As students are returning to campus, Cobus van Jaarsveld, Assistant Director: Threat Detection, Investigations and Liaison at Protection Services, believes it is important that they ‘know’ and practise safety at the UFS:

1) Know the number of your Department of Protection Services:

• Bloemfontein Campus: +27 51 401 2911(also in cases of GBV)
• Qwaqwa Campus: +27 58 718 5032 / 5029 / 5033
• South Campus: +27 51 505 1298

Protection Services staff are the experts on campus safety, and they are able to point out the safest routes on and around campus, especially after dark. They can also assist with any safety concerns you may have.

As a student, you are smart; use your senses:
o Never let a stranger in your room or apartment
o Never walk alone after dark.

2) Know how to use alcohol

Although drinking and driving is a big NO, there are some other cardinal facts about drinking that you need to take note of:

• Never consume a drink provided by a stranger
• Never leave a drink unattended
• Never drink too much too quickly
• Always leave a party with a buddy

3) Know the basics of personal finance

You will be bombarded with offers from credit card companies, clothing stores, etc. Know how to budget. If you do not know how to budget, please contact the Student Counselling and Development office to assist you. This skill will not only make your life easier at varsity, but also once you start earning an income.

Be aware of fraud. If something looks too good to be true, it often is.

Watch your wallet. Theft or robbery is a possibility.

4) Know how to be safe on the internet

You are spending a lot of time on the internet. Unfortunately, criminals are also spending time in cyberspace with the aim of taking advantage of unsuspecting people like you. This may include cyberstalking, which may lead to emotional or physical harm, or it may result in them taking your information or money through phishing scams. Do not become a victim and ensure that you
- never use the same password twice;
- never use unsecured Wi-Fi to access private accounts;
- always use passwords that are difficult to guess;
- never reveal important information such as your banking login details to strangers calling on the phone; and
- never mention your location online.

5) Know basic self-defence

Avoid being the victim of any form of harassment or assault. Learning basic self-defence techniques will help you to protect yourself from physical attacks.

Protection Services offer self-defence classes from time to time. Make use of the opportunity and equip yourself with these self-defence techniques. Also buy yourself pepper spray, which can give you time to escape.

“Lastly, be aware of your surroundings. Walk with a purpose, without headphones, and always pay attention,” says Van Jaarsveld.

In future, stargazers and astronomers will look at the Scorpius constellation near the Milky Way with new eyes. Earlier this year, a group of international astronomers announced the discovery of an exotic binary star system, AR Scorpii. The system is in the Scorpius constellation.

Prof Pieter Meintjes, researcher in the Department of Physics at the University of the Free State (UFS), worked with four colleagues on what he describes as a “wonderful discovery”. This sensational discovery, which could lead to the production of cleaner energy on Earth, will be published in the research journal, Nature, early in 2017.

Model developed to interpret new set of measurements
The exotic binary star which was discovered consists of a red dwarf and a white dwarf revolving around each other every 3,5 hours. The binary system showed very prominent pulsations of 117 and 118 seconds respectively. The pulsations can be explained by a bundle radiation produced by the white dwarf star.

“These new observations have shown that the radiation is strongly polarised, a sign that we are dealing with synchrotron radiation here. Synchrotron radiation is produced by electrons accelerated to extremely high energy levels in the magnetic field of the white dwarf star,” says Prof Meintjes.

He developed a theoretical model to interpret a new set of measurements that was taken by the 1,9 m telescope and the 10 m SALT telescope at the South African Astronomical Observatory (SAA0).

Totally unique phenomenon could contribute to energy production on Earth
“I further indicated that the interaction between the magnetic fields of the white dwarf star and the red dwarf star induces secondary processes that specifically describe the behaviour of the radiation in the radio band and infrared band accurately. AR Sco is the first white-red dwarf binary system of which all the pulsated radiation could be explained by the synchrotron process, which is totally unique,” says Prof Meintjes.

According to Prof Meintjes, the value of the model lies in the fact that the processes which produce the radiation in AR Sco, can also be applied to produce energy on Earth.

 

Plasma reactors are based on roughly the same processes which apply in AR Sco, and with refining, it could be utilised to generate electricity in future. This will be much cleaner than nuclear energy.

 

The model developed by Prof Meintjes explains all the radiation in the system – from radio waves to X-rays – in terms of electrons accelerated to extremely high energy levels by electric fields in the system, which then produce synchrotron radiation over a very wide band of the electromagnetic spectrum.

Prof Meintjes is currently working on a follow-up article examining the evolution of the AR Sco, in other words, the origin of such a unique system and the final state towards which it is evolving. “My vision for the immediate future is therefore to develop a model for the evolution of the source concerned,” he says.
