Koffie Yinkah — “I believe the Hesselbein Global Academy annual fellowship programme was vital for me as a potential public servant of South Africa to serve the people of this country in government one day.” – Kofi Yinkah

University of the Free State (UFS) third-year BAdmin student, Kofi Annan Yinkah, formed part of the Hesselbein Global Academy annual fellowship programme, hosted by the University of Pittsburgh in the United States of America (USA). Originally from the East Rand in Johannesburg, Kofi represented the UFS as one of the top-50 students who were selected out of 450 global applicants.

The Hesselbein Global Academy annual fellowship programme aims to connect young leaders from all over the world with well-equipped professionals who are leaders in the fields of business, government, and education. This programme was established for the purpose of cultivating and producing cadres who will become experienced ethical leaders, armed and qualified enough to address and solicit solutions for critical issues experienced by diverse societies throughout the world.

“The fellowship covered topics that have helped to broaden my critical thought processes and concerns about societal issues in our country and all over the world. It has also emphasised the importance of implementing change through effective governing-policy development and establishment,” Kofi says.

He describes his experience at the fellowship as “out of the ordinary,” and believes that it has had a progressive influence on his life. He explains how it has unlocked his mind through enlightened engagement with student leaders from various countries in the world, including Nigeria, England, Canada, Chile, Trinidad and Tobago, Vietnam, China, United States of America, and Ireland.

One of the most important tools he believes his experience has equipped him with, is understanding the significance of employing a solution-driven approach to various situations. He is confident that this will give him the necessary skills and knowledge to work effectively in teams.

Kofi explains that he found out about the fellowship programme via social media. He encourages UFS students to use online platforms to source information about opportunities that can offer them meaningful experiences for learning and growing.

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.
