Victoria the mannequin has become a familiar face in Nursing classrooms

She has an uncanny ability to move her eyes towards the sound of voices in a room, her voice shrills and squeals when she's in pain, she throws in a Spanish word or two, and she releases bodily fluids just like a real human would. 

These are just some of the quirky characteristics that make up the new R1,76 million-rand birthing mannequin in the School of Nursing's Simulation Unit, who goes by the name Victoria. She weighs more than 80 kg and is almost 1,7 metres high. With features such as real eyelashes, eyebrows, and hair, you can't help but do a double take when you lay eyes on her. 

Students getting practical experience

While the unit has other mannequins used for training Nursing students in each year or their study, Simulation Coordinator from the School of Nursing in the Faculty of Health Sciences, Cecile Fourie, said Victoria was a major upgrade for the school because of her versatility. Victoria would further enhance the school's quality of teaching by training students in their final year of undergraduate studies as well as those pursuing their postgraduate studies, about the ins and outs of pregnancy and other female morbidities, Fourie said. 

"We try to make our scenarios as real and authentic as possible and we've seen how much our students have grown. Introducing Victoria to our pre- and postgraduate students will prepare them to be competent in clinical practice."

So, what exactly can Victoria do? 

Fourie said while the other mannequins were made with screws that made them look robot-like, Victoria was made with silicone and given a clean finish to make her appear life-like. The other mannequins can only blink, but Victoria's eyes move around, she can speak Spanish and French, and she comes with five tummies for different medical scenarios. She has a normal tummy which acts as a closure, an operable tummy for caesarean delivery, a tummy that allows a breeched baby to be twisted and turned from the outside just before delivery, a contraction tummy used for normal vaginal delivery – which also allows Victoria to push, bleed, urinate, and release mineral oil which acts as amniotic fluid. The fifth tummy is postpartum haemorrhage, a condition that is common among South African mothers after delivery. 

"It’s so good that we get to train our students in such real, lifelike circumstances. Through Victoria we're going to try and do our part in lessening maternal deaths, which are so prominent in our country. She can act out all the abnormalities that take place in a real delivery, and she can also have other medical conditions such as a heart attack," Fourie said.

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.
