Qwaqwa Campus vaccination drive

As the University of the Free State is encouraging staff and students to be vaccinated in order for all of us to return to campus life as we know it, the Qwaqwa Campus held its first in-person vaccination activation drive for its first and returning students. The drive was to further encourage students to vaccinate, and to keep themselves and others safe by educating themselves.

The cheerful and excited crowd of more than 100 students were gathered at the Amphitheatre on campus, where they got to know more about the COVID-19 Regulations and Required Vaccination Policy and interacted with Department of Health officials to understand more about the jabs and booster shots.

No one is forced, but everyone is encouraged

The university’s approved policy came into effect on 14 February, requiring staff and students to be vaccinated as a measure towards ensuring everyone’s smooth return to its three campuses. However, as Qwaqwa Campus Principal Dr Martin Mandew highlighted, “no one is being forced to vaccinate, but we are all strongly encouraged to do so”.

Dr Mandew said the student experience is too rich and vibrant to be confined to virtual learning. He showed students his own vaccination certificate, quoting a Zulu proverb, ‘indlela ibuzwa kwabaphambili’, which loosely translated means ‘those who have gone before you can show the way’.

“If you are not vaccinated, it will be impossible for us to enjoy face-to-face interaction again. Ask yourself: ‘If the principal is vaccinated, who am I not to be?” he said.

The lively drive also kept students entertained through live performances by local artists. 

Students could also raise pressing issues and questions with Department of Health officials – including common side effects, apathy against vaccination due to religious beliefs, the efficacy of the vaccine to protect against COVID-19, and the implementation of the UFS Vaccination Policy. 

The programme line-up also included messages of support from the Director: Student Affairs, Zoleka Dotwana, the Deputy Director of Housing and Residences, Zakhele Mdluli, and UVPERSU Vice-Chairperson, Dr Grey Magaiza.

The operating days of the on-campus vaccination site have been extended to accommodate streams of incoming students who still want to be vaccinated.

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.
