Expert panel
The panellists appointed for a three-year term, are from the left: Gert Coetzee, Adv Henriëtte Murray, Prof Angelique van Niekerk (Head of Department), Liezel Meintjes and Estelle Zwiegers.

A hundred years after Afrikaans was first offered as part of the subject Dutch at the UFS in 1919, the department (the oldest Afrikaans language department in South Africa) appointed a practice panel. The panel consists of experts from the corporate world, namely an advocate, a teacher, a newspaper editor, and a publisher. They all have one thing in common, viz. their linguistic underpinnings and language qualifications, and their general emphasis on the need for language teaching and proficiency (also in Afrikaans) in the professional sector.

On Friday 4 October 2019, the practice panel, including Adv. Henriëtte Murray (senior advocate and acting judge in the Bloemfontein High Court), Gert Coetzee (editor of Volksblad), Estelle Zwiegers (Afrikaans teacher at Fichardt Park High School – subject adviser for the Free State from 2020), and Liezel Meintjes (chief executive officer of SUN MeDIA Bloemfontein) informed senior students and staff about the importance and relevance of language, language proficiency, and vocational demands in terms of language.

The panel was appointed for a term of three years. “We will annually invite the practice panel to the postgraduate meeting with new postgraduate students, as well as to an annual meeting with senior students and staff to reflect on new plans and opportunities for students regarding practice requirements,” says Prof Angelique van Niekerk, Head of the Department of Afrikaans and Dutch, German and French at the UFS. 

Importance of language proficiency

‘The role of language in different professions’ was the topic of the discussion, during which panel members emphasised the importance of language proficiency. Language knowledge and proficiency form the essence of the legal profession. “Language proficiency is crucial to understand words not yet included in legal terminology,” Adv. Murray said. She also stressed that students should acquire the required language knowledge, since the interpretation of words could irrevocably affect people’s lives. Using examples from practice, she also pointed out the importance of teaching language structure (syntax and morphology). 

As much as language proficiency is important in the legal profession, it is naturally also of great importance in journalism. Gert Coetzee, editor of Volksblad, has years of experience in the newspaper industry and considers the skilled ‘wordsmith’ as a great asset to fulfil the watchdog role of the media through a fascinating presentation of facts.  Estelle Zwiegers, an Afrikaans teacher, emphasised the importance of language education at school level, saying that good knowledge and understanding of the way mother tongue is used for communication purposes, is of great value for learners – also at tertiary level. 

With the appointment of this practice panel, the Department of Afrikaans and Dutch, German and French is responding to contextual changes in the tertiary education sector.

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.
