Springboks
Prof Francis Petersen, UFS Rector and Vice-Chancellor, paid a special visit to the Springboks in 2018 before they faced England in Bloemfontein. From the left are Jacques Nienaber (Springbok assistant coach), Oupa Mohoje (Springbok), Prof Petersen, Rassie Erasmus (Springbok head coach), and Swys de Bruin (Springbok consultant coach at the time). De Bruin, Erasmus, Nienaber, and Mohoje are all Kovsie alumni.

Like the rest of the country, we are behind our Springboks all the way. This is what Prof Francis Petersen, Rector and Vice-Chancellor of the University of the Free State (UFS), told alumnus Rassie Erasmus in a letter this week.

Prof Petersen wrote the letter to Erasmus, the head coach of the Springboks, to wish him everything of the best in the team’s preparation and for the game on Saturday (2 November 2019) at which they face England in the Rugby World Cup final in Japan.

"On behalf of the staff and students of the University of the Free State, I would like to wish you and the Springbok team all the best with your preparations this week and for the final. I know that Saturday’s match will be played with vigour and determination,” Prof Petersen wrote.

Prof Petersen said the UFS community was extremely proud of the Springboks’ achievements during the 2019 Rugby World Cup – especially with Erasmus at the helm of the team. The Boks defeated Japan in the quarter-final and Wales in the semi-final to reach their first final since 2007.

“As a former Shimla player and Kovsie Alumnus of the Year 1998, we are truly proud of what you have achieved during your career in South African rugby, and especially during the World Cup tournament. We are also proud of our other alumni – Jacques Nienaber as defence coach, and referee Jaco Peyper.”

Peyper refereed one of the quarter-finals and will be an assistant referee in the bronze medal play-off between New Zealand and Wales on 1 November 2019.

Under Erasmus the Springboks won the Rugby Championship this year, the first time since 2010. Erasmus and Nienaber have a long relationship. They met in the army in 1991. Later Nienaber served as physiotherapist with the Shimlas and Erasmus captained the team. They worked together at the Cheetahs, Cats, Stormers, Munster and now the Springboks.

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.
