    Vocal fold hemorrhage can represent a disastrous and potentially career ending injury to a singer or professional voice user. The risk factors of vocal fold hemorrhage, including laryngeal trauma, phonotrauma, aspirin and nonsteroidal antiinflammatories, and hormonal imbalances are well known. We present a case of an opera singer who developed recurrent vocal fold hemorrhage associated with coumadin anticoagulation therapy. This case highlights the importance of the risk of vocal fold hemorrhage to professional singers and professional voice users and offers an alternative to long-term coumadin therapy in this select population.

    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.

    Solo singers have been shown to over estimate the relative sound pressure level of a delayed, external reproduction of their own voice, singing single syllables, which, in turn, appears to influence the preferred delay of simulated stage reflections [Noson, Ph.D. thesis, Kobe University, 2003]. Bone conduction is thought to be one factor separating singer versus instrumental performer judgments of stage acoustics. Using a parameter derived from the vocal signal autocorrelation function (ACF envelope), the changes in singer preference for delayed reflections is primarily explained by the ACF parameter, rather than internal bone conduction. An auditory model of a singer's preferred reflection delay is proposed, combining the effects of acoustical environment (reflection amplitude), bone conduction, and performer vocal overestimate, which may be applied to the acoustic design of reflecting elements in both upstage and forestage environments of opera stages. For example, soloists who characteristically underestimate external voice levels (or overestimate their own voice) should be provided shorter distances to reflective panels-irrespective of their singing style. Adjustable elements can be deployed to adapt opera houses intended for bel canto style performances to other styles. Additional examples will also be discussed. a)Now at Kumamoto Univ., Kumamoto, Japan. b)Now at: 1-10-27 Yamano Kami, Kumamoto, Japan.

  4. The singer's voice range profile: female professional opera soloists.

    2010-07-01

    This work concerns the collection of 30 voice range profiles (VRPs) of female operatic voice. We address the questions: Is there a need for a singer's protocol in VRP acquisition? Are physiological measurements sufficient or should the measurement of performance capabilities also be included? Can we address the female singing voice in general or is there a case for categorizing voices when studying phonetographic data? Subjects performed a series of structured tasks involving both standard speech voice protocols and additional singing tasks. Singers also completed an extensive questionnaire. Physiological VRPs differ from performance VRPs. Two new VRP metrics, the voice area above a defined level threshold and the dynamic range independent from the fundamental frequency (F(0)), were found to be useful in the analysis of singer VRPs. Task design had no effect on performance VRP outcomes. Voice category differences were mainly attributable to phonation frequency-based information. Results support the clinical importance of addressing the vocal instrument as it is used in performance. Equally important is the elaboration of a protocol suitable for the singing voice. The given context and instructions can be more important than task design for performance VRPs. Yet, for physiological VRP recordings, task design remains critical. Both types of VRPs are suggested for a singer's voice evaluation. Copyright (c) 2010 The Voice Foundation. Published by Mosby, Inc. All rights reserved.

    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.

    To compare the voice handicap index of popular and erudite professional singers according to gender, age, professional experience time, and presence or absence of self-reported vocal complaints. One hundred thirty-two professional singers, 74 popular and 58 erudite, who responded to a questionnaire with regards to identification, age, gender, professional experience time in singing, musical genres (for popular singers), vocal classification (for erudite singers), presence of self-reported vocal complaints, and the specific protocols for popular (Modern Singing Handicap Index - MSHI) and erudite (Classical Singing Handicap Index - CSHI) singing. Higher proportion of women and higher incidence of vocal complaints were observed in the popular singers compared with the erudite singers. Most of the popular singers belonged to the genre of Brazilian Popular Music. Regarding the classification of erudite singers, there was greater participation of sopranos and tenors. No statistical differences were observed with respect to age and professional experience time between the groups. Comparison of the MSHI and CSHI scores showed no statistically significant difference between these scores and genre or age in both groups of singers. Professional experience time was related to the total score and the subscales disability and impairment in the MSHI, only for popular singers with vocal complaints. There was no correlation between these variables and the CSHI for erudite singers. The impact of vocal difficulty/problem interferes differently in these two musical genres when related to vocal complaint and professional experience time. The MSHI and CSHI protocols proved to be important tools not only for the identification of problems, but also for the understanding of how these individuals relate their voices with this occupational activity.

    Opera and chant singers learn to effectively use aerodynamic components by breathing exercises during their education. Aerodynamic components, including subglottic air pressure and airflow, deteriorate in voice disorders. This study aimed to evaluate the changes in aerodynamic parameters and supraglottic structures of men and women with different vocal registers who are in an opera and chant education program. Vocal acoustic characteristics, aerodynamic components, and supraglottic structures were evaluated in 40 opera and chant art branch students. The majority of female students were sopranos, and the male students were baritone or tenor vocalists. The acoustic analyses revealed that the mean fundamental frequency was 152.33 Hz in the males and 218.77 Hz in the females. The estimated mean subglottal pressures were similar in females (14.99 cmH 2 O) and in males (14.48 cmH 2 O). Estimated mean airflow rates were also similar in both groups. The supraglottic structure compression analyses revealed partial anterior-posterior compressions in 2 tenors and 2 sopranos, and false vocal fold compression in 2 sopranos. Opera music is sung in high-pitched sounds. Attempts to sing high-pitched notes and frequently using register transitions overstrain the vocal structures. This intense muscular effort eventually traumatizes the vocal structures and causes supraglottic activity. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

    The respiratory system is a central part of voice production, but details in breath control during phonation are not yet fully understood. This study therefore aims to investigate regional ventilation of the lungs during phonation. It was analyzed in 11 professional singers using electrical impedance tomography during breathing and phonation with maximum phonation time. Our results show differences in impedance changes between phonation and exhalation in the courses of time and amplitude normalized curves. Furthermore, differences related to gender and professionalism were found in the temporal and spatial profiles of regional ventilation. For female singers (sopranos and mezzo-sopranos) the anterior region participated less at the start of ventilation, and was more stable at the midpoint compared to male singers (tenors). This might be an expression of a smaller relative movement in rib cage and anterior diaphragm, primarily in early phonation. Copyright © 2017 Elsevier B.V. All rights reserved.

    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.

    The field of music is increasingly gaining scope and attracting researchers from varied fields in terms of improvising the art of voice modulation in singing. There has been a lot of competition, and young budding singers are emerging with more talent. This study is aimed to develop software to differentiate a prepubertal voice as that of a singer or a non-singer using an objective tool-singing power ratio (SPR)-as an objective measure to quantify the resonant voice quality. Recordings of singing and phonation were obtained from 30 singers and 30 non-singer girls (8-10 years). Three professional singers perceptually evaluated all samples using a rating scale and categorized them as singers or non-singers. Using Matlab, a program was developed to automatically calculate the SPR of a particular sample and classify it into either of two groups based on the normative values of SPR developed manually. Positive correlation for SPR of phonation or singing was found between perceptual and manual ratings, and objective values of SPR. Software could automatically give the SPR values for samples that are fed and could further differentiate them as singer or non-singer. Researchers need not depend on professional singers or musicians for the judgment of voice for research purposes. This software uses an objective tool, which serves as an instrument to judge singing talent using singing and phonation samples of children. Also, it can be used as a first line of judgment in any singing audition process, which could ease the work of professionals. Copyright © 2017 The Voice Foundation. All rights reserved.

    To multidimensionally investigate common vocal effects in experienced professional nonclassical singers, to examine their mechanism of production and reproducibility, to demonstrate the existence of partial glottal vibration, and to assess the potential of damage to the voice from nonclassical singing. Individual cohort study. Ten male singers aged between 25 and 46 years (34 ± 7 years [mean ± SD]) with different stylistic backgrounds were recruited (five pop/rock/metal, five musical theater). Participants repeatedly presented the usual nonclassical vocal effects and techniques in their repertoire. All performances were documented and analyzed using established instruments (eg, auditory-perceptual assessment, videolaryngostroboscopy, electroglottography, voice function diagnostics). The vocal apparatus of all singers was healthy and capable of high performance. Typical nonclassical vocal effects were breathy voice, creaky voice, vocal fry, grunting, distortion, rattle, belt, and twang. All effects could be easily differentiated from each other. They were intraindividually consistently repeatable and also interindividually produced in a similar manner. A special feature in one singer was the first evidence of partial glottal vibration when belting in the high register. The unintended transition to this reduced voice quality was accompanied by physical fatigue and inflexible respiratory support. The long-lasting use of the investigated nonclassical vocal effects had no negative impact on trained singers. The possibility of long-term damage depends on the individual constitution, specific use, duration, and extent of the hyperfunction. The incidence of partial glottal vibration and its consequences require continuing research to learn more about efficient and healthy vocal function in nonclassical singing.

    The obvious perceptual differences between various singing styles like Western operatic and jazz rely on specific dissimilarities in vocal technique. The present study focuses on differences in vibrato acoustics and in singer's formant as analyzed by a novel software tool, named BioVoice, based on robust high-resolution and adaptive techniques that have proven its validity on synthetic voice signals. A total of 48 professional singers were investigated (29 females; 19 males; 29 Western operatic; and 19 jazz). They were asked to sing "a cappella," but with artistic expression, a well-known musical phrase from Gershwin's Porgy and Bess, in their own style: either operatic or jazz. A specific sustained note was extracted for detailed vibrato analysis. Beside rate (s(-1)) and extent (cents), duration (seconds) and regularity were computed. Two new concepts are introduced: vibrato jitter and vibrato shimmer, by analogy with the traditional jitter and shimmer of voice signals. For the singer's formant, on the same sustained tone, the ratio of the acoustic energy in formants 1-2 to the energy in formants 3, 4, and 5 was automatically computed, providing a quality ratio (QR). Vibrato rates did not differ among groups. Extent was significantly larger in operatic singers, particularly females. Vibrato jitter and vibrato shimmer were significantly smaller in operatic singers. Duration of vibrato was also significantly longer in operatic singers. QR was significantly lower in male operatic singers. Some vibrato characteristics (extent, regularity, and duration) very clearly differentiate the Western operatic singing style from the jazz singing style. The singer's formant is typical of male operatic singers. The new software tool is well suited to provide useful feedback in a pedagogical context. Copyright © 2015 The Voice Foundation.

    Biofeedback therapy is a learning process that is based on "operant conditioning" techniques. To estimate the significance of biofeedback to an accurate and faster control of singing voice emission. Significantly, it was discovered that professional singers active in performing of both classical and music theatre repertoire with regard to the visual-kinesthetic effect of melodic contour in musical notation as it affect vocal timbre. The results of the study also indicate that the development of new technology for youth singer vocal training, may be useful to these singers.

  16. The Bracale Opera Company in Colombia (1922-1933: a music culture agent for the country

    Full Text Available The opera company of Adolfo Bracale visited Colombia several times between 1922 and 1933. This opera company made contributions to the musical environment of that period. It brought opera singers, orchestral members and conductors internationally recognized at the time, and incorporated repertoire not heard before in Colombia. The musical environment of the country was also enriched by the mobilization of a series of cultural, social and commercial factors that had to do with these opera seasons. The last performance of the Bracale opera company took place in Medellín in 1933, some months before it went bankrupt. Because of this, some of its musicians, including Bracale, decided to stay in the country, and thus they contributed to the formation of musicians and orchestras that made part of the musical culture of the moment and of generations to come.

  17. A scale value for the balance between stage and pit and inside an historical opera house

    2004-05-01

    Despite its recognized importance, the balance between the singer and the orchestra inside an opera house has received minor attention in the past. In fact, after the fundamental work of Meyer [J. Meyer, ``Some problems of opera house acoustics,'' Proceedings of 12th I.C.A., Vancouver, 1986, pp. 13-18], who explained why the solo singing voice can compete with the orchestra, only partial results were reported on this perceived attribute. In this work a reference scale to assess the balance inside an historical opera house is achieved by means of listening tests inside a controlled room. Two scaling experiments were performed based on the acoustical data measured inside an historical opera house, the Teatro Comunale di Ferrara, Italy. By doing so all of the relevant acoustical characteristics of a typical Italian-style opera house could be exactly reproduced. Acceptable values do not differ much in the stalls and in the boxes and are within 2 dB(A) to +2.3 dB(A). The transfer of the findings to other types of opera houses is discussed, too.

    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.

    To clarify the relationship of the sound fields between the stage and the orchestra pit, we conducted acoustical measurements in a typical historical opera house, the Teatro Comunale of Ferrara, Italy. Orthogonal factors based on the theory of subjective preference and other related factors were analyzed. First, the sound fields for a singer on the stage in relation to the musicians in the pit were analyzed. And then, the sound fields for performers in the pit in relation to the singers on the stage were considered. Because physical factors vary depending on the location of the sound source, performers can move on the stage or in the pit to find the preferred sound field.

    2005-09-01

    Studies of acoustical balance between singers within a choir by means of room acoustical measurements have shown that the directional sound propagation of the source is important. For this reason the directivity of female and male singers for different vowels has been measured in this investigation. Measurements of a pilot study and some first measurements in 1998 have been supplemented with new measurements and an enhanced setup. A special measurement setup with reference and recording microphones was used to collect the directivity data. A resolution of 10 deg for azimuth and elevation angle was obtained. The results will be shown in 3D spherical plots with frequency adjustments in semitones from 80 to 8000 Hz. The measurements are compared to an artificial singer's directivity, and the influence of a sheet music binder in front of a singer will be shown. The results give information on the directivity of singers and are relevant for the prediction of self-to-other-ratios that result from placement and formation aspects within a choir.

  1. Breathing and Singing: Objective Characterization of Breathing Patterns in Classical Singers.

    2016-01-01

    Singing involves distinct respiratory kinematics (i.e. movements of rib cage and abdomen) to quiet breathing because of different demands on the respiratory system. Professional classical singers often advocate for the advantages of an active control of the abdomen on singing performance. This is presumed to prevent shortening of the diaphragm, elevate the rib cage, and thus promote efficient generation of subglottal pressure during phonation. However, few studies have investigated these patterns quantitatively and inter-subject variability has hindered the identification of stereotypical patterns of respiratory kinematics. Here, seven professional classical singers and four untrained individuals were assessed during quiet breathing, and when singing both a standard song and a piece of choice. Several parameters were extracted from respiratory kinematics and airflow, and principal component analysis was used to identify typical patterns of respiratory kinematics. No group differences were observed during quiet breathing. During singing, both groups adapted to rhythmical constraints with decreased time of inspiration and increased peak airflow. In contrast to untrained individuals, classical singers used greater percentage of abdominal contribution to lung volume during singing and greater asynchrony between movements of rib cage and abdomen. Classical singers substantially altered the coordination of rib cage and abdomen during singing from that used for quiet breathing. Despite variations between participants, principal component analysis revealed consistent pre-phonatory inward movements of the abdominal wall during singing. This contrasted with untrained individuals, who demonstrated synchronous respiratory movements during all tasks. The inward abdominal movements observed in classical singers elevates intra-abdominal pressure and may increase the length and the pressure-generating capacity of rib cage expiratory muscles for potential improvements in voice

    This pilot study aimed to evaluate the internal consistency, convergent construct validity and criterion validity of Arabic version of the Vocal Tract Discomfort Scale (VTDS), and to investigate the correlation between the scores of the VTDS, the VHI and the acoustic measures of fundamental frequency (F0), shimmer, jitter and signal-to-noise ratio (SNR). A cross-sectional study where 97 participants participated (47 males and 50 females) (mean age 20.5 ± 2.1 years) (31 student singers and 66 other non-professional voice user students). Participants were without self-perceived voice disorders who completed the VTDS-Arab scale and the Voice Handicap Index (VHI-Arab), and recorded a vocal sample of/a:/at a comfortable level. A positive internal consistency that signifies reliability was confirmed by Cronbach's α = .884 and 0.874 for the VTDS-Arab frequency and severity subscales, respectively. A moderate positive correlation was found between the VTDS-Arab (frequency, severity, total) and the VHI-Arab total where values of Pearson's correlation coefficient were r= 0.459, 0.430 and 0.451, respectively. Weak correlations were found between all of the acoustic measures and the scores of the VTDS-Arab and VHI-Arab (total and subscales). The area under curve for the VTDS was AUC= 0.824, 0.804 and 0.817 for the VTDS frequency, VTDS severity and VTDS total, respectively. The VTDS-Arab is a valid and reliable tool in measuring vocal tract sensations and predicting the perception of vocal handicap in student singers and can be used to predict the vocal load among professional voice users.

  4. The Kadison-Singer property

    Stevens, Marco

    2016-01-01

    This book gives a complete classification of all algebras with the Kadison-Singer property, when restricting to separable Hilbert spaces. The Kadison-Singer property deals with the following question: given a Hilbert space H and an abelian unital C*-subalgebra A of B(H), does every pure state on A extend uniquely to a pure state on B(H)? This question has deep connections to fundamental aspects of quantum physics, as is explained in the foreword by Klaas Landsman. The book starts with an accessible introduction to the concept of states and continues with a detailed proof of the classification of maximal Abelian von Neumann algebras, a very explicit construction of the Stone-Cech compactification and an account of the recent proof of the Kadison-Singer problem. At the end accessible appendices provide the necessary background material. This elementary account of the Kadison-Singer conjecture is very well-suited for graduate students interested in operator algebras and states, researchers who are non-specialist...

  5. Singers' and Nonsingers' Perception of Vocal Vibrato.

    2015-09-01

    Vibrato, a small, nevertheless an important component in the singing voice is known to enrich the overall singing voice quality. However, in the perception of overall performance, it is often neglected. Singing performance is often appreciated by a mixed audience of those who love music, but not necessarily sing and other singers who may or may not be teachers of singing. The objectives of the present study were aimed at investigating singers' and nonsingers' perception of vocal vibrato and its effect on the ratings of singer's overall performance. Prerecorded audio samples of the chorus of a hymn (How Great Thou Art) as sung by 10 singers (both men and women) were played via a speaker to two groups of judges which consisted of three experienced singers and three experienced nonsingers. The singer judges (SJs) were vocal instructors in Western classical, music theater, pop, and contemporary styles. Seven parameters (presence of vibrato, rate, extent, conspicuousness, quality, periodicity, and type) related to vibrato were evaluated through auditory perception by these two groups of judges on a rating scale developed specifically for the study, and one parameter evaluated singer's overall performance. Cohen's Kappa statistical analysis was used for inter-rater reliability within groups. Nonsinger judges (NSJs) within the group showed varied ratings as did SJs, yet SJs did have higher agreement than NSJs. Chi-square analysis was used across groups. Both groups were distinct from each other in their perception of vibrato. Ratings of singer's overall performance were not affected for NSJs, but certainly affected for SJ. It could not be concluded that ratings on singer's overall performance was affected as a result of vibrato. Since vibrato is often over-ridden by the singer's voice. But a rare occasion can arise where a vibrato may not sound pleasant and can affect the listener's perception of the singer's performance. Often a feedback from listeners would help monitor

    We describe the psychophysical features of vocal amusia in a professional tango singer caused by an infarction mainly involving the superior temporal cortex of the right hemisphere. The lesion also extended to the supramarginal gyrus, the posterior aspect of the postcentral gyrus and the posterior insula. She presented with impairment of musical perception that was especially pronounced in discriminating timbre and loudness but also in discriminating pitch, and a severely impaired ability to reproduce the pitch just presented. In contrast, language and motor disturbances were almost entirely absent. By comparing her pre- and post-stroke singing, we were able to show that her singing after the stroke lacked the fine control of the subtle stress and pitch changes that characterized her pre-stroke singing. Such impairment could not be explained by the impairment of pitch perception. The findings suggest that damage to the right temporoparietal cortex is enough to produce both perceptive and expressive deficits in music.

    It is acknowledged generally that professional contemporary commercial music (CCM) singers engage in supplementary employment ("the day job") to achieve and maintain a reliable living wage. In this paper, consideration is given to the impact of such nonperformance employment on CCM's sustainable vocal health. Collected data from a survey of 102 professional contemporary gig singers were analysed using descriptive statistical procedures from the Statistical Package for the Social Sciences. Although these data provided descriptions of the personal characteristics of individuals in the sample, the inclusion of open format questions encouraged participants to report details of their "lived" experience. Additionally, a meta-analysis of a range of associated literature was undertaken. Sixty-five participants (N = 102) reported that in addition to their heavy performance voice use, they were employed in "other" work (the "day job") where their speaking voice loads were high. In responding to open-ended questions, many proffered written comments that were unprompted. The collected data from this element of the research study are reported here. We propose that at least some causal factors of singers' reported voice problems may lie in the misuse or overuse of their everyday speaking voice (as demanded by their "day job") rather than a misuse of their singing voice. These findings have practical application to all whose concern is care for the vocal or emotional health and performance longevity of professional singers. Copyright © 2017 The Voice Foundation.

    vocal behavior of popular singers, according to gender and professional and amateur categories. METHOD: interview with 47 singers, 25 men and 22 women. RESULTS: there were statistical significance differences in the following findings: MALE - microphone during rehearsal, absence of diagnosed voice problems, lack of assistance on vocal hygiene, pain or discomfort after singing, but no allergies or respiratory problems; FEMALES - singing lessons and awareness of posture; AMATEUR - no dancing while singing, no imitating voices, lack of otolaryngological evaluation (ENT, no diagnosed vocal problems, lack of speech-language therapy, absence of guidelines on vocal anatomy/physiology and without alcohol consumption during the rehearsals; PROFESSIONAL- hoarseness, knowledge about articulation, alcohol consumption during performance, excess throat clearing, pain after singing. CONCLUSIONS: the comparison between genders showed male singers were using microphone in rehearsals, did not have respiratory or allergic problems, nor voice problems were diagnosed, but they had pain sensation or discomfort after singing and did not have vocal hygiene, and female singers had singing lessons and followed posture guidelines. The comparison between amateurs and professionals showed that amateur singers did not dance while singing, did not imitate voices, did not consume alcohol during rehearsals, and did not have diagnosed voice problems, but they did not have ENT evaluation, nor did they engage in speech-language therapy, and had no awareness of vocal anatomy/physiology; and the professional singers complained of hoarseness, excess throat clearing and pain after singing, and they consumed alcohol during singing, despite having knowledge about articulation.

    The American musical theatre industry is a multibillion dollar business in which the requirements for singers are varied and complex. This study identifies the musical genres and voice requirements that are currently most requested at professional auditions to help voice teachers, pedagogues, and physicians who work with musical theatre singers understand the demands of their clients' business. Frequency count. One thousand two thirty-eight professional musical theatre audition listings were gathered over a 6-month period, and information from each listing was categorized and entered into a spreadsheet for analysis. The results indicate that four main genres of music were requested over a wide variety of styles, with more than half of auditions requesting genre categories that may not be served by traditional or classical voice technique alone. To adequately prepare young musical theatre performers for the current job market and keep the performers healthily making the sounds required by the industry, new singing styles may need to be studied and integrated into voice training that only teaches classical styles.

