    Jean-Nicolas Trusson is well known in the history of Parisian pharmacy. Born in 1744 in Euville, in the vicinity of Commercy, in Lorraine, he was in near relations by his mother with Joseph Bataille, also well known and whose half-length portrait is exhibited in the "Salle des Actes" of the Faculty of Pharmacy in Paris. It seems that the extraction of Bataille is unknown. Our work indicates that he was born in october 1816 in Pagny-sur-Meuse, some kilometres from Euville towards Toul. Trusson was the successor of Bataille and he remained in his pharmacy until 1809 where his own successor was Nicolas Denis Moutillard. Moutillard's father was Joseph Moutillard, an apothecary of Commercy, whose mother was Jeanne Trusson, who was the first cousin of Jean-Nicolas Trusson's father. Then, Théodore Huraut, Moutillard's successor in Paris, was also born in Commercy, in year 1813. He studied pharmacy in Bar-le-Duc, then in Paris with Moutillard and at the school of pharmacy. Taking his place between 1840 and 1844, he became a member of the "Société d'émulation pour les sciences pharmaceutiques" and of the "Société de pharmacie de Paris". Beeing the author of more than twenty papers devoted to practical community pharmacy, Huraut died in Paris in 1855. PMID:21032928

  3. Understanding of Jeans Rule

    NASA Astrophysics Data System (ADS)

    Gao, C. Y.

    2002-11-01

    Jeans empirical rule has always been used in planetary physics. From the static equation of atmosphere, the equation of state for ideal gases, the law of gravitation and the law of Maxwell distribution, Jeans empirical rule can be derived. Therefore, it seems that Jeans empirical rule should be called Jeans rule. It can be formulated in three forms: in terms of velocity, height, or energy. These three formulations are completely equivalent. According to concrete situation, any one of these forms can be taken freely and used as a criterion, which define whether the atmospheric composition of a given species of particles at the planet surface will exist "forever" or not. The factor in the energy formulation will be neither too large nor too small. According to statistical theory, taking the viewpoint of energy, Jeans rule can be explained more easily. The condition satisfying Jeans rule is only the necessary condition for a given species of partials to be major atmospheric composition of the planets which have dense atmosphere. Jeans rule is not only applicable for the planets and satellites in the solar system, but also suitable for the asteroids, meteoroids and outer solar system objects, such as Centaurs and Kuiper belt objects. The application scope of Jeans rule can be expressed with nomogram as well as defined by equation or by figures. Having been widely used for a long time, it still has a general practical significance in detecting age of planets in the solar system nowadays, especially for the research of outer solar system objects.

  7. Applicability of Jeans criterion.

    Čadež, V.

    1995-03-01

    The applicability of the gravitational instability criterion is discussed for some typical configurations. It is shown that the small perturbation method has to be applied only locally, the reason being that the medium of a self-gravitating cloud cannot be considered as homogeneous throughout the whole space. Consequently, there is an upper limit to the geometrical size of a perturbation, defined by the typical inhomogeneity scale length L. On the other hand, according to Jeans criterion, the gravitational instability sets in for perturbations having their linear dimensions larger than some critical length LJ, the Jeans length. It is therefore of importance to estimate the value of the ratio L/LJ in order to be sure that the local analysis conclusions are meaningful.

    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.

  9. Anxiety and surplus in nursing practice: lessons from Lacan and Bataille.

    PubMed

    Evans, Alicia M; Glass, Nel; Traynor, Michael

    2014-07-01

    It is well established, following Menzies' work, that nursing practice produces considerable anxiety. Like Menzies, we bring a psychoanalytic perspective to a theorization of anxiety in nursing and do so in order to consider nursing practice in the light of psychoanalytic theory, although from a Lacanian perspective. We also draw on Bataille's notion of 'surplus'. These concepts provide the theoretical framework for a study investigating how some clinical nurses are able to remain in clinical practice rather than leave the profession or seek work at a distance from the bedside. We conducted focus groups and present here an analysis of two fragments of nurses' speech. We found the nurses responded from one of two positions. In the first position, the nurses focus on doctors, complain about the surplus afforded them, and call for it to be eliminated. In this way, the nursing group is similar to other groups, considered by Bataille, who also attempt to get rid of a surplus. However, in the second position, the nurses stay with the surplus, tolerating it as they nurse the patient. This latter position is one where the nurse practises with a focus on the patient rather than being distracted by their dispute over the doctor's privilege. The importance of this paper is in its illustration of two distinct positions from which the nurse can practise: one that is not optimal because the nurse is distracted and the other that is more focused on practice, and thus the nurse is in a position to provide the best care possible to patients.

  10. Jean Laplanche's Masochism.

    PubMed

    Ray, Nicholas

    2015-10-01

    This essay examines the theme of masochism in the metapsychological work of French psychoanalyst Jean Laplanche. One of the most distinctive aspects of Laplanche's work as a whole is its recursiveness: it advances by repeatedly retraversing the same themes and rereading the same Freudian texts, often after intervals of years and each time from a deepened critical perspective. The approach taken in this essay is therefore diachronic. That is, rather than seeking to present a reduced summation of Laplanche's position on masochism, it tracks the recursive evolution of his thinking about masochism, from the 1960s through to the development of his celebrated "general theory of seduction." The essay locates each of Laplanche's key interventions on masochism within the broader frameworks of his theoretical enterprise, and positions masochism as a point of orientation for understanding a number of the essential claims of his metapsychology, particularly the relationships among fantasy, pain and the drives; the economic dimensions of human desire; and the intersubjective origins of psychosexuality. Finally, the essay suggests that masochism might have a particular pertinence to psychoanalytic thinking as Laplanche conceives and practices it: that is, as a pains-taking labor whose very stimulus is the "wound" of the Freudian breakthrough.

  11. Interview With Jean Laplanche.

    PubMed

    Laplanche, Jean; Danon, Gisèle; Lauru, Didier

    2015-10-01

    The starting point for this interview with Jean Laplanche is a question regarding the place of infantile sexuality within psychoanalysis today. Laplanche begins by underscoring the audaciousness of Freud's characterization of infantile sexuality and the significance of the expansion of the field of "the sexual" that this characterization entails. He goes on to outline his celebrated "general theory of seduction." In doing so he explains key terms associated with it, such as the "enigmatic message" and the "fundamental anthropological situation," and clarifies how the theory seeks to account for sexuality in the expanded sense. In particular, Laplanche stresses the intersubjective origins of "drive" sexuality in infancy, its chaotic evolution, its unique economic mode of functioning, and its subsequent conflict with innate "instinctual" sexual impulses that surge forth at puberty. He also positions the general theory of seduction in relation to the important advances made by attachment theory in the field of the adult-child relationship. Throughout the interview, the discussion touches on social contexts, and at points Laplanche outlines positions on topical concerns connected to education, media, and the law, and the importance of rethinking certain psychoanalytic paradigms in an age of new family structures that do not correspond to the nuclear unit.

    Nineteenth century's physics was primarily a molecular physics in the style of Laplace. Maxwell had been guided by Laplace's breathtaking nebular hypothesis and its consequences for Saturn. Somewhat later Van der Waals drew upon his analysis of capillarity. The many textbooks of Biot perpetuated the molecularism involved in all this. Jean Perrin, then, proposed a charmingly simple proof for the well-foundedness of the molecular theory (1908).

    2009-01-15

    Jeans instability in a homogeneous cold quantum dusty plasma in the presence of the ambient magnetic field and the quantum effect arising through the Bohm potential has been examined using the quantum magnetohydrodynamic model. It is found that the Jeans instability is significantly reduced by the presence of the dust-lower-hybrid wave and the ion quantum effect. The minimum wavenumber for Jeans stability depends clearly on ion quantum effect and the dust-lower-hybrid frequency also.

  15. Jeans' criterion in nonextensive statistical mechanics

    NASA Astrophysics Data System (ADS)

    Jiulin, Du

    2004-04-01

    The Jeans' gravitational instability in nonextensive statistical mechanics is studied and a general form of the generalized Jeans' criterion is obtained that is related to the q-function cq=∑ipiq. In this approach, the nonextensive model of classical ideal gas is applied to the Jeans' problem instead of the ordinary one in extensive statistical mechanics and the generalized critical wavelength to describe the gravitational instability is deduced. This nonextensive modification of the Jeans' criterion leads to a new critical length that depends not only on the nonextensive parameter q but also on the dimension D and the total particle numbers N of the system. When q-->1-, the Jeans' length is perfectly recovered. We also give the nonextensive parameter q a physical interpretation that q=1 represents an isothermal process of the gas, corresponding to the state of complete mixing, but 0

  16. Some remarks on the jeans rule

    NASA Astrophysics Data System (ADS)

    Gao, Chong-yi

    From the basic laws of physics one can deduce the Jeans empirical rule, which should preferably be called the Jeans rule. Its representations in velocity, height and energy are completely equivalent and may be arbitrarily chosen. This rule is most easily interpreted in terms of energy. The Jeans rule merely provides a necessary condition for the particles to be the main atmospheric constituent of a planet or satellite with a dense atmosphere. Its range of applicability can be expressed by equations or figures, or by a nomogram. It is applicable to planets, satellites, asteroids and meteoric bodies in the solar system, as well as to some objects in the outer solar system, such as the objects in the Kuiper belt and the Centaurs. This rule still possesses a general and realistic significance even at present day.

    2014-09-15

    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 Fernel (1497-1558) embodied the humanist spirit of the Renaissance. He studied philosophy (especially Aristotle), astrology, arithmetic, mathematics and Latin literature before devoting his life to medicine. He conducted a comprehensive synthesis of the medical system of Galen, and invented the terms "physiology" and "pathology". His taste for teaching, his extensive clinical practice, his benevolent attitude to the sick, and his consideration for individuals and for human nature all contribute to Jean Fernel's image as a humanist. He was the most famous physician of his time, although his work relying on philosophy and galenic dogmatism eventually became obsolete. Forgotten for half a millennium, this distant precursor of holistic medicine is worthy of renewed interest. PMID:22530525

  4. Jeans criterion in a turbulent medium

    According to the classical Jeans analysis, all the molecular clouds of mass larger than a few 100 M(solar), size larger than about 1pc and kinetic temperature Tk less than 30K are gravitationally unstable. We have shown that in clouds supported by internal supersonic motions, local gravitational instabilities may appear within molecular clouds which are globally stable. The argument is threefold: (1) when the turbulent kinetic energy is included into the internal energy term, the virial equilibrium condition shows that molecular clouds such as those observed, which are gravitationally unstable according to the Jeans criterion, are indeed globally stable if supported by a turbulent velocity field of power spectrum steeper than 3; (2) 2D compressible hydrodynamical simulations show that a supersonic turbulent velocity field generates a turbulent pressure within clouds, the gradients of which stabilize the unstable scales (i.e., the largest scales and the cloud itself) against gravitational collapse; (3) an analysis similar to the Jeans approach but including the turbulent pressure gradient term, gives basically the same results as those given in (1). Clouds of mean density lower than a critical value are found to be stable even though more massive than their Jeans mass. In clouds of mean density larger than that critical value, the gravitational instability appears only over a range of scales smaller than the cloud size, the largest scales being stable. In practice, the observed mean densities are lower than this critical value: the observation of a small number of cores and stars of a few solar masses embedded in clouds of several hundred solar masses can only be understood in terms of small scale density fluctuations of large amplitude generated by the supersonic turbulence which would occasionally overtake the limit of gravitational stability.

We also draw attention to the most interesting personality of Houzeau, and to his social engagement that went much beyond his work as a scientist.

    From a survey of 729 cores based on JCMT/SCUBA data, we present an analysis of 17 candidate starless cores with masses that exceed their stable Jeans masses. We re-examine the classification of these super-Jeans cores using Spitzer maps and find that 3 are re-classified as protostellar, 11 have ambiguous emission near the core positions, and 3 appear to be genuinely starless. We suggest that the 3 starless and 11 undetermined super-Jeans cores represent excellent targets for future observational and computational study to understand the evolution of dense cores and the process of star formation.

  2. Jean-Louis Vignes: California's forgotten winemaker.

    PubMed

    Macconnell, Scott

    2011-01-01

    This article represents a first step in the process of restoring the legacy of pioneer California winemaker Jean-Louis Vignes (1780–1862). Vignes was a native of France who established and operated a commercial winery (El Aliso) in Los Angeles for 22 years (1833–1855). The article includes the first known photograph of Vignes discovered by the author. While prominent twentieth-century American wine historians have acknowledged Vignes, the author emphasizes a key distinction made by French historian Leonce Jore. Vignes left France to go to the Sandwich Islands as part of a commercial enterprise that traveled with Catholic missionaries (Picpus Fathers). Only after five years of frustration did Vignes move to Los Angeles and establish a winery. The author uses the remembrances of well-known nineteenth-century commentator William Heath Davis [Seventy-Five Years in California (San Francisco, 1929)] to give some personal insights into Vignes as a winemaker. Davis visited him at El Aliso three times as a young man and lived long enough (1909) to validate Vignes’s vision for the potential of winemaking in California. The article also includes the first known full citation for Vignes’s gravesite at Evergreen Cemetery in Los Angeles. PMID:21591314

    We perform a linear dynamical stability analysis of a general hydrodynamic model of chemotactic aggregation [P.H. Chavanis, C. Sire, Physica A 384 (2007) 199]. Specifically, we study the stability of an infinite and homogeneous distribution of cells against “chemotactic collapse”. We discuss the analogy between the chemotactic collapse of biological populations and the gravitational collapse (Jeans instability) of self-gravitating systems. Our hydrodynamic model involves a pressure force which can take into account several effects like anomalous diffusion or the fact that the organisms cannot interpenetrate. We also take into account the degradation of the chemical which leads to a shielding of the interaction like for a Yukawa potential. Finally, our hydrodynamic model involves a friction force which quantifies the importance of inertial effects. In the strong friction limit, we obtain a generalized Keller-Segel model similar to the generalized Smoluchowski-Poisson system describing self-gravitating Langevin particles. For small frictions, we obtain a hydrodynamic model of chemotaxis similar to the Euler-Poisson system describing a self-gravitating barotropic gas. We show that an infinite and homogeneous distribution of cells is unstable against chemotactic collapse when the “velocity of sound” in the medium is smaller than a critical value. We study in detail the linear development of the instability and determine the range of unstable wavelengths, the growth rate of unstable modes and the damping rate, or the pulsation frequency, of the stable modes as a function of the friction parameter and shielding length. For specific equations of state, we express the stability criterion in terms of cell density.

  4. Jean-Martin Charcot and his legacy.

    Jean-Martin Charcot (1825-1893) rightly is considered the father of both modern neurology and psychiatry in France and much beyond. While he never was interested in mental disease and what was called 'alienism' at the time, his career at La Salpêtrière Hospital over 30 years was mainly marked by the development of a huge group of students which focused on the study and management of hysteria. When Charcot took office at the beginning of 1862, hysteria was a 'no-man's land', medically speaking, since neither the alienists nor the internists had much interest in this condition. At La Salpêtrière, these chronic patients were largely left to themselves before Désiré Bourneville, one of Charcot's first students, convinced his chief to care for them. Subsequently, the studies of Charcot with Paul Richer, Joseph Babinski, Georges Gilles de la Tourette, Paul Sollier, Pierre Janet, and many others allowed the condition to be addressed in detail. During his stay with Charcot in 1885-1866, Sigmund Freud, a young neuropathologist at the time, became fascinated by hysteria, an interest which probably was the main start of his interest in psychology. Charcot emphasized the concept of mental factors in hysteria, along with that of a 'dynamic' lesion, which accounted for the lack of neuropathological findings in the patients. While his ideas on hysteria and hypnotism were criticized after his death even by former pupils, such as Babinski, recent findings from functional studies using magnetic resonance imaging show how accurate and often visionary Charcot's thinking was in this field.

    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.

    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. PMID:11970688

    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.

  1. THERMALLY DRIVEN ATMOSPHERIC ESCAPE: TRANSITION FROM HYDRODYNAMIC TO JEANS ESCAPE

    SciTech Connect

    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}. 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.

    2014-07-15

    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 the 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.

Compared with Maxwellian scenario, suprathermality stabilized the Jeans instability.

    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 would 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.

