Prestigious academic medals awarded to outstanding UFS students

During the recent June graduation ceremonies at the University of the Free State (UFS), the winter chill subsided with some heart-warming academic achievements in postgraduate studies. Four students were awarded a Dean’s medal for the best master’s degree in their respective faculties, and the overall best achiever received a Senate’s medal. The faculties in the limelight were Education, the Humanities, Theology and Religion, and Natural and Agricultural Sciences boasting both a Dean’s and Senate’s medal. 

Biblical analysis and interpretation
Interestingly, the Bible served as subject matter for two master’s degrees from two different faculties – each receiving a Dean’s medal. HJ Prinsloo, under the guidance of his study leader, Prof Francois Tolmie from the Faculty of Theology and Religion, took a closer look at Paul’s letter to the Galatians. “I hope that my studies made me become a critical-thinking theologian who can make a contribution to the interpretation of Paul’s letters,” Prinsloo said. He would like to continue his research by doing a PhD. “My academic interest is the rhetoric of the undisputed Pauline letters in the New Testament.” He gave all the glory and honour to God for his achievement. 

A few blocks down in the Faculty of the Humanities, Sophia Lynn Pitcher sunk her teeth into the Masoretic cantillation accents of the Hebrew Bible a complex medieval notation for recording the chanting and recitation of the Old Testament text. “Her prosodic model is ground-breaking in that it provides the key to unlocking the intonational patterns of the Old Testament, which will have significant implications for biblical interpretation and exegesis for Bible translators and students,” said her study leader, Prof Jacobus Naude, and co-study leader, Prof Cynthia Miller-Naude. “The study of the Masoretic accents has been largely ignored by Hebrew and biblical scholars,” they elaborated. “Her research demonstrates that it is possible to understand the Old Testament in light of the sounds of its sentences, as well as the words on the written page.”

Class time
In her striking polka-dot, ankle-high laced-up sneakers, Lesley Jean Wright not only earned her master’s degree with specialisation in Psychology of Education, but also the Dean’s Medal in the Faculty of Education. Although she has always been an achiever, it was the first time that she received an award of this calibre at university level. “My research is part of the way in which I have chosen to change the world in which I live,” she explains her passion and drive. “The best part of my studies was learning in so much more depth about an area of which I knew very little in academic terms.” She completed her research titled, A Collaborative Inquiry Towards Understanding the Experiences of ‘Out’ Lesbian and Gay Teachers in Gauteng Schools, under the guidance of her supervisor and mentor, Prof Dennis Francis from Stellenbosch University

Maths minds

The Faculty of Natural and Agricultural Sciences had a proud moment when two of their students received sought-after awards. “Modelling real-world problems with mathematical tools is perhaps one of the most difficult exercises in research,” said Prof Abdon Atangana about the research of his student, Mashudu Mathobo, who received a Dean’s medal. Prof Atangana commended Mathobo’s passion, devotion, and dedication to his studies. “He was at my door every morning to discuss the previous night’s work.” Mathobo revised Theis’s mathematical model portraying the movement of groundwater to find a more accurate solution. He came up with an exact groundwater flow equation for a confined aquifer, taking all Theis’s assumptions into account, as well as high-order terms that Theis removed from his equation. 

Also using mathematics to solve problems of a different kind, was Actuarial Science student and Senate’s medal recipient, Enrico Scheltema. Currently in his honours year, he received this noteworthy award for his undergraduate studies. He is driven by his love for problem-solving and is looking forward to entering the workplace next year. “It is an interesting feeling to be awarded for something you did some time ago,” Scheltema said. While he is yet to fully appreciate the magnificence of his achievement, the faculty and university salutes the young man for his brilliance and dedication.

Several industries in South Africa are currently producing hundreds of thousands of tons of carbon dioxide a year, which are released directly into the air. A typical family sedan doing around 10 000 km per year, is annually releasing more than one ton of carbon dioxide into the atmosphere.

The Inorganic Chemistry Research Group in the Department of Chemistry at the University of the Free State (UFS), in collaboration with the University of Zurich in Switzerland, has focused in recent years on using carbon dioxide – which is regarded as a harmful and global warming gas – in a meaningful way. 

According to Prof André Roodt, Head of Inorganic Chemistry at the UFS, the Department of Chemistry has for the past five decades been researching natural products that could be extracted from plants. These products are manufactured by plants through photosynthesis, in other words the utilisation of sunlight and carbon dioxide, nitrogen, and other nutrients from the soil.

Caffeine and chlorophyll 
“The Inorganic group is systematically researching the utilisation of carbon dioxide. Carbon dioxide is absorbed by plants through chlorophyll and used to make interesting and valuable compounds and sugars, which in turn could be used for the production of important new medicines,” says Prof Roodt.

Caffeine, a major energy enhancer, is also manufactured through photosynthesis in plants. It is commonly found in tea and coffee, but also (artificially added) in energy drinks. Because caffeine is a stimulant of the central nervous system and reduces fatigue and drowsiness, some people prefer decaffeinated coffee when enjoying this hot drink late at night. 

Removing caffeine from coffee could be expensive and time-consuming, but also environmentally unfriendly, because it involves the use of harmful and flammable liquids. Some of the Inorganic Group’s research focus areas include the use of carbon dioxide for the extraction of compounds, such as caffeine from plants. 

“Therefore, the research could lead to the availability of more decaffeinated coffee products. Although decaffeinated coffee is currently aromatic, we want to investigate further to ensure better quality flavours,” says Prof Roodt.

Another research aspect the team is focusing on is the use of carbon dioxide to extract chlorophyll from plants which have medicinal properties themselves. Chemical suppliers sell chlorophyll at R3 000 a gram. “In the process of investigating chlorophyll, our group discovered simpler techniques to comfortably extract larger quantities from green vegetables and other plants,” says Prof Roodt.

Medicines
In addition, the Inorganic Research Group is also looking to use carbon dioxide as a building block for more valuable compounds. Some of these compounds will be used in the Inorganic Group’s research focus on radiopharmaceutical products for the identification and possibly even the treatment of diseases such as certain cancers, tuberculosis, and malaria.
