An investigation of the effects of donor age on some haematological characteristics of the Wistar rat (Rattus Norwegicus)
(University of the Western Cape, 1986)Knowledge of haematological 'normdata', of experimental animals, and the biological variables that affect it is essential in order to recognise variations from the normal. In addition, the haemopoietic system may be ... -
Seisoensfluktuasies in Industriële produksie en die Aandelemark met spesiale verwysing na die Suid - Afrikaanse situasie
(University of the Western Cape, 1991)In 1976 Rozeff and Kinney found that seasonality exists in the monthly rates of return on the New York Stock Exchange with peak periods in January. By making use of this information and the fact that the rates of return ... -
Prestasiemotivering by studente aan die Universiteit van Wes-Kaapland.
(University of the Western Cape, 1991)The major objective of this study was to investigate the nature of the relationship between achievement motivation, autonomous and social achievement values, study habits and attitudes, locus of control and socio-economic ... -
The effect of maternal nicotine exposure on rat lung tissue morphology. ' a light and electron microscopic study
(University of the Western Cape, 1991)The infants of women who smoke during pregnancy have a lower birth mass than those born of women who abstain. Animal studies reveal that reduced growth due to maternal nicotine exposure during gestation is accompanied by ... -
The influence of nicotine exposure on the male reproductive system
(University of the Western Cape, 1993)It is well documented that cigarette smoking and nicotine exposure create widespread physiological disorders in humans and animals. The primary tobacco constituent that is responsible for the toxicological consequences ... -
The effect of diet on the mucus histochemistry and adjacent histology of the digestive tract in Vervet monkeys.
(University of the Western Cape, 1993)There is a need for defined models of human nutritional disorders partly because serious misconceptions about models are common amongst researchers. Historically a large variety of species has been used including primates, ... -
The effect of maternal nicotine exposure on the quantity and quality of neonatal rat lung connective tissue
(University of the Western Cape, 1994)The infants of smoking mothers (compared to non-smoking mothers) have been shown to have a lower birth mass, a lower brain mass, an increased perinatal mortality rate as well as a predisposition to respiratory abnormalities ... -
Evaluation of quantitative motility and zona pellucida binding of human spermatozoa in an assisted reproductive programme
(University of the Western Cape, 1994)Male factor disorders affect more than 30% of infertile couples. Thus, it has become important to perform a andrological consultation and a basic semen evaluation in all male partners of couples consulting for infertility. ... -
Epidemiological study of Tuberculosis in Macassar camp
(University of the Western Cape, 1995)The aim of this study was to determine and evaluate the prevalence of TB infection, active TB cases and the risk factors associated with TB infection in Macassar Camp in Macassar (about 40 km from Cape Town on the False ... -
An investigation of the production of non-coated sustained release beads by extrusion and Spheronization
(University of the Western Cape, 1995)The popularity and increasing complexity of sustained release dosage forms has resulted in increased costs to the patient. One approach to achieve cheaper, yet effective, sustained release medication is through the ... -
Science text: Facilitating access to physiology through cognition-based reading intervention
(University of the Western Cape, 1995)Reading and understanding science text is the principal means by which students at tertiary level access scientific information and attain scientific literacy. However, understanding and learning from science texts require ... -
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 ... -
Synergistic use of promoter prediction algorithms: a choice of small training dataset?
(University of the Western Cape, 2000)Promoter detection, especially in prokaryotes, has always been an uphill task and may remain so, because of the many varieties of sigma factors employed by various organisms in transcription. The situation is made more ... -
New algorithms for EST clustering
(University of the Western Cape, 2000)Summary: Expressed sequence tag database is a rich and fast growing source of data for gene expression analysis and drug discovery. Clustering of raw EST data is a necessary step for further analysis and one of the most ... -
Oxidative fixation of dinitrogen by photocatalysis
(University of Western Cape, 2000)The heterogeneous photocatalytic oxidation of dinitrogen to nitrate, NO3 and/or nitrite, no2 using peroxy species of titanium (IV) in aqueous suspensions has been investigated. The photocatalysts used were titanium peroxide ... -
Novel genomic approaches for the identification of virulence genes and drug targets in pathogenic bacteria
(University of the Western Cape, 2001)While the many completely sequenced genomes of bacterial pathogens contain all the determinants of the host-pathogen interaction, and also every possible drug target and recombinant vaccine candidate, computational tools ... -
Generation of a human gene index and its application to disease candidacy
(University of the Western Cape, 2001)With easy access to technology to generate expressed sequence tags (ESTs), several groups have sequenced from thousands to several thousands of ESTs. These ESTs benefit from consolidation and organization to deliver ... -
Parameters affecting the production of fumonisin B1 by fusarium verticillioides in culture
(University of the Western Cape, 2001)Fi1sarium verticillioides is a very important mycotoxin-produeing fungus associated with maize. Fverticillioides produces a group of mycotoxins known as fumonisins under suitable environmental conditions. A series of studies ... -
Pharmacist educational outreach for improved primary care of asthma in children
(University of the Western Cape, 2001)Underdiagnosis and undertreatment of asthma in children are barriers to optimal health care delivery and health, incurring substantial costs to both the families and health services. A tailored multifaceted educational ... -
Low detection of exon skipping in mouse genes orthologous to human genes on chromosome 22
(University of the Western Cape, 2002)Alternative RNA splicing is one of the leading mechanisms contributing towards transcript and protein diversity. Several alternative splicing surveys have confirmed the frequent occurrence of exon skipping in human genes. ...
