Think three minutes is a long time
One slide and three minutes was all they had to present their research. Winners of the UFS Three-Minute Thesis competition in the Master’s category are from left: Nigel Masalla, Phuthi Samuel Masingi and Vuyisa Sigwela.

It may take three minutes to make noodles, but imagine presenting the 80 000-word research you spent months writing in just three minutes.

For master’s and PhD students participating in the annual institutional Three-Minute Thesis (3MT) competition at the University of the Free State (UFS), three minutes seem to go as fast as three seconds. Each participant is given three minutes to present the essence of their research, explaining the problem, methodology used, as well as the importance of their research using one slide.

A jubilant audience of staff members and students gathered at the Equitas Auditorium on the Bloemfontein Campus for the annual institutional 3MT competition. Interesting research topics across different fields of study, which the participants had spent months and even years researching, were presented in the master’s and PhD categories. After each presentation, a panel of judges and the audience had the chance to ask the participants questions on their research.

The competition is part of the initiative by the UFS Postgraduate School to showcase postgraduate research across disciplines, faculties, and universities. Participation in this competition helps to develop academic, presentation, and research communication skills to ensure that research students can effectively communicate their research in a language that even non-specialists can understand. 

It is the mandate of the school to “create an enabling environment for postgraduate students to excel in their pursuit of their academic quests”, according to Prof Witness Mudzi: Director of the UFS Postgraduate School. 

Winners at the event:

PhDs
• Third prize: Trudie Strauss - Babelish Confusion: Finding Statistical Structure in the Diversity of Languages (R3 000 cash prize)
• People’s choice: Nokuthula Tlalajoe - The transition of undergraduate first-year students into the MBChB programme: Social learning and integration

Master’s
• First prize: Phuthi Samuel Masingi   Physical demands of South African Football (R6 000 cash prize)
• Second prize and people’s choice: Nigel Masalla   “ Stealthing” – lifting the veil on non-consensual condom removal (R4 000 cash prize)
• Third prize: Vuyisa Sigwela - Extraction, characterisation and application of betalains from beetroot, cactus pear and amaranth (R2 000 cash prize)

The UFS will be represented by Trudie Strauss at the national 3MT competition on 26 October 2018. The national competition will take place on the UFS Bloemfontein Campus

Fracking in the Karoo has advantages and disadvantages

Fracking for shale gas in the Karoo was laid bare during a public lecture by Dr Danie Vermeulen, Director of the Institute for Groundwater Studies (IGS). He shared facts, figures and research with his audience. No “yes” or “no” vote was cast. The audience was left to decide for itself.

The exploitation of shale gas in the pristine Karoo has probably been one of the most debated issues in South Africa since 2011.
 
Dr Vermeulen’s lecture, “The shale gas story in the Karoo: both sides of the coin”, was the first in a series presented by the Faculty of Natural and Agricultural Science under the theme “Sustainability”. Dr Vermeulen is a trained geo-hydrologist and geologist. He has been involved in fracking in South Africa since the debate started. He went on a study tour to the USA in 2011 to learn more about fracking and he visited the USA to further his investigation in May 2012.
 
Some of the information he shared, includes:

- It is estimated that South Africa has the fifth-largest shale-gas reserves in the world, following on China, the USA, Argentina and Mexico.
- Flow-back water is stored in sealed tanks and not in flow-back dams.
- Fracturing will not contaminate the water in an area, as the drilling of the wells will go far deeper than the groundwater aquifers. Every well has four steel casings – one within the other – with the gaps between them sealed with cement.
- More than a million hydraulic fracturing simulations took place in the USA without compromising fresh groundwater. The surface activities can cause problems because that is where man-made and managerial operations could cause pollution.
- Water use for shale-gas exploration is lower than for other kinds of energy, but the fact that the Karoo is an arid region makes the use of groundwater a sensitive issue. Dr Vermeulen highlighted this aspect as his major concern regarding shale-gas exploration.
- The cost to develop is a quarter of the cost for an oil well in the Gulf of Mexico.
- Dolerite intrusions in the Karoo are an unresearched concern. Dolerite is unique to the South African situation. Dolerite intrusion temperatures exceed 900 °C.

He also addressed the shale-gas footprint, well decommissioning and site reclamation, radio activity in the shale and the low possibility of seismic events.
 
Dr Vermeulen said South Africa is a net importer of energy. About 90% of its power supply is coal-based. For continued economic growth, South Africa needs a stable energy supply. It is also forecast that energy demand in South Africa is growing faster than the average global demand.
 
Unknowns to be addressed in research and exploration are the gas reserves and gas needs of South Africa. Do we have enough water? What will be the visual and social impact? Who must do the exploration?
 
“Only exploration will give us these answers,” Dr Vermeulen said.
