  1. Studies of the environmental and endocrine control of reproduction in the four striped field mouse, Rhabdomys pumilio
    Jackson, Claire, 2003
    Previous studies of the control of reproduction in Rhabdomys pumilio have shown that day length alone does not inhibit spermatogenesis, that a reduction in food availability and ambient temperature results in an inhibition of gametogenesis, that females are more susceptible to inhibition than are ma ...
  2. Isolation of antigenic peptides of Cowdria ruminantium and their encoding genes using a genome-derived phage display library
    Fehrsen, Jeanni, 2003
    The development of new and effective vaccines and immunodiagnostic reagents requires the characterisation of antigenically relevant proteins and their interactions with the products of the immune system. Phage display technology was investigated as a means of elucidating some of the antigenic proper ...
  3. Plastochron index - an indicator of plant structure and function : a case study using Pisum sativum L.
    Ade-Ademilua, O.E., 2006
    The use of chronological age for example, using days after sowing (DAS), or days after germination (DAG) as a time variable may result in the inherent variability between plants resulting in differences which can be large enough to obscure subtle developmental trends that become evident among plants ...
  4. Design, synthesis and evaluation of silver-specific ligands
    Daubinet, André, 2001
    Several series of ligands, designed to chelate silver(I) specifically in the presence of base metals, have been synthesised. The ligands include: - dithiodiamide compounds, prepared by the condensation of acetanilide derivatives with 1,2-dibromoethane; propanenitrile and propanoic ester derivatives ...
  5. Rural livelihoods at Dwesa/Cwebe : poverty, development and natural resource use on the Wild Coast, South Africa
    Timmermans, Herman Gerald, 2004
    This thesis uses the sustainable rural livelihoods framework to investigate the livelihoods of communities residing adjacent to a remote protected area on the Wild Coast. The communities living in the area are among the poorest in South Africa and are largely dependent on migrant remittances and sta ...
  6. Design of a performance evaluation tool for multimedia databases with special reference to Oracle
    Stakemire, Tonia, 2004
    Increased production and use of multimedia data has led to the development of a more advanced Database Management System (DBMS), like an Object Relational Database Management System (ORDBMS). These advanced databases are necessitated by the complexity in structure and the functionality required by m ...
  7. A phenomenological investigation into undergraduate students" experience of acquiring the discourse of engineering
    Van Heerden, K.I., 2001
    The area of discourse acquisition and writing in higher education has become a much researched field. In South Africa the interest in discourse acquisition and writing has been partly in response to the change in student profile, particularly over the past ten years. While South African researchers ...
  8. Teacher responses to the Namibian education reform : a case study of two Caprivi schools
    Kamwi, K.K., 2002
    Effective implementation of education reforms consists of alterations in curriculum materials, instructional practices and behaviour, beliefs and understandings on the part of the teachers involved in the reform (Fullan and Hargreaves, 1993: 5). A process of implementation is therefore, a learning p ...
  9. Extending the reach of personal area networks by transporting Bluetooth communications over IP networks
    Mackie, D.S., 2007
    This thesis presents an investigation of how to extend the reach of a Bluetooth personal area network by introducing the concept of Bluetooth Hotspots. Currently two Bluetooth devices cannot communicate with each other unless they are within radio range, since Bluetooth is designed as a cable-replac ...
  10. Studies towards the development of novel multidentate ligands
    Magqi, N., 2007
    In this study, attention has been given to the design and synthesis of novel multidentate ligands for use in the construction of ruthenium-based metathesis catalysts, and their chelating potential has been explored by computer modelling at the Density Functional Theory (DFT) level. Both Kemp’s triac ...
