Inhaled Beta Agonist Bronchodilator Does Not Affect Trans-diaphragmatic Pressure Gradient but Decreases Lower Esophageal Sphincter Retention Pressure in Patients with Chronic Obstructive Pulmonary Disease (COPD) and Gastroesophageal Reflux Disease (GERD)
(Springer, 2016)
Background Chronic obstructive pulmonary disease (COPD) patients have a high incidence of gastroesophageal reflux disease (GERD) whose pathophysiology seems to be linked to an increased trans-diaphragmatic pressure gradient ...
Simulador de escoamento multifásico em poços de petróleo (SEMPP)
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia do PetróleoPesquisa e Desenvolvimento em Ciência e Engenharia de Petróleo, 2013-02-07)
The multiphase flow occurrence in the oil and gas industry is common throughout fluid
path, production, transportation and refining. The multiphase flow is defined as flow
simultaneously composed of two or more phases ...
Analytical solution for transient one-dimensional couette flow considering constant and time-dependent pressure gradients
(2011)
This paperaims to determine the velocity profile, in transient state, for a parallel incompressible flow known as Couette flow. The Navier-Stokes equations were applied upon this flow. Analytical solutions, based in Fourier ...
Estudo computacional da difusão de água em nanotubos de carbono induzida por gradiente de pressão
(Universidade Federal de Santa MariaBRFísicaUFSMPrograma de Pós-Graduação em Física, 2013-02-08)
In this work we present a computational study of the properties of water transport
across membranes formed of carbon nanotubes (CNT) armchair with different diameters,
when subjected to pressure gradients 80-400 MPa. This ...
Vertical well pressure and pressure derivative analysis for bingham fluids in homogeneous reservoirs
(Universidad Nacional de Colombia Sede Medellín, 2011)
This paper presents a technique for interpreting the behavior of pressure and pressure derivative for a Bingham-type fluid in a homogeneous reservoir drained by a vertical well using the TDS technique, by observing the ...
