Braille Signage
Big on Braille: Members of the Kovsie community who are living with visual impairments can now access directions through the new braille system.
The University of the Free State (UFS) commemorate World Sight Day, which is celebrated annually on the second Thursday of October. The day has been set aside and aimed at drawing attention to blindness and vision. This was originally initiated by the #SightFirstCampaign of the Lions Club International Foundation in 2000. 
The university aims to contribute to the development and social justice of all students through the production of globally competitive graduates. Thus, the development and implementation of co-curricular programmes, activities, services, and mutual infrastructure will allow for humanising daily lived experiences among students, which are essential for universal access, student academic success, social behaviour, engagement, and an inclusive institutional culture.

With this in mind, the university rolled out a capital project that included the construction of tactile pathways with braille indicators on the pathways, designed to support and caution pedestrians who are blind or visually impaired. The indicators are universally accessible, because it includes Braille and text. The text then gives indications to new students who are also struggling to find their way around campus.

A UFS Bachelor of Social Sciences student who dreams of becoming a social worker, Tshegofatso Nkatlholang, who was born partially blind, but is now completely blind is motivated by the prospect of living a life where she has the ability to help the less fortunate. Her opinion of the construction and implementation of the new tactile pathways on the UFS Bloemfontein Campus is that they are extremely helpful. She went on to say, “That is my road, and I am grateful for a university that strives to operate an inclusive infrastructural environment where I don’t feel sidelined.”
Kovsie student Keamogetswe Mbele was born partially blind with very low vision, eventually losing her eyesight. She explained that she had no knowledge of the newly built braille indicators on the tactile pathways, but that she felt appreciative of the university’s initiative to constitute an inclusive academic and infrastructural environment for all students on campus. Motivated by her personal goals of independence and financial freedom, ‘Kamo’, as her peers refer to her, is determined to live a prosperous academic life throughout the course of her studies at the UFS.

According to Mookgo Moloi, a Kovsie student who was not born blind but gradually lost her sight at the age of 15, said, “Life on campus is very caring”. She reflected on the opportunities, as well as the technical and emotional support that the Center for Universal Access and Disability Support (CUADS) has provided her, which has made her academic career a lot easier, and more advantageous for her to graduate. 
CUADS further strives to facilitate, create opportunities, and enhance students’ understanding of multiple intersections and ways of being that are consistent with human rights and the principles of social justice.

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.
