    2010-01-01

    It was with deep sadness that we learnt that Jean Roche had died. Jean was one of those quietly efficient and conscientious pillars of our community who beaver away unobtrusively for decades and make such a contribution to building CERN. An expert in thermal engineering, he left his mark on many buildings on the Meyrin and Prévessin sites. At the time of the LEP project at the beginning of the 1980s he was in charge of defining the principles of the ventilation systems for the new accelerator. Through his design studies and the calls for tenders that he launched, he developed these high-performance state-of-the-art installations which not only made LEP’s successes possible but also served as benchmarks for the fundamental principles underpinning the design of the LHC ventilation system. Jean always liked to surround himself with young people and during the years of his stewardship the design office was a splendid training ground. Despite his responsibilities, Jean was always keen t...

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

    Full Text Available Jean Rouch explored the fortuitous, as well as dreams and theimagination of his actors in creating his films. These features identify him as one of the heirs of Surrealism. This article analyzes how his films tackle the ideas of the movement that agitated France in the 1920s. Thus, it presents the discourse constructed by Rouche’s analysts on the relations between his work and Surrealism. It then proceeds to analyse the films La Punition, 1960, and Gare du Nord, 1965. This article proposes that Rouch is not guided by the most famous surrealist images denaturalizing daily life. On the contrary, he will create another kind of surrealist images.

    A transcript is presented of a speech on the history of the development of hydrogenation of coal and tar. Apparently the talk had been accompanied by the showing of photographic slides, but none of the pictures were included with the report. In giving the history, Dr. Pier mentioned the dependence of much of the development of hydrogenation upon previous development in the related areas of ammonia and methanol syntheses, but he also pointed out several ways in which equipment appropriate for hydrogenation differed considerably from that used for ammonia and methanol. Dr. Pier discussed the difficulties encountered with residue processing, design of the reaction ovens, manufacture of ovens and preheaters, heating of reaction mixtures, development of steels, and development of compressor pumps. He described in some detail his own involvement in the development of the process. In addition, he discussed the development of methods of testing gasolines and other fuels. Also he listed some important byproducts of hydrogenation, such as phenols and polycyclic aromatics, and he discussed the formation of iso-octane fuel from the butanes arising from hydrogenation. In connection with several kinds of equipment used in hydrogenation (whose pictures were being shown), Dr. Pier gave some of the design and operating data.

    The idea of a "Hydrogen Economy" is that carbon containing fuels should be replaced by hydrogen, thus eliminating air pollution and growth of CO₂ in the atmosphere. However, storage of a gas, its transport and reconversion to electricity doubles the cost of H₂ from the electrolyzer. Methanol made with CO₂ from the atmosphere is a zero carbon fuel created from inexhaustible components from the atmosphere. Extensive work on the splitting of water by bacteria shows that if wastes are used as the origin of feed for certain bacteria, the cost for hydrogen becomes lower than any yet known. The first creation of hydrogen and electricity from light was carried out in 1976 by Ohashi et al. at Flinders University in Australia. Improvements in knowledge of the structure of the semiconductor-solution system used in a solar breakdown of water has led to the discovery of surface states which take part in giving rise to hydrogen (Khan). Photoelectrocatalysis made a ten times increase in the efficiency of the photo production of hydrogen from water. The use of two electrode cells; p and n semiconductors respectively, was first introduced by Uosaki in 1978. Most photoanodes decompose during the photoelectrolysis. To avoid this, it has been necessary to create a transparent shield between the semiconductor and its electronic properties and the solution. In this way, 8.5% at 25 °C and 9.5% at 50 °C has been reached in the photo dissociation of water (GaP and InAs) by Kainthla and Barbara Zeleney in 1989. A large consortium has been funded by the US government at the California Institute of Technology under the direction of Nathan Lewis. The decomposition of water by light is the main aim of this group. Whether light will be the origin of the post fossil fuel supply of energy may be questionable, but the maximum program in this direction is likely to come from Cal. Tech.

  7. Jeans instability in a universe with dissipation

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

    2018-01-01

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

  1. Relationship between the Physical Properties and Hand of Jean Fabric

    2016-09-01

    Full Text Available We investigated the distinctive characteristics of jean fabrics (denim fabrics obtained from jeans and compared the physical properties and the hand. We used 13 kinds of jean fabric from commercial jeans and 26 other fabric types. The physical properties were measured using the Kawabata evaluation system, and the fabric hand was evaluated by 20 subjects using a semantic differential method. To characterise the hand of jean fabrics compared with other fabrics, we used principal component analysis and obtained three principal components. We found that jean fabrics were characterised by the second principal component, which was affected by feelings of thickness and weight. We further characterised the jean fabrics according to ‘softness & smoothness’ and ‘non-fullness’, depending on country of origin and type of manufacturer. The three principal components were analysed using multiple linear regression to characterise the components according to the physical properties. We explained the hand of fabrics including jean fabrics using its association with physical properties.

  14. Jean-Claude Risset's Sud: an analysis

    Directory of Open Access Journals (Sweden)

    Giselle Martins dos Santos Ferreira

    2002-02-01

    Full Text Available This article presents a perceptual analysis of Jean-Claude Risset's Sud. A theoretical stance is adopted that is based on Gregory Bateson’s Theory of Mind (Bateson, 1980, Mind and Nature, which suggests that perception operates as a continuous dialectic between concept and sense-data. A complementarity between intrinsic and extrinsic connotations in electroacoustic music is assumed, and a broad concept of structure is suggested, prompting the notion of meaning as a multi-layered construct that relates musical and worldly experiences. From this perspective, Sud may be perceived as an encounter between human imagination and nature in two of its most powerful symbols: the sea, alluded to through the sounds of the waves, and the forest, alluded to through the sounds of birds and insects. The piece presents an exploration of the essence of these environmental sounds, which are either modified or recreated with different substances. In its appeal to images widespread in a variety of cultures, as well as in its unique use of traditional musical materials, Sud is more than a strongly programmatic and visually evocative piece. §Part of the material presented here was originally published in Ferreira, G. M. d. S. A Perceptual Approach to the Analysis of J. C. Risset's Sud: sound, structure and symbol. 1997. Organised Sound v.2 n.2 pp.97-106. Permission obtained from the Cambridge University Press.

    Jean-Claude Brunet passed away on 27 February 2016.   Brunet joined CERN in 1966 and was one of the key players in the design of the colliders, from the ISR, the first Intersecting Storage Rings, to the LHC, not forgetting the AA, the first Antiproton Accumulator, and LEP. An engineer in the design office, he participated as a precursor to the development and implementation of many elements of the ultra-high vacuum (UHV) systems of these machines. He also played an important role in the design and construction of the LHC cryostats. As a leader, he was always open-minded and much appreciated by the younger generations. His strong energy led him to be a staff representative and one of the pillars of the touring section of the Ski Club. We have lost a creator, a traveller, a sailor, a mountaineer and a great friend. Our thoughts go to his wife, Marie-Claude and his family. His friends and former colleagues

    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.

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

The formation of the imaginary of Cocteau was marked from his childhood by the traumatic death of his father that his mother wanted to compensate overprotecting him. Through the symbology present in his first film we will establish analogies and relationships between the author’s own biography, references to the myth of Orpheus and the interpretation that other artists close to surrealism made of these elements.

    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.

  10. Transcultural nursing: a perspective derived from Jean-Paul Sartre.

    Science.gov (United States)

    Rajan, M F

    1995-09-01

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

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

    Full Text Available In this article I would like to show in which way in the works ofFrench philosopher Jean-Luc Nancy there are links between “community” and“communism”. The latter, for him, has a meaning exceeding the domain of politicsand should be understood as a some kind of pre-existential and quasi-onthologicalcategory. Being-in-common means for philosopher being-with which is expressedby Latin prefix “com” characterizing “communitas” and “communism”. “Com”emphasizes that being is first of all being with other (not only with other peoplebut with every other being including in it animals, plants etc. Furthermore, asNancy said: “communism is togetherness – the Mitsein, the being- with, understood as the belonging to existence of the individuals, which means, in the existential meaning, to their essence”. Therefore, Nancy’s community doesn’t belong to “the logic of myth” since is, in the first place, what he called “the inoperative community”.

    Cristiano Eduardo Wendt

    2012-05-01

    Full Text Available The essay discusses the importance of Jean-Jacques Rousseau for modern pedagogy, by being grounded on his philosophical-pedagogical work Émile or On Education. It seeks to present the meaning of pedagogical enlightenment as well as the concept of natural education, and the two great novelties brought by Rousseau to the educational realm, i.e., the concept of infancy and of education. In this perspective, it analyzes the three main interpretations to which Rousseau’s enlightenment was submitted along history: As an optimist of reason, primitivist and dialectician of reason. Assuming the Genevan’s thought as a defender of a dialectics of reason, the essay seeks to reflect the unfolding which every concept provokes to its project of natural education and how it reflects in the cognitive and moral development of the infants. At last it deals with the presentation of two innovations which Rousseau brings to the realm of education, the first one which deals with the concept of infancy, and the second one which deals with the pedagogical concept as a whole, by considering the phases of biological, cognitive and moral maturing, where each child is encountered.

  8. The Chiasmus of Mourning and Identification in Jean Genet

    2000-06-01

    Full Text Available The theories of psychological identification proposed by Sigmund Freud and Kaja Silverman are explored in relation to Jean Genet's Funeral Rites and his later essay on Rembrandt. Genet can be seen to separate mourning (which for Freud lies at the basis of identification from a process of generalized identification in which his difference from other people dissolves. A narcissistic formation of personality, evident in the symbolism of mirrors in Funeral Rites , gives to this process an added impetus. But the fundamental condition of possibility for such generalized identification is the void it reveals at the center of all personality. This void not only makes possible the different kinds of identification (heteropathic and idiopathic described by Silverman, it also disturbs any clear distinction between them. It is for these reasons that the glamorization of Nazism in Funeral Rites is coextensive with a demystification of its power, and the often brutal eroticism of the book is suffused with an ineradicable dimension of tenderness. Taken further in the essay on Rembrandt, these themes lead to an ambiguous mysticism in which the source of creativity is revealed as inseparable from its ultimate obliteration.

Lettre aux paysans sur la pauvreté et la paix (1938 of the Occcitan writer Jean Giono is not a praise of poverty but the praise of a modest measure, linked to the dramatic situation of that time but generally valid. The Lettre is now a classic. We present it starting from the recipe of a vegetable soup, humble fulcrum of the author’s message meant to announce the reform of the rural world. The topic of the letter has an arrival point with L’homme qui plantait des arbres, written by Giono in 1953 and published in 1980, gaining a success ever renewed; the Italian translation, L’uomo che piantava gli alberi obtained a similar success. There is not mention of the food but its environmental premises perform a protagonist role.

    Full Text Available Jean-Marie Lustiger admired John Paul II and he was devoted to him. They both had similar origin. The Cardinal of Paris often accompanied the pope in his pastoral visits. He perceived John Paul II as the man of Providence. He was convinced that God had prepared him to this role. Jean-Marie Lustiger emphasized the attitudes of John Paul II that attracted the attention and admiration of observers. For instance: pray, holiness, attentive pastor and good relation with young people. Jean-Marie Lustiger as an attentive observer also focused his attention on the pastoral methods of John Paul II. In his utterances he often perceived the following methods: each person was important, defense of person’s dignity, the ability to speak with each man, modern language, importance of the pastoral visits and sui generis spiritual pedagogic. Jean-Marie Lustiger noticed radical change of perspective in preaching and in pastoral action of John Paul II. According to him the pope perceived the challenges of the modern times, evaluated needs of the humanity and gave the appropriate answers. For these he did not choose politics, sociology or even anthropology as a re fl ection but addressed to the hurt human who was redeem by Jesus Christ.

    Rozina, Ch.; Tsintsadze, N. L.; Madiha, M.; Zeba, I.

    2017-05-01

    A kinetic theory of the Jeans instability of a self gravitating dusty plasma has been developed in the presence of nonlinear Landau damping (NLD) term. We demonstrate that NLD alters the growth rate of the gravitational collapse of the gravitating dusty plasma. The dispersion relation of modified Jeans instability is obtained and analyzed for specific conditions. Jeans frequency is compared with the dust acoustic frequency; new definition of Jeans wave length is introduced. The maximum growth rate is obtained for a particular condition as well as the Jeans critical mass is defined. Next to address the heating of plasma through radiation processes, we investigate the nonlinear theory of high frequency electromagnetic waves (EMWs) in a collisionless dusty plasma by using a set of Vlasov-Poisson equations. The effects of the nonlocal nonlinear Landau term (appearing due to the nonlinear interaction of EMWs with gravitating dusty plasma) in the nonlinear Schrödinger equation are examined. It is found that nonlinear Landau damping of EMWs leads to transfer of effective energy to the plasma particles, the corresponding decay rate of EMWs appears to be a function of amplitude of electromagnetic pump waves, and damping can be faster in the presence of large ion number density.

  15. Exploiting natural fracture and fault fairways in the Jean Marie carbonate platform

    Wierzbicki, R.; Todorovic-Maranic, D [EnCana Corp., Calgary, AB (Canada)

    2010-07-01

    The Jean Marie carbonate is an Upper Devonian aged carbonate platform that developed on the western margin of North America. The Jean Marie is an under pressured, low permeability, slightly fractured limestone, and is rarely dolomitic. Dry gas is trapped in a regional stratigraphic trap as the Jean Marie changes laterally up dip into a thin tight mudstone. To minimize damage to the fine pore system in this under-pressured reservoir, the pool has been developed using underbalanced horizontal drilling. Advanced seismic techniques are being utilized to detect porosity zones and high permeability fairways which increase deliverability and recovery of gas from the Jean Marie carbonate. Variable well productivity has been observed in similar facies, as has high productivity in low porosity rock. This presentation reviewed the nature of fractures in the Jean Marie from thin section to the seismic scale and focus on the seismic methods utilized to detect and exploit these high permeability fairways. The paper provided a geological overview of the region and identified previous studies. The paper also reviewed drilling results and production indicators of fracture flow. The controls on fracturing were also discussed. It was concluded that of the 109 wells drilled in the study area, 44 encountered significant permeability enhancements associated with open fractures and leached carbonates. 14 refs., 21 figs.

    This paper presented the exploration and development of the Jean Marie Member, a tight gas-saturated carbonate, located in northeast British Columbia. This large concentrated gas resource is known to have a repeatable exploitation method of underbalanced horizontal wells. EnCana has converted from nitrogen foam to drilling with natural gas. This paper discussed the regional Jean Marie geology, including deposition, facies, reservoir characteristics, and gas volumes-in-place. It also discussed the chronology of the exploration and development of the Jean Marie play from the 1960s to present. Most of the data analysed and presented was from Encana. The paper also summarized the five key drivers influencing the successful exploitation of the Jean Marie, including its dominant land position on quality acreage; highly-connected multi-disciplinary teams; repeatable yet evolving processes; awareness and application of new technologies; and rigorous tracking and discipline. The future development in the Greater Sierra Jean Marie is supported by a large inventory of multi-lateral horizontal wells, executed using the gas factory model. refs., figs., appendices.

    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

  18. On Jewish Being: Notes on Jean Améry

    2017-02-01

    Full Text Available That the question of identity takes on a sense of urgency, one with its own possibilities and impossibilities, the moment that identity is bound up with death, is hardy surprising. What follows are a series of reflections on the question of identity, Jewish identity, raised by Jean Améry’s remarkable text On the Necessity and Impossibility of Being a Jew (Über Zwang und Unmöglichkeit, Jude zu sein. Améry’s text was of course published in the wake of his own experiences as an active member of the resistance, as having been imprisoned in Auschwitz and as the victim of torture. Philosophically, rather than biographically, if there were a point of comparison, then it is to Levinas’s 1947 text Etre juif. Both pose the problem of how the question of Jewish identity, Jewish being, is to be understood in the wake of the Shoah. The meaning of the formulations - Jude zu sein, Jude sein, Etre juif, Jewish being – delimits the question to be addressed. This will be the case even if its point of address, namely what the question stages, is itself far from straightforward. Moreover, while what is demanded within that question is itself philosophically important, it is equally the case that the question of Jewish being is at work within both communities and synagogues across the Jewish world. As a consequence it is as much a philosophical question as it is one that has a structuring effect on how Jewish survival is conceived (and thus equally on what that survival is taken to be. How survival is understood is an issue that continues to exert its force. Who is the subject of survival? What is the subject of survival? Who or what has been subjected to the issue of survival? Survival is both more nuanced and complex than the brute fact of an afterlife. Jewish being as a present question – a question of the present - continues therefore.

    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

    > A generalized hydrodynamic model is used to analyse the growth rate of the Jeans instability of a partially ionized strongly coupled plasma incorporating the effects of rotation and Hall current. The general dispersion relation is determined for the propagation of magnetohydrodynamic waves using the normal mode analysis theory. The general dispersion relation is further discussed in four different combinations of rotation and propagation of the system to signify the importance of rotation and neutral particles on the growth rates and conditions of Jeans instability in hydrodynamic and kinetic regimes. The different types of waves are also described in these cases. The influence of rotation and neutral particles on growth rate of the Jeans instability is analysed numerically and shown graphically. The possible applications of the present work are found in ultracold neutral plasmas, white dwarfs, neutron stars etc.

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

    Science.gov (United States)

    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.

  12. Hydrogen Embrittlement

    Science.gov (United States)

    Woods, Stephen; Lee, Jonathan A.

    2016-01-01

    Hydrogen embrittlement (HE) is a process resulting in a decrease in the fracture toughness or ductility of a metal due to the presence of atomic hydrogen. In addition to pure hydrogen gas as a direct source for the absorption of atomic hydrogen, the damaging effect can manifest itself from other hydrogen-containing gas species such as hydrogen sulfide (H2S), hydrogen chloride (HCl), and hydrogen bromide (HBr) environments. It has been known that H2S environment may result in a much more severe condition of embrittlement than pure hydrogen gas (H2) for certain types of alloys at similar conditions of stress and gas pressure. The reduction of fracture loads can occur at levels well below the yield strength of the material. Hydrogen embrittlement is usually manifest in terms of singular sharp cracks, in contrast to the extensive branching observed for stress corrosion cracking. The initial crack openings and the local deformation associated with crack propagation may be so small that they are difficult to detect except in special nondestructive examinations. Cracks due to HE can grow rapidly with little macroscopic evidence of mechanical deformation in materials that are normally quite ductile. This Technical Memorandum presents a comprehensive review of experimental data for the effects of gaseous Hydrogen Environment Embrittlement (HEE) for several types of metallic materials. Common material screening methods are used to rate the hydrogen degradation of mechanical properties that occur while the material is under an applied stress and exposed to gaseous hydrogen as compared to air or helium, under slow strain rates (SSR) testing. Due to the simplicity and accelerated nature of these tests, the results expressed in terms of HEE index are not intended to necessarily represent true hydrogen service environment for long-term exposure, but rather to provide a practical approach for material screening, which is a useful concept to qualitatively evaluate the severity of

HX-MS monitors isotopic exchange of hydrogen in protein backbone amides and thus serves as a sensitive method for probing protein conformation...... and dynamics along the entire protein backbone. This chapter describes the exchange of backbone amide hydrogen which is highly quenchable as it is strongly dependent on the pH and temperature. The HX rates of backbone amide hydrogen are sensitive and very useful probes of protein conformation......, as they are distributed along the polypeptide backbone and form the fundamental hydrogen-bonding networks of basic secondary structure.

