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 ...
Optical properties of annealed hydrogenated amorphous silicon nitride (a-SiNx:H) thin films for photovoltaic application
(2013)
Technological advancement has created a market for large area electronics such as
solar cells and thin film transistors (TFT’s). Such devices now play an important
role in modern society. Various types of conducting, ...
Luminous red galaxies in simulations
(2010)
There have been a number of attempts to measure the expansion rate of the Universe using age-dating of Luminous Red Galaxies (LRGs).Assuming stars in LRGs form at the same time, age-dating of two populations of LRGs at ...
Radon escape from water
(University of the Western Cape, 2010)
This thesis aims to measure the rate of radon loss from water in a systematic way. The dependence on surface area, temperature and concentration will be investigated. The experiments were done at UWC by creating radon using ...
Clustering studies of radio-selected galaxies
(University of the Western Cape, 2011)
We investigate the clustering of HI-selected galaxies in the ALFALFA survey and compare results with those obtained for HIPASS. Measurements of the angular correlation function and the inferred 3D-clustering are compared ...
Probing the primordial Universe using the SKA in combination with other cosmological surveys
(University of the Western Cape, 2019)
Next-generation surveys of the large-scale structure of the Universe will be of great
importance in allowing us to extract invaluable information about the nature of the
Universe and the physical laws that govern it, at ...
Simulating the neutral hydrogen distribution during cosmic reionization
(University of the Western Cape, 2018)
We improve on the physical treatment of ionising source and sink populations
in the large scale semi-numerical simulations by implementing new physically
motivated parametrizations taken from high-resolution radiative ...
Post-deposition doping of silicon nanowires
(University of the Western Cape, 2018)
Silicon nanowires (Si NWs) continue to demonstrate superior properties to their bulk
counterparts, with respect to their morphological and electrical transport properties for
the use in photovoltaic (PV) applications. ...
The observed bispectrum for SKA and other galaxy surveys
(University of the Western Cape, 2019)
Next-generation galaxy surveys will usher in a new era of high precision cosmology.
They will increasingly rely on the galaxy bispectrum to provide improved constraints
on the key parameters of a cosmological model to ...
Radon exhalation of building materials
(University of the Western Cape, 2018)
Public concern about all radiation and radon exhalation from building
materials has been highlighted recently. The purpose of this study is
to address this public concern and to investigate the contribution of
building ...
