Optimizing the physical parametrizations of the Weather Research and Forecasting (WRF) model is one of the most challenging and complex tasks. In fact, it is not a simple operation to optimize the performance of a meteorological model capable of forecasting meteorological events, even extreme ones, in complex orographic areas such as that of Sicily. In this reference framework, the research activity of the group of meteorology and environmental modeling, established at the Department of Mathematics and Computer Sciences, Physical Sciences and Earth Sciences (MIFT) of the University of Messina, focuses on the development of a physical-mathematical model for the meteorological forecast. The WRF prediction model is evaluated on the ability to predict the development and evolution of a thunderstorm cell. After the definition of the domain under study and the choice of spatial resolution to be used, it was proceeded to the optimization of the physical parametrizations. In particular, in this paper, the performance improvements of the WRF model were evaluated, obtained by optimizing the convective parametrizations. As a case study, the meteorological event recorded in Sicily on 9 June 2016 was examined.

Col seguente contributo si propone una riflessione sull’approccio socio-culturale allo studio dei disastri partendo da due casi, i quali, come verrà dimostrato, pur nella loro peculiarità presentano similitudini incontrovertibili. Si tratta dell’analisi di due eventi sismici che hanno gravemente colpito il territorio italiano. Il primo ha interessato l’Abruzzo e la città de L’Aquila il 6 aprile 2009; il secondo ha coinvolto la porzione nord-orientale della pianura padano-emiliana con una serie di scosse tra il 20 e il 29 maggio 2012. Presentando i risultati delle due ricerche – la prima condotta dalla primavera all’autunno del 2014, la seconda tra ottobre 2012 e novembre 2014 - l’obiettivo è di operare un’approfondita analisi comparativa delle varie fasi della gestione dell’emergenza post-sismica e della successiva ricostruzione. Verranno considerate le strategie messe in campo dagli attori collettivi (movimenti, associazioni, comitati) per riappropriarsi degli spazi perduti, ricostruendo dal basso le reti di solidarietà. Si descriveranno i fattori di vulnerabilità che hanno contribuito a circoscrivere temporalmente e a rendere residuali gran parte di queste iniziative. Le due esperienze etnografiche si inquadrano all’interno del quadro teorico socio-antropologico sui disastri, con il fondamentale apporto della Sociologia e dell’Antropologia nella comprensione delle dinamiche di costruzione del senso, dei rapporti di potere-sapere, dell’organizzazione istituzionale, dei modelli di gestione dell’emergenza, degli strumenti messi in campo per “governare” il mutamento determinato dall’impatto di un agente distruttivo (terremoto) sulle comunità umane. Tramite, dunque, un doppio dialogo - tra le due ricerche e tra le due discipline - si dimostreranno due principi fondamentali: il primo attiene all’urgenza di continuare a operare ricerche in una tensione comparativa su questa tipologia di eventi, soprattutto in Italia; il secondo riguarda l’importanza di farlo in una prospettiva che metta in collaborazione disciplinare diverse. Anche l’intento appare duplice: da un lato quello di individuare concetti, principi, azioni e comportamenti simili che possano poi contribuire alla costruzione di un sapere riguardo a come dare senso all’esperienza disastrosa, a come porvi rimedio in maniera efficace per chi l’ha vissuta; dall’altra una tale prospettiva può stimolare elaborazioni teoriche alternative rispetto a quelle tradizionali e in tal senso innovative, in grado di collocare il disastro all’interno di un contesto molto più ampio, che comprenda le politiche pubbliche, le diverse percezioni dell’evento e l’evoluzione della storia che esso inevitabilmente determina.

In the context of the census of sixteenth and seventeenth century tragedies, we publish the record of Trissino’s Sofonisba, the first Italian regular tragedy. ------ Nel contesto del censimento delle tragedie cinque-seicentesche si pubblica la scheda sulla Sofonisba del Trissino, la prima tragedia regolare italiana.

The development of numerical models for meteorological analysis is often based on nonlinear equations systems describing complex fluids, having more components and for which generalized Navier-Stokes equations are used. In several real cases it is necessary to use numerical calculation approaches in which the equations are discretized. The aim of this contribution is working out results regarding the optimization of the performance of a mathematical-physical model, formulated for meteorology forecasts in limited and high resolution area, and obtained by interdisciplinary studies. In particular, in order to test the validity of the presented model, different microphysical parameterizations have been analyzed, every one taking into account different hydrometeor nucleation processes.

