    Among the analysis techniques by ions beams, the micro ERDA (Elastic Detection Analysis) is an interesting technique which allows the quantitative distribution of the hydrogen in materials. In particular, this analysis has been used for hydride zirconium alloys, with the nuclear microprobe of the Laboratory Pierre Sue. This probe allows the characterization of radioactive materials. The technique principles are recalled and then two examples are provided to illustrate the fuel clad behavior in PWR reactors. (A.L.B.)

    Introduction Afin d’évaluer une grille de contrôle standardisée de laboratoire de diagnostic des leishmanioses, comme nouveau outil de supervision. Méthodes Un essai pilote a été pratiqué sur sept laboratoires provinciaux, appartenant à quatre provinces au Maroc, en suivant l’évolution de leurs performances tous les deux ans, entre l’année 2006 et 2014. Cette étude détaille la situation des laboratoires provinciaux avant et après la mise en œuvre de la grille de supervision. Au total vingt et une grille sont analysées. Résultats En 2006, les résultats ont montré clairement une insuffisance des performances des laboratoires: besoin en formation (41.6%), personnel pratiquant le prélèvement cutané (25%), pénurie en matériels et réactifs (65%), gestions documentaire et local non conformes (85%). Différentes actions correctives ont été menées par le Laboratoire National de Référence des Leishmanioses (LNRL) durant la période d’étude. En 2014, le LNRL a enregistré une nette amélioration des performances des laboratoires. Les besoins en matière de formation, qualité du prélèvement, dotation en matériels et réactifs ont été comblés et une coordination efficace s’est établie entre le LNRL et les laboratoires provinciaux. Conclusion Ceci montre l'efficacité de la grille comme outil de supervision de grande qualité, et comme pierre angulaire de tout progrès qui doit être obtenu dans les programmes de lutte contre les leishmanioses.

    The Pierre Auger project is a broadly based international effort to make a detailed study of cosmic rays at the highest energies. Two air shower detectors are proposed, one to be placed in the Northern Hemisphere and one in the Southern Hemisphere. Each installation will consist of an array of 1600 particle detectors spread over 3000 km 2 with a solid angle acceptance of 2 sr for cosmic ray air showers. Eah installation will also have an atmospheric fluorescence detector viewing the volume above the surface array. These two air shower detector techniques working together form a powerful instrument for the proposed research. The objectives of the Pierre Auger project are to measure the arrival direction, energy, and mass composition of 60 events per year above an energy of 10 20 eV and 6000 events per year above 10 19 eV. A collaboration is now being formed with the goal of having the Pierre Auger observatory in operation by 2001

    After difficult beginnings as a farm boy in Brittany, and then as a dish-washer at a chemist's in Paris, Pierre Famel (1855-1934) obtained his grammar certificate in 1879 and then his 2nd class chemist diploma from the Ecole de pharmacie de Paris in 1885. He was employed by the Laboratoire municipal de la Ville de Paris as an expert chemist. In 1886 he set himself up in a pharmacy at 86, rue de la Réunion, in Paris, known as the Pharmacie Famel. In 1912 he created the Laboratoires Famel for the manufacture of pharmaceutical products with sales representation in several European, North and South American as well as Canadian cities. He marketed among other things Famel Syrup, Famel suppositories, Langlebert glycophosphated wine, Sulfogène Famel and Optraex. The Famel firm obtained several awards at Exhibitions in France and elsewhere. On the death of Pierre Famel, the dispensary was sold, while his daughter and his granddaughter formed a partnership to manage the Laboratories. They still exist today as a finance company, the main activity of which is the management of its heritage. Pierre Famel was a foreign trade adviser, a vice-president of the Franco-Czechoslovakian and Franco-Iranian Chambers of Commerce. He created a prize for commercial attachés, as well as annual fellowships for students from foreign medical faculties. He was a sponsor of several youth clubs and charitable organizations, as well as a member of several Breton associations. He was the President of the Society of the Friends of the Pharmacology Faculty in Paris as well as the founder of the Museum devoted to Henri Moissan, the first French winner of the Nobel Price in Chemistry, who was for him a guide and a teacher in his early life and studies. He was a Commander of the Legion of Honour (1925) and was awarded the Gold Medal of foreign trade (1933). Also briefly mentioned are his wife, Marie Famel, an enamel painter, his daughter Yvonne Famel, and his son-in-law, Sylvain Rosengart, with whom

    Full Text Available The recent work of Pierre Bayard is trenchant, original, and deeply engaging. From Qui a tué Roger Ackroyd? (1998 Who Killed Roger Ackroyd? (2001 onward, Bayard's books have piqued the interest of readers well beyond the limited circle of those who habitually consume French criticism and literary theory, and have served thus to expand the horizon of possibility of critical writing in significant ways. Bayard writes in a conditional, hypothetical mode, rather than a declarative one, keenly aware of how very mobile literary objects are. Bayard is not afraid to take risks, and he searches for new forms through a process of bold experimentation. He seeks moreover to enlist his reader in that quest, proposing a contract to him or her, one whose principal clauses are articulative and ludic. Fictional worlds are incomplete, he argues, and we readers must intervene in them in order to palliate that incompletion, through our interpretations. We accede to fictional worlds through wormholes, passages joining places that are thought to be unconnected. With this interventionist model, Bayard encourages us to reconsider the way that we read fiction, and also the way that we read critical writing.

    Full Text Available O presente texto procura discutir o legado deixado pelo sociólogo francês Pierre Bourdieu. Dez anos após sua morte, tem-se discutido, em nível internacional, a relevância deste autor, um dos mais influentes e citados teóricos do mundo. Para a identificação desta influência no Brasil, mais especificamente no campo educacional brasileiro, pesquisou-se nas teses e dissertações encontradas no banco de dados da CAPES, que referenciavam Bourdieu, de que forma estaria se dando a apropriação de seu quadro teórico de análise para construção de conhecimento no referido campo. Concluiu-se que o número de produções defendidas nos Programas de Pós-Graduação em Educação no Brasil, de 1965 a 2010, cresce de forma exponencial, demonstrando o quão profícua a utilização da teoria sociológica de Bourdieu tem se mostrado para explicar a realidade da Educação no Brasil na contemporaneidade. Encerra-se o artigo com uma reflexão sobre a consideração do status de Bourdieu como um clássico da Sociologia que, paradoxalmente, se mostra mais atual e vivo do que qualquer outro autor quando se trata de aplicar seu princípio maior, a saber, analisar o mundo social e suas lógicas, desvelando as formas de dominação e as misérias sociais.This paper's intent is to discuss the legacy left by the French sociologist Pierre Bourdieu. Ten years after his death, it has been discussed at an international level the relevance of this author, one of the most cited and influential theorists in the world. To identify such influence in Brazil, more specifically in the Brazilian educational field, we investigated theses and dissertations found in CAPES database, which referenced Bourdieu, to identify how those works use his theoretical framework of analysis for construction of knowledge in that field. It was concluded that the number of productions held in post-graduate programs in education in Brazil, from 1965 to 2010, grows exponentially

Los pacientes con la forma idiopática, especialmente los que tienen alterados el SPECT del transportador de la dopamina, la sonografía de la sustancia negra, los test de olfato y de la visión de colores, tienen un elevado riesgo de desarrollar la E P, DCL y AMS. El TCSR no debe considerarse como un simple trastorno del sueño, sino como una manifestación de una enfermedad neurológica. El clonazepam (0.25-4 mg y la melatonina (3-12 mg a la hora de acostarse mejoran los síntomas del TCSR pero no evitan, en la forma idiopática, la conversión a una enfermedad neurodegenerativa.

  20. Adenosina y control homeostático del sueño: Acciones en estructuras diana de los circuitos de vigilia y sueño

    La homeostasis del sueño se manifiesta ante situaciones de vigilia prolongada de forma natural o experimentalmente. En estos casos, se presenta somnolencia (o presión de sueño) y, cuando se permite dormir, hay un rebote del sueño en duración e intensidad que compensa la pérdida del mismo. Entre las moléculas que pueden intervenir en la regulación homeostática del sueño, se encuentra la adenosina, cuyos antagonistas, la cafeína y la teofilina, consume la población humana ampliament...

  1. Marie and Pierre Curie. Life in extremes

    Roethlein, Brigitte

    2008-01-01

    In Paris in 1894, two young physicists fall in love: Marie Sklodowska and Pierre Curie. They get married and make great contributions to science, research radioactivity and discover new chemical elements. The marriage of Marie and Pierre Curie is quite modern: They work together as equals, share their thoughts and pursue their plans together as partners. They share an absolute interest in science, a love of nature, and a sceptic attitude towards the sophisticated society of the Belle Epoque. They are together 24 hours a day with hardly ever any disagreement. Whenever one of them is ill - which is quite often because of the high level of radioactivity in their laboratory -, the other will nurse him or her. After only twelve years of mutual love, Pierre Curie dies. Marie raises their two daughters on her own and continues her research. In 1911, she will be the first scientist that ever gets a second Nobel Prize. (orig.) [de

    This book relates the life and works of the most famous married couple of scientists. Their works have completely overturned the science of the 20. century and their discovery of radium was rewarded by the Nobel price in 1903. This marriage both in science and life ended three years later because of a banal accident: Pierre Curie is fatally knocked down by a horse carriage in Paris. (J.S.)

    While the work to make data acquisition fully automatic continues, both the Fluorescence Detectors and the Surface Detectors of the Pierre Auger Observatory need some kind of attention from the local staff. In the first case, the telescopes are operated and monitored during the moonless periods. The ground array only needs monitoring, but the larger number of stations implies more variables to consider. AugerAccess (a high speed internet connection) will give the possibility of operating and monitoring the observatory from any place in the world. This arises questions about secure access, better control software and alarms. Solutions are already being tested and improved.

    The Pierre Auger observatory is a hybrid air shower experiment which uses multiple detection techniques to investigate the origin, spectrum, and composition of ultrahigh energy cosmic rays. We present recent results on these topics and discuss their implications to the understanding the origin of the most energetic particles in nature as well as for physics beyond the Standard Model, such as violation of Lorentz invariance and 'top-down' models of cosmic ray production. Future plans, including enhancements underway at the southern site in Argentina will be presented. (author)

    Full Text Available This work presents a diachronic study of Pierre Schaeffer’s texts from 1942, 1950 and 1966. It shows the mechanics of his theory of listening, following in the author’s footsteps to highlight the creation of concepts by accumulation, a procedure he takes to extremes in the notion of quatre fonctions de l’écoute. One concludes that écoute réduite is not a compositional aesthetics but rather a poetics of aural perception.

    In the frame of the French Metrology Institute, the Laboratoire National Henri Becquerel performs accurate characterization of semiconductor detectors that are in use in a number of applications. Their efficiency calibration, energy resolution and the detailed shape of their response function are parameters of interest for accurate processing of low-energy X-ray spectra to be applied to elements identification and fundamental research studies. The tools specifically developed for low-energy detectors calibration and characterization are described, from the use of radioactivity standard to the development of a tunable monochromatic X-ray source.

    Full Text Available El objetivo de este estudio es, por una parte, determinar las características de personalidad entre individuos que recuerdan sueños y, por otra, comparar las puntuaciones obtenidas en la alteración dormital, el neuroticismo y la extroversión, y los indicadores de propensión a la esquizotipia en individuos que no recuerdan sueños. Para este fin, se examinó la frecuencia del recuerdo del sueño con contenido extraño, inusual, y anómalo-paranormal. Vale la pena resaltar que pocos estudios han explorado las diferencias individuales en relación con tales sueños. En este estudio se reagrupó una muestra de 231 individuos de ambos sexos que puntuaron su calidad en el recuerdo del sueño entre alta (n = 57 y baja (n = 174. Se emplearon tres instrumentos que miden la etapa dormital y dos que miden el neuroticismo, la extroversión y la esquizotipia. Los sueños exóticos más frecuentes son los auditivos, los lúcidos, los recurrentes, los psíquicos y los asociados al recuerdo de personas fallecidas. Las puntuaciones altas en la alteración del sueño, las experiencias esquizotípicas y las experiencias hipnagógicas e hipnopómpicas caracterizan a los soñadores en comparación con los no soñadores. Este estudio sostiene la idea de que ciertos indicadores de propensión a la esquizotipia están asociados a la frecuencia del recuerdo de sueños exóticos.

    Pierre Auger Observatory operates the largest system of detectors for ultra-high energy cosmic ray measurements. Comparison of theoretical models of interactions with recorded data requires thousands of computing cores for Monte Carlo simulations. Since 2007 distributed resources connected via EGI grid are successfully used. The first and the second versions of production system based on bash scripts and MySQL database were able to submit jobs to all reliable sites supporting Virtual Organization auger. For many years VO auger belongs to top ten of EGI users based on the total used computing time. Migration of the production system to DIRAC interware started in 2014. Pilot jobs improve efficiency of computing jobs and eliminate problems with small and less reliable sites used for the bulk production. The new system has also possibility to use available resources in clouds. Dirac File Catalog replaced LFC for new files, which are organized in datasets defined via metadata. CVMFS is used for software distribution since 2014. In the presentation we give a comparison of the old and the new production system and report the experience on migrating to the new system.

    2017-06-01

    Full Text Available Although Pierre Duhem is well known for his conventionalist outlook and, in particular, for his critique of crucial experiments outlined in his thesis on the empirical indeterminacy of theory, he also contributed to the scholarship on the psychological profiles of scientists by revising Pascal’s famous distinction between the subtle mind and the geometric mind (esprits fins and esprits géométriques. For Duhem, the ideal scientist is the one who combines the defining qualities of both types of intellect. As a physicist, Duhem made important theoretical contributions to the field of thermodynamics as well as to the then-nascent physical chemistry. Due to his rejection of atomism and his unrelenting critique of Maxwell’s electrodynamics, however, in his later years, Duhem’s work was surpassed and abandoned by the dominant tendencies of physics of the time. In this essay, I will discuss whether Duhem himself can be understood through the lens of his own account of the scientist’s psychological profile. More specifically, I examine whether the subtle mind – to which he seems to assign greater cognitive value – in fact plays a key role in Duhem’s critique of the English School (école anglaise, or if his preference for the axiomatic structure of theoretical physics shows a greater affinity with the geometric mind.

You are not hurt, but the car is a write-off…   Fortunately, you will not lose out. A car's safety is the responsibility of the manufacturer and you can sue them for compensation. Even worse for them, if it turns out to be a design flaw they will need to recall and fix all the cars of that model – at their expense.

  14. Evaluation of excavation experience: Pierre shale. Final report

    Pierre shale and its stratigraphic equivalents represent a potentially favorable geologic environment for underground storage of hazardous waste products. These rock formations cover great areal and vertical extents, and represent some of the least permeable rock formations within the continental United States. There are, however, several engineering problems associated with constructing underground openings in Pierre shale. This formation is relatively weak and tends to deteriorate rather rapidly if not protected from the mine environment. It will be necessary to place all underground openings below the surficially weathered upper 50 to 70 feet of Pierre shale which contains groundwater moving on fracture permeability. The optimum site for disposal of hazardous waste in Pierre shale, or its stratigraphic equivalents, would be a seismically stable platform bounded on all sides by faults. The optimum size of individual openings would be the minimum necessary for access, storage, and retrieval of waste components. Underground excavations in Pierre shale must be made with care, must be of limited dimensions, must be widely spaced, must be protected from prolonged contact with the mine environment, must be supported immediately after excavation, and must be sited to avoid areas of faulting and(or) intense jointing. Underground openings constructed with boring machines and supported with wet shotcrete are recommended

    The radioactivity levels in the air of the radionuclides released by the Fukushima accident were measured at the Laboratoire Souterrain de Modane, in the South-East of France, during the period 25 March-18 April 2011. Air-filters from the ventilation system exposed for one or two days were measured using low-background gamma-ray spectrometry. In this paper we present the activity concentrations obtained for the radionuclides (131)I, (132)Te, (134)Cs, (137)Cs, (95)Nb, (95)Zr, (106)Ru, (140)Ba/La and (103)Ru. The activity concentration of (131)I was of the order of 100 μBq/m(3), more than 100 times higher than the activities of other fission products. The highest activities of (131)I were measured as a first peak on 30 March and a second peak on 3-4 April. The activity concentrations of (134)Cs and (137)Cs varied from 5 to 30 μBq/m(3). The highest activity concentration recorded for Cs corresponded to the same period as for (131)I, with a peak on 2-3 April. The results of the radioactivity concentration levels in grass and mushrooms exposed to the air in the Modane region were also measured. Activity concentrations of (131)I of about 100 mBq/m(2) were found in grass. Copyright © 2012 Elsevier Ltd. All rights reserved.

  20. Relaciones entre el sueño y la adicción

    Resumen La interacción entre los trastornos del sueño y el abuso de sustancias es ya conocida, pero seguramente más compleja de lo que se pensaba. Existe tanto una relación positiva entre tener un trastorno por uso de substancias y sufrir un trastorno de sueño, como viceversa. Los efectos sobre el sueño dependen de la substancia utilizada, pero se ha demostrado que tanto durante su uso como en período de abstinencia los consumidores tienen diferentes problemas de sueño y fundamentalmente un sueño más fragmentado. Sabemos que hay que tener en cuenta los problemas de sueño para evitar recaídas en la adicción. Investigaciones recientes indican que el sistema hipocretinérgico definido por el neuropéptido hipocretina/orexina (Hcrt/ox), localizado en el hipotálamo lateral e implicado entre otros en la regulación del ciclo sueño-vigilia, jugaría un papel importante en las conductas adictivas. Diferentes estudios han demostrado interacciones entre el sistema hipocretinérgico, los circuitos de respuesta aguda al estrés y los sistemas de recompensa. También sabemos que la activación optogenética selectiva del sistema hipocretinérgico incrementa la probabilidad de la transición del sueño a la vigilia, y también es suficiente para iniciar un comportamiento compulsivo de recaída adictiva. La activación del sistema hipocretinérgico podría explicar la hipervigilia asociada al estrés y a la adicción. El mayor conocimiento de esta interacción permitiría entender mejor los mecanismos de la adicción y encontrar nuevas estrategias para el tratamiento de las adicciones. PMID:23241715

  10. Supinator Extender (SUE): a pneumatically actuated robot for forearm/wrist rehabilitation after stroke.

    2011-01-01

    The robot described in this paper, SUE (Supinator Extender), adds forearm/wrist rehabilitation functionality to the UCI BONES exoskeleton robot and to the ArmeoSpring rehabilitation device. SUE is a 2-DOF serial chain that can measure and assist forearm supination-pronation and wrist flexion-extension. The large power to weight ratio of pneumatic actuators allows SUE to achieve the forces needed for rehabilitation therapy while remaining lightweight enough to be carried by BONES and ArmeoSpring. Each degree of freedom has a range of 90 degrees, and a nominal torque of 2 ft-lbs. The cylinders are mounted away from the patient's body on the lateral aspect of the arm. This is to prevent the danger of a collision and maximize the workspace of the arm robot. The rotation axis used for supination-pronation is a small bearing just below the subject's wrist. The flexion-extension motion is actuated by a cantilevered pneumatic cylinder, which allows the palm of the hand to remain open. Data are presented that demonstrate the ability of SUE to measure and cancel forearm/wrist passive tone, thereby extending the active range of motion for people with stroke.

Para demostrarlo, el autor ofrece una serie de casos etnográficos concretos en los que los sueños participan en los procesos de comunicación, aprendizaje y comprensión de los interrogantes formulados en cada abordaje antropológico. A su vez, se exponen hechos de la investigación del propio autor entre los indígenas muina (uitoto y muinane de la Amazonia colombiana, en los que algunos sueños propios y de algunos indígenas abrieron rutas de discusión que pusieron al descubierto conceptos y discursos que auxiliaron la comprensión de la realidad y las actuaciones sobre ella. Finalmente, el autor discute cómo algunas experiencias vitales vividas en el proceso de investigación, como los sueños en este caso, constituyen una pertinente contribución a los debates sobre los desafíos contemporáneos del quehacer etnográfico.

A escola, a cultura, a economia foram, entre outros, estudadas aplicando conceitos novos na sociologia, tais como habitus, violência simbólica ou campo social. Propondo uma nova leitura das relações sociais, Bourdieu criou um modo de pensar suscitando criticas severas, mas também uma obra profícua utilizada nos mais variados setores sociais.Through a chronological presentation of Bourdieu's work, we tried to extract his ideas and the theoretical elements and concepts he formulated.

    Pierre Robin sequence (formerly a syndrome) is named after the French stomatologist who, in 1923 and 1934, described the problems associated with micrognathia in newborn. It comprises mandibular micrognathia, U-shaped cleft palate, and glossoptosis. The typical symptoms are hypoxaemia, noisy breathing, snoring, stridor, cyanosis, bradycardia, feeding difficulties, and failure to thrive. Distraction osteogenesis has recently been considered as a surgical option for early intervention to lengthen the mandible and relieve respiratory problems. Piezosurgery offers a modality to make precise bone cuts preserving vital structures, minimizing the invasiveness of the surgical procedure, and offering bloodless field.

  5. Places de Max Weber et Gaston Bachelard chez Pierre Bourdieu

    OpenAIRE

    2005-01-01

    Can we better understand Pierre Bourdieu's sociology by appealing to the intellectual references he made use of in his works? Not really, because confronting Bourdieu with the classical sources he relies on, as Marx, Weber or Bachelard, the reader can note a rather lax exercise of the concepts he is borrowing and he is making his. Or, this insight in Bourdieu's work takes the opposite way, as it tries to analytically read Bourdieu intellectual project on building sociology as science by start...

    The authors described the general principles governing the design of a laboratory for experimenting and handling radioactive substances. The difficulties encountered are of two types: 1) those due to the dangers of external irradiation; 2) those due to the dangers of internal contamination. As an example, the authors describe the French achievements in this field and in particular: - the high-activity laboratories at Saclay; - the laboratory for the examination of irradiated fuels at Saclay; - the 'hot' laboratory of the CEN-Grenoble; - the alpha, beta and gamma laboratories of the CEN-Fontenay-aux-Roses. Finally, the report describes the protective materials used for these installations. (author) [French] Les auteurs exposent quels sont les principes generaux qui president a la conception d'un laboratoire a des travaux et des manipulations sur des substances radioactives. Les difficultes a surmonter sont de deux ordres: 1) celles qui proviennent du danger d'irradiation externe; 2) celles qui proviennent du danger de contamination interne. A titre d'exemple, les auteurs decrivent les realisations francaises dans ce domaine et en particulier: - le laboratoire de haute activite de Saclay, - le laboratoire d'examen des combustibles irradies de Saclay, - le laboratoire chaud du CEN-Grenoble, - les laboratoires alpha, beta, gamma du CEN-Fontenay-aux-Roses. Enfin, le rapport decrit les materiaux de protection mis en oeuvre pour ces realisations. (auteur)

    Conclusiones de los autores: Un estudio pequeño no logró encontrar una diferencia entre dos técnicas quirúrgicas, aunque el retorno a la dieta fue más frecuente en el grupo tratado con adenoidectomía y amigdalectomía por radiofrecuencia controlada con temperatura. En la actualidad, aún se discute sobre los criterios requeridos para diagnosticar la apnea obstructiva del sueño significativa en niños. Además, la historia natural de la enfermedad no se ha delineado por completo. Faltan ensayos controlados aleatorios que investiguen la eficacia del tratamiento de la apnea obstructiva del sueño confirmada con amigdaloadenoidectomía en niños. Se necesitan más estudios antes de efectuar recomendaciones para el tratamiento de la apnea obstructiva del sueño en niños. La calidad de la investigación en esta área podría mejorarse con el uso de estudios del sueño al inicio para determinar el grado de gravedad de la apnea del sueño en niños que se incorporan a los estudios en esta área. También se necesita un seguimiento a largo plazo para explorar el efecto de la amigdaloadenoidectomía en la apnea del sueño pediátrica.

