Solar charging stations ready for use
Students and staff will be able to enjoy the new social space equipped for studying or leisure activities.
Solar charging stations were recently launched on the Bloemfontein Campus. These units can be used by students to charge their phones, tablets, and iPads. Solar charging units will be installed on the University of the Free State’s Bloemfontein, South, and Qwaqwa Campuses.

Social spaces make for happy faces

A new central social space where students can eat, socialise, study, and relax is one of several exciting developments that UFS students can look forward to on campus. The social space can be found in the open area between the Biology Building, Chemistry Building, and the West Block on the Bloemfontein Campus.*

“The space consists of concrete benches with roof coverings, paving, and electrical supply points fed by solar power for students to charge their cellphones or laptops,” says Maureen Khati, Assistant Director: Project Management, Facilities Planning.

Solar panels have already been installed on top of various buildings on all three campuses, for example, 1 280 solar panels on the roof of the Thakaneng Bridge on the Bloemfontein Campus. The computer laboratories and the projected Afromontane Research Centre on the Bloemfontein and Qwaqwa Campuses will be equipped with freestanding solar roof solutions.

The project was a collaborative effort between the UFS and FCE Consulting Engineers. Coenie van der Merwe, Prototype Design Engineer, played a vital role in designing the charging unit.

Project to enhance sustainability and address student needs

Prof Nicky Morgan, former Vice-Rector: Operations, says, “This should be a symbol of affordable opportunities that will both save the planet and enhance financial sustainability.” Nico van Rensburg, Senior Director of University Estates, says, “This renewable energy project is an innovative way of addressing student needs.”

However, students are advised not to charge other electrical appliances besides their phones and iPads at the charging stations, as this may cause the charging unit to trip.

The UFS was recently awarded for its contribution towards sustainability. This was in recognition of its amazing initiative to install and operate photovoltaic (PV) and greywater systems on all three of its campuses.

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.
