Postgraduate Student Council and SRC member, Teboho Mofokeng, says one degree is not enough.
Postgraduate studies play a crucial and critical role in the missions of our universities. They also contribute to the key and central mandate of the university – knowledge production, the dissemination, and application thereof.

The Campus Principal, Dr Martin Mandew, expressed this view during a welcoming function for postgraduate students on the Qwaqwa Campus. “Our Postgraduate School is the gateway that enables entry into higher degrees and qualifications. It is an extremely valuable resource and support reference point which is at the disposal of the students,” he said.

Postgraduate research and national development

Dr Mandew added that postgraduate research plays a very important role in national development, as it develops systematic investigation skills among young graduates for the purpose of making a contribution to what he termed ‘the national system of innovation’. “It also ensures that the country is competitive and enables the generation of knowledge that is responsive to societal needs, among others,” he said.

“Doing postgraduate studies is not easy,” he added. “Challenges that postgraduate students have to contend with, include funding and financial problems; lack of equipment; inadequate library facilities; access to research materials, and many more,” Dr Mandew said.

Support broadens knowledge and skills

In detailing the services offered by the Postgraduate School, the Director, Prof Witness Mudzi, assured students that they would experience an enabling environment to excel in the pursuit of their academic quests. “We will provide additional support to that provided by facilities and departments in the form of workshops, courses, and other presentations, which will equip the students with the requisite skills for successful completion of their postgraduate education.”

“The workshops and courses we offer are aimed at broadening your knowledge of research processes and methods. This would then positively influence throughput, publications, and the quality of research produced,” Prof Mudzi said to a packed venue.

Speaking on behalf of the SRC and the Postgraduate Student Council, Chairperson Teboho Mofokeng said that the event was held at a time when final-year students were asking themselves if it was worth continuing with postgraduate studies. “Do not take the decision to continue with your postgraduate studies lightly,” he said. “We work in a knowledge economy where specialised skills have significant commercial value. This means that in today’s competitive job market, it is often not enough to have only one degree,” said Mofokeng, a beneficiary of the school’s Mentorship Programme and master’s student specialising in Parasitology.

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.
