    Niels Reeh was highly regarded for his contributions to glaciology, specifically through his rigorous combination of numerical modelling and field observations. In 1966 he began his work on the application of beam mechanics to floating glaciers and ice shelves and throughout his life, Niels retained a strong interest in modelling glacier dynamics. In the early 1980s Niels developed a 3D-model for ice sheets and in the late 1980s an advanced flow-line model. Niels Reeh also took part in the early ice-core drilling efforts in Greenland and later pioneered the concept of retrieving similar records from the surface of the ice-sheet margin. Mass balance of glaciers and ice sheets was another theme in Niels Reeh’s research, with a number of important contributions and insights still used when teaching the subject to students. Niels developed elegant models for ablation and snow densification, notable for their applicability in large-scale ice-sheet models and studied the impact of climate change on ice sheets and glaciers. Niels also took his interest in ice-dynamics and mass balance into remote sensing and worked successfully on methods to utilize radar and laser data from airborne surveys and satellites in glaciology. In this, he pioneered the combination of field experiments, satellite observations and numerical modelling to solve problems on the Greenland Ice Sheet. In this presentation we will attempt to provide an overview of Niels Reeh’s many-facetted career in acknowledgement of his contributions to the field of glaciology.

  11. Niels Bohr and Complementarity An Introduction

    CERN Document Server

    Plotnitsky, Arkady

    2012-01-01

    This book offers a discussion of Niels Bohr’s conception of “complementarity,” arguably his greatest contribution to physics and philosophy. By tracing Bohr’s work from his 1913 atomic theory to the introduction and then refinement of the idea of complementarity, and by explicating different meanings of “complementarity” in Bohr and the relationships between it and Bohr’s other concepts, the book aims to offer a contained and accessible, and yet sufficiently comprehensive account of Bohr’s work on complementarity and its significance.

  12. The HERMES recoil detector

    International Nuclear Information System (INIS)

    Airapetian, A.; Belostotski, S.

    2013-02-01

    For the final running period of HERA, a recoil detector was installed at the HERMES experiment to improve measurements of hard exclusive processes in charged-lepton nucleon scattering. Here, deeply virtual Compton scattering is of particular interest as this process provides constraints on generalised parton distributions that give access to the total angular momenta of quarks within the nucleon. The HERMES recoil detector was designed to improve the selection of exclusive events by a direct measurement of the four-momentum of the recoiling particle. It consisted of three components: two layers of double-sided silicon strip sensors inside the HERA beam vacuum, a two-barrel scintillating fibre tracker, and a photon detector. All sub-detectors were located inside a solenoidal magnetic field with an integrated field strength of 1Tm. The recoil detector was installed in late 2005. After the commissioning of all components was finished in September 2006, it operated stably until the end of data taking at HERA end of June 2007. The present paper gives a brief overview of the physics processes of interest and the general detector design. The recoil detector components, their calibration, the momentum reconstruction of charged particles, and the event selection are described in detail. The paper closes with a summary of the performance of the detection system.

    NASAs Hall Effect Rocket with Magnetic Shielding (HERMeS) 12.5 kW Technology Demonstration Unit-1 (TDU-1) Hall thruster has been the subject of extensive technology maturation in preparation for development into a flight ready propulsion system. Part of the technology maturation was to test the TDU-1 thruster in several ground based electrical configurations to assess the thruster robustness and suitability to successful in-space operation. The ground based electrical configuration testing has recently been demonstrated as an important step in understanding and assessing how a Hall thruster may operate differently in space compared to ground based testing, and to determine the best configuration to conduct development and qualification testing. This presentation will cover the electrical configuration testing of the TDU-1 HERMeS Hall thruster in NASA Glenn Research Centers Vacuum Facility 5. The three electrical configurations examined are the thruster body tied to facility ground, thruster floating, and finally the thruster body electrically tied to cathode common. The TDU-1 HERMeS was configured with two different exit plane boundary conditions, dielectric and conducting, to examine the influence on the electrical configuration characterization.

  15. Overview of HERMES results

    Directory of Open Access Journals (Sweden)

    Van Hulse Charlotte

    2016-01-01

    Full Text Available The HERMES experiment has collected a wealth of deep-inelastic scattering data using the 27.6 GeV polarized lepton beam at HERA and various pure gas targets, both unpolarized and polarized. This allowed for a series of diverse and unique measurements. Among them are measurements that provide information on the threedimensional structure of the nucleon, both in momentum space and in position space. Results of measurements of exclusive ω production on an unpolarized and transversely polarized nucleon target, sensitive to the distribution in transverse-position and longitudinalmomentum space, are discussed as well as the three-dimensional extraction of azimuthal asymmetries measured in semi-inclusive deep-inelastic scattering, sensitive to twist-2 and twist-3 distributions in three-dimensional momentum space.

  16. Complementarity beyond physics Niels Bohr's parallels

    CERN Document Server

    Bala, Arun

    2017-01-01

    In this study Arun Bala examines the implications that Niels Bohr’s principle of complementarity holds for fields beyond physics. Bohr, one of the founding figures of modern quantum physics, argued that the principle of complementarity he proposed for understanding atomic processes has parallels in psychology, biology, and social science, as well as in Buddhist and Taoist thought. But Bohr failed to offer any explanation for why complementarity might extend beyond physics, and his claims have been widely rejected by scientists as empty speculation. Scientific scepticism has only been reinforced by the naïve enthusiasm of postmodern relativists and New Age intuitionists, who seize upon Bohr’s ideas to justify anti-realist and mystical positions. Arun Bala offers a detailed defence of Bohr’s claim that complementarity has far-reaching implications for the biological and social sciences, as well as for comparative philosophies of science, by explaining Bohr’s parallels as responses to the omnipresence...

    To support the operation of the HERMeS 12.5 kW Hall Thruster for NASA's Asteroid Redirect Robotic Mission, hollow cathodes using emitters based on barium oxide impregnate and lanthanum hexaboride are being evaluated through wear-testing, performance characterization, plasma modeling, and review of integration requirements. This presentation will present the development approach used to assess the cathode emitter options. A 2,000-hour wear-test of development model Barium Oxide (BaO) hollow cathode is being performed as part of the development plan. Specifically this test is to identify potential impacts cathode emitter life during operation in the HERMeS thruster. The cathode was operated with a magnetic field-equipped anode that simulates the HERMeS hall thruster operating environment. Cathode discharge performance has been stable with the device accumulating 743 hours at the time of this report. Observed voltage changes are attributed to keeper surface condition changes during testing. Cathode behavior during characterization sweeps exhibited stable behavior, including cathode temperature. The details of the cathode assembly operation of the wear-test will be presented.

  9. N Deposition Effects on Hermes Copper Butterfly (Lycaena hermes) Habitat in Southern California

    Malter, L. I.; Vourlitis, G. L.

    2017-12-01

    Atmospheric nitrogen (N) deposition has become a global concern over the past few decades as population sizes have increased. San Diego County, CA, USA, with a high population density, Mediterranean-type climate, and high biodiversity, is an ideal site for an extensive N deposition study. Chronic anthropogenic N deposition is one of the main contributing factors to affect plant species diversity (Vourlitis and Pasquini 2009) and invasive species encroachment (Minnich and Dezzani 1998). It is also the location of the rare endemic Hermes copper butterfly (Lycaena hermes), which has received minimal research and remains a mystery to many ecologists. We hypothesized that N deposition will impact Hermes abundance; however, there is limited research on the effects of N deposition on butterfly habitat. Thus, this study aims to determine the effect of increased N on the alterations to plant-insect interactions. These effects are being measured at five sites throughout San Diego County in current or historical Hermes copper habitat. N deposition collectors have been placed under the canopy of spiny redberry shrubs (Rhamnus crocea) to accumulate N throughfall at each site. Soil and redberry stem fragments are being used to analyze total N and Carbon (C), water potential, and shrub growth throughout the course of this study. Despite the preliminary nature of our results, we show a number of trends between data groups, such as large differences in soil and tissue N and C between the study sites, suggesting differences in atmospheric N inputs. These variations in soil N availability lead to variations in leaf tissue chemistry, which can ultimately impact the performance of the Hermes copper larvae. Our current data demonstrate some clear trends, but whether these trends remain consistent and interpretable remains to be seen. We anticipate this research will increase our understanding of spatial variation patterns of N deposition in southern California and how that N input might

  11. Paul Ehrenfest, Niels Bohr, and Albert Einstein: Colleagues and Friends

    Science.gov (United States)

    Klein, Martin J.

    2010-09-01

    In May 1918 Paul Ehrenfest received a monograph from Niels Bohr in which Bohr had used Ehrenfest's adiabatic principle as an essential assumption for understanding atomic structure. Ehrenfest responded by inviting Bohr, whom he had never met, to give a talk at a meeting in Leiden in late April 1919, which Bohr accepted; he lived with Ehrenfest, his mathematician wife Tatyana, and their young family for two weeks. Albert Einstein was unable to attend this meeting, but in October 1919 he visited his old friend Ehrenfest and his family in Leiden, where Ehrenfest told him how much he had enjoyed and profited from Bohr's visit. Einstein first met Bohr when Bohr gave a lecture in Berlin at the end of April 1920, and the two immediately proclaimed unbounded admiration for each other as physicists and as human beings. Ehrenfest hoped that he and they would meet at the Third Solvay Conference in Brussels in early April 1921, but his hope was unfulfilled. Einstein, the only physicist from Germany who was invited to it in this bitter postwar atmosphere, decided instead to accompany Chaim Weizmann on a trip to the United States to help raise money for the new Hebrew University in Jerusalem. Bohr became so overworked with the planning and construction of his new Institute for Theoretical Physics in Copenhagen that he could only draft the first part of his Solvay report and ask Ehrenfest to present it, which Ehrenfest agreed to do following the presentation of his own report. After recovering his strength, Bohr invited Ehrenfest to give a lecture in Copenhagen that fall, and Ehrenfest, battling his deep-seated self-doubts, spent three weeks in Copenhagen in December 1921 accompanied by his daughter Tanya and her future husband, the two Ehrenfests staying with the Bohrs in their apartment in Bohr's new Institute for Theoretical Physics. Immediately after leaving Copenhagen, Ehrenfest wrote to Einstein, telling him once again that Bohr was a prodigious physicist, and again

  13. Exclusive φ meson production in HERMES

    International Nuclear Information System (INIS)

    Golembiovskaya, Mayya

    2014-03-01

    In the present work exclusive φ meson leptoproduction at HERMES experiment in DESY was studied using the data collected at HERA accelerator in the period from 1998 till 2000 and from 2006 till 2007 years. In the analysis unpolarized and longitudinally polarized hydrogen and deuteron targets were used, the beam consisted of longitudinally polarized leptons. Via measurement of the angular and momentum distribution of the φ meson decay products 23 spin density matrix elements (SDMEs) for the φ meson were obtained. The number of SDMEs was defined by the experiment conditions, e.g. by the beam and target polarization directions. For the mentioned time period φ meson SDMEs were defined at HERMES for the first time. The quantities U 1 , U 2 and U 3 which can be used to check presence of unnatural parity exchange (UPE) mechanism in phi meson production were calculated from SDMEs. All the results were obtained in 3 kinematic bins of Q 2 , 4 kinematic bins of t' and for the integrated kinematics. No statistically significant difference between the results for hydrogen and deuteron targets was observed. The UPE quantities were found to be zero within 2 σ for the integrated kinematics, indicating negligible contribution of UPE for the φ meson production which is in agreement with theory predictions. The test of s-channel helicity conservation hypothesis via comparison of corresponding SDME values showed helicity conservation for the φ meson production.

    The HERMES experiment emphasizes measurements of semi-inclusive deep-inelastic scattering. Most of the hadrons produced lie between 2 and 10 GeV, a region in which it had not previously been feasible to separate pions, kaons, and protons with standard particle identification (PID) techniques. The recent development of new clear, large, homogeneous and hydrophobic silica aerogel material with a low index of refraction offered the means to apply RICH PID techniques to this difficult momentum region. The HERMES instrument uses two radiators, C sub 4 F sub 1 sub 0 , a heavy fluorocarbon gas, and a wall of silica aerogel tiles. A lightweight spherical mirror constructed using a newly perfected technique to make resin-coated carbon-fiber surfaces of optical quality provides optical focusing on a photon detector consisting of 1934 photomultiplier tubes (PMT) for each detector half. The PMT array is held in a soft steel matrix to provide shielding against the residual field of the main spectrometer magnet. Ring recon...

    1996-01-01

    Software development for the HERMES experiment faces the challenges of many other experiments in modern High Energy Physics: Complex data structures and relationships have to be processed at high I/O rate. Experimental control and data analysis are done on a distributed environment of CPUs with various operating systems and requires access to different time dependent databases like calibration and geometry. Slow and experimental control have a need for flexible inter-process-communication. Program development is done in different programming languages where interfaces to the libraries should not restrict the capacities of the language. The needs of handling complex data structures are fulfilled by the ADAMO entity relationship model. Mixed language programming can be provided using the CFORTRAN package. DAD, the Distributed ADAMO Database library, was developed to provide the I/O and database functionality requirements. (author)

    In this thesis the exclusive electroproduction of ρ 0 mesons is analyzed using the data accumulated with the HERMES spectrometer in the years 2002-2005 by scattering the lepton beam of the HERA accelerator of the internal target of HERMES filled with transversely polarized hydrogen gas atoms. The ρ 0 production mechanism and, in a model-dependent way, the structure of the nucleon are studied by measuring the spin-density matrix elements (SDMEs), which parameterize the ρ 0 production and decay angular distribution. The decomposition of the angular distribution in terms of SDMEs was previously done for both polarized and unpolarized lepton beam and unpolarized target. Recently, the angular distribution was decomposed in terms of SDMEs also for a transversely polarized target. A first measurement of the 30 'transverse' SDMEs is reported in this thesis, yielding information on the degree of s-channel helicity conservation and natural-parity exchange in the case of a transversely polarized target. The measured SDMEs are implemented into the rhoMC Monte Carlo generator, which is currently the only one capable of fully simulating the exclusive ρ 0 production and decay for both unpolarized and polarized beam and target. The interest in SDMEs for a polarized target arose after it was shown that at leading twist the corresponding SDMEs can be related to the azimuthal transverse target-spin asymmetry in the cross section of exclusive ρ 0 production which is sensitive to the unknown nucleon helicity-ip GPDs. Since the GPD formalism is only valid for longitudinally polarized vector mesons produced by longitudinal photons, for the first time the transverse target-spin asymmetry of longitudinally polarized ρ 0 mesons is extracted and compared to the available theoretical predictions, specically considering possible problems with next-to-leading order corrections.

    Full Text Available Open source software is software designed to allow anyone to use and make changes in the software. This practice often renders the product superior to more centralized models such as those used in commercial software companies. How is such a phenomenon possible in a time where nothing seems to be acquirable save by purchase? Niels C. TAUBERT's book Productive Anarchy? Networks of Open Source Software Development aims at a sociological understanding of the prerequisites and conditions for the success of open source software. One of the conclusions of TAUBERT's book is that the process of open software development needs to be understood as adaptive and experimental. A continuous feedback between the context of production and the context of application is the basis for robust and successful software production. One of the surprising results of the book is that the most important requirement for this feedback process is a set of norms—neutrality, communism, disinterestedness, and universalism—norms that Robert MERTON associated with academic science in the 1940s. If TAUBERT is right that these norms are to be found outside the world of institutional science in open source software development projects today, then his case study can be seen as an indicator for a new form of knowledge production in the 21st century, where the social relevance and responsibility of a research process are keys to successful innovation. With this book, which deserves a wide readership, TAUBERT makes an important contribution to our understanding of the successful organization of technology development.

    2011-01-01

    The non-ionizing energy loss (NIEL) values for protons in solar cells should be modified by taking into account the distribution of the Bragg damage peak in the active region to calculate the corresponding displacement damage dose. In this paper, based upon a thin target approximation, a new approach is presented to modify NIEL values for protons on a GaAs sub-cell. Adjusted NIEL values can be used to estimate the degradation induced by protons on GaInP/GaAs/Ge triple-junction space solar cells.

    Full Text Available This January, while preparing a new course, Robert Seydel was struck and killed by an unexpected heart attack. He was a critically under-appreciated artist and one of the most beloved and admired professors at Hampshire College.At the time of his passing, Seydel was on the brink of a major artistic and career milestone. His Book of Ruth was being prepared for publication by Siglio Press. His publisher describes the book as: “an alchemical assemblage that composes the life of his alter ego, Ruth Greisman— spinster, Sunday painter, and friend to Joseph Cornell and Marcel Duchamp. Through collages, drawings, and journal entries from Ruth’s imagined life, Seydel invokes her interior world in novelistic rhythms.”This convergence of his professional triumph with the tragedy of his death makes now a particularly appropriate time to think about Robert Seydel and his work. This feature contains a selection of excerpts from Book of Ruth (courtesy of Siglio Press alongside a pair of texts remembering him and giving critical and biographical insights into his art and his person. These texts, from a former student and a colleague respectively, were originally prepared for Seydel's memorial at Hampshire College and have since been revised for publication in continent.

  4. The HERMES recoil photon-detector and nuclear p{sub t}-Broadening at HERMES

    Haarlem, Y. van

    2007-09-15

    The first part of this work consists of hardware research and development done in order to construct and test a photon-detector as one of the three detectors of the HERMES recoil detector. The HERMES recoil detector consists of a target cell, a silicon-detector, a scintillating fiber tracker, and a photon-detector. All are inside a super-conducting magnet. The silicon detector uses energy deposition to determine the momentum of the particle because in its energy range the energy deposition is an unambiguous function of the momentum of the particle. The scintillating fiber tracker is located outside the beam-vacuum and is surrounded by the photon-detector. It consists of two barrels with layers of scintillating fibers. It detects particles by converting their energy deposition into light. It measures two space points of a charged particle and from the bending of the assigned track (in the magnetic field provided by the super-conducting magnet) a momentum measurement can be derived. The photon-detector is located between the scintillating fiber tracker and the magnet. It consists (from the inside out) of three layers of tungsten showering material followed by scintillating strips. The second part of this work is an analysis performed concerning the transverse momentum broadening of hadrons produced in deep-inelastic scattering on a nuclear target compared to a D target.

    This book gives a detailed study of the development and the interpretation given to Niels Bohr's Principle of Correspondence. It also describes the role that this principle played in guiding Bohr's research over the critical period from 1920 to 1927. Quantum mechanics, developed in the 1920s and 1930s by Bohr, Heisenberg, Born, Schrödinger and Dirac, represents one of the most profound turning points in science. This theory required a wholly new kind of physics in which many of the principles, concepts and models representing reality, that had formed the basis of classical physics since Galileo and Newton, had to be abandoned. This book re-examines the birth of quantum mechanics, in particular examining the development of crucial and original insights of Niels Bohr.

    Niels Bohr and Philosophy of Physics: Twenty-First Century Perspectives examines the philosophical views, influences and legacy of the Nobel Prize physicist and philosophical spokesman of the quantum revolution, Niels Bohr. The sixteen contributions in this collection by some of the best contemporary philosophers and physicists writing on Bohr's philosophy today all carefully distinguish his subtle and unique interpretation of quantum mechanics from views often imputed to him under the banner of the “Copenhagen Interpretation.” With respect to philosophical influences on Bohr's outlook, the contributors analyse prominent similarities between his viewpoint and Kantian ways of thinking, the views of the Danish philosopher Harald Høffding, and themes characteristic of American pragmatism. In recognizing the importance of Bohr's epistemological naturalism they examine his defence of the indispensability of classical concepts from a variety of different perspectives. This collection shows us that Bohr's int...

    1999-01-01

    A NIEL (non-ionizing-energy-loss) spectrometer for the Mir space station is described. The NIEL spectrometer package contained 20 GaAs LEDs, 10 SiC LEDs and 13 locations for TLD-700s. In order to probe different energy regions of the radiation field, the package is divided into 4 compartments covered by absorbers of varying thicknesses. This device has been submitted to proton irradiation. The effects on both the response time and the intensity of the light were measured as a function of the fluence. One of the advantages of LEDs as radiation monitors is their sensitivity and it is shown that it would be possible to detect a fluence of 4*10 7 p/cm 2 of 10 MeV protons, with sensitivity scaled as 1/E for other energies.

    2008-10-15

    The HERMES experiment was a forward angle spectrometer on the HERA storage ring at DESY, Hamburg, Germany. HERMES successfully increased understanding of the ''spin puzzle'', the spin structure of the nucleon, by providing high precision measurements of {delta}{sigma} in the Quark Parton Model, the fraction of the spin carried by the current quarks. Following the link of another piece of the puzzle, the orbital angular momentum of quarks and gluons, to the Generalised Parton Distribution (GPD) theoretical framework, HERMES focused on measurements of the Deeply Virtual Compton Scattering (DVCS) process. These measurements are sensitive to GPDs, allowing further experimental constraints to be made on the components of nucleon spin. In the Winter shutdown period 2005-2006 HERMES was upgraded with a Recoil Detector in the target region. This allowed the experiment to make exclusive measurements of the DVCS process for the rst time, reducing background and increasing the resolution of various kinematic variables. The method for reconstructing particle tracks in the inhomogeneous magnetic eld is investigated here. DVCS o a deuterium target is measured with all available data prior to the installation of the Recoil Detector. A comparison is made to currently available models of spin-(1)/(2) GPDs. This analysis has been approved for publication by the HERMES collaboration. The data is further employed in an investigation of a model dependent constraint of the total angular momentum of up and down quarks in the nucleon. (orig.)

    A keynote speaker at Outlook 2001 conference, Robert Priddle, Executive Director of the International Energy Agency, provided a realistic assessment of the opportunities for a change in the energy supply mix in the light of the growing international debate about the design of a sustainable energy future. World energy supply today is based firmly on fossil fuels. Furthermore, projections of future supply, such as that made in the reference case of the recent World Energy Outlook by the IEA, indicate little change. Yet government's remain deeply engaged in efforts to reshape energy markets including (despite the failure of COP-6 in The Hague last November) efforts to curb national emissions of greenhouse gases, in particular from the energy sector. Australia has made considerable progress in developing and applying life cycle analysis to the energy sector. This effort demonstrates opportunities to combine, for example, coal seam methane capture, coal and biomass co-combustion, coal power generation and steel production and thus to reduce emissions by up to 15%. The prospect is that even with effective carbon constraints reflected in fuel prices, coal can remain a competitive fuel choice for longer than many analysts imagine. The outcome does not rely on exotic technology development, rather it requires the necessary market signals to create new business partnerships

    Danish reformer Niels Hemmingsen was a Lutheran, but owing to Pan-Protestant sentiments that became apparent in his later writings, he found an appreciative audience in non-Lutheran Western Europe during the late sixteenth and early seventeenth centuries. This article argues that the early modern...... European reception of Hemmingsen and his theology should be seen as an attempt to construct him as part of a Protestant memory. It also argues that in order to understand the dynamics behind the reception of Hemmingsen’s ideas, one has to consider the geopolitics of early modern Denmark. Due to her...

    Niels Bohr è una figura centrale nella fisica del Novecento, padre fondatore della teoria atomica e della meccanica quantistica. La storia della sua vita, ricca e piena anche sul piano affettivo e personale, non può dunque ridursi a un resoconto dei suoi successi scientifici e Pais, allievo e poi amico di Bohr, ne è perfettamente consapevole. Il libro si sviluppa su vari piani: capitoli strettamente biografici o storico-scientifici si alternano a discussioni sulle idee di Bohr in campo politico e filosofico, sui suoi rapporti con Einstein, sul suo ruolo nei drammatici anni della guerra e su molti altri aspetti della vicenda umana.

    2010-03-01

    This thesis details the simultaneous extraction of three polarisation-dependent asymmetries in the distribution of real photons from the ep→epγ interaction and its indistinguishable deeply virtual Compton scattering and Bethe-Heitler processes at the HERMES fixed-target experiment at Desy. The data analysed were taken using a longitudinally polarised 27.57 GeV positron beam incident on a longitudinally polarised hydrogen gas target. The extracted asymmetries include two single-spin asymmetries A UL and A LU which depend on the polarisation of the target and beam respectively, averaged over all other polarisation states. The double-spin asymmetry A LL dependent on the product of the beam and target polarisations is extracted for the first time. The asymmetry amplitudes extracted relate to combinations of Generalised Parton Distributions (GPDs), predominantly H and H. The extracted amplitudes are presented across the HERMES kinematic range alongside theoretical predictions from a GPD model based on double distributions. Large sin φ and cos(0φ) amplitudes are observed for A UL and A LL respectively, with an unexpectedly large sin(2φ) amplitude for A UL . The results for the A UL and A LL asymmetries are broadly compatible with theory predictions, and the extracted A LU amplitudes are compatible with HERMES results extracted from a significantly larger data set. It is foreseen that these results will form input to future global data-based GPD models which aim to provide a better understanding of GPDs. (orig.)

    2017-01-01

    This is the first comprehensive book on the European Hermes program. It tells the fascinating story of how Europe aimed for an independent manned spaceflight capability which was to complement US and Soviet/Russian space activities.In 1975, France decided to expand its plans for automated satellites for materials processing to include the development of a small 10 ton spaceplane to be launched on top of a future heavy-lifting Ariane rocket. This Hermes spaceplane would give Europe its own human spaceflight capability for shuttling crews between Earth and space stations. The European Space Agency backed the proposal. Unfortunately, after detailed studies, the project was cancelled in 1993. If Hermes had been introduced into service, it could have become the preferred "space taxi" for ferrying crews to and from the International Space Station. But that opportunity was lost. This book provides the first look of the complete story of and reasons for the demise of this ambitious program. It also gives an account w...

    1993-01-01

    This study falls within the framework of the incorporation of quantitative risk assessment to the activities planned for the ESA-HERMES project (ESA/ CNES). The main objective behind the study was the analysis and evaluation of the potential contribution of so-called probabilistic or quantitative safety analysis to the optimization of the safety development process for the systems carrying out the safety functions required by the new and complex HERMES Space Vehicle. For this purpose, a pilot study was considered a good start in quantitative safety assessments (QSA), as this approach has been frequently used in the past to establish a solid base in large-scale QSA application programs while avoiding considerable economic risks. It was finally decided to select the HERMES docking/berthing system with Man Tender Free Flyer as the case-study. This report describes the different steps followed in the study, along with the main insights obtained and the general conclusions drawn from the study results. (author)

    Upon purification, an N-terminally deleted version of the Hermes transposase exists in solution as a mixture of two species that are approximately hexameric and dimeric. Crystals have been obtained of the smaller species that diffract to 2.1 Å resolution. DNA transposition is the movement of a defined segment of DNA from one location to another. Although the enzymes that catalyze transposition in bacterial systems have been well characterized, much less is known about the families of transposase enzymes that function in higher organisms. Active transposons have been identified in many insect species, providing tools for gene identification and offering the possibility of altering the genotypes of natural insect populations. One of these active transposons is Hermes, a 2749-base-pair element from Musca domestica that encodes its own transposase. An N-terminally deleted version of the Hermes transposase (residues 79–612) has been overexpressed and purified, and crystals that diffract to 2.1 Å resolution have been obtained at 277 K by the hanging-drop method

    2013-01-01

    Niels Bohr ranks with Einstein among the physicists of the 20th century. He rose to this status through his invention of the quantum theory of the atom and his leadership in its defense and development. He also ranks with Einstein in his humanism and his sense of responsibility to his science and the society that enabled him to create it. Our book presents unpublished excerpts from extensive correspondence between Bohr and his immediate family, and uses it to describe and analyze the psychological and cultural background to his invention. The book also contains a reprinting of the three papers of 1913 - the "Trilogy" - in which Bohr worked out the provisional basis of a quantum theory of the atom.

    2013-07-01

    In 1665 the Danish scholar Niels Stensen (1638-1686) reached Paris, where he pronounced a discourse on brain anatomy that was to orient neuroscientists for years to come. In his lecture, Stensen rejected ancient speculations about animal spirits and criticized René Descartes and his followers who, despite a poor knowledge of brain anatomy, elaborated complex models to explain the multifaceted function of what he considered the principal organ of the human mind. He advocated the need for studying the brain through a comparative, developmental and pathological convergent approach and called for appropriate dissection methods and accurate illustrations. His own careful anatomical studies permitted him to precisely depict many brain structures. After pioneering works in paleontology and geology, he devoted himself to theology. In 1677 Stensen converted from Lutheranism to Catholicism and, while working relentlessly as a bishop and apostolic vicar in Northern Europe, he died in self-imposed poverty at age 48.

    2004-01-01

    Nearly 20 years before Einstein, Niels Bjern developed a theory of gravity based on what is today known as the equivalence principle - but naturally without invoking the ideas of the special relativity theory. Bjern predicted almost all the effects considered to be tests for general relativity, his calculation formulas for the effects being identical to those of general relativity. An advocate of the absolute space concept, Bjern described the gravitational field in terms of the field of absolute velocities of an inertial space. He only used the ideas of general relativity to describe the precession of the perihelion of Mercury. The reason why Bjern's predictions and those of general relativity are identical is discussed.