  11. Backstage at OPERA

    CERN Multimedia

    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...

  12. Predicted singers' vocal fold lengths and voice classification-a study of x-ray morphological measures.

    2009-07-01

    Students admitted to the solo singing education at the University of Music Dresden, Germany have been submitted to a detailed physical examination of a variety of factors with relevance to voice function since 1959. In the years 1959-1991, this scheme of examinations included X-ray profiles of the singers' vocal tracts. This material of 132 X-rays of voice professionals was used to investigate different laryngeal morphological measures and their relation to vocal fold length. Further, the study aimed to investigate if there are consistent anatomical differences between singers of different voice classifications. The study design used was a retrospective analysis. Vocal fold length could be measured in 29 of these singer subjects directly. These data showed a strong correlation with the anterior-posterior diameter of the subglottis and the trachea as well as with the distance from the anterior contour of the thyroid cartilage to the anterior contour of the spine. These relations were used in an attempt to predict the 132 singers' vocal fold lengths. The results revealed a clear covariation between predicted vocal fold length and voice classification. Anterior-posterior subglottic-tracheal diameter yielded mean vocal fold lengths of 14.9, 16.0, 16.6, 18.4, 19.5, and 20.9mm for sopranos, mezzo-sopranos, altos, tenors, baritones, and basses, respectively. The data support the assumption that there are consistent anatomical laryngeal differences between singers of different voice classifications, which are of relevance to pitch range and timbre of the voice.

  13. OPERA's overture

    CERN Multimedia

    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...

    Fadel, Congeta Bruniere Xavier; Dassie-Leite, Ana Paula; Santos, Rosane Sampaio; Santos, Celso Gonçalves Dos; Dias, Cláudio Antônio Sorondo; Sartori, Denise Jussara

    The purpose of this study was to analyze the immediate effects of the semi-occluded vocal tract exercise (SOVTE) using the LaxVox® tube in singers. Participants were 23 singers, classical singing students, aged 18 to 47 years (mean age = 27.2 years). First, data was collected through the application of a demographic questionnaire and the recording of sustained emission - vowel /ε/, counting 1-10, and a music section from the participants' current repertoire. After that, the participants were instructed and performed the SOVTE using the LaxVox® tube for three minutes. Finally, the same vocal samples were collected immediately after SOVTE performance and the singers responded to a questionnaire on their perception regarding vocal changes after the exercise. The vocal samples were analyzed by referees (speech-language pathologists and singing teachers) and by means of acoustic analysis. Most of the singers reported improved voice post-exercise in both tasks - speech and singing. Regarding the perceptual assessment (sustained vowel, speech, and singing), the referees found no difference between pre- and post-exercise emissions. The acoustic analysis of the sustained vowel showed increased Fundamental Frequency (F0) and reduction of the Glottal to Noise Excitation (GNE) ratio post-exercise. The semi-occluded vocal tract exercise with LaxVox® tube promotes immediate positive effects on the self-assessment and acoustic analysis of voice in professional singers without vocal complains. No immediate significant changes were observed with respect to auditory-perceptual evaluation of speech and singing.

    2017-03-01

    The purpose of this study is to analyze the vocal behavior of flamenco singers, as compared with classical music singers, to establish a differential vocal profile of voice habits and behaviors in flamenco music. Bibliographic review was conducted, and the Singer's Vocal Habits Questionnaire, an experimental tool designed by the authors to gather data regarding hygiene behavior, drinking and smoking habits, type of practice, voice care, and symptomatology perceived in both the singing and the speaking voice, was administered. We interviewed 94 singers, divided into two groups: the flamenco experimental group (FEG, n = 48) and the classical control group (CCG, n = 46). Frequency analysis, a Likert scale, and discriminant and exploratory factor analysis were used to obtain a differential profile for each group. The FEG scored higher than the CCG in speaking voice symptomatology. The FEG scored significantly higher than the CCG in use of "inadequate vocal technique" when singing. Regarding voice habits, the FEG scored higher in "lack of practice and warm-up" and "environmental habits." A total of 92.6% of the subjects classified themselves correctly in each group. The Singer's Vocal Habits Questionnaire has proven effective in differentiating flamenco and classical singers. Flamenco singers are exposed to numerous vocal risk factors that make them more prone to vocal fatigue, mucosa dehydration, phonotrauma, and muscle stiffness than classical singers. Further research is needed in voice training in flamenco music, as a means to strengthen the voice and enable it to meet the requirements of this musical genre. Copyright © 2017 The Voice Foundation.

    1995-12-01

    SIDA Dans La Cite (AIDS in the City) is a popular weekly soap opera first broadcast in Cote d'Ivoire in 1991 with 11 15-minute episodes. The series is part of a campaign by Population Services International (PSI) to raise awareness about AIDS among Ivorian youth. Actors worked for a nominal fee, editing studios were provided at substantial discounts, and filming equipment was borrowed for next to nothing. Production director realized how important the soap opera had become after the fourth episode. A study of 700 households in Abidjan found that of the 75% who had access to a television, two-thirds had seen at least one episode. Cote d'Ivoire may be one of the most religiously conservative countries in Africa. 10% of the adult population, however, is infected with HIV. All sectors of society therefore understand the need to openly understand and discuss sexual issues in the context of such high HIV prevalence. Studies indicate that virtually everyone in Cote d'Ivoire has heard of AIDS and knows that it is a sexually transmitted disease, but persuading people to change their behavior is difficult. PSI sells approximately 750,000 of its subsidized Prudence condoms. Prudence has the same brand recognition in the country as Nescafe and Toyota. A recent survey of sexually active teens found that 30% of girls and 45% of boys used condoms. A weekly radio show is broadcast live from one of the poorest ghettos of Abidjan. Guests include popular singers, comedians, and television personalities. The actors are often from SIDA Dans La Cite.

  20. Levi-Strauss and the Opera

    Directory of Open Access Journals (Sweden)

    Vlado Kotnik

    2016-02-01

    Full Text Available This paper is dedicated to Claude Levi-Strauss and his structural reading of opera as metaphorical ‘composing’ of an anthropological grand opera, materialized in the four-volume study of Mythologiques, which refers to Wagner’s tetralogy of The Ring. He created a type of comparative view of the function and structure of myth schemes in Amerindian culture and the orchestral scores of Wagner’s operas, and implicitly signalled that European music, with its eminent representation – opera – has had the same value or similar symbolic position in the mind and life of a contemporary European that myth has had in ‘the savage mind’. Through this, he can lead us to the understanding of opera as myth and metaphor. However, the paper extends the discussion on Levi-Strauss to a broader historical picture of the relationship between opera and mythology as two symbolic systems of European culture.

    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.

    objective questions about vocal habits and use of professional voice. Data were statistically analyzed RESULTS: popular singers have similar feeding habits as lyrical singers: smoking, alcohol and recreational drug use. Popular singers have fewer hours of sleep/rest along the day, which is a statistically significant difference. This group also differed from the lyrical singers because they have, in most cases, another work, with professional use of spoken voice. there was also a statistically significant increased workload on the use of singing voice in lyric singers, as well as the increased use of resources considering myths to improve the voice. Popular singers know less about the work of speech language pathologists with voice professionals. Lyrical singers warm up the voice with greater frequency over the popular singers, although this second group has demonstrated that this habit has been acquired. Both groups do not systematically slow down their voice, after the professional activity. CONCLUSION: popular and lyrical singers have some similar habits on the vocal health and they are different mainly due to the weekly to singing workload, using myths to improve voice, knowledge about the speech language pathologist work and voice warming-up practice.

    Choral singing is a popular vocational pastime across cultures. The potential health benefits associated with choral singing, including positive effect on well-being, are a topic of interest in health research. However, anecdotal reports from voice professionals suggest that the unique demands of choral singing may enforce unhealthy singing habits. This study explores suboptimal vocal behaviors that are sometimes associated with choral singing, which include singing outside comfortable pitch range, singing too loudly, and singing too softly for blend. The relationships between suboptimal choral singing habits, vocal warm-ups (WUs), vocal fatigue, and singing-related well-being were assessed via a 14-item Likert-based response format questionnaire. Participants consisted of 196 attendees of the international World Choir Games. The final study group consisted of 53 male and 143 female international amateur singers aged 10-70. Results indicated a positive correlation between vocal fatigue and suboptimal singing behaviors (r = 0.34, P singing behavior experienced increased singing-related well-being (r = -0.32, P singing well-being. Substantially, more participants from this demographic preferred choir over solo singing (X²[1, N = 196] = 22.93, P singing behaviors may result in vocal fatigue and reduction of choral singing well-being and should therefore be considered when examining the effect of choral singing on singing-related well-being and health. Future research will compare the amateurs' perceptions of choral singing with perceptions from professional singers and will look at determinants of choral singing well-being.

  8. [Production of accentuated personality traits in baroque opera : Opera buffa Arcifanfano-Re dei matti (1749)].

    Science.gov (United States)

    Brunner, J; Hirsch, T; Steger, F

    2016-05-01

    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.

  9. Peter Singer's argument for utilitarianism.

    Buckle, Stephen

    2005-01-01

    The paper begins by situating Singer within the British meta-ethical tradition. It sets out the main steps in his argument for utilitarianism as the 'default setting' of ethical thought. It argues that Singer's argument depends on a hierarchy of reasons, such that the ethical viewpoint is understood to be an adaptation--an extension--of a fundamental self-interest. It concludes that the argument fails because it is impossible to get from this starting-point in self-interest to his conception of the ethical point of view. The fundamental problem is its mixing the immiscible: the Humean subordination of reason to interest with the Kantian conception of reason as universal and authoritative.

    The performing arts mirror the human condition. This study sought to analyze the reasons for inclusion of visually impaired characters in opera, the cause of the blindness or near blindness, and the dramatic purpose of the blindness in the storyline. We reviewed operas from the 18 th century to 2010 and included all characters with ocular problems. We classified the cause of each character's ocular problem (organic, nonorganic, and other) in relation to the thematic setting of the opera: biblical and mythical, blind beggars or blind musicians, historical (real or fictional characters), and contemporary or futuristic. Cases of blindness in 55 characters (2 as a choir) from 38 operas were detected over 3 centuries of repertoire: 11 had trauma-related visual impairment, 5 had congenital blindness, 18 had visual impairment of unknown cause, 9 had psychogenic or malingering blindness, and 12 were symbolic or miracle-related. One opera featured an ophthalmologist curing a patient. The research illustrates that visual impairment was frequently used as an artistic device to enhance the intent and situate an opera in its time.

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

    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 attitude of Indian classical singers toward seeking vocal health care is a dimension yet to be explored. The current study was aimed to determine the attitudes of these singers toward seeking vocal health care and further understand the influence of age and gender. Cross-sectional. A 10-item self-report questionnaire adapted from a study on contemporary commercial music singers was used. An additional question was added to ask if the singer was aware about the profession and role of speech-language pathologists (SLPs). The questionnaire was administered on 55 randomly selected self-identified trained Indian classical singers who rated the items using a five-point Likert scale. Demographic variables were summarized using descriptive statistics and t test was used to compare the mean scores between genders and age groups. Of the singers, 78.2% were likely to see a doctor for heath-related problems, whereas 81.8% were unlikely to seek medical care for voice-related problems; the difference was statistically significant (P attitudes toward findings from medical examination by a specialist revealed a statistically significant difference (P = 0.02) between the genders. Age did not have a significant influence on the responses. Only 23.6% of the respondents were aware about the profession and the role of SLPs. The findings are in tune with western literature reporting hesitation of singers toward seeking vocal health care and draws attention of SLPs to promote their role in vocal health awareness and management.

    2006-01-01

    View of the OPERA detector (on the CNGS facility) with its two identical Super Modules, each of which contains one target section and one spectrometer.As the CNGS (CERN Neutrinos to Gran Sasso) project prepares to send its high intensity neutrino beam, some 730 km away in Italy, the OPERA collaboration is beginning to commission its electronic detectors in the underground Gran Sasso National Laboratory (LNGS). OPERA is ready to come on stage. Based in the INFN Gran Sasso National Laboratory, 732 km from CERN, the experiment will commission its electronic detectors with the high intensity neutrino beam sent by CNGS (see Bulletin n°29-30/2006). The OPERA Collaboration, which comprises 170 physicists from 35 research institutes and universities worldwide, aims to clear up the mystery of neutrino oscillation. The installation of the OPERA detector began in 2003 in Hall C of the underground laboratory at the LNGS. The detector is made of two identical Super Modules, each one containing one target section and ...

  16. Desiring T, desiring self: "T-style" pop singers and lesbian culture in China.

    2014-01-01

    This article examines an emerging group of "T-style" female singers in the popular music scene in China. The expression "T," which is developed from the term "tomboy," refers to lesbians with masculine gender style. It is a widely used form of identification in local lesbian communities in China. The emergence of "T-style" female singers coincided with the rapid development of local lesbian communities in major cities in China. By exploring the intersections-or mutual modeling-of "T-style" singers and local lesbian gender culture, this article also analyzes the different receptions of "T-style" singers by local lesbian women, and explores whether "T-style" singers are seen as a "cultural resource" that aids the construction of lesbian gender and sexual identities.

    This paper presents the findings from an evaluation of a creative musical project led by Scottish Opera. The project included people with dementia and their carers in the development, writing, design and performance of a musical production about their experiences of love. The project involved professional singers, artists and choreographers from the opera company. Activities involved practice sessions and performances. People with dementia and their carers reflected on positive outcomes from the project including improved confidence; being part of a group; improved physical strength and people seeing them in a new way. Within the evaluation framework they also reported on how the project had been run and gave ideas for future development. Key elements in the success of this project were the involvement of professionals, the kudos of working with a national organisation and the performances that, while daunting, provided unique and rewarding experiences. © The Author(s) 2013.

    2014-01-01

    Carnatic singing is a classical South Indian style of music that involves rigorous training to produce an "open throated" loud, predominantly low-pitched singing, embedded with vocal nuances in higher pitches. Voice problems in singers are not uncommon. The objective was to report the nature of voice problems and apply a routine protocol to assess the voice. Forty-five trained performing singers (females: 36 and males: 9) who reported to a tertiary care hospital with voice problems underwent voice assessment. The study analyzed their problems and the clinical findings. Voice change, difficulty in singing higher pitches, and voice fatigue were major complaints. Most of the singers suffered laryngopharyngeal reflux that coexisted with muscle tension dysphonia and chronic laryngitis. Speaking voices were rated predominantly as "moderate deviation" on GRBAS (Grade, Rough, Breathy, Asthenia, and Strain). Maximum phonation time ranged from 4 to 29 seconds (females: 10.2, standard deviation [SD]: 5.28 and males: 15.7, SD: 5.79). Singing frequency range was reduced (females: 21.3 Semitones and males: 23.99 Semitones). Dysphonia severity index (DSI) scores ranged from -3.5 to 4.91 (females: 0.075 and males: 0.64). Singing frequency range and DSI did not show significant difference between sex and across clinical diagnosis. Self-perception using voice disorder outcome profile revealed overall severity score of 5.1 (SD: 2.7). Findings are discussed from a clinical intervention perspective. Study highlighted the nature of voice problems (hyperfunctional) and required modifications in assessment protocol for Carnatic singers. Need for regular assessments and vocal hygiene education to maintain good vocal health are emphasized as outcomes. Copyright © 2014 The Voice Foundation. Published by Mosby, Inc.

    Full Text Available Previously we have described certain correlation between the protein composition of mixed saliva (PCMS and human psycho-emotional state (PES. In this investigation, the analysis of PCMS was used to study the change of PES in the group in the process of creative activities, i.e. choral singing. During the experiment, three groups of singers performed different parts of songs in the course of their regular sessions. The saliva for the analysis was collected from the singers just before and after the choral singing. The results led to the following conclusions. The vast number of singers showed evidence of healthy mental state. During the experiment, in each of the three creative teams there was a relatively harmonious PES of the participants. Collective singing strengthened the positive PES of the most singers. In particular, after singing in the choir a few people were found to have changed their PES from depressive to normal. Also, the processing of the collected data showed that the analysis of the PCMS characteristics allows evaluating not only the direction of the PES change against the background of the creative process, but also the depth of the emotional experience. In conclusion, the results of the research provide an objective basis for the confirmation of the beneficial effects of choral singing on the psyche of the singers.

    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.

    There is a belief among vocalists that there are voice benefits from vitamin B 12 treatment. Yet there are no previous reports regarding vitamin B 12 effects on voice. To assess the prevalence of vitamin B 12 use among singers and their beliefs regarding vitamin B 12 therapy. Anonymous online survey administered to singers, singing-teachers, speech-language pathologists, and laryngologists. A total of 192 participants completed the surveys; 128 singers (68 singing-teachers, 30 speech-language pathologists) and 64 laryngologists. Among singers, 12% have perceived voice benefits from vitamin B 12 treatment taken for any reason. Four percent used vitamin B 12 for voice benefits; all perceived voice benefits as a result. The leading voice benefits were improved stamina, reduced effort, confidence, and control. Nineteen percent of the singers would recommend vitamin B 12 treatment to a friend; 15% of the singing-teachers would recommend it to a student. Among laryngologists, 33% been asked by a singer to prescribe vitamin B 12 for voice benefits; 9% have prescribed it in the past. Yet only 3% would you recommend it to a patient. When asked "Do you believe vitamin B 12 therapy improves vocal performance?" 31% of the singers responded "Yes," compared with none in the laryngologists. When asked "Do you think the singing community believes vitamin B 12 therapy improves vocal performance?" 26% of the singers responded "Yes," compared with 53% of the laryngologists (P = 0.0002). There is a discrepancy between the singers' and the laryngologists' beliefs regarding vocal benefits perceived by vitamin B 12 . Blinded randomized trials are required to verify or refute this belief. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

    The study aimed to review the prevalence of self-reported voice disorders in singers. The study is a systematic review and meta-analysis. A systematic review of five major scientific databases was conducted. An extensive search strategy was used considering the rules of each database. Original articles were included only if they had data related to self-perception of dysphonia in the past. Furthermore, heterogeneity and its relative significance were assessed. There were 2371 articles identified; duplicates were deleted, screenings were conducted, and inclusion and exclusion criteria were applied. The final analysis was conducted on 11 studies. The most implemented instruments for the study were customized questionnaires. The findings about singing styles, voice use, and age were found to be different among subjects. The overall prevalence of self-reported dysphonia in singers was 46.09% (95% confidence interval: 38.16-54.12). The heterogeneity was considerable among the studied samples (I 2  = 90.59%). Four groups were then established-students, teachers, classical, and nonclassical-and compared regarding overall prevalence (21.76% in students, and significantly higher and nondifferent in the other three groups, 55.15%, 40.53%, and 46.96%, respectively) and heterogeneity (low only for the students' studies). Although with low homogeneity, singers present a high prevalence of self-perceived dysphonia over their careers. Singing students were the group with a lower prevalence. On the other hand, traditional and popular music singers, as well as singing teachers, revealed significantly higher prevalence of self-perceived dysphonia. Overall, singers are likely to report voice disorders, no matter their singing style or skills. This highlights the need of a preventive approach to address voice disorders in traditional and untrained singers. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc.

    2013-09-01

    Some acoustic characteristics of the two types of vocal music of the Greek Orthodox Church Music, the Byzantine chant (BC) and ecclesiastical speech (ES), are studied in relation to the common Greek speech and the Western opera. Vocal samples were obtained, and their acoustic parameters of sound pressure level (SPL), fundamental frequency (F0), and the long-time average spectrum (LTAS) characteristics were analyzed. Twenty chanters, including two chanters-singers of opera, sang (BC) and read (ES) the same hymn of Byzantine music (BM), the two opera singers sang the same aria of opera, and common speech samples were obtained, and all audio were analyzed. The distribution of SPL values showed that the BC and ES have higher SPL by 9 and 12 dB, respectively, than common speech. The average F0 in ES tends to be lower than the common speech, and the smallest standard deviation (SD) of F0 values characterizes its monotonicity. The tone-scale intervals of BC are close enough to the currently accepted theory with SD equal to 0.24 semitones. The rate and extent of vibrato, which is rare in BC, equals 4.1 Hz and 0.6 semitones, respectively. The average LTAS slope is greatest in BC (+4.5 dB) but smaller than in opera (+5.7 dB). In both BC and ES, instead of a singer's formant appearing in an opera voice, a speaker's formant (SPF) was observed around 3300 Hz, with relative levels of +6.3 and +4.6 dB, respectively. The two vocal types of BM, BC, and ES differ both to each other and common Greek speech and opera style regarding SPL, the mean and SD of F0, the LTAS slope, and the relative level of SPF.

    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.

  11. Castrati singers--all for fame.

    The phenomenon of castration is very closely associated with the baroque era. In a period that placed emphasis on pure sensual pleasure, castrati singers, with their angelic voices, were a perverted outcome of this ambition. It was the intention that these castrato voices with their supernatural sound would mesmerize audiences. At that time, it could be said that within certain society circles, an addiction to these voices existed. Equally, they were oblivious to the spiritual side of the lives of the castrati. Farinelli, Caffarelli, and Senesino, three of the most famous castrati, were the first musical superstars of the 18th century. Their voices moved decadent audiences to tears and standing ovations. The price for this fame was, however, high. The aim of this review is to provide an overview of castrati singers, especially in the baroque era, their sexuality and the effects of castration on their physical development. A literature search of relevant databases, books, and articles in journals was performed and compared with current data concerning androgen suppression and endocrine aspects of male sexual dysfunction. The effects of castration on physical development were notoriously erratic. Much depended on the timing of the operation: boys pruned before the age of 10 or so very often grew up with feminine features; smooth, hairless bodies, incipient breasts, infantile penis, and often a complete lack of sex drive. The peak success of the castrati ended with the end of the 18th century. The last castrato was Alessandro Moreschi, a solo singer in the choir of the Sistine Chapel of the Vatican. Following the ban on castration, Pope Pius X sent him into retirement in 1912, thus putting an end to a very impressive part of the history of music. © 2012 International Society for Sexual Medicine.

    In the context of developing and testing a procedure for "Outcome-oriented payment for rehabilitation after stroke", we found that the instruments commonly used to measure the outcomes of rehabilitation after stroke (e. g., Barthel-Index or FIM) were not meeting the special requirements of the new payment system. Therefore the "Scores of Independence for Neurologic and Geriatric Rehabilitation" (SINGER) was developed as a new assessment instrument. This instrument is based on the ICF and measures 20 aspects of "independence in activities of daily living". The characteristic feature of the SINGER is, above all, the way all items are graded in 6 steps: the gradation does not refer to the degree of disability but to the kind and amount of help required for the respective activity, i. e.: 0 = totally dependent on professional help; 1 = professional contact help needed; 2 = contact help by (instructed) lay persons sufficient; 3 = preparation or supervision by lay persons still needed; 4 = independent with assistive device or still slow; 5 = independent without assistive device. For experienced personnel in neurologic rehabilitation, these gradations are "intuitively plausible". A manual moreover describes each grade in detail for each item so that the instrument can be used in rehabilitation facilities without extensive training. The SINGER has been tested and validated in a pilot study (n = 100) and in 2 subsequent studies with large case numbers in neurologic rehabilitation (n = 1058 and n = 700 patients after stroke in all categories of severity). Factor analyses showed that the instrument contains 2 dimensions which can be interpreted as "physical activities" and "activities of communication and cognition". Each of these 2 dimensions can be split into 2 sub-dimensions that can be assigned to the tasks of therapeutical professions in care/Occupational Therapy, physiotherapy, logopedics, and neuro- psychology.

