The University of the Free State’s (UFS) Prof Hussein Solomon scooped a prestigious Best Published Book award for his critical analysis on the nature of environments, challenges, and opportunities facing the African continent in his book.

Titled African Security in the Twenty-First Century: Challenges and Opportunities, UFS Vice-Rector: Research, Innovation, and Internationalisation, Prof Corli Witthuhn, hailed the book as “An ambitious and in-depth study covering several regions, and with due regard for changing contexts and relevant historical legacies. This analysis is perspicacious, conceptually sophisticated, and based on a solid range of sources.”

UFS awards to stimulate staff creativity

Prof Solomon is a Senior Professor in the Department of Political Studies and Governance. The annual UFS 2018 Book Prize and Research Support Awards is aimed at recognising outstanding contributions by staff members in these focus areas.
Prof Witthuhn congratulated the winners and all the participants who spent time on their submitted work.

The other two entries in the Best Published Book category were Prof Philippe Burger, the Head of the Department of Economics and Finance, for his book titled, Getting it Right: A new economy for South Africa.

The other published book entry was that of Prof Jacobus Naudé, a Senior Lecturer in the Department of Hebrew in the Faculty of the Humanities, titled, A Biblical Hebrew Reference Grammar.

Winning author’s analysis impressive

Prof Witthuhn said the author of the winning book employed a human security approach which not only examined and analysed these challenges, but also assessed the effectiveness of solutions and progress in addressing these challenges.

“This approach is critical to understanding the true meaning and context of security in Africa, by asking questions such as: security for whom and security for what?”

Bouwer comes top in research support category

Ms Annatjie Bouwer, a Research Officer in the Department of Paediatrics and Child Health in the Faculty of Health Sciences, emerged victorious among the nine entrants from various faculties. 

Her award was for the support she offered to the broad community of researchers within the Faculty of Health Sciences.

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.
