Eshelby has shown that a glide dislocation can move without radiation of energy at 2 p of the shear wave speed. It is also known that the same velocity plays a special role in shear crack propagation. This result has not received wide attention in the past due to lack of experiments and numerical simulations of transonic defects. Recent experiments on transonic shear fracture and molecular ...
The main goal is to analyze the influence of cracks on azimuthal variations amplitude. We restrict our investigation a single set vertical, circular, and flat cavities aligned along horizontal axis. Such are embedded in either transversely isotropic background with vertical symmetry axis (VTI) or surroundings. employ effective medium theory obtain orthotropic VTI homogenised medium, respectivel...
In this paper, we studied the viscoelastic behaviors of isolated aortic elastin using combined modeling and experimental approaches. Biaxial stress relaxation and creep experiments were performed to study the time-dependent behavior of elastin. Experimental results reveal that stress relaxation preconditioning is necessary in order to obtain repeatable stress relaxation responses. Elastin exhib...

The current case report describes a case of Intraoperative progressive hemodynamic failure in a patient undergoing orthotropic liver transplantation. Rescue transesophageal echocardiography was used to facilitate rapid diagnosis of a iatrogenic acute pericardial tamponade, resulting from a suture penetrating the pericardium through the right hemi diaphragm. This potentially lethal complication ...
To overcome current limitations of valve substitutes and tissue substitutes the technology of tissue engineering (TE) continues to offer new perspectives in congenital cardiac surgery. We report our experiences and results implanting a decellularized TE patch in nine sheep in orthotropic position as aortic valve leaflet substitute. Establishing the animal model, feasibility, cardiopulmonary byp...
