Spray‐pyrolyzed Cd‐substituted kesterite thin‐films for photovoltaic applications: Post annealing conditions and property studies
(Elsevier, 2023)Kesterite materials were investigated for their suitability as absorber layers for thin-film photovoltaic cells. Thin- films of copper cadmium zinc tin sulfide (Cu2CdxZn1-xSnS4) were prepared by spray pyrolysis on soda-lime ... -
Sputtered Si and Mg doped hydroxyapatite for biomedical applications
(IOP Publishing, 2018-01-30)Hydroxyapatite (HAP) coatings are applied on metallic implant materials to combine mechanical properties of metallic material with bioactivity abilities of HAP ceramic. In this study, HAP coatings with additions of Si ... -
The stability and anti-angiogenic properties of titanium dioxide nanoparticles (tio2nps) using caco-2 cells
(MDPI, 2022)Titanium dioxide nanoparticles (TiO2NPs) are found in a wide range of products such as sunscreen, paints, toothpaste and cosmetics due to their white pigment and high refractive index. These wide-ranging applications ... -
Stability of an SEIR epidemic model with indepenent stochastic perturbations
(Elsevier, 2013)For an epidemic model of the type mentioned, we prove a theorem on almost sure exponential stability of the disease-free equilibrium. For small values of the diffusion parameter, σ, we describe the stability of the disease ... -
The stability of learners’ choices for real-life situations to be used in mathematics
(Taylor & Francis, 2013)One of the efforts to improve and enhance the performance and achievement in mathematics of learners is the incorporation of life-related contexts in mathematics teaching and assessments. These contexts are normally, with ... -
Stacked reverberation mapping
(Oxford University Press, 2013)Over the past 20 years reverberation mapping has proved one of the most successful techniques for studying the local (<1 pc) environment of supermassive black holes that drive active galactic nuclei. Key successes of ... -
STACKing the odds for adolescent survival: health service factors associated with full retention in care and adherence amongst adolescents living with HIV in South Africa
(Wiley Open Access, 2018)INTRODUCTION: There are two million HIV-positive adolescents in southern Africa, and this group has low retention in care and high mortality. There is almost no evidence to identify which healthcare factors can improve ... -
Staff development strategies for publication in Faculty of Community and Health Science at UWC: a short report
(University of the Western Cape, 2010)INTRODUCTION: Strategies for improving the publication output of academics are an essential component of research directives at tertiary institutions. The aim of this report was to highlight the effects of a writing ... -

Staging historical argument: History I at the University of the Western Cape
(Routledge, 1996)This article focuses on the lecture-room debates which have been the central feature of the first-year history course at the University of the Western Cape (UWC) since 1993. The UWC History Department takes the position ... -
Staircase or safety net? Examining the meaning and functioning of RDP house ownership among beneficiaries: A case study of Klapmuts
(University of the Western Cape, 2020)Recognising the apartheid legacy of inaccess to housing and property for the majority of black South Africans, the Constitution entrenches rights of access to housing and property. Since 1994, one of the main ways the ... -
Stakeholder-derived recommendations and actions to support deep-reef conservation in the Western Indian Ocean
(Wiley, 2022)Deep reefs below 30mprovide essential ecosystem services for ocean health and human well-being such as food security and climate change resilience. Yet, deep reefs remain poorly researched and largely unprotected, including ... -
Stakeholders’ community-engaged teaching and learning experiences at three universities in South Africa
(Health and Medical Publishing Group, 2021)Transformation forces in South African (SA) higher education and beyond have called for incorporation of community engagement into higher education. Specifically, the SA white paper 3 that informed the Higher Education ... -

The star formation rates of QSOs
(Royal Astronomical Society, 2022)We examine the far-IR properties of a sample of 5391 optically selected QSOs in the 0.5 < z < 2.65 redshift range down to log [νLν,2500(erg/s)] > 44.7, using SPIRE data from Herschel-ATLAS. We split the sample in a grid ... -
The star-formation history of mass-selected galaxies from the VIDEO survey
(Oxford University Press, 2014)We measure star formation rates (SFRs) and specific SFRs (SSFRs) of Ks-selected galaxies from the VISTA Deep Extragalactic Observations survey by stacking 1.4 GHz Very Large Array data. We split the sample, which spans 0 ... -
