What needs to be done to POWER up South Africa?

2022 UFS Thought-leader webinar series: What needs to be done to POWER up South Africa?

The University of the Free State is pleased to present its third webinar titled, What needs to be done to POWER up South Africa, which is part of the 2022 Thought-Leader Webinar Series. As a public higher-education institution in South Africa with a responsibility to contribute to public discourse, the University of the Free State (UFS) will be presenting the webinar in collaboration with the Free State Literature Festival.  The aim of the webinar series is to discuss issues facing South Africa by engaging experts at the university and in South Africa.

Third webinar presented on 27 September 2022

South Africa’s ageing coal power plants are the cause of massive power outages on a regular basis. A dire need exists to diversify our energy mix and to consider more renewable energy. Renewable energy is regarded far cheaper than coal and the construction of coal power plants. South Africa is well positioned environmentally, with the best wind and solar potential on the entire African continent. Economic viability and benefits accompany the exploitation of renewable energy, which will provide much-needed stability in South Africa.

Date:   Tuesday 27 September 2022
Time:

Happy Khambule

Khambule is the former Greenpeace Africa senior political adviser on climate and energy. He studied law at the University of Johannesburg and was recognised by the British Council as a Global Changemaker and International Climate Champion in 2008 and 2010. In 2013, he was selected as one of the Mail & Guardian 200 Young South Africans. Khambule is an official party delegate to the United Nations Framework Convention on Climate Change and negotiates various issues, such as Paris Agreement implementation and response measures. He serves on the Paris Agreement Compliance Committee and is a non-executive director in Mansa Advisory. He serves on various boards, including the Earthlife Africa board and the CleanCity SA board, as an independent non-executive board chairperson.

Khambule is part of the inaugural President's Coordinating Commission on Climate Change (PCC) and is Business Unity South Africa's Head of Environment and Energy.

Louis Lagrange

Louis Lagrange is an agricultural engineer, who is specialised in project management, food process engineering, and energy engineering.  Lagrange is currently leading a team at the University of the Free State that has successfully established a new degree in Engineering Sciences.  The establishment was followed by new research in energy efficiency. Lagrange is also leading the establishment of a new full Engineering degree in Agricultural and Biosystems Engineering, specialising in energy engineering, food process engineering, and environmental biosystems engineering.

Prior to joining the UFS, Lagrange spent seven years at the University of KwaZulu-Natal as Senior Lecturer in the School of Bio-resources Engineering and Environmental Hydrology.  Here he focused on energy conversion through tractors, combine harvesters, and implements and developed the new food process engineering subjects.

Lagrange’s passion for education is also prevalent through the facilitation of strategic and scenario planning for groups and boards of directors, including the facilitation of certified energy manager, certified energy auditor, business efficiency professional, certified lighting efficiency professional, and fundamentals of energy management training over the past 12 years for Energy Cybernetics, the  Energy Training Foundation, and currently for the Institute of Energy Professionals Africa.  He also co-developed and is the trainer of the new Energy Audit Technician and Energy Performance Certificate training courses for South Africa.

Fight against Ebola virus requires more research
2014-10-22

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.
