Ronet Vrey.

She is affectionately called ‘Tannie Ronet’ by the dozens of students coming her way, and Faculty of Education librarian Ronet Vrey would not have it any other way. While Vrey loves to remain behind the scenes, her passion for students makes her a big hit with every student crossing her path at the University of the Free State Library and Information Services on the Bloemfontein Campus. 

Vrey has been a librarian for as long as she can remember; a path she says was inspired by her educator mother. But instead of standing in front of a class, she gets to invest in students' academic journeys by being a helping hand in times of need. She is a UFS alumna, having graduated in 1988 with a degree in Library and Information Sciences, specialising in Education, Library Services, and Technology. 

"I was interested in library information services because back then, we were exploring the use of computers and moving in the direction of technology. Little did we know about digitisation and curation that would follow."

In 2005, she started working as librarian for the Faculty of the Humanities, before working jointly for the Faculties of the Humanities and Education. Since 2011, she has focused solely on the Faculty of Education, serving as the link between the library and the faculty. "I am supposed to focus only on students from the first year to honours level, but because of the relationships built there, many students often choose to stay with me. When they come to me for help, I don't say no," she says.

Information literacy a lifelong skill

Vrey shares the love for her job with her fellow librarians from other faculties. In 2019, the group presented a paper on embedded librarianship at the International Conference on Information Literacy (ICIL). She said they are in the process of having their paper published. "We want to be embedded in faculties in order to make students at the UFS information literate. If we can teach students information literacy skills to help themselves, we will have lifelong learners who can develop all the time, and you would have established a community of lifelong learners," she said.

One student who has benefited from Vrey's dedication and passion for students, is Dr Norma Lehasa, who obtained her PhD in 2019 after a seven-year journey due to ill health.

Vrey known as beacon of hope

Lehasa met Vrey in 2016, and says she owes her success to the likes of Vrey. Lehasa said each year when students graduate, it is people like Vrey who are supporting them behind the scenes to reach their goals. 

"My wonderful librarian, Ronet, made me focus and never give up. She used to go the extra mile for me, even teaching me how to use the resources to search for literature myself. The outcome of me being a Doctor of Philosophy today is because of people like Ronet. People like her need to be recognised for the good work that they do," Lehasa said.
Lehasa's PhD topic was: An Adult Learning Perspective on Professional Development in the Human Resources Department of the Free State Premier.

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.
