Investigating soil algae and cyanoprokaryotes on gold tailings material in South Africa
(2014)
Gold mine tailings material facilities are characterized by sparse vegetation and an
abundance of dust. Mine tailings facilities are examples of extreme geotechnical and
geochemical conditions which make it almost ...
A comparative study between Pt and Rh for the electro-oxidation of aqueous SO₂ and other model electrochemical reactions
(2014)
The ever increasing demand for a clean and renewable energy source has stimulated research for alternatives for the use of fossil fuels, which contribute significantly to global warming. The SO2 oxidation reaction was ...
Group actions and ergodic theory on Banach function spaces
(2014)
This thesis is an account of our study of two branches of dynamical systems
theory, namely the mean and pointwise ergodic theory.
In our work on mean ergodic theorems, we investigate the spectral theory of
integrable ...
A new perspective on the importance of glycine N–acyltransferase in the detoxification of benzoic acid
(2014)
Despite being the first biochemical reaction to be discovered, the glycine conjugation pathway remains poorly
characterised. It has generally been assumed that glycine conjugation serves to increase the water solubility ...
Mathematics teachers' metacognitive skills and mathematical language in the teaching-learning of trigonometric functions in township schools
(North-West University, 2014)
Metacognition is commonly understood in the context of the learners and not their teachers. Extant literature focusing on how Mathematics teachers apply their metacognitive skills in the classroom, clearly distinguishes ...
Planning for sustainable communities : place-making through layout and design approaches
(North-West University, 2014)
The survival and quality of life of people are irrefutably dependent on the natural environment in which they live. In order to ensure that the basic needs of man are consistently satisfactorily met in the long-term, the ...
A model for enhancing volitional strategies' use and mathematics achievement in grade 9 in a rural community school
(North-West University, 2014)
The contextual factors that affect effective Mathematics learner engagement patterns are due to lack of self-regulated learning and enthusiastic volitional use. An active role for Mathematics learners incorporates use of ...
Planning child-friendly spaces for rural areas in South Africa : the Vaalharts case study
(North-West University, 2014)
Child-friendly spaces are not successfully implemented in South Africa due to problems such as urbanization, development pressure, lack of qualitative open spaces and lack of policy and legislation guiding the planning and ...
Characterisation of proton exchange membranes in an H₂SO₄ environment
(North-West University, 2014)
In light of the world‟s growing demand for energy that is environmentally friendly and sustainable, energy sources such as hydrogen have been considered potential contenders. Hydrogen, which can be used for energy storage, ...
Frogs about town : aspects of the ecology and conservation of frogs in urban habitats of South Africa
(North-West University, 2014)
Globally urbanisation impacts on 88% of amphibian species and is recognised as a major cause for the observed amphibian declines. This is as result of habitat fragmentation, alteration in habitat morphology and degradation ...
