Estimating leopard density across the highly modified human-dominated landscape of the Western Cape, South Africa
(Cambridge University, 2021)Apex predators play a critical role in maintaining the health of ecosystems but are highly susceptible to habitat degradation and loss caused by land-use changes, and to anthropogenic mortality. The leopard Panthera ... -
Organic nanostructured materials for sustainable application in next generation solar cells
(MPDI, 2021)Meeting our current energy demands requires a reliable and efficient renewable energy source that will bring balance between power generation and energy consumption. Organic photovoltaic cells (OPVs), perovskite solar ... -
A review of the processes associated with the removal of oil in water pollution
(MPDI, 2021)Water plays an essential role in production and refining processes. Many industries that use petrochemicals also require water, especially for cleaning purposes. The wastewaters released by these processes are often rich ... -
Prediction of human-Bacillus anthracis protein–protein interactions using multi-layer neural network
(Oxford University Press, 2018)Triplet amino acids have successfully been included in feature selection to predict human-HPV protein-protein interactions (PPI). The utility of supervised learning methods is curtailed due to experimental data not being ... -
The sixth edition of the WHO manual for human semen analysis: A critical review and SWOT analysis
(MDPI, 2021)Semen analysis is the cornerstone of male fertility evaluation with WHO guidelines providing the basis for procedural standardization and reference values worldwide. The first WHO manual was published in 1980, and five ... -
Wound healing activities and potential of selected african medicinal plants and their synthesized biogenic nanoparticles
(2021-11)In Africa, medicinal plants have been traditionally used as a source of medicine for centuries. To date, African medicinal plants continue to play a significant role in the treatment of wounds. Chronic wounds are associated ... -
Radio spectral properties of star-forming galaxies in the MIGHTEE-COSMOS field and their impact on the far-infrared-radio correlation
(Oxford University Press, 2021)We study the radio spectral properties of 2094 star-forming galaxies (SFGs) by combining our early science data from theMeerKAT International GHz Tiered Extragalactic Exploration (MIGHTEE) survey with VLA, GMRT ... -
Determinants of women’s preferred and actual abortion provision locations in Nigeri
(Springer, 2021)Background: Unsafe abortion remains a leading cause of maternal mortality globally. Many factors can infuence women’s decisions around where to seek abortion care; however, little research has been done on abortion care ... -
Discovery of 9-phenylacridinediones as highly selective butyrylcholinesterase inhibitors through structure-based virtual screening
(Elsevier, 2020)Butyrylcholinesterase (BuChE) is considered a promising drug target as it plays an important role in the pro-gression of late stage Alzheimer’s disease (AD). Two compound libraries were selected and 64 124 aminecontaining ... -
Status of sperm functionality assessment in wildlife species: From fish to primates
(2021-05)(1) Background: in order to propagate wildlife species (covering the whole spectrum from species suitable for aquaculture to endangered species), it is important to have a good understanding of the quality of their sperm, ... -
Improving quality-of-service in cloud/fog computing through efficient resource allocation
(MPDI, 2019)Recently, a massive migration of enterprise applications to the cloud has been recorded in the IT world. One of the challenges of cloud computing is Quality-of-Service management, which includes the adoption of appropriate ... -
Information security at South African universities-Implications for biomedical research
(Oxford University Press, 2020)In South Africa, a similar regulation strategy to the European Union General Data Protection Regulation, called the Protection of Personal Information Act (No 4 of 2013) (POPIA), will be implemented, with a view to ... -
Nanostructured Mn-doped CeO2 thin films with enhanced electrochemical properties for pseudocapacitive applications
(Elsevier, 2021-06)Cerium oxides with variable oxidation states, high interfacial charge transfer rate have demonstrated to be a potential pseudocapacitive material. In this paper, we present the structural and electrochemical properties of ... -
On the road to per cent accuracy - V. The non-linear power spectrum beyond ΛCDM with massive neutrinos and baryonic feedback
(Oxford University Press, 2021-12)In the context of forthcoming galaxy surveys, to ensure unbiased constraints on cosmology and gravity when using non-linear structure information, per cent-level accuracy is required when modelling the power spectrum. This ... -
Leveraging Google Earth Engine platform to characterize and map small seasonal wetlands in the semi-arid environments of South Africa
(Elsevier, 2021-07)Although significant scientific research strides have been made in mapping the spatial extents and ecohydrological dynamics of wetlands in semi-arid environments, the focus on small wetlands remains a challenge. This is ... -
Relevance of leukocytospermia and semen culture and its true place in diagnosing and treating male infertility
(Korean Society for Sexual Medicine and Andrology, 2021)The current WHO 2010 manual for human semen analysis defines leukocytospermia as the presence of peroxidase-positive leukocytes at a concentration >1×106 /mL of semen. Granular leukocytes when activated are capable of ... -
