Giusta causa di licenziamento tra legge, contrattazione collettiva e sindacato del giudice = Justified dismissal between law, collective bargaining and Judge check
No full textL’articolo tratta dei licenziamenti disciplinari per giusta causa, nozione che viene ricostruita dall’Autore analizzando le diverse letture che di tale canone hanno dato la contrattazione collettiva e la giurisprudenza secondo le maglie più o meno larghe loro attribuite dall’evoluzione normativa della disciplina sui licenziamenti individuali. L’Autore si concentra, in particolare, sull’assetto dei ruoli che la contrattazione collettiva e la giurisprudenza hanno assunto nelle più recenti riforme, quali la Riforma Fornero e il Job Act.The article debates about disciplinary justified dismissals, concept reconstructed by the Author analysing the different interpretations given about this rule by collective bargaining and jurisprudence. These interpretations show link more or less wides depending on the legal development about the dismissal. The Author’s focus is, expecially, about the connections between collective bargaining and jurisprudence after the latest reforms, as the Fornero Reform and the Job Act
Asbestos health hazard: A spectroscopic study of synthetic geoinspired Fe-doped chrysotile
No full textThe chrysotile fibres toxicity appears correlated to the redox activity of iron present in the chrysotile
structure. In fact the generation of reactive oxygen species and other radicals appears catalyzed by iron
ions and closely related to Fe ions organization in specific crystallographic sites having a capability to
activate free radical generation. The Fe substitution to Mg and/or Si in the chrysotile structure appears
important for asbestos health hazard investigation. Infrared and Raman spectroscopic analyses have been
utilized to investigateMg and/or Si ions replacement by Fe ions in chrysotile structure as a function of the
Fe doping extent. Geoinspired synthetic chrysotile at different Fe doping extents has been obtained as
unique phase by hydrothermal reaction in the presence or not ofmetallic Fe in the synthetic environment.
The results highlight that Fe can replace both Mg and Si, differently modifying the chrysotile structure
as a function of the Fe doping extent and the Fe doping process. The contemporary iron substitution into
the octahedral and tetrahedral sheets reveals an appreciable increase of the dehydroxylation temperature
which occurs at higher temperature than for iron-free sample. The results highlight the role of Fe
substitution in the asbestos structure influencing the health hazard of biological systems
Micro-Raman spectroscopy applied on oriented crystals of fluoro-edenite amphibole
No full textFluoro-edenite crystals from Biancavilla, a mineral characterized by various cations in different crystallographic sites, have been studied with Electron Microprobe Analysis (EMPA) and micro-Raman spectroscopy. The spectroscope used in this study was fitted with an optical microscope equipped with two polarizers and a rotating plate with a vernier, allowing precise orientation of the sample. The Raman spectra were acquired after precisely aligning the crystals with respect to the incident laser beam. The spectra recorded are discussed in relation to the chemical data from EMPA analyses. This investigation suggests that a similar methodological approach can be used to discriminate other fibrous amphiboles which can be difficult to identify by conventional techniques
