It has come to the attention of the University of the Free State (UFS) that false and inaccurate statements have been circulating on Twitter on 4 June 2020, claiming that its students were not equipped or supported to study remotely during the COVID-19 lockdown. The UFS believes that it is important to engage in dialogue to correct any misconceptions and inaccuracies that are at risk of being perpetuated.

Contrary to these reports, the UFS has invested much time and resources in the development and deployment of low-tech online and distance approaches to learning and teaching. Since March 2020, the university has undertaken extensive measures to support its students after classes were suspended and to ensure the continuation of the academic programme.

Statements on Twitter include a number of inaccuracies, which the university wants to correct:

• The Institutional Student Representative Council (ISRC) was not suspended by the Rector and Vice-Chancellor, Prof Francis Petersen. In fact, the university management regularly meets with the ISRC on matters of concern to them. Student representatives also serve on a number of institutional committees – both before and during the national lockdown.
• No deregistration of any students has taken place.
• Since the end of April 2020, structured and managed data was provided to students to obtain access to academic content as well as to the academic platforms for free. However, to access this free data, students need to download the GlobalProtect app – this was communicated numerously and explained to students.  The university’s ICT Services will provide video and technical guides to all students to assist them with downloading the app.
• As of June 2020, all allowances for which students qualify and which are approved by NSFAS, have been paid by the university.
• Although online learning provides a solution to continue with programme delivery, the university is deeply aware of the fact that access may be a barrier – especially during these extraordinary times.  To assist vulnerable students, a total of 3 500 laptops have been procured by the UFS, enabling the university to assist eligible students in accessing the online platforms, obtaining learning material, and engaging with lecturers. The university is in the process of distributing the laptops to students who qualify. The Department of Higher Education, Science and Innovation’s process to provide laptops to students is separate from the 3 500 laptops procured by the UFS.  

The UFS remains committed to supporting its students in response to COVID-19 and is looking forward to working as a community to prepare for the institution’s response to the new challenges of responsibly returning to campus life from June 2020 onward. As staff and students start returning to the institution in a phased approach this month, the UFS will continue to comply with all applicable governmental directives and health guidelines to ensure the safety, health, and well-being of its students and staff.

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.
