  6. Literary positivism? Scientific theories and methods in the work of Sainte-Beuve (1804-1869 and Wilhelm Scherer (1841-1886

    Full Text Available Literary positivism? Scientific theories and methods in the work of sainte-beuve (1804-1869 and wilhelm scherer (1841-1886 This paper compares the research and critical work of Charles-Augustin Sainte-Beuve and Wilhelm Scherer, two of the most important representatives of ‘literary positivism’ in France and the Germanophone countries in the nineteenth century. It argues that although Sainte- Beuve and Scherer shared a research interest in deterministic biography, their work is too rich and too varied to lump it together under the commonly assigned label of ‘positivism’. Sainte- Beuve’s descriptive comparative literary criticism was meant to establish a database of human character types and thereby lay the groundwork for a future science of morals. Scherer, on the other hand, was mainly interested elaborating inductive hypotheses on the causal determination of individual life and literary history by various social and physiological factors. The paper elicits the different scientific sources of knowledge that Sainte-Beuve and Scherer drew upon. While Sainte-Beuve’s classification of character types is strongly in - formed by his reception of the comparative natural sciences, especially late eighteenth/early nineteenth century botany and zoology, Scherer’s research is in many respects conceived as a humanistic equivalent to the empirical inductive research model of German physical reductionism. Finally, the paper elucidates the specific political contexts to which Sainte-Beuve and Scherer reacted in their research.

    Sum rules provide useful insights into transition strength functions and are often expressed as expectation values of an operator. I will show that non-energy-weighted transition sum rules have strong secular dependences on the energy of the initial state. Such non-trivial systematics have consequences: the simplification suggested by the generalized Brink-Axel hypothesis, for example, does not hold for most cases, though it weakly holds for electric dipole transitions. Furthermore, I show the systematics can be understood through spectral distribution theory, calculated via traces of operators and of products of operators; seen through this lens, violation of the generalized Brink-Axel hypothesis is unsurprising.

  1. Modification of the Brink-Axel Hypothesis for High Temperature Nuclear Weak Interactions

    Misch, G Wendell; Brown, B Alex

    2014-01-01

    We present shell model calculations of electron capture strength distributions in A=28 nuclei and computations of the corresponding capture rates in supernova core conditions. We find that in these nuclei the Brink-Axel hypothesis for the distribution of Gamow-Teller strength fails at low and moderate initial excitation energy, but may be a valid tool at high excitation. The redistribution of GT strength at high initial excitation may affect capture rates during collapse. If these trends which we have found in lighter nuclei also apply for the heavier nuclei which provide the principal channels for neutronization during stellar collapse, then there could be two implications for supernova core electron capture physics. First, a modified Brink-Axel hypothesis could be a valid approximation for use in collapse codes. Second, the electron capture strength may be moved down significantly in transition energy, which would likely have the effect of increasing the overall electron capture rate during stellar collapse...

    The gamma strength function (GSF) and level density (LD) of 1- states in 96Mo have been extracted from a high-resolution study of the (p,p') reaction at 295 MeV and extreme forward angles. The GSF agrees with results of compound nucleus gamma decay experiments in the energy region of the Pygmy Dipole Resonance (PDR), validating the generalized Brink-Axel hypothesis commonly assumed in astrophysical reaction network calculations. The consistency of the LD deduced from the present data with those of the gamma decay experiments provides independent confirmation of the methods used to separate GSF and LD in Oslo-type experiments.

    2012-12-01

    Full Text Available In this article we intend to discuss central aspects of the concept reification conceived by Georg Lukács in his book “History and Class Consciousness”. Our aim, however, is to show the interpretation that Axel Honneth proposes as an actualization of that concept through an attempt to overcome the subject-object epistemological tradition in favor of an intersubjectivity theory. We intent to show how Honneth's reading of reification tries to give it a contemporary formulation taking his own theory of recognition as basis. Postulating social theory and ontological problems, this understanding about the reification has implications to his own intellectual trajectory, as well as to the thinking of critical theory in the context of contemporary society.

    To search for neutrinoless double beta decay, we have started developing a high pressure xenon gas time projection chamber as the AXEL (A Xenon ElectroLuminescence detector) project since 2014. We proposed a new scheme to measure energy deposit using electroluminescence lights to achieve high energy resolution, large mass and strong background rejection power. Important performances of compositions of our new readout scheme are shown: electric field simulation, VUV sensitivity of MPPC in high pressure gaseous xenon, response of MPPC for large amount of photons. To demonstrate as a whole system, we constructed a small prototype detector using 64 MPPCs filled with 4 bar xenon gas. Result of measurement with a 57Co gamma-ray source are shown.

A Escola de Frankfurt, desde 1930, foi dirigida por Max Horkheimer, e reunia pensadores como Theodor W. Adorno, Erich Fromm, Herbert Marcuse, e, contou também como membro do "círculo de fora" do Instituto, Walter Benjamin. Estes intelectuais formularam, como sabemos, o que conhecemos como "Teoria Crítica". Nos anos sessenta, temos a "segunda geração", marcado pela obra de Jürgen Habermas. Aquele que foi seu assistente entre 1984 e 1990, Axel Honneth, veio a ser o Diretor do Instituto frankfurtiano desde 2001. Com ele inaugura-se a "terceira geração" da Escola, cuja proposta consiste em relançar a "Teoria Crítica", sobretudo a partir do livro Kampf um Anerkennung. Zur moralischen Grammatik sozialer Konflikte, de 1992 (publicado no Brasil como Luta por reconhecimento - A Gramática Moral dos Conflitos Sociais. Trad. Luiz Repa. São Paulo: Ed. 34, 2003, tendo como ponto de partida a Fenomenologia do Espírito de Hegel. Honneth centra sua reflexão na "teoria do reconhecimento" e, através dela, são apresentados os limites da obra das gerações de frankfurtianos anteriores.  A falta de reconhecimento passa a ser vista como base dos conflitos interpessoais, sociais e políticos na atualidade. Mais recentemente, Honneth publicou Das Recht der Freiheit (Berlin, Suhrkamp, 2011 - O direito à liberdade e Die Idee des Sozialismus (Berlin, Suhrkamp, 2015 - A ideia do socialismo, sustentando que o socialismo está vivo como ideia, e tem como cerne a liberdade social.

  11. Humour and the locus of control in The Gruffalo (Julia Donaldson & Axel Scheffler

    2007-07-01

    Full Text Available The purpose of this article is firstly to distinguish between the notions “external locus of control” and “internal locus of control”, secondly to indicate ways in which the locus of control in humour in “The Gruffalo” by Julia Donaldson and Axel Scheffler can be identified and thirdly to indicate possible ways in which emphasis on the internal locus of control in the young reader can assist him/her in the development of a general mental/- psychological well-being. Different kinds of literary humour contribute to the ways in which young listeners/readers can identify with stories, poems, dramas and films. The young listener/reader can recognise him/herself in humorous situations, in the humorous use of imagery, wordplay and illustrations/visuals. He/she can also identify with or distance him-/herself from or reject the characters, the values represented and the author who created the text. When in interaction with the works of authors who use negative as well as positive kinds of humour to point out the dos and don’ts, the rights and the wrongs in life, the horizon of a young listener’s/reader’s experience can be expanded. Such a reading would contribute to the development of the young reader’s cognitive, emotional, social and moral values as it links up with an unconscious or conscious decision about the locus of control in his/her life.

  12. The concept of social domination in axel Honneth’s critical theory

    2015-01-01

    Full Text Available This paper attempts to reconstruct the concept of social domination articulated in the early works of Axel Honneth, a key figure of the ‘third generation’ of critical theory. The author argues that one of the key ambitions of the early Honneth, expressed through his critique of Jurgen Habermas, was to theorize the process of societal reproduction in contemporary capitalism in ‘action-theoretic’ terms, i.e. as determined by the inter-group dynamics of social conflict and domination, as opposed to Habermas’ systems-theoretic approach. The author analyzes Honneth’s criticism of Habermas developed in ‘The Critique of Power’, and focuses more narrowly on Honneth’s conceptualization of social domination outlined in the early article ‘Moral Conscioussness and Class Domination’. The analysis grounds the author’s subsequent reconstruction of the early Honneth’s conception of social domination as a two-dimensional phenomenon that encompasses an ‘intentional’ and a ‘structural’ dimension. Turning towards Honneth’s mature perspective, the author argues that a critique of social domination no longer occupies a central place in Honneth’s influential theory of recognition. Finally, the author considers Honneth’s only recent attempt at theorizing domination presented in the article ‘Recognition as Ideology’, and argues that Honneth has so far missed the opportunity to integrate the early social-theoretical perspective on domination into his mature theoretical system.

    Jacinta Gorriti

    2015-06-01

    Full Text Available This article presents a critical reading of Axel Honneth’s work “Recognition as ideology” (2006, built upon Judith Butler’s theory of subjection. It attempts to show that because of not considering here enough the dimension of power, the German thinker does not confront successfully the stances that question recognition’s critical potential. This work suggests that such an absence is linked to Honneth’s definition of recognition as being the opposite of practices of domination or subordination. However, Honneth affirms that these skeptical stances are based on the idea that every recognitional praxis reproduces in some way the dominating social order. This article offers then, a critical look upon this idea, warning that an analysis about the way power works on daily recognition practices does not necessarily entail a resignation of the critical function of recognition. More likely, as the Butlerian (and Foucauldian notion of critique suggests, only by framing recognition in the normative horizon that defines it, it can become the basis of social inquiry.

    Full Text Available O presente estudo teórico tem como objetivo relacionar uma discussão sobre o trabalho em equipe interdisciplinar nos serviços públicos de saúde com os principais conceitos do filósofo contemporâneo Axel Honneth, dentre eles aquele que denominou Luta por Reconhecimento. Para tanto, partimos da revisão da noção de sujeito na teoria honnethiana, sobretudo a partir do diálogo que faz com a psicanálise de Donald Winnicott. Destacamos que se trata de um sujeito eminentemente social, cuja constituição depende do reconhecimento do outro em relação a sua alteridade e da legitimação do seu pertencimento a um grupo social. Mostramos que esse reconhecimento se dá através de um processo de luta, essencial para o desenvolvimento da capacidade de amar e se relacionar com o outro. Em seguida, defendemos que o trabalho em equipes interdisciplinares pode ser um espaço para o reconhecimento dos profissionais, tal como discutido por Honneth. Consequentemente, as equipes podem facilitar o desenvolvimento de trabalhos criativos e inovações na organização da assistência oferecida aos pacientes.This theoretical study aims to correlate the discussion about interdisciplinary teamwork in public health institutions with the key concepts of contemporary philosopher Axel Honneth with regards to what he called the Struggle for Recognition. We start by revising the notion of subject in Honneth's theory, especially based on his dialogue with Donald Winnicott's psychoanalysis. We highlight that this subject is eminently social; its constitution depends on the recognition of others regarding its otherness and the legitimacy of its belonging to a social group. Next, we show that this recognition occurs through a process of struggle, which is essential for developing the capacity to love and to relate to others. We then argue that the work in interdisciplinary teams can be configured as a potent space for the recognition of professionals, as discussed by

    2015-01-01

    Full Text Available Esse artigo tem por objetivo analisar as contribuições de Axel Honneth para o atual debate das teorias da justiça, entre as quais a principal é a busca de princípios normativos encrustados na realidade social. Em sua obra O direito da liberdade, o autor indica a liberdade como o grande valor moderno. O medium da justiça seria uma liberdade de tipo social a qual estaria expressa nas instituições vinculadas às relações pessoais, ao mercado e ao universo político. Considerando a lacuna entre os princípios normativos de justiça indicados pelo autor e a realidade social este artigo propõe colocar em discussão as potencialidades e limites da própria reconstrução normativa como instrumento de análise do social, pautando especificamente o mercado de trabalho, a fim de colaborar à discussão das possibilidades de articular a norma compartilhada e a emergência de valores em vias de institucionalização

Para abordar satisfactoriamente este problema consideramos necesario, previamente, reseñar cuáles son las principales afirmaciones del libro y cuál es su enfoque teórico general (1. En el libro de Honneth el tema de la dominación se asocia fuertemente a dos nociones: la de “patologías sociales y de la razón” y la de “anomia”, motivo por el cual centraremos fuertemente la atención en estas cuestiones y llevaremos adelante -y esto vale para todo el artículo- lo que metodológicamente se denomina una reconstrucción conceptual-sistemática (2. Nuestra tesis de lectura es que en el Derecho de la Libertad se echa en falta una concepción “robusta” de dominación que el autor promete en otros libros suyos –tal y como lo advertimos en nuestra investigación doctoral, aún en curso–, pero que finalmente no elabora.

En tal sentido las organizaciones mapuches y sus líderes, cuestionan el orden social prevaleciente en Chile y plantean una resistencia práctica, en la convicción moral de que sufren; devaluación cultural, exclusión social, y marginación política, que se traduce en la falta de justicia y negación de reconocimiento a su diferencia cultural. Estas injusticias culturales, están en los patrones sociales de representación, interpretación y comunicación de la sociedad chilena.

  4. Two attempts at grounding social critique in „ordinary“ actors’ perspectives: The critical theories of Nancy Fraser and Axel Honneth

    Directory of Open Access Journals (Sweden)

    Ivković Marjan

    2014-01-01

    Full Text Available This paper analyzes two contemporary, „third-generation“ perspectives within critical theory - Nancy Fraser’s and Axel Honneth’s - with the aim of examining the degree to which the two authors succeed in grounding the normative criteria of social critique in the perspectives of ’ordinary’ social actors, as opposed to speculative social theory. To that end, the author focuses on the influential debate between Fraser and Honneth Redistribution or Recognition? which concerns the appropriate normative foundations of a „post-metaphysical“ critical theory, and attempts to reconstruct the fundamental 29 disagreements between Fraser and Honneth over the meaning and tasks of critical theory. The author concludes that both critical theorists ultimately secure the normative foundations of critique through substantive theorizations of the social, which frame the two authors’ „reconstructions“ of the normativity of everyday social action, but argues that post-metaphysical critical theory does not have to abandon comprehensive social theory in order to be epistmologically „non-authoritarian“.

    Ambers are well known and abundant in terrestrial sediments all over the world; however, due largely to the absence of definite morphological characteristics, the precise botanical origin of most amber samples, are at best, often a matter of speculation. This has severely restricted the usefulness of amber in paleobotanical and paleoecological interpretations. The molecular composition and structural characteristics of fossil resins however, may preserve evidence of their botanical origin, which could be of great value in both geochemical, paleobotanical, and paleoenvironmental studies. The remains of a number of exceptionally well-preserved Taxodiaceae-dominated swamp-forest communities have been identified in the sediments of the middle Eocene (45 million years old) Buchanan Lake Formation of Axel Heiberg Island, Canadian Arctic Archipelago. The amber collected from these ancient in situ forests provides a unique opportunity to characterize these resins chemically and taxonomically. Resinite associated with Metasequoia, Pinus and Pseudolarix has been characterized using Pyrolysis-Gas Chromatography-Mass Spectrometry. This method provides a direct analysis of the molecular structure and composition of the resin. In several cases, both bled resin and cone-resin samples have been characterized. The results of these analyses are presented and discussed. The implications of these results for the botanical origins of other ambers represented in the fossil record (including succinite) will also be discussed.

    2015-06-01

    Full Text Available En el presente trabajo abordo la interpretación que Axel Honneth realiza, en su libro Crítica del poder, de la propuesta de Michel Foucault. Honneth señala, a modo de crítica, la existencia de una contradicción entre lo que denomina la teoría del poder de Foucault y sus estudios históricos –en particular, los reunidos en Vigilar y Castigar–. Uno de mis objetivos es explicar esta contradicción y, a partir de ella, proponer una lectura alternativa. En contraposición a Honneth, para quien las instituciones disciplinarias que analiza Foucault terminarían desplazando la acción y la lucha social, intento mostrar –y este es el aporte que busco realizar en el trabajo a partir de una reconstrucción conceptual– que las disciplinas y por añadidura las instituciones disciplinarias deben considerarse tácticas que nunca alcanzan del todo su objetivo. Son tácticas que no logran bloquear, de manera definitiva, las expresiones de resistencia y conflictividad. Esta lectura alternativa que aquí propongo permitiría, en principio, ensayar al menos dos puntos de contacto entre Foucault y la teoría crítica que aún no han sido elucidados.

Na primeira parte do artigo é apresentado o conjunto da obra do autor, buscando evidenciar sua evolução interna e os diálogos que Honneth estabelece com seus antecessores. Na segunda parte, discute-se a pertinência, abrangência ou adaptabilidade da Teoria do Reconhecimento a partir de dois pontos principais apontados pelas diversas interpretações da obra do autor: 1 a concepção individualista da autonomia e as suas implicações sobre o entendimento do papel da ação coletiva na luta pelo reconhecimento; 2 as dificuldades de operacionalização teórico-metodológica do seu sistema conceitual em estudos empíricos, e ainda associadas aos parâmetros cívicos europeus, ou mesmo alemães, sobre os quais o autor constrói sua noção de normatividade. Como será desenvolvido, esses temas se encontram articulados entre si e explorados pelos diferentes artigos que compõem o presente dossiê.

    Full Text Available http://dx.doi.org/10.5007/1677-2954.2010v9n2p231O conceito de reificação, originalmente formulado por Karl Marx e desenvolvido por Georg Lukács, foi incorporado como uma das categorias centrais da teoria crítica em sua tarefa de diagnosticar patologias sociais. Contudo, para a compreensão atual da utilização do conceito, tornou-se necessário libertar seu referencial originário meramente econômico. É isso o que pretende Axel Honneth ao reatualizar o conceito de reificação e seu potencial crítico-normativo a partir da teoria do reconhecimento. Além de retomar os principais aspectos do conceito de reificação segundo a análise do “fetichismo da mercadoria”, o artigo se concentra em apresentar a interpretação de Honneth para os processos sociais reificantes – nas relações dos sujeitos com o mundo circundante, nas relações sociais entre os sujeitos e nos efeitos patológicos da autoreificação sobre a autorealização ética – e para a produção inovadora do diagnóstico das patologias sociais decorrentes da reificação como “esquecimento do reconhecimento”.

    2015-01-01

    Full Text Available O presente artigo explora os principais conceitos que compõe a teoria do reconhecimento de Axel Honneth, a fim de compreender os propósitos imbricados na idéia de luta por reconhecimento e suas contribuições à nova concepção de identidade surgida a partir da modernidade. No padrão pós-convencional, apresentado por Honneth, o indivíduo é reconhecido em sua individualidade. A identidade subjetiva é constituída de forma intersubjetiva e não mais determinada pelo grupo social. O reconhecimento recíproco é condição para a formação prática da identidade, permitindo ao sujeito participar efetivamente na esfera pública. Contudo, por possuir uma estrutura fundamentalmente intersubjetiva, a identidade individual e coletiva é afetada negativamente pelas diferentes situações de desrespeito presente nos processos de interação social. A negação do reconhecimento de modo injustificado, por meio da violação de expectativas normativas de comportamento, da origem a reações emocionais negativas. Por este motivo, as experiências de desrespeito integram a base motivacional da luta por reconhecimento, dando origem ao conflito social. O tema do conflito em Honneth está vinculado aos processos de formação da identidade prática do sujeito e aos progressos na vida social. O conflito social, traduzido na forma de luta por reconhecimento, caracteriza-se como uma expressão altamente positiva, por contribuir significativamente com a autorrealização individual e coletiva.

    Full Text Available Human beings’ relation with time and space has very ancientoffsets. It would be reasonable to seek the first data of these offsets innationalization processes as human beings realized their existencethrough social consensus. This social consensus has certainphenomena which mainly appear in cultural forms. The first data andassigning meanings during nations’ presenting their social existence aremainly found in epics. Therefore, it would be reasonable to focus onepics with a view that they are the codes of nations’ social memories. Itis a known fact that, beginning from their first ancestors, human beingshave always acted in accordance with some main purposes and themes.Therefore the importance of epics is paramount in terms of thearchetypes they accommodate. It is known that these archetypes notonly provide a means to read the past, but also shed light on ourpresent. This provides a remarkable opportunity to reach the roots ofthe cultural phenomena of nations and societies. When we look at theTurkish epics, we are welcomed by Oghuz Khagan Saga, which can becounted as an important leap forward in terms of Turks’ nationalizationprocess. There are different methods to understand and explain orassign meanings to epics. One of these methods is Axel Olrik’s “EpicLaws Theory”, one of the methods of Historical-Geographical FinnishSchool. This theory aims at approaching mythological works with auniversal standardization and evaluating these mythological workswithin the frame of certain principles. The aim of the present article isto read Oghuz Khagan Saga, fraught with symbols in terms of Turkishhistory’s mythical offsets, in the light of Axel Olrik’s epic laws and todiscuss the data obtained thereof in the context of the epic and itsnature.

