Gestione energeticamente efficiente di bruciatori a gas metano

Il funzionamento efficiente dal punto di vista energetico di un impianto di processo termico riscaldato ametano dipende in larga misura dalla qualità e dalla costruzione dei bruciatori utilizzati. In base ad esempipratici viene dimostrato in che modo possa essere individuato un aumento inutile del consumo, verificatosi acausa di una errata regolazione del bruciatore o di pressioni oscillanti dei servo mezzi di alimentazione.Tali fenomeni possono essere evitati in maniera efficace e permanente, adottando delle contromisure, in parteanche semplici. Inoltre viene illustrata la diretta dipendenza dell’efficienza energetica dalla dimensione dellasuperficie del tubo radiante

Universities, Academies and Sciences in Italy in the Modern Age

In order to explain the centrality of the university system in Italy it may be useful to examine the relations between the universities and the many academies, which were in a somewhat precarious position since they had been unable to obtain continuous public financing. From this point of view the crucial period in Italy was to be in the two decades of Napoleonic government (1796-1814), when the whole education system was financed by the State; not only the universities, but also the academies, particularly the Istituto Nazionale and the Atenei civici. Because of these public funds an increasing number of scientists were able to live on their research and their professions as engineers, doctors, university professors, or public functionaries. In this way the contemporary Italian scientific community was created. During the Restoration of the old governments, however, many scholars were obliged to leave Italy; some, like Ottaviano Fabrizio Mossotti in Argentina and Agostino Codazzi in Venezuela, took part in furthering science in South America
