African horse sickness virus NS4 is a nucleocytoplasmic protein that localizes to PML nuclear bodies
(Microbiology Society, 2020)African horse sickness virus (AHSV) is the causative agent of the often fatal disease African horse sickness in equids. The non-structural protein NS4 is the only AHSV protein that localizes to the nucleus. Here we report ... -
Using stable δ13C and δ15N isotopes to assess foodweb structures in an African subtropical temporary pool
(Taylor & Francis, 2020)Southern Africa has one of the highest densities of temporary pools and some of the most understudied temporary wetlands in the world. Additionally, the eastern African annual killifishes (Nothobranchius spp.) are rare in ... -
Behavioural response as a reliable measure of acute nanomaterial toxicity in zebrafish larvae exposed to a carbon-based versus a metal-based nanomaterial
(Taylor & Francis, 2020)Production, use and disposal of products containing nanomaterials can lead to an increased presence of these particles in the environment and exposure to the organisms found there. It is therefore becoming increasingly ... -
Brominated flame retardants in wild bird eggs from the industrialised heartland of South Africa
(Taylor & Francis, 2020)Brominated flame-retardants (BFRs), including polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCD), were analysed in 77 eggs of 13 wild bird species from Gauteng and northern Free State (the industrial ... -
The effects of different gold mine tailings on growth, reproduction and avoidance-behaviour of earthworms
(Taylor & Francis, 2020)The mining industry plays a key role in the economic development of South Africa as one of the largest exporters of valuable resources, such as gold, platinum group metals and other metals and minerals. Unfortunately, ... -
The charismatic praying mantid: a gateway for insect conservation
(Taylor & Francis, 2020)Praying mantids (Mantodea) are not only apex predators with a ‘mystical’ status, but are also regarded as a kind of oracle and, in some cultures, as omens associated with good or bad. In the future, the cultural, mystical ... -
The North-West University (NWU) Zoology centennial special issue
(Taylor & Francis, 2020)This special issue of African Zoology celebrates 100 years of Zoology as a scientific discipline on the Potchefstroom Campus of the North-West University (NWU), previously known as the Potchefstroom University College ... -
Participatory mapping 2.0: new ways for children's participation in disaster risk reduction
(AIDR, 2020)In recent years, new forms of participatory mapping have emerged that foster the participation of children in disaster risk reduction. Participatory mapping enables children to produce insightful representations of their ... -
Comparison of the penetration, development and reproduction of Meloidogyne javanica and M. graminicola on partially resistant Oryza sativa cultivars from East Africa
(Brill, 2020)The host response to Meloidogyne javanica infection of selected Oryza sativa and NERICA (New Rice for Africa) genotypes that are commonly grown in Tanzania and East Africa was examined. The O. sativa genotypes ‘Komboka’ ... -
Application of the analytic hierarchy process to weight the criteria used to determine the Water Quality Index of groundwater in the northeastern basin of the Sidi Bouzid region, Central Tunisia
(Springer, 2020)The Sidi Bouzid and El Hjal Wadi basins together comprise one of the most important agricultural regions in Central Tunisia. Exploitation of the groundwater in this region is increasing exponentially. In this work, ... -
Projection bands and atoms in pervasive pre-Riesz spaces
(Springer, 2020)In vector lattices, the concept of a projection band is a basic tool. We deal with projection bands in the more general setting of an Archimedean pre-Riesz space X. We relate them to projection bands in a vector lattice ... -
Potential anti-TB investigational compounds and drugs with repurposing potential in TB therapy: a conspectus
(Springer, 2020)The latest WHO report estimates about 1.6 million global deaths annually from TB, which is further exacerbated by drug-resistant (DR) TB and comorbidities with diabetes and HIV. Exiguous dosing, incomplete treatment course, ... -
COVID-19: how do you self-isolate in a refugee camp?
(Springer, 2020)Over the last few months, we have seen how COVID-19 crossed administrative and national boundaries at the speed of fire—leaving nobody untouched. We believe that lessons learned from previous research investigating ... -
Metarhizium anisopliae and Beauveria bassiana: pathogenicity, horizontal transmission, and their effects on reproductive potential of Thaumatotibia leucotreta (Lepidoptera: Tortricidae)
(Oxford Univ Press, 2020)The polyphagous moth, Thaumatotibia leucotreta (Meyrick) is among the major constraints to the horticultural industry in East Africa. In a search of sustainable control methods, the pathogenicity of the dry conidia of 17 ... -
Novel anion exchange membrane based on poly(pentafluorostyrene) substituted with mercaptotetrazole pendant groups and its blend with polybenzimidazole for vanadium redox flow battery applications
(Elsevier, 2020)In order to evaluate the performance of the anion exchange membranes in a vanadium redox flow battery, a novel anion exchange polymer was synthesized via a three step process. Firstly, 1-(2-dimethylaminoethyl)-5-mercaptotetrazole ... -
Nematode assemblages and soil microbial communities in soils associated with glyphosate-resistant soybean
(Taylor & Francis, 2020)The introduction of genetically modified glyphosate-resistant (GR) crops led to increased use of glyphosate, with potential long-term effects on biological soil communities. Abundance and diversity of plant-parasitic and ... -
Enhancing social sustainability through the planning of third places: a theory-based framework
(Springer, 2020)With constantly changing societal needs, along with population growth and increasing urbanisation pressures, open public spaces are constantly competing against other land-uses to accommodate the increasing urban pressures. ... -
Overview of brain-to-gut axis exposed to chronic CNS bacterial infection(s) and a predictive urinary metabolic profile of a brain infected by mycobacterium tuberculosis
(Frontiers Media, 2020)A new paradigm in neuroscience has recently emerged – the brain–gut axis (BGA). The contemporary focus in this paradigm has been gut → brain (“bottom-up”), in which the gut-microbiome, and its perturbations, affects one’s ... -
“Frozen evolution” of an RNA virus suggests accidental release as a potential cause of arbovirus re-emergence
(Public Library of Science, 2020)The mechanisms underlying virus emergence are rarely well understood, making the appearance of outbreaks largely unpredictable. Bluetongue virus serotype 8 (BTV-8), an arthropod-borne virus of ruminants, emerged in livestock ... -
Determination of a safe distance for atomic hydrogen depositions in hot-wire chemical vapour deposition by means of CFD heat transfer simulations
(Tech Science Press, 2020)A heat transfer study was conducted, in the framework of Computational Fluid Dynamics (CFD), on a Hot-Wire Chemical Vapour Deposition (HWCVD) reactor chamber to determine a safe deposition distance for atomic hydrogen ...