    From July 20 to August 2, 2008, joint activities sponsored by the Canadian Space Agency (CSA - Space Learning) and NASA (Spaceward Bound) were carried out at the McGill Arctic Research Station (MARS) in the Canadian High Arctic. Established in 1960, MARS consists of two sites located on western Axel Heiberg Island along the shore of Expedition Fiord (lower camp), and 8 km inland, at Colour Lake (upper camp). The MARS upper camp is one of the longest-operating seasonal field research facilities in polar regions. The lower camp was established in 2007 through infrastructure support provided by the CSA. The station is located in a mountainous area dominated by ice caps, outlet and valley glaciers, polar desert, arctic tundra, and permafrost, and is internationally recognized for research on cold, perennial springs associated with the presence of evaporite domes. Six educators from the U.S. and Canada participated in field surveys and hands-on demonstrations with the following objectives: (1) join a team of scientists and engineers to explore the topics of Physical Geography, Geoscience, Astrobiology, and Robotics through experiential learning; (2) discover how remote and extreme polar environments on Earth are used by planetary scientists to better understand the evolution of the Moon and Mars, and to potentially train future planetary explorers; (3) bring that experience back to their classrooms, and assist in the development of space curriculum related to science, technology, and engineering projects carried out at planetary analogue sites. In this paper, we present a summary of operational planning and field surveys that led to successful scientific experiments by 16 participants during the Expedition. Research topics explored prior to, and during the arctic mission include Physical Geography, Geomorphology, Geology, Seismology, Earth Observation, Astrobiology, and Terrain Characterization with implications for future human and robotic exploration missions to the

    Full Text Available O artigo tem por objetivo precípuo socializar o estudo empreendido na Teoria do Reconhecimento, do sociólogo e filósofo alemão Axel Honneth, em estágio pós-doutoral no Núcleo de Pesquisa "Violência e Cidadania", no Programa de Pós-graduação em Sociologia, da UFRGS, no período 2010-2011. A meta foi articular a pesquisa teórica sobre o "reconhecimento intersubjetivo e social" com uma investigação empírica qualitativa sobre as origens do fenômeno de rualização infanto-juvenil, no meio urbano. A hipótese preconizou o primado do reconhecimento negado a crianças e jovens em situação de vulnerabilidade social, em detrimento de condições econômicas desfavoráveis, como causa da migração para a vida nas ruas e da ocorrência dos múltiplos conflitos sociais deflagrados por essa condição. A pesquisa de campo foi realizada em parceria com duas instituições assistenciais de Porto Alegre, que oferecem o Serviço de Apoio Socioeducativo (SASE, conveniadas com a prefeitura municipal. Os resultados corroboraram a hipótese de que as políticas públicas de distribuição de renda desarticuladas das práticas assistenciais e educativas não contribuem para arrefecer as conflitualidades urbanas. Nesse sentido, o Programa SASE, voltado ao atendimento de crianças e jovens das classes populares que vivenciam diuturnamente a desestruturação familiar, o abandono afetivo, moral, intelectual e o desprezo social, contribui para o fortalecimento das três dimensões do reconhecimento: o amor, o direito e a estima social, reintegrando o público alvo ao núcleo familiar e à sociedade.

    Directory of Open Access Journals (Sweden)

    Manuel Aparicio Payá

    2016-06-01

    Full Text Available Axel Honneth propone, inspirándose en el joven Hegel, una concepción de la justicia basada en la idea de reconocimiento. Dicha concepción parte del previo acercamiento a una serie de fenómenos negativos, los cuales define como fallas en el reconocimiento. Desde la óptica de Honneth los fenómenos negativos constituyen patologías sociales y formas de injusticia, debido a la falta de calidad moral de las relaciones intersubjetivas. Las consecuencias socio-psicológicas en las personas que los sufren son la construcción de una identidad dañada y dificultades en el logro de la autorrealización. El presente artículo pretende realizar, recogiendo el planteamiento de Honneth, un análisis ético-político de los fenómenos de estigmatización, invisibilización y cosificación sufridos por las personas con diversidad funcional, llegando a la conclusión de que tales fenómenos suponen la negación de la dignidad personal, en la que reside el fundamento de la justicia que nos debemos unos a otros.

    2007-01-01

    We discuss the connection between absorption, averages and fluctuations in nuclear reactions. The fluctuations in the entrance channel result in the compound nucleus, Hauser-Feshbach, cross section, the fluctuations in the intermediate channels, result in modifications of multistep reaction cross sections, while the fluctuations in the final channel result in hybrid cross sections that can be used to describe incomplete fusion reactions. We discuss the latter in details and comment on the validity of the assumptions used in the develpoment of the Surrogate method. We also discuss the theory of multistep reactions with regards to intermediate state fluctuations and the energy dependence and non-locality of the intermediate channels optical potentials.

    2014-07-01

    The gamma strength function of {sup 96}Mo, derived from a variety of experiments, shows quite severe disagreement, in particular near the neutron threshold. A new experimental method is discussed, viz. relativistic proton scattering under extreme forward angles at RCNP Osaka, Japan, which allows a consistent analysis of data below and above the particle threshold. Here, intermediate-energy proton beams are used in combination with a high energy resolution of the order Δ E/E ∼ 8 . 10{sup -5}. E1 and M1 cross sections can be determined by a multipole decomposition of angular distributions utilizing DWBA calculations. The additional measurement of polarization transfer observables provides an independent check of the method. Results for the gamma strength function of {sup 96}Mo derived from the E1 cross sections are presented and compared to findings with other experimental techniques.

The authors devote themselves to social and political fields of study equally as well as to historical questions related to media and consumerism or body and gender. They focus their interest on the time period between the end of the 1950s and the middle of the 1980s, while consistently taking the most recent research into account. That they sometimes must abbreviate their findings does not damage the positive opinion of this pioneering study.

  11. Characterizing interannual variability of glacier dynamics and dynamic discharge (1999-2015) for the ice masses of Ellesmere and Axel Heiberg Islands, Nunavut, Canada

    Landsat 7 and RADARSAT-1/RADARSAT-2 satellite images are used to produce the most comprehensive record of glacier motion in the Canadian High Arctic to date and to characterize spatial and temporal variability in ice flow over the past ~15 years. This allows us to assess whether dynamically driven glacier change can be attributed to "surging" or "pulsing," or whether other mechanisms are involved. RADAR velocity mapping allows annual regional dynamic discharge (iceberg calving) to be calculated for 2000 and the period 2011-2015 (yielding a mean regional discharge of 2.21 ± 0.68 Gt a-1), and velocities derived from feature tracking of optical imagery allow for annual dynamic discharge to be calculated for select glaciers from 1999 to 2010. Since ~2011, several of the major tidewater-terminating glaciers within the region have decelerated and their dynamic discharge has decreased. Trinity and Wykeham Glaciers (Prince of Wales Icefield) represent a notable departure from this pattern as they have generally accelerated over the study period. The resulting increase in dynamic discharge from these glaciers entirely compensates (within error limits) for the decrease in discharge from the other tidewater glaciers across the study region. These two glaciers accounted for ~62% of total regional dynamic discharge in winter 2015 (compared to ~22% in 2000), demonstrating that total ice discharge from the Canadian High Arctic can be sensitive to variations in flow of just a few tidewater glaciers.

    2010-01-01

    This article comments on the paper by Rene Jahiel and Marcia Joslyn Scherer elsewhere in this issue. This article adds theoretical constructs. In commenting on their paper, this article makes four broad points. First, the sub-components identified by Drs. Jahiel and Scherer comprise critical factors of disability and the environment that must be taken into account when examining personal interactions with the environment. Second, as important as these factors are, operationalization of the model is hindered by a lack of mutual exclusivity between the sub-components both within and between the disability and environmental components. Third, power can be assessed in terms of the relative strength of individual functioning versus environmental functioning via a systematic appraisal of those elements essential to understanding the concept of accessibility. Finally, the demographic distinction between cohort and period trend analysis is an important consideration to take into account when assessing the time dimension, as the authors urge.

  14. Prebiotic chemistry in clouds

    Science.gov (United States)

    Oberbeck, Verne R.; Marshall, John; Shen, Thomas

    1991-01-01

    The chemical evolution hypothesis of Woese (1979), according to which prebiotic reactions occurred rapidly in droplets in giant atmospheric reflux columns was criticized by Scherer (1985). This paper proposes a mechanism for prebiotic chemistry in clouds that answers Scherer's concerns and supports Woese's hypothesis. According to this mechanism, rapid prebiotic chemical evolution was facilitated on the primordial earth by cycles of condensation and evaporation of cloud drops containing clay condensation nuclei and nonvolatile monomers. For example, amino acids supplied by, or synthesized during entry of meteorites, comets, and interplanetary dust, would have been scavenged by cloud drops containing clay condensation nuclei and would be polymerized within cloud systems during cycles of condensation, freezing, melting, and evaporation of cloud drops.

  7. Evidence for universality in phenomenological emotion response system coherence.

    Science.gov (United States)

    2007-02-01

    The authors reanalyzed data from Scherer and Wallbott's (Scherer, 1997b; Scherer & Wallbott, 1994) International Study of Emotion Antecedents and Reactions to examine how phenomenological reports of emotional experience, expression, and physiological sensations were related to each other within cultures and to determine if these relationships were moderated by cultural differences, which were operationally defined using Hofstede's (2001) typology. Multilevel random coefficient modeling analyses produced several findings of note. First, the vast majority of the variance in ratings was within countries (i.e., at the individual level); a much smaller proportion of the total variance was between countries. Second, there were negative relationships between country-level means and long- versus short-term orientation for numerous measures. Greater long-term orientation was associated with lowered emotional expressivity and fewer physiological sensations. Third, at the individual (within-culture) level, across the 7 emotions, there were consistent and reliable positive relationships among the response systems, indicating coherence among them. Fourth, such relationships were not moderated by cultural differences, as measured by the Hofstede dimensions.

  9. Informational basis of sensory adaptation: entropy and single-spike efficiency in rat barrel cortex.

    Science.gov (United States)

    Adibi, Mehdi; Clifford, Colin W G; Arabzadeh, Ehsan

    2013-09-11

    We showed recently that exposure to whisker vibrations enhances coding efficiency in rat barrel cortex despite increasing correlations in variability (Adibi et al., 2013). Here, to understand how adaptation achieves this improvement in sensory representation, we decomposed the stimulus information carried in neuronal population activity into its fundamental components in the framework of information theory. In the context of sensory coding, these components are the entropy of the responses across the entire stimulus set (response entropy) and the entropy of the responses conditional on the stimulus (conditional response entropy). We found that adaptation decreased response entropy and conditional response entropy at both the level of single neurons and the pooled activity of neuronal populations. However, the net effect of adaptation was to increase the mutual information because the drop in the conditional entropy outweighed the drop in the response entropy. The information transmitted by a single spike also increased under adaptation. As population size increased, the information content of individual spikes declined but the relative improvement attributable to adaptation was maintained.

  10. Systematics of strength function sum rules

    Science.gov (United States)

    Johnson, Calvin W.

    2015-11-01

    Sum rules provide useful insights into transition strength functions and are often expressed as expectation values of an operator. In this letter I demonstrate that non-energy-weighted transition sum rules have strong secular dependences on the energy of the initial state. Such non-trivial systematics have consequences: the simplification suggested by the generalized Brink-Axel hypothesis, for example, does not hold for most cases, though it weakly holds in at least some cases for electric dipole transitions. Furthermore, I show the systematics can be understood through spectral distribution theory, calculated via traces of operators and of products of operators. Seen through this lens, violation of the generalized Brink-Axel hypothesis is unsurprising: one expects sum rules to evolve with excitation energy. Furthermore, to lowest order the slope of the secular evolution can be traced to a component of the Hamiltonian being positive (repulsive) or negative (attractive).

  11. Systematics of strength function sum rules

    Sum rules provide useful insights into transition strength functions and are often expressed as expectation values of an operator. In this letter I demonstrate that non-energy-weighted transition sum rules have strong secular dependences on the energy of the initial state. Such non-trivial systematics have consequences: the simplification suggested by the generalized Brink–Axel hypothesis, for example, does not hold for most cases, though it weakly holds in at least some cases for electric dipole transitions. Furthermore, I show the systematics can be understood through spectral distribution theory, calculated via traces of operators and of products of operators. Seen through this lens, violation of the generalized Brink–Axel hypothesis is unsurprising: one expects sum rules to evolve with excitation energy. Furthermore, to lowest order the slope of the secular evolution can be traced to a component of the Hamiltonian being positive (repulsive) or negative (attractive).

    Innovative ideas blossom at the KT Entrepreneurship meet-ups.   Industrial control systems can be used in smart urban farms, for example for aquaponics. (Image: Exodes Urbains) The CERN Knowledge Transfer (KT) entrepreneurship meet-ups (or EM-Us) are the ideal place to discuss entrepreneurship and innovation at CERN. The latest inspiring story comes from a former CERN robotics engineer, Axel Voitier, who worked in the Engineering department. Having worked nearly a decade on managing data coming from the industrial control systems on the LHC, now he will be focusing on the data to help manage “smart urban farms”. Indeed, Axel is currently setting up a company dedicated to this new type of farming, an internet-of-things approach where control systems are used to manage urban farms automatically. “Data is the new petrol,” says Axel, “but I am interested in having a direct impact on the final users. This is why the security aspect is vital, because ev...

  20. Stochastic dynamics of super­paramagnetic moments in poli­disperse ferrofluids

    Science.gov (United States)

    Scherer, C.

    2007-12-01

    In previous works, we studied the dynamics of the magnetic moments in ferrofluids te{schererBJP,scherer-matuttis, scherer-ricci}, and other authors have also dealt with this problem te{shliomis}. In our previous works also computational simulations have been performed. The present work differs from those in two important aspects: (i) the magnetic particles are not of uniform size, but have a lognormal distribution of diameters; (ii) the parameters used in the simulations, like magnetization, anisotropy constant, liquid viscosity, applied field, temperature, etc., correspond to the values for realistic ferrofluids (in the previous works we used values, which were convenient for the simulations). For this reason, we will briefly re-derive the equations of motion, keeping all the relevant constants in them. To avoid big powers of 10 in the simulations, we introduce an appropriate system of units. The equations of motion for the particles' rotation and for the rotation of their magnetic moments are stochastic differential equations with multiplicative noise. Therefore, they have to be interpreted as Stratonovich-Langevin equations and the roles of stochastic calculus have to be used in the simulations. In our simulations, the response functions are "measured" and from them the complex susceptibilities are calculated. We performed several simulations, varying each parameter around a standard value, in order to see how the susceptibilities are correlated with the physical constants of the material. In the conclusions of special mention is the verification that the line broadening is very big. To be explicit, the ratio of the line-width of the polydisperse to that of the monodisperse with a diameter equal to the median diameter of the polydisperse, is much bigger than the ratio of the diameter's distribution width to the median diameter. It is interesting to note that for small dispersion width of diameters the resonance frequency does not change significantly with

    2005-06-01

    Cultural variations in the associations of 12 body sensations with 7 emotions were studied in 2 rural samples from northern Mexico (n = 61) and Java, Indonesia (n = 99), with low exposure to Western influences and in 3 university student samples from Belgium (n = 75), Indonesia (n = 85), and Mexico (n = 123). Both parametric and nonparametric analyses suggest that findings from previous studies with only student samples (K. R. Scherer & H. G. Wallbott, 1994) were generalizable to the 2 rural samples. Some notable cultural deviations from common profiles were also identified. Implications of the findings for explanations of body sensations experienced with emotions and the cross-cultural study of emotions are discussed.

    We experimentally study of the growth of Bose-Einstein condensates in harmonic trapping potentials with laser-induced perturbations to the potential well. We find that some time- independent perturbations can significantly impact the growth process and final state of the BEC. In particular, in numerical simulations and our experiments, we have observed the generation of vortices and vortex-antivortex pairs as a result of creating BECs in perturbed potentials. We will describe the results of our ongoing and completed experiments (D.R. Scherer, C.N. Weiler, T.W. Neely, B.P. Anderson, cond-mat/0610187, to be published in Phys. Rev. Lett.).

  9. Anerkennung und Arbeitslosigkeit

    Directory of Open Access Journals (Sweden)

    Gottfried Schweiger

    2011-12-01

    Full Text Available This paper aims to explore the case of unemployment from the perspective of recognition theory as it was conceived by Axel Honneth. In the first part I present a shortened form of recognition theory and afterwards, in the second part, its take on work and labor in modern societies. Finally, the third part elaborates how unemployment can be understood and evaluated from this viewpoint. I argue that unemployment itself is not a form of misrecognition and therefore not moral evil. But what has to be criticized are the negative effects of unemployment and the degrading treatment of unemployed people.

  10. Stein and Honneth on Empathy and Emotional Recognition

    DEFF Research Database (Denmark)

    Jardine, James Alexander

    2015-01-01

    My aim in this paper is to make use of Edith Stein’s phenomenological analyses of empathy, emotion, and personhood to clarify and critically assess the recent suggestion by Axel Honneth that a basic form of recognition is affective in nature. I will begin by considering Honneth’s own presentation...... of this claim in his discussion of the role of affect in recognitive gestures, as well as in his notion of ‘elementary recognition,’ arguing that while his account contains much of value it also generates problems. On the basis of this analysis, I will try to show that Stein’s account of empathy demarcates...

    Full Text Available Actual trends of worldwide railway transport development are characterized by increasing speed and growth of railway’s axels load. Increasing load together with transverse, longitudinal wheel displacement and braking on the rails results into heavy surface tension. One of many applications for bainitic steel is in railway transport for highly strength and wear resistant rails. Rail steel must be designed to be able to resist plastic deformation, wear, rolling contact fatigue, bending stress and thermal stress during rail welding process and rails resurfacing.

  1. Towards critical aspects of Confucianism

    Directory of Open Access Journals (Sweden)

    Dunaj Ľubomír

    2016-12-01

    Full Text Available This paper consists of two parts. The first deals with the issue of whether it is possible to coherently employ the term ‘critical Confucian’ in general, i.e. whether it is a paradox or oxymoron. It will be argued that Confucianism should not be identified with any particular ideology and, therefore, can be critical. This critical potential, in turn, can be developed by bringing it into dialogue with Critical Theory. As such, the second part indicates, in an introductory way, some possible overlaps between Confucianism and Critical Theory by comparing Heiner Roetz’s and Axel Honneth’s respective interpretations of these traditions.

  5. DESIGN AND DEVELOPMENT OF ONDANSETRON ORALLY DISINTEGRATING TABLETS AND ITS OPTIMIZATION USING DESIGN OF EXPERIMENT

    Directory of Open Access Journals (Sweden)

    Rakesh Kumar Bhasin et al.

    2012-03-01

    Full Text Available Ondansetron is the first of a new class of drugs, selective serotonin receptor antagonist (5 hydroxy tryptamine type 3 used as an anti emetic associated with cancer chemotherapy. Its Orally Disintegrating Tablet has been developed for patients who find swallowing difficult by freeze dried technology by RP Scherer Corporation and Scherer DDS. The aim of this study was to design a new orally disintegrating tablet that has high hardness and a fast disintegration rate using conventional tablet technology. Ondansetron ODT was prepared by using traditional technology like direct compression and wet granulation technique. As blend exhibited poor flow in direct compression process, so wet granulation process was finalized. Bitter taste of Ondansetron has been masked by use of sweetener like aspartame and peppermint flavor. Quick disintegration has been achieved by use of surfactant in the granulating solvent and superdisintegrant like crospovidone in both intra and extragranular part. Design space has been created by use of different concentrations of both binders as well as disintegrant with the help of DOE and a robust formulation has been made. In vitro release profile of both formulations prepared by freeze drying and wet granulation is matching. Formulation prepared by wet granulation process has been found acceptable to volunteers in term of taste, mouth feel and convenience of administration.

    To evaluate the prevalence of oral precancerous lesions in textile workers. A cross-sectional study was undertaken to assess a total of 1167 textile factory workers randomly selected from a total of 6947. An overall 97 women and 1070 men aged 18-69 years (mean=31.8 years) were studied. Regular smoking during the past 6 months was considered as the smoker group. Leukoplakia lesions were classified in accordance to Axell criteria [Axell T, Pindborg JJ, Smith CJ and Van-der-waal I (1996). J Oral Pathol Med 25: 49]. The results showed that 115 workers (9.9%) had red and white lesions. Among these 43 positive detections (3.7%) had leukoplakia and six cases (0.5%) had lichen planus. The smoking habits of the workers were limited to cigarette smoking. There was a statistically significant positive correlation between tobacco smoking and oral leukoplakia (P<0.001). There was a statistically significant positive correlation between tobacco smoking and leukoplakia in this relatively young cohort with generally mild tobacco use. The prevalence of leukoplakia had an inverse relationship with the level of education.

  13. Occurrence and distribution of bacterial tetraether lipids in the Eocene Canadian Arctic paleosols: paleoclimate implications (Invited)

    Mehay, S.; Jahren, A.; Schubert, B.; Eberle, J. J.; Summons, R. E.

    2010-12-01

    The Early to Middle Eocene (~56-45 Ma) was a “greenhouse” interval with average global temperatures warmer than any other time in the Cenozoic. This period was characterized by warm climates at high latitude leading to lush forests and the arrival of new mammal groups north of the Arctic Circle (>73°N). Glycerol dialkyl glycerol tetraethers (GDGTs) are membrane-spanning lipids characteristic of certain archaea and bacteria and it has been demonstrated that branched and cyclic GDGTs derived from soil bacteria vary in structure as a function of environmental factors. Proxies based on the relative abundances of methyl branched and cyclopentyl bacterial tetraethers are hypothesized to correlate with mean annual air temperature and soil pH. Here we present the occurrence and distribution of GDGTs in a range of paleosol and sediment samples from Axel Heiberg Island and Ellesmere Island, Nunavut (eastern Canadian Arctic) and Banks Island in the Northwest Territories (western Canadian Arctic). Preliminary results on 11 paleosol samples from the middle Eocene-aged Geodetic Hills Fossil Forest on Axel Heiberg Island indicate a mean annual air temperature of about 9°C. Earlier paleotemperature estimates for Axel Heiberg Island led to values ranging from 9°C to 15°C for the Middle Eocene. Recent temperature prediction for Ellesmere Island (Early Eocene) based upon oxygen isotope ratios of biogenic phosphate from mammal and fish fossils led to ~8°C. In contrast, GDGTs from a marine sedimentary sequence from Lomonosov Ridge in the central Arctic Ocean led to much higher Early Eocene temperature. Thus, the evaluation of the paleotemperature for the Early to Middle Eocene is still a subject of controversy. Ongoing GDGTs analysis of samples from Ellesmere and Banks Islands should give a more comprehensive paleoenvironmental description of the Eocene Arctic. Differences observed between the various paleotemperature estimates will also be discussed. GDGTs distributions are

    Science.gov (United States)

    Nguwi, Yok-Yen; Cho, Siu-Yeung

    2010-12-01

    This study discusses the computational analysis of general emotion understanding from questionnaires methodology. The questionnaires method approaches the subject by investigating the real experience that accompanied the emotions, whereas the other laboratory approaches are generally associated with exaggerated elements. We adopted a connectionist model called support-vector-based emergent self-organising map (SVESOM) to analyse the emotion profiling from the questionnaires method. The SVESOM first identifies the important variables by giving discriminative features with high ranking. The classifier then performs the classification based on the selected features. Experimental results show that the top rank features are in line with the work of Scherer and Wallbott [(1994), 'Evidence for Universality and Cultural Variation of Differential Emotion Response Patterning', Journal of Personality and Social Psychology, 66, 310-328], which approached the emotions physiologically. While the performance measures show that using the full features for classifications can degrade the performance, the selected features provide superior results in terms of accuracy and generalisation.