    2009-10-15

    Electrostatic drift waves (EDWs) are investigated in nonuniform quantum magnetized dusty plasmas by taking into account dust gravitational effects with the help of the quantum hydrodynamic model. Ions and electrons are viewed as low-temperature Fermi gases, whereas quantum effects are neglected for the dust grains. The analytical dispersion relationship of the quantum EDWs is derived. Quantum effects are shown to affect the dispersion of EDW significantly. The Jeans terms induce a driftlike instability, which does not exist with the absence of gravitational effects. The criteria and growth rate of the kind of instability are presented. Our results are relevant to dense astrophysical objects such as the interiors of astrophysical compact objects (e.g., white dwarfs and neutron stars)

    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. PMID:17152748

    Transcultural nursing care is a well-established theoretical framework. This theory, developed by Madeleine Leininger, can have an impact on clinical practice, academic preparation and nursing research. The heightened interest in applying transcultural care and the increased need to espouse this framework have been triggered by constant population changes. This paper defines transcultural nursing care and expands its definition further by comparing and contrasting it with Jean-Paul Sartre's existentialist perspective. The two modes of existence as defined by Sartre are closely examined. Concrete examples are offered as cultural phenomena and the components of a cultural assessment are discussed and applied. The philosophical thesis is approached from a transcultural nursing perspective and existentialism is shown to serve as a foundation for transcultural nursing. The advantages and disadvantages of transcultural nursing practice and the preparation of transcultural nurses are finally addressed. PMID:7499611

    Jean Rey, a physician from The Bugue, a little town near Bergerac, published, in 1630, a book entitled "Essays" in which he explained the increase of the mass of lead, when it was strongly heated, by the fixation of a part of the air. This revolutionary publication was not received by the European scientists, because the Father Mersenne, "the secretary of learned Europe", was not able to repeat his experiments. Between 1774 and 1775, Pierre Bayen, who was a military apothecary, published his Works concerning the "precipitate per se", for us HgO, showing that when this compound was destroyed by heating, it produced a gas, and that the mass of this gas and the mass of the mercury obtained were equal to the mass of the "precipitate per se". He concluded that the phlogiston theory was contradictory with the results of the experiments. When, later on, Lavoisier published his important article on the increase of the mass of steal when it was heated in the air, he "forgot" to cite the Works of Bayen. In January 1775, Pierre Bayen published a letter in which he mentioned that he had discovered an exemplar of Jean Rey's book and explained that this physician of the 17th century had supposed the explanation that had been proved by Lavoisier. Nicolas Gobet then published a new edition of the "Essays" in 1777, but this new edition became itself quite rare. An inscription pencilled on the book kept by the British Museum pretends that all the exemplars Lavoisier could find were destroyed. It is not rigorous to conclude on a single document, especially when it is not signed, but it is sufficient to induce doubt. PMID:25671980

    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 the 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.

    Physician, scientist and revolutionary are the biographical aspects that had better summarize the life of Jean-Paul Marat (1743-1793). Due to the role that he played during the French Revolution, his work as a physician and scientist, prior to the events of l789, was forgotten. Marat made important contributions in the area of optics and electricity reflected in numerous publications, as well as translating Newton's Opticks (1787). Well known for his radical and aggressive ideas, his political vocation led him to embrace the revolutionary cause after the events of the Bastille. His figure was not indifferent to his contemporaries; although considered a hero by the poorest citizens, aristocrats and bourgeois considered him a cruel extremist. During the last years of his life, he suffered a cutaneous disease, the diagnosis of which is still a matter of controversy. Proposed diagnoses include eczema, seborrheic dermatitis, scabies and dermatitis herpetica, among others.

    Bonnet, Roger-Maurice

    2013-04-01

    The launch of Sputnik-1 triggered my fascination for space at the age of 20. The past 50 years have allowed me to study the Sun with sounding rockets and satellites, revealing the complexity of our star, contributing to the understanding of its physics, and offering surprising manifestations of its behavior and of its effects on Earth. Building instruments for space astronomy, managing teams of space scientists and engineers, led me to become the science director of the European space agency between 1983 and 2001 where I formulated and managed the Horizon 2000 program, which led Europe to occupy the front row of world space science. The Jean Dominique Cassini Medal Lecture offers me an opportunity, to describe the most spectacular achievements of this long-term plan and to outline some basic principles for reaching success, including the essential role of international cooperation with shared partnership. The Lecture also identifies key problems and controversial issues that space astronomy and exploration will face in the 21st century.

  1. Jean-Martin Charcot: neurologist by avocation, nephrologist by yearning.

    PubMed

    Eknoyan, Garabed

    2011-01-01

    In an age of medical advances and specialization, Jean-Martin Charcot (1825-1893) helped found the discipline of neurology and in 1882 was appointed the first Professor of Diseases of the Nervous System in France. As an investigator with broad interests and vast knowledge, Charcot contributed to several other disciplines. An early mentor and dominant figure in Charcot's formative years was Pierre Rayer (1793-1867), famous for his seminal contributions to the study of the kidney, who gifted to Charcot his passion for clinical pathological correlations and likely a yearning for the study of kidney diseases. Famous for the clarity and incisiveness of his formal teaching presentations, Charcot lectured on the kidney at the Faculty of Medicine in Paris in 1877. Translated into English and published as a book titled Lectures on Bright's Disease, those lectures became widely accessible and quoted in the literature through the 1940s. In addition, at a time when he was already concentrating on the study of neurological disorders, Charcot maintained his life-long interest in the kidney and published original studies on the pathological changes of the kidney in gout and experimental lead poisoning, as well as supporting a study of hysterical ischuria by his students.

    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.

    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

  4. Did Jean-Martin Charcot contribute to stroke?

    2010-01-01

    Stroke was never identified as a significant, autonomous field of activity of the emerging school of neurology at La Salpêtrière, which developed after the appointment of Jean-Martin Charcot (1825-1893) during the last days of 1861. However, stroke was already present in Charcot's first paper (1851), which dealt with a case of multiple organ cardiac embolism, including middle cerebral artery infarction, at a time when the studies of Rudolf Virchow on thromboembolism were unknown in France. A few years later, Charcot made a still up-to-date description of vascular intermittent claudication, which had only been reported in the horse. In the 1860s, Charcot and his pupils presented several major works dealing with cerebrovascular disease, including famous studies on miliary aneurysms in cerebral hemorrhage. This work was done with Charles Bouchard, at the time Charcot's 'interne', but who would become one of his 'political' opponents 2 decades later, when in 1892, as president of the 'agrégation' jury, he rejected the professorship application of 4 protégés of Charcot, including Joseph Babinski and Georges Gilles de la Tourette. Further work on cerebrovascular disease by Charcot included histological studies of brain 'softening', paraneoplastic cerebral arterial occlusion and consequences of stroke (e.g. arthropathies, vegetative changes, contractures and abnormal movements). Brain localization, one of Charcot's major neurological topics, was also largely based on stroke case studies. Charcot's work on stroke remains poorly recognized, but it demonstrates his unique skills in stimulating scientific work in younger colleagues, many of whom subsequently became major figures of neurology and psychiatry.

    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

  6. Design jeans for recycling: a supply chain case study in The Netherlands.

    2014-11-01

    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. PMID:25245293

  8. Secondary instability of Jeans mode in a gravitating fluid with uniform rotation

    SciTech Connect

    Chakrabarti, Nikhil

    2011-06-15

    An axisymmetric rotating gas in a gravitational field is examined for its stability to two dimensional disturbances with first azimuthal mode. It is shown that a quasi-equilibrium is established when pressure and Coriolis force act against primary Jeans instability. A linear perturbation on this inhomogeneous equilibrium gives rise to secondary instability, which grows differently from homogeneous case. A stationary phase integral method demonstrates that the instability grows algebraically due to the free energy associated with the axisymmetric equilibrium. This secondary Jeans instability may have some bearing with the structure formations in the universe.

    In his analysis of football hooliganism, Anthony King claims to reveal the historical, conceptual scheme young, male supporters draw upon. This 'masculine vision', he states, is similar to that held by the Freikorps. Both groups are said to adhere to modernist notions of masculinity, sexuality and nationhood, reinforced by rituals which maintain boundaries between these 'proper' males and deviant 'others'. Occasionally, football hooligans breach these boundaries in acts of postmodern transgression. King also claims that fans link sex and violence in their imaginations. In this response I examine King's critique of his fellow theorists; challenge his 'Freikorps-Fans' analogy; demonstrate the problem he has in establishing the sex-violence link and question the relevance of his concept of postmodernity.

    NASA Astrophysics Data System (ADS)

    Cadez, V. M.

    1990-08-01

    The applicability of standard normal mode analysis with the resulting gravitational instability criterion is discussed for some typical configurations. It is shown that the small-perturbation method, generally used in the literature, has to be applied locally only, the reason being that the medium of a self-gravitating cloud cannot be considered homogeneous throughout the whole space. Consequently, there is an upper limit to the geometrical size of a perturbation, defined by the typical inhomogeneity scale length L. On the other hand, according to the Jeans criterion, the gravitational instability sets in for perturbations having their linear dimensions larger than some critical length, L(J), the Jeans length. It is therefore of some importance to estimate the value of the ratio L/L(J) in order to be sure that the local-analysis conclusions are meaningful.

    For the region after the recombination era of the universe, the hydrodynamical density waves are analyzed, including shear viscosity and heat conduction for densities equal to and less than the critical density of the universe. Very near to the end of the recombination era (z = 1200), the well-known Jeans instability is found. Although the influence of the shear viscosity on the instabilities is negligible, a visible influence of the bulk viscosity is found to be present.

It appears that the young Piaget's interest in psychoanalysis largely emanated from his long-standing problems with his mother. It is suggested that Piaget's lifelong tendency to intellectualise his own emotional experiences may relate to the near omission of affective factors in his psychological theories. PMID:8491531

The central themes of Sartre's personal existence are shown to revolve around a struggle for self-definition and self-formation, rooted in the empathic failures of significant others during his formative years. It is argued that Sartre's experience of this struggle is mirrored and symbolized by the dialectic of being and nothingness which constitutes the central preoccupation of his philosophy.

    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 for 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.

    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.

    We study the internal kinematics of galaxy clusters in the region beyond the sphere of virialization. Galaxies around a virialized cluster are infalling towards the cluster centre with a non-zero mean radial velocity. We develop a new formalism for describing the dynamical state of clusters, by generalizing the standard Jeans formalism with the inclusion of the peculiar infall motions of galaxies and the Hubble expansion as well as the contributions due to background cosmology. Using empirical fits to the radial profiles of density, mean radial velocity and velocity anisotropy of both a stacked cluster-mass halo and two isolated haloes of a cosmological dark matter only simulation, we verify that our generalized Jeans equation correctly predicts the radial velocity dispersion out to 4 virial radii. We find that the radial velocity dispersion inferred from the standard Jeans equation is accurate up to 2 virial radii, but overestimated by ≈20 per cent for the stacked halo and by ≈40 per cent for the isolated haloes, in the range ≈2-3 virial radii. Our model depends on the logarithmic growth rate of the virial radius (function of halo mass or concentration), which we estimate in seven different ways, and on the departure from self-similarity of the evolution of the peculiar velocity profile in virial units.

    This paper aims to analyze Jean Laplanche's revision of Freudian metapsychology, which emerged from a critical return to Freud's officially abandoned seduction theory of 1895-1897. Where Freud gradually replaced the model of traumatic seduction with a theory of infantile sexuality and its drives, Laplanche articulates both trauma and sexual drive in a new theory of primal seduction, the fundamental anthropological situation in which human subjectivity is formed. The author concludes by considering Laplanche's modeling of the psychoanalytic situation and his reformulation of transference in relation to mourning and sublimation within the framework of the general theory of seduction.

    We study a rigid classical extended charge in the nonrelativistic approximation, first subjected to a linear force, and second immersed in an electromagnetic radiation with a Rayleigh-Jeans (RJ) spectrum. A Yukawa distribution is considered for the charge, when necessary, to get explicit results. A comparison with the Abraham-Lorentz (AL) model is made. Our results show that the AL model is a good approximation for the extended charge only if the external forces do not contain high frequencies. However, if we consider RJ radiation big discrepancies appear. We also find that the linear system follows the Maxwell-Boltzmann law only for large enough values of the radius.

The sources for this paper are Dewey's studies on logic and the theory of inquiry and Piaget's historical-critical and psychogenetic investigations. Three major conclusions result from the comparison: first, there are significant convergences between the two theories; second, Piaget's developmental analysis makes explicit what is programmatic in Dewey's investigations; and, finally, Piaget is incorrect in characterizing Dewey's pragmatism as a method that does not meet the criteria of intelligent activity.

    The fields of emergency medicine and resuscitation are indebted to the Baron Dominique-Jean Larrey (1766-1842) for significant advances in patient care. Larrey was a great surgeon who served in the French army during Napoleon's rule. He developed one of the first ambulance services, utilized positive pressure ventilation, and introduced hypothermia as a form of therapy. He dedicated his professional life to improving the care of wounded soldiers on the battlefield. Larrey coined the term "Triage" to allocate resources to those most in need of emergent care. Today, many of his techniques still prevail in modern medicine. PMID:20036046

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

    NASA Astrophysics Data System (ADS)

    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

    Jean Francheteau's 40-year career as a marine geophysicist spanned an exceptionally broad range of research interests and influenced generations of marine scientists, providing new concepts and insights on accretionary tectonics and seafloor volcanism. Using seafloor mapping techniques that at the time (in the early 1970s) were innovative in their own right, Jean and colleagues provided some of the first detailed perspectives of mid-ocean ridge axial topography that helped solidify acceptance of volcanic accretion at the ridges and specifically the highly focused volcanism occurring within the rift valley of the Mid-Atlantic Ridge. Building on that work, Jean collaborated with many investigators, including one of us (RDB), over several decades of exploratory work that elucidated the fine-scale volcanic and tectonic features of many segments of the global mid-ocean ridge from the Mid-Atlanic Ridge to the northern and southern East Pacific Rise. His work in marine tectonics was equally eclectic and included detailed studies of fracture zones, microplates and exposures of crustal and upper mantle rocks in Hess Deep. Jean excelled at using the latest technologies to investigate and map seafloor volcanic and hydrothermal terrains. His work helped establish routine academic use of multibeam sonar and deep submergence technologies - both towed camera and ultimately submersibles - to make in situ field observations and collect samples. In so doing, Jean and colleagues amassed a vast amount of data pertaining to submarine volcanic and hydrothermal processes and he was one of the first to help establish causal links between these processes and their distribution along and across spreading center axes separating at slow to ultra-fast rates. Jean's superb mentorship of young marine scientists, involving them in both field and laboratory studies was a hallmark of his gracious style and reflects one of the many ways in which he admirably served the international oceanographic

    We show that the formation of a magnon condensate in thin ferromagnetic films can be explained within the framework of a classical stochastic non-Markovian Landau-Lifshitz-Gilbert equation where the properties of the random magnetic field and the dissipation are determined by the underlying phonon dynamics. We have numerically solved this equation for a tangentially magnetized yttrium-iron garnet film in the presence of a parallel parametric pumping field. We obtain a complete description of all stages of the nonequilibrium time evolution of the magnon gas which is in excellent agreement with experiments. Our calculation proves that the experimentally observed condensation of magnons in yttrium-iron garnet at room temperature is a purely classical phenomenon which should be called Rayleigh-Jeans rather than Bose-Einstein condensation.

    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 Zn 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.

    In 1871, the Belgian astronomer Jean-Charles Houzeau developed a new approach to determine the solar parallax. His "heliometer with unequal focal lengths" produces a large and a small solar image, as well as a large and a small image of Venus. Making the small solar and the large Venus image coincide yields a measure of the angular distance of the centers of both objects. Two such instruments were built for two Belgian expeditions to observe the Venus transit of December 6, 1882: one to San Antonio, Texas, and another one to Santiago de Chile. These were the first major expeditions in the history of Belgian science. This paper documents the expeditions, and clarifies the principal instrument and its present-day whereabouts.

Based on the previously derived modified Navier—Stokes hydrodynamic equations (the so-called equations of q-hydrodynamics), we have analyzed the axisymmetric oscillations of an astrophysical, differentially rotating gas—dust cosmic object and obtained modified Jeans and Toomre gravitational instability criteria for disks with a fractal phase-space structure.

