A story of hope, courage, resilience, and working your way to the top. Dilahlwane Mohono started working as a cleaner at the UFS in 1992. Today, she is a Senior Faculty Officer in the Faculty of Natural and Agricultural Sciences and holds two honours degrees.

Fuelled by her deep pain due to falling pregnant during her matric year, as well as the desire to one day hold a qualification, Dilahlwane Mohono – Senior Faculty Officer in the Faculty of Natural and Agricultural Sciences – says her story is her favourite, as it is a story of hope, courage, resilience, and working your way to the top.

Because of her pregnancy, Mohono did not complete Grade 12 in 1990. She got married immediately thereafter. In 1992, she began working as a cleaner for a company that was insourced to provide meals on the University of the Free State Qwaqwa Campus. She says this experience often left her with mixed feelings, as it hurt to see her peers studying further, but this is also what ultimately motivated her to complete her matric. “Graduation ceremonies were the most painful events for me. This eventually pushed me to turn to ABET to complete my matric in 1994. From there, I was determined to start my academic journey, so I registered with Stanford Business College for a Secretariat and Computer Skills Diploma. It was a six-month course, but I graduated in the end. That graduation inspired me. It motivated me to study further. Juggling work and studying became challenging, because I was a young mother and wife, but I had to attend classes after work.”

The joy of education

In 2000, she registered for a Higher Diploma with Unisa, and at the same time took up a new position in the library on campus. At the time, it was still called the University of the North Qwaqwa Campus. She recalls this as the beginning of her upward trajectory in life. “The joy of education and seeing how far I have come made me realise how much potential I have, so in 2003 I registered for a BA Sociology and English degree at the UFS, and thereafter went on to do my BA Honours in Sociology.”

She took up a new position as Assistant Officer in the Faculty of Education. Wishing to be relevant to her new faculty, Mohono completed a Postgraduate Certificate in Education (PGCE), and thereafter a second honours degree in Curriculum Studies. “I felt like I was flowing. My colleagues helped me out and I wanted to ensure that I was the best in everything, because I did not want to disappoint them. What always encouraged me, were my children. I separated from my husband in 2003, so I found myself raising my kids single-handedly, and I needed to show them that we could all make it, and life would still go on.”

In 2018, the Faculty of Natural and Agricultural Sciences advertised a senior position. Mohono says she took a chance and applied because she wanted more growth. “I am now a Senior Faculty Officer. I was privileged to be afforded an opportunity to work for the university, so I always thought – how can I work in an academic higher learning environment and not use the opportunity to study and pursue an education.”

Is there a woman who inspires you and who you would like to celebrate this Women’s Month, and why?
It has to be my late mother. She was a very hardworking woman, but she passed on very early, in her early 40s. She worked in the same dining hall I started in, and a lot of the women I worked with then worked with her too. They took me under their wings and motivated me to continue chasing my dreams. Some were not even educated themselves, but they motivated me. I drew a lot of inspiration from them.

What advice would you give to the 15-year-old you?

She must take pride in being a woman, know who she is, and know that she must be brave and confident, and run with education as the key to her success. If it wasn’t for education, I shudder to think where I could’ve been. When I look back and see what I have achieved, being able to rise from all that while single-handedly raising my children, it makes me feel very strongly about myself. I am a very powerful woman.

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.
