Mechanical properties of ceramic floor tiles made from selected minerals in Uganda
(Kyambogo University [unpublished work], 2012-06)This study was designed to produce porcelain floor tiles using raw materials found in Uganda and to determine mechanical properties of the tiles produced. The properties were then compared with South African National ... -
Natural radioactivity levels and radiological hazard indices of soil and water collected from Kaserem limestone quarry, Kapchorwa district, Uganda
(Kyambogo University (un published work), 2017-10)This study was to determine the gamma ray concentration/activity due to naturally occurring radionuclides present in soil and water from Kaserem limestone quarry area in Kapchorwa District and the associated hazard ... -
Optical absorption and photoluminescence properties of Cucurbita maxima dye adsorption on TiO2 nanoparticles
(IOP Publishing Materials Research Express, 2023-04)Dye-sensitised solar cells (DSSCs) are 3rd generation photovoltaic device that imitate photosynthesis in plants. The fundamental concept of a DSSCs is that the photoanode is covered by the dye as a sensitiser. Natural dyes ... -
Optical activity and faraday effect in some mineral and vegetable oils.
(Makerere University (unpublished work), 2000-03)This Thesis presents results of a study of Optical Activity and Faraday Effect (OAFE) in some mineral and vegetable oils in the temperature range of 6°C to 45°C and magnetic field up to 140mT. Intrinsic birefringences ... -
Performance evaluation of amorphous silicon photovoltaic module using solar light of different wavelengths
(Kyambogo University[unpublished work], 2022-07)The performance of amorphous silicon photovoltaic module was evaluated using solar light of different wavelengths in this study. The different wavelengths of solar light were filtered by use of colour filters. During ... -
Performance of plastic-derived liquid fuel in a compression ignition engine
(Kyambogo University [unpublished work], 2023-09)Fossil fuels are the major sources of energy for running engines, powering industries, and for supporting domestic activities. However, as energy-intensive activities increase, there is a need for diverse sources of energy ... -
Radiological hazard levels by the gamma ray emitting naturally occurring radioisotopes in selected fish species of Lake Albert in Uganda
(Kyambogo University (un published work), 2017-10)A study was conducted for natural radioactivity in some fish samples from Lake Albert, shared by five riparian districts namely Ntoroko, Kibaale, Hoima, Buliisa and Nebbi, located in the western part of the great ... -
Radiological hazard levels due to gamma emmiting radionuclides in natural water bodies in selected sub-counties of Mubende district
(Kyambogo University [unpublished work], 2016-01)This study was carried out to investigate the health hazard levels due to gamma rays emitted by radionuclides in natural water bodies in selected sub-counties in Mubende District. Owing to the interaction between underground ... -
Specific activity levels of radionuclides in spring water, selected plants and soils along Nakivubo channel
(Kyambogo University[unpublished work], 2014-01)There is an increase in the number of industries that discharge their effluents into Nakivubo channel. It is possible that some of the industrial effluents may contain radioactive nuclides since they are widely used in ... -
Structural and mechanical properties of non-glazed ceramic tiles developed from selected mineral deposits in Uganda
(Nano-Horizons: Journal of Nanosciences and Nanotechnologies, 2023-07)Uganda is well endowed with clay resources; however, comprehensive knowledge about the composition, structure and suitability of these clays for ceramic tile production is lacking. In this study, we provide a ... -
Structure and optical absorption properties of dyes extracted from selected plant materials for dye sensitized solar cells
(Kyambogo University [unpublished work], 2023-11)Sunlight is a natural alternative renewable energy source to expensive hydroelectricity. Dye sensitized solar cells (DSSCs) are third generation solar cells which have the potential to significantly lower the cost associated ... -
A study of upland clay from ant-hills as a refractory material.
(Kyambogo University [unpublished work], 2016-01)This study was purposed to investigate the suitability of upland ant-hill clays for fabricating refractory bricks. The chemical composition of the anthill clay was determined using the Atomic Absorption Spectrophotometer ... -
Thermal conductivity of fired clay of varied mineral composition made from selected Uganda clay types
(Kyambogo University [unpublished work], 2016-01)The use of thermal insulators is one of the most important applications in thermal energy conservation systems. This study determined the effect of varying mineral compositions on thermal conductivity. Dry powders of kaolin, ...
