First Lady Visit
At a gathering with the First Lady and UFS management were, from the left: Prof Prakash Naidoo, Vice-Rector: Operations; Prof Maléne Campbell; Chacha; Dr Tshepo Motsepe, First Lady of South Africa; Prof Petersen; Prof Puleng Lenka-Bula; Vice-Rector: Institutional Change, Student Affairs, and Community Engagement; and Prof Danie Vermeulen, Dean of the Faculty of Natural and Agricultural Sciences.

“I am from a very small town called Marquard. I am a granny’s boy – who was a domestic worker – and can speak fluent Afrikaans. I am fearless and I understand my calling for greatness. I stand and advocate for social justice and I am not scared to challenge any form of injustice. I hate people who abuse power and I am no friend of mediocrity. I speak my mind.”

This and much more describes Thapelo Chacha, a graduate in the Department of Urban and Regional Planning, who received his Honours degree in Spatial Planning at the recent April graduation ceremonies of the University of the Free State (UFS). 

The First Lady

He is also the student who brought Dr Tshepo Motsepe, the First Lady of South Africa to Kovsies. 

Chacha tells his story: “I met the First Lady some years back through Dr Vuyelwa Manzana, who was my mother’s doctor at the time – after dropping out of university due to a financial crisis. I was handed over to the lawyers, with a debt that accrued over three years. I knocked at every door you can think of – with no luck. One day I got a call from a lady who introduced herself as Mme Tshepo, asking me to go to university. I laughed, because I knew my debt was too big to allow me to study again. She insisted, and when I arrived at the UFS, my outstanding debt had been paid and I was able to register. The same Mme Tshepo called to assure me that she will pay for my tuition, meals, books, and accommodation. I did not even know that she was the wife of Mr Cyril Ramaphosa, who would later become the Deputy President and now the President of the country.”

“Mme Tshepo sponsored me from her own pocket until I became part of the Cyril Ramaphosa Education Trust (CRET).”

“She personally texted and called me about my graduation information so she could attend. You can imagine the excitement and the shock. Although I have met the First Lady many times, it will be the first time that I will introduce her to my family. She is taking me and my family – my mother and my grandmother – to lunch after the ceremony. I see that as a favour of God upon my life.”

Prof Francis Petersen, UFS Rector and Vice-Chancellor at a meeting with Dr Motsepe and Chacha said: “Access to university is crucial. However, we would also like our students to exit with a qualification. This is how a bursary like this one from CRET helps. We would like to exit students that contribute to the economy.”

Making a difference

Chacha is now doing his master’s in Urban and Regional Planning. “I am so looking forward to registering with the South African Council for Planners (SACPLAN) as a professional town planner at the end of my master’s degree within a few months. 

“I see myself joining a town planning division anywhere in South Africa, dedicated to changing the living conditions of ordinary citizens. Spatial planning speaks to the heart of land use and ensures that the land is used and occupied in a manner that is beneficial to everyone who needs it,” Chacha said. 

He believes town planning has been largely influenced by politics, thus forcing town planners to move away from serving the needs of the ordinary citizen. Chacha would like to see the injustices of the past, especially with regard to townships, being addressed. “This is why my dissertation is about township infrastructure and the contribution it makes towards township economy.”

“I would like to see a South Africa that is centred on the well-being of its citizens. The older generation has fought the brutality of apartheid; our battle as the youth is to be academically equipped to fight and win the land battle,” he said.

Kovsie encounters

For Chacha, his studies in Urban and Regional Planning was very tough. But the support he received from his lecturers was immeasurable. “Prof Maléne Campbell, Head of the UFS Department of Urban and Regional Planning has the most competent team. This is the best department on campus, with no racial issues or unpleasant vibes. I just love the space.”

“The UFS has taught me resilience, hard work, the importance of networking, and the knowledge that you need to be radical when it comes to your future,” Chacha concluded.

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.
