We study how grain shapes impact multiphase flow in porous media the quasi-static regime using an extended pore-network model. The algorithm allows explicit determination of different types pore-scale instabilities and tracks interface motion during fluid-fluid displacement process. It also includes volume capacitance model, such that both evolution capillary pressure signal sizes Haines jumps ...

Classically described; pleural effusion is the accumulation of fluid in the pleural gap that may be caused by any reason [4]. If there is an evidence of invasion by the tumor or any malignant cells detected in this fluid, it is described as malignant pleural effusion. Although there has been no epidemiologic study with respect to pleural effusion yet, it is a common clinic problem which is esti...

Clinical chorioamnionitis at term (TCC) is the most common obstetrical infliction diagnosed in labor and delivery units worldwide and is associated with a substantial increase in maternal and neonatal morbidity and mortality. This obstetrical complication is a heterogeneous condition, as only half of patients have detectable microorganisms in the amniotic cavity. Because bioactive lipids play a...

From the invasive Citrobacter freundii strain 3009, an invasion determinant was cloned, sequenced, and expressed. Sequence analysis of the determinant showed high homology with the fim determinant from Salmonella enterica serovar Typhimurium. The genes of the invasion determinant directed invasion of recombinant Escherichia coli K-12 strains into human epithelial cell lines of the bladder and g...

We present experiments and theory describing the transition from viscosity-stabilized flow to gravitationally unstable fingering for two-phase in a cubic box, filled with synthetic porous medium. Observation is made possible by use of our newly developed table-top 3D scanner based on optical index matching laser-induced fluorescence, which described detail. In experiment, more dense, viscous fl...

the ability of subminimum inhibitory concentrations (sub-mics) of antibiotics to affect the virulence factors of bacteria may be an important criterion in selecting an antibiotic for therapy. proteus mirabilis is one of the most frequently seen pathogens in urinary tract infections. the aim of this study was to analyze the effects of some antibiotics on two important virulence factors of p. mir...

conclusions the proliferation and invasion of human bladder cancer cells can be inhibited by rnai-targeting skp2. as a result, skp2 may be a potential target for gene therapy in cases of human bladder cancer. materials and methods the expression of the skp2 gene was knocked down by rna interference (rnai) in t24 cells. the transcription level of skp2 was detected by reverse transcription-quanti...

We present an interface tracking algorithm that incorporates essential pore-scale invasion mechanisms for simulating multiphase flow in porous media capillary dominated regime. The allows the capture of actual shape medium with complex geometrical features, including both convex and concave particles or irregular channels. It also sharp edge pinning effect such menisci at corners can be natural...