    We study how much the unique ability of the OPERA experiment to directly detect {nu}{sub {tau}} can help in probing new, non-standard contact interactions of the third family of neutrinos. We perform a combined analysis of future, high-statistics MINOS and OPERA data. For the case of non-standard interactions in {nu}{sub {mu}} to {nu}{sub e} transitions we also include the impact of possible Double Chooz data. In all cases we find that the {nu}{sub {tau}} sample of OPERA is too small to be statistically significant, even if one doubles the nominal exposure of OPERA to 9x10{sup 19} pot. OPERA's real benefit for this measurement lies in its very high neutrino energy and hence very different L/E compared to MINOS.

  15. Evidence for enhanced interoceptive accuracy in professional musicians

    2015-12-01

    Full Text Available Interoception is defined as the perceptual activity involved in the processing of internal bodily signals. While the ability of internal perception is considered a relatively stable trait, recent data suggest that learning to integrate multisensory information can modulate it. Making music is a uniquely rich multisensory experience that has shown to alter motor, sensory, and multimodal representations in the brain of musicians. We hypothesize that musical training also heightens interoceptive accuracy comparable to other perceptual modalities. Thirteen professional singers, twelve string players, and thirteen matched non-musicians were examined using a well-established heartbeat discrimination paradigm complemented by self-reported dispositional traits. Results revealed that both groups of musicians displayed higher interoceptive accuracy than non-musicians, whereas no differences were found between singers and string-players. Regression analyses showed that accumulated musical practice explained about 49% variation in heartbeat perception accuracy in singers but not in string-players. Psychometric data yielded a number of psychologically plausible inter-correlations in musicians related to performance anxiety. However, dispositional traits were not a confounding factor on heartbeat discrimination accuracy. Together, these data provide first evidence indicating that professional musicians show enhanced interoceptive accuracy compared to non-musicians. We argue that musical training largely accounted for this effect.

    The OPERA collaboration has recently reported that neutrinos travel faster than light. We review the theoretical situation of constraints on violations of Lorentz invariance, focusing in particular on the compatibility between the OPERA results with both previous constraints and recently obtained ones. We generalize to higher order operators the recent constraint provided by the absence of neutrino energy loss, via electron-positron pair production at OPERA energies, and show that no modi ed in vacuo dispersion relation within an effective field theory context is compatible with OPERA results. We conclude that the OPERA result is incompatible with current observations, at least without resorting to models beyond effective field theory, possibly with local environmental effects. (orig.)

    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.

    The current study aimed at investigating the immediate effects of a semi-occluded vocal tract exercise with a ventilation mask in a group of contemporary commercial singers. A randomized controlled study was carried out. Thirty professional or semi-professional singers with no voice complaints were randomly divided into two groups on recruitment: an experimental group and a control group. The same warm-up exercise was performed by the experimental group with an occluded ventilation mask placed over the nose and the mouth and by the control group without the ventilation mask. Voice was recorded before and after the exercise. Acoustic and self-assessment analysis were accomplished. The acoustic parameters of the voice samples recorded before and after training were compared, as well as the parameters' variations between the experimental and the control group. Self-assessment results of the experimental and the control group were compared too. Significant changes after the warm-up exercise included jitter, shimmer, and singing power ratio (SPR) in the experimental group. No significant changes were recorded in the control group. Significant differences between the experimental and the control group were found for ΔShimmer and ΔSPR. Self-assessment analysis confirmed a significantly higher phonatory comfort and voice quality perception for the experimental group. The results of the present study support the immediate advantageous effects on singing voice of a semi-occluded vocal tract exercise with a ventilation mask in terms of acoustic quality, phonatory comfort, and voice quality perception in contemporary commercial singers. Long-term effects still remain to be studied. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

    Maintaining good health is essential for touring musicians and singers. The stressful demands of touring may impact food choices, leading to detrimental effects on health and performance. This exploratory pilot study aimed to assess factors affecting healthful eating of touring musicians and singers. A 46-item survey was used to assess food- and nutrition-related attitudes, knowledge and behaviors, and environmental factors, as well as lifestyle, musical background, and demographic data. Participants (n=35) were recruited from a musicians' assistance foundation as well as touring musical theater productions and a music festival. Results indicate that touring musicians and singers had positive attitudes regarding healthful foods. Of 35 respondents, 80.0% indicated eating healthful food was important to them. Respondents reported feeling confident selecting (76.5%) and preparing (82.4%) healthful foods; however, they showed uncertainty when determining if carbohydrate-containing foods should be consumed or avoided. Respondents indicated environmental factors including availability and cost of healthy food options and tour schedules limited access to healthful foods. Venues (73.5%), fast food restaurants (67.6%), and airports (64.7%) were the most frequently identified locations in need of offering more healthful food choices. Respondents (52.9%) indicated more support from others while touring would help them make healthier food choices. More research is needed to develop mobile wellness programs as well as performance-based nutrition guidelines for musicians and singers that address the unique demands associated with touring.

    The purpose of this study was to evaluate vocal tract function and the voice quality in singers with muscle tension dysphonia (MTD) after undergoing combined functional voice therapy of the singing voice. This is a prospective, randomized study. Forty singers (29 females and 11 males, mean age: 24.6 ± 8.8 years) with MTD were enrolled in the study. The study group consisted of 20 singers who underwent combined functional voice therapy (10-15 individual sessions, 30-40 minutes each). Singers who did not opt for vocal rehabilitation consisted of the control group. Effects of rehabilitation were assessed with videolaryngostroboscopy, palpation of the vocal tract structures, flexible fiberoptic evaluation of the pharynx and the larynx, perceptual speaking and singing voice assessment, acoustic analysis, maximal phonation time, and the Voice Handicap Index. After combined functional voice therapy in the study group, great improvement was noticed in palpation of the vocal tract structures (P singing range obtained from acoustic analysis of glissando (P singing. Development of palpation and perceptual singing voice examination protocols enables one to compare results before and after rehabilitation in clinics. Copyright © 2017 The Voice Foundation.

    Pierpaolo Polzonetti

    2016-12-01

    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.

    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

    OPERAS is a personal-computer (PC) based software to collect and process simulator data on control-room operators responses during requalification training scenarios. The data collection scheme is based upon approach developed earlier during the EPRI Operator Reliability Experiments project. The software allows automated data collection from simulator, thus minimizing simulator staff time and resources to collect, maintain and process data which can be useful in monitoring, assessing and enhancing the progress of crew reliability and effectiveness. The system is designed to provide the data and output information in the form of user-friendly charts, tables and figures for use by plant staff. OPERAS prototype software has been implemented at the Diablo Canyon (PWR) and Millstone (BWR) plants and is currently being used to collect operator response data. Data collected from similator include plant-state variables such as reactor pressure and temperature, malfunction, times at which annunciators are activated, operator actions and observations of crew behavior by training staff. The data and systematic analytical results provided by the OPERAS system can contribute to increase objectivity by the utility probabilistic risk analysis (PRA) and training staff in monitoring and assessing reliability of their crews

    Wonsak, Bjoern [Universitaet Hamburg (Germany)

    2012-07-01

    OPERA is a long-baseline neutrino oscillation experiment designed to find tau neutrinos appearing in a pure muon neutrino beam. Recently, a measurement of the flight time of the neutrinos between the CNGS at CERN and the OPERA detector at the LNGS has been performed. It was found that the neutrinos arrive at the detector significantly earlier in time than expected if travelling at the speed of light. In this talk, the main aspects of this measurement are presented, including timing and geodesy issues and the analysis procedure. An update concerning results with a fine structured time distribution of the beam is given, as well as latest information on some additional cross checks.

    This report will describe introduction of validation of OPERA3D code, and validation results that are directly related with PCMI phenomena. OPERA3D was developed for the PCMI analysis and validated using the in-pile measurement data. Fuel centerline temperature and clad strain calculation results shows close expectations with measurement data. Moreover, 3D FEM fuel model of OPERA3D shows slight hour glassing behavior of fuel pellet in contact case. Further optimization will be conducted for future application of OPERA3D code. Nuclear power plant consists of many complicated systems, and one of the important objects of all the systems is maintaining nuclear fuel integrity. However, it is inevitable to experience PCMI (Pellet Cladding Mechanical Interaction) phenomena at current operating reactors and next generation reactors for advanced safety and economics as well. To evaluate PCMI behavior, many studies are on-going to develop 3-dimensional fuel performance evaluation codes. Moreover, these codes are essential to set the safety limits for the best estimated PCMI phenomena aimed for high burnup fuel.

    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)

  14. Pro-development soap operas: a novel approach to development communication.

    Brown, W J; Singhal, A; Rogers, E M

    1989-01-01

    Soap operas have their roots in 18th century English romance novels. These evolved into serialized radio dramas. In their current form, they were developed primarily to attract large audiences in order to sell consumer products. Hence the name soap which refers to the soap manufacturers who commonly advertise on such programs. In the world of soap operas there are 2 kinds. Those that function primarily to entertain and sell consumer products, and those that primarily entertain, but infuse positive social messages. The former are found everywhere, but are the only kind in America. The latter are found exclusively in developing countries. American soap operas have conveyed pro-social messages in the past, but they differ fundamentally from pro-development soap operas in their theoretical foundations. American soap operas are created by people who want to sell consumer goods. Development soap operas are created by people who want to convey pro-social messages that will aid their country's development. Both must be popular in order to be successful, but the former lack moral coherency, are unrealistic, erode values, and are created through a process of a theoretical development; while the latter have moral coherency, are realistic, promote values, and are created through a process of theoretical development. The 1st pro-development soap opera was Ven Conmigo (Come With Me) and was produced in Mexico between 1975-76. Its primary purpose was to increase adult literacy. During the year it ran, applicants at adult literacy centers rose by 600,000 or 63% compared to 7% the year before, and 2% the year after. The 2nd pro-development soap opera was Acompaname (Accompany Me) and it primary purpose was to promote family planning. It ran from 1977-78 and during that time the number of family planning adopters rose by 560,000 and contraceptive sale sin Mexico rose sharply. The question of what are pro-social messages and who should control them must be answered by each country in

    Full Text Available OBJETIVO: Investigar os efeitos da aplicação de um Programa de Desenvolvimento da Coordenação Motora, baseado em Piret e Béziers, na voz do cantor lírico. MÉTODOS: Cinco cantores líricos profissionais executaram uma ária de ópera, de livre escolha, que foi filmada. Em seguida responderam a uma questão sobre a propriocepção ao cantar. Durante um mês submeteram-se ao Programa de Desenvolvimento da Coordenação Motora e ao final gravaram novamente a mesma ária e responderam a mesma questão. As filmagens foram enviadas para nove juizes profissionais (três fonoaudiólogos, três fisioterapeutas e três professores de canto que avaliaram a integração corpo e voz dos cantores por meio de análise perceptivo-auditiva e visual. Os cantores, após assistirem às duas filmagens, fizeram outra auto-avaliação. RESULTADOS: Na avaliação dos juízes: as duas sopranos, a mezzo-soprano e o baixo melhoraram a projeção da voz; o tenor melhorou a ressonância e o baixo melhorou também a respiração; com exceção do baixo todos ficaram com os gestos mais livres. Segundo relato dos cantores, os exercícios garantiram maior percepção da tensão muscular durante o canto e isso possibilitou melhor controle dos gestos. CONCLUSÃO: De acordo com a avaliação subjetiva os ajustes posturais, oriundos da execução dos exercícios da coordenação motora, provavelmente garantiram abertura da caixa torácica e melhoraram as condições da respiração dos cantores, durante o canto; este fato pode ter favorecido a verticalização da ressonância e a projeção da voz.PURPOSE: To investigate the effects of the application of a Motor Coordination Development Program, based on Piret and Béziers, on the voice of lyric singers.

  17. The Illness and Death of Enrico Caruso (1873-1921): A Medical Chorus Out of Tune?

    Science.gov (United States)

    Cascella, Marco

    2016-02-01

    The Italian opera singer Enrico Caruso is considered by many people the most famous opera singer of all time or "The Matchless Singer" for his unique and suggestive vocal timber. Although a man of humble origins, he managed to rise from poverty, thanks to his extraordinary intelligence and determination. From his debut in 1895 in Naples, until December 24, 1920, the tenor had a brilliant career with many performances and over 500 songs in his repertoire. This intense lifestyle went on until 1919, when the fortune that had always accompanied him began to fade and he entered a fast "descending parable." In this study, we analyze Caruso's medical history during his last year of life: Through the study of the newspapers from the period and the statements reported on the tenor's many biographies, we tried to offer a detailed evaluation of the complex pathogenic chain of events that led to his death, impeding him from keeping to alleviate the heart-breaking nostalgia of many emigrants that felt in his singing the warmth of a too distant land.

  18. VHI-10 and SVHI-10 Differences in Singers' Self-perception of Dysphonia Severity.

    2017-05-01

    Previous investigations of the Voice Handicap Index (VHI)-10 in clinical practice noted that specific information relevant to singers was not forthcoming. Consequently, a second index, the Singing Voice Handicap Index (SVHI) as well as its shortened counterpart the SVHI-10, was developed. The purpose of this study was to directly compare the differences in scores between the VHI-10 and the SVHI-10 in a group of 50 singers. A retrospective chart review of 50 singers (26 women, 24 men) was performed between June 2014 and November 2014 at Weill Cornell Medical College, New York. Subjects completed both the VHI-10 and the SVHI-10 at their initial evaluation. The results from the VHI-10 and the SVHI-10 were then compared using paired t test and two-way analysis of variance. The SVHI-10 scores from the performers were significantly higher than those of the VHI-10 (P < 0.0001). The mean score on the VHI-10 was 12.1 compared with 20.4 on the SVHI-10 (maximum score for each questionnaire is 40). There were no significant gender differences when comparing the VHI-10 and the SVHI-10 on the overall scores or for individual items. The analysis of variance also found no significant gender difference (P = 0.865) and confirmed a significant difference between VHI-10 and SVHI-10 (P = 0.0003). Whereas singers may have general complaints about their voice, they also have specific complaints that relate only to their singing voice. Finding a significant difference between the scores of the VHI-10 and the SVHI-10 suggests the importance of assessing the singer's perception of voice severity using a tool that focuses on the singing voice.

    2007-01-01

    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

  1. A Mozart is not a Pavarotti: singers outperform instrumentalists on foreign accent imitation.

    Christiner, Markus; Reiterer, Susanne Maria

    2015-01-01

    Recent findings have shown that people with higher musical aptitude were also better in oral language imitation tasks. However, whether singing capacity and instrument playing contribute differently to the imitation of speech has been ignored so far. Research has just recently started to understand that instrumentalists develop quite distinct skills when compared to vocalists. In the same vein the role of the vocal motor system in language acquisition processes has poorly been investigated as most investigations (neurobiological and behavioral) favor to examine speech perception. We set out to test whether the vocal motor system can influence an ability to learn, produce and perceive new languages by contrasting instrumentalists and vocalists. Therefore, we investigated 96 participants, 27 instrumentalists, 33 vocalists and 36 non-musicians/non-singers. They were tested for their abilities to imitate foreign speech: unknown language (Hindi), second language (English) and their musical aptitude. Results revealed that both instrumentalists and vocalists have a higher ability to imitate unintelligible speech and foreign accents than non-musicians/non-singers. Within the musician group, vocalists outperformed instrumentalists significantly. First, adaptive plasticity for speech imitation is not reliant on audition alone but also on vocal-motor induced processes. Second, vocal flexibility of singers goes together with higher speech imitation aptitude. Third, vocal motor training, as of singers, may speed up foreign language acquisition processes.

    2003-08-01

    A model of the auditory process is proposed for performing singers, which incorporates the added signal from bone conduction, as well as the psychological distance for subjective preference of the performer from the acoustic sound field of the stage. The explanatory power of previous scientific studies of vocal stage acoustics has been limited by a lack of an underlying theory of performer preference. Ando's theory, using the autocorrelation function (ACF) for parametrizing temporal factors, was applied to interpretation of singer sound field preference determined by the pair comparison method. Melisma style singing (no lyrics) was shown to increase the preferred delay time of reflections from a mean of 14 ms with lyrics to 23 ms without (pThesis advisor: Yoichi Ando Copies of this thesis are available from the author by inquiry at BRC Acoustics, 1741 First Avenue South, Seattle, WA 98134 USA.

    2014-01-01

    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)

    Differences in classical and non-classical singing are due primarily to aesthetic style requirements. The head position can affect the sound quality. This study aimed at comparing the head position for famous classical and non-classical male singers performing high notes. Images of 39 Western classical and 34 non-classical male singers during live performances were obtained from YouTube. Ten raters evaluated the frontal rotational head position (depression versus elevation) and transverse head position (retraction versus protraction) visually using a visual analogue scale. The results showed a significant difference for frontal rotational head position. Most non-classical singers in the sample elevated their heads for high notes while the classical singers were observed to keep it around the neutral position. This difference may be attributed to different singing techniques and phonatory system adjustments utilized by each group.

    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.){sub −8.0}{sup +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.){sub −3.3}{sup +3.4}(sys.))×10{sup −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.

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

    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.

    2016-01-01

    OPERA (Oscillation Project with Emulsion tRacking Apparatus) was a long-baseline experiment at the Gran Sasso laboratory (LNGS) designed to search for ν μ → ν τ oscillations in appearance mode. OPERA took data from 2008 to 2012 with the CNGS neutrino beam from CERN. The observation of five ν τ candidates allowed assessing the discovery of ν μ → ν τ appearance in the CNGS neutrino beam with a significance of 5 . 1 σ . The data analysis is still ongoing, with the goal of improving the sensitivity to the sterile neutrino search in the ν μ → ν τ and ν μ → ν e appearance channels and oscillation parameters with reduced statistical uncertainties. Current results will be presented and perspectives discussed.

  16. Interpreting OPERA results on superluminal neutrino

    Giudice, Gian F; Strumia, Alessandro

    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.

    Full Text Available The paper considers the methodologic problems of an all-round analysis of the image of an opera character as the object of compositional interpretation. For the first time in musicology there are examined the means of expression of a given character created by the librettist and composer — the authors of the opera. The author presents the main directions of this analysis that give the possibility to present the artistic image of the opera character in the most complex form. The main principles of the paper are illustrated by examples taken from world opera literature.

    described acoustically by the rate, extent and periodicity of frequency modulations and amplitude modulations of the voice. PROCEDURES: an opera singer student, 25-year-old, lyric baritone, with normal voice from the perceptual point of view. The correction of vibrato is carried through by using the method "Rhythmic vibrato training". One produces a rhythmic pulse subdivision or unit of time during a vowel emission with "time" or speed constant. Subsequently, there is a variation in pulse speed, vowels and melody. The acoustic parameters of vibrato are evaluated objectively before and after training. RESULTS: the patient succeeded to produce a vibrato with rate, extent, and regularity within the normal ranges. Vibrato production was carried through in a conscious directed way by using abdominal and laryngeal activity at the same time. The vibrato continued improving after the training had been completed. CONCLUSIONS: it is possible to train and correct the vibrato in a targeted way through specific exercises, intended for such purpose. The visual biofeedback plays an important role on the outcome.

  19. "Ring" in the solo child singing voice.

    2014-03-01

    Listeners often describe the voices of solo child singers as being "pure" or "clear"; these terms would suggest that the voice is not only pleasant but also clearly audible. The audibility or clarity could be attributed to the presence of high-frequency partials in the sound: a "brightness" or "ring." This article aims to investigate spectrally the acoustic nature of this ring phenomenon in children's solo voices, and in particular, relating it to their "nonring" production. Additionally, this is set in the context of establishing to what extent, if any, the spectral characteristics of ring are shared with those of the singer's formant cluster associated with professional adult opera singers in the 2.5-3.5kHz region. A group of child solo singers, acknowledged as outstanding by a singing teacher who specializes in teaching professional child singers, were recorded in a major UK concert hall performing Come unto him, all ye that labour, from the aria He shall feed his flock from The Messiah by GF Handel. Their singing was accompanied by a recording of a piano played through in-ear headphones. Sound pressure recordings were made from well within the critical distance in the hall. The singers were observed to produce notes with and without ring, and these recordings were analyzed in the frequency domain to investigate their spectra. The results indicate that there is evidence to suggest that ring in child solo singers is carried in two areas of the output spectrum: first in the singer's formant cluster region, centered around 4kHz, which is more than 1000Hz higher than what is observed in adults; and second in the region around 7.5-11kHz where a significant strengthening of harmonic presence is observed. A perceptual test has been carried out demonstrating that 94% of 62 listeners label a synthesized version of the calculated overall average ring spectrum for all subjects as having ring when compared with a synthesized version of the calculated overall average nonring

    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.

    A new type of coded aperture configuration that enables fast decoding of the coded aperture shadowgram data is presented. Based on the products of incidence vectors generated from the Singer difference sets, we call these Singer product apertures. For a range of aperture dimensions, we compare experimentally the performance of three decoding methods: standard decoding, induction decoding and direct vector decoding. In all cases the induction and direct vector methods are several orders of magnitude faster than the standard method, with direct vector decoding being significantly faster than induction decoding. For apertures of the same dimensions the increase in speed offered by direct vector decoding over induction decoding is better for lower throughput apertures.

