No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências da Saúde, Programa de Pós-Graduação em Enfermagem, Florianópolis, 2009.A relação de formação de recursos humanos de Enfermagem na América Latina encontra-se intimamente relacionada aos processos de formação básica de trabalhadores da área, de Graduação e de Pós-Graduação, bem como suas especificidades e direcionamentos no setor de saúde. Neste panorama, a área da Enfermagem vem repensando seus modos de fazer, de pesquisar e de educar, refletindo avanços e mudanças nos cursos de formação profissional, no ensino, na pesquisa e nas práticas de cuidado em saúde. Esta pesquisa é do tipo descritiva, exploratório-analítica, em base documental, de natureza qualitativa, com o objetivo de analisar a produção científica dos Grupos de Pesquisa em Educação em Enfermagem da Região Sul do Brasil, configurando as tendências e perspectivas deste setor por meio da produção de artigos científicos publicados nos últimos cinco anos (2004-2008). Nesta Região existem 18 GPEE, assim distribuídos: Rio Grande do Sul (08), Santa Catarina (03) e Paraná (07). A partir da análise do currículo dos 173 pesquisadores cadastrados nestas estruturas, foram captados todos os artigos científicos de Qualis/CAPES Internacional disponíveis on-line, concretizando 330 produções. A organização e sistematização dos estudos foram assim conduzidas: 1) Captação do estudo na íntegra; 2) Leitura dos resumos e diferenciação do corpo de análise; 3) Leitura dinâmica e impregnação do trabalho completo; 4) Sistematização dos estudos no instrumento de análise. Os resultados são elucidados a partir de três manuscritos: 1) Caracterização da produção científica e tecnológica em educação em Enfermagem do Sul do Brasil; 2) Análise da produção científica dos Grupos de Pesquisa em educação em Enfermagem da Região Sul do Brasil; e 3) Posturas pedagógicas na educação em Enfermagem e saúde da Região Sul do Brasil. Os enfermeiros têm optado pelo trabalho individual, com evidente dificuldade destes GPEE em articular as pesquisas entre seus membros e de focá-las em sua temática genuína, distanciando-se do aprofundamento em educação em saúde e preocupandose com a categoria produtividade em detrimento de uma produção que dê visibilidade e contribua com sua linha de pesquisa. No entanto, os estudos cujo enfoque se mantém na educação encontram-se pautados em teorias críticas, bem como a tendência temática encontra-se sustentada na vertente currículo/formação e de educação popular. Revela-se a percepção da educação em saúde como componente crítico-reflexivo, voltada ao contexto social dos indivíduos, reconhecendo a realidade dos sujeitos, a importância do diálogo, na perspectiva de horizontalidade e voltada à cidadania. A dinâmica de trabalho dos GPEE tem resultado em produções de qualidade sobre educação em Enfermagem e saúde, no entanto, essa produção tem sido difundida de forma lenta, com baixa representatividade na Região Sul do Brasil. A produção e divulgação das práticas educativas desenvolvida no trabalho em saúde, de pesquisas e de análises de realidades, tornam-se insuficiente quando é evidenciada a potencialidade de pesquisadores que dispõe. Tornar-se-ia possível contribuir, com maior visibilidade, nas políticas de recursos humanos do âmbito latino-americano. Neste sentido, sugere-se a construção de macro-projetos dentro dos GPEE para orientar subprojetos de iniciação científica e de Pós-Graduação, orientados em acordo à necessidade social, com enfoque em educação, Enfermagem e saúde.The relation of the formation of human resources of Nursing in Latin América is intimately related to the basic formation process of workers in the area, of graduation and postgraduation, as well as its specifications and direction in the health sector. In this panorama, the area of nursing has been rethinking their working process, of research and teaching, reflecting advances and changes in the professional formation courses, of teaching, in research and care practices of health. This study is the descriptive type, exploratory-analytical, in documental base, of qualitative methodology, with the objective of analyzing the scientific production of study groups of education in nursing of the south region of Brazil, configuring the tendencies and perspectives of the sector through the means of production of scientific articles published in the last five years (2004-2008). In this region exists 18 GPEE, that are distributed in this manner: Rio Grande do Sul (08), Santa Catarina (03) and Parana (07). From the analysis of the curriculum of 173 researchers registered in this structure, all the scientific articles of International Qualis/CAPES available