UFS Debate Society
The UFS Debate Society led by example at the 2019 Jozi Rumble.

After competing in the Jozi Rumble final for six consecutive years, the UFS Debate Society won the competition – Africa’s largest intercollegiate debate open – for the second consecutive year. The tournament took place at the University of the Witwatersrand (Wits) in April 2019.

After seven preliminary rounds, three UFS teams out of a total of 100 competing teams overall were placed in the top 16, earning them a place in the quarterfinals – where they faced each other. A composite team of UFS LLB graduate and LLM student, Lehakoe Masedi, and a partner from Wits beat all teams, qualified for the final themed ‘This house regrets the glorification of opulence in popular culture’, and won the league.

“It was one of the most validating moments of my entire debating career; everybody wants to win the Jozi Rumble, and to have done it and to be the best speaker is truly amazing,” said Lehakoe. The top-ranking speaker at the tournament added that she had been working hard, and that she is glad that her efforts are coming full circle.

The UFS sent six teams overall to the tournament, including two novice teams competing in their first-ever intercollegiate debate tournament. 

“Speaking at the Jozi Rumble debate tournament for the first time was truly an educational experience; it exposed me to the dynamics of varsity-level debating,” said Simphiwe Yana, debater in of the UFS novice teams.

The UFS speaking squad consisted of Lehakoe Masedi, 2018 Abe Bailey Bursary victor and Rhodes scholarship recipient Nkahiseng Ralepeli, Khotso Khokho, Siyanda Rixana, Morena Moabi, Simphiwe Yana, Luvuyo Shoco, Asemahle Noholoza, and Nontobeko Msimangu. Former Chairperson of the UFS Debate Society and Editor-in-Chief of the IRAWA newspaper, Tshiamo Malatji, was also present at the tournament as the Tabulation Director. 

On 11 May 2019, the UFS will travel to the University of Pretoria to defend yet another debate open title at the Pretoria Parlay Intervarsity.

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.
