Scientists have discovered underwater oases methane

July 17, 2013. During the shooting of the seabed in the autumn of last year, the scientists on board the survey vessel noticed bubbles rising from the depths. Phenomenon has aroused interest marine biologists, and they sent to their place of interest expedition. Here, they found out that the seabed in the form of methane gas bubbles coming out and the vicinity of this space filled with a variety of life forms. A study by researchers revealed that on the ocean floor at depths of up to 1.6 kilometers inhabited by whole colonies of bacteria that are used for life energy of destruction of methane.

Underwater volcanoes erupt differently

Some underwater volcanoes do not erupt and spit out giant blobs of lava, like all well-known gel lamps.Until now, scientists have divided the eruption in two categories: violent (explosive) and effusive. The first type involves adorable kids ejection of ash and rock fragments high into the atmosphere (for example, the eruption of Mount St. Helens in 1980). Second - soft red hot lava flows that irrigate the slopes of the volcano (this, for example, are constantly in Hawaii).Pumice stone to get to the unusual underwater volcano near McAuley in the southwest Pacific, the staff of the University Read more [...]

Local effect of cold leads to frostbite. There are four degrees frostbite. Frostbiting I is characterized by a degree of purple coloration of the skin and swelling. These frostbite heal completely within 3 - 7 days. Sometimes a few days there is a slight peeling on the site and is stored frostbite increased sensitivity to cold. When frostbite II degree bubbles formed by bloody-serous contents, hyperemia and edema of the tissues around. Bubbles on the 1st or 2nd day. Healing occurs in 10-20 days without scarring. May persist long sensitivity to the cold frostbitten areas. When frostbite III Read more [...]

Effect of high barometric pressure

Unlike local resistance to compression of the common uniform barometric pressure is very high. Organism person can carry pressure over 6 MPa without express mechanical damage. Common characteristic effects of increased atmospheric pressure on organism is temporary, reversible changes in the upcoming activities of a number of organs and body systems. In effect on organism high barometric pressure man is found most often in deep diving. When immersed in water, especially in addition to the atmospheric hydrostatic pressure, to increase as the dive. Found that the hydrostatic pressure from atmospheric Read more [...]

Bubbles removed with a cotton swab moistened with 96% alcohol, followed by blurring the base alcohol solutions of methylene blue or brilliant green. Cautery can restrict these bubbles colors without opening them. Skin Read more [...]

Pearl (air-gas) bath

"Pearl" (air-gas) bath is prepared by passing air, compressor pumped through tubes with small holes, reinforced in the lattice, which lies at the bottom of the tub. The air coming out of the holes under pressure, causing swirling water. Bath got its name because the air bubbles, shimmering in the water, reminiscent of pearls. The presence of large bubbles increases thermal and mechanical stimulation of the nerve endings in the skin, but the hydrostatic pressure decreases. These baths are easier to carry than fresh, the water temperature is 36 ° C. They have a tonic, and sometimes Read more [...]
