Eleazar - the honor of death: Eleazar's death within the perspective of honor and shame
(University of Johannesburg, 2011)Martyrdom has become 'n focal point in recent decades. Although many aspects of martyrdom have been studied, the aspect of honor and shame is yet to be fully explored. This article aims to take a fresh look at martyrdom, ... -
Electrical and cardiac stress reactivity associations with pre-clinical target organ damage : the SABPA study
(North-West University (South Africa) , Potchefstroom Campus, 2016)Motivation: People’s physiological adaptive responses to chronic stressful environments have been persistently associated with an increased incidence of cardiovascular diseases (CVD) and co-morbidities. An inability to ... -
Electrical circuit modelling of double layer capacitors for power electronics and energy storage applications: a review
(MDPI, 2018)There has been increasing interests in the use of double layer capacitors (DLCs)—most commonly referred to as supercapacitors (SCs), ultra-capacitors (UCs), or hybrid capacitors (HCs)—in the field of power electronics. ... -
Electrical resistivity of carbonaceous bed material at high temperature
(Springer Verlag, 2020)This study reports the effect of high-temperature treatment on the electrical properties of charcoal, coal, and coke. The electrical resistivity of industrial charcoal samples used as a reducing agent in electric arc ... -
Electricity adequacy in South Africa
(North-West University (South Africa), 2018)The motivation to conduct this study arises from the current uncertainty of electricity security in South Africa (SA). Between the last quarter of 2007 and the first quarter of 2008, South Africa experienced the harshest ... -
Electricity cost optimisation of a surface potable water pump system
(North-West University, 2007)South Africa is fast approaching an era where its electrical energy demand will surpass the generating capacity of it's primary utility. The reason for this is due to the fact that over the past 10 years, the economic ... -
Electricity price hikes : managing for sustainable value creation in a mining company
(North-West University, 2012)Companies are faced with challenges constraining the achievement of set budgets, goals, profit and cost of product, to name a few, on a daily basis. These challenges influence value creation and sustainable value creation. ... -
Electricity tarrif structure and revenue collection in South Africa : a case study of the greater Mafikeng area
(North-West University (South Africa), 2010)Until 2004, successive governments in the post apartheid South Africa were reluctant to approve economic rates or tariff increases to enable Eskom to achieve the statutory financial performance standard. However, in ... -
Electrocatalytic activity of sputtered Pt and Pt3Pd2 thin films for SO2(aq) electro-oxidation
(North-West University, 2018)The ever growing demand for energy and worldwide focus on global warming have dictated the course of research in energy production for the past couple of decades, with much emphasis placed on the need for clean and renewable ... -
Electrocatalytic oxidation of Epinephrine and Norepinephrine at metal oxide doped phthalocyanine/MWCNT composite sensor
(Nature Publishing Group, 2016)Glassy carbon electrode (GCE) was modified with metal oxides (MO?=?Fe3O4, ZnO) nanoparticles doped phthalocyanine (Pc) and functionalized MWCNTs, and the electrocatalytic properties were studied. Successful synthesis of ... -
Electrocatalytic process for ammonia electrolysis: a remediation technique with hydrogen co-generation
(ESG, 2016)Alkaline ammonia electrocatalysis offers a favorable technique for hydrogen generation and simultaneous conservation of environmental sustainability. In this work, the electrooxidation of ammonia on platinum-Iridium (Pt-Ir) ... -
Electrochemical and computational studies of benzothiophene compounds as corrosion inhibitors of mild steel in 1 M hydrochloric acid
(North-West University (South Africa), 2022)In the study, five benzothiophene derivatives were used as corrosion inhibitors for mild steel in a 1 M hydrochloric acid solution. The molecules have the same benzothiophene ring and only differ in the substituents attached ... -
An electrochemical and theoretical comparison of ionic transport through a polystyrene based titanium-vanadium (1:2) phosphate membrane
(Elsevier, 2011)Ionic potentials were measured across polystyrene based titanium–vanadium (1:2) phosphate membranes with 1:1 electrolytes at different concentrations. These observed values are found to compare well with membrane potentials ... -
