Return of the living dead: Re-reading Pierre Flourens' contributions to neurophysiology and literature.

Historians of neurophysiology remember Marie Jean Pierre Flourens (1794-1867) for his experimental approach to nineteenth-century debates on cortical localization and, in particular, for his successful attacks on Frantz Joseph Gall's (1758-1828) phrenology (Gall and Spurzheim, 1810-19). Whereas Gall and his colleague, Johann Gaspar Spurzheim (1776-1832), posited correlations between features of the skull and brain development and claimed to have localized character traits, competencies and temperaments in specific cortical regions, Flourens advocated cerebral equipotentiality and provided empirical as well as philosophical grounds for his theories. Flourens has also been recognized for his contributions to the understanding of the cerebellum's role in the coordination of movement, the localization of a respiratory center in the medulla oblongata, the relationship between the semicircular canals and balance, the role of the periosteum in bone growth and regeneration, and finally, the anesthetic properties of chloroform. Less known to historians of neuroscience is the fact that Pierre Flourens was not only a neurophysiologist and Secrétaire Perpetuel of the French Académie des Sciences, he was also a member of the Académie Française, France's most prestigious literary academy. Examining Flourens' contributions as a writer and, at the same time, a prime target for criticism and caricature from journalists, yields a particularly interesting example of the problematic relations between different genres of science writing and their respective publics in mid-nineteenth-century France. © 2013 Elsevier B.V.

Plant anesthesia supports similarities between animals and plants: Claude Bernard's forgotten studies.

The French scientist Claude Bernard (1813-1878) is famous for his discoveries in physiology and for introducing rigorous experimental methods to medicine and biology. One of his major technical innovations was the use of chemicals in order to disrupt normal physiological function to test hypotheses. But less known is his conviction that the physiological functions of all living organisms rely on the same underlying principles. He hypothesized that similarly to animals, plants are also able to sense changes in their environment. He called this ability "sensitivity." In order to test his ideas, he performed anesthesia on plants and the results of these experiments were presented in 1878 in "Leçonssur les phénomènes de la vie communs aux animaux et aux végétaux." The phenomena described by Claude Bernard more than a century ago are not fully understood yet. Here, we present a short overview of anesthetic effects in animals and we discuss how anesthesia affects plant movements, seed germination, and photosynthesis. Surprisingly, these phenomena may have ecological relevance, since stressed plants generate anesthetics such as ethylene and ether. Finally, we discuss Claude Bernard's interpretations and conclusions in the perspective of modern plant sciences.

Jean-Baptiste Labat and the buccaneer barbecue in seventeenth-century Martinique.

PubMed

Toczyski, Suzanne

2010-01-01

If, as the sociologist Pierre L. van den Berghe has suggested, cuisine is a significant expression of man's sociability, one might say that the seventeenth-century missionary Jean-Baptiste Labat was the single most social animal in the Caribbean islands in the 1690s. Although his primary responsibility on the island of Martinique was to serve the island's multiethnic population as a spiritual leader, le père Labat's memoirs chronicle the diverse culinary experiences of the missionary as he literally eats his way around the island, learning to prepare such delicacies as cocoa confit, roasted manatee, lizard en brochette, and parakeet en daube. Positing his unbridled interest in the culinary arts as a mark of his “obedience” to the duties assigned him as missionary, Labat's taxonomy of island delicacies and exotic tastes no doubt titillated the curiosity of his mainland readers while nevertheless grounding itself strongly in the values of order, authenticity, and industry so essential to Labat's apostolic mission. This article focuses on two “buccaneer barbecues” as examples of gastronomical experiences through which Labat was able to construct and negotiate new social, cultural, and symbolic meanings, exploring identity politics through the frame of the culinary arts in seventeenth-century Martinique.

The microbiologist Jean Comandon is famous for his studies on the movement of the syphilis bacteria as differentiated in various forms by ultramicroscope. He was also a pioneer on the technical application of the microcinematography in laboratory research. His collaboration with clinicians and surgeons in the study of various pathological disorders is little known. From 1918 to the 1920s, he collaborated with such neurologists as André Thomas, Jean Athanase Sicard, and others in the study of various neurological disorders by using cinematography as a scientific tool for understanding the clinical and pathological mechanisms of diseases. These collaborations allowed him to be involved in the beginnings of the French cinematography industry, especially with Charles Pathé who established a small film studio laboratory in Vincennes where a multidisciplinary group improved the application of cinematography in clinical medical practice.

Monocarboxylate transporters (MCTs) constitute a family of 14 members among which MCT1-4 facilitate the passive transport of monocarboxylates such as lactate, pyruvate and ketone bodies together with protons across cell membranes. Their anchorage and activity at the plasma membrane requires interaction with chaperon protein such as basigin/CD147 and embigin/gp70. MCT1-4 are expressed in different tissues where they play important roles in physiological and pathological processes. This review focuses on the brain and on cancer. In the brain, MCTs control the delivery of lactate, produced by astrocytes, to neurons, where it is used as an oxidative fuel. Consequently, MCT dysfunctions are associated with pathologies of the central nervous system encompassing neurodegeneration and cognitive defects, epilepsy and metabolic disorders. In tumors, MCTs control the exchange of lactate and other monocarboxylates between glycolytic and oxidative cancer cells, between stromal and cancer cells and between glycolytic cells and endothelial cells. Lactate is not only a metabolic waste for glycolytic cells and a metabolic fuel for oxidative cells, but it also behaves as a signaling agent that promotes angiogenesis and as an immunosuppressive metabolite. Because MCTs gate the activities of lactate, drugs targeting these transporters have been developed that could constitute new anticancer treatments.

Variability, constraints, and creativity. Shedding light on Claude Monet.

PubMed

Stokes, P D

2001-04-01

Recent experimental research suggests 2 things. The first is that along with learning how to do something, people also learn how variably or differently to continue doing it. The second is that high variability is maintained by constraining, precluding a currently successful, often repetitive solution to a problem. In this view, Claude Monet's habitually high level of variability in painting was acquired during his childhood and early apprenticeship and was maintained throughout his adult career by a continuous series of task constraints imposed by the artist on his own work. For Monet, variability was rewarded and rewarding.

Jeans instability in a universe with dissipation

Kremer, Gilberto M.; Richarte, Martín G.; Teston, Felipe

2018-01-01

The problem of Jeans gravitational instability is investigated for static and expanding universes within the context of the five and thirteen field theories which account for viscous and thermal effects. For the five-field theory a general dispersion relation has been derived with the help of relevant linearized perturbation equations, showing that the shear viscosity parameter alters the propagating modes for large and small wavelengths. The behavior of density and temperature contrasts are analyzed for the hard-sphere model in detail. In the small wavelengths regime, increasing the amount of shear viscosity into the system forces the harmonic perturbations to damp faster, however, in the opposite limit larger values of shear viscosity lead to smaller values of density and temperature contrasts. We also consider the hyperbolic case associated with the thirteen-field theory which involves two related parameters, namely the shear viscosity and the collision frequency, the last one is due to the production terms which appear in the Grad method. The dispersion relation becomes a polynomial in the frequency with two orders higher in relation to the five-field theory, indicating that the effects associated with the shear viscosity and heat flux are nontrivial. The profile of Jeans mass in terms of the temperature and number density is explored by contrasting with several data of molecular clouds. Regarding the dynamical evolution of the density, temperature, stress and heat flux contrasts for a universe dominated by pressureless matter, we obtain also damped harmonic waves for small wavelengths. In the case of large wavelengths, the density and temperature contrasts grow with time (due to the Jeans mechanism) while the stress and heat flux contrasts heavily decay with time. For an expanding universe, the Jeans mass and Jeans length are obtained and their physical consequences are explored.

Jeans instability is examined in detail in uniform dusty magnetoplasmas taking care of collisional and non-zero finite thermal effects in addition to the quantum characteristics arising through the Bohm potential and the Fermi degenerate pressure using the quantum hydrodynamic model of plasmas. It is found that the presence of the dust-lower-hybrid wave, collisional effects of plasma species, thermal effects of electrons, and the quantum mechanical effects of electrons have significance over the Jeans instability. Here, we have pointed out a new class of dissipative instability in quantum plasma regime.

Jean Francheteau, pioneering marine geologist and geophysicist, AGU Fellow, and emeritus professor at the University of Brest (Université de Bretagne Occidentale), died on 21 July in St-Renan, Brittany, France, at the age of 67 after a long illness. With his passing, the field of Earth sciences lost a major contributor to the development of a definitive theory of plate tectonics and one of the first to make visual geological observations on the deep seafloor. Such scientific accomplishments, coupled with his personal charm and the ability to collaborate with researchers from many institutions, ensured that he had a huge influence not only on the world of research but also on teaching and the application of ethics to science. Jean arrived at Scripps Institution of Oceanography in La Jolla, Calif., in 1966 after obtaining a diploma in mining engineering at the prestigious Éole Nationale Supérieure de la Métallurgie et de l'Industrie des Mines in Nancy, France. He chose Victor Vacquier as his thesis supervisor and began working in Vic's lab with John Sclater, ostensibly on heat flow measurements.

Demonic possession by Jean Lhermitte.

PubMed

Drouin, E; Péréon, T; Péréon, Y

2017-08-01

The name of the French neurologist and psychiatrist Jean Lhermitte (1877-1959) is most often associated with the sign he described back in 1927 in three patients with multiple sclerosis. We are reporting unpublished handwritten notes by Jean Lhermitte about 'demonic possession', which date from the 1950s. Drawing from his experiences in neuropsychiatry, Lhermitte gathered notable case reviews as well as individual case histories. For him, cases of demonic possession are of a psychiatric nature with social background exerting a strong influence. Like Freud did earlier, Lhermitte believes that the majority of those possessed people have been subjected to sexual trauma with scruples, often linked to religion. Demonic possession cases were not so rare in the 1950s but their number has nowadays declined substantially with the development of modern psychiatry. Copyright © 2017 L'Encéphale, Paris.

Pierre Robin sequence results from a cascade of events that occur during embryologic development and frequently presents with cleft palate. Some studies have shown speech outcomes to be worse in patients with Pierre Robin sequence after cleft palate repair. A cohort of Pierre Robin sequence patients who all required an airway intervention and nasogastric feeding in the neonatal period were identified and speech outcomes assessed at 5 years of age. A cleft- and sex-matched non-Pierre Robin sequence, cleft palate-only comparison group was also identified from the same institution and study period. A total of 24 patients with Pierre Robin sequence that required airway and nutritional support in the neonatal period were matched for age, sex, and cleft type to a group of 24 non-Pierre Robin sequence cleft patients. There was no significant difference in the incidence of oronasal fistula between the groups. Secondary surgery for velopharyngeal incompetence was significantly more (p = 0.017) in the Pierre Robin sequence group, who also had significantly greater nasality (p = 0.031) and cleft speech characteristic (p = 0.023) scores. The authors hypothesize that other factors may exist in Pierre Robin sequence that may lead to poor speech outcomes. The authors would suggest counseling parents of children with Pierre Robin sequence that have required a neonatal airway intervention, that speech development may be poorer than in other children with cleft palate, and that these children will have a significantly higher incidence of secondary speech surgery.

An algorithm developed to calculate the performance of Claude-Cycle ocean thermal energy conversion (OTEC) systems is described. The algorithm treats each component of the system separately and then interfaces them to form a complete system, allowing a component to be changed without changing the rest of the algorithm. Two components that are subject to change are the evaporator and condenser. For this study we developed mathematical models of a channel-flow evaporator and both a horizontal jet and spray director contact condenser. The algorithm was then programmed to run on SERI's CDC 7600 computer and used to calculate the effect onmore » performance of deaerating the warm and cold water streams before entering the evaporator and condenser, respectively. This study indicates that there is no advantage to removing air from these streams compared with removing the air from the condenser.« less

Faults and structure in the Pierre Shale, central south Dakota

Nichols, Thomas C.; Collins, Donley S.; Jones-Cecil, Meridee; Swolfs, Henri S.

1994-01-01

Numerous faults observed at the surface and (or) determined by geometric and geophysical methods to be present as much as several hundred meters below the surface (near-surface faults) have been mapped in a 2,000-km2 area west of Pierre, S. Dakota. Many of these faults surround an east-west-trending structural high that has been mapped on the lower part of the Virgin Creek Member of the Pierre Shale. Generally, the geometry and displacement of many of the faults precludes slumping from surficial erosion as a mechanism to explain the faults. Seismic-reflection data indicate that several of the faults directly overlie faults in Precambrian basement that have cumulative vertical displacements of as much as 340 m. The structural high is interpreted to have been uplifted by displacements along faults that cut Upper Cretaceous sedimentary rocks. Recent low-level seismicity and fluvial-geomorphic studies of stream patterns, gradients, and orders suggest that rejuvenation of drainages may be taking place as a result of rebound or other tectonic activity. The studies indicate that repeated uplift and subsidence may have been the cause of extensive faulting mapped in the Pierre Shale since its deposition in Cretaceous time. Surficial fault displacements that cause damage to engineered structures are thought to be the result of construction-induced rebound in the Pierre Shale, although tectonic uplift cannot be ruled out as a cause.

THERMALLY DRIVEN ATMOSPHERIC ESCAPE: TRANSITION FROM HYDRODYNAMIC TO JEANS ESCAPE

DOE Office of Scientific and Technical Information (OSTI.GOV)

Volkov, Alexey N.; Johnson, Robert E.; Tucker, Orenthal J.

2011-03-10

Thermally driven escape from planetary atmospheres changes in nature from an organized outflow (hydrodynamic escape) to escape on a molecule-by-molecule basis (Jeans escape) with increasing Jeans parameter, {lambda}, the ratio of the gravitational to thermal energy of the atmospheric molecules. This change is described here for the first time using the direct simulation Monte Carlo method. When heating is predominantly below the lower boundary of the simulation region, R{sub 0}, and well below the exobase of a single-component atmosphere, the nature of the escape process changes over a surprisingly narrow range of Jeans parameters, {lambda}{sub 0}, evaluated at R{sub 0}.more » For an atomic gas, the transition occurs over {lambda}{sub 0} {approx} 2-3, where the lower bound, {lambda}{sub 0} {approx} 2.1, corresponds to the upper limit for isentropic, supersonic outflow. For {lambda}{sub 0} > 3 escape occurs on a molecule-by-molecule basis and we show that, contrary to earlier suggestions, for {lambda}{sub 0} > {approx}6 the escape rate does not deviate significantly from the familiar Jeans rate. In a gas composed of diatomic molecules, the transition shifts to {lambda}{sub 0} {approx} 2.4-3.6 and at {lambda}{sub 0} > {approx}4 the escape rate increases a few tens of percent over that for the monatomic gas. Scaling by the Jeans parameter and the Knudsen number, these results can be applied to thermally induced escape of the major species from solar and extrasolar planets.« less

Prajapat, V.; Sutar, D. L.; Pensia, R. K.

2018-05-01

This paper treats the Jeans instability improved at the theoretical investigation of the presence of viscosity and resistivity in the porous medium. Following the normal mode analysis using the QMHD model, the dispersion relation is discussed for wave propagation in longitudinal and transverse direction. The Jeans criteria of instability are affected by the presence of porosity. The graphical presentation shows that porosity has a stabilizing effect while resistivity has destabilizing effect in the system.

Composite turbine blade design options for Claude (open) cycle OTEC power systems

DOE Office of Scientific and Technical Information (OSTI.GOV)

Penney, T R

1985-11-01

Small-scale turbine rotors made from composites offer several technical advantages for a Claude (open) cycle ocean thermal energy conversion (OTEC) power system. Westinghouse Electric Corporation has designed a composite turbine rotor/disk using state-of-the-art analysis methods for large-scale (100-MW/sub e/) open cycle OTEC applications. Near-term demonstrations using conventional low-pressure turbine blade shapes with composite material would achieve feasibility and modern credibility of the open cycle OTEC power system. Application of composite blades for low-pressure turbo-machinery potentially improves the reliability of conventional metal blades affected by stress corrosion.

With the mission specialist's assistance, Endeavour's crew captured the Hubble Space Telescope (HST) on December 4, 1993. Four of the seven crew members will work in alternating pairs outside Endeavour's shirt sleeve environment to service the giant telescope. Electronic still photography is a relatively new technology which provides the means for a handheld camera to electronically capture and digitize an image with resolution approaching film quality. The electronic still camera has flown as an experiment on several other shuttle missions.

The aesthetics of laboratory inscription: Claude Bernard's Cahier Rouge.

PubMed

Sattar, Atia

2013-03-01

This essay explores the aesthetic sensibilities of the French physiologist Claude Bernard (1813-1878). In particular, it analyzes the Cahier Rouge (1850-1860), Bernard's acclaimed laboratory notebook. In this notebook, Bernard articulates the range of his experience as an experimental physiologist, juxtaposing without differentiation details of laboratory procedure and more personal queries, doubts, and reflections on experimentation, life, and art. Bernard's insights, it is argued, offer an aesthetic and phenomenological template for considering experimentation. His physiological point of view ranges from his own bodily aesthesis or sensory perception, through personal reflections on scientific discovery as an artistic process, to a broader metaphysical conception of life as an artistic creation. Such an aesthetic approach to physiology enables Bernard to reconcile his empirical methodology and his romantic idealism; it offers the history of laboratory science a framework for considering the individual, bodily, and emotional labor inherent in physiological experimentation.

Jeans instability with exchange effects in quantum dusty magnetoplasmas

DOE Office of Scientific and Technical Information (OSTI.GOV)

Jamil, M., E-mail: jamil.gcu@gmail.com; Rasheed, A.; Rozina, Ch.

2015-08-15

Jeans instability is examined in magnetized quantum dusty plasmas using the quantum hydrodynamic model. The quantum effects are considered via exchange-correlation potential, recoil effect, and Fermi degenerate pressure, in addition to thermal effects of plasma species. It is found that the electron exchange and correlation potential have significant effects over the threshold value of wave vector and Jeans instability. The presence of electron exchange and correlation effect shortens the time of dust sound that comparatively stabilizes the self gravitational collapse. The results at quantum scale are helpful in understanding the collapse of the self-gravitating dusty plasma systems.

The influence of dust-neutral collisions, polarization force, and electron radiative condensation is analysed on the Jeans (gravitational) instability of partially ionized strongly coupled dusty plasma (SCDP) using linear perturbation (normal mode) analysis. The Boltzmann distributed ions, dynamics of inertialess electrons, charged dust and neutral particles are considered. Using the plane wave solutions, a general dispersion relation is derived which is modified due to the presence of dust-neutral collisions, strong coupling effect, polarization force, electron radiative condensation, and Jeans dust/neutral frequencies. In the long wavelength perturbations, the Jeans instability criterion depends upon strong coupling effect, polarization interaction parameter, and thermal loss,more » but it is independent of dust-neutral collision frequency. The stability of the considered configuration is analysed using the Routh–Hurwitz criterion. The growth rates of Jeans instability are illustrated, and stabilizing influence of viscoelasticity and dust-neutral collision frequency while destabilizing effect of electron radiative condensation, polarization force, and Jeans dust-neutral frequency ratio is observed. This work is applied to understand the gravitational collapse of SCDP with dust-neutral collisions.« less

The effect of spin induced magnetization and electrical resistivity incorporating the viscosity of the medium is examined on the Jeans instability of quantum magnetoplasma. Formulation of the system is done by using the quantum magnetohydrodynamic model. The analysis of the problem is carried out by normal mode analysis theory. The general dispersion relation is derived from set of perturbed equations to analyse the growth rate and condition of self-gravitational Jeans instability. To discuss the influence of resistivity, magnetization, and viscosity parameters on Jeans instability, the general dispersion relation is reduced for both transverse and longitudinal mode of propagations. In themore » case of transverse propagation, the gravitating mode is found to be affected by the viscosity, magnetization, resistivity, and magnetic field strength whereas Jeans criterion of instability is modified by the magnetization and quantum parameter. In the longitudinal mode of propagation, the gravitating mode is found to be modified due to the viscosity and quantum correction in which the Jeans condition of instability is influenced only by quantum parameter. The other non-gravitating Alfven mode in this direction is affected by finite electrical resistivity, spin induced magnetization, and viscosity. The numerical study for the growth rate of Jeans instability is carried out for both in the transverse and longitudinal direction of propagation to the magnetic field. The effect of various parameters on the growth rate of Jeans instability in quantum plasma is analysed.« less

The effect of radiative heat-loss function and rotation on the Jeans instability of quantum plasma is investigated. The basic set of equations for this problem is constructed by considering quantum magnetohydrodynamic (QMHD) model. Using normal mode analysis, the general dispersion relation is obtained. This dispersion relation is studied in both, longitudinal and transverse direction of propagations. In both case of longitudinal and transverse direction of propagation, the Jeans instability criterion is modified due to presence of radiative heat-loss function and quantum correction.

Kinetic theory of Jeans instability of a dusty plasma.

Pandey, B P; Lakhina, G S; Krishan, V

1999-12-01

A kinetic theory of the Jeans instability of a dusty plasma has been developed in the present work. The effect of grain charge fluctuations due to the attachment of electrons and ions to the grain surface has been considered in the framework of Krook's collisional model. We demonstrate that the grain charge fluctuations alter the growth rate of the gravitational collapse of the dusty plasma. The Jeans length has been derived under limiting cases, and its dependence on the attachment frequency is shown. In the absence of gravity, we see that the damping rate of the dust acoustic mode is proportional to the electron-dust collision frequency.

Schmidgen, Henning

2013-01-01

This paper explores the relation between biological and historical time with respect to Claude Bernard's Lectures on the Phenomena of Life Common to Animals and Plants (1878). These lectures mirror Bernard's turn from the experimental physiology of animal organisms to a "general physiology" of elementary organisms, or cells, and discuss the problematic interrelation of science, life, and time. The paper argues that experimental life sciences in Bernard's sense are always also "living sciences," i.e., sciences in dynamic development. The perspectives of this conception are discussed with reference to Hans-Jörg Rheinberger's historical studies concerning the materiality and semiotics of "experimental systems."

The Jeans self-gravitational instability is studied for quantum plasma composed of weakly coupled degenerate electron fluid and non-degenerate strongly coupled ion fluid. The formulation for such system is done on the basis of two fluid theory. The dynamics of weakly coupled degenerate electron fluid is governed by inertialess momentum equation. The quantum forces associated with the quantum diffraction effects and the quantum statistical effects act on the degenerate electron fluid. The strong correlation effects of ion are embedded in generalized viscoelastic momentum equation including the viscoelasticity and shear viscosities of ion fluid. The general dispersion relation is obtained using themore » normal mode analysis technique for the two regimes of propagation, i.e., hydrodynamic and kinetic regimes. The Jeans condition of self-gravitational instability is also obtained for both regimes, in the hydrodynamic regime it is observed to be affected by the ion plasma oscillations and quantum parameter while in the kinetic regime in addition to ion plasma oscillations and quantum parameter, it is also affected by the ion velocity which is modified by the viscosity generated compressional effects. The Jeans critical wave number and corresponding critical mass are also obtained for strongly coupled quantum plasma for both regimes.« less

The effect of suspended particles on Jean's criterion for gravitational instability

NASA Technical Reports Server (NTRS)

Wollkind, David J.; Yates, Kemble R.

1990-01-01

The effect that the proper inclusion of suspended particles has on Jeans' criterion for the self-gravitational instability of an unbounded nonrotating adiabatic gas cloud is examined by formulating the appropriate model system, introducing particular physically plausible equations of state and constitutive relations, performing a linear stability analysis of a uniformly expanding exact solution to these governing equations, and exploiting the fact that there exists a natural small material parameter for this problem given by N sub 1/n sub 1, the ratio of the initial number density for the particles to that for the gas. The main result of this investigation is the derivation of an altered criterion which can substantially reduce Jeans' original critical wavelength for instability. It is then shown that the existing discrepancy between Jeans' theoretical prediction using and actual observational data relevant to the Andromeda nebula M31 can be accounted for by this new criterion of assuming suspended particles of a reasonable grain size and distribution to be present.

PubMed

Meier, Monika

2007-01-01

The German writerJean Paul (Johann Paul Friedrich Richter, 1763-1825) and his friendJohann Bernhard Hermann (1761-1790) became acquainted with the thoughts of late Enlightenment at the University of Leipzig. They particularly appreciated the anthropology of Ernst Platner, who taught philosophy and aesthetics as well as medicine. Their confidential correspondence contains reflections on their respective situation and well being. Both write about feeling ill and label their illness "hypochondria". In the course of the correspondence Jean Paul's understanding of hypochondria evolves from an illness of the entrails as he follows Hermann, who supports the modern concept of hypochondria as an illness of the nerves. Two important themes from this correspondence recur in Jean Paul's novels and tales: firstly, his way of expressing comfort is related to his aesthetics, and secondly, the satirical way of portraying at least certain aspects of illness as imaginary reappears in his first successful novel "The Invisible Lodge" (1793).

We describe a new method of identifying night-time clouds over the Pierre Auger Observatory using infrared data from the Imager instruments on the GOES-12 and GOES-13 satellites. We compare cloud identifications resulting from our method to those obtained by the Central Laser Facility of the Auger Observatory. Using our new method we can now develop cloud probability maps for the 3000 km2 of the Pierre Auger Observatory twice per hour with a spatial resolution of ˜2.4 km by ˜5.5 km. Our method could also be applied to monitor cloud cover for other ground-based observatories and for space-based observatories.

Dumont, Quentin; Cole, Richard B

The development of electrospray ionization mass spectrometry (ESI-MS) was a 20th century occurrence that underwent rapid acceleration especially in the 1990's. However, long prior to its coupling with mass spectrometry, the electrification of liquids had been studied in a variety of contexts. Although initial reports describing cone formation upon electrification of water drops came out of England, the first true experiments investigating the electrospray phenomenon were performed in the middle of the 18th century by Abbé Jean-Antoine Nollet. The current report, associated with the French Regional Issue of Mass Spectrometry Reviews, examines the contributions of Abbé Nollet to the earliest understanding of the electrospray phenomenon. A description of his accomplishments is placed in the context of the societal and scientific developments of the "Age of Enlightenment" out of which Jean-Antoine Nollet arose. © 2013 Wiley Periodicals, Inc.

Jeans instability in a viscoelastic fluid

The well known Jeans instability is studied for a viscoelastic gravitational fluid using generalized hydrodynamic equations of motions. It is found that the threshold for the onset of instability appears at higher wavelengths in a viscoelastic medium. Elastic effects playing a role similar to thermal pressure are found to lower the growth rate of the gravitational instability. Such features may manifest themselves in matter constituting dense astrophysical objects.

Pierre Robin sequence (formerly a syndrome) is named after the French stomatologist who, in 1923 and 1934, described the problems associated with micrognathia in newborn. It comprises mandibular micrognathia, U-shaped cleft palate, and glossoptosis. The typical symptoms are hypoxaemia, noisy breathing, snoring, stridor, cyanosis, bradycardia, feeding difficulties, and failure to thrive. Distraction osteogenesis has recently been considered as a surgical option for early intervention to lengthen the mandible and relieve respiratory problems. Piezosurgery offers a modality to make precise bone cuts preserving vital structures, minimizing the invasiveness of the surgical procedure, and offering bloodless field. We present case of 1-year-old male malnourished child with Pierre Robin sequence and tracheostomy in situ since day 11 of his birth. The staged treatment plan involving mandibular lengthening in which mandibular osteotomies were performed with the piezoelectric scalpel followed by decannulation of tracheostomy, which has been described in detail in this article.

Ultrahigh Energy Neutrinos at the Pierre Auger Observatory

DOE PAGES

Abreu, P.; Aglietta, M.; Ahlers, M.; ...

