Examplesofsurfactantsurfactant Early versus delayed selectivesurfactanttreatment for neonatal respiratory distress syndrome. From theCambridge English Corpus This property results from neglecting thesurfactantdiffusion. From theCambridge English Corpus The pediatric cardiologist was unaware which babies had receivedsurfactant. From theCambridge English Corpus Here, thesurfactantis swept to the back of an advancing bubble and accumulates near the rear. From theCambridge English Corpus In this paper we derive a simple mathematical model describing the flow of micellarsurfactantsolution beneath a gas-liquid interface. From theCambridge English Corpus Consequently, whensurfactantsolution flows beneath a free surface, the fluid dynamics and surface chemistry are, in general, intimately coupled. From theCambridge English Corpus These variables includesurfactant, common radiological investigations, blood product transfusions, surgery, and echocardiography. From theCambridge English Corpus A candidate might be the variation of agar surface tension along the envelope due to somesurfactantsecreted by the bacteria. From theCambridge English Corpus We found only a trace ofsurfactantin the lumen of alveoli. From theCambridge English Corpus We finally note here that if surfactants are present, the interface will be tangentially immobile independently of the viscosity ratio. From theCambridge English Corpus All these models neglect fluid motion and thussurfactanttransport by convection. From theCambridge English Corpus Increased expression of pulmonarysurfactantproteins in oxygen-exposed rats. From theCambridge English Corpus Before we carry out a perturbation analysis of thesurfactantequations, we shall examine the momentum equation in the static cap region. From theCambridge English Corpus There are several mechanisms which determine the distribution of interfacial surfactants. From theCambridge English Corpus It is becoming more apparent that alveolar epithelial cells have functions other than gas exchange and pulmonarysurfactantproduction.
