  5. OPERA's overture

    CERN Document Server

    2006-01-01

    When neutrinos interact, they mainly produce one muon and a shower of hadrons. Here we see two interactions in the heart of the OPERA detector: one in the steel plates of the first magnet (left), the other in the target's scintillation counters (right). OPERA's opening score has been played at the Gran Sasso Laboratory in Italy, and it's in perfect harmony with the melody of the CNGS neutrino beam from CERN, 730 kilometres away. OPERA's overture was played on 18 August 2006, when the first tracks, corresponding to interactions with CNGS neutrinos, were recorded in its detectors. To the great satisfaction of the teams on both of the Alps, the quality of the CNGS beam is fully in line with expectations, as are the first tracks observed by OPERA, which records data with hardly any down time. Over a five-day period, a little over 300 interactions correlated with the CNGS beam were identified, just as predicted. During this first run it has been possible to verify the correct operation of the electronic detector...

    OPERA, the experiment which uses the neutrino beam of CERN’s CNGS facility, has delivered its first neutrino "photos". The core of the detector has been commissioned and has produced images of events resulting from neutrino collisions. The reconstruction of the core (a few cubic millimetres!) of a neutrino interaction at OPERA. The neutrino arriving from the left of the image has interacted with the lead of a brick, producing various particles identifiable by their tracks visible in the emulsion.The snapshot is tiny but it was greeted with enthusiasm by the physicists of OPERA. On 2 October, for the first time, the experiment at the Gran Sasso Laboratory in Italy "photographed" an event produced by the beam of neutrinos sent from CERN, 732 kilometres away. One of the 60,000 photosensitive bricks already installed at the heart of the experiment had produced its first particle track. The commissioning of the OPERA experiment began la...

    2011-01-01

    Three seminars – at CERN, at Gran Sasso and in Japan – and an article calling for the scrutiny of the scientific community: the OPERA Collaboration opened its research publicly. In addition to huge press coverage, this triggered welcome reactions from colleagues around the world, many of whom will attempt to independently interpret and reproduce the measurement. OPERA’s Spokesperson touches base with the Bulletin.   The CERN Main Auditorium was crowded as OPERA Physics co-ordinator Dario Autiero presented the results of their research (23 September 2011). According to the OPERA strategy, the results of the measurements are in the hands of the scientific community and, as for any other scientific result, several months will be needed before other groups will be able to perform an independent measurement. In the meantime, the OPERA Collaboration is dealing with an avalanche of emails from the scientific community, members of the general public, and the press. &...

    2003-01-01

    In the latest in our series of articles on the neutrino beam to Gran Sasso we turn the spotlight this week onto the two experiments under construction at the Gran Sasso Laboratory - OPERA and ICARUS. In March 2003, installation of the OPERA (Oscillation Project with Emulsion tRacking Apparatus) detector began in Hall C of the INFN's Gran Sasso Laboratory in Italy. The OPERA-CNGS1 Collaboration comprises 170 physicists from 35 research institutes and universities worldwide. It is expected that the complete detector will be ready to receive the CNGS neutrino beam and start data acquisition in August 2006. This article gives an overview of the OPERA experiment. The OPERA experiment aims to clear up the mystery of neutrino oscillation. But what are more precisely its objectives ? When cosmic rays interact in the atmosphere, two kinds of neutrino - muon-neutrinos and electron-neutrinos - are produced. In theory there should be twice as many muon-neutrinos as electron-neutrinos, but experiments find too few of the...

    The OPERA experiment was designed to detect ν μ →ν τ oscillations through τ appearance in the CERN Neutrinos to Gran Sasso (CNGS) beam. The detector consists of two identical supermodules, each made by a target section followed by a muon spectrometer. The target sections are made of nuclear emulsion layers alternated to lead plates; a scintillator target tracker is used to locate the neutrino interactions. The muon spectrometers are composed of a dipole iron magnet, precision drift tubes and resistive plate chambers, used as trigger and as tracker. The experiment took data with the neutrino beam from 2006 to 2012, with limited statistics during the first two years. The RPC data taking ended in December 2012. Results about the RPC performance and the aging of the system are briefly presented. The use of the RPC data in the OPERA analysis is also addressed. During the 2012 run, the OPERA RPC system was used to check the measurement of the neutrino velocity with a dedicated set-up in parallel to the standard DAQ of OPERA, to check the preliminary results of 2011 and to improve the precision. For this measurement, the absolute response time of the detector was measured. Finally, RPC data were also used to determine the charge of the third observed τ candidate

    Opera is the most complete form of theatrical representation, characterized by musical accompaniment, both instrumental and vocal. It has played an important role in sociocultural spheres, affecting the various social strata and reflecting customs and ideas in different centuries. Composers have created pieces that have also shown the development of medicine. Since the birth of opera in seventeenth century in Italy, neuroscience has played an important role in influencing the representation of madness and neurological aspects. From the Folly of the Renaissance, a path toward a representation of madness was developed, initially linked to the myths of classical antiquity. In the seventeenth and eighteenth centuries, madness was represented as comical or funny, of a loving nature and influenced by the spread of the Commedia dell'Arte (Comedy of Art). In the nineteenth century, with the rise of the first scientific theories of the mind, insanity took more precise connotations and was separated from other psychiatric and neurological diseases. The operas of the twentieth century depicted psychiatric and neurological diseases, taking into account newer medical and scientific discoveries. © 2015 Elsevier B.V. All rights reserved.

    Full Text Available The OPERA neutrino experiment was designed to perform a unique vτ appearance measurement in the vμ CNGS beam to confirm the oscillation mechanism in the atmospheric sector vμ → vτ. The detection of vτ leptons produced in vτ CC interactions and of their decays is accomplished exploiting the high spatial resolution of nuclear emulsions. Five vτ candidate events have been detected in the full data sample from 2008-2012 CNGS runs, with an expected background of 0.25 events. The background only hypothesis is rejected with a significance larger than 5 σ. The analysis of the tau neutrino sample in the framework of the 3+1 neutrino model is also presented. Furthermore OPERA good capabilities in detecting electron neutrino interactions allow setting limits on the vμ → ve oscillation channel.

    Full Text Available The introductory pages of this contribution deal with one of the main discussions in the field of media studies with a possible impact on an aesthetic interpretation of filmed opera: the opposition between spectacle and narration as described by Andrew Darley. In opposition to Darley’s theory, or its possible application to filmed opera, I posit the hypothesis that the increased visibility of the actions and gestures in filmed opera enhances the audience’s attention to the narrative as one of the salient features of its aesthetic experience. The main section of this article will examine some findings in the fields of cognitive aesthetics and neurosciences as a support for a deeper understanding of the hypothesis proposed above.

    Madness served primarily as a form of amusement for the spectators in operas of the seventeenth century. This representation was far removed from clinical reality. This circumstance changed in the eighteenth century at the time when tragic madness emerged in numerous operas. The opera buffa Arcifanfano-Re dei matti (Arcifanfano-King of fools, premiered in 1749 in Venice, text by Carlo Goldoni 1707-1793 and music by Baldassare Galuppi 1706-1785), which continuously enacts a realm of fools and is meant to appear amusing, is riddled with psychopathological abnormalities for which a retrospective diagnosis is methodologically rejected. However, the opera presents many subjects for working out a typology of fools based on outlasting personality traits of the protagonists. The libretto is investigated. A musical analysis is spared. The conceptualized typology of fools in the opera, which is oriented towards the seven main vices or deadly sins serves, in the tradition of moral satire, to critically hold up a mirror to the audience to reflect their own vices by an amusing characterization of the latter. Historically classified, the treatment of fools by means of isolation, custody, locking up in cages as well as authoritarian measures of submission reflects the custom in those days before humanizing the treatment of people with mental illness in the course of the Enlightenment and the French Revolution. The opera Arcifanfano is essentially characterized by continuous madness. A typology of the fools can be worked out from the precise depiction of the personalities. A mirror is held up to the spectators in terms of vices, in the tradition of the contemporary baroque opera. At the same time, the opera can be classified psychiatrically and historically as a seismograph of its time when in the seventeenth and eighteenth centuries people with mental illness were isolated and incarcerated.

    Full Text Available The increase in the number of psychodiagnostic methods, aimed at the study of the value-semantic sphere confronts researchers with the task of selecting the most reliable and valid instruments. We set the task to conduct psychometric studies of two analogous tools that measure axiological sphere of personality: «Terminal values questionnaire» by I.G. Senin, «Axiological orientation of the personality» test by A.V. Kaptsov & L.V. Karpushina. Scales were checked for internal consistency, and construct validity of questionnaires was studied in greater detail. We offer an approach to the study of construct validity through comparing empirically obtained constructs with theoretical constructs on the basis of objective indicators of interrelations between them.

  3. Interpreting OPERA results on superluminal neutrino

    2012-01-01

    OPERA has claimed the discovery of superluminal propagation of neutrinos. We analyze the consistency of this claim with previous tests of special relativity. We find that reconciling the OPERA measurement with information from SN1987a and from neutrino oscillations requires stringent conditions. The superluminal limit velocity of neutrinos must be nearly flavor independent, must decrease steeply in the low-energy domain, and its energy dependence must depart from a simple power law. We construct illustrative models that satisfy these conditions, by introducing Lorentz violation in a sector with light sterile neutrinos. We point out that, quite generically, electroweak quantum corrections transfer the information of superluminal neutrino properties into Lorentz violations in the electron and muon sector, in apparent conflict with experimental data.

  7. Two orients in Rudolf Bruci's opera Gilgamesh

    2005-01-01

    Full Text Available The theme of this article is the ancient Orient as imagined by the Serbian composer Rudolf Bruci (1917-2002. The finale of his monumental opera Gilgamesh (1986; libretto by Arsa Milošević, makes display of heterogeneous musical material based on different oriental scales. The modernity of the opera is affirmed through the usage of varied techniques of 20th century composition. It is hard to explain why Bruci introduced the well-known medieval church melody "Ninja sili nebesniye" ("Now the celestial powers" into the finale of his opera. The melody was signed by kir Stephan the Serb and has been preserved in a 15th century manuscript. The quotation of "Ninja sili" in the finale of Gilgamesh could be interpreted as an attempt at bridging the many centuries that divide the ancient times that gave birth to the Assyrian myth and our contemporary world, by making reference to the heritage of medieval Serbia when that state was a part of the Byzantine world stretching from the middle East to the Balkans. That compositional gesture of Rudolf Bruci seems to have the meaning of questioning the historical and cultural place and identity of the Serbs through the centuries. If that is correctly interpreted, the composer thus gave his own contribution to the often discussed question of the Serbian belonging to both the East and the West. The "two Orients" in the title of the article are an allusion to the pagan and the Christian Orients, but they can also provoke a discussion of the contemporary divisions between the East and the West.

    The use of nuclear emulsions to record tracks of charged particles with an accuracy of better than 1 micron is possible in large physics experiments thanks to the recent improvements in the industrial production of emulsions and to the development of fast automated microscopes. The European Scanning System (ESS) is a fast automatic system developed for the mass scanning of the emulsions of the OPERA experiment, which requires microscopes with scanning speeds of about 20 cm$^2$/h. Recent improvements in the technique and measurements with ESS are reported.

    2012-03-01

    Acoustic characteristics of classical opera singing differ considerably between the Western and the Chinese cultures. Singers in the classical Peking opera tradition specialize on one out of a limited number of standard roles. Audio and electroglottograph signals were recorded for four performers of the Old Man role and three performers of the Colorful Face role. Recordings were made of the singers' speech and when they sang recitatives and songs from their roles. Sound pressure level, fundamental frequency, and spectrum characteristics were analyzed. Histograms showing the distribution of fundamental frequency showed marked peaks for the songs, suggesting a scale tone structure. Some of the intervals between these peaks were similar to those used in Western music. Vibrato rate was about 3.5Hz, that is, considerably slower than in Western classical singing. Spectra of vibrato-free tones contained unbroken series of harmonic partials sometimes reaching up to 17 000Hz. Long-term-average spectrum (LTAS) curves showed no trace of a singer's formant cluster. However, the Colorful Face role singers' LTAS showed a marked peak near 3300Hz, somewhat similar to that found in Western pop music singers. The mean LTAS spectrum slope between 700 and 6000Hz decreased by about 0.2dB/octave per dB of equivalent sound level. Copyright © 2012 The Voice Foundation. Published by Mosby, Inc.

    2007-10-15

    The Opera experiment will try to confirm the {nu}{sub {mu}} {yields} {nu}{sub {tau}} oscillations by the appearance of the {nu}{sub {tau}} in a pure {nu}{sub {mu}} beam. Indeed, a neutrino beam almost pure is produced at CERN (CNGS Beam) and sent to the Opera detector. The detector is composed of two muons spectrometers and a target formed by walls of bricks. Each brick is an alternation of lead plates and emulsions. This modular structure allows to reconstruct the kink topology of the {tau} lepton decay with a high spatial resolution. The great challenge of the Opera experiment is to detect the {nu}{sub {tau}} interactions with the less uncertainty. To reduce this uncertainty it is essential to identify with the greatest efficiency any background event not including a tau particle. My work permits to reduce background. My principal contribution concerns the selection development, the reconstruction and the muons identification at low energy. This work is based on the setting of variables related to the deposit energy and the multiple scattering. Previously, only deposit energy was used in the analyses of pion/muon separation. This study allows doubling the muon identification efficiency at low energy. This leads to increase the background events rejection in Opera and to decrease the contamination by 30%. I also studied the nuclear emulsions capacity to identify charged particles through the analysis of a test beam carried out by the Nagoya group. This test contains protons and pions with different energies. My work proves that the European scan system gives comparable results with those obtained by the Japanese scan system. (author)

    OPERA is a long baseline neutrino oscillation experiment designed to observe the appearance of vτ in a pure v μ beam in the parameter space indicated by the atmospheric neutrinos oscillation signal. The detector is situated in the underground LNGS laboratory under 3 800 water meter equivalent at a distance of 730 km from CERN where the CNGS neutrino beam to which it is exposed originates. It consists of two identical 0.68 kilotons lead/nuclear emulsion targets, each instrumented with a tracking device and complemented by a muon spectrometer. The concept and the status of the detector are described and the first results obtained with cosmic rays and during two weeks of beam commissioning in 2006 are reported

    OPERA is a unique experiment aimed at the first detection of ν τ appearance in a flux of ν μ due to the neutrino oscillation from ν μ to ν τ . The CERN CNGS beam is the source of ν μ . The detector is hybrid; it is composed of nuclear emulsion films and electronic detectors. It is located in the LNGS underground laboratory. The target consists of 150,000 Emulsion Cloud Chambers (ECC) bricks, which are stacks of interleaved emulsion films and lead plates. The ν τ charged current interactions will be detected by identifying the decay topology of the τ in the ECC bricks. The first run started in 2008. The experiment is currently in the phase of data taking and analysis. The experimental methods, the status and the summary of the results from the 2008 run are presented in this paper.

    Two weeks ago, at a seminar held at CERN, the OPERA collaboration revealed their astonishing observation: neutrinos might move faster than light. The finding is currently under scrutiny in the scientific community. While the result downstream at Gran Sasso speaks for itself, upstream at CERN things are no less intriguing, with high-tech GPS systems, novel techniques for accurately measuring the time, and unique ways keeping the initial particle beam stable. Take away one ingredient and the accuracy needed for the final measurement is spoiled.   Underground installations of the CERN Neutrinos to Gran Sasso (CNGS) project. First ingredient: a stable beam CERN produces neutrinos by sending a beam of protons to hit a target. The collisions produce a secondary beam, which mostly consists of pions and kaons that decay in flight within an evacuated tunnel. Their decay products are muons and muon-neutrinos. An absorber stops the pions and kaons that do not decay, while the resulting muons are absorb...

    Full Text Available Teaching opera in prison presents challenges, such as limits imposed on printed and recorded material to study it, or the audio-visual technology in the classroom space, yet, no other experience can be so inspiring and rewarding for everybody involved. This essay focuses on teaching opera, in particular Mozart’s Don Giovanni, to imprisoned students in America. It addresses pedagogical challenges on how to teach opera in prison and advocates for the need to leave the ivory tower of academia and engage in social action. If opera is still perceived as an elitist art form, it is because it is artificially kept that way by being practiced, taught, studied, and promoted only among an exclusive sector of our population.

    We investigate the implications of non-standard interactions on neutrino oscillations in the OPERA experiment. In particular, we study the non-standard interaction parameter ε μ τ . We show that the OPERA experiment has a unique opportunity to reduce the allowed region for this parameter compared with other experiments such as the MINOS experiment, mostly due to the higher neutrino energies in the CNGS beam compared to the NuMI beam. We find that OPERA is mainly sensitive to a combination of standard and non-standard parameters and that a resulting anti-resonance effect could suppress the expected number of events. Furthermore, we show that running OPERA for five years each with neutrinos and anti-neutrinos would help in resolving the degeneracy between the standard parameters and ε μ τ . This scenario is significantly better than the scenario with a simple doubling of the statistics by running with neutrinos for ten years. (orig.)

Four RPC planes were instrumented and the first tests were performed confirming a good behaviour of the installed RPCs in terms of intrinsic noise and operating currents. The measured noise maps agree with those obtained in the extensive quality tests performed at surface. Counting rates are below 20 Hz/m 2 . Single an multiple cosmic muon tracks were also reconstructed. The estimated efficiency is close to the geometrical limit and the very first measurements of the absolute and differential muon flux are in agreement with expectations

    In 1998 by making use of a water Cherenkov detector the Super-Kamiokande Experiment in Japan has measured a deficit of {nu}{sub {tau}} atmospheric neutrinos without observing a corresponding rise in the {nu}{sub e} flux. This phenomenon is understood as neutrino oscillations, a mechanism implying a non vanishing neutrino mass. In 1999 the CHOOZ Experiment has definitely excluded the oscillations {nu}{sub {mu}} {yields} {nu}{sub e} within atmosphere. The OPERA Experiment aims at evidencing the {nu}{sub {mu}} {yields} {nu}{sub {tau}}oscillations through occurrence of {nu}{sub {tau}} and of {nu}{sub {mu}} {yields} {nu}{sub e} oscillations by occurrence of {nu}{sub e} starting from a muon neutrino beam almost totally clean. Such a beam is actually produced at CERN (CNGS beam) in Switzerland and then directed upon the OPERA detector located 732 km southward under Gran Sasso mountains in Italy. The detector consists of more than 200,000 bricks (what amounts to a total mass of 1,800 tons made up of a nuclear emulsion foils / lead foils sandwich. This module structure allows reconstructing with a high spatial resolution ({delta}{sub {theta}} {approx_equal} 1 mrad and {delta}{sub r} {approx_equal} 1 {mu}m) the kink topology created by the {tau} lepton (issued from charged current interaction of a {nu}{sub {tau}} lepton with a lead nucleus) and its decay products. The work reported in this thesis consists in characterization of the electrons needed in the study of {nu}{sub {mu}} {yields} {nu}{sub {tau}}oscillations, with {tau} {yields} e, and the {nu}{sub {mu}} {yields} {nu}{sub e} oscillations, the {nu}{sub e} interacting through charged currents with a lead nucleus and producing an electron. A reconstruction algorithm of the electromagnetic cascades in nuclear emulsion was developed. This algorithm allows reproducing the longitudinal and transverse profiles used in evaluating the electron energies and their identification as well ({pi}/e separation by mean of a neuron

  9. Opera as Social Showcase: Rituals of “Magic Mirrors” at the Margravial Opera House in Mid-Eighteenth-Century Bayreuth

    Directory of Open Access Journals (Sweden)

    Vlado Kotnik

    2016-04-01

    Full Text Available This article proposes a ritualistic approach to opera in the historical case of the mid-eighteenth-century Margravial Opera House in Bavarian Bayreuth to argue that court opera can be understood as a variety of social showcase. In this view, court opera is a specific form of communication through which opera established the various types of relationship between itself and the social worlds in which, and for which, it was created. By referring to the operatic rituals under the leadership and sponsorship of Wilhelmina of Bayreuth and her husband Frederick, it will be established how the Bayreuth’s ruling couple used opera for several social and political purposes. As both genre and institution, the margravial opera production is interpreted by the analytical models of anthropologists of ritual and theatre, like Victor Turner, Clifford Geertz, Maurice Bloch, Stanley Tambiah, Catherine Bell, employing their ritual theory, especially Turner’s concept of a “hall of magic mirrors”.

    The superluminal neutrinos detected by OPERA indicate Lorentz invariance violation (LIV) of the neutrino sector at the order of 10(-5). We study the implications of the result in this work. We find that such a large LIV implied by OPERA data will make the neutrino production process π → μ + ν(μ) kinematically forbidden for a neutrino energy greater than about 5 GeV. The OPERA detection of neutrinos at 40 GeV can constrain the LIV parameter to be smaller than 3×10(-7). Furthermore, the neutrino decay in the LIV framework will modify the neutrino spectrum greatly. The atmospheric neutrino spectrum measured by the IceCube Collaboration can constrain the LIV parameter to the level of 10(-12). The future detection of astrophysical neutrinos of galactic sources is expected to be able to give an even stronger constraint on the LIV parameter of neutrinos.

    The OPERA experiment, placed 730 km downstream the CERN neutrino beam to Gran Sasso (CNGS) in the LNGS underground laboratory, is designed to measure muon-neutrino to tau-neutrino oscillations in a direct appearance mode. The hybrid apparatus consists of an emulsion/lead target complemented by electronic detectors. Due to the target structure made of thin lead plates, OPERA is able to detect electromagnetic showers, allowing searches for tau electronic decays and for oscillations from muon-neutrino to electron-neutrino. The experimental set-up and associated facilities used to extract data recorded in the emulsion will be described, with the special procedures aimed at locating interaction vertices and detect short decay topologies. OPERA is taking data since 2008. A first nu-tau interaction candidate was already published in 2010. New results with increased statistics will be presented. In particular, an overview of the studies related to electrons will be shown. (author)

  12. Effects of Chinese opera on the reproductions of Ibsen's plays

    2015-02-01

    Full Text Available As part of a globalized phenomenon, the reproductions of Ibsen’s plays on the Chinese theatrical stage increasingly focus upon the exploration and expansion of new cultural forms, as Patrice Pavis defines interculturalism as “grasping the dialectical of exchanges of civilities between cultures”. However, how do we evaluate the effectiveness of the many “intercultural” productions that surround us today? I attempt to answer this question by comparing two Chinese reproductions of Ibsen’s plays that employ elements of Chinese opera on varying scales. The first one is a total transformation of Hedda Gabler into a Hangzhou yue opera form, Xin Bi Tian Gao (Aspirations Higher than the Sky, 心比天高 in 2006. As part of the yue opera tradition, Hedda Gabler was staged in an all-female cast. The second one is a fragmented insertion of a Peking opera excerpt into the staging of A Doll’s House by the National Experimental Theatre of China in 1998. One of the highlights of the play is a Norwegian actress, who plays Nora, singing and dancing a short Peking opera excerpt, thus replacing the tarantella dance in the original play. Contextualising the multiple perspectives towards interculturalism by Patrice Pavis, Richard Schechner and Rustom Bharucha, I aim to explore how the appropriation of Chinese opera in such performances might strengthen or weaken the reciprocal flows between the source and target cultures in Pavis’s “hourglass model”, and whether the initial attempt of revitalising both Chinese and Western art forms has backfired and misproduced Bertolt Brecht’s alienation effect directed at the contemporary audience.

    The OPERA collaboration has reported the observation of superluminal muon neutrinos, whose speed v{sub {nu}} exceeds that of light c, with (v{sub {nu}}-c)/c {approx_equal} 2.5 x 10{sup -5}. In a recent work, Cohen and Glashow (CG) have refuted this claim by noting that such neutrinos will lose energy, by pair-emission of particles, at unacceptable rates. Following the CG arguments, we point out that pair-emissions consistent with the OPERA anomaly can lead to detectable signals for neutrinos originating from decays of highly boosted top quarks at the LHC, allowing an independent test of the superluminal neutrino hypothesis.

    The OPERA loop will allow fuel qualification tests, i.e., irradiations of parts of assemblies sufficiently representative, operating in the nominal conditions of advanced reactors. After a presentation of the general design and of the main characteristics, a brief description of the loop is given: in-pile and out-of-pile part, and connections. The installation of the loop in the core of the OSIRIS reactor involves an adaptation of some components of this last one. Complementary installations will allow larger field of applications concerning the representativity of irradiation conditions and the knowledge of these conditions.

    1999-01-01

    This paper presents an interview with Miguel Sabido, a writer-producer-director of theater and soap operas in Mexico concerning the social uses of commercial soap operas. According to Sabido, television soap operas can play multiple roles in educating the public: 1) melodramatic soap operas represent a mediation between good and bad; 2) soap operas allow people to gossip on different characters, their dilemmas, and create a climate for social change, especially if it centers on key social issues; and 3) soap operas provide role models to emulate. Sabido stressed the importance of a theory-based method for producing drama and mentioned how theoreticians Bentley, Bandura, Maclean, and Jung influenced his writing and production of soap operas. According to Sabido, the social uses of commercial television are possible with socially responsible soap operas.

    In the context of the paradoxical results of the OPERA Collaboration, we have proposed a classical mechanics model yielding the statistically measured velocity of a beam higher than the velocity of the particles constituting the beam. Ingredients of our model necessary to obtain this curious result are a non-constant fraction function and the method of the maximum-likelihood estimation.

  4. Measurement of the neutrino velocity in OPERA experiment

    2013-01-01

    The OPERA neutrino experiment has measured the neutrino velocity using the CERN CNGS beam over a baseline of 730 km. The measurement is based on data taken by OPERA in the years 2009, 2010, 2011. An arrival time of CNGS muon neutrinos with respect to the one computed assuming the speed of light in vacuum of (6.5±7.4(stat.) −8.0 +8.3 (sys.))ns was measured corresponding to a relative difference of the muon neutrino velocity with respect to the speed of light (v−c)/c=(2.7±3.1(stat.) −3.3 +3.4 (sys.))×10 −6 . During spring 2012 the CNGS provided during two weeks a short proton bunched beam dedicated to the neutrino velocity measurement. The OPERA neutrino experiment at the underground Gran Sasso Laboratory has measured the velocity of neutrinos with slightly modified setup compared to 2011 measurements. These modifications increased the timing accuracy and also fixed previous problems. The arrival time of CNGS muon neutrinos with respect to the one computed assuming the speed of light in vacuum has been found to be in agreement with the previous measurement. This result confirms the revised OPERA result and that indeed the neutrino anticipation announced in September 2011 was due to technical problems

  7. Soap operas and the history of fan discussion

    Directory of Open Access Journals (Sweden)

    Sam Ford

    2008-09-01

    Full Text Available For decades, fans of U.S. soap operas have formed social networks surrounding their shows, and they did so even before the concept entered the vernacular. Soap fans, who started on a geographically local scale and built their communities through grassroots efforts, have found a variety of venues to connect with one another over the past several decades. This study looks at the pre-Internet development of these social networks to show how that trajectory relates to the current online community of soap opera fans. Although several scholars have studied soap opera fandom, few have taken an historical approach at understanding the trajectory of soap fandom, a view especially necessary in an era where online social networks are at the center of audience studies and where cornerstone U.S. soap operas are struggling to retain relevance and audience. To fill this gap, I argue that understanding fan networks today requires looking back to previous methods of fan networking. Soaps' longevity (the youngest U.S. soap is more than 20 years old and frequency (all U.S. daytime soaps are daily make them crucial texts in demonstrating how the roots of fan social networks in a pre-Internet era helped shape that fandom's transition onto the Internet, and they also illustrate the continued evolution of these networks as fans move online.

    Full Text Available Soap operas are a cultural phenomenon of recognized importance in Brazilian society. They have come into the atention of investigators since they represent concrete social processes that are not strange to the spectator´s reality. A large variety of social themes have already been discussed in soap operas, characterizing a broad spectrum which covers from daily ordinary events up to controversial situation of rupture, forcing public debate. This investigation at empted to identify and analyze how family arrangements, as well as familial and conjugal daily routine, were portrayed in six soap opera plots exhibited between 2003 and 2008 by Rede Globo network. The data collection was performed by the analysis of the soap operas chapter synopses, and the data was organized and discussed using the classic content analysis technique. The way Brazilian family is portrayed in the weekly TV fiction incorporates new family arrangements, presenting new relationship construction possibilities originated during the last decades, in opposition to the conservative raditions

  14. Superluminal neutrinos at OPERA confront pion decay kinematics.

    Violation of Lorentz invariance (VLI) has been suggested as an explanation of the superluminal velocities of muon neutrinos reported by OPERA. In this Letter, we show that the amount of VLI required to explain this result poses severe difficulties with the kinematics of the pion decay, extending its lifetime and reducing the momentum carried away by the neutrinos. We show that the OPERA experiment limits α=(ν(ν)-c)/c<4×10(-6). We then take recourse to cosmic-ray data on the spectrum of muons and neutrinos generated in Earth's atmosphere to provide a stronger bound on VLI: (ν-c)/c<10(-12). © 2011 American Physical Society

    The OPERA muon magnetic spectrometer has been designed for muon detection, tracking and timing. The 44 bakelite Resistive Chambers (RPC) planes, imbibed inside the magnet iron slabs, must provide the tracking of the muon curved in the magnetic field to ease the momentum and charge measurement provided by the HPT. Furthermore, it provides the momentum for muons stopping in the iron. RPC signals will be also used as start of drift tube acquisition thanks to the very good time resolution of RPC detectors. Due to the required performances the tracking detector must be fully efficient and stable. In this conditions an online monitor is mandatory to continuously control stability of run conditions. We report the main characteristics and performances of the monitor system for the OPERA spectrometer and capabilities of the software developed for settings and data acquisition.

    OPERA is an experiment dedicated to the observation of νμ into ντ oscillations in appearance mode using a pure νμ beam (CNGS) produced at CERN and detected at Gran Sasso. The experiment exploits a hybrid technology with emulsions and electronics detectors. The OPERA readout is performed through a triggerless, continuously running, distributed and highly available system. Its global architecture is based on Ethernet-capable smart sensors with microprocessing and network interface directly at the front-end stage. A unique interface board is used for the full detector reading out ADC-, TDC- or Controller-boards. All the readout channels are synchronized through a GPS-locked common bidirectional clock distribution system developed on purpose in a PCI format. It offers a second line to address all channels and the off-line synchronization with the CNGS to select the events.

    The OPERA experiment has for goal the direct detection of !μ ! !! oscilla- tion, using an hybrid apparatus composed of electronic detectors and nuclear photographic emulsions. A charged particle crossing an emulsion layer ion- izes the medium along its path leaving a latent image which leads, after de- velopment, to a sequence of aligned grains. Nuclear emulsions are analyzed by means of optical microscopes to reconstruct the 3D particle tracks. The OPERA collaboration has developed a dedicated system to scan a large num- ber of emulsions (surface of about 1000 m2). The achieved resolution is "1 μm and "1 mrad allowing to observe directly the short-lived " particles pro- duced in !!CC interactions.

