Investigating the pathway and fate of inorganic impurities in a bisulfite dissolving pulp production process.
(2011)This study sought to investigate the pathway and fate of metals and Si in a bisulfite pulp production process, at the same time providing a means to mitigate on the residual metals bound in the final pulp. The metals ... -
Investigating the standard method used by Umgeni Darvill Waste Water Works for the determination of pseudo total metal concentrations in their sewage sludge.
(2016)Abstract available in PDF file. -
An investigation in the use of satellite data to develop a geomagnetic secular variation model over Southern Africa.
(2011)Time variations of the geomagnetic field can be classified into two main categories of internal and external origin with respect to the surface of the Earth. It has been found that the variations that take place on longer ... -
An investigation into air stable analogues of Wilkinson's catalyst.
(2010)Since the discovery of Wilkinson’s catalyst and its usefulness in the homogeneous hydrogenation of olefins many investigations have been carried out on trivalent, tertiary phosphine–rhodium complexes.¹ Studies have shown ... -
An investigation into the antimalarial activity of metal chelators
(2008)Malaria remains one of the greatest problems facing developing nations, especially in sub-Saharan Africa. Part of the problem stems from increased resistance to current treatments hence there is a large drive to develop ... -
An investigation into the influence of substituents and extended π-conjugation on the substitution reactions of bifunctional platinum (II) complexes.
(2015)Abstract available in PDF file. -
An investigation into the radioprotective potential of Costus afer and Drymaria cordata extracts on whole-body irradiated mice.
(2021)The need for effective and non-toxic radioprotectors has shifted researchers' attention to plants and natural products as an alternative to synthetic compounds. This study investigated the radioprotective potential of ... -
An investigation of a heterogeneous aminohydroxylation catalyst.
(2010)Os-Zn-Al hydrotalcite-like compounds (HTlc’s) were synthesised by the co-precipitation method and characterised using different techniques (powder XRD, ICP-OES, FT-IR spectroscopy, BET-surface area measurements, SEM and ... -
An investigation of acetone-photosensitised DNA kinetics.
(1992)Ultraviolet (UV) radiation is a potent DNA-damaging agent and a known inducer of mutations and skin cancer. The increasing incidence of skin cancer has emphasised the importance of understanding the mechanistic ... -
Investigation of conceptual and language difficulties affecting the understanding of several mechanics concepts among some African teachers and students.
(1998)The results of national examination in matric and universities showed that African students were performing very poorly in their studies and examinations in science and in physics in particular. The objective in this ... -
An investigation of electric-field-gradient-induced Birefringence in fluids.
(2014)The theory of electric-field-gradient-induced birefringence (EFGIB, the Buckingham effect) is briefly reviewed, and modifications to the Buckingham-effect apparatus are described. These modifications have increased the ... -
An investigation of gas lasers.
(1999)Pulsed lasers have a wide range of applications in industry, medicine and for scientific research. Many of these devices are expensive and have delicate optics. The nitrogen laser is robust and inexpensive to build and ... -
An investigation of high velocity flows in HF radar data during northward interplanetary magnetic field, non-substorm intervals.
(2010)Several previous studies, including one using early Sanae radar data, have found examples of high speed ionospheric plasma flows on the nightside, mapping to the magnetospheric tail, during periods which were magnetically ... -
Investigation of IBMQ quantum device hardware calibration with Markovian master equation.
(2022)In the design of quantum technology, it is crucial to account for the quantum system interacting with its environment to understand the influence of thermal processes and design the devices to avoid e↵ects of relaxation ... -
An investigation of new heterogeneous hydrotalcite-like catalysts for the cis-dihydroxylation of olefins.
(2004)The use of supported catalysts to essentially combine the positive traits offered by both homogeneous and heterogeneous catalysis has become a competitive field of research. In particular, hydrotalcite-like catalysts (HTIc) ... -
An investigation of the complexes of zinc and germanium with 8-hydroxyquinoline.
(1991)The experimental work described in this thesis is aimed at the elucidation of the speciation of the zinc and germanium 8-hydroxyquinoline systems. A knowledge of this speciation could aid in modelling the kinetics of ... -
An investigation of the efficiency of the receiver of a solar thermal cooker with thermal energy storage.
(2013)A small scale solar concentrator cooker with a thermal energy storage system was designed, constructed and tested on the roof of the Physics building at UKZN, Westville campus (GPS co-ordinates: -29.817897, 30.942771) ...
