    2003-01-01

    Full Text Available In this paper we derived some simple criteria for non-existence and partial non-existence Laurent polynomial first integrals for a general nonlinear systems of ordinary differential equations $\\dot x = f(x$, $x \\in \\mathbb{R}^n$ with $f(0 = 0$. We show that if the eigenvalues of the Jacobi matrix of the vector field $f(x$ are $\\mathbb{Z}$-independent, then the system has no nontrivial Laurent polynomial integrals.

  4. Singularity confinement for maps with the Laurent property

    International Nuclear Information System (INIS)

    Hone, A.N.W.

    2007-01-01

    The singularity confinement test is very useful for isolating integrable cases of discrete-time dynamical systems, but it does not provide a sufficient criterion for integrability. Quite recently a new property of the bilinear equations appearing in discrete soliton theory has been noticed: The iterates of such equations are Laurent polynomials in the initial data. A large class of non-integrable mappings of the plane are presented which both possess this Laurent property and have confined singularities

  5. On q-extension of Laurent expansion with applications

    2014-01-01

    Full Text Available In this article, Cauchy’s integral formula for nth q-derivative of analytic functions is established and used to introduce a new proof to q-Taylor series by means of using the residue calculus in the complex analysis. Some theorems related to this formula are presented. A q-extension of a Laurent expansion is derived and proved by means of using Cauchy’s integral formula for a function, which is analytic on a ring-shaped region bounded by two concentric circles. Three illustrative examples are presented to be as applications for a q-Laurent expansion.

    Full Text Available In the context of development of economic relations, national accounting is a necessity. Building a system of information on gross domestic product, size of national wealth, financial relations and cash flows determine studies on the economic forecast, the distribution and accumulation of national wealth. Efforts in this direction have been numerous and have their roots in the work of Antoine Laurent Lavoisier . He was he who first promulgated the concepts and specific national accounting methods. He was a precursor of modern economic thought.

    Full Text Available Herein, we present a summary about the contribution to the herpetology by Raymond F. Laurent (1916-2005 who was the first president of the Asociación Herpetologica Argentina. Born in Belgium, he worked as researcher at Royal Museum for Central Africa in Tervuren and at Harvard University, and explored the herpetology in Uvira, Rwanda and Katanga. In 1964 he moved to San Miguel de Tucumán (Argentina to research in CONICET and Fundación Miguel Lillo, and to teach at the Universidad Nacional de Tucumán. He published more than 200 papers on taxonomy, systematics and morphology of African and South American herpetofauna. Most of these studies still constitute the basis to understand some classifications. As the first AHA’s president, he encouraged young people to carry on new research topics and was a caring mentor and a major influence in the development of the career of many Argentine herpetologists. Furthermore, he contributed to increase the level of the Herpetology among the Biological Sciences in Argentina.

  15. Diophantine non-integrability of a third-order recurrence with the Laurent property

    International Nuclear Information System (INIS)

    Hone, A N W

    2006-01-01

    We consider a one-parameter family of third-order nonlinear recurrence relations. Each member of this family satisfies the singularity confinement test, has a conserved quantity, and moreover has the Laurent property: all of the iterates are Laurent polynomials in the initial data. However, we show that these recurrences are not Diophantine integrable according to the definition proposed by Halburd (2005 J. Phys. A: Math. Gen. 38 L1). Explicit bounds on the asymptotic growth of the heights of iterates are obtained for a special choice of initial data. As a by-product of our analysis, infinitely many solutions are found for a certain family of Diophantine equations, studied by Mordell, that includes Markoff's equation. (letter to the editor)

    1990-01-01

    Full Text Available The classical theorems of Taylor, Lagrange, Laurent and Teixeira, are extended from the representation of a complex function F(z, to its derivative F(ν(z of complex order ν, understood as either a ‘Liouville’ (1832 or a ‘Rieman (1847’ differintegration (Campos 1984, 1985; these results are distinct from, and alternative to, other extensions of Taylor's series using differintegrations (Osler 1972, Lavoie & Osler & Tremblay 1976. We consider a complex function F(z, which is analytic (has an isolated singularity at ζ, and expand its derivative of complex order F(ν(z, in an ascending (ascending-descending series of powers of an auxiliary function f(z, yielding the generalized Teixeira (Lagrange series, which includes, for f(z=z−ζ, the generalized Taylor (Laurent series. The generalized series involve non-integral powers and/or coefficients evaluated by fractional derivatives or integrals, except in the case ν=0, when the classical theorems of Taylor (1715, Lagrange (1770, Laurent (1843 and Teixeira (1900 are regained. As an application, these generalized series can be used to generate special functions with complex parameters (Campos 1986, e.g., the Hermite and Bessel types.

  18. Laurent series expansion of sunrise-type diagrams using configuration space techniques

    International Nuclear Information System (INIS)

    Groote, S.; Koerner, J.G.; Pivovarov, A.A.

    2004-01-01

    We show that configuration space techniques can be used to efficiently calculate the complete Laurent series ε-expansion of sunrise-type diagrams to any loop order in D-dimensional space-time for any external momentum and for arbitrary mass configurations. For negative powers of ε the results are obtained in analytical form. For positive powers of ε including the finite ε 0 contribution the result is obtained numerically in terms of low-dimensional integrals. We present general features of the calculation and provide exemplary results up to five-loop order which are compared to available results in the literature. (orig.)

  2. Antoine-Laurent de Lavoisier (1743-1794) and the birth of respiratory physiology.

    Science.gov (United States)

    Karamanou, Marianna; Androutsos, George

    2013-10-01

    For more than 1500 years, the status of knowledge concerning the physiology of human respiration has remained almost unchanged. In the 18th century, the French chemist Antoine-Laurent de Lavoisier conducted breathing experiments on human and animal respiration. The main bibliographic sources concerning Lavoisier's life and work on respiration have been investigated and analysed. Using an ice-calorimeter, Lavoisier proved that combustion and respiration were one and the same. He also measured the oxygen consumed during respiration and concluded that the amount changes depending on human activities: exercise, eating, fasting, and sitting in a warm or cold room. Moreover, he found variations in pulse and breathing rate. Lavoisier's work on respiration is of great historical significance as it represents the first effort to measure human respiratory gas metabolism contributing significantly to the development of respiratory physiology.

    Full Text Available Jean Laurent, a French photographer established in Madrid, reproduced works of art from major collections in Spain, and undertook an extensive survey of views of places and works of architecture in this country. In late winter and spring of 1869, he visited Portugal, where he photographed the royal family and extended his survey to the entire Iberian Peninsula. He travelled the country mostly by train with his small laboratory car, which he unloaded at each location of his itinerary, to sensitize and develop the images obtained with the wet collodion process. He was probably the first photographer to explore the potential of the railway, recently built in the Iberian Peninsula. His collection of images can be regarded as the most significant among those produced by photographers who globally depicted the Peninsula during the 19th century.

    2015-12-01

    Full Text Available XXth century history obliged narrators to clash with events that was literally inexpressible, measuring the potential and the lack of literary means. Laurent Mauvignier made this confrontarion the centre of his poetics: from minimal, private tragedies to great, historical dramas, passing through the media mystification of absurd fait divers, his novels face the Evil problem and its representation in words. With Des hommes (2009, Mauvignier addresses his question to one of the most problematic repression object in historical French memory: Algerian War. Building a polyphonic novel, he deals with an event deeply characterized by silence (the veteran silence studied by Benjamin Stora and Andrea Brazzoduro and that has been manipulated by the institutional and mediatic vulgata. Infact, the narration shows how the amnesty of collective faults is based on the "order to say nothing" (overturning Foucault, first of all caused by the social load of an history that nobody wants. This paper aims at showing how Mauvignier's work, inspired by modernist novel and "nouveau roman" (Duras, Simon, resorts to literary experimentalism to "défamiliariser" this historical event using the tools of a fiction claiming the value of a "secondary experience" to redeem a piece of history refused by the public discourse.

    The squat lobster, Munidopsis lauensis Baba & de Saint Laurent, 1992, is recorded from Taiwan for the first time. This species was previously known only from deep-sea hydrothermal vents in the South-West Pacific but it was now found at a deep-sea cold seep site off southwestern Taiwan. The identity of the Taiwanese material is confirmed by comparison of sequences from the barcoding gene COI. Munidopsis lauensis can be easily separated from other congeners in Taiwanese waters by the eyes bearing a strong mesiodorsal spine and a small mesioventral spine, smooth carapace, fingers of the cheliped distally spooned and fixed finger without a denticulate carina on the distolateral margin. The discovery of this species in Taiwan increases the Munidopsis fauna of the island to 38 species. A color photograph and line drawings illustrating distinctive characters are provided for the Taiwanese material.

Trois commandes passées successivement entre 1846 et 1888 à des artistes de renom témoignent de l’évolution de cet art depuis les premières recherches vers 1820 jusqu’à la parfaite maîtrise d’une technique, perdue au siècle précédent faute de commande. L’iconographie de ces trois séries de verrières, dont l’évolution stylistique est à mettre en parallèle avec les autres arts, reflètent les différentes dévotions d’une société liée aux pratiques gallicanes avant de rallier le courant ultramontain. Enfin, des différences au niveau des signatures témoignent de l’évolution de la perception du métier de peintre verrier par leurs contemporains.The Saint-Laurent church in Paris is a good example of how stained glass witnessed a renaissance during the nineteenth century. Three commissions signed between 1846 and 1888 with stained glass artists of renown bear witness to the evolution of this art from early researches in the 1820s to complete technical mastery, lost during the preceding century for lack of commands. The iconography of the three series of stained glass windows, which is to be compared with the evolution in other arts, reflects the different devotional features of a society linked to Gallican practices before going over to more ultramontain tendencies. Differences in the importance accorded to the signature of the artist also gives an indication of how the status of the stained glass artist was perceived by their contemporaries.

  1. Saint-Laurent-des-Eaux plant - Report on the complementary safety assessment of nuclear facilities in the light of the Fukushima accident

    International Nuclear Information System (INIS)

    2011-01-01

    This CSA (Complementary Safety Assessment) analyses the robustness of the Saint-Laurent-des-Eaux plant to extreme situations such as those that led to the Fukushima accident and proposes a series of improvements. Robustness is the ability for the plant to withstand events beyond the level for which the plant was designed. Robustness is linked to safety margins but also to the situations leading to a sudden deterioration of the accident sequence. Safety is not only a matter of design or of engineered systems, it is also a matter of organization. So issues like EDF's crisis organization, the organization of radiation protection, and work organization via subcontracting are also taken into consideration. The creation of a nuclear rapid action force (FARN) is proposed: this will be a national emergency force made up of specialized teams equipped to intervene in less than 24 hours on a nuclear site hit by an accident. This report is divided into 8 main chapters: 1) features of the site, 2) earthquake risk, 3) flooding risk, 4) risks due to other extreme natural disasters, 5) the loss of electrical power supplies and of heat sink, 6) management of severe accidents (accidents with core melt), 7) task subcontracting policy, 8) synthesis and list of improvements. 4 following appendices review: EDF's crisis organization, the FARN, radiation protection organization and accidental event trees.

    After a brief indication of some key characteristics of the Saint-Laurent-des-Eaux nuclear power plant, this press folder outlines the good results obtained in 2012 in terms of reliability, of activity management and of significant event regarding safety (only 3). It presents the plant within the French nuclear fleet, addresses nuclear safety as the main priority (a regulated and permanently controlled activity, a transparent exploitation, first lessons learned from the Fukushima accident, risks taken into account in relationship with public authorities, the site security). It evokes the environment as an everyday concern. It addresses the site future: re-assessment of reactor safety level, investments to be prepared, rigorous management of radioactive wastes, recycling of spent fuel with the production of MOX, and deconstruction. It presents the power station as an unavoidable local economic actor (important economic spin-offs, social and occupational integration of young and of disable people, partnership with local actors). It finally evokes continuous public information, indicates some key figures and key dates for 2012

    Résumé OBJECTIF Le but de cette étude était d’évaluer l’impact sur la rétention des médecins omnipraticiens du programme d’enseignement décentralisé, des mesures incitatives financières et de l’origine du médecin. DEVIS Nos données sont tirées de la banque du suivi des effectifs médicaux de la Régie régionale de la santé et des services sociaux du Bas-Saint-Laurent. Les questionnaires complétés par les médecins dans le cadre de cette étude ont été envoyés par la poste. MILIEU Bas-Saint-Laurent, Qué. PARTICIPANTS Des médecins omnipraticiens pratiquant depuis 1985 à août 2003 dans la région. MÉTHODOLOGIE Pour les analyses statistiques, nous avons fait appel à l’analyse multivariée, en utilisant le modèle des taux proportionnels de Cox de l’analyse de survie. RÉSULTATS La probabilité ajustée de demeurer en région, selon l’exposition aux stages de résidence en région, présente une tendance positive avec un rapport de 2,12 (P = 0,15). La probabilité de rester dans la région grimpe jusqu’à 4,5 fois plus (P du Bas-Saint-Laurent. Le lien avec les mesures incitatives financières montre que la probabilité ajustée de demeurer dans le Bas-Saint-Laurent n’est pas significativement différente selon qu’ils aient ou non reçu les primes d’installation ou la bourse de la Régie de l’assurance-maladie du Québec. CONCLUSION Les facteurs les plus prometteurs pour retenir les médecins omnipraticiens en région touchent le recrutement en médecine de candidats des régions rurales et la formation décentralisée.

    Short-rotation intensive culture on abandoned farmlands has been used successfully in Sweden to produce woody biomass as a renewable energy source. Because of changing economic conditions, thousands of hectares of farmland are abandoned every year in Quebec. Although it is impractical to use this land to farm conventional crops, it is nevertheless well-suited for tree plantations. In Quebec, experiments with this method have been conducted since 1995 in the rural municipality of Haut Saint-Laurent to farm Salix discolor and Salix viminalis as sources of biomass fuels. The final results of Phase I of this project were presented. This first phase, from 1995-1998, included the period from the planting to the first harvesting of willow branches on a total of six hectares of abandoned farmlands. Three of these hectares were on well-drained sandy soils and three on poorly-drained clay soils. Specific recommendations on farming and harvesting methods are made. 48 refs., 14 tabs., 10 figs.

    Short-rotation intensive culture (SRIC) on abandoned farmlands has successfully been used in Sweden to produce woody biomass as a renewable energy source. Because of changing economic conditions, thousands of hectares of farmland are abandoned every year in Quebec. Although it is impractical to use this land to farm conventional crops, it is nevertheless well-suited for tree plantations. In Quebec, experiments with this method have been conducted since 1995 in the rural municipality of Haut Saint-Laurent to farm Salix discolor and Salix viminalis as sources of biomass fuels. Results of work done from 2000 to 2001 in the context of Phase 2 of this project were presented. During this time, the regrowth of branches was evaluated following the harvesting of the first crop of branches at the end of 1997. A total of six hectares were planted; three on well-drained sandy soils and three on poorly-drained clay soils. In addition, the results of a new project initiated in collaboration with researchers at the State University of New York (SUNY) were also presented. This last project involved the planting of two clones of poplar and ten clones of willow on a single hectare of land, always with the objective of producing biomass fuels. 59 refs., 12 tabs., 4 figs.

    2011-10-01

    Full Text Available Cantet's movie “Vers le sud/ Heading South“ (2005 explores cultural stereotypes and values without being moralizing in a common sense. His drama deals with female sex tourism, political and social violence, power and money in such a way that people are tempted to judge the protagonists: Their desire for young black men is called “embarrassing“, they are seen as corrupting and as actors in a new kind of imperialism. In fact the images in the film organize characters in a certain kind of dualism which leads easily to these argumentations. But having a look at the cultural values that produce the disgust, we see that they are all open to question.

    A study was conducted to determine how the proposed construction of a large building complex along Sainte-Catherine Street in Montreal will influence the movement of air in the city block and the comfort of pedestrians. Different configurations of wind interactions were simulated using a 1/225 scaled version of the proposed construction. This report described the methodology and study results. It included an analysis of wind regimes at the site. During the simulations, the movement of air around the building complex was reproduced to scale. Wind speed measurements were taken at 33 reference points. It was concluded that the construction of the complex may result in discomfort to pedestrians on the sidewalks as well as those in a covered passages. The installation of a deflector or planting of vegetation may reduce some of the discomfort. Alternatively, a change in the building's geometry may diminish some of the wind impact. 3 refs., 2 tabs., 6 figs.

    We present a new self-drilling self-tapping dental implant that simplifies the operative technique and optimizes osseointegration. The implant, the instrumentation, and the operative technique are described. An experimental study was conducted in a sheep with pathological and histomorphological analysis at three months. A clinical evaluation was also conducted in 18 patients who had 27 implants. The experimental study demonstrated good quality osseointegration, without bone necrosis. Three sectors were identified. Histomorphometric analysis demonstrated that mean bone contact reached 40% on cancellous bone and 65% on cortical bone. In the clinical series, one implant had to be removed due to a problem with gum healing. All the other implants were well tolerated. The advantage of this new technique is the use of the implant as the drilling instrument. Much time is saved. In addition, the bone-implant contact is better since the bone cavity is exactly adapted to the implant. The risk of bone lesion is reduced due to the smaller number of drillings.

  17. Radioactivity monitoring within the environment of the Loire basin. A partnership between the IRSN and the Dampierre-en-Burly and Saint-Laurent CLIs at the service of citizen vigilance

    International Nuclear Information System (INIS)

    2008-01-01

    The first part of this report presents the Loire basin and its environment, discusses the physical-chemical quality control of its waters and the main usages of the Loire waters. It also presents the nuclear installations present in the Loire basin (electricity production nuclear power stations and other installations), the actors involved in radioactivity measurement in the Loire basin environment (IRSN, EDF, AREVA, associations for the monitoring of water quality, public services), and the national network for radioactivity measurement in the environment. The second part describes and reports the radioactivity monitoring of the environment in the Loire basin, i.e. in the atmosphere, in rain waters and in continental waters, and in the food chain. Addressing this monitoring activity, a last part discusses the evolution of measurements, the importance of the plurality of actors involved in sampling and measurement (in order to guarantee the monitoring system transparency), the variety of sources, the assessment of health impact

    The authors reported on a project designed to provide farmers with concrete information based on data from their enterprise to develop an action plan for the reduction of greenhouse gas emissions. This project involved completing an inventory of greenhouse gas emissions and capture for seven farms located in the Lower Saint Lawrence region of Quebec. The authors presented a balance sheet and action plan for the region under study. A total of six priorities were identified. They encompassed measures such as the optimization of nitrogen management in agricultural soils, to increasing the capture rate of carbon dioxide, and reducing the use of fossil fuels. 6 refs., 6 figs.

  2. Issues related to seismic surveys in the Estuary and Gulf of St. Lawrence : public inquiry report; Les enjeux lies aux leves sismiques dans l'estuaire et le golfe du Saint-Laurent : rapport d'enquete et d'audience publique

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2004-08-01

    Quebec's Office of Public Inquiry on the Environment (Bureau d'audiences publiques sur l'environnement) conducted public hearings on the environmental issues associated with seismic surveys carried out in the Gulf of St. Lawrence and its estuaries for the purpose of petroleum and natural gas exploration. The inquiry focused on the effect of sound waves on aquatic ecosystems and marine organisms and the associated environmental, social and economic consequences of seismic surveys. Environmental groups, scientists, fishermen and the maritime tourist industry have been concerned with the impact of seismic surveys in the Estuary and the Gulf of St. Lawrence since the autumn of 2002, when Hydro-Quebec publicized its 2002-2010 plan for oil and gas exploration and when Geophysical Service Inc. received a mandate from Hydro-Quebec to carry out seismic surveys in the area. This report presents 10 recommendations and 16 opinions resulting from 18 public hearings held in communities along the Gulf of St. Lawrence. Although the thousands of kilometres of seismic survey lines acquired in the Estuary and the Gulf of St. Lawrence since 1960 do not seem to have had any visible impact on the marine environment, the Commission has taken a precautionary approach and recommends that some practices should be limited until a review of literature demonstrates that seismic surveys do not affect the ecological integrity of the St. Lawrence for fisheries or ecotourism. 16 refs., 9 tabs., 5 figs., 2 appendices.

The introduction introduces...... the basic concepts on which the papers build. Among other it introduces metric Diophantine approximation, Mahler’s approach on algebraic approximation, the Hausdorff measure, and properties of the formal Laurent series over Fq. The introduction ends with a discussion on Mahler’s problem when considered...... in the formal Laurent series over F3. The first paper is on intrinsic Diophantine approximation in the Cantor set in the formal Laurent series over F3. The summary contains a short motivation, the results of the paper and sketches of the proofs, mainly focusing on the ideas involved. The details of the proofs...

    1999-08-01

    An update was presented on the levels of polycyclic aromatic hydrocarbon (PAH) contamination in bottom dwelling fish and crustaceans in the Gulf of St. Lawrence and the Saguenay fjord. Attempts were made to detect specific compounds including fluoranthene, pyrene, benzo-b-fluoranthene, benzo-k-fluoranthene, benzo-a-pyrene, dibenzo-a,h-anthracene, benzo-g,h,i-perylene, naphtalene, acenaphtene, fluorene, phenanthrene, and anthracene. Concentrations of all PAHs in the muscle tissue of cod, plaice, skate and halibut were found to be below analytical detection limits. Concentrations of most PAHs were also below detection limits in halibut liver tissue and crab. The exception was benzo-a-anthracene. Shrimp muscle contained measurable levels of many PAHs. The levels were detected by fluorimetry but could not be confirmed by mass spectroscopy. Based on these results, it was concluded that the fish can be considered safe for human consumption. 3 refs., 13 tabs., 1 fig.

  3. Interfacial dynamics of dissolving objects in fluid flow

    Science.gov (United States)

    Rycroft, Chris; Bazant, Martin

    2013-11-01

    An advection-diffusion-limited dissolution model of an object being eroded by a two-dimensional potential flow will be presented. By taking advantage of conformal invariance of the model, a numerical method will be introduced that tracks the evolution of the object boundary in terms of a time-dependent Laurent series. Simulations of several dissolving objects will be shown, all of which show collapse to a single point in finite time. The simulations reveal a surprising connection between the position of the collapse point and the initial Laurent coefficients, which was subsequently derived analytically using residue calculus.

  4. The massless two-loop two-point function

    International Nuclear Information System (INIS)

    Bierenbaum, I.; Weinzierl, S.

    2003-01-01

    We consider the massless two-loop two-point function with arbitrary powers of the propagators and derive a representation from which we can obtain the Laurent expansion to any desired order in the dimensional regularization parameter ε. As a side product, we show that in the Laurent expansion of the two-loop integral only rational numbers and multiple zeta values occur. Our method of calculation obtains the two-loop integral as a convolution product of two primitive one-loop integrals. We comment on the generalization of this product structure to higher loop integrals. (orig.)

    Full Text Available The SWISS TEXT CORPUS (CHTK has made it its goal to extensively document the German language of the 20th century in Switzerland. In this way, and in its parallel function as a sub-corpus of the Corpus C4, that will consist of 20 million text words (tokens each from Germany, Austria, Italy/South Tirol and, as already said, Switzerland, it represents a classical reference corpus both for the standard German language in Switzerland as well as in the entire German-speaking area of Western Europe. A reference corpus should meet the requirement of comprehensively depicting the central repertoire of a language, i.e. the generally used vocabulary of this language, which is why questions of corpus structure and general planning (corpus design play a decisive role (cf. Lemnitzer/Zinsmeister (2006: 106, where the type of the reference corpus is contrasted with the special corpus. Four and a half years after the start of the project, the SWISS TEXT CORPUS was made available to the general public in April 2009, as a research instrument. The following article outlines in brief the history of this research project and deals with fundamental and specific decisions that had to be made in the design of such a reference corpus, and with how the CHTK is compiled. Together with a concluding overview of some retrieval and analysis options offered by the CHTK, this article also provides an overview of the potential of this new research instrument and supplies the background knowledge required to work with the CHTK. For reasons of space, the methods of working, the corpus-driven approaches, cannot be thematised here (cf. Bubenhofer 2008, 2006.

  17. arXiv Diagrammatic Hopf algebra of cut Feynman integrals: the one-loop case

    CERN Document Server

    Abreu, Samuel; Duhr, Claude; Gardi, Einan

    2017-12-15

    We construct a diagrammatic coaction acting on one-loop Feynman graphs and their cuts. The graphs are naturally identified with the corresponding (cut) Feynman integrals in dimensional regularization, whose coefficients of the Laurent expansion in the dimensional regulator are multiple polylogarithms (MPLs). Our main result is the conjecture that this diagrammatic coaction reproduces the combinatorics of the coaction on MPLs order by order in the Laurent expansion. We show that our conjecture holds in a broad range of nontrivial one-loop integrals. We then explore its consequences for the study of discontinuities of Feynman integrals, and the differential equations that they satisfy. In particular, using the diagrammatic coaction along with information from cuts, we explicitly derive differential equations for any one-loop Feynman integral. We also explain how to construct the symbol of any one-loop Feynman integral recursively. Finally, we show that our diagrammatic coaction follows, in the special case of o...

    Anaïs Schaeffer

    2011-01-01

    On display at Fort l'Écluse from 19 June to 18 September, the works of Augenblick combine photography, sound and video to create a striking instant parallel between the "real world" and the world of particle physics.   The cows are grazing quietly, blissfully unaware of the mini-Big Bang occurring silently 100 metres beneath them. Curious to compare these two worlds - the visible and the invisible, day-to-day life and particle physics - Laurent Mulot, a multi-disciplinary artist whose work delves into some of the planet's more unusual places, has come up with a unique artistic concept. Called Augenblick (German for "instant"), to emphasise that the images relate to the same point in time, his project uses photography, video and sound to superimpose scenes from everyday life and scenes from science. "The idea came to me in June 2008," says Laurent Mulot, "when Jean-Paul Martin, a research scientist at the Institute of Nuclear...

    The coupled nonlinear Klein-Gordon equations are analyzed for their integrability properties in a systematic manner through Painleve test. From the Painleve test, by truncating the Laurent series at the constant level term, the Hirota bilinear form is identified, from which one-soliton solutions are derived. Then, the results are generalized to the two, three and N-coupled Klein-Gordon equations

  11. Muscular proprioception contributes to the control of interceptive actions.

    OpenAIRE

    2006-01-01

    International audience; The authors proposed a model of the control of interceptive action over a ground plane (Chardenon, Montagne, Laurent, & Bootsma, 2004). This model is based on the cancellation of the rate of change of the angle between the current position of the target and the direction of displacement (i.e., the bearing angle). While several sources of visual information specify this angle, the contribution of proprioceptive information has not been directly tested. In this study, th...

    Visual attention is captured by physically salient stimuli (termed salience-based attentional capture), and by otherwise task-irrelevant stimuli that contain goal-related features (termed contingent attentional capture). Recently, we reported that physically nonsalient stimuli associated with value through reward learning also capture attention involuntarily (Anderson, Laurent, & Yantis, PNAS, 2011). Although it is known that physical salience and goal-relatedness both influence attentional p...

    concept of luxury as opposed to the social significance that luxury possessed in premodern societies. The evolution of luxury is seen within the context of the evolution of fashion, highlighting how it participates in the emergence of modern forms of display of individual desire. This evolution is analyzed through four historical examples: the dandy “Beau” Brummell, the haute couture initiated by Frederik Worth, the creations of Yves Saint Laurent and the collections that Karl Lagerfeld developed for H&M.

    We refine the Fuchs inequalities obtained by Corel for systems of linear meromorphic differential equations given on the Riemann sphere. Fuchs inequalities enable one to estimate the sum of exponents of the system over all its singular points. We refine these well-known inequalities by considering the Jordan structure of the leading coefficient of the Laurent series for the matrix of the right-hand side of the system in the neighbourhood of a singular point

    The factorization rules of Li [J. Opt. Soc. Am. A 13, 1870 (1996)] are generalized to a cylindrical geometry requiring the use of a Bessel function basis. A theoretical study confirms the validity of the Laurent rule when a product of two continuous functions or of one continuous and one discontinuous function is factorized. The necessity of applying the so-called inverse rule in factorizing a continuous product of two discontinuous functions in a truncated basis is demonstrated theoretically and numerically.

    2016-08-25

    A molecular phylogeny of the Afrotropical anuran genus Amietia based on 323 16S sequences indicates that there are 19 species, including four not yet described. No genetic material was available for the nominal A. inyangae. We consider them to represent full species, and define them based on 16S genetic distances, as well as differences in morphology, tadpoles and advertisement call where known. An analysis based on two mitochondrial and two nuclear genes (12S, 16S, 28S and tyrosinase exon 1), from 122 samples, confirmed the phylogenetic relationships suggested by the 16S tree. We recognise and (re-) describe the following species: Amietia angolensis (Bocage, 1866), A. chapini (Noble, 1924), A. delalandii (Duméril & Bibron, 1841), A. desaegeri (Laurent, 1972), A. fuscigula (Duméril & Bibron, 1841), A. hymenopus (Boulenger, 1920), A. inyangae (Poynton, 1966), A. johnstoni (Günther, 1893), A. moyerorum sp. nov., A. nutti (Boulenger, 1896), A. poyntoni Channing & Baptista, 2013, A. ruwenzorica (Laurent, 1972), A. tenuoplicata (Pickersgill, 2007), A. vandijki (Visser & Channing, 1997), A. vertebralis (Hewitt, 1927), and A. wittei (Angel, 1924). Three further candidate species of Larson et al. (2016) await formal naming. We provisionally regard A. amieti (Laurent, 1976) as a junior synonym of A. chapini (Noble, 1924). Amietia lubrica (Pickersgill, 2007) is shown to be a junior synonym of A. nutti, while A. quecketti (Boulenger, 1895) is shown to be a junior synonym of A. delalandii (Duméril & Bibron, 1841), and A. viridireticulata (Pickersgill, 2007) is placed as a junior synonym of A. tenuoplicata (Pickersgill, 2007). On the basis of similarity of 16S sequences, we assign A. sp. 1, A. sp. 3 and A. sp. 6 of Larson et al (2016) to the nomina A. chapini (Noble, 1924), A. desaegeri (Laurent, 1972), and A. nutti (Boulenger, 1896) respectively.

