    2016-01-01

    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.

  7. 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.

  8. Interview With Jean Laplanche.

    PubMed

    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).

    2010-12-01

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

  16. Why does the Jeans Swindle work?

    Falco, M.; Hansen, S. H.; Wojtak, R.; Mamon, G. A.

    2013-04-01

    When measuring the mass profile of any given cosmological structure through internal kinematics, the distant background density is always ignored. This trick is often referred to as the `Jeans Swindle'. Without this trick a divergent term from the background density renders the mass profile undefined; however, this trick has no formal justification. We show that when one includes the expansion of the Universe in the Jeans equation, a term appears which exactly cancels the divergent term from the background. We thereby establish a formal justification for using the Jeans Swindle.

  20. Jeans' gravitational instability and nonextensive kinetic theory

    E-print Network

    J. A. S. Lima; R. Silva; J. Santos

    2002-11-19

    The concept of Jeans gravitational instability is rediscussed in the framework of nonextensive statistics and its associated kinetic theory. A simple analytical formula generalizing the Jeans criterion is derived by assuming that the unperturbed self- gravitating collisionless gas is kinetically described by the $q$-parameterized class of power law velocity distributions. It is found that the critical values of wavelength and mass depend explicitly on the nonextensive $q$-parameter. The standard Jeans wavelength derived for a Maxwellian distribution is recovered in the limiting case $q$=1. For power-law distributions with cutoff, the instability condition is weakened with the system becoming unstable even for wavelengths of the disturbance smaller than the standard Jeans length $\\lambda_J$.

    PubMed

    Cordier, Jean-François

    2011-06-01

    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

One very special instrument of this type was the ``heliometer with unequal focal lengths'' designed by the Belgian astronomer Jean-Charles Houzeau for the 1882 transit of Venus. 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.

  15. Jeans Analysis of Bok globules in $f(R)$ gravity

    We examine the effects of f(R) gravity on Jeans analysis of collapsing dust clouds. We find the presence of f(R) gravity modifies the limit for collapse. In this analysis we add perturbations to a de Sitter background. Depending on the characteristics f(R), the appearance of new limits is possible. The physicality of these limits is examined. We find the asymptotic Jeans masses for f(R) theories compared to standard Jeans mass. The effects of the f(R) modified Jeans mass for viable theories are examined in molecular clouds. Bok globules have a mass range comparable to Jeans masses in question and are therefore used for comparing different f(R) models. Viable theories are found to assist in star formation.

  11. Jean-Martin Charcot and his legacy.

    PubMed

    Bogousslavsky, Julien

    2014-01-01

    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.

    2015-08-01

    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.

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

    SciTech Connect

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

    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.

    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.

    The Jeans instability in self-gravitating plasma with Kappa distributed dust grains is investigated basing on assumption that the mutual interaction among dust grains is governed by Lennard-Jones potential. It is shown that the presence of additional suprathermal particles has significant effects on the range of unstable modes and growth rate of Jeans instability. Compared with Maxwellian scenario, suprathermality stabilized the Jeans instability.

  15. Sir James Jeans and the Stability of Gaseous Stars

    In 1925 Sir James Jeans calculated that a star made up of an ideal gas, generating energy as a moderately positive function of temperature and density, could not exist. Such stars would be unstable to oscillations of increasing size. It appears that the flaw in his calculation has never been clearly explained, especially the physical basis for it. I conclude it lies in an almost offhand assumption made about the form of the temperature perturbation. The episode has lessons concerning the structure of stars, the use of perturbation methods (especially in discussing stability), the use of mathematical models and the process by which one theory is chosen over its competitors.

    In this article, I use a new book about Jean Piaget to introduce a new historical method: examining "psychological factories." I also discuss some of the ways that "Great Men" are presented in the literature, as well as opportunities for new projects if one approaches the history of the discipline differently and examines the conditions that made that greatness possible. To that end, the article includes many details about Piaget that have never before been discussed in English. Attention is drawn, in particular, to Piaget's collaborators: the hundreds of workers at his factory in Geneva, many of whom were women. (PsycINFO Database Record (c) 2012 APA, all rights reserved).

    Akbari-Moghanjoughi, M.

    2014-08-15

    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.

    2014-03-15

    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.

    The Jeans instability of self-gravitating quantum plasma is examined considering the effects of viscosity, finite Larmor radius (FLR) corrections and rotation. The analysis is done by normal mode analysis theory with the help of relevant linearized perturbation equations of the problem. The general dispersion relation is obtained using the quantum magneto hydrodynamic model. The modified condition of Jeans instability is obtained and the numerical calculations have been performed to show the effects of various parameters on the growth rate of Jeans instability.

    In this paper the effect of secondary electron emission on Jeans instability in a dusty plasma has been investigated. Due to secondary electron emission, dust grains may have two stable equilibrium states out of which one is negative and the other is positive. Here both cases have been considered separately. It has been shown that secondary electron emission enhances Jeans instability when equilibrium dust charge is negative. It has also been shown that growth rate of Jeans instability reduces with increasing secondary electron emission when equilibrium dust charge is positive.

    The thermal state of the intergalactic medium (IGM) at z Ly-alpha forest is degenerate with the 3-D structure of the IGM on ~100 kpc scales, where, analogous to the classical Jeans argument, the pressure of the T~$10^4$ K gas supports it against gravity. We simulate the IGM using smoothed particle hydrodynamics, and find that, at z Ly-alpha flux, $F_\\mathrm{real}$, which naturally suppresses dense gas, and is thus robust against the poorly understood physics of galaxy formation, revealing pressure smoothing in the diffuse IGM. The $F_\\mathrm{real}$ power spectrum is accurately described by a simple fitting function with cutoff at $\\lambda_F$, allowing us to rigorously quanti...

