background:   hallux valgus deformity is a common chronic problem in middle age and elderly. different surgical procedures have been introduced so far with their proposed indications for each. this study aimed to compare three   current procedures namely chevron osteotomy, scarf osteotomy and mcbride technique.     methods:   in this study, 44 patients were included from 2010 to 2013. all patie...

Fluidic chevrons use injected air near the trailing edge of a nozzle to emulate mixing and jet noise reduction characteristics of mechanical chevrons. While previous investigations of “first generation” fluidic chevron nozzles showed only marginal improvements in effective perceived noise levels when compared to nozzles without injection, significant improvements in noise reduction characterist...

ID No. : FC-168 ABSTRACT Fiber-reinforced self-healing ceramic (shFRC) [1] is considered to be most attractive candidate of next generation structural materials using at high temperature, e.g. turbine blade, exhaust component of car engine etc. The shFRCs consist of three components, which are oxide fiber bundle, oxide matrix and self-healing agent interlayer. As the self-healing is generated a...

Abstract Full control of magnetic properties in exchange coupled systems requires a good understanding 3D configuration with lateral and in-depth resolution. Here we show results from soft X-ray tomographic reconstruction which allow determining, solely the experimental data, detailed description vector ferrimagnetic Gd 12 Co 88 /Nd 17 83 /Gd 24 76 trilayer engineered competing anisotropy, magn...
