Mr Steve Strauss, an alumnus from the Department of Economics and Finance at the University of the Free State (UFS) who donated one of his paintings to the department, pictured with Dr Nico Keyser, head of the Department of Economics and Finance with the painting.

The office of the Head of the Department of Economics and Finance in the University of the Free State (UFS) Faculty of Economic and Management Sciences received a new piece of art in the form of a flower painting donated by an alumnus. 

Steve Strauss, who is now a fulltime painter, donated one of his paintings to the department from which he graduated in 1989 with a degree in BCom Economics. Strauss, who started painting as a hobby while still a student at the UFS, enjoys painting flowers because it reminds him of his mother’s garden.

Dr Nico Keyser, head of the Department of Economics and Finance, says he is delighted that alumni still want to be part of the department and the university. “It points to the extraordinary role that the years at the university have played in one's life, and also the diverse talents that people have besides the academy. Steve enjoyed his years at the university, as they were wonderful years. That is why he decided to donate the painting,” says Dr Keyser.

According to Dr Keyser, Strauss enrolled for a few formal and informal classes from 2011 and now has a studio on the farm in the Schweizer-Reneke district where he lives. 

“Steve Strauss’s motivation to start painting was to express his God-given talent. He is currently a full-time artist, and his work is on display at various galleries in Clarence, Kimberley and Johannesburg. He often attends art festivals to exhibit his paintings. 

“The painting will be on display in the HoD’s office. The donation is much appreciated by the department, and so is all involvement of alumni students in the department. I hope that the future HODs will also find joy from the painting,” says Dr Keyser.

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.
