Nina la poliziotta, una donna moderna nel cinema muto italiano

La ricerca, divisa in tre parti, analizza il frammento superstite del film collocandolo nell’ambito del filone dei film “seriali “che si affermano, anche in Italia, parallelamente alle più note esperienze americane, dove emerge un nuovo modello di donna audace ed indipendente. Lo studio si concentra sul restauro e sulla fonte letteraria del film, il romanzo scritto da Carolina Invernizio nel 1909, nonché sul contesto dei romanzi d’appendice a lungo denigrati dalla critica letteraria e oggetto di analisi storiografica e narratologica solo a partire dagli anni Settanta del Novecento. Viene inoltre esaminata la figura della poliziotta dilettante, progenitrice delle detective donne che popolano i prodotti della serialità contemporanea. Si constata che la dimensione filmica libera il personaggio della protagonista dalle maglie ancora retrive della letteratura d’appendice, restituendoci un'immagine femminile dai tratti dinamici e moderni.

Morte e rinascita del cinema. Riflessioni sulle sue crisi economiche

Il cinema è molte cose, una forma d’arte, ma anche un’industria, e come tale ha affrontato diversi ostacoli economici nella sua storia. Fin dagli albori il settore cinematografico è stato scosso da varie crisi economiche, declini, momenti in cui è stata costretta a trasformarsi, a cambiare, per poter sopravvivere. In una situazione così singolare come quella odierna, in cui il cinema sta passando uno dei periodi più difficili per quanto riguarda la sfera economica, ho pensato di svolgere la mia tesi di laurea su quelle crisi che il settore cinematografico ha passato nella sua storia. I momenti storici presi in esame andranno dalla crisi del 1906 fino a quella attuale, causata dalla pandemia di COVID-19, passando per i vari declini produttivi, sia hollywoodiani che italiani. Più che una storia economica del cinema, che richiederebbe molto più spazio, questa tesi analizzerà soltanto i periodi di crisi più significativi, spiegando i motivi che hanno portato al loro scoppio, e facendo dei confronti con l’economia generale. Si vedrà di come in alcuni casi il settore cinematografico abbia seguito l’economia generale e di come in altri sia andato controcorrente, addirittura beneficiandone. Grande importanza avrà il cinema hollywoodiano, di cui si parlerà spesso e lo si considererà come punto di riferimento, ma non mancheranno alcuni capitoli interamente dedicati al cinema italiano, in cui la situazione è stata spesso più delicata e difficile. Verrano presi in esame diversi film usciti nei periodi delle varie crisi, che hanno dato uno sguardo a realtà così decadenti, alle condizioni pietose dei vari lavoratori, o che a volte hanno addirittura cercato di nascondere.

L’occupazione femminile nel settore della produzione audiovisiva in Italia. Un’indagine nell’ambito della serialità sostenuta dall’Emilia-Romagna Film Commission dal 2017 al 2021

Questo lavoro compie un’indagine sulla situazione occupazionale delle donne nel settore della produzione cinematografica e audiovisiva in Italia, con particolare riferimento agli ultimi cinque anni. Il nucleo dello studio è composto da una ricerca che prende come campione di riferimento diciassette opere seriali finanziate dalla Emilia-Romagna Film Commission dal 2017 al 2021. Attraverso le informazioni pervenute dalle crew list e dalle interviste con questionario destinate alle case di produzione coinvolte, si analizza il numero di donne occupate, la composizione di genere nei diversi ruoli, le opinioni dei rispondenti riguardo al tema della parità di genere nel settore. A questi dati si affianca un approfondimento sull’ambito della formazione, prendendo in esame il numero di allieve e allievi di quattro diverse realtà formative nel quinquennio preso in considerazione (la Scuola Nazionale di Cinema, i corsi finanziati dalla Regione Emilia-Romagna attraverso il Fondo sociale europeo, la scuola di Bologna Rosencrantz & Guildenstern, il corso di studi CITEM dell’Università di Bologna), con il fine di individuare congruenze o meno rispetto all’ambito professionale. I risultati di tale indagine vengono preceduti da una panoramica delle attuali politiche a favore della parità di genere nel settore cinematografico e audiovisivo, in particolare attraverso l’osservazione dei criteri di valutazione dei bandi del MiC e della Emilia-Romagna Film Commission.

