In-situ synchrotron x-ray experiments have been used to follow the evolution of the diffraction peaks for crystalline dendrites embedded in a bulk metallic glass matrix subjected to a compressive loading-unloading cycle. We observe irreversible diffraction-peak splitting even though the load does not go beyond half of the bulk yield strength. The chemical analysis coupled with the transmission ...

The present study theoretically investigates the radiative properties of a two-dimensional (2-D) multilayer structure that has a dielectric spacer between a metallic substrate and square cross-sectional metallic gratings. Differently from the one-dimensional metallic strips coated on a dielectric spacer atop an opaque metallic film [Opt. Express 16, 11328 (2008)], the 2-D metallic gratings can ...

The distraction osteogenesis (DO) technique has been used worldwide to treat many orthopaedic conditions. Although successful, absent or delayed callus formation in the distraction gap can lead to significant morbidities. An alternate cycle of distraction-compression (accordion maneuver) is one approach to accelerate bone regeneration. The primary aim of our study is to report our experience wi...

Some applications in microelectronics call for freestanding polyimide films with fine metallic wiring patterns that are thinner than commercially available copper-clad polyimide sheets, which are typically greater than 25 pm in thickness. This work describes a laserassisted technique to fabricate freestanding multilayer thin-film wiring with polyimide dielectric insulating layers that are less ...

The coronary "accordion" effect is a rare pseudo-complication of percutaneous coronary intervention (PCI). It is usually observed due to straightening and shortening of tortuous vessels with stiff guidewires during PCI. In this case report, we present an interesting case of the coronary accordion effect observed in a 52-year-old woman undergoing PCI.

In the present paper work an attempt has been made to study dynamic behaviour of elevated water tank staging by using x-plate metallic damper subjected blast induced ground vibrations. The main objective this is reduce damage providing structural response control devices. modelled in SAP 2000 and non-linear time history analysis carried out know performance under four different intensity motion...
