Fossil shows pregnant momma sea monster with developing embryo

A fish-eating reptile called Dinocephalosaurus, which lived about 245 million years ago during the Triassic Period, is pictured in this artist's reconstruction handout imageBy Will Dunham WASHINGTON (Reuters) - An extraordinary fossil unearthed in southwestern China shows a pregnant long-necked marine reptile that lived millions of years before the dinosaurs with its developing embryo, indicating this creature gave birth to live babies rather than laying eggs. Scientists on Tuesday said the fossil of the unusual fish-eating reptile called Dinocephalosaurus, which lived about 245 million years ago during the Triassic Period, changes the understanding of the evolution of vertebrate reproductive systems. Dinocephalosaurus is the first member of a broad vertebrate group called archosauromorphs that includes birds, crocodilians, dinosaurs and extinct flying reptiles known as pterosaurs known to give birth this way, paleontologist Jun Liu of China's Hefei University of Technology said.

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…
