Jeans instability in a universe with dissipation

NASA Astrophysics Data System (ADS)

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

2018-01-01

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

2001-05-01

The prevalence of fear was explored in 340 adolescents in Al-Ain, United Arab Emirates. More than 50% reported feeling extremely frightened of 6 out of 60 fear items surveyed. These items were: someone dying in the family (66.5%), parents getting divorced (65.3%), the devil (63.8%), breaking a religious law (61.5%), being kidnapped (53.2%) and being adopted (49.9%). The level of fear showed a significant positive correlation with female gender, parental death/divorce, living with a single parent/relatives, living in low income families and an adverse home environment. Nearly half of the children reported that the fear caused considerable distress and interfered with daily activities.

2014-09-15

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

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

Demonic possession by Jean Lhermitte.

Drouin, E; Péréon, T; Péréon, Y

2017-08-01

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

THERMALLY DRIVEN ATMOSPHERIC ESCAPE: TRANSITION FROM HYDRODYNAMIC TO JEANS ESCAPE

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

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

2011-03-10

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

Philipp Bozzini (1773-1809): The earliest description of endoscopy.

Ramai, Daryl; Zakhia, Karl; Etienne, Denzil; Reddy, Madhavi

2018-05-01

The widespread use of endoscopy in today's clinical arena underscores its utility and growing significance within the field of medicine. Primitive forms of endoscopy have existed for hundreds of years, but it was not until the early 19th century that Dr Philipp Bozzini invented an endoscope that would form the basis of modern endoscopy. Born into an influential Italian family, Bozzini practiced medicine in a time and place of conflict and political unrest. His passion, ingenuity, and important social connections allowed him to create and introduce to the medical profession the Lichtleiter (light-conductor), which overcame two key issues plaguing endoscopy: inadequate lighting and poor penetration. A combination of professional rivalry and his premature passing stifled enthusiasm and further work on the Lichtleiter, but its value would not be lost forever. The advancements in the field of endoscopy that have come since the time of the Lichtleiter all build upon the principles of Bozzini, who became widely acknowledged as the father of modern endoscopy.

2018-05-01

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

Jeans instability with exchange effects in quantum dusty magnetoplasmas

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

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

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

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

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

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

NASA Technical Reports Server (NTRS)

Wollkind, David J.; Yates, Kemble R.

1990-01-01

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

2007-01-01

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

The Commissioner was accompanied, among others, by the EU Ambassador to Chile, Mr. Wolfgang Plasa, and Ms. Christina Lazo, Executive Director of the Chilean Science and Technology Agency (CONICYT). The distinguished visitors were able to acquaint themselves with one of the foremost European research facilities, the ESO Very Large Telescope (VLT), during an overnight stay at this remote site. Arriving after the long flight from Europe in Antofagasta, capital of the II Chilean region, the Commissioner continued along the desert road to Paranal, some 130 km south of Antofasta and site of the world's largest and most efficient optical/infrared astronomical telescope facility. The high guests were welcomed by the ESO Director General, Dr. Catherine Cesarsky, and the ESO Representative in Chile, Mr. Daniel Hofstadt, as well as ESO staff members of many nationalities. The visitors were shown the various high-tech installations at the observatory, including many of the large, front-line VLT astronomical instruments that have been built in collaboration between ESO and European research institutes. Explanations were given by ESO astronomers and engineers and the Commissioner gained a good impression of the wide range of exciting research programmes that are carried out with the VLT. Having enjoyed the spectacular sunset over the Pacific Ocean from the KUEYEN telescope, one of the four 8.2-m telescopes that form the VLT array, the Commissioner visited the VLT Control Room from where the four 8.2-m Unit Telescopes and the VLT Interferometer (VLTI) are operated. Here, the Commissioner was invited to follow an observing sequence at the console of the KUEYEN telescope. " This is a tribute to the human genius ", commented the Commissioner.

Heinrich Hertz and Philipp Lenard: Two Distinguished Physicists, Two Disparate Men

Mulligan, Joseph F.

1999-12-01

Heinrich Hertz (1857-1894) and Philipp Lenard (1862-1947) both had distinguished careers as physicists. They were together in Bonn from April 1891 to January 1894, Hertz as Director of the Bonn Physics Institute, and Lenard as his assistant. Each did important experimental work on cathode rays and the photoelectric effect, and in 1905 Lenard received the Nobel Prize for his work in these fields. Lenard had great respect and admiration for Hertz before going to Bonn and while there, but gradually allowed his esteem for his mentor (who died in 1894) to diminish as Lenard became increasingly anti-Semitic and involved in National Socialism and the Nazi movement. This article illustrates how differences in their characters and personalities, together with the tragic events of the Great War and its aftermath, resulted in Hertz deservedly being much more highly regarded today both as a physicist and as a man than is Lenard.

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

2011-01-15

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

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

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

Reappraising Positivism and Education: The Arguments of Philipp Frank and Herbert Feigl

NASA Astrophysics Data System (ADS)

Matthews, Michaelr.

This paper documents some of the `bad press' that Positivism has received in science education; it delineates the varied, and sometimes contradictory, ways in which educationalists characterize positivism; it indicates that Constructivism shares the same philosophical commitments as the instrumentalist tradition in positivism; and it suggests that there is considerable educational gain in reconsidering the philosophical and educational commitments of the non-instrumentalist, logical empiricist, tradition in positivism. The paper proceeds by examining and elaborating upon two educational papers of Vienna Circle members Philipp Frank and Herbert Feigl. It is argued that a number of the philosophical and educational `principles' of these foundational positivists are of value to educators facing a worldwide drift from natural sciences in schools and universities, and an increasingly strident anti-science lobby in universities and society. There are at least some positivist babies that should not be thrown out with the educational bathwater.

Macchia, Giovanni

2014-05-01

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

Physical interpretation of Jeans instability in quantum plasmas

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

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

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 wouldmore » proceed forever. This limiting mass is found to depend strongly on the composition of the quantum plasma and the atomic-number of the constituent ions, where it is observed that heavier elements rather destabilize the quantum plasma hydrodynamically. It is also shown that the Chandrasekhar mass-limit for white dwarf stars can be directly obtained from the hydrostatic limit of our model.« less

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

NASA Astrophysics Data System (ADS)

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

2013-10-01

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

In "The (unfortunate) complexity of the economy" (April pp28-32) Jean-Philippe Bouchaud presents clear evidence that traditional assumptions of rational markets have to be abandoned. The old investor slogan "buy on promise, sell on rumour" quickly magnifies a downturn into a crisis, which triggers two questions. If physics-based models are applied (beyond understanding and prediction) to actual market decisions, does this make the economy more or less stable? And, is this cause for stronger regulation?

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

NASA Astrophysics Data System (ADS)

A, ABBASI; M, R. RASHIDIAN VAZIRI

2018-03-01

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

Stomach and psyche: eating, digestion, and mental illness in the medicine of Philippe Pinel.

PubMed

Williams, Elizabeth A

2010-01-01

In premodern medicine eating and digestion were often linked to psychic disturbance, yet modern "mental medicine" is generally thought to have abandoned this ancient assumption. The work of Philippe Pinel, founder of French psychiatry and advocate of the "moral treatment," has been regarded as indicative of this process, but in fact eating and digestion remained important to Pinel's understanding of the néuroses, the variety of disease within which he classified both mild and severe forms of mental illness. Pinel's theoretical and clinical innovations in regard to maladies that blended mental and gastric distress left an important legacy both to asylum-based psychiatry and to medical generalists working in private settings in the nineteenth century. Today his work remains valuable for its insistence on the inextricability of the "physical and the moral" in psycho-gastric illness.

Effect of rotation on Jeans instability of magnetized radiative quantum plasma

NASA Astrophysics Data System (ADS)

Joshi, H.; Pensia, R. K.

2017-03-01

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

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

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

Sharma, Prerana; Chhajlani, R. K.

2013-09-15

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

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

The birth of the most important 18th century dental text: Pierre Fauchard's Le Chirurgien Dentiste.

PubMed

Spielman, Andrew I

2007-10-01

Pierre Fauchard (1678-1761) is considered the father of modern dentistry. His seminal book, Le Chirurgien Dentiste, ou Traité des Dents (1728), is the discipline's first complete work. During the five years preceding its publication (1723-1728), Pierre Fauchard sought the opinions, contributions, and "approbation" (approval) of 19 of his colleagues: six physicians, 12 surgeons, and one dentist. The first and most important contributor to the manuscript was Jean Devaux, surgeon and mentor to Fauchard. The next six reviewers were illustrious physicians and scientists of the time: Philippe Hecquet, Jean-Claude Adrien Helvetius, Jean Baptiste Silva, Antoine DeJussieu, Raymond Jacob Finot, and Antoine Benignus Winslow. The subsequent 12 reviewers were all sworn-surgeons (certified by St. Côme), including a lone dentist, Laudumiey, surgeon-dentist to His Majesty, Philip V, King of Spain. Fauchard knew that for dentistry to be regarded as a learned profession, and perhaps for Fauchard to be recognized as its leader, he needed the support and approval of the establishment before publishing his book. This is an account of how he attained this endorsement.

Philipp Frank, Richard von Mises, and the Frank-Mises

The theoretical physicist Philipp Frank (1884 1966) and the applied mathematician Richard von Mises (1883 1953) both received their university education in Vienna shortly after 1900 and became friends at the latest during the Great War.They were attached to the Vienna Circle of Logical Positivists and wrote an influential two-part work on the differential and integral equations of mechanics and physics, the Frank-Mises, of 1925 and 1927, with its second edition following in 1930 and 1935.This work originated in the lectures that the mathematician Bernhard Riemann (1826 1866) delivered on partial differential equations and their applications to physical questions at the University of Göttingen between 1854 and 1862, which were edited and published posthumously in1869 by the physicist Karl Hattendorff (1834 1882).The immediate precursor of the Frank-Mises, however, was the extensive revision of Hattendorff’s edition of Riemann’s lectures that the mathematician Heinrich Weber (1842 1913) published in two volumes, the Riemann-Weber, of 1900 and 1901, with its second edition following in 1910 and 1912. I trace this historical lineage, explore the nature and contents of the Frank-Mises, and discuss its complementary relationship to the first volume of the text that the mathematicians Richard Courant (1888 1972) and David Hilbert (1862 1943) published on the methods of mathematical physics in 1924, the Courant-Hilbert,which, when it and its second volume of 1937 were translated into English and extensively revised in 1953 and 1961, eclipsed the classic Frank-Mises.

In a cross-sectional study, the activity, electrophoretic mobility and genotypes of glucose-6-phosphate dehydrogenase (G6PD) were determined among healthy, UAE national school boys from Al-Ain District in the United Arab Emirates, The prevalence of G6PD deficiency in this population sample was 11%. The majority of G6PD-deficient subjects were descendants of Omani, Baluchi or Yemeni migrants. Of 18 deficient subjects, 16 had an enzyme activity of < 10% of normal while 2 had an activity of just above 10%. Electrophoresis was performed on 166 samples and showed that, apart from deficient samples, all had the normal mobility of G6PD type B. Of the 18 deficient subjects, 14 had the B type mobility of G6PD Mediterranean and 4 had the A type mobility of G6PD A-. Genotyping demonstrated that 10 had the Mediterranean mutation while 3 had the A- mutation, consistent with their electrophoretic mobility. Another 3 had the G6PD Aures mutation, recently described as polymorphic in Algeria and Spain. The mutations in the remaining 2 subjects have not yet been identified.

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

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

Modified jeans instability for dust grains in a plasma.

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

The early evolution of Jean Piaget's clinical method.

PubMed

Mayer, Susan Jean

2005-11-01

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

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

NASA Astrophysics Data System (ADS)

Dhiman, Joginder Singh; Sharma, Rajni

2017-12-01

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

Gravity or turbulence? - III. Evidence of pure thermal Jeans fragmentation at ˜0.1 pc scale

2015-11-01

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

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

2004-02-01

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

Jean Rotz and the Marine Chart, 1542

NASA Astrophysics Data System (ADS)

Taylor, E. G. R.

