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 ... -
Generalization of a theorem of fitting on the product of two normal nilpotent subgroups of a group
(University of the Western Cape, 1977)Fitting proved that if H and K are normal nilpotent subgroups of G, then so is HK (t1 l'Hilfssatz 10, p. 100). The question arises if this result could be generalized to other group theoretical properties -
The determination of diffracted wave fields by an annulus according to Braunbek’s method
(University of the Western Cape, 1981)In this thesis a short wave approximation, the method oI W Braunbek, is used to determine the diffracted fields (acoustic and electromagnetic) of plane harmonic waves by an annular aperture. Integral representations ... -
A comparative study of degeneration of the posterior limbs and girdles of some scelotes species.
(University of the Western Cape, 1981)The genus Scelotes was instituted by Fitzinger in 1826 and is represented by nineteen species and subspecies in Southern Africa (Fitzsimons, 1943) . Valuable contributions have been made to our knowledge of the Lacertilia ... -

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 ... -
The effect of Nicotine exposure on aspects of liver Carbohydrate metabolism
(University of the Western Cape, 1989)The liver plays an important role in maintaining the blood glucose concentration. In this respect glycogenolysis and gluconeogenesis play an important role. Interference with these pathways may therefore have an effect on ... -
Population and Physiological Studies of selected Geophytics Species of Lowland Coastal Fynbos in the Southwestern Cape
(University of the Western Cape, 1990)Population and physiological studies were conducted in coastal fynbos in the South-western Cape. Minor ecophysiological studies were also conducted such as the soil moisture content and pH. Two species, viz. Haemanthus ... -
a comparative study of the influence of different copper concentrations on the growth, chemical composition and activities of certain copper containing enzymes in atriplex nummularia lindl. and a. vestita (thunb.) Aell.
(University of the Western Cape, 1990)The total amount of native copper in soil depends on the amount of copper in the parent material (Tisdale .et .al.1968). It is usually in greater concentration in the soil than in parent rock because of weathering of the ... -
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 ... -
A critical analysis of aspects pertaining to the teaching of the ecology section of the standard eight biology syllabus.
(University of the Western Cape, 1991)In this study an attempt has been made to investigate how the Ecology section (suitable for fostering awareness and concern for the environment) of the standard eight Biology syllabus is taught. Since fieldwork and ... -
Biomonitoring as a means to determine the pollution level in Stellenbosch
(University of the Western Cape, 1991)A pollution survey was done in Stellenbosch, along two transects. One was south-east and the north-east of the Oorrobrick brickfield the focal point of this study. Pine and Oak trees, chasman the leaves and lichens were ... -
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 ... -
Perceptions of first year Biology students at a college of education towards the relevance of population dynamics as prescribed for current biology syllabusses at matriculation level in South African schools
(University of the Western Cape, 1992)Throughout this research, an attempt has been made to assess the perceived relevance, if any, of the Population Dynamics topic of the standard ten Biology syllabus, especially of those standard ten pupils enrolling as ... -
Vegetation relationships of priority conservation sites on the Cape flats
(University of the Western Cape, 1992)The physical environment of the cape Frats is outlined. The plant communities of twenty-one priority conservation sites are classified. Twenty-five communities, grouped into 15 associations, 8 alliances, 4 orders, 2 ... -
Conjugacy classes of some projective linear groups
(University of the Western Cape, 1992)Given a finite set X of distinct symbols the symmetric group Sx and the alternating group Ax are obtained without further constructions. More interesting groups are contrived, however, by imposing a certain structure on ... -
(p.n.) Reactions on 59co in the intermediate energy range
(University of the Western Cape, 1992)Detailed theoretical investigations [Chi80,Mos82,Kle85] of (p,n) and (p,p') data indicate that the reaction mechanisms operative at intermediate energies and for energy losses up to several tens of MeV are predominantly ... -
