  1. Multi-scale tilt depth estimation
    Van Buren, Reece, 2014-03-04T11:17:18Z
    Many an approach to the estimation of magnetic source depths from magnetic data has been investigated over the past half a century. These approaches have been shown to have particular strengths and weaknesses with few implemented on a wide scale, commercial basis. A review of many of the more po ...
  2. The adaptor protein 1 medium subunit of plasmodium falciparum
    Bezuidenhout, Belinda Catherine, 2014-03-04T11:22:59Z
    Malaria is a tropical disease affecting millions of people worldwide. Plasmodium falciparum is the causative agent of the most severe form of malaria, and therefore insights into the molecular mechanisms by which it functions are critical. The intraerythrocytic stage of the life cycle is responsible ...
  3. Potential flows and transformation groups
    Pereira, Kevin Paul, 2014-03-04T11:27:39Z
    In this work we will consider the steady and two-dimensional potential flow of an incompressible fluid past a body without friction. Contrary to common experience, we will show that it is possible to calculate the Lie point symmetries that will leave the boundary value problem invariant. We are a ...
  4. Middle Permian continental biodiversity changes as reflected in the Beaufort Group of South Africa: a bio-and lithostratigraphic review of the Eodicynodon, Tapinocephalus and Pristerognathus assemblage zones
    Day, Michael Oliver, 2014-03-04T11:38:14Z
    The fluvio-lacustrine rocks of the Beaufort Group, South Africa have long been known for their tetrapod fossil record, which is the richest and most complete Middle Permian to Middle Triassic record for any terrestrial sequence in the world. The abundance of fossil material has enabled the Beaufo ...
  5. 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 ...
  6. 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 ...
  7. 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 ...
  8. 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 ...
  9. 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 ...
  10. 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 ...