    2005-11-01

    This article analyzes the early evolution of Jean Piaget's renowned "clinical method" in order to investigate the method's strikingly original and generative character. Throughout his 1st decade in the field, Piaget frequently discussed and justified the many different approaches to data collection he used. Analysis of his methodological progression during this period reveals that Piaget's determination to access the genuine convictions of children eventually led him to combine 3 distinct traditions in which he had been trained-naturalistic observation, psychometrics, and the psychiatric clinical examination. It was in this amalgam, first evident in his 4th text, that Piaget discovered the clinical dynamic that would drive the classic experiments for which he is most well known. PMID:17152748

    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

  14. Jeans Instability of Rotating Viscoelastic Fluid in the Presence of Magnetic Field

    Sharma, Praveen Kumar; Argal, Shraddha; Tiwari, Anita; Prajapati, Ram Prasad

    2015-01-01

    The Jeans instability of rotating viscoelastic fluid in the presence of uniform magnetic field is investigated using the generalised hydrodynamic (GH) model. A general dispersion relation is derived with the help of linearised perturbation equations using the normal mode analysis, which is further discussed for axis of rotation parallel and perpendicular to the direction of the magnetic field in both the weakly coupled (hydrodynamic) and strongly coupled (kinetic) limits. The onset criterion of Jeans instability for magnetised rotating viscoelastic fluid is obtained, which remains unaffected by the presence of rotation and magnetic field but depends upon viscoelastic effects. The graphical illustrations are depicted to see the influence of rotation, Mach number, shear and viscous effects, and sound speed on the growth rate of Jeans instability. It is found that all these parameters have stabilising influence on the growth rate of Jeans instability; hence, they are capable of collapsing to a self-gravitating, rotating, magnetised viscoelastic medium.

    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.

    2010-01-01

    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. Marat was assassinated by Charlotte Corday in 1793, becoming a martyr for some segments of the society that worshiped his memory. He was a man with a complex and curious personality whose figure and legacy are still a matter of discussion. PMID:20361162

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

    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.

    From the time he became chef de service at La Salpêtrière Hospital in 1866 until his death in 1893, Jean-Martin Charcot oversaw 32 house officers. Some of them became famous, such as D.M. 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'.

  2. BOOK REVIEW: Jean-Charles Houzeau et son temps

    NASA Astrophysics Data System (ADS)

    Sterken, C.; Verhas, P.

    2002-12-01

    This is a wonderful book. It describes the life and work of Belgian astronomer Jean-Charles Houzeau (1820-1888) and, as the last three words of the title indicate, it has a broader focus including the social, industrial and scientific context of the second part of the 19th century. This is set in a very broad international social context including social revolutions in Belgium and France, and the abolition of slavery in the United States. The biography clearly shows that this hard-working man was driven by science and justice, by individualism and generosity, by humor and sentiment. The book is divided in four parts, each part is placed in its own historical context. The first part "The apprentice, the master and his disciples" describes Houzeau's childhood and young years, his early scientific career at the Observatory in Brussels, and his relationship with Adolphe Quetelet. The evolution of this relationship is very well documented: the turbulent revolutionary Houzeau versus cool, moderated and diplomatic royalist Quetelet, the observer versus the mathematician theorist. But both were very dedicated teachers: Quetelet established public courses and after the Revolution of 1830 he contributed to the foundation of the University of Brussels; Houzeau was the peripatetic teacher wherever place he was, also after his return to Belgium. The second part is "The politician" and deals with Houzeau's political ideas and revolutionary attitudes and their consequences. His revolutionary ideas, though, were not confined to politics only: he also severely criticised the paucity of high-precision observations collected at the Royal Observatory in his days. Because he participated at revolutionary meetings, Houzeau was fired from his position at the Observatory by the Minister of Interior Affairs Charles Rogier. Thus started his peripathetic life, covering observational work in astronomy, geography, geodesy and natural sciences in many places in Belgium and abroad. The third part, "The separation", is a very interesting account of Houzeau's emigration to North America, in vain search for his revolutionary dream. Of course he also ran into trouble in the US due to publications such as "The white terror in Texas" and because of his loyalty with the slaves, his advocacy for black civil rights and his refusal to join the confederate army, so he had to flee Texas too. The book gives many details on the civil war era. His absence from Belgium led to a very significant scientific work, in the first place his most homogeneous and extensive star atlas (6000 stars to declination -65) which was made in very good atmospheric conditions by one and only one observer, totally independent from previously published catalogues. The last part "The builder" tells the story of the construction of the new Royal Observatory in the suburb of Uccle, a new and better site than the one established in the city center by the Dutch regime in 1826. When the succession of Adolphe Quetelet was discussed, Houzeau was about the only candidate with a vast publication record and a broad observational expertise. Surprisingly, he was appointed as the second director of the Observatory and remained in function till 1883. One chapter in the fourth part of the book deals with Houzeau's participation at a Venus transit expedition of 1882. Jean-Charles Houzeau made very significant contributions to astronomy and his major works include "Vade-mecum de l'Astronomie", the "Uranometrie Generale" and his monumental "Bibliographie Generale de l'Astronomie", an early precursor of our modern web-based ADS (NASA Astrophysics Data System). This is a book which every Belgian astronomer should read because it is an eye opener on the history of the establishment of the kingdom, and because it explains the roots and difficult early development of astronomy in this country. This history is internationally linked and refers to many contemporary scientists such as Argelander, Heis, Herschel, von Humboldt etc. The bo

    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, and the resulting data were then processed using the Airborne Lidar Processing System (ALPS), a custom-built processing system developed in a NASA-USGS collaboration. ALPS supports the exploration and processing of Lidar data in an interactive or batch mode. Modules for presurvey flight line definition, flight path plotting, Lidar raster and waveform investigation, and digital camera image playback have been developed. Processing algorithms have been developed to extract the range to the first and last significant return within each waveform. ALPS is used routinely to create maps that represent submerged or first surface topography. Specialized filtering algorithms have been implemented to determine the 'bare earth' under vegetation from a point cloud of last return elevations.

