this research develops thermo-elastic analysis of a functionally graded cylinder under thermo-mechanical loadings. heat conduction equation in cylindrical coordinate system is solved. thermal conductivity coefficient is graded along the radial direction. by considering a symmetric distribution of temperature, loading and boundary conditions, strain-displacement and stress-strain relations can b...

anatomical vascular variations are rare causes of carpal tunnel syndrome. an aberrant medial artery is the most common vascular variation, while an aberrant radial artery causing carpal tunnel syndrome is even more rare, with an incidence ranging less than 3%. this article reports a patient with compression of the median nerve at the carpal tunnel by an aberrant superficial branch of the radial...

one of the major problems in data envelopment analysis (dea) is to determine the projection of inefficient decision making units (dmus) into the efficient frontier. in conventional dea models, inputs and outputs of inefficient dmus alter arbitrarily for reaching to the efficient frontier. nevertheless, sometimes the ability of dmus is defined and restricted. moreover, there are situations in th...

many simulation algorithms (chemical reaction systems, differential systems arising from the modeling of transient behavior in the process industries and etc.) contain the numerical solution of systems of differential equations. for the efficient solution of the above mentioned problems, linear multistep methods or runge-kutta technique are used. for the simulation of chemical procedures the ra...

Introduction Loss of radius either due to trauma or infection results in a deformity resembling congenital radial club hand. This difficulty perform hand functions and cosmetic appearance is called acquired There are few case reports for the treatment this severe deformity, but there no proper guidelines management disease. From our experience, we decided provide Objectives To evaluate outcome ...

Neocortical neurons are produced by cell division of neural stem cells in the ventricular zone of the cerebral cortex. We investigated the production of neurons by infecting neuroepithelial cells with a modified GFP-recombinant adenovirus. The adenovirus DNA is inherited by only one daughter cell at each cell division and travels one way from the progenitor to the progeny. Since the ventricular...
