Experimental densities, speeds of sound, and refractive indices of the binary mixtures {1-butyl-3-methylimidazolium methylsulphate ([BMIM]+[MeSO4]−) + methanol, or 1-propanol, or 2-propanol, or 1-butanol} were measured ...
Dental composite materials: highlighting the problem of wear for posterior restorations

Le Roux, Andre Rayne; Lachman, Nirusha (South African Dental Association, 2007)

Manufacturers of dental composites promote their products as having ideal wear resistant characteristics. Evaluation of the problems that persist with wear of dental composites is made. Recommendations for further research ...
Design and evaluation of alumina/feldspar resin infiltrated dental composite materials

Le Roux, Andre Rayne (2008)

Introduction: Incorporating a feldspar chemical bond between alumina filler particles is expected to increase the wear resistant and flexural strength properties, while reducing flexibility of dental composites. Aims and ...
Design and implementation of an intelligent vision and sorting system

Li, Zhi (2009)

This research focuses on the design and implementation of an intelligent machine vision and sorting system that can be used to sort objects in an industrial environment. Machine vision systems used for sorting are either ...
Design and operation of a laboratory scale photobioreactor for the cultivation of microalgae

Bhola, Virthie (2011)

Due to greenhouse gas emissions from fossil fuel usage, the impending threat of global climate change has increased. The need for an alternative energy feedstock that is not in direct competition to food production has ...
A design methodology for the supply of subterranean water through the use of wind energy

Marais, Brett Richard (2005)

The Reconstruction and Development Programme adopted by the Government of National Unity is more than a list of the services required to improve the quality of life of the majority of South Africans. It is not just a call ...
Detection methods of organic acid in steam/water circuits and optimisation using HPLC-UV

Ramrung, Arthi (2009)

This study was mainly a response to a challenge faced by ESKOM in its coal-fired power stations. In spite of using high purity water to drive the turbines, the latter were damaged by ‘pitting’, possibly related to acids ...

Khan, Imtiaz (2004)

The purpose of this study was to determine the core competencies of Sappi Forest Product division as a basis for establishing future developments. The literature focused on the resource-based view where the analysis ...
A determination of normal reference ranges for bone mineral density for Indian women of varying age groups in KZN : the impact of local data on the diagnosis of osteoporosis

Sunder, Roshnee (2006)

The aim of this research was to determine normal bone mineral density (BMD) reference ranges (means and standard deviations) for the lumbar spine, total hip and distal forearm, for Indian women of varying age groups in ...
Determination of the antimicrobial properties of Withania somnifera and Xysmalobium undulatum plant tinctures in terms of the disc diffusion assay and the agar dilution sensitivity test

Motara, Farhad Essop (2007)

This study was designed to investigate the antimicrobial efficacy of Withania somnifera and Xysmalobium undulatum plant tinctures in 62% ethanol in inhibiting the in vitro growth of Escherichia coli, Pseudomonas aeruginosa ...
Determination of the heterotrophic and autotrophic active biomass during activated sludge respirometric batch assays using molecular techniques

Ismail, Arshad (2008)

Activated sludge models now in use worldwide for the design and operation of treatment systems use hypothetical concentrations of active organisms. In order to validate and calibrate model outputs, concentrations and ...
Development and evaluation of silicone membrane as aerators for membrane bioreactors

Mbulawa, Xolani Proffessor (2005)

In bubble-less aeration oxygen diffuses through the membrane in a molecular form and dissolves in the liquid. Oxygen is fed through the lumen side of silicone rubber tube. On the outer surface of the membrane there is a ...
The development of a framework to retain migrating South African undergraduate Advanced Life Support paramedics

Govender, Pregalathan (2010)

South Africa currently has 1631 registered Advanced Life Support (ALS) paramedics to tend to the pre-hospital advanced life support needs of just under 50 million people. Compared to the globally accepted ratio of 1:10 ...
Development of a hybrid fuzzy-mathematical cleaner production evaluation tool for surface finishing
