Aree industriali dismesse: problema ambientale o risorsa sostenibile?
2012
This article highlights the complex theme of industrial areas, which, for a variety of reasons have been abandoned, something that has aroused the interest on the part of many disciplines. Here the Author outlines a strategy to regenerate and re-develop these areas, backed up by the sustainability of recovery interventions, eco-compatible technology and new materials.
Rhizoanalysis of Sociomaterial Entanglements in Teacher Interviews
2022
AbstractThis chapter explores how the entangled relationship between the material and social in teachers’ perceptions of change can be empirically investigated. More specifically, the chapter adopts a DeleuzoGuattarian rhizoanalytic assemblage approach and the notion of becoming to capture the dynamic and fluid nature of social and material affects. The study re-analyses three teacher interviews from data sets originally collected for different research purposes but with the theme of change relevant in each interview. The findings show that rhizomatic analysis and approaching interviews as assemblages can yield important insights about material realities. For example, they indicate how teac…
Eine Analyse von vier Lehrwerken für Deutsch- und Schwedischunterricht
2015
Tämän tutkielman tarkoituksena on selvittää, kuinka autenttisuus näyttäytyy yläkoulun saksan ja ruotsin oppikirjoissa. Tutkimuksen taustalla on saksan ja ruotsin heikentynyt asema koulukielinä: saksan lukijamäärät ovat laskussa ja ruotsin kielen asemasta pakollisena kielenä keskustellaan jatkuvasti. Yhtenä ratkaisuna ongelmaan on ehdotettu oppilaita innostavia ja motivoivia, autenttisia oppimateriaaleja ja menetelmiä. Autenttisuus kieltenopetuksessa on monimuotoinen ilmiö, jonka toteuttaminen käytännössä on monen opettajan mielestä haastavaa ja aikaavievää. Suurin osa suomalaisista kieltenopettajista turvautuukin työssään oppikirjoihin, joten halusin selvittää, missä määrin autenttisuus huo…

Influence of anodizing surface treatment on the aging behavior in salt-fog environment of aluminum alloy 5083 to fiber reinforced composites adhesive…
2021
The present work aims to evaluate how an innovative and eco-friendly anodizing process with tartaric-sulfuric acid (TSA) bath and a pore widening in an aqueous solution of NaOH 0.1 M can improve the durability in marine environment of co-cured adhesive joints between an aluminum alloy (AA 5083) and fiber (i.e., glass or basalt)-reinforced composite substrates. The aging was carried out by exposing samples to salt-fog spray conditions (5 wt.% NaCl) for 30, 60 and 90 days in a climate chamber, in accordance with ASTM B117. In order to get further insights on the aging behaviour of bonded joints, neat matrix was also exposed to the same environment for 60 days. Quasi-static mechanical tests an…
Sulla nozione di bene giuridico in diritto privato
2012
Il saggio affronta il nodo della nozione di bene giuridico in diritto privato e tenta di offrire una revisione critica delle principali teorie, rileggendo il rapporto tra bene e cosa. La nozione di bene che ne emerge consente di risolvere con maggiore coerenza problemi assai attuali quali il trattamento giuridico dei c.d. beni immateriali e la disciplina dei c.d. beni comuni
New Polylactic Acid Composites Reinforced with Artichoke Fibers
2015
In this work, artichoke fibers were used for the first time to prepare poly(lactic acid) (PLA)-based biocomposites. In particular, two PLA/artichoke composites with the same fiber loading (10% w/w) were prepared by the film-stacking method: the first one (UNID) reinforced with unidirectional long artichoke fibers, the second one (RANDOM) reinforced by randomly-oriented long artichoke fibers. Both composites were mechanically characterized in tensile mode by quasi-static and dynamic mechanical tests. The morphology of the fracture surfaces was analyzed through scanning electron microscopy (SEM). Moreover, a theoretical model, i.e., Hill's method, was used to fit the experimental Young's modu…
MECHANICAL, RHEOLOGICAL AND THERMAL EVALUATION OF POLY(LACTIC ACID) (PLA)/MICRO FIBRILLATED CELLULOSE (MFC) PLASTICIZED BIOCOMPOSITES PRODUCED WITH F…
2022
The use of Micro Fibrillated Cellulose (MFC) as filler for polymeric matrices attempts an increasing interest both in academia and industry. In this framework, encouraging results have been obtained using plasticizers, as dispersing aids, during twin-screw extrusion that optimizes the process parameters and avoid MFC agglomeration. In this work, two commercial typologies of waterborne solution of MFC (Exilva and Celish) were melt-compounded in a PLA matrix through semi-industrial twin-screw extruder and calendered, producing films of 150 μm thickness. These films were mechanically and thermally characterized, moreover the migration of the plasticizer along the time was evaluated through ana…