    We analyze the stability of self-gravitating systems which dynamics is investigated using the collisionless Boltzmann equation, and the modified Poisson equation of Eddington-inspired Born-Infield gravity. These equations provide a description of the Jeans paradigm used to determine the critical scale above which such systems collapse. At equilibrium, the systems are described using the time-independent Maxwell-Boltzmann distribution function f{sub 0}(v). Considering small perturbations to this equilibrium state, we obtain a modified dispersion relation, and we find a new characteristic scale length. Our results indicate that the dynamics of self-gravitating astrophysical systems can be fully addressed in the Eddington-inspired Born-Infeld gravity. The latter modifies the Jeans instability in high densities environments, while its effects become negligible in star formation regions. (orig.)

    1942-10-16

    This report mentioned that not very severe demands for purity were made on the hydrogen used in hydrogenation of coal or similar raw materials, because the catalysts were not very sensitive to poisoning. However, the hydrogenation plants tried to remove most impurities anyway by means of oil washes. The report included a table giving the amount of wash oil used up and the amount of hydrogen lost by dissolving into the wash oil used up and the amount of hydrogen lost by dissolving into the wash oil in order to remove 1% of various impurities from 1000 m/sup 3/ of the circulating gas. The amounts of wash oil used up were 1.1 m/sup 3/ for removing 1% nitrogen, 0.3 m/sup 3/ for 1% carbon monoxide, 0.03 m/sup 3/ for 1% methane. The amount of hydrogen lost was 28 m/sup 3/ for 1% nitrogen, 9 m/sup 3/ for 1% methane and ranged from 9 m/sup 3/ to 39 m/sup 3/ for 1% carbon monoxide and 1 m/sup 3/ to 41 m/sup 3/ for carbon dioxide depending on whether the removal was done in liquid phase or vapor phase and with or without reduction of the oxide to methane. Next the report listed and described the major processes used in German hydrogenation plants to produce hydrogen. Most of them produced water gas, which then had its carbon monoxide changed to carbon dioxide, and the carbon oxides washed out with water under pressure and copper hydroxide solution. The methods included the Winkler, Pintsch-Hillebrand, and Schmalfeldt-Wintershall processes, as well as roasting of coke in a rotating generator, splitting of gases formed during hydrogenation, and separation of cokery gas into its components by the Linde process.

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

    It is proved that the «system of things» of Jean Baudrillard points out that the power of advertising is based on the belief in her from a mass consumers.. The root of this belief - the so-called «infantile bestowing function», which creates a sense of mythic human involvement, which is in this context belongs to a social nature.

    Full Text Available The aim of this paper is to examine the role of humour in Théâtre sans animaux. Our approach is to define two forms of humour which play on the effects of incoherence: the unusual and the absurd. We then examine these two forms of humour and the effects which they produce in Jean-Michel Ribes’s text. We show the specificity of the humor of Ribes which articulates the unusual with the absurd.

    2015-01-01

    This volume presents five different methods recently developed to tackle the large scale behavior of highly correlated random systems, such as spin glasses, random polymers, local times and loop soups and random matrices. These methods, presented in a series of lectures delivered within the Jean-Morlet initiative (Spring 2013), play a fundamental role in the current development of probability theory and statistical mechanics. The lectures were: Random Polymers by E. Bolthausen, Spontaneous Replica Symmetry Breaking and Interpolation Methods by F. Guerra, Derrida's Random Energy Models by N. Kistler, Isomorphism Theorems by J. Rosen and Spectral Properties of Wigner Matrices by B. Schlein. This book is the first in a co-edition between the Jean-Morlet Chair at CIRM and the Springer Lecture Notes in Mathematics which aims to collect together courses and lectures on cutting-edge subjects given during the term of the Jean-Morlet Chair, as well as new material produced in its wake.

    A CERN engineer and an accomplished sportsman, Jean-Yves Le Meur (IT Department) has recently published his first book "Faux pas". Meet him and hear about his exceptional life on 23 April 2008 in the Globe. An accident cost him his legs when he was young, and it was sheer force of character and a passion for the mountains that carried Jean-Yves Le Meur, with one artificial leg and crutches to stay upright, to the very summit of the Mont-Blanc. In his book, Jean-Yves, a computer engineer at CERN, recounts with detachment his personal battle to win back his life and make this impossible ascent. "Faux Pas" depicts a series of encounters and people, and recreates the extreme emotions of a man who reconstructed his life and pushed himself beyond his limits. It is a moving personal account, whose message is universal. The question-and-answer session with the author will be preceded by the projection of "4810M, CAHIN-CAHA",...

  14. Deuterium and hydrogen flows in the thermosphere

    Breig, E. L.; Hanson, W. B.

    1991-01-01

    Processes that affect vertical distributions and flows of deuterium and hydrogen between 100 and 500 km in the daytime thermosphere are investigated using a steady state numerical model that includes HD and H2 molecular flows, relevant chemistry, and transport by both molecular and eddy diffusion. The results of calculations indicate that the outward thermospheric fuxes and, hence, the planetary loss rates for D must be large compared to evaporative escape (as is also the case for H), confirming the suggestion of Breig et al. (1987). Results of measurements of H in the mesosphere and lower thermosphere and of H and D in the thermosphere were used to derive upward fluxes through the daytime thermosphere, showing that the upward fluxes exceeded the corresponding Jeans evaporative escape rates by factors of about 5 for H, and greater than 500 for D.

    Full Text Available This essay analyses the self-portraits of Jean-Étienne Liotard (1702-1789. Interpreting these objects through the lens of Maurice-Merleau-Ponty's writings on art and vision, I argue that Liotard's self-portraits can be understood as artistic experiments relating to the fundamental phenomenological problem of seeing and representing the lived-body. In making this argument this essay re-evaluates the art-historical tendency to read Liotard's self-portraits biographically as pictures of his unusual life or as tools of self-promotion.

    Full Text Available This article revisits the ending of Jean-Luc Godard’s Breathless (1960 in an attempt to untangle the complicated relationship between the two main characters, and to claim that they are characters that belong to no identifiable genre. Instead, they come to life as characters at the intersection point of existentialism, creationism, and two radically different genres, film noir and neorealism. In essence, they are characters without a genre, always out of place, and their existential drifting generates a Judas effect—a trope that establishes betrayal and sacrifice as necessary narrative tools and that suspends the classical (cinematic Oedipal cycle.

    Science.gov (United States)

    Fletcher, John

    2007-10-01

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

Jean Luc Nancy has problematized this notion and tried to free it from any trace of what might be a thought or identity politics. The community is not the affirmation of a being of us but the breakdown of any form of essentialism which entails the need to recognize the role of otherness and difference. Hence, linking the community to a finitude that relates to concepts such as death, “clinamen”, transcendence and especially the absence of Oeuvre

    2017-05-01

    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.

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

    Full Text Available After the revocation of the Edict of Nantes in 1685, over 400 Huguenot ministers made their way to the Dutch Republic in search of a new pulpit. They stood a good chance, because the Huguenot exodus resulted in a corresponding demand for French preachers, while Dutch authorities offered financial support. Yet a surplus of ministers also meant fierce competition over positions. The careers of Jean and Isaac Claude show that on this highly competitive market Huguenot ministers succeeded in gaining a position in the Dutch Republic by virtue of their reputation, networks, and religious and political ideas.

    Chauvin, Frédéric; Fischer, Louis-Paul

    2010-01-01

    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.

  20. Influence of polarization force on Jeans Self Gravitational Instability of Strongly Coupled dusty Plasma

    Science.gov (United States)

    Sharma, Prerana

    In the present work, we investigate the influence of dust polarization force on the Jeans instability of self-gravitating strongly coupled dusty fluids. We consider dusty plasma containing strongly correlated negatively charged dust grains and weakly correlated Maxwellian electrons and ions. The formulation of the present work is done using the general hydrodynamic model and it is based on the assumption that dust polarization force is aroused due to the electrostatic interactions between thermal ions and highly negatively charged dust grains. In deriving dispersion relation the plane wave solutions are used on the linearized perturbation equations. The analysis is done by normal mode analysis theory. The dispersion relation is analyzed to obtain Jeans instability criterion of instability. Numerical results are presented to show the effect of polarization parameter and strong correlation effects of dust. The polarization force and strong coupling effects of dust are shown to affect the growth rate of gravitational mode of propagation. The growth rates are further compared in kinetic and hydrodynamic regime of propagation. It is found that the decay in the growth rate is faster in the kinetic mode of propagation in comparison to the hydrodynamic mode. The present investigation is relevant to the collapse of ultra-cold astrophysical objects like inner core of white dwarf and neutron star.

    Full Text Available Jean-Luc Nancy, one of the most influential philosophers of today, is part of a group to some extent antagonistic. Marked by Heidegger's phenomenology, for a certain Hegelianism and the grounds of literary criticism of Maurice Blanchot, Nancy is coming from philosophers like Derrida and Philippe Lacoue-Labarthe. He teaches philosophy at the Faculty of Philosophy, Science of Language and Communication at the University of Strasbourg. Author of several works, his thoughts are evoked by quotations from scholarly works in many different areas. In this study, without attempting to exhaust the subject, we will discuss art, poetry and literature in light of the thought of Nancy, also featuring, when needed, the help of other established names.

  14. Jean-Jacques Rousseau's copy of Albrecht von Haller's Historia stirpium indigenarum Helvetiae inchoata (1768).

    Science.gov (United States)

    Cook, A

    2003-04-01

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

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

    Science.gov (United States)

    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.

  17. Errors from Rayleigh-Jeans approximation in satellite microwave radiometer calibration systems.

    Science.gov (United States)

    Weng, Fuzhong; Zou, Xiaolei

    2013-01-20

    The advanced technology microwave sounder (ATMS) onboard the Suomi National Polar-orbiting Partnership (SNPP) satellite is a total power radiometer and scans across the track within a range of ±52.77° from nadir. It has 22 channels and measures the microwave radiation at either quasi-vertical or quasi-horizontal polarization from the Earth's atmosphere. The ATMS sensor data record algorithm employed a commonly used two-point calibration equation that derives the earth-view brightness temperature directly from the counts and temperatures of warm target and cold space, and the earth-scene count. This equation is only valid under Rayleigh-Jeans (RJ) approximation. Impacts of RJ approximation on ATMS calibration biases are evaluated in this study. It is shown that the RJ approximation used in ATMS radiometric calibration results in errors on the order of 1-2 K. The error is also scene count dependent and increases with frequency.

    Full Text Available Although Jean Paul Marat (1743-1793 is known as a political activist and as a founder of the controversial journal L'Ami du Peuple during the French Revolution, an important period of his life was spent as a medical practionner, and as a scientist. In 1765 he went to England, where he remained for eleven years mostly dedicated to medical practice and publications on that subject and on political and moral questions. Returning to France in 1776 he iniciated his researches on fire, electricity and light, that lasted practically until the French Revolution. In 1787 he published a translation of Newton's Opticks. In this article we describe in some detail his medical and scientific practice giving particular emphasis to his experiments on optics and to his theory about colors which strongly departs from newtonian theory, fully accepted by the French scientific community of the time.

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

    Science.gov (United States)

    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.

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

    Energy Technology Data Exchange (ETDEWEB)

    Bouchard, A.R.; Gagnon, M.J.

    1987-01-01

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

    Objective To know the facilities and the difficulties of nurses in caring practice of hospitalized children's families in the light of Jean Watson's Theory of Human Caring. Method It was used the descriptive qualitative approach. The data collection was conducted in three stages: presentation of theoretical content; engagement with families in the light of Watson's theory; and semi-structured interview with 12 pediatric nurses. The interviews were analysed using inductive thematic analysis, being possible to form three themes: Recognizing a framework for care; Considering the institutional context; and Challenges in family's relationship. Results The theory favored reflections about self, about the institutions and about nurses' relationship with the family of the child, normalized by a consciousness toward caring attitudes. Conclusion In this process, it is imperative that nurses recognize the philosophical-theoretical foundations of care to attend the child's family in hospital.

    Directory of Open Access Journals (Sweden)

    Alex Villas Boas

    2014-09-01

    Full Text Available This article proposes to examine some theories of non-religious spirituality in light of the growing phenomenon of those individuals who declared themselves as having "no religion" by Brazilian religious census conducted in 2010 by the Brazilian Institute of Geography and Statistics (IBGE. The intention here is to identify how the poetic question presents itself as the fundamental element of these proposals about spirituality for authors, since beauty is part of the spiritual quest, as in: Viktor Frankl and existential religiosity grounded in the search for meaning in life; Marià Corbí and his non-religious or secular spirituality; Robert Solomon and his spirituality for skeptics, and André Comte-Sponville and his atheistic spirituality, or spirituality without God. From there, we then present the perception of spirituality in the poetry of the thought of Jean Paul Sartre, primarily in his work “what is Literature?”

    Science.gov (United States)

    Cara, Chantal; O'Reilly, Louise

    2008-12-01

    Essentially based on humanistic values of respect, collaboration, and uniqueness rather than on objectification, control, and categorization of the person cared-for, a professional's practice rooted in caring is aimed at helping individuals and their families, which can only be carried out through respect for human dignity. If we are to consider caring as the core of nursing, nurses will undoubtedly have to make a conscious effort to preserve human caring within their clinical practice (Cara, 2004b; O'Reilly, 2008, Watson, 2002). However, to support this endeavour, caring theories, such as the one proposed by Jean Watson, are essential. Inspired by Cara's (2003) continuing education paper, this reflection paper takes a pragmatic approach to promote the understanding of key elements involved in Watson's caring theory through a process of reflective practice within a rehabilitation clinical situation.

  17. Aesthetics of Being: The Unfinished Memoirs of Virginia Woolf and Jean Rhys

    Directory of Open Access Journals (Sweden)

    Patricia Moran

    2010-01-01

    Full Text Available This essay reads the unfinished memoirs of Virginia Woolf and Jean Rhys through the lens of relational psychoanalysis, particularly that of Christopher Bollas. Building upon the latter's theorisation of a maternal aesthetic based on her handling of the infant, what Bollas terms the mother's "idiom of care", the essay traces both positive and negative registers of such an aesthetic. Both memoirs open with self-identified "first memories", and both go on to connect the act of writing with these first memories. Woolf's memoir foregrounds moments of containment in a uterine, preoedipal surround, "colour-and-sound" experiences shattered by the mother's sudden death: Woolf goes on to characterise her writing as a practice that allows her to rebuild the shattered world. Rhys, by contrast, connects her writing to experiences of disharmony, alienation, and estrangement, an aesthetic she traces back to her mother's insistence on a surface conformity, at odds with the daughter's inner turmoil.

    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.

    Full Text Available Objective To know the facilities and the difficulties of nurses in caring practice of hospitalized children’s families in the light of Jean Watson’s Theory of Human Caring. Method It was used the descriptive qualitative approach. The data collection was conducted in three stages: presentation of theoretical content; engagement with families in the light of Watson’s theory; and semi-structured interview with 12 pediatric nurses. The interviews were analysed using inductive thematic analysis, being possible to form three themes: Recognizing a framework for care; Considering the institutional context; and Challenges in family’s relationship. Results The theory favored reflections about self, about the institutions and about nurses’ relationship with the family of the child, normalized by a consciousness toward caring attitudes. Conclusion In this process, it is imperative that nurses recognize the philosophical-theoretical foundations of care to attend the child’s family in hospital.

  3. [The long and difficult birth of symphysiotomy or from Severin Pineau to Jean-Rene Sigault].

    Jean-René Sigault and his assistant Alphonse Le Roy first performed in Paris symphyseotomy on the 1st of october 1777 and thereby successfully delivered Madame Souchot. This patient had a rachitic pelvis with an antero-posterior diameter of 6.5 to 7 centimeters and had previously given birth to four dead children. In fact symphyseotomy had been advocated in 1597 by Séverin Pineau after his description of a diastasis of the pubis on a hanged pregnant woman and Ambroise Paré approved Pineau. The operation was performed many times after Sigault's report but was opposed by the famous French obstetrician Jean-Louis Baudelocque. The discussion was so bitter that the Parisian physicians became divided in two groups, cesareans and symphyseans. Symphyseotomy, as a result of poor technic and its use in unsuitable cases, soon fell into disrepute and was forgotten until 1863 when Morisani, in Italy, performed it again. The procedure was reintroduced in France in 1891 by Pinard, very impressed by the demonstration of the visiting Spinelli. Pinard, Farabeuf and Varnier described an "open sky" technic based on a precise anatomic study. At the same time, in 1893, Gigli, in Italy, performed a new operation called pubiotomy praised before in 1786 by Aitken in Edinburgh. It consisted in severing the pubic bone to one side of the symphysis by means of the "Gigli saw". In fact, cesarean section was the operation chosen in almost all the cases by the obstetricians, symphyseotomy and pubiotomy being generally discarded in view of their many complications: hemorrhage, urinary fistulas, walking troubles... A simple new method of symphyseotomy was described in 1920-1924 by Enrique Zarate of Buenos-Aires called "subcutaneous partial symphyseotomy" which respects the superior ligament and a part of the inferior ligament of the symphysis. Accurately realised, it is little dangerous and is still used sometimes in difficult cases in some remote countries.