    The OPERA (CNGS1) experiment will study neutrino oscillations; in particular it was designed to observe ν μ →ν τ oscillation signal via the direct observation of ν τ interactions in a target of nuclear emulsions films and lead. The experiment will make use of a high energy ν μ beam (CNGS) produced at CERN and of a detector placed in the Gran Sasso Underground laboratory (LNGS); the sub-micron spatial resolution provided by nuclear emulsions will allow to identify oscillation signal with a very low background level. In these months the OPERA collaboration is carrying out the detector assembly and the physical data acquisition is expected to start in August 2006. In order to cope with the expected neutrino interaction rate and allow a quasi-online analysis of the events, the emulsion read out have to be very fast; the limited number of signal events expected requires to the system high efficiency, purity and precision.

    Within the framework of this diploma thesis the density dependent detection characteristics of the OPERA Precision Tracker are studied at a test set up with two drift tube modules. Measurements of gain, hit eciency, spatial resolution and time{to{distance relation are presented depending on the density, anode voltage and discriminator thresholds. At a constant anode voltage the gain falls with increasing density. Therefore the hit eciency and the spatial resolution decrease with increasing density above 1,70 kg/m 3 . Within the temperature{ uctuations of 6 K inside the LNGS, an uncertainty of the spatial resolution up to 75 m is found. Within these temperature{ uctuations the upper limit for the variation of the drift distance at a drift time of 1200 ns is about 220 m. Both eects are tolerable for the spatial resolution of the OPERA Drift Tubes.

    2010-01-01

    1400 metres underground in the INFN Gran Sasso Laboratory, the Opera experiment has just observed its first candidate for neutrino oscillation – the phenomenon that confirms that neutrinos have mass. It is the first time that an experiment has observed the direct appearance of the new type of neutrinos produced in the oscillation. Opera uses a dedicated beam produced at CERN’s Super Proton Synchrotron (SPS).   Tracks of first candidate event observed by the OPERA experiment. Neutrinos, abundant in cosmic rays, are involved in several of the nuclear reactions that take place in the Sun, and also in radioactive decays. Numerous as they are, they continue to hold many secrets for scientists. One is the fact that the three types of neutrinos—electron, muon and tau neutrinos—can change into each another. This physical phenomenon, known as neutrino ‘oscillations’, was originally described in an article by Bruno Pontecorvo and Vla...

The application to the OPERA experiment, that aims at detecting oscillations between mu neutrino and tau neutrino in the CNGS neutrino beam, is reported in this paper. In order to reduce background due to latent tracks collected before installation in the detector, on-site large-scale treatments of the emulsions ("refreshing") have been applied. Changeable Sheet (CSd) packages, each made of a doublet of emulsion films, have been designed, assembled and coupled to the OPERA target units ("ECC bricks"). A device has been built to print X-ray spots for accurate interconnection both within the CSd and between the CSd and the related ECC brick. Sample emulsion films have been extensively scanned with state-of-the-art automated optical microscopes. Efficient track-matching and powerful background rejection have been achieved in tests with electronic...

    Problem statement: Numerous studies have led researchers to conclude that the socio-demographic profile of the public of classical music appears to be quite generalizable. However, the survey of the opera public, a classical music subgenre that is often associated with theater performances, appears to be much more difficult to quantify and has not yet been the subject of specific investigations (1). The drastic decrease in audience attendance, especially among young people, has led to a radic...

    For decades, fans of U.S. soap operas have formed social networks surrounding their shows, and they did so even before the concept entered the vernacular. Soap fans, who started on a geographically local scale and built their communities through grassroots efforts, have found a variety of venues to connect with one another over the past several decades. This study looks at the pre-Internet development of these social networks to show how that trajectory relates to the current online community...

  9. A short comment on OPERA neutrino velocity measuerement

    CERN Document Server

    Frabetti, Pierluigi

    2011-01-01

    In this report a potential problem in the data analysis of the OPERA experiment is discussed: the main issue is that the quantity "\\partialt" used in the maximum likelihood procedure is not a "true" parameter of the parent-distribution (called PDF in the apaper) but a shift in the x-axis (time scale). This means that the quantity "\\partialt" has to be considered only as systematic effect these error in not simply deducible from a gaussian distribution as stated.

  10. Particle identification by nuclear emulsions in the OPERA experiment

    International Nuclear Information System (INIS)

    Manai, Kais

    2007-01-01

    The OPERA experiment will try to confirm the ν μ →ν τ oscillations by the appearance of the ν τ in a pure ν μ beam. Indeed, a neutrino beam almost pure is produced at CERN (CNGS Beam) and sent to the OPERA detector. The detector is composed of two muons spectrometers and a target formed by walls of bricks. Each brick is an alternation of lead plates and emulsions. This modular structure allows to reconstruct the kink topology of the τ lepton decay with a high spatial resolution. The great challenge of the OPERA experiment is to detect the ν τ interactions with the less uncertainty. To reduce this uncertainty it is essential to identify with the greatest efficiency any background event not including a tau particle. My work permits to reduce background. My principal contribution concerns the selection development, the reconstruction and the muons identification at low energy. This work is based on the setting of variables related to the deposit energy and the multiple scattering. Previously, only deposit energy was used in the analyses of pion/muon separation. This study allows doubling the muon identification efficiency at low energy. This leads to increase the background events rejection in OPERA and to decrease the contamination by 30 pour cent. I also studied the nuclear emulsions capacity to identify charged particles through the analysis of a test beam carried out by the Nagoya group. This test contains protons and pions with different energies. My work proves that the European scan system gives comparable results with those obtained by the Japanese scan system. (Author)

  11. Projecting the voice: observations of audience behaviours in ICT-mediated contemporary opera

    Science.gov (United States)

    Lin, Yu-Wei; Williams, Alan E.

    2014-07-01

    This paper examines how audiences experience live opera performance and the behaviours they exhibit during live-streaming of the performance. It aims to contribute to our understanding of how audiences, who increasingly inhabit an environment saturated with digital media, respond to contemporary opera performance. Based on a comparative study of audience experiences and behaviours during a live opera performance and the streamed opera screening, we investigate whether digital mediation affects audience appreciation, and whether streaming live opera means the same thing to an audience as the unmediated performance. We firstly outline the conception, design and performance of a contemporary opera and its simultaneous streaming to nearby digital screens. Then, we report the evaluation of the project as measured by a mix of qualitative and quantitative methods during the rehearsals, the live performance and the screening. As one of the few social studies of contemporary classical music in Britain, our study of opera audience behaviours sheds light on the challenges and opportunities afforded by digital technologies for opera companies. Understanding how audiences appreciate digital operas offers practical advice on how theatres and opera companies could respond to new forms of digital activities.

  12. Studies on the detection characteristics of the OPERA drift tube spectrometer; Studien zu den Nachweiseigenschaften des OPERA-Driftroehrenspektrometers

    Oldorf, Christian

    2009-07-15

    Within the framework of this diploma thesis the density dependent detection characteristics of the OPERA Precision Tracker are studied at a test set up with two drift tube modules. Measurements of gain, hit efficiency, spatial resolution and time-to-distance relation are presented depending on the density, anode voltage and discriminator thresholds. At a constant anode voltage the gain falls with increasing density. Therefore the hit efficiency and the spatial resolution decrease with increasing density above 1,70 kg/m{sup 3}. Within the temperature-fluctuations of 6 K inside the LNGS, an uncertainty of the spatial resolution up to 75 {mu}m is found. Within these temperature-fluctuations the upper limit for the variation of the drift distance at a drift time of 1200 ns is about 220 {mu}m. Both effects are tolerable for the spatial resolution of the OPERA Drift Tubes. (orig.)

    2016-01-01

    Romantic operas provide a useful tool for historians to understand the perception of some medical disorders that existed during the nineteenth century. Somnambulism was still a mysterious condition during this time, since its pathogenesis was unknown. Hence, it comes as no surprise that somnambulism features in a number of operas, the best known of which are Verdi's 'Macbeth' and Bellini's 'La Sonnambula', both the subject of recent scholarship. Here we examine a more obscure opera in which sleepwalking is depicted. Dating from 1824, 'Il Sonnambulo' by the Italian composer Michele Carafa is based on a libretto by Felice Romani. Although it shares some features with the Verdi and Bellini operas, it also presents original elements. Our analysis of this forgotten opera supports the contention that studying operas can shed light on medical theories and practices, and on how ideas about mind and body disorders were transmitted to the laity in times past. © 2016 S.

  14. Identification and localization of neutrino events in the OPERA detector

    2004-07-01

    The OPERA experiment is designed for the appearance search of ν μ → ν τ oscillations in the parameters indicated by the atmospheric neutrino anomaly. To prove the appearance of ν τ at 732 km from the CERN, an hybrid detector is under construction at the Gran Sasso laboratory. The target, composed by bricks made of lead plates and emulsion sheets, allows the direct observation of the τ lepton produced in ν τ charged current interactions. The tracking, the localization of neutrino events in the target and the muon identification are allowed by trackers located inside the target (scintillators) and in the spectrometer following the target (RPC). The development of algorithms, based on electronic detectors, is necessary to identify the neutrino interaction and to locate the bricks where the interaction occurred. A classification of neutrino events is performed using the identification of the muon produced in ν μ CC and ν τ CC with τ → μ decay. This classification is optimised with tracking informations and also with topological and calorimetric parameters which describe the nature of the interaction (quasi-elastic, deep inelastic); the algorithm of the localization of neutrino event is performed for each category. A tridimensional brick probability map is built and can be exploited to implement sophisticated extraction brick strategies. To conclude, a feasibility study of a test beam experiment OPERETTE is presented. The project was to install a similar OPERA detector in the COMPASS neutrino beam, in the CERN North Area. It was a good opportunity to prepare OPERA for the scanning emulsion films with neutrino events and to test the analysis procedures. (author)

    The OPERA experiment foresees the use of about 3000m2 of RPCs, that will be tested before the installation in a dedicated cosmic ray test facility. The test facility is composed of 2 triggering walls selecting horizontal cosmic rays muons. Each wall houses 64 glass RPCs equipped with 128 horizontal Flat Cable Strips. The z-coordinate is measured with a standard digital chain, while the x-coordinate is obtained by measuring the propagation time of the signals along the strips. In this paper the performance of the trigger walls and the first results of the RPC debug are presented

    This book focuses on opera house acoustics based on subjective preference theory; it targets researchers in acoustics and vision who are working in physics, psychology, and brain physiology. This book helps readers to understand any subjective attributes in relation to objective parameters based on the powerful and workable model of the auditory system. It is reconfirmed here that the well-known Helmholtz theory, which was based on a peripheral model of the auditory system, may not well describe pitch, timbre, and duration as well as the spatial sensations described in this book, nor overall responses such as subjective preference of sound fields and the annoyance of environmental noise.

  20. Nuclear emulsion scanning in opera: methods and results

    CERN Document Server

    Bozza, C.

    2008-01-01

    The design of the OPERA experiment was also motivated and justified by the revival of nuclear emulsion handling and scanning in a modem, automatic fashion, as it took previously place, although at a smaller scale, for the CHORUS experiment. Nuclear emulsions are still the only detector to allow a very detailed topological study of an interaction/decay vertex at the sub-micrometer level. They are most suitable in experiments where topology is a non-ambiguous signature of a certain class of events. This is for instance the case of neutrino oscillation detection and measurement by the study of a tau-appearance signal. The design and performance of the two different scanning systems used in OPERA (ESS and S-UTS) are discussed. Their unique features in terms of speed, precision, background suppression, particle identification, and kinematical reconstruction are shown in close connection with the technical details that make them possible. Unequalled precision, almost vanishing background, and a wealth of informati...

    2017-03-01

    Full Text Available The present study aims to describe the work that Ján Zavarský, one of the most prominent contemporary Slovak scenographers, has done for musical theatre, mainly opera. The author draws on her years of experience as an audience member, production recordings, photographs, scene designs, and other documentation. Her study is the first attempt at mapping the language of expression that Zavarský has created in two decades, especially in cooperation with the directors Martin Otava and Karla Štaubertová. First, the author deals with the process of creation of a scenographic proposal in dialogue with a director, which gives rise to a scenographic and directorial concept of a production. It then proceeds to identifying the characteristic features of Zavarský’s approach to opera scenography, which include the architectural concept of the scene, simplicity of expression, formal and colour stylization, and the connection between scenography and the movement of characters on the stage. The study includes a list of Zavarský’s scenographies and photographs documenting the individual features of his work for musical theatre in approximately ten productions.

  2. On the Testing of Renovations Inside Historical Opera Houses

    2002-11-01

    Due to the large number of historical opera houses in Italy, many theatres have been renovated in the past, but still more will undergo major restoration in the near future. Unfortunately in this context, the quality and protection of acoustics is rarely considered as an issue of its own. As a consequence, the renovations are hardly ever accompanied by proper scientific and technical support. In this paper, the acoustical impact of works inside the Teatro Municipale "R.Valli" in Reggio Emilia, including the restoration of the main hall and the construction of a new acoustic shell, will be dealt with. Surveys were held in the theatre before renovation and were repeated with identical procedure and instruments after its completion. By means of a comparative analysis of the architectural project and of acoustical data, the impact of major changes in the theatre can be predicted. It is shown that this approach can help in drafting an operational scheme for safeguarding the acoustics of historical opera houses.

    Italian operas can provide relevant information on the medical knowledge during the Romantic Age, especially in the field of neuroscience. One of the most renowned operas, "Nabucco" by Giuseppe Verdi (1813-1901) may provide us with some information on the state of knowledge on neuropsychiatric diseases in the first part of the nineteenth century. The main character of this opera, the Assyrian king Nabucco suffers from delirium. Psychic signs and symptoms attributed to Nabucco in Verdi's opera could have been influenced by a better knowledge of neuropsychiatric diseases in the nineteenth century. Furthermore, the representation of Nabucco's mental illness in the opera could also have been influenced by direct experiences of Verdi himself, who seems to have suffered from recurrent depressive episodes in that period, and for the rest of his life. © 2017 S.

    Epron, J P; Coulombeau, B; Fussi, F

    2010-01-01

    The partiturogram is a tool that was defined in the 1990s by Franco Fussi. It aims to display all the music notes of an opera role as a histogram. Several parameters are then calculated in order to define the vocal profile of the role, as well as help the singer choose from various options. We have decided to use this tool to study Norma and Sonnambula, two roles which were specifically written for the same singer described as a dramatic soprano. Over time, both roles have been allocated to radically different voices. The partiturogram confirms the similarity of the vocal types of both roles, but gives no explanation as to the differences in the casting decisions. We have therefore established its limits, and we have submitted a study including new parameters in order to refine the characterization of roles.

    We perform a detailed analysis of the capabilities of the MINOS, ICARUS and OPERA experiments to measure neutrino oscillation parameters at the atmospheric scale with their data taken separately and in combination. MINOS will determine Δm 32 2 and sin 2 2θ 23 to within 10% at the 99% C.L. with 10 kton-years of data. While no one experiment will determine sin 2 2θ 13 with much precision, if its value lies in the combined sensitivity region of the three experiments, it will be possible to place a lower bound of O(0.01) at the 95% C.L. on this parameter by combining the data from the three experiments. The same bound can be placed with a combination of MINOS and ICARUS data alone

    The OPERA experiment at the Gran Sasso underground laboratory is searching for ν μ → ν τ oscillations in appearance mode in the CNGS neutrino beam. Four ν τ candidate events have been found so far, using a sub-sample of data from the 2008-2012 runs. Given the number of analysed events and the low background, ν μ → ν τ oscillations are established with a significance of 4.2 σ. In this paper the data analysis is discussed, with emphasis on the background constraints obtained using dedicated data-driven control samples. We present also the analysis of the τ neutrino and electron neutrino data in the framework of the 3+1 sterile neutrino model. The measurement of the muon charge ratio in the collected cosmic ray sample is also reported. (paper)

    OPERA is an experiment dedicated to the observation of νμ into ντ oscillations through τ appearance exploiting the CNGS beam. The experiment is composed by two identical super-modules, each with a target section (made of emulsion/lead bricks alternated with a scintillator Target Tracker) and a muon spectrometer (instrumented with bakelite RPCs and drift tubes).The RPCs are operated in streamer mode with the gas mixture Ar/C2H2F4/isoC4H10/SF6=75.4/20/4/0.6. The present performances of the RPC detectors are presented and the aging status of the system after four years of operation is described. The sample of events induced by the CNGS neutrino beam as well as a large sample of cosmic rays have also been used to study general properties of streamer-operated RPCs.

    Full Text Available Il saggio, dopo essersi soffermato sulla poetica del silenzio del drammaturgo belga, si propone di approfondire l’analisi del dialogo nell’opera del primo Maeterlinck. Al rifiuto della mimesi classica corrisponde un discorso che ricalca le dinamiche dell’inconscio per arricchirsi di un ulteriore livello di lettura che trascende la comunicazione superficiale necessitata dalla situazione, assumendo un significato universale. Si rileva come la parola recuperi una dimensione prima e si avvalga del non-detto per esprimere ciò che l’insufficienza del linguaggio non può carpire. Ne deriva un dialogo spersonalizzato e monologico, pregno di ripetizioni ed echi, logicamente sconnesso e frammentario, punteggiato da esclamazioni e sospensioni che ne evidenziano l’inquietudine e la di dinamismo.

    Full Text Available This research is an attempt to study the interpretations and decodings of a soap opera called Faseleha by women of Elam. The theoretical approach of this research is that which has been developed in cultural studies to study television audiences. The main question is this: which ideas and values are dominant and taken for granted in Faseleha, and how do audiences (here, women of Elam interpret and decode the preferred reading of the text and which discourses are available for them and inform them in this process. In the first section, we have used semiology to to illuminate the preferred reading of the text and, in the second section, we have studied women readings by way of focused group interview. The findings showed that the audiences read Faseleha very differently and actively, they are not passive consumers.

  19. Characterization of different options of trackers in OPERA detector

    International Nuclear Information System (INIS)

    Moret, Guillaume

    2002-01-01

    Neutrinos were postulated by Pauli during the thirties. These spin-half and massless particles helped to solve the β decay problems. Their study started in the fifties and work is still going on nowadays. This study was lengthy due the difficulty to detect neutrinos and also to a 'strange' phenomenon: we always detect less neutrinos than expected for solar and atmospheric neutrinos. This phenomenon can be explained by oscillation between massive neutrino states. The OPERA project is intended to directly proved this oscillation. To this aim, a ν μ beam is produced at CERN and pointed to Gran-Sasso (Italy), 732 km away. The detector is optimised to reveal the tau neutrino coming from ν μ → ν τ oscillation. This detector of 30 meters length with 2,000 tonnes of target will be built with more than 200,000 bricks of lead and emulsion. Taus are observed after scanning of the emulsions. The bricks must be localized into the wall and this localization is possible with a tracker located downstream of each target wall. The present work was devoted to the determination of the best tracker for OPERA. Three options were studied and a tracker made of plastic scintillator slabs has been chosen. It allows obtaining an efficiency of the localization of the vertex wall of around 80% and an efficiency of the localization of the brick inside the wall of around 80%. As photo detector we have studies HPD with a self-triggerable readout. HPDs have displayed an excellent resolution, a cross talk lower than 2% and a uniformity higher then 98%. A DAQ based on Ethernet was proposed and accepted by the collaboration. In this option, each photon detector is node of the network and can be accessed in a web browser. A prototype with plastic oscillator, a HPD with an self triggerable readout and a DAQ based on Ethernet were built and validated during beam tests. (author)

  20. Alignment of the drift tube detector at the neutrino oscillation experiment OPERA; Alignment des Driftroehrendetektors am Neutrino-Oszillationsexperiment OPERA

    2012-09-15

    The present thesis was composed during the course of the OPERA experiment, which aims to give a direct evidence for neutrino oscillations in the channel {nu}{sub {mu}} {yields} {nu}{sub {tau}}. The OPERA detector is designed to observe the appearance of tau neutrinos in an originally pure muon neutrino beam, the CNGS beam. As important part of the detector the precision tracker (PT), a drift tube detector, consists of 9504 drift tubes in 198 modules. In this thesis, several parts of the slow control of the PT are developed and implemented to ensure operation during data taking over several years. The main part is the geometric calibration, the alignment of the detector. The alignment procedure contains both hardware and software parts, the software methods are developed and applied. Using straight particle tracks, the detector components are geometrically corrected. A special challenge for the alignment for the PT is the fact that at this kind of low-rate experiment only a small number of particle tracks is available. With software-based corrections of the module rotation, a systematic error of 0.2 mrad has been attained, for corrections of translation, a systematic error of 32 {mu}m is reached. For the alignment between two adjacent PT walls, the statistical error is less than 8 {mu}m. All results of the position monitoring system are considered. All developed methods are tested with Monte Carlo simulations. The detector requirements ({Delta}p/p {<=} 0.25 below 25 GeV) are met. The analysis of the momentum measurement for high energies above 25 GeV demonstrates the resulting improvement. The mean momentum is falling significantly using the new alignment values. The significance of the detector alignment becomes most evident in the analysis of cosmic particles. The muon charge ratio R{sub {mu}} is expected not to be angular dependent. The {chi}{sup 2} probability of the measured distribution improves up to 58%. The muon charge ratio was also investigated in

    Full Text Available This essay examines a Korean opera-film Chunhyang (2000 to show how it departs from the standard practice of Western opera-film and how its uniqueness is generated by the characteristics of indigenous Korean opera P'ansori. In spite of its uniqueness, however, Chunhyang shows its affinities with its Western sisters by confirming what has been criticized by many feminist scholars as one of the most serious problems in the Western tradition of cinema, especially Hollywood's classical films: namely, the gendered politics of the voice.

    The purpose of this work is to report the measurement of a time-shift in the OPERA set-up in a way totally independent of the Time-Of-Flight (TOF) measurements of CNGS neutrino events and without the need to know the distance between the two laboratories, CERN and LNGS, where the neutrinos are produced and detected, respectively. The LVD and OPERA experiments are both installed in the same laboratory: LNGS. The relative position of the two detectors, separated by an average distance of ˜ 160 m, allows the use of very high-energy horizontal muons to cross-calibrate the timing systems of the two detectors, using a TOF technique, which, as stated above, is totally independent of the TOF of CNGS neutrino events. Indeed, the OPERA-LVD direction lies along the so-called "Teramo anomaly", a region in the Gran Sasso massif where LVD has established, many years ago, the existence of an anomaly in the mountain structure, which exhibits a low m.w.e. thickness for horizontal directions. The "abundant" high-energy horizontal muons (nearly 100 per year) going through LVD and OPERA exist because of this anomaly in the mountain orography. The total live time of the data in coincidence between the two experiments correspond to 1200 days from mid 2007 until March 2012. The time coincidence study of LVD and OPERA detectors is based on 306 cosmic-horizontal-muon events and shows the existence of a negative time-shift in the OPERA set-up of the order of Δt AB = -(73 ± 9) when two calendar periods, A and B, are compared. The first, A, goes from August 2007 to August 2008 plus the period from January 2012 to March 2012; the second period, B, goes from August 2008 to December 2011. This result shows a systematic effect in the OPERA timing system present from August 2008 until December 2011. The size of the effect, in terms of the cosmic horizontal muons TOF, is comparable with the neutrino velocity excess recently measured by OPERA. It is probably interesting not to forget that with

    We discuss nuclear emulsion detectors, their history, types, scanning techniques as well as their revival key role in the OPERA experiment. Nuclear emulsion can be considered as an analog data storage device from which the automatic scanning system retrieves the data stored in it. The recent improvement of emulsion scanning techniques brings back the nuclear emulsion as one of the most important detectors among all other elementary particle detectors. OPERA uses the ECC technique used previously by the DONUT experiment. As in the OPERA experiment good modularity for a large apparatus is present, the existence of an automatic scanning system and the availability of fast data scan (Net Scan) are the required parameters, which can only be obtained by utilizing the ECC Nuclear emulsion technique. Therefore, the role of nuclear emulsion is very important in the OPERA experiment. (author)

    Full Text Available Soap operas are a popular culture phenomenon around the globe, including the Republic of Armenia (Armenia hereafter, a small ancient and changing society in post-Soviet era. A survey of 292 college students from Yerevan, the capital, as well as the provinces of Armenia was conducted in Yerevan. Employing uses and gratifications theory, this study investigated the students’ reported motives in viewing soap operas in relations to their demographics. The survey yielded three motives for viewing soap operas: to pass time, for pleasure, and for stimulation. Analysis showed that provincial students were more likely to watch soap operas to pass time. The study can serve as a foundation for future studies about media use in Armenia and possibly other post-Soviet societies.

    The Chinese soap opera, Ke Wang, was created by Li Xiaoming between August 1989 and June 1990 and produced at a cost of US$4650 per episode. The characters were drawn from everyday ordinary Chinese life: a traditional and open-minded and caring woman, a typical mother who works hard and loves her children, a highly educated upwardly mobile man who divorces his wife, a professor criticized during the Cultural Revolution, a doctor prejudiced against ordinary people, a kind honest man who marries the divorcee, a friend of the divorcee, a man who is optimistic in spite of bad experiences during the Cultural Revolution, and an excellent medical doctor who also resolves conflicts. The program was very popular, even among Communists, because of its value-based content, the real-life nature of the show, the change from highly restricted programming, the elaborate and supportive media coverage, and dialogue which closely matches audience preferences. The show has been aired by over 100 stations to date and has reached a total estimated audience of 550 million. The sale of television sets has increased since the show's appearance. The script reflects the conflicts between traditional and modern Chinese values. Pro-social values and behaviors are learned from the role models depicted; examples are given of immediate social impact. Ke Wang was a by-product of the Beijing Television Arts Center's interest in designing television programs that are relevant to the lives of ordinary people. The 60-minute scripts dealt with issues such as the status of women, social morality, family harmony, class conflict, responsible parenthood, maintenance of traditional culture, volunteerism, child development, and coping with physical disability. The Chinese government hailed Ke Wang as model television and awarded US$20,000 in prize money to the producers. The Chinese government is planning to produce other entertainment-education soap operas, which raises the problem of blatant, political

    The OPERA experiment was designed to observe ν μ → ν τ oscillations through ν τ appearance at a baseline of 730km in the CNGS beam. Newly developed emulsion analysis technology allows to measure ν e , ν μ and ν τ interactions with the largest emulsion detector ever made. OPERA has detected five ν τ candidates, allowing to reject the background-only hypothesis at 5.1 σ. The parameters for standard and non-standard oscillations are measured and constrained.

    2005-12-01

    Four volunteer members of the chorus of Opera Australia, representing four different voice categories, wore binaural pairs of wireless microphones during a penultimate dress rehearsal on the Opera Theater stage of the Sydney Opera House. From the recordings, data were obtained on sound levels and on the self-to-other ratios (SORs). The sound levels were comparable to those found in loud music in chamber choir performance. The average SOR ranged from +10 to +15 dB. Compared to chamber choirs in other types of room, the SOR values were high. On a separate occasion, the stage support parameters ST1 (early reflections) and ST2 (late reflections) were measured over the whole stage area. ST1 was about -16 dB, which is typical for opera stages, and -20 dB for ST2, which is unusually low. It is concluded that the SOR in the opera chorus depends mostly on choir formation, which is highly variable, and that an opera chorus artist generally can hear his or her own voice very well, but little of the others and of the orchestra. This was confirmed by informal listening to the recordings.

    Full Text Available The Opera of the National Theater in Belgrade was founded in 1920, but it is well known that opera performances were held long before its official opening. Despite the fact that this is the sole opera house in Belgrade (and one of the only two in Serbia, as well as the fact that it did not face any strong audience fluctuation, it is unusual that no one ever tried to investigate and profile its audience. During the last decades we were witnessing the popularization of the opera via various medias, as well as development and extention of the music industry, which surely changed its social status. The aim of the investigation that is going to be presented is to discover if this social life of opera changed its audience and does it still consists of - according to stereotypes - elderly, high educated individuals of certain professions and high material standards, i.e. at which level the opera is present in the private and public sphere of their lives.

    In complex systems such as the nuclear and chemical industry, the importance of human performance related problems is well recognized. Thus a lot of effort has been spent on this area, and one of the main streams for unraveling human performance related problems is the execution of HRA. Unfortunately a lack of prerequisite information has been pointed out as the most critical problem in conducting HRA. From this necessity, OPERA database that can provide operators' performance data obtained under simulated emergencies has been developed. In this study, typical operators' performance data that are available from OPERA database are briefly explained. After that, in order to ensure the appropriateness of OPERA database, operators' performance data from OPERA database are compared with those of other studies and real events. As a result, it is believed that operators' performance data of OPERA database are fairly comparable to those of other studies and real events. Therefore it is meaningful to expect that OPERA database can be used as a serviceable data source for scrutinizing human performance related problems including HRA

  14. Possible Origin Of The Neutrino Speed Anomaly Reported By OPERA

    CERN Document Server

    Dado, Shlomo

    2011-01-01

    Recently the OPERA collaboration reported a measurement of a superluminal speed of muon neutrinos travelling through the Earth's crust between their production site at CERN and their detection site under Gran Sasso, ~730 km away. The measurement was based on the assumption that the pulse shape of the neutrinos from the decay of parent mesons produced in proton-target collisions is the same as that of the incident protons. Here we argue that the effective column density of the target along the beam direction decreases with time during the 10.5 microseconds duration of the proton pulse. This is because of the thermal expansion and expulsion of target material along the beam by the energy-momentum deposition during the 10.5 microseconds pulse. The progresive reduction in the effective column density during the pulse decreases the neutrino production rate per incident proton. It could have advanced the mean production time of the detected neutrinos relative to that calculated from the proton pulse-shape, by an am...

  16. OPERA and MINOS Experimental Result Prove Big Bang Theory Invalid

    The greatest error in the history of science is the misinterpretation of the Michelson-Morley Experiment. The speed of light was measured to travel at the same speed in all three directions (x, y, z axis) in ones own inertial reference system; however, c will always be measured as having an absolute different speed in all other inertial frames at different energy levels. Time slows down due to motion or a gravity field. Time is the rate of physical process. Speed = Distance/Time. If the time changes the distance must change. Therefore, BOTH mirrors must move towards the center of the interferometer and space must contract in all-three-directions; C-Space. Gravity is a C-Space condition, and is the cause of redshift in our universe-not motion. The universe is not expanding. OPERA results are directly indicated; at the surface of earth, the strength of the gravity field is at maximum-below the earth's surface, time and space is less distorted, C-Space; therefore, c is faster. Newtonian mechanics dictate that a spherical shell of matter at greater radii, with uniform density, produces no net force on an observer located centrally. An observer located on the sphere's surface, like our Earth's or a large sphere, like one located in a remote galaxy, will construct a picture centered on himself to be identical to the one centered inside the spherical shell of mass. Both observers will view the incoming radiation, emitted by the other observer, as redshifted, because they lay on each others radial line. The Universe is static and very old.

