Will a rising sea sink some estuarine wetland ecosystems?
(Elsevier, 2016)Sea-level rise associated with climate change presents a major challenge to plant diversity and ecosystem service provision in coastal wetlands. In this study, we investigate the effect of sea-level rise on benthos, ... -
Will climate warming exceed lethal photosynthetic temperature thresholds of lichens in a southern African arid region?
(Wiley, 2013)Predicted elevated temperatures and a shift from a winter to summer rainfall pattern associated with global warming could result in the exposure of hydrated lichens during summer to more numerous temperature extremes that ... -
Winter is coming: A southern hemisphere perspective of the environmental drivers of sars-cov-2 and the potential seasonality of covid-19
(MPDI, 2020)SARS-CoV-2 virus infections in humans were first reported in December 2019, the boreal winter. The resulting COVID-19 pandemic was declared by the WHO in March 2020. By July 2020, COVID-19 was present in 213 countries and ... -
The WISE Extended Source Catalog (WXSC). I. The 100 Largest Galaxies
(University of the Western Cape, 2019)We present mid-infrared photometry and measured global properties of the 100 largest galaxies in the sky, including the well-studied Magellanic Clouds, Local Group galaxies M31 and M33, the Fornax and Virgo galaxy cluster ... -
Woman-centred care in childbirth: a concept analysis (Part 1)
(AOSIS OpenJournals, 2013)'Woman-centred care' in childbirth is a process in which a woman makes choices and is involved in and has control over her care and relationship with her midwife. The aim of this paper is to study the concept of woman-centred ... -
Women's education and health inequalities in under-five mortality in selected sub-Saharan African countries, 1990–2015
(PLOS, 2016)The aim of the study was to analyse trends in the relationship between mother’s educational level and mortality of children under the year of five in Sub-Saharan Africa, from 1990 to 2015.Data used in this study came ... -
Wood-derived, monolithic chainmail electrocatalyst for biomass-assisted hydrogen production
(Wiley, 2023)The chainmail catalyst by encapsulating an active species within the carbon support is a well-established concept to endorse extraordinary stability for catalytic reactions under harsh conditions. Conventional chainmail ... -
Work participation and disabilities in India
(Kamla-Raj Enterprises, 2009)United Nations General Assembly in 1976 proclaimed 1981 as the International Year of the Disable Persons. Persons with disabilities are enthusiastic to overcome the social and economic barriers. In the present paper an ... -
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 ... -
X-ray emission from hot gas in galaxy groups and clusters in SIMBA
(Oxford University Press, 2020-08-31)We examine X-ray scaling relations for massive haloes (M500 > 1012.3 M) in the SIMBA galaxy formation simulation. The X-ray luminosity, LX versus M500 has power-law slopes ≈5 3 and ≈8 3 above and below 1013.5 M, deviating ... -
The XXL survey XLII. Detection and characterization of the galaxy population of distant galaxy clusters in the XXL-N/VIDEO field: A tale of variety
(ESO, 2020)Context. Distant galaxy clusters provide an effective laboratory in which to study galaxy evolution in dense environments and at early cosmic times. Aims. We aim to identify distant galaxy clusters as extended X-ray sources ... -
Yeast supplementation alleviates the negative effects of greywater irrigation on lettuce and maize
(South African Water Research Commission, 2022)Water scarcity has led to increased use of wastewater, particularly greywater, for crop irrigation. This study investigated whether the addition of yeast can alleviate the potential negative effects of greywater use on ... -
You use seaweeds for that?
(Botanical Society of South Africa, 2006)Introduction: The word seaweed is commonly used, yet to refer to these marine algae as 'weeds' is very far from the truth. Together with microscopic algae called phytoplankton and other photosynthetic organisms, seaweeds ... -
Zebrafish behavioral response to ivermectin: Insights into potential neurological risk
(Elsevier, 2022)Ivermectin is a well‐known and widely used anti‐parasitic drug. Recently, in vitro data suggest anti‐viral effi- cacy of the drug, albeit at much higher concentrations than currently approved. Despite warnings by ... -