    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.

    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.

  12. A NEW METHOD TO DIRECTLY MEASURE THE JEANS SCALE OF THE INTERGALACTIC MEDIUM USING CLOSE QUASAR PAIRS

    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

    BIOGRAPHY: Baron Dominique Jean Larrev was a French army surgeon who rose to become a surgeon-in-chief of Napoleon's Grande Armée. Many advances in the field of surgery have been attributed to him: he was one of the first to amputate at the hip-joint (1812); he pioneered the use of maggots to prevent infection in wounds; he gave the first description of a trench foot, and originated the first aid to combatants by getting stretcher-bearers to take wounded men immediately from the battlefield. EDUCATION AND CAREER: Larrey studied medicine in Paris and spent a short time in the navy before resuming his studies at the Parisian College de Chirurgie. He joined the army in 1792 and spent the rest of his active life there, taking part in 60 battles and 400 other engagements, having been wounded three times. During this time, he initiated the modern method of army surgery, field hospitals and the system of army ambulance corps. After seeing the speed with which the carriages of the French flying artillery manoeuvred across the battlefields. Larrey adapted them as Flying Ambulances for rapid transport of the wounded and staffed them with trained crews of drivers, corpsmen and litter-bearers. Larrey also increased the mobility and improved the organization of field hospitals, effectively creating a forerunner of the modern MASH (Mobile Army Surgical Hospital) units. He was made a baron in 1809. He remained loyal to Napoleon even after his abdication in 1814, and followed him on his final campaign (the hundred days). At Waterloo, he was captured and sentenced to death; however, he was saved by the personal intervention of the Prussian commander Blücher. Many historians put him in the line with chemist Antoine Lavoisier and doctors Joseph Guillotin and Jean Paul Marat. PMID:21548278

  14. Jeans Analysis of the Galactic Thick Disk and the Local Dark Matter Density

    Dynamical estimates of the mass surface density at the solar radius can be made up to a height of 4 kpc using thick disk stars as tracers of the potential. We investigate why different Jeans estimators of the local surface density lead to puzzling and conflicting results. Using the Jeans equations, we compute the vertical (Fz) and radial (FR) components of the gravitational force, as well as Γ(z), which is defined as {{Γ }}\\equiv \\partial {V}{{c}}2/\\partial R, with {V}{{c}}2\\equiv -R{F}R. If we assume that the thick disk does not flare and that all the components of the velocity dispersion tensor of the thick disk have a uniform radial scalelength of 3.5 kpc, Γ takes implausibly large negative values when using the currently available kinematical data of the thick disk. This implies that the input parameters or the model assumptions must be revised. We have explored, using a simulated thick disk, the impact of the assumption that the scalelengths of the density and velocity dispersions do not depend on the vertical height z above the midplane. In the absence of any information about how these scale radii depend on z, we define a different strategy. By using a parameterized Galactic potential, we find that acceptable fits to Fz, FR, and Γ are obtained for a flaring thick disk and a spherical dark matter (DM) halo with a local density ≳0.0064 M⊙ pc-3. Disk-like DM distributions may be also compatible with the current data of the thick disk. A precise measurement of Γ at the midplane could be very useful for discriminating between models.

    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. PMID:21178190

  16. Birth of modern psychiatry and the death of alienism: the legacy of Jean-Martin Charcot.

    At the time of Jean-Martin Charcot, Paris--the main center for studies on the nervous system and its disorders--was home to critical exchanges between the developing discipline of neurology and psychiatry. Contrary to the commonly held view, and in spite of an established tradition concerning mental diseases, emerging neurology had a much stronger influence on psychiatry ('alienism') than the reverse. This was largely due to the school built up by Jean-Martin Charcot himself, which was organized around the study and management of hysteria. Although Charcot always claimed to be uninterested in mental medicine, he stimulated the development of an original scientific approach to nervous system conditions, based on Claude Bernard's method, along with structured academic teaching. Conversely, alienism paradoxically remained stuck in organicism, after Antoine Bayle's report in 1822 of 'arachnitis' as the substratum of general paresis of the insane. Contrary to alienism, the young neurological school was capable of self-criticism, and progressively highlighted mental factors in hysteria. This led to the paradox that neurologists were active in a disease with no organic cerebral lesion, while alienists were postulating brain lesions in all mental disorders. Pushed by Charcot, the academic evolution led to the launch of a faculty chair of mental and brain diseases in 1875, which was taken over for nearly half a century by his direct pupils Benjamin Ball, Alix Joffroy and Gilbert Ballet, who held the position until 1916, supporting the development of modern psychiatry in general hospitals, while alienism progressively disappeared at the turn of the century.

    Jean-Baptiste Vincent Laborde (1830-1903), native of Buzet, in Gascony, undertook his medical studies in Paris and was nominated "externe" (1854) then "interne" (1858) of Paris hospitals. His main "patrons" were Alfred Velpeau (1795-1867), Auguste Nélaton (1807-1873), Jean-Baptiste Bouillaud (1796-1881), Pierre-Olive Rayer (1793-1867), Joseph-François Malgaigne (1806-1865), Pierre Carl Edouard Potain (1825-1901), Ernest Charles Lasègue (1816-1883) and Léon Rostan (1790-1866). In 1864 he defended his thesis on the essential paralysis of childhood. He then worked in the physiology laboratory of Professor Jules Auguste Beclard (1818-1887), and became "chef des travaux" of physiology at the Paris faculty of medicine. In 1890, he was nominated to the chair of Biological anthropology at the Paris school of anthropology. His main works focused on the rhythmic tractions of the tongue in cases of apparent death, the understanding of the etiology of brain softening he attributed to vascular occlusions by atheroma and the discovery of connections between the cranial nuclei of common (III) and external (VI) oculomotor nerves and the struggle against the use of ceruse, against tuberculosis and especially against alcoholism. In addition, he made a career in journalism: since 1874 he had been the founder, director and editor-in-chief of the weekly newspaper The Medical Tribune, whose aim was to "combine to a fair extent, science and progress with the practice of medicine." Finally, Laborde was a convinced Republican, a friend of Léon Gambetta's (1838-1882). For him, democracy was the "ideal of civilized nations" and he showed deep hatred for the "Commune of Paris". Finally, he was a determined free thinker, who ran the Society for mutual autopsy for a while and who was attached to civil funerals and cremation. PMID:25786426

    The general post-glacial evolution of the Lake Saint-Jean region (Canada/Québec) was, until now, only known from onshore studies (outcrops and geomorphology). Because this lake corresponds to sediment depocentre since the area is ice free (latest Pleistocene and the entire Holocene), a comprehensive sedimentary archive could be expected from this area. As a consequence, the offshore archives of Lake Saint-Jean leave a basic, but crucial, question: can the transition from glacial to post-glacial periods be deciphered? The stratigraphy of the last deglacial sequence is investigated in Lake Saint-Jean (Québec, Canada) from 300 km of echo-sounder 2D seismic profiles. The sedimentary archive of this basin is documented from the Late Pleistocene Laurentidian ice-front recession to the present-day situation. Ten seismic units have been identified that reflect spatio-temporal variations in depositional processes characterizing different periods of the Lake Saint-Jean basin evolution. During the postglacial marine flooding, a high deposition rate of mud settling, from proglacial glacimarine and then prodeltaic plumes in the Laflamme Gulf, produced an extensive, up to 50 m thick mud sheet draping the isostatically depressed marine basin floor. Subsequently, closing of the water body due to glacio-isostatic rebound that occurred at 8.5 cal. ka BP and ice-sheet retreat outside the Saint-Jean catchment at 7.5 cal. ka BP drastically modify the hydrodynamics and sedimentation. Hyperpycnal flows appeared because fresh lake water replaced dense marine water. River sediments were transferred towards the deeper part of the lake into river-related confined lobes. The water body is also marked by the onset of a wind-driven internal circulation associating wave-related hydrodynamics and bottom currents with sedimentary features including shoreface deposits, sediment drifts, a sedimentary shelf and important erosional surfaces.

    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.

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 theories of Jean Piaget and William Perry provide two different theories of intellectual development with several similiarities, but also with critical differences. In this study a comparison was made to determine whether the two theories describe operation of the same mental structures or two fundamentally different aspects of intellectual development. The results, based upon individual interviews of all participants, indicate that the two theories outline different and independent processes for assessing intellectual development.

    The problem of Jeans gravitational instability and radiative instability is investigated for partially ionized self-gravitating plasma which has connection in astrophysical condensations and formation of objects. A general dispersion relation has been derived with the help of relevant linearized perturbation equations, using the normal mode analysis method. Effects of FLR corrections, radiative heat-loss function and collisions with neutrals on the Jeans criterion of self-gravitational instability of the system are discussed. The conditions of instability are derived for a temperature-dependent and density-dependent heat-loss function with thermal conductivity and FLR corrections for some special case. The stability of the system is discussed by using Routh-Hurwitz's criterion. Numerical calculations have been performed to discuss the dependence of the growth rate of the Jeans gravitational instability on the various physical parameters. The FLR corrections, viscosity, porosity, magnetic field, and neutral collision have stabilizing influence while finite electrical resistivity and permeability have a destabilizing influence on the growth rate of the gravitational instability. Our results are helpful for understanding the formation of dense molecular clouds.

    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! PMID:23739320

    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

    We present an update of the CLUMPY code for the calculation of the astrophysical J-factors (from dark matter annihilation/decay) for any Galactic or extragalactic dark matter halo including substructures: halo-to-halo concentration scatter may now be enabled, boost factors can include several levels of substructures, and triaxiality is a new option for dark matter haloes. This new version takes advantage of the cfitsio and HEALPix libraries to propose fits output maps using the HEALPix pixelisation scheme. Skymaps for γ-ray and ν signals from generic annihilation/decay spectra are now direct outputs of CLUMPY. Making use of HEALPix routines, smoothing by a user-defined instrumental Gaussian beam and computing the angular power spectrum of the maps are now possible. In addition to these improvements, the main novelty is the implementation of a Jeans analysis module, to obtain dark matter density profiles from kinematic data in relaxed spherical systems (e.g., dwarf spheroidal galaxies). The code is also interfaced with the GreAT toolkit designed for Markov Chain Monte Carlo analyses, from which probability density functions and credible intervals can be obtained for velocity dispersions, dark matter profiles, and J-factors.

    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.

    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.

    Jean-Charles Houzeau de Lehaie (1820-1888) was a Belgian astronomer who, as an observer, covered astronomy, geography, cartography, geodesy and natural sciences. He is known for designing the ``heliometer with unequal focal lengths" for the 1882 transit of Venus, for which he organised two expeditions: one to San Antonio (Texas), and one to Santiago (Chile). Less known, but historically important from the point of view of his consistent approach to observational science, was his ``Uranométrie générale", in which he systematically recorded visual magnitudes of 5719 northern and southern stars up to mag 6.4. He carried out the visual estimates from Jamaica in less than 400 nights in 1875--76. This presentation discusses the observational approach of his project, and weighs the merit of a dataset that was produced in one throw, by one single person from one single observing site of excellent atmospheric quality, without any recourse to data produced by other observers. A proving example of the virtue of Houzeau's Uranométrie is that it has been used in the construction of the charts of the first edition of ``Norton's Star Atlas".

    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.

    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.

    2009-03-01

    This paper explores Jean-Luc Nancy's philosophical reflection on surviving his own heart transplant. In 'The Intruder', he raises central questions concerning the relations between what he refers to as a 'proper' life, that is, a life that is thought to be one's own singular 'lived experience', and medical techniques, shaped at this particular historical juncture by cyclosporine or immuno-suppression. He describes the temporal nature of an ever-increasing sense of strangeness and fragmentation which accompanies his heart transplant. In doing so, Nancy opens up the concealed of transplantation in terms of the problematic 'gift' of a 'foreign' organ, the unremitting suffering intrusiveness of the treatment regimen, and the living of life as 'bare life'. He uncovers and exposes the relentless uncanniness that pervades the post-transplant experience, which for him is an example of our humanistic, never-ending impulse, to alter ourselves. Nevertheless, Nancy offers no answer to this dilemma, but instead calls us to think about the meaning or 'sense' of the prolonging of life and deferring of death, which currently drives our medical interventions.

For thirteen (13) years he worked as a journeyman apothecary was like a drysalter grocer.

Long before the 1777 nationwide statutes due to king Louis XIV (the fourteenth). To become a master, Magnol had to give four masterpieces, the formulas of which can be found in the new pharmacopoeia written by the medicine chancellor: "the pharmacopoea Monspeliensis" an alternative to the ancient one by Nicolas de Salerne. The pratical experiments were carried out by those famous apothecary masters who made up the 1572 statutes.

    Jean-Martin Charcot (1825-93) was a well-known French neurologist. Although he is widely recognized for his discovery of several neurological disorders and his research into aphasia, Charcot's ideas about how the brain processes music are less well known. Charcot discussed the music abilities of several patients in the context of his 'Friday Lessons' on aphasia, which took place at the Salpêtrière Hospital in Paris in 1883-84. In his most comprehensive discussion about music, Charcot described a professional trombone player who developed difficulty copying music notation and playing his instrument, thereby identifying a new isolated syndrome of music agraphia without aphasia. Because the description of this case was published only in Italian by one of his students, Domenico Miliotti, there has been considerable confusion and under-acknowledgement of Charcot's ideas about music and the brain. In this paper, we describe Charcot's ideas regarding music and place them within the historical context of the growing interest in the neurological underpinnings of music abilities that took place in the 1880s.

Bourneville, E. Brissaud, P. Marie and G. Gilles de la Tourette. Others are less well known. The fact remains that Charcot knew how to surround himself with fine students and leverage their talents in order to make the neurological discoveries by which he would become famous throughout the world. Here, we present the biographies of H. Soulier (1862), J. Cotard (1865), R. Lépine (1867), A. Gombault (1872), A. Pierret (1874), A. Pitres (1876), P. Oulmont (1877), G. Guinon (1885), P. Blocq(1887), E. Huet (1888), E. Parmentier (1890) and A. Souques(1893). Each of these men with their unique paths and interests helped lay the foundations for the birth of neurology at the end of the 19th century in Paris. As Emile Littré said: 'La science de la Médecine, si elle ne veut pas être rabaissée au rang de métier, doit s'occuper de son histoire et soigner les vieux monuments que les temps passés lui ont légués', which could be translated as 'to avoid being reduced to a trade, the science of medicine must attend to its history and take care of the old monuments handed down by time'.

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

    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].

    One of the most significant contributions to tropical medicine and ophthalmology was made by Jean Hissette: African ocular onchocerciasis. During his extensive investigations in the Babindi country, he found numerous adults with river blindness. Their eye disease was caused by the filaria Onchocerca volvulus Leuckart. He noticed the signs of interstitial keratitis and band keratopathy, faint iritis or iridocyclitis, posterior synechiae and often a downward distortion of the pupil. He was the first to describe chorioretinal scarring of the fundus, what became known as the Hissette-Ridley fundus. People reported to him their entoptic phenomena which he unequivocally interpreted to be the images of microfilariae in the patient's own eye. During his stay in Belgium in 1932, he elucidated the pathogenesis of blindness since he was able to provide histological proof of the presence of microfilariae in various ocular tissues of an enucleated eye from a patient living near the Sankuru river. Like other serious health impairments, the severe inflammatory lesions in the eye occurred only after the microfilariae had died. Hence he realized that dying microfilariae play a key role in the mechanisms leading to blindness. Hissette's precise descriptions were the logical fruit of his outstanding observational abilities and enabled him as a man of great intuition to speculate about causal relationships. He evidently benefited from the fact that he took the native Africans seriously and asked them their opinion. In 1933, his friend and teacher Dr. De Mets in Antwerp already wrote on Hissette's discovery in the Belgian Congo: "This study is of exceptional value to specialists which is not only a tribute to its author, but to our common native country (Belgium)."

