The Heat is on: local government and climate governance in South Africa
(Cambridge University press, 2014)Departing from the fact that climate change poses localized effects, this article crit- ically considers from a legal perspective the role of local authorities in the South African government’s response ... -
Heat transfer phenomena in flow through packed beds
(North-West University, 2006)In order to simulate the thermal-fluid performance of a pebble bed reactor such as the PBMR, heat transfer phenomena in packed beds must be characterized. In the pseudo-heterogeneous simulation approach that is often ... -
Heat treatment of expressed breast milk as in-home procedure to limit mother-to-child transmission of HIV : a systematic review
(North-West University, 2009)Mother-to-child transmission (MTCT) of HIV is the most significant source of HIV infection in young children. As the HI virus has been identified in cell-free and cell-associated compartments of breast milk, it is clear ... -
A heatwave of accretion energy traced by masers in the G358-MM1 high-mass protostar
(Nature, 2020)High-mass stars are thought to accumulate much of their mass via short, infrequent bursts of disk-aided accretion1,2. Such accretion events are rare and difficult to observe directly but are known to drive enhanced maser ... -
Heavy drinking and interpersonal violence at and around different alcohol outlets in the North West Province, South Africa
(Stellenbosch University, 2013)South Africa has one of the highest per capita alcohol consumption levels in the world, with social norms dictating that when people drink, then consumption is heavy. On the other hand, South Africa also faces a globally ... -
Heavy metal concentration in soil in the tailing dam vicinity of an old gold mine in Johannesburg, South Africa†
(Agricultural Institute of Canada, 2016)Soil contamination with heavy metals is a serious concern to food production and human health. The present study was conducted to evaluate the impact of tailings from an old mining site on heavy metal contamination of soil. ... -
Heavy metal dissolution mechanisms from electrical industrial sludge
(Elsevier, 2019)In this paper, we investigate the release of heavy metals from sludge produced from an electrical industry using both organic and inorganic acids. Single and sequential extractions were conducted to assess heavy metals in ... -
Heavy metal pollution from gold mines: environmental effects and bacterial strategies for resistance
(MDPI, 2016)Mining activities can lead to the generation of large quantities of heavy metal laden wastes which are released in an uncontrolled manner, causing widespread contamination of the ecosystem. Though some heavy metals classified ... -
Heavy metal pollution in soil and plants from a mining area in the North West Province, South Africa
(North-West University (South Africa), 2019)South Africa is a mining country with a huge reserve of large deposits of gold, platinum, and coal, among others. However, contamination of soils and plants by heavy metals within the mining environment in South Africa has ... -
Heavy metal threats to plants and soil life in Southern Africa: present knowledge and consequences for ecological risk assessment
(Springer, 2019)In recent times there has been remarkable development in the field of soil ecotoxicology and risk assessment (RA) models. It is, however, debatable if these RA models are robust representatives for worldwide relevance. In ... -
Heavy metal tolerance potential of Aspergillus strains isolated from mining sites
(Taylor & Francis, 2016)Increased heavy metal pollution generated through anthropogenic activities into the environment has necessitated the need for eco-friendly remediation strategies such as mycoremediation. With a view to prospecting for fungi ... -
Heavy metal tolerance traits of filamentous fungi isolated from gold and gemstone mining sites
(Sociedade Brasileira de Microbiologia, 2018)tIncreased environmental pollution has necessitated the need for eco-friendly clean-upstrategies. Filamentous fungal species from gold and gemstone mine site soils were iso-lated, identified and assessed for their tolerance ... -
Heavy metal-induced oxidative stress on seed germination and seedling development: a critical review
(Springer, 2019)Heavy metal contamination in soils can influence plants and animals, often leading to toxicosis. Heavy metals can impact various biochemical processes in plants, including enzyme and antioxidant production, protein ... -
Heavy metal-induced oxidative stress on seed germination and seedling development: a critical review. Correction to. The original article can be found online at https://doi.org/10.1007/s10653-017-0005-8
(Springer, 2019)Unfortunately, in the original publication of the article, Prof. Yong Sik Ok’s affiliation was incorrectly published. The author’s affiliation is as follows. 1. Kangwon National University, Chuncheon 24341, Republic of ... -
Heavy metals in muscle tissue of healthy crocodiles from the Kruger National Park, South Africa
(Wiley, 2016)Mass mortality of Nile crocodile (Crocodylus niloticus) occurred in the Olifants River of the Kruger National Park (KNP) in 2008 from pansteatitis, a condition in which body fat becomes yellow and inflamed. Much research ... -
Heavy metals in seaweeds from a polluted estuary in coastal Maine
(New England Botanical Club, 2017)Seaweeds (macroalgae) accumulate heavy metals from seawater and can therefore serve as biological monitors of marine pollution. In this paper, we present data on the tissue chemistry of seaweeds from the area of Callahan ... -
Heavy metals in soils along unpaved roads in south west Cameroon: contamination levels and health risks
(Springer, 2016)Soils enriched with heavy metals from vehicular emission present a significant exposure route of heavy metals to individuals using unpaved roads. This study assessed the extent of Cd, Cr, Co, Cu, Ni, Pb and Zn contamination ... -
Heavy‐resistance exercise‐induced increases in jump performance are not explained by changes in neuromuscular function
(Wiley, 2017)Post‐activation potentiation (PAP) is the increased involuntary muscle twitch response to stimulation following strong contraction. The enhancement to whole‐body explosive muscular performance (PE) after heavy‐resistance ... -
