UPDATE: Situation on the Bloemfontein Campus, 23 February 2022

23 February 2022 | Story Lacea Loader

On the morning of 23 February 2022, some of the entrance gates to the Bloemfontein Campus were blocked by groups of protesting students. The gates were cleared by members of Protection Services and traffic could continue to enter and exit the campus.

Sporadic disruption of classes occurred during the course of the day, with several students being arrested by the South African Police Service (SAPS) for disruption of classes, which is contravention of the interdict.

The disruptive behaviour stems from students’ unhappiness with the response to the memorandum handed to the university management by the Bloemfontein Campus Central Student Representative Council (CSRC) on 21 February 2022. Also on 21 February, a memorandum was handed to the management of the Qwaqwa Campus by the campus’ CSRC. The Qwaqwa Campus was temporarily closed yesterday, following violent protest action this week; the date for the reopening of the campus will be communicated in due course.

Today’s disruptive behaviour demonstrated by the group of students on the Bloemfontein Campus is condemned and will not be tolerated.

During this week and on numerous occasions before that, the university management has been in extensive engagements with the CSRCs on both campuses; concessions were made where possible, as was demanded in the two memoranda. However, the responses given, and the concessions made by the university were not accepted by the student leadership of the Bloemfontein Campus CSCR in particular, with more demands being made.

READ: Response to the Bloemfontein Memorandum of Demands Dated 21 February 2022

Concessions from the beginning of 2022:

To ensure that students register successfully for the 2022 academic year, the UFS has granted a number of financial concessions to students since the beginning of the year. The financial support given was specifically intended to fast-track the registration process of students with outstanding debt, and those awaiting confirmation of funding from the National Student Financial Aid Scheme (NSFAS).

These concessions included:

Allowing students who have previously registered for foundation programmes and those who have continued with mainstream programmes to register without the prerequisite of a first payment. The provision was granted to students who applied with the N+ rule and whose respective foundation programmes are included in the Department of Higher Education and Training-funded list.
Permitting students with outstanding debt of up to R25 000 and who await NSFAS funding to register provisionally.
The university also allowed conditional registration for first-time entering students, giving those who have applied for NSFAS funding until 28 February 2022 to finalise their registration. First-time entering students, both residential and non-residential, could register conditionally, provided that they pay an amount of R500.

Demands in the two memoranda received from the CSRCs on the Bloemfontein and Qwaqwa Campuses included matters such as private accommodation; emergency accommodation; catch-up plans for students who have not yet registered; a registration threshold increase to R30 000; NSFAS allowances; and the extension of registration for international students without study permits. The Bloemfontein Campus CSRC did not accept the university’s responses to the memorandum.

The university management will continue engaging with the SRC.

Safety measures in place:

The situation on the Bloemfontein Campus is closely monitored. Protection Services is on high alert and continues to work closely with the SAPS to ensure stability on the campus.

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.

Figure 1. Yeast cells exposed to over-used cooking oil. Wart like protuberances/ outgrowths (WP) is clearly visible on the surfaces of the elongated yeast 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.
