The fate and transport of carbon-based nanomaterials in the environment
(University of Western Cape, 2020)The interest in carbon-based nanomaterials, such as carbon-nanodots and graphene, has grown exponentially because these materials have unique properties and applications in the medical, electronic, clean energy and several ... -
The fate of microbial contaminants in the subsurface with a South African case study
(University of the Western Cape, 2009)The time bound agenda of the Millennium Development Goals (MDG's) aims at reducing poverty, extending gender equality and advancing opportunities for health and education by addressing current and future water resource and ... -
Fatty acids as cancer preventive tools in the dietary modulation of altered lipid profiles associated with hepatocarcinogenesis
(University of the Western Cape, 2005)This thesis consists of a brief description on cancer, carcinogenesis, the changes in the type and level of dietary fat available in our diets over time and association with the development of certain diseases. The main ... -
The feasibility of high resolution, three-dimensional reconstruction of metal-coated surfaces in structural biology
(2006)Life is an emergent property of a complex network of interacting cellular-machines. Three-dimensional (3D), cellular structure captured at supra-atomic resolution has the potential to revolutionise our understanding of the ... -
Feasibility of Nuclear Plasma Interaction studies with the Activation Technique
(University of the Western Cape, 2018)Electron-mediated nuclear plasma interactions (NPIs), such as Nuclear Excitation by Electron Capture (NEEC) or Transition (NEET), can have a signi cant impact on nuclear cross sections in High Energy Density Plasmas (HEDPs). ... -

Female genital mutilation in Africa :what will encourage its discontinuation
(University of the Western Cape, 2009)Between one hundred and one hundred and forty million young girls around the world have reportedly been subjected to some form of genital excision during 2005. Approximately three million young girls are at risk every year ... -
Female migration and housing in South Africa: evidence from the 2007 community survey
(University of the Western Cape, 2013)Throughout the world, growing evidence suggests an increase of female migrants in migration streams. In the context of South Africa, women are not exempted from migration mechanisms. This new migration phenomenon is observed ... -
Female unemployment in South Africa: insight from the 2021 labour force survey.
(University of the Western Cape, 2023)The study focused on female unemployment and aimed to establish whether or not there is a relationship between female unemployment and demographic characteristics, whether the currently unemployed have ever worked or not, ... -
Female-male differentials in earning in South Africa: a comparative socio-demographic approach using data from Labour Force of 2007 and 2011
(University of the Western Cape, 2014)The study examines female-male differentials in earnings and factors associated with them within the labour market of South Africa. Dating back from the end of apartheid in 1994, a few labour policies have been implemented ... -
Fertility in Nigeria and Guinea : a comparative study of trends and determinants
(University of the Western Cape, 2011)The present study was conceived to examine the trend and factors affecting fertility in Nigeria and Guinea. Fertility has declined by about nineteen percent in Nigeria between 1982 and 1999. In the same period it has ... -
Fertility in Rwanda: Impact of genocide, an ananlysis of fertility before, during and after 1994 genocide
(University of the Western Cape, 2006)The 20th century has witnessed several wars and genocides worldwide. Notable examples include the Armenian and Jews genocides which took place during World War I and World War II respectively. The Rwandan genocide of 1994 ... -
Fertility trends and determinants among women of childbearing age (15-49): A comparative study of South Africa and Kenya
(University of the Western Cape, 2022)Fertility behavior in women plays a vital role in society. Fertility, mortality and migration are directly related to the population growth in society and its performance. Fertility refers to births by women in the ... -
Filament carburization during the hot-wire chemical vapour deposition of carbon nanotubes
(University of the Western Cape, 2008)This study reports on the changes in the structural properties of a tungsten-filament when exposed to a methane / hydrogen ambient for different durations at various filament-temperatures. -
Fischer-clifford matrices and character tables of inertia groups of maximal subgroups of finite simple groups of extension type
(University of the Western Cape, 2011)The aim of this dissertation is to calculate character tables of group extensions. There are several well–developed methods for calculating the character tables of group extensions. In this dissertation we study the method ... -
Fitted numerical methods to solve di erential models describing unsteady magneto-hydrodynamic ow
(2013)In this thesis, we consider some nonlinear di erential models that govern unsteady magneto-hydrodynamic convective ow and mass transfer of viscous, incompressible, electrically conducting uid past a porous plate ... -
Fitting extreme value distributions to the Zambezi river flood water levels recorded at Katima Mulilo in Namibia
(University of the Western Cape, 2005)The aim of this research project was to estimate parameters for the distribution of annual maximum flood levels for the Zambezi River at Katima Mulilo. The estimation of parameters was done by using the maximum likelihood ... -
Fitting extreme value distributions to the Zambezi River flood water levels recorded at Katima Mulilo in Namibia (1965-2003)
