The UFS presented a number of special awards during the graduation ceremonies on its Bloemfontein Campus on 27 and 28 June 2019. 

Jannie de Villiers earns UFS Chancellor’s Medal

Chief Executive Officer of Grain SA and recipient of the 2019 Chancellor’s Medal, Jannie de Villiers, is a renowned leader in the agricultural and food sectors, nationwide and globally. He started his career as an economist for the South African Department of Agriculture in 1985, and dedicated more than 30 years of his knowledge, skills, and leadership to the agricultural sector, specifically in grain-industry development. 
Mr De Villiers is commended for a number of initiatives he has implemented to enrich people’s lives throughout his career. One of his many admirable achievements is equipping upcoming farmers with the necessary knowledge and practical skills to advance crops and establishing a sustainable livelihood for South African citizens in the process.

UFS Council honours Elzmarie Oosthuizen

Council Medal recipient, Elzmarie Oosthuizen, is the Director: Centre for Excellence in Teaching and Learning in the UFS Faculty of Natural and Agricultural Sciences (NAS). 
Oosthuizen’s experience and leadership in foundation and bridging programmes are exceptional. She has successfully initiated a programme to promote teaching and learning in Mathematics, Natural Sciences, Economics, and Agricultural subjects. Due to her active involvement in managing foundational and bridging programmes for students who do not meet the minimum requirements for mainstream higher-education degrees in NAS, the pass rate of the BSc bridging programme has increased from 34% to 83%. 

“This award inspires me to sustain my efforts and find extraordinary solutions for the challenging and complex scenarios that we are facing in higher education,” said Ms Oosthuizen. 

UFS June graduation Dean’s Medal recipients

Michelle Nöthling (Master of Arts in Africa Studies) in the Faculty of the Humanities and Megan Braithwaite (Master of Arts in Theology with specialisation in Bible Translation) in the Faculty of Theology and Religion were awarded Dean’s Medals on the morning of 28 June 2019. The Faculty of Education also honoured Deborah Lynn Fair, who achieved the best results for her master’s degree in Education with specialisation in Curriculum Studies, with a Dean’s Medal.

On the afternoon of 28 June, Teboho Mooko (Master of Medical Science with specialisation in Pharmacology) received the Dean’s Medal in the Faculty of Health Sciences. Tshanduko Mutandanyi (Master of Science majoring in Geohydrology) received the Dean’s Medal in the Faculty of Natural and Agricultural Sciences, as well as the Senate Medal for the best overall results in both under- and postgraduate qualifications in all the UFS faculties.

Dr Khotso Mokhele hosts Chancellor’s Dinner

Later that evening, the Chancellor of the UFS, Dr Khotso Mokhele, hosted the Chancellor’s Dinner in the Centenary Complex on the UFS Bloemfontein Campus, paying tribute to the outstanding achievements of the recipients of UFS honorary doctorates, Council and Chancellor’s medals, and doctorates. 

Among the honoured guests were the two honorary doctorate recipients, Dr Jerry Mofokeng wa Makhetha – world-renowned, respected television and theatre actor (DLitt Honoris Causa – Faculty of the Humanities), and Dr Bernie Fanaroff (DSc Honoris Causa – Faculty of Natural and Agricultural Sciences), who is the Co-chair of the BRICS (Brazil, Russia, India, China and South Africa) Working Group on Information and Communication Technologies and High-Performance Computing, and member of the Advisory Committee of the Breakthrough Listen project; Mr Jannie de Villiers; Ms Elzmarie Oosthuizen; the Rector and Vice-Chancellor of the UFS, Prof Francis Petersen; and Mr Willem Louw, Chairperson of the UFS Council.

Guests also enjoyed a musical performance by the Graduation Instrumental Ensemble under the direction of Anton Esterhuyse, accompanied by the vocal ensemble of Thabo Hlongwane, Jacobus Silwer, and Mario Lategan.

Scientists discover a water reservoir beneath the Free State
2009-12-09

Dr Holger Sommer

The Mantle Research Group Bloemfontein (MRGB), under the leadership of Dr Holger Sommer, a senior lecturer in the Department of Geology at the University of the Free State (UFS), has discovered an enormous water reservoir 160 km beneath the Free State.

This discovery, according to Dr Sommer, is the first of its kind in South Africa after he had previously made a similar finding in Colorado, USA.

However, this water cannot be used for human consumption. “It is not frozen water; it is not molecular water; it is not fresh water; it is not salty water; it is OH – water which is sitting in the crystal lattice,” he said.

He said the reservoir was comparable in size to Lake Victoria in Tanzania.
The researchers collected eclogites from the Roberts Victor (Rovic) Mine close to the town of Boshof, south-west of the Free State, for their study.

“The Rovic eclogites are rocks which represent former oceanic crust transported into the earth’s interior by complex plate tectonic processes about 2.0 billion years ago,” explained Dr Sommer.

“These rocks were finally carried back to the earth’s surface by volcanic (kimberlite) eruptions around 130 million years ago. Eclogitic rocks are therefore a window into the Earth’s interior.”

The question from the beginning for all MRGB scientists was: Is there water inside these rocks in such depth, and if so, where is it located?

To answer this question, Dr Sommer and his research fellows separated single mineral grains from eclogite samples and prepared about 100 micrometer (0,1 mm) thick rock sections. Afterwards, specific particle accelerator (Synchrotron) measurements were carried out in the city of Karlsruhe in Germany.

“And indeed, the MRGB found water inside the studied rocks from the Roberts Victor Mine,” he said. “The water was located in defect structures in crystal lattices and along boundaries between single mineral grains.”

“The occurrence of water at such depth would give first evidence that all water of the oceans could be stored five to ten times in the earth’s mantle.”
The study was conducted about a year ago.
