Vegetable tunnels
Two vegetable tunnels were recently established on the UFS Bloemfontein Campus to contribute to the fight against food insecurity.

Food insecurity is a problem on university campuses worldwide. The three campuses of the University of the Free State (UFS) are not exempt from this plight. Research findings indicate that more than 64% of students at the university go through periods of hunger.

Annelize Visagie, , from the Division of Student Affairs who is heading the Food Environment Office at the UFS, confirms that food insecurity at higher education institutions is not a new phenomenon.

In a study with first-year students as focus, Visagie found that academic performance declines and coping mechanisms increase as the severity of food insecurity increases.

“Students use different coping mechanisms, with an alarming percentage of students (40,6%) using fasting as an excuse to friends for not having food, 60% of students skipping meals because they do not have enough money, and 43,2% of students being too embarrassed to ask for help.”

Visagie states that various factors contribute to this alarming scenario, with the main reason being that the majority of students come from impoverished economic and social circumstances. This suggests that although students receive NSFAS funding or any other bursary, it is not a guarantee that they are food secure.

Focus on student wellbeing
Aligning with the UFS strategic goal of improving student success and wellbeing, UFS staff is working hard to implement initiatives and obtain sponsorships and food donations to ensure that students do not go hungry.

Members of the university’s Food Environment Project, Drs Johan van Niekerk and JW Swanepoel from the Centre for Sustainable Agriculture, Rural Development and Extension (CENSARDE), and Karen Scheepers from the Division of Student Affairs who is heading KovsieAct partnered to move the existing vegetable tunnels on the UFS experimental farm to the Bloemfontein Campus.

The construction of the tunnels and boxes was financed by Tiger Brands. Professor Michael Rudolph and Dr Evans Muchesa who are involved with the Siyakhana Food Gardens, assisted with the training of students and consultation throughout the project.

The two tunnels (30 m x 10 m each) are covered with netting, and two water tanks with pumps are fitted to provide the necessary irrigation.

Vegetables add value
Dr Swanepoel explains: “In each tunnel there are 20 raised wooden boxes. Each residence received one box where they planted one type of vegetable crop, including Swiss chard, cabbage, carrots, beet, kale, and broccoli.”

Residence Committee members from all on- and off-campus student communities in civic and social-responsibility portfolios, as well as civic and social-responsibility student associations, received the necessary training to plant vegetables.

The vegetables were planted in mid-February and the first harvest is expected around mid-April.

This initiative, which will help students in the near future to keep the hunger pangs at bay in a healthy way, adds to the existing No Student Hungry programme. Visagie says it is important for the university to assist students in making healthy choices and to educate them on decisions to secure nutritional food for themselves.

In addition, the university also received food parcels from Rise Against Hunger, together with donations from organisations such as Gift of the Givers – providing 200 food parcels to students on the Qwaqwa Campus, and the recent donation from Tiger Brands – providing 500 food parcels to students.

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.
