The renal countercurrent exchange mechanism was studied by recording the removal of hydrogen gas from the medulla of dogs. Hydrogen was administered by respiration or by intra-arterial infusion of ...

ABSTRACT: A significant development in the theory of countercurrent extraction will be presented in this article. New expressions of the term in countercurrent extraction process analysis, “Adjacent ...

A novel countercurrent chromatography solvent system, utilizing deep eutectic solvents, offers efficient separation of trans-crocetin and cis-crocetin from Gardenia jasminoides Ellis, enabling ...

The paper bulids a countercurrent multi-effect drying process model which can be expressed as a linear programming(LP) problem with the minimum total energy consumption as target function. Based on ...

In our previous study, a bionic system simulating the cardiovascular system was built to realize a countercurrent multistage microextraction. However, further study on the hydrodynamics and mass ...
