Anodic destruction of abamectin acaricide solution by BDD–anodic oxidation
(ESG, 2014)This paper presents the study of the electrochemical oxidation of the pesticide Abamectin at a boron-doped diamond (BDD). The effect of using different supporting electrolytes (NaCl, K₂SO₄, Na₂CO₃ and Na₂SO₄) ... -
Assessing ecosystem services in the Fafung community of the North West Province, South Africa
(North-West University (South Africa), 2021)Fafung is a deep rural community in South Africa’s North West Province that borders on the Borakalalo Nature Reserve. As with many communities of its kind, Fafung faces several needs and challenges such as unemployment, ... -
Best land-use strategies towards sustainable biodiversity and land degradation management in semi-arid western rangelands in southern Africa, with special reference to ants as bio-indicators
(North-West University, 2006)In South Africa, the unsustainable use of natural resources by domestic livestock has led to resource depletion and serious land degradation. Rangeland degradation, especially bush encroachment and soil erosion, is ... -
Condition monitoring thermal properties of a 20A hydraulic-magnetic MCB
(NWU, 2018)Heat is one of the major causes of degradation which can cause a reduction in performance, reliability and life span of miniature circuit breakers (MCBs) [1]. In order to diagnose the condition of electrical equipment, ... -
An ecological study of the plant communities and degraded areas of the Highveld National Park, North West Province, South Africa
(North-West University, 2007)The objectives of the study were to identify, classify, describe and map the plant communities in the proposed Highveld National Park, including the degraded Spitskop areas. Vegetation sampling was done by means of the ... -
EcoRestore : a decision support system for the restoration of degraded rangelands in southern Africa
(North-West University, 2003)Land degradation is a process that causes the reduction in resource potential of natural rangelands and occurs widespread throughout southern Africa. This process is mainly characterized by the loss in vegetation cover, ... -
The effect of α-irradiation from enriched uranium on the leaching properties of PTFE
(Elsevier, 2017)In the uranium enrichment plants of the South African Nuclear Energy Corporation SOC Ltd (Necsa), sintered polytetrafluoroethylene (PTFE) filters were used to remove gas entrained solid particles, in order to prevent ... -
The evaluation of different technologies to restore old cultivated lands
(North-West University, 2008)As production costs for the cultivation of cash crops increased and government subsidies for farmers decreased and eventually stopped, the farmers stopped to cultivate the marginal to lower potential soils. The higher input ... -
The influence of bedding-plane orientation on the degradation characteristics of a South African Waterberg coal
(Taylor & Francis, 2016)A tomographic study of coal microstructure (coal bedding planes, pre-existing cracks, microlithotype boundaries, and mineral boundaries) was undertaken to explain its influence on coal degradation due to impact. A number ... -
A tomographic exploration of the internal structure of coal and its role in single particle breakage
(North-West University (South Africa) , Potchefstroom Campus, 2016)The unintentional production of coal fines, or coal degradation, during coal beneficiation can lead to significant financial losses for coal producers. Coal fines in a closely sized feed can also lead to channelling, ...
