Think three minutes is a long time
One slide and three minutes was all they had to present their research.

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

UFS venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
