The impact of transitions between two-fluid and three-fluid phases on fluid configuration and fluid-fluid interfacial area in porous media

Stabilizing fluid–fluid displacements in porous media through wettability alteration

We study experimentally how wettability impacts fluid–fluid displacement patterns in granular media. We inject a low-viscosity fluid (air) into a thin bed of glass beads initially saturated with a more-viscous fluid (a water/glycerol mixture). Chemical treatment of glass surfaces allows us to control the wetting properties of the medium and modify the contact angle θ from 5 deg (drainage) to 12...

the influence of corpus luteum on follicular fluid composition from different size follicles and their relationship to serum concentrations in sanjabi ewes

the aim of the present study was to determine the in?uence of presence or absence of corpus luteum (cl) on hormonal and metabolites composition of follicular ?uid (ff) harvested from different sized follicles and its relationship with blood serum concentrations in sanjabi ewes. ovaries and blood samples were collected from 60 clinically healthy adult ewes (sanjabi breed) 1–3 years of age in dio...

Experimental Investigation of the Permeability and Inertial Effect on Fluid Flow through Homogeneous Porous Media

The value of the permeability in fluid flow through porous media is important for process investigation. In low Reynolds number, the classic Darcy’s law is suitable for simulation of fluid flow. In this paper, an experimental study for evaluation of preformed fiber permeability has been done. Also, the deviations from the classical Darcy law by experimental and numerical simulation of the N...

The Comparison of Maternal Endometritis in Meconium – Stained Amniotic Fluid and Clear Amniotic Fluid

Introduction: Metritis is one of the causes of maternal morbidity and there are many risk factors for it. Because of the importance of possible association of meconium-stained amniotic fluid and maternal metritis the present study was done to determine whether meconium stained amniotic fluid (MSAF) is associated with puerperal infection. Methods: In this case-control study 150 women with MSAF a...
