Choose excellence and moral uprightness graduates told
Dr Mantwa Lephoto graduated with a PhD in Physics. With her is Dr Kamohelo Tshabalala, her supervisor
It was joy all over at the Qwaqwa Campus of the University of the Free State (UFS) on Thursday 10 May 2018 when over 650 degrees, diplomas, and certificates were conferred on deserving academic achievers. Among the degrees conferred were seven PhDs and seven master’s degrees in the Faculty of Natural and Agricultural Sciences, and one doctorate in English in the Faculty of the Humanities.

Speaking to the proud graduates was the Honourable Acting Judge of the Supreme Court of Appeal, Mr Justice Tati Makgoka, and the Chancellor of the UFS, Dr Khotso Mokhele, who both congratulated the graduates on their success.

Immeasurable joy and pride
“In African culture, a child is a vessel of the community. And today you have not only brought immeasurable joy to your families, but also pride to your communities. You have also opened a window of opportunities and inspiration to the school learners in attendance here today,” said Justice Makgoka, referring to hundreds of invited school learners from as far as Rekgotsofetse Secondary School in Paul Roux.

“You have now assumed the roles of pathfinders among your people. You should therefore continue to share your talents, as well as moral and spiritual gifts, with your communities. Your qualifications today set you on a journey of lifelong learning and scholarship. It is so because your chosen fields of study are dynamic terrains constantly evolving and demanding a lifelong scholarship. We must also pay special tribute to those who contributed towards your success,” he said.

Support system is important
Dr Mokhele also encouraged graduates to thank their support systems that kept them going through the hard times of studying.

 “There are many other people who deserve to be thanked for your success and you must thank them accordingly,” he said, and asked graduates to stand up as a gesture of appreciation for their families and friends who filled up the Rolihlahla Mandela Hall.
He further edged all graduates to ‘choose excellence and moral uprightness’.

“Honest and excellent hard workers in our government are more likely to be constructively dismissed, as they prevent the stealing of state resources. It’s your responsibility to choose the kind of South Africa you want to live in and make it happen,” he said.
 
This year’s graduations also saw the first cohort of Bachelor of Administration students from the Faculty of Economic and Management Sciences graduating.

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.