on-line, totalizing 330 productions. The organization and systematization of the studies were conducted in this manner: 1) Collection of the total study; 2) Reading of the abstracts and the diverse body of analysis; 3) The reading dynamics impregnation of their complete work; 4) Systematization of their studies in the instrument of analysis. The results were resolved through three manuscripts: 1) Characterization of scientific production and technology in Education of Nursing of the south of Brazil; 2) Analysis of the scientific production of the study groups in Education of Nursing of the South Region of Brazil; and 3) The pedagogy procedures in Education of Nursing and Health of the South Region of Brazil. The Nurses have been opting for individual work, with evident difficulty of GPEE in articulating research among is members and to focalize them in their genuine theme, distancing themselves in profound health education and only preoccupy with the productivity of the category in deter of a production that gives visibility and contribute to their line of research. However, the studies that focalize on education is found to be based on critical theories, as well as the thematic tendency is found to be sustained in the side of curriculum/formation and popular education. It reveals the perception in education of health as a critic-reflexive component, directed to the social context of individuals, accepting the reality of people, the importance of dialogue, in the perspective of horizontality and directed to citizens. The work dynamics of GPEE has resulted into quality productions about education in Nursing and Health, however, this production has been divulge in a slow form, with low representative in the South Region of Brazil. The production and disclosure of educative practices developed in the work of health, the research and analysis of realities, has been insufficient when it evidence the potentiality of the researchers at hand. It turns to be possible to contribute, with great visibility, in the political of human resources in the ambit of Latin-America. In this sense, suggest the construction of macro-projects inside the GPEE to orientate subprojects of scientific initiations and post-graduation, supervise in accord with social necessity, with focus in education, Nursing and Health
Description of atmospheric conditions at the Pierre Auger Observatory using the Global Data Assimilation System (GDAS)
No full textAtmospheric conditions at the site of a cosmic ray observatory must be known for reconstructing observed extensive air showers. The Global Data Assimilation System (GDAS) is a global atmospheric model predicated on meteorological measurements and numerical weather predictions. GDAS provides altitude-dependent profiles of the main state variables of the atmosphere like temperature, pressure, and humidity. The original data and their application to the air shower reconstruction of the Pierre Auger Observatory are described. By comparisons with radiosonde and weather station measurements obtained on-site in Malargüe and averaged monthly models, the utility of the GDAS data is shown. © 2012 Elsevier B.V.

Limit on the diffuse flux of ultrahigh energy tau neutrinos with the surface detector of the Pierre Auger Observatory
No full textData collected at the Pierre Auger Observatory are used to establish an upper limit on the diffuse flux of tau neutrinos in the cosmic radiation. Earth-skimming nu(tau) may interact in the Earth's crust and produce a tau lepton by means of charged-current interactions. The tau lepton may emerge from the Earth and decay in the atmosphere to produce a nearly horizontal shower with a typical signature, a persistent electromagnetic component even at very large atmospheric depths. The search procedure to select events induced by tau decays against the background of normal showers induced by cosmic rays is described. The method used to compute the exposure for a detector continuously growing with time is detailed. Systematic uncertainties in the exposure from the detector, the analysis, and the involved physics are discussed. No tau neutrino candidates have been found. For neutrinos in the energy range 2x10(17) eV < E(nu)< 2x10(19) eV, assuming a diffuse spectrum of the form E(nu)(-2), data collected between 1 January 2004 and 30 April 2008 yield a 90% confidence-level upper limit of E(nu)(2)dN(nu tau)/dE(nu)< 9x10(-8) GeV cm(-2) s(-1) sr(-1)
Calibration of the underground muon detector of the Pierre Auger Observatory
