    ELENA is a compact ring for cooling and further deceleration of 5.3 MeV antiprotons delivered by the CERN Antiproton Decelerator. The AD physics program is focused on trapping antiprotons in Penning traps where antihydrogen is formed after recombination with positrons. The ultimate physics goal is to perform spectroscopy on antihydrogen atoms at rest and to investigate the effect of the gravitational force on matter and antimatter.

    ELENA is a compact ring for cooling and further deceleration of 5.3 MeV antiprotons delivered by the CERN Antiproton Decelerator. The AD physics program is focused on trapping antiprotons in Penning traps where antihydrogen is formed after recombination with positrons. The ultimate physics goal is to perform spectroscopy on antihydrogen atoms at rest and to investigate the effect of the gravitational force on matter and antimatter. In today’s set-up, most (99.9%) of the antiprotons produced are lost due to the use ofdegrader foils needed to decelerate them from the AD ejection energy down to around 5 keV; an energy suitable for trapping. By using a ring equipped with beam cooling, high deceleration efficiency and an important increase in phase-space density can be obtained, resulting in an increased number of trapped antiprotons. For the ATRAP and ALPHA experiments, improvements of up to 2 orders of magnitude can be expected. The same holds for the AEGIS experiment which is currently b

    2010-01-01

    (Photo LAPP ) Marcel Vivargent died on 31 January of this year, aged 87. After obtaining a science degree in 1949, he joined the CNRS in 1951, starting out in the laboratory of Frédéric Joliot Curie at the Collège de France, and obtaining his doctorate in 1958. He worked on the installation of the cyclotron at the Radium Institute in Orsay, where he conducted research until 1960. That year he went to CERN, joining a small group of physicists to work on hadron production and kaon physics at the PS. Passionate about the future of the discipline in France, in the 1960s Marcel Vivargent worked together with Robert Lévy-Mandel and the physicists and engineers in Orsay and at Saclay on the design of a 45 GeV accelerator project, which never materialised. In 1968 he was appointed director of the high-energy division of the CNRS, bringing together particle physicists from IPN in Orsay and from the University of Paris Jussieu. In parallel, he participated in the experim...

  15. Marcel Duchamp and Alfred Jarry

    Pieter de Nijs

    2016-06-01

    Full Text Available Alfred Jarry (1873-1907 is usually presented as one of Marcel Duchamp’s literary examples. Duchamp however never explicitly named Jarry as such; unlike he did with Jules Laforgue, Raymond Roussel and Jean-Paul Brisset. The reason why Jarry is nevertheless often mentioned as one of Duchamp's major inspirations lies in some – mainly thematic –parallels between their works. Duchamp's ‘amusing physics’ (physique amusante seems to be directly inspired by the pataphysics Jarry introduced in Gestes et opinions du Docteur Faustroll, pataphysicien (1911. The fantastic machines Jarry staged in a novel like Le Surmâle (1902 and in the various stories he wrote for magazines such as La Revue blanche, La Plume and Le Canard sauvage have traces in common with the machineries Duchamp gave shape in - for example - his La Mariee mise à nu par ces célibataires, même. And Duchamp sometimes did refer directly to Jarry, for example to his famous 'merdre'.More interesting though then the thematic parallels are the linguistic experiments Jarry and Duchamp both ventured on, showing some striking similarities.

    2013-01-01

    The Extra Low ENergy Antiproton ring (ELENA) to be built at CERN is aimed at substantially increasing the number of antiprotons to the low energy antiproton physics community. It will be a small machine which will decelerate low intensity beams (<4x107) from 5.3 MeV to 100 keV and will be equipped with an electron cooler to avoid beam losses during the deceleration and to significantly reduce beam phase space at extraction. To measure the beam parameters from the extraction point of the Antiproton Decelerator (AD), through the ELENA ring and all the way to the experiments, many systems will be needed to ensure that the desired beam characteristics are obtained. Particular attention needs to be paid to the performance of the electron cooler which depends on reliable instrumentation in order to efficiently cool the antiprotons. This contribution will present the different monitors that have been proposed to measure the various beam parameters as well as some of the developments going on to further improve th...

    A nonlinear system of differential equations that models the bone marrow cellular kinetics associated with radiation injury, molecular repair, and compensatory cell proliferation has been extensively documented. Recently, that model has been implemented as MarCell, a user-friendly MS-DOS computer program that allows users with little knowledge of the original model to evaluate complex radiation exposure scenarios. The software allows modeling with the following radiations: tritium beta, 100 kVp X, 250 kVp X, 22 MV X, {sup 60}Co, {sup 137}Cs, 2 MeV electrons, triga neutrons, D-T neutrons, and 3 blends of mixed-field fission radiations. The possible cell lineages are stem, stroma, and leukemia/lymphoma, and the available species include mouse, rat, dog, sheep, swine, burro, and man. An attractive mathematical feature is that any protracted protocol can be expressed as an equivalent prompt dose for either the source used or for a reference, such as 250 kVp X rays or {sup 60}Co. Output from MarCell includes: risk of 30-day mortality; risk of cancer and leukemia based either on cytopenia or compensatory cell proliferation; cell survival plots as a function of time or dose; and 4-week recovery kinetics following treatment. In this article, the program`s applicability and ease of use are demonstrated by evaluating a medical total body irradiation protocol and a nuclear fallout scenario.

    AREVA is the world leader in the design and construction of nuclear power plants, the manufacture of heavy components, and the supply of nuclear fuel and nuclear services such as maintenance and inspection. The Equipment Division provides the widest range of nuclear components and equipment, manufactured at its two facilities in Jeumont, northern France, and St. Marcel, in Burgundy. The St. Marcel plant, set on 35 ha (87.5 acres) near Chalon-sur-Saone, was established in 1973 in a region with a long history of specialized metalworking and mechanical activities to meet the demand for non-military nuclear requirements in France. The site offers two advantages: - excellent facilities for loading and transporting heavy components on the Saone river, - it's proximity to other group sites. Since its completion in 1975, the Chalon/St. Marcel facility has manufactured all the heavy components for French pressurized water reactors (PWRs) ranging from 900 MW to 1500 MW. It has also completed a significant number of export contracts that have made AREVA world leader. Nearly 600 heavy components (reactor vessels, steam generators, pressurizers and closure heads) have been manufactured or are currently being manufactured since the plant opened in 1975. The plant is at the heart of the manufacturing chain for nuclear steam supply systems (NSSS) supplied by AREVA. On the basis of engineering data, the plant manufactures reactor vessels, reactor vessel internals, steam generators, pressurizers and related components such as accumulators, auxiliary heat exchangers and supporting elements. Vessel upper internals Other similar components such as reactor vessels for boiling water reactors (BWR) or high temperature reactors (HTR) and other types of steam generators can also be manufactured in the plant (for example Once Through Steam Generators - OTSG). The basic activities performed at Chalon/St. Marcel are metalworking and heavy machining. These activities are carried out in

    This paper describes the new Antiproton Decelerator (AD) orbit measurement system and the Extra Low ENergy Antiproton ring (ELENA) orbit, trajectory and intensity measurement system. The AD machine at European Organization for Nuclear Research (CERN) is presently being used to decelerate antiprotons from 3.57 GeV/c to 100 MeV/c for matter vs anti-matter comparative studies. The ELENA machine, presently under commissioning, has been designed to provide an extra deceleration stage down to 13.7 MeV/c. The AD orbit system is based on 32 horizontal and 27 vertical electrostatic Beam Position Monitor (BPM) fitted with existing low noise front-end amplifiers while the ELENA system consists of 24 \\gls{BPM}s equipped with new low-noise head amplifiers. In both systems the front-end amplifiers generate a difference (delta) and a sum (sigma) signal which are sent to the digital acquisition system, placed tens of meters away from the AD or ELENA rings, where they are digitized and further processed. The beam position is calculated by dividing the difference signal by the sum signal either using directly the raw digitized data for measuring the turn-by-turn trajectory in the ELENA system or after down-mixing the signals to baseband for the orbit measurement in both machines. The digitized sigma signal will be used in the ELENA system to calculate the bunched beam intensity and the Schottky parameters with coasting beam after passing through different signal processing chain. The digital acquisition arrangement for both systems is based on the same hardware, also used in the ELENA Low Level Radio Frequency (LLRF) system, which follows the VME Switched Serial (VXS) enhancement of the Versa Module Eurocard 64x extension (VME64x) standard and includes VITA 57 standard Field Programmable Gate Array Mezzanine Card (FMC).

    The renewable energy issue opens the door to an ambient of opportunities. Santa Elena, one of the coastal provinces of Ecuador has the chance to go from a fossil fuel energy culture to a new energy scheme based on the use of environmental friendly fuels like natural gas and other renewable energy carriers like hydrogen. The marginal production of oil and natural gas from the Gustavo Galindo Velasco field and the updated gas reserves from the Gulf of Guayaquil make it possible. Infrastructure for natural gas production and distribution for vehicles is almost ready and any of the three refineries can generate hydrogen from natural gas. This provides the opportunity to reshape the Santa Elena transport energy matrix, where vehicles can burn natural gas and inter country buses can work with hydrogen. Traditional Fishing boats can be fitted with hydrogen storage and fuel systems later on. Santa Elena should face this challenge through a joint effort of public and private parties. Santa Elena State University and its partners as a focus point to create: The Campus of Energy Knowledge, where research, science and technology will serve companies that work in the energy business with a strong synergy, which will create jobs for the Santa Elena people.

    In 2011 the ELENA decelerator was approved as a CERN project. Initially one extraction was foreseen, which should use a kicker and a magnetic septum which can be recuperated from an earlier installation. Since then a second extraction has been approved and a new solution was studied using only electric fields to extract the beam. This will be achieved by fast pulsing a separator, allowing single-bunch but also a full single-turn extraction from ELENA towards the experiments. The extraction and transfer requirements of ELENA are described, followed by the principal differences between the magnetic and electric field concepts. The design of electrostatic focussing and bending devices for the transfer lines will be presented. Finally the field quality which can be achieved with the separator and the concept of its power supply will be discussed.

  1. ELENA prepares a bright future for antimatter research

    CERN Bulletin

    2011-01-01

    At its recent session in June, the CERN Council approved the construction of the Extra Low ENergy Antiproton ring (ELENA) – an upgrade of the existing Antiproton Decelerator. ELENA will allow the further deceleration of antiprotons, resulting in an increased number of particles trapped downstream in the experimental set-ups. This will give an important boost to antimatter research in the years to come.   Layout of the AD experimental hall: the Antiproton Decelerator ring (purple); the ALPHA, ASACUSA, and ATRAP experiments (green); the ACE experiment (not pictured); and the new ELENA ring (blue). The Antiproton Decelerator (AD) is CERN’s widely recognized facility for the study of antimatter properties. The recent successes of the AD experiments are just the latest in a long list of important scientific results that started with LEAR (Low Energy Antiproton Ring). The scientific demand for low-energy antiprotons at the AD continues to grow. There are now four experiments runnin...

    Full Text Available Marcel Duchamp made his first readymade over a century ago: a deceptively simple gesture that would turn the art world upside down. The core of artistic practise no longer lies in creating, but in selecting and displaying. But selecting and displaying are also the core tasks of the independent curator. Duchamp already proved in the 1930’s how powerful an exhibition maker can be. A power struggle arose: who gives meaning to art, the curator or the artist?

    Full Text Available No ‘visual’ artist addressed the sense of smell as often as Marcel Duchamp did. Whereas his solid objects can still be studied visually and textually, the scents he used have by now evaporated, and a vocabulary to describe them is lacking until today. What we have left are nose witness reports and the possibility to smell olfactory reconstructions. Rereading canonical text with a more sensory gaze and inhaling these historical fragrances, such as cedar, erotic perfumes and coffee,  will enable us to reconstruct the olfactory dimension of our highly ocularcentric history of art.

    Full Text Available Passado um século, será que a definição de prece que Marcel Mauss nos ofereceu lança ainda sugestões analíticas válidas? Para ele, a questão central era compreender a passagem da fala à imposição: isto é, por que respondem os deuses? Parece-nos que, seguindo alguns autores contemporâneos, tanto na área da filosofia como da comunicação animal, é possível avançar um pouco mais na via aberta que o grande sociólogo nos deixou no dia em que desistiu do que todos à época esperavam ser sua obra mestra.One hundred years later, does Marcel Mauss's definition of prayer still provide us with useful analytical suggestions? In his opinion, the central question to answer was how does one pass from speaking to demanding: that is, why do the gods respond? In this paper, inspired by contemporary debates in philosophy and animal communication, we propose that it is possible today to advance a little further in the door left open by the father of sociology when he finally decided to give up on the work that his contemporaries hoped would be his greatest.

However, this is a false perspective.

  12. Consciousness, art, and the brain: lessons from Marcel Proust.

    Science.gov (United States)

    Epstein, Russell

    2004-06-01

    In his novel Remembrance of Things Past, Marcel Proust argues that conventional descriptions of the phenomenology of consciousness are incomplete because they focus too much on the highly-salient sensory information that dominates each moment of awareness and ignore the network of associations that lies in the background. In this paper, I explicate Proust's theory of conscious experience and show how it leads him directly to a theory of aesthetic perception. Proust's division of awareness into two components roughly corresponds to William James' division of the stream of thought into a "nucleus" and "fringe." Proust argues that the function of art is to evoke the underlying associative network indirectly in the mind of the observer by using carefully chosen sensory surfaces to control the stream of thought. I propose a possible neural basis for this Proustian/Jamesian phenomenology, and argue that the general principles of Proustian aesthetics can be applied to all forms of art. I conclude that a scientific theory of art should follow in a straightforward manner from a scientific theory of consciousness.

    This Report gives a full description of the ELENA Ring to be built within the circumference of the Antiproton Decelarator (AD) Ring, in Building 193 at CERN. The ELENA ring will further decelerate the antiprotons coming from the AD at the momentum of 100 MeV/c down to 13.7 MeV/c, which corresponds to the kinetic energy of 100 keV before extracting to the physics experiments in the same building. The history of such an extra low energy antiproton ring at CERN goes a long way back, and even to the Decelerator’s previous incarnation, the Low Energy Antiproton Ring (LEAR), which came into operation in 1983. Already at that time, there were physics’ requests to further decelerate the antiprotons expected from LEAR by proposals for ELENA. Appendix I illustrates the cover pages of two such CERN documents from 1982.

    The Antiproton Decelerator (AD) complex at CERN will be extended by an extra low energy anti-proton ring (ELENA) [1] further decelerating the anti-protons thus improving their trapping. The kinetic energy of 100 keV at ELENA extraction facilitates the use of electrostatic transfer lines to the experiments. The mechanical implementation of the electrostatic devices are presented with focus on their alignment, bakeout compatibility, ultra-high vacuum compatibility and polarity switching. Field optimisations for an electrostatic crossing device of three beam lines are shown.

    Broad Absorption Lines (BALs) are present in the spectra of ~20% of quasars (QSOs), indicating the presence of fast outflows (up to 0.2c) intercepting the observer's line of sight. Radio-Loud (RL) BAL QSOs are even more rare, being four times less common than Radio-Quiet (RQ) BAL QSOs. The reason for that is still not clear, leaving open questions about the nature of the BAL-producing outflows and their connection with the radio jet. We explored the spectroscopic characteristics of RL and RQ BAL QSOs, aiming at finding a possible explanation for the rarity of the former. We identified two samples of genuine BAL QSOs from SDSS optical spectra, one RL and one RQ, in a suitable redshift interval (2.5< z <3.5) that allowed us to observe the Mg II and H$\\beta$ emission lines in the adjacent Near-Infrared (NIR) band. We collected NIR spectra of the two samples using the Telescopio Nazionale Galileo (TNG, Canary Islands). Using relations known in the literature, we could estimate black hole mass, broad line re...

  7. BAL QSOs and Extreme UFOs: The Eddington Connection

    Science.gov (United States)

    Zubovas, Kastytis; King, Andrew

    2013-05-01

    We suggest a common physical origin connecting the fast, highly ionized winds (UFOs) seen in nearby active galactic nuclei (AGNs), and the slower and less ionized winds of broad absorption line (BAL) QSOs. The primary difference is the mass-loss rate in the wind, which is ultimately determined by the rate at which mass is fed toward the central supermassive black hole (SMBH) on large scales. This is below the Eddington accretion rate in most UFOs, and slightly super-Eddington in extreme UFOs such as PG1211+143, but ranges up to ~10-50 times this in BAL QSOs. For UFOs this implies black hole accretion rates and wind mass-loss rates which are at most comparable to Eddington, giving fast, highly ionized winds. In contrast, BAL QSO black holes have mildly super-Eddington accretion rates, and drive winds whose mass-loss rates are significantly super-Eddington, and so are slower and less ionized. This picture correctly predicts the velocities and ionization states of the observed winds, including the recently discovered one in SDSS J1106+1939. We suggest that luminous AGNs may evolve through a sequence from BAL QSO through LoBAL to UFO-producing Seyfert or quasar as their Eddington factors drop during the decay of a bright accretion event. LoBALs correspond to a short-lived stage in which the AGN radiation pressure largely evacuates the ionization cone, but before the large-scale accretion rate has dropped to the Eddington value. We show that sub-Eddington wind rates would produce an M-σ relation lying above that observed. We conclude that significant SMBH mass growth must occur in super-Eddington phases, either as BAL QSOs, extreme UFOs, or obscured from direct observation.

Si les ouvrages ethnologiques publiés par Griaule ou par ses collègues sont le fruit d’une sélection et d’une organisation de leurs données à des fins de démonstration scientifique, les notes de terrain, en amont, contiennent en revanche une multitude d’informations variées et inédites que des anthropologues maliens – familiers des lieux et de la langue – peuvent facilement contextualiser et interpréter grâce aux annotations personnelles ou aux citations inscrites sur les fiches ou sur les carnets.

    2014-01-01

    Broad absorption line (BAL) quasars have been studied for over thirty years. Yet it is still unclear why and when we observe broad absorption lines in quasars. Is this phenomenon caused by geometry or is it connected with the evolution process? Variability of the BAL quasars, if present, can give us information about their orientation, namely it can indicate whether they are oriented more pole-on. Using the Torun 32-metre dish equipped with the One Centimetre Receiver Array (OCRA) we have started a monitoring campaign of a sample of compact radio-loud BAL quasars. This 30 GHz variability monitoring program supplements the high-resolution interferometric observations of these objects we have carried out with the EVN and VLBA.

    Abstract (E: This paper examines Woman Ajar (1985, a late, largely forgotten photo book by Marcel Mariën, one of the key figures of Belgian post war surrealism. Representing the female body as fragmented and alienated by small objects, Mariën’s photographs balance between the private (amateurish and the public (professional and explores the fragile border between art and pornography. In addition, there is a sense of belatedness in them, which makes them particularly hard to label. This paper proposes the concept of minor photography, borrowed from Gilles Deleuze and Felix Guattari’s concept of a minor literature, as a valuable tool to approach Marcel Mariën’s work, which risks slipping through art history’s net.

    The issue of the introduction of viennese "scientific philosophy" in France appears to be resolved. However, the rediscovery of the positivist physicist Marcel Boll (1886-1971), who was the first-well before Louis Rougier-to draw the French public's attention to the works of Schlick, Frank, and Carnap, obliges us to rethink the passage from traditional positivism to neo-positivism during the 1920s and 1930s. The French reception of the Vienna circle can be dated earlier than accepted and is more profound than usualy assumed.

    2016-12-01

    Full Text Available Combining art historical and technical perspectives, this paper examines Richard Hamilton’s 1965–6 reconstruction of Marcel Duchamp’s Large Glass and the wider repercussions that Hamilton’s actions have had on our understanding of replication and the idea of authorship. The dramatic history of the work is unpacked thoroughly and provides a platform for thinking about the precariousness of materials and meanings, and the slippages that occur when replicas become part of the story of a work, an artist and an institution.

  18. BAL Quasars without intrinsic X-ray absorption

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    @@ While observing a sample of quasars with broad absorption line (BAL) in their spectra, Prof. WANG Junxian and his colleagues Prof. WANG Tinggui and Dr. ZHOU Hongyan with the Center for Astrophysics at the University of Science and Technology of China (USTC) discovered that unlike most of BAL quasars, two of the observed do not show intrinsic X-ray absorption, indicating a different composition of matter in their outflows. This might help us better understand how black holes devour and project gases, according to the astronomers.

    Microchannel Plates (MCP) detectors are frequently used in space instrumentation for detecting a wide range of radiation and particles. In particular, the capability to detect non-thermal low energy neutral species is crucial for the sensor ELENA (Emitted Low-Energy Neutral Atoms), part of the package SERENA (Search for Exospheric Refilling and Emitted Natural Abundances) on board the BepiColombo mission of ESA to Mercury to be launched in 2015. ELENA is a Time of Flight (TOF) sensor, based on a novel concept using an ultra-sonic oscillating shutter (Start section), which is operated at frequencies up to 50 kHz; a MCP detector is used as a Stop detector. The scientific objective of ELENA is to detect energetic neutral atoms in the range 10 eV - 5 keV, within 76° FOV, perpendicular to the S/C orbital plane. ELENA will monitor the emission of neutral atoms from the whole surface of Mercury thanks to the spacecraft motion. The major scientific objectives are the interaction between the plasma environment and the planet’s surface, the global particle loss-rate and the remote sensing of the surface properties. In particular, surface release processes are investigated by identifying particles released from the surface, via solar wind-induced ion sputtering (MEFISTO facility of the Physical Institute of the University of Bern (CH), measurements on three different types of MCP (with and without coating) have been performed providing the detection efficiencies in the energy range 10eV - 1keV. Outcomes from such measurements are discussed here.

    In this work, wurtzite BAlN layers with boron composition as high as 12% were successfully grown by MOVPE. The growth was performed at 650 C and then annealed at 1020 C. Low temperature growth was used in order to alleviate B-rich phase poisoning under high TEB/III ratio. The growth was performed by continuous epitaxy as well as by flow-modulate epitaxy. BAlN single layers with clearly defined X-ray diffraction peaks were achieved on AlN templates which are appropriate substrates for deep UV devices, as well as on GaN templates to facilitate distinguishing of the XRD peak of BAlN from the substrate peak. The layer demonstrated columnar crystalline features and inherited wurtzite structure from substrates.

    2016-01-01

    While narrow absorption lines (NALs) are relatively stable, broad absorption lines (BALs) and mini-BAL systems usually show violent time variability within a few years via a mechanism that is not yet understood. In this study, we examine variable ionization state (VIS) scenario as a plausible mechanism, as previously suspected. Over three years, we performed photometric monitoring observations of four mini-BAL and five NAL quasars at $z_{\\rm em}$ $\\sim$ 2.0 - 3.1 using the 105 cm Kiso Schmidt Telescope in $u$, $g$, and $i$-bands. We also performed spectroscopic monitoring observation of one of our mini-BAL quasar (HS1603+3820) using the 188-cm Okayama Telescope over the same period as the photometric observations. Our main results are as follows: (1) Structure function (SF) analysis revealed that the quasar UV flux variability over three years was not large enough to support the VIS scenario, unless the ionization condition of outflow gas is very low. (2) There was no crucial difference between the SFs of min...

  8. Il fascino del regresso Note su L’amica geniale di Elena Ferrante

    Directory of Open Access Journals (Sweden)

    Elisa Gambaro

    2014-12-01

    Full Text Available La corposa tetralogia L’amica geniale di Elena Ferrante contamina i moduli del Familienroman, del romanzo di formazione e della narrazione di indole storico-sociale. Il gioco di specchi tra i di- vergenti destini delle due protagoniste dà vita ad un congegno narrativo che corrode e mette sottilmente in dubbio il diagramma progressivo dell'emancipazione sociale e personale di Elena. Sull’onda della delusione storica e del fallimento delle utopie di una generazione, a prevalere è infine il fascino regressivo del ritorno alle origini del materno e alla vischiosità claustrofobica di una Napoli popolare senza speranza di riscatto. My Brilliant Friend, Elena Ferrante’s intense tetralogy presents a cross-fertilazation of Familienroman, Bildungsroman and historico-social narrative. The divergent destinies of the two female protagonists, which Ferrante conveys through mirror effects, generate a narrative ‘machine’ that destroys and questions the very narrative of the protagonist Elena’s social and personal emancipation and progress. The disillusion with history, the failure of the utopia of a whole generation are the hallmark of Ferrante’s latest work, which is therefore dominated by the regressive lure of the return to the maternal and to the claustophobic stickiness of a working-class Naples, where no redemption is possible.

    The CERN Extra Low ENergy Antiproton (ELENA) Ring is a new synchrotron that will be commissioned in 2016 to further decelerate the antiprotons coming from CERN’s Antiproton Decelerator (AD). Required longitudinal diagnostics include the intensity measurement for bunched and debunched beam and the measurement of Dp/p to assess the electron cooling performance. A novel method for the calculation of these parameters is proposed for ELENA, where signals from the twenty electrostatic Pick-Ups (PU) used for orbit measurements will be combined to improve the signal-to-noise ratio. This requires that the signals be digitally down-converted, rotated and summed so that the many electrostatic PUs will function as a single, distributed PU from the processing system viewpoint. This method includes some challenges and will not be used as the baseline longitudinal diagnostics for the initial ELENA operation. This paper gives an overview of the hardware and digital signal processing involved, as well as of the challenges t...

  11. The Creative Transformation of Trauma: Marcel Proust's in search of lost time.

    Science.gov (United States)

    Blum, Harold P

    2012-10-01

    Hidden childhood trauma beneath poignant memories is a central aspect of In Search of Lost Time. Marcel Proust's magnum opus may be psychoanalytically understood as an extraordinary literary transformation of severe trauma and associated unconscious confiicts. Proust's nearly fatal childhood asthma and concomitant medical mistreatment contributed to an intense ambivalent bond and bondage with his mother, replicated in the ambivalent relationships depicted in his novel. The retrieved and re-created past is relived in the novel's fantasy playground of time and space. Proust's intuitive grasp of signiflcant aspects of time, memory, trauma, and transference was consistent with psychoanalytic thought. In the vast novel, the narcissistic mortiflcation and losses of the protagonist are mourned, worked through, and partially redeemed. I interpret the famed joyous tasting of the madeleine in tea as an artfully disguised, temporally displaced, and affective reversal of life-threatening trauma. This article probes the role of Proust's intractable asthma in his breathless journey to ego mastery and timeless creativity.

