    Nella prima parte del suo saggio l'autore riflette sugli impieghi del dialetto nel teatro italiano contemporaneo, mettendone in luce gli aspetti non naturalistici, ma espressivi, e constatando l'abbondanza degli esperimenti linguistici del teatro meridionale. Si sofferma, poi, sul caso di Enzo Moscato, caposcuola della nuova avanguardia napoletana, di cui analizza l'opera Signurì Signurì. Di essa si rilevano con puntualità sia i modi pluringustici di una scrittura barocca che mescola registri, stili e idiomi, sia la ossessività dei temi funerei e sessuali. L'insieme dell'opera dell'autore viene letta alla luce di categorie junghiane.In the first part of his paper, the author reflects on the exploitation of dialect in contemporary Italian theatre, highlighting the non naturalistic yet expressive aspects as well as exploring the abundance of linguistic experiments in Southern theatre. It goes on to focus on Enzo Moscazo, a front runner in the new Neapolitan avant-guard, analysing his work entitled Signurì Signurì. From this work both the poly-linguistic methods of Baroque writing that mixes registers, styles and languages, and the obsession with funereal and sexual themes become obvious. The entire works of the author are read in the light of Jungian concepts

    Digital current control of electric arc furnace by parallel modular three-phase IGBT inverters

    Get PDF
    Electric Arc Furnaces (EAF) have been traditionally fed by means of a medium to low voltage transformer (between grid and electrodes), where the main control action consists of modifying the electrodes vertical position. This simple and robust arrangement suffers from grid \u201cpollution\u201d and poor current control. Current control of EAF by means of three phase modular inverters is reported here for the first time. Several control issues are analyzed and addressed, ranging from pure control (e.g. addressing load imbalance and limits due to low switching frequency) to system management. Two different current regulation methods are proposed and compared, namely a scalar approach and a vector method using \u201cquasi zero phase lag\u201d sampling and gains adaptation. The second technique achieves very good control, leading to lower oversizing of the converter stage and process optimization. Simulations have been performed including digital controller architecture, converters and arc electrical behavior. Preliminary experimental measurements are reported based on an actual plant

    Ion beam analysis techniques: a powerful set ge tools for identification and sourcing of ancient gems

    Gemstones are defined as rare minerals having a high clarity, a high hardness and showing a bright colour and a nice shining. The most important gems are diamond, sapphire and emerald. These gems are callad precious stones. Gems have fascinated man since the earliest times. They have always been sought out by man for their aesthetic and symbolic valué. Due to their scarceness and high '^alue, gems were appreciated by the mighty ones as a sign of their power (emperors ^nd kings, dignitaries of religions ...). Their high hardness and henee strong resismnce to deterioration symbolised the everlastingness of their reign. This last property is interesting from an archaeological point of view: gemstones travel through time without noticeable alteration, even buried in aggressive environment. On the other hand, gems oiay be used several times on different jewels, possibly cut and polished again. Like spices and other precious and sought-after items, gems were brought back from long distance. Accordingly, they are good tracers for ancient trading routes and influence of civilisations. Each civilisation had its own favourite gemstones: lapis lazuli in Egypt; amber and emerald in the Román Empire; gamet in early Middle Ages westem civil isations; jade, ruby and sapphire in Far-East cultures. Moreover, the provenance of some ancient gems such as emeralds or gamets is still debated. For all these reasons, the study of gems kept in museum collections is a promising research fíeld

    How Camillo Golgi became "the Golgi"

    Get PDF
    On April 1898 Camillo Golgi communicated to the Medical-Surgical Society of Pavia, the discovery of the "internal reticular apparatus", a novel intracellular organelle which he observed in nerve cells with the silver impregnation he had introduced for the staining of the nervous system. Soon after the discovery it became evident that this cellular component, which was also named the "Golgi apparatus", was a ubiquitous structure in eukaryotic cells. However the reality of the organelle was questioned for years and many cytologists considered the internal reticular apparatus as an artefact due to the fixation and/or metallic impregnation procedure. The controversy was finally solved in the mid-1950s by electron microscopy when the Golgi apparatus definitely acquired its dignity of being a genuine cell organelle. The designation of "Golgi complex" entered officially in the literature in 1956. Both the terms Golgi apparatus and Golgi complex are currently interchangeable. However a quick "the Golgi" and the introduction of Golgi in adjectival form are now prevalent in the blooming scientific literature on the organelle. Thus Camillo Golgi underwent his final transformation and, becoming the eponym of the organelle he had discovered, he found a way to immortality. © 2009 Federation of European Biochemical Societies

    recognition of surface flow processes influenced by roads and trails in mountain areas using high resolution topography

