Eventhough parachutes seem to have been used in China since the 1100s and that Leonardo da Vinci of Italy had invented devices similar to parachutes nowadays, worldwide skydivers state that the French inventor André-Jacques Garnerin is the one to make the first parachute. In 1797 he jumped from a balloon over Paris using a parachute and kept on making other jumps in France and also in England.

In World War I , that is between 1914 and 1918, the military began using parachutes in their missions

The introduction of Western cultural values, which had flooded Japan by the late nineteenth century, led to a dichotomy between traditional values and attempts to duplicate and assimilate a variety of clashing new ideas

Japanese aesthetics provide a key to understanding artistic works perceivably different from those coming from Western traditions.

Within the East Asian artistic tradition, China has been the acknowledged teacher and Japan the devoted student.

The Chesapeake Bay, forexample, has been polluted with the nutrients nitrogen andphosphorus and with excess sediment caused, in part, by urbanrunoff. The excess nutrients cause algae blooms that blocksunlight from reaching bay grasses-which are a source of food,shelter, and nursery grounds for many aquatic species.

In aneffort to control nutrient pollution in the Chesapeake Bay, theExecutive Council of the Chesapeake Bay Program" established agoal to reduce the nitrogen and phosphorus entering theChesapeake Bay by 40 percent, including through control of runofffrom urban areas.

Leonardo da Vinci designed a flying machine in the 15th century, and by the 19th century men were airborne in hot-air balloons, gliders, and huge kites.

And so, at the end of the 19th century, enthusiasts around the world joined in the race to invent the first flying machine.

Chaining up a dog and forcing it to go without food and water in the name of art is a surefire way of making yourself unpopular with animal lovers. The furore created by Damien Hirst's pickled sheep and Tracey Emin's dirty bed pales into insignificance against the international outrage Guillermo 'Habacuc' Vargas has unleashed. The Costa Rican has been called an animal abuser, killer and worse over claims that a stray dog called Natividad died of starvation after he displayed it at an exhibition last year at the Códice Gallery in Managua, Nicaragua. Vargas tethered the animal without food and water under the words 'Eres Lo Que Lees' - 'You Are What You Read' - made out of dog biscuits while he played the Sandinista anthem backwards and set 175 pieces of crack cocaine alight in a massive incense burner. More than a million people have signed an online petition urging organisers of this year's event to stop Vargas taking part. Vargas, 32, said he wanted to test the public's reaction, and insisted none of the exhibition visitors intervened to stop the animal's suffering. He refused to say whether the animal had survived the show, but said he had received dozens of death threats. Juanita Bermúdez, director of the Códice Gallery, insisted Natividad escaped after just one day. She said: 'It was untied all the time except for the three hours the exhibition lasted and it was fed regularly with dog food Habacuc himself brought in.'

One unique feature of bats is their modified forelimbs, which support a wing membrane (patagium). The basic elements of the mammalian limb are present in bats, although the relative sizes of most bones and muscles differ from those of nonflying mammals. The most elongated parts of the limb are those of the hand (metacarpal bones) and fingers (phalanges). The primary functions of these bones in bats is to provide support for the patagium and control its movements.

Numerous blood vessels and nerves are present throughout the wing membrane. Bats also have five unique muscles present in the patagium, and use additional muscles in the chest and back to move the wings up and down.

The most obvious difference between bird wings and those of bats is that bird wings are made of feathers, not a skin membrane. Birds have an elongated arm, but do not have elongated fingers like bats. Additionally, the muscles used in both the upstroke and downstroke are found in the chest of birds, while the upstroke muscles are on the back in bats (Fenton, 1983).

Pollution at the nation’s 3,500 ocean, lake and bay beaches resulted in more than 25,000 closing or swimming advisory days last year, 28 percent more than in 2005, and the highest number in the 17 years that records have been kept, according to a new federal report released Tuesday.

largest and most productive estuaries in North America.  

However, in 1993 the EVOS Trustee Council funded an additional survey that estimated 7 km of shoreline were still contaminated with subsurface oil.

Because a significant survey of Prince William Sound had not been conducted since 1993 and the cumulative extent of the remaining oil was unknown, concerns were generated by the public and scientific communities about the oil’s possible continuing effects on humans and fauna potentially exposed to the oil directly or indirectly.