    Marcel Proust was one of the greatest French writers of all times. Since early in his life, Proust was interested in arts and particularly literature. He also demonstrated a great knowledge of medicine, particularly neurology. His father was a doctor, and contributed to neurology through studies on aphasia, stroke, hysteria, and neurasthenia. During his childhood, Proust had the first asthma attack, initially considered a manifestation of neurasthenia. Regarding his illness, Proust was in touch with several renowned neurologists, such as Brissaud, Babinski and Sollier, and other disciples of Charcot. Proust spent the last three years of his life mostly confined to his bedroom since his health had badly deteriorated. In one moment, Babinski was called, examined Proust and after leaving his bedroom, announced to his brother that Proust was practically dead. Few hours later, Proust developed vomica and died.

  14. Art fighting its way back to aesthetics: Revisiting Marcel Duchamp’s Fountain

    Directory of Open Access Journals (Sweden)

    Anne Sejten

    2016-12-01

    Full Text Available When Claire Farago and Donald Preziosi claim that ‘art is not what you think it is,’ aesthetics itself is implicitly challenged, especially aesthetics’ seemingly inherent correlation with art. However, aesthetics, as complex and ambiguous as the concept of art, calls for a similar suspicion. In this essay, ‘Aesthetics is not what you think it is’ is thus an invitation to break through at the very point in which contemporary art seems to state the opposite—that art no longer should be a concern of aesthetics. The iconic example of Marcel Duchamp’s readymade, Fountain, which writes art history at the threshold of contemporary art, is summoned, on the contrary, to give evidence of an intact, though profoundly transformed, aesthetic engagement by the artist.

  15. Constraining FeLoBAL outflows from absorption line variability

    McGraw, S M; Hamann, F W; Capellupo, D M; Gallagher, S C; Brandt, W N

    2015-01-01

    FeLoBALs are a rare class of quasar outflows with low-ionization broad absorption lines (BALs), large column densities, and potentially large kinetic energies that might be important for `feedback' to galaxy evolution. In order to probe the physical properties of these outflows, we conducted a multiple-epoch, absorption line variability study of 12 FeLoBAL quasars spanning a redshift range between 0.7 and 1.9 over rest frame time-scales of approximately 10 d to 7.6 yr. We detect absorption line variability with greater than 8 sigma confidence in 3 out of the 12 sources in our sample over time-scales of 0.6 to 7.6 yr. Variable wavelength intervals are associated with ground and excited state Fe II multiplets, the Mg II 2796, 2803 doublet, Mg I 2852, and excited state Ni II multiplets. The observed variability along with evidence of saturation in the absorption lines favors transverse motions of gas across the line of sight (LOS) as the preferred scenario, and allows us to constrain the outflow distance from th...

  16. BAL QSOs and Extreme UFOs: the Eddington connection

    CERN Document Server

    Zubovas, Kastytis

    2013-01-01

    We suggest a common physical origin connecting the fast, highly ionized winds (UFOs) seen in nearby AGN, and the slower and less ionized winds of BAL QSOs. The primary difference is the mass loss rate in the wind, which is ultimately determined by the rate at which mass is fed towards the central supermassive black hole (SMBH) on large scales. This is below the Eddington accretion rate in most UFOs, and slightly super-Eddington in extreme UFOs such as PG1211+143, but ranges up to $\\sim 10-50$ times this in BAL QSOs. For UFOs this implies black hole accretion rates and wind mass loss rates which are at most comparable to Eddington, giving fast, highly-ionized winds. In contrast BAL QSO black holes have mildly super-Eddington accretion rates, and drive winds whose mass loss rates are significantly super-Eddington, and so are slower and less ionized. This picture correctly predicts the velocities and ionization states of the observed winds, including the recently-discovered one in SDSS J1106+1939. We suggest tha...

    Full Text Available One of the most singular characteristics of peronism is the originality of holding within it a double charismatic leadership complementary to each other. The quintessential paradigm corresponds to Perón and Eva Perón, but there were other cases, more modest, that have served to cement the argentine political culture: the marriage at power. Those first ladies redefined its role, and built spaces of power and influence in government. In this paper I analyze the role of Elena Caporale de Mercante and her new political role as wife of the most important governor who had the first Peronist government.

    At the last LEAP conference in Vancouver 2011 the authors stated that a project ”ELENA”, as an abbreviation for Extra Low ENergy Antiproton ring and as first discussed in 1982 for LEAR by H. Herr et al., was freshly proposed with a substantial new design and revised layout and that it was under consideration to be built at CERN. ELENA is an upgrade of the Anti-proton Decelerator (AD) at CERN and is devoted to special experiments with physics using low energy anti-protons. The main topics are the anti-hydrogen production and consecutive studies of the features of this anti-matter atom as well as the anti-proton nucleon interaction by testing the QED to high precision. During the last years the project underwent several steps in presentations at different committees at CERN and was finally approved such that the construction has started. ELENA will increase the number of useful anti-protons by about two orders of magnitude and will allow to serve up to four experiments simultaneously. Very first and convinc...

There are similarities and differences between that process of characterisation or subjectivisation Encarnación Aragoneses Urquijo (1885-1952 went through in order to become the famous writer Elena Fortún and the other process of characterisation that occupied her, a process of creating a narrative of a frustrated writing self, that of Celia. As a female writer who achieves successful authorial recognition late in life through a character that explores the contradictions and paradoxes the arrival of this late subjectivity caused in the author, Elena Fortún illuminates the implications of the intellectual problematisation of “la mujer nueva” during the first third of the last century.

  9. La filosofía de Marcel: del idealismo al realismo, del realismo a la filosofía concreta

    Directory of Open Access Journals (Sweden)

    Julia Urabayen

    2016-10-01

    Full Text Available En estas páginas se reflexiona acerca del significado del pensamiento de Marcel para delimitar qué es la filosofia concreta. Se incide en su formación neoidealista y su contacto con Bergson, que le conduce a una crítica del pensamiento sistemático que se agudiza tras la Primera Guerra Mundial. En segundo lugar, se produce un acercamiento al realismo, pero aparece un punto de desavenencia: para Marcel el ser está más allá del juicio predicativo. De ahí que opte por una filosofía existencial basada en dualismos y que se desarrolla como una serie de acercamientos al ser y no como una ontología.

    Purpose Sarcoidosis is a non-caseating granulomatous disease for which a role for infectious antigens continues to strengthen. Recent studies have reported molecular evidence of mycobacteria or propionibacteria. We assessed for immune responses against mycobacterial and propionibacterial antigens in sarcoidosis bronchoalveolar lavage (BAL) using flow cytometry, and localized signals consistent with microbial antigens with sarcoidosis specimens, using matrix-assisted laser desorption ionization imaging mass spectrometry (MALDI-IMS). Methods BAL cells from 27 sarcoidosis, 14 PPD- controls, and 9 subjects with nontuberculosis mycobacterial (NTM) infections were analyzed for production of IFN-γ after stimulation with mycobacterial ESAT-6 and Propionibacterium acnes proteins. To complement the immunological data, MALDI-IMS was performed to localize ESAT-6 and Propionibacterium acnes signals within sarcoidosis and control specimens. Results CD4+ immunologic analysis for mycobacteria was positive in 17/27 sarcoidosis subjects, compared to 2/14 PPD-subjects, and 5/9 NTM subjects (p=00.008 and p=00.71 respectively, Fisher's exact test). There was no significant difference for recognition of P. acnes, which occurred only in sarcoidosis subjects that also recognized ESAT-6. Similar results were also observed for the CD8+ immunologic analysis. MALDI-IMS localized signals consistent with ESAT-6 only within sites of granulomatous inflammation, whereas P. acnes signals were distributed throughout the specimen. Conclusions MALDI-IMS localizes signals consistent with ESAT-6 to sarcoidosis granulomas, whereas no specific localization of P. acnes signals is detected. Immune responses against both mycobacterial and P. acnes are present within sarcoidosis BAL, but only mycobacterial signals are distinct from disease controls. These immunologic and molecular investigations support further investigation of the microbial community within sarcoidosis granulomas. PMID:22552860

  12. BAL QSOs and Extreme UFOs: the Eddington connection

    2013-01-01

    We suggest a common physical origin connecting the fast, highly ionized winds (UFOs) seen in nearby AGN, and the slower and less ionized winds of BAL QSOs. The primary difference is the mass loss rate in the wind, which is ultimately determined by the rate at which mass is fed towards the central supermassive black hole (SMBH) on large scales. This is below the Eddington accretion rate in most UFOs, and slightly super-Eddington in extreme UFOs such as PG1211+143, but ranges up to $\\sim 10-50$...

  13. A SCUBA-2 survey of FeLoBAL QSOs: Are FeLoBALs in a `transition phase' between ULIRGs and QSOs?

    It is thought that a class of broad absorption line (BAL) QSOs, characterised by Fe absorption features in their UV spectra (called `FeLoBALs'), could mark a transition stage between the end of an obscured starburst event and a youthful QSO beginning to shed its dust cocoon, where Fe has been injected into the interstellar medium by the starburst. To test this hypothesis we have undertaken deep SCUBA-2 850 $\\mu$m observations of a sample of 17 FeLoBAL QSOs with 0.89 $\\leq$ z $\\leq$ 2.78 and -23.31 $\\leq$ M$_{B}$ $\\leq$-28.50 to directly detect an excess in the thermal emission of the dust which would probe enhanced star-formation activity. We find that FeLoBALs are not luminous sources in the submillimetre, none of them are individually detected at 850 $\\mu$m, nor as a population through stacking ($F_{s}=1.14\\pm0.58$ mJy). Statistical and survival analyses reveal that FeLoBALs have sub-mm properties consistent with BAL and non-BAL QSOs with matched redshifts and magnitudes. An SED fitting analysis shows that ...

  15. When Marcel Mauss's Essai sur le Don becomes The Gift: variations on the theme of solidarity.

    Science.gov (United States)

    Bateman, Simone

    2016-12-01

    Since the early 1970s, Marcel Mauss's Essai sur le Don (1923), translated into English as The Gift in 1954, has been a standard reference in the social science and bioethical literature on the use of human body parts and substances for medical and research purposes. At that time, three social scientists-political scientist Richard Titmuss in the United Kingdom and sociologist Renée C. Fox working with historian Judith Swazey in the United States-had the idea of using this concept to highlight the fundamental structure of the biomedical practices they were studying, respectively, blood donation, and hemodialysis and organ transplantation. The fact that these first applications of Mauss's essay should emerge in English- rather than in French-speaking countries raises the question of what the translation of the essay, and notably of the word don as gift, may have to do with this fact. Reading Mauss in translation undoubtedly inspired a seminal approach to interpreting medical and research practices based on bodily giving. This article posits that something may have also been lost: a much broader concept of giving with unquestionable links to the Durkheimian concept of solidarity, which Mauss conceptualizes not only as an obligation but also as a liberty to give.

    Full Text Available Considering contemporary Anthropology’s debate around photography, there is a keen interest in the understanding of one of the most important open to public consultation photographic collections on 20th Century Brazil, that of Frenchman Marcel Gautherot (1910- 1996. The collection comprises around 25,000 photographs, purchased in 1999 by Instituto Moreira Salles and kept in its fund in the city of Rio de Janeiro. The text comments on the photographer’s work, linked to documentary projects under the patronage of institutions such as the Musée de l´Homme in Paris, at the end of the 1930s, and both the National Historic and Artistic Patrimony Service and the Brazilian Folklore Defence Campaign, in Brazil, between the years of 1940 -1960. Such commitments and interests define important thematic groupings in the production and organisation of his personal photographic archive. A discussion about criteria and technical procedures adopted by the photographer is attempted, detailing series and visual narratives about Brazilian culture’s density. With the photographs’ purchase by the IMS, the oeuvre’s aesthetic quality, now as an institutional collection, is highlighted. The collection’s manners of preservation and conservation, reproduction and circulation are redefined.

  17. Marcel Duchamp: on the fruitful use of narcissism and destructiveness in contemporary art.

    Science.gov (United States)

    Abella, Adela

    2007-08-01

    Considering Marcel Duchamp's work, this paper raises the question as to the nature of the subjective experience proposed by contemporary art to today's audience. Approaching art through the concept of sublimation, Freud maintains a fundamentally optimistic and positive view, putting forward its libidinal and sexual aspects, the pursuit of pleasure, beauty, and omnipotence. Following the path opened by Freud through the concept of the 'uncanny', most post-Freudian authors have proposed a 'blacker' image of artistic endeavour, allowing the expression of aggression. From a perspective which is neither that of an art historian nor a moralist, the author proposes the idea that certain propositions of contemporary art may allow the viewer to live narcissistic and destructive fantasies, via culturally sanctioned and socially acceptable means. The recognition of the fertile use of destruction as a condition of the emergence of the new, on the one hand, as well as the legitimacy of the expression through art of the most primitive fantasies and the right to non-communication, on the other, are postulated as constructs for a non-normative, non-judgemental psychoanalytic approach to the cultural world.

  18. Broadband nuclear emission in two radio-loud BAL quasars

    CERN Document Server

    Kunert-Bajraszewska, M; Janiuk, A

    2014-01-01

    The X-ray weakness of broad absorption line (BAL) quasars in comparison to non-BAL objects is possibly caused by the absorption of X-ray emission by the shielding material near the equatorial plane. On the other hand, the radio-loud BALQSOs are more X-ray loud than the radio-quiet ones. This suggests that part of the X-ray emission may arise from the radio jet. To investigate this possibility, we modelled the nuclear spectra of two radio-loud BALQSOs. We focus on the emission from the very centres of these two objects. The source of emission was approximated by a single, homogeneous component that produces synchrotron and inverse-Compton (IC) radiation. The simplicity of the model allowed us to estimate the basic physical parameters of the emitting regions, using a universal analytic approach. Such methods have already been used in blazars. For the first time we propose this solution for quasars. In addition, we modelled the radiation spectra of the accretion disk and its corona to compare them with the jets'...

  4. Broad absorption line (BAL) quasars as a class of low luminosity AGNs

    CERN Document Server

    Kunert-Bajraszewska, M; Roskowinski, C; Gawronski, M

    2015-01-01

    Broad absorption lines seen in some quasars prove the existence of ionized plasma outflows from the accretion disk. Outflows together with powerful jets are important feedback processes. Understanding physics behind BAL outflows might be a key to comprehend Galaxy Evolution as a whole. First radio-loud BAL quasar was discovered in 1997 and this discovery has opened new possibilities for studies of the BAL phenomena, this time on the basis of radio emission. However, information about the radio structures, orientation and age of BAL quasars is still very limited due to weak radio emission and small sizes of these objects. Our high-resolution radio survey of a sample of BAL quasars aims to increase our knowledge about these objects. In this article, we present some conclusions arising from our research.

    A large-scale ecosystem manipulation (Spruce and Peatland Responses under Climatic and Environmental Change, SPRUCE) is being constructed in the Marcell Experimental Forest, Minnesota, USA, to determine the effects of climatic forcing on ecosystem processes in northern peatlands. Prior to the initiation of the manipulation, we characterized the solid-phase peat to a depth of 2 meters using a variety of techniques, including peat C:N ratios, 13C and 15N isotopic composition, Fourier Transform Infrared (FT IR), and 13C Nuclear Magnetic Resonance spectroscopy (13C NMR). FT IR determined peat humification-levels increased rapidly between and 75 cm, indicating a highly reactive zone. We observed a rapid drop in the abundance of O-alkyl-C, carboxyl-C, and other oxygenated functionalities within this zone and a concomitant increase in the abundance of alkyl- and nitrogen-containing compounds. Below 75-cm, minimal change was observed except that aromatic functionalities accumulated with depth. Incubation studies revealed the highest methane production rates and greatest CH4:CO2 ratios within this and 75 cm zone. Hydrology and surface vegetation played a role in belowground carbon cycling. Radiocarbon signatures of microbial respiration products in deeper porewaters resembled the signatures of dissolved organic carbon rather than solid phase peat, indicating that more recently photosynthesized organic matter fueled the bulk of subsurface microbial respiration. Oxygen-containing functionalities, especially O-alkyl-C, appear to serve as an excellent proxy for soil decomposition rate, and in addition should be a sensitive indicator of the response of the solid phase peat to the climatic manipulation.

  12. Geology of the Santa Elena Peninsula, Costa Rica and its implications for the tectonic evolution of the Central America-Caribbean region

    Energy Technology Data Exchange (ETDEWEB)

    Lew, L.R.

    1985-01-01

    The Santa Elena Peninsula of Costa Rice represents an Aptian to Middle Eocene intraoceanic volcanic arc formed on a basement of serpentinized periodotite. This peridotite was probably part of the oceanic lithosphere formed at a spreading ridge which began to separate South America from North America in pre-Jurassic time. The arc resulted from northward subduction of oceanic crust along one ENE-trending trench about 70 km south of Santa Elena. The first phase of tectonism, arc volcanism, and sedimentation occurred in the area from Aptian to Campanian time. Carbonate bank limestone were deposited on the peridotite, which had been tilted and uplifted along E-W-trending high angle faults. A second volcanic arc developed above the limestone and was active until the Middle Eocene. From the Campanian to the Middle Eocene a forearc basin evolved south of the arc and a backarc basin north of it. A major Middle Eocene tectonic episode was associated with termination of activity of the Santa Elena subduction zone. This involved both thin-skinned deformation and reactivation of the steep basement faults to juxtapose peridotite and Campanian to Middle Eocene sediments. Existing models of the early plate tectonic evolution of the region, postulating initiation of spreading in the Jurassic, and development of a major transform in the Santa Elena area in the Cretaceous, are incompatible with the geology of the Santa Elena area. New models have been formulated genetically relating the structures in the Santa Elena tectonic province to northward subduction.

  13. Review of rest gas interaction at very low energies applied to the Extra Low Energy Antiproton ring ELENA

    CERN Document Server

    Carli, C; Karamyshev, O; Welsch, C P

    2014-01-01

    The Extremely Low ENergy Antiproton ring (ELENA) is a small synchrotron equipped with an electron cooler, which shall be constructed at CERN to decelerate antiprotons to energies as low as 100 keV. Scattering of beam particles on rest gas molecules may have a detrimental effect at such low energies and leads to stringent vacuum requirements. Within this contribution scattering of the stored beam on rest gas molecules is discussed for very low beam energies. It is important to carefully distinguish between antiprotons scattered out of the acceptance and lost, and those remaining inside the aperture to avoid overestimation of emittance blow-up. Furthermore, many antiprotons do not interact at all during the time they are stored in ELENA and hence this is not a multiple scattering process

    The Santa Elena Ophiolite in Costa Rica is composed of a well-preserved fragment of the lithospheric mantle that formed along a paleo-spreading center. Within its exposed architecture, this ophiolite records a deep section of the melt transport system of a slow/ultra-slow spreading environment, featuring a well-developed melt-focusing system of coalescent diabase dikes that intrude the peridotite in a sub-vertical and sub-parallel arrangement. Here we present an integrated analysis of new structural data, 40Ar/39Ar geochronology, major and trace element geochemistry and radiogenic isotope data from the diabase dikes in order to elucidate the tectonic setting of the Santa Elena Ophiolite. The dikes are basaltic and tholeiitic in composition. Petrological models of fractional crystallization suggest deep pressures of crystallization of > 0.4 GPa for most of the samples, which is in good agreement with similar calculations from slow/ultra-slow spreading ridges and require a relatively hydrated ( 0.5 wt.% H2O) MORB-like source composition. The diabase dikes share geochemical and isotope signatures with both slow/ultra-slow spreading ridges and back-arc basins and indicate mixing of a DMM source and an enriched mantle end-member like EMII. The 40Ar/39Ar geochronology yielded an age of 131 Ma for a previous pegmatitic gabbroic magmatic event that intruded the peridotite when it was hot and plastic and an age of 121 Ma for the diabase intrusions, constraining the cooling from near asthenospheric conditions to lithospheric mantle conditions to 10 Ma. Our findings suggest a complex interplay between oceanic basin and back-arc extension environments during the Santa Elena Ophiolite formation. We propose an alternative hypothesis for the origin of Santa Elena as an obducted fragment of an oceanic core complex (OCC).

  15. Origin of plagiogranites in oceanic complexes: A case study of the Nicoya and Santa Elena terranes, Costa Rica

    2016-10-01

    The origin of minor leucocratic intrusions known as "plagiogranites" in oceanic complexes dominated by basaltic compositions have been debated in the literature. Here we use well preserved plagiogranites within the contrasting Santa Elena Ophiolite and the Nicoya Complex, NW Costa Rica, to investigate the origin and age of these leucocratic intrusions. Magmatic zircons of plagiogranites of the Santa Elena ophiolite and the Nicoya Complex, yield weighted mean SHRIMP 206Pb/238U ages of 125.3 ± 2.0 Ma and 90.9 ± 2.0 Ma to 88.5 ± 2.0 Ma (n = 5), respectively. These ages record the main magmatic phases of formation of these intrusions preserved in each complex. Relatively flat, unfractionated chondrite-normalized REE patterns of plagiogranites from both complexes mimic signatures of related mafic rocks, which is consistent with formation via fractional crystallization from a mafic source as opposed to partial melting of a mafic (basalt, amphibolite) protolith. In the case of the Nicoya Complex, modelling suggests that the Nicoya plagiogranites are consistent as 10-15% residual liquids after fractional crystallization from its mafic parental source. Trace element systematics of the plagiogranites are consistent with an oceanic arc origin for Santa Elena and a mostly mid-ocean ridge to oceanic-plateau origin for Nicoya.

    Multi-frequency 1.7, 5 and 8.4-GHz VLBA observations of a radio-loud broad absorption line (BAL) quasar 1045+352 are presented. It is a young compact steep spectrum (CSS) object and its asymmetric, two-sided morphology on a scale of several hundred parsecs, extending in two different directions, may suggest intermittent activity. The young age and unusual morphology of 1045+352 are arguments in favour of an evolution scenario for BAL quasars, in which the BAL features appear at a very early stage of their evolution.

  19. ELENA GARRO, A DESHORA: FIGURAS LITERARIAS DE LA ABYECCIÓN

    Full Text Available The massacre of Tlatelolco in 1968 was the most bloody incident of Diaz Ordaz’s government in Mexico and promoted a severe process of persecution and repression of the student movement. One of its consequences was the suspicion of betrayal by Elena Garro of the movement’s intellectual authors. Since then, Garro embodied an abject character of collaboration, in constant harassment, leading to her exile during twenty years.This paper considers the implications of the accusation and the diagnosis of insanity that accompanies it. For some critics this insanity is redeemed in her literary work, which in this operation achieves prominence; but the insanity can be thought of as irreducible. Garro’s delirious gaze doesn’t sublimate the trauma, but repeats again and again the political violence, with harassed, exposed and out of place characters, in situations of daily totalitarianism. Figures of betrayal emerge in her histories, involving characters and knowledge outside the language of the official left (animal, children, women, the indigenous, marked by their helplessness and questioning the premises of political parties.

    The CERN Extra Low ENergy Antiproton (ELENA) Ring is a new synchrotron designed for cooling and further decelerating the 5.3 MeV antiprotons delivered by the CERN Antiproton Decelerator (AD). The ring is equipped with two magnetic pick-ups used for longitudinal beam diagnostics. These ultra low noise AC beam transformers consist of a doubly shielded, ferrite-loaded cavity with a ceramic gap in the beam pipe, a secondary winding to which an ultralow noise JFET head amplifier with feedback is connected. The JFET head amplifier is mounted close to the cavity and the AC beam transformers are covering respectively the 0.003-3MHz frequency range (low frequency type) and 0.8-30 MHz frequency range (high frequency type) [1]. The ferrite material used to couple primary and secondary in the beam transformer, has a key impact in the noise characteristics of the amplifier. For this reason a magnetic characterization of the selected ferrite rings has been carried out and is reported in the following.

    The synthesis of dilute B content BAlN and BGaN has been performed by an advanced MBE technique called ENABLE. ENABLE is a direct chemical activation approach to film growth which uses an energetic beam of neutral N atoms to activate nitride thin film growth. Using the ENABLE-MBE technology, up to 3.1% and 3.5% B has been incorporated in BAlN and BGaN, respectively. XRD scans indicate that the films are single phase and the crystalline quality is high. It has been shown in BAlN that a lower substrate temperature during growth leads to higher level of incorporation of B, with all other parameters held constant. Electrical measurements of BAlN shows reasonable breakdown voltage (∝25 V/μm) and leakage current (-9 nA at -20 V bias). (copyright 2014 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)

  4. FeLoBAL Outflow Variability Constraints from Multi-Year Observations

    The physical properties and dynamical behavior of Broad Absorption Line (BAL) outflows are crucial themes in understanding the connections between galactic centers and their hosts. FeLoBALs (identified with the presence of low-ionization Fe II BALs) are a peculiar class of quasar outflows that constitute approximately 1% of the BAL population. With their large column densities and apparent outflow kinetic luminosities, FeLoBALs appear to be exceptionally powerful and are strong candidates for feedback in galaxy evolution. We conducted variability studies of 12 FeLoBAL quasars with emission redshifts between 0.69 and 1.93, spanning both weekly and multi-year timescales in the quasar's rest frame. We detected absorption-line variability from low-ionization species (Fe II, Mg II) in four of our objects, with which we established a representative upper limit for the distance of the absorber from the supermassive black hole (SMBH) to be approximately 20 parsecs. Our goals are to understand the mechanisms producing...

    Studies of radio-loud (RL) broad absorption line (BAL) quasars indicate that popular orientation-based BAL models fail to account for all observations. Are these results extendable to radio-quiet (RQ) BAL quasars? Comparisons of RL and RQ BAL quasars show that many of their properties are quite similar. Here we extend these analyses to the rest-frame ultraviolet (UV) spectral properties, using a sample of 73 RL and 473 RQ BAL quasars selected from the Sloan Digital Sky Survey (SDSS). Each RQ quasar is individually matched to a RL quasar in both redshift (over the range $1.5 < z < 3.5$) and continuum luminosity. We compare several continuum, emission line, and absorption line properties, as well as physical properties derived from these measurements. Most properties in the samples are statistically identical, though we find slight differences in the velocity structure of the BALs that cause apparent differences in CIV emission line properties. Differences in the velocities may indicate an interaction bet...