    Jean-Martin Charcot (1825-1893) was the premier clinical neurologist of the 19th century. Charcot's research was anchored in the anatomo-clinical method, a two-part methodology that linked clinical signs with anatomical lesions. The first step of this method involved the careful documentation of clinical signs with longitudinal observation. At the time of death, the second step involved autopsy examination of the brain and spinal cord. With combined clinical and anatomical data, Charcot was able to suggest concrete clinical-anatomical correlations. This method helped to define the tracts and nuclei responsible for normal and abnormal neurological signs and was pivotal to a new classification of neurological diseases based on anatomy. The best-developed example of this method was Charcot's work with motor system degenerative disorders, specifically amyotrophic lateral sclerosis. These studies led to the international designation of amyotrophic lateral sclerosis as Charcot's disease. Other examples of the fruits of the anatomo-clinical method included several stroke syndromes and the linkage of specific signs to specific lesions in multiple sclerosis. The discipline fostered cortical localization theory, which moved neurologists away from the concept of the brain as a homogenous organ in preference to the concept that brain regions controlled specific motor, sensory and language functions. Charcot's attempts to apply his anatomo-clinical method to the knotty neurological diagnosis of hysteria led him to experiments and conclusions that drew criticism and even scorn from colleagues. These events tarnished Charcot's reputation at the close of his career. In the context of Charcot's extensive discoveries and lasting contributions, the anatomo-clinical method remains the anchor of modern neurological diagnosis and is Charcot's most important contribution to clinical neurology.

    2015-01-01

    In order to locate copies of the works of Jean Emmanuel Gilibert (1741-1814) located in Poland, 54 libraries were selected for inquiry, chosen on the basis of their history or of the nature or size of their collections. So far, 27 libraries have responded to the inquiry. There are works of J.E. Gilibert stored in 14 of them (Table 1). To date, 102 copies of different editions catalogued under Gilibert's name have been recorded in libraries in Poland. These books were placed in these libraries in the nineteenth and early twentieth centuries, mainly as part of donations from private libraries. In Poland, the reception of the botanical works of J.E. Gilibert changed over time. Initially they were accepted uncritically (Stanisław Bonifacy Jundzill, Józef Jundziłł). Over time, and with the increase in floristic data subsequent to the publication of Gilibert's works, his treatises were cited less frequently. As early as the second half of the nineteenth century, Polish botanists mentioned them only occasionally. More accurate works, containing newer taxonomical considerations of species, effectively supplanted the works of Gilibert in scientific circulation. It is worth noting that for contemporary plant taxonomy, the botanical works of Gilibert are of no scientific value. Four of them (Flora lituanica inchoata, Exercitium botanicum, Caroli Linnaei botanicorum principis, Exercitia phytologica) are listed in Appendix V, 'Opera Utique Oppressa', of the 2006 Vienna Code of Botanical Nomenclature. Names appearing in these works in the rankings specified at the end of each listing (species and intraspecific taxa) are not accepted as valid. PMID:26445749

    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 continue the study of the problem of equilibrium between radiation and classical relativistic systems begun previously

    [Phys. Rev. D 27, 1254 (1983)]
    . We consider the emission and absorption of energy by a relativistic pointlike particle immersed in a Rayleigh-Jeans radiation field. The particle is acted upon by a force which, if alone, would produce a multiply periodic motion. It is shown that radiative balance at each frequency holds. A discussion is given of the results reported in both papers.

    We analyze in detail the validity of the compatibility between the Maxwell-Boltzmann (MB) distribution and the Rayleigh-Jeans (RJ) spectrum obtained in recent works by the authors for classical relativistic systems. We show that the MB distribution and the RJ spectrum are not compatible if we do not remove high enough frequencies. By analyzing the applicability of the approximation methods used in previous works to obtain the MB distribution from the RJ spectrum, we conclude that these methods are valid only if we introduce a high-frequency cutoff in the RJ spectrum. A short discussion is made on the meaning of this cutoff.

    Three diterpenoids, 1-oxomicrostegiol (1), viroxocin (2), viridoquinone (3), were isolated from the roots of Salvia viridis L. cvar. Blue Jeans. Five known diterpenoids, microstegiol (4), 7α-acetoxy-14-hydroxy-8,13-abietadiene-11,12-dione (5; 7-O-acetylhorminone tautomer), 7α,14-dihydroxy-8,13-abietadiene-11,12-dione (6; horminone tautomer), ferruginol and salvinolonyl 12-methyl ether (7) were also found in the roots together with 1-docosyl ferulate (8), and a mixture of 2-(4'-alkoxyphenyl) ethyl alkanoates (9). Two lupane triterpenoids, 2α-acetoxy-lup-20(29)-en-3β-ol (10), and 3β-acetoxy-lup-20(29)-en-2α-ol (11) were found in the aerial parts together with known compounds, lup-20(29)-ene-2α,3β-diol (12), ursolic acid, oleanolic acid, β-sitosterol and β-sitosterol glucoside. A known phenylpropanoid, trans-verbascoside (or acteoside; 13), was the main constituent in the polar fraction of the aerial part, and it is now reported in the genus Salvia for the first time. Other polyphenolic compounds were cis-verbascoside (14), leucosceptoside A (15), martynoside (16), caffeic acid, 6-O-caffeoyl-glucose (18), rosmarinic acid, salidroside, luteolin-7-O-α-rhamnopyranosyl-(1→6)-β-galactopyranoside, luteolin-7-O-β-galactopyranoside, luteolin-7-O-α-rhamnopyranosyl-(1→6)-β-glucopyranoside, luteolin-7-O-β-glucopyranoside, and apigenin-7-O-β-glucopyranoside. The structures were determined by 1D-, 2D-NMR and HR-ESI-MS techniques. Compounds 6, 10, ferruginol, ursolic acid and oleanolic acid exhibited antibacterial activity against Enterococcus faecalis (ATCC 775) with MIC 50 μM, 25 μM, 50 μM, 12.5 μM, 12.5 μM respectively. Ferruginol, ursolic acid and oleanolic acid were also active against Staphylococcus aureus (ATCC 6571), and Bacillus cereus (ATCC 2599) with MIC 12.5-50 μM. 4 was also active against S.aureus (ATCC 6571) with MIC 50 μM. These values are consistent with previous studies on the antimicrobial activity of Salvia diterpenoids. PMID:25256822

  3. The fragmentation of molecular clouds - Critical (Jeans) mass in the vicinity of thermal instability and influence of visible extinction variations

    1993-01-01

    We adapt the classical Jeans analysis of gravitational stability to a molecular gas subject to thermal exchanges of the interstellar medium. At the onset of thermal instability the compressibility of a gas vanishes and so does the critical Jeans mass which is proportional to the 3/2 power of the compressibility. A spherical geometry is adopted, taking into account self-consistent variations of the opacity driven by radial density gravitational modes. The variation of the critical mass in the vicinity of thermal instabilities is presented. Nonlinear and nonequilibrium simulations of spherical clouds have been performed to study: the gravitational evolution of a thermally unstable cooling gas, and the influence of ambient radiation field variations upon stability of molecular clumps in the outer envelopes of molecular complexes. Accordingly, the following consequences are discussed: the critical mass reduction by self-consistent variations of the opacity which may occur for example when the ratio of dust to gas is locally enhanced; the location of stable hydrostatic equilibrium of the most massive clumps in large molecular clouds; and the early thermal and gravitational fragmentation of giant molecular clouds during the cooling period of large amounts of warm interstellar gas.

    2015-01-01

    Among the many topics of lively scientific work that Jean Emmanuel Gilibert (1741-1814) conducted in Grodno and Vilnius, an important place is occupied by his observations of wild mammals. Royal patronage and care from Antoni Tyzenhauz, Treasurer of the Grand Duchy of Lithuania and the governor of Grodno, allowed Gilibert to keep and observe wild fauna captured by royal services in royal forests, including Białowieża Primeval Forest. Such was an origin of a female bison kept by Gilibert in Grodno. Its description, published in Indagatores naturae in Lithuania (Vilnius 1781) for decades became the primary source of information about the behaviour, food preferences and the anatomy of European bison. European science has just begun to take interest in European bison, therefore Gilibert's account entered scientific circulation by way of French natural history encyclopaedias (mainly Georges Buffon's Histoire naturelle) and works by Georges Cuvier or Étienne Geoffroy Saint-Hilaire. Apart from the description of European bison, Gilibert left an entire series of observations of wild mammals inhabiting the forests of the Grand Duchy of Lithuania. His accounts of moose were important in building a knowledge base for this species. In the first half of the 18th century, moose was known mainly from fantastic descriptions in Renaissance works and from prescriptions devoted to using moose hoof as the epilepsy treatment. Gilibert's observations helped to overthrow such superstitions. Similarly, Gilibert's first-hand information verified the widespread legends concerning brown bear (e.g. the belief that white bears, belonging to other species than polar bears, occur in Lithuania) . List of species kept and thoroughly watched by the scholar is much longer and includes lynx, wolf (and hybrids of wolves and dogs), beaver, badger, fox, hedgehog, and even white mouse. Also his comments on the species of mammals then absent in Lithuania but known either from farming or from the fur

    This paper presents new information on the journey of the French geologist Jean-Étienne Guettard to Poland in the years 1760-1762. Search in the Archives of the Academy of Sciences in Paris, especially a review of his biographic dossier and collections of documents reports delivered at the meetings of the Academy, made it possible to find rich material (letters, reports, notes from field studies, drafts of lectures and others), a large part of which refers to this journey. This hitherto overlooked material well supplements our knowledge of the journey and casts some new light on the scope and extent and results of geological and meteorological studies carried out by J.-É. Guettard during his stay in Poland. To cite this article: R. Tarkowski, C. R. Geoscience 336 (2004).

    Jean-Martin Charcot was a pioneer in a variety of subjects, including nervous system diseases; anatomy; physiology; pathology; and diseases of ageing, joints, and lungs. His medical achievements were mainly based on his anatomopathological proficiency, his observation, and his personal thoroughness that favored the delineation of the nosology of the main neurological diseases, including multiple sclerosis, amyotrophic lateral sclerosis, Parkinson's disease, peroneal muscular atrophy, and hysteria/epilepsy. The link of this anatomoclinical method with iconographic representations and theatrical lessons, and the rich bibliographical documentations, carried out in a crowded barn for diseased people--Salpetrière Hospital, were the basis of his achievements, which are still discussed 120 years after his death.

  10. Application of Jean Piaget's theory of human development for nursing children in an adult intensive therapy unit.

    PubMed

    Green, A

    1991-12-01

    Piaget (1964) believed that interaction with the environment has a large part to play in human development. Matthew (1986) states that in an ideal world critically ill children should be cared for by staff trained in paediatrics, within designated paediatric intensive therapy units. Unfortunately, there are only 28 paediatric intensive therapy units in Great Britain (CMA Medical Data, 1987), consequently each year a third of children requiring intensive care are admitted to adult intensive therapy units (ITU). A knowledge and understanding of developmental psychology can therefore be beneficial to nurses in assessing which stage of development a child has reached, in order to plan the correct level of stimulation, and hence facilitate progress rather than regression in the accomplishment of developmental tasks. The psychological and social processes involved in Jean Piaget's (1896-1980) theory of human development are discussed with regard to nursing children requiring intubation and ventilation in an adult ITU.

    Existentialism and phenomenology are closely linked philosophies. Existentialism preceded phenomenology and is not considered a single philosophy but several schools of thought, both theist and atheist in thinking, which grew out of a reaction to traditional philosophy. The development of phenomenology is divided into three separate phases ultimately merging with existentialism. Following Second World War, the phenomenological movement gained momentum in France and encompassed many of the ideas of Edmund Husserl and Martin Heidegger. Gabriel Marcel, Maurice Merlieu-Ponty and, notably, Jean-Paul Sartre established a 'third phase' of phenomenology. This paper explores some of Sartre's ideas related to being and later applications through Medard Boss and R.D. Laing, and offers a short illustrative case vignette that shows the concepts as they might apply to nursing practice. Consideration is finally given to existential psychoanalysis as an applied research methodology PMID:11882149

    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-space 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 ⊙}.

    The art of taking care of the insane developed and solidified at the Hospital Saint-Jean-de-Dieu after a School of Nurses was created there in 1912. Founded by the Sisters of Providence, this new school participated in the transformation of the asylum into a regular hospital. The archives of the Sisters of Providence and the monthly magazine La garde-malade canadienne-française allow us to analyze the discourse of nursing leaders, which was based on the importance of professional training. Scientific discoveries and new technologies were at the heart of the care process at Saint-Jean-de-Dieu, where students were introduced to a technical, as well as a spiritual, education. This article first considers the marginal status of psychiatric nursing training within the larger nurses' professionalization movement. In a second step, it describes the socio-religious context between 1912 and 1962 within which the School of Nurses of the Hospital Saint-Jean-de-Dieu evolved. PMID:21560368

    We report on the development of an extinction map for the Southern Galactic disk based on the combination of Near-Infrared (NIR) observations of the ESO public survey VISTA Variables in the Milky Way (VVV), complemented with GLIMPSE and 2MASS data. The 520 deg{^2} observed by VVV in 5 near infrared bands (J, H, K_{s}, Y, Z), and multiple epochs, are a wealth of information which are important to address fundamental questions about the structure and formation history of the Milky Way. The region surveyed by this work, the 152 VVV tiles/fields of the Southern Galactic disk, overlaps with the 2MASS and GLIMPSE surveys, and thus allows the sources surveyed to have multiband photometry ranging from the near to mid-infrared wavelengths. Our results, using the Rayleigh-Jeans Color Excess method (RJCE), have allowed us to obtain an extinction map with a pixel size of 1'×1', which is consistent with other maps developed recently. Furthermore, our results show a systematic underestimation of extinction by previous work based on 2MASS NIR data alone.

    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." PMID:24041281

    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.

    Jean-Paul Marat was a French revolutionary, famously murdered in his bath by Charlotte Corday in 1793. A lesser known fact is that for over ten years he lived in Britain where he practised as a doctor. During this time he visited London, Edinburgh, Dublin and Holland. Although he had no formal medical training, he published two medical papers on gleets (gonorrhoea) and diseases of the eyes and, on the recommendation of two eminent Scottish physicians, William Buchan and Hugh James, he was granted a medical degree from the University of St Andrews. Marat left no medical legacy and his related writings were forgotten for 100 years until the rediscovery of the two medical papers, which were eventually re-published in 1892 at the instigation of James Bailey, the librarian of the Royal College of Surgeons of England. Biographies by F Chevremont (1880), Ashbee Spencer (1890) and A Cabanès (1891) had rekindled interest in this intriguing revolutionary. A study of his time in Britain and his medical works and training provide an interesting insight into the mind of a revolutionary and how his sojourn may have shaped his future political career upon his return to France in 1777.

I show how Brachet's subsequent conception of messenger RNA evolved in the context of his conceptions of the relations between plasmagenes and nuclear genes. His theorizing on cytoplasmic organelles and viruses is further situated in the bio-political controversy over the inheritance of acquired characteristics during the Lysenko controversy.

    1983-03-01

    The motion of a charged pointlike relativistic particle under the action of a given force field plus a random electromagnetic radiation is studied. It is assumed that the given force field alone should produce a multiply periodic motion, which is perturbed by the action of both the random radiation and the reaction damping. The random radiation is represented by a stochastic process and an equation is obtained for the equilibrium probability density of the particle in phase space. In the particular case of a random radiation with Rayleigh-Jeans spectrum, it is shown that the stationary solution, corresponding to radiation-matter equilibrium, is given by the Maxwell-Boltzmann distribution.

