"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 ...
Student experiences of life science practicals
(UWC, 2001)
Science Educationists seem to agree that practical work should form an important component of any science course. Many students arrive at University without having been exposed to any practical work, while others were ...
Circadian activity rhythms and early gene expression in the suprachiasmatic nucleus of a diurnal rodent, Rhabdomys pumilio
(UWC, 2001)
Although humans are diurnal in behavior, animal models used for the study of circadian rhythms are mainly restricted to nocturnal rodents. This study focused on circadian behavior and gene expression in a diurnal rodent ...
The influence of maternal nicotine exposure on neonatal rat trachea development and alveoli status
(University of the Western Cape, 2000)
The aim of this study was to determine the effect of maternal nicotine exposure on
the status of the rat tracheal development as well as the rat lung of 7 to 42 day old
offspring. Wistar dams were injected subcutaneously, ...
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 ...
Ecology and conservation of high altitude amphibians
(UWC, 2002)
This study looked at the breeding ecology of the anurans, found in the Landdroskop mountain range in Grabouw, and some recommendations as to their conservation are made. There is very little known about the frogs in South ...
Block Toeplitz operators with rational symbols and discrete singular systems
(University of the Western Cape, 2001)
This thesis concerns block Toeplitz operators (equations). Consider the block
Toeplitz operator T = [<I> k-j ]k,j=O' where the <I>k are complex m x m matrices such
that

The norm in (0.1) is the usual ...
Long short-term memory recurrent neural networks for signature verification
(UWC, 2003)
Handwritten signature verification is defined as the classification process that strives to learn the manner in which an individual makes use of the muscular memory of their hands, fingers, and wrist to reproduce a signature. ...
Maximal left ideals and idealizers in matrix rings
(University pf Stellenbosch, 1984)
In this chapter we supply all the necessary definitions as
well as the required results needed in this work. All the
notation and terminology will also be explained carefully.
