  1. Ambient air quality impacts of a coal-fired power station in Lephalale area
    Muthige, Mavhungu Sydney, 2014-03-04T11:46:37Z
    Lephalale Municipality is a predominantly rural Municipality with 38 villages, two townships (Marapong and Onverwacht) and one town, Lephalale. Lephalale, formerly known as Ellisras, is a town situated in the “heart of the Bushveld” in Limpopo province. The town is growing rapidly and more industrie ...
  2. Botanical analysis of selected historically-occupied cave sites in the Limpopo province, South Africa
    Hardwick, Shannon Kelly, 2014-03-04T12:38:35Z
    This study set out to identify and interpret botanical remains from Historic Cave, Balerno Main Shelter and Balerno Shelter 2 in the Limpopo Province. Botanical remains were identified through comparative collections, and quantified through a raw count and presence analysis. They were interpreted th ...
  3. Do multi-scaled patterns in a semi-arid savanna show evidence of complex systems derived structure?
    Barichievy, Christopher, 2014-03-04T12:49:24Z
    The detection of hierarchically nested structure in a semi-arid savanna as predicted by complex systems theory requires a method that detects context specific multi-scaled pattern in a proxy that represents the net effect of system processes. Statistical assumptions preclude the use of many traditio ...
  4. Development and evaluation of efficient diagnostic tools for Cassava mosaic and Cassava brown streak diseases
    Rajabu, Cyprian Aloyce, 2014-03-05T07:36:00Z
    Cassava (Manihot esculenta Crantz) is affected by two major viral diseases, namely Cassava brown streak disease (CBSD) and Cassava mosaic disease (CMD). Accurate and efficient detection and identification of plant viruses are fundamental aspects of virus diagnosis leading to sustainable disease mana ...
  5. Classical lie point symmetry analysis of models arising in contaminant transport theory
    Mkhonta, Zwelithini Fanelo, 2014-03-05T07:49:47Z
    Groundwater contamination and soil salinisation are a major environmental problem worldwide. Living organisms depend largely on groundwater for their survival and its pollution is of course of major concern. It therefore goes without saying that remedial processes and understanding of the mathema ...
  6. Geophysical studies of the crust and uppermost mantle of South Africa.
    Kgaswane, Eldridge Maungwe, 2014-03-05T07:56:51Z
    The general aim of this thesis is to investigate heterogeneity in the structure of the crust and uppermost mantle of Archaean and Proterozoic terrains in southern Africa and to use the findings to advance our understanding of Precambrian crustal genesis. Teleseismic, regional and local seismic re ...
  7. The impact of long-term partial sleep deprivation in unipara mothers
    Strous, Terri Tanya, 2014-03-05T08:39:45Z
    Most sleep deprivation studies show increased body mass, increased hypertension, increased Type 2 Diabetes, obesity, cardiovascular issues and even death. There is a paucity of research in sleeping patterns of first time Caucasian mothers of babies between six and twelve months old in South Africa. ...
  8. Novel syntheses of 5- and 7- azaindole derivatives
    Leboho, Tlabo Caiphus, 2014-03-05T08:46:27Z
    This thesis describes the application of the Sonogashira coupling reaction to access a variety of 5-and 7-azaindoles derivatives. The background chapter paints a picture about the importance of indole-containing compounds and azaindole-containing compounds. In this first chapter, discovery, synth ...
  9. A theoretical investigation of structural, electronic and optical properties of some group 10, 11 and 12 transition-metal nitrides
    Suleiman, Mohammed Suleiman Hussein, 2014-03-05T08:53:25Z
    Nitrides of late transition metals possess interesting properties leading to different technological applications, yet, due to many factors, synthesis and reliable characterization of the physical properties of these materials constitute a big challenge. In this work, we present a detailed firstprin ...
