The Centre for Health Systems Research and Development (CHSR&D) at the University of the Free State (UFS) recently donated 500 masks to Rekopane Primary School in Botshabelo. This initiative was part of its pledge to donate 100 cloth masks to a previously disadvantaged primary school for every 1 000 of the first 5 000 completed questionnaires that formed part of a study survey examining people’s understanding of information about COVID-19 vaccines. The results of the study will be shared with stakeholders who are responsible for providing information about COVID-19 vaccinations.

It is known that a large number of people globally and in South Africa prefer not to be vaccinated. “There are many reasons for this, and we would like to find out where people are getting information about the COVID-19 vaccination, and whether they are able to understand this information, so that they can make an informed choice about getting vaccinated. We did this by asking people about their own health and COVID-19, where they have heard about the vaccine, if they understood this information, and whether they have had/would have the vaccine or not, as well as the reasons for this,” said Prof Michelle Engelbrecht, Director of CHSR&D. 

While following guidelines such as wearing masks, sanitising hands, and social distancing are important to prevent the spread of COVID-19, a large percentage of the population will need to be vaccinated if we want to control the pandemic in the long term and prevent hospitalisation and severe illness. 

All persons in South Africa aged 18 and older were invited to complete an online survey regarding their perceptions of COVID-19 vaccines. The survey, which was available in the seven most spoken languages in the country, was advertised on social media platforms such as Facebook and Twitter, and on the Moya app.  The survey was open from 1 to 31 September 2021, and the CHSR&D received 10 554 completed questionnaires.  No data was required to complete the survey.

The Department of Basic Education partners decided on the school that would benefit, and the study provided an opportunity to support Bloemshelter, a UFS flagship programme. Alfi Moolman of the Directorate: Community Engagement said that “NGOs are really struggling to make ends meet, and we are delighted that Bloemshelter could provide the masks as one of their income-generating projects.  So many lives are touched for the good. The university is indeed a caring organisation.”

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.
