The democratic elections in 1994 marked the formal end of apartheid. During apartheid
'race' was, for the most part, a somewhat rigid construct which, despite many nuances and
complexities, typically seemed to frame ...
This qualitative research project investigated the ideas of a small group of learners in the first
year physics course at the University of the Witwatersrand in the area of atmospheric (air)
pressure. These ideas constitute ...
Based on the perceived need for improved graphing skills of students at first-year university level, two
lecturers wanted to produce a web-based computer programme to improve first-year university biology
students’ ability ...
This study investigated how first-year university students at Universidade Pedagógica (Pedagogical University) in Maputo-Mozambique brought their knowledge and thinking of algebra in understanding and working with geometry. ...
This paper focuses on digitization in the African continent. It highlights the fact that some countries in Africa have both the “first” and “third” world characteristics in terms of development and access to information ...
This study carried out an analysis of the Malawi fiscal policy pro poor spending
between 2004 and 2008 in relation to poverty reduction. The focus of the
research was to investigate how much the three social pillars that ...
The effect of the addition of ethanol (2% and 6%) during the Fischer-Tröpsch (FT)
synthesis has been investigated using a 10%Co/TiO2 catalyst in a stirred basket
reactor (T = 220°C, P = 8 bar, H2/CO = 2). The transformation ...
Recently, engineers have devoted a great deal of research to developing a Fischer–Tropsch synthesis (FTS) process with high carbon utilization efficiency and low CO2 emissions. This is desirable not only to improve the ...
A series of experiments in different types of reactors were performed with TiO2 supported cobalt catalyst to gain a better understanding of the phenomena related to Fischer-Tropsch Synthesis (FTS) reaction. The performance ...
This study primarily seeks to confirm two systems of classifying the sulci of the frontal
operculum1 (F3): the radiologically derived system of Ebeling et al (1989) involving four
Types of Sulcal Connections, and the ...
The increasing emergence of drug-resistant pathogens poses a major threat to public health. Although influenced by multiple factors, resistance is often associated with mutations in drug target-encoding or associated genes. ...
Broadband is an important technology for development. Research has proven that development is directly linked to high speed internet. Over the past few years mobile broadband has overtaken fixed-line broadband as a primary ...
The purpose of this research was to examine the perceptions of a selected group of
retrenched participants from Ford Motors in Gauteng in the Dipaakanyo Social Plan
Programme.
An evaluative qualitative study utilizing ...
The U-curves of five different test objects, three of which contain a rod floating object
at different positions within the gap, are characterised. During the testing, a high
speed camera was used to photograph the ...
Esophageal cancer ranks as the second most common cancer among black males in South Africa and patients often seek medical attention when the cancer has already reached advanced stages. Thus, there is a lot of work ...
Wastewater is generated in the production of water-based paints when vessels and filling lines are washed in between batches. This results in a dilute paint wastewater stream. This dissertation concerns the study of the ...
Abstract
This dissertation describes a study of the treatment of wastewater using the
flocculation process. Wastewater samples from Barloworld Plascon paints were
used for the research.
Environmental pressure has ...
The flow characteristics of an on-line analyser were measured using a
stimulus – response technique. The analyser was developed for
monitoring homogeneous catalyst concentrations in a non-aqueous
solution and it was ...
Many environmental and engineering projects require prediction of the velocity of
flow in river channels, in terms of those channel properties and flow characteristics
which induce resisting forces or an energy loss to ...
