Muhammad Cassim, a second-year student in the Department of Engineering Sciences in the Faculty of Natural and Agricultural Sciences at the University of the Free State, will participate in the winter university project in Pskov, Russia, from 25 November to 9 December 2024.

The winter school aims to strengthen relationships among young engineers and deepen international interaction via skills improvement, joint projects, and social cohesion. The programme boasts a densely packed education block, project block, and cultural block.

Cassim is part of the UFS Grid Related Research Group and actively participates in research centred on complexity science. He intends to complete his BSc Physics degree with Engineering subjects and progress towards postgraduate studies in the UFS Department of Physics.

He is currently working on verifying experimental developments in the field of synchronisation in complex networks. While he has already completed this high-performance computing training in his first year under the leadership of Albert van Eck (Director, UFS E-research), he is looking forward to the masterclasses in holographic modelling, deep learning, direct laser deposition, and database. Closely resembling his current research, he will have the opportunity to gain more experience in the use of set theory and graph theory in solving digital information processing problems.

For more information about international scholarships for study abroad opportunities, contact Mbali Moiketsi in the Office for International Affairs.

Cassim’s student profile is the culmination of the department’s strategy to produce young applied scientists who are subjected to the culture of research during their undergraduate study and could articulate with ease to other departments for postgraduate studies.  The department aims to align with the UFS’ Vision 130 by producing competitive students who can operate in the postgraduate paradigm with the digital themes of veterinary science and ecological engineering science.

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.