2013-01-01

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

Because the insight is raising that waste prevention needs an integral product chain approach, a product chain project was awarded with an International Solid Waste Association grant. The project decided to focus on jeans because of the large environmental impacts of cotton and the low recycling rates. The project used an open innovative approach by involving many actors from the different phases of the chain and included student and applied researchers. In a 'design jeans for recycling' students' workshop, prototypes of jeans that are easier to recycle have been developed. Integrating the new generation from different disciplines in the project proved to be very successful. The results show that an open innovation process can lead to very creative ideas and that lessons learned from this project could be used to develop new chain projects for other products. An important condition is that key actors are willing to cooperate in an open innovation approach. © The Author(s) 2014.

How Pierre Janet used pathological psychology to save the philosophical self.

PubMed

Carroy, J; Plas, R

2000-01-01

According to traditional French historiography, French scientific psychology was born when it differentiated itself from philosophy. This split between the two disciplines is attributed to Taine and Ribot, who, consequently, are considered to be the "founding fathers" of French psychology. In this paper we shall examine the case of Pierre Janet, who, at the turn of the century, was recognized worldwide as the most important French psychologist. It is generally said that he was the follower of Ribot and of Charcot. However, he was also Paul Janet's nephew. Paul Janet was a very well known and influential philosopher of the so-called French "spiritualistic" school, for which psychology was central to philosophy. In 1889, Pierre Janet published his doctoral dissertation, L'Automatisme psychologique, which was immediately considered to be a classic in psychology. We shall argue that this book is as much indebted to the old spiritualistic psychology, which claimed the substantial unity of the self, as to the new psychology at the time, which questioned it. With Pierre Janet, the split between psychology and philosophy in France was reconsidered. It would be more accurate to speak in terms of a compromise between philosophy and the "new" physiological and pathological psychology. Copyright 2000 John Wiley & Sons, Inc.

Claude Bernard presented most of his fundamental results to the Société de Biologie, including proof of the modulation of the nervous system by the internal micromilieu. However, he did not describe the principle of a stable internal milieu as a condition for free life. Physiology, which is a part of biology, was not founded on cellular biology. Rather, Claude Bernard considered chemistry, anatomy and histology as the necessary auxiliary sciences for physiology. His articles are direct pictures, and not isolated ones, despite possible limitations, from a pre-montage movie of the physiological revolution he thought he had initiated, but not finished.

AugerPrime: the upgrade of the Pierre Auger Observatory

Sarazin, Frederic; Pierre Auger Collaboration Collaboration

2017-01-01

The nature and origin of ultra-high energy cosmic-rays (UHECRs) remain largely a mystery despite a wealth of new information obtained in recent years at the Pierre Auger Observatory and elsewhere. Mass composition studies performed at Auger appear to challenge the historical view that the UHECR primaries (at least for energies greater than 1019 eV) are all protons, and the observation of a GZK-like flux suppression in the cosmic-ray spectrum is counterbalanced by the absence of point source observations and the relatively weak anisotropy of the UHECR sky. In order to resolve this apparent contradiction, the Pierre Auger collaboration is embarking in an upgrade of the Observatory (``AugerPrime'') with the goal of extending the mass composition measurements beyond the observed flux suppression. In this presentation, the science case for the upgrade and its technical realization will be described and discussed especially with regards to the existence of GZK photons and neutrinos.

Simulation and statistical analysis for the optimization of nitrogen liquefaction plant with cryogenic Claude cycle using process modeling tool: ASPEN HYSYS

2017-09-01

Cryogenic technology is used for liquefaction of many gases and it has several applications in food process engineering. Temperatures below 123 K are considered to be in the field of cryogenics. Extreme low temperatures are a basic need for many industrial processes and have several applications, such as superconductivity of magnets, space, medicine and gas industries. Several methods can be used to obtain the low temperatures required for liquefaction of gases. The process of cooling or refrigerating a gas to a temperature below its critical temperature so that liquid can be formed at some suitable pressure, which is below the critical pressure, is the basic liquefaction process. Different cryogenic cycle configurations are designed for getting the liquefied form of gases at different temperatures. Each of the cryogenic cycles like Linde cycle, Claude cycle, Kapitza cycle or modified Claude cycle has its own advantages and disadvantages. The placement of heat exchangers, Joule-Thompson valve and turboexpander decides the configuration of a cryogenic cycle. Each configuration has its own efficiency according to the application. Here, a nitrogen liquefaction plant is used for the analysis purpose. The process modeling tool ASPEN HYSYS can provide a software simulation approach before the actual implementation of the plant in the field. This paper presents the simulation and statistical analysis of the Claude cycle with the process modeling tool ASPEN HYSYS. It covers the technique used to optimize the liquefaction of the plant. The simulation results so obtained can be used as a reference for the design and optimization of the nitrogen liquefaction plant. Efficient liquefaction will give the best performance and productivity to the plant.

Atmospheric monitoring and model applications at the Pierre Auger Observatory

The Pierre Auger Observatory detects high-energy cosmic rays with energies above ˜1017 eV. It is built as a multi-hybrid detector measuring extensive air showers with different techniques. For the reconstruction of extensive air showers, the atmospheric conditions at the site of the Observatory have to be known quite well. This is particularly true for reconstructions based on data obtained by the fluorescence technique. For these data, not only the weather conditions near ground are relevant, most important are altitude-dependent atmospheric profiles. The Pierre Auger Observatory has set up a dedicated atmospheric monitoring programme at the site in the Mendoza province, Argentina. Beyond this, exploratory studies were performed in Colorado, USA, for possible installations in the northern hemisphere. In recent years, the atmospheric monitoring programme at the Pierre Auger Observatory was supplemented by applying data from atmospheric models. Both GDAS and HYSPLIT are developments by the US weather department NOAA and the data are freely available. GDAS is a global model of the atmospheric state parameters on a 1 degree geographical grid, based on real-time measurements and numeric weather predictions, providing a full altitude-dependent data set every 3 hours. HYSPLIT is a powerful tool to track the movement of air masses at various heights, and with it the aerosols. Combining local measurements of the atmospheric state variables and aerosol scattering with the given model data, advanced studies about atmospheric conditions can be performed and high precision air shower reconstructions are achieved.

2016-01-01

This thematic issue of Comptes rendus Geoscience has been assembled to honor the memory of our late colleague and friend Jean-François Stéphan. Jean-François was a great scientist, specialized in tectonics, and a great colleague who devoted his time for his community. His work and actions deeply imprinted both the French and the International Earth Science communities. This volume brings together contributions of colleagues of Jean-François, who were also close friends or colleagues who knew and deeply appreciated him. Naturally, tectonics is the common theme of these contributions. Some of the papers presented here focus on tectonic questions and/or regions Jean-François worked on during his career; other papers present studies Jean-François motivated or encouraged in one way or another; other papers are simply tectonic studies he would have liked. Taken together, the nine papers of this thematic issue take the reader on a beautiful trip, from past to current tectonics.

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

Measurement of the Muon Production Depths at the Pierre Auger Observatory

DOE PAGES

Collica, Laura

2016-09-08

The muon content of extensive air showers is an observable sensitive to the primary composition and to the hadronic interaction properties. The Pierre Auger Observatory uses water-Cherenkov detectors to measure particle densities at the ground and therefore is sensitive to the muon content of air showers. We present here a method which allows us to estimate the muon production depths by exploiting the measurement of the muon arrival times at the ground recorded with the Surface Detector of the Pierre Auger Observatory. The analysis is performed in a large range of zenith angles, thanks to the capability of estimating and subtracting the electromagnetic component, and for energies betweenmore » $$10^{19.2}$$ and $$10^{20}$$ eV.« less

J. Jeans' idealism about space and its influences on E.A. Milne at the dawn of modern cosmology

NASA Astrophysics Data System (ADS)

Macchia, Giovanni

2014-05-01

This paper deals with two important English scientists of the first half of the twentieth century: Edward Arthur Milne and James Hopwood Jeans. It examines the philosophical reasons that, in 1932, induced Milne to devote himself to the newborn modern cosmology. Among those reasons, it is argued that the most important ones were some of Jeans' philosophical statements regarding the new relativistic view of the expanding universe. In particular, Milne reacted to some confusing idealist opinions expressed by Jeans in the London newspaper The Times, in May 1932, in a debate on the expansion of the universe. Actually, as it will be shown, Jeans received many criticisms about the philosophical reasonings present in all of his popularizing works.

Physical interpretation of Jeans instability in quantum plasmas

Akbari-Moghanjoughi, M.; International Centre for Advanced Studies in Physical Sciences and Institute for Theoretical Physics, Ruhr University Bochum, D-44780 Bochum

In this paper, we use the quantum hydrodynamics and its hydrostatic limit to investigate the newly posed problem of Jeans instability in quantum plasmas from a different point of view in connection with the well-known Chandrasekhar mass-limit on highly collapsed degenerate stellar configurations. It is shown that the hydrodynamic stability of a spherically symmetric uniform quantum plasma with a given fixed mass is achieved by increase in its mass-density or decrease in the radius under the action of gravity. It is also remarked that for masses beyond the limiting Jeans-mass, the plasma becomes completely unstable and the gravitational collapse wouldmore » proceed forever. This limiting mass is found to depend strongly on the composition of the quantum plasma and the atomic-number of the constituent ions, where it is observed that heavier elements rather destabilize the quantum plasma hydrodynamically. It is also shown that the Chandrasekhar mass-limit for white dwarf stars can be directly obtained from the hydrostatic limit of our model.« less

A New Method to Directly Measure the Jeans Scale of the Intergalactic Medium Using Close Quasar Pairs

NASA Astrophysics Data System (ADS)

Rorai, Alberto; Hennawi, Joseph F.; White, Martin

2013-10-01

Although the baryons in the intergalactic medium (IGM) trace dark matter fluctuations on megaparsec scales, on smaller scales ~100 kpc, fluctuations are suppressed because the finite temperature gas is pressure supported against gravity, analogous to the classical Jeans argument. This Jeans filtering scale, which quantifies the small-scale structure of the IGM, has fundamental cosmological implications. First, it provides a thermal record of heat injected by ultraviolet photons during cosmic reionization events, and thus constrains the thermal and reionization history of the universe. Second, the Jeans scale determines the clumpiness of the IGM, a critical ingredient in models of cosmic reionization. Third, it sets the minimum mass scale for gravitational collapse from the IGM, and hence plays a pivotal role in galaxy formation. Unfortunately, it is extremely challenging to measure the Jeans scale via the standard technique of analyzing purely longitudinal Lyα forest spectra, because the thermal Doppler broadening of absorption lines along the line-of-sight, is highly degenerate with Jeans smoothing. In this work, we show that the Jeans filtering scale can be directly measured by characterizing the coherence of correlated Lyα forest absorption in close quasar pairs, with separations small enough ~100 kpc to resolve it. We present a novel technique for this purpose, based on the probability density function (PDF) of phase angle differences of homologous longitudinal Fourier modes in close quasar pair spectra. A Bayesian formalism is introduced based on the phase angle PDF, and Markov Chain Monte Carlo techniques are used to characterize the precision of a hypothetical Jeans scale measurement, and explore degeneracies with other thermal parameters governing the IGM. A semi-analytical model of the Lyα forest is used to generate a large grid (500) of thermal models from a dark matter only simulation. Our full parameter study indicates that a realistic sample of only

PubMed

2011-01-01

Jean-Marie Blancou was born in Bangui on 28 August 1936 and passed away in Paris on 10 November 2010 at the age of 74. After studying at the Pierre de Fermat Lycée in Toulouse, Jean Blancou graduated from the Toulouse Veterinary School in 1960. He continued his studies in tropical veterinary medicine in Paris until 1963, extending his knowledge of immunology, microbiology, biochemistry and zoology, at the Institut Pasteur. He obtained his doctorate in biological sciences at the University of Nancy in 1982. Jean Blancou commenced his career as technical adviser to the Veterinary Services of Ethiopia where he directed a campaign against rinderpest in the south of the county. From 1965 to 1967 he was deputy director of the national veterinary laboratory in Niamey where he was responsible for the diagnosis of animal diseases and the production of veterinary vaccines. In 1967, he moved to the central livestock laboratory in Madagascar, where he commenced research on the diagnosis and control of dermatophilosis, bovine tuberculosis and other bacterial and parasitic diseases. In August 1968 he married Geneviève Orue. In 1975 he was appointed as head of the national veterinary laboratory in Senegal, where he remained until 1977. Initially deputy director, and then director of Research on rabies and wildlife diseases, at the World Health Organization collaborating centre in Nancy, he remained in this position until 1990. Jean Blancou was recognised as a world authority on rabies. He conducted research into the diagnosis, aetiology, epidemiology and control of rabies during his time in Nancy. Between 1988 and 1990, Dr Blancou also headed the animal health and protection department of the Centre national d'études vétérinaires et animales (CNEVA) in Maisons-Alfort. On 1 January 1991, he was appointed director general of the World Organisation for Animal Health (Office International des Épizooties: OIE) and was re-elected in 1995 for a further five-year term, until he

A grouping of four bentonite beds, herein named the Government Draw Bentonite Beds, is identified as a stratigraphic marker within the Virgin Creek Member of the Pierre Shale. The beds are found west of Pierre, South Dakota, over an area of at least 130 mi2 (210 km2) where no other markers within the Virgin Creek Member have been identified. In this area, the Government Draw is a potential tool needed to determine the stratigraphic and structural relationships within the upper part of the Pierre Shale, heretofore little known. A better understanding of structural elements found in the Pierre Shale is needed to unravel the Late Cretaceous and younger geologic history of the area. -Authors

Effect of polarization force on the Jeans instability in collisional dusty plasmas

NASA Astrophysics Data System (ADS)

A, ABBASI; M, R. RASHIDIAN VAZIRI

2018-03-01

The Jeans instability in collisional dusty plasmas has been analytically investigated by considering the polarization force effect. Instabilities due to dust-neutral and ion-neutral drags can occur in electrostatic waves of collisional dusty plasmas with self-gravitating particles. In this study, the effect of gravitational force on heavy dust particles is considered in tandem with both the polarization and electrostatic forces. The theoretical framework has been developed and the dispersion relation and instability growth rate have been derived, assuming the plane wave approximation. The derived instability growth rate shows that, in collisional dusty plasmas, the Jeans instability strongly depends on the magnitude of the polarization force.

Exergy analysis of helium liquefaction systems based on modified Claude cycle with two-expanders

NASA Astrophysics Data System (ADS)

Thomas, Rijo Jacob; Ghosh, Parthasarathi; Chowdhury, Kanchan

2011-06-01

Large-scale helium liquefaction systems, being energy-intensive, demand judicious selection of process parameters. An effective tool for design and analysis of thermodynamic cycles for these systems is exergy analysis, which is used to study the behavior of a helium liquefaction system based on modified Claude cycle. Parametric evaluation using process simulator Aspen HYSYS® helps to identify the effects of cycle pressure ratio and expander flow fraction on the exergetic efficiency of the liquefaction cycle. The study computes the distribution of losses at different refrigeration stages of the cycle and helps in selecting optimum cycle pressures, operating temperature levels of expanders and mass flow rates through them. Results from the analysis may help evolving guidelines for designing appropriate thermodynamic cycles for practical helium liquefaction systems.

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

Effect of rotation on Jeans instability of magnetized radiative quantum plasma

NASA Astrophysics Data System (ADS)

Joshi, H.; Pensia, R. K.

2017-03-01

The influence of rotation on the Jeans instability of homogeneous magnetized radiative quantum plasma is investigated. The basic equations of the problem are constructed and linearized by using the Quantum Magnetohydrodynamics (QMHD) model. The general dispersion relation is obtained by using the normal mode analysis technique, which is reduced for both the transverse and the longitudinal mode of propagations and further it is reduced for the axis of rotation parallel and perpendicular to the magnetic field. We found that the stabilizing effects of rotation are decreases for a strong magnetic field which is shown in the graphical representation. We also found that the quantum correction modified the condition of Jeans instability in both modes of propagation. The stabilizing effect of rotation is more increased in the presence of quantum correction.

Pierre Robin sequence is characterized by mandibular retrognathia and glossoptosis resulting in airway obstruction and feeding difficulties. When conservative management fails, mandibular distraction osteogenesis or tongue-lip adhesion may be required to avoid tracheostomy. The authors' goal was to prospectively evaluate the airway and feeding outcomes of their comprehensive approach to Pierre Robin sequence, which includes conservative management, mandibular distraction osteogenesis, and tongue-lip adhesion. A longitudinal study of newborns with Pierre Robin sequence treated at a pediatric academic medical center between 2010 and 2015 was performed. Baseline feeding and respiratory data were collected. Patients underwent conservative management if they demonstrated sustainable weight gain without tube feeds, and if their airway was stable with positioning alone. Patients who required surgery underwent tongue-lip adhesion or mandibular distraction osteogenesis based on family and surgeon preference. Postoperative airway and feeding data were collected. Twenty-eight patients with Pierre Robin sequence were followed prospectively. Thirty-two percent had a syndrome. Ten underwent mandibular distraction osteogenesis, eight underwent tongue-lip adhesion, and 10 were treated conservatively. There were no differences in days to extubation or discharge, change in weight percentile, requirement for gastrostomy tube, or residual obstructive sleep apnea between the three groups. No patients required tracheostomy. The greatest reduction in apnea-hypopnea index occurred with mandibular distraction osteogenesis, followed by tongue-lip adhesion and conservative management. Careful selection of which patients with Pierre Robin sequence need surgery, and of the most appropriate surgical procedure for each patient, can minimize the need for postprocedure tracheostomy. A comprehensive approach to Pierre Robin sequence that includes conservative management, mandibular distraction

Search for Ultra-High Energy Photons with the Pierre Auger Observatory

DOE Office of Scientific and Technical Information (OSTI.GOV)

Homola, Piotr

One of key scientific objectives of the Pierre Auger Observatory is the search for ultra-high energy photons. Such photons could originate either in the interactions of energetic cosmic-ray nuclei with the cosmic microwave background (so-called cosmogenic photons) or in the exotic scenarios, e.g. those assuming a production and decay of some hypothetical super-massive particles. The latter category of models would imply relatively large fluxes of photons with ultra-high energies at Earth, while the former, involving interactions of cosmic-ray nuclei with the microwave background - just the contrary: very small fractions. The investigations on the data collected so far in themore » Pierre Auger Observatory led to placing very stringent limits to ultra-high energy photon fluxes: below the predictions of the most of the exotic models and nearing the predicted fluxes of the cosmogenic photons. In this paper the status of these investigations and perspectives for further studies are summarized.« less

The effect of finite Larmor radius corrections on Jeans instability of quantum plasma

DOE Office of Scientific and Technical Information (OSTI.GOV)

Sharma, Prerana; Chhajlani, R. K.

2013-09-15

The influence of finite Larmor radius (FLR) effects on the Jeans instability of infinitely conducting homogeneous quantum plasma is investigated. The quantum magnetohydrodynamic (QMHD) model is used to formulate the problem. The contribution of FLR is incorporated to the QMHD set of equations in the present analysis. The general dispersion relation is obtained analytically using the normal mode analysis technique which is modified due to the contribution of FLR corrections. From general dispersion relation, the condition of instability is obtained and it is found that Jeans condition is modified due to quantum effect. The general dispersion relation is reduced formore » both transverse and longitudinal mode of propagations. The condition of gravitational instability is modified due to the presence of both FLR and quantum corrections in the transverse mode of propagation. In longitudinal case, it is found to be unaffected by the FLR effects but modified due to the quantum corrections. The growth rate of Jeans instability is discussed numerically for various values of quantum and FLR corrections of the medium. It is found that the quantum parameter and FLR effects have stabilizing influence on the growth rate of instability of the system.« less

Tribute to Jean-Marie Mariotti

Lena, Pierre J.

2003-02-01

Jean-Marie Mariotti (1955 - 1998) prematurely passed away after too short a career of optician and astronomer. With his students, his contributions to the nascent field of high angular resolution at optical wavelengths, and especially to interferometry, both on the ground and in space, have been remarkable. Pioneering the use of single-mode optical fibers and integrated optics, he pushed the accuracy of visibility (amplitude) measurements to a fraction of a percent. His vision of a Mauna Kea kilometric interferometer using the existing giant telescopes is now becoming a reality with the 'OHANA project. His role in the emergence of the Very Large Telescope Interferometer (VLTI) and in the birth of the space mission DARWIN for exoplanets studies has been essential.

A case of undeclared debt? Claude Lévi-Strauss' ambiguities and paradoxes toward analytical psychology.

PubMed

Serina, Florent

2018-06-09

If his relationship to Sigmund Freud's psychoanalysis has been widely acknowledged, Claude Lévi-Strauss' rapport with C.G. Jung's analytical psychology remains quite obscure. While secondary commentary has been abundant, its approach has above all been intertextual, to the detriment of a rigorously historical reading. Even if certain arguments put forward by supporters of so-called "influence" deserve to be taken into account, especially because they highlight Lévi-Strauss ambiguities and paradoxes toward Jung, this paper provides proof that a precise reading of the texts, with the help of recent studies on the intellectual genesis of Lévi-Strauss, lead to reject the thesis of an unstated debt owed by the French anthropologist to the Zurich psychologist. © 2018 Wiley Periodicals, Inc.

This paper presents closed-form solutions for consolidation of transversely isotropic porous media under hydrostatic stress. The solutions are applied to model the time variation of pore pressure, volume strain and strains parallel and normal to bedding, and to obtain coefficients of consolidation and permeability, as well as other properties, and the bulk modulus resulting from hydrostatic consolidation of Pierre shale. It is found that the coefficients consolidation and permeability decrease and the bulk moduli increase with increasing confining pressure, reflecting the closure of voids in the rock. ?? 1991.

Radio detection of extensive air showers at the Pierre Auger Observatory

NASA Astrophysics Data System (ADS)

Berat, C.

2013-08-01

The Pierre Auger Observatory explores the potential of radio-detection techniques to measure extensive air showers (EAS) induced by ultra-high energy cosmic rays. To study in detail the mechanisms responsible for radio emission in the MHz range, the Auger Engineering Radio Array has been installed at the Observatory. Presently consisting of 24 radio-detection stations, this number will grow to 150 units covering an area of almost 20 km2. Novel detection techniques based on the GHz emission from the EAS are currently being studied. AMBER (Air-shower Microwave Bremsstrahlung Experimental Radiometer) and MIDAS (Microwave Detection of Air Showers) are prototypes for a large imaging dish antenna. In EASIER (Extensive Air Shower Identification using Electron Radiometer), the microwave emission is detected by antenna horns located on each surface detector. MIDAS is a self-triggering system while AMBER and EASIER use the trigger from the Auger detectors to record the emission. The status of these radio-detection R&D efforts at the Pierre Auger Observatory will be reported.

This review aims to commemorate the life, and the accomplishments of Pierre and Marie Curie in Physics and in Medicine. Although they are primarily known for their discoveries of the elements of radium and polonium, which took place two years after the discovery of radioactivity by Henry Becquerel, Pierre's discovery of the piezo-electric phenomenon, his research on crystal symmetry, magnetism and paramagnetic substances, are equally important. With the discovery of the two radioactive elements, Pierre and Marie Curie established the new field of Nuclear Physics. It is not an over-statement to say that their discovery contributed much to our modern way of life. Marie received the Nobel Prize twice and later she became the first woman to become member of the French Academy of Sciences. Today, both Pierre and Marie Curie rest in Panthéon, in Paris.

René Nicolas Dufriche Desgenettes (1762-1837) became famous through two historical events: the first and most famous one is where he proved his courage by inoculating himself with the plague during the Syrian campaign in 1799; the second one, rarely represented in paintings, happened during the Russian retreat in 1812 when he was freed thanks to his reputation. Two wide fresco paintings facing each other in the hall of Desgenettes, a hospital built during World War Two, are witnesses of these two major events. Jean Coquet (1907-1990), a decorator, painter and glassblower, who worked at the Beaux-Arts School of Lyon, first as a decoration teacher than as its director, painted these two works of art. In 1946, he inserted them into an ornamental group constituted of ironworks, furniture, stained glass and ceramics. Two paintings from Antoine-Jean Gros (1771-1835) inspired these works: Bonaparte visiting the plague-stricken of Jaffa (1804) and Napoleon on the battlefield of Eylau (1808). With their academic composition and daring stylization those two frescoes represent in a modern and original way Desgenettes' life style, an archetype of what the military doctor is.

Pierre-Joseph Macquer: Chemistry in the French Enlightenment.

PubMed

Lehman, Christine

2014-01-01

Despite recent studies of chemistry courses and of academic research at the beginning of the eighteenth century, the perception of chemistry in the French Enlightenment has often been overshadowed by Lavoisier's works. This article proposes three specific case studies selected from Pierre Joseph Macquer's (1718-84) rich career to show the continuous evolution of chemistry throughout the century: medicinal chemistry through the application of the Comte de La Garaye's metallic salt solutions, the emergence of industrial chemistry through a few of Macquer's evaluations at the Bureau du Commerce, and finally communal academic research through the experiments on diamonds using Tschirnhaus's lens. These examples attempt to illustrate the innovative, creative, dynamic, multicultural, and multifaceted chemistry of the Enlightenment.

Bange, Christian

Claude Bernard was one of the founder of the Société de Biologie created in 1849. He actively took part to it from its very beginning by presenting various communications and several important memoirs. Epistemological thoughts found in these memoirs lead to the methodological chapters introducing the volumes of his edited lessons given at the Collège de France. In 1865, these texts formed the basis to his Introduction à l'étude de la Médecine expérimentale, in which Bernard claims the experimental method should rely on the principle of determinism of the phenomena of Life. He was a dutiful President of the Société from 1867 until his death. He nevertheless was not often involved in debates, but agreed on the defense of the scientific principles he had claimed. He remained influential until his death, as noted in 1899 by the report Engène Gley wrote on the Société de Biologie during its fifty first years. Gley points regularly to Bernard's axioms which remained the true scientific credo of French biologists.

Re-examining Distal Facies of the Grand Bay Ignimbrite at Fond St. Jean, Dominica

NASA Astrophysics Data System (ADS)

Ebner, N.; Frey, H. M.; Wirth, K. R.; Waters, L. E.; Manon, M. R. F.

2017-12-01

The Grand Bay ignimbrite in southern Dominica is a relatively young (43 ± 13 ka by U-Th of zircon), voluminous (0-.5-1 km3 on-land) and laterally extensive pyroclastic flow deposit spanning over 20 km2 that has been associated with the Micotrin volcanic center or Plat Pays complex. The Grand Bay ignimbrite typically occurs as a massive valley fill facies, approximately 9-14 meters thick, exposed on the southern coastal road, rich in white-light gray, relatively crystal rich (25-31%) andesitic (62-63.5 wt% SiO2, 16.7 wt% Al2O3, 6.5 wt % Fe2O3) pumice, whose mineral assemblage is dominated by plagioclase (22-25%), orthopyroxene (3-4%), and clinopyroxene (1-1.5%), in an unconsolidated gray ashy matrix. In the literature, distal facies of the Grand Bay ignimbrite have been proposed at Fond St. Jean (FSJ), but this supposition has recently been called into question. The 9 m thick stratified Fond St. Jean ignimbrite, (38,890 k.a. ± 600 B.P. by14C), is weathered yellow orange and overlies a 4 m thick lithified beach deposit on a sharp contact. Andesitic pumice clasts (60.5-64.5 wt% SiO2, 18 wt% Al2O3, 5.5 wt % Fe2O3) from the base of the FSJ ignimbrite contain similar mineral assemblages to Grand Bay clasts, however, FSJ pumices are relatively less crystal-rich (16-19%), contain significantly less plagioclase (13-16%), opx (1.0-1.5%), cpx (0.1 - 0.6%), and, most strikingly, up to 1% hornblende, which was not present in any Grand Bay samples. The lowermost three meters of the FSJ ignimbrite sequence is composed of meter thick sections of clast (5-7 cm pumice and ≤1 cm lithics) supported beds (70 cm), grading upwards into 30 cm of ash laminations and small pumice clasts (1-3 cm). Following a 40 cm bed of massive ash containing 1-3 cm clasts of pumice, the initial sequence repeats itself for 5 meters, with 30-40 cm lithic blocks in the uppermost unit. In addition to the stark stratigraphic and petrographic differences from the Grand Bay Beach exposure, Fe-Ti oxide

An investigation of the properties of linear stability is conducted for a system consisting of particles having mass m and charge q, interacting through the gravitational and electrostatic force (Jeans instability). However, in light of recent works showing that dust particles in a plasma can have a Lennard-Jones-like shielding potential, a new set of equations has been derived, where the electrostatic interaction among the dust particles is Lennard-Jones-like instead of Coulomb-like. A new condition for the gravitational instability is derived, showing a broader spectrum of unstable modes with faster growth rates.

