Chromium and Titanium based Stannum Nanocomposites materials as electron acceptors for next generation bulk Heterojunction photovoltaic cells
(University of the Western Cape, 2018)Renewable energy has become the centrepiece of research in resolving the energy crisis. One of the forms of renewable energy is solar energy. This form of energy is costly to develop. Organic molecules are promising materials ... -
Church and state relations in lesotho: a theological reflection on catholic and reformed contributions 1833-2007
(2013)The relationship between church and state in the history of the Kingdom of Lesotho is an important yet neglected study. This thesis explores how this relationship has played itself out with particular interest in ... -
Chytridiomycosis in amphibian populations in the Western Cape, South Africa
(University of the Western Cape, 2002)There have been many cases reported of amphibian populations declining. These are often due to anthropogenic factors such as habitat destruction and pollution. However, some declines have not had an obvious cause and many ... -
CIMT and cardiovascular risk in five-year-old children in a low socioeconomic population exposed to alcohol and nicotine during pregnancy: a case-control study
(University of the Western Cape, 2020)Cardiovascular diseases (CVD) are among the top 10 causes of death in all ages in South Africa. The prevalence of maternal smoking and alcohol consumption during pregnancy is alarmingly high in South Africa. In utero ... -
Circadian activity rhythms and early gene expression in the suprachiasmatic nucleus of a diurnal rodent, Rhabdomys pumilio
(UWC, 2001)Although humans are diurnal in behavior, animal models used for the study of circadian rhythms are mainly restricted to nocturnal rodents. This study focused on circadian behavior and gene expression in a diurnal rodent ... -
Citizen participation and water services delivery in Khayelitsha, Cape Town
(University of the Western Cape, 2011)This study analyses the relationship between the manner of citizens’ engagement with the state and the level of service delivery they experience in their everyday lives, as residents of Khayelitsha. The phenomena of so-called ... -
Cloning and characterization of the human coronavirus NL63 nucleocapsid protein
(University of the Western Cape, 2011)The human coronavirus NL63 was discovered in 2004 by a team of researchers in Amsterdam. Since its discovery it has been shown to have worldwide spread and affects mainly children, aged 0-5 years old, the immunocompromised ... -
Cloning and characterization of three compost metagenome-derived α‑L‑Arabinofuranosidases with differing thermal stabilities
(University of the Western Cape, 2014)Second generation biofuels production requires a suite of lignocellulolytic enzymes, acting synergistically to liberate the fermentable monosaccharides contained within agricultural waste materials. The use of thermostable ... -
Cloning and expression of human cyclophilin A and its interaction with human coronavirus NL63 nucleocapsid protein
(University of the Western Cape, 2011)Coronaviridae family is composed of a number of ribonucleic acid (RNA)-containing viruses currently classified into two genera, the coronavirus and torovirus. The family is classified together with the Arteviridae in the ... -
Cloning and expression of the M-gene from the human coronavirus NL-63 in different expression systems
(University of the Western Cape, 2008)Respiratory tract infections are one of the leading causes of morbidity and mortality across the world. This is especially true for infants, young children, the elderly and the immunocompromised. The strain placed on ... -
Cloning and sequence analysis of the gene coding for a Leuconostoe Bacteriocin
(University of the Western Cape, 1994)Previous studies have shown that Leuconostoc (Lc.) carnosum Tal la produces a bacteriocin that has been designated leucocin B-Tal la [Papathanasopoulos, 1993, M.Sc thesis, University of the Witwatersrandl. Leucocin B-Talla ... -
Cloning of Human Coronavirus NL-63 ORF3, M and E genes for antibody production
(University of the Western Cape, 2010)Human Coronavirus NL-63 is a respiratory virus with a high incidence rate, causing mild respiratory infections in children under the age of 18. The outbreak of Sever Acute Respiratory Syndrome (SARS) in 2003 sparked increased ... -
Cloning, expression and characterisation of Amidase Genes from a psychrotolerant Nesterenkonia isolate
(University of the Western Cape, 2009)A nitrile and amide hydrolysing Nesterenkonia sp. was isolated from Antarctic soil and was characterised as a psychrotolerant, halotolerant and alkaliphilic extremophile. Amidases are widely distributed in both prokaryotic ... -
Cloning, expression and characterization of Novel Lipase and Esterases from Burkholderia multivorans UWC10
(2005)An esterase and lipase producing Burkholderia multivorans strain was isolated by culture enrichment strategies. A shotgun library of Burkholderia multivorans genomic DNA (prepared in E. coli/pUC18) was screened for lipase ... -
A clustering smart phone users based on the digimiter survey and mobile application data

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 ... -
CO2 sequestration using brine impacted fly ash
(University of the Western Cape, 2009)Coal combustion accounts for over 40 % of the world's energy production and this figure is projected to increase with increasing human population and industrialization. The combustion of coal leads to the generation of ... -
CO2 sequestration using brine impacted fly fish
(University of the Western Cape, 2009)It was hypothesized that South African FA and brine could sequester CO2 through mineral carbonation. A statistical approach was undertaken to optimize the % CaCO3 formed from FA/brine/CO2 interaction with input parameters ... -
Coal fly ash and acid mine drainage based heterogeneous Fe catalysts Friedel-Crafts alkylation reaction
