Due genitori, quattro figli, e un nipote che a distanza di anni decide di ripercorrere e raccontarci le loro storie.Una madre che vive tormentata dal suo spettro e che decide di abbandonare la propria famiglia e i propri figli per seguire un altro uomo. Un padre che tiene con violenza le redini delle proprie relazioni, e che rifiuta l’occidente in tutte le sue forme per restare aggrappato alle proprie tradizioni. Un figlio che sceglie l’ordine e la carriera militare, e che, incapace di risolvere il suo rapporto di dipendenza dalla madre, e di risolvere il conflitto tra la legge e un affetto quasi morboso, sceglie di suicidarsi. Un figlio che sceglie la via della perdizione, delle droghe, del furto e degli affari illegali, e che va incontro al successo e alla ricchezza... CAPITOLO TERZO. Biografia di Sa’d Allah Wannus, presentazione delle sue opere principali. Sa’d Allah Wannus (1941 – 1997) è sicuramente uno dei principali protagonisti nell’ambito del teatro arabo contemporaneo. Scrittore, critico, drammaturgo, riformatore, uomo impegnato politicamente, e infine essere umano nella lotta tra la vita e la morte (muore a 56 anni per tumore, dopo un lungo periodo di degenza). Mio intento è quello di analizzare l’opera di quest’autore, attraverso i suoi numerosi scritti e piece teatrali (purtroppo al giorno d’oggi ancora quasi interamente non tradotte dall’arabo), fino ad arrivare, attraverso queste, ad una lettura della società araba contemporanea, e al ruolo che il teatro assume al suo interno. Vita e opere di Sa’ad Allah Wannus. Nasce in Siria nel 1941 in un piccolo villaggio vicino alla città di Tartous, sulla costa mediterranea. Dopo aver terminato gli studi superiori, nel 1959, parte per Il Cairo (Egitto), per studiare giornalismo e letteratura. Rientra a Damasco nel 1964, lavorando al tempo stesso come funzionario al ministero della cultura e come redattore o giornalista in alcune riviste e quotidiani siriani. Nel 1966 parte per Parigi, dove studierà con Jean-Louis Barrault, e dove farà la conoscenza delle tendenze del teatro contemporaneo. Ha l’occasione di incontrare scrittori e critici importanti come Jean Genet e Bernard Dort, nonché di conoscere le teorie sul teatro di Brech e di Piscator, dai quali sarà chiaramente influenzato. In questi anni, e soprattutto in seguito agli avvenimenti del Maggio 1968, si sviluppa in modo determinante la sua coscienza politica, e sono questi gli anni in cui compone alcune tra le sue piece più importanti, come: Serata di gala per il 5 giugno (haflat samar min ajl khamsa huzayran) nel 1968, L’elefante, oh re del tempo! (al-fil, ya malik al-zaman!) 1969, Le avventure della testa del Mamelucco Jaber (Meghamarat ra’s al-mamluk Jabiir) 1970, Una serata con Abu-Khalil al- Qabbani (Sahra ma’a Abi Khalil Al-Qabbani) 1972, Il re è il re (al-malik uwa al-malik) 1977. Parallelamente porta avanti una intensa attività artistica e intellettuale. Soggiorna di nuovo in Francia e a Weimar, per portare a termine la sua formazione teatrale, fonda il Festival di teatro di Damasco, traduce e mette in scena numerosi spettacoli, scrive e pubblica numerosi articoli e una importante serie di studi sul teatro, intitolata: Manifesto per un nuovo teatro arabo (bayanat limasrah ‘arabi jadid) (1970). Scrive in numerose riviste e giornali e fonda la rivista La vita teatrale (al-hayyat al-masrahiyya), del quale sarà capo redattore. La visita del presidente egiziano Anouar Sadat a Gerusalemme nel 1977 e gli accordi di Camp David l’anno seguente, lo gettano in una profonda depressione. E’ l’inizio di un lungo periodo di silenzio e di smarrimento. Ritornerà a scrivere solamente nel 1989, con l’inizio della prima Intifada palestinese, scrive allora una piece teatrale intitolata Lo stupro (al-ightisab), dove presenta un’analisi della struttura dell’elite al potere in Israele. Questo testo apre una nuova epoca creativa, durante la quale Wannus compone alcuni testi molto importanti, nonostante la malattia e il cancro che gli viene diagnosticato nel 1992. Tra questi le pieces Miniature storiche (munamnamat tarakhiyya), nel 1993, e Rituali per una metamorfosi (tukus al-isharat wa-l-tahawwulat), nel 1994 e A proposito della memoria e della morte (‘an al-dhakira wa-l-mawt) nel 1996, una sua ultima opera in cui sono raccolti dei racconti, drammi brevi e una lunga meditazione sulla malattia e la morte. Nel 1997 l’UNESCO gli chiede di redigere il messaggio per la Giornata Mondiale del Teatro, che si tiene ogni anno il 27 marzo. Nel 1997, poche settimane prima della sua scomparsa, realizza insieme ad Omar Almiralay il film documentario Il y a tant de choses a reconter, una intervista in cui Wannus parla della sua opera, e del conflitto Israelo-Palestinese. Muore a 56 anni, il 15 maggio 1997, per un’amara coincidenza proprio il giorno anniversario della creazione di Israele. Wannus drammaturgo engagè: l’importanza del conflitto israelo palestinese nella sua opera. Un’analisi dell’influenza e dell’importanza che le opere di Wannus hanno avuto nel seno della società araba, e soprattutto il suo impegno costante nell’uso del teatro come mezzo per la presa di coscienza del pubblico dei problemi della società contemporanea. Punto cardine dell’opera di Wannus, il conflitto israelo palestinese, e il tentativo costante in alcune sue opere di analizzarne le cause, le strutture, le parti, i giochi di potere. E’ il simbolo di tutta la generazione di Wannus, e delle successive. Analisi delle illusioni e dei miti che la società araba ripropone e che Wannus ha cercato più volte di mettere a nudo. La lotta contro le ipocrisie dei governi, e il tentativo di far prendere coscienza alla società araba del suo ruolo, e delle conseguenze delle sue azioni. L’individuo, la famiglia, la società ... il teatro. Distruggere le apparenze per mettere a nudo l’essere umano nella sua fragilità. CONCLUSIONI. APPENDICE: Intervista con Marie Elias BIBLIOGRAFIA.

