Postgraduate School welcomes Qwaqwa students

Postgraduate Student Council and SRC member, Teboho Mofokeng, says one degree is not enough.

Postgraduate studies play a crucial and critical role in the missions of our universities. They also contribute to the key and central mandate of the university – knowledge production, the dissemination, and application thereof.

The Campus Principal, Dr Martin Mandew, expressed this view during a welcoming function for postgraduate students on the Qwaqwa Campus. “Our Postgraduate School is the gateway that enables entry into higher degrees and qualifications. It is an extremely valuable resource and support reference point which is at the disposal of the students,” he said.

Postgraduate research and national development

Dr Mandew added that postgraduate research plays a very important role in national development, as it develops systematic investigation skills among young graduates for the purpose of making a contribution to what he termed ‘the national system of innovation’. “It also ensures that the country is competitive and enables the generation of knowledge that is responsive to societal needs, among others,” he said.

“Doing postgraduate studies is not easy,” he added. “Challenges that postgraduate students have to contend with, include funding and financial problems; lack of equipment; inadequate library facilities; access to research materials, and many more,” Dr Mandew said.

Support broadens knowledge and skills

In detailing the services offered by the Postgraduate School, the Director, Prof Witness Mudzi, assured students that they would experience an enabling environment to excel in the pursuit of their academic quests. “We will provide additional support to that provided by facilities and departments in the form of workshops, courses, and other presentations, which will equip the students with the requisite skills for successful completion of their postgraduate education.”

“The workshops and courses we offer are aimed at broadening your knowledge of research processes and methods. This would then positively influence throughput, publications, and the quality of research produced,” Prof Mudzi said to a packed venue.

Speaking on behalf of the SRC and the Postgraduate Student Council, Chairperson Teboho Mofokeng said that the event was held at a time when final-year students were asking themselves if it was worth continuing with postgraduate studies. “Do not take the decision to continue with your postgraduate studies lightly,” he said. “We work in a knowledge economy where specialised skills have significant commercial value. This means that in today’s competitive job market, it is often not enough to have only one degree,” said Mofokeng, a beneficiary of the school’s Mentorship Programme and master’s student specialising in Parasitology.

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.
