Dr Kundai Manamere and Dr Hlengiwe Dlamini

The International Studies Group continues to keep critical issues in Africa on the research agenda, with two of its postdoctoral research fellows awarded prestigious international research grants.

Dr Hlengiwe Dlamini won a CODESRIA (Council for the Development of Social Science Research in Africa) award as part of the organisation’s ‘Meaning-making Research Initiatives’. These initiatives focus on supporting research that contributes to agendas for imagining, planning, and creating African futures.

“I was over the moon when I heard that I received this award!” says an excited Dr Dlamini. “The competition was a tough one. Applications were received from 430 female applicants and just 12 were retained, including mine.”  
 
Her colleague in the ISG, Dr Kundai Manamere, who recently signed a book contract with Ohio University Press, has been awarded an African Peacebuilding Network (APN) 2020 Individual Research Fellowship, administered by the American Social Science Research Council.

“I am delighted to have received this award. As an early-career scholar, this is one of my several goals, and achieving it recognises and validates my work. This boosts my confidence and encourages me to keep working hard,” says Dr Manamere.

Examining border disputes
Dr Dlamini’s research project is a comparative study of two border disputes – between Cameroon and Nigeria over the Bakassi Peninsula borderland, and between Eswatini (formerly Swaziland) and South Africa over the demarcation of their borders, and how the international doctrine of uti possidetis juris, as an instrument of inter-state conflict resolution, applies to these disputes.

“The doctrine of uti possidetis juris (literally translated: as you possess, thus may you possess) states that frontiers inherited from colonialism cannot be changed under any circumstance. Cameroon won its case in the International Court of Justice in 2002 in its border dispute with Nigeria and this had a direct impact on Eswatini, which also had a border dispute with South Africa,” she explains.

“The post-apartheid South African governments have been hostile to the idea of adjusting their borders with Eswatini, while the Eswatini monarchy has relentlessly been pursuing what it calls ‘its stolen territories by the British and the Boers in the 19th century’.”

Dr Dlamini will be heading a team of four female researchers from different nationalities. As soon as international flights resume, two scholars from Canada and Sweden will head for Cameroon, while she and another researcher will start with archival research in Southern Africa, before embarking on fieldwork.

“There will be no rest for us. It is incumbent on me to assemble the data collected and use it to write two or three scholarly articles for journal publications,” says Dr Dlamini.


Migration issues and public health interventions
Dr Manamere’s research focuses on documenting the experiences of former refugees and their host communities at Chambuta refugee camp, one of the five refugee camps established by the Zimbabwean government along the Mozambican border in the 1980s to accommodate asylum seekers fleeing from the Mozambican civil war.
“The project explores their experiences and examines their perceptions about conflict, displacement, refugee conditions, and the occurrence of diseases and intervention following a disease outbreak that killed nearly 200 people in August 1992. I use the Chambuta case to reflect on the politics of voice and representation in history – how official reports by governments and non-governmental organisations overshadow the experiences of refugees and host communities.”

The COVID-19 lockdowns in both South Africa and Zimbabwe have delayed Dr Manamere’s fieldwork plans. She will now first spend time collecting information from digitised archives and doing telephonic and online interviews.

ISG a melting pot for international research talent
Both researchers expressed their appreciation for the role the ISG has played in shaping their academic careers.
“By creating opportunities for me to network with renowned historians in my field, the ISG has expanded my circle of mentors. All these opportunities culminated into several achievements, including this award, forthcoming articles in leading international journals, presentations at international conferences, and a book due to be published by the Ohio University Press, one of the leading Africanist publishers in the world. To me, this is the best foundation for a successful academic career, and I am proud to be part of the group,” says Dr Manamere.

“The ISG creates one of the most convivial environments for intellectual production.  We are really flying high. The scholars of the ISG are making their mark in different ways. I am very grateful for the Stanley Trapido seminar series and other academic activities that constitute a vital crucible for the cross-fertilisation of our minds and for the acquisition of new methodologies and updates in our disciplines,” says Dr Dlamini.

Prof Ian Phimister, Head of the ISG, says the two researchers have brought great credit to the UFS and the ISG.“By winning such prestigious awards, Drs Dlamini and Manamere show themselves to be first-rate scholars. Their academic commitment and drive are exemplary. At the same time, their research projects, respectively on comparative African territorial boundary disputes and on Mozambican refugees' experiences of civil war, drought, and disease, have significant policy-making implications.”

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
