The authors interpreted these findings as suggesting that knowledge of morphology necessarily precedes knowledge of semantics in this aspectual domain, and that the acquisition of

In this paper, we see the dependance of entropy gradient is necessary for isentropic waves of acceleration along the interfaces: the fact the internal energy depends not only on

An important thermodynamical potential is related to the mixture volume free energy [32–34]. At a given temperature, the volume free energy is associ- ated with the spinodal
