Nuovi coating ibridi (multi)funzionali per l’imballaggio.
Materiali ibridi organici-inorganici a struttura nanocomposita possono trovare interessanti applicazioni come coating in diversi settori. In questo articolo vengono illustrate alcune delle loro caratteristiche e potenzialità come coating funzionali (multifunzionali) per l’imballaggio alimentare. Un contributo che sembra promettente per lo sviluppo di imballaggi attivi e/o intelligenti

La prosa armena medievale come testimone del francese del Levante: osservazioni sulla fonetica dei prestiti francesi in armeno di Cilicia
Cilician Middle Armenian prose works contain a significant number of loanwords from French. The variety of French that must be considered the source of these loanwords is Outremer French, i.e. French as spoken in Near East in the Crusader States. The article provides a detailed analysis of the phonetic characteristics of these French loanwords in Middle Armenian. Thanks to its very rich inventory of graphemes, the Armenian alphabet reflects in a very accurate way the phonetic of the French words and therefore the French loanwords in Middle Armenian can be considered a very important witness for the knowledge of the phonetics of Outremer French
Tradizione e ricezione della prosa agiografica, con un caso di studio: il volgarizzamento fiorentino della Legenda Aurea
Il saggio descrive e analizza la tradizione manoscritta e la ricezione del volgarizzamento fiorentino trecentesco della "Legenda Aurea" di Iacopo da Varagine e pubblica in edizione critica e con commento, due agiografie volgarizzate (Callisto e Clemente).The paper describes and analyzes the manuscript tradition and the reception of the fourteenth-century Florentine vulgarization of the "Legenda Aurea" by Iacopo da Varagine and publishes a critical edition, with commentary, concerning two vernacular hagiographies (Callisto and Clemente)
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
OXYGEN PERMEABILITY OF NOVEL ORGANIC-INORGANIC HYBRID COATINGS
The oxygen barrier properties of composite materials, consisting of a 45 μm thick LDPE substrate coated by a thin layer (0.7-1 μm) of nanostructured hybrid organic/inorganic materials based on SiO2 and polyethylene-polyethylene glycol (PE-PEG) block copolymers, obtained via a sol-gel technique have been characterized at 35°C and 50°C
Macro and micro-logistic aspects in defining the parts-feeding policy in mixed-model assembly systems
The handling activities within mixed-model assembly systems deal with two different logistic levels of the production environment. The micro-logistic level includes movements of parts across each assembly station due to pick to assembly activities. The macro-logistic level includes movements of parts within the supermarket and to deliver the stock-keeping units to the assembly stations. The most frequently adopted part-feeding policies, i.e., kanban system and kitting system, strongly influences both logistic levels with opposite effects. The former continuously refills the assembly stations; the latter prepares and delivers kits of components for each product. Moving from kanban to kitting system the time spent at the macro-logistic level increases. On the contrary, the time spent in part handling at the micro-logistic level decreases when moving from kanban to kitting system. Effective trade-offs are encouraged. This paper analyses the two introduced part-feeding policies, including hybrid possibilities, through an operative total handling time comparison model. The findings from five industrial cases belonging to different sectors and a global simulation analysis are discussed. Conclusions about the impact of some of the most important logistic variables of the production system to the whole performances drive the industrial practitioners in the part-feeding policy selection
