The science of safety reinforces practical and collaborative efforts aimed at creating a secure campus environment.

While we might not have it down to a science just yet, safety is something that the University of the Free State (UFS) is constantly working towards improving. As it stands, various preventative measures exist across our three campuses. They say “Prevention is better than cure” – and that is exactly what the science of safety is all about.

What is the university doing to prevent crime? 

There are a few measures put in place by the Department of Protection Services, as its core mandate involves working around the clock to address the state of safety and security for staff and students. Some of these measures include:
• CCTV cameras monitoring campuses on a 24/7 basis.
• Panic buttons mounted on red poles which are fitted with cameras linked to the Control Room.
• Daily visible vehicle and foot patrols conducted by security personnel. 
• Security infrastructure such as turnstiles and surveillance cameras installed on all residence entrances.
• Security officers deployed around residences at night.
• Closely collaborating with Housing and Residence Affairs to find ways of creating, maintaining, and improving off-campus student safety.
• Investigating Officer on a 24/7 standby who is in direct contact with the South African Police Service (SAPS) Investigation Unit.
• Security and SAPS vehicles deployed at identified hotspots.
• Security patrols by contracted armed response security companies conducted in areas such as Brandwag, Willows, and Universitas in Bloemfontein, and surrounding areas at the Qwaqwa and South Campuses.

Safety is a shared responsibility

“In as much as Protection Services has duties and responsibilities in ensuring the safety of staff and students, the UFS community also needs to support and provide assistance to the department,” said Cobus van Jaarsveld, the department’s Section Head: Threat Detection, Investigations, and Liaison. 

You can play a role in ensuring that the UFS becomes an increasingly safe environment by:

• Immediately reporting any suspicious activity, item, person, or vehicle to the Department of Protection Services. 
• Acting responsibly to minimise your vulnerability to criminal activities.
• Familiarising yourself and complying with the UFS Security Policy, Protest Management Policy, and other security guidelines, standards, procedures, and protocols. 
• Following instructions issued by an authorised person for safety and security reasons.
• Cooperating with investigation processes that are in the interest of justice.
• Treating university property with the utmost care and avoiding exposing it to criminal activities, as well as reporting such activities. 

Creating a safe space for all

From identifying safety needs to tackling security issues head-on, the Department of Protection Services strives to reduce the risk of all kinds of crimes through the science of safety. The department continuously responds to the call to serve and protect in the following ways:

• Identifying and assessing risks and threats that have an impact on the safety and security of the UFS staff, students, and property.
• Enforcing access control.
• Investigating any reported incidents, providing investigation reports, and also issuing early-warning reports.
• Responding to emergencies reported on campuses. 
• Advising UFS management on all aspects of security.
• Initiating programmes and projects to enhance security awareness among UFS staff, students, visitors, and contractors.
• Providing support to students living in off-campus residences through contracted armed response that responds to emergencies and conducts patrols.
• Arranging counselling for victims of crime where necessary.
• Coordinating security services for on-campus events to ensure a safe and secure environment.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