    Neto, Leon; Meyer, David

    2017-03-01

    Contemporary commercial music (CCM) is a term that encompasses many styles of music. A growing subset of CCM is contemporary Christian music, a genre that has outpaced other popular styles such as Latin, jazz, and classical music. Contemporary Christian singers (CCSs) and worship leaders (WLs) are a subset of CCM musicians that face unique vocal demands and risks. They typically lack professional training and often perform in acoustically disadvantageous venues with substandard sound reinforcement systems. The vocal needs and risks of these singers are not well understood, and because of this, their training and care may be suboptimal. The aim of the present study was to investigate the vocal health of this growing population and their awareness of standard vocal hygiene principles. An online questionnaire was designed and administered to participants in the Americas, Europe, Australia, and Asia. A total of 614 participants responded to the questionnaire, which is made available in English, Portuguese, and Spanish. Many participants reported vocal symptoms such as vocal fatigue (n = 213; 34.7%), tickling or choking sensation (n = 149; 24.3%), loss of upper range (n = 172; 28%), and complete loss of voice (n = 25; 4.1%). One third of the participants (n = 210; 34%) indicated that they do not warm up their voices before performances and over half of the participants (n = 319; 52%) have no formal vocal training. Results suggest that this population demonstrates low awareness of vocal hygiene principles, frequently experience difficulty with their voices, and may face elevated risk of vocal pathology. Future studies of this population may confirm the vocal risks that our preliminary findings suggest. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

    2016-05-01

    Speech-language pathologists have long used technology for the clinical measurement of the speaking voice, but present research shows that vocal pedagogues and voice students are becoming more accepting of technology in the studio. As a result, the equipment and technology used in singing voice studios by speech-language pathologists and vocal pedagogues are changing. Although guides exist regarding equipment and technology necessary for developing a voice laboratory and private voice studio, there are no data documenting the current implementation of these items and their perceived effectiveness. This study seeks to document current trends in equipment used in voice laboratories and studios. Two separate surveys were distributed to 60 vocologists and approximately 300 student singers representative of the general singing student population. The surveys contained questions about the inventory of items found in voice studios and perceived effectiveness of these items. Data were analyzed using descriptive analyses and statistical analyses when applicable. Twenty-six of 60 potential vocologists responded, and 66 student singers responded. The vocologists reported highly uniform inventories and ratings of studio items. There were wide-ranging differences between the inventories reported by the vocologist and student singer groups. Statistically significant differences between ratings of effectiveness of studio items were found for 11 of the 17 items. In all significant cases, vocologists rated usefulness to be higher than student singers. Although the order of rankings of vocologists and student singers was similar, a much higher percentage of vocologists report the items as being efficient and effective than students. The historically typical studio items, including the keyboard and mirror, were ranked as most effective by both vocologists and student singers. Copyright © 2016 The Voice Foundation.

    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

    2012-01-01

    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.

    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...

    2017-07-01

    China's traditional Peking Opera has four standard categories of roles: Sheng, Dan, Jing, and Chou, the singing vibrato of each displaying a different auditory effect. The audio and respiratory signals were recorded for two performers of the Qing Yi role, one of the Jing role, one of the Chou role, one of the Lao Sheng role, one of the Xiao Sheng role, and one of the Lao Dan role. The recordings gained eventually consisted of 24 representative songs from six roles. The rates and extents of vibrato, fundamental frequency, and rib cage signals were analyzed. Two findings were obtained: (1) the classical opera singing vibratos of China and Western countries are acoustically different from each other; and (2) in Peking Opera, the singing vibratos of different roles show significant acoustic differences.

They are amongst those essential knowledges that every music teacher and student (at secondary school and university level must possess. This paper stands as a discovery journey into one of the fundamental dramatic-musical devices of ninetheenth-century opera duet, the so called ‘solita forma’. It is explored chronologically and in its various forms by examining some exemplary pieces, from Rossini’s Tancredi (1813 to Verdi’s Aida (1871. This analysis can also be of value as a listening didactic unit.

    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

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

  3. Atiyah-Patodi-Singer index theorem for domain-wall fermion Dirac operator

    Science.gov (United States)

    Fukaya, Hidenori; Onogi, Tetsuya; Yamaguchi, Satoshi

    2018-03-01

    Recently, the Atiyah-Patodi-Singer(APS) index theorem attracts attention for understanding physics on the surface of materials in topological phases. Although it is widely applied to physics, the mathematical set-up in the original APS index theorem is too abstract and general (allowing non-trivial metric and so on) and also the connection between the APS boundary condition and the physical boundary condition on the surface of topological material is unclear. For this reason, in contrast to the Atiyah-Singer index theorem, derivation of the APS index theorem in physics language is still missing. In this talk, we attempt to reformulate the APS index in a "physicist-friendly" way, similar to the Fujikawa method on closed manifolds, for our familiar domain-wall fermion Dirac operator in a flat Euclidean space. We find that the APS index is naturally embedded in the determinant of domain-wall fermions, representing the so-called anomaly descent equations.

    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.)

    Scaffolding, the problem of ordering and orienting contigs, typically using paired-end reads, is a crucial step in the assembly of high-quality draft genomes. Even as sequencing technologies and mate-pair protocols have improved significantly, scaffolding programs still rely on heuristics, with no guarantees on the quality of the solution. In this work, we explored the feasibility of an exact solution for scaffolding and present a first tractable solution for this problem (Opera). We also describe a graph contraction procedure that allows the solution to scale to large scaffolding problems and demonstrate this by scaffolding several large real and synthetic datasets. In comparisons with existing scaffolders, Opera simultaneously produced longer and more accurate scaffolds demonstrating the utility of an exact approach. Opera also incorporates an exact quadratic programming formulation to precisely compute gap sizes (Availability: http://sourceforge.net/projects/operasf/ ).

  7. Particle identification by nuclear emulsions in the OPERA experiment

    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)

    Full Text Available There is a relationship between musical performance and body movement (Palmer, 1997. Visual perception of musicians can influence the reception of the work by the audience, even more decisive than through hearing (Juchniewicz, 2008. In the case of women singers in live events, the spectacle of one's body through nonverbal language and music is not particularly plausible, and often refers to sexuality (Davidson, 2005, Koskoff, 1989. In this exploratory study we have considered the implications and the visual impact of the proposal of a pop singer contrary to the norm. Through content analysis and interviews with the public in a concert of The Punsetes Madrid group, it follows the subversive nature of their singer and performer. This subversion works on an immediate level, through the frustration of the expectations of the audience.

    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

    2010-05-01

    Although quantifiable assessment of the singing voice is now commonplace, research on young (child and adolescent) voices is still in its infancy. There is still insufficient data on young people's voices based on which, "norms" in behavior could be modeled, particularly for contemporary commercial music (CCM), such as musical theater (MT). The objective of this study was to assess if quantifiable differences in vocal production and acoustic output of young singers exist between "classical" and "MT" styles. The study was a prospective cohort study of 20 adolescent female singers aged 12-17 years training their voices using a system, which includes both "classical" and "MT" styles. The study examined laryngographically derived closed quotient (CQ), average vowel spectra (AVS) and long-term average spectra (LTAS) measures of the sung voices of singers in "classical" and "MT" styles. The spectral slope was shallower for the MT voice, and the mean CQ was significantly higher across the pitch range when singing in an MT style than in a "classical" style. The second to fifth harmonics were stronger in the MT style than in classical, with a significant difference between the two styles. The increase in relative intensity in the first five harmonics was disproportionately higher than the increase in CQ. Results, therefore, suggested that MT singing primarily uses change in resonance strategy rather than raised vocal tension to achieve the tonal changes associated with the genre.

    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.)

  20. The acoustic and perceptual differences to the non-singer's singing voice before and after a singing vocal warm-up

    Science.gov (United States)

    DeRosa, Angela

    The present study analyzed the acoustic and perceptual differences in non-singer's singing voice before and after a vocal warm-up. Experiments were conducted with 12 females who had no singing experience and considered themselves to be non-singers. Participants were recorded performing 3 tasks: a musical scale stretching to their most comfortable high and low pitches, sustained productions of the vowels /a/ and /i/, and singing performance of the "Star Spangled Banner." Participants were recorded performing these three tasks before a vocal warm-up, after a vocal warm-up, and then again 2-3 weeks later after 2-3 weeks of practice. Acoustical analysis consisted of formant frequency analysis, singer's formant/singing power ratio analysis, maximum phonation frequency range analysis, and an analysis of jitter, noise to harmonic ratio (NHR), relative average perturbation (RAP), and voice turbulence index (VTI). A perceptual analysis was also conducted with 12 listeners rating comparison performances of before vs. after the vocal warm-up, before vs. after the second vocal warm-up, and after both vocal warm-ups. There were no significant findings for the formant frequency analysis of the vowel /a/, but there was significance for the 1st formant frequency analysis of the vowel /i/. Singer's formant analyzed via Singing Power Ratio analysis showed significance only for the vowel /i/. Maximum phonation frequency range analysis showed a significant increase after the vocal warm-ups. There were no significant findings for the acoustic measures of jitter, NHR, RAP, and VTI. Perceptual analysis showed a significant difference after a vocal warm-up. The results indicate that a singing vocal warm-up can have a significant positive influence on the singing voice of non-singers.

    New methods for efficient and unambiguous interconnection between electronic position sensitive detectors and target units based on nuclear photographic emulsion films have been developed. The application to the OPERA experiment, that aims at detecting ν μ ν τ oscillations 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 electronically tagged penetrating muons. Further improvement of in-doublet film alignment was obtained by matching the pattern of low-energy electron tracks. The commissioning of the overall OPERA alignment procedure is in progress

  3. 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

    The primary goal of the OPERA long-baseline neutrino oscillation experiment is the first direct detection of ν{sub μ}→ν{sub τ} oscillations. The hybrid OPERA detector consists of a large-mass target made from lead and photo emulsions - providing micrometric resolution - and electronic detector parts for online readout. It is located in the LNGS underground laboratory, at a distance of 730 km from the SPS at CERN, where the CNGS ν{sub μ} beam is produced. The measurement of ν{sub τ} appearance relies on the detection of the decay of τ leptons which are created in ν{sub τ} charged current reactions. Data acquisition lasted from 2008 to 2012. With the collected data the OPERA experiment discovered ν{sub τ} appearance in the CNGS neutrino beam with a significance of 5.1 σ. This poster will give an overview about the OPERA experiment and the discovery of τ neutrino appearance in the CNGS neutrino beam.

To prove the appearance of {nu}{sub {tau}} 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 {tau} lepton produced in {nu}{sub {tau}} 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 {nu}{sub {mu}} CC and {nu}{sub {tau}} CC with {tau} {yields} {mu} 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)

    Structure and function of the human brain are affected by training in both linguistic and musical domains. Individuals with intensive vocal musical training provide a useful model for investigating neural adaptations of learning in the vocal-motor domain and can be compared with learning in a more general musical domain. Here we confirm general differences in macrostructure (tract volume) and microstructure (fractional anisotropy, FA) of the arcuate fasciculus (AF), a prominent white-matter tract connecting temporal and frontal brain regions, between singers, instrumentalists, and non-musicians. Both groups of musicians differed from non-musicians in having larger tract volume and higher FA values of the right and left AF. The AF was then subdivided in a dorsal (superior) branch connecting the superior temporal gyrus and the inferior frontal gyrus (STG ↔ IFG), and ventral (inferior) branch connecting the middle temporal gyrus and the inferior frontal gyrus (MTG ↔ IFG). Relative to instrumental musicians, singers had a larger tract volume but lower FA values in the left dorsal AF (STG ↔ IFG), and a similar trend in the left ventral AF (MTG ↔ IFG). This between-group comparison controls for the general effects of musical training, although FA was still higher in singers compared to non-musicians. Both musician groups had higher tract volumes in the right dorsal and ventral tracts compared to non-musicians, but did not show a significant difference between each other. Furthermore, in the singers' group, FA in the left dorsal branch of the AF was inversely correlated with the number of years of participants' vocal training. Our findings suggest that long-term vocal-motor training might lead to an increase in volume and microstructural complexity of specific white-matter tracts connecting regions that are fundamental to sound perception, production, and its feedforward and feedback control which can be differentiated from a more general musician

  14. 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...

  15. Neutrino oscillations make their first appearance in OPERA

    CERN Multimedia

    CERN Bulletin

    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...

    2018-01-01

    This article combines results from three earlier investigations of the glottal voice source during phonation at varying degrees of vocal loudness (1) in five classically trained baritone singers (Sundberg et al., 1999), (2) in 15 female and 14 male untrained voices (Sundberg et al., 2005), and (3) in voices rated as hyperfunctional by an expert panel (Millgård et al., 2015). Voice source data were obtained by inverse filtering. Associated subglottal pressures were estimated from oral pressure during the occlusion for the consonant /p/. Five flow glottogram parameters, (1) maximum flow declination rate (MFDR), (2) peak-to-peak pulse amplitude, (3) level difference between the first and the second harmonics of the voice source, (4) closed quotient, and (5) normalized amplitude quotient, were averaged across the singer subjects and related to associated MFDR values. Strong, quantitative relations, expressed as equations, are found between subglottal pressure and MFDR and between MFDR and each of the other flow glottogram parameters. The values for the untrained voices, as well as those for the voices rated as hyperfunctional, deviate systematically from the values derived from the equations.

  1. 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 .

    CERN Document Server

    Duchesneau, Dominique

    2008-01-01

    OPERA (Oscillation Project with Emulsion tRacking Apparatus)is an international collaboration between Europe and Asia, aiming to give the first direct proof of tau neutrino appearance in a pure muon neutrino beam, in order to validate the hypothesis for atmospheric neutrino oscillations. The first european long baseline neutrino beam called CNGS is produced at CERN and sent in the direction of the Gran Sasso underground laboratory 730 km away, where the OPERA detector is located. Since 2006 the electronic detector part is fully commissioned and running. Cosmic ray events have been recorded on a regular basis and the first neutrino beam events have been observed in the target elements made of very precise emulsion films and lead sheets during the last run in autumn 2007. This paper reviews the status of the detector, the beam performances, the first results from the neutrino event analysis and the prospects.

    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 with much higher accuracy than previous studies conducted with accelerator neutrinos. The measurement is 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. An early arrival time of CNGS muon neutrinos with respect to the one computed assuming the speed of light in vacuum of (60.7 \\pm 6.9 (stat.) \\pm 7.4 (sys.)) ns was measured. This anomaly corresponds to a relative difference of the muon neutrino velocity with respect to the speed of light (v-c)/c = (2.48 \\pm 0.28 (stat.) \\pm 0.30 (sys.)) \\times 10-5.

    Arthur Bernard Singer was born 4 December 1917, and died 6 April 1990. Although brought up in New York City, Arthur developed an early fascination with birds. His favorite haunts were the Bronx Zoo and the American Museum of Natural History, where Robert Cushman Murphy encouraged his efforts and where Arthur acquired a worldwide perspective. After graduating from Cooper Union Art School in New York City in 1939, he began his career as an art teacher, art director, and designer, His real interest, however, was in depicting the postures and plumages of birds and mammals. As early as 1941 his wildlife art was exhibited at the Bronx Zoo. While he was in the army, his wife Edith (“Judy”) helped mount this first exhibit; Arthur never saw the show.

  9. On the Testing of Renovations Inside Historical Opera Houses

    Fausti, P.; Prodi, N.

    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.

    Previous research suggests that singing in a choir as an older adult is associated with better quality of life (QOL). However, the degree to which sociodemographic variables and level of engagement in hobbies contribute to this relationship is largely unknown. The aim of the study was to compare quality of life (QOL) of older adult choir singers with a matched sample of older adults from the general population in Finland, taking into consideration sociodemographic, satisfaction with health, and level of engagement in hobbies (active, inactive). Case-control methods were used to match a sample of 109 older adult singers with a sample of 307 older adults from the general population. Tobit regression analysis with sociodemographic covariates was used to explore observed group differences in QOL as measured by two WHOQOL-Bref domains (psychological and physical). Probit regression analysis was used to examine the effect of sociodemographic variables and engagement in hobbies and on overall QOL and satisfaction with health. As expected, sociodemographic variables were strongly associated with physical and psychological QOL. After controlling for sociodemographic variables, the older choir singers reported significantly higher ratings on physical QOL, but not psychological QOL, compared to matched controls. Additional adjustment for satisfaction for health attenuated the results. When considering level of engagement in hobbies, older adult choir singers reported significantly higher overall QOL and satisfaction with health when compared to either controls who were either actively engaged in hobbies or not active in hobbies. These results suggest that singing in a choir as an older adult may promote well-being, even after accounting for sociodemographic and level of engagement in hobbies.

    The main task of the Target Tracker detector of the long baseline neutrino oscillation OPERA experiment is to locate in which of the target elementary constituents, the lead/emulsion bricks, the neutrino interactions have occurred and also to give calorimetric information about each event. The technology used consists in walls of two planes of plastic scintillator strips, one per transverse direction. Wavelength shifting fibres collect the light signal emitted by the scintillator strips and guide it to both ends where it is read by multi-anode photomultiplier tubes. All the elements used in the construction of this detector and its main characteristics are described.

    Full Text Available This paper aims at discussing some images constituted as erotic on Brazilian television. The Brazilian soap operas Gabriela (Rede Globo, 1975, and Pantanal (Rede Manchete, 1990, and their main characters, Gabriela and Juma, will be analyzed in detail. The Veja Magazine had a most influent part in constituting such “erotic” subjects through the divulging and commenting of positive, seductive attributes on the bodies of the eroticized actresses. Gabriela and Juma are important characters because they support the stereotypes of a Brazilian sensuality and the strong mundane aspects, such as sex-appeal and dark bodies. The text explores the Brazilian television production (soap operas in order to map the images which have contributed to build the subjectively Brazilian eroticism.

    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.

    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.

    This investigation compares vocal tract dimensions and the classification of singer voices by examining an x-ray material assembled between 1959 and 1991 of students admitted to the solo singing education at the University of Music, Dresden, Germany. A total of 132 images were available to analysis. Different classifications' values of the lengths of the total vocal tract, the pharynx, and mouth cavities as well as of the relative position of the larynx, the height of the palatal arch, and the estimated vocal fold length were analyzed statistically, and some significant differences were found. The length of the pharynx cavity seemed particularly influential on the total vocal tract length, which varied systematically with classification. Also studied were the relationships between voice classification and the body height and weight and the body mass index. The data support the hypothesis that there are consistent morphological vocal tract differences between singers of different voice classifications.

    Full Text Available This study is entitled THE USES OF RELIGIOUS SYMBOL TO REPRESENT ISLAM (A Study on Religious Soap Opera Bukan Islam KTP. The background of the research is based on the facts of the arbitrary use of symbols to represent Islam shown on Indonesian televisions. 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.

  20. The Identification of High-pitched Sung Vowels in Sense and Nonsense Words by Professional Singers and Untrained Listeners.

    Science.gov (United States)

    Deme, Andrea

    2017-03-01

    High-pitched sung vowels may be considered phonetically "underspecified" because of (i) the tuning of the F 1 to the f 0 accompanying pitch raising and (ii) the wide harmonic spacing of the voice source resulting in the undersampling of the vocal tract transfer function. Therefore, sung vowel intelligibility is expected to decrease as the f 0 increases. Based on the literature of speech perception, it is often suggested that sung vowels are better perceived if uttered in consonantal (CVC) context than in isolation even at high f 0 . The results for singing, however, are contradictory. In the present study, we further investigate this question. We compare vowel identification in sense and nonsense CVC sequences and show that the positive effect of the context disappears if the number of legal choices in a perception test is similar in both conditions, meaning that any positive effect of the CVC context may only stem from the smaller number of possible responses, i.e., from higher probabilities. Additionally, it is also tested whether the training in production (i.e., singing training) may also lead to a perceptual advantage of the singers over nonsingers in the identification of high-pitched sung vowels. The results show no advantage of this kind. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

    Fries, M. D.; Fries, W. D.; McCubbin, F. M.; Zeigler, R. A.

    2018-01-01

    Mars Sample Return (MSR) requires strict organic contamination control (CC) and contamination knowledge (CK) as outlined by the Mars 2020 Organic Contamination Panel (OCP). This includes a need to monitor surficial organic contamination to a ng/sq. cm sensitivity level. Archiving and maintaining this degree of surface cleanliness may be difficult but has been achieved. MSR's CK effort will be very important because all returned samples will be studied thoroughly and in minute detail. Consequently, accurate CK must be collected and characterized to best interpret scientific results from the returned samples. The CK data are not only required to make accurate measurements and interpretations for carbon-depleted martian samples, but also to strengthen the validity of science investigations performed on the samples. The Opera instrument prototype is intended to fulfill a CC/CK role in the assembly, cleaning, and overall contamination history of hardware used in the MSR effort, from initial hardware assembly through post-flight sample curation. Opera is intended to monitor particulate and organic contamination using quartz crystal microbalances (QCMs), in a self-contained portable package that is cleanroom-compliant. The Opera prototype is in initial development capable of approximately 100 ng/sq. cm organic contamination sensitivity, with additional development planned to achieve 1 ng/sq. cm. The Opera prototype was funded by the 2017 NASA Johnson Space Center Innovation Charge Account (ICA), which provides funding for small, short-term projects.

    The present study aimed to perform a systematic literature review to assess the effects of phonation therapy on voice quality and function in singers. The systematic search was performed in February and updated in October 2017. No restriction of year, language, or publication status was applied. The primary electronic databases searched were LILACS, SciELO, PubMed, and Cochrane. Kappa coefficient was used to assess the agreement between examiners in judging article eligibility. The eligible articles were analyzed based on their risk of bias using the tools proposed by the Joanna Briggs Institute. Mendeley Desktop 1.13.3 software package (Mendeley Ltd, London, UK) was used to standardize the references of identified articles. The general sample consisted of 1965 articles screened out of the electronic databases. Two examiners analyzed the sample in the search for eligible articles. The agreement between examiners reached excellent outcomes (kappa coefficient = 0.88). After the selection, phase 6 articles remained eligible. Together, the eligible studies accounted 141 subjects (65 men and 76 women) aged between 18 and 72 years old. Electroglottography was considered as the most common method (83.33%) of assessment of the effects of phonation therapy in singers. The most prevalent exercises within the therapies were phonation into straws and phonation into glass tubes. The phonation into glass tubes immersed in water, straws, and LaxVox tubes promoted positive effects on the voice quality in singers, such as more comfortable phonation, better voice projection, and economy in voice emission.

    In this paper, we define the eta cochain form and prove its regularity when the kernel of a family of Dirac operators is a vector bundle. We decompose the eta form as a pairing of the eta cochain form with the Chern character of an idempotent matrix and we also decompose the Chern character of the index bundle for a fibration with boundary as a pairing of the family Chern-Connes character for a manifold with boundary with the Chern character of an idempotent matrix. We define the family b-Chern-Connes character and then we prove that it is entire and give its variation formula. By this variation formula, we prove another noncommutative family Atiyah-Patodi-Singer index theorem. Thus, we extend the results of Getzler and Wu to the family case.

    New methods for efficient and unambiguous interconnection between electronic counters and target units based on nuclear photographic emulsion films have been developed. 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...

    Sewing, J.

    2006-09-01

    The OPERA experiment is situated in the Gran Sasso underground laboratory. It will search for neutrino oscillation from myonneutrinos to tauneutrinos with a massive lead/emulsion target. Part of the OPERA detector is the precision tracker. This precision tracker consists of about 10000 drift tubes of 8 m length. Its purpose is to measure the muon track in the spectrometer of the OPERA detector to determine their momentum and charge. This work studies the basic properties of the precision tracker, such as the dependency of the resolution and the efficiency of the drift tubes and various parameters. These parameters are among others the high voltage and the threshold of the discriminators. The results of these studies led to suitable work parameters at that the precision tracker fulfills the requirements. Further the attenuation of a single 8 m long drift tube was measured. The software, which is used for the track reconstruction, the determination of the resolution and the efficiency was tested with computer generated data from a GEANT simulation. (orig.)

