AFRICA MONTH 2023

Theme: Promoting and appreciating knowledge in and from Africa

On 25 May 2023, Africa will celebrate the 60th anniversary of the Organisation of African Unity (OAU), now the African Union (AU). In continuance of the University of the Free State's (UFS) long tradition of commemorating Africa Day and the ideas underpinning it, the UFS will once again celebrate Africa in 2023 by organising diverse commemorations. The commemorations will highlight African indigenous knowledge and its relevance for higher education in South Africa and beyond. The interpretation and transfer of African indigenous knowledge will be celebrated through music and dance.

Africa Day memorial lecture

The highlight of the celebrations will be the Africa Day memorial lecture, hosted by the university's Centre for Gender and Africa Studies on Wednesday 24 May 2023. The speaker is Prof Motlatsi Thabane, formerly of the National University of Lesotho. The title of his presentation is Friendship in the Search for Justice in Mohokare Valley in the Nineteenth Century. The departure point of Prof Thabane’s lecture is the early 19th century. 

He demonstrates that a community of white settlers fleeing British rule in the Cape Colony was added to African communities living in the Mohokare Valley at the beginning of the 1830s. As a result, complex relations developed between African and white settler communities in the Mohokare Valley. Central to those relations was occupation and ownership of land. Driven by different motives and influences, some African communities threw in their lot with incoming white settler communities, while others resisted the alienation of land they regarded as theirs. 

Moshoeshoe I and his followers were among the latter groups. Consequently, relations that developed between Basotho and white settlers were characterised by deep mutual mistrust, tension, and conflict. White settlers were not a monolithic group, however, and among them were individuals who regarded the alienation of Africans’ land as unjust. Josias Philip Hoffman was one such individual. Concerned about the welfare of the Basotho and opposed to the unjust manner in which fellow settlers seized their land, he formed a friendship with Moshoeshoe I, and lent a hand to Moshoeshoe I’s resistance against the alienation of the Basotho’s land. The purpose of the lecture is twofold; first, to celebrate the friendship between these two men, and second, to ask questions about whether we can learn something from this friendship today.

Africa Month book launch 

The memorial lecture will be preceded by a book launch on 22 May. The UFS Library and the Centre for Gender and Africa Studies will facilitate the launch of the book titled, Decolonizing The Mind: A guide to decolonial theory and practice by Sandew Hira, Secretary of the Decolonial International Network (DIN). The book attempts to offer a comprehensive, coherent, and integral theoretical framework that draws on different contributions in the resurgent and insurgent decolonial movement. Hira will use the book launch to make a clarion call for a new world civilisation anchored in the decolonisation of the mind. 

The Africa Month Dialogue, slotted for 26 May and facilitated by the Office for International Affairs, will carry the same theme as the memorial lecture, namely, ‘Promoting and appreciating knowledge in and from Africa’. Together with the Rector and Vice-Chancellor, Prof Francis Petersen, and international partners, we will discuss the meaning and value of African indigenous knowledge, the importance of being creators and co-creators of knowledge in and from Africa, and the importance of African knowledge on the international stage. Of importance is the idea of African ways of being, knowing, and relating. In the engagement, internationalisation of African knowledge will be considered without necessarily compromising Africa’s ability to integrate and engage on a global level. The UFS’ approach to promoting African-produced knowledge and epistemological diversity and disseminating knowledge in and from Africa will be deliberated. 

Hybrid format 

The 2023 UFS Africa Month commemorations will once again take a hybrid format. Besides the Africa Day memorial lecture, the book launch, the Africa Day Dialogue, and various face-to-face functions on all three campuses, there will also be online content on a dedicated website. We are looking for contributions that engage with knowledge. Among others, UFS community members and its international partners are invited to make contributions centred on promoting and appreciating knowledge in and from Africa by way of contributions centred on, but not limited to the themes below: 

Exploring how knowledge in and from Africa is promoted and appreciated

• The role of orality in creating new understanding and insight 
• The potential of oral traditions and oral history for knowledge creation, transfer, and dissemination 
• Women in African knowledge processes
• Personal biography’s position in knowledge generation
• African land tenure systems
• African languages and knowledge creation
• Indigenous healing systems and pandemics
• Memory and knowledge creation
• African conflict resolution mechanisms and practices
• Ubuntuism 
• Indigenous knowledge in Africa
• The national, regional, and global impact of African scholarship
• UFS knowledge collaborations/partnerships on the African continent
• Narratives of research and student excellence associated with African unity 
• Dissemination of knowledge in and from Africa
• Celebrating epistemological diversity in and from Africa.

Other forms of contributions/participation can include, but are not limited to
• recorded performing arts performances (e.g., solo music or poetry);
• virtual visual art presentations;
• written poetry;
• songs;
• short thought/opinion pieces, which can also be published in mainstream media; 
• topical academic writings;
• face-to-face events; and 
• live-streamed events (with links to the Africa Month webpage).

Please share a brief written proposal explaining your planned contribution by 12 May 2023. The proposal should not exceed 300 words and should be emailed to Bhekumusa Zikhali at zikhalibn@ufs.ac.za / Africadaycommemoration@ufsacza.onmicrosoft.com.

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.

 

Figure 1. Yeast cells exposed to over-used cooking oil. Wart like protuberances/ outgrowths (WP) is clearly visible on the surfaces of the elongated yeast 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.