The early evolution of Jean Piaget's clinical method.

Mayer, Susan Jean

2005-11-01

This article analyzes the early evolution of Jean Piaget's renowned "clinical method" in order to investigate the method's strikingly original and generative character. Throughout his 1st decade in the field, Piaget frequently discussed and justified the many different approaches to data collection he used. Analysis of his methodological progression during this period reveals that Piaget's determination to access the genuine convictions of children eventually led him to combine 3 distinct traditions in which he had been trained-naturalistic observation, psychometrics, and the psychiatric clinical examination. It was in this amalgam, first evident in his 4th text, that Piaget discovered the clinical dynamic that would drive the classic experiments for which he is most well known.

3-D Perspective View, Miquelon and Saint Pierre Islands

NASA Technical Reports Server (NTRS)

2000-01-01

This image shows Miquelon and Saint Pierre Islands, located south of Newfoundland, Canada. These islands, along with five smaller islands, are a self-governing territory of France. North is in the top right corner of the image. The island of Miquelon, in the background, is divided by a thin barrier beach into Petite Miquelon on the left, and Grande Miquelon on the right. Saint Pierre Island is seen in the foreground. The maximum elevation of this land is 240 meters (787 feet). The land mass of the islands is about 242square kilometers (94 square miles) or 1.5 times the size of Washington, DC.

This three-dimensional perspective view is one of several still photographs taken from a simulated flyover of the islands. It shows how elevation data collected by the Shuttle Radar Topography Mission (SRTM) can be used to enhance other satellite images. Color and natural shading are provided by a Landsat 7 image taken on September 7, 1999. The Landsat image was draped over the SRTM data. Terrain perspective and shading are from SRTM. The vertical scale has been increased six times to make it easier to see the small features. This also makes the sea cliffs around the edges of the islands look larger. In this view the capital city of Saint Pierre is seen as the bright area in the foreground of the island. The thin bright line seen in the water is a breakwater that offers some walled protection for the coastal city.

Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on February 11,2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, installed additional C-band and X-band antennas, and

Jeans Instability of the Self-Gravitating Viscoelastic Ferromagnetic Cylinder with Axial Nonuniform Rotation and Magnetic Field

NASA Astrophysics Data System (ADS)

Dhiman, Joginder Singh; Sharma, Rajni

2017-12-01

The effects of nonuniform rotation and magnetic field on the instability of a self gravitating infinitely extending axisymmetric cylinder of viscoelastic ferromagnetic medium have been studied using the Generalised Hydrodynamic (GH) model. The non-uniform magnetic field and rotation are acting along the axial direction of the cylinder and the propagation of the wave is considered along the radial direction, while the ferrofluid magnetization is taken collinear with the magnetic field. A general dispersion relation representing magnetization, magnetic permeability and viscoelastic relaxation time parameters is obtained using the normal mode analysis method in the linearized perturbation equation system. Jeans criteria which represent the onset of instability of self gravitating medium are obtained under the limits; when the medium behaves like a viscous liquid (strongly coupled limit) and a Newtonian liquid (weakly coupled limit). The effects of various parameters on the Jeans instability criteria and on the growth rate of self gravitating viscoelastic ferromagnetic medium have been discussed. It is found that the magnetic polarizability due to ferromagnetization of medium marginalizes the effect of non-uniform magnetic field on the Jeans instability, whereas the viscoelasticity of the medium has the usual stabilizing effect on the instability of the system. Further, it is found that the cylindrical geometry is more stable than the Cartesian one. The variation of growth rate against the wave number and radial distance has been depicted graphically.

2015-11-01

We combine previously published interferometric and single-dish data of relatively nearby massive dense cores that are actively forming stars to test whether their `fragmentation level' is controlled by turbulent or thermal support. We find no clear correlation between the fragmentation level and velocity dispersion, nor between the observed number of fragments and the number of fragments expected when the gravitationally unstable mass is calculated including various prescriptions for `turbulent support'. On the other hand, the best correlation is found for the case of pure thermal Jeans fragmentation, for which we infer a core formation efficiency around 13 per cent, consistent with previous works. We conclude that the dominant factor determining the fragmentation level of star-forming massive dense cores at 0.1 pc scale seems to be thermal Jeans fragmentation.

Numerical modeling of the traction process in the treatment for Pierre-Robin Sequence.

PubMed

Słowiński, Jakub J; Czarnecka, Aleksandra

2016-10-01

The goal of this numerical study was to identify the results of modulated growth simulation of the mandibular bone during traction in Pierre-Robin Sequence (PRS) treatment. Numerical simulation was conducted in the Ansys 16.2 environment. Two FEM (finite elements method) models of a newborn's mandible (a spatial and a flat model) were developed. The procedure simulated a 20-week traction period. The adopted growth measure was mandibular length increase, defined as the distance between the Co-Pog anatomic points used in cephalometric analysis. The simulation calculations conducted on the developed models showed that modulation had a significant influence on the pace of bone growth. In each of the analyzed cases, growth modulation resulted in an increase in pace. The largest value of increase was 6.91 mm. The modulated growth with the most beneficial load variant increased the basic value of the growth by as much as 24.6%, and growth with the least beneficial variant increased by 7.4%. Traction is a simple, minimally invasive and inexpensive procedure. The proposed algorithm may enable the development of a helpful forecasting tool, which could be of real use to doctors working on Pierre-Robin Sequence and other mandibular deformations in children.

Lehmann, H C; Hartung, H-P; Kieseier, B C

2004-02-01

Jean-Martin Charcot (1825-1893), well known as the founder of modern neurology, was the most celebrated neurologist in the nineteenth century. His international success stemmed not only from mastery descriptions of various neurological disorders but also from his many contacts with scientists all over the world. The aim of this article is to review Charcot's ambivalent relationship to German neuropsychiatry of the time and to examine the German reception of his personality and work. Wilhelm Erb, Ludwig Hirt, Ernst von Leyden, Max Nonne, Adolph Strümpell, and other German physicians cultivated -to varying degrees - professional contacts with Charcot and, based on the fascination of his personality and significance of his work, were long and intensively influenced by the Salpêtrière school. The extent of their admiration became apparent in 1882 by the award of an honorary doctorate to Charcot by the University of Würzburg. Along with increasingly severe criticism of Charcot's research on hysteria and hypnosis, most German neuropsychiatrists became estranged, without neglecting his importance to the development of neurology in Germany.

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

Jean Rotz and the Marine Chart, 1542

NASA Astrophysics Data System (ADS)

Taylor, E. G. R.

This paper was first published in the Journal in 1954 (Vol. 7, p. 138). It is followed by comments from Michael Richey.At the time (1542) when Jean Rotz presented Henry VIII with a variation compass, and an accompanying treatise on its making and use, the question of magnetic variation was an acute one. It formed part of a wider controversy concerning the general validity of the sea-chart which had been raised among seamen. As to this, Dr Pedro Nunez, writing a treatise in 1537 addressed to his friend and pupil the Infante Dom Luys of Portugal, said that there were skilled pilots who derided the chart and declared it to be - the falsest thing in the world. Hastening to its defence, Nunez dealt at length with the navigating errors introduced by ignoring the convergence of the meridians, and showed besides that a rhumb, or line of constant bearing was a spiral curve on the globe.

Jeans that fit: weighing the mass of the Milky Way analogues in the ΛCDM universe

NASA Astrophysics Data System (ADS)

Kafle, Prajwal R.; Sharma, Sanjib; Robotham, Aaron S. G.; Elahi, Pascal J.; Driver, Simon P.

2018-04-01

The spherical Jeans equation is a widely used tool for dynamical study of gravitating systems in astronomy. Here, we test its efficacy in robustly weighing the mass of Milky Way analogues, given they need not be in equilibrium or even spherical. Utilizing Milky Way stellar haloes simulated in accordance with Λ cold dark matter (ΛCDM) cosmology by Bullock and Johnston and analysing them under the Jeans formalism, we recover the underlying mass distribution of the parent galaxy, within distance r/kpc ∈ [10, 100], with a bias of ˜ 12 per cent and a dispersion of ˜ 14 per cent. Additionally, the mass profiles of triaxial dark matter haloes taken from the SURFS simulation, within scaled radius 0.2 < r/rmax < 3, are measured with a bias of ˜ - 2.4 per cent and a dispersion of ˜ 10 per cent. The obtained dispersion is not because of Poisson noise due to small particle numbers as it is twice the later. We interpret the dispersion to be due to the inherent nature of the ΛCDM haloes, for example being aspherical and out-of-equilibrium. Hence, the dispersion obtained for stellar haloes sets a limit of about 12 per cent (after adjusting for random uncertainty) on the accuracy with which the mass profiles of the Milky Way-like galaxies can be reconstructed using the spherical Jeans equation. This limit is independent of the quantity and quality of the observational data. The reason for a non-zero bias is not clear, hence its interpretation is not obvious at this stage.

When the Jeans Do Not Fit: How Stellar Feedback Drives Stellar Kinematics and Complicates Dynamical Modeling in Low-mass Galaxies

DOE Office of Scientific and Technical Information (OSTI.GOV)

El-Badry, Kareem; Quataert, Eliot; Wetzel, Andrew R.

In low-mass galaxies, stellar feedback can drive gas outflows that generate non-equilibrium fluctuations in the gravitational potential. Using cosmological zoom-in baryonic simulations from the Feedback in Realistic Environments project, we investigate how these fluctuations affect stellar kinematics and the reliability of Jeans dynamical modeling in low-mass galaxies. We find that stellar velocity dispersion and anisotropy profiles fluctuate significantly over the course of galaxies’ starburst cycles. We therefore predict an observable correlation between star formation rate and stellar kinematics: dwarf galaxies with higher recent star formation rates should have systemically higher stellar velocity dispersions. This prediction provides an observational test ofmore » the role of stellar feedback in regulating both stellar and dark-matter densities in dwarf galaxies. We find that Jeans modeling, which treats galaxies as virialized systems in dynamical equilibrium, overestimates a galaxy’s dynamical mass during periods of post-starburst gas outflow and underestimates it during periods of net inflow. Short-timescale potential fluctuations lead to typical errors of ∼20% in dynamical mass estimates, even if full three-dimensional stellar kinematics—including the orbital anisotropy—are known exactly. When orbital anisotropy is not known a priori, typical mass errors arising from non-equilibrium fluctuations in the potential are larger than those arising from the mass-anisotropy degeneracy. However, Jeans modeling alone cannot reliably constrain the orbital anisotropy, and problematically, it often favors anisotropy models that do not reflect the true profile. If galaxies completely lose their gas and cease forming stars, fluctuations in the potential subside, and Jeans modeling becomes much more reliable.« less

KENNEDY SPACE CENTER, FLA. -- STS-84 Mission Specialist Jean- Francois Clervoy prepares to enter the Space Shuttle Atlantis at Launch Pad 39A with help from white room closeout crew members. The fourth Shuttle mission of 1997 will be the sixth docking of the Space Shuttle with the Russian Space Station Mir. The commander is Charles J. Precourt. The pilot is Eileen Marie Collins. The five mission specialists are C. Michael Foale, Carlos I. Noriega, Edward Tsang Lu, Jean-Francois Clervoy of the European Space Agency and Elena V. Kondakova of the Russian Space Agency. The planned nine-day mission will include the exchange of Foale for U.S. astronaut and Mir 23 crew member Jerry M. Linenger, who has been on Mir since Jan. 15. Linenger transferred to Mir during the last docking mission, STS-81; he will return to Earth on Atlantis. Foale is slated to remain on Mir for about four months until he is replaced in September by STS-86 Mission Specialist Wendy B. Lawrence. During the five days Atlantis is scheduled to be docked with the Mir, the STS-84 crew and the Mir 23 crew, including two Russian cosmonauts, Commander Vasily Tsibliev and Flight Engineer Alexander Lazutkin, will participate in joint experiments. The STS-84 mission also will involve the transfer of more than 7,300 pounds of water, logistics and science equipment to and from the Mir. Atlantis is carrying a nearly 300-pound oxygen generator to replace one of two Mir units which have experienced malfunctions. The oxygen it generates is used for breathing by the Mir crew.

Evolution of the phase-space density and the Jeans scale for dark matter derived from the Vlasov-Einstein equation

Piattella, O.F.; Rodrigues, D.C.; Fabris, J.C.

We discuss solutions of Vlasov-Einstein equation for collisionless dark matter particles in the context of a flat Friedmann universe. We show that, after decoupling from the primordial plasma, the dark matter phase-space density indicator Q = ρ/(σ{sub 1D}{sup 2}){sup 3/2} remains constant during the expansion of the universe, prior to structure formation. This well known result is valid for non-relativistic particles and is not ''observer dependent'' as in solutions derived from the Vlasov-Poisson system. In the linear regime, the inclusion of velocity dispersion effects permits to define a physical Jeans length for collisionless matter as function of the primordial phase-spacemore » density indicator: λ{sub J} = (5π/G){sup 1/2}Q{sup −1/3}ρ{sub dm}{sup −1/6}. The comoving Jeans wavenumber at matter-radiation equality is smaller by a factor of 2-3 than the comoving wavenumber due to free-streaming, contributing to the cut-off of the density fluctuation power spectrum at the lowest scales. We discuss the physical differences between these two scales. For dark matter particles of mass equal to 200 GeV, the derived Jeans mass is 4.3 × 10{sup −6}M{sub ⊙}.« less

Estimation of the Invisible Energy in Extensive Air Showers with the Data Collected by the Pierre Auger Observatory

NASA Astrophysics Data System (ADS)

Mariazzi, Analisa

The determination of the energy of primary cosmic rays from their extensive air showers using the fluorescence technique requires an estimation of the energy carried away by particles reaching the ground that do not deposit all their energy in the atmosphere. This estimation is typically made using Monte Carlo simulations and depends on the assumed primary particle mass and on model predictions for hadron-air collisions at high energies. In this work we review the method that the Pierre Auger Collaboration uses to obtain the invisible energy directly from hybrid events measured simultaneously with the fluorescence and the surface detectors of the Pierre Auger Observatory. As a corroboration of these results, a new method for the determination of the invisible energy using an independent data set is also presented. Both methods agree within systematic uncertainties, reducing significantly the biases related to differences between the high energy hadronic interaction models and data.

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

Numerical modeling of a long-term in situ chemical osmosis experiment in the Pierre Shale, South Dakota

2006-01-01

We have numerically modeled evolving fluid pressures and concentrations from a nine-year in situ osmosis experiment in the Pierre Shale, South Dakota. These data were obtained and recently interpreted by one of us (C.E.N.) as indicating a potentially significant role for chemical osmosis in media like the Pierre Shale. That analysis considered only the final pressure differentials among boreholes that were assumed to represent osmotic equilibrium. For this study, the system evolution was modeled using a recently developed transient model for membrane transport. The model simulates hydraulically and chemically driven fluid and solute transport. The results yield an estimate of the thickness of the water film between the clay platelets b of 40 A??, which corresponds to an osmotic efficiency ?? of 0.21 for the ambient pore water salinity of 3.5 g/l TDS. These values largely confirm the results of the earlier equilibrium analysis. However, the new model analysis provides additional constraints suggesting that intrinsic permeability k = 1.4 ?? 10-19 m2, specific storage Ss = 1.7 ?? 10-5 m-1, and diffusion coefficient D* = 6 ?? 10-11 m2/s. The k value is larger than certain independent estimates which range from 10-21 to 10-20; it may indicate opening of microcracks during the experiments. The fact that the complex transient pressure and concentration behavior for the individual wells could be reproduced quite accurately, and the inferred parameter values appear to be realistic for the Pierre Shale, suggests that the new model is a useful tool for modeling transient coupled flows in groundwater systems. ?? 2005 Elsevier Ltd.

Illness as the saturated phenomenon: the contribution of Jean-Luc Marion.

PubMed

Grīnfelde, Māra

2018-05-24

During the last few decades, many thinkers have advocated for the importance of the phenomenological approach in developing the understanding of the lived experience of illness. In their attempts, they have referred to ideas found in the history of phenomenology, most notably, in the works of Edmund Husserl, Martin Heidegger, Maurice Merleau-Ponty and Jean-Paul Sartre. The aim of this paper is to sketch out an interpretation of illness based on a yet unexplored conceptual framework of the phenomenology of French thinker Jean-Luc Marion. Focusing on concepts of the saturated phenomenon and flesh, the paper develops an interpretation of illness as the saturated phenomenon, which highlights a variety of dimensions of illness already elaborated within the phenomenology of medicine, such as the affective dimension of illness, the disruptive dimension of illness, the transformed perception of the self in illness, mineness of flesh in illness and the inexpressible and hermeneutical dimension of illness. In addition to that, the paper explores some of the consequences the proposed interpretation of illness offers regarding the nature of illness and health. It is argued that illness in its essence is very similar to the experience of other saturated phenomena, suggesting that the difference between them does not lie within the character of the affective givenness, but rather within the dynamic relationship between the affective givenness and its conceptualization. It is also shown that the experience of health is compatible with the experience of saturation and thus is not limited to the tacit and harmonious background state.

From The Pierre Auger Observatory to AugerPrime

Parra, Alejandra; Martínez Bravo, Oscar; Pierre Auger Collaboration

2017-06-01

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

Background We investigated a large family with Pierre Robin sequence (PRS). Aim of the study This study aims to determine the genetic cause of PRS. Results The reciprocal translocation t(4;6)(q22;p21) was identified to be segregated with PRS in a three-generation family. Whole-genome sequencing and Sanger sequencing successfully detected breakpoints in the intragenic regions of BMRP1B and GRM4. We hypothesized that PRS in this family was caused by (i) haploinsufficiency for BMPR1B or (ii) a gain of function mechanism mediated by the BMPR1B-GRM4 fusion gene. In an unrelated family, we identified another BMPR1B-splicing mutation that co-segregated with PRS. Conclusion We detected two BMPR1B mutations in two unrelated PRS families, suggesting that BMPR1B disruption is probably a cause of human PRS. Methods GTG banding, comparative genomic hybridization, whole-genome sequencing, and Sanger sequencing were performed to identify the gene causing PRS. PMID:28418932

Armand-Jean de Mauvillain was Marguerite Cardinal's and Jean de Mauvillain's son. Jean de Mauvillain was successively the King's and Gaston d'Orléans surgeon. His ancestors were native of the Poitou region. The Mauvillains' genealogy has been documented. Armand-Jean de Mauvillain completed his medical studies in Paris and graduated on May 19, 1649. He was appointed "Docteur-régent" on Februrary 3, 1650 and professor of botany in 1655. He was dismissed from his position at the Faculté de médecine for four years due to a quarrel with the Dean Antoine Blondel. Then he resumed his former position and was elected Dean in 1666. In 1650, he married Gemme Cornuty the daughter of the "Docteur-régent" Jacques Cornuty and Anne Bergeret. Jacques Cornuty was the son of Georges Cornuty, a former Dean of the Faculté de médecine (1608-1610). Mauvillain and his wife had four children: Armand-Jean, also future "Docteur-régent", Guillaume, Nicolas and Louise-Angélique.His property inventory enables us to discover his living conditions, his collection of books and the value of his belongings. His role as Molière's counsellor is disputable. The actual date of his first meeting with the famous comedian has not been ascertained. The geneaology of de Mauvillain's family has been documented from the end of the sixteenth century to the middle of the eighteenth century. Its members counted a surgeon, a priest, physicians and lawyers. These commendable activities were in accordance with those traditionally practised by the Ancien Regime middle class members.

As a part of the Geological Survey's program of investigating uranium-bearing carbonaceous rocks on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission, a reconnaissance of the Sharon Springs member of the Pierre shale in western Kansas and eastern Colorado was conducted during 1954. The Sharon Springs member of the Pierre shale and its lateral equivalents ranges from 155 to about 500 feet in thickness and generally contains about 0.001 percent uranium, but some beds contain larger amounts. A 6-foot thick shale bed in Cheyenne County, Colo., contains about 0.006 percent uranium, a 4 1/2-foot thick sequence of beds in Crowley County, Colo., is estimated to contain between 0.004 and 0.005 percent uranium, and a 3 1/2-foot thick sequence of beds in Kiowa County, Colo., contains about 0.004 percent uranium. At several outcrop localities, sequences of beds as much as 9 1/2 feet thick contain about 0.003 percent uranium. Data from wells indicate that the 4 1/2-foot thick sequence of beds in Crowley County, Colo., may have a lateral extent of at least 5 1/2 miles. A gamma-ray log of a well in Yuma County, Colo., indicates the presence of a sequence of beds 66 feet thick which contains 0.005 to 0.010 percent equivalent uranium. No definite pattern of areal distribution of radioactivity and uranium content in the Sharon Springs is indicated by available data. Lateral variation in uranium content of individual beds was not noted in outcrops, which seldom extend more than 150 feet, but subsurface data from gamma-ray logs of wells indicate that both the maximum radioactivity and the thickness of radioactive beds are variable within distances of a few miles. Vertical variation in radioactivity and uranium content of the more radioactive beds is usually abrupt, but in the rocks as a whole the range of uranium content is so small that large variations in content are absent. In most of the gamma-ray logs examined there is only part of the sequence of rocks

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

It is entering its 60th year in 2014. In 1962, the Astronautica Acta became the official Journal of the International Academy of Astronautics (IAA) established in 1960. A total of 18 volumes had been published from 1955 to 1973 under the leadership of three Editor-in-Chiefs: F. Hecht, Theodore von Karman, and Martin Summerfield. In 1974, A.K. Oppenheim became the new Editor-in-Chief and several evolved changes were performed including change of the title to Acta Astronautica (for grammatical correctness), cover page change, and format change. From 1974 to 2010, another three Editor-in-Chiefs led the journal with 67 volumes published. They were A.K. Oppenheim, Jean-Pierre Marec, and Rupert Gerzer. The current Editor-in-Chief Jeng-Shing Chern (Rock) took over the job from 2011. Total pages and articles published in 2012 are 3586 and 356, respectively. Currently, the Acta Astronautica Editorial Board consists of one Editor-in-Chief, 15 Co-Editors, one Managing Editor and one Honorary Editor-in-Chief (Jean-Pierre Marec). After 59 years, the Acta Astronautica has become a well-known journal worldwide. Its current rank and impact factor are 7/63 and 0.701, respectively. This paper presents some of the details as well as new strategies and steps. In particular, supports from the IAA Academicians are mandatory and most welcome.

An analysis of concert saxophone vibrato through the examination of recordings by eight prominent soloists

This study examines concert saxophone vibrato through the analysis of several recordings of standard repertoire by prominent soloists. The vibrato of Vincent Abato, Arno Bornkamp, Claude Delangle, Jean-Marie Londeix, Marcel Mule, Otis Murphy, Sigurd Rascher, and Eugene Rousseau is analyzed with regards to rate, extent, shape, and discretionary use. Examination of these parameters was conducted through both general observation and precise measurements with the aid of a spectrogram. Statistical analyses of the results provide tendencies for overall vibrato use, as well as the effects of certain musical attributes (note length, tempo, dynamic, range) on vibrato. The results of this analysis are also compared among each soloist and against pre-existing theories or findings in vibrato research.

Haemoglobin Pierre-Benite--a high affinity variant associated with relative polycythaemia.

PubMed

Beard, M E; Potter, H C; Spearing, R L; Brennan, S O

2001-12-01

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

2004-03-01

Jean-Dominique Cassini, for whom the Cassini mission to Saturn is named, is best known for his early understanding of that planet's rings. This article is an overview of his influential career in astronomy and other scientific fields.= Born in Italy in1625 and formally educated at an early age, he was a professor of astronomy at the University of Bologna, a leading center of learning in Europe of the time. He was an early observer of Jupiter, Mars, and Venus. He is best known for constructing a giant pinhole camera in a cathedral that he used with a meridian line on the floor to track the Sun's image through the year, thus providing the Catholic Church with a reliable calendar. Cassini also used the pinhole camera observations to calculate the variation in the distance between the Sun and Earth, thus lending support to the Copernican (Sun-centered) view of the solar system. Cassini moved to Paris at the request of King Louis XIV, originally to oversee the surveying needed for a new map system of France, but ultimately he took over as the director of the Paris Observatory. Cassini's descendants ran the observatory there for the following century.

Shaded Relief Image of Saint Pierre and Miquelon

NASA Technical Reports Server (NTRS)

2000-01-01

This image shows two islands, Miquelon and Saint Pierre, located south of Newfoundland, Canada. These islands, along with five smaller islands, are a self-governing territory of France. A thin barrier beach divides Miquelon, with Grande Miquelon to the north and Petite Miquelonto the south. Saint Pierre Island is located to the lower right. With the islandsi location in the north Atlantic Ocean and their deep water ports, fishing is the major part of the economy. The maximum elevation of the island is 240 meters (787 feet). The land mass of the islands is about 242 square kilometers, or 1.5 times the size of Washington DC.

This shaded relief image was generated using topographic data from the Shuttle Radar Topography Mission. A computer-generated artificial light source illuminates the elevation data to produce a pattern of light and shadows. Slopes facing the light appear bright, while those facing away are shaded. On flatter surfaces, the pattern of light and shadows can reveal subtle features in the terrain. Shaded relief maps are commonly used in applications such as geologic mapping and land use planning.

This image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM uses the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. The mission is designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between the National Aeronautics and Space Administration (NASA), the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense (DoD), and the German and Italian space agencies.

Albert-Jean-Louis Brun (1851-1929), was chemist of the University of Bern (Switzerland) and "licencié ès sciences" of the University of Sorbonne (France). In Paris he was a faithful follower of Charles Friedel. In Coutance (Genève), where he was working in his own chemistry, he realised all his researchs. After a trip to Stromboli in 1901, he studied the volcanic phenomena as a chemist, as a mineralogist and as a geophysicist. His researchs brought him till the mediterranean volcanos--Vesuve, Etna, Santorin--, till Java and Krakatoa, then Canarian islands, and the lava lake of Kilauea, etc. The results of his works are collected in a big book called "Recherches sur l'exhalaison volcanique": he presents a theory which was the subject of a polemic with the professor Henri Gautier of the professor Henri Gautier of the Faculty of Pharmacy of Paris.

In this paper we introduce the concept of Lateral Trigger Probability (LTP) function, i.e., the probability for an Extensive Air Shower (EAS) to trigger an individual detector of a ground based array as a function of distance to the shower axis, taking into account energy, mass and direction of the primary cosmic ray. We apply this concept to the surface array of the Pierre Auger Observatory consisting of a 1.5 km spaced grid of about 1600 water Cherenkov stations. Using Monte Carlo simulations of ultra-high energy showers the LTP functions are derived for energies in the range between 1017 and 1019 eV and zenith angles up to 65°. A parametrization combining a step function with an exponential is found to reproduce them very well in the considered range of energies and zenith angles. The LTP functions can also be obtained from data using events simultaneously observed by the fluorescence and the surface detector of the Pierre Auger Observatory (hybrid events). We validate the Monte Carlo results showing how LTP functions from data are in good agreement with simulations.

