Methods Experiment A. We analyzed heat dispersion of an ECMO circuit (Maquet Rotaflow PLS System) at 36 combinations of blood flow (BF 1-3-5 L/min), gas flow (GF 0-510 L/min) and set temperature (T set 36-37-38-39 °C). In any condition, heat dispersion was considered equal to the power (Watts) generated by the heat exchanger at the steady state, defined as stable temperature throughout the circ...

Spin-charge separation in the one dimensional electron gas should give rise to two peaks in the single hole spectral function. However, unambiguous detection of these two peaks has proven difficult, since the combined effects of interactions, thermal broadening, and finite experimental resolution can suppress the spin peak. Nevertheless, a telltale kink in the dispersion remains, and the system...

A hot stage attached to the phase shifting digital holographic interferometry (DHI) is used to study the effects of temperature on the optical properties of basalt fibres. The phase shifting Mach-Zehnder interferometer is used to obtain five phase-shifted holograms, in which the phase difference between two successive holograms is π/2. These holograms are numerically reconstructed using the con...

The temperature dependence of the Casimir force between a real metallic plate and a metallic sphere is analyzed on the basis of optical data concerning the dispersion relation of metals such as gold and copper. Realistic permittivities imply, together with basic thermodynamic considerations, that the transverse electric zero mode does not contribute. This results in observable differences from ...

Light weight materials coupled to the need for cost-effective processing have combined to create a significant opportunity for aluminium powder metallurgy as its increasing interest. Aluminium alloy (AA 2219) metal matrix composite reinforced with multi walled carbon nanotube (MWCNT) produced by powder metallurgy (P/M) technique was analysed and CNTs dispersion were traced. The micro hardness a...

At z=0.809, RXJ 1716.6+6708 is the second most distant X-ray selected cluster so far published and the only one with a large number of spectroscopically determined cluster member velocities. The optical morphology of RXJ 1716.6+6708 resembles an inverted S-shape filament with the X-rays coming from the midpoint of the filament. The ROSAT HRI contours have an elongated shape that roughly coincid...

Palladium supported on high-surface-area ceria effectively catalyzes the hydrogenation of phenol to cyclohexanone at atmospheric pressure and room temperature. Activation of H2 at Pd sites and phenol at surface ceria sites was investigated by probing the redox properties of the catalyst and studying the mechanism of phenol adsorption. Temperature-programmed reduction and pulsed chemisorption we...

composite electrodeposition is a low-cost and low-temperature method, which is used to make metal matrix composite coatings. in this study the surfactant of anionic(sds) and cationic (ctab) is used as additive in composite coating of ni/tin. the results showed that the anionic surfactant caused more particles in the composite coatings. increasing sds concentration to the optimal value leads to ...

a mathematical model is described and applied for adsorption process of ethyl acetate from supercritical co2 stream on activated carbon particles. this model has the ability of illustrating variation of effluent concentration towards different parameters such as flow rate, temperature and pressure. in this research, a vast area of operational conditions is experienced. mass transfer resistance ...

This study presents methods for treating a kind of nanoclay and investigates the effects of methylaluminoxane (MAO) exposure time and or dodecylamine (DDA) reflux time on in-situ polymerization of ethylene in the presence of nanoclay and examines the morphology and properties of the prepared polyethylene/clay nanocomposites. The results revealed that by increasing MAO exposure time productivity...