    Full Text Available Opera Zora D., composed by Isidora Žebeljan during 2002 and 2003, and which was premiered in Amsterdam in June 2003, is the first Serbian opera that had a world premiere abroad. It is also the first Serbian opera that has been staged outside Serbia since 1935, after being acclaimed at a competition organized by the Genesis Foundation from London. Isidora Žebeljan was commissioned (granted financial backing to compose a complete opera with a secured stage realization. The Dutch Chamber Opera (Opera studio Nederland and the Viennese Chamber Opera (Wiener Kammeroper were the co-producers of the first production. The opera was directed by David Pountney, the renowned opera director, while an international team of young singers and celebrated artists assisted the co-production. The opera was played three times in Amsterdam. Winfried Maczewski conducted the Amsterdam Nieuw Ensemble whereas Daniel Hoyem Cavazza conducted the Wiener Kammeroper on twelve performances. The Viennese premier of Zora D. opened the season of celebrations, thus marking the 50th anniversary of the Wiener Kammeroper. The libretto, based on the script for a TV film by Dušan Ristić, was co-written by Isidora Žebeljan, Milica Žebeljan and Borislav Čičovački. Speaking of genre, the libretto represents a mélange of thriller, melodrama and mystery, with elements of fiction. The opera consists of the prologue and seven scenes. The story, set in the present-day Belgrade, also goes back to the 1930’s and the periods interweave. The opera was written for four vocalists: the soprano, the baritone, and two mezzo-sopranos. The chamber orchestra has fifteen musicians. The story: One summer day in 1935, Belgrade poetess Zora Dulijan mysteriously disappears. Sixty years later, Mina, an ordinary girl from Belgrade, quite unexpectedly becomes part of an incredible story, which gradually unravels as time goes by.

    Radioactive waste in the Netherlands is collected, treated and stored by COVRA (Centrale Organisatie Voor Radioactief Afval) in the interim storage facility for at least 100 a. After this period of long-term storage, geological disposal is foreseen. The policy is based on a step-wise decision process in which all decisions are taken to ensure safe disposal in a repository, but without excluding unforeseen alternative solutions that might develop in the future. OPERA is the Dutch acronym for research program into geological disposal of radioactive waste. It started in 2011 and is running for five years. The OPERA Research plan is developed by NRG in close collaboration with COVRA. Radioactive waste disposal in the Netherlands is at an early, conceptual phase. The aim of Opera is to develop a first preliminary safety case to structure the research necessary for the eventual deployment of a repository in the Netherlands. The OPERA research program aims at a close cooperation with the Belgian research program on radioactive waste disposal. The result of OPERA will be to detail a first roadmap for the long-term research on geological disposal of radioactive waste in the Netherlands, based initially on a re-evaluation of existing safety and feasibility studies conducted more than ten years ago, making use of present international and, wherever possible, national knowledge. This will be done by developing initial and conditional safety cases for generic GDFs in Zechstein rock salt and Boom Clay formations in the Netherlands. The goal in OPERA is to develop initial safety cases that are intended to mark the start of the research development process and to iterate these as knowledge grows to new developed insights. The safety case is conditional since plausible assumptions must later be confirmed in a safety case e.g. for site selection. Dutch, Belgian, German, English and French organizations participate in OPERA. These organizations can be found in the two documents with

    Autiero, Dario

    2012-03-01

    The OPERA neutrino experiment at the underground Gran Sasso Laboratory measured the velocity of neutrinos from the CERN CNGS beam over a baseline of about 730 km with much higher accuracy than previous studies conducted with accelerator neutrinos. The measurement was based on high statistics data taken by OPERA in the years 2009, 2010 and 2011. Dedicated upgrades of the CNGS timing system and of the OPERA detector, as well as a high precision geodesy campaign for the measurement of the neutrino baseline, allowed reaching comparable systematic and statistical accuracies and limiting the overall uncertainty on the neutrinos time of flight measurement to 10 ns. The time of flight was measured by comparing the time distributions of neutrino interactions in OPERA and of protons hitting the CNGS target in 10.5 μs long extractions. The above result, indicating an early arrival time of about 60 ns of CNGS muon neutrinos with respect to the one computed assuming the speed of light in vacuum, was confirmed by a test performed using a beam with a short-bunch time-structure allowing to measure the neutrino time of flight at the single interaction level. The OPERA neutrino velocity measurement will be review as well as the latest developments and perspectives.

  3. Apparent Lorentz violation with superluminal Majorana-tachyonic neutrinos at OPERA?

    2012-01-01

    From the controversial data release of the OPERA-CNGS experiment (The OPERA collaboration 2011 arXiv:1109.4897), publicly announced on 23 September 2011 where muonic neutrinos seem to propagate at a speed faster than light, we cast a phenomenological model describing the behaviour of such a tachyonic neutrino, carrying an imaginary mass based on the Majorana tower of particles described in 1932. If the interpretation of OPERA data is correct and considering the strong constraints from the observations of the supernova SN1987a, we show that the tachyonic behaviour of the neutrino can occur only when it is propagating inside matter. Following this idea, within the experimental errors, we fit the data released by OPERA with those of MINOS and by assuming a superluminal propagation inside the matter of SN1987a, confirm our ansatz with stellar structure models of the supernova precursor. Monte Carlo simulations based on this fit agree well with the new OPERA data. Possible violations of Lorentz invariance due to quantum gravity effects have been considered. (paper)

    A new method of momentum measurement of charged particles through Multiple Coulomb Scattering (MCS) in the OPERA lead emulsion target is presented. It is based on precise measurements of track angular deviations performed thanks to the very high resolution of nuclear emulsions. The algorithm has been tested with Monte Carlo (MC) pions. The results are found to describe within the expected uncertainties the data obtained from test beams. We also report a comparison of muon momenta evaluated through MCS in the OPERA lead emulsion target with those determined by the electronic detectors for neutrino charged current interaction events. The two independent measurements agree within the experimental uncertainties, and the results validate the algorithm developed for the emulsion detector of OPERA.

    Nuclear emulsion films record tracks of charged particles with sub-micron accuracy. The development of fully automatized and DataBase-driven scanning system has made possible the use of nuclear emulsions in large mass detectors. The OPERA experiment, indeed, consists of a hybrid apparatus composed by electronic detectors and lead-emulsion structures (ECC) that make OPERA a large massive (1.25 kt) and high granularity detector. The European Scanning System (ESS), one of the two systems specifically developed for the needs of OPERA, is able to scan emulsions with a speed of 20cm 2 /h and with position and angular resolution of 0.1μm and 2 mrad. Thanks to these features we are able to follow back charged particles along their trajectories until the location, reconstruction and analysis of neutrino interaction vertices in a quasi-online way.

    Full Text Available This study discusses Islam representation in Indonesia, focusing on the adaptation of Islamic-mystic magazines into religious soap operas. Its aim is to reveal the norms underlying the adaptation processes. It analyses Hidayah magazine, one of the most popular Islamic-mystic magazine in Indonesia, as the source text, and Rahasia Ilahi, the highestrating religious soap opera, as the target text. The study finds that the basic norm underlying the adaptation processes is market orientation. It determines two subsequent norms, namely the narrative standardization and faithfulness. The flexible narrative sequence in the magazine should be standardized into the fixed cause-effect narrative structure of soap opera. It creates a more specific norm, namely extreme binary opposition. Meanwhile, faithful norm has three aspects, namely adequacy, factual, and Islamic teaching conformity principles. This three-aspects of faithfulness is specific feature of the religious texts translation.

Melalui kolaborasi dengan sejumlah maestro seni, mulai dari seni vokal dan musik Jawa, seni kostum, seni tari, sampai dengan seni instalasi yang digarap oleh para perupa seperti Entang Wiharso, Nindityo Adipurnomo, dan kawan-kawan, boleh dikatakan bahwa Opera Jawa merupakan sebuah fi lm yang sangat peduli akan visualitas. Berdasarkan pada pembacaan semiotis atas karya-karya instalasi ini di dalam konteks adegan-adegan yang terkait, dapat diketahui bahwa signifi kasi karya-karya instalasi ini pada tataran pesan simbolik telah mengedepankan konotator-konotator utama yang berupa fi gur-fi gur retorik seperti metafora, metonimi, simbol, dan personifi kasi; sementara pada dimensi ideologisnya pun tersingkap beberapa petanda konotatif utama yang sangat signifikan perannya bagi proses pemahaman atas film ini.   Kata kunci: seni instalasi, signifi kasi, retorik, ideologi. ABSTRACT The rhetorical and ideological meaning of the installation works in Opera Jawa Film by Garin Nugroho. Opera Jawa fi lm by Garin Nugroho tries to combine many kinds of art fi eld and its genre. The collaborative project carried out by some arts maestros - from the singing art and Javanese music, fashion, and the dancing art, to the installation art which was carried out by some artists, such as Entang Wiharso, Nindito Adipurnomo, and friends – could give the most signifi cant effect to Opera Jawa which pays more attention to visualization. Based on the semiotic reading to the installation works in the contexts of interrelated scenes, it can be known that the signifi cance of the installation works on the symbolic of the message level has emphasized the main connotations which consist of the rhetorical fi gures such as: metaphor, metonymy, symbol, and personifi cation. On the other hand, based on the ideological dimension, the main connotative signs which are regarded

    We report on the study of the sensitivity in the ν μ → ν e oscillation channel of the OPERA detector at the Gran Sasso Laboratory along the CNGS neutrino beamline. An identification procedure for νe events was defined and a full Monte Carlo simulation was used in order to simulate the detection of real events and evaluate the identification efficiency. A cut on the reconstructed neutrino energy was studied with the purpose of improving the sensitivity on the ν μ → ν e oscillation parameters. Finally a further analysis of the OPERA sensitivity in (3+1)-neutrino mixing model was performed.

  18. Definition of the OPERA safety case for radioactive waste disposal in the Netherlands

    2014-01-01

    This paper first gives a short introduction on OPERA, the current Dutch five-year research programme on disposal of radioactive waste. It then zooms in on OPERA WP (Work Package) 2 Safety Case - the OSCAR project, and presents (preliminary) results on the structure of the OPERA safety case, the subject of safety statements, and the OPERA safety assessment methodology. The structure of the initial long-term, post-closure safety case for a disposal facility for radioactive waste in Boom Clay in the Netherlands is being developed in the OSCAR project. Hereto a selection of relevant national and international efforts concerning the set-up of a safety case for geological disposal of radioactive waste (safety case structure, safety assessment methodology, FEP database) has been reviewed considering the objectives and outlines of the OPERA programme described in the OPERA research plan. Not surprisingly, it turned out that the guidelines and databases of the IAEA and NEA developed by the international community pretty well covered all aspects of nationally developed safety cases. Although in OPERA only 'initial and conditional' safety cases (for disposal in low permeable clay and rock salt) will be developed, the programme objective is detailing a first road-map for the long-term research on geological disposal of radioactive waste in the Netherlands. The safety case being developed will serve as a basis for the further development of the subsequent stages of the Dutch radioactive waste disposal programme. The focus of OSCAR is, therefore, to develop and propose a 'future proof' structure for the safety case, drawing on the NEA and IAEA/PRISM methodologies. The OPERA safety case structure being developed will encompass all relevant aspects, or components, of a modern safety case and will link the different components in a practical and transparent way. It will assist in steering the flow of information generated within the different OPERA and as such provide a structured

    Amelino-Camelia, Giovanni; Loret, Niccoló; Mercati, Flavio; Rosati, Giacomo; Lipari, Paolo

    2011-01-01

    We offer a preliminary exploration of the two sides of the challenge provided by the recent OPERA data on superluminal neutrinos. On one side we stress that some aspects of this result are puzzling even from the perspective of the wild quantum-gravity literature, where arguments in favor of the possibility of superluminal propagation have been presented, but not considering the possibility of such a sizeable effect for neutrinos of such low energies. We feel this must encourage particularly severe scrutiny of the OPERA result. On the other side, we notice that the OPERA result is reasonably consistent with $\\mu$-neutrino-speed data previously obtained at FERMILAB, reported in papers of 2007 and 1979. And it is intriguing that these FERMILAB79 and FERMILAB07 results, when combined with the new OPERA result, in principle provide a window on $\\mu$-neutrino speeds at different energies broad enough to compare alternative phenomenological models. We test the discriminating power of such an approach by using as ill...

  7. Event classification with the electronic detectors of the OPERA experiment using neural networks

    International Nuclear Information System (INIS)

    Hierholzer, Martin C.

    2012-02-01

    The OPERA experiment searches for ν μ ν τ oscillations in appearance mode. It uses the emulsion cloud chamber (ECC) technique for a high spatial resolution combined with on-line components for event localisation and muon identification. The analysis of events in an ECC detector takes considerable time, especially in case of ν τ /ν e candidate events. A ranking of events by a probability for being a ν τ /ν e event can speed up the analysis of the OPERA experiment. An algorithm for such an event ranking based on a classification-type neural network is presented in this thesis. Almost all candidate events can be found within the first 30% of the analysed events if the described ranking is applied. This event ranking is currently applied for testing purposes by the OPERA collaboration, a decision on a full application for the whole analysis is pending. A similar neural network is used for discrimination between neutral and charged current events. This is used to observe neutrino oscillations in disappearance mode with the on-line components of the OPERA detector by measuring the energy dependence of the fraction of neutral current interactions. The confidence level of the observed oscillation effect is 87%. Assuming full mixing, the mass splitting has been determined to vertical stroke Δm 2 32 vertical stroke =2.8 -1.7 +1.4 .10 -3 eV 2 .

  12. Somnambulism in Verdi's Macbeth and Bellini's La Sonnambula: opera, sleepwalking, and medicine.

    Finger, Stanley; Sironi, Vittorio Alessandro; Riva, Michele Augusto

    2015-01-01

    The arts can provide unique ways for determining how people not directly involved in medicine were viewing and informing others about physical and mental disorders. With operas, one need only think about how various perturbations of madness have been portrayed. Somnambulism has long been a particularly perplexing disorder, both to physicians and the laity, and it features in a number of operas. Two mid-nineteenth-century masterpieces are examined in detail in this contribution: Verdi's Macbeth and Bellini's La Sonnambula. In the former, the sleepwalking scene is faithful to what Shakespeare's had written early in the seventeenth century, a time of witchcraft, superstition, and the belief that nocturnal wanderings might be caused by guilt. In Bellini's opera, in contrast, the victim is an innocent girl who suffers from a quirk of nature, hence eliciting sympathy and compassion. By examining the early literature on somnambulism and comparing this disorder in these operas, we can see how thinking about this condition has changed and, more generally, how music was helping to generate new ways of thinking about specific diseases and medicine. © 2015 Elsevier B.V.

    Full Text Available RESUMO A operação de colheita mecanizada de sementes demanda que as regulagens das colhedoras sejam dinâmicas, fato que afeta diretamente a qualidade da operação e dos grãos colhidos. Desta forma, o objetivo do presente trabalho foi monitorar, em intervalos regulares de tempo, a qualidade da operação de colheita de sementes de soja realizada simultaneamente por duas colhedoras de grãos, com emprego do controle estatístico de qualidade (CEQ. O trabalho foi realizado em um campo de produção de sementes na região de Catalão, GO, onde foram monitorados o desempenho operacional das colhedoras, as perdas quantitativas na colheita e as perdas qualitativas das sementes. Observou-se que as colhedoras monitoradas operaram em condições semelhantes porém as regulagens na folga do cilindro e na rotação do rotor otimizaram os índices de perdas mantendo a qualidade das sementes colhidas. Assim, todos os índices de perda avaliados, tanto as perdas quantitativas como os valores das perdas qualitativas, se encontraram dentro dos limites de controle estatístico o que permite se atribuir qualidade e confiabilidade para a operação de colheita mecanizada de sementes.

    2015-10-01

    Full Text Available A realização de mais de uma operação da colhedora de café pode aumentar a eficiência de colheita dos frutos, minimizando a quantidade de café remanescente nas plantas e a necessidade de repasse manual. O repasse manual comumente encarece o processo de produção e promove maiores danos às plantas em relação à colheita mecanizada. Entretanto, deve-se conhecer qual número de operações da colhedora é necessário para derriçar completamente os frutos dos cafeeiros, em lavouras que apresentem diferentes cargas produtivas, notadamente as de cargas mais elevadas, por apresentarem maior dificuldade em serem totalmente colhidas. Portanto, objetivou-se, com este trabalho, avaliar o número de operações da colhedora, em duas lavouras de café, para uma colheita eficiente. Foram comparadas duas situações: lavoura com carga intermediária (50,78 sacas de café ben ha-1e lavoura com carga alta (121,54 sacas de café ben ha-1, na região do Cerrado Mineiro, utilizando de uma a seis operações de uma colhedora KTR. Utilizou-se delineamento de blocos ao acaso e quatro repetições. Avaliou-se a quantidade de café caído, remanescente, colhido e eficiência de colheita. Obteve-se que, para que a quantidade de café remanescente nas plantas seja suficiente para dispensar o repasse manual, são necessárias três operações da colhedora de café em cargas elevadas e duas em cargas intermediárias. Independentemente da carga de café, utilizar três ou mais operações da colhedora colhe maior quantidade de frutos, no entanto, sem diferir quanto à eficiência de colheita da colheita com duas operações

  3. Comparing historical and contemporary opera singers with historical and contemporary Jewish cantors.

    This study is an attempt to ascertain if singers from different traditions and milieus follow similar aesthetic trends regardless of training and/or background. Cantors who sang the Jewish synagogue liturgy during the Golden Age of cantorial singing prior to World War II came from Eastern and Central Europe. For the most part, they were not trained in the classical Western opera tradition. They received training from choir leaders and other cantors and the training was primarily in the modes of synagogue chant. Cantors today receive the same kinds of training that opera singers receive, often from the same teachers. Four groups of singers, consisting of four singers in each group, were utilized in this study. The four groups are: historical opera singers, contemporary opera singers, historical cantors, and contemporary cantors. The historical opera singer recordings date from as early as 1909 to as late as 1939. It was not possible to determine the dates of the historical cantor recordings. However, the four cantors chosen for this group were active only to the 1940s. Contemporary samples were taken from CDs and/or live recordings and all the singers from the contemporary groups are either still active or were active in the 1960s through the 1980s and all of them are considered to be premier-level singers in their respective areas. The variables analyzed were: vibrato pulse rate, frequency variation of the vibrato pulse above and below the mean sustained sung frequency in percent, the mean amplitude variation of the amplitude vibrato pulse above and below the mean sustained amplitude in percent and the fast Fourier transform (FFT) power spectrum of the sustained samples. Results indicate that most of the significant differences were found between eras and not between groups within a time period.

    2017-10-01

    Full Text Available The present paper focuses on the issue of translating operatic libretti in the form of surtitles. This is a very specific type of translation, and it becomes even more challenging when operatic productions for which surtitles are created are modernised. In such cases the application of skopos theory proves to be the most useful and effective, even though some of its premises may be regarded as controversial. The data for the present study come from the most reputable opera houses, for example the Metropolitan Opera House or Royal Opera House, as they are known for providing their audiences with high-quality libretti translations.

  5. study of neutrino interactions using the electronic detectors and emulsion-lead targets of the OPERA experiment

    2011-01-01

    OPERA collected muon-neutrino interaction during the 2008, 2009 and 2010 physics run of the CNGS neutrino beam, produced at CERN with an energy range of about 5-35 GeV. A total of 5.3 x 10 19 protons on target equivalent luminosity from the 2008-2009 sample has been analysed using the measurements in the electronic detectors. We report on the OPERA electronic detectors performances and comparison of momentum measurements of soft muon tracks performed by the electronic detectors to the measurement performed in the OPERA neutrino target brick.

  6. Are OPERA neutrinos faster than light because of non-inertial reference frames?

    Science.gov (United States)

    Germanà, C.

    2012-02-01

    Context. Recent results from the OPERA experiment reported a neutrino beam traveling faster than light. The challenging experiment measured the neutrino time of flight (TOF) over a baseline from the CERN to the Gran Sasso site, concluding that the neutrino beam arrives ~60 ns earlier than a light ray would do. Because the result, if confirmed, has an enormous impact on science, it might be worth double-checking the time definitions with respect to the non-inertial system in which the neutrino travel time was measured. An observer with a clock measuring the proper time τ free of non-inertial effects is the one located at the solar system barycenter (SSB). Aims: Potential problems in the OPERA data analysis connected with the definition of the reference frame and time synchronization are emphasized. We aim to investigate the synchronization of non-inertial clocks on Earth by relating this time to the proper time of an inertial observer at SSB. Methods: The Tempo2 software was used to time-stamp events observed on the geoid with respect to the SSB inertial observer time. Results: Neutrino results from OPERA might carry the fingerprint of non-inertial effects because they are timed by terrestrial clocks. The CERN-Gran Sasso clock synchronization is accomplished by applying corrections that depend on special and general relativistic time dilation effects at the clocks, depending on the position of the clocks in the solar system gravitational well. As a consequence, TOF distributions are centered on values shorter by tens of nanoseconds than expected, integrating over a period from April to December, longer if otherwise. It is worth remarking that the OPERA runs have always been carried out from April/May to November. Conclusions: If the analysis by Tempo2 holds for the OPERA experiment, the excellent measurement by the OPERA collaboration will turn into a proof of the general relativity theory in a weak field approximation. The analysis presented here is falsifiable

    Di Capua, F

    2010-01-01

    The OPERA experiment aims at measuring for the first time neutrino oscil- lation in appearance mode through the detection of ni-tau in an almost pure niμ beam produced at CERN SPS (CNGS), 730 km far from the detector. The ni-tau appearance signal is identified through the measurement of the decay daughter particles of the " lepton produced in CC ni-tau interactions. Since the short-lived " particle has, at the energy of the beam, an average decay length shorter than a 1 mm, a micrometric detection resolution is needed. The OPERA appara- tus is hybrid, using nuclear emulsion as high precision tracker and electronic detectors for the time stamp, event localization in the target and muon recon- struction. The Emulsion Cloud Chamber technique fulfils the requirement of a microscopic resolution together with a large target mass. The kinematical analysis allowed by this technique is described.

    Cai, Feilong; Yu, Jinhui

    In this paper we present a real-time interactive system for making facial makeup of Peking Opera. First, we analyze the process of drawing facial makeup and characteristics of the patterns used in it, and then construct a SVG pattern bank based on local features like eye, nose, mouth, etc. Next, we pick up some SVG patterns from the pattern bank and composed them to make a new facial makeup. We offer a vector-based free form deformation (FFD) tool to edit patterns and, based on editing, our system creates automatically texture maps for a template head model. Finally, the facial makeup is rendered on the 3D head model in real time. Our system offers flexibility in designing and synthesizing various 3D facial makeup. Potential applications of the system include decoration design, digital museum exhibition and education of Peking Opera.

    We present an overview of the data acquisition system (DAQ) and event building of OPERA. OPERA is a long baseline neutrino experiment with a high modularity detector and low event rate. To deal with these features a distributed DAQ system base on Ethernet standards for the data transfer has been chosen. A distributed GPS clock signal is used for synchronizations and time stamp of the data. This architecture allows very modular and flexible event building based on a software trigger strategy. We also present its specific application to the spectrometer sub-detector where RPC trackers are installed. Self-triggerability is a dedicated feature to be also sensitive to out-of-spill events and to possibly allow data taking before the official start of the experiment

    No information exists regarding whether a favorite television category choice affects attention, memory, or cognition among older women. Cross-sectional data from a population-based community sample of 289 older cognitively and physically intact women who were surveyed about television use. The cognitive battery included measures of psychomotor speed, executive attention, immediate and delayed verbal memory, and global cognition. Talk shows (P cognitive outcomes in both unadjusted and adjusted analyses. Clinically significant cognitive impairment across domains were associated with watching talk shows (OR = 7.3; 95% CI = 1.9, 28.4) and soap operas (OR = 13.5; 95% CI = 3.7, 49.5). Clinical interviews can incorporate questions about television viewing habits. Endorsements of talk shows or soap operas as frequent and favored television programming may identify those at risk for cognitive impairment and targets for further cognitive screening.

    The OPERA neutrino oscillation experiment is based on the use of the Emulsion Cloud Chamber (ECC). In the OPERA ECC, nuclear emulsion films acting as very high precision tracking detectors are interleaved with lead plates providing a massive target for neutrino interactions. We report on studies related to the effects occurring from the contact between emulsion and lead. A low radioactivity lead is required in order to minimize the number of background tracks in emulsions and to achieve the required performance in the reconstruction of neutrino events. It was observed that adding other chemical elements to the lead, in order to improve the mechanical properties, may significantly increase the level of radioactivity on the emulsions. A detailed study was made in order to choose a lead alloy with good mechanical properties and an appropriate packing technique so as to have a low enough effective radioactivity.

  18. Statistical model uncertainty and OPERA-like time-of-flight measurements

    CERN Document Server

    Riordan, Oliver

    2011-01-01

    Time-of-flight measurements such as the OPERA and MINOS experiments rely crucially on statistical analysis (as well as many other ingredients) for their conclusions. The nature of these experiments leads to a simple class of statistical models for the results; however, which model in the class is appropriate is not known exactly, as this depends on information obtained experimentally, which is subject to noise and other errors. To obtain robust conclusions, this problem, known as "model uncertainty," needs to be addressed, with quantitative bounds on the effect such uncertainty may have on the final result. The OPERA (and MINOS) analysis appears to take steps to mitigate the effects of model uncertainty, though without quantifying any remaining effect. We describe one of the strategies used (averaging individual probability distributions), and point out a potential source of error if this is not carried out correctly. We then argue that the correct version of this strategy is not the most effective, and sugge...

  2. Operações sociais da mente = Social operations of mind

    Directory of Open Access Journals (Sweden)

    Leclerc, André

    2010-01-01

    Full Text Available Thomas Reid introduziu a noção de operação social da mente na teoria da mente e da linguagem. Seu amigo James Gregory desenvolveu essa noção no contexto da Gramática Universal clássica, particularmente na teoria geral dos modos verbais. A gramática filosófica clássica, antes de Reid e Gregory, pressupõe inter alia que a mente é “autocontida” (self-contained; em outras palavras, que os conteúdos e as operações mentais independem do ambiente natural e social. Algumas dessas operações têm uma estrutura em modus/ dictum que corresponde, grosso modo, à distinção atual entre modo psicológico e conteúdo mental conceitual, análoga à distinção entre força ilocucionária e conteúdo proposicional e que se reflete parcialmente no sistema de modos verbais nas línguas naturais. A famosa Gramática de Port-Royal já indicava uma limitação importante desse modelo de mente autocontida: “On ne se commande pas proprement à soimême”, escrevem Arnauld & Lancelot (“Não se ordena propriamente a si mesmo”. Defenderei que Reid percebeu que o individualismo não permite capturar os aspectos sociais da linguagem e, por isso, viu a necessidade de apresentar uma concepção de mente diferente, antiindividualista. A noção de operação social da mente é a peça fundamental da reforma empreendida por Reid em filosofia da mente. Ademais, ele e Gregory defenderam que as linguagens se formaram particularmente para expressar esses aspectos sociais da linguagem e da mente

It uses the emulsion cloud chamber (ECC) technique for a high spatial resolution combined with on-line components for event localisation and muon identification. The analysis of events in an ECC detector takes considerable time, especially in case of {nu}{sub {tau}}/{nu}{sub e} candidate events. A ranking of events by a probability for being a {nu}{sub {tau}}/{nu}{sub e} event can speed up the analysis of the OPERA experiment. An algorithm for such an event ranking based on a classification-type neural network is presented in this thesis. Almost all candidate events can be found within the first 30% of the analysed events if the described ranking is applied. This event ranking is currently applied for testing purposes by the OPERA collaboration, a decision on a full application for the whole analysis is pending. A similar neural network is used for discrimination between neutral and charged current events. This is used to observe neutrino oscillations in disappearance mode with the on-line components of the OPERA detector by measuring the energy dependence of the fraction of neutral current interactions. The confidence level of the observed oscillation effect is 87%. Assuming full mixing, the mass splitting has been determined to vertical stroke {delta}m{sup 2}{sub 32} vertical stroke =2.8{sub -1.7}{sup +1.4}.10{sup -3}eV{sup 2}.

    In this Tech. Note RHIC snakes and stable spin direction $\\vector{n}$0(s) are re-visited, based on OPERA-computed field maps of the former. The numerical simulations so undertaken provide various outcomes regarding RHIC optics and spin dynamics, in relation with orbital and focusing effects resulting from the use of this realistic 3-D representation of the snakes.

    An experiment was conducted comparing two subject groups, each comprised of eight professional singers specializing in a genre of classical music: early music or grand opera. Electroglottography was used to consider vocal characteristics idiomatic to each genre. Whilst there are clear differences in contact quotient between subjects, particularly when relationships between fundamental frequency (f0) and contact quotient (Qx) are considered, there is no apparent link between contact quotient behaviour and performance specialism based on the results of this sample.

  6. OPERA, MINOS Experimental Result Prove Special and General Relativity Theories; the Principle of Lorentz Invariance Invalid

    A great discrepancy exists - the speed of light and the neutrino speed must be identical; as indicated by supernova1987A; yet, OPERA predicts faster-than-light neutrinos. Einstein's theories are based on the invariance of the speed of light, and no privileged Galilean frame of reference exists. Both of these hypotheses are in error and must be reconciled in order to solve the dilemma. The Michelson-Morley Experiment was misinterpreted - my Neoclassical Theory postulates that BOTH mirrors of the interferometer physically and absolutely move towards its center. The result is a three-directional-Contraction, (x, y, z axis), an actual distortion of space itself; a C-Space condition. ``PRESSLER'S LAW OF C-SPACE: The speed of light, c, will always be measured the same speed in all three directions (˜300,000 km/sec), in ones own inertial reference system, and will always be measured as having a different speed in all other inertial frames which are at a different kinetic energy level or at a location with a different strength gravity field'' Thus, the faster you go, motion, or the stronger the gravity field the smaller you get in all three directions. OPERA results are explained; at the surface of Earth, the strength of gravity field is at maximum -- below the earth's surface, time and space is less distorted; therefore, time is absolutely faster accordingly. Reference OPERA's preprint: Neutrino's faster time-effect due to altitude difference; (10-13ns) x c (299792458m) = 2.9 x 10-5 m/ns x distance (730085m) + 21.8m.) This is consistent with the OPERA result.

  7. Development of an automatic scanning system for nuclear emulsion analysis in the OPERA experiment and study of neutrino interactions location

    Following Super Kamiokande and K2K experiments, Opera (Oscillation Project with Emulsion tracking Apparatus), aims to confirm neutrino oscillation in the atmospheric sector. Taking advantage of a technique already employed in Chorus and in Donut, the Emulsion Cloud Chamber (ECC), Opera will be able to observe the ν μ → ν τ oscillation, through the ν τ appearance in a pure ν μ beam. The Opera experiment, with its ∼ 100000 m 2 of nuclear emulsions, needs a very fast automatic scanning system. Optical and mechanics components have been customized in order to achieve a speed of about 20 cm 2 /hour per emulsion layer (44 μm thick), while keeping a sub-micro-metric resolution. The first part of this thesis was dedicated to the optimization of 4 scanning systems at the French scanning station, based in Lyon. An experimental study on a dry objective scanning system has also been realized. The obtained results show that the performances of dry scanning are similar with respect to the traditional oil scanning, so that it can be successfully used for Opera. The second part of this work was devoted to the study of the neutrino interaction location and reconstruction strategy actually used in Opera. A dedicated test beam was performed at CERN in order to simulate Opera conditions. The obtained results definitely confirm that the proposed strategy is well adapted for tau search. (author)

    The OPERA experiment is based on a hybrid technology combining electronic detectors and nuclear emulsions. OPERA collected muon-neutrino interactions during the 2008 and 2009 physics runs of the CNGS neutrino beam, produced at CERN with an energy range of about 5-35 GeV. A total of $5.3 \\times 10^{19}$ protons on target equivalent luminosity has been analysed with the OPERA electronic detectors: scintillator strips target trackers and magnetic muon spectrometers equipped with resistive plate gas chambers and drift tubes, allowing a detailed reconstruction of muon-neutrino interactions. Charged Current (CC) and Neutral Current (NC) interactions are identified, using the measurements in the electronic detectors, and the NC/CC ratio is computed. The momentum distribution and the charge of the muon tracks produced in CC interactions are analysed. Calorimetric measurements of the visible energy are performed for both the CC and NC samples. For CC events the Bjorken-$y$ distribution and the hadronic shower profile ...

