Erratum to: Post-orogenic shoshonitic magmas of the Yzerfontein pluton, South Africa: the 'smoking gun' of mantle melting and crustal growth during Cape granite genesis?
(Springer Verlag, 2017)The published version of the original paper contained a Sr isotope analysis of Hornblende-pyroxene quartz monzodiorite sample H25, from the shoshonitic part of the Cambrian Yzerfontein pluton on the West Coast in South ... -
Erratum: The frequency of very young galaxies in the local Universe: II. The view from SDSS spectra
(Oxford University Press, 2020)Only a handful of galaxies in the local Universe appear to be very young. We estimate the fraction of very young galaxies (VYGs), defined as those with more than half their stellar masses formed within the last Gyr. We ... -
Essential metal and metalloid elements in the Philippi Horticultural area, and their uptake into selected vegetable crops
(Taylor & Francis, 2018)This study evaluated Co, Cr, Mn, Ni, Se, Sn and V status in the soils of the PHA, as well as the vegetables produced on these soils. We also determined the agronomic sources of these elements to the soils in the PHA. ... -
Establishing a pharmacist–prescriber partnership in publicly funded primary healthcare clinics to optimisantibiotic prescribing in the Western Cape: An exploratory study
(Taylor & Francis, 2020)Promoting evidence-based antibiotic prescribing through successful antimicrobial stewardship (AMS) programmes is critical to preserving the effectiveness of antibiotics for common infections in primary care. This requires ... -
Establishing a pharmacist–prescriber partnership in publicly funded primary healthcare clinics to optimise antibiotic prescribing in the Western Cape: An exploratory study
(AOSIS, 2020)Promoting evidence-based antibiotic prescribing through successful antimicrobial stewardship (AMS) programmes is critical to preserving the effectiveness of antibiotics for common infections in primary care. This requires ... -
Establishing minion sequencing and genome assembly procedures for the analysis of the rooibos (aspalathus linearis) genome
(MDPI, 2022)While plant genome analysis is gaining speed worldwide, few plant genomes have been sequenced and analyzed on the African continent. Yet, this information holds the potential to transform diverse industries as it unlocks ... -
Establishing provenance from highly impoverished heavy mineral suites: Detrital apatite and zircon geochronology of central North Sea Triassic sandstones
(MDPI, 2022-12-30)A study of Triassic sandstones in the central North Sea, UK, has shown that combined detrital zircon and apatite geochronology and apatite trace element analysis is a powerful tool for reconstructing provenance for ... -
Establishing the link between urban land cover change and the proliferation of aquatic hyacinth (Eichhornia crassipes) in Harare Metropolitan, Zimbabwe
(Elsevier, 2018)Urbangrowthisakeyprocessaffectingthefunctioningofnaturalecosystems,andconsequentlythegloballand-surface process. This work aimed at establishing the link between land cover changes around HarareMetropolitancityandtheprol ... -
Establishment of the African Medicines Agency: Progress, challenges and regulatory readiness
(Springer Nature, 2021)Insufcient access to quality, safe, efcacious and afordable medical products in Africa has posed a signifcant challenge to public health for decades. In part, this is attributed to weak or absent policies and regulatory ... -
Estimating above-ground biomass in sub-tropical buffer zone community Forests, Nepal, using Sentinel 2 data
(MDPI, 2018)Accurate assessment of above-ground biomass (AGB) is important for the sustainable management of forests, especially buffer zone (areas within the protected area, where restrictions are placed upon resource use and special ... -
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 ... -
Estimating the electron energy and the strength of the electric field within sprites using ground-based optical data observed over South African storms
(Elsevier, 2021)We present a new simplified method to estimate the characteristic electron energy and electric field within a mesospheric transient luminous event using ground-based calibrated and filtered optical data. We assume ... -
Estimation of recharge using a revised CRD method
(Water Research Commission, 2001)The cumulative rainfall departure (CRD) method, based on the water-balance principle, is often used for mimicking of water level fluctuations. Because of its simplicity and minimal requirement of spatial data, the CRD ... -
Estimation of the coherence time of stochastic oscillations from modest samples
(Oxford University Press, 2012)‘Quasi-periodic’ or ‘solar-like’ oscillations can be described by three parameters – a characteristic frequency, a coherence time (or ‘quality factor’) and the variance of the random driving process. This paper is concerned ... -
An estuary ecosystem classification that encompasses biogeography and a high diversity of types in support of protection and management
(Taylor & Francis, 2020)For nearly three decades, the Whitfield (1992) characterisation scheme served as a reference framework to type South African estuaries. We outline a revised ecosystem classification scheme that incorporates biogeographical ... -
Ethanol oxidation activity and structure of carbon-supported Pt-modified PdSn-SnO2 influenced by different stabilizers
(Elsevier, 2013)PdSn-SnO2 nanoparticles supported on Vulcan XC-72 carbon were synthesized by chemical reduction in the presence of three different stabilizing agents: ethylene diamine tetra-acetic acid (EDTA), sodium citrate (Nacitrate) ... -

Ethics and mono-disciplinarity: positivism, informed consent and informed participation
(Elsevier, 2005)There are a number of pressures on researchers in academia and industry to behave unethically or compromise their ethical standards, for instance in order to obtain funding or publish frequently. In this paper a case study ... -
