EMS graduation
Jan Johannes van Niekerk and Pierré Ludwig Koekemoer

This year, two proud recipients of the Dean’s Medal were honoured during the 2020 UFS Virtual Graduation Ceremony. Jan Johannes van Niekerk received the award for the best results in respect of a Bachelor’s Degree in the Faculty of Economic and Management Sciences (Bachelor of Accounting), and Pierré Ludwig Koekemoer was awarded the medal for the student who achieved the best results in respect of a Bachelor Honours Degree in the Faculty of Economic and Management Sciences (Bachelor of Commerce Honours with specialisation in Marketing).

Jan Johannes van Niekerk

Prior to commencing his studies at the UFS, Van Niekerk attended Fichardt Park High School in Bloemfontein.  Van Niekerk describes his time thus far as a student in the School of Accountancy as “nothing less than special”.  He adds that “… the support from the lecturers is really great … every lecturer has always tried to help me to the best of their ability!”

His favourite subject is Financial Accounting, and his Financial Accounting lecturers inspired him to follow in their footsteps; accordingly, he became a Financial Accounting tutor in his second and third years of study.  “As academic staff, we have come to know Johan as a pleasant and well-mannered, diligent, and hardworking student who pays attention to detail,” says Prof Frans Prinsloo, Director: School of Accountancy.

Johan is completing his BAcc Honours studies this year and will commence his training contract with Enslins Auditors in 2021 to qualify as a chartered accountant (SA).

Pierré Ludwig Koekemoer
“Pierré Koekemoer is one of the most decent young men I’ve met in years.  Hardworking, diligent, and one of the most respectful and responsible people I know,” says Prof Brownhilder Neneh, Associate Professor in the Department of Business Management.

Pierre Koekemoer was identified as the Best Honours Student for 2019 in the School of Accountancy, as well as the student with the best Honours script.  Koekemoer excelled during his Honours year, and successfully managed his responsibilities as student assistant/marker; he was also part of the City Lodge Marketing project that took place during the second semester.  

The General Manager of the Fairview Hotel in Nairobi, Kenia, offered Koekemoer a short internship at the beginning of 2020, as he was impressed with his performance.  Koekemoer could not accept the job, as he had obtained permanent employment and did not want to lose the position. “This also speaks of his integrity, as he had already committed to the company,” comments Prof Neneh.

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.
