Abe Bailey Bursary victor
“I believe in self learning,” says 2018 UFS Abe Bailey victor, Nkahiseng Ralepeli.
The Abe Bailey Trust is a leadership-development opportunity that targets university students or junior lecturers who are academically strong and have shown exceptional qualities of leadership and service. Recipients of the bursary are required to have a good record of accomplishments, not only on campus but also in a broader social context, where they function as an integral piece of a select and highly-skilled group of individuals.

Ralepeli, the over-achiever

Final-year Law student, Nkahiseng Ralepeli, embodies this exact description and exemplifies the essence of distinction and merit when it comes to who he is. Ralepeli  who has represented the university at various international debate platforms, an alumni of the F1 programme to Thailand and other leadership programmes such, recently, International Youth Leadership Conference (IYLC) programme in Prague, will represent the University of the Free State (UFS) during the Abe Bailey Travel Bursary tour in the UK in December 2018. He, along with 16 other candidates from other South African tertiary institutions, will participate in the tour for its full duration and will take part in the exciting developmental programme that is planned.

With an intense but fruitful leadership-training schedule, he said he was looking forward to meeting the British members of parliament as well as other persons of stature in the British government.

Travelling: A catalyst for critical thinking

Ralepeli, who was also 3rd overall Kovsie Dux student, underlined that he truly enjoys travelling. He has subsequently mastered the art of constantly positioning himself among the best academically and socially, and this has aided his mission to trot the globe extensively, which he has been doing since his junior years.

A man of value

“I have a small yet select and impactful network of people in my life who play an influential role in reminding me during times of triumph that, while it is important to celebrate, each win is just a step towards the ultimate goal of success,” said Ralepeli. 

He emphasised the importance of the roles played by those close to him, describing them as “my double-edged sword who played a crucial role in carving out the inner Nkahiseng, who, hopefully, will do great things”. The Kovsie Dux believes that those you surround yourself with, channel the kind of energy that will either make or break you.

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.
