Tharina van der Walt
Tharina van der Walt, a first-year student, won the hammer-throw item at the first Varsity Athletics meeting in Stellenbosch on Friday – the only gold medal for the Kovsies.

Hammer thrower Tharina van der Walt was the bright spark for the University of the Free State (UFS) at the first Varsity Athletics meeting in Stellenbosch on Friday.

Van der Walt, who recently turned 19 and is one of three first-year students in the UFS team of 25 athletes, bagged the only gold medal for the Free State students. She won the hammer throw with a distance of 53,12 m.

The UFS ended in fourth place behind NWU (first), UJ (second), and Tuks (third).

Six athletes achieved second places. Both Sokwakana Mogwasi (100 m) and Ts’epang Sello (800 m) came within a whisker of claiming victory.  Mogwasi lost the 100 m by 00:04 seconds, but in the process improved her personal best from 11,89 to 11,58. Sello (2:08,47) was in the lead for most of the 800 m but was eventually defeated by Niene Muller of Tuks by less than half a second.

Mogwasi was also second in the 200 m with a fast 24,92. Other silver medals were obtained by Yolandi Stander in the discus (52,70 m), Peter Makgato in the long jump (7,66 m), and Marné Mentz in a very fast 1500 m race. Mentz (04:26,63) chopped more than five seconds off her previous best time of 4:32,00. Her time was the third fastest ever in the 1 500 m at Varsity Athletics.

There were three third places: Sefako Mokhosoa (15,47 – triple jump), Petrus Jacobs (14,55 – 110 m hurdles), and the women’s 4x100 m relay team (Mogwasi, Elsabé du Plessis, Joviale Mbisha, and Micháela Wright).

Four athletes just missed out on podium positions, achieving fourth places.

The second Varsity athletics meeting will take place in Potchefstroom on 15 March 2019.

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.