  14. Deeply virtual Compton scattering off longitudinally polarised protons at HERMES

    2010-06-15

    This thesis details the simultaneous extraction of three polarisation-dependent asymmetries in the distribution of real photons from the ep{yields}ep{gamma} interaction and its indistinguishable deeply virtual Compton scattering and Bethe-Heitler processes at the HERMES fixed-target experiment at Desy. The data analysed were taken using a longitudinally polarised 27.57 GeV positron beam incident on a longitudinally polarised hydrogen gas target. The extracted asymmetries include two single-spin asymmetries A{sub UL} and A{sub LU} which depend on the polarisation of the target and beam respectively, averaged over all other polarisation states. The double-spin asymmetry A{sub LL} dependent on the product of the beam and target polarisations is extracted for the first time. The asymmetry amplitudes extracted relate to combinations of Generalised Parton Distributions (GPDs), predominantly H and H. The extracted amplitudes are presented across the HERMES kinematic range alongside theoretical predictions from a GPD model based on double distributions. Large sin {phi} and cos(0{phi}) amplitudes are observed for A{sub UL} and A{sub LL} respectively, with an unexpectedly large sin(2{phi}) amplitude for A{sub UL}. The results for the A{sub UL} and A{sub LL} asymmetries are broadly compatible with theory predictions, and the extracted A{sub LU} amplitudes are compatible with HERMES results extracted from a significantly larger data set. It is foreseen that these results will form input to future global data-based GPD models which aim to provide a better understanding of GPDs. (orig.)

    The reconstruction of the missing mass is limited by the position and momentum resolution of the HERMES spectrometer. In order to reach a higher accuracy in the measurements the backscattered nucleon must also be detected. A detector suited for this must give the possibility, to determine the momentum of the particles over a very large range: from minimally ionizing particles up to protons, which are stopped in the detector. The detector must also be able to discriminate hadrons and mesons as well as cover the complete spatial region around the target. In the winter 2005-2006 such a recoil detector was installed in the HERMES experiment. The detector sonsists of three partial detectors, a silicon counter within the scattering chamber, a sintillating-fiber detector and a photon detector. Before the installation of the detector the silicon modules were tested in a bench test and checked together with the other particle detectors in a test experiment. A large part of this dissertation is dedicated to the planning and performance of these tests as well to the evaluation of them. It could be show, that the modules worked accordly to their specifications, however because of unexpectedly high noise a signal correction became necessary. Different models for the correction were developed and tested in the framework of these thesis. In spite of the high noise cosmic muons could be detected and their energy deposition measured with a signal-to-noise ratio of 2:1. In the winter break 2005-2006 the recoil detector was installed into the HERMES experiment. First diagnosis and analysis software was developed. The silicon detector measured successfully energy depositions of minimally ionizing particles up to protons stopped in the sensor. Minimally ionizing particles could be detected with a signal-to-noise ratio of 5:1. By means of track information of the scintillating-fiber detector protons could be discriminated from pions and other mesons by the silicon detector. The HERMES

    The presentation is concerned with higher twist corrections of nonpartonic origin to semi-inclusive observables in the kinematical region relevant for the HERMES experiment. We demonstrate a strong impact of the VDM-like interaction and the exclusive production of ρ 0 meson on the extraction of the (anti)d - (anti)u asymmetry from charged pion DIS multiplicities. We also show that it is the exclusive- ρ 0 channel which accounts for the experimentally observed effect of the excess of charged over neutral pions produced at large z. (author)

    The Hermes experiment (HERa MEasurement of Spin) at Desy was designed to study the spin structure of the nucleon in semi-inclusive deep inelastic scattering. The internal structure of the nucleon has been investigated in detail and it has been measured that the intrinsic quark spin contribution is only about 30% of the total spin of the nucleon. A formalism to describe the internal structure of the nucleon called Generalised Patron Distributions (GPDs) was developed recently to understand the fundamental structure of the nucleon. These GPDs can be accessed by the measurement of hard exclusive reactions and hard exclusive processes that can be understood in terms of GPDs. The accumulated Hermes data offer access to GPDs in different combinations of beam charge and beam and target helicity asymmetries. To improve exclusivity and to enhance the resolution of kinematic variables to study hard exclusive processes which provide access to the GPDs and hence to the orbital angular momentum of the quarks, in January 2006 a Recoil Detector was installed that surrounded the internal gas target of the Hermes experiment. The Hermes Recoil Detector consisted of three components: a silicon strip detector inside the vacuum, a scintillating fiber tracker and the photon detector. All three detectors were located inside a solenoidal magnet which provided a 1T longitudinal magnetic field. The Recoil Detector improves the selection of exclusive events by a direct measurement of the momentum and track position of the recoiling particle as well as by rejecting non-exclusive background. This detector was an ideal novel tool to combine energy and position measurements for charged particles in a momentum range of 0.1 to 1.4 GeV/c. The Recoil Detector was fully commissioned and operating. Data was taken continuously until the final Hera shutdown in July of 2007. In this thesis we report on the performance of the Recoil Detector and more specifically about the scintillating fiber tracker

    One of the interesting questions of Quantum Chromodynamics, the theory that governs the interactions between quarks and gluons, has been whether it is possible to observe hadrons which can not be explained as a combination of only two or three valence quarks. In numerous searches the existence of these exotic hadrons could not be confirmed. Recently, calculations based on the quark soliton model predicted the narrow exotic baryons {theta}{sup +} and {xi}{sup --}. A narrow resonance identified as the {theta}{sup +} was observed by several experiments at the predicted mass of 1540 MeV, but later followed by several dedicated experiments that could not confirm these positive results. At the HERMES experiment a search for the quasi-real photoproduction of the exotic baryon {theta}{sup +} on a deuterium target and the subsequent decay through pK{sup 0}{sub S} {yields} p{pi}{sup +}{pi}{sup -} revealed a narrow resonance in the pK{sup 0}{sub S} invariant mass distribution at 1528 MeV. In the search for the corresponding antiparticle {xi}{sup --} the result is consistent with zero events. In this thesis we present the search for the exotic baryon {xi}{sup --} on a deuterium target in the data sample used for the observation of the {theta}{sup +}. An upper limit on the cross section of the exotic baryon {xi}{sup --} is determined. The search for the exotic baryon {theta}{sup +} on hydrogen and deuterium targets at the HERMES experiment is extensively discussed. The event mixing method can be used to estimate the distribution of background events. Several difficulties with this method were addressed, but the background description in the case of the exotic baryon {theta}{sup +} remains unconvincing. Between the years 2002 and 2005 the HERMES experiment operated with a magnetic holding field around the hydrogen target. A method for the reconstruction of displaced vertices in this field was developed. The data collected during the years 2006 and 2007 offer an integrated

In numerous searches the existence of these exotic hadrons could not be confirmed. Recently, calculations based on the quark soliton model predicted the narrow exotic baryons Θ + and Ξ -- .

At the HERMES experiment a search for the quasi-real photoproduction of the exotic baryon Θ + on a deuterium target and the subsequent decay through pK 0 S → pπ + π - revealed a narrow resonance in the pK 0 S invariant mass distribution at 1528 MeV. In the search for the corresponding antiparticle Ξ -- the result is consistent with zero events.

    The High Efficiency and Resolution Multi Element Spectrograph (HERMES) is a four channel, VPH-grating spectrograph fed by two 400 fiber slit assemblies whose construction and commissioning has now been completed at the Anglo Australian Telescope (AAT). The size, weight, complexity, and scheduling constraints of the system necessitated that a fully integrated, deterministic, opto-mechanical alignment system be designed into the spectrograph before it was manufactured. This paper presents the principles about which the system was assembled and aligned, including the equipment and the metrology methods employed to complete the spectrograph integration.

    The contract for decommissioning the HERMES (Heavy Element and Radioactive Materials Electromagnetic Separator) Facility at AERE Harwell was the first contract of its type awarded to Private Industry by the Public Sector. The work required operatives to work in pressure suits for extended periods in decommissioning a heavily alpha contaminated facility. The work required the setting up of a temporary changeroom, waste posting facilities, air suit supplies and controls and temporary ventilation for a completely self-contained site set-up. The Contractor had to provide and train his own operatives, provide all health physics supervision and control and take full responsibility for all technical matters. (author)

    Experimental data for integrated kaon multiplicities taken at HERMES and COMPASS measurements look incompatible with each other. In this talk, we investigate the effects of hadron masses calculated at leading-order and leading twist at the kinematics of these two experiments. We present evidence that Hadron Mass Corrections can fully reconcile the data for the K+/K- multiplicity ratio, and can also sizeably reduce the apparent large discrepancy in the case of K++K- data. Residual differences in the shape of the latter one remains to be understood.

    A detector is described which measures the luminosity of the HERMES experiment at DESY. It is based on the coincident detection of electron-positron and photon pairs, or electron pairs, originating from the interaction of the beam positrons, or electrons, with the electrons of the atomic gas target. It consists of two calorimeters with radiation hard NaBi(WO sub 4) sub 2 crystals. Properties of the monitor, investigated in an electron test beam, and its performance in the experiment are presented.

    Within the key project "Herschel M 33 extended survey" (HerM33es), we are studying the physical and chemical processes driving star formation and galactic evolution in the nearby galaxy M 33, combining the study of local conditions affecting individual star formation with properties only becoming apparent on global scales. Here, we present recent results obtained by the HerM33es team. Combining Spitzer and Herschel data ranging from 3.6 μm to 500μm, along with H i, Hα, and GALEX UV data, we have studied the dust at high spatial resolutions of 150 pc, providing estimators of the total infrared (TIR) brightness and of the star formation rate. While the temperature of the warm dust at high brightness is driven by young massive stars, evolved stellar populations appear to drive the temperature of the cold dust. Plane-parallel models of photon dominated regions (PDRs) fail to reproduce fully the [C ii], [O i], and CO maps obtained in a first spectroscopic study of one 2' × 2' subregion of M 33, located on the inner, northern spiral arm and encompassing the H ii region BCLMP 302.

    The standard model of particle physics describes successfully the fundamental constituents and forces in our world; nevertheless, many details of the subatomic world are still beyond the scope of theoretical predictions. The internal structure of the nucleon has been investigated in detail and it was found that the nucleon spin budget, i.e. the composition of the nucleon spin by the spin and orbital angular momentum of quarks and gluons is not yet understood. It has been measured that the intrinsic quark spin contribution is only about 30% of the total spin of the nucleon. A recently developed formalism allows to describe the internal structure of the nucleon by so-called GPDs (Generalized Parton Distributions) in a more complete way than the previously used PDFs (Parton Density Functions). The GPDs are linked by the Ji sum rule to the angular momentum contributions of quarks and gluons. These GPDs can be accessed by the investigation of hard exclusive reactions. DVCS (deeply virtual Compton scattering) is the cleanest exclusive reaction to determine some of these distributions, using lepton beams with different helicity states and charges. HERMES (HERA measurements of spin) is one of the experiments which were carried out to complete the information about the nucleon spin budget. It is located at HERA which is an e ± -p-collider at DESY but uses only the polarized electron- and positron-beam, which is scattered off a gaseous internal target. The HERMES forward spectrometer consists of a set of detectors that are used for tracking, while another set of detectors provides information on particle identification and triggering. In the first phase of HERMES, only forward going particles were detected. Exclusive reactions have been measured using a missing invariant mass technique.

Here we show that Hermes/Rbpms interacts with nanos through sequence specific RNA localization signals found in the nanos-3′UTR. Importantly, Hermes/Rbpms specifically binds nanos, but not Vg1 RNA in the nucleus of stage I oocytes. In vitro binding data show that Hermes/Rbpms requires additional factors that are present in stage I oocytes in order to bind nanos1. One such factor may be hnRNP I, identified in a yeast-2-hybrid screen as directly interacting with Hermes/Rbpms. We suggest that Hermes/Rbpms functions as part of a RNP complex in the nucleus that facilitates selection of germline RNAs for germ plasm localization.

    This volume deals with Bohr's work on nuclear physics which began in the pre-1932 days with his thinking deeply, but inconclusively about the seeming contradictions then presented by the evidence about the nucleus. In 1936 Bohr recognized and described the insights provided by neutron scattering experiments and the excitement of this new understanding and its extension and consolidation occupied much of the subsequent years. In 1939 he was again first in understanding the essential features of the newly discovered phenomenon of fission, applying successfully the point of view of nuclear reactions which he had developed over the past three years. Later, in 1949-50, he was impressed by the success of the nuclear shell model, which on the face of it seemed hard to reconcile with the picture of the closely interacting nucleons which he had pioneered in 1936 and he put much effort into clarifying this paradox. As in earlier volumes the published papers are supported by appropriate selections from unpublished notes and drafts, and by relevant correspondence. CONTENTS: Foreword.

He died of recurrent apneas. The autopsy showed left sided multicystic dysplastic kidney and absence of one testis. Cytogenetic studies did not reveal any abnormality. The phenotypic features match those described in the Roberts-SC phocomelia syndrome. A literature review revealed that 50% of these patients have chromosomal defects and antenatal detection is possible on ultrasound and by chromosome analysis of the amniocytes.

    The transverse polarization of Λ(anti Λ) hyperons was measured in inclusive quasireal photoproduction for various target nuclei ranging from hydrogen to xenon. These data were taken at the HERMES Experiment at HERA/DESY using the 27.6 GeV lepton beam. They are compared to results from previous measurements of the HERMES experiment on hydrogen (H) and deuteron (D) targets. In comparison with earlier measurement a new improved track-fitting algorithm has been used leading to better vertex and momentum resolution. The HERMES data complement extensive transverse polarization studies of hyperons, using hadron beams.

Improved decay-particle reconstruction, more advanced particle identification, and increased event samples are employed. The structure that was observed earlier at an invariant mass of 1528 MeV shifts to 1522 MeV in the new analysis of data with a deuterium target, with a drop of statistical significance to about 2σ.

    To measure the spin structure of the nucleon, the HERMES experiment is planned at the HERA electron beam using a polarised internal gas target. A tracker is being built to reconstruct the vertex of the exciting particles. It consists of two drift chambers and two microstrip gas counter (MSGC) systems. The MSGC systems are housed into two gas gatight containers surrounding the beam pipe and located immediately after the exit flange of the target housing. The active area of the upper MSGC system covers an angular range of 40 mrad≤θ v ≤ 140 mrad by -170 mrad≤θ h ≤170 mrad. Below the beam pipe a second system is situated with the same acceptance. Each track within the acceptance is measured by two stations of three MSCGs having a strip orientation, of 0 , and +30 and -30 respectively with respect to the vertical axis. (HSI)

    The construction and use of a dual radiator Ring Imaging Cherenkov (RICH) detector is described. This instrument was developed for the HERMES experiment at DESY which emphasises measurements of semi-inclusive deep-inelastic scattering. It provides particle identification for pions, kaons, and protons in the momentum range from 2 to 15 GeV, which is essential to these studies. The instrument uses two radiators, C sub 4 F sub 1 sub 0 , a heavy fluorocarbon gas, and a wall of silica aerogel tiles. The use of aerogel in a RICH detector has only recently become possible with the development of clear, large, homogeneous and hydrophobic aerogel. A lightweight mirror was constructed using a newly perfected technique to make resin-coated carbon-fiber surfaces of optical quality. The photon detector consists of 1934 photomultiplier tubes (PMT) for each detector half, held in a soft steel matrix to provide shielding against the residual field of the main spectrometer magnet.

    Full Text Available La casa de invitados de Niels Bohr fue el primer edificio del arquitecto danés Vilhelm Wohlert (1920-2007. Arraigado a la tradición danesa, representa una renovación basada en la absorción de influencias extranjeras: la arquitectura americana y la tradición japonesa. La caja de madera tiene el carácter sensible de un organismo vivo, siempre cambiante según las variaciones de luz del día o temperatura. Puertas plegables y contraventanas generan extensiones de las habitaciones. Cuando se abren, crean una prolongación del espacio interior, que se extiende a la naturaleza circundante, y se expande hacia el espacio exterior, permitiendo su movilización. Se establece una arquitectura de flujos. Protagoniza un ejemplo de la modernidad como refinamiento en la técnica de los límites y la idea de que la arquitectura no es un objeto material, sino el espacio generado en su interior. Podría ser visto como un ikebana; “el arte del espacio”, donde se produce una circulación de aire entre sus componentes; algo vivo que expresa la tercera dimensión, el equilibrio asimétrico, un interés por la materia, su textura y efecto emocional que emana. Hay armonía y equilibrio, que transmiten serenidad y belleza; un encuentro con la naturaleza; un mundo de relaciones amable al ser humano.

  3. Exclusive {rho}{sup 0} production at HERMES

    Energy Technology Data Exchange (ETDEWEB)

    Rostomyan, Armine Armand

    2008-11-15

    In this thesis the exclusive electroproduction of {rho}{sup 0} mesons is analyzed using the data accumulated with the HERMES spectrometer in the years 2002-2005 by scattering the lepton beam of the HERA accelerator of the internal target of HERMES filled with transversely polarized hydrogen gas atoms. The {rho}{sup 0} production mechanism and, in a model-dependent way, the structure of the nucleon are studied by measuring the spin-density matrix elements (SDMEs), which parameterize the {rho}{sup 0} production and decay angular distribution. The decomposition of the angular distribution in terms of SDMEs was previously done for both polarized and unpolarized lepton beam and unpolarized target. Recently, the angular distribution was decomposed in terms of SDMEs also for a transversely polarized target. A first measurement of the 30 'transverse' SDMEs is reported in this thesis, yielding information on the degree of s-channel helicity conservation and natural-parity exchange in the case of a transversely polarized target. The measured SDMEs are implemented into the rhoMC Monte Carlo generator, which is currently the only one capable of fully simulating the exclusive {rho}{sup 0} production and decay for both unpolarized and polarized beam and target. The interest in SDMEs for a polarized target arose after it was shown that at leading twist the corresponding SDMEs can be related to the azimuthal transverse target-spin asymmetry in the cross section of exclusive {rho}{sup 0} production which is sensitive to the unknown nucleon helicity-ip GPDs. Since the GPD formalism is only valid for longitudinally polarized vector mesons produced by longitudinal photons, for the first time the transverse target-spin asymmetry of longitudinally polarized {rho}{sup 0} mesons is extracted and compared to the available theoretical predictions, specically considering possible problems with next-to-leading order corrections.

    Robert Hooke was a polymath whose expertise during the 17th century spanned many different scientific areas. As a schoolboy on the Isle of Wight he was obsessed with the possibility of human flight and later became equally absorbed in cosmology and planetary motion. His skills as an artist were put to good use both as an architect following the Great Fire of London and before that in Micrographia. Although that book is best known for demonstrating the power of Hooke's microscope, Micrographia describes distant planetary bodies, the wave theory of light, the organic origin of fossils, and various other philosophical and scientific interests of its author The following thumbnail sketches of Hooke reveal him to be a man of enormous energy and imagination whose ideas were often pirated or under-rated.

    Various descriptions of what would now be called Korsakoff Syndrome may be found in the medical literature predating the eponymous reports of Sergei Korsakoff (1854-1900) that date from 1887 onwards. Of these, it has been stated that the "most promising account" (Draaisma in Disturbances of the mind 163-164, 2009) may be that of Dr. Robert Lawson, published in 1878 in the journal Brain in its inaugural year of publication (Lawson in Brain 1:182-194, 1878). As Lawson is likely to be an unfamiliar name to most neurologists, and does not appear in the Oxford Dictionary of National Biography, we offer this brief account of his life and work.

    Many physicians are familiar with the parotid duct and the Danish physician/anatomist's name associated with it. However, most are unaware of Niels Stensen's life and his significant contributions to the early study of the brain. This physician of the Medici court was clearly ahead of his time and found errors in the publications of such giants as Varolius and Willis. The present review discusses the life of this seventeenth century anatomist, physician, and priest/bishop and highlights his contributions to neuroanatomy.

  10. Beam-induced depolarisation at the HERMES transversely polarised hydrogen target

    International Nuclear Information System (INIS)

    Tait, P.

    2006-01-01

    This thesis describes the polarised hydrogen target of the HERMES experiment at DESY in Hamburg. The HERMES target is based on hyperfine-splitting of hydrogen in an external magnetic field and provides nuclear-polarised hydrogen for the HERMES experiment. Particular emphasis is placed on the phenomenon of beam-induced depolarisation. The HERA electron beam consists of short bunches which produce a high-frequency magnetic field. A Fourier analysis of these bunches leads to a series of harmonics, based on the fundamental frequency of roughly 10.4 MHz, which can cause a transition between hyperfine states of the target atoms. Only through careful setting of the external magnetic field is it possible to avoid these transitions and the resulting depolarisation of the target gas. Measurements of these resonances were made during the first HERMES run 1995-2000. The target region was modified in 2001 to allow HERMES to use hydrogen polarised perpendicularly to the direction of the electron beam. This modification gave HERMES access to the so-called 'Transversity' distribution for the first time, but also allows additional resonances in the target, which were previously forbidden by selection rules. The measurement and minimisation of these 'Sigma resonances' are presented. A distinctive feature of the HERMES experiment is its novel storage cell which allows target atoms to make multiple passes of the HERA beam. An exact description of beam-induced depolarisation must therefore consider the geometry of the storage cell and the distribution of the magnetic field throughout the cell. Calculations of the depolarisation can be made by solving the time-dependent Schroedinger equation using first-order perturbation theory. A simple analytical model and a molecular-flow Monte-Carlo are used to predict the exact shape of the resonances. The first measurements of the resonances with a transverse magnetic holding field are presented and compared with the simulations. (orig.)

    The HERMES (high explosive response to mechanical stimulus) model was developed over the past decade to enable computer simulation of the mechanical and subsequent energetic response of explosives and propellants to mechanical insults such as impacts, perforations, drops, and falls. The model is embedded in computer simulation programs that solve the non-linear, large deformation equations of compressible solid and fluid flow in space and time. It is implemented as a user-defined model, which returns the updated stress tensor and composition that result from the simulation supplied strain tensor change. Although it is multi-phase, in that gas and solid species are present, it is single-velocity, in that the gas does not flow through the porous solid. More than 70 time-dependent variables are made available for additional analyses and plotting. The model encompasses a broad range of possible responses: mechanical damage with no energetic response, and a continuous spectrum of degrees of violence including delayed and prompt detonation. This paper describes the basic workings of the model.

    Full Text Available Este artigo propõe uma reflexão sobre o imaginário contemporâneo, tomando o design como vetor central e duas figuras míticas, Hermes e Prometeu, como coordenadas principais. De início, tecemos algumas considerações acerca das bases teóricas que amparam a abordagem aqui proposta e, em seguida, indicamos o modo como as figuras de Prometeu e Hermes conduzem boa parte da dinâmica sociocultural. Na sequência, analisamos o paradigma pós-prometeico que Bruno Latour identifica a partir de cinco conotações do termo design. Concluímos, por fim, que os mitos de Hermes e Prometeu se encontram implicados um no outro e que o design expressa, no imaginário contemporâneo, essa correlação.

    The HERMES (HERA measurement of spin) experiment is located in the eastern straight section of the HERA storage ring at DESY in Hamburg. It is designed to study the spin structure of the nucleons by deep inelastic scattering of polarized positrons resp. electrons provided by the HERA storage ring at 27.5 GeV impingingon the nucleons of internal polarized gas targets. The setup of the HERMES experiment is shown. First results are the measurement of the spin structure functions g 1 n with the polarized 3 He target (1995) and of g 1 p with polarized atomic hydrogen target, which was operated in 1996 and 1997. Beneath the inclusive physics, the possibility to detect and identify hadronic scattering products allows the measurement of semi-inclusive processes with the central item of the HERMES physics program.

    The HERMES experiment has measured double spin asymmetries in the cross section for deep-inelastic scattering of longitudinal polarized positrons off longitudinal polarized hydrogen and deuterium targets. From these asymmetries, based on inclusive and semi-inclusive measurements, polarized quark distributions were extracted as a function of x. Single-spin azimuthal asymmetries in semi-inclusive pion production were measured by the HERMES experiment for the first time, with a transversely polarized hydrogen target. Two different sine-dependencies were extracted which can be related to the quark transversity distribution h q 1 (x) and the Sivers function (Author)

  4. DVCS at HERMES. The recoil detector and transverse target spin asymmetries

    Energy Technology Data Exchange (ETDEWEB)

    Murray, M.J.

    2008-02-15

    The HERMES experiment is a large forward angle spectrometer located at the HERA accelerator ring at DESY, Hamburg. One of the most exciting topics studied at HERMES is Deeply Virtual Compton Scattering (DVCS) which is the simplest interaction that provides a gateway for access to Generalised Parton Distributions (GPDs). GPDs are a theoretical framework which can be used to calculate the total angular momentum of the quarks in the nucleon. As such, they provide one piece of the puzzle of nucleonic spin structure. In 2005, HERMES was upgraded in the target region with a Recoil Detector that allows it to make truly exclusive measurements of the DVCS interaction for the first time. The design and construction of the Recoil Detector is discussed herein, in addition to a complete analysis of the Transverse Target Spin Asymmetry (TTSA) in DVCS. Experimental facilities that enable measurement of this asymmetry are rare. The importance of the information on the TTSA from HERMES is made yet greater as the transversely polarised target that allows the asymmetry to be measured has been replaced by an unpolarised target. This was to allow the Recoil Detector to be installed. The final stage of this thesis shows a model-dependent method for constraining the angular momentum of the quarks in the nucleon and speculates as to the other pieces of the spin puzzle. (orig.)

  10. HERMES: A Model to Describe Deformation, Burning, Explosion, and Detonation

    Energy Technology Data Exchange (ETDEWEB)

    Reaugh, J E

    2011-11-22

    HERMES (High Explosive Response to MEchanical Stimulus) was developed to fill the need for a model to describe an explosive response of the type described as BVR (Burn to Violent Response) or HEVR (High Explosive Violent Response). Characteristically this response leaves a substantial amount of explosive unconsumed, the time to reaction is long, and the peak pressure developed is low. In contrast, detonations characteristically consume all explosive present, the time to reaction is short, and peak pressures are high. However, most of the previous models to describe explosive response were models for detonation. The earliest models to describe the response of explosives to mechanical stimulus in computer simulations were applied to intentional detonation (performance) of nearly ideal explosives. In this case, an ideal explosive is one with a vanishingly small reaction zone. A detonation is supersonic with respect to the undetonated explosive (reactant). The reactant cannot respond to the pressure of the detonation before the detonation front arrives, so the precise compressibility of the reactant does not matter. Further, the mesh sizes that were practical for the computer resources then available were large with respect to the reaction zone. As a result, methods then used to model detonations, known as {beta}-burn or program burn, were not intended to resolve the structure of the reaction zone. Instead, these methods spread the detonation front over a few finite-difference zones, in the same spirit that artificial viscosity is used to spread the shock front in inert materials over a few finite-difference zones. These methods are still widely used when the structure of the reaction zone and the build-up to detonation are unimportant. Later detonation models resolved the reaction zone. These models were applied both to performance, particularly as it is affected by the size of the charge, and to situations in which the stimulus was less than that needed for reliable

    Roberts syndrome is a rare disease, with multiple limb and skeletal abnormalities (called "pseudothalidomide disease"). There are only around 150 cases described in literature. We present a case of Roberts syndrome, diagnosed in moment of delivery, after a pregnancy without prenatal follow-up. The stillborn baby was naturally delivered by a 17-year-old primiparous woman at 38 weeks of amenorrhea. The pregnancy was not followed due to socioeconomic and family situation, and no prenatal ultrasound was performed. The male baby has 2650 g and presented several morphological abnormalities and tight double umbilical abdominal loop. The macroscopic evaluation showed: dolichocephaly, hypoplastic inferior maxilla with micrognathia, antimongoloid palpebral slant, pterygium colli, abnormal and lower implanted ears, superior limbs phocomelia, syndactyly at lower left limb and tetradactyly in all limbs, bilateral cryptorchidism, pancreatic aplasia. Roberts syndrome is a rare genetic disease with recessive autosomal transmission generated by mutations in ESCO2 gene, located on chromosome 8. The disease should be easy to diagnose by antenatal ultrasound examination, but in our case, the lack of prenatal follow-up determined the diagnostic at term. We believe consider this case is an argument towards introducing ultrasound-screening compulsory to all pregnancies. To identify a possible genetic mutation, further investigations of the parents are in progress, but classically the disease has a recessive autosomal transmission.

    The HERMES III accelerator, which is located at Sandia National Laboratories' Tech Area IV, is the largest pulsed gamma X-ray source in the world. The accelerator is made up of 20 inductive cavities that are charged to 1 MV each by complex pulsed power circuitry. The firing time of the machine components ranges between the microsecond and nanosecond timescales. This results in a variety of electromagnetic frequencies when the accelerator fires. Testing was done to identify the HERMES electromagnetic noise signal and to map it to the various accelerator trigger events. This report will show the measurement methods used to capture the noise spectrum produced from the machine and correlate this noise signature with machine events.

  5. The HERMES recoil detector. Particle identification and determination of detector efficiency of the scintillating fiber tracker

    HERMES is a fixed target experiment using the HERA 27.6 GeV polarized electron/positron beams. With the polarized beams and its gas targets, which can be highly polarized, HERMES is dedicated to study the nucleon spin structure. One of its current physics programs is to measure deeply virtual Compton scattering (DVCS). In order to detect the recoiling proton the Recoil Detector was installed in the target region in the winter of 2005, taking data until the HERA-shutdown in the summer of 2007. The Recoil Detector measured energy loss of the traversing particles with its sub-detectors, including the silicon strip detector and the scintillating fiber tracker. This enables particle identification for protons and pions. In this work a systematic particle identification procedure is developed, whose performance is quantified. Another aspect of this work is the determination of the detector efficiency of the scintillating fiber tracker. (orig.)

  6. Latest HERMES results on transverse spin effects in hadron structure and formation

    2008-01-01

    Transverse target single-spin asymmetries in semi-inclusive deep inelastic scattering allow to study the so-called Collins and Sivers mechanisms. The first one connects the poorly known fundamental transversity distribution function, describing the transverse spin-polarization of quarks in a transversely polarized proton, to the Collins fragmentation function, describing spin-orbit correlations in the hadron formation process. The second one is sensitive to the Sivers function, which correlates the intrinsic transverse momentum of quarks with the proton's spin orientation and is related to the orbital angular momentum of quarks. Preliminary results on azimuthal single target-spin asymmetries in semi-inclusive electro-production of pions and kaons at the HERMES experiment are presented. The full data set collected with a transversely polarized hydrogen target was analyzed providing the HERMES most precise results on the Collins and Sivers azimuthal moments. (orig.)

