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.

HIV/AIDS could kill 20% of southern Africa’s farm workers by 2020
2008-09-27

HIV / AIDS is claimed to account for 40% - 50% of infections in the workforce in some labor-intensive industries. This means that every farmer will have to replace up to 50% of his workforce within the next 10 years.

This was said by Mrs Estelle Heideman (pictured) of the Faculty of Natural and Agricultural Science at the University of the Free State (UFS) at the launch of a DVD about a project to equip farm workers with knowledge and skills regarding HIV / AIDS.

Mrs Heideman was quoting the research findings of Agrimark Consultant, Johan Willemse, and added that farm workers, because of low literacy levels, remoteness of the areas in which they live and the distances to health care facilities, are often forgotten when it comes to HIV/AIDS prevention and care programmes.

This weekend Mrs Heideman leaves for New York City to take up a scholarship awarded to her by the University of Columbia and the University of California, Los Angeles (UCLA) to participate in the M-A-C AIDS Sponsored Leadership Programme.

The leadership Initiative provides a structured support program to enable participants to exchange best practices in the approach to HIV prevention that can be adapted to local circumstances. At the conclusion of the program the Leadership Initiative will, amongst other benefits, provide funds for Fellows to carry out their prevention program in South Africa.

Such a program was already carried out from February to May this year as part of the Lengau Agri Centre’s Farm Project in collaboration with the Chief Directorate Community Service at the UFS on the farms Slangfontein, Dwarsrivier and Pypersfontein in the Philippolis district.

According to Mrs Heideman, who is the co-coordinator of the project, the aim of this project was to equip farm workers with knowledge and skills regarding HIV/AIDS so that they can take control of their lives and make quality decisions.

“A major advantage of working with farm workers is that the whole family is included in the session and this ensures that all generations get the same message”, she said.

At the end the feedback from the farm workers about the programme was positive. “Many said they had tested for HIV and will continue to do so to ensure that they would be around to see their children grow up”, said Mrs Heideman.

Copies of the DVD can be obtained from Estelle Heideman (0828211230) or Tarryn Nell (0832573843).
