We derive the equations of motion for an N-body system in the Einstein–Cartan gravity
theory at the first post-Newtonian order by exploiting the Weyssenhoff fluid as the spin …

This is a book on seismology dealing with advanced aspects of wave propagation in
complex media. It can also be viewed as a book on mathematical modelling, wherein the …

R In the companion book (Continuum Mechanics Using Mathematica) to this volume, we
explained the foundations of continuum mechanics and described some basic applications …

We numerically investigate the stress distribution of a paste when an external oscillation is
applied. The paste memorizes the oscillation through plastic deformation. Due to the plastic …

Under improper transformations, the traditional transformation laws for cross products, the
permutation tensor, and rotations are incorrect. For a cross product, using a counter …

We propose an analytic C 1 solution of the hydrodynamic equations for a main-sequence
star in stationary and spherically symmetric conditions. We reach this result starting from …

Starting from integral balance laws, a model based on nonlinear ordinary differential
equations (ODEs) describing the evolution of Phosphorus cycle in a lake is proposed. After …

We have already remarked that the simplified models of continuum mechanics (perfect and
viscous fluids, elastic systems, etc.) do not always accurately describe the complex …

We critically analyze the models of a main-sequence star based on polytropic gases. First,
we put in evidence that the hypothesis of polytropic gas is compatible with the constitutive …
