Jeremiah Hlahla, a UFS student completing his PhD in Botany at the University of Debrecen as part of an exchange initiative funded by the Erasmus+ Mobility Programme.
As part of an exchange initiative facilitated by the Erasmus+ Mobility Programme, Jeremiah Hlahla, a student at the University of the Free State (UFS), is nearing the completion of his PhD studies at the University of Debrecen in Hungary. Hlahla’s journey, which began in February 2024 and is set to conclude in July 2024, has been a remarkable learning opportunity. “As a first time-traveller to Europe, I have thoroughly enjoyed engaging with people from different countries and cultures,” he said.
The benefits of international collaboration
Hlahla is currently pursuing a PhD in Botany, focusing on plant stress physiology. “My current PhD project investigates the physiological, biochemical and morphological responses of vegetable-type soybean, or edamame, to combined drought and heat stress,’’ he explained. He considers the University of Debrecen the ideal institution to complete his research due to its extensive expertise and resources in similar projects. He noted that his colleagues at Debrecen conduct significant work on plant protection against biotic and abiotic stresses, including salt and drought stress, as well as proteins and amino acids in barley and other legumes.
Given the vast knowledge available on similar projects, Hlahla has found substantial engagement with his work at the University of Debrecen. “Upon arrival, I delivered an introductory lecture presenting my UFS project on the synergistic effects of combined drought and heat stress on the physiology and biochemistry of edamame. It was an engaging session as everyone could relate to my work and asked many questions,’’ he said.
Insights gained from the exchange
Hlahla has also gained valuable lessons that will assist him in his research career, including biotechnology and physiology tools. “I learned how to prepare samples and use high-performance liquid chromatography (HPLC) and reversed-phase ultra-high-performance liquid chromatography (UHPLC) to quantify proteins and amino acids,’’ he said. These techniques are beneficial not only for his current work but will also support future soybean research.
As his experience at the University of Debrecen nears its end, Hlahla reflects on the collaborations and friendships he has formed, which stand out as a significant highlight.
Mathematical problem-solving solutions found in African indigenous games
2015-04-02
A recent study by Dr Tshele Moloi, a Mathematics Education lecturer at the Qwaqwa Campus, revealed that games such as Diketo or Morabaraba enhance the understanding of abstract mathematical concepts in children. Diketo is a children’s game where 10 small stones or marbles and 1 ghoen or big stone are made available to each player. A small hole about 5cm deep is dug in which the small stones are placed for the players.
During this game of Diketo, learners can identify the variables involved – both dependent and independent. In round one of the game, it was found that the stones scooped out of the hole can be described by the pattern: f(n)= -n/2 + 21/2 , (where n denotes the throwing of the ghoen). Stones placed in the hole can be illustrated by the pattern: f(m)= -m/2 + 10, (where m denotes the throwing of the ghoen). There are many patterns that can be obtained when the players are in round two.
The patterns which emanate from rounds one, two, and three can be put on the Cartesian Plane, which can then demonstrate the linear functions.