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

    Full Text Available O texto se ocupa com a questão da interpretação da obra de Jean-Jacques Rousseau, em particular com suas referências sobre a dependência constitutiva em relação aos outros. Vista negativamente na crítica da cultura, mas positivamente nos esboços de um contrato social, o lugar dessa dependência constitutiva da confirmação e estima por parte dos outros está vinculada ao significado dado ao “amor próprio” nos diferentes textos; mas ela abre a possibilidade de interpretar Rousseau como um teórico do reconhecimento. O autor acompanha Rousseau em seu desenvolvimento teórico até o ponto em que ele se tornou consciente das exigências de uma forma sociocontratual, igualitária do reconhecimento mútuo, para depois expor a enorme influência que a ideia bipolar de Rousseau a respeito do reconhecimento social exerceu sobre a teoria social da modernidade: em sua variante negativa, a profunda necessidade dos seres humanos de sobrepujar os respectivos cossujeitos no grau de estima social, reinterpretada por Kant como sendo a força motriz do progresso cultural e social, e em sua variante positiva, o respeito mútuo entre iguais, desenvolvido por Fichte e Hegel na direção de uma teoria do reconhecimento relacionada ao direito e à moralidade. No final, Honneth discute o ceticismo com que Rousseau sempre viu a dependência de outros contida no “amor próprio”, deixando sem solução definitiva a tensão entre a ideia estoica de uma independência pessoal de toda avaliação alheia e a ideia intersubjetivista de uma profunda dependência do outro.

  6. 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

    this object of study has difficulties, which are evident in the different approaches to it, either objectivist or subjectivist ones. In order to contribute to such discussion, this study aims at analyzing how the existentialism of Jean-Paul Sartre approaches the processes of the constitution of the subject. The Sartrean perspective enriches Psychology because, by rejecting reductionisms, it offers a conception that does not dichotomize the phenomenon of objectification-subjectification, since it conceives the subject in the dialectical relation between objectivity and subjectivity. Sartre does not only suggest elements to understand body, consciousness and the world as a human and historical reality, but also elucidates how the subject, who is forged in intersubjectivity, constructs his/her personal and collective history. Keywords: psychology; constitution of the subject; existentialism; Jean-Paul Sartr

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

    Perry, Bruce; Donovan, Michael P.; Kelsey, Linda J.; Paterson, John; Statkiewicz, Walter; Allen, Robert D.

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

    Full Text Available Pendidikan dan filsafat tidak dapat dipisahkan satu dengan yang lainnya. Filsafat bagi pendidikan berperan sebagai pedoman yang memberikan arahan dan tujuan  pendidikan. Sedangkan pendidikan bagi filsafat merupakan suatu ‘ruang’ yang selalu memberinya tempat untuk hidup dan terus berkembang melalui kegiatan-kegiatan teoritis maupun praktis dalam pendidikan. Filsafat eksistensialisme Jean Paul Sartre dapat digunakan sebagai dasar pijakan  dalam kegiatan belajar mengajar di kelas. Menurut Sartre, manusia adalah individu yang bebas. Namun kebebasan yang dimilikinya selalu terbatasi dengan fakta akan adanya kebebasan individu lain. Manusia adalah bebas untuk melakukan dan mendefinisikan dirinya sendiri secara individual.  Manusia tidak lain adalah bagaimana ia menjadikan dirinya sendiri.  Belajar adalah menjadikan dirinya sendiri otonom dan menyadari adanya orang lain sehingga dapat menciptakan dunianya sendiri yang berarti bagi dirinya dan bagi kehidupan orang lain atau lingkungannya. Namun demikian, kita tetap harus selektif terhadap pemikiran Sartre tentang peniadaan Tuhan. Dalam merumuskan konsep kebebasan individu, Sartre mengasumsikan bahwa tanpa bantuan Tuhan, manusia dapat bebas mendefinisikan dirinya sendiri untuk mencapai tujuan hidupnya. Pandangan ini jelas bertentangan dengan falsafah dasar negara kita yaitu Pancasila sila Ketuhanan Yang Maha Esa.

    Full Text Available As the contemporary nation state order continues to produce genocide and destruction, and thereby refugees, and as the national and international landscape continues to see the existence of refugees as a political problem, Jean Améry’s 1966 essay “How Much Home Does a Person Need?” takes on a curious urgency. I say ‘curious’ because his own conclusions about the essay’s aims and accomplishments appear uncertain and oftentimes unclear (note how Améry himself surprisingly suggests that his remarks will have “little general validity” – a statement that will need to be properly situated. My aim in what follows, then, is twofold. First, I intend to make clear the rich, suggestive, but perhaps underdeveloped phenomenological assumptions involved in this essay. Second, I want to show—but, unfortunately, only show—how these assumptions and Améry’s analysis points to a problem at the heart of contemporary conceptions of statehood, one which demands significantly more discussion.

  15. 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.

  16. Jean-Charles Houzeau's Visual Magnitude Estimates from Jamaica in 1868

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

    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

    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.

    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.

    The care of the patient with gastrointestinal disease is complex and challenging. The reasons for the complexity are varied and different for each patient. Any of these variables can affect the nutritional health of the patient, an essential element of care that supports healing, recovery, and improved quality of life. A nutritional assessment, an evaluation of the patient's nutritional status, can be used to establish the patient's weight history, dietary habits, tolerances, and likes and dislikes. Intake and output values from this assessment provide information relating to the patient's ability to meet his or her nutritional requirements orally or whether alternate methods for nutrition support need be considered, such as a feeding tube or a central intravenous catheter. Parenteral nutrition is the intravenous nutrition supplementation required when the oral or enteral route for nutrition support is unavailable or impossible. In this article, a clinical case scenario for a 34-year-old man with a history of cancer and an extensive bowel resection will be presented to better explore the decision-making process for determining appropriate nutrition support. In addition, various issues the health practitioner needs to consider when managing the nutritional health of the complex gastrointestinal patient will be explored, relative to Jean Watson's Theory of Caring.

    Directory of Open Access Journals (Sweden)

    Tess Do

    2005-08-01

    Full Text Available This essay focuses on the work of the New Caledonian-born writer Jean Vanmai. His first two novels, Chan Dang and Fils de Chan Dang, describe the working conditions and exilic existence of the little known Chan Dang, the voluntary workers from Tonkin (North Vietnam who moved to New Caledonia many decades ago. Descended himself from a Chan Dang family, Vanmai wishes to preserve the memory of the Chan DangDang’s past. In writing the story of the Chan Dang, Vanmai sees himself as the guardian of the Chan Dang’s collective memory, a keeper and defender of their common past. The paper argues that Vanmai's depictions of the Chan Dang have two important effects. First, by sharing with other Vietnamese migrants/refugees the life and experiences of the Tonkinese voluntary workers in New Caledonia, Vanmai breaks the silence surrounding colonial exile and exploitation and provides a full account of the Chan Dang’s exile that can be integrated into the contemporary history of Vietnamese migration. Second, by using different narrative resolutions for each of his protagonists, Vanmai stresses the need to fulfil one’s filial duty among the young Vietnamese generations. With this symbolic filial act, Vanmai pays homage to his Vietnamese ancestors and earns himself a honourable title, that of a true dutiful "son of Chan Dang".

  8. METAFISIKA INFORMASI DALAM PERSPEKTIF PEMIKIRAN JEAN BAUDRILLARD: KONTEKSTUALISASINYA DENGAN PERTAUTAN MEDIA DAN POLITIK DI INDONESIA

    Full Text Available The 21st century is the age of information. Information spreads through newspapers, magazines, television; and also scattered very massively over the internet. This paper was written for two reasons. First, people sometimes perceive information identical with truth. Second, the metaphysics of information is important to be discussed when it is associated with the phenomenon of media and politics in Indonesia. This paper analyses the metaphysics of information by 'disclosing' information structures that refer to Jean Baudrillard's thought. For Baudrillard, behind the phenomenon of information there are actually three elements at once, namely representation, manipulation, and simulation. The three elements above, influence each other. Real information is the result of the process of representation, ie the process of re-preserving reality and then transmitting that representation of reality to others. Manipulation also becomes an important element in information. According to Baudrillard, the element of simulation in this information is still closely related to the first element, namely representation. Baudrillard said that in the simulation, information will be actualized, meaning that it will be dramatized in a spectacular fashion, but at the same time kept away from communication, and reduced to a sign.

  9. On the Jeans Theorem and the “Tolman–Oppenheimer–Volkoff Equation” in R2 Gravity

    Full Text Available Corda, Mosquera Cuesta, and Lorduy Gòmez have shown that spherically symmetric stationary states can be used as a model for galaxies in the framework of the linearized R2 gravity. Those states could represent a partial solution to the Dark Matter Problem. Here, we discuss an improvement of this work. In fact, as the star density is a functional of the invariants of the associated Vlasov equation, we show that any of these invariants is in its turn a functional of the local energy and the angular momentum. As a consequence, the star density depends only on these two integrals of the Vlasov system. This result is known as the “Jeans theorem.” In addition, we find an analogy of the historical Tolman–Oppenheimer–Volkoff equation for the system considered in this paper. For the sake of completeness, in the final section of the paper, we consider two additional models which argue that Dark Matter could not be an essential element.

    To report about the work of Prof. Jean-Raoul Scherrer, and show how his humanist vision, his medical skills and his scientific background have enabled and shaped the development of medical informatics over the last 30 years. Starting with the mainframe-based patient-centered hospital information system DIOGENE in the 70s, Prof. Scherrer developed, implemented and evolved innovative concepts of man-machine interfaces, distributed and federated environments, leading the way with information systems that obstinately focused on the support of care providers and patients. Through a rigorous design of terminologies and ontologies, the DIOGENE data would then serve as a basis for the development of clinical research, data mining, and lead to innovative natural language processing techniques. In parallel, Prof. Scherrer supported the development of medical image management, ranging from a distributed picture archiving and communication systems (PACS) to molecular imaging of protein electrophoreses. Recognizing the need for improving the quality and trustworthiness of medical information on the Web, Prof. Scherrer created the Health-On-the-Net (HON) foundation. These achievements, made possible thanks to his visionary mind, deep humanism, creativity, generosity and determination, have made of Prof. Scherrer a true pioneer and leader of the human-centered, patient-oriented application of information technology for improving healthcare.

    Full Text Available This work concerns the letter sent from the French College in Phillipopoli/Plovdiv (Bulgaria by Pater Joannes /Jean-Baptiste/ Thibaut, the French Byzantines — musicologist, to Tihomir Ostojić, professor at the Secondary school (Gymnasium in Novi Sad, a literature historian and expert on Traditional Serbian Church Chant. At that time Thibaut was widening his research interest in Byzantine Chant and neumatic notation, to include Slavonic Chant Tradition, first Russian Chant and later that of the Balkan peoples as well. He was one of the first foreigners to show interest in the Orthodox Chant Tradition of the Southern Slavs, and perceived that, contrary of the Russians, South Slavs never adopted early Byzantine neumatic notation. Visiting monasteries in Bulgaria he tried to find reasons for this lack of Byzantine notation among the Southern Slavs. In the above letter he posed very serious questions regarding Chant in the Serbian Orthodox Church, more precisely regarding the "Karlovci Chant". Unfortunately, it is not known if Thibaut received any kind of reply from Ostojić, nor have we found the reply sent to him by the Serbian Patriarch Georgije Branković, whom he also addressed, asking for help. Answers by those experts to the Thibaut's well formulated questions would be an extremely important contribution to studies of Traditional Serbian Church Chant.

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

    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.

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

    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 halos simulated in accordance with ΛCDM cosmology by Bullock and Johnston (2005) 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% and a dispersion of ˜14%. Additionally, the mass profiles of triaxial dark matter halos taken from the SURFS simulation, within scaled radius 0.2 < r/rmax < 3, are measured with a bias of ˜-2.4% and a dispersion of ˜10%. 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 halos, for example being aspherical and out-of-equilibrium. Hence the dispersion obtained for stellar halos sets a limit of about 12% (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.

    Full Text Available This paper explores the role of Troy in the space-time continuum of Jean Racine’s (1639-1699 two most widely known, secular tragedies „Iphigenia“ (1667 and „Andromache“ (1674. The tragic space-time continuum and its effect on the image of Troy is analysed according to the theory of operative devices. Stéphane Lojkine adapted this theory to the analysis of the space created by fictional texts. In the first section, the paper gives a brief overview of the history of the theory of operative devices and the principles and primary concepts involved, then describes the space-time of Racine’s tragedy as an operative device, which functions because the tensions created between the different zones and levels of space-time are mediated on a scopic level (i.e. the character’s viewpoints. The second section takes a closer look at how the images of the Trojan War that are created shift and change within these zones, depending on whether the events of war take place in the present or the future vis-à-vis the events of the tragedy.  In „Andromache“, Troy has already been destroyed. One of the Greek commanders, King Pyrrhus, is driven by sentimentality and wishes to restore it „within the walls“ of his kingdom. However, in „Iphigenia“, the characters are only just making preparations for war and their main desire is to be free of the curse of the gods that has rendered the waterway leading under the walls of Troy impenetrable. The male protagonists of both tragedies wish to bring Troy into their own, present space-time continuum. The conflicts in both tragedies revolve around a character who is the „key“ to Troy: in „Andromache“, it is Astyanax, the son of Hector, the dead king of Troy, and in „Iphigenia“, it is the main character’s double, Eriphyle, the daughter of beautiful Helen and Theseus. The delusional city in „Andromache“ materializes when Pyrrhus places the crown on Andromaque’s head, thereby ensuring

    Electrochemically formed hydrogen nanobubbles at a platinum rotating disk electrode (RDE) were detected by re-oxidation charge. The dissolution time course of the hydrogen nanobubbles was measured by AFM tapping topography under open-circuit conditions at stationary platinum and gold single-crystal electrodes. The bubble dissolution at platinum was much faster than that at gold because two types of diffusion, bulk and surface diffusion, proceeded at the platinum surface, whereas surface diffusion was prohibited at the gold electrode. These findings indicated that the electrochemical reaction of normal hydrogen electrode partly proceeded heterogeneously on the three-phase boundary around the hydrogen nanobubble.

    In this report the authors describe results from technical and economic assessments carried out during the past year with support from the USDOE Hydrogen R&D Program. (1) Assessment of technologies for small scale production of hydrogen from natural gas. Because of the cost and logistics of transporting and storing hydrogen, it may be preferable to produce hydrogen at the point of use from more readily available energy carriers such as natural gas or electricity. In this task the authors assess near term technologies for producing hydrogen from natural gas at small scale including steam reforming, partial oxidation and autothermal reforming. (2) Case study of developing a hydrogen vehicle refueling infrastructure in Southern California. Many analysts suggest that the first widespread use of hydrogen energy is likely to be in zero emission vehicles in Southern California. Several hundred thousand zero emission automobiles are projected for the Los Angeles Basin alone by 2010, if mandated levels are implemented. Assuming that hydrogen vehicles capture a significant fraction of this market, a large demand for hydrogen fuel could evolve over the next few decades. Refueling a large number of hydrogen vehicles poses significant challenges. In this task the authors assess near term options for producing and delivering gaseous hydrogen transportation fuel to users in Southern California including: (1) hydrogen produced from natural gas in a large, centralized steam reforming plant, and delivered to refueling stations via liquid hydrogen truck or small scale hydrogen gas pipeline, (2) hydrogen produced at the refueling station via small scale steam reforming of natural gas, (3) hydrogen produced via small scale electrolysis at the refueling station, and (4) hydrogen from low cost chemical industry sources (e.g. excess capacity in refineries which have recently upgraded their hydrogen production capacity, etc.).

    Full Text Available Pretendemos percorrer, com Jean-Luc Nancy, os principais momentos do processo de construção e desconstrução do cristianismo e do Ocidente, até o seu estado presente, consequência da “morte de Deus” como própria destinação do cristianismo. A desconstrução do cristianismo e, pela mesma ocasião, do Ocidente que se identifica com ele, objetiva reduzi-lo à essência do seu fenômeno. Trata-se do “desenclausuramento” ou da “declosão” recíproca das heranças da religião e da filosofia. Ao longo da história, por um movimento virtualmente infinito, a fé cristã se descobre remetendo a um momento anterior a ela mesma, momento que ela constantemente renova e clareia. Uma das principais tarefas é a desconstrução do monoteísmo.  Com a figura de Cristo, a renúncia ao poder divino e à sua presença torna-se o próprio ato de Deus. A ausência ou o vazio-de-divindade é sua verdade mais profunda. Mostraremos, também, algumas implicações éticas e políticas do processo. Concluiremos com algumas reflexões críticas a respeito do método adotado pelo autor e dos principais resultados do percurso.

    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.

Jean-Christophe Bailly se fait voyageur – Wanderer – et, à travers les lieux, les monuments, la population, ou encore les objets, l’on voit se dérouler sous nos yeux une « histoire des traces » : la reconstitution d’une identité grâce à des indices perçus au fil de voyages menés sur le territoire. L’œuvre se constitue pour une large part comme une enquête, bien que non systématique : elle est essai de « déchiffrement » des paysages français, tentative d’y apercevoir des « échos soulevés en passant » à partir desquels « l’intuition d’un récit » pourra naître. Une dynamique spécifique travaille ainsi en profondeur un texte au sein duquel deux systèmes sémiotiques s’imbriquent : le paysage d’une part, diffusant des signaux qui composent une image fluctuante et mobile de la France, image organisée, pour reprendre les termes de Bailly, comme une « pelote complexe et enchevêtrée où époques, affects et dimensions s’entremêlent » ; l’écriture d’autre part, qui essaye de rendre compte de la multiplicité et de la complexité de ce phénomène.

    Directory of Open Access Journals (Sweden)

    Diederik Aerts

    2009-01-01

    Full Text Available In this paper, we turn to the philosophy of Jean-Luc Nancy. In his work La Création du Monde ou la Mondialisation of 2002 the French philosopher analyses the process of globalisation. Rather than denoting a new homogeneity, the term refers to a world horizon characterized in its inter-palpable multiplicity of cultural, socio-economical, ideological and politico-moral content. According to Nancy, globalisation refers to ag-glome-ration: the decay of what once was a globe and now nothing more than a glome. On the one hand, Nancy indicates that the world has changed by an unknown increase of techno-science, the worsening of inequalities between growing populations and by the changing and disappearing of given certainties, views and identities of the world and of man. On a large scale, this deformation is due to the relation between the capitalist evolution and the capitalising of worldviews. On the other hand, due to the inter-palpability of the multiplicity, this means that on our planet there is only space for one world. The world gradually becomes the only world. In this paper we will investigate what Nancy means with the becoming-world of the world and how this relates to our being in the world. For Nancy globalisation reveals two possible destinies of our relation with the world. In La Création du Monde ou la Mondialisation he discerns globalisation from mondialisation to analyze these two possibilities. We will investigate this distinction of Nancy and its consequences for everyday life.