    Full Text Available Antioxidants are specific substances that oxidize themselves and in this way they protect other sensitive bioactive food components against destruction. At the same time they restrict the activity of free radicals and change them to less active forms. Large group of antioxidants are polyphenols, which affect sensory properties of fruit, vegetable and some drinks, like colour (anthocyans, taste (flavonoids or odour (phenols. The significant source of polyphenolic compounds are wines. Polyphenols (in optimal amount and combination, found mainly in red wines, have very complex (positive effects on organism. The aim of this work was to determine chosen antioxidant properties of the best-selling quality red wines - Blaufränkisch and St. Laurent, originating from different Slovak vineyard areas. Total polyphenols content was determined with phenol Folin-Ciocalteau´s reagent and antioxidant activity was determined using DPPH stable free radical. Both parameters were determined by UV-VIS absorption spectrometry. The determined total polyphenol contents in observed wines were within the interval 1579 – 2734 mg.L-1 (Blaufränkisch, respectively 1409 – 3276 mg.L-1 (St. Laurent. Antioxidant activity in wines was within the interval 80.2 – 86.4 % (Blaufränkisch, respectively 71.0 – 84.8 % (St. Laurent. The differences between results of measured antioxidant properties (total polyphenol contents and antioxidant activities of the wines originating from some vineyard Slovak areas were statistically significant.

  7. Periodic cluster mutations and related integrable maps

    International Nuclear Information System (INIS)

    Fordy, Allan P

    2014-01-01

    One of the remarkable properties of cluster algebras is that any cluster, obtained from a sequence of mutations from an initial cluster, can be written as a Laurent polynomial in the initial cluster (known as the ‘Laurent phenomenon’). There are many nonlinear recurrences which exhibit the Laurent phenomenon and thus unexpectedly generate integer sequences. The mutation of a typical quiver will not generate a recurrence, but rather an erratic sequence of exchange relations. How do we ‘design’ a quiver which gives rise to a given recurrence? A key role is played by the concept of ‘periodic cluster mutation’, introduced in 2009. Each recurrence corresponds to a finite dimensional map. In the context of cluster mutations, these are called ‘cluster maps’. What properties do cluster maps have? Are they integrable in some standard sense?In this review I describe how integrable maps arise in the context of cluster mutations. I first explain the concept of ‘periodic cluster mutation’, giving some classification results. I then give a review of what is meant by an integrable map and apply this to cluster maps. Two classes of integrable maps are related to interesting monodromy problems, which generate interesting Poisson algebras of functions, used to prove complete integrability and a linearization. A connection to the Hirota–Miwa equation is explained. This article is part of a special issue of Journal of Physics A: Mathematical and Theoretical devoted to ‘Cluster algebras in mathematical physics’. (review)

  8. Irreducibility and co-primeness as an integrability criterion for discrete equations

    International Nuclear Information System (INIS)

    Kanki, Masataka; Mada, Jun; Mase, Takafumi; Tokihiro, Tetsuji

    2014-01-01

    We study the Laurent property, the irreducibility and co-primeness of discrete integrable and non-integrable equations. First we study a discrete integrable equation related to the Somos-4 sequence, and also a non-integrable equation as a comparison. We prove that the conditions of irreducibility and co-primeness hold only in the integrable case. Next, we generalize our previous results on the singularities of the discrete Korteweg–de Vries (dKdV) equation. In our previous paper (Kanki et al 2014 J. Phys. A: Math. Theor. 47 065201) we described the singularity confinement test (one of the integrability criteria) using the Laurent property, and the irreducibility, and co-primeness of the terms in the bilinear dKdV equation, in which we only considered simplified boundary conditions. This restriction was needed to obtain simple (monomial) relations between the bilinear form and the nonlinear form of the dKdV equation. In this paper, we prove the co-primeness of the terms in the nonlinear dKdV equation for general initial conditions and boundary conditions, by using the localization of Laurent rings and the interchange of the axes. We assert that co-primeness of the terms can be used as a new integrability criterion, which is a mathematical re-interpretation of the confinement of singularities in the case of discrete equations.

    2013-10-01

    We present the master integrals needed for the light fermionic two-loop corrections to top quark pair production in the gluon fusion channel. Via the method of differential equations we compute the results in terms of multiple polylogarithms in a Laurent series about d = 4, where d is the space-time dimension. The most involved topology is a non-planar double box with one internal mass. We employ the coproduct-augmented symbol calculus and show that significant simplifications are possible for selected results using an optimised set of multiple polylogarithms.

  10. On the density of the Ward Ansaetze in the space of anti-self-dual Yang Mills solutions

    1990-01-01

    A general patching matrix P for the twistor construction of anti-self-dual Yang-Mills fields is approximated by a terminating Laurent series. The approximate patching matrix P (m) is triangularized (so that it becomes one of the Ward ansaetze) and the associated Riemann-Hilbert problem is solved, thereby generating an anti-self-dual solution of the Yang-Mills equations. The approximate patching matrices and the associated (exact) anti-self-dual Yang-Mills solutions are then shown to converge on P and its corresponding solution so that the Ward ansaetze forms a dense subset in the solution space in the Weierstrass sense.

    We consider a two dimensional extension of the so-called linearizable mappings. In particular, we start from the Heideman-Hogan recurrence, which is known as one of the linearizable Somos-like recurrences, and introduce one of its two dimensional extensions. The two dimensional lattice equation we present is linearizable in both directions, and has the Laurent and the coprimeness properties. Moreover, its reduction produces a generalized family of the Heideman-Hogan recurrence. Higher order examples of two dimensional linearizable lattice equations related to the Dana Scott recurrence are also discussed.

    on Thévenot's notion of ‘commonality in the plural’, the article shows how a range of personal affinities to the architectural form of the kyō-machiya, positioned as an urban ‘common-place’, serves to coordinate across otherwise divergent interests. By taking seriously the role of attachments to common-places...... change. To understand the dynamic interplay of architecture and community-building in this case, the article stages a theoretical debate on the politics of shared attachments between three proponents of French pragmatic sociology: Bruno Latour, Antoine Hennion, and Laurent Thévenot.

    It is an open question whether the chromatic number of $t$-perfect graphs is bounded by a constant. The largest known value for this parameter is 4, and the only example of a 4-critical $t$-perfect graph, due to Laurent and Seymour, is the complement of the line graph of the prism $\\Pi$ (a graph is 4-critical if it has chromatic number 4 and all its proper induced subgraphs are 3-colorable). In this paper, we show a new example of a 4-critical $t$-perfect graph: the complement of the line gra...

    The freshly injected antiprotons, while circulating on the injection orbit, were subjected to fast stochastic "precooling" for several seconds (in momentum and in the vertical plane). This precooling pickup is being readied by Gerard Laurent for installation in its tank. Precooling PUs and kickers were of identical construction (except for the kickers having cooling circuits), with C-shaped ferrites sandwiched between C-shaped metal plates and couplers at the back of the C. For reasons explained in 8002234, they were also equipped with shutters which closed the open side of the C when there was beam on the injection orbit. For more on precooling see 8020234, 8004064.

    2014-05-01

    In order to lower the computational cost of the variational data assimilation process, we investigate the use of multigrid methods to solve the associated optimal control system. On a linear advection equation, we study the impact of the regularization term on the optimal control and the impact of discretization errors on the efficiency of the coarse grid correction step. We show that even if the optimal control problem leads to the solution of an elliptic system, numerical errors introduced by the discretization can alter the success of the multigrid methods. The view of the multigrid iteration as a preconditioner for a Krylov optimization method leads to a more robust algorithm. A scale dependent weighting of the multigrid preconditioner and the usual background error covariance matrix based preconditioner is proposed and brings significant improvements.

  20. Habitat heterogeneity in the assemblages and shell use by the most abundant hermit crabs (Anomura: Diogenidae and Paguridae: does the occupied shell species differ according to gender and species?

    Directory of Open Access Journals (Sweden)

    Gilson Stanski

    Full Text Available Abstract The goal of this study was to identify patterns of shell occupation by different species of hermit crabs from the southern Brazilian coast. In total, 644 individuals were collected, represented by six hermit species. Isocheles sawayai Forest & Saint Laurent, 1968 showed the highest abundance, with 575 individuals, followed by Loxopagurus loxochelis (Moreira, 1901 (n = 56. The other species were Petrochirus diogenes (Linnaeus, 1758, Dardanus insignis (Saussure, 1858, Pagurus exilis (Benedict, 1892 and Pagurus leptonyx Forest & Saint Laurent, 1968. Loxopagurus loxochelis was found associated with shells of 12 gastropod species, with 75% of males occupying shells of Olivancilaria urceus (Roding, 1798 and 78% of females inhabiting shells of Semicassis granulata (Born, 1778. Shells of Semicassis granulata were the lightest of all gastropod shells, demonstrating differential resource utilization. Additionally, I. sawayai occupied shells of 10 species, highlighting Stramonita haemastoma (Linnaeus, 1767 with the highest occupation percentage in all demographic classes, confirming a pattern of occupation with a strong relationship to the availability of the resource. The comparison of our results with those of other studies corroborated the influence of region and gastropod diversity on gastropod shell occupation.

  1. Hierarchy of modular graph identities

    Energy Technology Data Exchange (ETDEWEB)

    D’Hoker, Eric; Kaidi, Justin [Mani L. Bhaumik Institute for Theoretical Physics, Department of Physics and Astronomy,University of California,Los Angeles, CA 90095 (United States)

    The low energy expansion of Type II superstring amplitudes at genus one is organized in terms of modular graph functions associated with Feynman graphs of a conformal scalar field on the torus. In earlier work, surprising identities between two-loop graphs at all weights, and between higher-loop graphs of weights four and five were constructed. In the present paper, these results are generalized in two complementary directions. First, all identities at weight six and all dihedral identities at weight seven are obtained and proven. Whenever the Laurent polynomial at the cusp is available, the form of these identities confirms the pattern by which the vanishing of the Laurent polynomial governs the full modular identity. Second, the family of modular graph functions is extended to include all graphs with derivative couplings and worldsheet fermions. These extended families of modular graph functions are shown to obey a hierarchy of inhomogeneous Laplace eigenvalue equations. The eigenvalues are calculated analytically for the simplest infinite sub-families and obtained by Maple for successively more complicated sub-families. The spectrum is shown to consist solely of eigenvalues s(s−1) for positive integers s bounded by the weight, with multiplicities which exhibit rich representation-theoretic patterns.

  2. Exact solution of corner-modified banded block-Toeplitz eigensystems

    2017-05-01

    Motivated by the challenge of seeking a rigorous foundation for the bulk-boundary correspondence for free fermions, we introduce an algorithm for determining exactly the spectrum and a generalized-eigenvector basis of a class of banded block quasi-Toeplitz matrices that we call corner-modified. Corner modifications of otherwise arbitrary banded block-Toeplitz matrices capture the effect of boundary conditions and the associated breakdown of translational invariance. Our algorithm leverages the interplay between a non-standard, projector-based method of kernel determination (physically, a bulk-boundary separation) and families of linear representations of the algebra of matrix Laurent polynomials. Thanks to the fact that these representations act on infinite-dimensional carrier spaces in which translation symmetry is restored, it becomes possible to determine the eigensystem of an auxiliary projected block-Laurent matrix. This results in an analytic eigenvector Ansatz, independent of the system size, which we prove is guaranteed to contain the full solution of the original finite-dimensional problem. The actual solution is then obtained by imposing compatibility with a boundary matrix, whose shape is also independent of system size. As an application, we show analytically that eigenvectors of short-ranged fermionic tight-binding models may display power-law corrections to exponential behavior, and demonstrate the phenomenon for the paradigmatic Majorana chain of Kitaev.

  3. Calculating three loop ladder and V-topologies for massive operator matrix elements by computer algebra

    International Nuclear Information System (INIS)

    Ablinger, J.; Schneider, C.; Manteuffel, A. von

    2015-09-01

    Three loop ladder and V-topology diagrams contributing to the massive operator matrix element A Qg are calculated. The corresponding objects can all be expressed in terms of nested sums and recurrences depending on the Mellin variable N and the dimensional parameter ε. Given these representations, the desired Laurent series expansions in ε can be obtained with the help of our computer algebra toolbox. Here we rely on generalized hypergeometric functions and Mellin-Barnes representations, on difference ring algorithms for symbolic summation, on an optimized version of the multivariate Almkvist-Zeilberger algorithm for symbolic integration, and on new methods to calculate Laurent series solutions of coupled systems of differential equations. The solutions can be computed for general coefficient matrices directly for any basis also performing the expansion in the dimensional parameter in case it is expressible in terms of indefinite nested product-sum expressions. This structural result is based on new results of our difference ring theory. In the cases discussed we deal with iterative sum- and integral-solutions over general alphabets. The final results are expressed in terms of special sums, forming quasi-shuffle algebras, such as nested harmonic sums, generalized harmonic sums, and nested binomially weighted (cyclotomic) sums. Analytic continuations to complex values of N are possible through the recursion relations obeyed by these quantities and their analytic asymptotic expansions. The latter lead to a host of new constants beyond the multiple zeta values, the infinite generalized harmonic and cyclotomic sums in the case of V-topologies.

These observations will permit the instrumental polarization to be calibrated. The instrumental polarization must be determined to a high precision in order to vectoriallly remove it from HSP polarization observations to determine the actual astronomical polarization. Final run of proposal will look at one of 2 possible stars previously observed to get another look at the throughput. Revision History: Mark H.

  7. On the finite Fourier transforms of functions with infinite discontinuities

    2002-01-01

    Full Text Available The introductory part of the paper is provided to give a brief review of the stability theory of a matrix pencil for discrete linear time-invariant singular control systems, based on the causal relationship between Jordan's theorem from the theory of Fourier series and Laurent's theorem from the calculus of residues. The main part is concerned with the theory of the integral transforms, which has proved to be a powerful tool in the control systems theory. On the basis of a newly defined notion of the total value of improper integrals, throughout the main part of the paper, an attempt has been made to present the global theory of the integral transforms, which are slightly more general with respect to the Laplace and Fourier transforms. The paper ends with examples by which the results of the theory are verified.

    2010-11-15

    We perform the integration of all iterated singly-unresolved subtraction terms over the two-particle factorized phase space. We also sum over the unresolved parton flavours. The final result can be written as a convolution (in colour space) of the Born cross section and an insertion operator. We spell out the insertion operator in terms of 24 basic integrals that are defined explicitly. We compute the coefficients of the Laurent-expansion of these integrals in two different ways, with the method of Mellin-Barnes representations and sector decomposition. Finally, we present the Laurentexpansion of the full insertion operator for the specific examples of electron-positron annihilation into two and three jets. (orig.)

    2012-02-01

    A big class of Feynman integrals, in particular, the coefficients of their Laurent series expansion w.r.t. the dimension parameter ε can be transformed to multi-sums over hypergeometric terms and harmonic sums. In this article, we present a general summation method based on difference fields that simplifies these multi--sums by transforming them from inside to outside to representations in terms of indefinite nested sums and products. In particular, we present techniques that assist in the task to simplify huge expressions of such multi-sums in a completely automatic fashion. The ideas are illustrated on new calculations coming from 3-loop topologies of gluonic massive operator matrix elements containing two fermion lines, which contribute to the transition matrix elements in the variable flavor scheme.

    Full Text Available The Second Congo War in the Democratic Republic of the Congo (The Congo has been the largest humanitarian crisis in the last decade. Over five million people have died, and millions more have been displaced. During the conflict, the ostensibly neutral United States subtly sided with Rwanda and Uganda at the expense of the Congolese President Laurent Kabila. I test whether the media indexed their coverage to Washington policy. However, I expand my analysis to compare coverage leading in British and French newspapers as well. After careful examination, I discover that there is no significant difference in reporting. However, the real question of bias and framing includes issues of neutrality, the prominence of linking the Second Congo War with the 1994 Rwandan genocide, and the persistent underreporting of economic exploitation that underpinned the violence.

  19. Return on experience on nuclear accidents

    2015-09-01

    After a presentation of the International Nuclear and radiological Events Scale (INES scale), of its levels and criteria, this article proposes brief recalls of some nuclear accidents which occurred in nuclear reactors: Chalk River in Canada (1952), Windscale in England (1957), the universal Canadian reactor (NRU in 1958), the SL1 reactor of the Idaho National Laboratory in the USA (1961), the Swiss Lucens reactor (1969), Saint-Laurent des Eaux in France (1969 and 1980). More detailed descriptions are then given for the Three Mile Island accident in 1979, the Chernobyl accident in 1986, and the Fukushima accident in 2011. The main causes of these accidents are identified: loss of control of chain reaction, cooling defect on a stopped reactor, cooling defect on an operated reactor. Some lessons are drawn from these facts, and some characteristics of the EPR are outlined with respect with problems encountered in these accidents

    The guiding principle of this presentation of ``Classical Complex Analysis'' is to proceed as quickly as possible to the central results while using a small number of notions and concepts from other fields. Thus the prerequisites for understanding this book are minimal; only elementary facts of calculus and algebra are required. The first four chapters cover the essential core of complex analysis: - differentiation in C (including elementary facts about conformal mappings) - integration in C (including complex line integrals, Cauchy's Integral Theorem, and the Integral Formulas) - sequences and series of analytic functions, (isolated) singularities, Laurent series, calculus of residues - construction of analytic functions: the gamma function, Weierstrass' Factorization Theorem, Mittag-Leffler Partial Fraction Decomposition, and -as a particular highlight- the Riemann Mapping Theorem, which characterizes the simply connected domains in C. Further topics included are: - the theory of elliptic functions based on...

    R and D has decided to develop an Eulerian diffusion model easy to adapt to meteorological data coming from different sources: for instance the ARPEGE code of Meteo-France or the MERCURE code of EDF. We demand this in order to be able to apply the code in independent cases: a posteriori studies of accidental releases from nuclear power plants ar large or medium scale, simulation of urban pollution episodes within the ''Reactive Atmospheric Flows'' research project. For simplicity reasons, the numerical formulation of our code is the same as the one used in Meteo-France's MEDIA model. The numerical tests presented in this report show the good performance of those schemes. In order to illustrate the method by a concrete example a fictitious release from Saint-Laurent has been simulated at national scale: the results of this simulation agree quite well with those of the trajectory model DIFTRA.

  8. Fuchsia. A tool for reducing differential equations for Feynman master integral to epsilon form

    International Nuclear Information System (INIS)

    Gituliar, Oleksandr; Magerya, Vitaly

    2017-01-01

    We present Fuchsia - an implementation of the Lee algorithm, which for a given system of ordinary differential equations with rational coefficients ∂ x f(x,ε)=A(x,ε)f(x,ε) finds a basis transformation T(x,ε), i.e., f(x,ε)=T(x,ε)g(x,ε), such that the system turns into the epsilon form: ∂ x g(x,ε)=εS(x)g(x,ε), where S(x) is a Fuchsian matrix. A system of this form can be trivially solved in terms of polylogarithms as a Laurent series in the dimensional regulator ε. That makes the construction of the transformation T(x,ε) crucial for obtaining solutions of the initial system. In principle, Fuchsia can deal with any regular systems, however its primary task is to reduce differential equations for Feynman master integrals. It ensures that solutions contain only regular singularities due to the properties of Feynman integrals.

  9. Recent symbolic summation methods to solve coupled systems of differential and difference equations

    International Nuclear Information System (INIS)

    Schneider, Carsten; Bluemlein, Johannes; Freitas, Abilio de

    2014-07-01

    We outline a new algorithm to solve coupled systems of differential equations in one continuous variable x (resp. coupled difference equations in one discrete variable N) depending on a small parameter ε: given such a system and given sufficiently many initial values, we can determine the first coefficients of the Laurent-series solutions in ε if they are expressible in terms of indefinite nested sums and products. This systematic approach is based on symbolic summation algorithms in the context of difference rings/fields and uncoupling algorithms. The proposed method gives rise to new interesting applications in connection with integration by parts (IBP) methods. As an illustrative example, we will demonstrate how one can calculate the ε-expansion of a ladder graph with 6 massive fermion lines.

  10. Mathematical aspects of Feynman integrals

    International Nuclear Information System (INIS)

    Bogner, Christian

    2009-08-01

    In the present dissertation we consider Feynman integrals in the framework of dimensional regularization. As all such integrals can be expressed in terms of scalar integrals, we focus on this latter kind of integrals in their Feynman parametric representation and study their mathematical properties, partially applying graph theory, algebraic geometry and number theory. The three main topics are the graph theoretic properties of the Symanzik polynomials, the termination of the sector decomposition algorithm of Binoth and Heinrich and the arithmetic nature of the Laurent coefficients of Feynman integrals. The integrand of an arbitrary dimensionally regularised, scalar Feynman integral can be expressed in terms of the two well-known Symanzik polynomials. We give a detailed review on the graph theoretic properties of these polynomials. Due to the matrix-tree-theorem the first of these polynomials can be constructed from the determinant of a minor of the generic Laplacian matrix of a graph. By use of a generalization of this theorem, the all-minors-matrix-tree theorem, we derive a new relation which furthermore relates the second Symanzik polynomial to the Laplacian matrix of a graph. Starting from the Feynman parametric parameterization, the sector decomposition algorithm of Binoth and Heinrich serves for the numerical evaluation of the Laurent coefficients of an arbitrary Feynman integral in the Euclidean momentum region. This widely used algorithm contains an iterated step, consisting of an appropriate decomposition of the domain of integration and the deformation of the resulting pieces. This procedure leads to a disentanglement of the overlapping singularities of the integral. By giving a counter-example we exhibit the problem, that this iterative step of the algorithm does not terminate for every possible case. We solve this problem by presenting an appropriate extension of the algorithm, which is guaranteed to terminate. This is achieved by mapping the iterative

    Beretta, Marco

    2012-01-01

    This paper presents two hitherto unknown drawings by Marie-Anne-Pierrette Lavoisier dating to the early 1790s that illustrate the experiments on respiration and transpiration of her husband Antoine-Laurent Lavoisier and his assistant Armand Séguin. These works may be associated with the well-known sepia drawings that were published for the first time by Edouard Grimaux in 1888. Details contained in these newly discovered drawings by M.me Lavoisier provide fresh evidence as to the nature and aims of Lavoisier's innovative experiments. As we will show, these drawings were intended to illustrate the collection of papers on respiration being prepared by Lavoisier for his Mémoires de physique et de chimie (1792-1805).

This article analyses how European academies contributed to shape the idea of scientific truth in the second half of XVIIIth century. It focuses on the role played by academics in disseminating certain theories and censoring other ones, destined to be considered as false beliefs. Two theories stand out: mesmerism, connected to the Viennese physician Franz Anton Mesmer, and the nouvelle chimie, connected to the chemical revolution implemented by Antoine-Laurent Lavoisier. The criteria of scientific truth elaborated by academics influenced the reception of the two theories in France and Italy: mesmerism was received with popular enthusiasm while was condemned by the academic world as the invention of a charlatan; on the opposite, Lavoisier’s chemistry, after initial resistances, was accepted at the institutional level.

    If we define scientific revolutions as changes of scientists' ontologies, types of causal explanation, and paradigmatic types of methods and instruments, Antoine-Laurent Lavoisier's contribution to chemistry did not amount to a scientific revolution. Contrary to the received view that Lavoisier initiated a "chemical revolution," which is accepted by Chang and Kusch, I argue that Lavoisier shared with the phlogistonists their "flat ontology" of chemical substance, established decades before the 1770s, their types of explaining chemical transformation, and their quantitative methods. Based on my historical reconstruction, I criticize Chang's argument that the late eighteenth-century phlogistic systems and Lavoisier's system belonged to two different theoretical traditions. As a consequence, I also question Chang's argument that the acceptance of Lavoisier's system can be explained in terms of dominance of "compositionism" over "principlism."

The article has a general perception with the aim of emphasizing, from the individual poetics, the process of symbolization of the “I” in the Mexican narrative from the beginnings of the 21st century, that as cultural phenomenon unfolds in the borders of literariness and society. The theoretical perspective that encourages the analysis starts off, mainly, from the proposal of the North American psychologist Kenneth Gergen, the sociologist Zigmunt Bauman and the mythocritic proposal of Gilbert Durand.

  20. Learned value magnifies salience-based attentional capture.

    Science.gov (United States)

    Anderson, Brian A; Laurent, Patryk A; Yantis, Steven

    2011-01-01

    Visual attention is captured by physically salient stimuli (termed salience-based attentional capture), and by otherwise task-irrelevant stimuli that contain goal-related features (termed contingent attentional capture). Recently, we reported that physically nonsalient stimuli associated with value through reward learning also capture attention involuntarily (Anderson, Laurent, & Yantis, PNAS, 2011). Although it is known that physical salience and goal-relatedness both influence attentional priority, it is unknown whether or how attentional capture by a salient stimulus is modulated by its associated value. Here we show that a physically salient, task-irrelevant distractor previously associated with a large reward slows visual search more than an equally salient distractor previously associated with a smaller reward. This magnification of salience-based attentional capture by learned value extinguishes over several hundred trials. These findings reveal a broad influence of learned value on involuntary attentional capture.

    Full Text Available This paper argues against the suggestion that governments should push for gender equality more aggressively in order to raise fertility. The paper presents a threefold "no" to this proposal. It takes issue with the goal of raising fertility, arguing that the claims that fertility must be increased are based on myths. It rejects a more aggressive pursuit of gender equality for demographic purposes, maintaining that this method preserves inequality. It warns against using gender equality for fertility purposes, stating that this narrows the realm of gender equality. The paper is based on a debate held at the Max Planck Institute for Demographic Research in Rostock, at which the author was asked to argue against the gender equality-fertility proposal. The other participants in the debate were Laurent Toulemon ("yes", Dimiter Philipov ("no", and Livia Oláh ("yes".

    Full Text Available This paper is based on my contribution to a debate, organized by MPIDR, on the question displayed in the title above. I was asked to present arguments for the "yes"-response (together with Laurent Toulemon, and arguing against the "no"-side represented by Gerda Neyer and Dimiter Philipov. As pointed out in the paper, the most important theoretical reasoning relevant for this question is the gender equity theory. A number of studies provide sound empirical support to it, as discussed in the paper in details, and thereby also a rationale for a positive impact of increased gender equality on fertility. As the dual-earner family is here to stay, and given the well-known negative consequences of long-term very low fertility for a society, pushing for gender equality seems to be a reasonable strategy to be considered aiming for sustainable societal development.

    Harmonic distributions on the two sphere are developed and their relation with the complex plane ones is established. the basic harmonic distributions are shown to obey the Cauchy integration rules. Local Cartan tensors on S 2 are introduced. They are analytic functions satisfying a harmonic analyticity condition. Their Laurent expansion is examined and the connection with the complex plane analysis is given. Diff(S 2 ) and its one parameter gauge subgroups are discussed in the harmonic coordinate system. The derivation of the Virasoro algebra from the one parameter subgroups of Diff(S 2 ) is worked out in two special cases (α -- .β ++ = 0). A realization based on Cartan tensors is also given. Finally, we show that there is a 1 : 1 correspondence between the (2,0) supersymmetry on S 2 and the hypermultiplet duality of Galperin et al. (author). 19 refs

    This document presents the International Nuclear Event Scale (INES) which has been created to classify nuclear and radiological events in terms of severity. This scale comprises eight levels from 0 to 7, from a slight but noticeable shift with respect to nominal operation to a major accident. Criteria used for incident and accident classification are indicated; they are based on consequences outside the site, consequences within the site, degradation of in-depth defence. The benefit and weaknesses of this scale are briefly indicated. The major concerned actors are the IAEA, the NEA and the ASN. Some key figures are given (number of declared events and incidents), and a ranking of the main nuclear events is proposed with a brief description of the event: Chernobyl, Fukushima, Kyshtym, Three Mile Island, Sellafield, Tokaimura, Saint-Laurent-des-Eaux. Countries which have adopted INES are indicated, as well as the number of incidents reports in France to the ASN

    Three species of the pagurid hermit crab genus Catapaguroides A. Milne-Edwards & Bouvier, 1892, all from Japanese waters, are reported. Catapaguroides fragilis (Melin, 1939) is redescribed on the basis of the holotype and additional material from southern Japan. Diagnostic characters of this poorly known species are fully assessed. Two new species, C. bythos and C. rubromaculatus, are described and illustrated on the basis of material from upper bathyal depths off the Ryukyu Islands. Catapaguroides rubromaculatus n. sp. resembles C. fragilis and C. hirsutus Komai & Rahayu, 2013, but the characteristic shape of the ocular peduncle and the elongate male right sexual tube with an anteriorly directed distal portion readily separate C. rubromaculatus n. sp. from the latter two congeners. Catapaguroides bythos n. sp. appears close to C. mortenseni de Saint Laurent, 1968 and C. pectinipes (Lewinsohn, 1969), but the different armature of the chelipeds distinguishes C. bythos n. sp. from the latter two allies. Catapaguroides is now represented by 30 species.