  2. First seismic survey of Lake Saint-Jean (Québec, Canada): sedimentary record of the last deglaciation

    NASA Astrophysics Data System (ADS)

    Nutz, Alexis; Schuster, Mathieu; Ghienne, Jean-François; Raphaël, Certain; Nicolas, Robin; Claude, Roquin; Frédéric, Bouchette; Cousineau Pierre, A.

    2015-04-01

    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. The Lake Saint-Jean reveals important diversity and complexity. It is notably worth noting that the transition from glacial to post-glacial periods is well marked by an abrupt change in depositional dynamics. In addition, this work highlights an original lacustrine sedimentary system which is not straightforward notably because of the importance of erosion, by-pass and intermittent deposition over most of the lakefloor. As it deals with both glacial environments and lake systems, this works is of interest for all those concerned by the geological record of both the transition from glacial to post-glacial periods and the lacustrine environments.

    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 correlations are found for the case of pure thermal Jeans fragmentation, for which we infer a core formation efficiency in the range 12-34%, consistent with previous works. We conclude that the dominant factor determining the fragmentation level of star-forming massive dense cores seems to be thermal Jeans fragmentation.

    2014-09-01

    In the present work, the self-gravitational instability of quantum plasma is investigated including the effects of finite Larmor radius corrections (FLR) and rotation. The formulation is done employing quantum magnetohydrodynamic (QMHD) model. The plane wave solutions are employed on the linearized perturbed QMHD set of equations to obtain the general dispersion relation. The rotation is assumed only along the z- direction. The general dispersion relation is further reduced for transverse and longitudinal directions of propagation. It is found that in transverse direction of propagation the Jeans criterion is modified due to the rotation, FLR and quantum corrections while in longitudinal direction of propagation it is observed that the Jeans criterion is modified by quantum corrections only. The growth rate of perturbation is discussed numerically including the considered parameters FLR and quantum corrections. The growth rate is observed to be modified significantly due to the quantum correction and FLR effects.

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

    This paper is an attempt to reconstruct the historical, institutional, and personal circumstances leading to and surrounding Jean Piaget's psychoanalysis with Sabina Spielrein. 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 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.

    2015-10-01

    The paper considers Jean Barbeyrac's theory of permissive natural law, in particular its significance for his account of natural property rights. This interpretation contributes to current debates on permissive natural law in the early modern period by arguing that Barbeyrac's theory was more significant than hitherto acknowledged. The conceptual framework provided by Barbeyrac's theory of permissive natural law is crucial to understanding the ways in which his will-based theory of property departs not only from the consent-based theory of Samuel Pufendorf but also from the labor-based theory of John Locke with which he is most commonly associated.

    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.

    This article compares John Dewey's theory of inquiry with Jean Piaget's analysis of the mechanisms implied in the increase of knowledge. 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.

    In the framework of Newtonian cosmology or general relativity it is simple to derive a mass scale below which collapsed structures are relatively devoid of baryons. We examine how the inclusion of a chameleon scalar field affects this baryonic Jeans mass, bearing in mind both the canonical case of a gravitational-strength coupling between the scalar field and matter, as well as the strong coupling regime wherein the coupling is very large. We find that baryon effects persist down to smaller scales in a chameleon theory than they do in ordinary general relativity, especially in the case of strong coupling. Several potentially observable consequences of this are identified.

  7. Jeans analysis of the Galactic thick disk and the local dark matter density

    Sanchez-Salcedo, F J; de Diego, J A

    2015-01-01

    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 (F_z) and radial (F_R) components of the gravitational force, as well as Gamma(z), defined as the radial derivative of V_c^2, with V_c^{2}= -RF_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, Gamma 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 scale lengths of the density and velocity dispersions do not depend on the vertical height z a...

  8. The fluid mechanics of dark matter formation: Why does Jeans's (1902 & 1929) theory fail?

    E-print Network

    Carl H. Gibson

    1999-04-26

    Jeans's (1902 & 1929) linear gravitational instability criterion gives truly spectacular errors in its predictions of cosmological structure formation according to Gibson's (1996) new nonlinear theory. Scales are determined by viscous or turbulent forces, or by diffusivity, at Schwarz length scales L_SV, L_ST, or L_SD, respectively, whichever is larger. By these new criteria, void formation begins in the plasma epoch soon after matter dominates energy, at L approx L_SV = (gamma nu / rho G)^1/2 scales corresponding to protosuperclusters, decreasing to protogalaxies at the plasma-gas transition, where gamma is the rate-of-strain of the expanding universe, nu is the kinematic viscosity, rho is the density, and G is Newton's gravitational constant. Condensation of the primordial gas occurs at mass scales a trillion times less than the Jeans mass to form a `fog' of micro-brown-dwarf (MBD) particles that persist as the galactic baryonic dark matter, as reported by Schild (1996) from quasar-microlensing studies. Nonbaryonic dark matter condensation is prevented by its enormous diffusivity at scales smaller than L_SD = (D^2 /rho G)^1/2, where D is the diffusivity, so it forms outer halos of galaxies, cluster-halos of galaxy clusters, and supercluster-halos.

