EXTENSION OF TWO-PHOTON SPECTROSCOPY TO THE VACUUM ULTRAVIOLET USING SYNCHROTRON RADIATION
No full textSynchrotron radiation has been used for the first time in two-photon spectroscopy. The experimental apparatus, built at the ADONE storage ring in Frascati, and using a Q-switched Nd:YAG laser as a powerful source is presented. Space and time superposition of the beams is discussed extensively. Testing of the apparatus has been performed by measuring the two-photon absorption spectra of KCl and NaCl
Synthesis and characterization of new ferrocene, porphyrin and C<inf>60</inf> triads, connected by triple bonds
No full textThe 2,12 pyrrole positions of meso-tetraphenylporphyrinwere functionalized through triple carbonecarbon
bonds by ferrocene and C60 giving new electron donor-acceptor triads which have been characterized and
studied by photophysical methods
Optical investigation on dye-doped sol-gel glasses
No full textWe have investigated the optical properties of the 3,3'-diethyloxadicarbocyanine iodide (DODCI) dye incorporated in a number of sol-gel glasses in order to study the interaction between the trapped molecule and the host matrix. The differences found in both the absorption and the photoemission spectra demonstrate that the excitation processes of the dye molecule are influenced by the chemical reactivity and the degree of porosity of the surrounding network. We have found that while the molecular photoisomerization is quenched in all the matrices, for the modifications of the electronic excited states the high rigidity of the purely inorganic silica matrix is required. Conversely, the possibility of chemical attacks to the molecular conjugate chain seems to increase in the hybrid organic/inorganic ormosil matrices. © Societò Italiana di Fisica
Freedom of Religion in the Workplace: the Current State of the Art
No full textThe Author examines domestic, European and international jurisprudence on freedom of religion in the workplace. Two main findings have been reached: there is a trend towards uniform solutions based on the reasonable accomodation test and this method of solving conflicts should be implemented by company collective agreements or by preventive, unilateral, policies

New technologies in the workplace: impacts on labour law
No full textIn a very deconstructive labour law scenario that we are facing now (globalization of supply
chains, fissuring of work, spread of platform providers, individualisation and de-unionisation,
decentralisation of collective agreement, ecc.), how could workers’ rights be protected during the
digital age? Is it better to dismantle the standard employment contract and construct in its place a
broader foundation of economic security for all as somebody proposed, or is it better to move
with great precaution towards an updating of concepts and definitions, keeping in force the actual
system of protection with some limited revisions? The answer argued by the Author is in favour
of the second choice
Gli effetti del regolamento europeo GDPR sulla disciplina del trattamento aziendale dei dati del lavoratore
No full textIl saggio, attraverso una ricostruzione del quadro normativo di riferimento e degli orientamenti delineati dalla giurisprudenza e dai Garanti per la privacy in ambito europeo e nazionale, illustra i principi contenuti nel GDPR ed applicabili nelle fasi di instaurazione e gestione del rapporto di lavoro.The essay, through a reconstruction of the legislative framework and the guidelines outlined by jurisprudence and by European and national data protection Authorities, examines the principles contained in GDPR and applicable in setting and managing the working relationship. The Author notices how the working relationship makes always more use of computer tools which allow, directly or indirectly, the employee activities to be monitored. Thus, the compromise between opposite interests (privacy protection and corporate assets protection) can be guaranteed through a privacy compliance enhancement within the company policies, with the intent of preventing or at least reducing any kind of illicit data processing
Study of the refractive index of microscopic glass beads by light-refraction analysis
No full textThe refractive index of submillimeter glass beads has been measured by means of a novel, to our knowledge, procedure with reference liquids that does not require close index matching and therefore avoids the use of toxic compounds for high-index glasses (i.e., n ≥ 1.8). The method is based on the analysis of the light refracted by a monolayer of beads in comparison with ray-tracing simulations. For the three different types of glass beads investigated a satisfactory fit is achieved by the assumption of a radial variation of the refractive index inside the beads. This is ascribed to the tensile and compressive stresses originating inside the beads during rapid solidification of the glass. © 1997 Optical Society of America