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

    Science.gov (United States)

    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].

    Full Text Available Abstract The limited fossil fuel prompts the prospecting of various unconventional energy sources to take over the traditional fossil fuel energy source. In this respect the use of hydrogen gas is an attractive alternate source. Attributed by its numerous advantages including those of environmentally clean, efficiency and renew ability, hydrogen gas is considered to be one of the most desired alternate. Cyanobacteria are highly promising microorganism for hydrogen production. In comparison to the traditional ways of hydrogen production (chemical, photoelectrical, Cyanobacterial hydrogen production is commercially viable. This review highlights the basic biology of cynobacterial hydrogen production, strains involved, large-scale hydrogen production and its future prospects. While integrating the existing knowledge and technology, much future improvement and progress is to be done before hydrogen is accepted as a commercial primary energy source.

    Composite hydrogen transport membranes, which are used for extraction of hydrogen from gas mixtures are provided. Methods are described for supporting metals and metal alloys which have high hydrogen permeability, but which are either too thin to be self supporting, too weak to resist differential pressures across the membrane, or which become embrittled by hydrogen. Support materials are chosen to be lattice matched to the metals and metal alloys. Preferred metals with high permeability for hydrogen include vanadium, niobium, tantalum, zirconium, palladium, and alloys thereof. Hydrogen-permeable membranes include those in which the pores of a porous support matrix are blocked by hydrogen-permeable metals and metal alloys, those in which the pores of a porous metal matrix are blocked with materials which make the membrane impervious to gases other than hydrogen, and cermets fabricated by sintering powders of metals with powders of lattice-matched ceramic.

    1995-09-01

    Following are the major accomplishments of the 6th year`s study of biological hydrogen photoproduction which were supported by DOE/NREL. (1) We have been characterizing a biological hydrogen production system using synchronously growing aerobically nitrogen-fixing unicellular cyanobacterium, Synechococcus sp. Miami BG 043511. So far it was necessary to irradiate the cells to produce hydrogen. Under darkness they did not produce hydrogen. However, we found that, if the cells are incubated with oxygen, they produce hydrogen under the dark. Under 80% argon + 20% oxygen condition, the hydrogen production activity under the dark was about one third of that under the light + argon condition. (2) Also it was necessary so far to incubate the cells under argon atmosphere to produce hydrogen in this system. Argon treatment is very expensive and should be avoided in an actual hydrogen production system. We found that, if the cells are incubated at a high cell density and in a container with minimum headspace, it is not necessary to use argon for the hydrogen production. (3) Calcium ion was found to play an important role in the mechanisms of protection of nitrogenase from external oxygen. This will be a clue to understand the reason why the hydrogen production is so resistant to oxygen in this strain. (4) In this strain, sulfide can be used as electron donor for the hydrogen production. This result shows that waste water can be used for the hydrogen production system using this strain.

  15. A Thermodynamic History of the Solar Constitution — II: The Theory of a Gaseous Sun and Jeans' Failed Liquid Alternative

    Full Text Available In this work, the development of solar theory is followed from the concept that the Sun was an ethereal nuclear body with a partially condensed photosphere to the creation of a fully gaseous object. An overview will be presented of the liquid Sun. A powerful lineage has brought us the gaseous Sun and two of its main authors were the direct sci- entific descendants of Gustav Robert Kirchhoff: Franz Arthur Friedrich Schuster and Arthur Stanley Eddington. It will be discovered that the seminal ideas of Father Secchi and Herv ́ e Faye were not abandoned by astronomy until the beginning of 20th century. The central role of carbon in early solar physics will also be highlighted by revisit- ing George Johnstone Stoney. The evolution of the gaseous models will be outlined, along with the contributions of Johann Karl Friedrich Z ̈ ollner, James Clerk Maxwell, Jonathan Homer Lane, August Ritter, William Thomson, William Huggins, William Edward Wilson, George Francis FitzGerald, Jacob Robert Emden, Frank Washington Very, Karl Schwarzschild, and Edward Arthur Milne. Finally, with the aid of Edward Arthur Milne, the work of James Hopwood Jeans, the last modern advocate of a liquid Sun, will be rediscovered. Jeans was a staunch advocate of the condensed phase, but deprived of a proper building block, he would eventually abandon his non-gaseous stars. For his part, Subrahmanyan Chandrasekhar would spend nine years of his life studying homogeneous liquid masses. These were precisely the kind of objects which Jeans had considered for his liquid stars.

    Science.gov (United States)

    Engelmann, Lukas

    2012-03-01

    The article examines the meaning and function of medical illustrations in the famous Atlas Anatomie pathologique, published by the French surgeon Jean Cruveilhier (1791-1874). By tracing the complex representation of pathological entities both back to the visual tradition of anatomy and the semiotic tradition of case descriptions and case histories, the article identifies the visualization technique of Cruveilhier as an analytical practice. The illustration of pathological anatomy gains a functional diagnostic quality when bound to case descriptions and clinical histories. The Atlas serves thereby as a sample to trace the genealogies of a clinical visualization practice in characteristic images that is both engaged with an individual case and classificational tasks.

  1. Neuroplasticity and the brain connectome: what can Jean Talairach's reflections bring to modern psychosurgery?

    Science.gov (United States)

    Bourdillon, Pierre; Apra, Caroline; Lévêque, Marc; Vinckier, Fabien

    2017-09-01

    Contrary to common psychosurgical practice in the 1950s, Dr. Jean Talairach had the intuition, based on clinical experience, that the brain connectome and neuroplasticity had a role to play in psychosurgery. Due to the remarkable progress of pharmacology at that time and to the technical limits of neurosurgery, these concepts were not put into practice. Currently, these concepts are being confirmed by modern techniques such as neuroimaging and computational neurosciences, and could pave the way for therapeutic innovation in psychiatry. Psychosurgery commonly uses a localizationist approach, based on the idea that a lesion to a specific area is responsible for a deficit opposite to its function. To psychosurgeons such as Walter Freeman, who performed extensive lesions causing apparently inevitable deficit, Talairach answered with clinical data: complex psychic functions cannot be described that simply, because the same lesion does not provoke the same deficit in different patients. Moreover, cognitive impairment did not always follow efficacious psychosurgery. Talairach suggested that selectively destructing part of a network could open the door to a new organization, and that early psychotherapy could encourage this psychoplasticity. Talairach did not have the opportunity to put these concepts into practice in psychiatric diseases because of the sudden availability of neuroleptics, but connectomics and neuroplasticity gave rise to major advances in intraparenchymal neurosurgery, from epilepsy to low-grade glioma. In psychiatry, alongside long-standing theories implicating focal lesions and diffuse pathological processes, neuroimaging techniques are currently being developed. In mentally healthy individuals, combining diffusion tensor imaging with functional MRI, magnetoencephalography, and electroencephalography allows the determination of a comprehensive map of neural connections in the brain on many spatial scales, the so-called connectome. Ultimately, global

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

    Full Text Available Ideile lui Rousseau au avut un impact major asupra societăţii la sfârşitul sec. al XVIII-lea şi pe parcursul întregii perioade a sec. al XIX-lea. Aceste idei au imprimat un suflu modern cugetului său, fiind considerat şi un ideologist politic, o voce puternică a Revoluţiei Franceze şi un pioner al curentului romantic. În legătură cu domeniul nostru de studiu, paradoxurile concepţiei politice ale lui Rousseau se referă la contradicţia dintre aspiraţiile modernităţii şi criticile violente ale progresului social. El pune accentul pe contradicţia dintre încrede-rea deplină în ,,contractul social”, ca pattern cultural şi lipsa de încredere în ,,educaţia socială”. Unicul mod de a depăşi aceste contradicţii este abordarea noului model al filosofiei educaţiei bazat pe reforme radicale pentru a facilita autodezvoltarea individului.   THE PARADOXES OF POLITICAL CONCEPTION IN THE WORK OF JEAN-JACQUES ROUSSEAUHis ideas have a big impact on the society at the end of the 18th century and the whole 19th century period.

Related to our article subject, Rousseau's political conceptual paradoxes refer to the contradiction between moderni-ty aspiration and the violent critic of the social progress. He emphasizes the contradiction between full trust of the "social contract", as a cultural pattern and the distrust of the "social education." The only way to leave the contradictions behind is his new education philosophy pattern based on a radical reform in order for the individual to develop himself.

    1990-01-01

    The disposal of hydrogen is often required in the operation of an experimental facility that contains hydrogen. Whether the vented hydrogen can be discharged to the atmosphere safely depends upon a number of factors such as the flow rate and atmospheric conditions. Calculations have been made that predict the distance a combustible mixture can extend from the point of release under some specified atmospheric conditions. Also the quantity of hydrogen in the combustible cloud is estimated. These results can be helpful in deciding of the hydrogen can be released directly to the atmosphere, or if it must be intentionally ignited. 15 refs., 5 figs., 2 tabs.

  7. Hydrogen storage methods

    Science.gov (United States)

    Züttel, Andreas

    Hydrogen exhibits the highest heating value per mass of all chemical fuels. Furthermore, hydrogen is regenerative and environmentally friendly. There are two reasons why hydrogen is not the major fuel of today's energy consumption. First of all, hydrogen is just an energy carrier. And, although it is the most abundant element in the universe, it has to be produced, since on earth it only occurs in the form of water and hydrocarbons. This implies that we have to pay for the energy, which results in a difficult economic dilemma because ever since the industrial revolution we have become used to consuming energy for free. The second difficulty with hydrogen as an energy carrier is its low critical temperature of 33 K (i.e. hydrogen is a gas at ambient temperature). For mobile and in many cases also for stationary applications the volumetric and gravimetric density of hydrogen in a storage material is crucial. Hydrogen can be stored using six different methods and phenomena: (1) high-pressure gas cylinders (up to 800 bar), (2) liquid hydrogen in cryogenic tanks (at 21 K), (3) adsorbed hydrogen on materials with a large specific surface area (at Tchemically bonded in covalent and ionic compounds (at ambient pressure), or (6) through oxidation of reactive metals, e.g. Li, Na, Mg, Al, Zn with water. The most common storage systems are high-pressure gas cylinders with a maximum pressure of 20 MPa (200 bar). New lightweight composite cylinders have been developed which are able to withstand pressures up to 80 MPa (800 bar) and therefore the hydrogen gas can reach a volumetric density of 36 kg.m-3, approximately half as much as in its liquid state. Liquid hydrogen is stored in cryogenic tanks at 21.2 K and ambient pressure. Due to the low critical temperature of hydrogen (33 K), liquid hydrogen can only be stored in open systems. The volumetric density of liquid hydrogen is 70.8 kg.m-3, and large volumes, where the thermal losses are small, can cause hydrogen to reach a

    Hydrogen is an environmentally attractive transportation fuel that has the potential to displace fossil fuels. The Freedom CAR and Freedom FUEL initiatives emphasize the importance of hydrogen as a future transportation fuel. Presently, Las Vegas has one hydrogen fueling station powered by natural gas. However, the use of traditional sources of energy to produce hydrogen does not maximize the benefit. The hydrogen fueling station developed under this grant used electrolysis units and solar energy to produce hydrogen fuel. Water and electricity are furnished to the unit and the output is hydrogen and oxygen. Three vehicles were converted to utilize the hydrogen produced at the station. The vehicles were all equipped with different types of technologies. The vehicles were used in the day-to-day operation of the Las Vegas Valley Water District and monitoring was performed on efficiency, reliability and maintenance requirements. The research and demonstration utilized for the reconfiguration of these vehicles could lead to new technologies in vehicle development that could make hydrogen-fueled vehicles more cost effective, economical, efficient and more widely used. In order to advance the development of a hydrogen future in Southern Nevada, project partners recognized a need to bring various entities involved in hydrogen development and deployment together as a means of sharing knowledge and eliminating duplication of efforts. A road-mapping session was held in Las Vegas in June 2006. The Nevada State Energy Office, representatives from DOE, DOE contractors and LANL, NETL, NREL were present. Leadership from the National hydrogen Association Board of Directors also attended. As a result of this session, a roadmap for hydrogen development was created. This roadmap has the ability to become a tool for use by other road-mapping efforts in the hydrogen community. It could also become a standard template for other states or even countries to approach planning for a hydrogen

    2015-12-01

    Full Text Available This paper examines how the Front National’s electoral victories could be explained, partially, in terms of a new discursive rhetoric adopted by Marine Le Pen. In order to compare rhetorical strategies used by both Marine and Jean-Marie Le Pen and their impact on their followers, we use comparable data, which consist of press articles published during the presidential campaigns of each politician and postings by online discussants related to interviews. Using corpus linguistics tools and lexical semantics, we assess how differently both leaders position themselves emotionally and how this emotional positioning is reconstructed within the postings of the viewers. Although no important quantitative difference can be observed in the number of emotion key-words they used respectively, a shift in both politicians’ rhetoric positioning can be observed when analyzing the context in which these keywords are embedded. If Jean-Marie Le Pen focuses on negative feelings towards the Other (anger, resentment, Marine Le Pen promotes a positive ethos (empathy in order to detoxify the image of her party and broaden her electoral base.

    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

    For several years, researchers at Princeton University`s Center for Energy and Environmental Studies have carried out technical and economic assessments of hydrogen energy systems. Initially, we focussed on the long term potential of renewable hydrogen. More recently we have explored how a transition to renewable hydrogen might begin. The goal of our current work is to identify promising strategies leading from near term hydrogen markets and technologies toward eventual large scale use of renewable hydrogen as an energy carrier. Our approach has been to assess the entire hydrogen energy system from production through end-use considering technical performance, economics, infrastructure and environmental issues. This work is part of the systems analysis activity of the DOE Hydrogen Program. In this paper we first summarize the results of three tasks which were completed during the past year under NREL Contract No. XR-11265-2: in Task 1, we carried out assessments of near term options for supplying hydrogen transportation fuel from natural gas; in Task 2, we assessed the feasibility of using the existing natural gas system with hydrogen and hydrogen blends; and in Task 3, we carried out a study of PEM fuel cells for residential cogeneration applications, a market which might have less stringent cost requirements than transportation. We then give preliminary results for two other tasks which are ongoing under DOE Contract No. DE-FG04-94AL85803: In Task 1 we are assessing the technical options for low cost small scale production of hydrogen from natural gas, considering (a) steam reforming, (b) partial oxidation and (c) autothermal reforming, and in Task 2 we are assessing potential markets for hydrogen in Southern California.

Iwatani Corporation broke through industry stereotypes by creating and building Hydro Edge Co. Ltd., Japan's largest liquid hydrogen plant. It was established in 2006 as a joint venture between Iwatani and Kansai Electric Power Group in Osaka. Hydro Edge is Japan's first combined liquid hydrogen and ASU plant, and is fully operational. Liquid oxygen, liquid nitrogen and liquid argon are separated from air using the cryogenic energy of liquefied natural gas fuel that is used for power generation. Liquid hydrogen is produced efficiently and simultaneously using liquid nitrogen. Approximately 12 times as much hydrogen in liquid form can be transported and supplied as pressurized hydrogen gas. This technology is a significant step forward in the dissemination and expansion of hydrogen in a hydrogen-based economy.

    The primary purpose of this paper is to stimulate theoretical predictions of how to retain metastably hydrogenous materials made at high pressure P on release to ambient. Ultracondensed metallic hydrogen has been made at high pressures in the fluid and reported made probably in the solid. Because the long quest for metallic hydrogen is likely to be concluded in the relatively near future, a logical question is whether another research direction, comparable in scale to the quest for metallic H, will arise in high pressure research. One possibility is retention of metastable solid metallic hydrogen and other hydrogenous materials on release of dynamic and static high pressures P to ambient. If hydrogenous materials could be retained metastably on release, those materials would be a new class of materials for scientific investigations and technological applications. This paper is a review of the current situation with the synthesis of metallic hydrogen, potential technological applications of metastable metallic H and other hydrogenous materials at ambient, and general background of published experimental and theoretical work on what has been accomplished with metastable phases in the past and thus what might be accomplished in the future.

    Conventional compressors have not been able to meet DOE targets for hydrogen refueling stations. They suffer from high capital cost, poor reliability and pose a risk of fuel contamination from lubricant oils. This project has significantly advanced the development of solid state hydrogen compressor technology for multiple applications. The project has achieved all of its major objectives. It has demonstrated capability of Electrochemical Hydrogen Compression (EHC) technology to potentially meet the DOE targets for small compressors for refueling sites. It has quantified EHC cell performance and durability, including single stage hydrogen compression from near-atmospheric pressure to 12,800 psi and operation of EHC for more than 22,000 hours. Capital cost of EHC was reduced by 60%, enabling a path to meeting the DOE cost targets for hydrogen compression, storage and delivery ($2.00-2.15/gge by 2020).

  15. Absurdity and being-in-itself. The third phase of phenomenology: Jean-Paul Sartre and existential psychoanalysis.

    Science.gov (United States)

    2001-08-01

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

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

    Science.gov (United States)

    Green, A

    1991-12-01

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

    Full Text Available The aim of the article is to present the story of the relationship between Jean-Léon Gérôme and Stanisław Chlebowski. The reconstruction of their friendship is partly based on yet unpublished source materials on the life and work of Chlebowski. The artists met in the early 1860s. Their acquaintance became closer in 1875 when Gérôme stayed in Istanbul at Chlebowski's house. When Chlebowski moved to France, Gérôme introduced him to the French artistic circles, offered him advice and suggested themes for his work. Their relationship was interrupted by Chlebowski's disease and his return to Poland. The last note of this friendship was the short story by Léontine de Nittis, published in 1892.

    Full Text Available The role of Jean Purdy in the work leading to the birth of Louise Brown is assessed. We report that Purdy: (i recorded and organized most of the data systematically; (ii probably spent longer working in Oldham than did Edwards; (iii whilst there, was primarily responsible for organizing laboratory supplies, including media preparation and testing; (iv was involved in patient care; and (v was a major source of support to Edwards. We find that Purdy, despite her nursing qualification, was not involved in laparoscopic egg retrieval and clinical aspects, but was focused on basic research activities. The evidence on who was present at embryo transfers is less clear, but suggests that Edwards was present for all, whereas Purdy may have been absent for some. Overall, we conclude that Purdy’s role was a highly significant and under-appreciated element in the achievement of IVF in Oldham.

    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.

