Magnetogenesis in cyclical Universe
(IOP Publishing, 2018)We propose a simple solution to the magnetogenesis problem based on cyclic cosmology. It is demonstrated that magnetic fields, of sufficient strengths to account for the present observational bounds, can be created in ... -
Whey protein hydrolysate supplementation accelerates recovery from exercise-induced muscle damage in females
(Canadian Science Publishing, 2018)A number of different forms of protein and their analogues have been investigated for their efficacy in ameliorating exercise-induced muscle damage (EIMD) and recovery. Preliminary data regarding whey protein hydrolysate ... -
A pilot study investigating reactive oxygen species production in capillary blood after a marathon and the influence of an antioxidant-rich beetroot juice
(Canadian Science Publishing, 2018)We report that reactive oxygen species (ROS), as measured in capillary blood taken from the finger-tip, increased after a marathon (+128% P < 0.01; effect size = 1.17), indicating that this collection method might be useful ... -
Ipsilateral corticomotor responses are confined to the homologous muscle following cross-education of muscular strength
(Canadian Science Publishing, 2018)Cross-education of strength occurs when strength-training 1 limb increases the strength of the untrained limb and is restricted to the untrained homologous muscle. Cortical circuits located ipsilateral to the trained limb ... -
Alain Dubois’ contributions to African amphibian nomenclature
(ISSCA, 2018)Alain Dubois has made important contributions to our understanding of African amphibians. His 1981 interpretations based only on earlier literature include the recognition of a series of subfamiles in the Ranidae. Later ... -
Neo-mercantilism as development ideology: a conceptual approach to rethink the space economy in Africa
(Taylor & Francis, 2018)Since the mid-15th century, the space economy in Africa has assumed an imperial outlook under the influence of European mercantilism. It was the era that unfettered capitalism prevailed as economic orthodoxy for control ... -
Groundwater monitoring during underground coal gasification
(SAIMM, 2018)Underground coal gasification (UCG) is a fast-emerging, in situ mining technology that provides access to low-cost energy through the utilization of coal reserves that are currently not technically or economically exploitable ... -
Analysis of metal-laden water via portable X-ray fluorescence spectrometry
(Elsevier, 2018)A rapid method for in-situ elemental composition analysis of metal-laden water would be indispensable for studying polluted water. Current analytical lab methods to determine water quality include flame atomic absorption ... -
A tripartite approach to ensure municipal service delivery. The case of a mining town in South Africa
(CCAU, 2019)Postmasburg, a small mining town, has been an agricultural centre for the past 120 years, the iron ore mining being the only diversifying factor to the local economy. Mining endeavours resulted in the traditional boom-town ... -
Reproductive potential of South African thermophilic Meloidogyne populations, with special reference to Meloidogyne enterolobii
(Brill, 2019)Variability in the reproductive potential of Meloidogyne spp. is crucial to design suitable nematode management strategies. The reproductive potential of nine South African single-species Meloidogyne populations, M. ... -
New gnathiid isopod crustaceans (Cymothoida) from Heron Island and Wistari Reef, southern Great Barrier Reef
(Magnolia Press, 2019)Eleven species including six new species of Gnathiidae (Crustacea, Isopoda, Cymothoida) are reported from the Heron Island and Wistari Reef, Capricorn Group, southern Great Barrier Reef: Elaphognathia queenslandica sp. ... -
Exploring levels of egg parasitism and variation in egg cuticular chemistry in different Clavigralla spp.
(Wiley, 2019)Clavigralla spp. (Hemiptera: Coreidae) are major pests of cowpea (Vigna unguiculata (L.) Walp, Fabacae), common bean (Phaseolus vulgaris L., Fabacae) and pigeon pea (Cajanus cajan L., Fabacae) in Africa. Clavigralla spp. ... -
A new genus and species of deep-water marine cirolanid isopod (Crustacea: Isopoda: Cirolanidae) from the Philippines
(LKCNHM, 2019)Sululana buta new genus, new species is described from deep water in the Sulu Sea, Philippines. The new genus shows weak affinities to Metacirolana Kussakin, 1979, and no clear affinities to other cirolanid genera. The ... -
An integrated insight into the response of bacterial communities to anthropogenic contaminants in a river: a case study of the Wonderfonteinspruit catchment area, South Africa
(PLoS, 2019)Bacterial communities in human-impacted rivers and streams are exposed to multiple anthropogenic contaminants, which can eventually lead to biodiversity loss and function. The Wonderfonteinspruit catchment area is impacted ... -
Agro-ecological options for fall armyworm (Spodoptera frugiperda JE Smith) management: providing low-cost, smallholder friendly solutions to an invasive pest
(Elsevier, 2019)Fall armyworm (FAW), a voracious agricultural pest native to North and South America, was first detected on the African continent in 2016 and has subsequently spread throughout the continent and across Asia. It has been ... -
Plant endemism in Griqualand West, South Africa
(Elsevier, 2019)Griqualand West, a region in the semi-arid Northern Cape and North-West provinces of South Africa, has been variously suggested to contain a number of range-restricted plant species, and was proposed to be a local centre ... -
New isopod and achelatan crustaceans from mid–Cretaceous reefal limestones in the Basque-Cantabrian Basin, northern Spain
(Elsevier, 2019)Mid-Cretaceous (upper Albian) strata of the Basque-Cantabrian Basin in northern Spain are renowned for their highly diverse crustacean assemblages from reef settings. From the Koskobilo quarry, two small, enrolled specimens ... -
Prediction of 24-hour sodium excretion from spot urine samples in South African adults: a comparison of four equations
(Nature, 2019)Repeated 24-hour urine collection is considered to be the gold standard for assessing salt intake. This is often impractical in large-population studies, especially in low–middle-income countries. Equations to estimate ... -
Time-to-onset of treatment for hypertension and hyperlipidaemia in South African diabetes mellitus patients: a survival analysis using medicine claims data
(Wiley, 2019)What is known and objective Hypertension and hyperlipidaemia have high prevalence among diabetics and increase patients’ risk of cardiovascular diseases, ultimately affecting prognosis negatively. Medicine claims data ... -
Coping facilitated troponin T increases and hypo-responsivity in the copeptin-HPA-axis during acute mental stress in a black cohort: the SABPA study