    Full Text Available The aim of this study was to characterize the pattern of shell occupation by the hermit crab Isocheles sawayai Forest and Saint-Laurent, 1968, from the Caraguatatuba region. The percentage of shell types that were occupied and the morphometric relationships between hermit crabs and occupied shells were analyzed from systematized collections that were conducted monthly from July 2001 to June 2003. A total of 373 individuals were captured (297 males, 41 non-ovigerous females, 25 ovigerous females and 10 intersexes, occupying 17 species of gastropod shells. Stramonita haemastoma (Linnaeus, 1767 (49.87% was the significantly most occupied species (χ2 = 89.30; P 0.68 and significant (P < 0.05 correlation values, which is an important indication that in this I. sawayai population the animals occupied adequate shells. The high number of occupied shell species and relative plasticity indicated that, for the studied population, occupation is influenced by the shell availability.

    This paper is the result of the study of a squat lobsters collection obtained along the Mauritanian coast, between 91 and 1867 m depth, during the 'MAURIT' surveys carried out in the period from 2007 to 2010. Eumunida bella de Saint Laurent & Macpherson, 1990 (Chirostyloidea) and six species of Munida and Munidopsis (Galatheoidea) are reported in the present work.A new species, Munidopsis anaramosae n. sp. collected off northwestern Banc d'Arguin at 1000-1012 m depth, is described and illustrated. The presence of an eyespine that arises distally from the middle end of the cornea, walking legs merus spinose on dorsal and ventral margins and cheliped merus ventrally unarmed distinguish it from related species. Munida chunii Balss, 1913 is redescribed here and the new records of Munida guineae Miyake & Baba, 1970, M. speciosa von Martens, 1878 and Munidopsis chunii Balss, 1913 extend their geographical distribution northwards, and in the case of the last species, increase its bathymetric range.

    Two-point Feynman parameter integrals, with at most one mass and containing local operator insertions in 4+{epsilon}-dimensional Minkowski space, can be transformed to multi-integrals or multi-sums over hyperexponential and/or hypergeometric functions depending on a discrete parameter n. Given such a specific representation, we utilize an enhanced version of the multivariate Almkvist-Zeilberger algorithm (for multi-integrals) and a common summation framework of the holonomic and difference field approach (for multi-sums) to calculate recurrence relations in n. Finally, solving the recurrence we can decide efficiently if the first coefficients of the Laurent series expansion of a given Feynman integral can be expressed in terms of indefinite nested sums and products; if yes, the all n solution is returned in compact representations, i.e., no algebraic relations exist among the occurring sums and products.

    Saidi, El Hassan; Sedra, Moulay Brahim

    2006-01-01

    We develop the harmonic space method for conifold and use it to study local complex deformations of T*S 3 preserving manifestly SL(2,C) isometry. We derive the perturbative manifestly SL(2,C) invariant partition function Z top of topological string B model on locally deformed conifold. Generic n momentum and winding modes of 2D c=1 noncritical theory are described by highest υ (n,0) and lowest components υ (0,n) of SL(2,C) spin s=n2 multiplets (υ (n-k,k) ), 0= α + and V α - . We also derive a dictionary giving the passage from Laurent (Fourier) analysis on T*S 1 (S 1 ) to the harmonic method on T*S 3 (S 3 ). The manifestly SU(2,C) covariant correlation functions of the S 3 quantum cosmology model of Gukov-Saraikin-Vafa are also studied

  12. Four-gluon scattering at three loops, infrared structure and Regge limit

    CERN Document Server

    Henn, Johannes M.

    2016-01-01

    We compute the three-loop four-gluon scattering amplitude in maximally supersymmetric Yang-Mills theory, including its full color dependence. Our result is the first complete computation of a non-planar four-particle scattering amplitude to three loops in four-dimensional gauge theory and consequently provides highly non-trivial data for the study of non-planar scattering amplitudes. We present the amplitude as a Laurent expansion in the dimensional regulator to finite order, with coefficients composed of harmonic poly-logarithms of uniform transcendental weight, and simple rational prefactors. Our computation provides an independent check of a recent result for three-loop corrections to the soft anomalous dimension matrix that predicts the general infrared singularity structure of massless gauge theory scattering amplitudes. Taking the Regge limit of our result, we determine the three-loop gluon Regge trajectory. We also find agreement with very recent predictions for sub-leading logarithms.

    Gürlebeck, Klaus; Sprößig, Wolfgang

    2016-01-01

    This book presents applications of hypercomplex analysis to boundary value and initial-boundary value problems from various areas of mathematical physics. Given that quaternion and Clifford analysis offer natural and intelligent ways to enter into higher dimensions, it starts with quaternion and Clifford versions of complex function theory including series expansions with Appell polynomials, as well as Taylor and Laurent series. Several necessary function spaces are introduced, and an operator calculus based on modifications of the Dirac, Cauchy-Fueter, and Teodorescu operators and different decompositions of quaternion Hilbert spaces are proved. Finally, hypercomplex Fourier transforms are studied in detail. All this is then applied to first-order partial differential equations such as the Maxwell equations, the Carleman-Bers-Vekua system, the Schrödinger equation, and the Beltrami equation. The higher-order equations start with Riccati-type equations. Further topics include spatial fluid flow problems, ima...

    Full Text Available Species of the parapagurid genus Strobopagurus Lemaitre, 1989 are reviewed based primarily on abundant specimens obtained during French campaigns across the Indo-Pacific region. A new species, S.breviacus, is described. The genus contains two other species, S. gracilipes (A. Milne-Edwards, 1891, the type of the genus, and S.sibogae (de Saint Laurent, 1972. One taxon, Parapagurus kilburni Kensley, 1973, originally described from off eastern Africa, has been found to be a junior synonym of S.sibogae. An updated diagnosis of the genus, and diagnoses and comparative illustrations of all three species, are presented together with a key to aid in their identification. Information on live coloration is provided for S.gracilipes and S. sibogae; live coloration of S. breviacus is not known.

  16. Economic Sociology and Economics of Convention

    DEFF Research Database (Denmark)

    Jagd, Søren

    This paper is part of a larger exploration of the French Economics of Convention tradition. The aim of the paper is to explore potential themes of common interest to economic sociology and Economics of Conventions. The paper is in two parts. First, I summarise the main theoretical features of EC...... the institutional framework of social action. Second, I explore two issues raised by economics of conventions that may be particularly important to consider for economic sociology. The first issue is the explicit exploration of the consequences of a plurality of forms of justification suggested by Luc Boltanski...... and Laurent Thévenot in ‘économie de la grandeur’. This perspective has already been taken up in economic sociology in David Stark’s notion of a ‘Sociology of Worth’. The second issue, recently suggested by André Orléan, is the need to denaturalise economic theory and economic action to demonstrate the social...

  18. An introduction to special functions

    CERN Document Server

    Viola, Carlo

    2016-01-01

    The subjects treated in this book have been especially chosen to represent a bridge connecting the content of a first course on the elementary theory of analytic functions with a rigorous treatment of some of the most important special functions: the Euler gamma function, the Gauss hypergeometric function, and the Kummer confluent hypergeometric function. Such special functions are indispensable tools in "higher calculus" and are frequently encountered in almost all branches of pure and applied mathematics. The only knowledge assumed on the part of the reader is an understanding of basic concepts to the level of an elementary course covering the residue theorem, Cauchy's integral formula, the Taylor and Laurent series expansions, poles and essential singularities, branch points, etc. The book addresses the needs of advanced undergraduate and graduate students in mathematics or physics.

    On the patio of the Main Building, a new garden has been unveiled. Inspired by physicists themselves, the garden uses a clever combination of flower arrangements and slate slabs to create the shape of the CMS particle tracker.   Scribbling, crossing out, and writing over it again. In an age of digital "tablets", scientists have remained faithful to the traditional blackboard... the inspiration for the Slate Garden. Completed just a few days ago on the Main Building patio (Building 500), the garden was designed by landscape architect Laurent Essig – who also created the InGRID installation outside Building 33 – and is the perfect combination of organic and mineral materials. Composed of 100 pieces of slate laid across three concentric circles, the work recalls the elegant lines of the CMS particle tracker. The project was completed thanks to the collaboration of a number of CERN technical services, in particular the Green Spaces Service, the Transport Serv...

  1. On the maximal cut of Feynman integrals and the solution of their differential equations

    Directory of Open Access Journals (Sweden)

    Amedeo Primo

    2017-03-01

    Full Text Available The standard procedure for computing scalar multi-loop Feynman integrals consists in reducing them to a basis of so-called master integrals, derive differential equations in the external invariants satisfied by the latter and, finally, try to solve them as a Laurent series in ϵ=(4−d/2, where d are the space–time dimensions. The differential equations are, in general, coupled and can be solved using Euler's variation of constants, provided that a set of homogeneous solutions is known. Given an arbitrary differential equation of order higher than one, there exists no general method for finding its homogeneous solutions. In this paper we show that the maximal cut of the integrals under consideration provides one set of homogeneous solutions, simplifying substantially the solution of the differential equations.

  4. How to integrate divergent integrals: a pure numerical approach to complex loop calculations

    International Nuclear Information System (INIS)

    Caravaglios, F.

    2000-01-01

    Loop calculations involve the evaluation of divergent integrals. Usually [G. 't Hooft, M. Veltman, Nucl. Phys. B 44 (1972) 189] one computes them in a number of dimensions different than four where the integral is convergent and then one performs the analytical continuation and considers the Laurent expansion in powers of ε=n-4. In this paper we discuss a method to extract directly all coefficients of this expansion by means of concrete and well defined integrals in a five-dimensional space. We by-pass the formal and symbolic procedure of analytic continuation; instead we can numerically compute the integrals to extract directly both the coefficient of the pole 1/ε and the finite part

  5. Q-systems as cluster algebras

    Kedem, Rinat

    2008-01-01

    Q-systems first appeared in the analysis of the Bethe equations for the XXX model and generalized Heisenberg spin chains (Kirillov and Reshetikhin 1987 Zap. Nauchn. Sem. Leningr. Otd. Mat. Inst. Steklov. 160 211-21, 301). Such systems are known to exist for any simple Lie algebra and many other Kac-Moody algebras. We formulate the Q-system associated with any simple, simply-laced Lie algebras g in the language of cluster algebras (Fomin and Zelevinsky 2002 J. Am. Math. Soc. 15 497-529), and discuss the relation of the polynomiality property of the solutions of the Q-system in the initial variables, which follows from the representation-theoretical interpretation, to the Laurent phenomenon in cluster algebras (Fomin and Zelevinsky 2002 Adv. Appl. Math. 28 119-44)

    2015-01-01

    We present methods to compute higher orders in the threshold expansion for the one-loop production of a Higgs boson in association with two partons at hadron colliders. This process contributes to the N$^3$LO Higgs production cross section beyond the soft-virtual approximation. We use reverse unitarity to expand the phase-space integrals in the small kinematic parameters and to reduce the coefficients of the expansion to a small set of master integrals. We describe two methods for the calculation of the master integrals. The first was introduced for the calculation of the soft triple-real radiation relevant to N$^3$LO Higgs production. The second uses a particular factorization of the three body phase-space measure and the knowledge of the scaling properties of the integral itself. Our result is presented as a Laurent expansion in the dimensional regulator, although some of the master integrals are computed to all orders in this parameter.

However, upon the grounds of the narrative plot, this path is triangular in shape, made up by three points on the map (Troy, Carthage and Laurente which are, respectively, the starting point of his exile, a deviation from it, and his arrival. This triangle, which is rele-vant from the point of view of the interpre-tation, and which was brought about by war, love and power, is expressed within a symbolic geometry, adapted to a tri-functional scheme of the judgement of Paris, as a structure connected with the project of rewriting the middle Ages.

    Padhan, Dola Gobinda; Majhi, Somanath

    2013-03-01

    A new control structure with a tuning method to design a PID load frequency controller for power systems is presented. Initially, the controller is designed for single area power system, then it is extended to multi-area case. The controller parameters are obtained by expanding controller transfer function using Laurent series. Relay based identification technique is adopted to estimate power system dynamics. Robustness studies on stability and performance are provided, with respect to uncertainties in the plant parameters. The proposed scheme ensures that overall system remains asymptotically stable for all bounded uncertainties and for system oscillations. Simulation results show the feasibility of the approach and the proposed method improves the load disturbance rejection performance significantly even in the presence of the uncertainties in plant parameters.

    Are reported three experiments carried out in order to fight erosion-corrosion by a pH analysis on the heat exchangers of the plant Saint-Laurent-des-Eaux A, on the low pressure reheaters of conventional flame plants and on the reheater-separator vessels of pressurized water reactors (PWR). The utilization of certain amines, other than ammonia (morpholine and cyclohexylamine) may lead only to some limited improvements due to the thermal decomposition of the reagents and due to the subsequent effects they may have on the chemical characteristics of the water and on the condensate treatments. The solutions related to the chemistry modifications of the water in order to fight erosion-corrosion phenomena are in fact a palliative to conceptional errors which can be useful whenever it is impossible to do otherwise [fr

  18. Mathematical aspects of Feynman integrals

    Energy Technology Data Exchange (ETDEWEB)

    Bogner, Christian

    2009-08-15

    In the present dissertation we consider Feynman integrals in the framework of dimensional regularization. As all such integrals can be expressed in terms of scalar integrals, we focus on this latter kind of integrals in their Feynman parametric representation and study their mathematical properties, partially applying graph theory, algebraic geometry and number theory. The three main topics are the graph theoretic properties of the Symanzik polynomials, the termination of the sector decomposition algorithm of Binoth and Heinrich and the arithmetic nature of the Laurent coefficients of Feynman integrals. The integrand of an arbitrary dimensionally regularised, scalar Feynman integral can be expressed in terms of the two well-known Symanzik polynomials. We give a detailed review on the graph theoretic properties of these polynomials. Due to the matrix-tree-theorem the first of these polynomials can be constructed from the determinant of a minor of the generic Laplacian matrix of a graph. By use of a generalization of this theorem, the all-minors-matrix-tree theorem, we derive a new relation which furthermore relates the second Symanzik polynomial to the Laplacian matrix of a graph. Starting from the Feynman parametric parameterization, the sector decomposition algorithm of Binoth and Heinrich serves for the numerical evaluation of the Laurent coefficients of an arbitrary Feynman integral in the Euclidean momentum region. This widely used algorithm contains an iterated step, consisting of an appropriate decomposition of the domain of integration and the deformation of the resulting pieces. This procedure leads to a disentanglement of the overlapping singularities of the integral. By giving a counter-example we exhibit the problem, that this iterative step of the algorithm does not terminate for every possible case. We solve this problem by presenting an appropriate extension of the algorithm, which is guaranteed to terminate. This is achieved by mapping the iterative

  19. On Minimal Realizations and Minimal Partial Realizations of Linear Time-Invariant Systems Subject to Point Incommensurate Delays

    2008-01-01

    Full Text Available This paper investigates key aspects of realization and partial realization theories for linear time-invariant systems being subject to a set of incommensurate internal and external point delays. The results are obtained based on the use of formal Laurent expansions whose coefficients are polynomial matrices of appropriate orders and which are also appropriately related to truncated and infinite block Hankel matrices. The above-mentioned polynomial matrices arise in a natural way from the transcendent equations associated with the delayed dynamics. The results are linked to the properties of controllability and observability of dynamic systems. Some related overview is given related to robustness concerned with keeping the realization properties under mismatching between a current transfer matrix and a nominal one.

    Full Text Available This paper is part of my doctoral thesis project named Non-hegemonic sexual identities in the Argentine cinema: confrontation between psychoanalysis, gender studies, and hermeneutics. The aim of this research advance is to discuss some hypotheses that are supported by a large part of the psychoanalysis of Lacanian orientation —being J-A. Miller and Eric Laurent their main exponents— in relation to the inexistence of the Other, the fall of the father, and the master signifiers —those commonly utilized to explain diverse symptoms and social problems—. In the light of claims that various sexual minorities carry out in our contemporaneity, and taking some references from Judith Butler and Michel Foucault, the purpose of this paper is to question such hypotheses in order to expand the scope of analysis in this regard.

  3. Numerical simulation of spray coalescence in an Eulerian framework: Direct quadrature method of moments and multi-fluid method

    Fox, R. O.; Laurent, F.; Massot, M.

    2008-03-01

    The scope of the present study is Eulerian modeling and simulation of polydisperse liquid sprays undergoing droplet coalescence and evaporation. The fundamental mathematical description is the Williams spray equation governing the joint number density function f(v,u;x,t) of droplet volume and velocity. Eulerian multi-fluid models have already been rigorously derived from this equation in Laurent et al. [F. Laurent, M. Massot, P. Villedieu, Eulerian multi-fluid modeling for the numerical simulation of coalescence in polydisperse dense liquid sprays, J. Comput. Phys. 194 (2004) 505-543]. The first key feature of the paper is the application of direct quadrature method of moments (DQMOM) introduced by Marchisio and Fox [D.L. Marchisio, R.O. Fox, Solution of population balance equations using the direct quadrature method of moments, J. Aerosol Sci. 36 (2005) 43-73] to the Williams spray equation. Both the multi-fluid method and DQMOM yield systems of Eulerian conservation equations with complicated interaction terms representing coalescence. In order to focus on the difficulties associated with treating size-dependent coalescence and to avoid numerical uncertainty issues associated with two-way coupling, only one-way coupling between the droplets and a given gas velocity field is considered. In order to validate and compare these approaches, the chosen configuration is a self-similar 2D axisymmetrical decelerating nozzle with sprays having various size distributions, ranging from smooth ones up to Dirac delta functions. The second key feature of the paper is a thorough comparison of the two approaches for various test-cases to a reference solution obtained through a classical stochastic Lagrangian solver. Both Eulerian models prove to describe adequately spray coalescence and yield a very interesting alternative to the Lagrangian solver. The third key point of the study is a detailed description of the limitations associated with each method, thus giving criteria for

    In the framework of the development of a probabilistic safety project on site (notion of living PSA), Saint Laurent des Eaux NPP implements a specific EDF reliability database. The main goals of this project at Saint Laurent des Eaux are: to expand risk analysis and to constitute an effective local basis of thinking about operating safety by requiring the participation of all departments of a power plant: analysis of all potential operating transients, unavailability consequences... that means to go further than a simple culture of applying operating rules; to involve nuclear power plant operators in experience feedback and its analysis, especially by following up behaviour of components and of safety functions; to allow plant safety managers to outline their decisions facing safety authorities for notwithstanding, preventive maintenance programme, operating incident evaluation. To hit these goals requires feedback data, tools, techniques and development of skills. The first step is to obtain specific reliability data on the site. Raw data come from plant maintenance management system which processes all maintenance activities and keeps in memory all the records of component failures and maintenance activities. Plant specific reliability data are estimated with a Bayesian model which combines these validated raw data with corporate generic data. This approach allow to provide reliability data for main components modelled in PSA, to check the consistency of the maintenance program (RCM), to verify hypothesis made at the design about component reliability. A number of studies, related to components reliability as well as decision making process of specific incident risk evaluation have been carried out. This paper provides also an overview of the process management set up on site from raw database to specific reliability database in compliance with established corporate objectives.

    Full Text Available La question des rapports du sujet et de l’art en littérature, loin de se limiter à des enjeux d’ordre thématique, s’étend également à la façon dont le sujet est affecté par le croisement des pratiques d’écriture avec d’autres pratiques artistiques. Cette étude se propose de montrer comment le travail réalisé par Olivia Rosenthal autour de Ils ne sont pour rien dans mes larmes met en relation de façon originale les deux aspects de cette question dans la mise en place de dispositifs expérimentaux conduisant à une extension de la pratique littéraire hors du livre. Cette pratique est ici interrogée à travers une mise en regard du texte Les Larmes avec sa mise en performance et son adaptation cinématographique en collaboration avec Laurent Larivière. Ces différentes déclinaisons du dispositif littéraire ne soulignent pas seulement l’intermodalité des pratiques artistiques mais, en mettant le sujet au centre du dispositif, elles rappellent également que le dialogue entre ces pratiques possède un enjeu humain : celui de la diversification des accès que le sujet peut avoir à la compréhension des autres et de lui-même.The question of the relationship between the subject and art in literature, far from being limited to stakes of a thematic nature, also extens to the way in which the subject is affected by the intersection of writing practices with other artistic practices. This study aims to show how the work done by Olivia Rosenthal around Ils ne sont pour rien dans mes larmes originally connects the two aspects of this issue through the development of experimental devices that lead to an extension of the literary practice beyond the book. This practice is examined here through a comparison of the text Les Larmes with the performance and the film by the same name made in collaboration with Laurent Larivière. These different versions of the literary device not only highlight intermodal artistic practices, but

  7. Picard-Fuchs equations of dimensionally regulated Feynman integrals

    International Nuclear Information System (INIS)

    Zayadeh, Raphael

    2013-12-01

    This thesis is devoted to studying differential equations of Feynman integrals. A Feynman integral depends on a dimension D. For integer values of D it can be written as a projective integral, which is called the Feynman parameter prescription. A major complication arises from the fact that for some values of D the integral can diverge. This problem is solved within dimensional regularization by continuing the integral as a meromorphic function on the complex plane and replacing the ill-defined quantity by a Laurent series in a dimensional regularization parameter. All terms in such a Laurent expansion are periods in the sense of Kontsevich and Zagier. We describe a new method to compute differential equations of Feynman integrals. So far, the standard has been to use integration-by-parts (IBP) identities to obtain coupled systems of linear differential equations for the master integrals. Our method is based on the theory of Picard-Fuchs equations. In the case we are interested in, that of projective and quasiprojective families, a Picard-Fuchs equation can be computed by means of the Griffiths-Dwork reduction. We describe a method that is designed for fixed integer dimension. After a suitable integer shift of dimension we obtain a period of a family of hypersurfaces, hence a Picard-Fuchs equation. This equation is inhomogeneous because the domain of integration has a boundary and we only obtain a relative cycle. As a second step we shift back the dimension using Tarasov's generalized dimensional recurrence relations. Furthermore, we describe a method to directly compute the differential equation for general D without shifting the dimension. This is based on the Griffiths-Dwork reduction. The success of this method depends on the ability to solve large systems of linear equations. We give examples of two and three-loop graphs. Tarasov classifies two-loop two-point functions and we give differential equations for these. For us the most interesting example is the two

  8. Cluster algebras in mathematical physics

    2014-01-01

    This special issue of Journal of Physics A: Mathematical and Theoretical contains reviews and original research articles on cluster algebras and their applications to mathematical physics. Cluster algebras were introduced by S Fomin and A Zelevinsky around 2000 as a tool for studying total positivity and dual canonical bases in Lie theory. Since then the theory has found diverse applications in mathematics and mathematical physics. Cluster algebras are axiomatically defined commutative rings equipped with a distinguished set of generators (cluster variables) subdivided into overlapping subsets (clusters) of the same cardinality subject to certain polynomial relations. A cluster algebra of rank n can be viewed as a subring of the field of rational functions in n variables. Rather than being presented, at the outset, by a complete set of generators and relations, it is constructed from the initial seed via an iterative procedure called mutation producing new seeds successively to generate the whole algebra. A seed consists of an n-tuple of rational functions called cluster variables and an exchange matrix controlling the mutation. Relations of cluster algebra type can be observed in many areas of mathematics (Plücker and Ptolemy relations, Stokes curves and wall-crossing phenomena, Feynman integrals, Somos sequences and Hirota equations to name just a few examples). The cluster variables enjoy a remarkable combinatorial pattern; in particular, they exhibit the Laurent phenomenon: they are expressed as Laurent polynomials rather than more general rational functions in terms of the cluster variables in any seed. These characteristic features are often referred to as the cluster algebra structure. In the last decade, it became apparent that cluster structures are ubiquitous in mathematical physics. Examples include supersymmetric gauge theories, Poisson geometry, integrable systems, statistical mechanics, fusion products in infinite dimensional algebras, dilogarithm

  10. The final cool down

    CERN Multimedia

    Thursday 29th May, the cool-down of the final sector (sector 4-5) of LHC has begun, one week after the start of the cool-down of sector 1-2. It will take five weeks for the sectors to be cooled from room temperature to 5 K and a further two weeks to complete the cool down to 1.9 K and the commissioning of cryogenic instrumentation, as well as to fine tune the cryogenic plants and the cooling loops of cryostats.Nearly a year and half has passed since sector 7-8 was cooled for the first time in January 2007. For Laurent Tavian, AT/CRG Group Leader, reaching the final phase of the cool down is an important milestone, confirming the basic design of the cryogenic system and the ability to operate complete sectors. “All the sectors have to operate at the same time otherwise we cannot inject the beam into the machine. The stability and reliability of the cryogenic system and its utilities are now very important. That will be the new challenge for the coming months,” he explains. The status of the cool down of ...

  11. Revolutionising landscapes: Hydroelectricity and the heavy industrialisation of society and environment in the Comte de Beauharnois, 1927--1948

    Science.gov (United States)

    Pelletier, Louis-Raphael

    This dissertation analyses the rapid industrialisation of the rural Comte de Beauharnois and the adjacent stretch of the Fleuve Saint-Laurent owing to the construction, between 1929 and 1948, of a gigantic canal for hydroelectricity production and navigation by an electricity corporation called the Beauharnois Light Heat and Power (BLH&P). Using principally the archives of the BLH&P---especially its complaints files and its rich photographic record---this thesis argues that this process exemplifies the finance capitalist reorganisation of the society and ecosystems of the Canadian province of Quebec from the 19th century to the Great Depression. In keeping with recent work in environmental history, the transformation of rural landscapes and a river for heavy industry is described as an important dimension of a revolution in modes of production. More specifically, I argue that, in the case under study, the finance-capitalist reorganisation of Quebec revolved around two central and explicit projects, one social and the other environmental: the grouping of most individuals in an industrial working class without control over the means of production and the reorganisation of rural landscapes into reservoirs of modern energy and industrial natural resources.

Wines from Znojmo wine region were represented by varieties of Svatovavřinecké (Saint Laurent, Rulandské modré (Pinot Noir, Zweigeltrebe, Frankovka (Lemberger and Dornfelder. The grapes went through the same way of wine making and after completion of alcoholic fermentation were inoculated with pure culture of lactic acid bacteria Oenococcus oeni. Samples were taken for chemical analysis during biodegradation of acids within the range of 2 to 4 days and they were measured using a device WineScan FT 120. Chemical analysis detected changes in the concentrations of the following parameters: total acidity, lactic, malic, tartaric and citric acids. The total content of acids statistically significantly (P = 0.05 differed only between samples of Svatovavřinecké T 66 and Zweigeltrebe T 2.The differences of average mass concentrations of lactic, malic and citric acids were not statistically relevant. Nevertheless, statistically relevant difference in the concentration of tartaric acid from all other wines was detected in a sample of SV T 66 which also reached the highest average value (5.18 g/l.

    In France, in application of the clean water law from January 3, 1992 and since the decree 95-540 from May 4, 1995, each basic nuclear facility receives a single permission which covers both its water takes and its radioactive and non-radioactive effluents. This decree, initially dedicated to new facilities has been enlarged to all existing installations for which the prefectorial by-laws have reached their date-line. Thus, up to now, five inter-ministerial by-laws have renewed the permissions of water takes and effluents evacuation of the power plants of Saint-Laurent-des-Eaux (Loir-et-Cher), Flamanville (Manche), Paluel (Seine-Maritime), Belleville (Cher) and Saint-Alban (Isere). These by-laws foresee an important abatement of the effluents and concern more particularly the tritium, {sup 14}C, the iodine isotopes and also some other non-radioactive chemical compounds. This document is a compilation of all revised by-laws about effluents and concerning the nuclear power plants listed above. (J.S.)

    The work assigned to me during this summer (from June 19th to August 11th) was in the "Search for Top in TOTEM" project, a CMG project in collaboration with TOTEM, under the supervision of Martijn Mulders and Laurent Forthomme. The goal is to determine physical properties of the top anti top quark pair (tt) created by central exclusive processes, particularly the invariant mass. For that it is necessary to relate the measurements of the reconstructed top pair kinematics in the central detector of CMS with the detected protons in the Roman Pots of TOTEM just outside the interaction site, about 200 m from it. CMS only considers decay products from the proton collision, it does not regard the forward protons that participated in the collision. On the contrary, TOTEM does consider these protons. In this research measurements of both TOTEM and CMS were combined Figure 1 shows a diagram of the production of the top anti top pair from the interaction of the two protons. A central exclusive process occurs when the pr...

  19. Finite difference methods for option pricing under Lévy processes: Wiener-Hopf factorization approach.

    Science.gov (United States)

    Kudryavtsev, Oleg

    2013-01-01

    In the paper, we consider the problem of pricing options in wide classes of Lévy processes. We propose a general approach to the numerical methods based on a finite difference approximation for the generalized Black-Scholes equation. The goal of the paper is to incorporate the Wiener-Hopf factorization into finite difference methods for pricing options in Lévy models with jumps. The method is applicable for pricing barrier and American options. The pricing problem is reduced to the sequence of linear algebraic systems with a dense Toeplitz matrix; then the Wiener-Hopf factorization method is applied. We give an important probabilistic interpretation based on the infinitely divisible distributions theory to the Laurent operators in the correspondent factorization identity. Notice that our algorithm has the same complexity as the ones which use the explicit-implicit scheme, with a tridiagonal matrix. However, our method is more accurate. We support the advantage of the new method in terms of accuracy and convergence by using numerical experiments.

  1. Derivation and application of an analytical rock displacement solution on rectangular cavern wall using the inverse mapping method.

