This paper presents the effect of centrifugal load in functionally graded (FG) hollow sphere subjected to uniform magnetic field. Analytical solution for stresses and perturbation of the magnetic field vector are determined using the direct method and the power series method. The material stiffness, the magnetic permeability and the density vary continuously across the thickness direction accor...

axial vibration effect of shell particles on dynamic stability of a cantilevered cylindrical shell under an axial follower force was addressed. in spite of free-ended shells, the reduced axial force under this effect cannot be derived analytically. instead, an approximate method was proposed based on the fact that the static (and harmonic) axial deformation under an axial load in a free-ended b...

In this study, Mg alloy-based composites (MMC: metal matrix composite) with uniaxially oriented continuous SiC fibers were fabricated using a low-pressure infiltration method. Next, the influence of Al particles as promoter on interfacial reaction between and alloy was investigated by means scanning electron microscopy (SEM) energy dispersive X-ray (EDX) analysis. presence particles, β-Mg17Al12...

Segments of dog carotid artery were held at in-situ length and studied in vitro after excitation of the muscle with norepinephrine and after poisoning of the muscle with potassium cyanide. In-situ length corresponded to a longitudinal strain of .57 ± .02 relative to the unstretched length. The longitudinal elastic modulus was about 4.1 X 10 dyn/cm at in-situ length and zero transmural pressure....

A feedback mechanism between different tissues in a growing bone is thought to determine the bone's morphogenesis. Cartilage growth strains the surrounding tissues, eliciting alterations of its matrix, which in turn, creates anisotropic stresses, guiding directionality of cartilage growth. The purpose of this study was to evaluate this hypothesis by determining whether collagen fiber directions...

OBJECTIVE We report our experience with 93 consecutive pulmonary artery reconstructions during pulmonary lobectomy with regard to morbidity, mortality, and long-term survival. METHODS Clinical records of all patients who underwent lobectomy with partial or circumferential pulmonary artery resection in a single institution during an 8-year period were reviewed retrospectively. RESULTS Lobect...
