Extreme helicopter operations
As Russia prepares for the 2014 Winter Olympics, big changes are taking place in the southern city of Sochi as the Olympic village is built from the ground up. Dozens of world-class sport complexes are under construction, along with hundreds of kilometres of new roads, tunnels and bridges. And all of this is being done in the mountainous region of the Caucasus. Mast lighting is being installed on the “Russian hills” where the Olympic ski jump complex is located. It is impossible however, to get heavy ground equipment to such heights, so workers must use helicopters instead. Between the peaks of Mount Aibga the wind is extremely unpredictable and constantly changes direction, which complicates things further. The pilots have to install 50-foot mast lighting in difficult to access areas, but not every helicopter is capable of hovering over an installation point for several minutes. The Kam...
Medical technologies — blood donation service
Blood – it’s part of our body’s internal defence system, reacting to any invasion from outside. It regulates our body temperature and delivers substances we need to all of our organs. The average adult body has between five and six litres of blood flowing through it, and if, due to an accident, this volume were to decrease by just a third, the person would be in real danger of dying. Fortunately, there is a whole medical system dedicated to helping people survive such dire situations and most anyone can help. All you have to do is visit a donation centre in order to give blood. Every year donors help provide others with another chance at life, saving thousands all over the world with their donation.

The Tyumen cryobank — cold in the service of science
Nowadays medicine and the biological sciences would be nothing without cryogenic technologies – what is known among specialists as the freezing of cellular and genetic material. Such specimens are then preserved in cryobanks – low-temperature refrigerators which maintain these chilly temperatures with the help of liquid nitrogen. A cryobank is not merely a negative 200-degree refrigerator – it is an advanced piece of equipment developed with the help of complex high technologies. There are only about 200 of them in the whole world and one of them is in the Russian city of Tyumen. There the cryobank is used not only to store biomaterial, but as the basis for scientific research in the field of biotechnology – and scientists in Tyumen have already succeeded in making significant discoveries.