    Full Text Available The appropriateness of Christian themes in the performing arts has often been debated. Defenders have argued that various media, including drama, can serve as instruments of spiritual edification, while critics have contended that such efforts often eventuate in sacrilege and a vulgarising exploitation of the sacred for commercial and entertainment purposes. A heated debate took place in 1903 when Richard Wagner’s opera Parsifal, which since its première at Bayreuth in 1882 had been hailed as a magnificent representation of redemption and other themes central to Christianity, was staged at the Metropolitan Opera House in New York – its first performance as an opera outside its original venue. Numerous clergymen and lay people in several denominations sought to have the production banned and cautioned fellow Christians against seeing it. Others, generally of a theologically more liberal bent, defended the work. The heated public controversy is placed into historical context and compared with the history of Parsifal in the United Kingdom, where it was widely appreciated without noteworthy opposition.

    OPERA is a massive lead/emulsion target for a long-baseline neutrino oscillation search. More than 90% of the useful experimental data in OPERA will be produced by the scanning of emulsion plates with the automatic microscopes. The main goal of the data processing in OPERA will be the search, analysis and identification of primary and secondary vertices produced by neutrino in lead-emulsion target. The volume of middle- and high-level data to be analysed and stored is expected to be of the order of several Gb per event. The storage, calibration, reconstruction, analysis and visualization of this data is the task of FEDRA system written in C ++ and based on ROOT framework. The system is now actively used for processing of test beams and simulation data. Several interesting algorithmic solutions permits us to make effective code for fast pattern recognition in heavy signal/noise conditions. The system consists of the storage part, intercalibration and segments linking part, track finding and fitting, vertex finding and fitting and kinematical analysis parts. Kalman Filtering technique is used for tracks and vertex fitting. ROOT-based event display is used for interactive analysis of the special events. iltering technique is used for tracks and vertex fitting.

    The OPERA experiment aims at the direct observation of ν_mu -> ν_tau oscillations in the CNGS (CERN Neutrinos to Gran Sasso) neutrino beam produced at CERN; since the ν_e contamination in the CNGS beam is low, OPERA will also be able to study the sub-dominant oscillation channel ν_mu -> ν_e. OPERA is a large scale hybrid apparatus divided in two supermodules, each equipped with electronic detectors, an iron spectrometer and a highly segmented ~0.7 kton target section made of Emulsion Cloud Chamber (ECC) units. During my research work in the Bologna Lab. I have taken part to the set-up of the automatic scanning microscopes studying and tuning the scanning system performances and efficiencies with emulsions exposed to a test beam at CERN in 2007. Once the triggered bricks were distributed to the collaboration laboratories, my work was centered on the procedure used for the localization and the reconstruction of neutrino events.

    The OPERA neutrino experiment at the underground Gran Sasso Laboratory has measured the velocity of neutrinos from the CERN CNGS beam over a baseline of about 730 km. The measurement is based on data taken by OPERA in the years 2009, 2010 and 2011. Dedicated upgrades of the CNGS timing system and of the OPERA detector, as well as a high precision geodesy campaign for the measurement of the neutrino baseline, allowed reaching comparable systematic and statistical accuracies. An arrival time of CNGS muon neutrinos with respect to the one computed assuming the speed of light in vacuum of ( {6.5± 7.4( {stat.} )_{-8.0}^{+8.3}( {sys.} )} )ns was measured corresponding to a relative difference of the muon neutrino velocity with respect to the speed of light {{{( {\\upsilon -c} )}} / {c} .}=( {2.7± 3.1( {stat.} )_{-3.3}^{+3.4}( {sys.} )} )× {10^{-6 }} . The above result, obtained by comparing the time distributions of neutrino interactions and of protons hitting the CNGS target in 10.5 μs long extractions, was confirmed by a test performed at the end of 2011 using a short bunch beam allowing to measure the neutrino time of flight at the single interaction level.

    OPERA (Oscillation Project with Emulsion-tracking Apparatus) is a neutrino beam experiment located in hall C of the Gran Sasso underground laboratory (LNGS), in Italia, under a equivalent of 3.8 km water (corresponding to a cut at 1.5 TeV for the muons). The first purpose of OPERA is the direct observation of the ν μ → ν τ oscillation in the atmospheric sector observing a ν τ appearance 730 km away from the target in a quasi pure ν μ beam (CNGS). OPERA is an hybrid detector with an instrumented target part (about 125000 bricks made with emulsion and lead sheets) and a spectrometer. Collecting data started in 2006 and 55000 events have been recorded. The first ν τ candidate have been observed this year. The work done during this thesis is oriented around three main topics: Define the trigger rules of the target tracker acquisition system for beam neutrino events, synchronise target tracker and RPC elements, implement the results inside the simulation and the study of the feasibility of an atmospheric neutrino analysis using o-beam data. The new trigger rules succeeds to reach the values of OPERA proposal, i.e. a trigger efficiency greater than 99%. This improvement have been done thanks to coincidence time windows with the CNGS beam during which lower cut are applied, allowing low multiplicity events to be kept. A deep study of electronic detectors intercalibration makes possible the target tracker and RPC data synchronisation. The analysis results are now included in the official simulation. This calibration work have been then used for a study of 'off-beam' atmospheric neutrino oscillation thanks to the selection of up-going particles. The analysis shown in the thesis has improved the OPERA detector understanding and demonstrates the feasibility of an observation of phenomena independent from the Cgs beam. Analysis on atmospherics neutrino detection and muons flux characterisation (seasonal variations for example) are now possible thanks to the

    The commissioning and the proof of functionality of the Precision Tracker of the OPERA experiment is subject of this thesis. The timing system of the precision tracker is of major concern here. At first the time.resolution of the timing electronics was characterized additionally general running parameters were studied. Afterwards the installation and commissioning were carried out. The precision tracker is supposed to determine the momentum of throughgoing myons with an accuracy of {delta}p/p<0.25 as well as the sign of their charge. The commissioning is finished by now and it was shown, that the data acquisition system runs very reliable and only 1.5% show an slightly higher number of hits. The nominal spatial track resolution of {sigma}<600 {mu}m was also reached. (orig.)

The pattern of the use of religious symbols, either verbal or non-verbal symbols are generally explicit, but when examined using appropriate methods, they are actually contained some implicit meanings. The purpose of this study was to discover about how Islam is represented on television religious soap opera using religious symbols and to find out the dominant ideology behind the representation techniques. To analyze the soap operas consist of twenty episodes, the researcher used a semiotic approach by John Fiske on television codes. The results of this study are: (1 the use of verbal symbols to represent Islam potentially creates multiple interpretations when they are spoken by different characters. (2 Some religious terminologies are often used by antagonist player to express anger and disappointment. (3 The soap opera is dominated by verbal violence used by both protagonist and antagonist players, while antagonist player use violence both in verbal and non-verbal forms. The findings about ideology embedded in the soap opera are: (1 capitalist-materialistic ideology, (2 ideology of patriarchy, and (3 violence domination.

  19. Determination of Magnet Specification of 13 MeV Proton Cyclotron Based on Opera 3D

    Full Text Available The magnet is one of the main components of a cyclotron, used to form a circular particle beam trajectories and to provide focusing of the beam. To support the mastery of 13-MeV proton cyclotron technologies, cyclotron magnet design must be done to satisfy cyclotron magnet requirements. This research was conducted by studying important parameters in designing the cyclotron magnet which is then used to determine the design requirements. The magnet design was based on the results of a 3D simulation using Opera 3D software. Opera 3D is a software developed by Cobham plc to solve physical problems in 3D such as magnetostatic using finite element methods. The simulation started by drawing a 3D model of the magnet using a modeler, followed by magnetic field calculations by Tosca module in the Opera 3D software. Simulation results were analyzed with the Genspeo software to determine whether the parameters of the cyclotron magnet have met design requirements. The results indicate that the magnet design satisfied the cyclotron magnet design requirement, that B in the median plane of the magnetic pole approached the isochronous curve, providing axial and radial focusing beam, crossing the resonance line at vr = 1 when the particle energy is low and the particle energy is more than 13 MeV, and lead to small enough phase shift of about 13°. The dimension of the cyclotron magnet is 1.96 m × 1.30 m × 1.21 m; its weight is 17.3 ton; its coil current is 88,024 ampere-turn; its center magnetic field is 1.27479 T; its maximum magnetic field is 1.942116 T; its minimum magnetic field is 0.7689 T; its valley gap is 120 mm; its hill gaps are 40 to 50.78 mm; and its hill angles are 35° to 44°.to 44°

  20. The reconstruction of tracks with the drift tubes in the muon spektrometers of the neutrino experiment OPERA; Die Spurrekonstruktion fuer das Driftroehren-Myon-Spektrometer des Neutrino-Experiments OPERA

    Wonsak, B.S.

    2007-11-15

    In this thesis the reconstruction of tracks within the OPERA muon spectrometer is described as well as parts of the simulation software concerning the drift tubes. A method minimising the {chi}{sup 2} of the tracks is used for the fit, which is supported by liklyhood considerations during the pattern recognition. An analytical description of the time to distance relation for the OPERA drift tubes is introduced to be used in the fit. For simulated events of cosmics a resolution of 410{+-}4 {mu}m and an efficiency of more that 93% has been acquired. For real cosmic data from the OPERA detector a resolution o 374{+-}3 {mu}m and an efficiency of up to 84% has been reached. The acquired angular resolution of 1,2 mrad is sufficient to achieve a momentum resolution of 25% up to momentums of 25 GeV. (orig.)

    2009-01-01

    OPERA is a long baseline neutrino oscillation experiment built to provide the final and unambiguous proof of the neutrino oscillation hypothesis in the atmospheric sector by observing ν τ emerging from the CNGS ν μ beam. The detector is a hybrid apparatus installed in the Hall C of the underground Gran Sasso National Laboratory in Italy. Runs with CNGS neutrinos were successfully carried out in 2007 and 2008. In this paper the detector and the analysis strategy are briefly described and the status of the analysis of the 2008 run events is discussed.

    The hypothesis of neutrino flavour changing in weak interaction representation via oscillations is confirmed by several experiments, all based on the observation of the disappearance of a given neutrino flavour. The direct appearance of a flavour different from the initial one, was never observed so far. OPERA is the first long baseline neutrino oscillation experiment employing nuclear emulsions for the direct observation of tau neutrinos in the CERN to Gran Sasso muon neutrino beam. At present the experiment is in the data taking phase. The number of detected neutrino interactions have exceeded one thousand. Experiment status and a summary of results from 2007 and 2008 runs is presented in this paper.

  7. Analysis of the OPERA-15 two-dimensional voiding experiment using the SAS4A code

    International Nuclear Information System (INIS)

    Briggs, L.L.

    1984-01-01

    Overall, SAS4A appears to do a good job for simulating the OPERA-15 experiment. For most of the experiment parameters, the code calculations compare quite well with the experimental data. The lack of a multi-dimensional voiding model has the effect of extending the flow coastdown time until voiding starts; otherwise, the code simulates the accident progression satisfactorily. These results indicate a need for further work in this area in the form of a tandem analysis by a two-dimensional flow code and a one-dimensional version of that code to confirm the observations derived from the SAS4A analysis

    Directory of Open Access Journals (Sweden)

    Jean-Philippe Héberlé

    2009-11-01

    Full Text Available The aim of this paper is to deal with Opera Box’s recent attempt at creating a contemporary popular opera. The plot and subject of Tower, Alun Hoddinott’s latest opera, are based on the real sequel of events which led the minors of Tower Colliery to buy out their pit. The project of this opera was launched by Opera Box, a mid-scale touring opera company, whose main purpose is to make opera popular through performances of famous works and workshops. With Tower, they have decided for the first time to stage a new opera whose premiere was on October 23, 1999 at Swansea Grand Theatre. All the ingredients are there to make the opera successful. Although the aim of the enterprise is to create a popular opera, this does not mean that the composer and the librettist have not made a real opera. On the contrary, music is there to serve the drama and the music presents all the qualities one should expect from a contemporary composer whose style is not devoid of references to tonality. Added to this, we should bear in mind that both the efficiency of the libretto and the traditional symbolical use of the singers’ tessituras contribute to make of Tower an opera which respects the main features of the genre. In spite of all its musical and dramatic qualities, there have been few performances of Tower and Opera Box has never succeeded in securing any staging of it in London.

    Janicskó-Csáthy, József

    The OPERA (Oscillation Project with Emulsion tRacking Apparatus ) experiment or CNGS1 was approved in 2001 by CERN and presently is under construction. Data-taking is expected to start in 2006. The experiment is designated to the νμ  ντ oscillation search. OPERA is a hybrid detector comprising a number of electronic detectors and a specially designed nuclear emulsion stack interlaced with lead plates. The total target mass of the detector will be about 1.8 kt. This impressive mass needed for neutrino detection is combined with an even more impressive spatial resolution of about a m , characteristic of the nuclear emulsion technique. The detection of ντ is based on the observation of the decay of the τ lepton. The fine grained structure of nuclear emulsions offers the possibility to directly observe such a decay and by the means of kinematical analysis can be clearly separated from background events. Nuclear emulsions will be produced and processed in industrial quantities and the readout will be don...

  20. Neutrino velocity measurement with the OPERA experiment in the CNGS beam

    2011-05-01

    The thesis concerns the measurement of the neutrino velocity with the OPERA experiment in the CNGS beam. There are different theoretical models that allow for Lorentz violating effects which can be investigated with measurements on terrestrial neutrino beams. The MINOS experiment published in 2007 a measure on the muon neutrinos over a distance of 730 km finding a deviation with respect to the expected time of flight of 126 ns with a statistical error of 32 ns and a systematic error of 64 ns. The OPERA experiment observes as well muon neutrinos 730 km away from the source, with a sensitivity significantly better than MINOS thanks to the higher number of interactions in the detector due to the higher energy beam and the much more sophisticated timing system explicitly upgraded in view of the neutrino velocity measurement. This system is composed by atomic cesium clocks and GPS receivers operating in 'common view mode'. Thanks to this system a time-transfer between the two sites with a precision at the level of 1 ns is possible. Moreover, a Fast Waveform Digitizer was installed along the proton beam line at CERN in order to measure the internal time structure of the proton pulses that are sent to the CNGS target. The result on the neutrino velocity is the most precise measurement so far with terrestrial neutrino beams: the neutrino time of flight was determined with a statistical uncertainty of about 10 ns and a systematic uncertainty smaller than 20 nano-seconds.

  2. The brain of opera singers: experience-dependent changes in functional activation.

    Several studies have shown that motor-skill training over extended time periods results in reorganization of neural networks and changes in brain morphology. Yet, little is known about training-induced adaptive changes in the vocal system, which is largely subserved by intrinsic reflex mechanisms. We investigated highly accomplished opera singers, conservatory level vocal students, and laymen during overt singing of an Italian aria in a neuroimaging experiment. We provide the first evidence that the training of vocal skills is accompanied by increased functional activation of bilateral primary somatosensory cortex representing articulators and larynx. Opera singers showed additional activation in right primary sensorimotor cortex. Further training-related activation comprised the inferior parietal lobe and bilateral dorsolateral prefrontal cortex. At the subcortical level, expert singers showed increased activation in the basal ganglia, the thalamus, and the cerebellum. A regression analysis of functional activation with accumulated singing practice confirmed that vocal skills training correlates with increased activity of a cortical network for enhanced kinesthetic motor control and sensorimotor guidance together with increased involvement of implicit motor memory areas at the subcortical and cerebellar level. Our findings may have ramifications for both voice rehabilitation and deliberate practice of other implicit motor skills that require interoception.

    Concern has been expressed about the potentially contagious effect of television soap opera suicides and suicidal language in social media. Twitter content was analyzed during the week in which a fictional assisted suicide was broadcast on a British television soap opera, "Coronation Street." Tweets were collected if they contained language indicating possible suicidal intent or used the word suicide. The modified Thompson tau method was used to test for any differences in the volume of tweets in both categories on the day of screening. Content analysis broke down the use of the word suicide into six thematic categories. There was no evidence on the day of screening of an increase in tweets expressing possible suicidal intent but there was an increase in tweets containing the word suicide. Content analysis found the most common thematic category to be information or support, followed by the raising of moral issues in relation to suicide. It is possible that for certain high-profile media events Twitter may be used more as a civic reactive forum than as a medium for introspection or disclosure of distress.

    2005-01-01

    Full Text Available In this article the writer investigates the relations between perceptions of the East and the West in nineteenth century Greece, their connection to national identity, to the language question and to political tendencies. The composer Manoles Kalomoires was influenced by a group of progressive intellectuals striving to liberate Greek literature and language from its dependence on Ancient Greek legacy, a dependence motivated by Western idealists (who saw in the Greek Revolution of 1821 a renaissance of Ancient Greece. Most were educated in the West, but promoted an oriental image of Greeks. Kalomoires' musical expression of this image was inspired by Rimsky-Korsakov's Sheherazade and the Golden Cockerel. In 1909-910 he wrote an unfinished opera, Mavrianos and the King, on the model of the Golden Cockerel. He later used this music in his best known opera, The Mother's Ring (1917. In the present article the similarities in the three works are for the first time shown. An essential influence from Rimsky-Korsakov's work is the contrast between the world of freedom, nature and fantasy and that of oppression.

    The OPERA hybrid detector, designed to prove neutrino oscillations in the νμ →ντ channel, was exposed to the CNGS νμ beam at a distance of 730 km from the neutrino source. Profiting of the tracking capabilities of its Emulsion Cloud Chamber system, OPERA can perform also a search for νμ →νe oscillations. Current results are compatible with the non-oscillation hypothesis in the three flavour mixing model. The same data allow to constrain the non-standard oscillation parameters θnew and Δmnew2 indicated by the LSND and MiniBooNE experiments.

    Directory of Open Access Journals (Sweden)

    Gilles Couderc

    2009-10-01

    Full Text Available The composition of Benjamin Britten’s sixth opera, Gloriana, originates from a conversation about emblematic national operas, the lack thereof in the British repertory and the need for Britten to compose such an opera to coincide with the Coronation of the young Queen Elizabeth II in 1953. Britten’s insistence on composing such an opera based on the tragic love story between the first Queen Elizabeth and Essex, depicted in Lytton Strachey’s dramatic biography, raises several questions. Why should Britten, the controversial composer of several controversial works, curry royal patronage? Why should he insist on composing for an event of such national significance? Why should Britten ride the hobby horse of a national opera and share the obsession of a national opera common to German composers of the Romantic generation? Gloriana turns out to be one of the elements that point to modernist and cosmopolitan Britten’s great sense of a national identity as a composer and his claim to work within a distinctly English tradition. The Coronation opera is also one of many endeavours in Britten’s production to resuscitate English Opera, his life-long ambition. With Gloriana, Britten once more leads the fight to eradicate English people’s prejudices against musicians in general and their own composers in particular and to give the lie to the dictum that Britain is the country that has no music.

  8. Alignment of the drift tube detector at the neutrino oscillation experiment OPERA

    International Nuclear Information System (INIS)

    Goellnitz, Christoph

    2012-09-01

    The present thesis was composed during the course of the OPERA experiment, which aims to give a direct evidence for neutrino oscillations in the channel ν μ → ν τ . The OPERA detector is designed to observe the appearance of tau neutrinos in an originally pure muon neutrino beam, the CNGS beam. As important part of the detector the precision tracker (PT), a drift tube detector, consists of 9504 drift tubes in 198 modules. In this thesis, several parts of the slow control of the PT are developed and implemented to ensure operation during data taking over several years. The main part is the geometric calibration, the alignment of the detector. The alignment procedure contains both hardware and software parts, the software methods are developed and applied. Using straight particle tracks, the detector components are geometrically corrected. A special challenge for the alignment for the PT is the fact that at this kind of low-rate experiment only a small number of particle tracks is available. With software-based corrections of the module rotation, a systematic error of 0.2 mrad has been attained, for corrections of translation, a systematic error of 32 μm is reached. For the alignment between two adjacent PT walls, the statistical error is less than 8 μm. All results of the position monitoring system are considered. All developed methods are tested with Monte Carlo simulations. The detector requirements (Δp/p ≤ 0.25 below 25 GeV) are met. The analysis of the momentum measurement for high energies above 25 GeV demonstrates the resulting improvement. The mean momentum is falling significantly using the new alignment values. The significance of the detector alignment becomes most evident in the analysis of cosmic particles. The muon charge ratio R μ is expected not to be angular dependent. The χ 2 probability of the measured distribution improves up to 58%. The muon charge ratio was also investigated in dependence of particle energy in terms of the alignment

    2014-03-01

    Full Text Available For the retrieval of the vertical distribution of ozone in the atmosphere the Ozone ProfilE Retrieval Algorithm (OPERA has been further developed. The new version (1.26 of OPERA is capable of retrieving ozone profiles from UV–VIS observations of most nadir-looking satellite instruments like GOME, SCIAMACHY, OMI and GOME-2. The setup of OPERA is described and results are presented for GOME and GOME-2 observations. The retrieved ozone profiles are globally compared to ozone sondes for the years 1997 and 2008. Relative differences between GOME/GOME-2 and ozone sondes are within the limits as specified by the user requirements from the Climate Change Initiative (CCI programme of ESA (20% in the troposphere, 15% in the stratosphere. To demonstrate the performance of the algorithm under extreme circumstances, the 2009 Antarctic ozone hole season was investigated in more detail using GOME-2 ozone profiles and lidar data, which showed an unusual persistence of the vortex over the Río Gallegos observing station (51° S, 69.3° W. By applying OPERA to multiple instruments, a time series of ozone profiles from 1996 to 2013 from a single robust algorithm can be created.

    2010-01-01

    The OPERA detector at the Gran Sasso underground laboratory (LNGS) was used to measure the cosmic ray muon charge ratio Rμ = Nμ+/Nμ− in the TeV energy region. We analyzed 403069 cosmic ray muons corresponding to 113.4 days of livetime during the 2008 CNGS run. We computed separately the muon charge ratio for single and for multiple muon events in order to select different energy regions of the primary cosmic ray spectrum and to test the Rμ dependence on the primary composition. Rμ is also shown as a function of the Òvertical surface energyÓ Eμ cos !. A Þt to a simpliÞed model of muon pro- duction in atmosphere allowed the determination of the pion and kaon charge ratios weighted by the cosmic ray energy spectrum.

    A major effort is currently being pursued to validate the SAS4A LMFBR accident analysis code. Part of this effort involves SAS4A analysis of both in-pile and out-of-pile safety experiments. Such an experiment is the fifteen-pin Out-of-Pile Explusion and Reentry Apparatus (OPERA) test run at Argonne National Laboratory. This test uses a fifteen-pin triangular-shaped bundle of simulant fuel pins to demonstrate two-dimensional voiding behavior in a LMFBR subassembly during a Loss-of-Flow (LOF) accident. This experiment was chosen for SAS4A analysis both for its value in code validation and its usefulness in evaluating the limitations of the one-dimensional SAS4A sodium voiding model in accident analysis

    The commissioning and the proof of functionality of the Precision Tracker of the OPERA experiment is subject of this thesis. The timing system of the precision tracker is of major concern here. At first the time.resolution of the timing electronics was characterized additionally general running parameters were studied. Afterwards the installation and commissioning were carried out. The precision tracker is supposed to determine the momentum of throughgoing myons with an accuracy of Δp/p<0.25 as well as the sign of their charge. The commissioning is finished by now and it was shown, that the data acquisition system runs very reliable and only 1.5% show an slightly higher number of hits. The nominal spatial track resolution of σ<600 μm was also reached. (orig.)

  2. MANAGEMENT ART - The Royal Danish Opera's Artistic Director Kasper Bech Holten as case

    DEFF Research Database (Denmark)

    Nørreklit, Hanne

    This article investigates whether it would be expedient for our management models to be inspired by art as a form of consciousness. With this in mind, the article analyses the symbolic forms embedded in the management discourse practice of art in the way that the concept is unfolded by the highly...... successful Artistic Director of the Royal Danish Opera, Kasper Bech Holten. The analysis shows that conventional management models primarily use the symbolic forms of science and myth, while Kasper integrates the symbolic forms of art and science. In what Kasper has to say on management, features...... and structures for a new management discourse practice emerge which is more suited to postmodern society than more conventional management models....

    The OPERA neutrino detector at the underground Gran Sasso Laboratory (LNGS) was designed to perform the first detection of neutrino oscillations in appearance mode, through the study of nu_mu to nu_tau oscillations. The apparatus consists of a lead/emulsion-film target complemented by electronic detectors. It is placed in the high-energy, long-baseline CERN to LNGS beam (CNGS) 730 km away from the neutrino source. In August 2006 a first run with CNGS neutrinos was successfully conducted. A first sample of neutrino events was collected, statistically consistent with the integrated beam intensity. After a brief description of the beam and of the various sub-detectors, we report on the achievement of this milestone, presenting the first data and some analysis results.

    The OPERA detector at the Gran Sasso underground laboratory (LNGS) was used to measure the atmospheric muon charge ratio in the TeV energy region. We analyzed 403069 atmospheric muons corresponding to 113.4 days of livetime during the 2008 CNGS run. We computed separately the muon charge ratio for single and for multiple muon events in order to select different energy regions of the primary cosmic ray spectrum and to test the charge ratio dependence on the primary composition. The measured charge ratio values were corrected taking into account the charge-misidentification errors. Data have also been grouped in five bins of the "vertical surface energy". A fit to a simplified model of muon production in the atmosphere allowed the determination of the pion and kaon charge ratios weighted by the cosmic ray energy spectrum.

  5. Measured Early Lateral Energy Fractions in Concert Halls and Opera Houses

    BARRON, M.

    2000-04-01

    In the 30 years since early lateral reflections were first suggested as important for concert halls, spatial impression and source broadening have become almost universally accepted as essential characteristics of halls with good acoustics. Two objective measures of source broadening have been proposed. Measured values of the best defined of these measures, the early lateral energy fraction (LF), are considered here. Results from two independent measurement surveys are discussed. Comparisons of LF values by hall show a significant link between hall mean LF and hall width. There is however considerable overlap between measured LF values in different halls so the relevance of describing halls by their mean early lateral energy fraction values is questionable. The behaviour of LF values within auditoria is discussed for different concert hall plan forms and within opera houses. A measure of source broadening including sound level is proposed and results considered in the context of auditorium design.

    The OPERA experiment, designed to search for neutrino oscillations, started its physics run in July 2008. It is the most recent emulsion-counter hybrid experiment. In this experiment two different types of emulsion detectors are used. One is called Emulsion Cloud Chamber (ECC), and is used as a target. The other is called Changeable Sheet (CS), which is attached to the downstream side of each ECC to identify the ECC in which a tagged neutrino interaction occurred. The CS interfaces rough tracking information obtained in the electronic detectors to the ECC and therefore is a key element of the emulsion-counter hybrid experiment. As a first step, a CS selected by electronic detectors is scanned and analyzed to decide if the ECC is to be developed and analyzed in detail; a few CS are usually to be analyzed to identify an ECC for each tagged event due to the inaccuracy of the electronic detectors. The CS has a large scanning area and therefore Japan and Europe (Gran Sasso) are sharing in the CS analysis load to handle the scanning job. In this paper, the CS analysis method developed for the Japan scanning facility is described in detail. 100 million tracks are read out on each CS by an automatic emulsion read-out system ( S-UTS ), most of them are so-called fake tracks mainly due to low momentum Compton electrons or random noise and a few real tracks from a tagged neutrino interaction have to be picked up among a huge background. A dedicated method to reject this background without losing real tracks has been developed on the basis of analyzing track data obtained by S-UTS and combining these data with a final selection using additional information on multiple Coulomb scattering of candidate tracks obtained by human eye check to eliminate a remaining background. Performance of this method is shown to be sufficient for the OPERA experiment.

    Full Text Available This paper revisits the literature on media and gender studies in search of works that help to discuss the case of Brazilian soap operas. A series of references coming from different theoretical perspectives, with emphasis in different countries and historical periods, bring up ideas and concepts that approach the contemporary desire to connect, to participate and to interact in terms conventionally associated to the female domain. Examples from specific soap operas suggest the ways in which these prime time daily soaps blend documentary and fiction conventions and treat the Brazilian nation in melodramatic terms. In doing so, soap operas have expanded what was conventionally treated as the female domain.

    Full Text Available No mercado brasileiro, a instituição dos juros sobre capital próprio (JSCP abriu precedentes para ganhos, em operações estruturadas, oriundos da diferença entre as alíquotas tributárias das pessoas físicas e dos fundos de investimento. Tal diferença gera incentivos à realização de operações de aluguel de ações em que, às vésperas do pagamento de JSCP, os investidores pessoa física emprestam suas ações aos fundos de investimentos, os quais recebem integralmente os JSCP e repassam apenas 85% do valor aos investidores. Nosso objetivo é compreender como o excedente gerado por meio dessa operação de arbitragem tributária é dividido entre os agentes envolvidos na operação de aluguel de ações e determinar se existem condições nas quais os agentes não terão incentivos para realizar tal operação. Através de uma abordagem de jogos não cooperativos, estruturamos essa operação e analisamos possíveis equilíbrios de Nash Perfeito em Subjogos em três situações: (1 relação direta entre investidor e fundo de investimento e ausência de custos de transação; (2 relação direta entre investidor e fundo de investimento e presença de custos de transação; e (3 relação entre investidor e fundo de investimento intermediada por uma corretora, e presença de custos (menores de transação. Nos casos em que a corretora não realiza a intermediação, mais contratos tendem a ser fechados, mas o ganho do fundo apenas cobre os custos de registro da operação. Essa situação se reverte quando admitidos custos de transação elevados, em que, no caso extremo, o investidor perde seu poder de barganha e seu ganho compensa apenas sua aversão ao risco.

Four oscillated ν τ Charged Current interaction candidates have been detected in appearance mode, which are consistent with ν μ →ν τ oscillations at the atmospheric Δm 2 within the “standard” three-neutrino framework. In this paper, the OPERA ν τ appearance results are used to derive limits on the mixing parameters of a massive sterile neutrino.

    Abstract Background Depression is common in residents of Residential and Nursing homes (RNHs). It is usually undetected and often undertreated. Depression is associated with poor outcomes including increased morbidity and mortality. Exercise has potential to improve depression, and has been shown in existing trials to improve outcomes among younger and older people. Existing evidence comes from trials that are short, underpowered and not from RNH settings. The aim of the OPERA trial is to est...

