Taking a nation’s health to heart

first_imgCooking from the Heart contains recipes from ordinary South Africans from a wide range of cultures. All recipes have been adapted by experts to be healthier.(Image: Cooking from the Heart)MEDIA CONTACTS• The Heart and Stroke Foundation+ 27 21 403 6450RELATED ARTICLES• Bridging the public healthcare gap• Getting Africa’s youngsters moving• Mandela’s chef publishes cookbook• The simple palate of Nelson MandelaRay MaotaSeptember is widely known as Heritage Month in South Africa, with the country’s multi-cultural makeup celebrated each year around this time, but it is also National Heart Awareness Month, and this year a recipe book that encourages healthy eating will be made available to help raise awareness on heart disease.Cooking from the Heart is a joint initiative between the Heart and Stroke Foundation of South Africa (HSF) – an NGO that has been active in raising awareness on the subject of non-communicable diseases for 32 years – and Pharma Dynamics, a supplier of medicine for cardiovascular disease (CVD), to encourage South Africans to cook, and eat, healthier.CVD claims about 200 lives in South Africa daily, making it the second leading cause of death after HIV/Aids.More than just a cookbookCooking from the Heart contains recipes from ordinary South Africans that celebrate a wide range of cultures. Over 2 000 entries for everyday recipes were submitted for the initiative, and a team made up of dieticians from the HSF, with the help of food consultant Heleen Meyer, selected over 70 of these, which are featured in the book.The recipes were then adapted by the team, who modified ingredients like fat, salt and sugar in an effort to boost the nutritional value of the food to keep in line with the HSF’s healthy eating guidelines.Copies of the book will be distributed to the public for free, and through efforts endorsed by the National Department of Health, hospitals and other public institutions across the country will also be able to serve patients healthier meals based on the information contained in the book.“We’ve launched many initiatives over the years, but never one quite like Cooking from the Heart,” said Vash Mungal-Singh, CEO of HSF. “It offers the public a practical resource to tackle non-communicable diseases that are closely linked to poor diet.“We hope that everyday cooks will see how easy it is it to make favourites like potato salad or beef stew, healthier.”Also in the book are basic guidelines for healthy eating, ideas for healthy shopping on a budget and tips for reading food labels.“This book is a heart-friendly, multi-cultural, budget cookbook by South Africans, for South Africans,” said Paul Anley, managing director and CEO of Pharma Dynamics. She also founded the company in 2001.CVD on the riseThe initiative received praise from health minister Aaron Motsoaledi, who called it a bold and practical step against heart disease and stroke. Motsoaledi has been an outspoken advocate for healthier living among South Africans since taking up office in 2009.In an interview with The Times newspaper in July, he expressed concerns over the escalating costs of healthcare not only in South Africa, but globally, because of the public’s ignorance of the impact of unhealthy lifestyles.A statement released by Motsoaledi’s department in 2011 shows the conclusion of research done on non-communicable or lifestyle diseases by the UN, in which it was said that these diseases were expected to account for 69% of global deaths by 2030.“The idea of researching and publishing recipes that are both economical and culturally appropriate is an excellent way of creating awareness,” said Motsoaledi. “It is a concrete means for people in all communities to improve their overall health.”Mungal-Singh also quoted from the UN research and said that by 2030 the world body predicts that deaths of South Africans aged between 35 to 64-years by CVD will have skyrocketed by 40%.“Cardiovascular disease is a growing problem in South Africa as the intake of saturated and trans-fats, salt and sugar is on the increase,” she said. “Nutrition is a very important part of managing and preventing heart disease and stroke.”She added that another contributing factor to the rise in CVD cases was people’s misconception that a healthy diet is expensive, impractical or unappetising.“Cooking from the Heart will dispel that myth once and for all,” said Mungal-Singh.Practical toolMariska Fouche, public affairs manager at Pharma Dynamics, highlighted the significance of such a book in helping healthcare practitioners to do their work.“They don’t necessarily have the tools to teach people about healthier eating habits,” she said. “This book is a vital part of the HSF’s preventative toolkit to help tackle the looming heart disease and stroke epidemic in South Africa.”Research by the Medical Research Council and the Chronic Diseases Initiative in Africa using different people across the country, said Fouche, found that CVD patients received limited advice about adapting their diets from doctors at the time of their diagnosis.“They struggled to incorporate the little advice they did get into their everyday lives, meaning that they didn’t make meaningful changes to their diets, which had a negative impact on their management of their condition.”During September, HSF and Pharma Dynamics will be hosting free screenings for heart disease risk factors at shopping centres across the country and those who do get screened will get the book for free.“Screenings will include blood pressure, cholesterol and glucose testing and vital information about cardiovascular disease,” said Fouche.A further 57 000 copies are available at Clicks pharmacy outlets across the country.The Cooking from the Heart website also provides a free e-copy as well as information on where hard copies can be obtained, while a mobile site for smart phones is available at read more