    Coal workers' pneumoconiosis (CWP) is an occupational pulmonary disease that occurs by chronic inhalation of coal dust. CWP is divided into two stages depending on the extent of the disease, as simple pneumoconiosis (SP) and progressive massive fibrosis (PMF). In the present study, serum and bronchoalveolar lavage (BAL) cytokine (interleukin-1 beta (IL-1 beta), IL-6, tumor necrosis factor-alpha (TNF-alpha), transforming growth factor-beta (TGF-beta)) and antioxidant enzymes levels, their relation with the disease severity, and whether they can be considered as biological markers were investigated. Serum and BAL levels of IL-1 beta, IL-6, and TNF-alpha were higher in SP and PMF patient groups compared with that in active and retired miner groups. Serum and BAL IL-1 beta, IL-6, and TNF-alpha levels were also found to be higher in patients with PMF compared with the SP group. BAL superoxide dismutase (SOD), glutathione peroxidase, and catalase levels and serum SOD level were increased in both patient groups compared with the control group. In addition, mean serum and BAL TGF-beta levels were found to be increased in patients with SP compared with PMF group. Based on these results, BAL and serum cytokine and antioxidant enzymes levels were evaluated and discussed as potential biomarkers for different stages of CWP.

  9. HST images of FeLoBAL quasars: Testing quasar-galaxy evolution models

    Herbst, Hanna; Hamann, Fred; Villforth, Carolin; Caselli, Paola; Koekemoer, Anton M.; Veilleux, Sylvain

    2016-01-01

    We present preliminary results from an HST imaging study of FeLoBAL quasars, which have extremely low-ionization Broad Absorption Line (BAL) outflows and might be a young quasar population based on their red colors, large far-IR luminosities (suggesting high star formation rates), and powerful outflows. Some models of quasar - host galaxy evolution propose a triggering event, such as a merger, to fuel both a burst of star formation and the quasar/AGN activity. These models suggest young quasars are initially obscured inside the dusty starburst until a "blowout" phase, driven by the starburst or quasar outflows like FeLoBALs, ends the star formation and reveals the visibly luminous quasar. Despite the popularity of this evolution scheme, there is little observational evidence to support the role of mergers in triggering AGN or the youth of dust-reddened quasars (such as FeLoBALs) compared to normal blue quasars.Our Cycle 22 HST program is designed to test the youth of FeLoBAL quasars and the connection of FeLoBALs to mergers. We obtain WFC3/IR F160W images of 10 FeLoBAL quasars at redshift z~0.9 (covering ~8500A in the quasar rest frame). We will compare the host galaxy morphologies and merger signatures of FeLoBALs with normal blue quasars (which are older according to the evolution model) and non-AGN galaxies matched in redshift and stellar mass. If FeLoBAL quasars are indeed in a young evolutionary state, close in time to the initial merging event, they should have stronger merger features compared to blue quasars and non-AGN galaxies. Preliminary results suggest that this is not the case - FeLoBAL quasars appear to reside in faint, compact hosts with weak or absent merger signatures. We discuss the implications of these results for galaxy evolution models and other studies of dust-reddened quasar populations.

    Dr. Marcel Leclercq was a pioneer in the field of forensic entomology. He has provided his knowledge of insect biology to many forensic cases, and most of them have found the way to publication. Most of the articles he has written were focused on individual cases, and despite the abundance of entomoforensic investigations he conducted, no synthesis has been published. This article summarizes 36 yr of forensic entomological investigations in temperate Europe, mainly in Belgium. Dr. Leclercq's work includes 132 entomological cases involving 141 human corpses found in various death scenes. Under certain conditions, insect specimens found at death scene can provide information on when (postmortem interval estimation), where and how a person died. More or less 100 insect species associated with a dead body have been identified by Dr. Leclercq.

    Uplifted ultramafic rocks represent an important vector for the transfer of carbon and reducing power from the deep subsurface into the biosphere and potentially support microbial life through serpentinization. This process has a strong influence upon the production of hydrogen and methane, which can be subsequently consumed by microbial communities. The Santa Elena Ophiolite (SEO) on the northwestern Pacific coast of Costa Rica comprises ~250 km(2) of ultramafic rocks and mafic associations. The climatic conditions, consisting of strongly contrasting wet and dry seasons, make the SEO a unique hydrogeological setting, where water-rock reactions are enhanced by large storm events (up to 200 mm in a single storm). Previous work on hyperalkaline spring fluids collected within the SEO has identified the presence of microorganisms potentially involved in hydrogen, methane, and methanol oxidation (such as Hydrogenophaga, Methylobacterium, and Methylibium spp., respectively), as well as the presence of methanogenic Archaea (such as Methanobacterium). Similar organisms have also been documented at other serpentinizing sites, however their functions have not been confirmed. SEO's hyperalkaline springs have elevated methane concentrations, ranging from 145 to 900 μM, in comparison to the background concentrations (modeling approaches. These results were combined to elucidate the bioenergetically favorable methane production and/or oxidation reactions in this tropical serpentinizing environment. The hyperalkaline springs at SEO contain a greater proportion of Archaea and methanogens than has been detected in any terrestrial serpentinizing system. Archaea involved in methanogenesis and anaerobic methane oxidation accounted from 40 to 90% of total archaeal sequences. Genes involved in methanogenic metabolisms were detected from the metagenome of one of the alkaline springs. Methanogenic activities are likely to be facilitated by the movement of nutrients, including dissolved

    We conduct a spectroscopic search of quasars observed by the Sloan Digital Sky Survey (SDSS) with broad absorption line (BAL) troughs due to Mg II and troughs due to Fe II that simultaneously exhibit strong Balmer narrow emission lines (NELs). We find that in a redshift range of 0.4 less than or equal to z less than or equal to 0.9 approximately 23 of the 70 Mg II BALs and 4 of a subset of 15 Fe II BALs exhibit strong Balmer emission. We also find significant fractions of Mg II BALs (approximately 23%) and those Mg II BALs with Fe II troughs (approximately 27%) have strong continuum reddening, E(B - V) greater than or equal to 0.1. From measurements of the Balmer decrement in three objects, we find similarly significant reddening of the NEL region in three of the four objects; the NELs in the fourth object are not measurable. We also include one object in this study not taken from the SDSS sample that shows Fe II absorption and strong narrow emission, but due to measurement uncertainty and low continuum redde...

    2004-01-01

    The mechanical properties of B/Al composite were measured at room temperature in the as-fabricated condition and after thermal-mechanical cycling(TMC). The effects of TMC on microstructure and tensile fracture behavior of B/Al composite were studied using transmission electron microscope(TEM) and scanning electron microscope(SEM). The fibers/matrix interfaces are degraded during TMC, the extent of which is enhanced with in creasing the cycles, causing a measurable decrease of stage Ⅰ modulus of the B/Al composite. The TMC induces the dislocation generation in the aluminum matrix and the dislocation density increases with the cycles. The synergistic effect of the matrix strengthening and the interfacial degradation during TMC is found to play an important role in controlling the changes of tensile strengths and fracture behavior of the composite. The ultimate tensile strength of the composite increases with the cycles increasing. The interfaces in the B/Al composite change from the strongly bonded states toward the appropriately-bonded ones with increasing the cycles. TMC will provide an approach of im proving the strength of B/Al composites.

    The accreditation process is, on the one hand, a tool used to homogenize procedures, rendering comparable and standardized processes of care, and on the other, a methodology employed to develop a culture of quality improvement. Although not yet proven by evidence-based studies that health outcomes improve as a result of an accreditation to excellence, it is undeniable that better control of healthcare processes results in better quality and safety of diagnostic and therapeutic pathways. The Regina Elena National Cancer Institute underwent the accreditation process in accordance with the standards criteria set by the Organisation of European Cancer Institutes (OECI), and it has recently completed the process, acquiring its designation as a Comprehensive Cancer Center (CCC). This was an invaluable opportunity for the Regina Elena Institute to create a more cohesive environment, to widely establish a culture of quality, to implement an institutional information system, and to accelerate the process of patient involvement in strategic decisions. The steps of the process allowed us to evaluate the performance and the organization of the institute and put amendments in place designed to be adopted through 26 improvement actions. These actions regarded several aspects of the institute, including quality culture, information communication technology system, care, clinical trials unit, disease management team, nursing, and patient empowerment and involvement. Each area has a timeline. We chose to present the following 3 improvement actions: clinical trial center, computerized ambulatory medical record, and centrality of patient and humanization of clinical pathway.

    Full Text Available By analyzing the narrative of Marcel's journey by the "little train" from Balbec to Douville-Féterne the essay engages with the Proust criticism of Georges Poulet, Paul de Man, and Julia Kristeva to support Hayden White's claim that "it is legitimate to read Proust's narrative as an allegory of figuration itself." Like the Madeleine episode, this one serves as a point from which retrospection and prospection radiate. Central to the discussion is the description of Verdurins' dinner party guests as they stand ready to board the train on the platform at Graincourt: their vivacity, compared to a sort of extinction, suggests a chiasmus between life and death, past and present, experience and reading, and phenomenon and figuration that enriches and integrates Poulet's phenomenological glosses, de Man's rhetorical analysis, and the Kristevan approach to Proust's text. In close proximity to the Verdurins' guests, Marcel is struck chiefly by their remoteness, their pastness, their distance: the figural and phenomenal instability of space and time finally converge in Marcel himself as Proust effects a biblical joke.

  7. As cidades de Proust: um estudo sobre o estatuto dos nomes de cidades na literatura de Marcel Proust

    Directory of Open Access Journals (Sweden)

    Adson Cristiano Bozzi Ramatis Lima

    2012-11-01

    Full Text Available É bem conhecido que os nomes não são neutros, posto que indicam certos estados, objetos, fatos e situações, e aquele que faz uso de um nome pode estar se referindo a algo que, longe de deixá-lo“indiferente”, desperta-lhe uma viva emoção. Esta capacidade que as palavras possuem de remeter a conteúdos fortemente simbólicos retira-as do mundo dos signos para inscrevê-las em um domínio que poderíamos muito bem nomear de o seu “poder de evocação”. Já foi amplamente discutido qual é a importância do nome próprio na literatura de Marcel Proust, sobretudo na teoria anunciada no últimocapítulo do livro Du côté de chez Swann, e, neste sentido, é mister perceber que os nomes das cidades não apenas se referem a entidades geográficas, mas as moldam, as constroem, na medida em que criam uma expectativa. E pode ser uma cidade ainda desconhecida, ou uma cidade já conhecida evocada pela lembrança. O objetivo deste artigo, então, é demonstrar a importância do nome próprio – e, mais especificamente, nomes de cidades – na obra capital de Proust.

  8. Nem holismo nem individualismo metodológicos: Marcel Mauss e o paradigma da dádiva

    Caillé Alain

    1998-01-01

    Full Text Available O artigo se situa no contexto da crítica ao utilitarismo que vem sendo conduzida, desde o início dos anos 80, por um grupo de intelectuais reunidos em torno do MAUSS - Movimento Antiutilitarista nas Ciências Sociais, cujas idéias são divulgadas pela La Revue du MAUSS, publicada pela Editora La Découverte, em Paris. Alain Caillé procura resgatar a importância de Marcel Mauss no interior da escola sociológica francesa, ressaltando a contribuição deste autor clássico na sistematização inicial do paradigma do dom, que subsiste na modernidade, como o demonstram, em várias oportunidades, os colaboradores deste movimento antiutilitarista. Para Caillé, o paradigma do dom constitui o fundamento necessário de criação de uma teoria paradoxal e pluridimensional da ação, capaz de resolver a dicotomia clássica entre holismo e individualismo. No entanto, ressalta o diretor da Revue du MAUSS, na constituição do novo paradigma, as imbricações entre o dom e o simbolismo ainda permanecem imprecisas e algo misteriosas.

    2016-06-01

    Full Text Available Le roman de K. Schippers, De Bruid van Duchamp, publié en 2010 aux éditions Querido (Amsterdam, est l'expression de l’admiration nourrie depuis ses débuts par l'auteur pour Marcel Duchamp. Dans les années 1960, Schippers se distingue par l'introduction du ready made dans la poésie néerlandophone. Contrairement à la masse d'ouvrages consacrés à Duchamp, Schippers a conçu l'écriture de ce roman en fonction de son contenu : pour restituer l'esprit duchampien, Schippers ne procède pas à une énième analyse ou à l'élaboration de paradigmes d'étude, mais travaille sur le style. Le roman est un mélange des genres policier et biographique, ponctué d’éléments sur la réception de Duchamp aux Pays-Bas dans les années 1960. Comment mieux évoquer Duchamp, artiste du mystère et de la surprise qui voulait faire de sa vie une œuvre d'art ? Dans la traduction française du livre que nous élaborons actuellement, nous avons tenté de restituer cette correspondance de la forme à son contenu.

  12. BAL31-NGS approach for identification of telomeres de novo in large genomes.

    Science.gov (United States)

    Peška, Vratislav; Sitová, Zdeňka; Fajkus, Petr; Fajkus, Jiří

    2017-02-01

    This article describes a novel method to identify as yet undiscovered telomere sequences, which combines next generation sequencing (NGS) with BAL31 digestion of high molecular weight DNA. The method was applied to two groups of plants: i) dicots, genus Cestrum, and ii) monocots, Allium species (e.g. A. ursinum and A. cepa). Both groups consist of species with large genomes (tens of Gb) and a low number of chromosomes (2n=14-16), full of repeat elements. Both genera lack typical telomeric repeats and multiple studies have attempted to characterize alternative telomeric sequences. However, despite interesting hypotheses and suggestions of alternative candidate telomeres (retrotransposons, rDNA, satellite repeats) these studies have not resolved the question. In a novel approach based on the two most general features of eukaryotic telomeres, their repetitive character and sensitivity to BAL31 nuclease digestion, we have taken advantage of the capacity and current affordability of NGS in combination with the robustness of classical BAL31 nuclease digestion of chromosomal termini. While representative samples of most repeat elements were ensured by low-coverage (less than 5%) genomic shot-gun NGS, candidate telomeres were identified as under-represented sequences in BAL31-treated samples.

    Bronchoalveolar lavage (BAL) and {sup 18}F-fluorodeoxyglucose ({sup 18}F-FDG) PET can both demonstrate sarcoid activity. To assess whether metabolic activity imaged by {sup 18}F-FDG PET represents signs of disease activity as reflected by BAL, {sup 18}F-FDG PET patterns were compared with BAL cell profiles. In this retrospective analysis, 77 newly diagnosed pulmonary sarcoidosis patients underwent BAL and {sup 18}F-FDG PET. Based on {sup 18}F-FDG PET, patients were diagnosed with exclusively mediastinal/hilar activity (group A) and activity in the lung parenchyma (group B). Per group, BAL lymphocytes (%), CD4/CD8 ratio, CD103{sup +}CD4{sup +}/CD4{sup +} ratio and neutrophils (%) were compared with the extent of metabolic activity expressed as the maximum standardized uptake value (SUV{sub max}). Additionally, SUV{sub max} and BAL parameters per radiographic stage were analysed. Overall, the SUV{sub max} in the lung parenchyma correlated with neutrophils and SUV{sub max} of the mediastinum/hila correlated with the CD4/CD8 ratio. In both groups, a significant, negative correlation between the SUV{sub max} of the mediastinum/hila and the CD103{sup +}CD4{sup +}/CD4{sup +} ratio was found. In group B, the SUV{sub max} of the mediastinum/hila correlated with the CD4/CD8 ratio, while the SUV{sub max} in the lung parenchyma correlated with the CD103{sup +}CD4{sup +}/CD4{sup +} ratio and neutrophils. Significant differences were found in the SUV{sub max}, CD4/CD8 ratio, CD103{sup +}CD4{sup +}/CD4{sup +} ratio and neutrophils between the radiographic stages. The SUV{sub max} of the lung parenchyma was positively related to the radiographic stage, while the SUV{sub max} of the mediastinum/hila and CD4/CD8 ratio were inversely related. {sup 18}F-FDG PET correlates with the CD4/CD8 ratio and neutrophils, suggesting that {sup 18}F-FDG PET represents this specific cell profile in BAL. High SUV{sub max} values of the lung parenchyma may therefore correlate with more severe

    is a planetary process that has important consequences on geochemical cycles, supporting microbial activity through the formation of H2 and CH4 and having the potential to sequester atmospheric CO2. We present geochemical evidence of active serpentinization in the Santa Elena Ophiolite, Costa Rica which is sustained by peridotites with a degree of serpentinization less than 50% with no evidence of an internal heat source. Average spring water temperatures are 29.1°C. Two hyperalkaline spring systems were discovered, with a spring fluid pH up to 11.18. The fluids are characterized by low Mg (1.0-5.9 mg/L) and K (1.0-5.5 mg/L) and relative high Ca (29-167 mg/L), Na (16-27 mg/L), Cl (26-29 mg/L), hydroxide (41-63 mg/L), and carbonate (31-49 mg/L). Active CH4 (24.3% v/v) vents coupled with carbonate deposits (δ13CCO2 =-27 to -14‰; δ18OCO2 =-17 to - 6‰) also provide evidence for active serpentinization and carbonation. Isotope ratios of the alkaline fluids (δ18O = -7.9‰, δ2H = -51.4‰) and groundwater (δ18O = -7.6‰; δ2H = -48.0‰) suggests that, during base flow recession, springs are fed by groundwater circulation. Methanogenic Archaea, which comprises a relatively high percentage of the 16S rRNA gene tag sequences, suggests that biological methanogenesis may play a significant role in the system. Santa Elena's extreme varying weather results in a scenario that could be of significant importance for (a) improving the knowledge of conditions on a humid early Earth or Mars that had periodic changes in water supply, (b) revealing new insights on serpentinizing solute transport, and (c) modeling hydrogeochemical responses as a function of recharge.

    Resistance to microtubule targeting agents (MTA) represents a major drawback in successful cancer therapy with MTAs. Here we investigated the combined treatment modality of the novel MTA BAL101553 in combination with radiotherapy in paclitaxel and epothilone-resistant tumor models. Multiple regimens of BAL101553, or its active moiety BAL27862 for in vitro experiments, were probed in combination with radiotherapy in P-glycoprotein-overexpressing, human colon adenocarcinoma cells (SW480) and in tubulin-mutated human NSCLC cells (A549EpoB40) and tumors thereof. BAL27862 reduced the proliferative activity of SW480 and A549EpoB40 tumor cells with similar potency as in A549 wildtype cells. Combined treatment of BAL27862 with ionizing radiation in vitro resulted in an additive reduction of clonogenicity. Moreover, treatment of paclitaxel- and epothilone-resistant tumors with fractionated irradiation and different regimens of BAL101553 (a single i.v. bolus vs. oral daily) suppressed tumor growth and resulted in an extended additive tumor growth delay with strong reduction of tumor proliferation and mean tumor vessel density. BAL101553 is a promising alternative in taxane- and epothilone-refractory tumors as part of a combined treatment modality with ionizing radiation. Its potent antitumor effect is not only tumor cell-directed but also targets the tumor microenvironment. Copyright © 2017 Elsevier B.V. All rights reserved.

  1. XMM-Newton Observation of Fe K(alpha) Emission from a BAL QSO: Mrk 231

    Turner, T. J.; Kraemer, S. B.

    2003-01-01

    We present results from a 20 ksec XMM-Newton observation of Mrk 231. EPIC spectral data reveal strong line emission due to Fe K alpha, which has rarely been detected in this class, as BAL QSOs are very faint in the X-ray band. The line energy is consistent with an origin in neutral Fe. The width of the line is equivalent to a velocity dispersion approximately 18,000 kilometers per second and thus the line may be attributed to transmission and/or reflection from a distribution of emitting clouds. If, instead, the line originates in the accretion disk then the line strength and flat X-ray continuum support some contribution from a reflected component, although the data disfavor a model where the hard X-ray band is purely reflected X-rays. The line parameters are similar to those obtained for the Fe Ka line detected in another BAL QSO, H1413 + 117.

  2. 100-nm thick single-phase wurtzite BAlN films with boron contents over 10%

    Growing thicker BAlN films while maintaining single-phase wurtzite structure and boron content over 10% has been challenging. In this study, we report on the growth of 100 nm-thick single-phase wurtzite BAlN films with boron contents up to 14.4% by MOCVD. Flow-modulated epitaxy was employed to increase diffusion length of group-III atoms and reduce parasitic reactions between the metalorganics and NH3. A large growth efficiency of ∼2000 μm mol−1 was achieved as a result. Small B/III ratios up to 17% in conjunction with high temperatures up to 1010 °C were utilized to prevent formation of the cubic phase and maintain wurtzite structure.

    2016-04-01

    This paper describes the functionality and usage of BAL, a C/C++ library with a Python front-end for the brute-force analysis of continuous-time dynamical systems described by ordinary differential equations (ODEs). BAL provides an easy-to-use wrapper for the efficient numerical integration of ODEs and, by detecting intersections of the trajectory with appropriate Poincaré sections, allows to classify the asymptotic trajectory of a dynamical system for bifurcation analysis. Some examples of application are discussed, concerning two-dimensional bifurcation diagrams, Lyapunov exponents and finite-time Lyapunov exponents, basins of attraction, simulation of switching ODE systems, and integration with AUTO, a software package for continuation analysis.

    Full Text Available Since the publication of Marcel Proust’s A la recherche du temps perdu (1913-1927, multiple artists have taken up the challenge of visualizing his modernist magnum opus. In this article, I will discuss the interpretation of Dutch artist Kees van Dongen, who created 77 illustrations for a luxury edition published by Gallimard in 1947. By looking at the way Van Dongen visualized different forms of art, I will argue that Van Dongen’s interpretation is more artistically interesting than has been asserted before, as there are many intertextual and even intermedial references and practices to be found in Van Dongen’s aquarelles.

  7. A Physical Model of FeLoBALs: Implications for Quasar Feedback

    CERN Document Server

    Faucher-Giguere, C -A; Murray, N

    2011-01-01

    Photoionization modeling of the low-ionization broad absorption lines of certain quasars, known as FeLoBALs, has recently revealed the number density of the wind absorbers and their distance from the central supermassive black hole. From these, the feedback efficiency of the quasars can in principle be derived. The implied properties of the FeLoBALs are, however, surprising, with the thickness of the absorbers relative to their distance from the black hole, Delta R/R, as small as ~10^-5. Such absorbers are unlikely to survive the journey from the supermassive black hole to their inferred location. We show that the observed FeLoBAL properties are readily explained if they are formed in situ in radiative shocks produced when a quasar blast wave impacts a moderately dense interstellar clump along the line of sight. This physical picture differs significantly from the thin shell approximation often assumed, and implies outflow rates, kinetic luminosities and momentum fluxes that differ correspondingly, in some ca...

  8. Major Element Geochemistry of Peridotites from Santa Elena Ophiolite Complex, NW Costa Rica and Their Tectonic Implications

    Science.gov (United States)

    Wright, S.; Snow, J. E.; Gazel, E.; Sisson, V.

    2010-12-01

    The Santa Elena Ophiolite Complex (SEOC) is located on the west coast of Northern Costa Rica, near the Nicaraguan border. It consists primarily of preserved oceanic crustal rocks and underlying upper mantle thrust onto an accretionary complex. The petrogenesis and tectonic origin of this complex have widely been interpreted to be either a preserved mantle portion of the Caribbean Large Igneous Province (CLIP) as it drifted between North and South America from the Galapagos hotpot into the present day Caribbean Ocean around 80 Ma or as the mantle section to the nearby Nicoya complex. Previous structural work suggests that SEOC is a supra-subduction complex, not related to the CLIP or Nicoya. Our preliminary results agree. Mantle peridotites collected from the Santa Elena Ophiolite Complex consist primarily of spinel lherzolite (61 %) with minor amounts of harzburgite and dunite (22 % and 16 % respectively). Spinel Cr# [molar Cr / (Cr+Al)*100] is widely accepted to constrain mantle partial melting and lithospheric melt stagnation. Cr# of spinels within Santa Elena lherzolites fall between 12 and 35, suggesting an extent of 3 % to 13 % partial melting. Cr# of harzburgites range from 35 to 39, suggesting 13 % to 14 % partial melting. This range of partial melting suggests only modest depletion of this exposed portion of the ancient uppermost mantle. TiO2 concentrations of the lherzolite and harzburgite range from 0.004% to 0.128%, with the exception of one sample, SE10 - 17 (0.258%), and fall within the normal melting trend for mantle peridotites. The presence of dunite indicates that melt flow and associated melt - rock reaction with the surrounding peridotite took place within this portion of the mantle. A Cr# of 84.5 from one of these dunite samples indicate that significant melt rock reaction with refractory melts took place. Such results are rarely found in mid-ocean ridge abyssal peridotite settings, and are currently found primarily in forearc tectonic settings

  9. Is There any Relationship Between the Santa Elena Depression and Chicxulub Impact Crater, Northwestern Yucatan Peninsula, Mexico?

    Lefticariu, L.