  15. Astute observations in their analysis of modifying existing person--environment interaction theory in disability.

    Science.gov (United States)

    Fox, Michael H

    2010-01-01

    Jahiel and Scherer point out very astutely that time can be a baffling confounder in viewing disability, taxing our ability to meaningfully apply the International Classification of Function, Disability and Health (ICF) model to outcomes analysis. Their approach to segmenting person and environment is constructive. But distilling factors based upon an a priori self-determination of disability as part of the model may also undercut the validity of the larger construct. While the authors are to be applauded for their efforts to extend existing models of disability to address their current shortcomings, attention must also be given to important socio- or geo-political factors that may deserve more than a contextual discussion and their own place in this developing theory.

  16. A review on solar wind modeling: kinetic and fluid aspects

    Echim, Marius; Lie-Svendsen, Oystein

    2013-01-01

    We review the main advantages and limitations of the kinetic exospheric and fluid models of the solar wind (SW). We discuss the hydrostatic model imagined by Chapman, the first supersonic hydrodynamic models published by Parker and the first generation subsonic kinetic model proposed by Chamberlain. It is shown that a correct estimation of the electric field as in the second generation kinetic exospheric models developed by Lemaire and Scherer, provides a supersonic expansion of the corona, reconciling the hydrodynamic and the kinetic approach. The third generation kinetic exospheric models considers kappa velocity distribution function (VDF) instead of a Maxwellian at the exobase and in addition they treat a non-monotonic variation of the electric potential with the radial distance; the fourth generation exospheric models include Coulomb collisions based on the Fokker--Planck collision term. Multi-fluid models of the solar wind provide a coarse grained description and reproduce with success the spatio-tempor...

  17. Pure states, positive matrix polynomials and sums of hermitian squares

    CERN Document Server

    Klep, Igor

    2009-01-01

    Let M be an archimedean quadratic module of real t-by-t matrix polynomials in n variables, and let S be the set of all real n-tuples where each element of M is positive semidefinite. Our key finding is a natural bijection between the set of pure states of M and the cartesian product of S with the real projective (t-1)-space. This leads us to conceptual proofs of positivity certificates for matrix polynomials, including the recent seminal result of Hol and Scherer: If a symmetric matrix polynomial is positive definite on S, then it belongs to M. We also discuss what happens for non-symmetric matrix polynomials or in the absence of the archimedean assumption, and review some of the related classical results. The methods employed are both algebraic and functional analytic.

    The present study focuses on the synthesis, microstructural and magnetic properties of ternary FeNiCo nanoparticles. Nanocrystalline ternary FeNiCo particles were synthesized via hydrogen reduction assisted ultrasonic spray pyrolysis method in single step. The effect of precursor concentration on the morphology and the size of particles was investigated. The syntheses were performed at 800 °C. Structure, morphology and magnetic properties of the as-prepared products were characterized through X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and vibrating sample magnetometer (VSM) studies. Scherer calculation revealed that crystallite size of the ternary particles ranged between 36 and 60 nm. SEM and TEM investigations showed that the particle size was strongly influenced by the precursor concentration and Fe, Ni, Co elemental composition of individual particles was homogeneous. Finally, the soft magnetic properties of the particles were observed to be a function of their size.

    Full Text Available This paper presents the result of a study on processes of interaction and mobilization identified in students in a Mathematics Degree attendance course using resources from the virtual learning environment. The focus of this study is on the mobilization of curricular knowledge under a perspective of pedagogical practice in interaction established with the use of chat and diary. The analysis was based on Thompson (2004, Primo (2008, Silva (2010, Scherer (2005, Charlot (2000, among others. Results reveal that there was mobilization of knowledge through mutual interactions and the existence of a learning reflective movement which implied conceptual construction, that the integration of tools available in virtual environments to the attendance environment optimized communication and the interaction between teacher students and among students, broadening the learning processes beyond the space and time of lessons, creating the effect of an ‘expanded classroom’.

    Full Text Available high purity fluorapatite (FA with rod-like and spherical-like morphology was synthesized via sol-gel method. Chemical characterization of FA powders was done by XRD and FTIR analyses. Crystallite samples were calculated using Scherer method. Morphology of FA powders was investigated with TEM and SEM images. The results revealed that increasing the time of hydrolysis of phosphate sols significantly decreased the gelation time of FA sols. Also, mixing temperature of P and Ca sols affects the gelation time of samples and increasing pH decreases the gelation time of FA sols. Morphological and chemical characterization of samples showed that the FA powders have high purity and rod-like and spherical-like morphology.

In Section 3 we give a broad outline of how the formulae can be obtained and in Section 4 we draw some quite precise conclusions about the asymptotic form of the formulae for general n.

    We have experimentally studied the merging of three trapped Bose-Einstein condensates. We find that, depending on the rate of merging, the final single BEC may contain a single vortex core (for slow merging rates), or multiple cores (for fast merging rates). Similarly, a triple-well trap may initiate the formation of three isolated BECs, but if the barriers between the wells are weak enough, the condensates merge together during their growth; this process can also lead to the formation of vortices in the final BEC. We interpret both scenarios in terms of interference between the initial uncorrelated condensates with indeterminate relative phases. We will discuss the results and interpretation of this experiment (D.R. Scherer, C.N. Weiler, T.W. Neely, B.P. Anderson, cond-mat/0610187, to be published in Phys. Rev. Lett.).

    By studying the dynamics of the Bose-Einstein condensation transition in highly oblate (˜11:1 aspect ratio) traps, we have measured the dependence of spontaneous vortex formation on BEC growth rate, extending our previous experimental and numerical observations of spontaneous vortex formation in weakly oblate (˜2:1 aspect ratio) traps [1]. Our condensation procedure in these highly oblate traps allows us to create BECs over a large range of growth times, from approximately 200 ms to over 2 s. By characterizing vortex formation vs. BEC growth rate, and comparing experimental and numerical results, the Kibble-Zurek mechanism for topological defect formation may be quantitatively studied in our system.

  4. Neuroscience in Nazi Europe part I: eugenics, human experimentation, and mass murder.

    2011-09-01

    The Nazi regime in Germany from 1933 to 1945 waged a veritable war throughout Europe to eliminate neurologic disease from the gene pool. Fueled by eugenic policies on racial hygiene, the Nazis first undertook a sterilization campaign against "mental defectives," which included neurologic patients with epilepsy and other disorders, as well as psychiatric patients. From 1939-41 the Nazis instead resorted to "euthanasia" of many of the same patients. Some neuroscientists were collaborators in this program, using patients for research, or using extracted brains following their murder. Other reviews have focused on Hallervorden, Spatz, Schaltenbrand, Scherer, and Gross, but in this review the focus is on neuroscientists not well described in the neurology literature, including Scholz, Ostertag, Schneider, Nachtsheim, and von Weizsäcker. Only by understanding the actions of neuroscientists during this dark period can we learn from the slippery slope down which they traveled, and prevent history from repeating itself.

    The calcium ferrite nano-particles (CaFe2O4 NPs) were synthesized using a sol-gel method for targeted drug delivery application. The proposed nano-particles were initially prepared by mixing calcium and iron nitrates that were added with citric acid in order to prevent agglomeration and subsequently calcined at a temperature of 550°C to obtain small particle size. The prepared nanoparticles were characterized by using an XRD (X-ray diffraction), which revealed the configuration of orthorhombic structures of the CaFe2O4 nano-particles. A crystallite size of ~13.59 nm was obtained using a Scherer's formula. Magnetic analysis using a VSM (Vibrating Sample Magnetometer analysis), revealed that the synthesized particles exhibited super-paramagnetic behavior having magnetization saturation of approximately 88.3emu/g. Detailed observation via the scanning electron microscopy (SEM) showed the calcium ferrite nano-particles were spherical in shape.

    Nano-crystalline undoped and Mg doped ZnO (Mg-ZnO) nanoparticles with compositional formula Mg{sub x}Zn{sub 1-x}O (x=0,1,3,5,7,10 and 12 %) were synthesized using sol-gel process. The XRD diffraction peaks match with the pattern of the standard hexagonal structure of ZnO that reveals the formation of hexagonal wurtzite structure in all samples. SEM images demonstrates clearly the formation of spherical ZnO nanoparticles, and change of the morphology of the nanoparticles with the concentration of the magnesium, which is in close agreement with that estimated by Scherer formula based on the XRD pattern. To investigate the doping effect on optical properties, the UV–VIS absorption spectra was obtained and the band gap of the samples calculated.

    Highlights: Black-Right-Pointing-Pointer The deformation of the mechanically alloyed Cu-Fe powder is anisotropic. Black-Right-Pointing-Pointer The Rietveld method is more proper and results in smaller crystallite size than the Scherer and Williamson-Hall methods. Black-Right-Pointing-Pointer A dual phase super saturated solid solution achieved after 96 h of milling of the mixtures with 30, 50 and 70 wt.% of Iron. Black-Right-Pointing-Pointer A final proportion of approximately 85% FCC and 15% BCC structure obtained in all of the applied compositions. - Abstract: In this study, the formation of super saturated solid solution in the binary Cu-Fe system was investigated. Three powder blends with 30, 50 and 70 wt.% of Fe were milled for different times to 96 h. The variations of lattice parameter and inter-planar spacing were calculated and analyzed using X-ray diffraction analysis (XDA). The anisotropy of lattice deformation in the FCC phase was studied and the obtained results were compared to milled pure Cu powder. Furthermore, crystallite size was calculated using Scherer formula in comparison with Rietveld full profile refinement method. Considering the previous studies about the formation of non-equilibrium FCC and BCC phases, the phase evolution has been discussed and the proportion of each phase was calculated using Rietveld refinement method. Supplementary studies on the evolution of microstructure and formation of solid solution were carried out using high resolution transmission electron microscopy (HRTEM). Finally, high angle annular dark field (HAADF) imaging was utilized to find out the level of homogeneity in the resulting phases. While true alloying takes place in each phase, the final structure consists of both FCC and BCC nano-crystallites.

    Full Text Available Resumen: El presente ensayo contiene dos partes. En la primera se hace una breve descripción de las carencias de la reflexión moral a las que parece venir al encuentro el concepto de reconocimiento. Charles Taylor y Axel Honneth, protagonistas en estos debates, dan buenas razones para dirigir la discusión hacia el tema del reconocimiento, pero no coinciden ni en su definición, ni en el modo de recuperar la tesis de Hegel, ni tampoco en la forma de tratar la relación entre autonomía y reconocimiento. En la segunda parte se analiza la concepción propiamente hegeliana, con la intención de destacar el nexo esencial, no la ruptura, que existe entre la noción de reconocimiento y el modelo conceptual de la voluntad libre o del espíritu.

    Full Text Available TAF is the acronym for Articulated Forestry Tractor – a heavy vehicle uses in a logging operation for pulling cut trees out of a forest, in a process called “skidding”. TAF use a cardan shafts transmission from the gear box (CV to distribution box (CD. The distribution box split the movement thru axels or winch. The study applied the cardan theory on a specific case and based on the numeric results a few design modifications are proposed for reducing the angular velocity pulse on the CD input shaft. Theoretical results may have a significant importance in practice, impacting the reduction of transmission noise and vibrations - already claimed in the case of the distribution box for the current constructive solution. An original AutoLISP program are made in order to analyze and optimize the transmission, with graphical results.

    Full Text Available This essay aims to extend Paul Ricœur’s account of recognition to address some of the concerns of globalization, especially those voiced by Enrique Dussel. The extension is accomplished in two parts.  First, Dussel’s account of spatial existence as dwelling is reviewed as it is pertinent to the concerns of globalization.  Next, it is demonstrated that each of the aspects of Ricœur’s account of recognition may be given a spatial re-articulation.  The results thus establish an outline of how recognition theory might address some of the concerns of globalization.  The essay concludes with several consequences for the modification of recognition politics as one finds it in the late work of Ricœur and in Axel Honneth’s ongoing inquiries.

    2011-01-01

    Radial forging is a multi purpose incremental forging process using four tools on the same plane. It is widely used for the forming of tool steels, super alloys as well as titanium- and refractory metals. The range of application goes from reducing the diameters of shafts, tubes, stepped shafts and axels, as well as for creating internal profiles for tubes in Near-Net-Shape and Net-Shape quality. Based on actual development of a weight optimized transmission input shaft, the specific features of radial forging technology is demonstrated. Also a Finite Element Model for the simulation of the process is shown which leads to reduced pre-processing effort and reduced computing time compared to other published simulation methods for radial forging. The finite element model can be applied to quantify the effects of different forging strategies.

    Full Text Available Social networking sites made possible through Web 2.0 allow for unique user-generated tags called “searchable signatures.”  These tags move beyond the descriptive and act as means for users to assert online individual and group identities.  A study of searchable signatures on the Instagram application demonstrates that these types of tags are valuable not only because they allow for both individuals and groups to engage in what social theorist Axel Honneth calls the struggle for recognition, but also because they provide contextual use data and sociohistorical information so important to the understanding of digital objects.  This article explores how searchable signatures might be used by both patrons and staff in library environments.

    We describe here a simple digital in-line holographic microscope (DIHM) that was used to investigate the microbial life forms that exist in perennial springs and glacial melt-water pools on Axel Heiberg Island at near 80°N latitude in the Canadian High Arctic. The instrument determined an upper limit of the density of microbial organisms in the springs and also found an abundance of algae and bacteria in the pools formed from glacial run off. The discovery of life in extra-terrestrial regions of our solar system has been the aim of several space missions. DIHM can capture the dynamics of objects throughout an imaging volume with wavelength limited resolution. The simplicity of DIHM technology furthermore allows the construction of very light-weight and rugged instruments that we believe can be easily adapted for space missions and exobiological studies.

Tecemos, assim, uma costura entre Foucault e a primeira geração da Escola de Frankfurt, que se apoia inicialmente na crítica de Honneth tanto a um quanto a outro, para em seguida ultrapassá-la, mostrando, ao mesmo tempo, os pontos em comum – centrados na crítica radical da razão – e os motivos para considerá-los responsáveis por empreitadas filosóficas distintas.

  5. Between Ideology and Utopia: Honneth and Ricoeur on Symbolic Violence, Marginalization and Recognition

    Marianne Moyaert

    2011-06-01

    Full Text Available This article focuses on multiculturalism in the context of present-day societies and the need to incorporate minorities within a reframed social order. In his critical theory, Axel Honneth rightly draws attention to the idea of the moral grammar of struggles for recognition.  Analyzing his theory in depth, the article shows that Honneth underestimates the violent power of ideological discourse in marginalizing and excluding society’s others, e.g. cultural minorities. It then puts forward an alternative approach based on Ricœur’s creative and original reflections on ideology and utopia. For the incorporation of cultural minorities to occur, the symbolic order of society needs to be critiqued, transformed and expanded. From this perspective, the author highlights the subversive and transformative strength of utopian counter-narratives. The latter form a vital resource for cultural minorities in their struggle for recognition.

From the standpoint of theoretical and methodological work this study is located, in the wake of recent social theory, in the developments of the social recognition category, whose use is associated to the postcritical theory by Charles Taylor, Nancy Fraser, and Axel Honneth. This approach allows the configuration of a useful tool in understanding the discursive formation of public policy, particularly ProJovem, whose goal highlights on the one hand, symbolic recognition by emphasizing the role of youth and the equal participation of the community, and on the other hand, in recognition distributive, through education and work initiation.

Throughout especially the earlier parts of his work, Goffman however also advanced a much more Durkheimian inspired view of social life that rests on the idea...... that human everyday encounters are characterised as much by rituals and ritual care than by cynical or shallow self-presentations. The main content of this ritual metaphor therefore consists of the notion that a variety of almost unnoticed minor courtesies and microscopic civilities such as facework...... and civil inattention guide the conduct of people in many of their face-to-face encounters with each other.

    The modern theory of the atomic nucleus results from the merging of the liquid drop (Niels Bohr and Fritz Kalckar) and of the shell model (Marie Goeppert Meyer and Axel Jensen), which contributed the concepts of collective excitations and of independent-particle motion respectively. The unification of these apparently contradictory views in terms of the particle-vibration (rotation) coupling (Aage Bohr and Ben Mottelson) has allowed for an ever increasingly complete, accurate and detailed description of the nuclear structure, Nuclear Field Theory (NFT, developed by the Copenhagen-Buenos Aires collaboration) providing a powerful quantal embodiment. In keeping with the fact that reactions are not only at the basis of quantum mechanics (statistical interpretation, Max Born) , but also the specific tools to probe the atomic nucleus, NFT is being extended to deal with processes which involve the continuum in an intrinsic fashion, so as to be able to treat them on an equal footing with those associated with discret...

  14. Comparison of vitrified and unvitrified Eocene woody tissues by TMAH thermochemolysis – implications for the early stages of the formation of vitrinite

    Full Text Available Abstract Samples of vitrified and unvitrified Eocene woody plant tissues collected from the Fossil Forest site, Geodetic Hills, Axel Heiberg Island, have been characterized by TMAH thermochemolysis. All samples are gymnosperm-derived, are of very low maturity and all share the same post-depositional geologic history. Differences in the distributions of products observed from vitrified and unvitrified samples suggest that vitrification of woody tissue is associated with modification of the lignin C3 side chain, following loss of all or most of the carbohydrate present in the precursor woody tissues. The key driver of vitrification appears to be physical compression of the tissue following biological removal of cellulosic materials.

    Full Text Available The paper examines one possible argument against restricting the display of religious icons in Romanian public schools. Opponents of this decision claim that cult objects affirm something essential about our cultural identity and therefore that using legal instruments to protect this identity is justified.Using a differential analysis of two models of identity recognition, Charles Taylor’s and Axel Honneth’s, this paper argues that the legal protection of cultural identity is compatible with value pluralism but only if its defense is justified in the terms provided by Honneth’s theory of identity recognition. However, the argument in favor of displaying icons in Romanian public schools, unlike the argument against wearing the Islamic veil in French public schools, cannot be justified in these terms.

    This study aimed to analyze perceptions of conflict between workers and managers in primary healthcare units and to present a typology of conflicts on the job. This was a comprehensive interpretive case study with a critical hermeneutic approach. Data collection techniques included: focus group with managers, workplace observation, and worker interviews, conducted from April to November 2011. The results were triangulated and indicated the coexistence of distinct concepts of conflict, typified in six modalities: lack of collaboration at work; disrespect resulting from asymmetrical relations between workers; problematic employee behavior; personal problems; asymmetry with other management levels; and inadequate work infrastructure. The relevance of (non)mutual recognition, as proposed by Axel Honneth, stood out in the interpretation of the causes and practical implications of these conflicts.

Abstract:This essay is divided into two parts. The first one is a short description of the deficiencies of moral reflection, which seem to lead the discussion towards the concept of recognition. Charles Taylor and Axel Honneth, two of the protagonists of these debates, give very good reasons for turning the argument towards the issue of recognition, but they do not agree on its definition, on the way to recover the Hegelian thesis, or on how to approach the relationship between autonomy and recognition. The second part constitutes an analysis of the Hegelian conception of recognition, in order to highlight the essential link –rather than the rupture– between the notion of recognition and the conceptual model of free will or spirit.

    Full Text Available Unemployment is one of the greatest social problems all around the world including in modern capitalistic welfare states. Therefore its social critique is a necessary task for any critical social philosophy such as Axel Honneth's recognition approach, which understands social justice in terms of social conditions of recognition. This paper aims to develop an evaluation of unemployment and its moral weight from this perspective. I will lay out the recognition approach and present a moral evaluation of unemployment as socially unjust based on the knowledge of its negative consequences for those affected. I will then discuss two objections to this conclusion, namely that a mere correlation of suffering and moral wrongness is not enough and that there are legitimate differences in the experience of recognition which could justify the existence of unemployment as deserved. In the next section, I will then refute both objections and first show that unemployment can be understood as socially unjust based on the knowledge that it is involuntary and that the unemployed are not responsible for their condition. Then I will discuss the relationship between the idea of meritocracy and unemployment to examine the assumption of unemployment as being deserved. I will finally conclude that unemployment is not a necessary side effect of meritocracy and that there are good reasons to argue for a moral and justified obligation to provide an actual access to paid work for all who want to work. However, such changes face serious obstacles and are not likely to happen under the current interpretation of meritocracy and social esteem which are one-sided and flawed.

Cuestiona ante todo el carácter abstracto o formal de la teoría moral que se da en la Ética del Discurso, que remite finalmente a Habermas a Kant. Honneth, por su lado, se apoya en el joven y casi materialista Hegel de Jena y en el behaviorista G. H. Mead, para proponer una teoría de la sociedad, no ajena a lo empírico, que contenga sustancia normativa (normativ gehaltvoll, equidistante del formalismo de la ética comunicativa y de la materialidad del comunitarismo, superando así las dos tendencias, la universalista y la relativista, con el fin de mediarlas.Axel Honneth asks himself if the concept of recognition can assume the function that Jürgen Habermas had attributed to the concept of communication. Thus he places himself in a critical position regarding the thinking tradition he belonged to-the critic theory. He questions the abstract or formal character of the moral theory of the Ethics of Discourse, which ultimately leads to Habermas and Kant. Honneth, on his side, seeks support in the young and almost materialist Hegel of Jena and in the behaviorist G. H. Mead to propose a theory of society, not altogether unempirical, somehow normative (normativ gehaltvoll, equidistant from the formalism of communicative ethics and from the materiality of "communitarism", and going beyond both universalism and relativism.

