Teenage mothers’ reflections of their unintended, repeat pregnancies
(2013)Globally, teenage pregnancy remains a disturbing phenomenon which impacts on the lives of teenagers, their families and society as a whole. Numerous attempts at addressing the problem have seen a decline in fertility rates ... -
Testing Gravity with MeerKAT and the SKA
(University of the Western Cape, 2020)The new 64-dish radio telescope array MeerKAT will be absorbed into the international Square Kilometre Array (SKA) in late 2020s. These two telescope arrays will produce three-dimensional maps of the integrated intensity ... -
Testing gravity with redshift-space distortions, using MeerKAT and the SKA
(University of the Western Cape, 2019)The growth rate of large-scale structure is a key probe of gravity in the accelerating Universe. Standard models of Dark Energy within General Relativity predict essentially the same growth rate, whereas Modified Gravity ... -
Testing the statistical isotropy of the universe using radio survey data
(University of the Western Cape, 2019)The Cosmological Principle forms part of one of the most fundamental hypotheses of modern Cosmology. So it is very important to assess whether it holds true using observational data, or whether it consists of a mathematical ... -
A theoretical study of stellar pulsations in young brown dwarfs
(University of the Western Cape, 2011)This thesis reports the results of a twofold study on the recently proposed phenomenon of 'stellar pulsations' in young brown dwarfs by the seminal study of Palla and Baraffe (2005) (PB05, thereafter). The PB05 study ... -
A theoretical study of stellart pulsations in young brown dwarfs
(University of the Western Cape, 2011)This thesis reports the results of a twofold study on the recently proposed phenomenon of ‘stellar pulsations’ in young brown dwarfs by the seminal study of Palla and Baraffe (2005) (PB05, thereafter). The PB05 study ... -
Thermochromic properties of VO2 nano-coatings by inverted cylindrical magnetron sputtering
(University of the Western Cape, 2012)Vanadium dioxide (VO2) films have been known as the most feasible thermochromic nano-coatings for smart windows which self control the solar radiation and heat transfer for energy saving and comfort in houses and automotives. ... -
Three dimensional thermal modelling of high temperature proton exchange membrane fuel cells in a serpentine design
(University of the Western Cape, 2010)The aim of my work is to model a segment of a unit cell of a fuel cell stack using numerical methods which is classified as computational fluid dynamics and implementing the work in a commercial computational fluid dynamics ... -
Tin Catalyst preparation for Silicon Nanowire synthesis
(University of the Western Cape, 2018)Solar cells offer SA an additional energy source. While Si cells are abundantly available they are not at an optimal efficiency and the cost is still high. One technology that can enhance their performance is SiNW. ... -
Tin-oxide thin films by thermal oxidation
(University of Western Cape, 2021)Tin dioxide (SnO2) thin films are a worthy candidate for an electron transport layer (ETL) in perovskite solar cells, due to its suitable energy level, high electron mobility of 240 cm2 v-1 s- 1, desirable band gap of ... -
Triaxiality and rotational bands in 133ce
(University of Western Cape, 2021)The neutron-de cient nuclei between the N = 50 and N = 82 shell closures provide rich information on the shape and structure of the nucleus. The isotones of 133Ce and 131Ba (N = 75) lie in this region of the nuclear ... -
The use of FLUENT for heat flow studies of the hot-wire chemical vapor deposition system to determine the temperatures reached at the growing layer surface
(University of the Western Cape, 2009)The overall aim of this project is to study the heat transfer inside the reaction chamber of the Hot-Wire Chemical Vapor Deposition (HWCVD) system with a commercial software package FLUENT6.3; it is one of the most popular ... -
Using internet -enabled remote instrumentation for research and training in physics: Evaluation of different diffusion barriers for silver metallization
(University of the Western Cape, 2007)The growth of the Internet has led to many interesting developments for both educational and commercial purposes. In this project an attempt was made to use the Internet for a research purpose to facilitate the determination ... -
Validation of Gamma Ray spectrometry process used to determine the radionuclides and radioactivity levels in decorative Granite countertops.
(University of the Western Cape, 2016)Humans are continuously exposed to low level of ionizing radiation, sources include soil, medical treatment and as well as radiation emissions from natural materials like granite rocks. The radiation levels present in these ... -
Vertically aligned silicon nanowires synthesised by metal assisted chemical etching for photovoltaic applications
(University of the Western Cape, 2015)One-dimensional silicon nanowires (SiNWs) are promising building blocks for solar cells as they provide a controlled, vectorial transport route for photo-generated charge carriers in the device as well as providing ...