    Directory of Open Access Journals (Sweden)

    Mingzhong Gao

    Full Text Available Rectangular caverns are increasingly used in underground engineering projects, the failure mechanism of rectangular cavern wall rock is significantly different as a result of the cross-sectional shape and variations in wall stress distributions. However, the conventional computational method always results in a long-winded computational process and multiple displacement solutions of internal rectangular wall rock. This paper uses a Laurent series complex method to obtain a mapping function expression based on complex variable function theory and conformal transformation. This method is combined with the Schwarz-Christoffel method to calculate the mapping function coefficient and to determine the rectangular cavern wall rock deformation. With regard to the inverse mapping concept, the mapping relation between the polar coordinate system within plane ς and a corresponding unique plane coordinate point inside the cavern wall rock is discussed. The disadvantage of multiple solutions when mapping from the plane to the polar coordinate system is addressed. This theoretical formula is used to calculate wall rock boundary deformation and displacement field nephograms inside the wall rock for a given cavern height and width. A comparison with ANSYS numerical software results suggests that the theoretical solution and numerical solution exhibit identical trends, thereby demonstrating the method's validity. This method greatly improves the computing accuracy and reduces the difficulty in solving for cavern boundary and internal wall rock displacements. The proposed method provides a theoretical guide for controlling cavern wall rock deformation failure.

    An approximate analysis for buckling of biaxial- and shear-loaded anisotropic panels with centrally located elliptical cutouts is presented in the present paper. The analysis is composed of two parts, a prebuckling analysis and a buckling analysis. The prebuckling solution is determined using Lekhnitskii's complex variable equations of plane elastostatics combined with a Laurent series approximation and a boundary collocation method. The buckling solution is obtained using the principle of minimum potential energy. A by-product of the minimum potential energy equation is an integral equation which is solved using Gaussian quadrature. Comparisons with documented experimental results and finite element analyses indicate that the approximate analysis accurately predicts the buckling loads of square biaxial- and shear-loaded panels having elliptical cutouts with major axes up to sixty percent of the panel width. Results of a parametric study are presented for shear- and compression-loaded rectangular anisotropic panels with elliptical cutouts. The effects of panel aspect ratio, cutout shape, cutout size, cutout orientation, laminate anisotropy, and combined loading on the buckling load are examined.

  4. Safety and radiation protection within the French electronuclear fleet in 2014. The IRSN's opinion

    International Nuclear Information System (INIS)

    2015-11-01

    This annual report concerns the 58 pressurized water reactors of the French electronuclear fleet which are currently being operated. After a presentation of this fleet, and a discussion of the global assessment of safety and radiation protection within this fleet (discussion of the noticed trends), this document first reports the analysis performed by the IRSN of some important events and anomalies which occurred in 2014: the presence of migrating elements in the primary circuit which resulted in the damage fuel assembly sheaths (in Saint-Laurent des Eaux), the spraying of electric equipment due to a water flow from leaky hoppers, and the risk of unavailability of important equipment due to a high temperature in the room of the emergency back-up turbo generator set. The next chapter comments significant evolutions: renewal of the command-control system for the 1300 MWe reactors, risks induced on the Gravelines nuclear plant site by the exploitation of the Dunkirk methane terminal, and internal EDF arbitrages related to declarations regarding events which occurred in Val de Loire nuclear plants. These evolutions illustrate how expertises performed by the IRSN on request by the ASN complement EDF expertises and are a contribution to the improvement of installation safety

    Full Text Available With the conformal mapping function provided by Verruijt, the outland of a noncircular tunnel can be mapped to a circular unit in the complex plane and then spread the analytic function into a Laurent series. The stress unified solution of oval and horseshoe cross section can be determined using Muskhelishvili’s complex variables function method. Subsequently, the solution can be taken into the Griffith strength failure criterion and determine the scale and shape of plastic zone in the tunnel surrounding rock. Aiming at the critical safety thickness between a concealed cave and tunnel in the karst area and determining whether the plastic zone of tunnel surrounding rock is connected with the plastic zone of cave as a judgment standard, the model of critical safety thickness among the concealed caves and tunnels is established. The numerical model is established in comparison with the computing method of rock plate critical safety thickness in actual engineering based on the Doumo tunnel engineering of Shanghai-Kunming (Guizhou segment high-speed railway. The following conclusions can be drawn: the analytical approximation method has less indexes, and the output of this method is approximately close to actual engineering and numerical analysis, in which it is reliable and rational.

    Full Text Available The main objective of the research relates to establish predictable values of causality orientation for types of consumer involvement in product. Beside that, the possible differences in expression of causality orientations and dimension of involvement within different groups of respondents were tested. The assumption is that it is possible to predict some of five types of consumer involvement: pleasure, importance, sign, risk importance, risk probability according to dominant type of causality orientation (autonomy, controlled, impersonal. The research were conducted on a sample of 178 consumers on the territory of Republic of Serbia on different types of sex, ages, married and working status, level of education and purchasing power. The General Causality Orientation Scale (Deci and Ryan,1985 and Profil involvement (Laurent and Kapferer, 1985 were used. Pleasure is the most expressed dimension of involvement. When we are talking about sociodemographic variable and the expression of single dimension involvement, there are differences in sex and education. The degree differences of general causality orientation exist only in sex. As important predictors of involvement type the next causality orientation were separated: autonomy for pleasure, controlled for importance and risk importance and impersonal for risk probability. It is not possible to predict the type of involvement on base of general causality orientation of respondents.

  11. The radioactivity measurement in the Loire catchment basin. Actors, networks, data inventory

    International Nuclear Information System (INIS)

    2008-01-01

    The objective of this report on the Loire watershed was to broaden at all the nuclear installations of the watershed the method of synthesis made for Saint-Laurent-des-Eaux nuclear power plant, by resting on the whole of actors doing the radioactivity measurements in environment. This report shows that these actors are numerous. The measurement plans implemented have for objective to establish the radiological situation of environment, near or not the nuclear facilities, to detect the abnormal increase of radioactivity, to evaluate the exposure of populations to the ambient radioactivity, or to check the conformity of practices (nuclear activities) and products. This assessment enlightens the lack of a real global strategy in the organisation of the radioactivity measurement at the level of the watershed. The inventory of available data for the Loire watershed allowed to show the diversity of measurements realised. The I.R.S.N. is face to a complex situation of data return in the frame of the implementation of an information system of the national network of radioactivity measurement in environment. (N.C.)

    Full Text Available This work aims to investigate the ideological and intertextual parallels between Triumph of the Will, the movie, produced by Leni Riefenstahl and the book Mein Kampf, by Adolf Hitler. Triumph of the Will is the film registry of the National Socialist Party in 1934, at the city of Nuremberg and Mein Kampf was written by Hitler in 1924 while He was in jail; the book aims to guide the members of the Nazi party. For this, the research resumes History by the Nazi’s rise using authors like Elias Canetti (1995 and Hannah Arendt (1989; we also study German film production by Siegrief Kracauer (1988. After, this work investigates the movies made by Riefenstahl from Ray Müller’s documentary (1993, and also by the book from Steven Bach (2008 and Riefenstahl’s autobiography (1991. This research constitutes as metodology the books by Mikhail Bakhtin (2010, Robert Stam (1992 and Jacques Durand (1973, to make the movie’s découpage we use Laurent Jullier and Michel Marie (2009. We separated sixteen movie scenes and they were compared between each other to investigate if the movie was made to be seen by all of the german people, to convince them about the Nazi’s ideal – originally present and described in Mein Kampf.

    Full Text Available In recent years, the importance of wine authenticity specification has significantly influenced the world wine market. Nowadays, the importance of terroir is emphasised worldwide. Also in European countries, where varietal wines are produced predominantly, the wine authenticity is given an increasing attention. Anthocyanin pigments represent an important group of phenolic substances that are used for the evaluation of wine authenticity. In this study, altogether 17 varietal red wines originating from the village Dolní Kounice (wine-growing region Moravia, Czech Republic are evaluated. The evaluation involved three varieties, viz. Blaufränkisch (Lemberger, Saint Laurent and Blauer Portugieser as well as three terroirs named Karlov, Šibeniční vrch and Na Nivách. Anthocyanin pigments in varietal red wines were estimated by means of the HPLC method. Thanks to the application of chemometric methods, it was possible to determine the grapevine variety and to classify red wines on the basis of delphinidin-3-O-glucoside (DpGl, malvidin-3-O-glucoside (MvGl and delphinidin-3-O-acetylglucoside (DpGlAc content. The terroir was discriminated on the basis of DpGl, MvGl and delphinidin-3-O-p-coumarylglucoside (DpGl-Cm content.

    It is well known that oxygen and carbon dioxide are two chemicals which enter the plant metabolism as nutrients. The bases of this nowadays obvious statement were placed in the 18th century by means of the works of ingenious naturalists such as Robert Boyle, Stephen Hales, Joseph Priestley, Jam Ingenhousz, Lazzaro Spallanzani and Theodore De Saussure. Till the end of the 17th century, the atmospheric air was considered as an ineffable spirit, the function of which was of physical nature. Boyle was the first naturalist to admit the possibility that respiration were an exchange of vapours occurring in the blood. Stephen Hales realised that air could be fixed by plants under the influence of solar light. Priestley showed that plants could regenerate the bad air making it breathable. Ingenhousz demonstrated that the green parts of plants performed the complete purification of air only under the influence of the light. Spallanzani discovered that plants respire and guessed that the good air (oxygen) originated from the fixed air (carbon dioxide). Finally, Theodore De Saussure showed that plants were able to adsorb carbon dioxide and to release oxygen in a proportional air. All these discoveries benefited of the results coming from investigations of scholars of the so-called "pneumatic chemistry" (Boyle himself, George Ernst Stahl, Joseph Black, Priestley himself, and many more others. But among all the eminent scientists above mentioned stands out the genius of Antoine Laurent Lavoisier, who revolutionised the chemistry of the 18th century ferrying it towards the modern chemistry.

    Full Text Available This article is part of a study that addresses the emergence of critical consumption in southern Brazil. Contemporarily, critical consumption is understood as a multifaceted phenomenon which means the materialization of moral concepts and worldviews on the basis of critical positions in relation to consumption. This study investigated that phenomenon, based on the consumption practices developed within the solidarity economy. Through the contributions of the pragmatic sociology of Luc Boltanski and Laurent Thevenot (1991, we analyzed the axiological rationality that underlies the actors’ preferences in alternative markets. Based on these assumptions, from a field research conducted at the fair of solidarity economy of Santa Maria, RS, Brazil, we highlight the motivations and justifications that lead to the constitution of an ethics of care, anchored in the bonds of community membership with an emphasis on primary sociabilities considering thechoice of a healthy diet. Thus, in relation to the results of this research, we came across the prevalence of arguments grounded in a moral which privileges the care for the members of the household community. In relation the methodological procedures, we made use of a qualitative approach, and used the techniques of participant observation and semi-structured interviews with people who go to this alternative market.

    Full Text Available In mechanics, the solution of soil stresses and displacements field caused by shallow rectangular jacking pipe construction can be simplified as half-plane problem. Both the boundary conditions of the surface and the cavity boundary must be taken into account. It is the essential prerequisite for mechanical analysis of the pipe jacking with the complex variable theory that the mechanical boundary must be transformed from the half-plane with a rectangle cavity to the concentric ring. According to Riemann’s existence theorem and basic complex variable theory, a conformal mapping function is established. Both sides of boundary conditions equation are developed into Laurent series, and then the coefficients of complex stress function are solved by power series method. The derived solution is applied to an example and a comparison is made using FEM method to show the accuracy of the methods. The result shows the following: (1 the method presented in this paper is applicable to a shallow-buried rectangular tunnel; (2 the complex function method proposed in this paper is characterized by clear steps, fast convergence, and simple operation.

    To compare short tau inversion-recovery (STIR) with another fat saturation method in the assessment of sacroiliac joint inflammation. This prospective cross-sectional study comprised 76 spondyloarthritis (SpA) patients who underwent magnetic resonance imaging of the sacroiliac joints in a 1.5-T scanner, using STIR, spectral attenuated inversion recovery (SPAIR) T2w and spectral presaturation with inversion recovery (SPIR) T1w post-contrast sequences. Two independent readers (R1 and R2) assessed the images using the Spondyloarthritis Research Consortium of Canada (SPARCC) score. We assessed agreement of the SPARCC scores for SPAIR T2w and STIR with that for T1 SPIR post-contrast (reference standard) using the St. Laurent coefficient. We evaluated each sequence using the concordance correlation coefficient (CCC). We observed a strong agreement between STIR and SPAIR T2w sequences. Lin's CCC was 0.94 for R1 and 0.84 for R2 for STIR and 0.94 for R1 and 0.84 for R2 for SPAIR. The interobserver evaluation revealed a good CCC of 0.79 for SPAIR and 0.78 for STIR. STIR technique and SPAIR T2w sequence showed high agreement in the evaluation of sacroiliac joint subchondral bone marrow oedema in patients with SpA. SPAIR T2w may be an alternative to the STIR sequence for this purpose. (orig.)

    During a survey on decapod crustacean fauna of shallow coral reefs and nearby environments in Okinawa Island, Ryukyu Archipelago, Japan, four specimens of a small but distinctive undescribed species of pagurid hermit crab, which could not be referred to any known genus, were collected. The new taxon, Eutrichopagurus shirakawai n. gen., n. sp., is described and illustrated herein. The new genus is characterized by the possession of 11 pairs of deeply quadriserial phyllobranchiate gills, the third maxilliped with well-developed crista dentata and one or two accessory teeth on the ischium, the presence of unpaired left gonopore in the female, the absence of paired first pleopods in the female, and the telson with prominent tuft of setae on the lateral margin of the posterior lobes; the male is unknown at present. It appears close to Trichopagurus de Saint Laurent, 1968, but the deeply quadriserial gills immediately distinguish Eutrichopagurus from Trichopagurus. The new genus is also compared with other genera characterized by the possession of 11 pairs of quadriserial phyllobranchiate gills and the lack of paired first pleopods in females.

    We present methods to compute higher orders in the threshold expansion for the one-loop production of a Higgs boson in association with two partons at hadron colliders. This process contributes to the N{sup 3}LO Higgs production cross section beyond the soft-virtual approximation. We use reverse unitarity to expand the phase-space integrals in the small kinematic parameters and to reduce the coefficients of the expansion to a small set of master integrals. We describe two methods for the calculation of the master integrals. The first was introduced for the calculation of the soft triple-real radiation relevant to N{sup 3}LO Higgs production. The second uses a particular factorization of the three body phase-space measure and the knowledge of the scaling properties of the integral itself. Our result is presented as a Laurent expansion in the dimensional regulator, although some of the master integrals are computed to all orders in this parameter.

    Full Text Available Twenty-five samples of different Slovak wines before and after filtration were analysed in order to determine the content of eight biogenic amines (tryptamine, phenylalanine, putrescine, cadaverine, histamine, tyramine, spermidine and spermine. The method involves extraction of biogenic amines from wine samples with used dansyl chloride. Ultra-high performance liquid chromatography (UHPLC was used for determination of biogenic amines equipped with a Rapid Resolution High Definition (RRHD, DAD detectors and Extend-C18 LC column (50 mm x 3.0 mm ID, 1.8 μm particle size. In this study the highest level of biogenic amine in all wine samples represent tryptamine (TRM with the highest content 170.9±5.3 mg/L in Pinot Blanc wine. Phenylalanine (PHE cadaverine (CAD, histamine (HIS and spermidine (SPD were not detected in all wines; mainly SPD was not detected in 16 wines, HIS not detected in 14 wines, PHE and CAD not detected in 2 wines. Tyramine (TYR, spermine (SPN and putrescine (PUT were detected in all wines, but PUT and SPN in very low concentration. The worst wine samples with high biogenic amine content were Saint Laurent (BF, Pinot Blanc (S and Pinot Noir (AF.

    Anthyllis vulneraria was highlighted here as a Zn-hyperaccumulator for the development of a pilot phytoextraction process in the mine site of Les Avinières in the district of Saint-Laurent-Le-Minier. A. vulneraria appeared to hyperaccumulate the highest concentration of Zn in shoots with a better metal selectivity relative to Cd and Pb than the reference Zn-hyperaccumulator Noccea caerulescens. A bigger biomass production associated to a higher Zn concentration conducted A. vulneraria to the highest total zinc gain per hectare per year. As a legume, A. vulneraria was infected by rhizobia symbionts. Inoculation of A. vulneraria seeds showed a positive impact on Zn hyperaccumulation. A large-scale culture process of symbiotic rhizobia of A. vulneraria was investigated and optimized to allow large-scale inoculation process. Contaminated shoots of A. vulneraria were not considered as wastes and were recovered as Eco-Zn catalyst in particular, examples of organic synthesis, electrophilic aromatic substitution. Eco-Zn catalyst was much more efficient than conventional catalysts and allowed greener chemical processes.

  8. Nonlinearly perturbed semi-Markov processes

    Silvestrov, Dmitrii

    2017-01-01

    The book presents new methods of asymptotic analysis for nonlinearly perturbed semi-Markov processes with a finite phase space. These methods are based on special time-space screening procedures for sequential phase space reduction of semi-Markov processes combined with the systematical use of operational calculus for Laurent asymptotic expansions. Effective recurrent algorithms are composed for getting asymptotic expansions, without and with explicit upper bounds for remainders, for power moments of hitting times, stationary and conditional quasi-stationary distributions for nonlinearly perturbed semi-Markov processes. These results are illustrated by asymptotic expansions for birth-death-type semi-Markov processes, which play an important role in various applications. The book will be a useful contribution to the continuing intensive studies in the area. It is an essential reference for theoretical and applied researchers in the field of stochastic processes and their applications that will cont...

  9. „Why?” Instead of „Whether?” Educational Policy Against Inequality – The Problem of Justification

    Full Text Available The subject of the article is focused on the theoretical basis and the results of critical discourse analysis of educational policy of the European Union concerning educational inequalities. These analyzes were made through the official strategy or recommendation documents (programming documents and expert concerning ed- ucational aspects and are based on interviews with representatives of the EU admin- istration and experts. The starting point for this discussion is not the question about “whether”, as according to the official discourse, one should prevent social inequalities in educational system, but “why” should we counteract them? In conducted analysis, I used the construct of “regimes of justification” (fr. régimes de justification - category developed by Luc Boltanski, Laurent Thevenot and Ève Chiapello. This article’s aim is to identify and reconstruct educational policy discourses present in educational policy, which represent different “regimes of justification” of policies and practices of inclusion and an attempt to consider the consequences of this variety of discourses in the context of well-known and documented in social sciences thesis of the dominance of economic rationality in educational policy.

  11. Line operators in theories of class S, quantized moduli space of flat connections, and Toda field theory

    2015-05-01

    Non-perturbative aspects of N=2 supersymmetric gauge theories of class S are deeply encoded in the algebra of functions on the moduli space M flat of at SL(N)-connections on Riemann surfaces. Expectation values of Wilson and 't Hooft line operators are related to holonomies of flat connections, and expectation values of line operators in the low-energy effective theory are related to Fock-Goncharov coordinates on M flat . Via the decomposition of UV line operators into IR line operators, we determine their noncommutative algebra from the quantization of Fock-Goncharov Laurent polynomials, and find that it coincides with the skein algebra studied in the context of Chern-Simons theory. Another realization of the skein algebra is generated by Verlinde network operators in Toda field theory. Comparing the spectra of these two realizations provides non-trivial support for their equivalence. Our results can be viewed as evidence for the generalization of the AGT correspondence to higher-rank class S theories.

    International Nuclear Information System (INIS)

    2012-01-01

    Analytical chemistry is the branch of science that deals with the determination of the identity and concentration of various elements and compounds in different matrices including living systems. The practice of analytical chemistry as a distinct discipline possibly began in the late eighteenth century with the work of the French chemist Antoine-Laurent Lavoisier and his contemporaries. Further progress was made in the nineteenth century by scientists like Carl Fresenius and Karl Friedrich Mohr. Fresenius developed the qualitative analysis method and it formed the topic of the first textbook of analytical chemistry. He also developed the gravimetric technique. Mohr developed many laboratory analytical procedures and devices. Most of the major advances in analytical chemistry, as in many other branches of science, took place in the twentieth century after the Second World War. The demand for new and increasingly sophisticated analytical techniques for bio-medical, regulatory and strategic requirements, along with the progress in electro-mechanical instrumentation, automation and computerization, has opened up new challenges and opportunities for analytical chemists and allied scientists in the years to come.

Nanotechnology could provide optimal vectors able to protect from degradation therapeutical biomolecules such as proteins, enzymes or specific polypeptides. On the other hand, some proteins can be also used as active ligands to help nanoparticles loaded with chemotherapeutic or other drugs to reach particular sites in the body. The aim of this review is to provide an overall picture of the general aspects of the most successful approaches used to combine proteins with nanosystems. This combination is mainly achieved by absorption, bioconjugation and encapsulation. Interactions of nanoparticles with biomolecules and caveats related to protein denaturation are also pointed out. A clear understanding of nanoparticle-protein interactions could make possible the design of precise and versatile hybrid nanosystems. This could further allow control of their pharmacokinetics as well as activity, and safety.Keywords: nanoparticles, drug delivery, proteins, polypeptides, absorption, bioconjugation, encapsulation

The fact is that both quotations have something in common: a discoursive form which results from an unusual syntax, as if they were already, in a certain sense, „translations”. As if the translators feared—a feature of the translator’s psychology?—not to render their text sufficiently accessible, even when the source text is not intended to be accessible. Hence the painful dilemma of the intentional fallacy (not only of the text to be translated.

    2009-01-01

    We consider the multidimensional aggregation equation u t − ∇· (u∇K * u) = 0 in which the radially symmetric attractive interaction kernel has a mild singularity at the origin (Lipschitz or better). In the case of bounded initial data, finite time singularity has been proved for kernels with a Lipschitz point at the origin (Bertozzi and Laurent 2007 Commun. Math. Sci. 274 717–35), whereas for C 2 kernels there is no finite-time blow-up. We prove, under mild monotonicity assumptions on the kernel K, that the Osgood condition for well-posedness of the ODE characteristics determines global in time well-posedness of the PDE with compactly supported bounded nonnegative initial data. When the Osgood condition is violated, we present a new proof of finite time blow-up that extends previous results, requiring radially symmetric data, to general bounded, compactly supported nonnegative initial data without symmetry. We also present a new analysis of radially symmetric solutions under less strict monotonicity conditions. Finally, we conclude with a discussion of similarity solutions for the case K(x) = |x| and some open problems

    Full Text Available Cet article analyse les limites du naturalisme social que Laurence Kaufman et Laurent Cordonier proposent d’adopter dans cette même revue, en critiquant leur plaidoyer pour l’intégration des savoirs des sciences cognitives et des sciences humaines et sociales. Cette critique repose sur la réfutation de trois idées soutenues par les auteurs : 1 la description scientifique des mécanismes cognitifs élémentaires fournit une explication causale des conduites sociales qui doit se substituer à celles des sciences humaines et sociales ; 2 le recours au naturalisme permet de falsifier les préconceptions que ces dernières continuent à entretenir ; 3 le programme de naturalisation de l’esprit n’implique aucune forme de réductionnisme. Cette triple critique permet de rejeter leur appel en faveur d’un modèle intégré de la conduite humaine, en avançant un constat : dans la mesure où on ne sait pas comment combler le hiatus qui sépare les descriptions détaillées du cerveau au travail de l’explication des conduites des individus et de la manière dont ils en assurent la coordination dans le temps même où ils agissent en commun, les sciences humaines et sociales ont peu de choses à aller glaner du côté des sciences cognitives pour améliorer la manière dont elles analysent l’action. C’est que le travail de celles-ci se situe soit au niveau infra-humain du fonctionnement moléculaire, soit au niveau supra-humain de l’évolution ; et que seules les sciences humaines et sociales placent leurs analyses à un niveau simplement humain, en faisant des individus tels qu’ils vivent ensemble la mesure de toutes les choses qui les concernent.

    The objective of this report on the Loire watershed was to broaden at all the nuclear installations of the watershed the method of synthesis made for Saint-Laurent-des-Eaux nuclear power plant, by resting on the whole of actors doing the radioactivity measurements in environment. This report shows that these actors are numerous. The measurement plans implemented have for objective to establish the radiological situation of environment, near or not the nuclear facilities, to detect the abnormal increase of radioactivity, to evaluate the exposure of populations to the ambient radioactivity, or to check the conformity of practices (nuclear activities) and products. This assessment enlightens the lack of a real global strategy in the organisation of the radioactivity measurement at the level of the watershed. The inventory of available data for the Loire watershed allowed to show the diversity of measurements realised. The I.R.S.N. is face to a complex situation of data return in the frame of the implementation of an information system of the national network of radioactivity measurement in environment. (N.C.)

  4. Research on reliability management systems for Nuclear Power Plant

    2000-01-01

    Investigation on a reliability management system for Nuclear Power Plants (NPPs) has been performed on national and international archived documents as well as on current status of studies at Idaho National Engineering and Environmental Laboratory (INEEL), US NPPs (McGuire, Seabrook), a French NPP (St. Laurent-des-Eaux), Japan Atomic Energy Research Institute (JAERI), Central Research Institute of Electric Power Industries (CRIEPI), and power plant manufacturers in Japan. As a result of the investigation, the following points were identified: (i) A reliability management system is composed of a maintenance management system to inclusively manage maintenance data, and an anomalies information and reliability data management system to extract data from maintenance results stored in the maintenance management system and construct a reliability database. (ii) The maintenance management system, which is widely-used among NPPs in the US and Europe, is an indispensable system for the increase of maintenance reliability. (iii) Maintenance management methods utilizing reliability data like Reliability Centered Maintenance are applied for NPP maintenance in the US and Europe, and contributing to cost saving. Maintenance templates are effective in the application process. In addition, the following points were proposed on the design of the system: (i) A detailed database on specifications of facilities and components is necessary for the effective use of the system. (ii) A demand database is indispensable for the application of the methods. (iii) Full-time database managers are important to maintain the quality of the reliability data. (author)

  5. Some integrable maps and their Hirota bilinear forms

    Hone, A. N. W.; Kouloukas, T. E.; Quispel, G. R. W.

    2018-01-01

    We introduce a two-parameter family of birational maps, which reduces to a family previously found by Demskoi, Tran, van der Kamp and Quispel (DTKQ) when one of the parameters is set to zero. The study of the singularity confinement pattern for these maps leads to the introduction of a tau function satisfying a homogeneous recurrence which has the Laurent property, and the tropical (or ultradiscrete) analogue of this homogeneous recurrence confirms the quadratic degree growth found empirically by Demskoi et al. We prove that the tau function also satisfies two different bilinear equations, each of which is a reduction of the Hirota–Miwa equation (also known as the discrete KP equation, or the octahedron recurrence). Furthermore, these bilinear equations are related to reductions of particular two-dimensional integrable lattice equations, of discrete KdV or discrete Toda type. These connections, as well as the cluster algebra structure of the bilinear equations, allow a direct construction of Poisson brackets, Lax pairs and first integrals for the birational maps. As a consequence of the latter results, we show how each member of the family can be lifted to a system that is integrable in the Liouville sense, clarifying observations made previously in the original DTKQ case.

  12. Cotangent Models for Integrable Systems

    Kiesenhofer, Anna; Miranda, Eva

    2017-03-01

    We associate cotangent models to a neighbourhood of a Liouville torus in symplectic and Poisson manifolds focusing on b-Poisson/ b-symplectic manifolds. The semilocal equivalence with such models uses the corresponding action-angle theorems in these settings: the theorem of Liouville-Mineur-Arnold for symplectic manifolds and an action-angle theorem for regular Liouville tori in Poisson manifolds (Laurent- Gengoux et al., IntMath Res Notices IMRN 8: 1839-1869, 2011). Our models comprise regular Liouville tori of Poisson manifolds but also consider the Liouville tori on the singular locus of a b-Poisson manifold. For this latter class of Poisson structures we define a twisted cotangent model. The equivalence with this twisted cotangent model is given by an action-angle theorem recently proved by the authors and Scott (Math. Pures Appl. (9) 105(1):66-85, 2016). This viewpoint of cotangent models provides a new machinery to construct examples of integrable systems, which are especially valuable in the b-symplectic case where not many sources of examples are known. At the end of the paper we introduce non-degenerate singularities as lifted cotangent models on b-symplectic manifolds and discuss some generalizations of these models to general Poisson manifolds.

  13. The din of gunfire: Rethinking the role of sound in World War II newsreels

    Full Text Available French film historian Laurent Véray has famously called World War I ‘the first media war of the twentieth century’. Newsreels, which first appeared in 1910, brought the war to movie theaters across Europe and the U.S., screening combat for those on the ‘home front’. However, while the audience could see the action it could not hear it – sometimes only live music would accompany the movements of the troops. The arrival of sound newsreels in 1929 radically transformed moviegoers’ experiences of the news, and, by necessity, of armed conflict. Drawing on examples of World War II newsreels from British Pathé’s archive that was recently made available online, this article seeks to delineate the logic governing the combination of voice-over commentary, music, sound effects, and field-recorded sound, and argues that it can be traced directly to the treatment of sound in the ‘Great War’ fiction films of the preceding decade.