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

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

NASA Astrophysics Data System (ADS)

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

2018-04-01

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

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

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

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

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

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

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

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

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

PubMed

Grīnfelde, Māra

2018-05-24

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

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

Bröer, R; Hofheinz, R

2001-01-01

Subject of this paper is the interpretation of disease as physical evil (malum physicum) by the university professors Philipp Melanchthon (1497-1560) and Caspar Peucer (1525-1602) at Protestant Wittenberg. Melanchthon and Peucer settled the problem of theodicy principally by theological strategies of moralization and compensation. In most cases, therefore, disease resulted from inadequate health behavior, especially drunkenness, furthermore from disdain for medicine and obstruction of divine healing. As a rule, natural factors (e.g. celestial bodies or human affections) only contributed to disease. In general it was caused by free will. In consequence the strategies of depotentiation and functionalization of disease became insignificant resulting in the accentuation of its evil nature. By way of compensation Melanchthon and Peucer stressed the Divine healing of disease. God created the natural remedies and later He created the medical arts by granting heroic virtue to the greatest doctors (Hippocrates, Galen, Avicenna). Moreover the divine Trinity could directly harmonize affections. Thus, God incited a psychosomatical healing within the human organism. As far as physical evil is concerned Lutheran pathology substituted medieval pessimism for therapeutical optimism. Melanchthon and Peucer strived to discipline the patients' behavior and to legitimate the medical arts by God. In this sense their pathology formed part of a program of social and religious stabilization. The academic medicine profited greatly from that program in later years.

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

The authors propose to define as main characterization of plastic reconstructive surgery the conceptual thinking that leads to a rational choice of an operative treatment. Conceptual thinking in plastic surgery started halfway the nineteenth century with the first schematic representations of the operative procedures available at that time, in which Von Ammon and Baumgarten, Szymanowski and Denucé played a prominent role.

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

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

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

Hearing Pygmalion's Kiss: A Scientific Object at the Paris Opéra

Lambert, Kevin

In 1748, in his acte de ballet Pygmalion, composer and music theorist Jean-Philippe Rameau arranged the Paris Opéra orchestra to play "nature's chord," harmonies that reproduced the overtones an expert ear could detect in every natural musical vibrating body. The following year Rameau presented his music theory to the French Royal Academy of Sciences for their endorsement. Disillusionment with the promise of Cartesian mechanics as a source of a unified understanding of nature opened up the possibility that matter might have properties beyond extension and motion, such as aversion, desire, and memory. Speculations about this material sensibility also coincided with increasing claims about the authority of spontaneous emotion and feeling. The experience of music at the opera was a significant resource for claims about the cultural authority of sensibility.

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

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

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

NASA Astrophysics Data System (ADS)

Narayanan, Desika; Davé, Romeel

2012-07-01

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

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

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

2012-05-01

We present a short historical review on the major institutions and figures who contributed to make Paris a renowned centre of physiology and neurology during the XIXth and the first half of the XXth century. We purposely chose to focus on the period 1800-1950, as 1800 corresponds to the actual beginning of neurosciences, and as 1950 marks their exponential rise. Our presentation is divided into four chapters, matching the main disciplines that have progressed and contributed most to the knowledge we have of the brain sciences: anatomy, physiology, neurology, and psychiatry-psychology. The present article is the fourth of the four parts of this review, which deals with the chapter on psychiatry and psychology. When the French Revolution occurred, only a few institutions were taking care of the mentally ill. In the Paris area, these included Maison Royale de Charenton, Les Petites Maisons, and one of the departments of larger hospitals such as Hôtel-Dieu, the Salpêtrière Hospital and Bicêtre Hospital. One of the founders of psychiatry in Paris at that time and thereafter was Philippe Pinel (1745-1826) who was the first to distinguish insane/alienated patients from misfits, beggars, and other vagabonds. During the first half of the XIXth century, his student Jean-Étienne Esquirol (1772-1840) also played a major role with his treatise on mental diseases and the 1838 law and the creation of asylums in all parts of France. Alienists were in general caregivers and learned by themselves. In contrast, at the academic level, the emerging disciplines psychiatry and neurology were very close to each other in the second half of the XIXth century, the best example being Jules Baillarger (1809-1890). The actual development of psychiatry and psychology and the foundation of psychoanalysis later in the XIXth century and in the first half of the XXth century owed much to several European doctors and scientists, particularly those from British institutions and from German

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

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

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

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

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

PubMed

Bertucci, Paola

2005-01-01

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

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

In this perspective special feature, Philippe Walter, Alain Brunelle and colleagues give new insights on the artist's working methods by a careful stateof-the-art imaging ToF-SIMS study of one sample taken on the edge of the painting. This approach allowed for the identification of the pigments used in the painting, their nature and components and those of the ground and preparatory layers, with the identification of the binder(s) and possible other additions of organic materials such as glue. This study paves the way to a wider use of ToF-SIMS for the analysis of ancient cultural heritage artefacts.

However, a copy of Albrecht von Haller's Historia stirpium indigenarum Helvetiae inchoata (1768) in the Lindley Library, Royal Horticultural Society, London, bears Rousseau's name and seems to have been annotated by him. The volume contains the bookplate of Jane Dalton, a cousin to whom Malthus willed "all[his] Botanical Books in which the name of Rousseau is written". Haller was well-known to Rousseau, who while in exile in the Swiss Jura (1763-1765), studied under one of Haller's collaborators, Abraham Gagnebin. Rousseau cited Haller's entry 762 when describing a species of Seseli to the Duchess of Portland.

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

2011-01-01

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

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

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

PubMed

Chong, Gabriel Tse Feng

2012-12-01

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

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

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

PubMed

Hsueh, Yeh

2002-05-01

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

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

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

2016-07-01

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

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

European Glaucoma Society Terminology and Guidelines for Glaucoma, 4th Edition - Part 1Supported by the EGS Foundation

PubMed Central

2017-01-01

Foreword It gives me pleasure to introduce the 4th edition of the EGS Guidelines. The Third edition proved to be extremely successful, being translated into 7 languages with over 70000 copies being distributed across Europe; it has been downloadable, free, as a pdf file for the past 4 years. As one of the main objectives of the European Glaucoma Society has been to both educate and standardize glaucoma practice within the EU, these guidelines were structured so as to play their part. Glaucoma is a living specialty, with new ideas on causation, mechanisms and treatments constantly appearing. As a number of years have passed since the publication of the last edition, changes in some if not all of these ideas would be expected. For this new edition of the guidelines a number of editorial teams were created, each with responsibility for an area within the specialty; updating where necessary, introducing new diagrams and Flowcharts and ensuring that references were up to date. Each team had writers previously involved with the last edition as well as newer and younger members being co-opted. As soon as specific sections were completed they had further editorial comment to ensure cross referencing and style continuity with other sections. Overall guidance was the responsibility of Anders Heijl and Carlo Traverso. Tribute must be made to the Task Force whose efforts made the timely publication of the new edition possible.

Menin, Marco

2012-01-01

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

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

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

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

2010-01-01

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

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

The 11th Anglo-French Physical Acoustics Conference (AFPAC) was held in Brighton, UK on 18-20 January 2012. This event, which is an annual collaboration between the Physical Acoustics Group (PAG) of the Institute of Physics and the Groupe d'Acoustique Physique, Sous-marine et UltraSonore (GAPSUS) of the Société Française d'Acoustique, successfully achieved its main aim of being a small, friendly meeting of high scientific quality, welcoming younger researchers and PhD students and covering a broad range of subjects in Acoustics. The participants heard 44 excellent presentations covering an exciting and diverse range of subjects, from audio acoustics to guided waves in composites and from phononic crystals to ultrasound surgery. As is the custom at these meetings, four prominent invited speakers set the pace for the event; these were Keith Attenborough (The Open University, UK), Claire Prada (Institut Langevin, France), David Moore (University of Nottingham, UK) and Philippe Roux (IS Terre, France). The submission of manuscripts for publication in the proceedings was, as in previous years, on a voluntary basis and in these proceedings we present 11 peer reviewed papers. Due to some unforeseen problems there has been a longer than planned delay in preparing these proceedings, for which the Editors sincerely apologise to the authors and the community.

In May 2012, three European Academies held a conference on the present and future of microbiology. The conference, entitled "The New Microbiology", was a joint effort of the French Académie des sciences, of the German National Academy of Sciences Leopoldina and of the British Royal Society. The organizers - Pascale Cossart and Philippe Sansonetti from the "Académie des sciences", David Holden and Richard Moxon from the "Royal Society", and Jörg Hacker and Jürgen Hesseman from the "Leopoldina Nationale Akademie der Wissenschaften" - wanted to highlight the current renaissance in the field of microbiology mostly due to the advent of technological developments and allowing for single-cell analysis, rapid and inexpensive genome-wide comparisons, sophisticated microscopy and quantitative large-scale studies of RNA regulation and proteomics. The conference took place in the historical Palais de l'Institut de France in Paris with the strong support of Jean-François Bach, Secrétaire Perpétuel of the Académie des sciences.

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

NASA Astrophysics Data System (ADS)

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

2016-03-01

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

BOOK REVIEW: Jean-Charles Houzeau et son temps

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

About five years ago, Arkansas State University created the Arkansas Center for Laser Applications and Science (ArCLAS) with the intention of making it a state-of-the-art facility for laser-based research and optical spectroscopy in the midSouth. Since that time, University and DoD support has lead to the acquisition of numerous laser based spectrometers including a novel three color picosecond system utilized primarily for STIRAP measurements of bulk gas samples. Over the past few months, we have begun collecting near infrared overtone and combination band spectra for the acetylene molecule with a pulsed cavity ringdown laser absorption spectrometer (CRDLAS) as part of the STIRAP support effort. Certainly acetylene has been extensively studied by a number of different spectroscopic methods. During these CRDLAS investigations a 13C_2H_2 band was discovered which we believe has not been previously reported. Here a complete rovibrational analysis of this band will be presented. See for example, Michel Herman, Jacques lievin, Jean Vander Auwera, and Alain Campargue, in Global and Accurate Vibration Hamiltonians from High Resolution Molecular Spectroscopy, Advances in Chemical Physics Volume 108, John Wiley and Sons, NY, NY (1999) and references therein.

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

NASA Technical Reports Server (NTRS)

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

2011-01-01

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

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.

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

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

Gerhardt, Philipp (The University of Michigan, Ann Arbor), and Jean A. Judge. Porosity of isolated cell walls of a yeast and a bacillus. J. Bacteriol. 87:945-951. 1964.-Decagram masses of cell walls were isolated from Saccharomyces cerevisiae and Bacillus megaterium; their porosity was examined by measuring the extent of uptake with polyethylene glycols and dextrans varying in molecular weight from 62 to 2,000,000. The results indicated that both walls are heteroporous. The near equality of extrapolated water-uptake values and determined moisture contents suggested that water in the cell walls is mainly free for distribution of solutes. Polymers with molecular weights of 4,500 and above were excluded by the yeast walls, and those with molecular weights of 57,000 were excluded by the bacillus walls; from these results, maximal openings of 36 and 107 A, respectively, were calculated. Electron micrographs of shadowed, stained, and sectioned walls revealed fine structure not inconsistent with heteroporosity, but the predicted openings were not seen. Altogether, in structure and permeability behavior, the cell walls were like a random meshwork of cross-linked macromolecular strands.

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

2018-06-01

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

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

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

The Earth Summit: a vision shared. An interview with Jean-Claude Faby.

Hoeffel, P H

1992-01-01

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.

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

PubMed

Henry, John

2011-01-01

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

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

PubMed

Bogousslavsky, Julien; Boller, François

2013-01-01

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

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

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

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

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

In 1840 the Dresden physician and professor at the Chirurgisch-medicinischen Akademie Johann Ludwig Choulant (1791-1861)--at that time one of the most well-known experts in history of medicine--received a German translation of the Fracastoro syphilis poem. This philological piece goes back to the physician and surgeon Ernst Philipp Heinrich Späth (1809-1856) who had already worked on the poem of Girolamo Fracastoro (1478-1553) and its translation in the 1830s. Späth referred to the 1830 Latin publication of Choulant's syphilis poem--which he later used as the literary basis for his adaptation. Späth had acquired his knowledge of philology at a theology seminar in Urach and during his theology studies inTübingen. However, he quit his theology studies to switch to medicine. In 1832 he took the state examination and received a doctorate of medicine and surgery. In the very same year he established a practice as general practitioner, surgeon and obstetrician in Esslingen to eventually be appointed chief surgeon at the Esslingen hospital. Besides his work as a physician Späth was also a publisher, e.g. he also became the editor of the first local Esslingen newspaper. Späth's translation, apparently finished almost completely already in 1837, was sent to Choulant to ask his opinion in 1840. This version seems to be not only one of the rarest but also earliest German adaptations. Although hardly any other medical poem was so often translated into modern languages as Fracastoro's "Syphilidis sive morbi gallici libri III", there are only three German publications mentioned in a 1935 bibliography with the first complete German translation being published in 1858. Späth's script, however, has never been published and has remained in the handwritten estate of Choulant in Dresden ever since.

