The most common mechanism of absorption for drugs is passive diffusion. This process can be explained through the Fick law of diffusion, in which the drug molecule moves according to the concentration gradient from a higher drug concentration to a lower concentration until equilibrium is reached. Passive diffusion can occur in an aqueous or lipid environment. 2, record 1, English, - passive%20diffusion

La diffusion passive est le mécanisme qui assure le passage transplacentaire de la plupart des médicaments. La membrane placentaire est lipoprotéique et se comporte comme une membrane semi-perméable. La vitesse à laquelle les molécules sont transférées par diffusion passive répond à la loi de Fick. 2, record 1, French, - diffusion%20passive

Passive or long-term diffusion involves mainly fine particles separated from the jet during descent due to turbulence at the interface of the jet and the water column. This fraction, composed of fine particles entrained by currents, is a problem when dealing with contaminated sediment, because contaminants are bound mainly to fine particles. 2, record 2, English, - passive%20diffusion

La diffusion passive ou à long terme, implique surtout des particules fines qui, lors de la descente, se séparent du jet sous l'action de la turbulence à l'interface de celui-ci avec la colonne d'eau. Cette fraction, constituée de particules fines entraînées sous l'action des courants, est problématique lorsqu'il s'agit du rejet en eaux libres de sédiments contaminés, car les contaminants sont surtout liés aux particules fines. 2, record 2, French, - diffusion%20passive