  11. American Christians for and against Parsifal: Debating the Holy Grail Opera in New York

    Directory of Open Access Journals (Sweden)

    Frederick Hale

    2017-10-01

    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.

  12. Le serie tv sono la nuova soap opera? Luci e ombre della Grande Serialità televisiva

    Directory of Open Access Journals (Sweden)

    Daniela Cardini

    2016-06-01

    Full Text Available Until a few years ago, television seriality was a secondary topic in the academic research, above all in Italy, whereas today, tv series have turned into the main interest of a lively scholarship, mostly belonging to disciplines traditionally not interested in the study of serial forms. Mutatis mutandis, today the central role of tv series is similar to the relevance of the soap opera in the critical debate in the Eighties and Nineties. From being neglected as an irrelevant part of television schedules, in a few years the soap opera turned into the symbol of a rich and polysemic textuality which quickly became the central topic of the newly-born fields of television studies and women studies. Obviously, the parallel between the soap opera and the new tv series cannot be drawn upon narrative or aesthetic dimensions, but (in the maybe provocative perspective proposed by this paper both formulas demonstrate a basic assumption of seriality: serial forms are  shaped by the mediascape they stem from. Therefore, as it happened to the soap opera, today’s academical interest for tv series shows many great opportunities and some deep contradictions, including the old matter of cultural hegemony which seems to appear once again in the evaluative attitude of some critical approaches.

  13. A Real-Time Interactive System for Facial Makeup of Peking Opera

    Science.gov (United States)

    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.

    2004-01-01

    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

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

    Arrabito, L.

    2007-10-01

    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)

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

    International Nuclear Information System (INIS)

    Heritier, C.

    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)

  1. Is OperaVOX a clinically useful tool for the assessment of voice in a general ENT clinic?

    Directory of Open Access Journals (Sweden)

    Richard Teck Kee Siau

    2017-04-01

    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. The accessibility of the software package makes it possible for a wide range of health practitioners, e.g. general ENT

  2. 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

    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.

    Full Text Available Mounting evidence suggests that musical training benefits the neural encoding of speech. This paper offers a hypothesis specifying why such benefits occur. The OPERA hypothesis proposes that such benefits are driven by adaptive plasticity in speech-processing networks, and that this plasticity occurs when five conditions are met. These are: 1 Overlap: there is anatomical overlap in the brain networks that process an acoustic feature used in both music and speech (e.g., waveform periodicity, amplitude envelope, 2 Precision: music places higher demands on these shared networks than does speech, in terms of the precision of processing, 3 Emotion: the musical activities that engage this network elicit strong positive emotion, 4 Repetition: the musical activities that engage this network are frequently repeated, and 5 Attention: the musical activities that engage this network are associated with focused attention. According to the OPERA hypothesis, when these conditions are met neural plasticity drives the networks in question to function with higher precision than needed for ordinary speech communication. Yet since speech shares these networks with music, speech processing benefits. The OPERA hypothesis is used to account for the observed superior subcortical encoding of speech in musically trained individuals, and to suggest mechanisms by which musical training might improve linguistic reading abilities.

    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.

  7. Neutrino oscillations on and off the beam: studies of the OPERA acquisition system performance

    2011-01-01

    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 OPERA neutrino oscillation experiment foresees the construction of two magnetized iron spectrometers located after the lead-nuclear emulsion targets. The magnet is made up of two vertical walls of rectangular cross section connected by return yokes. The particle trajectories are measured by high precision drift tubes located before and after the arms of the magnet. Moreover, the magnet steel is instrumented with Resistive Plate Chambers that ease pattern recognition and allow a calorimetric measurement of the hadronic showers. In this paper we review the construction of the spectrometers. In particular, we describe the results obtained from the magnet and RPC prototypes and the installation of the final apparatus at the Gran Sasso laboratories. We discuss the mechanical and magnetic properties of the steel and the techniques employed to calibrate the field in the bulk of the magnet. Moreover, results of the tests and issues concerning the mass production of the Resistive Plate Chambers are reported. Final...

    The latest Demographic and Health Surveys Report on Knowledge, Attitudes, and Practice documents an increase in the level of use of modern contraceptive methods in Tanzania between 1991 and 1994 from 5.9% to 11.3% of reproductive-age women. 53.2% of all women of reproductive age were exposed to mass media messages about family planning, which large majorities of men and women consider acceptable. 48.3% were exposed through radio, 22.9% reported listening to the US Agency for International Development-funded family planning promotional radio soap opera "Zinduka]", 22.5% read newspaper items, 17.5% saw posters, and 7.3% saw leaflets. 4.5% were visited by a family planning worker, 24.7% discussed family planning with a friend or relative, and 24.7% discussed family planning with health facility personnel. Zinduka], a popular 52-episode soap opera, depicts how the lives of Bomu wa Kabuma's family, in Msongano Town and Tawanya village in Tanzania, are affected because he is unable to provide for his eight children, parents, wife, mistress, and the mistress's child. The soap was produced with technical assistance from the Johns Hopkins University Center for Communication Programs Population Communication Services project. The 15-minute episodes were first broadcast in Swahili on Radio Tanzania from October 1993 through October 1994. The series was then resumed in September 1995 for another 12 months.

En primer lugar, se colocan en pocas palabras los propios argumentos del autor. A continuación, se analizan los "pilares" que sustentan su argumentación, intentando responder a las siguientes cuestiones: 1 ¿Es el "exceso de población" la principal causa de la pobreza? ¿podemos encontrar una relación entre pobreza y velocidad del crecimiento de la población? 2 ¿Está vigente la perspectiva demográfica que Singer asume? 3 ¿Se puede ignorar o restarle importancia al problema de la distribución de los recursos y los ingresos cuando estamos tratando el problema de la pobreza desde una perspectiva ética? 4 ¿Qué tan cierto es ese argumento del éxito en los casos de México, Colombia y Brasil en cuanto a la implantación de una política de control de la natalidad? 5 ¿Esa postura del autor sobre el crecimiento de la población tiene consecuencias negativas en el "imaginario colectivo"?

    Wonsak, B.S.

    2007-11-01

    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 χ 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 μm and an efficiency of more that 93% has been acquired. For real cosmic data from the OPERA detector a resolution o 374±3 μm 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.)

    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.

    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.

    Full Text Available Structure and function of the human brain are affected by training in both linguistic and musical domains. Individuals with intensive vocal musical training provide a useful model for investigating neural adaptations of learning in the vocal-motor domain and can be compared with learning in a more general musical domain. Here we confirm general differences in macrostructure (tract volume and microstructure (fractional anisotropy (FA of the arcuate fasciculus (AF, a prominent white-matter tract connecting temporal and frontal brain regions, between singers, instrumentalists, and non-musicians. Both groups of musicians differed from non-musicians in having larger tract volume and higher FA values of the right and left AF. The AF was then subdivided in a dorsal (superior branch connecting the superior temporal gyrus and the inferior frontal gyrus (STG<–>IFG, and ventral (inferior branch connecting the middle temporal gyrus and the inferior frontal gyrus (MTG<–>IFG. Relative to instrumental musicians, singers had a larger tract volume but lower FA values in the left dorsal AF (STG<–>IFG, and a similar trend in the left ventral AF (MTG<–>IFG. This between-group comparison controls for the general effects of musical training, although FA was still higher in singers compared to non-musicians. Both musician groups had higher tract volumes in the right dorsal and ventral tracts compared to non-musicians, but did not show a significant difference between each other. Furthermore, in the singers’ group, FA in the left dorsal branch of the AF was inversely correlated with the number of years of participants’ vocal training. Our findings suggest that long-term vocal-motor training might lead to an increase in volume and microstructural complexity of specific white matter tracts connecting regions that are fundamental to sound perception, production, and its feedforward and feedback control which can be differentiated from a more general musician

    2004-01-01

    The present document describes the front-end electronics of the RPC system that instruments the magnet muon spectrometer of the OPERA experiment. The main task of the OPERA spectrometer is to provide particle tracking information for muon identification and simplify the matching between the Precision Trackers. As no trigger has been foreseen for the experiment, the spectrometer electronics must be self-triggered with single-plane readout capability. Moreover, precision time information must be added within each event frame for off-line reconstruction. The read-out electronics is made of three different stages: the Front-End Boards (FEBs) system, the Controller Boards (CBs) system and Trigger Boards (TBs) system. The FEB system provides discrimination of the strip incoming signals; a FAST-OR output of the input signals is also available for trigger plane signal generation. FEB signals are required by the CB system that provides the zero suppression and manages the communication to the DAQ and Slow Control. A Trigger Board allows to operate in both self-trigger mode (the FEB's FAST-OR signal starts the plane acquisition) or in external-trigger mode (different conditions can be set on the FAST-OR signals generated from different planes)

  10. 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)

    Full Text Available The Dublin-born musician, Michael W. Balfe, was a singer, composerand conductor whose brilliant musical career was heavily influenced byformative experiences in Italy. In 1825, Balfe, interested in broadeninghis musical studies first went to Paris where he was introduced to thegreat composers, Luigi Cherubini and Gioachino Rossini, who took apersonal interest in him and his musical talents. On the advice of Rossinihe spent the next few years in Italy studying singing with the famousRossini singer, Filippo Galli, and taking music composition lessonsfrom Ferdinando Paer, in Rome. Later in Milan he studied harmonyand counterpoint with Vincenzo Federici. By 1831, when he was only23 years old, his first three operas had been produced in Palermo, Pavia,and Milan. He returned to London in August 1835, participatingwith the great Lablache, Tamburini, Rubini and Grisi in a concert inVauxhall Gardens. In 1834 he made his debut at La Scala, Milan, singingopposite the renowned mezzo-soprano, Maria Malibran in Rossini’sOtello. He appeared again with Malibran in Venice early in 1835,singing once more in Rossini and Bellini operas.

    2012-09-01

    OPERA, the oscillation project with emulsion-tracking apparatus, is a long-baseline neutrino oscillation experiment. It combines an almost pure, high-energy ν μ beam produced at the SPS accelerator at CERN, Switzerland, with the OPERA neutrino detector located at a distance of about 730 km in the LNGS underground laboratory in Italy. By using a lead/photo emulsion target, ν τ charged current (CC) interactions of ν τ from ν μ → ν τ oscillations can be observed on an event-by-event basis with very low background rates. Within this thesis, a ν μ →ν μ disappearance search is described that uses a flux normalization. independent measurement of the CC event fraction as a function of the hadronic energy as measured by the electronic detectors of OPERA. This allows to derive limits on ν μ →ν μ oscillations, complementary to the main ν τ appearance analysis. For maximal mixing, vertical stroke Δm 2 23 vertical stroke >4.4 x 10 -3 eV 2 is excluded at 90% C.L. by the disappearance analysis. This thesis represents the first application of this method, including systematic uncertainties, in a long-baseline neutrino oscillation experiment.

    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.

    The research material is mostly based on the works of Albert Lord and Milman Parry, Karl Reichl, Ilhan Basgoz, Pertev Boratav. Epic singers played a significant part in spreading national spirit, be it Turkish or Slavic. The Balkan artists called guslar used a one-string instrument called gusle while a Turkish minstrel ozan and ashik usually used a two-stringed instrument called kopuz or saz. The typical stage for their activities were coffeehouses. Oral epics were transmitted by word of mouth from one singer to another, sometimes by way of formal training based on the transmission of repertoire and technique from master to apprentice. Representative of both traditions was the use of metrics and formulaic style. The song was orally composed in performance, with the audience’s participation. The musical aspect facilitated memorisation. The text to be learned by heart was a story in a song. Although the Turkish and Balkan epic traditions developed independently of each other, the effect of Turkish conquest on the Balkan epic tradition is evident, especially in the style of those singers who perform in borderland (in Kosovo and northern Albania. The Turkish occupation itself became the subject of many epics, reinforcing the national identity of the local population. However, oriental influences also emerged in some formal characteristics, such as the length of the songs, the ornamentation and stylised oriental images and the transformation of separate ballads and short narratives into epic cycles. In both cases for performers themselves this artistic activity became “a way of life”.

    The OPERA detector, designed to search for 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 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, 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 TeV/nucleon primary energy.

  5. How a professional interest of scientists for music has helped to develop geoethics and cross-cultural differences exchange

    2014-05-01

    Let us start with a story of the conservatory in Prague where a Czech student Jan Snitil met a Japanese girl Masako Nakajima. Their marriage helped to initiate a cultural exchange between their countries of birth. Later Jan Snitil as the conductor of the Opera house in Opava with the help of a NPO group under his wife had a considerable success in introducing the Czech opera Dalibor (from Bedrich Smetana; stage director Josef Novak) in Japan and by realizing the first performance of the Japanese opera "Juzuru" (stage director T. Ohska) in Opava. This brought together both respective stage directors. The intensifying interest of T. Ohska for the operas of Smetana inspired J. Novak to arrange in Prague his meeting with Vaclav Nemec well known for his promotion work of the great Czech composer. In his professional career Vaclav Nemec is the internationally known Earth scientist specialized since early 1960's in the field of mathematical geology (later also in tectonics) and since 1991 respected as the "Father of Geoethics". At the meeting Nemec recognized Ohska as a Physics Professor specialized in nuclear physic and attracted him for an active participation in the field of geoethics. Prof. Ohska prepared valuable presentations for the international session on geoethics at Pribram (2011) and especially for the International Geological Congress in Brisbane (2012). At Pribram in the course of a social party Lidmila Nemcova (co-convenor of the meeting) introduced Prof. Ohska to Waclaw Demecki, Chancellor of the Higher School of Management in Legnica (Poland). Demecki has been inviting Ohska for special lectures on science as well as on cultural heritage of Japan. Professor Ohska arranges his visits to Poland through Prague where he can meet with Novak and Nemec to discuss the staging of the last opera of Smetana "Devil's Wall". Nemec in his research had finally deciphered (2012, i.e. 130 years after the first performance) the "mystery" of this opera: the composer put

    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.

    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.

    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)

    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.

  12. OPERA, an automatic PSF reconstruction software for Shack-Hartmann AO systems: application to Altair

    Science.gov (United States)

    Jolissaint, Laurent; Veran, Jean-Pierre; Marino, Jose

    2004-10-01

    When doing high angular resolution imaging with adaptive optics (AO), it is of crucial importance to have an accurate knowledge of the point spread function associated with each observation. Applications are numerous: image contrast enhancement by deconvolution, improved photometry and astrometry, as well as real time AO performance evaluation. In this paper, we present our work on automatic PSF reconstruction based on control loop data, acquired simultaneously with the observation. This problem has already been solved for curvature AO systems. To adapt this method to another type of WFS, a specific analytical noise propagation model must be established. For the Shack-Hartmann WFS, we are able to derive a very accurate estimate of the noise on each slope measurement, based on the covariances of the WFS CCD pixel values in the corresponding sub-aperture. These covariances can be either derived off-line from telemetry data, or calculated by the AO computer during the acquisition. We present improved methods to determine 1) r0 from the DM drive commands, which includes an estimation of the outer scale L0 2) the contribution of the high spatial frequency component of the turbulent phase, which is not corrected by the AO system and is scaled by r0. This new method has been implemented in an IDL-based software called OPERA (Performance of Adaptive Optics). We have tested OPERA on Altair, the recently commissioned Gemini-North AO system, and present our preliminary results. We also summarize the AO data required to run OPERA on any other AO system.

    Full Text Available Although the last three decades have seen a steady rise in the perceived importance of operations strategy together with its corresponding literature base, one could argue that it has not yet reached its full potential. This paper reviews some of the reasons why this may be. It starts by briefly examining the importance of operations strategy within the broader operations management area and then examines some challenges to the subject under two headings. The first heading concerns whether operations strategy accurately reflects the nature of 'operations' within the economy. The second heading examines some of the challenges in making any operations-based topic into one that has strategic relevance. Finally, a number of prescriptions are put forward that may allow the development of the subject to answer some of the challenges posed.Embora nas últimas três décadas tenha sido constatado um constante crescimento na percepção de importância da área de estratégia de operações, juntamente com a sua respectiva base literária, pode-se argumentar que ela ainda não atingiu todo o seu potencial. Este artigo revisa algumas das razões pelas quais isto pode estar ocorrendo. Inicialmente, a importância da estratégia de operações dentro da área mais ampla de gestão de operações é analisada de forma sucinta e em seguida, alguns desafios são explorados em duas vertentes. A primeira trata se estratégia de operações reflete precisamente a natureza das operações dentro da economia. A segunda explora alguns dos desafios em tornar tópicos relacionados a operações em tópicos com importância estratégica. Por fim, são propostas algumas prescrições que podem apoiar o desenvolvimento da área de modo a responder a alguns dos desafios apresentados.

    2018-01-11

    The objectives of this study were to trace and describe research patterns in singing voice, to compare the amount of published research over time, to identify journals that published most papers on "singing voice," and to establish the most frequent research topics. The study uses qualitative and quantitative approaches through descriptive statistics, text mining, and clustering. The authors conducted a search to identify scientific papers. The titles and abstracts were analyzed regarding word frequency and relations between them, through hierarchical cluster analysis and co-occurrence networks. The frequency of journals was calculated, as well as the amount of papers across time. Since 1949, 754 papers were published and an increase was noticed. Even though 162 journals were identified by the authors, the Journal of Voice holds the majority of papers, in every analyzed period. An evolution of studied topics is described. Up to 2010, the main theme was professional singers, especially classical and opera interpreters. Since then, voice quality and the effects of training gathered more attention. The growing interest in singing has been conspicuous since the first indexed paper. However, it has been slightly slowing down. Until 2010, great importance was given to the voice quality of singers and their occupational demands. Acoustic analysis was widely used to study the effects of training. Since 2010, the concern with functionality is increasing, rather than the organic voice structures. Musical perception studies have been a trend, as well as the use of electroglottography.

    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...

    Throughout his career, from The Boys Next Door, through The Birthday Party, and with The Bad Seeds, Australian singer / songwriter Nick Cave has balanced his own set of creative voices alongside those of others through his choice of cover versions. Cave’s 1986 album with The Bad Seeds, ‘Kicking Against the Pricks’, is a collection of cover versions that spans American folk idioms (‘Black Betty’, ‘Hey Joe’, ‘The Singer’), Tin-Pan-Alley balladeering (‘Something’s Gotten Hold of my Heart’, ‘By t...

    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.

  2. Study of v interactions and background estimation in the OPERA emulsion film detector

    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...

  3. Eastern naturalness versus western artificiality: Rimsky Korsakov's influence on Manoles Kalomoires' early operas

    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.

    A highly localized data-association measure, termed intrinsic synchrosqueezing transform (ISC), is proposed for the analysis of coupled nonlinear and non-stationary multivariate signals. This is achieved based on a combination of noise-assisted multivariate empirical mode decomposition and short-time Fourier transform-based univariate and multivariate synchrosqueezing transforms. It is shown that the ISC outperforms six other combinations of algorithms in estimating degrees of synchrony in synthetic linear and nonlinear bivariate signals. Its advantage is further illustrated in the precise identification of the synchronized respiratory and heart rate variability frequencies among a subset of bass singers of a professional choir, where it distinctly exhibits better performance than the continuous wavelet transform-based ISC. We also introduce an extension to the intrinsic phase synchrony (IPS) measure, referred to as nested intrinsic phase synchrony (N-IPS), for the empirical quantification of physically meaningful and straightforward-to-interpret trends in phase synchrony. The N-IPS is employed to reveal physically meaningful variations in the levels of cooperation in choir singing and performing a surgical procedure. Both the proposed techniques successfully reveal degrees of synchronization of the physiological signals in two different aspects: (i) precise localization of synchrony in time and frequency (ISC), and (ii) large-scale analysis for the empirical quantification of physically meaningful trends in synchrony (N-IPS).

    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.

  9. Silent music reading: auditory imagery and visuotonal modality transfer in singers and non-singers.

    In daily life, responses are often facilitated by anticipatory imagery of expected targets which are announced by associated stimuli from different sensory modalities. Silent music reading represents an intriguing case of visuotonal modality transfer in working memory as it induces highly defined auditory imagery on the basis of presented visuospatial information (i.e. musical notes). Using functional MRI and a delayed sequence matching-to-sample paradigm, we compared brain activations during retention intervals (10s) of visual (VV) or tonal (TT) unimodal maintenance versus visuospatial-to-tonal modality transfer (VT) tasks. Visual or tonal sequences were comprised of six elements, white squares or tones, which were low, middle, or high regarding vertical screen position or pitch, respectively (presentation duration: 1.5s). For the cross-modal condition (VT, session 3), the visuospatial elements from condition VV (session 1) were re-defined as low, middle or high "notes" indicating low, middle or high tones from condition TT (session 2), respectively, and subjects had to match tonal sequences (probe) to previously presented note sequences. Tasks alternately had low or high cognitive load. To evaluate possible effects of music reading expertise, 15 singers and 15 non-musicians were included. Scanner task performance was excellent in both groups. Despite identity of applied visuospatial stimuli, visuotonal modality transfer versus visual maintenance (VT>VV) induced "inhibition" of visual brain areas and activation of primary and higher auditory brain areas which exceeded auditory activation elicited by tonal stimulation (VT>TT). This transfer-related visual-to-auditory activation shift occurred in both groups but was more pronounced in experts. Frontoparietal areas were activated by higher cognitive load but not by modality transfer. The auditory brain showed a potential to anticipate expected auditory target stimuli on the basis of non-auditory information and

  11. Something in the Air: Dr Carter Moffat’s Ammoniaphone and the Victorian Science of Singing

    Directory of Open Access Journals (Sweden)

    Dr Melissa Dickson

    2017-04-01

    Full Text Available In January 1885, the Glaswegian Professor of Chemistry Dr Robert Carter Moffat organised a special operatic concert at St James’s Hall, London, to which he invited around two thousand scientists and musicians. The point of this invitation concert was that all the singers used bottled air. Moffat himself appeared between the various performances, wielding his mysterious Ammoniaphone, or bottled-air machine, a long silver tube which he flourished in the faces of his audience while describing its virtues with considerable animation. The premise of the Ammoniaphone was that since Italian opera singers were known throughout the world for the beauty of their voices, it stood to reason that this must have something to do with the quality of the air they breathed. The Ammoniaphone, Moffat claimed, contained the precise chemical formula of the air in Southern Italy, and inhaling from this instrument effectively resulted in the ‘Italianization of the voice’. Drawing on representations of the Ammoniaphone across nineteenth-century advertising and the medical and musical press, and situating these representations within the broader Victorian fascination with the supremacy of Italian opera singers, this essay offers new insight into the emergent corporeal anxieties betrayed by late nineteenth-century consumer culture, and the various methods by which the body might be continually fashioned and re-fashioned in order to produce a high-functioning social subject in a fast-paced modern society. Aggressively (not to say unscrupulously advertised, the Ammoniaphone was marketed to vocalists, clergymen, public speakers, choirmasters, schoolmasters, parliamentarians, and enthusiastic amateurs of these vocations, with claims that it would conserve and preserve the voice, expand its range upwards and downwards, and lend it an otherwise unobtainable purity, beauty and richness. This, I will argue, was symptomatic of a broader cultural need to counter the stresses

  12. Politics in the context of the “Opera question” in the national theatre before the first world war

    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. The context of

SOPRANO computes electromagnetic fields at high frequency including displacement current effects. It has 2 modules emdash a deterministic solution at a user defined frequency and an eigenvalue solution for modal analysis. It is suitable for designing microwave structures and cavities found in particle accelerators. SCALA computes electrostatic fields in the presence of space charge from charged particle beams. The user may define the emission characteristics of electrodes or plasma surfaces and compute the resultant space charge limited beams, including the presence of magnetic fields. Typical applications in particle accelerators are electron guns and ion sources. Other enhancements to the suite include additional capabilities in TOSCA and ELEKTRA, the static and dynamic solvers. copyright 1997 American Institute of Physics

    Sisakun, Siphan

    2000-12-01

    The purpose of this study is to explore the ability of four acoustic parameters, mean fundamental frequency, jitter, shimmer, and harmonics-to-noise ratio, to detect vocal fatigue in student singers. The participants are 15 voice students, who perform two distinct tasks, data collection task and vocal fatiguing task. The data collection task includes the sustained vowel /a/, reading a standard passage, and self-rate on a vocal fatigue form. The vocal fatiguing task is the vocal practice of musical scores for a total of 45 minutes. The four acoustic parameters are extracted using the software EZVoicePlus. The data analyses are performed to answer eight research questions. The first four questions relate to correlations of the self-rating scale and each of the four parameters. The next four research questions relate to differences in the parameters over time using one-factor repeated measures analysis of variance (ANOVA). The result yields a proposed acoustic profile of vocal fatigue in student singers. This profile is characterized by increased fundamental frequency; slightly decreased jitter; slightly decreased shimmer; and slightly increased harmonics-to-noise ratio. The proposed profile requires further investigation.