The Pierre Auger Observatory is a detector for ultra-high energy cosmic rays. It consists of a surface array to measure secondary particles at ground level and a fluorescence detector to measure the development of air showers in the atmosphere above the array. The "hybrid" detection mode combines the information from the two subsystems. We describe the determination of the hybrid exposure for events observed by the fluorescence telescopes in coincidence with at least one water-Cherenkov detector of the surface array. A detailed knowledge of the time dependence of the detection operations is crucial for an accurate evaluation of the exposure. We discuss the relevance of monitoring data collected during operations, such as the status of the fluorescence detector, background light and atmospheric conditions, that are used in both simulation and reconstruction.

STS-103: Flight Day 6 Highlights and Crew Activities Report

1999-01-01

Discovery's astronauts (Mission Commander, Curtis L. Brown; Pilot, Scott J. Kelly; Mission Specialists, Steven L. Smith, C. Michael Foale, and John M. Grunsfeld; and (ESA) Mission Specialists, Claude Nicollier and Jean-Francois Clervoy) deliver a Christmas present to the world, putting the Hubble Space Telescope back into service after 24 hours and 33 minutes of repairs and upgrades that make the orbital observatory more capable than ever. European Space Agency Astronaut Jean-Francois Clervoy uses the shuttle's robot arm to release the telescope at 5:03 p.m. CST, then places the arm into an upright salute as Commander Curt Brown fires Discovery's steering jets to begin separating from the telescope. The telescope's re-deployment takes place at an altitude of 370 statute miles as the two spacecraft fly over the South Pacific's coral sea northeast of Australia. At 5:39 CST, Brown executes a second steering jet burn, lowering Discovery's orbit slightly, so that it will begin orbiting faster than the telescope and move away at just under 6 statute miles per orbit. Afterward, each of the seven astronauts on board calls down holiday wishes from space in several languages.

Jeans instability of inhomogeneous dusty plasma with polarization force, ionization and recombination

The self-gravitational Jeans instability has been studied in dusty plasma containing significant background of neutral pressure and recombination of ions and electrons on the dust surface. The full dynamics of charged dust grains, ions and neutral species are employed considering the electrons as Maxwellian. We have derived the general dispersion relation for collisional dusty plasma with ionization, recombination and polarization force. The general dispersion relation describes the effects of considered parameters which are solved in different dusty plasma situations. Further, the dispersion relation is solved numerically. The present work is applicable to understand the structure formation of interstellar molecular clouds in astrophysical plasma.

Pierre Janet and Félida Artificielle: multiple personality in a nineteenth-century guise.

Brown, Edward M

2003-01-01

In the wake of the recent epidemic of multiple personality phenomena, it is important to get a clear idea of what similar phenomena looked like in previous centuries. Pierre Janet's detailed description of his discovery, made during the 1880s, that he could cure hysteria by creating a healthy second personality offers a close look at a form of multiple personalities very different from what has recently been described. His description of the factors that influenced his discovery allow one to see his work in a historical context and to appreciate his confrontation with the paradoxes that this discovery revealed.

Numerical studies on sizing/ rating of plate fin heat exchangers for a modified Claude cycle based helium liquefier/ refrigerator

NASA Astrophysics Data System (ADS)

Goyal, M.; Chakravarty, A.; Atrey, M. D.

2017-02-01

Performance of modern helium refrigeration/ liquefaction systems depends significantly on the effectiveness of heat exchangers. Generally, compact plate fin heat exchangers (PFHE) having very high effectiveness (>0.95) are used in such systems. Apart from basic fluid film resistances, various secondary parameters influence the sizing/ rating of these heat exchangers. In the present paper, sizing calculations are performed, using in-house developed numerical models/ codes, for a set of high effectiveness PFHE for a modified Claude cycle based helium liquefier/ refrigerator operating in the refrigeration mode without liquid nitrogen (LN2) pre-cooling. The combined effects of secondary parameters like axial heat conduction through the heat exchanger metal matrix, parasitic heat in-leak from surroundings and variation in the fluid/ metal properties are taken care of in the sizing calculation. Numerical studies are carried out to predict the off-design performance of the PFHEs in the refrigeration mode with LN2 pre-cooling. Iterative process cycle calculations are also carried out to obtain the inlet/ exit state points of the heat exchangers.

Jean Martin Charcot (1825-1893) is known as the founder of neurology in France and was one of the most versatile medical researchers of his times. At the climax of his career in the Salpêtrière in Paris he began to study the phenomenon of hysteria. Hysterical symptoms were very common in the late nineteenth century in Europe and were looked upon as a challenge to medical science. By means of accurate observation, Charcot managed to describe the distinct features of hysteria. The disease became an accepted medical entity and patients were less often regarded as simulators. Charcot presumed that the disease had a physical cause, and tried to prove this by means of patho-anatomical studies and later by experiment, with help of hypnosis. Charcot's despotic personality, the extraordinary circumstances at the Salpêtrière and the hysteric patients formed a fascinating setting that gives exemplary insight into the non-linear progress of medical science.

The historic books belonging to the Société Astronomique de France, founded by Camille Flammarion in 1887, are located partly in Paris and partly at the Flammarion site in Juvisy, a Paris suburb. Their holdings include first editions of Copernicus's De Revolutionibus and of Flamsteed's star atlas, as well as Messier's own copy of his 1783 and 1784 papers with his handwritten comments and additions. I will describe the fruitless search for a Bevis atlas and the circumstances that led me to inspect these treasures. I thank David Valls-Gabaud and Philippe Morel of the Société Astronomique de France for their hospitality in Paris, Jean-Claude Pecker, and Owen Gingerich for his prior work on Messier's catalogue.

2016-10-01

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

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

Stereo Reconstruction of ELVES at the Pierre Auger Observatory

Mussa, R.; Tonachini, A. S.

2013-12-01

The Pierre Auger Observatory, located in Malargue (Argentina), is the world's largest facility (3000 km2) for the study of Ultra High Energy Cosmic Rays (E>10^18 eV). The four sites of the Fluorescence Detector (covering a field of view of 30x180 degrees) are continuously observing the night sky with 100 ns time resolution and a space resolution of about 1 degree. In May 2005, the first ELVES candidate was serendipitously observed by the FD, which is designed to detect the electromagnetic component of cosmic ray showers and to reject lightning. Since March 2013, the Auger Observatory has implemented a special trigger dedicated to the detection of ELVES, whose topology (a rapidly evolving ring) is quite different from the one of cosmic ray events. This allows to record events with high efficiency and unprecedented accuracy. The average distance between two eyes, about 40 km, allows stereo imaging of a large fraction of ELVES candidate events. More than 100 ELVES candidates from the first 6 months of data taking will be shown.

Pierre Janet and the enchanted boundary of psychical research.

PubMed

Evrard, Renaud; Pratte, Erika Annabelle; Cardeña, Etzel

2018-05-01

Among the founders of French psychology, Pierre Janet (1859-1947) is recognized for both his scientific and institutional roles. The psychology born at the turn of the 20th century was initially partly receptive to, but then engaged in, a battle with the "psychical marvelous," and Janet was no exception. He was involved in the split between psychology and parapsychology (or "metapsychics" in France), developed at that time, playing several successive roles: the pioneer, the repentant, and the gatekeeper. At first, he was involved in so-called experimental parapsychology, but quickly chose not to engage directly in this kind of research any longer. Janet seemed to become embarrassed by his reputation as psychical researcher, so he increased his efforts to side with the more conventional thought of his time. Janet's attitude, in this, is an example of how French nascent psychology has explored "marvelous phenomena" before recanting. Yet this aspect of Janet's work has been rarely commented on by his followers. In this article, we describe the highlights of his epistemological journey.

In 1710, the surgeon Pierre Dionis publishes a Dissertation on sudden death. Echoing and expanding the work of his Roman colleague Jean Marie Lancisi, he describes and analyzes dozens of cases of sudden death observed by him. A large number of cases was followed by autopsies allowing clinicopathological confrontation. Are proposed causes of death (pulmonary embolism, myocardial infarction, hemorrhagic stroke, arterial rupture, etc.), pathophysiological mechanisms based on the ancient theory of humors, and preventive actions to avoid these unexpected deaths. In this article, we oppose these old data to those of current literature. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Neutrinos in the sub-EeV energy range and above can be detected and identified with the Surface Detector array of the Pierre Auger Observatory. The identification can be efficiently done for neutrinos of all flavours interacting in the atmosphere, typically above 60° (downward-going), as well as for “Earth-skimming” neutrino interactions in the case of tau neutrinos (upward-going). Three sets of identification criteria were designed to search for downward-going neutrinos in the zenith angle bins 60° − 75° and 75° − 90° as well as for upward-going neutrinos. The three searches have been recently combined, providing, in the absence of candidates inmore » data from 1 January 04 until 31 December 12, a stringent limit to the diffuse flux of ultra-high energy neutrinos.« less

The Pierre Auger Observatory is a detector for ultra-high energy cosmic rays. It consists of a surface array to measure secondary particles at ground level and a fluorescence detector to measure the development of air showers in the atmosphere above the array. The 'hybrid' detection mode combines the information from the two subsystems. We describe the determination of the hybrid exposure for events observed by the fluorescence telescopes in coincidence with at least one water-Cherenkov detector of the surface array. A detailed knowledge of the time dependence of the detection operations is crucial for an accurate evaluation of the exposure.more » We discuss the relevance of monitoring data collected during operations, such as the status of the fluorescence detector, background light and atmospheric conditions, that are used in both simulation and reconstruction.« less

We present a search for ultrarelativistic magnetic monopoles with the Pierre Auger observatory. Such particles, possibly a relic of phase transitions in the early Universe, would deposit a large amount of energy along their path through the atmosphere, comparable to that of ultrahigh-energy cosmic rays (UHECRs). The air-shower profile of a magnetic monopole can be effectively distinguished by the fluorescence detector from that of standard UHECRs. No candidate was found in the data collected between 2004 and 2012, with an expected background of less than 0.1 event from UHECRs. The corresponding 90% confidence level (C.L.) upper limits on the flux of ultrarelativistic magnetic monopoles range from 10-19(cm2 sr s )-1 for a Lorentz factor γ =1 09 to 2.5 ×10-21(cm2 sr s )-1 for γ =1 012.

One hundred years after his death, Jean Baptiste Paulin Trolard's name endures in the medical literature primarily because of his work on the anastomotic veins of the cerebral circulation. Specifically, and known to all neurosurgeons, the great anastomotic vein, or the vein of Trolard, underscores a portion of Trolard's contribution to neuroanatomy. The country of Algeria has also remembered this influential colonist because of his life's work as a physician, professor, humanitarian, environmentalist, and French nationalist. Trolard fought deforestation, injustice, epidemics, and bureaucracy in northern Africa and tragically died in the midst of these struggles. In this historical vignette, the authors review the life and contributions of this pioneer of early neuroanatomy.

Jean Marian Purdy remembered - the hidden life of an IVF pioneer.

Gosden, Roger

2018-06-01

Jean Purdy is almost forgotten as one of the British trio that introduced clinical IVF to the world. An unlikely pioneer, she qualified as a nurse but through indefatigable effort and unstinting loyalty to a programme that faced vitriolic opposition she became the clinical embryologist for the first IVF baby. In 1980, she helped to launch fertility services as the 'Technical Director' of Bourn Hall Clinic, near Cambridge. Although Robert Edwards and Patrick Steptoe generously credited her role in research and clinical care, a premature death in 1985 at age 39 robbed her of the reward of witnessing the blossoming of assisted reproductive technologies for patients around the world. This commentary seeks to recognize her contribution and bring her name to the attention of professionals in reproductive medicine and the patients they care for.

This work is registered in the year (2013) commemorating the 120 years since Jean-Martin Charcot's (1825-1893) death. Presently, the event takes place during 2013, in France, in Paris, at Hôpital de la Salpêtrière where Charcot practiced as medical chief of l'Hospice de la Vieillesse-Femmes, from 1862 until he died in 1893. The aim of the research is to show, from various examples and sources (printed and handwritten: fonds d'archives Charcot de la Salpêtrière) how talented Charcot was as a clinician, pathologist and microscopist, researcher and experimenter, teacher, artist, designer, cartoonist, polyglot and traveller), how varied his medical career was and how innovative his scientific method was. All this permitted Charcot to make an impressive number of medical discoveries in various fields which are today known as geriatrics and rheumatology, internal medicine, cardiology, neurology, psychiatry and paranormal processes.

Cosmic rays at the ankle: Composition studies using the Pierre Auger Observatory

NASA Astrophysics Data System (ADS)

Younk, Patrick William

The ankle is a flattening of the cosmic ray energy spectrum at approximately 10 18.5 eV. Its origin is unknown. This thesis investigates the nature of cosmic rays with energy near 10 18.5 eV, and it evaluates two phenomenological models for the ankle feature. Data from the Pierre Auger Observatory is used. Two important calibration studies for the Pierre Auger Observatory are presented: (1) A measurement of the time offset between the surface detector and the fluorescence detector, and (2) A measurement of the fluorescence telescope alignment. The uncertainty on the time offset measurement is 20 ns and the uncertainty on the fluorescence telescope alignment is 0.14°; both uncertainties are within the design specifications of the observatory. Studies to determine the cosmic ray composition mixture near the ankle are presented. Measurements of the average depth of shower maximum suggest that the average particle mass is gradually decreasing between 10 17.8 and 10 18.4 eV and that the average particle mass is steady or slightly increasing between 10 18.5 and 10 19.0 eV. Measurements of the average depth of shower maximum also suggest that the fractional abundance of intermediate weight nuclei such as carbon steadily increases from 10 18 to 10 19 eV. Between 10 18.5 and 10 19.0 eV, the correlation between the depth of shower maximum and the ground level muon density is consistent with a significant fractional abundance of both protons and intermediate weight nuclei. Two popular phenomenological models for the ankle are compared with the above composition results. The first model is that the ankle marks the intersection between a soft galactic spectrum and a hard extragalactic spectrum. The second model is that the ankle is part of a dip in the cosmic ray spectrum (the pair production dip) caused by the attenuation of protons as they travel through intergalactic space. It is demonstrated that the experimental results favor the first model.

Aime, C.; Soummer, R.

very short explanation of how the reports are ordered is given here. The Journées of 2003 started with the delocalized lectures (delocalized means here “not in Paris”!) of the Collège de France, of Antoine Labeyrie who wrote a report on Removal of coronagraphy residues with an adaptive hologram. Three invited seminars follow: Olivier Guyon (Pupil remapping techniques), Daniel Rouan (Ultra-nulling interferometers), and Kjetil Dohlen (Phase masks in astronomy). An illustration from Daniel Rouan's talk on the properties of Prouhet-Thué-Morse series was also selected for the cover figure of this edition. These papers are followed by the courses and communications given during the 4 days of the school, in a slightly different order of their presentation. The first two days were on atmospheric turbulence and adaptive optics for coronagraphy, and also coronagraphic space projects. Steve Ridgway gives a general introduction to the problem (Astronomy with high contrast imaging). This is followed by a presentation on Fourier and Statistical Optics: Shaped and Apodized apertures (Claude Aime), The effect of a coronagraph on the statistics of adaptive optics pinned speckles (Claude Aime and Rémi Soummer). A general introduction to the problem of atmospheric turbulence is made by Julien Borgnino. A presentation of the Concordia site with emphasis on its advantages for high contrast imaging is given by Eric Fossat. Several presentations relative to numerical simulations of Adaptive Optics and coronagraphy follow: Marcel Carbillet (AO for very high contrast imaging), Lyu Abe and Anthony Boccaletti share two presentations on Numerical simulations for coronagraphy. These presentations are followed by reports on experiments: Sandrine Thomas (SAM-the SOAR adaptive module), Pierre Baudoz (Cryogenic IR test of the 4QPM coronagraph), Anthony Boccaletti (Coronagraphy with JWST in the thermal IR). Pierre Bourget (Hg-Mask Coronagraph) ends this part with a coronagraph using a mercury

Cosmological implications of a stellar initial mass function that varies with the Jeans mass in galaxies

Narayanan, Desika; Davé, Romeel

2012-07-01

Observations of star-forming galaxies at high z have suggested discrepancies in the inferred star formation rates (SFRs) either between data and models or between complementary measures of the SFR. These putative discrepancies could all be alleviated if the stellar initial mass function (IMF) is systematically weighted towards more high-mass star formation in rapidly star-forming galaxies. Here, we explore how the IMF might vary under the central assumption that the turnover mass in the IMF, ?, scales with the Jeans mass in giant molecular clouds (GMCs), ?. We employ hydrodynamic simulations of galaxies coupled with radiative transfer models to predict how the typical GMC Jeans mass, and hence the IMF, varies with galaxy properties. We then study the impact of such an IMF on the star formation law, the SFR-M* relation, sub-millimetre galaxies (SMGs) and the cosmic SFR density. Our main results are: the H2 mass-weighted Jeans mass in a galaxy scales well with the SFR when the SFR is greater than a few M⊙ yr-1. Stellar population synthesis modelling shows that this results in a non-linear relation between SFR and Lbol, such that SFR ?. Using this model relation, the inferred SFR of local ultraluminous infrared galaxies decreases by a factor of ˜2, and that of high-z SMGs decreases by a factor of ˜3-5. At z˜ 2, this results in a lowered normalization of the SFR-M* relation in better agreement with models, a reduced discrepancy between the observed cosmic SFR density and stellar mass density evolution, and SMG SFRs that are easier to accommodate in current hierarchical structure formation models. It further results in a Kennicutt-Schmidt star formation law with a slope of ˜1.6 when utilizing a physically motivated form for the CO-H2 conversion factor that varies with galaxy physical property. While each of the discrepancies considered here could be alleviated without appealing to a varying IMF, the modest variation implied by assuming ? is a plausible solution

CONSTRAINTS ON THE SHAPE OF THE MILKY WAY DARK MATTER HALO FROM JEANS EQUATIONS APPLIED TO SLOAN DIGITAL SKY SURVEY DATA

We search for evidence of dark matter in the Milky Way by utilizing the stellar number density distribution and kinematics measured by the Sloan Digital Sky Survey (SDSS) to heliocentric distances exceeding {approx}10 kpc. We employ the cylindrically symmetric form of Jeans equations and focus on the morphology of the resulting acceleration maps, rather than the normalization of the total mass as done in previous, mostly local, studies. Jeans equations are first applied to a mock catalog based on a cosmologically derived N-body+SPH simulation, and the known acceleration (gradient of gravitational potential) is successfully recovered. The same simulation is alsomore » used to quantify the impact of dark matter on the total acceleration. We use Galfast, a code designed to quantitatively reproduce SDSS measurements and selection effects, to generate a synthetic stellar catalog. We apply Jeans equations to this catalog and produce two-dimensional maps of stellar acceleration. These maps reveal that in a Newtonian framework, the implied gravitational potential cannot be explained by visible matter alone. The acceleration experienced by stars at galactocentric distances of {approx}20 kpc is three times larger than what can be explained by purely visible matter. The application of an analytic method for estimating the dark matter halo axis ratio to SDSS data implies an oblate halo with q{sub DM} = 0.47 {+-} 0.14 within the same distance range. These techniques can be used to map the dark matter halo to much larger distances from the Galactic center using upcoming deep optical surveys, such as LSST.« less

Ultrahigh energy cosmic ray air showers probe particle physics at energies beyond the reach of accelerators. Here we introduce a new method to test hadronic interaction models without relying on the absolute energy calibration, and apply it to events with primary energy 6-16 EeV (ECM=110 - 170 TeV ), whose longitudinal development and lateral distribution were simultaneously measured by the Pierre Auger Observatory. The average hadronic shower is 1.33 ±0.16 (1.61 ±0.21 ) times larger than predicted using the leading LHC-tuned models EPOS-LHC (QGSJetII-04), with a corresponding excess of muons.

A knowledge of past overburden thickness is useful for designing underground structures such as waste repositories. This study attempts to determine if a correlation can be made between a geologic estimate and two types of geotechnical calculations of past overburden thickness. In the Pierre-Hayes area, Late Cretaceous Pierre Shales is the only bedrock present, but clasts of the Miocene Ogallala Formation were found in the Pleistocene deposits, suggesting that rocks of the Ogallala Formation once covered this area. Based on the geologic estimate, the Ogallala surface was 1100 ft higher than the present surface. Of the two types of geotechnical data acquired for the Hayes site, the laboratory overconsolidation ratios indicate a past overburden thickness value of 2300 ft, whereas the in situ pressuremeter overconsolidation ratios indicate 1318 ft. We, therefore, believe that in situ determination is a better indicator of past overburden that the laboratory results. However, why the two test results differ to this degree is unknown at present.-from Authors

The Jeans instability of self-gravitating optically thick quantum plasma is reanalyzed in the framework of viscosity, black body radiation and modify ohms law. The usual magnetohydrodynamic (MHD) equation is used for the present configuration with black body radiation, viscosity, electrical resistivity and quantum corrections. A general dispersion relation is obtained with the help of linearized perturbation equations. It is found that the quantum correction has stabilizing effect on the system. The instability of system is discussed for various cases as our interest.

The mass composition of ultra-high energy cosmic rays with the Pierre Auger Observatory

NASA Astrophysics Data System (ADS)

Martraire, D.

2014-12-01

Ultra-high energy cosmic rays are the most energetic particles known in nature. The Pierre Auger Observatory was built to study these amazing particles to determine their origin. The study of their mass composition can help to constrain the models concerning their origins and their production mechanisms in the astrophysical sources. To this aim, several methods have been developed to infer the composition using the Auger surface detector array data. The main difficulty is to isolate the muonic component in the signal measured by the surface detector. We present the results of the composition parameters derived from the ground level component and compare them to the predictions for different nuclear masses of the primary particles and hadronic interaction models.

Human rights assessment in Parc Jean Marie Vincent, Port-au-Prince, Haiti.

Cullen, Kimberly A; Ivers, Louise C

2010-12-15

Months after a 7.0 magnitude earthquake hit Port-au-Prince, Haiti, over one million remain homeless and living in spontaneous internally displaced person (IDP) camps. Billions of dollars from aid organizations and government agencies have been pledged toward the relief effort, yet many basic human needs, including food, shelter, and sanitation, continue to be unmet. The Sphere Project, "Humanitarian Charter and Minimum Standards in Disaster Response," identifies the minimum standards to be attained in disaster response. From a human rights perspective and utilizing key indicators from the Sphere Project as benchmarks, this article reports on an assessment of the living conditions approximately 12 weeks after the earthquake in Parc Jean Marie Vincent, a spontaneous IDP camp in Port-au-Prince. A stratified random sample of households in the camp, proportionate to the number of families living in each sector, was selected. Interview questions were designed to serve as "key indicators" for the Sphere Project minimum standards. A total of 486 interviews were completed, representing approximately 5% of households in each of the five sectors of the camp. Our assessment identified the relative achievements and shortcomings in the provision of relief services in Parc Jean Marie Vincent. At the time of this survey, the Sphere Project minimum standards for access to health care and quantity of water per person per day were being met. Food, shelter, sanitation, and security were below minimum accepted standard and of major concern. The formal assessment reported here was completed by September 2010, and is necessarily limited to conditions in Haiti before the cholera outbreak in October. Copyright © 2010 Cullen and Ivers.

Ultrahigh energy cosmic ray air showers probe particle physics at energies beyond the reach of accelerators. Here we introduce a new method to test hadronic interaction models without relying on the absolute energy calibration, and apply it to events with primary energy 6-16 EeV (E_{CM}=110-170  TeV), whose longitudinal development and lateral distribution were simultaneously measured by the Pierre Auger Observatory. The average hadronic shower is 1.33±0.16 (1.61±0.21) times larger than predicted using the leading LHC-tuned models EPOS-LHC (QGSJetII-04), with a corresponding excess of muons.

Ultrahigh energy cosmic ray air showers probe particle physics at energies beyond the reach of accelerators. Here we introduce a new method to test hadronic interaction models without relying on the absolute energy calibration, and apply it to events with primary energy 6–16 EeV (E CM = 110–170 TeV), whose longitudinal development and lateral distribution were simultaneously measured by the Pierre Auger Observatory. As a result, the average hadronic shower is 1.33±0.16 (1.61±0.21) times larger than predicted using the leading LHC-tuned models EPOS-LHC (QGSJetII-04), with a corresponding excess of muons.

Atmospheric conditions at the site of a cosmic ray observatory must be known for reconstructing observed extensive air showers. The Global Data Assimilation System (GDAS) is a global atmospheric model predicated on meteorological measurements and numerical weather predictions. GDAS provides altitude-dependent profiles of the main state variables of the atmosphere like temperature, pressure, and humidity. The original data and their application to the air shower reconstruction of the Pierre Auger Observatory are described. By comparisons with radiosonde and weather station measurements obtained on-site in Malargüe and averaged monthly models, the utility of the GDAS data is shown.

Thirteen days: Joseph Delboeuf versus Pierre Janet on the nature of hypnotic suggestion.

PubMed

LeBlanc, André

2004-01-01

The problem of post-hypnotic suggestion was introduced in 1884. Give a hypnotic subject the post-hypnotic command to return in 13 days. Awake, the subject remembers nothing yet nonetheless fulfills the command to return. How then does the subject count 13 days without knowing it? In 1886, Pierre Janet proposed the concept of dissociation as a solution, arguing that a second consciousness kept track of time outside of the subject's main consciousness. Joseph Delboeuf, in 1885, and Hippolyte Bernheim, in 1886, proposed an alternative solution, arguing that subjects occasionally drifted into a hypnotic state in which they were reminded of the suggestion. This article traces the development of these competing solutions and describes some of Delboeuf's final reflections on the problem of simulation and the nature of hypnosis.

This study investigates the cultural and educational ideas of the French deaf poet-teacher Pierre Pelissier (1814-1863) who was an instructor at the Paris Deaf Institute from the early 1840s until his death in 1863. As a young man, Pelissier became interested in composing poetry and through his verse, captured many of the social frustrations…

"I would eagerly leave Neuchâtel ..." A 1912 letter by Jean Piaget with an introduction and notes.

Vidal, F

1986-01-01

A 1912 letter from fifteen-year-old Jean Piaget (1896-1980) to the director of the Museum of Natural History of Geneva illustrates Piaget's precocious integration into a community of professional naturalists, and reveals his hitherto unknown plan to study medicine. It is not certain whether he actually intended to realize that plan. An essential biographical fact, however, is that he finally left natural history by turning to philosophy rather than to medicine.

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

We present a combined fit of a simple astrophysical model of UHECR sources to both the energy spectrum and mass composition data measured by the Pierre Auger Observatory. The fit has been performed for energies above 5 ṡ 1018 eV, i.e. the region of the all-particle spectrum above the so-called "ankle" feature. The astrophysical model we adopted consists of identical sources uniformly distributed in a comoving volume, where nuclei are accelerated through a rigidity-dependent mechanism. The fit results suggest sources characterized by relatively low maximum injection energies, hard spectra and heavy chemical composition. We also show that uncertainties about physical quantities relevant to UHECR propagation and shower development have a non-negligible impact on the fit results.

