Performance of a Tube-bundle Heat Exchanger in a Rectangular-section Right-angle Bend Duct [PDF]
Three-dimensional numerical simulations are conducted to elucidate the fundamental differences in hydrodynamics and heat transfer performance between heat exchangers arranged in confined rectangular-section right-angle bend ducts and those in straight ...

Power Valve: for low power operation and low stand-by power
The concept of Power Valve is presented. It consists of power switch transistors and control circuits, which give variable impedance to the power supply. The circuit controls the internal power supply voltage of logic circuits and reduces the voltage swing of signals. An experiment using a 130-nm test chip showed a 36.0% operating power reduction for a

Experimental and Numerical Study on the Elimination of Severe Slugging by Riser Outlet Choking
Severe slugging is an unstable multiphase flow pattern occurs in a pipeline riser with low gas and liquid flowrates. It is highly undesired in practical operation because of the pressure and mass flow oscillations induced.

Parent‐to‐Child Information Disclosure in Pediatric Oncology
ABSTRACT Background Despite professional consensus regarding the importance of open communication with pediatric cancer patients about their disease, actual practice patterns of disclosure are understudied. Extant literature suggests a significant proportion of children are not told about their diagnosis/prognosis, which is purported to negatively ...