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

    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 Ly? 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 Ly? 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 Ly? forest is used to generate a large grid (500) of thermal models from a dark matter only simulation. Our full parameter study indicates that a realistic sample of only 20 close quasar pair spectra can pinpoint the Jeans scale to ? 5% precision, independent of the amplitude T{sub 0} and slope ? of the temperature-density relation of the IGM T=T{sub 0}(?/ ?-bar ){sup ?-1}. This exquisite sensitivity arises because even long-wavelength one-dimensional Fourier modes ?10 Mpc, i.e., two orders of magnitude larger than the Jeans scale, are nevertheless dominated by projected small-scale three-dimensional (3D) power. Hence phase angle differences between all modes of quasar pair spectra actually probe the shape of the 3D power spectrum on scales comparable to the pair separation. We show that this new method for measuring the Jeans scale is unbiased and is insensitive to a battery of systematics that typically plague Ly? forest measurements, such as continuum fitting errors, imprecise knowledge of the noise level and/or spectral resolution, and metal-line absorption.

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

    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 that simultaneously addresses numerous thorny issues regarding the SFRs of high-z galaxies.

    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.

    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.

    Specialists of the history of hysteria know the name of Jean-Louis Brachet (1789-1858), but few realise the influence of this physician and surgeon from Lyon, a city in the southeastern part of France. Not only a clinician, he was also a neurophysiology researcher in the early 19th century. Along with his descriptions of meningoencephalitis, including hydrocephalus and meningoencephalitis, he elucidated the functioning of the vegetative nervous system and described its activity during emotional states. He also helped describe the different forms of epilepsy and sought to understand their aetiologies, working at the same time as the better-known Louis-Florentin Calmeil (1798-1895). We present a biography of this forgotten physician, a prolific writer, keen clinical observer and staunch devotee of a rigorous scientific approach. PMID:26318891

    The hypothesis of antigravitational interaction of elementary particles and antiparticles is applied to the simple two-component hydrodynamic model ?-CDM (Lambda cold-dark matter) with gravitational repulsion and attraction. An increase in the Jeans instability rate, the presence of antiscreening, and the dominant role of the gravitational repulsion as a possible mechanism of spatial separation of matter and antimatter in the Universe are shown, as well as the observable acceleration of far galaxies. The sound wave is found for the two-component gravitational-antigravitational system. The suggested approach permits to reestablish the idea about baryon symmetry of the Universe, causing its steady large-scale flatness and accelerated Universe expansion.

    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.

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.

    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

    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

    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.

    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.

  16. Modified Jeans instability of magnetized viscous spin 1/2 quantum plasma with resistive effects and Hall current

    The effect of Hall current on Jeans self-gravitational instability is examined for finitely conducting dense quantum viscous plasma in the presence of spin generated magnetization. The basic equations of the problem are constructed using quantum magneto hydrodynamic (QMHD) model. The Hall and resistivity terms are incorporated in the idealized Ohm's law and spin induced magnetization and viscosity terms are incorporated to the momentum equations. The general dispersion relation is found to be modified due to the presence of Hall current, electrical resistivity and viscosity parameter along with the spin induced magnetization. The dispersion relation is further reduced for both transverse and longitudinal mode of propagations. In the transverse mode of propagation the Jeans condition of instability is modified due to Alfven velocity, magnetization parameter and quantum corrections, and the growth rate of instability is found to be modified due to the electrical resistivity, viscosity, magnetization parameter and quantum corrections but remains unaffected by the presence of Hall current. In longitudinal direction of propagation the gravitational mode is affected due to the viscosity and quantum parameter while the Jeans condition of instability depends only upon the quantum correction. The Alfven mode in longitudinal direction gets modified due to the electrical resistivity, Hall current, viscosity and magnetization parameter however, it is found to be independent of quantum corrections. The numerical observations are also presented to show the effect of electrical resistivity, magnetization and quantum corrections on the growth rate of instability.

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

  18. Comparison of the velocity distribution between the adhesion approximation and the Euler-Jeans-Newton model

    For the evolution of density fluctuation in nonlinear cosmological dynamics, adhesion approximation (AA) is proposed as a phenomenological model, which is especially useful for describing nonlinear evolution. However, the origin of the artificial viscosity in AA is not clarified. Recently, Buchert and Domínguez report if the velocity dispersion of the dust fluid is regarded as isotropic, it works on a principle similar to viscosity or effective pressure, and they consider isotropic velocity dispersion as the origin of the artificial viscosity in AA. They name their model the Euler-Jeans-Newton (EJN) model. In this paper, we focus on the velocity distribution in AA and the EJN model and examine the time evolution in both models. We find the behavior of AA differs from that of the EJN model, i.e., although the peculiar velocity in the EJN model oscillates, that in AA is monotonically decelerated due to viscosity without oscillation. Therefore it is hard to regard viscosity in AA as effective pressure in the EJN model.

    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

    We study the effect of contamination by interlopers in kinematic samples of galaxy clusters. We demonstrate that without the proper removal of interlopers the inferred parameters of the mass distribution in the cluster are strongly biased towards higher mass and lower concentration. The interlopers are removed using two procedures previously shown to work most efficiently on simulated data. One is based on using the virial mass estimator and calculating the maximum velocity available to cluster members and the other relies on the ratio of the virial and projected mass estimators. We illustrate the performance of the methods in detail using the example of A576, a cluster with a strong uniform background contamination, and compare the case of A576 to 15 other clusters with different degree of contamination. We model the velocity dispersion and kurtosis profiles obtained for the cleaned data samples of these clusters solving the Jeans equations to estimate the mass, concentration and anisotropy parameter. We present the mass-concentration relation for the total sample of 22 clusters.