    It has previously been shown that the HERMES method ('Hadamard Encoding and Reconstruction of MEGA-Edited Spectroscopy') can be used to simultaneously edit pairs of metabolites (such as N-acetyl-aspartate (NAA) and N-acetyl aspartyl glutamate (NAAG), or glutathione and GABA). In this study, HERMES is extended for the simultaneous editing of three overlapping signals, and illustrated for the example of NAA, NAAG and Aspartate (Asp). Density-matrix simulations were performed in order to optimize the HERMES sequence. The method was tested in NAA and Asp phantoms, and applied to the centrum semiovale of the nine healthy control subjects that were scanned at 3T. Both simulations and phantom experiments showed similar metabolite multiplet patterns with good segregation of all three metabolites. In vivo measurements show consistent relative signal intensities and multiplet patterns with concentrations in agreement with literature values. Simulations indicate co-editing of glutathione, glutamine, and glutamate, but their signals do not significantly overlap with the detected aspartyl resonances. This study demonstrates that a four-step Hadamard-encoded editing scheme can be used to simultaneously edit three otherwise overlapping metabolites, and can measure NAA, NAAG, and Asp in vivo in the brain at 3T with minimal crosstalk.

  10. History of HERMES III diode to z-pinch breakthrough and beyond :

    2013-04-01

    HERMES III and Z are two flagship accelerators of Sandias pulsed-power program developed to generate intense -ray fields for the study of nuclear radiation effects, and to explore high energy-density physics (including the production of intense x-ray fields for Inertia Confinement Fusion [ICF]), respectively. A diode at the exit of HERMES III converts its 20-MeV electron beam into -rays. In contrast, at the center of Z, a z-pinch is used to convert its 20-MA current into an intense burst of x-rays. Here the history of how the HERMES III diode emerged from theoretical considerations to actual hardware is discussed. Next, the reverse process of how the experimental discovery of wire-array stabilization in a z-pinch, led to a better theory of wirearray implosions and its application to one of the ICF concepts on Z--the DH (Dynamic Hohlraum) is reviewed. Lastly, the report concludes with how the unexpected axial radiation asymmetry measured in the DH is understood. The first discussion illustrates the evolution of physics from theory-to-observationto- refinement. The second two illustrate the reverse process of observationto- theory-to refinement. The histories are discussed through the vehicle of my research at Sandia, illustrating the unique environment Sandia provides for personal growth and development into a scientific leader.

Robert Oppenheimer, the scientific director of the Manhattan Project, the single most recognizable face of the atomic bomb, and a man whose name has become almost synonymous with Cold War American nuclear science, was and still is a conflicted, controversial figure who has come to represent an equally ambivalent technology.

The data, from which SDMEs are determined, were accumulated with the HERMES forward spectrometer during the running period of 1996 to 2007 using the 27.6 GeV electron or positron beam of HERA. A sizable contribution of unnatural parity exchange amplitudes is found for exclusive ω meson production.

  4. Exclusive {rho}{sup 0} production measured with the HERMES recoil detector

    Perez Benito, Roberto Francisco

    2010-12-15

    The Hermes experiment (HERa MEasurement of Spin) at Desy was designed to study the spin structure of the nucleon in semi-inclusive deep inelastic scattering. The internal structure of the nucleon has been investigated in detail and it has been measured that the intrinsic quark spin contribution is only about 30% of the total spin of the nucleon. A formalism to describe the internal structure of the nucleon called Generalised Patron Distributions (GPDs) was developed recently to understand the fundamental structure of the nucleon. These GPDs can be accessed by the measurement of hard exclusive reactions and hard exclusive processes that can be understood in terms of GPDs. The accumulated Hermes data offer access to GPDs in different combinations of beam charge and beam and target helicity asymmetries. To improve exclusivity and to enhance the resolution of kinematic variables to study hard exclusive processes which provide access to the GPDs and hence to the orbital angular momentum of the quarks, in January 2006 a Recoil Detector was installed that surrounded the internal gas target of the Hermes experiment. The Hermes Recoil Detector consisted of three components: a silicon strip detector inside the vacuum, a scintillating fiber tracker and the photon detector. All three detectors were located inside a solenoidal magnet which provided a 1T longitudinal magnetic field. The Recoil Detector improves the selection of exclusive events by a direct measurement of the momentum and track position of the recoiling particle as well as by rejecting non-exclusive background. This detector was an ideal novel tool to combine energy and position measurements for charged particles in a momentum range of 0.1 to 1.4 GeV/c. The Recoil Detector was fully commissioned and operating. Data was taken continuously until the final Hera shutdown in July of 2007. In this thesis we report on the performance of the Recoil Detector and more specifically about the scintillating fiber tracker

  5. Color and Contingency in Robert Boyle's Works.

    Baker, Tawrin

    2015-01-01

    This essay investigates the relationship between color and contingency in Robert Boyle's Experiments and Considerations Touching Colours (1664) and his essays on the unsuccessfulness of experiments in Certain Physiological Essays (1661). In these two works Boyle wrestles with a difficult practical and philosophical problem with experiments, which he calls the problem of contingency. In Touching Colours, the problem of contingency is magnified by the much-debated issue of whether color had any deep epistemic importance. His limited theoretical principle guiding him in Touching Colours, that color is but modified light, further exacerbated the problem. Rather than theory, Boyle often relied on craftsmen, whose mastery of color phenomena was, Boyle mentions, brought about by economic forces, to determine when colors were indicators of important 'inward' properties of substances, and thus to secure a solid foundation for his experimental history of color.

    The Wood's lamp aids in the diagnosis of multiple infectious, inflammatory and neoplastic dermatologic conditions. Although the Wood's lamp has many applications, which have improved both the diagnosis and management of disease, the man credited for its invention is relatively unknown in medicine. Robert Williams Wood, a prominent physicist of the early 20th century, is credited for the invention of the Wood's lamp. Wood was the father of infrared and ultraviolet photography and made significant contributions to other areas in optics and spectroscopy. Wood's work encompassed the formative years of American Physics; he published over 200 original papers over his lifetime. A few years after the invention of the Wood's lamp for ultraviolet photography, physicians in Europe adopted the Wood's lamp for dermatologic applications. Wood's lamp remains popular in clinics globally, given its ease of use and ability to improve diagnostic precision. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Robert Oppenheimer has become the symbol of the scientist tormented and anguished by the consequences of his discoveries. R.Oppenheimer took a major part in the Manhattan project for the designing of the first atomic bomb. During this period he considered the thermonuclear bomb as the next step to reach but after Japan's surrender he reconsidered his position and favoured a more moderate atomic policy. R.Oppenheimer began to militate in favour of an international control of nuclear energy and wanted that Usa relinquish to design the hydrogen bomb. In 1953 in full Mac-Carthysm era, he was accused of being a communist and of spying for Ussr and as a consequence he was deprived of his office in AEC (atomic energy committee) but in 1963 president Lyndon Johnson rehabilitated him and R.Oppenheimer was awarded the highest reward of AEC: the Enrico Fermi prize.

    Deeply Virtual Compton Scattering (DVCS) i.e. ep {yields} ep{gamma} is the simplest interaction that allows access to Generalised Parton Distributions (GPDs), a theoretical framework describing nucleon structure. The strong interest in GPDs results from the fact that they can be used to determine the total angular momentum of quarks inside the nucleon and provide a 3-dimensional picture of nucleon structure. The measurement of the DVCS process is facilitated by the interference with a competing interaction known as the Bethe-Heitler process which has the same nal state. DVCS information is obtained from the asymmetrical in distribution of the real photon around the azimuthal angle {phi} at HERMES. Beam charge and beam helicity asymmetries, extracted from DVCS events with an unpolarised hydrogen target recorded during the 2006-2007 and 1996-2007 data taking periods, are presented in this thesis. The asymmetry amplitudes are presented over the range of HERMES kinematic acceptance, with their dependence on kinematic variables t, x{sub B} and Q{sup 2} also shown and compared to a phenomenological model.

    As part of a study on a two-phase natural circulation flow between the outer reactor vessel and the insulation material in the reactor cavity under an external reactor vessel cooling of APR1400, a HERMES-HALF experiment has been analyzed to verify and evaluate the experimental results using the RELAP5/MOD3 computer code. The RELAP5/MOD3 results have shown that the water circulation mass flow rate is very similar to the experimental results of the HERMES-HALF, in general. Increases in the water inlet area and the water level in the reactor cavity lead to an increase in the water circulation mass flow rate. In the small water inlet area condition, the lower value of the water outlet area has an effect on the water circulation mass flow rate, but the larger value of this has no effect. The air injection mass flow rate has no effect on the water circulation mass flow rate when it is greater than 40 % at the small water inlet area condition. However, an increase in the air injection mass flow rate leads to an increase in the water circulation mass flow rate. In the large water inlet area condition, increases in the water outlet area and the air injection mass flow rate lead to an increase in the water circulation mass flow rate. As the water outlet moves to a lower position, the water circulation mass flow rate slowly increases.

  11. The HERMES recoil photon detector and the study of deeply virtual Compton scattering

    2011-03-15

    The study of deeply virtual Compton scattering (DVCS) gives information about the contribution of the quark orbital angular momentum to the spin of the proton. DVCS has been studied at the HERMES experiment at DESY in Hamburg. Here 27.6 GeV longitudinally polarized electrons and positrons were scattered off a gaseous proton target. For the analysis of DVCS the recoiling proton could not be detected, but was reconstructed via its missing mass. This method suffers, however, from a 14% background contribution, mainly originating from associated DVCS. In this process the proton does not stay in its ground state but is excited to a {delta}{sup +} resonance. In order to reduce the background contribution down to less than 1%, a recoil detector was installed in the HERMES experiment beginning of 2006. This detector consists of three subcomponents, of which one is the photon detector. The main function of the photon detector is the detection of {delta}{sup +} decay photons. The photon detector was started up and commissioned for the analysis of (associated) DVCS. Subsequently DVCS and associated DVCS were analyzed using the recoil detector. (orig.)

  12. Analysis of hard exclusive scattering processes of the HERMES recoil experiment

    Deeply virtual Compton Scattering (DVCS), ep → epγ is the simplest reaction giving indication of generalized parton distributions (GPD) of the nucleon. The DVCS process has the same final state as the Bethe-Heitler process (BH). For this reason the access is taken not through the cross-sections directly but through asymmetries between DVCS events depending on charge and polarization of the 27.6 GeV beam. For the first time the azimuthal asymmetry amplitudes according the charge of the lepton beam are extracted using a kinematically complete reconstruction method at the HERMES experiment. The recoil detector installed in 2006 allows the reconstruction of recoiling protons that completes the measurements of the forward detector to cover almost the complete angle range around the vertex. This approach allows suppressing the background processes by almost a complete magnitude compared to the traditional method using only the information of the forward spectrometer. The analysis of the asymmetries was carried out at different values of the kinematic variables t c' x B and Q 2 to investigate the dependence of these variables. This work pushes the limits of the readability of data and shows which periods have been found to be unstable in the data acquisition. It points out the impact of this finding to previous HERMES publications.

    Robert H. Koch, emeritus professor of astronomy and astrophysics at the University of Pennsylvania, passed away at his home in Ardmore, Pennsylvania on 11 October 2010 after a brief illness. Bob was 80 years old and remained sharp and intellectually engaged with the astronomical community up until the onset of complications from a brain tumor. Bob was born in York, Pennsylvania on 19 December 1929, and graduated from York Catholic High School in 1947. He attended the University of Pennsylvania on a senatorial scholarship, graduating in 1951. After two years in the United States Army, he enrolled in graduate school at the University of Pennsylvania, doing his doctoral research on the photoelectric photometry of R CMa, AO Cas, AS Eri, and XY Leo at the Steward Observatory, University of Arizona in Tucson. Bob would continue this exploration of close binary stars, their atmospheres and interactions, for the rest of his career. Bob met his future spouse, Joanne C. Underwood, while in graduate school in 1957 and they were married in 1959. Bob received his PhD in astronomy in 1959 and moved to Amherst, Massachusetts, where he taught as a member of the Four College Astronomy Department until 1966. Following a year at the University of New Mexico in Albuquerque, Bob joined the Astronomy Department at Penn, teaching and doing research there until his retirement in 1996. Bob's main interests were the study of close and eclipsing binary stars, stellar envelopes and winds, intrinsic variables, transits and occultations, and the Milky Way Galaxy, producing well over 100 refereed publications. Bob was partial to photoelectric photometry and polarimetry, conducting most of his observational research at the University of Pennsylvania Flower and Cook Observatory, and at other ground- and space-based observatories. As an international figure in the area of binary stars, Bob had widespread collaborations with scientists at other institutions, in the US and throughout the world, and

    Full Text Available Resumen Los discursos cruzados son el soporte común del presente número de Cuadernos. El cruce que planteamos tiene como protagonistas al artista Robert Smithson y a los arquitectos Adam Caruso y Peter St John. Estos últimos hacen mención del trabajo del artista norteamericano para explicar su proyecto de remodelación de Stortorget, la plaza de la catedral en el centro de Kalmar, Suecia. A partir de aquí, comenzamos una exploración del trabajo y las preocupaciones de ambos que nos permite dibujar convergencias y sintonías procesuales por encima de las diferencias temáticas, ideológicas y estilísticas. Al disponer en paralelo la obra de Smithson y Caruso St John descubrimos vibraciones y resonancias que muestran una interacción productiva de sus preocupaciones. La materia se convierte en sus propuestas en un objeto activo y sensible, un depósito energético con el que operar. El traslado de piedras en Stortorget convoca la memoria de la ciudad del mismo modo que el basalto y la sal del Spiral Jetty, erosionados por el tiempo, nos hablan de procesos abiertos. El tiempo y la memoria pasan a ser soportes estratégicos con los que construyen sus miradas. Los objetos se disuelven en las relaciones que establecen con su entorno produciendo equilibrios frágiles e instantáneos. De esta manera el artículo pretende generar un vórtice de reflexión, una espiral en cuyo recorrido se manifiesten las tensiones parciales del cruce propuesto, sus fijezas momentáneas.

    Schoenherr, Neil T.

    2004-12-01

    Robert M. Walker, PhD, Professor of Physics in Arts & Sciences and a faculty fellow of the McDonnell Center for the Space Sciences, died of stomach cancer Thursday, 12 February 2004, in Brussels, Belgium. He was 75. Walker worked on the frontiers of space research for more than four decades. Robert Walker was born in Philadelphia on 6 February 1929. His mother was Dorothy Potter and he considered Roger Potter his father though he was not his biological father. His early years were spent in New York City and in upstate New York. He attended the Bronx High School of Science, earned his BS in physics from Union College and in 1954, he received his PhD in particle physics from Yale University. He subsequently joined the General Electric Laboratory in Schenectady, New York where he studied the radiation effects in solids. His work on defects in irradiated copper is still regarded as the definitive work on the topic. In the early 1960s, Walker's discovery of fossil nuclear particle tracks in minerals was instrumental to new developments in geo-chronology and cosmic ray physics. In particular, his discovery of tracks from nuclei heavier than iron opened a new frontier of cosmic ray physics. He subsequently pioneered the use of plastics to detect and count such nuclei in cosmic ray balloon flights. Beginning in 1966, when he moved to Washington University and became the first McDonnell Professor of Physics, his research interests turned more toward space physics. He was the inaugural director of the McDonnell Center, which was established in 1975 by a gift from aerospace pioneer James S. McDonnell. Walker was a member of the NASA committee that allocated samples of the first returned lunar materials, and his laboratory led the way in deciphering their record of lunar, solar system and galactic evolution. Together with Ghislaine Crozaz and other colleagues, Walker made path breaking laboratory studies of the first moon rocks revealing the history of solar radiation and

  20. Deflagration to Detonation Transition (DDT) Simulations of HMX Powder Using the HERMES Model

    2017-06-01

    We performed computer simulations of DDT experiments with Class I HMX powder using the HERMES model (High Explosive Response to MEchanical Stimulus) in ALE3D. Parameters for the model were fitted to the limited available mechanical property data of the low-density powder, and to the Shock to Detonation Transition (SDT) test results. The DDT tests were carried out in steel-capped polycarbonate tubes. This arrangement permits direct observation of the event using both flash X-ray radiography and high speed camera imaging, and provides a stringent test of the model. We found the calculated detonation transition to be qualitatively similar to experiment. Through simulation we also explored the effects of confinement strength, the HMX particle size distribution and porosity on the computed detonation transition location. This work was performed under the auspices of the US DOE by LLNL under Contract DE-AC52-07NA27344.

    2015-01-01

    Full Text Available Hermes collected a wealth of data using the 27.6 GeV polarized Hera lepton beam and various pure, polarized and unpolarized, gaseous targets. This unique data set opens the door to various measurements sensitive to the multi-dimensional structure of the nucleon. Among them are two-hadron production in semi-inclusive deep-inelastic scattering on a transversely polarized target, providing access to different transverse-momentum-dependent distribution and fragmentation functions in a way complementary to single-hadron production. Also transverse-target single-spin asymmetries in inclusive electroproduction of charged pions and kaons have been recently extracted, complementing data from proton-proton collisions, where large, so far unexplained, asymmetries have been observed. From inclusive measurements on various nuclear targets, the Λ polarization is extracted, also here complementing measurements in proton-proton collisions.

    The HERMES hydrogen and deuterium nuclear-polarized gas targets have been in use since 1996 with the polarized electron beam of HERA at DESY to study the spin structure of the nucleon. Polarized atoms from a Stern-Gerlach Atomic Beam Source are injected into a storage cell internal to the HERA electron ring. Atoms diffusing from the center of the storage cell into a side tube are analyzed to determine the atomic fraction and the atomic polarizations. The atoms have a nuclear polarization, the axis of which is defined by an external magnetic holding field. The holding field was longitudinal during 1996-2000, and was changed to transverse in 2001. The design of the target is described, the method for analyzing the target polarization is outlined, and the performance of the target in the various running periods is presented

    2016-12-01

    Full Text Available The study offers a Neoplatonic reading of certain iconographic elements of Domenico Ghirlandaio’s frescoes in the Tornabuoni Chapel in Florence. It focuses on the nude figure sitting on the steps in the “Presentation of the Virgin in the Temple” as well as the group of four listeners gathered on the right in the “Preaching of St. John the Baptist”. Following an investigation of the relationship between these figures and Marsilio Ficino’s philosophical ideas and the apocryphal gospels the author suggests that the nude represents Saturn and that the four men are Ficino’s famiglia filosofica: Hermes Trismegistus, Moses, Aristotle and Plato. This analysis therefore attempts to show that the decoration not only expresses the political supremacy of the Medicean faction but also conveys Ficino’s ideas about the prisca theologia.

  15. Transverse target moments of dihadron production in semi-inclusive deep inelastic scattering at HERMES

    Gliske, Stephen V.

    2011-09-15

    Pseudo-scalar meson production in semi-inclusive deep inelastic scattering (SIDIS) at HERMES has provided essential information towards the understanding of the transverse momentum dependent structure of the proton. SIDIS dihadron (hadron pair) production also provides access to the structure of the proton and is complimentary to that provided by pseudo-scalars production, as the same parton distribution functions are involved. For example, while pion and kaon final states allow access to flavor combinations of the Sivers distribution function, SIDIS {phi} meson production (included in the K{sup +}K{sup -} dihadron sample) allows direct access to the Sivers function for the strange quarks. The Sivers function for strange quarks is also related to the orbital angular momentum of the gluons. In the SIDIS cross section, the distribution functions are integrated with fragmentation functions for the respective final states. These fragmentation functions yield information regarding the quark hadronization process. Of particular interest, the Lund/Artru model of fragmentation makes specific predictions regarding the relation between results for dihadron and pseudo-scalar meson production for certain transverse momentum dependent moments. This dissertation presents the first transverse momentum dependent (non-collinear) analysis of the transverse target moments in SIDIS dihadron production, extracting results from the 2002-2005 HERMES data set for {pi}{sup +}{pi}{sup 0}, {pi}{sup +}{pi}{sup -}, {pi}{sup -}{pi}{sup 0} and K{sup +}K{sup -} dihadrons. A new transverse momentum dependent Monte Carlo generator, TMDGen, is also introduced. Additionally, several theoretical developments have been completed, including a new partial wave analysis of the fragmentation functions, computation of the next-to-leading twist dihadron cross section, and the first model calculation for transverse momentum dependent dihadron fragmentation functions.

    The analysis of the interdependence between time series has become an important field of research in the last years, mainly as a result of advances in the characterization of dynamical systems from the signals they produce, the introduction of concepts such as generalized and phase synchronization and the application of information theory to time series analysis. In neurophysiology, different analytical tools stemming from these concepts have added to the 'traditional' set of linear methods, which includes the cross-correlation and the coherency function in the time and frequency domain, respectively, or more elaborated tools such as Granger Causality.This increase in the number of approaches to tackle the existence of functional (FC) or effective connectivity (EC) between two (or among many) neural networks, along with the mathematical complexity of the corresponding time series analysis tools, makes it desirable to arrange them into a unified-easy-to-use software package. The goal is to allow neuroscientists, neurophysiologists and researchers from related fields to easily access and make use of these analysis methods from a single integrated toolbox.Here we present HERMES ( http://hermes.ctb.upm.es ), a toolbox for the Matlab® environment (The Mathworks, Inc), which is designed to study functional and effective brain connectivity from neurophysiological data such as multivariate EEG and/or MEG records. It includes also visualization tools and statistical methods to address the problem of multiple comparisons. We believe that this toolbox will be very helpful to all the researchers working in the emerging field of brain connectivity analysis.

  18. The construction of a high resolution crystal backscattering spectrometer HERMES I

    Energy Technology Data Exchange (ETDEWEB)

    Larese, J.Z.

    1998-11-01

    There is a need in the United States for a state-of-the-art, cold-neutron, crystal backscattering spectrometer (CBS) designed to investigate the structure and dynamics of condensed matter systems by the simultaneous utilization of long wavelength elastic diffraction and high-energy-resolution inelastic scattering. Cold neutron spectroscopy with CBS-type instruments has already made many important contributions to the study of atomic and molecular diffusion in biomaterials, polymers, semiconductors, liquid crystals, superionic conductors and the like. Such instruments have also been invaluable for ultra high resolution investigations of the low-lying quantum tunneling processes that provide direct insight into the dynamical response of solids at the lowest energies. Until relatively recently, however, all such instruments were located at steady-state reactors. This proposal describes HERMES I (High Energy Resolution Machines I) a CBS intended for installation at the LANSCE pulsed neutron facility of Los Alamos National Laboratory. As explained in detail in the main text, the authors propose to construct an updated, high-performance CBS which incorporates neutron techniques developed during the decade since IRIS was built, i.e., improved supermirror technology, a larger area crystal analyzer and high efficiency wire gas detectors. The instrument is designed in such a way as to be readily adaptable to future upgrades. HERMES I, they believe, will substantially expand the range and flexibility of neutron investigations in the United States and open new and potentially fruitful directions for condensed matter exploration. This document describes a implementation plan with a direct cost range between $4.5 to 5.6 M and scheduled duration of 39--45 months for identified alternatives.

    There is a need in the United States for a state-of-the-art, cold-neutron, crystal backscattering spectrometer (CBS) designed to investigate the structure and dynamics of condensed matter systems by the simultaneous utilization of long wavelength elastic diffraction and high-energy-resolution inelastic scattering. Cold neutron spectroscopy with CBS-type instruments has already made many important contributions to the study of atomic and molecular diffusion in biomaterials, polymers, semiconductors, liquid crystals, superionic conductors and the like. Such instruments have also been invaluable for ultra high resolution investigations of the low-lying quantum tunneling processes that provide direct insight into the dynamical response of solids at the lowest energies. Until relatively recently, however, all such instruments were located at steady-state reactors. This proposal describes HERMES I (High Energy Resolution Machines I) a CBS intended for installation at the LANSCE pulsed neutron facility of Los Alamos National Laboratory. As explained in detail in the main text, the authors propose to construct an updated, high-performance CBS which incorporates neutron techniques developed during the decade since IRIS was built, i.e., improved supermirror technology, a larger area crystal analyzer and high efficiency wire gas detectors. The instrument is designed in such a way as to be readily adaptable to future upgrades. HERMES I, they believe, will substantially expand the range and flexibility of neutron investigations in the United States and open new and potentially fruitful directions for condensed matter exploration. This document describes a implementation plan with a direct cost range between $4.5 to 5.6 M and scheduled duration of 39--45 months for identified alternatives

  20. [A history of Korean medical association's emblem: the caduceus of Asklepios and Hermes].

    An emblem represents the identity of an organization. Through the emblem of an organization, they differentiate the members from others and reinforce the membership, homogeneity, and pride. It is also a tool that an organization officially publicizes its mission and values. The symbol designed by Cho, Byungduk was announced as the first emblem of Korean Medical Association (KMA) on October 31st 1947. His design work has the caduceus with the Taeguk sign on the top, the symbol of Korea, and the Red Cross in the background including the name, 'KMA'. Since then, the emblem was revised three times: in 1964, 1973, and 1995. The current symbol is based on the design of the first one. Although Asklepian, the single serpent-entwined staff of Asklepios, is the one known as the symbol of medicine, this emblem takes the caduceus of Hermes who is the patron god of merchants, thieves, and travelers. The mistake comes from the unawareness of the distinction between the caduceus of Asklepios and Hermes. Moreover, it proves that U. S. Army Medical Corps (USAMC) heavily influenced the reconstruction of Korean health care system including KMA. The USAMC has used the symbol of caduceus since 1902. In 1947, the year that the first emblem of KMA was established, Southern part of Korea was governed by the United States Military Government (USMG, 1945-1948). The current emblem of KMA brings up a question whether we should continue to use the symbol that was taken from USMAC in the historical period of USMG governance. Celebrating 100th anniversary year of KMA, KMA needs to re-evaluate the appropriateness of the KMA symbol.

    SUMMARY This thesis Leaving Libertarianism: Social Ties in Robert Nozick s New Philosophy challenges the general and most widespread portrayals of the American philosopher Robert Nozick (1938-2002) by studying the notion of social ties in his later philosophy. The point of departure is the present descriptions of Nozick s philosophy. Mostly these depictions are based upon three postulates: That Nozick is an extreme individualist, that the libertarian Anarchy, State, and Utopia (1...

    Roberts-SC phocomelia syndrome comprises limb deficiencies of variable severity, facial clefts, and other anomalies. Tetra-amelia may also be associated with facial clefts and similar anomalies. We report on a female infant with severe tetra-amelia, micrognathia, cleft palate, splenogonadal fusion, and premature centromere separation. We propose that this represents the severe expression of the Roberts-SC phocomelia syndrome. 18 refs., 6 figs.

  5. Robert Lowell’s Culturally Coded Lexis

    Full Text Available In this paper, I will examine how a vital ele­ment of Robert Lowell’s descriptive and narrative struc­tures, i.e., the lexis, promise to unfold the “layers” of the culture that served as context for Life Studies. This in­volves exploring both the denotations and connotations of his culturally encoded lexis, that is, the external mean­ings of certain words and phrases before they “en­ter” the poem and the internal meanings they acquire after entering the poem. This process of “verbal osmo­sis”, when words absorb meaning from these different contexts, is, what I believe, critic and linguist Winifred Nowottny describes as “give and take between those patterns” (Fowler, 2009: 31. My analysis will focus on the sociolinguistic patina accrued on certain units of Lowell’s poetic lexis, such as names of historical people, events and concepts belonging to American and Euro­pean spiritual cultures and traditions, as well as brand names from popular material culture of the first half of the twentieth century. The analysis will also dwell on the use of idioms, catch phrases and other verbal clichés which reflect the culture that generated them. They func­tion as verbal “ready-mades” that additionally rein­force Lowell’s well-known anecdotal, colloquial and infor­mal poetic language. The choice of these particular lexical items is significant as they reflect the categoriza­tion of the world and the experience of the poetic voice or the “language user” in broader linguistic terms. At the same time, the categorization of the experience reflects the ideational position, the worldview of the language user. In the context of his poetics of immanence and experi­ence, this culturally coded poetic diction is ana­lyzed as another authentic and documented presenta­tion of immanent narrator’s “lived experience”.

    A definitive portrait of legendary scientist J. Robert Oppenheimer, the ''father'' of the atomic bomb, discusses his seminal role in the twentieth-century scientific world, as well as his lesser-known roles as family man, supposed communist, and head of Princeton's Institute for Advanced Studies. ''American Prometheus'' is a rich evocation of America in mid-century and a compelling portrait of scientist J. Robert Oppenheimer, a man shaped by its major events--the Depression, World War II, and the Cold War. (orig.) [German] J. Robert Oppenheimer (1904-1967), der ''Vater der Atombombe'', zaehlt zu den schillerndsten Figuren der juengeren Zeitgeschichte. Fuer ihre glaenzende Biographie des ''amerikanischen Prometheus'' erhielten der Journalist Kai Bird und der Historiker Martin J. Sherwin den Pulitzer-Preis. Exemplarisch lassen sie das Drama eines Forschers lebendig werden, der sich zwischen Erkenntnisdrang und ethischer Verantwortung entscheiden muss. Oppenheimer leitete das streng geheime Manhattan-Projekt in der Wueste von New Mexico, wo am 16. Juli 1945 die erste Atombombe gezuendet wurde. Kurz darauf starben in Hiroshima und Nagasaki mehr als 200 000 Menschen durch die neue ''Wunderwaffe'' - die Menschheit war ins Atomzeitalter eingetreten. Erschuettert von der Zerstoerungskraft seiner Schoepfung, engagierte sich Oppenheimer fortan gegen den Einsatz nuklearer Waffen. Das machte ihn im Amerika der McCarthy-Aera verdaechtig. Er geriet ins Visier des FBI, wurde als Spion der Sowjetunion verleumdet und musste den Staatsdienst quittieren. Sein Privatleben wurde an die Oeffentlichkeit gezerrt, seine Wohnung verwanzt, sein Telefon abgehoert. Erst 1963 rehabilitierte ihn Praesident Kennedy. Ueber dreissig Jahre hinweg haben die Autoren Interviews mit Oppenheimers Angehoerigen, Freunden und Kollegen gefuehrt, FBI-Akten gesichtet, Tonbaender von Reden und Verhoeren

    Robert Oppenheimer has become the symbol of the scientist tormented and anguished by the consequences of his discoveries. R.Oppenheimer took a major part in the Manhattan project for the designing of the first atomic bomb. During this period he considered the thermonuclear bomb as the next step to reach but after Japan's surrender he reconsidered his position and favoured a more moderate atomic policy. R.Oppenheimer began to militate in favour of an international control of nuclear energy and wanted that Usa relinquish to design the hydrogen bomb. In 1953 in full Mac-Carthysm era, he was accused of being a communist and of spying for Ussr and as a consequence he was deprived of his office in AEC (atomic energy committee) but in 1963 president Lyndon Johnson rehabilitated him and R.Oppenheimer was awarded the highest reward of AEC: the Enrico Fermi prize.

