Dr Anamika Megwalu, an assessment and engineering librarian at San Jose State University in California in the United States (US), addressed a group of staff from the UFS Department of Library and Information Services.

Dr Anamika Megwalu, an assessment and engineering librarian at San Jose State University in California in the United States (US), pointed out that building a lasting and sustainable relationship with departments and upholding quality in the library environment is key. 

She addressed a group of colleagues from our Department of Library and Information Services (LIS) on 25 November 2020.

Tight budgets call for proper assessment

Her presentation, titled Library Collection Development, was aimed at sharing her experience of working in the collection development and liaison sections within the LIS ecosystem. 

“This librarian-cum-computer science lecturer has the benefit of both worlds, having worked in private and public academic libraries such as Stafford University and City University of New York respectively,” says Monde Madiba, Deputy Director: Collection Development and Management of LIS at the University of the Free State.

San Jose, the oldest public university in the western US, is located in the heart of Silicon Valley, serving more than 33 000 students enrolled in 10 colleges and 67 departments.

According to Dr Megwalu, the tight budgets that public academic libraries such as San Jose receive, call for proper assessment of library collections in order to deal with the constraints. She emphasised the need to “uphold quality within the constraints”.

Moving from collecting information to creating information

Some of the ideas that Dr Megwalu shared for conducting assessment and collection development, includes the following:
• Change the library’s image from being a collector of information to being the creator of information.
• Consider the size of the different departments: some may need little or no attention due to size, while others may need close attention due to intensive research by lecturers within the department.
• Identify gaps and focus your attention on filling them with the relevant collection.
• Make sure that you are aware of the accreditation period of different programmes, since the role that academic libraries play in collection development is recognised by such agencies.
• Build a lasting and sustainable relationship with departments. This includes knowing the lecturers’ research interests, assisting the newly established departments, attending free webinars, and participating in student activities.
• Ensure equal distribution of the budget and ensure that everyone has equal access to it.
• Create a timetable where everyone knows when to submit requests for prescribed books. Make it clear that it takes approximately three weeks on average for ordered books to be delivered.
• Develop department-specific collection development policies.
• Be ready to move with the times, e.g. replace DVDs in favour of video-streaming services.
• Shift towards a 100% electronic reference collection.
• Consider having an electronic version for popular but currently in-print collections.
• Develop an indigenous collection based on the contributions of communities around the university.
• Create a portal for open educational resources (OERs) from participating institutions across the globe.

“Dr Megwalu’s presentation was not only informative but a testimony that collection development and assessment are dynamic and driven by passion and love,” says Madiba.

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.
