Qwaqwa Campus welcomes international students

Integration. Diversity. Inclusivity. Academic excellence.

These words featured prominently during the welcoming event for international students on the Qwaqwa Campus of the University of the Free State. The event was organised by the International Student Council (ISC), in collaboration with the Office for International Affairs (OIA).

“The presence of international students is bound to enrich diversity on campus, as it converges vast experiences of the world within one space. It further promotes social integration between South African students and those from the region and beyond,” said Teboho Manchu, Acting Campus Principal.

Opportunity to connect
Teboho further stated that international students provide a critical opportunity for all students to connect, irrespective of their origin.

“Immerse yourselves in the local culture and most importantly, go out there in the communities and connect with the ordinary people,” he added.

In encouraging international students to fully participate in the student programmes on campus, the Acting Campus Vice-Principal: Support Services and Director: Student Affairs, Temba Hlasho, said that Student Affairs supports all students, irrespective of their choice of study or origin.
“To show that we as Student Affairs care, we are going to institute a process in which the SRC Constitution will be reviewed to include international students. This will enable all students to use the positive environment to further thrive in their chosen careers. Participate in all the student activities and leave a mark. Exploit the nature of this campus. Take advantage of its relatively small size and warmth,” he said.

SRC Constitution review
In his response on behalf of the students, the SRC President, Masopha Hlalele, concurred with the campus management that the time was right to review the SRC Constitution to include international students as well as postgraduate students.

“We commit to fast-tracking this process so that the amended constitution can be adopted by the UFS Council in June 2018. In the meantime, continue making your mark on every inch of this campus,” he said.

International students in the audience came from the Southern African Development Community (SADC) region, Cameroon, Ethiopia, Kenya, Nigeria, Ghana, and India.

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.
