Séisme 2016 et Amatrice: au-delà des représentations sensationnalistes, la recherche-action militante
2021
Dopo il terremoto del 2016-2017, l'Appennino centrale italiano sta attraversando una lunga fase di transizione tra l'urbicidio e la ricostruzione. La riflessione emerge da una ricerca sui processi di ri-territorializzazione della città di Amatrice, nel cuore del cratere del terremoto: un lavoro all'incrocio tra la geografia sociale e culturale, sostenuto da nove mesi di lavoro sul campo. Dopo aver descritto il sistema di gestione dell'emergenza, ci si interroga sulla dimensione di rappresentazione del disastro. Criticando l'iconografia sensazionalista, si descrive l'esperienza di ricerca di Emidio di Treviri, un collettivo di ricerca-azione nato per documentare e analizzare i processi socio…
DETERMINATION OF ABUSED SUBSTANCES IN BIOLOGICAL MATRICES FOR TOXICOLOGICAL AND FORENSIC PURPOSES
2019
During the year 2017, a research work was carried out at the Department of laboratory diagnostics - Toxicology and Biochemistry U.O.S. of ASP 6 in Palermo. The purpose of this investigation was to perform a second level analysis in order to look for abuse drugs. The sample used consisted of 73 serum tubes, which had previously tested positive for screen- ing tests. The result of the analysis of these samples revealed a false positivity in most cases. From the information gathered through the sampling reports, it appears that the age group with several drivers, who are subject to checks by the traffic police, is the one from 17 to 30 years, with 35 samples analysed (48%). It also emerged tha…
Higher order matrix differential equations with singular coefficient matrices
2014
In this article, the class of higher order linear matrix differential equations with constant coefficient matrices and stochastic process terms is studied. The coefficient of the highest order is considered to be singular; thus, rendering the response determination of such systems in a straightforward manner a difficult task. In this regard, the notion of the generalized inverse of a singular matrix is used for determining response statistics. Further, an application relevant to engineering dynamics problems is included.

Jacobi Fields, Conjugate Points
2001
Let us go back to the action principle as realized by Jacobi, i.e., time is eliminated, so we are dealing with the space trajectory of a particle. In particular, we want to investigate the conditions under which a path is a minimum of the action and those under which it is merely an extremum. For illustrative purposes we consider a particle in two-dimensional real space.
Il Tesoro della Matrice Nuova di Castelbuono nella Contea dei Ventimiglia
2005
Il prezioso e in gran parte inedito corpus di suppellettili argentee della Chiesa Madre di Castelbuono, legato alla committenza della famiglia Ventimiglia analiticamente indagata, viene schedato secondo la più attuale metodologia catalografica e storico critica. La monografia è compendiata da un catalogo dove ciascun manufatto è descritto e contestualizzato nella temperie stilistica di riferimento, evidenziando le influenze artistiche nazionali ed internazionali. La rassegna di opere d’arte proposte nel volume copre un arco cronologico che va dal 1338 al XIX secolo. Vengono inoltre suggerite linee guida per una eventuale musealizzazione

Flexible and Efficient Computer-Aided Design Tool for Advanced Comb-Line Rectangular Waveguide Filters
2015
A very flexible and efficient computer-aided design (CAD) tool, specifically suited for advanced comb-line rectangular waveguide filters, is presented in this work. The developed software tool, which makes use of a full-wave analysis technique based on the Boundary Integral - Resonant Mode Expansion method, permits to load the considered comb-line resonators with any number of radially symmetrical partial-height metallic posts. The implemented CAD tool also allows for dealing with coupling windows of arbitrary cross-section, thus drastically enhancing the flexibility of the computer-aided design process. The excitation of the analyzed components, which is performed by using generalized coax…