    According to the United Nations Convention on the Law of the Sea (UNCLOS), individual nations? sovereign rights extend to 200 nautical miles (n.mi.) (370 km) offshore or to a maritime boundary in an area called the continental shelf. These rights include jurisdiction over all resources in the water column and on and beneath the seabed. Article 76 of UNCLOS also establishes the criteria to determine areas beyond the 200 n.mi. (370 km) limit that could be defined as ?extended continental shelf,? where a nation could extend its sovereign rights over the seafloor and sub-seafloor (As used in UNCLOS, ?continental shelf? refers to a legally defined region of the sea floor rather than a morphological shallow-water area adjacent to continents commonly used by geologists and hydrographers.). This jurisdiction provided in Article 76 includes resources on and below the seafloor but not in the water column. The United States has been acquiring data to determine the outer limits of its extended continental shelf in the Arctic and has a vested interest in declaring and receiving international recognition of the reach of its extended continental shelf. The U.S. collaborated with Canada in 2008 and 2009 on extended continental shelf studies in the Arctic Ocean. The U.S. Coast Guard (USCG) Cutter Healy worked with the Canadian Coast Guard ship Louis S. St. Laurent to map the continental shelf beyond 200 n.mi. (370 km) in the Arctic. Each icebreaking vessel contributed different capabilities in order to collect data needed by both nations more efficiently in order to save money, avoid redundancy, and foster cooperation. Generally, the Healy collects bathymetric (sea-floor topography) data and the Louis S. St. Laurent collects seismic reflection profile data. The vessels work in concert when ice conditions are heavy, with one vessel breaking ice for the ship collecting data. The Canadian Environmental Assessments for these projects are available on line at http://www.ceaa.gc.ca/052

  15. Principal minors and rhombus tilings

    Kenyon, Richard; Pemantle, Robin

    2014-01-01

    The algebraic relations between the principal minors of a generic n × n matrix are somewhat mysterious, see e.g. Lin and Sturmfels (2009 J. Algebra 322 4121–31). We show, however, that by adding in certain almost principal minors, the ideal of relations is generated by translations of a single relation, the so-called hexahedron relation, which is a composition of six cluster mutations. We give in particular a Laurent-polynomial parameterization of the space of n × n matrices, whose parameters consist of certain principal and almost principal minors. The parameters naturally live on vertices and faces of the tiles in a rhombus tiling of a convex 2n-gon. A matrix is associated to an equivalence class of tilings, all related to each other by Yang–Baxter-like transformations. By specializing the initial data we can similarly parameterize the space of Hermitian symmetric matrices over R,C or H the quaternions. Moreover by further specialization we can parametrize the space of positive definite matrices over these rings. This article is part of a special issue of Journal of Physics A: Mathematical and Theoretical devoted to ‘Cluster algebras mathematical physics’. (paper)

    Full Text Available The 2015 presidential election in Côte d’Ivoire was seen as an important test for the country given the 2010 post-election crisis. Although the 2015 polls were peaceful, they were affected by problems not new to Côte d’Ivoire: lack of competition due to non-participation of major political actors, low voter turnout, mistrust in electoral institutions. The unpreparedness of the Commission Electorale Indépendante (CEI was also problematic, especially with respect to the revision of the voter list. Due to the boycott of partisans of former president Laurent Gbagbo and because of the support of the Rassemblement des Houphouëtistes pour la Démocratie et la Paix (RHDP, President Alassane Ouattara’s re-election was essentially a given from the start. With the ruling coalition firmly in control, Côte d’Ivoire appears stable. However, the country’s democratic deficit might lead to renewed violence once the RHDP has to pick Ouattara’s successor.

  18. Continuous thermodynamics for droplet vaporization: Comparison between Gamma-PDF model and QMoM

    Science.gov (United States)

    Laurent, Claire; Lavergne, Gérard; Villedieu, Philippe

    2009-06-01

    The Continuous Thermodynamics Model (CTM) (Cotterman et al., 1985) is a suitable method to reduce computational cost of multi-component vaporization models. The droplet composition is described by a probability density function (PDF) rather than tens of components in the classical Discrete Component Model (DCM). In the first CTM method developed for this application, the PDF was assumed to be a Γ-function (Hallett, 2000), but some problems had appeared in the case of vapor condensation at the droplet surface (Harstadt et al., 2003). The method put forward in this article, the Quadrature Method of Moments (QMoM), enables one to avoid any assumption on the PDF mathematical form. Following Lage who has developed this method for phase equilibria (Lage, 2007), this article widens the scope of QMoM to the modelling of multi-component droplet vaporization. The different CTM approaches are presented in the first part and the results obtained for a vapor condensation test case are then compared and analysed to illustrate improvements made by QMoM.

    Since the end of the 20th century, China has observed important growth in numerous sectors. China's Gross Domestic Product (GDP) has been multiply by 4 during the 2000-2010 decade (National Bureau of Statistics of China), mostly because of the industry's growth. These evolutions have been accompanied by important increases of atmospheric pollutants emissions (Yinmin et al, Atmo Env, 2016). As a consequence and for about 10 years now, Chinese authorities have been working to reduce pollutant levels, because atmospheric pollution is a major health issue for Chinese population especially within cities, for which World Health Organisation's standards for major pollutants (Ozone, PM2.5, PM10) are often exceeded. Particles have multiple issues, as they impact on health and global warming. Their impacts will depend on their sources (primary or secondary pollutants) and natures (Particle size distribution, chemical composition…). Controlling particles loading is a complex task as their sources are various and dispersed on the Chinese territories: mineral dust can be emitted from Chinese deserts in large amount (Laurent et al., GPC, 2006), ammonia can be emitted from agriculture and livestock (Kang et al., ACP, 2016) and lots of urban primary pollutants can be emitted from urbanized areas. It is then necessary to work from a continental to local scales to understand more precisely pollution of urbanized areas. It is then mandatory to discriminate and quantify pollution sources and to estimate the impact of natural pollution and the major contributing sources. We propose here an approach based on a model and satellite observation synergy to estimate what controls Chinese pollution. We use the regional chemistry transport model CHIMERE (Menut et al., GMD, 2013) to simulate atmospheric pollutants concentrations. A large domain (72°E-145°E; 17.5°N-55°N), with a ¼°x¼° resolution is used to make multi-annual simulations. CHIMERE model include most of the pollutants

    Aeolian aerodynamic roughness length in arid regions is a key parameter to predict the vulnerability of the surface to wind erosion, and, as a consequence, the related production of mineral aerosol (e.g. Laurent et al., 2008). Recently, satellite-derived roughness length at the global scale have emerged and provide the opportunity to use them in advanced emission schemes in global and regional models (i.e. Menut et al., 2013). A global map of the aeolian aerodynamic roughness length at high resolution (6 km) is derived, for arid and semi-arid regions merging PARASOL and ASCAT data to estimate aeolian roughness length. It shows very good consistency with the existing information on the properties of these surfaces. The dataset is available to the community, for use in atmospheric dust transport models. The present contribution analyses the behaviour of the NMMB/BSC-Dust model (Pérez et al., 2011) when the ASCAT/PARASOL satellite-derived global roughness length (Prigent et al, 2012) and the State Soil Geographic database Food and Agriculture Organization of the United Nations (STATSGO-FAO) soil texture data set (based on wet techniques) is used. We explore the sensitivity of the drag partition scheme (a critical component of the dust emission scheme) and the dust vertical fluxes (intensity and spatial patterns) to the roughness length. An annual evaluation of NMMB/BSC-Dust (for the year 2011) over Northern Africa and the Middle East using observed aerosol optical depths (AODs) from Aerosol Robotic Network sites and aerosol satellite products (MODIS and MISR) will be discussed.

    2012-01-01

    Relations between the operation of nuclear facilities and the health of populations are recurrent topics. For this reason, the national association of information committees and local commissions (ANCCLI), and the radiation protection and nuclear safety institute (IRSN) have jointly organized this seminar devoted to the monitoring of environment and public health. Its aim was to share the experience of the different actors in order to help the local commissions of information (CLI) in carrying out their own actions on these topics. The first day, the Golfech, Gravelines, Cadarache and Saint-Laurent-Des-Eaux CLIs presented their local environmental monitoring actions and their impact studies for facilities effluents. IRSN presented its methodology for the elaboration of its annual radiological status of the French environment. A round table permitted the different intervening parties to exchange about their monitoring goals. The second day, the Tricastin and Gravelines CLI, as well as the health care supervision institute InVS), presented different studies and attempts of answers to the health-impact questions coming from the surrounding communities. The contributions and limitations of public health studies were discussed through a presentation of the joint ANCCLI/IRSN/InVS methodological guidebook 'public health in the vicinity of nuclear facilities: how to approach the questions asked'. This document gathers the slides of the available presentations: 1 - Environmental monitoring by the Tarn-et-Garonne departmental laboratory in partnership with the Golfech's CLI (A. Calafat); 2 - Environmental monitoring by the Tarn-et-Garonne veterinary laboratory (V. Rossetto); 3 - Independent environmental monitoring by the Tarn-et-Garonne and occasional expertises around the Gravelines site (F. Cazier); 4 - Study of the impact on Durance river of the liquid radiological effluents of CEA-Cadarache site (C. Fourcaud); 5 - Study of the impact on Loire river of the chemical

    Richebois, E

    2000-07-01

    The objective of this work is to define improved 3-D core calculation methods based on the transport theory. These methods can be particularly useful and lead to more precise computations in areas of the core where anisotropy and steep flux gradients occur, especially near interface and boundary conditions and in regions of high heterogeneity (bundle with absorbent rods). In order to apply the transport theory a new method for calculating reflector constants has been developed, since traditional methods were only suited for 2-group diffusion core calculations and could not be extrapolated to transport calculations. In this thesis work, the new method for obtaining reflector constants is derived regardless of the number of energy groups and of the operator used. The core calculations results using the reflector constants thereof obtained have been validated on the EDF's power reactor Saint Laurent B1 with MOX loading. The advantages of a 3-D core transport calculation scheme have been highlighted as opposed to diffusion methods; there are a considerable number of significant effects and potential advantages to be gained in rod worth calculations for instance. These preliminary results obtained with on particular cycle will have to be confirmed by more systematic analysis. Accidents like MSLB (main steam line break) and LOCA (loss of coolant accident) should also be investigated and constitute challenging situations where anisotropy is high and/or flux gradients are steep. This method is now being validated for others EDF's PWRs' reactors, as well as for experimental reactors and other types of commercial reactors. (author)

The skin stiffens and becomes painful, while internally, organ function can be compromised by the less elastic collagen. Diagnosis of SSc is often only possible in advanced cases by which treatment time is limited. A more detailed analysis of SSc may provide better future treatment options and information of disease progression. Recently, the histological stain picrosirius red showing collagen register has been combined with atomic force microscopy (AFM to study SSc. Skin from healthy individuals and SSc patients was biopsied, stained and studied using AFM. By investigating the crosslinking of collagen at a smaller hierarchical stage, the effects of SSc were more pronounced. Changes in morphology and Young’s elastic modulus were observed and quantified; giving rise to a novel technique, we have termed “quantitative nanohistology”. An increase in nanoscale stiffness in the collagen for SSc compared with healthy individuals was seen by a significant increase in the Young’s modulus profile for the collagen. These markers of stiffer collagen in SSc are similar to the symptoms experienced by patients, giving additional hope that in the future, nanohistology using AFM can be readily applied as a clinical tool, providing detailed information of the state of collagen.

    The objective of this work proposed in the framework of the S.E.N.S.I.B. project on the permanent meadows areas is to compare the sensitivity of these surfaces and cheese maker sector which are associated with them, and to identify the processes which determine this sensitivity. The realization of this objective will lean on certain data of activities acquired recently by the I.R.S.N. (compartments: soils, herb, milk and cheese), as well as on new measures, on three sites: Saint-Laurent-de-Geris ( West), Beaune-Le-Froid ( center), and Massif of Jura (East). Two scales of transfers observation and sensitivity are retained. In a first time, the sensitivity of meadows areas will studied at the regional scale, from data acquired in the Massif du Jura ( between 300 and 1200 metres up). In a second time, a study will allow to compare the sensitivity of three areas retained (West, Center, East) at the national scale. The expertise will be focused on the factors of sensitivity of the transfer soil-herb and the factors of sensitivity bound to the cheese makers sectors. The data of the already available zones of study create strong variabilities of the rates of {sup 137}Cs transfer in the interfaces soil / herb and herb / milk, letting suppose that the nature of soils, the quantity and the quality of food ingested by the cattle constitutes dominating factors of sensitivity. Besides, the size of the basin of milk collection, extremely variable from a site of study in the other one, has to influence the contamination of cheeses and as such, it establishes an important factor of sensitivity of the cheese makers sector.

    Despite the last decades of diminishing sea-ice cover in the Arctic Ocean, ship operations are only possible in vast sectors of the central Arctic using the most capable polar-class icebreakers. There are less than a handful of these icebreakers outfitted with modern seafloor mapping equipment. This implies either fierce competition between those having an interest in using these icebreakers for investigations of the shape and properties of Arctic Ocean seafloor or, preferably, collaboration. In this presentation examples will be shown of scientific discoveries based on mapping data collected during Arctic Ocean icebreaker expeditions carried out for the purpose of substantiating claims for an extended continental shelf under United Nations Convention of the Law of the Sea (UNCLOS) Article 76. Scientific results will be presented from the suite of Lomonosov Ridge off Greenland (LOMROG) expeditions (2007, 2009, and 2012), shedding new light on Arctic Ocean oceanography and glacial history. The Swedish icebreaker Oden was used in collaboration between Sweden and Denmark during LOMROG to map and sample portions of the central Arctic Ocean; specifically focused on the Lomonosov Ridge north of Greenland. While the main objective of the Danish participation was seafloor and sub-seabed mapping to substantiate their Article 76 claim, LOMROG also included several scientific components, with scientists from both countries involved. Other examples to be presented are based on data collected using US Coast Guard Cutter Healy, which for several years has carried out mapping in the western Arctic Ocean for the US continental shelf program. All bathymetric data collected with Oden and Healy have been contributed to the International Bathymetric Chart of the Arctic Ocean (IBCAO). This is also the case for bathymetric data collected by Canadian Coast Guard Ship Louis S. St-Laurent for Canada's extended continental shelf claim. Together, the bathymetric data collected during these

Belimumab is the first of a new class of drug targeting B cell-stimulating factors or their receptors to reach the market. Its target, BLyS, also known as BAFF (B cell-activating factor from the tumor necrosis factor family, is a type II transmembrane protein that exists in both membrane-bound and soluble forms. Additionally to a robust rational from murine experiments conducted in lupus prone mice, BLyS circulating levels are increased in SLE patients. After the negative results of a Phase II trial, two Phase III trials met their primary endpoints. Some SLE patients are still refractory to the standard options of care or necessitate prolonged high-dose corticotherapy and/or long-term immunosuppressive regimens. However, some experts still feel that the effect of this biologic might not be clinically relevant and blame the use of the new systemic lupus response index as well as the discrepancies between both trials and the noninclusion of the severe form of the disease as nephritis. In this review, we aim to discuss the characteristics of belimumab, critically evaluate the different steps of its development, and consider its future place in the arsenal against SLE, taking into account the patients’ perspectives.Keywords: systemic lupus erythematosus, belimumab, treatment, monoclonal antibodies, adverse effects, BLyS

    The USCG cutter Healy is the U.S. Arctic research icebreaker. Prior to the 2008 season, a number of upgrades and improvements were made to the science systems. These included the addition of two Bell BGM-3 marine gravity meters. The vessel's existing meterological sensors were enhanced with two RM Young model 85004 heated ultrasonic anemometers; a Paroscientific, Inc. model "MET-3A" air temperature, humidity and barometric pressure subsystem; and an RM Young model 50202 heated rain gauge. The flow through sea water system was updated with new flow meters, a SeaBird SBE45 thermosalinograph, long and a short wave radiation sensors, a Seapoint fluorometer. A Milltech Marine Smart Radio model SR161 Automatic Identification System (AIS) receiver and an updated interface to real-time winch and wire performance have been added. Our onboard real-time GIS has been updated to include real-time plotting of other ship tracks from our AIS receiver and the ability for users to save and share planned tracks. For the HLY0806 leg, we implemented a SWAP ship-to ship wireless connection for our two-ship operations with the Canadian icebreaker Louis S. St. Laurent similar to the one we implemented for our two-ship program with the Swedish icebreaker Oden in 2005. We updated our routine delivery of underway data to investigators, as well as a copy for archiving to the NSF-supported Marine Geoscience Data System (MGDS), using portable "boomerang" drives. An end-user workstation was added to accommodate increasing demand for onboard processing. Technical support for science on the Healy is supported by the U.S. National Science Foundation.

    Full Text Available The traditional Romanian costume such as the entire popular art (architecture, woodcarvins, pottery etc. was born and lasted in our country since ancient times. Closely related to human existence, the traditional costume reflected over the years as reflected nowadays, the mentality and artistic conception of the people. Today the traditional Romanian costume became an inspiration source to the wholesale fashion production industry designers, both Romanian and international. Although the contemporary designers are working in accordance with a vision, using a wide area of styles, methods and current technology, they usually return to traditional techniques and ethnic folklore motifs, which converts and resize them, integrating them in their contemporary space. Adrian Oianu is a very appreciated Romanian designer who launched two collections inspired by his native’s country traditional costumes: “Suflecata pan’ la brau” (“Turned up ‘til the belt” and “Bucurie” (“Joy”. Dorin Negrau had as inspiration for his “Lost” collection the traditional costume from the Bihor region. Yves Saint Laurent had a collection inspired by the Romanian traditional flax blouses called “La blouse roumaine”. The paper presents the traditional Romanian values throw fashion collections. The research activity will create innovative concepts to support the garment industry in order to develop their own brand and to bring the design activities in Romania at an international level. The research was conducted during the initial stage of a project, financed through national founds, consisting in a documentary study on ethnographic characteristics of the popular costume from different regions of the country.

    The main items of equipment involved in the running of BUGEY 1, the test procedure adopted and the results obtained are reported. The primary heat-extraction circuit is placed inside a prestressed concrete vessel and consists of: the reactor itself, the supporting structures, the exchanger and 4 turbo-blowers. The stach is made up of prismatic graphite rods forming a regular hexagonal lattice. The annular fuel element, cooled inside and outside consists of a clad natural uranium tube. The secondary circuit corresponds to the conventional part of a thermal centre. Four auxiliary boilers supply steam to the turbo-blowers, turbopumps and degassers providing residual heat evacuation at all-times. The principle of the control system is that of Saint-Laurent-des-Eaux. Trials were carried out on the site itself: blank tests, live tests, general tests. The general testing phase was divided into three periods: aptitude, starting up, trial run. The aptitude period precedes reactor loading and was foreseen to test the state of the circuits and the reliability of each function. The ultimate phase involved the pneumatic trial of the pressure vessel. After loading, two divergences were carried out in December 1971 and the automatic divergence process was adjusted. The start-up period lasted from January 1972 until the end of the same year. The power use tests took place (March 6th-October 23rd 1972) in 7 steps increasing from 100 to 1750Mw(th). A revision period was organized during the summer of 1972. The trial run extended through December 1972 and into 1973. During two years industrial operation the number of ill-timed control rod drops decreased gradually until September 1973 after which the plant ran continuously until June 1974, date of the annual shut-down.

    Electron-positron pair production by collision of photons is investigated in view of application to pulsar physics. We compute the absorption rate of individual gamma-ray photons by an arbitrary anisotropic distribution of softer photons, and the energy and angular spectrum of the outgoing leptons. We work analytically within the approximation that 1 ≫ mc2/E > ɛ/E, with E and ɛ the gamma-ray and soft-photon maximum energy and mc2 the electron mass energy. We give results at leading order in these small parameters. For practical purposes, we provide expressions in the form of Laurent series which give correct reaction rates in the isotropic case within an average error of ˜ 7 per cent. We apply this formalism to gamma-rays flying downward or upward from a hot neutron star thermally radiating at a uniform temperature of 106 K. Other temperatures can be easily deduced using the relevant scaling laws. We find differences in absorption between these two extreme directions of almost two orders of magnitude, much larger than our error estimate. The magnetosphere appears completely opaque to downward gamma-rays while there are up to ˜ 10 per cent chances of absorbing an upward gamma-ray. We provide energy and angular spectra for both upward and downward gamma-rays. Energy spectra show a typical double peak, with larger separation at larger gamma-ray energies. Angular spectra are very narrow, with an opening angle ranging from 10-3 to 10-7 radians with increasing gamma-ray energies.

  16. Investigating the Keratinolytic Activities of the Bacteria Isolated from Different Sources

    2017-12-01

    Background InformationThe development of microbial keratinase has gained increasing attention over the million tons of keratinous wastes generated by the worldwide livestock population. Keratinous wastes not only serve as the niche for pathogenic microorganisms, but also they collapse environmental balance for being the source of air, soil, and water pollutions. Conversely, microbial keratinases can convert the unexploited keratinous wastes into bioaccessible animal feed. However, because of the recalcitrant structure of keratin, the complete keratin degradation is difficult to achieve with one keratinase as opposed to recombinant keratinases. Therefore, this study is designed to isolate the bacteria from different sources and to evaluate their keratinolytic activities using azokeratin substrates. Materials and Methods Soil, horse hooves, penguin stool, and chicken stool are collected from different sites. These samples are serially diluted and then streaked on feather-meal agar plates. Single colonies are screened for the ability to hydrolyze keratin. The isolate of single colonies is cultivated in a whole-feather medium. The sample is then centrifuged, and the supernatant is used for crude enzyme preparation. Azokeratin is synthesized by coupling bristle keratin with diazotized laurent's acid, and it is used as a substrate for assaying keratinase activity by using a spectrophotometer. ConclusionThis study will compare the keratinase activities on bristle azokeratin substrates from three different samples and thus evaluate the bacterium with the best ability to hydrolyze keratin amongst the three. Further steps will be taken to produce a blend of enzymes generated and select the optimum combination that can most efficiently degrade keratin.

    Full text: Distributions of particle-reactive radionuclides 239,240 Pu, 238 Pu, 210 Pb and 210 Po measured in the central Arctic Ocean during expeditions on the Canadian icebreakers, CCGS Henry Larsen in 1993 and CCGS Louis St Laurent in 1994 and 1995 reflect their sources, circulation pathways and scavenging histories. Disequilibria between the naturally occurring 210 Pb (T 1/2 = 22.3 y) and its grandparent 226 Ra (T 1/2 = 1600 y) can be used to determine residence times for dissolved 210 Pb on the order of 10 to 100 years. Disequilibria is evident throughout the water column in the Arctic Ocean but is greatest in the halo-cline water (100 to 300 m) in the Makarov, Canada and Amundsen Basins where minima in 210 Pb activities are observed. Vertical distributions of 239,240 Pu, a long-lived radionuclide derived mainly from atmospheric nuclear fallout, are remarkably similar throughout the Arctic Ocean. Profiles are characterized by low activities in the surface mixed layer, increased levels through the halo-cline and maximum values in the Atlantic layer, decreasing to levels below the detection limit at depths greater than 1500 m. Comparison of the ratio of 239,240 Pu to 90 Sr, a non particle-reactive fallout radionuclide, to the global fallout ratio is used to determine 239,240 Pu removal rates. Both particle-reactive radionuclide distributions are consistent with recent contact of surface and halo-cline water with particle-rich continental shelf regions where 239,240 Pu and 210 Pb evidently undergo enhanced scavenging from seawater. Atlantic layer water is characterized by fallout 239,240 Pu/ 90 Sr ratios and limited 210 Pb/ 226 Ra disequilibria, which provides evidence for reduced scavenging and interaction of Atlantic layer water with shelf regions

    Full Text Available Resumo O voluntariado é um fenômeno social crescente no contexto atual e que se apresenta como alternativa à lógica do capitalismo na gestão das organizações da sociedade civil. Contudo é possível que haja contradições no agir do voluntário, cuja ação humana pode estar sendo mediada por fatores comportamentais subjacentes ao comportamento aparente, nem sempre considerado nobre, como, por exemplo, o egoísmo. O presente ensaio teórico tem como objetivo compreender o que está por trás da ação humana no comportamento do voluntário das organizações da sociedade civil (OSCs, razão pela qual os argumentos teóricos foram construídos pela Sociologia Pragmática, que busca encontrar razões do agir pelas mediações simbólicas, em detrimento da psicologia comportamental. Afirma-se que os voluntários são dotados de comportamento racional e justificável por três regimes pragmáticos desenvolvidos por Laurent Thévenot e pelos conceitos complementares de Frédéric Vandenberghe; ambos defendem que as ações humanas são justificáveis. Os argumentos apresentados confirmam teoricamente que os fatores comportamentais dos voluntários produzem efeitos nos resultados das OSCs, como o seu baixo grau de envolvimento, uma vez que as justificativas do agir podem estar centralizadas nos mundos “da fama” e o “mercantil”, contribuindo para gerar inquietações entre os pesquisadores sobre a possível inferência daquilo que está por trás da ação humana.

  19. Study of a nuclear graphite waste 14C decontamination process by CO2 gasification

    2014-01-01

    The decommissioning of French gas cooled nuclear reactors (UNGG), all arrested since 1994, will generate 23,000 tons of graphite waste classified Low Level and Long Lived and notably containing 14 C. The aim of this thesis is to study a new method for selective extraction of this radionuclide by CO 2 gasification.The multi-scale organization of virgin and irradiated graphite has been studied by a coupling between microspectrometry Raman and transmission electron microscopy. With the neutron fluence, the structure degrades and the nano-structure can be greatly changed. In extreme cases, the lamellar nano-structure nuclear graphite has become nano-porous. Furthermore, these damages are systematically heterogeneous. An orientation effect of 'crystallites', shown experimentally by ion implantation, could be a cause of these heterogeneities.This study also showed that from a specific fluence, there is an important development of nano-porous zones coinciding with a dramatic 14 C concentration increase. This radionuclide could be preferentially concentrated in the nano-porous areas which are potentially more reactive than the remaining laminar areas which could be less rich in 14 C. This process by CO 2 gasification was firstly tested on 'analogous' non-radioactive materials (mechanically milled graphite). These tests confirmed, for temperatures between 950 and 1000 C, the selective and complete elimination of nano-porous areas.Tests were then carried out on graphite waste from Saint-Laurent-des-Eaux A2 and G2 reactors. The results are promising with notably the quarter of 14 C inventory extracted for a weight loss of only few percent. Up to 68 % of 14 C inventory was extracted, but with an important gasification. Thus, this treatment could allow extracting selectively a share of 14 C inventory (mobile or linked to nano-porous areas) and allows imagining alternative scenarios for graphite waste managing.

  20. Intrinsic motivation and attentional capture from gamelike features in a visual search task.

    In psychology research studies, the goals of the experimenter and the goals of the participants often do not align. Researchers are interested in having participants who take the experimental task seriously, whereas participants are interested in earning their incentive (e.g., money or course credit) as quickly as possible. Creating experimental methods that are pleasant for participants and that reward them for effortful and accurate data generation, while not compromising the scientific integrity of the experiment, would benefit both experimenters and participants alike. Here, we explored a gamelike system of points and sound effects that rewarded participants for fast and accurate responses. We measured participant engagement at both cognitive and perceptual levels and found that the point system (which invoked subtle, anonymous social competition between participants) led to positive intrinsic motivation, while the sound effects (which were pleasant and arousing) led to attentional capture for rewarded colors. In a visual search task, points were awarded after each trial for fast and accurate responses, accompanied by short, pleasant sound effects. We adapted a paradigm from Anderson, Laurent, and Yantis (Proceedings of the National Academy of Sciences 108(25):10367-10371, 2011b), in which participants completed a training phase during which red and green targets were probabilistically associated with reward (a point bonus multiplier). During a test phase, no points or sounds were delivered, color was irrelevant to the task, and previously rewarded targets were sometimes presented as distractors. Significantly longer response times on trials in which previously rewarded colors were present demonstrated attentional capture, and positive responses to a five-question intrinsic-motivation scale demonstrated participant engagement.

    Full Text Available Wine is a beverage that made from grape berries. However, without beneficial bacteria, we would not produce good wine. But very often wines contain acetic acid bacteria, which are undesirable in winemaking process. Acetic acid bacteria as known as a vinegar bacteria are Gram-negative, aerobic, rod-shaped and ubiquitous bacteria. This study was focused on species of acetic acid bacteria, specifically Acetobacter aceti that make spoilage in wine.The aim of our study was the identification of Acetobacter aceti in spoiled red wine samples, with plate dilution method on agar plates and using sensitive Real-time PCR (qPCR method. We cultivated Acetobacter aceti on GYC agar at 30°C, 48h. The one of main objective in the present work was the test fast, sensitive and reliable technique such as quantitative Real-time PCR and detecting the presence of Acetobacter aceti in wine samples with positive Acetobacteraceti control on amplification plot and melting curve. The next objective before  qPCR analysis was DNA extraction from wine samples incubated for one week at 28°C aerobically. We used five different red wine samples for this experiment: Alibernet 2013, Blaufränkisch 2013, Cabernet Sauvignon 2013, Dunaj 2012 and Saint-Laurent 2012. Next we extracted DNA from wine samples and from pure Acetobacter aceti CCM 3620T strain purchased from Czech collection of microorganisms in Brno. Susceptibility ofAcetobacter aceti was varied in different isolates from 102 to 107 CFU.mL-1. The number of Acetobacter cells on GYC medium ranged from 4.05 to 4.83log CFU.mL-1 in differentwine samples.The higher number of Acetobacter cells (4.83 log CFU.mL-1 was found in Cabernet Sauvignon 2013 wine.

