Memorie urbane. Nuove modalità di racconto della storia dei luoghi
No full textCome si può valorizzare lo spazio pubblico restituendo nel modo più coinvolgente la storia del suo passato con un approccio interdisciplinare tra architettura e comunicazione multimediale? Il fine è tener viva la memoria dei luoghi affinché le tracce degli accadimenti siano leggibili e condivise.
A partire da questa domanda si è sviluppato il lavoro presentato nella mostra 1943 - 2018 Memoria e spazio pubblico. 12 progetti per ricordare il bombardamento di San Lorenzo a cura di Cecilia Cecchini e Maurizio Di Puolo che ha avuto luogo a Roma alla Casa della Memoria e della Storia (11-16 Maggio 2018) e all’Ex Dogana (18-29 Luglio 2018) in occasione delle celebrazioni previste per il 75° anno dalla data dell’evento.
La mostra presenta il lavoro di ricerca progettuale svolto dagli studenti nell’Atelier di Exhibit Design del Corso di Laurea Magistrale in Design Comunicazione Visiva e Multimediale, prendendo come riferimento il quartiere San Lorenzo di Roma che nell’estate del 1943 venne profondamente danneggiato dai bombardamenti che causarono più di 3000 morti. In particolare il tema ha riguardato la progettazione di un memoriale diffuso che fosse capace di comunicare, attraverso modalità contemporanee e coinvolgenti, quanto accaduto. Oggi, infatti, le conseguenze di quelle devastazioni pur essendo ancora in parte visibili, sono segni evidenti solo per chi ha vissuto o conosce quei tragici avvenimenti, ma illeggibili per chi frequenta le sue strade senza conoscerne la storia.
Il contributo dello scritto di Cecilia Cecchini è una riflessione relativa alla valorizzazione della memoria dei luoghi e, più in generale, su un aspetto fondamentale degli spazi pubblici, quello della loro identità.How can we make the most of public space, communicating the history of its past in the most engaging way, using an interdisciplinary approach that spans architecture and multimedia communication? The aim is to keep the memory of places alive so that the traces of events may be both visible and shared.
This question gave rise to a project that was presented at the exhibition entitled 1943-2018 Memoria e spazio pubblico: 12 progetti per ricordare il bombardamento di San Lorenzo (Memory and Public Space: 12 projects commemorating the bombing of San Lorenzo), curated by Cecilia Cecchini and Maurizio Di Puolo, which took place at the Casa della Memoria e della Storia in Rome (11-16 May 2018) and the ex-Dogana exhibition space (18-29 July 2018) during celebrations commemorating the 75th anniversary of the event.
The exhibition presents project-based research work carried out by students attending the Exhibit Design workshop as part of the Master’s degree course in Multimedia and Visual Design Communication, which focused on the San Lorenzo district of Rome, heavily damaged by bombing raids that killed over 3,000 people in the summer of 1943. The workshop’s theme particularly focused on designing a multi-location memorial that could communicate what happened using modern, engaging means. This is because the results of that devastation, though still partly visible, are now only obvious to those who witnessed it first-hand or those who know about those tragic events, whilst they are invisible to those who pass through the district without knowing its history.
What follows is therefore a reflection on the promotion of the memory of places and, in general, a fundamental aspect of public space: its identity
Interventi di riabilitazione post-sisma nel centro storico di L'Aquila: un approccio GIS, metodologia e prospettive applicative
No full textIl lavoro ha tratto ispirazione dalla condizione nella quale versa il centro storico del capoluogo abruzzese a quattro anni di distanza dalla catastrofe del 6 aprile 2009 e propone un approccio alla gestione complessiva della situazione ricorrendo a uno strumento di georeferenziazione open source in grado di fornire risposte a più scale spaziali (e/o temporali) di intervento attraverso procedure idonee a garantire la gestione dei processi dell’emergenza e della ricostruzione nei loro aspetti evolutivi.
Principali finalità del lavoro sono da un lato l’elaborazione di strategie miranti alla ‘riattivazione urbana’, dall’altro la produzione di un sistema di monitoraggio del costruito costantemente aggiornato e utile sia ai professionisti incaricati del restauro dei singoli manufatti sia alle amministrazioni che vogliano intraprendere politiche di prevenzione sismica a lungo termine mediante l’elaborazione di mappe del rischio ed altri documenti per il governo del territorio urbano sotto il profilo della sicurezza sismica.
Una prima fase del lavoro di tesi ha affrontato la ricerca delle cause e dell’entità del danneggiamento notevolmente esteso, incrociando i vari aspetti rilevanti, come l’indagine del sottosuolo, la vulnerabilità del costruito - studiata anche attraverso il censimento e l’indagine delle tipologie murarie e della loro qualità, ed altri.