Sviluppo e validazione di un modello di film fluido per simulazioni CFD di motori a combustione interna

A wall film model has been implemented in a customized version of KIVA code developed at University of Bologna. Under the hypothesis of `thin laminar ow' the model simulates the dynamics of a liquid wall film generated by impinging sprays. Particular care has been taken in numerical implementation of the model. The major phenomena taken into account in the present model are: wall film formation by impinging spray; body forces, such as gravity or acceleration of the wall; shear stress at the interface with the gas and no slip condition on the wall; momentum contribution and dynamic pressure generated by the tangential and normal component of the impinging drops; film evaporation by heat exchange with wall and surrounding gas. The model doesn't consider the effect of the wavy film motion and suppose that all the impinging droplets adhere to the film. The governing equations have been integrated in space by using a finite volume approach with a first order upwind differencing scheme and they have been integrated in time with a fully explicit method. The model is validated using two different test cases reproducing PFI gasoline and DI Diesel engine wall film conditions.

Testo e memoria tra semiotica e scienze cognitive: una situazione sperimentale intorno al ricordo di un film

The research project presented in this dissertation is about text and memory. The title of the work is "Text and memory between Semiotics and Cognitive Science: an experimental setting about remembering a movie". The object of the research is the relationship between texts or "textuality" - using a more general semiotic term - and memory. The goal is to analyze the link between those semiotic artifacts that a culture defines as autonomous meaningful objects - namely texts - and the cognitive performance of memory that allows to remember them. An active dialogue between Semiotics and Cognitive Science is the theoretical paradigm in which this research is set, the major intend is to establish a productive alignment between the "theory of text" developed in Semiotics and the "theory of memory" outlined in Cognitive Science. In particular the research is an attempt to study how human subjects remember and/or misremember a film, as a specific case study; in semiotics, films are “cinematographic texts”. The research is based on the production of a corpus of data gained through the qualitative method of interviewing. After an initial screening of a fulllength feature film each participant of the experiment has been interviewed twice, according to a pre-established set of questions. The first interview immediately after the screening: the subsequent, follow-up interview three months from screening. The purpose of this design is to elicit two types of recall from the participants. In order to conduce a comparative inquiry, three films have been used in the experimental setting. Each film has been watched by thirteen subjects, that have been interviewed twice. The corpus of data is then made by seventy-eight interviews. The present dissertation displays the results of the investigation of these interviews. It is divided into six main parts. Chapter one presents a theoretical framework about the two main issues: memory and text. The issue of the memory is introduced through many recherches drown up in the field of Cognitive Science and Neuroscience. It is developed, at the same time, a possible relationship with a semiotic approach. The theoretical debate about textuality, characterizing the field of Semiotics, is examined in the same chapter. Chapter two deals with methodology, showing the process of definition of the whole method used for production of the corpus of data. The interview is explored in detail: how it is born, what are the expected results, what are the main underlying hypothesis. In Chapter three the investigation of the answers given by the spectators starts. It is examined the phenomenon of the outstanding details of the process of remembering, trying to define them in a semiotic way. Moreover there is an investigation of the most remembered scenes in the movie. Chapter four considers how the spectators deal with the whole narrative. At the same time it is examined what they think about the global meaning of the film. Chapter five is about affects. It tries to define the role of emotions in the process of comprehension and remembering. Chapter six presents a study of how the spectators account for a single scene of the movie. The complete work offers a broad perspective about the semiotic issue of textuality, using both a semiotic competence and a cognitive one. At the same time it presents a new outlook on the issue of memory, opening several direction of research.

Atomistic simulations of bulk and free standing film smectics

