L’autoreprésentation féminine dans la bande dessinée pornographique
2017
What happens when feminine authors investigate porn-comics and draw themselves in it ? Self-depiction of feminine authors conveys something original in a field where it usually is a way to express a private fantasy. From feminist comics of the 70s to the most recent porn comics, authors’ bodies are not sex objects anymore, they are the subject of a narration. Self-depiction is a new material for porn-comics and gives sincerity to the stories, it may be a way to express political views. Self-fantasy, sex confession or physical metamorphosis are the multiple ways self-depiction provides the feminine author to strengthen her authorship. Implicitly those self-depicted porn-authors draw up an in…
The safety of an industrial archaeological heritage
2013
The present paper analyses an underground and inactive quarry of calcarenite, which belong to a localised area called Cave di calcarenite in Contrada Cuccidenna that has been recognised as a typical example of industrial archaeological heritage. The study of this typical quarry is finalised to the preservation and safe fruition of this site, which represents the history of manufacturing technologies of rocky ashlars. Rock samples from the pillars have been collected and, at first, a petrographic characterisation has been performed. The strength parameters have been estimated by means of triaxial and isotropic compression tests. Through a finite element analysis, the mechanical characterizat…

Solar neutrino physics with Borexino
2018
We present the most recent solar neutrino results from the Borexino experiment at the Gran Sasso underground laboratory. In particular, refined measurements of all neutrinos produced in the {\it pp} fusion chain have been made. It is the first time that the same detector measures the entire range of solar neutrinos at once. These new data weakly favor a high-metallicity Sun. Prospects for measuring CNO solar neutrinos are also discussed.
Some Considerations on 3-D and 2-D Numerical Models for the Assessment of the Stability of Underground Caves
2014
The application of numerical modeling to the analysis of the stability of both natural and man-made underground caves is rapidly increasing due to the availability of powerful numerical codes, that can account for either continuum or discontinuum behavior of the rock masses. Numerical methods allow to overcome traditional methods for cave stability analysis that assume too simplified geometrical, geological and geomechanical conditions. Further, they are also able to assess the potential failure mechanisms of underground systems. On the other hand, the application of numerical methods requires availability of a detailed geo-structural survey of the cave, as well as a proper geomechanical ch…
Examples of anthropogenic sinkholes in Sicily and comparison with similar phenomena in southern Italy
2013
A sinkhole, occurred in June 2011 and related to an underground quarry in the eastern sector of Marsala, is described in this paper as a case study (Figure 2). The site was selected for the availability of topographic data of the underground quarry, prior to the formation of the Abstract Anthropogenic sinkholes affect several built-up areas of Sicily (southern Italy) representing a great risk to people, buildings, and infrastructures. These phenomena are generally associated with the presence of ancient underground quarries for the extraction of calcarenite rock, used for building or ornamental materials. These quarries were poorly constructed and abandoned throughout history.
