EMS graduation
Jan Johannes van Niekerk and Pierré Ludwig Koekemoer

This year, two proud recipients of the Dean’s Medal were honoured during the 2020 UFS Virtual Graduation Ceremony. Jan Johannes van Niekerk received the award for the best results in respect of a Bachelor’s Degree in the Faculty of Economic and Management Sciences (Bachelor of Accounting), and Pierré Ludwig Koekemoer was awarded the medal for the student who achieved the best results in respect of a Bachelor Honours Degree in the Faculty of Economic and Management Sciences (Bachelor of Commerce Honours with specialisation in Marketing).

Prior to commencing his studies at the UFS, Van Niekerk attended Fichardt Park High School in Bloemfontein.  Van Niekerk describes his time thus far as a student in the School of Accountancy as “nothing less than special”.  He adds that “… the support from the lecturers is really great … every lecturer has always tried to help me to the best of their ability!”

His favourite subject is Financial Accounting, and his Financial Accounting lecturers inspired him to follow in their footsteps; accordingly, he became a Financial Accounting tutor in his second and third years of study.  “As academic staff, we have come to know Johan as a pleasant and well-mannered, diligent, and hardworking student who pays attention to detail,” says Prof Frans Prinsloo, Director: School of Accountancy.

Johan is completing his BAcc Honours studies this year and will commence his training contract with Enslins Auditors in 2021 to qualify as a chartered accountant (SA).

“Pierré Koekemoer is one of the most decent young men I’ve met in years.  Hardworking, diligent, and one of the most respectful and responsible people I know,” says Prof Brownhilder Neneh, Associate Professor in the Department of Business Management.

Pierre Koekemoer was identified as the Best Honours Student for 2019 in the School of Accountancy, as well as the student with the best Honours script.  Koekemoer excelled during his Honours year, and successfully managed his responsibilities as student assistant/marker; he was also part of the City Lodge Marketing project that took place during the second semester.  

The General Manager of the Fairview Hotel in Nairobi, Kenia, offered Koekemoer a short internship at the beginning of 2020, as he was impressed with his performance.  Koekemoer could not accept the job, as he had obtained permanent employment and did not want to lose the position. “This also speaks of his integrity, as he had already committed to the company,” comments Prof Neneh.

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.