    Science.gov (United States)

    Surrounded by his loving family, Robert Charles Bless died at home on November 29th, three days before his 88th birthday. He was born in Ithaca, NY on Dec. 3, 1927 to a Russian father, Arthur Aaron Bless, and a French mother, Eva Chantrell Bless. Bob spent many summers on the family farm in the South of France, where he gained a great pride and joy in his French heritage, large extended family, and mother tongue. As a child growing up in Gainesville, FL, Bob's first job was snake wrangling, earning 10 cents per foot, with an added bonus for the more venomous species. Young Robbie took daily adventures in the Florida woods and swamps, armed only with pockets full of pecans and oranges. He enjoyed spending time at the family's lake cabin, where he learned to sail and helped his father plant acres of trees to grow their timber plantation. As a first generation immigrant, Bob's father received a PhD in physics, which inspired Bob to pursue an extensive educational route in astrophysics. Bob excelled in academics, graduating high school at the age of 16 and the University of Florida (B.Sc.) at 19. His path to graduate school was interrupted by a diagnosis of tuberculosis that forced him into a Florida sanitorium for one year. During this time, Bob made the most of what he described as the most dismal part of life by advocating for patient rights, initiating an inter-sanitorium newsletter, and gaining skills and experience in community organization and leadership - qualities that would later inform his leadership in academe. After being one of the first successfully treated tuberculosis patients in the US, Bob went on to earn a M.Sc. from Cornell University, and received his PhD degree in Astronomy from the University of Michigan in 1958. That same year, Bob joined the staff of the Astronomy Department of the University of Wisconsin (UW), Madison. It was there that Bob met Diane McQueen. Despite Bob's Dodge Dart and what has been described as the worst first date in

    Hermes is a member of the hAT transposon superfamily that has active representatives, including McClintock's archetypal Ac mobile genetic element, in many eukaryotic species. The crystal structure of the Hermes transposase-DNA complex reveals that Hermes forms an octameric ring organized as a tetramer of dimers. Although isolated dimers are active in vitro for all the chemical steps of transposition, only octamers are active in vivo. The octamer can provide not only multiple specific DNA-binding domains to recognize repeated subterminal sequences within the transposon ends, which are important for activity, but also multiple nonspecific DNA binding surfaces for target capture. The unusual assembly explains the basis of bipartite DNA recognition at hAT transposon ends, provides a rationale for transposon end asymmetry, and suggests how the avidity provided by multiple sites of interaction could allow a transposase to locate its transposon ends amidst a sea of chromosomal DNA.

    The cos {phi}{sub h} and cos 2{phi}{sub h} modulations of the spin independent semi-inclusive deep inelastic scattering cross section were measured at Hermes. These modulations are sensitive to the polarization and transverse motion of quarks within the nucleon. The Cahn effect, which contributes at subleading twist (twist-3) to cos {phi}{sub h} and twist-4 to cos 2{phi}{sub h}, is sensitive to transverse motion of quarks. The Boer-Mulders effect, which contributes at subleading twist to cos {phi}{sub h} and leading twist to cos 2{phi}{sub h}, requires non-zero transverse quark motion and is sensitive to quark polarization, effectively measuring the quark spin-orbit correlation. These modulations were measured in a fully differential way, as a function of x, y, z, and P{sub h} {sub perpendicular} {sub to} for positive and negative pions, kaons, and unidentified-hadrons produced from hydrogen and deuterium targets at Hermes. This is the the most complete measurement to date, for the first time granting access to the flavor dependent distribution and fragmentation functions that generate these moments. These measurement would not have been possible without an improved hadron-type identification algorithm for the Ring Imaging Cherenkov (RICH) detector. The EVT event-level algorithm is presented and now is the primary method used at Hermes. (orig.)

    The Transiting Exoplanet Survey Satellite (TESS) will provide high-precision time series photometry for millions of stars with at least a half-hour cadence. Of particular interest are the circular regions of 12° radius centred around the ecliptic poles that will be observed continuously for a full year. Spectroscopic stellar parameters are desirable to characterize and select suitable targets for TESS, whether they are focused on exploring exoplanets, stellar astrophysics or Galactic archaeology. Here, we present spectroscopic stellar parameters (Teff, log g, [Fe/H], v sin i, vmicro) for about 16 000 dwarf and subgiant stars in TESS' southern continuous viewing zone. For almost all the stars, we also present Bayesian estimates of stellar properties including distance, extinction, mass, radius and age using theoretical isochrones. Stellar surface gravity and radius are made available for an additional set of roughly 8500 red giants. All our target stars are in the range 10 using the High Efficiency and Resolution Multi-Element Spectrograph (HERMES; R ∼ 28 000) at the Anglo-Australian Telescope as part of the TESS-HERMES survey. Comparing our results with the TESS Input Catalogue (TIC) shows that the TIC is generally efficient in separating dwarfs and giants, but it has flagged more than 100 cool dwarfs (Teff < 4800 K) as giants, which ought to be high-priority targets for the exoplanet search. The catalogue can be accessed via http://www.physics.usyd.edu.au/tess-hermes/, or at Mikulski Archive for Space Telescopes (MAST).

    2009-01-01

    It is with great sadness that I report the passing of Peter Robert Wilson, a well-known and well-loved figure in the solar physics community. Peter was on the faculty of the Department of Applied Mathematics at the University of Sydney for 39 years, and Chair of the department for 24 of these years. He was the author or co-author of more than 80 scientific research papers and a book, Solar and Stellar Activity Cycles (1994), published by Cambridge University Press. He died suddenly of a heart attack, at his home in Glebe, Australia, in the early morning of 11 November 2007. Peter was an organizer of, and participant in, many international conferences and workshops. He traveled extensively, holding visiting appointments at the University of Colorado (JILA), at Cambridge University, at the College de France (Paris), and at the California Institute of Technology [CalTech]. Most of his work was in the field of solar physics, but he also did some work on the philosophy of science and on tides. Peter came from a line of mathematicians. His father, Robert Wilson, immigrated to Australia from Glasgow in 1911, and became a mathematics teacher at Scotch College, a private school in Melbourne. There his name was changed to 'Bill' because 'Bob' was already taken." Peter's enjoyment of this story as characteristic of Australian academia (as any fan of Monty Python would understand) is indicative of his infectious sense of humor. In a similar vein, he claimed ancestry traced back to the eighteenth-century Scottish mathematician Alexander Wilson, Professor of Astronomy at the University of Glasgow. That Wilson is famous in the solar physics community for his discovery, known as the "Wilson Effect," of the photospheric depressions associated with sunspots. Peter himself could not resist writing a paper on this subject, and was delighted when the bait was taken by some less-informed colleagues who chided him for "naming an effect after himself." "Bill" Wilson married Naomi

    2003-12-01

    Robert Fleischer was born 20 August 1918 to Leon and Rose Fleischer in Flushing, NY. He was educated at Harvard, receiving his BS in 1940, MA in 1947, and PhD in 1949. He specialized in geophysics and solar-terrestrial relations. Fleischer joined the faculty at Rensselaer Polytechnic Institute advancing from Assistant to Full professor in 1958. As Director of the RPI Observatory, Fleischer attempted to bring modern astronomy to the institutions in the Albany area by procuring the funds to build a radio telescope. He left for the National Science Foundation (NSF) before the observatory was completed. It is a testament to his character that without his enormous energy, organizational, and fundraising abilities, the radio telescope project languished after he left. Fleischer joined the NSF in 1962 as the Program Director for Solar-Terrestrial Research. He was the government-wide Coordinator for the International Quiet Sun Years, and coordinated the 1966 South American Eclipse expeditions. Thereafter, he was appointed Deputy Head of the Office of International Science Activities. Fleischer is most notably remembered as the head of the Astronomy Section at the National Science Foundation. He brought astronomy into its own at NSF and involved the community in a major way through use of advisory committees. He was dedicated to helping the astronomical community understand the funding system, the political environment, and the various factors in how money is allocated. Fleischer truly believed in the concept that scientists should be making the important decisions about their field. He was instrumental in injecting science into the oversight of the National Observatories. Relations with the community say a lot about the man, the complexities of his character, and the forces that drove him. Fleischer was passionate in his beliefs and in his devotion to doing the best for astronomy. His strong approach and belief in himself served him well in many ways, but caused him grief

  15. Roberts 22: a bipolar nebula with OH emission

    1980-01-01

    Roberts 22 is a bipolar reflection nebula illuminated by a hidden A2 Ie star. Most of its energy is radiated at infrared wavelengths. It also shows strong OH maser emission (OH 284.18 - 0.79) on the 1612 and 1665 MHz transitions, generally similar to the masers associated with M stars having infrared excesses. But the system contains no late-type star. This remarkable assemblage of attributes makes Roberts 22 unique; however, it is probably a key member of the newly-recognized population of bipolar nebulae. From an analysis of the properties of Roberts 22 some published interpretations of other bipolar nebulae are questioned, in particular the derivation of spectral types for their underlying stars by the assumption of photo-ionization of the gas, and their evolutionary description as proto-planetary nebulae.

    Robert Bourassa's contributions to the hydroelectric development at James Bay were acknowledged with the inauguration of a park in the ex-prime minister's name. Phase 1 of the James Bay hydroelectric project constituted the world's biggest construction site, employing more than 180,000 people from beginning to project completion. The James Bay project allowed Hydro-Quebec to gain one of the world's largest electric power utilities and to gain significant competitive edge over its competitors. The Robert Bourassa Park contains a picnic area and a visitor interpretation centre which describes the history of the project. A sequence of 5 signposts summarize the contributions that Robert Bourassa made to the megaproject which cost over $20.6 billion. The complex consists of 65 turbines which produce 15,235 megawatts of electricity. 1 fig

  17. Double trisomy (48,XXX,+18) with features of Roberts syndrome

    We report an infant with double trisomy 48,XXX,+18, who also displayed features of Roberts syndrome. All previously published cases with similar double trisomy have presented with features of trisomy 18 syndrome. The chromosome analysis done at birth revealed the double trisomy; parental chromosomes were normal. The proband presented with microbrachycephaly, unilateral cleft lip and palate, choanal atresia, midfacial capillary hemanioma, thin nares, shallow orbits, malformed ears, sparse hair, hypomelia of the upper limbs, rocker-bottom feet, auricular septal defect and agenesis of the corpus callosum. Characteristic features of Roberts syndrome included hypomelia, midfacial defects, and severe growth deficiency. Among the many different features reported in the literature for patients with trisomy 18 syndrome, the most consistent were growth deficiency, clenched fingers and congenital heart defects (e.g. VSD, ASD, PDA). Although some of our patient`s features such as cleft lip and cleft palate, low-set malformed ears, ASD, defects of the corpus callosum, choanal atresia, radial aplasia could also be seen in trisomy 18 syndrome (in 10-50% of the cases), her phenotype was more typical of Roberts syndrome because of symmetrical hypomelia and midfacial defects. Our patient`s chromosomes did not show premature separation of centromeric heterochromatin, a feature reported to occur in approximately one-half of individuals with Roberts syndrome. Sporadic aneuploidy involving different chromosomes has been found in lymphocyte cultures from some Roberts syndrome patients and is considered by some authors as a mitotic mutant. This aneuploidy is most likely to be chromosome gain. The simultaneous occurrence of trisomy X and 18 is extremely rare with only 11 cases having been reported in the literature. Our patient is unique since she has the double trisomy in addition to the characteristic features of Roberts syndrome.

    Few astronomy communication projects are as well known or as widely disseminated as the Astronomy Picture of the Day (or APOD for short). Since its creation in 1995, it has popularised thousands of images and helped to explain the cosmos through informative captions. Impressively, the site shows no signs of slowing down and has amassed many loyal supporters. This success can be attributed to the two astronomers behind the project: Robert Nemiroff and Jerry Bonnell. CAPjournal has interviewed Robert to discover his view of APOD, and the lesser known issues that surround it.

  19. Deeply Virtual Compton Scattering off a deuterium target at the HERMES experiment

    International Nuclear Information System (INIS)

    Movsisyan, Aram

    2011-05-01

    Deeply virtual Compton scattering is studied in this report, using all data collected at the HERMES experiment from 1996 to 2005. Azimuthal asymmetries with respect to beam-helicity, beam-charge and target polarization alone and also to their different combinations for hard exclusive electroproduction of real photons in deep-inelastic scattering from a both unpolarized and longitudinally polarized deuterium targets are measured. The asymmetries are attributed to the interference between the deeply virtual Compton scattering and Bethe-Heitler processes. The asymmetries are observed in the exclusive region -(1.5) 2 GeV 2 2 X 2 GeV 2 of the squared missing mass. The dependences of these asymmetries on -t, x N , or Q 2 are investigated. The results include the coherent process ed→edγ and the incoherent process ed→epnγ where in addition a nucleon may be excited to a resonance. For an unpolarized deuterium target, the leading Fourier amplitude of the beam-helicity asymmetry that is sensitive to the interference term is found to be substantial, but no significant t dependence is observed. The leading amplitude of the beam-charge asymmetry is substantial at large -t, but becomes small at small values of -t. The amplitudes of the beam-helicity asymmetry that are sensitive to the squared DVCS term are found to be consistent with zero. The deuteron Compton form factor H 1 appears to have a similar behavior as H of the proton. (orig.)

  20. Signals for transversity and transverse-momentum-dependent quark distribution functions studied at the HERMES experiment

    2010-08-15

    Intention of the present thesis was the study of transverse-momentum dependent quark distribution functions. In the focus stood the Fourier analysis of azimutal single-spin asymmetries of pions and charged kaons performed within the HERMES experiment. These asymmetries were reconstructed from deep-inelastic scattering events on a transversely polarized proton target and decomposed in Fourier components. In the framework of quantum chromodynamics such components can be interpreted as folding of quark distribution and fragmentation functions. By the analysis of the transverse-momentum dependent quark distribution functions the study of spin-orbit correlations in the internal of the nucleon was made possible. By this conclusions on the orbital angular momentum of the quarks can be drawn. The extracted Fourier components extend the hitherto available informations on the transverse-momentum dependent quark distribution functions remarkably. The presented Fourier analysis made not only a detection of the Collins and Sivers effects possible, but beyond the extraction of the signals of the pretzelosity and worm-gear distributions. The so obtained results will conclusively contribute to the understanding of future measurements in this field and furthermore make possible a test of fundamental predictions of quantum chromodynamics.

    This thesis reports a new ''isoscalar'' measurement of {delta}s + {delta} anti s. Because strange quarks carry no isospin, the strange seas in the proton and neutron are identical. In the deuteron, an isoscalar target, the fragmentation process in DIS can be described without any assumptions regarding isospin dependent fragmentation. In the isoscalar extraction of {delta}s + {delta} anti s only the spin asymmetry for K{sup 0}{sub s} A{sup K{sup 0}{sub s1,d}} (x,Q{sup 2}, z) and the inclusive asymmetry A{sub 1,d}(x,Q{sup 2}) are used. An accurate measurement of the total non-strange quark polarisation {delta}Q = {delta}u + {delta} anti u + {delta}d + {delta} anti d comes directly from A{sub 1,d}(x,Q{sup 2}). The fragmentation functions needed for a leading order (LO) extraction of {delta}S = {delta}s + {delta} anti s are measured directly at HERMES kinematics using the same data. As a result of this analysis, the helicity densities for the strange quarks are consistent with zero with the experimental uncertainty over the measured x kinematic range. (orig.)

    Operative clinical trials are often small and open-label. Randomization is therefore very important. Stratification and minimization are two randomization options in such trials. The first aim of this study was to compare stratification and minimization in terms of predictability and balance in order to help investigators choose the most appropriate allocation method. Our second aim was to evaluate the influence of various parameters on the performance of these techniques. The created software generated patients according to chosen trial parameters (e.g., number of important prognostic factors, number of operators or centers, etc.) and computed predictability and balance indicators for several stratification and minimization methods over a given number of simulations. Block size and proportion of random allocations could be chosen. A reference trial was chosen (50 patients, 1 prognostic factor, and 2 operators) and eight other trials derived from this reference trial were modeled. Predictability and balance indicators were calculated from 10,000 simulations per trial. Minimization performed better with complex trials (e.g., smaller sample size, increasing number of prognostic factors, and operators); stratification imbalance increased when the number of strata increased. An inverse correlation between imbalance and predictability was observed. A compromise between predictability and imbalance still has to be found by the investigator but our software (HERMES) gives concrete reasons for choosing between stratification and minimization; it can be downloaded free of charge. This software will help investigators choose the appropriate randomization method in future two-arm trials.

    The first experiment of ring image Cherenkov detector (RICH) used aerogel in the world was reported in this paper. We built RICH using aerogel as illuminant for HERMES. The refractive index and size of all aerogel tiles were measured in order to select them for construction of RICH. The select conditions of tile were 113.1 -4 , the dispersion of refractive index of aerogel tile, which condition was fitted to the accuracy of Cherenkov light emission angle of RICH. The mean thickness, transmission and reflection of tile, the thickness of corner of tile (thickness of surface), the refractive index dependence on position and temperature were measured. The effect of thickness of tile on the shift of Cherenkov emission angle was 6.1% the maximum value per one tile and 0.18% mean value of center. The effect of position dependence of refractive index on the Cherenkov light emission angle was agreed with the effect of dispersion of thickness of tile. The transmission and reflection of tile were almost same as the theoretical value. (S.Y.)

    2009-11-15

    The experiments at the HERA storage ring at DESY yielded a large contribution to the understanding of the nucleon structure. They used for this the deep inelastic scattering (DIS) in the collision of electrons/positrons and protons. The HERMES experiment at DESY applied the longitudinally polarized electron or positron beam with an energy of 27.6 GeV together with a polarized or unpolarized gas target in order to study the spin structure of the nucleon. By the measurement of deeply virtual Compton scattering (DVCS) the generalized parton distributions (GPDs) can be determined. These allow a unified description of the nucleon structure. Furthermore they give an experimental approach to the orbital angular momenta of the quarks. However the DVCS process is not discriminable from the Bethe-Heitler (BH) process, in which the scattered electron produces by bremsstrahlung processes a real photon. But it was proved that the interference caused by this indiscriminability of BH and DVCS presents the approach to the DVCS amplitude. This pursues by the measurement of asymmetries of the BH-DVCS cross section in relation to the beam charge, the beam polarization, or the target polarization. The HERMES spectrometer was constructed in order to measure semi-inclusive and inclusive DIS processes. The extraction of the azimutal asymmetries in relation to the beam helicity from the data of 2007 at the hydrogen target were performed in this thesis. The extracted asymmetry amplitudes from the elastic BH/DVCS process agree well with the earlier measurements of HERMES. Furthermore for the first time the asymmetry of {delta}{sup +} resonances was extracted, however the events are because of the low statistics affect with large uncertainties.

    Highlights: Black-Right-Pointing-Pointer Cd accumulated in stem bottom part exceeded the defined hyperaccumulator threshold. Black-Right-Pointing-Pointer No toxic symptoms occurred and TI of all growth parameters ranged between 0.7 and 1. Black-Right-Pointing-Pointer The high level of Zn, Mn and Cu may contribute to the absence of chlorosis in stem. Black-Right-Pointing-Pointer Cd/Ca synergistic effect observed in the stem may alleviate Cd toxicity. Black-Right-Pointing-Pointer Hermes variety accumulated more Cd than the other flax varieties ever described. - Abstract: The potential of mature flax plants (cv. Hermes) to tolerate and accumulate cadmium (Cd) was studied to determine which part of the plant would be the key organ for phytoremediation purposes. After 4 month-growth on sand substrate containing 0.1 mM Cd in a greenhouse, the roots and stems were separated and the stems were divided into three parts. The effects of Cd were studied on growth parameters, histology and mineral nutrition. No visible toxic symptoms were observed. Tolerance-index values calculated from growth parameters and nutrients remained relatively high, allowing the development of the plant until maturity and formation of seeds. The roots and bottom stem accumulated the highest quantity of Cd (750 and 360 mg/kg dry matter), values which largely exceeded the threshold defined for hyperaccumulators. On the other hand, basal stem had a high bioconcentration factor (BCF = 32) and translocation factor TF Prime (2.5) but a low TF (0.5), indicating that this basal part would play a major role in phytoremediation (phytostabilization rather than phytorextraction). Therefore, the high tolerance to Cd and accumulation capacity make possible to grow Hermes flax on Cd-polluted soils.

    Deeply virtual Compton scattering is studied in this report, using all data collected at the HERMES experiment from 1996 to 2005. Azimuthal asymmetries with respect to beam-helicity, beam-charge and target polarization alone and also to their different combinations for hard exclusive electroproduction of real photons in deep-inelastic scattering from a both unpolarized and longitudinally polarized deuterium targets are measured. The asymmetries are attributed to the interference between the deeply virtual Compton scattering and Bethe-Heitler processes. The asymmetries are observed in the exclusive region -(1.5){sup 2} GeV{sup 2}

  5. Energy Tax versus Carbon Tax. A quantitative macro economical analysis with the HERMES/MIDAS models

    Karadeloglou, P.

    1992-01-01

    The idea of imposing a tax has been recently put forward as a policy-instrument to induce substitutions aiming at reducing CO[sub 2] overall emissions. One can distinguish two options: recycle tax revenues for energy system restructuring (supply or demand restructuring); or use the corresponding revenues in order to reduce the negative impacts caused on the economic activity by the introduction of the tax. Several papers dealing with only the macroeconomic aspects of the environmental problems have been written. These papers neglect more or less the energy sphere and consider that the energy feedback effects are very small. Macroeconomic impacts of the carbon tax have been examined for the United Kingdom and for the four big European countries elsewhere. In this paper a synthesis of both the energy and the macroeconomic approaches is realized. The approach adopted is global and tries to evaluate the impacts on both the economic and energy system. The main question examined is the effectiveness and impacts of fiscal policy on CO[sub 2] emission and the effects of the adoption of an accommodating policy. Thus, not only the effects of imposing an energy or carbon tax are examined, but also the effects of introducing accommodating measures are studied. The analysis is effected by using the HERMES-MIDAS linked system of models and is limited in analyzing the effects of carbon and energy taxes and the reduction of direct taxes and is effected for four countries namely France, Federal Republic of Germany, Italy and the United Kingdom. In section 2 policy scenarios are described while in sections three and four the results of the policy simulations are presented. In section five we compare the differences of two taxes (energy tax and carbon tax) and in section six the reduction of direct taxation as an accommodating measure is examined. 27 tabs., 10 refs

  6. Determination of the structure function F{sub 2} at HERMES

    Gabbert, Dominik D.

    2008-11-15

    In this thesis we present the first measurement of inclusive proton and deuteron deep-inelastic scattering cross sections at the HERMES experiment. The measurement is performed using the 27.6 GeV lepton beam provided by the HERA storage ring in conjunction with hydrogen and deuterium gas targets internal to the beam pipe. The relevant systematic effects such as radiative corrections, detector smearing, acceptance, particle misidentification, misalignment, tracking related effects and trigger efficiencies are taken into account. Based on these results, the structure functions F{sup p}{sub 2} and F{sup d}{sub 2} are determined using the parameterization R{sub 1998} for the longitudinal-to-transverse virtual-photon absorption cross section R. A phenomenological fit of the proton deep-inelastic scattering cross section is performed based on all available data and using photoproduction data in order to pin down the low Q{sup 2} region. A second fit is performed to the world data on the deuteron-to-proton cross section ratio in order to study its Q{sup 2} evolution, the difference between higher twist contributions in proton and deuteron, and the difference between R as obtained from the two targets. It can be confirmed that R obtained for proton and deuteron is in agreement. The Gottfried integral is evaluated from the fit at different values of Q{sup 2}. The result at Q{sup 2}=4 GeV{sup 2} agrees with previous measurements by NMC and no indication for a Q{sup 2} dependence of the Gottfried integral is found. (orig.)

  10. Transitioning Natures: Robert Schuller’s Garden Grove Experiment

    2016-09-01

    Full Text Available Through the lens of Evangelist Reverend Robert H. Schuller’s Garden Grove drive-in walk-in church, this paper aims to exemplify how his architecture has transcended existing geographies that have long been anchored by the epistemology of what can be referred to as traditional “religious” architecture. This paper examines how Schuller instrumentalized broader imbrications of political contexts to change or manipulate the traditional religious subject. It also presents how Robert Schuller’s Garden Grove experiment reconceptualized “territory” as an evolving ideological dimension; not as a trajectory, or as transitory space, but as inhabitable third nature. My analysis challenges established readings of religious architecture as being interiorized manifestations. To do so, it poses the following questions: how does this meta-geographical dimension shed new light on questions of (traditional architectural aesthetics in Protestant architecture? What spaces and politics does it produce? Does the third nature have a history of its own?

  14. The auriferous placer at Mount Robert, Pietersburg Greenstone belt

    1986-01-01

    The Mount Robert gold placer near Potgietersrus occurs in coarse, matrix-supported conglomerates of the Uitkyk Formation within the Pietersburg greenstone belt. Sedimentological and mineralogical investigations indicate that the conglomerates and the ore minerals were derived from a greenstone provenance, and that they were deposited in a braided river environment within a rapidly subsiding trough. Lack of sedimentological concentration of the heavy minerals is considered to be the main reason for the low and erratic gold grades encountered (usually below 1 g/t) and, thus, the failure of all past mining ventures. The mineralogical composition of the Mount Robert ore closely resembles that of the Witwatersrand deposits. However, uraninite is absent, probably as a result of its complete removal by weathering processes. Remaining small uranium concentrations can still be detected within the conglomerates where they occur associated with grains of carbonaceous matter, leucoxene aggregates, and secondary iron-hydroxides. U3O8 values found in the conglomerates are given

The drawings show that both Hooke and Waller were proficient draftsmen with a keen eye for the details of petrified objects. These drawings provided Hooke with a polemic edge in making the case for the organic origins of ‘figured stones’.

    Roberts syndrome and SC phocomelia syndrome are rare autosomal recessive genetic disorders representing the extremes of the spectrum of severity of the same condition, caused by mutations in ESCO2 gene. We report three new patients with Roberts syndrome from three unrelated consanguineous Egyptian families. All patients presented with growth retardation, mesomelic shortening of the limbs more in the upper than in the lower limbs and microcephaly. Patients were subjected to clinical, cytogenetic and radiologic examinations. Cytogenetic analysis showed the characteristic premature separation of centromeres and puffing of heterochromatic regions. Further, sequencing of the ESCO2 gene identified a novel mutation c.244_245dupCT (p.T83Pfs*20) in one family besides two previously reported mutations c.760_761insA (p.T254Nfs*27) and c.764_765delTT (p.F255Cfs*25). All mutations were in homozygous state, in exon 3. The severity of the mesomelic shortening of the limbs and craniofacial anomalies showed variability among patients. Interestingly, patient 1 had abnormal skin hypopigmentation. Serial fetal ultrasound examinations and measurements of long bones diagnosed two affected fetuses in two of the studied families. A literature review and case comparison was performed. In conclusion, we report a novel ESCO2 mutation and expand the clinical spectrum of Roberts syndrome. © 2015 Japanese Teratology Society.

    We present an Echelle+CCD, high signal-to-noise ratio, high-resolution (R = 20,000) spectroscopic atlas of 108 well-known objects representative of the most common types of peculiar and variable stars. The wavelength interval extends from 4600 to 9400 A and includes the RAVE, Gaia, and HERMES wavelength ranges. Multi-epoch spectra are provided for the majority of the observed stars. A total of 425 spectra of peculiar stars, which were collected during 56 observing nights between 1998 November and 2002 August, are presented. The spectra are given in FITS format and heliocentric wavelengths, with accurate subtraction of both the sky background and the scattered light. Auxiliary material useful for custom applications (telluric dividers, spectrophotometric stars, flat-field tracings) is also provided. The atlas aims to provide a homogeneous database of the spectral appearance of stellar peculiarities, a tool useful both for classification purposes and inter-comparison studies. It could also serve in the planning and development of automated classification algorithms designed for RAVE, Gaia, HERMES, and other large-scale spectral surveys. The spectrum of XX Oph is discussed in some detail as an example of the content of the present atlas.