To search for studies on tongue-lip adhesion and tongue repositioning used as isolated treatments for obstructive sleep apnoea in children with Pierre Robin sequence. A systematic literature search of PubMed/Medline and three additional databases, from inception through to 8 July 2016, was performed by two authors. Seven studies with 90 patients (59 tongue-lip adhesion and 31 tongue repositioning patients) met the inclusion criteria. Tongue-lip adhesion reduced the mean (± standard deviation) apnoea/hypopnoea index from 30.8 ± 22.3 to 15.4 ± 18.9 events per hour (50 per cent reduction). The apnoea/hypopnoea index mean difference for tongue-lip adhesion was -15.28 events per hour (95 per cent confidence interval = -30.70 to 0.15; p = 0.05). Tongue-lip adhesion improved the lowest oxygen saturation from 75.8 ± 6.8 to 84.4 ± 7.3 per cent. Tongue repositioning reduced the apnoea/hypopnoea index from 46.5 to 17.4 events per hour (62.6 per cent reduction). Tongue repositioning improved the mean oxygen saturation from 90.8 ± 1.2 to 95.0 ± 0.5 per cent. Tongue-lip adhesion and tongue repositioning can improve apnoea/hypopnoea index and oxygenation parameters in children with Pierre Robin sequence and obstructive sleep apnoea.

In 1929, psychologist Lois Meek praised Piaget's research in the National Society for the Study of Education's…

Antoine-Marie Chambeyron (1797-1851): a forgotten disciple of Jean-Etienne Esquirol (1772-1840).

Antoine-Marie Chambeyron (1797-1851) was a disciple of Jean-Etienne Esquirol (1772-1840) that history forgot, undoubtedly because he made no original contribution to psychiatric nosography. In 1827, his interest in the medical-legal status of the insane led him to translate into French and annotate the first medical-legal psychiatric treatise ever published, which was the work of the German philosopher Johann Christoph Hoffbauer (1766-1827). His translation played a role in shaping the French Law of 1838, the first piece of modern legislation aimed at protecting the rights of mental patients and limiting the State's power to confine them arbitrarily. Chambeyron is among the least-cited contributors to the prestigious work of nineteenth-century French alienists.

Pierre-François Nicolas, was born in Saint-Mihiel in 1743, studied in this town and in St-Nicolas-de-Port near Nancy. At first he has been a military apothecary during the "Guerre de Sept-Ans". Then he studied pharmacy in Nancy and was received in 1768 at the "Maîtrise de pharmacie". With the physician Henri Michel du Tennatar, he created a teaching of chemistry for medicine students and became the professor of chemistry of the Faculty of Medicine in 1781. During these years, he published some research results about hydrology, distillery, biochemistry (phosphorus in bone), toxicology, dyeing... At the end of 1783, he succeeded in the realization of a balloon and he played an important part in Nancy during the French Revolution. Professor at the "Ecole de médecine" in Strasbourg for some weeks, then in Nancy at the "Ecole centrale" and at the "Société de santé", he left Nancy towards the mid-1798. Staying in Paris for two or three years he probably worked with Fourcroy and perhaps Chaptal and Berthollet. In the early years of the nineteenth century he was appointed professor in the "Ecole centrale" du Calvados" and some years after at the "Faculté des sciences" in Caen. His latest significant work with Gueudeville was devoted to the detection of sugar in the urine of diabetic patients. Retired in 1811 Pierre-François Nicolas died in Caen in 1816.

We present a novel method to measure precisely the relative spectral response of the fluorescence telescopes of the Pierre Auger Observatory. We used a portable light source based on a xenon flasher and a monochromator to measure the relative spectral efficiencies of eight telescopes in steps of 5 nm from 280 nm to 440 nm. Each point in a scan had approximately 2 nm FWHM out of the monochromator. Different sets of telescopes in the observatory have different optical components, and the eight telescopes measured represent two each of the four combinations of components represented in the observatory. We made an end-to-end measurement of the response from different combinations of optical components, and the monochromator setup allowed for more precise and complete measurements than our previous multi-wavelength calibrations. We find an overall uncertainty in the calibration of the spectral response of most of the telescopes of 1.5% for all wavelengths; the six oldest telescopes have larger overall uncertainties of about 2.2%. We also report changes in physics measurables due to the change in calibration, which are generally small.

Search for Ultra-relativistic Magnetic Monopoles with the Pierre Auger Observatory

DOE PAGES

Aab, Alexander

2016-10-03

In this paper, we present a search for ultra-relativistic magnetic monopoles with the Pierre Auger Observatory. Such particles, possibly a relic of phase transitions in the early universe, would deposit a large amount of energy along their path through the atmosphere, comparable to that of ultrahigh-energy cosmic rays (UHECRs). The air shower profile of a magnetic monopole can be effectively distinguished by the fluorescence detector from that of standard UHECRs. No candidate was found in the data collected between 2004 and 2012, with an expected background of less than 0.1 event from UHECRs. The corresponding 90% confidence level (C.L.) upper limits on the flux of ultra-relativistic magnetic monopoles range frommore » $$10^{-19}$$ (cm$$^{2}$$ sr s)$$^{-1}$$ for a Lorentz factor $$\\gamma=10^9$$ to $$2.5 \\times10^{-21}$$ (cm$$^{2}$$ sr s)$$^{-1}$$ for $$\\gamma=10^{12}$$. Lastly, these results - the first obtained with a UHECR detector - improve previously published limits by up to an order of magnitude.« less

Riggs, S R; Bright, M A

1997-08-01

Women diagnosed with Dissociative Identity Disorder (DID) may experience episodic crises characterized by intense states of disconnection from self and others. Crises which result in potential harm to self/others may require inpatient treatment. With economic emphasis on shorter lengths of stay, a treatment program or model which focuses on the DID patient's sense of connectedness to self and others can enhance treatment efforts during brief inpatient hospitalizations. The Relational Model of Jean Baker Miller uses mutuality and empowerment within the therapeutic relationship and inpatient mileu to move the patient beyond therapeutic impasse/crisis toward a state of greater connectedness to self and others.

Aerosol concentration measurements and correlations with air mass trajectories at the Pierre Auger Observatory

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

The fit has been performed for energies above 5 ⋅ 10{sup 18} eV, i.e. the region of the all-particle spectrum above the so-called 'ankle' feature. The astrophysical model we adopted consists of identical sources uniformly distributed in a comoving volume, where nuclei are accelerated through a rigidity-dependent mechanism. The fit results suggest sources characterized by relatively low maximum injection energies, hard spectra and heavy chemical composition.

Measuring the speed resolution of extensive air showers at the Southern Pierre Auger Observatory

NASA Astrophysics Data System (ADS)

Gesterling, Kathleen; Sarazin, Fred

2009-10-01

Ultra-high energy cosmic rays induce extensive air showers (EASs) in Earth's atmosphere which are assumed to propagate at the speed of light. The fluorescence detector (FD) at the Southern Pierre Auger Observatory detects the light signal from the EAS and directly measures the energy of the cosmic ray. When two or more FD sites observe an event, the geometry of the shower can be calculated independently of the velocity it is traveling. It is then possible to fit the time profile recorded in the FD using the shower speed as a free parameter. The analysis of a collection of stereo events allowed us to determine with what speed resolution we can measure EASs with sensitivity to subluminal components. Knowing the speed resolution we can look for objects propagating significantly below the speed of light.

Toby’s relationship with Paris Observatory goes back to the early beginning of the 1970s. While he was a professor at Sony Brook University (NY), he played a very active role in the development of the young planetology group at the Observatory. With Daniel Gautier, Catherine de Bergh, Michel Combes and Thérèse Encrenaz, he initiated many research projects around the composition and structure of planetary atmospheres, using space exploration and ground-based observations. With Jean-Pierre Maillard and the French planetology group, he made a series of major discoveries, in particular about the deuterium abundance in the solar system. In a visionary and multidisciplinary approach, he developed numerous research projects on all families of solar system objects, planets, satellites and comets, using all wavelength spectral ranges, from ground and space. In the early 1980s, with Daniel Gautier and Wing Ip, Toby became deeply involved in the development of the Cassini-Huygens space mission, jointly led by the United States and Europe, devoted to the exploration of Saturn and Titan. Beyond its exceptional scientific return, this mission has been an exemplary success in terms of international cooperation between different space agencies. Toby was strongly in favor of bringing together scientific communities beyond national frontiers. With his French friends and colleagues, at Paris Observatory and beyond, Toby has developed very strong links of scientific cooperation and friendship. In the early 2000s, he joined the High Scientific Council of Paris Observatory. In 2006, with Daniel Gautier and Jean-Pierre Lebreton, he received the Grand Prix Marcel Dassault of the French Academy of Sciences. In 2007, he became Doctor Honoris Causa of Paris Observatory. He is deeply missed by his friends and colleagues, who all remember his generosity, his availability, his kindness, his simplicity and modesty.

The Cherenkov Surface Detector of the Pierre Auger Observatory

NASA Astrophysics Data System (ADS)

Billoir, Pierre

2014-12-01

The Pierre Auger Observatory detects the atmospheric showers induced by cosmic rays of ultra-high energy (UHE). It is the first one to use the hybrid technique. A set of telescopes observes the fluorescence of the nitrogen molecules on clear moonless nights, giving access to the longitudinal profile of the shower. These telescopes surround a giant array of 1600 water Cherenkov tanks (covering more than 3000 km2), which works continuously and samples the particles reaching the ground (mainly muons, photons and electrons/positrons); the light produced within the water is recorded into FADC (Fast Analog to Digital Convertes) traces. A subsample of hybrid events provides a cross calibration of the two components. We describe the structure of the Cherenkov detectors, their sensitivity to different particles and the information they can give on the direction of origin, the energy and the nature of the primary UHE object; we discuss also their discrimination power for rare events (UHE photons or neutrinos). To cope with the variability of weather conditions and the limitations of the communication system, the procedures for trigger and real time calibration have been shared between local processors and a central acquisition system. The overall system has been working almost continuously for 10 years, while being progressively completed and increased by the creation of a dense "infill" subarray.

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

Simultaneous measurements of air showers with the fluorescence and surface detectors of the Pierre Auger Observatory allow a sensitive search for EeV photon point sources. Several Galactic and extragalactic candidate objects are grouped in classes to reduce the statistical penalty of many trials from that of a blind search and are analyzed for a significant excess above the background expectation. The presented search does not find any evidence for photon emission at candidate sources, and combined p-values for every class are reported. Particle and energy flux upper limits are given for selected candidate sources. These limits significantly constrain predictions of EeV proton emission models from non-transient Galactic and nearby extragalactic sources, as illustrated for the particular case of the Galactic center region.

Even if the attempt was a failure, it remains that the proposals were part of Frank in both an ancient tradition that priests and physicians providing care for souls and bodies, but also showed that called his wishes the advent of "public health" in this country disinherited.

Cloud cameras at the Pierre Auger Observatory

NASA Astrophysics Data System (ADS)

Winnick, Michael G.

2010-06-01

This thesis presents the results of measurements made by infrared cloud cameras installed at the Pierre Auger Observatory in Argentina. These cameras were used to record cloud conditions during operation of the observatory's fluorescence detectors. As cloud may affect the measurement of fluorescence from cosmic ray extensive air showers, the cloud cameras provide a record of which measurements have been interfered with by cloud. Several image processing algorithms were developed, along with a methodology for the detection of cloud within infrared images taken by the cloud cameras. A graphical user interface (GUI) was developed to expediate this, as a large number of images need to be checked for cloud. A cross-check between images recorded by three of the observatory's cloud cameras is presented, along with a comparison with independent cloud measurements made by LIDAR. Despite the cloud cameras and LIDAR observing different areas of the sky, a good agreement is observed in the measured cloud fraction between the two instruments, particularly on very clear and overcast nights. Cloud information recorded by the cloud cameras, with cloud height information measured by the LIDAR, was used to identify those extensive air showers that were obscured by cloud. These events were used to study the effectiveness of standard quality cuts at removing cloud afflicted events. Of all of the standard quality cuts studied in this thesis, the LIDAR cloud fraction cut was the most effective at preferentially removing cloud obscured events. A 'cloudy pixel' veto is also presented, whereby cloud obscured measurements are excluded during the standard hybrid analysis, and new extensive air shower reconstructed parameters determined. The application of such a veto would provide a slight increase to the number of events available for higher level analysis.

We present the results of searches for dipolar-type anisotropies in different energy ranges above 2.5 × 1017 eV with the surface detector array of the Pierre Auger Observatory, reporting on both the phase and the amplitude measurements of the first harmonic modulation in the right-ascension distribution. Upper limits on the amplitudes are obtained, which provide the most stringent bounds at present, being below 2% at 99% C.L. for EeV energies. We also compare our results to those of previous experiments as well as with some theoretical expectations.

This report describes the presentation of a newborn male with circumferential tongue-palate fusion associated with cleft palate and alveolar bands. After intraoral adhesions lysis, the patient was diagnosed with Pierre Robin sequence. A family history of cleft lip and palate was noted, and interferon regulatory factor 6 ( IRF6) sequencing revealed a heterozygous variant, confirming the diagnosis of van der Woude syndrome. The disruption of IRF6 resulted in abnormal orofacial development including micrognathia and intraoral adhesions as well as tongue-palate fusion, then resulting in glossoptosis with airway obstruction and cleft palate.

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

Sparking controversy: Jean Antoine Nollet and medical electricity south of the Alps.

PubMed

Bertucci, Paola

2005-01-01

The paper considers a significant episode in the history of eighteenth-century electricity: the controversy over the "medicated tubes". Invented by the Italian erudite Gianfrancesco Pivati, the tubes were said to produce instantaneous cures. Jean Antoine Nollet was one of the main actors of the controversy. In 1749, after touring Italy to see for himself the Italian tubes and their effects, he published a report, discrediting Pivati's accounts. This study shows that the report, which has since been the main source for interpretations of the controversy, hides the key role of the Bologna Istituto delle Scienze in promoting Pivati's invention. Relying on manuscript sources, I propose a change of perspective on the controversy that illuminates the world of Italian experimental philosophy during the Enlightenment and its place in the Republic of Letters. I also analyze the reasons for Nollet's silence over the involvement of the Istituto delle Scienze in the controversy and the relevance of medical electricity in the wider context of contemporary electrical experimental philosophy.

Dull Brains and Frozen Feet: A Historical Essay on Cold.

Lankford, Harvey V

2016-12-01

This essay will review historical and medical aspects of cold exposure, hypothermia, and frostbite during the Napoleonic era. The 19th century writings of Dominique Jean Larrey, Pierre Jean Moricheau-Beaupré, and others are used to provide an evocative supporting narrative to illustrate some of the cold illnesses, physiology, and theory of both an earlier era and the present time. Medical care for over a century followed the how but not the why of treating frostbite and hypothermia slowly with snow or cold water rather than heat. There were 2 main reasons: First was a practical attempt to limit gangrene. Less known, and long forgotten, is a major rationale based on the erroneous theory of heat called "the caloric." Because of these 2 reasons, the slow method of "cold warming" remained standard medical practice well into the 20th century. Although these recommendations are now known to be flawed, some of the reasons behind them will be discussed, along with early but correct observations on afterdrop and circumrescue collapse. There is a long backstory of treatment from 1812 to the present. Copyright © 2016 Wilderness Medical Society. Published by Elsevier Inc. All rights reserved.

New electronics for the surface detectors of the Pierre Auger Observatory

NASA Astrophysics Data System (ADS)

Kleifges, M.; Pierre Auger Collaboration

2016-07-01

The Pierre Auger Observatory is the largest installation worldwide for the investigation of ultra-high energy cosmic rays. Air showers are detected using a hybrid technique with 27 fluorescence telescopes and 1660 water-Cherenkov detectors (WCD) distributed over about 3000 km2. The Auger Collaboration has decided to upgrade the electronics of the WCD and complement the surface detector with scintillators (SSD). The objective is to improve the separation between the muonic and the electron/photon shower component for better mass composition determination during an extended operation period of 8-10 years. The surface detector electronics records data locally and generates time stamps based on the GPS timing. The performance of the detectors is significantly improved with a higher sampling rate, an increased dynamic range, new generation of GPS receivers, and FPGA integrated CPU power. The number of analog channels will be increased to integrate the new SSD, but the power consumption needs to stay below 10 W to be able to use the existing photovoltaic system. In this paper, the concept of the additional SSD is presented with a focus on the design and performance of the new surface detector electronics.

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

PubMed

Schinkel, Willem

2015-06-01

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

Spectral calibration of the fluorescence telescopes of the Pierre Auger Observatory

Aab, A.; Abreu, P.; Aglietta, M.

We present a novel method to measure precisely the relative spectral response of the fluorescence telescopes of the Pierre Auger Observatory. Here, we used a portable light source based on a xenon flasher and a monochromator to measure the relative spectral efficiencies of eight telescopes in steps of 5 nm from 280 nm to 440 nm. Each point in a scan had approximately 2 nm FWHM out of the monochromator. Different sets of telescopes in the observatory have different optical components, and the eight telescopes measured represent two each of the four combinations of components represented in the observatory. Wemore » made an end-to-end measurement of the response from different combinations of optical components, and the monochromator setup allowed for more precise and complete measurements than our previous multi-wavelength calibrations. We find an overall uncertainty in the calibration of the spectral response of most of the telescopes of 1.5% for all wavelengths; the six oldest telescopes have larger overall uncertainties of about 2.2%. We also report changes in physics measureables due to the change in calibration, which are generally small.« less

[Baron Dominique-Jean Larrey: the founder of urological traumatology].

Hatzinger, M; Ameijenda, C; Lent, V; Sohn, M

Dominique-Jean Larrey (1766-1842) was Surgeon-in-Chief of the Grande Army under Napoleon Bonaparte (1769-1821) and personal physician of the Emperor. Against the opposition of the traditionalists he introduced the "ambulances volantes", the so-called flying ambulances. The aim was the medical treatment of the injured soldiers immediately on the battlefield. This revolutionary treatment led to a benefit not only for the own soldiers, but also for the wounded enemies. His innovation in the field of immediate assistance of wounded persons, together with Larreys' outstanding medical competence, saved thousands of soldiers lives on the battlefield of the Napoleonic wars. His memories concerning the military campaigns, have been even up to the 20th century one of the standard works of modern military surgery. He had as well great interest in urolological injuries of the urinary system and their conservative and operative care. Up to these days, his work shows a surprising actuality and perfect anatomic understanding. In a time without anaesthetics, antibiotics and under primitive circumstances, Larrey and his collegues accomplished surgical feats. Larreys flying ambulances were copied by many different countries. The American Mobile Army Surgical Hospital (M.A.S.H) is clearly based on his thoughts and ideals. In our opinion he is the father of the modern war surgery as well the urological traumatology.

Jean-Jacques Rousseau sold his botanical texts to Daniel Malthus (father of Thomas Malthus) about 1775. Two of these are now in the Old Library, Jesus College, Cambridge, but all the rest have long been thought lost. However, a copy of Albrecht von Haller's Historia stirpium indigenarum Helvetiae inchoata (1768) in the Lindley Library, Royal Horticultural Society, London, bears Rousseau's name and seems to have been annotated by him. The volume contains the bookplate of Jane Dalton, a cousin to whom Malthus willed "all[his] Botanical Books in which the name of Rousseau is written". Haller was well-known to Rousseau, who while in exile in the Swiss Jura (1763-1765), studied under one of Haller's collaborators, Abraham Gagnebin. Rousseau cited Haller's entry 762 when describing a species of Seseli to the Duchess of Portland.

A Targeted Search for Point Sources of EeV Photons with the Pierre Auger Observatory

Simultaneous measurements of air showers with the fluorescence and surface detectors of the Pierre Auger Observatory allow a sensitive search for EeV photon point sources. Several Galactic and extragalactic candidate objects are grouped in classes to reduce the statistical penalty of many trials from that of a blind search and are analyzed for a significant excess above the background expectation. The presented search does not find any evidence for photon emission at candidate sources, and combined p-values for every class are reported.

SRTM Anaglyph with Landsat Overlay: Miquelon and Saint Pierre Islands

NASA Technical Reports Server (NTRS)

2000-01-01

This anaglyph satellite image shows Miquelon and Saint Pierre Islands, located south of Newfoundland, Canada. These islands are a self-governing territory of France. A 'tombolo' (sand bar) unites Grande Miquelon to the north and Petite Miquelon to the south. Saint Pierre Island, located to the lower right, includes a harbor, an airport, and a small town. Glaciers once covered these islands and the direction of glacial flow is evident in the topography as striations and shoreline trends running from the upper right to the lower left. The darkest image features are freshwater lakes that fill glacially carved depressions and saltwater lagoons that are bordered by barrier beaches. The lakes and the lagoons are fairly calm waters and reflect less sunlight than do the wave covered and sediment laden nearshore ocean currents.

The stereoscopic effect was created by first draping a Landsat satellite image over preliminary digital elevation data from the Shuttle Radar Topography Mission (SRTM), and then generating two differing perspectives, one for each eye. When viewed through special glasses, the result is a vertically exaggerated view of the Earth's surface in its full three dimensions. Anaglyph glasses cover the left eye with a red filter and cover the right eye with a blue filter.

Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter resolution of most Landsat images and will substantially help in analyses of the large and growing Landsat image archive. The Landsat 7 Thematic Mapper image used here was provided to the SRTM project by the United States Geological Survey, Earth Resources Observation Systems (EROS) DataCenter, Sioux Falls, South Dakota.

The elevation data used in this image was acquired by SRTM aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR

LA SAFE and Isle de Jean Charles: Regional Adaptation and Community Resettlement Planning

Sanders, M.

2017-12-01

LA SAFE, or Louisiana's Strategic Adaptations for Future Environments, is a strategic framework for community development utilizing future projections of coastal land loss and flood risk as a determining factor in regional growth management and local planning initiatives along a 10, 25, and 50 year timeline. LA SAFE utilizes the input of passionate local citizen leaders and organizations committed to enabling community members to take proactive steps towards mitigating risk and increasing resilience against coastal issues. The project aims to acknowledge that adaptation and restoration must go hand-in-hand with addressing community growth and contraction, as well as realizing Louisiana's most vulnerable coastal communities will need to contemplate resettlement over the next 50 years. The project's outlook is to become a global leader for adaptation and cultural design and restoration. Connecting a global interest with the project and offering extensive ways for people to learn about the issues and get involved will provide an immense amount of support necessary for future coastal environments around the world. This presentation will focus on the output of a year-long planning effort across a six-parish target area encompassing several vulnerable coastal Louisiana locales. The Resettlement of Isle de Jean Charles is a federally-funded and first-of-its kind initiative marking Louisiana's first attempt to relocate a vulnerable coastal community at-scale and as a group. Due to a myriad of environmental factors, the Island has experienced 98 percent land loss since 1955, leading to many of the Island's historical inhabitants to retreat to higher, drier landscapes. In moving the community at-scale, the project seeks to inject new life into the community and its residents in relocating the community to higher, safer ground, while also developing the new community in such a way that it maximizes economic development, job training, and educational opportunities and can be a

2011-01-01

Pierre Janet's works on conversion disorders or dissociative disorders has mainly fallen to the wayside in favour of Freud's works. In the first part of this paper, Janet's conception of hysteria is discussed and his place in French psychiatry described. Different aspects of Janet's diathesis-stress approach are presented (particularly the pathogenic concept of fixed ideas), which refer not only to a conception of hysteria but also to traumatic (stress) disorders and other psychological disturbances. The second part of the paper details the varieties of Janetian therapeutic treatments of these disorders: the "liquidation" of fixed ideas by hypnosis and suggestion, confrontation techniques, which resemble contemporary cognitive behavioural approaches, and special cognitive ("logagogic") interventions. Finally, we discuss the various treatment strategies based on psychoeconomic considerations such as physical or psycho-phyical therapies, psychoeducation, treatment through rest, and simplification of life for dealing with basic disturbances of psychic disorders.

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

In this work we present the participations of the Mexican group at development of the Pierre Auger Observatory. We have been working in both parts of the hybrid proposed for the Auger detector, the fluorescence and the surface detectors. In the part of fluorescence, we have analyzed the resolution of the Hi-Res optical design of the fluorescence detector observatory. We have found a heterogeneus image resolution. We propose to use a lensless Schmidt camera (with spherical image surface) to duplicate the field of view to 30×30 degrees and simultaneously guarantee a resolution of one degree over of the whole field of view. By the Surface Detector, a water Čerenkov detector (WCD) prototype of reduced dimensions (cylinder 1.54 diameter filled with purified water up to 1.20 m high) is used to obtain preliminary experimental results that validate the concept of remote calibration and monitoring of WCDs. We use muons that stop and decay inside the WCD and, in a complementary way, muons that croos the WCD. We used a moun telescope trigger in order to study the charge distribution of vertical muons, their pulse amplitude decay and the Cerenkov light attenuation length of those secondary cosmic muons we include the bacteria population content for the four months of operation to validate the monitoring method.

Specialists of the history of hysteria know the name of Jean-Louis Brachet (1789-1858), but few realise the influence of this physician and surgeon from Lyon, a city in the southeastern part of France. Not only a clinician, he was also a neurophysiology researcher in the early 19th century. Along with his descriptions of meningoencephalitis, including hydrocephalus and meningoencephalitis, he elucidated the functioning of the vegetative nervous system and described its activity during emotional states. He also helped describe the different forms of epilepsy and sought to understand their aetiologies, working at the same time as the better-known Louis-Florentin Calmeil (1798-1895). We present a biography of this forgotten physician, a prolific writer, keen clinical observer and staunch devotee of a rigorous scientific approach. Copyright © 2015 Elsevier Masson SAS.

Jean-Anthelme Brillat-Savarin's 1825 treatise on the mouth and ingestion.

PubMed

Chong, Gabriel Tse Feng

2012-12-01

This article quotes and discusses Jean-Anthelme Brillat-Savarin's musings on the mouth and ingestion as described in his book The Physiology of Taste. The book was first published in France in December 1825, and is still widely read as a key work in Gastronomy today. The mouth is intimately related to the acts of chewing, swallowing and eating and it would be interesting to report an early 19th century epicurean's views on the mouth. Passages from Brillat-Savarin's book describing the functions of the teeth and tongue and the acts of tasting, chewing, and swallowing are quoted in full. Anecdotes also include one on the horrifying punishment of having one's tongue removed and another illustrating the poor oral health found among Europeans of that era. His work offers a unique glimpse into how a 19th century gastronome viewed the oral cavity and its gastronomical functions. While some of his writings may appear archaic and antediluvian to the modern reader; others relating to, for example chewing and swallowing, are surprisingly accurate by contemporary standards. Nonetheless, the gastronomic savant seemed to know a lot right about modern stomatology! Copyright © 2012. Published by Elsevier B.V.

Dominique Jean Larrey (1766-1842) has been described as the father of modern military surgery and is considered even today as the model military surgeon. He developed a plan of rapid evacuation of wounded soldiers from the battlefield during combat, using flexible medical units which he named ambulances volantes ("flying ambulances"). He won the admiration of Napoleon Bonaparte (1769-1821), who was amazed by the results of Larrey's sanitary system. Larrey spent almost 18 years with Napoleon, accompanying him in 25 campaigns, 60 battles, and more than 400 engagements. Napoleon's enormous military success was due not only to his strategy and skill but also to the medical services provided by Larrey. The surgeon became a master of wound management and limb amputation. In his vivid battlefield journals, Larrey documented the course of tetanus, the pathophysiology of cold injury, the effective control of hemorrhage, the drainage of empyema and hemothorax, the aspiration of pericardial effusion or hemopericardium, and the packing of sucking chest wounds. Larrey established a categorical rule for the triage of war casualties, treating the wounded according to the observed gravity of their injuries and the urgency for medical care, regardless of their rank or nationality.

