The Variant Call Format or VCF is a standard text file format used in bioinformatics for storing gene sequence variations. The format was developed in 2010 for the 1000 Genomes Project and has since been used by other large-scale genotyping and DNA sequencing projects. [ 1][ 2] VCF is a common output format for variant calling programs due to ...
British Standard Whitworth. British Standard Whitworth ( BSW) is an imperial-unit -based screw thread standard, devised and specified by Joseph Whitworth in 1841 and later adopted as a British Standard.

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 ]
1. Turn immediately to Part One and start answering the ten Best Year Yet questions.
