Crystal structure, hirshfeld surface analysis and dft studies of 5-(adamantan-1-yl)-3-[(4-chlorobenzyl)sulfanyl]-4-methyl-4h-1,2,4-triazole, a potential 11β-hsd1 inhibitor
(Scientific Reports, 2019)5-(Adamantan-1-yl)-3-[(4-chlorobenzyl)sulfanyl]-4-methyl-4H-1,2,4-triazole (4) was identified as a potential 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) inhibitor and this paper describes the in-depth structural ... -
Comparing galaxy clustering in horizon-agn simulated light-cone mocks and video observations
(Oxford academic, 2019)Hydrodynamical cosmological simulations have recently made great advances in reproducing galaxy mass assembly over cosmic time – as often quantified from the comparison of their predicted stellar mass functions to observed ... -
Mergers, starbursts, and quenching in the SIMBA simulation
(Oxford Academic, 2019)We use the SIMBAcosmological galaxy formation simulation to investigate the relationship between major mergers (4:1), starbursts, and galaxy quenching. Mergers are identified via sudden jumps in stellar mass M∗ well above ... -
Community healthcare mesh network engineering in white space frequencies
(Institute of Electrical and Electronics Engineers, 2019)The transition from analog to digital television has availed new spectrum called white space, which can be used to boost the capacity of wireless networks on an opportunistic basis. One sector in which there is a need to ... -
Quantifying the contribution of riparian total evaporation to streamflow transmission losses: Preliminary investigations along the Groot Letaba river
(Elsevier, 2019-11-08)The Groot Letaba River, situated in the semi-arid north-eastern region of South Africa is an example of a river system in which the uncertainty associated with transmission losses (TL) has limited the effective management ... -
Comparing galaxy clustering in horizon-agn simulated light-cone mocks and video observations
(Oxford University Press, 2019-04-12)Hydrodynamical cosmological simulations have recently made great advances in reproducing galaxy mass assembly over cosmic time – as often quantified from the comparison of their predicted stellar mass functions to observed ... -
Mergers, starbursts, and quenching in the SIMBA simulation
(MNRAS, 2019-07-29)We use the SIMBAcosmological galaxy formation simulation to investigate the relationship between major mergers ( 4:1), starbursts, and galaxy quenching. Mergers are identified via sudden jumps in stellar mass M∗ well ... -
Deeper knowledge of shallow waters: reviewing the invertebrate fauna of southern African temporary wetlands
(Spring Nature Limited, 2018)Temporary lentic wetlands are becoming increasingly recognised for their collective role in contributing to biodiversity at the landscape scale. In southern Africa, a region with a high density of such wetlands, ... -
Astronomy for Development – A story from South Africa
(UWC, 2021)In this article we describe the recent history of astronomy in South Africa from the perspective of development. We describe how all major astronomy initiatives have carried a component of development with them, be it ... -
Inclusive education and research through African Network of Women in Astronomy and STEM for GIRLS in Ethiopia initiatives
(UWC, 2021)The African Network of Women in Astronomy and STEM for GIRLS in Ethiopia initiatives have been established with aim to strengthen the participation of girls and women in astronomy and science in Africa and Ethiopia. We ... -
Comparative in vitro transportation of pentamidine across the blood-brain barrier using polycaprolactone nanoparticles and phosphatidylcholine liposomes
(UWC, 2019)Nanoparticles (NPs) have gained importance in addressing drug delivery challenges across biological barriers. Here, we reformulated pentamidine, a drug used to treat Human African Trypanosomiasis (HAT) in polymer based ... -
The Utility of the Upcoming HyspIRI’s Simulated Spectral Settings in Detecting Maize Gray Leafy Spot in Relation to Sentinel-2 MSI, VENµS, and Landsat 8 OLI Sensors
(UWC, 2019)Abstract: Considering the high maize yield loses caused by incidences of disease, as well as incomprehensive monitoring initiatives in crop farming, there is a need for spatially explicit, cost-effective, and consistent ... -
Effect of the annealing atmosphere on the layer interdiffusion in Pd/Ti/Pd multilayer stacks deposited on pure Ti and Ti-alloy substrates
(University of the Western Cape, 2019)Pd(50 nm)/Ti(25 nm)/Pd(50 nm) multilayer stack has been deposited on Ti and Ti6Al4V substrates; we have studied the intermixing of layers upon annealing at the hydrogenation temperature of 550 °C, under vacuum, H/Ar gas ... -
Mechanisms of interference and exploitation competition in a guild of encrusting algae along a South African rocky shore
(University of the Western Cape, 2019)Within the marine benthos, space is considered an absolute requirement that is often in limited supply. The often-low availability of this essential resource causes species to interact competitively through mechanisms of ... -
A tale of two habitats: preliminary comparison of fish abundance and diversity between saltmarsh- and mangrove-dominated creeks in the Nahoon Estuary, South Africa
(University of the Western Cape, 2019)A preliminary assessment of abundance and richness of fishes utilising saltmarsh and mangrove habitats in the Nahoon Estuary, situated on the eastern coast of South Africa, was undertaken during July 2017. The structural ... -
Energy-momentum tensor and helicity for gauge fields coupled to a pseudoscalar inflaton
(University of the Western Cape, 2019)We study the energy-momentum tensor and helicity of gauge fields coupled through $g \phi F \tilde{F}/4$ to a pseudo-scalar field $\phi$ driving inflation. Under the assumption of a constant time derivative of the background ... -
Rotational structures in 196Hg
(University of the Western Cape, 2019)High spin states in 196 Hg were populated in the 198 Pt (α,6n) reaction at 65 MeV and γ −γ coincidence measurements were performed using the AFRODITE array at iThemba LABS. The level scheme was extended and new rotational ... -
High Concussion Rate in Student Community Rugby Union Players During the 2018 Season: Implications for Future Research Directions
(UWC, 2019)Collision sports, such as Rugby Union (“Rugby”) have a particularly high risk of injury. Of all injuries common to collision sports, concussions have received the most attention due to the potentially negative cognitive ... -
Policy implementation for water resources protection: Assessing spatio-temporal trends of results from process-based outcomes of resource-directed measures projects in South Africa