    Full Text Available This text of Mary Shelley permits the possibility of considering the character of the «Creature» from the Axel Honneth`s perspective of the Ethics of reconnaissance. From this point of view, the dramatic sense of this novel moves round identity´s problem. The essential condition to build identity is the recognition from each to other. That is why identity can not be obtain in the sense of solitarious consciousness, but requires of intersubjetivity. The Creature becomes deprived of recognition, even by Frankenstein who has created him. This Creature becomes perverse because this privation, when the most elemental right of human being so as being someone and having an identity, is denied to him. His wickedness is the secondary effect of exclusion and suffering.

Por eso la identidad no se puede adquirir en el plano subjetivo de la conciencia solitaria sino que precisa de la intersubjetividad . La criatura se ve privada de reconocimiento, incluso por parte de Frankenstein, que lo ha engendrado. Esa privación, al negarle el derecho más elemental del ser humano, que es ser alguien y tener una identidad, lo vuelve perverso. Su maldad es el efecto secundario de la marginación y el sufrimiento.

    Lower Carboniferous (Mississippian) coal beds and oil shale occur at several locations in northern Canada. In the northern Yukon Territory coal of semi-anthracite/anthracite rank occurs in the Kayak Formation in the British Mountains and at Hoidahl Dome near the headwaters of Blow River. Farther south in the Liard Basin, Northwest Territories, coals of high volatile bituminous rank occur in the Mattson Formation. In the Arctic Islands thicker beds of the Emma Fiord Formation, the oldest unit in the Sverdrup Basin, contain thin coal seams and oil shale on Devon Island, near the southern edge of the basin and on Axel Heiberg and Ellesmere islands on the north side of the basin. Organic matter in the Devon Island section is at a low maturity level (R[sub o, max] % 0.26-0.50), whereas that from Ellesmere and Axel Heiberg has reached the level of meta-anthracite. Depositional environments for these carbonaceous sediments were different. The coal-bearing Kayak strata accumulated in a coastal plain setting overlain transgressively by younger marine beds. The Mattson coal beds appear to have formed in a prograding delta, but coal and oil shale in the Emma Ford were deposited in lacustrine environments in a rift basin. These Canadian occurrences resemble penecontemporaneous deposits in Svalbard and elsewhere, adjacent to the present-day Arctic Ocean. They formed at low latitudes where conditions were favourable for the preservation of carbonaceous matter. Prior to the opening of the Arctic Ocean basin in Mesozoic times, sites on the mainland were undoubtedly closer to sites in the Arctic Islands than they are today.

    Full Text Available This study aimed to describe the neuromuscular activity of elite athletes who performed various roller figure skating jumps, to determine whether the muscle activation is greater during jumps with more rotations and in which phase the muscles are more active. This study also aimed to analyze if there is any difference in the muscle activity pattern between female and male skaters. Four elite skaters were evaluated, and each participated in two experimental sessions. During the first session, anthropometric data were collected, and the consent forms were signed. For the second session, neuromuscular data were collected during jumps, which were performed with skates at a rink. The following four roller figure skating jumps were evaluated: single Axel, double Axel, double Mapes and triple Mapes. The neuromuscular activity of the following seven muscles was obtained with an electromyograph which was fixed to the waist of each skater with a strap: biceps femoris, lateral gastrocnemius, tibialis anterior, rectus femoris, vastus lateralis, vastus medialis and gluteus maximus. The signal was transmitted wirelessly to a laptop. During the roller figure skating jumps, the lateral gastrocnemius, rectus femoris, vastus lateralis, biceps femoris and gluteus maximus, showed more activation during the jumps with more rotations, and the activation mainly occurred during the propulsion and flight phases. Female skaters demonstrated higher muscle activities in tibialis anterior, vastus lateralis, vastus medialis and gluteus maximus during the landing phase of the triple Mapes, when compared to their male counterparts. The results obtained in this study should be considered when planning training programs with specific exercises that closely resemble the roller figure skating jumps. This may be important for the success of elite skaters in competitions.

    Highlights: • Ce-substituted spinel ferrites synthesized by coprecipitation route have been investigated. • The average particle size was in the range of 30.8–63.7 nm estimated by Scherer formula. • Saturation magnetization values were decreased with increasing Ce contents. • Coercivity for all samples is suitable for recording media, switching and EM materials. - Abstract: Nanocrystalline samples of Ce{sup 3+} substituted Co–Cr ferrite with chemical formula CoCr{sub 0.04}Ce{sub x}Fe{sub 1.96−x}O{sub 4} (0 ⩽ x ⩽ 0.1) have been synthesized by co-precipitation method and sintered at a temperature of 850 °C for 8 h. The samples were characterized using thermo-gravimetric and differential thermal analysis, X-ray diffraction, Fourier transform infrared spectroscopy, Raman spectroscopy, scanning electron microscopy, atomic force microscopy and vibrating sample magnetometry. The XRD patterns and FTIR spectra confirm that the prepared samples reveal the formation of spinel ferrites. The average particle size was found to be in the range of 30.8–63.7 nm estimated by Scherer formula. The lattice constant varies in the range of 8.352–8.382 Å due to difference in the ionic radii of the substituted cations. IR studies confirm two main absorption bands in the frequency range of 400–800 cm{sup −1} arising due to the tetrahedral (A-site) and octahedral (B-site) stretching vibrations. The elemental analysis as obtained from the EDXS measurement is in close agreement with the expected composition from the stoichiometry of the reactant solutions. The M–H loops show that the saturation magnetization decreased gradually with increasing Ce content, while the coercivity is related to the microstructure of Ce-substituted samples. The obtained results suggest that the investigated materials are potential candidates for magnetic recording media, security, switching and high frequency applications.

  13. PERMEABILITY OF SALTSTONE MEASUREMENT BY BEAM BENDING

    2008-01-30

    One of the goals of the Saltstone variability study is to identify (and, quantify the impact of) the operational and compositional variables that control or influence the important processing and performance properties of Saltstone mixes. A performance property for Saltstone mixes that is important but not routinely measured is the liquid permeability or saturated hydraulic conductivity of the cured Saltstone mix. The value for the saturated hydraulic conductivity is an input into the Performance Assessment for the SRS Z-Area vaults. Therefore, it is important to have a method available that allows for an accurate and reproducible measurement of permeability quickly and inexpensively. One such method that could potentially meet these requirements for the measurement of saturated hydraulic conductivity is the technique of beam bending, developed by Professor George Scherer at Princeton University. In order to determine the feasibility of this technique for Saltstone mixes, a summer student, David Feliciano, was hired to work at Princeton under the direction of George Scherer. This report details the results of this study which demonstrated the feasibility and applicability of the beam bending method to measurement of permeability of Saltstone samples. This research effort used samples made at Princeton from a Modular Caustic side solvent extraction Unit based simulant (MCU) and premix at a water to premix ratio of 0.60. The saturated hydraulic conductivities for these mixes were measured by the beam bending technique and the values determined were of the order of 1.4 to 3.4 x 10{sup -9} cm/sec. These values of hydraulic conductivity are consistent with independently measured values of this property on similar MCU based mixes by Dixon and Phifer. These values are also consistent with the hydraulic conductivity of a generic Saltstone mix measured by Langton in 1985. The high water to premix ratio used for Saltstone along with the relatively low degree of hydration for

    In space, the weightless environment provides a different stimulus to the otolith organs of the vestibular system, and the resulting signals no longer correspond with the visual and other sensory signals sent to the brain. This signal conflict causes disorientation. To study this and also to understand the vestibular adaptation to weightlessness, DARA has developed scientific equipment for vestibular and visuo-oculomotoric investigations. Especially, two video-oculography systems (monocular--VOG--and binocular--BIVOG, respectively) as well as stimuli such as an optokinetic stimulation device have successfully been employed onboard MIR in the frame of national and European missions since 1992. The monocular VOG was used by Klaus Flade during the MIR '92 mission, by Victor Polyakov during his record 15 months stay onboard MIR in 1993/94 as well as by Ulf Merbold during EUROMIR '94. The binocular version was used by Thomas Reiter and Sergej Avdeyev during the 6 months EUROMIR '95 mission. PIs of the various experiments include H. Scherer and A. Clarke (FU Berlin), M. Dieterichs and S. Krafczyk (LMU Munchen) from Germany as well as C.H. Markham and S.G. Diamond from the United States. Video-Oculography (VOG) is a technique for examining the function of the human balance system located in the inner ear (vestibular system) and the visio-oculomotor interactions of the vestibular organ. The human eye movements are measured, recorded and evaluated by state-of-the-art video techniques. The method was first conceived and designed at the Vestibular Research Laboratory of the ENT Clinic in Steglitz, FU Berlin (A. Clarke, H. Scherer). Kayser-Threde developed, manufactured and tested the facilities for space application under contract to DARA. Evaluation software was first provided by the ENT Clinic, Berlin, later by our subcontractor Sensomotoric Instruments (SMI), Teltow. Optokinetic hardware to support visuo-oculomotoric investigations, has been shipped to MIR for EUROMIR '95

    Full Text Available The political theory of corporate social responsibility (CSR claims that the current social role of multinational corporations can not be described merely with the classic and economic CSR paradigms which are based on an instrumentalist view where the various corporate stakeholders are considered in decision-making only in as much as they are powerful and able to influence the profit of the corporation (Scherer and Palazzo 2011. Scherer and Palazzo suggest that the CSR activities can be discussed from an alternative perspective. Instead of analyzing corporate responsibility from an economic or an ethical point of view, they propose to embed the CSR debate in the context of the changing order of political institutions. Based on the Habermasian understanding of lifeworld and system world, the dialogues and other corporate social responsibility practices, such as voluntary programs, staff involvement and the use of social media for the purpose of stakeholder relation strengthening, are the solutions that facilitate the possibility to bring together the lifeworld and the system world through the formation of organisation’s internal openness. Thus the initiatives of stakeholder dialogues are intended to ensure that the interest alignment between companies and stakeholder organisations is between two collective agents and occurs along the mutually agreed criteria. When we take a closer look at the corporate practice, in the case of stakeholder involvement, the companies largely determine with which stakeholders to initiate dialogue. Companies that put an emphasis on environmental and social aspects are equally valued by their investors; the Dow Jones Sustainability Index (www.sustainability-indices.com for example, grades companies from the point of view of sustainability as a stock indicator. Therefore, ethical decisions have strategic purposes too. In order to describe the characteristic patterns of companies, stakeholder relations and social

    The Sverdrup Basin is an east-west-trending extensional sedimentary basin underlying the northern Canadian Arctic Archipelago. The tectonic history of the basin began with Carboniferous-Early Permian rifting followed by thermal subsidence with minor tectonism. Tectonic activity rejuvenated in the Hauterivian-Aptian by renewed rifting and extension. Strata were deformed by diapiric structures that developed during episodic flow of Carboniferous evaporites during the Mesozoic and the basin contains igneous components associated with the High Arctic Large Igneous Province (HALIP). HALIP was a widespread event emplaced in multiple pulses spanning ca. 180 to 80 Ma, with igneous rocks on Svalbard, Franz Josef Island, New Siberian Islands, and also in the Sverdrup Basin on Ellef Ringnes, Axel Heiberg, and Ellesmere islands. Broadly contemporaneous igneous activity across this broad Arctic region along with a reconstructed giant radiating dyke swarm suggests that HALIP is a manifestation of large mantle plume activity probably centred near the Alpha Ridge. Significant surface uplift associated with the rise of a mantle plume is predicted to start ~10-20 my prior to the generation of flood basalt magmatism and to vary in shape and size subsequently throughout the LIP event (1,2,3) Initial uplift is due to dynamical support associated with the top of the ascending plume reaching a depth of about 1000 km, and with continued ascent the uplift topography broadens. Additional effects (erosion of the ductile lithosphere and thermal expansion caused by longer-term heating of the mechanical lithosphere) also affect the shape of the uplift. Topographic uplift can be between 1 to 4 km depending on various factors and may be followed by subsidence as the plume head decays or become permanent due to magmatic underplating. In the High Arctic, field and geochronological data from HALIP relevant to the timing of uplift, deformation, and volcanism are few. Here we present new evidence

  17. Los climas políticos y las responsabilidades filosóficas: La lección de Cassirer sobre Filosofía y Política (1944

    Full Text Available In his speech of 1944 on Philosophy and Politics, Ernst Cassirer puts forward an idea that will be revisited in The Myth of the State and prevails in a good part of his works. Philosophy must be accountable for promoting certain political climates, such as what happened with some thinkers who favoured the consolidation of Nazism. Thought crises may generate social or political turbulences, because in these circumstances there is a continuous dialectic between thinkers and people of action, between ideas and facts, summing up, between theory and praxis. The main historic-political problems cannot be solved without taking into account the fundamental questions approached from a philosophical perspective, because there is an unavoidable interaction between the structure of ideas and our socio-political reality. The Davos’s debate, The idea of the Republican Constitution, The problem Jean-Jacques Rousseau and Moral Philosophy, Rights and Metaphysics: A dialogue with Axel Hägerstrom are presented in order to illustrate this thesis defended by the author of this paper, who has also written La Quimera del Rey Filósofo (The Chimera of the Philosopher King.

    En su conferencia de 1944 sobre Filosofía y Política Ernst Cassirer expone algo que será retomado por El mito del Estado y preside buena parte de su obra. La filosofía debe rendir cuentas en cuanto responsable indirecta de ciertos climas políticos, tal como sucedió con ciertos pensadores que propiciaron la consolidación del nazismo. Las crisis de pensamiento pueden generar convulsiones políticas o sociales, porque se da una continua dialéctica entre pensadores y hombres de acción, entre las ideas y los hechos, en definitiva, entre la teoría y la práctica. Los grandes problemas histórico-políticos no pueden resolverse sin atender a las cuestiones fundamentales abordadas desde una perspectiva filosófica, toda vez que se da una insoslayable interacción entre la estructura de

    Full Text Available O debate sobre os direitos das uniões homoafetivas constitui um dos tópicos mais controversos do direito constitucional. Como se sabe, a união homoafetiva não foi reconhecida expressamente no § 3º do artigo 226 da CF, inexistindo norma específica. O presente artigo pretende investigar a posição de ministros do STF em relação ao tema das uniões homoafetivas, em conexão com as filosofias do reconhecimento propostas por Axel Honneth e Nancy Fraser. Nesse sentido, os fundamentos filosóficos das teorias do reconhecimento podem ser um instrumental teórico fundamental para a compreensão de determinadas formas de ativismo judicial que objetivam a proteção de minorias estigmatizadas cujas pretensões normativas são desconsideradas pelo processo político. Pretendemos demonstrar que o paradigma da autorrealização proposto por Honneth é impreciso e incapaz de legitimar formas de ativismo judicial voltadas para a proteção dos direitos das uniões homoafetivas.The homosexual union rights are debated as one of the most controversial topics of Constitutional Law. It is known that the homosexual union was not explicitly recognized by the article 226 § 3º from FC, as there is no specific regulation for this subject. This paper intends to investigate STF ministers' position in relation to homosexual union according to Axel Honneth and Nancy Fraser philosophies of recognition. In this sense, the philosophical basis from recognition theories may be a theoretical instrument to comprehend some forms of judicial activism which aims are to protect stigmatized minorities whose regulatory intentions are disregarded by the political process. We intend to demonstrate that the Honneth's paradigm of achievement is imprecise and can't legitimate forms of judicial activism aimed to protect the rights of homosexual unions.

    Full Text Available Christina Scherer weist in ihrer Dissertation die strukturelle Äquivalenz zwischen einer essayistischen Filmästhetik und dem Prozess des Erinnerns auf. Ivens, Marker, Godard und Jarman thematisieren in und mit ihren Filmen die Unverfügbarkeit der Erinnerung und halten trotz ihres Zweifels an der Abbildbarkeit von Welt und ihrer Einsicht in die Uneinholbarkeit der Vergangenheit den Horizont der Möglichkeit von Erinnerung offen. In Essayfilmen sind es vor allem die selbstreflexive Selbstvergewisserung, die Einsicht in das unausweichliche Verfehlen der Vergangenheit und der melancholische Rückblick auf eine verloren gegangene Ganzheit, die einen fühlenden Verstand und ein denkendes Herz generieren.Christina Scherer’s dissertation points to the structural equivalence between the aesthetics of the essay film and the process of remembering. Ivens, Marker, Godard and Jarman make the unavailability of memory their central theme. Despite the filmmakers’ doubts about the possibility of replicating a true image of the world and their knowledge of the irretrievability of the past they nonetheless insist on the possibility of memory. Reflectively positioning oneself, acknowledging inevitable errors of the past, and looking back in melancholy on a lost entirety are some of the strategies in essay films which generate a sympathetic mind and a thinking heart.

    RF Sputtering system is one of the Physical Vapour Deposition (PVD) methods that have been widely used to produce hard coating. This technique is used to deposit thin layers of metallic substrates such as stainless steel (SS). From this process, a good adhesiveness and wear resistance coating can be produced for biomedical applications. In this study, RF sputtering method was used to deposit TiO{sub 2}-Ag composite coatings via various deposition parameters. The parameters are RF power of 350W, gas composition (Ar: O{sub 2}) 50:5 and deposition time at 1, 2, 4 and 6 hours. Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD) and Raman spectroscopy were used to characterize surface area of coated samples. The formation of nanocrystalline thin film and the surface morphology were examined using SEM. The crystallite size of TiO{sub 2}-Ag composite coatings were estimated between 20-60 nm based on XRD analysis using Scherer equation and SEM evaluation. The Raman and XRD results suggested that the structure of the TiO{sub 2}-Ag consist of anatase and rutile phases. It also showed that the intensity of anatase peaks increased after samples undergone annealing process at 500 Degree-Sign C.

    The predicted effects of climate change on surface temperatures are now emergent and quantifiable. The recent letter by Hansen and Sato (2016 Environ. Res. Lett. 11 034009) adds to a growing number of studies showing that warming over the past four decades has shifted the distribution of temperatures higher almost everywhere, with the largest relative effects on summer temperatures in developing regions such as Africa, South America, southeast Asia, and the Middle East (e.g., Diffenbaugh and Scherer 2011 Clim. Change 107 615-24 Anderson 2011 Clim. Change 108 581; Mahlstein et al 2012 Geophys. Res. Lett. 39 L21711). Hansen and Sato emphasize that although these regions are warming disproportionately, their role in causing climate change—measured by cumulative historical CO2 emissions produced—is small compared to the US and Europe, where the relative change in temperatures has been less. This spatial and temporal mismatch of climate change impacts and the burning of fossil fuels is a critical dislocation of interests that, as the authors note, has ‘substantial implications for global energy and climate policies.’ Here, we place Hansen and Sato’s ‘national responsibilities’ into a broader conceptual framework of problematically dislocated interests, and briefly discuss the related challenges for global climate mitigation efforts.

    Copper oxide nanoparticles were successfully prepared by a sol-gel technique. An aqueous solution of copper nitrate Cu(NO3)2 and acetic acid was used as precursor. On addition of sodium hydroxide (NaOH) a precipitate of copper oxide was immediately formed. The copper oxide nanoparticles were characterized by use of x-ray diffractometry (XRD), thermogravimetric analysis (TGA), differential thermal analysis, differential scanning calorimetry, Fourier-transform infrared spectroscopy (FTIR), vibrating sample magnetometry, and scanning electron microscopy (SEM). The XRD pattern contained sharp peaks of copper oxide nanoparticles with mixed cuprite and tenorite phases. Use of the Debye-Scherer equation showed that the crystallite size of the copper oxide nanoparticles increased with increasing annealing temperature. FTIR spectra revealed vibration of the CuO band at 473 cm-1; a band at 624 cm-1 was attributed to Cu2O. Maximum coercivity and saturation magnetization of the nanoparticles were 276 Oe and 0.034 emu/g, respectively. SEM micrographs of the nanoparticles revealed the presence of spherical nanoparticles of the tenorite phase whereas the cuprite phase was in the form of a compact deposit.

    Nanocrystalline samples of BaZr1- x Fe x O3 ( x = 0.0, 0.05, 0.10, 0.20, 0.30, 0.40 and 0.50) ceramics were synthesized by the wet chemical sol-gel auto combustion method. The perovskite structured cubic phase formation of BaZr1- x Fe x O3 samples was confirmed by x-ray diffraction (XRD) data analysis. Various structural parameters such as lattice constant ( a), unit cell volume ( V), x-ray density ( ρ x), and porosity ( P) were determined using XRD data. The lattice constant ( a), x-ray density ( ρ x) and porosity ( P) decrease with an increase in Fe content x. The average particle size was calculated by using the Debye-Scherer's formula using XRD data and was 9-18 nm. The microstructural studies were investigated through scanning electron microscopy technique. Compositional stoichiometry was confirmed by energy dispersive spectrum analysis. The direct current electrical resistivity studies of the prepared samples were carried out in the temperature range of 343-1133 K using a standard two-probe method. The electrical conductivity ( σ) increases with temperature and Fe concentration. The dielectric parameters such as dielectric constant ( ɛ') and loss tangent (tan δ) were measured with frequency at room temperature in the frequency range 50 Hz to 5 MHz. The dielectric parameters show strong compositional as well as frequency dependences. The dielectric parameters were found to be higher at lower frequency.

    2004-03-01

    Python is a modern object-oriented programming language. VPython (http://vpython.org) is a combination of Python (http://python.org), the Numeric module from LLNL (http://www.pfdubois.com/numpy), and the Visual module created by David Scherer, all of which have been under continuous development as open source projects. VPython makes it easy to write programs that generate real-time, navigable 3D animations. The Visual module includes a set of 3D objects (sphere, cylinder, arrow, etc.), tools for creating other shapes, and support for vector algebra. The 3D renderer runs in a parallel thread, and animations are produced as a side effect of computations, freeing the programmer to concentrate on the physics. Applications include educational and research visualization. In the Fall of 2003 Hugh Fisher at the Australian National University, John Zelle at Wartburg College, and I contributed to a new stereo capability of VPython. By adding a single statement to an existing VPython program, animations can be viewed in true stereo 3D. One can choose several modes: active shutter glasses, passive polarized glasses, or colored glasses (e.g. red-cyan). The talk will demonstrate the new stereo capability and discuss the pros and cons of various schemes for display of stereo 3D for a large audience. Supported in part by NSF grant DUE-0237132.

