Opera and Law: Critical Notes
No full textThis paper intends to provide some methodological tools to explore the many different connections between law and opera. While the paper may of course be set in the context of studies about law and humanities, it intends to address some specific issues typical of the opera context. It proposes three different pathways: studies about legal problems as described in opera plays (“Law in opera”); analyses about the regulation of opera itself (copyright, etc., collectively referred to as “Law on opera”); and a broader, less theoretically-constrained field of connections between the two worlds, covering parallels between the circulation of legal and operatic traditions, regulations of new interaction between the audience and the staging, etc
Preliminary Results on a New Safety Road Barrier Made Completely of Wood.
No full textThe aim of the research is a new safety road barrier made completely of wood.
Road safety barriers usually are made of steel or concrete. Wood is a material with a
complex structure, whose main features are anisotropy and hygroscopicity. It also
possesses greatly different mechanics characteristics between the longitudinal direction
and the tangential and radial direction. In Europe, road safety barriers have to pass crash
tests required by EN1317 before their location. So in this research, a new type of barrier
has been designed and modelled and has been simulated the impact with a vehicle using
the software Ls-Dyna, which follows EN 1317 prescriptions. A parametric analysis has
been conducted by the authors, to examine how humidity can modify mechanical
characteristics of wood and so performance of the new barrier. The results appeared
interesting: the new barrier satisfied all requirements prescribed by the Regulation and the
parametric study highlighted that ASI (Acceleration Severity Index) index vary with the
humidity but its values were always below the limit imposed by EN 1317.This study
represents only one step of the research which needs more data to individuate a
correlation between humidity and ASI index, and a real scale test to calibrate the mode
