Reconstructing weight-bearing surfaces: digital pad transposition.

The paw pads of dogs and cats are specialized skin structures that provide cushioned, durable, weight-bearing surfaces. Otherwise normal limbs may be rendered useless when pad tissue is lost because of trauma or tumor resection. This article reviews previously described reconstructive techniques involving the movement of pad tissue into weight-bearing defects. In addition, a case series of sing...

Flow Visualization Around a Non - Circular Tube

The flow behavior around a cam shaped tube in cross flow has been investigated experimentally using flow visualization and pressure distribution measurement. The range of attack angle and Reynolds number based on an equivalent circular diameter are within 0 ≤ α ≤ 360˚ and 2 x 104 < Reeq < 3.4 x 104, respectively. The pressure drag features are clarified in relation to the flow behavior around t...

A Baseline Theory for the Design of Oil-Lubricated Centrally Pivoted Plane-Pad Thrust Bearings

A baseline theory is developed in this paper for the design of oil-lubricated centrally pivoted plane-pad thrust bearings. By focusing on the hydrodynamics generated by the viscosity-temperature effects of the lubricating oil, a mathematical model is derived with a single dimensionless parameter Wth. The nominal value of Wth is 0.1 for typical pad bearings in current industrial practice. The th...

Magnetic fluid lubrication of porous pivoted slider bearing with slip and squeeze velocity

In this paper the problem on “Magnetic fluid lubrication of porous-pivoted slider bearing with slip velocity by N Ahmad et.al.[7]” has been recapitulated using Jenkin’s model [4] with the additional effect of squeeze velocity of the above plate. It is found that while discussing the above problem, [7] has stated but ignored the term , where +, in their study (Refer equation(2.2)). This paper re...