    VPython (http://cil.andrew.cmu.edu/projects/visual) combines the Python programming language with an innovative 3D graphics module called Visual, developed by David Scherer. Designed to make 3D physics simulations accessible to novice programmers, VPython allows the programmer to write a purely computational program without any graphics code, and produces an interactive realtime 3D graphical display. In a program 3D objects are created and their positions modified by computational algorithms. Running in a separate thread, the Visual module monitors the positions of these objects and renders them many times per second. Using the mouse, one can zoom and rotate to navigate through the scene. After one hour of instruction, students in an introductory physics course at Carnegie Mellon University, including those who have never programmed before, write programs in VPython to model the behavior of physical systems and to visualize fields in 3D. The Numeric array processing module allows the construction of more sophisticated simulations and models as well. VPython is free and open source. The Visual module is based on OpenGL, and runs on Windows, Linux, and Macintosh.

    Full Text Available Nickel oxide was deposited on highly cleaned glass substrates using spray pneumatic technique. The effect of precursor molarity on structural, optical and electrical properties has been studied. The XRD lines of the deposited NiO were enhanced with increasing precursor molarity due to the improvement of the films crystallinity. It was shown that the crystalline size of the deposited thin films was calculated using Debye-Scherer formula and found in the range between 9 and 47 nm. The optical properties have been discussed in this work. The absorbance (A, the transmittance (T and the reflectance (R were measured and calculated. Band gap energy is considered one of the most important optical parameter, therefore measured and found ranging between 3.64 and 3.86 eV. The NiO thin film reduces the light reflection for visible range light. The increase of the electrical conductivity to maximum value of 0.0896 (Ω cm – 1 can be explained by the increase in carrier concentration of the films. A good electrical conductivity of the NiO thin film is obtained due to the electrically low sheet resistance. NiO can be applied in different electronic and optoelectronic applications due to its high band gap, high transparency and good electrical conductivity.

    The classic work on laryngeal flow resistance by van den Berg et al. [J. Acoust. Soc. Am. 29, 626-631 (1957)] is revisited. These authors used a formula to summarize their measurements, and thus they separated the effects of entrance loss and pressure recovery from those of viscosity within the glottis. Analysis of intraglottal pressure distributions obtained from the physical model M5 [R. Scherer et al., J. Acoust. Soc. Am. 109, 1616-1630 (2001)] reveals substantial regions within the glottis where the pressure gradient is almost constant for glottal diameters from 0.005 to 0.16 cm, as expected when viscous effects dominate the flow resistance of a narrow channel. For this set of glottal diameters, the part of the pressure gradient that has a linear dependence on the glottal volume velocity is isolated. The inverse cube diameter of the Poiseuille expression for glottal flows is examined with the data set provided by the M5 intraglottal pressure distributions. The Poiseuille effect is found to give a reasonable account of viscous effects in the diameter interval from 0.0075 to 0.02 cm, but an inverse 2.59 power law gives a closer fit across all diameters.

    Cobalt substituted nanosized magnesium aluminates having a nominal composition MgAl{sub 2-x}Co{sub x}O{sub 4} where x = 0.0, 0.5, 1.0, 1.5, 2.0 were synthesized by the chemical co-precipitation method. Aluminium (Al{sup 3+}) ions were completely and successfully substituted by Co{sup 2+} ions, which yielded an electron rich terminal compound MgCo{sub 2}O{sub 4}. All the samples were characterized by means of X-ray diffraction (XRD), thermogravimetry and differential thermal analysis (TG/DTA) and dc electrical resistivity measurements. The investigated samples were found to be spinel single phase cubic close packed crystalline materials as demonstrated by XRD data. Using the Debye Scherer formula, the calculated crystallite size was found Co{sup 2+} concentration dependent and varied between 7 and 19 nm. The lattice constant, X-ray density and bulk density were found to increase while percentage porosity decreases on increasing the Co{sup 2+} concentration. The dc electrical resistivity was found to decrease as a function of temperature as expected for a typical semiconductor. The doped Co{sup 2+} ions are believed to form small polarons and hopping of these small polarons between the adjacent sites seems to be partially responsible for conduction in the system. The activation energy of hopping of small polarons was also calculated.

Despite its widespread clinical use, detailed information about cardiac side effects of midazolam is largely lacking. Using the double-electrode voltage clamp technique, we studied pharmacological effects of midazolam on heterologously expressed Kv1.5 channels underlying atrial repolarizing current IKur. Midazolam dose-dependently inhibited Kv1.5 current, yielding an IC50 of 17 µM in an HEK cell line and an IC50 of 104 µM in Xenopus oocytes. We further showed that midazolam did not affect the half-maximal activation voltage of Kv1.5 channels. However, a small negative shift of the inactivation curve could be observed. Midazolam acted as a typical open-channel inhibitor with rapid onset of block and without frequency dependence of block. Taken together, midazolam is an open channel inhibitor of cardiac Kv1.5 channels. These data add to the current understanding of the pharmacological profile of midazolam.Keywords: anesthetics, potassium channels, pharmacology

    In recent years there is a tremendous growth in the interdisciplinary world of nanotechnology across the globe and emergence of its potential applications remains as a big revolution to the industry. Fusion of green nanotechnology and medicine represents one of the major breakthroughs of modern science with the aim of developing nanomaterials for diagnosis, treatment, prevention of various diseases and overall improving health for the beneficial of mankind. In the present study phytofabrication of nickel nanoparticles (nickel NPs) was carried out by using indigenous Aegle marmelos Correa aqueous leaf extracts as a reducing, stabilizing and capping agents. Nickel NPs were characterized by UV-spectroscopy, FTIR, XRD, SEM, AFM and TGA studies. Phytosynthesis of nickel NPs was monitored both at room temperature (25°C) and at 60°C for 5h. The green synthesis of triangular shape nickel NPs phytofabricated from A. marmelos Correa aqueous leaf extracts having face centered cubic structure showing an average particle size of 80-100nm which is in consistent with the particle size calculated by XRD Scherer equation. We further explored and compared nickel NPs of A. marmelos Correa with crude leaf extracts of A. marmelos Correa for its in-vitro anti-inflammatory and mosquito larvicidal efficacy against three blood feeding parasites. The results obtained clearly gives an idea that nickel NPs of A. marmelos Correa (NiNPs of AmC) possess an enhanced anti-inflammatory and larvicidal activity when compared to crude leaf extracts of A. marmelos Correa.

This residual risk suggests that additional risk factors require aggressive modification to result in more effective prevention of cardiovascular disease. Hypertriglyceridemia has presented a considerable challenge with regard to understanding its role in the promotion of cardiovascular risk. Increasing evidence has established a clear causal role for elevated triglyceride levels in vascular risk. As a result, there is increasing interest in the development of specific therapeutic strategies that directly target hypertriglyceridemia. This has seen a resurgence in the use of omega-3 fatty acids for the therapeutic lowering of triglyceride levels. The role of these agents and other emerging strategies to reduce triglyceride levels in order to decrease vascular risk are reviewed.

    In present communication, structural, optical and electrical properties of nanostructured vanadium pentoxide (V2O5) have been investigated. UV-Visible spectroscopy measurements were carried out in order to investigate the optical properties of as grown V2O5 samples. UV-Visible absorption spectrum shows a shifting in absorption peak towards lower wavelength from pure to different concentrated as grown samples. Value of optical band-gap (Eg), estimated from optical measurements, increases from 2.89 to 3.38eV with increase in concentration. Nanostructured V2O5 samples were synthesized using cost effective sol-gel method and final product was sintered at different temperatures. X-ray diffraction (XRD) measurement was performed to investigate the structural phases present which revealing the single phasic nature with orthorhombic structure. Crystallite size (CS), calculated using Scherer's formula, is found to be ˜ 38.13 for 500°C sintered sample which increases to ˜ 51.31nm for higher temperature sintered sample. Improved CS leads to the decrease in crystal boundary density in the sample sintered at higher temperature. Electrical properties of nanostructured V2O5 were studied by carrying out dielectric and A.C. conductivity measurements. Dielectric and A.C. conductivity have been understood on the basis of CS, crystal boundaries and interaction between the mobile ions and lattice in the nanoparticles.

    The dispersion of particles in the human lung is modeled as a series of virtual mixing tanks. Using the experimental results of Scherer et al. (1975, J. Appl. Physiol., 38(4), pp. 719-723) for a five-generation glass lung model, it is shown that each generation of the glass lung behaves like an independent virtual mixing tank. The corresponding resident time distribution is shown to have a variance approximately equal to the square of the average time a particle spends in the generation. By assuming that each generation of the human lung behaves as an independent virtual mixing tank, the realistic lung data provided by Weibel (1963, Morphometry of the Human Lung, Spinger-Verlag, New York) are used to validate this assumption in two ways. First, the half-width of the exhaled particle concentration profile is obtained. Second, a system of differential equations, with the concentration of particles in each mixing tank as its solution, is derived and solved numerically. This gives the exhaled concentration profile. Both techniques yield similar results to each other, and both give excellent agreement with the experimental data. The virtual mixing tank approach allows the complex mixing that occurs in the branching pathways of the lung to be more simply modeled. The model, thereby derived, is simple to change and could lead to enhancements in the understanding of the underlying processes contributing to the ventilation of the lung in health and disease.

    O presente estudo tem como objetivo mapear as principais colaborações do pensamento social brasileiro acerca da luta organizada do negro ao longo da Primeira República, momento em que o povo negro se viu liberto da antiga sociedade de castas que o escravizava, mas no entanto estava fora do projeto da nova sociedade de classe que se formava. Daremos destaque à densa e original interpretação proposta por Florestan Fernandes em seu A integração do negro na sociedade de classes, elencando os principais fatores que diferenciam essa obra de todo o que já havia sido escrito sobre o negro até aquela época. Procuraremos demonstrar que não constitui exagero colocar o trabalho de Florestan entre os primeiros estudos de caráter pós-colonial sobre a luta pela emancipação do negro brasileiro, uma vez que desenvolve suas análises a partir da dimensão simbólica e psicossocial revelada pelo discurso dos próprios sujeitos do movimento, metodologia que ainda estava em desenvolvimento pela nascente Teoria dos Novos Movimentos Sociais. Para tanto, nos guiaremos pelos trabalhos de analistas como Octavio Ianni (2004, Jessé Sousa (2000, Sérgio Tavolaro (2005 e Ilse Scherer-Warren (2010.

    RF Sputtering system is one of the Physical Vapour Deposition (PVD) methods that have been widely used to produce hard coating. This technique is used to deposit thin layers of metallic substrates such as stainless steel (SS). From this process, a good adhesiveness and wear resistance coating can be produced for biomedical applications. In this study, RF sputtering method was used to deposit TiO2-Ag composite coatings via various deposition parameters. The parameters are RF power of 350W, gas composition (Ar: O2) 50:5 and deposition time at 1, 2, 4 and 6 hours. Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD) and Raman spectroscopy were used to characterize surface area of coated samples. The formation of nanocrystalline thin film and the surface morphology were examined using SEM. The crystallite size of TiO2-Ag composite coatings were estimated between 20-60 nm based on XRD analysis using Scherer equation and SEM evaluation. The Raman and XRD results suggested that the structure of the TiO2-Ag consist of anatase and rutile phases. It also showed that the intensity of anatase peaks increased after samples undergone annealing process at 500 °C.

    CdS nanoparticles (NPs) passivated with amino acids (L-alanine and L-arginine) having spherical hierarchical morphology were synthesized by room temperature wet chemical method. Synthesized NPs were characterized by ultraviolet-visible (UV-vis) spectroscopy to study the variation of band gaps with concentration of surface modifying agents. Increase in band gap has been observed with the increase in concentration of surface modifying agents and was found more prominent for CdS NPs passivated with L-alanine. Powder X-ray diffraction (XRD) and transmission electron microscopy (TEM) analysis were carried out for the study of crystal structure and morphology of CdS NPs. The average particle size of CdS NPs calculated from Debye-Scherer formula was found to less than 5 nm and agrees well with those determined from UV-vis spectra and TEM data. Fourier transform infrared (FT-IR) spectroscopy was performed to know the functional groups of the grown NPs. Peaks in FT-IR spectra indicate the formation of CdS NPs and capping with L-alanine and L-arginine. Photoluminescence spectra of these NPs were also studied. Finally, colloidal solution of CdS-PVAc was subjected to Z-scan experiment under low power cw laser illumination to characterize them for third order nonlinear optical properties. CdS-PVAc colloidal solution shows enhanced nonlinear absorption due to RSA and weak FCA on account of two photon absorption processes triggered by thermal effect.

    Nickel zinc ferrite nanoparticles with diameters less than 20 nm were synthesized by co-precipitation method. The synthesized nanoparticles were annealed at 500 °C. Two types of samples (powder and disk) were prepared. The disk sample was prepared by pressing the powder sample. Magnetic and structural properties of the products were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and alternating gradient-force magnetometer (AGFM). The X-ray analysis shows that the formation of the synthesized nickel zinc ferrite is spinell. The average crystalline size for nickel zinc ferrite powder was found around 19 nm (calculated by Debye-Scherer formula).The formation, size and the uniformity of the samples were determined by TEM. It was found that the size of nanoparticles should be around 18 nm from the SEM image. AGFM diagrams shows that the magnetization of the powder sample at the 9 kOe is 21.5 emu/g that of disk sample is 33 emu/g. Therefore, the magnetization was increased by pressing the nickel zinc ferrite nanoparticles. Sensor sensitivity of this disk ferrite is investigated in an isolated box. For this purpose, the samples are injected to this box and six gases (ethanol, methanol, chloroform, acetonitrile, acetone and methane) are exposed to the ferrite by a mechanical gate. The acetonitrile had the best sensitivity performance.

    This paper presents a new asset allocation model based on the CVaR risk measure and transaction costs. Institutional investors manage their strategic asset mix over time to achieve favorable returns subject to various uncertainties, policy and legal constraints, and other requirements. One may use a multi-period portfolio optimization model in order to determine an optimal asset mix. Recently, an alternative stochastic programming model with simulated paths was proposed by Hibiki [N. Hibiki, A hybrid simulation/tree multi-period stochastic programming model for optimal asset allocation, in: H. Takahashi, (Ed.) The Japanese Association of Financial Econometrics and Engineering, JAFFE Journal (2001) 89-119 (in Japanese); N. Hibiki A hybrid simulation/tree stochastic optimization model for dynamic asset allocation, in: B. Scherer (Ed.), Asset and Liability Management Tools: A Handbook for Best Practice, Risk Books, 2003, pp. 269-294], which was called a hybrid model. However, the transaction costs weren't considered in that paper. In this paper, we improve Hibiki's model in the following aspects: (1) The risk measure CVaR is introduced to control the wealth loss risk while maximizing the expected utility; (2) Typical market imperfections such as short sale constraints, proportional transaction costs are considered simultaneously. (3) Applying a genetic algorithm to solve the resulting model is discussed in detail. Numerical results show the suitability and feasibility of our methodology.

    Nanostructured SnO{sub 2} hollow microspheres were synthesized using ultrasonic atomization technique. It is interesting that hollow microspheres could be prepared from ultrasonic atomization technique without any aid of template and surfactant. X-ray powder diffraction (XRD) confirmed the material to be SnO{sub 2} having tetragonal structure. Average crystallite size calculated from X-ray diffractogram using Scherer's equation was found to be 8.45 nm. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were used to study the microscopic study of fine powder particles. Powder consists of hollow microspheres of average diameter of 0.58 {mu}m as well as nanoparticles of average diameter of 6 nm. The sensors fabricated from such powder show high hydrogen (1000 ppm) response (S = 2379) under the optimized experimental conditions. Sensor performance merits, such as, high hydrogen response, high hydrogen selectivity, short response time (2 s) and quick recovery time (15 s) may be due to both nanocrystallites and hollow microspheres associated in SnO{sub 2} sensing material. The dramatic change in gas response was explained by the rapid diffusion of the target gas through the nano-porous structure of SnO{sub 2} hollow microspheres.

    Materials reduced to the Nano scale can exhibit different properties compared to what they exhibit on a micro scale, enabling unique applications. When TiO2 is reduced to Nano scale it shows unique properties, of which the electrical aspect is highly important. This paper presents increase in the energy gap and decrease in conductivity with decrease in particle size of pure Nano TiO2 synthesized by hydrolysis and peptization of titanium isopropoxide. Aqueous solution with various pH and peptizing the resultant suspension will form Nano TiO2 at different particle sizes. As the pH of the solution is made acidic reduction in the particle size is observed. And it is confirmed from XRD using Scherer formula and SEM, as prepared samples are studied for UV absorbance, and DC conductivity from room temperature to 400°C. From the tauc plot it was observed, and calculated the energy band gap increases as the particle size decreases and shown TiO2 is direct band gap. From Arrhenius plot clearly we encountered, decrease in the conductivity for the decrease in particle size due to hopping of charge carriers and it is evident that, we can tailor the band gap by varying particle size.

    An important requisite for improving risk communication practice related to contentious environmental issues is having a better theoretical understanding of how risk perceptions function in real-world social systems. Our study applied Scherer and Cho's social network contagion theory of risk perception (SNCTRP) to cormorant management (a contentious environmental management issue) in the Great Lakes Basin to: (1) assess contagion effects on cormorant-related risk perceptions and individual factors believed to influence those perceptions and (2) explore the extent of social contagion in a full network (consisting of interactions between and among experts and laypeople) and three "isolated" models separating different types of interactions from the full network (i.e., expert-to-expert, layperson-to-layperson, and expert-to-layperson). We conducted interviews and administered questionnaires with experts (e.g., natural resource professionals) and laypeople (e.g., recreational and commercial anglers, business owners, bird enthusiasts) engaged in cormorant management in northern Lake Huron (n = 115). Our findings generally support the SNCTRP; however, the scope and scale of social contagion varied considerably based on the variables (e.g., individual risk perception factors), actors (i.e., experts or laypeople), and interactions of interest. Contagion effects were identified more frequently, and were stronger, in the models containing interactions between experts and laypeople than in those models containing only interactions among experts or laypeople.

  7. Coherence explored between emotion components: evidence from event-related potentials and facial electromyography.

    Componential theories assume that emotion episodes consist of emergent and dynamic response changes to relevant events in different components, such as appraisal, physiology, motivation, expression, and subjective feeling. In particular, Scherer's Component Process Model hypothesizes that subjective feeling emerges when the synchronization (or coherence) of appraisal-driven changes between emotion components has reached a critical threshold. We examined the prerequisite of this synchronization hypothesis for appraisal-driven response changes in facial expression. The appraisal process was manipulated by using feedback stimuli, presented in a gambling task. Participants' responses to the feedback were investigated in concurrently recorded brain activity related to appraisal (event-related potentials, ERP) and facial muscle activity (electromyography, EMG). Using principal component analysis, the prediction of appraisal-driven response changes in facial EMG was examined. Results support this prediction: early cognitive processes (related to the feedback-related negativity) seem to primarily affect the upper face, whereas processes that modulate P300 amplitudes tend to predominantly drive cheek region responses.

    Kondrachuk, A. V.; Sirenko, S. P.

    Caloric stimulation of the semicircular canal SC is widely applied in studies of vestibular impairments Barany 1906 suggested that caloric response of SC results from mechanism of endolymph convection due to density changes of endolymph and therefore depends on the action of gravity forces However the Skylab experiments 1983 showed that the caloric reaction of SC can take place even under microgravity The studies of Scherer Clarke 1985 Harada Ariki 1985 Baumgarten et al 1985 considered the thermal expansion of endolymph to be a concurrent mechanism The model of caloric response based on the buoyancy force due to density change in the endolymph induced by thermal stimulation was proposed by Gentine et al 1990 1991 It should be noted that the first qualitative model that took into account the effect of endolymph thermal expansion under local heating to analyze the properties of primary afferents was proposed by Gusev Orlov 1977 However these models failed to answer the question which of the mentioned effects will be dominant under certain conditions The purpose of present study was to account for the expansion and convection of endolymph and to determine under which conditions one mechanism dominates over the other The consideration is based on the following model of SC Kondrachuk Sirenko 1990 an isolated torus filled by a compressible viscous Newton liquid endolymph the torus interior is plugged by an elastic body cupula the cupula surface in contact with endolymph is supposed to be stretched along the

  9. Levels of Valence

    The distinction between the positive and the negative is fundamental in our emotional life. In appraisal theories, in particular in the component process model of emotion (Scherer, 1984, 2010), qualitatively different types of valence are proposed based on appraisals of (un)pleasantness, goal obstructiveness/conduciveness, low or high power, self-(in)congruence, and moral badness/goodness. This multifaceted conceptualization of valence is highly compatible with the frequent observation of mixed feelings in real life. However, it seems to contradict the one-dimensional conceptualization of valence often encountered in psychological theories, and the notion of valence as a common currency used to explain choice behavior. Here, we propose a framework to integrate the seemingly disparate conceptualizations of multifaceted valence and one-dimensional valence by suggesting that valence should be conceived at different levels, micro and macro. Micro-valences correspond to qualitatively different types of evaluations, potentially resulting in mixed feelings, whereas one-dimensional macro-valence corresponds to an integrative “common currency” to compare alternatives for choices. We propose that conceptualizing levels of valence may focus research attention on the mechanisms that relate valence at one level (micro) to valence at another level (macro), leading to new hypotheses, and addressing various concerns that have been raised about the valence concept, such as the valence-emotion relation.

