THE FORMULATION OF SOUND TRANSMISSION PROBLEMS THROUGH THE BOUNDARIES OF THREE-DIMENSIONAL MEDIA AND THROUGH PLATES

The formulation of sound transmission problems through the boundaries of three-dimensional media and through plates

Introduction.Modern physical models for calculating the propagation of plane longitudinal waves through media boundaries, based on the conditions of continuity of sound pressure and vibrational velocity, are implemented wella color charm 050 cooling violet only with normal wave incidence.In all directions of wave propagation other than normal, the

Substituted pteridinones, pyrimidines, pyrrolopyrimidines, and purines as p90 ribosomal S6 protein kinase-2 (RSK2) inhibitors: Pharmacophore modeling data

The RSK2 kinase is a downstream effector of the Ras/Raf/MEK/ERK pathway that is aberrantly active in a range of cancer types and has been recognized an anticancer target.The inhibition of RSK2 kinase activity would disrupt multiple pro-cancer processes; however, there are few RSK2 inhibitors.The data have been obtained for a series of pteridinone-,
