KovsiesCare - Clean Up Read More
Tsietsi Ngobese, through the Wesolve4x Cleaning My Planet Campaign, motivated citizens to collectively fill over 23 000 refuse bags to date.
The mission: To collectively fill 20 million refuse bags every Saturday with the help of 20 million people who are cleaning their own communities and our planet for an hour. The message: My planet, my responsibility.

The mission and message that the Wesolve4x Cleaning My Planet Campaign wants to convey, is based on a simple premise: Get community members to donate one hour of their time to cleaning duties every Saturday for the next 20 years until 2039. At the same time provide a continuous educational programme about waste management to the general public and to schools in order to empower them to take responsibility.

Address trash blindness

Tsietsi Ngobese, Chief Executive Officer of this initiative and BSc Actuarial Science graduate, says he understands the transformative power of education and the role it plays in transforming diverse communities. Through outreach programmes in our community and schools, we are slowly eliminating generational trash blindness. We also tackle some of the social determinants of health by encouraging healthy living conditions within our communities through good waste management and recycling. 

It is important for Tsietsi to add value to society. He believes that the Wesolve4x Generation will transform the world for the better through education and empowering all citizens.

The campaign – officially endorsed by Miss Earth South Africa, Catherine Constantinides – was launched on the UFS Bloemfontein Campus as well as the Abram Hlope Primary School in Katlehong on 4 May 2019.

“We want to promote the benefits of a clean and healthy environment for future generations,” said Tsietsi. 

Since their inception, the group has collectively filled over 23 000 refuse bags with the help of active citizens. 

Challenge accepted

When former lecturer, Jan Blomerus, once challenged his Actuarial students to protect the environment in order to decrease the mortality rate (from natural disasters because of the effect of climate change), Tsietsi accepted the challenge. “By inspiring excellence and transforming lives, the UFS plays an important role; I started to believe that I can address societal challenges in the communities I am an integral part of,” he said.

When Tsietsi saw trash piling up everywhere and children playing at illegal dumping sites, he became concerned about the health risk to society. He believes the dumping area is contaminating the air and water around the dumping site. 

“I had to be part of the solution to start cleaning up, and most importantly, educating myself and others to continuously take responsibility for our own waste and change our thinking about littering. This is a generational issue and needs a generational approach to unlearn all habits of littering,” Tsietsi pointed out. 

As part of his vision, Tsietsi plans to reduce the waste taken to landfill sites and to increase that which is taken directly from households to recycling plants. He also wants to encourage people to find creative ways of converting what has previously been wasted into something useful. “This action can encourage individuals to generate an income from waste,” he said.

Take action

Tsietsi invites all members of the Mangaung community to get involved in the project. This is your opportunity to make a difference on Mandela Day. You can;
• provide sponsorship for educational content on effective waste management, economic opportunities, and health issues to the general public and to schools;
• provide refuse bags, plastic gloves or hand-washing soap (used by community members in every clean-up session);
• join in a collective effort to clean your community by meeting at designated schools or any designated community assembly point on a Saturday (contact 011 307 2005 or info@wesolve4x.com for more information).

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.
