Michelle Marais and Wian Visser
The UFS winners of the Old Mutual Agricultural Student of the Year Competition are Michelle Marais and Wian Visser.

The University of the Free State (UFS) once again produced winners at this year’s Old Mutual Agricultural Student of the Year competition. Michelle Marais, honours student in the UFS Department of Agricultural Economics, and Wian Visser, final-year BScAgric Agronomy student, were top scorers in the Agricultural Economics and Crop Production sections respectively. 

Learning from the best

Apart from the opportunity to compete in their field of study, Michelle and Wian also benefited from the expertise of industry leaders in agricultural economics, animal science, and crop production. They had the opportunity to learn from Dr John Purchase (Agbiz), Dr Dirk Strydom (Grain SA), and Gerhard Schutte (Red Meat Producers’ Organisation), who acted as industry partners and judges during the competition. 

Michelle always had a particular interest in the development of emerging farmers and plans on doing her master’s degree in Agricultural Economics, focusing on emerging wool farmers. “Beyond that, I hope to get an opportunity to work finding solutions to some of the problems facing development in agriculture,” she said. 

Wian also plans on completing his master’s. “Thereafter, I would like to enter the workforce and help the current and future producers to farm better in a changing environment. The ideal would be to remain in a research-oriented position while working full time,” he said. 

Participating with the UFS in this competition, were Stellenbosch University (producing the overall winner in the Animal Science section, Pieter Theron), the University of Fort Hare, North-West University, and the University of Pretoria. As with last year’s competition, the students first had to compete in an initial round at their respective universities, after which eleven finalists went through to the final round held during the ALFA expo at the Afridome in Parys. 

Rewarded for hard work

The winners were announced during a gala dinner at the expo. Besides a green blazer and R1 000 prize money, Michelle and Wian also received an Old Mutual investment portfolio worth R5 000. They furthermore gained exposure on Grootplaas and RSG Landbou and in Plaas Media’s magazines Veeplaas, Stockfarm, and FarmBiz.

According to Dr Frikkie Maré, Academic Head of the Department of Agricultural Economics (UFS), the Old Mutual Agricultural Student of the Year competition provides the ideal opportunity for universities to showcase the quality of their Agricultural students, and thus the quality of their teaching and research practices. 

He said: “In the two years that the competition was hosted, the UFS managed to win the Agricultural Economics and Animal Science divisions in 2018, and the Agricultural Economics and Plant Production divisions in 2019.  We have thus been able to win all three categories over the two years, which can only serve as an indication that the UFS is indeed one of the top Agricultural Science universities in the country.”

Preparing for the workplace

Wian and Michelle both agree that they have received more than just the exposure and funding. 

In her own words, Michelle described the value added: “This competition challenged me to become more aware of current events within the politics, policy, and economic development in the country and the influence on our specific industry. The opportunity to present my findings and opinions on current issues in agriculture to several industry leaders, challenged me to combine the theoretical knowledge gathered in my four years of study with my practical experiences. Applying it to real-world problems and finding possible solutions helped me to realise that I could not have asked for better preparation in the workplace.”

According to Wian, the competition presented him with the opportunity to develop his networking skills and a chance to express his opinion in a professional environment. “It broadened my perception on agriculture by exposing me to different entities in the agricultural community. I also saw different methods and approaches in the sector that I am not necessarily familiar with,” he said. 

Wian believes the UFS has one of the best agricultural faculties in the country and that staff put a lot of effort into preparing students for the world of work. “The Department of Agronomy encourages critical thinking, an essential skill in an ever-changing work environment,” said Wian. He added: “Assessments are not only theoretical, but practical. These practical skills are related to the work required in a work environment. The department also exposes its students to companies, resources, and contacts that are helpful for networking when one enters the workforce.”

According to Michelle, the Department of Agricultural Economics also play their part in preparing students for the job market. “Our assignments always challenged us to contact people in the industry, to do industry research, and to plan practically,” she said. 

Old Mutual has been involved as the name sponsor of this Plaas Media competition since 2018 and has played an active role in promoting and developing the competition.

Fight against Ebola virus requires more research
2014-10-22

Dr Abdon Atangana, a postdoctoral researcher in the Institute for Groundwater Studies at the University of the Free State (UFS), wrote an article related to the Ebola virus: Modelling the Ebola haemorrhagic fever with the beta-derivative: Deathly infection disease in West African countries.

“The filoviruses belong to a virus family named filoviridae. This virus can cause unembellished haemorrhagic fever in humans and nonhuman monkeys. In literature, only two members of this virus family have been mentioned, namely the Marburg virus and the Ebola virus. However, so far only five species of the Ebola virus have been identified, including:  Ivory Coast, Sudan, Zaire, Reston and Bundibugyo.

“Among these families, the Ebola virus is the only member of the Zaire Ebola virus species and also the most dangerous, being responsible for the largest number of outbreaks.

“Ebola is an unusual, but fatal virus that causes bleeding inside and outside the body. As the virus spreads through the body, it damages the immune system and organs. Ultimately, it causes the blood-clotting levels in cells to drop. This leads to severe, uncontrollable bleeding.

Since all physical problems can be modelled via mathematical equation, Dr Atangana aimed in his research (the paper was published in BioMed Research International with impact factor 2.701) to analyse the spread of this deadly disease using mathematical equations. We shall propose a model underpinning the spread of this disease in a given Sub-Saharan African country,” he said.

The mathematical equations are used to predict the future behaviour of the disease, especially the spread of the disease among the targeted population. These mathematical equations are called differential equation and are only using the concept of rate of change over time.

However, there is several definitions for derivative, and the choice of the derivative used for such a model is very important, because the more accurate the model, the better results will be obtained.  The classical derivative describes the change of rate, but it is an approximation of the real velocity of the object under study. The beta derivative is the modification of the classical derivative that takes into account the time scale and also has a new parameter that can be considered as the fractional order.  

“I have used the beta derivative to model the spread of the fatal disease called Ebola, which has killed many people in the West African countries, including Nigeria, Sierra Leone, Guinea and Liberia, since December 2013,” he said.

The constructed mathematical equations were called Atangana’s Beta Ebola System of Equations (ABESE). “We did the investigation of the stable endemic points and presented the Eigen-Values using the Jacobian method. The homotopy decomposition method was used to solve the resulted system of equations. The convergence of the method was presented and some numerical simulations were done for different values of beta.

“The simulations showed that our model is more realistic for all betas less than 0.5.  The model revealed that, if there were no recovery precaution for a given population in a West African country, the entire population of that country would all die in a very short period of time, even if the total number of the infected population is very small.  In simple terms, the prediction revealed a fast spread of the virus among the targeted population. These results can be used to educate and inform people about the rapid spread of the deadly disease,” he said.

The spread of Ebola among people only occurs through direct contact with the blood or body fluids of a person after symptoms have developed. Body fluid that may contain the Ebola virus includes saliva, mucus, vomit, faeces, sweat, tears, breast milk, urine and semen. Entry points include the nose, mouth, eyes, open wounds, cuts and abrasions. Note should be taken that contact with objects contaminated by the virus, particularly needles and syringes, may also transmit the infection.

“Based on the predictions in this paper, we are calling on more research regarding this disease; in particular, we are calling on researchers to pay attention to finding an efficient cure or more effective prevention, to reduce the risk of contamination,” Dr Atangana said.
