Pascal (unit) dB SPL, or 20 µPa. The airtightness of buildings is measured at 50 Pa. The units of atmospheric pressure commonly used in meteorology were formerly the bar, which was close to the average air pressure on Earth, and the millibar. Since the introduction of SI units, meteorologists generally measure pressures in hectopascals (hPa) unit, equal to 100 pascals or 1 millibar. Exceptions include Canada, which use kilopascals (kPa). In many other fields of science, the SI is preferred, which means Pa with a prefix (in multiples of 1000) is preferred. Many countries also use the millibars. In practically all other
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
