Vishuis
Vishuis will be trying to win their overall seventh Varsity hostel title on Monday.

Managing his players is of the utmost importance if the University of the Free State’s (UFS) Abraham Fischer Residence (Vishuis) is to claim a fourth straight and seventh overall national hostel title, says Zane Botha, head coach of the hostel team at the UFS.

The Varsity Hostel competition, which will be taking place in Stellenbosch, has been drastically shortened to only three days of rugby because Steinhoff has withdrawn their sponsorship.

If Vishuis makes it to the final, they will play three matches in four days.
They will face the Kovacs of the University of the Western Cape (UWC) on Friday 12 March 2019, followed by the semi-final on Saturday and the final on Monday. The final will take place at 14:00 and will be broadcast live on SuperSport.

“This will be new territory for us. We will have to make good tactical decisions; it won’t be possible for a prop to play for 70 minutes in all three encounters,” said Botha, who is in his third year with the hostel.

The team played three warm-up matches, which they won convincingly. We still have the core of last year’s team, together with some exciting youngsters.
Botha explained that they kept to their strategy of working harder than anyone else on the practice field and during matches. In last year’s final, Vishuis defeated Patria of the North-West University by 55-29, which was the biggest winning margin in the 11 years of the competition. Vishuis walked away with the crown in 2010, 2012, 2013, 2016, 2017, and 2018.

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.