  20. Fragmentation and nucleon structure in semi-inclusive deep-inelastic scattering at the HERMES experiment

    2013-10-15

    Multiplicities for the semi-inclusive production of each charge state of {pi}{sup {+-}} and K{sup {+-}} mesons in deep-inelastic scattering are presented as a function of the kinematic quantities x, Q{sup 2}, z and P{sub h} {sub perpendicular} {sub to}. The multiplicities were extracted from data collected by the HERMES experiment at the HERA storage ring using 27.6 GeV electron and positron beams on a hydrogen or deuterium gas target. These results for identified hadrons constitute the most precise measurement to date, and will significantly enhance our understanding of the proton structure, as well as the fragmentation process in deep-inelastic scattering. Furthermore, the 3D binning at an unprecedented level of precision provides a handle to help disentangle the transverse momentum structure of both. The high level of precision coupled with an intermediate energy regime requires a careful study of the complex interaction between the experimental systematics, theoretical uncertainties, and the applicability of the factorization theorem within the standard framework of leading-twist collinear QCD. This is illustrated by the extraction of the valence quark ratio d{sub {nu}}/u{sub {nu}} at leading-order in {alpha}{sub s}. These results show a strong z-dependence below z {approx} 0.30, which could be interpreted as evidence for factorization breaking. This evidence weakens somewhat when isospin invariance of the fragmentation functions is assumed to be broken. Additionally, the multiplicities for the semi-inclusive production of {pi}{sup 0} mesons in deep-inelastic scattering are presented as a function of z. These multiplicities were extracted from the same data sample as used for the charged meson results. The neutral pion multiplicity is the same as the average charged pion multiplicity, up to z {approx} 0.70. This is consistent with isospin invariance below z {approx} 0.70. The results at high values of z show strong signs of isospin symmetry breaking.

    This dissertation describes the measurement of two single-spin asymmetries (SSAs) in the production of particles from inelastic lepton-proton collisions. SSAs are a convenient observable for investigating the spin-dependent part of the electron-proton cross section. The analyzed data were taken by the HERMES experiment at DESY, using a 27.6 GeV electron/positron beam and a static hydrogen target in which the proton spin was polarized transversely to the direction of the beam. In the first case, SSAs were investigated in the inclusive electroproduction of charged pions and kaons. The asymmetries were studied as a function of the hadron momentum, p{sub T}, relative to the direction of the incident beam, and the Feynman variable x{sub F}. In the kinematic range 0.08 GeV

The analyzed data were taken by the HERMES experiment at DESY, using a 27.6 GeV electron/positron beam and a static hydrogen target in which the proton spin was polarized transversely to the direction of the beam. In the first case, SSAs were investigated in the inclusive electroproduction of charged pions and kaons. The asymmetries were studied as a function of the hadron momentum, p T , relative to the direction of the incident beam, and the Feynman variable x F . In the kinematic range 0.08 GeV T F T up to about 6% (8%) for pions (kaons) and then decrease again with increasing p T . For negative hadrons the asymmetries were of much smaller magnitude, sometimes positive and sometimes negative. When binned simultaneously in p T and x F , the asymmetries were found to be essentially independent of x F in each slice of p T . The analyzed data were manifestly dominated by hadrons from quasi-real photoproduction. In these reactions, the asymmetry can be related to the hadronic component of the photon and thus to the asymmetry A N observed in hadronic collisions at different energies but not yet fully understood. However, the largest contribution to the measured SSAs are from hadrons produced in deep-inelastic scattering (DIS) reactions, related to the Sivers function, which describes the asymmetric distribution of unpolarized quarks in a transversely polarized proton. Transverse SSAs were also measured in inclusive DIS, where only the scattered beam lepton is detected. In this case, non-zero SSAs would arise from two-photon exchange contributions to the electron-proton cross section. This observable is thus a check of the validity of the one-photon exchange approximation, commonly used in theoretical

    More than a university, Oral Roberts University in Tulsa, Oklahoma, was also the headquarters for evangelist Oral Roberts's electronic church. The electronic church in America, dominated by Christian evangelicals, used technology to spread the Gospel over radio airways and television signals to a dispersed audience. Yet evangelicals like Roberts also constructed ambitious campuses in real space and time. The architecture of Oral Roberts University visualized a modern and "populuxe" image for the electronic church in the 1960s and 1970s. The university's Prayer Tower purposely alluded to the Seattle Space Needle, aligning religion and the Space Age, and the campus's white, gold, and black color palette on late modern buildings created an image of aspirational luxury, conveying Roberts's health and wealth gospel. Oral Roberts University served as a sound stage for Roberts's radio and television shows, a pilgrimage point for his audience, and a university dedicated to training evangelicals in the electronic church.

    The 3 most important scientific achievements of N.Bohr follow. First, the Bohr-Rutherford atomic model in which Thomson's electrons, Rutherford's nucleus and Planck's quanta merged together to explain the line spectra of atoms. Secondly, the compound nucleus model in which Bohr explained nuclear reactions by the production of an intermediate state by the impact of an incident nucleus: the entering projectile would hit one or more nucleons, its energy and momentum being spread over them and after a while when one or more nucleons have acquired sufficient energy they escape from the compound nucleus. And thirdly, the drop model that presents the nucleus as behaving like a liquid, with modes of surface and volume oscillations of its own, ready to become excited isotopes by incoming neutrons.

    Theatre was among the first popular culture forms to address HIV/AIDS and did so memorably in such works as The Normal Heart, As Is, Love! Valor! Compassion!, and March of the Falsettos. As a response to criticisms of stage dramas focusing on HIV/AIDS in the main as undifferentiated and melodramatic, the author suggests critical consideration of two works by playwright Robert Chesley. In her analysis of Night Sweats and Jerker, the author argues Chesley offers an alternative perspective that is both liberatory and sex-positive.

And, in this case, rights and freedom protected under the philosophers state would obviously be violated. We also analyze the flaws in Nozicks model through economic bias in order to show - through game theory and logic of collective action  how an organization that provides nonexclusive public goods is vulnerable to the action of free-riders, thus increasing the costs of its performance, and decreasing motivation for its existence.

    Full Text Available L’herméneutique philosophique de Gadamer se présente comme une tentative de libérer la question de la vérité de l’étroitesse dans laquelle le concept moderne de méthode l’aurait cantonnée. Pour ce faire, elle interroge des expériences (l’art, l’histoire, le langage dont l’ampleur ne se laisse pas réduire au primat de la conscience certaine de soi. C’est pourquoi la critique de la méthode moderne qu’opère l’herméneutique en interrogeant l’expérience de la compréhension est en même temps une critique du fondement de cette méthode, c’est-à-dire de la subjectivité, de la conscience certaine de soi. L’objet de cette étude est de mettre en évidence la cohérence et l’unité de ce qui vient dans l’herméneutique se substituer, sous diverses figures apparemment éparses, au « sujet » : la question du « sujet » y devient celle du « sujet » comme question.Gadamer’s philosophical hermeneutics presents itselfs as an attempt to liberate the question of the truth in which the modern concept of method should have it confined. So Gadamer analyses experiences (art, history, language whose extent can’t be reduced to the primacy of selfconsciousness. So the critic of modern method by hermeneutics is at the same time the critic of its foundation, that is to say of the subjectivity, of the certainty of selfsconsciousness. The intention of this study is to bring foreward the coherence and the unity of Gadamer’s diverses remarks about what comes after subjectivity : the question of « subject » becomes the one of the « subject » as a question.

    2004-09-01

    Full Text Available In this article, we argue for the existence of a relationship between metanarrative and leadership effectiveness that is mediated by personal meaning. After analyzing the relevant literatures, we present a model that attributes this relationship to the capacity of metanarrative to produce meaning through the interpretive frames of Telos (teleological context, Chronos (historical-narrative context, and Hermēneia (interpretive context. We begin with a review of the leadership effectiveness literature followed by a discussion of the theoretical foundations of the concepts of meaning and metanarrative. From this review, we derive a set of propositions that describe the nature of the interrelationships among the constructs of interest and present a theoretical model that captures the proposed relationships. We conclude by suggesting several streams of research designed to evaluate the proposed model and with recommendations for further study.

    Full Text Available The accuracy of first pendulum gravity measurements in the Czech territory was determined using both original surveying notebooks of Robert Daublebsky von Sterneck and modern technologies. Since more accurate methods are used for gravity measurements nowadays, our work is mostly important from the historical point of view. In previous  works, the accuracy of Sterneck’s gravity measurements was determined using only a small dataset. Here we process all Sterneck’s measurements from the Czech territory (a dataset ten times larger than in the previous works, and we complexly assess the accuracy of these measurements. Locations of the measurements were found with the help of original notebooks. Gravity in the site was interpolated using actual gravity models. Finally, the accuracy of Sterneck’s measurements was evaluated as the difference between the measured and interpolated gravity.

    Robert Heath Lock (1879-1915), a Cambridge botanist associated with William Bateson and R. C. Punnett, published his book Recent Progress in the Study of Variation, Heredity, and Evolution in 1906. This was a remarkable textbook of genetics for one appearing so early in the Mendelian era. It covered not only Mendelism but evolution, natural selection, biometry, mutation, and cytology. It ran to five editions but was, despite its success, largely forgotten following Lock's early death in 1915. Nevertheless it was the book that inspired H. J. Muller to do genetics and was remembered by A. H. Sturtevant as the source of the earliest suggestion that linkage might be related to the exchange of parts between homologous chromosomes. Here we also put forward evidence that it had a major influence on the statistician and geneticist R. A. Fisher at the time he was a mathematics student at Cambridge.

    In 1665, Robert Hooke published his major work in microscopy, Micrographia, a defense of experimental philosophy. The following year, Margaret Cavendish, Duchess of Newcastle, published at her own expense a treatise and a novel that undermined the basis of this new science. The dispute broke out at the initiative of the Duchess, in the context of a vast controversy about the legitimacy and the efficiency of optical instruments in natural philosophy. All the figures of the dual are used, except one: the counterattack. Cavendish, indeed, was alone on the battlefield. Is it possible to call a dual a battle with only one combatant? This particular case of dispute that stops owing to the shortage of combatants is the subject of this article.

    2009-01-01

    In a provocative reassessment of one of the quintessential figures of early modern science, Rose-Mary Sargent explores Robert Boyle's philosophy of experiment, a central aspect of his life and work that became a model for mid- to late seventeenth-century natural philosophers and for many who followed them. Sargent examines the philosophical, legal, experimental, and religious traditions-among them English common law, alchemy, medicine, and Christianity-that played a part in shaping Boyle's experimental thought and practice. The roots of his philosophy in his early life and education, in his religious ideals, and in the work of his predecessors-particularly Bacon, Descartes, and Galileo-are fully explored, as are the possible influences of his social and intellectual circle. Drawing on the full range of Boyle's published works, as well as on his unpublished notebooks and manuscripts, Sargent shows how these diverse influences were transformed and incorporated into Boyle's views on and practice of experiment.

    Full Text Available The films of French director Robert Bresson are considered sober and transcendental. However, in A gentle woman (1969 and in Four nights of a dreamer (1972, he included extracts of quite different genres, like a libertine comedy (the extract of film Benjamim by Michel Deville, 1968, a Shakespearean tragedy (a performance of Shakespeare´s Hamlet and a gangster film (When love possesses us, produced by Bresson himself. In a way, those excerpts represent exactly the opposite of Bresson´s cinema. On the other hand, they still have some familiarity with it. We analyze the approach of those genres in the sequences in Bresson´s films, as well of the styles present in them by the use of music and images of paintings.

    The experimental philosopher Robert Hooke (1635-1703) is known to have apprenticed to the leading painter Peter Lely on his first arrival in London in the late 1640s. Yet the relevance of Hooke's artistic training to his mature draughtsmanship and identity has remained unclear. Shedding light on that larger interpretive problem, this article argues for the attribution to Hooke of a figural drawing now in Tate Britain (T10678). This attributed drawing is especially interesting because it depicts human subjects and bears Hooke's name functioning as an artistic signature, both highly unusual features for his draughtsmanship. From evidence of how this drawing was collected and physically placed alongside images by leading artists in the early eighteenth century, I suggest how it can offer new insight into the reception of Hooke and his graphic work in the early Enlightenment.

    2005-12-01

    Between 1875 and 1910 Sir Robert Stawell Ball gave an estimated 2,500 lectures in towns and cities all over the British Isles and abroad. This paper traces his lecturing career from its beginnings in Ireland to the triumphs of the Royal Institution, and on lecture tours in the United States of America. After a period in mathematics and mechanics, he became a populariser of science, especially astronomy, and found fame and fortune among the working classes and the aristocracy. What motivated him to tireless travels is uncertain, but it might have been that it was rewarding, financially and to his reputation. Whatever his motives, contemporary accounts are clear that BallÕs lectures were extremely popular and well-received.

    Full Text Available This article is a study of Robert Musil´s work “The Man Without Qualities” from philosophical sources. It is a novel that has produced so many overriding metaphors through which we can better understand the crises of the social identity on the horizont of the last modernity in Europe. Much of the key-concepts that helped in creating the so called “Leyend of Modernity” start to vanish in an irremediable way: not only did Musil trace the disappearance of the support for national aspirations and social cohesion, he also showed us how culture is a mad carrousel of collapsed expectations, and how the prevailing idea of “subjectivity” lacks today any solid or essential nucleus. In the middle of this disenchanted landscape of Europe, where all the modern and clasical illusions became nothing, appears however “a new human being”, since the man “without qualities” is the man with endless possibilities too.El presente ensayo es una interpretación de la novela de Robert Musil “El hombre sin atributos” a partir de fuentes filosóficas. Se trata de una obra que ha producido algunas metáforas decisivas para comprender las crisis de la identidad social en el horizonte de la última modernidad europea. Muchos de los conceptos clave que ayudaron a crear la leyenda de la modernidad empiezan a erosionarse de modo irreversible: se descomponen las aspiraciones nacionales, el sujeto pierde su núcleo sustancial y la cultura es un carrusel de esperanzas abortadas incapaces de responder a ninguna idea rectora. Y, sin embargo, en el paisaje de esta Europa tardomoderna en que se han agotado las pasadas ilusiones surge la idea de que el “hombre sin atributos” es también el “hombre de las posibilidades”.

    Robert Hooke (1635-1703) was a polymath who made important contributions to respiratory physiology and many other scientific areas. With Robert Boyle, he constructed the first air pump that allowed measurements on small animals at a reduced atmospheric pressure, and this started the discipline of high-altitude physiology. He also built the first human low-pressure chamber and described his experiences when the pressure was reduced to the equivalent of an altitude of ∼2,400 m. Using artificial ventilation in an animal preparation, he demonstrated that movement of the lung was not essential for life. His book Micrographia describing early studies with a microscope remains a classic. He produced an exquisite drawing of the head of a fly, showing the elaborate compound eye. There is also a detailed drawing of a flea, and Hooke noted how the long, many-jointed legs enable the insect to jump so high. For 40 years, he was the curator of experiments for the newly founded Royal Society in London and contributed greatly to its intellectual ferment. His mechanical inventions covered an enormous range, including the watch spring, the wheel barometer, and the universal joint. Following the Great Fire of London in 1666, he designed many of the new buildings in conjunction with Christopher Wren. Unfortunately, Hooke had an abrasive personality, which was partly responsible for a lack of recognition of his work for many years. However, during the last 25 years, there has been renewed interest, and he is now recognized as a brilliant scientist and innovator. ©2014 Int. Union Physiol. Sci./Am. Physiol. Soc.

    We investigate the generation and propagation of intense pulsed ion beams at the 6 MeV level and above using the Hermes III facility at Sandia National Laboratories. While high-power ion beams have previously been produced using Hermes III, we have conducted systematic studies of several ion diode geometries for the purpose of maximizing focused ion energy for a number of applications. A self-field axial-gap diode of the pinch reflex type and operated in positive polarity yielded beam power below predicted levels. This is ascribed both to power flow losses of unknown origin upstream of the diode load in Hermes positive polarity operation, and to anomalies in beam focusing in this configuration. A change to a radial self-field geometry and negative polarity operation resulted in greatly increased beam voltage (> 6 MeV) and estimated ion current. A comprehensive diagnostic set was developed to characterize beam performance, including both time-dependent and time-integrated measurements of local and total beam power. A substantial high-energy ion population was identified propagating in reverse direction, i.e. from the back side of the anode in the electron beam dump. While significant progress was made in increasing beam power, further improvements in assessing the beam focusing envelope will be required before ultimate ion generation efficiency with this geometry can be completely determined.

    In Tahiti he had ambitious writing plans but after four years of living in Tahiti, he left his plantation and sailed to the Cook Islands. He spent the rest of his life in the Cook Islands and married a local girl Ngatokorua. His new happiness gave him the inspiration to write. 29 sketches appeared in the United States in 1929, collected by The Century Company under the title of The Book of Puka-Puka. His second book My Tahiti, a book of memories, was published in 1937. After the death of Ropati 's beloved wife his goals were to bring up his children. But by this time Frisbie was seriously ill. The family left Puka-Puka and settled down on the uninhabited atoll of Suwarrow. Later on they lived on Rarotonga and Samoa where Frisbie was medically treated. Robert Dean Frisbie died of tetanus in Rarotonga on November 18, 1948. Frisbie wrote in a vivid, graceful style. His characters and particularly the atoll of Puka-Puka are memorably depicted. Gifted with a feeling for language and a sense of humor, he was able to capture on paper the charm, beauty, and serenity of life of the small islands in the South Pacific without exaggerating the stereotypical idyllic context and as such Frisbie's contribution to South Pacific literature went far deeper than that of many writers who have passed through the Pacific and wrote about their experiences. Frisbie's first book The Book of Puka-Puka was published in New York in 1929. It is the most endearing and the most original of his works. It was written during his lifetime on the atoll Puka-Puka in the Cook Islands. It is a collection of 29 short stories, episodic and expressively narrative in style. This is an account of life on Puka-Puka that criticizes European and American commercialism and aggressiveness, and presents the themes of the praise of isolation, the castigation of missionaries, and the commendation of Polynesian economic collectivism and sexual freedom. At the same time, the book presents a portrait of Frisbie himself

    Former CERN Director Robert Lévy-Mandel passed away on 3 July at the age of 87.   After obtaining a diploma from the Institut polytechnique in Grenoble, in 1948 he started work at the CEA, and was involved in the development and construction of the Saclay institute's first particle accelerator, a Van de Graaff machine. From 1954 to 1957 he was responsible for the coordination, development and construction of the CEA’s Saturne synchrotron, which entered service in 1958. In 1963 he was appointed head of the Saturne Synchrotron Department. The team led the construction of the Gargamelle bubble chamber, which was installed at CERN, and made contributions to other major facilities, including the Big European Bubble Chamber (BEBC). In 1971 he was invited to come to Geneva by John Adams, who was in charge of the SPS accelerator project.

    Tony came from Netherton, a small town near Birmingham in the English West Midlands, where he grew up with his parents, who ran the local grocery store, "T.W. Roberts & Son". This is where he regularly liked to return, firstly to help his parents and later simply to spend time with them. Here undoubtedly lie the roots of his organizational skills and his ability to get on so well with others. He soon became interested in the rapidly-developing field of computing and this was how he first came to CERN, during the summer of 1973, at the age of 25. He joined the DD Division as an operator responsible for the "calculators" of that time, where he stayed until 1979 when he joined the Fellows and Associates Section of Personnel Division. He participated in the general computerisation of the Administration and continued his career in the Records Office of HR Department, a post he held until the end. Though still very British – ob...

    Full Text Available In 2013 the Nobel Prize in Economic Sciences was awarded to the American economists, Eugene Fama, Lars Peter Hansen and Robert Shiller. The monetarists, Fama and Hansen, from the University of Chicago, and the Neo- Keynesian, Shiller, from the Yale University, according to the Swedish Royal Academy, won this prestigious prize for their research providing mathematical and economic models to determine (irregularities in the stock value trends at the stock exchanges. With his colleagues, in the 1960s Fama established that, in the short term, it is extremely difficult to forecast stock prices, given that new information gets embedded in the prices rather quickly. Shiller, however, determined that, although it is almost impossible to predict the stock prices for a period of few days, this is not true for a period of several years. He discovered that the stock prices fluctuate much more substantially than corporation dividents, and that the relationship between prices and dividends tends to decline when high, and to grow when low. This pattern does not apply only to stocks, but also to bonds and other forms of capital.

  16. Robert Wood Johnson Foundation Nurse Faculty Scholars program leadership training.

    Campbell, Jacquelyn C; McBride, Angela Barron; Etcher, LuAnn; Deming, Katie

    The Robert Wood Johnson Foundation Nurse Faculty Scholars program was created to address the nursing shortage via development of the next generation of national leaders in academic nursing. The leadership training combined development at the scholar's home institution with in-person didactic and interactive sessions with notable leaders in nursing and other disciplines. A curriculum matrix, organized by six domains, was evaluated quantitatively and qualitatively. What set this program apart is that it immersed junior faculty in concerted leadership development with regard to all aspects of the faculty role so that teaching interactively, making use of the latest in information technology, giving testimony before a policy-making group, participating in strategic planning, and figuring out how to reduce the budget without jeopardizing quality were all envisioned as part of the faculty role. The domains covered by this program could easily be used as the framework to plan other leadership-development programs for the next generation of academic leaders. Copyright © 2017 Elsevier Inc.

  18. Statistical ultrasonics: the influence of Robert F. Wagner

    Insana, Michael F.

    2009-02-01

    An important ongoing question for higher education is how to successfully mentor the next generation of scientists and engineers. It has been my privilege to have been mentored by one of the best, Dr Robert F. Wagner and his colleagues at the CDRH/FDA during the mid 1980s. Bob introduced many of us in medical ultrasonics to statistical imaging techniques. These ideas continue to broadly influence studies on adaptive aperture management (beamforming, speckle suppression, compounding), tissue characterization (texture features, Rayleigh/Rician statistics, scatterer size and number density estimators), and fundamental questions about how limitations of the human eye-brain system for extracting information from textured images can motivate image processing. He adapted the classical techniques of signal detection theory to coherent imaging systems that, for the first time in ultrasonics, related common engineering metrics for image quality to task-based clinical performance. This talk summarizes my wonderfully-exciting three years with Bob as I watched him explore topics in statistical image analysis that formed a rational basis for many of the signal processing techniques used in commercial systems today. It is a story of an exciting time in medical ultrasonics, and of how a sparkling personality guided and motivated the development of junior scientists who flocked around him in admiration and amazement.

    Full Text Available This paper analyzes Robert Lucas's contribution to economic theory between 1967 (year of his first solo publication and 1981 (the year before the emergence of Real Business Cycle approach, and it has two parts. The first one, using citation data from three different sources, we try to answer two questions: (i What are Lucas's most influential papers currently? (ii How has this influence changed through time? We show, for instance, that according to two of those three sources, Lucas's most influential paper today is not from his business cycle research agenda, which gave him his Nobel Prize in 1995. Moreover, it is clear the loss of influence of Lucas's macroeconomic theory since the early 1980s. In the second part, by cataloging all the works that Lucas had used as bibliographical references in his papers and separating them in two categories (positive and negative, we try to understand who exerted influence on him. We show that the author that Lucas most cited in a positive context were John Muth, Milton Friedman and Edmund Phelps. The authors more often cited in a negative context were John M. Keynes and A. W. Phillips. We discuss the reasons behind this data.

  20. Robert Boyle and the representation of imperceptible entities.

    Science.gov (United States)

    Wragge-Morley, Alexander

    2018-03-01

    In this essay, I examine Robert Boyle's strategies for making imperceptible entities accessible to the senses. It is well known that, in his natural philosophy, Boyle confronted the challenge of making imperceptible particles of matter into objects of sensory experience. It has never been noted, however, that Boyle confronted a strikingly similar challenge in his natural theology - he needed to make an equally imperceptible God accessible to the senses. Taking this symmetrical difficulty as my starting point, I propose a new approach to thinking about the interconnections between Boyle's natural philosophy and natural theology. For the most part, studies of science and religion in the early modern period work by seeking out the influence of explicitly stated religious beliefs on scientific ideas. I argue, by contrast, that we need to focus on Boyle's representational practices, using his attempts to represent imperceptible entities as a means of uncovering metaphysical and theological presuppositions that he did not always articulate when stating his religious beliefs. With new interpretations of both A Discourse of Things Above Reason (1681) and Some Physico-Theological Considerations about the Possibility of the Resurrection (1675), I show that there were crucial similarities between Boyle's practices for representing both God and atoms. I go on to show, moreover, that Boyle used these practices to enact an ontological stance at odds with one of his most important professed beliefs.

    The optical properties of silica aerogel tiles with a refractive index of 1.03 and dimensions 11x11x1 cm sup 3 , produced by the Matsushita Electric Works (Japan), have been measured in the wavelength range from 200 to 900 nm. The tiles are used as one of the two radiators of the ring imaging Cherenkov counter of the HERMES experiment at DESY-HERA. The transmittance of light has been measured on 200 tiles by means of a double beam spectrophotometer. The light transflectance and reflectance have been measured on one tile by means of a single-beam spectrophotometer and an integrating reflecting sphere. Typical values of the measured transmittances at a wavelength lambda=400 nm are around 0.67. The measured transflectance increases almost linearly from 0.4 to 0.96 in the interval 200-300 nm, and remains nearly constant at the value 0.95 in the complementary lambda-range. The measured reflectance, mostly confined below 400 nm, is completely interpretable as backscattering from inside the aerogel, revealing an abs...

    The reliability of infrared (IR) and ultraviolet (UV) emissions to measure star formation rates (SFRs) in galaxies is investigated for a large sample of galaxies observed with the Spectral and Photometric Imaging Receiver (SPIRE) and the Photodetector Array Camera and Spectrometer (PACS) instruments on Herschel as part of the Herschel Multi-Tiered Extragalactic Survey (HerMES) project. We build flux-limited 250-μm samples of sources at redshift z 500 μm. Dust attenuation is discussed on the basis of commonly used diagnostics: the LIR/LUV ratio and the slope, β, of the UV continuum. A mean dust attenuation AUV of mag is measured in the samples. LIR/LUV is found to correlate with LIR. Galaxies with and 0.5 recipe commonly applied to local starbursts is found to overestimate the dust attenuation correction in our galaxy sample by a factor of ~2-3. The SFRs deduced from LIR are found to account for about 90 per cent of the total SFR; this percentage drops to 71 per cent for galaxies with (or ). For these faint objects, one needs to combine UV and IR emissions to obtain an accurate measure of the SFR.

    To evaluate the effectiveness of the Robert view in assessing trapeziometacarpal arthrosis and to compare the accuracy of the Robert and lateral views in staging trapeziometacarpal (TM) joint arthrosis. Patient demographics were obtained. Four participating raters reviewed 62 randomly selected thumb x-rays of patients presenting with thumb TM joint pain. Lateral and Robert-hyperpronation views were assessed using an analysis of 13 criteria. X-rays of 62 thumbs for 58 patients were evaluated. The average patients' age was 64 (47-87) and 51 (80%) were females. The majority of X-rays evaluated fell into stage 3. Stage 2 was the second most common level of arthritis encountered and the least was stage 1. More osteophytes were encountered in the trapezium than metacarpal on both the Robert and lateral views. The Robert view was superior in detecting osteophytes on the trapezium than the lateral view. Osteophyte size varied from 1.7 to 2 mm. The lateral view displayed 61 cases with dorsal metacarpal subluxation (98%). The Robert view displayed 48 cases (77%) with radial metacarpal subluxation and 9 cases (15%) with ulnar metacarpal subluxation. Thumb metacarpal adduction deformity was encountered on the lateral view in 20 cases (32%) whereas on the Robert view it was encountered in 14 cases (23%). Subchondral sclerosis was encountered on the Robert view in 56 thumbs (90%) while it was seen on the lateral view in 52 thumbs (84%). Pantrapezial arthritis involving the STT joint was encountered equally in 16 cases (26%) on the Robert view and the lateral views. The study found a moderate level of interrater reliability on both the lateral and Robert views. With the exception of osteophytes encountered on the trapezium versus the metacarpal, there were no other statistically significant findings. This study confirms that each of the Robert and lateral views offer unique information and combining both views enhances the ability to assess radiographic disease severity, and

    The paper summarises the accessible literature on the life and work of well-known American lung surgeon, Professor Dr. Med. Robert Klopstock, who was in the years 1920-1924 a friend Franz Kafka. Professor Klopstock was of Hungarian origin and he got acquainted with Franz Kafka at the end of the year 1920 in Tatranské Matliare (The High Tatras). They were both patients treated for lung tuberculosis. They became close friends and their mutual correspondence shows their real friendship. Robert Klopstock was present at Franz Kafka's death-bed on June 3, 1924 in Kierling, near Klosterneuburg, not far from Vienna. Robert Klopstock studied at Medical Faculties of the Universities in Budapest, Prague, Kiel and Berlin. After his graduation in 1933 in Berlin, he worked as a lung surgeon at various surgical clinics and departments in Budapest and Berlin. In 1936 Robert Klopstock together with his wife visited the High Tatras and Tatranské Matliare. In 1937 Robert Klopstock with his wife Gizela, a writer and a translator, who translated the first chapters of Franz Kafka's novel "Trial" into Hungarian language, went to United States of America. During his stay in U.S.A. Dr. Med. Robert Klopstock was very active as a lung surgeon and a scientist. He published 64 specialized scientific papers, mostly in American medical journals. He became Professor of Lung Surgery at Downstate Medical Centre in New York-Brooklyn. He died on June 15, 1972 in New York.

