Ravenna from imperial residence to episcopal city: processes of centrality across empire
Full text linkL'articolo si occupa di studiare i processi con cui Ravenna ha saputo rinnovare tra il V e il IX secolo il proprio ruolo di "centralità" nelle dinamiche storiche dell'Italia tra la tarda antichità e l'alto medioevo
Boundary Marks and Space Organization in Early Byzantine Epigraphy
No full textIl saggio prende in esame la funzione degli 'horoi', i segni di confine iscritti su pietra, nell'età compresa tra il III e il IX secolo. Essi, sulla scorta di una attitudine culturale concernente il concetto di 'termine, limite' ereditata dall'antichità, anche nel mondo bizantino sono posti sotto la tutela di Dio e degli imperatori. Si esaminano anche le informazioni che dai cippi di confine sono desumibili circa l'idea dello spazio sociale e naturale
Social instability and economic decline of the Ostrogothic community in the aftermath of the imperial victory: the papyri evidence
No full textIl saggio prende in esame il destino della comunità ostrogota in Italia nel corso della guerra gotica, sulla base principalmente dei papiri Tjaeder, nello specifico il pap. Tjaeder 49, che viene ripubblicato con alcune congetture

Il patrizio Germano e la famiglia imperiale nel VI secolo
No full textIl saggio affronta la questione del ruolo dei discendenti di Germano, cugino di Giustiniano, nella storia politica di Bisanzio nel VI e VII secolo. Propone anche una identificazione del generale ritratto nel celebre 'Avorio Barberini' con lo stesso Germano

Conclusive Results of the European Project OPTIMA: Optimization of Perennial Grasses for Biomass Production in the Mediterranean Area
No full textThe European Project OPTIMA–Optimization of Perennial Grasses for Biomass Production in the Mediterranean Area (GA 289642, coordinated by the University of Catania)–was conceived with the ambitious aim of identifying and optimizing new strategies for the sustainable use of land in marginal Mediterranean areas particularly exposed to climate change. Curiously, although today the term “marginal land” is on everyone’s lips, there is no clear definition for it [1]. Generally speaking, marginal land is considered as a land of low-opportunity cost where it is not worth cultivating food crops; however, the degree of marginality remains vague and complex to estimate as it strongly depends on context and domain. Rabbinge [2], for example, provided an agronomic definition of marginal lands basing on crop growth, Van Orshoven [3] defined marginal land in terms of biophysical constrains, and the FAO [4] proposed an economic perspective of marginal land. An enlightening review article on the definition of marginal land has been submitted during the OPTIMA project by Soldatos and collaborators (under review)

Agri-energy chains: From field to land planning [Modelli produttivi agri-energetici: l’integrazione di filiera dalla scala aziendale a quella territoriale]
No full textA general consensus on bio-energy and renewable energetic sources is expressed by modern societies; at the same time, some concerns and uncertainties are related to the actual ecological and environmental standards that these new technologies are able to fulfill. The overall energy demand is permanently rising as the economic growth spread through new developing countries. The consciousness about the limited petroleum availability and the negative en- vironmental consequences related to fossil fuels exploitation, inevitably calls for a new global energy model based on a drastic improvement on energy use efficiency, energy savings and renewables. On this respect, biomass could play an important role to meet these new constraints and requirements.
The development of bio-energy needs a reliable biomass availability, a well organized and integrated chain-supply and reasonable costs of the biomass feedstock in order to be competitive with respect to conventional fossil-fuels. Different productive and distributive chain-supply can be depicted, at the large as well as at the local-scale; pros and cons can be identified for both, but locally produced bio-energy and “distributed” energy generation is mostly favored by general society and some stakeholders; it seems to better support landowners, rural economy and local market; at the same time, the environmental benefits seems to be higher. Rigorous evaluation procedures, such as “Life Cycle Assessment”, must be ordinarily implemented to proper compare such alternatives with each other and choose the one that fits better