The dark side of the American dream: la rappresentazione dell'italoamericano nel cinema gangster americano

Lo scopo di questo lavoro di tesi è quello di analizzare come, in una finestra di tempo di circa cento anni, si sia fissato nell’immaginario collettivo la figura dell’italoamericano come gangster. Partendo dalle questioni delle migrazioni, che caratterizzarono l’Italia meridionale a fine Ottocento, e che portarono migliaia di italiani negli Stati Uniti. Sin da subito vennero rappresentati su vignette satiriche come sporchi, ignoranti e ladri. Il cinema non tardò molto a dare la sua rappresentazione, con cortometraggi e successivamente film veri e propri. Con il passare del tempo questi personaggi italoamericani cominciarono ad essere sempre più caratterizzati dai cineasti, facendoli così diventare dei veri e propri miti, prendendo ispirazione dalla realtà, come accadde per i film degli anni Trenta Little Caesar e Scarface, che si basavano su Al Capone. Proprio sui protagonisti di questi due film vennero successivamente ricalcati i personaggi degli anni successivi, ovviamente apportando modifiche e caratterizzandoli maggiormente. Ci troviamo nel periodo del secondo dopoguerra e il genere gangster inizia a fondersi con il noir, caratterizzandosi da nuove sfaccettature, per ovviare anche al problema della censura del codice Hays, che vietava la rappresentazione di etnie in comportamenti immorali. Nella parte conclusiva di questo lavoro di tesi, mi occupo del periodo che va dagli anni Sessanta, caratterizzato da un clima di mutamento e di rivoluzione, sia per quanto riguarda la società americana che per il cinema stesso. Il codice Hays non ha più influenza sui cineasti e, adesso, cineasti italoamericani come Coppola e Scorsese, danno voce alle loro fantasie ed esperienze, abbracciando le loro origini.

Preparation Of An Agar-silver Nanoparticles (a-agnp) Film For Increasing The Shelf-life Of Fruits.

Preparation of protective coating possessing antimicrobial properties is present day need as they increase the shelf life of fruits and vegetables. In the present study, preparation of agar-silver nanoparticle film for increasing the shelf life of fruits is reported. Silver nanoparticles (Ag-NPs) biosynthesised using an extract of Ocimum sanctum leaves, were mixed with agar-agar to prepare an agar-silver nanoparticles (A-AgNp) film. This film was surface-coated over the fruits, Citrus aurantifolium (Thornless lime) and Pyrus malus (Apple), and evaluated for the determination of antimicrobial activity of A-AgNp films using disc diffusion method, weight loss and shelf life of fruits. This study demonstrates that these A-AgNp films possess antimicrobial activity and also increase the shelf life of fruits.

Nitric Oxide-releasing Poly(vinyl Alcohol) Film For Increasing Dermal Vasodilation.

Pathological conditions associated with the impairment of nitric oxide (NO) production in the vasculature, such as Raynaud's syndrome and diabetic angiopathy, have stimulated the development of new biomaterials capable of delivering NO topically. With this purpose, we modified poly(vinyl-alcohol) (PVA) by chemically crosslinking it via esterification with mercaptosuccinic acid. This reaction allowed the casting of sulfhydrylated PVA (PVA-SH) films. Differential scanning calorimetry and X-ray diffractometry showed that the crosslinking reaction completely suppressed the crystallization of PVA, leading to a non-porous film with a homogeneous distribution of -SH groups. The remaining free hydroxyl groups in the PVA-SH network conferred partial hydrophylicity to the material, which was responsible for a swelling degree of ca. 110%. The PVA-SH films were subjected to an S-nitrosation reaction of the -SH groups, yielding a PVA containing S-nitrosothiol groups (PVA-SNO). Amperometric and chemiluminescence measurements showed that the PVA-SNO films were capable of releasing NO spontaneously after immersion in physiological medium. Laser Doppler-flowmetry, used to assess the blood flow in the dermal microcirculation, showed that the topical application of hydrated PVA-SNO films on the health skin led to a dose- and time-dependent increase of more than 5-fold in the dermal baseline blood flow in less than 10min, with a prolonged action of more than 4h during continuous application. These results show that PVA-SNO films might emerge as a new material with potential for the topical treatment of microvascular skin disorders.

Evaluation of the maxillary premolar roots dissociation using radiographic holders with conventional and digital radiography

This in vivo study evaluated the dissociation quality of maxillary premolar roots combining variations of vertical and horizontal angulations by using X-ray holders (Rinn -XCP), and made a comparison between two types of intraoral radiography systems - conventional film (Kodak Insight, Rochester, USA) and digital radiography (Kodak RVG 6100, Kodak, Rochester, USA). The study sample was comprised of 20 patients with a total of 20 maxillary premolars that were radiographed, using the paralleling angle technique (GP), with a 20º variation of the horizontal angle (GM) and 25º variation of the horizontal angle combined with 15º vertical angle (GMV). Each image was independently analyzed by two experienced examiners. These examiners assigned a score to the diagnostic capability of root dissociation and the measurement of the distance between the apexes. Statistical data was derived using the Wilcoxon Signed Rank test, Friedman and T test. The means of the measured distances between buccal and lingual root apexes were greater for the GMV, which ranged from 2.3 mm to 3.3 mm. A statistically significant difference was found between GM and GMV when compared to GP with p < 0.01. An established best diagnostic dissociation roots image was found in the GMV. These results support the use of the anterior X-ray holders which offer a better combined deviation (GMV) to dissociate maxillary premolar roots in both radiography systems.

