  1. Molecular characterisation of the chaperone properties of Plasmodium falciparum heat shock protein 70
    Shonhai, A., 2007
    Heat shock protein 70 (called DnaK in prokaryotes) is one of the most prominent groups of chaperones whose role is to prevent and reverse protein misfolding. PfHsp70 is a heatinducible cytoplasm/nuclear localised Plasmodium falciparum Hsp70. PfHsp70 is thought to confer chaperone cytoprotection to P ...
  2. A model for a context aware machine-based personal memory manager and its implementation using a visual programming environment
    Tsegaye, M.E., 2007
    Memory is a part of cognition. It is essential for an individual to function normally in society. It encompasses an individual"s lifetime experience, thus defining his identity. This thesis develops the concept of a machine-based personal memory manager which captures and manages an individual"s day ...
  3. Population structure, growth and recruitment of two exploited infralittoral molluscs (Haliotis midae and Turbo sarmaticus) along the south east coast, South Africa
    Proudfoot, L.-A., 2007
    The two most frequently exploited species along the south east coast of South Africa are the gastropods, Haliotis midae (abalone) and Turbo sarmaticus (alikreukel). H. midae is a high valued commercial species, and suffers intense levels of illegal fishing. T. sarmaticus however, has no commercial v ...
  4. Regulation of hyu gene expression in Agrobacterium tumefaciens strains RU-AE01 and RU-OR
    Jiwaji, M., 2007
    Several Agrobacterium tumefaciens strains have been isolated for their ability to produce D-amino acids from D, L-substituted hydantoins. The optically pure D-amino acids are used in the synthesis of pharmaceuticals, as food additives and as insecticides. This hydrolysis of D, L-substituted hydantoi ...
  5. Institutional change and ecosystem dynamics in the communal areas around Mt Coke State Forest, Eastern Cape, South Africa
    Cundill, G., 2005
    Through a combination of theoretical discussion and case study analysis from two villages in the Eastern Cape Province, South Africa, this thesis explores the relationship between institutional change and ecosystem dynamics through a multi-scale approach that combines local and scientific knowledge. ...
  6. Food gardens, environmental lesson planning and active learning in the life orientation learning area - foundation phase : a case study at Lungelolethu Lower and Higher Primary School
    Ncula, N.S., 2007
    This study was conducted at Lungelolethu Lower/Higher Primary School in Keiskammahoek at a time when I was struggling to understand and implement the new South African curriculum policy, particularly in the Foundation Phase Life Skills Learning Programme. The research focused on my developing an und ...
  7. Towards a new approach for coastal governance with an assessment of the Plettenberg Bay nearshore linefisheries
    Smith, M.K.S., 2006
    Under the guidance of the new coastal management policies within South Africa this thesis advocates a more integrated, co-operative approach to local coastal management. The project aimed to acquire baseline information on the local nearshore fishery and resource state and to propose a set of indica ...
  8. An appraisal of the impact of the Fast Track Land Reform Programme on land use practices, livelihoods and the natural environment at three study areas in Kadoma District, Zimbabwe
    Chigumira, E.C., 2006
    This research appraises the impact of the Fast Track Land Reform Programme at three resettled communities in Kadoma District, Zimbabwe. In particular it assesses the livelihood practices of land recipients and their effects on the natural environment. Two of the communities, Lanteglos and CC Molina ...
  9. The role of aardvarks (Orycteropus afer) as ecosystem engineers in arid and semi-arid landscapes of South Africa
    Whittington-Jones, G.M., 2007
    Arid and semi arid environments are characterised by extreme fluctuations in temperature and low rainfall which present significant challenges to the animals inhabiting these areas. Mammals, such as aardvarks (Orycteropus afer, Pallas 1766), excavate burrows in order to avoid predators and climatic ...
  10. Spermiogenesis, sperm ultrastructure and reproductive tract morphology in cicadas : implications for systematic relationships
    Chawanji, A.S., 2007
    Sperm structure in five species of cicadine cicadas (Albanycada albigera, Azanicada zuluensis, Platypleura capensis, P. hirtipennis and Pycna semiclara) and five species of cicadettine cicadas (Melampsalta leucoptera, Quintilia walkeri, Stagira simplex, Xosopsaltria thunbergi and Monomatapa matoposa ...
