This idea is supported by the finding of a statistically significant association between intrahepatic expression of CXCL9 and the inflammatory activity of chronic hepatitis C [ 35 ].
WebA Centrifugal compressor is dynamic turbomachinery so increases the pressure of a gas by adding kinetic energizer through an impeller. The well-known French genius, Professor Auguste Rateau, invented the centrifugal compressor in the late 19th century.
