Thandi Mazibuko, with her presentation: LED there be light, was the overall institutional winner in the PhD category and the runner-up in the national competition of this year’s 3MT competition.

The Centre for Graduate Support (CGS) recently (11 October 2024) hosted the annual institutional Three-Minute Thesis Competition (3MT), which was followed by the national competition (25 October). This year, the nationals took place on the UFS Bloemfontein Campus. According to Tshepiso Mokoena, responsible for Research Capacity Development in CGS, the participating master’s and PhD students gave well-prepared presentations. The competition aims to equip postgraduate students with valuable communication and presentation skills.

She says that postgraduate students are encouraged to do research that will benefit the community. “To do this, students should be able to communicate and present their research to a non-specialist audience. The 3MT competition trains and equips them with skills that they will use in their community and workplace,” she noted.

Overall PhD winner

The overall winner in the PhD category of the UFS competition was Thandi Mazibuko with her presentation: LED there be light. Thandi was also announced as the first runner-up at the national competition.

Growing up in Qwaqwa, Thandi’s passion for mathematics and the natural sciences led her to pursue a BSc Physics degree at the UFS in 2013, followed by an honours at the UFS. She then completed her MSc at the University of the Western Cape and worked as a science engagement intern at iThemba LABS in Cape Town, which inspired her to start a YouTube channel with more than 4 800 subscribers, called Thandisayensi. On this channel she uploads Physical Sciences videos for learners in grades 10-12.

Thandi states that she loves learning and being in learning environments; in 2022, she registered for a PhD in Solid State Physics under the supervision of Prof Hendrik Swart and Prof David Motaung.

Her research focuses on synthesising a phosphor material capable of emitting red, green, and blue light, which, when combined, creates the perception of white light. Thandi compared the research process to cooking, explaining how the preparation of phosphors resembles food preparation. She believes that relatable language, analogies, and storytelling are important tools in science communication.

Thandi says that this competition was a valuable platform to improve her science communication skills. “It is an interesting challenge to explain your work in 180 seconds to an audience with different backgrounds,” she said, adding that she is excited to represent the UFS at the national competition.

The other winners

Each department hosts its own 3MT competition, and the winners and runners-up in both the master’s and PhD categories then represent their faculty in the institutional competition.

The master’s category winners from other faculties were:

Faculty of Economic and Management Sciences: Evodia Mohoanyane with Does SI/tutoring work and what about it works? Evodia was also the overall winner in the institutional competition in the master’s category.
The Humanities: Yonwaba Matshobotiyana with Of Speaking and Visibility: Black Women Poets' Voices in South Africa
Health Sciences: Viwe Fokazi with Establishing a novel 3D doxorubicin-resistant triple-negative breast cancer spheroid model

In the PhD category, the winners were:

Economic and Management Sciences: Chrizaan Grobbelaar with The use of gamification to enhance retirement preparedness of millennials
The Humanities: Sheree Pretorius with The Psychometric Properties of the Prison Adjustment Questionnaire (PAQ) among South African Male Incarcerated Offenders

With Thandi, first runner-up of the institutional competition, Chrizaan, participated in the national 3MT competition. Universities such as the Nelson Mandela University, UNISA, University of KwaZulu-Natal, University of the Western Cape, University of Johannesburg, and the Central University of Technology were also present.

UFS keeps the power on

2015-06-24

At a recent Emergency Power Indaba held on the Bloemfontein Campus, support structures at the university met to discuss the Business Continuity Intervention Plan to manage load shedding on the three campuses of the UFS.

Currently, 35 generators serving 55 of the buildings have already been installed as a back-up power supply on the three campuses of the university. According to Anton Calitz, Electrical Engineer at the UFS, the running cost to produce a kWh of electricity with a diesel generator amounts to approximately three times the cost at which the UFS buys electricity from Centlec.

Planned additional generators will attract in excess of R4 million in operating costs per year. For 2015, the UFS senior leadership approved R11 million, spread over the three campuses. Remaining requirements will be spread out over the next three years. University Estates is also looking at renewable energy sources.

On the Bloemfontein Campus, 26 generators serving forty-one buildings are in operation. On South Campus, two generators were installed at the new Education Building and at the ICT Server Room. Lecture halls, the Arena, the Administration Building, and the library will be added later in 2015. Eight generators serving 12 buildings are in operation on the Qwaqwa Campus. In 2015, the Humanities Building, Lecture Halls and the heat pump room will also be equipped with generators.

Most buildings will be supplied only with partial emergency power. In rare cases, entire buildings will be supplied because the cost of connecting is lower than re-wiring for partial demand. According to Nico Janse van Rensburg, Senior Director at University Estates, emergency power will be limited to lighting and power points only. No allowances will be made for air-conditioning.

“Most area lighting will also be connected to emergency power,” he said.

Where spare capacity is available on existing emergency power generators, requests received for additional connections will be added, where possible, within the guidelines. The following spaces will receive preference:
- Lecture halls with the lights, data projectors, and computers running
- Laboratories for practical academic work and sensitive research projects
- Academic research equipment that is sensitive to interruptions
- Buildings hosting regular events

According to Janse van Rensburg, all further needs will be investigated. Staff can forward all emergency power supply needs to Anton Calitz at calitzja@ufs.ac.za

Staff and students can also manage load shedding in the following ways:

1. Carry a small torch with you at all times, in case you are on a stairwell or other dark area when the lights go out. You can also use the flashlight app on your phone. Download it before any load shedding occurs. This can come in handy if the lights go out suddenly, and you cannot find a flashlight. Load-shedding after dark imposes even more pressure on our Campus Security staff. We can assist them with our vigilance and preparedness by carrying portable lights with us at all times and by assisting colleagues.
2. Candles pose a serious safety risk. Rather use battery- or solar-powered lights during load shedding.
3. Ensure that your vehicle always has fuel in the tank, because petrol stations cannot pump fuel during power outages.
4. Ensure that you have enough cash, because ATMs cannot operate without electricity.
5. The UFS Sasol Library has study venues available which students can use during load shedding.
6. When arranging events which are highly dependent on power supply, especially at night, organisers should consult the load-shedding schedule before determining dates and preferably also make back-up arrangements. If generators are a necessity, the financial impact should be taken into consideration.

The senior leadership also approved a list of buildings to be equipped with emergency power supplies.
