A boundary value problem of orthotropic piezoelectric solid circular cylinder which is in the state antiplane shear deformation studied. The whole surface loaded by an equilibrium axial traction. This paper gives analytical solution considered deformation.

Arthroscopic shoulder surgery can be performed in both the beach chair and lateral decubitus positions. The lateral decubitus position allows for excellent exposure to all aspects of the glenohumeral joint and is therefore frequently employed in procedures such as stabilization, in which extensive visualization of the inferior and posterior aspects of the joint is required. Improved visualizati...

Abstract Coiled tubing (CT) is prone to buckling and locking due axial friction when extending in large displacement directional wells horizontal wells. The traction robot of CT can provide traction, which fundamentally address the problem difficult downward entry CT. operation principle, size, force, speed other technical indicators existing more cutting-edge types robots are analyzed, critica...

The occurrence of a brain abscess as a complication of halo traction and immobilization in the management of scoliosis is reported. Previous reports suggest that this complication is rare. Unique in this case is the development of an intracerebral abscess without skull perforation by the halo device and without evidence of contiguous spread of infection. Attention of clinical signs (headache) a...

We postulate that an equivalent continuum structure (ECS) of a single-walled carbon nanotube (SWCNT) is a hollow cylinder with mean radius and length equal to that of the SWCNT, and find the thickness of the ECS so that its mechanical response in free vibrations is the same as that of the SWCNT. That is, for mechanical deformations, the ECS is energetically equivalent to the SWCNT. We use MM3 p...

Callus distraction using bone segment transport systems is an applied process in the treatment of bone defects. However, complications such as muscle contractures, axial deviation and pin track infections occur in the treatment process using the currently available devices. Since successful treatment is influenced by the applied distraction force, knowledge of the biomechanical properties of th...