We present the guidelines for a census of published and unpublished sixteenth and seventeenth century tragedies, with the aim of creating a constantly updated database, designed as a working tool for scholars and historians of literature and theatre. Si presentano le linee programmatiche di un censimento delle tragedie cinque-seicentesche, edite e inedite, con l’obiettivo di realizzare una banca dati continuamente aggiornata, progettata come strumento di lavoro per gli studiosi e gli storici della letteratura e del teatro.

This paper, starting from the awareness of the anthropological finitude, aims to investigate the symbolic meaning of the catastrophe in today's society. With reference to E. De Martino’s and G. Anders’s anthropo - philosophical theses, the paper analyzes the representation of present catastrophes as Apocalypses without eskaton, in which the "blindness" of man and his inability to react is manifested. Both technological catastrophes directly caused by man and environmental disasters indirectly produced by anthropic neglect causes a widespread sense of powerlessness, leaving man devoid of theoretical and practical means to guide his action. This implies, however, the necessity to widen human "feel" and the ability to understand the "meaning" of our actions in the world. This paper aims to examine all these issues through an ecocritic analysis of the novel The Road by C. McCarthy, in order to show that there is still a deeply human way to experience the fragility and to represent the catastrophe.

Protection of copyright of the digital images is a critical element for the multimedia Web applications, e-books, virtual picture gallery. This problem is today receiving growing attention due to the pervasive diffusion of Internet technology. This work shows the watermark as solution to this problem and describes a new wavelet-based algorithm, called WM1.0, which is invisible, private, strong. WM1.0 watermaks a subset of digital images building the ecclesiastic on-line art collection. The Owner of the images and related information is the Italian Episcopal Conference, whereas the Publisher is I.D.S., an ICT company located in Messina.

Following the fall of the empire and the establishment of the Republic of China (1912), the Chinese borders suddenly opened up to more intensive and profitable exchanges with the outside world. As a result, an increasing number of Chinese were able to travel to Europe, and Chinese travel literature production about Europe boomed in the 1920s and 1930s. One of these travellers was Zou Taofen (1895-1944), a journalist forced to leave China in 1933. He authored a three-volume book entitled Messages from an Unending Wandering. Zou was one of the most famous journalists of his era. In his overseas “Messages”, he was able to detect the conflicts and contradictions lurking behind the prosperity of Europe, to reveal the dark side of the society at the time and the exploitation caused by capitalism.

The aim of this paper is to verify the applicability of the Rayleigh-Lamb equation to drops having different diameters and, specifically, with diameters of the order of magnitude of centimeters (macro drops), millimeters or micrometers (micro drops). On this purpose three experiments have been taken into account. A completely new fact is constituted by the following question: it is possible to apply the Rayleigh-Lamb equation to a heterogeneous drop like that represented by a soap bubble, characterized by a surface tension different from the substance constituting the drop's mass (air)? The results reported in this paper seem to confirm that this is possible. The order of magnitude of the calculated autofrequencies is comparable to that observed experimentally. The limitations of the experiments are the geometry of the system. The Rayleigh-Lamb equation applies, strictly speaking, to a free drop not subjected to the action of external forces. This would be possible through the use of special devices, i.e. the Acoustical Levitated. Therefore, it was decided to carry out the experiments with drops bound by viscous adhesion to the respective supports. It is evident that the geometry of the drop is no longer perfectly spherical, however the results obtained do not seem to have suffered greatly from this limitation.

We propose a didactic approach to use the Machine Learning protocol in order to perform weather forecast. This study is motivated by the possibility to apply this method to predict weather conditions in proximity of the Etna and Stromboli volcanic areas, located in Sicily (south Italy). Here the complex orography may significantly influence the weather conditions due to Stau and Foehn effects, with possible impact on the air traffic of the nearby Catania and Reggio Calabria airports. We first introduce a simple thermodynamic approach, suited to provide information on temperature and pressure when the Stau and Foehn effects take place. Then, in order to gain information also on the rainfall accumulation, the Machine Learning approach is presented: according to this protocol, the model is able to "learn'' from a set of input data constituted by the meteorological conditions (in our case dry, light rain, moderate rain and heavy rain) associated to the rainfall, measured in mm. We observe that, since in the input dataset provided by the Salina weather station the dry condition was the most common, the algorithm is very accurate in predicting it. Further improvements can be obtained by increasing the number of considered weather stations and the time interval.

