Journal bearing misalignment arise generally from the shaft deformation under load, deflection of the shaft, manufacturing and assembly errors, improper installation, and asymmetric loading. During operations, misalignment has a considerable effect on the static and dynamic performances. It could cause wear, vibration and even system failure. In this article, a literature review of misalignment...

scesses formed, pieces of bone came away, and a purulent discharge has lasted since then. He was admitted into the hospital on 28th April, for syphilitic necrosis of the head and upper part of the shaft of the left tibia. There were several cloaca, exuding fetid pus in large quantity, round the head of the bone and, in front below the tubercle, there was a large circular gap surrounded by scler...

Technical difficulties during colorectal surgery increase the complication rates. We introduce a modified single stapler technique for patients in whom technical problems are encountered while performing double stapler technique. Before pelvic dissection, descending colon is divided at minimum 10 cm proximal to the tumoral segment. Tumor specific mesorectal excision is performed and two purse s...

A passive jet flow control method for suppressing unsteady vortex shedding from a circular cylinder via a numerical simulation is presented in this paper. The circular cylinder is wrapped in a hollow pipe. There are a set of the suction/jet holes on the windward side and leeward side of the outer surface of the pipe. The oncoming flow enters into the hollow pipe through the inlet holes and then...

Functionally graded materials (FGMs) enable one to tailor the spatial variation of material properties so as to fully use the material everywhere. For example, in a hollow circular cylinder one can vary, in the radial direction, the material moduli to make the hoop stress constant. Whereas the problem for a hollow cylinder with the inner and the outer surfaces circular has been studied, that of...

We find closed-form solutions for axisymmetric plane strain radial deformations of a functionally graded circular hollow cylinder and radial expansion/contraction of a hollow sphere loaded on inner and outer surfaces by uniform hydrostatic pressures. The cylinder and the sphere are presumed to be made of isotropic and incompressible linear elasticmaterials with the shearmodulus a general functi...

Axisymmetric vibration of an infinite Pyrocomposite circular hollow cylinder made of inner and outer pyroelectric layer of 6mm-class bonded together by a Linear Elastic Material with Voids (LEMV) layer is studied. The exact frequency equation is obtained for the traction free surfaces with continuity condition at the interfaces. Numerical results in the form of data and dispersion curves for th...
