Approche responsable pour le patrimoine : coopération, participation, documentation / Approccio responsabile al patrimonio architettonico: cooperazio…
2014
Nel quadro del Programma Italie Tunisie, l’esperienza del Progetto APER viene introdotta con riferimento ai diversi livelli e alle opportunità della cooperazione: tra realtà transfrontaliere, tra istituzioni dello stesso Paese e tra studiosi di diverse discipline. Passando ai contenuti scientifici, dopo aver illustrato il campo di applicazione e le potenziali ricadute, si pone l’accento sul tema dell’integrazione tra salvaguardia e valorizzazione, come sintesi teorica e operativa degli obiettivi del Progetto APER. Seguendo l’evoluzione dell’approccio al patrimonio architettonico, dall’origine dello stesso concetto allo sviluppo degli obiettivi della conservazione prima e della valorizzazion…
Inoculum of Indigenous Microalgae/Activated Sludge for Optimal Treatment of Municipal Wastewaters and Biochemical Composition of Residual Biomass for…
2022
In this work, municipal wastewater was treated with microalgal/activated sludge consortia. We aimed at obtaining a positive interaction between the microalgae and the heterotrophic bacteria and identifying the best combination for bioremediation purposes. A strain of Chlorella sp CW2 employed in this work was isolated from AS and molecularly characterised in this work for the first time. This strain and another previously isolated strain (Chlorella sp Pozzillo) were inoculated alone and in combination with AS in different ratios in wastewaters. Microalgae/activated sludge growth curves were obtained by using a UV–vis spectrophotometer and a fluorimeter to distinguish the contribution of the…
Des compétences artistiques aux compétences professionnelles
2010
Les écoles supérieures d'art certifient des qualifications complexes et aux devenirs imprédictibles. Les études sur l'insertion professionnelle des diplômés des écoles d'art (DNSEP) menées jusqu'ici se sont attachées à décrire la qualité de leur insertion. Dans cette recherche, la réflexion porte sur la valorisation des compétences acquises en formation dans le contexte d'exercice professionnel. Les diplômés des promotion 2003 et 2005 occupant un emploi artistique au moment de l'enquête sont ainsi réinterrogés 4 à 6 ans après leur sortie de formation.
Thermal kinetics for the energy valorisation of polylactide/sisal biocomposites
2018
[EN] The thermal stability and decomposition kinetics of PLA/sisal biocomposites was discussed to evaluate the suitability of their use in energy recovery processes such as pyrolysis and combustion. The influence of the addition of sisal up to 30%wt, the presence of coupling agent, and the atmosphere of operation, i.e. inert or oxidative was discussed by means of multi-rate linear non-isothermal thermogravimetric experiments. All biocomposites showed a mean high heating value of 15 MJ/kg indicating their suitability for energy recovery processes. The thermal requirements of PLA/sisal decomposition were assessed in terms of onset decomposition temperature and apparent activation energy. A mi…
Material valorisation of amorphous polylactide. Influence of thermo-mechanical degradation on the morphology, segmental dynamics, thermal and mechani…
2012
[EN] This paper reports the effects of multiple mechanical recycling on the structure and properties of amorphous polylactide (PLA). The influence of the thermo-mechanical degradation induced by means of five successive injection cycles was initially addressed in terms of macroscopic mechanical properties and surface modification. A deeper inspection on the structure and morphology of PLA was associated to the thermal properties and viscoelastic behaviour. Although FT-IR analysis did not show significant changes in functional groups, a remarkable reduction in molar mass was found by viscometry. PLA remained amorphous throughout the reprocessing cycles, but the occurrence of a cold-crystalli…
Valorisation of urban green areas for producing renewable energy and biochar as growing substrate of Sicilian aromatic and nutraceutical species in a…
2020
This work is aimed at evaluating the possible building up of a gasifier for the energy valorisation of residual biomass deriving from urban areas and their surroundings. The area and the volumes of supply and economic convenience have been determined by implementing a GIS-based geographic method to the localisation and quantification of non-uniform elements of plant biomass. The pyrolysis and gasification processes of the lignocellulosic biomass obtained from pruning and maintenance operations of the urban and ornamental green include the production of a residual amount of biochar. The biochar can be used in agriculture as a soil improver and a substrate alternative to peat in the sustainab…
Polylactide-based self-reinforced composites biodegradation: Individual and combined influence of temperature, water and compost
2018
[EN] Self-reinforced polymer composites (SRCs) are proposed as a suitable alternative for composite development, based in the combination of a polymeric matrix and a polymeric fibre made of the same polymer. SRCs based in polylactide (PLA) could be fully biodegradable and their valorisation routes could presumably be assimilated to those for neat PEA. In this sense, the aim of this study was to develop new self-reinforced PLA-based composites and ascertain their biodegradability. For this purpose, PLA-based SRCs were obtained through a thermo-compression procedure and their biodegradability corroborated under standard conditions (ISO 20200). Moreover, a deep study of the effect of the diffe…

Il presente contributo propone l'analisi di alcuni strumenti giuridici offerti dall’autonomia privata in ambito societario, in modo da permettere all’imprenditore – in tutte le ipotesi in cui quest’ultimo intenda determinare, prima della sua morte, la successione dell’azienda di famiglia – di pianificare in modo efficace il passaggio generazionale, avvantaggiando o sfavorendo, a seconda dei casi, il trasferimento delle partecipazioni societarie, con il proposito di disinnescare i rischi di disgregazione dell’unità dell’impresa e di conflitti tra i membri della famiglia. This contribution proposes the analysis of some legal instruments offered by private autonomy in the corporate sphere, in …