No full textTo obtain direct measurements of the muon content of extensive air showers with energy above 101 eV, the Pierre Auger Observatory is currently being equipped with an underground muon detector (UMD), consisting of 219 10 m2-modules, each segmented into 64 scintillators coupled to silicon photomultipliers (SiPMs). Direct access to the shower muon content allows for the study of both of the composition of primary cosmic rays and of high-energy hadronic interactions in the forward direction. As the muon density can vary between tens of muons per m close to the intersection of the shower axis with the ground to much less than one per m when far away, the necessary broad dynamic range is achieved by the simultaneous implementation of two acquisition modes in the read-out electronics: the binary mode, tuned to count single muons, and the ADC mode, suited to measure a high number of them. In this work, we present the end-to-end calibration of the muon detector modules: first, the SiPMs are calibrated by means of the binary channel, and then, the ADC channel is calibrated using atmospheric muons, detected in parallel to the shower data acquisition. The laboratory and field measurements performed to develop the implementation of the full calibration chain of both binary and ADC channels are presented and discussed. The calibration procedure is reliable to work with the high amount of channels in the UMD, which will be operated continuously, in changing environmental conditions, for several years.Fil: Aab, A..

Design, upgrade and characterization of the silicon photomultiplier front-end for the AMIGA detector at the Pierre Auger Observatory
No full textAMIGA (Auger Muons and Infill for the Ground Array) is an upgrade of the Pierre Auger Observatory to complement the study of ultra-high-energy cosmic rays (UHECR) by measuring the muon content of extensive air showers (EAS). It consists of an array of 61 water Cherenkov detectors on a denser spacing in combination with underground scintillation detectors used for muon density measurement. Each detector is composed of three scintillation modules, with 10 m2 detection area per module, buried at 2.3 m depth, resulting in a total detection area of 30 m2 . Silicon photomultiplier sensors (SiPM) measure the amount of scintillation light generated by charged particles traversing the modules. In this paper, the design of the front-end electronics to process the signals of those SiPMs and test results from the laboratory and from the Pierre Auger Observatory are described. Compared to our previous prototype, the new electronics shows a higher performance, higher efficiency and lower power consumption, and it has a new acquisition system with increased dynamic range that allows measurements closer to the shower core. The new acquisition system is based on the measurement of the total charge signal that the muonic component of the cosmic ray shower generates in the detector.Fil: Aab, A..

A Targeted Search for Point Sources of EeV Photons with the Pierre Auger Observatory
No full textSimultaneous measurements of air showers with the fluorescence and surface detectors of the Pierre Auger Observatory allow a sensitive search for EeV photon point sources. Several Galactic and extragalactic candidate objects are grouped in classes to reduce the statistical penalty of many trials from that of a blind search and are analyzed for a significant excess above the background expectation. The presented search does not find any evidence for photon emission at candidate sources, and combined p-values for every class are reported. Particle and energy flux upper limits are given for selected candidate sources. These limits significantly constrain predictions of EeV proton emission models from non-transient Galactic and nearby extragalactic sources, as illustrated for the particular case of the Galactic center region

Large-scale distribution of arrival directions of cosmic rays detected above 10(18) ev at the Pierre Auger observatory
No full textA thorough search for large-scale anisotropies in the distribution of arrival directions of cosmic rays detected above 10¹⁸ eV at the Pierre Auger Observatory is presented. This search is performed as a function of both declination and right ascension in several energy ranges above 10¹⁸ eV, and reported in terms of dipolar and quadrupolar coefficients. Within the systematic uncertainties, no significant deviation from isotropy is revealed. Assuming that any cosmic-ray anisotropy is dominated by dipole and quadrupole moments in this energy range, upper limits on their amplitudes are derived. These upper limits allow us to test the origin of cosmic rays above 10¹⁸ eV from stationary Galactic sources densely distributed in the Galactic disk and predominantly emitting light particles in all directions.The Pierre Auger Collaboration, P.
