In practice, the submarine's major internal equipment is mounted to welded plating foundations, but submarine designers have been looking at the recent French innovation whereby the major internal equipment is mounted to a large truss/cradle structure through point supports. The focus of this research investigates the effects of radial point supports on the stability behavior of cylindrical she...

PURPOSE To determine in a cadaver model which, among 5 fixation methods for proximal interphalangeal (PIP) joint arthrodesis, has the greatest stiffness. METHODS Thirty-five cadaver digits were randomly assigned to 1 of 5 fixation groups: oblique K-wire with coronal intraosseous wiring, tension-band wire (TBW), dorsal plate, intramedullary linked screw (IMS), and 90/90 wiring (90/90W). Testin...

We investigate the cross-sectional buckling of multi-concentric tubular nanomaterials, which are called multiwalled carbon nanotubes (MWNTs), using an analysis based on thin-shell theory. MWNTs under hydrostatic pressure experience radial buckling. As a result of this, different buckling modes are obtained depending on the inter-tube separation d as well as the number of constituent tubes N and...

One of the most frequently overlooked injuries is neglected radial head dislocation, which is currently known as Monteggia fracture dislocation. Chronic radial head dislocation can result in elbow stiffness, deformity, persistent pain, and instability. In this report, we described an unusual case involving chronic radial head dislocation that was neglected for 15 years and secondary ulnocarpal ...

Objective To investigate the phenotypic relationships between aortic stiffness and left ventricular (LV) stroke volume (SV) and modes of deformation (longitudinal LD and radial -RD) at rest and stress, with preserved and compromised contractile capacity. Background Increased aortic stiffness, measured by pulse wave velocity (PWV), is linked to a range of cardiovascular (CV) risk factors and act...

As cardiovascular death remains major cause of death worldwide , there are growing needs for risk evaluation for cardiovas-cular event. Arterial stiffness, which refers to the rigidity of arterial wall, increases in the elderly person as well as patients with atherosclerotic disease. Based on the belief that increased vascular stiffness precedes atherosclerotic vascular event, there were attemp...

PURPOSE To compare the stability of a novel, nonspanning external fixator with a standard volar locked plate for treatment of unstable distal radius fractures. METHODS A simulated, unstable, extra- articular distal radius fracture was created in six matched pairs of fresh frozen human distal radii. One of each pair was treated with a nonspanning external fixator [Mirza Cross Pin Fixator (CPX)...

left atrial (la) distension has been demonstrated to be linked with aortic stiffness in different patient populations. three-dimensional (3d) speckle-tracking echocardiography (ste) seems to be a promising tool for volumetric and functional evaluation of the la. the aim of the present study was to determine whether correlations exist between 3dste-derived la volume-based and strain parameter...

The aim of the study was to find the optimum combination of materials and thicknesses to provide a tough, damage resistant multi-layer system with numerical methods to restore the damaged teeth. Extended Finite Element Method (XFEM) was used to assess the critical loads for the onset of damage modes such as radial cracks and plastic deformation in dental prostheses, which consist of a brittle o...

While central (carotid-femoral) foot-to-foot pulse wave velocity (PWV) is considered to be the gold standard for the estimation of aortic arterial stiffness, peripheral foot-to-foot PWV (brachial-ankle, femoral-ankle, and carotid-radial) are being studied as substitutes of this central measurement. We present a novel methodology to assess theoretically these computed indexes and the hemodynamic...
