Un anno di monitoraggio microclimatico in una sala della Pinacoteca Nazionale di Ferrara: problematiche di gestione ambientale e conclusioni

The article deals with the microclimate monitoring of a room in the national picture gallery of Ferrara, started in May 2006 for a term of twelve months. This work was aimed to draw a general and complete picture of the microclimate conditions in which paintings are subjected. Two paintings on wooden tables, representing “Coronation of the Virgin” and “St. John the Evangelist”, dated XV century, have been subjected to several investigations like the study of EMC (equilibrium moisture content) and its variations during all months of the year, and illuminance levels on pictorial surfaces to evaluate the suitability of lighting system of the museum. Solutions are suggested to create a suitable environment for the good conservation of works of art

Assessment of Energy Chains for Distributed Generation: Agricultural and Thermoeconomic Analyses within Emilia-Romagna Region

The process which includes production, collection, carriage and transformation of biomass into renewable fuels and then into energy (both electrical and thermal) involves a large number of decisions to select the most efficient chain. In this paper, the contribution margin of four different energy chains is evaluated both in terms of profits and energy gain per unit of cultivated surface. Four widely cultivated crops in Europe (corn, rapeseed, soybean and sunflower) are considered as feedstock. Four technologies are taken into consideration as conversion plants: (i) anaerobic digestion with internal combustion engines, (ii) direct combustion with Organic Rankine Cycle, (iii) gasification with internal combustion engines, and (iv) straight vegetable oil combustion within internal combustion engines