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

    Charcot created a system for the classification and diagnosis of neurological patients in the 1850s. His methodology consisted of listening to a patient's family history and present history, observing the patient scrupulously, and confirming lesions by autopsy once the patient was dead. He compared two different diseases in order to make their differences clear. Once he understood the fundamental form of a disease, he proceeded to study less perfect forms that had a single symptom. By this process, Charcot developed many new symptomatologies in Neurology. PMID:25407058

As a consequence, they provide accurate archive for deciphering environmental change through times. In this contribution, a Late Quaternary deglacial sequence is documented from Lake Saint-Jean basin (Québec, Canada) where sediments have recorded the Laurentide ice sheet (LIS) retreat accompanied by the invasion of marine waters (Laflamme Gulf) from ca. 12.9 cal. ky BP. Subsequently, fluvio-deltaic and then coastal prograding wedges emplaced following the base level fall induced by the glacio-isostatic rebound. The related succession, representing a transition from glacial to post-glacial periods within a previously glaciated area, was investigated through recent geological mapping, preserved landforms, facies analysis, and new optical stimulated luminescence (OSL) and radiocarbon (14C) dates. Three basin-scale geological sections are presented focusing on the architectures and facies of fluvio-deltaic progradations emplaced from 12.9 cal. ka BP to present-day in Lake Saint-Jean. Overlying the bedrock, isolated ice-contact fan deposits are capped by glacimarine muds. Above, fluvio-deltaic and coastal prograding systems were deposited following four major evolutions through time: (i) deltaic systems progressively increased in width, (ii) coastal influence on sedimentation increased, (iii) hydrographic drainage systems became more organised, and (iv) delta graded from steep (Gilbert delta) to low-angle foresets (mouth-bar delta). These evolutions in fluvio-deltaic systems are attributed to the modifications in water discharge, sediment supply and rate of base level fall driven by the deglaciation. The presented succession is considered as representative of the sedimentological signature of fluvial progradations in forced regressive deglacial sequences. Derived from the Lake Saint-Jean basin, this study provides new elements for the recognition and interpretation

    Research in Montreal's St-Jean-de-Dieu Asylum archives has revealed a number of letters from family members and local physicians pleading for asylum care for married women between 1890 and 1921. When added to other admission documents in patients' medical files, these letters allow an intimate glimpse into private lives of families and highlight the pain and distress of dealing with mentally ill people in the home before the introduction of community mental health services. Far from easily abandoning a spouse or mother, close-knit French Canadian families struggled until they could no longer cope before seeking help. To comply with asylum regulations, family members (primarily husbands, who were often illiterate) and local physicians were required to justify their applications for admission, but they did so in different ways.

    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. PMID:15022668

    Lake Saint-Jean is the third largest natural lake in Québec (Canada), however very few studies have focused on the basin-scale limnogeology of this lake. An initial very high-resolution seismic survey of Lake Saint-Jean was conducted in 2011, providing more than 300 km of seismic sections throughout the lake. These seismic profiles permitted the identification of numerous depositional units at a basin-scale (Nutz et al., Boreas 2014). In this contribution, we focus on prominent large-scale, high-energy sedimentary features that are rather atypical in lakes: a sand-prone sedimentary shelf, sediment drifts and extensive erosional surfaces. All of these features may be attributed to wind-driven hydrodynamics affecting the central portion of the lake, at depths well below the wave base. Coupling the seismic profiles with a series of sediment cores and recent dating results, we now can propose a detailed characterization of these sedimentary features including age and context of emplacement, as well as the dominant depositional processes at work. Indeed, a numerical simulation of wind-induced bottom-current distribution based on realistic wind regimes was also applied in order to validate our previous wind-forcing interpretation. This research provides a more thorough understanding of depositional processes at the origin of fine-grained sediment accumulations in lakes. The prevalence of wind-driven processes in some lacustrine depositional systems is also addressed through the presentation of a conceptual depositional model well-suited for high-energy, wind-driven water-bodies. This model is of interest to all geoscientists dealing with present-day lake systems (e.g., reservoir lake management) as well as researchers working with paleo-lacustrine records and strata (e.g., bottom lake anoxia, hiatial surfaces, hydrocarbon exploration).

  8. The raft of the Saint-Jean River, Gaspé (Québec, Canada): A dynamic feature trapping most of the wood transported from the catchment

    The rivers of the Gaspé Peninsula, Québec (Canada), a coastal drainage system of the St. Lawrence River, receive and transport vast quantities of large wood. The rapid rate of channel shifting caused by high-energy flows and noncohesive banks allows wood recruitment that in turn greatly influences river dynamics. The delta of the Saint-Jean River has accumulated wood since 1960, leading to frequent avulsions over that time period. The wood raft there is now more than 3-km in length, which is unusual but natural. This jam configuration allows a unique opportunity to estimate a wood budget at the scale of a long river corridor and to better understand the dynamics of large wood (LW) in rivers. A wood budget includes the evaluation of wood volumes (i) produced by bank erosion (input), (ii) still in transit in the river corridor (deposited on sand bars or channel edges), and (iii) accumulated in the delta (output). The budget is based on an analysis of aerial photos dating back to 1963 as well as surveys carried out in 2010, all of which were used to locate and describe large wood accumulations along a 60-km river section. The main results of this paper show that the raft formation in the delta is dynamic and can be massive, but it is a natural process. Considering the estimated wood volume trapped in the delta from 1963 to 2013 (≈ 25,000 m3), two important points are revealed by the quantification of the wood recruitment volume from 1963 to 2004 (≈ 27,000 m3 ± 400 m3) and of the wood volume stored on the bars in 2010 (≈ 5950 m3). First, the recruitment of large wood from lateral migration for the 40-year period can account for the volume of large wood in the delta and in transit. Second, the excess wood volume produced by lateral migration and avulsion represents a minimum estimation of the large wood trapped on the floodplain owing to wood volume that has decomposed and large wood that exited the river system. Rafts are major trapping structures that provide

    Jean Hamburger (1909–1992) is considered the founder of the concept of medical intensive care (réanimation médicale) and the first to propose the name Nephrology for the branch of medicine dealing with kidney diseases. One of the first kidney grafts in the world (with short-term success), in 1953, and the first dialysis session in France, in 1955, were performed under his guidance. His achievements as a writer were at least comparable: Hamburger was awarded several important literary prizes, including prix Femina, prix Balzac and the Cino del Duca prize (1979), awarded, among others, to Jorge Luis Borges and Konrad Lorenz. Here we would like to offer a selected reading of a “golden” book, “Conseils aux étudiants en medicine de mon service” (“Advice to the Medical Students in my Service”), the first book dedicated to patient-physician relationship in Nephrology, written when dialysis and transplantation were becoming clinical options (1963). The themes include: the central role of the patient, who should be known by name, profession, life style, and not by disease; the importance of the setting of the care; the need for truth-telling and for leaving hope; the role of research not only in the progression of science, but also in the daily clinical practice.

    In November 1883, Jean-Martin Charcot and Charles Féré reported on bone and joint disease of the foot in cases of tabes dorsalis, and referred to the condition as 'pied tabétique'--a disabling neuropathic osteoarthropathy that we usually now refer to as the Charcot foot. Charcot had originally described neuropathic osteoarthropathy in more proximal joints in 1868, and in his 1883 paper with Féré stated that involvement of the short bones and small joints of the foot had not yet been described. They emphasised in the paper that one of their cases was the first ever observed, two years earlier, in 1881. It is relevant, however, that it was in this same year that involvement of the foot by tabetic arthropathy was presented to the International Medical Congress in London by an English surgeon, Herbert William Page. We believe that Page was the first to diagnose and to report a case of tabetic neuropathic osteoarthropathy in which the bones of the foot and ankle were involved. He was also the first to propose a link between the tabetic foot and disease of the peripheral nerves, as opposed to the central nervous system. PMID:23765185

  12. Reduction of forecast uncertainty in the context of hydropower production: a case study for two catchment in Lac-St-Jean, Canada

    This research focuses on the improvement of streamflow forecasts for two subcatchments in the Lac-St-Jean area, a northern part of the province of Quebec in Canada. Those two subcatchments, named Manouane and Passes-Dangereuses, are part of a bigger system, which comprises many reservoirs and six hydropower plants. This system is managed by Rio Tinto Alcan, an aluminium producer who needs this energy for its processes. Optimal management of the hydropower plants highly depends on the reliability of the inflow forecasts to the reservoirs and also on the reliability of observed streamflow. The latter are not directly measured, but rather deduced from the computation of a water balance. This water balance includes streamflow computation based on rating curves for river sections and upstream reservoirs and a modelling process using CEQUEAU hydrological model (Morin et al., 1981). In addition, mostly during the winter, the model has to account for a transfer of water from Lac Manouane reservoir to Passes-Dangereuses through Bonnard channel. Winter flow though Bonnard channel is controlled by a spillway, and represented in CEQUEAU by a transfer function and a fixed time delay (2 days). However, it is suspected that the evacuation function, as it is currently computed, is inaccurate. The main objective of this work is to reduce predictive uncertainty for Lac Manouane and Passes-Dangereuses catchment, for the one-day ahead horizon. This objective is twofold. First, the uncertainty related to the parameterization of the hydrological model had never been evaluated. It was to be investigated whether it is better to spatialize the calibration of the hydrological model. In its actual form, the calibration of the hydrological model CEQUEAU (Morin et al., 1981) is based exclusively on the downstream outflow. There is, however, intermediate streamflow measurements data available for an intermediate location. Our study shows that calibrating the model using streamflows for both

    Hysteria and hypnotism became a favorite topic of studies in the fin de siècle neurology that emerged from the school organized at La Salpêtrière by Jean-Martin Charcot, where he had arrived in 1861. Georges Gilles de la Tourette started working with Charcot in 1884 and probably remained his most faithful student, even after his mentor's death in 1893. This collaboration was particularly intense on 'criminal hypnotism', an issue on which Hippolyte Bernheim and his colleagues from the Nancy School challenged the positions taken by the Salpêtrière School. Bernheim claimed that hypnotism was not a diagnostic feature of hysteria and that there were real-life examples of murders suggested under hypnosis, while hypnosis susceptibility was identified with hysteria by Charcot and Gilles de la Tourette, who saw rape as the only crime associated with hypnotism. The quarrel was particularly virulent during a series of famous criminal cases which took place between 1888 and 1890. At the time, it was considered that La Salpêtrière had succeeded over Nancy, since the role of hypnotism was discarded during these famous trials. However, the theories of Charcot and Gilles de la Tourette were also damaged by the fight, which probably triggered the conceptual evolution leading to Joseph Babinski's revision of hysteria in 1901. Gilles de la Tourette's strong and public interest in hypnotism nearly cost him his life, when a young woman who claimed to have been hypnotized against her will shot him in the head at his own home in 1893. It was subsequently shown that hypnotism had nothing to do with it. The delusional woman was interned at Sainte-Anne for mental disturbance, thus escaping trial. Ironically, Gilles de la Tourette may have been partly responsible, since he had been one of the strongest proponents of placing mentally-ill criminals in asylums instead of prisons. PMID:19602893

    While Alfred Vulpian (1826-1887) is not completely forgotten, he cannot match the uninterrupted celebrity which Jean-Martin Charcot (1825-1893) still enjoys today. After becoming interne (residents) at the same institute in 1848, both were involved in shaping the cradle of what would become modern neurology. Both started work as chiefs at a La Salpêtrière service on January 1, 1862, making common rounds and studies, with several common publications. While their friendship remained 'for life', as stated by Charcot at Vulpian's funeral, their career paths differed. Vulpian progressed quicker and higher, being appointed full professor and elected at the Académie Nationale de Médecine and the Académie des Sciences several years before Charcot, as well as becoming dean of the Paris Faculty of Medicine. These positions also enabled him to support his friend Charcot in getting appointed full clinical professor and becoming the first holder of the chair of Clinique des Maladies du Système Nerveux in 1882. Before studying medicine, Vulpian had worked in physiology with Pierre Flourens, and his career always remained balanced between physiology and neurology, with remarkable papers. He introduced Charcot to optic microscopy during their La Salpêtrière years, indirectly helping him to become his successor to the chair of pathological anatomy in 1872. While Vulpian succeeded so well in local medical affairs, Charcot spent his time building up a huge clinical service and a teaching 'school' at La Salpêtrière, which he never left for over 31 years until his death. This 'school' progressively became synonymous with clinical neurology itself and perpetuated the master's memory for decades. Vulpian never had such support, although Jules Déjerine was his pupil and Joseph Babinski was his interne before becoming Charcot's chef de clinique (chief of staff) in 1885. This unusual switch in Parisian medicine contributed to Charcot's unaltered celebrity over more than a century

    The quality of water and bottom material in the Barataria Preserve of Jean Lafitte National Historical Park and Preserve, Louisiana, was surveyed from March 1999 to May 2000. Organochlorine, chlorophenoxy acid, and organophosphorus pesticides; polychlorinated biphenyls (PCB?s); and trace elements were analyzed in surface water and bottom material from three sites previously sampled in a 1981-82 survey. Surface water at six sites was sampled and analyzed for selected nutrients and major inorganic ions based on their importance to human health, the health of the marshes of the Barataria Preserve, or their usefulness in tracking the circulation of Mississippi River water in the Barataria Preserve. Southern Louisiana was in a moderate to severe drought during most of the sampling period, which elevated salinity in the Barataria Preserve for at least 8 months. Specific conductance values were less than 3,000 ?S/cm (microsiemens per centimeter at 25 degrees Celsius) in surface water throughout the Barataria Preserve from March through September 1999. Specific conductance values increased over the next 2 months and then remained between 5,000 and 6,000 ?S/cm. The herbicide 2,4-D was detected in water at the two sites sampled in August 1999 but not at any site during the two other sampling times. Iron, manganese, and the trace elements copper, nickel, and zinc were detected in dissolved and whole-water samples at all three sites. Nitrite+ nitrate, as nitrogen, concentrations ranged from less than 0.002 to 0.19 mg/L (milligrams per liter). Ammonia, as nitrogen, concentrations ranged from less than 0.01 to 0.16 mg/L. Orthophosphate, as phosphorus, concentrations ranged from less than 0.002 to 0.14 mg/L. Calcium, magnesium, potassium, sulfate, and chloride concentrations in surface water were elevated due to the marine influence on the composition of surface water in the Barataria Preserve during the sampling period. Sulfate and chloride concentrations reached 379 and 2

RJCE determines star-by-star reddening based on a combination of near- and mid-infrared photometry. The new RJCE-generated maps have 2' Multiplication-Sign 2' pixels and span some of the most severely extinguished regions of the Galaxy-those covered with Spitzer/IRAC imaging by the GLIMPSE-I, -II, -3D, and Vela-Carina surveys, from 256 Degree-Sign < l < 65 Degree-Sign and, in general, for |b| {<=} 1 Degree-Sign -1.{sup 0}5 (extending up to |b| {<=} 4 Degree-Sign in the bulge). Using RJCE extinction measurements, we generate dereddened color-magnitude diagrams and, in turn, create maps based on main sequence, red clump, and red giant star tracers, each probing different distances and thereby providing coarse three-dimensional information on the relative placement of dust cloud structures. The maps generated from red giant stars, which reach to {approx}18-20 kpc, probe beyond most of the Milky Way extinction in most directions and provide close to a 'total Galactic extinction' map-at minimum they provide high angular resolution maps of lower limits on A(K{sub s} ). Because these maps are generated directly from measurements of reddening by the very dust being mapped, rather than inferred on the basis of some less direct means, they are likely the most accurate to date for charting in detail the highly patchy differential extinction in the Galactic midplane. We provide downloadable FITS files and an IDL tool for retrieving extinction values for any line of sight within our mapped regions.

    The Geologic Time Scale (GTS) provides the framework for the physical, chemical and biological processes on Earth. The time scale is the tool "par excellence" of the geological trade, and insight in its construction, strength, and limitations enhances its function and its utility. Earth scientists should understand how time scales are constructed and its myriad of physical and abstract data are calibrated, rather than merely using ages plucked from a convenient chart or card. Calibration to linear time of the succession of events recorded in the rocks on Earth has three components: (1) the standard stratigraphic divisions and their correlation in the global rock record, (2) the means of measuring linear time or elapsed durations from the rock record, and (3) the methods of effectively joining the two scales, the stratigraphic one and the linear one. Under the auspices of the International Commission on Stratigraphy (ICS), the international stratigraphic divisions and their correlative events are now largely standardized, especially using the GSSP (Global Stratigraphic Section and Point) concept. The means of measuring linear time or elapsed durations from the rock record are objectives in the EARTH TIME and GTS NEXT projects, that also are educating a new generation of GTS dedicated scientists. The U/Pb, Ar/Ar and orbital tuning methods are intercalibrated, and external error analysis improved. Existing Ar/Ar ages become almost 0.5% older, and U/Pb ages stratigraphically more realistic. The new Os/Re method has potential for directly dating more GSSP's and its correlative events. Such may reduce scaling uncertainty between the sedimentary levels of an age date and that of a stage boundary. Since 1981, six successive Phanerozoic GTS have been published, each new one achieving higher resolution and more users. The next GTS is scheduled for 2011/2012, with over 50 specialists taking part. New chapters include an expanded planetary time scale, sequence stratigraphy, Osmium, Carbon and Oxygen stratigraphy, the Cryogenian period, history of the plants, hominid prehistory, and last but not least the Anthropocene. The Cambrian Period is radically improved with 10 standard stages and detailed trilobite biochronology. Ordovician now has a stable international stages and graptolites scale. The integration of a refined 100 and 400 ka sedimentary cycles scale and a truly high-resolution U/Pb ages scale for the Mississippian is a major step towards the global Carboniferous GTS. The Devonian GTS leaves to be desired with lack of firm definitions for its upper boundary, and the long Emsian stage; it also lacks age dates. Its stages scaling is disputed. The Rhaetian and Norian stages in the Triassic and the Berriasian stage in the Cretaceous urgently require lower boundary definitions, and also boundary age dates. The single ~400 ka eccentricity component is very stable and can extend orbital tuning from the Cenozoic well into the Mesozoic portion of the GTS. Jurassic and Cretaceous now have long orbitally tuned segments. A completely astronomical-tuned Geological Time Scale (AGTS) for the Cenozoic is within reach showing unprecedented accuracy, precision and resolution. Burdigalian in the Miocene, and Lutetian, Bartonian and Priabonian stages in the Eocene still require formal definition. The K/T boundary will become about 0.5 ± 0.1 Ma older. After 25 years of research and authorship in the GTS it behoves me to especially thank my colleagues James Ogg, Frits Agterberg, John McArthur and Roger Cooper for longstanding collaboration. As a final note I urge construction of more regional time scales(like developed ‘down under') calibrated to the standard global GTS, to scale regional rock units.

