“Welcome to the South Campus of the University of the Free State!” Addressing a packed Madiba Arena, Prof Francis Petersen, Rector and Vice-Chancellor of the UFS, said he was happy to see not only first-year students, but also parents and guardians, student leadership, and support staff from both the Bloemfontein and South Campuses.

 “I would like to congratulate each of our first-year students for making the decision to come to Kovsies to further your studies here. But I would also like to thank you for making this choice,” he continued.

Prof Petersen further emphasised that the students’ experience and success as individuals are important to the UFS as an institution; therefore, academic and support staff are on hand to guide them through their journey to becoming well-rounded individuals. “We will surely take care of you,” said Prof Petersen. He also reassured parents and guardians that their loved ones would be well looked after.

The Rector also focused attention on the role of student-leadership structures, such as the newly-formed Institutional Student Representative Council (ISRC) and South Campus SRC, members of which were present in the audience. He thanked them for playing a key role in the student constituency, highlighting their support and guidance to help first-years cultivate a sense of belonging at the UFS.

Turning back to first-year students, Prof Petersen stated that they have the unique opportunity to study on a campus specifically focused on developing their full potential, a campus where they can realise their dreams. “Your arrival on the campus marks a new chapter in your life. This chapter is slightly different, as you are the author thereof. The previous chapters in your life were largely written by others—your parents, guardians, families, teachers, and others. You will now be the main author in the next chapter of your unique story.”

“At Kovsies, we believe in developing students in their totality as human beings, not just the academic side. May your time with us equip you to make a success of your life after university!”

Prof Petersen’s Message to First-year Students
  1. Take responsibility for your academic programme.
    • Keep your focus. Study and study hard. You will reap the rewards and see the advantages of making success in your studies a top priority.
    • Make sure that you have enough time for your studies; balance your social life and your time set aside to study.
  2. Realise and remember that you are not alone.
    • If you find things difficult, seek help.
    • Our Department of Student Counselling and Development has trained staff and tailor-made programmes that can assist you.
    • Look after your mental health—and look after each other’s mental health.
  3. Make the most of your time at Kovsies.
    • Join one or more of the student organisations; why not try something new?
  4. Embrace difference and diversity.
    • Get to know students who are different from you.
    • You will lose valuable opportunities to grow if you only associate with your own all the time. It is important to get to know students who are different from you. It could be someone from a different part of the country, or from another country, a different ethnicity, a different religion, someone who has different views from yours, or who has different interests and perspectives.

Fight against Ebola virus requires more research

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.
