Researchers from the University of the Free State (UFS) and the Central University of Technology (CUT) have recently learned that their research projects will be funded, with one research project even getting double the amount of funding requested. 

The research project of Dr Doors Fonternel, an MMed student working under Dr Edwin Turton in the Department of Anaesthesiology at the UFS, and Prof Ihar Yadroitsau (Igor Yadroitsev), Research Chair in Medical Product Development through Additive Manufacturing and the Faculty of Engineering, Built Environment and Information Technology at CUT, titled 3D Printed laryngoscope for endotracheal intubation, received R400 000 in funding. The project only requested half the amount, but in granting the funding, the evaluation committee was of the opinion that due to the relevance of the research and the long-term sustainability of the project, funding should be adjusted to R400 000.  

Another research project receiving R400 000 in funding, is a project by Dr Alice Brink, Senior Lecturer in the Department of Chemistry at the UFS, and Dr Tshepiso J Makhafola, Assistant Dean: Research, Innovation and Engagement and Senior Lecturer: Clinical Technology in the Faculty of Health and Environmental Sciences at CUT. The committee supported the novelty of the project and the contribution towards both applicants’ participation in the Future Professors’ Programme.
These projects are part of nine collaboration projects between researchers from the UFS and CUT that were approved for funding between 2019 and 2020. The funding ranges from R50 000 to R400 000. 

Using 3D printer technology 

Dr Fonternel says getting more funding than expected gives them the motivation to push through the obstacles presented by a project like this. 

“It is innovative and uncharted, so it helps to know that others also believe in the possibilities. Apart from the design, testing, and validation that this project aims to achieve, we are looking to broaden the scope into materials and sterilisation. We are also looking at acquiring equipment to enable the UFS to be able to design and manufacture devices of similar need and purpose,” says Dr Fonternel.

According to Dr Fonternel, who designed, developed, and then prototyped the video laryngoscope with the help of the Product Development and Testing Station (PDTS) at CUT, he hopes that with this new research, the validated technology of video laryngoscopy could be provided to a much larger medical community.

Prof Yadroitsau’s role is the overall project management, mechanical testing, project analysis, and possible additional fundraising.

“This can be beneficial to rural hospitals and centres with limited funds and equipment and can make a difference in the quality of care we provide to our patients. It has the potential to improve the safety of patients and healthcare workers in our current COVID-19 battle by bringing First World technology to the front line.” 

Valuable contribution to cancer research

Drs Brink and Makhafola will be collaborating on the development and testing of organometallic complexes, primarily model pharmaceuticals that can carry a radioactive metal centre. Their collaboration will develop model lead compounds and then test their biological activity, particularly for anticancer and antimicrobial activities, including toxicological profiling to determine if it is a viable option for future cancer treatment. 

“Drug development has significant challenges, particularly for academic institutions that do not have access to the focused and integrated specialty networks as developed by Big Pharma such as Roche, Novartis, Bayer, etc.  The research and development pathway of a new pharmaceutical agent that becomes commercially available, takes on average 12 years and costs approximately £1,15 bn.”

“For every single drug that receives approval, an estimated 10 000 compounds have been considered as viable options but have failed for one reason or another. Our research collaboration focuses on addressing these two main challenges that hinder academia from successfully entering the drug market.  We hope to identify potential lead compounds with novel mechanisms of action for the development of cancer therapeutics,” says Dr Brink.

This collaborative team hopes to promote and make a valuable contribution to cancer research, specifically towards the discovery of new effective cancer treatments/drugs. 

New ways of imaging patients with rheumatoid arthritis

Dr Evbuomwan Osayande, a nuclear medicine specialist at the UFS/Universitas Academic Hospital, says his research will compare the efficacy of EC-DG (ethylenedicysteine-deoxyglucose) imaging with ultrasound imaging in patients with rheumatoid arthritis. At this stage, the research is still in the protocol phase. A protocol has been submitted to the Health Sciences Research Ethics Committee of the UFS for approval. The project received R350 000. 

“If this imaging modality proves to be highly accurate and can detect disease activity, including low disease activity, much earlier than other investigational tools, it might become a routine imaging modality in the management of patients with rheumatoid arthritis,” says Dr Osayande, the principal investigator in this research.

If we can detect low disease activity with the EC-DG imaging, says Dr Osayande, it will ensure that the rheumatologists will continue patient treatment and thus prevent them from having complications, such as bone erosions and joint destruction. “It is an exciting project and we are all looking forward to the outcome.”

Embracing 4IR

The research project of Dr Thuthukile Jita, Senior Lecturer in the UFS School of Education Studies, and Dr Carlie Luzaan Schlebusch from CUT, investigates the possibilities and affordances of training student teachers to embrace the Fourth Industrial Revolution, specifically by learning to teach Science in schools using mobile devices and mobile apps. The project received R50 000 in funding.

“The study is perfectly timed amid the COVID-19 pandemic, which has resulted in large-scale disruption of schooling as we know it.  The call for teachers and learners and the education system generally to embrace technology and use information and communication technology (ICT) to continue and restore teaching and learning in some way, has been overwhelming.” 

“Consequently, there has been an almost overnight surge in the use of mobile devices for teaching and learning in schools. Sadly, the pandemic has further exposed the digital-divide reality that not all schools, teachers, and/or learners are able to engage effectively with the technology.” 

