The Faculty of Natural and Agricultural Sciences held its very first virtual Academic Awards Ceremony this year, where 103 prizes were awarded in 75 different categories. Prof Danie Vermeulen sponsored the award for the best undergraduate student in the faculty.

The Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS) presented its very first virtual Academic Awards Ceremony this year, celebrating the achievements of students.

According to Tracy Isaacs and Heidiry White, both from the Office of the Dean: Natural and Agricultural Sciences and organisers of the event, the aim of this event is to award and reward skills, knowledge, talent, and abilities. They believe the event contributes to encourage, inspire, and motivate other students to excel.

“Academic awards in the faculty create meaningful moments of recognition that inspire others and reinforce the behaviour that led to the reward. Rewarding students for their hard work forms an integral part of creating a competitive spirit among students. Competition is essential, as it encourages every student to do their best to stand out,” says Isaacs. 

Support and innovation

During this year’s ceremony, 103 prizes were awarded in 75 different categories. Dedicated academic staff who went the extra mile to ensure that no student was left behind, played a major role in the faculty awarding this number of prizes. 

The quality of the programmes and the curriculum, together with innovative teaching and learning activities and approaches, form the basis for academic excellence in the faculty. Lecturers and students are also provided with ongoing support and proper resources to maintain a high quality of teaching.

An achievement that stood out was the work of Philip Schall, who received the Dean’s Award for best undergraduate student in the faculty. Schall obtained his degree with distinction. The Dean, Prof Danie Vermeulen, sponsored this award.

Search for knowledge encouraged

Lecturers and researchers encourage students on a daily basis to pursue academic excellence by challenging them to obtain the highest level of success in their work. 

Students are also provided with an academic, creative, and enterprising spirit that not only prepares them for their academic journey, but also for the world of work. “While being exposed to a range of valuable and relevant learning experiences, students are prepared for further study, ongoing learning, and for their future work environment,” says Isaacs.

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.
