A portable X-ray fluorescence device for in situ analyses of mural paintings

Within the context of a research program for studying with nondestructive methods the preparation and realisation techniques of mural paintings used in the Roman age, a portable ED-XRF device for elemental analysis has been set up. Preliminary tests have been carried out on two Roman mural paintings belonging to the Baia Archaeological Complex (Naples). Datable to different periods, the two paintings show different manufacturing and conservation states, thus representing a good test for verifying the ED-XRF device capability. In situ and laboratory measurements, performed on materials of different origin and nature, have permitted the determination of the pigments and the recognition of pollution traces

Lingue in contatto nel sistema penitenziario italiano: la ricerca DEPORT

Ormai da molti anni i fenomeni migratori che interessano la penisola italiana hanno prodotto una massa critica di immigrati che non può più essere ignorata e che ha apportato modifiche nello spazio linguistico italiano, come ricordato in Benucci, Grosso (2015). Nel contesto penitenziario, all’interno del quale, secondo i dati del Ministero della Giustizia, ad oggi i detenuti stranieri rappresentano circa il 32% circa del totale e appartengono a 140 nazionalità diverse, con il conseguente potenziale plurilingue e pluriculturale che ne deriva e che determina una situazione di “superdiversità” del tutto peculiare in tale contesto. Il contributo è volto ad illustrare tale situazione a partire dai dati della ricerca DEPORT, realizzata negli anni 2011 - 2015