    Ralph Robert Robbins, Jr., died on 2 December 2005, in Kyle, Texas. His wife, Maria Elena Robbins, his daughters Julia Robbins Kelso and Stephanie Juarez Balles, his son Matthew Juarez, and five grandchildren survive him. Bob was on the faculty at the University of Texas from 1968 until his retirement in 2003. Bob was born in Wichita, Kansas, on 2 September 1938, the only son of Mildred and Ralph Robert Robbins, Sr. Guided by his high school's policy to provide a practical education to children of working-class parents, Bob began high school with a heavy dose of vocational courses until the results of a test indicated his special talent in mathematics. He was awarded a full scholarship to Yale University, graduating magna cum laude in mathematics in 1960. He won the Warner Prize in Mathematics at Yale that year. He received his Ph.D. in 1966 with a dissertation entitled "The Triplet Spectrum of Neutral Helium in Expanding Nebulae" from the University of California at Berkeley. His interest in college teaching was ignited at this time through summer teaching positions at San Mateo California Junior College and the Ohio State University. Following a year at Texas as a McDonald Observatory Post-doctoral Fellow, Bob taught for a year in the physics department of the University of Houston before returning to the University of Texas at Austin as an Assistant Professor of Astronomy in 1968. He was promoted to Associate Professor in 1972. Bob's research in the early 1970s on theoretical studies of helium was of vital importance to astronomers for over three decades. These pioneering calculations became vital to observational astronomers in the mid-1990s as interest grew in the primordial helium produced by the Big Bang. Bob's interest and influence in education was international in scope. In the summers 1968-1970, he was a government consultant in Mathematics in East Pakistan (now Bangladesh). He consulted with the government that was preparing a master plan for technical

    The publishers of Physics in Medicine and Biology (PMB), IOP Publishing, in association with the journal owners, the Institute of Physics and Engineering in Medicine (IPEM), jointly award the Roberts prize for the best paper published in PMB during the previous year. The procedure for deciding the winner is a two-stage process. First, a shortlist of contenders is drawn up based on those papers that had the best referees' quality assessments, with a further quality check and endorsement by the Editorial Board. The papers on the shortlist are then reviewed by a specially convened IPEM committee consisting of members with fellow status. This committee reads the shortlisted papers and selects the winner. We have much pleasure in advising readers that the Roberts Prize for the best paper published in 2012 is awarded to Michel Defrise, Ahmadreza Rezaei and Johan Nuyts from the Vrije Universiteit Brussels and the Katholieke Universiteit Leuven, Belgium for their breakthrough paper that describes how the information needed for attenuation correction in PET imaging can be extracted, to within a constant, from time-of-flight emission data: Time-of-flight PET data determine the attenuation sinogram up to a constant 2012 Phys.

    In this thesis, the measurement of an azimuthal amplitude of the asymmetry in the lepto-production of {pi}{sup +}{pi}{sup -} pairs at the HERMES experiment is reported. The experiment was carried out at DESY in Germany, utilizing the longitudinally polarized 27.6 GeV electron/positron beam of the HERA storage ring in combination with a longitudinally or transversely polarized gaseous target internal to the beam pipe. For the present measurement, the transversely polarized proton target was used and the beam polarization was averaged out in order to measure the asymmetry A{sub UT}. A Ring Imaging Cerenkov (RICH) detector allows the precise identification of pions, kaons and protons over essentially the entire momentum range of the experiment. The asymmetry A{sub UT} for {pi}{sup +}{pi}{sup -} pair production was measured for the first time in the world by HERMES. The amplitudes are extracted as functions of different kinematic variables, which can facilitate the comparison with the theoretical models and the extraction of transversity with combination of the measurement of the dihadron fragmentation function.

Identifications of such specific cytogenetic findings can be the key factor that leads towards the diagnosis of syndromes like Roberts SC phocomelia. The case presented here as Roberts SC phocomelia syndrome was identified as a child with multiple congenital anomalies and dysmorphic features. Conventional cytogenetic analysis of the case revealed premature sister chromatid separation. The premature centromeric separation was also confirmed by C banding analysis of the child. It is the first and the only case of Roberts SC phocomelia diagnosed from this part of the world. The present case report emphasizes the importance of conventional cytogenetics in the diagnosis of such syndromes.

  8. Numerical Methods in Atmospheric and Oceanic Modelling: The Andre J. Robert Memorial Volume

    Science.gov (United States)

    Rosmond, Tom

    Most people, even including some in the scientific community, do not realize how much the weather forecasts they use to guide the activities of their daily lives depend on very complex mathematics and numerical methods that are the basis of modern numerical weather prediction (NWP). André Robert (1929-1993), to whom Numerical Methods in Atmospheric and Oceanic Modelling is dedicated, had a career that contributed greatly to the growth of NWP and the role that the atmospheric computer models of NWP play in our society. There are probably no NWP models running anywhere in the world today that do not use numerical methods introduced by Robert, and those of us who work with and use these models everyday are indebted to him.The first two chapters of the volume are chronicles of Robert's life and career. The first is a 1987 interview by Harold Ritchie, one of Robert's many proteges and colleagues at the Canadian Atmospheric Environment Service. The interview traces Robert's life from his birth in New York to French Canadian parents, to his emigration to Quebec at an early age, his education and early employment, and his rise in stature as one of the preeminent research meteorologists of our time. An amusing anecdote he relates is his impression of weather forecasts while he was considering his first job as a meteorologist in the early 1950s. A newspaper of the time placed the weather forecast and daily horoscope side by side, and Robert regarded each to have a similar scientific basis. Thankfully he soon realized there was a difference between the two, and his subsequent career certainly confirmed the distinction.

The Supreme Court has tried to find a balance between the Establishment Clause of the U.S. Constitution and the inclusion of religious expressions in government activities. In Town of Greece v.

The essay critically examines the various opinions in the case, and looks at where this decision suggests the Establishment Clause doctrine is moving award.

    Hristova, I.

    2007-12-15

    We present the analysis of data taken in the years 2002-2004 with the 27.56 GeV positron beam of the HERA storage ring at DESY and the internal transversely polarised hydrogen fixed target of the HERMES experiment. Events with a scattered positron and a produced pion are selected. Exclusive production of single pions, e{sup +}p{yields}e{sup +'}n{pi}{sup +}, is ensured by requiring the missing mass in the event to be equal to the mass of the neutron, which is not detected. The cross section for this process depends on the Bjorken scaling variable, the four-momentum transfer, and the transverse four-momentum transfer, whose average values for our sample are left angle x right angle =0.12, left angle Q{sup 2} right angle =2.3 GeV{sup 2}, left angle t' right angle =-0.18 GeV{sup 2}, respectively, and two azimuthal angles: the angle {phi} between the scattering and production planes (their common line contains the virtual photon), and the angle {phi}{sub S} between the scattering plane and the target polarisation vector. The hard scattering is selected by requiring Q{sup 2}>1 GeV{sup 2}. The asymmetry, also called transverse-target single-spin azimuthal asymmetry, is defined as the ratio of the difference to the sum of the cross sections for positive and negative target polarisation. It is characterised by six azimuthal sine modulations, whose amplitudes can vary from -1 to 1. We measure the asymmetry from a sample of 2093 events with a signal-to-background ratio of 1: 1. At average kinematics, the values of the amplitudes are found to be small or consistent with zero, except for the amplitude A{sup sin{phi}{sub SUT,meas}}=0.38{+-}0.06(stat){sup +0.12}{sub -0.06}(syst). The amplitude of main interest for comparison with theory, A{sup sin({phi}-{phi}{sub S})}{sub UT,meas}=0.09{+-}0.05(stat){sup +0.10}{sub -0.03}(syst), after correction for the background contribution becomes A{sup sin({phi}-{phi}{sub S})}{sub UT,bg.cor}=0.22 {+-}0.13(stat){sup +0.10}{sub -0

    Gerkes, Erica H; van der Kevie-Kersemaekers, Anne-Marie F; Yakin, Mariam; Smeets, Dominique F C M; van Ravenswaaij-Arts, Conny M A

    Roberts syndrome/SC phocomelia is a rare, autosomal recessive syndrome characterised by pre- and postnatal growth retardation, microcephaly, craniofacial anomalies, mental retardation, and tetraphocomelia in varying degrees of severity. The clinical diagnosis can be challenging in phenotypically mild cases. In the extremely mild case presented here, specific mitotic abnormalities were detected and proved to be very helpful, since Roberts syndrome/SC phocomelia could be diagnosed after finding premature centromere separation and somatic aneuploidy at routine karyotyping. We discuss these and other mitotic cytogenetic abnormalities that can be of significant diagnostic importance, but which will be missed if only array studies are performed. We also discuss the difference between premature centromere separation and premature (sister) chromatid separation. Copyright (c) 2009 Elsevier Masson SAS. All rights reserved.

    2006-08-01

    Robert Hooke (1635-1703), an assistant researcher to Robert Boyle (1627-1691), invented the first functional British air pump. Applying it to scientific research, Hooke operated the world's first hypobaric chamber in 1671, using it for self-experimentation. He recorded the first physiological observations in an artificial altitude-equivalent environment up to 2400 m. Though Hooke's experiment showed some methodological insufficiencies, his imaginative experimental techniques were remarkable for their time and were indicative of the lively intellectual atmosphere of the Royal Society and the significant contributions of Hooke, who was a member. Two centuries passed before the French physiologist Paul Bert (1830-1886) conducted his famous laboratory-supported investigations of high altitude physiology. Bert played a decisive role in the discovery of the causes of decompression sickness; a contribution Hooke could not make due to the technical deficiencies of the 17th century.

  11. [Robert Koch was right. Towards a new interpretation of tuberculin therapy].

    Science.gov (United States)

    Cardona, Pere J

    2006-01-01

    At the centenary of Robert Koch's Nobel Prize award, tuberculosis treatment with tuberculin, which was announced in Berlin in 1890, is still considered a failure. Nevertheless, there is now sufficient information supporting the idea that tuberculin therapy was widely used until the second half of the twentieth century; thus, the impact of this treatment should be studied and related to the decrease in tuberculosis-related mortality recorded in that period. Moreover, tuberculin therapy has inspired at least two new immunotherapies; these, however, were directed toward precisely the opposite effect: suppression of the Koch phenomenon. Thus, inoculation of Mycobacterium vaccae polarizes the immune response towards the Th1 type; and inoculation of RUTI avoids local immunodepression after short-term chemotherapy without inducing toxicity. For this reason, Robert Koch's work on antituberculosis therapy should be reread and proper recognition given to his contribution in this field.

    In this issue of Reproductive BioMedicine Online, Benagiano, Carrara and Filippi have produced a clearly written and comprehensive account of why the Roman Catholic Church has not welcomed the award of the 2010 Nobel Prize in Physiology and Medicine to Dr Robert G Edwards for the development of human IVF. I commend the article for its clarity and lucidity but attempt to point out some areas where disagreement even with its nuanced opposition to IVF may be legitimate. I try to make some simple comments that explain why this is so and I suggest some areas to which contemporary theology and philosophy can commit itself. But it is good to see even a nuanced response to the work of Robert G Edwards rather than a blanket condemnation. Copyright © 2011 Reproductive Healthcare Ltd. Published by Elsevier Ltd.

  14. Charles Robert Darwin and Alfred Russel Wallace: their dispute over the units of selection.

    2013-12-01

    Charles Darwin and Alfred Russel Wallace independently discovered the mechanism of natural selection for evolutionary change. However, they viewed the working of selection differently. For Darwin, selection was always focused on the benefit for the individual. For Wallace, selection was as much something of benefit for the group as for the individual. This difference is traced to their different background political-economic views, with Darwin in favor of Adam Smith's view of society and Wallace following Robert Owen in being a socialist.

  1. Homosexual orientation-from nature, not abuse: A critique of Roberts, Glymour, and Koenen (2013).

    Science.gov (United States)

    Rind, Bruce

    2013-11-01

    Roberts, Glymour, and Koenen (2013), using instrumental variable models, argued that child abuse causes homosexual orientation, defined in part as any same-sex attractions. Their instruments were various negative family environment factors. In their analyses, they found that child sexual abuse (CSA) was more strongly related to homosexual orientation than non-sexual maltreatment was, especially among males. The present commentary therefore focused on male CSA. It is argued that Roberts et al.'s "abuse model" is incorrect and an alternative is presented. Male homosexual behavior is common in primates and has been common in many human societies, such that an evolved human male homosexual potential, with individual variation, can be assumed. Cultural variation has been strongly influenced by cultural norms. In our society, homosexual expression is rare because it is counternormative. The "counternormativity model" offered here holds that negative family environment weakens normative controls and increases counternormative thinking and behavior, which, in combination with sufficient homosexual potential and relevant, reinforcing experiences, can produce a homosexual orientation. This is a benign or positive model (innate potential plus release and reinforcement), in contrast to Roberts et al.'s negative model (abuse plus emotional compensation or cognitive distortion). The abuse model is criticized for being based on the sexual victimological paradigm, which developed to describe the female experience in rape and incest. This poorly fits the gay male experience, as demonstrated in a brief non-clinical literature review. Validly understanding male homosexuality, it is argued, requires the broad perspective, as employed here.

  2. John Bingham Roberts and the first American monograph on human brain surgery.

    Science.gov (United States)

    Stone, J L

    2001-10-01

    JOHN BINGHAM ROBERTS (1852-1924) of Philadelphia was an active general surgeon in the latter 19th and early 20th centuries. He made pioneering contributions to a number of areas of surgery. From 1880 until the end of his career, he was one of the few American surgeons to advocate an aggressive exploratory approach to cranial fractures in an effort to avoid consequences such as infection, delayed seizures, and insanity. In his 1885 article in the Transactions of the American Surgical Association titled "The Field and Limitation of the Operative Surgery of the Human Brain," he predicted that with antiseptic precautions and the growing knowledge of cerebral localization, operations on the brain would become commonplace. This work predated that of Horsley, Keen, and many others. Roberts had a continuing interest in head injuries, cranial fractures, and the development of trephines and burrs for reconstructive cranial work, but his active enthusiasm for brain surgery diminished in the 1890s. Nevertheless, Roberts was a very prolific teacher and leader in American surgery who is perhaps best remembered for his monographs and textbooks on general, orthopedic, plastic, and reconstructive surgery.

O objetivo deste estudo foi avaliar as causas e consequências das mudanças do uso e cobertura da terra na microbacia hidrográfica do córrego Hermes, através da aplicação de método espacial e não espacial de geoprocessamento. Os resultados analíticos de métricas de paisagem indicam que 82,76% da área correspondem a uma matriz de pastagem de gramíneas, e que 14,64% reportam-se a cobertura vegetal nativa seccionada em 18 fragmentos pouco inter-relacionados, havendo ainda 1,94% e 0,66% relativos à agricultura (lavoura perene e anual e áreas edificadas, respectivamente. Depreende-se, por fim, que o intenso desflorestamento, com fins de aumento de áreas destinadas às atividades de agropecuária, é a principal causa da devastação da floresta de transição na MBCH-RO, emanando desta outras formas de degradação ambiental, como erosão, assoreamento dos cursos de água perenes, aumento da carga de partículas em suspensão e dissolvidas, e, por fim, modificação dos ciclos hidrológicos e de carbono em escalas local, regional e global.

  4. Io, Argus, Hermes, Syrinx: An Example of the In_uence Excersiced by Ovid’s Metamorphoses on Ancient Roman Painting

    Full Text Available Although a main source of iconography ever since the Middle Ages, the influence of Ovid’s Metamorphoses on Ancient Roman visual arts has been presupposed rather than researched in detail. This lacuna in ancient iconography has been filled by the research project MetaMArS, Le Metamorfosi di Ovidio: Mito, Arte, Società, headed by Professor Francesca Ghedini of Padua University. The aim of the project is the systematic study of mutual influences between Ovid and the art of the Roman period. The research is based on a four-step methodology: (1 selecting the subject-matter and compiling an inventory of all literary and iconographic testimonies relating to it; (2 dividing Ovid’s narrative into episodes, i.e. acts and scenes; (3 classifying the iconographic repertoire by themes and schemes; (4 identifying the convergences/ divergences between the two parallel series. Following the above methodology, the paper focuses on the myth of Io woven by Ovid into Book 1 of the Metamorphoses (ll. 568–750. The lines have been divided into a prologue and five acts, with each of the latter subdivided into two scenes, while Act 4 subsumes the passage on Pan and Syrinx as well. In the opinion of Franz Bömer, it is the Syrinx element that is Ovid’s original contribution: thus both the Syrinx figure and the entire first scene of Act 4, which has Hermes in a shepherd’s attire beguile Argus by playing a new instrument, are crucial to establishing a potential in_uence of the Metamorphoses on select Roman iconography. The iconographic theme of Io, Argus, and Hermes is represented in Roman wall painting by eleven pictures, which may be divided into bi-figural and three-figural depictions, with the former corresponding to Act 3, Scene 1, and the latter to Act 4, Scene 1. In terms of composition, the images follow four schemes, the second of which includes two variants. Schemes 3 (in the House of the Citharist at Pompeii and 4 (in the temple of Isis at Pompeii

    Full Text Available The Robert/SC (pseudothalidomide syndrome is a rare autosomal recessive disorder, associated with phocomelia and craniofacial abnormalities. An anomalous fetus with lower limb phocomelia and micromelia, lumbar myeloschisis, upper limb and ribs defects and craniofacial abnormalities is reported whose diabetic mother took mebendazole and glibenclamide in early pregnancy. Ultrasonographic findings of syndromes with phocomelia are discussed as well as Robert/SC syndrome which is the most probable diagnosis. Robert/SC phocomelia syndrome is a rare autosomal recessive condition characterized by severe pre and postnatal growth deficiency, symmetric limb reductions of variable severity and craniofacial anomalies including hypertelorism, hypoplastic nasal alae, cleft lip and palate. About half of the reported cases presented chromosomal abnormalities. We think that findings in our case are consistent with Robert/SC syndrome with additional abnormalities.

    Full Text Available Despite the fact that Robert Harley is known as Tory politician, he began his career as a Whig politician. His grandfather and father were Presbyterians, and Robert Harley himself was a Presbyterian during his entire life. Harley’s family supported the Glorious Revolution of 1688. In 1689 Robert Harley was first elected to the House of Commons as a representative of the Whig party. Thanks to his wife’s Foley family, Robert Harley was elected as a commissioner of public accounts in the House of Commons. In 1689 Britain entered the “war of King William” which was a burden for many gentry (Whigs or Tories. Robert Harley became famous in the parliament as a critic of the war and corruption in the army. In 1693 the Whig leaders headed the ministry and continued the war. Their policy divided the Whigs party in two factions: “Court Whigs” and “Country Whigs”. Robert Harley and his supporters became “Country Whigs”, and they criticized the “Court Whigs”. By 1700 Robert Harley joined the Tory party. The article also describes the evolution of historiography of Harley‘s policy. Victorian historians have called the Prime Minister a “stupid person”. The same opinion was repeated by Russian historians of the 19th century. But in the 20th century the assessment of Robert Harley’s activity was changed by the works of K. Feiling, G. Holmes, B.W. Hill and other historians. Soviet historians (for example M.A. Barg also called R.Harley a “mediocre politician”, but modern Russian historians (L.I. Ivonina, T.L. Labutina and others consider him a “clever statesman” and a “master of political intrigues and parliamentary diplomacy”.

    2018-05-01

    We investigated almost 500 stars distributed among 193 binary or multiple systems made of late-F, G-, or early-K primaries and late-K or M dwarf companion candidates. For all of them, we compiled or measured coordinates, J-band magnitudes, spectral types, distances, and proper motions. With these data, we established a sample of 192 physically bound systems. In parallel, we carried out observations with HERMES/Mercator and obtained high-resolution spectra for the 192 primaries and five secondaries. We used these spectra and the automatic STEPAR code for deriving precise stellar atmospheric parameters: Teff, log g, ξ, and chemical abundances for 13 atomic species, including [Fe/H]. After computing Galactocentric space velocities for all the primary stars, we performed a kinematic analysis and classified them in different Galactic populations and stellar kinematic groups of very different ages, which match our own metallicity determinations and isochronal age estimations. In particular, we identified three systems in the halo and 33 systems in the young Local Association, Ursa Major and Castor moving groups, and IC 2391 and Hyades Superclusters. We finally studied the exoplanet-metallicity relation in our 193 primaries and made a list 13 M-dwarf companions with very high metallicity that can be the targets of new dedicated exoplanet surveys. All in all, our dataset will be of great help for future works on the accurate determination of metallicity of M dwarfs.

    2008-01-01

    Roberts' model of lunar soil erosion beneath a landing rocket has been updated in several ways to predict the effects of future lunar landings. The model predicts, among other things, the number of divots that would result on surrounding hardware due to the impact of high velocity particulates, the amount and depth of surface material removed, the volume of ejected soil, its velocity, and the distance the particles travel on the Moon. The results are compared against measured results from the Apollo program and predictions are made for mitigating the spray around a future lunar outpost.

    Roberts/SC phocomelia syndrome (RBS) is a rare but distinct genetic disorder with an autosomal recessive inheritance pattern. It has been associated with microcephaly, craniofacial malformation, cavernous hemangioma, encephalocele, and hydrocephalus. There are no previously reported cases of RBS with intracranial aneurysms. The authors report on a patient with a history of RBS who presented with a spontaneous posterior fossa hemorrhage. Multiple small intracranial aneurysms were noted on a preoperative CT angiogram. The patient underwent emergency craniotomy for evacuation of the hemorrhage. A postoperative angiogram confirmed the presence of multiple, distal small intracranial aneurysms.

    Attempting to play the role of King Solomon in his PPACA decision, Chief Justice John Roberts split the baby perversely by ruling it was not a tax under the Anti-Injunction Act, which would have likely deprived the Court of jurisdiction to hear this pre-enforcement challenge to the individual mandate, but it was a tax for taxing and spending purposes even though Congress said it was a "penalty" and not a tax. And the Chief Justice had to twist further his "wisdom" to hold that it was not an unconstitutional direct tax, even though that is exactly what it is, if it is a tax in the first instance.

    Robert Hooke played important roles in the early development of the Royal Society of London. As Curator of Experiments of the Society, he became a pioneering microscopist, prolific inventor, astronomer, geologist, architect, and an effective surveyor of the City of London following the Great Fire of 1666. Hooke's Micrographia (1665) revealed the microscopic structures of numerous biological and inorganic objects and became an important source of information for later studies. Aside from the body of detailed observations reported and depicted in Micrographia, the Preface is in itself an extraordinary document that exhibits Hooke's fertile mind, philosophical insights, and rare ability to look into the future.

    2014-01-01

    In an influential article of 1952, Thomas Kuhn argued that Robert Boyle had little or no influence on the subsequent development of chemistry. This essay challenges Kuhn's view on two fronts. First, it shows that Johann Joachim Becher developed his hierarchical matter theory under the influence of Boyle and then transmitted it to the founder of the phlogiston theory, G. E. Stahl. Second, this essay argues that transmutational matter theories were not necessarily opposed to the existence of stable chemical species, pace Kuhn. Boyle's corpuscular theory descended largely from the tradition of "chymical atomism," which often advocated both chrysopoeia and the reality of robust chemical substances.

    As editors of the Robert Wood Johnson Foundation's (RWJF's) anthology series, we have examined the entire range of the foundation's grant making since 1972. We found that the RWJF has enjoyed considerable success in building fields--from nurse practitioners to tobacco control to end-of-life care. The RWJF has done this by shaping fields as they were emerging, by adopting a wide-ranging "bear hug" approach, and by staying the course. The lessons from the RWJF's field-building efforts are relevant for both large and small foundations: Small funders can develop strategic plans aimed at building fields in their home state or locality.

    Full Text Available To a considerable extent, Romantic Orientalist literature is founded on scholasticism, authentication, quotation of antiquarian sources, in other words, on paratext. It constitutes in many respects an oxymoronic, though fascinating and dynamic, symbiosis of repetition / replication and creative imagination / invention. By focusing on Robert Southey’s art of quotation in his extraordinarily abundant notes to his orientalist narrative verse this essay seeks to establish paratext as an integral, formative aspect of Romantic Orientalism and Romantic-period poetics, illustrating the hybridity of the Romantic genius and Romantic poetic creation, and challenging common assumptions about a sublime, universal Romantic-period poetry.

    2017-10-01

    After the First World War, the young Soviet Union (USSR) desperately needed new engineers and scientists who would provide the new country with development of modern industry and transportation. At that time, Western European countries had knowledge and experience, especially in the field of aviation. One of the young engineers was Robert Bartini, who was educated in Austria-Hungary and Italy, and graduated from Milan Polytechnic Institute. In 1923, he fled Italy to escape Fascists and emigrated in Soviet Union. This article is a brief description of aircraft designer Robert Bartini and his role in the development of the military, passenger and transport aviation. In addition, it presents his vision of the intercontinental and continental high-speed transport, which was his focus in the last years of his work and creation. He worked as a researcher and expert in the former Soviet Union, therefore, more detailed and relevant information on his work has been revealed to the public in recent years. In Russia, he is very popular as a researcher and developer. There are many books about him in Russian and Italian language, but not in English. Thus, his work is still quite unknown in the West. He was born in Kanjiza (today Serbia) in 1897, and spent his youth in Fiume (Rijeka, today Croatia).

    2016-02-01

    Full Text Available The works of Sir James George Frazer had an outstanding influence on the literature of modernism. Among those who benefited from Frazer’s ritualism were W. B. Yeats, T. S. Eliot. James Joyce, Ernest Hemingway, D. H. Lawrence, Ezra Pound, Mary Renault, Joseph Campbell, Robert Graves and many others. Robert Graves was known for his famous adaptation of Frazer’s concept of the sacred king who is sacrificed for the benefit of his subjects thus forming the narrative frame for the one of his most controversial novels. The dying king is also identified with the poet striving to attain the favour of the Triple Muse Goddess - who represents the embodiment of true poetic inspiration. The aforementioned concept is not the only thing that Graves inherited from his famous ancestor. In our analysis we laid stress on the customs, rituals, magic symbols and deities both authors dealt with. We also observed a striking resemblance of the style Greves and Frazer developed and their euchemeristic approach to myths as well.

  17. Polarization, motion, and fragmentation. Exploring the role of quarks in the nucleon through semi-inclusive longitudinal spin asymmetries at HERMES

    International Nuclear Information System (INIS)

    Rubin, Joshua George

    2009-11-01

    The motivation for this work was to improve upon prior analyses that extracted the quark helicity distributions, Δ(x), of the proton. Chapter 4 contains several new double-spin asymmetries which are results in their own right. The ph? dependence is plotted for the first time with HERMES data which is uniquely hadron separated. The hadron charge difference asymmetry is presented which, in combination with the quark helicity densities can put limits on fragmentation symmetry breaking in semi-inclusive DIS. Additionally, a novel method of unfolding yields (reducing smearing effects from detector resolution limitations and QED radiation) was developed and presented here for the first time which potentially allows new kinds of asymmetries to be constructed which were unavailable before. Also, this chapter describes the method by which the first ever three dimensionally binned SIDIS double-spin asymmetries were produced. These asymmetries, which will be used as the data inputs for the Δ(x) extraction, are valuable inputs to world fits being performed by theorists. Chapter 5 further explores this idea of fragmentation symmetry breaking with Monte Carlo studies of fragmentation functions. These studies test assumptions which are frequently made in the interpretation of asymmetries like the hadron charge difference of the prior chapter and suggest that these assumptions should be approached with some caution. Also, a technique for tuning and more importantly propagating systematic uncertainty through non-analytic Monte Carlo models, like the Lund-String model which provides an essential input to the Δ(x) extraction, is developed (orig.)

    Full Text Available Já virou lugar comum dizer que se é pós-positivista. Entretanto, pouco se sabe o que realmente seja o positivismo jurídico ( em suas várias facetas, confundindo esse movimento com a mera aplicação da litaralidade da lei. Nesse sentido, não se pode admitir argumentos que afastam o conteúdo de uma lei, democraticamente legitimada, com base numa suposta "superação" da literalidade do texto legal. Desse modo, para veificar o papel do intérprete do direito, faz-se necessária a desconstrução de uma tese que vem servindo de base para a caracterização dos modelos de direito e de juiz nos diversos sistemas jurídicos contemporâneos, os conhecidos juízes Hércules, Júpiter e Hermes (Ost, que tem levado a diversos e diferentes equívocos na teoria do direito.

    2007-09-01

    This article investigates the influence of perception that is altered by psychedelic drugs on processes of creativity through a case study of the work of well-known comic artist Robert Crumb. Samples of Crumb's work before, during, and after the period of his use of psychedelic drugs are content analyzed and compared according to the categorization offered by Janiger and Dobkin de Rios (1989). The results of the comparison indicate that Robert Crumb's drug use significantly altered the stylistic approach of his artwork not only during the period of his drug use, but long after he had stopped using drugs.

    Full Text Available The article emphasizes the centrality of the concept of work in the thought of the French sociologist Robert Castel. Despite being best known in Brazil for his concepts of social question and social disaffiliation, the concept of work is crucial in the articulation of the author's thought, notably in his latest writing. The article is divided into four parts. First, it provides a general introduction to the work of Castel. Then, it demonstrates how work can be considered the main social question of contemporary global capitalism. Following, it resumes the relationship between work and social vulnerability. The study concludes by pointing out the importance of understanding work as the main contemporary social issue.

