Combustion stress in compression-ignition engines.
South Africa produces alternative fuels from a number of different sources. The properties of a fuel are known to affect the nature of combustion in compression-ignition engines significantly, and have occasionally ...
Crop water requirements for irrigation planning in South Africa.
Irrigation in 1980 accounted for approximately 52 per cent of the water consumed in Southern Africa. The need for planning water resources in the agricultural sector is therefore apparent. Much of Southern Africa's ...
A diagnostic quasi-dimensional model of heat transfer and combustion in compression-ignition engines.
Investigations into the combustion of alternative fuels in compression-ignition engines in South Africa have underlined the inadequacies of existing zero-dimensional combustion models. The major aspect of concern in ...
The development and evaluation of a performance-based standards approach for regulating the use of heavy vehicles in South Africa.
The regulation of the use of vehicles on the road network is aimed at ensuring acceptable safety and recovery of road maintenance costs, as well as minimising congestion, road wear, excessive noise and air pollution. The ...
The hydrological effects of fire in South African catchments.
Stream-flow and storm-flow in four small catchments were analysed by the paired catchment method for a response to fire. Two of the catchments were vegetated with over-mature fynbos (the indigenous scrub vegetation of ...
A comprehensive qualitative and quantitative assessment of harvesting and other sugarcane supply chain disruptions within the Eston Mill supply area.
The Eston Mill, which was established in 1994, is the newest in the KwaZulu-Natal sugar belt. Like for most other mills, it can be argued that there are inefficiencies in the supply chain due to systemic issues, which ...
The preparation and novel application of diphosphorus xanthene family ligands in homogeneous catalysis.
Abstract available in print version.
An assessment of the feasibility of quality indicators for the postharvest deterioration of sugarcane (Saccharum officinarum L.)
Sugarcane deterioration remains one of the most important supply chain efficiency leverage points in the South African sugar industry. Cane quality has been identified as an issue that has the potential to improve the ...
Development and optimization of an integrated post-harvest management system for the handling and storage of fresh tomatoes in South African chains.

Technological viability of coffee husk ash, soil rich in koalinite-ferrinatrite and koalinite-geothite for the adsorptive removal of chromium (VI) from industrial wastewater.
Most industries in developing countries discharge a high amount of untreated wastewater, containing toxic chemicals, into nearby water bodies. Heavy metals and chemicals above permissible levels can be emitted to the ...
