The synthesis, characterization and reactivity of some mononuclear hydrocarbyl compounds of iron
(University of the Western Cape, 1997)
Mononuclear hydrocarbyl compounds of the type LnM(CH2)nCH:CH2 (L"M : Cp*Fe(CO)2 and CpFe(CO)2, n: 2-4,6), Cp(CO)zFe(CH2)nOH (n : 4-6,8) and Cp*(CO)2Fe(CH2)+OH have been synthesized. All these compounds have been l3 fully ...
"Genetic variation between two subspecies of reedfrogs in the genus Hyperolius (Anura: Hyperoliidae)"
(University of the Western Cape, 1993)
H. m. broadleyi and H. m. verrucosus are not only different in terms of colour pattern, but distinct genetic differences were detected in restriction site maps of their ribosomal DNA. A sequence divergence value of 13,8% ...
Genetic variation of rana fuscigula in Southern Africa
(University of the Western Cape, 1994)
Naturalists have long been engaged in describing and explaining diversity in the biological world. The discovery of the molecular basis of inheritance has led to rapid increase in the use of biological macromolecules in ...
An exploration of the electrophysiological properties and ion transport across the isolated perfused seminiferous tubule of the rat
(UWC, 1999)
A knowledge ofthe transport of ions is fundamental to the understanding ofthe 'bloodtestis'
barrier and the transport of fluid across the seminiferous tubule. This is the first
study that has investigated the isolated ...
Pre-equilibrium cross section calculations with a realistic effective nucleon-nucleon interaction
(University of the Western Cape, 1995)
The principle aim of this work is to improve the way in which pre-equilibrium double differential
cross-sections are currently calculated [1, 2, 3, 4]. The theoretical basis for these
calculations is the Multistep Direct ...
In-service female teachers' anxieties about mathematics: a reflective study on mathematics classroom practice at a college of education
(UWC, 1994)
The incidence of mathematics anxiety manifesting itself in in-service college students is generally on the increase. Such anxiety does not only affect the mathematical performance of students but also their teaching of the ...
The synthesis of prodrugs and novel analogues of Beta-sympathomimetic bronchodilators
(University of the Western Cape, 1998)
Prodrugs are reversible derivatives of active drugs destined to undergo chemical or enzymatic transformation to the active drug after administration in order that the active drug may subsequently elicit the desired ...
Cross-sectional transmission electron microscopy of nickel silicide formation
(University of the Western Cape, 1993)
Silicides play a significant role in modern device technology. The operation of electronic devices heavily relies on the specific properties of metal-semiconductor interfaces. Although semiconductor technology has proven ...
The influence of maternal nicotine exposure on neonatal rat lung septal status
(University of the Western Cape, 1995)
The aim of this study was to determine the effect of maternal nicotine exposure on the status of rat lung alveolar septa of 1 to 2l day old offspring. Wistar dams were injected subcutaneously, using a dosage of 1 mg ...
The relationship between "fertilizaiton environment" and structure and physiology of selected Anuran Spermatozoa
(University of the Western Cape, 1993)
The propagation of species and modes of fertilization of higher vertebrates are aspects which have been extensively researched. Studies on the spermatology of lower vertebrates have not received the same attention. Anurans ...
