Rabies is an infectious viral disease that is almost always fatal following the onset of clinical symptoms. In up to 99% of cases, domestic dogs are responsible for rabies virus transmission to humans. Yet, rabies can affect both domestic and wild animals.
Parachutes. The parachute was invented by Andre AndrÃ© Jacques (garnerin-1769). 1823 it consisted of a white canvas canopy 23 feet in. Diameter the parachute had 36 ribs and, lines was-semi, rigid making it look like a very large. Umbrella garnerin made his first successful parachute jump Above paris on 22nd, october. 1797s Garnerin failed to include an air vent at the top of his parachute, he oscillated wildly in his descent. However, he landed unhurt half a mile from the balloon's takeoff site. Garnerin therefore became the first man to design a parachute that was capable of slowing a man's fall from a high altitude.
Parachutes can be guided by letting some of the air spill out of the front or back of the parachute. There is also a hole in the middle to allow the parachute to fall vertically. Parachutes can be circular, the traditional shape, or rectangular the shape used for some military and stunt use.he first parachute was designed in 1514 by Leonardo da Vinci in Italy, but it was never used. The first man to make and use one was the Frenchman Andre Garnerin who jumped from a balloon over Paris in 1797.
