Fontan's correction has been performed without early death in 24 consecutive patients with tricuspid atresia. Eighteen patients had ventriculoarterial concordance (group I) and six discordance (group II). Late death related to infections occurred in three patients. The follow-up time in group I (16 survivors) ranges from 1 year 10 months to 7 years 5 months (mean 3 years 8 months) and in group ...

The Performance of electric vehicle IGPT Pin fin heat sink can be measured by the temperature field and the fluid pressure and other parameters. In order to improve the cooling effect of Pin fin heat sink, diameter, length and distance of the fin was optimized combination. The relationship between pressure drop of the water inlet, outlet and pin fin parameters was analyzed and calculated. It wa...

Three dimensional (3D) printing technology is rapidly evolving such that printing speed is now a crucial factor in technological developments and future applications. For printing heads based on the inkjet concept, the number of nozzles on the print head is a limiting factor of printing speed. This paper offers a method to practically increase the number of nozzles unlimitedly, and thus to dram...

Nuclear grade axial flow fans are widely used in nuclear power plants for ventilation and heat dissipation have the advantages of high efficiency rates. A fan with OGVs (outlet guide vanes) can recover kinetic energy dynamic impeller outlet winding to increase ventilator pressure, thus improving efficiency; therefore, play an essential role performance fan. Based on accurate numerical simulatio...

Increasing sustainability awareness has created opportunities for the recovery and reuse of salt solutions in industrial processes. Osmotically assisted reverse osmosis (OARO) potential to concentrate these solutions. Until now OARO research focussed on production purified water yielding an unsaturated solution as retentate, whereas a saturated is often needed reuse. featuring recycling part pe...

Observations from basal water-pressure sensors along the length of Bench Glacier, Alaska, USA, show that diurnal fluctuations of water pressure are seasonal and restricted to summer. Most notable about these fluctuations is their disappearance in the late summer and early autumn, long before the seasonal end of diurnal meltwater input. Here we present data documenting the end of diurnal water-p...

The paper proposes a method to characterize the dynamic behavior of a normal production hydraulic brake system through experiments on a hardware-in-the-loop (HIL) test bench for both modeling (Part I) and control (Part II) tasks. The activity is relative to analyze, model and control ABS/ESC digital valves, aiming at obtaining reference tracking and disturbance-rejection performance similar to ...

We study the flow of an incompressible viscous fluid through a long tube with compliant walls. The flow is governed by a given time-dependent pressure drop between the inlet and the outlet boundary. The pressure drop is assumed to be small, thereby introducing creeping flow in the tube. Stokes equations for incompressible viscous fluid are used to model the flow, and the equations of a curved, ...

OBJECTIVE To describe 11 patients with narrowing of the left ventricular outflow tract caused by angular posterior deviation of both the outlet septum and the upper part of trabecular septum, which was diagnosed by cross sectional echocardiography in all and confirmed by angiocardiography in seven. RESULTS Four patients had a subaortic systolic pressure gradient ranging from 23 to 70 mm Hg by...

UNLABELLED Venoarterial extracorporeal membrane oxygenation (VA-ECMO) can be lifesaving in patients with cardiopulmonary collapse. However, observation studies have implied that oxygenated blood does not pass in a retrograde fashion from the VA-ECMO circuit to the aortic root and arch when the femoral artery (FA) is used. This study aims at accurately measuring the oxygen saturation in various ...
