Going global with the Umoja Buddy Programme

01 March 2019 | Story Valentino Ndaba

Student from the Umoja Buddy programme — Students from all corners of the globe forge lasting bonds through the Umoja Buddy Programme.

Let’s say you find yourself attending a university in a different country where you need to adjust to a new language, culture, environment, friends, lecturers, curriculum, and lifestyle. Sounds like a challenging leap of faith, right? However, the Umoja Buddy Programme (UBP) makes this transition a whole lot easier for international students.

If you were an international student at the University of the Free State’s (UFS) Bloemfontein Campus, you would be assigned a buddy who is familiar with student life and community. The Office for International Affairs in collaboration with Student Affairs designed this programme for all incoming exchange students to feel welcome and at home.

The UBP is part of the university’s endeavours to advance internationalisation at home, which was entrenched in the 2018-2022 UFS Internationalisation Strategy. Underlying is the idea to provide UFS students with international experiences on their home campus.

Integration at the heart of internationalisation

At the Bloemfontein Campus launch of the UBP on 14 February 2019, UFS Rector and Vice-Chancellor, Prof Francis Petersen, welcomed this year’s cohort of first-time international students and highlighted the importance of the UBP. “In essence, it aims to connect international and local students through meaningful lifelong friendships and to foster their academic, social and cultural integration at the UFS,” he said.

Prof Petersen strongly believes in the programme’s ability to facilitate “cross-fertilisation of ideas and intercultural exposure and learning”, which further enhances the quality of graduates produced by the institution.

A student is a student through other students

Lesotho-born Precious Lesupi volunteered as one of the 48 ambassadors to prevent others from experiencing the difficulties she did when she arrived at UFS. “I have been in a situation where you get to a place and you know nothing about the people there, especially the culture, and the way everything is done because you come from a totally different place, so it’s really hard to adjust.”

Lebohang Lesenyeho, who hails from Botshabelo in the Free State, expressed similar sentiments with fellow ambassador,Kweku Gavor. He said he “looks forward to “building a meaningful relationship.” Kweku who has Ghanaian origins believes that, “you cannot put a price on learning about another person and ways you react to certain situations.”

Umoja is a verb

True to the word umoja, which means “unity and the spirit of togetherness”, the programme has proved to bring together students from diverse backgrounds in the pursuit of academic excellence. The goal can be best achieved when complemented by a holistic social and cultural experience.

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.
