(Adis, 2022)The medicines regulatory landscape in Africa is undergoing transformation with at least two countries having National Medicines Regulatory Authorities (NRAs) that operate at World Health Organization (WHO) maturity level ... -
Deep extragalactic visible legacy survey (DEVILS):Evolution of the σsFR-M relation and implications for self-regulated star formation
(University of the Western Cape, 2022)We present the evolution of the star formation dispersion–stellar mass relation ( σSFR –M ) in the DEVILS D10 region using new measurements derived using the PROSPECT spectral energy distribution fitting code. We find ... -
COSMOS2020: A panchromatic view of the universe to z ∼ 10 from two complementary catalogs
(University of the Western Cape, 2022)The Cosmic Evolution Survey (COSMOS) has become a cornerstone of extragalactic astronomy. Since the last public catalog in 2015, a wealth of new imaging and spectroscopic data have been collected in the COSMOS field. This ... -
Probing the nature of the conjectured low-spin wobbling bands in atomic nuclei
(Elsevier, 2022)The precession of an atomic nucleus can be approximately described as wobbling motion, arising from the coupling of a rotation and a harmonic vibration. Recently, a number of wobbling bands were reported at low spin, which ... -
Multimodality and new materialism in science learning: Exploring insights from an introductory physics lesson
(Unisa Press, 2021)Science disciplines are inherently multimodal, involving written and spoken language, bodily gestures, symbols, diagrams, sketches, simulation and mathematical formalism. Studies have shown that ... -
Parental reporting of adverse drug reactions in South Africa: An online survey
(AOSIS, 2021)The high incidence of adverse drug reactions (ADRs) in children is of global concern. Enhancing the reporting of ADRs could contribute to making safer medicines available to children.To assess parents’ awareness of ... -
In vitro effects of aqueous extract of unfermented rooibos on human spermatozoa
(Wiley, 2022)The inability to conceive is a baleful experience for thousands of couples worldwide. Among different well-known reproductive techniques, medicinal plants have been utilized to treat male infertility. Medicinal plants, ... -
Africa 3: A continental network model to enable the African fourth industrial revolution
(IEEE, 2020)It is widely recognised that collaboration can help fast-track the development of countries in Africa. Leveraging on the fourth industrial revolution, Africa can achieve accelerated development in health care services, ... -
Hydrogeochemical characteristics and evaluation of groundwater quality for domestic and irrigation purposes: A case study of the Heuningnes Catchment, Western Cape Province, South Africa
(Springer, 2020)Knowing the quality of water is imperative if the water is meant for drinking or agricultural purposes. The spatial and temporal groundwater quality in the Heuningnes Catchment was investigated, and its appropriateness ... -
Origin, Migration, and Reproduction of Indigenous Domestic Animals with Special Reference to Their Sperm Quality
(MDPI, 2022): Indigenous domestic animals such as cattle, sheep, goats, pigs, and chickens have a natural resistance to endo- and ecto-parasites and are tolerant in terms of harsh environmental conditions. These species orginated ... -
Mathematical modeling and impact analysis of the use of COVID alert SA app