  3. The Aspiring Adept: Robert Boyle and His Alchemical Quest (Lawrence M. Principe)

    Science.gov (United States)

    Kovac, Jeffrey

    1999-10-01

    Robert Boyle is widely regarded as the Father of Modern Chemistry, who broke once and for all from the irrational, misguided alchemy that preceded him. One of the goals of this carefully researched and argued new book by Lawrence M. Principe, Assistant Professor in the Department of Chemistry and the Institute for the History of Science, Medicine, and Technology at The Johns Hopkins University, is to refute the two errors in this characterization of Boyle and to understand his life, thought, and work in the intellectual and social context of his time. This book is not for the casual reader; it is a detailed scholarly treatise in the history of science, but it provides a fresh and interesting perspective on Boyle and on the development of chemistry in the 17th century. Boyle is usually characterized as a modern scientist and his most famous book, The Skeptical Chymist, as a critique of traditional alchemy. Principe demonstrates that this characterization is based on a selective and sometimes incorrect reading of Boyle's works. Like Newton, Boyle was deeply involved in traditional transmutational alchemy, reading the works of other alchemists, performing experiments, and even witnessing transmutations. Alchemy, however, was not a monolith and Boyle adhered to what Principe tentatively identifies as a uniquely English school of supernatural alchemy. According to Principe, The Skeptical Chymist was mainly a criticism of the Paracelsians interested in chemical medicine rather than a defense of what we would now regard as modern chemistry. To further support his characterization of Boyle and to better reveal Boyle's involvement in alchemyparticularly the transmutation of base metals to gold, termed chrysopoeiaPrincipe has reconstructed from some 20 fragments one of Boyle's alchemical manuscripts, his Dialogue on the Transmutation of Metals. The full text of this lost work is included as Appendix 1. Two other primary sources, Interview Accounts of Transmutations and

  5. ANTHROPOLOGY AT WAR: ROBERT H. LOWIE AND THE TRANSFORMATION OF THE CULTURE CONCEPT, 1904 to 1954.

    Bargheer, Stefan

    2017-03-01

    The concept of culture used in American anthropology has fundamentally transformed throughout the first half of the twentieth century. The changing resonance of the work of Robert H. Lowie offers revealing insights into this development. Lowie was part of the first generation of students of Franz Boas that highlighted the importance of individual variation for the study of both primitive and civilized societies. Yet, its initial resonance notwithstanding, the culture concept that prevailed in the discipline went into a different direction as the result of anthropologists' involvement in the war effort. It was advanced by the second generation of Boas' students such as Ruth Benedict and Margaret Mead, who stressed the homogeneity of cultures. The contrast highlights the diversity of approaches available within anthropology in the first half of the century and the crucial impact of World War II in determining which of these possibilities became institutionalized in the decades after the war. © 2017 Wiley Periodicals, Inc.

  6. Contemporary Hegelian Scholarship: Robert Stern’s Holistic Reading of Hegel

    2015-12-01

    Full Text Available This is a monographic presentation in which the author depicts the guidelines of Professor Robert Stern’s interpretation of Hegelian Metaphysics by emphasizing in its characteristic holistic reading. The proposal is that some key fundamental topics of Hegelian scholarship will emerge with a clarified understanding after this reading: the concept of Truth and absolute knowledge are reassessed by showing the necessary connection of Epistemology and Metaphysics in Hegel. Hegelian Metaphysics, accordingly, appears ultimately as the principle for a reading of Hegel’s entire philosophy and illuminates its nature of general metaphysical inquiry. Finally, this reading allows drawing on the connection of Hegel’s Idealism with the Pragmatist tradition initiated by Peirce.

    2005-06-01

    Full Text Available Analysing the unpublished correspondence of Robert Lowth, author of A Short Introduction to English Grammar (1762, this article attempts to find evidence of linguistic influence between people belonging to the same social network. Such evidence is used to try and determine where Lowth found the linguistic norm he presented in his grammar. Adding to the data presented by Nevalainen and Raumolin Bmnberg (2003 on the basis of their study of fourteen morphosyntactic items in the Corpus of Early English Correspondence, a detailed analysis is presented of eighteenth-century English. One of the results is an explanation for the presence in Lowth's grammar of the stricture against double negation at a time when double negation was no longer in current use.

  8. Homage to Robert Hooke (1635-1703): new insights from the recently discovered Hooke Folio.

    Gest, Howard

    2009-01-01

    Microorganisms were first observed by Robert Hooke and Antoni van Leeuwenhoek between 1665 and 1678. In 1665, Hooke published Micrographia, which depicted the details of 60 objects as seen in the microscope. One chapter was devoted to the microfungus Mucor, the first microbe observed by the human eye. Leeuwenhoek, despite having no scientific training, became the first to observe protozoa, red blood cells, the sperm cells of animals, and bacteria, which he described in numerous letters to the Royal Society of London. In 1677, Hooke became Secretary of the Royal Society and, in the same year, confirmed some of Leeuwenhoek's discoveries. The discovery in 2006 of more than 650 pages of Hooke's missing records (the "Hooke Folio") allows us to verify the proceedings of Royal Society meetings and promises to be an important new source of Hooke's views on the renaissance of science in the 17th century.

  9. The discovery of microorganisms by Robert Hooke and Antoni Van Leeuwenhoek, fellows of the Royal Society.

    2004-05-01

    The existence of microscopic organisms was discovered during the period 1665-83 by two Fellows of The Royal Society, Robert Hooke and Antoni van Leeuwenhoek. In Micrographia (1665), Hooke presented the first published depiction of a microganism, the microfungus Mucor. Later, Leeuwenhoek observed and described microscopic protozoa and bacteria. These important revelations were made possible by the ingenuity of Hooke and Leeuwenhoek in fabricating and using simple microscopes that magnified objects from about 25-fold to 250-fold. After a lapse of more than 150 years, microscopy became the backbone of our understanding of the roles of microbes in the causation of infectious diseases and the recycling of chemical elements in the biosphere.

  10. CRAFTING THE MICROWORLD: HOW ROBERT HOOKE CONSTRUCTED KNOWLEDGE ABOUT SMALL THINGS.

    Science.gov (United States)

    Lawson, Ian

    2016-03-20

    This paper investigates the way in which Robert Hooke constructed his microscopical observations. His Micrographia is justifiably famous for its detailed engravings, which communicated Hooke's observations of tiny nature to his readers, but less attention has been paid to how he went about making the observations themselves. In this paper I explore the relationship between the materiality of his instrument and the epistemic images he produced. Behind the pictures lies an array of hidden materials, and the craft knowledge it took to manipulate them. By investigating the often counter-theoretical and conflicting practices of his ingenious microscope use, I demonstrate the way in which Hooke crafted the microworld for his readers, giving insight into how early modern microscopy was understood by its practitioners and audience.

    2003-01-01

    Robert A. Rankin, one of the world's foremost authorities on modular forms and a founding editor of The Ramanujan Journal, died on January 27, 2001, at the age of 85. Rankin had broad interests and contributed fundamental papers in a wide variety of areas within number theory, geometry, analysis, and algebra. To commemorate Rankin's life and work, the editors have collected together 25 papers by several eminent mathematicians reflecting Rankin's extensive range of interests within number theory. Many of these papers reflect Rankin's primary focus in modular forms. It is the editors' fervent hope that mathematicians will be stimulated by these papers and gain a greater appreciation for Rankin's contributions to mathematics. This volume would be an inspiration to students and researchers in the areas of number theory and modular forms.

  15. Review: Local Government in England: Centralisation, Autonomy and Control by Colin Corpus, Mark Roberts, Rachel Wall

    Directory of Open Access Journals (Sweden)

    Jonathan Carr-West

    2018-04-01

    Full Text Available Local Government in England: Centralisation, Autonomy and Control is a serious book and an important contribution to the scholarship around local government. It opens however, with a pleasingly comic tableau as academics from England, Portugal and Poland bicker amiably at a conference and on Twitter about whose country is really the most centralised. The rest of the book is devoted to showing why the English academics were right, why it matters and what should be done about it. The main thrust of the text is an analysis of the impact of the dominant policy narratives around centralism and localism. The argument that Copus, Wall and Roberts put forward could be boiled down to the assertion that the problem with local government in England is that it is neither local nor government. But to make this case they first helpfully unpack several sets of concepts that are all too often elided together.

  16. Lessons in power: Lyndon Johnson revealed. A conversation with historian Robert A. Caro.

    Caro, Robert A

    2006-04-01

    No one can lead who does not first acquire power, and no leader can be great who does not know how to use that power. The trouble is that the combination of the two skills is rare. Amassing power requires ambition, a focused pragmatism, and a certain ruthlessness that is often at odds with the daring, idealistic vision needed to achieve great things with that power. The tension is as real in business as it is in politics. This magazine is replete with examples of successful senior managers who could not make the switch from ambitious executive to corporate leader because they did not know what to do with the power they had so expertly accumulated. Robert Caro is a student of power. For the past 27 years, the two-time Pulitzer prize-winning biographer of Robert Moses and Lyndon Johnson has focused on the question of how Johnson amassed and wielded power. Caro's deep understanding of the inner workings of power offers senior executives a nuanced picture of leadership at the highest level. In this wide-ranging conversation, Caro shares his insights about the nature of power, the complexity of ambition, and the role that the greater good can play in the making of a leader. Power doesn't always corrupt, he insists. But what it invariably does is reveal a leader's true nature. "Today, when CEOs have acquired more and more power to change our lives," Caro says,"they have become like presidents in their own right, and they, too, need to align themselves with something greater than themselves if they hope to become truly great leaders."

    Full Text Available David Roberts' views of Córdoba were carried out in 1833 and later redrafted as lithographs, engravings, and oils. These artworks enjoyed great commercial success and international diffusion due to their thematic and undoubted artistic value. The authors analyze their documentary value as a graphic record -prior to the advent of photography- of the urban landscape and architecture of Cordoba, a city now denominated a World Heritage Site. These images are studied here for the first time as a group, since they are either virtually untraceable or dispersed in museums throughout the world. In addition, these views have been contextualized with information concerning the artist and his Spanish journey, including a letter that he wrote from Córdoba. The documentary reliability of every image is also assessed, while the significant transformations of the places represented are indicated.Las vistas realizadas en Córdoba por David Roberts en 1833, reelaboradas como litografías, grabados y óleos, han gozado de gran éxito comercial y difusión internacional por su temática e indudable interés artístico. Esta investigación profundiza en su valor documental como registros gráficos previos a la aparición de la fotografía, del paisaje y la arquitectura de una ciudad hoy considerada Patrimonio de la Humanidad. Las imágenes presentadas se analizan por primera vez como conjunto, pues algunas son de difícil localización o están dispersas en museos de todo el mundo, y se contextualizan con datos sobre el pintor y su viaje por España, considerando una carta que éste escribió desde Córdoba. También se valora la fiabilidad documental de cada vista, a la vez que se detectan significativas transformaciones de los lugares representados.

    to implement use of Roberts' Coping with Labor Algorithm © (CWLA) with laboring women in a large tertiary care facility. this was a quality improvement project to implement an alternate approach to pain assessment during labor. It included system assessment for change readiness, implementation of the algorithm across a 6-week period, evaluation of usefulness by nursing staff, and determination of sustained change at one month. Stakeholder Theory (Friedman and Miles, 2002) and Deming's (1982) Plan-Do-Check-Act Cycle, as adapted by Roberts et al (2010), provided the framework for project implementation. the project was undertaken on a labor and delivery (L&D) unit of a large tertiary care facility in a southwestern state in the USA. The unit had 19 suites with close to 6000 laboring patients each year. full, part-time, and per diem Registered Nurse (RN) staff (N=80), including a subset (n=18) who served as the pilot group and champions for implementing the change. a majority of RNs held a positive attitude toward use of the CWLA to assess laboring women's coping with the pain of labor as compared to a Numeric Rating Scale (NRS). RNs reported usefulness in using the CWLA with patients from a wide variety of ethnicities. A pre-existing well-developed team which advocated for evidence-based practice on the unit proved to be a significant strength which promoted rapid change in practice. this work provides important knowledge supporting use of the CWLA in a large tertiary care facility and an approach for effectively implementing that change. Strengths identified in this project contributed to rapid implementation and could be emulated in other facilities. Participant reports support usefulness of the CWLA with patients of varied ethnicity. Assessment of change sustainability at 1 and 6 months demonstrated widespread use of the algorithm though long-term determination is yet needed. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2014-01-01

    We study the link between observed ultraviolet (UV) luminosity, stellar mass and dust attenuation within rest-frame UV-selected samples at z ˜ 4, ˜ 3 and ˜1.5. We measure by stacking at 250, 350 and 500 μm in the Herschel/Spectral and Photometric Imaging Receiver images from the Herschel Multi-Tiered Extragalactic Survey (HerMES) program the average infrared luminosity as a function of stellar mass and UV luminosity. We find that dust attenuation is mostly correlated with stellar mass. There is also a secondary dependence with UV luminosity: at a given UV luminosity, dust attenuation increases with stellar mass, while at a given stellar mass it decreases with UV luminosity. We provide new empirical recipes to correct for dust attenuation given the observed UV luminosity and the stellar mass. Our results also enable us to put new constraints on the average relation between star formation rate (SFR) and stellar mass at z ˜ 4, ˜3 and ˜1.5. The SFR-stellar mass relations are well described by power laws (SFR∝ M_*^{0.7}), with the amplitudes being similar at z ˜ 4 and ˜3, and decreasing by a factor of 4 at z ˜ 1.5 at a given stellar mass. We further investigate the evolution with redshift of the specific SFR. Our results are in the upper range of previous measurements, in particular at z ˜ 3, and are consistent with a plateau at 3 < z < 4. Current model predictions (either analytic, semi-analytic or hydrodynamic) are inconsistent with these values, as they yield lower predictions than the observations in the redshift range we explore. We use these results to discuss the star formation histories of galaxies in the framework of the main sequence of star-forming galaxies. Our results suggest that galaxies at high redshift (2.5 < z < 4) stay around 1 Gyr on the main sequence. With decreasing redshift, this time increases such that z = 1 main-sequence galaxies with 108

Though fluently used in infamous works such as “The Iliad”, honor has yet to be so explicitly dissected until now. Dr. Oprisko’s book takes a promiscuous and brutally honest approach to “Honor” en generale as well as the many facets associated with such. Similar to fine cuisine and wine, there are many literary accompaniments that serve as wonderful pairings to broaden the kaleidoscope perspectives presented in the book. The contested novel by J.D. Salinger, “The Catcher in the Rye”, although by no means consists of any political or metaphysical theory, contains a stark personification of what is actively presented in every chapter of Dr. Oprisko’s book. Holden Caufield serves as a terrific litmus test for the concepts defined in Oprisko’s work. Holden is by no means a likeable character in the literary world, but however he is raw enough to be able to internalize and beholden things like, “honorableness”, “dignity”, and most importantly for Holden, “face”. Though to the naked eye and untrained mind these “things” which Holden can in fact internalize may seem fairly simple; it challenges the reader to humble oneself and accept that which is the raw. There is no space for semantics and lies in Oprisko’s work. In fact it is so shockingly explicit, one may find themselves utterly offended. Holden Caufield offended readers for years after Sallinger brought him to life over the span of 200 or more so pages, so much that the book was condemned in certain places. Robert L. Oprisko’s, “Honor: A Phenomenology”, in my utmost opinion, contains this same potential. By critically engaging in Oprisko’s spar with “honor”, one may find themselves

    Particle physics really began as an independent scientific discipline after the Second World War. Robert Marshak was one of its pioneers on the theoretical front, starting out his career with important contributions on meson theory (together with Hans Bethe). The life of Marshak, who died in December 1992, was intimately interwoven with the post-war development of particle physics. His work on weak interaction theory was an important step towards the formulation of the V-A theory, the main pillar on which the modern electroweak theory rests erected. He is also remembered as the founder of the biennial 'Rochester' conference series (March 1993, page 24). Just before his death Robert Marshak finished writing his book on the concepts of particle physics. The book starts out with an historical account of the development of the field. He divides it into the startup period (1945-60) - the period of meson physics, the physics of strange particles, parity violation etc; the heroic period (1960-1975) when the Standard Model of the electroweak and strong interactions was developed; and finally the period of consolidation and speculation (since 1975). Marshak's recollection of the development of particle physics represents a personal view, worth reading by young researchers, although it does not attempt to provide a complete picture. After the historical chapter Marshak introduces the reader to the basics of quantum field theory (space-time symmetries, global internal symmetries and their breaking, gauge symmetries). Later he turns to a description of QCD and the gauge theory of the electroweak interactions. A whole chapter is devoted to the problems related to anomalies. In the last part of the book Marshak discusses various hypotheses of unifying the strong and electroweak interactions, especially the various facets of the SO(10) theory, followed by a long discussion of the fermion generation problem and of preon models. The book concludes with an extensive

    Managing diversity dynamics in academic or clinical settings for men in nursing has unique challenges resulting from their minority status within the profession. The purpose of this study was to share challenges and lessons learned identified by male scholars in the Robert Wood Johnson Foundation Nurse Faculty Scholars program and suggest strategies for creating positive organizations promoting inclusive excellence. Multiple strategies including informal mentored discussions and peer-to-peer dialogue throughout the program, formal online surveys of scholars and National Advisory Committee members, and review of scholar progress reports were analyzed as part of the comprehensive evaluation plan of the program. Diversity dynamic issues include concerns with negative stereotyping, microaggression, gender intelligence, and differences in communication and leadership styles. Male nurse faculty scholars report experiencing both opportunities and challenges residing in a predominately female profession. This article attempts to raise awareness and suggest strategies to manage diversity dynamics in service of promoting the development of a culture of health that values diversity and inclusive excellence for both men and women in academic, research, and practice contexts.

    Full Text Available In April 2016, 'The Guardian' published ‘Generation Anthropocene: How humans have altered the planet forever’ by the celebrated academic and nature writer Robert Macfarlane. Reflecting on the article’s importance as a critical experiment and, perhaps, a vital form of public engagement, Contemporary Studies Network (CSN asked six of its members, working across very different areas of literary and cultural studies, to respond to and extend Macfarlane’s article, mapping the different ways in which literary scholars might approach the age of the Anthropocene. Conducted via email, this roundtable conversation asks to what extent the Anthropocene marks a new era in literary criticism, how exactly it extends preexisting strands of ecocriticism and trauma studies, and what the global scope of the term might be beyond the confines of the Western literary canon. Discussion ranges from issues of temporality to genre and form and it also addresses Macfarlane’s rhetoric, his call to arms for those working in the humanities, for a more comprehensive investigation in to the roles of literature and art in responding to and representing what may become a new epoch.

    Robert FitzRoy, Captain of HMS Beagle and second governor of New Zealand, has two contradictory reputations among modern academics. Evolutionary biologists and Darwin scholars generally view FitzRoy as a supporter of slavery, famously quarrelling with the abolitionist Darwin over that topic during a Brazilian stopover early in the voyage of HMS Beagle. He is also regarded as a political and religious reactionary, taking a biblically creationist position at the infamous 1860 Oxford meeting of the British Association for the Advancement of Science. New Zealand historians, however, view his record as governor much more positively. They emphasize that FitzRoy was wildly unpopular with the British settlers because of his enlightened insistence that the native Maori should be treated fairly. We outline the history of these seemingly inconsistent views and examine the evidence for each. We conclude by suggesting that a more nuanced account of FitzRoy's career would surely be more thought-provoking as well as respectful of the facts.

    2013-01-01

    Kathleen Kaska has done a remarkable job of capturing the life of Robert Porter Allen, truly one of the premier biologist/conservationists of the twentieth century. Allen, born in 1905, grew up reading outdoor adventure books and playing in the woods of northern Pennsylvania with his brother. At a young age, he was encouraged to join the Junior Audubon club and his passion for ornithology soon crystallized. He attended Lafayette College to study ornithology, but he was disinterested in academics and fared poorly. He dropped out after two years and joined the Merchant Marines. Not an auspicious beginning for such a highly respected scientist and conservationist! Soon, however, he landed a librarian job with Audubon and his diligence, acumen, and communication skills allowed him to take more and more responsibilities. He became one of the youngest Audubon sanctuary directors ever appointed, and he was also able to secure a fellowship through Cornell to work on Roseate Spoonbills (Platalea ajaja). Audubon later appointed him to lead their Whooping Crane (Grus americana) studies.

    Full Text Available In the 1850s Robert William Plant collected plants and other natural specimens in what is now KwaZulu-Natal. This one-time Englishman compiled a dictionary for gardeners before emigrating to Natal in 1850. There he worked as the agent for Samuel Stevens, the London dealer in ‘curiosities of natural history’. Though Plant collected mainly plants, he also sent consignments of beetles, butterflies, bird skins and shells back to Britain. He published the first scientific paper on Zululand and was requested by the Royal Botanic Gardens at Kew to write the first Flora natalensis. It was while collecting for this never-to-be-completed treatise that Plant contracted malaria in Maputaland. He died in St Lucia in 1858 and in doing so became South Africa’s martyr to botany. What emerges from this study is a picture of the difficulties faced by plant hunters in mid-19th-century South Africa, the sort of plants they collected and the necessity for them sometimes to diversify into other natural history products to survive.

  14. A capital Scot: microscopes and museums in Robert E. Grant's zoology (1815-1840).

    2016-06-01

    Early nineteenth-century zoology in Britain has been characterized as determined by the ideological concerns of its proponents. Taking the zoologist Robert E. Grant as an exemplary figure in this regard, this article offers a differently nuanced account of the conditions under which natural-philosophical knowledge concerning animal life was established in post-Napoleonic Britain. Whilst acknowledging the ideological import of concepts such as force and law, it points to an additional set of concerns amongst natural philosophers - that of appropriate tool use in investigation. Grant's studies in his native Edinburgh relied heavily on the use of microscopes. On his arrival in London, however, he entered a culture in which a different set of objects - museum specimens - held greater persuasive power. This article relates changes in Grant's ideas and practices to the uneven emphases on microscopic and museological evidence amongst European, Scottish and English natural philosophers at this time. In so doing, it identifies the reliance of London-based natural philosophers on museology as constituting a limiting effect on the kinds of claim that Grant sought to make regarding the nature of life.

    Roberts syndrome and SC phocomelia (RBS/SC) are genetic autosomal recessive syndromes caused by establishment of cohesion 1 homolog 2 ( ESCO 2) mutation. RBS/SC appear to have a variety of clinical features, even with the same mutation of the ESCO2 gene. Here, we established and genetically characterized a medaka model of RBS/SC by reverse genetics. The RBS/SC model was screened from a mutant medaka library produced by the Targeting Induced Local Lesions in Genomes method. The medaka mutant carrying the homozygous mutation at R80S in the conserved region of ESCO2 exhibited clinical variety (i.e. developmental arrest with craniofacial and chromosomal abnormalities and embryonic lethality) as characterized in RBS/SC. Moreover, widespread apoptosis and downregulation of some gene expression, including notch1a, were detected in the R80S mutant. The R80S mutant is the animal model for RBS/SC and a valuable resource that provides the opportunity to extend knowledge of ESCO2. Downregulation of some gene expression in the R80S mutant is an important clue explaining non-correlation between genotype and phenotype in RBS/SC. © 2012 The Authors Development, Growth & Differentiation © 2012 Japanese Society of Developmental Biologists.

    2013-02-01

    Full Text Available This article explored the relation between creation and salvation as acts of God in the theology of Robert Jenson, an American Lutheran theologian. This is important due to Jenson’s growing importance as theologian and because of the current importance of ecotheology (and related themes that were implicated by the relation between creation and salvation. Jenson’s theology is an effort to tell God’s particular story and it can be described as a Trinitarian, narrative and eschatological theology. His starting point is that God’s eternity must not be understood as timeless (this is unbiblical and incompatible with the story of creation and redemption and that creation (space and time takes place somehow within the being of God. Jenson qualified this ‘withinness’, but also emphasised that creation is an intelligible whole, a history with an intended end. It is important for him that God’s story – a story of dramatic coherence – is not separated from our own and creation’s story. Within this understanding of God’s story (as dramatic coherence, creation found its own dramatic teleology because salvation also includes creation. Creation is therefore not subjected to pointlessness any longer, but will find its final place within God. The implication of this is that we must value creation much more and act with more responsibility towards it. According to Jenson we must enjoy creation in an aesthetic fashion and delight in creation as a whole because of its dramatic teleology.

    2015-04-01

    TRANSCENDENCE explores aspects of Einstein's life and his general theory of relativity at the time of the theory's creation and initial reception. While being faithful to historical scholarship, the play creates its own theatrical reality aiming to engage emotions and intellect. Those who strive for transcendence must nevertheless also confront the harsh realities of living in specific time-bound social contexts. Universal constants that anchor physical theory in an objective reality, as Einstein believed, do not readily have equivalents in notions of identity, duty, loyalty, and excellence. In November 1915 after toiling for years in Zurich, Prague, and now Berlin, Einstein achieved his general theory of relativity. When in 1919 British astronomers announced evidence for the bending of starlight by the sun as Einstein had predicted, he soon surprisingly found himself an international celebrity. Expectations arose that he would be called to Stockholm. But the Nobel Committee for Physics refused to acknowledge ``speculations'' such Einstein's. The dismissal of relativity entailed principled and biased opposition, and not simply mistakes in evaluation. Several committee members agreed that Einstein must not receive a Prize. Join us for a dramatic staged reading of TRANSCENDENCE, a play by the science historian Robert Marc Friedman (http://www.hf.uio.no/iakh/english/people/aca/robertfr/index.html) and directed by James Glossman, Lecturer in Directing and Shakespeare, Johns Hopkins University. After the performance, the playwright, director and actors will be available for a talk-back audience discussion.

  18. Diagnostic Overlap between Fanconi Anemia and the Cohesinopathies: Roberts Syndrome and Warsaw Breakage Syndrome

    2010-01-01

    Full Text Available Fanconi anemia (FA is a recessively inherited disease characterized by multiple symptoms including growth retardation, skeletal abnormalities, and bone marrow failure. The FA diagnosis is complicated due to the fact that the clinical manifestations are both diverse and variable. A chromosomal breakage test using a DNA cross-linking agent, in which cells from an FA patient typically exhibit an extraordinarily sensitive response, has been considered the gold standard for the ultimate diagnosis of FA. In the majority of FA patients the test results are unambiguous, although in some cases the presence of hematopoietic mosaicism may complicate interpretation of the data. However, some diagnostic overlap with other syndromes has previously been noted in cases with Nijmegen breakage syndrome. Here we present results showing that misdiagnosis may also occur with patients suffering from two of the three currently known cohesinopathies, that is, Roberts syndrome (RBS and Warsaw breakage syndrome (WABS. This complication may be avoided by scoring metaphase chromosomes—in addition to chromosomal breakage—for spontaneously occurring premature centromere division, which is characteristic for RBS and WABS, but not for FA.

    Robert Huber and his colleagues, Johann Deisenhofer and Hartmut Michel, elucidated the three-dimensional structure of the Rhodopseudomonas viridis photosynthetic reaction center. This membrane protein complex is a basic component of photosynthesis - a process fundamental to life on Earth - and for their work, Huber and his colleagues received the 1988 Nobel Prize in Chemistry. Because structural information is central to understanding virtually any biological process, Huber likens their discovery to "switching on the light" for scientists trying to understand photosynthesis. Huber marvels at the growth of structural biology since the time he entered the field, when crystallographers worked with hand-made instruments and primitive computers, and only "a handful" of crystallographers would meet annually in the Bavarian Alps. In the "explosion" of structural biology since his early days of research, Huber looks to the rising generation of scientists to solve the remaining mysteries in the field - such as the mechanisms that underlie protein folding. A strong proponent of science mentorship, Huber delights in meeting young researchers at the annual Nobel Laureate Meetings in Lindau, Germany. He hopes that among these young scientists is an "Einstein of biology" who, he says with a twinkle in his eye, "doesn't know it yet." The interview was conducted by JoVE co-founder Klaus J. Korak at the Lindau Nobel Laureate Meeting 2008 in Lindau, Germany.

    The history of psychosurgery is filled with tales of researchers pushing the boundaries of science and ethics. These stories often create a dark historical framework for some of the most important medical and surgical advancements. Dr. Robert G. Heath, a board-certified neurologist, psychiatrist, and psychoanalyst, holds a debated position within this framework and is most notably remembered for his research on schizophrenia. Dr. Heath was one of the first physicians to implant electrodes in deep cortical structures as a psychosurgical intervention. He used electrical stimulation in an attempt to cure patients with schizophrenia and as a method of conversion therapy in a homosexual man. This research was highly controversial, even prior to the implementation of current ethics standards for clinical research and often goes unmentioned within the historical narrative of deep brain stimulation (DBS). While distinction between the modern practice of DBS and its controversial origins is necessary, it is important to examine Dr. Heath's work as it allows for reflection on current neurosurgical practices and questioning the ethical implication of these advancements.

    Robert H. Siemann originally conceived of the Advanced Accelerator Research Department (AARD) as an academic, experimental group dedicated to probing the technical limitations of accelerators while providing excellent educational opportunities for young scientists. The early years of the Accelerator Research Department B, as it was then known, were dedicated to a wealth of mostly student-led experiments to examine the promise of advanced accelerator techniques. High-gradient techniques including millimeter-wave rf acceleration, beam-driven plasma acceleration, and direct laser acceleration were pursued, including tests of materials under rf pulsed heating and short-pulse laser radiation, to establish the ultimate limitations on gradient. As the department and program grew, so did the motivation to found an accelerator research center that brought experimentalists together in a test facility environment to conduct a broad range of experiments. The Final Focus Test Beam and later the Next Linear Collider Test Accelerator provided unique experimental facilities for AARD staff and collaborators to carry out advanced accelerator experiments. Throughout the evolution of this dynamic program, Bob maintained a department atmosphere and culture more reminiscent of a university research group than a national laboratory department. His exceptional ability to balance multiple roles as scientist, professor, and administrator enabled the creation and preservation of an environment that fostered technical innovation and scholarship.

Based on Monir Moniruzzaman’s ethnographic research on the illicit organ trade, Spare Parts explores the ethics of organ trafficking and the emergence of bodily inequality in times of transplant tinkering. In this installation, the viewer is confronted with life sized video projections of Rahim Sheikh, a Bangladeshi kidney seller and Robert Zurrer, a Canadian kidney transplant recipient/buyer, whose kidneys were commodified in the marketplace. The video projections are installed so that the individuals sit in silence facing each other.  Spare Parts highlights the intimacy of spare parts, the economy of the global marketplace, the perils of techno-medicine, and what is means to be human in the 21st century. The installation captures that the buying and selling of body parts is not just a market transaction, but rather represents the desperation, dis/connection, and inequality that exists in the trade.

