Players of Cricket

A team contains an eleven players. Depending on his or her most important skills, a player may be classified as a specialist batsman or bowler. A balanced team generally has five or six expert batsmen and four or five expert bowlers. Teams nearly for all time include a specialist wicket-keeper because of the importance of this fielding position. Each team is headed by a captain, who is in charge for making strategic decisions such as determining the batting order, the placement of fielders and the rotation of bowlers.

A player who excels in both batting and bowling is called as an all-rounder. One who excels as a batsman and wicket-keeper is known as a "wicket-keeper/batsman", sometimes regarded as a kind of all-rounder. True all-rounders are rare; most players focal point on either batting or bowling skills.

One-day Match & Draw Match
If the team batting last is all out, and in cooperation sides have scored the same number of runs, then the match is a tie; this result is reasonably rare in matches of two innings a side. In the traditional form of the game, if the time allotted for the match expires before either side can win, then the game is declared a draw.

If the match has only a single innings for each side, then a maximum number of deliveries for every innings is often imposed. Such a match is called a "limited overs" or "one-day" match, and the side scoring more runs wins in spite of of the number of wickets lost, so that a draw cannot occur. If this kind of match is for the moment interrupted by bad weather, then a complex mathematical formula, known as the Duckworth-Lewis method after its developers, is often used to recalculate a new aim score. A one-day match can also be declared a "no-result" if less than a previously agreed number of overs have been bowled by either team, in circumstances that make normal recommencement of play impossible; for example, wet weather.

Results of cricket

If the team that bats last is all out previous to it has reached the total required to win, it is said to have "lost by n runs" (where n is the difference between the number of runs scored by the teams). If the team that bats very last scores enough runs to win, it is said to have "won by n wickets", where n is the number of wickets left to fall. For occurrence a team that passes its opponents' score having only lost six wickets would have won "by four wickets".

In a two-innings-a-side match, one team's combined first and second innings total may be less than the another side's first innings total. The team with the greater score is then said to have won by an innings and n runs, and does not require to bat again: n is the difference between the two teams' aggregate scores.

Overview of Cricket


The aim of the batting team is to score as several runs as possible. A run is scored when both batsmen effectively move to their respective opposite ends of the pitch. (The batsmen will usually only attempt to score runs after the striker has hit the ball, but this is not required by the rules—the batsmen can attempt runs at any time after the ball has been bowled.) Runs are also scored if the batsman hits the ball to the boundary of the before a live audience area (this scores six runs if the ball crosses the boundary without having touched the ground, or four runs otherwise), or if the bowler commits some technical contravention like bowling the ball out of reach of the batsman.[citation needed]

The aim of the bowler's side is to get each batsman out (this is called a "taking a wicket", or a "dismissal"). Dismissals are achieved in a different ways. The most straight way is for the bowler to bowl the ball so that the batsman misses it and it hits the stumps, dislodging a bail. While the batsmen are attempting a run, the fielders may dismiss either batsman by using the ball to beat the bails off the set of stumps to which the batsman is closest before he has grounded himself or his bat in the crease. Other ways for the fielding side to dismiss a batsman contain catching the ball off the bat before it touches the ground, or having the batsman adjudged "leg before wicket" (abbreviated "L.B.W." or "lbw") if the ball strikes the batsman's body and would have gone on to hit the wicket. Once the batsmen are not attempting to achieve any more runs, the ball is "dead", and is bowled again (each attempt at bowling the ball is a "ball" or a "delivery").

Cricket

Cricket is a bat-and-ball sport contest by two teams, regularly of eleven players each.A cricket match is played on a grass ground, roughly oval in shape, in the centre of which is a flat strip of ground 22 yards (20.12 m) long, called a cricket pitch. A wicket, regularly made of wood, is placed at each end of the pitch.

The bowler, a player from the fielding team, hurls a hard, fist-sized cricket ball from the surrounding area of one wicket towards the other. The ball usually bounces once before attainment the batsman, a player from the opposing team. In boldness of the wicket, the batsman plays the ball with a wooden cricket bat. Meanwhile, the other members of the bowler's team stand in different positions around the field as fielders, players who retrieve the ball in an effort to stop the batsman scoring, and if possible to get him or her out. The batsman—if he or she does not get out—may run between the wickets, exchanging ends with a second batsman (the "non-striker"), who has been coming up near the bowler's wicket. Each completed exchange of ends scores one run. Runs are also scored if the batsman hits the ball to the boundary of the in performance area. The match is won by the team that team must took more runs.

Krill fishery

Krill fishery is the profitable fishery of krill, small shrimp-like marine animals that live in the oceans world-wide. Estimates for how much krill there is vary wildly, depending on the methodology used. They range from 125–725 million tones of biomass globally. The total global harvest of krill from all fisheries amounts to 150 – 200,000 tones annually, mainly Antarctic krill (Euphausia superb) and North Pacific krill (E. Pacifica).

Krill are rich in protein (40% or more of dry weight) and lipids (about 20% in E. superb). Their exoskeleton amounts to some 2% of dry weight of chitin. They also contain traces of a wide array of hydrolytic enzymes such as proteases, carbohydrates, nucleases and phospholipids, which are intense in the digestive gland in the cephalothoraxes of the krill.

Pollen

Pollen is a fine to coarse powder consisting of micro gametophytes (pollen grains), which create the male gametes (sperm cells) of seed plants. The pollen grains with its hard coat protect the sperm cells throughout the process of their movement between the stamens of the flower to the pistil of the next flower.

Earth's atmosphere

Earth's atmosphere is a layer of gases surrounding the planet Earth and retain by the Earth's gravity. It contains roughly (by molar content/volume) 78% nitrogen, 20.95% oxygen, 0.93% argon, 0.038% carbon dioxide; trace amounts of other gases, and a changeable amount (average around 1%) of water vapor. This mixture of gases is usually known as air. The atmosphere protects life on Earth by captivating ultraviolet solar radiation and reducing temperature extremes between day and night.

There is no exact border between the atmosphere and outer space, it slowly becomes thinner and fades into liberty. Three quarters of the atmosphere's mass is within 11 km of the terrestrial surface. In the United States, people who travel above a height of 80.5 km (50 statute miles) are selected astronauts. An altitude of 120 km (400,000 ft) marks the boundary where atmospheric property becomes obvious during re-entry. The Kármán line, at 100 km (328,000 ft), is also often regarded as the boundary between atmosphere and outer space.

Dance

Dance means in Old French dancier, perhaps from Frankish generally refers to human movement also used as a form of expression or presented in a social, spiritual or performance setting.

Dance also is used to explain methods of non-verbal communication (see body language) between humans or animals (bee dance, mating dance), motion in inanimate objects (the leaves danced in the wind), and certain musical forms or genres.

Choreography is the art of making dances, and the human being who does this is called a choreographer.

Definitions of what constitutes dance are dependent on social, cultural, visual, artistic and moral constraints and variety from functional movement (such as folk dance) to codified, virtuoso techniques such as ballet. Dance disciplines live in sports such as gymnastics, figure skating, and synchronized swimming and martial arts kata are often compare to dance.