    2005-05-01

    The Terminal Cretaceous Chicxulub Impact Crater had a strong control on the depositional and diagenetic history of the northern Yucatan Platform during most of the Cenozoic Era. The Chicxulub Sedimentary Basin (henceforth Basin), which approximately coincides with the impact crater, is circumscribed by a concentration of karstic sinkholes known as the Ring of Cenotes. Santa Elena Depression (henceforth Depression) is the name proposed for the bowl-shaped buried feature, first contoured by geophysical studies, immediately south of the Basin, in the area where the Ticul 1 and UNAM 5 wells were drilled. Lithologic, petrographic, and biostratigraphic data on PEMEX, UNAM, and ICDP cores show that: 1) Cenozoic deposits are much thicker inside the Basin than inside the Depression, 2) in general, the Cenozoic formations from inside the Depression are the thickest among those outside the Basin, 3) variably dolomitized pelagic or outer-platform wackestone or mudstone occur both inside the Basin and Depression, 4) the age of the deeper-water sedimentary carbonate rocks is Paleocene-Eocene inside the Basin and Paleocene?-Early Eocene inside the Depression, 5) the oldest formations that crop out are of Middle Eocene age at the edge of the Basin and Early-Middle Eocene age inside the Depression, 6) saline lake deposits, that consist chiefly of anhydrite, gypsum, and fine carbonate, and also contain quartz, chert, clay, zeolite, potassium feldspar, pyrite, and fragments of wood, are present in the Cenozoic section of the UNAM 5 core between 282 and 198 m below the present land surface, 7) the dolomite, subaerial exposure features (subaerial crusts, vugs, karst, dedolomite), and vug-filling cement from the Eocene formations are more abundant inside the Depression than inside the Basin. The depositional environments that are proposed for explaining the Cenozoic facies succession within the Santa Elena Depression are: 1) deeper marine water (Paleocene?-Early Eocene), 2) relatively

    2015-12-01

    We present in situ LA-ICPMS data on platinum group element (PGE) and chalcophile element (namely Cu, Ag, Te, Au, Pb) systematics in sulfides from partially serpentinized peridotites of the St. Elena ophiolite, Costa Rica. PGE are strong indicators of primary mantle processes, though their behavior during low temperature alteration processes such as serpentinization is not well understood. St. Elena sulfides are dominantly pentlandites that coexist with Fe-Ni alloys and native Cu. This indicates extremely low fO2 and fS2 conditions likely established during the early stages of serpentinization. We observe extremely variable PGE-Re concentrations in the sulfides, (e.g. [Os] = 2 - 100,000 times primitive mantle, PM). Low [Os] sulfides have high Pd/Os, which in turn correlates positively with Cu concentrations, suggesting Pd enrichment through Cu-rich fluids (e.g. Schwarzenbach et al., 2014, CMP) as opposed to melt-rock reaction. Sulfide PM-normalized PGE-Re patterns are dominated by strong Pt depletions (e.g., Pt/Pd = 0.80-0.0009). Occasional Pt enrichments over Pd and Ru (or Rh) in a PM-normalized pattern (~5% of the sulfide population) often correlate with Te and/or Au enrichments. Pt enrichment was also observed in a composite pentlandite-awaruite, suggesting possible exsolution of Pt from sulfides under extremely low fS2 conditions. Pb concentrations do not correlate with other chalcophiles or PGE. Pb ranges from 0.01-31.64 ppm with the majority of sulfides <5 ppm, and an average concentration of 2.77 ppm (n=64). Assuming that this Pb concentration is representative of mantle sulfides, this implies that Pb is not dominantly held in sulfides in the upper mantle. Combination of in situ and bulk rock PGE analyses will be used to distinguish the effects of primary magmatic signatures (e.g., melt depletion, melt-rock interaction) and secondary processes such as serpentinization on the PGE-Re and chalcophile element systematics of these sulfides.

    We present the discovery of a z = 0.65 low-ionization broad absorption line (LoBAL) quasar in a post-starburst galaxy in data from the Dark Energy Survey (DES) and spectroscopy from the Australian Dark Energy Survey (OzDES). LoBAL quasars are a minority of all BALs, and rarer still is that this object also exhibits broad Fe II (an FeLoBAL) and Balmer absorption. This is the first BAL quasar that has signatures of recently truncated star formation, which we estimate ended about 40 Myr ago. The characteristic signatures of an FeLoBAL require high column densities, which could be explained by the emergence of a young quasar from an early, dust-enshrouded phase, or by clouds compressed by a blast wave. The age of the starburst component is comparable to estimates of the lifetime of quasars, so if we assume the quasar activity is related to the truncation of the star formation, this object is better explained by the blast wave scenario.

    Full Text Available En centrant l'étude sur deux courriers envoyés à Antoine Meillet par Marcel Cohen et Gaston Esnault (tirés du fonds d'archives de l'IMEC, cette étude se propose de reconstituer la façon dont la prise en compte de l'argot, d'abord dominée, au cours du XIXe siècle, par un paradigme philologique et littéraire qui faisait la part belle à l'écrit, en particulier les textes de Villon et Rabelais, s'est trouvée radicalement transformée par l'expérience d'un contact direct entre quelques linguistes mobilisés lors de la Première Guerre Mondiale et les locuteurs d'un "argot des tranchées". Comme le montre l'analyse des documents et des comptes rendus parus dans le "Bulletin de la Société de Linguistique de Paris" entre 1916 et 1920, l'existence d'un "argot de guerre" a été soutenue par des savants qui n'avaient pas été amenés à porter les armes et qui ont mené leurs travaux à distance du front sur des corpus écrits, probablement fabriqués de toutes pièces par les services de propagande ou composés par des professionnels d'une littérature "montmartroise". La critique de M. Cohen sur le procédé et sur les conclusions qui avaient été tirées de telles études a été déterminante, un quart de siècle plus tard, dans la façon dont il a élaboré le programme d'une sociologie du langage, distincte de ses travaux en anthropologie, en écartant les erreurs de méthode qu'il avait dénoncées avec véhémence.

    The CERN Extra Low ENergy Antiproton (ELENA) Ring is a new synchrotron that will be commissioned in 2016 to further decelerate the antiprotons transferred from the CERN’s Antiproton Decelerator (AD). The requirements for the acquisition and treatment of signals for longitudinal diagnostics are very demanding, owing to the revolution frequency swing as well as to the digital signal processing required. The requirements for the Low-Level Radio-Frequency (LLRF) system are very demanding as well, especially in terms of revolution frequency swing, dynamic range and low noise required by the cavity voltage control and digital signal processing to be performed. Both sets of requirements will be satisfied by using a leading-edge hardware family, developed to cover the LLRF needs of all synchrotrons in the Meyrin site; it will be first deployed in 2014 in the CERN’s PSB and in the medical machine MedAustron. This paper gives an overview of the main building blocks of the hardware family and of th...

    Context. X-ray studies of AGN with powerful nuclear winds are important to constrain the physics of the inner accretion/ejection flow around SMBH, and to understand the impact of such winds on the AGN environment. Aims. Our main scientific goal is to constrain the properties of a variable outflowing absorber that is thought to be launched near the SMBH of the mini-BAL QSO PG 1126-041 using a multi-epoch observational campaign performed with XMM-Newton. Methods. We performed temporally resolved X-ray spectroscopy and simultaneous UV and X-ray photometry on the most complete set of observations and on the deepest X-ray exposure of a mini-BAL QSO to date. Results. We found complex X-ray spectral variability on time scales of both months and hours, best reproduced by means of variable massive ionized absorbers along the line of sight. As a consequence, the observed optical-to-X-ray spectral index is found to be variable with time. In the highest signal-to-noise observation we detected highly ionized X-ray absorbing material outflowing much faster (u(sub X) approx. 16 500 km/s) than the UV absorbing one (u(sub uv) approx. 5,000 km/s). This highly ionized absorber is found to be variable on very short (a few kiloseconds) time scales. Conclusions. Our findings are qualitatively consistent with line driven accretion disk winds scenarios. Our observations have opened the time-resolved X-ray spectral analysis field for mini-BAL QSOs; only with future deep studies will we be able to map the dynamics of the inner flow and understand the physics of AGN winds and their impact on the environment.

    We present the first in a series of papers in The role of Environment in shaping Low-mass Early-type Nearby galaxies (hELENa) project. In this paper, we combine our sample of 20 low-mass early types (dEs) with 258 massive early types (ETGs) from the ATLAS3D survey - all observed with the SAURON integral field unit - to investigate early-type galaxies' stellar population scaling relations and the dependence of the population properties on local environment, extended to the low-σ regime of dEs. The ages in our sample show more scatter at lower σ values, indicative of less massive galaxies being affected by the environment to a higher degree. The shape of the age-σ relations for cluster versus non-cluster galaxies suggests that cluster environment speeds up the placing of galaxies on the red sequence. While the scaling relations are tighter for cluster than for the field/group objects, we find no evidence for a difference in average population characteristics of the two samples. We investigate the properties of our sample in the Virgo cluster as a function of number density (rather than simple clustrocentric distance) and find that dE ages correlate with the local density such that galaxies in regions of lower density are younger, likely because they are later arrivals to the cluster or have experienced less pre-processing in groups, and consequently used up their gas reservoir more recently. Overall, dE properties correlate more strongly with density than those of massive ETGs, which was expected as less massive galaxies are more susceptible to external influences.

    Full Text Available La hemorragia postparto es un importante contribuyente a la morbilidad materna y sigue siendo la principal causa de mortalidad materna a nivel mundial; en la mayoría de los casos aparece en forma espontanea inmediata a la ocurrencia del parto, y el porcentaje mayor se refiere a la hipotonía uterina, que es rebelde a la aplicación de medidas convencionales como el masaje uterino, oxitócicos, prostaglandinas etc.Las pautas para el manejo de la hemorragia postparto implican medidas graduales desde enfoques farmacológicos hasta los quirúrgicos. El método de taponamiento uterino utilizando “balones hemostáticos” se ha añadido recientemente al arsenal de tratamiento de la hemorragia postparto. Hay varios balones disponibles, incluyendo el Balón de Bakri, Foley,Sengstaken-Blakemore, Rusch, entre otros.

    Ceftobiprole (BAL9141) is an investigational cephalosporin active against methicillin- and vancomycin-resistant staphylococci administered as a water-soluble prodrug, ceftobiprole medocaril (BAL5788). Using an immunocompetent murine pneumonia model of Haemophilus influenzae, Enterobacter cloacae, or extended-spectrum beta-lactamase (ESBL) nonproducing or producing Klebsiella pneumoniae pneumonia, we compared results of treatment with ceftobiprole medocaril (71 mg/kg, sc, qid), ceftriaxone (50 mg/kg, im, bid), or cefepime (50 mg/kg, ip, q.i.d.). Results were expressed as median and 25th to 75th percentile log10 colony forming units per gram of lung tissue. Ceftobiprole, ceftriaxone, and cefepime were each more active than was no treatment and were equally active for treatment of experimental H. influenzae, E. cloacae, or ESBL-nonproducing K. pneumoniae pneumonia. For ESBL-producing K. pneumoniae, no differences were detected between no treatment and treatment with ceftobiprole, ceftriaxone, or cefepime. Ceftobiprole is active against H. influenzae, E. cloacae, and ESBL-nonproducing K. pneumoniae in an immunocompetent experimental murine pneumonia model.

    Full Text Available Le roman de K. Schippers, De Bruid van Marcel Duchamp, publié en 2010 aux éditions Querido (Amsterdam, est l'expression de l’admiration nourrie depuis ses débuts par l'auteur pour Marcel Duchamp. Dans les années 1960, Schippers se distingue par l'introduction du ready made dans la poésie néerlandophone. Contrairement à la quantité d'ouvrages consacrés à Duchamp, Schippers a conçu  l'écriture de ce roman en fonction de son contenu : pour restituer l'esprit duchampien, Schippers ne procède pas à une énième analyse ou à l'élaboration de nouveaux paradigmes d'étude, mais travaille sur le style. Son roman est un mélange des genres policier et biographique, ponctué d’éléments sur la réception de Duchamp aux Pays-Bas dans les années 1960. Schippers part de la question « Qui est la mariée qui figure si souvent dans l'œuvre de Duchamp ? ». Tel un enquêteur, il tente de résoudre cette question en se rendant sur les crime scenes, c'est-à-dire sur tous les lieux où Duchamp a vécu et travaillé. Il y mène des entretiens avec les amis de Duchamp ou leur famille afin de mieux comprendre qui était cet artiste qui aimait se draper de mystère et qui voulait faire de sa vie une œuvre d'art.

  12. Sulfur and carbon geochemistry of the Santa Elena peridotites: Comparing oceanic and continental processes during peridotite alteration

    2016-05-01

    Ultramafic rocks exposed on the continent serve as a window into oceanic and continental processes of water-peridotite interaction, so called serpentinization. In both environments there are active carbon and sulfur cycles that contain abiogenic and biogenic processes, which are eventually imprinted in the geochemical signatures of the basement rocks and the calcite and magnesite deposits associated with fluids that issue from these systems. Here, we present the carbon and sulfur geochemistry of ultramafic rocks and carbonate deposits from the Santa Elena ophiolite in Costa Rica. The aim of this study is to leverage the geochemistry of the ultramafic sequence and associated deposits to distinguish between processes that were dominant during ocean floor alteration and those dominant during low-temperature, continental water-peridotite interaction. The peridotites are variably serpentinized with total sulfur concentrations up to 877 ppm that is typically dominated by sulfide over sulfate. With the exception of one sample the ultramafic rocks are characterized by positive δ34Ssulfide (up to + 23.1‰) and δ34Ssulfate values (up to + 35.0‰). Carbon contents in the peridotites are low and are isotopically distinct from typical oceanic serpentinites. In particular, δ13C of the inorganic carbon suggests that the carbon is not derived from seawater, but rather the product of the interaction of meteoric water with the ultramafic rocks. In contrast, the sulfur isotope data from sulfide minerals in the peridotites preserve evidence for interaction with a hydrothermal fluid. Specifically, they indicate closed system abiogenic sulfate reduction suggesting that oceanic serpentinization occurred with limited input of seawater. Overall, the geochemical signatures preserve evidence for both oceanic and continental water-rock interaction with the majority of carbon (and possibly sulfate) being incorporated during continental water-rock interaction. Furthermore, there is

    Full Text Available The article examines the administrative thinking of Aníbal Bascuñán Valdés, derived from the analysis of his book Elementos de Ciencia de la Administración Pública (1963. It highlights the value of Bascuñán to the intellectual history of the discipline, for being the first Hispanic American thinker who without hesitation supported the autonomous status of public administration and for conceiving it as scientific knowledge under an ontic approach, where his being is endowed with an identity and able to develop principles. It is concluded that the work of Bascuñán is one of the most developed within the discipline during the 1960s,above all because it considers public administration as an autonomous science and social science.

    We study the dramatic decrease in iron absorption strength in the iron low-ionization broad absorption line quasar SDSS J084133.15+200525.8. We report on the continued weakening of absorption in the prototype of this class of variable broad absorption line quasar, FBQS J140806.2+305448. We also report a third example of this class, SDSS J123103.70+392903.6; unlike the other two examples, it has undergone an increase in observed continuum brightness (at 3000~\\AA\\ rest-frame) as well as a decrease in iron absorption strength. These changes could be caused by absorber transverse motion or by ionization variability. We note that the \\mgii\\ and UV \\feii\\ lines in several FeLoBAL quasars are blueshifted by thousands of \\kms\\ relative to the \\Hb\\ emission line peak. We suggest that such emission arises in the outflowing winds normally seen only in absorption.

    Ricinulei is an order of Arachnida composed of rare and little known species. The species of Ricinulei possess a rich variety of fine integumentary structures that have been poorly investigated in a few species. Besides, several structures are still undescribed and their function not yet addressed. In this paper we provide a detailed study of the integumentary morphology of Cryptocellus bordoni Dumitresco and Jurvara-Bals, 1976 using Light and Scanning Electron Microscopy. We describe and present photos of the new and already known fine integumentary structures. We compare the new structures to those previously described for other Ricinulei species and discuss their taxonomic implications and the placement of C. bordoni in the genus Cryptocellus.

    2003-01-01

    New solid-phase strategies have been developed for the synthesis of lidocaine (1) and procainamide (2) analogues, using backbone amide linker (BAL) anchoring. Both sets were prepared starting from a common resin-bound intermediate, followed by four general steps: (i) attachment of a primary aliphatic or aromatic amine to the solid support via reductive amination (as monitored by a novel test involving reaction of 2,4-dinitrophenylhydrazine with residual aldehyde groups); (ii) acylation of the resultant secondary amine; (iii) displacement of halide with an amine; and (iv) trifluoroacetic acid-mediated release from the support. A manual parallel strategy was followed to provide 60 novel compounds, of which two dozen have not been previously described. In most cases, initial crude purities were >80%, and overall isolated yields were in the 40-88% range.

    Samples of CaBAl glass with composition of (25-x)CaO-50B2O3-15Al2O3-10CaF2-xSm2O3, with Sm2O3 concentration varying from 0.5 to 7 wt%, were prepared by using melt-quenching method in air atmosphere. The samples were prepared with different concentrations of Sm2O3, aiming to understand how the dopant changes the optical and spectroscopic properties of the glass. The doped CaBAl glasses were studied by means of volumetric density measurements, refractive index, optical absorption, luminescence at room temperature, luminescence as function of the temperature and radiative lifetime. All results were discussed in function of Sm2O3 concentration. The measured volumetric density and polarizability showed an increase with Sm2O3 doping. The refractive index showed a small increase due to RE doping, although within the errors. The absorption bands were attributed to Sm3+ transitions from the ground state 6H5/2 to the various excited states. The luminescence spectra present emission bands assigned to the appropriate electronic f-f transitions of Sm3+ ions; there are four emission bands at 565, 602, 649 and 710 nm. The luminescence quenching was observed up to 2 wt% of Sm2O3. The O/R ratio as function of the Sm2O3 concentration showed changes in the symmetry site with addition of Sm2O3. The CIE 1931 diagram presented a reddish-orange shift color with Sm2O3 doping. The luminescence intensity presents a decrease with temperature increase for all studied samples. The experimental lifetime decreases with the increase of Sm2O3, mainly due to ion-ion interaction.

    Club cell protein (CC16) is a pneumoprotein secreted by epithelial club cells. CC16 possesses anti-inflammatory properties and is a potential biomarker for airway epithelial damage. We studied the effect of inhaled allergen on pulmonary and systemic CC16 levels. Thirty-four subjects with allergic asthma underwent an inhaled allergen challenge. Bronchoscopy with bronchoalveolar lavage (BAL) and brushings was performed before and 24 h after the challenge. CC16 was quantified in BAL and CC16 positive cells and CC16 mRNA in bronchial brushings. CC16 was measured in plasma and urine before and repeatedly after the challenge. Thirty subjects performed a mannitol inhalation challenge prior to the allergen challenge. Compared to baseline, CC16 in plasma was significantly increased in all subjects 0-1 h after the allergen challenge, while CC16 in BAL was only increased in subjects without a late allergic response. Levels of CC16 in plasma and in the alveolar fraction of BAL correlated significantly after the challenge. There was no increase in urinary levels of CC16 post-challenge. Mannitol responsiveness was greater in subjects with lower baseline levels of CC16 in plasma. The increase in plasma CC16 following inhaled allergen supports the notion of CC16 as a biomarker of epithelial dysfunction.

A partir del proceso de colonización del Nuevo Mundo, el lucro de la guerra y la ambición por explotar la exuberante riqueza del territorio amerindio hicieron que el hombre blanco caníbal (una figura común en los imaginarios no-occidentales desatara esa máquina de guerra que devora personas y recursos para alimentar al Estado colonial.

Después de cinco siglos de coalición entre el poder político y la violencia, pareciera que la máquina de guerra caníbal no se ha saciado y reclama cada vez más sangre en nombre de la libertad y el progreso.

  17. SimBAL: A Spectral Synthesis Approach to Analyzing Broad Absorption Line Quasar Spectra

    Science.gov (United States)

    Terndrup, Donald M.; Leighly, Karen; Gallagher, Sarah; Richards, Gordon T.

    2017-01-01

    Broad Absorption Line quasars (BALQSOs) show blueshifted absorption lines in their rest-UV spectra, indicating powerful winds emerging from the central engine. These winds are essential part of quasars: they can carry away angular momentum and thus facilitate accretion through a disk, they can distribute chemically-enriched gas through the intergalactic medium, and they may inject kinetic energy to the host galaxy, influencing its evolution. The traditional method of analyzing BALQSO spectra involves measuring myriad absorption lines, computing the inferred ionic column densities in each feature, and comparing with the output of photonionization models. This method is inefficient and does not handle line blending well. We introduce SimBAL, a spectral synthesis fitting method for BALQSOs, which compares synthetic spectra created from photoionization model results with continuum-normalized observed spectra using Bayesian model calibration. We find that we can obtain an excellent fit to the UV to near-IR spectrum of the low-redshift BALQSO SDSS J0850+4451, including lines from diverse ionization states such as PV, CIII*, SIII, Lyalpha, NV, SiIV, CIV, MgII, and HeI*.

    A novel method for determination of psoralen photo-cross-linking sites in double-stranded DNA is described, which is based on a pronounced inhibition of Bal31 exonuclease activity by psoralen-DNA interstrand cross-links. The results using a 51 base pair fragment of plasmid pUC19 and a 346 base pair...... fragment of pBR322 show that 5'-TA sequences are preferred cross-linking sites compared to 3'-TA sequences. They also indicate that sequences flanking the 5'-TA site influence the cross-linking efficiency at the site. The DNA photo-cross-linking by 4,5',8-trimethylpsoralen and 8-methoxypsoralen...... was analyzed, and these two psoralens showed identical site specificity. The 5'-TA preference is rationalized on the basis of the local DNA structure in terms of the pi-pi electronic interaction between the thymines and the intercalated psoralens, as well as on the base tilt angles of the DNA....

    We present high-resolution observations, using both the European VLBI Network (EVN) at 1.7-GHz, and the Very Long Baseline Array (VLBA) at 5 and 8.4-GHz to image radio structures of 14 compact sources classified as broad absorption line (BAL) quasars based on the absorption index (AI). All source but one were resolved, with the majority showing core-jet morphology typical for radio-loud quasars. We discuss in details the most interesting cases. The high radio luminosities and small linear sizes of the observed objects indicate they are strong young AGNs. Nevertheless, the distribution of the radio-loudness parameter, log(Ri), of a larger sample of AI quasars shows that the objects observed by us constitute the most luminous, small subgroup of AI population. Additionally we report that for the radio-loudness parameter, the distribution of AI quasars and those selected by using the traditional balnicity index (BI), BI quasars differ significantly. Strong absorption is connected with the lower log(Ri), and thus ...

    Eu2O3 doped CaBAL glasses (x Eu2O3) - (25-x) CaO - (50) B2O3 - (15) Al2O3 - (10) CaF2 (x = 0, 5, 1, 2, 3, 4, 5, 10 wt%) were prepared by using conventional melt-quenching and studied by means of density measurements, refractive index, optical absorption, luminescence and radiative lifetime. The results are discussed in terms of Eu2O3 content. The incorporation of Eu2O3 leads to an increase in the electronic polarizability and the refractive index. A linear increase with Eu2O3 content was observed in the optical absorption coefficient at 394 nm. The luminescence spectra present typical Eu3+ emission and do not present quenching up to 10 wt%. The luminescence ratio R/O I(5D0 → 7F2)/I(5D0 → 7F1) presents an increase with Eu2O3 doping; it indicates a reduction in local symmetry around the Eu3+ ions. The CIE 1931 diagram presents a red shift and an increase of color purity with Eu2O3 addition. The luminescence as a function of temperature shows an increase of 25% in the luminescence intensity for the Eu0.5 sample, at 592 nm. The radiative lifetime at 614 nm shows an exponential decay due to the reduction of the interionic distance Eu3+ - Eu3+ and the increase of the ion-ion interaction.

    Ceftobiprole medocaril [BAL 5788, RO 65-5788, JNJ 30982081] is a prodrug in phase III clinical development with Basilea Pharmaceutica and Cilag AG (Johnson & Johnson) for the potential treatment of serious bacterial infections, including methicillin-resistant Staphylococcus aureus (MRSA). Ceftobiprole medocaril is the water-soluble prodrug of the pyrrolidinone cephalosporin, ceftobiprole [BAL 9141, RO 63-9141]. Because of the low water solubility of ceftobiprole, its clinical application was limited and Basilea began its investigations into ceftobiprole medocaril for further development. Ceftobiprole medocaril is being developed for IV administration and is currently undergoing phase III trials for complicated skin and skin structure infections (including MRSA) and hospital-acquired (nosocomial) pneumonia. Ceftobiprole medocaril has a broad spectrum of activity against Gram-positive bacteria (including methicillin-resistant staphylococci, penicillin-resistant pneumococci and Enterococcus faecalis) and Gram-negative bacteria. Ceftobiprole medocaril inhibits all transpeptidases, including the penicillin-binding protein (PBP) 2a, by a unique combination of features. PBP 2a is the primary enzyme responsible for beta-lactam drug resistance in MRSA; PBP 2a also acts as a key defense mechanism by interacting with the bacterial cell wall to form a chemical barricade that is impervious to antibiotics. Ceftobiprole medocaril has been designed specifically to bind to this penicillin-resistant target. Ceftobiprole medocaril is bactericidal and has not shown resistance development in vitro or in stringent animal models. Studies conducted by Basilea have demonstrated that ceftobiprole medocaril is readily converted to ceftobiprole, and shows markedly improved water solubility. In February 2005, Basilea Pharmaceutica AG entered into an exclusive worldwide agreement with Cilag AG International (Johnson & Johnson) to develop, manufacture and market ceftobiprole medocaril.

Ainsi nous arrêtons-nous sur le triple enjeu de « l’invention » du baroque occitan : I– Conférer une dignité littéraire à un ensemble d’écrits jusque là relégués au statut de « littérature patoise » II– Constituer un corpus unifié et cohérent pour une longue période s’étendant de la deuxième moitié du xvie siècle jusqu’à la Révolution française. III– Définir la spécificité et l’identité culturelle, stylistique et idéologique, et donc l’autonomie du corpus occitan vis à vis de la littérature française et des autres littératures européennes (en particulier italienne et espagnole du début de l’époque moderne. Nous insistons sur l’unité de fond des démarches de Castan et de Lafont à propos du baroque mais aussi sur les divergences d’analyse et d’enjeux intellectuels et idéologiques de leurs entreprises respectives.Our purpose here aims at describing the context of the first appearance of the syntagm “Occitan baroque” and to produce an analysis of the operations permitted by it, through the examination of intellectual endeavors related to the baroque of two of its main proponents Félix Castan-Marcel and Robert Lafont, major and antagonist figures of occitanism in the immediate post war.

