Your kindness is contagious
Counselling psychologist at the university, Nhlori Ngobeni, believes that what you give to others does not necessarily leave your life; it comes back to you in some way or another, for the benefit of your health and well-being.

The month of October has been declared Mental Health Awareness Month, with the objective of not only educating the public about mental health, but also to reduce the stigma and discrimination to which people with mental illness are often subjected.

The COVID-19 global pandemic and the subsequent implementation of the lockdown have had an impact on all aspects of our lives: family, relationships, the economy, educational institutions, health system, to name a few.

As stipulated by the South African Department of Health and the South African Federation for Mental Health, mental-health problems come as the result of a complex interplay between biological, psychological, social, and environmental factors.

With that being said, University of the Free State (UFS) counselling psychologist and writer of the article Ubuntu, Nhlori Ngobeni, explains that the demands of our changing world can become quite overwhelming, leaving one feeling burdened by all the changes they need to make. She reflected on the increased challenges that students have experienced in their academics, physical and mental health, finances, and interpersonal relationships as a result of the pandemic, and how the spirit of Ubuntu can act as a catalyst of support.

Nelson Mandela defined Ubuntu as “the profound sense that we are human only through the humanity of others; that if we are to accomplish anything in this world, it will in equal measure be due to the work and achievement of others”.

Exercising your humanity through actions, words, gestures,
and thoughts can aid the sustenance of humanity.


Benefits of Ubuntu

Ngobeni further elaborated that living out your humanity should not be done to get something in return. She explained the essence and benefits of Ubuntu as the belief that being kind to others is like planting a seed and watering it daily. “It is guaranteed to yield some fruits. What you give to others does not necessarily leave your life; it comes back to you in some way or another, for the benefit of your health and well-being,” she added.

Ubuntu in action
Exercising your humanity through actions, words, gestures, and thoughts can aid the sustenance of humanity.

Here are some ways you can live out your humanity:

Live out your values: showing love; caring for and respecting others; choosing to forgive; having sympathy and empathy; being kind and compassionate.
Acts of service: spending time with others; sharing your knowledge; running an errand for the elderly; making a cup of tea for your parents or organising a movie or games night for your family.
Giving: food, clothes, time, or money.
• Being intentional: being genuine and present in your everyday experiences or encounters. Calling a classmate or friend and checking on them.
• Gestures: greeting, nodding, smiling, waving, etc. … simply acknowledging others.

Researcher part of project aimed at producing third-generation biofuels from microalgae in Germany

A researcher from the University of the Free State (UFS), Prof Johan Grobbelaar, was invited to join a group of scientists recently at the Institute for Bio- and Geo-Sciences of the Research Centre Jülich, in Germany, where microalgae are used for lipid (oil) production, and then converted to kerosene for the aviation industry.

The project is probably the first of its kind to address bio-fuel production from microalgae on such a large scale.  

“The potential of algae as a fuel source is undisputed, because it was these photoautotrophic micro-organisms that were fixing sunlight energy into lipids for millions of years, generating the petroleum reserves that modern human civilisation uses today.  However, these reserves are finite, so the challenge is marrying biology with technology to produce economically-competitive fuels without harming the environment and compromising our food security.  The fundamental ability that microalgae have to produce energy-rich biomass from CO2, nutrients, and sunlight through photosynthesis for biofuels, is commonly referred to as the Third-Generation Biofuels (3G),” said Prof Grobbelaar.

The key compounds used for bio-diesel and kerosene production are the lipids and, more particularly, the triacylglyserols commonly referred to as TAGs.  These lipids, once extracted, need to be trans-esterified for biodiesel, while a further “cracking” step is required to produce kerosene.  Microalgae can store energy as lipids and/or carbohydrates. However, for biofuels, microalgae with high TAG contents are required.  A number of such algae have been isolated, and lipid contents of up to 60% have been achieved.

According to Prof Grobbelaar, the challenge is large-scale, high-volume production, since it is easy to manipulate growth conditions in the laboratory for experimental purposes.  

The AUFWIND project (AUFWIND, a German term for up-current, or new impetus) in Germany consists of three different commercially-available photobioreactor types, which are being compared for lipid production.

The photobioreactors each occupies 500 m2 of land surface area, are situated next to one another, and can be monitored continuously.  The three systems are from Novagreen, IGV, and Phytolutions.  The Novagreen photobioreactor is housed in a glass house, and consist of interconnected vertical plastic tubes roughly 150 mm in diameter. The Phytolutions system is outdoors, and consists of curtains of vertical plastic tubes with a diameter of about 90 mm.  The most ambitious photobioreactor is from IGV, and consists of horizontally-layered nets housed in a plastic growth hall, where the algae are sprayed over the nets, and allowed to grow while dripping from one net to the next.

Prof Grobbelaar’s main task was to manipulate growth conditions in such a way that the microalgae converted their stored energy into lipids, and to establish protocols to run the various photobioreactors. This was accomplished in just over two months of intensive experimentation, and included modifications to the designs of the photobioreactors, the microalgal strain selection, and the replacement of the nutrient broth with a so-called balanced one.

Prof Grobbelaar has no illusions regarding the economic feasibility of the project.  However, with continued research, optimisation, and utilisation of waste resources, it is highly likely that the first long-haul flights using microalgal-derived kerosene will be possible in the not-too-distant future.

Prof Grobbelaar from the Department of Plant Sciences, although partly retired, still serves on the editorial boards of several journals. He is also involved with the examining of PhDs, many of them from abroad.  In addition, he assisted the Technology Innovation Agency of South Africa in the formulation of an algae-biotechnology and training centre.  “The chances are good that such a centre will be established in Upington, in the Northern Cape,” Prof Grobbelaar said.