  7. Jean Piaget: The Old Theory and the New.

    Beilin, Harry

    When Piaget ascribed the origin of knowledge to action, he distanced his theory from most other theories of the origins of mind. As a result, Piaget's conception of mental action has been quite controversial. Piaget's recent, functionalist revisions emphasize procedures and their role in the development of structures. In the new view, structures…

    Dame, Frederick William

    1996-01-01

    Although Rousseau describes in Émile only his scheme for childhood education, he presents us in this work with some direct statements which can be applied to explain more fully the nature of adult education. The author surveys Rousseau's ideas on the role of the general will in adult educational philosophy, subject matter, methodology and negative education, as well as the relationships between the family, student, teacher, community and the state. He concludes that the modern Rousseau would not limit education to males and would recognize that the four Rousseauian periods of educational development — infancy, childhood, youngster, adolescence — is followed by a fifth: adulthood. Adult education is the logical continuation of the four previous phases. Throughout each phase education must permit intellectual and moral growth and always allow for creativity and diversity. Only then can adults become positive contributors to their society.

    2010-05-01

    In this lecture I will discuss three plasma realms, which have attracted my particular attention because of their fascinating observable fine structure and the complex underlying physics. The structure is, of course, owed to the pervading magnetic field. But it is in particular the role of magnetic tensions that will be highlighted. The three plasma phenomena are: (1) cometary plasma tails, where magnetic tensions transfer momentum from the solar wind under mass loading by the comet; (2) auroral arcs, which owe their energy influx to the release of magnetic shear stresses; and (3) solar prominences, in which cool plasma embedded in the hot corona is subject to a balance of magnetic shear stresses and gravity. The last subject is a recent topic of my research and still bears many secrets. Images and movies will be supplemented by brief characterizations of the key physical processes.

    The effect of the dust charge variations on the stability of a self-gravitating dusty plasma has been theoretically investigated. The dispersion relation for the dust-acoustic waves in a self-gravitating dusty plasma is obtained. It is shown that the dust charge variations have significant effects. It increases the growth rate of instability and the instability cutoff wavenumbers. It is found that by increasing the value of the ions temperature and the absolute value of the equilibrium dust charge, the cutoff wavenumber decreases and the stability region is extended.

    Russian neurology was virtually nonexistent in the middle of the 19th century which made a traineeship abroad an absolute necessity. Charcot and his school did not just offer professional training, but created the best minds, which would determine the direction of neurology and psychiatry in Russia for many decades. After returning home, young Russian doctors not only implemented everything they had learned in Western Europe, but proceeded to make their own original contributions. The most talented pupils of Charcot, including such prominent names as Kozhevnikov, Korsakov, Minor, Bekhterev and Darkshevich, became the founders of neurological schools in Russia. They laid the basis for the further development of neurology and psychiatry. Remarkably, though trained by the same teachers, each of these future 'founding fathers' of these neurological and psychiatric schools followed his own individual path which resulted in an undeniable diversity in Russian neurology and psychiatry during the period of their formation.

    Introduction Le pied diabétique se définit comme l'ensemble des manifestations trophiques du pied survenant chez le diabétique par atteinte nerveuse, artérielle et ou infectieuse. Le pied diabétique est un problème majeur de santé publique à l’échelle mondiale avec un taux d'amputation de membres inférieurs très élevé. L’écho-doppler artériel des membres inférieurs est de nos jours incontournable dans la prise en charge du pied diabétique. Le but de cette étude est de montrer la place prépondérante qu'occupe l’écho-doppler artériel dans le bilan lésionnel du pied diabétique. Méthodes Nous avons mené une étude rétrospective monocentrique incluant 46 patients sur une période de 24 mois, de mars 2012 à mars 2014 à l'hôpital Saint-Jean de Dieu, un des deux hôpitaux de référence de la région de Thiès, doté depuis juillet 2011 d'un centre moderne de traitement du diabète et des maladies cardio-métaboliques (Diabcarmet). Dans les critères d'inclusion, nous avons sélectionné tous les patients diabétiques adressés pour un écho-doppler artériel des membres inférieurs dans le cadre d'une prise en charge du pied diabétique. Etaient exclus de l’étude, les patients artéritiques non-diabétiques et les patients diabétiques asymptomatiques référés pour un bilan écho-doppler de routine. Résultats Le sex-ratio était de 1.42 (27 hommes pour 19 femmes). L’âge moyen des patients était de 62,86 ans avec des extrêmes de 23 et 88 ans. 60% des patients (n=28) étaient âgés entre 50 et 70 ans. Le diabète de type 2 était retrouvé chez 95% des patients (n=44) alors que le diabète de type 1 représentait 5% (n=2). La moyenne d’évolution du diabète était estimée à 8 ans, avec des extrêmes de 2 et 20 ans. On notait une atteinte du pied droit chez 24 patients, une atteinte du pied gauche chez 18 patients et une atteinte bilatérale chez 4 patients. La plupart du temps, les lésions du pied diabétique survenaient

  17. Scale-invariance of sediment patterns - the fingerprint of fundamental drivers (Jean Baptiste Lamarck Medal Lecture)

    NASA Astrophysics Data System (ADS)

    Schlager, Wolfgang

    2015-04-01

    In contrast to the realms of magmatism and metamorphism, most depositional processes can be observed directly at the earth's surface. Observation of sediment patterns advanced significantly with the advent of remote sensing and 3D reflection seismics. Remote sensing is particularly relevant for the present topic because it documents mainly Holocene sediments - the best objects to link depositional processes to products. Classic examples of scale-invariant geometry are channel-fan systems, i.e. river-delta and canyon-fan complexes. The underlying control in both instances is the energy-dispersion of a channeled stream of water that discharges in a body of still water. The resulting fan-shaped sediment accumulations are scale-invariant over 7 orders of magnitude in linear size. The Mesozoic-Cenozoic record shows comparable trends and patterns. Further examples of depositional scale-invariance include foresets of non-cohesive sediments and braided-channel deposits. Reefs and carbonate platforms offer an example of scale-invariance related to biotic growth. Shallow-water carbonate platforms rimmed by reefs or reef-rimmed atolls with deep lagoons are characteristic morphologies of tropical carbonate deposits. The structure has been compared to a bucket where stiff reef rims hold a pile of loose sediment. Remote sensing data from the Maldive, Chagos and Laccadive archipelagos of the Indian Ocean show that bucket structures are the dominant depositional pattern from meter-size reefs to archipelagos of hundreds of kilometers in diameter, i.e. over more than 4 orders of magnitude in linear size. Over 2.5 orders of magnitude, the bucket structures qualify as statistical fractals. Ecologic and hydrodynamic studies on modern reefs suggest that the bucket structure is a form of biotic self-organization: The edge position in a reef is favored over the center position because bottom shear is higher and the diffusive boundary layer between reef and water thinner. Thus, the reef edge has easier access to nutrients. Moreover, the edge is less likely to be buried by sediment. The bucket structure is an ecologic response to these conditions. Buckets have been documented from all periods of the Phanerozoic and analogous structures from the late Proterozoic show that the microbial carbonate factory also built buckets. We conclude that a voyage through scales in the sediment realm reveals islands of scale-invariance wherever a single principle dominates the sedimentation process.

  19. Genes and/or jeans?: Genetic and socio-cultural contributions to risk for eating disorders.

    PubMed

    Becker, Anne E; Keel, Pamela; Anderson-Fye, Eileen P; Thomas, Jennifer J

    2004-01-01

    Eating disorders are prevalent among young adult females and pose serious psychological and medical risks. Notwithstanding important advances, efforts to develop effective means of preventing and treating eating disorders have been limited by an incomplete understanding of their multifactorial etiology. Whereas epidemiologic data strongly suggest the influence of socio-cultural context in moderating risk, many hypotheses about how these effects are exerted have remained empirically unevaluated. Specifically, experimental and observational data suggest that social transition (e.g., transnational migration, urbanization, modernization), Western media exposure, and certain peer environments (involving social comparison and teasing) may all contribute to risk. With respect to genetic influences on etiology, family and twin studies have supported a genetic diathesis to eating disorders. Whereas, molecular genetic studies have generated interesting leads- with the most promising findings emerging for genes related to the function of serotonin-they have yet to identify well-replicated susceptibility loci. This paper reviews the data supporting both socio-cultural and genetic contributions for eating disorders and suggests productive future strategies for continuing to unravel their likely multiple and complex interactions.

  20. "Days of future passed" - climate change and carbon cycle history (Jean Baptiste Lamarck Medal Lecture)

    NASA Astrophysics Data System (ADS)

    Weissert, Helmut

    2013-04-01

    With the beginning of the fossil fuel age in the 19th century mankind has become an important geological agent on a global scale. For the first time in human history action of man has an impact on global biogeochemical cycles. Increasing CO2 concentrations will result in a perturbation of global carbon cycling coupled with climate change. Investigations of past changes in carbon cycling and in climate will improve our predictions of future climate. Increasing atmospheric CO2 concentrations will drive climate into a mode of operation, which may resemble climate conditions in the deep geological past. Pliocene climate will give insight into 400ppm world with higher global sea level than today. Doubling of pre-industrial atmospheric CO2 levels will shift the climate system into a state resembling greenhouse climate in the Early Cenozoic or even in the Cretaceous. Carbon isotope geochemistry serves as tool for tracing the pathway of the carbon cycle through geological time. Globally registered negative C-isotope anomalies in the C-isotope record are interpreted as signatures of rapid addition (103 to a few 104 years) of CO2 to the ocean-atmosphere system. Positive C-isotope excursions following negative spikes record the slow post-perturbation recovery of the biosphere at time scales of 105 to 106 years. Duration of C-cycle perturbations in earth history cannot be directly compared with rapid perturbation characterizing the Anthropocene. However, the investigation of greenhouse pulses in the geological past provides insight into different climate states, it allows to identify tipping points in past climate systems and it offers the opportunity to learn about response reactions of the biosphere to rapid changes in global carbon cycling. Sudden injection of massive amounts of carbon dioxide into the atmosphere is recorded in C-isotope record of the Early Cretaceous. The Aptian carbon cycle perturbation triggered changes in temperature and in global hydrological cycling. Changes in physical and chemical oceanography are reflected in widespread black shale deposition ("Oceanic Anoxic Event 1a"), in carbonate platform drowning and in biocalcification crises. "Days of future passed" (Moody Blues, 1967) reminds us that the past provides essential information needed for decisions to be made in the interest of mankind's future.

    Canada strongly believes in the central role to be played by the civil sector in the process leading to the World Food Summit. Dr. Augustine, Member of Parliament of Canada, described how the Canadian Government involved 350 national organizations over an eight-month period in the creation of the country's official position on food security. Canada has also negotiated with several other countries and international organizations on issues such as trade, human rights, the right to food, and follow-up to the Plan of Action. Dr. Augustine summarized Canada's 18 priorities for the World Food Summit. The priorities include human rights and good governance; poverty reduction; peace, security and conflict resolution; national responsibility for food security; national and global partnerships; nutrition and health; human resource development; gender equity; population stabilization; trade liberalization; agricultural adjustment to international markets; post-harvest marketing and food marketing; the role of the private sector; capacity building; environment and sustainable production; and research and technology transfer.

  2. Discovering habitable environments and life in the Saturn System (Jean Dominique Cassini Medal Lecture)

    2015-04-01

    One of the most notable scientific adventures of our time is being conducted jointly by Europe and the United States around the solar system's great ringed planet, Saturn. The Cassini-Huygens mission arrived in orbit in 2004, and the Huygens probe descended through Titan's atmosphere in January 2005. Titan's surface has been found to host a rich and still-enigmatic methane cycle, complete with lakes, seas, rivers and rain. Enceladus is jetting its interior volatiles into space, where the Cassini Orbiter detected and measured a number of species within the resulting plume. These include water, organic molecules, nitrogen compounds, and salts. Cassini radio science detected the presence within both Enceladus and Titan of internal water oceans. Variability with orbital phase of the Enceladus plume, also discovered by the Cassini Orbiter, makes a convincing case for the jets themselves being derived from the deep interior and controlled by tidal forces. Both Enceladus and Titan host potentially habitable environments, and they represent unique opportunities for testing whether either or both of these bodies harbor life. Titan's interior will be difficult to access, but its large surface hydrocarbon seas can be explored in situ with Huygens-like vehicles. The Cassini Orbiter determined the liquid in Titan's seas to be methane and ethane, which raises the question of whether simple chemistry can evolve into autocatalysis and self-replication in a non-aqueous liquid environment. In effect, is there an exotic kind of "life" in the Titan seas? Enceladus is perhaps more straightforward: given that the interior water ocean as expressed through the plume appears to satisfy the formal requirements for habitability, is biological activity occurring there? Answering these questions will require a new generation of robotic vehicles beyond Cassini-Huygens -- and new opportunities for international collaborations in planetary exploration.

    The author is trying to remind us of great role of French culture and French people in spreading the ideas of Enlightenment in Poland. Common use of French language in high societies in 18th century and excellent knowledge of books from Paris created favourite conditions for contacts of Poland with France. The best evidence of common culture of Enlightenment was the Commission of National Education (KEN) and the deep social changes. The direct contacts of French thinkers, writers and scientists with Poland also caused the changes of horizons of aristocracy and gentry. We will remind the main animators of this movement followed A. Jobert. J.E. Gilibert takes a very important place among the animators of Enlightenment. Author intends to present the phases of knowing him, generally mentioning the main conclusions of many research on Gilibert. At the same time author leaves to next speakers a detailed analyze of Gilbert's contribution to the development of Polish science. PMID:26445742

    2009-08-11

    Vibration therapy is currently used in diverse medical specialties ranging from orthopedics to urology to sports medicine. The celebrated 19th-century neurologist, J.-M. Charcot, used vibratory therapy to treat Parkinson disease (PD). This study analyzed printed writings by Charcot and other writers on vibratory therapy and accessed unpublished notes from the Salpêtrière Hospital, Paris. Charcot lectured on several occasions on vibratory therapy and its neurologic applications. He developed a vibration chair for patients with PD after he observed that patients were more comfortable and slept better after a train or carriage ride. He replicated this experience by having patients undergo daily 30-minute sessions in the automated vibratory chair (fauteuil trépidant). His junior colleague, Gilles de la Tourette, extended these observations and developed a helmet that vibrated the head on the premise that the brain responded directly to the pulsations. Although after Charcot's death vibratory therapy was not widely pursued, vibratory appliances are reemerging in 21st century medicine and can be retested using adaptations of Charcot's neurologic protocols.