EIT and the Popular Imagination

The Extreme ultraviolet Imaging Telescope on board SOHO, designed and built by Principal Investigator Jean-Pierre Delaboudiniere and his French/Belgan/US team, has produced numerous scientific breakthroughs, and has become both the standard coronal finder telescope and the determinant of whether halo coronal mass ejections are earthward-directed. Due to the dramatic nature of the images produced by EIT over the last nearly ten years, those images have been adopted worldwide in a manner no one could have foreseen before the launch of SOHO. I examine a small sample of the many scientific, commercial, and cultural uses of EIT imagery from the last decade in order to demonstrate how well-visualized, scientific imagery can first penetrate and then become an accepted part of the popular imagination.

The Hawthorne experiments and the introduction of Jean Piaget in American industrial psychology, 1929-1932.

PubMed

Hsueh, Yeh

2002-05-01

The Hawthorne interview program between 1929 and 1932 was one of the most significant industrial studies in the United States. The Hawthorne researchers applied Jean Piaget's clinical method in their extensive interviews with tens of thousands of workers. Chiefly responsible for the program's methodology was Elton Mayo, an Australian who saw interviewing as a means to promote social cooperation. Previous discussions of the Hawthorne experiments have ignored the influence of Piaget in the social sciences. This article provides an account of Mayo's and the Hawthorne researchers' efforts to fuse Piaget's innovation with burgeoning American industrial psychology. The endeavor was not an isolated event but rather drew on the theories and practice of Janet-Piaget psychology, on the support of the Laura Spelman Rockefeller Memorial Foundation, and on the discourse among social scientists about Piaget's work.

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

PubMed

Dourley, John

2015-02-01

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

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

PubMed

Veenstra, Gerry

2018-02-01

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

Chinese vegetative materia medica in a venereological treatise by Jean Astruc from 1740.

PubMed

Drobnik, Jacek

2016-07-01

Historical medical sources can be still queried for forgotten cures and remedies. Traditional Chinese medicine has dealt with lues venerea (syphilis) since the Five Dynasties period (10th century). Chinese indigenous materia medica and remedies recorded, studied or imported by the Europeans can reveal known or quite unknown medicinal plants. The studied Jean Astruc's work is a published ethnopharmacological survey carried out in Beijing in the 1730s and it deserves a modern interpretation. This is the first proposal to identify historical Chinese medicinal plants listed in a scarcely known medical treatise De Morbis venereis… ('On venereal diseases…') by Jean Astruc from 1740. I searched for the current uses and position of the taxonomically identified herbal stock in both traditional Chinese and official medical knowledge, with special attention to syphilis. Chinese names of drugs and their botanical identities (originally expressed by means of pre-Linnaean polynomials, and now interpreted as accepted binomials) were independently cross-checked with younger till most recent taxonomical and ethnopharmacological sources. Plants and drugs identified this way were queried for their modern applications in traditional Chinese and official medicine with special attention to sexually transmitted diseases (STD) and other uses which are similar to the 18th-century understanding of venereology. For 24 items of medicinal stock, 34 medicinal plants have been identified or suspected: Acacia catechu, Achyranthes bidentata, Akebia quinata, Angelica dahurica, A. sinensis, Aquilaria sinensis, Aralia cordata, Aristolochia fangchi, Chaenomeles sinensis, Ch. speciosa, Clematis vitalba, Coix lacryma-jobi, Commiphora myrrha, Cydonia oblonga, Daemonorops draco, D. jenkinsiana, Dictamnus dasycarpus, Dryobalanops sumatrensis, Forsythia suspensa, Glycyrrhiza uralensis, Lonicera confusa, L. hypoglauca, L. japonica, Ligusticum striatum (=L. chuanxiong), Piper kadsura, Pterocarpus

This stereoscopic image was generated by draping a Landsat satellite image over a preliminary Shuttle Radar Topography Mission (SRTM)elevation model. Two differing perspectives were then calculated, one for each eye. They can be seen in 3-D by viewing the left image with the right eye and the right image with the left eye (cross-eyed viewing), or by downloading and printing the image pair and viewing them with a stereoscope. When stereoscopically merged, the result is a vertically exaggerated view of the Earth's surface in its full three dimensions.

2010-01-01

We introduce a special issue of Ethos devoted to the work of Jerome Bruner and his careerlong attempts to seek innovative ways to foster a dialogue between psychology and anthropology. The articles in this special issue situate Bruner's meaning-centered approach to psychology and his groundbreaking work on narrative in the broader context of the developmental trajectory of both of fields of inquiry. Bruner's work has been enormously influential in the subfields of cultural psychology and psychological anthropology, especially because of his important contributions to our understanding of the intimate relationship between culture and mind. We examine Bruner's past and ongoing engagement with such luminary figures as Lev Vygotsky, Jean Piaget, Alfred Kroeber, Claude Lévi-Strauss, and Clifford Geertz to highlight points of convergence and tension between his version of cultural psychology and contemporary theorizing and practice in psychological anthropology. We also review his practical and theoretical contributions to the fields of medicine, law, and education. PMID:20706551

Although Hubble is operating normally and conducting its scientific observations, only three of its six gyroscopes are working properly. Four EVA's are planned to make the necessary repairs and replacements on the telescope. The STS-103 crew members are Commander Curtis L. Brown Jr., Pilot Scott J. Kelly, Steven L. Smith, C. Michael Foale (Ph.D.), John M. Grunsfeld (Ph.D.), and Claude Nicollier of Switzerland and Jean-Frangois Clervoy of France, both with the European Space Agency.

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

[Jean-Jacques Rosseau the vitalist. The moralization of medical hygiene between diet and ethical food].

Menin, Marco

The historiographical prejudice that sees in Jean-Jacques Rousseau an implacable opponent of scientific knowledge has long prevented an objective evaluation of the important influence that medical thought exerted over his philosophy. The aim of this paper is to show not only Rousseau's familiarity with the most important expressions of eighteenth-century medical literature, but also his willingness to incorporate some medical suggestions in his philosophical and literary production. In the first part of this article, I try to show how Rousseau's sensibility theory presupposes precise medical ideals, related to Montpellier School of vitalism. In the second part, I stress how Rousseau's philosophy of alimentation (which has clear anthropological and political implications) can be regarded as a genuine application of an ambition typical of vitalism: to use medical hygiene, also and above all, for moral purpose.

Thermal Jeans Fragmentation within ∼1000 au in OMC-1S

We present subarcsecond 1.3 mm continuum ALMA observations toward the Orion Molecular Cloud 1 South (OMC-1S) region, down to a spatial resolution of 74 au, which reveal a total of 31 continuum sources. We also present subarcsecond 7 mm continuum VLA observations of the same region, which allow further study of fragmentation down to a spatial resolution of 40 au. By applying a method of “mean surface density of companions” we find a characteristic spatial scale at ∼560 au, and we use this spatial scale to define the boundary of 19 “cores” in OMC-1S as groupings of millimeter sources. We find an additional characteristic spatial scale at ∼2800 au, which is the typical scale of the filaments in OMC-1S, suggesting a two-level fragmentation process. We measured the fragmentation level within each core and find a higher fragmentation toward the southern filament. In addition, the cores of the southern filament are also the densest cores (within 1100 au) in OMC-1S. This is fully consistent with previous studies of fragmentation at spatial scales one order of magnitude larger, and suggests that fragmentation down to 40 au seems to be governed by thermal Jeans processes in OMC-1S.

Summary The founder of physiology studies in the Balkans and the pioneer of research on hypothermia, Ivan Djaja (Jean Giaja) was born 1884 in L’Havre. Giaja gained his PhD at the Sorbonne in 1909. In 1910 he established the first Chair of Physiology in the Balkans and organized the first Serbian Institute for Physiology at the School of Philosophy of the University of Belgrade. He led this Institute for more than 40 subsequent years. His most notable papers were in the field of thermoregulation and bioenergetics. Djaja became member of the Serbian and Croatian academies of science and doctor honoris causa of Sorbonne. In 1952 for the seminal work on the behaviour of deep cooled warm blooded animals he becane associate member of the National Medical Academy in Paris. In 1955 the French Academy of Sciences elected him as associate member in place of deceased Sir Alexander Fleming. Djaja died in 1957 during a congress held in his honour. He left more than 200 scientific and other papers and the golden DaVincian credo “Nulla dies sine experimento”. His legacy was continued by several generations of researchers, the most prominent among them being Stefan Gelineo, Radoslav Andjus and Vojislav Petrović. PMID:21777022

Nutrient status of the lowbush blueberry, Lac-Saint-Jean area, Quebec, Canada. [Vaccinium angustifolium

The lowbush blueberry (Vaccinium angustifolium Ait.) is an important commercial crop of the Lac-Saint-Jean area (Quebec, Canada). The major blueberry fields are located on sandy soils relatively poor in available mineral nutrients. The nutrients originate from a thin organic layer found on the top of these sandy soils. The leaf mineral contents (N, P, K, Mg, Ca, Mn, Fe, Cu, Zn and B) were measured in five blueberry fields during 1984 and 1985. Soil pH and soil available P, K, and Mg were also assessed. The results show that the leaf mineral contents are generally adequate. However, K and Znmore » might be occasionally deficient when compared to the actual established standards. The available Mg in soil was significantly correlated with the leaf Mg concentration. The data also suggest that the influence of the pH following the burn pruning seems to influence the nutrition of this species.« less

Sainte-Anne Hospital is the largest psychiatric hospital in Paris. Its long and fascinating history began in the 18th century. In 1952, it was at Sainte-Anne Hospital that Jean Delay and Pierre Deniker used the first neuroleptic, chlorpromazine, to cure psychiatric patients, putting an end to the expansion of psychosurgery. The Department of Neuro-psychosurgery was created in 1941. The works of successive heads of the Neurosurgery Department at Sainte-Anne Hospital summarized the history of psychosurgery in France. Pierre Puech defined psychosurgery as the necessary cooperation between neurosurgeons and psychiatrists to treat the conditions causing psychiatric symptoms, from brain tumors to mental health disorders. He reported the results of his series of 369 cases and underlined the necessity for proper follow-up and postoperative re-education, illustrating the relative caution of French neurosurgeons concerning psychosurgery. Marcel David and his assistants tried to follow their patients closely postoperatively; this resulted in numerous publications with significant follow-up and conclusions. As early as 1955, David reported intellectual degradation 2 years after prefrontal leucotomies. Jean Talairach, a psychiatrist who eventually trained as a neurosurgeon, was the first to describe anterior capsulotomy in 1949. He operated in several hospitals outside of Paris, including the Sarthe Psychiatric Hospital and the Public Institution of Mental Health in the Lille region. He developed stereotactic surgery, notably stereo-electroencephalography, for epilepsy surgery but also to treat psychiatric patients using stereotactic lesioning with radiofrequency ablation or radioactive seeds of yttrium-90. The evolution of functional neurosurgery has been marked by the development of deep brain stimulation, in particular for obsessive-compulsive disorder, replacing the former lesional stereotactic procedures. The history of Sainte-Anne Hospital's Neurosurgery Department sheds

This review celebrates the events of 100 years ago to the month of publication of this December 1998 issue of the British Journal of Radiology, when radium was discovered by the Curies. This followed the earlier discovery in November 1895 of X-rays by Röntgen, which has already been reviewed in the British Journal of Radiology [1] and the discovery in March 1896, by Becquerel, of the phenomenon of radioactivity, which introduces this review. This is particularly relevant as Marie Curie was in 1897 a research student in Becquerel's laboratory. Marie Curie's life in Poland prior to her 1891 departure for Paris is included in this review as are other aspects of her life and work such as her work in World War I with radiological ambulances (known as "Little Curies") on the battlefields of France and Belgium, early experiments with radium and the founding of the Institut du Radium in Paris and of the Radium Institute in Warsaw. Wherever possible I have included appropriate quotations in Marie Curie's own words [2-4] and each section is related in some way to the life and work of Maria or Pierre. This review is completed with details of the re-interment of the bodies of Pierre and Marie on 20 April 1995 in The Panthéon, Paris.

Prototype muon detectors for the AMIGA component of the Pierre Auger Observatory

DOE PAGES

Aab, Alexander

2016-02-17

AMIGA (Auger Muons and Infill for the Ground Array) is an upgrade of the Pierre Auger Observatory to extend its range of detection and to directly measure the muon content of the particle showers. It consists of an infill of surface water-Cherenkov detectors accompanied by buried scintillator detectors used for muon counting. The main objectives of the AMIGA engineering array, referred to as the Unitary Cell, are to identify and resolve all engineering issues as well as to understand the muon-number counting uncertainties related to the design of the detector. The mechanical design, fabrication and deployment processes of the muonmore » counters of the Unitary Cell are described in this document. These muon counters modules comprise sealed PVC casings containing plastic scintillation bars, wavelength-shifter optical fibers, 64 pixel photomultiplier tubes, and acquisition electronics. The modules are buried approximately 2.25 m below ground level in order to minimize contamination from electromagnetic shower particles. The mechanical setup, which allows access to the electronics for maintenance, is also described in addition to tests of the modules' response and integrity. As a result, the completed Unitary Cell has measured a number of air showers of which a first analysis of a sample event is included here.« less

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

NASA Astrophysics Data System (ADS)

Lozano Bahilo, Julio; Pierre Auger Collaboration

2012-06-01

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

The Surface Detector of the Pierre Auger Observatory is sensitive to neutrinos of all flavors above 0.1 EeV. These interact through charged and neutral currents in the atmosphere giving rise to extensive air showers. When interacting deeply in the atmosphere at nearly horizontal incidence, neutrinos can be distinguished from regular hadronic cosmic rays by the broad time structure of their shower signals in the water-Cherenkov detectors. In this paper we present for the first time an analysis based on down-going neutrinos. We describe the search procedure, the possible sources of background, the method to compute the exposure and the associated systematic uncertainties. No candidate neutrinos have been found in data collected from 1 January 2004 to 31 May 2010. Assuming an E-2 differential energy spectrum the limit on the single-flavor neutrino is E2dN/dE<1.74×10-7GeVcm-2s-1sr-1 at 90% C.L. in the energy range 1×1017eV

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

We present the results of an analysis of data recorded at the Pierre Auger Observatory in which we search for groups of directionally-aligned events (or 'multiplets') which exhibit a correlation between arrival direction and the inverse of the energy. These signatures are expected from sets of events coming from the same source after having been deflected by intervening coherent magnetic fields. The observation of several events from the same source would open the possibility to accurately reconstruct the position of the source and also measure the integral of the component of the magnetic field orthogonal to the trajectory of the cosmic rays. We describe the largest multiplets found and compute the probability that they appeared by chance from an isotropic distribution. We find no statistically significant evidence for the presence of multiplets arising from magnetic deflections in the present data.

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

IN SITU AND LABORATORY GEOTECHNICAL TESTS OF THE PIERRE SHALE NEAR HAYES, SOUTH DAKOTA - A CHARACTERIZATION OF ENGINEERING BEHAVIOR.

1986-01-01

A geotechnical investigation of the Pierre Shale near Hayes, South Dakota, was conducted by the U. S. Geological Survey as a basis for evaluating problems in deep excavations into that formation. The physical and mechanical properties of the shale were determined through use of core holes drilled to a maximum depth of 184 m. In situ borehole determinations included a gravimeter survey, pressuremeter testing, thermal profile measurements, and borehole velocity measurements. Onsite and offsite laboratory measurements included rebound measurements, sonic velocity measurements of shear and primary waves, X-ray mineralogy and major element determinations, size analyses, fracture analyses, fabric analyses, and determination of thermal properties. The properties of the clay shale indicate problems that may be encountered in excavation and use of deep underground facilities.

Elves, Forbush Decreases and Solar Activity Studies at the Pierre Auger Observatory

NASA Astrophysics Data System (ADS)

Colalillo, Roberta

The Pierre Auger Observatory, designed to observe cosmic rays at the highest energies, can also be a valid ground based instrument for the observation of transient luminous events and for studying the modulation of galactic cosmic rays due to solar activity. The Fluorescence Detector can observe elves, transient luminous emissions from altitudes between 80 and 95 km above sea level, with timescales of tens of microseconds, which are triggered by lightning activity. A dedicated trigger and an extended readout scheme were introduced to enhance detection efficiency of these events and to improve the knowledge of some peculiar characteristics. The low energy mode of the Surface Detector, on the other hand, records variations in the flux of low energy secondary particles with extreme detail. With the Scaler mode, it is possible to register the rate of signals for deposited energies between 15-100 MeV; the Histogram mode, using the calibration peak and charge histograms of the individual pulses detected by each water-Cherenkov station, covers different deposited energy ranges up to 1 GeV. The variations in the flux of galactic cosmic rays have been studied on short and intermediate time scales (Forbush decreases), but also a long-term analysis, which shows the sensitivity of the Observatory to the solar cycle variation, is in progress.

In recent years, we have worked with many psychiatric records kept by the Archive Services of the Institut universitaire en santé mentale de Montréal (IUSMM). The proposed article is focused on the February 12th 1959 document Assemblée des médecins located within the records of six illegitimate children admitted to the Hôpital Saint-Jean-de-Dieu in the late 1950s. Our study, inspired by the work of historian Roy Porter and his approach from below, contributes to the historical discourse seeking to incorporate patient's voices, in this case, a gang of young offenders identified by a life course shaped by repeated institutional experience.

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

Search for signatures of magnetically-induced alignment in the arrival directions measured by the Pierre Auger Observatory

We present the results of an analysis of data recorded at the Pierre Auger Observatory in which we search for groups of directionally-aligned events (or ''multiplets'') which exhibit a correlation between arrival direction and the inverse of the energy. These signatures are expected from sets of events coming from the same source after having been deflected by intervening coherent magnetic fields. The observation of several events from the same source would open the possibility to accurately reconstruct the position of the source and also measure the integral of the component of the magnetic field orthogonal to the trajectory of themore » cosmic rays. We describe the largest multiplets found and compute the probability that they appeared by chance from an isotropic distribution. We find no statistically significant evidence for the presence of multiplets arising from magnetic deflections in the present data.« less

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

Weighing the galactic disc using the Jeans equation: lessons from simulations

NASA Astrophysics Data System (ADS)

Candlish, G. N.; Smith, R.; Moni Bidin, C.; Gibson, B. K.

Using three-dimensional stellar kinematic data from simulated galaxies, we examine the efficacy of a Jeans equation analysis in reconstructing the total disk surface density, including the dark matter, at the `Solar' radius. Our simulation data set includes galaxies formed in a cosmological context using state-of-the-art high-resolution cosmological zoom simulations, and other idealized models. The cosmologically formed galaxies have been demonstrated to lie on many of the observed scaling relations for late-type spirals, and thus offer an interesting surrogate for real galaxies with the obvious advantage that all the kinematical data are known perfectly. We show that the vertical velocity dispersion is typically the dominant kinematic quantity in the analysis, and that the traditional method of using only the vertical force is reasonably effective at low heights above the disk plane. At higher heights the inclusion of the radial force becomes increasingly important. We also show that the method is sensitive to uncertainties in the measured disk parameters, particularly the scalelengths of the assumed double exponential density distribution, and the scalelength of the radial velocity dispersion. In addition, we show that disk structure and low number statistics can lead to significant errors in the calculated surface densities. Finally, we examine the implications of our results for previous studies of this sort, suggesting that more accurate measurements of the scalelengths may help reconcile conflicting estimates of the local dark matter density in the literature.

Atmospheric conditions, such as the pressure (P), temperature (T) or air density (ρ propto P/T), affect the development of extended air showers initiated by energetic cosmic rays. We study the impact of the atmospheric variations on the reconstruction of air showers with data from the arrays of surface detectors of the Pierre Auger Observatory, considering separately the one with detector spacings of 1500 m and the one with 750 m spacing. We observe modulations in the event rates that are due to the influence of the air density and pressure variations on the measured signals, from which the energy estimators are obtained. We show how the energy assignment can be corrected to account for such atmospheric effects.

["Psychologus nemo, nisi Physiologus"--Johannes Müller and perspectives of médecine philosophique: a discovery from University's Archive].

PubMed

Scharbert, Gerhard

2010-01-01

Taking Johannes Müller's still little examined school education in then French Koblenz at its starting point, this paper argues that Miiller's pre-academic training in the applied sciences as well as in the old languages--which Müller saw as a basic essential for the philosophically educated naturalist--had a profound impact on the scientific-philosophical views he put forward in his Dissertatio inauguralis physiologica sistens commentarios de phoronomia animalium published in 1822. The Dissertatio was influenced, in particular, by the work of Pierre-Jean-Georges Cabanis (1757-1808) and can be read as a physiological application of French Enlightenment sensualist philosophy. It shows that Müller already at early moment took up decisive impulses from revolutionary France. Also, a traditional mistake is shown to have falsified a fundamental aspect of this earliest work already with lasting effect.

Barbarism and Religion, the first half of J. G. A. Pocock's study of Gibbon's Decline and Fall, was designed to set Gibbon's work in context, using a method developed in Cambridge, by juxtaposing his narrative to many others-to some but not all of which he explicitly referred. Helena Rosenblatt has misunderstood Pocock's intent, which was to show that Gibbon's work took much of its inspiration for its treatment of Christianity from a world of ecclesiastical scholarship. Though Pierre Force shows that Voltaire's erudition was richer than has been thought, he and Gibbon pursued very different forms of learning. And though Pocock agrees with Jonathan Israel that many thinkers challenged traditional Christian theology, their efforts were far more varied than Israel holds. Brief studies of Jean LeClerc and Ralph call Israel's vision of radical Enlightenment into question.

How molecular motors work – insights from the molecular machinist's toolbox: the Nobel prize in Chemistry 2016

PubMed Central

Astumian, R. D.

2017-01-01

The Nobel prize in Chemistry for 2016 was awarded to Jean Pierre Sauvage, Sir James Fraser Stoddart, and Bernard (Ben) Feringa for their contributions to the design and synthesis of molecular machines. While this field is still in its infancy, and at present there are no commercial applications, many observers have stressed the tremendous potential of molecular machines to revolutionize technology. However, perhaps the most important result so far accruing from the synthesis of molecular machines is the insight provided into the fundamental mechanisms by which molecular motors, including biological motors such as kinesin, myosin, FoF1 ATPase, and the flagellar motor, function. The ability to “tinker” with separate components of molecular motors allows asking, and answering, specific questions about mechanism, particularly with regard to light driven vs. chemistry driven molecular motors.

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

We present a short historical review of the major figures, their administrative functions and their works that contributed to make Paris a renowned centre of physiology and neurology during the xixth and the first half of the xxth century. We purposely chose to focus on the period 1800-1950, as 1800 corresponds to the actual beginning of neurosciences, and 1950 marks their exponential rise. Our presentation is divided into four chapters, matching the main disciplines which have progressed and contributed the most to the knowledge we have of the brain sciences: anatomy, physiology, neurology, and psychiatry-psychology. The present article is the third of four parts of this review, and deals with neurology. A special credit should be given to Jean-Martin Charcot who founded the Salpêtrière School of neurology and became one of the world's most important neurologists of the xixth century. We provide below the biographical sketches of Armand Trousseau, Guillaume Benjamin Amand Duchenne, Jean-Martin Charcot, Alfred Vulpian, Désiré-Magloire Bourneville, Paul Richer, Henri Parinaud, Albert Pitres, Jules Joseph Dejerine, Mrs. Augusta Dejerine-Klumpke, Édouard Brissaud, Pierre Marie, Georges Édouard Brutus Gilles de la Tourette, Joseph Babinski, André Thomas, Georges Marinesco, Achille Alexandre Souques, Georges Guillain and Charles Foix.

BOOK REVIEW: Jean-Charles Houzeau et son temps

NASA Astrophysics Data System (ADS)

Sterken, C.; Verhas, P.

2002-12-01

This is a wonderful book. It describes the life and work of Belgian astronomer Jean-Charles Houzeau (1820-1888) and, as the last three words of the title indicate, it has a broader focus including the social, industrial and scientific context of the second part of the 19th century. This is set in a very broad international social context including social revolutions in Belgium and France, and the abolition of slavery in the United States. The biography clearly shows that this hard-working man was driven by science and justice, by individualism and generosity, by humor and sentiment. The book is divided in four parts, each part is placed in its own historical context. The first part "The apprentice, the master and his disciples" describes Houzeau's childhood and young years, his early scientific career at the Observatory in Brussels, and his relationship with Adolphe Quetelet. The evolution of this relationship is very well documented: the turbulent revolutionary Houzeau versus cool, moderated and diplomatic royalist Quetelet, the observer versus the mathematician theorist. But both were very dedicated teachers: Quetelet established public courses and after the Revolution of 1830 he contributed to the foundation of the University of Brussels; Houzeau was the peripatetic teacher wherever place he was, also after his return to Belgium. The second part is "The politician" and deals with Houzeau's political ideas and revolutionary attitudes and their consequences. His revolutionary ideas, though, were not confined to politics only: he also severely criticised the paucity of high-precision observations collected at the Royal Observatory in his days. Because he participated at revolutionary meetings, Houzeau was fired from his position at the Observatory by the Minister of Interior Affairs Charles Rogier. Thus started his peripathetic life, covering observational work in astronomy, geography, geodesy and natural sciences in many places in Belgium and abroad. The third

Some historical reflections on the neural control of locomotion.

PubMed

Clarac, François

2008-01-01

Thought on the neural control of locomotion dates back to antiquity. In this article, however, the focus is more recent by starting with some major 17th century concepts, which were developed by René Descartes, a French philosopher; Thomas Willis, an English anatomist; and Giovanni Borelli, an Italian physiologist and physicist. Each relied on his personal expertise to theorize on the organization and control of movements. The 18th and early 19th centuries saw work on both the central and peripheral control of movement: the former most notably by Johann Unzer, Marie Jean-Pierre Flourens and Julien-Jean-César Legallois, and the latter by Unzer, Jirí Procháska and many others. Next in the 19th century, neurologists used human locomotion as a precise tool for characterizing motor pathologies: e.g., Guillaume Duchenne de Boulogne's description of locomotor ataxia. Jean-Martin Charcot considered motor control to be organized at two levels of the central nervous system: the cerebral cortex and the spinal cord. Maurice Philippson's defined the dog's step cycle and considered that locomotion used both central and reflex mechanisms. Charles Sherrington explained that locomotor control was usually thought to consist of a succession of peripheral reflexes (e.g., the stepping reflexes). Thomas Graham Brown's then contemporary evidence for the spinal origin of locomotor rhythmicity languished in obscurity until the early 1960s. By then the stage was set for an international assault on the neural control of locomotion, which featured research conducted on both invertebrate and vertebrate animal models. These contributions have progressively became more integrated and interactive, with current work emphasizing that locomotor control involves a seamless integration between central locomotor networks and peripheral feedback.

Interactions of Pannexin1 channels with purinergic and NMDA receptor channels.

PubMed

Li, Shuo; Bjelobaba, Ivana; Stojilkovic, Stanko S

2018-01-01

Pannexins are a three-member family of vertebrate plasma membrane spanning molecules that have homology to the invertebrate gap junction forming proteins, the innexins. However, pannexins do not form gap junctions but operate as plasma membrane channels. The best-characterized member of these proteins, Pannexin1 (Panx1) was suggested to be functionally associated with purinergic P2X and N-methyl-D-aspartate (NMDA) receptor channels. Activation of these receptor channels by their endogenous ligands leads to cross-activation of Panx1 channels. This in turn potentiates P2X and NMDA receptor channel signaling. Two potentiation concepts have been suggested: enhancement of the current responses and/or sustained receptor channel activation by ATP released through Panx1 pore and adenosine generated by ectonucleotidase-dependent dephosphorylation of ATP. Here we summarize the current knowledge and hypotheses about interactions of Panx1 channels with P2X and NMDA receptor channels.