A ciò ha fatto seguito la creazione di un vasto database in cui sono stati immagazzinati i dati relativi ai 505 aggregati presenti all’interno della zona A (il centro storico ovvero l’area di studio), dalle caratteristiche anagrafico/funzionali degli stessi alla loro agibilità, passando per il danno registrato secondo la scala EMS, le informazioni relative alla loro costituzione strutturale, la collocazione o meno in zona rossa ecc.
Strati informativi di particolare interesse sono quelli relativi al rilievo georiferito di ogni singola opera di messa in sicurezza presente su ogni aggregato e agli esiti di agibilità.
La base informativa costruita, estesa attraverso una cospicua quantità di dati fotografici e abachi anch’essi georiferiti, ha avuto una duplice utilità: la creazione di grafici di analisi e bilancio per una comprensione a più livelli di complessità della condizione del centro storico (aggregati in zona rossa, livelli di danneggiamento, funzioni compromesse ecc.) oltre che l’elaborazione di strategie per la ridefinizione e il monitoraggio della zona rossa nonché di supporto alla viabilità e alla cantierizzazione delle aree della città.
Il lavoro ha in nuce molteplici possibili sviluppi futuri: da un più efficace monitoraggio delle opere di presidio (che mostrano a ormai 4 anni dal sisma situazioni ricorrenti di degrado) a una auspicabile gestione informatizzata dei dati per una loro fruibilità da parte della cittadinanza e un loro costante sviluppo e aggiornamento nel tempo; ciò nella convinzione che solo elevando sempre più il livello di conoscenza sul costruito si possano elaborare strategie operative sia globali che mirate aventi alla base un utilizzo sempre più efficace e trasparente delle risorse.
Le metodologie elaborate mostrano la loro validità nella constatazione che il caso aquilano è soltanto uno degli innumerevoli possibili campi d’applicazione, laddove esse risultano applicabili a qualunque realtà, urbana o territoriale, interessata da calamità e/o tale da richiedere la gestione di una molteplicità di dati tra loro interconnessi per controllarne e migliorarne le dinamiche evolutive.The work was inspired by the condition in which is the heart of the city of L’Aquila (centre Italy) 4 years after the seism of April 6, 2009. It proposes an approach to the complex situation management using an open source georeferencing instrument, able to give solutions at several spatial/temporal intervention scale thanks to methods apt to guarantee the control of the emergency and of the reconstruction.
Main purposes of the work are the processing of strategies oriented to the “urban reactivation” on the one hand, the realization of an always updated buildings monitoring system advantageous at multiple levels on the other: this may be interesting not only for all freelance professionals projecting single buildings restoration, but also for local administrations starting seismic-prevention policies.
The first phase dealt with the research of the damage causes and importance intersecting many significant aspects, such as the subsoil survey, the buildings vulnerability, also examined through the typology and quality masonry census, and so over.
The results obtained were the basis for the creation of a database storing the attributes of the 505 aggregates consituting the inner city of L’Aquila (“A zone” according to the town plan). It is divided into 5 sections containing respectively geographic-functional, structural technology, damage, practicability, provisional measures data.
This platform was implemented by a huge quantity of photographic references and georeferenced indexations: in particular, after a diffused urban survey, it was possible to classify the most common masonry works and all kind of provisional measures employed and to place them on the map through photos.
This had a double utility: at first the elaboration of analysis diagrams for understanding the complexity of urban reality at multiple levels (aggregates belonging to the red zone, damage conditions, compromized functions ecc.), then the planning of “seismic-urban” strategies to redefine and monitor the gradual extension changing of the red zone or to support the viability for the next construction sites intallation.
This method shows a lot of development potentialities: for istance a more efficacious provisional measures screening (showing evident decay signs, after 4 years), but also an advantageous computerized data management in view of their fruition from the citizens; all this is realized in the certainty that, only through a continued elevation of the “knowledge level” of the buildings it is possible to study operational strategies both global and focused, starting from a more efficacious and effective use of resources.
The methodologies show also that the case of L’Aquila is only one of the innumerable possible application field, because they could be tested on whichever urban or territorial reality, interested by natural calamity or needing a multiplicity data management to control and improve certain evolving dynamics.
For its characteristics of originality and in-depth analysis, this study was graded with highest honours and publication recommended by the academic board
The Basilica of Santa Maria di Collemaggio in L’Aquila: Modern Provisional Measures
No full textThe case in analysis is Santa Maria di Collemaggio, the church symbol of the town of L’Aquila and the most important
example of Romanesque style in Abruzzi, tragically damaged by the earthquake in 2009. The following paper starts with an accurate
analysis of the Basilica, whose historical, stylistical cultural characteristics make it an unicum in the whole urban environment. The
authors tried to identify in which way these values have been compromised or altered after the earthquake through several analysis
(surveys, historical researches etc.) aiming at the recognition of collapses, the cracks profile, the structural transformations caused by
the provisional measures: the goal is to provide a kind of Basilica “cognitive manual” that will be useful for the future interventions.
