Here, in Purgatorio XVI, Marco Lombardo, after stating that the misrule of the popes led the world to the sin, articulates Dante's view of the Empire and Papacy as separate authorities and cites the instance of Rome at the pagan Age, when Rome used to possess two autonomous institutions to drive mankind both towards the material happiness and the spiritual one (vv. 106 ff. "soleva Roma, che '1 buon mondo feo/due soli aver, che l'una e l'altra strada/facean vedere, e del mondo e di Dio"). The image of"two suns" also returns in the III Book of De Monarchia by Dante. Here Dante, inquiring into the relationship between "the two greatest luminaries", that is the Roman Pontiff and the Roman Prince, wonders if the authority of the Roman ruler descends directly from God or from someone of His ministers. For Dante the Emperor, whose authority is given to him directly by God, does not depend on the Pope, but the Emperor is absolutely independent of the Pope.展开更多

In the work, the main aim was to obtain biogas, made from at least 50% methane, and a digestate that can be used in the field of agronomy, from the anaerobic digestion of the substrates. The tests were carried out by digesting different mixtures of the two-phase pomace, mulberry leaves and mud civil wastewater (pre-digested) in a batch system and in anaerobic mesophilic conditions (35 ~C). The substrates were properly homogenized in order to obtain mixtures of known and uniform composition. The initial and final STi (Total Solids) and initial SVi (Volatile Solids), the concentration of chemical oxygen demand and total phenols were measured and the process yield (m3/t SV) was quantified with standard procedure. The objectives of the study were the analysis of microbial biodiversity developed during fermentation of mixtures based products and the microbial communities corresponding to Eubacteria, Archaea and Fungiwas analyzed. The suitability of the digestate for agronomical use was evaluated by estimating pathogens bacteria that may be present and by index of inhibition of plant organisms model.展开更多