  5. Chlorific efficiency of coal hydrogenation

    Energy Technology Data Exchange (ETDEWEB)

    Schappert, H.

    1942-10-20

    In studies on the calorific efficiency of coal hydrogenation, the efficiency for H/sub 2/ production was calculated to be 26%, the efficiency for hydrogenation was calculated to be 49%, and the efficiency of hydrogenation including H/sub 2/ production was 27.2%. The efficiency of hydrogenation plus hydrogen production was almost equal to the efficiency of hydrogen production alone, even though this was not expected because of the total energy calculated in the efficiency of hydrogenation proper. It was entirely possible, but did not affect computations, that the efficiency of one or the other components of hydrogenation process differed somewhat from 49%. The average efficiency for all cases was 49%. However, when hydrogen was not bought, but was produced--(efficiency of hydrogen production was 26%, not 100%-- then the total energy changed and the efficiency of hydrogen production and combination was not 26%, but 13%. This lower value explained the drop of hydrogenation efficiency to 27.2%.

    'Full text:' The Hydrogen Highway in British Columbia, Canada, is a coordinated, large-scale demonstration and deployment program aimed at accelerating the commercialization of hydrogen and fuel cell technologies and products. It will be a showcase for fuel cell vehicles, refuelling stations and stationary power systems leading up to the 2010 Olympic and Paralympic Winter Games in Whistler, BC. The Hydrogen Highway is designed to help address many of the challenges to commercialization identified in the Canadian Fuel Cell Commercialization Roadmap. The project will create an early adopter network of hydrogen and fuel cell microenvironments where technology developers and users can learn about the technical, economic, environmental and social impacts of products. The Hydrogen Highway will give the public and potential purchasers an opportunity to feel, touch and see the new technology, as well as provide the industry with a venue in which to develop industry standards and supply chains of materials and components. While demonstration and deployment programs are a recognized and necessary component in the process to commercialize hydrogen and fuel cell technologies, there is no handbook describing how it should be done. This paper will describe the history, objectives, project details and some of the challenges associated with establishing Canada's Hydrogen Highway. (author)

    Rocheleau, R.; Misra, A.; Miller, E. [Univ. of Hawaii, Honolulu, HI (United States)

    1998-08-01

    A significant component of the US DOE Hydrogen Program is the development of a practical technology for the direct production of hydrogen using a renewable source of energy. High efficiency photoelectrochemical systems to produce hydrogen directly from water using sunlight as the energy source represent one of the technologies identified by DOE to meet this mission. Reactor modeling and experiments conducted at UH provide strong evidence that direct solar-to-hydrogen conversion efficiency greater than 10% can be expected using photoelectrodes fabricated from low-cost, multijunction (MJ) amorphous silicon solar cells. Solar-to-hydrogen conversion efficiencies as high as 7.8% have been achieved using a 10.3% efficient MJ amorphous silicon solar cell. Higher efficiency can be expected with the use of higher efficiency solar cells, further improvement of the thin film oxidation and reduction catalysts, and optimization of the solar cell for hydrogen production rather than electricity production. Hydrogen and oxygen catalysts developed under this project are very stable, exhibiting no measurable degradation in KOH after over 13,000 hours of operation. Additional research is needed to fully optimize the transparent, conducting coatings which will be needed for large area integrated arrays. To date, the best protection has been afforded by wide bandgap amorphous silicon carbide films.

  10. A green hydrogen economy

    2006-11-15

    This paper is the result of over a dozen scholars and practitioners who strongly felt that a hydrogen economy and hence the future is closer than some American politicians and bureaucrats state. Moreover, when seen internationally, there is strong evidence, the most recent and obvious ones are the proliferation of hybrid vehicles, that for any nation-state to be energy independent it must seek a renewable or green hydrogen future in the near term. The State of California has once again taken the lead in this effort for both an energy-independent future and one linked strongly to the hydrogen economy. Then why a hydrogen economy in the first instance? The fact is that hydrogen most likely will not be used for refueling of vehicles in the near term. The number of vehicles to make hydrogen commercially viable will not be in the mass market by almost all estimates until 2010. However, it is less than a decade away. The time frame is NOT 30-40 years as some argue. The hydrogen economy needs trained people, new ventures and public-private partnerships now. The paper points out how the concerns of today, including higher costs and technologies under development, can be turned into opportunities for both the public and private sectors. It was not too long ago that the size of a mobile phone was that of a briefcase, and then almost 10 years ago, the size of a shoe box. Today, they are not only the size of a man's wallet but also often given away free to consumers who subscribe or contract for wireless services. While hydrogen may not follow this technological commercialization exactly, it certainly will be on a parallel path. International events and local or regional security dictate that the time for a hydrogen must be close at hand. (author)

    Biological hydrogen production can be accomplished by either thermochemical (gasification) conversion of woody biomass and agricultural residues or by microbiological processes that yield hydrogen gas from organic wastes or water. Biomass gasification is a well established technology; however, the synthesis gas produced, a mixture of CO and H{sub 2}, requires a shift reaction to convert the CO to H{sub 2}. Microbiological processes can carry out this reaction more efficiently than conventional catalysts, and may be more appropriate for the relatively small-scale of biomass gasification processes. Development of a microbial shift reaction may be a near-term practical application of microbial hydrogen production.

    Intermetallic compounds with the CaCu.sub.5 type of crystal structure, particularly LaNiCo.sub.4 and CaNi.sub.5, exhibit high separation factors and fast equilibrium times and therefore are useful for packing a chromatographic hydrogen isotope separation colum. The addition of an inert metal to dilute the hydride improves performance of the column. A large scale mutli-stage chromatographic separation process run as a secondary process off a hydrogen feedstream from an industrial plant which uses large volumes of hydrogen can produce large quantities of heavy water at an effective cost for use in heavy water reactors.

    During the Space Shuttle Program, one of the most hazardous operation that occurred was the loading of liquid hydrogen (LH2) during fueling operations of the spacecraft. Due to hydrogen's low explosive limit, any amount leaked could lead to catastrophic event. Hydrogen's chemical properties make it ideal as a rocket fuel; however, the fuel is deemed unsafe for most commercial use because of the inability to easily detect the gas leaking. The increased use of hydrogen over traditional fossil fuels would reduce greenhouse gases and America's dependency on foreign oil. Therefore a technology that would improve safety at NASA and in the commercial sector while creating a new economic sector would have a huge impact to NASA's mission. The Chemochromic Detector for sensing hydrogen gas leakage is a color-changing detector that is useful in any application where it is important to know not only the presence but also the location of the hydrogen gas leak. This technology utilizes a chemochromicpigment and polymer matrix that can be molded or spun into rigid or pliable shapes useable in variable temperature environments including atmospheres of inert gas, hydrogen gas, or mixtures of gases. A change in color of the detector material indicates where gaseous hydrogen leaks are occurring. The irreversible sensor has a dramatic color change from beige to dark grey and remains dark grey after exposure. A reversible pigment changes from white to blue in the presence of hydrogen and reverts back to white in the presence of oxygen. Both versions of the sensor's pigments were comprised of a mixture of a metal oxide substrate and a hydro-chromic compound (i.e., the compound that changed color in the presence of hydrogen) and immediately notified the operator of the presence of low levels of hydrogen. The detector can be used in a variety of formats including paint, tape, caulking, injection molded parts, textiles and fabrics, composites, and films. This technology brings numerous

  17. Biomimetic hydrogen production

    Hydrogenases catalyze the reduction of protons to molecular hydrogen with outstanding efficiency. An electrode surface which is covered with active hydrogenase molecules becomes a promising alternative to platinum for electrochemical hydrogen production. To immobilize the hydrogenase on the electrode, the gold surface was modified by heterobifunctional molecules. A thiol headgroup on one side allowed the binding to the gold surface and the formation of a self-assembled monolayer. The other side of the molecules provided a surface with a high affinity for the hydrogenase CrHydA1 from Chlamydomonas reinhardtii. With methylviologen as a soluble energy carrier, electrons were transferred from carboxy-terminated electrodes to CrHydA1 and conducted to the active site (H-cluster), where they reduce protons to molecular hydrogen. A combined approach of surface-enhanced infrared absorption spectroscopy, gas chromatography, and surface plasmon resonance allowed quantifying the hydrogen production on a molecular level. Hydrogen was produced with a rate of 85 mol H{sub 2} min{sup -1} mol{sup -1}. On a 1'- benzyl-4,4'-bipyridinum (BBP)-terminated surface, the electrons were mediated by the monolayer and no soluble electron carrier was necessary to achieve a comparable hydrogen production rate (approximately 50% of the former system). The hydrogen evolution potential was determined to be -335 mV for the BBP-bound hydrogenase and -290 mV for the hydrogenase which was immobilized on a carboxy-terminated mercaptopropionic acid SAM. Therefore, both systems significantly reduce the hydrogen production overpotential and allow electrochemical hydrogen production at an energy level which is close to the commercially applied platinum electrodes (hydrogen evolution potential of -270 mV). In order to couple hydrogen production and photosynthesis, photosystem I (PS1) from Synechocystis PCC 6803 and membrane-bound hydrogenase (MBH) from Ralstonia eutropha were bound to each other

    The large-scale production of hydrogen utilizing energy provided by a renewable source to split water is one of the most ambitious long-term goals of the U.S. Department of Energy`s Hydrogen Program. One promising option to meet this goal is direct photoelectrolysis in which light absorbed by semiconductor-based photoelectrodes produces electrical power internally to split water into hydrogen and oxygen. Under this program, direct solar-to-chemical conversion efficiencies as high as 7.8 % have been demonstrated using low-cost, amorphous-silicon-based photoelectrodes. Detailed loss analysis models indicate that solar-to-chemical conversion greater than 10% can be achieved with amorphous-silicon-based structures optimized for hydrogen production. In this report, the authors describe the continuing progress in the development of thin-film catalytic/protective coatings, results of outdoor testing, and efforts to develop high efficiency, stable prototype systems.

  2. Water's Hydrogen Bond Strength

    Water is necessary both for the evolution of life and its continuance. It possesses particular properties that cannot be found in other materials and that are required for life-giving processes. These properties are brought about by the hydrogen bonded environment particularly evident in liquid water. Each liquid water molecule is involved in about four hydrogen bonds with strengths considerably less than covalent bonds but considerably greater than the natural thermal energy. These hydrogen bonds are roughly tetrahedrally arranged such that when strongly formed the local clustering expands, decreasing the density. Such low density structuring naturally occurs at low and supercooled temperatures and gives rise to many physical and chemical properties that evidence the particular uniqueness of liquid water. If aqueous hydrogen bonds were actually somewhat stronger then water would behave similar to a glass, whereas if they were weaker then water would be a gas and only exist as a liquid at sub-zero temperature...

    A hydrogen sensor element comprises an essentially inert, electrically-insulating substrate having a thin-film metallization deposited thereon which forms at least two resistors on the substrate. The metallization comprises a layer of Pd or a Pd alloy for sensing hydrogen and an underlying intermediate metal layer for providing enhanced adhesion of the metallization to the substrate. An essentially inert, electrically insulating, hydrogen impermeable passivation layer covers at least one of the resistors, and at least one of the resistors is left uncovered. The difference in electrical resistances of the covered resistor and the uncovered resistor is related to hydrogen concentration in a gas to which the sensor element is exposed. 6 figs.

    Hydrogen is often proposed as the fuel of the future, but the transformation from the present fossil fuel economy to a hydrogen economy will need the solution of numerous complex scientific and technological issues, which will require several decades to be accomplished. Hydrogen is not an alternative fuel, but an energy carrier that has to be produced by using energy, starting from hydrogen-rich compounds. Production from gasoline or natural gas does not offer any advantage over the direct use of such fuels. Production from coal by gasification techniques with capture and sequestration of CO₂ could be an interim solution. Water splitting by artificial photosynthesis, photobiological methods based on algae, and high temperatures obtained by nuclear or concentrated solar power plants are promising approaches, but still far from practical applications. In the next decades, the development of the hydrogen economy will most likely rely on water electrolysis by using enormous amounts of electric power, which in its turn has to be generated. Producing electricity by burning fossil fuels, of course, cannot be a rational solution. Hydroelectric power can give but a very modest contribution. Therefore, it will be necessary to generate large amounts of electric power by nuclear energy of by renewable energies. A hydrogen economy based on nuclear electricity would imply the construction of thousands of fission reactors, thereby magnifying all the problems related to the use of nuclear energy (e.g., safe disposal of radioactive waste, nuclear proliferation, plant decommissioning, uranium shortage). In principle, wind, photovoltaic, and concentrated solar power have the potential to produce enormous amounts of electric power, but, except for wind, such technologies are too underdeveloped and expensive to tackle such a big task in a short period of time. A full development of a hydrogen economy needs also improvement in hydrogen storage, transportation and distribution

    The Hydrogen Systems Laboratory in a unique partnership between Purdue University's main campus in West Lafayette and the Calumet campus was established and its capabilities were enhanced towards technology demonstrators. The laboratory engaged in basic research in hydrogen production and storage and initiated engineering systems research with performance goals established as per the USDOE Hydrogen, Fuel Cells, and Infrastructure Technologies Program. In the chemical storage and recycling part of the project, we worked towards maximum recycling yield via novel chemical selection and novel recycling pathways. With the basic potential of a large hydrogen yield from AB, we used it as an example chemical but have also discovered its limitations. Further, we discovered alternate storage chemicals that appear to have advantages over AB. We improved the slurry hydrolysis approach by using advanced slurry/solution mixing techniques. We demonstrated vehicle scale aqueous and non-aqueous slurry reactors to address various engineering issues in on-board chemical hydrogen storage systems. We measured the thermal properties of raw and spent AB. Further, we conducted experiments to determine reaction mechanisms and kinetics of hydrothermolysis in hydride-rich solutions and slurries. We also developed a continuous flow reactor and a laboratory scale fuel cell power generation system. The biological hydrogen production work summarized as Task 4.0 below, included investigating optimal hydrogen production cultures for different substrates, reducing the water content in the substrate, and integrating results from vacuum tube solar collector based pre and post processing tests into an enhanced energy system model. An automated testing device was used to finalize optimal hydrogen production conditions using statistical procedures. A 3 L commercial fermentor (New Brunswick, BioFlo 115) was used to finalize testing of larger samples and to consider issues related to scale up

    This method for the production of high-quality electrode coke involved the hydrogenation of coal to a filterable bitumen product. The hydrogenation and splitting processes were carried out to end at high-molecular-weight bitumens with some lighter oils produced. Variations in temperature, pressure, and throughput determined the type and amount of bitumens. Proper conditions allowed sufficient middle oil for recirculation as pasting oil as well as for increasing filterability by dilution. This partial hydrogenation could be performed without the addition of hydrogen, if hydrogen-producing aromatic compounds, such as tetraline or cresol, were used as pasting oils. For 700-atm hydrogenation, it was found that the Upper Silesian coal was the best with respect to yield, filterability, and recovery of the recycle oils. The lower pressures gave a better filterability while sacrificing yield and recycle oil. The more severe the hydrogenating conditions, the lighter the bitumens and the lower the melting point. For the range of 300 to 600 atm, it was found that filterability improved with increased temperature and decreased with a pressure gain. Larger throughputs caused relatively moderate decreases in filterability. The use of iron catalysts decreased filterability while changing gas and pasting-oil content had little effect. The optimum conditions established a pasting-oil equilibrium with the best filterability. Greater degrees of hydrogenation or splitting produced more recycle middle oils but decreased filterability, thus only the necessary paste oil was produced. By selecting proper conditions, an ashfree bituminous binder could be produced, as used in the production of the Soederberg electrode. 2 tables, 2 graphs

    Hydrogen is unique among aqueous ions, both in its importance for geochemical reactions, and in its complex transport behavior through reactive media. The structure of hydrogen reaction fronts can be analyzed in the advective limit of the transport equation. At local chemical equilibrium, sorption of hydrogen onto the media surface (sorption isotherm) controls reaction front morphology. Transport modeling thus necessitates accurate knowledge of surface chemistry. Though motivated by transport, sorption models are often parameterized against batch titration experiments. The validity of these parameterizations, in a transport setting, are seldom tested. The analytic solution to the transport equation gives an algebraic relationship between concentration velocity and equilibrium sorption behavior. In this study, we conduct a suite of column flow experiments through quartz sand. Hydrogen concentration breakthrough curves at the column outlet are used to infer the "transport sorption isotherm." These results are compared to the batch titration derived sorption isotherm. We find excellent agreement between the datasets. Our findings suggest that, for aqueous hydrogen, local chemical equilibrium is a valid assumption. With the goal of a predictive transport model, we parameterize various sorption models against this dataset. Models which incorporate electrostatic effects at the surface predict transport well. Nonelectrostatic models such as the Kd, Langmuir, and Freundlich models fail. These results are particularly compelling as nonelectrostatic models are often employed to predict hydrogen transport in many reactive transport code.

    As the global need for energy increases, scientists and engineers have found a possible solution by using hydrogen to power our world. Although hydrogen can be combusted as a fuel, it is considered an energy carrier for use in fuel cells wherein it is consumed (oxidized) without the production of greenhouse gases and produces electrical energy with high efficiency. Chemical storage of hydrogen involves release of hydrogen in a controlled manner from materials in which the hydrogen is covalently bound. Sodium borohydride and aminoborane are two materials given consideration as chemical hydrogen storage materials by the US Department of Energy. A very significant barrier to adoption of these materials as hydrogen carriers is their regeneration from 'spent fuel,' i.e., the material remaining after discharge of hydrogen. The U.S. Department of Energy (DOE) formed a Center of Excellence for Chemical Hydrogen Storage, and this work stems from that project. The DOE has identified boron hydrides as being the main compounds of interest as hydrogen storage materials. The various boron hydrides are then oxidized to release their hydrogen, thereby forming a 'spent fuel' in the form of a lower boron hydride or even a boron oxide. The ultimate goal of this project is to take the oxidized boron hydrides as the spent fuel and hydrogenate them back to their original form so they can be used again as a fuel. Thus this research is essentially a boron hydride recycling project. In this report, research directed at regeneration of sodium borohydride and aminoborane is described. For sodium borohydride, electrochemical reduction of boric acid and sodium metaborate (representing spent fuel) in alkaline, aqueous solution has been investigated. Similarly to literature reports (primarily patents), a variety of cathode materials were tried in these experiments. Additionally, approaches directed at overcoming electrostatic repulsion of borate anion from the cathode, not

    This report describes the results of an effort to identify key analytic issues associated with modeling a transition to hydrogen as a fuel for light duty vehicles, and using insights gained from this effort to suggest ways to improve ongoing modeling efforts. The study reported on here examined multiple hydrogen scenarios reported in the literature, identified modeling issues associated with those scenario analyses, and examined three DOE-sponsored hydrogen transition models in the context of those modeling issues. The three hydrogen transition models are HyTrans (contractor: Oak Ridge National Laboratory), MARKAL/DOE* (Brookhaven National Laboratory), and NEMS-H2 (OnLocation, Inc). The goals of these models are (1) to help DOE improve its R&D effort by identifying key technology and other roadblocks to a transition and testing its technical program goals to determine whether they are likely to lead to the market success of hydrogen technologies, (2) to evaluate alternative policies to promote a transition, and (3) to estimate the costs and benefits of alternative pathways to hydrogen development.