Integrating the progress that has been made on a daily basis since it was jointly commissioned in 2013 by the French National Academy of Medicine (Biotechnology Committee XX, Prof Emmanuel-Alain Cabanis) and the Technologies Academy (Pr Jean de Kervasdoué), this report, covering such a vast subject, can only represent one step in a long process. Summarized here in a volume compatible with the Bulletin, it makes reference to the full report (52 pages ; 22 pages of text, 4 pages of references, a 20-page glossary for physicians, plus 522 figures spanning 6 pages), which is available on the Academy's website. The six chapters first define "health" (WHO) and "informatics" and provide a brief history. The first chapter, on technologies, is divided into "bad" news (cybercrime, ecological risks) and advances relevant to health. The next four chapters describe the contribution of digitization to patient management, ranging from "fragile" individuals (from the gamete to old age and dependency) to healthy subjects trained to work in hostile situations (scuba diving to space exploration), and finally research. The last chapter proposes 7 areas for progress: expansion of the national imaging and communications platforms, stimulation of the medical robotics industry, extension of telemedicine to all medical and surgical specialties, support for drug dispensing and therapeutic education, and foundation of a European portal for m-health certification, research prioritization according to multiyear health plans, and reinforcement of mathematic education, starting in primary school (see: "La main à la pâte" ("Going hands-on").

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

2014-01-01

We aimed to study the anatomical distribution, severity and outcome of hospitalised interpersonal violence-related injured patients in Al-Ain, United Arab Emirates so as to give recommendations regarding the magnitude of this problem, its causes and priorities of prevention. Data were retrieved from Al-Ain Hospital Trauma Registry, which was prospectively collected over three years. There were 75 patients (males = 85.3%) having a mean age of 30 years. Eighty-one percent had blunt trauma. The estimated annual injury hospitalisation of interpersonal violence in Al-Ain city was 6.7 per 100,000 population. Females were significantly more injured by a family member (p = 0.02), at home (p = 0.005), and had more severe injuries (p = 0.003). There was a trend for children less than 18 years old to have more penetrating trauma (p = 0.06) and to be injured by a family member (p = 0.09). There was only one case of woman sexual assault and two cases of child abuse. The mean (SD) hospital stay was 7.87 (14.1) days. Less than 3% (n = 2) were admitted to the intensive care unit with no deaths. In conclusion, the majority of patients in our study had minor injuries. Nevertheless, the psychological impact may be major. This highlights the need to develop suitable mental health services in support of victims of interpersonal violence.

"Advice to the medical students in my service": the rediscovery of a golden book by Jean Hamburger, father of nephrology and of medical humanities.

PubMed

Barbara, Piccoli Giorgina

2013-03-15

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

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

2014-05-01

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

Costs and deaths of landslides in Europe

Landslides cause human and large economic losses worldwide and also in Europe. However, the quantification of associated costs and deaths is highly underestimated and still incomplete, thus the estimation of landslide costs and risk is still rather ambitious. Hence, in this study a spatio-temporal analysis of fatal landslides is presented for 27 European countries from 1995-2014. These landslides are mainly concentrated in mountainous areas. A total of 1370 fatalities are reported resulting from 476 landslides. The highest fatalities with 335 are observed in Turkey. In general, an increasing trend of fatal landslides is recognized starting in 2008. The latter is almost certainly triggered by an increase in natural extreme events such as storms (i.e. heavy rainfall) and floods. The highest annual economic loss is observed in Italy with 3.9 billion Euro per year. In contrast, in Germany the annual total loss is only about 0.3 billion Euro. The results of this study serves as an initial baseline information for further risk studies integrating landslide locations, local land use data, cost data, and will therefore certainly support the studied countries to better protect their citizens and assets.

2018-06-26

In awake craniotomy, it is possible to temporarily inactivate regions of the brain using direct electrical stimulation, while the patient performs neuropsychological tasks. If the patient shows decreased performance in a given task, the neurosurgeon will not remove these regions, so as to maintain all brain functions. The objective of our study was to describe our experience of using a virtual reality (VR) social network during awake craniotomy and discuss its future applications for perioperative mapping of nonverbal language, empathy, and theory of mind. This was a single-center, prospective, unblinded trial. During wound closure, different VR experiences with a VR headset were proposed to the patient. This project sought to explore interactions with the neuropsychologist's avatar in virtual locations using a VR social network as an available experience. Three patients experienced VR. Despite some limitations due to patient positioning during the operation and the limitation of nonverbal cues inherent to the app, the neuropsychologist, as an avatar, could communicate with the patient and explore gesture communication while wearing a VR headset. With some improvements, VR social networks can be used in the near future to map social cognition during awake craniotomy.

Why did we elaborate an entangled photons experiment in our engineering school?

NASA Astrophysics Data System (ADS)

Jacubowiez, Lionel; Avignon, Thierry

2005-10-01

We will describe a simple setup experiment that allows students to create polarization-entangled photons pairs. These photon pairs are in an entangled state first described in the famous 1935 article in Phys.Rev by Einstein-Podolsky-Rosen, often called E.P.R. state. Photons pairs at 810 nm are produced in two nonlinear crystals by spontaneous parametric downconversion of photons at 405 nm emitted by a violet laser diode. The polarization state of the photons pairs is easily tunable with a half-wave plate and a Babinet compensator on the laser diode beam. After having adjusted the polarization-entangled state of the photon pairs, our students can perform a test of Bell's inequalities. They will find the amazing value for the Bell parameter between 2.3 and 2.6, depending on the quality of the adjustments of the state of polarization. The experiments described can be done in 4 or 5 hours. What is the importance of creating an entangled photons experiment for our engineering students? First of all, entanglement concept is clearly one of the most strikingly nonclassical features of quantum theory and it is playing an increasing role in present-day physics. But in this paper, we will emphasise the experimental point of view. We will try to explain why we believe that for our students this lab experiment is a unique opportunity to deal with established concepts and experimental techniques on polarization, non linear effects, phase matching, photon counting avalanche photodiodes, counting statistics, coincidences detectors. Let us recall that the first convincing experimental violations of Bell's inequalities were performed by Alain Aspect and Philippe Grangier with pairs of entangled photons at the Institut d'Optique between 1976 and 1982. Twenty five years later, due to recent advances in laser diode technology, new techniques for generation of photon pairs and avalanche photodiodes, this experiment is now part of the experimental lab courses for our students.

Ignaz Philipp Semmelweis, the prophet of bacteriology.

Wyklicky, H; Skopec, M

1983-01-01

Although by 1931 I. Ph. Semmelweis' achievements and the tragedy of his life had been given their due place in the history of mankind, Alexander Fränkel, formerly Theodor Billroth's assistant and later his biographer, critically stated that the discoverer of the causes of puerperal fever should have defended his discovery with facts rather than with fanaticism. It was only a few years after Semmelweis' death, for instance, that Billroth made laborious experiments. Billroth's work on Coccobacteria had important implications and even influenced Robert Koch, although his hypotheses did not really predict the pathogenic and specific nature of microbes. In 1847 Semmelweis postulated his theory; ie, that the pathological-anatomical changes which he observed in the bodies of the women who died in childbed, in their newborn infants, and in the autopsy findings on his friend Jakob Kolletschka were an entity, morphologically and clinically. He summed them up under the concept of pyemia. Even though Semmelweis was continually abhorred by the evident statistics and would have been able to prove his discovery through animal experiments, he primarily took to the pen to defend his opinion vehemently. Only the clinical facts proved him right during his lifetime; the triumph of bacteriology which began after his death made him not only the "savior of mothers" but also a genial ancestor of bacteriology.

Modelling the oscillations of the thermocline in a lake by means of a fully consistent and conservative 3D finite-element model with a vertically adaptive mesh

Vertical discretisation is crucial in the modelling of lake thermocline oscillations. For finite element methods, a simple way to increase the resolution close to the oscillating thermocline is to use vertical adaptive coordinates. With an Arbitrary Lagrangian-Eulerian (ALE) formulation, the mesh can be adapted to increase the resolution in regions with strong shear or stratification. In such an application, consistency and conservativity must be strictly enforced. SLIM 3D, a discontinuous-Galerkin finite element model for shallow-water flows (www.climate.be/slim, e.g. Kärnä et al., 2013, Delandmeter et al., 2015), was designed to be strictly consistent and conservative in its discrete formulation. In this context, special care must be paid to the coupling of the external and internal modes of the model and the moving mesh algorithm. In this framework, the mesh can be adapted arbitrarily in the vertical direction. Two moving mesh algorithms were implemented: the first one computes an a-priori optimal mesh; the second one diffuses vertically the mesh (Burchard et al., 2004, Hofmeister et al., 2010). The criteria used to define the optimal mesh and the diffusion function are related to a suitable measure of shear and stratification. We will present in detail the design of the model and how the consistency and conservativity is obtained. Then we will apply it to both idealised benchmarks and the wind-forced thermocline oscillations in Lake Tanganyika (Naithani et al. 2002).

Attention deficit hyperactivity disorder (ADHD) in a 19th century children's book.

PubMed

Thome, Johannes; Jacobs, Kerrin A

2004-08-01

Attention deficit hyperactivity disorder (ADHD) is a major mental disorder in children. Presently, its pathogenesis and treatment as well as its role in adult psychiatry are subjects of heated debate. As early as 1846, the typical symptoms of ADHD were described by Heinrich Hoffmann, a physician who later founded the first mental hospital in Frankfurt. Interestingly, his description was published in a children's book entitled "Struwwelpeter" which he had designed for his 3-year-old son Carl Philipp. The symptomatology is impressively depicted in the colourfully illustrated story of "Zappel-Philipp" ("Fidgety Philip"), probably the first written mention of ADHD by a medical professional. This clearly shows that the diagnosis of ADHD is not an "invention" of modern times.

To describe the epidemiology of a leading cause of childhood mortality in Al-Ain, United Arab Emirates (UAE)--injury. To examine trends across types of injury, as well as the mechanisms of injury leading to death, by age groups, gender, citizenship, and explore mortality rates and make global comparisons. This is a retrospective, descriptive, statistical analysis of unlinked hospital data. Al-Ain and Tawam Hospitals, and Preventive Medicine Department, Al-Ain, United Arab Emirates. All cases that met the conditions established for the study: fell within the age group of 0 to 14 years, suffered from injuries, and were admitted to either Al-Ain or Tawam hospitals and subsequently died within the studied time period of 1 January 1995 to 31 December 2004. A total of 7204 deaths were reported in children below 15 years during the studied time period. Of these cases, 2150 children died due to injury, comprising 29.8% of total deaths. Further analysis showed that road traffic injuries were the most frequent cause of injury leading to death (68.3%). Overall injury death rates were higher in non-citizens (54.5%) than in citizens (45.5%); and males had a higher incidence, specifically a 2.1:1 ratio, than females. Children 5 to 14 years had the highest frequency of injury deaths. Overall, injury mortality rates exhibited a decreasing, though fluctuating, trend during the studied period at a rate that is comparable to those in other developed nations such as New Zealand and USA. The present study reveals that the burden of injury deaths among children below 15 years is significant; and injuries exist in every form and affect every age group, and gender. The high burden of injuries on children in the UAE demands the attention of the health community, including policy makers. An understanding of the trends such as those presented in this study, for instance that injuries from road traffic are prominent, will assist in the development of interventions to address this growing

Hierarchical Fragmentation in the Perseus Molecular Cloud: From the Cloud Scale to Protostellar Objects

Pokhrel, Riwaj; Myers, Philip C.; Dunham, Michael M.; Stephens, Ian W.; Sadavoy, Sarah I.; Zhang, Qizhou; Bourke, Tyler L.; Tobin, John J.; Lee, Katherine I.; Gutermuth, Robert A.; Offner, Stella S. R.

We present a study of hierarchical structure in the Perseus molecular cloud, from the scale of the entire cloud (≳ 10 pc) to smaller clumps (∼1 pc), cores (∼0.05–0.1 pc), envelopes (∼300–3000 au), and protostellar objects (∼15 au). We use new observations from the Submillimeter Array (SMA) large project “Mass Assembly of Stellar Systems and their Evolution with the SMA (MASSES)” to probe the envelopes, and recent single-dish and interferometric observations from the literature for the remaining scales. This is the first study to analyze hierarchical structure over five scales in the same cloud complex. We compare the number of fragments with the number of Jeans masses in each scale to calculate the Jeans efficiency, or the ratio of observed to expected number of fragments. The velocity dispersion is assumed to arise either from purely thermal motions or from combined thermal and non-thermal motions inferred from observed spectral line widths. For each scale, thermal Jeans fragmentation predicts more fragments than observed, corresponding to inefficient thermal Jeans fragmentation. For the smallest scale, thermal plus non-thermal Jeans fragmentation also predicts too many protostellar objects. However, at each of the larger scales thermal plus non-thermal Jeans fragmentation predicts fewer than one fragment, corresponding to no fragmentation into envelopes, cores, and clumps. Over all scales, the results are inconsistent with complete Jeans fragmentation based on either thermal or thermal plus non-thermal motions. They are more nearly consistent with inefficient thermal Jeans fragmentation, where the thermal Jeans efficiency increases from the largest to the smallest scale.

