In this study, the attenuation of coda waves has been estimated in the western part of Iran plateau using single backscattering method. Coda wave attenuation was estimated at seven central frequencies (fc = 1.5, 3, 4.5, 6, 9, 12, 18 Hz) and eigh... see more

The paper reports an algorithm to analytically solve one of the problems in the mechanics of elastic bodies, which is associated with studying the natural vibrations of a composite two-stage plate whose concave part is smoothly aligned with the part of a ... see more

Background: Of the various techniques developed for the treatment of gum recession, the current innovation in the use of platelet rich plasma (PRF) has been applied to the treatment of root-end closure procedures. Purpose: This study analyzed the effect o... see more
