In the processing of concrete help Lightning

In the processing of concrete help Lightning Facts

Scientists working with the Fraunhofer Institute for Building Physics, claim that they have found a way to use lightning to simplify the processing of concrete waste remaining from the collapsed buildings.

As they explain, the processing of concrete is not as simple as it seems at first glance. And while the scientists had not thought to use the zipper for crushing concrete debris, the only possible way to re-use has been split and use as a base layer for the building of earth roads or building foundations. The new technology

Debris after the March tsunami soon reached the island of Hawaii

Debris after the March tsunami soon reached the island of Hawaii Natural Disasters

The wreckage and debris washed into the sea tsunami following the March earthquake in Japan have increased by several million tons of the total amount of garbage in the Pacific Ocean. According to preliminary estimates the debris should reach the coast of California in 2013, but the first encounter with the U.S. territories will be much sooner. Scientists from the National Oceanic and Atmospheric Administration U.S. claim that partially submerged wreckage came close to the north-west coast of Hawaii in the winter 2011-2012.

Almost a year has passed since the day when the earthquake happened in Japan, Tohoku, and in the Pacific Ocean is still floating debris, carried away from the shore of the tsunami waves. Debris weighing about 20 tons with sea Kuroshio Current, enveloping Asia around 35 ° N, are moving to the east and covers an area of more than 3,600 km long and 1,800 km wide.

High levels of CO2 as a cause of accidents in space

High levels of CO2 as a cause of accidents in space Facts

Increasing levels of carbon dioxide in the Earth's upper atmosphere can lead to a gradual cooling of a compressed layer thermosphere. Becomes more viscous, thermosphere can change greatly orbit satellite launched. They, in turn, begin to turn closer to the planet.

Layers of Earth's atmosphere To continue on the set from Earth orbit satellites may require special external drives. In addition, they would face near-Earth space debris orbit which is already broken due to changes in the thermosphere, which involved carbon dioxide. As the analysis of

In the depths of the Arctic has increased the number of plastic waste

In the depths of the Arctic has increased the number of plastic waste Facts

Conducting monitoring of the deep seas of the Arctic, the scientists found that contamination with plastic and other debris in them exceeds the level of contamination of the coastal marine canyon near the Portuguese capital, Lisbon. Experts gave this conclusion on the basis of 2100 photos taken at the bottom of the Arctic Fram Strait around deep observatory Hauzgarten owned Wegener Institute. Strait is a sea route connecting the Greenland and the Norwegian island of Spitsbergen. Photographs were taken in 2002, 2004, 2007, 2008 and 2011.

Dust storm in Pakistan

Dust storm in Pakistan, Natural disasters

A strong sandstorm hit many coastal districts of Sindh and Balochistan. Visibility on the road is no more than 200 meters in some places it dropped to 50 meters. The difficulties experienced with landing aircraft on international and domestic routes from several South-Pakistani airports (Sukkur, Nawabshah, Quetta and Gavadar). Many of them just turns around and flew back or landing at airports in other counties. For reasons of security at the airport in Karachi to improved weather conditions, thousands of passengers have been detained by public and private airlines.
