A 4-day test weighing study to assess volume and variations in fat and energy content of breast milk
(North-West University (South Africa) , Potchefstroom Campus, 2016)Background: Exclusive breastfeeding is recommended for the first six months of life. Breast milk intake and composition not only vary between populations and individuals, but also within feeds, within days and between ... -
The advanced and moderate-growth development paths for the viability and future growth of small wind energy systems
(Elsevier, 2020)The government of South Africa initiated the Integrated Resource Plan (IRP) 2010–2030 to redefine the country's energy portfolio and commitment to wind energy development. The document recommended more research in small ... -
Application of Sm0.8Sr0.2Fe1-xCoxO3-δ (x = 0.2, 0.5, 0.8) perovskite for the oxygen evolution reaction in alkaline media
(Springer, 2019)A new type of perovskite, i.e. Sm0.8Sr0.2Fe0.8Co0.2O3-δ (SSFC1), Sm0.8Sr0.2Fe0.5Co0.5O3-δ (SSFC2), and Sm0.8Sr0.2Fe0.2Co0.8O3-δ (SSFC3) were (i) synthesised by employing a sol gel method with subsequent calcination at 1000 ... -
Compressed air energy savings on an iron production plant
(North-West University (South Africa) , Potchefstroom Campus, 2016)In the past several decades, energy efficiency has become increasingly important. A large driver behind this is reducing greenhouse gases that are caused by the combustion of fossil fuels. Most electricity generated in ... -
CRSN Energy-Efficient Mechanism Based on Dynamic Spectrum Access and Asynchronous Sleep-Wake Scheduling
(North-West University (South Africa), 2020)Cognitive Radio Sensor Network (CRSN) is considered as a viable wireless networking paradigm solution to address the issues of spectrum underutilization and uncontrollable interferences in Wireless Sensor Network (WSN) due ... -
Current status, hurdles and future prospects of biogas digestion technology in Africa
(Elsevier, 2017)Anaerobic digestion of organic wastes results in the production of biogas and a nutrient-rich digestate. The biogas that is produced through this process consists of methane, carbon dioxide and minute amounts of other ... -
Developing a by-product gas controller to improve on-site electricity generation for iron and steel manufacturing
(North-West University, 2018)High production costs and low demands have placed the South African iron and steel manufacturing industry under severe pressure. The steel manufacturing industry is therefore forced to streamline internal structures and ... -
A development path for small wind energy systems in South Africa
(North-West University (South Africa) , Potchefstroom Campus, 2017)South Africa‟s electricity generation is primarily through coal, and this contributes significantly to the country‟s high carbon emissions. In 2010, the Department of Energy, initiated the Integrated Resource Plan (IRP) ... -
Energy and economic performance of small wind energy systems under different climatic conditions of South Africa
(Elsevier, 2018)Several studies have established the abundance of the wind resources in South Africa, which can position the country as a leader in wind power generation continentally if the resource is well harnessed. In acknowledging ... -
Energy and exergy analyses of a subcritical pulverised coal-fired boiler based on the effects of slagging and fouling
(Elsevier, 2017)Globally coal-fired power plants are still predominantly utilised for production of electrical energy. The efficiency of a coal-fired power plant is greatly influenced by the performance of the boiler. In turn, the boiler ...
