Lerato Sheila Thamahane.

Lerato Thamahane may be able to speak and understand all nine of South Africa’s official African languages, but it is a tenth language she is devoting her life to: South African Sign Language (SASL).

With nearly ten years’ experience as a SASL interpreter in several settings – ranging from the medical and mental-health fields to that of conferences and Deafblind interpreting – Lerato is living her life’s purpose. “I regard myself as a member of the Deaf community and a servant at the same time.”

Lerato lives by the principle that the more perspectives she gains on the world, the better service as an interpreter she can provide. This is also part of the reason why Lerato decided to take on the role of student again to study BA Language Practice to provide her with an even broader perspective on the field. 

But why does Lerato feel so strongly about SASL? It is only through Sign Language, Lerato explains, that one can bridge the divide between the world of the hearing and that of the Deaf. “SASL is the only way for the minority Deaf group to receive and transfer information,” Lerato emphasises. “Deaf people cannot communicate in any other way.” Now, consider for a moment the plight of a Deaf child in South Africa. To receive education in SASL, most Deaf children have to move far away from home at a very young age in order to attend a school for the Deaf. For many years, schools for the Deaf did not include other languages as subjects, which prevented Deaf school-leavers from entering higher education. Although this situation has largely changed, Deaf students are still fighting an uphill battle when entering higher education institutions where prejudice and ignorance still persist. This is where the work of the Centre for Universal Access and Disability Support (CUADS) and the Department of South African Sign Language (SASL) and Deaf Studies makes such a crucial difference.

“I firmly believe,” Lerato says, “that only Sign Language can open opportunities for all groups of the Deaf community – from Deaf children to adults, and from the uneducated to the most educated Deaf people.” It is for this reason, Lerato argues, that our constitution needs to recognise SASL in order to give Deaf people full and equal access to information, to education, and ultimately, to all the opportunities South Africa has to offer.

Prof Tredoux turns theories regarding the formation of metals on its head

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.
