introduction fungal prosthetic valve endocarditis (pve) is rare but serious complication of valve replacement surgery. candida species, particularly candida albicans is the most common isolated pathogen in fungal pve (1–6%of cases). case presentation we describe a 35-year-old woman who underwent mechanical mitral valve replacement about 3 years ago. she was admitted with neurological symptoms a...

As a core component in the gas transmission process, internal wall surface of pressure regulator is prone to failure due long-term exposure high-pressure environment, resulting poor reliability regulator. Thus, thermo-hydro-mechanical coupling model for FL established this paper, and results are verified by engineering data. The effect valve opening on parameters (temperature, deformation, stre...

introduction cerebral haemorrhage could complicate post operative course after cardiac surgery, especially after multiple mechanical valves replacement needing for anticoagulation. the interruption of vitamin k antagonists in this cases, to avoid the enhancement of the cerebral haemorrhage, can be performed with reasonable safety. case presentation we report the case of a patient who underwent ...

A complete thermo-hydro-mechanical model is presented to tackle the complex coupling problems encountered in clay barriers. A detailed formulation coupling the heat, moisture (liquid water and water vapour) and, air transfer in a deformable unsaturated soil is given. The formulation of the AlonsoGens’s mechanical model for unsaturated soil is also incorporated. The sensitivity to some parameter...

Abstract The aim of the present work is synthesis and optimal tunning a PID controller designed to control displacement volume an axial-piston pump intended for hydraulic systems with open circulation. controlled in real-time through system developed by authors based on electro-hydraulic proportional valve (replacing conventional hydro-mechanical controller) industrial controller. experimental ...

OBJECTIVE Neurocognitive deficit is an important complication in patients undergoing open heart surgery. The aim of this prospective, contemporary study was to objectively measure neurocognitive brain function following mechanical mitral valve replacement and mitral valve repair. METHODS Forty consecutive, unselected patients (mechanical valve replacement n=20, mean age 65+/-14; valve repair ...

BACKGROUND Mechanical valves and bioprostheses are widely used for aortic valve replacement. Though previous randomised studies indicate that there is no important difference in outcome after implantation with either type of valve, knowledge of outcomes after aortic valve replacement is incomplete. OBJECTIVE To predict age and sex specific outcomes of patients after aortic valve replacement w...

Power Generation from Renewable energy sources like wind, solar, geothermal, biomass, and hydro is predominant now days and among the renewable energy sources, small hydro and wind energy have the ability to complement each other. For Power generation by small or micro hydro as well as wind systems, the use of squirrel-cage induction generators (SCIGs) is mostly adopted. As regards in recent ye...

OBJECTIVE Surgery remains the primary form of treatment for infective endocarditis (IE). However, it is not clear what type of prosthetic valve provides a better prognosis. We conducted a meta-analysis to compare the prognosis of infective endocarditis treated with biological valves to cases treated with mechanical valves. METHODS Pubmed, Embase and Cochrane databases were searched from Janua...