    J. Magnol came from Ardèche to Montpellier to learn how to be apothecary grocer. He is characteristics of the transition between the Middle-Ages statutes and Renaissance ones (1572/1598) in a city famous for its school of medicine. For thirteen (13) years he worked as a journeyman apothecary was like a drysalter grocer. But the 1572 statutes due to king Henry IV (the fourth), having force of law, changed the trade into an art, as highly regarded as the legal profession. 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 Magnol is Pierre Magnol's ancestor (1638-1715), the famous botanist whom Carl Linné dedicated the magnolia genus to. PMID:17526144

  4. Jean-Martin Charcot's role in the 19th century study of music aphasia.

    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.

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

    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].

  6. Chapter 15: Jean-Martin Charcot and the anatomo-clinical method of neurology.

    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.

    Interviewed by Development Forum, the director of UNCED's New York office, Jean-Claude Faby, who has been intimately involved in the negotiations preceding the Earth Summit, discusses his view of the process and expectations of global meeting. Faby explains that during the preparatory process, nongovernmental organizations (NGOs) have played an instrumental role. For example, women have raised issues concerning women, and their efforts are reflected in Agenda 21, the action plan of the Rio Declaration. Although describing the NGOs' critical assessment of the process as a health impatience, Faby notes that the issues to be confronted in Rio are some of the most complicated and vexing environmental and development problems facing the world community. Faby explains that the business community, an important player in the issues at hand, has also taken an active role in the negotiations. Faby acknowledges that the negotiations have witnessed a rift between North and South over the language of the document, a debate that will probably continue during the summit itself. Some of the issues of contention are military spending (a particularly concern of NGOs) and the North's high level of consumption, which the South insists must be addressed. Faby also discusses the issue of implementation and funding following the conclusion of the summit. Although implementation would require some $125 billion (a relatively modest figure), Faby expects that no neat funding package will emerge from Rio. In fact, funding will be one of the primary concerns of the Rio follow-up. Concerning the institutional follow-up of the summit, some are calling for the formation of a new institution, while others oppose such a move. PMID:12343708

    Deltas simultaneously respond to modifications in water discharge, sediment supply and base-level change. 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 of deglacial successions in previously glaciated areas for both Quaternary and pre-Quaternary periods. This contribution is of interest for a wide range of geoscientists such as a large number of Quaternary geologists or pre-Quaternary geologists interested by ancient deglaciations.

    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 Bia?owie?a 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 trade (wolverine, bobak marmot or steppe polecat). Also in these cases, Gilibert's descriptions were often the first reliable information that entered the circulation in European science. His accounts were not free of errors and mistakes--but they resulted mainly from the pioneering role of his work. Some of his breeding experiments can arouse the reader's sincere smile today, such as an attempt to feed a beaver with fish or serve cooked beans to a lynx In the margins of his mammal observations, Gilibert described also the place of their occurrence, extensive forests of the Grand Duchy of Lithuania. Read from the contemporary perspective, his thoughts are surprisingly relevant. In his praise of "primeval nature, free from human actions and not disturbed by accident or by the impatience of human desires" he sounds very similar to today's eulogists of the primeval forest of Bia?owie?a.

  14. 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.

  15. Exploring Extinction and Structure in the Milky Way Disk with the Rayleigh-Jeans Color Excess Method

    Because the Milky Way is the primary laboratory for detailed exploration of the evolution of galaxies, understanding the complex structure and composition of its disk is a critical step toward defining its morphology and placing it properly within the extragalactic context. However, much of the disk structure and stellar population information lies hidden among and behind thick and clumpy dust clouds. We have found that a potent means for disentangling the stellar and interstellar dust distributions lies in the combination of near- and mid-infrared photometry, which, by sampling the Rayleigh-Jeans part of the stellar spectral energy distribution, has the ability to separate rather cleanly the intrinsic stellar characteristics from dust reddening effects. Here we describe the "Rayleigh-Jeans Color Excess" (RJCE) method, which has the advantage over other photometric dereddening techniques of preserving stellar type and luminosity class information for each star throughout the dereddening process. We apply the RJCE method to present not only new maps of the distribution of dust across the Galactic disk, but also "clean," reddening-corrected color magnitude diagrams (CMDs) of highly extinguished fields whose raw CMDs are not readily interpretable in a stellar populations context. Our RJCE extinction maps of the highly reddened Galactic midplane trace both the diffuse and filamentary extinction predicted by molecular emission much more accurately than the commonly used extinction maps derived from long-wavelength dust emission. We demonstrate how the retention of stellar type and luminosity information, discernible from our dereddened CMDs, facilitates three-dimensional, model-independent stellar and extinction mapping. This powerful technique and its data products will improve Galactic extinction corrections, facilitate target selection for prominent upcoming Galactic surveys, and enable exploration of elusive Galactic midplane structural and halo substructural features.

    Dwarf spheroidal (dSph) galaxies are among the most promising targets for the indirect detection of dark matter (DM) from annihilation and/or decay products. Empirical estimates of their DM content - and hence the magnitudes of expected signals - rely on inferences from stellar-kinematic data. However, various kinematic analyses can give different results and it is not obvious which are most reliable. Using extensive sets of mock data of various sizes (mimicking `ultrafaint' and `classical' dSphs) and a Markov Chain Monte Carlo engine, here we investigate biases, uncertainties and limitations of analyses based on parametric solutions to the spherical Jeans equation. For a variety of functional forms for the tracer and DM density profiles, as well as the orbital anisotropy profile, we examine reliability of estimates for the astrophysical J- and D-factors for annihilation and decay, respectively. For large (N ? 1000) stellar-kinematic samples, typical of `classical' dSphs, errors tend to be dominated by systematics, which can be reduced through the use of sufficiently general and flexible functional forms. For small (N ? 100) samples typical of `ultrafaints', statistical uncertainties tend to dominate systematic errors and flexible models are less necessary. We define an optimal strategy that would mitigate sensitivity to priors and other aspects of analyses based on the spherical Jeans equation. We also find that the assumption of spherical symmetry can bias estimates of J (with the 95 per cent credibility intervals not encompassing the true J-factor) when the object is mildly triaxial (axis ratios b/a = 0.8, c/a = 0.6). A concluding table summarizes the typical error budget and biases for the different sample sizes considered.