La ciudad fue creada para que hombres y mujeres construyeran sus proyectos de vida en medio del Desierto de Atacama, ofreciéndoles todas las garantías y la infraestructura para que ello fuese así en los marcos de una política de pleno empleo, de modo de contener a la población en un medio inhóspito, cumplir los objetivos productivos y fortalecer una identidad coherente y cohesionada, lo que a partir de nuevas decisiones estratégicas es substituido por un modelo de flexibilidad laboral, lo que anula su definición primigenia y el interés colectivo para comenzar a dar paso a un campamento minero.In this paper we look into the relationship between the nitrate town of Maria Elena (in Region II - designed on Utopian principals as a private project - and the changing labor relations between the SQM Company and the workers as a result of the predominance of a new accumulation model guided by competitiveness, quality production and globalization. The town was created so that men and women could establish their livelihoods in the Atacama Desert, with guarantees and infrastructure based on a full employment policy. This was in order to anchor the population in this inhospitable environment, to meet production objectives and to strengthen a coherent and cohesive identity. New strategic decisions led to this model being replaced by one based on labour flexibilization, deleting its original intention and collective interest to give way to a mining camp.

    Full Text Available One of the entomopatogenous fungus types commonly observed and showed potency as myco-insectiside is Beauveria bassiana(Bals. Vuill.In order to support effectiveness and patogenous activity of B. bassiana, it is necessary to add a carrying agent that protects its spores from ultra violet ray. This study aims to investigate the effect of storage temperature on viability of B. Bassianaspores on the carrier material. The observation was carried out in the Laboratory of Plant Diseases, Indonesian Coffee and Cocoa Research Institute. The research was arranged in completely randomized design by three factors. The first factor was carrier (C, that consists of C1 = rice flour, C2 = maize flour and C3 = tapioca flour. The second factor was dosage (D, that consists of D1 = 1 g B. bassiana+ 1 g carrier; D2 = 1 g B. bassiana+ 5 g carrier and D3 = 1 g B. bassiana+ 10 g carrier. The third factor was temperature of the storage (T,that consists of T1 = 5oC; T2 = 23oC and T3 = 29oC. Viability of B. Bassiana spores was examined by observing development of 100 blastopores randomly and determined under light microscope with 400 times magnification. Observation was conducted in two replicates after the spores of B. bassiana were kept in the storage for 2, 4, 8 and 16 weeks. The result showed that by adding 1 g tapioca flour and temperature of storage of 5oC was potentiall in keeping viability of B. bassianaspores at least for 2 months. It was due to that tapioca flour gave better effect than rice and maize flours in keeping the storage and appropriate low temperature. Viability of B. bassianaspores decreased with increasing carrier dosage, temperature and duration of the storage. Whereas, storage at 5oC was found to be a better condition in keeping viability of dry pure B. bassianaspores longer than conditions of 23o and 29oC. Key word:Beauveria bassiana, temperature, viability,carrier.

    Full Text Available Background Bacillus cereus is a Gram-positive spore-forming bacterium, which causes food poisoning. Spores enable the persistence of B. cereus in the environment, and B. cereus strains can tolerate adverse environmental conditions, such as temperature and insufficient nutrients. B. cereus causes food poisoning via the production of two enterotoxins. Most isolates produce toxins leading to diarrhea (enterotoxins and vomiting (emetic forms. Diarrhea is caused by the production of three different heat-labile enterotoxins: HBL, NHE, and cytotoxin K. A heat-stable toxin, cereulide, is responsible for emesis. Objectives This study aimed to detect enterotoxigenic B. cereus isolates in cheese samples using the polymerase chain reaction (PCR. Materials and Methods Two-hundred pasteurized (n = 100 and nonpasteurized (n = 100 cheese samples were collected. The initial isolation was performed on PEMBA specific medium. Antibiotic susceptibility testing was performed using several antibiotic disks, according to the guidelines of the Clinical Laboratory and Standards Institute. Specific primers amplifying the hblA enterotoxin-encoding gene and bal hemolysin-encoding gene were used for the molecular detection of the toxins. Results Ten samples were positive for the presence of B. cereus, with both Gram staining and biochemical reactions. All the isolates were resistant to penicillin and ampicillin but susceptible to vancomycin, erythromycin, and ciprofloxacin. Six and three isolates were resistant to tetracycline and trimethoprim-sulfamethoxazole, respectively. The hblA and bal genes were amplified in all the B. cereus isolates. Conclusions The prevalence of B. cereus among the cheese samples was low. All the isolates were positive for genes encoding the hblA enterotoxin and bal toxin.

    Full Text Available Background: The intragastric balloon is widely used for weight reduction in obese patients, but results are variable. We describe our results enhancing the importance of a Multidisciplinary Team (MT taking part in the treatment. Methods: A retrospective review was done concerning a total of 119 balloons , placed in 116 patients, under endoscopic control and conscious sedation, from May 2001 until August 2006. 49 patients were prepared and recommended to be followed by a MT in a physical unit, at least every 15 days during 6 months. 67 were indicated and followed by other colleagues, without MT. Removal was performed 6 months later. Results: Concerning our 49 patients, mean age was 38, 1 years, 31 female and 18 males, with BMI ranged between 32 and 63, average of 42. The average decrease of weight excess was 31, 85% (-4, 45-80, 4%, and the BMI diminished 5,3 points (from 13,6 to gain of 0,9. The treatment failed in 34,6 % of our patients -including 4 patients lost of follow-up (8, 16%-, compared with 53, 8% of patients without structured MT for selection and follow-up. Physical exercise enhanced markedly the results with 45, 8% of excess of weight loss in women and 39, 7% in males, compared with 14, 6 and 15, 6% in patients who didn't follow the program. The weight loss was mostly fat mass, 89,9% in men and 75,6% in women.- The results maintenance was obtained in 40% of patients one year later. There were no major complications; one balloon had to be removed at 3 weeks because of intolerance, another at 5 months because of gastroesophageal reflux. Conclusions: BIB is an effective help to achieve a short term weight loss in obese patients; nevertheless, good and long lasting results will depend on the modification of life style obtained by a multidisciplinary approach.Antecedentes: el balón intragástrico se usa ampliamente para la reducción de peso de pacientes obesos pero sus resultados son variables.

    [Objective] This study was to investigate the relationship between biological characteristics of Beauveria bassiana (Bals.) Vuill and pathogenicity to Bombyx rnori L, with the aim to provide scientific basis for the control of white muscardine in Bombyx mori L. [Method] The strains isolated and purified from the 6 Beauveria bassiana biocontrol agents from all over the country and the 3 white muscardine silkworms collected from Guangxi provincial silkworm rearing areas were identified by the morphological observation and molecular biology technology. The pathogenicity of B. bassaina to silkworms was determined, and the biological characteristics such as growth diameter, sporulation and the extracellular protease activity of the different B. bassiana strains were compared. [Result] The isolated 9 strains were all B. bassaina (Bals.) Vuillemin, and all strains had high pathogenicity to silkworm, but with different pathogenicities. The growth diameter, sporulation and extracellular protease activity of different B. bassiana strains were also different, and showed correlation with the patheogenicity to silkworms. [Conclusion] B. bassiana spores production amount and exocellular protease activity had significant positive correlation with their pathogenicity to silkworm.

    Full Text Available En las quebradas de Santa Elena y del Telégrafo, Uspallata, Precordillera mendocina, fueron descriptas rocas volcánicas de edad permotriásica, asignadas al Grupo Choiyoi. En este sector el grupo está representado por una secuencia volcánica, formada a partir de varios eventos piroclásticos de diferente magnitud, sucedidos en intervalos de tiempos cortos. Se reconocieron ochos eventos volcánicos, integrados por litofacies tales como flujos ignimbríticos parcialmente soldados, flujos ignimbríticos densamente soldados, vitrófiros y perlitas, oleadas piroclásticas y depósitos de caídas de tefras y cenizas. La composición determinada a través de observaciones petrográficas revela una acidificación creciente hacia las litofacies superiores, variando gradualmente de fenodacitas a riofenodacitas, finalizando con fenoriolitas. El esquema geológico definido para el área de estudio permite correlacionar dichas unidades con la Formación Horcajo, descripta para el valle del río de los Patos en la provincia de San Juan. Los espesores medidos disminuyen notablemente hacia el NNO y el SSE, lo que sugiere que los flujos se movilizaron canalizados en dirección NE-SO.

    We have investigated the microstructure of BxAl1-xN films grown by flow-modulated epitaxy at 1010 °C, with B/(B + Al) gas-flow ratios ranging from 0.06 to 0.18. The boron content obtained from X-ray diffraction (XRD) patterns ranges from x = 0.02 to 0.09. On the other hand, boron content deduced from the aluminum signal in the Rutherford backscattering spectra (RBS) ranges from x = 0.06 to 0.16, closely following the gas-flow ratios. Transmission electron microscopy indicates the sole presence of a wurtzite crystal structure in the BAlN films, and a tendency towards columnar growth for B/(B + Al) gas-flow ratios below 0.12. For higher ratios, the BAlN films exhibit a tendency towards twin formation and finer microstructure. Electron energy loss spectroscopy has been used to profile spatial variations in the composition of the films. The RBS data suggest that the incorporation of B is highly efficient for our growth method, while the XRD data indicate that the epitaxial growth may be limited by a solubility limit in the crystal phase at about 9%, for the range of B/(B + Al) gas-flow ratios that we have studied, which is significantly higher than previously thought.

    Full Text Available El texto de Aníbal Quijada Cerco de púas ejemplifica la doble vinculación de los testimonios del exilio chileno. Por una parte, éstos debieron inscribirse en las estrategias internacionales de denuncia contra la dictadura militar y, por otra, la comunidad cultural latinoamericana hizo de los testimonios un elemento esencial para la redefinición del concepto mismo de lo literario. El testimonio de Quijada desarrolla, en ese contexto, unas estrategias narrativas y de representación que alejan su textura de la mayoría de los testimonios de la época.The text of Aníbal Quijada Cerco de púas, is a good example of the double filiation of the testimonies of Chilean exile. In one hand these testimonies had a close relationship with the international protest against the military rule and, one the other hand, the cultural community made them appear as a main element in the crise of the concept of literature. The author focuses in the strategies used by the text of Quijada in that turbulent context.

    Full Text Available At the time Zeta was ruled by the local lords of the Balšić family, in the late fourteenth and the first half of the fifteenth century, the islets in Lake Scutari (Skadarsko jezero in Zeta were lively centres of monastic life. The paper looks at the forms of monastic life as suggested by the spatial organization and architecture of the monastic complexes founded by the Balšićs, and by the surviving written sources. The most important documentary source is the correspondence between Jelena Balšić and her spiritual father, Nikon, preserved in the manuscript known as Gorički zbornik (Gorica Collection. The letters show that Lake Scutari was a centre of monasticism touched by hesychast-inspired spirituality where both the eremitic and coenobitic ways of life were practised.

    Full Text Available OBJECTIVE: To compare 28-day mortality rates and clinical outcomes in ICU patients with ventilator-associated pneumonia according to the diagnostic strategy used. METHODS: This was a prospective randomized clinical trial. Of the 73 patients included in the study, 36 and 37 were randomized to undergo BAL or endotracheal aspiration (EA, respectively. Antibiotic therapy was based on guidelines and was adjusted according to the results of quantitative cultures. RESULTS: The 28-day mortality rate was similar in the BAL and EA groups (25.0% and 37.8%, respectively; p = 0.353. There were no differences between the groups regarding the duration of mechanical ventilation, antibiotic therapy, secondary complications, VAP recurrence, or length of ICU and hospital stay. Initial antibiotic therapy was deemed appropriate in 28 (77.8% and 30 (83.3% of the patients in the BAL and EA groups, respectively (p = 0.551. The 28-day mortality rate was not associated with the appropriateness of initial therapy in the BAL and EA groups (appropriate therapy: 35.7% vs. 43.3%; p = 0.553; and inappropriate therapy: 62.5% vs. 50.0%; p = 1.000. Previous use of antibiotics did not affect the culture yield in the EA or BAL group (p = 0.130 and p = 0.484, respectively. CONCLUSIONS: In the context of this study, the management of VAP patients, based on the results of quantitative endotracheal aspirate cultures, led to similar clinical outcomes to those obtained with the results of quantitative BAL fluid cultures.

    Full Text Available A riqueza do debate ocorrido entre os filósofos Luc Ferry e Marcel Gauchet, em janeiro de 1999, deu origem a este artigo, em que os autores exploram os temas e as questões discutidas naquela ocasião. O artigo apresenta as diferentes posições dos dois pensadores franceses, cuja preocupação maior é pensar as condições de possibilidade da religião e do religioso nos tempos atuais. Tempos em que, segundo os debatedores, predomina a individualização da crença e nos quais a presença de uma religiosidade sempre mais inquieta, difusa e incerta convive com o enfraquecimento institucional das religiões. Longe de desaparecer num universo cada vez mais laicizado, o religioso, como indagação sobre o sentido último da vida ou como aspiração ao absoluto, tende a permanecer como um substrato insuperável. Como, então, pensar o religioso após a religião? O texto apresenta as diferentes e divergentes posições de Ferry e Gauchet acerca da pertinência do uso de termos clássicos como "sagrado", "divino", "transcendente", dentre outros, para tratar os constituintes dessa religiosidade contemporânea e inquieta, própria de uma época na qual se torna impossível a edificação de um mundo de parte a parte estruturado pela religião e na qual o religioso impregnaria todos os setores da vida pública e privada. Palavras-chave: Religião; Religiosidade; Secularização; Autonomia; Heteronomia.   Abstract This paper analyses the questions and problems that was discussed during an important debate between the French philosophers Marcel Gauchet and Luc Ferry, which take place at Paris on January, 1999.

    San Cristóbal volcano in northwest Nicaragua is one of the most active basaltic-andesitic stratovolcanoes of the Central American Volcanic Arc (CAVA). Here we provide novel constraints on the volcano's magmatic plumbing system, by presenting the first direct measurements of major volatile contents in mafic-to-intermediate glass inclusions from Holocene and historic-present volcanic activity. Olivine-hosted (forsterite [Fo] 1500 μg/g) found in Nicaragua at Cerro Negro, Nejapa, and Granada. Models of H2O and CO2 solubilities constrain the degassing pathway of magmas up to 425 MPa ( 16 km depth), which includes a deep CO2 degassing step (only partially preserved in the MI record), followed by coupled degassing of H2O and S plus crystal fractionation at magma volatile saturation pressures from ∼ 195 to < 10 MPa. The variation in volatile contents from San Cristóbal MI is interpreted to reflect (1) Holocene eruptive cycles characterized by the rapid emplacement of basaltic magma batches, saturated in volatiles, at depths of 3.8-7.4 km, and (2) the ascent of more-differentiated and cogenetic volatile-poor basaltic andesites during historic-present eruptions, having longer residence times in the shallowest (< 3.4 km) and hence coolest regions of the magmatic plumbing system. We also report the first measurements of the compositions of noble-gas isotopes (He, Ne, and Ar) in fluid inclusions in olivine and pyroxene crystals. While the measured 40Ar/36Ar ratios (300-304) and 4He/20Ne ratios (9-373) indicate some degree of air contamination, the 3He/4He ratios (7.01-7.20 Ra) support a common mantle source for Holocene basalts and historic-present basaltic andesites. The magmatic source is interpreted as generated by a primitive MORB-like mantle, that is influenced to variable extents by distinct slab fluid components for basalts (Ba/La 76 and U/Th 0.8) and basaltic andesites (Ba/La 86 and U/Th 1.0) in addition to effects of magma differentiation. These values for the

    Full Text Available In this article the author makes a comparative analysis of two concepts of social finalism formulated with the difference of fifty years. Researchers consider.both authors to be esoteric thinkers. Daniel Andreev was fascinated with the doctrine of Elena Blavatskaya. That’s the main reason why the finalistic concepts of the above-mentioned authors are examined as interrelated ones. The definition of «social finalism» is given in the article. According to classical interpretation of the concept, finalism (from Lat. Finalis means final, being the final goal. So, under this concept the author understands the achievement of a certain final level of social development, according to the goals. Each thinker offers his/her own goals and ways of achieving, the analysis of finalistic concepts helps to identify the most common and often allocated by philosophers, and hence universal goals, ways, means and conditions; which are, in our opinion, the ones reflecting the true preferences of mankind in the choice of the future for people themselves and their descendants. In this case, the esoteric concepts are analyzed. This fact in the author’s opinion is quite relevant, since the number of people who position themselves as adherents of esoteric teachings is steadily increasing. In the social finalistic concept of Blavatskaya the purpose – «brotherhood of all mankind», means of achieving – the Duty, Mercy, Self-sacrifice, and obstacles to the achievement of the final stage of society today are considered. The article shows that all necessary changes to achieve the ideal state of society, according to Andreev, should be carried out in all spheres of public life. This study will help to understand the aspirations and hopes for social transformations of people practicing esoteric approach to the perception of life.

    Full Text Available The expansion of human activities on the quest for development causes an increase in generation of waste which can be reused, in most cases, as inputs to other economic activities, making them more sustainable. In this sense, the research aimed to analyze the environmental and economical conditions that favor the production of electricity from the use of wood waste generated in the municipality of Marcelândia-MT. For that, the existing waste stocks in this county were quantified from data provided by the Ministry of Environment. Then, by the statistical method, the time of extraction of the total area covered by vegetation in the city was estimated. Finally, the costs and revenues were analized to demonstrate the profitability of the establishment of a thermal power plant. It was found that in Marcelândia-MT, the wood waste generated between May 2007 and June 2012 add up to 8,914,743.13 m3. In this municipality, there are 18 forest managements, amounting to 15,935,080 m3, with the potential to be exploited in a managed way for at least 189 years. Considering in this scenario, the average utilization of total log (58.54% would have a complete generation of 6,606,684.57 m3 of wood waste, enough to sustain a thermal power plant for about 43 years, this without considering the waste generated in the continuity of timber production and those generated by forest, which would be enough to supply a plant for a period of 32 years. The use of wood waste generated in Marcelândia-MT as input of the power plant is presented as a viable proposal, with internal rate of return close to the minimum expected rate of attractiveness, positive net present value and return on investment from the sixth year, with income of R$ 13,240,654.00. In this way, the city’s energy demand (1,382,268 kWh could be supplied by the power plant and the generated surplus power could be marketed.

Entre los muchos méritos del estudio de Ponce se pueden destacar tres en particular. En primer lugar, el análisis de Ponce pone de manifiesto que el humanismo del Renacimiento (“humanismo burgués” no sólo se ha prestado a usos ideológicos, sino que surgió por primera vez precisamente en la forma de una ideología. En segundo lugar, pone de manifiesto la necesidad de precisar el tipo de humanismo que uno reivindica al invocar este concepto. Por último, nos recuerda que un humanismo realmente emancipador no es posible si no se dan determinadas condiciones históricas y sociales.

    A new blue-emitting phosphor of Eu{sup 2+}-activated hexa-aluminate CaZrBAl{sub 9}O{sub 18} was synthesized by a conventional solid-state reaction method. The crystalline phase formation was confirmed by X-ray powder diffraction (XRD) measurements. The photoluminescence excitation and emission spectra, the luminescence decay curves and the time-resolved spectra of CaZrBAl{sub 9}O{sub 18}:Eu{sup 2+} were taken to investigate the luminescence characteristics. The dependence of CaZrBAl{sub 9}O{sub 18}:Eu{sup 2+} luminescence intensity on the Eu{sup 2+} doping concentrations was investigated. This phosphor can be efficiently excited by UV light and presents blue luminescence. There is one kind of Eu{sup 2+} luminescence center in the lattices, which was confirmed by the time-resolved luminescence spectra. The temperature-dependent luminescence intensity was measured and the activation energy (ΔE) for thermal quenching was reported. The phosphor shows high luminescence intensity and an excellent thermal stability on temperature quenching. Eu{sup 2+}-doped hexa-aluminate CaZrBAl{sub 9}O{sub 18} presents bright blue-emitting luminescence with high thermal quenching; only one Eu{sup 2+} center was confirmed in this hexa-aluminate lattices.

    Full Text Available The process of interstitial inflammation, often chronic, goes fluently from alveolitis through granuloma formation to irreversible fibrosis and lung remodeling. Eventually, the loss of functional alveolar units leads to chronic respiratory failure. The pneumoproteins (e.g. SP-D, CC-16 are considered to be markers of interstitial inflammation. We measured BAL concentration of SP-D, CC-16 and IL-10 in patients with sarcoidosis (27, IPF (7 and HP (9. The level of each marker was determined by ELISA specific kit. We found the highest SP-D and CC-16 BAL concentration in patients with the III stage of sarcoidosis (96,67 ng/ml and 31,78 ng/ml, respectively. The lowest SP-D concentration was observed in patients with IPF (76,49 ng/ml, and the lowest CC-16 concentration in patients with HP (21,39 ng/ml. The differences were not statistically significant. In the group of the III stage of sarcoidosis higher SP-D levels were related to higher BAL cytosis and higher percentage of BAL neutrophils, just the opposite as in the IPF and HP group. In the III stage of sarcoidosis and HP, the lower SP-D levels, the lower FEV1 and VC values.

    Pathogenicity of the fungi Metarrhizium anisopliae (Metsch.) Sorokin and Beauveria bassiana (Bals.) Vuillemin to stink bug Scaptocoris carvalhoi Becker, 1967 was evaluated under laboratory and greenhouse conditions. Experiments were carried out at EMBRAPA Agropecuaria Oeste, Dourados, Mato Grosso do Sul State, Brazil, in 2003. Ten M. anisopliae and eleven B. bassiana isolates were evaluated in laboratory using a completely randomized experimental design with five replicates (10 adults and 5 nymphs/plot). The pathogenicity of M. anisopliae isolate (Ma69) was also separately evaluated against nymphs and adults in laboratory and greenhouse. The stink bug mortality levels were higher for M. anisopliae isolates (between 73.3% and 94.7% than for B. bassiana isolates (between 10.7% and 78.7%). In greenhouse, stink bug mortality due to the M. anisopliae isolate (Ma69) was 57.3%, and there was no difference of mortality for nymphs and adults of stink bug in laboratory. However, in greenhouse, mortality levels were significantly higher (p<0,05) for nymphs (38,4%) than for adults (16,2%). From these data, we conclude that M. anisopliae isolate Ma69 was efficient to control S. carvalhoi in laboratory and in greenhouse, thus being a promising choice for use as a microbial insecticide under field conditions.

    Aflatoxins, the secondary metabolites produced by species of naturally occurring Aspergilli, are commonly found in food such as cereals, dried fruits and juice, wine, beer and spices. They are hepatotoxic and are well known human carcinogens based on evidence from human studies. Aflatoxins are an environmental risk factor for the development of hepatocellular carcinoma (HCC). Chronic hepatitis B-infected patients are at increased risk of cirrhosis, hepatic failure and liver cancer. This study was designed to determine the serum aflatoxin B1 (AFB1 ), aflatoxin B2 (AFB2 ), aflatoxin G1 (AFG1 ) and aflatoxin G2 (AFG2 ) concentrations using high-pressure liquid chromatography (HPLC) in hepatitis B-infected patients with or without cirrhosis and liver cancer, alongside healthy controls in Balıkesir, Turkey. The mean AFB1 and total AF levels in patients without liver cancer and cirrhosis were significantly higher than healthy controls. The mean AFB1 and total AF levels in patients with chronic hepatitis B and HCC were significantly higher than infected patients with or without cirrhosis. These results suggest that patients with chronic hepatitis B who are exposed to AFs are at increased risk for developing HCC, which might be prevented by reducing consumption of contaminated foods. © 2015 John Wiley & Sons Ltd.

    We report on the first detection of extreme-ultraviolet (EUV) absorption variability in the NeVIII 770,780 mini-broad absorption line (mini-BAL) in the spectrum of the quasar (QSO) PG 1206+459. The observed equivalent width (EW) of the NeVIII doublet show a ~4 sigma variation over a timescale of 2.8 months in the QSO's rest-frame. Both members of the NeVIII doublet exhibit non-black saturation, indicating partial coverage of the continuum source. An increase in the NeVIII covering fraction from f_c = 0.59\\pm0.05 to 0.72\\pm0.03 is observed over the same period. The NeVIII profiles are too highly saturated to be susceptible to changes in the ionization state of the absorbing gas. In fact, we do not observe any significant variation in the EW and/or column density after correcting the spectra for partial coverage. We, thus, propose transverse motions of the absorbing gas being the cause of the observed variability. Using a simple model of a transiting cloud we estimate a transverse speed of ~1800 km/s.

A glândula metapleural (GMP é uma estrutura exógena, encontrada apenas nos formicídeos, sendo mais desenvolvida nas fêmeas e operárias, enquanto nos machos ou está atrofiada ou não existe. Tem sido sugerido várias possíveis funções para a secreção produzida por esta glândula, sendo a hipótese de efeito protetor contra entomopatógenos a mais estudada. Para testar esta hipótese, foi aplicada uma suspensão de conídios (1,30 x 106 de Beauveria bassiana (Bals. Vuill. nas GMP e na porção ântero-superior do metatórax (ASM de fêmeas aladas de Acromyrmex laticeps (Forel, enquanto nos machos a suspensão foi aplicada apenas na porção ASM, pois estes não apresentam o átrio característico da GMP. Os resultados obtidos indicaram que a secreção metapleural das fêmeas desta espécie não possui efeito fungicida sobre B. bassiana, e que tanto os machos como as fêmeas alados são sensíveis a este fungo entomopatogênico.

    Full Text Available The German naturalist Juan Cristóbal Gundlach (1810–1896 conducted, while a resident of Cuba, two expeditions to Puerto Rico in 1873 and 1875–6, where he explored the southwestern, western, and northeastern regions of this island. Gundlach made representative collections of the island’s fauna, which formed the nucleus of the first natural history museums in Puerto Rico. When the natural history museums closed, only a few specimens were passed to other institutions, including foreign museums. None of Gundlach’s and few of his contemporaries’ specimens have survived in Puerto Rico. We located 191 bird specimens (43 species collected there by Gundlach, all of which are in foreign institutions, especially Museum für Naturkunde Berlin. Here we list all located specimens and include data associated with them. Six new species were described out of the Gundlach collections from Puerto Rico, three of which are still taxonomically recognized today. Information about the types of those taxa is given.