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

    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

    Full Text Available http://dx.doi.org/10.5007/1677-2954.2009v8n1p9 Peter Singer’s views on the status of animals, the sanctity of human life, and world poverty have attracted both attention and intense controversy in many Western countries, including the United States, Canada, and Germany. The reactions in France to his theories are less well-known. The purpose of this paper is to present an overview of critical responses to Singer by French academics and thinkers. How have they received Singer’s contention that we must bring nonhuman animals within the sphere of moral concern? How has his claim been received according to which we must recognize that the worth of human life varies? Do French scholars agree with his utilitarian views on abortion, euthanasia, infanticide, his defi nition of the term “person”? Finally, is he considered in France as a brilliant and groundbreaking ethicist, as a dangerous extremist, or somewhere in between

    2009-01-01

    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.

  3. Atiyah-Patodi-Singer index from the domain-wall fermion Dirac operator

    2017-12-01

    The Atiyah-Patodi-Singer (APS) index theorem attracts attention for understanding physics on the surface of materials in topological phases. The mathematical setup for this theorem is, however, not directly related to the physical fermion system, as it imposes on the fermion fields a nonlocal boundary condition known as the "APS boundary condition" by hand, which is unlikely to be realized in the materials. In this work, we attempt to reformulate the APS index in a "physicist-friendly" way for a simple setup with U (1 ) or S U (N ) gauge group on a flat four-dimensional Euclidean space. We find that the same index as APS is obtained from the domain-wall fermion Dirac operator with a local boundary condition, which is naturally given by the kink structure in the mass term. As the boundary condition does not depend on the gauge fields, our new definition of the index is easy to compute with the standard Fujikawa method.

    Full Text Available Insegnare l’opera lirica agli studenti di Musicologia non è più difficile che insegnare altre materie nell’àmbito della Storia della musica. Certo, per fare un buon lavoro occorre conoscere la letteratura, il teatro, le voci, la scenografia. Del resto, anche per insegnare dignitosamente il canto gregoriano si deve conoscere a fondo il latino, la storia della liturgia, la storia dell’arte eccetera. Siamo professionisti: sappiamo bene cos’è importante per noi – ci lavoriamo direttamente o attraverso i nostri studenti –, eppure non mancano gli studi in cui non crediamo molto. Volendo essere obiettivi, facciamo tuttavia del nostro meglio per far conoscere tutti gli studi di alto livello, senza dare giudizi negativi, al fine di preparare i nostri studenti alle diverse possibilità offerte dalla carriera professionale: potranno avere a che fare con i frequentatori degli archivi, con coloro che s’interessano soprattutto di drammaturgia, con i fans della new musicology, o con quei poverini che redigono edizioni critiche.

  6. Upstream from OPERA: extreme attention to detail

    CERN Multimedia

    CERN Bulletin

    2011-01-01

    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...

    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 $\\sim$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 $\\delta t_\

  13. "Exoticism” in the opera Gilgamesh by Rudolf Brucci in Ralph Locke’s “All the music in the full context” paradigm

    Directory of Open Access Journals (Sweden)

    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

  16. Les implications du travestissement dans I Capuleti e i Montecchi de Vincenzo Bellini The Implications of the Transvestite Part in Vincenzo Bellini’s I Capuleti e i Montecchi

    Directory of Open Access Journals (Sweden)

    Isabelle Schwartz-Gastine

    2009-11-01

    Full Text Available My concern for transvestite parts stems from the Shakespearean drama conventions in which all female roles were performed by young men and apprentice boys for decency’s sake. Bellini and Felice Romani, his librettist, were certainly not influenced by the English bard, but by a common source, book 4 of Ovid’s Metamorphoses, when they composed the score and lyrics of their opera in the 1820s. According to baroque Italian operatic conventions, the part of the lover should have been performed by a castrato so that his voice could merge perfectly with that of the soprano heroine. However Bellini preferred a female singer, Giuditta Grisi, who specialised in a repertoire of young male lovers called musico, to play against her own sister, Giulia, as Julietta. Both women met with great success as appears from contemporary reviews, which praise their vocal performances but ignore the change from the tradition of the castrato, as well as the physicality of the show. An analysis of some photographs from a series of recent productions of the opera sheds some light on this visual dimension and on the choices made by several stage directors in their own approach to the opera.

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

    International Nuclear Information System (INIS)

    Brunetti, G.

    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.

  19. Describing different styles of singing: a comparison of a female singer's voice source in "Classical", "Pop", "Jazz" and "Blues".

    The voice is apparently used in quite different manners in different styles of singing. Some of these differences concern the voice source, which varies considerably with loudness, pitch, and mode of phonation. We attempt to describe voice source differences between Classical, Pop, Jazz and Blues styles of singing as produced in a triad melody pattern by a professional female singer in soft, middle and loud phonation. An expert panel was asked to identify these triads as examples of either Classical, Pop, Jazz or Blues. The voice source was analysed by inverse filtering. Subglottal pressure Ps, closed quotient QClosed, glottal compliance (ratio between the air volume contained in a voice pulse and Ps), and the level difference between the two lowest source spectrum partials were analysed in the styles and in four modes of phonation: breathy, flow, neutral, and pressed. The same expert panel rated the degree of pressedness in the entire material. Averages across pitch were calculated for each mode and style and related to their total range of variation in the subject. The glottogram data showed a high correlation with the ratings of pressedness. Based on these correlations a pressedness factor was computed from the glottogram data. A phonation map was constructed with the axes representing mean adduction factor and mean Ps, respectively. In this map Classical was similar to flow phonation, Pop and Jazz to neutral and flow phonation, and Blues to pressed phonation.

  1. Prince of zeta by Petar Konjović: Opera in five/four acts on the 125th anniversary of the composer's birth

    2008-01-01

    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

    Most agree that education about vocal health and physiology can help singers avoid the development of vocal disorders. However, little is known about how this kind of education is provided to singers as part of their formal training. This study describes the amount of instruction in these topics provided through graduate-level curricula, who provides this instruction, and the kinds of affiliations such graduate singing programs have with medical professionals. This is an online survey of music schools with graduate singing programs. Survey questions addressed demographics of the programs, general attitudes about vocal health instruction for singers, the amount of vocal health instruction provided and by whom it was taught, perceived barriers to including more vocal health instruction, and any affiliations the voice program might have with medical personnel. Eighty-one survey responses were received. Instruction on vocal health was provided in 95% of the schools. In 55% of the schools, none of this instruction was given by a medical professional. Limited time in the curriculum, lack of financial support, and lack of availability of medical professional were the most frequently reported barriers to providing more instruction. When programs offered more hours of instruction, they were more likely to have some of that instruction given by a medical professional (P = 0.008) and to assess the amount of instruction provided positively (P = 0.001). There are several perceived barriers to incorporating vocal health education into graduate singing programs. Opportunity exists for more collaboration between vocal pedagogues and medical professionals in the education of singers about vocal health. Copyright © 2017 The Voice Foundation.

  4. 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)

    This study investigated the susceptibility of American singer canaries ( Serinus canaria) to West Nile virus (WNV) infection. Adult canaries were inoculated with 10 5 , 10 2 , and 10 1 plaque forming units (PFU) of WNV. All birds became infected and mortality occurred by 5 days postinoculation. The load of viral RNA as determined by RT-qPCR was dose dependent, and was higher at all doses than the level of viral RNA detected in American crows ( Corvus brachyrhynchos) challenged with 10 5 PFU of WNV. In a subset of birds, viremia was detected by virus isolation; canaries inoculated with 10 1 PFU of WNV developed viremia exceeding 10 10 PFU/mL serum, a log higher than American crows inoculated with 10 5 PFU of virus. In canaries euthanized at 3 days postinoculation, WNV was isolated at >10 7 PFU of virus/100 mg of lung, liver, heart, spleen, and kidney tissues. Pallor of the liver and splenomegaly were the most common macroscopic observations and histologic lesions were most severe in liver, spleen, and kidney, particularly in canaries challenged with 10 2 and 10 1 PFU. Immunoreactivity to WNV was pronounced in the liver and spleen. IgG antibodies to WNV were detected in serum by enzyme immunoassay in 11 of 21 (52%) challenged canaries and, in 4 of 5 (20%) of these sera, neutralization antibodies were detected at a titer ≥ 1:20. American singer canaries provide a useful model as this bird species is highly susceptible to WNV infection.

    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 sho...

  8. John Piper et Benjamin Britten : le renouveau de l’opéra anglais et ses décors John Piper and Benjamin Britten: backdrops to the renaissance of english opera

    Directory of Open Access Journals (Sweden)

    Sophie Aymès

    2009-10-01

    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.

    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.

    Full Text Available A cirurgia de Gleen bidirecional tem sido empregadacomo uma opção ao tratamento cirúrgico de pacientes considerados candidatos "não ideais" à cirurgia de derivação átrio-pulmonar. A operação consiste na anastomose da veia cava superior com a artéria pulmonar (anastomose término-lateral, permitindo o fluxo sanguíneo também para o pulmão contra-lateral. A partir de janeiro de 1990 até fevereiro de 1992, 20 pacientes foram operados em nosso Serviço, com idade variando de 5 meses a 8 anos (média de 37,7 meses. Oito pacientes eram do sexo feminino e o peso variou de 6,3 a 18,8 Kg (média - 12,4 kg. A indicação cirúrgica foi considerada primária em 10 casos. Sete casos de atresia tricúspide e 3 de ventrículo único, que apresentavam acentuada diminuição do fluxo pulmonar e não eram candidatos a correção total funcional. Os demais pacientes tiveram a indicação considerada secundária, ou seja, já haviam sido submetidos a operação de shunt artério-venoso, cerclagem do tranco pulmonar, ou atriosseptostomia, 8 casos de atresia tricúspide, 3 de ventrículo único com estenose ou cerclagem pulmonar e 1 caso de DVSVD com ventrículo superior-inferior. A operação foi realizada com desvio da veia cava-átrio direito em 12 casos e com o uso de CEC em 8. Durante o procedimento cirúrgico, os pacientes foram monitorizados com oxímetro pulsátil e a saturação de oxigênio média pré-correção foi de 75,5% (71% a 86% e após, de 95% (91% a 98%. Não ocorreu óbito hospitalar e o único óbito tardio foi devido a infecção pulmonar no 2º mês de pós-operatório. Achamos, portanto, que a operação de Glenn bidirecional estará bem indicada como primeira etapa da correção definitiva, pois não aumenta o trabalho cardíaco e a resistência vascular pulmonar não produz distorções em artéria pulmonar como shunt tipo Blalock-Taussig.The bidirectional Glenn anastomosis has bee used as an effective mean of palliating

    A phoniatrist analyzes the professional's voice at the beginning of his vocal studies or career but also later, in cases of voice disorder. Phoniatric examination of professional singers must be done according to "all inclusive" protocols of examination. Such protocols must establish the status of basic elements of phonatory system: activator, generator and resonator of voice and articulatory space. All patients requiring phoniatric examination no matter if they are candidates for professional singers, need to provide anamnestic data about their previous problems regarding voice or singing. This examination is necessary and it must include: examination of nose, cavum oris, pharynx, ears and larynx. This analysis is based on evaluation of physiological and pathophysiological manifestations of voice. Determination of musical voice range during phoniatric examination does not intend to make any classification of voice, nor to suggest to vocal teacher what he should count upon from future singers. Musical range can be determined only by a phoniatrist skilled in music or with musical training, but first of all vocal teacher. These methods are used for examination of phonatory function, or laryngeal pathology. They are not invasive and give objective and quantitative information. They include: laryngostroboscopy, spectral analysis of voice (sonography) and fundamental parameters of voice signal (computer program). Articulation is very important for solo singers, because good articulation contributes to qualitative emission of sound and expression of emotions. Tonal-threshold audiometry is performed as a hearing test. They include rhinomanometry, vital capacity measurements, maximal phonation time and phonation quotient. Phoniatric examination is a necessary proceeding which must be performed before admission to the academy of solo singing, and then during singers' education and career. The phoniatric protocol must include a minimal number of parameters, which can be

    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.

  18. Shakespeare Re-Read, Re-Written, Re-Contextualised Or... Re-Placed in Opera and Musical

    Directory of Open Access Journals (Sweden)

    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 OBJETIVO: identificar possíveis problemas vocais enfrentados por cantores evangélicos de Irati-PR. MÉTODO: foram analisados 42 questionários respondidos por cantores de Igreja, onde constavam dados de identificação e um questionário referente a 30 problemas vocais que poderiam ser enfrentados pelos cantores, tanto referentes aos problemas de saúde vocal, quanto relacionados à utilização específica da voz cantada. O questionário já é amplamente utilizado na literatura brasileira. RESULTADOS: a média de problemas referidos foi de 7,78. Mulheres referiram maior quantidade média de problemas vocais (média:9,65 do que homens (média:6,19, havendo diferença estatisticamente significante entre eles (p=0,03. Das 30 questões, apenas uma não foi assinalada por nenhum cantor. Os problemas vocais mais citados foram: dificuldades para atingir notas agudas ou graves (n=29;58%, falta de ar para terminar frases musicais (n=27;54%, sensação de aperto ou bola na garganta (n=25;50%, sensação de voz fraca ou forte demais para o canto coral (n=22;44%, e desafinação (n=18;42%. Além disso, foi possível observar que não houve aumento de problemas vocais com o avanço da idade ou do tempo de canto (p=0,003 e p=0,573, respectivamente. CONCLUSÃO: mulheres referiram mais problemas do que homens no que se refere à utilização da voz no canto coral. A quantidade de problemas vocais independeu da idade e do tempo de canto, o que pode indicar que a falta de técnica pode ser prejudicial até mesmo para indivíduos que cantam há pouco tempo. As queixas mais frequentes parecem ter maior relação com a falta de técnica vocal.PURPOSE: to identify possible problems faced by gospel singers of Irati-PR.

    The OPERA experiment was designed to study νμ→ντ oscillations in the appearance mode in the CERN to Gran Sasso Neutrino beam (CNGS). In this Letter, we report the final analysis of the full data sample collected between 2008 and 2012, corresponding to 17.97×1019 protons on target. Selection criteria looser than in previous analyses have produced ten ντ candidate events, thus reducing the statistical uncertainty in the measurement of the oscillation parameters and of ντ properties. A multivariate approach for event identification has been applied to the candidate events and the discovery of ντ appearance is confirmed with an improved significance level of 6.1σ. |Δm322| has been measured, in appearance mode, with an accuracy of 20%. The measurement of the ντ charged-current cross section, for the first time with a negligible contamination from ν¯τ, and the first direct evidence for the ντ lepton number are also reported.

    city of Recife. This is an observational, transversal and descriptive study. With consent of 13 singers, above 18-year old, there was recording of the spoken voice while speaking vowel as well during the song "happy birthday"; as for singing voice, there was recording through songs from singer's repertory. RESULTS: times of speech reduced; pitch and loudness modifications, comparing spoken and singing voice, both were adequate but changed into sharp and high, respectively; changes in resonance, of laryngeal-pharyngeal type to balanced with nasal compensation. There was maintenance of the brusque vocal attack; change of the mixed modal register in habitual voice to head modal in professional voice; clear vocal quality predominance in spoken voice and patterns adequate to modulation, projection and articulation in singing. CONCLUSION: the singers from kitschy musical style in Recife had reduced maximum phonation time and had, in the speech voice to singing voice, changes in pitch, loudness and resonance and maintenance of vocal characteristics for attack and recording. A clear voice quality in speech voice was predominant and the appropriate modulation, good projection and good articulation were among the most frequent patterns in singing voice.

    1990-01-01

    The author describes the events surrounding his attempts to lecture on the subject of euthanasia in West Germany in June 1989. Singer, who defends the view that active euthanasia for some newborns with handicaps may be ethically permissible, had been invited to speak to professional and academic groups. Strong public protests against Singer and his topic led to the cancellation of some of his engagements, disruptions during others, and harrassment of the German academics who had invited him to speak. These incidents and the subject of euthanasia became matters of intense national debate in West Germany, but there was little public or academic support for Singer's right to be heard. Singer argues that bioethics and bioethicists must have the freedom to challenge conventional moral beliefs, and that the events in West Germany illustrate the grave danger to that freedom from religious and political intolerance.

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.)

    Full Text Available This paper examines the role played by opera during the nineteenth century in Mexico and Brazil, with views to start a joint reflection on these two Latin American countries based on the career of two musicians: the Brazilian Carlos Gomes and the Mexican Melesio Morales. This essay does not aspire to be a paper on comparative history, let alone on musicology. It rather  seeks to sketch an anal- ysis in the line of the “connected histories” introduced by Sanjay Subrahmanayam. My starting points are the bonds that tied Mexico, Brazil and Italy during the nineteenth century in the field of opera. The rivalry between these two musicians made us bring together and relate two rarely compared histories, two pasts, and two historiographies.

    Full Text Available O mercado de derivativos vem ganhando importância no contexto econômico mundial, demandando procedimentos contábeis que evidenciem corretamente os riscos e os benefícios envolvidos em tais operações. Desta maneira, este artigo mostra e discute aspectos da contabilização de operações de hedge, utilizando como base para análise, dois instrumentos utilizados com a finalidade de hedge no agronegócio brasileiro: a Cédula de Produto Rural (CPR e os contratos futuros agropecuários. Através de pesquisa bibliográfica, foram estudados os procedimentos do Hedging Accounting, segundo a normatização do FASB, e da CVM. Através do desenvolvimento de um exemplo teórico foram analisados e discutidos estes procedimentos, comparando as divergências de critérios entre as normas dos dois órgãos citados, e o impacto destes na análise das demonstrações financeiras tanto do produtor rural como da agroindústria. Esta análise demonstra que há divergências significativas na evidenciação destes instrumentos, principalmente dos contratos futuros, entre as normas analisadas. Ja para a CPR, foi proposta uma contabilização segundo o conceito de "derivativo embutido", conceito este contemplado pelo próprio FASB para alguns contratos com características híbridas. Existe uma necessidade de adequação das normas da CVM ao FASB, visto a importância de evidenciar estas operações no "corpo"do balanço, tanto no aspecto de exposição ao risco, como para a comparando de estratégias diferentes de proteção. No entanto, analisando somente dois títulos, fica evidente a dificuldade da adequação das normas brasileiras ao FASB.

Los escritores noveles aparecen ya en la ficción airiana de los años 90 (en El volante, por ejemplo, pero su frecuencia aumenta en las novelas de la década siguiente (Varamo, El mago, Parménides, La vida nueva. Por muy distintos que sean los protagonistas de todas estas novelas, los planteos que surgen al narrar cómo cada uno de ellos se convierte en escritor guardan una estrecha relación con la poética del propio César Aira. La figuración de la escritura de una opera prima prolonga y completa una reflexión ya iniciada anteriormente, por ejemplo en el diálogo que las primeras novelas de Aira entablan con los textos fundadores de la literatura argentina, en el diálogo con el Génesis bíblico propuesto por El congreso de literatura y en las páginas que El vestido rosa consagra a la cuestión del comienzo de la ficción, páginas que Diario de la hepatitis y Fragmento de un diario en los Alpes desarrollan y enriquecen en las décadas siguientes.La figuration de l’écriture d’une opera prima est une des formes adoptées par la réflexion sur le commencement dans la fiction de de César Aira.

    2000-04-01

    In room acoustics, many objective parameters to quantify subjective impressions have been introduced. These quantities can be measured by using a wide variety of powerful tools and equipment. The results can be influenced by the measurement techniques and instruments used. Furthermore, the results also depend on the measurement positions and on the condition of the hall (full, empty, etc.). The aim of this work is to define a tightly standardized measurement procedure for the collection of a complete objective description of an opera house's acoustics. In this paper some of the results obtained by the authors after measurements made in three different halls are presented. Comparisons were made both between different hardware and software tools (real-time analyzer, DAT, PC-board, source, microphones, post-processing software) and between different measurement methods (interrupted stationary noise, true-impulse, pseudo-random white noise with impulse-response doconvolution, sine sweep) as well as between different positions in the halls, with and without the presence of musicians and audience. The results have shown that the differences obtained when using different measurement techniques and equipment are not of significant importance. The only effective differences were found regarding the recording techniques, as the monaural measurements give appreciably different results from the average of left and right channel of binaural measurements. Slightly different results were alsofound between true impulsive sources (pistol shots, balloons) and omni-directional (dodecahedral) loudspeakers. Attention must be paid to the signal-to-noise ratio, as this can influence the correct calculation of some acoustical parameters. Some differences, not as great as expected, were found in the results with and without the musicians in the orchestra shell and with and without the audience in the hall. This is probably due to the high sound absorption that is typical in Italian opera

    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 Resumo Atualmente é observado um crescimento de iniciativas independentes para a implantação de sistemas prediais de água não potável em edifícios residenciais. Essas iniciativas contam com pouco respaldo técnico normativo, diretrizes ou legislação que orientem projetistas, executores e gestores sobre as práticas adequadas de implantação, operação e manutenção desses sistemas, o que pode colocar em risco a saúde dos usuários e o sucesso dessa tecnologia. Considerando-se que é indispensável atender às necessidades dos usuários por meio da adequação das soluções ao uso, a Avaliação Durante Operação (ADO apresenta-se como uma ferramenta adequada para a análise da situação atual do sistema. Nesse contexto, este artigo tem como objetivo avaliar o desempenho de sistemas prediais de água não potável durante sua operação em edifícios residenciais no que se refere a projeto, execução, operação e manutenção. Para tanto foi aplicada a metodologia de ADO em seis edifícios residenciais. Os resultados mostram que a falta de capacitação técnica, de normas técnicas e de legislações específicas que orientem projetistas, executores, gestores e usuários contribui para o atual cenário, caracterizado por sistemas que operam com desempenho inferior para atender às necessidades e garantir a segurança dos usuários.

