Optimization of end-of-life good disassembly using an Ant Colony System
No full textIn a modern productive scenario the problem represented by the tons of scraps daily produced in the industrialized countries is often face by recycling. In this paper a contribution to the improvement of the recycling process performed by the disassembly of end-of-life widely diffused goods is proposed.
An optimization methodology named “Ant Colony Optimization” (ACO) is proposed as an innovative tool for approaching the problem of detecting the best way in disassembling goods for recycling purposes. The implementation details have been presented, as well as the application in four meaningful case studies represented by typical widely diffused goods
Scaling up Three Dimensional Printing
No full textNew processes and machines are proposed in academia and on the market, down to the microscopic range. On a different side, manufacturing complex parts of large size by additive processes has still unexplored potential. This paper describes the patented 3DPrinting D-Shape technology, one of the few available to build parts up to 3 tons. Three sands have been tested, calcareous dolomite, granite and pozzolana (regolith-like) with pulverized MgO, under the action of an aqueous MgCl2 binder, focusing on the optimization of the inkjet parameters

The Lettere of Andrea Calmo: authorial artifices and historical reality
No full textopenNonostante l’edizione di Vittorio Rossi del 1888, la raccolta di "ingegnosi cheribizzi" e di "fantastiche fantasie" di Andrea Calmo è ancora avvolta da un certo mistero. L’autore, dissimulando la propria identità dietro alla “maschera” dell’umile pescatore veneziano, è stato in grado di offrire uno spaccato della cultura e della società nella Venezia cinquecentesca.
In particolare, è il quarto libro delle Lettere ad aver suscitato maggiore interesse tra gli studiosi ed i lettori: pubblicato nel 1566, a diversi anni di distanza dai primi tre, questo libro si distingue per il fatto che tutte le epistole sono indirizzate a delle donne immaginarie o realmente esistite.
In questa sede si propone, in primo luogo, uno studio della biografia del Calmo accompagnata da un’analisi del contesto storico-culturale della Venezia cinquecentesca; in secondo luogo, invece, viene proposto un commento di alcune lettere dell’ultimo libro dell’opera calmiana, che cerchi di far luce principalmente sull’aspetto linguistico e contenutistico del testo.Despite Vittorio Rossi's 1888 edition, Andrea Calmo's collection of "ingegnosi cheribizzi" and "fantastiche fantasie" is still shrouded in a certain mystery. The author, dissimulating his own identity behind the "mask" of the humble Venetian fisherman, was able to offer a cross-section of culture and society in sixteenth-century Venice.
In particular, it is the fourth book of the Letters that has aroused greater interest among scholars and readers: published in 1566, several years after the first three, this book stands out for the fact that all the epistles are addressed to women imaginary or actually existed.
Here we propose, first of all, a study of Calmo's biography accompanied by an analysis of the historical-cultural context of sixteenth-century Venice; secondly, however, a commentary on some letters from the last book of Calmo's work is proposed, which seeks to shed light mainly on the linguistic and content aspect of the text
Trusted Tales: Creating Authenticity in Literary Representations from Ex-Yugoslavia
No full textThis research deals with questions of authority and authenticity and how they are expressed, constructed, and appropriated within the Anglophone book market. It considers the body of literature written about ex-Yugoslavia since the 1990s Balkan conflicts by exiled writers from the region which has entered the international literary canon. Books’ routes from original publishers into English translation are discussed through practices of trust, one of the crucial social devices underpinning their exchange. Within these cross-cultural processes, the role of cultural brokers is crucial. Symbolic and cultural resources are specifically mobilised through their powerful author brands.
By exploring authenticity in the context of book publishing, I further look at how ideas and practices of community are employed and negotiated by writers and those who promote their books. My field is multi-sited and fluid, reflecting how different individual and national positions are enacted and performed through strategies ranging from unconscious dispositions to deliberate intentions. This research thus brings together ideas of the author as an authentic, representative voice together with exile as a position that grants them a new lease of relevancy in the post-socialist context.
Although ex-Yugoslav books occupy a ‘high end’ niche of the UK market, constrained by commercial as well as political, cultural, and institutional forces, in public discourse ideas of the ‘free market’ and ‘free speech’ are mobilised to produce various types of modernisation narratives. The (post)socialist production of literature is perceived as having to ‘evolve’ into a capitalist model: this would allow not only healthy competition and consumer choice but guarantee an individual writer ‘free speech’ as a basic human right. Therefore, the most general question this research raises is what kind of foreign literature gets translated into English, under what socio-cultural conditions and which politics of representation it serves within the project of world literature
SYSMET: SYSTEMS BIOLOGY OF MEMBRANE TRAFFICKING
No full textStudies on membrane trafficking have expanded massively over the last 40 years. During this time, research has led to an understanding of the molecular mechanisms underlying membrane trafficking pathways, providing crucial insights into several fundamental events. Although we have gained detailed knowledge about the molecular organization of membrane trafficking machineries there is a lack of a global view of its function, organization and regulation. In addition, many genes of the membrane trafficking machinery have been associated with diseases. In the majority of cases, disease manifestation is tissue-specific despite the ubiquitous expression of the causal gene. Explanations for this phenomenon may be found either in the specific requirements and demands of a cell within a given tissue or in differences in the expression of disease gene interactors.
The main aim of this project was to delineate sets of co-expressed membrane trafficking genes and proteins (membrane trafficking modules; MTMs) across tissues. For this purpose we curated a list of 1,261 genes that have been described as part of membrane trafficking machineries in different cellular organelles, around which we have developed a bioinformatics pipeline in order to address two specific questions:
a) are membrane trafficking genes organized in MTMs, defined as communities of co-expressed genes, and are they associated with general cellular functions?
b) do disease genes have specific membrane-trafficking co-expressed communities in those tissues that are affected by the disease?
To address these questions we used data from the Genotype-Tissue Expression (GTEx) project, a catalog of human tissue-specific gene expression patterns obtained from “non-diseased” tissues sampled from recently deceased human donors.
With regards to the first question, we analyzed the expression patterns of the trafficking genes in twenty-five different tissues and used weighted correlation network analysis (WGCNA) to derive highly preserved MTMs. We have analyzed in more detail one that includes genes apparently involved in collagen secretion. Instead for the second question we applied differential co-expression before the WGCNA to generate tissue-specific MTMs to understand how specific membrane trafficking gene modules might be organized in human tissues