More than two thousand planets have characterized orbits, for several hundred of them their radii are known. We have discovered an amazing diversity of planetary systems. These observations have revealed the importance of new physical process to be taken into account for the formation and evolution of planetary systems. The synergy between ground-based radial velocity measurements and the detection of transiting planets have permitted exciting possibilities to characterize planets. Already we have the possibility to get clues on the internal composition of exoplanets and their atmosphere. Do we have the instrumental capabilities to detect and study planets as Earth analogues?

  17. Map of risks for the implementation of radio-frequency identification: application of ancillaries in the University Hospital Jean Verdier.

    PubMed

    Bertrand, E; Schlatter, J

    2010-01-01

    Ancillaries are surgical instruments, such as orthopedical instruments set for reconstruction of knee (a mounting arm...) used to implant or extract prosthesis. Their management involves the departments of sterilization and surgery as well as the suppliers. Such a long circuit exposes the instruments to potential risk hazards like a lack of traceability as the suspicion of Creutzfeldt-Jakob. In order to reduce the risk of errors we will propose the implementation of radio-frequency identification (RFID) to trace the ancillaries during each step of the supply chain. The objective of our study is to analyze and to map the risks associated with RFID implementation. A preliminary analysis of risks (APR) is conducted to map out the hazards for the implementation of RFID. The APR identifies 162 scenarios with a maximum risk connected to environment and technology. To reduce the risks identified, 22 courses of action are proposed, such as audits, training, and internal controls. For each action, a procedure has been designed and evaluated. This preliminary analysis of risks allows targeting the potential dangers for the RFID implementation applied to ancillaries and reduces them significantly. PMID:20187581

    This paper makes a fresh analysis of the work of the French alienist J. E. D. Esquirol. In addition to a critical study of his classification of mental diseases, it analyses his main contributions to semiology: the difference between hallucinations and illusions, etc., and it also places the psychiatric clinic into the context of the so-called anatomoclinical mentality.

    May 1, 1958 was an exciting time in the Great Hall of the US National Academy of Sciences. An announcement was made that the Earth possessed radiation belts at high altitudes with intensities thousands of times greater than those of galactic cosmic rays (GCR) that were known to penetrate the atmosphere and produce secondaries detectable at ground level. The leading scientist at the time was James A. Van Allen, head of the Physics Department at the University of Iowa, who instrumented Explorer-1 and follow-on satellites with radiation detectors, and the press labeled the doughnut-shaped structures Van Allen Belts. Once the basic properties of what was subsequently named Earth' s Magnetosphere were established, the quest began to search for Van Allen Belts at other nearby planets, namely Venus and Mars. Mariner 2 was launched to Venus in 1962, but did not have radiation detectors, although a plasma instrument was used to firmly establish the properties of the solar wind. The Mariner 4 mission to Mars was properly instrumented and expectations were high that radiation belts were likely to be present. No planet-associated increase in radiation was measured, however, but use of scaling arguments with Earth' s magnetosphere established an upper limit to the ratio of magnetic moments of MM/ME

    Hospitals in Paris underwent considerable change at the end of the 19th century. As they moved from providing accommodation to care, their mission shifted from helping to healing. The glorification of scientific progress, as opposed to religious obscurantism, affected all of French 'Republican' society, in particular a significant part of the medical profession, led by figures such as D.M. Bourneville, former interne (house officer) under J.M. Charcot and also his publisher. Bourneville helped bring about the creation of nursing schools and the gradual replacement of religious orders by educated secular nurses. Marguerite Bottard, Charcot's chief nurse made famous by A. Brouillet's painting 'Une leçon clinique à La Salpêtrière', would be glorified and decorated as a model for this movement. A letter by G. Gilles de la Tourette to Charcot's successor F. Raymond, never before published, illustrates this progressive current of thought and revisits the struggle to secularise hospitals under the Third Republic in France. At the same time, it renews interest in the exemplary career of a nurse whose name was recently given to a building at La Salpêtrière Hospital. PMID:21487229

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

  10. High-resolution facies analysis and sequence stratigraphy of fluvio-deltaic depositional systems in tectonically-active basins (Jean Baptiste Lamarck Medal)

    NASA Astrophysics Data System (ADS)

    Mutti, E.

    2012-04-01

    In ancient tectonically-active basins fed by relatively small and high-gradient rivers, both marine and lacustrine fluvio-deltaic systems display similar vertical stacking patterns which are primarily controlled by high-frequency variations of sediment flux to the basin. These variations are superimposed over higher-order cycles of tectonic uplift and relative quiescence recorded by changes in the source areas, basin configuration and overall style of sedimentation.Spectacular examples of these cyclically stacked successions crop out in the upper Cretaceous and Paleogene deposits of the south-central Pyrenean foreland basin. Similar stacking patterns are also common in other basins (e.g., the Jurassic-Cretaceous Nequen basin, Argentina and the Tertiary Piedmont Basin, northwestern Italy). Sediment flux to the sea controls the high-frequency stacking pattern of ancient fluvio-deltaic depositional systems through cyclic variations in flow efficiency which is mainly a function of the magnitude and sediment concentration of river outflows during floods. These variations result in periods of inertia- and friction-dominated jet flows followed by periods during which fluvial activity dramatically decreases. These cyclic variations, which are ultimately controlled by climate and baselevelchanges (Milankowitch cycles), are recorded by m- to dam-thick facies successions that can be interpreted as the basic "building block" (in sequence-stratigraphic parlance) of larger-scale depositional sequences. Inertia-dominated periods are characterized by large-volume highly erosive hyperpycnal flows typically containing abundant skeletal debris and mudstone clasts. These flows bypass river mouths and carry sand tonearshore and shelfal regions forming m-thick packets of tabular graded sandstone beds with HCS alternating with muddier facies. These sandstones, which extend up to several km in shelfal regions and grade distally into prodeltaic sediments, are a typical and volumetrically dominant deltaic element herein referred to as "flood-generated delta-front sandstone lobes". Their facies tracts closely resemble those observed in deep-water turbidites. Unfortunately, because of the presence of HCS, these shallow-marine sediment gravity flow deposits have been and are still commonly mistaken in most literature for "storm-dominated" shoreface deposits. Friction-dominated periods are expressed by mouth-bar progradation produced by river outflows of limited volume and efficiency that dissipate their energy at river mouths and are thus able to carry seaward only their fine-grained sediment load through buoyant plumes and dilute hyperpycnal flows. When rivers dramatically decrease their activity, fluvio-deltaic systems aggrade through marine mudstone facies that pass landward into flood-plain mudstones with paleosols. Marine diffusion processes are restricted to local tidal reworking that occurs in river mouth regions and, more extensively, in large estuaries where fluvial processes mix with strong tidal action during early periods of base-level rise. Following decreased river activity, carbonate deposition may locally occur forming generally thin units at the top of fluvio-deltaic sandstones. Several problems arise as to the sequence stratigraphic interpretation of these fluvio-deltaic systems and their cyclic stacking patterns. In particular, these problems concern the significance of the "shoreface" and "parasequence" concepts that can be misleading if not viewed within a robust framework of stratigraphic and faciesconstraints.

    The text of the Anatomical Institutions of Johann Guinter von Andernach, in its original version, was published almost simultaneously in Paris and Basel in 1536. Guinter was then in his fiftieth year, and Andreas Vesalius who was his student in Paris between 1533 ans 1536, was only twenty-two years old. His studies being finished in Leuven and his thesis being published for the first edition in Leuven in February 1537, and for the second in Basel in March 1537, Vesalius went to Padua where he was named professor of anatomy and surgery. Vesalius, besides the reasons put forward in his dedicatory lettre to Johann Armenterianus, tried to have rapidly printed documents for his students. He published in this way in April 1538 the engraved version of the great plates which he had mostly drawn and used to support his demonstrations during sessions of dissection. For the accompanying text, he choosed the handbook of his Master Guinter von Andernach which he decided to edit incorporating modifications and which he published in Venice in 1538 by D. Bernardinus. The modifications made by Vesalius on the Guinter's text can be classified in several headings: minor adjustments, additions of anatomical comments, additions corroborating traditional physiology, and anecdotes peppering the text.

    Anthropogenic activities are today one of the major factors controlling the evolution of our environment with major consequences on all Earth surface compartments: atmosphere, oceans, continents and biosphere. Such consequences accelerated with the industrial revolution, but probably started much earlier as they are related to the demographic evolution and the settlement of various human communities during the last millennia. They are presently reaching unequal effects all over the globe.

  13. The Mediterranean Plio-Pleistocene: A reference frame for astronomically paced low and high latitude climate changes (Jean Baptiste Lamarck Medal Lecture)

    NASA Astrophysics Data System (ADS)

    Lourens, Lucas

    2016-04-01

    The astronomical theory of climate has revolutionized our understanding of past climate change and the development of highly accurate geologic time scales for the entire Cenozoic. Most of this understanding has started with the construction of high-resolution stable oxygen isotope (18O) records from planktonic and benthic foraminifera of open ocean deep marine sediments explored by the international drilling operations of DSDP, ODP and IODP. These efforts culminated into global ocean isotopic stacked records, which give a clear picture of the evolution of the climate state through time. Fundamental for these reconstructions are the assumptions made between the astronomical forcing and the tuned time series and the accuracy of the astronomical solution. In the past decades, an astronomically calibrated time scale for the Pliocene and Pleistocene of the Mediterranean has been developed, which has become the reference for the standard Geologic Time Scale. Characteristic of the studied marine sediments are the cyclic lithological alternations, reflecting the interference between obliquity and precession-paced low latitude climate variability. These interference patterns allowed to evaluate the accuracy of astronomical solutions and to constrain the dynamical ellipticity of the Earth and tidal dissipation by the Sun and the Moon, which in turn provided the backbone for the widely applied LR04 open ocean benthic isotope stack of the past 5 Myr. So far, the assumed time lags between orbital forcing and the global climate response as reflected in LR04 have not been tested, while these assumptions hark back to SPECMAP, using simple ice sheet models and a limited number of radiometric dates. In addition, LR04 adopted a shorter response time for the smaller ice caps during the Pliocene. Here I present the first benthic 18O record of the Mediterranean reference scale, which strikingly mirrors the LR04. I will use this record to discuss the assumed phase relations and its potential to constrain global sea level changes and their cause over the past 5.3 million years.

    A Gram-stain-negative heterotrophic bacterium, designated GSD6(T), capable of growth on aliphatic hydrocarbons as a sole carbon and energy source, was isolated from sea-tidal flat sediment of the Yellow Sea, South Korea. Cells were facultatively aerobic, catalase- and oxidase-positive, motile rods with a single polar flagellum. Growth of strain GSD6(T) was observed at 4-37 °C (optimum 30 °C), at pH 5.5-9.0 (optimum pH 6.5-7.5) and in the presence of 1-9% (w/v) NaCl (optimum 2%). Strain GSD6(T) contained ubiquinone-8 (Q-8) as the sole isoprenoid quinone and summed feature 3 (comprising C16 : 1ω7c and/or iso-C15 : 0 2-OH), C16 : 0, C18 : 1ω7c, C17  : 0 10-methyl and C17 : 1ω8c as the major fatty acids. Phosphatidylethanolamine and phosphatidylglycerol were identified as the major polar lipids. The G+C content of the genomic DNA was 44.6 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain GSD6(T) formed a phylogenetic lineage with members of the genus Aliiglaciecola . Strain GSD6(T) was most closely related to Aliiglaciecola lipolytica E3(T) with a 16S rRNA gene sequence similarity of 97.4%, but their DNA-DNA hybridization value was 39.1 ± 7.1%. On the basis of phenotypic, chemotaxonomic and molecular features, strain GSD6(T) represents a novel species of the genus Aliiglaciecola , for which the name Aliiglaciecola aliphaticivorans sp. nov. is proposed. The type strain is GSD6(T) ( =KACC 18129(T) =JCM 30133(T)). An emended description of the genus Aliiglaciecola is also proposed. PMID:25713045

  17. Reflections on the use of the concept of plasticity in neurobiology. Translation and adaptation by Bruno Will, John Dalrymple-Alford, Mathieu Wolff and Jean-Christophe Cassel from J. Paillard, J Psychol 1976;1:33-47.

    2008-09-01

    After having underlined the ambiguities of the concept of plasticity and the dangers of its purely metaphoric use in neurobiology, it is suggested that we return to a more precise definition of the structure, the operating principles and the function of the "systemic" unit or "integron" relevant to the particular level of analysis in question. Any change can then be described as a modification of function, a change in the operation principles, or an alteration of the material structure of the system. It is suggested that the term plastic should be restricted to describing, among the possible variations in the operating principles or the function of a given system, any lasting alteration of the connectivity network of the system under the influence of an external force or environmental constraint. Therefore, systematic or random variations of performance, functional flexibility or the vicarious(1) processes or strategies that can be found in a rigidly wired system are not justified examples of plasticity.

  20. Scalar excitation with Leggett frequency in 3He -B and the 125 GeV Higgs particle in top quark condensation models as pseudo-Goldstone bosons

    NASA Astrophysics Data System (ADS)

    Volovik, G. E.; Zubkov, M. A.

    2015-09-01

    We consider the scenario in which the light Higgs scalar boson appears as the pseudo-Goldstone boson. We discuss examples in both condensed matter and relativistic field theory. In 3He -B the symmetry breaking gives rise to four Nambu-Goldstone (NG) modes and 14 Higgs modes. At lower energy one of the four NG modes becomes the Higgs boson with a small mass. This is the mode measured in experiments with the longitudinal NMR, and the Higgs mass corresponds to the Leggett frequency MH=ℏΩB . The formation of the Higgs mass is the result of the violation of the hidden spin-orbit symmetry at low energy. In this scenario the symmetry-breaking energy scale Δ (the gap in the fermionic spectrum) and the Higgs mass scale MH are highly separated: MH≪Δ . On the particle physics side we consider the model inspired by the models of Refs. Cheng et al. [J. High Energy Phys. 08 (014) 095] and Fukano et al. [Phys. Rev. D 90, 055009 (2014)]. At high energies the SU(3) symmetry is assumed which relates the left-handed top and bottom quarks to the additional fermion χL. This symmetry is softly broken at low energies. As a result the only C P -even Goldstone boson acquires a mass and may be considered as a candidate for the 125 GeV scalar boson. We consider a condensation pattern different from that typically used in top-seesaw models, where the condensate ⟨t¯ LχR⟩ is off-diagonal. In our case the condensates are mostly diagonal. Unlike the work of Cheng et al. [J. High Energy Phys. 08 (014) 095] and Fukano et al. [Phys. Rev. D 90, 055009 (2014)], the explicit mass terms are absent and the soft breaking of SU(3) symmetry is given solely by the four-fermion terms. This reveals a complete analogy with 3He, where there is no explicit mass term and the spin-orbit interaction has the form of the four-fermion interaction.

  4. Relationship between Aeolian tone and Wake Vortex from Inclined Flat Blade

    NASA Astrophysics Data System (ADS)

    Yoshitake, Sho; Hayashi, Hidechito; Sasaki, Souichi; Fukano, Tohru

    The three dimensional structure of the wake vortex was investigated in relating to the aeolian tone from the inclined blade. It was pointed out that the aeolian tone is largest not at zero, but at ten degree of the inclined angle. The correlation length of the wake vortex in span becomes large at small inclined angles. The large scale structures of the wake vortex are generated in zero and ten degree of inclined angle. The shape of the structure is influenced with the span-wise velocity in the dead air region. There are small scale spots of the pressure fluctuation at the trailing edge. The spots are interacted each other and make a large cluster of the pressure fluctuation. It is proposed that the scale of it is decided by the timing of the wake vortex formation. And the shape of the wake vortex structure is closely related with the scale of it. The correlation length of the wake vortex is calculated from the shape of the structure. The estimation of aeolian tone by using the length with Fukano's model is well coincided to experiments.