This first analysis allowed to understand many aspects: on the one hand, the constructive phases and which damages were caused by
past careless interventions of restoration, drawing attention to the vulnerability elements of the Basilica; on the other hand, the
innovative technologies and materials of the post-seismic provisional measures and their exact location

Digital Transformation in Europe
No full textThis chapter focuses on the challenge of lifelong learning and guidance of new paradigms for higher education institutions. Universities are expected to play a new important role in providing innovative teaching, learning processes, and counselling services to help people navigate the recurrent transitions throughout their lives. Based on these assumptions, this chapter aims to provide: (a) a theoretical framework which illustrates the recent evolutions of organizational models and the implications of digital transformation on them, with particular reference to universities;
(b) an overview of the state-of-play of European policies and initiatives related to HE, with particular attention to the evolution, progress, and development of the HE field in terms of digitalization (online as well as blended teaching and
learning); (c) a focus on the role of digital skills concerning competences for life, with the presentation of the main European competences frameworks
Physiology and genetics of candidate probiotic strains relevant to animal health and production
No full textProbiotic microorganism inclusion in feeds is emerging as a popular
and potentially valuable tool in the practice of human and
veterinary medicine and animal production. Recent research work
has contributed to clarify the appropriate probiotic organisms,
appropriate doses and conditions that are potentially treatable
with probiotic strains in several farm animal species. The appealing properties of probiotics include the ability to reduce antibiotic use,
the apparently very high index of safety, and the public’s perception
about ‘natural’ or ‘alternative’ therapies. Probiotic organisms
must survive the acidic environment of the stomach and resist
to the digestion process, adhere to the intestinal lining, colonize
the intestinal tract and produce beneficial factors and inhibit
pathogens (disease-causing bacteria). Other properties such as
immunomodulation and modulation of metabolic activities are also
desirable. Probiotics must be identified at the strain level from
faecal and intestinal samples by means of molecular tools (DGGE,
Real-time PCR analysis) and testing must be performed on individual
strains
DOE analysis of the rheological data of shear-thickening fluids for puncture-resistant composite shells
No full textThe dilatancy (Shear-thickening) is a time-independent rheological behaviour exhibited by some non-Newtonian fluids. These fluids manifest a surge in the apparent viscosity with an increase in the shear rate. If these fluids are encapsulated, they can be used to manufacture high-end stab resistance inserts (Cecchini et al., 2018) [1]. In the first part of this work, a comparison between the rheological performance of different shear-thickening fluids (STFs) based on nanosilica dispersed in glycols is presented. This analysis attempts to investigate the combinations of fillers and carriers with the highest energy-absorbing capabilities, among the various glycol-based colloidal STFs. In the second part, the influence of the composition of the STF on its rheological properties is analyzed statistically. The statistical analysis is performed by evaluating the interaction between the main design variables of the fluids (filler dimension, weight-to-weight ratio and molecular weight of the carrier). Finally, the puncture resistance of a composite system obtained by encapsulating the previously manufactured shear-thickening fluids in a polymeric shell is analyzed by means of a high-speed puncture test. This test is performed on the mockup of a tyre tread containing the best performing STF. The results showed that the use of the STF core increased the resistance to puncture by 20% as compared to the same volume of tyre tread material. Furthermore, the STF hermetically sealed the pierced sample, even when the tyre mockup was inflated at high internal pressures
Progettazione e realizzazione di smart materials a controllo passivo per applicazioni acustiche = Design and manufacturing of passive materials for acoustic applications
No full textThe Dilatancy (Shear-thickening) is a time-independent behaviour exhibited by some non-Newtonian fluids, consisting in an abrupt increase in the apparent viscosity with the shear rate. These fluids can be used to design novel composite materials with increased sound insulating properties: in order to optimize their rheological properties, a refined model of their constitutive behaviour is necessary. The objective of the first part of the thesis is the optimization of the rheological behaviour of these fluids. A coupled steady/oscillatory shear rheological approach was employed in order to derive a novel master curve for the material: this allows to predict the best combinations of fillers and carriers capable of granting the final product with the highest sound insulation capabilities. Finally, during the second part of the thesis, numerical models for the sound insulation of the fully assembled smart material were developed and validated with experimental sound insertion loss tests
A fiber-optic genosensor for Brettanomyces detection
No full textYeast is essential in the production of fermented foods, but can also cause food spoilage in poor fermentation management or post-process contamination. That most dreaded by winemakers is the non-pathogenic yeast B. bruxellensis which leads to the development of unpleasant aromas. Currently, this is detected in wine using both traditional and molecular techniques (delaherche et al., 2004). The development of molecular methods has improved the sensitivity and specificity of yeast identification tests. Recently, optical fibers have become an important part of sensor technology in clinical, pharmaceutical and industrial applications (Espinosa et al., 2007)