    A simple combustion method has been tried for the preparation of nanoparticle-sized LiBiO2 powder with urea as the igniter and glycerol as the binding material. Nitrates of Li+ and Bi3+ were mixed together to form a uniform mixture. Required quantities of urea and glycerol were added to this mixture to form a paste. This paste was carefully heated to 100°C initially and finally heated to 460°C for 5 h. The product obtained was subjected to TG/DTA and XRD analysis. The particle size of the cathode material was roughly calculated from the X-ray data using Scherer equation. However, SEM and EDAX analysis were carried out in detail to confirm the particle size and the composition of LiBiO2 respectively. A 2016 coin type button cell was assembled with LiBiO2 as cathode and graphite as anode containing polypropylene separator and a solution of 1 M LiClO4 dissolved in 1:1 (EC+DEC) mixture as the electrolyte. Charge/discharge studies were conducted to establish viability of the reversible cell.

    Work on facial expressions of emotions (Calder, Burton, Miller, Young, & Akamatsu, [2001]) and emotionally inflected speech (Banse & Scherer, [1996]) has successfully delineated some of the physical properties that underlie emotion recognition. To identify the acoustic cues used in the perception of nonverbal emotional expressions like laugher and screams, an investigation was conducted into vocal expressions of emotion, using nonverbal vocal analogues of the "basic" emotions (anger, fear, disgust, sadness, and surprise; Ekman & Friesen, [1971]; Scott et al., [1997]), and of positive affective states (Ekman, [1992], [2003]; Sauter & Scott, [2007]). First, the emotional stimuli were categorized and rated to establish that listeners could identify and rate the sounds reliably and to provide confusion matrices. A principal components analysis of the rating data yielded two underlying dimensions, correlating with the perceived valence and arousal of the sounds. Second, acoustic properties of the amplitude, pitch, and spectral profile of the stimuli were measured. A discriminant analysis procedure established that these acoustic measures provided sufficient discrimination between expressions of emotional categories to permit accurate statistical classification. Multiple linear regressions with participants' subjective ratings of the acoustic stimuli showed that all classes of emotional ratings could be predicted by some combination of acoustic measures and that most emotion ratings were predicted by different constellations of acoustic features. The results demonstrate that, similarly to affective signals in facial expressions and emotionally inflected speech, the perceived emotional character of affective vocalizations can be predicted on the basis of their physical features.

    Full Text Available Axel Steiger, Marcel Pawlowski, Mayumi Kimura Max Planck Institute of Psychiatry, Munich, Germany Abstract: The sleep electroencephalogram (EEG provides biomarkers of depression, which may help with diagnosis, prediction of therapy response, and prognosis in the treatment of depression. In patients with depression, characteristic sleep EEG changes include impaired sleep continuity, disinhibition of rapid-eye-movement (REM sleep, and impaired non-REM sleep. Most antidepressants suppress REM sleep in depressed patients, healthy volunteers, and in animal models. REM suppression appears to be an important, but not an absolute requirement, for antidepressive effects of a substance. Enhanced REM density, a measure for frequency of REM, characterizes high-risk probands for affective disorders. REM-sleep changes were also found in animal models of depression. Sleep-EEG variables were shown to predict the response to treatment with antidepressants. Furthermore, certain clusters of sleep EEG variables predicted the course of the disorder for several years. Some of the predicted sleep EEG markers appear to be related to hypothalamic–pituitary–adrenal system activity.

    2016-12-01

    Bird fossils from Turonian (ca. 90 Ma) sediments of Axel Heiberg Island (High Canadian Arctic) are among the earliest North American records. The morphology of a large well-preserved humerus supports identification of a new volant, possibly diving, ornithurine species (Tingmiatornis arctica). The new bird fossils are part of a freshwater vertebrate fossil assemblage that documents a period of extreme climatic warmth without seasonal ice, with minimum mean annual temperatures of 14 °C. The extreme warmth allowed species expansion and establishment of an ecosystem more easily able to support large birds, especially in fresh water bodies such as those present in the Turonian High Arctic. Review of the high latitude distribution of Northern Hemisphere Mesozoic birds shows only ornithurine birds are known to have occupied these regions. We propose physiological differences in ornithurines such as growth rate may explain their latitudinal distribution especially as temperatures decline later in the Cretaceous. Distribution and physiology merit consideration as factors in their preferential survival of parts of one ornithurine lineage, Aves, through the K/Pg boundary.

    Our results to date indicate that CO2 and CH4 fluxes from organic poor, Arctic cryosols on Axel Heiberg Island are net CH4 sinks and CO2 emitters in contrast to organic-rich peat deposits at sub-Arctic latitudes. This is based upon field observations and a 1.5 year long thawing experiment performed upon one meter long intact cores. The results of the core thawing experiments are in good agreement with field measurements. Metagenomic, metatranscriptomic and metaproteomic analyses indicate that high affinity aerobic methanotrophs belong to the uncultivated USCalpha are present in <1% abundance in these cryosols are are active in the field during the summer and in the core thawing experiments. The methanotrophs are 100 times more abundant than the methanogens. As a result mineral cryosols, which comprise 87% of Arctic tundra, are net methane sinks. Their presence and activity may account for the discrepancies observed between the atmospheric methane concentrations observed in the Arctic predicted by climate models and the observed seasonal fluctuations and decadal trends. This has not been done yet.

    2016-01-01

    Gamma strength functions (GSFs) and level densities (LDs) are essential ingredients of statistical nuclear reaction theory with many applications in astrophysics, reactor design, and waste transmutation. The aim of the present work is a test of systematic parametrizations of the GSF recommended by the RIPL-3 data base for the case of $^{208}$Pb. The upward GSF and LDs in $^{208}$Pb are compared to gamma decay data from an Oslo-type experiment to examine the validity of the Brink-Axel (BA) hypothesis. The E1 and M1 parts of the total GSF are determined from high-resolution forward angle inelastic proton scattering data taken at 295 MeV at RCNP, Osaka, Japan. Total LDs in $^{208}$Pb are derived from $1^-$ LDs extracted with a fluctuation analysis in the energy region of the isovector giant dipole resonance. The E1 GSF is compared to parametrizations recommended by the RIPL-3 data base showing systematic deficiencies of all models in the energy region around neutron threshold. The new data for the poorly known s...

Its treatment outcome has been significantly improved over the last decade with the incorporation of biological targeted therapies, including anti-EGFR antibodies, cetuximab and panitumumab, and VEGF inhibitors, bevacizumab, ramucirumab, and aflibercept. The identification of predictive biomarkers has further improved the survival by accurately selecting patients who are most likely to benefit from these treatments, such as RAS mutation profiling for EGFR antibodies. Regorafenib is a multikinase inhibitor currently used as late line therapy for mCRC. The molecular and genetic markers associated with regorafenib treatment response are yet to be characterized. Here, we review currently available clinical evidence of mCRC molecular profiling, such as RAS, BRAF, and MMR testing, and its role in targeted therapies with special focus on regorafenib treatment.

    This project report summarizes the work I have been performing during the past twelve weeks as a Summer Student intern working on ROOT project in the SFT group, PH department, under the supervision of Axel Naumann and Danilo Piparo. One of the widely requested features for ROOT was improved interactive shell experience as well as improved printing of object values. Solving this issue was the goal of this project. Primarily, we have enabled printing of the collections. Secondly, we have unified the printing interface, making it much more robust and extendible. Thirdly, we have implemented printing of nested collections in a flexible and user-friendly manner. Finally, we have added an interactive mode, allowing for paginated output. At the beginning of the report, ROOT is presented with examples of where it is used and how important it is. Then, the motivation behind the project is elaborated, by presenting the previous state of the software package and its potential for improvement. Further, the process in wh...

    Bacterial growth at low pressure is a new research area with implications for predicting microbial activity in clouds and the bulk atmosphere on Earth and for modeling the forward contamination of planetary surfaces like Mars. Here, we describe experiments on the recovery and identification of 20 species of bacterial hypobarophiles (def., growth under hypobaric conditions of approximately 1-2 kPa) in 10 genera capable of growth at 0.7 kPa. Hypobarophilic bacteria, but not archaea or fungi, were recovered from diverse soils, and high numbers of hypobarophiles were recovered from Arctic and Siberian permafrost soils. Isolates were identified through 16S rRNA sequencing to belong to the genera Bacillus, Carnobacterium, Clostridium, Cryobacterium, Exiguobacterium, Paenibacillus, Rhodococcus, Streptomyces, and Trichococcus. The highest population of culturable hypobarophilic bacteria (5.1 × 104 cfu/g) was recovered from Colour Lake soils from Axel Heiberg Island in the Canadian Arctic. In addition, we extend the number of hypobarophilic species in the genus Serratia to six type-strains that include S. ficaria, S. fonticola, S. grimesii, S. liquefaciens, S. plymuthica, and S. quinivorans. Microbial growth at 0.7 kPa suggests that pressure alone will not be growth-limiting on the martian surface, or in Earth's atmosphere up to an altitude of 34 km.

    @@ 1Introduction Chiral recognition of substrates is one of the most characteristic phenomena of biological activity. And one of the most fundamental biological activities of chemical substances is their smell. In 1991, Linda Buck and Richard Axel[1] discovered a large multigene family that en codes odorant receptors, for which they were awarded the 2004 Nobel Prize in Medicine and Physiology. These odorant receptors are highly homologous,consist of ca. 320 amino acids, and show a heptahelical transmembrane structure as typical for G-protein-coupled receptors. In the human genome, 347 putative full-length olfactory receptor genes have been identified,which allow via characteristic activation patterns of the associated glomeruli the differentiation of more than 10 000 odorants. Since the odorant receptors are built from enantiomerically pure amino acids, they are themselves chiral. Consequently, one would expect a strong diastereomeric interaction, and enantiomeric pairs of odorants should thus differ significantly in both their odor character and their strengths or odor threshold.

  10. Nickel: makes stainless steel strong

    Science.gov (United States)

    Boland, Maeve A.

    2012-01-01

    Nickel is a silvery-white metal that is used mainly to make stainless steel and other alloys stronger and better able to withstand extreme temperatures and corrosive environments. Nickel was first identified as a unique element in 1751 by Baron Axel Fredrik Cronstedt, a Swedish mineralogist and chemist. He originally called the element kupfernickel because it was found in rock that looked like copper (kupfer) ore and because miners thought that "bad spirits" (nickel) in the rock were making it difficult for them to extract copper from it. Approximately 80 percent of the primary (not recycled) nickel consumed in the United States in 2011 was used in alloys, such as stainless steel and superalloys. Because nickel increases an alloy's resistance to corrosion and its ability to withstand extreme temperatures, equipment and parts made of nickel-bearing alloys are often used in harsh environments, such as those in chemical plants, petroleum refineries, jet engines, power generation facilities, and offshore installations. Medical equipment, cookware, and cutlery are often made of stainless steel because it is easy to clean and sterilize. All U.S. circulating coins except the penny are made of alloys that contain nickel. Nickel alloys are increasingly being used in making rechargeable batteries for portable computers, power tools, and hybrid and electric vehicles. Nickel is also plated onto such items as bathroom fixtures to reduce corrosion and provide an attractive finish.

  11. The New Visual Testimonial: Narrative, Authenticity, and Subjectivity in Emerging Commercial Photographic Practice

    2017-03-01

    Full Text Available By studying the cultural and aesthetic impact of increasingly pervasive digital technologies and mass amateurization, this paper examines the ramifications of the networked information economy on professional photographic practice and considers the concomitant implications for the photographic classroom. Using the framework of convergence culture as per the writings of Yochai Benkler, Henry Jenkins, Mark Deuze, and Axel Bruns, the impact of accessible and instantaneous image creation and dispersal are explored. Given the rise of consumer engagement in brand co-creation on social media platforms, we can observe massive changes to professional practice in areas such as aesthetics, and the erosion of previous sustainable business models. Indeed, as traditional notions of “expertise” shift from technological prowess to narrative and disseminative abilities, the effects on commercial practice and photographic education need to be addressed. This paper argues that there are three emerging priorities for commercial image use: narrative ability, authenticity, and subjectivity and suggests initial steps in their pedagogical application. By acknowledging these transformations, this paper explores the idea that students need to harness technique, social media influence, adaptability, subjectivity, and storytelling power in order to better serve emerging image-based needs in commercial spaces.

  13. Social critique and engagement between universalism, anti-authoritarianism and diagnosis of domination

    2016-01-01

    Full Text Available The paper discusses a particular ‘isomorphy’ between two forms of social criticism: the ‘holistic’ theoretical social critique represented by such authors as Jürgen Habermas and Axel Honneth and ‘collective social engagement’ represented by such civic movements as the ‘We Won’t Let Belgrade D(rown’ initiative in contemporary Serbia, which the paper tries to distinguish from more conventional forms of popular protest. This ‘isomorphy’, the paper argues, consists in a tension between three distinct imperatives of the justification of critique - those of normative universalism, epistemological anti-authoritarianism, and diagnosis of social domination - produced by the attempts of both the ‘holistic’ social critics and the collectively engaged actors to simultaneously respond to all three imperatives. After presenting the three types of theoretical critique that crystallize around each imperative, the paper discusses the internal tension that arises in the works of ‘holistic’ theoretical critics and then identifies the same kind of tension in the ‘We Won’t Let Belgrade D(rown’ initiative. The tension in the movement’s critique is outlined through a brief analysis of the activists’ discourse as articulated in the bulletin We Won’t Let Belgrade D(rown issued in March 2015. Since the examples also suggest that collective engagement is better than theoretical critique at keeping this tension ‘productive’, the paper finally offers some tentative thoughts on the possible reasons for this difference.

Para Honneth –quien retoma a Hegel y a Mead–, las primeras relaciones amorosas son sustanciales para vivir el reconocimiento afectivo –que se vive con los más íntimos–; en ellas la aceptación emocional va unida a sentimientos como la simpatía y la atracción, y les permite visibilizar al otro a partir de sus necesidades propias y su valor humano. Abordaremos la familia como primera estructura de acogida y primer escenario de socialización, para argumentar que los niños viven en sus familias, prácticas de reconocimiento de sí mismos, de los otros y del mundo que les rodea, lo cual, a nuestro modo de ver, hace parte de su proceso de socialización como sujetos políticos.

    Full Text Available O objetivo deste artigo é compreender o contexto do trabalho na chamada sociedade da informação e as diferentes formas de trabalho que nela se desenvolvem, em especial o teletrabalho em call centers. Diante de um novo paradigma tecnológico, característico da era da informação, trata-se de analisar as diferentes configurações do trabalho. O trabalho em call centers parece condensar as ambigüidades de um trabalho informacional com alto controle, o que o colocaria entre as esperanças do pós-taylorismo e os temores do neo-taylorismo. A Teoria Crítica de Axel Honneth permite-nos pensar a experiência do trabalho no seio daquilo que o autor intitula "paradoxos do capitalismo". O significado do trabalho, em sua dimensão social, ganha força ao ser demonstrado que o "novo capitalismo" logra produzir progresso moral, baseado nos legados do Estado Social e do modelo taylorista e fordista de trabalho, e, simultaneamente, produz o seu contrário, ao erodir o alcance emancipador dessas normas e valores. Este estudo analisa o trabalho em call centers em três países de língua portuguesa: Brasil, Portugal e Cabo Verde.

    This paper considers the lithospheric rheological structure of the East Qinling orogenic belt to explore its geodynamics. The lithospheric rheological structure was calculated by the constraints of the lithospheric temperature structure. The thermal-rheological stratification structures of the lithosphere in the East Qinling orogenic belt present different features from each other within different tectonic units. The hinterland fault-bounded fold zone (HLZ) and the North Qinling thick-skinned imbricated thrust zone (NQL) in the northern half part of the Qinling orogen, with a tempera-ture of 305℃ for the Moho boundary, are characterized by "cold" geotherm, thickened lithosphere and the model C for rheological stratification structure. The South Qinling tectonic zone (SQL), with a mean temperature of 642℃ and a high temperature of 826℃ for the Moho boundary, has obvious features with the model H of"hot" geotherm, thinned lithosphere and intensive rheological behavior within moderate-lower crust and top of the upper mantle. During post-orogenesis, the NQL, being the convergent frontal region of continental subduction beneath the Qinling orogen by both the North China craton (NC) and Yangtze craton (YZ), is in a coexistence period of a dominantly thickened lithosphere and an initial delamination, and the SQL, proba-bly under pluming, has been developing new delamination and underplating and partial melting within the crust in its axel area and recycling for mass and energy (in the forms of heat transfer and convection) between the crust and mantle.

    The importance of chemosensation for vertebrates is reflected in the vast and variable nature of their chemosensory tissues, neurons, and genes, which we explore in this review. Immense progress has been made in elucidating the molecular biology of olfaction since the discovery of the olfactory receptor genes by Buck and Axel, which eventually won the authors the Nobel Prize. In particular, research linking odor ligands to olfactory receptors (ORs) is truly revolutionizing our understanding of how a large but limited number of chemosensory receptors can allow us to perceive the massive diversity of odors in our habitat. This research is providing insight into the evolution of genomes and providing the raw data needed to explore links between genotype and phenotype, still a grand challenge in biology. Research into olfaction is still developing and will no doubt continue until we have a clear understanding of how all odors are detected and the evolutionary forces that have molded the chemosensory subgenome in vertebrates. This knowledge will not only be a huge step in elucidating olfactory function, advancing scientific knowledge and techniques, but there are also commercial applications for this research. This review focuses on the molecular basis of chemosensation, particularly olfaction, its evolution across vertebrates and the recent molecular advances linking odors to their cognate receptors.

  6. Philosophy and war: Hegel’s therapeutic movement of the spirit

    Full Text Available In addition to Axel Honneth’s thesis on the therapeutic function of the concept of ethical life in Hegel’s philosophy, I want to underline two moments which, to my mind, show Hegel’s views on the therapeutic dimension of both philosophy and the war against the pathology of civil society more clearly. In this context, (a philosophy performs a corrective function by fostering the individual’s virtue conceived as an ethical duty of care both for oneself and for others. The main aim of Hegel’s practical philosophy is hence to return the individual from abstract subjective concepts to his concrete everyday intersubjective practices, and to show him the way to understand himself and the social world as originally related to each other; (b one of the main problems for the moral development of individuals consists in their propensity to perceive the good in particularist and selfish terms: in this context events such as natural disasters or wars can be seen as performing a therapeutic function by teaching individuals to view the good in more principled and general terms.

    2015-01-01

    Full Text Available This paper discusses the convergence between literature and social-political analysis in Axel Honneth’s social philosophy, more precisely in his most recent work. Honneth demonstrates how primarily films and novels can draw attention to social pathologies in the sense pursued in his model of critical theory, thus creating tracks to investigate a particular understanding of a society situated in its time. Thus, this paper starts by focusing on the delineation of what is meant by social pathology and some of its modes in Honneth’s theory of recognition. It then analyzes how Honneth draws on works of art to identify social pathologies and subsequently applies this method of analysis to the Brazilian film “Neighboring sounds”, of director Kleber Mendonça Filho. In the conclusion it returns to the consideration of the mechanism of social pathologies that cause invisibility as impediments to social emancipation and how these barriers can be analyzed from a methodological point of view in consonance with the critical theory.

  8. Glacier volume response time and its links to climate and topography based on a conceptual model of glacier hypsometry

    2009-03-01

    Full Text Available Glacier volume response time is a measure of the time taken for a glacier to adjust its geometry to a climate change. It is currently believed that the volume response time is given approximately by the ratio of glacier thickness to ablation at the glacier terminus. We propose a new conceptual model of glacier hypsometry (area-altitude relation and derive the volume response time where climatic and topographic parameters are separated. The former is expressed by mass balance gradients which we derive from glacier-climate modelling and the latter are quantified with data from the World Glacier Inventory. Aside from the well-known scaling relation between glacier volume and area, we establish a new scaling relation between glacier altitude range and area, and evaluate it for seven regions. The presence of this scaling parameter in our response time formula accounts for the mass balance elevation feedback and leads to longer response times than given by the simple ratio of glacier thickness to ablation. Volume response times range from decades to thousands of years for glaciers in maritime (wet-warm and continental (dry-cold climates, respectively. The combined effect of volume-area and altitude-area scaling relations is such that volume response time can increase with glacier area (Axel Heiberg Island and Svalbard, hardly change (Northern Scandinavia, Southern Norway and the Alps or even get smaller (The Caucasus and New Zealand.

  9. Produsage as a form of self-publication. A qualitative study of casual news produsage

    2011-04-01

    While Axel Bruns's theory of produsage offers an adequate way of looking at a variety of sites where the production of news content takes the form of collaborative, user-driven production, it seems less suited for the study of productive news use as a user experience, as a way users engage in a more productive way with content. This article gives a first impetus towards the expansion of the theory of produsage to a more user-oriented framework that is fitted to approach produsage as a social practice, rather than as a process of information production. The empirical work presented in this paper concerns the average news user, rather than the expert bloggers and citizen journalists most studies tend to focus on. Through a qualitative, semi-experimental study based on a Living Lab-approach, motivational, situational, and social factors shaping productive news use are identified. Drawing from the findings, conceptual elements as "potential public" and "social reflex" are introduced. Self-publication is proposed as a way to understand how average news users experience productive news use.

    Full Text Available Die vorliegende Studie untersucht Gemeinsamkeiten und Unterschiede in der Israel- Berichterstattung der Zeitungen Welt und Jungle World. Trotz ihrer gegensätzlichen Positionierung im politischen Links-Rechts-Spektrum, ist den beiden Medien eine solidarische Haltung gegenüber dem Staat Israel gemeinsam. Damit stehen sie dem Mainstream deutscher Medien entgegen, die laut bestehenden empirischen Untersuchungen eher israelkritisch berichten. Eine einführende Analyse des historischen Hintergrunds verortet das Verhältnis von Deutschland und deutschen Medien zu Israel und beschreibt die Entwicklung der Israel-Solidarität innerhalb der deutschen Linken und der Axel Springer AG. Mittels einer explorativen Clusteranalyse wurden Medien-Frames ermittelt, die sich in Meinungsartikeln der Jungle World und der Welt widerspiegeln. Ein intermedialer Vergleich zur quantitativen Verwendung dieser Frames wurde durch eine qualitative Sprach- und Themenanalyse ergänzt. Im Ergebnis des Forschungsberichts werden Hypothesen abgeleitet, die vielfältige Anknüpfungspunkte für weiterführende Forschung bieten.

