The purpose of this study is to calculate the effect elastic wall a hollow channel Jeffrey's fluid by peristaltic flow through two concentric cylinders. inside tube cylindrical and outside regular in shape sine wave. Using coordinates assuming very short wavelength relative width its length using governing equations for Jeffrey’s Navier-Stokes equations, results problem are obtained. Through Ma...

Volumetric integral and integro-differential equations are considered that describe problems of diffraction by three-dimensional bodies with given macroscopic permittivity magnetic permeability, as well on free vibrations such bodies. Similar obtained for waveguide structures: hollow shielded waveguides dielectric filling, (optical beamguides), photonic-crystal waveguides. Dominantly stationary...

This article documents experiments performed in ewes to design an artificial larynx. The artificial larynx is composed of a hollow, porous tube that elongates the trachea and is capped with a valve that acts as a laryngeal sphincter. Through an industrial collaboration, our team developed a porous biomaterial that can be colonized by cervical tissues. This biomaterial has been used in animals t...

OBJECTIVE To introduce a new modified technique for radial artery catheterization. MATERIALS AND METHODS A prolongated needle was made by using routine Vasocan Braunule needle and 1 ml syringe. A table of random digits was used for randomization of 32 interns. 14 interns were involved in group T and 18 interns were in group M. Each intern accomplished 20 cases. Then 640 patients were divided ...
