1-D particle-in-cell simulations of plasmas with kappa velocity distributions.
(2013)The main aim of this project was the development of a particle-in-cell (PIC) plasma simulation code. While particle-in-cell simulations are not new, they have largely focused on using an initial Maxwellian particle ... -
2,4,6-Trichloro-1,3,5-triazine as a triorthogonal chemoselective linker.
(2019)Abstract available in PDF. -
2-generations of the sporadic simple groups.
(1997)A group G is said to be 2-generated if G = (x, y), for some non-trivial elements x, y E G. In this thesis we investigate three special types of 2-generations of the sporadic simple groups. A group G is a (l, rn, n )-generated ... -
3D modelling segmentation, quantification and visualisation of cardiovascular magnetic resonance images.
(2014)Progress in technology in the field of magnetic resonance imaging (MRI) has provided medical experts with a tool to visualise the heart during the cardiac cycle. The heart contains four chambers namely the left and right ... -
A 40,000-year record of vegetation and fire history from the Tate Vondo region, Northeastern Southpansberg, South Africa.
(2014)Records from the Quaternary period are used to confirm possible inferred climatic changes, reveal the responses of species to these changes, and serve as an archive against which modern environmental dynamics can be ... -
57 Fe Mössbauer studies of 57 Mn* implanted III-V semiconductors InP and InAs.
(2011)III-V compound semiconductors such as Gallium Arsenide, Indium Phosphide as well as Indium Arsenide have recently demonstrated the capability of applications in high speed semiconductor devices compared to those made from ... -
A critical analysis of current approaches to SMME development and support within the eThekwini Municipal Area.
(2009)Small, Medium and Micro Enterprises (SMMEs) are considered to be the engines of growth of any economy. In the light of recent economic events and the recession that is surging rapidly across the globe, more and more attention ... -
A critical assessment of the Namibian protected area management effectiveness tracking tool.
(2010)Protected Areas (PAs) are one of the most effective mechanisms for biodiversity conservation. They are found in almost every country and have been adopted by the international community through various conventions and ... -
A framework to improve irrigation design and operating strategies in the South African sugarcane industry.
(2009)The purpose of this study was to develop a framework to assess irrigation design and operating strategies. This objective was achieved successfully and the framework was applied to formulate guidelines to increase farm ... -
A laboratory and glasshouse investigation on the effect of liming with fly ash and processed stainless steel slag on two contrasting South African soils.
(2008)Soil acidity is a major land degradation problem that limits crop production globally. The high cost of traditional liming materials (calcitic limestone, dolomite etc.) and the vast areas of land that require liming have ... -
A review of the fluvial geomorphology monitoring of the receiving streams of the Mooi-Mgeni [River] Transfer Scheme Phase 1.
(2009)The Mgeni River is the major water resource for the eThekwini Metropolitan and Msunduzi Municipalities. At the end of 2002, the Mooi-Mgeni Transfer Scheme Phase 1, which transfers water from the Mooi River into the Mgeni ... -
A semi-empirical formulation for determination of rain attenuation on terrestrial radio links.
(2010)Advances in today’s fast growing communication systems have resulted in congestion in the lower frequency bands and the need for higher capacity broadband services. This has made it inevitable for service providers to ... -
A simulation study of cane transport system improvements in the Sezela Mill area.
(2009)The South African sugar industry is of significant local and international importance and covers an area in excess of 450 000 hectares. This area yields approximately 21 million tons of sugarcane per annum which is transported ... -
A study of bruchid resistance and its inheritance in Malawian dry bean germplasm.
(2007)Dry bean (Phaseolus vulgaris L.) is economically and nutritionally an important legume, not only in Malawi, but in many parts of Africa and Latin America. Unfortunately, two bruchid species (Acanthoscelides obtectus Say, ... -
A study of rain attenuation on terrestrial paths at millimetric wavelengths in South Africa.
(2006)Rain affects the design of any communication system that relies on the propagation of electromagnetic waves. Above a certain threshold of frequency, the attenuation due to rain becomes one of the most important limits to ... -
A systems-thinking based evaluation of predator conflict management on selected South African farms.
(2008)The backbone of this study was a systems thinking based analysis of the management and control of predators as practiced in South Africa since the advent of Europeans in 1652. The first bounties were introduced for a variety ... -
An ab initio molecular orbital study of some binary complexes of water.
(1996)Ab initio molecular orbital theory has been successful in predicting the stabilities of many weak complexes; typical of these are the complexes formed between water and various small molecules. To account for the correlation ... -
Abandoning the Ark in Durban: development, displacement, resettlement and livelihood struggles.
(2021)Forced removals, the theme of this thesis, through evictions, clean-up campaigns and development-induced displacement, results in the ‘hygienisation’ of public space and the ‘violent un-homing’ of vulnerable communities. ... -
Above- and belowground competition in Savanna systems.
(2008)The structure and composition of savanna vegetation is influenced by resource availability and disturbance. Grasses, a major component of savannas, influence this resource availability by competing directly with trees ...
