N. Zealand part of sunken 'lost continent': scientists

N. Zealand part of sunken 'lost continent': scientistsNew Zealand sits atop a previously unknown continent -- mostly submerged beneath the South Pacific -- that should be recognised with the name Zealandia, scientists said Friday. Researchers said Zealandia was a distinct geological entity and met all the criteria applied to Earth's seven other continents -- elevation above the surrounding area, distinctive geology, a well-defined area and a crust much thicker than that found on the ocean floor. In a paper published in the Geological Society of America's Journal, GSA Today, they said Zealandia measured five million square kilometre (1.9 million square miles) and was 94 percent underwater.

Antarctic Lifeline Visible from Space (Photo)

A thin black line against a sea of white is all that connects Antarctica's Concordia research station to life. Concordia research station is known as the "remotest base on Earth." It's so far from other humans — 372 miles (600 km) from the nearest base, Vostok in Russia — that it's more remote than the International Space Station, according to the ESA. The station is located on the Antarctic Plateau at an elevation of 10,499 feet (3,200 meters).

LPG tunkey project solution in Bangladesh

What is LPG?
Liquefied Petroleum Gas (LPG) is a clean and safe fuel that has a range of properties closest to petrol. It is a by-product of petrol refining and natural gas production. Under slight pressure, LPG turns into liquid form and can then be stored in tanks. 
LPG is a naturally occurring by-product of natural gas extraction (60%) and crude oil refining (40%). It is therefore either used or it is wasted.It is a combination of propane and butane molecules, along with trace amounts of other compounds. 

The key property of LPG is the fact that it is highly calorific gas, which easily condenses even at relatively low pressures and current temperatures. Thank to these properties it can be stored also in small tanks or cylinders.
Another key property of LPG is its easy vaporization and possibility of combustion in gaseous state, when it has even 3x greater calorific value than natural gas and at the same time belongs among most ecological fuels. Pure propane vaporizes at temperatures hig…