    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 = ?/(?{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: ?{sub J} = (5?/G){sup 1/2}Q{sup ?1/3}?{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 ?}.

  20. Model for common growth of supermassive black holes, bulges and globular star clusters: ripping off Jeans clusters

    It is assumed that a galaxy starts as a dark halo of a few million Jeans clusters (JCs), each of which consists of nearly a trillion micro brown dwarfs, MACHOs of Earth mass. JCs in the galaxy center heat up their MACHOs by tidal forces, which makes them expand, so that coagulation and star formation occurs. Being continuously fed by matter from bypassing JCs, the central star(s) may transform into a super massive black hole. It has a fast $t^3$ growth during the first mega years, and a slow $t^{1/3}$ growth at giga years. JCs disrupted by a close encounter with this black hole can provide matter for the bulge. Those that survive can be so agitated that they form stars inside them and become globular star clusters. Thus black holes mostly arise together with galactic bulges in their own environment and are about as old as the oldest globular clusters. The age 13.2 Gyr of the star HE 1523-0901 puts forward that the Galactic halo was sufficiently assembled at that moment. The star formation rate has a maximum at black hole mass $\\sim4 \\ 10^7M_\\odot$ and bulge mass $\\sim5\\,10^{10}M_\\odot$. In case of merging supermassive black holes the JCs passing near the galactic center provide ideal assistance to overcome the last parsec.

    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.

    Corda, Mosquera Cuesta and Lorduy G\\`omez have shown that spherically symmetric stationary states can be used as a model for galaxies in the framework of the linearized \\textbf{\\ensuremath{R^{2}}} gravity. Those states could represent a partial solution to the Dark Matter Problem. Here we discuss two improvements of such a work. First, we show that the results hold also in the full \\textbf{\\ensuremath{R^{2}}} gravity theory because the wave solution found in previous work is also solution of the full field equations. Second, as the star density is a functional of the invariants of the associated Vlasov equation, we show that any of these invariants is in its turn a functional of the local energy and the angular momentum. As a consequence, the star density depends only on these two integrals of the Vlasov system. This result is known as the "Jeans theorem". In addition, we find an analogous of the historical Tolman-Oppenheimer-Volkov equation for the system considered in this paper. For the sake of completeness, in the final Section of the paper we consider two additional models which argue that Dark Matter could not be an essential element.

A certain example of the yet cooler Y-type spectral class (Teff brown dwarfs indicate that substellar companions with large semi-major axes and with masses less than the brown dwarf/giant planet dividing line (~13.5 Mj) are rare. Theoretical considerations of Jeans mass fragmentation of molecular clouds are consistent with this minimum mass cutoff and also with the semi-major axis (hundreds of AU) characteristic of the lowest mass imaged companions. As a consequence, Y-class companions with large semi-major axes should be scarce around stars brown dwarf companions to young stellar primaries, it is possible to derive a first estimate of the brown dwarf IMF over the entire range of brown dwarf masses (13 Mj to 79 Mj) -- the number of companion brown dwarfs is proportional to mass to the -1.2+-0.2 power.

    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

    Leigh syndrome (LS) affects 1/40,000 newborn infants in the worldwide population and is characterized by the presence of developmental delay and lactic acidosis and by a mean life expectancy variously estimated at 3-5 years. Saguenay-Lac-Saint-Jean (SLSJ) cytochrome oxidase (COX) deficiency (LS French-Canadian type [LSFC] [MIM 220111]), an autosomal recessive form of congenital lactic acidosis, presents with developmental delay and hypotonia. It is an LS variant that is found in a geographically isolated region of Quebec and that occurs in 1/2,178 live births. Patients with LSFC show a phenotype similar to that of patients with LS, but the two groups differ in clinical presentation. We studied DNA samples from 14 patients with LSFC and from their parents, representing a total of 13 families. Because of founder effects in the SLSJ region, considerable linkage disequilibrium (LD) was expected to surround the LSFC mutation. We therefore performed a genomewide screen for LD, using 290 autosomal microsatellite markers. A single marker, D2S1356, located on 2p16, showed significant (P < 10(-5)) genomewide LD. Using high-resolution genetic mapping with additional markers and four additional families with LSFC, we were able to identify a common ancestral haplotype and to limit the critical region to approximately 2 cM between D2S119 and D2S2174. COX7AR, a gene encoding a COX7a-related protein, had previously been mapped to this region. We determined the genomic structure and resequenced this gene in patients with LSFC and in controls but found no functional mutations. Although the LSFC gene remains to be elucidated, the present study demonstrates the feasibility of using a genomewide LD strategy to localize the critical region for a rare genetic disease in a founder population.