In questa tesi viene descritto lo studio delle fasi liquido-cristalline del 4-n-ottil-4-cianobifenile eseguito tramite simulazioni al calcolatore molecular dynamics, sia per campioni bulk che per film smectici sottili. Impiegando un campo di forze "molecular mechanics" precedentemente usato con successo per studiare sistemi composti da 250 molecole della serie degli n-cianobifenili (nCB, con n pari a 4-8 atomi di carbonio nella catena alifatica), si è simulato il comportamento di un sistema bulk di 750 molecole e di un film smectico di 1500 molecole. Nel primo caso, sottoponendo il campione a un graduale raffreddamento, si è osservata la formazione spontanea di fasi ordinate quali quella nematica e quella smectica. Nel secondo caso, invece, si è studiata l'influenza dell'interfaccia con il vuoto sull'ordine posizionale e orientazionale di film sottili di diverso spessore e temperatura. Si sono confrontate le proprietà di entrambi i sistemi simulati con i dati sperimentali disponibili in letteratura, confermando la bontà del modello nel riprodurre fedelmente le caratteristiche dei campioni reali.

In situ real-time investigation of Organic Ultra-Thin-Film transistors: growth, electrical properties and biosensing applications

Organic electronics has grown enormously during the last decades driven by the encouraging results and the potentiality of these materials for allowing innovative applications, such as flexible-large-area displays, low-cost printable circuits, plastic solar cells and lab-on-a-chip devices. Moreover, their possible field of applications reaches from medicine, biotechnology, process control and environmental monitoring to defense and security requirements. However, a large number of questions regarding the mechanism of device operation remain unanswered. Along the most significant is the charge carrier transport in organic semiconductors, which is not yet well understood. Other example is the correlation between the morphology and the electrical response. Even if it is recognized that growth mode plays a crucial role into the performance of devices, it has not been exhaustively investigated. The main goal of this thesis was the finding of a correlation between growth modes, electrical properties and morphology in organic thin-film transistors (OTFTs). In order to study the thickness dependence of electrical performance in organic ultra-thin-film transistors, we have designed and developed a home-built experimental setup for performing real-time electrical monitoring and post-growth in situ electrical characterization techniques. We have grown pentacene TFTs under high vacuum conditions, varying systematically the deposition rate at a fixed room temperature. The drain source current IDS and the gate source current IGS were monitored in real-time; while a complete post-growth in situ electrical characterization was carried out. At the end, an ex situ morphological investigation was performed by using the atomic force microscope (AFM). In this work, we present the correlation for pentacene TFTs between growth conditions, Debye length and morphology (through the correlation length parameter). We have demonstrated that there is a layered charge carriers distribution, which is strongly dependent of the growth mode (i.e. rate deposition for a fixed temperature), leading to a variation of the conduction channel from 2 to 7 monolayers (MLs). We conciliate earlier reported results that were apparently contradictory. Our results made evident the necessity of reconsidering the concept of Debye length in a layered low-dimensional device. Additionally, we introduce by the first time a breakthrough technique. This technique makes evident the percolation of the first MLs on pentacene TFTs by monitoring the IGS in real-time, correlating morphological phenomena with the device electrical response. The present thesis is organized in the following five chapters. Chapter 1 makes an introduction to the organic electronics, illustrating the operation principle of TFTs. Chapter 2 presents the organic growth from theoretical and experimental points of view. The second part of this chapter presents the electrical characterization of OTFTs and the typical performance of pentacene devices is shown. In addition, we introduce a correcting technique for the reconstruction of measurements hampered by leakage current. In chapter 3, we describe in details the design and operation of our innovative home-built experimental setup for performing real-time and in situ electrical measurements. Some preliminary results and the breakthrough technique for correlating morphological and electrical changes are presented. Chapter 4 meets the most important results obtained in real-time and in situ conditions, which correlate growth conditions, electrical properties and morphology of pentacene TFTs. In chapter 5 we describe applicative experiments where the electrical performance of pentacene TFTs has been investigated in ambient conditions, in contact to water or aqueous solutions and, finally, in the detection of DNA concentration as label-free sensor, within the biosensing framework.

