In the first part we examine the present carriages, their types and their distribution; then, in the light of these clearly discernible facts, we intend to interpret the sources concerning, on the one hand, the wheeled vehicles from Protohistory to the Mughal period, and on the other hand, the changes introduced by the transport revolution of the middle of the 19th century. It shows that, prior to the British period, the northern plains of India were favoured with a variety of vehicles for travelling and for goods traffic, many of them with a rudimentary form of suspension, while in the Deccan, most of the country carts were heavy, ill-constructed and not fit for distant journeys. The reason why the people of Hindusthan showed much greater ingenuity than those of the Deccan concerning the construction of carts is perhaps due to the fact that, over the centuries, greater attention was given there to roads and their maintenance than on the peninsula: at least since Asoka, the sovereigns of the Gangetic Plain were interested in the question of roads, and particularly in the good condition of the Grand Trunk Road and the axes leading to the Gulf of Cambay.Collection Indologie ;126.Carriages and cartsCarriages and carts.688.6Deloche Jean641090NjHacINjHaclBOOK9910725993703321Contribution to the history of the wheeled vehicle in India2883870UNINA05345nam 2200721 450 991013136940332120230808211707.01-5231-1055-41-119-04429-41-119-04430-81-119-04419-7(CKB)3710000000437525(EBL)2075007(SSID)ssj0001515676(PQKBManifestationID)12550798(PQKBTitleCode)TC0001515676(PQKBWorkID)11482722(PQKB)11238827(PQKBManifestationID)16203435(PQKB)20901317(MiAaPQ)EBC2075007(DLC) 2015014391(Au-PeEL)EBL2075007(CaPaEBR)ebr11071168(CaONFJC)MIL804023(OCoLC)912237441(EXLCZ)99371000000043752520150710h20162016 uy 0engur|||||||||||txtccrSolvent effects in chemistry /Erwin Buncel, Robert A.

It begins with basic thermodynamics and kinetics, building on this foundation to demonstrate how a more detailed understanding of these effects may be used to aid in determination of reaction mechanisms, and to aid in planning syntheses. Consideration is given to theoretical calculations (quantum chemistry, molecular dynamics, etc.), to statistical methods (chemometrics), and to modern day concerns such as ""green"" chemistry, where utSolvationChemical reactionsSolventsSolvation.Chemical reactions.Solvents.541/.34Buncel E.956763Stairs R.

Temi ;38.9788867282791 8867282794 9788867283606 886728360X L'importanza del ruolo del presidente della Repubblica nell'equilibrio dei poteri emerge fin dalla nascita dell'Italia democratica - ben presente nel dibattito in Assemblea costituente e poi nel testo della Costituzione - e tuttavia la storiografia solo recentemente ha "scoperto" la centralità di questo tema per analizzare le trasformazioni dei costumi repubblicani nel secondo dopoguerra, vale a dire il tessuto civico del paese nel rapporto tra istituzioni e cittadini. Le ricerche che qui si presentano si propongono dunque una prima ricognizione per osservare i comportamenti dei presidenti della Repubblica e decifrarne i codici di comunicazione nell'esercizio delle loro prerogative, nel tentativo di cogliere il diverso "stile" politico con cui si impersona il potere. Ecco allora delinearsi altrettanti terreni di ricerca: le relazioni tra il capo dello Stato e i cittadini; l'uso dei rituali civili e dei simboli nella costruzione dell'identità nazionale; l'immagine (istituzionale e privata) dei presidenti nell'opinione pubblica; il ruolo dei media (stampa, fotografia, radio, cinema, televisione, Internet); l'influenza esercitata dal Quirinale nel delineare l'immagine internazionale dell'Italia. La riflessione storica deve inoltre dare qualche risposta a pressanti questioni di attualità: la personalizzazione della politica, le retoriche populistiche, la crisi di legittimazione del potere nelle democrazie occidentali.PresidentiItaliaPresidenti della RepubblicaItalyPolitics and government20th centuryPresidentsItalyBiography & autobiographyPolitical scienceItaliaPresidenti della Repubblica945.092Ridolfi Maurizio1957-118596Ridolfi Maurizio1957-Presidenti della Repubblica, le istituzioni e i cittadini, l'Italia e l'Europa (Conference)(2013 :Viterbo, Italy)BOOK9910229890003321Presidenti4171653UNINA
