How to protect yourself from the treacherous RIP-currents?

June 22, 2013. At the height of the summer season, which means that each camper on the beach should be aware of the dangers of so-called RIP-currents. This is not nothing but a clash of streams of water, which produces a current, swimmers carries away from the shore. Level RIP-currents that are not visible to humans, and they can be detected when it is too late to fix.

In the United States, starting in May of this year, recorded ten deaths caused by steel treacherous currents. On the beaches of the country's emergency services monitor the dangerous currents and

KEAZ changed the design of their fuses PN2

KEAZ, a Russian manufacturer and supplier of electrical products and low-voltage equipmentFuse series PN2. Now the fuses are available in the new energy-saving housing.

Series Fuses PN2 KEAZ production in the new "energy-saving" is available in the following standard performance:

• PN2-100 for rated currents from 31.5 to 100A

• PN2-250 for rated currents from 80 to 250A

• PN2-400 for rated currents from 200 to 400

• PN2-600 for rated currents from 315 to 630

In addition to all the standard performance Fuse PN2 Factory offers contacts bases.

KEAZ ensure product quality and compliance

Global warming affects the nature of ocean currents

Global warming affects the nature of ocean currents Scientists prove

It is known that the state of the Antarctic deep-sea currents, a dense layer of cold water at a depth of 6000 meters below sea level, depends on the activity of the other currents in the ocean. It is responsible for the timely saturation other layers of ocean water on the planet, which means that it depends on the life of marine ecosystems.

By comparing the measurements carried out in 1970, and including 2012, scientists from Australia and the U.S. found that the volume and density of the

Ocean currents

No one suspected that ocean and sea currents draw a picture on the planet so similar to "The Starry Night" by Van Gogh.

Flow visualization was made by Studio Space Flight Center and NASA shows the current water kruzhashiesya dancing and in the oceans.

The observations were made from 2005 to 2007.

Climate change caused mass migration of tropical fish

Australian scientists say they have strong evidence to the south of the vast migration of tropical fish and other species in decline due to climate change.Climate change is already happening, including the rapid warming in the south-east, and the increase of warm currents in the east of Australia. According to a new report from the south-eastern part of Australia becomes the hot spot because of the increasing southerly winds that increase the intensity of the warm currents.A number of species, including plankton, fish and invertebrates are now found further south due to increased warm currents and a high level of

Strong ocean currents are able to bear killer waves

September 28, 2011

An international team of scientists has discovered that the sea currents increase the likelihood of the killer waves. The results of the study will help to increase the safety of navigation.

It is difficult to come up with greater rigor risk to ships and offshore structures than the killer waves, giant ocean solitary trees, sometimes reaching 30 meters in height. But the worst thing is that no external reasons for their occurrence there. Such a wave can suddenly rise to the tanker, liner, a

By comparing the measurements carried out in 1970, and including 2012, scientists from Australia and the U.S. found that the volume and density of the cold deep currents were reduced to 60%. This suggests that the

Warm ocean currents makes Antarctic melt

Warm ocean currents, to wash the bottom of the ice shelves are called the main reason for the loss of Antarctic ice. An international team of scientists has found that 20 of the 54 examined the ice shelves are melting primarily due to currents. Most are located in West Antarctica, where recently the internal rate of glaciers feeding the ice shelves has increased.

It is water that is responsible for the lion's share of the losses experienced by the Antarctic ice sheet during the study. "We can lose a lot of ice, even

USA: the flow on the Earth are connected with Jupiter?

24.06.2004

 

Scientists have noticed a striking similarity between certain ocean currents on Earth and the bands characteristic of the surface of the gas giant planets like Jupiter. On opening said Boris Galperin of the University of South Florida, and his colleagues from the U.S., Israel and Japan.

Scientists have

Early warning of earthquakes: the predictive power of the radiation

French satellite from orbit recorded a sharp increase in low-frequency radio signals in the area of Haiti is in a whole month before the devastating earthquake of magnitude 7.

The devastating earthquake in Haiti has been one of the biggest disasters of the year — even against the fires in Russia, the oil disaster in the Gulf of Mexico and the eruption of the Icelandic volcano with the unpronounceable name. Some geological aspects of the earthquake, we wrote in the article "The disaster on the island." But above all this, in a polar orbit at an altitude of about 700
