Visualization and characterization of near-wake flow fields of a flap**-wing micro air vehicle using PIV
Two-dimensional velocity fields are measured using particle image velocimetry (PIV) at four planes in the near-wake region of a pair of the side wings of a flap**-wing micro air vehicle (MAV) designed at Wri...

A Local Resolution Refinement Algorithm Using Gauss–Lobatto Quadrature
The polynomial local resolution refinement has been successfully applied to the counter-flow hydrogen combustion simulation. The solution continuity across the staggered grid interface is reinforced by an effi...

Numerical analysis of metal transfer in gas metal arc welding under modified pulsed current conditions
A method has been proposed to pulsate current in gas metal arc welding (GMAW) to achieve a specific type of desirable and repeatable metal transfer mode, i.e., one drop per pulse (ODPP) mode. This method uses a p...

Physics and Computations of Flows with Adverse Pressure Gradients
For flows with small to mild pressure gradients, turbulence models that satisfy the law of the wall generally result in better agreement with experiments. When the pressure gradients are large, most simple two...

Wikstroemia indica promotes development of nasopharyngeal carcinoma in rats initiated by dinitrosopiperazine
Nasopharyngeal carcinoma was induced in an initiation/promotion model in rats by s.c. injection of dinitrosopiperazine in the nasopharyngeal cavity. This was followed by repeated 10-cal administration of an ex...
