Developing a neighbourhood sustainability assessment model: an approach to sustainable urban development
(Elsevier, 2019)In every neighbourhood urban development; attention is directed towards overcoming the spatial disparities, rapid urbanisation, socio-economic imbalances and transport system connectivity challenges that influence the urban ... -
Developing a site selection tool to assist reintroduction efforts for the Southern Ground– Hornbill Bucorvus leadbeateri
(Taylor & Francis. Co-published by NISC., 2013)The Southern Ground-Hornbill BucolVus leadbeateri (SGH) is regarded as Vulnerable globally and Endangered in South Africa as a result of losing close to 70% of its range and 50% of its historic population in the country. One ... -
Developing an apicomplexan dna barcoding system to detect blood parasites of small coral reef fishes
(American Society of Parasitologists, 2017)Apicomplexan parasites are obligate parasites of many species of vertebrates. To date, there is very limited understanding of these parasites in the most-diverse group of vertebrates, actinopterygian fishes. While DNA ... -
Developing an impairment loss given default model using weighted logistic regression illustrated on a secured retail bank portfolio
(MDPI, 2019)This paper proposes a new method to model loss given default (LGD) for IFRS 9 purposes. We develop two models for the purposes of this paper—LGD1 and LGD2. The LGD1 model is applied to the non-default (performing) accounts ... -
Developing soft skills (also known as pervasive skills): usefulness of an educational game
(Emerald, 2016)Purpose – The purpose of this paper is to evaluate the usefulness of an educational game to develop soft skills (also known as pervasive skills), from the perspectives of three groups of role-players (student participants, ... -
Development and comparison of payment behaviour prediction models for two South African state departments
(AOSIS, 2017)Background: No credit rating methodology currently exists for any of South Africa’s sub nationals. Aim: To develop a generic, quantitative credit rating methodology for the Department of Health and the Department of ... -
Development and evaluation of a rapid multiplex-PCR based system for Mycobacterium tuberculosis diagnosis using sputum samples
(Elsevier, 2015)Global tuberculosis (TB) control and eradication is hampered by the unavailability of simple, rapid and affordable diagnostic tests deployable at low infrastructure microscopy centers. We have developed and evaluated the ... -
Development and evaluation of real time RT-PCR assays for detection and typing of bluetongue virus
(Public Library of Science, 2016)Bluetongue virus is the type species of the genus Orbivirus, family Reoviridae. Bluetongue viruses (BTV) are transmitted between their vertebrate hosts primarily by biting midges (Culicoides spp.) in which they also ... -
Development and testing of an anion exchange membrane electrolyser
(Elsevier, 2015)In the context of energy policy and the use of renewable energies, our research institute collaborates with other partners on the development of a compact, environmental-friendly and effective electrolyser for efficient ... -
Development and validation of an HIV risk scorecard model
(IEEE, 2013)This research paper covers the development of an HIV risk scorecard using SAS Enterprise MinerTM. The HIV risk scorecard was developed using the 2007 South African annual antenatal HIV and syphilis seroprevalence data. ... -
Development and validation of LC-ESI-MS/MS methods for quantification of 27 free and conjugated estrogen-related metabolites
(Elsevier, 2020)An imbalance in the estrogen metabolism has been associated with an increased risk of breast cancer development. Evaluation of the estrogen biotransformation capacity requires monitoring of various estrogen metabolites. ... -
Development and worldwide use of non-lethal, and minimal population-level impact, protocols for the isolation of amphibian chytrid fungi
(Nature, 2018)Parasitic chytrid fungi have emerged as a significant threat to amphibian species worldwide, necessitating the development of techniques to isolate these pathogens into culture for research purposes. However, early ... -
Development in astronomy and space science in Africa
(Nature, 2018)The development of astronomy and space science in Africa has grown significantly over the past few years. These advancements make the United Nations Sustainable Development Goals more achievable, and open up the possibility ... -
The development of a Cu(I)/pyrazolylpyridineamine catalyst system for the hydroxylation of aryl halides
(Elsevier, 2020)A catalyst system comprising of pyrazolylpyridineamine/Cu(I)/CsOH is reported. for the hydroxylation of aryl iodides and bromides with moderate to outstanding yields, without the use of an inert atmosphere. A comprehensive ... -
Development of a low purity aluminum alloy (Al6082) anodization process and its application as a platinum-based catalyst in catalytic hydrogen combustion
(Elsevier, 2020)In this study, we present a process to prepare a Pt/anodized aluminum oxide (AAO) catalyst for catalytic hydrogen combustion applications using low cost and low aluminum (Al) purity Al6082 alloy (97.5% Al) as the substrate. ... -
Development of a solar desalination plant
(Geological Soc South Africa, 2016)South Africa is predominantly a water scarce country with many parts having limited access to water. Water quality is an additional stressor affecting available water supply. In the semi-arid to arid regions of the country, ... -
The development of a systems development methodology for location-based games
(ACM, 2018)Currently, there is a lack of systems development methodologies (SDMs) suitable for the development of location-based games. This research introduced a newly developed SDM to aid in the development process of location-based ... -
