Vetromattoni innovativi per componenti traslucidi multifunzionali

2017

A partire dal 2006, presso l’Università degli Studi di Palermo è stata avviata una ricerca finalizzata ad indagare le potenzialità di materiali e sistemi tecnologicamente avanzati per l’ottimizzazione energetica e l’incremento prestazionale degli elementi di captazione della luce naturale integrati nell’involucro edilizio. In particolare, negli anni, l’attenzione è stata posta su un prodotto ben noto ai più come “vetrocemento”, di “gran moda” negli anni Trenta del Novecento -in Italia così come in Europa e in Nord America- ravvisando nella sua stessa conformazione -due conchiglie di vetro “saldate” a caldo con una intercapedine interposta- le potenzialità per una ulteriore implementazione d…

Open design. Pratiche di progetto e processi di conoscenza

2013

In un momento caratterizzato da una profonda crisi di sistema, che investe l’economia e gli assetti produttivi ma anche identità e valori, si moltiplicano le riflessioni e le posizioni che indicano nel ritorno ad una rinnovata dimensione del fare una via possibile per riavviare processi economici innovativi, che ridiano centralità alle persone e alle comunità. Recuperare il “saper fare” artigianale, al tempo dell’intelligenza collettiva e connettiva, dell’internet delle cose, dell’open source e dei fablab, può essere occasione di rinascita economica e sociale, individuale e collettiva, di più generazioni di progettisti e innovatori, minacciati negli ultimi anni dallo “spettro dell’inutilità…

Palermo si cura. Pratiche culturali di mutuo soccorso come risposta alle fragilità della città (post)pandemica

2023

In un quadro di riferimento in cui la crisi è globalizzata ma diseguale e in mancanza di un sistema di welfare capace di rispondere alle urgenze dei contesti e dei gruppi sociali più marginalizzati, una risposta ai nuovi bisogni sociali ed individuali è stata offerta da reti solidali e da pratiche di mobilitazione dal basso che svolgono un ruolo di agency territoriale, spesso indipendentemente o in assenza di Istituzioni. Nel contesto palermitano un impegno agito da una pluralità di soggetti culturali già attivi sul territorio, riuniti in un’assemblea pubblica (Palermo si cura), durante il periodo del primo lockdown hanno dato vita ad azioni di mutuo soccorso per rispondere all’emergenza ec…

Settore ICAR/21 - UrbanisticaIn a framework in which the crisis is globalized but unequal and in the absence of a welfare system capable of responding to the urgencies of the most marginalized contexts and social groups a response to the new social and individual needs has been offered by networks of solidarity and from bottom-up mobilization practices that play a role of territorial agency often independently or in the absence of institutions. In the Palermo context a commitment made by a plurality of cultural subjects already active in the area gathered in a public assembly (Palermo si cura) during the period of the first lockdown gave rise to mutual aid actions to respond to the economic emergency and social and offer a proposal to cure the fragility of the city based not on charity but on the claim of a political dimension of collective action. Starting from the analysis of initiatives such as "Un sorriso per Ballarò" and "Abbiamo un (bi)sogno" the contribution analyzes the role the incidence and the fragility of these experiences in providing answers - often filling gaps - to a general interest and how these processes of value creation can hopefully contribute to the construction of local government policies capable of addressing emerging issues.

The Lean Urban Policies’ Design A values-centered method for sustainable urban planning.

In these past years, the necessity and urgency has emerged for policies tied to an alternate development to be efficiently applied, and not limited to single operations. The policies must be defined by a clear and effective method of action.
 Starting by investigating what are the relationship among human being, built environment and natural sources, in fact, we think it is possible to enrich the sustainable urban planning policies with new contents and possibly, new tools. By describing the frame, the objective is to define the most effective method, to be able to convey an effective project action and governance for the territory, to achieve predefined social and energy based objectives. …

