Inleiding tot die eksperimentele Sielkunde
(University of the Western Cape, 1948)Elke skolier wat rue tevrede is om dit op skool slegs met lepels in te kry nie, het seker al gewonder hoe kennis oorspronklik verkry word. In daardie stadium is ons gewoonlik nog tevrede om die feite wat die onderwyser aan ... -
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 ... -
Investigation of the mechanism of fenfluramine-induced pulmonary phospholipidosis in the rat lung model
(University of the Western Cape, 1993)The aim of this study was to investigate the mechanism of fenfluramine-induced pulmonary phospholipidosis, by comparing the profile and levels of induced phospholipids in the rat and the mode of phospholipase inactivation, ... -
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, ... -
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. ... -
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 ... -
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 ... -
Site selection and community participation in the development of Gracilaria Gracilts (stackhouse) steentoft, irvine and farnham mariculture in the Western Cape province, South Africa.
(University of the Western Cape, 1999)The seaweed Gracilaria gracilis has been shown in previous studies to have potential for mariculture along the West Coast of South Africa. However, the selection of suitable sites is crucial for the success of a farming ... -
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 ... -
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 ... -
Synergistic use of promoter prediction algorithms: A choice for small training dataset?
(University of the Western Cape, 2000)This chapter outlines basic gene structure and how gene structure is related to promoter structure in both prokaryotes and eukaryotes and their transcription machinery. An in-depth discussion is given on variations types ... -
New Algorithms for EST clustering
(University of the Western Cape, 2000)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 challenging ... -
