Analysis of Illumina BovineSNP50 BeadChip data in different Italian cattle breeds to identify useful markers for breed authentication of dairy and be…

2013

The identification of the breed of origin of cattle derived products has recently assumed particular relevance since the increasing interest in marketing mono-breed labelled cheese and beef. These products are usually sold at a higher price creating financial incentives to substituting them with lower value products coming from undifferentiated or common breeds or crossbred animals. Frauds can damage these valuable niche markets that, indirectly, may help to preserve genetic diversity through the economic incentive on raising local breeds, derived by the high value products, that are usually less productive. DNA analysis can help to identify fraudulent behaviour as we already demonstrated f…

Aphyllophoraceous wood-inhabiting fungi on Fagus sylvatica in Italy

2007

166 species representing 84 genera of aphyllophoraceous fungi growing on Fagus sylvatica in Italy are listed. Steccherinum robustius is reported as new to Italy, while many species are considered rare in Italy, e.g. Antrodiella ichnusana, Crustomyces subabruptus and Dentipellis fragilis.

Analysis of lipids in pelagic fish of Sicilian Channel and use of fatty acids as bacterial contamination markers

Lipids provide the expendable form of energy in marine ecosystem, and have an important role for the reproductive biology of fish. Also, lipids are important nutrients, versatile markers for marine trophic studies, bacteria markers etc. Among the lipids, several essential fatty acids are determinants for ecosystem health as well as for their known nutritional properties and prevention capacity of chronic diseases. Furan fatty acids (F - acids) are other important lipid bioactive compounds; for these is hypothesized a crucial nutritional role that is synergistic to polyunsaturated fatty acids omega 3 (PUFA ω 3), also if their mechanism is not yet clear. Source of essential fatty acid is the …

Giuseppe Samonà e la “spina dorsale” di Gibellina Nuova

2020

Nel 1970 Giuseppe Samonà coordina il gruppo di progettazione formato da Vittorio Gregotti, Gianni Pirrone e Alberto Samonà per il Progetto del Centro civico, commerciale e culturale di Gibellina Nuova. Del piano è realizzato il municipio e poi, rielaborato e in altro luogo, il teatro. I monumenti, fondati su un asse pedonale in quota connesso a un suolo artificiale articolato, esprimono l’unità architettura – urbanistica e anticipano, per certi versi, una riflessione successiva del Direttore dello IUAV sulla dialettica fra urbano e rurale.

Settore ICAR/14 - Composizione Architettonica E UrbanaIn 1970 Giuseppe Samonà coordinated a design team (with Vittorio Gregotti Gianni Pirrone and Alberto Samonà) for the project of the Civic Commercial and Cultural Centre of Gibellina Nuova. From this plan among the monuments just the town hall was built. The theatre was proposed later for a different place. The buildings should have been linked to a pedestrian axial gangway connected to an articulated artificial ground. The complex should have shown the unity between architecture and urban planning anticipating in some ways a later Samona’s reflection about the dialectic between urban and rural.

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.

STUDIO DI UN AMMORTIZZATORE ELETTROMAGNETICO A RECUPERO DI ENERGIA

2013

Questo lavoro ha come obiettivo principale lo studio teorico e con supporto di software F.E.M. di un dispositivo che consenta recupero energetico da una sospensione automobilistica. In sostituzione allo smorzatore viscoso, che dissipa l’energia cinetica del veicolo a seguito dell’attraversamento di strade sconnesse o ostacoli più marcati, si è usato uno smorzatore elettromagnetico che svolga le funzioni dello smorzatore viscoso consentendo un recupero di energia elettrica. Lo smorzatore elettromagnetico è di tipo a magneti permanenti e il suo funzionamento si basa sul fenomeno dell’induzione elettromagnetica. Il modello matematico descrive il funzionamento dello smorzatore, restituendo i va…

Settore ING-IND/14 - Progettazione Meccanica E Costruzione Di MacchineMain objective of this work is the theoretical study and support of FEM software of a device that allows for energy recovery from an automotive suspension. In replacing the viscous damper which dissipates the kinetic energy of the vehicle due to rough roads or obstacles more marked an electromagnetic damper is used that performs the functions of the viscous damper allowing a recovery of electricity. The damper is of the electromagnetic type with permanent magnets and its operation is based on the phenomenon of electromagnetic induction. The mathematical model describes the operation of the damper restoring the values of the electrical and mechanical magnitudes as a function of the relative speed between the rod and the stator. Energy recovery has been estimated considering an electric minicar that transits on a bumpy road. The recovered power has a total value of about 250W.

An Embedded System for the integration of a Combined Photovoltaic Solar (CPS) system into a ZigBee Home Area Network

2011

In this paper is reported the design and implementation of an electronic system capable of communicating over a standard ZigBee network in order to let a residential gateway collector, named agent, gain access to the parameters of a Combined Photovoltaic and Solar thermal (CPS) plant, thus realizing a networked energy production appliance . The system is made of three parts: a PV metering device, a boiler metering device also capable of controlling a heating resistor embedded within the boiler tank, and a data collector acting as a ZigBee node. The data collector device periodically retrieves the following parameters from the metering devices: instantaneous photovoltaic power production, ac…

Cross-Technology WiFi/ZigBee Communications: Dealing With Channel Insertions and Deletions

2016

In this letter, we show how cross-technology interference can be exploited to set up a low-rate bidirectional communication channel between heterogeneous WiFi and ZigBee networks. Because of the environment noise and receivers' implementation, the cross-technology channel can be severely affected by insertions and deletions of symbols, whose effects need to be taken into account by the coding scheme and communication protocol.
