In South Africa鈥檚 pluralistic healthcare system, medicinal plants are an integral part of healing and treating an array of diseases. This is also the case in rural areas of South Africa, where healthcare facilities are hard to access. There is a lack of literature on the use of medicinal plants to cure ailments common to children, and this paper fills this gap. A total of 18 participants were interviewed using semi-structured interviews. A purposive approach was used to sample the study cohorts. A total of 28 medicinal plants representing 19 different families were recorded, with the family Asteraceae (11%) having the most medicinal plants. The remaining plants (82%) were distributed equally among the following families: Rubiaceae, Canellaceae, Aloaceae, Rutaceae, Thymeleaceae, Myrinaceae, Olinaceae, Iradeceae, Zingiberaceae, Capparaceae, Aizoaceae, Fabaceae, Geraniaceae, Cornaceae, Monimiaceae, Talinaceae, Chrysobalanaceae, and Icacinaceae. Oral administration was the most common mode of administration, with 82% of plants taken orally. Healing was proven to be holistic; it was more than just treating physical ailments as such; infants were protected from evil spirits that made them vulnerable to illnesses. There was also evidence of the assimilation of Dutch medicine and animal products into traditional healing methods. In order to mitigate the prevalence of disease and illness in South Africa, I recommend that diversity in healing practices should be acknowledged and appreciated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=infants" title="infants">infants</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional%20healers" title=" traditional healers"> traditional healers</a>, <a href="https://publications.waset.org/abstracts/search?q=primary%20care%20givers" title=" primary care givers"> primary care givers</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional%20medicine" title=" traditional medicine"> traditional medicine</a> </p> <a href="https://publications.waset.org/abstracts/175398/an-ethnobotanical-survey-of-medicinal-plants-for-the-treatment-of-infantile-diarrhea-in-the-eastern-cape-province-of-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175398.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">83</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Simultaneous Removal of Arsenic and Toxic Metals from Contaminated Soil: a Pilot-Scale Demonstration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20Francisco%20Morales%20Arteaga">Juan Francisco Morales Arteaga</a>, <a href="https://publications.waset.org/abstracts/search?q=Simon%20Gluhar"> Simon Gluhar</a>, <a href="https://publications.waset.org/abstracts/search?q=Anela%20Kaurin"> Anela Kaurin</a>, <a href="https://publications.waset.org/abstracts/search?q=Domen%20Lestan"> Domen Lestan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Contaminated soils are recognized as one of the most pressing global environmental problems. As is one of the most hazardous elements: chronic exposure to arsenic has devastating effects on health, cardiovascular diseases, cancer, and eventually death. Pb, Zn and Cd are very highly toxic metals that affect almost every organ in the body. With this in mind, new technologies for soil remediation processes are urgently needed. Calcareous artificially contaminated soil containing 231 mg kg-1 As and historically contaminated with Pb, Zn and Cd was washed with a 1:1.5 solid-liquid ratio of 90 mM EDTA, 100 mM oxalic acid, and 50 mM sodium dithionite to remove 59, 75, 29, and 53% of As, Pb, Zn, and Cd, respectively. To reduce emissions of residual EDTA and chelated metals from the remediated soil, zero valent iron (ZVI) was added (1% w/w) to the slurry of the washed soil immediately prior to rinsing. Experimental controls were conducted without the addition of ZVI after remediation. The use of ZVI reduced metal leachability and minimized toxic emissions 21 days after remediation. After this time, NH4NO3 extraction was performed to determine the mobility of toxic elements in the soil. In addition, Unified Human BioaccessibilityMethod (UBM) was performed to quantify the bioaccessibility levels of metals in stimulated human gastric and gastrointestinal phases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soil%20remediation" title="soil remediation">soil remediation</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20science" title=" soil science"> soil science</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20washing" title=" soil washing"> soil washing</a>, <a href="https://publications.waset.org/abstracts/search?q=toxic%20metals%20removal" title=" toxic metals removal"> toxic metals removal</a> </p> <a href="https://publications.waset.org/abstracts/142910/simultaneous-removal-of-arsenic-and-toxic-metals-from-contaminated-soil-a-pilot-scale-demonstration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142910.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">175</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Numerical Simulation of Two-Phase Flows Using a Pressure-Based Solver</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lei%20Zhang">Lei Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Michel%20Ghidaglia"> Jean-Michel Ghidaglia</a>, <a href="https://publications.waset.org/abstracts/search?q=Anela%20Kumbaro"> Anela Kumbaro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work focuses on numerical simulation of two-phase flows based on the bi-fluid six-equation model widely used in many industrial areas, such as nuclear power plant safety analysis. A pressure-based numerical method is adopted in our studies due to the fact that in two-phase flows, it is common to have a large range of Mach numbers because of the mixture of liquid and gas, and density-based solvers experience stiffness problems as well as a loss of accuracy when approaching the low Mach number limit. This work extends the semi-implicit pressure solver in the nuclear component CUPID code, where the governing equations are solved on unstructured grids with co-located variables to accommodate complicated geometries. A conservative version of the solver is developed in order to capture exactly the shock in one-phase flows, and is extended to two-phase situations. An inter-facial pressure term is added to the bi-fluid model to make the system hyperbolic and to establish a well-posed mathematical problem that will allow us to obtain convergent solutions with refined meshes. The ability of the numerical method to treat phase appearance and disappearance as well as the behavior of the scheme at low Mach numbers will be demonstrated through several numerical results. Finally, inter-facial mass and heat transfer models are included to deal with situations when mass and energy transfer between phases is important, and associated industrial numerical benchmarks with tabulated EOS (equations of state) for fluids are performed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=two-phase%20flows"
