Prof Jacobus Naude
Prof Jacobus Naudè is one of few South Africans who have delivered the Van Selms Memorial lecture at the Southern African Society Near Eastern Studies conference.
To be awarded an opportunity to present a lecture outside the domain of your own university is not only beneficial to attract new postgraduate students but also provides senior researchers with the opportunity to publicise their research on a national and sometimes international level.

This is the impression of Prof Jacobus Naudè, a senior professor in the Department of Hebrew at the University of the Free State (UFS) when he delivered the 2019 Adrianus van Selms Memorial lecture at the Southern African Society for Near Eastern Studies conference. Prof Naudè said such lectures provide an opportunity to academics and researchers to demonstrate that a particular field of study has broad implications for society. “A South African only has the opportunity to deliver this lecture every second year by invitation, so it’s a once-in-a-lifetime opportunity,” he said. 

His own research seeks to understand alterity (“otherness”) in various systems of ancient culture and to preserve it while representing it intelligibly for modern users. “In my current research I utilise complexity theory to integrate seemingly disparate foci (pre-modern Hebrew linguistics and religious translation).” 

The conference took place on 16 September 2019 at the School of Religion, Philosophy and Classics at the Pietermaritzburg Campus of the University of KwaZulu-Natal.

South African Bible translations through the ages

The topic of his lecture was, Translations of sacred texts and the shaping, reshaping and circulation of religious knowledge in monotheistic religions with written traditions: A Southern African perspective, in which he provided examples from the history of religious translations in monotheistic religions (Jewish religious tradition, Christianity and Islam) to “illustrate the spreading, circulation, shaping and reshaping of our religious knowledge by translation”.  

Prof Naudè shared some aspects of how religious ideas have travelled via the medium of translation into different cultures and languages. With his focus on South Africa he illustrated how the Dutch East India Company imposed monolingualism in the Cape with Dutch being the only language in church and at school. “There was complete unwillingness on the side of the Dutch to learn the Khoikhoi languages.” The political change in beginning of the 19th century provided strong motivation for Bible translations into indigenous languages. 

There have been many attempts to reconceptualise South African translations of the Bible. The latest attempt was by Prof Kobus Marais from the UFS Department of Linguistics and Language Practice whose work aims to reconceptualise translation within the frame of complexity thinking. “Religious translation will thus need to avoid reductionism and rather focus on the source or the target,” Prof Naudè said.

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.