    Full Text Available The “Opera del Duomo” is the institution, still in existence, which was responsible for the construction of the cathedral in Orvieto. Over the centuries there have been many changes to its structure, in part due to continual conflict between the public administration and religious organizations. In accordance with the interpretation of the development of accounting as a result of its historical context, and, in particular, its organizational structure, this paper aims, through an analysis of the accounting registers and books of the Opera, to investigate “if” and “when” it is possible to observe the introduction of the double-entry bookkeeping method, and its role and function in the Opera’s structure.

  2. 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...

  3. Efficacy of Cool-Down Exercises In the Practice Regimen of Elite Singers

    Science.gov (United States)

    Gottliebson, Renee O.

    Cool-down exercises are routinely prescribed for singers, yet few data exist about the efficacy of active recovery or cooling down of the vocal mechanism. The purpose of the present study was to compare three aspects of vocal function after using different recovery methods following rigorous voice use. Vocal function was assessed using (1) phonation threshold pressure (PTP); (2) acoustic measures (accuracy of tone production, duration of notes and duration of intervals between notes); and (3) measures of subjective perception: perceived phonatory effort (PPE) and Singing Voice Handicap Index (SVHI). Data were collected after 10-minutes of cool-down exercises, complete voice rest, and conversation immediately following a 50-minute voice lesson. Data were collected again 12-24 hours later. Participants included actively performing elite singers (7 women, 2 men) enrolled in the graduate program (M.M., D.M.A.) at the University of Cincinnati's College-Conservatory of Music. While it was expected that PTP estimates after cool downs would be significantly lower than baselines and the other conditions, it turns out that PTP estimates after cool downs were significantly higher at the 80% level of the pitch range. Statistically significant correlations between PTP estimates and PPE scores were found when comparing levels of the participants' pitch ranges (10%, 20%, 80%). Mean PPE scores were highest at the 80% level of the pitch range. The acoustic measures yielded variable results. Cool-down exercises did not result in significantly more accurate tone production and shorter staccato note duration and duration of intervals between staccato notes as compared to baselines and recovery conditions. Instead, participants demonstrated greater accuracy of tone production during baselines and lesser accuracy after voice rest. Staccato notes were significantly shorter in duration after the conversation condition as compared to voice rest. Duration between staccato notes was

    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.

  6. 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...

    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.

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

    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.

    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.......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...

  11. The Ghost-Image on Metropolitan Borders—In Terms of Phantom of the Opera and 19th-Century Metropolis Paris

    Directory of Open Access Journals (Sweden)

    Changnam Lee

    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.

  12. Measurement of the cosmic ray muon charge ratio with the OPERA detector

    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.

  13. Singing proficiency in the majority: normality and "phenotypes" of poor singing.

    Recent evidence indicates that the majority of occasional singers can carry a tune. For example, when asked to sing a well-known song (e.g., "Happy Birthday"), nonmusicians performing at a slow tempo are as proficient as professional singers. Yet, some occasional singers are poor singers, mostly in the pitch domain, and sometimes despite not having impoverished perception. Poor singing is not a monolithic deficit, but is likely to be characterized by a diversity of singing "phenotypes." Here we systematically examined singing proficiency in a group of occasional singers, with the goal of characterizing the different patterns of poor singing. Participants sang three well-known melodies (e.g., "Jingle Bells") at a natural tempo and at a slow tempo, as indicated by a metronome. For each rendition, we computed objective measures of pitch and time accuracy with an acoustical method. The results confirmed previous observations that the majority of occasional singers can sing in tune and in time. Moreover, singing at a slow tempo after the target melody to be imitated was presented with a metronome improved pitch and time accuracy. In general, poor singers were mostly impaired on the pitch dimension, although various patterns of impairment emerged. Pitch accuracy or time accuracy could be selectively impaired; moreover, absolute measures of singing proficiency (pitch or tempo transposition) dissociated from relative measures of proficiency (pitch intervals, relative duration). These patterns of dissociations point to a multicomponent system underlying proficient singing that fractionates as a result of a developmental anomaly.

    The OPERA detector at the Gran Sasso underground laboratory (LNGS) was used to measure the atmospheric muon charge ratio R μ =N μ + /N μ - in the TeV energy region. We analyzed 403069 atmospheric muons corresponding to 113.4 days of lifetime 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 R μ dependence on the primary composition. The measured R μ values were corrected taking into account the charge-misidentification errors. Data have also been grouped in five bins of the ''vertical surface energy'' E μ cos θ. 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. (orig.)

  15. 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

  20. 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.

  1. Theory of acoustic design of opera house and a design proposal

    Ando, Yoichi

    2004-05-01

    First of all, the theory of subjective preference for sound fields based on the model of auditory-brain system is briefly mentioned. It consists of the temporal factors and spatial factors associated with the left and right cerebral hemispheres, respectively. The temporal criteria are the initial time delay gap between the direct sound and the first Reflection (Dt1) and the subsequent reverberation time (Tsub). These preferred conditions are related to the minimum value of effective duration of the running autocorrelation function of source signals (te)min. The spatial criteria are binaural listening level (LL) and the IACC, which may be extracted from the interaural crosscorrelation function. In the opera house, there are two different kind of sound sources, i.e., the vocal source of relatively short values of (te)min in the stage and the orchestra music of long values of (te)min in the pit. For these sources, a proposal is made here.

    The production and perception of music is preferentially mediated by cortical areas within the right hemisphere, but little is known about how these brain regions individually contribute to this process. In an experienced singer undergoing awake craniotomy, we demonstrated that direct electrical stimulation to a portion of the right posterior superior temporal gyrus (pSTG) selectively interrupted singing but not speaking. We then focally cooled this region to modulate its activity during vocalization. In contrast to similar manipulations in left hemisphere speech production regions, pSTG cooling did not elicit any changes in vocal timing or quality. However, this manipulation led to an increase in the pitch of speaking with no such change in singing. Further analysis revealed that all vocalizations exhibited a cooling-induced increase in the frequency of the first formant, raising the possibility that potential pitch offsets may have been actively avoided during singing. Our results suggest that the right pSTG plays a key role in vocal sensorimotor processing whose impact is dependent on the type of vocalization produced. Copyright © 2017 Elsevier Ltd.

    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 most obvious national features are to be found in the subject of the opera based on the famous English medieval epic poem Sir Gawain and the Green Knight. They are also displayed in the references to Shakespeare, to other British composers (Michael Tippett and Henry Purcell for instance and to typical English musical or musico-dramatic forms such as the masque. As far as the foreign borrowings or influences are concerned, Harrison Birtwistle’s debt to composers like Richard Wagner, Igor Stravinsky and Olivier Messiaen is once more displayed in Gawain. Other influences are shown through his translation into music of aesthetic ideas inspired by the great German painter Paul Klee and through his adaptation of elements taken from Greek tragedy. One can thus wonder if this fusion or juxtaposition of vernacular and foreign elements is not one of the key features of Gawain.

    Full Text Available La opera flotante de John Barth tiene varias puertas de acceso para el análisis. Una de ellas nos lleva a indagar sobre el tema que circunda la obra: el suicidio. Para ello, en el presente trabajo vamos a contrastar las posibles características apocalípticas del personaje principal, Todd Andrews, con determinados postulados de la filosofía existencialista de Jean Paul Sartre. La propuesta estará centrada en revisar puntos de divergencia y de afinidad en ambas cosmovisiones.

    Most voice self-rating tools are disease-specific measures and are not suitable for use with healthy voice users. There is a need for a tool that is sensitive to the subtleties of a singer's voice and to perceived physical changes in the singing voice mechanism as a function of load. The aim of this study was to devise and validate a scale to assess singer's perceptions of the current status of their singing voice. Ninety-five vocal health descriptors were collected from focus group interviews of singers. These were reviewed by 25 currently performing music theater (MT) singers. Based on a consensus technique, the number of descriptors was decreased to 42 items. These were administered to a sample of 284 professional MT singers using an online survey to evaluate their perception of current singing voice status. Principal component analysis identified two subsets of items. Rasch analysis was used to evaluate and refine these sets of items to form two 10-item subscales. Both subscales demonstrated good overall fit to the Rasch model, no differential item functioning by sex or age, and good internal consistency reliability. The two subscales were strongly correlated and subsequent Rasch analysis supported their combination to form a single 20-item scale with good psychometric properties. The Evaluation of the Ability to Sing Easily (EASE) is a concise clinical tool to assess singer's perceptions of the current status of their singing voice with good measurement properties. EASE may prove a useful tool to measure changes in the singing voice as indicators of the effect of vocal load. Furthermore, it may offer a valuable means for the prediction or screening of singers "at risk" of developing voice disorders. Copyright © 2013 The Voice Foundation. All rights reserved.

  13. Of Lady-killers and ‘Men Dressed As Women’: Soap Opera, Scapegoats and the Mexico City Police Department

    Directory of Open Access Journals (Sweden)

    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.

    Matthias Echternach

    Full Text Available Due to a lack of empirical data, the current understanding of the laryngeal mechanics in the passaggio regions (i.e., the fundamental frequency ranges where vocal registration events usually occur of the female singing voice is still limited.In this study the first and second passaggio regions of 10 professionally trained female classical soprano singers were analyzed. The sopranos performed pitch glides from A3 (ƒo = 220 Hz to A4 (ƒo = 440 Hz and from A4 (ƒo = 440 Hz to A5 (ƒo = 880 Hz on the vowel [iː]. Vocal fold vibration was assessed with trans-nasal high speed videoendoscopy at 20,000 fps, complemented by simultaneous electroglottographic (EGG and acoustic recordings. Register breaks were perceptually rated by 12 voice experts. Voice stability was documented with the EGG-based sample entropy. Glottal opening and closing patterns during the passaggi were analyzed, supplemented with open quotient data extracted from the glottal area waveform.In both the first and the second passaggio, variations of vocal fold vibration patterns were found. Four distinct patterns emerged: smooth transitions with either increasing or decreasing durations of glottal closure, abrupt register transitions, and intermediate loss of vocal fold contact. Audible register transitions (in both the first and second passaggi generally coincided with higher sample entropy values and higher open quotient variance through the respective passaggi.Noteworthy vocal fold oscillatory registration events occur in both the first and the second passaggio even in professional sopranos. The respective transitions are hypothesized to be caused by either (a a change of laryngeal biomechanical properties; or by (b vocal tract resonance effects, constituting level 2 source-filter interactions.

  17. From Opera to Real Democracy: Popular Constitutionalism and Web 2.0

    2013-01-01

    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.

    Love, Sex, and Choices (LSC) is a soap opera video series created to reduce HIV sex risk in women. LSC was compared to text messages in a randomized trial in 238 high-risk mostly Black young urban women. 117 received 12-weekly LSC videos, 121 received 12-weekly HIV prevention messages on smartphones. Changes in unprotected sex with high risk partners were compared by mixed models. Unprotected sex with high risk men significantly declined over 6 months post-intervention for both arms, from 21-22 acts to 5-6 (p video over the text arm, though this difference was not statistically significant. However, the LSC was highly popular and viewers wanted the series to continue. This is the first study to report streaming soap opera video episodes to reduce HIV risk on smartphones. LSC holds promise as an Internet intervention that could be scaled-up and combined with HIV testing. Copyright © 2013 Elsevier Inc. All rights reserved.

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

    Hyunsun Catherine Yoon

    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.

    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.

    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

    2013-05-01

    This study was designed as a qualitative case study to demonstrate the process of diagnosis and treatment between a voice team to manage a singer diagnosed with muscular tension dysphonia (MTD). Traditionally, literature suggests that MTD is challenging to treat and little in the literature directly addresses singers with MTD. Data collected included initial medical screening with laryngologist, referral to speech-language pathologist (SLP) specializing in voice disorders among singers, and adjunctive voice training with voice teacher trained in vocology (singing voice specialist or SVS). Initial target goals with SLP included reducing extrinsic laryngeal tension, using a relaxed laryngeal posture, and effective abdominal-diaphragmatic support for all phonation events. Balance of respiratory forces, laryngeal coordination, and use of optimum filtering of the source signal through resonance and articulatory awareness was emphasized. Further work with SVS included three main goals including a lowered breathing pattern to aid in decreasing subglottic air pressure, vertical laryngeal position to lower to allow for a relaxed laryngeal position, and a top-down singing approach to encourage an easier, more balanced registration, and better resonance. Initial results also emphasize the retraining of subject toward a sensory rather than auditory mode of monitoring. Other areas of consideration include singers' training and vocal use, the psychological effects of MTD, the personalities potentially associated with it, and its relationship with stress. Finally, the results emphasize that a positive rapport with the subject and collaboration between all professionals involved in a singer's care are essential for recovery.

Methods: An observational and documental study for which were selected sound sources presenting musical genres and styles that are part of the experience of the researchers, which were analyzed considering origins, formative elements and vocal features. Alongside we carried out a review of literature grounded in databases research and free review of websites and classical books of the area. Results: The selected styles (Rock and Roll, Heavy Metal, Trash Metal, Grunge, Gothic Metal, Rap, Funk, Blues, R&B – Rhythm and Blues, Soul, Gospel, MPB, Samba, Forro, Sertanejo, Bossa Nova, Opera and Chamber Music were described, pointing the reasons for the speech therapist to be informed about them and about singing voice aspects. His guidance may minimize possible vocal damage caused by each style, since each of them carries its own patterns to which the interpreter must submit. Conclusions: We conclude that the singer will use a specific vocal pattern that resembles the musical style he intends to sing, regardless of any harm it may or may not cause to vocal health. When choosing a musical style, it is important that the singer has the knowledge and understanding of how the use of his vocal apparatus will cause or not cause injury to his voice. Also be aware that the technique in singing is necessary for vocal longevity.

    2000-04-01

    The interactive multi-channel computer music system known as the Virtual Orchestra has been used several times in professional opera and theater as an alternative to a live pit orchestra. The technical issues associated with this emerging technology, and the logistical problems of implementing it are discussed. In addition, this paper describes the equally important issues regarding the creative impact this will have on the industry. In particular, this paper explores the role of the musician/technologist and suggests that many of the fundamental premises of opera production will change as the industry begins to retool. This would include the way opera is rehearsed and performed, how it is created and disseminated, and how it will adjust to changing demographics.

    Full Text Available One of the limitations for reaching sustainable forest development is related to the traffic of machines and vehicles during harvest operations and wood transport, which may cause soil structure degradation. Seeking a way to analyze this problem, the objective of this study was to determine the traffic effects due to harvest operations and wood transport, on the preconsolidation pressure (sigmap in a Typic Acrustox cultivated with eucalyptus. This study was conducted using undisturbed soil samples collected at the 0.1-0.125 m depth. Undisturbed soil samples were used in the uniaxial compression tests. Soil sampling consisted of two stages, before and after the mechanized harvest operations. The traffic effects on the sigmap in the dry season indicated that the soil compaction process was neither evident nor important. However, in the rainy season the traffic effects on the sigmap indicated that the operations performed with Harvester and Forwarder caused greater soil compaction than those with Motorized Saw and Manual, which caused less soil compaction.Uma das limitações para alcançar o desenvolvimento florestal sustentável está relacionado ao tráfico de máquinas e veículos durante as operações de colheita e transporte de madeira que podem causar degradação da estrutura do solo.

    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.

    2009-11-01

    Full Text Available The many images of bonds and confinement in The Beggar’s Opera are metaphorical prefigurations of death by hanging, which threatens every character in the play. The only way in which they can delay this inevitable outcome is by keeping bodies, money and meaning in movement, while fixity means immediate death. Female desire, however, is phobically represented as mortiferous desire, whose ultimate goal is to reintroduce bonds and knots—especially "the sacred knots of marriage." The two ends offer two opposite outcomes for the war between the sexes which structures the plot: while the female taste for fixity triumphs in the original "tragic" end, the male propension for play has the final word in the Player’s comic version.

    Because vocal technique is the basis of singing a song beautifully, so this study was undertaken to use the scientific and correct technique in order to get much better musical expressions. Shimadzu X-ray remote control TV system was used for checking the supporting state of diaphragmatic respiration after 5, 10, 15, 20, 25 and 30 sec during phonation in the state of full inhalation between professional singer and non-professional singer. Shimadzu Magnet nex-α(SMT-50CX/H) was used for examining the scattering state from the resonance of nasal caity to that of cranial cavity on the basis of diaphragmatic respiration. The results obtained were summerized as follows: 1. The resonance of cranial cavity must be scattered by the energy of diaphragmatic respiration after gathering the foci of the fundamental 5 vowels. 2. While raising the epiglottis, the resonance of nasal cavity must be clearly in order to maintain the resonance of cranial cavity beautifully. 3. We can get musical expressions by maintaining the elasticity of diaphragmatic respiration.=20

    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.)

  4. The enter-educate approach.

    This article describes how the Population Communication Services (PCS) has seized on the "enter-educate" approach, the blending of popular entertainment with social messages, to change reproductive health behavior. The enter-educate approach spreads its message through songs, soap operas, variety shows, and other types of popular entertainment mediums. Because they entertain, enter-educate projects can capture the attention of an audience -- such as young people -- who would otherwise scorn social messages. And the use of population mediums makes it possible to reach a variety of audiences. Funded by USAID, PCS began its first enter-educate project in response to the increasing number of teenage pregnancies in Latin America. PCS developed 2 songs and videos, which featured popular teenage singers to serve as role models, to urge abstinence. The songs became instant hits. Since then, PCS has mounted more then 80 major projects in some 40 countries. Highlights of programs range from a successful multi-media family planning campaign in Turkey to humorous television ads in Brazil promoting vasectomy. Recently, PCS initiated projects to teach AIDS awareness. At the core of the enter-educate approach is the social learning theory which holds that much behavior is learned through the observation of role-models. Health professionals work alongside entertainers to produce works that have audience appeal and factual social messages. The enter-educate approach works because it is popular, pervasive, personal, persuasive, and profitable. PCS has found that enter-educate programs pay for themselves through cost sharing and cost recovery.

    2018-03-01

    The present study aimed to observe whether physiological warm-up and traditional singing warm-up differently affect aerodynamic, electroglottographic, acoustic, and self-perceived parameters of voice in Contemporary Commercial Music singers. Thirty subjects were asked to perform a 15-minute session of vocal warm-up. They were randomly assigned to one of two types of vocal warm-up: physiological (based on semi-occluded exercises) or traditional (singing warm-up based on open vowel [a:]). Aerodynamic, electroglottographic, acoustic, and self-perceived voice quality assessments were carried out before (pre) and after (post) warm-up. No significant differences were found when comparing both types of vocal warm-up methods, either in subjective or in objective measures. Furthermore, the main positive effect observed in both groups when comparing pre and post conditions was a better self-reported quality of voice. Additionally, significant differences were observed for sound pressure level (decrease), glottal airflow (increase), and aerodynamic efficiency (decrease) in the traditional warm-up group. Both traditional and physiological warm-ups produce favorable voice sensations. Moreover, there are no evident differences in aerodynamic and electroglottographic variables when comparing both types of vocal warm-ups. Some changes after traditional warm-up (decreased intensity, increased airflow, and decreased aerodynamic efficiency) could imply an early stage of vocal fatigue.

    The aim of the study was to determine the prevalence of orthorexia nervosa among the performance artists in the State Opera and Ballet and in the Bilkent University Symphony Orchestra. The study population consisted of 39 men and 55 women for a total of 94 artists with mean age of 33 years. The ORTO-15 test was used to determine the prevalence of orthorexia nervosa. Those subjects who scored below 40 in the ORTO-15 test were classified as having orthorexia nervosa. Mean score of the participants in the ORTO-15 test was 37.9+/-4.46. A total of 56.4% of the artists involved in the research scored below 40 in the ORTO-15 test. While the highest prevalence of orthorexia nervosa was recorded among opera singers (81.8%), it was 32.1% among ballet dancers and 36.4% among symphony orchestra musicians. The differences between the three groups were statistically significant. No difference was noted between mean ORTO-15 score by baseline characteristics as gender, age, educational level, work experience, body mass index, smoking and alcohol consumption. The research group have a higher socio-economic and education level than the majority of the general public in Turkey. Additionally, being an artist in Turkey means being a role model for the general public both in terms one's physical appearance and lifestyle. These may be the reason why artists are more sensitive to this issue.

  9. 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.

    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)

However, studies of speech phonation have shown that gravity can affect vocal tract shape and bias measurements. This is one of the reasons that MRI studies of singing phonation have used professionally trained singers as subjects, because they are generally considered to be less affected by the supine body position and environmental distractions. A study of untrained singers might not only contribute to the understanding of intuitive singing function and aid the evaluation of potential hazards for vocal health, but also provide insights into the effect of the supine position on singers in general. In the present study, an open configuration 0.25 T MRI system with a rotatable examination bed was used to study the effect of body position in 20 vocally untrained subjects. The subjects were asked to sing sustained tones in both supine and upright body positions on different pitches and in different register conditions. Morphometric measurements were taken from the acquired images of a sagittal slice depicting the vocal tract. The analysis concerning the vocal tract configuration in the two body positions revealed differences in 5 out of 10 measured articulatory parameters. In the upright position the jaw was less protruded, the uvula was elongated, the larynx more tilted and the tongue was positioned more to the front of the mouth than in the supine position. The findings presented are in agreement with several studies on gravitational effects in speech phonation, but contrast with the results of a previous study on professional singers of our group where only minor differences between upright and supine body posture were observed. The present study demonstrates that imaging of the vocal tract using weight-bearing MR imaging is a feasible tool for the study of sustained phonation in singing for vocally untrained subjects.

