Nonparametric estimation of the antimode and the minimum of a density function
(Potchefstroom University for Christian Higher Education, 1995, 1995)The study of the estimation of the antimode and the minimum of a density function has been neglected in the li terature, in spite of their useful applications. The main objective of this thesis is to propose and study ... -
Plasma phospholipid fatty acid patterns are associated with adiposity and the metabolic syndrome in black South Africans: a cross-sectional study
(Clinics Cardive Publishing, 2019)Background: Diets rich in n-6 polyunsaturated fatty acids (PUFAs) and saturated fatty acids (SFA) have been associated with increased risk of obesity and the metabolic syndrome (MetS), but the evidence is inconsistent, ... -
Crop rotation sequencing to minimize yield losses of summer-irrigated lowland rice in Myanmar caused by the rice root-knot nematode Meloidogyne graminicola
(Taylor & Francis, 2020)The effect of different rice-based crop rotation sequences on the population densities of Meloidogyne graminicola and on the yield of rice was evaluated in a microplot experiment under lowland rice field conditions. Ten ... -
One savanna, many shapes: how bush control affects the woody layer in the southern Kalahari
(Elsevier, 2019)Bush thickening (shrub encroachment) is a major ecological and economic threat in southern African savannas. Different types and intensities of bush control (BC) are applied to counteract and mitigate bush thickening. ... -
How toxic is a non-toxic nanomaterial: behaviour as an indicator of effect in Danio rerio exposed to nanogold
(Elsevier, 2019)Gold nanoparticles are used as drug delivery vectors based on the assumption that they have low toxicity. Literature has, however, produced conflicting results over the last few years. As such, this study aimed to investigate ... -
A critical systems thinking approach to empower refugees based on Maslow's theory of human motivation
(Wiley, 2019)The life of a refugee is hard. We show how Maslow's theory of motivation can be utilized to better understand the situation of refugees in the Netherlands. Our aim is to formulate guidelines for the authorities in terms ... -
Embracing evolutionary change to advance impact assessment (IA)
(Taylor & Francis, 2019)Impact assessment (IA) originated as, and continues to be, an instrument that contributes towards sustainable development. In response to the considerable sustainability challenges facing our planet this article argues for ... -
Using detergent-enhanced LAMP for African trypanosome detection in human cerebrospinal fluid and implications for disease staging
(PLoS, 2019)Objective Where human African trypanosomiasis (HAT) patients are seen, failure to microscopically diagnose infections by Trypanosoma brucei gambiense in blood smears and/or cerebrospinal fluid (CSF) in the critical early ... -
Effects of the organochlorine p,p’-DDT on MCF-7 cells: investigating metabolic and immune modulatory transcriptomic changes
(Elsevier, 2019)The organochlorine pesticide dichloro-diphenyl-trichloroethane (DDT) is persistent in the environment and leadsto adverse human health effects. High levels in breast milk pose a threat to both breast tissue and nursing ... -
Tissue distribution and characterization of feline cytochrome P450 genes related to polychlorinated biphenyl exposure
(Elsevier, 2019)Cats have been known to be extremely sensitive to chemical exposures. To understand these model species' sensitivity to chemicals and their toxicities, the expression profiles of xenobiotic-metabolizing enzymes should be ... -
Metal concentrations in corals from South Africa and the Mascarene Basin: a first assessment for the Western Indian Ocean
(Elsevier, 2019)Little knowledge exists on the state of metal contamination in corals from the Western Indian Ocean (WIO). Fragments of four soft and five hard coral genera were collected from five sites in the WIO– Sodwana Bay and Aliwal ... -
Gold nanostar colorimetric detection of fructosyl valine as a potential future point of care biosensor candidate for glycated haemoglobin detection
(MDPI, 2019)Diabetes Mellitus is a growing global concern. The current methods used to detect glycated haemoglobin are precise, however, utilise expensive equipment, reagents and consumables. These are luxuries which rural communities ... -
In-vitro cytotoxicity of various Siphonochilus aethiopicus (Schweinf.) B.L. Burtt extracts in combination with selected tableting excipients
(Wiley, 2019)Objectives To investigate the cytotoxic potential of S. aethiopicus extracts in combination with chitosan and Pharmacel 101, on two cell lines. Methods Extracts were chemically characterised utilising UPLC-Q-TOF/MS, ... -
The disconnect between individual-level and population-level HIV prevention benefits of antiretroviral treatment
(Elsevier, 2019)In 2019, the HIV pandemic is growing and soon over 40 million people will be living with HIV. Effective population-based approaches to decrease HIV incidence are as relevant as ever given modest reductions observed over ... -
Particle size and metal composition of gouging and lancing fumes
(Taylor & Francis, 2019)Metal gouging and lancing liberate particles of an unknown size and composition. Fumes are formed when vaporized materials condense in air, creating fine and ultrafine particles which can agglomerate. Particle sizes may ...
