Should only swim along the coast and always under constant surveillance, so that time could come for help – to avoid serious mischief in the water: swim for swimmers, grabbing them by their legs, "sink" to file false signals for help, etc. – not leave the water babies. They may stumble and fall, awash with water or get into the pit. Unfortunately, not uncommon for young children drown in a bathtub, abandoned by parents, older "just for a moment" – not swim for restrictive signs, because they restrict the water area with proven bottom, a certain depth, there is guaranteed no swirls, etc. Do not have to sail far from shore or swim in the water dispute. Prove their ability to swim can swim several times the same distance near the coast – not to swim close to passing ships, boats and motor boats.

summer LIFE-SAVING and their use. terms of use Individual life-saving. By the summer saving appliances include: lifesaver. There are two types: cork and foam. Mass range of cork – to 7 kg, diameter (external) – 750 mm foam plastic – up to 4,5 kg diameter – 750 mm.

By a circle with four sides fixed rail. To circle was clearly visible, its painted in bright orange. rules of submission lifesaver. Holding one hand on the lifeline, the second for Leer, make two or three circular sweep straight arm at shoulder height and drop it flat on a drowning man, he fell to the right or left of him at a distance of 0.5 – 1m.

'Using data from the spacecraft Voyager, we found a strong magnetic field just outside the solar system' – explains senior author Merav Opher (Merav Opher), visiting scholar at the Department of heliophysics nasa from George Mason University (George Mason). 'This magnetic field keeps the interstellar cloud from the collapse, and explains the existing long been a riddle of his existence. " Top: Voyager flies through the outer limits of the heliosphere on the way to interstellar space. Strong magnetic field, which Ofer and other authors have reported the release of Nature of 24 December 2009, outlined in yellow. Copyright in a photograph in 2009, the American Museum of Natural History. This discovery is undoubted importance for the future, when the solar system, eventually collide with other like clouds in our arm of the Milky Way galaxy. Astronomers call the clouds where we are now entering, Local interstellar cloud (LMO) or more briefly 'Local Pooh'. The cloud has a width of about 30 light years and consists of a patchy mixture of hydrogen and helium with a temperature of 6,000 C.

Actually existing puzzle Pooh should be somehow linked to its environment. Occurred near the Pooh, some 10 million years ago, an explosion of supernovae creates a cluster of giant gas bubble at a temperature of several million degrees. Streams gas from the supernova ejected under high pressure, all surrounded by a cloud entirely and would have to break up or disperse it. 'The observed temperature and density of the local clouds do not provide sufficient pressure able to resist 'crushing action' of hot gas surrounding the cloud '- says Ofer (Opher).
