BACKGROUND Polymer-coated drug-eluting stents are effective in preventing restenosis but have been associated with delayed healing and incomplete strut coverage. It is unknown whether paclitaxel-eluting stents (PES) with minimal biodegradable abluminal coating enhances strut coverage while preventing neointimal hyperplasia. Using optical coherence tomography (OCT) as a primary imaging modality,...
In this study, the performance of triangular added damping and stiffness (TADAS) dampers combined with curved dampers (Curved-TADAS damper) is evaluated in moment resisting steel frame (MRSF). These dampers are passive and install in the beam-column connection region. Variable parameters of this study involve the width of curved damper (50, 75 and 100 mm), the thickness of TADAS damper (5 and 1...
BACKGROUND The process of restenosis after a stenting procedure is related to local biomechanical environment. Arterial wall stresses caused by the interaction of the stent with the vascular wall and possibly stress induced stent strut fracture are two important parameters. The knowledge of these parameters after stent deployment in a patient derived 3D reconstruction of a diseased coronary art...
BACKGROUND Although bioresorbable scaffolds offer potential advantages compared with metallic drug-eluting stents in the treatment of complex coronary bifurcation lesions, there are concerns that the polymeric scaffold integrity may be compromised. This in vivo study sought to provide insights about the feasibility of performing complex bifurcation stenting with Absorb bioresorbable vascular sc...
Reduction of Unsteady Stator–Rotor Interaction by Trailing Edge Blowing Using MEMS Based Microvalves
i Reduction of Unsteady Stator – Rotor Interaction by Trailing Edge Blowing Using MEMS Based Microvalves by Nikhil M. Rao Dr. W.F. Ng, Chairman Mechanical Engineering (ABSTRACT) This research performs an experimental study of a trailing edge blowing system that can adapt to variations in flow parameters and reduce the unsteady stator-rotor interaction at all engine operating conditions. The fan...
Truss structures composed of members that work exclusively in tension or compression appear several problems science and engineering, e.g., the study resisting mechanisms masonry structures, as well design spider web-inspired web structures. This generalizes previous results on existence cable webs are able to support assigned sets nodal forces under tension. We extend such a problem limit anal...
In 1995, Allen Fisher published a poem entitled ‘Mummers’ Strut’ in an issue of the magazine West Coast Line,[1] accompanied by a statement of poetics. The poem is organised into twentyseven short numbered sections, mostly in couplets, ranging from two to twenty lines in length. The predominant impression is of a fragmented discourse that is hard to read as constructing a consistent speaking vo...
