Computational modelling of a hot-wire chemical vapour deposition reactor chamber
(University of Western Cape, 2020)In this thesis, I explore the subjects of fluid dynamics and the Hot-Wire Chemical Vapour Deposition (HWCVD) process. HWCVD, in its simplicity, is one of the more powerful and elegant deposition techniques available in ... -
Determination of natural radioactivity concentrations in soil: a comparative study of Windows and Full Spectrum Analysis
(University of the Western Cape, 2004)In this study, two methods of analysing activity concentrations of natural radionuclides (U, Th and K) in soil are critically compared. These are the Window Analysis (WA) and Full Spectrum Analysis (FSA). In the usual WA ... -
Disentangling star formation and AGN activity in the GAMA (G23) region
(University of the Western Cape, 2021)Observations of galaxies at di↵erent wavelengths have shaped our understanding of their formation and evolution through time. The commonly derived parameters, such as stellar mass and star formation rate (SFR), rely on ... -
Microwave synthesis of the Schiff base metal-ligand complexes with Cu and Ni centres
(University of Western Cape, 2021)Nitric oxide (NO) plays a vital role as a biological messenger in biological systems. However, NO detection and quantification have always posed significant complications. There is, therefore, a need to develop new materials ... -
Probing large-scale structure with the SKAO and other cosmological surveys
(University of the Western Cape, 2022)In recent history there have been several advances in cosmology, which has significantly shaped our understanding of the Universe. The current leading theory is called ΛCDM, which can successfully model the expansion of ... -
Radiation-induced Leukaemia in South Africa: Response of lymphocytes and cd34+ cells to different radiation qualities
(University of the Western Cape, 2020)Epidemiological studies have highlighted that leukaemia can be considered as the most prominent malignancy after radiation exposure during childhood. The lifetime risk on radiation-induced leukaemia for a given dose is 3 ... -
Radiometric study of soil: the systematic effects
(University of the Western Cape, 2007)The natural 238U, 232Th and 40K radioactive content of vineyard soil was measured with an in-situ gamma-ray detector. The activity concentrations measured with the in-situ detector are normalized using the laboratory-determined ... -
Radon exhalation studies for applications in low background environments.
(University of the Western Cape, 2022)Neutrinoless double beta decay (0 ) is a rare process that is yet to be observed. Observation of neutrinoless double beta decays would imply lepton number violation, and that the neutrino is its own antiparticle ... -
Radon in the Cango Caves
(University of the Western Cape, 2005)Radon is a naturally occurring radioactive element in the 238U decay series that is found in high concentrations in certain geological formations such as Caves. Exposure to high concentrations of radon has been positively ... -
Realising the right to the highest attainable standard of health in the nuclear industry
(University of the Western Cape, 2019)African states are interested in the development of nuclear power (also referred to as atomic power) for the generation of electricity and desalination. These include Algeria, Egypt, Ghana, Kenya, Morocco, Namibia, Niger, ...