“Therefore, this study will assist in repositioning teacher preparation to use mobile devices and applications that are relevant for the topics covered in the national Curriculum and Assessment Policy Statement (CAPS) document, starting with the subject Natural Sciences for the senior phase, which include Grades 7 to 9,” says Dr Jita, who is the principal investigator of the project and who is also responsible for the conceptualisation and overall direction of the project milestones.

Research projects that have also received funding, include: 

• IoT-based early diagnostics of mobility challenges in the elderly by Elisha Markus (CUT) and Paul Kogeda (UFS). 
• Impact of urban development on environmental sustainability: Case study of Mangaung Metropolitan municipality by Dr SA Oke (CUT) and Dr Olusola Ololade (UFS).
• Promoting inclusive pedagogies through transformative learning modalities in multicultural educational settings by Dr June Palmer (CUT) and Dr Rantsie Kgothule (UFS).
• Optimisation of imaging protocols for maxillofacial reconstructive prosthesis design and modelling by Prof Deon de Beer (CUT) and Dr Jacques Janse van Rensburg (UFS).
• LET-MI-C project (Lumbar ErecTor spinae block spread using MRI and CT) by Dr Je’nine Horn-Lodewyk (CUT) and Prof Gillian Lamacraft (UFS).

Bloemfontein's quality of tap water compares very favourably with bottled water
2009-08-04

The quality of the drinking water of five suburbs in Bloemfontein is at least as good as or better than bottled water. This is the result of a standard and chemical bacterial analysis done by the University of the Free State’s (UFS) Centre for Environmental Management in collaboration with the Institute for Groundwater Studies (IGS).

Five samples were taken from tap water sources in the suburbs of Universitas, Brandwag, Bain’s Vlei, Langenhoven Park and Bayswater and 15 samples were taken of different brands of still and unflavoured bottled water. The samples were analysed at the laboratory of the IGS, while the interpretation of the analysis was done by the Centre for Environmental Management.

“We wanted to evaluate the difference in quality for human consumption between tap water and that of the different brands of bottled water,” said Prof. Maitland Seaman, Head of the Centre for Environmental Management.

“With the exception of two samples produced by multinational companies at their plants in South Africa, the different brands of bottled water used for the study were produced by South African companies, including a local small-scale Bloemfontein producer,” said Prof. Seaman.

According to the labels, the sources of the water vary from pure spring water, to partial reverse osmosis (as an aid to standardise salt, i.e. mineral, content), to only reverse osmosis (to remove salts). (Reverse osmosis is a process in which water is forced under pressure through a pipe with minute pores through which water passes but no – or very low concentrations of – salts pass.)

According to Prof. Seaman, the analysis revealed some interesting findings, such as:

• It is generally accepted that drinking water should have an acceptable level of salt content, as the body needs salts. Most mineral contents were relatively higher in the tap water samples than the bottled water samples and were very much within the acceptable range of drinkable water quality. One of the bottled samples, however, had a very low mineral content, as the water was produced by reverse osmosis, as stated on the bottle. While reverse osmosis is used by various producers, most producers use it as an aid, not as a single method to remove nearly all the salts. Drinking only such water over a prolonged period may probably have a negative effect on the human physiology.

• The pH values of the tap water samples (8,12–8,40) were found to be slightly higher (slightly alkaline), like in all south-eastern Free State rivers (from where the water is sourced) than the pH of most of the bottled water samples, most of which are sourced and/or treated in other areas. Two brands of bottled water were found to have relatively low pH levels (both 4,5, i.e. acidic) as indicated on their bottles and as confirmed by the IGS analysis. The health implication of this range of pH is not significant.

• The analysis showed differences in the mineral content given on the labels of most of the water bottles compared to that found by IGS analysis. The possibility of seasonal fluctuation in content, depending on various factors, is expected and most of the bottling companies also indicate this on their labels. What was a rather interesting finding was that two pairs of bottled water brands claimed exactly the same mineral content but appeared under different brand names and were also priced differently. In each case, one of the pair was a well-known house brand, and the other obviously the original producer. In one of these paired cases, the house brand stated that the water was spring water, while the other (identical) “original” brand stated that it was spring water treated by reverse osmosis and oxygen-enriched.

• Nitrate (NO3) levels were uniformly low except in one bottled sample, suggesting a low (non-threatening) level of organic pollution in the source water. Otherwise, none of the water showed any sign of pollution.

• The bacterial analysis confirmed the absence of any traces of coliforms or E.coli in any of the samples, as was also indicated by the bottling companies. This is very reassuring. What is not known is how all these waters were sterilised, which could be anything from irradiation to chlorine or ozone treatment.

• The price of the different brands of bottled water, each containing 500 ml of still water, ranged between R3,99 and R8,99, with R5,03 being the average price. A comparison between the least expensive and the most expensive bottles of water indicated no significant difference in quality. In fact, discrepancies were observed in the most expensive bottle in that the amount of Calcium (Ca) claimed to be present in it was found to be significantly different from what the analysis indicated (29,6 mg/l versus 0,92 mg/l). The alkalinity (CaCO3 mg/l) indicated on the bottle was also found to differ considerably (83 mg/l versus 9,4 mg/l). The concentration of Total Dissolved Salts (TDS) was not given on the product.

“The preference for bottled water as compared to Bloemfontein’s tap water from a qualitative perspective as well as the price discrepancy is unjustifiable. The environmental footprint of bottled water is also large. Sourcing, treating, bottling, packaging and transporting, to mention but a few of the steps involved in the processing of bottled water, entail a huge carbon footprint, as well as a large water footprint, because it also requires water for treating and rinsing to process bottled water,” said Prof. Seaman.