The Complicated Geologic History of Asteroid 4 Vesta

NASA Astrophysics Data System (ADS)

Taylor, G. J.

2009-06-01

Planetary scientists are pretty sure that almost all of the HED meteorites come from the fourth-largest asteroid, 4 Vesta. HED stands for the three types of rocks that make up the group. As cosmochemists have studied the meteorites over the years, their view of the geologic history of the asteroid has become progressively more complicated. Jean-Alix Barrat and Marcel Bohn (CNRS and University of Brest, France), Philippe Gillet (CNRS and Ecole Normale Supérieure de Lyon, France), and Akira Yamaguchi (National Institute of Polar Research, Tokyo, Japan) have found that Vesta is even more complicated--and interesting--than we thought. Barrat and his colleagues analyzed impact-produced glass spherules and fragments in several howardites (mixtures of the two other main types, eucrites and diogenites). Not surprisingly, most of the glasses have compositions similar to eucrites, which are basalts, or mixtures of them with diogenites, but a few are surprisingly rich in silicon and potassium (expressed as the percentages of SiO2 and K2O, respectively). In fact, the concentrations of these oxides are similar to granites, compositionally far from basalt. Their manufacture requires extensive crystallization of magma. Combined with a more subtle variation among the basalts, the emerging picture is one that includes formation of a basaltic crust, partial melting of parts of the crust, mixing of those melts with some (not all) magmas as they migrated through the crust, and extensive crystallization of magma bodies to produce residual magma resembling granites. On top of that, Vestan rocks were thermally metamorphosed and battered and mixed by impacts. A pretty complicated little planetary body!

Objectives: To provide early data regarding clinical utility of dabigatran in Al-Ain, United Arab Emirates (UAE). Methods: This was an ethics approved retrospective cross sectional study. We retrieved a total of 76 patients who were using dabigatran from September to December 2014 in the Cardiology Clinic at Al-Ain Hospital, Al-Ain, UAE. The primary analysis was designed to test the frequency of bleeding events (rate) with dabigatran 75, 110, and 150 mg. Results: The mean age ± standard deviation of cohort was 67.9 ± 1.5 years (range; 29-98 years), composed of males (52.6%) with mean age of 66.3 ± 1.7 years, and females (47.4%) with mean age of 69.6 ± 1.1 years. The highest age group was those between 61-80 years (60.5%). Most comprised the age strata of ≤75 years (73.7%). The main indication for dabigatran use was atrial fibrillation. The rate of bleeding with dabigatran was 18/76 (23.7%), and melena was the leading cause of bleeding 8/76 (10.7%). The hospitalization rate was 67.1%, dabigatran withdrawal rate was 0.01%, and mortality rate was 6.5%. The cohort had exhibited incidences of minor bleeding with one fatal major bleeding, high co-morbidities, admission, and readmission, which was not directly linked to dabigatran. We did not identify any relation of death due to dabigatran. Conclusion: Dabigatran is a suitable alternative to warfarin obviating the need for repetitive international normalized ratio monitoring, however, it may need plasma drug monitoring. PMID:26593161

Pierre Jean Georges Cabanis (1757-1808): an early nineteenth century source for the concept of nervous energy in European behavioral neurosciences.

PubMed

Turgeon, Y; Whitaker, H A

2000-01-01

The nineteenth century witnessed many advances in neuroscientific concepts. Among the notable are Charles Bell's (1774-1842) and François Magendie's (1783-1855) identification of sensory and motor pathways, Thomas Henry Huxley's (1825-1895) elaboration of evolutionary theory in the context of comparative neuroanatomy, and Emile Du Bois-Reymond's (1818-1896) and Hermann von Helmholtz's (1821-1894) work in experimental neurophysiology and on the concept of nervous energy. In Germany, the idea that the nervous system consisted of two elements, one that generated nervous energy and another that conducted it throughout the body, had wide currency in mid-nineteenth century. In France, Pierre Jean Georges Cabanis (1757-1808), physician, philosopher, and one of the founders of modern psychophysiology, argued that the brain is the part of the body in which electricity is stored. In his Rapports du Physique et du Moral de l'Homme, published between 1796 and 1802 (translated into German under the title Verhältnis der Seele zum Körper (1808)), Cabanis proposed new ideas on brain function, on the brain's own sensibility, on the concept of will, and on the chemical basis of nervous activity. In the Rapports Cabanis proposed a theory of how brain and nerves relate to thought and behavior. Foreshadowing later developments in neuropsychology, he suggested that different parts of the nervous system have separate functions. Despite the fact that Cabanis had many interesting ideas about brain function, he has been largely ignored by historians of neuroscience; e. g., he is mentioned briefly in Clark and Jacyna (1989), in only two footnotes in Neuburger (1897/1981), and not at all in Finger (1994). Cabanis's far-reaching theory of how the brain works helped shape understanding of the general notion of nervous energy in nineteenth-century European neuroscience.

[WILD MAMMALS OF THE GRAND DUCHY OF LITHUANIA IN THE WORKS OF JEAN-EMMANUEL GILIBERT].

PubMed

Samojlik, Tomasz; Daszkiewicz, Piotr

2015-01-01

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

Local probing by use of transparent model materials

NASA Astrophysics Data System (ADS)

Philippe, P.

2017-12-01

The present contribution emphasizes on two distinct examples the benefit with using transparent materials that enable direct visualization within different types of model systems. Our first use of transparent materials investigates the elementary mechanisms involved in soil erosion based on three key ingredients: a) cohesive model materials (i.e. glass beads bonded by solid bridges); b) optical techniques (Refractive Index Matching and Planar Laser Induced Fluorescence [1,2]) ; c) specific mechanical tests to estimate the mechanical strength of the solid bonds. Then, critical shear-stress at erosion onset can be related to tensile strength considering an extension of the classical Shields' number [3,4].Our second example uses a transparent elasto-visco-plastic fluid (Carbopol) as a model of debris flows. Different geometrical configurations allow for an accurate investigation of the flow over an obstacle [5] or a cavity [6], inducing the existence of a dead-zone and consequently of a frontier between solid-like and fluid-like regions that is of particular relevance for debris flows mobilization and deposition. Practically, the hydrodynamics of the flow is investigated by means of high-resolution optical velocimetry (PIV) and underlines a non-monotonous evolution of the shear rate, which increases from zero at the solid-liquid interface, passes through a peak (sometimes leveling off at its maximum value), and returns to zero in a plug zone sufficiently far above the cavity or the obstacle.

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

PubMed

Bogousslavsky, Julien; Walusinski, Olivier; Veyrunes, Denis

2009-01-01

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. 2009 S.

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.

Effect of fine dust particles and finite electron inertia of rotating magnetized plasma

NASA Astrophysics Data System (ADS)

Kumar, V.; Sutar, D. L.; Pensia, R. K.; Sharma, S.

2018-05-01

A theoretical investigation has been made of the effect of fine dust particles, viscosity and electron inertia on Jeans instability in a self-gravitating magnetized rotating plasma. The MHD model is used to formulate the problem in which a general dispersion relation. A general dispersion relation is obtained from the linearized perturbation equations using the normal mode analysis method. The analytical expressions of the growth rate of Jeans instability are obtained for the longitudinal and transverse mode of propagation. The present result shows that the Jeans criterion of instability is modified due to the presence of viscosity, rotation, and magnetic field.

LIFTING THE DUSTY VEIL WITH NEAR- AND MID-INFRARED PHOTOMETRY. III. TWO-DIMENSIONAL EXTINCTION MAPS OF THE GALACTIC MIDPLANE USING THE RAYLEIGH-JEANS COLOR EXCESS METHOD

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

Thermal evolution of magma reservoirs in the shallow crust and incidence on magma differentiation: the St-Jean-du-Doigt layered intrusion (Brittany, France)

NASA Astrophysics Data System (ADS)

Barboni, M.; Bussy, F.; Ovtcharova, M.; Schoene, B.

2009-12-01

Understanding the emplacement and growth of intrusive bodies in terms of mechanism, duration, thermal evolution and rates are fundamental aspects of crustal evolution. Recent studies show that many plutons grow in several Ma by in situ accretion of discrete magma pulses, which constitute small-scale magmatic reservoirs. The residence time of magmas, and hence their capacities to interact and differentiate, are controlled by the local thermal environment. The latter is highly dependant on 1) the emplacement depth, 2) the magmas and country rock composition, 3) the country rock thermal conductivity, 4) the rate of magma injection and 5) the geometry of the intrusion. In shallow level plutons, where magmas solidify quickly, evidence for magma mixing and/or differentiation processes is considered by many authors to be inherited from deeper levels. We show however that in-situ differentiation and magma interactions occurred within basaltic and felsic sills at shallow depth (0.3 GPa) in the St-Jean-du-Doigt bimodal intrusion, France. Field evidence coupled to high precision zircon U-Pb dating document progressive thermal maturation within the incrementally built laccolith. Early m-thick mafic sills are homogeneous and fine-grained with planar contacts with neighbouring felsic sills; within a minimal 0.5 Ma time span, the system gets warmer, adjacent sills interact and mingle, and mafic sills are differentiating in the top 40 cm of the layer. Rheological and thermal modelling show that observed in-situ differentiation-accumulation processes may be achieved in less than 10 years at shallow depth, provided that (1) the differentiating sills are injected beneath consolidated, yet still warm basalt sills, which act as low conductive insulating screens, (2) the early mafic sills accreted under the roof of the laccolith as a 100m thick top layer within 0.5 My, and (3) subsequent and sustained magmatic activity occurred on a short time scale (years) at an injection rate of ca. 0

The Exchange-Correlation Field Effect over the Magnetoacoustic-Gravitational Instability in Plasmas

NASA Astrophysics Data System (ADS)

Rasheed, A.; Jamil, M.; Jung, Young-Dae; Sahar, A.; Asif, M.

2017-09-01

Jeans instability with magnetosonic perturbations is discussed in quantum dusty magnetoplasmas. The quantum and smaller thermal effects are associated only with electrons. The quantum characteristics include exchange-correlation potential, recoil effect, and Fermi degenerate pressure. The multifluid model of plasmas is used for the analytical study of this problem. The significant contribution of electron exchange is noticed on the threshold value of wave vector and Jeans instability. The presence of electron exchange and correlation effects reduce the time to stabilise the phenomenon of self-gravitational collapse of massive species. The results of Jeans instability by magnetosonic perturbations at quantum scale help to disclose the details of the self-gravitating dusty magnetoplasma systems.

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

As science communicators dealing with astronomy we often find a strong interest amongst the public in astrology - how the stars and planets directly affect our individual lives. Nowadays astrology is at odds with the scientific nature of astronomy, but this has not always been the case. Presented here is a background to astrology, to give a deeper understanding of where it has come from and why it has such an enduring place in all forms of global media.

Throughout paintings, engravings, and photography, Charcot's face and his life at the Salepêtrière have become widely known. More importantly, his biographers and those who wrote about their firsthand experiences with Charcot have brought to life his authority and his penetrating eye. Charcot held his students, his patients, and all those in close contact with him under a despotic rule. His shyness and emotions hid behind a cold and impenetrable mask. Much has been written about Charcot's life at the Salpêtrière. He transformed the old hospice into an institute of neurology considered internationally as a model, and its fame attracted visitors and patients from around the world. He formed a school at the Salpêtrière composed of his many students. These young men gathered each Tuesday evening in the luxurious reception halls of his mansion on Boulevard Saint-Germain. There they mixed with writers, artists, and politicians who were firmly republican and anticlerical. There is only information on Charcot's early years other than the major dates of his career and a few legends. Arriving at the Salpêtrière in 1862, he created the foundations of neurology over the next decade by applying the anatomoclinical method. Built on the traditions of the French anamatopathological method, his system was adapted by Charcot to incorporate the new advances in microscopy and cellular pathology. Later in his career, he also directed a scientific effort towards psychophysiologic explorations of hysteria and hypnosis, some inciting severe criticism. This judgement has been revised and in its place there remains the boldness of an innovative mind. His neurological achievement remains undisputed.(ABSTRACT TRUNCATED AT 250 WORDS)

Effects of Hall current and electrical resistivity on the stability of gravitating anisotropic quantum plasma

NASA Astrophysics Data System (ADS)

Bhakta, S.; Prajapati, R. P.

