Whether migration of granulocytes across pulmonary vascular endothelium in the absence of structural evidence of endothelial injury causes increased production of thromboxane or prostacyclin is not known. Using bovine pulmonary artery intimal explants mounted in Boyden chambers and homologous separated granulocytes, concentrations of thromboxane B2 and 6-keto-PGF1 alpha in the upper-well fluid ...

Multi phase fluids are common in energy-related geotechnical problems, including gaswater, gas-oil, ice-water, hydrate-water, and oil-water fluid conditions. The generalization of classical unsaturated soil mechanics concepts to energy geotechnology requires physical understanding of surface tension, contact angle, capillary pressure, solubility and nucleation. Eventually, these pore-level proc...

It also examines historical patterns migration to GCC region with a focus on socioeconomic impact skilled immigration Indian expatriates UAE economy. Furthermore, chapter attempts asses...

The migration of endothelial cells (ECs) plays an important role in vascular remodeling and regeneration. EC migration can be regulated by different mechanisms such as chemotaxis, haptotaxis, and mechanotaxis. This review will focus on fluid shear stress-induced mechanotransduction during EC migration. EC migration and mechanotransduction can be modulated by cytoskeleton, cell surface receptors...

Controlled manipulation of particles from very large volumes of fluid at high throughput is critical for many biomedical, environmental and industrial applications. One promising approach is to use microfluidic technologies that rely on fluid inertia or elasticity to drive lateral migration of particles to stable equilibrium positions in a microchannel. Here, we report on a hydrodynamic approac...

Fluoride-rich fluid is believed to be able activate and migrate Ti other high field-strength elements the greatest extent. The stability of F-rich titanium complexes can ensure their migration in fluid, but inseparable from physical chemical properties such as concentration, temperature pH value—important factors affecting complexes. In this study, influence outer cationic complex on fluorine w...

Gas disaster prevention and control is essential to coal mine safety production, with accurate measurement of gas pressure content being the challenging key aspect. Pressure- gas-maintaining coring devices can characterize cores in situ achieve this measurement. As an important part these devices, hydraulic structure bit plays a decisive role migration, rate, core disturbance bottom-hole cuttin...

Many cells respond to fluid shear stress but in a cell type-specific fashion. Fluid shear stress applied to leukocytes serves to control pseudopod formation, migration, and other functions. Specifically, fresh neutrophils or neutrophilic leukocytes derived from differentiated HL60 cells respond to fluid shear stress by cytoplasmic pseudopod retraction. The membrane elements that sense fluid she...

The evaluation of possible leakage pathways from CO2 storage operations requires attention to the magnitude, concentration and timescales involved. Herein we discuss a problem related to CO2 storage, the migration of CO2 as it is injected. This is accomplished through the application of analytical solutions. In particular, we derive a new analytical insight into the problem of fluid injection i...

Endothelial migration is an important process in the formation of blood vessels and the repair of damaged tissue. To study this process in the laboratory, versatile and reliable migration assays are essential. The purpose of this study was to investigate whether the microfluidic version of the conventional wound-healing assay is a useful research tool for vascular science. Endothelial cells wer...