  9. Hacia una fenomenología negativa de los sueños

    2009-04-01

    Full Text Available In the first part of the essay, I describe phenomenologically the transition between dreaming and wakefulness in order to determine whether a reliable dream memory can result from this transition (after all, we have no evidence of our dreams other than our memories. This description shows that this is indeed the case and indicates the conditions under which we can apprehend dreams without imposing on them meanings they do not have. These conditions, or “attitude” is theoretically supported by a negative phenomenology of dreams, namely, a phenomenology which describes dreams by stating what they are not. This first part also explains why we usually forget our dreams and accounts for the cases in which we are conscious of dreaming. In the second part I sketch out a negative phenomenology. This phenomenology shows that the attributions consisting in qualifying dreams, or assigning them hidden originary meanings in need of deciphering (or interpreting, or their own teleology, as well as certain positive attributions (i.e. those that start by affirming: “dreams are such and such” are nonsensical. The conclusions demonstrate the continuity between the “threshold or transitional phenomenology” developed in the first part, and the negative phenomenology developed in the second.En la primera parte del ensayo, describo fenomenológicamente la transición entre el soñar y la vigilia, a fin de determinar si de este umbral puede resultar un recuerdo-de-sueño fiable (pues no tenemos otra evidencia sobre los sueños sino nuestros recuerdos. La descripción muestra que sí y señala a la vez las condiciones requeridas para aprehender los sueños de modo de no inocularles determinaciones que les son ajenas. La “actitud” así sugerida encuentra su expresión teórica en una fenomenología negativa de los sueños, es decir, una fenomenología que sólo los describe por aquello que no son.

    2011-01-01

    Pierre-Joseph Proudhon’s ideas on credit and money have been considered to be not very relevant and above all unrealistic. However, they have known an uncommon posterity. They influenced Silvio Gesell who is John Maynard Keynes’s reference. This article analyses Pierre-Joseph Proudhon’s exchange bank plan. We show that Pierre- Joseph Proudhon’s ideas on credit and money are opened to criticism but require a reexamination because we can draw many lessons from them.

    2002-03-01

    Full Text Available Este artículo pretende mostrar las huellas que quedan, en "La interpretación de los sueños", del proceso de elaboración de duelo en Sigmund Freud por la muerte de su padre.La lectura de esta magna obra se hizo paralela a la correspondencia que Freud sostuvo con Wilhelm Fliess, sobre el tema de los sueños, entre 1896 y 1899. Se hace un rastreo de los propios sueños de Freud, teniendo en consideración que ellos son la columna vertebral de la obra con la cual el autor ilustra asuntos teóricos específicos. Sin embargo el propósito de este comentario no es abordar la parte conceptual de la obra sino más bien, hacer una aproximación a lo que ésta implicó en la vida misma del autor.

    Full Text Available Los cambios experimentados durante el siglo XIX en ámbitos corno el educativo, el social o el político, propiciarán que la educación física y el deporte se acerquen de manera ineludible al fenómeno del Olimpismo como forma de desarrollo cultural El instaurador de los Juegos Olímpicos modernos, Pierre de Coubertin, aparece en escena a finales del siglo XIX en un momento en el que bullen todas estas reflexiones pedagógicas sobre el hecho deportivo, de la que él mismo es un excelente teórico, faceta esta en la que se ha estudiado escasamente en nuestro país. La cuestión educativa, pese a lo que pudiera considerarse, se hace extensiva a toda la sociedad en su conjunto, creando para ellos universidades populares, donde todas las capas sociales podían acceder al hecho cultural. Además de reivindicar el valor educativo del discurso de Coubertin, los autores plantean una reflexión del discurso olímpico en nuestros días, señalando una lectura educativa con respecto al extendido deporte espectáculo.Changes that have happened in the 19th century regarding education and politics resulted in a closer approach of Pierre de Coubertin to Olympic games as way «f cultural development. Pierre de Coubertin, founded the Modern Olympic games at the end of 1 9 century. At that time there were pedagogical reflections about sports. Coubertin is, as well, an excellent sport theoretician. In our country, there is a lack of studies about this fact. The educational issue extends to the society as a whole, creating courses where any social stratum could study. Apart from claiming, the educational value of Coubertain's theory, authors bring up reflections about the Olympic theory, showing an educational view of sport entertainment.

    Full Text Available In this article we will discuss measurements of the longitudinal development of air showers at the Pierre Auger Observatory. The longitudinal development of the electromagnetic component can be directly observed by the fluorescence telescopes of the Auger Observatory and we will present the results on the evolution of the average shower maximum and its fluctuations as a function of energy. Moreover, two observables from the surface detector, the asymmetry of the rise time of the station signals and the muon production depth, will be discussed and the measurements will be compared to predictions from air shower simulations for different primary particle types.

    A 3-month-old male infant with clinical and radiological features of Kniest disease is reported. Additional findings were severe Pierre Robin syndrome and external hydrocephalus. The patient was retarded in mental and motor development. He died at 4 months of age from the complications of tracheostomy. The parents were both normal clinically and radiologically, thus the disease in the child was presumably due to a new mutation. The reported familial cases of Kniest disease suggest autosomal dominant inheritance. The differential diagnosis is discussed in detail. (orig.)

The course was given at a time when Bourdieu’s work had reached full maturity, and it completed, at the most generic level of significance —in the “geometral of all perspectives”— the analytical potential opened up by the main categories he used to approach the social world: habitus, field and, above all, capital or symbolic power, the true core of uncontested legitimacy and of the omnipresent domination that the state has acquired in the contemporary world.

    Full Text Available Los trastornos del sueño en niños son frecuentes y afectan el desarrollo neurológico. Los sindromes de apnea obstructiva del sueño y piernas inquietas se destacan por sus efectos cognitivo-conductuales. Los Trastornos del neurodesarrollo, como Autismo, Síndrome Déficit Atención/hiperactividad (TDAH y las co-morbilidades asociadas, presentan alta prevalencia de trastornos del sueño, con dificultades para conciliar el sueño e incremento de los despertares nocturnos, los que frecuentemente pasan desapercibidos para el médico. La consecuencia es una reducción de la alerta para las actividades diarias con incremento de trastornos conductuales, problemas emocionales y dificultades académicas asociadas a disfunción ejecutivas y de memoria, síntomas que pueden empeorar con tratamientos solo para trastorno primario. La evaluación del sueño debe formar parte sistemática en la valoración clínica de los niños con problemas cognitivo-conductuales, con el fin de realizar un diagnóstico y un tratamiento adecuados a cada caso, permitiendo mejorar la calidad de vida del niño y de su familia.

    2003-01-01

    Full Text Available El presente artículo revisa el estado actual de la investigación sobre los efectos terapéuticos de la privación de sueño en la depresión. El 40-60% de los sujetos depresivos mejora su estado clínico después de una noche de privación total de sueño. Sin embargo, la respuesta antidepresiva es transitoria. Se produce generalmente una recaída después del sueño de recuperación. Otras manipulaciones del sueño también han mostrado propiedades antidepresivas como la privación parcial de sueño, la privación selectiva de la fase de sueño MOR (con movimientos oculares rápidos y el avance del ciclo sueño-vigilia. El momento y la duración del efecto terapéutico varían en las diferentes manipulaciones del sueño. Se han propuesto diversas teorías para explicar el efecto antidepresivo de la privación de sueño. Hasta el momento el mecanismo de acción no ha sido esclarecido. Ninguna teoría propone un mecanismo de acción a la base del efecto antidepresivo de la privación de sueño que explique todos los datos empíricos existentes. El gran interés clínico y teórico de toda esta serie de resultados pone de manifiesto la necesidad de seguir investigando en las complejas pero evidentes relaciones entre los procesos que regulan el sueño y los que regulan el estado de ánimo.

  6. Ultrahigh Energy Neutrinos at the Pierre Auger Observatory

    2013-01-01

    Full Text Available The observation of ultrahigh energy neutrinos (UHEνs has become a priority in experimental astroparticle physics. UHEνs can be detected with a variety of techniques. In particular, neutrinos can interact in the atmosphere (downward-going ν or in the Earth crust (Earth-skimming ν, producing air showers that can be observed with arrays of detectors at the ground. With the surface detector array of the Pierre Auger Observatory we can detect these types of cascades. The distinguishing signature for neutrino events is the presence of very inclined showers produced close to the ground (i.e., after having traversed a large amount of atmosphere. In this work we review the procedure and criteria established to search for UHEνs in the data collected with the ground array of the Pierre Auger Observatory. This includes Earth-skimming as well as downward-going neutrinos. No neutrino candidates have been found, which allows us to place competitive limits to the diffuse flux of UHEνs in the EeV range and above.

Por el contrario está en desacuerdo con ese mismo autor en la consideración de que en el futuro será el "sueño europeo". El autor considera que en el horizonte se atisban indicios que posibilitan afirmar que el porvenir será latinoamericano. La implementación del orden feudal, frente al cosmos abierto de la reforma protestante, realizada por la colonización española, así como la inexistencia de una clase social burguesa en el momento de la independencia y construcción de los nuevos estados latinoamericanos y la aparición del fenómeno de la emergencia (el regreso a/de las culturas como contraposición a la pretensión de universalización y unificación de la globalización neoliberal constituyen claves a partir de las cuales el autor sostiene la esperanza latinoamericana.

    The ground array of the Pierre Auger Observatory will consist of 1600 water Cherenkov detectors, deployed over 3000 km 2 . The remoteness and large number of detectors required a simple, automatic remote calibration procedure. The primary physics calibration is based on the average charge deposited by a vertical and central throughgoing muon, determined with good precision at the detector via a novel rate-based technique and later with higher precision via charge histograms. This value is named the vertical-equivalent muon (VEM). The VEM and the other parameters needed to maintain this calibration over the full energy range and to assess the quality of the detector are measured every minute. This allows an accurate determination of the energy deposited in each detector when an atmospheric cosmic ray shower occurs

    Hailed as one of the greatest mathematical results of the twentieth century, the recent proof of Fermat's Last Theorem by Andrew Wiles brought to public attention the enigmatic problem-solver Pierre de Fermat, who centuries ago stated his famous conjecture in a margin of a book, writing that he did not have enough room to show his "truly marvelous demonstration" Along with formulating this proposition-xn+yn=zn has no rational solution for n > 2-Fermat, an inventor of analytic geometry, also laid the foundations of differential and integral calculus, established, together with Pascal, the conceptual guidelines of the theory of probability, and created modern number theory. In one of the first full-length investigations of Fermat's life and work, Michael Sean Mahoney provides rare insight into the mathematical genius of a hobbyist who never sought to publish his work, yet who ranked with his contemporaries Pascal and Descartes in shaping the course of modern mathematics.

    2014-12-01

    The Pierre Auger Observatory detects the atmospheric showers induced by cosmic rays of ultra-high energy (UHE). It is the first one to use the hybrid technique. A set of telescopes observes the fluorescence of the nitrogen molecules on clear moonless nights, giving access to the longitudinal profile of the shower. These telescopes surround a giant array of 1600 water Cherenkov tanks (covering more than 3000 km{sup 2}), which works continuously and samples the particles reaching the ground (mainly muons, photons and electrons/positrons); the light produced within the water is recorded into FADC (Fast Analog to Digital Convertes) traces. A subsample of hybrid events provides a cross calibration of the two components. We describe the structure of the Cherenkov detectors, their sensitivity to different particles and the information they can give on the direction of origin, the energy and the nature of the primary UHE object; we discuss also their discrimination power for rare events (UHE photons or neutrinos). To cope with the variability of weather conditions and the limitations of the communication system, the procedures for trigger and real time calibration have been shared between local processors and a central acquisition system. The overall system has been working almost continuously for 10 years, while being progressively completed and increased by the creation of a dense “infill” subarray. - Highlights: • The water Cherenkov technique is used in the Surface Detector of the Pierre Auger Observatory. • Cross-calibrated with the Fluorescence Detector, it provides a measurement of the primary energy. • The spectrum of the UHE cosmic rays exhibits clearly an “ankle” and a cutoff. • The muon observed muon content of the atmospheric showers is larger than expected from the models. • Stringent limits on the flux of UHE neutrinos and photons are obtained.

Muchos de los críticos y directores de teatro se resisten todavía a entender la obra —especialmente la experiencia de los amantes en el bosque— en otro sentido que no sea asumir el error aristotélico que sólo se subsana cuando los personajes aceptan finalmente la estructura social establecida. Proponemos que El Sueño de una noche de verano es una obra fundamentalmente erótica y que, a través de un lenguaje ambiguo y simbólico, Shakespeare aboga por la libertad sexual.ABSTRACT: Taking as a starting point the sources of Shakespeare in comedy and bearing in mind the most significant XXth Century contributions to the study of this comedy, this essay attempts to bring forward a new approach (endorsed by some critics to A midsummer night's dream. Many critics and theatre directors still refuse to fully comprehend the play —in particular the experience of the lovers in the wood—, making the mistake of imposing an aristotelian pattern in which the characters fully accept the established social structure. This essay asserts that A midsummer night's dream is fundamentally an erotic work and that, through the medium of an ambiguous and symbolic language, Shakespeare is advocating sexual liberty.

    2017-06-01

    In the present work we report the principal motivation and reasons for the new stage of the Pierre Auger Observatory, AugerPrime. This upgrade has as its principal goal to clarify the origin of the highest energy cosmic rays through improvement in studies of the mass composition. To accomplished this goal, AugerPrime will use air shower universality, which states that extensive air showers can be completely described by three parameters: the primary energy E 0, the atmospheric shower depth of maximum X max, and the number of muons, Nμ . The Auger Collaboration has planned to complement its surface array (SD), based on water-Cherenkov detectors (WCD) with scintillator detectors, calls SSD (Scintillator Surface Detector). These will be placed at the top of each WCD station. The SSD will allow a shower to shower analysis, instead of the statistical analysis that the Observatory has previously done, to determine the mass composition of the primary particle by the electromagnetic to muonic ratio.

    Full Text Available This paper aims to highlight some interesting convergences between the theory of the meaning-construction of the literary text proposed by Iser in The Act of Reading and Pierre Hadot’s work on the hermeneutics of the text in ancient philosophy. As we know, Hadot interprets the specificities of the ancient philosophical text as functional to guide the mind of the reader in a path that does not only have a cognitive purpose, but rather a spiritual one. The concept of «spiritual excercise», central to Hadot’s work, presents similarities ­– that are potentially very productive – to the model of the use of the literary text in Iser. Moreover, it is apt to show the extraordinary theoretical importance of a series of details, which are seemingly quite technical. In particular, a dialogue between the two approaches of Iser and Hadot allows posing in a new way a question that literary theory typically marginalizes: that of the pragmatics of the literary text.

    This paper discusses the correlation recently reported by the Pierre Auger Observatory (PAO) of the arrival directions of the highest energy cosmic rays with active galactic nuclei (AGN) located within 75 Mpc. It is argued that these correlating AGN do not have the power required to be the sources of those particles. It is further argued that the current PAO data disfavors giant radio-galaxies (both Fanaroff-Riley type I and II) as sources of ultra-high energy cosmic rays. The reported correlation with AGN should thus be understood as follows: the AGN trace the distribution of the local large scale structure, in which the actual sources of ultrahigh energy cosmic rays camouflage. The most promising theoretical candidates for these sources are then gamma-ray bursts and magnetars. One important consequence of the above is that one will not detect counterparts in gamma-rays, neutrinos or gravitational waves to the sources of these observed ultrahigh energy cosmic rays, since the cosmic rays are delayed by extragalactic magnetic fields on timescales approx10{sup 4}-10{sup 5} yrs much larger than the emission timescale of these sources.

The reported correlation with AGN should thus be understood as follows: the AGN trace the distribution of the local large scale structure, in which the actual sources of ultrahigh energy cosmic rays camouflage. The most promising theoretical candidates for these sources are then gamma-ray bursts and magnetars. One important consequence of the above is that one will not detect counterparts in gamma-rays, neutrinos or gravitational waves to the sources of these observed ultrahigh energy cosmic rays, since the cosmic rays are delayed by extragalactic magnetic fields on timescales ∼10 4 -10 5 yrs much larger than the emission timescale of these sources.

  8. Le Corbusier, Pierre Chareau and two masterpieces of modern architecture

    Directory of Open Access Journals (Sweden)

    2015-06-01

    Full Text Available Le Corbusier and Pierre Chareau are famously responsible for two projects considered iconic of modern architecture: Villa Savoye and Maison de Verre. Both are coeval and commissioned by clients with the same socioeconomic profile – the French haute bourgeoisie –, and with similar needs. Villa Savoye is a single family home, while Maison de Verre houses both residential and medical clinic functions in the same building structure. However, this difference does not interfere in our intended analysis. By comparing the client-architect relationships in both projects – Le Corbusier/Savoye and Chareau/Dalsace – we raise  questions regarding the professional behavior that modern architects have arrogated to themselves: to revolutionize customs and practices. The projects are modern and diverse responses to similar requests. In both cases, the role of women is indicative of their influence in that particular historical context as opinion setters. The house is the locus of the female dominium, and as such expresses women’s tastes and habits.

    In the frame of ANSICHT the methodology for the demonstration of safe enclosure for high-level heat generating radioactive wastes is described. The report is based on the safety requirements for final repository concepts and shows a first backfilling and sealing concept that was developed for the final repository site model SUeD. The final repository model SUeD is based on a horizontal line storage concept, the Gorleben (VSG) and ERATO container concept and the mine layout were adopted and adapted to the given conditions. The backfill and sealing concept includes migration barriers, line closures and shaft closures in the frame of a redundant and diverse enclosure system. For all technical and geotechnical barrier components the long-term functional requirements were defined. The backfilling concept of underground cavities considers the variety of possible cavities in the line and infrastructure areas.

    Full Text Available RESUMEN Existen numerosos factores biológicos, psicológicos y sociales con impacto más o menos prominente en la salud mental de las personas adultas mayores. Aparte de componentes derivados de los procesos normales de envejecimiento o de la coocurrencia de enfermedades médicas diversas, eventos como la muerte de un ser querido, la jubilación o la discapacidad, contribuyen significativamente a una variedad de problemas mentales o emocionales en esta fase del ciclo vital. Los problemas más frecuentes afectan las esferas neurocognitiva, afectiva y onírica. Los trastornos neurocognitivos mayores reducen el rendimiento general del paciente y generan con ello exigentes necesidades de dependencia y cuidado cercano. Los trastornos afectivos pueden acentuarse por falta de apoyo familiar y disminución marcada de interacciones sociales que pueden dar lugar a un significativo aislamiento con conducta suicida resultante. La mayor frecuencia de trastornos del sueño como insomnio, somnolencia diurna y trastornos específicos como apnea obstructiva alteran significativamente la calidad de vida de esta población.

    Full Text Available En 1932, los restos de las primeras experiencias sexuales del niño están conectados con marcas dolorosas de angustia, prohibición, desengaño, castigo. Dolor y displacer han dejado de ser advertencias para volverse, ellos mismos, metas. Con Más allá surge un Icc no-todo reprimido y se cierra la brecha entre los restos ópticos y auditivos de entonces. Vía sueño se produce la activación de los restos de lo-visto y de lo-oído, del tesoro de palabras de la lengua-materna, es decir, de la "herencia", que sólo se inscribe, en momentos privilegiados de un análisis, porque se adquiere contingentemente: una marca que ya no es para todos.In 1932, the aftermath of a child's first sexual experiences leaves painful scars of angst, repression, deception and guilt. Pain and displeasure had ceased to be warnings to become goals in themselves. With "Beyond the Pleasure Principle" a not-so-repressed unconscious mind emerges and closes the gap between the audiovisual memories from beforehand. Through dreams it is possible to activate these audiovisual memories, the treasure of the mother tongue, or "heritage", which is only registered in privileged moments in analysis, because it is acquired contingently: a mark that is not meant for all.

    The mass composition of ultra-high energy cosmic rays is a critical issue to understand their origin and nature. The Pierre Auger Observatory is a hybrid instrument which provides a powerful environment for the determination of the primary mass. The Surface Detector of the Pierre Auger Observatory alone allows the study of several shower parameters with high discriminating power between primary elements. Novel analysis techniques using different features of signals in the Cherenkov stations are discussed. These are the signal risetime, the azimuthal time asymmetry and the muon density of the showers.

    We describe a new method of identifying night-time clouds over the Pierre Auger Observatory using infrared data from the Imager instruments on the GOES-12 and GOES-13 satellites. We compare cloud identifications resulting from our method to those obtained by the Central Laser Facility of the Auger Observatory. Using our new method we can now develop cloud probability maps for the 3000 km^2 of the Pierre Auger Observatory twice per hour with a spatial resolution of ~2.4 km by ~5.5 km. Our method could also be applied to monitor cloud cover for other ground-based observatories and for space-based observatories.

    Endotracheal intubation in infants with the Pierre Robin syndrome may sometimes be impossible to accomplish by conventional means. To aid difficult tracheal intubation many different techniques have been described. We present a case, in which we successfully intubated a small-for-date newborn boy...... with the Pierre Robin syndrome by using a modified laryngeal mask airway (no. 1) as a guide for the endotracheal tube. The technique is easy to perform, less traumatic and less time-consuming than multiple attempts at laryngoscopy or blind tracheal intubation....

