This DL=0V, Qarray DC=0V example shows the structure of impurities in erythromycin estimated from fragment ions generated by in-source CID. Erythromycin (major component) The multi-sequence mode permits several other methods within a single analysis, such as CID, positive/negative ion switching modes, and SCAN/SIM modes.

Giovanni ContiniLa Resistenza a Firenze tra celebrazione e attualizzazione politica Negli ultimi anni il tema della memoria ha preso sempre più campo negli studi sulla storia politica recente1. Si sono infatti messe in evidenza le trasfor-mazioni che la memoria di eventi particolarmente significativi subisce di anno in anno, di decennio in decennio, afferrata dal discorso politico nel suo progres-sivo mutare. Così la memoria stessa finisce per diventare oggetto storiografico, perché il modo attraverso il quale si parla di quegli eventi, e li si descrive da par-te della stampa, fornisce allo storico importanti informazioni indirette su come vada mutando non solo il discorso politico alto, quello della proposta generale, ma, direi, la sensibilità sociale per la politica, il ruolo insomma dei suoi temi nel gioco della sociabilità e della vita quotidiana.