    Air Products and Chemicals, Inc. has completed a comprehensive, multiyear project to demonstrate a hydrogen infrastructure in California. The specific primary objective of the project was to demonstrate a model of a real-world retail hydrogen infrastructure and acquire sufficient data within the project to assess the feasibility of achieving the nation's hydrogen infrastructure goals. The project helped to advance hydrogen station technology, including the vehicle-to-station fueling interface, through consumer experiences and feedback. By encompassing a variety of fuel cell vehicles, customer profiles and fueling experiences, this project was able to obtain a complete portrait of real market needs. The project also opened its stations to other qualified vehicle providers at the appropriate time to promote widespread use and gain even broader public understanding of a hydrogen infrastructure. The project engaged major energy companies to provide a fueling experience similar to traditional gasoline station sites to foster public acceptance of hydrogen. Work over the course of the project was focused in multiple areas. With respect to the equipment needed, technical design specifications (including both safety and operational considerations) were written, reviewed, and finalized. After finalizing individual equipment designs, complete station designs were started including process flow diagrams and systems safety reviews. Material quotes were obtained, and in some cases, depending on the project status and the lead time, equipment was placed on order and fabrication began. Consideration was given for expected vehicle usage and station capacity, standard features needed, and the ability to upgrade the station at a later date. In parallel with work on the equipment, discussions were started with various vehicle manufacturers to identify vehicle demand (short- and long-term needs). Discussions included identifying potential areas most suited for hydrogen fueling

    Based on a literature overview, this paper summarizes the impact and legacy of the contributions of Wilfried Brutsaert and Jean-Yves Parlange (Cornell University) with respect to the current state-of-the-art understanding in hydraulic groundwater theory. Forming the basis of many applications in catchment hydrology, ranging from drought flow analysis to surface water-groundwater interactions, hydraulic groundwater theory simplifies the description of water flow in unconfined riparian and perched aquifers through assumptions attributed to Dupuit and Forchheimer. Boussinesq (1877) derived a general equation to study flow dynamics of unconfined aquifers in uniformly sloping hillslopes, resulting in a remarkably accurate and applicable family of results, though often challenging to solve due to its nonlinear form. Under certain conditions, the Boussinesq equation can be solved analytically allowing compact representation of soil and geomorphological controls on unconfined aquifer storage and release dynamics. The Boussinesq equation has been extended to account for flow divergence/convergence as well as for nonuniform bedrock slope (concave/convex). The extended Boussinesq equation has been favorably compared to numerical solutions of the three-dimensional Richards equation, confirming its validity under certain geometric conditions. Analytical solutions of the linearized original and extended Boussinesq equations led to the formulation of similarity indices for baseflow recession analysis, including scaling rules, to predict the moments of baseflow response. Validation of theoretical recession parameters on real-world streamflow data is complicated due to limited measurement accuracy, changing boundary conditions, and the strong coupling between the saturated aquifer with the overlying unsaturated zone. However, recent advances are shown to have mitigated several of these issues. The extended Boussinesq equation has been successfully applied to represent baseflow

    The core in a nuclear thermal rocket will operate at high temperatures and in hydrogen. One of the important parameters in evaluating the performance of a nuclear thermal rocket is specific impulse, ISp. This quantity is proportional to the square root of the propellant’s absolute temperature and inversely proportional to square root of its molecular weight. Therefore, high temperature hydrogen is a favored propellant of nuclear thermal rocket designers. Previous work has shown that one of the life-limiting phenomena for thermal rocket nuclear cores is mass loss of fuel to flowing hydrogen at high temperatures. The hot hydrogen test facility located at the Idaho National Lab (INL) is designed to test suitability of different core materials in 2500°C hydrogen flowing at 1500 liters per minute. The facility is intended to test non-uranium containing materials and therefore is particularly suited for testing potential cladding and coating materials. In this first installment the facility is described. Automated Data acquisition, flow and temperature control, vessel compatibility with various core geometries and overall capabilities are discussed.

The analysis accounts in particular for the variation of the density and transport properties with composition. The Reynolds number of the flow R{sub j}, based on the initial jet radius a, the density {rho}{sub j} and viscosity {mu}{sub j} of the jet and the characteristic jet velocity u{sub j}, is assumed to take moderately large values, so that the jet remains slender and stable, and can be correspondingly described by numerical integration of the continuity, momentum and species conservation equations written in the boundary-layer approximation. The solution for the velocity and composition in the jet development region of planar and round jets, corresponding to streamwise distances of order R{sub j}a, is computed numerically, along with the solutions that emerge both in the near field and in the far field. The small value of the hydrogen-to-air molecular weight ratio is used to simplify the solution by considering the asymptotic limit of vanishing jet density. The development provides at leading-order explicit analytical expressions for the far-field velocity and hydrogen mass fraction that describe accurately the hydrogen jet near the axis. The information provided can be useful in particular to characterize hydrogen discharge processes from holes and cracks. (author)

  6. Hydrogen in Martian Meteorites

    Most volatile studies of Mars have targeted its surface via spacecraft and rover data, and have evidenced surficial water in polar caps and the atmosphere, in the presence of river channels, and in the detection of water bearing minerals. The other focus of Martian volatile studies has been on Martian meteorites which are all from its crust. Most of these studies are on hydrous phases like apatite, a late-stage phase, i.e. crystallizing near the end of the differentiation sequence of Martian basalts and cumulates. Moreover, calculating the water content of the magma a phosphate crystallized from is not always possible, and yet is an essential step to estimate how much water was present in a parent magma and its source. Water, however, is primarily dissolved in the interiors of differentiated planets as hydrogen in lattice defects of nominally anhydrous minerals (olivine, pyroxene, feldspar) of the crust and mantle. This hydrogen has tremendous influence, even in trace quantities, on a planet's formation, geodynamics, cooling history and the origin of its volcanism and atmosphere as well as its potential for life. Studies of hydrogen in nominally anhydrous phases of Martian meteorites are rare. Measuring water contents and hydrogen isotopes in well-characterized nominally anhydrous minerals of Martian meteorites is the goal of our study. Our work aims at deciphering what influences the distribution and origin of hydrogen in Martian minerals, such as source, differentiation, degassing and shock.

    Thin, defect-free palladium, palladium/copper and palladium/silver hydrogen absorbing membranes were microfabricated. A dual sputtering technique was used to deposit the palladium alloy membranes of only 1 {mu}m thickness on a nonporous silicon substrate. Advanced silicon etching (ASE) was applied on the backside to create a mechanically stable support structure for the thin films. Performance evaluation was carried out for different gases in a temperature range of 20 C to 298 C at a constant differential pressure of 110 kPa at the two sides of the membrane. The composite membranes show an excellent permeation rate of hydrogen, which appears to be 0.05 Pa m{sup 3} s{sup -1} and 0.01.10{sup -3} Pa m{sup 3} s{sup -1} at 20 C for the microfabricated 23 % silver and the 53 % copper composite membranes, respectively. The selectivity to hydrogen over a gas mixture containing, in addition to hydrogen, carbon monoxide, carbon dioxide and nitrogen was measured. The mass spectrometer did not detect any CO{sub 2} or CO, showing that the membrane is completely hydrogen selective. The microfabricated membranes exhibit both high mechanical strength (they easily withstand pressures up to 4 bar) and high thermal stability (up to 650 C).

    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 of 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.

    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.

    2014-07-01

    Full Text Available The present study – starting from the analysis of La glace à trois faces (A three-sided mirror, 1927 by Jean Epstein and from several theoretical writings of the same filmmaker – aims to investigate the original function that the French author recognized the camera: not at all a simple mirror of the real, but biased witness. In the film examined Epstein‟s camera rises to the observer, in the same way as it is each fictional story told, highlighting some of the essential issues of modernity: the identity based not on a membership but on a complex game of inter-individual relations and reciprocal, the uncertainty of the gaze and the reality that does not want nor can offer a definitive interpretation. Inevitable so the calls to Pirandello, first, and his conception of character on top of the person. The reflections made by Epstein will be recovered and developed by sociologists and philosophers like Erving Goffman and Christian Metz, who, on the basis of lacaniane theories, proposes in psychoanalytic key the relationship between cinema and the mirror.

    Full Text Available The narrative work of Andreï Makine (1957, a French writer of Siberian origin, is situated on the border between two geographical and cultural spaces: on the one hand the wide, wild and snowy Siberia of his childhood; on the other hand France, a mythic place which the main characters, often teenagers, of his novels look at as a model. The contrast between these two worlds is described in a particularly forceful way in one of his early novels, Au temps du fleuve Amour (1994, in which the author tells the overwhelming effect of the screening of a popular French comedy with Jean-Paul Belmondo (Le Magnifique, 1973 in a small Siberian village. Looking closely at the entire sequence which is devoted to the film in the novel, the paper aims to reconstruct the process of mythicizing the Belmondo character by the three young protagonists and to investigate the functions that the episode covers in the novel. Focusing on the different narrative levels that characterize the film plot, we show how the “phenomenon Belmondo” embodies in the novel the idea of a triple border: a geographic one (Europe/Asia, an expressive one (writing/imagine and, above all, an imaginary one (reality/fiction. We also show how this phenomenon refers, in the novel, to one of the central themes of Makine’s work: literary vocation.

    Full Text Available This article aims to demonstrate how there is a parallelism between the figurative qualities of pictorial impressionism and the avant-garde aesthetics that Jean Epstein sets in his film The Fall of the House of Usher. In turn, it is a question of studying the process of adaptation of the literary universe of Edgar Allan Poe protected in the style of Gothic romanticism, with special emphasis on visual references. For this, it is a question of investigating how descriptive appreciations are conceived that concern an avant-garde visual representation. The methodology used for the analysis is based on using the aesthetic variables that allow to support how a model of different visual representation is created. Through the analysis of the images it is possible to study the traits that characterize the ascription to the Impressionist movement and the style that defines the author brand. To this end, it is intended to describe how a suitable targeting is recreated in the staging, in which different types of environments are recreated.

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

    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.

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

    Science.gov (United States)

    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.

    Full Text Available Este artículo es un aporte teórico para la comprensión de la metáfora del lazo social. En sentido amplio, esta remite a la unión entre los individuos y a las diferentes formas que asume la identidad colectiva (“Estado”, “nación”, “pueblo”, etc. en el seno de una sociedad determinada. En las últimas décadas ha llegado a convertirse en un tropo central en el ámbito de las ciencias sociales y las humanidades, aunque sus primeras apariciones se remontan a varios siglos atrás. En el artículo nos proponemos los siguientes objetivos: por un lado, analizar comparativamente los distintos usos y significados de esta metáfora en los discursos pioneros de Jean-Jacques Rousseau y Émile Durkheim —dos autores que además de haberla utilizado con frecuencia, le asignaron un papel fundamental en sus respectivas teorías—; y por otro lado, indagar en las implicaciones más generales de esta metáfora en tres planos de análisis diferenciados: el axiológico o valorativo, el epistemológico y el ontológico.

    Full Text Available Notre-Dame des Fleurs et Miracle de la Rose sont les deux romans que Jean Genet a composés durant des périodes d’incarcération. La fiction se veut alors non seulement un remède à la solitude carcérale et à la marginalisation de son auteur, mais également un lieu de dévoilement des pratiques d’écriture propres à l’univers carcéral. Le roman tout entier se trouve dès lors habité d’une tension entre la liberté créatrice, qui fait la part belle aux provocations de l’auteur et à l’expression de ses fantasmes et un enfermement contraignant, qui pèse comme une menace sur la possibilité d’écrire.Our Lady of the Flowers and Miracle of the Rose were written during Genet’s time of imprisonment. The fictional narrative operates not only as a remedy to the experience of solitude and marginalization, but also brings the practice of prison writings into focus. The novels are haunted by a tension between a creative freedom which can launch provocations and phantasms, and the constraint of imprisonment, which threatens the very possibility of writing.

O artigo focaliza o dado obscuro da república: a esfera privada do cidadão. De acordo com a lógica interna das duas teorias, a arqueologia da vida privada começa com um conceito do político. Ambos os autores são céticos com relação à concepção moderna da vida privada como uma prioridade. Eles tendem a concordar mais com a teoria política clássica.

    Full Text Available The asymmetric unit of the title salt, C4H12N+·C8H5O4−, contains one half of a tetramethylammonium cation and one half of a hydrogen terephthalate monoanion. The N atom of the ammonium cation lies on a twofold rotation axis and the centre of mass of the terephthalate anion is on a centre of inversion. In the crystal, the centrosymmetric terephthalate ions are linked by a very short symmetric O—H...O hydrogen bond [O...O = 2.4610 (19 Å] into a one-dimensional polymeric chain along [1-12]. The tetramethylammonium cations and terephthalate anions are then connected through a pair of bifurcated acceptor C—H...O hydrogen bonds, generating a three-dimensional supramolecular network. The carboxylate groups at both ends of the terephthalate anion are charge-shared with an equal probability of 0.5.

    Hydrogen fueling stations are an essential element in the practical application of hydrogen as a vehicle fuel, and a number of issues such as safety, efficiency, design, and operating procedures can only be accurately addressed by a practical demonstration. Regardless of whether the vehicle is powered by an internal combustion engine or fuel cell, or whether the vehicle has a liquid or gaseous fuel tank, the fueling station is a critical technology which is the link between the local storage facility and the vehicle. Because most merchant hydrogen delivered in the US today (and in the near future) is in liquid form due to the overall economics of production and delivery, we believe a practical refueling station should be designed to receive liquid. Systems studies confirm this assumption for stations fueling up to about 300 vehicles. Our fueling station, aimed at refueling fleet vehicles, will receive hydrogen as a liquid and dispense it as either liquid, high pressure gas, or low pressure gas. Thus, it can refuel any of the three types of tanks proposed for hydrogen-powered vehicles -- liquid, gaseous, or hydride. The paper discusses the fueling station design. Results of a numerical model of liquid hydrogen vehicle tank filling, with emphasis on no vent filling, are presented to illustrate the usefulness of the model as a design tool. Results of our vehicle performance model illustrate our thesis that it is too early to judge what the preferred method of on-board vehicle fuel storage will be in practice -- thus our decision to accommodate all three methods.

    As our dependence on foreign oil increases and concerns about global climate change rise, the need to develop sustainable energy technologies is becoming increasingly significant. Worldwide energy consumption is expected to double by the year 2050, as will carbon emissions along with it. This increase in emissions is a product of an ever-increasing demand for energy, and a corresponding rise in the combustion of carbon containing fossil fuels such as coal, petroleum, and natural gas. Undisputable scientific evidence indicates significant changes in the global climate have occurred in recent years. Impacts of climate change and the resulting atmospheric warming are extensive, and know no political or geographic boundaries. These far-reaching effects will be manifested as environmental, economic, socioeconomic, and geopolitical issues. Offsetting the projected increase in fossil energy use with renewable energy production will require large increases in renewable energy systems, as well as the ability to store and transport clean domestic fuels. Storage and transport of electricity generated from intermittent resources such as wind and solar is central to the widespread use of renewable energy technologies. Hydrogen created from water electrolysis is an option for energy storage and transport, and represents a pollution-free source of fuel when generated using renewable electricity. The conversion of chemical to electrical energy using fuel cells provides a high efficiency, carbon-free power source. Hydrogen serves to blur the line between stationary and mobile power applications, as it can be used as both a transportation fuel and for stationary electricity generation, with the possibility of a distributed generation energy infrastructure. Hydrogen and fuel cell technologies will be presented as possible pollution-free solutions to present and future energy concerns.

    The present invention is directed to a method of screening microbe strains capable of generating hydrogen. This method involves inoculating one or more microbes in a sample containing cell culture medium to form an inoculated culture medium. The inoculated culture medium is then incubated under hydrogen producing conditions. Once incubating causes the inoculated culture medium to produce hydrogen, microbes in the culture medium are identified as candidate microbe strains capable of generating hydrogen. Methods of producing hydrogen using one or more of the microbial strains identified as well as the hydrogen producing strains themselves are also disclosed.

    Polyhydride metal complexes are being developed for application in hydrogen storage. Efforts have focused on developing complexes with improved available hydrogen weight percentages. We have explored the possibility that complexes containing aromatic hydrocarbon ligands could store hydrogen at both the metal center and in the ligands. We have synthesized novel indenyl hydride complexes and explored their reactivity with hydrogen. The reversible hydrogenation of [IrH{sub 3}(PPh{sub 3})({eta}{sup 5}-C{sub 10}H{sub 7})]{sup +} has been achieved. While attempting to prepare {eta}{sup 6}-tetrahydronaphthalene complexes, we discovered that certain polyhydride complexes catalyze both the hydrogenation and dehydrogenation of tetrahydronaphthalene.

Thus, research on designing new, inexpensive, and abundant HER catalysts is important. Here, we describe how a simple experiment....... The curve visually shows students that the best HER catalysts are characterized by an optimal hydrogen binding energy (reactivity), as stated by the Sabatier principle. In addition, students may use this volcano curve to predict the activity of an untested catalyst solely from the catalyst reactivity...

    O objetivo deste artigo é introduzir o leitor no pensamento político de Jean-Jacques Rousseau, com base nas reflexões do autor em Do contrato social. Partindo-se da distinção entre poder e autoridade, procura-se mostrar o fundamento da legitimidade e a construção do contrato social ideal. Para o filósofo genebrino, a soberania, entendida como a vontade geral em ação, constitui o fundamento mais adequado às repúblicas, regidas por leis emanadas da vontade geral, as únicas capazes de expressar os interesses gerais de um “eu comum” que não se confunde nem com a maioria nem com os particulares. Depois de apresentadas as características centrais do poder soberano, discute-se o papel do governo e da religião civil na vida politicamente organizada sob um Estado republicano.

