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.

Research on cactus pear grabs attention of food, cosmetic and medical industry

The dedicated research and development programme at the UFS on spineless cactus pear (Opuntia ficus-indica) – also known as prickly pear – has grown steadily in both vision and dimension during the past 15 years. Formal cactus pear research at the UFS started with the formation of the Prickly Pear Working Group (PPWG) in June 2002. It has since gone from strength to strength with several MSc dissertations and a PhD thesis as well as popular and scientific publications flowing from this initiative.

According to Prof Wijnand Swart from the Department of Plant Sciences, the UFS is today recognised as a leading institution in the world conducting multi-disciplinary research on spineless cactus pear.

Cactus pear for animal feed

Increasing demands on already scarce water resources in South Africa require alternative sources of animal feed – specifically crops that are more efficient users of water. One alternative with the potential for widespread production is spineless cactus pear. It is 1.14 x more efficient in its use of water than Old man saltbush, 2.8 x more efficient than wheat, 3.75 x more efficient than lucerne and 7.5 x more efficient than rangeland vegetation.

“Studies on the use of sun-dried cactus pear cladodes suggest that it has the potential to provide some 25% of the basic feed resources required by South Africa’s commercial ruminant feed manufacturing sector,” says Prof HO de Waal of the Department of Animal, Wildlife and Grassland Sciences at the UFS.

Until recently, research has focused extensively on the use of cactus pear as drought fodder. However, this is now beginning to shift, with growing interest in the intensive production of spineless cactus pear for other types of animal feed. One example is the spineless cactus pear fruit, produced seasonal, yielding large quantities of fruit in a relatively short period of a few months in summer. Unless kept in cold storage, the fruit cannot be stored for a long period. Therefore, a procedure was developed to combine large volumes of mashed cactus pear fruit with dry hay and straw and preserve it for longer periods as high moisture livestock feed, kuilmoes – a high water content livestock feed similar to silage.

Cactus pear for human consumption

“In addition to its use as a livestock feed, cactus pear is increasingly being cultivated for human consumption. Although the plant can be consumed fresh as a juice or vegetable, significant value can be added through processing. This potential is considerable: the plant can be pickled; preserved as a jam or marmalade; or dried and milled to produce baking flour. It can also serve as a replacement of egg and fat in mayonnaise,” said Dr Maryna de Wit from the Department of Microbial, Biochemical and Food Biotechnology.

The extraction of mucilage from fresh cladodes can form a gelling, emulsifier, and fat-replacing agent commonly found in food products such as mayonnaise and candy. During an information session to the media Dr De Wit and her team conducted a food demonstration to showcase the use of the cladodes in a juice, chicken stir-fry, biscuits and a salad.

The extrusion of cactus pear seed oil provides a further lucrative niche product to the array of uses. These include high-value organic oil for the cosmetic sector, such as soap, hair gel and sun screens.

The cladodes and the fruit also have medicinal uses. It has anti-viral, anti-inflammatory, pain killing and anti-diabetic agents. It is also high in fibre and can lower cholesterol. The fruit also prevents proliferation of cells and suppresses tumour growth and can even help to reduce a hangover.

In South Africa the outdated perception of cactus pears as thorny, alien invaders, is rapidly disappearing. Instead, farmers now recognise that cactus pear can play a vital role as a high yielding, water-efficient, multi-use crop, said Prof de Waal and the members of the Cactus Pear Team.
