Modelling of solar energetic particles by stochastic processes
(North-West University (South Africa), 2019)The focused transport of solar energetic particles has received increasingly more interest in the last couple of years due to upcoming missions to the Sun. Stochastic differential equations offer a numerically robust way ... -
Feeding and oviposition preference of Spodoptera frugiperda (Lepidoptera: Noctuidae) for selected poaceous plant species
(North-West University (South Africa), 2019)The Fall armyworm (FAW), Spodoptera frugiperda Smith (Lepidoptera: Noctuidae), is an agricultural pest native to the Americas. FAW is polyphagous with 274 larval host plant species being reported. Crop losses are caused ... -
Metabolomics and biochemical evaluation of skeletal muscle from Ndufs4 knockout mice
(North-West University (South Africa), 2019)The dysfunction of mitochondrial complex I (CI) impedes the most efficient mechanism feeding electrons into the respiratory chain (RC) — a system that, together with ATP synthase (CV), is responsible for the majority of ... -
The utilisation of hydro-geophysical methods for soil moisture measurements to optimise irrigation management
(North-West University (South Africa), 2019)Precision agriculture continuously seeks improved methods to enhance productivity whether it is for greater crop yields or economic viability regarding labour inputs and satisfying the demand in a shorter time span. Soil ... -
Identification of the response pathways of Escherichia coli and Enterococcus faecalis to glyphosate and it's major breakdown product Aminomethyl phosphonic acid (AMPA)
(North-West University (South Africa), 2019)Glyphosate is the active ingredient in non-selective herbicides, and disrupts the shikimate pathway of plants and bacteria by inhibiting the synthesis of aromatic amino acids. Application of glyphosate has increased ... -
Atmospheric SO₂ and NO₂ flux measurements at a savannah-grassland-agriculture landscape in South Africa
(North-West University (South Africa), 2019)Deposition measurements of SO2 and NO2 in South Africa are mainly limited to passive sampling where a constant deposition velocity is assumed for a specific land use category. Gaseous deposition velocities in South Africa ... -
Cancelable biometrics using hand geometry-based steganographic techniques
(North-West University (South Africa), 2019)Biometrics have long been used as an accepted user authentication method and have been implemented as a security measure in many real-world systems including personal computers, mobile devices, and physical access control. ... -
Modelling the spectral energy distribution and polarisation of blazars
(North-West University (South Africa), 2019)The optical emission from most blazars is dominated by the polarised synchrotron radiation of relativistic electrons in the jet. However, the thermal radiation from the accretion disc and host galaxy also contributes towards ... -
The improvement of Environmental Impact Assessment Report quality for Solar Photovoltaic projects in South Africa
(North-West University (South Africa), 2019)The quality of Environmental Impact Assessment Reports (EIARs) plays a critical role in a well-functioning Environmental Impact Assessment (EIA) system as EIARs are the key tool used by decision makers. Several studies ... -
Die elektroherwinning van Fe en H2SO4 uit ’n FeSO4-logingsoplossing met behulp van anioonruilmembrane
(North-West University (South Africa), 2019)The purpose of this study was to develop an economical, safe and environmentally friendly electrochemical process for the conversion and recovery of Fe and H2SO4 from a FeSO4 leaching solution. For this purpose, two basic ... -
Determination of coal mine impacts on surface water bodies (Olifants River)
(North-West University (South Africa), 2019)The purpose of the study was to determine the impact of a coal mine on the water quality quaternary catchment B11J. The study area is situated in quaternary catchment B11J of the Olifants Water Management Area. The objectives ... -
Comparative molecular and morphological identification, and reproduction potential of South African Meloidogyne species with emphasis on Meloidogyne enterolobii
(North-West University (South Africa), 2019)Meloidogyne is a destructive nematode genus parasitising crops worldwide. Meloidogyne arenaria, M. hapla, M. incognita and M. javanica are listed as the economically most important species, but M. enterolobii is considered ... -
The quality of Integrated Waste Management Plans for Metropolitan Municipalities in South Africa
(North-West University (South Africa), 2019)Waste management is a concern in both developed and developing countries. Rapid growth in industrialization and urbanization is resulting in the increase of waste generation and volumes in metropolitian cities. Poor waste ... -
Waste dumping in Sharpeville (Emfuleni Municipality) : an investigation of the characteristics and the potential impacts on air quality
(North-West University (South Africa), 2019)Waste management is of significance as poorly handled waste can have detrimental effects on both the environment, and the public health. Open burning of domestic waste is a common practice in developing countries, particularly ... -
Physico-chemical and microbiological data of the Mooi River : a historical perspective
(North-West University (South Africa), 2019)Increased urbanisation and anthropogenic disturbances have caused water quality of many freshwater systems to deteriorate over the years in South Africa. This is due to domestic, industrial, and agricultural waste being ... -
Characteristics of antibiotic resistant bacteria in raw and drinking water from water production facilities
(North-West University (South Africa), 2019)Water is a limited resource, and the quality of raw water has an impact on drinking water production. Regular testing is done to ensure that the quality is compliant with regulations. Heterotrophic bacteria are widely used ... -
Assessment of nitrate pollution in groundwater (Chaneng Village, Rustenburg)
(North-West University (South Africa), 2019)Groundwater plays a vital role in the water provision for the areas that are so remote in such a way that rendering municipal services (piped water) proves to be cumbersome. While deemed so essential, it is also prone to ... -
Brush packing as a restoration technology to restore grazing capacity after bush control in the North West Province
(North-West University (South Africa), 2019)The Savanna Biome covers approximately 35% of South Africa’s land area and is considered a precious resource which forms the foundation for livestock production and wildlife-related industries. Evidence accumulated in the ... -
The influence of neutralisation time lag on plant-available phosphorous in acid mine tailings
(North-West University (South Africa), 2019)The main goal of vegetation establishment on tailings storage facilities is to stabilise their slopes to improve the retention and infiltration of water, thereby reducing the effects of wind and water erosion. The ... -