‘England not strong enough in the head’

Article continues below Editors’ Picks Goalkeeper crisis! Walker to the rescue but City sweating on Ederson injury ahead of Liverpool clash Out of his depth! Emery on borrowed time after another abysmal Arsenal display Diving, tactical fouls & the emerging war of words between Guardiola & Klopp Sorry, Cristiano! Pjanic is Juventus’ most important player right now “I will go for Brazil because they look like they are really strong,” Gallas told Goal in response to who will be the favourites for the tournament. “For me, Brazil look very strong in every part of their line-up.”You still have teams like Spain, Germany, France and I am sorry, I don’t say England because it is always the same problem with England.“They are not strong. They are not strong enough in the head. That’s always a problem for them. I remember when we used to play against them and even in the European Championships in 2004, they had a strong, strong squad and they were leading 1-0, three minutes before the end of the game.“But then we won 2-1, when I looked at that squad I thought ‘my God’. Rio Ferdinand, John Terry, Ledley King, Steven Gerrard, for me they were unbelievable, but they didn’t qualify I think for the quarter or semi-final. In the World Cup it was the same thing. This England have the same problem, they are not strong enough.“Maybe [the shirt is too heavy]. Maybe they are also too young. They don’t have a lot of experience. I don’t know why it is so difficult for them to play in the national team. Maybe there is something wrong.“I don’t know if there’s something wrong with the players, I would say maybe yes. But they also have to have the right manager.”Can England improve on past World Cup performances this year?William Gallas has his doubts— Goal (@goal) June 8, 2018Gallas now works as SFR Sport’s Premier League pundit after a successful international career in which he earned 84 caps for Les Bleus and played in a World Cup final.Olivier Giroud Didier Deschamps FranceDidier Deschamps’ side will face Australia, Peru and Denmark in the group stage, but Gallas believes the manager will struggle to select an XI, such is the talent in the country’s squad.“I want to know if France can win that World Cup,” Gallas added. “We have a good opportunity because we have got some great players, some talented players. It is a young squad. We are not afraid of any team, we know we can compete against anyone but when you play a World Cup, it is a different story.“You have a lot of pressure on your shoulders. You are going to realise that you are playing in a World Cup, you can be very emotional and that’s why the players have to understand the World Cup is a completely different competition.”I am sure the France squad can do the right job, the manager is good and he knows how to speak to his players. The players are very clever and intelligent to know what they have to do. That’s what’s very good about that group, you need to have a good relationship with your manager.“The manager knows the World Cup very well because he won it in 1998. He used to be a player, he knows how the players can react so that’s why communication is very, very important. From when he was manager of the national team, he has had good results. The players like him because he understands them.“We have got so many talented players. I wouldn’t want to be in the position of the French national manager because I don’t know how he can make that selection.Kylian Mbappe Russia France Friendly 27032018.jpg“If you look, at the back it is maybe a little bit easier to select players but in terms of midfielders and strikers, to be honest I wouldn’t want to be in his position. All of them are good, we have got so many good wingers and strikers. You don’t know which ones you would have to choose.”France’s neighbours Belgium have a golden generation of their own with the likes of Kevin De Bruyne, Eden Hazard and Romelu Lukaku likely to line up for them in Russia. Gallas believes that Belgium can contend for the trophy but remain outsiders due to their inexperience.“Yes, but Belgium, they let me down for the last competition,” he continued. “Euro 2016, they let me down. They had the same squad, maybe they didn’t have the experience that they had now. They let me down because everyone said Belgium has a great chance to win the Euros and it didn’t happen.“Maybe for this World Cup, they will go to the final, because they have got great players. When you look at the players, all of them play in big clubs. They are unbelievable. When you don’t have experience in the big competitions, then sometimes you can have pressure.“In 2006, we went to the final because we had some experienced players. Zidane was there, Vieira was there, Makelele was there, Henry was there. Barthez was there. For the younger players, it was good, because we didn’t have that pressure on our shoulders. The pressure was on the experienced players.France's Patrice Evra, Thierry Henry, Nicolas Anelka and William Gallas during 2010 World Cup“So it was easy for us to do what we have to do, focus on our job. For example, I was playing with Lilian Thuram so I didn’t feel the pressure on my shoulders, because he was used to playing in many World Cups. For the Belgian squad, how many players have played in the World Cup? I don’t think a lot of players have played in it.“That’s why I said when they have to play against the big teams, maybe it will be a little bit difficult for them.”last_img read more