    In spring 2012 CERN provided two weeks of a short bunch proton beam dedicated to the neutrino velocity measurement over a distance of 730 km. The OPERA neutrino experiment at the underground Gran Sasso Laboratory used an upgraded setup compared to the 2011 measurements, improving the measurement time accuracy. An independent timing system based on the Resistive Plate Chambers was exploited providing a time accuracy of 1 ns. Neutrino and anti-neutrino contributions were separated using the information provided by the OPERA magnetic spectrometers. The new analysis profited from the precision geodesy measurements of the neutrino baseline and of the CNGS/LNGS clock synchronization. The neutrino arrival time with respect to the one computed assuming the speed of light in vacuum is found to be δ t ν ≡ T OF c - T OF ν = (0.6±0.4 ( stat.)±3.0 ( syst.)) ns and δ {t_{overline{ν}}}equiv TO{F_c}-TO{F_{overline{ν}}}=left( {1.7± 1.4left( {stat.} right)± 3.1left( {syst.} right)} right) ns for ν μ and {{overline{ν}}_{μ }} , respectively. This corresponds to a limit on the muon neutrino velocity with respect to the speed of light of -1.8 × 10-6 OPERA result.

  1. Sleepwalking in Italian operas: a window on popular and scientific knowledge on sleep disorders in the 19th century.

    There is little knowledge on sleepwalking in ancient times even though it is a very common condition. The aim of this report is to describe the backgrounds of medical knowledge on somnambulism in the 19th century, a key period in the development of neurosciences, by analysing its representation in two famous Italian operas: La Sonnambula by Vincenzo Bellini and Macbeth by Giuseppe Verdi. The 19th-century operas may be considered as a crossing point between the popular and intellectual world because they mirror popular answers to phenomena that were still awaiting scientific explanations. Shakespeare's play Macbeth was also considered. In Shakespeare's play and in Verdi's Macbeth, sleepwalking is looked upon as a neuropsychiatric disorder, a manifestation of internal anxiety. In La Sonnambula by Bellini, this condition is considered as common disorder that anticipates scientific theories. The analysed Italian operas provide two different views on sleepwalking, probably because they are based on texts belonging to different periods. Their examination allows one to understand the gradual evolution of theories on sleepwalking, from demoniac possession to mental disorder and sleep disease. At the same time, this analysis throws some light on the history of psychological illnesses. Copyright (c) 2010 S. Karger AG, Basel.

    Neutrino oscillations are now well acknowledged, the purpose of the Opera experiment is to show how ν τ appear in a ν μ beam. The ν μ beam is produced at CERN and crosses the earth crust on a distance of 732 km before being detected in the Gran-Sasso underground laboratory. The Opera experiment uses the technique of the photographic emulsion. The detector target is a series of walls of lead bricks, each brick being made of photographic emulsions intercalated with lead sheets. A target tracker enables the localization of the brick in which the neutrino interaction has happened. As soon as the brick is found, the brick is removed from the detector and the emulsion is developed and analysed. the target tracker is made up of plastic scintillator bars on which optic fibers are stuck to collect photons and send them to photomultipliers. The main purpose of this work is the calibration of the target tracker. The first chapter introduces the standard model, the neutrino and the neutrino oscillation phenomenon. The second chapter reviews the neutrino experiments worldwide. The third chapter describes the Opera experiment while chapter 4 and 5 are dedicated to the design and operation of the target tracker. The last chapter studies through simulation the behaviour of the target tracker when submitted to an electron beam in order to use it as a complementary tool for the identification of the τ → e channel.

    Electron beam transport from E-gun to the atmospheres in EBM is determined by main parameters of beam transports such as E-gun, accelerator tube, beam optics (focusing and scanning magnets). In principle the beam transport will optimum if the electron beam travels in axial axes of accelerator tubes, and the beam optics works properly. The EBM E-gun structure of PSTA uses diode type with Pierce cathode where beam transport yield will be affected by electrode voltage of the accelerator tube. To answer above hypothesis the E-gun and accelerator tube will be simulated by making a model used accelerator software programme which is called OPERA-3D. Beam transport parameters, such as distance between cathode and anode of E-gun, accelerator electrode HV, and the symmetry of cathode Pierce E-gun with anode electrode of accelerator tube, will be investigated their impacts to direction and shape of beam transports. The simulation results shows that the three parameters affects to the direction and shape of the beam transport. Diode type of electron gun cannot result parallel electron beam, but the best beam transport of this type electron gun are obtained at the accelerator voltage 300 kV, and the distance between cathode and anode of E-gun 6.1 mm where they are in the symmetry condition.

    Full Text Available On March 17, 2011 the conductor Riccardo Muti stood in the orchestra pit at the Teatro dell’Opera di Roma and, in the presence of the Italian Prime Minister, Silvio Berlusconi, and the Italian President, Giorgio Napolitano, denounced the Italian government’s cuts to funding for the arts and culture. He then invited the entire audience to join the opera’s chorus in an encore of Va’ Pensiero, the hymn of the Hebrew slaves in Nabucco, to protest the cuts. Within two days of the sing-a-long, the Italian government reversed the course it set more than ten months before and agreed to a tax that would be used to restore funds to the arts and culture budget. This article traces how and why these acts of protest in Italy developed, succeeded, and then were appropriated by transnational activists interested in encouraging popular constitutionalism. Because the entire process made considerable use of Facebook, blogs, YouTube, and Twitter, this case study simultaneously explores how a popular protest became a successful expression of popular constitutionalism, and considers how the messages of that protest evolved across a transnational public sphere that encompassed Web 2.0.

    Redesign of analyzer magnet on ion implanter using superfish and opera-3D simulator has been done. In order for the implanted ions on a target is a single ion a magnetic analyzer is needed. The magnetic analyzer can separate some impurity ions from accelerated ion beams to produce a single ion beams. Ion implanter in PTAPB has been equipped with a magnetic analyzer, but the design details data were not available and the functions still were not optimal so that it will hamper for maintenance and development. The purpose of this activity is to obtain a document containing technical information and to optimize a magnetic analyzer design. To achieve these objectives, the activities initiated by searching for references related to the magnetic analyzer, perform detailed calculation with considering the existing parameters, simulation of the design that has been made, determination of design parameters and optimization of the designs. From this activity can be obtained a detailed design document of magnetic analyzer for 150 keV particle energy with 60° bending angle and the ability to separate particles with m / z = 8 amu. While the optimization of the previous design can be done by changing the shape of C-type magnetic core into H type, change the shape of the magnetic pole into a square with the position of incoming beam makes a positive θ angle and inclined to the edge of the magnetic poles.

    The gas system of the drift tube detector of the neutrino experiment OPERA is presented. The drift tube detector, called precision tracker (PT), consists of 10 000 thinwalled aluminum tubes of 38 mm diameter and 8 m length filled with an 80% Ar 20% CO2 gas mixture. The total gas volume amounts to 80 m3. During stable operation the gas is exchanged once per 80 h and not recycled. Thus about 1 m 3 per hour is consumed. Argon and CO2 are stored and supplied in liquid form. Subsequently they are mixed and the composition ratio is regulated with a precision better than 1% per component. Inside the drift tubes the gas is kept at a constant absolute pressure within ±0.5%. Since the experiment is operated in the low activity environment of the Gran Sasso underground laboratory, monitoring of the gas quality with a radioactive source is prohibited. Instead the oxygen content of the used gas is measured. We report on the first experience with the performance of the gas system.

    The SAS4A accident analysis code is a tool for evaluating consequences of accidents in Liquid Metal Fast Breeder Reactors (LMFBR). It incorporates models for describing coolant voiding, fuel pin swelling and disruption, cladding motion, heat transfer, and reactivity feedback. As part of the code verification effort, SAS4A is used to analyze both in-pile and out-of-pile safety experiments. Such an experiment is the fifteen-pin Out-of-Pile Expulsion and Reentry Apparatus (OPERA) test run at Argonne National Laboratory. This test uses a fifteen-pin triangular-shaped bundle of simulant fuel pins to demonstrate two-dimensional voiding behavior in a LMFBR subassembly during a Loss-of-Flow (LOF) accident. The experiment has been analyzed using SAS4A for two reasons; further code validation, and evaluation of the limitations of the one-dimensional SAS4A sodium voiding model in accident analysis. A comparison of experimental data and code results shows that the SAS4A model follows the experiment quite well during times when the experiment is behaving in a one-dimensional fashion (prior to start of voiding and after full radial voiding has been established). The code does not do as well during the period right after voiding initiation when the void is propagating radially and, to a lesser extent, axially

    Music is one of the most sophisticated and fascinating functions of the brain. Yet, how music is instantiated within the brain is not fully characterized. Singing is a peculiar aspect of music, in which both musical and linguistic skills are required to provide a merged vocal output. Identifying the neural correlates of this process is relevant for both clinical and research purposes. An adult white man with a presumed left temporal glioma was studied. He is a professional opera singer. A tailored music evaluation, the Montreal Battery of Evaluation of Amusia, was performed preoperatively and postoperatively, with long-term follow-up. Intraoperative stimulation mapping (ISM) with awake surgery with a specific music evaluation battery was used to identify and preserve the cortical and subcortical structures subserving music, along with standard motor-sensory and language mapping. A total resection of a grade I glioma was achieved. The Montreal Battery of Evaluation of Amusia reported an improvement in musical scores after the surgery. ISM consistently elicited several types of errors in the superior temporal gyrus and, to a lesser extent, in the inferior frontal operculum. Most errors occurred during score reading; fewer errors were elicited during the assessment of rhythm. No spontaneous errors were recorded. These areas did not overlap with eloquent sites for counting or naming. ISM and a tailored music battery enabled better characterization of a specific network within the brain subserving score reading independently from speech with long-term clinical impact.

These possible benefits are discussed along with an overview of the range of skills and requirements which a career in opera is likely to demand. The paper includes as case-history a recent example of this collaborative approach - The Paris Collection, a large-scale opera project which was performed in January 2014 at the National Concert Hall in Dublin by students from Dublin Institute of Technology Conservatory of Music and Drama and designed by students from Dublin College of Creative Arts. The production was named thus because the two operas featured, Lehar's The Merry Widow and Puccini's La Bohème are both set in Paris. The project was implemented through the undergraduate and postgraduate modular frameworks in each college and involved the engagement of over 160 students. The production, which was positively received and subsequently won the Institute for Designers in Ireland Highly Commended Award in the Education category, was deemed to be a success; an appraisal which was expressed not only in the positive response to the performance, but also through feed-back and evaluation from staff and students in various formal and informal de-briefing sessions.

    Full Text Available Abstract Background Objective acoustic analysis is a key component of multidimensional voice assessment. OperaVOX is an iOS app which has been shown to be comparable to Multi Dimensional Voice Program for most principal measures of vocal function. As a relatively cheap, portable and easily accessible form of acoustic analysis, OperaVOX may be more clinically useful than laboratory-based software in many situations. This study aims to determine whether correlation exists between acoustic measurements obtained using OperaVOX, and perceptual evaluation of voice. Methods Forty-four voices from the multidisciplinary voice clinic were examined. Each voice was assessed blindly by a single experienced voice therapist using the GRBAS scale, and analysed using OperaVOX. The Spearman rank correlation co-efficient was calculated between each element of the GRBAS scale and acoustic measurements obtained by OperaVOX. Results Significant correlations were identified between GRBAS scores and OperaVOX parameters. Grade correlated significantly with jitter (ρ = 0.495, p < 0.05, shimmer (ρ = 0.385, p < 0.05, noise-to-harmonic ratio (NHR; ρ = 0.526, p < 0.05 and maximum phonation time (MPT; ρ = −0.415, p < 0.05. Roughness did not correlate with any of the measured variables. Breathiness correlated significantly with jitter (ρ = 0.342, p < 0.05, NHR (ρ = 0.344, p < 0.05 and MPT (ρ = −0.336, p < 0.05. Aesthenia correlated with NHR (ρ = 0.413, p < 0.05 and MPT (ρ = −0.399, p < 0.05. Strain correlated with Jitter (ρ = 0.560, p < 0.05, NHR (ρ = 0.600, p < 0.05 and MPT (ρ = −0.356, p < 0.05. Conclusions OperaVOX provides objective acoustic analysis which has shown statistically significant correlation to perceptual evaluation using the GRBAS scale.

    Full Text Available Ao longo dos últimos quarenta anos, as telenovelas - seriados comerciais exibidos seis vezes por semana em horário nobre, feitos para um público imaginado como feminino, mas assistidos por um público composto, em sua fase mais popular, em 40% por homens - se tornaram espaço privilegiado de interpretação do Brasil. Uma complexa rede de relações envolve a agenda militar autoritária nacionalista e desenvolvimentista; a agenda de anunciantes, homens da indústria e do comércio; e o talento de escritores, atores e diretores de esquerda (também nacional e desenvolvimentista com repertório e conhecimento de cinema e teatro. Feita ao mesmo tempo em que vai ao ar, a novela captou e expressou ao menos três interpretações de um país que se transformou rápida e estruturalmente. As principais convenções estéticas do gênero alimentaram emissoras rivais a propor três interpretações do país. Em sintonia com o Brasil que se quer do futuro, as novelas da Rede Globo, a partir de 1969, registraram os dramas da urbanização, das diferenças sociais, da fragmentação da família, da liberalização das relações conjugais e dos padrões de consumo.

    In last decades, air pollution modelling assumed a key role for the definition and evaluation of suitable emission control strategies, supporting Regional Decision Makers in the design of long-term plans for air quality improvement. This is a complex task, due to the non-linear chemical reactions and physical processes that bring to secondary pollution formation and accumulation, involving precursor emissions, namely VOC, NOx, NH3, primary PM and SO2. The problem is even more complex when constraining policy to a fixed budget. This paper presents the first results of the OPERA (Operational Procedure for Emission Reduction Assessment) LIFE+ project (2010-2013, www.operatool.eu) aiming to design and to implement an enhanced approach to identify efficient regional policies (1) complying with National and EU air quality standards, (2) with local emission and meteorological features, financial, technological and social constraints and (3) considering potential synergies with actions to reduce GHG emissions. The proposed methodology is based on a multi-objective (air quality, internal and external costs) optimization problem. The decision variables are the technical and non-technical emission abatement measures. Artificial neural networks, identified processing long-term 3D deterministic multi-phase modelling system simulation outputs, describe the nonlinear relations between the control variables (precursor emissions reduction) and the air quality indexes (AQIs), defining the air quality objective. The internal costs are due to emission reduction measures implementation, while the external costs assess the damage due to population pollution exposure. The methodology has been implemented in a software tool (RIAT+) and tested on two regional applications, Emilia Romagna (IT) and Alsace (FR).

    Full Text Available Abstract Background Interactions between the immune response and brain functions such as olfactory, auditory, and visual sensations are likely. This study investigated the effect of sounds on alloimmune responses in a murine model of cardiac allograft transplantation. Methods Naïve CBA mice (H2k underwent transplantation of a C57BL/6 (B6, H2b heart and were exposed to one of three types of music--opera (La Traviata, classical (Mozart, and New Age (Enya--or one of six different single sound frequencies, for 7 days. Additionally, we prepared two groups of CBA recipients with tympanic membrane perforation exposed to opera for 7 days and CBA recipients exposed to opera for 7 days before transplantation (pre-treatment. An adoptive transfer study was performed to determine whether regulatory cells were generated in allograft recipients. Immunohistochemical, cell-proliferation, cytokine, and flow cytometry assessments were also performed. Results CBA recipients of a B6 cardiac graft that were exposed to opera music and Mozart had significantly prolonged allograft survival (median survival times [MSTs], 26.5 and 20 days, respectively, whereas those exposed to a single sound frequency (100, 500, 1000, 5000, 10,000, or 20,000 Hz or Enya did not (MSTs, 7.5, 8, 9, 8, 7.5, 8.5 and 11 days, respectively.

Adoptive transfer of whole splenocytes, CD4+ cells, or CD4+CD25+ cells from opera-exposed primary allograft recipients resulted in significantly prolonged allograft survival in naive secondary recipients (MSTs, 36, 68, and > 100 days, respectively. Proliferation of splenocytes, interleukin (IL-2 and interferon (IFN-γ production was suppressed in opera-exposed mice, and production of IL-4 and IL-10 from opera-exposed transplant recipients increased

  17. Neutrino interaction event reconstruction and analysis in the Opera emulsion targets and charmed background rejection in the τ → 3h channel

    Besnier, M.

    2008-07-01

    OPERA (Gran-Sasso, Italy) is a long-baseline neutrino experiment dedicated to the tau neutrino detection in a pure muon neutrino beam, produced at CERN (730 km away). The main goal is to observe the ν μ → ν τ oscillation. The experiment uses a hybrid technology with electronic detectors and target blocks made of lead plates interleaved with nuclear emulsion sheets, in order to sign efficiently the ν τ interactions. The fundamental features of OPERA are its particle reconstruction performances achieved in spatial and angular resolutions. The first studies done in this thesis concern the development of several analysis tools like the particle momentum determination using the multiple coulomb scattering in target, and a method of neutrino interaction reconstruction for multi-vertex events. Then it has been possible to develop a multivariable analysis in order to separate τ and charmed events in the τ decay channel into three charged hadrons. These tools have been tested with neutrino interactions observed first with the OPERA test-beam called PEANUT, then with the OPERA events accumulated during the first CNGS (CERN Neutrino to Gran Sasso) run in 2007. The combined analysis of these events has shown that both the analysis method and the OPERA detector behaviour are well understood. (author)

    Following Super Kamiokande and K2K experiments, Opera (Oscillation Project with Emulsion tracking Apparatus), aims to confirm neutrino oscillation in the atmospheric sector. Taking advantage of a technique already employed in Chorus and in Donut, the Emulsion Cloud Chamber (ECC), Opera will be able to observe the {nu}{sub {mu}} {yields} {nu}{sub {tau}} oscillation, through the {nu}{sub {tau}} appearance in a pure {nu}{sub {mu}} beam. The Opera experiment, with its {approx} 100000 m{sup 2} of nuclear emulsions, needs a very fast automatic scanning system. Optical and mechanics components have been customized in order to achieve a speed of about 20 cm{sup 2}/hour per emulsion layer (44 {mu}m thick), while keeping a sub-micro-metric resolution. The first part of this thesis was dedicated to the optimization of 4 scanning systems at the French scanning station, based in Lyon. An experimental study on a dry objective scanning system has also been realized. The obtained results show that the performances of dry scanning are similar with respect to the traditional oil scanning, so that it can be successfully used for Opera. The second part of this work was devoted to the study of the neutrino interaction location and reconstruction strategy actually used in Opera. A dedicated test beam was performed at CERN in order to simulate Opera conditions. The obtained results definitely confirm that the proposed strategy is well adapted for tau search. (author)

Os hotéis são prestadores de serviços turísticos que causam significativos impactos ambientais, modificando os espaços socioambientais. O presente artigo, oriundo de pesquisa qualitativa, com característica exploratória e descritiva, tem como objetivo principal identificar, por meio de pesquisa bibliográfica e das iniciativas de mercado, se os operadores hoteleiros brasileiros vêm adotando práticas de gestão ambiental em seus negócios, bem como sistemas de gestão ambiental certificáveis. A pesquisa tenciona ainda destacar os principais benefícios que os programas de Gestão Ambiental oferecem à operação hoteleira no país. Conclui-se que nos empreendimentos hoteleiros brasileiros há pouca adesão a programas de Gestão Ambiental e dentre seus gestores poucos têm a questão ambiental como oportunidade de mercado ou como um elemento obrigatório nas agendas administrativa e operacional, na promoção da longevidade e sucesso da organização.Environmental Management Systems in Hotel Operation - The tourism is one of the most important economic sectors in the country.

    Full Text Available OBJETIVO: Apesar de serem bem estabelecidas as alterações esplênicas nas dislipidemias, como a doença de Gaucher, ainda não se estudou adequadamente a relação do baço com o metabolismo lipídico. Com vista a contribuir para preencher esse hiato, a presente investigação avaliou experimentalmente o lipidograma na presença do baço, em asplenia e após operações conservadoras desse órgão. MÉTODOS: Foram utilizadas 50 ratas Wistar de pesos e idades semelhantes distribuídas em quatro grupos: Grupo 1- controle, com baço íntegro; Grupo 2 - laparotomia e laparorrafia, Grupo 3 - esplenectomia total; Grupo 4 - esplenectomia subtotal e Grupo 5 - esplenectomia total complementada por implantes de tecido esplênico autógeno. Após quatro meses, foram dosados os níveis séricos de triglicérides, colesterol total e suas frações VLDL, LDL, HDL. Os resultados dos quatro grupos foram comparados entre si pela análise de variância, seguida pelo teste de Tukey-Kramer, com significância para p < 0,05. RESULTADOS: Não houve diferença entre os grupos 1, 2, 3 e 4. Nos animais submetidos a esplenectomia total, as concentrações de colesterol total (p = 0,0151 e de sua fração LDL (p < 0,0001 foram maiores, enquanto a fração HDL foi menor (p = 0,0026 do que as encontradas nos demais grupos. Não houve diferença entre os grupos com relação aos triglicérides (p = 0,1571 e VLDL (p = 0,2527. CONCLUSÕES: É provável que o baço desempenhe um papel de destaque no metabolismo lipídico de ratas e que a esplenectomia total se relacione com alterações no controle do colesterol. É possível que a preservação de tecido esplênico previna tais distúrbios metabólicos.

    2008-02-01

    Full Text Available Over two days in October 2005, police in Mexico City conducted a series of raids on male-to-female transgender (travesti prostitutes working in the streets. The motive of the investigation was not related to sex work at all, but rather, the hunt for a serial killer responsible for the deaths of elderly women between 2003 and 2005. With few leads apart from reports by a couple of eyewitnesses that they had seen ‘a man dressed as a woman’ enter the houses of the victims, the Chief Public Prosecutor announced that the killer could be a travesti. On January 25, 2006, the ‘lady-killer’ was finally discovered to be neither a ‘man dressed as a woman’, nor a travesti. The suspect, a female former lucha libre wrestler, Juana Barraza, was taken into custody. In the period leading up to the October raids, Mexico’s chief television channel, Televisa, finished up the season of its popular soap, La Madrastra, with a plot line that features a man who dresses as a woman to disguise his usual male identity and kill his female victims. This paper examines the case, looking at the influence of the soap opera narrative in the profiling of travestis as suspect ‘men dressed as women’. It draws on studies of soap opera and mass media forms in Mexican society, as well as the work of transgender theory in understanding how crossgender identities are circumscribed by discourse.

    The authors draw on (1) the hierarchy-of-effects (HOE) model, (2) the stages-of-change (SOC) model, (3) social learning theory (SLT), and (4) the diffusion of innovations (DOI) to synthesize a staged model through which communication messages have effects on individual behavior change by stimulating (1) involvement with media characters and role modeling of their actions, and (2) interpersonal communication. Data from a field experiment in Tanzania on the effects of an entertainment-education radio soap opera, Twende na Wakati (Let's Go With the Times), on the adoption of family planning, are analyzed in light of a six-staged model of communication effects. It is found that (1) the model provides a useful framework for understanding the effects of an entertainment-education program, and (2) the radio soap opera promoted progress through the stages for family planning adoption in the treatment area in three of the four years of broadcast, and in the comparison area after broadcasts of the radio program began there.

    2017-12-01

    Full Text Available Shakespeare thrives not only in the theatre, but also through what Bolter and Grusin call remediation. This article analyses how opera and musical reread Elizabethan drama shifting from spoken to sung discourse and travelling transnationally, temporally and across genres. Its main approach is comparative and relies on the history of mentalities. Rereading is dictated by cultural context, the conventions of the lyrical theatre, social and political factors and reception. Gender is reread in Bellini‘s I Capuleti e i Montecchi and in Britten‘s A Midsummer Night‟s Dream, and religion - in Gounod‘s Roméo et Juliette and Bernstein‘s West Side Story. Cultural and historical barriers enjoin recontextualisation: the English, French and Welsh verbal fun in The Merry Wives is metamorphosed into Germ-Italian in Salieri‘s Vienna, while prayer is bowdlerised in Bentoiu‘s Hamlet written in communist Romania. Porter‘s Kiss Me, Kate rewrites The Taming of the Shrew in a post-modern musical avant la lettre featuring the cast of a theatre company on- and off-stage. However, operas such as Rossini‘s Otello or Thomas‘s Hamlet are shown to have almost replaced Shakespeare‘s initial message. The article emphasises the idea that operations of rereading and rewriting, in a musical context, significantly enrich the ample panoply of Shakespearean adaptations.

    Full Text Available Tendo em vista as mudanças na sociedade moderna, decorrentes especialmente das novas tecnologias de informação e comunicação (TIC`s, e a intensificação do processo de globalização, as organizações têm buscado atualizar suas tecnologias, processos e ferramentas de trabalho, garantindo competitividade e posição favorável no mercado atuante. Neste contexto, uma das estratégias utilizadas é a terceirização das atividades que não são inerentes ao objetivo final da organização, dentre as quais se caracterizam os serviços logísticos. No Brasil, anualmente, são gastos cerca de R$ 192 bilhões, ou 11,7% do Produto Interno Bruto Nacional, com logística. Deste montante, aproximadamente 63% são direcionados para pagamento de terceiros, ou seja, para os prestadores de serviços logísticos. Considerando-se esta representatividade do setor para a economia nacional, o presente trabalho teve como objetivo demonstrar os motivos que conduzem as empresas a optarem pela terceirização dos serviços de distribuição logística, segundo a visão de um coordenador de operações logísticas. Para tanto, foi realizada uma pesquisa qualitativa básica a partir de entrevista, com a utilização de um roteiro semiestruturadojunto ao coordenador de operações logística da AGV Logística, responsável pelas operações da empresa aqui denominada Betha. Segundo o entrevistado, a empresa Betha opta em terceirizar seus serviços logísticos visando redução nos custos de contratação e manutenção predial, desenvolvimento e manutenção de mão de obra qualificada, investimento em tecnologia de informação e em equipamentos de movimentação. Além dos custos, outras razões para a terceirização são o maior foco no negócio e a flexibilidade operacional.

    2005-01-01

    A neural-network (NN) approach for neutrino interaction vertex reconstruction in the OPERA experiment with the help of the Target Tracker (TT) detector is described. A feed-forward NN with the standard back propagation option is used. The energy functional minimization of the network is performed by the method of conjugate gradients. Data preprocessing by means of cellular automaton algorithm is performed. The Hough transform is applied for muon track determination and the robust fitting method is used for shower axis reconstruction. A comparison of the proposed approach with earlier studies, based on the use of the neural network package SNNS, shows their similar performance. The further development of the approach is underway

    2016-04-01

    Full Text Available This article wants to argue that the two theatrical shows, Sonno from the Italian company OPERA, and Le Grand Architecte, from the French company Pseudonymo, are model examples of the return to a certain kind of narrative dimension in the contemporary theatre. Over the past years, theatrical theory has often maintained that narrative drama has been completely replaced by visual dramaturgy in contemporary theater. However, an analysis of these two shows suggests that their visual dramaturgy, their construction of sounds and lights, as well as the performer’s actions want to evoke in spectators clear narrative associations. I will set out by presenting the state of the art and the artistic process of the two companies, to then focus on the way in which these two shows produce a wealth of narrative associations in the audience.

  18. Music performance anxiety and occupational stress amongst opera chorus artists and their relationship with state and trait anxiety and perfectionism.

    Science.gov (United States)

    Kenny, Dianna T; Davis, Pamela; Oates, Jenni

    2004-01-01

    This study explored the inter-relationships among state and trait anxiety, occupational stress, perfectionism, aspiration, and music performance anxiety in a group of elite operatic chorus artists employed full-time by a national opera company. The chorus artists reported higher trait anxiety, higher occupational role concerns, and higher occupational personal strain than normative samples. Higher scores on personal resources were associated with the higher scores on trait anxiety. It appears that these resources were used adaptively to manage anxiety. High trait anxiety was also associated with high personal strain in the work environment. Anxiety was not related to occupational roles or issues related to the physical environment or working conditions. These results suggest that while trait anxiety and music performance anxiety were closely associated, occupational stress makes a separate contribution to the quality of working life experienced by elite choral artists.

    TheOPERAexperiment, designed to perform the first observation of ν{sub μ} → ν{sub τ} oscillations in appearance mode through the detection of the τ leptons produced in ν{sub τ} charged current interactions, has collected data from 2008 to 2012. In the present paper, the procedure developed to detect τ particle decays, occurring over distances of the order of 1mm from the neutrino interaction point, is described in detail and applied to the search for charmed hadrons, showing similar decay topologies as the τ lepton. In the analysed sample, 50 charm decay candidate events are observed while 54 ± 4 are expected, proving that the detector performance and the analysis chain applied to neutrino events are well reproduced by the OPERA simulation and thus validating the methods for ν{sub τ} appearance detection.

    During the eighteenth century, several towns located in what is known today as the Suisse romande were extremely receptive toward scientific culture, and most notably Newtonianism. In this paper I deal with a nine-volume publication of Newton's Opera Omnia that was planned in Geneva and Lausanne during the late 1730s and 1740s. This publication has not received the attention it deserves. To the best of my knowledge, even an awareness of its existence is lacking in the literature devoted to the reception of Newtonianism. This paper examines the circumstances of the publication of a complete set of all of Newton's works known at the time, and the motivations of the editors, mathematicians, and publishers who were involved in this editorial enterprise.

    Very highly efficient filters containing a porous glass fibre fabric are used in industrial installations to trap radioactive or toxic particles in order to limit their release, notably in accidental situations. Thus this set of articles discusses various issues related to the use of such filters. A first one describes how air radioactivity is continuously monitored by two coexisting networks: Opera-Air and Teleray. It indicates where air radioactivity comes from, and how the origin of a release can be determined, and outlines the importance of modelling tools. Air monitoring about the Gravelines nuclear power plant is briefly presented with a drawing. A second article comments the existence of numerous tools which are used as information channels about the monitoring of air radioactivity: web sites, mobile application, and so on. The last article briefly describes the journey of a filter from its removal on a Monday to a complete and validated analysis which lasts between two and four weeks

The huge number of channels, the inaccessibility of many parts of the detector and the wide uncertainty about the signal amplitude pushed to study a low cost, high sensitivity discriminator, and a very carefully designed layout for the read out system. Here we will present a novel application of LVDS line receiver as discriminator, showing that it exceeds the requirements of a large RPC based detector and offers the intrinsic advantages of a mature technology in terms of costs, reliability and integration scale. We will also present the layout of the read out system showing as the sensitivity and the noise immunity were preserved in a system where the front end electronics is far away from the detector.

    The considerable voice timbre differences between musical theater (MT) and western operatic singers are analyzed with respect to voice source and formant frequencies in five representatives of each singer group. Audio, subglottal pressure (P(sub)), and electroglottograph (EGG) signals were recorded while the subjects sang a sequence of [pae:] syllables starting at maximal vocal loudness and then gradually decreasing vocal loudness. The task was performed at each of two fundamental frequencies (F(0)), approximately one octave apart. Ten equally spaced P(sub) values were then selected for each F(0). The subsequent vowels were analyzed in terms of flow glottograms derived by inverse filtering the audio signal, which also yielded formant frequency data. Period time (T(0)), peak-to-peak pulse amplitude (U(p-t-p)), and maximum flow declination rate (MFDR) were measured from the flow glottograms while closed quotient Q(closed) (T(cl)/T(0)) was determined in combination with the differentiated EGG signal. Also the relationship between the first and the second harmonic in the spectrum (H(1)-H(2)), the amplitude quotient (AQ), that is, the ratio between U(p-t-p) and MFDR, and normalized AQ, that is, AQ normalized with respect to period time was calculated as well as the sound pressure level. The results showed that both the MT and the opera singers varied their P(sub) systematically, approximately doubling P(sub) for a doubling of F(0). For a given value of P(sub), the MT singers produced higher values of MFDR, U(p-t-p), and Q(closed), and lower values of H(1)-H(2), indicating a weaker fundamental. Further, the MT singers showed higher formant frequencies and did not show the opera singers' characteristic clustering of F(3), F(4), and F(5).

