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 ... -
Production of Li, Be and B nuclei in the interaction of 12C with 12C at incident energies of 200 and 400 MeV
(University of the Western Cape, 2008)The objective of this project is to study the production of Li, Be and B isotopes emitted in the interaction of 12C with 12C at incident energies of 200 and 400 MeV.The energies of these produced fragments were measured ... -
Profiling the French community in the Western Cape, South Africa : evidences from an innovative survey
(University of the Western Cape, 2016)In South Africa, demographics consequently play a prominent role in public policy and the country (rainbow nation) or often called a World in One Country, provide interesting interactions between the whites, coloured and ... -

Protection of Karst spring in Shanxi Region,China: A case study from Jinci Spring Catchment.
(University of Western Cape, 2019)Groundwater is an important of water resources and plays a significant role in the water supply in most parts of the world. It is also an important ecological environment factor, and its variations often affect natural ... -
Protein expression and antifungal effect of fluconazole-resistant Candida species following effective in vitro treatment with K21, a novel antifungal agent
(University of Western Cape, 2019)Background: Oropharyngeal candidiasis, caused by the fungus Candida, is the most common opportunistic infection affecting the quality of life of immunocompromised patients. Fluconazole is widely used as the first line ... -
Protein phosphatase biosensor for the detection of cyanotoxins associated with algal bloom
(2013)The toxicity of microcystin is associated with the inhibition of serine/threonine protein phosphatases 1 and 2A, which can lead to hepatocyte necrosis and haemorrhage. Analysis of microcystin is most commonly carried out ... -
Proteome profiling as tool to determine the effectiveness of traditional Africa therapies for Type 2 diabetes mellitus
(University of the Western Cape, 2022)Type 2 diabetes mellitus (T2DM) involves multiple organ dysfunction accompanied by a chronic inflammatory state and oxidative stress resulting from a combination of factors such as hyperglycaemia and dyslipidaemia. Although ... -
Proteome signature of breast cancer cells treated with fucoidan
(University of the Western Cape, 2016)Breast cancer is responsible for a large portion of cancer-related deaths. Worldwide, incidence is increasing. Routinely-used treatments for breast cancer are invasive and are associated with a range of side-effects which ... -
A proteomic analysis of drought and salt stress responsive proteins of different sorghum varieties
(University of the Western Cape, 2009)This study reports on a proteomic analysis of sorghum proteomes in response to salt and hyperosmotic stresses. Two-dimensional gel electrophoresis (2DE) in combination with mass spectrometry (MS) was used to separate, ... -