  11. Dai Kanak a Marx e ritorno: antropologia della persona e transindividuale - From the Kanak to Marx and back: a transindividual anthropology of the person

    Directory of Open Access Journals (Sweden)

    Carlo Capello

    2013-06-01

    Full Text Available The aim of this article is to show the deep affinity between non-western ideas of the person and antiindividualistic philosophical ideas through a re-reading of some central texts about the anthropology of the person. African concepts of the person, as described by Fortes, Augé and Riesman, have indeed a remarkable consonance with the intersubjective philosophy of Charles Taylor and Axel Honneth. Even more, a significant affinity can be detected between the Melanesian ideas of the person – what Marilyn Strathern called “dividual” – and the notion of transindividual emerging from an anthropological reading of Marx. The common emphasis on social relations as constitutive of the human is the ground permitting the encounter between these two conceptions. The author of this article suggests that the anthropology of the person offers a precious archive of alternative visions of the human reality, which, in dialogue with the idea of transindividuality, could promote the reprise of a Marxist anthropology engaged in the critique of the hegemonic individualism.

  12. Neural relativity principle

    Koulakov, Alexei

    Olfaction is the final frontier of our senses - the one that is still almost completely mysterious to us. Despite extensive genetic and perceptual data, and a strong push to solve the neural coding problem, fundamental questions about the sense of smell remain unresolved. Unlike vision and hearing, where relatively straightforward relationships between stimulus features and neural responses have been foundational to our understanding sensory processing, it has been difficult to quantify the properties of odorant molecules that lead to olfactory percepts. In a sense, we do not have olfactory analogs of ``red'', ``green'' and ``blue''. The seminal work of Linda Buck and Richard Axel identified a diverse family of about 1000 receptor molecules that serve as odorant sensors in the nose. However, the properties of smells that these receptors detect remain a mystery. I will review our current understanding of the molecular properties important to the olfactory system. I will also describe a theory that explains how odorant identity can be preserved despite substantial changes in the odorant concentration.

    2004-12-25

    The 2004 Nobel Prize for Physiology or Medicine has been awarded to Richard Axel and Linda B. Buck, for their discovery of smell receptors and the organisation of the olfactory system. Their original discovery concerned the identification of some 1000 genes that code for smell receptors in the olfactory epithelium of the rat. They also demonstrated that each receptor can only be activated by a limited number of odourants and that there is some overlap in specificity with other smell receptors. Odourants in inhaled air are specifically recognized and bound by the smell receptors on the olfactory neurones in the nasal epithelium. The activated neurones send an electrical signal to the mitral cells, the dendrites of which lie in the glomeruli of the olfactory bulb. In each olfactory neuron only one smell receptor gene is expressed. Neurones with the same type of receptor are spread throughout the epithelium but converge in the same glomerulus. An olfactory map is formed by means of mitral-cell projections which run to the cerebral cortex as well as to other parts of the brain. Possibly the information gained about odourants will be applied in the areas of physiology and pathophysiology; in the field of pharmacology for example where odourants may be used in the treatment of disorders of fertility, behaviour or mood.

Retoma el pensamiento occidental estigmatizante y contrapone a éste el pensamiento moderno que exalta el reconocimiento de lo diverso como forma de inclusión, lo que lo convierte en un discurso amenazante para el proyecto homogenizante europeo. Muestra cómo la tarea de una psicología de la exclusión, es el análisis de las prácticas de borramiento, rechazo y no reconocimiento del otro en lo social, así como sus consecuencias en lo subjetivo y en la identidad, entendiendo el reconocimiento como la aceptación e inclusión de las diferencias en las prácticas sociales. Esto como alusión a lo planteado por Axel Honnet, quien ubica el amor, el derecho y la solidaridad a la base de prácticas inclusivas, en oposición a las formas de menosprecio como el “socavo de la identidad personal en su totalidad”.

    on the spot. When we approached Capri by crossing the Neapolitan bay the first thing our eyes saw was the chapel of San Michele resting high above the blue waters at the top of the steep cliffs - on the edge of the abyss. This place is also the location of the Egyptian Sphinx, half lion, half woman...... swimming hole of the Roman emperor Tiberius, as a “Fairy World”, was also the stupendous home of Axel Munthe. At Villa San Michele, entering through the beautiful loggias and the long row of arcades to the chapel that Munthe also restored, our eyes first felt the enigma of the spirit of the place - we...... wanted to know what happened.

  17. Experimental constraints on the γ-ray strength function in 90Zr using partial cross sections of the Y89(p,γZr90 reaction

    2015-05-01

    Full Text Available Partial cross sections of the Y89(p,γZr90 reaction have been measured to investigate the γ-ray strength function in the neutron–magic nucleus 90Zr. For five proton energies between Ep=3.65 MeV and Ep=4.70 MeV, partial cross sections for the population of seven discrete states in 90Zr have been determined by means of in-beam γ-ray spectroscopy. Since these γ-ray transitions are dominantly of E1 character, the present measurement allows an access to the low-lying dipole strength in 90Zr. A γ-ray strength function based on the experimental data could be extracted, which is used to describe the total and partial cross sections of this reaction by Hauser–Feshbach calculations successfully. Significant differences with respect to previously measured strength functions from photoabsorption data point towards deviations from the Brink–Axel hypothesis relating the photo-excitation and de-excitation strength functions.

    the redetermined 176Lu decay constant of Scherer et al. [6] is correct. Our model of a stable basaltic Hadean shell for the pre-plate tectonic era explicitly refutes operation of processes such as sediment recycling or melting of hydrated material in subduction zones as far back as 4.4 Ga (as recently suggested by [7]; and [8]). Instead, we propose that initiation of terrestrial subduction occurred at ca. 3.75 Ga, at which stage most of the Hadean basaltic shell (and its differentiation products) was recycled into the mantle, because of the lack of a stabilising mantle lithosphere. We further argue that >3.75 Ga terrestrial rocks and minerals were not preserved by chance, but because of creation of a lithospheric mantle keel concommitant with intrusion of voluminous granitoids immediately after establishment of global subduction. In other words, the only portions of >3.75 Ga crust (basaltic and otherwise) that survived were those that were involved in voluminous arc magmatism along the earliest subduction zones.

    Frost action is one of the main causes of deterioration of porous building materials in regions at middle to high latitudes. Damage will occur when the internal stresses due to ice formation become larger than the strength of the material. Hence, the sensitivity of the material to frost damage is partly defined by the structure of the solid body. On the other hand, the size, shape and interconnection of pores manages the water distribution in the building material and, therefore, the characteristics of the pore space control potential to form ice crystals (Ruedrich et al., 2011). In order to assess the damage to building materials by ice crystallization, lot of effort was put into identifying the mechanisms behind the stress build up. First of all, volumetric expansion of 9% (Hirschwald, 1908) during the transition of water to ice should be mentioned. Under natural circumstances, however, water saturation degrees within natural rocks or concrete cannot reach a damaging value. Therefore, linear growth pressure (Scherer, 1999), as well as several mechanisms triggered by water redistribution during freezing (Powers and Helmuth, 1953; Everett, 1961) are more likely responsible for damage due to freezing. Nevertheless, these theories are based on indirect observations and models and, thus, direct evidence that reveals the exact damage mechanism under certain conditions is still lacking. To obtain this proof, in-situ information needs to be acquired while a freezing process is performed. X-ray computed tomography has proven to be of great value in material research. Recent advances at the Ghent University Centre for Tomography (UGCT) have already allowed to dynamically 3D image crack growth in natural rock during freeze-thaw cycles (De Kock et al., 2015). A great potential to evaluate the different stress build-up mechanisms can be found in this imaging technique consequently. It is required to cover a range of materials with different petrophysical properties to achieve

  20. Early Differentiation of the Crust-Mantle System: a Hf Isotope Perspective

    Scherer, E.; Munker, C.; Mezger, K.

    2001-12-01

    The Lu decay constant recently determined by Scherer et al. 2001 (i.e., 1.865 x 10-11 yr-1) agrees with the results of the two latest physical counting experiments (1.86 x 10-11 yr-1; Dalmasso et al 1992, Nir-El and Lavi 1998), but is ca. 4 percent lower than the decay constants that have been used throughout the Hf isotope literature (e.g., 1.94 x 10-11, Tatsumoto et al., 1981; 1.93 x 10-11 Sguigna et al, 1982). In addition to making Lu-Hf ages older by ca. 4 percent, the revised decay constant also shifts the calculated initial epsilon Hf values of early Archean and Hadean rocks and zircons that are used to constrain crust-mantle differentiation in the early Earth. The initial epsilon Hf values for low-Lu/Hf samples such as zircons and evolved felsic rocks shift downward by 2-4 epsilon units, primarily due to the shift in the position of the CHUR evolution curve rather than that of the samples themselves. Mafic rocks, such as komatiites have higher Lu/Hf ratios that are closer to that of CHUR and therefore their initial epsilon Hf values do not shift as much (up to 1.3 epsilon units lower or 0.4 epsilon units higher). Using the old decay constant, some early Archean rocks (e.g., Amitsoq gneisses; Vervoort et al., 1996, Vervoort and Blichert-Toft, 1999) seemed to have very high initial epsilon Hf values (up to +6), implying that the upper mantle was moderately depleted in the early Archean and that a substantial volume of crust was produced in the Hadean. However, when recalculated with the new decay constant, the data suggest that the mantle was only slightly depleted, requiring less early crust extraction, and allowing a later date for the onset of significant crust production. In contrast, the extremely low recalculated epsilon Hf values of Earth's oldest zircons (Amelin et al., 1999, Amelin et al., 2000) indicate that Earth's first crust formed at or before 4.3 Ga, and that this crust remained intact long enough (>200 million years) to evolve to such low

    The physically-based hydrological and soil erosion model CATFLOW-SED has been developed with data from a loess area in Germany (Maurer, 1997; Scherer, 2008) and covers the principal processes detachment, transport and deposition. The catchment is divided into slopes on the basis of topography as well as soil and land-use maps. The slopes are further divided into slope segments and the flow-routing is abstractly modeled as slope cross sections connected by a drainage network. In many process-based soil erosion models, soil erosion is calculated by an interaction of the forces of flowing water and rainfall. In CATFLOW-SED the detachment process is divided into the pulse current of precipitation and the sheer stress of flowing water. The most important parameter concerning detachment is the erosion resistance parameter fcrit. The described model is parameterized for a small catchment in the Central Spanish Pyrenees with experimental field data from this study area. The mean annual precipitation amount of 1120 mm is rather high but as it is typical of a Mediterranean climate the summer months show a deficit in water balance. Accordingly, a seasonal variation in dominating overland flow generation and soil erosion processes, can be observed particularly for wetland areas that regularly dry out in summer. The spatial and temporal pattern of overland-flow generation and erosion processes and their intensity in the study area is assessed by means of small plot-scale rainfall experiments in the field. The gained data are the amounts of overland flow and eroded material for intervals of five minutes duration. The gained results are used for the parameterization of the soil specific parameter fcrit in CATFLOW-SED. In order to cover the seasonal variation in dominating runoff processes, rainfall simulations that were carried out under dry soil moisture conditions in September as well as measurements that were done under moist conditions in March are used for parameterization

    2009-04-01

    Polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) are classes of organic substances with most of the individual substances being semivolatile and to some degree resisting degradation in the environment (persistent), hence, undergo long-range transport and reach pristine areas in high altitudes and latitudes. PCBs and even more so PAHs pose significant human health hazards in Europe (WHO, 2003). PAHs are emitted especially in incomplete combustion processes in both the gaseous and particulate phases (sorbed to soot). PCBs have been banned from most uses, such that re-emission and volatilization from old urban and industrial materials are prevailing atmospheric sources. As a consequence of fuel, combustion technology and legislative changes sources are changing in strength, substance pattern, and geographic distribution. Monitoring data in air at a central European continental background station, Košetice, Czech Republic, of 1997-2007 (Holoubek et al., 2007) were used in combination with back-trajectories to localize sources of selected PAHs and PCBs in central, western, eastern and southeastern Europe. The trajectory scheme uses the isentropic coordinate with some diabatic components and a special boundary layer modelling (Reimer & Scherer, 1992). Areal contact matrices over Europe are obtained by integration in time of the contacts of the backward trajectories with the ground (1x1 km2 grid) and weighting by the observed concentrations (or fictive concentrations of factors). Positive matrix factorization (Paatero, 1997) was used to infer the substance patterns of the sources (so-called factors) which most significantly contributed to PAH levels at Košetice and a second site, Leipzig, Germany. The interpretation of the results is based on matrices of transport to up to three receptor sites in central Europe. Potential source distributions are presented and discussed. The analysis of air pollution in Košetice in the periods 1997-99 and

    The Banting Medal for Scientific Achievement is the highest scientific award of the American Diabetes Association (ADA). Given in memory of Sir Frederick Banting, one of the key investigators in the discovery of insulin, the Banting Medal is awarded annually for scientific excellence, recognizing significant long-term contributions to the understanding, treatment, or prevention of diabetes. Philipp E. Scherer, PhD, of the Touchstone Diabetes Center, The University of Texas Southwestern Medical Center, Dallas, TX, received the prestigious award at the ADA's 75th Scientific Sessions, 5-9 June 2015, in Boston, MA. He presented the Banting Lecture, "The Multifaceted Roles of Adipose Tissue-Therapeutic Targets for Diabetes and Beyond," on Sunday, 7 June 2015.A number of different cell types contribute to the cellular architecture of adipose tissue. Although the adipocyte is functionally making important contributions to systemic metabolic homeostatis, several additional cell types contribute a supportive role to bestow maximal flexibility on the tissue with respect to many biosynthetic and catabolic processes, depending on the metabolic state. These cells include vascular endothelial cells, a host of immune cells, and adipocyte precursor cells and fibroblasts. Combined, these cell types give rise to a tissue with remarkable flexibility with respect to expansion and contraction, while optimizing the ability of the tissue to act as an endocrine organ through the release of many protein factors, critically influencing systemic lipid homeostasis and biochemically contributing many metabolites. Using an example from each of these categories-adiponectin as a key adipokine, sphingolipids as critical mediators of insulin sensitivity, and uridine as an important metabolite contributed by the adipocyte to the systemic pool-I will discuss the emerging genesis of the adipocyte over the past 20 years from metabolic bystander to key driver of metabolic flexibility.

    The European Workshop on Advanced Control and Diagnosis is an annual event that has been organised since 2003 by Control Engineering departments of several European universities in Germany, France, the UK, Poland, Italy, Hungary and Denmark. The overall planning of the workshops is conducted by the Intelligent Control and Diagnosis (ICD) steering committee. This year's ACD workshop took place at HTW Berlin (University of Applied Sciences) and was organised by the Control Engineering group of School of Engineering I of HTW Berlin. 38 papers were presented at ACD 2014, with contributions spanning a variety of fields in modern control science: Discrete control, nonlinear control, model predictive control, system identification, fault diagnosis and fault-tolerant control, control applications, applications of fuzzy logic, as well as modelling and simulation, the latter two forming a basis for all tasks in modern control. Three interesting and high-quality plenary lectures were delivered. The first plenary speaker was Wolfgang Weber from Pepperl+Fuchs, a German manufacturer of state-of-the-art industrial sensors and process interfaces. The second and third plenary speakers were two internationally high-ranked researchers in their respective fields, Prof. Didier Theilliol from Université de Lorraine and Prof. Carsten Scherer from Universität Stuttgart. Taken together, the three plenary lectures sought to contribute to closing the gap between theory and applications. On behalf of the whole ACD 2014 organising committee, we would like to thank all those who submitted papers and participated in the workshop. We hope it was a fruitful and memorable event for all. Together we are looking forward to the next ACD workshop in 2015 in Pilsen, Czech Republic. Horst Schulte (General Chair), Sören Georg (Programme Chair)

    The optical and dielectric properties of Copper Oxide (CuO) have made it a fascinating material to be used in solar energy harvesting, gas sensing, optoelectronics and catalytical applications. Focusing on the cost-effectiveness of Sol-gel method, it is employed for nanostructured CuO production. Effect of changing temperature is observed on the formation mechanism of CuO and its properties. The temperature range of 300 °C–500 °C was used in annealing of samples to produce defect free CuO nanomaterial. Prepared material was investigated using phase characterization (X-ray diffraction ‘XRD’) technique, scanning electron microscopy (SEM), UV–Visible absorption spectroscopy and LCR meter. A structural change in prepared CuO was observed from cluster formation to Nano-fibrils by increase in annealing temperature. 11.99 nm–29.17 nm crystallites of CuO were attained by using Debye Scherer formula. A large band gap of 3.15 eV was achieved by increasing the annealing temperature upto 400 °C. For better solar energy harvest, wide band gapped CuO structures are proved to be functional and practical materials. The fabricated CuO nanostructures were found suitable to be used in devices for stabilizing circuit designs for sensitive appliances as well as micro electromechanical systems (mems). - Highlights: • CuO was synthesized by using sol gel method post growth annealing process. • XRD and SEM characterizations confirm the successful synthesis of CuO. • Change in morphology was observed with varying annealing temperature. • Improved optical and dielectric properties were observed.

    The study of aerosol exposure and dosimetry measurements and related quantitation of health effects are important to the understanding of the consequences of air pollution, and are discussed widely in the scientific literature. During the last 10 years the need to correlate aerosol exposure and biological effects has become especially important due to rapid development of a new, revolutionary industry ?-- nanotechnology. Nanoproduct commerce is predicted to top $1 trillion by 2015. Quantitative assessment of aerosol particle behavior in air and in lung deposition, and dosimetry in different parts of the lung, particularly for nanoaerosols, remains poor despite several decades of study. Direct measurements on humans are still needed in order to validate the hollow cast, animal studies, and lung deposition modeling. We discuss here the use of nanoscale radon decay products as an experimental tool in the study of local deposition and lung dosimetry for nanoaerosols. The issue of the safe use of radon progeny in such measurements is discussed based on a comparison of measured exposure in 3 settings: general population, miners, and in a human experiment conducted at the Paul Scherer Institute (PSI) in Switzerland. One of the properties of radon progeny is that they consist partly of 1 nm radioactive particles called unattached activity; having extremely small size and high diffusion coefficients, these particles can be potentially useful as radioactive tracers in the study of nanometer-sized aerosols. We present a theoretical and experimental study of the correlation between the unattached activity and aerosol particle surface area, together with a description of its calibration and method for measurement of the unattached fraction.

    Wellbore integrity is essential to ensuring long-term isolation of buoyant supercritical CO{sub 2} during geologic sequestration of CO{sub 2}. In this report, we summarize recent progress in numerical simulations of cement-brine-CO{sub 2} interactions with respect to migration of CO{sub 2} outside of casing. Using typical values for the hydrologic properties of cement, caprock (shale) and reservoir materials, we show that the capillary properties of good quality cement will prevent flow of CO{sub 2} into and through cement. Rather, CO{sub 2}, if present, is likely to be confined to the casing-cement or cement-formation interfaces. CO{sub 2} does react with the cement by diffusion from the interface into the cement, in which case it produces distinct carbonation fronts within the cement. This is consistent with observations of cement performance at the CO{sub 2}-enhanced oil recovery SACROC Unit in West Texas (Carey et al. 2007). For poor quality cement, flow through cement may occur and would produce a pattern of uniform carbonation without reaction fronts. We also consider an alternative explanation for cement carbonation reactions as due to CO{sub 2} derived from caprock. We show that carbonation reactions in cement are limited to surficial reactions when CO{sub 2} pressure is low (< 10 bars) as might be expected in many caprock environments. For the case of caprock overlying natural CO{sub 2} reservoirs for millions of years, we consider Scherer and Huet's (2009) hypothesis of diffusive steady-state between CO{sub 2} in the reservoir and in the caprock. We find that in this case, the aqueous CO{sub 2} concentration would differ little from the reservoir and would be expected to produce carbonation reaction fronts in cements that are relatively uniform as a function of depth.

    Nanocrystalline Yb3+ doped Gd2O3 phosphors were synthesized by solid state reaction method (SSRM), and effect of Yb3+ concentrations (1 mol% to 7 mol%) on thermoluminescence properties were studied. The XRD technique shows the cubic structure of prepared phosphor for different concentrations of Yb3+. No phase change was found due to the dopant concentration. The crystal size was calculated by Scherer's formula, which is found in 20-60 nm range. The same was also confirmed from the field emission gun scanning electron microscopy (FEGSEM) image, which shows the formation of nanospheres having diameter 20-60 nm range. They are found to be quite uniform in shapes and sizes. Functional group analysis was studied by Fourier transform infrared spectroscopy (FTIR) techniques and the elemental analysis of prepared phosphor was studied by energy dispersive X-ray spectroscopic (EDX) analysis. The samples were irradiated with UV and gamma radiation for the doses varying from 5 to 30 min for UV and 0.5 kGy to 2 kGy for gamma respectively and their thermoluminescence (TL) characteristics have been studied. The effect of heating rate (3-7 °C s-1) and effect of Yb3+ concentration in TL glow curve have been studied. The TL glow curve of nanophosphor shows a peak at around 130 °C for UV and at 247 °C for gamma irradiation respectively. The TL response of the sample irradiated with different gamma doses shows a linear behaviour from 0.5 kGy to 2 kGy and become sublinear behaviour in the range of 5-25 min UV exposure before it saturates with further increase in the dose. Simple glow curve structure, easy method of synthesis and the linear dose response make the nanocrystalline phosphor a good candidate for radiation dosimetry, especially for the estimation of high doses of gamma rays where the nanocrystalline phosphors generally saturated.

