Pressure measurement because atmospheric pressure is always changing and the reference in this case is fixed at 1 bar. To produce an absolute pressure sensor, the manufacturer seals a high vacuum behind the sensing diaphragm. If the process-pressure connection of an absolute-pressure transmitter is open to the air, it will read the actual barometric pressure. The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N·m or kg·m·s). This special name for the unit was added in 1971; before that, pressure in SI was expressed in units such as N·m. When indicated, the zero reference is
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
