Exempel på surfactant

• Early versus delayed selective surfactant treatment for neonatal respiratory distress syndrome.

• This property results from neglecting the surfactant diffusion.

• The pediatric cardiologist was unaware which babies had received surfactant.

• Here, the surfactant is swept to the back of an advancing bubble and accumulates near the rear.

• In this paper we derive a simple mathematical model describing the flow of micellar surfactant solution beneath a gas-liquid interface.

• Consequently, when surfactant solution flows beneath a free surface, the fluid dynamics and surface chemistry are, in general, intimately coupled.

• These variables include surfactant, common radiological investigations, blood product transfusions, surgery, and echocardiography.

• A candidate might be the variation of agar surface tension along the envelope due to some surfactant secreted by the bacteria.

• We found only a trace of surfactant in the lumen of alveoli.

• We finally note here that if surfactants are present, the interface will be tangentially immobile independently of the viscosity ratio.

• All these models neglect fluid motion and thus surfactant transport by convection.

• Increased expression of pulmonary surfactant proteins in oxygen-exposed rats.

• Before we carry out a perturbation analysis of the surfactant equations, we shall examine the momentum equation in the static cap region.

• There are several mechanisms which determine the distribution of interfacial surfactants.

• It is becoming more apparent that alveolar epithelial cells have functions other than gas exchange and pulmonary surfactant production.