New laser technique improves neutron yield

first_img Citation: New laser technique improves neutron yield (2017, April 21) retrieved 18 August 2019 from © 2017 (—A team of researchers from several institutions in China has developed a new way to produce neutrons that they claim improves on conventional methods by a factor of 100. In their paper published in the journal Physical Review Letters, the team describes the new method and the results they obtained when testing it. Small-scale nuclear fusion may be a new energy source More information: G. Ren et al. Neutron Generation by Laser-Driven Spherically Convergent Plasma Fusion, Physical Review Letters (2017). DOI: 10.1103/PhysRevLett.118.165001ABSTRACTWe investigate a new laser-driven spherically convergent plasma fusion scheme (SCPF) that can produce thermonuclear neutrons stably and efficiently. In the SCPF scheme, laser beams of nanosecond pulse duration and 1014–1015 W/cm2 intensity uniformly irradiate the fuel layer lined inside a spherical hohlraum. The fuel layer is ablated and heated to expand inwards. Eventually, the hot fuel plasmas converge, collide, merge, and stagnate at the central region, converting most of their kinetic energy to internal energy, forming a thermonuclear fusion fireball. With the assumptions of steady ablation and adiabatic expansion, we theoretically predict the neutron yield Yn to be related to the laser energy EL, the hohlraum radius Rh, and the pulse duration τ through a scaling law of Yn ∝ (EL/Rh1.2τ0.2)2.5. We have done experiments at the ShengGuangIII-prototype facility to demonstrate the principle of the SCPF scheme. Some important implications are discussed. This document is subject to copyright.

For that reason, scientists continue to look for new and better sources. Currently, in one approach, lasers are fired at hydrogen isotope clusters, which causes them to be ionized and to collide, resulting in fusion reactions that release neutrons. Unfortunately, this approach and others are not very efficient. In this new effort, the researchers have taken a new approach to using lasers to produce neutrons—applying the force from the inside rather than the outside.In the new method, a laser is used to heat a deuterium capsule, which fuses deuterium nuclei pairs, resulting in neutron emissions. The method is a form of inertial confinement fusion, but the instability inherent in other techniques has been improved by using what the team terms “spherically convergent plasma fusion.” In this method, the researchers used a spherical capsule covered with a thin layer of gold; the capsule had an inside coating of polystyrene containing an amount of deuterium. The researchers then cut tiny holes in the coating and fired lasers through them, allowing the beams to strike inside the capsule, instigating a fusion reaction and emittance of neutrons. The team used 2 ns 6.3 kJ laser pulses to test their method, and report that they were able to produce approximately 1 billion neutrons for each pulse, which they claim is approximately 100 times better than other methods.The team also suggest that if the target used were deuterium and tritium, it might be possible to boost output by a factor of 1000. They further suggest it might be possible to scale up their method to produce even greater amounts of the subatomic particles. Journal information: Physical Review Letters Explore further Credit: G.

Where theres a will theres a way

first_imgARMED with a vision of publishing books for children, Sameena Shaikh opened her publishing house two months ago. She calls it Aisha after her daughter. Quite recently, the publishing house made a début with 21 New Beginnings, a compilation of true stories of ‘oddity, hope and change’ by Vivek Pandit. Why publishing and why children books particularly?While my two girls were growing up, I realised the vital role books play in the  learning and nurturing of kids. Since then I have been possessed with the idea of a book series for children. Over years, the thought crystalised into a concept – colourful and vivid illustrations to trigger their imagination, small values that could inspire them to be sensitive souls and short stories that could improve their vocabulary and language skills – I finally found the courage to open my own publishing house. Also Read – ‘Playing Jojo was emotionally exhausting’How difficult is it being an indie publisher? May sound clichéd, but I strongly believe ‘where there is a will there is a way’. I never doubted my mission. All I started with were confidence and a creative concept, both have helped my vision blossom into reality. And I know nothing can stop an honest vision, so I never think of the diffculties, just take one step at a time. When it gets tough, I just wait patiently for the cloud to clear.How do you go about choosing your authors? Also Read – Leslie doing new comedy special with NetflixAny work that has depth, clarity, undercurrent of a message, positivity and humour would find space in my publishing house.What are your plans for the future?Innovation and creativity will be the USP of my publishing house. The first book has a new concept – short stories by a known author, plus stories of new writers, all inspired by true incidents (available in Flipkart). My second book would be the beginning of a series for children. Adventues of Donna The Dolphin will have beautiful illustrations and will be filled with the adventures of a Dolphin, which will introduce the children to a whole new world. The series will include a book for age group –  2+ , 5+ and 9+.last_img read more
