Sarus Crane

The Sarus Crane is a occupant propagation bird in northern India, Nepal, Southeast Asia and Queensland, Australia. It used to be found on accasion in pakistan, but has not been found silence the late 1980's. It is the world's tallest flying bird.

This is a very huge crane, 156cm in length, which is found in freshwater marshes and plains. It nests on the ground laying two to three eggs in a bulky nest. Unlike many cranes that make long migrations the sarus crane does not, meaning it cans expent the energy to raise both chicks. Both the male and female take turns sitting on the nest, and the male is the main guardian.

Adults are grey with a nude red head and white crown and a long dark pointed bill. In flight, the long neck is reserved straight, unlike herons, and the black wing tips can be seen; their long red or pink legs trail at the back them.

Sexes are similar, but young flora and fauna are duller and browner. The Indian, Southeast Asian and Australian species differ mainly in plumage shade. There are some slight size differences, but on average the male is larger then the female, and the birds are six feet tall with an eight foot wingspan.

These extroverted birds forage while walking in thin water or in fields, sometimes probing with their long bills. They are omnivorous, eating insects, marine plants and animals, crustaceans, seeds and berries, small vertebrates, and invertebrates.

Sitka Spruce

The Sitka Spruce (Picea sitchensis) is a large evergreen tree growing to 50-70 m tall, exceptionally to 96 m tall, and with a trunk diameter of up to 5 m. It is by far the main species of spruce, and the third tallest tree species in the world (after Coast Redwood and Coast Douglas-fir).Young Sitka Spruce in a forestry plantation in Britain The bark is thin and scaly, flaking off in small circular plates 5-20 cm across. The crown is broad conic in young trees, becoming cylindric in older trees; old trees may have no branches in the lowest 30-40 m. The shoots are very pale buff-brown, almost white, and glabrous (hairless) but with prominent pulvini. The leaves are stiff, sharp and needle-like, 15-25 mm long, flattened in cross-section, dark glaucous blue-green above with two or three thin lines of stomata, and blue-white below with two dense bands of stomata.

The cones are pendulous, slender cylindrical, 5-11 cm long and 2 cm broad when closed, opening to 3 cm broad. They have thin, flexible scales 15-20 mm long; the bracts just above the scales are the longest of any spruce, occasionally just exserted and visible on the closed cones. They are green or reddish, maturing pale brown 5-7 months after pollination. The seeds are black, 3 mm long, with a slender, 7-9 mm long pale brown wing.

Airline

An airline is an association that specializes in provided that designed air transport services to passengers and/or for cargo; although some airlines do offer chartered flight services as well. Airlines lease or own their aircraft with which to supply these services and may form partnerships or alliances with other airlines for reasons of mutual benefit.

Industry overview

An airline is an association that specializes in provided that designed air transport services to passengers and/or for cargo; although some airlines do offer chartered flight services as well. Airlines lease or own their aircraft with which to supply these services and may form partnerships or alliances with other airlines for reasons of mutual benefit.


The headquarters of Air India is Mumbai.The universal replica of rights has gone from government owned or supported to self-determining, for-profit public companies. This occurs as regulators permit greater freedom, in steps that are usually decades not together. This pattern has not been complete for all airlines in all regions.
The command for air travel services is imitative demand. That is, it depends on other things: business needs for cargo shipments, business passenger demand, and leisure passenger demand, all prejudiced by macroeconomic activity in the markets under learn. These patterns are dreadfully serial, and often day-of-week, time-of-day, and even directionally variable.
The business is returning. Four or five years of poor production are followed by five or six years of slowly improving good performance. But efficiency in the good years is normally low, in the range of 2-3% net profit after interest and tax. It is in this time that airlines begin paying for new generations of airplanes and other service upgrades they planned to respond to the increased demand. Since 1980, the industry as a whole has not even earned back the cost of capital during the best of times. Equally, in bad times losses can be radically inferior.

Multitrack recording

Multitrack recording is a method of sound recording that allows for the recording of multiple sound sources, whether at the same time or at different times. This is probably the most common technique of recording popular music: Musicians or singers can be recorded independently, then these performances can be edited together to create a cohesive result. It is also called 'multitracking' or just 'tracking' for short.Multitrack recording devices are available with varying capacities. When recording a segment of audio, which is also known as a track, audio engineers and musicians may select which track or tracks on the device will be used.

Pace Car

A pace car has been used to start the Indianapolis 500 since 1911. The first pace car was a Stoddard-Dayton driven by Carl G Fisher. Other car and motorcycle races have also used pace cars.The purpose of a pace car is to help provide an organized running start to the race.The racecars follow the pace car around the track, maintaining their assigned pole positions.The exact details can vary, but characteristically, there is one "parade lap" at a relatively low speed. This is followed by a much faster lap that straight leads to the formal start of the race, as the pace car turns off the track into the pit area.Many years, the driver of the pace car is someone associated to car racing or the automotive industry, such as the dealer that provided the car, an executive of a US automaker, or a retired racecar driver. However, particularly in recent years, the driver may be a celebrity; recently comedian and talk show host Jay Leno , and actor Anthony Edwards have driven the Indy pace car. Colin Powell was selected to drive the pace car for the 2005 event.

Acacia

Acacia is a kind of shrubs and trees of Gondwanian origin belonging to the subfamily Mimosoideae of the Pea Family Fabaceae, first described from Africa by Linnaeus in 1773.
There are approximately 1300 species worldwide: about 950 of them being native to Australia, while the remainder are increase around the dry tropical to warm-temperate regions of both hemispheres, including Africa, southern Asia, and the Americas. The genus Acacia though is not monophyletic. This has led to the breaking up of this genus in 5 new genera. This has been discussed in List of Acacia species.
The northernmost species is Acacia greggii (Catclaw Acacia), reaching 37°10' N in southern Utah in the United States; the southernmost are Acacia dealbata (Silver Wattle), Acacia longifolia (Coast Wattle or Sydney Golden Wattle), Acacia mearnsii (Black Wattle), and Acacia melanoxylon (Blackwood), reaching 43°30' S in Tasmania, Australia, while Acacia caven (Espinillo Negro) reaches nearly as far south in northeastern Chubut Province, Argentina. Australian species are typically called wattles, while African and American species tend to be known as acacias.
