Poética em caminhada: presença do corpo em voz nas letras das composições de Bob Dylan

This article investigates, in the lyrics of Bob Dylan's compositions, the record of a moving body in voice, driven by the background of the composer's biography. To this end, he begins by trying to understand the concept of the body in voice through Paul Zumthor's studies and whether there is a possibility of emerging from a lyric printed on paper, read as a poem, the lyrical repercussion of the singer. It also demonstrates from a phenomenological perspective in Bachelard that this body of voice, endowed with road experiences, can project paths in the imagination of the listener. To this end, the study selects five song lyrics from Dylan's work, recorded between 1962 and 1965, certifying thematic evidence and language mechanisms used by the composer, such as semantic travel topo vocabulary, analogies and metaphors, which can enable and prove a daydream of the walk in the receiver.Este artigo investiga, nas letras das composições de Bob Dylan, o registro de um corpo em voz que se movimenta, impulsionado pela bagagem da biografia do compositor. Para tanto, inicia tentando compreender o conceito do corpo em voz através dos estudos de Paul Zumthor e se há a possibilidade de emergir de uma letra impressa no papel, lida como um poema, a repercussão lírica do cancioneiro. Também demonstra, a partir de uma perspectiva fenomenológica em Bachelard, que esse corpo em voz, dotado de experiências de estrada, pode projetar caminhos na imaginação do leitor-ouvinte. Para isso o estudo seleciona cinco letras de canções da obra de Dylan, gravadas entre 1962 e 1965, certificando evidências temáticas e mecanismos de linguagem utilizados pelo compositor, como vocabulário semântico de topoi de viagem, analogias e metáforas, que podem possibilitar e comprovar um devaneio da caminhada no receptor. &nbsp

Narrativa autoficcial em A resistência: intersecções entre o real e o ficcional

O presente trabalho se vincula ao projeto Vozes da cultura contemporânea 2: o narrador na cultura da conexão, orientado pela Prof.ª Dr.ª Ana Cláudia Munari, o qual objetiva analisar a produção ficcional contemporânea a fim de encontrar tendências que se relacionem a novas práticas de leitura e escrita. Neste trabalho, nosso objeto é uma dessas tendências, a autoficção. A narrativa autoficcional pode ser observada em duas formas de ocorrência: quando os relatos de vivência do narrador se assemelham à biografia do autor empírico, ou nos trechos em que o narrador simula o processo de escrita (KLINGER, 2012). Para compreender essa presença autoficcional, o presente trabalho analisa A resistência (2015), de Julián Fuks. Na obra há, entre o autor e o narrador, uma aproximação íntima, uma mistura entre as experiências de um e a narrativa do outro. Ali, assistimos a um jogo performático no qual o narrador-protagonista assume estar escrevendo um livro, encenando seu processo de escritura para aquele que o lê. As revelações do próprio autor sobre a inserção de fatos reais no livro e a performance da escrita evidenciam uma conexão intrínseca entre a vida de Fuks e seu narrador. É nas confluências entre o real e o ficcional que focalizamos nossa análise

Micro-CT Evaluation of Gutta-Percha Removal by Two Retreatment Systems

Introduction: The aim of the present ex vivo research was to compare the remaining filling material and the volumes of dentine removed after retreatment of curved canals with two rotary systems naming ProTaper Universal Retreatment and Mani NRT-GPR using micro-computed tomography (micro-CT). Material and Methods: Forty mandibular molars containing two completely separated canals, with curvature angle of 25-35° and a curvature radius <10 mm were prepared to the Mtwo instrument 35/0.04 and filled with warm gutta-percha and AH-Plus sealer. The teeth were randomly divided into 2 groups (n=20), according to the retreatment system evaluated: ProTaper Universal Retreatment (PR group) or Mani NRT-GPR (MR group). Retreatment was considered complete when the working length was reached and when smooth dentinal walls were observed, with no evidence of filling material adhered to instruments or in the irrigating solution. Preoperative and postoperative micro-CT images were obtained with an isotropic voxel size of 11.88 µm to observe the volume of residual filling material in the canals and dentine removed after retreatment. Statistical analysis was performed by Student’s t-test (P<0.05). Results: The mean percentage of remaining filling material was 12.96% for PR group and 24.26% for MR group (P=0.0056). The percentage of dentin removal was greater in the PR group (5.02%) than MR group (1.36%) (P=0.0028). Both systems failed to completely remove the filling material from the canals. Conclusion: ProTaper Universal Retreatment system was more effective than Mani NRT-GPR system regarding removal of root filling material and also removed significantly more dentine after retreatment of curved mesial root canals of mandibular molars.Keywords: Dental Instruments; Endodontics; Gutta-Percha; Endodontic Retreatment