Außerirdische im amerikanischen Sciencefiction-Film

Die vorliegende Dissertation untersucht die Darstellung von außerirdischen Lebensformen im amerikanischen Sciencefiction-Film in Form eines filmhistorischen Gesamtüberblicks.Noch bevor der 1. Weltkrieg begann, waren die meisten Genremerkmale, die den Sciencefiction-Film bis heute charakterisieren, bereits erdacht. Die wenigen Sciencefiction-Filme, die Außerirdische zeigten, fügten sich jedoch sehr gut in den verspielten, märchenhaften Sciencefiction-Film der Vorkriegszeit. Bis sich das Topos des Außerirdischen als eigenes Subgenre etablieren konnte, sollten aber noch einige Jahrzehnte vergehen. Im Jahr 1950 nahm das Interesse am Weltraum schlagartig zu. Bei der Darstellung der fremden Wesen orientierte man sich zunächst an irdischen Vorbildern und es entstanden zahlreiche humanoide, tierische, pflanzliche, mineralische und amorphe außerirdische Lebensformen, die dem Menschen oft überlegen waren. In den 60ern brach der Mensch häufiger selbst in den Weltraum auf - immer öfter standen Menschen und Außerirdische nun auf gleicher Stufe. In den 70ern wurden die märchencharakteristischen Begriffe Gut und Böse durch Außerirdische verkörpert. In den 80ern gelang es dem Guten, sich durchzusetzen. Einige wunderbare Freundschaften zwischen Menschen und Außerirdischen entwickelten sich und Außerirdische wurden in die menschliche Gesellschaft integriert. Damit scheinen aber alle Spielarten des Guten gezeigt zu sein und in den 90ern ist wieder Raum für Geschichten, in denen Außerirdische das Böse verkörpern.

Percorsi di gender performance: fotografia tra arte e moda dagli anni Novanta ad oggi