    Get PDF
    AbstractRoad networks in mountainous forest landscapes have the potential to increase the susceptibility to erosion and shallow landsliding. The same issue is observed also for minor trail networks, with evidences of surface erosion due to surface flow redistribution. This could be a problem in regions such as the Italian Alps where forestry and tourist activities are a relevant part of the local economy. This is just one among the several effects of modern anthropogenic forcing: it is now well accepted by the scientific community that we are living in a new era where human activities may leave a significant signature on the Earth, by altering its morphology, and significantly affecting the related surface processes. In this work, we proposed a methodology for the automatic recognition of roads and trails induced flow direction changes. The algorithm is based on the calculation of the drainage area variation in the presence, or in the absence of anthropic features such as roads and trails on hillslopes. T..

    Thermal properties of highly birefringent optical fibres and preforms

    No full text
    Temperature cycling of highly birefringent optical fibers and preforms has been used to investigate the thermal properties of bow-tie and elliptically clad structures. The thermal hysteresis of the birefringence is shown to be a direct consequence of the thermal history of the fiber or preform and has been related to volume changes in the stress-producing borosilicate sections. Annealing increases the axial stress as well as the stress anisotropy and hence the birefringence. Increases of up to a factor of 2 in the birefringence on suitable thermal treatment indicate a new method for further improvement of high birefringence fibers. The implications of the results in the design, fabrication, and use of such fibers are discussed

    Complications of arteriovenous hemodialysis access: Recognition and management

    Get PDF
    English language citations reporting complications of arteriovenous access for hemodialysis are critically reviewed and discussed. Venous hypertension, arterial steal syndrome, and high-output cardiac failure occur as a result of hemodynamic alterations potentiated by access flow. Uremic and diabetic neuropathies are common but may obfuscate recognition of potentially correctable problems such as compression or ischemic neuropathy. Mechanical complications include pseudoaneurysm, which may develop from a puncture hematoma, degeneration of the wall, or infection. Dysfunctional hemostasis, hemorrhage, noninfectious fluid collections, and access-related infections are, in part, manifestations of the adverse effects of uremia on the function of circulating hematologic elements. Impaired erythropoiesis is successfully managed with hormonal stimulation; perhaps, similar therapies can be devised to reverse platelet and leukocyte dysfunction and reduce bleeding and infectious complications

    Which Culture(s) for Europe? The Contrasting Conceptions of the Council of Europe and the European Union from 1949 to the Present Day

    Get PDF
    Two European organizations of a very different nature have taken action to promote and support European culture: the Council of Europe and the European Union. This article aims to show that, despite common symbolic references and mutual influences, the two organizations’ conceptions of culture do not coincide. A socio-historical and comparative analysis of the emergence and evolution of their respective cultural programmes allows us to reconstruct on the long term their visions and usages of culture. Both organizations initially resorted to European culture in a celebratory and legitimizing manner but their approach soon became distinct. The European Commission has durably proposed top-down, elite-driven and static narratives of European culture, which repeatedly drew criticism, also from other actors within the EU institutions. The CoE, on the contrary, has very soon conceptualized culture as open, decentralized and with porous boundaries. These divergent visions will also be observed in the two organizations’ interactions in the cultural domain, which oscillate between competition and collaboration. In contemporary academic debates, the question of the historical and cultural boundaries of Europe are often explored in close connection to the EU’s political agenda and institutional frame. As a contribution to the “provincializing” of the EU, a socio-historical approach including an understudied European organization, the Council of Europe, makes it possible to critically reassess the understanding and usage of culture in the context of European integration
