  1. Non-lysosomal protein degrading systems in chicken skeletal muscle
    Arnold, Jane Elizabeth, 2017-12-11T14:17:06Z, University of Cape Town
    In an attempt to understand the roles played by the ubiquitin-dependent and calpain pathways in protein degradation in chicken skeletal muscles, biochemical studies were conducted on components of these two systems as well as their potential endogenous and exogenous substrates. ATP- and ubiquitin-de ...
  2. Vascular endothelial cell-surface proteoglycans
    Hiss, Donavon C, 2017-12-11T14:18:02Z, University of Cape Town
    A predominant species of heparan sulfate proteoglycan that consisted of at least two subunits linked by disulfide bonding was isolated from cell layers of normal ("cobblestone") bovine vascular endothelial cells in culture. Treatment of the parent molecules with dithiothreitol caused their complete ...
  3. A situation analysis of street children in Harare, Zimbabwe
    Pascoe, Margaret Joy, 2017-12-11T14:18:33Z, University of Cape Town
    The problem of children on the streets of Harare has been increasing over the last five years. The majority of these children appear to be of school-going age. Who are these children? Where do they live? Why are they not attending school? This study is an attempt to provide answers for these questio ...
  4. Small and medium enterprise financing and credit rationing: the role of banks in South Africa
    Mutezo, Ashley Teedzwi, 2017-12-11T15:17:28Z
    The potential of small and medium enterprises (SMEs) in promoting economic growth in both developed and developing countries is widely accepted and documented by both scholars and policy makers. Particularly lacking are studies on the evidence in support of the importance of credit rationing to the ...
  5. Some aspects of the nitrogen nutrition and growth of Gracilaria gracilis grown by suspended cultivation in Saldanha Bay, South Africa
    Wilson, Daniel T, 2017-12-08T05:50:43Z, University of Cape Town
    For suspended cultivation of seaweeds in the open ocean, the selection of suitable sites and the optimization of cultivation methods for maximum productivity are of utmost importance. Growth of raft-cultivated Gracilaria gracilis in Saldanha Bay is known to be badly affected in late summer due to th ...
  6. Variation in Thamnocortus insignis - genetically and environmentally plastic?
    Mgidi, Theresa Nobuhle, 2017-12-08T05:55:53Z, University of Cape Town
    Environmental variation of Thamnocortus insignis Mast. (Restionaceae) is presented, by using average dry weight measurements of six populations of this species found along the coast of the Cape Province. The dry weight measurements were used to detect variation in the growth rates of the six populat ...
  7. Species limits in the Rhodocoma gigantea (Kunth) Linder complex
    Mafa, Paseka, 2017-12-08T06:02:26Z, University of Cape Town
    Rhodocoma gigantea and Rhodocoma foliosus have been recognised by earlier authors as separate species on the basis of perianth length and shape. Linder (1985) superficially lumped these two species under Rhodocoma gigantea arguing that the difference between the two appear to be brought by ecologica ...
  8. Does the implementation of a closed fishing season during the breeding season benefit a species? : a per-recruit-based approach using Cymbula granatina as an illustration
    Govender, Anesh ;Arendse, Clement, 2017-12-08T06:08:27Z, University of Cape Town
    Closed seasons are generally implemented on the presumption that they increase reproductive output of fished populations. This is based on the assumption that the imposition of a closed season during the breeding season allows more individuals to reproduce, as they are not being harvested. I evaluat ...
  9. On the phylogenetic relationship of South African species of Cladophora (Chlorophyta) based on the 26S (LSU) gene region
    Arendse, Clement, 2017-12-08T06:21:26Z, University of Cape Town
    In order to delineate the genus Cladophora in South Africa, several sites along the Cape peninsula were sampled and sequences for the partial26S region of the rRNA were obtained and a phylogram was constructed. The aims of this study were to provide a robust phylogenetic tree describing the relat ...
