The prevalence and survival of Campylobacter, Salmonella and Listeria species in poultry processing plant
(University of the Western Cape, 2004)The organisms in this study were chosen due to their associations with foods and their potential as food borne pathogens. Food borne diseases are an import public health problem in most countries. Bacteria of the genera ... -
The Prevalence of Members of the “Red Complex” in Pregnant Women as Revealed by PCR and BANA Hydrolysis.
(University of the Western Cape, 2005)Increased levels of oestrogen and progesterone during pregnancy may lead to periodontal disease. The anaerobic Gram-negative bacteria called red complex (Porphyromonas gingivalis, Tannerella forsythensis and Treponema ... -
Prevalence of uncontrolled hypertension and the pharmacogenomics of enalapril-induced adverse effects among patients in the Vhembe district
(University of the Western Cape, 2022)Controlling blood pressure (BP) among individuals with hypertension is important in the prevention of cardiovascular diseases (CVDs). However, maintaining optimal BP levels in individuals who are prone to drug-induced ... -
The prevalence, risk factors and serotypes of GBS in Libyan women at labour and the rate of vertical transmission of GBS from mother to infant
(University of the Western Cape, 2022)Group B Streptococcus (GBS) also known as Streptococcus agalactia, is one of the most important causes of serious neonatal infections. Early detection of GBS colonisation in the mother is thus of primary importance to ... -
Pricing American style employee stock options having GARCH effects
(University of the Western Cape, 2010)We investigate some simulation-based approaches for the valuing of the employee stock options. The mathematical models that deal with valuation of such options include the work of Jennergren and Naeslund [L.P Jennergren ... -
Pricing European options : a model-free approach
(University of the Western Cape, 2016)This paper focuses on the newly revived interest to model free approach in finance. Instead of postulating some probability measure it emerges in a form of an outer-measure. We review the behavior of a market stock price ... -
Pricing methods for Asian options
(2010)We present various methods of pricing Asian options. The methods include Monte Carlo simulations designed using control and antithetic variates, numerical solution of partial differential equation and using lower bounds.The ... -
Probing galaxy evolution below the noise threshold with radio observations
(University of the Western Cape, 2020)The faint radio population consisting of star forming galaxies (SFG) and radio-quiet active galactic nuclei (AGN) is important in the study of galaxy evolution. However, the bulk of the faint population is below the ... -
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 ... -
Probing the expansion history of the universe using upernovae and Baryon Acoustic Oscillations
(University of the Western Cape, 2016)The standard model of cosmology (the ɅCDM model) has been very successful and is compatible with all observational data up to now. However, it remains an important task to develop and apply null tests of this model. These ... -
Probing the large-scale structure of the universe with correlation functions
(University of the Western Cape, 2014)In this project we explore a new statistical package called KSTAT that computes the 2PCF and higher order correlation functions, such as the 3PCF, on BOSS, making use of high performance computing facilities to improve ... -
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 ... -
Processing hidden Markov models using recurrent neural networks for biological applications
(University of the Western Cape, 2013)In this thesis, we present a novel hybrid architecture by combining the most popular sequence recognition models such as Recurrent Neural Networks (RNNs) and Hidden Markov Models (HMMs). Though sequence recognition problems ... -
Production and evaluation of a TiO2 based 68Ge/68Ga generator
(University of the Western Cape, 2014)68Ge/68Ga generators rely on metal oxide, inorganic and organic sorbents in order to prepare radionuclides useful for clinical applications. The requirements for 68Ge/68Ga generators are that the 68Ga obtained from the ... -
Production of cytokines in human whole blood after incubation with the nucleocapsid protein of the NL63 Coronavirus
(University of the Western Cape, 2012-11)The Coronaviridae family consists of RNA viruses within the order Nidovirales. The family is classified into two genera, namely the corona- and toroviruses. Coronaviruses are enveloped, single stranded, positive sense ... -
