Dr Thandi Gumede
Dr Thandi Gumede graduated with a PhD in Polymer Science. She is from Intabazwe, Harrismith.

The Qwaqwa Campus of the University of the Free State was a hive of activity on 17 and 18 May 2019, when over 800 degrees, diplomas, and certificates were conferred on deserving achievers. These included six PhDs and 14 master’s degrees across the four faculties.

Congratulating the graduates on both days, was Africa’s youngest PhD and Industrial Psychology lecturer, Dr Musawenkosi Saurombe, and Prof Francis Petersen, Rector and Vice-Chancellor.

Be like heat

Dr Saurombe started her address by relating her school journey that saw her starting Grade 1 at age 5, thus later matriculating at the age of 15, having skipped Grades 3 and 10. She went on to emphasise the importance of building an honourable character.

“As a graduate, you will soon realise that your degree is useless if you do not have character,” she said to an attentive audience that continued to marvel at her remarkable school history. She encouraged graduates to be like heat that cannot be seen but can only be felt. “Noise can often be seen and heard, but it cannot be felt. However, while heat cannot always be seen, it is always felt. Be like heat and may your presence always be felt,” she said.

Do not focus on yourself

Prof Francis Petersen also encouraged graduates to look beyond their degrees by developing a set of critical values.
 
“For us as the university, this ceremony is not just about your degrees. It is about the values that you must live by,” he said. “As a graduate of the UFS, do not just believe what you are told. Ask questions and engage critically. Secondly, do not just focus on yourself. Remember that you are part of a community and it is your responsibility to make our world a better place for others. You need to be socially responsive to the needs of your community. Thirdly, remember that integrity plays a very important role. This will determine how others value you,” he said.

The two ceremonies also saw three current SRC members graduating. They are Lebohang Miya (BEd FET – Accounting and Business Studies), Duduzile Mhlongo (BA – Geography and isiZulu), and Mhlongo Sinemfundo (BA – Geography and isiZulu).

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.
