Evaluating the potential of remote sensing imagery in mapping ground-level fine particulate matter (PM2.5) for the Vaal Triangle Priority Area
(NACA, 2020)The quality of air breathed in South Africa is of great concern, especially in industrialised regions where PM2.5 concentrations are high. Long term exposure to PM2.5 is associated with serious adverse health impacts. ... -
Evaluating the United Kingdom's employee shareholder status provisions in context of the South African position
(LexisNexis Butterworths, 2015)The purpose of this article is to evaluate the introduction of the notion of the employee shareholder in the United Kingdom in the context of the labour and corporate law framework in South Africa. It provides the backdrop ... -
Evaluating three commonly used growth media for assessing fumonisin analogues FB1, FB2 and FB3 production by nine Fusarium verticillioides isolates
(Taylor & Francis, 2017)Maize is most often infected by the fumonisin-producing Fusarium verticillioides. Total fumonisins of natural infected grain is made up of FB1, FB2 and FB3 with FB1 occurring naturally at higher levels. A maize plant can ... -
Evaluation and optimization of synthetic routes from dihydroartemisinin to the alkylamino-artemisinins artemiside and artemisone: a test of N-glycosylation methodologies on a lipophilic peroxide
(Elsevier, 2018)10-Alkylamino-artemisinins including artemiside and artemisone display enhanced activities against malaria. Earlier, dihydroartemisinin (DHA) TMS ether was converted by trimethylsilyl bromide into the 10-β-bromide that ... -
Evaluation and prediction of slow pyrolysis products derived from coals of different rank
(Elsevier, 2017)When coal is heated slowly (<10 °C/min), as in the Lurgi Fixed Bed Dry Bottom (FBDB) gasification process, products formed in the pyrolysis region of the gasifier include gas liquor, condensable tar, oil and non-condensable ... -
The evaluation and quantification of respirable coal and silica dust concentrations: a task-based approach
(Taylor & Francis, 2014)Silicosis and coal worker's pneumoconiosis are serious occupational respiratory diseases associated with the coal mining industry and the inhalation of respirable dusts containing crystalline silica. The purpose of this ... -
The evaluation of 1,4-benzoquinones as inhibitors of human monoamine oxidase
(Elsevier, 2017)The monoamine oxidase (MAO) enzymes are of considerable pharmacological interest and inhibitors are used in the clinic for the treatment of major depressive disorder and Parkinson's disease. A limited number of studies ... -
The evaluation of 1-tetralone and 4-chromanone derivatives as inhibitors of monoamine oxidase
(Springer, 2020)Monoamine oxidase (MAO) is of much clinical relevance, and inhibitors of this enzyme are used in the treatment for neuropsychiatric and neurodegenerative disorders such as depression and Parkinson’s disease. The present ... -
Evaluation of 2-benzylidene-1-tetralone derivatives as antagonists of A1 and A2A adenosine receptors
(Wiley, 2018)Antagonists of the adenosine receptors (A1 and A2A) are thought to be beneficial in neurological disorders, such as Alzheimer's and Parkinson's disease. The aim of this study was to explore 2-benzylidene-1-tetralone ... -
Evaluation of a detailed radiation heat tranfer model in a high temperature reactor systems simulation model
(Elsevier, 2008)Radiation heat transfer is a major mode of heat transfer in high temperature gas-cooled reactors (HTRs) because of the high operating temperatures. It is, however, a difficult phenomenon to calculate in full detail due to ... -
Evaluation of a domestic-use low-smoke fuel produced via the pyrolysis of lump coals

Evaluation of a facial recognition engines for a surveillance system
(IEEE, 2019)This paper presents the evaluation of a facial recognition system when considered in an operational context for the South African environment. Often, performance measures, such as recognition rate, are considered outside ... -
Evaluation of a flexible NOTA-RGD kit solution using Gallium-68 from different 68Ge/ 68Ga-generators: pharmacokinetics and biodistribution in nonhuman primates and demonstration of solitary pulmonary nodule imaging in humans
(Springer, 2016)Purpose: Radiopharmaceuticals containing the motive tripeptide arginyl-glycyl-asparatic acid (RGD) are known to target ανβ3 integrins during tumor angiogenesis. A more generic kit radiolabeling procedure accommodating ... -
The evaluation of a frame-of-reference training programme for intern psychometrists
(AOSIS, 2013)Orientation: The use of assessment centres (ACs) has drastically increased over the past decade. However, ACs are constantly confronted with the lack of construct validity. One aspect of ACs that could improve the construct ... -
Evaluation of a Health Setting-Based Stigma Intervention in Five African Countries