    The wide-ranging physiology and large genetic variability observed for prokaryotes is largely attributed, not to the prokaryotic genome itself, but rather to mechanisms of lateral gene transfer. Cassette PCR has been used to sample the integron/gene cassette metagenome from different natural environments without laboratory cultivation of the host organism, and without prior knowledge of any target protein sequence. Since over 90% of cassette genes are unrelated to any sequence in the current databases, it is not clear whether these genes code for folded functional proteins. We have selected a sample of eight cassette-encoded genes with no known homologs; five have been isolated as soluble protein products and shown by biophysical techniques to be folded. In solution, at least three of these proteins organise as stable oligomeric assemblies. The tertiary structure of one of these, Bal32a derived from a contaminated soil site, has been solved by X-ray crystallography to 1.8 A resolution. From the three-dimensional structure, Bal32a is found to be a member of the highly adaptable alpha+beta barrel family of transport proteins and enzymes. In Bal32a, the barrel cavity is unusually deep and inaccessible to solvent. Polar side-chains in its interior are reminiscent of catalytic sites of limonene-1,2-epoxide hydrolase and nogalonic acid methyl ester cyclase. These studies demonstrate the viability of direct sampling of mobile DNA as a route for the discovery of novel proteins.

    An equiatomic FeSiBAlNi amorphous high-entropy alloy (HEA) was fabricated by mechanical alloying (MA). A fully amorphous phase was obtained in the FeSiBAlNi HEA after 240 h of MA. The bulk FeSiBAlNi samples were sintered by spark plasma sintering (SPS) at 520 and 1080°C under a pressure of 80 MPa. The sample sintered at 520°C exhibited an amorphous composite structure comprising solid-solution phases (body-centered cubic (bcc) and face-centered cubic (fcc) phases). When the as-milled amorphous HEA was consolidated at 1080°C, another fcc phase appeared and the amorphous phase disappeared. The sample sintered by SPS at 1080°C exhibited a slightly higher melting temperature compared with those of the as-milled alloy and the bulk sample sintered at 520°C. The corrosion behaviors of the as-sintered samples were investigated by potentiodynamic polarization measurements and immersion tests in seawater solution. The results showed that the HEA obtained by SPS at 1080°C exhibited better corrosion resistance than that obtained by SPS at 520°C.

  13. Investigating Magmatic Processes on San Cristóbal, Galápagos Through Analysis and Modeling of Newly Acquired Gravity Measurements

    San Cristóbal, in the eastern Galápagos, is one of the oldest islands formed by the same magmatic system currently responsible for volcanic activity in the western archipelago. Unlike the younger western islands, San Cristóbal lacks any morphological evidence of a caldera, which is a characteristic feature of the western Galápagos shield volcanoes. Instead, San Cristóbal consists of two shield complexes dominated by eruptive cones aligned along presumed fissure systems. The island thus provides an opportunity to investigate whether the dichotomy between the morphology of the western and eastern Galápagos volcanoes is a result of evolving magmatic systems or a fundamentally different set of formation processes. We are reporting the results of a recent gravitational survey on San Cristóbal's southwestern shield, which consists of 186 measurements at 500 m spacing along all passable roads. Our results indicate that the Bouguer Anomaly (BA) on the southwest shield of San Cristóbal has a range of 8 mGals. The BA has a relative low along the western part of the shield complex and a relative high in the central and eastern sections. Within the central complex, there is a prominent BA low, which corresponds to a large cone. These results contrast with previous studies performed on the western volcanoes of Fernandina and Sierra Negra (Case et al., 1974; Vigouroux et al., 2008), which exhibit a 30 mGal BA high centered over each caldera. On these volcanoes, the BA high was interpreted as a dense plug of cumulates in the magmatic system beneath the volcano's caldera. Though our results differ from those obtained in the western Galápagos, a study by Schwartz et al.(2014) on the eastern island of Santa Cruz also fails to identify a prominent gravity high. Schwartz et al. concluded that a low magma supply to older islands cannot support the caldera formation process that characterizes the western islands, which are believed to form by evacuation of shallow magma sills

    Full Text Available This work tries to demonstrate that the social construction of the national hero/heroine as a symbol of courage and resistance generally arises within a period of social, political, and economic crisis. The national hero is a construction that is created in a moment characterized by the loss of public trust and the failure of government leaders to act. The creation of the heroic image functions as a sociopolitical tool. The article suggests that there is a close relationship between the history and the construction of heroic fgures. Using the death of Peruvian activist María Elena Moyano as a concrete example, it demonstrates that journalistic discourse has the ability to create an heroic image around a person who has been given the traditional role that the hero has played in society since Antiquity.

    Full Text Available Fifty strains of the entomopathogenic fungi Beauveria bassiana (Bals. Vuill. and Metarhizium anisopliae (Metsch. Sorok. were tested against the termite Cornitermes cumulans. In the first phase of the experiments, several bioassays were conducted and the five best strains were selected. The criterion for strain selection during this phase was the confirmed mortality above 50% five days after application of the fungus. Three M. anisopliae and two B. bassiana strains were the most virulent. The second phase of the experiments consisted of a bioassay and a conidial production test using a rice medium. The best M. anisopliae and B. bassiana strains were selected using both the confirmed insect mortality nine days after application of the fungus and the yield of conidia.

    Multiple sclerosis (MS), neuromyelitis optica (NMO), and Baló's disease (BD) are inflammatory demyelinating diseases of the CNS. We previously reported anti-aquaporin-4 (anti-AQP4) antibody-dependent AQP4 loss occurs in some NMO patients, while antibody-independent AQP4 astrocytopathy can occur in heterogeneous demyelinating conditions, including MS, NMO and BD. To investigate the relationship between astrocytopathy and demyelination, we focused on connexins (Cxs), which form gap junctions (GJs) between astrocytes and oligodendrocytes and maintain homeostasis in the CNS. We evaluated expression of astrocytic Cx43/Cx30 and oligodendrocytic Cx47/Cx32 in autopsied materials from MS, NMO and BD patients. Astrocytic Cx43 and oligodendrocytic Cx32/Cx47 expressions were significantly diminished in both demyelinated and preserved myelin layers in all BD samples. In the leading edge of BD lesions, Cx43 and AQP4 loss preceded Cx32/Cx47 loss. Half of the NMO and MS samples showed preferential loss of astrocytic Cx43 expression in actively demyelinating and chronic active lesions, where heterotypic Cx43/Cx47 astrocyte-oligodendrocyte GJs were lost. Cases with Cx43 loss were significantly associated with rapid disease progression, regardless of the disease phenotype. Pathologically, Cx43 loss was frequently accompanied by distal oligodendrogliopathy. Our findings suggest that Cx43 astrocytopathy can occur in MS, BD and NMO. Moreover, astrocytic Cx43 loss may be associated with disease aggressiveness and distal oligodendrogliopathy in demyelinating conditions. Early disruption of glial communications via GJs may cause loss of glia syncytium, thereby inducing oligodendroglial damage and myelin loss. Inhibition of Cx hemichannels and restoration of GJs may be a possible therapeutic target for demyelinating disorders. © 2015 Japanese Society of Neuropathology.

    The Liber de arte medendi (Lyon, 1564) is the most relevant book of Prima Professor of The Faculty of Medicine of Universidad de Alcalá, doctor Cristóbal de Vega (1510-1573). It is a treatise--674 pages in folio--of theoretical and practical medicine. This doctrinal expose, scholar and bookisk, changes its tone in the second of the three parts, the liber II, that deals with "no natural things" of galenism, which necessarily affect the organism and that, depending on how they are used, they may strengthen or weaken its health: air, physical activity, foods and drinks, sleep, evacuations and passions of the soul. Within the section dedicated to foods and drinks, we have studied the interesting chapter about wines, where the author makes a hygienic assessment about wine. The chapter on spanish wines consigned at the Liber de arte medendi and some other references about the therapeutic capabilities of some of the wines described by the author. He we undertaken a critical analysis of that chapter, glossing the most significant texts about spanish wines mentioned by the author. In this chapter vega praises the class and hygienic applications of white Alcarrian wines from Yepes, Lillo and Santorcaz, of the Galician from Rivadavia, from Cantalapiedra in the Salamanca region, and the Andalusians from Jerez, Cazalla and Alanís. He also extols the smooth reds from Santorcaz; though the best in this category would be, for the adaptation of its temperament to the human nature, the Illana wine. at Liber de arte medendi, wines from Cantalapiedra (Ded Castille), Rivadavia (Galicia), Jerez, Ca- zalla and Alanís (Andalusia), Santorcaz, Corpa, Yepes, San Martín de Valdeiglesias, Villalbilla, Illana and Lillo (New Castille) are mentioned.

    Marcel Duchamp,the most famous figure of avant-garde artists,has changed the direction of art development in 20th century and broken the principles of modern systems of art.His works have become the examples and illustrations when aestheticians rethought what art was.So Duchamp and his works are worthy and important.Importantly,the process that Duchamp deserved his right situation in art history and the process that the nature of avant-garde art has transformed were the same one.%作为早期先锋派的代表人物,杜尚的创作打破了传统艺术观念的诸种规定,启发美学家们对艺术的本质与定义问题进行重新思考,因而具有重要的艺术史价值。然而,杜尚艺术史地位确立的过程,同时也是先锋艺术自身性质蜕变的过程,先锋派在巨大的成功中走向了自己的对立面。

Or, bien plus fréquemment, le film s’offre comme un substitut de roman à un spectateur qui ne l’a pas lu. Adoptant une approche pragmatique, l’article qui suit pose ces questions à propos de deux adaptations de Madame Bovary : à quoi reconnaît-on qu’un récit filmique est non seulement une transposition audiovisuelle des signes écrits, mais aussi une lecture de ceux-ci ?

    Full Text Available A current tendency in Spanish Golden Age theatre studies is dramatic segmentation. In this sense, we must emphasize Marc Vitseʼs methodology, which suggests structuring the play according to the versification changes. We are going to put into practice this theory with a work by an unknown playwright: Renegado, rey y mártir by Cristóbal de Morales. We will verify that versification does actually help when dividing and hierarchising the different moments of the play. At Renegado, rey y mártir violence is important due to the fact that it causes the strophic changes and structures the plot.

  10. Toxicity induced by Hg2+ on choline acetyltransferase activity from E. electricus (L.) electrocytes: the protective effect of 2,3 dimercapto-propanol (BAL).

    2005-04-01

    The effect of mercury (Hg(2+)) on the activity of choline acetyltransferase (ChAT) from electrocytes of Electrophorus electricus (L.) was studied due to the importance of this enzyme and acetylcholine in many neurochemical functions such as arousal, learning, and memory. Mercury, which has affinity to thiol groups, acted as a potent inhibitor of ChAT, which was obtained by differential centrifugation and ammonium sulfate precipitation, at 80%, from the main electric organ homogenate. Mercury inhibition presents different kinetic behaviors for both enzyme substrates: noncompetitive to choline and of mixed type to AcCoA, with inhibition constants on the order of 0.5 to 1.0 microM. The enzyme activity was recovered using 2,3 dimercapto-propanol (BAL), a well-known chelate for sulphydryl groups and metals, which acted as a protecting agent and was able to revert the Hg(2+) inhibition at a concentration of 10 (-6) M. After treatment with this metal and in the presence of 2,3 dimercapto-propanol, 70% of the enzyme activity was recovered for AcCoA and 80% for choline. The observed inhibition is likely due to direct protein interaction, because the addition of BAL reversed the effects of HgCl(2) on ChAT activity. The results cast new light on the mechanisms of mercurial neurotoxicity.

    Full Text Available This work aims to understand the organizational strategies used by the ballet company Grupo Corpo, based in Belo Horizonte, Minas Gerais, Brazil. It is based upon the premise that such practices are configured (in this organization’s daily management practices. In order to achieve the proposed objective, four questions considered to be recursive in this field were used as guidelines: (a What is strategy? (b Who is the strategist? (c What do strategists do? (d What can explain an analysis of strategists and their actions? As methodological support, an ethnography was conducted. In addition, the Grounded Theory procedure was used to develop the proposal of bringing about a substantial concept of strategy. A situational analysis was also done (Clarke, 2005 and at the end of the study, three organizational spheres within the Corpo de Balé group: its Ballet Group sphere, its Citizen sphere, and its Dance School sphere. The practices and relationships constructed between these and the subjects that actually included them in the organization under study were also identified. Thus, a relational scheme was established, involving the observed practices and the individual and collective actors. Based on the analysis of the relational scheme a strategy concept was elaborated for the Corpo de Balé group.

    Jáuregui, Carlos A.

    2015-12-01

    Full Text Available Oswaldo Costa was a key member of the Brazilian modernist Antropofagia (Anthropophagy movement of the late 1920s, yet he has been largely forgotten by critics and marginalized from national cultural history. Costa articulated —as no other member of the movement did, including his famous leader Oswald de Andrade— an Antropofagia intellectually engaged in what we call a cannibal critique of colonial modernity and Occidentalism. Costa’s Antropofagia cannibalized the historical archive, reading against the grain of a triumphant Western imperial history. Throughout his contributions to the Revista de Antropofagia, he questioned Brazil’s cultural allegiance to Europe, pointed out the existence of asynchronous temporalities within Brazil, and defied Eurocentric notions of civilization and progress that ideologically structure Brazilian nationalism in the ninetieth and twentieth centuries. He also enacted an anthropophagous re-reading of Brazilian historiography against its celebration of colonialism and proposed the necessity of a cultural decolonization. This article analyzes Costa’s principal contributions to Antropofagia and rescues his hitherto overlooked countercolonial thought from the oblivion of collective forgetting. Moreover, it examines Costa’s significant view of Brazilian modernity as a perfidious armistice with other barbarous temporalities, and of the Westernization of Brazil as a deceptive appearance that hides ever-present colonial antagonisms.Oswaldo Costa fue un miembro fundamental del movimiento modernista Antropofagia de finales de la década de 1920. Pese al olvido crítico de su obra y a su exclusión de la historia cultural brasileña, Costa articuló —como acaso ningún otro miembro del movimiento, incluyendo a su famoso líder Oswald de Andrade— una Antropofagia-otra, intelectualmente trabada en lo que denominamos una crítica caníbal de la modernidad colonial y del Occidentalismo.

    Full Text Available The present article seeks to show that, for the Dadaists, film was an unsatisfying medium because as a technically reproduced artifact it counteracted Dada’s sense of immediacy. The focus of my text revolves around the notion of “facticity” inspired by Wieland Herzfelde, for whom Dada represented a reaction to all attempts at disavowing the “factual.” Manifestations of Dada, such as the readymade, live performance, collage, photomontage and not least the photogram, attest to a radically new understanding of realism in art, adhering to an “anti-mimetic concept of realism” (Elsaesser. As I will argue, Dada did not capitulate to film, but made a ‘compromise,’ by exploring different strategies to reinsert the “factual“ into this medium of reproduction. This could be done by (1 turning a screening into a live performance, (2 eliciting a bodily reaction in the spectator, (3 experimenting with hand-made, camera-less devices of film making, and (4 calling to mind the material existence of the cinematic apparatus. What these strategies have in common is to minimalize (although not necessarily to abolish the distance between “reality” and its representation in order to maintain film’s initial tactility, as described by Walter Benjamin in “The Work of Art in the Age of Mechanical Reproduction.” Man Ray’s Le Retour à la raison (1923 and Marcel Duchamp’s Anémic cinéma (1924–26 are prototypes of the Dadaist ‘compromise.’ A similar impetus can be found in a more recent example, Dream Work (2001, the third part of Peter Tscherkassky’s CinemaScope-Trilogy, which explicitly refers to the early days of French experimental film. What these three films, despite their differences, have in common, is to privilege a certain immediacy (be it during the moment of production or during the moment of reception and to include an element of tactility, usually absent from cinematic works.

    Phlomis linearis Boiss. & Bal. of the Lamiaceae family growing in central, east and southeast Anatolia is an endemic species for Turkey. The essential oil obtained from the aerial parts by hydro distillation was subsequently analyzed by GC/MS. The main components of the oil were found as beta-caryophyllene (24.2%), germacrene D (22.3%) and caryophyllene oxide (9.2%), among 49 identified compounds, representing 94.5% of the total essential oil. The overall biological activity of the essential oil (100 microg/pellet) was tested on the chorioallantoic membrane (CAM) of the fertilized hen's egg in order to examine the anti-angiogenic and anti-inflammatory activity. None of the tests showed pronounced activity, toxicity or irritation at the tested concentration.

La sobrevaloración de los saberes masculinos, la expectativa de formar una unión como mandato social y como estrategia de sobrevivencia, así como la violencia que sufren las mujeres a lo largo de su ciclo de vida, condicionan su aceptación de relaciones sexuales con escasa protección anticonceptiva.

    Full Text Available EI siglo XVI asiste a una secularización que conduce al redescubrimiento del cuerpo humane y con ello al interés por conservar la salud. En este contexto histórico, la obra de Cristóbal Méndez resulta apasionante por ser la primera que trata el ejercicio como una herramienta para mejorar la salud del cuerpo y con ello la del alma. Pone el libro en manos de sus lectores con una doble intención: mostrar los grandes beneficios que se derivan de la práctica del ejercicio físico y orientar esta práctica en función de diferentes factores; es decir, la edad, el sexo, el clima, los lugares, la época del año, etc., ofreciendo consejos de uso e insistiendo en su importancia en cada etapa de la vida y en el tratamiento de enfermedades.------------------------------------------------------------------------------During the 16th century an increasing secularisation leads to a rediscovery of human body and subsequently to the interest in health maintenance. In such a historical context, Cristóbal Méndez´ work is fascinating for being the first one dealing with physical exercise as a means to improve the health of the body and hence that of the soul. He writes his book with a twofold aim: to show the great benefits obtained through the practice of physical exercise and to advise on such practice according to different factors, such as age, gender climate, season of the year, etc., offering tips for use and insisting on its importance for each stage and for the treatment of illnesses.

    Full Text Available In this paper, the interesting and significant chapter on the bloodletting, included in the medical treatise entitled the Liber de arte medendi (1564 of Cristóbal de Vega (1510-1573, has been studied. His doctrine, mainly with regard to the morbus lateralis, supports the proper one from the most of the sixteenth century authors belonging to the medical humanism: a copious bloodletting in the elbow`s flexure of the homolateral arm. In addition to the Vesalius’ anatomical contributions on the venous tree recorded in that chapter, Vega has a debate on certain controversial aspects with the contemporary doctors Argenterio and Fuchs. In spite of his fidelity to the galenism, Vega shows some practical disagreements concerning its use in children, pregnant women and its achievement up to fainting.

    Au/H similarity is a hot topic in chemistry. Here, we report the theoretical prediction of new members of the Au/H analogy family:covalent B2Au4, ionic Al2Au4, and BAlAu4. A comparative study of the geometric and electronic structures of electron-deficient B2Au4, Al2Au4, and BAlAu4 was performed based on density and wave functional theories. Detailed orbital analyses, adaptive natural density partitioning (AdNDP), and electron localization function (ELF) analyses were performed. Ab initio theoretical evidence strongly suggests that the ground state of slightly distorted C2 B2Au4 is a covalent complex containing two B―Au―B three centers-two electrons (3c-2e) bonds. Unexpectedly, C3v Al+(AlAu4)-and C3v Al+(BAu4)-are predicted to have a salt-like composition with three X―Au―Al 3c-2e bonds (X=Al in Al2Au4, X=B in BAlAu4). Al2Au4 and BAlAu4 represent the first examples of bridging gold bonds in ionic-deficient systems. The adiabatic and vertical detachment energies of the anions were calculated to facilitate their future experimental characterization. Bridging gold addressed in this work provides an interesting bonding mode for covalent and ionic-deficient systems, and may aid in designing new materials and catalysts with highly dispersed Au atoms.%Au/H相似性的研究是现代化学中的一个热门话题.我们从理论上报道Au/H相似的新成员:共价化合物B2Au4,离子化合物Al2Au4和BAlAu4.采用密度泛函和波函数理论方法对比研究了缺电子体系B2Au4、Al2Au4和BAlAu4的几何和电子结构.详细讨论了它们基态结构的轨道、适应性自然密度划分(AdNDP)和电子局域函数(ELF)分析.计算结果表明稍微扭曲变形的C2 B2Au4是基态结构,在这个共价化合物中含有两个B―Au―B三中心二电子(3c-2e)键.然而C3v Al+(AlAu4)-和C3v Al+(BAu4)-被研究证明是含有三个X―Au―Al三中心二电子键的类盐化合物(在Al2Au4中X=Al, BAlAu4中X=B).

    We sought to identify cells and cytokines in bronchoalveolar lavage (BAL) fluids that distinguish asthma from healthy control subjects and those that distinguish controlled asthma from uncontrolled asthma. Following informed consent, 36 human subjects were recruited for this study. These included 11 healthy control subjects, 15 subjects with controlled asthma with FEV1≥80% predicted and 10 subjects with uncontrolled asthma with FEV1 cytokines were measured in these fluids. Compared to healthy control subjects, patients with asthma had significantly more percentages of eosinophils and neutrophils, IL-1RA, IL-1α, IL-1β, IL-2Rα, IL-5, IL-6, IL-7, IL-8, G-CSF, GROα (CXCL1), MIP-1β (CCL4), MIG (CXCL9), RANTES (CCL5) and TRAIL in their BAL fluids. The only inflammatory markers that distinguished controlled asthma from uncontrolled asthma were neutrophil percentage and IL-8 levels, and both were inversely correlated with FEV1. We examined whether grouping asthma subjects on the basis of BAL eosinophil % or neutrophil % could identify specific cytokine profiles. The only differences between neutrophil-normal asthma (neutrophil≤2.4%) and neutrophil-high asthma (neutrophils%>2.4%) were a higher BAL fluid IL-8 levels, and a lower FEV1 in the latter group. By contrast, compared to eosinophil-normal asthma (eosinophils≤0.3%), eosinophil-high asthma (eosinophils>0.3%) had higher levels of IL-5, IL-13, IL-16, and PDGF-bb, but same neutrophil percentage, IL-8, and FEV1. Our results identify neutrophils and IL-8 are the only inflammatory components in BAL fluids that distinguish controlled asthma from uncontrolled asthma, and both correlate inversely with FEV1.

    ♦ Background: A multicenter, multi-country randomized controlled trial (the balANZ study) recently reported that peritonitis rates significantly improved with the use of neutral-pH peritoneal dialysis (PD) solutions low in glucose degradation products (“biocompatible”) compared with standard solutions. The present paper reports a secondary outcome analysis of the balANZ trial with respect to peritonitis microbiology, treatment, and outcomes. ♦ Methods: Adult incident PD patients with residual renal function were randomized to receive either biocompatible or conventional (control) PD solutions for 2 years. ♦ Results: The safety population analysis for peritonitis included 91 patients in each group. The unadjusted geometric mean peritonitis rates in those groups were 0.30 [95% confidence interval (CI): 0.22 to 0.41] episodes per patient-year for the biocompatible group and 0.49 (95% CI: 0.39 to 0.62) episodes per patient-year for the control group [incidence rate ratio (IRR): 0.61; 95% CI: 0.41 to 0.90; p = 0.01]. When specific causative organisms were examined, the rates of culture-negative, gram-positive, gram-negative, and polymicrobial peritonitis episodes were not significantly different between the biocompatible and control groups, although the biocompatible group did experience a significantly lower rate of non-pseudomonal gram-negative peritonitis (IRR: 0.41; 95% CI: 0.18 to 0.92; p = 0.03). Initial empiric antibiotic regimens were comparable between the groups. Biocompatible fluid use did not significantly reduce the risk of peritonitis-associated hospitalization (adjusted odds ratio: 0.80; 95% CI: 0.48 to 1.34), but did result in a shorter median duration of peritonitis-associated hospitalization (6 days vs 11 days, p = 0.05). Peritonitis severity was more likely to be rated as mild in the biocompatible group (37% vs 10%, p = 0.001). Overall peritonitis-associated technique failures and peritonitis-related deaths were comparable in the two groups

    2014-11-01

    Active tectonics of central Anatolia is mainly governed by the collision of the African, Arabian and Anatolian plates, which causes westward escape of Anatolia along the North and East Anatolian Fault zones, and the counterclockwise rotation of the Kırşehir block with insignificant internal deformation. The formation of the present-day tectonic processes in this region can be deduced from geophysical prospecting and seismological data. Although the seismicity in central Anatolia is distinctively lower than that in the northern and eastern parts of the Anatolian plate, small and moderate earthquakes (2.5 ≤ Mw ≤ 6.0) mostly occurred in the region in the past decades or so. For example, intense earthquake activity was observed in the Balâ-Afşar-Sırapınar (Ankara, central Anatolia) region in the period of 2005 to 2008 with destructive earthquakes of July 30, 2005 (Mw = 5.2); December 20, 2007 (Mw = 5.7) and December 26, 2007 (Mw = 5.6). Therefore, these earthquakes are crucial to analyze the shallow crustal deformation in the central Anatolian block. In the present study, we obtained source parameters of 2005-2008 earthquake sequence using the regional moment tensor (RMT) inversion method. We analyzed complete broad-band waveforms recorded at near-field distances (0.45° ≤ Δ ≤ 3.6°). Our results reveal NW-SE directed right-lateral strike-slip faulting and NE-SW directed left-lateral strike-slip faulting mechanisms, which are clearly correlated with the conjugate fault systems in the Balâ-Afşar-Sırapınar region. However, some earthquakes also have E-W directed normal faulting components. We suggest that the major characteristics of 2005-2006 and 2007-2008 earthquake activity could have been dominantly associated with left-lateral and right-lateral strike-slip faulting mechanisms, respectively. The seismogenic depth is found to be about 8-10 km. This result implies that earthquakes in the study region occurred mostly in the upper crust, which

    The study of high-redshift bright quasars is crucial to gather information about the history of galaxy assembly and evolution. Variability analyses can provide useful data on the physics of the quasar processes and their relation with the host galaxy. In this study, we aim at measuring the black hole mass of the bright lensed BAL QSO APM 08279+5255 at $z=3.911$ through reverberation mapping, and at updating and extending the monitoring of its C IV absorption line variability. Thanks to 138 R-band photometric data and 30 spectra available over 16 years of observations, we perform the first reverberation mapping of the Si IV and C IV emission lines for a high-luminosity quasar at high redshift. We also cross-correlate the C IV absorption equivalent width variations with the continuum light curve, in order to estimate the recombination time lags of the various absorbers and infer the physical conditions of the ionised gas. We find a reverberation-mapping time lag of $\\sim 900$ rest-frame days for both Si IV and ...

