Prof Jeremy Smith
Prof Jeremy Smith, Adjunct Professor in the Department of Architecture, recently delivered his inaugural lecture on the UFS Bloemfontein Campus.

A few days after the annual Sophia Gray lecture, the Department of Architecture at the University of the Free State (UFS) hosted the inaugural lecture of Prof Jeremy Smith.

Prof Smith, the Design Director of Irving Smith Architects in New Zealand and an Adjunct Professor in the UFS Department of Architecture, is known for his innovative approach to architecture that emphasises sustainability and the relationship between buildings and their natural surroundings.

Earlier this year, he partnered with RTA Studio – an architectural firm based in Auckland, New Zealand – and won the prestigious Dubai International Best Practices Award for Sustainable Development in the category of the Most Beautiful, Innovative and Iconic Building with the entry: The ‘Scion Innovation Hub, Te Whare Nui O Tuteata.

A changing climate

Themed Being Finished is Finished, the lecture attracted a diverse audience of architects, industry stakeholders, academics, students, and the general public. Prof Vasu Reddy, Deputy Vice-Chancellor: Research and Internationalisation, welcomed Prof Smith and the attendees. He congratulated Prof Smith on this milestone, highlighting that a professor’s work often represents the beginning of much unfinished business. He noted that the UFS is proud to host such lectures, which celebrate and acknowledge excellence in research and practice.

Prof Paul Oberholster, Dean of the Faculty of Natural and Agricultural Sciences, introduced Prof Smith, praising his impressive career and the numerous national and international awards he has received.

Prof Smith’s lecture focused on the evolving relationship between architecture and the landscape, particularly in New Zealand, where only a quarter of the original forests remain. “We know our climate is changing. In New Zealand we massively made landscape; landscape is everything. Modernism has asked us to use the lawnmower,” he remarked.

He believes in the importance of architecture that adapts and evolves within its natural surroundings, rather than imposing new landscapes. He introduced the concept of ‘soft architecture’, which involves designing buildings that fit into the changing landscape. This approach allows for a sustainable relationship between architecture and nature, ensuring that buildings enhance rather than dominate their environment.

He illustrated this philosophy with a project, the ‘Bach with Two Roofs’ house, which was damaged by a cyclone in 2014. The storm altered the surrounding landscape, and rather than simply repairing the house, Prof Smith redesigned it in a flexible and adaptive manner that might accommodate environmental change. This project demonstrated how buildings can be refurnished to adapt to a shift in the landscape, ultimately coexisting with and responding to the natural world.

“From life in the forest, the landscape shifted – the sun was hotter, the wind was stronger. Our building has lost its fit to the landscape. Refurnishing it, we need to acknowledge that this time a new forest will grow. It will be a stronger forest – it will be indigenous and will grow in relation to the building. In this shifting landscape, it’s not the landscape that needs to be refurnished. It is the building.”

Doing more with less

Prof Smith also discussed two award-winning projects: the ‘Te Whare Nui O Tuteata’ project and the ‘Feather House’. Both projects are examples of his commitment to sustainability and adaptive design – doing more with less.

The ‘Te Whare Nui O Tuteata’ project, part of the New Zealand government’s SCION Timber Research Institute, uses a diagrid timber structure that reduces material usage and allows the building to integrate seamlessly with its forest surroundings. The building was designed with a neutral carbon count, and the timber used was locally sourced, reflecting the natural landscape.

Prof Smith described the building as an educational invitation to visitors to ‘walk in our forest’ and learn new and sustainable ways of resourcing and building with timber. “The building behaves like a forest – the closer you get the more is revealed. Light filtering through its timber framework is also much like sunlight through a forest canopy – enhancing the building’s connection to its surroundings.” 

In discussing the Feather House, Prof Smith highlighted the importance of designing spaces that can evolve with their inhabitants. “Design for the ‘there and then’ rather than for the ‘here and now’,” he said. “One cannot design a room for every occasion, but you can provide an invitation.” He advocates for creating architecture that anticipates future changes and adapts to evolving environments, ensuring that buildings remain relevant and functional over time. His design philosophy underscores connection rather than division of spaces and doing less rather than more to create adaptable and sustainable living environments. “Do not design the space based on whose shoes are in the shoe rack,” he commented.

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.
