The Kovsie ACT programme encourages the evolution of UFS students to form internationally competitive graduates who embody sustainable energy knowledge and skills to contribute to the development of the global environment.

Be a part of the evolution and livestream this year’s University of the Free State (UFS) Kovsie ACT Eco-vehicle race on 15 May 2021.

What’s in it for you? Get exposed to an informative but exciting event that will assess the technology and logic behind sustainable energy sources and how this will influence the future global society.

According to Karen Scheepers, Head of the University of the Free State (UFS) Kovsie Act office, the quest for sustainable resources remains one of the top-five challenges facing the global population of today. This challenge – together with issues pertaining to food insecurity, water, waste and toxins, and the widening gap between rich and poor – poses new questions to the kind of graduates that universities produce, she added.  She further highlighted the importance of innovative critical thinking that responds to day-to-day issues experienced by society in a global context.

Therefore, the UFS has initiated an eco-vehicle project to help students develop the necessary graduate attributes to specifically address issues of sustainable resources. The aim of the eco-vehicle project is to implement, within the context of a higher education institution, a new innovative skills development solution to the challenge of sustainable resources, and to evaluate the efficacy and impact of this programme in a rigorous way. 

Through this programme, senior undergraduate students worked together in teams through a mediated learning programme to build scale-model electric vehicles and mini solar charging stations – powered by solar energy (or batteries charged through solar energy).  This experience will steer them towards finding solutions and creating awareness around 21st century issues, and adapting to the development of technology and globalisation, essentially producing an interdisciplinary experience for UFS students.

Kovsie ACT eco-vehicle skills programme

According to the Kovsie ACT team, the eco-vehicle skills programme helps students understand how their decisions and actions affect the environment, and further implores them to build on their knowledge and skills in order to address and combat complex environmental issues, while taking sufficient action to maintain its healthy state and secure it for the future. 

The skills development programme culminates in a race-day event where sustainable energy skills are put to the test. 
A certificate endorsed by the UFS and donor partner merSETA will be issued to students who have participated and who have been successfully trained and developed in the eco-vehicle skills programme, giving them a head start to the working world.

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.
