Dr Emmanuel Arko-Cobbah, Senior Lecturer and Medical Specialist in the Department of Surgery at the University of the Fee State (UFS) and a trauma surgeon, has recently been inducted as a Fellow of the American College of Surgeons (ACS).

Dr Emmanuel Arko-Cobbah, Senior Lecturer and Medical Specialist in the Department of Surgery at the University of the Fee State (UFS), says he hopes his induction as a fellow of the American College of Surgeons (ACS), will show the world that South Africa also produces great doctors from whom they can learn.

The ACS is dedicated to improving the care of the surgical patient and safeguarding standards of care in an optimal and ethical practice environment. Dr Arko-Cobbah was inducted on 19 October after a rigorous process. He was part of 1 800 candidates from around the world, but mostly from North America, with about 600 from other countries outside of the US and Canada.

Dr Arko-Cobbah, a trauma surgeon, says it feels surreal as it has always been his dream to become a Fellow of the American College of Surgeons, although it often felt like an impossible dream. “I truly thank God, and I am very grateful, because to me, it feels like it's all part of His plans for me, that is why He is making these things possible for me.

“As a trauma surgeon, it makes me feel I have achieved even beyond our borders, and it gives me the opportunity to also share the knowledge we have locally with the rest of the world. We have a lot to offer, but we tend to get underestimated because of where we’re from,” says Dr Arko-Cobbah.

To become a fellow of the ACS, applicants go through a selection process after applying and then they need to be nominated by three different fellows of the American College who are in good standing. If their nominations get accepted, an interview follows whereafter the reports are reviewed by the committee which then decides the outcome.

South Africa produces great doctors

According to Dr Arko-Cobbah, he hopes to put the UFS on the map with this lifelong fellowship so that the world can know South Africa also produces great doctors and that they can learn from these doctors. “The other side of the coin is for me to inspire others to also aim to get into the American College, and to dream even bigger than this. If I could do this, then anybody can. Partner with God, and dream big dreams, and make big plans. That is what I was taught by Pastor At Boshoff since I was a student, and God has always been faithful.”

After qualifying as doctor and becoming a general surgeon at the UFS, and super specialised as a trauma surgeon, Dr Arko-Cobbah completed a Surgical Leadership Programme with Harvard University in Boston, in the US. “God has always been good to me, and I am forever grateful to the support of my wife and family and continued inspiration and mentorship from Prof André Loubser. I am grateful to the late Prof Theron, and the UFS Surgery Department, past and present, for always pushing me to be better.

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
