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

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.