    The Pierre Auger Observatory is intended to the ultra high energy cosmic rays study. This study is realized through the particles showers coming from the interaction between the cosmic rays and the atmosphere. The ground detection of these showers requires a comprehensive understanding of the detectors. Several test tanks have been elaborated for this purpose, especially the Orsay one. The first chapter is dedicated to the presentation of the cosmic rays and of the Pierre Auger Observatory. The second one describes the detectors used for the Observatory surface array. The Orsay test tank is then presented and detailed. We study the results we have got with the Orsay test tank in the fourth chapter and compare these results with those of the Observatory detectors in the fifth chapter. The sixth chapter is dedicated to the validation of the results set through the simulation (GEANT4 software). Finally, the first detected particles showers are presented in the seventh chapter. The data acquisition has begun this year. The construction will be finished by end of 2005. From this moment, The Pierre Auger Observatory will allow us to contribute to solving the cosmic rays puzzle. (author)

    Full Text Available Se describe el síndrome de apnea del sueño (SAS abarcando los aspectos históricos, signos y síntomas, las diversas modalidades (apneas obstructiva, central y mixta, complicaciones, principalmente cardiovasculares y cerebrovasculares y formas de tratamiento. Se hace énfasis en la ayuda diagnóstica del polisomnograma que ha permitido definir como SAS síntomas antes considerados inespecíficos y cuantificar su gravedad. Se describen las diversas medidas terapéuticas, locales y generales, recalcando los beneficios que se obtienen con la aplicación de los aparatos de respiración a presión positiva. Estos permiten tratamientos no invasivos que hacen desaparecer la totalidad de los síntomas y evitan los riesgos incrementados de trastornos cardiovasculares y accidentes laborales o de tránsito. Este grave síndrome afecta a un grupo grande de población por lo que su importancia es indudable.

    Different aspects of the sleep apnea síndrome (SAS are described, including history, clinical manifestations, clinical forms (obstructive, central and mixed, cardiovascular, cerebrovascular and other complications and treatment. With the use of the polysomnogram it has been possible to define non-specific symptoms as due to SAS and to quantitate their seriousness. Different therapeutic approaches are described, both local and systemic, with emphasis on the benefits obtained from the use of positive pressure breathing machines which control every manifestation of the syndrome and avoid the increased cardiovascular risks aswell as work and traffic accidents. This syndrome is important in terms of frequency and of increased death risk.

    We describe the method devised to reconstruct inclined cosmic-ray air showers with zenith angles greater than 60° detected with the surface array of the Pierre Auger Observatory. The measured signals at the ground level are fitted to muon density distributions predicted with atmospheric cascade models to obtain the relative shower size as an overall normalization parameter. The method is evaluated using simulated showers to test its performance. The energy of the cosmic rays is calibrated using a sub-sample of events reconstructed with both the fluorescence and surface array techniques. The reconstruction method described here provides the basis of complementary analyses including an independent measurement of the energy spectrum of ultra-high energy cosmic rays using very inclined events collected by the Pierre Auger Observatory.

    Abstract The Pierre Auger Observatory is a detector for ultra-high energy cosmic rays. It consists of a surface array to measure secondary particles at ground level and a fluorescence detector to measure the development of air showers in the atmosphere above the array. The ?hybrid? detection mode combines the information from the two subsystems. We describe the determination of the hybrid exposure for events observed by the fluorescence telescopes in coincidence with at least one w...

Such a correlation measurement is a unique feature of a hybrid air-shower observatory with sensitivity to both the electromagnetic and muonic components. It allows an accurate determination of the spread of prima...

    Full Text Available The Pierre Auger Observatory, located in Argentina, provides an unprecedented integrated aperture in the search for primary photons with energy above 1017 eV over a large portion of the southern sky. Such photons can be detected in principle via the air showers they initiate at such energies, using the complement of Auger Observatory detectors. We discuss the results obtained in diffuse and directional searches for primary photons in the EeV energy range.

  20. Measurement of in-situ hydraulic conductivity in the Cretaceous Pierre Shale

    International Nuclear Information System (INIS)

    Neuzil, C.E.; Bredehoeft, J.D.

    1981-01-01

    A recent study of the hydrology of the Cretaceous Pierre Shale utilized three techniques for measuring the hydraulic conductivity of tight materials. Regional hydraulic conductivity was obtained from a hydrodynamic model analysis of the aquifer-aquitard system which includes the Pierre Shale. Laboratory values were obtained from consolidation tests on core samples. In-situ values of hydraulic conductivity were obtained by using a borehole slug test designed specifically for tight formations. The test is conducted by isolating a portion of the borehole with one or two packers, abruptly pressurizing the shut-in portion, and recording the pressure decay with time. The test utilizes the analytical solution for pressure decay as water flows into the surrounding formation. Consistent results were obtained using the test on three successively smaller portions of a borehole in the Pierre Shale. The in-situ tests and laboratory tests yielded comparable values; the regional hydraulic conductivity was two to three orders of magnitude larger. This suggests that the lower values represent intergranular hydraulic conductivity of the intact shale and the regional values represent secondary permeability due to fractures. Calculations based on fracture flow theory demonstrate that small fractures could account for the observed differences

    Full Text Available El objetivo del estudio fue describir las dificultades del sueño en estudiantes de Medicina de primer año de una institución pública en la Ciudad de México, en relación con algunos síntomas psicológicos. Se realizó un estudio transversal en 572 alumnos de primer año de Medicina, quienes fueron evaluados mediante la Symptom Check List-90 (SCL-90. Un 3.5% de los estudiantes manifestó tener muchas dificultades para conciliar el sueño, 6.3% para mantenerlo y 11.4% despertaban muy temprano. Las dificultades del sueño se asociaron en forma significativa con todas las dimensiones de psicopatología. Sus mejores predictores fueron la ansiedad, la hostilidad y la sensibilidad interpersonal. Se concluye que los síntomas asociados a tensión, enojo, preocupación, hiperactivación cognitiva e hipervigilancia son los mejores predictores para las dificultades del sueño en esta población.

Un ejemplo preciso del déficit de calidad en los datos lo constituyen las series meteorológicas diarias en las que predominan faltantes. Para hacer frente a esta situación y poder utilizar los modelos de cultivo se elaboró un software para llenar espacios vacíos en series climáticas diarias, basada en una cadena de Markov de orden dosy dos estados. La herramienta llamada SueMulador, se probó y validó con éxito en tres estaciones ubicadas en zonas contrastantes de la geografía colombiana. / Abstract. Currently, crop models are an useful tool for decision making; however, even though they are available and are easy to use, the information needed to use does not exist or not have sufficient quality. A specific example of the lack of quality is the daily weather series, in which there is too much missing data. To address this situation and to use crop models, we developed a software to fill gaps in daily climate series based on a Markov chain of order two and two states. The new tool, called SueMulador, was successfully tested and validated in three contrasting regions of Colombia.

Elle implique le recours à un sommeil fractionné et des périodes de repos courtes réparties sur l’ensemble du nycthémère. Ces difficultés sont évoquées pour expliquer les incidents, accidents et altérations des performances.Cette étude recense les stratégies mises en œuvre par neuf des meilleurs skippers de la spécialité pour préparer puis gérer ces contraintes au cours d’une course, puis suit un skipper durant une course autour du monde en solitaire et sans escale d’une durée de cent jours.A partir de ces observations, il a été proposé à un skipper expérimenté de tester un agenda interactif de « sommeil » afin d’apprendre à gérer de façon optimale ses périodes de repos durant une course.Ce travail met en évidence que les sujets sont conscients de l’importance de gérer leurs périodes de repos, mais mettent en œuvre peu de stratégies de préparation et de gestion du sommeil avant et durant leur course. Ils présentent une période d’adaptation à ces conditions extrêmes allant de 24 à 72 heures et rencontrent ensuite des périodes de fatigue extrême avec hallucinations. Cette fatigue a des conséquences sur la performance, mais aussi sur l’accidentologie qui apparaît nettement majorée avec un possible délai allant jusqu’à 72h après l’installation d’une dette de sommeil trop importante. Les outils de laboratoire, qui ne pourraient donner des informations intéressantes que sur la base d’une utilisation continue, sont très difficiles à mettre en œuvre ici.Dans ces circonstances, le recours à un agenda de sommeil « interactif », utilisé par le sujet pour comptabiliser et gérer la répartition et la durée de ses périodes de sommeil, semble être une solution individuelle de gestion des alternances veille sommeil.

    Aspergillosis was diagnosed at the cause of death of 158 mallards (Anas platyrhynchos) in January and February 1985 and 11 mallards in December 1985 near Pierre, SD. Isolation of Aspergillus fumigatus from carcass tissues confirmed the diagnosis. The sex ratio of mallards dead from aspergillosis in January and February 1985 was significantly different from the sex ratio in the local population at that time. The source of the fungus was not determined, but severe weather caused physiologically stressed mallards to feeds on corn stored in open piles on the ground, a likely source of the Aspergillus fungus.

    Atmospheric 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 Malargue and averaged monthly models, the utility of the GDAS data is shown.

    To improve reconstruction of cosmic ray primary mass, the Pierre Auger Observatory is upgrading its surface detectors by installing a scintillator on top of each existing water Cherenkov tank. The different responses of the coupled detectors to the components of extensive air showers facilitates estimation of the number of muons reaching Earth's surface, which is correlated with primary mass. Geant4 and the Offline framework are used to simulate the detectors' responses, construct signal traces for individual particle components, and calculate total expected signals. This enables assessment of proposed reconstruction algorithms. An overview of the simulations and selected algorithms is presented here.

    Abreu, Pedro; et al.

    2013-02-01

    To interpret the mean depth of cosmic ray air shower maximum and its dispersion, we parametrize those two observables as functions of the first two moments of the ln A distribution. We examine the goodness of this simple method through simulations of test mass distributions. The application of the parameterization to Pierre Auger Observatory data allows one to study the energy dependence of the mean ln A and of its variance under the assumption of selected hadronic interaction models. We discuss possible implications of these dependences in term of interaction models and astrophysical cosmic ray sources.

    Pierre Pomet is a Parisian, but as all great botanists, he liked travelling and bringing back sample of drugs that he was ultimately showing during his course at the Jardin des Plantes (Royal Herbs garden in Paris). Member of druggists and groceries storekeepers’ Community, he was not allowed to establish himself as an apothecary in Paris. It is as drug expert that he wrote and published in 1694 his “General History of Drugs, concerning herbs, animals and minerals, book enriched with more than 400 copper-plate engravings designed from nature : with explanations of their various names, their countries of origin, the way to differentiate them from falsified ones, and their properties, where one can see the errors coming from Ancients and modern writers ; the whole being very useful for the public”. This book was translated into English in 1712 and German in 1717. It is part of the reference books of the 17th century for pharmacy. In his introduction, Pierre Pomet explains that his goal is to avoid for drugs errors and falsifications that very frequent at that time. The book is then dedicated not only to physicians, apothecaries or students, etc., but also to all that used drugs.

    Plastic scintillator-based detectors are simple and yet powerful instruments, commonly used in particle physics experiments. These detectors are also planned to be installed at the Pierre Auger Observatory as part of the upgrade called AugerPrime. Here, a single detector module will consist of several large-sized scintillator bars. Embedded wavelength shifting fibres read out the scintillation light and are coupled to a single photo-sensitive device. We investigate the application of silicon photomultipliers (SiPMs) in this scope, which benefits from high photon detection efficiency and stability. We show the performance of a SiPM-based prototype device installed in the 2 m{sup 2} detector ASCII - an early prototype of the scintillating detector planned for AugerPrime. We focus on the electronics, the optical coupling and the in situ calibration. As ASCII has been operating with SiPMs for several months now, we also highlight first high-energy events seen in coincidence with the Surface Detector of the Pierre Auger Observatory.

    The Pierre Auger Observatory is the world's largest experiment detecting extensive air showers initiated by cosmic rays at the highest energies. An area of 3000 km{sup 2} is instrumented by 1660 water Cherenkov detector stations, and 27 fluorescence telescopes overlook the atmosphere above the surface detector array. A hybrid detection principle is achieved by utilizing information of both detectors. A major upgrade of the experiment (AugerPrime) has been decided adding a third detector type, scintillator detector stations located on the water Cherenkov tanks. Thereby, the composition sensitivity of the Pierre Auger Observatory is extended by an improved determination of the muonic shower component. Additionally, underground muon detectors (AMIGA) are deployed. The experiment has been further extended by antennas measuring the emission of radio signals from air showers (AERA). An overview about recent results and the current status of the experiment are given in this talk. Highlights are updated results, e.g. on the energy spectrum, chemical composition or proton-air cross section.

    2013-01-01

    The Pierre Auger Observatory explores the potential of radio-detection techniques to measure extensive air showers (EAS) induced by ultra-high energy cosmic rays. To study in detail the mechanisms responsible for radio emission in the MHz range, the Auger Engineering Radio Array has been installed at the Observatory. Presently consisting of 24 radio-detection stations, this number will grow to 150 units covering an area of almost 20 km 2 . Novel detection techniques based on the GHz emission from the EAS are currently being studied. AMBER (Air-shower Microwave Bremsstrahlung Experimental Radiometer) and MIDAS (Microwave Detection of Air Showers) are prototypes for a large imaging dish antenna. In EASIER (Extensive Air Shower Identification using Electron Radiometer), the microwave emission is detected by antenna horns located on each surface detector. MIDAS is a self-triggering system while AMBER and EASIER use the trigger from the Auger detectors to record the emission. The status of these radio-detection R and D efforts at the Pierre Auger Observatory will be reported

    AERA - the Auger Engineering Radio Array - is currently being set up at the southern site of the Pierre Auger Observatory. AERA will explore the potential of the radio-detection technique to cosmic ray induced air showers with respect to the next generation of large-scale surface detectors. As AERA is co-located with the low-energy enhancements of the Pierre Auger Observatory, the observation of air showers in coincidence with the Auger surface and fluorescence detector will allow to study the radio emission processes in detail and to calibrate the radio signal. Finally, the combined reconstruction of shower parameters with three independent techniques promises new insights into the nature of cosmic rays in the transition region from 10{sup 17} to 10{sup 19} eV. Besides the detection of coherent radiation in the MHz frequency range, the setups AMBER - Air-shower Microwave Bremsstrahlung Experimental Radiometer - and MIDAS - MIcrowave Detection of Air Showers - prepare to check the possibility to detect air showers due the emission of molecular bremsstrahlung in the GHz range at the Auger site. This article presents the status of the radio-detection setups and discusses their physics potential as well as experimental challenges. Special focus is laid on the first stage of AERA which is the startup to the construction of a 20 km{sup 2} radio array.

  20. Techniques for measuring aerosol attenuation using the Central Laser Facility at the Pierre Auger Observatory

    2013-04-01

    The Pierre Auger Observatory in Malargüe, Argentina, is designed to study the properties of ultra-high energy cosmic rays with energies above 10(18)eV. It is a hybrid facility that employs a Fluorescence Detector to perform nearly calorimetric measurements of Extensive Air Shower energies. To obtain reliable calorimetric information from the FD, the atmospheric conditions at the observatory need to be continuously monitored during data acquisition. In particular, light attenuation due to aerosols is an important atmospheric correction. The aerosol concentration is highly variable, so that the aerosol attenuation needs to be evaluated hourly. We use light from the Central Laser Facility, located near the center of the observatory site, having an optical signature comparable to that of the highest energy showers detected by the FD. This paper presents two procedures developed to retrieve the aerosol attenuation of fluorescence light from CLF laser shots. Cross checks between the two methods demonstrate that results from both analyses are compatible, and that the uncertainties are well understood. The measurements of the aerosol attenuation provided by the two procedures are currently used at the Pierre Auger Observatory to reconstruct air shower data.

    Full Text Available La apnea obstructiva del sueño o hipoventilación obstructiva en neonatos, es distinta que en los adultos y también lo son su presentación, etiología y tratamiento. Se considera apnea del sueño cuando se produce 1 episodio de apnea por hora de más de 10 segundos de duración, con saturación menor del 87% e incremento del CO2. Existen varias causas, pero los factores anatómicos y neurofuncionales son la base del problema respiratorio superior que produce fallos en las fuerzas que contraen y dilatan la vía aérea. La retromicrognatia como causa anatómica, puede ser aislada o sindrómica. La hipoxemia y la hipercapnia aumentan la presión negativa intratorácica del paciente con la consecuencia de daño celular sin que se pueda cuantificar la gravedad de la lesión cerebral en esta etapa neonatal. En el presente estudio, observacional descriptivo, entre los años 2000 y 2011, en una serie de 49 pacientes neonatos de la Unidad de Cuidados Intensivos del Recién Nacido del Hospital Universitario del Valle y del Centro Médico Imbanaco de la ciudad de Cali, Colombia, pretendemos evidenciar los beneficios del tratamiento precoz de los neonatos que presentan retromicrognatia y apnea obstructiva o hipoventilación obstructiva, intervenidos quirúrgicamente mediante corticotomía, colocación de distractores y elongación mandibular, logrando que la apnea obstructiva desapareciera en un tiempo no superior a una semana y que la mejoría clínica de los recién nacidos con este diagnostico fuera evidente, evitando la traqueotomía y las posibles complicaciones y secuelas por hipoxia cerebral, a la vez que disminuyó la estancia hospitalaria.

    Objetivo El objetivo de este estudio es demostrar la distinción entre engagement y trabajolismo, estudiando su relación con la calidad del sueño y el desempeño laboral. Método Un total de 447 enfermeras de 3 hospitales de Japón fueron entrevistadas mediante un cuestionario autoadministrado que incluía la escala Utrecht (UWES, Utrecht Work Engagement Scale), la Escala de Adicción al Trabajo Holandesa (DUWAS, Dutch Workaholism Scale), preguntas sobre la calidad del sueño (7 ítems) con respecto a (1) dificultad para conciliar el sueño, (2) dificultad para mantener el sueño, (3) despertar temprano por la mañana, (4) dormirse o tomar siestas durante el día, (5) somnolencia diurna excesiva en el trabajo, (6) dificultad para despertarse por la mañana, y (7) despertar cansado en la mañana, y el Cuestionario sobre Salud y Desempeño (CSD) de la Organización Mundial de la Salud. Resultados Los modelos de ecuaciones estructurales demostraron que el engagement se relaciona positivamente con la calidad del sueño y el rendimiento laboral, mientras que el trabajolismo tiene una relación negativa con la calidad del sueño y el desempeño laboral. Conclusión Los resultados indican que el engagement y el trabajolismo son conceptualmente diferentes. El primero tiene una connotación positiva, mientras que el segundo se asocia de manera negativa al bienestar (buena calidad del sueño y buen rendimiento en el trabajo). PMID:26752805

    La biologie étudie des structures ou des phénomènes sub-cellulaires. Pour cela la microscopie est la technique d'observation privilégiée. La résolution spatiale de la microscopie optique s'avère bien souvent insuffisante pour de telles observations. Les techniques plus résolvantes, comme la microscopie électronique par transmission sont souvent destructrices et d'une complexité peu adaptée aux besoins des biologistes. La microscopie par rayons X dans la fenêtre de l'eau permet l'imagerie rapide de cellules dans leur milieu naturel, nécessite peu de préparation et offre des résolutions de quelques dizaines de nanomètres. De plus, il existe un bon contraste naturel entre les structures carbonées (protéines, lipides) et l'eau. Actuellement cette technique est limitée aux centres de rayonnement synchrotron, ce qui impose une planification et des déplacements incompatibles avec les besoins de la biologie. Un tel microscope fonctionnant avec uns source de laboratoire serait d'une grande utilité. Ce document présente un état de l'art de la microscopie par rayons X dans la fenêtre de l'eau. Un cahier des charges détaillé pour un appareil de laboratoire ayant les performances optiques requises par les biologistes est présenté et confronté aux microscopes X de laboratoire déjà existants. Des solutions concernant la source et les optiques sont également discutées.

    The surface detector array of the Pierre Auger Observatory is sensitive to Earth-skimming tau neutrinos that interact in Earth's crust. Tau leptons from nu(tau) charged-current interactions can emerge and decay in the atmosphere to produce a nearly horizontal shower with a significant electromagnetic component. The data collected between 1 January 2004 and 31 August 2007 are used to place an upper limit on the diffuse flux of nu(tau) at EeV energies. Assuming an E(nu)(-2) differential energy spectrum the limit set at 90% C.L. is E(nu)(2)dN(nu)(tau)/dE(nu)<1.3 x 10(-7) GeV cm(-2) s(-1) sr(-1) in the energy range 2 x 10(17) eV< E(nu)< 2 x 10(19) eV.

    This is the second reported example of Hb Pierre--Benite (beta90 Glu-->Asp). This mutation is associated with increased oxygen affinity and polycythaemia. No instability was found and there was no charge shift detected by cellulose acetate electrophoresis at pH 8.3. The mutation was however, clearly indicated by electrospray ionization mass spectrometry (ESI MS), which showed an abnormal beta chain with a 14 Da decrease in mass. Blood volume studies documented a relative rather than a true polycythaemia and this finding has been reported in at least two other high affinity haemoglobin variants--Hb Heathrow and Hb Rahere. This finding led to delay in diagnosis because high oxygen affinity variants are conventionally considered to cause a true polycythaemia.

  17. Biographical narrative in relation to Great History : Les éblouissements by Pierre Mertens

    Directory of Open Access Journals (Sweden)

    Jerzy Lis

    2012-01-01

    Full Text Available Pierre Mertens’ novel Les éblouissements, published in 1987, is a fictionalised biography of a famous German poet Gottfried Benn, who made the biggest mistake of his life agreeing to support the National Socialist regime during several months. Mertens reconstructs the poet’s life trying to understand the reasons of his commitment, considered by the intellectuals of that time to be a betrayal. Mertens’ text is an illustration of the relationship between the individual and the historical past and, at the same time, an example of problemising the biographical factor in relation to Great History. Playing with the double signification of the word ‘éblouissement’, the novelist offers his own interpretation of the German poet’s double life.

    2008-07-01

    This study aimed to highlight, illustrate, describe, and comment on the presence of the health category in the work of Pierre Bourdieu, by underlining the themes traditionally related to the sociology of the body. After a systematic analysis of his work in the sociology of medicine and health, the article also addresses the main vehicle for his line of thought, namely Actes de la Recherche en Sciences Sociales, viewed here as the prime channel for most of the research taking Bourdieu's "genetic structuralism" as the main theoretical reference. We analyze the articles published from 1975 to 2001, from the thematic and theoretical/conceptual perspective, by comparing the changes appearing in this journal in opposition to the model previously adopted by the Revue Française de Sociologie.

  19. Measurement of the energy spectrum of cosmic rays from the Pierre Auger Observatory

    International Nuclear Information System (INIS)

    Roth, M.

    2009-01-01

    The large sample of data collected by the Pierre Auger Observatory has led to a significant improvement over previous measurements on the energy spectrum of cosmic rays. We observe a suppression of the flux at the highest energy with a significance of more than 6 standard deviations. The spectral index γ of the flux, J∝E -γ , at energies between 4x10 18 eV and 4x10 19 eV is 2.69±0.02 (stat) ±0.06 (syst), steepening to 4.2±0.4 (stat) ±0.06 (syst) at higher energies, consistent with the prediction by Greisen and by Zatsepin and Kuz'min. Observations of cosmic rays by the fluorescence detector allowed the extension of the energy spectrum to lower energies, where the efficiency of the surface detector is less then 100% and a change in the spectral index is expected.

