Calibration techniques for 21-cm experiments with application to HERA: quasi-redundant calibration analysis.
(2018)Upcoming 21 cm observations promise to open a new window in our understanding of the universe from the epoch of recombination down to redshift of z 1. However, measurements of 21 cm signals come at a high cost since ... -
Capillary electrophoresis and related techniques for the analysis of fresh water algal toxins.
(1997)As cyanobacteria (also known as blue green algae) produce a range of cyclic peptides which are highly toxic, capillary electrophoresis and associated techniques have been investigated to assess their applicability ... -
The Carbamate group: migrational and leaving properties: towards the synthesis of flavenes.
(1996)Abstract available in PDF. -
The catalysed activation of n-octane over iron modified hydroxyapatites.
(2014)This research effort investigated the activation of n-octane by oxidative dehydrogenation and dehydrogenation over iron substituted and iron supported on hydroxyapatite catalysts. Pure hydroxyapatite and iron substituted ... -
Characterisation and quantification of wood extractives and their impact on pitch.
(2011)The aims of this study were to characterise and quantify wood extractives in E. grandis and E. nitens and determine the impact of wood extractives on pitch formation. Initially a comparison was made with individual solvent ... -
Characterisation and quantum application of plasmonic waveguides.
(2016)Plasmonics o ers sub-di raction confinement of light, which a ords enhanced coupling to emitter systems (e.g. quantum dots). This feature makes possible a range of on-chip quantum photonic components - most notably ... -
Characterisation of extracellular polysaccharides produced from a fungal pathogen of sugarcane.
(2016)Abstract available in PDF file. -
Characterisation of polarisation-entangled photon source for quantum key distribution.
(2016)Entanglement in real physical systems has been of great interest due to its importance in quantum mechanics. It has applications related to quantum information science speci cally quantum cryptography since it eliminates ... -
Characterisation of SAPPI SAICCOR pulp mill's effluent.
(2001)SAPPI SAJCCOR, whose factory is situated south of Durban, South Africa, is one of the few paper and pulp mills that uses the acid sulphite process with calcium and magnesium bases to produce a high-grade cellulose pulp. ... -
Characterization and improvement of a direct solar radiation detector.
(2004)A low-cost Direct Solar Radiation Detector (DSRD) was developed in house in the Department of Physics at the University of KwaZulu-Natal (Westville). A main use of this instrument is to gather solar energy data that are ... -

A chemical and pharmacological investigation of three South African plants.
(2006)Three plant species (Phylica paniculata Willd., Pergularia daemia Forssk. and Monsonia -
Chemical constituents from Elytropappus rhinocerotis and Rhoicissus tridentata : structural and activity studies.
(2015)Traditional medicines are used by approximately 80% of South African population for their primary health care needs, but the chemistry and biological activity of many medicinal plants have not yet been investigated. This ... -
The chemical constituents of Ehretia rigida, Apodytes dimidiata and Ocotea kenyensis.
(1998)Three species have been investigated in this project: Iso-ocobullenone (p 23) and its probable precursor (p 27) have been isolated from the leaves and bark of Ocotea kenyensis. This is only the second time that these ... -
A chemical investigation of a KwaZulu-Natal medicinal plant, Momordica foetida Schum. & Sond.
(1994)Momordica foetida Schum. & Sond. (Cucurbitaceae), locally known as iNtshungu, is widely used by the Zulu people of Natal-KwaZulu for the treatment of a variety of ailments. The dried leaves leaves and stems of this plant ... -
The chemical investigation of four medicinal plants.
(2000)This thesis describes a phytochemical investigation of four medicinal plants, namely, Agave attenuata (Agavaceae), Balanites maughamii (Balanitaceae), Astrotrichilia parvifolia (Meliaceae) and Combretum fragrans (Combretaceae). ... -