A didactic multiscale approach for drone modeling is proposed. Specifically, we investigate the drone structure at both macroscopic and microscopic scales, by making use of finite element and atomistic simulations, respectively. The structural analysis is performed with the aim to equip the drone with specific sensors and measuring instruments capable to detect the existence of volcanic ash, SO_2, CO_2 and other pollutants in the atmosphere after a vulcanic eruption. We show that, by modeling the tubular structure of the drone with a sandwich constituted by a a polystyrene core, carbon fiber skins and epoxy matrix, a weight saving of 7 grams for each drone arm can be obtained, in comparison to the standard commercial drones, although a slight worsening of the mechanical performances is observed. In addition, the molecular structure of the polystyrene chains has been investigated by using atomistic Molecular Dynamics simulations, providing further information on the local structure of the polymer chains. Additional improvements of the weight saving could be obtained by means of the the topological optimization techniques on the body of the drone and on the supports for landing.

The main objective of this article is to briefly illustrate the contribution of Italian sinology in compiling dictionaries of the Chinese language. Michele Ruggieri and Matteo Ricci succeed in compiling a list of words by means of a new transcription method which will be later improved and adopted by many Europeans. Basilio Brollo compiled a dictionary which was very popular in 18th century Europe and was the first Chinese one ever published. Two other missionaries worked for years on a dictionary: Carlo Castorano and Joseph Pruggmayr. Their works can be considered the earliest Italian-Chinese dictionaries but they haven’t been studied in detail so far. The last section, dealing with the 19th century, list in brief, all the failed attempts to print a bilingual dictionary in Italy.

Il contributo porta alla luce alcune testimonianze, a oggi inedite, del lavorio di Giovanni Pascoli intorno a un sonetto sul giorno natale di Roma, L’aratro è fermo: il toro, d’arar sazio, e alla sua traduzione in esametri latini, XI Kal. Maias (Poematia et epigrammata, IX). I materiali autografi, di cui si fornisce il testo critico e un primo inquadramento storico-culturale, ci consentono di entrare all’interno del laboratorio bilingue del poeta, aprendo nuove prospettive di ricerca nel panorama della produzione pascoliana dei primi anni Novanta. The paper brings to light some evidence, to date unpublished, of Giovanni Pascoli’s work on a sonnet on the birthday of Rome, L’aratro è fermo: il toro, d’arar sazio, and on his translation into latin hexameters, XI Kal. Maias (Poematia et epigrammata, IX). The autograph materials, of which we provide the critical text and a first historical and cultural framework, allows us to open new research prospects in Pascoli’s production of the early Nineties.

L'iperossaluria primaria di tipo 1 è causata da mutazioni nel gene codificante per l'enzima L-alanina-gliossilato amino transferasi (AGT), che è espresso nel fegato. La trasmissione avviene con modalità autosomica recessiva: i genitori sono portatori sani della mutazione (e spesso non sanno di averla, soprattutto se non ci sono familiari affetti), mentre ciascun figlio della coppia ha il 25% di probabilità di essere malato. Esiste anche un secondo tipo della malattia (iperossaluria primaria di tipo 2), causato dalla carenza di un altro enzima, la D-glicerato deidrogenasi, e un terzo tipo (iperossaluria di tipo 3), identificato piú di recente e causato dal difetto del gene DHDPSL. Sulla base dell'osservazione clinica ed eventualmente della storia familiare, la diagnosi di iperossaluria primaria può essere formulata grazie a test di laboratorio (misurazione dell'ossalato di calcio nelle urine e nel sangue) e analisi genetica, con ricerca delle mutazioni nel gene coinvolto. La diagnosi e il trattamento precoci sono in grado di ridurre il rischio di evoluzione verso l'IRC e verso complicanze gravi come l'ossalosi sistemica. L'articolo riguarda un caso clinico che ha coinvolto il gruppo infermieristico che ha modificato l'approccio e la presa in carico di un adolescente in un “mondo” di adulti. (sian) (nursing)