    Full Text Available La notion de « commerce d’amour-propre » telle qu’elle a été élaborée par Pierre Nicole constitue-t-elle une sorte de préfiguration de l’utilitarisme moderne ? Il est commun de le penser. Mais c’est peut-être là faire trop peu de cas du soubassement théologique augustinien de la doctrine de Nicole. Pour analyser le problème, il convient de confronter la pensée de Nicole à celles de Pascal, de Hobbes et de saint Augustin lui-même.

    1993-01-01

    Pierre Gy's Sampling Theory and Sampling Practice, Second Edition is a concise, step-by-step guide for process variability management and methods. Updated and expanded, this new edition provides a comprehensive study of heterogeneity, covering the basic principles of sampling theory and its various applications. It presents many practical examples to allow readers to select appropriate sampling protocols and assess the validity of sampling protocols from others. The variability of dynamic process streams using variography is discussed to help bridge sampling theory with statistical process control. Many descriptions of good sampling devices, as well as descriptions of poor ones, are featured to educate readers on what to look for when purchasing sampling systems. The book uses its accessible, tutorial style to focus on professional selection and use of methods. The book will be a valuable guide for mineral processing engineers; metallurgists; geologists; miners; chemists; environmental scientists; and practit...

    2016-01-01

    The Pierre Auger Observatory is currently in an update stage denominated AugerPrime. The Observatory will have scintillator detectors on top of each of the surface stations (WCD). The main goal of AugerPrime is to improve the studies on mass composition for ultra high energy cosmic rays, for this purpose AugerPrime will use Universality. The model will parameterize the signal in four principal components, the objective is an adequate discrimination of the muonic and electromagnetic components. We are interested in the discrimination of these two components using simulations. To do that, we are working with OfflineTrunk (the official software of the Collaboration). Our work is focused on the development of some modules for analysis and study of the signal from AugerPrime. (paper)

    The surface detector array of the Pierre Auger Observatory provides information about the longitudinal development of the muonic component of extensive air showers. Using the timing information from the flash analog-to-digital converter traces of surface detectors far from the shower core, it is possible to reconstruct a muon production depth distribution. We characterize the goodness of this reconstruction for zenith angles around 60° and different energies of the primary particle. From these distributions, we define Xmaxμ as the depth along the shower axis where the production of muons reaches maximum. We explore the potentiality of Xmaxμ as a useful observable to infer the mass composition of ultrahigh-energy cosmic rays. Likewise, we assess its ability to constrain hadronic interaction models.

    Recent updates to the air shower universality reconstruction of surface detector data at the Pierre Auger Observatory have reduced the bias and improved the resolution of mass-sensitive variables: the depth of shower maximum and the relative number of muons. For better-informed studies of a possible anisotropy in the arrival direction of ultra-high-energy cosmic rays, a quantification of the power of these parameters to separate a proton-like signal from background is presented. The analysis is furthered with an outlook to the detector's overall sensitivity to a proton-like signal as well as a projection of our ability to distinguish between different astrophysical flux scenarios.

    With the Auger Engineering Radio Array (AERA) at the Pierre Auger Observatory radio emission of extensive air showers induced by ultra high energy cosmic rays is observed. Characteristics of the primary cosmic ray, e.g., arrival direction, mass or energy, can be measured this way. To produce high quality data, the detector needs to be well understood and calibrated. A useful tool for calibration campaigns is an octocopter. With it, a calibration source can be placed above the array, which makes this a very flexible method useful for different types of calibrations. Special focus is put on the position reconstruction and the position accuracy of the octocopter during the calibration flights. A new optical method using two cameras for these position reconstructions is presented. Results of a measurement campaign in spring 2015 are presented. In this campaign, the sensitivity of the AERA stations as well as timing characteristics were measured. The results of the sensitivity measurement are compared to simulations.

His writings on the state may seem to contain internal ambiguities. On the one hand, they argue for an actor-centered approach to the state while......, on the other hand, elaborating the power of the state as an institution transcending these actors. The purpose of this article is to reconstruct Bourdieu's understanding of the state in order to examine if the opposition between these two apparently opposite approaches are in as sharp contention as they first...... appear. The article starts out by discussing how Bourdieu has approached the state through his broader sociological approach and concepts. Afterwards it outlines the state formation processes lying at the foundation of the state's power. Next it focuses on his special emphasis on the actor strategies...

    The Pierre Auger Observatory combines the air shower fluorescence and surface array methods to study ultra-high energy cosmic rays. As the energy scale of the experiment is derived from calorimetric measurements by the fluorescence telescopes, their accurate calibration is of primary importance to all Auger data. We discuss a novel calibration method based on a remotely flown drone equipped with a specially designed light source that mimics a snapshot of an air shower traversing the atmosphere. Several drone measurement campaigns have been performed to study the properties of the Auger fluorescence telescopes and to derive an end-to-end calibration. We give an overview of the measurements and present the basic analysis chain as well as the first results of an independent cross-check of the Auger energy scale.

    Pierre Gy's equation is widely used in ore sampling. This equation is based in four parameters: shape factor, size distribution factor, mineralogical factor and liberation factor. The usual practice is to consider fixed values for the shape and size distribution factors. This practice does not represent well several important ores. The mineralogical factor considers only one specie of interest and the gangue, leaving out other cases such as polymetallic ores where there are more than one species of interest. A sensibility analysis to the Gy's equation factors was done and a procedure to determine specific values for them was developed and presented in this work. mean ore characteristics, associated with an insecure use of the actual procedure, were determined. finally, for a case study, the effects of using each alternative were evaluated.

    Simultaneous 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.

    We present a combined fit of a simple astrophysical model of UHECR sources to both the energy spectrum and mass composition data measured by the Pierre Auger Observatory. The fit has been performed for energies above 5 ⋅ 10{sup 18} eV, i.e. the region of the all-particle spectrum above the so-called 'ankle' feature. The astrophysical model we adopted consists of identical sources uniformly distributed in a comoving volume, where nuclei are accelerated through a rigidity-dependent mechanism. The fit results suggest sources characterized by relatively low maximum injection energies, hard spectra and heavy chemical composition. We also show that uncertainties about physical quantities relevant to UHECR propagation and shower development have a non-negligible impact on the fit results.

    Taken into account the great advantage of having a hybrid detector it has been developed a method, simulation independent, to determine the energy of the comic rays recorded by the surface detector of the Pierre Auger Observatory. The method assumes that the cosmic ray flux has the same distribution in zenith angle for all energy ranges. Therefore one can relate the calorimetric measurement of the fluorescence detector of the CR energy with a SD quantity, e.g. shower size at 1000m distance from the core, corrected for the different attenuations in the atmosphere. The method of measuring and calibrating the primary energy and the influence of reconstruction uncertainties on the energy spectrum are presented. (orig.)

The Southern Auger Observatory (Auger-South) in the province of Mendoza, Argentina, has been completed in 2008. First results on the energy spectrum, mass composition and distribution of arrival directions on the southern sky are really impressive. The planned Northern Auger Observatory in Colorado, USA, (Auger-North) will open a new window into the universe and establish charged particle astronomy to determine the origin and nature of ultra-high energy cosmic rays. These cosmic particles carry information complementary to neutrinos and photons and to gravitational waves. They also provide an extremely energetic beam for the study of particle interactions at energies that thirty times higher than those reached in terrestrial accelerators. The Auger Observatory is a hybrid detector consisting of a Surface Detector (SD) and an atmospheric Fluorescence Detector (FD). The hybrid data set obtained when both...

    Full Text Available An ambivalence toward language is present throughout the work of Pierre-Albert Jourdan. Words are associated with the closure of a grey world; they are always arriving late, after the fact; they are veils, masks, dreams detached from truth, knowledge, and immediacy. Yet, words and names hold out the possibility of hope; they can designate the presence of beauty in the world; they can mediate the encounter of self and other. The human word signifies itself through the substance of the world and the communion of beings. At the intersection of natural reality—the center of the real for Jourdan—and of language are found the garden, the earth, places of an ephemeral, haiku like presence where the natural opens itself to the human.

    2013-01-01

    With the Pierre Auger Observatory, being the largest air shower detector setup in the world, ultra-high-energy cosmic rays are studied with full trigger efficiency above E=3 x 10 18 eV. In order to achieve a more detailed understanding of cosmic ray physics at lower energies down to E∼10 17 eV, e.g. the transition from galactic to extragalactic sources and a possible change in the composition of the primary cosmic rays, the observatory is currently upgraded by the AMIGA enhancement (Auger Muons and Infill for the Ground Array). The muon counters of AMIGA, buried underground, will allow for dedicated measurements of the number of muons in air showers, thus increasing the precision in determining the type of the primary particle. Until middle of 2012, eight prototype muon counters of the AMIGA enhancement were installed at the experimental site of the Pierre Auger Observatory at Malargue, Argentina, forming one detector hexagon referred to as the pre-unitary cell (PUC). Each muon counter comprises a highly modular electronics readout system. Following the production of these systems, tests of single components as well as of the full readout electronics were carried out. In the framework of this thesis dedicated firmware, allowing for the commissioning and first data taking with the PUC, has been developed and tested. Among other features, this firmware includes a self-trigger of the muon counters as well as algorithms for the synchronization of the muon detector (MD) with the existing surface detector (SD) array. The functionality and performance of the electronics readout system with regard to this firmware has been investigated. In addition, first analyses of combined MD and SD data have been performed.

    Aerosols play an important role in radiative transfer processes involved in different fields of study. In particular, their influence is crucial in the attenuation of light at astronomical and astrophysical observatories, and has to be taken into account in light transfer models employed to reconstruct the signals. The Andean Argentinean region is increasingly being considered as a good candidate to host such facilities, as well as the ones for solar-energy resources, and an adequate knowledge of aerosols characteristics there is needed, but it is not always possible due to the vast area involved and the scarce atmospheric data at ground. The aim of this work is to find correlations between aerosol data and particle trajectories that can give an insight into the origin and behaviour of aerosols in this zone and can be employed in situations in which one does not have local aerosol measurements. For this purpose, an aerosol spectrometer and dust monitor (Grimm 1.109) was installed at the Pierre Auger Observatory of ultra-high-energy cosmic rays, to record aerosol concentrations in different size intervals, at surface level. These measurements are analysed and correlated with air mass trajectories obtained from HYSPLIT (NOAA) model calculations. High aerosol concentrations are registered predominantly when air masses have travelled mostly over continental areas, mainly from the NE direction, while low aerosol concentrations are found in correspondence with air masses coming from the Pacific Ocean, from the NW direction. Different size distribution patterns were found for the aerosols depending on their origin: marine or continental. This work shows for the first time the size distribution of aerosols registered at the Pierre Auger Observatory. The correlations found between mass and particle concentrations (total and for different size ranges) and HYSPLIT air mass trajectories, confirm that the latter can be employed as a useful tool to infer the sources, evolution

  20. The energy spectrum of cosmic rays measured with the HEAT extension at the Pierre Auger Observatory

    2013-01-01

    This thesis describes the calculation of the energy spectrum of cosmic rays, that is the absolute flux of cosmic rays as a function of energy, from data of air showers observed with the HEAT (High Elevation Auger Telescopes) extension and the fluorescence detector of the Pierre Auger Observatory. The Pierre Auger Observatory is the largest observatory for the study of cosmic rays. The Pierre Auger Observatory observes air showers, that are cascades of particles that were instigated by cosmic rays hitting the Earth's atmosphere, with two different detection concepts. The surface detector samples the secondary particles of air showers that hit the ground with an array of surface detector stations, whereas the fluorescence detector measures the energy loss profile of air showers by detecting fluorescence light, produced by the air showers when they travel through the atmosphere, with optical telescopes. The properties of the cosmic rays are not directly measurable but have to be reconstructed from the observed air shower parameters. Properties of particular interest are the type of the primary cosmic ray particle, its energy and its arrival direction. HEAT is an extension to the fluorescence detector of the Pierre Auger Observatory. It is designed to lower the energy threshold by one order of magnitude down to 10 17 eV or lower. HEAT is taking data since 2010. The calculation of the absolute flux of cosmic rays needs two ingredients: the number of detected air showers as a function of shower energy and the exposure of the detector as a function of energy. The studied air shower class are hybrid events, which are events that have been detected by a fluorescence detector and at least one surface detector station. The used air showers were observed in a time period of fifteen month starting from June 2010. A first step of the analysis is the reconstruction of air showers and cosmic ray parameters from raw data. To calculate the exposure, the uptime, that is the integral

Objetivos: Evaluar la asociación entre algunos hábitos de salud y tener dificultad en el sueño en alumnos de medicina de primer año. Diseño: Estudio transversal, descriptivo. Institución: Facultad de Medicina, Universidad Nacional Autónoma de México. Participantes: Alumnos de primer año de medicina. Intervenciones: Estudio en 572 alumnos de primer año de medicina con edad promedio de 18,6 años, 37% hombres, de una institución educativa pública de México, seleccionados a través de un muestreo no probabilístico. Se utilizó tres preguntas de la Symptom Check List (SCL90 para considerar dificultad del sueño y 18 preguntas correspondientes al apartado II del Perfil de Estrés de Nowack para evaluar los hábitos de salud. Mediante regresiones logísticas simples, se obtuvo los odds ratio (OR de los hábitos de salud con respecto a la presencia/ausencia de dificultad del sueño. Principales medidas de resultados: Hábitos de sueño. Resultados: Los hábitos como ‘alta promoción del descanso-sueño’ (OR=0,15; IC=0,04 a 0,64 y ‘alta prevención del riesgo’ (OR=0,59; IC=0,41 a 0,86 se asociaron 95%95% a la ausencia de dificultad del sueño. Conclusiones: Pese a que la ‘promoción del descanso sueño’ fue el hábito menos comunicado por los estudiantes, estuvo asociado a la ausencia de dificultad del sueño con respecto a otros hábitos de salud.

  2. Geography, (MOther Tongues and the Role of Translation in Giannina Braschi's El imperio de los sueños

    Full Text Available The Big Apple seems to be the central axis for the readerly and writerly "I" in El imperio de los sueños ( Empire of Dreams , by Giannina Braschi. Readers can easily realize that the text is not just about New York, but that it actually journeys through praise and blame, drinking and dancing, talking and perversing many other cities and landscapes. El imperio is a space of bohemia with streaks from the Latin American Quarter in Paris, the barrio chino barcelonés , the zaguanes of Borges's Buenos Aires, from colonial houses in Old San Juan; it evokes dandy places, the Madrid of the Profane Comedy , also, of course, an Empire State full of shepherds and other poetic voices. This textual geography, intertwined with socio-political maps and blueprints of different cultural systems and manners, leads to a boiling pot of literary references. In sync with its new maps of New York, Russia, Puerto Rico, Spain, and Latin America, El imperio represents Spanish as a strong and vivid character chiseled after many national and communal forms and frames of meaning; nothing along the lines of a preformulated vehicle for Braschi's narrative and/or poetic acts. The text displays an endless mix-and-match of Puerto Rican idioms—both from the Island and from the Spanish spoken in New York by Puerto Ricans—with expañolismos, argentinismos , and other renditions of Spanish. The tongue of Spain, the madre patria , thus multiplies its performative potential and expands the role of translation. In El imperio Spanish is not just a process to move meanings beyond its lettered confinements, out of its "grammatically correct" boundaries, into another—or foreign—language, but a way to show off its own capacity for otherness.

    Full Text Available The Republic of the dreams is an “Atlantic novel” and as such it develops a narrative on the trip and the memory of a family of Spanish origin in the contemporary Brazil. The work investigates the process of immigration and adjustment of a Galician patriarchal and capitalist, predestined to the social success. A consecration that will go up to his last consequences, coming back to his village, of which went out in 1913, to marry the daughter of a nobleman. Founder of a lineage hispanic-brazilian will remain caught in the profit that he itself interweaves on having taken part of the networks and the oligarchic practices that dominate in the country. Thus the authoress re-composes a statement ethnic-historical where she represents the ethnic segmentation of the condition state-nation and institutes the memory and the culture as elements of resistance.

    La República de los sueños es una “novela atlántica” y como tal desarrolla una narrativa sobre el viaje y la memoria de una familia de origen español en el Brasil contemporáneo. La obra indaga el proceso de inmigración y adaptación de un gallego patriarcal y capitalista, predestinado al éxito social. Una consagración que llevará hasta sus últimas consecuencias, retornando a su aldea, de la cual salió en 1913, para casarse con la hija de un hidalgo. Fundador de un linaje hispanobrasileño quedará atrapado en el lucro que él mismo entreteje al participar de las redes y las prácticas oligárquicas que dominan en el país. De este modo la autora recompone un relato etnohistórico donde representa la segmentación étnica del estado-nación e instituye la memoria y la cultura como elementos de resistencia.

    Full Text Available The greening of Christianity: Charles Darwin, Pierre Teilhard de Chardin and Lloyd Geering. Since the time of Charles Darwin, evolutionary biology challenged the metanarrative of Christianity which can be summarised as Fall-Redemption-Judgement. Pierre Teilhard de Chardin tried to circumvent these challenges by integrating the traditional Christian doctrines with evolutionary biology. However, he did not succeed since the Catholic Church, time and again, vetoed his theological publications. A number of Protestant theologians promoted his views but even they could not convince ordinary Christians to accept his views. These were too esoteric for Christians. Most of them were convinced that the acceptance of the theory of evolution will eventually undermine their faith. In recent years Lloyd Geering argued a case for the creation of a new narrative in which the Big Bang and the theory of evolution do play a role. He calls it the ‘Greening of Christianity’. This article discusses the metanarrative of Christianity and the challenges the theory of evolution presents before it assesses the views of Pierre Teilhard de Chardin and Lloyd Geering.

    Full Text Available Professor Elizabeth Adams St. Pierre’s work focuses on critical and poststructural theories of language and the subject and what she has called post qualitative inquiry or post inquiry. She asks what might come after conventional humanist qualitative research methodology. She’s especially interested in the new empiricisms/new materialisms as well as new research practices enabled by the ontological turn. During St. Pierre's visit to the Finnish Educational Research Association (FERA Conference in Oulu in November 2014, we had the opportunity to talk with her about post qualitative research around some questions we had sent her beforehand. We then transcribed, edited, and translated the interview, and published it in the Finnish journal Kasvatus (Education in spring 2015. In this interview St. Pierre talks in the US context, where qualitative methodology is turning—or being pushed to turn—back to positivism with normalized and formalized practices, St. Pierre encourages researchers to constantly question the prevailing truths and the traditions they have learnt too well.

    Full Text Available This paper tries to draw a new perspective on Pierre Naville’s work, essential for the consolidation of the Sociology of Labour in France but nevertheless almost unknown and frequently misunderstood in Spain. Our interpretation is based on the debates held by Naville with his collaborators about the theoretical and methodological positions adopted by this branch of studies at the very first moment of its institutionalization in the sixties. These debates can be summarized in three main lines: (1 the criticism to the reduction of the object «work» into «post, process and situation». (2 The questioning of the analytical frame which studied the evolution of «work» taking for granted the natural unity among the producer, his tool, his activity and his product, unity represented by the craftsman. (3 The criticism to the methodological procedures that eluded both the problem of time — taking only into account the single instant— and measure —ignoring the study of salary—. These three splits contribute to shift the problem of waged labour from the technical and organizational conformation of posts and processes of work and the social and institutional forms of employments and socially built job markets, to the relationships between works and work force, posts and jobs, technical and social divisions of work, considering that this relationships structure the subject’s life (times of work/leisure/recovering. Finally, we argue that this shift can be useful to outline a theoretical link between the two shores existing in current European Sociology of Labour: a Sociology based in the work situation and a Sociology based in the labour marketEste artículo traza un particular itinerario sobre la obra de Pierre Naville, autor esencial en las primeras etapas de la consolidación de la sociología del trabajo en Francia pero que, a pesar de ello, resulta aún mayormente desconocido y no siempre bien interpretado en nuestro país.

    Full Text Available In this article I offer an overview of my doctoral dissertation, which studied the social imaginary of consumerism, and the psychological subjectivity it produces, through the dream - as both a leitmotif or thematic lens, and the empirical object of research. For such I employed an interdisciplinary exploratory outlook, whose theoretical framework first discusses the symbolic imaginaries (G. Durand and their relations with the unconscious psyche, dream, imagination, and subjectivity (C. G. Jung, and then explores their relationships with consumption (Baudrillard, Bauman and its semiotic imaginaries and ideology, focusing on the concepts of consumption dreams and dream-worlds of consumption. The main research aim was to explore how night dreams represent the colonization of subjectivity by the imaginary of consumerism. The method consisted in a multiple-case study in which each night dream was taken as a case and interpreted through Jungian hermeneutics. Findings stress that night dreams can offer a deep sociocultural critique; in them the imaginary of consumption appeared as a totalizing mass ideology engendering colonization of both symbolic imaginaries and the subject and her unconscious psyche. Conclusions emphasize such colonization as an anthropological mutation - the progressive commodification and dehumanization of the subject.En este articulo describo a grandes rasgos mi tesis doctoral, que investigó el imaginario social del consumismo, y el sujeto psicológico que el mismo produce, a través del sueño - como leitmotif o lente temática y como objeto de investigación empírica.

    2015-02-01

    Full Text Available In this article the relationship which can be established between the dreamsof Anabasis in sor Juana Inés de la Cruz’s poem, Primero sueño and the novelby Sergio Fernández, Segundo sueño, is analized in a concordance where the soul during its journey through the supra lunar spheres, or in the transmutation of natural elements —rain, snow and mud—, experiences the mystery of itsencounter with the divine as a process of initiation.In the poem, the pursuit of higher knowledge is a trap; in the novel, the crossroads is found in the transgressive eroticism. These two trips of anabasis,the first and the second dream, translate the wink announcing the succession ina fall. In both cases, the excess of the soul, a tragic hero mask, melts the wingsof Icarus and conduces to the death of Phaeton, the death of the inexperienced charioteer of the divine chariot.

    Directory of Open Access Journals (Sweden)

    Robin Ann Rice Carlssohn

    2015-07-01

    Full Text Available Hasta el siglo XV, la medicina natural consideraba la melancolía cómo una enfermedad lamentable que afectaba la moralidad y el ser físico del hombre. Bajo las influencias del pensamiento neoplatónico florentino, el melancólico surgió como prototipo del genio artístico moderno. Tanto Durero, que produjo su Melancholia 1 en 1514, como Sor Juana Inés de la Cruz, que redactó el “Primer sueño” por 1685, fueron fuertemente influenciados por el humanismo italiano. La hipótesis del trabajo es que el “Primer sueño” es una ecfrasis de Melancholia 1y que las dos obras son un parteaguas por el cambio de la percepción de la melancolía. Bajo el influjo del pensamiento de Ficino, entre otros, la melancolía se convirtió en signo del genio y su deseo de desamarrarse del terreno físico para ascender a la contemplación divina.

