Brine treatment using natural adsorbents
(University of the Western Cape, 2011)
Studies involving the use of natural clays such as bentonite, montmorillonite and natural zeolite clinoptilolite in water treatment have been reported. Researchers suggested cost effective processes, such as ion-exchange ...
Application of fluid electrical conductivity logging for fractured rock aquifer characterisation at the University of the Western Cape's Franschhoek and Rawsonville research sites
(University of the Western Cape, 2011)
Characterisation of fractured rock aquifers is important when dealing with groundwater protection and management. Fractures are often good conduits for water and contaminants, leading to high flow velocities and the fast ...
Numerical singular perturbation approaches based on spline approximation methods for solving problems in computational finance
(University of the Western Cape, 2011)
Options are a special type of derivative securities because their values are derived from
the value of some underlying security. Most options can be grouped into either of
the two categories: European options which can ...
Codes, graphs and designs related to iterated line graphs of complete graphs
(University of the Western Cape, 2011)
In this thesis, we describe linear codes over prime fields obtained from incidence
designs of iterated line graphs of complete graphs Li(Kn) where
i = 1,2. In the binary case, results are extended to codes from ...
How Do Teachers and Learners Navigate the Terrain of Ecology and What are the Associated Conceptual Understandings?
(University of the Western Cape, 2011)
This thesis relates the teaching of ecology in schools to the requirements of the National Curriculum Statements, Grades R-9 and Grades 10-12, for Natural and Life Sciences. It examines the conceptual understanding of the ...
Stigmatization of and discrimination against people who are HIV positive, or have AIDS - a female perspective in Zwartwater, Eastern Cape Province
(University of the Western Cape, 2011)
The aim of this study is to investigate the perceived stigmatization of and discrimination against people who are HIV positive or people who are living with AIDS. One questionnaire was used to collect qualitative and ...
Impedimetric and electrode kinetic dynamics of DNA aptamer nanobiosensors for estrogeneous endocrine disruptors
(University of the Western Cape, 2011)
In this work, DNA aptamer biosensor systems were developed for the detection of l7p-estradiol - an estrogeneous endocrine disrupting chemical (EDC). Endocrine disrupting chemicals are group of compounds that impact negatively ...
Electro chemiluminescence and organic electronics of derivatised poly(aniline sulphonic acid) light-emitting diodes
(University of the Western Cape, 2011)
Electrochemiluminescence (EeL) is applied for industrial applications that have considerable potential, such as clinical diagnostic, analytical chemistry, and light-emitting devices, due to selectivity, sensitivity for ...
An evaluation of potential management options to Reduce water use in communal gardens on the cape Flats
(UWC, 2011)
The aim of this project was to evaluate various potential management options in their ability to reduce the water use of small and medium scale vegetable gardens on the Cape Flats. The water use of these gardens has a ...
