South Campus: Social Responsibility Project team with Free State Department of Health nurses during the lunch of the campus’ COVID-19 pop-up vaccination site.

On Monday 27 September 2021, the University of the Free State, Provincial Department of Health and Department of Education launched a pop-up vaccination site at the South Campus bringing much-needed services closer to communities in the fight to end the COVID-19 pandemic.

Thandeka Mosholi, Head of Social Responsibility, Enterprise and Community Engagement, South Campus says, “We are next to the Mangaung community and bringing these services we encourage not only UFS staff and students but the surrounding communities to vaccinate for COVID-19. The institution and stakeholders are saying it is everyone’s responsibility for their health.”

She says, “If vaccination is recommended and we are told that it is safe, we encourage everyone including the youth to preserve our health and vaccinate.”

Representing the Department of Health, Papi Mokhele, Professional Pharmacist, says, “The initiative is aimed at reaching out to as many people to be vaccinated.”

He says, “At the moment the facility administers only the Pfizer vaccination and, as recommended by the National Government, we want to reach herd immunity – about 70% of the population – so that businesses, sporting facilities and many others can open and get our life back to normal.”

Other facilities the Department of Health has recently opened include the SABC Hoffman Square, Majakathata Taxi Rank, MUCCPP Health Centre in Phelindaba, Puma Garage in Bergman and Mangaung Outdoor Centre.

On partnering with the UFS, Mokhele says, “The COVID-19 vaccines have been put through clinical processes and quality assurance tests. They have also been approved by the South African Medicine Control Council and we call on the UFS community, especially students, to register and vaccinate.”

Coretha van den Heever, Teacher Trainer in the Social Responsibility Project, was recently vaccinated for the pandemic and says, “Let us protect ourselves and other people and not be the spreaders of the virus.”

She says, “People must make use of the facility; the UFS and government have brought the solution closer so that communities will not have to spend a lot of money travelling to get help.”

The vaccination centre will operate from Monday to Friday from 9:00 to 16:00.

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.
