Bar (unit) mb (rather than the proper mbar) to denote the millibar. Between 1793 and 1795, the word bar was used for a unit of weight in an early version of the metric system. Atmospheric air pressure is often given in millibars, where standard atmospheric pressure at sea level is defined as 1013.25 mbar, 101.325 kPa, 1.01325 bar, which is about . Despite the millibar not being an SI unit, meteorologists and weather reporters worldwide have long measured air pressure in millibars as the values are convenient. After the advent of SI units, some meteorologists began using hectopascals (symbol hPa) which are
Centre for Genomic Regulation to provide researchers with cutting edge technologies for stem cell biology, stem cell differentiation, organoid formation, and induced pluripotent stem cells. This unit collaborates with the Biomolecular Screening & Protein Technologies Unit for genome editing technology services. Centre for Genomic Regulation The Centre for Genomic Regulation (CRG, "Centre de Regulació Genòmica" in Catalan) is a biomedical and genomics research centre based on Barcelona. Most of its facilities and laboratories are located in the Barcelona Biomedical Research Park, in front of Somorrostro beach. Since July 2015 CNAG (the National Centre for Genomic Analysis), located in the Parc Científic de Barcelona (close