  8. Crime, hysteria and belle époque hypnotism: the path traced by Jean-Martin Charcot and Georges Gilles de la Tourette.

    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

    Cosmic structure formation is characterized by the complex interplay between gravity, turbulence, and magnetic fields. The processes by which gravitational energy is converted into turbulent and magnetic energies, however, remain poorly understood. Here, we show with high-resolution, adaptive-mesh simulations that MHD turbulence is efficiently driven by extracting energy from the gravitational potential during the collapse of a dense gas cloud. Compressible motions generated during the contraction are converted into solenoidal, turbulent motions, leading to a natural energy ratio of E{sub sol}/E{sub tot} {approx} 2/3. We find that the energy injection scale of gravity-driven turbulence is close to the local Jeans scale. If small seeds of the magnetic field are present, they are amplified exponentially fast via the small-scale dynamo process. The magnetic field grows most efficiently on the smallest scales, for which the stretching, twisting, and folding of field lines, and the turbulent vortices are sufficiently resolved. We find that this scale corresponds to about 30 grid cells in the simulations. We thus suggest a new minimum resolution criterion of 30 cells per Jeans length in (magneto)hydrodynamical simulations of self-gravitating gas, in order to resolve turbulence on the Jeans scale, and to capture minimum dynamo amplification of the magnetic field. Due to numerical diffusion, however, any existing simulation today can at best provide lower limits on the physical growth rates. We conclude that a small, initial magnetic field can grow to dynamically important strength on timescales significantly shorter than the free-fall time of the cloud.

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

    The relationships between fluid circulation and deformation are one of the issues of the sedimentary basin study. In the Cretaceous flysch of the Saint-Jean-de-Luz basin, the evolution of folds geometry and the increasing volume of calcite-filled fractures and veins evidence a northward deformational gradient along the French Basque coast. A combined approach is proposed to assess the corresponding physical and chemical conditions: the microthermometric study of fluid inclusions in calcite sampled in different generations of veins and fractures and the X-ray diffraction analysis of clay minerals from adjacent marl layers. Salinity of the trapped H2O-CaCl2-NaCl fluids increases with depth in the series, in good agreement with salinity gradients reported in sedimentary basins. Dispersion of the data also increases with depth from 0.3 to 1.3 wt.% NaCl eq. in the shallowest formation (Haizabia flysch) to 9.1 to 23.0 wt.% NaCl eq. in the deepest formation (Guéthary flysch). Minimal trapping temperatures of the fluids in the Haizabia and Socoa flyschs (79 and 102 °C, respectively) are consistent with the temperatures estimated from the depth of burial, which did not exceed 5 km, in good agreement with the stability of the smectite-illite-kaolinite assemblage found in marls. In addition, the kaolinite proportion significantly decreases with depth in the series, as a potential consequence of climate changes and diagenetic transformations, whereas the increasing dispersion of illite crystallinity data might indicate fluid-mineral interactions. We propose a synthetic model of fluid circulation in the folded series that involves the mixing of mainly-horizontal fluid circulation (potentially meteoric) with an upward flow of high-salinity fluid throughout the deepest formations (potentially related to underlying evaporite-rich layers). The northward deformational gradient, as exposed along the French Basque coast, is likely to be responsible for such a vertical circulation, by increasing the volume of fracture (particularly cross-cutting fractures) in the deeply buried formations.

Thus, changes in stellar NIR-MIR colors due to interstellar reddening are readily apparent, and (under an assumed extinction law) the observed colors and magnitudes of stars can be easily and accurately restored to their intrinsic values, greatly increasing their usefulness for Galactic structure studies.

    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

    The problem of structure formation in relativistic dissipative fluids was analyzed in a previous work within Eckart's framework, in which the heat flux is coupled to the hydrodynamic acceleration, additional to the usual temperature gradient term. It was shown that in such case, the pathological behavior of fluctuations leads to the disapperance of the gravitational instability responsible for structure formation. In the present work the problem is revisited now using a constitutive equation derived from relativistic kinetic theory. The new relation, in which the heat flux is not coupled to the hydrodynamic acceleration, leads to a consistent first order in the gradients formalism. In this case the gravitational instability remains, and only relativistic corrections to the Jeans wave number are obtained. In the calculation here shown the non-relativistc limit is recovered, opposite to what happens in Eckart's case.

    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

    The Milky Way (MW) remains a primary laboratory for understanding the structure and evolution of spiral galaxies, but typically we are denied clear views of MW stellar populations at low Galactic latitudes because of extinction by interstellar dust. However, the combination of Two Micron All-Sky Survey (2MASS) near-infrared (NIR) and Spitzer-IRAC mid-infrared (MIR) photometry enables a powerful method for determining the line-of-sight reddening to any star: the sampled wavelengths lie in the Rayleigh-Jeans part of the spectral energy distribution of most stars, where, to first order, all stars have essentially the same intrinsic color. Thus, changes in stellar NIR-MIR colors due to interstellar reddening are readily apparent, and (under an assumed extinction law) the observed colors and magnitudes of stars can be easily and accurately restored to their intrinsic values, greatly increasing their usefulness for Galactic structure studies. In this paper, we explore this "Rayleigh-Jeans Color Excess" (RJCE) method and demonstrate that use of even a simple variant of the RJCE method based on a single reference color, (H -[4.5?]), can rather accurately remove dust effects from previously uninterpretable 2MASS color-magnitude diagrams of stars in fields along the heavily reddened Galactic midplane, with results far superior to those derived from application of other dereddening methods. We also show that "total" Galactic midplane extinction looks rather different from that predicted using 100? emission maps from the IRAS/ISSA and COBE/DIRBE instruments as presented by Schlegel et al. Instead, the Galactic midplane extinction strongly resembles the distribution of 13CO (J = 1?0) emission. Future papers will focus on refining the RJCE method and applying the technique to understand better not only dust and its distribution but also the distribution of stars intermixed with the dust in the low-latitude Galaxy.

  20. 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 good potential sites to monitor wood delivery from the catchment through time and allow estimations of LW residence time while in transit. These results contribute to understanding the interannual large wood dynamics in the Saint-Jean River and can assist river managers in determining sustainable solutions for coping with the issue of wood rafts in rivers.

  1. Who was first to diagnose and report neuropathic arthropathy of the foot and ankle: Jean-Martin Charcot or Herbert William Page?

