Ice hockey

Ice hockey is a contact team sport played on ice, usually in a rink, in which two teams of skaters use their sticks to shoot a vulcanized rubber puck into their opponent's net to score points. Ice hockey teams usually consist of four lines of three forwards, three pairs of defencemen, and two goaltenders. Normally, each team has five players who skate up and down the ice trying to take the puck and score a goal against the opposing team.

A fast-paced, physical sport, hockey is most popular in areas of North America (particularly Canada and the northern United States) and northern and western Europe. In North America, the National Hockey League (NHL) is the highest level for men's hockey and the most popular. The Kontinental Hockey League (KHL) is the highest league in Russia and much of Eastern Europe. Ice hockey is the official national winter sport of Canada, where the game enjoys immense popularity. The International Ice Hockey Federation (IIHF) is the formal governing body for international ice hockey. The IIHF manages international tournaments and maintains the IIHF World Ranking. Worldwide, there are ice hockey federations in 74 countries.

The Hockey Players (film)

The Hockey Players (original title: Khokkeisty) (Russian: Хоккеисты) is a 1964 Soviet sports drama film written by Yury Trifonov and directed by Raphael Goldin. It had English release in 1965 under the title The Hockey Players, Finnish release as Mestarit, and East German release as Eishockeyspieler.

Plot

Thirty-year captain of the Rockets hockey team, Anatoly Duganov (Vyacheslav Shalevich), famous and experienced player decides to fight for the sport longevity of the old men as he tries to prove that it is still too early to retire. But in sports, including hockey, for a long time there is a certain stereotype: in 16 years is considered to be more junior player, at 18 years young player in the adult team, and in 25 years - is already a veteran. Acutely experiencing a quarrel with my girlfriend Maya (Elza Lezhdey), Duganov seeking participation in the decisive final match between the two strongest teams - and seek victory team.

Cha (Korean surname)

Cha is an relatively uncommon family name in Korea. The Yeonan Cha clan is the only clan. The founding ancestor was Cha Hyo-jeon, son of Ryoo Cha-dal (류차달) (10th century AD). Most of the clan's members live in Gyeongsang, Hwanghae, and P'yŏngan provinces. In South Korea in 2000, there were 180,589 people named Cha. It is derived from the Chinese surname Che, written in the same hanja.

Tournament (graph theory)

A tournament is a directed graph (digraph) obtained by assigning a direction for each edge in an undirected complete graph. That is, it is an orientation of a complete graph, or equivalently a directed graph in which every pair of distinct vertices is connected by a single directed edge.

Many of the important properties of tournaments were first investigated by Landau in order to model dominance relations in flocks of chickens. Current applications of tournaments include the study of voting theory and social choice theory among other things. The name tournament originates from such a graph's interpretation as the outcome of a round-robin tournament in which every player encounters every other player exactly once, and in which no draws occur. In the tournament digraph, the vertices correspond to the players. The edge between each pair of players is oriented from the winner to the loser. If player beats player , then it is said that dominates .

Paths and cycles

Any tournament on a finite number of vertices contains a Hamiltonian path, i.e., directed path on all vertices (Rédei 1934). This is easily shown by induction on : suppose that the statement holds for , and consider any tournament on vertices. Choose a vertex of and consider a directed path in . Now let be maximal such that for every there is a directed edge from to .

MEN1

Menin is a protein that in humans is encoded by the MEN1 gene. Menin is a putative tumor suppressor associated with multiple endocrine neoplasia type 1 (MEN-1 syndrome).

In vitro studies have shown that menin is localized to the nucleus, possesses two functional nuclear localization signals, and inhibits transcriptional activation by JunD. However, the function of this protein is not known. Two messages have been detected on northern blots but the larger message has not been characterized. Two variants of the shorter transcript have been identified where alternative splicing affects the coding sequence. Five variants where alternative splicing takes place in the 5' UTR have also been identified.

History

In 1988, researchers at Uppsala University Hospital and the Karolinska Institute in Stockholm mapped the MEN1 gene to the long arm of chromosome 11. The gene was finally cloned in 1997.

Genomics

The gene is located on long arm of chromosome 11 (11q13) between base pairs 64,570,985 and 64,578,765. It has 10 exons and encodes a 610-amino acid protein.