Mass composition studies of Ultra High Energy cosmic rays through the measurement of the Muon Production Depths at the Pierre Auger Observatory

DOE Office of Scientific and Technical Information (OSTI.GOV)

Collica, Laura

The Pierre Auger Observatory (Auger) in Argentina studies Ultra High Energy Cosmic Rays (UHECRs) physics. The flux of cosmic rays at these energies (above 1018 eV) is very low (less than 100 particle/km2-year) and UHECR properties must be inferred from the measurements of the secondary particles that the cosmic ray primary produces in the atmosphere. These particles cascades are called Extensive Air Showers (EAS) and can be studied at ground by deploying detectors covering large areas. The EAS physics is complex, and the properties of secondary particles depend strongly on the first interaction, which takes place at an energy beyondmore » the ones reached at accelerators. As a consequence, the analysis of UHECRs is subject to large uncertainties and hence many of their properties, in particular their composition, are still unclear. Two complementary techniques are used at Auger to detect EAS initiated by UHE- CRs: a 3000 km2 surface detector (SD) array of water Cherenkov tanks which samples particles at ground level and fluorescence detectors (FD) which collect the ultraviolet light emitted by the de-excitation of nitrogen nuclei in the atmosphere, and can operate only in clear, moonless nights. Auger is the largest cosmic rays detector ever built and it provides high-quality data together with unprecedented statistics. The main goal of this thesis is the measurement of UHECR mass composition using data from the SD of the Pierre Auger Observatory. Measuring the cosmic ray composition at the highest energies is of fundamental importance from the astrophysical point of view, since it could discriminate between different scenarios of origin and propagation of cosmic rays. Moreover, mass composition studies are of utmost importance for particle physics. As a matter of fact, knowing the composition helps in exploring the hadronic interactions at ultra-high energies, inaccessible to present accelerator experiments.« less

A Search for Ultra-High Energy Neutrinos in Highly Inclined Events at the Pierre Auger Observatory

DOE PAGES

Abreu, P

2011-12-30

The Surface Detector of the Pierre Auger Observatory is sensitive to neutrinos of all flavors above 0.1 EeV. These interact through charged and neutral currents in the atmosphere giving rise to extensive air showers. When interacting deeply in the atmosphere at nearly horizontal incidence, neutrinos can be distinguished from regular hadronic cosmic rays by the broad time structure of their shower signals in the water-Cherenkov detectors. In this paper we present for the first time an analysis based on down-going neutrinos. We describe the search procedure, the possible sources of background, the method to compute the exposure and the associatedmore » systematic uncertainties. No candidate neutrinos have been found in data collected from 1 January 2004 to 31 May 2010. Assuming an E -2 differential energy spectrum the limit on the single-flavor neutrino is E 2dN/dE < 1.74 x 10 -7 GeV cm -2s -1sr -1 at 90% C.L. in the energy range 1 x 10 17eV < E < 1 x 10 20 eV.« less

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

The Pierre Auger Collaboration has reported evidence for anisotropy in the distribution of arrival directions of the cosmic rays with energies E > Eth = 5.5 × 1019 eV. These show a correlation with the distribution of nearby extragalactic objects, including an apparent excess around the direction of Centaurus A. If the particles responsible for these excesses at E > Eth are heavy nuclei with charge Z, the proton component of the sources should lead to excesses in the same regions at energies E/Z. We here report the lack of anisotropies in these directions at energies above Eth/Z (for illustrative values of Z = 6,13,26). If the anisotropies above Eth are due to nuclei with charge Z, and under reasonable assumptions about the acceleration process, these observations imply stringent constraints on the allowed proton fraction at the lower energies.

In infants with Pierre Robin syndrome (PRS), mandibular distraction may be more advantageous than glossopexy as it not only relieves oropharyngeal airway obstruction but also reverses body growth retardation. Because no data are available on body weight velocity after glossopexy, we assessed longitudinally the body weight velocity in a cohort of children undergoing glossopexy. The records of 48 infants with PRS undergoing glossopexy after unsuccessful nonoperative treatment between 1981 and 2005 were reviewed. Weight measurements were analyzed at 4 time-points: at birth, on admission for glossopexy, on admission for lysis of lip-tongue adhesion (TLA), and at follow-up. Weight velocity was assessed using Tanner's tables. Adhesion dehiscence occurred in 9 patients (18.7%). Lip-tongue adhesion resolved airway compromise in 36 infants (75%). Release of TLA was accomplished in 34 patients. Data on weight velocity from birth to follow-up (mean, 5.57 +/- 0.59 years) were available for 31 patients. After glossopexy, mean body weight increased from the 9.7 +/- 2.6th to the 17.5 +/- 4.6th percentile (P > .05), whereas mean weight velocity increased from the 19.1 +/- 4.9th to the 74.2 +/- 4.7th percentile (P < .001). No temporal correlation was found between glossopexy and oropharyngeal dysphagia. In infants with PRS, glossopexy is a valid alternative to mandibular distraction because it does not cause decline in body growth.

Muons in air showers at the Pierre Auger Observatory: Mean number in highly inclined events

DOE PAGES

Aab, Alexander

2015-03-09

We present the first hybrid measurement of the average muon number in air showers at ultra-high energies, initiated by cosmic rays with zenith angles between 62° and 80° . Our measurement is based on 174 hybrid events recorded simultaneously with the Surface Detector array and the Fluorescence Detector of the Pierre Auger Observatory. The muon number for each shower is derived by scaling a simulated reference profile of the lateral muon density distribution at the ground until it fits the data. A 10 19 eV shower with a zenith angle of 67°, which arrives at the Surface Detector array atmore » an altitude of 1450 m above sea level, contains on average (2.68 ± 0.04 ± 0.48 (sys.)) × 10 7 muons with energies larger than 0.3 GeV. Finally, the logarithmic gain d ln N µ/d ln E of muons with increasing energy between 4 × 10 18 eV and 5 × 10 19 eV is measured to be (1.029 ± 0.024 ± 0.030 (sys.)).« less

The advent of the Auger Engineering Radio Array (AERA) necessitates the development of a powerful framework for the analysis of radio measurements of cosmic ray air showers. As AERA performs “radio-hybrid” measurements of air shower radio emission in coincidence with the surface particle detectors and fluorescence telescopes of the Pierre Auger Observatory, the radio analysis functionality had to be incorporated in the existing hybrid analysis solutions for fluorescence and surface detector data. This goal has been achieved in a natural way by extending the existing Auger Offline software framework with radio functionality. In this article, we lay out the design, highlights and features of the radio extension implemented in the Auger Offline framework. Its functionality has achieved a high degree of sophistication and offers advanced features such as vectorial reconstruction of the electric field, advanced signal processing algorithms, a transparent and efficient handling of FFTs, a very detailed simulation of detector effects, and the read-in of multiple data formats including data from various radio simulation codes. The source code of this radio functionality can be made available to interested parties on request.

Depth of maximum of air-shower profiles at the Pierre Auger Observatory. II. Composition implications

DOE PAGES

Aab, A.; Abreu, P.; Aglietta, M.; ...

2014-12-01

Using the data taken at the Pierre Auger Observatory between December 2004 and December 2012, we have examined the implications of the distributions of depths of atmospheric shower maximum (Xmax), using a hybrid technique, for composition and hadronic interaction models. We do this by fitting the distributions with predictions from a variety of hadronic interaction models for variations in the composition of the primary cosmic rays and examining the quality of the fit. Regardless of what interaction model is assumed, we find that our data are not well described by a mix of protons and iron nuclei over most ofmore » the energy range. Acceptable fits can be obtained when intermediate masses are included, and when this is done consistent results for the proton and iron-nuclei contributions can be found using the available models. We observe a strong energy dependence of the resulting proton fractions, and find no support from any of the models for a significant contribution from iron nuclei. However, we also observe a significant disagreement between the models with respect to the relative contributions of the intermediate components.« less

Generalized Jeans' Escape of Pick-Up Ions in Quasi-Linear Relaxation

NASA Technical Reports Server (NTRS)

Moore, T. E.; Khazanov, G. V.

2011-01-01

Jeans escape is a well-validated formulation of upper atmospheric escape that we have generalized to estimate plasma escape from ionospheres. It involves the computation of the parts of particle velocity space that are unbound by the gravitational potential at the exobase, followed by a calculation of the flux carried by such unbound particles as they escape from the potential well. To generalize this approach for ions, we superposed an electrostatic ambipolar potential and a centrifugal potential, for motions across and along a divergent magnetic field. We then considered how the presence of superthermal electrons, produced by precipitating auroral primary electrons, controls the ambipolar potential. We also showed that the centrifugal potential plays a small role in controlling the mass escape flux from the terrestrial ionosphere. We then applied the transverse ion velocity distribution produced when ions, picked up by supersonic (i.e., auroral) ionospheric convection, relax via quasi-linear diffusion, as estimated for cometary comas [1]. The results provide a theoretical basis for observed ion escape response to electromagnetic and kinetic energy sources. They also suggest that super-sonic but sub-Alfvenic flow, with ion pick-up, is a unique and important regime of ion-neutral coupling, in which plasma wave-particle interactions are driven by ion-neutral collisions at densities for which the collision frequency falls near or below the gyro-frequency. As another possible illustration of this process, the heliopause ribbon discovered by the IBEX mission involves interactions between the solar wind ions and the interstellar neutral gas, in a regime that may be analogous [2].

Could Jean-Dominique Cassini see the famous division in Saturn's rings?

Nowadays, astronomers want to observe gaps in exozodiacal disks to confirm the presence of exoplanets, or even make actual images of these companions. Four hundred and fifty years ago, Jean-Dominique Cassini did a similar study on a closer object: Saturn. After joining the newly created Observatoire de Paris in 1671, he discovered 4 of Saturn's satellites (Iapetus, Rhea, Tethys and Dione), and also the gap in its rings. He made these discoveries observing through the best optics at the time, made in Italy by famous opticians like Giuseppe Campani or Eustachio Divini. But was he really able to observe this black line in Saturn's rings? That is what a team of optical scientists from Observatoire de Paris - LESIA with the help of Onera and Institut d'Optique tried to find out, analyzing the lenses used by Cassini, and still preserved in the collection of the observatory. The main difficulty was that even if the lenses have diameters between 84 and 239 mm, the focal lengths are between 6 and 50 m, more than the focal lengths of the primary mirrors of future ELTs. The analysis shows that the lenses have an exceptionally good quality, with a wavefront error of approximately 50 nm rms and 200 nm peak-to-valley, leading to Strehl ratios higher than 0.8. Taking into account the chromaticity of the glass, the wavefront quality and atmospheric turbulence, reconstructions of his observations tend to show that he was actually able to see the division named after him.

We study the impact of the atmospheric variations on the reconstruction of air showers with data from the arrays of surface detectors of the Pierre Auger Observatory, considering separately the one with detector spacings of 1500 m and the one with 750 m spacing. We observe modulations in the event rates that are due to the influence of the air density and pressure variations on the measured signals, from which the energy estimators are obtained. Lastly, we show how the energy assignment can be corrected to account for such atmospheric effects.« less

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

Among the mummies preserved in the Basilica of San Domenico Maggiore in Naples, there are the bodies of the wife and three children of Jean Antoine Michel Agar, Minister of Finance of Naple's Kingdom during the Monarchy of Joachim Murat (1808-1815). Between 1983 and 1987 paleopathological analyses were performed; in particular, X-ray examination allowed investigation of the health status of the Agar family members and reconstruction of the embalming processes used to preserve the bodies. In addition, an analysis of the historical and archival documents was carried out, to formulate hypotheses about the causes of death, demonstrating how these sources could become important instruments to obtain diagnoses and pathological histories.

The effect of the geomagnetic field on cosmic ray energy estimates and large scale anisotropy searches on data from the Pierre Auger Observatory

Abreu, P.; /Lisbon, IST; Aglietta, M.

2011-11-01

We present a comprehensive study of the influence of the geomagnetic field on the energy estimation of extensive air showers with a zenith angle smaller than 60{sup o}, detected at the Pierre Auger Observatory. The geomagnetic field induces an azimuthal modulation of the estimated energy of cosmic rays up to the {approx} 2% level at large zenith angles. We present a method to account for this modulation of the reconstructed energy. We analyse the effect of the modulation on large scale anisotropy searches in the arrival direction distributions of cosmic rays. At a given energy, the geomagnetic effect is shownmore » to induce a pseudo-dipolar pattern at the percent level in the declination distribution that needs to be accounted for. In this work, we have identified and quantified a systematic uncertainty affecting the energy determination of cosmic rays detected by the surface detector array of the Pierre Auger Observatory. This systematic uncertainty, induced by the influence of the geomagnetic field on the shower development, has a strength which depends on both the zenith and the azimuthal angles. Consequently, we have shown that it induces distortions of the estimated cosmic ray event rate at a given energy at the percent level in both the azimuthal and the declination distributions, the latter of which mimics an almost dipolar pattern. We have also shown that the induced distortions are already at the level of the statistical uncertainties for a number of events N {approx_equal} 32 000 (we note that the full Auger surface detector array collects about 6500 events per year with energies above 3 EeV). Accounting for these effects is thus essential with regard to the correct interpretation of large scale anisotropy measurements taking explicitly profit from the declination distribution.« less

To estimate the current birth prevalence of isolated and syndromic Pierre Robin sequence (iPRS and sPRS), including demographic variations. To assess for regional variations in surgical airway interventions for PRS, and to determine the mean length of stay (LOS), cost of admission, complication rate, and rate of associated procedures related to tongue-lip adhesion (TLA), neonatal mandibular distraction osteogenesis (MDO), and tracheotomy. Retrospective cross-sectional study. The 2006 and 2009 Kids Inpatient Databases were used to identify newborns and infants with PRS; analysis using cross tabulations and linear regression modeling was performed. In 2006 and 2009, the estimated birth prevalence of iPRS was 1.8:10,000 live births and sPRS 1.4:10,000 live births. The highest rate was in whites and the lowest in non-Hispanic blacks. There were 145 TLAs (36%), 176 MDOs (43%), and 85 tracheotomies (21%). The Northeast favored a TLA strategy; the Midwest favored MDO. The mean LOS for TLA was 24.5 days, MDO 36.7 days, tracheotomy (iPRS) 44.9 days, and tracheotomy (sPRS) 53.0 days. The birth prevalence of PRS may be higher than previously described, especially in whites. Surgical management strategies vary between regions. The overall cost of a TLA admission is lower than an MDO or tracheotomy admission, owing primarily to shorter LOS. This study was limited by not taking into account outpatient expenses (nursing care, monitoring) or need for further airway/feeding intervention over subsequent admissions. 2c. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

Anisotropy and chemical composition of ultra-high energy cosmic rays using arrival directions measured by the Pierre Auger Observatory

DOE PAGES

Abreu, P

2011-06-17

The Pierre Auger Collaboration has reported evidence for anisotropy in the distribution of arrival directions of the cosmic rays with energies E > E th = 5.5 x 10 19 eV. These show a correlation with the distribution of nearby extragalactic objects, including an apparent excess around the direction of Centaurus A. If the particles responsible for these excesses at E > E th are heavy nuclei with charge Z, the proton component of the sources should lead to excesses in the same regions at energies E/Z. We here report the lack of anisotropies in these directions at energies abovemore » E th/Z (for illustrative values of Z = 6,13,26). If the anisotropies above E th are due to nuclei with charge Z, and under reasonable assumptions about the acceleration process, these observations imply stringent constraints on the allowed proton fraction at the lower energies.« less

Claude Bernard Distinguished Lecture. Becoming a truly helpful teacher: considerably more challenging, and potentially more fun, than merely doing business as usual.

Few medical faculty members are adequately prepared for their instructional responsibilities. Our educational traditions were established before we had research-based understandings of the teaching-learning process and before brain research began informing our understandings of how humans achieve lasting learning. Yet, there are several advantages you may have. If your expertise is at one of the frontiers of human biology, your teaching can be inherently fascinating to aspiring health professionals. If your work has implications for human health, you have another potential basis for engaging future clinicians. And, thanks to Claude Bernard's influence, you likely are "process oriented," a necessary mindset for being an effective teacher. There are also challenges you may face. Your medical students will mostly become clinicians. Unless you can help them see connections between your offerings and their future work, you may not capture and sustain their interest. To be effective, teachers, like clinicians, need to be interactive, make on-the-spot decisions, and be "emotional literate." If you aren't comfortable with these demands, you may have work to do toward becoming a truly helpful teacher. Program changes may be needed. Might your program need to change 1) from being adversarial and controlling to being supportive and trust based or 2) from mainly dispensing information to mainly asking and inviting questions? In conclusion, making changes toward becoming a truly helpful teacher can bring benefits to your students while increasing your sense of satisfaction and fulfillment as a teacher. If you choose to change, be gentle with yourself, as you should be when expecting your students to make important changes.

We present a comprehensive study of the influence of the geomagnetic field on the energy estimation of extensive air showers with a zenith angle smaller than 60°, detected at the Pierre Auger Observatory. The geomagnetic field induces an azimuthal modulation of the estimated energy of cosmic rays up to the ~ 2% level at large zenith angles. We present a method to account for this modulation of the reconstructed energy. We analyse the effect of the modulation on large scale anisotropy searches in the arrival direction distributions of cosmic rays. At a given energy, the geomagnetic effect is shown to induce a pseudo-dipolar pattern at the percent level in the declination distribution that needs to be accounted for.

Most civil engineering structures have been built in the 50's and 60's and reach similar level of degradation accelerated by loading conditions and corrosion. In Europe, National Authorities and the European Commission promote Health Monitoring concepts, instrumentation of existing structures and help in the design of new durable structures of higher performance. In this context, the CEA-List has achieved a non-exclusive industrial transfer of its Bragg grating sensing technology for civil engineering applications to Hydrolog (French SME), supported by the European Community and the french ministry of Industry. In order to check the reliability and user-friendliness of this instrumentation, eleven spectrally-multiplexed Bragg grating-based extensometers, four FBG temperature sensors and an acquisition unit have been installed into the Saint-Jean bridge in Bordeaux, France with the help of the Infrastructure Regional Direction (DRE-Aquitaine) and the Bordeaux Authority (Communaute Urbaine de Bordeaux). A standardized loading of the bridge has been performed on October 29, 1001, with the purpose of correlating its mechanical reaction to loading conditions. Moreover, the equipment has been operating for one year to take into account the winter-summer cycle.

Monitoring of mirror degradation of fluorescence detectors at the Pierre Auger Observatory due to dust sedimentation

We present results of the monitoring method we have used to characterize the optical performance deterioration due to the dust of our mirror segments produced for fluorescence detectors used in astrophysics experiments. The method is based on the measurement of scatter profiles of reflected light. The scatter profiles and the reflectivity of the mirror segments sufficiently describe the performance of the mirrors from the perspective of reconstruction algorithms. The method is demonstrated on our mirror segments installed in frame of the Pierre Auger Observatory project. Although installed in air-conditioned buildings, both the dust sedimentation and the natural aging of the reflective layer deteriorate the optical throughput of the segments. In the paper, we summarized data from ten years of operation of the fluorescence detectors. During this time, we periodically measured in-situ scatter characteristics represented by the specular reflectivity and the reflectivity of the diffusion part at the wavelength of 670 nm of the segment surface (measured by means of the optical scatter technique as well). These measurements were extended with full Bidirectional Reflectance Distribution Functions (BRDF) profiles of selected segments made in the laboratory. Cleaning procedures are also discussed in the paper.

Neutrinos in the cosmic ray flux with energies near 1 EeV and above are detectable with the Surface Detector array (SD) of the Pierre Auger Observatory. We report here on searches through Auger data from 1 January 2004 until 20 June 2013. No neutrino candidates were found, yielding a limit to the diffuse flux of ultrahigh energy neutrinos that challenges the Waxman-Bahcall bound predictions. Neutrino identification is attempted using the broad time structure of the signals expected in the SD stations, and is efficiently done for neutrinos of all flavors interacting in the atmosphere at large zenith angles, as well as for "Earth-skimming" neutrino interactions in the case of tau neutrinos. In this paper the searches for downward-going neutrinos in the zenith angle bins 60°-75° and 75°-90° as well as for upward-going neutrinos, are combined to give a single limit. The 90% C.L. single-flavor limit to the diffuse flux of ultrahigh energy neutrinos with an E-2 spectrum in the energy range 1.0 ×1 017 eV - 2.5 ×1 019 eV is Eν2d Nν/d Eν<6.4 ×10-9 GeV cm-2 s-1 sr-1 .

Measurement of the Muon Atmospheric Production Depth with the Water Cherenkov Detectors of the Pierre Auger Observatory

Molina Bueno, Laura

Ultra-high-energy cosmic rays (UHECR) are particles of uncertain origin and composition, with energies above 1 EeV (10 18 eV or 0.16 J). The measured flux of UHECR is a steeply decreasing function of energy. The largest and most sensitive apparatus built to date to record and study cosmic ray Extensive Air Showers (EAS) is the Pierre Auger Observatory. The Pierre Auger Observatory has produced the largest and finest amount of data ever collected for UHECR. A broad physics program is being carried out covering all relevant topics of the field. Among them, one of the most interesting is the problemmore » related to the estimation of the mass composition of cosmic rays in this energy range. Currently the best measurements of mass are those obtained by studying the longitudinal development of the electromagnetic part of the EAS with the Fluorescence Detector. However, the collected statistics is small, specially at energies above several tens of EeV. Although less precise, the volume of data gathered with the Surface Detector is nearly a factor ten larger than the fluorescence data. So new ways to study composition with data collected at the ground are under investigation. The subject of this thesis follows one of those new lines of research. Using preferentially the time information associated with the muons that reach the ground, we try to build observables related to the composition of the primaries that initiated the EAS. A simple phenomenological model relates the arrival times with the depths in the atmosphere where muons are produced. The experimental confirmation that the distributions of muon production depths (MPD) correlate with the mass of the primary particle has opened the way to a variety of studies, of which this thesis is a continuation, with the aim of enlarging and improving its range of applicability. We revisit the phenomenological model which is at the root of the analysis and discuss a new way to improve some aspects of the model. We carry out

To evaluate costs associated with surgical treatment for neonates with Pierre Robin sequence (PRS). Retrospective cohort study. Cincinnati Children's Hospital Medical Center. With Institutional Review Board approval, we retrospectively studied neonates with PRS treated from 2001 to 2009 with either tracheostomy (Trach), mandibular distraction (MD), or Trach with subsequent MD (Trach+MD). Actual charges over a 3-year period associated with operative costs, hospital stay, imaging and sleep studies, clinic visits, and related emergency room visits were collected. Home tracheostomy care charges were estimated individually for each patient. Charges were compared using regression and appropriate statistical analyses. Forty-seven neonates were included in the study (MD, n = 26; Trach, n = 12; Trach+MD, n = 9). Trach group patients had 2.6-fold higher charges than the MD group despite no difference in length of hospital stay. This difference increased to 7.3-fold when including home trach care-related costs. Trach+MD group patients had longer hospital lengths of stay and higher operation room (OR) fees, but no increased total charges compared with the Trach only group. For patients with severe PRS, mandibular distraction provides significant cost savings over tracheostomy ($300,000 per patient over 3 years). Increased costs with tracheostomy come from greater hospital-related charges, more frequent airway procedures, a higher incidence of gastrostomy tube feeds, and home trach care costs. A careful examination of long-term outcomes will be critical as mandibular distraction continues to gain acceptance for treatment of PRS. © American Academy of Otolaryngology-Head and Neck Surgery Foundation 2014.

What to expect from dynamical modelling of galactic haloes - II. The spherical Jeans equation

The spherical Jeans equation (SJE) is widely used in dynamical modelling of the Milky Way (MW) halo potential. We use haloes and galaxies from the cosmological Millennium-II simulation and hydrodynamical APOSTLE (A Project of Simulations of The Local Environment) simulations to investigate the performance of the SJE in recovering the underlying mass profiles of MW mass haloes. The best-fitting halo mass and concentration parameters scatter by 25 per cent and 40 per cent around their input values, respectively, when dark matter particles are used as tracers. This scatter becomes as large as a factor of 3 when using star particles instead. This is significantly larger than the estimated statistical uncertainty associated with the use of the SJE. The existence of correlated phase-space structures that violate the steady-state assumption of the SJE as well as non-spherical geometries is the principal source of the scatter. Binary haloes show larger scatter because they are more aspherical in shape and have a more perturbed dynamical state. Our results confirm that the number of independent phase-space structures sets an intrinsic limiting precision on dynamical inferences based on the steady-state assumption. Modelling with a radius-independent velocity anisotropy, or using tracers within a limited outer radius, result in significantly larger scatter, but the ensemble-averaged measurement over the whole halo sample is approximately unbiased.

"He sees the development of children's concepts upon a background of sociology": Jean Piaget's honorary degree at Harvard University in 1936.

In the recent memory, Jean Piaget has been known as a cognitive developmental psychologist. But in 1936 when Harvard gave him his first honorary degree, he was recognized mainly as a sociologist. Why did Harvard honor him in 1936? Who knew his work well enough to nominate him? This article will address these questions by exploring archival documents from different sources. Evidence draws our attention to a broad social and intellectual endeavor in philanthropy, other social sciences, and especially industrial research that brought Piaget across the water. This article also attempts to interpret the circumstances of the nomination process inside and outside of Harvard University by using a theory of institutional design. It suggests that embodied in Harvard's honor of Piaget in 1936 was an idealistic act in social designing for a future society.

The Cosmic Ray Observatory Project (CROP) is a statewide education and research experiment involving Nebraska high school students, teachers, and college undergraduates in the study of extensive cosmic-ray air showers. A network of high school teams construct, install, and operate school-based detectors in coordination with University of Nebraska physics professors and graduate students. The detector system at each school is an array of scintillation counters recycled from the Chicago Air Shower Array in weather-proof enclosures on the school roof, with a GPS receiver providing a time stamp for cosmic-ray events. The detectors are connected to triggering electronics and a data-acquisition PC inside the building. Students share data via the Internet to search for time coincidences with other sites. CROP has enlisted 26 schools in its first 5 years of operation with the aim of expanding to the 314 high schools in the state over the next several years. The presenter also serves as the Task Leader for Education and Outreach for the Pierre Auger Cosmic Ray Observatory, and selected public outreach activities related to the experiment will be described.

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

We present first results from a trigger based on the discrete cosine transform (DCT) operating in new front-end boards with a Cyclone V E field-programmable gate array (FPGA) deployed in seven test surface detectors in the Pierre Auger Test Array. The patterns of the ADC traces generated by very inclined showers (arriving at 70° to 90° from the vertical) were obtained from the Auger database and from the CORSIKA simulation package supported by the Auger OffLine event reconstruction platform that gives predicted digitized signal profiles. Simulations for many values of the initial cosmic ray angle of arrival, the shower initialization depth in the atmosphere, the type of particle, and its initial energy gave a boundary on the DCT coefficients used for the online pattern recognition in the FPGA. Preliminary results validated the approach used. We recorded several showers triggered by the DCT for 120 Msamples/s and 160 Msamples/s.

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

Pongamia pinnata (L.) Pierre is one of the many plants with diverse medicinal properties where all its parts have been used as traditional medicine in the treatment and prevention of several kinds of ailments in many countries such as for treatment of piles, skin diseases, and wounds. This review discusses the current knowledge of traditional uses, phytochemistry, biological activities, and toxicity of this species in order to reveal its therapeutic and gaps requiring future research opportunities. This review is based on literature study on scientific journals and books from library and electronic sources such as ScienceDirect, PubMed, ACS, etc. Several different classes of flavonoid derivatives, such as flavones, flavans, and chalcones, and several types of compounds including terpenes, steroid, and fatty acids have been isolated from all parts of this plant. The pharmacological studies revealed that various types of preparations, extracts, and single compounds of this species exhibited a broad spectrum of biological activities such as antioxidant, antimicrobial, anti-inflammatory, and anti-diabetic activities. The results of several toxicity studies indicated that extracts and single compounds isolated from this species did not show any significant toxicity and did not cause abnormality on some rats' organs. Thus, this plant has a potential to be used as an effective therapeutic remedy due to its low toxicity towards mammalian cells. However, further study on chemical constituents and their mechanisms in exhibiting certain biological activities are needed to understand the full phytochemical profile and the complex pharmacological effects of this plant. In addition, further study on the toxicity of the other compounds isolated from this plant required to be assessed to ensure their eligibility to be used as sources of drugs. © 2013 Elsevier Ireland Ltd.

