Prof Rodwell Makombe, Associate Professor in the Department of English on the Qwaqwa Campus.

Prof Rodwell Makombe, Associate Professor in the Department of English on the university’s Qwaqwa Campus, will be joining a prestigious group of more than 100 academic staff from African universities for this year’s University of Michigan African Presidential Scholars (UMAPS) programme.

Each year, the programme hosts more than 180 academics from different universities in Africa for a five-month fellowship, providing academics with access to the university’s research libraries and facilities, on-campus housing, health insurance, and a stipend to cover living expenses.

Fellowship an opportunity for collaboration and career growth 
 
The fellowship comes at just the right time for Prof Makombe, who said he is looking forward to mentorship for his growth and career development in a new environment and atmosphere. “I am very excited about this opportunity, which I think has come at the right time. It will expose me to a broad network of scholars, which I need for collaboration purposes, and it will also give me an opportunity to share my research and learn from the experiences of other scholars from different parts of the world. Given that I will be working closely with a faculty member of the university for the duration of the fellowship, the programme will also provide me with the mentorship that I need for my growth and career development.”
 
Apart from the exposure to broad academic and research scholars, he said he was looking forward to having the time and resources to finish writing his second book.

“I have just published my first book in October 2021, and I have already started doing research for my second book. The fellowship will give me time and space to focus on writing the book without the usual interruptions associated with my teaching responsibilities. The book focuses on cultures of resistance in post-Mugabe Zimbabwe. It is a sequel to my recent book,Cultural texts of resistance in Zimbabwe: Music, Memes, Media, which explores discursive resistance in Zimbabwe in the context of crisis.”

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.
