Bromochlorodifluoromethane (BCF), also referred to by the code numbers Halon 1211 and Freon 12B1, is a haloalkane with the chemical formula C F 2 Cl Br. It is used for fire suppression, especially for expensive equipment or items that could be damaged by the residue from other types of extinguishers. [ 1 ]
A standard 52-card French-suited deck comprises 13 ranks in each of the four suits: clubs (♣), diamonds (♦), hearts (♥) and spades (♠).

Diaconis, Graham, and Kantor also call this the technique, when used in magic. [1]
Tris (pentafluorophenyl)borane, sometimes referred to as "BCF", is the chemical compound (C6F5)3B. It is a white, volatile solid. The molecule consists of three pentafluorophenyl groups attached in a "paddle-wheel" manner to a central boron atom; the BC3 core is planar. It has been described as the “ideal Lewis acid ” because of its high ...
Tablet weaving (often card weaving in the United States) is a weaving technique where tablets or cards are used to create the shed through which the weft is passed. As the materials and tools are relatively cheap and easy to obtain, tablet weaving is popular with hobbyist weavers. Most tablet weavers produce narrow work such as belts, straps ...
Fugacity and BCF relate to each other in the following equation: = [6] where Z Fish is equal to the Fugacity capacity of a chemical in the fish, P Fish is equal to the density of the fish (mass/length 3), BCF is the partition coefficient between the fish and the water (length 3 /mass) and H is equal to the Henry's law constant (Length 2 /Time 2) [6]
The standard 52-card deck is often augmented with jokers or even with the blank card found in many packaged decks. In France, the 32-card piquet stripped deck is most typically used in cartomantic readings, although the 52 card deck can also be used. (A piquet deck can be a 52-card deck with all of the 2s through the 6s removed.
Cribbage uses a standard 52-card deck of cards. The jokers are removed; the suits are equal in status. The players cut for first deal, with the player cutting the lowest card (the ace counts as one, and is the lowest card) dealing first. If the cutters tie, the cards are re-shuffled and re-cut. The deal then alternates from hand to hand.
