Fabrication and kinetic modeling of cytochrome P4502D6 amperometric biosensors for serotonin reuptake inhibitors
(University of the Western Cape, 2005)
An amperometric biosensor was prepared by in situ deposition of cytochrome P4502D6 (CYP2D6, P4502D6) enzyme on a polyaniline (PANI)-doped glassy carbon electrode. The PANI film was electrochemically deposited on the electrode ...
The application of high capacity ion exchange absorbent material, synthesized from fly ash and acid mine drainage, for the removal of heavy and trace metals from secondary co-disposed process waters
(University of the Western Cape, 2005)
The objective of this study was to investigate the feasibility of the application of low cost high capacity inorganic ion exchange material, synthesized form collected fly ash and acid mine drainage solid residues, for the ...
Polymer/nano-organic composite proton exchange membranes for direct methanol fuel cell application
(University of the Western Cape, 2005)
The proton exchange membrane is one key component of direct methanol fuel cells, which has double functions of conducting protons, separating fuels and oxidant. At present, the performance and price of sulfonic acid proton ...
Optimizing the ion source for polarized protons
(University of the Western Cape, 2005)
Beams of polarized protons play an important part in the study of the spin dependence of the nuclear force by measuring the analyzing power in nuclear reactions. The source at iThemba LABS produces a beam of polarized ...
Microbiology of fly ash-acid mine drainage co-disposal processes
(University of the Western Cape, 2005)
The waste products acid mine drainage formed during coal mining and fly ash from coal burning power generation, pose substantial environmental and economic problems for South Africa. Eskom has developed a remediation system ...
Towards a classification system of significant water resources with a case study of the Thukela river
(University of the Western Cape, 2005)
The increasing demand for water to provide for South Africa's growing population has resulted in increasing pressure being placed on the country's limited water resources. Water developments however cannot be undertaken ...
Apoptotic markers in ejaculated human spermatozoa
(University of the Western Cape, 2005)
The role of male germ cell death in spermatogenesis is an important one as it removes dysfunctional or genetically damaged germ cells and is necessary to maintain an optimal germ cell to Sertoli cell ratio. The formation ...
Investigating an integrated teaching methodology as a means to prepare students for university studies in mathematics
(University of the Western Cape, 2005)
A key issue for the success of students entering a first year mathematics course at tertiary level is whether or not they have an integrated understanding and view of the mathematical concepts acquired at school. Various ...
Determination of the photopeak detection efficiency of a HPGe detector, for volume sources, via Monte Carlo simulations
(University of the Western Cape, 2005)
The Environmental Radioactivity Laboratory (ERL) at iThemba LABS undertakes experimental work using a high purity germanium (HPGe) detector for laboratory measurements. In this study the Monte Carlo transport code, MCNPX, ...
Skills, training and support for carers in HIV/AIDS community home-based care: a case study of carers in Chikankata, Zambia
(University of the Western Cape, 2005)
The high prevalence of HIV/AIDS in Zambia has led to the development of innovative ways of coping with sickness related to this infection. HIV/AIDS home-based care is one such innovation designed in Chikankata Hospital in ...