    2010-11-01

    This issue is devoted to our colleague and friend Pierre Duclos who passed away suddenly and prematurely in Prague on 12 January this year. We want to honour his memory in the way he would have liked, by collecting fresh and original work from his area of interest. Pierre Duclos was born on 8 January 1948 in Paris. He started as an engineering student but also attended graduate courses at the Centre de Physique Théorique (CPT) in Marseille, which inspired him to change his path and pursue the professional career of a researcher. He joined the Mathematical Physics team at CPT and obtained a position at the University of Toulon, where he later became a full professor. He was never solitary; always being full of energy and a smart and sociable person, he started and maintained many international collaborations and organized numerous conferences and seminars. In the early eighties he had strong ties with the Free and Technical Universities of Berlin. From the beginning of the nineties, he collaborated with coleagues in Prague, Bucharest, Santiago de Chile, and more recently also in Aalborg and Dublin. His scientific interests were wide, with a focus on mathematical methods of quantum theory. He made important contributions to our understanding of multiple-well Schrödinger operators, geometrically-induced properties of quantum waveguides, spectra of Wannier-Stark systems, dynamics with time-periodic perturbations, and transport in mesoscopic systems, to name his most significant results. We choose for this issue the title `Spectral and transport properties of quantum systems' which cover the subjects of most papers to which his colleagues, and often coauthors, contributed. We have also included a few other papers with topics related to Pierre's work. We are glad we were able to gather a numerous collection of papers which in our view represent interesting new developments. A few of them are works which bear Pierre's signature and have been completed by his

  11. Conspiracies of immanence: Paul Tillich, Pierre Teilhard de Chardin and C.G. Jung.

    Science.gov (United States)

    Dourley, John

    2015-02-01

    Jung's psychology proffers a sustained reflection on the traditional religious question of the relation of divine transcendence to immanence. On this issue his psychology affirms a position of radical immanence in its contention that the experience of divinity is initially wholly from within. Though this position remains on the periphery of religious and theological orthodoxy Jung is not alone in holding it among moderns. Paul Tillich adopts a similar stance with his controlling symbols of the divine as 'Ground of Being' and 'Depth of Reason'. Pierre Teilhard de Chardin understands divinity as the experiential energy of evolution itself working within nature and humanity toward greater configurations of universal communion as the basis of community. All of Jung's master symbols of individuation assume such an understanding of immanence uniting individual and totality. His psychology strongly suggests and contributes to the current emergence of a new religious sensitivity based on the awareness of the intra-psychic origin of all religions. In his later writings he held out such a position as a significant alternative to genocide. © 2015, The Society of Analytical Psychology.

    Full Text Available The muon content of extensive air showers produced by ultra-high energy cosmic rays is an observable sensitive to the composition of primary particles and to the properties of hadronic interactions governing the evolution of air-shower cascades. We present different methods for estimation of the number of muons at the ground and the muon production depth. These methods use measurements of the longitudinal, lateral, and temporal distribution of particles in air showers recorded by the detectors of the Pierre Auger Observatory. The results, obtained at about 140 TeV center-of-mass energy for proton primaries, are compared to the predictions of LHC-tuned hadronic-interaction models used in simulations with different primary masses. The models exhibit a deficitin the predicted muon content. The combination of these results with other independent mass composition analyses, such as those involving the depth of shower maximum observablemax, provide additional constraints on hadronic-interaction models for energies beyond the reach of the LHC.

    Full Text Available Pongamia (Pongamia pinnata (L. Pierre is one of a potential tree species to produce biodiesel. Pongamia-based biodiesel development program is still constrained by the availability of quality and quantity seeds due to the limited of seed sources. The purpose of this research was to identify the morphological diversity of fruits, seeds and seedlings from 5 populations in Java Island. Randomized completely design and randomized block design were used to assess the difference of fruits, seeds and seedlings morphological characteristics among populations. Principal component and hierarchy cluster analysis were used to explain variation pattern among populations. The results showed that the difference of populations was significantly affected by the difference of fruits, seeds, and seedlings morphology of pongamia. Seeds from Carita population showed good quality seed indicators with moisture content of 19.31%, and germination capacity of 74.50%. Sturdiness quotient of the seedling was 10.78. Contribution of genetic factor was higher than environtment factor is relation to the differences of morphological characteristics of fruits, seeds and seedlings of pongamia. Morphological character of the five populations can be divided into 3 groups, i.e. the first group of Batukaras and Kebumen, second group of Alas Purwo and Baluran, and group 3 was Carita.

  14. THE FORTUITOUS LATITUDE OF THE PIERRE AUGER OBSERVATORY AND TELESCOPE ARRAY FOR RECONSTRUCTING THE QUADRUPOLE MOMENT

    Determining anisotropies in the arrival directions of cosmic rays at the highest energy is an important task in astrophysics. It is common and useful to partition the sky into spherical harmonics as a measure of anisotropy. The two lowest nontrivial spherical harmonics, the dipole and the quadrupole, are of particular interest, since these distributions encapsulate a dominant single source and a plane of sources, as well as offering relatively high statistics. The best experiments for the detection of ultra high energy cosmic rays currently are all ground-based, with highly nonuniform exposures on the sky resulting from the fixed experimental locations on the Earth. This nonuniform exposure increases the complexity and error in inferring anisotropies. It turns out that there is an optimal latitude for an experiment at which nonuniform exposure does not diminish the inference of the quadrupole moment. We derive the optimal latitude and find that (presumably by a fortuitous coincidence) this optimal latitude runs through the largest cosmic ray experiment, the Pierre Auger Observatory (PAO) in the Southern Hemisphere, and close to the largest cosmic ray experiment in the Northern Hemisphere, the Telescope Array (TA). Consequently, assuming a quadrupole distribution, PAO and TA can reconstruct the cosmic ray quadrupole distribution to a high precision without concern for their partial sky exposure

    Full Text Available Review of Mariette and the Science of the Connoisseur in Eighteenth-Century Europe by Kristel Smentek, Farnham: Ashgate, 2014. In her book Smentek brings back to life the rich scope of economic and scholarly activities and social ambitions employed by the art dealer and collector of European renown, Jean-Pierre Mariette (1694-1774. By concentrating on the various artistic media in which he was primarily involved, she each time singles out an aspect of Mariette’s expertise. Economic and social shrewdness in the case of printmaking, the very core of his art connoisseurship in the case of drawing, and his art-historical scholarship in the case of gem engraving. In spite of the diverse connections she here creates between artistic medium and expertise, Smentek makes abundantly clear that the scientific method of art connoisseurship was underlying the employment of all these artistic media, which favoured empirical analysis in the historical understanding of art. She thereby makes a highly convincing case of the ways in which Mariette’s practices changed the terms in which the artistic past was scrutinized. On this basis it seems only logical to further research the impact of Mariette’s practices on art-scholarly projects initiated elsewhere in Europe and the ways it contributed to the emergence of art history as a modern discipline.

  16. New electronics for the surface detectors of the Pierre Auger Observatory

    The Pierre Auger Observatory is the largest installation worldwide for the investigation of ultra-high energy cosmic rays. Air showers are detected using a hybrid technique with 27 fluorescence telescopes and 1660 water-Cherenkov detectors (WCD) distributed over about 3000 km{sup 2}. The Auger Collaboration has decided to upgrade the electronics of the WCD and complement the surface detector with scintillators (SSD). The objective is to improve the separation between the muonic and the electron/photon shower component for better mass composition determination during an extended operation period of 8–10 years. The surface detector electronics records data locally and generates time stamps based on the GPS timing. The performance of the detectors is significantly improved with a higher sampling rate, an increased dynamic range, new generation of GPS receivers, and FPGA integrated CPU power. The number of analog channels will be increased to integrate the new SSD, but the power consumption needs to stay below 10 W to be able to use the existing photovoltaic system. In this paper, the concept of the additional SSD is presented with a focus on the design and performance of the new surface detector electronics.

    AMIGA (Auger Muons and Infill for the Ground Array) is an upgrade of the Pierre Auger Observatory designed to extend its energy range of detection and to directly measure the muon content of the cosmic ray primary particle showers. The array will be formed by an infill of surface water-Cherenkov detectors associated with buried scintillation counters employed for muon counting. Each counter is composed of three scintillation modules, with a 10 m2 detection area per module. In this paper, a new generation of detectors, replacing the current multi-pixel photomultiplier tube (PMT) with silicon photo sensors (aka. SiPMs), is proposed. The selection of the new device and its front-end electronics is explained. A method to calibrate the counting system that ensures the performance of the detector is detailed. This method has the advantage of being able to be carried out in a remote place such as the one where the detectors are deployed. High efficiency results, i.e. 98% efficiency for the highest tested overvoltage, combined with a low probability of accidental counting (~2%), show a promising performance for this new system.

    We present the first hybrid measurement of the average muon number in air showers at ultrahigh energies, initiated by cosmic rays with zenith angles between 62° and 80°. The measurement is based on 174 hybrid events recorded simultaneously with the surface detector array and the fluorescence detector of the Pierre Auger Observatory. The muon number for each shower is derived by scaling a simulated reference profile of the lateral muon density distribution at the ground until it fits the data. A 1019 eV shower with a zenith angle of 67°, which arrives at the surface detector array at an altitude of 1450 m above sea level, contains on average (2.68 ±0.04 ±0.48 (sys))×107 muons with energies larger than 0.3 GeV. The logarithmic gain d ln Nμ/d ln E of muons with increasing energy between 4 ×1018 eV and 5 ×1019 eV is measured to be (1.029 ±0.024 ±0.030 (sys)) .

    Ultra high energy cosmic rays are the most energetic particles in the universe. They are measured to have energies of up to 1020 eV and occur at a rate of about once per square kilometer per century. To increase the probability of detecting one of these events, a huge detector covering a large area is needed. The Pierre Auger Collaboration build up an observatory covering 3000 square kilometers of the Pampa Amarilla close to Malargüe for this purpose. Until now, the Auger Observatory has been controlled exclusively via the local network for security and performance reasons. As local operation is associated with high travel costs, the Auger ACCESS project, started in 2005, has constructed a secure, operable and sustainable solution for remote control and monitoring. The implemented solution includes Grid technologies for secured access and infrastructure virtualization for building up a fully featured testing environment for the Auger Observatory. Measurements showed only a negligible delay for communicating with the observatory in Argentina, which allows the establishment of remote control rooms in the near future for full remote operation and remarkable cost reduction.

  20. Infusing fundamental cause theory with features of Pierre Bourdieu's theory of symbolic power.

    The theory of fundamental causes is one of the more influential attempts to provide a theoretical infrastructure for the strong associations between indicators of socioeconomic status (education, income, occupation) and health. It maintains that people of higher socioeconomic status have greater access to flexible resources such as money, knowledge, prestige, power, and beneficial social connections that they can use to reduce their risks of morbidity and mortality and minimize the consequences of disease once it occurs. However, several key aspects of the theory remain underspecified, compromising its ability to provide truly compelling explanations for socioeconomic health inequalities. In particular, socioeconomic status is an assembly of indicators that do not necessarily cohere in a straightforward way, the flexible resources that disproportionately accrue to higher status people are not clearly defined, and the distinction between socioeconomic status and resources is ambiguous. I attempt to address these definitional issues by infusing fundamental cause theory with features of a well-known theory of socioeconomic stratification in the sociological literature-Pierre Bourdieu's theory of symbolic power.

    Full Text Available To evaluate a comprehensive scoring system which combines clinical manifestations of Pierre Robin Sequence (PRS including severity of breathing difficulties, body weight and preoperative Cormack-Lehane grade, for its correlation with perioperative PRS airway management decision.Forty PRS children were retrospectively recruited after surgery. Specialists examined all subjects and scored for clinical manifestations (1´ - 4´, weight gain (1´- 4´, dyspnea scores (1´- 4´, and Cormack-Lehane grade (1´- 4´. The correlation of the integrated scores and the necessity of endotracheal intubation or laryngeal mask application were analyzed. In addition, the score correlation with postoperative dyspnea and/or low pulse oxygen saturation (SPO2 levels after extubation was determined.In our study every individual patient had a score from 0´ to 16´, while the higher in the numbers represented higher risk of breathing difficulty. All patients with comprehensive scores 13 points required a laryngeal mask assisted airway management and were considered to have difficult airways. Dyspnea after extubation and postoperative low SPO2 occurred among patients who scored over 10 points.In PRS patients, preoperative weight gaining status and severity of dyspnea in combination with Cormack-Lehane classification provide a scoring system that could help to optimize airway management decisions such as endotracheal intubation or laryngeal mask airway placement and has the potential to predict postoperative dyspnea or low SPO2 levels.

    Cosmic radiations of ultra high energy (RCUHE, beyond 10 18 eV) are difficult to study because of their low flux on the earth surface: about 1 photon per year and per km 2 . The observatory Pierre Auger proposes to study RCUHE by designing 2 sites of 3000 km 2 (one in each hemisphere) allowing the observation of the shower initiated by cosmic radiation by using 4 fluorescence telescopes and a network of 1600 Cherenkov detectors. The identification of the primary particle is a very delicate point, the detection of neutrino or photon at these energies would bring valuable information for the understanding of potential sources of RCUHE. The first part of this work presents the project and its assets to perform its task. The second part is dedicated to the description of the Cherenkov detectors, of the trigger system, and of the centralized data acquisition system. The last part present the prototype installation that is under construction at Macargue in Argentina. (A.C.)

  3. The sociologist and the state. An assessment of Pierre Bourdieu's sociology.

    2015-06-01

    This paper provides an assessment of Pierre Bourdieu's sociology based on a reading of his posthumously published lectures on the state in Sur l'État. It argues that the state was a foundational element in Bourdieu's rendition of the symbolic order of everyday life. As such, the state becomes equally pivotal in Bourdieu's sociology, the applicability of which rests on the existence of the state, which stabilizes the social fields and their symbolic action that constitute the object of sociology. The state, which Bourdieu considers a 'meta'-ordering principle in social life, ensures that sociology has a well-ordered object of study, vis-à-vis which it can posit itself as 'meta-meta'. The state thus functions as an epistemic guarantee in Bourdieu's sociology. A critical analysis of Bourdieu's sociology of the state offers the chance of a more fundamental overall assessment of Bourdieu's conception of sociology that has relevance for any critical sociological perspective that rests on the assumption of a meta-social entity, such as the state in Bourdieu's work, as a final ordering instance. © London School of Economics and Political Science 2015.

    While docking at the QIT facility at Havre St. Pierre, Quebec, on March 23, 1999, the cargo ship M/V Gordon C. Leitch collided with the dock, ruptured a fuel tank, and spilled 49 metric tons of light bunker oil (IFO-180) in the Gulf of St. Lawrence. The situation seemed under control at the beginning since the ice cover contained the migration of oil, but it quickly degenerated when the whole picture became clear. The spill occurred in a remote location where wildlife is abundant and diversified. The economy was largely dependant on ecotourism and several environmental and social factors had to be considered when devising the clean up procedure. Oil was found on 120 km of shoreline in the vicinity of the Mingan Archipelago National Park, a wildlife sanctuary protected by the government of Canada. There were oil-covered birds, a native hunting ground, several fishing zones and the National Park. The spill was cleaned up in two months. The authors described the different factors to be considered and the appropriateness and effectiveness of the Regional Environmental Emergency Team in setting priorities and choosing the best course of action to deal with each set of circumstances. 1 tab., 2 figs.

    This study looks to correlate telemetry data gathered on patients with Pierre Robin Sequence (PRS) with sleep study data. Strong correlation might allow obstructive sleep apnea (OSA) to be reasonably predicted without the need for sleep study. Charts from forty-six infants with PRS who presented to our children's hospital between 2005 and 2015 and received a polysomnogram (PSG) prior to surgical intervention were retrospectively reviewed. Correlations and scatterplots were used to compare average daily oxygen nadir, overall oxygen nadir, and average number of daily desaturations from telemetry data with apnea-hypopnea index (AHI) and oxygen nadir on sleep study. Results were also categorized into groups of AHI ≥ or sleep study data. Patients with O2 nadir below 80% on telemetry were not more likely to have an O2 nadir below 80% on sleep study. Patients with an average O2 nadir below 80% did show some correlation with having an AHI greater than 10 on sleep study but this relationship did not reach significance. Of 22 patients who did not have any desaturations on telemetry below 80%, 16 (73%) had an AHI >10 on sleep study. In the workup of infants with PRS, the index of suspicion is high for OSA. In our series, telemetry data was not useful in ruling out severe OSA. Thus our data do not support forgoing sleep study in patients with PRS and concern for OSA despite normal telemetry patterns.

  9. Mass production of extensive air showers for the Pierre Auger Collaboration using Grid Technology

    2012-06-01

    When ultra-high energy cosmic rays enter the atmosphere they interact producing extensive air showers (EAS) which are the objects studied by the Pierre Auger Observatory. The number of particles involved in an EAS at these energies is of the order of billions and the generation of a single simulated EAS requires many hours of computing time with current processors. In addition, the storage space consumed by the output of one simulated EAS is very high. Therefore we have to make use of Grid resources to be able to generate sufficient quantities of showers for our physics studies in reasonable time periods. We have developed a set of highly automated scripts written in common software scripting languages in order to deal with the high number of jobs which we have to submit regularly to the Grid. In spite of the low number of sites supporting our Virtual Organization (VO) we have reached the top spot on CPU consumption among non LHC (Large Hadron Collider) VOs within EGI (European Grid Infrastructure).

  11. Dedication Pierre Binétruy (1955 - 2017): A scientific biography

    International Nuclear Information System (INIS)

    2017-01-01

    Pierre Binétruy, born in 1955, obtained his “state doctorate” in 1980 under the direction of Mary K. Gaillard, with a thesis on “Theoretical aspects and phenomenology of gauge theories”. From 1979 to 1986, he held several positions as postdoctoral fellow at CERN and in the United States (University of California at Berkeley, University of Florida, University of Chicago). In 1986, he was recruited as a CNRS researcher at the LAPP, Annecy-le-Vieux and 4 years later as a professor at the University of Paris XI in the Laboratory of Theoretical Physics. In 2003, he was named professor at the University Paris Diderot. His main interests evolved from high-energy particle physics (notably supersymmetry) to cosmology and gravitation, and he worked in particular on the interface between the study of the primordial Universe and the theories of fundamental interactions. Recent interests included inflation models, dark energy, and the cosmic gravitational wave background. During a prolific career, he has published seminal papers that have received more than 1000 citations each. For his research he has received several awards, such as the Thibaud Prize, the Paul Langevin Award from the SFP, and was named Berkeley Miller Professor in 1999. He was arguably one of the most brilliant theorists of his time. His memory will also remain because, to paraphrase André Malraux, he combined “spirit and courage”. He knew that it is not sufficient to seek scientific truth but that one must also have the courage to organize the community for the scientific goals that this imposes and to also fight within the institutions to defend them. Our more senior colleagues will remember the extraordinary intellectual atmosphere that animated the Supersymmetry Research Group (a CNRS “groupement de recherche”), which he initiated and directed from 1997 to 2004, transforming it into an unprecedented crossroads of experimenters and theorists, of new ideas both from theory and from

This is an interpretation which permits to face such matters from inside a fully Surrealist point of view, rather than from outside it (and a little more metaphysically as Juan Larrea pretended to, thus allowing to put the basis for a possible comparison between him and his friend Mabille, who both never failed to influence each other.Keywords: Monism; Surrealism; Materialism; Engels; Marxism.ITQuesto testo è un breve commento dell’articolo Del nuevo mundo di Pierre Mabille, apparso in Messico nel 1943 e che qui forniamo nella nostra traduzione, probabilmente la prima in assoluto in Italia di uno scritto di quest’importante surrealista, poco studiato anche dalla critica francese.Nei limiti dello spazio disponibile e delle tematiche del testo in questione abbiamo preferito esporre le rela¬zioni implicite – eppure così evidenti – del pensiero di Mabille

    The workup of patients with Pierre Robin sequence (PRS) consists of a physical examination, O 2 saturation, and polysomnography to determine the severity of respiratory obstruction and need for surgery. We suggest that capillary blood gas (CBG) may be a better physiologic representation of airway obstruction and should be routinely used in the management of patients with PRS. This is a multicenter study based on a retrospective review of medical records. The study was performed at tertiary care centers. Patients with PRS <1 year old underwent mandibular distraction osteogenesis. Using successful treatment outcome as a reference standard, receiver operating characteristic (ROC) curve was used to determine the accuracy of the diagnostic test and values for the best sensitivity and specificity to determine the need for surgical intervention. Of 73 patients, 48 had sporadic PRS, 23 had syndromes, 2 had micrognathia, not otherwise specified. Mandibular distraction osteogenesis was performed in 62 patients at a mean age of 39 days. The mean initial Apnea-Hypopnea Index (AHI) in nonsurgical versus surgical groups was 10 versus 31 ( P = .063), pH 7.41 versus 7.34 ( P = .003), pCO 2 43 versus 56 ( P < .001), and HCO 3 27 versus 30 ( P = .022). The ROC curve showed that pCO 2 of 49.5 has the best specificity (100%) and sensitivity (72.6%) profile in terms of need for definitive airway. A simple CBG heel stick may better predict the physiologic effects of obstructive apnea; therefore, it should be added to the algorithm of PRS workup.

  14. Approaches to the study of religion in Pierre Bourdieu’s social theory

    Full Text Available The article considers Pierre Bourdieu’s approaches to the study of religion: the author analyzes basic concepts of Bourdieu’s sociology of religion and identifies religious spheres and traditions to which his ideas can be applied. The methods developed by Bourdieu, despite their limitations, successfully work in the contemporary studies. Bourdieu’s theory of religion became the starting point for some new approaches, in particular, for the study of ritual practices. His concept of religious habitus allows to analyze the mechanisms by which the religion generates certain practices, conventions, life styles, meanings and values according to its doctrine and experience. Representatives of one denomination usually not only follow the same rules and rituals, but also have a similar taste, life style and perception of religious leaders. The habitus embodies traditions and history of a denomination; it is a means of keeping up practices and their transfer to next generations. At the same time, Bourdieu’s approaches to the study of religion have some weaknesses: his theoretical model is too dependent on the French context and describes mainly the catholic church; his techniques aim to analyze the relationship between the state and the dominant church with its hierarchical structure. Another limitation of Bourdieu’s approach is that he attributes economic logic of supply and demand to the religious activities, and defines religion as determined exclusively to legalize and reproduce unequal and unjust social order. Bourdieu believed that the church was always linked with the mechanisms of social domination, exercise of power and consecration of the ruling classes’ privileges, i.e. with the merits of maintaining social order and legitimizing the power. Thus, Bourdieu credits the producers of religious capital with too much power and capabilities, which they do not really have. In Bourdieu’s theory, religion is an instrument of the struggle

    In areas of the Estación Central de Investigaciones de Café y Cacao located in La Mandarina, Tercer Frente municipality, Santiago de Cuba province, and La Alcarraza, municipality Sagua de Tánamo, Holguín province, the biomass production of Coffea canephora Pierre ex Froehner var. Robusta was assessed from planting until the fourth year in both locations and after pruning until the fourth year in Alcarraza. The coffee trees were planted at 3 x 1,5 m in Cambisol under Samanea saman Jerr shade in the first town and Leucaena leucocephala Lam de Wit in the second. The biomass was separated into: leaves, branches, stems, fruits and roots. From 24 months and one year after pruning, leaflitter was collected monthly. For the study of the root system soil blocks of 25 x 25 x 25 cm were extracted, in an area formed by 1,5 m (distance to the street) and 0,75 m (between plants), centered relative to the coffee plant and up to a meter deep. The extracted soil represented ¼ of the volume occupied by the plant. The dry mass of each organ was determined. Dry matter production reached values of 25 t dry mass ha-1 regardless of the stage of the plantation. Until the fourth year the root system dominated the biomass, followed by the leaves and then the stems. The participation of the fruits in the biomass increased in the crop stage and when concluding the experiment the coffees had dedicated for its formation among the 16-20 % of the total dry mass, independently of the development cycle.

