Qwaqwa Campus welcomes international students

Integration. Diversity. Inclusivity. Academic excellence.

These words featured prominently during the welcoming event for international students on the Qwaqwa Campus of the University of the Free State. The event was organised by the International Student Council (ISC), in collaboration with the Office for International Affairs (OIA).

“The presence of international students is bound to enrich diversity on campus, as it converges vast experiences of the world within one space. It further promotes social integration between South African students and those from the region and beyond,” said Teboho Manchu, Acting Campus Principal.

Opportunity to connect
Teboho further stated that international students provide a critical opportunity for all students to connect, irrespective of their origin.

“Immerse yourselves in the local culture and most importantly, go out there in the communities and connect with the ordinary people,” he added.

In encouraging international students to fully participate in the student programmes on campus, the Acting Campus Vice-Principal: Support Services and Director: Student Affairs, Temba Hlasho, said that Student Affairs supports all students, irrespective of their choice of study or origin.
“To show that we as Student Affairs care, we are going to institute a process in which the SRC Constitution will be reviewed to include international students. This will enable all students to use the positive environment to further thrive in their chosen careers. Participate in all the student activities and leave a mark. Exploit the nature of this campus. Take advantage of its relatively small size and warmth,” he said.

SRC Constitution review
In his response on behalf of the students, the SRC President, Masopha Hlalele, concurred with the campus management that the time was right to review the SRC Constitution to include international students as well as postgraduate students.

“We commit to fast-tracking this process so that the amended constitution can be adopted by the UFS Council in June 2018. In the meantime, continue making your mark on every inch of this campus,” he said.

International students in the audience came from the Southern African Development Community (SADC) region, Cameroon, Ethiopia, Kenya, Nigeria, Ghana, and India.

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.
