If all works out, Kovsie student Stephan Diedericks could change the face of the Mangaung Metropolitan Muncipality’s transportation facilities and save the city millions in maintenance costs while generating income.

The Masters Architecture graduate designed an innovative model titled An Interminable Living Machine: Humanizing and Re-appropriating the dormant Mangaung Intermodal Transport Facility (MITF) into a living, economic systems of change which won him the Corobrik Regional Student of the Year Award. The awards ceremony was hosted by the UFS Department of Architecture on 22 November 2019 at the Bloemfontein Campus.

A living machine

Re-appropriating the Bloemfontein taxi terminal located in the Central Business District (CBD) which has been non-operational for a few years would mean that the building sustained itself, and acted a power generator both environmentally and economically. 

Diedericks was inspired by the need to improve the quality of life for the people of City of Roses. “This course helped to broaden my perspective on the power of architecture and the social change that it can bring to people's lives,” he said.

An environmentally-friendly concept

According to the young architect, the facility would be water efficient. “Bloemspruit channels run underneath the proposed site and water will be filtered through biologically that will provide water to the entire site creating a self-sufficient living building with water at its heart.”

A thriving economic hub

Diedrick’s 220-page thesis details how the site of the intervention was once home to Bloemfontein’s first power station and that it is this concept of power generation that led him to place clients at the centre of the project as a catalyst for change.  

“The Small, Medium and Micro Enterprise Business (SMME) division of the Free State Department of Economic, Small Business Development, Tourism and Environmental Affairs (DESTEA) serves as the catalyst and a power generator that breaks open the solid mass of the MITF. Several subsystems, including aquaponics and SMME training, feed of the main catalyst and in turn provide resources in the form of food and business training to ground-floor users and micro-enterprise users onto latch onto over many decades of growth,” he explained.
 
A bright future ahead

"The only thing that we have and you don’t is experience,” said Petria Smit, a lecturer at the Department. “Some of your talent far exceeds ours.” During the awards ceremony, she said it was a privilege to work with students of such impressive calibre.

The awards, which were hosted for the 32nd year, are a way for the Department, in collaboration with Corobrik, to reward the talent of students. Diedericks said his win was a great honour and worth the many hours he had sacrificed for this course. Having bagged his master’s, Diedericks’s future plans are to work for the City of Bloemfontein as an architect or on an urban level when an opportunity arises.

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.
