Adhémar Jean Claude Barré de Saint-Venant (23 August 1797, Villiers-en-Bière, Seine-et-Marne – 6 January 1886, Saint-Ouen, Loir-et-Cher) was a mechanician and mathematician who contributed to early stress analysis and also developed the unsteady open channel flow shallow water equations, also known as the Saint-Venant equations that are a fundamental set of equations used in modern hydraulic engineering.  The one-dimensional Saint-Venant equation is a commonly used simplification of the shallow water equations.  Although his full surname was Barré de Saint-Venant in mathematical literature other than French he is known as Saint-Venant.  His name is also associated with Saint-Venant's principle of statically equivalent systems of load, Saint-Venant's theorem and for Saint-Venant's compatibility condition, the integrability conditions for a symmetric tensor field to be a strain.

By complying of these measures, the support of ECB was implicitly conditioned by massive purchase of Italian bonds on the secondary market. Italian Sommelier Association, 'AIS' ("Associazione Italiana Sommelier ", sometimes also as known as "Italian Association of Sommeliers ") is an Italian non-profit organization founded in Milan on July 7, 1965, officially recognised and legally acknowledged by the Italian government on April 6, 1973, with formal President of the Republic decree #539 in 1973.

"Zoroastre"'s premiere in 1749 was not a success; despite the magnificence of the staging, it failed to compete with Mondonville's new "opéra-ballet" "Le carnaval du Parnasse".  Rameau and Cahusac decided to rework the opera completely before offering it to the public again in 1756.  Acts 2,3 and 5 were heavily rewritten and there were several modifications to the plot.  This time audiences took to the opera, although the critic Melchior Grimm was withering about Cahusac's libretto: "In "Zoroastre" it is day and night alternately; but as the poet...cannot count up to five he has got so muddled in his reckoning that he has been compelled to make it be day and night two or three times in each act, so that it might be day at the end of the play".  "Zoroastre" was chosen to open the new Paris opera house on January 26, 1770, the old one having burned down in 1763.  It was also translated into Italian by Casanova for a performance in Dresden in 1752, although some of Rameau's music was replaced by that of the ballet master Adam.  Its first modern revival was in a concert version at the Schola Cantorum, Paris in 1903.  The United States premiere of the opera was staged by Boston Baroque (then known as Banchetto Musicale) at Harvard University's Sanders Theater under conductor Martin Pearlman in 1983 with Jean Claude Orliac in the title role and James Maddalena as Abramane.