    Directory of Open Access Journals (Sweden)

    Milanović Biljana

    2012-01-01

    Full Text Available Part of the history of the National Theatre in Belgrade in the decade before the First World War relates to processes of discontinuity in the professionalization and modernization of the musical section in this institution and its repertoire. It had to do with abrupt changes reflected in three short-lived phases: improvements in musical ensemble and opera performances (1906-1909, the annulment of these efforts and results with a return to the old repertoire, and then again a new beginning once more with a fresh attempt to establish the Opera (1913-14. These dynamics were affected by the social and political context. It was dependent on frequent changes of the Theatre’s management staff whose main representatives had mutually conflicting views on important questions concerning the functioning of their institution. Relations between them were strongly marked by contested political motives. Theatre managers were appointed by ministers of education who could also be relieved of their posts, and members of the management staff were always active in political parties. These facts acted as a decisive factor in their communication which was similar to the behaviour and customs of public political life where an opponent is seen as an enemy, not as a partner in solving common problems. Critical and polemical discourses on important aspects of organization and programme strategy of the Theatre were burdened by political rivalry which also found its place in discussions on the cultivation of music. Questions relating to music were considered in a declarative way, so that music was instrumentalized as a means of political empowerment. The facts about music in the National Theatre raise many issues related to aspects of modernization, national identification, transfers of „high“ and popular musical cultures as well as to other problems of social, historical and cultural contexts that were intertwined in the operation of the Theatre.

    International Nuclear Information System (INIS)

    Tran, N.T.

    2010-10-01

    Neutrino oscillations, based on a change of flavor state of a neutrino during its propagation, can explain the deficits observed on solar and atmospheric neutrinos and provide some interesting indications for physics beyond the Standard Model by studying the mixing angles and the hierarchy of neutrino mass. The OPERA experiment is the first experiment designed to observe the appearance of a ν τ by the oscillation of the ν μ to ν τ in the CNGS beam from CERN to Gran Sasso. OPERA is a hybrid detector combining both the technique of an on time electronic detection and the technique of emulsion cloud chamber (ECC). The ECC detector is a passive detector (target) of 150.000 bricks, each one consisting of sheets of lead, used as target, alternating with nuclear photographic emulsions whose accuracy of track reconstruction is about one micron. The detector also includes two spectrometers with magnetized iron plates 5 cm thick alternating with RPC (resistive plate chamber) associated with six sets of drift tubes for the measurement of the charge and momentum of the muon. It includes also a Veto plane used for rejection of particles coming outside the target. This detector simultaneously allows a high spatial resolution and a large target mass which are two very conditions necessary for collecting charged current neutrino interactions from oscillated ν τ and observing the decay topology of τ. This thesis presents a study on tau decay in the muonic channel. It has contributed to 1) the development of an algorithm for the selection of the neutrino interactions in the target, 2) the studies on the muon identification in electronic detectors and the connection of its trace with those reconstructed in the emulsions, which represent a fundamental point both for the tau signal identification as the rejection of charmed background, 3) the development of a neural network to discriminate the signal from the charmed background regardless of the muon identification in

    Full Text Available Petar Konjović (Čurug, May 5, 1883 - Belgrade, October 1, 1970 stands out among Serbian composers as an author of instrumental and vocal compositions. Studies at the Prague Conservatory (1904-1906 acquainted Konjović with Czech music, Wagner's opus, and the Russian national-romantic school, which contributed to the evolution of his talent for both music and stage, enabling him to express his ideas more explicitly in operatic works. It was in the Prague that the second opera - Prince of Zeta - was conceived, with new musical vividness and dramatic appeal (first version composed 1906-1926, the second and final 1929-1939, followed by Koštana (1928, Peasants (1951 and Fatherland (1960. Konjović's mature operas are characterized by his masterful handling of form, both in close-ups and in detail, as well as his deeply individual assimilation of musical folklore into his work. The Prince of Zeta is not to be understood as a folk opera, but some main themes are directly derived from folk music, precisely from the Montenegrin folk songs quoted in the Mokranjac's Ninth Garland and treated in Konjović's post-romantic, almost expressionistic way, interwoven with some Italianate leitmotifs, so as to present the opera's two worlds, Montenegrin and Venetian. In the process of forming Konjović's operatic style, with vocal parts based mainly on the principle of declamation, the opera Prince of Zeta (first performed in Belgrade, 1929, conducted by Lovro von Matačić proved to be a work of great impact. Hardly anyone grasped then the wide sweep of inspiration which allowed the composer to set and to solve several important problems connected with music drama, essential also in his subsequent stage works. First of all, Konjović had to handle in his own way the verbal drama the prototype of his opera, Maxim Crnojević by the Serbian poet Laza Kostić (1841-1910. Permission came from the playwright in the first decade of the 1900, Prince of Zeta being partly

    Brugière, Timothée

    OPERA (" Oscillation Project with Emulsion-tRacking Apparatus ") is a neutrino beam experiment located in hall C of the Gran Sasso underground laboratory (LNGS), in Italia, under a equivalent of 3.8 km water (corresponding to a cut at 1.5 TeV for the muons). The first purpose of OPERA is the direct observation of the νμ ➝ ντ oscillation in the atmospheric sector observing an ντ appearance 730 km away from the target in a quasi pure νμ beam (CNGS). OPERA is an hybrid detector with an instrumented target part (~125 000 bricks made with emulsion and lead sheets) and a spectrometer. The data taking have started in 2006 and 55 000 events have been registred. The first ντ candidate have been observed this year. The work done during this thesis is oriented around three main topics : Define the trigger rules of the target tracker acquisition system for beam neutrino events, synchronise target tracker and RPC elements, implement the results inside the simulation and the study of the feasibility of an atmos...

    The OPERA detector, designed to search for ν{sub μ} → ν{sub τ} oscillations in the CNGS beam, is located in the underground Gran Sasso laboratory, a privileged location to study TeV-scale cosmic rays. For the analysis here presented, the detector was used to measure the atmospheric muon charge ratio in the TeV region. OPERA collected charge separated cosmic ray data between 2008 and 2012. More than 3 million atmospheric muon events were detected and reconstructed, among which about 110000 multiple muon bundles. The charge ratio R{sub μ} ≡ N{sub μ+}/N{sub μ-} was measured separately for single and for multiple muon events. The analysis exploited the inversion of the magnet polarity which was performed on purpose during the 2012 Run. The combination of the two data sets with opposite magnet polarities allowed minimizing systematic uncertainties and reaching an accurate determination of the muon charge ratio. Data were fitted to obtain relevant parameters on the composition of primary cosmic rays and the associated kaon production in the forward fragmentation region. In the surface energy range 1-20 TeV investigated by OPERA, R{sub μ} is well described by a parametric model including only pion and kaon contributions to the muon flux, showing no significant contribution of the prompt component. The energy independence supports the validity of Feynman scaling in the fragmentation region up to 200 TeV/nucleon primary energy. (orig.)

    Full Text Available In this article, we describe part of an action research project carried out during a classroom-based art course at a higher education institution. We gave the students themed collaborative drawing assignments, with the purpose of achieving a rich picture of what they associated with the notion of “going to the opera”. They completed assignments before and after attending a guided tour and a ballet performance at a famous opera house. We aimed to address two main research questions: a How can the students’ understanding of opera and ballet develop through their experience of a ballet performance? and b How can drawing activities in the classroom support collaborative learning and the students’ personal development? The data gathered involved three main elements: 1 the rich pictures themselves, 2 the teachers’ observations of the students and 3 the students’ reflections on the process. The study points towards a significant transformation of the students’ representation of the concept of opera, as illustrated in their drawings. We discuss how the students’ drawings may reflect their development in terms of attitude and their newly acquired knowledge of an artistic genre they knew little about, and suggest new avenues for further research.

    Full Text Available Il saggio considera l'esperienza politica degli intellettuali cinesi e americani in Chinese Opera (1998, romanzo breve dello scrittore americano di discendenza cinese Alex Kuo. Il suo protagonista, compiendo un viaggio dagli Stati Uniti alla Cina nei mesi immediatamente precedenti alle dimostrazioni di piazza Tiananmen, intraprende un cammino alla ricerca della sua storia familiare, e delle ragioni che hanno spinto il padre all'esilio. Intellettuale e musicista, a cavallo tra due realtà di attivismo politico che hanno esercitato il loro peso nel definire o nello smantellare, a seconda delle prospettive, proprio i concetti di appartenenza, il protagonista sceglie e fa proprio l'impegno sul piano transnazionale, ma a partire da una consolidata quanto rivendicata consapevolezza della propria individualità. La letteratura e l'arte sono il punto focale in grado di esprimere una tensione tra l'individuo e la collettività che ritorna con una declinazione diversa in entrambi i sistemi socio-politici. Il romanzo, dunque, propone un soggetto politicizzato ma non contenibile all'interno di alcuna coordinata discorsiva pre-scritta. A sua volta, il discorso politico nel testo letterario, costruito nel senso della double critique di Khatibi, intreccia la dimensione pubblica e privata dell'intellettuale con le significazioni etniche, nazionali e transnazionali.

  5. Timing calibration of the trigger system for the drift tube detector of the OPERA neutrino oscillation experiment

    International Nuclear Information System (INIS)

    Lenkeit, Jan

    2015-11-01

    The OPERA experiment searches for ν μ → ν τ oscillations in an almost pure ν μ beam. The goal is to observe the oscillations in appearance mode by using a large-scale lead/emulsion target to resolve individual ν τ interactions. Magnetic spectrometers measure the charge and momentum of beam induced muons leaving the target sections. The Precision Tracker, a drift tube detector consisting of almost 10000 drift tubes, provides the tracking information inside the spectrometers. The coordinate measurement in the drift tubes is derived from a time measurement relative to an external trigger signal. In order to reach the required momentum resolution of less than 25 % for particle momenta up to 25 GeV, the uncertainty on the trigger timing must not exceed a value of 5 ns. In this thesis, a procedure for the timing calibration of the trigger system is presented. A step-by-step calibration of the corresponding signal paths is described. Applying all calibration results, a spatial resolution of 255 μm is achieved for the Precision Tracker, meeting the specified requirements. Furthermore, a method using the calibrated trigger system for performing time of flight measurements with atmospheric muons is developed. The average error on the measured flight times is ±4.5 ns.

    The National Spherical Torus Experiment (NSTX) project is planning upgrades to the toroidal field, plasma current and pulse length. This involves the replacement of the center-stack, including the inner legs of the TF, OH, and inner PF coils. A second neutral beam will also be added. The increased performance of the upgrade requires qualification of the remaining components including the vessel, passive plates, and divertor for higher disruption loads. The hardware needing qualification is more complex than is typically accessible by large scale electromagnetic (EM) simulations of the plasma disruptions. The usual method is to include simplified representations of components in the large EM models and attempt to extract forces to apply to more detailed models. This paper describes a more efficient approach of combining comprehensive modeling of the plasma and tokamak conducting structures, using the 2D OPERA code, with much more detailed treatment of individual components using ANSYS electromagnetic (EM) and mechanical analysis. This capture local eddy currents and resulting loads in complex details, and allows efficient non-linear, and dynamic structural analyses.

  7. Readying Cavalli's operas for the classroom: textbooks, editions, and the teaching of a non-canonic composer

    2014-12-01

    Full Text Available My title pays homage to a recent volume of essays edited by Ellen Rosand and devoted to the scholarship and performance of Francesco Cavalli’s operas. Yet if love of wordplay inspired it, coincidence confirmed it. The volume appeared in print just months after my own foray into editing, albeit of a very different kind. I had been asked to prepare one of the volumes of The Oxford Anthology of Western Music, specifically the part that deals with Baroque music. As its title suggests, the anthology accompanies The Oxford History of Western Music: College Edition, the one-volume abridgement of Richard Taruskin’s five-volume behemoth prepared by Christopher H. Gibbs. I was charged with assembling scores of the works discussed therein and writing commentary on them, based on Taruskin’s own in the larger text. While I was left free to do as I pleased with the latter, such was not the case with the former. Thus music after 1700 occupies more pages than that before 1700, and the earlier repertory features some notable lacunae. That one of the biggest is Francesco Cavalli comes as no surprise, for in the course of the more than 3,800 pages of Taruskin’s original the composer receives exactly three sentences.

    Sovtić Nemanja

    2013-01-01

    Full Text Available In this text, Rudolf Brucci’s opera Gilgamesh is viewed in the light of Ralph Locke’s “All the Music in the Full Context” Paradigm which promotes the approach that one should search for the exotic elements in musical works first in the discursive components (title, program, accompanying notes, visual representations (costume, scenery and a “horizon of expectations” of a particular culture, and only then to observe exoticism as the aspect of a musical style. In the light of this Paradigm, “exoticism” of the opera Gilgamesh is detected at the level of the music material and compositional procedures, but not in the dramaturgical profiling of characters, narrative adaptation of the Sumerian epic, costumes and scenery. The plot, costumes and the scenery of the opera do not construct the Orient with either positive or negative projections attributed to it by the Western European Orientalist discourse, but portray Gilgamesh and Enkidu as ancient mythic protagonists on the margin of the (not-always exoticist once/now binarism. The musical language of the opera, which abounds in the usage of oriental musical scales and citations, indicates that oriental/exotic was one of the author’s “target levels” when conceiving and composing Gilgamesh. Brucci, however, did not build the “ethnological model” in his opera, but gave oriental scales and “exotic” musical citations their meaning within the Western musical tradition, which is why his approach can be compared with the “veiled exoticism” of the French composers of the late nineteenth and the early twentieth centuries. In the light of the self/other binarism, reaching for the exotic in Gilgamesh can be presented as an auto-exotic creative behavior of Brucci as a composer who perceives his “minority identity” in a relation to an imaginary referential system of the Center. However, I am more inclined to see Brucci’s identificational intention in his advocacy of the

    The organization of health care establishments and perioperative care are essential for ensuring the quality of care and safety of patients undergoing outpatient surgery. In order to correctly inventory these organizations and practices, in 2013-2014, the French society of anaesthesia and intensive care organized an extensive practical survey in French ambulatory surgery units entitled the "OPERA" study (Organisation periopératoire de l'anesthésie en chirurgie ambulatoire). From among all of the ambulatory surgery centres listed by the Agences régionales de santé (Regional health agencies, France), 206 public and private centres were randomly selected. A structural (typology, organization) survey and a medical-practice survey (focusing on the management of postoperative pain, nausea and vomiting as well as the prevention of venous thromboembolism) were collected and managed by a prospective audit of practices occurring on two randomly selected days. The latter was further accompanied by an additional audit specifically focussing on ten representative procedures: (1) stomatology surgery (third molar removal); (2) knee arthroscopy; (3) surgery of the abdominal wall (including inguinal hernia); (4) perianal surgery; (5) varicose vein surgery; (6) digestive laparoscopy-cholecystectomy; (7) breast surgery (tumourectomy); (8) uterine surgery; (9) hallux valgus and (10) hand surgery (excluding carpal tunnel). Over the 2 days of observation, 7382 patients were included comprising 2174 patients who underwent one of the procedures from the above list. The analysis of these data will provide an overview of the organization of health establishments, the modalities thus supported and compliance with standards.

    Full Text Available The essay describes the conditions and process of the supply of timber from the forests managed by Opera of Santa Maria del Fiore during the construction of Brunelleschi’s dome. Furthermore it analyzes the employ of wooden structural elements in support of the building’s masonry and for scaffolding and other temporary apparatuses devised by the Florentine architect. The numerous supply contracts and payments allocated to the haulage contractors reveal the route followed by wooden materials from the forest to building yard and allow the identification of the various types of labor involved in the felling of trees, the preparation of logs and their transport. These documents specify the amount of timber ordered from each hauler and, in some cases, even the linear and volumetric dimensions of the wooden elements ordered by Opera. Such information has permitted the formulation of hypotheses about the structure and dimensions of temporary wooden scaffolding. The number of logs ordered, calculated year by year and related to the successive phases of the construction, reflect the changing requirements of wood for the building process as well as the political and economic situation of the city of Florence (wars, financial crises during the two decades of the construction of the cathedral’s great cupola. The resolutions of the consuls of Wool Guild and the Opera wardens regarding the forest administration testify to the existence of a bureaucratic structure charged with overseeing the woodland heritage. These sources vividly render the difficulties encountered in reconciling the intense exploitation of the forest for economic ends with the livelihood of the local population and, at the same time, with the necessity of ensuring the regeneration of a precious but exhaustible resource entrusted to the Opera’s care.

    The OPERA experiment (Oscillation Project with Emulsion t-Racking Apparatus) aims to check Super-Kamiokande results, searching for tau neutrinos apparition in an originally pure muon neutrino beam, by the direct observation of the tau decay topology. The OPERA target is made of walls of bricks, whose structure consists in a sandwich of lead plates and emulsion plates. The emulsions are very precise trajectographs ({approx} 1 micron) which will be used in a huge quantity during the experiment. Therefore, their analysis requires an automatic and dedicated acquisition system. First, this thesis aimed to tune and to develop the first French scanning system. The performances presented showed that the precision of the system respects the OPERA requirements and its speed is expected to increase in a few months. Then, the pion/muon separation at low energies was studies and test beams, designed to answer this problem, were performed. The firs results, showing the possibility of a separation, were presented. Finally, a reconstruction program dedicated to these stopping particles and taking into account the scanning efficiencies has been developed and tested. (author)

    Full Text Available A eficácia na transferência de derivados de petróleo através de dutos motiva a execução deste trabalho. O objetivo principal é a modelagem do scheduling de um poliduto, isto é, um sistema de dutos que transporta diferentes derivados de petróleo. O poliduto em estudo com 93,5 km de extensão conecta uma refinaria a um terminal portuário. Foi desenvolvido um modelo de otimização baseado na união de Constraint Logic Programming (CLP e Mixed Integer Linear Programming (MILP. O modelo utiliza uma abordagem de decomposição do problema, com representação temporal contínua e calcula janelas de tempo (restrições temporais que devem ser respeitadas. A abordagem híbrida CLP-MILP proporcionou a solução de cenários reais em tempo computacional da ordem de segundos. A resolução computacional do modelo proposto evidenciou novos pontos de operação para o poliduto, proporcionando ganhos operacionais significativos. O modelo implementado configura uma ferramenta de auxílio para tomada de decisões operacionais no cenário estudado.This work is motivated by the need of optimization in the pipeline-oil distribution scenario. The considered problem involves the short-term scheduling of activities in a specific pipeline. The pipeline is 93.5 km in length, and it connects refinery and harbor tankfarms, conveying different types of commodities (gasoline, diesel, kerosene, etc. An optimization model was developed to determine the pipeline scheduling with improved efficiency. Such model combines Constraint Logic Programming (CLP and Mixed Integer Linear Programming (MILP in an integrated CLP-MILP framework. The proposed model uses decomposition strategies, continuous time representation, and intervals that represent time constraints (time windows. Real cases were solved in a reduced computational time (order of seconds. The computational results have demonstrated that the model is able to define new operational points to the pipeline

    Tunisia is a country in which three quarters of the territory is arid to semi-arid with limited water resources. Decreasing water scarcity and water pollution constitute a big challenge for water stakeholders particularly in rural areas and poor communities. The main factors influencing water availability in this Mediterranean country is, among others, overexploitation of non-renewable resources and diffuse pollution. Due to intensive agriculture in proximity of rivers and continuous use of pesticides, there is a potential risk for contamination of waterbodies by the agrochemicals used. This could have a negative impact on agricultural production as well as human health and threaten in priority the north part of the country where 82% of surface water is available. Despite this situation, no catchment monitoring program is currently put in place since it is expensive and require large investment. In this study, we established a methodology using the PegOpera modeling tool to assess the potential risk of pesticides contamination of surface water at the scale of a rural catchment situated in the northwestern part of Tunisia, the Joumine basin, draining an area of 418 km2 and devoted to agriculture, mainly rainfed cereal crops. In the downstream part of the basin, the Joumine dam was built in 1984 to provide water for irrigation and drinking purposes. We performed a survey with catchment farmers to report management practices in the area as well as spatial and temporal information about pesticide compounds, timing and application rate from which we identified the most used pesticide molecules. The SIRIS method (System of Integration of Risk with Interactions of Scores) was applied to classify compounds used according to the risk that they present to the aquatic environment and therefore to identify those chemicals that should be monitored (Guerbet et al., 2002; Le Gall et al., 2007). According to the results of this classification, we selected 6 molecules to study in

    2013-12-01

    Full Text Available This paper reviews Gaston Leroux’s Phantom of the Opera in the context of the social and cultural changes of the metropolis Paris at the end of the 19th century. The Phantom of the Opera, a success in the literary world and widely proliferated in its musical and film renditions afterward, is considered and interpreted mainly in the literary and artistic tradition. In this paper, however, this work will be considered from an urban sociological perspective, especially from that of Walter Benjamin, who developed the theory of the urban culture, focusing on the dreaming collectives at the end of the 19th century. Leroux’s novel can be regarded as an exemplary social form of the collective dreams of the period expressed in arts, architectures, popular stories and films and other popular arts. Given the premise that the dream images in the novel, so-called kitsch, reflect the fears and desires of the bourgeois middle class that were pathologized in the figure of the ghost, this paper reveals the cultural, social and transnational implications of the Ghost-Image in relation to the rapidly changing borders of the 19th century metropolis.

  10. Facilitating Public Access to the Arts: Applying the Motivation, Opportunity, and Ability Framework to the Case of the UK Royal Opera House

    Directory of Open Access Journals (Sweden)

    2017-07-01

    Full Text Available In recent years, arts organizations in the UK have faced challenging times due to severe funding cuts from government and depressed box office sales during the recession. In the UK’s current cultural policy, ‘social impacts’ of the arts are highly emphasized and state interventions are intensified both in terms of finance and legitimacy. What is necessary for arts organizations to produce social impacts is their active provision of ‘deliberate extra activities’, which are generally conducted in the form of education, community, participation or outreach programs. The Royal Opera House (ROH case study provides an apt example of how to exercise these activities effectively to deliver social impacts. Based on Rothchild’s theoretical Motivation, Opportunity, and Ability (MOA framework, this study aims to find out how the UK Royal Opera House stimulated motivation among arts audiences and facilitated opportunities for them, thereby allowed them to translate motivation into action. The results show that the ROH implemented several specific strategies: ‘interest triggerings,’ ‘value creation and transmission,’ relationship building and management,’ and education. These strategies can motivate potential arts consumers to be familiar with classic arts, which lowers psychological barriers and stimulates intrinsic motivation to satisfy long-lasting and self-sustaining cultural needs.

    This study was undertaken to compare the central nervous system (CNS) tolerability profiles of the extended-release formulations of oxybutynin chloride and tolterodine tartrate in the treatment of women with overactive bladder (OAB), as observed in the OPERA (Overactive bladder: Performance of Extended Release Agents) trial. The OPERA trial was a randomized, double-blind, active-control comparison of the efficacy and safety of extended-release oxybutynin (10 mg/d) and extended-release tolterodine (4 mg/d) given to 790 women with OAB for 12 weeks. The incidence of reported CNS events was compared between the treatment groups by using the Fisher exact test. The incidence of CNS adverse events was 9% and 8% for the oxybutynin and tolterodine treatment groups, respectively. The difference between groups was not statistically significant. All reported CNS adverse events were rated as mild or moderate in severity. There were no serious treatment-related adverse events in either group, and discontinuation because of a CNS adverse event was infrequent. The extended-release formulations of oxybutynin and tolterodine were observed to be associated with a similar low incidence of CNS adverse events, which were mostly mild or moderate in severity.

    Full Text Available Objetivou-se examinar a hipótese de eficiência semiforte de mercado (HEM nos contratos futuros de soja do Brasil, negociados na BM&F-Bovespa, aplicando análise espectral e regras de filtragem. Os resultados comparados da teoria indicam conclusões diversas quanto à HEM em mercados futuros de commodities agropecuárias. Entretanto, a eficiência semiforte de mercado parece não se confirmar em preços futuros de soja. Após o teste, rejeitou-se o modelo de passeio aleatório para os preços futuros de ajuste da soja brasileiros. A avaliação ilustrou o potencial de arbitragem dos contratos, classificado posteriormente aplicando-se regras de filtragem com base em diversos intervalos de variação percentual dos preços de ajuste do grão na bolsa. Compuseram-se diversas estratégias operacionais de compra e venda no período amostral entre 2004 e 2010 com base nos intervalos. Classificando os resultados financeiros e percentuais de acertos lucrativos dos negócios, identificaram-se determinados subperíodos com maior incidência de ganhos positivos. A diferença entre os resultados pode ser atribuída ao recente regime de preços de commodities, prevalecente no mercado após 2008. Também, o potencial de lucratividade possibilita atrair novas operações de hedge e especulativas para o mercado futuro de soja brasileiro, aumentando o volume de negócios no mercado futuro de soja da BM&F-Bovespa. A lucratividade potencial examinada pode atrair novas operações de hedge e especulação, incrementando o volume negociado. O aumento dos negócios consolidará o contrato como uma alternativa eficiente de mitigação de risco e geradora de operações lucrativas no mercado futuro agropecuário brasileiro. Adicionalmente, o processo de descoberta de preços avaliando a constelação de preços futuros de um contrato desenhado com as características próprias da soja brasileira aumentará a eficácia administrativa do processo de comercialização do

    Full Text Available From 1946 the artist John Piper designed sets for eight of Benjamin Britten’s operas. In this article, John Piper’s contribution to the renaissance of English opera is considered in the wider context of the artistic and political reconstruction of England after the Second World War. During the War, Piper was one of the artists who redefined Englishness. As an abstract artist turned architectural painter, he created a pastoral vision of the national heritage whose preservation had become necessary. The designs form a part of Piper’s pictorial work whose logical conclusion found expression in stained-glass windows. From the architectural designs for The Rape of Lucretia to the window he designed for the new Coventry Cathedral and to the last opera sets for Death in Venice, he created backdrops for Britten’s works that provided a sense of aesthetic continuity whilst reflecting the contradictions of opera as a social form of art in post-war Britain.

    Directory of Open Access Journals (Sweden)

    Anna Ficarella

    2016-12-01

    Full Text Available An unconventional work like Aufstieg und Fall der Stadt Mahagonny, written by Weill and Brecht between 1927 and 1930, provides an opportunity to address, through a multi-disciplinary didactic approach, a crucial moment in the evolution of opera theatre in the German cultural area in the years immediately following WWI. In the Germany of those years, operatic and theatrical institutions had been undermined both by the impact of the new media, above all by silent cinema, and by the disruptive social pressure of urban mass culture during the Weimar Republic. In this context, the ‘epic’ model of musical dramaturgy developed by Brecht and Weill in Mahagonny appears as an attempt to renew, or possibly reject altogether, the 19th-century work by using its very means.

    Full Text Available Este artigo apresenta uma discussão sobre os valores humanos a partir de uma situação de abrupta mudança organizacional gerada por uma operação de aquisição. O objetivo desta pesquisa teórico-empírica foi compreender como os funcionários que vivenciaram a operação de aquisição da instituição financeira em que trabalhavam conseguiram lidar com essa situação a partir dos valores humanos. A pesquisa é qualitativa, descritiva, de corte temporal seccional com perspectiva longitudinal. Os dados foram coletados por meio de entrevistas semiestruturadas e interpretados pela técnica da análise de conteúdo. A lente teórica deste estudo se sustentou no modelo de Rohan (2000, sobre o sistema de valores pessoais, o qual traz como inovação a ideia de que os valores têm mais do que um papel na sobrevivência dos indivíduos por serem, conforme denomina a autora, guias para a melhor forma possível de viver. Os resultados nos levam a concluir que, embora haja divergências nos sistemas de valor pessoal e de prioridade social dos entrevistados, ou seja, no modo como eles encaram e guiam seus comportamentos e atitudes diante de uma mesma situação, eles encontraram a melhor forma possível de viver perante a operação de aquisição, na medida em que conseguiram respeitar e preservar seus valores pessoais para se adaptarem às novas circunstâncias de trabalho, sem que isso lhes representasse sofrimento. Essa interface entre os valores humanos dos entrevistados e a mudança organizacional por eles vivenciada ressalta, portanto, aspectos que vão além da adaptação dos indivíduos para sobrevivência e para a participação em uma sociedade. Ao mesmo tempo, mostra que a complexa formação de um grupo pode conter sistemas de priorização de valores pessoais e sociais diversos em diálogo, sem com isso implicar homogeneidade para lidar com uma mesma situação. Essa compreensão justifica, finalmente, o motivo pelo qual os funcion

  10. Reconstruction et analyse des gerbes électromagnétiques dans l'expérience OPERA et étude des oscillations neutrino avec détection d'électrons

    CERN Document Server

    Brunet, Florian

    An international program is ongoing to measure the neutrino oscillation phenomenon and to determine the neutrino mixing matrix (MNSP) parameters. OPERA is a long-baseline neutrino experiment located at the Gran Sasso Laboratory in Italy, 730~km from CERN, downstream in the CNGS neutrino beam. The OPERA experiment is designed and optimised for a direct appearance search of νµ → ντ oscillations. It can also detect the νµ → νe oscillation driven by sin(2θ13)2 , where θ13 is the last mixing angle finally measured by the Daya Bay, RENO, and Double Chooz experiments in 2012. To observe the presence of ντ interactions in the beam, the OPERA detector is composed of calorimetric targets made of a modular structure called the "brick": a sandwich of lead plates interspaced with emulsion layers. The latter allows reconstructing tracks of charged particles produced in the neutrino interactions with a micrometric resolution. The search for the νµ → νe oscillation signal is based on the capability of ide...

  11. L’Opéra en version anglaise : un enjeu esthétique ou sociologique ? Opera in English Translation: An Æsthetic or Sociological Issue?

    Directory of Open Access Journals (Sweden)

    Pierre Degott

    2009-11-01

    Full Text Available The history of English opera has always been conditioned by the ambivalent attitude of English-speaking audiences towards their own language. A close scrutiny of the London theatre seasons of the XVIIIth and XIXth centuries does indeed show a strong split, in terms of aesthetic and sociological considerations, between, on the one hand, the aristocratic Italian seasons of the King’s Theatre in Covent Garden, and the English opera seasons organised by the "lesser" theatres on the other. The aim of this paper is to assess the sociological implications of the use of the English language on the operatic stage. Far from defending the – now absurd – idea of the superiority of English over original versions, this paper shows that English versions of the main repertory were sometimes far ahead of their Italian counterparts at least in terms of artistry and musical authenticity. An example of such a phenomenon is provided by the Old Vic in the 1920s, when Edward Dent’s spirited translations of Mozart’s operas won the theatre the name of "the Home of Mozart." A comparative study of several translations of Mozart’s Le Nozze di Figaro further displays the interrelatedness of the sociological and aesthetic issues of operatic translation.

