Dear UFS NSFAS and Funza Lushaka student,

You have been identified as an eligible student of the University of the Free State (UFS) who will receive a 3-month data-bundle grant, downloaded directly to your mobile device, as provisioned through a grant from the Department of Higher Education, Science and Innovation.   

Specifics of this data-bundle allocation are:

1. This grant is available only to students funded by NSFAS and Funza Lushaka.
2. The grant has a fixed duration of 3 months only, commencing on the date of your full registration with the national telephone company.
3. There are no in-month data top-ups on these allocations. Once this data allocation has been used, all further data required for academic engagements with the UFS will be for your own account.
4. The data will be provisioned directly to your mobile device from your preferred (contracted) mobile data provider on a monthly basis (for 3 months only).
5. No VPN access (through GlobalProtect) is required when accessing the academic websites of the UFS through these data bundles.
6. Your mobile number on the university’s PeopleSoft system will be used to initiate the download of the data bundles. You need to make sure that the cell number we have is your correct number. This cannot be changed afterwards.
7. There is no roll-over facility for unused data. A fresh, automatic provision will be made on a monthly basis. Unused data will not be added to the data bundles of the following month (3 months only).

NEXT STEPS

1. Telkom subscribers:

Based on the DHET grant conditions, a national agreement was reached with Vodacom, MTN, and Cell C for cell-based data provisioning. Unfortunately, the same agreement could not be reached for Telkom subscribers. The Telkom offer is based on an ADSL facility installed at your place of study and is thus based on a fixed landline approach. This implies that if you do not have a fixed landline to your home (place of study), you need to apply for an ADSL facility to be installed.  The associated arrangements and costs are for your personal account.

• If you do not have a Telkom landline at home (place of study), and you prefer to be serviced through a mobile data facility, you can opt for a 3-month engagement with any of the other three mobile data providers, being Vodacom, MTN, and Cell C. In this regard, you must physically visit the preferred provider and buy a SIM card and provide the new SIM-card number to the Student Helpdesk at Student Academic Services (051 401 9666) BEFORE 14:00 on Friday 26 June 2020, as this number will now be the number to which the data bundle will be provisioned for the 3 months.  

To do so, proceed as follows:

• Select the provider you want to deal with, or which is closest to you.
• Go to the shop (outlet) and buy a new SIM (at your own cost).
• You must take your national ID and proof of residence with you to RICA the new SIM card (as per the legal requirement).
• After obtaining the new SIM card, you must provide the new cell number attached to the SIM card to the UFS through the Student Helpdesk at Student Academic Services (051 401 9666) BEFORE 14:00 on Friday 26 June 2020.
• If you prefer to update your cell number yourself, please use the following URL:

https://pssa.ufs.ac.za/csprd/signon.html

2. Please note:

Once the monthly data allocation has been downloaded to the pre-identified cell number of your chosen mobile data provider (Vodacom, MTN or Cell C), the use of the data must be carefully managed for academic purposes only.  

Should you, for whatever reason, use this data inappropriately (for private use, etc.), you will run out of data soon, as it is a limited allocation of 10 GB of daytime data and 20 GB after-hours data (30 GB in total). NO further monthly data top-ups are available to you under this grant, and all further data requirements will be billed against your private number until the next monthly allocation is downloaded to your device (3 cycles only).

3. The GlobalProtect VPN access mechanism is not required for this data use, and your access will be directly to the internet and the UFS website, from where you will be able to engage with the academic content published there.

4. Technical setup assistance:

• Once you have received your monthly data bundle, you will have to set up your mobile device as a hotspot and link your laptop or desktop device to it. The cellphone then acts as a modem through which you will be able to engage with the academic resources of the UFS.
• There is no ongoing data usage monitor to inform you of the volumes of data you have consumed per session or per day. Be careful how you manage this data.

5. General notes:

• Please make sure that we have your correct cell number on our PeopleSoft system. The final date for any changes or confirmation of your correct cell number is 14:00 on Friday 26 June 2020.  Unfortunately, no late cell number changes can be accepted thereafter.
• If you are a current Telkom subscriber, you will have to provide the number of the new SIM card to the UFS as well. Should you miss the deadline of 26 June 2020, there will be no further opportunities to correct your number, and data that should have been allocated to you, will now be used by another person for the full duration of the grant, being 3 months.
• You are not allowed to change your mobile number in the next 3 months, as the data-bundle allocation will be done in a once-off manner and will remain as such for the full duration of the data grant.

6. Technical setup guides:

Please refer to the UFS website’s Digital Life section under the ‘Student’ heading, for guides to set up your mobile phone as a hotspot and to link your laptop or desktop to your phone.

This is a valuable once-off grant by the Department of Higher Education, Science and Technology. You are encouraged to perform all the actions required to use this data optimally.

7. Enquiries:

For enquiries regarding the technical configuration of your device, please contact:

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.
