A NEW SAUROPODOMORPH DINOSAUR FROM THE EARLY JURASSIC OF PATAGONIA AND THE ORIGIN AND EVOLUTION OF THE SAUROPOD-TYPE SACRUM.

A new sauropodomorph dinosaur from the Early Jurassic of Patagonia and the origin and evolution of the sauropod-type sacrum.

The origin of sauropod dinosaurs is one of the major landmarks cardinals 3.14 flash sale of dinosaur evolution but is still poorly understood.This drastic transformation involved major skeletal modifications, including a shift from the small and gracile condition of primitive sauropodomorphs to the gigantic and quadrupedal condition of sauropods.Re

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 09gi shades eq conditions of continuity of sound pressure and vibrational velocity, are implemented only with normal wave incidence.In all directions of wave propagation other than normal, the continuity conditions
