PURPOSE To investigate the osmotic water permeability of lacrimal gland (LG) duct epithelium by means of calculation of filtration permeability and to investigate LG ductal fluid secretion. METHODS Experiments were performed on isolated rabbit LG duct segments maintained in short-term culture. Osmotically determined fluid movement or fluid secretion into the closed intraluminal space of cultu...

The filtration of fluid in 2D porous medium is simulated by the molecular dynamics technique. The high concentration of fluid is created at the initial point in time and the number of fluid particles is investigated in all porous. The concentration of particles pores and parameters of interaction potentials is varied. In all cases the particles concentration decay is well described by exponenti...

in this present study, volume of fluid method in openfoam open source cfd package will be extended to consider phase change phenomena with modified model due to condensation and boiling processes. this model is suitable for the case in which both unsaturated phase and saturated phase are present and for beginning boiling and condensation process needn't initial interface. both phases (liqu...

This study investigates water-sand bursting disasters associated with fractured rock that affect safe mining in the areas of Western China. A broken seepage rheological test device was developed, and tests were conducted on multiple groups samples single-stage axial loading different load levels. When rheology each group stable, mixed fluid injected into at a certain pressure gradient to conduc...

P ulmonary microembolism is associated with the generation of prostaglandin thromboxanes.’ Since pulmonary microembolism also causes lung edema, the generation of these arachidonic acid products may contribute to extravascular fluid accumulation in the lung. Thromboxane A, (TxA,) is a particularly vasoactive substance in the pulmonary circulation since infusion of the cyclic endoperoxide analog...

The aim of the present study was to compare sealing abilities of Resilon/Epiphany (R/E) with those of guttapercha and Kerr Pulp Canal Sealer EWT (GP/PCS). 50 single rooted teeth were randomly divided into 2 groups (n = 22) (R/E; GP/PCS), and 2 control groups (n = 3) (Positive, Negative). Fluid flow rate through the filled roots was measured using a fluid filtration device. The same specimens we...

A mathematical model of renal hemodynamics was used to assess the individual contributions of the tubuloglomerular feedback (TGF) mechanism and the myogenic response to glomerular filtration rate regulation in the rat kidney. The model represents an afferent arteriole segment, glomerular filtration, and a short loop of Henle. The afferent arteriole model exhibits myogenic response, which is act...
