Preface Metamorphism and Orogenic belts—response from micro- to macro-scale
(Springerlink, 2019)The geological toolbox for the analysis of orogenic processes has seen substantial additions over the recent decades. Major advances have been made in the ability to simulate geological conditions and processes by computer ... -
Surveys with small optical telescopes
(Oxford academic, 2019)odern astrophysics owes its existence to small-telescope surveys dating back to the 18th century, for example Flamsteed (1725). In the 19th century, Argelander’s survey based on visual observations with small telescopes and ... -
Nanotechnology-based strategies for treatment of obesity, cancer and anti-microbial resistance: Highlights of the Department of Science and Innovation/mintek Nanotechnology Innovation centre biolabels research node at the University of the Western Cape
(MDPI, 2022)Nanotechnology has recently received much interest in various fields, including medicine. South Africa (SA) was the first country in Africa to adopt the technology with the aim of enhancing the national bio-economy and ... -
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 ... -
Semi-analytic forecasts for jwst – ii. Physical properties and scaling relations for galaxies at z = 4–10
(Oxford academic, 2019)The long anticipated James Webb Space Telescope (JWST) will be able to directly detect large samples of galaxies at very high redshift. Using the well-established, computationally efficient Santa Cruz semi-analytic model, ... -
An economic feasibility model for sustainable 5G networks in rural dwellings of South Africa
(MDPI, 2022)Numerous factors have shown Internet-based technology to be a key enabler in achieving the sustainable development goals (SDG), as well as narrowing the divide between the global north and south. For instance, smart ... -
Using the water balance approach to understand pool dynamics along non-perennial rivers in the semi-arid areas of South Africa
(Elsevier, 2022)The Touws River in the Klein Karoo region of South Africa Study focus: This study sought to improve the understanding of pool dynamics along non-perennial rivers (NPRs) by utilising the water balance approach to assess the ... -
Factors associated with mothers’ health care‑seeking behaviours for childhood fever in Burkina Faso: Findings from repeated cross‑sectional household surveys
(BMC, 2022)Fever is one of the most frequent reasons for paediatric consultations in Burkina Faso, but health careseeking behaviours and the factors associated with health care-seeking in the event of childhood fever are poorly documented. ... -
Probing primordial features with the primary CMB
(Elsevier, 2019)We propose to study the imprint of features in the primordial power spectrum with the primary CMB after the subtraction of the reconstructed ISW signal from the observed CMB temperature angular power spectrum. We consider ... -
UniQ-Typer ™ Y-10 genotyping in South African populations: novel alleles, sequence variation and allelic ladder updates
(Elsevier, 2019)DNA profiling the male specific region on the Y-chromosome is fundamental to forensic practise. It is recognised as a powerful tool for sexual assault investigations for resolving the male DNA components, for familial ... -
Crystal structure, Hirshfeld surface analysis and DFT studies of 5-(adamantan-1-yl)-3-[(4- chlorobenzyl)sulfanyl]-4-methyl4H-1,2,4-triazole, a potential 11βHSD1 inhibitor
(Scientific Reports, 2019)5-(Adamantan-1-yl)-3-[(4-chlorobenzyl)sulfanyl]-4-methyl-4H-1,2,4-triazole (4) was identifed as a potential 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) inhibitor and this paper describes the in-depth structural ... -
Happy Feet in a Hostile World? The Future of Penguins Depends on Proactive Management of Current and Expected Threats
(2019)Penguins face a wide range of threats. Most observed population changes have been negative and have happened over the last 60 years. Today, populations of 11 penguin species are decreasing. Here we present a review that ... -
Assessing edge effect on the spatial distribution of selected forest biochemical properties derived using the worldview data in Dukuduku forests, South Africa
(Wiley, 2019)This work explores the potential of the high‐resolution WorldView‐2 sensor in quan‐tifying edge effects on the spatial distribution of selected forest biochemical proper‐ties in fragmented Dukuduku forest in KwaZulu‐Natal, ... -
Hierarchiral 4-tetranitro copper(II)phthalocyanine based metal organic framework hybrid composite with improved electrocatalytic efficiency towards hydrogen evolution reaction
(Elsivier, 2019)A novel hybrid-hybrid nanocomposite based on 4-tetranitro copper(II)phthalocyanine (TNCuPc) grown on metal organic frameworks (MOF) as a noble metal-free catalyst for hydrogen evolution reaction (HER) was developed by a ... -
Multifilter time-series observations of three short period ATLAS variable stars
(Oxford University Press, 2019-09)The ‘Asteroid Terrestrial-impact Last Alert System’ discovered hundreds of thousands of new candidate variable stars. Follow-up observations of three of these are reported in this paper. The targets were selected on the ... -
