The very comprehensive publication, JC Steyn en Afrikaans – ’n viering, pays tribute to a leading figure of the Afrikaans academic world. The book, edited by Profs Angelique van Niekerk, Hennie van Coller, and Bernard Odendaal, was recently launched at the University of the Free State (UFS) as a tribute to Prof Jaap Steyn, research fellow and former colleague at the UFS.

“The publication contains diverse contributions and provides a comprehensive overview of the different types of research in Afrikaans literature and linguistics,” said Prof van Niekerk, Head of the Department of Afrikaans and Dutch, German and French at the UFS. 

The scope of the contributions is as wide as the influence Prof Steyn has had on the Afrikaans language landscape. “Creative writing and biographies lexicography and sociolinguistics are addressed in his book,” Prof van Niekerk said.

As mentioned in the title, the publication serves as a celebration of Afrikaans as a language and discipline; it also covers the research areas in which Prof Steyn used to publish research himself.

The book, published by SUN MeDIA, was made possible by a financial donation from the South African Academy for Science and Art. It was officially launched at the UFS on Wednesday 16 October 2019. 

More about Prof Steyn 

Prof Steyn is a seasoned poet, writer, and one of the leading Afrikaans academics in the country. With more than 100 articles in scientific journals to his name, Prof Steyn is still serving as research fellow in the UFS Department of Afrikaans and Dutch, German and French. He is also the author of, among others, books on language politics, language, and cultural history, such as Tuiste in eie taal, Trouwe Afrikaners: Aspekte van Afrikanernasionalisme en Suid-Afrikaanse taalpolitiek and the recent Ons gaan ’n taal maak. He has also written a number of award-winning biographies and published prose and poetry. 

Prof Steyn has been associated with several South African universities, including the University of Johannesburg (the then Rand Afrikaans Universiteit), Nelson Mandela University (the then University of Port Elizabeth), as well as the UFS.

Three heart-valve studies which have been developed at the Robert WM Frater Cardiovascular Research Centre at the School of Medicine at the University of the Free State (UFS) were recently presented in Monte Carlo at the conference of the prestigious global Heart Valve Society (HVS).

These studies are all headed by Prof Francis Smit, Head of the Department of Cardiothoracic Surgery at the UFS, and Manager of the Robert WM Frater Cardiovascular Research Centre.
Prof Smit says the HVS is a combination of the former heart-valve societies of Europe and the US. “Studies on heart-valve disease, heart-valve-related products and operations, as well as the design and development of new valves were presented. There are both clinical and development divisions.

He says the study in which the hemodynamics of their redesigned mechanical poppet valve was compared to a commercial bi-leaflet mechanical heart valve, was named as the best poster presentation in the experimental valve development and numerical flow dynamics division. The study, which was presented by Kyle Davis, mechanical engineer at the centre, competed against some of the best heart-valve research units in the world.

The redesigned valve, based on the 1960s Cape Town poppet valve, has the potential to provide a low-cost solution for mechanical heart-valve replacement. It is possible to produce the titanium ring with 3-D printers and is, together with the silicon poppet valve, extremely inexpensive compared to current mechanical valve-manufacturing processes.
The advantages of this valve over current mechanical valves is that, due to the effective and laminar flow characteristics, as well as the simple locking mechanisms, there is a reduced chance of valve thrombosis, and the need for anti-clotting drugs is therefore limited.

It was also confirmed that the new valve more than meets the published FDA (Federal Drug Agency) requirements, which determine the minimum standards of valves for human use in the US.

The redesigned valve also has a very low platelet activation impact, which is responsible for platelet thrombosis and leads to valve thrombosis or strokes. This valve is another heart-valve project by the centre, which is also in the process of evaluating a tri-leaflet polyurethane valve developed by them.
