A study of the problems and possibilities of using the marine intertidal zone for teaching principles of ecology in senior secondary schools: A survey of biology teachers in the western cape.
(University of the Western Cape, 1994)In this study I investigate the attitudes of a group biology teachers in the Western Cape, to using the marine intertidal zone for teaching principles of ecology in senior secondary schools, by exploring the problems ... -
Investigation into the role of DWNN in cell death
(University of the Western Cape, 2004)Many genes are activated to influence the self-destruction programme of the cell. This programme entails synchronised instigation and implementation of numerous subprograms. The arrival of gene targeting aided in the ... -
The genease activity of mung bean nuclease: fact or fiction?
(University of the Western Cape, 2004)The action of Mung Bean Nuclease (MBN) on DNA makes it possible to clone intact gene fragments from genes of the malaria parasite, Plasmodium. This “genease” activity has provided a foundation for further ... -
Microbial diversity of Antarctic Dry Valley mineral soil
(University of the Western Cape, 2004)Antarctica provides some of the most extreme environments on earth. Low temperatures, low water availability and nutrient deficiency are contributing factors to the limited colonisation of Antarctic biotopes, particularly ... -
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 ... -
Human testis angiotensin-converting enzyme: crystal structure of a glycosylation mutant and investigation of a putative hinge-mechanism by normal mode analysis
(University of the Western Cape, 2004)Human angiotensin-converting enzyme (ACE) is a key enzyme in the regulation of blood pressure via the renin-angiotensin and kallikrein-kinin systems. A number of orally active drugs have been developed over the years ... -
Recombinant expression of the pRb- and p53-interacting domains from the human RBBP6 protein for in vitro binding studies
(University of the Western Cape, 2004)This thesis describes the cloning and recombinant expression of domains from the human RBBP6 protein for future in vitro binding studies with pRb and p53. RBBP6 is a splicing-associated protein that is known to interact ... -
Recombinant expression of the pRb- and p53-interacting domains from the human RBBP6 protein for in vitro binding studies
(University of the Western Cape, 2004)This thesis describes the cloning and recombinant expression of domains from the human RBBP6 protein for future in vitro binding studies with pRb and p53. RBBP6 is a splicing-associated protein that is known to interact ... -
Ancient Genes in Cancer Gene Expression?
(University of the Western Cape, 2004)Backsround: The Cancer/testis (CT) antigens are a division of germ cell specific genes not expressed in somatic cells, exceptions being placental cells and 20Vo - 4OVo of cancer types. The aptitude of CT antigens to elicit ... -
Isolation and identification of PNP-A homologues from Xerophyta viscosa Baker
(University of the Western Cape, 2004)Maintenance of growth, development and normal physiological processes remains crucial for the survival of plants. Plant hormones are described as integrators of external signal and internal developmental process in plants. ... -
An investigation of the plants used medicinally In self-care in the Bredasdorp / Elim region
(University of the Western Cape, 2004)Much of the traditional medicinal plant knowledge is to a large extent known by the older generations. This knowledge is at risk of disappearing due to not being passed down to younger members of the respective families ... -
The evaluation of Y-STR loci for use in forensics
(University of the Western Cape, 2005)The aim of this study was to investigate the forensic usefulness of various Y-chromosome short tandem repeat loci among South African sub-populations. Three different sets of Y-chromosome short tandem repeat loci were ... -
Microbiology of fly ash-acid mine drainage co-disposal processes
(University of the Western Cape, 2005)The waste products acid mine drainage formed during coal mining and fly ash from coal burning power generation, pose substantial environmental and economic problems for South Africa. Eskom has developed a remediation system ... -
Recombinant expression and full backbone assignment of the human DWNN using heteronuclear NMR
(University of the Western Cape, 2005)The cellular levels of a number of proteins have been found to be regulated by the ubiquitin-proteasome pathway. In this pathway, proteins are covalently tagged (“ubiquitinated”) by ubiquitin, which acts as a signal for ... -
Developing a generic hazard analysis critical control point (HACCP) system for the wheat milling industry
(University of the Western Cape, 2005)In South Africa there is a need within the milling industry for controlling food safety especially due to customer's demands and government's regulations. The best way to ensure food safety is with the implementation of a ... -
Exploring diversity and ecology of nonarchaea in hydrothermal biotopes
(University of the Western Cape, 2005)The Nanoarchaeota were proposed as the fourth archaeal sub-division in 2002, and the only fully characterized nanoarchaeon was found to exist in a symbiotic association with the crenarchaeote, Ignicoccus sp. This nanoarchaeote, ... -
The microbial composition of a natural methanogenic consortium
(University of the Western Cape, 2005)Wetlands account for approximately 20% of annual global methane emissions. Many wetlands receive inputs of organic matter, nutrients, metals and various toxic compounds from adjacent agricultural and industrial areas. The ... -
Physiological and cellular characterization of a plant natriuretic peptide
(University of the Western Cape, 2005)Plants in the field are exposed to multiple stresses and their response to these various stresses determines their capacity to survive. Plants can use multiple signaling pathways and signals to mediate their response; for ... -
Analysis of ammonia-oxidizing bacteria associated with the roots of Proteaceae plant species in soils of Fynbos ecosystem
(University of the Western Cape, 2005)The major objective of this study was to investigate soil ammonia-oxidizing bacterial diversity and composition associated with plant roots of Proteaceae plants and to compare it with non-plant associated soil. -
Investigation of the interaction of ceramide and acyl-coenzyme A with the mitochondrial associated protein, endozepine, using heteronuclear NMR
(University of the Western Cape, 2005)Endozepine is an alternative name for the testis-specific isoform of the acyl-CoA binding protein (t-ACBP). Acyl-CoA binding proteins form a highly conserved family of proteins, which bind long chain fatty acid esters with ...
