Dear Student,

We know that many of you might be feeling anxious and uncertain about how the University of the Free State (UFS) is going to take learning and teaching forward during these extraordinary times. On Monday, 16 March 2020, the Rector and Vice-Chancellor, Prof Francis Petersen tasked the Teaching and Learning Management Group (TLMG) to develop alternative ways of taking learning and teaching forward. The TLMG, under the leadership of the Centre for Teaching and Learning (CTL), has been hard at work at developing a new approach.

Like most other universities, our best alternative to continue our learning and teaching is to move online. We are aware that moving online poses many challenges for our students since many of you do not have frequent and reliable access to the internet, or data when you are off-campus, or do not own the necessary devices to learn optimally. We are also aware that learning in a new way will mean that students and staff will need to create spaces for themselves to learn and work at home/off-campus. It does appear that we will be working online for an extended period of time, and we want to assure you that we will be here to support you in this journey as best we can.

The Keep calm, Teach On, and #UFSLearnOn campaigns are aimed at creating the best possible support for lecturers and students, respectively,
by adapting existing support and practices most suited to our new online environment. The new approach has the following components:

  1. Providing and developing support for lecturers to move learning and teaching online.
  2. Creating appropriate communication and support measures to help you learn as effectively as possible. The first of these is the Keep calm and #UFSLearnOn transition resource which will be shared with you through various platforms.
  3. Repositioning existing support systems to create a learning and teaching environment that considers the diverse needs and circumstances of our students.

As a start, here are the Keep calm and #UFSLearnOn dates on which resources will be released:

  • 25 March: This first edition will focus on helping you assess your current realities, and kick-start the planning for learning to continue.
  • 1 April: Release of Edition 2; this edition will be focused on getting connected and understanding how you will be learning when academic activities resume.
  • 8 April: Edition 3 to be released; the third edition will focus on the skills you need to be a successful student in the new environment.
  • 15 April: Edition 4 to be released; this edition will focus on helping you to stay and finish strong. This edition will also provide you with the university’s reassessment of the situation, which will be determined by the country's presidential lockdown situation.  
  • 17 April:            Academic activities will resume

We are very aware that for many of you access to devices, data, and networks is a challenge. As part of Universities South Africa (USAf), the UFS is negotiating to get our digital learning website zero-rated to minimise your costs. You will be receiving a survey link to provide us with information on the additional support you might need to connect and learn.

We know our students are resourceful and resilient to succeed in extraordinary circumstances. In the meantime, take some time to rest and recharge.

Best wishes,

Dr EL van Staden

From wheat protein to perfect pizza

Barend Wentzel, an alumnus of the University of the Free State’s Department of Plant Sciences, is passionate about plant breeding. 

He literally eats and lives wheat proteins. In 1989 he initiated a breeding programme on arum lilies. “This breeding programme is at an advanced stage,” he said. Besides reading, playing the piano and accordion, Barend, due to the nature of his research at the Agricultural Research Council, also experiments with different types of ciabatta recipes made from sour dough. “I usually make my own pizza on Saturday evenings,” he said.

He is working at the Agricultural Research Council – Small Grain (ARC-SG) at the Wheat Quality Laboratory where he established a Cereal Chemistry Laboratory.

Complexity of flour quality

He explains that the focus of his research is on wheat protein composition. “The research conducted for my PhD study explains the complexity of flour quality to a certain extent, and it further emphasises the influence of the environment and genetic composition on selected baking characteristics. 

“Wheat protein can be divided into different types of protein fractions. These protein fractions contribute differently to dough properties and baking quality and the expression is affected by different components in the environment, including locality, rainfall and temperature. 

“Protein content alone does, however, not explain the variation in baking quality parameters, such as mixing time, dough strength and extensibility, and loaf volume.

“Several methods can be applied to quantify the different protein fractions. I am using high-performance liquid-chromatography (HPLC). The procedure entails the separation of a wheat protein extract through a column with chromatographic packing material. The injected sample is pumped through the column (known as the stationary phase) with a solvent (known as the mobile phase). The specific procedure, size-exclusion high-performance liquid-chromatography (SE-HPLC), is also used by the university’s Department of Plant Breeding, as well as in several international Cereal Chemistry Laboratories,” said Barend.

Dough strength and to loaf volume
“One of the highlights from the study was the positive contribution of the albumin and globulin protein fractions to dough strength and to loaf volume. The findings were wheat cultivar specific and the growing environment influenced the expression. The contribution of these protein fractions was much larger than previously reported for South African wheat cultivars,” said Barend. 
“Previous reports indicated that these protein fractions had a non-specific contribution to the gluten network during dough formation. The findings from this PhD justify further research on albumins and globulin proteins.” 

The Cereal Chemistry Laboratory at ARC-SG is involved in postgraduate student training under Barend’s guidance. He serves as co-promoter for several MSc and PhD students. He is also a collaborator on an international project with the International Maize and Wheat Improvement Centre (CIMMYT) in Mexico. Barend is furthermore working on improving wheat quality for processing and health purposes as a member of the expert working group of the International Wheat Initiative.