Juvenile idiopathic arthritis with involvement of the temporomandibular joint: the role of image examinations

PURPOSE: Juvenile idiopathic arthritis (JIA) has unknown etiology, and the involvement of the temporomandibular joint (TMJ) is rare in the early phase of the disease. The present article describes the use of computed tomography (CT) and magnetic resonance (MRI) images for the diagnosis of affected TMJ in JIA. CASE DESCRIPTION: A 12-year-old, female, Caucasian patient, with systemic rheumathoid arthritis and involvement of multiple joints was referred to the Imaging Center for TMJ assessment. The patient reported TMJ pain and limited opening of the mouth. The helical CT examination of the TMJ region showed asymmetric mandibular condyles, erosion of the right condyle and osteophyte-like formation. The MRI examination showed erosion of the right mandibular condyle, osteophytes, displacement without reduction and disruption of the articular disc. CONCLUSION: The disorders of the TMJ as a consequence of JIA must be carefully assessed by modern imaging methods such as CT and MRI. CT is very useful for the evaluation of discrete bone changes, which are not identified by conventional radiographs in the early phase of JIA. MRI allows the evaluation of soft tissues, the identification of acute articular inflammation and the differentiation between pannus and synovial hypertrophy.

An Eulerian Immersed Boundary Method for flow simulations over stationary and moving rigid bodies

The fluid flow over bodies with complex geometry has been the subject of research of many scientists and widely explored experimentally and numerically. The present study proposes an Eulerian Immersed Boundary Method for flows simulations over stationary or moving rigid bodies. The proposed method allows the use of Cartesians Meshes. Here, two-dimensional simulations of fluid flow over stationary and oscillating circular cylinders were used for verification and validation. Four different cases were explored: the flow over a stationary cylinder, the flow over a cylinder oscillating in the flow direction, the flow over a cylinder oscillating in the normal flow direction, and a cylinder with angular oscillation. The time integration was carried out by a classical 4th order Runge-Kutta scheme, with a time step of the same order of distance between two consecutive points in x direction. High-order compact finite difference schemes were used to calculate spatial derivatives. The drag and lift coefficients, the lock-in phenomenon and vorticity contour plots were used for the verification and validation of the proposed method. The extension of the current method allowing the study of a body with different geometry and three-dimensional simulations is straightforward. The results obtained show a good agreement with both numerical and experimental results, encouraging the use of the proposed method.

A biosensor based on immobilization of lactate oxidase in a PB-CTAB film for FIA determination of lactate in beer samples

An amperometric lactate biosensor with lactate oxidase immobilized into a Prussian Blue (PB) modified electrode was fabricated. The advantage of using cetyltrimethylammonium bromide (CTAB) in the electrodeposition step of PB films onto glassy carbon surfaces was confirmed taking into account both the stability and sensitivity of the measurements. The biosensor was used in the development of a FIA amperometric method for the determination of lactate. Under optimal operating conditions (pH = 6.9, E = -0.1 V), the linear response of the method was extended up to 0.28 µmol L-1 lactate with a limit of detection of 0.84 mmol L-1. The repeatability of the method for injections of a 0.28 mmol L-1 lactate solution was 2.2 % (n = 18). The usefulness of the method was demonstrated by determining lactate in beer samples and the results were in good agreement with those obtained by using a reference spectrophotometric enzyme method.

Evaluation of follicular lymphoid depletion in the Bursa of Fabricius: an alternative methodology using digital image analysis and artificial neural networks

Fifty Bursa of Fabricius (BF) were examined by conventional optical microscopy and digital images were acquired and processed using Matlab® 6.5 software. The Artificial Neuronal Network (ANN) was generated using Neuroshell® Classifier software and the optical and digital data were compared. The ANN was able to make a comparable classification of digital and optical scores. The use of ANN was able to classify correctly the majority of the follicles, reaching sensibility and specificity of 89% and 96%, respectively. When the follicles were scored and grouped in a binary fashion the sensibility increased to 90% and obtained the maximum value for the specificity of 92%. These results demonstrate that the use of digital image analysis and ANN is a useful tool for the pathological classification of the BF lymphoid depletion. In addition it provides objective results that allow measuring the dimension of the error in the diagnosis and classification therefore making comparison between databases feasible.

Computational adjustment technique for digital mammographic images based on the digitizer characteristic curve

We evaluated the performance of a novel procedure for segmenting mammograms and detecting clustered microcalcifications in two types of image sets obtained from digitization of mammograms using either a laser scanner, or a conventional ""optical"" scanner. Specific regions forming the digital mammograms were identified and selected, in which clustered microcalcifications appeared or not. A remarkable increase in image intensity was noticed in the images from the optical scanner compared with the original mammograms. A procedure based on a polynomial correction was developed to compensate the changes in the characteristic curves from the scanners, relative to the curves from the films. The processing scheme was applied to both sets, before and after the polynomial correction. The results indicated clearly the influence of the mammogram digitization on the performance of processing schemes intended to detect microcalcifications. The image processing techniques applied to mammograms digitized by both scanners, without the polynomial intensity correction, resulted in a better sensibility in detecting microcalcifications in the images from the laser scanner. However, when the polynomial correction was applied to the images from the optical scanner, no differences in performance were observed for both types of images.