    Full Text Available A palhada de cobertura residual representa o grande diferencial do sistema de semeadura direta, propiciando melhorias nas condições biológicas, químicas e físicas do solo, em contrapartida esta matéria seca residual pode implicar em dificuldades no processo de semeadura, necessitando por vezes de um manejo deste resíduo. O presente trabalho teve por objetivo avaliar o desenvolvimento e produtividade da cultura do milho submetido a diferentes métodos de manejo de palhada, mecanismos sulcadores e velocidades de operação. Utilizou-se o delineamento em blocos ao acaso com parcelas subsubdivididas, composto por 16 tratamentos e quatro repetições, totalizando 64 unidades experimentais. Os tratamentos foram compostos pela combinação entre quatro manejos de palhada (palha gradeada, rolada, triturada e dessecada, dois mecanismos sulcadores (disco duplo e haste sulcadora e duas velocidades de semeadura (4,5 e 7,0 km h-1. Avaliou-se a profundidade de deposição de sementes, área de solo mobilizada, uniformidade de distribuição de sementes, estande inicial de plantas, número de fileiras por espiga, número de grãos por fileira, massa de mil grãos e produtividade da cultura. Os dados obtidos foram submetidos às análises de variância e havendo diferenças significativas, as médias foram comparadas pelo teste de Tukey, a 5% de significância. A velocidade de operação de 7,0 km h-1 apresentou valores de espaçamentos falhos e duplos mais elevados. Os tratamentos empregados não influenciaram os componentes de rendimento da cultura, bem como não se observou diferenças significativas para a produtividade média da cultura de milho.

    Full Text Available 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 establish whether exercise is effective in reducing the prevalence of depression among older RNH residents. Method OPERA is a cluster randomised controlled trial. RNHs are randomised to one of two groups with interventions lasting 12 months Intervention group: a depression awareness and physical activity training session for care home staff, plus a whole home physical activation programme including twice weekly physiotherapist-led exercise groups. The intervention lasts for one year from randomisation, or Control group: a depression awareness training session for care home staff. Participants are people aged 65 or over who are free of severe cognitive impairment and willing to participate in the study. Our primary outcome is the prevalence of depressive symptoms, a GDS-15 score of five or more, in all participants at the end of the one year intervention period. Our secondary depression outcomes include remission of depressive symptoms and change in GDS-15 scores in those with depressive symptoms prior to randomisation. Other secondary outcomes include, fear of falling, mobility, fractures, pain, cognition, costs and health related quality of life. We aimed to randomise 77 RNHs. Discussion Home recruitment was completed in May 2010; 78 homes have been randomised. Follow up will finish in May 2011 and results will be available late 2011.

    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.

    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

    Voice is one of the most important instruments for expression and communication in humans. Dysphonia remains very frequent. Generally people in voice-intensive professions, such as teachers, call center employees, singers and actors suffer from these complaints. In recent years methods have been developed which facilitate appropriate diagnosis and therapy, based on the criteria of evidence based medicine, in voice patients appropriate to their degree of disease. The basic protocol of the European Laryngological Society offers a standardized evaluation of multidimensional voice parameters. In our own patient collective there were statistically significant improvements in voice quality, according to a pre/post mean value comparison, in both phonomicrosurgical (n=45) and voice therapy (n=30) patients in relation to RBH, DSI and VHI.

    The OPERA spectrometer is built from two large dipoles instrumented with around 1000 Resistive Plate Chambers (RPCs), covering a surface of about 3350 m 2 , and digitally read out by means of almost 27000 strips. 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.

    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

    Accurate tuning is an important aspect of singing in harmony in the context of a choir or vocal ensemble. Tuning and 'pitch drift' are concerning factors in performance for even the most accomplished professional choirs when singing a cappella (unaccompanied). In less experienced choirs tuning often lacks precision, typically because individual singers have not developed appropriate listening skills. In order to investigate accuracy of tuning in ensemble singing situations, a chorally appropriate reference is required against which frequency measurements can be made. Since most basic choral singing involves chords in four parts, a four-part reference template is used in which the fundamental frequencies of the notes in each chord can be accurately set. This template can now be used in experiments where three of the reference parts are tuned in any musical temperament (tuning system), in this case equal and just temperaments, and played over headphones to a singer to allow her/his tuning strategy to be investigated. This paper describes a practical implementation of a four-part choral synthesis system in Pure Data (Pd) and its use in an investigation of tuning of notes by individual singers using an exercise originally written to explore pitch drift in a cappella choral singing.

    2016-10-01

    To identify the relationship between professionalism and professional quality of life among oncology nurses working at tertiary hospitals in Korea. Oncology nurses are combined with core competencies and qualities required in cancer patient care. Professionalism that means compassion satisfaction and compassion fatigue is a main concept in problem-solving strategies as motivation. Their satisfaction is representative of professionalism and professional quality of life. However, little research has focused on professionalism and professional quality of life. A cross-sectional study with self-administered questionnaires. A total of 285 nurses from two tertiary hospitals were included. Data collection was undertaken using Korean version of professionalism scale derived from the Hall Professional Inventory Scale and professional quality of life. Data were analysed by spss 21.0 for Windows Program using t-test, anova, and multiple regression. The mean score of professionalism in oncology nurses was 77·98 ± 7·31. The mean professional quality of life score for compassion satisfaction, compassion fatigue and secondary traumatic stress was 33·84 ± 5·62, 28·38 ± 5·36 and 28·33 ± 5·48. Compassion satisfaction was affected by factors of professionalism with an explanatory power of 49·2%. Burnout and secondary traumatic stress were affected by factors of professionalism with an explanatory power of 39·3% and 4·8%. The higher the professionalism leads to the higher the compassion satisfaction, the lower the compassion fatigue. The relationship between professionalism and professional quality of life for a health work environment requires further investigation. Our study supports the idea that enhancing professionalism can increase professional quality of life. It is necessary to develop professionalism by recognised qualifications and applied rewards in advanced nursing organisational culture. Furthermore, compassion satisfaction is increased by

    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

    Objective It is generally believed that professional drivers can manage quite severe fatigue before routine driving performance is affected. In addition, there are results indicating that professional drivers can adapt to prolonged night shifts and may be able to learn to drive without decreased performance under high levels of sleepiness. However, very little research has been conducted to compare professionals and non-professionals when controlling for time driven and time of day. Method The aim of this study was to use a driving simulator to investigate whether professional drivers are more resistant to sleep deprivation than non-professional drivers. Differences in the development of sleepiness (self-reported, physiological and behavioral) during driving was investigated in 11 young professional and 15 non-professional drivers. Results Professional drivers self-reported significantly lower sleepiness while driving a simulator than non-professional drivers. In contradiction, they showed longer blink durations and more line crossings, both of which are indicators of sleepiness. They also drove faster. The reason for the discrepancy in the relation between the different sleepiness indicators for the two groups could be due to more experience to sleepiness among the professional drivers or possibly to the faster speed, which might unconsciously have been used by the professionals to try to counteract sleepiness. Conclusion Professional drivers self-reported significantly lower sleepiness while driving a simulator than non-professional drivers. However, they showed longer blink durations and more line crossings, both of which are indicators of sleepiness, and they drove faster.

    Singing is universal, and understanding sung words is thought to be important for many listeners' enjoyment of vocal and choral music. However, this is not a trivial task, and sung text intelligibility is probably affected by many factors. A survey of musicians was undertaken to identify the factors believed to have most impact on intelligibility, and to assess the importance of understanding sung words in familiar and unfamiliar languages. A total of 143 professional and amateur musicians, including singers, singing teachers, and regular listeners to vocal music, provided 394 statements yielding 851 references to one or more of 43 discrete factors in four categories: performer-related, listener-related, environment-related and words/music-related. The factors mentioned most frequently in each of the four categories were, respectively: diction; hearing ability; acoustic; and genre. In more than a third of references, the extent to which sung text is intelligible was attributed to the performer. Over 60% of respondents rated the ability to understand words in familiar languages as "very important," but only 17% when the text was in an unfamiliar language. Professional musicians (47% of the sample) rated the importance of understanding in both familiar and unfamiliar languages significantly higher than amateurs but listed fewer factors overall and fewer listener-related factors. The more important the respondents rated understanding, the more performer-related and environment-related factors they tended to list. There were no significant differences between the responses of those who teach singing and those who do not. Enhancing sung text intelligibility is thus perceived to be within the singer's control, at least to some extent, but there are also many factors outside their control. Empirical research is needed to explore some of these factors in greater depth, and has the potential to inform pedagogy for singers, composers, and choral directors.

    This mixed-methods exploratory study investigates the perceived health benefits of singing in a choir from an international sample of choristers. An online questionnaire including demographic information, 28 quantitative statements and two qualitative questions relating to the perceived health benefits of singing in a choir was distributed via email and social media over a period of 4 months to a sample of 1,779 choristers. Basic descriptives and comparisons between subgroups of the sample are presented along with thematic analysis of qualitative comments. Basic descriptives suggest an overwhelmingly positive response. Females scored significantly higher than males on physical benefits, social benefits and emotional benefits. Professional singers reported significantly more physical, social and spiritual benefits than amateur singers. Bias may be present in these findings as the results were entirely self-reported by people who already sing in choirs. Qualitative thematic analysis identified six key themes which may counter this bias by providing deeper understanding of the perceived benefits for choir singers. These include social connection, physical and physiological benefits (specifically respiratory health), cognitive stimulation, mental health, enjoyment and transcendence. Choral singing elicits a positive response in the chorister across a plethora of domains. This research confirms previous findings on the health benefits of singing but offers evidence from the largest sample of singers to date. However, results are based on self-perceptions of choristers, and findings are, therefore, limited. Results may be used as a base on which to develop further research in this area. It also provides confirmatory evidence to support choral singing as a means of improving wellbeing in many populations, including but not limited to workplaces, schools, nursing homes, communities and churches.

    Full Text Available With the emergence of research on real-time visual feedback to supplement vocal pedagogy, the utilization of technology in the world of music is now seen to accelerate skills learning and enhance cognitive development. The researchers of this project aim to further analyze vowel intelligibility and develop software applications intended to be used not only by professional singers but also by individuals who wish to improve their singing capability. Data in the form of sung vowels and song pieces were obtained from 46 singers. A Listening Test was then conducted on these samples to obtain the ground truth for vowel classification based on human perception. Simulation of the human auditory perception of sung Filipino vowels was performed using formant frequencies and Mel-frequency cepstral coefficients as feature vector inputs to a two-stage Discriminant Analysis classifier. The setup resulted in an over-all Training Set accuracy of 89.4% and an over-all Test Set accuracy of 90.9%. The accuracy of the classifier, measured in terms of the correspondence of vowel classifications obtained from the classifier with the results of the Listening Test, reached 92.3%. Using information obtained from the classifier, offline and online/real-time software applications were developed. The main application features include the display of the spectral envelope and spectrogram, pitch and vibrato analysis and direct feedback on the classification of the sung vowel. These features were recommended by singers who were surveyed and were incorporated in the applications to aid singers to adjust formant locations, directly determine listener’s perception of sung vowels, perform modeling effectively and carry out vowel migration.

    Full Text Available This paper examines the representation of vocal virtuosity in fiction. It focuses on the concept of voice as it is represented in a work of fiction through musical eccentricity. The paper centres on James McCourt’s Mawrdew Czgowchwz (1975. James McCourt’s novel tells the story of an opera singer, Mawrdew Czgowchwz. In the novel, the voice is related to extravagance and fanaticism, so that it relates to violence and conflict. In McCourt’s novel, the stylistic features of the text show a hyperbolic use of language resorting to Rabelaisian lists, foreign vocabulary, neologisms, or nonce-words, which create tongue-twister cornucopia effects of linguistic musicality. The paper aims to demonstrate that (a the mode of eccentricity is a fundamental mode of representing music in literature; (b eccentricity rubs off on the very structure of the text, so that it leads to singular forms of operatic musicalization of fiction and musicalized writing; (c the voice ends up turning into a fetish object.

    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 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 The article reviews teachers' attitudes towards the teaching profession which can be expressed both in professional commitment and in professional marginalism. The dominance of professional marginalism could affect destructively the students as well as the teacher’s personality, hence the issues related to the content of personal position of a marginal and the rate of marginalism among teachers. It was suggested that marginalism could be revealed in the study of professional commitment. The study involved 81 teachers of Sverdlovsk secondary schools aged 21—60 years with work experience ranging from 1 month to 39 years. The Professional Commitment Questionnaire was used as the study technique. The results showed that negative emotional attitude towards the profession and reluctance to leave the profession were grouped as a separate factor. The dispersion factor was 12,5%. The factor loadings ranged from 0.42 to 0.84. The study proved that professional marginalism in teachers includes dissatisfaction with work, feelings of resentment against profession and an unwillingness to leave the profession.

    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

    Professional behaviors are an integral part of clinical practice in all allied health and medical fields. A systematic process for instruction, the education, and development of professional behaviors, cannot be taught in the same way that memorization of human anatomy or medical terminology is taught. One cannot expect professional behaviors to just appear in an individual upon graduation and entry into a health care field. Professional behavior development is an essential component of physical therapy professional education and is clearly defined through the guiding documents of the American Physical Therapy Association, which include 'A Normative Model of Physical Therapist Professional Education,' 'Evaluative Criteria for Accreditation of Education Programs for the Preparation of Physical Therapists,' and the 'Guide to Physical Therapist Practice.' Building a comprehensive and progressive curricular thread for professional behaviors can pose a challenge for a professional program and the core faculty. This paper will present a curricular model of weaving professional behaviors into a core entry-level professional curriculum using a specific curricular thread, activities for different levels of students, and assessment at each point in the path. This paper will demonstrate the potential for universal application of a professional behaviors.

    Full Text Available While other American plays such as Elmer Rice’s Street Scene, Tennessee Williams’ A Streetcar Named Desire, and Eugene O’Neill’s Mourning Becomes Electra have made the journey from stage to film and finally to opera, the film and operatic versions were faithful recreations of the original without the addition of new characters, including those from other works by the same playwright.  Lillian Hellman’s best play, The Little Foxes (1939, is unusual in two respects: in the 1941 film version, a character is added who did not appear in the original in order to provide a love interest for the protagonist’s daughter, thereby resulting in a different ending;  in the 1949 operatic version, a character from a later play by Hellman, Another Part of the Forest, is introduced to show how a young woman with romantic ideals evolved into the Lady Macbeth of American drama. Thus each version of The Little Foxes deepens our understanding of the original without altering the play’s dramatic impact.

    Professionalism and professional skills are increasingly being incorporated into veterinary curricula; however, lack of clarity in defining veterinary professionalism presents a potential challenge for directing course outcomes that are of benefit to the veterinary professional. An online continuing education course in veterinary professionalism was designed to address a deficit in postgraduate support in this area; as part of this course, delegates of varying practice backgrounds participated in online discussions reflecting on the implications of professional skills for their clinical practice. The discussions surrounding the role of the veterinary professional and reflecting on strengths and weaknesses in professional skills were analysed using narrative methodology, which provided an understanding of the defining skills and attributes of the veterinary professional, from the perspectives of those involved (i.e. how vets understood their own career identity). The veterinary surgeon was understood to be an interprofessional team member, who makes clinical decisions in the face of competing stakeholder needs and works in a complex environment comprising multiple and diverse challenges (stress, high emotions, financial issues, work-life balance). It was identified that strategies for accepting fallibility, and those necessary for establishing reasonable expectations of professional behaviour and clinical ability, are poorly developed.

    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.

    In the changing medical environment, professional stress continuously increases as the individual's quality of life suffers. Of all the healthcare professions, nursing is especially prone to burnout, compassion fatigue and reduced compassion satisfaction, due to the tensions resulting from the physical and psychological stress of caring for extremely ill patients. This study examined the professional quality of life of clinical nurses in Korea and the relationship between their experiences in ethical dilemmas and professional values. This was a cross-sectional study of a convenience sample consisting of 488 clinical nurses. We used four questionnaires to measure the participants' demographic characteristics, experiences in ethical dilemmas, professional nursing values and professional quality of life (ProQOL assessment, Version 5). Ethical considerations: This study received approval from the Institutional Review Board of Bronco Memorial Hospital. Written informed consent was given by all participants. The nurses' professional quality of life was affected by ethical dilemmas and professional nursing values. The factors influencing compassion satisfaction were age, client domain of ethical dilemmas, social awareness, professionalism of nursing and the roles of nursing services in professional values. The factors influencing burnout were marital status (married), religion (yes), human life domain, professional work domain of ethical dilemmas, social awareness and the role of nursing services in nursing professional values. The factors influencing secondary traumatic stress were human life domain, client domain and the professional work domain of ethical dilemmas. Intervention to help nurses increase their professional quality of life will have a greater chance of success if they are based on the nurses' values and beliefs about the ethical dilemmas they face and foster the establishment of positive professional values. © The Author(s) 2014.

    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.

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.

    Since at least 1985, it seems that many of the articles and speeches directed to the contract management community have moved from a predominantly technical focus to one that is increasing philosophical. Philosophical in that the authors of such pieces attempt to define 'professionalism' and 'professional certification,' and, on occasion even attempt to loosely tie the traits and attributes of both to the achievement of 'excellence.' There is a profound but often misunderstood difference between the development of a professional worker and the establishment of professional qualification standards. In addition, the attainment of 'excellence' is not automatically the result of either. In this presentation these issues are addressed in the context of what contract managers should face and overcome

    Full Text Available Fundamentos: Próteses valvares aórticas com desempenho hemodinâmico adequado possibilitariam maior regressão da hipertrofia ventricular e normalização da função ventricular. Isto possivelmente tenha implicações importantes no prognóstico tardio após a substituição da valva aórtica. Objetivo: Avaliar o desempenho hemodinâmico do auto-enxerto pulmonar em posição aórtica e a regressão da hipertrofia ventricular esquerda após a operação de Ross. Casuística e Métodos: De maio/95 a março/97, 45 pacientes com média de idades de 27,1 anos foram submetidos à operação de Ross. Todos os pacientes foram submetidos, no pós-operatório imediato, a ecocardiografia com Doppler e cateterismo cardíaco para avaliação do desempenho hemodinâmico dos auto e homoenxertos, assim como da massa e função ventricular esquerda. Catorze pacientes com evolução superior a seis meses submeteram-se a ecocardiografia de stress com dobutamina, para estudar o desempenho hemodinâmico dos auto e homoenxertos em condição de exercício. Resultados: A mortalidade hospitalar foi de 6%. Após tempo médio de seguimento de 12,8 meses (1-23, ocorreu um óbito súbito tardio e nenhuma complicação relacionada à prótese. O desempenho hemodinâmico imediato e tardio dos auto-enxertos foi praticamente normal, com média de gradiente médio de 1,8 ± 0,6 mmHg e média de gradiente instantâneo máximo de 2,9 ± 0,9 mmHg. O grau de insuficiência valvar foi desprezível. Mesmo em condição de exercício, os gradientes não se elevaram de forma significativa, com média de gradiente médio de 4,3 ± 2,5 mmHg e média de gradiente instantâneo máximo de 10,4 ± 6,1 mmHg. Os homoenxertos utilizados para a reconstrução da via de saída do ventrículo direito tiveram excelente desempenho hemodinâmico imediato; entretanto, no seguimento tardio apresentaram discreto aumento das velocidades de fluxo com média de gradiente médio de 10 ± 7,1 mmHg em

    2015-11-01

    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.

  10. 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.

    Full Text Available The present essay aims at reviewing the issues and methodologies faced in my PhD research. The first step will be the analysis of the theoretical assumptions that underlie the emergence of ballet pantomime and the rediscovery of classical pantomime. The essay will proceed outlining the artistic and cultural landscapes of the two Italian cities examined, Milan and Naples, aiming at defining, from a didactic viewpoint, the teaching of pantomime in the two largest Italian academies, the Teatro alla Scala in Milan and the Teatro di San Carlo in Naples. The third step will be the recording of the few references to the mime art contained in the treaties and documents relating to the dance in Italy during the Nineteenth century (Carlo Blasis, Vincenzo Buonsignori, Giulio Pompeo Ferrario. These references will be compared to the major mime treatises for actors (Giovanni Emanuele Bideri, Antonio Morrocchesi, Angelo Canova, Alemanno Morelli and opera singers (Manuel Garcia, Fernando Pelzet, Leone Giraldoni, Enrico Serafino Torelli, Augusto Delle Sedie in order to analyze the development of gesture during the Nineteenth century and the different use that each interpreter did of the expressive mime.

    2017-01-01

    Full Text Available Professional socialisation of nursing students involves learning skills, attitudes, behaviour and professional roles, largely in the clinical area. During clinical accompaniment and reflective discussions with a group of undergraduate Baccalaureate nursing students in South Africa, students reported negative professional socialisation experiences, primarily in the clinical area. Such experiences could influence the quality of patient care. The objective of this study was to develop and validate guidelines to support professional nurses and educators in the professional socialisation of student nurses. Evidence was generated from an exploration and description of the perceptions of professional nurses regarding their role in the professional socialisation of students, the perceptions of nurse educators regarding the teaching and facilitation of professional socialisation of students, and the socialisation experiences of students. Following a sequential mixed-methods design, qualitative data guided the collection of quantitative data. All data and literature directed the development of these guidelines, which experts reviewed and validated according to a set of criteria. These guidelines focus on the clinical, nursing educational institution environment and values and beliefs of the nursing profession. Facilitation of sound work ethics, professional behaviour, cultural and gender awareness, role modelling and the application of a range of teaching strategies is proposed.

    The widespread use of digital media (both computing devices and the services they access) has blurred the boundaries between our personal and professional lives. Contemporary students are the last to remember a time before the widespread use of the Internet and they will be the first to practice in a largely e-health environment. This article explores concepts of digital professionalism and their place in contemporary medical education, and proposes a series of principles of digital professionalism to guide teaching, learning and practice in the healthcare professions. Despite the many risks and fears surrounding their use, digital media are not an intrinsic threat to medical professionalism. Professionals should maintain the capacity for deliberate, ethical, and accountable practice when using digital media. The authors describe a digital professionalism framework structured around concepts of proficiency, reputation, and responsibility. Digital professionalism can be integrated into medical education using strategies based on awareness, alignment, assessment, and accountability. These principles of digital professionalism provide a way for medical students and medical practitioners to embrace the positive aspects of digital media use while being mindful and deliberate in its use to avoid or minimize any negative consequences.

    Full Text Available In the present paper, we report the results of an empirical study on the effects of cognitive load on operatic singing. The main aim of the study was to investigate to what extent a working memory task affected the timing of operatic singers’ performance. Thereby, we focused on singers’ tendency to speed up, or slow down their performance of musical phrases and pauses. Twelve professional operatic singers were asked to perform an operatic aria three times; once without an additional working memory task, once with a concurrent working memory task (counting shapes on a computer screen, and once with a relatively more difficult working memory task (more shapes to be counted appearing one after another. The results show that, in general, singers speeded up their performance under heightened cognitive load. Interestingly, this effect was more pronounced in pauses – more in particular longer pauses – compared to musical phrases. We discuss the role of sensorimotor control and feedback processes in musical timing to explain these findings.