  15. To a cultural perspective of mixed reality events: a case study of event overflow in operas and concerts in mixed reality

    Lucas, Jean-François; Cornish, Tracy; Margolis, Todd

    2012-12-01

    Mixed reality defines the sharing of a space-time between the real and the virtual world. The definition of this concept is further extended when virtual worlds such as Second Life® (SL) are included. Through cultural events such as concerts and operas, we will see that the main goal of these kinds of projects is not simply to offer a video and audio broadcast of these events in the digital dimension. The current challenge is to create interactions between the individuals who are in different shared spaces. By studying the unfolding of these events in its various phases-before, during, and after-we examine the culture of the event. We question how the culture of the event can be transposed in a mixed reality display, and how this kind of event can affect people on both sides of the "membrane" made by the technical configuration. Beyond the alignments and adjustments that we can see between the different individuals involved in these events, we examine more broadly the changes and mutations of the culture of the event in this specific configuration.

    Full Text Available Tendo em vista o aumento do transporte marítimo no mundo e a consequente demanda por operações nos portos, os operadores buscam formas de minimizar o tempo de permanência dos navios no porto. Para atracar um navio, os portos necessitam ter disponíveis diversos recursos. Assim, planejar a designação de recursos eficientemente para não atrasar a atracação dos navios é vital para os portos. Esta designação é dinâmica, pois atrasos e antecipações na chegada dos navios ocorrem por diversos fatores demandando assim que ela seja atualizada constantemente. Este artigo propõe um Multiagent System (MAS para resolução da designação de recursos de forma distribuída e em tempo real, visando reduzir o tempo de espera para atracação dos navios. Testes foram realizados em 27 cenários e os resultados mostraram que o MAS resolveu instâncias de teste de grande porte e nos cenários mais próximos do real, ele resolveu em um tempo pequeno e com soluções estáveis.

    Neutrino oscillations are the subject of most of the experiments looking at this particle. This mechanism uses the fact that neutrinos have mass to allow the transformation from one flavour to another one. The OPERA experiment will start to take data in spring 2006. Its goal is to proof this mechanism with no ambiguity using the appearance of tau neutrinos in the CNGS beam, which is made of muon neutrinos. This thesis presents a description of neutrino beams in general, and more precisely of the CNGS beam, which is sent from CERN to Gran Sasso in Italy. The neutrino flux are recalculated, and simulations have been performed in order to study miss positioning of the beam line elements. The OPERA detector is made of bricks containing a pile of lead plates and photographic emulsion films, of two trackers and two spectrometers. The high position resolution of the emulsions (< 1 {mu}m ), allows to identify the {tau} created by the tau neutrino charged current interactions. The brick localisation is made using a scintillator array. The pattern recognition in these scintillators as well as in the spectrometers is one of the part of this thesis. Furthermore, a muon identification algorithm has been set up. It allows to reject by a factor 20 the charm background. Future of neutrino oscillation physics is the building of more and more intense neutrino beams, in order to measure the last unknown parameters ({theta}{sub 13} and {delta}{sub CP}). The project of neutrino beam from CERN to the Fr us tunnel is fully revisited in the last part of this thesis. An optimisation of all the beam line element is proposed, and allows to reach a sensitivity to {theta}{sub 13} around one degree. (author)

    Abstract The story of Nini Anteh is an oral folklore of Sundanese, which has undergone a transformation into transgenre and translingual forms. Kesuma’s novel of “Nini Anteh” and an Opera Van Java (OVJ episode of “Nyai Anteh Penjaga Bulan” were the data of this study. The theory used in this research is the theory of transformation proposed by Riffaterre. Analysis of the data reveals expansion, conversion, modification, and similarities. Expansion in the OVJ did not appear in the slot, characters, and background for the story was made simpler than that in the novel. Expansion appeared in the variety of media used to invite laughter. Conversion in the OVJ was evident in simplified plot, character, and setting. In addition, the concept of beauty of Nyai Anteh in the novel was entirely changed for entertainment purposes. A gender bias background in the novel was turned into a neutral background in the OVJ. Although both works carried a Sundanese story, they show the notion of Indonesian by modifying the story through the use of characters and equipment in accordance with the modern age. In the novel efforts to build past linked to the life of the present can be seen as an attempt to prompt reflection, while modifications in the OVJ were to invite laughter. Both works share the same description of a woman who then decided to reside on the Moon because of love. What she did on the moon was weaving. These similarities indicate that there are things that would be passed on to subsequent generations, especially regarding the independence of women in producing textiles.  Keywords: Novel of Dongeng Nini Anteh, OVJ episode of Nyai Anteh Penjaga Bulan, transformation

CASUÍSTICA E MÉTODO: Foram estudados 83 pacientes com seguimento de um a 186 meses (média de 40,0 ± 47,4 meses. A fundoplicatura em três planos, proposta por Pinotti, foi realizada em 15,7% dos doentes e a fundoplicatura parcial posterior em 83,1%. A queixa pré-operatória principal foi disfagia, seguida de regurgitação e perda ponderal. A etiologia chagásica pode ser comprovada em 72,3% dos doentes, através de teste sorológico. RESULTADOS: No seguimento, 55,4% dos doentes estavam assintomáticos, 34,9% queixavam-se de disfagia esporádica, 14,4% de pirose, 8,4% de regurgitação e 2,4% de disfagia igual pré-operatória, sendo esses últimos re-operados, com melhora da sintomatologia. Refluxo gastro-esofágico foi constatado em 8,4% dos doentes. Outras complicações tardias foram: hérnia paraesofágica, deslizamento da fundoplicatura, esôfago de Barrett e neoplasia do esôfago. CONCLUSÃO: Os autores salientam a necessidade de acompanhamento clínico e endoscópico perene dos doentes, mesmo operados, devido à possibilidade de complicações tardias, em especial o câncer. Concluem por bons resultados tardios em relação à disfagia. Propõem, como alternativa à esofagectomia, a operação de Heller em pacientes portadores de megaesôfago grau IV com más condições clínicas, que não suportariam uma cirurgia de maior porte.

Integrating and interfacing the SMART system to include the functionality of a) semantic reasoning based on Jena, an open source semantic reasoning engine, b) semantic similarity calculation, c) recommendation based on spatiotemporal, semantic, and user workflow patterns, and d) ranking results based on similarity between search terms and data ontology. 2. Collaborating with data user communities to a) capture science data ontology and record relevant ontology triple stores, b) analyze and mine user search and download patterns, c) integrate SMART into metadata-centric discovery system for community-wide usage and feedback, and d) customizing data discovery, search and access user interface to include the ranked results, recommendation components, and semantic based navigations. 3. Laying the groundwork to interface the SMART system with other data search and discovery systems as an open source data search and discovery solution. The SMART systems leverages NASA, GEO, FGDC data discovery, search and access for the Earth science community by enabling scientists to readily discover and access data appropriate to their endeavors, increasing the efficiency of data exploration and decreasing the time that scientists must spend on searching, downloading, and processing the datasets most applicable to their research. By incorporating the SMART system, it is a likely aim that the time being devoted to discovering the most applicable dataset will be substantially reduced, thereby reducing the number of user inquiries and likewise reducing the time and resources expended by a data center in addressing user inquiries.

    2010-01-01

    Full Text Available To assess the efficacy of Israel's strike on Osirak, one must determine Israel's strategic objectives and their material effects on Iraqi capabilities. The capacity of the facilities to produce fissionable material without detection remains in dispute. So, too, does the timeline—and therefore the imminence—of Iraqi acquisition of a nuclear option. The political cost-benefit equation in this case requires a fair dose of subjective judgment. How much did the Israelis delay the program? How much did Iraqi motivation increase post facto? Is military counter-proliferation a viable strategy? Was the potential Iraqi bomb worth risking a bold, unprovoked attack that inevitably drew the condemnation of the world? Did the raid, in toto, raise or lower the risk of regional proliferation in the Middle East? All of these considerations must factor into an informed opinion on the retrospective wisdom of Begin's decision.

  9. The issue of mass generation: the search for the Higgs boson in the D0 experiment at the proton-antiproton collider of Fermilab and the measurement of neutrino oscillation with OPERA

    International Nuclear Information System (INIS)

    Lucotte, A.

    2004-09-01

    The first part is dedicated to the theoretical aspects of the mechanism of mass generation in the standard model. The implications of this mechanism in the experimental field concerning the Higgs boson search and neutrinos are detailed. The second part presents the D0 experiment at the Tevatron (Fermilab) and describes in a detailed way the forward pre-shower (FPS) that is a sub-detector of D0 whose aim is to identify the electrons. FPS has required a specific triggering system linked to a data acquisition line. The third part is devoted to the Opera experiment that is planned to operate in 2006. The purpose of this experiment is to confirm the oscillations of muon neutrinos and tau neutrinos through the direct detection of a tau lepton in the pure beam of muon neutrinos produced in CERN. The author describes his contribution to the design and testing of the front-end read electronics of the Opera scintillator tracker. (A.C.)

    Full Text Available Resumo: A exploração de petróleo no Brasil é realizada por plataformas em alto-mar que demandam diversas cargas levadas por navios. Os portos para atender esses navios têm de manusear vários tipos de carga e, por conta dessa variedade, trechos para movimentar cada tipo de carga são determinados ao longo do cais, aumentando a complexidade do planejamento da atracação dos navios. Visando aumentar a eficiência na operação desses portos, este artigo propõe um modelo matemático para o problema de alocação de berços contínuos que difere das demais por apresentar restrições nas operações de cargas ao longo do cais. Utilizaram-se dados reais da Companhia Portuária de Vila Velha (CPVV para avaliar o modelo. Utilizou-se o CPLEX 12.6 para executar o modelo e instâncias de até 147 navios com 440 metros de cais foram resolvidas de forma ótima. Os resultados são apresentados e comparados com os alcançados pelo método manual atual, evidenciando ganhos importantes.

    Full Text Available As dificuldades de aprendizagem decorrentes do modelo de ensino encontrado nas escolas e os avanços dos recursos tecnológicos são fatores que influenciam a educação matemática. Os alunos apresentam um grau de dificuldade relevante com relação ao ensino-aprendizagem, causado pela falta de motivação, de aulas monótonas e sem relação com o cotidiano. Ao mesmo tempo, os recursos tecnológicos vêm sendo inseridos na educação de forma crescente, trazendo resultados positivos para o ensino. Considerando tais fatores, este trabalho analisou o uso de software educativo como auxílio na aprendizagem de matemática, apresentando-o como uma possibilidade de tornar as aulas mais motivadoras aos alunos. Para verificar se essa utilização traz resultados positivos para o ensino-aprendizagem, buscou-se tal comprovação por meio de estudo de caso de natureza exploratória realizado com alunos do 4º ano do ensino fundamental I, utilizando como ferramenta o software educativo Tux of Math Command. Realizou-se uma análise comportamental dos alunos na realização de operações matemáticas em diferentes situações: resolvendo as operações em sala de aula, e utilizando o jogo no laboratório de informática. Na utilização do software, verificou-se uma atitude mais instigante dos alunos do que na resolução das operações em sala de aula. Esse interesse foi decorrente da associação do jogo feita pelos alunos, não como problema a ser resolvido e sim como algo prazeroso e significativo, em oposição ao ocorrido em sala de aula, momento em que prevaleceu a insegurança e a necessidade de apresentar soluções. A pesquisa possibilitou afirmação do questionamento apresentado neste trabalho, confirmando que a utilização do software educativo auxilia o processo de ensino-aprendizagem de matemática.

    Full Text Available A extensão universitária desempenha um papel fundamental na formação cidadã dos alunos. Com isso, o Projeto Rondon que visa à integração social aliada ao voluntariado dos estudantes universitários, aborda em suas operações o tema de Saúde e Higiene Bucal. O objetivo deste trabalho foi de conscientizar sobre as práticas da higiene bucal e prevenção de doenças bucais e sistêmicas, incentivar a higiene pessoal dos alunos e ensinar a técnica correta de escovação dentária. As oficinas de higiene bucal ocorreram no ano de 2015, nos meses de janeiro e abril, no município de Itatuba-PB, na Operação Porta do Sol do Projeto Rondon e em São Paulo-SP, na E.E. Júlio de Mesquita Filho. A oficina consistiu de aula expositiva sobre higienização bucal, diálogo sobre a importância de uma boa escovação, seguida de dinâmica em que foi utilizado um modelo de escova de dente e boca de tamanhos ampliados. Em Itatuba-PB 125 pessoas participaram da oficina, e foram entregues 500 escovas de dente no período da operação. Já em São Paulo-SP cerca de 580 alunos participaram da ação e foram entregues mais de 500 escovas de dente. A distribuição de escovas de dente contribui para bons hábitos de higiene e ajuda a diminuir a influência das condições socioeconômicas. O estudante universitário atua como multiplicador de informações que são extremamente importantes e que contribuem para o bem-estar do público-alvo, ações preconizadas pelo Projeto Rondon e que atendem ao papel que a extensão universitária exerce dentro da comunidade.

Desta forma, iniciamos fazendo um balanço das novas abordagens historiográficas que persistem afastando a problematização, de forma socialmente orientada, da prática musical. A partir da proposição de uma História Social da Música, pensamos nas modalidades já existentes da construção do conhecimento da intersecção entre História e Música: a História da Música – de caráter nitidamente tradicional – e a Musicologia Histórica – voltada à música. Assim sendo, como centro questionador do trabalho, propomos apontamentos metodológicos para uma História Social da Música no caso da produção operística já que vivemos um interdito historiográfico neste gênero.Palavras-chave: História Social da Música – Ópera – Metodologia da História. Abstract: This work aims to propose a discussion of methodological possibilities of the use of opera production as a source of History. Thus, it begins by taking stock of the new historiographical approaches that persist without social questions. Based on the proposal of a Social History of Music, we think the modalities of the existing knowledge of the intersection between History and Music: a History of Music – clearly traditional – and Historical Musicology – dedicated to music. Thus, as the main question of this work, we propose methodological notes for a Social History of Music regarding opera production since we live in a historiographic interdict in this genre.Keywords: Social History of Music – Opera – Methodology of History.

    Full Text Available Na cidade contemporânea, o ambiente construído vem se modificando, observandose a presença de áreas em transformação de uso e esvaziamento. Em São Paulo, a transformação do ambiente construído mediante esse processo, frente à dinâmica de ocupação do solo e reconfiguração de áreas pela via do mercado imobiliário, parece se consagrar como a principal força de produção do espaço urbano, apesar da existência de instrumentos urbanísticos de indução do desenvolvimento da cidade, articulado pela regulação do poder público municipal. Uma intensiva e prioritária produção do espaço urbano, pela mão dos empreendedores imobiliários, vem sendo observada na cidade de São Paulo, revelandose desvinculada, de modo geral, de planos e projetos que poderiam induzir a realização de um espaço urbano planejado e sinérgico. Operações Urbanas (OU e Operações Urbanas Consorciadas (OUC são os instrumentos que em tese deveriam produzir uma articulação entre os interesses públicos e privados na produção de uma cidade mais justa e equitativa. O artigo apresenta uma análise crítica da OUC Vila Leopoldina-Jaguaré, que embora tenha se apresentado como possibilidade de transformação de um perímetro pela via do plano e projeto urbano, jamais foi regulamentada em lei, dando oportunidade a uma ocupação exclusivamente realizada por empreendimentos imobiliários.Built environment has changed in contemporary cities, and the presence of transformations in uses and emptiness of certain areas.

    Full Text Available The use of fertilizers and solid amendments in agriculture generates special interest for their effect on crop productivity, as well as for their environmental impact. The efficient use of these products demands knowing their physical and mechanical properties, the storing conditions effect and the operational characteristics of the metering systems used in the fertilizing equipment. In this context, the present study was developed with the purpose of evaluating the operational characteristics of different fertilizing metering systems and to determine the adequate metering system-product operational parameters, using powder lime, powder gypsum, granular 10-30-10 (N-P-K, and granular urea. Operational differences were established among four types of commercial fertilizer metering systems, including wire auger, star-shaped feed wheel, feed screw and ridged traction wheel. The study found that the unloading rate depends directly on the fertilizer metering system's rotating speed and is affected by particle size, repose angle, bulk density and moisture content of the applied product. The wire auger and star-shaped feed wheel metering systems were adequate for the distribution of powder products and the feed screw for granulated fertilizers. Furthermore, theoretical and experimental characteristic equations were established, defining curves for calibration and handling of the products plus the rotating speed range in which a better distributing behavior was achieved.A utilização de fertilizantes e corretivos sólidos na agricultura apresenta especial atenção tanto por seu efeito no incremento da produtividade dos cultivos, como por seu possível impacto ambiental. Para o uso eficiente desses produtos, precisam-se conhecer as características físicas e mecânicas, o efeito das condições de armazenamento e os detalhes de operação dos dosadores utilizados nos equipamentos para adubação.

    2009-10-01

    Full Text Available Although Gershwin’s Porgy & Bess (1935 is still regarded by most critics as the first African-American opera, Louis Gruenberg’s The Emperor Jones (1933 and Scott Joplin’s Treemonisha (1910 have recently challenged this sacrosanct position. Today, according to some researchers, Frederick Delius’s Koanga, based upon the central episode of the story of “Bras coupé” in George Cable’s The Grandissimes, composed in 1897 but whose première took place in 1904, could claim to be “actually the first”. This statement obviously raises the question of the definition of an “African–American” and the attendant criteria. Through an analysis of the libretto as well as the reviews of the various performances from the late 1890’s to the early 1970’s, this article aims to assess the African-American criteria of Koanga.

    Full Text Available Ad oggi in Letteratura sono presenti pochi studi di settore basati sulla valutazione del rischio rumore nei teatri lirici. Questa condizione si è venuta a creare nonostante in Italia prima il D.Lgs. 195/06, che ha recepito la Direttiva sul rumore 2003/10/CE, e poi le “Linee guida per il settore della musica e delle attività ricreative”, emanate ai sensi dell’art. 198 del D.Lgs. 81/08, obbligano i datori di lavoro a eseguire la valutazione dei rischi. Il presente lavoro riporta i risultati preliminari di uno studio pilota dell’esposizione professionale a rumore dei musicisti dell’orchestra sinfonica di un teatro lirico ita-liano. Sono state effettuate rilevazioni fonometriche su un campione rappresentativo dei componenti dell’orchestra, tramite dosimetri personali e analizzatori in frequenza. Le registrazioni sonore sono state effettuate durante le esecuzioni musicali nella fossa d’orchestra del teatro durante diverse tipologie di rappresentazioni teatrali. ------ To date, in the literature there are few field studies based on the noise risk assessment in opera houses. This condition has come about in spite of the Italian Leg. Decree n. 195/06, which transposed the noise Directive 2003/10/EC, and then the national "Guidelines for the music industry and recreation", issued under Art. 198 of Leg. Decree n. 81/08, oblige employers to perform noise risk assessment. This paper reports the preliminary results of a pilot study of occupational exposure to noise of the symphony orchestra musicians of an Italian opera. Surveys were carried out on a representative sample of members of the orchestra, using personal dosimeters and frequency analyzers. Sound recordings were made during the musical performances in the orchestra pit of the theater during the various types of theatrical performances.

    Full Text Available Resumo Este trabalho compara a influência do arrefecimento causado por um fluído em circulação e em contato com a parede interna de uma tubulação, que caracteriza a soldagem em operação. Foram avaliadas duas espessuras de parede do tubo e duas temperaturas do fluido interno. A soldagem foi realizada na ligação de conexões de aço ASTM A105 a um tubo API 5L Gr X60 com espessura de 11 mm e de 6 mm, utilizando os processos TIG (GTAW e eletrodo revestido (SMAW. A circulação do fluido foi feita com água potável em duas faixas de temperatura, de 6 a 10 °C e 18 a 36 °C. Durante a soldagem, a temperatura interna do tubo e a taxa de resfriamento foram monitoradas. Foram preparadas quatro juntas soldadas, avaliadas por ensaios não destrutivos (inspeção visual, líquido penetrante, partículas magnéticas e ultrassom, ensaios destrutivos (tração, dobramento, impacto, fratura e dureza e análise macrográfica e micrográfica. Os resultados mostram que, com os procedimentos adotados, não é necessária a adoção de cuidados especiais quanto à possibilidade de perfuração e vazamento de fluido durante a soldagem em operação. Houve evidencias que o efeito do arrefecimento do fluido no interior do tubo foi mais significativo que a espessura da parede do tubo no aumento da taxa de resfriamento. Ainda, a temperatura do fluido em circulação no tubo exerceu papel secundário no aumento da taxa de resfriamento e na redução da temperatura máxima na parede interna do tubo. O arrefecimento causado pelo fluido provocou aumento na dureza da ZF e ZTA, reduziu o alongamento no ensaio de tração, porém ainda em valores adequados. Estes comportamentos foram mais observados no tubo de menor espessura, de 6 mm. Foi possível, pelos resultados dos ensaios não destrutivos e ensaios mecânicos obtidos, qualificar os procedimentos de soldagem, com base nas normas especializadas neste processo.

    Full Text Available The sowing process for annual no-till crops affects the physical soil conditions around the seeds by exposing them to adverse conditions that may limit initial plant development and reduce potential yield. The use of seed drills that are not compatible with field conditions and the use of inappropriate seed drill speeds affect sowing performance. Therefore, this study aims to evaluate the effect of different seed drill types and operating speeds on soybean quality parameters and yield components. Two furrow opener (double disc and chisel and four operating speed (0.86; 1.22; 1.47 and 1.94 m s-1 treatments were used. The following variables were evaluated: mean number of days until emergence, plant distribution uniformity, sowing depth, area of the soil disturbed, crop stand and grain yield. Overall, the chisel furrow opener provided a greater sowing depth and increased the disturbed soil area more than the double disc furrow opener. Increased operating speeds reduced crop stands and yields and increased the disturbed soil area. Em culturas anuais submetidas ao sistema plantio direto o processo de semeadura afeta o condicionamento físico do solo ao redor das sementes expondo as mesmas a condições adversas, podendo limitar o desenvolvimento inicial das plantas e minimizar o potencial produtivo. O uso de sulcadores não condizentes com a situação de campo e de velocidades inadequadas são fatores que afetam o bom desempenho da semeadura. Nesse contexto, este trabalho teve por objetivo, avaliar o efeito de diferentes sulcadores e velocidades de operação sobre parâmetros de qualidade de semeadura e componentes de produtividade da cultura da soja.

    Directory of Open Access Journals (Sweden)

    Xavier Cervantes

    2009-11-01

    Full Text Available This article surveys several examples of visual, and especially graphic, satires of Italian opera in early eighteenth-century Britain. They often targeted other imported dramatic genres or non-dramatic types of entertainment, such as pantomime and masquerades; these were connected to Italian opera because of their immorality and the threat they posed to patriotism and national ethics. These images can be considered the visual equivalents of many contemporary printed satires and critiques. However, even if these documents are genuine iconotexts, including textual fragments under various guises, their iconic specificity enlarged the scope for various types of satirical discourse, as appears in the detailed study of a striking example of intericonicity.

    Walter Zidaric

    2009-10-01

    Full Text Available La Fanciulla del West is a “horse opera” resulting from the second collaboration between David Belasco and Giacomo Puccini. This work, specially composed for the American stage, which had its world premiere at New York’s Metropolitan Opera in December 1910, paved the way for American composers who increasingly focused on American History in their quest for a “national” opera. For the first time, Puccini resorted to genuine Indian music, a Zuni melody, which he re-elaborated for dramatic purposes and associated with the nostalgic mood of uprooted people, the miners who left their home country for America. The Other – the native American viewed from the vantage point of the white, as well as the foreigner – no longer represented a threat, as had been the case in the operatic repertoire before, but became part and parcel of a multicultural society, like the Italian immigrant to whom Puccini also paid tribute. The Zuni melody, which opens and closes the opera, contributes to giving a genuine twist to a score which is the first one to tackle the foundations of the American nation.

    Full Text Available Resumo A água para consumo humano, quando presente nos sistemas prediais, é passível de diversas formas de desperdício. Por vezes, os gastos excessivos se devem ao término da vida útil dos equipamentos hidrossanitários e à negligência quanto à necessidade de manutenção. Este artigo apresenta as condições de operação dos equipamentos hidrossanitários de dez edificações públicas da cidade de Joinville, SC. Detectou-se que mais de 56,0% das bacias sanitárias e mictórios possuíam vazamentos. Foram encontradas 2,5% de torneiras com filetes ou gotejamentos constantes, bem como 31,0% que apresentaram vazamento não mensurável na válvula ao serem acionadas. As vazões de torneiras, bebedouros e chuveiros foram medidas e comparadas com os valores referenciados nas normas brasileiras e certificações ambientais LEED e AQUA. Ao fim, são apresentados os indicadores de consumo dos dez edifícios, cujas médias variam de 16,6 a 69,3 litros/usuário por dia.

    Full Text Available Após 16 anos do Estatuto da Cidade, lei federal que estabelece as diretrizes da política urbana de aplicação municipal, a recente normatização do Estatuto da Metrópole se apresenta como novo cenário para os questionamentos quanto ao planejamento de dimensão urbano-regional. Diante deste debate, o presente artigo pretende traçar algumas reflexões sobre os desafios de reescalonamento do ordenamento territorial à luz da gestão social da valorização da terra. Como ilustração da lógica institucional fragmentária do planejamento, no uso controverso de instrumentos de recuperação de mais-valia para o financiamento de grandes projetos, apresenta-se a disposição excludente da Operação Urbana Consorciada Linha Verde (antiga BR-116, instrumento implementado em 2012 pelo município de Curitiba, definindo um perímetro de atuação municipal em um eixo de caráter regional, com impacto e abrangência que extrapolam seus limites municipais.

    Love, Sex, and Choices (LSC) is a 12-episode soap opera video series developed to reduce HIV risk among at-risk Black urban women. We added a video guide commentator to offer insights at critical dramatic moments. An online pilot study evaluated acceptability of the Guide Enhanced LSC (GELSC) and feasibility of Facebook© advertising, streaming to smartphones, and retention. Facebook© ads targeted high HIV-prevalence areas. In 30 days, Facebook© ads generated 230 screening interviews; 84 were high risk, 40 watched GELSC, and 39 followed up at 30 days. Recruitment of high-risk participants was 10 per week compared to 7 per week in previous field recruitment. Half the sample was Black; 12% were Latina. Findings suggest GELSC influenced sex scripts and behaviors. It was feasible to recruit young urban women from a large geographic area via Facebook© and to retain the sample.

    Full Text Available Em sistemas de operações integradas, os reais benefícios da integração só podem ser obtidos e reconhecidos se o projeto e a estrutura organizacional decorrente se tornam compatíveis com a mudança a ser introduzida. Além disso, há a necessidade de se desenvolver uma metodologia para a condução da atividade de projeto, o que inclui a sua gestão e instrumentalização. Da definição de um modelo de referência para o projeto organizacional, desenvolve-se a racionalidade do processo de projetar. A partir desta racionalidade e dos seus elementos constituintes, identifica-se uma abordagem metodológica que tenha a completude necessária, no sentido de se manter a coerência entre a estrutura e a mudança a ser introduzida, bem como de servir como instrumento para a sua operacionalização. Portanto, afora desenvolver a racionalidade do processo de projetar, destaca-se como contribuição deste trabalho a identificação de uma abordagem que, além de definir um processo de gestão da atividade de projeto organizacional, orientando a sua instrumentalização, poderá servir como uma estratégia para o refinamento e a validação do modelo. Tal metodologia contribui para a construção de uma Teoria Organizacional de Projeto para os sistemas organizacionais, em particular para os sistemas de operações integradas.The real benefits of integration, in an integrated operations system, can only be obtained and recognized if the implemented organizational design and structure are compatible with the introduced change.

Colunas de 1,0; 1,3; 1,6; 1,9 e 2,0 m foram preenchidas com esses materiais, para filtragem de água residuária da suinocultura (ARS, o que foi realizado em três replicatas. Para monitoramento da perda de carga nos filtros, foram instalados piezômetros. O tempo de operação dos filtros, até que a taxa de filtração passasse a ser menor que 0,2 L m-2 s-1, foi de 100 a 150 min. As taxas de remoção de sólidos em suspensão (SS e de sólidos totais (ST foram, respectivamente, de 90 a 99% e de 43 a 57%, utilizando-se filtros de serragem de madeira, e de 81 a 96% e de 50 a 56%, usando-se filtros de bagaço de cana-de-açúcar. A eficiência de filtragem aumentou com o passar do tempo, ocasionada pela obstrução gradativa dos poros e pela retenção de sólidos da ARS nas colunas filtrantes. A altura da coluna filtrante não alterou significativamente a eficiência dos filtros na remoção de SS.This work consisted of study of operation of organic filters utilizing sugarcane bagasse and sawdust as filtering material.