    The overall picture of the highest energy particles produced in the Universe is changing because of measurements made with the Pierre Auger Observatory. Composition studies of cosmic rays point towards an unexpected mixed composition of intermediate mass nuclei, more isotropic than anticipated, which is reshaping the future of the field and underlining the priority to understand composition at the highest energies. The Observatory is competitive in the search for neutrinos of all flavors above about 100 PeV by looking for very inclined showers produced deep in the atmosphere by neutrinos interacting either in the atmosphere or in the Earth's crust. It covers a large field of view between -85° and 60° declination in equatorial coordinates. Neutrinos are expected because of the existence of ultra high energy cosmic rays. They provide valuable complementary information, their fluxes being sensitive to the primary cosmic ray masses and their directions reflecting the source positions. We report the results of the neutrino search providing competitive bounds to neutrino production and strong constraints to a number of production models including cosmogenic neutrinos due to ultra high energy protons. We also report on two recent contributions of the Observatory to multimessenger studies by searching for correlations of neutrinos both with cosmic rays and with gravitational waves. The correlations of the directions of the highest energy astrophysical neutrinos discovered with IceCube with the highest energy cosmic rays detected with the Auger Observatory and the Telescope Array revealed an excess that is not statistically significant and is being monitored. The targeted search for neutrinos correlated with the discovery of the gravitational wave events GW150914 and GW151226 with advanced LIGO has led to the first bounds on the energy emitted by black hole mergers in Ultra-High Energy Neutrinos.

    This thesis is focused in the development of analysis methods of data measured by the Pierre Auger Observatory's surface array.The Auger Observatory is being built in Malargue, Mendoza and its objective is to detect ultra high energy cosmic rays (E > 10 1 8eV) in order to understand their origin, propagation and to be able to identify their sources.Chapter 1 is a summary of current cosmic rays' theory.It includes details about the energy spectrum of cosmic rays, acceleration sites, forms of acceleration, chemical composition of cosmic rays, the GZK cutoff, magnetic lensing and experiments.Following in Chapter 2 deflection as a function of energy, using the equation of small deflections to first or second order, is analyzed, and the energy range where is approximation is valid is determined.Then, the case of multiple images, which appear when a caustic crosses the position of a source, is studied.Two simulations of cosmic rays from point sources and propagating through a realistic model of the galactic magnetic field were used.Principal and secondary images were analyzed in order to extract information concerning their sources and the magnetic fields they passed through.In Chapter 3 the Minimal Spanning Tree method (MST) used for the detection of filamentary structures is studied.This method was adapted to the analysis of cosmic rays' arrival directions, considering that the detector only observes a part of the sky, with a non uniform exposure and that the density of events depends on exposure.Moreover, the correlation between energy and position is analyzed including now experimental errors in the simulations. Correlated events with experimental errors plus background are simulated and methods of extracting the correlated structure, identifying its source and deducing information about the magnetic field are determined.Finally, conclusions are made, highlighting the most relevant results [es

  1. System tests, initial operation and first data of the AMIGA muon detector for the Pierre Auger Observatory

    Pontz, Michael

    2013-07-01

    Investigating the energy region between 10{sup 17} eV and 4 x 10{sup 18} eV for primary cosmic particles will lead to a deeper understanding of the origin of cosmic rays. Effects of the transition from galactic to extragalactic origin are expected to be visible in this region. The knowledge of the composition of cosmic rays strongly depends on the hadronic interaction models, which are applied in the air shower reconstruction. Directly determining the number of muons from an air shower on ground level will improve the precision of the composition measurements by reducing the dependence on the models. The Pierre Auger Observatory is facing these challenges with an upgrade of the original detector setup. A denser sub-array of water Cherenkov detectors and a dedicated muon detector (MD) array constitute the AMIGA enhancement (Auger Muon and Infill for the Ground Array). Additional fluorescence telescopes constitute HEAT (High Elevation Auger Telescopes). Seven MD modules have been installed until mid 2012 in a first hexagon at the site of the Pierre Auger Observatory in Malarguee, Argentina. The corresponding readout electronics, and 19 more of these setups, were assembled and tested in Siegen to assure correct functionality. The detectors were incorporated in the trigger structure of the original surface detector (SD) array of the Pierre Auger Observatory and are now taking data synchronously. In the framework of this thesis, system tests have been developed, a pre-unitary cell (PUC) of seven modules has been successfully operated and their trigger has been synchronised with the SD trigger. First data from the MD have been analysed and have been combined with data from the SD.

    Brown, Paul; Brown, Marta

    2015-03-01

    This is a report of a short-term, pastoral counselling group conducted with Jewish internees in a high security prison in Israel. It was held as an adjunct to daily secular individual and group counselling and rehabilitation run by the Department of Social Work. Pastoral counselling employed spiritual and psychosocial methodologies to reduce anger, improve prisoner frustration tolerance, and develop a sense of self-efficacy and communal identity. It combined semi-didactic scriptural input with Pierre Janet's personality model, Fritz Perls' gestalt therapy, and analysis of the group process. © The Author(s) 2015 Reprints and permissions:sagepub.co.uk/journalsPermissions.nav.

    This article provides information about an important period of Piaget's formative years, those he spent in Paris from 1919 to 1921, during which he came into contact with eminent members of the French scientific and philosophical community of the time. Among these was the psychiatrist and psychologist Pierre Janet, whose genetic approach to the psychology of behaviour and ideas about the hierarchical organization of psychological functions converged with Piaget's early scientific interests and provided Piaget a conceptual framework within which to work and develop his own project of studying the genesis of knowledge.

  11. Taming the forces between quarks and gluons calorons out of the box : scientific papers by Pierre van Baal

    CERN Document Server

    Van Baal, Pierre; Korthals Altes, Chris P

    2013-01-01

    This volume is a collection of selected papers by Pierre van Baal on the subject of quark-gluon interactions. He concentrates on semi-perturbative phenomena that occur when these particles are confined to a box. He introduced in 1998 the notion of calorons to explain what happens in the high temperature phase of the quark-gluon plasma. Van Baal's discoveries of the mathematical intricacies of twisted gluon field configurations have left their mark on the field, opening new directions for numerical simulations. This reprint is intended to be a comprehensive introduction for all those who wish to have deeper understanding of quark-gluon dynamics.

    Since data-taking began in January 2004, the Pierre Auger Observatory has been recording the count rates of low energy secondary cosmic ray particles for the self-calibration of the ground detectors of its surface detector array. After correcting for atmospheric effects, modulations of galactic cosmic rays due to solar activity and transient events are observed. Temporal variations related with the activity of the heliosphere can be determined with high accuracy due to the high total count rates. In this study, the available data are presented together with an analysis focused on the observation of Forbush decreases, where a strong correlation with neutron monitor data is found.

    2015-06-01

    Full Text Available Objetivo: Determinar factores de riesgo, relacionados con el estilo de vida, asociados con la presencia de deterioro cognitivo en personas mayores de 65 años. Método: Para ello se diseñó un estudio observacional transversal con personas mayores de 65 años no institucionalizadas mediante entrevista personal estructurada. El estudio se realizó en 14 farmacias de la Comunidad Valenciana desde marzo 2011 hasta marzo de 2013. Se utilizan como test de cribado el Short Portable Mental State Questionnaire (SPMSQ de Pfeiffer y el Mini-Mental State Examination (MMSE versión NORMACODERM de Blesa. Se definió deterioro cognitivo por SPMSQ ≥ 3 (para analfabetos ≥ 4 y/o MMSE ≤ 24. Resultados: Participaron en el estudio 729 personas. Se encontró que el 17,6% de los participantes (n = 128 presentaban resultados compatibles con deterioro cognitivo. Se determinó que dormir 9 o más horas diarias es causa o consecuencia y, por tanto, un factor de riesgo y/o de alarma en el desarrollo de deterioro cognitivo en personas mayores de 65 años. El ejercicio físico y pocas horas de sueño no obtuvo relación con el deterioro cognitivo. Conclusión: El cambio de hábitos de sueño en el anciano (pasar a dormir más horas es una señal de alerta para estudiar la presencia de un posible deterioro cognitivo.

Sectores que en ciudades como Bogotá, son mayoritarios y crecientes; con grandes carencias en lo económico y en lo social, así como en servicios e infraestructura urbana. Han crecido a espaldas de la planeación económica y urbana, y en gran medida se han desarrollado a partir de la iniciativa y posibilidades de sus propios habitantes. Han construido y apropiado su hábitat, han desarrollado y expresado sus sueños de futuro a partir de una construcción colectiva explícita e implícita, de una visión comunitaria no siempre compartida pero presente, y a través de unos mecanismos de participación a veces brindados y otras muchas exigidos. Se presentarán algunas reflexiones a partir de la exploración del tema en las periferias de Bogotá; reflexiones que fundamentalmente invitan a pensar con mayor seriedad y profundidad en el papel del poblador como agente de creación, transformación, mejoramiento y expresión de su hábitat urbano. Finalmente se harán algunas observaciones en torno a la pregunta que plantea el articulo: es la participación en el hábitat un sueño posible o una relación no deseada?

  17. Measurement of the ultra high energy cosmic ray flux from data of very inclined showers at the Pierre Auger Observatory

    International Nuclear Information System (INIS)

    Dembinski, Hans Peter

    2009-01-01

    This work describes the derivation of the energy dependent flux of ultra-high energy cosmic rays from data of very inclined air showers observed with the Pierre Auger Observatory. It focuses on the event class of very inclined air showers with zenith angles larger than 60 . The lateral ground profile of these showers is muon dominated and not radially symmetric around the shower axis due to geomagnetic deflections and other effects. The dependency of this profile on the direction, energy and mass of the cosmic ray is discussed with a mixture of detailed Monte-Carlo simulations and a simplified analytical model of the air shower cascade. It is found in agreement with other studies that the normalized shape of the muon density profile is approximately universal over the range of cosmic ray energies and masses measured at the Pierre Auger Observatory, that the amplitude of the profile is almost proportional to the cosmic ray energy, and that its shower-to-shower fluctuations are sensitive to the mass composition of the cosmic rays.

  19. The Pierre Auger Research and Development Array (RDA in southeastern Colorado – R&D for a giant ground array

    Directory of Open Access Journals (Sweden)

    Thompson J.

    2013-06-01

    Full Text Available The Pierre Auger Research and Development Array (RDA was originally designed to be the precursor of the northern Auger observatory, a hybrid array of 4400 surface detector stations and 39 fluorescence telescopes deployed over 20,000 square kilometers. It is conceived as a test bed aiming at validating an improved and more cost-effective 1-PMT surface detector design and a new peer-to-peer communication system. The array of ten surface detector stations and ten communication-only stations is currently being deployed in southeastern Colorado and will be operated at least until late 2013. It is configured in such a way that it allows testing of a new peer-to-peer communication protocol, as well as a new surface detector electronics design with a larger dynamic range aiming at reducing the distance from the shower core where saturation is observed. All these developments are expected in the short term to improve the performance of the Pierre Auger Observatory and enable future enhancements. In the longer term, it is hoped that some of these new developments may contribute to the design of a next-generation giant ground array.

    Full Text Available Sleeping disorders in type 2 diabetic patients constitute risk factors for aggravating diabetes since they can affect the metabolic control through insulin resistance syndrome. This was an observational, cross-sectional study. The majority (52% of subjects had scores indicating poor sleep quality. The Pittsburgh Sleep Quality Index (PSQI scores showed patients with a time after diagnosis over 10 years and hypertension had the poorest sleep quality. For those with hemoglobin A1c > 7% taking sleeping medicines and those who had normal body mass index (BMI, the sleep quality was even poorer. The findings of the present study reinforce the relevance of this topic since there are no specific tools for sleep evaluation of type 2 diabetics making it difficult to make any assertions on the sleep quality of these patients.Los disturbios del sueño en diabéticos del tipo 2, constituyen factores de riesgo para el agravamiento de la diabetes, pues pueden interferir en el control metabólico a través del síndrome de la resistencia a la insulina.

    Full Text Available El sistema de arreglo de disputas de la OME es muy estudiado y produce literatura muy divulgada. Sin embargo, hay pocos estudios empíricos sobre los perfiles de miembros de grupos especiales y del órgano de Apelación y, asimismo, su influencia en la articulación de un campo jurídico internacional al derredor de los órganos de arreglo de disputas. Ese estudio tiene el objetivo hacer disponibles algunas informaciones y analizarlas bajo la luz de algunos conceptos de la sociología de Pierre Bourdieu, en particular da de campo jurídico y de habitus, para comprender como se produce la jurificación internacional. Los resultados indican similitudes entre el campo jurídico de la omc y los campos jurídicos estatales.The WTO's dispute settlement system is a much studied subject and the literature thereon is widespread. Nevertheless, there are few empirical studies on panelists' and Appellate Body members' profiles as well as their influence on the articulation of an international legal field around the dispute resolution organizations. This study aims to make available some information on these profiles and analyze them under the light of some concepts of Pierre Bourdieu's sociology, mainly the legal field and the development of social habitus, in order to understand how international legalization of the trade law takes place. The results point out the similarities between the WTO's legal field and the state legal fields.

  11. A atividade humana, simultaneamente intelectual e vital: esclarecimentos complementares de Pierre Pastré e Yves Schwartz Human activity, both intellectual and vital: complementary approaches of Pierre Pastré and Yves Schwartz

    Full Text Available Toda situação de trabalho se presta a uma dupla abordagem. É o local onde se realiza uma tarefa, pensada anteriormente e provocadora de uma intensa atividade intelectual pelo trabalhador. Mas é igualmente um momento único da vida, com suas arbitragens. Nesse caso, a tarefa não é mais vista como primeira, ela entra no 'debate de normas' que caracteriza a atividade do trabalhador sob o ângulo vital, aquele das escolhas que um ser humano não cessa de fazer. Entendemos que essas duas perspectivas correspondem, respectivamente, à de Pierre Pastré e à de Yves Schwartz. Elas se completam e enriquecem a análise: seu entrecruzamento confere, notadamente, um destaque inédito à questão das competências.There can be a dual approach to every work situation. It is the place where a task is done, one which has been planned previously and which leads the worker to an intense intellectual activity. But it is also a unique moment in life, with its arbitrations. In this case, the task is no longer seen as the first. In fact, it enters the realms of the debate of rules that characterize the worker's activity from the critical perspective, the one of the choices a human being never ceases making. We believe these two perspectives correspond to Pierre Pastré and Yves Schwartz's views, respectively. They complement and enrich the analysis: the intersection between them gives rise, notably, to an unprecedented emphasis on the issue of skills.

    Full Text Available El síndrome de apnea obstructiva del sueño (SAOS constituye en la actualidad un problema de salud importante, tanto por su prevalencia como por la morbilidad que provoca sobre el aparato cardiovascular y la calidad de vida del paciente. Actualmente, la base del tratamiento es la administración de presión positiva continua durante el sueño (CPAP que, si bien tiene una elevada eficacia, no es tolerada en muchos casos. Los tratamientos quirúrgicos han sido variados. En un principio se centraron en el sistema velofaríngeo con mejorías no superiores al 50% a largo plazo. En nuestro planteamiento terapéutico identificamos, mediante pruebas funcionales y de imagen, las regiones implicadas en cada caso. Entre ellas destaca la base de la lengua. La técnica que presentamos constituye una modificación a las ya descritas para el avance de la base lingual. Consiste en una fijación controlada de la misma a la cortical vestibular de la mandíbula con un punto de hilo de monofilamento pasado a través de dos orificios, sin necesidad de aditamentos especiales. Conseguimos una estabilización permanente con buenos resultados clínicos y polisomnográficos a largo plazo. Las complicaciones estuvieron en relación con problemas deglutorios en el postoperatorio inmediato.Sleep apnoea síndrome constitutes an important health problem because of its prevalence and impact over the cardiovascular system and quality of life of the patient. The classic conservative treatment remains to be the CPAP. Although it has a high efficacy, it is not well tolerated by the patient in many cases. The surgical treatments were initially devoted to the velopharyngeal complex, being definitive in only 50% of the cases. Our therapeutical approach consists on a thorough examination of the different areas affected in every case, one of which is the tongue base. The surgical technique we present constitutes a modification of others already described to advance the tongue base. It

    Full Text Available Frente a las lecturas de orientación psicoanalítica (Premat, Corbatta, otro modo de leer a Saer tiende a resaltar el peso innegable del azar en su obra (Dalmaroni y Merbilhaá, Iglesia. Nuestra lectura intenta esclarecer la maniobra narrativa de Saer al orquestar el improbable matrimonio del azar con el psicoanálisis en Nadie nada nunca. Siguiendo a Baudrillard en Las estrategias fatales, el psicoanálisis tendió a “eliminar el azar de los lapsus, de los actos fallidos, de los sueños, de la locura”(162. Si la reunión de la causalidad y de la casualidad es problemática en la quinta novela de Saer, sostenemos que esta situación se debe al terror dictatorial. Para intentar probar esto, el trabajo ahonda en el sueño del Gato (cap. II que se desarrolla en un casino-prostíbulo. Este episodio –mise en abyme fundamental de la novela– nos permite adentrarnos en la alegorización de lo arbitrario dictatorial y es la ocasión de resaltar la maestría de Saer cuando instrumentaliza las colusiones de intereses azarosos y psicoanalíticos en una base económica cuestionable. In contrast with psychoanalytic readings (Premat, Corbatta, another way of reading Saer highlights the relevance of chance in his work (Dalmaroni and Merbilhaá, Iglesia. Both types of readings pose theoretical questions. Indeed, as Baudrillard puts it in Les stratégies fatales, “psychoanalysis […] and its unconscious interpretation have ruled out the accidental nature of lapsus, of Freudian slips, of dreams, of madness (162”. Our reading attempts to shed light on the literary project of the Argentinian writer as he plots the improbable relation of chance and psychoanalysis in his fifth novel, Nadie nada nunca. In this vein, the problematic coexistence of causality and chance can only be explained by the dictatorial terror that permeates this novel. To prove this, the article analyzes the oneiric world of El Gato (II, in which the freudian principle of

  15. Surgical Management of Pierre Robin Sequence: Using Mandibular Distraction Osteogenesis to Address Hypoventilation and Failure to Thrive in Infancy.

    Scott, Andrew R

    2016-04-01

    Mandibular hypoplasia may present in isolation or in the context of glossoptosis and a U-shaped, incomplete cleft palate. This latter triad is referred to as Pierre Robin sequence. Deleterious effects of micrognathia that may present during infancy are due primarily to glossoptosis or posterior displacement of the tongue. This tongue base prolapse may cause varying degrees of upper airway obstruction. A surgical option for management of tongue base airway obstruction secondary to mandibular hypoplasia is neonatal mandibular distraction osteogenesis. Herein, the author seeks to outline the benefits and limitations of early mandibular distraction osteogenesis as a way of managing airway obstruction and feeding difficulty in newborns with micrognathia. A description of the author's operative technique as well as potential complications and pitfalls will also be discussed. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

  17. Obtaining muonic density estimates via application of matrix formalism to proposed surface detector upgrade at the Pierre Auger Observatory

    Energy Technology Data Exchange (ETDEWEB)

    2015-07-01

    Event-by-event identification of cosmic ray primary composition lends itself to enhanced event selection in the search for anisotropic arrival directions. Principally, the number of muons reaching Earth's surface in an extensive air shower is indicative of composition. The Pierre Auger Observatory seeks to capitalize on this axiom by improving reconstructed muonic density estimates via an upgrade to its surface detector array. This upgrade, consisting of placing a scintillator on top of each existing water Cherenkov detector, exploits the differing response of two detectors to muonic and electromagnetic particles. Exploitation of this difference may be expressed in a matrix formalism whose application to simulated proton and iron showers is presented here.

    The DOE Spent Fuel and Waste Technology (SWFT) R&D Campaign is supporting research on crystalline rock, shale (argillite) and salt as potential host rocks for disposal of HLW and SNF in a mined geologic repository. The distribution of these three potential repository host rocks is limited to specific regions of the US and to different geologic and hydrologic environments (Perry et al., 2014), many of which may be technically suitable as a site for mined geologic disposal. This report documents a regional geologic evaluation of the Pierre Shale, as an example of evaluating a potentially suitable shale for siting a geologic HLW repository. This report follows a similar report competed in 2016 on a regional evaluation of crystalline rock that focused on the Superior Province of the north-central US (Perry et al., 2016).

    Energy-dependent patterns in the arrival directions of cosmic rays are searched for using data of the Pierre Auger Observatory. We investigate local regions around the highest-energy cosmic rays with E ≥ 6 x 10 19 eV by analyzing cosmic rays with energies above E ≥ 5 x 10 18 eVarriving within an angular separation of approximately 15 circle . We characterize the energy distributions inside these regions by two independent methods, one searching for angular dependence of energy-energy correlations and one searching for collimation of energy along the local system of principal axes of the energy distribution. No significant patterns are found with this analysis. The comparison of these measurements with astrophysical scenarios can therefore be used to obtain constraints on related model parameters such as strength of cosmic-ray deflection and density of point sources.

    Full Text Available En este artículo se ofrece una aproximación al concepto de reflexividad y a su función en la Teoría Social de Pierre Bourdieu. Se analizan los cambios sufridos por el marco conceptual de la reflexividad en el curso de la trayectoria del sociólogo francés, desde el significado puramente epistemológico de su primera época al contenido ético que recibe en su obra más tardía. La reflexividad es entonces entendida como una 'tecnología del yo', por utilizar las palabras de Foucault. De este modo se intenta explicar el giro é tico del último Bourdieu y el estilo de pensamiento promovido por su equipo de investigación.

