University of Limpopo visits UFS Protection Services — Staff from the University of the Free State Department of Protection Services pictured with the delegation from the University of Limpopo during their benchmarking visit.

The University of the Free State Department of Protection Services hosted a delegation from the University of Limpopo on Friday, 13 May 2022 as part of benchmarking best protection service practices.

During the visit, discussions included the management of student protests, gender-based violence, fire emergency responses, and challenges experienced with the Campus Protection Society of Southern Africa.

The visit by the University of Limpopo follows similar benchmark visits by the Central University of Technology, Sol Plaatje University, and the University of Johannesburg.

Noko Masalesa, Senior Director: Protection Services, said: “The visit by the University of Limpopo was used to take them through our vision 2024, to show them some of the advanced CCTV cameras that the UFS has installed, the policies, and organisational structure. Part of that strategy is to enhance the university’s security technology in line with the best practices.”

Masalesa said: “The UFS has a good model to manage all the different functional areas of the Department of Protection Services, and most universities are impressed with the new CCTV cameras that we rolled out and the other advances made in the development of protection services over the past five years.”

To remain among the leaders in protection services within the higher education, the department also visited Stellenbosch University, the University of Cape Town, Cape Peninsula University of Technology, and the University of Nairobi and Kenyatta University – both in Kenya.

Mampuru Mampa, Director: Safety and Security at the University of Limpopo, said: “Like other institutions, the University of Limpopo is dealing with crimes affecting students on and off campus, as well as student protests. Fostering collaboration and benchmarking will assist our protection service departments to develop and implement a standardised approach to improve safety on our campuses.”

On lessons learnt during the benchmarking tour, Mampa said: “We have learnt about security system integration, investigation systems approach, off-campus security, and student protest management.”

Mampa believes “it is important for protection service departments across the higher education sector to develop standardised security measures to improve safety, and benchmarking assists in closing gaps in protection services”.

Nanotechnology breakthrough at UFS

2010-08-19

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.
