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)
(University of the Western Cape, 2005)This study sought to identify and fit the appropriate extreme value distribution to flood data, using the method of maximum likelihood. To examine the uncertainty of the estimated parameters and evaluate the goodness of ... -
Flood alleviation and restoration on the Lourens river, Somerset west, South Africa
(University of Western Cape, 2021)Somerset West and Strand in the Western Cape, South Africa, were developed on the Lourens River floodplain. This hardened the catchment and reduced the capacity of the river to transport and store floodwaters. The result ... -
Food resources available to juvenile fish (particularly rhabdosargus holubi) in seagrass beds of the swartkops etuary
(University of the Western Cape, 2023)Estuarine habitats are critical nursery areas for many species of marine fishes during their early life stages in terms of food availability and structural complexity, which increases survival and growth rates. The Cape ... -
Foraging ecology of Naja nivea and Dispholidus typus
(University of the Western Cape, 2019)It is widely reported that snakes can be major predators of avian nests, but the use of a single avian prey type by competing species has rarely been examined. This study aimed to investigate predation of a single food ... -
Foraminiferal biostratigraphic studies from Mesozoic succession of selected wells from the Orange Basin, western offshore, South Africa
(University of the Western Cape, 2020)Located on the western offshore on the Atlantic Ocean margin of Southern Africa, the Orange Basin is the youngest and largest of the South Africa’s seven sedimentary basins. This passive margin basin in known for its ... -
Foraminiferal biostratigraphy and depositional environment of the early cretaceous drilled succession in Durban basin, east coast, South Africa
(South African Journal of Higher Education, 2020)Durban Basin located on the eastern coast of South Africa has been a focus of interest for Petroleum Exploration for the last few decades. Only four exploratory wells have been drilled in this offshore basin without success. ... -

Foreign Exchange Option Valuation under Stochastic Volatility
(University of the Western Cape, 2009)The case of pricing options under constant volatility has been common practise for decades. Yet market data proves that the volatility is a stochastic phenomenon, this is evident in longer duration instruments in which the ... -
A forensic analysis of genetic variation in the Botswana population
(University of the Western cape, 2016)This thesis has been placed under a long term embargo. Forensic and population genetic parameters were investigated in the Botswana population using autosomal and Y-chromosome short tandem repeat markers. AmpFlSTR Profiler ... -
Forensic identification of six of Tanzanian populations using the extended haplotype markers
(University of the Western Cape, 2011)The aim of the present study was to evaluate the power of discrimination and genetic (diversity) parameters in the Y chromosome extended haploytpe markers in populations of Tanzania for forensic and populations studies. ... -
A forgotten diaspora : forced Indian Migration to the Cape Colony, 1658 to 1834
(University of the Western Cape, 2015)This thesis aims to explore Indian forced migration to the Cape Colony from 1658 to 1834. The forgotten diaspora‘ of its title refers to the first Indians who had come to the shores of South Africa, long before the ... -
Formation evaluation and assessment of flow units of some selected wells in the Bredasdorp basin, offshore South Africa
(University of the Western Cape, 2022)Petroleum geologists have long recognized the need to apply secondary and tertiary hydrocarbon recovery techniques for an accurate understanding of the internal architecture of a reservoir. The approach to effective ... -
Formation evaluation of deep-water reservoirs in the 13A and 14A sequences of the Central Bredasdorp Basin, offshore South Africa
(University of the Western Cape, 2014)The goal of this study is to enhance the evaluation of subsurface reservoirs by improving the prediction of petrophysical parameters through the integration of wireline logs and core measurements. Formation evaluations of ... -
The formulation and characterisation of corticosteroid loaded Ethosomes for topical delivery
(University of the Western Cape, 2020)Background/Introduction: Atopic dermatitis (AD) is one of the most prevalent diseases worldwide. It is a rapidly growing field of study with several research avenues to explore its pathophysiology and to find innovative ... -
The formulation and evaluation of indomethacin tablets
(University of the Western Cape, 1998)The overall objective of this research is to attempt to produce, by direct compression, indomethacin tablets which have good dissolution characteristics and an improved bioavailability profile, when compared to the capsule ... -
Formulation and evaluation of polymeric micelles for improved oral delivery of tenofovir disoproxil fumarate and zidovudine using poly-lactic-co-glycolic acid nanoparticles
(University of the Western Cape, 2018)Background: Tenofovir disoproxil fumarate (TDF) and Zidovudine (AZT) are both nucleotide and nucleoside analogue reverse transcriptase inhibitors (NtRTIs and NRTIs), respectively. They are used for the management and ... -
The formulation and evaluation of rapid release tablets manufactured from Artemisia Afra plant material