    Robert Graves is a poet-mythographer, well-known in the U. K. and the U. S. A., but not in Japan despite his huge amount of poetic, mythographical, prose and critical works. Furthermore, even in the U. S. A. and the U. K., some people have been shunning him politely as a versatile iconoclast possessed of the White Goddess. In fact, it is not difficult to imagine that when King Jesus, a life story of Christ, was published, people were shocked at his extraordinary mythographical Christology derived from his enthusiasm towards the White Goddess Cult. In Christ he discovered the fragments of maternal doctrine as a new concept in opposition to the Apollonian theory of Judaism, but they seemed to be quite incomplete in the author's eyes lacking in something most essential in life, recognition of love and hatred discipline. This paper is an inquiry into how the author developed his own hermaneutics of Christ through his wide and thorough scholarship on mythology, history, the Bible and Celtic poetry.

    The Robert Wood Johnson Foundation Nurse Faculty Scholars program was created to address the nursing faculty shortage and thereby decrease the nursing shortage. The purpose of the study was to describe the program development, implementation, and ongoing outcome evaluation. Data on scholarly productivity, impact of research, research funding, and leadership positions were compiled, including an h-index (impact of publications) comparison with a comparison group of other interdisciplinary faculty at the same institutions of the 90 current and alumni scholars. There is evidence of the achievements of the individual scholars; however, the effect of the synergy of the multiple components of the program is difficult to capture in traditional evaluation strategies. The sense of possibility and responsibility (to the profession, to improving the health of all Americans, and to one's school of nursing and university) was a significant outcome of the program. Lessons learned from the program are important for the leadership development and retention of nursing faculty. Copyright © 2017 Elsevier Inc. All rights reserved.

    2010-12-01

    The paper attempts to reconstruct the proto-cybernetic concept of regulation which emerged in early 20th century both in biology and psychology, and was critically reflected in literature. The basic premise is that Kurt Lewin's field-theoretical psychology played a crucial role in the development of behavioral self-regulation concepts. The goal is to show (1) that Lewin's early experiments and theories were based on the idea of a dynamic process of self-regulation determined by the actors and their personal motivation and interaction, (2) that this concept of self-regulation functioned as a camouflage for power-strategies that aimed to regulate and optimize the economic production and social reproduction processes, (3) that in Robert Musil's fragmentary, 'fringing' novel The Man without Qualities the attempt to optimize the social and economic behavior and to establish a homeostatic state proved to be a complete failure. As a notable result, this 'literary test' of behavioral self-regulation revealed the violence and imbalance of power inherent in this concept of self-regulation and its practical implementation.

    The Robert Wood Johnson (RWJ) Foundation initiated Turning Point in collaboration with the W.K. Kellogg Foundation (Kellogg) in 1997. The purpose of this major national initiative was to strengthen the public health infrastructure in the United States so that states, local communities, and their public health agencies might respond to the challenge to protect and improve the public's health in the 21st century. RWJ funded 21 states and Kellogg funded 43 communities to work together to create a new way of thinking about how health could be improved and who should be involved. Although the ultimate outcome was to improve health, both foundations expected diverse partnerships to work together to create strategic health improvement plans at both the community and state levels. The foundations funded a variety of strategies within those health improvement plans during an implementation phase. The premise in funding partnerships, as opposed to a single entity, was that effective public health systems would be developed best through a shared responsibility (including the private sector) for the health of a community.

    To analyze the prevalence, cause, treatment, and risk factors of severe post-partum hemorrhage (transfusion, surgery, radiology) observed at the maternity ward of the Robert-Debré Hospital, Paris. Method. This retrospective cohort was collected from a database including 19182 deliveries from 1992 to 1998. The entire medical file was reviewed in cases of severe hemorrhage. The prevalence of severe post-partum hemorrhage was 23 per 10,000 deliveries (44 patients). Transfusion was performed in 44/44 and hysterectomy in 3/44. Three patients were transferred to the intensive care unit. There were no deaths. At multivariate analysis, risk factors for severe post-partum hemorrhage were: abnormal placental insertion (OR=7.2; 95CI: 2.18-18.3), cesarean (OR=5.8; 95CI: 2.9-11.6), multiple pregnancy (OR=3.2; 95CI: 1.3-7.8), prematurity (OR=3, 95CI: 1.5-6.2), hypertension (OR=2.9; 95CI: 1.3-6.3). Twenty-six percent of the patients had no risk factors. The prevalence of severe pot-partum hemorrhage is low in our experience. The methodology used for this retrospective cohort does not enable an explanation. Intensive obstetrical care is necessary in case of abnormal placenta insertion. In 10 out of 44 cases, severe post-partum hemorrhage occurred in a context of insufficient monitoring, late or erroneous diagnosis, or incorrect treatment.

    2017-06-01

    The experimental study of gravity became much more active in the late 1950s, a change pronounced enough be termed the birth, or naissance, of experimental gravity physics. I present a review of developments in this subject since 1915, through the broad range of new approaches that commenced in the late 1950s, and up to the transition of experimental gravity physics to what might be termed a normal and accepted part of physical science in the late 1960s. This review shows the importance of advances in technology, here as in all branches of natural science. The role of contingency is illustrated by Robert Dicke's decision in the mid-1950s to change directions in mid-career, to lead a research group dedicated to the experimental study of gravity. The review also shows the power of nonempirical evidence. Some in the 1950s felt that general relativity theory is so logically sound as to be scarcely worth the testing. But Dicke and others argued that a poorly tested theory is only that, and that other nonempirical arguments, based on Mach's Principle and Dirac's Large Numbers hypothesis, suggested it would be worth looking for a better theory of gravity. I conclude by offering lessons from this history, some peculiar to the study of gravity physics during the naissance, some of more general relevance. The central lesson, which is familiar but not always well advertised, is that physical theories can be empirically established, sometimes with surprising results.

Siemann originally conceived of the Advanced Accelerator Research Department (AARD) as an academic, experimental group dedicated to probing the technical limitations of accelerators while providing excellent educational opportunities for young scientists. The early years of the Accelerator Research Department B, as it was then known, were dedicated to a wealth of mostly student-led experiments to examine the promise of advanced accelerator techniques. High-gradient techniques including millimeter-wave rf acceleration, beam-driven plasma acceleration, and direct laser acceleration were pursued, including tests of materials under rf pulsed heating and short-pulse laser radiation, to establish the ultimate limitations on gradient. As the department and program grew, so did the motivation to found an accelerator research center that brought experimentalists together in a test facility environment to conduct a broad range of experiments. The Final Focus Test Beam and later the Next Linear Collider Test Accelerator provided unique experimental facilities for AARD staff and collaborators to carry out advanced accelerator experiments. Throughout the evolution of this dynamic program, Bob maintained a department atmosphere and culture more reminiscent of a university research group than a national laboratory department. His exceptional ability to balance multiple roles as scientist, professor, and administrator enabled the creation and preservation of an environment that fostered technical innovation and scholarship.

    Transdermal drug delivery continues to provide an advantageous route of drug administration over injections. While the number of drugs delivered by passive transdermal patches has increased over the years, no macromolecule is currently delivered by the transdermal route. Substantial research efforts have been dedicated by a large number of researchers representing varied disciplines including biology, chemistry, pharmaceutics and engineering to understand, model and overcome the skin's barrier properties. This article focuses on engineering contributions to the field of transdermal drug delivery. The article pays tribute to Prof. Robert Langer, who pioneered the engineering approach towards transdermal drug delivery. Over a period spanning nearly 25 years since his first publication in the field of transdermal drug delivery, Bob Langer has deeply impacted the field by quantitative analysis and innovative engineering. At the same time, he has inspired several generations of engineers by collaborations and mentorship. His scientific insights, innovative technologies, translational efforts and dedicated mentorship have transformed the field. © 2013 S. Karger AG, Basel.

  12. The dilemmas of indefiniteness: Utopia, fluidity and subjectivity in Stone, by Adam Roberts

    2017-06-01

    Full Text Available http://dx.doi.org/10.5007/2175-8026.2017v70n2p107 Ae, the narrator-protagonist of the novel Stone, by Adam Roberts, is the only criminal in a post-human utopian society in which the use of nanotechnology has allowed humanity to reach its plenitude. Isolated from the rest of society, one day Ae is offered freedom and wealth if he agrees to kill the population of a whole planet. After accepting this offer, Ae must try to fulfil his mission at the same time that he questions himself and tries to discover who his employers are. In developing the conflict between this deviant individual and the utopia in which he lives, Stone examines the limits of the utopia itself, which is based on the idea of flux and indefiniteness. The novel also explores the models of subjectivity created in the context of this utopia. The notion of utopia as a well-defined social project is replaced by the image of utopian bodies, influenced by technologies that challenge the definitions of the human and of the post-human. In establishing this network of tensions and indefiniteness, the novel offers the possibility that the marginalized sociopath might be the only one capable of examining in depth the reality of a world anesthetized by its own comfort.

  15. Robert Hare's Theory of Galvanism: A Study of Heat and Electricity in Early Nineteenth-Century American Chemistry.

    Science.gov (United States)

    Fisher, Amy

    2018-04-09

    As a professor of chemistry at the University of Pennsylvania, Robert Hare actively shaped early American science. He participated in a large network of scholars, including Joseph Henry, François Arago, and Jacob Berzelius, and experimented with and wrote extensively about electricity and its associated chemical and thermal phenomena. In the early nineteenth century, prominent chemists such as Berzelius and Humphry Davy proclaimed that a revolution had occurred in chemistry through electrical research. Examining Robert Hare's contributions to this discourse, this paper analyzes how Hare's study of electricity and the caloric theory of heat led him to propose a new theory of galvanism. It also examines the reception of Hare's work in America and Great Britain, highlighting the contributions of early American chemists to the development of electrochemistry.

    The reproduction of a San Joaquin kit fox population (Vulpes velox macrotis) was investigated at Camp Roberts Army National Guard Training Site, California, from November 1988 through September 1991. Of 38 vixens radiocollared prior to parturition, 12 (32%) were successful in raising pups from conception to the point where pups were observed above ground. No yearling vixens were known tb be reproductively active. The mean litter size during 1989 - 1991 was 3.0 (n = 21, SE = 0.28) and ranged from one to six pups. Both the proportion of vixens successfully raising pups and the mean litter size observed at Camp Roberts during this study were lower than those reported at other locations. Sex ratios of kit fox pups were male biased two of the three years, but did not differ statistically from 1:1 throughout the study. Whelping was estimated to occur between February 15 and March 5. Results of this study support previous reports that kit foxes are primarily monogamous, although one case of polygamy may have occurred. Both the proportion of dispersing radiocollared juveniles (26%) and the mean dispersal distance (5.9 km) of juveniles at Camp Roberts appeared low compared to other locations

    Full Text Available This paper has developed out of a larger work in progress, which focuses on representations of Italy in contemporary Australian fiction and non-fiction prose. This larger project aims to add to an established body of work on travel writing by considering Australian texts that describe Australian travel in Italy, Italian people and Italian places. In this paper, I will specifically focus on the representations of Italy in Robert Dessaix’s novel Night Letters (1996. My paper will explore the relationship between the writer’s actual journey in Italy and that of the creative work’s main character. The novel offers the protagonist’s account in the form of letters, which describe his travel from Switzerland across Northern Italy to Venice. I will begin by briefly outlining the Italian itinerary followed by Dessaix that would eventually inspire the novel. I will then explore the relationship between Dessaix’s notebooks recording his two journeys in Italy and the literary accomplishment of Night Letters. My aim is to show ways in which an itinerary becomes a story, a complex narrative. Reference will be made to factual accounts and descriptions in the author’s own diaries with an analysis of their generative role as key sources for the fictional work. This will be done through a close reading of particular passages, in the diaries and in the novel, concerning the same event. A comparative analysis of the notebooks and Night Letters can show that Dessaix’s diary entries relating to Italian places are woven into the fictional fabric of the ‘night letters’ according to a unifying principle.

    The Robert Wood Johnson Foundation Nurse Faculty Scholars (RWJF NFS) program was developed to enhance the career trajectory of young nursing faculty and to train the next generation of nurse scholars. Although there are publications that describe the RWJF NFS, no evaluative reports have been published. The purpose of this study was to evaluate the first three cohorts (n = 42 scholars) of the RWJF NFS program. A descriptive research design was used. Data were derived from quarterly and annual reports, and a questionnaire (seven open-ended questions) was administered via Survey Monkey Inc. (Palo Alto, CA, USA). During their tenure, scholars had on average six to seven articles published, were teaching/mentoring at the graduate level (93%), and holding leadership positions at their academic institutions (100%). Eleven scholars (26%) achieved fellowship in the American Academy of Nursing, one of the highest nursing honors. The average ratings on a Likert scale of 1 (not at all supportive) to 10 (extremely supportive) of whether or not RWJF had helped scholars achieve their goals in teaching, service, research, and leadership were 7.7, 8.0, 9.4, and 9.5, respectively. The majority of scholars reported a positive, supportive relationship with their primary nursing and research mentors; although, several scholars noted challenges in connecting for meetings or telephone calls with their national nursing mentors. These initial results of the RWJF NFS program highlight the success of the program in meeting its overall goal-preparing the next generation of nursing academic scholars for leadership in the profession.

  1. Inactivating mutations in ESCO2 cause SC phocomelia and Roberts syndrome: no phenotype-genotype correlation.

    The rare, autosomal recessive Roberts syndrome (RBS) is characterized by tetraphocomelia, profound growth deficiency of prenatal onset, craniofacial anomalies, microcephaly, and mental deficiency. SC phocomelia (SC) has a milder phenotype, with a lesser degree of limb reduction and with survival to adulthood. Since heterochromatin repulsion (HR) is characteristic for both disorders and is not complemented in somatic-cell hybrids, it has been hypothesized that the disorders are allelic. Recently, mutations in ESCO2 (establishment of cohesion 1 homolog 2) on 8p21.1 have been reported in RBS. To determine whether ESCO2 mutations are also responsible for SC, we studied three families with SC and two families in which variable degrees of limb and craniofacial abnormalities, detected by fetal ultrasound, led to pregnancy terminations. All cases were positive for HR. We identified seven novel mutations in exons 3-8 of ESCO2. In two families, affected individuals were homozygous--for a 5-nucleotide deletion in one family and a splice-site mutation in the other. In three nonconsanguineous families, probands were compound heterozygous for a single-nucleotide insertion or deletion, a nonsense mutation, or a splice-site mutation. Abnormal splice products were characterized at the RNA level. Since only protein-truncating mutations were identified, regardless of clinical severity, we conclude that genotype does not predict phenotype. Having established that RBS and SC are caused by mutations in the same gene, we delineated the clinical phenotype of the tetraphocomelia spectrum that is associated with HR and ESCO2 mutations and differentiated it from other types of phocomelia that are negative for HR.

  3. Projecting Dynastic Majesty: State Ceremony in the Reign of Robert Bruce

    2015-07-01

    Full Text Available Following the murder of his rival John Comyn on 10 February at Greyfriars in Dumfries, and the crisis this act incited, Robert the Bruce’s inaugural ceremony took place at Scone in late March 1306. Much about this ceremony is speculative; however, subsequent retrospective legitimisation of the Bruce claims to the royal succession would suggest that all possible means by which Robert’s inauguration could emulate his Canmore predecessors and outline his right to rule on a level playing field with his contemporaries were amplified, particularly where they served the common purpose of legitimising Robert’s highly questioned hold on power. Fourteenth-century Scottish history is inextricably entwined in the Wars of Independence, civil strife and an accelerated struggle for autonomous rule and independence. The historiography of this period is unsurprisingly heavily dominated by such themes and, while this has been offset by works exploring subjects such as the tomb of Bruce and the piety of the Bruce dynasty, the ceremonial history of this era remains firmly in the shadows. This paper will address three key ceremonies through which a king would, traditionally, make powerful statements of royal authority: the inauguration or coronation of Bruce; the marriage of his infant son to the English princess Joan of the Tower in 1328, and his extravagant funeral ceremony in 1329. By focusing thus this paper hopes to shed new light on the ‘dark and drublie days’ of fourteenth-century Scotland and reveal that glory, dynastic majesty and pleasure were as central to the Scottish monarchy in this era as war and political turbulence.

    Full Text Available Robert Seymour was celebrated enough in his day to become one of very few late Regency and early Victorian comic and satirical draughtsmen sufficiently visible to be traced through the magazines of the 1830s. His periodical contributions are, therefore, of considerable significance in trying to establish the patterns of work and maps of interconnected activity that were necessary to sustain the career of a jobbing draughtsman at this time. After contributing to Bell’s Life in London in the late 1820s, Seymour’s presence as a prolific magazine illustrator dates largely from the early 1830s. As well as a mass of jobbing illustrations that were produced for a remarkably diverse range of magazines. Seymour worked extensively for three significant and profusely illustrated magazines at this time — the Looking Glass, Figaro in London, and the Comic Magazine. The Looking Glass was published by Thomas McLean and sought to sustain an established tradition of political caricature through adapting it to a magazine format using the relatively new reprographic medium of lithography. Figaro in London was illustrated by vignette wood engravings, which were both vernacular and sophisticated at the same time. The Comic Magazine, another publication dependent on small wood-engraved images, sought to build on the growing popularity of song books and comic annuals. The diversity and prolixity of Seymour’s output at this time bears testimony to the extraordinary demands made on draughtsmen and engravers in the 1830s, and suggests something of the relentlessly innovative market place for humorous and satirical print at this time.

  5. An experimental 'Life' for an experimental life: Richard Waller's biography of Robert Hooke (1705).

    2016-03-01

    Richard Waller's 'Life of Dr Robert Hooke', prefixed to his edition of Hooke's Posthumous Works (1705), is an important source for the life of one of the most eminent members of the early Royal Society. It also has the distinction of being one of the earliest biographies of a man of science to be published in English. I argue that it is in fact the first biography to embrace the subject's natural-philosophical work as the centre of his life, and I investigate Waller's reasons for adopting this strategy and his struggle with the problem of how to represent an early experimental philosopher in print. I suggest that Waller eschews the 'Christian philosopher' tradition of contemporary biography - partly because of the unusually diverse and fragmentary nature of Hooke's intellectual output - and draws instead upon the structure of the Royal Society's archive as a means of organizing and understanding Hooke's life. The most quoted phrase from Waller's biography is that Hooke became 'to a crime close and reserved' in later life; this essay argues that Waller's biographical sketch was fashioned in order to undo the effects of that reserve. In modelling his approach very closely on the structure of the society's records he was principally concerned with making Hooke's work and biography accessible, intelligible and useful to the fellowship in a context familiar to them, a context which had provided the institutional framework for most of Hooke's adult life. I argue that Waller's 'Life' was also intended to make the largest claims for Hooke's intellectual standing that the author dared in the context of the enmity between Hooke and Isaac Newton once the latter became president of the Royal Society. However, I also adduce fresh manuscript evidence that Waller actually compiled, but did not publish, a defence of Hooke's claim to have discovered the inverse square law of gravity, allowing us to glimpse a much more assertive biography of Hooke than the published version.

  6. Deficit or creativity: Cesare Lombroso, Robert Hertz, and the meanings of left-handedness.

    Science.gov (United States)

    Kushner, Howard I

    2013-01-01

    In the first decade of the twentieth century two influential researchers attempted to explain the origin and impact of left-handedness in human history. The first, the Turin physician Cesare Lombroso, often referred to as the father of modern criminology, was nearing the end of his long distinguished career. Lombroso tied left-handedness to criminality, insanity, and feeble mindedness. According to Lombroso, these groups shared biological regressions to primitive mentalities that could not be reversed by education or training. The second, French sociologist Robert Hertz, was at the beginning of a career cut short by his death in combat during the First World War. Hertz challenged Lombroso's claims, insisting that the predominance of right-handedness, whatever its biological substrate, was ultimately a cultural artefact driven by a primitive human urge to make sense of the world by dividing it into binary oppositions in which the right was viewed as sacred and the left as profane. Ending discrimination against left-handedness would, according to Hertz, unleash access to both hands and thus both hemispheres. The results, he insisted, would allow repressed talents and creativity to flourish. The conflicting views of Lombroso and Hertz have informed investigations of the causes and consequences of left-handedness until today. While the language of the debate has been reframed in current scientific discourses, left-handedness continues to be portrayed in the contradictory ways first elaborated by Lombroso and Hertz more than a century ago as either the cause of a variety of learning disabilities or as the key that can unlock creativity and talent. The debate also exposed the extent to which other cultural concerns, particularly anti-Semitism, informed theories of handedness.

  7. Unauthorised Biographies: An Analysis Under the Perspective of Robert Alexy's External Theory

    2015-12-01

    Full Text Available The present paperwork aimed to analyse whether or not the publication of a biography should require the prior authorisation from the subject  or their family. As there is, in this case, a collision between personality rights and freedom of speech, the proportionality test was used to solve such conflict. The first step was to define biography as a non-ficctional genre. The paperwork then aimed to define the theory of the principles, the external theory of the restriction of fundamental rights and the proportionality test developed by jurist Robert Alexy, which are largely used in Brazil by authors like Virgílio Afonso da Silva, Ingo Wolfgang Sarlet and Daniel Sarmento. It was observed that when fundamental rights collide, the proportionality must be verified and as a result there is a conditional precedence relation between the rights. In such case, the ceding right will be restricted by the preciding one. The external theory is a recognised manner of verifying whether the restriction of a fundamental right is legit or if it is a violation. The need for prior authorisation, based on the personality protection, restricts freedom of speech, on the other hand, its exemption is based on the right to freedom of speech. By applying the aforementioned method, a particular rule was developed and the conditions for it to be applicable: freedom of speech prevails over personality rights in given conditions (public figure, over suitable means, no expectation for privacy in the publication, diligence in the verification of truth or social and journalistic interest over the information

  8. Robert Burns and the Re-making of National Memory in Contemporary Scotland

    Directory of Open Access Journals (Sweden)

    2012-05-01

    Full Text Available Robert Burns, the eighteenth-century Scottish poet and song writer, continues to maintain a substantial cultural ‘afterlife’ in the twenty first century, both within Scotland and beyond. Achieving cult status in the nineteenth century, the power of Burns as a popular cultural icon remains undiminished. Where the appropriation of Burns as national icon in the nineteenth century was made manifest in statuary, commemorative objects, and painted portraits, the twenty-first century has been marked by the proliferation of the image of Burns in new forms and technologies, with Burns as product and brand logo, museum and heritage attraction, and tourism industry selling point. This recent flourishing of interest and engagement raises questions about why and how an eighteenth-century poet continues to be the object of such extensive cultural elaboration at this time. In approaching this question, some fruitful lines of enquiry are being suggested in recent discussions that have looked at the nineteenth-century Burns as a ‘mobilizing agent in collective memory production’ (Rigney 2011, 81. One such appraisal points to how the construction of Burns in the nineteenth century as an iconic figure of Scottish cultural memory has the potential to ‘be resignified as necessary in subsequent chronological and geographical sites’ (Davis 2010, 14. It is this potential for the resignification of Burns as a symbolic site for the nation’s memory that this paper explores. In pointing to Burns’ representation in a variety of popular forms and in public discourse, the paper examines how a writer comes to be invested and reinvested as the voice and persona of the nation.

    2010-12-01

    Full Text Available Este artigo procura investigar a leitura que o arquiteto Robert Venturi faz de alguns traços da obra de Le Corbusier, para conceber suas considerações sobre arquitetura e comunicação. Para isso, foram estudadas, de modo breve, as maneiras como Le Corbusier já fazia uso, em sua obra, de algumas categorias que, posteriormente, seriam atribuídas, excelentemente, aos ditos pós-modernos: a retórica, a alusão, a memória dos centro históricos e dos interiores decorados. Tendo em vista a obra geral do arquiteto suíço, é certo que essas categorias aparecem somente nas entrelinhas de seu projeto modernista de reorganização das cidades. Entretanto, uma leitura de minúcias revela alguns temas – especificamente o interesse de Corbusier nos monumentos de Paris, seus pórticos desenhados na Ville contemporaine (1921, e a lareira com motivos surrealistas na cobertura De Beistegui (1929 que seriam objeto de pleno interesse para historiadores e arquitetos da década de 1960. Justamente, nessa recuperação de traços obscuros de Corbusier, Venturi posiciona alguns de seus temas, especificamente em suas soluções residenciais, privilegiando – e, em alguns casos, mesmo exagerando, a imagem chaminé, duplicando sua altura ou colocando-a como grande ordenadora da planta. Todo esse debate será estudado tendo, como pano de fundo, escritos recentes que realizam um balanço crítico das rupturas engendradas pela dita arquitetura pós-moderna com os modernismos. Fazendo uso de considerações de Andreas Huyssen, Paul Virilio e Beatriz Colomina, entre outros, procurou-se ora delimitar, com maior clareza, a fronteira entre essas duas correntes do século 20, ora diluir seus contornos, revelando semelhanças que, eventualmente, fazem-nas indissociáveis.

  15. Distribution and origin of authigenic smectite clays in Cape Roberts Project Core 3, Victoria Land Basin, Antarctica

    Of some 800 m of lower Oligocene marine sediments cored continuously from the seafloor in the Victoria Land Basin of Antarctica at Cape Roberts Site CRP-3, the lower 500 m exhibit authigenic smectite clay coats on shallow-water sandstone grains. A scanning electron microscope/EDS study of 46 fracture sections confirms that the distribution of the clay coats through the unit is not uniform or evenly distributed, but rather varies with depth, original porosity, and the kinds and abundance of source materials. Our results suggest that smectite emplacement resulted from in-situ, low-temperature burial diagenesis rather than hydrothermal or fault-focused thermobaric fluids.

  16. LOS DERECHOS FUNDAMENTALES COMO NORMAS JURÍDICAS MATERIALES EN LA TEORÍA DE ROBERT ALEXY

    ABSTRACT. The theory of the civil rights of Robert Alexy is based on a material concept of rule of law. It is two-fold. On the one hand, is defined by the traits of the principles, consistent with the idea of ??correct argument. But on the other hand, weight is still the legal validity of the rules contained civil rights, constitutional rules considered. As argued in the work, this ambiguity of the norm theory allows for different approaches Alexy, positivist and positivist, which is a sign of its theoretical richness

    This volume is dedicated to Robert F. Tichy on the occasion of his 60th birthday. Presenting 22 research and survey papers written by leading experts in their respective fields, it focuses on areas that align with Tichy’s research interests and which he significantly shaped, including Diophantine problems, asymptotic counting, uniform distribution and discrepancy of sequences (in theory and application), dynamical systems, prime numbers, and actuarial mathematics. Offering valuable insights into recent developments in these areas, the book will be of interest to researchers and graduate students engaged in number theory and its applications.

    Full Text Available Cet article interroge le paysage urbain dans Le paradis des apparences (2004 de Robert Melançon en mobilisant tour à tour les concepts de « milieu » (Berque et d’« espaces mineur et majeur » (Desportes, qui invitent à une conception ouverte et dynamique du paysage. Soulignant tout d’abord l’intérêt du sujet melançonien pour les paysages « pauvres » de l’univers citadin, la réflexion se concentre ensuite sur l’importance de la médiation picturale et la valorisation toute baroque des apparences, des jeux d’illusions et autres trompe-l’œil dont fait son miel cette poésie par ailleurs pétrie d’une sobriété toute classique. This article questions the cityscape in Le paradis des apparences (2004 by Robert Melançon by discussing the concepts of « milieu » (Berque and « minor and major places » (Desportes that foster an open and dynamic conception of landscape. It first highlights the subject’s interest for “poor” and marginal cityscapes, before concentrating on the importance of the pictorial mediation and the baroque valorization of appearances, illusions, and other deceptive trompe-l’oeil, which are the very matter of this poetry that may not be as classical and understated as it first appears.

    Full Text Available RESUMEN. La teoría de los derechos fundamentales de Robert Alexy se fundamenta en un concepto material de norma jurídica que es de carácter doble. Por un lado, se define por los rasgos propios de los principios, en consonancia con la idea de argumentación correcta. Pero, por otro lado, sigue teniendo peso la validez jurídica de las normas que contienen derechos fundamentales, consideradas como reglas constitucionales. Tal y como se argumenta en el trabajo, esta ambigüedad de la teoría de la norma de Alexy permite distintos acercamientos, positivistas y no positivistas, que es signo de su riqueza teórica. ABSTRACT.

  20. The Sciences: An Integrated Approach, 2nd Edition (by James Trefil and Robert M. Hazen)

    "You're going to teach the organic chemistry section of the Natural Science class?" - one of my biology colleagues asked me last semester - "Better you than me!" "You are?" added a chemistry professor, with interest. Yet these same people ardently believe that all our students should have a basic understanding of carbon's remarkable bonding capabilities and how they relate to life on Earth. If our art or economics majors can learn about organic chemistry and genetics and astronomy, our faculty should be able to teach those same topics, regardless of their acknowledged specialties. The basis of a scientifically literate society is not expertise in specific arcane subfields of science. Scientific literacy is a general understanding of what science is, what science can and cannot do, and what scientific accomplishments have occurred over the centuries. If you subscribe to this definition of scientific literacy, James Trefil and Robert M. Hazen's The Sciences: An Integrated Approach can help you and your general science students. The self-avowed purpose of this text is to address science illiteracy in America. Trefil and Hazen propose that the best way to combat scientific illiteracy is to provide integrated science courses that focus on a broad understanding of science, rather than the specialized knowledge available to a science major. The new edition of The Sciences has been influenced by the 1996 publication of the National Research Council's National Science Education Standards. While the first edition of Trefil and Hazen's book admirably addressed the integration of the natural and physical sciences, in this second edition, the authors have increased the connections between science and real-world situations and have made a more conscious effort to emphasize the process of science and the overlapping nature of scientific disciplines. The text is based on 25 "scientific concepts", one per chapter. These concepts are clearly explained in relatively jargon
