Presence and distribution of the brown bear (Ursus arctos) in Friuli Venezia Giulia, from 2004 to 2011, through the non-invasive genetic monitoring a…

After having disappeared at the beginning of 1900, the brown bear has started in a late 1960s a slow process of recolonization of the north-eastern Alps, through an expansion of Dinaric population. At the end of the 1990s the University of Udine began the occasional monitoring of the species and from 2004 non-invasive genetic monitoring became systematic. In the last 8 years 217 hair traps have been activated in the region to monitore: Natisone Valleys, the Julian and Carnic Alps and Prealps. Twenty-six hair traps were monitored in all years, whereas 40 were observed only in 2004, 2007 and 2011. The 26 hair traps constantly monitored from 2004 to 2011 showed 17% of average success of hair’s…
Noninvasive monitoring of polymer curing reactions by dielectrometry
2011
A microwave sensor system for the noninvasive monitoring of the curing process of a thermoset material placed inside a metallic mold is described. The microwave sensor is designed as an open-ended coaxial resonator with a curved surface adapted to the mold inner shape. The analysis of the microwave resonator comprises a recently developed method for deembedding the effect of coupling network in overcoupled resonators, so the range of permitted measurements encompass both low and high dielectric losses of polymeric materials. Results show that noninvasive, continuous monitoring of the microwave dielectric properties of the thermoset material can be performed in real time, allowing one to che…
Proceeding Book of 12th European Symposium on Religious art, Restoration & Conservation

Fundamental contribution to filling out the condition reports of the work of arts involved in temporary exhibitions is provided by non-invasive investigation techniques. Investigation, carried out before and after the movement, allow to collect objective data to monitoring the surface or structural alterations and defining the state of conservation, representing an important moment of deepening of knowledge. Generally, these aspects often are left to photographic documentation and observations by conservators and curators. An example of good practice is represented by the case of the Saint Gregory Polyptych (Antonello da Messina, 1473) belonging to the Regional Museum of Messina (Italy). Th…