    2005-01-01

    The paper describes the new design of the first level trigger for the surface array in the Pierre Auger Observatory. The previous design was tested in a small test segment called Engineering Array (EA). It confirmed full functionality and reliability of the PLD approach. However, because of the high price of the chips available at that time, a new cost-effective design was developed. Altera ( R) offered cost-effective family, which allows reducing the total budget of the electronics without compromise in the functionality. The here described concept of a splitting of data processing into two sub-channels implemented into the parallel working chips, the chips synchronization and the automatization of internal processing management, together with the fully pipelined AHDL code became the framework for the further implementation in the environmental condition of the Argentinian pampa

En este artículo hacemos un análisis comparativo del uso teórico y metodológico que hicieron de este concepto en la producción de su fecunda obra en los campos de la psicología y de la sociología, respectivamente. Para ello nos hemos centrado en cinco cuestiones cruciales que de modo explícito plantearon estos dos investigadores en la elaboración de su teoría de campo: la ruptura con las objetivaciones parciales, la construcción del objeto, la dinámica interna de los campos, la delimitación de sus fronteras y la representación matemática de los hechos psicológicos y sociológicos. Concluimos con una síntesis en la que ponemos de relieve algunas importantes coincidencias y diferencias en la teoría de campo de Kurt Lewin y Pierre Bourdieu. Ambos le asignaron funciones epistemológicas similares, pero podemos apreciar en Lewin un mayor mimetismo respecto a la noción de campo proveniente de la física y sus posibilidades de formulación matemática, mientras que en Bourdieu la noción de campo es inseparable de las de habitus y capital, lo que facilita un análisis más integrado de los fenómenos micro y macrosociales, una apreciación más sofisticada de sus dimensiones temporales y criterios más precisos para establecer los límites de un campo.

    Polifonie en kontrapunt: Meganismes van verleiding in die dagboeke van Helen Hessel en Henri Pierre Roché. Henri Pierre Roché (1879–1959, outeur van Jules et Jim, word beskryf as ‘n sosiale koppelaar, ‘n model-liefhebber van alles en nog wat, ‘n versamelaar van vroue en kuns en een van die mees produktiewe dagboekskrywers en aktiewe minnaars in die opgetekende geskiedenis. Roché het ‘n reeks sketse oor Don Juan gepubliseer en was geboei deur die figuur van die verleier. In sy twintigs beplan hy om sy lewe te wy aan die skepping van ‘n œuvre wat die morele, intellektuele, sosiale en seksuele verhoudings tussen mans en vrouens sou ondersoek. Ter bereiking van hierdie doel, rig hy sy lewe in as laboratorium waarin werklike ondervindinge dien as hoofbron van inligting. Sy dagboek strek oor sestig jaar en is ryk aan verhale van verleiding. Desnieteenstaande bly die mees intense en boeiende intrige van verleiding en verraad steeds sy verhouding met Helen Hessel. Aan die begin van hulle verhouding, stel Roché voor dat sy ook ‘n dagboek hou van hulle hartstogtelike liefde. Helen Hessel se dagboek, geskryf in Frans, Duits en Engels, reflekteer die drama van verleiding en funksioneer op verskillende vlakke: realisties, visionêr, ten volle geabsorbeer in haar eie gedagtes en emosies en tóg krities jeens haarself en ander. ‘n Vergelyking van die twee dagboeke skep ‘n fassinerende, digte tekstuur wat die binnewerkings blootlê van verleiding in aksie. Die kontrapunt geskep deur hierdie twee interafhanklike stemme word nóg meer kompleks namate ‘n mens bewus word van die intertekstuele verwysings wat bydra tot die ontluikende polifonie van geskrewe liefde en lewe.

    Full Text Available Daylighting using skylight has been shown to have a high potential in reducing electrical lighting energy, and could provide a more pleasant atmosphere of a daylit space. However, in hot climates, the main constraint of daylighting is the solar heat gain that contributes to major heat load for an air-conditioning system. If the balance between the beneficial light gain used to offset lighting energy requirement and heat gain from daylight is well considered, significant energy savings can be obtained. The main objective of the study is to evaluate the potential of daylighting for energy conservation in the tropics through theoretical analysis (simulation study and experimental observation. Lai Sue Thai Building (an existing and educational building located at Ramkhamkaeng University was selected as a case study. From analysis, use of daylight could reduce electrical energy in this building by up to 76% compared to the initial condition where fully lighting was supplied. Window orientation would also play an important role. Moreover, heat gain through windows due to daylighting can be controlled by overhangs and the appropriate Window-to-Wall ratio that would be about 30% for this building. An experimental study was also carried out to validate the results in a selected room. About 49% and 37% of Relative Root Mean Square Error (RRMSE were observed in light and heat measurements, respectively

    Full Text Available Este artículo procura describir y analizar procesos de des/clasificación, de/construcción y des/de/limitación de fronteras y grupos que se produjeron en la organización y puesta en marcha del evento “Un canto a la esperanza. 15 Años, Un Sueño”, recital realizado en el año 2010 en la ciudad de Córdoba, para festejar a jóvenes con “capacidades especiales” los quince años. Las preguntas que guían el escrito giran en torno a cómo se (redefinió y (renominó al grupo de agasajadas, cómo operó el marcador “15 años” en conjunción con sus condiciones de discapacidad, qué “soñaban” los organizadores y participantes con “esta gran fiesta de quince años”. Para ello, se analizan entrevistas radiales, notas periodísticas en portales de diarios locales y el propio registro de observación del evento. El objetivo del escrito es indagar en las políticas y poéticas a través de las cuales se articulan juventudes, Estado, religión, clase, público y audiencias.

    Full Text Available Resumen: Presentamos un nuevo abordaje mínimamente invasivo mediante distracción intraoral de rama mandibular bilateral (bilateral internal ramus distraction para el tratamiento del síndrome de apnea obstructiva del sueño en el paciente adulto. Tras la planificación virtual 3 D, el paciente es intervenido bajo anestesia general y asistencia endoscópica, dentro de un protocolo de cirugía mayor ambulatoria, y es dado de alta el mismo día de la cirugía. Tras un periodo de 5 días, la rama mandibular se alarga verticalmente durante un periodo que oscila entre 10 y 50 días, a un ritmo de 0,5 a 1 mm diario, hasta que el índice de apnea hipopnea alcanza una cifra inferior a 5 pausas por hora (nivel de curación o el resalte negativo dentario (overjet se sitúa en valores que ya superan los 10 mm.La titulación del procedimiento mediante parámetros clínicos, poligráficos o polisomnográficos permite al cirujano personalizar el avance mandibular en cada caso. Tras un alargamiento que suele oscilar entre 10 y 25 mm, los distractores se mantienen durante 6 meses hasta que concluye el periodo de consolidación. La indicación de cirugía maxilar tras el avance mandibular se realizará en dependencia del índice de apnea hipopnea residual, de la oclusión y del análisis facial.La distracción intraoral de rama mandibular bilateral es una técnica altamente efectiva para la curación del síndrome de apnea obstructiva del sueño en pacientes adultos con o sin retrognatia, y podría estar indicada incluso en pacientes con morbilidades asociadas, como enfermedades cardiovasculares graves u obesidad mórbida, en los que un procedimiento quirúrgico de mayor envergadura, como el avance maxilomandibular clásico, se descarta como alternativa quirúrgica.

Les réactions de pyrolyse, d'oxydation et de combustion mises en jeu par ces techniques sont discutées, en particulier la cinétique des principaux mécanismes réactionnels, l'importance du dépôt de coke et l'exothermicité des réactions d'oxydation et de combustion. Les résultats d'essais de déplacement unidirectionnel du front de combustion dans des cellules de laboratoire sont présentés et discutés. Enfin on indique les conditions pratiques d'application des méthodes de combustion in situ sur champ. Possible variations of in situ combustion technique ore as follows : forward or reverse combustion depending on the relative directions of the air flow and the combustion front, dry combustion if air is the only fluid injected into the oil-bearing formation, or fixe/woter flooding if water is injected along with air. The chemical reactions of pyrolysis, oxidation and combustion involved in these processes are described. The kinetics of these reactions is discussed as well as fuel availability in forward combustion and the exothermicity of the oxidation and combustion reactions. The results obtained in the laboratory when a combustion front propagates in unidirectional adiabatic tells are described and discussed. This type of experimentation provides extensive information on the characteristics of the processes. Screening criteria for the practical application of in situ combustion techniques are presented.

    Full Text Available As sociologias da literatura de Bourdieu e Williams estão apoiadas em dois conceitos fundamentais: “habitus” e “estruturas de sentimento”, respectivamente. E é clara a semelhança entre eles: ambos tentam traduzir uma espécie de consciência prática adquirida pelos agentes sociais a partir de um processo particular de socialização. Para o primeiro, o “habitus” é internalizado na experiência vivida num campo específi co; ao passo que, para o segundo, tal consciência é formada no interior dos grupos culturais. Nesse sentido, ambas as noções dizem respeito a um conjunto de valores compartilhados que aproximam e afastam certos agentes uns dos outros, criando solidariedade e rivalidades. Esta comunicação pretende demonstrar que, apesar das diferenças que existem, os conceitos dos autores não supervalorizam nem a reprodução nem a mudança social, mas, ao contrário, tentam explicar esses fenômenos como jogo dialético. Palavras-chave: Pierre Bourdieu. Raymond Williams. Sociologia da literatura. “Habitus”. Estruturas de sentimento. The literature sociologies of Bourdieu and Williams are structured in two fundamental concepts: “habitus” and “sentiment structures”, respectively. It’s very clear the resemblance between them: both try to translate a kind of practical conscience, acquired by the social agents from a particular socializing process. To the fi rst, the “habitus” is internalized in the living experience of a specifi c fi eld; while that to the second that conscience is formed in the interior of cultural groups. In this sense, both ideas talk about shared values which approximate and withdraw some agents one from the others, creating solidarity and competition. This text intends to show that, despite of the existing differences, the authors concepts don’t overestimate neither the reproduction, nor the social change, but, otherwise, try to explain these phenomena as a dialectic game.

    We report a measurement of the proton-air cross section for particle production at the center-of-mass energy per nucleon of 57 TeV. This is derived from the distribution of the depths of shower maxima observed with the Pierre Auger Observatory: systematic uncertainties are studied in detail. Analyzing the tail of the distribution of the shower maxima, a proton-air cross section of [505 {+-} 22(stat){sub -36}{sup +28}(syst)] mb is found.

    Full Text Available Valparaíso es el resultado de la unión de dos ciudades en una: la ciudad vertical de los cerros y la ciudad horizontal del Plan –parte plana–. Esta doble naturaleza ha ido configurando una dualidad obligada a convivir y a establecer un continuo diálogo, acabando en la mayoría de los casos en conflicto. Si por un lado está la ciudad global y ortogonal como resultado de la ocupación europea, por otro lado estará la ciudad onírica agarrada a los acantilados ajena a cualquier orden preestablecido. Cada una de estas dos ciudades irá materializando su propia arquitectura: una real y estandarizada, propia de cualquier periferia de ciudad, y otra imposible. Será esta segunda la que vaya evolucionando en un intento continuo de adaptación y será el propio lugar el encargado de rechazar cualquier construcción que no le sea propia. Esta dicotomía quedará plasmada en numerosos proyectos que nunca verán la luz. El objetivo del artículo será mostrar, a partir de numerosos proyectos inéditos descubiertos en Valparaíso, cómo la arquitectura pensada para los cerros nunca llegó a construirse y fue dando paso a unas construcciones a medio camino entre lo real y lo imaginario, entre la lógica y el sueño.

    Ultra-high-energy cosmic rays (UHECR) are particles of uncertain origin and composition, with energies above 1 EeV (1018 eV or 0.16 J). The measured flux of UHECR is a steeply decreasing function of energy. The largest and most sensitive apparatus built to date to record and study cosmic ray Extensive Air Showers (EAS) is the Pierre Auger Observatory. The Pierre Auger Observatory has produced the largest and finest amount of data ever collected for UHECR. A broad physics program is being carried out covering all relevant topics of the field. Among them, one of the most interesting is the problem related to the estimation of the mass composition of cosmic rays in this energy range. Currently the best measurements of mass are those obtained by studying the longitudinal development of the electromagnetic part of the EAS with the Fluorescence Detector. However, the collected statistics is small, specially at energies above several tens of EeV. Although less precise, the volume of data gathered with the Surface Detector is nearly a factor ten larger than the fluorescence data. So new ways to study composition with data collected at the ground are under investigation. The subject of this thesis follows one of those new lines of research. Using preferentially the time information associated with the muons that reach the ground, we try to build observables related to the composition of the primaries that initiated the EAS. A simple phenomenological model relates the arrival times with the depths in the atmosphere where muons are produced. The experimental confirmation that the distributions of muon production depths (MPD) correlate with the mass of the primary particle has opened the way to a variety of studies, of which this thesis is a continuation, with the aim of enlarging and improving its range of applicability. We revisit the phenomenological model which is at the root of the analysis and discuss a new way to improve some aspects of the model. We carry

  5. Detection of ultra-high-energy cosmic radiation at the Pierre Auger Observatory, theoretical study of its propagation through extragalactic space

    International Nuclear Information System (INIS)

    Allard, D.

    2004-10-01

    The Pierre Auger observatory's main aim is to observe the ultra-energetic cosmic ray spectrum with high statistics. Indeed, the spectrum around 10 20 eV is so far only poorly known, due to low statistics and the expected GZK (Gneisen-Zatsepin-Kuzmin) cut-off is for the time being not clearly observed. The first part will deal with propagation of charged (protons and nuclei) ultra-energetic cosmic rays in the extragalactic medium. We will investigate the influence of physical parameters, such as the composition of cosmic ray fluxes, on the highest energy spectrum shape. The influence of the turbulent extragalactic magnetic fields on the spectrum of the clusters will also be studied. We will also investigate the possibility to observe gamma ray bursts with the Pierre Auger Observatory by using the single particle technique. We will show how galactic gamma ray bursts could become a persistent and quasi-isotropic source due to the 'Compton trail' induced by Compton scattering of the primary photon beam in the interstellar medium. In the section devoted to simulations, we will develop methods to reconstruct air showers and identify primary cosmic rays. We will also study the aperture of the Surface Detector of the Pierre Auger observatory. Finally, we will use the methods developed in the previous chapters to analyze the data of the year 2004 and will give preliminary results. (author)

Para isso, propõe-se a visualização de um percurso teórico que apresenta brevemente o conceito de natureza desde a Física aristotélica até a interpretação da possibilidade de uma ontologia da contingência  no pensamento do Estagirita, o que é realizado com base na hipótese interpretativade Pierre Aubenque. A consequência da defesa do estabelecimento de um lugar para a indeterminação e a imprevisibilidade, características da ação humana, fortalece a concepção de deliberação e demonstra a importância deste conceito para a política em Aristóteles, algo que justifica a relevância da presente proposta de trabalho.

    2001-11-01

    Cosmic radiations of ultra high energy (RCUHE, beyond 10{sup 18} eV) are difficult to study because of their low flux on the earth surface: about 1 photon per year and per km{sup 2}. The observatory Pierre Auger proposes to study RCUHE by designing 2 sites of 3000 km{sup 2} (one in each hemisphere) allowing the observation of the shower initiated by cosmic radiation by using 4 fluorescence telescopes and a network of 1600 Cherenkov detectors. The identification of the primary particle is a very delicate point, the detection of neutrino or photon at these energies would bring valuable information for the understanding of potential sources of RCUHE. The first part of this work presents the project and its assets to perform its task. The second part is dedicated to the description of the Cherenkov detectors, of the trigger system, and of the centralized data acquisition system. The last part present the prototype installation that is under construction at Macargue in Argentina. (A.C.)

    Full Text Available This study aimed to evaluate surgical-oncologic patients' quality of sleep through the Pittsburgh Sleep Quality Index (PSQI questionnaire. It is an exploratory study with transversal-observational design, in 46 postoperative head & neck and urology cancer patients. The PSQI questionnaire was used to evaluate the subjective quality of sleep and the occurrence of sleep disorders. Six PSQI components were statistically significant and 78.3% of the interviewees had impaired subjective quality of sleep. Among factors leading to sleep disorders we point out: taking too long to fall asleep; waking up in the middle of the night; getting up to go to the bathroom and napping during the day. This study is expected to sensitize the nursing team regarding the need to investigate quality of sleep and causes of its disorders in cancer survivors for an effective course of action.El objetivo del estudio fue evaluar la calidad del sueño en pacientes quirúrgicos oncológicos, utilizando el cuestionario Índice de Calidad del Sueño de Pittsburgh (PSQI, para mensurar la calidad subjetiva del sueño y la ocurrencia de disturbios.

  16. A measurement of the muon number in showers using inclined events detected at the Pierre Auger Observatory

    Directory of Open Access Journals (Sweden)

    Rodriguez G.

    2013-06-01

    Full Text Available The average muon content of measured showers with zenith angles between 62∘ and 80∘ detected at the Pierre Auger Observatory is obtained as a function of shower energy using a reconstruction method specifically designed for inclined showers and the hybrid character of the detector. The reconstruction of inclined showers relies on a comparison between the measured signals at ground and reference patterns at ground level from which an overall normalization factor is obtained. Since inclined showers are dominated by muons this factor gives the relative muon size. It can be calibrated using a subsample of showers simultaneously recorded with the fluorescence detector (FD and the surface detector (SD which provides an independent calorimetric measurement of the energy. The muon size obtained for each shower becomes a measurement of the relative number of muons with respect to the reference distributions. The precision of the measurement is assessed using simulated events which are reconstructed using exactly the same procedure. We compare the relative number of muons versus energy as obtained to simulations. Proton simulations with QGSJETII show a factor of 2.13 ± 0.04(stat ± 0.11(sys at 1019eV without significant variations in the energy range explored between 4 × 1018eV to 7 × 1019eV. We find that none of the current shower models, neither for proton nor for iron primaries, are able to predict as many muons as are observed.

    Full Text Available Malapari (Pongamia pinnata (L. Pierre is an oil-producing plant which has the potential for biodiesel feedstock. This becomes a reason that Malapari plants need to be developed and cultivated. Malapari grow naturally in lowland forests on calcareous soils, rocks on the beach, along the edge of the mangroves and along stream and river tides. This study aims to determine the characteristics of Malapari and relationship between the two accessions grown in North Bali (Pemaron, Uma Anyar, Kalisada, Pengulon, Sumber Kelampok and East Java (Alas Purwo National Park and Baluran National Park based on morphological characters and oil content. The research was conducted in July-November 2015. The method used in this research was observation of morphological characters as well as the analysis of the oil content of seeds. Relationship among trees that grow in the two accessions was analyzed using Minitab Vis 14. Results showed that there were differences in morphological characteristics, namely the leaves, flowers, fruits, pod and seeds dimension and oil content.  Analysis of relationships among trees at similarity level above 80% classified them into 3 major groups, namely group I Malapari from Uma Anyar village with similarity level of 59,51%, group II Malapari from  Pengulon village with  similarity level of 80,16% and group III  Malapari from  Alas Purwo National Park and 32 other trees from various villages  having similarity level of 84,53%.

    To test the hypothesis that a new orthodontic appliance with a velar extension that shifts the tongue anteriorly would reduce upper airway obstruction in infants with Pierre Robin sequence (PRS). Eleven infants with PRS (median age, 3 days) and an apnea index (AI) >3 were studied. The effect of the new appliance on the AI was compared with that of a conventional appliance without a velar extension by using a crossover study design with random allocation. Compared with baseline (mean AI, 13.8), there was a significant decrease in the AI with the new appliance (3.9; P value appliance (14.8; P = .842). Thus, the relative change in AI was -71% (95% CI, -84--49) for the new appliance and +8% (95% CI, -52-142) for the conventional appliance, which was significantly different (P = .004). No severe adverse effects were observed. This new orthodontic appliance appears to be safe and effective in reducing upper airway obstruction in infants with PRS.

    An in-situ calibration of a logarithmic periodic dipole antenna with a frequency coverage of 30 MHz to 80 MHz is performed. Such antennas are part of a radio station system used for detection of cosmic ray induced air showers at the Engineering Radio Array of the Pierre Auger Observatory, the so-called Auger Engineering Radio Array (AERA) . The directional and frequency characteristics of the broadband antenna are investigated using a remotely piloted aircraft carrying a small transmitting antenna. The antenna sensitivity is described by the vector effective length relating the measured voltage with the electric-field components perpendicular to the incoming signal direction. The horizontal and meridional components are determined with an overall uncertainty of 7.4+0.9-0.3% and 10.3+2.8-1.7% respectively. The measurement is used to correct a simulated response of the frequency and directional response of the antenna. In addition, the influence of the ground conductivity and permittivity on the antenna response is simulated. Both have a negligible influence given the ground conditions measured at the detector site. The overall uncertainties of the vector effective length components result in an uncertainty of 8.8+2.1-1.3% in the square root of the energy fluence for incoming signal directions with zenith angles smaller than 60°.

    Full Text Available Este artigo procura contribuir para as discussões em torno do conceito histórico de educação integral, tendo em vista que existem algumas lacunas em torno desse tema. Aqui iremos abordar os conceitos de educação integral no pensamento dos intelectuais: Claude-Henri de Rouvroy ou Conde de Saint-Simon (1760-1825, François Marie Charles Fourier (1772-1837 e Pierre-Joseph Proudhon (1809-1865. A pesquisa utiliza as obras dos autores escritas/publicadas no século XIX. A metodologia procura entender a produção intelectual de maneira dialética e dentro do contexto histórico em que foi produzida. Indicamos como conclusões que Proudhon, Saint-Simon e Charles Fourier, consideravam no processo educacional que a parte literária estaria diretamente vinculada com a científica, unindo teoria e prática. Podemos aventar que as contribuições desses pensadores foram importante nas reflexões educacionais e na defesa de uma educação comprometida com a transformação social presente no pensamento socialista e no movimento operário do século XIX e XX.

  1. Study of ultra-energetic cosmic rays at the Pierre Auger Observatory from particle detection to anisotropy measurement

    2006-09-01

    The Pierre Auger Observatory, still under construction in Argentina, is designed to study the cosmic rays with energies above a few EeV. The experiment combines two complementary techniques: the fluorescence light detection and the sampling of the shower with an array of detectors at ground, covering a surface of 3000 square kilometers. The calculation of the acceptance of the detector, which is of utmost importance to establish the energy spectrum, has been achieved. The method of computation of the acceptance is simple and reliable. The detection efficiency depends on the nature of primary cosmic rays, allowing to study the cosmic rays composition with the surface detector. The calculation of the cosmic rays energy spectrum has been performed, using different methods to estimate the energy of the events. A cross calibration between the fluorescence and the surface detector provides an estimation of the energy almost independent of hadronic interaction models. The study of large scale anisotropies in the cosmic rays angular distribution provides useful informations about the cosmic rays sources and the conditions of propagation. A new analysis method is presented, allowing to estimate the parameters of an underlying dipolar and quadrupolar anisotropy in the data. The method is applied to a preliminary Auger data set.

