Fire
Fire facts: Assuming stable fuel, heat, and oxygen levels, a typical house fire will double in size every minute.


There are certain incidents that you cannot prevent from happening in life. However, in case the worst happens, you can always be well-prepared to take the right action. Fire outbreaks are a case in point. 

Certain rules apply to mitigate risks that may cause bodily harm. As a student, the University of the Free State is committed to ensuring that your well-being is taken care of.

In case of a fire, here are a few tips to remember:
1. Know your emergency evacuation plan
2. Know the fire brigade’s number 
3. Trust your Protection Services, notify them ASAP
4. Never waste time. Get up and get out
5. Wait to be accounted for at designated assembly point
6. Go low and never breathe in smoke, all smoke is toxic 
7. Close all windows and doors in case of a fire
8. Alert everyone in the building through the alarm system
9. Know your emergency exists and use them
10. Never try to be a hero, save yourself first

Once you are safe and sound, refrain from posting on social media before Emergency Services arrive. You are urged to obey these safety rules in all buildings and residences on campus.

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.
