Sul decadimento delle onde di accelerazione in un fluido non viscoso entro una teoria termodinamica non stazionaria

Sergio Bressan (1982)

Atti della Accademia Nazionale dei Lincei. Classe di Scienze Fisiche, Matematiche e Naturali. Rendiconti Lincei. Matematica e Applicazioni

Similarity:

In according to a recent thermodynamic theory proposed by G. Grioli we consider the growth of acceleration waves in a non viscous fluid. We determine the solutions for the growth of a plane or spherical wave advancing into the fluid in mechanical but not in thermal equilibrium.

Sulla propagazione e sull'evoluzione di onde nei solidi termoelastici. Nota I

Similarity:

According to a thermodynamic theory proposed by G. Grioli, we consider the problem of determining the solutions for the growth of acceleration waves in an elastic body. At first we determine a property of the velocities of waves propagation and we determine some limitations for the free energy; then we resolve the above mentioned problem for the «small» waves working on the iperacceleration waves.

After writing the equations which characterize the thermomechanics of hyperelastic continua subject to small transformations according to a recent hypothesis on the heat flux vector, we study the spherical thermomechanical waves.

Influenza di alcuni neurofarmaci sull’agamia degli Elosomatidi

Anna Stagni, M. Luisa Sini-Rubatta, Vincenza Morini (1980)

Similarity:

Observations prolonged for two months show how aged Aelosoma viride specimens increase their asexual reproductive power. Treatment of this species with some neuropharmacological agents (norepinephrine, amphetamine, reserpine) demonstrate that: 1) noradrenaline excites the growth by increasing the number of segments; 2) amphetamine excites the growth but inhibits asexual reproduction; 3) reserpine is strongly toxic; 4) growth and asexual reproduction appear as two partially separated...

Alcune considerazioni su una classe di sistemi del primo ordine quasi-lineari conservativi ed iperbolici di due equazioni in due variabili indipendenti

Domenico Fusco (1980)

Atti della Accademia Nazionale dei Lincei. Classe di Scienze Fisiche, Matematiche e Naturali. Rendiconti

Similarity:

In this paper we determine a class of first order quasi-linear hyperbolic systems in conservative form involving two independent and two dependent variables which are not deducible, in general, from a variational principle but can be reduced to a Godunov’s symmetric form [5], [6] where the coefficient of the field spatial derivative is a constant matrix. That enables us to extend to these systems several results obtained by G. Boillat in [8], [9] and concerning with shocks in quasi-linear...

Sui moti per eliche circolari in Meccanica dei plasmi

Giulio Mattei (1981)

Atti della Accademia Nazionale dei Lincei. Classe di Scienze Fisiche, Matematiche e Naturali. Rendiconti Lincei. Matematica e Applicazioni

Similarity:

In this paper we extend to Plasma Mechanics the study of the hydrodynamic steady motions in which the streamlines are circular helixes. The plasma is described by the magnetofïuiddynamic equations with the Hall effect. Velocity and magnetic fields (and, in correspondence, the pressure field) that make such motions possible are determined. So a class of exact solutions of the magnetofïuiddynamic equations with the Hall effect is pointed out.