    Full Text Available The review study focused on Czech translation of Pierre Hadot’s Qu’est-ce que la philosophie antique? is divided into three parts. In the first part the motivation behind the question “what is ancient philosophy?” is considered. On the one hand, Hadot aims to show that usual contemporary understanding of philosophy with its emphasis on discourse and theory does not provide adequate perspective to interpret ancient philosophy in its own right and thus the question on its nature must be asked anew. On the other hand, Hadot sees the core of ancient philosophy in specific praxis, not in theory, and this concept serves as norm for critical revision of the contemporary philosophy. The second part is addressed to the content of the chapters. The study accentuates that Hadot offers not only a description of various ancient philosophical schools and movements, but also presents a certain genealogy of the contemporary understanding of philosophy. The final part is dedicated to brief critical assessment of Hadot’s book and draws several conclusions concerning the institutional character of philosophy with regard to present crisis of humanities from its perspective.

    We report a multi-resolution search for anisotropies in the arrival directions of cosmic rays detected at the Pierre Auger Observatory with local zenith angles up to 80(o) and energies in excess of 4 EeV (4 × 1018 eV). This search is conducted by measuring the angular power spectrum and performing a needlet wavelet analysis in two independent energy ranges. Both analyses are complementary since the angular power spectrum achieves a better performance in identifying large-scale patterns while the needlet wavelet analysis, considering the parameters used in this work, presents a higher efficiency in detecting smaller-scale anisotropies, potentially providing directional information on any observed anisotropies. No deviation from isotropy is observed on any angular scale in the energy range between 4 and 8 EeV. Above 8 EeV, an indication for a dipole moment is captured, while no other deviation from isotropy is observed for moments beyond the dipole one. The corresponding p-values obtained after accounting for searches blindly performed at several angular scales, are 1.3 × 10-5 in the case of the angular power spectrum, and 2.5 × 10-3 in the case of the needlet analysis. While these results are consistent with previous reports making use of the same data set, they provide extensions of the previous works through the thorough scans of the angular scales.

  4. Search for first harmonic modulation in the right ascension distribution of cosmic rays detected at the Pierre Auger Observatory

    Full text: The large-scale distribution of the arrival directions of Ultra-High Energy Cosmic Rays (UHECRs) is, together with the spectrum and the mass composition, an important observable in attempts to understand their nature and origin. In this work we show the results of searches for dipolar-type anisotropies in different energy ranges above 2.5 x 10 17 eV with the surface detector array of the Pierre Auger Observatory. For events with energy above 1 EeV we present searches for first harmonic modulations in right-ascension based on the classical Rayleigh analysis slightly modified to account for the small variations of the exposure. The results for events with energy below 1 EeV are derived using simple event counting rate differences between Eastward and Westward directions in order to take into account the detector-dependent variations in the counting rate because in this range of energy the detection efficiency of the array depends on zenith angle and composition. Using relative rates, this technique allows a search for anisotropy in right ascension without requiring any evaluation of the detection efficiency. Upper limits on the amplitudes are obtained, which provide the most stringent bounds at present, being below 2% at 99% C.L. for EeV energies. We also compare our results to those of previous experiments as well as with some theoretical expectations. (author)

    Full Text Available Ricinodendron heudelotii (Baill. Pierre ex Pax. kernel (njansang commercialization has been promoted by the World Agroforestry Centre (ICRAF in project villages in Cameroon with the aim to alleviate poverty for small-scale farmers. We evaluated to what extent development interventions improved the financial situation of households by comparing project and control households. The financial importance of njansang to household livelihoods between 2005 and 2010 was investigated through semi-structured questionnaires with retrospective questions, focus group discussions, interviews and wealth-ranking exercises. The importance of njansang increased strongly in the entire study region and the increase was significantly larger in project households. Moreover, absolute numbers of income from njansang commercialization as well as relative importance of njansang in total cash income, increased significantly more in project households (p < 0.05. Although the lower wealth class households could increase their income through njansang trade, the upper wealth class households benefited more from the projects' interventions. Group sales as conducted in project villages did not lead to significantly higher prices and should be reconsidered. Hence, promotion of njansang had a positive effect on total cash income and can still be improved. The corporative actors for njansang commercialization are encouraged to adapt their strategies to ensure that also the lower wealth class households benefit from the conducted project interventions. In this respect, frequent project monitoring and impact analysis are important tools to accomplish this adaptation.

    Pierre Robin sequence (PRS) is an important subgroup of cleft palate. We report several lines of evidence for the existence of a 17q24 locus underlying PRS, including linkage analysis results, a clustering of translocation breakpoints 1.06-1.23 Mb upstream of SOX9, and microdeletions both approximately 1.5 Mb centromeric and approximately 1.5 Mb telomeric of SOX9. We have also identified a heterozygous point mutation in an evolutionarily conserved region of DNA with in vitro and in vivo features of a developmental enhancer. This enhancer is centromeric to the breakpoint cluster and maps within one of the microdeletion regions. The mutation abrogates the in vitro enhancer function and alters binding of the transcription factor MSX1 as compared to the wild-type sequence. In the developing mouse mandible, the 3-Mb region bounded by the microdeletions shows a regionally specific chromatin decompaction in cells expressing Sox9. Some cases of PRS may thus result from developmental misexpression of SOX9 due to disruption of very-long-range cis-regulatory elements.

    This article reviews and discusses scientific papers on eating practices that have used Pierre Bourdieu's concepts presented in Distinction: A Social Critique of the Judgement of Taste. It aims to synthesize and analyze theoretical and empirical studies on the theme in order to present Bourdieu's contributions to the field, advances in his theories, and directions for future research. Exclusion criteria were: not written in Portuguese, English, Spanish, or French; not published in a peer-reviewed journal; not analyzing food or eating; and not using Bourdieu's concepts as presented in Distinction as the main theoretical framework. In this narrative review, we found 38 articles, which were categorized main themes: food choice and provisioning, taste, social class, food symbolism, the body, and the scientific field of food and eating. The taste of luxury and the taste of necessity were broadly applied on the works found in this review and were observed among the lower and upper classes, manifesting differently in each class. These studies show that while Bourdieu's theories are still highly relevant to understanding contemporary social groups, they may be improved when combined with other frameworks and theorists. We highlight as directions for future research manners in which gender and the environment interact with the habitus and food choices. Finally, this review points to new areas of investigation that may help improve the use of Bourdieu's concepts in exploring health inequalities, such as differences in eating practices and habitus within populations with low socioeconomic status.

    Based on the theoretical and empirical approach of Pierre Bourdieu, a multivariate non-linear method is introduced as an alternative way to analyse the complex relationships between social determinants and health. The analysis is based on face-to-face interviews with 695 randomly selected respondents aged 30 to 59. Variables regarding socio-economic status, life circumstances, lifestyles, health-related behaviour and health were chosen for the analysis. In order to determine whether the respondents can be differentiated and described based on these variables, a non-linear canonical correlation analysis (OVERALS) was performed. The results can be described on three dimensions; Eigenvalues add up to the fit of 1.444, which can be interpreted as approximately 50 % of explained variance. The three-dimensional space illustrates correspondences between variables and provides a framework for interpretation based on latent dimensions, which can be described by age, education, income and gender. Using non-linear canonical correlation analysis, health characteristics can be analysed in conjunction with socio-economic conditions and lifestyles. Based on Bourdieus theoretical approach, the complex correlations between these variables can be more substantially interpreted and presented.

    Introduction Pierre Robin sequence (PRS) is characterized by microgenia and retrognathia. Cleft palate and glossoptosis are frequently associated with airway obstruction and difficulty in swallowing. Distraction osteogenesis with micro-distractors has recently been considered as a surgical option during the neonatal age. Case presentation A 6-week-old female with PRS underwent mandibular lengthening in neonatal age. Mandibular osteotomies were performed with the piezoelectric scalpel. Discussion Piezosurgery represents an innovative technique as it offers the maxillofacial surgeon the opportunity to make precise bone cuts without damaging the soft tissue, minimizing the invasiveness of the surgical procedure, and the opportunity of working in a field which is almost totally blood free. Conclusion The use of a piezoelectric device to perform this kind of surgery provides clinical and surgical results which would be difficult with traditional instruments, not only for the patient’s benefit but also for the surgeon’s. Preservation of the original bony structure, especially of the cancellous bone, will benefit the bone healing process due to its high estrogenic potential. PMID:25555147

    Pierre-Robin syndrome (PRS) is often associated with difficulty in endotracheal intubation. We present the use of percutaneous dilational tracheotomy (PDT) for airway management of a newborn with PRS and a glossopharyngeal web. A 2-day-old term newborn with PRS and severe obstructive dyspnea was evaluated by the anesthesiology team for airway management. A direct laryngoscopy revealed a glossopharyngeal web extending from the base of the tongue to the posterior pharyngeal wall. The infant was spontaneously breathing through a 2 mm diameter fistula in the center of this web. It was decided that endotracheal intubation was impossible, and a PDT was planned. The trachea of the newborn was cannulated, using a 20 gauge peripheral venous catheter and a 0.71 mm guide wire was introduced through this catheter. Using 5 French, 7 French, 9 French, and 11 French central venous catheter kit dilators, staged tracheotomy stoma dilation was performed. By inserting a size 3.0 tracheotomy cannula, PDT was successfully completed in this newborn. This case describes the successful use of PDT for emergency airway management of a newborn with PRS and glossopharyngeal web.

    We report a multi-resolution search for anisotropies in the arrival directions of cosmic rays detected at the Pierre Auger Observatory with local zenith angles up to 80{sup o} and energies in excess of 4 EeV (4 × 10{sup 18} eV). This search is conducted by measuring the angular power spectrum and performing a needlet wavelet analysis in two independent energy ranges. Both analyses are complementary since the angular power spectrum achieves a better performance in identifying large-scale patterns while the needlet wavelet analysis, considering the parameters used in this work, presents a higher efficiency in detecting smaller-scale anisotropies, potentially providing directional information on any observed anisotropies. No deviation from isotropy is observed on any angular scale in the energy range between 4 and 8 EeV. Above 8 EeV, an indication for a dipole moment is captured; while no other deviation from isotropy is observed for moments beyond the dipole one. The corresponding p -values obtained after accounting for searches blindly performed at several angular scales, are 1.3 × 10{sup −5} in the case of the angular power spectrum, and 2.5 × 10{sup −3} in the case of the needlet analysis. While these results are consistent with previous reports making use of the same data set, they provide extensions of the previous works through the thorough scans of the angular scales.

    Full Text Available Este artículo se propone indagar las consecuencias teóricas y analíticas que posee el estudio del suicidio egoísta en la perspectiva de Durkheim. Para ello, en primer lugar, se reconstruye en su obra El Suicidio la distinción entre egoísmo y anomia, destacando tanto la importancia del egoísmo, muchas veces relegado por la literatura secundaria, como la relación de éste con las crisis de sentido. Con ese objetivo, se señala la diferencia entre las esferas sociales activas y pasivas como elemento central para comprender ese par conceptual. En segundo lugar, se rastrea en las postulaciones del autor la génesis social de la pregunta por el sentido, lo cual conlleva a un estudio del desarrollo histórico de las religiones y de las manifestaciones individuales del egoísmo (melancolía, languidez, solipsismo. En tercer lugar, se observa cómo el despliegue histórico de la razón señala la emergencia del idealismo simbólico, el cual supone una falta de integración social enmarcado en una serie de procesos: la desarticulación entre pensamiento y acción y entre creencias sofisticadas y prácticas; la pérdida de un objeto durable (representacional y “mundano” y de una representación totalizante; y la carencia de objetivos comunes de la sociedad. En última instancia, se analiza cómo la sociología, en tanto ciencia de lo social, puede intervenir en las patologías vinculadas a los “sueños de la razón” de las corrientes egoístas (pasivos y solipsistas; activos y destructores. Así, se vislumbran las diferentes búsquedas del autor por encontrar en la modernidad nuevos modos de articular representaciones de la totalidad de la sociedad con prácticas diarias, los cuales puedan dar sentido a los individuos racionalizados. Allí, el lugar del Estado, los rituales colectivos y los ideales de la humanidad y el patriotismo pueden ser releídos desde los interrogantes y propuestas teóricas que están en juego en el an

    The history of cosmic rays started in the beginning of the 20th century. Since then one of the main questions is their origin. Due to the very low flux at the highest energies huge areas have to be instrumented to answer this question. For this purpose the distribution of the arrival directions of cosmic rays is studied. The largest experiment so far is the Pierre Auger Observatory, located in the Pampa in western Argentina with an area of about 3000 km{sup 2}. In recent years it provided many major contributions to the field of cosmic ray physics and its data is the basis of this work. Among other things a correlation analysis of Ultra High Energy Cosmic Rays (UHECRs) with Active Galactic Nuclei (AGN) was performed leading to the first evidence that UHECRs are not isotropically distributed. Here the distribution of arrival directions of cosmic rays at the highest energies (>50 EeV) is examined by using autocorrelation methods to check whether it is compatible with the isotropic expectation or not.This thesis is organised as follows: in the first two chapters a short introduction to the topic is given, followed by a more general discussion on cosmic rays including models of acceleration, possible sources and the propagation of UHECRs in the third chapter.

Of the extracts tested, the bark extract, obtained with aqueous methanol, exhibited greater levels of total phenolics [6.94 g GAE/100 g dry weight (DW], total flavonoids (3.44 g CE/100 g DW, inhibition of linoleic acid peroxidation (69.23% and DPPH radical scavenging activity (IC50 value, 3.21 μg/mL, followed by leaves and seeds extracts. Bark extract tested against a set of bacterial and fungal strains also revealed the strongest antimicrobial activity with the largest inhibition zone and lowest minimum inhibitory concentration (MIC. HPLC analysis of aqueous methanol extracts from bark, leaves and seeds indicated the presence of protocatechuic, ellagic, ferulic, gallic, gentisic, 4-hydroxybenzoic and 4-hydroxycinnamic acids in bark (1.50–6.70 mg/100 g DW; sorbic, ferulic, gallic, salicylic and p-coumaric acids in leaves (1.18–4.71 mg/100 g DW; vanillic, gallic and tannic acids in seeds (0.52–0.65 mg/100 g DW as the main phenolic acids. The present investigation concludes that the tested parts of P. pinnata, in particular the bark, have strong potential for the isolation of antioxidant and antimicrobial agents for functional food and pharmaceutical uses.

  1. A search for anisotropy in the arrival directions of ultra high energy cosmic rays recorded at the Pierre Auger Observatory

    2012-01-01

    Observations of cosmic ray arrival directions made with the Pierre Auger Observatory have previously provided evidence of anisotropy at the 99% CL using the correlation of ultra high energy cosmic rays (UHECRs) with objects drawn from the Veron-Cetty Veron catalog. In this paper we report on the use of three catalog independent methods to search for anisotropy. The 2pt-L, 2pt+ and 3pt methods, each giving a different measure of self-clustering in arrival directions, were tested on mock cosmic ray data sets to study the impacts of sample size and magnetic smearing on their results, accounting for both angular and energy resolutions. If the sources of UHECRs follow the same large scale structure as ordinary galaxies in the local Universe and if UHECRs are deflected no more than a few degrees, a study of mock maps suggests that these three methods can efficiently respond to the resulting anisotropy with a P-value = 1.0% or smaller with data sets as few as 100 events. Using data taken from January 1, 2004 to July 31, 2010 we examined the 20, 30, ..., 110 highest energy events with a corresponding minimum energy threshold of about 51 EeV. The minimum P-values found were 13.5% using the 2pt-L method, 1.0% using the 2pt+ method and 1.1% using the 3pt method for the highest 100 energy events. In view of the multiple (correlated) scans performed on the data set, these catalog-independent methods do not yield strong evidence of anisotropy in the highest energy cosmic rays.

    Full Text Available Before he became a Franciscan (November 1358, 12th infant Peter of Aragon wrote a king's mirror (Pe regimine principum dedicated to his nefew, King Peter IV of Aragon. In this text, known from a single 18th Century manuscript, he describes the ideal king and advises him. Thanks to its sources and many quotations and explanations, this text is quite close to biblical commentaries and sermons, but its structure and lack of Aristotelian quotations distinguish it from Gilles' of Rome famous De regimine principum. Infant Peter's is also very influenced by his political pragmatism at the beginning of the war against Castila: he recognises king's power is limited and dependant from his subjects' military and financial support.

    Peu avant sa profession chez les franciscains (12 novembre 1358, l'infant Pierre d'Aragon rédige un miroirs des princes, le De regimine principum dédié au roi Pierre IV d'Aragon son neveu et conservé dans un unique manuscrit du XVIIIe siècle. Il y dresse le portrait du souverain idéal et multiplie les conseils au roi. Par ses sources, l'abondance des citations et leur explication, ce miroir se rapproche aussi des commentaires bibliques et des sermons. Par sa structure et l'absence de références au corpus aristotélicien, il se distingue cependant de son homonyme, le De regimine principum de Gilles de Rome. Il est enfin remarquable par l'actualité et le pragmatisme politiques qui s'expriment dans son discours. L'auteur admet les limites posées au pouvoir royal, par sa dépendance militaire et financière envers les sujets au début de la guerre de Castille, et, par ses conseils, il invite Pierre le Cérémonieux à les dépasser.

    An upper limit of 16% (at 95% c.l.) is derived for the photon fraction in cosmic rays with energies above 10{sup 19} eV, based on observations of the depth of shower maximum performed with the hybrid detector of the Pierre Auger Observatory. This is the first such limit on photons obtained by observing the fluorescence light profile of air showers. This upper limit confirms and improves on previous results from the Haverah Park and AGASA surface arrays. Additional data recorded with the Auger surface detectors for a subset of the event sample, support the conclusion that a photon origin of the observed events is not favored.

    After being appointed "premier physician" in 1731, Pierre Chirac, thanks to his influence with the king, tried to realize an ambitious project. Inspired by the creation of an Academie de Chirurgie by the "premier surgeon", Chirac decided to creation an Académie de Médecine in Paris. Under his guidance, it was planned to collect opinions from all doctors of the kingdom in order to enhance global knowledge of disease, symptoms and treatments. However, threatened with the loss of its secular superiority, the Paris University Medical School immediately opposed the project. Although well advanced, the project was finally abandoned on Chirac's death.

    Before Vivant Denon, the dealer Jean-Baptiste-Pierre Lebrun played a crucial role in the creation of the Louvre collections, despite the revolutionary discourse which opposed the market to the museum. Lebrun's position as a polemicist is interpreted here as a strategy of self-presentation which made possible the controversial birth of the figure of the museum expert. With Lebrun, the Louvre imposed itself as a public space of artistic expertise, where values imported from the market - such as attributionism, materiality, and authenticity - became prominent in the evaluation of paintings.

Detection of ultra-high-energy cosmic radiation at the Pierre Auger Observatory, theoretical study of its propagation through extragalactic space; Detection des rayons cosmiques ultra-energetiques avec l'observatoire Pierre Auger et etude theorique de leur propagation dans le milieu extragalactique

    The Pierre Auger observatory's main aim is to observe the ultra-energetic cosmic ray spectrum with high statistics. Indeed, the spectrum around 10{sup 20} eV is so far only poorly known, due to low statistics and the expected GZK (Gneisen-Zatsepin-Kuzmin) cut-off is for the time being not clearly observed. The first part will deal with propagation of charged (protons and nuclei) ultra-energetic cosmic rays in the extragalactic medium. We will investigate the influence of physical parameters, such as the composition of cosmic ray fluxes, on the highest energy spectrum shape. The influence of the turbulent extragalactic magnetic fields on the spectrum of the clusters will also be studied. We will also investigate the possibility to observe gamma ray bursts with the Pierre Auger Observatory by using the single particle technique. We will show how galactic gamma ray bursts could become a persistent and quasi-isotropic source due to the 'Compton trail' induced by Compton scattering of the primary photon beam in the interstellar medium. In the section devoted to simulations, we will develop methods to reconstruct air showers and identify primary cosmic rays. We will also study the aperture of the Surface Detector of the Pierre Auger observatory. Finally, we will use the methods developed in the previous chapters to analyze the data of the year 2004 and will give preliminary results. (author)

Na medida em que esta é a abordagem psicoterápica mais indicada para dependência química, os sonhos, utilizados na Terapia Psicanalítica, tiveram de ser estudados sob o enfoque cognitivo-comportamental, para que pudessem ser aproveitados na clínica com estes pacientes. As alterações no sono de alcoolistas, por exemplo, pode servir como alerta quanto a um risco de recaída, o que indica que a avaliação do sono não pode ser desconsiderada pelos profissionais, durante o tratamento destes pacientes. O relato dos sonhos, por sua vez, pode ser um instrumento terapêutico muito valioso por oferecer pistas a respeito do quanto o craving está presente naqueles que estão tentando manter-se em abstinência. Se os profissionais forem bem sucedidos quanto à identificação precoce de uma situação de risco como o craving, poderão ser mais efetivos quanto à prevenção da recaída. Conclui-se quanto à necessidade de que sejam feitas novas pesquisas a respeito dos sonhos de acordo com esta abordagem teórica, bem como avaliada a sua aplicação na área da dependência química.Este trabajo tiene como objetivo realizar uma revisión teórica a respecto del sueño y de los sueños de alcohólicos, teniendo en vista la Terapia Cognitivo-Comportamental, profundizando aspectos cognitivos y neurológicos.

    Full Text Available El síndrome de apnea obstructiva del sueño (SAOS se caracteriza por ronquidos, pausas en la respiración y somnolencia diurna excesiva entre los síntomas más relevantes. Se ha demostrado una asociación con incremento de riesgo vascular en pacientes con SAOS. Objetivo: Evaluar si el personal médico busca síntomas relacionados al SAOS en pacientes con un cuadro cerebrovascular o síndrome coronario agudo, en los servicios de Medicina del Hospital Nacional Cayetano Heredia en Lima, Perú, desde septiembre del 2003 hasta septiembre del 2004. Materiales y métodos: Se planteó un estudio observacional retrospectivo. Se revisaron historias clínicas de 291 pacientes con diagnóstico al ingreso de accidente cerebrovascular, ataque isquémico transitorio o síndrome coronario agudo, buscando información sobre síntomas relacionados al SAOS, incluyendo evaluación por especialidades y epicrisis, detallando los evaluadores que recogieron los datos. Resultados: En la evaluación de 291 pacientes participaron 1122 evaluadores, 0,98 % de ellos consignó descartar el SAOS, que correspondió a 9 pacientes. En sólo 1 paciente se sugirió realizar un estudio de polisomnografía para corroborar el diagnóstico, sin ofrecerse ninguna opción terapéutica. Del total de pacientes, en el 6,87 % se indagó por ronquidos durante el sueño, 28,52 % por somnolencia y 0,68 % por episodios de apneas durante el sueño. Conclusiones: No se realiza una adecuada búsqueda del SAOS en pacientes con un evento cardiovascular o cerebrovascular agudo. En los pocos pacientes en los que se sospecha esta patología no existe seguimiento clínico ni tampoco se ofrece opción diagnóstica ni terapéutica alguna. (Rev Med Hered 2006;17:148-155.
