Even well-studied groups of alien species might be poorly inventoried : Australian Acacia species in South Africa as a case study
(Pensoft Publishers, 2018)Understanding the status and extent of spread of alien plants is crucial for effective management. We explore this issue using Australian Acacia species (wattles) in South Africa (a global hotspot for wattle introductions ... -
Global environmental and socio-economic impacts of selected alien grasses as a basis for ranking threats to South Africa
(Pensoft Publishers, 2018)Decisions to allocate management resources should be underpinned by estimates of the impacts of biological invasions that are comparable across species and locations. For the same reason, it is important to assess what ... -
Patterns and traits associated with invasions by predatory marine crabs
(Pensoft Publishers, 2018)Predatory crabs are considered amongst the most successful marine invasive groups. Nonetheless, most studies of these taxa have been descriptive in nature, biased towards specific species or regions and have seldom considered ... -
The relevance of using various scoring schemes revealed by an impact assessment of feral mammals
(Pensoft Publishers, 2018)Impact scoring schemes are useful for identifying to what extent alien species cause damage. Quantifying the similarity and differences between impact scoring schemes can help determine how to optimally use these tools for ... -
Supplementing the lack of ubuntu? The ministry of Zimbabwe’s Mashoko Christian Hospital to people living with HIV and AIDS in challenging their stigmatisation in the church
(AOSIS, 2019)This article uses the African communal concept of ubuntu to reflect on the ministry of Mashoko Christian Hospital (MCH), Zimbabwe, to people living with the human immunodeficiency virus (HIV) and AIDS (PLWHA) during the ... -
Diffusion markers of dendritic density and arborization in gray matter predict differences in intelligence
(Nature Research (part of Springer Nature), 2018)Previous research has demonstrated that individuals with higher intelligence are more likely to have larger gray matter volume in brain areas predominantly located in parieto-frontal regions. These findings were usually ... -
Similarity of introduced plant species to native ones facilitates naturalization, but differences enhance invasion success
(Nature Research (part of Springer Nature), 2018)The search for traits associated with plant invasiveness has yielded contradictory results, in part because most previous studies have failed to recognize that different traits are important at different stages along the ... -
The structure and function of the global citrus rhizosphere microbiome
(Nature Research (part of Springer Nature), 2018)Citrus is a globally important, perennial fruit crop whose rhizosphere microbiome is thought to play an important role in promoting citrus growth and health. Here, we report a comprehensive analysis of the structural and ... -
Nutrients composition in fit snacks made from ostrich, beef and chicken dried meat
(MDPI, 2018)The aim of the study was to compare three types of meat snacks made from ostrich, beef, and chicken meat in relation to their nutrients content including fat, fatty acids, heme iron, and peptides, like anserine and carnosine, ... -
Health expenditure, child and maternal mortality nexus : a comparative global analysis
(BioMed Central, 2018-07)Background: This paper provides empirical evidence on how the relationship between health expenditure and health outcomes varies across countries at different income levels. Method: Heterogeneity and cross-section ... -
Standard method for microCT-based additive manufacturing quality control 4 : Metal powder analysis
(Elsevier, 2018)X-ray micro computed tomography (microCT) can be applied to analyse powder feedstock used in additive manufacturing. In this paper, we demonstrate a dedicated workflow for this analysis method, specifically for Ti6Al4V ... -
Standard method for microCT-based additive manufacturing quality control 3 : surface roughness
(Elsevier, 2018)The use of microCT of 10 mm coupon samples produced by AM has the potential to provide useful information of mean density and detailed porosity information of the interior of the samples. In addition, the same scan data ... -
Standard method for microCT-based additive manufacturing quality control 2 : density measurement
(Elsevier, 2018)MicroCT is best known for its ability to detect and quantify porosity or defects, and to visualize its 3D distribution. However, it is also possible to obtain accurate volumetric measurements from parts – this can be used ... -
Standard method for microCT-based additive manufacturing quality control 1 : porosity analysis
