Checking (ice hockey)

Checking in ice hockey is any one of a number of defensive techniques, aimed at disrupting an opponent with possession of the puck, or separating them from the puck entirely. It is usually not a penalty.

Types

Rules on checking

Illegal checking

Charging, hitting from behind and boarding are examples of illegal hits. Charging occurs when a player takes three or more strides going into the check, and sometimes includes leaving the feet to deliver the hit. Boarding is when a check violently throws a defenseless player into the boards. Due to their dangerous nature and increased likelihood of causing serious injury, these hits can have penalties ranging from a minor two-minute penalty to a major and game misconduct, along with a $100 fine in the NHL. In women's ice hockey, any body checking is a penalty and is also not allowed in leagues with young children. Men's amateur leagues typically allow checking unless stipulated otherwise in league rules. Some intramural university leagues do not permit body checking, in order to avoid injury and incidents of fighting. "Leaning" against opponents is an alternative to body checking but can be penalized for holding if abused. Many studies have been done regarding injuries in hockey that have caused stricter rule enforcement in the past few years. There have been increases in number of concussions and other serious injuries that brought about these changes.

Betting in poker

In the game of poker, the play largely centers on the act of betting, and as such, a protocol has been developed to speed up play, lessen confusion, and increase security while playing. Different games are played using different types of bets, and small variations in etiquette exist between cardrooms, but for the most part the following rules and protocol are observed by the majority of poker players.

Procedure

Players in a poker game act in turn, in clockwise rotation (acting out of turn can negatively affect other players). When it is a player's turn to act, the first verbal declaration or action she takes binds her to her choice of action; this rule prevents a player from changing her action after seeing how other players react to her initial, verbal action.

Until the first bet is made each player in turn may "check," which is to not place a bet, or "open," which is to make the first bet. After the first bet each player may "fold," which is to drop out of the hand losing any bets they have already made; "call," which is to match the highest bet so far made; or "raise," which is to increase the previous high bet.

Domain wall

A domain wall is a type of topological soliton that occurs whenever a discrete symmetry is spontaneously broken. Domain walls also sometimes called kinks in analogy with closely related kink solution of the sine-Gordon model. Unstable domain walls can also appear if spontaneously broken discrete symmetry is approximate and there is the metastable vacuum.

A domain (hyper volume) is extended in three spatial dimensions and one time dimension. A domain wall is the boundary between two neighboring domains. Thus a domain wall is extended in two spatial dimensions and one time dimension.

Important examples are:

Besides these important cases similar solitons appear in wide spectrum of the models. Here are other examples:

Domain (band)

Domain is a German power metal band.

History

1986–1992

Domain first impressed fans of melodic metal back in the 1980s with their first works, "Lost In The City" (still under the old band name Kingdom), "Before The Storm" and "Crack in The Wall", as well as with their hit songs such as 'Lost In The City' and ‚ 'I Don’t Wanna Die'. Single "Heart Of Stone was a title song of german mini-serial "Bastard".

2000–2006

But it was their next albums, "One Million Lightyears From Home" (2001), "The Artefact" (2002) and "The Sixth Dimension" (2003) as well as a successful tour with the rock legends, Glenn Hughes and Joe Lynn Turner (HTP) that secured the quintet a place in the European Melodic Metal scene. With a harder edged sound, Domain still had a good following. And that was when the career of the guitarist Axel "Ironfinger" Ritt (Grave Digger), ex-vocalist Carsten Lizard Schulz (Evidence One et al.), and the long-term band mates keyboarder Erdmann Lange, ex-bass player Jochen Mayer (Boysvoice, Demon Drive, Casanova) and the ex-drummer Stefan Köllner really began…