    PubMed

    Sanders, Lee J; Edmonds, Michael E; Jeffcoate, William J

    2013-09-01

    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

    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, while Vulpian was progressively relegated to the studies of historians. However, Vulpian and Charcot remain inseparable in the memory of a lifelong friendship which gave birth to neurology. PMID:21422760

    Fish and aquatic invertebrate communities in waterways of the Barataria Preserve of Jean Lafitte National Historical Park and Preserve, Louisiana, were surveyed from 1999 to 2000. An inventory of fish in the Barataria Preserve was established, and concentrations of selected organochlorine pesticides, polychlorinated biphenyls, and trace elements; iron; and manganese in fish tissue for selected species were determined. The fish and aquatic invertebrate sampling completed for this study indicated that abundant and diverse communities are present in the Barataria Preserve. Thirty-two species of fish were identified in the Barataria Preserve during this survey. The total number of species identified in a single sampling ranged from 20 to 26. Most of the fish sampled are designated as intermediate in their tolerance to poor water quality. Three species of fish designated as tolerant (common carp, Cyprinus carpio; golden shiner, Notemigonus crysoleucas; and yellow bullhead, Ameiurus natalis), and one as intolerant (lake chubsucker, Erymizon sucetta), were identified. In November 1999, the average total weight of all fish collected by boat-mounted electroshocker from a single site was about 35,000 grams; in May and July 1999, the average total weight was between 9,000 and 10,000 grams. The contribution of spotted gar (Lepisosteus oculatus) to the total weight of the fish averaged between 38 and 41 percent among the three sample periods. Members of the sunfish family (Centrarchidae) contributed between 18 and 28 percent of the total weight. For each sampling period, 60 to 83 percent of the total weight from the sunfish family was contributed by bluegill (Lepomis macrochirus) and largemouth bass (Micropterus salmoides). Aquatic invertebrates were sampled at three sites. Most aquatic invertebrates identified were freshwater species, but some were brackish-water and marine species. About 234,000 organisms were identified and enumerated from the richest-targeted habitat (RTH, floating rafts of aquatic plants). Individuals from 84 genera belonging to 51 families were identified. Diptera (true flies) was the most diverse group. Malacostraca (crustaceans), especially Amphipoda (scuds and sideswimmers), were the most abundant (36 percent). Total abundance and taxa richness of aquatic invertebrates were comparable during the March and July sampling in 1999, but were lower in samples collected from the same habitat at all three sites in April 2000. About 106 individuals were identified and enumerated from the depositional-targeted habitat (DTH, bottom material). Individuals from 7 genera belonging to 9 families were identified. Diptera was the most diverse group, and Annelida, especially tubificid worms, were the most abundant organisms identified (52 percent). Total abundance and composition of aquatic invertebrate communities differed between RTH and DTH at all three sites in April 2000. Organic compounds in whole fish, and trace elements, iron, and manganese in fillets, were analyzed in bowfin (Amia calva), bluegill (Lepomis macrochirus), largemouth bass (Micropterus salmoides), and common carp (Cyprinus carpio). Organic compounds were not detected. Mercury was detected in fillets of all four species. Highest concentrations of mercury were detected in fillets from bowfin and largemouth bass. Mercury concentrations increased with increasing weight in the three predatory fish species (bowfin, bluegill, and largemouth bass), but were much lower, relative to weight, in the omnivore, common carp. Chromium concentrations were detected in tissue of the two larger fish, bowfin and common carp. Cadmium and lead were not detected in any samples. Mercury concentrations for larger predatory fish caught in Preserve waterways may be a concern if the fish are frequently consumed by humans. The process of mercury accumulation appears to be natural, and not related to a local source problem. Mercury concentrations in comparable fish tissue at

    We provide new, high-resolution A(Ks ) extinction maps of the heavily reddened Galactic midplane based on the Rayleigh-Jeans Color Excess ("RJCE") method. RJCE determines star-by-star reddening based on a combination of near- and mid-infrared photometry. The new RJCE-generated maps have 2' × 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° < l < 65° and, in general, for |b| <= 1°-1fdg5 (extending up to |b| <= 4° 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 ~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(Ks ). 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.

She said, "You are going to like this couple, kind of simple but really nice. Ask him about his surgery." Okay, I think to myself, I cannot wait to hear this tale. I was expecting to hear about the hours and hours of surgery and the details of the intricate procedure performed to remove his extensive head and neck cancer. I walked into our education room and was greeted by a very slight older man with a big toothless smile and, alongside him, his graying wife, both with the same welcoming warmth.

  7. Improving the Geologic Time Scale (Jean Baptiste Lamarck Medal Lecture)

    NASA Astrophysics Data System (ADS)

    Gradstein, Felix M.

    2010-05-01

    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.

    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.

    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.

  12. 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.

    Roberts, Brian Arthur

    2015-02-01

    In Arthur Frank's book The Wounded Storyteller, the illness story is brought to life, highlighting the disruption in the life course that serious illness brings. Frank shows that a narrative can aid suffers by giving a voice to those silenced within the health system. In this article, one sufferer marginalized within the health care system is offered a voice, and writing the illness story is explored as a healing process for the author, whose mother suffered from Alzheimer's disease some 30 years ago. Elements of Frank's theoretical processes ofa "chaos story" and a "quest story" are combined in the author's attempt to gain closure with the health and political systems. The author highlights the absence of a meaningful social work intervention, makes recommendations from an anti-oppressive perspective, and offers a discussion of social work interventions that have developed over time. Further, the author advocates for adaptation in a system ill prepared for the possible future onslaught of dementia cases and details how the illness-story narrative can be used as a therapeutic tool for caregivers.
