Dr Nomalungelo Ngubane, the Director: Academy for Multilingualism, is working through various initiatives to ensure that the UFS becomes and remains the South African leader in multilingualism.

The Academy for Multilingualism was established at the beginning of 2021, flowing from the UFS Language Policy (2016) that is currently under review, and which expresses the university’s commitment to multilingualism, with a particular emphasis on Sesotho, Afrikaans, and isiZulu, while English remains the primary medium of instruction for undergraduate and postgraduate studies.

The Student Language Preference Survey continues to indicate that many students have difficulty understanding English lectures due to language differences. Multilingual models from places like South America, India and South Africa were considered in order to structure the approach at the UFS.

Promoting indigenous languages

To mitigate the English barrier, the academy is developing multilingual academic glossaries. The multilingual glossaries are also intended to drive the promotion of indigenous languages (Sesotho/Afrikaans/IsiZulu) as academic languages, and to create multilingual learning spaces that embrace diverse languages.

Academic word lists from seven departments are in the process of being translated – in conjunction with the Unit of Lexicography – to create glossaries. The team at South African Sign Languages will add videos to these glossaries to provide unique and inclusive content in the realm of multilingualism. 

In 2022, the academy, in collaboration with the Library and Information Services, launched an African Languages Press with the aim of promoting and advancing publications of literature and research books using South African indigenous languages. 

The Academy for Multilingualism also promotes multilingualism through the Initiative for Creative African Narratives (iCAN), a programme that encourages students to write short stories in their indigenous home languages. By incorporating student narratives into learning material, students learn about one another, from one another.

The iCAN multilingual booklets are also used to encourage extensive reading among undergraduates and among learners in the surrounding community schools.

Use of translanguaging practices
 
The academy is also working with the Centre for Teaching and Learning’s (CTL) A_STEP programme to pilot the use of translanguaging practices in tutor sessions. UFS staff will also be trained on teaching and translanguaging practices. Voice-over translations of English lessons into Afrikaans and Sesotho in the Faculty of Theology and Religion paved the way for the academy to proceed with this practice in other subjects. The Translanguaging Seminar 2022, hosted by the academy and the CTL, was used as a platform for sharing translanguaging knowledge and practices by academics from the UFS and other institutions.

The Kovsies Multilingual Mokete has become a popular annual tradition celebrating different cultural expressions – in visual art, poetry, storytelling, drama, music, and song – by different language groups and in the different languages that are dominant at the UFS (i.e. English, Afrikaans, Sesotho, isiZulu, and Sign Language). This year’s event was held on the South Campus in October.

With its various initiatives, the Academy for Multilingualism will ensure that the UFS becomes and remains the South African leader in multilingualism.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
