In this work, through constructing an auxiliary problem totally driven by the fluid velocity (free flow region) along interface, we propose a new analysis strategy to establish priori estimate of weak solutions steady-state dual-porosity-Navier-Stokes model with Beavers-Joseph-Saffman interface condition. As result, both and existence result are independent small data large viscosity restrictio...

A new method is proposed to solve the hydrodynamics performances of a fluid lubricated screw-nut pair using FLUENT. Before simulations, Computational Fluid Dynamics (CFD) model gap flow field built, based on some approximation rules. During dynamic mesh technology employed realize real-time update grids computational domain. For given velocity perturbation, stiffness and damping coefficients sy...

We examined potential mechanisms by which angiotensin subtype-2 (AT2) receptor stimulation induces net fluid absorption and serosal guanosine cyclic 3',5'-monophosphate (cGMP) formation in the rat jejunum. L-arginine (L-ARG) given intravenously or interstitially enhanced net fluid absorption and cGMP formation, which were completely blocked by the nitric oxide (NO) synthase inhibitor, N-nitro-L...

Gravity waves arise in gravitationally stratified compressible flows at low Mach and Froude numbers. These waves can have a negligible influence on the overall dynamics of the fluid but, for numerical methods where the acoustic waves are treated implicitly, they impose a significant restriction on the time step. A way to alleviate this restriction is to filter out the modes corresponding to the...

Restriction fragment length polymorphism (RFLP) analysis of the PCR-amplified proximal region of the gene encoding cytadherence accessory protein P110 (MG192) revealed DNA sequence divergences among 54 Mycoplasma genitalium clinical strains isolated from the genitourinary tracts of women attending a sexually transmitted disease-related health clinic, plus one from the respiratory tract and one ...

We present a smoothed particle hydrodynamic model for incompressible fluids. As opposed to solving a pressure Poisson equation in order to get a divergence-free velocity field, here incompressibility is achieved by requiring as a kinematic constraint that the volume of the fluid particles is constant. We use Lagrangian multipliers to enforce this restriction. These Lagrange multipliers play the...

BACKGROUND Excessive intravenous fluid prescription may play a causal role in postoperative complications following major gastrointestinal resectional surgery. The aim of this study was to investigate whether fluid and salt restriction would decrease postoperative complications compared with a more modern controlled liberal regimen. METHODS In this observer-blinded single-site randomized clin...

Iron restriction is the body’s removal of freely available iron from blood and extracellular fluid, as part of the systemic inflammatory response [1]. This process is mediated by hepcidin, which ‘locks’ iron into somatic cells by down-regulating the iron exporter protein ferroportin [2]. Iron accumulates within macrophages, hepatocytes and gut enterocytes, but cannot enter the circulation [1, 2...