Inovação responsável através de fronteiras: tensões, paradoxos e possibilidades

In March 2014 a group of early career researchers and academics from São Paulo state and from the UK met at the University of Campinas to participate in a workshop on ‘Responsible Innovation and the Governance of Socially Controversial Technologies’. In this Perspective we describe key reflections and observations from the workshop discussions, paying particular attention to the discourse of responsible innovation from a cross-cultural perspective. We describe a number of important tensions, paradoxes and opportunities that emerged over the three days of the workshop

Anisotropy studies around the galactic centre at EeV energies with the Auger Observatory

Data from the Pierre Auger Observatory are analyzed to search for anisotropies near the direction of the Galactic Centre at EeV energies. The exposure of the surface array in this part of the sky is already significantly larger than that of the fore-runner experiments. Our results do not support previous findings of localized excesses in the AGASA and SUGAR data. We set an upper bound on a point-like flux of cosmic rays arriving from the Galactic Centre which excludes several scenarios predicting sources of EeV neutrons from Sagittarius $A$. Also the events detected simultaneously by the surface and fluorescence detectors (the `hybrid' data set), which have better pointing accuracy but are less numerous than those of the surface array alone, do not show any significant localized excess from this direction.Comment: Matches published versio

Measurement of the cosmic ray spectrum above 4×10184{\times}10^{18} eV using inclined events detected with the Pierre Auger Observatory

A measurement of the cosmic-ray spectrum for energies exceeding $4{\times}10^{18}$ eV is presented, which is based on the analysis of showers with zenith angles greater than $60^{\circ}$ detected with the Pierre Auger Observatory between 1 January 2004 and 31 December 2013. The measured spectrum confirms a flux suppression at the highest energies. Above $5.3{\times}10^{18}$ eV, the "ankle", the flux can be described by a power law $E^{-\gamma}$ with index $\gamma=2.70 \pm 0.02 \,\text{(stat)} \pm 0.1\,\text{(sys)}$ followed by a smooth suppression region. For the energy ($E_\text{s}$) at which the spectral flux has fallen to one-half of its extrapolated value in the absence of suppression, we find $E_\text{s}=(5.12\pm0.25\,\text{(stat)}^{+1.0}_{-1.2}\,\text{(sys)}){\times}10^{19}$ eV.Comment: Replaced with published version.

Highlights from the Pierre Auger Observatory

The Pierre Auger Observatory is the world's largest cosmic ray observatory. Our current exposure reaches nearly 40,000 km$^2$ str and provides us with an unprecedented quality data set. The performance and stability of the detectors and their enhancements are described. Data analyses have led to a number of major breakthroughs. Among these we discuss the energy spectrum and the searches for large-scale anisotropies. We present analyses of our X$_{max}$ data and show how it can be interpreted in terms of mass composition. We also describe some new analyses that extract mass sensitive parameters from the 100% duty cycle SD data. A coherent interpretation of all these recent results opens new directions. The consequences regarding the cosmic ray composition and the properties of UHECR sources are briefly discussed.Comment: 9 pages, 12 figures, talk given at the 33rd International Cosmic Ray Conference, Rio de Janeiro 201

Azimuthal asymmetry in the risetime of the surface detector signals of the Pierre Auger Observatory

The azimuthal asymmetry in the risetime of signals in Auger surface detector stations is a source of information on shower development. The azimuthal asymmetry is due to a combination of the longitudinal evolution of the shower and geometrical effects related to the angles of incidence of the particles into the detectors. The magnitude of the effect depends upon the zenith angle and state of development of the shower and thus provides a novel observable, $(\sec \theta)_\mathrm{max}$, sensitive to the mass composition of cosmic rays above $3 \times 10^{18}$ eV. By comparing measurements with predictions from shower simulations, we find for both of our adopted models of hadronic physics (QGSJETII-04 and EPOS-LHC) an indication that the mean cosmic-ray mass increases slowly with energy, as has been inferred from other studies. However, the mass estimates are dependent on the shower model and on the range of distance from the shower core selected. Thus the method has uncovered further deficiencies in our understanding of shower modelling that must be resolved before the mass composition can be inferred from $(\sec \theta)_\mathrm{max}$.Comment: Replaced with published version.
