Prof Johann Rossouw Inaugural lecture

For Prof Johann Rossouw from the Department of Philosophy, the Naval Hill Planetarium – a digital planetarium on a hill in the centre of a modern city, was the perfect place to deliver his inaugural lecture titled, The soul of the academy.

The message of his inaugural lecture was on “the form adopted by the contemporary university, which is so focused on the quantitative that the qualitative is neglected. The focus on training is so strong that the university no longer pays attention to the education of students”.

Prof Rossouw referred to the soul of the academy as the highest in humanity, especially the part which cannot be counted. He also referred to the words of Blaise Pascal in the 17th century: “The heart has its reasons of which reason knows nothing”.

“Do we understand any of this in the contemporary university? And do we still remember the earliest origins from which the academy originated; that Philosophy is the mother discipline of all other disciplines, and how all contemporary disciplines form part of a bigger, coherent entity?” he asked.

The inaugural lecture took place on 28 February 2019. Prof Rossouw has a C2-rating from the National Research Foundation, and it is thanks to him, among other things, that the Department of Philosophy is the only South African Philosophy department with modernity studies as its main focus.

At the end of 2018, he was promoted to Professor of Philosophy at the University of the Free State (UFS), and currently he serves as acting Head of Department. “Due to Prof Rossouw’s involvement, among other things, research on African philosophy, critical theory, postcolonial thinking, and tradition and modernity is conducted in the department,” Prof Heidi Hudson (Dean: the Humanities) said.

Prof Rossouw started his formal training in Philosophy at the age of 12, and in 1991 he obtained a BA degree majoring in Philosophy and Psychology at the University of Pretoria, with distinction. He obtained his MA degree, a critical study of apartheid on the basis of Michel Foucault’s thinking, at Unisa in 1998. In 2002, he obtained his DEA in Philosophy at the University of Lyon 3 under the leadership of Régis Debray, and in 2013 his PHD on the theological trail in Bernard Stiegler’s thinking at Monsh University (Melbourne), under Michael Janover.

In 2016, he won a prize from the South African Academy for Science and Culture for one of the best Afrikaans humanity articles published in 2015.

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.
