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.
How to interpret Centlec’s load shedding
2008-01-31
Everyone in South Africa is affected by power failures (load shedding). Centlec took certain measures to manage the situation. These measures are explained:
Time slots
See the following table for an indication of times when load shedding might be applied to specific areas: http://www.centlec.co.za/power_shed/PDF/time_slots.pdf
Groups
The city was divided into six groups. This document clearly indicates which area in the city resorts under which group: http://www.centlec.co.za/power_shed/PDF/groups.pdf
According to the document, the university resorts under group 4. In the table with time slots it is the grey area.
Stages
Eskom developed three stages for load shedding. (See stage table at the bottom of the page http://www.centlec.co.za/power_shed/PDF/time_slots.pdf)
- Stage 1: Less load shedding is applied in stage 1. E.g. the UFS resorts in group 4 and on a Monday, according to stage 1, the power will not be switched off during 12:00 and 14:30 (this time slot is not highlighted in orange).
- Stage 2: More load shedding is applied in stage 2. Load shedding will be applied during stage 2 between 12:00 and 14:30 on a Monday at the UFS.
- Stage 3: All time slots are highlighted in orange, which indicates that power will be switched off for the whole duration of stage 3.
Example
Today, Tuesday, load shedding was scheduled to take place from 10:00 to 12:00 at the UFS. Currently, according to Centlec’s web site, stage 1 is active. This time slot is not marked in stage 1, therefore load shedding is not applied. Centlec gives also additional information; “No load shedding in progress.”
Keep in mind that if an area is at risk it does not automatically imply that the power will be switched off. It all depends on the request from Eskom at that particular moment whether the actual shedding is required.