2015-03-30

In this study, we present the results of an analysis of the large angular scale distribution of the arrival directions of cosmic rays with energy above 4 EeV detected at the Pierre Auger Observatory including for the first time events with zenith angle between 60° and 80°. We perform two Rayleigh analyses, one in the right ascension and one in the azimuth angle distributions, that are sensitive to modulations in right ascension and declination, respectively. The largest departure from isotropy appears in themore » $$E\\gt 8$$ EeV energy bin, with an amplitude for the first harmonic in right ascension $$r_{1}^{\\alpha }=(4.4\\pm 1.0)\\times {{10}^{-2}}$$, that has a chance probability $$P(\\geqslant r_{1}^{\\alpha })=6.4\\times {{10}^{-5}}$$, reinforcing the hint previously reported with vertical events alone.« less

We report a study of the distributions of the depth of maximum, X max, of extensive air-shower profiles with energies above 10 17.8 eV as observed with the fluorescence telescopes of the Pierre Auger Observatory. The analysis method for selecting a data sample with minimal sampling bias is described in detail as well as the experimental cross-checks and systematic uncertainties. Furthermore, we discuss the detector acceptance and the resolution of the X max measurement and provide parametrizations thereof as a function of energy. Finally, the energy dependence of the mean and standard deviation of the X max distributions are comparedmore » to air-shower simulations for different nuclear primaries and interpreted in terms of the mean and variance of the logarithmic mass distribution at the top of the atmosphere.« less

STS-103 M.S. Steven Smith during TCDT activities

NASA Technical Reports Server (NTRS)

1999-01-01

STS-103 Mission Specialist Steven L. Smith gets ready to practice driving a small armored personnel carrier that is part of emergency egress training during Terminal Countdown Demonstration Test (TCDT) activities. The tracked vehicle could be used by the crew in the event of an emergency at the pad during which the crew must make a quick exit from the area. The TCDT also provides simulated countdown exercises and opportunities to inspect the mission payloads in the orbiter's payload bay. STS-103 is a 'call-up' mission due to the need to replace and repair portions of the Hubble Space Telescope. Although Hubble is operating normally and conducting its scientific observations, only three of its six gyroscopes are working properly. Four EVA's are planned to make the necessary repairs and replacements on the telescope. The other STS-103 crew members are Commander Curtis L. Brown Jr., Pilot Scott J. Kelly, and Mission Specialists John M. Grunsfeld (Ph.D.), C. Michael Foale (Ph.D.), (Ph.D.), and Claude Nicollier of Switzerland and Jean-Frangois Clervoy of France, who are with the European Space Agency. The mission is targeted for launch Dec. 6 at 2:37 a.m. EST.

World War I (1914-1918), however tragic, was nonetheless an "edifying school of nervous system experimental pathology" not only because of the various types of injuries, but also because their numbers were greater than any physician could have foreseen. The peripheral nervous system, the spine and the brain were all to benefit from the subsequent advances in clinical and anatomo-functional knowledge. Neurosurgeons took on nerve sutures, spinal injury exploration, and the localization and extraction of intracranial foreign bodies. Little by little, physical medicine and rehabilitation were established. A few of the most famous Parisian neurologists at the time-Jules and Augusta Dejerine, Pierre Marie, Joseph Babiński and Georges Guillain, who directed the military neurology centers-took up the physically and emotionally exhausting challenge of treating thousands of wounded soldiers. They not only cared for them, but also studied them scientifically, with the help of a small but devoted band of colleagues. The examples presented here reveal their courage and their efforts to make discoveries for which we remain grateful today. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Can telemetry data obviate the need for sleep studies in Pierre Robin Sequence?

PubMed

Aaronson, Nicole Leigh; Jabbour, Noel

2017-09-01

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

Social inequality, lifestyles and health - a non-linear canonical correlation analysis based on the approach of Pierre Bourdieu.

PubMed

Grosse Frie, Kirstin; Janssen, Christian

2009-01-01

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

Measurement of the cosmic ray spectrum above 4×10 18 eV using inclined events detected with the Pierre Auger Observatory

DOE PAGES

Aab, Alexander

2015-08-26

A measurement of the cosmic-ray spectrum for energies exceeding 4×10 18 eV is presented, which is based on the analysis of showers with zenith angles greater than 60° detected with the Pierre Auger Observatory between 1 January 2004 and 31 December 2013. The measured spectrum confirms a flux suppression at the highest energies. Above 5.3×10 18 eV, the ``ankle'', the flux can be described by a power law E –γ with index γ=2.70 ± 0.02 (stat) ± 0.1 (sys) followed by a smooth suppression region. For the energy (E s) at which the spectral flux has fallen to one-half ofmore » its extrapolated value in the absence of suppression, we find E s=(5.12±0.25 (stat) +1.0 –1.2 (sys))×10 19 eV.« less

A thorough search for large-scale anisotropies in the distribution of arrival directions of cosmic rays detected above 1018 eV at the Pierre Auger Observatory is reported. For the first time, these large-scale anisotropy searches are performed as a function of both the right ascension and the declination and expressed in terms of dipole and quadrupole moments. Within the systematic uncertainties, no significant deviation from isotropy is revealed. Upper limits on dipole and quadrupole amplitudes are derived under the hypothesis that any cosmic ray anisotropy is dominated by such moments in this energy range. These upper limits provide constraints on the production of cosmic rays above 1018 eV, since they allow us to challenge an origin from stationary galactic sources densely distributed in the galactic disk and emitting predominantly light particles in all directions.

"Mathematics made no contribution to the public weal": why Jean Fernel (1497-1558) became a physician.

PubMed

Henry, John

2011-01-01

This paper offers a caution that emphasis upon the importance of mathematics in recent historiography is in danger of obscuring the historical fact that, for the most part, mathematics was not seen as important in the pre-modern period. The paper proceeds by following a single case study, and in so doing offers the first account of the mathematical writings of Jean Fernel (1497-1558), better known as a leading medical innovator of the 16th century. After establishing Fernel's early commitment to mathematics, and attempt to forge a career as a cosmographer, it goes on to explain his abandonment of mathematics for a career in medicine. The 'mathematization of the world picture' is usually explained in terms of the perceived usefulness of mathematics, but Fernel's case shows that for many pre-modern thinkers, mathematics was not regarded as a useful pursuit. The paper should serve as a reminder, therefore, that the take-up of mathematics by natural philosophers was by no means inevitable, but had to be carefully managed by early modern mathematical practitioners. The case of Fernel indicates that perhaps he was not the only would-be mathematical practitioner to abandon mathematics in favor of a calling that was more appreciated by contemporaries.

Jean-Martin Charcot and art: relationship of the "founder of neurology" with various aspects of art.

PubMed

Bogousslavsky, Julien; Boller, François

2013-01-01

Jean-Martin Charcot (1825-1893), the "father of neurology" in France and much beyond, was also the man who established academic psychiatry in Paris, differentiating it from clinical alienism. In his teaching, he used artistic representations from previous centuries to illustrate the historical developments of hysteria, mainly with the help of his pupil Paul Richer. Charcot liked to draw portraits (in particular, sketches of colleagues during boring faculty meetings and students' examinations), caricatures of himself and others, church sculptures, landscapes, soldiers, etc. He also used this skill in his clinical and scientific work; he drew histological or anatomic specimens, as well as patients' features and demeanor. His most daring artistic experiments were drawing under the influence of hashish. Charcot's tastes in art were conservative; he displayed no affinity for the avant-gardes of his time, including impressionism, or for contemporary musicians, such as César Franck or Hector Berlioz. Léon Daudet, son of Charcot's former friend and famous writer Alphonse Daudet, described Charcot's home as a pseudo-gothic kitsch accumulation of heteroclite pieces of furniture and materials. However, as Henry Meige wrote a few years after his mentor's death, Charcot the artist remains "inseparable from Charcot the physician." © 2013 Elsevier B.V. All rights reserved.

Multi-resolution anisotropy studies of ultrahigh-energy cosmic rays detected at the Pierre Auger Observatory

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

Close Range Uav Accurate Recording and Modeling of St-Pierre Neo-Romanesque Church in Strasbourg (france)

Murtiyoso, A.; Grussenmeyer, P.; Freville, T.

2017-02-01

Close-range photogrammetry is an image-based technique which has often been used for the 3D documentation of heritage objects. Recently, advances in the field of image processing and UAVs (Unmanned Aerial Vehicles) have resulted in a renewed interest in this technique. However, commercially ready-to-use UAVs are often equipped with smaller sensors in order to minimize payload and the quality of the documentation is still an issue. In this research, two commercial UAVs (the Sensefly Albris and DJI Phantom 3 Professional) were setup to record the 19th century St-Pierre-le-Jeune church in Strasbourg, France. Several software solutions (commercial and open source) were used to compare both UAVs' images in terms of calibration, accuracy of external orientation, as well as dense matching. Results show some instability in regards to the calibration of Phantom 3, while the Albris had issues regarding its aerotriangulation results. Despite these shortcomings, both UAVs succeeded in producing dense point clouds of up to a few centimeters in accuracy, which is largely sufficient for the purposes of a city 3D GIS (Geographical Information System). The acquisition of close range images using UAVs also provides greater LoD flexibility in processing. These advantages over other methods such as the TLS (Terrestrial Laser Scanning) or terrestrial close range photogrammetry can be exploited in order for these techniques to complement each other.

2016-04-01

The Pierre Auger Observatory is the largest extensive air shower detector, covering 3000 km2 in Argentina. The Observatory makes available, for educational and outreach purposes, 1% of its cosmic ray data set, corresponding after 10 years of running to more than 35 000 cosmic ray events. Several different proposals of educational activities have been developed within the collaboration and are available. We will focus on the activity guide we developed with the aim of exploring the rich education and outreach potential of cosmic rays with Portuguese high school students. In this guide we use the Auger public data set as a starting point to introduce open questions on the origin, nature and spectrum of high energy cosmic rays. To address them, the students learn about the air-shower cascade development, data reconstruction and its statistical analysis. The guide has been used both in the context of student summer internships at research labs and directly in schools, under the supervision of trained teachers and in close collaboration with Auger researchers. It is now available in Portuguese, English and Spanish.

Piezosurgery: A new and safe technique for distraction osteogenesis in Pierre Robin sequence review of the literature and case report

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

The Pierre Auger Observatory is exploring the potential of the radio detection technique to study extensive air showers induced by ultra-high energy cosmic rays. The Auger Engineering Radio Array (AERA) addresses both technological and scientific aspects of the radio technique. A first phase of AERA has been operating since September 2010 with detector stations observing radio signals at frequencies between 30 and 80 MHz. In this paper we present comparative studies to identify and optimize the antenna design for the final configuration of AERA consisting of 160 individual radio detector stations. The transient nature of the air shower signal requires a detailed description of the antenna sensor. As the ultra-wideband reception of pulses is not widely discussed in antenna literature, we review the relevant antenna characteristics and enhance theoretical considerations towards the impulse response of antennas including polarization effects and multiple signal reflections. On the basis of the vector effective length we study the transient response characteristics of three candidate antennas in the time domain. Observing the variation of the continuous galactic background intensity we rank the antennas with respect to the noise level added to the galactic signal.

These remotely sensed, geographically referenced elevation measurements of Lidar-derived first surface (FS) and bare earth (BE) topography were produced as a collaborative effort between the U.S. Geological Survey (USGS), Florida Integrated Science Center (FISC), St. Petersburg, FL; the National Park Service (NPS), Gulf Coast Network, Lafayette, LA; and the National Aeronautics and Space Administration (NASA), Wallops Flight Facility, VA. This project provides highly detailed and accurate datasets of the Jean Lafitte National Historical Park and Preserve in Louisiana, acquired on September 22, 2006. The datasets are made available for use as a management tool to research scientists and natural resource managers. An innovative airborne Lidar instrument originally developed at the NASA Wallops Flight Facility, and known as the Experimental Advanced Airborne Research Lidar (EAARL), was used during data acquisition. The EAARL system is a raster-scanning, waveform-resolving, green-wavelength (532-nanometer) Lidar designed to map near-shore bathymetry, topography, and vegetation structure simultaneously. The EAARL sensor suite includes the raster-scanning, water-penetrating full-waveform adaptive Lidar, a down-looking red-green-blue (RGB) digital camera, a high-resolution multi-spectral color infrared (CIR) camera, two precision dual-frequency kinematic carrier-phase GPS receivers, and an integrated miniature digital inertial measurement unit, which provide for submeter georeferencing of each laser sample. The nominal EAARL platform is a twin-engine Cessna 310 aircraft, but the instrument may be deployed on a range of light aircraft. A single pilot, a Lidar operator, and a data analyst constitute the crew for most survey operations. This sensor has the potential to make significant contributions in measuring sub-aerial and submarine coastal topography within cross-environmental surveys. Elevation measurements were collected over the survey area using the EAARL system

Traditional vegetation maps capture the horizontal distribution of various vegetation properties, for example, type, species and age/senescence, across a landscape. Ecologists have long known, however, that many important forest properties, for example, interior microclimate, carbon capacity, biomass and habitat suitability, are also dependent on the vertical arrangement of branches and leaves within tree canopies. The objective of this study was to use a digital elevation model (DEM) along with tree canopy-structure metrics derived from a lidar survey conducted using the Experimental Advanced Airborne Research Lidar (EAARL) to capture a three-dimensional view of vegetation communities in the Barataria Preserve unit of Jean Lafitte National Historical Park and Preserve, Louisiana. The EAARL instrument is a raster-scanning, full waveform-resolving, small-footprint, green-wavelength (532-nanometer) lidar system designed to map coastal bathymetry, topography and vegetation structure simultaneously. An unsupervised clustering procedure was then applied to the 3-dimensional-based metrics and DEM to produce a vegetation map based on the vertical structure of the park's vegetation, which includes a flotant marsh, scrub-shrub wetland, bottomland hardwood forest, and baldcypress-tupelo swamp forest. This study was completed in collaboration with the National Park Service Inventory and Monitoring Program's Gulf Coast Network. The methods presented herein are intended to be used as part of a cost-effective monitoring tool to capture change in park resources.

Energy Estimation of Cosmic Rays with the Engineering Radio Array of the Pierre Auger Observatory

The Auger Engineering Radio Array (AERA) is part of the Pierre Auger Observatory and is used to detect the radio emission of cosmic-ray air showers. These observations are compared to the data of the surface detector stations of the Observatory, which provide well-calibrated information on the cosmic-ray energies and arrival directions. The response of the radio stations in the 30 to 80MHz regime has been thoroughly calibrated to enable the reconstruction of the incoming electric field. For the latter, the energy density is determined from the radio pulses at each observer position and is interpolated using a two dimensional functionmore » that takes into account signal asymmetries due to interference between the geomagnetic and charge excess emission components. We found that the spatial integral over the signal distribution gives a direct measurement of the energy transferred from the primary cosmic ray into radio emission in the AERA frequency range. We measure 15.8MeV of radiation energy for a 1 EeV air shower arriving perpendicularly to the geomagnetic field. This radiation energy – corrected for geometrical effects – is used as a cosmic-ray energy estimator. Performing an absolute energy calibration against the surface-detector information, we observe that this radio-energy estimator scales quadratically with the cosmic-ray energy as expected for coherent emission. Finally we find an energy resolution of the radio reconstruction of 22% for the data set and 17% for a high-quality subset containing only events with at least five radio stations with signal.« less

The Pierre Auger Observatory is making significant contributions towards understanding the nature and origin of ultra-high energy cosmic rays. One of its main challenges is the monitoring of the atmosphere, both in terms of its state variables and its optical properties. The aim of this work is to analyse aerosol optical depth τa(z) values measured from 2004 to 2012 at the observatory, which is located in a remote and relatively unstudied area of Pampa Amarilla, Argentina. The aerosol optical depth is in average quite low - annual mean τa(3.5 km) ∼ 0.04 - and shows a seasonal trend with a winter minimum - τa(3.5 km) ∼ 0.03 -, and a summer maximum - τa(3.5 km) ∼ 0.06 -, and an unexpected increase from August to September - τa(3.5 km) ∼ 0.055. We computed backward trajectories for the years 2005 to 2012 to interpret the air mass origin. Winter nights with low aerosol concentrations show air masses originating from the Pacific Ocean. Average concentrations are affected by continental sources (wind-blown dust and urban pollution), whilst the peak observed in September and October could be linked to biomass burning in the northern part of Argentina or air pollution coming from surrounding urban areas.

Mutations in the coding sequence of SOX9 cause campomelic dysplasia (CD), a disorder of skeletal development associated with 46,XY disorders of sex development (DSDs). Translocations, deletions and duplications within a ~2 Mb region upstream of SOX9 can recapitulate the CD-DSD phenotype fully or partially, suggesting the existence of an unusually large cis-regulatory control region. Pierre Robin sequence (PRS) is a craniofacial disorder that is frequently an endophenotype of CD and a locus for isolated PRS at ~1.2-1.5 Mb upstream of SOX9 has been previously reported. The craniofacial regulatory potential within this locus, and within the greater genomic domain surrounding SOX9, remains poorly defined. We report two novel deletions upstream of SOX9 in families with PRS, allowing refinement of the regions harbouring candidate craniofacial regulatory elements. In parallel, ChIP-Seq for p300 binding sites in mouse craniofacial tissue led to the identification of several novel craniofacial enhancers at the SOX9 locus, which were validated in transgenic reporter mice and zebrafish. Notably, some of the functionally validated elements fall within the PRS deletions. These studies suggest that multiple non-coding elements contribute to the craniofacial regulation of SOX9 expression, and that their disruption results in PRS. PMID:24934569

Geophysical surveys and archaeological insights at Fort Pierre Chouteau, a frontier trading post on the Middle Missouri

NASA Astrophysics Data System (ADS)

Patton, Margaret Maurine

Fort Pierre Chouteau in present day South Dakota was the most important fur trading post of the American Fur Company in the 1830s, serving as a regional hub for the fur trade. The Fort was sold to the U.S. Military in 1855 for use as a base in the Sioux Wars but was abandoned in 1856. Geophysical surveys and previous excavations indicate evidence of both occupations. Geophysics is an important tool for determining the extent of archaeological sites, yet the relationships between geophysical anomalies and excavation features may not be readily evident. Initial geophysical surveys (Kvamme 2007) were completed to determine the extent of the fur trading Fort, and additional surveys in August 2012 used magnetometry and electrical resistance to determine if evidence of military structures exists outside of the Fort. This study examines connections between excavation features and geophysical anomalies in order to better interpret anomalies inside the Fort palisade. The palisade builder's trench, adobe pavement, post holes, and unknown structures are characterized through the analysis of the excavations and anomalies. The location of one of the military structures outside of the palisade is also identified. As many sites have histories of excavations prior to any geophysical surveys, combining the two sets of information is important in order to more fully understand site layout and the archaeological causes of geophysical anomalies.

Stratigraphy and Geochemistry of a Fond St. Jean Cinder Cone, Dominica

Current geologic maps of Dominica generally classify the south-eastern portion of the island surrounding the Foundland stratovolcano as "mafic breccias and thin lava flows of Foundland center" (Smith et al. 2013). A detailed survey of the stratigraphy of a road cut at Fond St. Jean provides evidence for a mafic cinder cone on the flanks of Foundland. The 39 m thick stratigraphic sequence, dipping 60˚ north, includes a basal unit of scoria overlain by a meter of basaltic breccia and repeating layers of massive and rubbly flows, which range from 1 to 10 m in thickness. These flows transition into an additional, 2 m thick scoria deposit capped by a meter of massive basalt, which sits beneath another 3-4 m scoria deposit. Another layer of massive flow then transitions to three units of alternating air fall and ash lenses. Air fall units are 0.5 m in thickness but pinch and swell regularly, and ash lenses are roughly 10 cm thick. All units contain plagioclase + olivine + clinopyroxene + orthopyroxene + titanomagnetite. Though the phase assemblage is consistent between basaltic units, different crystal morphologies serve to define individual massive flows. Variations in the texture of materials deposited by the cinder cone provides evidence for cyclic explosive and effusive episodes. Massive samples at the bottom of the stratigraphic section contain abundant, large olivine and tabular, elongate plagioclase. Plagioclase compositions between individual stratigraphic units span a similar range in composition. Massive flows throughout the column contain similar, weakly zoned plagioclase cores (An84-94) with 10-30 µm sodic rims (An58-78; most rims are 68). Plagioclase microlites (long axes ≤100µm) span a wide range of compositions (An50-90). Three different air fall units contain plagioclase rims ranging in composition from An58-86 and cores ranging from An84-92, with the exception of a single core that has a composition of An61. Olivine in most units ranges in

Joyce After Flaubert: the cuckold as imperfect physician, the writer as physiologist.

PubMed

Bénéjam, Valérie

2008-01-01

Although Joyce was not as familiar with the practice and theory of medicine as was Gustave Flaubert, this article argues that, through Flaubert's legacy, Joyce's writing was influenced by the French school of medical thought. Several aspects of Flaubert's style and narration-what has been dubbed his "medical realism"-were taken up by Joyce: the artist's impersonal perspective, the precision of descriptions, and the materialist attack against Romanticism, as well as the irony built into the narrative voice through free indirect discourse. While the cuckold in Madame Bovary is an incompetent surgeon serving as foil to the precise description of sentiments offered by the narrator, Joyce's cuckold in Ulysses is an amateur physiologist, both perspicacious and sympathetic to human suffering. Bloom's interest in internal bodily processes opens up new dimensions for a modernist aesthetics as he relates physiology and psychology, in accordance with the theories of Xavier Bichat, Etienne Bonnot de Condillac, and Pierre Jean Georges Cabanis. In keeping with such focus, Joyce's physiological version of stream-of-consciousness stems from Flaubert's clinical description of characters, but he directs matters even further inward.

Recent Ultra High Energy neutrino bounds and multimessenger observations with the Pierre Auger Observatory

NASA Astrophysics Data System (ADS)

Zas, Enrique

2018-01-01

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

The origins, early development and status of Bourdieu's concept of 'cultural capital'.

PubMed

Robbins, Derek

2005-03-01

The paper examines the context of the first introduction of the concept of 'cultural capital' in the sociology of education analyses undertaken in the early 1960s and published by Bourdieu in collaboration with Jean-Claude Passeron in 'Les etudiants et leurs etudes' (1964a) and Les Heritiers (1964b). It first considers the cultural contexts within which Bourdieu's thinking about culture originated--both in relation to his social origins and in relation to his intellectual training. It then examines the extent to which Bourdieu's early anthropological research in Algeria was influenced by his knowledge of American acculturation theory. It concludes that Bourdieu sought to use acculturation theory in a distinctive way--one which he articulated more confidently as he explored the relationship between agency and structural explanation in the late 1960s and early 1970s. The specific educational researches which stimulated the articulation of the concept of 'linguistic' or 'cultural' capital belonged to the period in which Bourdieu was only just beginning to refine his post-structuralist philosophy of social scientific explanation. To use these concepts now involves deploying them reflexively in accordance with Bourdieu's later thinking rather than at face value as they were first developed during the period in which he and Passeron were 'apprentice' researchers.

Spatio-temporal regulation of connexin43 phosphorylation and gap junction dynamics.

PubMed

Solan, Joell L; Lampe, Paul D

2018-01-01

Gap junctions are specialized membrane domains containing tens to thousands of intercellular channels. These channels permit exchange of small molecules (<1000Da) including ions, amino acids, nucleotides, metabolites and secondary messengers (e.g., calcium, glucose, cAMP, cGMP, IP 3 ) between cells. The common reductionist view of these structures is that they are composed entirely of integral membrane proteins encoded by the 21 member connexin human gene family. However, it is clear that the normal physiological function of this structure requires interaction and regulation by a variety of proteins, especially kinases. Phosphorylation is capable of directly modulating connexin channel function but the most dramatic effects on gap junction activity occur via the organization of the gap junction structures themselves. This is a direct result of the short half-life of the primary gap junction protein, connexin, which requires them to be constantly assembled, remodeled and turned over. The biological consequences of this remodeling are well illustrated during cardiac ischemia, a process wherein gap junctions are disassembled and remodeled resulting in arrhythmia and ultimately heart failure.

Defining the factors that affect solute permeation of gap junction channels.

Valiunas, Virginijus; Cohen, Ira S; Brink, Peter R

2018-01-01

This review focuses on the biophysical properties and structure of the pore and vestibule of homotypic gap junction channels as they relate to channel permeability and selectivity. Gap junction channels are unique in their sole role to connect the cytoplasm of two adjacent cells. In general, these channels are considered to be poorly selective, possess open probabilities approximating unity, and exhibit mean open times ranging from milliseconds to seconds. These properties suggest that such channels can function as delivery pathways from cell to cell for solutes that are significantly larger than monovalent ions. We have taken quantitative data from published works concerning unitary conductance, ion flux, and permeability for homotypic connexin 43 (Cx43), Cx40, Cx26, Cx50, and Cx37, and performed a comparative analysis of conductance and/or ion/solute flux versus diffusion coefficient. The analysis of monovalent cation flux portrays the pore as equivalent to an aqueous space where hydrogen bonding and weak interactions with binding sites dominate. For larger solutes, size, shape and charge are also significant components in determining the permeation rate.

The Surface Detector of the Pierre Auger Observatory is sensitive to neutrinos of all flavours above 0.1 EeV. These interact through charged and neutral currents in the atmosphere giving rise to extensive air showers. When interacting deeply in the atmosphere at nearly horizontal incidence, neutrinos can be distinguished from regular hadronic cosmic rays by the broad time structure of their shower signals in the water-Cherenkov detectors. In this paper we present for the first time an analysis based on down-going neutrinos. We describe the search procedure, the possible sources of background, the method to compute the exposure and the associated systematic uncertainties. No candidate neutrinos have been found in data collected from 1 January 2004 to 31 May 2010. Assuming an E^-2 differential energy spectrum the limit on the single flavour neutrino is (E^2 * dN/dE) < 1.74x10^-7 GeV cm^-2 s^-1 sr^-1 at 90% C.L. in the energy range 1x10^17 eV < E < 1x10^20 eV.

An in-situ calibration of a logarithmic periodic dipole antenna with a frequency coverage of 30 MHz to 80 MHz is performed. Such antennas are part of a radio station system used for detection of cosmic ray induced air showers at the Engineering Radio Array of the Pierre Auger Observatory, the so-called Auger Engineering Radio Array (AERA). The directional and frequency characteristics of the broadband antenna are investigated using a remotely piloted aircraft (RPA) carrying a small transmitting antenna. The antenna sensitivity is described by the vector effective length relating the measured voltage with the electric-field components perpendicular to the incoming signal direction. The horizontal and meridional components are determined with an overall uncertainty ofmore » $$7.4^{+0.9}_{-0.3} %$$ and $$10.3^{+2.8}_{-1.7} %$$ respectively. The measurement is used to correct a simulated response of the frequency and directional response of the antenna. In addition, the influence of the ground conductivity and permitivity on the antenna response is simulated. Both have a negligible influence given the ground conditions measured at the detector site. The overall uncertainties of the vector effective length components result in an uncertainty of $$9.4^{+1.5}_{-1.6} %$$ in the square root of the energy fluence for incoming signal directions with zenith angles smaller than 60°.« less