    The HD97950 cluster and its immediate surroundings in the giant HII region NGC3603 were observed with the Hubble Space Telescope (HST). The ultraviolet (UV) data were taken with the High Resolution Channel (HRC) of the Advanced Camera for Surveys (ACS) in 2005 (GO 10602, PI: Jesus Maiz Apellaniz) through the F220W, F250W, F330W, and F435W filters. The HRC is characterized by a spatial resolution of 0.03"/pixel and a field of view of 29''*25''. The optical observations were carried out with the Wide Field and Planetary Camera 2 (WFPC2) in two epochs: 1997 (GO 6763, PI: Laurent Drissen) and 2007 (GO 11193, PI: Wolfgang Brandner) through the F555W, F675W, and F814W filters. The Planetary Camera (PC) chip was centered on the cluster (0.045"/pixel, 40''*40'') for both programs. Pang et al. 2013 (cat. J/ApJ/764/73) reduced the two-epoch WFPC2 data and identified more than 400 member stars on the PC chip via relative proper motions. Of these member stars, 142 are in common between the HRC and PC images and thus have UV and optical photometry available (see Table1). Among the HD97950 cluster member stars determined from relative proper motions (Pang et al. 2013, cat. J/ApJ/764/73, Table2), there are five main-sequence (MS) stars located in the cluster with projected distances of r<0.7pc from the center, for which there are also spectral types available from Table3 of Melena et al. (2008AJ....135..878M). The photometry of these five MS stars is presented in Table2. The individual color excesses and extinctions of the member main sequence stars are listed in Table3.

    The prevalence of smoking in HIV-infected subjects is high. As a smoking cessation aid, varenicline (Champix(®), Pfizer, Saint-Laurent, QC, Canada or Chantix(®), Pfizer, Mission, KS) has not been previously evaluated in HIV-infected smokers. In this multicenter pilot open label study, varenicline 1.0 mg was used twice daily for 12 weeks with dose titration in the first week. Adverse events (AEs) during the treatment period were recorded. Changes from baseline in laboratory tests, vital signs, daily cigarette consumption, nicotine dependence, and withdrawal were measured through week 24. Self-reported abstinence was validated by serum cotinine at week 12. We enrolled 36 subjects with a mean of 29 pack-years of smoking and a minimum of 4 cigarettes per day. All but 1 were male, 33 (92%) were white. The most frequently reported AEs were nausea (33%), abnormal dreams (31%), affect lability (19%), and insomnia (19%). Six (17%) subjects discontinued varenicline due to AEs. No grade 3/4 laboratory abnormalities or serious AEs occurred during the study. There was no significant change in HIV viral load. CD4 counts increased by 69 cells/mm3 (p = 0.001) at week 24. Serum cotinine-verified 4-week continuous abstinence rate through weeks 9-12 was 42% (95% confidence interval [CI]: 26-58%). AEs and abstinence rates were comparable to those in published randomized controlled trials conducted in generally healthy HIV-negative smokers. Varenicline was safe and appears effective among HIV-infected smokers in this exploratory study, although AEs were common. The most common AE was nausea, with no adverse effect on HIV treatment outcome. Close monitoring of liver enzymes and blood pressure is recommended for HIV-positive smokers taking varenicline.

  5. Stable isotope reactive transport modeling in water-rock interactions during CO2 injection

    Stable isotopes can be of great usefulness in the characterization and monitoring of CO2 sequestration sites. Stable isotopes can be used to track the migration of the CO2 plume and identify leakage sources. Moreover, they provide unique information about the chemical reactions that take place on the CO2-water-rock system. However, there is a lack of appropriate tools that help modelers to incorporate stable isotope information into the flow and transport models used in CO2 sequestration problems. In this work, we present a numerical tool for modeling the transport of stable isotopes in groundwater reactive systems. The code is an extension of the groundwater single-phase flow and reactive transport code HYTEC [2]. HYTEC's transport module was modified to include element isotopes as separate species. This way, it is able to track isotope composition of the system by computing the mixing between the background water and the injected solution accounting for the dependency of diffusion on the isotope mass. The chemical module and database have been expanded to included isotopic exchange with minerals and the isotope fractionation associated with chemical reactions and mineral dissolution or precipitation.

    Full Text Available Luc Boltanski, com Laurent Thévenot, propõe que a avaliação das con- tribuições sociais ocorre num contexto em que é necessário que cada um faça reconhecer o seu respectivo lugar nas economias de grandeza mediante justificação, onde uma diversidade de critérios valorativos será ponderada. Essa disputa em torno da justificação tem razoável proximidade com a luta pelo reconhecimento do desempenho (Leistung, que Axel Honneth coloca como terceira esfera em sua teoria do reconhecimento, na qual para além da igualdade da esfera do direito as diferenças se fariam justificadamente presentes. É passível de discussão como os horizontes de valores e de fins que permitem a avaliação da contribuição são partilhados: em Boltanski claramente divergentes e em Honneth aparentemente compartilhados, enquanto Michael Walzer supõe que os valores são compartilhados, mas enfatiza a necessidade de cuidadosa distinção das esferas de justiça a que em cada caso os valores são referidos. Essa distinção de esferas, aparentemente, pode permitir uma ponte com as cidades na proposição de Boltanski e com as esferas do reconhecimento da teoria de Axel Honneth. No texto nós nos propomos a explorar possíveis semelhanças e diferenças concepcionais dessas três proposições

    Accurate sex assignment of ancient human remains usually relies on the availability of coxal bones or well-preserved DNA. Iron (Fe) and copper (Cu) stable isotope compositions ((56)Fe/(54)Fe and (65)Cu/(63)Cu, respectively) were recently measured in modern human blood, and an unexpected result was the discovery of a (56)Fe-depletion and a (65)Cu-enrichment in men's blood compared to women's blood. Bones, being pervasively irrigated by blood, are expected to retain the (56)Fe/(54)Fe and (65)Cu/(63)Cu signature of blood, which in turn is useful for determining the sex of ancient bones. Here, we report the (56)Fe/(54)Fe, (65)Cu/(63)Cu, and (66)Zn/(64)Zn ratios from a suite of well-preserved phalanxes (n = 43) belonging to individuals buried in the 17th and 18th centuries at the necropolis of Saint-Laurent de Grenoble, France, and for which the sex was independently estimated from pelvic bone morphology. The metals were purified from the bone matrix by liquid chromatography on ion exchange resin and the isotope compositions were measured by multiple-collector inductively coupled plasma mass spectrometry. The results show that, as expected from literature data on blood, male bone iron is depleted in (56)Fe and enriched in (65)Cu relative to female. No sex difference is found in the (66)Zn/(64)Zn ratios of bone. The concentration and isotopic data show no evidence of soil contamination. Four samples of five (77%) can be assigned their correct sex, a result comparable to sex assignment using Fe and Cu isotopes in blood (81%). Isotopic analysis of metals may therefore represent a valid method of sex assignment applicable to incomplete human remains. Copyright © 2012 Wiley Periodicals, Inc.

  9. Comparison of automated repetitive-sequence-based polymerase chain reaction and spa typing versus pulsed-field gel electrophoresis for molecular typing of methicillin-resistant Staphylococcus aureus.

    Automated repetitive polymerase chain reaction (PCR) (DiversiLab, bioMérieux, St. Laurent, Quebec, Canada) and single locus sequence typing of the Staphylococcus protein A (spa) gene with spa-type assignment by StaphType RIDOM software were compared to pulsed-field gel electrophoresis (PFGE) as the "gold standard" method for methicillin-resistant Staphylococcus aureus (MRSA) typing. Fifty-four MRSA isolates were typed by all methods: 10 of known PFGE CMRSA type and 44 clinical isolates. Correct assignment of CMRSA type or cluster occurred for 47 of 54 (87%) of the isolates when using a rep-PCR similarity index (SI) of ≥95%. Rep-PCR gave 7 discordant results [CMRSA1 (3), CMRSA2 (1), CMRSA4 (1), and CMRSA10 (2)], and some CMRSA clusters were not distinguished (CMRSA10/5/9, CMRSA 7/8, and CMRSA3/6). Several spa types occurred within a single PFGE or repetitive PCR types among the 19 different spa types found. spa type t037 was shared by CMRSA3 and CMRSA6 strains, and CMRSA9 and most CMRSA10 strains shared spa type t008. Time to results for PFGE, repetitive PCR, and spa typing was 3-4 days, 24 h, and 48 h, respectively. The annual costs of using spa or repetitive PCR were 2.4× and 1.9× higher, respectively, than PFGE but routine use of spa typing would lower annual labor costs by 0.10 full-time equivalents compared to PFGE. Repetitive PCR is a good method for rapid outbreak screening, but MRSA isolates that share the same repetitive PCR or PFGE patterns can be distinguished by spa typing. Copyright © 2011 Elsevier Inc.

Understanding the process of mineral deposition is important for the development of treatments for mineralization-related diseases and also for the innovation and development of scaffolds. This review provides a thorough overview of the up-to-date information on the theories describing the possible mechanisms and the factors implicated as agonists and antagonists of mineralization. Then, the role of calcium and phosphate ions in the maintenance of teeth and bone health is described. Throughout the life, teeth and bone are at risk of demineralization, with particular emphasis on teeth, due to their anatomical arrangement and location. Teeth are exposed to food, drink, and the microbiota of the mouth; therefore, they have developed a high resistance to localized demineralization that is unmatched by bone. The mechanisms by which demineralization–remineralization process occurs in both teeth and bone and the new therapies/technologies that reverse demineralization or boost remineralization are also scrupulously discussed. Technologies discussed include composites with nano- and micron-sized inorganic minerals that can mimic mechanical properties

  11. The safety approach in the operation of EDF power plants

    Bertron, L.; Mira, J.J.

    1988-01-01

    To get a view on what is involved in maintaining a high level of safety in the operation of EdF nuclear power plants, it may be recalled that in 1987, 76 % of the EdF production was nuclear. The nuclear plants include thirty-four standard PWR 900 plants, fourteen PWR 1300 plants, the 305 MW SENA PWR, the four 500 MW GCR: CHINON A3 plant, St-LAURENT A1 (390 MW), A2 (450 MW) and BUGEY 1 (540 MW), the 233 MW PHENIX fast breeder reactor and the CREYS-MALVILLE 1200 MW fast breeder reactor, now being prepared for a new startup after the 1987 incident. So the importance of a safe operation of this investment is considerable for EdF, which is the designer, owner, industrial architect and operator. According to the French regulations, EdF is responsible for the safe operation of its power plants. A considerable human component is also at stake, as the safe operation of plants implies all the personnel to varying degrees. There are 15,000 such employees, all of whom have to be trained, competent and motivated. The operation of this system for 340 reactor-years has to-date resulted in no incident of any significant impact on the environment. Right from the start, safety in operation has always been an essential and clearly stated priority. Among other lessons the Three-Mile Island and Chernobyl accidents have reinforced the conviction that the human factors, the man-machine interface, and the safety culture were determining elements. With forty-eigh PWR plants in service, the problem is to maintain safe operation of a system now running at cruising speed, but also including some units (particularly the GCRs) that must be prepared for decommissioning. In addition EDF has to demonstrate the safe operations of CREYS MALVILLE, fast breeder reactor

  13. A toolbox to solve coupled systems of differential and difference equations

    International Nuclear Information System (INIS)

    2016-01-01

    We present algorithms to solve coupled systems of linear differential equations, arising in the calculation of massive Feynman diagrams with local operator insertions at 3-loop order, which do not request special choices of bases. Here we assume that the desired solution has a power series representation and we seek for the coefficients in closed form. In particular, if the coefficients depend on a small parameter ε (the dimensional parameter), we assume that the coefficients themselves can be expanded in formal Laurent series w.r.t. ε and we try to compute the first terms in closed form. More precisely, we have a decision algorithm which solves the following problem: if the terms can be represented by an indefinite nested hypergeometric sum expression (covering as special cases the harmonic sums, cyclotomic sums, generalized harmonic sums or nested binomial sums), then we can calculate them. If the algorithm fails, we obtain a proof that the terms cannot be represented by the class of indefinite nested hypergeometric sum expressions. Internally, this problem is reduced by holonomic closure properties to solving a coupled system of linear difference equations. The underlying method in this setting relies on decoupling algorithms, difference ring algorithms and recurrence solving. We demonstrate by a concrete example how this algorithm can be applied with the new Mathematica package SolveCoupledSystem which is based on the packages Sigma, HarmonicSums and OreSys. In all applications the representation in x-space is obtained as an iterated integral representation over general alphabets, generalizing Poincare iterated integrals.

    Full Text Available Christopher Kent, Julia Metzner, Laurent BollagDepartment of Anesthesiology and Pain Medicine, University of Washington Medical Center, Seattle, WA, USAAbstract: Care for patients undergoing ambulatory procedures is a broad and expanding area of anesthetic and surgical practice. There were over 35 million ambulatory surgical procedures performed in the US in 2006. Ambulatory procedures are diverse in both type and setting, as they span the range from biopsies performed under local anesthesia to intra-abdominal laparoscopic procedures, and are performed in offices, freestanding ambulatory surgery centers, and ambulatory units of hospitals. The information on adverse events from these varied settings comes largely from retrospective reviews of sources, such as quality-assurance databases and closed malpractice claims. Very few if any ambulatory procedures are emergent, and in comparison to the inpatient population, ambulatory surgical patients are generally healthier. They are still however subject to most of the same types of adverse events as patients undergoing inpatient surgery, albeit at a lower frequency. The only adverse events that could be considered to be unique to ambulatory surgery are those that arise out of the circumstance of discharging a postoperative patient to an environment lacking skilled nursing care. There is limited information on these types of discharge-related adverse events, but the data that are available are reviewed in an attempt to assist the practitioner in patient selection and discharge decision making. Among ambulatory surgical patients, particularly those undergoing screening or cosmetic procedures, expectations from all parties involved are high, and a definition of adverse events can be expanded to include any occurrence that interrupts the rapid throughput of patients or interferes with early discharge and optimal patient satisfaction. This review covers all types of adverse events, but focuses on the more

    Full Text Available Après avoir insisté sur les apports d'une approche naturaliste pour les sciences sociales, cet article vise tout d'abord à montrer que les éventuels risques de réductionnisme dont sont soupçonnés les sociologues cognitifs ne s'appliquent en rien à l'article de Laurence Kaufmann et Laurent Cordonier. Par contre, s'il est aujourd'hui nécessaire d'envisager une forme de « compatibilisme » entre les sciences de l'esprit et les sciences sociales, il faut convenir que certaines caractéristiques de ces dernières ne se prêtent pas facilement à une méthodologie strictement expérimentale. D'une part, les sciences sociales ont un rôle de « lecture » des réalités socio-politiques qui ne donne pas vraiment prise aux méthodes des sciences dites « dures ». D'autre part, les « réductions » opérées en laboratoire doivent être complétées par des observations de terrain. Enfin, les descriptions des formes de vie humaines ne peuvent être strictement objectivantes : comme l'a bien montré Jeanne Favret-Saada, ce n'est qu'en acceptant d'être affecté à la « première personne » que l'anthropologue a une chance de comprendre « ce que ça fait » d'être Bororo ou victime d'une attaque de sorcellerie.Towards a compatibilism between cognitive and social sciencesThe first objective of this paper is to shed light on the advantages of a naturalistic approach for social sciences and to show that Laurence Kaufmann and Laurent Cordonier cannot be accused of reductionism. However, if a form of compatibilism between social and cognitive sciences is necessary, there are certain characteristics of social sciences that cannot be tackled by a strict experimental approach. On the one hand, the role of the social sciences is to give meaning to complex historical realities that cannot be enclosed in a laboratory. One the other hand, experimental results have to be completed with field observations. And last but not least

Although both multiple sclerosis (MS and fibromyalgia (FM possibly include chronic pain, they seem to elicit different disease representations because of the difference in their respective etiology, the former presenting evidence of underlying lesions as opposed to the latter. Thus, we investigated whether patients with FM differed from patients with MS with respect to their perception of “own” pain as well as others' pain. In addition, the psychological concomitant factors associated with chronic pain were considered. Chronic pain patients with FM (n=13 or with MS (n=13 participated in this study. To assess specific pain-related features, they were contrasted with 12 other patients with MS but without chronic pain and 31 controls. A questionnaire describing imaginary painful situations showed that FM patients rated situations applied to themselves as less painful than did the controls. Additionally, pain intensity attributed to facial expressions was estimated as more intense in FM compared with the other groups of participants. There is good

However, few studies have looked at the potential synergetic effects of combining physical and cognitive training in a single study. Prior trials on combined training have led to interesting yet equivocal results. The aim of this study was to examine the effects of combined physical and cognitive interventions on physical fitness and neuropsychological performance in healthy older adults.Methods: Seventy-six participants were randomly assigned to one of four training combinations using a 2×2 factorial design. The physical intervention was a mixed aerobic and resistance training program, and the cognitive intervention was a dual-task (DT training program. Stretching and toning exercises and computer lessons were used as active control conditions. Physical and cognitive measures were collected pre- and postintervention.Results: All groups showed equivalent improvements in measures of functional mobility. The aerobic–strength condition led to larger effect size in lower body strength, independently of cognitive training

    Full Text Available The maximally-decoupled method has been considered as a theory to apply an basic idea of an integrability condition to certain multiple parametrized symmetries. The method is regarded as a mathematical tool to describe a symmetry of a collective submanifold in which a canonicity condition makes the collective variables to be an orthogonal coordinate-system. For this aim we adopt a concept of curvature unfamiliar in the conventional time-dependent (TD self-consistent field (SCF theory. Our basic idea lies in the introduction of a sort of Lagrange manner familiar to fluid dynamics to describe a collective coordinate-system. This manner enables us to take a one-form which is linearly composed of a TD SCF Hamiltonian and infinitesimal generators induced by collective variable differentials of a canonical transformation on a group. The integrability condition of the system read the curvature C = 0. Our method is constructed manifesting itself the structure of the group under consideration. To go beyond the maximaly-decoupled method, we have aimed to construct an SCF theory, i.e., υ (external parameter-dependent Hartree-Fock (HF theory. Toward such an ultimate goal, the υ-HF theory has been reconstructed on an affine Kac-Moody algebra along the soliton theory, using infinite-dimensional fermion. An infinite-dimensional fermion operator is introduced through a Laurent expansion of finite-dimensional fermion operators with respect to degrees of freedom of the fermions related to a υ-dependent potential with a Υ-periodicity. A bilinear equation for the υ-HF theory has been transcribed onto the corresponding τ-function using the regular representation for the group and the Schur-polynomials. The υ-HF SCF theory on an infinite-dimensional Fock space F∞ leads to a dynamics on an infinite-dimensional Grassmannian Gr∞ and may describe more precisely such a dynamics on the group manifold. A finite-dimensional Grassmannian is identified with a Gr

    Full Text Available A tese de medicina defendida em 1822, em Paris, por Antoine-Laurent Bayle, intitulada "Pesquisas sobre as doenças mentais", constitui um momento de virada na história das concepções biológicas em psicopatologia. Apoiado sobre um método anátomo-clínico rigoroso, Bayle apresenta seis observações clínicas de pacientes com uma história crônica e progressiva de comportamento exaltado, ideias de grandeza, de poder e de ambição que se transformam ao final de algum tempo em delírios maníacos com agitação psicomotora. Simultaneamente, vai-se instalando um quadro de paralisia progressiva de vários grupos musculares, chegando até à incapacidade física extrema. Na fase terminal, os pacientes apresentam uma condição tipicamente demencial e de profundo comprometimento corporal, que os conduz à morte. Ao exame cadavérico, Bayle constatou a presença sistemática de uma inflamação crônica das meninges cerebrais (aracnoidite crônica à qual ele atribui o fundamento biológico dos sintomas observados. Dessa forma, Bayle realiza uma descrição clínica rigorosa de uma entidade psicopatológica típica, de evolução crônica e progressiva e demonstra sua relação com uma lesão cerebral específica e objetivamente demonstrável. Tal descoberta, inicialmente recebida com muitas reservas, constituiria posteriormente uma espécie de paradigma para a pesquisa e para o projeto teórico e terapêutico para a psiquiatria biológica que começava a se organizar na França ao longo do século XIX.

  3. Multi-recycling of plutonium and incineration of americium, curium, and technetium in PWRs

    The future of nuclear power requires a clear strategy for radwaste and Plutonium management. Pressurized water reactors (PWR) and the associated fuel cycle installations represent the largest part of the French power plants (and are partly paid off). The reactors in service produce an annual 10 tons of Pu, 1.4 tons of minor actinides (MA), and 3.8 tons of long-lived fission products (LLFP). The spent fuel is reprocessed in La Hague plant to recover the energetic elements U and Pu. The latter was initially dedicated to power Fast Breeder Reactors that converted the depleted and reprocessed, thus ensuring a significant part of the French national energy resources. The shut-down of Super-Phenix, the postponement of building of Fast Breeder Reactors (FBR) and the relaxed need for stretching natural U resources raise the issue of Pu management. In fact, the Pu mono-recycling practiced in France since 1987 (St Laurent B1) only slows down the Pu accumulation in spent nuclear fuel, yet it is unable to stabilize the Pu inventory. Beyond the cooperation with its industrial partners, CEA investigates solutions for short and medium term Pu management thus contributing to research required for keeping nuclear power as an energy option. The range of these investigations shall cover both adaptations for light water reactors to facilitate Pu recycling and more innovative solutions concerning reactors, fuel and fuel cycle. The aim of using Pu more efficiently in PWR has led, not only for economic and non-proliferation reasons, but also for considerations related to the optimization of Pu and MA management. The mastery of Pu inventory is a requirement for all long-lived radwaste management methods. In this context, the potential of innovative PWRs has been investigated to control the Pu fluxes and to make them a milestone on the way to clean nuclear power. This paper presents the most recent results related to Pu utilization and MA and LLFP incineration like (Am+Cm) and Tc. To

Personal health records provide health information which can then be shared between multiple health care providers. Personal health records may also offer a tool for capturing patients' reported outcomes, thus enhancing their empowerment and improving communication with health care professionals. We conducted a pilot study to evaluate the usability of Sanoia, a freely accessible personal health record, which was customized for patients with the rare disease, idiopathic thrombocytopenic purpura (ITP.Methods: The Sanoia interface was expanded with ITP-specific tools. A prospective study was conducted at the referent center to evaluate the usability of this new interface (referred to here as the “tool” by patients. Forty-three patients were randomized into groups to use or to not use the tool. Its use was evaluated by a specific questionnaire and by surveying individual patient adherence profiles. Evaluation of health-related quality of life using the ITP patient assessment questionnaire, was performed at baseline and after 1, 3, and 6 months via postal mail.Results: The groups were similar at inclusion in terms of characteristics, including global quality of life. During the study period, the tool was used to update the personal records of 19/28 patients (68%, with a median of two connections to the tool (range 1–12 plus access by various health care professionals (n = 22.

    HBV and HCV play key roles in the etiopathogenesis of Hepatocellular carcinoma (HCC . Studies mostly based on cases from Western countries suggest distinct genetic pathways of carcinogenesis involving either TP53 or CTTNB1 mutations. Inappropriate reactivation of Wnt pathway due to mutations in CTNNB1 (Beta-Catenin gene itself is also frequently reported. Mutant Beta-catenin escapes to ubiquitination and down regulation by GSK3-B, it accumulates and trans-activates variety of oncogenes involved in neoplasmic transformation mimicking Wnt pathway activation. Taking into consideration viral infection, chromosome instability and TP53 /Beta-catenin alterations, Laurent-Puig et al. described two distinct HCC profiles in a serie of 137 HCC cases , the first one associates HBV infection with frequent chromosomal alteration and distributes with TP53 mutations, the second would be observed in HBV negative large sized tumors and distributes with Beta-catenin mutations. We have investigated the status of HBV and HCV infections and of genetic alterations in TP53 and CTTNB1 in 26 patients with HCC from Thailand. In tumours, HBV DNA was found in 19 cases (73% and HCV RNA in 4 cases (15.4% cases, 3 of whom were co-infected. Among the 19 HBV positive cases, sequencing of S gene showed genotype C in 82% and genotype B in 18%. Furthermore, 5/19 cases were negative for HBsAg and were categorized as occult HBV infections. TP53 mutations were detected in 9 cases (34,6% including 7 mutations at codon 249 (AGG to AGT, arginine to serine, considered as ";fingerprint"; of mutagenesis by aflatoxin metabolites. All cases with 249ser mutation had overt HBV infection.

    CTNNB1 mutations were found in 6/26 cases (23%, 4 of whom also had TP53 mutation. There was no significant association between CTTNB1

Fe-SP displayed selective cytotoxicity (IC50 at ∼1 μM against SKOV-3 and OVCAR-3 cell lines while Co-SP caused cytotoxic effects only at higher concentrations (IC50 at 60 μM and Cu-SP effects were negligible. High cytotoxicity of Mn-SP (30–60 μM appeared to be nonspecific because the Mn-chloride salt reduced cell viability similarly. The effect of Fe-SP at 1 μM proved to be ovarian cancer cell selective when compared to a panel of cell lines derived from different tumors. The first irreversible step in the induction of cell death by Fe-SP occurred after 3 hrs as indicated by the mitochondrial transmembrane potential (ΔΨm and was mainly linked to apoptotic, not necrotic events. To evaluate the toxicity of Fe-SP in vivo we conducted an acute toxicity study in rats. The LD50 of Fe-SP is >2000 mg/kg orally and >5.5 mg/kg body weight by intraperitoneal injection. An ovarian cancer animal model showed that the chemotherapeutic relevant dose of Fe-SP in rats is 0.5–1 mg/kg body weight. The present report suggests that Fe-SP is a

Mais concretamente, procurámos compreender a construção escolar que é feita pelos profissionais de ensino e pelos técnicos educativos sobre estes alunos, como é realizado o trabalho de diagnóstico e intervenção quotidiana sobre os mesmos, bem como identificar os acordos e desacordos existentes entre os professores e os técnicos quando estes justificam e defendem o seu ponto de vista sobre a melhor forma de intervir sobre cada caso. A abordagem teórica privilegiada é a sociologia pragmática de Luc Boltanski e Laurent Thévenot, que nos permite perceber como os atores sociais experienciam as situações em que estão envolvidos, concebendo-os como competentes e capazes de emitir pontos de vista críticos para ajuizar situações e expressar os seus sentimentos de (injustiça. Os principais resultados, obtidos nesta pesquisa, refletem um aumento dos diagnósticos desta patologia, existindo contudo algumas dúvidas na qualidade e fiabilidade dos mesmos. Foi possível concluir igualmente que a perceção dos professores se altera quando o aluno é diagnosticado, praticando-se uma inclusão escolar depois da exclusão e da construção de uma identidade deteriorada no contexto da sala de aula. Relativamente às formas de tratamento desta patologia no contexto escolar registaram-se algumas críticas ferozes à comunidade cientifica pela inexistência de consensos e definição do que é um aluno hiperativo e/ou com défice de atenção. Em relação à sua relevância social e científica, este estudo permite uma compreensão mais alargada da realidade em que estes jovens vivem no contexto escolar, sendo útil tanto para professores, como para técnicos educativos, familiares com filhos com o mesmo problema e para investigadores que se dediquem à problem

  9. Flow structure at an ice-covered river confluence

    River confluences are known to exhibit complex relationships between flow structure, sediment transport and bed-form development. Flow structure at these sites is influenced by the junction angle, the momentum flux ratio (Mr) and bed morphology. In cold regions where an ice cover is present for most of the winter period, the flow structure is also likely affected by the roughness effect of the ice. However, very few studies have examined the impact of an ice cover on the flow structure at a confluence. The aims of this study are (1) to describe the evolution of an ice cover at a river confluence and (2) to characterize and compare the flow structure at a river confluence with and without an ice cover. The field site is a medium-sized confluence (around 40 m wide) between the Mit is and Neigette Rivers in the Bas-Saint-Laurent region, Quebec (Canada). The confluence was selected because a thick ice cover is present for most of the winter allowing for safe field work. Two winter field campaigns were conducted in 2015 and 2016 to obtain ice cover measurements in addition to hydraulic and morphological measurements. Daily monitoring of the evolution of the ice cover was made with a Reconyx camera. Velocity profiles were collected with an acoustic Doppler current profiler (ADCP) to reconstruct the three-dimensional flow structure. Time series of photographs allow the evolution of the ice cover to be mapped, linking the processes leading to the formation of the primary ice cover for each year. The time series suggests that these processes are closely related with both confluence flow zones and hydro-climatic conditions. Results on the thickness of the ice cover from in situ measurements reveal that the ice thickness tends to be thinner at the center of the confluence where high turbulent exchanges take place. Velocity measurements reveal that the ice cover affects velocity profiles by moving the highest velocities towards the center of the profiles. A spatio

    Full Text Available Jay Waldron1, Althea McCourty1, Laurent Lecanu1,21The Research Institute of the McGill University Health Centre, Montreal, Canada; 2Department of Medicine, McGill University, Quebec, CanadaPurpose: Neural stem cell (NSC transplantation and pharmacologic activation of endogenous neurogenesis are two approaches that trigger a great deal of interest as brain repair strategies. However, the success rate of clinical attempts using stem cells to restore neurologic functions altered either after traumatic brain injury or as a consequence of neurodegenerative disease remains rather disappointing. This suggests that factors affecting the fate of grafted NSCs are largely understudied and remain to be characterized. We recently reported that aging differentially affects the neurogenic properties of male and female NSCs. Although the sex steroids androgens and estrogens participate in the regulation of neurogenesis, to our knowledge, research on how gender-based differences affect the capacity of NSCs to differentiate and condition their neural fate is lacking. In the present study, we explored further the role of cell sex as a determining factor of the neural fate followed by differentiating NSCs and its relationship with a potential differential expression of aromatase (CYP19, the testosterone-metabolizing enzyme.Results: Using NSCs isolated from the subventricular zone of three-month-old male and female Long-Evans rats and maintained as neurospheres, we showed that differentiation triggered by retinoic acid resulted in a neural phenotype that depends on cell sex. Differentiated male NSCs mainly expressed markers of neuronal fate, including ßIII-tubulin, microtubule associated protein 2, growth-associated protein 43, and doublecortin. In contrast, female NSCs essentially expressed the astrocyte marker glial fibrillary acidic protein. Quantification of the expression of aromatase showed a very low level of expression in undifferentiated female NSCs

