The South African National Press Club recently hosted the University of the Free State’s Rector and Vice-Chancellor, Prof Francis Petersen, at a gathering of national media representatives and communication specialists in Pretoria. Following a recent, widely publicised opinion article about the importance of the youth vote, Prof Petersen reflected on the period following the national elections of 8 May 2019, sharing his insights from a higher-education perspective.

“The role of the modern university has shifted”, said Prof Petersen, as he outlined five things the UFS was actively pursuing through its Strategic Plan and Integrated Transformation Plan.

New Knowledge

The UFS will develop a new knowledge (research) industry. For South Africa to yield economic growth, it must support the growth of small and medium enterprise. The institution has an active role to play in yielding this new knowledge as reflected in its recent launch of the Agribusiness Transformation Programme with Standard Bank; Applying our knowledge in the Natural and Agricultural Sciences and Business; we will equip and empower 25 black commercial farmers in addressing food insecurity.  The annual Thought-Leadership Series during the Vrystaat Arts Festival in July 2019 will also address economic growth, entrepreneurship, and employment.

Practical Application 

“Once we have trained people for the economy and have delivered research, we must ensure that our knowledge is appropriately disseminated technical academic papers need to be converted to something useful, appropriate, and practically applicable”, he said. 

Public Discourse 

Creating a platform to address controversial issues in our society is what defines the UFS as a thought leader.  As demonstrated by the recent Gangster State Book Discussion by author Pieter-Louis Myburgh hosted by the Business School, the institution continues to demonstrate its’ commitment to intellectually engage society through public discourse. 

Projects 

The institution actively pursues interesting projects that will shift the thinking of general society, government and industry. “These address our response to transformation, informs strategic planning, and shapes our values as we create a new university citizenship – a transformed society of inclusivity and belonging,” he said.

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.
