Tellurium hexafluoride
Tellurium hexafluoride is a chemical compound of tellurium and fluorine with the chemical formula TeF6. It is a colorless, highly toxic gas with an extremely unpleasant smell.
Preparation
Tellurium hexafluoride is most commonly prepared by passing fluorine gas over tellurium at 150 °C. Below this temperature a mixture of lower fluorides form, including tellurium tetrafluoride and ditellurium decafluoride. It can also be prepared by passing fluorine gas over TeO3 or indirectly by reacting TeO2 with SeF4 to produce TeF4 and then heating TeF4 in excess of 200 °C to make TeF6 and Te.
Properties
Tellurium hexafluoride is a highly symmetric octahedral molecule. Its physical properties resemble the sulfur and selenium analogs. It is less volatile, however, due to the increase in molecular weight. At temperatures below −38 °C, tellurium hexafluoride condenses to a volatile white solid.
Reactivity
Unlike the sulfur analog, tellurium hexafluoride is not chemically inert. This can be attributed to the larger atomic radius which can co-ordinate a maximum of eight atoms rather than six for sulfur and selenium which allows for nucleophilic attack. TeF6 is hydrolyzed in water to Te(OH)6 and reacts with Te below 200 °C.
TEAD1
Transcriptional enhancer factor TEF-1 is a protein that in humans is encoded by the TEAD1 gene.
Function
TEAD1 is a member of the mammalian TEAD transcription factor family (initially named the transcriptional enhancer factor (TEF) family), which contain the TEA/ATTS DNA-binding domain.
Interactions
TEAD1 has been shown to interact with MEF2C,Serum response factor and MAX.

Checkmate
Checkmate (Persian: كيش و مات ، kish-o-mat Means King is Defeated) (often shortened to mate) is a game position in chess (and in other board games of the chaturanga a word with persian origin: چترنگ Chatrang family) in which a player's king is in check (threatened with capture) and there is no way to remove the threat. Checkmating the opponent wins the game.
In chess the king is never actually captured – the game ends as soon as the king is checkmated. In master and serious amateur play, most players resign an inevitably lost game before being checkmated, and it is considered bad etiquette to continue playing in a completely hopeless position.
If a player is not in check but has no legal move, then it is stalemate, and the game immediately ends in a draw. A checkmating move is recorded in algebraic notation using the hash symbol (#) – for example, 34.Qh8#.
Examples
A checkmate may occur in as few as two moves with all of the pieces still on the board (as in Fool's mate, in the opening phase of the game), in a middlegame position (as in the 1956 game called the Game of the Century between Donald Byrne and Bobby Fischer), or after many moves with as few as three pieces in an endgame position.
Checkmate (TV series)
Checkmate is an American detective television series starring Anthony George, Sebastian Cabot, and Doug McClure. The show aired on CBS Television from 1960 to 1962 for a total of 70 episodes and was produced by Jack Benny's production company, "JaMco Productions" in co-operation with Revue Studios. Guest stars included Charles Laughton, Peter Lorre, Lee Marvin, Mickey Rooney and many other prominent performers.
Synopsis
The series chronicled the adventures of a private detective agency set in San Francisco. Created by Eric Ambler, the program involves the cases of the detective agency called Checkmate, Inc. Don Corey and Jed Sills run the agency, which specializes in preventing crimes before they happen, from Corey's stylish apartment, supposedly at 3330 Union St. Sebastian Cabot portrays a Ph.D. college professor whom they employ as an adviser. Dr. Hyatt's dachshund Bismarck also appears occasionally. Ken Lynch is frequently seen as police dept. contact Lt. Thomas Brand.