STUDIO DI UNA FRIZIONE MAGNETOREOLOGICA PER AUTOVEICOLI

2013

Dopo un’accurata ricerca bibliografica sui fluidi magnetoreologici, il loro comportamento ed impiego, si è passati alla progettazione di una frizione magnetoreologica per autoveicoli. Considerando le caratteristiche di coppia trasmessa e potenza, il dispositivo è stato dimensionato tenendo presente i vincoli di ingombro del veicolo preso in esame. Sottoponendo il dispositivo ad analisi magnetostatica agli elementi finiti, si è determinato l’andamento delle linee di flusso del campo magnetico nel meato di fluido e nelle zone di maggior interesse, calcolando la coppia teoricamente trasmessa dall’innesto.È stato anche eseguito il confronto delle prestazionifra una frizione MR ed una frizione t…

Settore ING-IND/14 - Progettazione Meccanica E Costruzione Di MacchineAfter a thorough literature search on magnetorheological fluids their behavior and use it has gone to the design of a magnetorheological clutch for motor vehicles. Considering the characteristics of transmitted torque and power the device is dimensioned taking into account the constraints of space of the examined vehicle. Subjecting the device to magnetostatic finite element analysis it was determined the trend of the flow lines of the magnetic field in the gap of fluid and in areas of greater interest calculating the torque transmitted theoretically by the clutch. The performance comparison between a traditional clutch and a MR clutch was also performed pointing out that the MR clutch presents shorter response times with high energy savings. The study carried out shows that the device is well suited to a vehicle with automatic or robotic or otherwise with very short response times but requires a control system for the starting the vehicle.

Dense solid–liquid off-bottom suspension dynamics: Simulation and experiment

2009

Dense solid–liquid off-bottom suspension inside a baffled mechanically stirred tank equipped with a standard Rushton turbine is investigated. Dynamic evolution of the suspension from start-up to steady-state conditions has been determined by both visual experiments and computational fluid dynamics (CFDs). A classical Eulerian–Eulerian multifluid model (MFM) along with the “homogeneous” k–ε turbulence model is adopted to simulate suspension dynamics. In these systems the drag inter-phase force affects both solids suspension and distribution. Therefore, different computational approaches are tested in order to compute this term. Simulation results are compared with images obtained from the re…

The influence of sludge retention time on mixed culture microbial fuel cell start-ups

2017

Abstract In this work, the start-ups of air-cathode microbial fuel cells (MFCs) seeds with conventional activated sludge cultivated at different solid retention times (SRTs) are compared. A clear influence of the SRT of the inoculum was observed, corresponding to an SRT of 10 days to the higher current density exerted, about 0.2 A m −2 . This observation points out that, in this type of electrochemical device, it is recommended to use high SRT seeds. The work also points out that in order to promote an efficient start-up, it is not only necessary to use high SRT seeds, but also to feed a high COD concentration. When feeding 10,000 ppm COD and keeping SRT of 10 d differences of current densi…

Il tarantismo in Sicilia

2017

Il testo prende in esame il complesso di materiali editi e inediti (fonti storiche e archivistiche, documenti musicali, testimonianze etnografiche) che attestano la presenza del tarantismo in Sicilia dalla metà del Seicento alla fine dell’Ottocento. Il caso siciliano viene quindi inquadrato nell’ambito dell’ampia letteratura che ruota intorno al fenomeno, a partire dal classico studio di Ernesto De Martino fino al dibattito sull’interpretazione del fenomeno fra i poli dell’esorcismo e della possessione, dovuto soprattutto all’etnomusicologo francese Gilber Rouget. L’analisi viene quindi estesa alla tradizione dei guaritori dei morsi di serpenti (i ciaràuli), che con il tarantismo condividon…

Settore L-ART/08 - EtnomusicologiaThe text examines published and unpublished materials – such as historical and ethnographic sources archive records and musical documents – which testify the presence of tarantism in Sicily from mid-17th century to the end of the 19th. The Sicilian case is then considered in a wider context of contributions on the theme starting from the ‘classic’ De Martino’work up to the debate on the interpretation of the phenomenon between the poles of exorcism and possession chiefly rased by French ethnomusicologist Gilbert Rouget. The analyses is therefore expanded to the tradition of snakes bites healers (the ciaràuli) which shares with tarantism the spider symbolism and to certain kinds of religious processions characterised by frantic ‘dances’ which suggest elements of functional continuity with tarantism musical-choreutic therapy.
