UFS medical students improve life for kids at Lethabo Daycare Centre

There is strong evidence to suggest that improving a caregiver’s knowledge has an impact on a child’s development. This is according to the Human Sciences Research Council. With this in mind, medical students from the University of the Free State (UFS) decided to work with a children’s daycare centre in order to improve the quality of care.

The students, from the School of Clinical Medicine in the Faculty of Health Sciences, were encouraged to assist NGOs in and around Bloemfontein, as part of their community service curriculum. They needed to look at hygiene, sanitation, cognitive development, physical development, vaccinations, prevention of diseases, nutritional status, socio-economic status, as well as the children’s environment. Moreover, they needed to highlight how a deficit from one factor could affect the other factors.
 
Through a meta-analysis study of 67 interventions regarding the above points, the students found most interventions to be generally effective in improving the children’s lives in one way or the other.
 
Selina Keta, the principal of Lethabo Daycare Centre in Mangaung, provided a list of problems she faced and ways in which the students could help to improve the conditions at the centre. She noted that the kitchen needed fixing because it did not meet the specifications required by the Department of Education for registration. The main issue was that the gas bottle for the stove was inside the kitchen and had to be moved out. The kitchen also needed steel counters, a sink, and running water. The students moved the gas bottle outside, and provided a fire extinguisher and first aid kit. They also provided a teacher at the centre with first-aid training from St John in Bloemfontein.

The students made sure there was running water and donated cupboards and microwaves to the centre. They also helped build two new classrooms, and there are plans for a third one to cater for different age groups.
As a final gift, the students painted the playground walls and arranged for the teachers to attend skills development workshops. They are also building a toy library for the centre.

Prof Tredoux turns theories regarding the formation of metals on its head
2013-09-17

The latest research conducted by Prof Marian Tredoux of the Department of Geology, in collaboration with her research assistant Bianca Kennedy and their colleagues in Germany, placed established theories regarding how minerals of the platinum-group of elements are formed, under close scrutiny.

The article on this research of which Prof Tredoux is a co-author – ‘Noble metal nanoclusters and nanoparticles precede mineral formation in magmatic sulphide melts’ – was published in Nature Communications on 6 September 2013. It is an online journal for research of the highest quality in the fields of biological, physical and chemical sciences.

This study found that atoms of platinum and arsenic create nanoclusters, long before the mineral sperrylite can crystallise. Thus, the platinum does not occur as a primary sulphur compound. The research was conducted at the Steinmann Institute of the University of Bonn, Germany, as well as here in Bloemfontein.

Monetary support from Inkaba yeAfrica – a German-South African multidisciplinary and intercultural Earth Science collaborative of the National Research Foundation (NRF) – made this research possible. Studies are now also being conducted on other metals in the precious metal group, specifically palladium, rhodium and ruthenium.

The discovery of the nanoclusters and the combination with arsenic can have far-reaching consequences for the platinum mine industry, if it can be utilised to recover a greater amount of platinum ore and therefore less wastage ending up in mine dumps. This will signify optimal mining of a scarce and valuable metal, one of South Africa’s most important export products.

For Prof Tredoux, the research results also prove thoughts she already had some twenty years ago around the forming of platinum minerals. “Researchers laughed in my face, but the evidence had to wait for the development of technology to prove it.” Young researchers were very excited at recent congresses about the findings, since the new models can bring new insights.

“Chemistry researchers have been talking about platinum element clusters in watery environments for quite a while, but it was thought that these would not appear in magmas (molten rock) due to the high temperatures (>1 000 degrees celsius).”

Prof Tredoux has already delivered lectures at congresses in Scotland, Hungary, Sweden and Italy on this research.
