Rapport Regstreeks

Since the national elections of 2014 five years ago, several issues have occurred that could have an impact on the upcoming elections. A panel consisting of Dr Ina Gouws from the Department of Governance and Political Transformation, Dr Sethulego Matebesi from the Department of Sociology – both at the University of the Free State (UFS), and Dr Ebrahim Fakir from Governance Institutions and Processes at the Electoral Institute for Sustainable Democracy in Africa, talked about these and other issues.

The panel discussion, facilitated by Waldimar Pelser, editor of Rapport, took place at the UFS on 8 March 2019. Rapport Regstreeks is presented by kykNET and Rapport.

Three factors that can handicap ruling party

“Does the ruling party have anything to be worried about?” Pelser asked, getting straight to the point. “Yes. The ruling party has a lot to be worried about. The reason for this is that voter participation has declined; secondly, there is definitely a management problem which resulted in a credibility crisis in the government; and lastly, the ANC is trying to keep people together who do not believe in the same issues,” Dr Fakir was the first to reply.

The issues mentioned by Dr Fakir have been a problem before. “Since 2016 there has been a lot of division within the ANC,” Dr Gouws said. “These divisions can have a huge impact on the outcome of the election. The divisions were exposed even more by the Nenegate situation, and the ANC could no longer manage it."

The fact that the ANC lost control over four of the major metros in the 2016 local elections must be worrying to them.

Zondo Commission and opposition parties

The Zondo Commission, with its appalling revelations has uncovered the magnitude of state capture and the shocking testimonies that have emerged, could possibly hamper the ANC in the elections. “Political parties have supporters, regardless of internal problems. Loyal party members will still vote for their parties,” said Dr Matebesi. “The promise of RDP houses before an election is the bread and butter of many voters; therefore, they will vote ANC again.”

With the rise of the Economic Freedom Fighters (EFF), the support base of the ANC has also dwindled. “If there is one party with a colonial mentality, it is the EFF. They are undermining democracy, thrive on divisions in society and exploit them,” said Dr Fakir. “They jump in on many issues for their own gain,” Dr Gouws added.

As for the Democratic Alliance (DA), Dr Gouws said its governance is ‘fantastic’ compared to the ANC, although not always 100%. “Problems were however highlighted – it is not 100% and I think they should attend to the problems.”

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
