Certification or qualification: an analysis of formal and non-formal higher education in South Africa
(Faerie Glen, South Africa, 2012) -
Cervical squamous intraepithelial lesions and associated cervical infections in an HIV-positive population in rural Mpumalanga, South Africa
(Wiley, 2013)Background: The incidences of genital human papillomavirus (HPV) infection, associated squamous intraepithelial lesions and cervical squamous cell carcinoma are significantly increased in HIV-positive women. The role of ... -
CFD analysis of thermal dispersion in a structured packed bed
(SACAM, 2018)Packed beds are generally modelled in a partial manner to avoid computational costs. This implies that only a small portion of the representative bed is modelled explicitly in CFD simulations, usually by assuming ... -
CFD and systems thermal-hydraulic analysis in the design and safety assessment of high-temperature reactors
(Woodhead Publishing, 2019)An overview is provided of the role of the various levels of CFD in the different stages of the design, analysis and evaluation of very-high-temperature reactor (VHTR) systems and molten salt reactor (MSR) systems. The ... -
CFD applications in the Pebble Bed Modular Reactor Project: a decade of progress
(Elsevier, 2011)Of all the systems and components that have to be designed for a nuclear plant, the Reactor Unit is the most significant since it is at the very heart of the plant. At Pebble Bed Modular Reactor (Pty) Ltd. (PBMR), the ... -
CFD modeling of particle charging and collection in electrostatic precipitators
(Elsevier, 2016)A CFD model was developed to describe the particle laden gas flow through an ESP, particle charging and collection. The corona discharge was modeled using the open source software OpenFOAM to solve the Poison and charge ... -
CFD simulation and experimental study of a hydrogen leak in a semi-closed space with the purpose of risk mitigation
(Elsevier, 2020)Computational fluid dynamics (CFD) methods were used to analyze hydrogen leakage in a semi-closed ventilation facility. The goal of the research was to apply numerical simulations to verify hydrogen distribution in the ... -
CFD simulation of an industrial wet flue gas desulfurization spray tower: a comprehensive model with special atttention devoted to the modeling of absorption and chemical reactions
(International Pittsburgh Coal Conference, 2016) -
CGE or SAM? Ensuring quality information for decision-making
(AJHTL, 2015)The purpose of this paper is to conduct an economic assessment of the Aardklop National Arts Festival (hereafter referred to as Aardklop) by means of applying both the SAM and CGE methods, in order to ensure quality ... -
The challenge of conserving amphibian megadiversity in Madagascar
(Public Library of Science (PLOS), 2008) -
The Challenge: Quality Enhancement in Teaching– How do We Know We are Making Progress?
(IACSIT Press, 2014)In 2014 the Council for Higher Education in South Africa launched a national Quality Enhancement Project (QEP). The aim of the project is to improve student success both at individual Higher Education Institutions and in ... -
A challenged sympathetic system is associated with retinal vascular calibre in a black male cohort: the SABPA Study
(Intech, 2016)Sympathetic system hyperactivity and depression are related to cardiac remodelling in Black men. We investigated whether sympathetic system hyperactivity and depressive symptoms are related to retinal vascular dysregulation. ... -
Challenges and emerging solutions to the land-based plastic waste issue in Africa
(Elsevier, 2018)In recent years, there has been a tremendous increase in work that focuses on the amount and types of waste entering the marine environment from multiple geographies around the world. To date, however, there are few reports ... -
Challenges and issues in drug utilization research identified from the Latin American and African regions
(Wiley, 2018)Background: Despite advancements in drug utilization research (DUR), these have not been universal. Some regions such as the Latin America (LatAm) and African regions are facing challenges that are impeding the development ... -
Challenges and opportunities for biological mass spectrometry core facilities in the developing world
(The Association of Biomolecular Resource Facilities, 2018)The developing world is seeing rapid growth in the availability of biological mass spectrometry (MS), particularly through core facilities. As proteomics and metabolomics becomes locally feasible for investigators in these ... -
Challenges and opportunities for public administration in the Fourth Industrial Revolution
(African Consortium of Public Administration (ACPA), 2017)The world is at the brink of the much anticipated digital transformation orchestrated by the Fourth Industrial Revolution. Despite the perceived benefits of increased efficiency and effectiveness in service delivery, the ... -
Challenges and opportunities related to quality distance higher education in Zimbabwe
(UNISA Press, 2016)Zimbabwe has managed to respond to the movement in support of UNESCO'S lifelong learning concept and strategy that seeks to widen and deepen access to higher education through distance education initiatives. Despite the ... -
The challenges and perceptions of community caregivers with regard to antiretroviral treatment adherence of patients: a phenomenological study
(Univ Stellenbosch, 2017)Although there is no cure for HIV and AIDS, antiretroviral treatment has transformed this disease into a manageable chronic illness. Relatively little is known about the experiences and psychosocial challenges that community ...
