“We are trying to close the divide between Ghanaian and South African higher education institutions. Many Ghanaians look to UK and US universities as their first option. However, the same level of education, at a far less rate, is offered at South African higher education institutions – and the University of the Free State in particular.”

These were some of the sentiments shared by His Excellency Mr Charles Asuako Owiredu, High Commissioner of the Republic of Ghana to South Africa, during his recent visit to the University of the Free State.

The High Commissioner, accompanied by the Deputy High Commissioner and Head of Protocol, was hosted by Prof Francis Petersen. After a successful meeting, the students and academics from the Ghanaian community were also engaged. “The Vice-Chancellor was full of praise for the Ghanaian students and their performance at the UFS,” said the High Commissioner.

Prof Chitja Twala, Vice-Dean in the Faculty of the Humanities, highlighted the longstanding relationship that the UFS has with the University of Ghana. “We have a good relationship with the Department of History at the University of Ghana, and we are looking forward to collaboration with the institution,” added Prof Twala.

The High Commissioner felt strongly about cementing the relationships that already exist between the UFS and universities in Ghana and will lobby for education to be included in the master framework used as an operational document between the two countries. Faculty exchanges between the UFS and Ghanaian universities were also encouraged by the High Commissioner.

The High Commissioner encouraged Ghanaian students and academics at the UFS to suggest ways to deepen the relationship between the UFS and Ghanaian institutions.

Dr Prince Sarpong, Senior Lecturer in the School for Financial Planning Law at the UFS, proposed a collaboration between the UFS and Ghanaian institutions in the field of financial planning, whereby there could be an opportunity to reach out and expand the practice of financial planning to institutions in Ghana. The High Commissioner was eager to know more about financial planning and its location within law.

Ghanaian students who attended the meeting shared their experiences and perspectives about the UFS and indicated that an excellent relationship exists with project supervisors while pursuing their studies remotely.

According to Ghanaian students based on the UFS campuses, the UFS is doing great work by engaging students from Ghana in the UFS programme. However, students indicated that challenges were experienced with the South African Qualifications Authority (SAQA).

Dr Cornelius Hagenmeier, Director of the Office for International Affairs at the UFS, assured students that the aspect of SAQA is important and will be looked into, as it relates to the recruitment of students.

The High Commissioner also suggested that the Ghana Accreditation Board engage with SAQA.

 A UFS delegation will be visiting Ghana in October to explore the opportunities in agriculture, entrepreneurship, and the Business School.

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.
