Parachute

By creating drag, a parachute is a soft fabric device used to slow the motion of an object through an atmosphere. Parachutes are usually used to slow the descent of a person or object to Earth or another celestial body within an atmosphere. Occasionally Drogue parachutes are also used to aid horizontal deceleration of a vehicle. From the French words para, protect or shield, and chute, the fall, parachute the word came. "Fall protection" is the real meaning of parachute. Recent parachutes are classified as semi-rigid wings, are quite maneuverable, and can facilitate a controlled descent similar to that of a glider.

Now parachutes are constructed from more durable woven nylon fabric, sometimes coated with silicone to improve performance and consistency over time, but it once made from silk. Manufacturers of parachutes switched to low-stretch materials like Dacron or zero-stretch materials like Spectra, Kevlar, Vectran and high-modulus aramids When the square parachutes were introduced.

Culture

Culture usually refers to patterns of human being activity and the representative structures that give such activity meaning. Different definitions of "culture" reflect special theoretical bases for considerate for evaluating, human activity. Most general, the term culture denotes entire product of an individual, group or society of smart beings. It includes technology, art, science, with moral systems and the feature behaviors and practice of the selected intelligent entities. In particular, it has exact more detailed meanings in different domains of human activities.

Many people nowadays have a thought of "culture" that developed in Europe through the 18th and early 19th centuries. This view of culture reflected inequalities within European societies, and between European powers and their colonies around the world. It identifies "culture" with "society" and contrasts it with "nature." According to this method of view, one can organize some countries as more civilized than others, and some people as more cultured than others.

River

A river is a natural waterway, which moves water diagonally the land from upper to lower elevations, and is a main part of the water cycle. The water within a river is generally from rain through surface runoff and release of stored water in natural reservoirs, such as groundwater.

The beginning of a mountain river from their resource, all rivers run downhill, naturally terminating in the sea or in a lake, during a flowing together. In dry areas rivers sometimes finish by losing water to evaporation. River water may also gain access to the soil or pervious rock, where it becomes groundwater. Extreme abstraction of water for use in industry, irrigation, etc., can also source a river to dry before reaching its natural boundary.

Bipedal Animals

Bipedal group has evolved a number of times other than in humans, mostly among the vertebrates. The most obvious example of bipedal Movement is among the birds and their ancestors the theropod dinosaurs. All dinosaurs are supposed to be descended from a fully bipedal Ancestor, perhaps similar to Eoraptor. Indeed, among their descendants, the larger flightless birds, the ratites, such as the ostrich, perhaps .
Epitomize the capacity to move bipedally, able to reach speeds of up to 65 km/h. likewise many theropod dinosaurs, especially the maniraptors, are supposed to have been able to move at similar speeds. Bipedal movement also re-evolved in a number of other dinosaur lineages such as the iguanodons. Bipealism has also evolved in the crocodilian line, a sister group to the dinosaurs and birds - a crocodile relative from the Triassic, Effigia okeeffeae, was believed to be bipedal. Penguins are attractive birds with regard to bipedality as they tend to hold their bodies upright, rather than horizontal as in other birds.