El graffiti emerge en esta ciudad desde la década de los noventa del siglo pasado, como una producción cultural, en torno a la cual las y los jóvenes construyen identidades individuales y colectivas; representan sus realidades, se (reapropian de los espacios públicos, cuestionan el ordenamiento socio-espacial y generan disputas por la definición del paisaje urbano. Con base en estos resultados concluyo que el graffiti es un producto cultural complejo a través del cual las y los jóvenes se posicionan como sujetos políticoculturales.

    Full Text Available Since Eugenio María de Hostos’ publication in 1863 of La peregrinación de Bayoán until 1892, Columbus occupies a central space in his writings. The transformation of Columbus from a Romantic to a Positivist hero serves to exhibit the ideological, historical and political tensions of a colonial Puerto Rican subject questioning his historical and political legacy. It also triggers the examination not only of the figure of Columbus, Spain and the conquest, but of the Nineteenth century complex reality of the American, Caribbean and Latin American nation states.Desde la publicación de La peregrinación de Bayoán (1863 hasta el 1892 la escritura de Eugenio María de Hostos evidencia un especial interés por la figura de Cristóbal Colón. La centralidad del Descubridor, así como su transformación de genio romántico a positivista en el discurso hostosiano pone de relieve las tensiones históricas, políticas e ideológicas de un sujeto puertorriqueño colonial con respecto a su legado histórico-político. Sirve para cuestionar no solo la figura del mismo Colón, sino la conquista, y la situación de los pueblos de las dos Américas en el siglo diecinueve.

    We show for the first time that FBQS J1151+3822 is an iron low-ionization broad absorption line quasar (FeLoBAL QSO), the second-brightest and second-closest known example of this class. He I* and Fe II together act as an effective analytical tool, allowing us to obtain useful kinematic constraints from photoionization models of the outflow without needing to assume any particular acceleration model. The main outflow's log ionization parameter is -1.5, the log hydrogen density [cm^(-3)] 5.5 to 8, the log hydrogen column density [cm^(-2)] 21.7 to 21.9, the absorption radius 7.2 to 127 pc, and the kinetic luminosity 0.16 to 4.5% of the bolometric luminosity. We obtain line-of-sight covering fractions of ~0.25 for strong Fe II, ~0.5 for He I*, and ~0.6 for Mg II. Narrower and shallower absorption lines from weaker Fe II and Mn II with outflow velocity ~3400 km/s have appeared between 2005 and 2011, suggesting that dense cores may have condensed inside the main outflow. Consideration of the literature might sugge...

    We report the results of a new 60 ks Chandra X-ray Observatory Advanced CCD Imaging Spectrometer S-array (ACIS-S) observation of the reddened, radio-selected, highly polarized `FeLoBAL' quasar FIRST J1556+3517. We investigated a number of models of varied sophistication to fit the 531-photon spectrum. These models ranged from simple power laws to power laws absorbed by hydrogen gas in differing ionization states and degrees of partial covering. Preferred fits indicate that the intrinsic X-ray flux is consistent with that expected for quasars of similarly high luminosity, i.e., an intrinsic, dereddened and unabsorbed optical to X-ray spectral index of -1.7. We cannot tightly constrain the intrinsic X-ray power-law slope, but find indications that it is flat (photon index Gamma = 1.7 or flatter at a >99% confidence for a neutral hydrogen absorber model). Absorption is present, with a column density a few times 10^23 cm^-2, with both partially ionized models and partially covering neutral hydrogen models providi...

    Full Text Available El objetivo de este estudio consistió en examinar el efecto de la localización del partido, el nivel del oponente y el marcador sobre las estrategias de posesión del balón en un equipo de fútbol profesional. Para ello fueron analizados 27 partidos de la temporada 2005-2006 de la Liga Española de Fútbol utilizando un sistema computerizado de análisis del juego. Los partidos fueron divididos en episodios de juego de acuerdo con la evolución del marcador. Los resultados del análisis de regresión lineal muestran que la posesión del balón en global y el porcentaje de minutos que el equipo observado tuvo la posesión del balón en cada zona del campo de juego (zona defensiva 1/3, zona media 1/3 y zona ofensiva 1/3 estuvieron condicionados por las variables de situación analizadas, bien de forma independiente o de forma interactiva. La combinación de estas variables y sus interacciones puede ser utilizada para construir modelos que estimen la posesión del balón en el fútbol. Los hallazgos ponen en evidencia la necesidad para los entrenadores e investigadores de tener en cuenta los potenciales efectos independientes e interactivos de la localización del partido, el nivel del oponente y el marcador durante la evaluación del rendimiento de los equipos y los jugadores.

In the method, the composite material was taken as B matrix into which Al fibers were embedded in different configurations. The laminated B-Al material in the form of rectangular plates was subjected to lateral compressive loading. It is observed that stiffeners have significant effect on the buckling behavior of plates under compressive loading and for various geometrical configurations. The stiffeners used in the modeling are one-sided and have rectangular cross-sections. It is found that there are physically important loading intervals and the critical buckling modes make transitions back and forth between stable and unstable states. Bifurcation buckling regions resulting from various configurations of fiber orientations and different plate aspect ratios are determined. The whole analysis is performed by using ANSYS finite element computations. Only the buckling patterns of stiffened

    Full Text Available Hyperresponsiveness of the airways to nonspecific stimuli is a characteristic feature of asthma. Airway responsiveness is usually characterized in terms of the position and shape of the dose–response curve to methacholine (MDR. In the study we have investigated the influence of fluticasone propionate (FP, a topically active glucocorticoid, on arachidonic acid (AA metabolites in broncho-alveolar lavage (BAL fluid (i.e. TxB2, PGE2, PGD2, 6kPGF1α and LTC4 on the one hand and MDR curves on the other hand. The effect of FP was studied in a randomized, double-blind, placebo-controlled design in 33 stable nonsmoking asthmatics; 16 patients received FP (500 μg b.i.d. whereas 17 patients were treated with placebo. We found that the forced expiratory volume in 1s (FEV1 % predicted increased, the log2PC20 methacholine increased and the plateau value (% fall in FEV1 decreased after a 12 week treatment period. No changes in AA-metabolites could be determined after treatment except for PGD2 which decreased nearly significantly (p = 0.058 within the FP treated group, whereas the change of PGD2 differed significantly (p = 0.05 in the FP treated group from placebo. The levels of the other AA metabolites (i.e. TxB2, PGE2, 6kPGF1α and LTC4 remained unchanged after treatment and were not significantly different from the placebo group. Our results support the hypothesis that although FP strongly influences the position, the shape and also the maximum response plateau of the MDR curve, this effect is not mainly achieved by influence on the level of AA metabolites. Other pro-inflammatory factors may be of more importance for the shape of the MDR curve. It is suggested that these pro-inflammatory factors are downregulated by FP.

    Full Text Available The Tumanpınarı mineralization is a volcanic rock-hosted epithermal Fe-Mn-Ba deposit located in the southwestern part of Dursunbey, Balıkesir, Turkey. The deposit constitutes one of the most important deposits of the Havran-Dursunbey metallogenic sub-province in which numerous Early Miocene Fe-Mn-Ba deposits are distributed. The ore occurs as open-space fillings in faults, fractures, and breccias in the andesite. Early hydrothermal activity was responsible for four types of hypogene alteration in decreasing intensity: silicification, sericitization, hematization and argillic alteration. The mineral assemblage includes pyrolusite, psilomelane, hematite, and barite as well as minor magnetite, manganite, poliannite, limonite, braunite, bixbyite, galena, pyrite, and goethite. Mineralogically, three ore types are recognized as pyrolusite + psilomelane + hematite + barite ore, pyrolusite + psilomelane + poliannite ore and barite + pyrolusite + psilomelane + hematite ore (barite-dominant ore. In addition to Fe, Mn and Ba, the ore contains substantial quantities of Pb, Zn, As. Chemically, the transition from fresh to altered rocks has little effect on the elemental levels for Si, Al, Fe, Ca, Mg, K, Rb, Sr and H2O. The homogenization temperature of fluid inclusions hosted in the main stage quartz and barite ranged from 113 to 410 °C with salinities ranging from 0.4 to 14.9 eq. wt % NaCl, respectively. Overall, the available data suggest that the deposits formed as the result of the interaction of two aqueous fluids: a higher-salinity fluid (probably magmatic and a dilute meteoric fluid.

    Precision glass molding (PGM) is an optical manufacturing process used to hot press optical glass into a specified lens shape. This is done by taking the glass to a temperature above Tg and exerting force using an upper and lower mold. These molds will, together, give the pressed lens its shape. This study focuses on the high temperature interactions between the mold tooling material and two optical oxide glasses, Ohara's L-BAL35 and Schott's N-FK5. Flat molds were used to press flat glass work pieces at high temperature and force; key post process parameters such as sample and mold surface contamination using EDS and visible degradation via SEM were catalogued and analyzed. The molds used were bare tungsten carbide (WC) and silicon carbide (SiC) with an amorphous SiC chemical vapor deposition (CVD) coating. The results showed that raw WC molds suffered the most degradation including physical damage as well as chemical adherence and reaction. The Ti binder used in the WC as well as some the tungsten itself transferred to both glasses and caused a white reflective layer to appear on the molded glass surface. Severe damage was evident after only 2 pressing cycles with potassium from N-FK5 being the most prominent chemical contaminant. N-FK5 proved to be the more corrosive of the two glasses in all occasions. The SiC coated molds fared better in terms of degradation than the WC, however sticking of glass to mold was a problem.

    Introduced rodents are responsible for ecosystem changes in islands around the world. In the Galapagos archipelago, their effects on the native flora and fauna are adverse, including the extinction of endemic rodents in some islands and the reduction in the reproductive success of the Galapagos petrel (Pterodroma phaeopygia) in its nesting zones. Understanding the feeding behavior of introduced rodents and their trophic interactions with native and non-native species on islands, can assist in the design of management strategies and conservation plans of invasive and endemic species respectively. Four petrel nesting colonies were monitored during June 2013 on San Cristóbal Island (El Plátano, El Junco, San Joaquín, and La Comuna). The feeding habits of black rats were evaluated by analyzing stomach contents and stable isotopes in hair. Three species of introduced rodents were captured. R. rattus was the most abundant at all sites (n=43, capture success (CS) = 55.8%), followed by the house mouse, Mus musculus (n = 17, CS = 37.8%), and the Norwegian rat, R. norvegicus (n = 4, CS = 4.5%), captured only at La Comuna. The omnivorous black rat ate mostly plants (98%) and arthropods (2%). Intact seeds of Miconia robinsoniana were the main food at all sites (relative abundance=72.1%, present in 95% of the analyzed stomachs), showing the black rats' possible role in the archipelago as endemic seed dispersers. There was no evidence of petrel's intake; however, its possible consumption is not discarded at all. The δ15N and δ13C analysis corroborated the primarily herbivorous diet of black rats. The isotopic signatures of the three rodent species reflect the inter- and intra-specific differential use of food resources. Black rat showed a wider diet in La Comuna, which was related to a lower availability of its primary prey and its ability to adapt to the available resources in its habitat.

    Full Text Available The project of discovering America by Christopher Columbus is an enterprise of Modernity, understood as the modern mentality displayed in the capitalist system. Even though Columbus lived during the Renaissance period, the mentality carried in his project is closer to some modern philosophers such as Descartes and Hobbes, who from rationality and individualism constitute a change of time. The hypothesis that Columbus is a modern person is sustained with evidence in the reasons he explained to defend his project from the Spanish court and especially the final agreement, "the capitulation", in which rationality and individualism took precedence over divine or medieval considerations. The rationalist mentality of Columbus prefigures that from modern businessman who does not stitch without thimble.El descubrimiento de América, impulsado por Cristóbal Colón, es una empresa  de la Modernidad, entendida esta como la mentalidad moderna desplegada en el sistema capitalista. Si bien es cierto que Colón, por la época en que vivió, se ubica  dentro del Renacimiento, la mentalidad con que fue llevada a cabo su iniciativa está más cerca de modernos como Descartes y Hobbes, quienes, a partir de la racionalidad y el individualismo, configuran un cambio de época. La hipótesis de que Colón es un moderno se sustenta con muchas evidencias en las razones que construyó para defender su proyecto ante la corte española y especialmente en el acuerdo final, “la capitulación”, en donde la racionalidad y el individualismo priman sobre consideraciones divinas o medievales. La mentalidad racionalista de Colón prefigura la del empresario moderno que no da puntada sin dedal.

    In this study, the populations and abnormal shell structures of Quaternary foraminifers in the sediments of the North-eastern Aegean Sea were examined. For this purpose, offshore drilling was carried out at three locations, and core samples were collected from 13 locations at Küçükkuyu (Çanakkale), Güre (Edremit-Balıkesir) and Dikili (İzmir). At these points, drilling reached depths ranging from 3.00 to 22.00 m beneath the seafloor; recent sediments were observed, but the bedrock was not reached. Examination of the faunal and sedimentological properties of the samples showed that the Gulf of Edremit is completely influenced by the sea and has rich foraminifers and ostracod populations. The abnormalities observed in the foraminifer shells, as well as the yellow- and/or black-coloured shells seen in both the foraminifer and ostracod populations, are due to natural and anthropogenic ecological pollution. The vertical (chronological) and horizontal (spatial) distributions of heavy metal concentrations in both the core and drill core samples were investigated to determine the causes of the morphological abnormalities observed in the foraminifers. In the present study, pollution index (PI) values were calculated to assess the degree of heavy metal pollution (Yümün 2017). The current land use status of the coastal areas corresponding to the measured PI values was investigated to identify the sources of the pollution. Especially in the Güre region, a large number of genera and species of benthic foraminifers showed overgrowth in the shell sizes of individuals, and the coloration of the shells is noteworthy. These changes in the shells are a result of thermal sources and agricultural activities in the region. Scanning electron microscopy (SEM) was used to perform an elemental analysis of the surfaces of dark yellow-orange foraminifers (Ammonia compacta and Elphidium crispum). The S, Fe and Mn concentrations in the shells were found to be high, based on the SEM

  12. La obra de Aníbal Núñez en el contexto de la poética posmoderna española (Notas para una restitución generacional

    Vives Pérez, Vicente

    2008-12-01

    Full Text Available After decades of seclusion in the shadow of its promotion, Aníbal Núñez’s poetry is starting a recovery process in recent critical studies. After overcoming the restrictive premises used by poetry criticism to reduce the authors´ list and poetical tendencies of 68, the isolation of those poets —whose works did not fit in the dominant canon— is object of review in current historiography of Spanish contemporary poetry. This return to the once-excluded poets is essential to understand the plurality of discourses which make up the generation of 68: it is necessary to revive their voices of discord in order to outline their whole aesthetic scene. In the light of the innovative theoretic-critical paradigm of Spanish postmodern poetry, the works by Aníbal Núñez may be fully part of the creative scene of his generation, without forgetting the peculiarities which distinguish his poetic writing.Tras décadas de reclusión en la zona umbrosa de su promoción, la poesía de Aníbal Núñez está iniciando un proceso de recuperación en los estudios críticos recientes. Superadas ya las restrictivas premisas con que la crítica redujo la nómina de autores y tendencias poéticas del 68, el aislamiento de los poetas cuya obra no encajaba en el canon hegemónico es objeto de revisión en la actual historiografía de la poesía española contemporánea. Esta restitución de los excluidos es esencial para entender la pluralidad de los discursos que componen la generación del 68: recuperar sus voces discordantes es necesario para trazar su escenario estético completo. A la luz del innovador paradigma teórico-crítico de la poética posmoderna española, los libros de Aníbal Núñez pueden insertarse plenamente en el panorama creador de su generación, sin menoscabo de las peculiaridades que singularizan su escritura poética.

    Full Text Available Os materiais compósitos de matriz polimérica (PMCs reforçados por fibras são considerados excelentes materiais de engenharia. Em aplicações estruturais, quando uma elevada relação resistência peso é fundamental para o projeto, os PMCs vêm substituindo com sucesso diversos materiais convencionais. Materiais têxteis são utilizados, desde a 2ª Guerra Mundial, como blindagens balísticas. Materiais fabricados com fibra do polietileno de altíssimo peso molecular (UHMWPE são empregados na produção de blindagens, para proteção pessoal e em carros de combate. Todavia, em virtude de terem sido desenvolvidos e comercializados mais recentemente, não existem informações suficientes sobre o desempenho balístico desses materiais após a sua exposição aos agentes ambientais. No presente trabalho foi estudado o comportamento balístico de placas compósitas fabricadas com fibra de polietileno de altíssimo peso molecular (UHMWPE, após sua exposição à radiação gama. Os resultados dos testes balísticos foram relacionados com as alterações macromoleculares induzidas pela irradiação por meio de ensaios mecânicos (dureza, impacto e flexão e físico-químicos (espectroscopia no infravermelho, calorimetria diferencial de varredura e análise termogravimétrica. Foi verificado que a irradiação gama provoca modificações nas cadeias macromoleculares do polímero, que alteram as propriedades mecânicas do compósito de UHMWPE, reduzindo, nas doses de radiação mais elevadas, o seu desempenho balístico.

Entre sus autores se hallan Rodolfo Lenz, Miguel Luis Amunátegui Reyes y Fidelis del Solar, quienes desempeñaron papeles importantes en el desarrollo de la lingüística en Chile. Concluimos que la recepción de la obra de Echeverría fue mayormente negativa porque los comentaristas la interpretaron como una obra prescriptiva que adolecía de defectos fundamentales para cumplir con su propósito normativo, interpretación congruente con el periodo de la lexicografía y la lingüística chilena en que se enmarca, llamado precientífico por Matus (1994 y caracterizado por un marcado interés normativista. Entre las críticas más abundantes sobresale el desacuerdo sobre el tratamiento normativo dado a ítems particulares, lo cual interpretamos en términos de una negociación de normas connatural a una comunidad lingüística que atraviesa un proceso de estandarización, como era el Chile hispanohablante de fines del siglo xrx.This paper analyzes how Voces usadas en Chile, a lexicographical work written by Chilean lawyer and amateur linguist Aníbal Echeverría y Reyes and published in 1900, was received by his contemporaries, as it can be seen in a corpus of six critical texts dated between 1899 and 1905.

    Full Text Available Inhabitants of urban and rural areas are important participants in the process of developing and implementing forest policy. Thus, it is essential to determine their demands and attitudes towards forestry issues. In this context, the demands and evaluation of forest functions are investigated in a case study of the Turkish province of Bal kesir. The findings of the case study show that differences in terms of demands among inhabitants of rural and urban areas are related to forest fires fighting, crimes fighting, forestry-tourism integration, forestation and regeneration activities, and the enlargement of forest areas. The main differences among their assessments of forest functions are related to fire wood production, and the provision of flood and erosion control, nature protection, and recreational opportunities. The findings are important for conflict management and for local decision making. By using the findings of similar studies, the provincial organizations should harmonize their priorities with the expectations of relevant interest groups.A política de silvicultura da população urbana e rural é uma participante fundamental no processo de formação e execução das florestas.

    Full Text Available The San Cristóbal pluton is a 35 km2 granitic body that outcrops at the southestern tip of the Sierra de Velasco, located west of La Rioja city, Argentina. It is formed by monzogranites and syenogranites, together with scarce granodiorites, with medium to fine-grained, equigranular to slightly porphyritic textures. Their mineral assemblage consists of quartz + microcline + plagioclase + biotite ± muscovite + zircon + apatite + magnetite. The granite contains dioritic to tonalitic mafic enclaves. The central and eastern parts of the granite have been deformed by the NNW-SSE trending South Mylonitic shear zone formed by mylonitic rocks. The metamorphic host-rock is represented by scarce greenschist facies xenoliths and hornfels with the high T / P assemblage K-feldspar - cordierite - biotite ± sillimanite. The granites are calc-alkaline, weak- to moderately peraluminous, and formed as part of a continental magmatic arc developed along the active margin of western Gondwana during the Early Paleozoic. The depth of emplacement of the San Cristóbal pluton is estimated at ~12 km.

    The lattice parameters, band structure, density of states, effective mass, carrier concentration and electrical resistivity of 3C-SiC in different doped forms (undoped, B-doped, Al-doped and B-Al co-doped) are calculated using the plane wave ultrasoft pseudopotential based on density functional theory. Calculations indicate that as the B or Al replaces Si atoms, both the conduction band and valence band shift to higher energy level. The top of valence band shifts quicker, resulting in the decrease of the band gap. B-Al co-doped 3C-SiC shows the narrowest bandgap while the pure one has the widest. Effective mass of B-doped 3C-SiC decreases but that of Al-doped 3C-SiC increases;while B-Al co-doped 3C-SiC effective mass, whose value approaches to the undoped, can be understood in terms of different compensation. As the acceptor impurities, B and Al will greatly increase the carrier density of valence band top, and the carrier density of the co-doped is three times as Large as the B-doped or Al-doped 3C-SiC. In addition, B-Al co-doping has the lowest resistivity among the four doping forms displaying its significant advantages in electrical property.%采用基于密度泛函理论的第一性原理平面波超软赝势法,计算了未掺杂, B, Al单掺杂和B-Al共掺杂的3C-SiC的晶格参数、能带结构、态密度、有效质量、载流子浓度和电阻率.计算结果表明:掺杂后导带和价带都向高能端移动,价带移动速度更快一些,使得禁带宽度都有一定程度的减小,其中B-Al共掺杂的禁带宽度最窄,纯净3C-SiC的禁带宽度最宽;B掺杂会减小价带顶空穴的有效质量, Al掺杂则反之, B-Al共掺杂补偿了二者的差异,和未掺杂的3C-SiC价带顶空穴的有效质量很接近. B和Al作为受主杂质,会极大地提高价带顶空穴载流子的浓度,而且B-Al共掺杂的3C-SiC的价带空穴浓度是B, Al单掺杂时的3倍.4种体系中, B-Al共掺杂得到的电阻率是最低的,同单掺杂

    Full Text Available Although the image of America in the Spanish literature of the Golden Age has not been analyzed very often by the hispanists, it is remarkable that the character of the indiano —the Spaniard that emigrated to the Indias— is condemned by a prose writer from Valladolid, Dr. Cristóbal Suárez de Figueroa, in his fictional work El pasajero, dated in 1617. In that narrative, Suárez strongly disapproves colonization and, without openly defending aborigines, attacks the indianos on the grounds of their greed, ignorance, and double-dealing. In this study, Suárez’s denounce is compared to other contemporaries’ more moderate views.

    Aunque la imagen de América en la literatura española del Siglo de Oro no ha sido todavía analizada con demasiado detenimiento por los hispanistas, hay que destacar que el personaje del indiano —el emigrante español en las Indias Occidentales— es condenado por un escritor en prosa de Valladolid, el doctor Cristóbal Suárez de Figueroa, en su obra de ficción El pasajero, de 1617. En ese relato, Suárez desaprueba la colonización y, sin defender abiertamente a los indígenas, ataca a los indianos por su codicia, ignorancia y doblez. En este estudio, la denuncia de ese autor es contrastada con otras visiones de sus contemporáneos, en general más matizadas.

Adicionalmente, se examina la situación de las empresas familiares en México y su relevancia e importancia para la economía. Se encontró que la importancia de la empresa familiar, tanto a nivel nacional como local, y el amplio desarrollo de la actividad restaurantera en San Cristóbal de las Casas, motivan a las familias dedicadas a esta actividad a continuar sus negocios y a transmitirlos a las futuras generaciones para ser sustentables, ya que, de acuerdo con lo que reporta el Instituto Nacional de Estadística y Geografía (INEGI, nueve de diez empresas familiares que se crean no llegan a los dos años de vida, lo cual constituye un índice de mortalidad extremo.         La unión familiar al interior de la empresa es el vínculo ideal para la sustentabilidad de la misma, ya que de ella depende una exitosa sucesión generacional que propicie que la empresa familiar perdure en sus actividades.

    The objects of the empirical science known as particle physics are not like objects ordinarily conceived. Physicists' particles can enter states strangely entangled with those of other particles; they can obey statistics which suggest that they lack genidentity; their properties (some think) are created in measurement, or (others think) can only be limned from the symmetries of the theory describing them. 'The implications of contemporary physical theories for the debate on the nature of objects' provides 'the central theme' (p. 4) of Interpreting Bodies, editor Elena Castellani's new collection of essays. Contributions to the volume vary dramatically in vintage (Born's and Reichenbach's are well into middle age; others appear here for the first time); in approach (the collection includes Giuliano Toraldo diFrancia's nine-page history of the object concept from Democritus to d'Espagnat, Peter Mittelstaedt's discussion of the Kantian constitution of quantum objects, and Giulo Peruzzi's explication of the scattering cross section and its role in experimental particle physics); and in intended audience. Lacking the space to treat each contribution in turn, I will focus on those dealing with the problem of the One and the Many.

    Full Text Available Ya Joseph Pérez en su clásica obra sobre la Guerra de las Comunidades, en 1970, propugnaba la necesidad de investigar las consecuencias de la revuelta y, en particular, las indemnizaciones a los leales al Emperador que se exigieron tras el fin de la guerra. De esto tratan estas páginas. Concretamente de los procesos que se desencadenaron en la ciudad de Jaén para resarcir a dos de los principales acosados por los comuneros: Cristóbal de Biedma, procurador a las Cortes de La Coruña, y el letrado Juan de Santoyo. El artículo no solo analiza una documentación totalmente inédita y que se encuentra en el Archivo de la Real Chancillería de Granada, sino que da a conocer igualmente fuentes que versan sobre una de las zonas, como es la andaluza, más desconocidas por lo que respecta a este importante suceso de la Historia Moderna de la Monarquía española.As early as 1970, Joseph Pérez, in his classical work on Guerra de las Comunidades, suggested the need to do research into the consequences of the revolt, focusing on the compensations that were demanded by those who remained loyal to the Emperor This paper approaches the issue, placing special emphasis on the litigations that were triggered in the city of Jaén to compénsate two of the principal personages who were harassed by the commoners: Cristóbal de Biedma, provincial councillor for La Coruña, and the lawyer Juan de Santoyo. This article analyses documentary sources from the Archive of the Real Chancillería de Granada that were never published previously in any form. Furtliermore, it brings to light historical and documentary sources pertaining to the little known role of Andalusia during this important event in the early modern history of the Spanish monarchy.

