofloxacin use practices and residue levels of Enrofloxacin/Ciprofloxacin in breast and liver tissues of broiler chicken sold in selected markets in Kampala Capital City-Uganda
(Makerere University, 2022)Human exposure to veterinary drugs like fluoroquinolones occurs due to the presence of their residues in foods from animal sources in varying concentrations. The existence of antibiotics residues in foodstuff can pose great ... -
Investigating the characteristics of x-ray emission from Black Hole Binaries V4641 Sagittarii and V1033 Scorpii from Chandra Data
(Makerere University, 2022)X-ray emission processes in binary systems with early-type stars present a much more complex scenario, in which magnetic fields also play a key role. Despite a very wide range of phenomena that have been observed to occur ... -
Total electron content estimation in low latitude region of East Africa using NeQiuck2 model
(Makerere University, 2022-02)Modelling ionospheric total electron content (TEC) is important for geodesy, surveying, radio wave propagation, understanding of space weather dynamics and error correction in relation to Global Navigation Satellite Systems ... -
The occurrence of selected antibiotics in fish and benthic invertebrates (oligochaetes) from lake victoria, uganda
(Makerere University, 2022-04-14)The environmental occurrence of antibiotics has been a source of growing concern. The vast increase in production and usage of antibiotics is due to urbanization in areas of Lake Victoria basin. This has contributed to ... -
Solutions to a non-linear Diophantine equation of Pillai type
(Makerere University, 2022-04-07)Let $ \{F_n\}_{n\geq 0} $ be a sequence of Fibonacci numbers defined by $$ F_{0}=0, ~ F_{1}=1 ~~ \text{and} ~~ F_{n} = F_{n-1}+ F_{n-2} ~~ \text{for} ~~ n\geq 2. $$ In this research, we find all integers $c$ with at least ... -
Geological assessment of heavy metals' soil contamination by drilling waste discharge, Palogue Fields, Melut Basin, South Sudan
(Makerere University, 2022-03-31)Oil and gas operations produce wastes that are potentially toxic to the environment. The waste deposited into reserve pits can contaminate soil, groundwater, and surface water with heavy metals and other toxic substances ... -