2018-02-01

The effects of Hall current and finite electrical resistivity are studied on the stability of uniformly rotating and self-gravitating anisotropic quantum plasma. The generalized Ohm's law modified by Hall current and electrical resistivity is used along with the quantum magnetohydrodynamic fluid equations. The general dispersion relation is derived using normal mode analysis and discussed in the parallel and perpendicular propagations. In the parallel propagation, the Jeans instability criterion, expression of critical Jeans wavenumber, and Jeans length are found to be independent of non-ideal effects and uniform rotation but in perpendicular propagation only rotation affects the Jeans instability criterion. The unstable gravitating mode modified by Bohm potential and the stable Alfven mode modified by non-ideal effects are obtained separately. The criterion of firehose instability remains unaffected due to the presence of non-ideal effects. In the perpendicular propagation, finite electrical resistivity and quantum pressure anisotropy modify the dispersion relation, whereas no effect of Hall current was observed in the dispersion characteristics. The Hall current, finite electrical resistivity, rotation, and quantum corrections stabilize the growth rate. The stability of the dynamical system is analyzed using the Routh-Hurwitz criterion.

Two notions of conspicuity and the classification of phyllotaxis.

PubMed

Reick, Christian H

2002-04-07

Invoking cylindrical Bravais lattices, Adler (1974, 1977) proposed a mathematically precise definition for the botanical classification of phyllotaxis. It is based on opposed pairs of parastichy families, that are conspicuous and visible. Jean (1988) generalized this concept to non-opposed pairs of parastichy families. In the present paper it is shown that this generalization implies a notion of conspicuity different from Adler's. This is made obvious by redefining the key terms of the two approaches. Both classifications are well defined. For Adler's, this is shown by presenting a general proof for his conjecture that conspicuous (in the sense of Adler) opposed pairs of parastichy families are visible. There are indications that in applications to models of phyllotaxis (van Iterson model, inhibitor models) their solutions are better characterized by Jean's classification. The differences between Adler's and Jean's classification show up only in very rare cases, so that the practice of pattern determination is only insignificantly touched by the present results. It turns out that the widely used contact parastichy method to determine phyllotactic patterns gives results according to Jean's classification rather than Adler's.

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

NASA Technical Reports Server (NTRS)

Mcclelland, J.; Silk, J.

1977-01-01

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

A 3-bp deletion (ΔF508) in the cystic fibrosis (CF) gene is the mutation on the majority of CF chromosomes. We studied 112 CF families from North American populations of French ancestry: French-Canadian families referred from hospitals in three cities in Quebec and from the Saguenay-Lac St. Jean region of northeastern Quebec and Acadian families living in Louisiana. ΔF508 was present on 71%, 55%, and 70% of the CF chromosomes from the major-urban Quebec, Saguenay-Lac St. Jean, and Louisiana Acadian families, respectively. A weighted estimate of the proportion of ΔF508 in the French-Canadian patient population of Quebec was 70%. We found that 95% of the CF chromosomes with ΔF508 had D7S23 haplotype B, the most frequent haplotype on CF chromosomes. In the Saguenay-Lac St. Jean families, 86% of the CF chromosomes without ΔF508 had the B haplotype, compared with 31% for the major-urban Quebec and Louisiana Acadian families. The incidence of CF in the Saguenay-Lac St. Jean population was 1/895 live-born infants. PMID:2220803

The STS-111 mission, the 14th Shuttle mission to visit the International Space Station (ISS), was launched on June 5, 2002 aboard the Space Shuttle Orbiter Endeavour. On board were the STS-111 and Expedition Five crew members. Astronauts Kerneth D. Cockrell, commander; Paul S. Lockhart, pilot; and mission specialists Franklin R. Chang-Diaz and Philippe Perrin were the STS-111 crew members. Expedition Five crew members included Cosmonaut Valeri G. Korzun, commander; Astronaut Peggy A. Whitson and Cosmonaut Sergei Y. Treschev, flight engineers. Three space walks enabled the STS-111 crew to accomplish the delivery and installation of the Mobile Remote Servicer Base System (MBS), an important part of the Station's Mobile Servicing System that allows the robotic arm to travel the length of the Station, which is necessary for future construction tasks. In this photograph, Astronaut Philippe Perrin, representing CNES, the French Space Agency, participates in the second scheduled EVA. During the space walk, Perrin and Chang-Diaz attached power, data, and video cables from the ISS to the MBS, and used a power wrench to complete the attachment of the MBS onto the Mobile Transporter (MT).

Dynamical Effects on the Escape of H and D: Martian Water Reservoirs

NASA Technical Reports Server (NTRS)

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

2002-01-01

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

Numerical Simulation of Self-gravitational Instability of Isothermal Gaseous Slab Under High External Pressure

NASA Astrophysics Data System (ADS)

Miyaji, S.; Umekawa, M.; Matsumoto, R.; Yoshida, T.

1996-05-01

Gaseous slab is formed with shock waves from super novae, collision of interstellar clouds, etc. When the mass in the Jeans scale is more than Jeans mass, the slab fragments into many clumps by gravitational instability. But in high external pressure environment, even the slab which is stable against Jeans mode can fragment(Elmegreen and Elmegreen 1978).This phenomenon results from incompressible mode instability(Lubow and Pringle 1993). These works are by linear analysis. We study numerically this isothermal gaseous slab which is formed by high external pressure and whose thickness is much smaller than its scale height. We assume self-gravitational fluid, and use two dimensional flux split method. Our model size is taken about the scale of linear maximum growth rate wave length and its five times length, which is an example of much longer than the maximum growth rate wave length. When the incompressible mode instability takes place, it becomes clumps. Each mass of the clumps is less than the Jeans mass. Then the clumps approach each other by gravitational interaction to form bigger clumps. In the presentation we will show results of numerical simulation and discuss about the interaction of fragments on star formation or initial mass function.

It is an interesting aspect of a debate about the cultural and social value of science which shook the scientific comunity as well as the public. Ideological and religious belief concurred with Millikan's scientific work in designing this unified perspective. This American optimism and progressive ideology of science clashed with Jeans' and Eddington's claim of the cosmological validity of the second law of thermodynamics.

In the early part of the 18th century the mechanization of Petit's tourniquet is one of the most outstanding medical inventions. During more than a century that tool without any noticeable change was in the surgical boxes in all countries. As the mechanic Peron has been intensely working to handcraft the device with the utmost urgency Petit's tourniquet could have become that of Petit and Peron.

Accurate accounts of both living and fossil mammal communities are critical for creating biodiversity inventories and understanding patterns of changing species diversity through time. We combined data from from14 new fossil localities with literature accounts and museum records to document the bat biodiversity of Haiti through time. We also report an assemblage of late-Holocene (1600–600 Cal BP) bat fossils from a montane cave (Trouing Jean Paul, ~1825m) in southern Haiti. The nearly 3000 chiropteran fossils from Trouing Jean Paul represent 15 species of bats including nine species endemic to the Caribbean islands. The fossil bat assemblage from Trouing Jean Paul is dominated by species still found on Hispaniola (15 of 15 species), much as with the fossil bird assemblage from the same locality (22 of 23 species). Thus, both groups of volant vertebrates demonstrate long-term resilience, at least at high elevations, to the past 16 centuries of human presence on the island. PMID:28574990

Introduction Diabetes self-management education is a cornerstone of diabetes care. However, many diabetics in the United Arab Emirates (UAE) lack sufficient knowledge about their disease due to illiteracy. Thus, before considering any possible intervention it was imperative to assess present knowledge, attitudes, and practices of patients towards the management of diabetes. Methods A random sample of 575 DM patients was selected from diabetes outpatient's clinics of Tawam and Al-Ain hospitals in Al-Ain city (UAE) during 2006–2007, and their knowledge attitude and practice assessed using a questionnaire modified from the Michigan Diabetes Research Training Center instrument. Results Thirty-one percent of patients had poor knowledge of diabetes. Seventy-two had negative attitudes towards having the disease and 57% had HbA1c levels reflecting poor glycemic control. Only seventeen percent reported having adequate blood sugar control, while 10% admitted non-compliance with their medications. Knowledge, practice and attitude scores were all statistically significantly positively, but rather weakly, associated, but none of these scores was significantly correlated with HbA1c. Conclusions The study showed low levels of diabetes awareness but positive attitudes towards the importance of DM care and satisfactory diabetes practices in the UAE. Programs to increase patients' awareness about DM are essential for all diabetics in the UAE in order to improve their understanding, compliance and management and, thereby, their ability to cope with the disease.

This report summarizes the work performed under the project project Next-Generation Algo- rithms for Assessing Infrastructure Vulnerability and Optimizing System Resilience. The goal of the project was to improve mathematical programming-based optimization technology for in- frastructure protection. In general, the owner of a network wishes to design a network a network that can perform well when certain transportation channels are inhibited (e.g. destroyed) by an adversary. These are typically bi-level problems where the owner designs a system, an adversary optimally attacks it, and then the owner can recover by optimally using the remaining network. This project funded three years ofmore » Deon Burchett's graduate research. Deon's graduate advisor, Professor Jean-Philippe Richard, and his Sandia advisors, Richard Chen and Cynthia Phillips, supported Deon on other funds or volunteer time. This report is, therefore. essentially a replication of the Ph.D. dissertation it funded [12] in a format required for project documentation. The thesis had some general polyhedral research. This is the study of the structure of the feasi- ble region of mathematical programs, such as integer programs. For example, an integer program optimizes a linear objective function subject to linear constraints, and (nonlinear) integrality con- straints on the variables. The feasible region without the integrality constraints is a convex polygon. Careful study of additional valid constraints can significantly improve computational performance. Here is the abstract from the dissertation: We perform a polyhedral study of a multi-commodity generalization of variable upper bound flow models. In particular, we establish some relations between facets of single- and multi- commodity models. We then introduce a new family of inequalities, which generalizes traditional flow cover inequalities to the multi-commodity context. We present encouraging numerical results. We also consider the directed

The Northwestern Atlantic Moroccan margin, a conjugate of the New Scotland margin, is one of the oldest passive margin of the world. Continental break up occurred at early Liassic time and the deep margin is characterized by a large salt basin. A good knowledge of this basin is of major interest to improve the initial reconstruction between Africa, North America and Iberia (Eurasia). It is also a good opportunity to study a mature passive margin and model its structure and evolution.Moreover, there is a need to assess the geological hazards linked to the neotectonic activity within the Africa-Eurasia plate boundary. These topics have been adressed during the SISMAR cruise carried out from April 9th to May 4th 2001.During this cruise, 3667 km of multichannel seismic reflection (360 channels, 4500 m long streamer, 4800 ci array of air guns) were recorded together with refraction records by means of 48 OBH/OBS drops. Simultaneously, some of the marine profiles have been extended onshore with 16 portable seismic land stations. We present the initial results of this study. Off El Jadida, the Moho and structures within the thinned continental crust are well imaged on both the reflection and refraction records. In the northern area, off Casablanca, we follow the deepening of the moroccan margin beneath the up to 9 sec (twtt) allochtonous series forming a prism at the front the Rif-Betic chain. Sismar cruise has been also the opportunity to record long seismic profiles making the junction between the Portuguese margin and the Moroccan one, and crossing the Iberian-African plate boundary. This allows to observe the continuity of the sedimentary sequence after the end of the large inter-plate motion in Early Cretaceous.

Jean Batiste von Helmont (1577-1644) described a salt that "never occurs outside man's body". The substance was further characterized by Hermann Boerhaave from Leiden (1688-1738) in Elementa Chemiae where he described the whole procedure for isolating it from urine of healthy persons. The French scientists Fourcroy and Vauquelin, in 1808, named it "ure" whereas Jean-Etienne Brard from Montpellier established its chemical composition in 1817. The synthesis of urea was accomplished by Friedrich Whler (the first organic substance to be synthesized). Finally in 1851 Friedrich Th. von Frerichs introduced the term "Uraemia".

Magnetized cosmological perturbations in the post-recombination era

NASA Astrophysics Data System (ADS)

Vasileiou, Hera; Tsagas, Christos G.

2016-01-01

We study inhomogeneous magnetized cosmologies through the post-recombination era in the framework of Newtonian gravity and the ideal-magnetohydrodynamic limit. The non-linear kinematic and dynamic equations are derived and linearized around the Newtonian counterpart of the Einstein-de Sitter universe. This allows for a direct comparison with the earlier relativistic treatments of the issue. Focusing on the evolution of linear density perturbations, we provide new analytic solutions which include the effects of the magnetic pressure as well as those of the field's tension. We confirm that the pressure of field inhibits the growth of density distortions and can induce a purely magnetic Jeans length. On scales larger than the aforementioned characteristic length the inhomogeneities grow, though slower than in non-magnetized universes. Wavelengths smaller than the magnetic Jeans length typically oscillate with decreasing amplitude. We also identify a narrow range of scales, just below the Jeans length, where the perturbations exhibit a slower power-law decay. In all cases, the effect of the field is proportional to its strength and increases as we move to progressively smaller lengths.

