-Glutamyltransferase: value of its measurement in paediatrics

-Glutamyltransferase (GGT) is a microsomal enzyme that is widely distributed in human tissues involved in secretory and absorptive processes, particularly the bile canaliculi. Serum GGT is elevated in liver diseases affecting the biliary system, such as extrahepatic biliary atresia, sclerosing cholangitis and progressive familial intrahepatic cholestasis (PFIC) type 3. Conversely, two other sub...

Measurement of the Permeability of Biological Membranes

The transport equation describing the flow of solute across a membrane has been modified on the basis of theoretical studies calculating the drag of a sphere moving in a viscous liquid undergoing Poiseuille flow inside a cylinder. It is shown that different frictional resistance terms should be introduced to calculate the contributions of diffusion and convection. New sieving equations are deri...

Relative Permeability Measurement in Rock Fractures

The petroleum industry always requires precise measurement of relative permeability. When it comes to the fractures, the measurement becomes extremely difficult since the saturation in the fractures is hard to calculate. In this study, we are aiming to provide a machine learning approach to distinguish voxel-based water and gas in rock fractures based on Computed Tomography. This research is di...
