- ItemA research agenda for colostrum supplement manufacturing: insights from a scoping review(African Journal of Biological Sciences, 2024-06) Mutirori, Tinashe M.; Roopa, Meelan; Grobbelaar, Sara S.ABSTRACT: Bovine Colostrum (BC) is the first milk cows produce after giving birth. BC contains essential nutrients required by neonates. These nutrients may be potentially beneficial to humans. This review aims to establish the nature of the published evidence, thereby detailing the use of bovine colostrum in supplement manufacturing. This scoping review focuses on evidence in the literature related to the manufacturing process, efficacy or efficiency, and nutritional composition of bovine colostrum supplements. The Scopus database was searched to identify all relevant full-text literature published in English. The methodology used to conduct this scoping review is the JBI method. The scoping review follows the Preferred Reporting Items for Systematic Reviews and Meta-analysis extension for Scoping Reviews (PRISMA-Scr) reporting method. Bibliometric analyses were conducted on the included publications. An R-based software package called bibliometrix was used to perform the Bibliometric analyses. The findings from the studies revealed that there has been an increase in annual scientific production on the topic, highlighting an increase in interest in the subject. The thematic map generated using bibliometrix software using the author’s keywords revealed that some of the keywords were in the motor themes quadrant, indicating higher relevance and coherence of the research topics. The review's findings also revealed high research output from developed countries and low research output from developing countries. The results indicate thatEgypt produced the highest research output in the selected publications on the African continent, with four documents on the topic. The research fields that made the largest contribution to the topic under review were medicine, agriculture, and nursing, with 29.4%, 21.2%, and 18.2% contributions, respectively. The results indicate that the countries with the highest frequency of collaboration in the selected literature are the US, the UK, and Australia. Insights from the scoping review were used to develop a Research Agenda to address the research gaps within the research area. Quality Standards, Market Trends, Research Contributions, Nutritional Benefits, Feasibility Studies, and Business Models were the areas proposed for further research to address knowledge gaps in the Bovine Colostrum research field.
- ItemMobiele toerusting wat die suksesvolle vervoer van intermodale standaardhouers per spoor ondersteun(Suid-Afrikaanse Akademie vir Wetenskap en Kuns, 2021) Pienaar, Wessel J.Hierdie artikel bied ’n oorsig van die tegniese en funksionele eienskappe van mobiele toerusting wat die suksesvolle vervoer van intermodale standaardhouers per spoor ondersteun. Die toerusting ter sprake is goederetreine, houerspoortrokke, intermodale standaardhouers en mobiele houerhanteringstoerusting. Goederetreine word verdeel in trokvragtreine en eenheidstreine, en die gepastheid van elke treinsoort vir die grootskaalse vervoer van intermodale standaardhouers word aangetoon. Daarna word die twee soorte doelgeboude houerspoortrokke toegelig. Die tien soorte intermodale standaardhouers wat beskikbaar is om goedere in te vervoer, word vervolgens behandel. Ten slotte word die funksies en eienskappe bespreek van hedendaagse mobiele hanteringstoerusting wat doeltreffend aan die houerhanteringsvereistes van moderne intermodale vervoerbedrywighede voldoen.
- ItemA performance measurement system for integrated production and maintenance planning(Elsevier, 2020) Schreiber, M.; Schutte, C. S. L.; Braunreuther, S.; Reinhart, G.The increasing amount of production resources to be maintained and efficiency requirements are forcing manufacturing companies to improve production and maintenance effectiveness by a mutual consideration of both functions in an integrated planning process. However, less attention is paid to monitor the performance of manufacturing systems based on key performance indicators to identify the need for measures and adapting plans. Performance Measurement Systems (PMS) are applied to accomplish this task. Therefore, this paper presents an evaluation of existing PMS’s for production and maintenance planning. A new PMS that considers strategic and operational views is presented and validated by an industrial case study.
- ItemA network maturity mapping tool for demand-driven supply chain management : a case for the public healthcare sector(MDPI, 2021-10-29) Bvuchete, Munyaradzi; Grobbelaar, Sara Saartjie; Van Eeden, JoubertThe healthcare supply chain is a complex adaptive ecosystem that facilitates the delivery of health products to the end patient in a cost-effective way. However, low forecast accuracy and high demand volatility in healthcare supply chains have resulted in an increase in stockouts, operational inefficiencies, poor health outcomes, and a significant increase in supply chain costs. To cope with these challenges, organisations are trying to adopt demand-driven supply chain management (DDSCM) operating practices which have been established in other sectors such as the telecommunications, fruit, and flower industries. However, previous studies have not considered these practices in the healthcare industry, and hence no methodologies exist that support the implementation of these practices in this context. Moreover, current studies present cases where the focus has been on improving and expanding individual organisational performance, but no supply chain network-level studies exist on the healthcare industry. Therefore, this paper provides a network-level analysis when addressing DDSCM in the healthcare industry. A grounded theory-based approach coupled with a conceptual framework analysis process was used to leverage a systematized literature review methodology with the development of a network maturity mapping tool for DDSCM which was validated in the public healthcare sector.
- ItemEvaluating the energy potential of solar PV located on mining properties in the Northern Cape Province of South Africa(MDPI, 2020-07-21) Van der Merwe, Waldo; Brent, Alan C.ENGLISH ABSTRACT: The lauded Renewable Energy Independent Power Producer Procurement Program (REIPPPP) has achieved much in stimulating private sector investment in the renewable energy market in South Africa. Yet, 95% of electricity generated is still from a single source, the state-owned utility Eskom. This paper set out to explore the policy sphere governing electricity generation and identifying possible avenues that can contribute to a more vibrant solar energy market in the most solar abundant province of South Africa, the Northern Cape Province. Licensed mines were identified as low hanging fruit due to a large policy overlap and leeway within existing mining policy. A solar audit of these areas was performed, based on accepted multi-criteria decision analysis techniques, and found that a potential 369 TWh to 679 TWh per annum can be generated, exceeding South Africa’s current electricity usage.