Hereditary tyrosinemia type I: strong association with haplotype 6 in French Canadians permits simple carrier detection and prenatal diagnosis.

Demers, S. I.; Phaneuf, D.; Tanguay, R. M.

1994-01-01

Hereditary tyrosinemia type 1 (HT1), a severe inborn error of tyrosine catabolism, is caused by deficiency of the terminal enzyme, fumarylacetoacetate hydrolase (FAH). The highest reported frequency of HT1 is in the French Canadian population, especially in the Saguenay-Lac-St-Jean region. Using human FAH cDNA probes, we have identified 10 haplotypes with TaqI, KpnI, RsaI, BglII, and MspI RFLPs in 118 normal chromosomes from the French Canadian population. Interestingly, in 29 HT1 children, a prevalent haplotype, haplotype 6, was found to be strongly associated with the disease, at a frequency of 90% of alleles, as compared with approximately 18% in 35 control individuals. This increased to 96% in the 24 patients originating from Saguenay-Lac-St-Jean. These results suggest that one or only a few prevailing mutations are responsible for most of the HT1 cases in Saguenay-Lac-St-Jean. Since most patients were found to be homozygous for a specific haplotype in this population, FAH RFLPs have permitted simple carrier detection in nine different informative HT1 families, with a confidence level of 99.9%. Heterozygosity rate values obtained from 52 carriers indicated that approximately 88% of families at risk from Saguenay-Lac-St-Jean are fully or partially informative. Prenatal diagnosis was also achieved in an American family. Analysis of 24 HT1 patients from nine countries gave a frequency of approximately 52% for haplotype 6, suggesting a relatively high association, worldwide, of HT1 with this haplotype.

Jean-Jacques Rousseau's views on adult education

NASA Astrophysics Data System (ADS)

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.

It has been shown that rotation has to play a predominant important role in the formation of many astrophysical objects and the stability of molecular clouds. In this paper the theoretical investigation of the presence of rotation in the magnetized dusty plasma. The general dispersion relation is obtained normal mode analysis technique, and we found the Alfven mode is modified due to the presence of rotation and magnetic field. The graphical presentation shows that rotation and Alfven wave velocity have a stabilizing in the system.

Kubiëna's heritage: worries and hopes about micropedology (Philippe Duchaufour Medal Lecture)

NASA Astrophysics Data System (ADS)

Stoops, Georges

2010-05-01

Kubiëna's book 'Micropedology' (1938) is considered as the start of soil micromorphology, providing the first concepts allowing a systematic description and comparison of soil thin sections as a central tool for understanding soil genesis and for soil classification. The aim of this contribution is to evaluate the impact and the role of micromorphology in different fields of application, and to evaluate its progress as a discipline. The most important application in soil science has always been in the field of soil genesis. This is however affected by the declining interest (and sponsoring) for genesis nowadays. It remains however a must for studies on pedogenesis and weathering. After a strong impulse early in the nineteen sixties, caused by the study of many exotic soils and the development of new soil classification systems (7th Approximation, later Soil Taxonomy) the role of micromorphology declined together with the general interest in soil classification. Its break through as an instrument in classification did not realise. Several causes can be mentioned. On the base of experience gained in the fields of pedogenesis and classification, micromorphology became for geologists and geomorphologists an important instrument in palaeopedology, Quaternary geology and environmental reconstruction. The last two decades an enormous expansion of micromorphological studies has been noticed in the field of archaeology, not only related to ancient soils, but also to many anthropogenic materials. Archaeologists are probably the most intense users of this discipline now. Since the end of the nineteen sixties quantitative micromorphology (micromorphometry) was developed as a response to the demand for numerical data. It expanded mainly since the development of personal computers, but its wider use is essentially restricted to porosity studies related to soil physics. The complete absence of standardisation of methods and parameters hinders however its use and further expansion. Micromorphology proved also to be precious tool in monitoring experiments, both in the laboratory and in the field, often using quantitative data. Changes become visible in thin sections before they can be detected by other methods. Examples are studies on surface crust formation, effects of freezing, gypsum crystallisation and land management. Last years especially archaeologists contributed in these fields. It is also an excellent tool for controlling and interpreting data obtained by other methods. Analysis of literature and abstracts of congresses show that the last two decennia very few contributions were made related to development of micromorphological concepts and techniques. There are several causes for this situation. The bottleneck hindering use and expansion of micromorphology are both technical and theoretical. The main factors are the difficulty to acquire the necessary basic knowledge of optical techniques and micromorphological interpretation, and the difficulty to prepare good thin sections. Solutions are discussed, even as new opportunities for this discipline, at the benefit of different earth sciences.

Hallux valgus, ankle osteoarthrosis and adult acquired flatfoot deformity: a review of three common foot and ankle pathologies and their treatments

2016-01-01

The pathogenesis of hallux valgus deformity is multifactorial. Conservative treatment can alleviate pain but is unable to correct the deformity. Surgical treatment must be adapted to the type and severity of the deformity. Success of surgical treatment ranges from 80% to 95%, and complication rates range from 10% to 30%. Ankle osteoarthrosis most commonly occurs as a consequence of trauma. Ankle arthrodesis and total ankle replacement are the most common surgical treatments of end stage ankle osteoarthrosis. Both types of surgery result in similar clinical improvement at midterm; however, gait analysis has demonstrated the superiority of total ankle replacement over arthrodesis. More recently, conservative surgery (extraarticular alignment osteotomies) around the ankle has gained popularity in treating early- to mid-stage ankle osteoarthrosis. Adult acquired flatfoot deformity is a consequence of posterior tibial tendon dysfunction in 80% of cases. Classification is based upon the function of the tibialis posterior tendon, the reducibility of the deformity, and the condition of the ankle joint. Conservative treatment includes orthotics and eccentric muscle training. Functional surgery is indicated for treatment in the early stages. In case of fixed deformity, corrective and stabilising surgery is performed. Cite this article: Crevoisier X, Assal M, Stanekova K.

Description of the treatment technique of stereotactic lung radiotherapy on Novalis Tx ® and prospective study of the first 100 pulmonary nodules treated at centre Jean-Perrin (France). From October 2012 to December 2015, 100 inoperable pulmonary nodules (62 stage I non-small-cell lung cancer and 38 metastases) of 90 patients with a mean age of 68.2 years (range: 46-89 years) were prospectively treated with dynamic arctherapy on Novalis Tx ® . Mean gross tumour and planning target volumes were respectively 6.9 cm 3 (range: 0.2-31.4 cm 3 ) and 38.7 cm 3 (range: 1.7-131 cm 3 ), which correspond to diameters equal to 2.3cm and 4.2cm. Prescribed doses to the 80% isodose line were 54Gy in three fractions for peripheral non-small-cell lung cancer, 50Gy in five fractions for central non-small-cell lung cancer and 45Gy in three fractions for lung metastases. Clinical and radiological follow-up was done every three months with RECIST criteria for efficacy and NCI-CTCAE v4 scale for toxicity. Median follow-up was 12.5 months. Complete response was observed in 23.8% of cases. Local control rates were 100% and 90.7% respectively at 12 and 24 months, with 96% at 24 months for stage I non-small-cell lung cancer. Overall survival rates of patients with stage I non-small-cell lung cancer were 77.4% and 73.5% at 12 and 24 months (median overall survival was 32 months). Diffusing capacity of the lungs for carbon monoxide corrected for alveolar volume below 40% was significantly associated to a poor prognostic factor on univariate analysis (P=0.00013). At least three deaths were due to an acute respiratory failure, which correspond to about 4.8% of grade 5 radiation pneumonitis. Overall survival rate for metastatic patients were 95.2% and 59.5% respectively at 12 and 24 months (median overall survival was 25 months); 23.3% of grade 2 or less radiation pneumonitis, 7.8% of grade 2 or less radiation dermatitis, 2.2% of asymptomatic ribs fracture and 3.3% of chest pains were observed

Effects of Hurricane Katrina on the forest structure of taxodium distichum swamps of the Gulf Coast, USA

Middleton, B.A.

2009-01-01

Hurricane Katrina pushed mixed Taxodium distichum forests toward a dominance of Taxodium distichum (baldcypress) and Nyssa aquatica (water tupelo) because these species had lower levels of susceptibility to wind damage than other woody species. This study documents the volume of dead versus live material of woody trees and shrubs of T. distichum swamps following Hurricane Katrina along the Gulf Coast of Mississippi and Louisiana. Pearl River Wildlife Management Area near Canton, Mississippi had the highest winds of the study areas, and these forests were located in the northeast quadrant of Hurricane Katrina (sustained wind 151 kph (94 mph)). Jean Lafitte National Historical Park and Preserve south of New Orleans had medium to high winds (sustained winds 111 kph (69 mph) at the New Orleans lakefront). Cat Island National Wildlife Refuge had a lower level of winds and was positioned on the western edge of the storm. The forests at Pearl River and to a lesser extent at Jean Lafitte had the highest amount of structural damage in the study. For Cat Island, Jean Lafitte, and Pearl River, the total volume of dead material (debris) was 50, 80, and 370 m3 ha-1, respectively. The ratio of dead to live volume was 0.010, 0.082, and 0.039, respectively. For both of the dominant species, T. distichum and N. aquatica, the percentage of dead to live volume was less than 1. Subdominant species including Acer rubrum, Liquidambar styraciflua, Quercus lyrata, and Quercus nigra were more damaged by the storm at both Pearl River and Jean Lafitte. Only branches were damaged by Hurricane Katrina at Cat Island. Shrubs such as Morella cerifera, Euonymous sp., and Vaccinium sp. were often killed by the storm, while other species such as Cephalanthus occidentalis, Forestiera acuminata, and Cornus florida were not killed. Despite the fact that Hurricane Katrina was a Category 3 storm and struck Pearl River and Jean Lafitte fairly directly, dominant species of the T. distichum swamps were

critical resuscitation endpoints and drug dose delivery were not improved using AR glasses. However, errors and deviations were significantly reduced in terms of defibrillation doses when compared with the use of the PALS pocket reference cards. In a total of 40 defibrillation attempts, residents not wearing AR glasses used wrong doses in 65% (26/40) of cases, including 21 shock overdoses >100 J, for a cumulative defibrillation dose of 18.7 Joules per kg. These errors were reduced by 53% (21/40, P<.001) and cumulative defibrillation dose by 37% (5.14/14, P=.001) with AR glasses.

Much contemporary anthropology has turned away from exclusive focus on so-called “primitive” tribes in far-away places. The study of urban people has become more prominent, and some researchers have also turned their gaze towards marginalized minorities in their communities. Philippe Bourgois is an example of this. He is well known for studying crack dealers in East Harlem, New York ( In Search of Respect) and homeless heroin addicts in San Francisco (Righteous Dopefiend). Kula Kula was lucky enough to catch him in his office, and had a chat via skype. PMID:25436019

This case-control study was undertaken to determine sociodemographic risk factors for low birth weight in Al-Ain (United Arab Emirates) over a 12-month period in 1992-93. A total of 3485 live births occurred of which 293 (8.4%) were low birth weight. The risk factors considered were mother's occupation, house conditions, place of residence (urban or rural), maternal smoking habits, antenatal care, availability of help in the home, maternal BMI and educational status. Multiple logistic regression analysis showed that mother's occupation, maternal smoking, antenatal care, and lack of help in the home were associated with increased risk of low birth weight.

Descartes, Cardiac Heat, and Alchemy.

PubMed

Heitsch, Dorothea

2016-11-01

René Descartes (1596-1650) insisted on a heat and light theory to explain cardiac movement, and used concepts such as distillation of the vital spirits, fermentation in the digestive process, and fermentation in the circulation of the blood. I argue that his theory of the body as a heat-exchange system was based on alchemical and natural philosophical notions of fire and light expounded by precursors and contemporaries who included Jean D'Espagnet, Jean Fernel, Jan Baptist van Helmont, and Andreas Libavius. Descartes endeavoured to mechanise their approaches, creating a theory in which fire and heat, a legacy from thermal explanations of physiology, were transformed into alchemical fire, and then into mechanistic or physicalist heat.

In his paper Les épistémologies constructivistes: Un nouveau commencement (Sciences de la Société, n°40, 1997), Jean-Louis Le Moigne poses the question: "Le rêve d'une connaissance autoréférentielle se fondant sur elle-même, est sans doute fascinant … Mais est-il scientifiquement raisonnable?". Building on the work of Jean Piaget, I shall try to show through a developmental analysis of elementary, scientifically relevant concepts, such as `change', `object permanence', `space', and `time', that the notion of the thinking subject's construction of knowledge constitutes a more reasonable foundation for science than the traditional belief in the representation of objective reality.

