The 2020 programme around the 16 Days of Activism against Gender-Based Violence will be novel in that it will be run online. “For each person to register and log into the various programmes is a small step. But each such step makes a big difference by saying that the lives of survivors matter and by underscoring that gender-based violence will not be tolerated at the UFS,” says Prof Colin Chasi, Director of the Unit for Institutional Change and Social Justice (UICSJ) at the UFS.

Women and girl children have experienced increased violence in the time of the COVID-19 lockdown, states the UN Secretary General's report, Shared Responsibility, Global Solidarity: Responding to the socio-economic impacts of COVID-19. In South Africa, there have been reports of a scourge of rape in the post-school education and training sector. At the UFS, these developments have challenged the Gender Equity and Anti-Discrimination Office (GEADO) to come up with innovative online interventions.

In 2019, the University of the Free State (UFS) established the Unit for Institutional Change and Social Justice (formerly known as the Institute for Reconciliation and Social Justice, founded in 2009). The GEADO was launched on 8 April 2019 and was incorporated into the unit to run a cross-functional Sexual Assault Response Team (SART) and to organise programmes that combat gender-based violence and other forms of gender injustice.

“We have been able to offer our services with minimal disruption throughout the year,” says Geraldine Lengau, a Bloemfontein Campus-based GEADO officer.

“Most exciting for us is that we have taken the lockdown as an opportunity to expand the scope of ways in which we engage with students and communities,” notes Chelepe Mocwana, a GEADO officer on the South Campus. “GEADO has offered a number of online webinars and seminars, and the university has made telephonic services available that support, for example, the mental health of survivors of sexual violence.”

“On the Qwaqwa Campus, where we still have some problems with consistent access to data networks, we were pleased to see that our webinars have been well-subscribed to by students and staff members,” reports Siya Magayana, who is the GEADO officer on this campus.

“Each such step makes a big difference by saying that the
lives of survivors matter and by underscoring that
gender-based violence will not be tolerated at the UFS.”

Since 1991, activists around the world have annually coordinated activities around the 16 Days of Activism against Gender-Based Violence. The 16 days of activism begin on 25 November, the International Day for the Elimination of Violence against Women, and run until 10 December, which is International Human Rights Day. The start and end dates signify that the fight to eliminate violence against women advances human rights for all.

Activities to mark the 16 Days of Activism against Gender-Based Violence will be advertised on various UFS communication platforms.

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.
