This paper discuss about the critical review on design of carbon nanotube based MEMS piezoresistive pressure sensors, use of different types of carbon nanotubes such as multi-walled carbon nanotubes (MWCNTs), single-walled carbon nanotubes (SWNTs) and vertically aligned carbon nanotubes (VANTs), sensing mechanism, applications, etc. The structural deformation of the piezoresistive nano structur...

Plastic injection molding is discontinuous and a complicated process involving the interaction of several variables for control the quality of the molded parts. The goal of this research was to investigate the optimal parameter selection, the significant parameters, and the effect of the injection-molding parameters during the post-filling stage (packing pressure, packing time, mold temperature...

The arteries, veins, capillaries and lymphatic vessels that comprise the vertebrate vascular system function to transport blood and lymphatic fluid to and from the tissues. It is therefore unsurprising that development, maintenance and physiology of these structures are strongly influenced by mechanical forces such as pressure and fluid shear stress associated with fluid flow (Hahn and Schwartz...

The interaction force between functionalized single-walled carbon nanotubes (SWNTs) plays an important role in the fabrication of self-assembled and highly ordered SWNT arrays for a wide range of potential applications. Here, we measured interaction force between SWNTs encapsulated with polymerized surfactant monolayer (p-SWNTs). The balance between the repulsion between p-SWNTs and the osmotic...

Pulmonary microvessels (<70 microm) lack a complete muscular media. We tested the hypothesis that these thin-walled vessels do not participate in the hypoxic pressor response. Isolated canine lobes were pump perfused at precisely known microvascular pressures. A videomicroscope, coupled to a computerized image-enhancement system, permitted accurate diameter measurements of subpleural arterioles...

In this work, the stress distribution along cylindrical composite pressure vessels with different dome geometries is investigated. The contours are generated through an integral method based on shell stresses. Here, influence of each contour at interface dome-cylinder evaluated. At first, formulation for curve generation presented and solved contours. An analytical approach calculation secondar...

Angioleiomyoma (vascular myoma) is a rare type of leiomyoma originating from smooth muscle cells and containing thick-walled vessels. There are only a few cases of retroperitoneal angioleiomyoma reported in the literature. Herein, we present the ultrasonography, magnetic resonance imaging and histopathological findings of an asymptomatic patient with a pelvic retroperitoneal angioleiomyoma whic...
