Nano fluids are having wide area of applications in heat transfer equipments. In the present work graphene nanoparticles, Dispersed in De-ionized water (DI), Ethylene Glycol (EG) based nano fluids were developed. Thermal conductivity and convective heat transfer properties of these nanofluids were systematically investigated. In the present investigation thermal convection of glycol based nanof...

BACKGROUND Fluid resuscitation in massive bleeding may cause coagulation disorders by dilution of platelets and clotting factors or by the definite influence on theirfunction. The aim of this study was to investigate the effects of balanced crystalloid and colloid solutions on platelets (PLT) in vitro using complex assessment of coagulation. METHODS The study group was comprised of 32 America...

in this paper, the transient inertial viscoelastic flow around a circular cylinder is investigated numerically. a second order finite-volume method is used to increase the numerical accuracy. here, the giesekus model is used as the constitutive equation. this nonlinear model has prominent ability in describing normal stress differences and viscosity in power-law regions. the impacts of the elas...

Background: During resuscitation trauma patients receive various intravenous fluids, which can exacerbate coagulopathy and haemorrhage further. This led to the introduction of the damage control resuscitation, which advocates minimal intravenous fluids use. However, some fluid may be required in uncontrolled haemorrhage or when blood products are not immediately available. Furthermore, question...

Mount Rainier is one of the most seismically active volcanoes in the Cascade Range, with an average of one to two high-frequency volcano-tectonic (or VT) earthquakes occurring directly beneath the summit in a given month. Despite this level of seismicity, little is known about its cause. The VT earthquakes occur at a steady rate in several clusters below the inferred base of the Quaternary volc...

INTRODUCTION Use of hydroxyethyl starch (HES) in septic patients is reported to increase the mortality and incidence of renal replacement therapy (RRT). However, whether or not use of HES would induce the same result in non-septic patients in the intensive care unit (ICU) remains unclear. The objective of this meta-analysis was to evaluate 6% HES versus other fluids for non-septic ICU patients....

children, similar to adults, are required to fast before general anesthesia in order to reduce  the volume and acidity of stomach contents. it is thought that npo regulations reduce the risk of regurgitation and aspiration of gastric contents during surgery. recent developments have encouraged a shift from the standard 'nil by mouth from midnight' fasting policy to more relaxed regime...

Nanofluids are solutions of a small fraction of suspended nanoparticles in a bulk fluid. Nanofluids have shown great promise as heat transfer fluids over typically used bulk fluids and fluids with micron sized particles. The nanoparticles do not settle in the fluid and do not cause clogging or damage to surfaces as with micron sized particles. In the current work we compare the performance of d...

A two-phase approach has been proposed to study the supercritical flow with heat transfer deterioration (HTD) phenomena so that an analogy can be derived between subcritical boiling and transfer. The volume of fluid multiphase model used analyze flow, simulation result reasonably predicts wall temperature peaks. Moreover, velocity turbulent kinetic energy profiles at different axial locations e...
