WomenOfKovsies Prof LenkaBula foresees transformation at UFS
Vice-Rector: Institutional Change, Student Affairs, and Community Engagement, Prof Puleng LenkaBula, takes the lead in transforming Student Experiences at the UFS.

“It’s important to think about transformation in ways that are responsive to the challenges which students have raised,” said Prof Puleng LenkaBula. She thinks of transformation as constitutive of deliberative processes, actions, reflections, writings, and literary expressions aimed as a response to the ecological, economic, political, and social context and questions which undergird the learning, research, and engagement of UFS students, staff, and stakeholders.

Prof LenkaBula is Vice-Rector: Institutional Change, Student Affairs, and Community Engagement at the University of the Free State (UFS). 

Committed to knowledge production, novelty, and the advancement of socio-economic development in South Africa, Prof LenkaBula assumes position as work-stream leader for Student Experience in the Integrated Transformation Plan (ITP). The plan aims to identify areas of transformation that the UFS marks to revolutionise and implement in its pursuit of delivering quality graduates who will be able to contest in a global realm of competitors.

Importance of revolutionising Student Experience at the UFS

“My job is to ensure that students flourish academically and are cultivated holistically as human beings who bring embodied knowledge and experiences which will enable them to succeed in life,” detailed Prof LenkaBula. 

She also contributes towards change in the Engaged Scholarship as well as the Names, Symbols and Spaces work streams of the ITP. Prof LenkaBula has been deemed powerful in her ability to traverse disciplinary parameters, research, stakeholder cultivation, and development.

“It is important to navigate symbols and spaces as a co-aspect of Student Experience to enrich the diversity of know-hows at the UFS and map a university that will represent a value-system that prioritises inclusivity and diversity,” urged Prof LenkaBula with reference to the significance of her role in the implementation of the ITP.

Ensuring that UFS graduates are locally adept, knowledgeable, active, and globally competitive in imperative areas of interest, highlights the general importance of the ITP for Prof LenkaBula.

The Vice-Rector underlined that the UFS has had historical challenges within its existence which have demonstrated a need for change that promotes dignity for all and respect for the diversity of its people, in an effort to secure social cohesion.

“Open dialogue and participation are mechanisms that the university needs to make use of to engage the past in order to create constructive directions for the future,” said Prof LenkaBula.

She concluded by stating that the UFS is a key global resource, as we live in a state of economic globalisation. “Knowledge is an essential imperative in knowledge-economies that breed skilled labour, and the ability to think critically in order to formulate ideas that will change the world”, said Prof LenkaBula.

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.