    The Rossendorf Beamline (ROBL) - located at BM20 of the European Synchrotron Radiation Facility (ESRF) in Grenoble, France - is in operation since 1998. This 7th report covers the period from January 2009 to December 2010. In these two years, 67 peer- reviewed papers have been published based on experiments done at the beamline, more than in any biannual period before. Six highlight reports have been selected for this report to demonstrate the scientific strength and diversity of the experiments performed on the two end-stations of the beamline, dedicated to Radiochemistry (RCH) and Materials Research (MRH). The beamtime was more heavily overbooked than ever before, with an acceptance rate of only 25% experiments. We would like to thank our external proposal review members, Prof. Andre Maes (KU Leuven, Belgium), Prof. Laurent Charlet (UJF Grenoble, France), Dr. Andreas Leinweber (MPI Metallforschung, Stuttgart, Germany), Prof. David Rafaja (TU Bergakademie Freiberg, Germany), Prof. Dirk Meyer (TU Dresden, Germany), who evaluated the inhouse proposals in a thorough manner, thereby ensuring that beamtime was distributed according to scientific merit. The period was not only characterized by very successful science, but also by intense work on the optics upgrade. In spring 2009, a workshop was held at ROBL, assembling beamline experts from German, Spanish and Swiss synchrotrons, to evaluate the best setup for the new optics. These suggestions was used to prepare the call for tender published in July 2009. From the tender acceptance in November 2009 on, a series of design review meetings and factory acceptance tests followed. Already in July 2010, the first piece of equipment was delivered, the new double-crystal, double-multilayer monochromator. The disassembly of the old optics components started end of July, 2011, followed by the installation of the new components. As of December 2011, the new optics have seen the first test beam and thorough hot commissioning will

    A Gram-stain-negative, aerobic, rod-shaped, non-spore-forming bacterium (ChimEc512(T)) was isolated from 56 host seedlings of the hyperaccumulating Anthyllis vulneraria legume, which was on an old zinc mining site at Les Avinières, Saint-Laurent-Le-Minier, Gard, South of France. On the basis of 16S rRNA gene sequence similarities, strain ChimEc512(T) was shown to belong to the genus Rhizobium and to be most closely related to Rhizobium endophyticum CCGE 2052(T) (98.4%), Rhizobium tibeticum CCBAU 85039(T) (98.1%), Rhizobium grahamii CCGE 502(T) (98.0%) and Rhizobium mesoamericanum CCGE 501(T) (98.0%). The phylogenetic relationships of ChimEc512(T) were confirmed by sequencing and analyses of recA and atpD genes. DNA-DNA relatedness values of strain ChimEc512(T) with R. endophyticum CCGE 2052(T), R. tibeticum CCBAU 85039(T), R. mesoamericanum CCGE 52(T), Rhizobium grahamii CCGE 502(T), Rhizobium etli CCBAU 85039(T) and Rhizobium radiobacter KL09-16-8-2(T) were 27, 22, 16, 18, 19 and 11%, respectively. The DNA G+C content of strain ChimEc512(T) was 58.9 mol%. The major cellular fatty acid was C18 : 1ω7c, characteristic of the genus Rhizobium . The polar lipid profile included phosphatidylethanolamine, phosphatidylmonomethylethanolamine, phosphatidylglycerol and phosphatidylcholine and moderate amounts of aminolipids, phospholipid and sulfoquinovosyl diacylglycerol. Although ChimEc512(T) was able to nodulate A. vulneraria, the nodC and nifH genes were not detected by PCR. The rhizobial strain was tolerant to high concentrations of heavy metals: up to 35 mM Zn and up to 0.5 mM Cd and its growth kinetics was not impacted by Zn. The results of DNA-DNA hybridizations and physiological tests allowed genotypic and phenotypic differentiation of strain ChimEc512(T) from species of the genus Rhizobium with validly published names. Strain ChimEc512(T), therefore, represents a novel species, for which the name Rhizobium metallidurans sp. nov. is proposed, with the type strain

    Oxygen (δ18O) and strontium (87Sr/86Sr) isotopes were used as tools to investigate human migration at the early Bell Beaker site (2500-2000 BC) Le Tumulus des Sables, Saint-Laurent-Médoc, south-west France. The O and Sr isotope ratios measured in tooth enamel record the average dietary isotope signature ingested by that individual during their childhood. When this data is compared to the isotope signature of the burial site it can be used to indicate if the individual migrated into this area during their lifetime. The O isotopic composition of meteoric water changes depending on climate, temperature and quantity of precipitation. O isotope ratios in skeletal and dental remains are related to body water, which in turn is influenced by diet, physiology and climate. Most of the water consumed by large mammals comes from drinking water, typically sourced locally. Sr isotope ratios on the other hand vary between different geologic regions, depending on their age and composition. Sr is released through weathering and transported into the soil, ground and surface water, where it becomes available for uptake by plants, enters the food cycle and eventually ends up in skeletal and dental tissue where it substitutes for calcium. We analysed the teeth of 18 adult and 8 juvenile disarticulated skeletons from Le Tumulus des Sables. O isotopes were analysed in-situ by Sensitive High Resolution Ion Micro Probe (SHRIMP).The Sr isotope analysis involved drilling a 0.2-0.5 mg sample of enamel from the tooth. The Sr was then chemically separated and analysed by Thermal Ionization Mass Spectrometry (TIMS). These results were then compared to the O isoscape of Europe and bioavailable Sr isotope data (fauna, plants, soils) from the IRHUM database. We found that most of the individuals at Le Tumulus des Sables show O and Sr isotope ratios corresponding to the local environmental signal and we interpret these as part of the local population. 3 adults however show slightly higher 87Sr/86

However, the heterogeneity of responses observed in immuno-oncology (I-O suggests that new approaches may be appropriate to reflect disease dynamics meaningfully. Materials and methods: This study explored the impact of incorporating immune-specific health states into economic models of I-O therapy. Two variants of the PSM and a Markov model were populated with data from one clinical trial in metastatic melanoma patients. Short-term modeled outcomes were benchmarked to the clinical trial data and a lifetime model horizon provided estimates of life years and quality adjusted life years (QALYs. Results: The PSM-based models produced short-term outcomes closely matching the trial outcomes. Adding health states generated increased QALYs while providing a more granular representation of outcomes for decision making. The Markov model gave the greatest level of detail on outcomes but gave short-term results which diverged from those of the trial (overstating year 1 progression-free survival by around 60%. Conclusion: Increased sophistication in the representation of disease dynamics in economic models

  15. On the Nature of the Compact Object in SS 433. Observational Evidence of X-Ray Photon Index Saturation

    2010-01-01

    We present an analysis of the X-ray spectral properties observed from black hole , candidate (BHC) binary SS 433. We have analyzed Rossi X-ray Time Explorer (RXTE) data from this source, coordinated with Green Bank Interferometer/RATAN-600. We show that SS 433 undergoes a X-ray spectral transition from the low hard state (LHS) to the intermediate state (IS). We show that the X-ray broad-band energy spectra during all spectral states are well fit by a sum of so called "Bulk Motion Comptonization (BMC) component" and by two (broad and narrow) Gaussians for the continuum and line emissions respectively. In addition to these spectral model components we also find a strong feature that we identify as a" blackbody-like (BB)" component which color temperature is in the range of 4-5 keV in 24 IS spectra during the radio outburst decay in SS 433. Our observational results on the "high temperature BB" bump leads us to suggest the presence of gravitationally redshifted annihilation line emission in this source. In fact this spectral feature has been recently reproduced in Monte Carlo simulations by Laurent and Titarchuk. We have also established the photon index saturation at about 2.3 in index vs mass accretion correlation. This index-mass accretion correlation allows us to evaluate the low limit of black hole (BH) mass of compact object in SS 433, M(sub bh) approximately > 2 solar masses, using the scaling method using BHC GX 339-4 as a reference source. Our estimate of the BH mass in SS 433 is consistent with recent BH mass measurement using the radial-velocity measurements of the binary system by Hillwig & Gies who find that M(sub x)( = (4.3 +/- 0.8) solar masses. This is the smallest BH mass found up to now among all BH sources. Moreover, the index saturation effect versus mass accretion rate revealed in SS 433, like in a number of other BH candidates, is the strong observational evidence for the presence of a BH in SS 433.

Physics theory suggests that the interaction between a non-coring needle (NCN, made of stainless steel and a plastic base would lead to the stronger material (steel altering the more malleable material (plastic. Objectives: To investigate whether needle impacts can alter a plastic base’s surface, thus potentially reducing flushing efficacy. Study design and methods: A Port made of POM was punctured 200 times with a 19-gauge NCN. Following the existing guidelines, the needle tip pricked the base with each puncture. The Port’s base was then examined using a two-dimensional optical instrument, and a bi-dimensional numerical simulation using COMSOL® was performed to investigate potential surface irregularities and their impact on fluid flow. Results: Each needle impact created a hole (mean depth, 0.12 mm with a small bump beside it (mean height, 0.02 mm the Reynolds number Rek≈10. A numerical simulation of the one hole/bump set showed that the flushing efficacy was 60% that of flushing along a flat surface. Discussion: In clinical practice, the number of times a Port is punctured depends on patient and treatment characteristics, but each needle impact on the plastic base may increase the risk of decreased flushing effectiveness. Therefore, the more a plastic Port is accessed, the greater the risk of microorganisms, blood products, and medication accumulation. Conclusions: Multiple needle impacts created an irregular surface on the Port’s base, which decreased flushing efficacy

    French Guiana is a French overseas territory with a rich history of migration that has led to a highly intercultural society. Today, its population is one of the youngest in the French territory and is rapidly increasing. Despite a context of cultural revival seeking "tradition", a distanced baseline of local practices is still lacking. This work addresses some aspects of the cultural hybridizations in progress in urban areas. Semi directed interviews were conducted with willing participants aged between 18 and 40. Interviews took place in French Guiana's two main urban centres: Cayenne and Saint Laurent du Maroni. People were interviewed about the last medicinal plant they used in the preceding year. Due to the high use of plant baths in French Guiana, a focus was made on baths. Eighty-three people answered: 43 women and 40 men (mean age of 28.7 years old). In total, 226 remedies were counted in our study, 155 single plant remedies and 71 compound remedies leading to 316 use reports of plants from 16 cultural groups. A surprising number of 108 botanical species were recorded. Eighty-one recipes for baths were also collected. Despite this high citation rate, a rather low proportion of people declare a systematic and regular recourse upon local pharmacopoeia (46%; 38/83). Although many interviewees used plants, far from the majority used them on a regular basis. In practice, 50% of the species (54/108 spp.; 99/316 URs) are non-native but domesticated exotic species, imported from Asia, Europe, Africa or remote parts of America, either during colonization, the slave trade era, or more recently with the latest migrations. Although phytotherapy use is often thought to be related to countryside dwellers and older people, medicinal plants seem to play an important role in the lives of urban French Guianese youth. Research shows a large diversity of medicinal species used linked with the great cultural diversity of the Guianese cities. One characteristic of this

However, a normal liver stiffness could rule out hepatic causes of ascites at an early stage. The aim of the present study was to determine whether liver stiffness can be generally determined by transient elastography through an ascites layer, to determine whether the ascites-mediated increase in intra-abdominal pressure affects liver stiffness, and to provide initial data from a pilot cohort of patients with various causes of ascites.Methods and results: Using the XL probe in an artificial ascites model, we demonstrated (copolymer phantoms surrounded by water that a transient elastography-generated shear wave allows accurate determination of phantom stiffness up to a water lamella of 20 mm. We next showed in an animal ascites model that increased intra-abdominal pressure does not affect liver stiffness. Liver stiffness was then determined in 24 consecutive patients with ascites due to hepatic (n = 18 or nonhepatic (n = 6 causes. The cause of ascites was eventually clarified using routine clinical, imaging, laboratory, and other tools. Valid (75% or acceptable (25% liver stiffness data could be obtained in 23 patients (95.8% with ascites up to an ascites lamella of 39 mm.

    Over the past few years, substantial clinical data have been presented showing that incretin-based therapies are effective glucose-lowering agents. Specifically, glucagon-like peptide 1 receptor agonists demonstrate an efficacy comparable to insulin treatment with minimal hypoglycemia and have favorable effects on body weight. Thus, many of the unmet clinical needs noted from prior therapies are addressed by these agents. However, even after many years of use, many continue to raise concerns about the long-term safety of these agents and, in particular, the concern with pancreatitis. This clearly remains a complicated topic. Thus, in this issue of Diabetes Care, we continue to update our readers on this very important issue by presenting two studies evaluating incretin-based medications and risk of pancreatitis. Both have undergone significant revisions based on peer review that provided significant clarification of the data. We applaud both author groups for being extremely responsive in providing the additional data and revisions requested by the editorial team. As such, because of the critical peer review, we feel both articles achieve the high level we require for Diabetes Care and are pleased to now present them to our readers. In keeping with our aim to comprehensively evaluate this topic, we asked for additional commentaries to be prepared. In the narrative outlined below, Prof. Edwin A.M. Gale provides a commentary on the report that focuses on clinical trials of liraglutide in the treatment of diabetes. In the narrative that follows Prof. Gale's contribution, Dr. Laurent Azoulay provides a commentary about the remaining uncertainty in this area and also discusses the results from a nationwide population-based case-control study. From the journal's perspective, both of the articles on pancreatitis and incretin-based therapies reported in this issue have been well vetted, and we feel both of the commentaries are insightful. © 2015 by the American Diabetes

  2. Multi-Hadron Observables from Lattice Quantum Chromodynamics

    We describe formal work that relates the nite-volume spectrum in a quantum eld theory to scattering and decay amplitudes. This is of particular relevance to numerical calculations performed using Lattice Quantum Chromodynamics (LQCD). Correlators calculated using LQCD can only be determined on the Euclidean time axis. For this reason the standard method of determining scattering amplitudes via the Lehmann-Symanzik-Zimmermann reduction formula cannot be employed. By contrast, the nite-volume spectrum is directly accessible in LQCD calculations. Formalism for relating the spectrum to physical scattering observables is thus highly desirable. In this thesis we develop tools for extracting physical information from LQCD for four types of observables. First we analyze systems with multiple, strongly-coupled two-scalar channels. Here we accommodate both identical and nonidentical scalars, and in the latter case allow for degenerate as well as nondegenerate particle masses. Using relativistic eld theory, and summing to all orders in perturbation theory, we derive a result relating the nite-volume spectrum to the two-to-two scattering amplitudes of the coupled-channel theory. This generalizes the formalism of Martin L uscher for the case of single-channel scattering. Second we consider the weak decay of a single particle into multiple, coupled two-scalar channels. We show how the nite-volume matrix element extracted in LQCD is related to matrix elements of asymptotic two-particle states, and thus to decay amplitudes. This generalizes work by Laurent Lellouch and Martin L uscher. Third we extend the method for extracting matrix elements by considering currents which insert energy, momentum and angular momentum. This allows one to extract transition matrix elements and form factors from LQCD. Finally we look beyond two-particle systems to those with three-particles in asymptotic states. Working again to all orders in relativistic eld theory, we derive a relation between the

    It is necessary to identify the environment responsible for IGA and IGSCC in order to understand and prevent corrosion on the secondary side of the steam generators. For this purpose, physico-chemical analyses of deposits and underlying surfaces have been performed. Chemical analyses were carried out on the deposits present on the free span and on the non corroded and corroded restricted flow areas on more than 340 pulled out tubes. Surfaces analyses were performed on two tubes pulled form Saint Laurent B1, SG, 2. The results of the examination are discussed and compared to laboratory tests to determine the role of the deposit in the corrosion process. Degradation occurred only on restricted flow areas where, compared to free span, silicate compounds were deposited with an aluminum-silicate gel sublayer more or less bonded to organic compounds. Under this gel, a chromium and iron made non-protective brittle layer was observed at the interface with the matrix. It appears that the copper and zinc species along with iron oxides located in free and restricted flow areas increase the tube degradation by favoring the oxidation of the organic species. These oxidised compounds can then be bound to metallic elements such as chromium. Hence, a higher content of copper and zinc species are found in the degraded zone of the restricted flow area. Unlike what was found in the past, the harmful effect of alkali metals (Na + and K + ) on alloy 600 has not been observed. In this work, the harmful effect of Pb has been confirmed. More work is required to establish the role of As compounds found near the crack and grain boundaries. These results will lead the utilities to decrease the concentration of these elements in the secondary water either by purifying the water on by reducing the corrosion products coming from the copper alloy condensers. Complementary analyses will be performed on more pulled out tubes from other plants along with laboratory simulations to confirm these early

    Following the Fukushima-Daichi accident, several actions have been taken in France from the lessons learnt from the accident: the elaboration of a national plan for the management of a major nuclear or radiological accident, and the safety complementary evaluations to be carried out by nuclear operators. As a complement to the measures to be implemented for the protection of the overall population in emergency radiological situation, the protection of workers mobilized for the management of the crisis has also to be taken into account in the framework of these measures. The French Society of Radiation Protection (SFRP) has organized a technical day to take stock of this question. The program comprises 4 topical sessions dealing with: the main actions taken at the national scale after the Fukushima-Daichi accident, the strategies and intervention means of nuclear operators in case of radiological emergency, the radiation protection R and D for the protection of intervenors in case of radiological emergency, and the main actions implemented at the international scale and their perspectives. This document brings together the abstracts and the presentations (slides) of the different talks given at the meeting: 1 - Health status and lessons learnt from the Fukushima accident - workers (Alain RANNOU, IRSN); 2 - National response plan to a major nuclear or radiologic accident (Eric GOSSET, SGDSN); 3 - Legal framework applicable to intervenors (Thierry LAHAYE, DGT); 4 - Prescriptions linked with complementary safety and liability studies (Laurent FOUCHER, ASN); 5 - EDF: radiological risk management in emergency situation (Pascal BOUCHERY, EDF); 6 - CEA: intervention strategy, means and radiation protection (Xavier PECTORIN, Laurence FUSIL - CEA); 7 - AREVA: FINA's Intervention and workers' radiation protection (Bruno ADHEMAR, Patrick DEVIN - AREVA); 8 - Intervention in radiological emergency situation: the INTRA (Robots intervention on accidents) economic

A group of buprenorphine office-based practice prescribers was selected to participate in this study. They were asked to screen for inclusion all their patients coming for a visit from February to August 2002. Once included by their prescribing physician, patients were given a series of self-administered questionnaires to be returned directly to the research staff, independently of their prescriber. Each prescriber was given a questionnaire to complete based on their knowledge and interview of the patient. Items assessed were history of current treatment, current substance use, buprenorphine treatment related behavior (daily frequency of intake, route of administration, benzodiazepine use and existence of a major depressive episode. Prescribers and patients’ questionnaires were compared. Concordance of both assessments was assessed by kappa statistics. The sensitivity and specificity as well as the positive and negative predictive values of prescriber collected information were compared to that of their patients’. There was an overall good correlation between both data sources on the procedures for buprenorphine use especially for intravenous use of buprenorphine. There were important

    Full Text Available This study evaluated the physical properties and oil extraction from grape seeds from three white (Welschriesling, Green Veltliner, Hibernal and two red (Zweigelt and Saint Laurent must varieties of grapevine by cold screw pressing as the appropriate extraction process. Pressing was carried out by a screw press UNO FM 3F by Farmet Company, Czech Republic. The pressing device consists of a matrix, 220 mm screw, head, heating mantle, nozzle holder, and a nozzle of 10 mm in diameter. The minimal and maximal screw rotation speeds were chosen within the press characteristics in order to achieve a correct expression and to avoid press overload. For successful pressing of the seeds and their storage, their initial moisture content was lowered from 40 to 45% to about 5 to 8% in a chamber dryer. The temperature in the chamber dryer did not exceeded 40 °C. Seeds of all varieties were pressed at the same speeds of 20, 40, 60, and 80 rpm. The characteristics of the grape seeds are as follows: The density ranges from 602.7 to 606.3 kg.m-3, thousand seeds weigh is between 21.9 - 26.6 g, humidity between 5.6 - 7.1% of dry matter and seed oil content, determined by extraction and depending on the variety, ranges from 15.3 to 17.5% in dry basis. The results have confirmed that when the screw rotation speed is changed from 20 to 80 rpm, the press capacity increases on average from 0.84 kg.h-1 to 1.75 kg.h-1, but simultaneously the oil yield reduces from 9.85 to 6.75%. This means that one kilogram of seed may produce 67.5 to 98.5 g of oil. The quantity of the pressed oil ranges from 67.5 to 98.5 g.kg-1 and thus depends on the variety. The measured results can be used in commercial practice for optimizing the pressing process for pressing of oil from grape seeds.

    This is the proceedings of the 2. parliamentary gathering on energy held on 14 October 1999. The document presents the talks by Mr Michel Destot (as special rapporteur of the Industry's budget in National Assembly) and Laurent Fabius, President of National Assembly, and Jean-Claude Gayssot, Minister of Equipment, Transport and Dwelling, at the opening session, three round tables, the colloquium synthesis and the closing session. The round tables addressed the following issues: - 1. International and long-term approach guided predominantly by energy demand; - 2. Energy solutions in the struggle against greenhouse effect; - 3. Challenges of opening the European energy market (internationalization and decentralization). At the first round table, Yves Martin, President of the technical section of General Council of Mines, structured his introductory report emphasizing the specific issues of three time horizons: the present, characterized by abundant energy offer; the horizon of 10 to 20 years, that of the energy suppliers which is orienting their investments; the horizon of more than half a century, corresponding to responses of far-reaching actions imposed by energy demand and which must be the object of governments' policies. Jean-Yves Le Deaut, deputy of Meurthe-et-Moselle discussed the risks of climate change, resources' exhaustion, nuclear power and the issue of developing the renewable energies. The problems raised by energy demand by the year 2050 to met the needs of an earth population of 9 billions were mentioned by Philippe Trepant, the president of French Union of oil industries. Energy problems from a globalization standpoint were discussed also by Benjamin Dessus, Director of Ecodev program of CNRS. Policy in the field of mastering greenhouse gas releases was mentioned in the talk by Michel Mousel, president of Inter-ministerial Mission for greenhouse effect. In the frame of 2. round table questions relating to energy management, renewable

Among the three types of liposomes developed, anionic liposomes provided the best results in terms of encapsulation efficiency (56% and enzymatic protection against trypsin (20.6% vs 0% for ghrelin alone and carboxylesterase (81.6% vs 17.2% for ghrelin alone. Ghrelin presented both electrostatic and hydrophobic interactions with the anionic lipid bilayer, as demonstrated by isothermal titration calorimetry. Then, anionic liposomes were coated with N-(2-hydroxypropyl-3-trimethyl ammonium chitosan chloride. The coating involved a size increment from 146.9±2.7 to 194±6.1 nm, for uncoated and coated liposomes, respectively. The ζ-potential was similarly increased from -0.3±1.2 mV to 6±0.4 mV before and after coating, respectively. Chitosan provided mucoadhesion, with an increase in mucin adsorption of 22.9%. Enhancement of permeation through the Calu3 epithelial monolayer was also observed with 10.8% of ghrelin recovered in the basal compartment in comparison to 0% for ghrelin alone. Finally, aerosols generated from two nasal devices (VP3 and SP270 intended for aqueous dispersion were characterized with either coated or uncoated liposomes. Contrarily to the SP270 device, VP3 device showed minor changes between coated and uncoated liposome aerosols, as shown by their median volume diameters of 38.4±5.76 and 37.6±5.74 µm, respectively.

    The world's fast reactor community met in Paris in March 2013 to explore new opportunities in the development of fast reactor and related fuel cycles. Fast reactor technology has the potential to ensure that energy resources, which would run out in a few hundred years using today's technology, will actually last several thousand years. Fast reactors also reduce the volume and toxicity of the final waste. The IAEA has been supporting fast reactors technology and providing a forum for international cooperation. The most important event dedicated to this technology is the International Conference on Fast Reactors and Related Fuel Cycles organized by the IAEA and held every four years since 2009, when Japan hosted the conference in Kyoto (FR09). Four years later, almost 700 experts from 34 countries and 3 international organizations gathered in Paris on 4-7 March 2013 for the International Conference on Fast Reactors and Related Fuel Cycles: Safe Technologies and Sustainable Scenarios (FR13). 'The IAEA remains the unique collaboration forum for ensuring continued progress in fast reactor technology', said IAEA Director General Yukiya Amano in a video opening address. 'We provide an umbrella for knowledge preservation, information exchange and collaborative R and D in which resources and expertise are pooled', Mr Amano added. 'Promising innovation routes are now clearly identified to further enhance safety, reduce capital cost and improve efficiency, reliability and operability, making the Generation IV sodium fast reactor concept an attractive option for electricity production', said Laurent Michel, Director General, French Ministry of Ecology, Sustainable Development and Energy, in his opening remarks. Main advances in the key areas of technological development were presented during the 41 technical sessions of the conference, including advances in fast reactors and fuel cycles technology, safety, and economic and proliferation resistance related issues.

    In recent decades, substantial experimental research efforts have been devoted to linear and nonlinear physical phenomena. In particular, studies of integrable nonlinear equations in solitary waves theory have attracted intensive interest from mathematicians, with the principal goal of fostering the development of new methods, and physicists, who are seeking solutions that represent physical phenomena and to form a bridge between mathematical results and scientific structures. The aim for both groups is to build up our current understanding and facilitate future developments, develop more creative results and create new trends in the rapidly developing field of solitary waves. The notion of the integrability of certain partial differential equations occupies an important role in current and future trends, but a unified rigorous definition of the integrability of differential equations still does not exist. For example, an integrable model in the Painlevé sense may not be integrable in the Lax sense. The Painlevé sense indicates that the solution can be represented as a Laurent series in powers of some function that vanishes on an arbitrary surface with the possibility of truncating the Laurent series at finite powers of this function. The concept of Lax pairs introduces another meaning of the notion of integrability. The Lax pair formulates the integrability of nonlinear equation as the compatibility condition of two linear equations. However, it was shown by many researchers that the necessary integrability conditions are the existence of an infinite series of generalized symmetries or conservation laws for the given equation. The existence of multiple soliton solutions often indicates the integrability of the equation but other tests, such as the Painlevé test or the Lax pair, are necessary to confirm the integrability for any equation. In the context of completely integrable equations, studies are flourishing because these equations are able to describe the

    Full Text Available Pour Albert Ogien et Louis Quéré, les sciences sociales sont séparées des sciences de la vie par une frontière quasi-infranchissable. Par conséquent, selon eux, l’évocation de vues empruntées à la biologie en sociologie et en anthropologie serait, au mieux, dépourvue d’intérêt, au pire fallacieuse. Ils développent cette thèse en invoquant, notamment, la non-falsifiabilité des sciences sociales par les sciences de la vie, le poids du social et de l’environnement dans la cognition et l’action humaines, ou encore l’irréductibilité des objets respectifs de ces disciplines. Nier l’existence d’une telle frontière impliquerait, à leurs yeux, la dissolution des sciences sociales dans les sciences de la nature. Certains arguments invoqués à l’appui de ces thèses valent pour réfuter certaines formes sommaires de naturalisme. Toutefois, ils n’invalident pas les variantes comme celles que proposent Laurence Kaufmann et Laurent Cordonier. Contrairement à ce que suggèrent ces arguments, on peut fort bien défendre le principe d’une autonomie épistémologique des sciences sociales, tout en contestant l’existence d’une frontière nette entre disciplines. Par ailleurs, l’hypothèse de la frontière fragilise les sciences sociales, en les conduisant à ignorer un champ de recherche dans lequel elles ont pourtant vocation à intervenir : celui de l’articulation des connaissances qu’elles accumulent, de manière indépendante et au moyen de leurs propres méthodes, avec celles que recueillent, de leur côté, les sciences de la vie.

This dataset contains daily homogenised surface temperature observations for 112 locations around Australia, dating back to 1910. An ontology for the dataset was developed [Lefort et. al., 2012], based on the existing Semantic Sensor Network ontology [Compton et. al., 2012] and the W3C RDF Data Cube vocabulary [W3C, 2012]. Additional vocabularies were developed, e.g. for BoM weather stations and rainfall districts. The dataset was converted to RDF and loaded into an RDF triplestore. The Linked-Data API (http://code.google.com/p/linked-data-api) was used to configure specific URI query patterns (e.g. for observation timeseries slices by station), and a SPARQL endpoint was provided for direct querying. In addition, some demonstration 'mash-ups' were developed, providing an interactive browser-based interface to the temperature timeseries.

Several model simulations were run with dust RRTM longwave and shortwave radiative feedback switched on or off, with dust vertical flux after Marticorena and Bergametti [1995] or after Alfaro and Gomez [2001], including viscous sublayer approach [Janjic, 1994] applied or not, and with or without preferential sources following Ginoux [2001]. Additionally, two new observational datasets of surface "aeolian" roughness length [Laurent, 2006; Prigent, 2005] are applied either for drag partition correction, or as substitution for the empirical model roughness length. These simulations are compared with detailed observational data. The atmospheric wind field is analyzed in terms of its capability to reproduce the low level jet in the Bodélé. References: Alfaro, S.