Sub-structure formation in starless cores

NASA Astrophysics Data System (ADS)

Toci, C.; Galli, D.; Verdini, A.; Del Zanna, L.; Landi, S.

2018-02-01

Motivated by recent observational searches of sub-structure in starless molecular cloud cores, we investigate the evolution of density perturbations on scales smaller than the Jeans length embedded in contracting isothermal clouds, adopting the same formalism developed for the expanding Universe and the solar wind. We find that initially small amplitude, Jeans-stable perturbations (propagating as sound waves in the absence of a magnetic field) are amplified adiabatically during the contraction, approximately conserving the wave action density, until they either become non-linear and steepen into shocks at a time tnl, or become gravitationally unstable when the Jeans length decreases below the scale of the perturbations at a time tgr. We evaluate analytically the time tnl at which the perturbations enter the non-linear stage using a Burgers' equation approach, and we verify numerically that this time marks the beginning of the phase of rapid dissipation of the kinetic energy of the perturbations. We then show that for typical values of the rms Mach number in molecular cloud cores, tnl is smaller than tgr, and therefore density perturbations likely dissipate before becoming gravitational unstable. Solenoidal modes grow at a faster rate than compressible modes, and may eventually promote fragmentation through the formation of vortical structures.

Having now worked in soil science and climate change for over 20 years, I find myself giving one of the "old man / old woman" lectures at the EGU2017. You probably get picked to do this when your peers think that you are about to die soon, so I had better make the most of my time left! We are very fortunate to have a career in science, and to belong to the soils, and the wider, biogeosciences communities. If ever you get fed up with your teaching load, with your experiment that won't work, your model that you can't get running, or your paper that reviewers do not realise for the gem that you know it is, remember that we could be doing a 9 to 5 job, stuck in an office, with no opportunities to meet, talk and have fun with others from around the world with whom we share the same passion. I hope you enjoy your research careers and the time you spend with your work friends as much as I have. In this presentation I will reflect on how much I have learned about soils, climate, and the politics of how things get done over the past 20 years, and I will pick out some changes in our understanding of soils, and their role in the world as I go. I will draw on examples not only from my own work, but those of others, and will reflect on the some of the fun I have had while doing this "job".

A computationally tractable version of the collective model

NASA Astrophysics Data System (ADS)

Rowe, D. J.

2004-05-01

A computationally tractable version of the Bohr-Mottelson collective model is presented which makes it possible to diagonalize realistic collective models and obtain convergent results in relatively small appropriately chosen subspaces of the collective model Hilbert space. Special features of the proposed model are that it makes use of the beta wave functions given analytically by the softened-beta version of the Wilets-Jean model, proposed by Elliott et al., and a simple algorithm for computing SO(5)⊃SO(3) spherical harmonics. The latter has much in common with the methods of Chacon, Moshinsky, and Sharp but is conceptually and computationally simpler. Results are presented for collective models ranging from the spherical vibrator to the Wilets-Jean and axially symmetric rotor-vibrator models.

Effect of rotation on gravitational instability of optically thick magnetized quantum plasma in the presence of radiation

NASA Astrophysics Data System (ADS)

Kumar, A.; Pensia, R. K.

2018-05-01

This paper deals with the effect of rotation on the gravitational instability of optically thick magnetized quantum plasma in the presence of radiation. By using linearized perturbation equations of the problem, general dispersion relation is obtained which is reduced for longitudinal and transverse modes of propagation. For each mode, the problem is analyzed for two cases, when the direction of axis of rotation is parallel or perpendicular to the direction of magnetic field. Rotation parameter is found to modify the Jeans criterion of instability and expression for Jeans wavelength for transverse mode, when the axis of rotation is along the direction of magnetic field and it has stabilizing effect on the system. Magnetic field, radiation pressure and quantum correction also found to have stabilizing effect.

Feature-based and object-based attention orientation during short-term memory maintenance.

Top-down attention biases the short-term memory (STM) processing at multiple stages. Orienting attention during the maintenance period of STM by a retrospective cue (retro-cue) strengthens the representation of the cued item and improves the subsequent STM performance. In a recent article, Backer et al. (Backer KC, Binns MA, Alain C. J Neurosci 35: 1307-1318, 2015) extended these findings from the visual to the auditory domain and combined electroencephalography to dissociate neural mechanisms underlying feature-based and object-based attention orientation. Both event-related potentials and neural oscillations explained the behavioral benefits of retro-cues and favored the theory that feature-based and object-based attention orientation were independent.

Guyon Canal: The Evolution of Clinical Anatomy

PubMed Central

Maroukis, Brianna L.; Ogawa, Takeshi; Rehim, Shady A.; Chung, Kevin C.

2016-01-01

The eponym “Guyon canal” refers to the ulnar tunnel at the wrist that was named after the French surgeon Jean Casimir Félix Guyon who first described this space in 1861. After Guyon’s discovery, clinicians have focused their interest on symptoms caused by compression of structures occupying this canal (later named ulnar tunnel syndrome, or Guyon syndrome). However disagreement and confusion persisted over the correct anatomical boundaries and terminology used to describe the ulnar tunnel. Through anatomical investigation and evolving clinical case studies, the current understanding of the anatomy of the ulnar tunnel was established. This article examines the evolution of the anatomical description of the ulnar tunnel and its relevant clinical associations, and casts light on the life and contributions of Jean Casimir Félix Guyon.

A novel JEAnS analysis of the Fornax dwarf using evolutionary algorithms: mass follows light with signs of an off-centre merger

Dwarf galaxies, among the most dark matter dominated structures of our Universe, are excellent test-beds for dark matter theories. Unfortunately, mass modelling of these systems suffers from the well-documented mass-velocity anisotropy degeneracy. For the case of spherically symmetric systems, we describe a method for non-parametric modelling of the radial and tangential velocity moments. The method is a numerical velocity anisotropy 'inversion', with parametric mass models, where the radial velocity dispersion profile, σrr2, is modelled as a B-spline, and the optimization is a three-step process that consists of (I) an evolutionary modelling to determine the mass model form and the best B-spline basis to represent σrr2; (II) an optimization of the smoothing parameters and (III) a Markov chain Monte Carlo analysis to determine the physical parameters. The mass-anisotropy degeneracy is reduced into mass model inference, irrespective of kinematics. We test our method using synthetic data. Our algorithm constructs the best kinematic profile and discriminates between competing dark matter models. We apply our method to the Fornax dwarf spheroidal galaxy. Using a King brightness profile and testing various dark matter mass models, our model inference favours a simple mass-follows-light system. We find that the anisotropy profile of Fornax is tangential (β(r) < 0) and we estimate a total mass of M_{tot} = 1.613^{+0.050}_{-0.075} × 10^8 M_{⊙}, and a mass-to-light ratio of Υ_V = 8.93 ^{+0.32}_{-0.47} (M_{⊙}/L_{⊙}). The algorithm we present is a robust and computationally inexpensive method for non-parametric modelling of spherical clusters independent of the mass-anisotropy degeneracy.

Ph.-N. Pia is known as a philanathropist. In 1770, this apothecary is elected at the board of the city of Paris. Then, he wishes to create a first-aid service to rescue drowned people. In wooden boxes, he gathers together the drugs and devices used at that time, as a fumigating machine to inject tobacco smoke into the intestine, bottles of spirit of camphor, ammonia, a long shirt of wool, wood canulas and flexible pipes made of thin sheep leather. In each of the fiveteen guard houses standing along the river, are deposited a box and a stretcher. As far as Pia is at the head of the military police, he is especially innovating when he decids to train the guards to apply the drugs and the resuscitation processes. With such a regulated way of functioning associated to medical education and granting of awards, within fiveteen years hundreds of people are rescued and resuscitated. Yearly, he publishes the results obtained in Paris and in several places in France, with comments on the situation in the Netherlands, Germany and Britain. In 1780, the king nominates him in the royal order of Saint-Michel. The Révolution supresses the Etablissement en faveur des noyés, and Pia died in 1799 as completely forgotten. In Paris, the first-aid services come back to their former efficiency around 1835, when Marc proposes a special medical training to the fire-men and the military police to form first-aid groups. In this field, the pionneering work of Pia is still of great value and can abe kept in mind as a worldwide reference.

2003-01-01

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

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

Magnetic Fields in Population III Star Formation

Turk, Matthew J.; Oishi, Jeffrey S.; Abel, Tom

2012-02-22

We study the buildup of magnetic fields during the formation of Population III star-forming regions, by conducting cosmological simulations from realistic initial conditions and varying the Jeans resolution. To investigate this in detail, we start simulations from identical initial conditions, mandating 16, 32 and 64 zones per Jeans length, and studied the variation in their magnetic field amplification. We find that, while compression results in some amplification, turbulent velocity fluctuations driven by the collapse can further amplify an initially weak seed field via dynamo action, provided there is sufficient numerical resolution to capture vortical motions (we find this requirement tomore » be 64 zones per Jeans length, slightly larger than, but consistent with previous work run with more idealized collapse scenarios). We explore saturation of amplification of the magnetic field, which could potentially become dynamically important in subsequent, fully-resolved calculations. We have also identified a relatively surprising phenomena that is purely hydrodynamic: the higher-resolved simulations possess substantially different characteristics, including higher infall-velocity, increased temperatures inside 1000 AU, and decreased molecular hydrogen content in the innermost region. Furthermore, we find that disk formation is suppressed in higher-resolution calculations, at least at the times that we can follow the calculation. We discuss the effect this may have on the buildup of disks over the accretion history of the first clump to form as well as the potential for gravitational instabilities to develop and induce fragmentation.« less

"Pulse pair technique in high resolution NMR" a reprint of the historical 1971 lecture notes on two-dimensional spectroscopy.

PubMed

Jeener, Jean; Alewaeters, Gerrit

2016-05-01

The review articles published in "Progress in NMR Spectroscopy" are usually invited treatments of topics of current interest, but occasionally the Editorial Board may take an initiative to publish important historical material that is not widely available. The present article represents just such a case. Jean Jeener gave a lecture in 1971 at a summer school in Basko Polje, in what was then called Yugoslavia. As is now widely known, Jean Jeener laid down the foundations in that lecture of two - and higher - dimensional NMR spectroscopy by proposing the homonuclear COSY experiment. Jeener realized that the new proposal would open the door towards protein NMR and molecular structure determinations, but he felt that useful versions of such experiments could not be achieved with the NMR, computer and electronics technology available at that time, so that copies of the lecture notes were circulated (the Basko Polje lecture notes by J. Jeener and G. Alewaeters), but no formal publication followed. Fortunately, Ernst, Freeman, Griffin, and many others were more far-sighted and optimistic. An early useful extension was Ernst's proposal to replace the original projection/reconstruction technique of MRI by the widely adopted Fourier transform method inspired by the Basko Polje lecture. Later, the pulse method spread over many fields of spectroscopy as soon as the required technology became available. Jean Jeener, Emeritus professor, Université Libre de Bruxelles.

Quantitative assessment of key parameters in qualitative vulnerability methods applied in karst systems based on an integrated numerical modelling approach

NASA Astrophysics Data System (ADS)

Doummar, Joanna; Kassem, Assaad

2017-04-01

In the framework of a three-year PEER (USAID/NSF) funded project, flow in a Karst system in Lebanon (Assal) dominated by snow and semi arid conditions was simulated and successfully calibrated using an integrated numerical model (MIKE-She 2016) based on high resolution input data and detailed catchment characterization. Point source infiltration and fast flow pathways were simulated by a bypass function and a high conductive lens respectively. The approach consisted of identifying all the factors used in qualitative vulnerability methods (COP, EPIK, PI, DRASTIC, GOD) applied in karst systems and to assess their influence on recharge signals in the different hydrological karst compartments (Atmosphere, Unsaturated zone and Saturated zone) based on the integrated numerical model. These parameters are usually attributed different weights according to their estimated impact on Groundwater vulnerability. The aim of this work is to quantify the importance of each of these parameters and outline parameters that are not accounted for in standard methods, but that might play a role in the vulnerability of a system. The spatial distribution of the detailed evapotranspiration, infiltration, and recharge signals from atmosphere to unsaturated zone to saturated zone was compared and contrasted among different surface settings and under varying flow conditions (e.g., in varying slopes, land cover, precipitation intensity, and soil properties as well point source infiltration). Furthermore a sensitivity analysis of individual or coupled major parameters allows quantifying their impact on recharge and indirectly on vulnerability. The preliminary analysis yields a new methodology that accounts for most of the factors influencing vulnerability while refining the weights attributed to each one of them, based on a quantitative approach.