  16. Liquid Organic Hydrogen Carriers (LOHCs): Toward a Hydrogen-free Hydrogen Economy.

    Science.gov (United States)

    Preuster, Patrick; Papp, Christian; Wasserscheid, Peter

    2017-01-17

    The need to drastically reduce CO 2 emissions will lead to the transformation of our current, carbon-based energy system to a more sustainable, renewable-based one. In this process, hydrogen will gain increasing importance as secondary energy vector. Energy storage requirements on the TWh scale (to bridge extended times of low wind and sun harvest) and global logistics of renewable energy equivalents will create additional driving forces toward a future hydrogen economy. However, the nature of hydrogen requires dedicated infrastructures, and this has prevented so far the introduction of elemental hydrogen into the energy sector to a large extent. Recent scientific and technological progress in handling hydrogen in chemically bound form as liquid organic hydrogen carrier (LOHC) supports the technological vision that a future hydrogen economy may work without handling large amounts of elemental hydrogen. LOHC systems are composed of pairs of hydrogen-lean and hydrogen-rich organic compounds that store hydrogen by repeated catalytic hydrogenation and dehydrogenation cycles. While hydrogen handling in the form of LOHCs allows for using the existing infrastructure for fuels, it also builds on the existing public confidence in dealing with liquid energy carriers. In contrast to hydrogen storage by hydrogenation of gases, such as CO 2 or N 2 , hydrogen release from LOHC systems produces pure hydrogen after condensation of the high-boiling carrier compounds. This Account highlights the current state-of-the-art in hydrogen storage using LOHC systems. It first introduces fundamental aspects of a future hydrogen economy and derives therefrom requirements for suitable LOHC compounds. Molecular structures that have been successfully applied in the literature are presented, and their property profiles are discussed. Fundamental and applied aspects of the involved hydrogenation and dehydrogenation catalysis are discussed, characteristic differences for the catalytic conversion of

  20. Hydrogen storage for automobiles

    Strickland, G.

    1979-01-01

    Results of an analysis of hydrogen-fueled automobiles are presented as a part of a continuing study conducted by Lawrence Livermore Laboratory (LLL) on Energy Storage Systems for Automobile Propulsion. The hydrogen is stored either as a metal hydride at moderate pressure in TiFe/sub 0/ /sub 9/Mn/sub 0/ /sub 1/H/sub x/ and at low pressure in MgH/sub x/ catalyzed with 10 wt % Ni, or it is stored in hollow glass microspheres at pressures up to about 400 atm. Improved projections are given for the two hydrides, which are used in combination to take advantage of their complementary properties. In the dual-hydride case and in the microsphere case where Ti-based hydride is used for initial operation, hydrogen is consumed in an internal-combustion engine; whereas in the third case, hydrogen from Ti-based hydride is used with air in an alkaline fuel cell/Ni-Zn battery combination which powers an electric vehicle. Each system is briefly described; and the results of the vehicle analysis are compared with those for the conventional automobile and with electric vehicles powered by Pb-acid or Ni-Zn batteries. Comparisons are made on the basis of automobile weight, initial user cost, and life-cycle cost. In this report, the results are limited to those for the 5-passenger vehicle in the period 1985-1990, and are provided as probable and optimistic values.

Development of production costs for liquid products is indicated for the years 1927-1941. Data on test costs are also given. Production figures for hydrogenation are shown, as well as the share of Farben synthetics in total German fuel production. The report gives a breakdown for requirements of raw materials, manpower, capital, and construction steels for production of four million metric tons of fuels from hydrogenation. Finally, the report lists the special areas in which Farben was carrying on work related to synthetic fuels. The data are given mostly in tabular form.

  2. Hydrogen escape from Mars enhanced by deep convection in dust storms

    Present-day water loss from Mars provides insight into Mars's past habitability1-3. Its main mechanism is thought to be Jeans escape of a steady hydrogen reservoir sourced from odd-oxygen reactions with near-surface water vapour2, 4,5. The observed escape rate, however, is strongly variable and correlates poorly with solar extreme-ultraviolet radiation flux6-8, which was predicted to modulate escape9. This variability has recently been attributed to hydrogen sourced from photolysed middle atmospheric water vapour10, whose vertical and seasonal distribution is only partly characterized and understood11-13. Here, we report multi-annual observational estimates of water content and dust and water transport to the middle atmosphere from Mars Climate Sounder data. We provide strong evidence that the transport of water vapour and ice to the middle atmosphere by deep convection in Martian dust storms can enhance hydrogen escape. Planet-encircling dust storms can raise the effective hygropause (where water content rapidly decreases to effectively zero) from 50 to 80 km above the areoid (the reference equipotential surface). Smaller dust storms contribute to an annual mode in water content at 40-50 km that may explain seasonal variability in escape. Our results imply that Martian atmospheric chemistry and evolution can be strongly affected by the meteorology of the lower and middle atmosphere of Mars.

  4. Onboard hydrogen generation for automobiles

    Houseman, J.; Cerini, D. J.

    1976-01-01

    Problems concerning the use of hydrogen as a fuel for motor vehicles are related to the storage of the hydrogen onboard a vehicle. The feasibility is investigated to use an approach based on onboard hydrogen generation as a means to avoid these storage difficulties. Two major chemical processes can be used to produce hydrogen from liquid hydrocarbons and methanol. In steam reforming, the fuel reacts with water on a catalytic surface to produce a mixture of hydrogen and carbon monoxide. In partial oxidation, the fuel reacts with air, either on a catalytic surface or in a flame front, to yield a mixture of hydrogen and carbon monoxide. There are many trade-offs in onboard hydrogen generation, both in the choice of fuels as well as in the choice of a chemical process. Attention is given to these alternatives, the results of some experimental work in this area, and the combustion of various hydrogen-rich gases in an internal combustion engine.

  5. Biomimetic Production of Hydrogen

    Science.gov (United States)

    Gust, Devens

    2004-03-01

    The basic reaction for hydrogen generation is formation of molecular hydrogen from two electrons and two protons. Although there are many possible sources for the protons and electrons, and a variety of mechanisms for providing the requisite energy for hydrogen synthesis, the most abundant and readily available source of protons and electrons is water, and the most attractive source of energy for powering the process is sunlight. Not surprisingly, living systems have evolved to take advantage of these sources for materials and energy. Thus, biology provides paradigms for carrying out the reactions necessary for hydrogen production. Photosynthesis in green plants uses sunlight as the source of energy for the oxidation of water to give molecular oxygen, protons, and reduction potential. Some photosynthetic organisms are capable of using this reduction potential, in the form of the reduced redox protein ferredoxin, to reduce protons and produce molecular hydrogen via the action of an hydrogenase enzyme. A variety of other organisms metabolize the reduced carbon compounds that are ultimately the major products of photosynthesis to produce molecular hydrogen. These facts suggest that it might be possible to use light energy to make molecular hydrogen via biomimetic constructs that employ principles similar to those used by natural organisms, or perhaps with hybrid "bionic" systems that combine biomimetic materials with natural enzymes. It is now possible to construct artificial photosynthetic systems that mimic some of the major steps in the natural process.(1) Artificial antennas based on porphyrins, carotenoids and other chromophores absorb light at various wavelengths in the solar spectrum and transfer the harvested excitation energy to artificial photosynthetic reaction centers.(2) In these centers, photoinduced electron transfer uses the energy from light to move an electron from a donor to an acceptor moiety, generating a high-energy charge-separated state

  6. Detroit Commuter Hydrogen Project

    2010-07-31

    This project was undertaken to demonstrate the viability of using hydrogen as a fuel in an internal combustion engine vehicle for use as a part of a mass transit system. The advantages of hydrogen as a fuel include renew-ability, minimal environmental impact on air quality and the environment, and potential to reduce dependence on foreign energy sources for the transportation sector. Recognizing the potential for the hydrogen fuel concept, the Southeast Michigan Congress of Governments (SEMCOG) determined to consider it in the study of a proposed regional mass transit rail system for southeast Michigan. SEMCOG wanted to evaluate the feasibility of using hydrogen fueled internal combustion engine (H2ICE) vehicles in shuttle buses to connect the Detroit Metro Airport to a proposed, nearby rail station. Shuttle buses are in current use on the airport for passenger parking and inter-terminal transport. This duty cycle is well suited to the application of hydrogen fuel at this time because of the ability to re-fuel vehicles at a single nearby facility, overcoming the challenge of restricted fuel availability in the undeveloped hydrogen fuel infrastructure. A cooperative agreement between SEMCOG and the DOE was initiated and two H2ICE buses were placed in regular passenger service on March 29, 2009 and operated for six months in regular passenger service. The buses were developed and built by the Ford Motor Company. Wayne County Airport Authority provided the location for the demonstration with the airport transportation contractor, Metro Cars Inc. operating the buses. The buses were built on Ford E450 chassis and incorporated a modified a 6.8L V-10 engine with specially designed supercharger, fuel rails and injectors among other sophisticated control systems. Up to 30 kg of on-board gaseous hydrogen were stored in a modular six tank, 350 bar (5000 psi) system to provide a 150 mile driving range. The bus chassis and body were configured to carry nine passengers with

    1996-10-01

    This is a new project, which started in June 1995, and involves photovoltaic hydrogen production as a fuel production method for the future. In order to increase the hydrogen yield, it was decided to use hybrid solar collectors to generate D.C. electricity, as well as high temperature steam for input to the electrolyzer. In this way, some of the energy needed to dissociate the water is supplied in the form of heat (or low grade energy), to generate steam, which results in a reduction of electrical energy (or high grade energy) needed. As a result, solar to hydrogen conversion efficiency is increased. In the above stated system, the collector location, the collector tracking sub-system (i.e., orientation/rotation), and the steam temperature have been taken as variables. Five locations selected - in order to consider a variety of latitudes, altitudes, cloud coverage and atmospheric conditions - are Atlanta, Denver, Miami, Phoenix and Salt Lake City. Plain PV and hybrid solar collectors for a stationary south facing system and five different collector rotation systems have been analyzed. Steam temperatures have been varied between 200{degrees}C and 1200{degrees}C. During the first year, solar to hydrogen conversion efficiencies have been considered. The results show that higher steam temperatures, 2 dimensional tracking system, higher elevations and dryer climates causes higher conversion efficiencies. Cost effectiveness of the sub-systems and of the overall system will be analyzed during the second year. Also, initial studies will be made of an advanced high efficiency hybrid solar hydrogen production system.

    This report covers two topics. The first is a review of codes, standards, regulations, recommendations, certifications, and pamphlets which address safety of gaseous fuels. The second is an experimental investigation of hydrogen flame impingement. Four areas of concern in the conversion of natural gas safety publications to hydrogen safety publications are delineated. Two suggested design criteria for hydrogen vehicle fuel systems are proposed. It is concluded from the experimental work that light weight, low cost, firewalls to resist hydrogen flame impingement are feasible.

    The detection of hydrogen fires is important to the aerospace community. The National Aeronautics and Space Administration (NASA) has devoted significant effort to the development, testing, and installation of hydrogen fire detectors based on ultraviolet, near-infrared, mid-infrared, andor far-infrared flame emission bands. Yet, there is no intensity calibrated hydrogen-air flame spectrum over this range in the literature and consequently, it can be difficult to compare the merits of different radiation-based hydrogen fire detectors.

    Muonic hydrogen participates in many different interactions, including muon induced fusion of hydrogen nuclei. Conventional experimental techniques cannot always unravel and separate the processes of interest. Some of the most important measurements may be more reliably accomplished with the use of a unique and versatile target consisting of layers of different solid hydrogen isotope mixtures. {copyright} {ital 1998 American Institute of Physics.}

    Full Text Available Jean Stafford’s short story “The Interior Castle” (1946 and Sylvia Plath’s “Face Lift” and “The Plaster”, written in the early 1960s but published posthumously in Crossing the Water (1971, dwell on a theme which is rarely tackled in Postwar American literature: plastic surgery. Using a markedly mnemonic tone, both authors trace in detail the passive submission of female bodies to male (reconstruction. While the history of women in early Cold War America is usually associated with the patriarchal mystifying of housewifery, the myth of ideal, domestic femininity was also intimately related to bodily beauty. The demand for physical “perfection” which resulted from constructing women as, primarily, objects of male desire was mirrored in popular magazines, such as Ladies’ Home Journal, which endorsed women’s seeking medical aid to model themselves into “ideal” sexual mates (Meyerowitz in Meyerowitz ed., 244. Women’s submission to the notion that they should use any means necessary to become aesthetic objects to be appraised by men was thus represented as desirable. In this paper, I shall trace how both Stafford and Plath adopted a confessional style of writing in the abovementioned pieces in order to denounce the cultural construction of women as passive bodies to be moulded at will, instead of as active, thinking subjects. I shall argue that by reproducing the recollections and thoughts of the women being stitched, sewn and bandaged in their pieces, both authors articulated an alternative protofeminist aesthetics based on the beauty of what Stafford described as “inscrutable intelligence”.

    Full Text Available Hantée par le retrait du divin, la poésie de Jean Grosjean chante la perte du dieu et la solitude du sujet. Trois recueils, séparés de plus de trente ans, nous permettent d’examiner les modalités variées de la plainte élégiaque, depuis la grande déploration oratoire jusqu’à un murmure proche du silence, et les figures du sujet lyrique dont elle construit l’image. Dans Apocalypse (1962, s’élève la voix du Créateur qui pleure la perte de son fils, voué à l’aliénation et à la mort par sa venue au monde, lamento auquel répond celui du Christ en croix, puis celui du fidèle abandonné dont la parole vise à conjurer l’absence. Élégies (1967 renvoie à la posture plus classique du deuil, où le sujet lyrique déplore la perte de la femme passionnément aimée, mais l’énonciation ébauche à l’arrière-plan une perte plus radicale, celle du divin. Dans Nathanaël enfin (1995, le sujet semble s’effacer devant la contemplation quasi muette du monde, d’une nature d’où Dieu s’est absenté, en proie au vertige du mouvement et du temps, et l’énoncé souvent impersonnel dessine en creux l’image d’un sage, entre résignation et acquiescement.

  17. Hydrogen attack - Influence of hydrogen sulfide. [on carbon steel

    1978-01-01

    An experimental study is conducted on 12.5-mm-thick SAE 1020 steel (plain carbon steel) plate to assess hydrogen attack at room temperature after specimen exposure at 525 C to hydrogen and a blend of hydrogen sulfide and hydrogen at a pressure of 3.5 MN/sq m for exposure times up to 240 hr. The results are discussed in terms of tensile properties, fissure formation, and surface scales. It is shown that hydrogen attack from a high-purity hydrogen environment is severe, with the formation of numerous methane fissures and bubbles along with a significant reduction in the room-temperature tensile yield and ultimate strengths. However, no hydrogen attack is observed in the hydrogen/hydrogen sulfide blend environment, i.e. no fissure or bubble formation occurred and the room-temperature tensile properties remained unchanged. It is suggested that the observed porous discontinuous scale of FeS acts as a barrier to hydrogen entry, thus reducing its effective equilibrium solubility in the iron lattice. Therefore, hydrogen attack should not occur in pressure-vessel steels used in many coal gasification processes.

    Two-electron reduction of oxygen to produce hydrogen peroxide is a much researched topic. Most of the work has been done in the production of hydrogen peroxide in basic media, in order to address the needs of the pulp and paper industry. However, peroxides under alkaline conditions show poor stabilities and are not useful in disinfection applications. There is a need to design electrocatalysts that are stable and provide good current and energy efficiencies to produce hydrogen peroxide under acidic conditions. The innovation focuses on the in situ generation of hydrogen peroxide using an electrochemical cell having a gas diffusion electrode as the cathode (electrode connected to the negative pole of the power supply) and a platinized titanium anode. The cathode and anode compartments are separated by a readily available cation-exchange membrane (Nafion 117). The anode compartment is fed with deionized water. Generation of oxygen is the anode reaction. Protons from the anode compartment are transferred across the cation-exchange membrane to the cathode compartment by electrostatic attraction towards the negatively charged electrode. The cathode compartment is fed with oxygen. Here, hydrogen peroxide is generated by the reduction of oxygen. Water may also be generated in the cathode. A small amount of water is also transported across the membrane along with hydrated protons transported across the membrane. Generally, each proton is hydrated with 3-5 molecules. The process is unique because hydrogen peroxide is formed as a high-purity aqueous solution. Since there are no hazardous chemicals or liquids used in the process, the disinfection product can be applied directly to water, before entering a water filtration unit to disinfect the incoming water and to prevent the build up of heterotrophic bacteria, for example, in carbon based filters. The competitive advantages of this process are: 1. No consumable chemicals are needed in the process. The only raw materials

    Measurements of thermal desorption and electron work function were used to investigate the mechanism of hydrogen adsorption from the gas phase on rhodium single-crystal faces and on a polycrystalline rhodium sample at room temperatures over the pressure range from 1.3-10/sup -3/ to 1.3 x 10/sup -5/ Pa. It was found that dipoles oriented with their negative ends toward the gas phase (dipoles of type I) form more rapidly than dipoles having the opposite orientation (dipoles of type II). For formation of the latter, a mechanism is proposed according to which the rate-determining step of the overall process is the transition of reversibly adsorbed hydrogen to dipoles of type II (the spillover), which occurs at surface defects. It was shown that the kinetics of this process with respect to the individual defect obeys an equation which is zeroth order in theta/sub H/ and pressure.

    Full Text Available As a result of international agreements on the reduction of CO2 emissions, new technologies using hydrogen are being developed. Hydrogen, despite being the most abundant element in Nature, cannot be found in its pure state. Water is one of the most abundant sources of hydrogen on the planet. The proposal here is to use energy from the sea in order to obtain hydrogen from water. If plants to obtain hydrogen were to be placed in the ocean, the impact of long submarines piping to the coast will be reduced.

    The coal liquefaction process disclosed uses three stages. The first stage is a liquefaction. The second and third stages are hydrogenation stages at different temperatures and in parallel or in series. One stage is within 650.degree.-795.degree. F. and optimizes solvent production. The other stage is within 800.degree.-840.degree. F. and optimizes the C.sub.5 -850.degree. F. product.

