Dr Lazlo Passemiers
Dr Lazlo Passemiers spent six years conducting research across three continents.

A keen interest in unravelling transnational histories of 20th-century Southern Africa led Postdoctoral Research Fellow Dr Lazlo Passemiers to spend six years conducting extensive research across three continents. Dr Passemiers sifted through archives in Africa, Europe, and the US in order to convert his PhD thesis into a monograph.

It was on 17 July 2019 that the fruits of Passemiers’ labour were officially launched by the International Studies Group at the University of the Free State’s Bloemfontein Campus. His book, Decolonisation and Regional Geopolitics: South Africa and the ‘Congo Crisis’, 1960-1965, offers an important shift in the historiography of the Congo Crisis. It creatively centres African involvement in the debate by examining this event from a regional geopolitical angle. 

Going back in time 

By providing a three-fold perspective that examines decolonisation, apartheid diplomacy, and Southern African nationalist movements, the book offers a rounded picture of South African involvement in the Congo Crisis.

Dr Passemiers’ fascination with the transnational dynamics of Southern Africa’s history has rippled into two new research projects that respectively explore “the connection between decolonisation and white flight in the region as well as the transnational support networks of liberation movements”.

Finding the missing pieces of the puzzle

Prof Christopher Saunders, Emeritus Professor at the University of Cape Town, commended Dr Passemiers’ historiographical contribution: “He has identified a major gap in the literature and he has filled it admirably by looking across the spectrum.” As Prof Saunders noted, “what has been missing in the literature is the African angle.” 

Literature’s role in transformation

The process of undoing the profound impact of colonialism on society is long and difficult and important in this process is a clear understanding of history, which Dr Passemiers’ book enhances.

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.