    Full Text Available The main source of soil structure degradation in coffee plantation is the machinery traffic because these operations may cause soil compaction affecting the crop development. This study aimed to generate the load-bearing capacity models for a Red-Yellow Latosol and to determine through the use of these models the soil susceptibility to compaction of the coffee plantation due to the implantation time and the compaction caused by the machinery traffic on the traffic lines located at the top and bottom of the ground. This study was carried out in the EPAMIG Experimental Farm, located at Três Pontas, MG, in coffee plantations (Coffee arabica L. with 2, 7, 18 and 33 years of establishment. To obtain the load-bearing capacity models, 12 undisturbed soil samples were randomly collected in the 0-3 cm and 15-18 cm layers in the position between the rows for each establishment time of the coffee plantation. It was also randomly collected 10 undisturbed soil samples for each establishment time of the coffee plantations along the tractor traffic lines located at the top and bottom of the ground. These undisturbed soil samples were used in the uniaxial compression tests. The use of the load-bearing capacity models allow to identify the soil susceptibility to compaction due to the implementation time of the coffee plantation and the compaction caused by the machinery traffic on the traffic lines located at the top and bottom of the ground. The percentage of compacted soil samples increases with the establishment time in the layer of 15-18 cm.A principal fonte de degradação da estrutura do solo na exploração cafeeira é o tráfego de máquinas, pois essas operações podem causar compactação do solo, afetando o desenvolvimento da cultura. Neste estudo, objetivou-se gerar os modelos de capacidade de suporte de carga para um Latossolo Vermelho-Amarelo e determinar por meio do uso desses modelos a suscetibilidade à compactação do solo, pelo tempo de

    Full Text Available RACIONAL: Desde 1979 este grupo de autores executa esplenectomia conservadora através de esplenectomia sub-total e autotransplante esplênico. Estes procedimentos foram realizados em mais de 300 pacientes para tratar diferentes condições patológicas. OBJETIVO: Apresentar proposta original e inédita em seres humanos de esplenectomia subtotal, preservando apenas o pólo superior do baço por via laparoscópica e esplenectomia total complementada por implante autógeno de tecido esplênico, também pela via laparoscópica, como nova forma de tratamento da dor severa devida à isquemia do baço. MÉTODOS: Três pacientes com intensa dor no hipocôndrio esquerdo foram submetidos a grande número de exames para concluir que sua dor era provocada por isquemia de parte do baço. A dor era resistente a todos os métodos conservadores utilizados. Decidiu-se, então, pelo tratamento cirúrgico por meio da esplenectomia subtotal, preservando o pólo superior do baço suprido pelos vasos esplenogástricos em dois casos, e esplenectomia total complementada por implante no omento maior de 20 fragmentos retirados desse baço, no terceiro caso. As três operações foram realizadas por via laparoscópica. Os três doentes foram acompanhados com exames hematológicos, imunológicos, tomográficos e cintilográficos. RESULTADOS: Esses procedimentos foram conduzidos sem risco para os paciente e com sangramento mínimo. Não houve dificuldade técnica nem complicações per ou pós-operatórias. No seguimento, não foram constatadas anormalidades, comprovando-se a vitalidade e a função dos remanescentes esplênicos. A dor esplênica desapareceu desde o dia da operação e não retornou durante o período de acompanhamento. CONCLUSÃO: A esplenectomia subtotal e os auto-implantes esplênicos são factíveis por via laparoscópica, de maneira segura para os doentes e devem deve ser considerados no tratamento da dor de origem isquêmica do ba

    Rodrigo Gomes da Silva

    Full Text Available OBJETIVOS: Para se evitar o estado asplênico, muitas medidas preservadoras do baço têm sido propostas na literatura, como a esplenorrafia, a esplenectomia parcial com preservação dos vasos hilares e o auto-implante de tecido esplênico. A esplenectomia subtotal, com conservação do pólo superior do baço, nutrido apenas pelos vasos esplenogástricos é uma alternativa quando o pedículo esplênico precisa ser ligado. O objetivo deste estudo foi avaliar a influência das esplenectomias parcial, subtotal e total na distribuição da Escherichia coli no sistema mononuclear fagocitário. MÉTODO: Foram estudados 32 ratos divididos em 4 grupos: operação simulada (mantendo todo o baço, esplenectomia parcial, esplenectomia subtotal e esplenectomia total. Após cinco semanas da operação, uma alíquota de Escherichia coli marcada com 99m-tecnécio foi injetada por via venosa. Após 20 minutos, os animais foram mortos, e o baço, os pulmões e o fígado foram retirados para se verificar a distribuição das bactérias marcadas. RESULTADOS: A quantidade de Escherichia coli no tecido esplênico foi maior no grupo com o baço íntegro em comparação com os grupos esplenectomia parcial e subtotal. A distribuição da bactéria marcada pelo baço não diferiu nos grupos com esplenectomia parcial ou subtotal. A quantidade de bactérias no pulmão foi maior no grupo esplenectomia parcial do que a do grupo com esplenectomia subtotal. Após esplenectomia subtotal, a distribuição da bactéria marcada foi maior no fígado em comparação com a captação desse órgão nos demais grupos. CONCLUSÕES: O pólo superior do baço, suprido apenas pelos vasos esplenogástricos, tem capacidade de remover da circulação bactérias vivas, mostrando que, mesmo sem a vascularização pelo pedículo esplênico, há uma eficiente depuração sangüínea. A distribuição da Escherichia coli pelo sistema mononuclear fagocitário apresenta comportamentos diferentes

    Full Text Available En Angleterre, les opéras et les chanteurs italiens ont été, dès le départ, objets de ridicule et d’invectives. Cependant, les sommes d’argent importantes, le soutien et le mécénat dont cet art bénéficia de la part des élites intellectuelles, culturelles et politiques du royaume semble suggérer que l’opéra a joué un rôle politique et culturel dans le pays. Un quart des livrets d’opéra ont trait à l’antiquité romaine et l’opéra semble avoir eu une influence dans ce que Philipe Ayres appelle « Roman Self-Imaging », l’élaboration d’une image de soi comme Romain. Ayres n’englobe pas l’opéra italien parmi les arts qui ont illustré et défendu un état d’esprit fondé sur les deux piliers de la liberté et la vertu classiques, grâce auxquels les Britanniques se sont construits une image dérivée de la Rome républicaine et se sont façonnés en « oligarchie de vertu ». Cependant, il nous semble que les livrets d’opera seria italiens ont pu contribuer à ce processus en présentant des modèles avec lesquels les Britanniques ont pu s’identifier pour mieux les dépasser dans l’élaboration de leur image d’eux-mêmes en Romains.

    A partir de diálogos estabelecidos com o conceito de “função integrativa” da unidade linguística postulado por Émile Benveniste (1995 e com os conceitos de “noção” e “forma esquemática” postulados pela Teoria das Operações Enunciativas de Antoine Culioli (1990, sustentamos, neste artigo, que a identidade semântica da unidade linguística deve ser buscada no próprio desenrolar do processo enunciativo. Esses diálogos, ao estimularem uma ampla refl exão sobre o que vem a ser a matéria semântica da “palavra”, permitem, no abandono de toda estabilidade anterior à interação discursiva, avançar hipóteses sobre alguns dos temas que tanto interessam à aquisição de linguagem, em particular, à questão da produtividade da “palavra-frase” ou dos enunciados de um único termo que caracterizam os primeiros enunciados da criança. Permitem ainda mostrar, por meio da conceituação de “enunciado” como organização de “marcadores”, a criatividade enunciativa infantil relacionada à própria ausência de categorização gramatical prévia atribuída aos termos observados nas interações constitutivas da produção verbal da criança em seus primeiros enunciados.

    Full Text Available O objetivo principal desta pesquisa consiste em identificar as dimensões do modelo de negócios utilizando o Canvas Business Model, da empresa ALFA Combustíveis no Complexo Industrial Portuário de Suape/PE. O estudo é de natureza exploratória e foi desenvolvido mediante uma pesquisa de campo qualitativa. A coleta de dados ocorreu por meio de entrevistas semiestruturadas considerando como sujeitos de pesquisa profissionais desta distribuidora que atuam na base de operações do complexo de Suape/PE. E no tratamento, interpretação e análise dos resultados acerca dos dados coletados foi utilizada a técnica de categorização baseado em (Flores, 1994. Os resultados revelam que a empresa, no que diz respeito a oferta de valor, desenvolve ações para melhoria da eficiência na prestação do serviço. No que tange a infraestrutura, pessoas com expertise, atividades bem alinhadas e política de custos bem definidas são necessárias para o desenvolvimento deste tipo de negócio. E, no que se refere aos clientes, a segmentação em postos revendedores, o desenvolvimento de softwares que auxiliam no relacionamento com os clientes, projetos de entrega de produtos em tempo hábil e delimitação das fontes de receitas em função das atividades que são executadas na base configuram o modelo de negócio de uma distribuidora de combustíveis.

  12. Análise da aplicação de galerias técnicas em área integrante da operação urbana Água Branca, em São Paulo

    Directory of Open Access Journals (Sweden)

    Luis Henrique Lancellotti

    Full Text Available As redes que constituem os sistemas de infraestrutura urbana são, em geral, implantadas e geridas de forma isolada, sendo raramente consideradas em seu conjunto. Consequentemente, o espaço disponível no subsolo urbano tem sido reduzido, a ponto de congestionar e desorganizar sua ocupação. Nesse contexto, o presente artigo analisa e discute alternativas para a organização das redes de infraestrutura no subsolo urbano, considerando as galerias técnicas comparativamente às valas comuns. Galerias técnicas são túneis que reúnem as redes de vários serviços técnicos urbanos. A análise foi baseada na aplicação de parâmetros selecionados no caso da operação urbana Água Branca, área em desenvolvimento localizada no município de São Paulo. Os resultados mostram que as galerias técnicas representam, do ponto de vista físico e urbanístico, um meio estruturado para ocupação do subsolo e da superfície, caracterizando-se por uma alternativa eficiente, organizada e segura para a distribuição dos serviços técnicos urbanos. Do ponto de vista econômico, as galerias técnicas apresentam elevado custo inicial para implantação, o que as torna pouco viáveis quando analisadas somente sob esse critério. Em uma perspectiva de ciclo de vida, representam uma solução atraente, pelos menores custos operacionais e impactos envolvidos com a manutenção e a expansão de redes urbanas inseridas nos túneis de utilidades.

    Full Text Available O texto retoma a literatura crítica e múltipla que, a partir de diversas perspectivas teóricas, com ênfase em diferentes períodos históricos e países, trata das relações entre meios de comunicação de massa e representações das relações de gênero. Essa revisão bibliográfica seleciona trabalhos sugestivos para a discussão que se segue sobre as principais convenções das novelas brasileiras, gênero de programação que articula elementos do documentário e da ficção, tratando da nação em termos melodramáticos. Análise de títulos relevantes exibidos nos anos 70 e 80 sugere que novelas pautaram o espaço público brasileiro em termos que expandem o domínio convencionalmente definido como feminino.This paper revisits the literature on media and gender studies in search of works that help to discuss the case of Brazilian soap operas. A series of references coming from different theoretical perspectives, with emphasis in different countries and historical periods, bring up ideas and concepts that approach the contemporary desire to connect, to participate and to interact in terms conventionally associated to the female domain. Examples from specific soap operas suggest the ways in which these prime time daily soaps blend documentary and fiction conventions and treat the Brazilian nation in melodramatic terms. In doing so, soap operas have expanded what was conventionally treated as the female domain.

    Full Text Available A identificação e a análise de competências e recursos das operações é uma atividade que tem sido frequentemente negligenciada no processo de formulação da estratégia de produção. Reconhecendo a importância dessa atividade, este artigo apresenta uma metodologia que se propõe a incorporar a visão baseada em recursos na estratégia de operações de serviços. Para verificar sua aplicabilidade, a metodologia proposta foi testada em uma academia de ginástica, um típico sistema de operações de serviços que apresenta recursos e processos peculiares. A pesquisa de campo ocorreu segundo a abordagem da pesquisa-ação, na qual um dos autores deste artigo exerceu o papel de facilitador no processo de intervenção organizacional. Os resultados da aplicação sinalizaram para os gerentes da academia os recursos e as competências que deveriam ser priorizados para a manutenção da vantagem competitiva da empresa. Por outro lado, ficou claro para os pesquisadores que o modelo proposto era factível, fácil de usar e útil, além de cumprir seu papel de integrar a visão orientada pelo mercado com a visão baseada em recursos no complexo processo de formulação da estratégia de operações.The identification and analysis of competencies and resources in operations is an activity that has often been neglected in the process of operations strategy formulation. Recognizing the importance of this activity, this study presents a methodology that aims to incorporate the resource-based view in the service operations strategy.

    Full Text Available Can music express the world-view (Weltanschauung of a certain composer, or of a certain historical era – and how? In 19th Century, the wide-ranging philosophical implications of this question raised an intriguing quarrel between the formalists’ scepticism as to this point and their various opponents. Starting from the case study of the German psychologist and philosopher of music Georg Anschütz (1886-1953, it is argued that allowing for a systematic link of music and the world-views easily turns into the far more demanding (and occasionally ambiguous claim that music is the best and perhaps the only way to express them properly. In turn, this attitude sits well with the tendency to think of music hearing as a disembodied process, hinting at the deep dimension of synesthesia rather than to that of music as a cultural phenomenon, in Erich Hornbostel’s sense.

    Full Text Available O grande atrativo da Operação de Senning como descrita originalmente é a utilização das paredes do próprio átrio do paciente para a realização dos túneis venosos. A atrioseptostomia por balão, utilizada atualmente na grande maioria dos casos de transposição das grandes artérias (TGA, cria grandes comunicações interatriais. Com isso, é necessário a utilização de enxertos biológicos ou sintéticos (Dacron, Teflon e pericárdio bovino na septação do átrio esquerdo. Doze crianças consecutivas, com idades de 5 meses a 4 anos (média = 20 meses, foram submetidas à Operação de Senning com a utilização de tecidos do próprio paciente. O diagnóstico era de TGA em 9, TGA com comunicação interventricular (CIV em 1, TGA com estenose pulmonar valvar discreta em 1, TGA com justaposição das aurículas em 1 caso e todas as crianças foram submetidas à atrioseptostomia com balão no período neonatal. Em 5 casos foi utilizada a aurícula esquerda aberta e invertida para a septação interatrial, 1 com inversão e, em 5, inversão com abertura da aurícula esquerda e uso do próprio pericárdio in situ para a realização do túnel das veias pulmonares, devido às reduzidas dimensões do átrio direito (1 caso de justaposição das aurículas. O tempo de internação variou de 10 a 24 dias (média 15 dias, sendo que o período de pós-operatório variou de 7 a 22 dias (média 12 dias. Não houve óbitos no período de internação hospitalar. O seguimento no pós-operatório foi de 8 a 34 meses (média 23 meses e todos os pacientes apresentaram boa evolução clínica. O ecocardiograma realizado no período de internação e no seguimento pós-operatório não evidenciou sinais de obstrução ao fluxo nos túneis intracardíacos. O uso de tecidos do próprio paciente in situ, com potencial possibilidade de crescimento, resgata a vantagem principal da técnica originalmente descrita por Senning.One of the main theoretical

    Full Text Available OBJETIVO: Avaliar a morbidade e mortalidade após a operação de Jatene utilizando a dosagem de lactato sérico como principal marcador. MÉTODOS: Foi realizada uma coorte histórica com lactentes da UTI no período de 1995 a 2005 submetidos a essa cirurgia. Foram avaliados o lactato do pré-operatório, pós-operatório imediato (POI, da terceira hora de PO (3ªh, sexta hora (6ªh de PO e do 1º dia de PO; bem como outros fatores como sepse, sangramento aumentado, síndrome de baixo débito, insuficiência renal, hipertensão pulmonar, arritmias cardíacas, quilotórax, isquemia miocárdica, convulsões e outras complicações. Também foram coletadas informações referentes ao tempo de internação na UTI e ao desfecho (se o paciente morreu ou teve alta da UTI. RESULTADOS: A média de idade dos 76 pacientes foi de 14,59 ± 19,09 dias, peso ao nascimento de 3,128 ± 0,48 kg. Quarenta e quatro pacientes tinham o diagnóstico anatômico exclusivo de transposição de grandes artérias. O tempo médio de CEC foi de 143,78 ± 28,77 minutos, de pinçamento de 87,68 ± 22,3 minutos e de internação na UTI de 20,28 ± 15,62 dias. Vinte quatro (31,58% pacientes foram a óbito. O lactato aumentou no POI, retornando aos níveis basais em 24h. Os pacientes que foram a óbito apresentaram e mantiveram a partir do POI níveis de lactato mais elevados. O lactato da 3ªh foi o que melhor discriminou mortalidade, área sob a curva 0,68 (IC 0,54-0,83 P=0,035. Entretanto, considerando um ponto de corte para o lactato maior ou igual a 5,8 mmol/dl na 3ªh de PO, obteve-se apenas sensibilidade de 67% e especificidade de 64% para mortalidade. Existe correlação positiva entre o número de complicações e os níveis de lactato. A síndrome de baixo débito com odds ratio (OR de 7,67 (2,38-24, sangramento aumentado com OR de 2,91 (1,07-7,94 e complicações respiratórias com OR de 1,67 (1,35-2,05 são fatores de risco de óbito quando somados.

    Full Text Available OBJETIVO: Apresentar os resultados do tratamento da síndrome de hipoplasia do coração esquerdo (SHCE com técnica de Norwood modificada, na qual somente são usados tecidos autólogos para a reconstrução do arco aórtico. MÉTODO: De janeiro a dezembro de 2002, cinco recém-nascidos com idade variando de dois a nove dias (média 5,0 dias foram submetidos a operação de Norwood modificada. O diâmetro da aorta ascendente variou de 5 a 8 mm (média 6,2 mm. Foi empregada técnica na qual o arco aórtico e seus ramos foram amplamente dissecados, permitindo a reconstrução de um novo arco aórtico tendo a artéria pulmonar como via de saída, e com a utilização exclusiva de tecidos do próprio paciente. Anastomose sistêmico-pulmonar com politetrafluoretileno expandido de 3,0 mm foi utilizada em três pacientes e de 3,5 mm em dois pacientes. Todos foram operados com parada cardiocirculatória total. RESULTADOS: O tempo de parada cardiocirculatória variou de 41 a 60 minutos (média 52,8 minutos. Todas as crianças sobreviveram ao ato operatório e foram encaminhadas para a unidade de terapia intensiva com o esterno aberto. Ocorreu um óbito no 9: dia de pós-operatório por sepse, o que resultou numa taxa de sobrevivência imediata de 80%. Ocorreu um óbito tardio por pneumonia de aspiração aos dois meses. Uma criança foi submetida ao segundo estágio da operação (cavo pulmonar e encontra-se bem. Duas crianças estão em acompanhamento aguardando o próximo estágio.

    In questo intervento sono esaminati tre progetti architettonico-scultorei di Ivan Meštrović, nei quali è visibile la comprensione e l’applicazione della Gesamtkunstwerk, intesa come una forma particolare di partecipazione alla creazione artistica: il Tempio di Vidovdan, la Chiesa di Nostra Signora degli Angeli a Cavtat e la Chiesa del Santissimo Redentore a Otavice. Nell’articolo viene analizzato fino a che punto il protocollo della Gesamtkunstwerk sia veramente importante per l’interpretazione delle realizzazioni architettoniche di Meštrović. Inoltre, viene spiegato e dimostrato quanto Meštrović, come nessun altro artista del modernismo in Croazia, abbia riunito la progettazione architettonica e quella scultorea – fino ad allora quasi sempre scollegate – in un’unità artistica indissolubile, inserendole in seguito nello spettro di differenti e problematici contesti sociali, politici, religiosi o autoriflessivi. Nell’intervento, quindi, viene mostrato come la natura del protocollo della Gesamtkunstwerk cambi da un edificio impiegato per l’attivismo politico, prima e durante la prima guerra mondiale, fino ai luoghi sacrali e memoriali di natura più riflessiva, costruiti dopo la guerra e negli anni Venti. È importante rilevare come venga abbandonata l’interpretazione dell’«opera d’arte totale» come questione esclusivamente estetica, predeterminata dalla concezione dell’art pour l’art, e come a questa vengano aggiunte altre funzioni dell’opera nel suo più ampio contesto sociale, storico-politico e religioso.

    Full Text Available OBJETIVO: Descrever o desempenho gerencial de hospitais filantrópicos com operadoras de planos de saúde em comparação com o conjunto de hospitais filantrópicos no Brasil. MÉTODOS: Foram comparadas as estruturas gerenciais presentes nos hospitais filantrópicos com operadoras próprias de planos de saúde com aquelas observadas num conjunto representativo do setor hospitalar filantrópico, em seis dimensões: direção e planejamento, econômico-financeira, recursos humanos, serviços técnicos, serviços logísticos e tecnologia de informações. Consideraram-se os dados de uma amostra aleatória de 69 hospitais, extraída do setor hospitalar filantrópico, e 94 hospitais filantrópicos com operadoras próprias de planos de saúde. Nos dois casos incluíram-se apenas os hospitais com menos de 599 leitos. RESULTADOS: Foram identificados resultados mais positivos para o conjunto de hospitais com operadoras próprias de planos de saúde em todas as dimensões gerenciais comparadas. Em particular, destacaram-se as dimensões econômico-financeira e de tecnologia de informações, nas quais mais de 50% dos hospitais com operadoras apresentaram quase todas as condições consideradas. CONCLUSÕES: O setor hospitalar filantrópico é importante na prestação de serviços ao Sistema Único de Saúde. Os desafios para a sua manutenção e desenvolvimento impõem encontrar alternativas. O fomento de uma parceria público-privado neste segmento, por meio da operação de planos próprios ou prestação de serviços a outros planos de saúde convivendo com o SUS, constitui um campo que merece uma análise mais aprofundada.OBJECTIVE: To describe the management performance of philanthropic hospitals that operate their own health plans, in comparison with philanthropic hospitals as a whole in Brazil.

O experimento foi conduzido na Universidade Federal de Viçosa - UFV. O delineamento experimental foi em parcelas subdivididas com quatro tratamentos e nove repetições, totalizando 36 parcelas experimentais. Foram avaliadas a densidade do solo, teor de água do solo e resistência do solo a penetração, o consumo de combustível e o custo energético. O plantio direto foi o sistema que proporcionou menor consumo de combustível, seguido pelo sistema de cultivo mínimo com grade de disco leve, preparo reduzido e preparo convencional, respectivamente. O plantio direto teve um custo energético de 52,72% do custo do sistema convencional e o cultivo mínimo foi de 77,52%, possibilitando economizar entre 1216,51 e 578,39 MJ ha-1, respectivamente, equivalente a 25,45 e 12,10 L de óleo diesel para cada hectare trabalhado.This study was carried out to increase the efficiency of energy inputs used in tropical agriculture, so the energy cost (MJ ha-1 of the main mechanized agricultural operations was determined in four soil preparation systems for seeding of maize.

    2002-05-01

    Full Text Available Objetivo: deste estudo foi verificar os ajustes laríngeos realizados por cantores profissionais do gênero popular durante a imitação do canto em estilo lírico uma vez que muitas vezes ao ouvirmos um cantor popular interpretar uma música clássica percebemos que o mesmo faz modificações em sua qualidade vocal, tentando se aproximar, por imitação, do canto lírico. Forma de estudo: Clínico prospectivo. Material e método: Foram analisados 26 cantores profissionais do gênero popular, 10 homens e 16 mulheres, atuantes em baile. Foi aplicado questionário sobre perfil vocal, realizada análise perceptivo-auditiva e acústica das vozes e avaliação nasofibrolaringoscópica para análise da configuração laríngea nos estilos de canto popular e lírico. Resultado: A análise perceptivo-auditiva revelou que, ao cantar um trecho de música em estilo lírico, o cantor popular muda a qualidade vocal, aumentando o vibrato, o volume vocal, melhorando a ressonância vocal e sobrearticulando mais as palavras. Na análise espectrográfica não foi observada a ocorrência do formante do cantor em nenhuma das vozes. O ajuste laríngeo realizado por cantores populares ao imitarem o estilo de canto lírico foi predominantemente o aumento das constrições ântero-posterior e mediana sendo que a constrição mediana ocorreu mais no sexo masculino. Os valores de jitter e shimmer reduziram significantemente na vogal cantada em relação à vogal falada nas vozes femininas.Aim: The aim of this study was to check over laryngeal arrangement used by professional singers of pop music. This idea came from the fact that many times we notice vocal quality changes when we hear pop singers trying to sing opera music. Study design: Clinical prospective. Material and method: A number of 26 subjects was analyzed, 10 males and 16 females, all of them were pop professional singers that worked in dancing shows.

    Full Text Available Este artigo analisou a produção científica em gestão de operações no Brasil, procurando identificar as temáticas de maior interesse dos pesquisadores e os grupos de pesquisa mais atuantes a partir de uma amostra de 3.224 artigos publicados em 13 periódicos científicos nacionais, no período de 2001 a 2010. Além da classificação dos artigos conforme suas categorias temáticas, também se identificou a origem dos autores, que foram separados em função da área de atuação (Administração ou Engenharia de Produção e da instituição de afiliação. De maneira geral, 18,4% de todos os 3.224 artigos publicados nas revistas analisadas se enquadram como pertinentes à área de Gestão de Operações. Os resultados apontam sensível diferença entre os percentuais referentes a revistas com origem na área de Administração, que variaram de 1,7% a 10,9%, e os relacionados às revistas com origem na área da Engenharia de Produção, cujos percentuais variaram de 57,8% a 62,4%. O tema mais abordado de Gestão de Operações foi logística e cadeia de suprimentos, com aproximadamente 20% dos trabalhos publicados. Esse tema tem merecido mais destaque nas revistas de Administração, com 35% do total de trabalhos publicados, do que nas revistas de Engenharia de Produção, em que totaliza 14% dos trabalhos publicados. Os temas operações de serviços e gestão de projetos/ desenvolvimento de produtos ocupam praticamente juntos a mesma posição, em segundo lugar entre os temas de maior interesse, tanto nas revistas de Administração como nas de Engenharia de Produção. Percebe-se também que os assuntos relacionados ao tema ergonomia e organização do trabalho são pouco abordados pelas revistas de Administração, com uma média de 2% dos trabalhos publicados. No entanto, representam 8% dos trabalhos publicados nas revistas de Engenharia de Produção. Acredita-se que a pesquisa tenha sido útil, dentre outros motivos, para que os

    The LVD time stability allows to establish a time-shift in the OPERA experiment, thus providing the first proof against Superluminal neutrinos, using the horizontal muons of the "Teramo Anomaly". This proof is particularly interesting since does not need the knowledge of the distance between the place where the neutrinos are produced (CERN) and the place where they are detected (LNGS). Since the Superluminal neutrinos generated in the physics community a vivid interest in good and bad behaviour in physics research, the author thought it was appropriate to recall the origin of the Gran Sasso Lab, of the 3rd neutrino, of the horizontal muons due to the "Teramo Anomaly" and of the oscillation between leptonic flavours, when the CERN-Gran Sasso neutrino beam was included in the project for the most powerful underground Laboratory in the world.

    Full Text Available RACIONAL: Atualmente cerca de 90% das operações anorretais podem ser realizadas em regime ambulatorial. A técnica anestésica é fator fundamental na busca de menor tempo de internamento e redução de custos nestes procedimentos. Não há consenso na literatura sobre qual o melhor tipo de anestesia para essas operações. OBJETIVO: Comparar os custos da técnica de raquianestesia com bupivacaína 0,5% isobárica com a técnica de anestesia venosa com propofol associada ao bloqueio perianal local com lidocaína a 2% e bupivacaína 0,5% (anestesia combinada em pacientes submetidos a operações anorretais. MÉTODOS: Foram analisados dados de 99 pacientes submetidos à operações anorretais, divididos em dois grupos: grupo I (raquianestesia, composto por 50 pacientes e grupo II (anestesia combinada, composto por 49 pacientes. Foram estudados os procedimentos cirúrgicos, tempo de procedimento anestésico-cirúrgico, tempo de internamento e custos globais de cada paciente. RESULTADOS: Não houve diferença estatística significativa entre os grupos estudados em relação ao tipo de procedimento cirúrgico, sexo, idade e complicações. O tempo médio do procedimento anestésico-cirúrgico, no grupo I foi de 53,1 minutos e de 44,08 minutos no grupo II (P=0,034.

    Full Text Available Cet article revient sur la notion de sentimentalité et particulièrement sur l’opéra sentimental qui dérive du roman anglais de même nature. L’idée du triomphe ultime du bien, de la possibilité pour une jeune fille pauvre mais honnête de réussir dans la vie et de la bonté comme lien inaltérable unissant les hommes acquit une telle force à la fin du XVIIIe siècle qu’elle a été utilisée pour la définir. Une des œuvres les plus significatives du style sentimental, Pamela, le roman de Richardson, retint l’attention du librettiste Isaac Bickerstaffe (1733-1808, qui le transforma en « opéra anglais » faisant remarquer que son œuvre, « une bagatelle à bien des points de vue, constituait la première pièce sentimentale qui paraisse sur la scène anglaise depuis 40 ans ». Mis en musique par Samuel Arnold (1740-1802 l’opéra présente un genre nouveau, « l’opéra pastiche », qui incorpore la musique de plusieurs compositeurs. Musicalement, l’opéra n’a rien de très original et selon nos critères actuels, l’absence d’un seul compositeur nettement identifiable ou d’une esthétique de composition particulière en fait un objet d’art difficile à jauger. Mais la simplicité de  la musique elle-même constitue un attribut essentiel qui permet à la sentimentalité de l’histoire de s’exprimer et annonce véritablement la naissance d’un nouveau genre d’opéra anglais, le pastiche. De même, les caractéristiques très particulières des représentations théâtrales en Angleterre ont joué un rôle déterminant dans le développement de l’opéra sentimental à Londres.This article returns to the well-known notion of sentimental culture, and specifically, to sentimental opera derived from the English novel.  The notion that goodness must triumph, that a poor but honest girl should ‘make good’, and that such goodness should form a binding force between humans, was such a strong force in

    controle de qualidade são necessários em nível de beneficiamento. O objetivo deste trabalho foi desenvolver um método para caracterizar a eficiência da tipificação e da classificação por tamanho. Durante a safra de 1998 cinco locais de beneficiamento do Vale Bonaerense do Rio Colorado (Província de Buenos Aires, Argentina foram escolhidos ao acaso. Em todos eles, as variáveis medidas foram a largura da mesa de classificação, as velocidades de deslocamento e de rotação dos bulbos e também o número de bulbos/operário/hora. Antes e depois da classificação, amostras de 100 bulbos de cada tamanho foram escolhidas ao acaso, avaliadas e medidos seus diâmetros. A eficiência de classificação por tamanho foi determinada e o teste Qui-quadrado foi aplicado para comparar a freqüência de defeitos observada com aquela esperada dentro de cada categoria. Todas as packinghouses falharam em atingir os limites de defeitos preestabelecidos e somente uma delas atingiu as normas básicas da categoria classe Extra. Ainda, quando os equipamentos e o esquema operacional foram diferentes entre os locais de beneficiamento, o fluxo operacional (bulbos/operário/hora foi similar entre eles. Diferenças na performance de classificação podem ser atribuídas principalmente à seqüência de operações e à velocidade das correias de transporte. O equipamento e sua calibração afetou a classificação por tamanho, com os melhores resultados obtidos com o sistema de rolos divergentes. A metodologia proposta para caracterizar a eficiência pode ser considerada como uma ferramenta simples e útil para monitorar a qualidade das packinghouses de cebola.

Um paciente foi submetido ao 2º tempo da operação, tunelizando a veia cava inferior (VCI para a APD, com sucesso. A avaliação do fluxo da derivação cavo-pulmonar bidirecional está sendo realizada pela ecodopplercardiografia e ressonância nuclear magnética e a perfusão pulmonar mediante cintilografia radioisotópica. A indicação do 2º tempo da operação obedece à própria evolução clínica e avaliação da saturação arterial durante a cicioergometria. A derivação cavo-pulmonar bidirecional permite uma adaptação progressiva do fluxo venoso para o pulmão, diminuindo a sobrecarga de volume do ventrículo, preparando o paciente para a derivação venosa total.From March 1990 to January 1994, 17

    Full Text Available Abstract - The vertical cemetery is a one or more pavement building equipped with compartments destined for burials, named locusts. This typology of cemetery is an tendency in the United States, Europe and Japan, and it has currently expanded in Brazil. Even so, publication of scientific work about this topic has been minimal, especially when it comes to environmental impact. Therefore, this present article’s objective is to analyze and classify the environmental impact derived from the vertical cemetery’s implementation phase and operation, utilizing a hypothetical situation. The methodology was based on the environmental impact templates, contemplating physical, biological and social-economical eeans. In turn, the environmental impacts arising from the operation phase are variable, and the largest magnitude that is related to the change in air quality through emissions from the decomposition of the bodies. Moreover, this hypothetical situation identified 17 environmental impacts of direct incidence, which 08 occur during the implementation phase and 09 during the operation phase; 03 will be of a positive nature and 14 negative; 12 are likely to real event and 05 only potential; 10 will be reversible and 7, at moment, will be irreversible. = Resumo - O cemitério vertical é um edifício de um ou mais pavimentos dotados de compartimentos destinados a sepultamentos, denominados de lóculos.
