Dr Ocaya
Dr Richard Ocaya’s research addresses the skills development and transfer millennium goal of many governments globally.

With the Fourth Industrial Revolution becoming a reality, Dr Richard Ocaya’s research is receptive to the fact that Africa and the world need to re-imagine their research. His research focuses on electronic instrumentation design for scientific measurements, computational physics on atomic nano-atomic structures, and semiconducting organic compounds materials built on silicon to realise Schottky devices.

Software developer 
“I develop most of the instrumentation that I apply in my research – both software and hardware,” said Dr Ocaya, a Physics Lecturer and Programme Director: Physics and Chemistry on the UFS Qwaqwa Campus.

“I am active in scientific computing through the computing cluster and software development, mathematical physics for material science modelling, and embedded instrumentation design using microprocessors. I also have deep interest in radio and data telemetry, in which I hold a South African patent issued in 2013. My present international collaborations are with like-minded researchers in similar fields in Saudi Arabia, Turkey, Japan, Egypt, South Korea, and the United States,” he added.

How does his research talk to the real world?
“The driving principle of all areas of my research has always been to deploy cutting-edge research to actual, real-world applications for the immediate betterment of Africans. The areas of my research align closely with the millennium goals of many governments globally, including the Republic of South Africa. These goals pertain to skills development and transfer that position us to better address the challenges of energy, water, and other priorities.”

Dr Ocaya is currently co-promoting a PhD student, having previously supervised one PhD, two MSc, and more than twenty honours students. He is a self-taught electronics and computer programmer, whose curiosity led him to question ‘the voices and music coming from a box; a radio’. “In my quest to satisfy my curiosity, I collected many discarded devices, took them apart, and tried so many circuits, only to have them fail because the theory was lacking. After thousands of failed projects and with me barely thirteen and in lower secondary school, my first ever project actually worked,” he said.

NRF-rating
He is the author of the book Introduction to Control Systems Analysis using Point Symmetries: An application of Lie Symmetries, which is available in all major bookstores such as Amazon, in both print and e-book format. He is a C3 NRF-rated researcher whose work makes a pioneering contribution to the new and growing field of phononics, an independent field of the now established photonics.

“This field will someday lead to improved energy-storage devices and faster processors due to more efficient heat removal from nanodevices,” he concludes.

Successful conviction on edible oil adulteration
2009-03-28

A successful conviction in the South African food industry for selling diluted olive oil under the guise of virgin olive oil was handed down in the Special Commercial Crimes Court in Durban this week.

Salvatore Pollizi, owner of the company Ital Distributors, pleaded guilty in terms of Section 105A of the Crime Prosecuting Act to selling fake virgin olive oil under the names of Antico Frantoio and Ulivo.

He was sentenced to a fine of R250 000 or three years’ imprisonment, of which R130 000 or 18 months imprisonment is suspended for five years, on condition that he is not found guilty of fraud or theft or an attempt to commit such crimes during the period of suspension.

The offence was committed in 2001 when the scandal involving olive oil being mixed with a cheaper edible oil and being sold as the more expensive virgin olive oil was uncovered by scientists from the University of the Free State (UFS) in Bloemfontein, in collaboration with Mr Guido Costas, The Olive Growers’ Association, AgriInspec and the South African Police Services.

According to Prof. Lodewyk Kock, Head of the South African Fryer Oil Initiative (SAFOI) that is based at the UFS, the conviction is to his knowledge the first successful conviction of this kind in the South African food industry.

Prof. Kock said, “The court’s decision on Monday, 23 March 2009 is good news to our country and sends out a dire warning to all fraudsters in the food industry.”

He attributed the successful conviction to the active and enthusiastic participation by Advocate Joanna Bromley-Gans from the Special Commercial Crime Unit (SCCU) in Durban, Captain Pragasen Govender from the Serious Economic Offences Unit (SEOU) in Pretoria and the team from SAFOI.

Prof. Kock said that in 2003 some of the prominent members of the edible oil industry took responsibility for the authenticity of their own oils by appointing outside laboratories for routine monitoring.

In some cases a seal of approval from such laboratories is displayed on the monitored oil containers. This is an attempt to inform oil distributors, shop buyers and consumers that these oils have been monitored by an outside laboratory for authenticity.

This “policing” has been supported by major role players in the fast-food sector like Nando’s, Spur, Captain Dorego’s, King Pie Holdings, etc. and various oil distributors like Felda Bridge Africa, Willowton Oil & Cake Mills, Refill Oils, etc.