    2011-11-01

    Under the management of Silvain Ikazaki who organised Atoms for the Future 2011, the conferences have taken place in Paris, at ENSTA Paris Tech engineering school. It was Isabelle Tanchou, ENSTA, Deen of Education and Research who opened the two days of conferences of Atoms for the Future 2011 on the fuel cycle in front of more than a hundred young professionals coming from all Europe, Sri Lanka, Japan.. Then Laurent Stricker, chairman of WANO detailed the consequences of the Fukushima accident on nuclear industry and safety and which role the WANO was playing in this current situation. Jean-Pierre Gros, Areva executive vice-president of recycling business unit and CEO of MELOX facility, explained the reprocessing and recycling of used fuels through La Hague and MELOX operation. He specified that 96% of a used fuel is recyclable although most of used fuel is today stored in pools. This presentation was completed by the operator point of view of the nuclear fuel cycle given by Michel Pays, EDF director of strategy and risks at the nuclear fuel department. Georges Capus, Areva vice president marketing Frond End, explained the strategic, economic and political considerations of this activity. The afternoon conferences continued with the intervention of Bernard Boullis, CEA director nuclear fuel cycle back-end programs. He gave us an overview of the future nuclear fuel cycles detailing fast reactors examples such as ASTRID, ALLEGRO.. Radioactive materials need a safe, secure and efficient transport: it was the theme Michel Hartenstein, World Nuclear Transport Institute director. He illustrated his presentation with a very impressive video of the different qualification tests a canister has to undergo. The first day of lectures was closed by Gerald Ouzounian, ANDRA director of International Division. He exposed the radioactive waste management in France, describing the classification of those wastes depending on the radioactivity level, the existing sites, the current

    Laurent Henninger

    2005-04-01

    Full Text Available Laurent Henninger intervenant sur les « révolutions militaires » (notion située au carrefour du débat historique lancé dans les années 1980 par Geoffrey Parker – en polémique avec Jeremy Black – et du débat stratégique américain dans les années 1990 souligne que les avancées dans l’art de la guerre ont été depuis cinq siècles une des composantes majeures de la barbarisation et du totalitarisme. La notion de « révolution militaire » est aujourd’hui contestée par ceux qui y voient un outil interprétatif de trop longue durée et lui préfèrent l’idée de « mutations militaires » (selon laquelle l’accumulation de changements millimétriques sur la longue durée débouche sur des ruptures. Après avoir passé en revue la première révolution militaire – XVe-XVIIe siècles – fondée sur la mise à distance de la cavalerie grâce à l’infanterie nouvelle, à l’artillerie du champ de bataille, Henninger s’interroge sur le critère discriminant pour qualifier les nouvelles guerres de la Renaissance (l’hyperviolence n’en est pas un à ses yeux et voit dans les armes à feu la vraie rupture car elles influent de façon radicale sur la peur et le courage des combattants et sont source d’une véritable « inhumanité » dans la mesure où leur feu est « imparable ». Il insiste sur l’émergence d’un nouveau type de courage guerrier non archaïque et plus « stoïcien » marqué par l’acceptation de la mort. Dans cette perspective, l’« inhumanisation » technique porterait en elle la possibilité de la barbarisation. L. Henninger développe ensuite cette thèse à partir de l’examen des guerres mécanisées de la période 1860-1950 en s’attardant sur la guerre de Sécession puis sur la Grande Guerre. Il relie aussi la question du totalitarisme à la réflexion sur les « bombardements stratégiques massifs » et les débuts de la dissuasion nucléaire (terme qui ne s

    L'objectif de cette etude est d'elaborer un processus decisionnel a reference spatiale (PDRS) pour la mariculture. Le PDRS est applique aux eaux cotieres de la baie des Chaleurs, dans le golfe du Saint-Laurent (Canada). Une carte preliminaire regionale d'indices du potentiel maricole, d'une limite de resolution spatiale de 1 kmsp2, est produite avec des parametres du niveau 1. Ces parametres englobent la temperature de l'eau de surface, extraite des images AVHRR, la salinite, les courants ainsi que les pigments chlorophylliens, quantifies a l'aide de mesures in situ. Les images AVHRR, prises en 1994, ont ete utiliees comme reference primaire pour selectionner des aires pouvant supporter une activite maricole sur la cote nord de la baie des Chaleurs. La temperature de surface extraite de ces images permet une analyse mesoechelle a la fois qualitative et quantitative des processus cotiers observes pendant la periode d'acquisition des donnees. Les autres donnees, soit la salinite, les courants et les concentrations en pigments chlorophylliens, sont analysees de facon a identifier la variabilite spatio-temporelle des caracteristiques des eaux de surface. L'ensemble des informations permet de produire une carte preliminaire regionale d'indices du potentiel maricole de la partie centrale de la baie des Chaleurs. Selon cet indice (defini entre 0 et 1), le secteur de potentiel aquicole de 0,5 a 0,75 s'etend sur une superficie d'environ 300 kmsp2. La localisation de cette aire potentielle est en accord avec les fortes concentrations en pigments chlrophylliens, presentant des conditions environnementales ideales a une haute productivite biologique. Par la suite la carte preliminaire est modifiee en tenant compte des parametres du niveau 2. Ces parametres sont la geomorphologie littorale, la bathymetrie, les sediments en suspension, les vents, les vagues, le debit d'eau douce, la glace marine, le carbone organique dissous, les aires de peche et les sources de pollution.

    As of December 1, 1998, 32 Europeans LWRs are loaded with MOX fuel. It clearly means that plutonium recycling in MOX fuels is a mature industry, with successful operational experience in fabrication plants in some European countries, especially in France. Indeed, the recycling of plutonium generated in LWRs is one of the objectives of the full Reprocessing-Conditioning-Recycling (RCR) strategy chosen by France in the 70's. The most impressive results of this strategy, is the fact that 31 of the 32 reactors are loaded with MOX fuels supplied by the COGEMA Group from the same efficient fabrication process, the MIMAS process, improved for the MELOX plant to become the A-MIMAS process. In France, 17 reactors are already loaded and 11 additional reactors are technically suited to do so. Indeed, the EDF MOX program plans to use MOX in 28 of its 57 reactors. An EDF 900 MWe reactor core contains 157 assemblies of 264 rods each. 52 fuel assemblies per year are necessary for a 'UO 2 3-batches-MOX 3-batches' core management. In this case, a third of the UO 2 and a third of the MOX assemblies are replaced yearly, that means 36 UO 2 fuel assemblies and 16 MOX fuel assemblies. Some MOX fuelled reactors have now switched from the previously described core management to a so-called 'hybrid core management'. In this case, a quarter of UO 2 assemblies is replaced yearly. The first EDF reactor loaded with MOX fuel was Saint-Laurent B1, in 1987. The in-core experience, based on several hundred assemblies loaded, with reloading on a 1/3 cycle basis, shows that there is no operational difference between UO 2 and MOX fuels, both in terms of performance and safety. MOX fueling of 900 MWe EDF's PWRs, with a limited in-core MOX ratio of 30%, has needed only minor adaptations, such as addition of control rods, modification of the boron concentration in the cooling system and precaution against radiation exposure, easy to set up (optimisation of the fresh MOX fuel handling process, remote

    conducted where every aspect of this large project was scrutinised by an international panel of independent experts. The panel found that the E-ELT project is technically ready to enter the construction phase. The go-ahead for E-ELT construction is planned for 2011 and when operations start early in the next decade, European, Brazilian and Chilean astronomers will have access to this giant telescope. The president of ESO's governing body, the Council, Laurent Vigroux, concludes: "Astronomers in Brazil will benefit from collaborating with European colleagues, and naturally from having observing time at ESO's world-class observatories at La Silla and Paranal, as well as on ALMA, which ESO is constructing with its international partners." Notes [1] After ratification of Brazil's membership, the ESO Member States will be Austria, Belgium, Brazil, the Czech Republic, Denmark, France, Finland, Germany, Italy, the Netherlands, Portugal, Spain, Sweden, Switzerland and the United Kingdom. More information ESO, the European Southern Observatory, is the foremost intergovernmental astronomy organisation in Europe and the world's most productive astronomical observatory. It is supported by 14 countries: Austria, Belgium, the Czech Republic, Denmark, France, Finland, Germany, Italy, the Netherlands, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

    Within the EU project PEGASOS one of three field campaigns took place in the Po Valley during the summer of 2012. Photochemistry, particle formation, and particle properties related to diurnal evolution of the PBL were investigated through both in-situ and airborne measurements on board a Zeppelin NT air ship. In addition, 3-D air quality modeling systems were implemented over the Po valley for the summer 2012 to better characterize the atmospheric conditions, in terms of meteorological parameters and chemical composition. In this work, we present a comparison between atmospheric composition simulations carried out by the modeling system NINFA/AODEM with measurements performed during the PEGASOS field campaign for the period 13 June - 12 July 2012. NINFA (Stortini et al., 2007) is based on the chemical transport model CHIMERE (Bessagnet et al., 2008), driven by COSMO-I7, the meteorological Italian Limited Area Model, (Steppeler et al., 2003). Boundary conditions are provided by Prev'air data (www.prevair.org), and emission data input are based on regional, national and European inventory. Besides, a post-processing tool for aerosol optical properties calculation, called AODEM (Landi T. C. 2013) was implemented. Thus, predictions of Aerosol Optical Depth and aerosol extinction coefficient were also used for model comparison to vertical-resolved observations. For this experiment, NINFA/AODEM has been also evaluated by using measurements of size-segregated aerosol samples, number particles concentration and aerosol optical properties collected on hourly basis at the 3 different sampling sites representative of urban background (Bologna), rural background (San Pietro Capofiume) and remote high altitude station (Monte Cimone 2165 ma.s.l.). ). In addition, we focused on new particles formations events and long range transports from Northern Africa observed during the field campaign.

    In August and September 2010, the U.S. Geological Survey, in cooperation with Natural Resources Canada, Geological Survey of Canada, conducted bathymetric and geophysical surveys in the Beaufort Sea and eastern Arctic Ocean aboard the U.S. Coast Guard Cutter Healy. The principal objective of this mission to the high Arctic was to acquire data in support of a delineation of the outer limits of the U.S. and Canadian Extended Continental Shelf in the Arctic Ocean, in accordance with the provisions of Article 76 of the United Nations Convention on the Law of the Sea. The Healy was accompanied by the Canadian Coast Guard icebreaker Louis S. St-Laurent. The scientific parties on board the two vessels consisted principally of staff from the U.S. Geological Survey (Healy), and the Geological Survey of Canada and the Canadian Hydrographic Service (Louis). The crew also included marine-mammal observers, Native-community observers, ice observers, and biologists conducting research of opportunity in the Arctic Ocean. Despite interruptions necessitated by three medical emergencies, the joint survey proved largely successful. The Healy collected 7,201 trackline-kilometers of swath (multibeam) bathymetry (47,663 square kilometers) and CHIRP subbottom data, with accompanying marine gravity measurements, and expendable bathythermograph data. The Louis acquired 3,673 trackline-kilometers of multichannel seismic (airgun) deep-penetration reflection data along 25 continuous profiles, as well as 34 sonobuoy refraction stations and 9,500 trackline-kilometers of single-beam bathymetry. The coordinated efforts of the two vessels resulted in seismic-reflection-profile data that were of much higher quality and continuity than if the data had been acquired with a single vessel alone. The equipment-failure rate of the seismic equipment aboard the Louis was greatly reduced when the Healy led as the ice breaker. When ice conditions proved too severe to deploy the seismic system, the Louis led

    The Quebec Patient Smart Card Project is a Provincial Government initiative under the responsibility of the Rgie de l'assurance-maladie du Québec (Quebec Health Insurance Board). Development, implementation, and assessment duties were assigned to a team from Université Laval, which in turn joined a group from the Direction de la santé publique du Bas-St-Laurent in Rimouski, where the experiment is taking place. The pilot project seeks to evaluate the use and acceptance of a microprocessor card as a way to improve the exchange of clinical information between card users and various health professionals. The card can be best described as a résumé containing information pertinent to an individual's health history. It is not a complete medical file; rather, it is a summary to be used as a starting point for a discussion between health professionals and patients. The target population is composed of persons 60 years and over, pregnant women, infants under 18 months, and the residents of a small town located in the target area, St-Fabien, regardless of age. The health professionals involved are general practitioners, specialists, pharmacists, nurses, and ambulance personnel. Participation in the project is on a voluntary basis. Each health care provider participating in the project has a personal identification number (PIN) and must use both an access card and a user card to access information. This prevents unauthorized access to a patient's card and allows the staff to sign and date information entered onto the patient card. To test the microprocessor card, we developed software based on a problem-oriented approach integrating diagnosis, investigations, treatments, and referrals. This software is not an expert system that constrains the clinician to a particular decisional algorithm. Instead, the software supports the physician in decision making. The software was developed with a graphical interface (Windows 3.1) to maximize its user friendliness. A version of the

According to the soft-point model of plate breakup developed by Laurent Geoffroy (2005), volcanic passive margins are mantle plume related. They are generated in continental crust positioned above or in the near vicinities of the magma-invaded lithosphere. The large volumes of melted mantle intrude the upper mantle and the crust, erupting onto the surface creating the LIPs. If a mega-continent is impinged by several mantle plumes and later broken apart as a result of their activity, volcanic margins will develop in the vicinities of the plumes (soft points) and magma-poor margins will develop in the connecting areas far from the plumes (hard points). Litosphere becomes so weakened by the thermal anomaly that it breakups much more quickly (volcanic margins) than in the hard areas (magma-poor margins). Transitional margins, with characteristics of both end-members, develop when the soft points approach the hard points. In the South Atlantic Ocean, the Pelotas Basin is a typical volcanic passive margin while the Santos, Campos and Espírito Santo Basins are examples of magma-poor passive margins. The Sergipe-Alagoas, Potiguar and Ceará Basins are examples of margins displaying characteristics of both sedimentary and volcanic margins.

  16. Etude de l'impact de la valorisation energetique de pneus hors d'usage, dans une cimenterie, sur les emissions gazeuses par modelisation de la dispersion atmospherique

    Science.gov (United States)

    Bredin, Nathalie

    La génération incéssante de déchets nécessite le développement de nouvelles technologies, telle que la valorisation énergétique, pour en disposer. Une filière appropriée pour valoriser énergétiquement les déchets est le procédé cimentier. L'industrie du ciment est une des grandes consommatrices d'énergie. La température nécessaire à la préparation du ciment se situe aux environs de 1450°C pour faire réagir la matière première (cru) qui est sous forme poudreuse et constituée principalement de roches calcaires, argileuses, schisteuses,... Les gaz de combustion ont un long temps de résidence dans les fours. De plus, le mode de fonctionnement des fours est responsable d'un effet de lessivage des gaz acides par le cru alcalin. Ces propriétés font du procédé cimentier un bon candidat pour la valorisation énergétique des déchets. Les déchets interessants pour les cimenteries sont, entre autres, les huiles usées, les solvants usés et les pneus usés qui ont un pouvoir calorifique équivalent à celui du charbon. Les rejets à l'atmosphère des cimenteries sont principalement des émissions gazeuses. Ainsi, l'impact de la valorisation de pneus usés sur les émissions gazeuses de la cimenterie Saint-Laurent de Joliette a été étudié, à l'aide de l'outil qu'est la modélisation de la dispersion atmosphérique. Le modèle utilisé ISC-ST2, Industrial Source Complex-Short Term, est de type gaussien. L'analyse des concentrations maximales horaires et moyennes sur différentes périodes de temps (1 heure, 8 heures, ..., 1 an) des émissions gazeuses dans l'air ambiant montre que celles-ci sont en deçà des normes émises par le gouvernement québécois et par la Communauté Urbaine de Montréal. L'étude de la distribution géographique des polluants, d'après les concentrations annuelles, dans un rayon de 5 km autour de la cimenterie montre que le fait d'utiliser des pneus comme combustible de substitution n'a qu'un faible impact sur la

  18. Fuchsia : A tool for reducing differential equations for Feynman master integrals to epsilon form

    2017-10-01

    We present Fuchsia - an implementation of the Lee algorithm, which for a given system of ordinary differential equations with rational coefficients ∂x J(x , ɛ) = A(x , ɛ) J(x , ɛ) finds a basis transformation T(x , ɛ) , i.e., J(x , ɛ) = T(x , ɛ) J‧(x , ɛ) , such that the system turns into the epsilon form : ∂xJ‧(x , ɛ) = ɛ S(x) J‧(x , ɛ) , where S(x) is a Fuchsian matrix. A system of this form can be trivially solved in terms of polylogarithms as a Laurent series in the dimensional regulator ɛ. That makes the construction of the transformation T(x , ɛ) crucial for obtaining solutions of the initial system. In principle, Fuchsia can deal with any regular systems, however its primary task is to reduce differential equations for Feynman master integrals. It ensures that solutions contain only regular singularities due to the properties of Feynman integrals. Program Files doi:http://dx.doi.org/10.17632/zj6zn9vfkh.1 Licensing provisions: MIT Programming language:Python 2.7 Nature of problem: Feynman master integrals may be calculated from solutions of a linear system of differential equations with rational coefficients. Such a system can be easily solved as an ɛ-series when its epsilon form is known. Hence, a tool which is able to find the epsilon form transformations can be used to evaluate Feynman master integrals. Solution method: The solution method is based on the Lee algorithm (Lee, 2015) which consists of three main steps: fuchsification, normalization, and factorization. During the fuchsification step a given system of differential equations is transformed into the Fuchsian form with the help of the Moser method (Moser, 1959). Next, during the normalization step the system is transformed to the form where eigenvalues of all residues are proportional to the dimensional regulator ɛ. Finally, the system is factorized to the epsilon form by finding an unknown transformation which satisfies a system of linear equations. Additional comments

Identifying comorbid conditions and physiologic changes due to aging allows oncologists to better assess the risk/benefit ratio and to adjust the treatment accordingly. Conducting a Comprehensive Geriatric Assessment (CGA is one approach developed for this purpose. We reviewed the evidence on the usefulness of CGA for assessing health problems and predicting cancer treatment outcomes, functional decline, morbidity, and mortality in older patients with solid malignancies. Methods: We searched Medline for articles published in English between January 1, 2000 and April 14, 2014, and reporting prospective observational or interventional studies of CGA feasibility or effectiveness in patients aged ≥65 years with solid malignancies. We identified studies with at least 100 patients, a multivariate analysis, and assessments of at least five of the following CGA domains: nutrition, cognition, mood, functional status

Calcium aluminate and aluminosilicate glasses are attractive materials for a wide range of technical applications due to their highly refractory nature, their excellent optical and mechanical properties. The CaO-Al2O3-SiO2 system (CAS) is remarkable since glasses with very few SiO2 content can be synthesized, contrary to alkali or Mg aluminosilicate glasses. We have synthesized more than 40 different glasses in the CAS system using quenching method and 15 glasses using laser heating. These glasses were studied using a Raman spectrometer T64000 from Jobin-Yvon-Dilor company, X-ray absorption spectroscopy at Si, Al, Ca K edges the SA32 and D44 beamlines at LURE and NMR-700MHz. Cormier et al (2000) have shown using X-ray and neutron diffraction that aluminium is in 4-fold coordination in this ternary system. In this present study, we present Raman and XANES obtained at room temperature for these glasses. On the join SiO2-CaAl2O4 glass, we observed a decrease in Raman frequency with increasing CaAl2O4 content for all the bands. In particular, we observed a big decrease in frequency for the T4 band near 1150 cm-1 assigned to T-O0 in T4 units. This decrease suggests that aluminium substitutes principally for Si4+ in the fully polymerized structural units (TO2) according with Neuville and Mysen (1996). On the join SiO2-Ca3Al2O7 (R=CaO/AL2O3=3), we observed a decrease for all bands with

    Full Text Available Malgré l’intérêt porté aux œuvres d’art religieuses du XIXe siècle depuis une trentaine d’années, beaucoup de vitraux religieux du XIXe siècle ont déjà disparu à Paris ; il s’avère donc urgent de les inventorier. L’objet de l’article qui suit est la présentation des édifices catholiques parisiens de style néogothique et de leurs verrières. Ce corpus comprend 5 églises paroissiales, 19 chapelles de congrégations ou anciennes chapelles devenues paroisses, et deux bâtiments annexes. Sur 526 verrières étudiées, 286 sont ornées de figures ou de scènes dont 37 entrent dans la catégorie vitrail-tableau ; les 240 autres verrières sont ornementales. 22 ateliers sont à l’origine de ces verrières, parmi les plus importants tels Didron, Lusson, Champigneulle, Hirsch, Gsell, etc. L’on sait que Paris a joué un rôle déterminant dans la renaissance du vitrail durant le premier tiers du XIXe siècle, grâce à la perspicacité de certains hommes de pouvoir comme le comte de Chabrol qui fut à l’origine de la « résurrection » du métier de peintre verrier avec la création du premier atelier de la Foire Saint-Laurent en 1825, grâce également à la confrontation des archéologues avec les premiers grands chantiers de restauration et le rôle décisif des architectes diocésains. L’iconographie de ces verrières reflète l’évolution du contexte religieux, de la liberté concordataire à l’explosion congrégationniste, du retour de l’autorité romaine au triomphe de l’ultramontanisme, du mouvement anticongrégationniste à la loi de Séparation de 1905. Le vitrail néogothique épouse plutôt une iconographie de tendance gallicane, teintée d’un certain « romantisme » ; mais à partir de 1850, il s’ouvre à de nouvelles images et devient ce que l’on pourrait appeler un « moyen de propagande ». Le vitrail néogothique marque le retour à la couleur ; l’imitation des Anciens exige

Of Europe's 218 commercial reactors in operation, the majority, 151, are located i the Western part. The biggest producers are France, United Kingdom and Germany, with 58, 35 and 20 reactors respectively. Until now mostly research- and pilot reactors have been shut-down. There are yet few experiences from decommissioning of large-scale commercial reactors. The following commercial reactors are undergoing decommissioning. (There are also a great amount of nuclear facilities of other types being decommissioned.) The three gas-cooled twin reactor plants of Berkeley, Trawsfynydd and Hunterston in UK. In Germany Gundremmingen, Lingen, Kahl and Wuergassen are being decommissioned. All of them are located in the Western part of the country. The biggest project is however the dismantling of the gigantic Greifswald facility situated on the coast of the Baltic see in former Eastern Germany. The plant has eight Russian built reactors of VVER-type. Like the rest of the former GDR-plants Greifswald was shutdown after the reunification in 1990. The strategy chosen is immediate dismantling. France is decommissioning seven reactors (Chooz A1, Chinon A1, A2, A3, St Laurent A1, A2 and Bugey 1.) The oldest, Chinon A1, closed down in 1973 and the youngest, Bugey 1, in 1994. Italy closed down all NPPs (altogether four) in 1987 after a referendum. The first reactor of the Netherlands was shutdown in 1997 mainly for economical reasons. The development of a free European electricity market will make it less profitable to run certain facilities. Vandelos 1 in Spain is undergoing decommissioning after a fire in the turbines in 1989. IAEA, OECD/NEA and EU are co-operating in the field of decommissioning. Much work is spent on harmonizing rules and preparing international guidelines. The international agencies

    unpolluted soils were mostly gypseous and/or calcareous especially in the middle parts. Considering the surface and subsurface diagnostic horizons and the aridic-thermic soil moisture and temperature regimes, the studied soils were classified as Gypsids, Calcids or Cambids (Soil Survey Staff, 2014. However, due to the added oil waste compounds and presence of impermeable geomembrane in some of the polluted pedons, they were classified as Technosols in the WRB system (FAO, 2014. Noticeable effects of Pollutants in the soil were decreasing pH and increasing OM and EC. The surface horizons of the unpolluted soils contained less than 2 percent organic matter which regularly decreased by depth. However, In some horizons of the polluted soils, soil organic matter exceeded 12 percent. pH decreased by increasing organic matter (oil waste compounds possibly due to H+ dissociation from the oil compounds (Laurent et al., 2012. Electrical conductivity throughout the polluted soil horizons showed more limited variability than the unpolluted ones, probably due to their higher capability in water and liquid dynamics. Liquid limit and plasticity limit in polluted soils are higher than unpolluted soils . Plasticity index in polluted soils decreased with increasing the amount of pollutants. The results of mineralogical studies corroborated that dominant clay mineral in this soils is Smectite. Smectites have high swelling and shrinking capacity.So, the pollutants can intercalate between soil mineral layers and then increase d-spacing of clay minerals. The micromorphology of the polluted soils showed that low dielectric constant of petroleum caused flocculation and formation granular aggregates in soil. Studied soils are inactive in terms of activity of clay. Conclusion: As observed in the studied soils, their physico-chemical properties such as pH and electrical conductivity (EC of saturated paste extract, organic matter content, mineralogical and micro-morphological properties were severely

    Full Text Available Cet article analyse les interactions socioculturelles d’acteurs multiples ayant des intérêts divergents en regard de la reconnaissance d’un espace naturel à titre d’aire protégée, plus particulièrement le Parc marin du Saguenay–Saint-Laurent (PMSSL, situé au Québec à l’embouchure de la rivière Saguenay. Compris dans le sens d’espace socialisé et investi de valeurs parfois contradictoires, ce territoire constitue le cas empirique sur lequel repose l’analyse des logiques d’acteurs. La perspective ici mise de l’avant repose à la fois sur une décision de l’État de créer et de mettre en valeur une aire marine ainsi que sur la participation active des collectivités territoriales dans la gestion du patrimoine environnemental et culturel lié à leur identité propre. Si la participation des communautés locales apparaît comme un élément essentiel et démocratique dans la reconnaissance d’un espace naturel protégé, il apparaît tout aussi capital de bien saisir la logique qui sous-tend les actions de l’État et du milieu. Les résultats empiriques montrent deux logiques d’action distinctes à l’œuvre, une logique classique de planification et implantation stratégique de l’état réservant une espace de participation programmée pour la communauté et une logique stratégique communautaire à caractère émergent, de portée moins englobante mais adaptable aux nouvelles réalités et contraintes gouvernementales. Les résultats peuvent être représentés sous forme d’un processus de gouvernance à l’œuvre, un caractérisé par une participation de base, mais un qui suggère qu’un processus plus hautement démocratique nécessiterait un plus haut degré de vigilance dans la perspective communautaire, suffisante pour produire une meilleure symétrie de pouvoir démocratique entre l’État.This paper analyzes the socio-cultural dynamic between multiple stakeholders with divergent interests

    critical thinking as early as the their first semester was something revolutionary and very attractive. This teaching strategy was so well accepted that was common to find either students who had already approved the course of Biochemistry or students attending advanced semesters returning to attend the class and to see the beloved teacher once again! In class it was possible to both discuss biochemistry and learn history! To have the classroom invaded by "actors" playing the judgment and beheading of Antoine-Laurent Lavoisier over 100 years after his death while discussing his experiments caused a whirlwind of emotions in the students. This was important to sensitize them to the challenges experienced by renowned scientists who paid with their lives to defend their ideas. Thus, students became protagonists of story and the biochemistry classes more interesting and challenging. This challenge was shared by the "actors", who actually were students of the Biological Chemistry program sharing the classroom with the great master. For these graduate students, it was an experience where they raised awareness of the importance of dedication to the teaching of Sciences.Prof. de Meis’ speech where he stated no one owns the truth or all knowledge was another point closing the relationship with the undergraduate students. In the modern world it is nearly impossible to keep yourself up to date, so we ended up specializing in something. De Meis used to cause some perplexity among the students by showing a picture with all copies of a single reputable scientific journal in the biochemistry field published over a year. Surprisingly, this stack of magazines was 1.5 meters tall! Could you imagine that all recent knowledge in biochemistry is compiled in few pages of a textbook? de Meis, then, revealed that we do not know everything, but we do need to learn how to interpret new facts, a new experiment, a new concept, a new technique, a new discovery. We need to develop critical thinking to

It is based on the proportionality between the distance of a galaxy and its recession velocity (the Hubble law). The higher the velocity, the more its emission will be shifted towards longer wavelengths and the redder is the colour. Recent investigations of galaxies seen in the Hubble Deep Field have shown that the redshifts (and thus distances) found by this method are quite accurate in most cases.

    award was Steven A. Sabbagh et al for the paper entitled 'Resistive wall stabilized operation in rotating high beta NSTX plasmas' (Nucl. Fusion 46 635-644). Reviews Last year I announced a revival of Nuclear Fusion Reviews, following a decision by the Board of Editors. 'A review of zonal flow experiments', by Akihide Fujisawa was the first fruit of this. In 2010, we are expecting to publish further review articles, the first of which is entitled 'Gyrokinetic simulations of turbulent transport' by Xavier Garbet, Yasuhiro Idomura, Laurent Villard and Tomo-Hiko Watanabe. Letters At the 2009 Board of Editors Meeting in Atlanta, the current letters procedure was summarized and it was noted that the peer review time for Letters is quite variable. Some are accepted within a month of submission, others take longer. Since the purpose of Letters is to provide a route for rapid communication, this is quite an important matter. It was agreed that the Board of Editors would play a more active role in the Letter approval process. If a reviewer asks for a second revision the Editor or a Board of Editors member will be queried as to whether the submission should still be treated as a Letter rather than a regular Paper. The Board of Editors The following Board of Editors members reached the end of their term in 2009: Amanda Hubbard, Yaroslav Kolesnichenko, Kunioki Mima, Boris Sharkov and Michael Ulrickson.