    Year 2006 has been marked in France by the vote in the Parliament of the Planning Act of 28 June, 2006, concerning the sustainable management of radioactive materials and waste. This vote was the achievement of a 15 years research programme performed as required by the previous Research Law of 1991, also known as the Bataille Law, from the name of Christian Bataille, MP, who drafted it and monitored its enforcement as a member of the Parliamentary Office for Scientific and Technological Assessment (Office Parlementaire d'Evaluation des Choix Scientifiques et Techniques - OPECST). At that time a stepwise approach to siting was introduced in the process. It included the study of several alternatives to the geological disposal of long lived high level radioactive waste. Those alternatives have been thoroughly studied and assessed before the Government decided to submit the bill to the Parliament. Experience has been gained not only on the scientific and technical aspects, but also in the field of decision making process, also called now governance. However, not only the results of the research programme were decisive in preparing the bill, but also of major importance were the industrial experience of ANDRA and the rigorous programme management along all those years. Main lessons learnt from the experience are given in this paper. (authors)

    Mercer, Erin; Conway, Nicki; Flynn, Jennifer; Mercer, Chris

    2008-01-01

    Purpose: This study investigated perceptions of patients regarding physiotherapists’ attire. Methods: Three hundred patients in three publicly funded outpatient physiotherapy clinics were asked to complete a questionnaire, ranking four photographed modes of attire (lab coat, tailored dress, “scrubs,” and jeans) in terms of professionalism, preference, and appropriateness and rating their level of agreement with four statements about physiotherapists’ attire. Results: Response rate was 63.7 %. The lab coat was ranked most professional, tailored dress most preferred, and jeans least professional and least preferred. Although jeans were deemed inappropriate (p < 0.001), strong support was shown for wearing jeans on “casual day” (p = 0.001). Age of respondents influenced the perception of the appropriateness of wearing jeans (p = 0.007 for male therapist; p = 0.017 for female therapist); only the cohort <36 years considered jeans appropriate apparel. Overall exposure to physiotherapists (number of lifetime visits) affected patients’ perceptions of the importance of attire (p = 0.039) and the appropriateness of wearing jeans (p = 0.018): as number of visits increased, perceived importance decreased and perceived propriety of jeans increased. Conclusion: The findings of this study, the first to examine patients’ opinions of physiotherapists’ attire, suggest that outpatients made clear distinctions between what they perceived as professional and what they preferred, as well as between the appropriateness of physiotherapists’ wearing jeans in general and the appropriateness of their doing so on “casual day.” Age and exposure to physiotherapists influenced patients’ perceptions of attire.

It is suggested that various types of excess, such as excess of excitation (Freud), the excess of the other (Laplanche), excess beyond symbolization and the excess of the forbidden object of desire (Leviticus; Lacan) work synergistically to constitute the compelling power of sexuality. In addition to these notions, further notions of excess touch on its transformative potential. Such notions address excess that shatters psychic structures and that is actively sought so as to enable new ones to evolve (Bersani). Work is quoted that regards excess as a way of dealing with our lonely, discontinuous being by using the "excessive" cosmic energy circulating through us to achieve continuity against death (Bataille). Two contemporary analytic thinkers are engaged who deal with the object-relational and intersubjective vicissitudes of excess. PMID:18430702

  1. Self-gravitational instability in magnetized finitely conducting viscoelastic fluid

    NASA Astrophysics Data System (ADS)

    Prajapati, R. P.; Chhajlani, R. K.

    2013-04-01

    The linear self-gravitational instability of finitely conducting, magnetized viscoelastic fluid is investigated using the modified generalized hydrodynamic (GH) model. A general dispersion relation is obtained with the help of linearized perturbation equations using the normal mode analysis and it is discussed for longitudinal and transverse modes of propagation. In longitudinal propagation, we find that Alfven mode is uncoupled with the gravitating mode. The Jeans criterion of instability is determined which depends upon shear viscosity and bulk viscosity while it is independent of magnetic field. The viscoelastic effects modify the fundamental Jeans criterion of gravitational instability. In transverse mode of propagation, the Alfven mode couples with the acoustic mode, compressional viscoelastic mode and gravitating mode. The growth rate of Jeans instability is compared in weakly coupled plasma (WCP) and strongly coupled plasma (SCP) which is larger for SCP in both the modes of propagations. The presence of finite electrical resistivity removes the effect of magnetic field in the condition of Jeans instability and expression of critical Jeans wavenumber. It is found that Mach number and shear viscosity has stabilizing while finite electrical resistivity has destabilizing influence on the growth rate of Jeans instability.

  2. Gravitational Instability of Rotating, Pressure-confined, Polytropic Gas Disks with Vertical Stratification

    NASA Astrophysics Data System (ADS)

    Kim, Jeong-Gyu; Kim, Woong-Tae; Seo, Young Min; Hong, Seung Soo

    2012-12-01

    We investigate the gravitational instability (GI) of rotating, vertically stratified, pressure-confined, polytropic gas disks using a linear stability analysis as well as analytic approximations. The disks are initially in vertical hydrostatic equilibrium and bounded by a constant external pressure. We find that the GI of a pressure-confined disk is in general a mixed mode of the conventional Jeans and distortional instabilities, and is thus an unstable version of acoustic-surface-gravity waves. The Jeans mode dominates in weakly confined disks or disks with rigid boundaries. On the other hand, when the disk has free boundaries and is strongly pressure confined, the mixed GI is dominated by the distortional mode that is surface-gravity waves driven unstable under their own gravity and thus incompressible. We demonstrate that the Jeans mode is gravity-modified acoustic waves rather than inertial waves and that inertial waves are almost unaffected by self-gravity. We derive an analytic expression for the effective sound speed c eff of acoustic-surface-gravity waves. We also find expressions for the gravity reduction factors relative to a razor-thin counterpart that are appropriate for the Jeans and distortional modes. The usual razor-thin dispersion relation, after correcting for c eff and the reduction factors, closely matches the numerical results obtained by solving a full set of linearized equations. The effective sound speed generalizes the Toomre stability parameter of the Jeans mode to allow for the mixed GI of vertically stratified, pressure-confined disks.

    Clothing can either retard or accelerate dermal exposure to phthalates. To investigate the impact of clothing on dermal exposure to six phthalates (DMP/DEP/DiBP/DnBP/BBzP/DEHP) in real environments, two sets of experiments have been conducted: (1) Skin wipes were collected from 11 adults to examine the phthalate levels on both bare-skin (hand/forehead) and clothing-covered body locations (arm/back/calf); (2) Five adults were asked to wear just-washed jeans for 1 day (1(st) experiment), 5 days (2(nd) experiment), and 10 days (3(rd) experiment). Phthalate levels on their legs were measured on selected days during the wearing period, and phthalate levels in the jeans were measured at the end of each experiment and again after washing. Measured phthalate levels on body locations covered by clothing were lower than those on uncovered locations, but still substantial. Dermal uptake would be underestimated by a factor of 2 to 5 if absorption through body locations covered by clothing were neglected. Phthalate levels in the jeans and on the legs increased with the wearing time. However, the levels in the jeans and on the legs were not strongly correlated, indicating that other pathways, e.g, contact with bedding or bedclothes, likely contribute to the levels on the legs. The efficiency with which laundering washing removed phthalates from the jeans increased with decreasing Kow; median values ranged from very low (<5%) for DEHP to very high (∼75%) for DMP.

  4. Comparative Study Of Focal Mechanisms In South Central Chile Before And After The 2010 Maule Earthquake

    NASA Astrophysics Data System (ADS)

    Agurto, H.; Rietbrock, A.; Ryder, I. M.; Haberland, C. A.

    2011-12-01

    On 27 February 2010, a Mw=8.8 earthquake occurred off the coast of south central Chile rupturing nearly 500 km of the subduction zone plate interface. The earthquake also generated a tsunami and caused more than 500 fatalities. The largest earthquakes recorded have taken place along subduction margins (e.g. Chile 1960, 2010, Andaman-Sumatra 2004, Japan 2011) and understanding their rupture mechanisms and deformation regimes is therefore of vital importance. From November 2004 to October 2005, the TIPTEQ project ("From The Incoming Plate to megaThrust EarthQuake"; Rietbrock et al., 2007; Haberland et al., 2009) maintained a network of 120 seismic stations inland and 10 stations at sea between 37 and 39° lat. S., continuously-recording and monitoring the seismicity occurring in the area before the 2010 Maule earthquake. By using first motion polarities and moment tensor inversion we have computed and analyzed focal mechanisms for a subset of data from these records. We found thrust faulting along the subduction interface down to a depth of ~30 km, followed by a gap in the seismicity and then deeper earthquakes showing diverse faulting mechanisms more sparsely distributed within the subducting plate. We also see strike-slip crustal faulting occurring down to ~12 km depth within the area of the Lanalhue fault. The most striking observation is the presence of deep (40 km) normal faulting seismicity in the fore-arc, close to the trench. We have now started to analyze the International Maule Aftershocks Dataset (IMAD) of the 2010 earthquake in the southern rupture region. Again we observe thrust faulting in the subduction interface and a seismic gap between an upper and lower zone of seismicity along the interface. By comparison of the pre- and post-earthquake datasets we are investigating whether the Maule earthquake caused any changes in the style of deformation in this part of Chile.

    Anatomical knowledge of rectum and its fascial relationship is crucial in modem surgery and it represents the basis of total mesorectal excision. Most of the contemporary authors make reference to Waldeyer's description and use the name fascia propria recti. However, there are evidence regarding Thomas Jonnesco's priority in describing this fascial structure 5 years before Waldeyer. Thomas Jonnesco's description was published in a famous anatomy textbook: Traité d'Anatomie Humaine, Paris, Bataille, 1894, editor P. Poirier, where Thomas Jonnesco was the author of volume 4, fascicule 1, containing the anatomy of the digestive system. His description of the rectum sheath precedes Waldeyer's publication (Das Becken, Cohen, Bonn, 1899). The description of the rectum sheath is included also into the second edition of Traité d'Anatomie Humaine (editors P. Poirier and A. Charpy) published again in 1901 at Masson Publishing House. This second version, better known by contemporary authors (Chapuis et al. Dis Colon Rectum 2002;45:1), probably revised by Charpy, is no more so simple and so clear as the first one. In our paper Thomas Jonnesco's original description of rectal fascia (rectum sheath), published in 1894, is facsimiled, the two succesive editions of the book are compared and a comparison with Waldeyer's description of fascia propria recti is done. The priority of Thomas Jonnesco seems to be well proved. In this respect our own research is in line with the observations of Chapuis and Bell si colab. PMID:20726295

  8. Wind and Rotation Enhanced Escape From the Early Terrestrial Atmospheres

    NASA Astrophysics Data System (ADS)

    Hartle, R. E.

    2001-05-01

    The earliest atmospheres of the terrestrial planets are thought to have been hotter, have stronger winds and rotate faster than atmospheres of today. Since these primitive atmospheres were weakly bound, they evolved rapidly because atmospheric escape was very strong, often referred to as "blowoff." Such escape has been treated as hydrodynamic, transonic flow, similar to solar wind flow dynamics. However, in many cases the outward flow is hydrodynamic at low altitudes only to become collisionless at higher altitudes, well before sonic speeds are ever attained. Recent models dealing with such transition from fluid to kinetic flow have applied the Jeans escape flux at the exobase. This approach has lead to escape rates that are too low due to the fact that thermospheric winds and planetary rotation increase escape fluxes considerably over the corresponding Jeans fluxes (1). In particular, for a given density and temperature at the exobase, the escape flux increases as the wind speed and/or the rotation rate increase. Also, for a given wind speed and rotation rate, the escape flux enhancement over the Jeans flux increases as the mass of an escaping constituent increases, an important factor in isotope fractionation, especially the enrichment of deuterium on Mars. Accounting for a range of possible temperatures, thermospheric wind speeds and planetary rotation rates in the primitive atmospheres of the terrestrial planets, estimates are made of light constituent escape flux increases over the corresponding Jeans fluxes.

  9. Dynamical Effects On The Escape of H and D: Martian Water Reservoirs

    NASA Astrophysics Data System (ADS)

    Hartle, R.

    The evolution of water on Mars is dependent on the loss rates of H and D from its atmosphere, where the dominant loss mechanism for these constituents is Jeans es- cape. Throughout time, preferential escape of H over D has produced a deuterium rich atmosphere with a D/H ratio 5.2 times that of terrestrial water. Motion in the atmo- sphere of Mars is shown to change the Jeans escape rates of H and D in two important ways: (1) Atmospheric wind and rotation at the exobase increase the escape fluxes of H and D above the corresponding Jeans fluxes. (2) The percentage increase in escape flux due to motion is greatest for D. Recently, several models have been used to esti- mate the magnitudes of current and ancient crustal water reservoirs on Mars that freely exchange with its atmosphere. Differences in the reservoir sizes are influenced by dif- ferences in the composition at the exobase, thermal history of the atmosphere and the D/H ratio of earlier epochs as inferred from meteorites. When motion enhanced Jeans escape is applied to each of these models, it is shown in every case that factors (1) and (2) above lead to current and ancient crustal water reservoirs that are larger than those obtained without motion.

  8. Wind and Rotation Enhanced Escape from the Early Terrestrial Atmospheres

    NASA Technical Reports Server (NTRS)

    Hartle, Richard E.; Einaudi, Franco (Technical Monitor)

    2001-01-01

    The earliest atmospheres of the terrestrial planets are thought to have been hotter, have stronger winds and rotate faster than atmospheres of today. Since these primitive atmospheres were weakly bound, they evolved rapidly because atmospheric escape was very strong, often referred to as "blowoff." Such escape has been treated as hydrodynamic, transonic flow; similar to solar wind flow dynamics. However, in many cases, although the outward flow is hydrodynamic at low altitudes, it becomes collisionless at higher altitudes, before sonic speeds are ever attained. Recent models dealing with the transition from fluid to kinetic flow have applied the Jeans escape flux at the exobase. This approach leads to escape rates that are too low, because thermospheric winds and planetary rotation are known to increase the escape flux above the corresponding Jeans flux. In particular, for a given density and temperature at the exobase, the escape flux increases as the wind speed and/or the rotation rate increase. Also, for a given wind speed and rotation rate, the escape flux enhancement over the Jeans flux increases as the mass of an escaping constituent increases, an important factor in isotope fractionation, especially the enrichment of deuterium on Mars. Accounting for a range of possible temperatures, thermospheric wind speeds and planetary rotation rates in the primitive atmospheres of the terrestrial planets, estimates are made of light constituent escape flux increases over the corresponding Jeans fluxes.

  15. The correlation function for density perturbations in an expanding universe. I - Linear theory

    NASA Technical Reports Server (NTRS)

    Mcclelland, J.; Silk, J.

    1977-01-01

    The evolution of the two-point correlation function for adiabatic density perturbations in the early universe is studied. Analytical solutions are obtained for the evolution of linearized spherically symmetric adiabatic density perturbations and the two-point correlation function for these perturbations in the radiation-dominated portion of the early universe. The results are then extended to the regime after decoupling. It is found that: (1) adiabatic spherically symmetric perturbations comparable in scale with the maximum Jeans length would survive the radiation-dominated regime; (2) irregular fluctuations are smoothed out up to the scale of the maximum Jeans length in the radiation era, but regular fluctuations might survive on smaller scales; (3) in general, the only surviving structures for irregularly shaped adiabatic density perturbations of arbitrary but finite scale in the radiation regime are the size of or larger than the maximum Jeans length in that regime; (4) infinite plane waves with a wavelength smaller than the maximum Jeans length but larger than the critical dissipative damping scale could survive the radiation regime; and (5) black holes would also survive the radiation regime and might accrete sufficient mass after decoupling to nucleate the formation of galaxies.

  18. Separating the Universe into real and fake energy densities

    NASA Astrophysics Data System (ADS)

    Hu, Wayne; Chiang, Chi-Ting; Li, Yin; LoVerde, Marilena

    2016-07-01

    The separate universe technique provides a means of establishing consistency relations between short-wavelength observables and the long-wavelength matter density fluctuations within which they evolve by absorbing the latter into the cosmological background. We extend it to cases where nongravitational forces introduce a Jeans scale in other species like dynamical dark energy or massive neutrinos. The technique matches the synchronous gauge matter density fluctuations to the local expansion using the acceleration equation and accounts for the temporal nonlocality and scale dependence of the long-wavelength response of small scale matter observables, e.g., the nonlinear power spectrum, halo abundance and the implied halo bias, and N -point correlation functions. Above the Jeans scale, the local Friedmann equation relates the expansion to real energy densities and a curvature that is constant in comoving coordinates. Below the Jeans scale, the curvature evolves and acts like a fake density component. In all cases, the matter evolution on small scales is correctly modeled as we illustrate using scalar field dark energy with adiabatic or isocurvature initial conditions across the Jeans scale set by its finite sound speed.