    Full Text Available Las estenosis esofágicas son situaciones relativamente frecuentes en la práctica médica diaria. Se dividen en malignas y benignas de acuerdo con significación, pronóstico y conducta ante ellas. Mientras que en el primer grupo predominan las neoplasias primarias de esófago, el segundo representa un grupo de causas múltiples y heterogéneas. El presente trabajo trata sobre el desarrollo de una estenosis esofágica benigna, de tipo isquémico, a partir del uso de sonda de balón (sonda de Blakemore-Sengstaken para tratar un episodio de sangrado digestivo alto. Debido a lo infrecuente de esta complicación, así como a la escasez de datos científicos o investigativos sobre el tema, se discuten los posibles mecanismos fisiopatológicos involucrados, así como las principales estrategias terapéuticas, tanto profilácticas como curativas, necesarias para la atención de estos pacientes

La evaluación geomorfológica del sector montañoso contiguo a la zona sismogénica más cercana mostró evidencias sobre el carácter activo de la falla Pinar, mediante la aplicación de los indicadores de disección vertical del relieve, incisión fluvial, separación de cuencas y profundidad y sinuosidad del frente montañoso. Los resultados permitieron clasificar los suelos en tres tipos, según su respuesta sísmica, y realizar un pronóstico de la variación de la intensidad macrosísmica, en función de las características geotécnicas locales, lo cual constituye una herramienta de trabajo para futuros planes de ordenamiento urbano.

    Full Text Available Los parámetros geotécnicos de los suelos (número de golpes del ensayo de penetración estándar, densidad natural, contenido de finos, límite líquido, humedad y el índice de plasticidad intervienen en las ecuaciones empíricas para determinar la variación de la intensidad sísmica, la velocidad de ondas transversales, la susceptibilidad a la licuefacción, entre otros. Generalmente, se emplean valores promedios que caracterizan la formación geológica, o un complejo ingeniero geológico, lo que induce una gran incertidumbre. Este artículo propone un procedimiento para la estimación y modelación de los principales parámetros geotécnicos que inciden en la zonación sísmica local. El procedimiento consta de cuatro etapas: la elaboración de bases de datos, el análisis exploratorio de datos, la creación del modelo geológico 3D y, finalmente, la generación del modelo cuantitativo. La aplicación de esta metodología en la ciudad de San Cristóbal reveló valores bajos de densidad natural, lo que sugiere condiciones desfavorables de respuestas de los suelos frente a sismos

Este mecanismo acrecional sería similar al observado en otros núcleos cratónicos arqueanos-paleoproterozoicos, tales como los de Amazonas, Kalahari y Congo. Finalmente, la otra fuente importante de aporte de los Esquistos Santa Helena indica la existencia de una faja de rocas magmáticas neoproterozoicas que correspondería a un arco desarrollado sobre el margen oriental de Pampia.The Santa Helena Schists comprise biotite-garnet schists and minor sillimanite-garnet gneissoid lenses, reaching the higher amphibolite to lower granulite facies metamorphism . Suboutcrops of the schists occur at Estancia Santa Helena. U-Pb SHRIMP dating of the Santa Elena Schists detrital zircon yielded mostly Mesoproterozoic and Neoproterozoic ages, with a small number of Paleoproterozoic grains. Almost all the Mesoproterozoic and Neoproterozoic grains are magmatic and crystallized from a juvenile source (positive εHf, with TDM (Hf ranging 1127 to 1625 Ma, and 948 to 1274 Ma, respectively. The Paleoproterozoic zircons are also magmatic, with a TDM (Hf of 2310 Ma. The age of the youngest detrital zircon is 556 Ma, which corresponds to the maximum age for the onset of sedimentation, indicating that deposition probably started by Neoproterozoic times. The absolute absence of metamorphic zircons of Pampean age suggests that during the time of deposition of the schists, the metamorphic nucleous of the Pampean orogen was still not formed and exposed. This implies a great contrast with the provenance pattern of the nearby Green Schists, dominated by Cambrian metamorphic zircons, deposited between ca. 500 Ma and ca. 465 Ma, when the Pampean orogen was already exhumed and subject to denudation.

  19. Black coffee. Marcel Duchamp’s pataphysical sensism

    Directory of Open Access Journals (Sweden)

    Dirk van Weelden

    2016-06-01

    Full Text Available Duchamp’s readymade is usually interpreted as a bold and cerebral emancipation of modern art from the material, the craft and natural beauty, and the discovery of the continent of conceptual art. Duchamp however was very sceptical and made fun of abstract reasoning, concepts and theories. This essay states that Duchamp ostensibly found inspiration with Alfred Jarry’s work and particularly his ‘neo--science’ of pataphysics, like many dadaïsts, futurists, surrealist did around 1910. And that he did so openly. Beyond art and the possibility of conceptual art lies the pataphysical, the vast and rich realm of the senses. Duchamp’s interest was not in concepts or ideas, his drive was towards the virtual, ambiguous, irrational side of perception. All we have is the senses, the unique moments, the unique objects and bodies, our memories, and what the chaotic abundance of information they give us means, is unknown. Probably nothing. Duchamp thought that all science, art, religion, madness, literature and philosophy are creative efforts starting from tautologies; he was no conceptualist but a radical ‘sensist’.

OBJECTIVE: To describe the effectiveness of a quality of care protocol in reducing the door-to-balloon time. METHODS: Between May 2010 and August 2012, all individuals undergoing primary angioplasty in our hospital were analyzed. The door time was electronically recorded at the moment the patient took a number to be evaluated in the emergency room, which occurred prior to filling the check-in forms and to the triage. The balloon time was defined as the beginning of artery opening (introduction of the first device. The first 5 months of monitoring corresponded to the period of pre-implementation of the protocol. The protocol comprised the definition of a flowchart of actions from patient arrival at the hospital, the team's awareness raising in relation to the prioritization of time, and provision of a periodic feedback on the results and possible inadequacies. RESULTS: A total of 50 individuals were assessed. They were divided into five groups of 10 sequential patients (one group pre- and four groups post-protocol. The door-to-balloon time regarding the 10 cases recorded before protocol implementation was 200 ± 77 minutes. After protocol implementation, there was a progressive reduction of the door-to-balloon time to 142±78 minutes in the first 10 patients, then to 150±50 minutes, 131±37 minutes and, finally, 116±29 minutes in the three sequential groups of 10 patients, respectively. Linear regression between sequential patients and the door-to-balloon time (r = - 0.41 showed a regression coefficient of - 1.74 minutes. CONCLUSION: The protocol implementation proved effective in the reduction of the door-to-balloon time.

    Full Text Available Resumen El objetivo de este estudio es conocer cuáles son las mejores condiciones de aprendizaje del lanzamiento a canasta en baloncesto en la etapa pre-infantil. En esta etapa existe un cambio brusco para el niño en función del tamaño del equipamiento, que exige realizar un proceso de adaptación progresivo de las dimensiones del balón y de la canasta, permitiendo que los jugadores tengan un aprendizaje más adecuado y adaptado a sus características. La muestra estuvo formada por 12 jugadoras pre-infantiles (11-12 años, pertenecientes a un equipo de baloncesto femenino. Se analizó la eficacia de los lanzamientos a canasta en función del tamaño del balón y la altura de la canasta, así como de la posición del lanzamiento, antes y después de un proceso de intervención. Los resultados mostraron que al inicio del proceso existían diferencias en la eficacia de los lanzamientos. Las jugadoras eran más eficaces lanzando con balón minibasket (numero 5 y canasta de minibasket que con los del juego adulto (numero 6. Finalmente, tras el proceso de intervención los resultados mostraron como las jugadoras aumentan su eficacia cuando lanzan con balón y canasta grande con respecto al inicio de la temporada. Además, en el pos-test obtuvieron mayores valores de eficacia con este material que con el balón y la canasta pequeña.

    The Miocene volcanic rocks along the İzmir-Balıkesir Transfer Zone along the western margin of the Menderes Core Complex (MCC) in western Anatolian Volcanic Province (WAVP), where strike-slip deformation is dominant, comprise: (Group 1) early-middle Miocene high-K to shoshonitic rocks with high-Mg# and relatively low SiO2, (Group 2) middle Miocene phonolitic rocks with low-Mg# and intermediate SiO2, (Group 3) early-middle Miocene medium- to high-K series from andesites to rhyolites, (Group 4) middle Miocene rhyolites with distinct trace element compositions; and (Group 5) late Miocene high-MgO basalts, K-trachybasalts and (Group 6) late Miocene high-MgO basaltic andesites. The geochemical features of these rocks are comparable with the other Oligocene to Miocene volcanic rocks, but differ from the Eocene volcanic rocks in WAVP. The geochemical features of the most primitive early-middle Miocene Group 1 rocks indicate that they were derived from an anomalously metasomatized lithospheric mantle. The mineralogical and geochemical properties of garnet-amphibole peridotite from the Ulten Zone (UZP), Eastern Alps, which is thought to represent a fossil metasomatic mantle wedge contaminated by continental subduction, is similar to the model mantle composition previously proposed for the genesis of the mafic rocks. Together with the presence of Eocene to early Miocene continental subduction beneath the Aegean-west Anatolia region, this strongly suggests that continental subduction was an important factor in the genesis of the high-MgO shoshonitic to ultrapotassic volcanism in this post-collisional area. The origin of the Group 3 andesitic to rhyolitic rocks includes; (1) lower crustal melting, (2) mixing between lower crustally-derived and mantle-derived melts, and (3) FC-AFC processes. The late Miocene Group 5 and 6 rocks, however, derived from a more depleted mantle source, indicating that the mantle became depleted over time. The rhyolites of Group 4 are most probably

    Full Text Available The book "Überlebenskunst in Übergangswelten" [The Art of Surviving in Transitional Worlds] is the first of two recent publications from the Ethnological-Psychological Centre in Zurich. The branch of the Asylum-Organisation of the Canton Zurich offers people who have fled their home country and who are now suffering from psychological crisis, inpatient or in-house or ambulatory treatment. The refugees physically escaped war, torture and/or imprisonment. However, they are unable to master the difficult process of migration and gradual arrival integration into the new, cultural and social contexts in Switzerland. As a result they have psychological problems, which make it impossible for them to live a "normal" everyday life. In three houses of the Centre, the so-called Foyers, they can find potential help. The migrants meet with a team of five ethno-psychologists, which uses ethnological and psychological approaches in order to understand the newcomers' problems. Within their work, the professionals of the Centre have developed a theoretical and methodological repertoire, which is of model-character not only within Switzerland but also for other countries. David SIGNER focuses in his article on characteristic conflicts and patterns of interaction in everyday life in the Foyers. The author emphasises the need to be open for all sorts of perception and communication. Furthermore, he sheds light on the various "pitfalls" in trying to create interaction. Elena WERTLI's text concentrates on refugees suffering from suicidal crisis. She explicates that a continued dialog is sometimes of more help for people in extreme psychological situations than a fast intervention. Daniel STUTZ' approach towards the problems of a Kurdish family is to first reconstruct the latter's individual life histories. The method enables him to explain the ongoing physical problems and the family's growing fear to get infected by bacteria as an expression of the couple's fear

    Only one-third of patients with depression respond fully to treatment with antidepressant medication. However, there is little robust evidence to guide the management of those whose symptoms are 'treatment resistant'. The CoBalT trial examined the clinical effectiveness and cost-effectiveness of cognitive behavioural therapy (CBT) as an adjunct to usual care (including pharmacotherapy) for primary care patients with treatment-resistant depression (TRD) compared with usual care alone. Pragmatic, multicentre individually randomised controlled trial with follow-up at 3, 6, 9 and 12 months. A subset took part in a qualitative study investigating views and experiences of CBT, reasons for completing/not completing therapy, and usual care for TRD. General practices in Bristol, Exeter and Glasgow, and surrounding areas. Patients aged 18-75 years who had TRD [on antidepressants for ≥ 6 weeks, had adhered to medication, Beck Depression Inventory, 2nd version (BDI-II) score of ≥ 14 and fulfilled the International Classification of Diseases and Related Health Problems, Tenth edition criteria for depression]. Individuals were excluded who (1) had bipolar disorder/psychosis or major alcohol/substance abuse problems; (2) were unable to complete the questionnaires; or (3) were pregnant, as were those currently receiving CBT/other psychotherapy/secondary care for depression, or who had received CBT in the past 3 years. Participants were randomised, using a computer-generated code, to usual care or CBT (12-18 sessions) in addition to usual care. The primary outcome was 'response', defined as ≥ 50% reduction in depressive symptoms (BDI-II score) at 6 months compared with baseline. Secondary outcomes included BDI-II score as a continuous variable, remission of symptoms (BDI-II score of anxiety and antidepressant use at 6 and 12 months. Data on health and social care use, personal costs, and time off work were collected at 6 and 12 months. Costs from these three perspectives were

    Full Text Available ResumenEl rendimiento en acciones explosivas como el golpeo de balón y el salto vertical es de gran relevancia en el fútbol. Los objetivos del presente estudio fueron: 1 Estudiar la secuencia del golpeo en futbolistas jóvenes de alto nivel, y, 2 analizar las posibles relaciones existentes entre el golpeo de balón y el salto vertical. 21 jugadores de alto nivel (16,1 ± 0,2 años llevaron a cabo un test de salto vertical con contramovimiento (CMJ y un test de golpeo de balón con la máxima potencia. Los datos fueron registrados mediante una plataforma de fuerzas (Dinascan IBV y un sistema de captura automática del movimiento (Vicon. Con este estudio, se aporta información sobre la cinemática del golpeo en futbolistas juveniles de alto nivel. En función de los resultados obtenidos, se puede afirmar que la secuencia temporal de máximos de velocidad sucede desde el extremo más proximal al más distal, incrementándose la velocidad. La ausencia de relación entre el golpeo y el salto sugiere el trabajo de fuerza explosiva específico para la mejora de cada una de ellas.AbstractKicking and vertical jumping performance are very important in soccer. The aims of the present study were: 1 To study the kinematical sequence of the soccer kick in young top-class soccer players, and, 2 to analyse the possible relationships among the different parameters related to the soccer kick and the vertical jump in this population. 21 top-class soccer players (16,1 ± 0,2 yr. performed a countermovement jump test (CMJ and a maximum power soccer kick test. Data was obtained from a Dinascan IBV force platform and the Vicon system of automatic capture of the movement.

Methods The clinical manifestation, laboratory examination, neuroimaging characteristics, pathology and follow-up of 12 (2 outpatients and 10 inpatients) cases of BCS were analyzed retrospectively. Results The onset age of 12 patients (male 4, female 8) ranged from 8 to 54 years old (mean 36.8 years). Unconcerned and slowness response were common in the disease onset (7 cases).Other symptoms and signs such as hypophrenia ( 10 cases), limitation of limb or hand movement (8 cases),urinary and fecal incontinence (7 cases), hypo-myodynamia (7 cases), positive pyramidal sign (6 cases)were not rare in course of disease. Eight cases underwent the examination of cerebrospinal fluid myelin basic protein, which increased in 7 cases. Demyelinating change and perivascular inflammatory infiltration were shown in 6 brain biopsies. The involvements of multi-lesions were found in 11 cases. Four patients underwent CT scanning and all the cases showed with hypodense lesions and couldn' t be enhanced. On MRI, all cases appeared round or round-like in shape. Enhanced lesions showed ring-like or half-ting-like shape (8 cases) and concentric ring (3 cases). It's easy to be misdiagnosed as brain tumor (8 cases).Conclusions BCS is a kind of demyelinating disease of subacute or chronic onset accompanied with cognitive disorder being the most common initiating symptoms. It's prone to be misdiagnosed. Diagnosis depends on MRI and corticosteroid treatment is effective. BCS has a good prognosis and presents with benign clinical course.%目的 探讨同心圆硬化的临床表现、影像学特征及其诊断价值.方法 回顾12例同心圆硬化患者(门诊2例,住院10例)的临床表现、实验室检查结果、影像学特点及病理结果,并对患者进行随访.结果 12例患者(男4例,女8例)发病年龄8~54岁(平均36.8岁),多以淡

This place decorated with colorful mosaics and wall paintings also having a good handcrafted floor is dated back to Roman Empire period. Besides Dionysos, Ariadne, Meinad, and Eros holding a wineglass figures related with Dionysos cult on the mosaic; theatre masks, fish and bird figures all together demonstrate that it could be used as a banquet hall for official invitations during theatre plays.  These fish and bird figures have great importance to analyze the nutrition habits of antique cities, especially metropolis, which has few materials that could be read. The various fish and bird figures on the reception hall were examined by expert zoologists to try to identify the factors such as, this fish and birds’ species, their habitats and if they were eatable or not. The paper also tries to find out the nutrition habits of Metropolis community using the found data from ancient sources and obtained from this research.

    Full Text Available O tratamento da síndrome de baixo débito cardíaco tem evoluído muito, em especial em relação aos dispositivos mecânicos de assistência ventricular. Esses dispositivos podem genericamente ser agrupados em pulsáteis e não pulsáteis. Existe grande polêmica sobre as vantagens e desvantagens de cada um desses grupos de dispositivos. O objetivo deste trabalho é avaliar a ação da bomba centrífuga sobre o fluxo coronário e carotídeo na assistência circulatória do ventrículo esquerdo em cães com coração normal. Além disso, verificamos se o uso concomitante do balão intra-aórtico é suficiente para contrabalançar os possíveis efeitos deletérios da assistência circulatória com fluxo contínuo. Foram estudados 15 cães, com peso corpóreo médio de 16,3 kg. Realizamos a avaliação hemodinâmica dos animais, através da medida seriada das pressões do átrio direito, do capilar pulmonar, das artérias pulmonares, da circulação arterial sistêmica e a freqüência cardíaca. Foi realizada a aferição do débito cardíaco e calculados os seguintes parâmetros hemodinâmicos derivados: índice cardíaco, índice sistólico, resistência vascular sistêmica e resistência vascular pulmonar. O fluxo sangüíneo carotídeo e coronariano foram obtidos com o uso de transdutores eletromagnéticos. Os parâmetros foram analisados em quatro situações: S1. situação controle; S2. situação de teste da bomba centrífuga em que esse dispositivo realiza a assistência circulatória do ventrículo esquerdo; S3. situação de teste da bomba centrífuga e do balão intra-aórtico; S4. situação final em que é feita a contraprova desligando-se o balão intra-aórtico. A avaliação hemodinâmica através dos diversos parâmetros não mostrou alteração estatisticamente significante nas quatro situações. Já em relação ao fluxo coronário a utilização da assistência circulatória isolada com bomba centrífuga (S2 e S4 diminuiu

    Full Text Available OBJETIVO: A neoproliferação intimal e o remodelamento têm sido implicados como os maiores fatores causadores de reestenose. O objetivo deste trabalho é estudar a ação da L-arginina por via oral, nesses dois fatores, após lesão por balão, em artérias ilíacas de coelhos hipercolesterolêmicos. MÉTODOS: Foram utilizados dezenove coelhos, que foram divididos em dois grupos: controle (GC e arginina (GA, respectivamente com dezenove e dezessete artérias estudadas. Os animais foram submetidos a lesão por balão de angioplastia, em suas artérias ilíacas, quinze dias após início de dieta hipercolesterolêmica a 2%. A seguir, os animais do GA passaram a receber uma solução de L-arginina, por via oral, na dose de 1 g/kg/dia. Após o sacrifício, no 15º dia após a lesão por balão, procedeu-se a cortes histológicos das artérias, as quais foram coradas e fixadas. Utilizou-se como representativa do desenvolvimento da lesão a razão da área da neoíntima (em mm² pela camada média (em mm². Por sua vez, a razão da área total do vaso em sua porção medial (de maior contato com o balão pela área total do vaso no segmento referencial (de menor contato com o balão foi a definidora do remodelamento. RESULTADOS: A média do espessamento neointimal (NI/M foi de 0,8151±0,2201 no GC e de 0,3296±0,1133 no GA. Não houve diferença entre os tipos de remodelamento entre os dois grupos estudados. CONCLUSÃO: No modelo experimental utilizado, a L-arginina foi capaz de reduzir o espessamento intimal em coelhos hipercolesterolêmicos e não teve ação sobre o remodelamento arterial.OBJECTIVE: It has been implied that neointimal proliferation and remodeling are the major causes of restenosis.

    Full Text Available OBJETIVO: A troca valvar aórtica é procedimento rotineiro, envolve substituição da valva nativa/prótese. Na maioria destes pacientes o risco é aceitável, porém, em alguns casos, o risco predito pode justificar contra-indicação. O implante de valva aórtica minimamente invasivo transcateter e sem circulação extracorpórea (CEC tem se mostrado viável, com menor morbi-mortalidade. O objetivo deste trabalho foi desenvolver bioprótese aórtica, montada em cateter, para implante sem CEC. MÉTODOS: Após desenvolvimento em animais, três pacientes com EuroSCORE elevado foram submetidos ao implante. Caso 1: portador de bioprótese com disfunção; Caso 2: estenose aórtica grave; Caso 3: disfunção de bioprótese aórtica. Após minitoracotomia e sob controle ecocardiográfico e fluoroscópico, cateter-balão foi posicionado sobre posição aórtica e insuflado. Após, segundo cateter-balão, com endoprótese valvada, foi posicionado e liberado sob alta frequência ventricular. Controles angiográficos e ecocardiográficos foram realizados e pacientes encaminhados para UTI. RESULTADOS: No primeiro caso foi possível implante sem CEC com resultados adequados. Evoluiu com melhora da função ventricular. Cursou com broncopneumonia, fístula traqueo-esofágica e óbito por mediastinite. Necropsia confirmou bom posicionamento valvar e preservação dos folhetos. O segundo caso apresentou migração do dispositivo após insuflação do balão, necessidade de esternotomia mediana de urgência, CEC e troca valvar convencional. O paciente evoluiu bem, recebendo alta da UTI 14 dias após procedimento e sem complicações. Cursou com infecção respiratória, choque séptico e óbito no 60º pós-operatório. O terceiro caso foi submetido a implante com sucesso. CONCLUSÃO: O implante de bioprótese transapical montada em cateter sem CEC mostrou ser procedimento factível. Detalhes técnicos e a curva de aprendizado demandam discuss

    ¿Se propuso Proust construir una estética como un sistema? Podría pensarse que sí y que ya está escrita y que es su famosa doctrina estética de El tiempo recobrado, pero en cambio entiendo a esta doctrina como un campo metateórico y metaficcional que es imposible de ser leído sin el resto de la Recherche, de las relecturas posibles de la misma y de los frecuentes análisis sobre el arte del novelista. No se trata de que la doctrina estética contenga afirmaciones falsas sino ficcionales y por l...

    Full Text Available Este artigo analisa a obra clássica de M. Mauss, Ensaio sobre a dádiva, à luz de desenvolvimentos recentes da Antropologia. Salienta como contribuição de Mauss o entendimento da dimensão política da troca de dádivas, assim como a sugestão de sua universalidade, posteriormente demonstrada por Lévi-Strauss, constituir-se em princípio formal-abstrato, e não num fato empírico-concreto. A partir desse princípio, avalia a tese segundo a qual a dádiva é fundamento de toda sociabilidade e comunicação humanas, assim como sua presença e sua diferente institucionalização em várias sociedades analisadas por Mauss, capitalistas e não-capitalistas.

    Se muestra cómo pueden darse las polémicas en la inmanencia de la ficción proustiana y teñidas, por tanto, de esta: 1) a través de las mutaciones producidas en la obra polemiza contra sí mismo; 2) el paradigma de la libertad del lector permite polemizar en el establecimiento de los textos. Algunas de las polémicas en la Recherche son contra: el arte imitativo; la autoridad del autor sobre el lector, la realidad pragmática, las convenciones lógicas, la posibilidad de enseñanza del arte, la nov...

    El presente trabajo retoma la cuestión de la incertidumbre de Proust en cuanto al género en el que escribiría su obra capital como punto de partida para distinguir en la totalidad de su obra dos formas de escritura que siguen procedimientos diferentes. Sostengo que esa utilización de procedimientos diferentes tiene consecuencias en cuanto a que condiciona la posibilidad de arribar o no a afirmaciones concluyentes. Departamento de Filosofía

    La finalidad de este trabajo es intentar una aproximación al núcleo ontológico de la incógnita humana; esto es, a ese horizonte donde se confunden las fronteras teóricas de las variadas disciplinas que convergen en la Antropología y justifican en último término su validez objetiva. El hombre es un proyecto en ejecución, un quehacer, al go que se está realizando en un espacio tiempo; homo inabsolutus, peregrino y caminante que busca el Ser, del que tiene una referencia intuitiva; sus huellas...

    A medicina tradicionalmente vigente no Ocidente se baseava na classificação da heterogeneidade humana em diversos tipologias (compleições). Com a formulação da ciência moderna, gradualmente, a base da medicina passou a focar os fenômenos físicos e químicos que ocorrem na matéria viva. Assim, a prática clínica passa a depender do diagnóstico de entidades nosológicas, classificadas segundo seu mecanismo etiopatogênico, por sua vez, dependente de mecanismos biomoleculares. N...

    我们往往从"达达"主义的角度理解杜尚的艺术,然而作为后现代主义之父的杜尚,他主要是在时效性上具有"达达"主义的意义.除了象一个革命者那样善于改造和推翻,从个体的创作角度看,杜尚的艺术是建立在个人对世界的私密性体验和"绝对的好奇心之上"的,是人之为人的快乐.在他的作品中更多的揭示了谜一样的生存体验,具有强烈的超现实意味.

    Full Text Available This article offers a theoretical debate regarding the origins of cannibalism based on the writings of Christopher Columbus. The manner in which the cannibal was constructed is of vital importance to understand the arguments later used to justify not only the conquest of the Caribbean but also to legitimize the stigmatization of Amerindian groups accused of consuming human fesh.