    The electron-transport system of cell-free extracts obtained from Hydrogenomonas H-20 has been studied with particular reference to phosphorylation associated with the oxyhydrogen reaction. Cell-free preparations of this organism exhibit oxidative phosphorylation with hydrogen and succinate as electron donors. This activity could be uncoupled with a number of agents. Ratios of phosphorylative activity to oxidative activity observed varied from 0.2 to 0.7. Factors affecting the efficiency of phosphorylation were examined. Inhibitor and spectrophotometric studies indicated that phosphorylation with hydrogen as electron donor occurs exclusively at a site in an abbreviated electron transport chain between H(2) and cytochrome b. The possible occurrence of a cytochrome b oxidase and the requirement for a quinone are discussed, as well as the correlation between the abbreviated pathway and the energy generation by the cell. Evidence is presented which indicates that nicotinamide adenine dinucleotide does not participate in the hydrogen oxidation path which is coupled to adenosine triphosphate formation.

    The large-scale production of hydrogen utilizing energy provided by a renewable source to split water is one of the most ambitious long-term goals of the U.S. Department of Energy`s Hydrogen Program. Photoelectrochemical devices-direct photoconversion systems utilizing a photovoltaic-type structure coated with water-splitting catalysts-represent a promising option to meet this goal. Direct solar-to-chemical conversion efficiencies greater than 7% and photoelectrode lifetimes of up to 30 hours in 1 molar KOH have been demonstrated in our laboratory using low-cost, amorphous-silicon-based photoelectrodes. Loss analysis models indicate that the DOE`s goal of 10% solar-to-chemical conversion can be met with amorphous-silicon-based structures optimized for hydrogen production. In this report, we describe recent progress in the development of thin-film catalytic/protective coatings, improvements in photoelectrode efficiency and stability, and designs for higher efficiency and greater stability.

    Full Text Available Chitosan and Trametes versicolor were used as the material for processing liquid waste product from the jeans washing industry in this study as they were more economics and no negative damage in the environmental life. This research is to find out the chitosan and Trametes versicolor effect as the coagulant in decreasing the colour and the COD content of the liquid waste product from the jeans washing industry using the coagulation method and floculation. The dosage of chitosan and Trametes versicolor were 200, 400, 600, 800 and 1000 mg/L of the liquid waste product whereas the combination of chitosan and Trametes versicolor were 4:1, 3:2, 2:3 and 1:4. The data resulted from the analysis were shown as a graphics. The research results show that the optimum dosage of chitosan as coagulant was 800 mg/L which was able to decrease the colour intensity. For blue colour, the intensity decreased from 1.2 to 0.1%; the yellow colour intensity decreased from 0.9 to 0.0% and the COD 91.23%. The optimum dosage of Trametes versicolor of 600 mg/L was able to decrease the blue colour intensity from 1.2 to 0.11%; the yellow colour intensity from 0.9 to 0.1% and the COD was 91.37%. By using the combinationof chitosan and Trametes versicolor it was shown that the best result was using the 3:2 ratio which was able to decrease the blue colour intensity from 0.9 to 0.1% and the yellow colour intensity from 0.9 to 0.0% and the COD was 86.68%.   Keywords: colour intensity, COD, liquid waste product of the jeans washing, chitosan, Trametes versicolor

    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.

    The results of a study to evaluate the use of RADARSAT images for the period following the progress of the 1997 spring ice breakup on several hydro-electric reservoirs of the Saguenay - Lac Saint-Jean region were presented. Following the catastrophic floods of 1996, the remote sensing laboratory of the Universite du Quebec at Chicoutimi acquired six RADARSAT images of the Saguenay - Lac Saint-Jean region. Three of the images were in high-resolution mode, the others were in wide-angle mode. The images were used to evaluate the evolution of the spring ice breakup on the region`s numerous hydro-electric reservoirs, in particular the Lac Saint-Jean, Kenogami, Pipmuacan and Manouane reservoirs. Image filtering and compression methods were described. The results indicate that ice breakup which starts first in the west of the region, occurs initially at the mouths of rivers, followed by the beds of ancient rivers. Multi-date images show very high potential for evaluating and monitoring spring breakup.

    The Chemical Industry consumes large volumes of hydrogen as raw material for the manufacture of numerous products (e.g. polyamides and polyurethanes account for 60% of hydrogen demand). The hydrogen demand was in the recent past and will continue to be driven by the polyurethane family. China will host about 60% of new hydrogen needs over the period 2010-2015 becoming the first hydrogen market next year and reaching 25% of market share by 2015 (vs. only 4% in 2001). Air Liquide supplies large volumes of Hydrogen (and other Industrial Gases) to customers by on-site plants and through pipeline networks which offer significant benefits such as higher safety, reliability and flexibility of supply. Thanks to its long term strategy and heavy investment in large units and pipeline networks, Air Liquide is the Industrial Gas leader in most of the world class Petrochemical basins (Rotterdam, Antwerp, US Gulf Coast, Yosu, Caojing,..)

    1943-05-03

    Processes serving as producers of slightly hydrogenated coal are discussed. It was established that the working process of an extracting hydrogenation from coal alone did not present optimal conditions for production of slightly hydrogenated coal, and therefore led to unfavorably high costs. More favorable operating costs were expected with the use of larger amounts of gas or with simultaneous production of asphalt-free oils in larger quantity. The addition of coal into the hydrogenation of low temperature carbonization tars made it possible to produce additional briquetting material (slightly hydrogenated coal) in the same reaction space without impairment of the tar hydrogenation. This was to lower the cost still more. For reasons of heat exchange, the process with a cold separator was unfavorable, and consideration of the residue quality made it necessary to investigate how high the separator temperature could be raised. 3 tables.

    Energy Technology Data Exchange (ETDEWEB)

    Roser, R. [NRG Technologies, Inc., Reno, NV (United States)

    1998-08-01

    NRG Technologies, Inc. is attempting to develop hardware and infrastructure that will allow mixtures of hydrogen and conventional fuels to become viable alternatives to conventional fuels alone. This commercialization can be successful if the authors are able to achieve exhaust emission levels of less than 0.03 g/kw-hr NOx and CO; and 0.15 g/kw-hr NMHC at full engine power without the use of exhaust catalysts. The major barriers to achieving these goals are that the lean burn regimes required to meet exhaust emissions goals reduce engine output substantially and tend to exhibit higher-than-normal total hydrocarbon emissions. Also, hydrogen addition to conventional fuels increases fuel cost, and reduces both vehicle range and engine output power. Maintaining low emissions during transient driving cycles has not been demonstrated. A three year test plan has been developed to perform the investigations into the issues described above. During this initial year of funding research has progressed in the following areas: (a) a cost effective single-cylinder research platform was constructed; (b) exhaust gas speciation was performed to characterize the nature of hydrocarbon emissions from hydrogen-enriched natural gas fuels; (c) three H{sub 2}/CH{sub 4} fuel compositions were analyzed using spark timing and equivalence ratio sweeping procedures and finally; (d) a full size pick-up truck platform was converted to run on HCNG fuels. The testing performed in year one of the three year plan represents a baseline from which to assess options for overcoming the stated barriers to success.

    Hydrogen, produced using renewable resources, is an environmentally benign energy carrier that will play a vital role in sustainable energy systems. The US Department of Energy (DOE) supports the development of cost-effective technologies for hydrogen production, storage, and utilization to facilitate the introduction of hydrogen in the energy infrastructure. International interest in hydrogen as an energy carrier is high. Research, development, and demonstration (RD and D) of hydrogen energy systems are in progress in many countries. Annex 11 of the International Energy Agency (IEA) facilitates member countries to collaborate on hydrogen RD and D projects. The United States is a member of Annex 11, and the US representative is the Program Manager of the DOE Hydrogen R and D Program. The Executive Committee of the Hydrogen Implementing Agreement in its June 1997 meeting decided to review the production costs of hydrogen via the currently commercially available processes. This report compiles that data. The methods of production are steam reforming, partial oxidation, gasification, pyrolysis, electrolysis, photochemical, photobiological, and photoelectrochemical reactions.

    The article gives a comprehensive overview of hydrogen storage in carbon nanostructures, including experimental results and theoretical calculations. Soon after the discovery of carbon nanotubes in 1991, different research groups succeeded in filling carbon nanotubes with some elements, and, therefore, the question arose of filling carbon nanotubes with hydrogen by possibly using new effects such as nano-capillarity. Subsequently, very promising experiments claiming high hydrogen storage capacities in different carbon nanostructures initiated enormous research activity. Hydrogen storage capacities have been reported that exceed the benchmark for automotive application of 6.5 wt% set by the U.S. Department of Energy. However, the experimental data obtained with different methods for various carbon nanostructures show an extreme scatter. Classical calculations based on physisorption of hydrogen molecules could not explain the high storage capacities measured at ambient temperature, and, assuming chemisorption of hydrogen atoms, hydrogen release requires temperatures too high for technical applications. Up to now, only a few calculations and experiments indicate the possibility of an intermediate binding energy. Recently, serious doubt has arisen in relation to several key experiments, causing considerable controversy. Furthermore, high hydrogen storage capacities measured for carbon nanofibers did not survive cross-checking in different laboratories. Therefore, in light of today's knowledge, it is becoming less likely that at moderate pressures around room temperature carbon nanostructures can store the amount of hydrogen required for automotive applications.

    The purpose of the present randomized trial was to compare the Jean Rives (JR) technique and the laparoscopic totally extraperitoneal (TEP) repair for the treatment of primary inguinal hernias with respect to operating time, hospital stay, sick leave, chronic pain and recurrences after a follow-up of 10 years. 110 patients with primary inguinal hernia were randomized to either a JR repair (53 patients) or to a laparoscopic (TEP) repair (57 patients). All the interventions were exclusively realized by two experienced surgeons. Follow-up examinations were performed after 1, 6 months, 1, 5 and 10 years. Both groups were identical concerning age and hernia type, which were type II and type IIIa according to Nyhus classification. No significant difference was found concerning hospital stay, chronic pain and recurrences. The operating time was significantly lower in JR group, whereas the sick leave was significantly in favor of TEP group. Jean Rives technique is a relatively easy technique to perform, requires shorter operating time when compared to laparoscopic TEP technique. JR technique should be taken into consideration while planning surgical treatment of inguinal hernia.

    Gaier, Claude

    1983-12-01

    Full Text Available JEAN d'Outremeuse fut et reste le plus populaire des vieux auteurs qui ont écrit l'histoire de l'ancienne principauté de Liège. Cette notoriété, il la doit sans doute à l'usage de la langue vulgaire -un français teinté de wallon- et aussi à l'extraordinaire profusion de détails pitttoresques qui émaillent ses narrations, où vingt générations d'érudits, de littérateurs et d'échotiers du passé ont puisé leur inspiration. Pourtant, la critique historique de notre siècle n'a eu aucune peine à démontrer que pareil ascendant n'était pas mérité, puisque Jean d'Outremeuse avait bel et bien recopié d'autres récits ou inventé de toutes pièces la matière qu'il n'avait pas trouvée dans des sources antérieures. De sorte que, à quelques nuances près, l'admiration sans bornes qu'on lui vouait jadis à désormais cédé la place au scepticisme, voire au dénigrement systématique à son égard.

    The first test facility was built in Ludwigshafen in Building 35 in 1924. During the Technical Committee meeting of February 4, 1926, Carl Bosch reported briefly for the first time on the status of coal hydrogenation and promised a comprehensive report to follow. Next, in connection with the Technical Committee meeting of July 13, 1926, Bosch arranged for the Committee to tour the test facility. Subsequently, the first industrial facility, for a yearly output of 100,000 tons, was built in Leuna with great speed and began production in April 1927. For this facility RM 26.6 million in credit was appropriated during 1926 and 1927 (the costs, including associated units, were estimated at RM 46 million; the RM 26.6 million covered only erection of the plant). A further RM 264 million was written off to hydrogenation in the years 1926 to 1931 on tests in new areas. At the end of 1929 the large scale tests at Merseburg were interrupted. On April 7, 1932, in the Nitrogen Branch discussion at Ludwigshafen, Dr. Schneider reported on the improvement in coal decomposition percentage which had meanwhile been achieved: from 60% to 95%. He proposed a last large-scale test, which was to require RM 375,000 up to the starting point and RM 170,000 per month during the six-month test period. This last test then led to definitive success in 1933.

  4. Novel developments in hydrogen storage, hydrogen activation and ionic liquids

    2010-12-03

    This dissertation is divided into three chapters. Recently, metal-free hydrogen activation using phosphorous compounds has been reported in science magazine. We have investigated the interaction between hydrogen and phosphorous compounds in presence of strong Lewis acids (chapter one). A new generation of metal-free hydrogen activation, using amines and strong Lewis acids with sterically demanding nature, was already developed in our group. Shortage of high storage capacity using large substitution to improve sterical effect led us to explore the amine borane derivatives, which are explained in chapter two. Due to the high storage capacity of hydrogen in aminoborane derivatives, we have explored these materials to extend hydrogen release. These compounds store hydrogen as proton and hydride on adjacent atoms or ions. These investigations resulted in developing hydrogen storage based on ionic liquids containing methyl guanidinium cation. Then we have continued to develop ionic liquids based on methyl guanidinium cation with different anions, such as tetrafluoro borate (chapter three). We have replaced these anions with transition metal anions to investigate hydrogen bonding and catalytic activity of ionic liquids. This chapter illustrates the world of ionic liquid as a green solvent for organic, inorganic and catalytic reactions and combines the concept of catalysts and solvents based on ionic liquids. The catalytic activity is investigated particularly with respect to the interaction with CO{sub 2}. (orig.)

    Hydrogen technologies are maturing at rapid speed, something we experience in Norway and around the globe every day as demonstration projects for vehicles and infrastructure expand at a rate unthinkable of only a few years ago. An example of this evolution happened in Norway in 2009 when two hydrogen filling stations were opened on May the 11th, making it possible to arrange the highly successful Viking Rally from Oslo to Stavanger with more than 40 competing teams. The Viking Rally demonstrated for the public that battery and hydrogen-electric vehicles are technologies that exist today and provide a real alternative for zero emission mobility in the future. The driving range of the generation of vehicles put into demonstration today is more than 450 km on a full hydrogen tank, comparable to conventional vehicles. As the car industry develops the next generation of vehicles for serial production within the next 4-5 years, we will see vehicles that are more robust, more reliable and cost effective. Also on the hydrogen production and distribution side progress is being made, and since renewable hydrogen from biomass and electrolysis is capable of making mobility basically emission free, hydrogen can be a key component in combating climate change and reducing local emissions. The research Council of Norway has for many years supported the development of hydrogen and fuel cell technologies, and The Research Council firmly believes that hydrogen and fuel cell technologies play a crucial role in the energy system of the future. Hydrogen is a flexible transportation fuel, and offers possibilities for storing and balancing intermittent electricity in the energy system. Norwegian companies, research organisations and universities have during the last decade developed strong capabilities in hydrogen and fuel cell technologies, capabilities it is important to further develop so that Norwegian actors can supply high class hydrogen and fuel cell technologies to global markets

    In 2003, President George W. Bush announced the Hydrogen Fuel Initiative to accelerate the research and development of hydrogen, fuel cell, and infrastructure technologies that would enable hydrogen fuel cell vehicles to reach the commercial market in the 2020 timeframe. The widespread use of hydrogen can reduce our dependence on imported oil and benefit the environment by reducing greenhouse gas emissions and criteria pollutant emissions that affect our air quality. The Energy Policy Act of 2005, passed by Congress and signed into law by President Bush on August 8, 2005, reinforces Federal government support for hydrogen and fuel cell technologies. Title VIII, also called the 'Spark M. Matsunaga Hydrogen Act of 2005' authorizes more than $3.2 billion for hydrogen and fuel cell activities intended to enable the commercial introduction of hydrogen fuel cell vehicles by 2020, consistent with the Hydrogen Fuel Initiative. Numerous other titles in the Act call for related tax and market incentives, new studies, collaboration with alternative fuels and renewable energy programs, and broadened demonstrations--clearly demonstrating the strong support among members of Congress for the development and use of hydrogen fuel cell technologies. In 2006, the President announced the Advanced Energy Initiative (AEI) to accelerate research on technologies with the potential to reduce near-term oil use in the transportation sector--batteries for hybrid vehicles and cellulosic ethanol--and advance activities under the Hydrogen Fuel Initiative. The AEI also supports research to reduce the cost of electricity production technologies in the stationary sector such as clean coal, nuclear energy, solar photovoltaics, and wind energy.

    Full Text Available At the present stage for human civilization is characterized the widespread use of simulations that have spread to all spheres of public life. The use of simulation in the mass media practice, in particular in order to manipulate public opinion, is radically transforming the functional characteristics of the media. The purpose of the research lies in understanding the basic assumptions of the Jean Baudrillard’s simulation theory, installation of simulacra use features in the communication processes of modern society, investigating the influence of simulacra to transform the functions of mass media. When conducting  the research tudies, are used such methods: descriptive, method of analysis, synthesis, comparison.Results. Media and official sources are used in order to maintain the illusion of truth, realityof  goals of social processes of past and present as well, objectivity of facts and documentary evidence. Abstraction, history artifacts, disasters and crises represented on television, are designed to keep the audience under the influence of communication investments. Media reports are characterized by the social codification, which is reflected in the appointment of messages not in delivering of information, implementation of communication, but only in the circulation and identification of anticipated reactions.Media plays the role of global communication environment, in which simulation mechanism is implemented. The real mass media practice suggests the use of communication resources, traditional and innovative forms of work in the plantation of simulacra world in the public consciousness as a reality.As a result, the total use of simulacra in mass media practice causes the destruction of "mass media" which appears in the functional transformation of the notion of the media as truth. To the lost belongs the function to be truth of absolute observation and supervision that is based on the position "observe" after objective space and be

    Manufacturing of hydrogen from hydrocarbon fuels is needed for a variety of applications. These applications include fuel cells used in stationary electric power production and in vehicular propulsion. Hydrogen can also be used for various combustion engine systems. There is a wide range of requirements on the capacity of the hydrogen manufacturing system, the purity of the hydrogen fuel, and capability for rapid response. The overall objectives of a hydrogen manufacturing facility are to operate with high availability at the lowest possible cost and to have minimal adverse environmental impact. Plasma technology has potential to significantly alleviate shortcomings of conventional means of manufacturing hydrogen. These shortcomings include cost and deterioration of catalysts; limitations on hydrogen production from heavy hydrocarbons; limitations on rapid response; and size and weight requirements. In addition, use of plasma technology could provide for a greater variety of operating modes; in particular the possibility of virtual elimination of CO{sub 2} production by pyrolytic operation. This mode of hydrogen production may be of increasing importance due to recent additional evidence of global warming.