My project explores and compares different forms of gender performance in contemporary art and visual culture according to a perspective centered on photography. Thanks to its attesting power this medium can work as a ready-made. In fact during the 20th century it played a key role in the cultural emancipation of the body which (using a Michel Foucault’s expression) has now become «the zero point of the world». Through performance the body proves to be a living material of expression and communication while photography ensures the recording of any ephemeral event that happens in time and space. My questioning approach considers the gender constructed imagery from the 1990s to the present in order to investigate how photography’s strong aura of realism promotes and allows fantasies of transformation. The contemporary fascination with gender (especially for art and fashion) represents a crucial issue in the global context of postmodernity and is manifested in a variety of visual media, from photography to video and film. Moreover the internet along with its digital transmission of images has deeply affected our world (from culture to everyday life) leading to a postmodern preference for performativity over the more traditional and linear forms of narrativity. As a consequence individual borders get redefined by the skin itself which (dissected through instant vision) turns into a ductile material of mutation and hybridation in the service of identity. My critical assumptions are taken from the most relevant changes occurred in philosophy during the last two decades as a result of the contributions by Jacques Lacan, Michel Foucault, Jacques Derrida, Gilles Deleuze who developed a cross-disciplinary and comparative approach to interpret the crisis of modernity. They have profoundly influenced feminist studies so that the category of gender has been reassessed in contrast with sex (as a biological connotation) and in relation to history, culture, society. The ideal starting point of my research is the year 1990. I chose it as the approximate historical moment when the intersection of race, class and gender were placed at the forefront of international artistic production concerned with identity, diversity and globalization. Such issues had been explored throughout the 1970s but it was only from the mid-1980s onward that they began to be articulated more consistently. Published in 1990, the book "Gender trouble: feminism and the subversion of identity" by Judith Butler marked an important breakthrough by linking gender to performance as well as investigating the intricate connections between theory and practice, embodiment and representation. It inspired subsequent research in a variety of disciplines, art history included. In the same year Teresa de Lauretis launched the definition of queer theory to challenge the academic perspective in gay and lesbian studies. In the meantime the rise of Third Wave Feminism in the US introduced a racially and sexually inclusive vision over the global situation in order to reflect on subjectivity, new technologies and popular culture in connection with gender representation. These conceptual tools have enabled prolific readings of contemporary cultural production whether fine arts or mass media. After discussing the appropriate framework of my project and taking into account the postmodern globalization of the visual, I have turned to photography to map gender representation both in art and in fashion. Therefore I have been creating an archive of images around specific topics. I decided to include fashion photography because in the 1990s this genre moved away from the paradigm of an idealized and classical beauty toward a new vernacular allied with lifestyles, art practices, pop and youth culture; as one might expect the dominant narrative modes in fashion photography are now mainly influenced by cinema and snapshot. These strategies originate story lines and interrupted narratives using models’ performance to convey a particular imagery where identity issues emerge as an essential part of fashion spectacle. Focusing on the intersections of gender identities with socially and culturally produced identities, my approach intends to underline how the fashion world has turned to current trends in art photography and in some case turned to the artists themselves. The growing fluidity of the categories that distinguish art from fashion photography represents a particularly fruitful moment of visual exchange. Varying over time the dialogue between these two fields has always been vital; nowadays it can be studied as a result of this close relationship between contemporary art world and consumer culture. Due to the saturation of postmodern imagery the feedback between art and fashion has become much more immediate and then increasingly significant for anyone who wants to investigate the construction of gender identity through performance. In addition to that a lot of magazines founded in the 1990s bridged the worlds of art and fashion because some of their designers and even editors were art-school graduates encouraging innovation. The inclusion of art within such magazines aimed at validating them as a form of art in themselves supporting a dynamic intersection for music, fashion, design and youth culture: an intersection that also contributed to create and spread different gender stereotypes. This general interest in fashion produced many exhibitions of and about fashion itself at major international venues such as the Victoria and Albert Museum in London, the Metropolitan Museum of Art and the Solomon R. Guggenheim Museum in New York. Since then this celebrated success of fashion has been regarded as a typical element of postmodern culture. Owing to that I have also based my analysis on some important exhibitions dealing with gender performance like "Féminin-Masculin" at the Centre Pompidou of Paris (1995), "Rrose is a Rrose is a Rrose. Gender performance in photography" at the Solomon R. Guggenheim Museum of New York (1997), "Global Feminisms" at the Brooklyn Museum (2007), "Female Trouble" at the Pinakothek der Moderne in München together with the workshops dedicated to "Performance: gender and identity" in June 2005 at the Tate Modern of London. Since 2003 in Italy we have had Gender Bender - an international festival held annually in Bologna - to explore the gender imagery stemming from contemporary culture. In few days this festival offers a series of events ranging from visual arts, performance, cinema, literature to conferences and music. Being aware that any method of research is neither race nor gender neutral I have traced these critical paths to question gender identity in a multicultural perspective taking account of the political implications too. In fact, if visibility may be equated with exposure, we can also read these images as points of intersection of visibility with social power. Since gender assignations rely so heavily on the visual, the postmodern dismantling of gender certainty through performance has wide-ranging effects that need to be analyzed. In some sense this practice can even contest the dominance of visual within postmodernism. My visual map in contemporary art and fashion photography includes artists like Nan Goldin, Cindy Sherman, Hellen van Meene, Rineke Dijkstra, Ed Templeton, Ryan McGinley, Anne Daems, Miwa Yanagi, Tracey Moffat, Catherine Opie, Tomoko Sawada, Vanessa Beecroft, Yasumasa Morimura, Collier Schorr among others.