Cozby, Dimitri

2005-08-01

Placing the notion of sin in the context of a meontic account of evil, and emphasizing the effect of sin on the sinner himself, this commentary exposes the insufficiency of restricting oneself to human efforts at atonement, and of thus underemphasizing the role of Christ. Collange's claim that the teaching of "predestination" is rooted in Paul and that the doctrine of merits and indulgences is rooted in Augustine is criticized, and Luther's "forensic" understanding is linked with Augustine, rather than with Paul. Collange's reduction of the concern for holiness to respect and trust is contrasted with holiness's essential context of loving unification with God. The commentary closes by exposing the unsatisfactory scantiness of Collange's treatment of cloning, health-care economy, and of the evils of life.

Mass Extinctions of Pangea (Jean Baptiste Lamarck Medal Lecture)

NASA Astrophysics Data System (ADS)

Wignall, Paul B.

2017-04-01

The 80 million years of Earth history from middle of the Permian to the early Jurassic were some of the worst life ever experienced. The interval includes two mass extinctions that bracket the Triassic period and several lesser crises. It was to be nearly another 120 million years before another major crisis was to strike (this time it was the famous one that removed the dinosaurs). So what was so bad about the 80 million years and why was it so good afterwards? My talk will try to provide at least some of the answers. There are plenty of clues. Notably, the interval coincides with the presence of the Pangea supercontinent and all the extinctions coincided with the eruption of large igneous provinces (LIPs). Indeed, every LIP of this interval coincides with an extinction crisis, a perfect correlation that completely breaks down afterwards. However, getting from correlation to causation is far from straight forward. There are many unknowns - how much gas was released by the volcanism, how quickly and what type of gases were they? These are all questions under investigation. Most of the extinctions of Pangean time coincide with rapid global warming and extensive marine anoxia suggesting that greenhouse gas emissions linked to volcanism were an important extinction driver. For the most severe crises (Permo-Triassic and end-Triassic) losses occurred throughout the food chain all the way down to the primary producers of the oceans and across all habitats including terrestrial ecosystems. At the other end of the spectrum of disaster, the lesser extinctions (Toarcian, Smithian/Spathian) only affected marine invertebrates. The full panoply of catastrophe was played out during the Permo-Triassic mass extinction and has received the most attention. The record in South China shows that there were two phases of extinction. These straddle the boundary and show selective losses initially for shallow-water organisms that were susceptible to high temperatures and then for deeper-water dwellers that succumbed to expanding deep-water anoxia. The contemporary plant losses show a similar duration for extinction losses ( 60 kyr) but the ultimate cause of these extinctions is less clear. It is unlikely to have been directly attributable to greenhouse gases because warm and wet conditions on land are a good thing. A greenhouse is a good place for plants after all. Ozone destruction by halogen emissions followed by intense UV-B radiation is a more promising extinction agent. A key factor in the extinction vulnerability of Pangean life may lie in the subdued nature of carbon cycling in a supercontinent configuration. Feedback mechanisms such as enhanced silicate weathering in warmer, more humid conditions would be less effective because of the vast arid interiors. The burial of carbon in shelf seas would also be minimal because the area of shallow waters around the periphery of the supercontinent was at a Phanerozoic minimum. Once initiated, warmer temperatures would have led to increased rate of organic remineralisation. This may have been responsible the absence of terrestrial organic carbon burial during the most severe crises, further decreasing the ability to drawdown atmospheric carbon. This combination of causes would have produced a planet that was only weakly responsive to sudden influxes of greenhouse gases into the atmosphere. It was a bad time to endure LIP eruptions.

The Attraction of Gravity (Jean Dominique Cassini Medal Lecture)

NASA Astrophysics Data System (ADS)

Iess, Luciano

2017-04-01

The motion of planetary bodies, their interior structure, their shape, and ultimately their landscape, are all determined, more or less directly, by gravity. It is therefore not surprising that by measuring the orbital motion and the gravity field of planets and satellites we have been able to gather crucial information on the interior structure and evolution of those bodies, and at the same time to put the laws of gravity to the test. Planetary geodesy is now a fully developed discipline that uses methods and observable quantities adopted also in other fields, such as space navigation and telecommunications. Thanks to this winning synergy between science and engineering, we can now measure spacecraft velocities to 10-6 m/s and accelerations to 10-9 m/s2 over time scales as short as 1000 s, everywhere in the solar system. The past ten years have seen outstanding results in the scientific exploration of the deep space, with gravity investigations contributing to the success of many missions. Thanks to gravity measurements, MESSENGER was able to unveil the main features of Mercury's interior structure. GRAIL, the first planetary mission entirely devoted to gravity, recovered the structure of the lunar gravity anomalies to a spatial resolution and accuracy unmatched even for the Earth. The discovery and characterization of habitable environments in the Saturnian system, on Enceladus and Titan, were possible also by the radio science investigations of the mission Cassini. Thanks to a carefully designed orbit, with a pericenter just 3000 km above the cloud level, the spacecraft Juno is now carrying out precise gravity measurements at Jupiter to unveil the interior structure of the planet and the depth of its winds. With Cassini providing similar information at Saturn in the Grand Finale orbits, just before the final plunge into the planet, we will soon be able to reveal how similar or different the two gas giants are. But the interior structure of many planetary bodies remains elusive, and much remains to be explored. New missions and new tools are needed. In the next five years the planetary community will see the launch of BepiColombo and JUICE, two spacecraft equipped with a powerful suite of instruments devoted to the tomography of Mercury and Ganymede. Innovative instrumentation and probes are being conceived and designed. The Cassini Medal Lecture will review the past successes and future trends of planetary geodesy and radio science, from the peculiar perspective of someone whose attraction for gravity kept him at the ill-defined boundary between science and engineering, measuring angles, distances and velocities in the solar system.

Did Jean François Barbe Anticipate Charles Darwin?

Drouin, Anne-Sophie; Drouin, Emmanuel; Pereon, Yann

The publication of Charles Darwin's On the Origin of Species in 1859 is widely suppose to have initiated a revolution in science. In 1837, he broke with dogmatic fixism and argued that the adaptation of populations to their local environment was the cause of transmutation. Some contributors helped him start his reasoning: he indeed expressed his indebtedness to Samuel Rowley for having called his attention to Charles Wells' notions of natural selection. Darwin was certainly not the first to suggest the idea of evolution as an alternative to the creation of species by God. We report on a medical thesis published in 1837 being concluded by an unexpected and important statement related to the appearance of mammals on Earth. It remained unknown but it constitutes a link between the transformative thought of Lamarck and Geoffroy Saint Hilaire, and Darwin's work.

In homage to J.D. Martinet, the author, who was his collaborator for more than 25 years, surveys his phlebological work, so diverse and so multiple that it embraces all subjects of the venous pathology of the lower limbs. He cites 3 representative examples on different levels: the information and practical conclusions provided by phlebological investigations, especially retrograde; the classification of phlebitis migrans according to its course; the various problems presented by the surgery of varicose veins. Finally he emphasizes Martinet's qualities of loyalty and intellectual honesty, as well as his role as creator and director of a team (Broca, and later Epee de Bois).

Relativistic magnetised perturbations: magnetic pressure versus magnetic tension

NASA Astrophysics Data System (ADS)

Tseneklidou, Dimitra; Tsagas, Christos G.; Barrow, John D.

2018-06-01

We study the linear evolution of magnetised cosmological perturbations in the post-recombination epoch. Using full general relativity and adopting the ideal magnetohydrodynamic approximation, we refine and extend the previous treatments. More specifically, this is the first relativistic study that accounts for the effects of the magnetic tension, in addition to those of the field’s pressure. Our solutions show that on sufficiently large scales, larger than the (purely magnetic) Jeans length, the perturbations evolve essentially unaffected by the magnetic presence. The magnetic pressure dominates on small scales, where it forces the perturbations to oscillate and decay. Close to the Jeans length, however, the field’s tension takes over and leads to a weak growth of the inhomogeneities. These solutions clearly demonstrate the opposing action of the aforementioned two magnetic agents, namely of the field’s pressure and tension, on the linear evolution of cosmological density perturbations.

A MAGNETIC RIBBON MODEL FOR STAR-FORMING FILAMENTS

We develop a magnetic ribbon model for molecular cloud filaments. These result from turbulent compression in a molecular cloud in which the background magnetic field sets a preferred direction. We argue that this is a natural model for filaments and is based on the interplay between turbulence, strong magnetic fields, and gravitationally driven ambipolar diffusion, rather than pure gravity and thermal pressure. An analytic model for the formation of magnetic ribbons that is based on numerical simulations is used to derive a lateral width of a magnetic ribbon. This differs from the thickness along the magnetic field direction, which ismore » essentially the Jeans scale. We use our model to calculate a synthetic observed relation between apparent width in projection versus observed column density. The relationship is relatively flat, similar to observations, and unlike the simple expectation based on a Jeans length argument.« less

Dinosaur Impressions

NASA Astrophysics Data System (ADS)

Taquet, Philippe

1998-09-01

Perhaps you are a paleontologist or have always wondered what it is like to be one. Or you are fascinated by fossils and like to read about the origins and natural history of dinosaurs. Or maybe you are an avid traveler and reader of travelogues. If you are any of these things, then this book is for you. Originally published in 1994 in French, Dinosaur Impressions is the engaging account of thirty years of travel and paleontological exploration by Philippe Taquet, one of the world's most noted paleontologists. Dr. Taquet takes the reader on a surprisingly far-flung tour ranging from the Provence countryside to the Niger desert, from the Brazilian bush to the Mongolian Steppes, and from the Laos jungle to the Moroccan mountains in search of dinosaur bones and what they have to tell us about a vanished world. With wry humor and lively anecdotes, Dr. Taquet retraces the history of paleontological research, along the way discussing the latest theories of dinosaur existence and extinction. Elegantly translated by Kevin Padian, Dinosaur Impressions provides a unique, thoughtful perspective not often encountered in American- and English-language works. This insightful, first-hand account of an exceptional career is also a travelogue par excellence that will enthrall enthusiasts and general readers alike. Philippe Taquet is the Director of the National Museum of Natural History in Paris and is a member of the French Academy of Sciences. Kevin Padian is a professor in the Department of Integrative Biology and Curator of the Museum of Paleontology at the University of California, Berkeley. He is also the editor of The Beginning of the Age of Dinosaurs (Cambridge, 1986) and The Encyclopedia of Dinosaurs (1997).

Fish debris record the hydrothermal activity in the Atlantis II deep sediments (Red Sea)

1988-01-01

The REE and U, Th, Zr, Hf, Sc have been analyzed in samples from Atlantis II and Shaban/Jean Charcot Deeps in the Red Sea. The high Zr/Hf ratio in some sediments indicates the presence of fish debris or of finely crystallized apatite. The positive ..sigma..REE vs P/sub 2/O/sub 5/ and ..sigma..REE vs Zr/Hf correlations show that fish debris and finely crystallized apatite are the main REE sink in Atlantis II Deep sediments as in other marine environments. The hydrothermal sediments and the fish debris concentrates have similar REE patterns, characterized by a LREE enrichment and a large positive Eu anomaly.more » This REE pattern is also observed in E.P.R. hydrothermal solutions. Fish debris from marine environments acquire their REE content and signature mostly from sea water during early diagenesis. The hydrothermal REE signature of Atlantis II Deep fish debris indicate that they probably record the REE signature of their hydrothermal sedimentation and diagenetic environment. The different REE signatures of the Shaban/Jean Charcot and Atlantis II Deep hydrothermal sediments suggest a sea water-dominated brine in the Shaban/Jean Charcot Deep as opposed to the predominantly hydrothermal brine in Atlantis II Deep. Atlantis II Deep fish debris are also characterized by their high U but low Th contents. Their low Th contents probably reflect the low Th content of the various possible sources (sea water, brine, sediments). Their U contents are probably controlled by the redox conditions of sedimentation.« less

[Transsexualism : an obsolete nosological category].

Alessandrin, Arnaud

Transsexualism is a recent medical invention. In France, the diagnosis and clinical assessment of transsexualism are carried out jointly by lawyers, doctors and psychiatrists. However, recent quantitative and qualitative studies have shown that current uses of the concept of "transsexualism" no longer meet the demands of all trans people. Only a minority of trans people undergo a public protocol of transsexualization for the transition process. This finding is supported by evidence from a quantitative survey conducted by Alain Giami, and is apparent in the life stories of people who avoid using the "transsexual" label and criticize the clinical process for mistreating people. The purpose of this paper is to analyze the mechanisms of the subjective depsychiatrization and depathologization of trans identities and to examine current conceptions of trans "becomings".
