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.
The oldest parachute design appears in an anonymous manuscript from 1470s Renaissance Italy (British Museum Add. MSS 34,113, fol. 200v), showing a free-hanging man clutching a cross bar frame attached to a conical canopy. As a safety measure, four straps run from the ends of the rods to a waist belt.