The role of extracellular cations is usually perceived to be the source for intracellular cations in the process of homeostasis. The role of surface molecules that interact with extracellular cations is believed to be that of channels, transporters, and exchangers. However, the role of Ca2+ as a signal and chemoattractant and the discovery of the Ca2+ receptor have demonstrated that extracellular cations can function as signals at the cell surface, and the plasma membrane molecules they interact with can function as bona fide receptors that activate coupled signal transduction pathways, associated molecules in the plasma membrane, or the cytoskeleton. With this perspective in mind, we have reviewed the cationic composition of aqueous environments of free living cells and cells that move in multicellular organisms, most notably humans, the range of molecules interacting with cations at the cell surface, the concept of a cell surface cation receptor, and the roles extracellular cations and plasma membrane proteins that interact with them play in the regulation of motility, shape, and chemotaxis. Hopefully, the perspective of this review will increase awareness of the roles extracellular cations play and the possibility that many of the plasma membrane proteins that interact with them could also play roles as receptors.Keywords: extracellular cations, chemotaxis, transporters, calcium, receptors

    We present and discuss the gas-phase electronic absorption spectra of selected ionized polycyclic aromatic hydrocarbons (PAHs) measured in the UV-Visible-NIR range in an astrophysically relevant environment. This type of measurements provides data on PAHs and nanometer-sized particles that can now be directly compared to astronomical spectra of the UV interstellar (IS) extinction curve and of the diffuse interstellar bands (DIBs). The harsh physical conditions of the IS medium - characterized by a low temperature, an absence of collisions and strong VUV radiation fields - are simulated in the laboratory by associating a molecular beam with an ionizing discharge to generate a cold plasma expansion. This source combines a pulsed slit supersonic free jet expansion of argon seeded with PAHs (Salama, F., Allamandola, L. J. & Scherer, J. J., `Pulsed discharge nozzle cavity ringdown spectroscopy of cold PAH ions', J. Chem Phys.;in press) that have been pre-selected from Matrix Isolation Spectroscopy (MIS) studies. The absorption spectrum of the Pyrene cation (C16H10+) has also been measured. These experiments provide unique information on the spectra of free, large carbon-containing molecules and ions in the gas phase. The electronic bands measured for this selection of PAH ions are all found to be intrinsically broad (>˜20 cm-1). The laboratory data are compared with recent astronomical spectra of large DIBs. Preliminary results also show that carbon nanoparticles (˜2 nm size) are formed during the short residence time of the precursors in the plasma. This finding holds great potential for the spectroscopy of nanoparticles isolated in the gas-phase in an interstellar-like environment and for understanding the formation process of interstellar grains.

    Nickel zinc ferrite nanoparticles with diameters less than 20 nm were synthesized by co-precipitation method. The synthesized nanoparticles were annealed at 500 °C. Two types of samples (powder and disk) were prepared. The disk sample was prepared by pressing the powder sample. Magnetic and structural properties of the products were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and alternating gradient-force magnetometer (AGFM). The X-ray analysis shows that the formation of the synthesized nickel zinc ferrite is spinell. The average crystalline size for nickel zinc ferrite powder was found around 19 nm (calculated by Debye-Scherer formula).The formation, size and the uniformity of the samples were determined by TEM. It was found that the size of nanoparticles should be around 18 nm from the SEM image. AGFM diagrams shows that the magnetization of the powder sample at the 9 kOe is 21.5 emu/g that of disk sample is 33 emu/g. Therefore, the magnetization was increased by pressing the nickel zinc ferrite nanoparticles. Sensor sensitivity of this disk ferrite is investigated in an isolated box. For this purpose, the samples are injected to this box and six gases (ethanol, methanol, chloroform, acetonitrile, acetone and methane) are exposed to the ferrite by a mechanical gate. The acetonitrile had the best sensitivity performance. - Highlights: • Powder and disk nickel zinc ferrite nanoparticles with diameters less than 20 nm were prepared. • Sensor sensitivity of six different gases was tested in an isolated box and acetonitrile had the best sensitivity performance. • The maximum sensor sensitivity was maximum at 350 °C for all tested gases except chloroform. • At 200 ppm concentration, the sensor capacity is reached to the saturation state.

    An inorganic nanomaterials combination of Sm, Ag, and TiO2 was synthesized using supercritical fluid drying (SCFD) combined with sol-gel techniques. The structure, photocatalysis and bacteriostatic activity of the materials were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XRPS), photocatalytic performance, and antibacterial activity experiments. The XRD results showed that the average particle diameter of Sm/Ag/TiO2 was 14.62 nm and Ag and Sm ions were dispersed on the surface of TiO2 in a highly dispersed, amorphous form. The TEM im-age showed that the size of the particle was 12 nm using the scherer formula. The XPS result showed that the element Sm was doped and Ag was loaded inorganic nanomaterials successfully. Sm/Ag/TiO2 exhibited optimal photocatalytic properties at 600 ºC, the photocatalytic optimal proportion of Sm/Ag/TiO2 was 2:2:100. When the molar ratio was 2:2:100, the bacteriostatic cir-cle diameter was 16 mm for Staphylococcus aureus, the minimum bacteriostatic concentration was 200μg/mL for white beads coccus, and the minimum bactericidal concentration was 2×104μg/mL for white beads coccus. The SEM results showed that the antibacterial material attached to the candida albicans cell surface, cells appeared fold deformation. Therefore the inorganic nanomaterials Sm/Ag/TiO2 had high temperature resistance, good photocatalytic and antibacterial characteristics in visible light.

    Pure and Mg{sup 2+} doped ZnO nanoparticles are synthesized by solution combustion method. X-ray diffraction studies of the samples confirm hexagonal phase. Crystallite size is calculated using Scherer formula and found to be ∼30 nm for undoped ZnO and 34–38 nm for Mg{sup 2+} doped ZnO. A broad PL emission in the range 400–600 nm with peaks at 400, 450, 468, 483, 492, 517, 553 nm are observed in both pure and Mg{sup 2+} doped nanoparticles. Near band edge emission of ZnO is observed at 400 nm. The broad band emissions are due to surface defects. PL emission intensity is found to increase with Mg{sup 2+} concentration up to 1.5 mol% and then decreases due to concentration quenching. Samples are irradiated with γ-rays in a dose range 0.05–8 kGy. Gamma irradiation doesn’t affect PL properties. Undoped samples exhibit unstructured low intense TL glow with peak at 720 K. Whereas Mg{sup 2+} doped samples exhibit well structured TL glow curves with peak at ∼618 K. TL glow peak intensity of Mg{sup 2+} doped samples increases with Mg{sup 2+} concentration up to 2 mol%, thereafter decreases. TL curves of Mg{sup 2+} (2 mol%) doped ZnO exhibit two glows, a high intense peak at 618 K and a weak one with peak at ∼485 K. TL intensity of Mg{sup 2+} (2 mol%) doped ZnO samples increases with gamma dose up to 1 kGy and then decreases. Kinetic parameters of TL glows are calculated by deconvolution technique. Activation energy and frequency factor are found to be 1.5 eV and 3.38 × 10{sup 11} s{sup −1} respectively.

    Scherer's Component Process Model provides a theoretical framework for research on the production mechanism of emotion and facial emotional expression. The model predicts that appraisal results drive facial expressions, which unfold sequentially and cumulatively over time. In two experiments, we examined facial muscle activity changes (via facial electromyography recordings over the corrugator, cheek, and frontalis regions) in response to events in a gambling task. These events were experimentally manipulated feedback stimuli which presented simultaneous information directly affecting goal conduciveness (gambling outcome: win, loss, or break-even) and power appraisals (Experiment 1 and 2), as well as control appraisal (Experiment 2). We repeatedly found main effects of goal conduciveness (starting ~600 ms), and power appraisals (starting ~800 ms after feedback onset). Control appraisal main effects were inconclusive. Interaction effects of goal conduciveness and power appraisals were obtained in both experiments (Experiment 1: over the corrugator and cheek regions; Experiment 2: over the frontalis region) suggesting amplified goal conduciveness effects when power was high in contrast to invariant goal conduciveness effects when power was low. Also an interaction of goal conduciveness and control appraisals was found over the cheek region, showing differential goal conduciveness effects when control was high and invariant effects when control was low. These interaction effects suggest that the appraisal of having sufficient control or power affects facial responses towards gambling outcomes. The result pattern suggests that corrugator and frontalis regions are primarily related to cognitive operations that process motivational pertinence, whereas the cheek region would be more influenced by coping implications. Our results provide first evidence demonstrating that cognitive-evaluative mechanisms related to goal conduciveness, control, and power appraisals affect

    The ability to accurately interpret others' emotional expressions in the face, voice, and body is a crucial component of successful social functioning and has been shown to predict better outcomes in private and professional life. To date, emotion recognition ability (ERA) has mostly been measured with tests that heavily rely on static pictures of the face and on few emotions, restricting their content validity. Recently, Schlegel, Grandjean, and Scherer (Psychological Assessment, 26, 666-672, 2014) published a new test that measures ERA in a more comprehensive fashion, by (1) including a wide range of 14 positive and negative emotions and (2) using video clips with sound that simultaneously present facial, vocal, and bodily emotional cues. This article introduces the short version of the Geneva Emotion Recognition Test (the GERT-S), and presents two studies (total N = 425) that examine the internal consistency, factor structure, and convergent and discriminant validity of the test. The results show that the GERT-S is a unidimensional test with good internal consistency. Furthermore, the GERT-S was substantially positively correlated with other ERA tests, with tests of emotional understanding and emotion management, and with cognitive ability. Taken together, the present studies demonstrate the usefulness of the GERT-S as an instrument for the brief and reliable assessment of ERA. It is available, free of charge and in seven different languages, for academic research use. Given the brief test-taking time (approx. 10 min) and its possible administration via different online platforms, the GERT-S can easily be integrated by researchers into their own studies.

    A series of single phase and nanostructured Cr-Ga substituted M-type hexaferrites BaCr{sub x}Ga{sub x}Fe{sub 12-2x}O{sub 19} (x = 0.0-0.4) were synthesized by sol-gel auto-combustion route. The powder samples were pressed into pellets of diameter 12 mm using an excellent technique Cold Isostatic Pressing (CIP) at a pressure of 2000 bar for higher densification. The powdered samples were sintered at 1000 Degree-Sign C for 2 h and characterized by different experimental techniques such as differential scanning calorimetry (DSC), thermogravimetry (TG), Fourier transform infrared spectroscopy (FTIR), X-ray diffractions (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDXS) and vibrating sample magnetometry (VSM) magnetometry analyses. DSC-TG analysis was carried out to observe the transformation of different phases during heat treatment. X-ray diffraction (XRD) confirmed the formation of single phase M-type hexagonal ferrites. The crystallite size calculated by the Scherer equation was found to be in the range of 30-48 nm, which is small enough to obtain a suitable signal-to-noise ratio in the high density recording media. The saturation magnetization and retentivity were observed to increase from 2.078 Multiplication-Sign 10{sup 3} to 2.385 Multiplication-Sign 10{sup 3} Gauss and 1.286 Multiplication-Sign 10{sup 3} to 1.677 Multiplication-Sign 10{sup 3} Gauss, respectively. The coercivity (iH{sub c} and bH{sub c}) enhanced which is attributed to increase in the magnetocrystalline anisotropy. The high values of retentivity and coercivity make these materials best candidate for high density recording media and permanent magnets.

    The semiconducting polycrystalline ferrite materials with the general formula Ni1-x Mg x Fe2O4 were synthesized by using the solid state reaction method. X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectrographs, and atomic force microscopy techniques were utilized to study the structural parameters. XRD confirms the formation of single phase cubic spinel structure of the ferrites. The crystallite sizes of ferrites determined using the Debye-Scherer formula ranges from 0.963 μm to 1.069 μm. The cation distribution of ferrite shows that Mg2+ ions occupy a tetrahedral site (A-site) and the Ni2+ ion occupy an octahedral site (B-site) whereas Fe3+ ions occupies an octahedral as well as a tetrahedral site. The study of elastic parameters such as the longitudinal modulus, rigidity modulus, Young's modulus, bulk modulus, and Debye temperature were estimated using the FTIR technique. The decrease of direct current (DC) resistivity with increase in temperature indicates the semiconducting nature of ferrites. The dielectric constant as well as loss tangent decreases with increase in frequency, and at still higher frequencies, they are almost constant. This shows usual dielectric dispersion behavior attributed to the Maxwell-Wagner type of interfacial polarization and is in accordance with Koop's phenomenological theory. The linear increase of alternating current conductivity with increase of frequency shows the small polaron hopping type of conduction mechanism in all the ferrites. The magnetic properties such as saturation magnetization (M s ), magnetic moment, coercivity, remnant magnetization (M r ), and the ratio of M r /M s was estimated using the M-H loop.

    Hydroxyl (OH) radicals in the atmosphere provide one of the main chemical mechanisms for the removal of trace gases. OH plays a central role in determining the atmospheric lifetime and radiative forcing of greenhouse gases like methane. OH also plays a major role in the oxidation of organic trace gases, which can lead to formation of secondary pollutants such as ozone and PM2.5. Due to its very short atmospheric lifetime of seconds or less, OH concentrations are extremely variable in space and time, which makes measurements and their interpretation very challenging. Several recent measurements have yielded higher than expected OH concentrations. To explain these would require the existence of unidentified, radical recycling processes, but issues with the measurements themselves are also still being discussed. During the NOAA airborne SENEX study in the Southeast U.S., the biogenic hydrocarbons isoprene and monoterpenes were consistently found to have lower mixing ratios in air masses with enhanced nitrogen oxides from power plants. We attribute this to faster oxidation rates of biogenic hydrocarbons due to increased concentrations of OH in the power plant plumes. Measurements at different downwind distances from the Scherer and Harllee Branch coal-fired power plants near Atlanta are used to constrain the dependence of OH on nitrogen oxides. It is found that OH concentrations were highest at nitrogen dioxide concentrations of 1-2 ppbv and decreased at higher and at lower concentrations. These findings agree with the expected dependence of OH on nitrogen oxide concentrations, but do not appear to be consistent with the reports in the literature that have shown high OH concentrations in regions of the atmosphere with high biogenic emissions and low NOx concentrations that would require unidentified radical recycling processes to be explained.

    The nanocomposites of the polyaniline and Co{sub 1−x}Cu{sub x}Fe{sub 2}O{sub 4} (PANI/CoCuFe) were prepared by in-situ oxidative polymerization of aniline. Prepared nanocomposites samples were characterized by using various experimental techniques like X-ray diffraction (XRD), Fourier transformed infrared spectroscopy (FT-IR), field emission scanning electron microscope (FE-SEM), vibrating sample magnetometer (VSM), Mössbauer spectroscopy and ultraviolet–visible spectrophotometry (UV–VIS). The elemental analysis as obtained from the energy dispersive X-ray spectroscopy (EDAX) measurement is in close agreement with the expected composition from the stoichiometry of the reactant solutions. XRD result confirms that all the samples have the single phase cubic spinel structure. Unit cell parameter ‘a’ is found to decrease with the increase in copper ion substitution. The crystallite size was investigated by using the Debye–Scherer formula and it was found in the range of ∼28–37 nm. FE-SEM confirmed the homogeneous and well defined surface morphology of the synthesized samples. FT-IR study showed the main absorption bands corresponding to the spinel structure those arose due to the tetrahedral and octahedral stretching vibrations. Cation distribution was estimated using XRD data. Hysteresis measurements revealed that the saturation magnetization decreased with increase in Cu{sup 2+} substitution. Magnetic environment of {sup 57}Fe in Cu-doped cobalt ferrite was investigated by using Mössbauer spectroscopy. Mössbauer study evidenced the ferrimagnetic behavior of the synthesized samples. - Highlights: • Crystallite size decreases with increasing Cu{sup 2+} substitution. • The prepared samples show the formation of single phase cubic spinel structure. • Cation distribution shows that Cu and Co ions shows strong preference toward octahedral B site. • Magnetization decreases with increasing Cu{sup 2+} substitution. • Mössbauer study shows

    The European Space Agency's Rosetta spacecraft (Glassmeier et al., 2007) has been in orbit of the comet 67P/Churyumov-Gerasimenko (67P/C-G) since August 2014. On board is the Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) instrument suite (Balsiger et al., 2007). ROSINA consists of two mass spectrometers, the Double Focusing Mass Spectrometer (DFMS) and the Reflectron-type Time-Of-Flight (RTOF) (Scherer et al., 2006), as well as the COmet Pressure Sensor (COPS). ROSINA is designed to detect and monitor the neutral gas and thermal plasma environment in the comet's coma by in situ investigation. The two mass spectrometers have high dynamic ranges and complement each other with high mass resolution (DFMS) and high time resolution and large mass range (RTOF). Especially the unprecedented sensitivity and mass resolution of DFMS together with the large mass range of RTOF allow determining precisely light species (e.g. isotopologues) as well as detecting heavy organic species. The pressure sensor COPS measures total gas densities, bulk velocities, and gas temperatures. ROSINA has been collecting data on the composition of the coma and activity of the comet from 3.5 AU to pericentre and out again to 3.5 AU. The Rosetta mission presents a unique opportunity to directly sample the parent species in the thin cometary atmosphere of a Kuiper-belt object at distances in excess of 2.5 AU from the Sun all the way to the pericentre of the cometary orbit at 1.24 AU. The ROSINA experiment continuously measured the chemical composition of the gases in the cometary coma. Occasionally, a dust grain of cometary origin enters the ion source of a ROSINA instrument where the volatile part evaporates since these ion sources are hot. We will report on the first measurements of the volatile inventory of such dust grains. Volatile release from cometary dust grains was observed with all three ROSINA instruments on several occasions. Because the volatile content of such a dust

Una de las opciones analizadas se vincula con el filósofo frankfurtiano Axel Honneth, quien ha desarrollado un conjunto de tesis acerca de la relevancia del reconocimiento recíproco en relación a las dinámicas que movilizan los conflictos sociales. Además de la necesidad de contrastar este planteo con otros enfoques contemporáneos, se revisan algunos supuestos y alcances de la teoría del reconocimiento desde una perspectiva crítica que se contextualiza en el marco de las transformaciones producidas con la globalización y la crisis reciente que atraviesan las sociedades capitalistas. Desde este punto de vista, interesa indagar sobre la significación de las manifestaciones alternativas de los movimientos sociales en sus formas novedosas de protesta y reclamo de justicia.

    Global climate models predict that over the coming century increasing Arctic temperature will lead to increases in the release of greenhouse gases, CO2 and CH4, from thawing the permafrost, which is a major repository of soil carbon. The magnitude and rate of this positive feedback is highly uncertain due to lack of detailed field observations and long-term experimental simulations. To this end long-term core thawing experiments are being carried out to examine gas flux from the Arctic active layer and permafrost under various environmental conditions. Eighteen 1-m long cores were collected before seasonal thaw from a sparsely vegetated, ice-wedge polygon at the McGill Arctic Research Station (MARS) at Axel Heiberg Island, Nunavut, Canada (N79°24, W90°45). The cores contained ~5% organic carbon in the top 15 cm and decreased to ~1% for the remainder of the core, with a solid phase organic carbon δ13C of -26.5‰. The cores were progressively thawed from the top down to the permafrost table over six weeks and held at 4° C under the following conditions: maintenance of an in situ permafrost table depth at 70 cm below surface versus fully thawed permafrost layer, in situ water saturation conditions versus fully water saturated conditions using artificial rain fall, and surface light versus no surface light. Core headspaces were monitored on a weekly basis for concentration of CO2, CH4, and δ13C-CO2. Over the thawing period, the CH4 flux out of the soil decreased from the initial rate of 2.2 μmol CH4/m2/day to 0.12 μmol CH4/m2/day, indicating that CH4 trapped in the soil outgassed as temperatures rose above freezing but the flux rapidly diminished. Introduction of 2 PPMV CH4 into the headspace of under-saturated core treatments revealed net depletion of CH4 was taking place at -3.6 μmol CH4/m2/day, an observation consistent with field measurements of methanotrophy at Axel Heiberg Island during spring and summer and with laboratory microcosm experiments

    scientific history, but also crucial information on how governmental sponsorship, from the 1860s till the end of WW II, modulated the development of solar research. This paper reveals lots of cross-references on scientists and government agents, and also offers insight on the interplay between political actors and scientific researchers. The last paper covers very dense time lines, and also vividly illustrates the military value of basic fundamental research - that is, the forecast of radio propagation disturbances caused by solar flares. This element is also dealt with in the subsequent paper by Hubertus Wohl, on the spectroheliogram archives of the Fraunhofer (now Kiepenheuer) Institute. Accounts of pioneering episodes are given in Axel Wittmann's paper on site testing at La Palma in the early seventies, as well as in the subsequent paper on solar research with stratospheric balloons (by Manuel Vazquez and Axel Wittmann). These authors sketch a very concise but detailed history of civil ballooning, and illustrate this with several images from private archives. Alltogether, this book is well-edited, and offers lots of historical facts for the money.

  8. Level Densities and Radiative Strength Functions in 56FE and 57FE

    Understanding nuclear level densities and radiative strength functions is important for pure and applied nuclear physics. Recently, the Oslo Cyclotron Group has developed an experimental method to extract level densities and radiative strength functions simultaneously from the primary γ rays after a light-ion reaction. A primary γ-ray spectrum represents the γ-decay probability distribution. The Oslo method is based on the Axel-Brink hypothesis, according to which the primary γ-ray spectrum is proportional to the product of the level density at the final energy and the radiative strength function. The level density and the radiative strength function are fit to the experimental primary γ-ray spectra, and then normalized to known data. The method works well for heavy nuclei. The present measurements extend the Oslo method to the lighter mass nuclei 56Fe and 57Fe. The experimental level densities in 56Fe and 57Fe reveal step structure. This step structure is a signature for nucleon pair breaking. The predicted pairing gap parameter is in good agreement with the step corresponding to the first pair breaking. Thermodynamic quantities for 56Fe and 57Fe are derived within the microcanonical and canonical ensembles using the experimental level densities. Energy-temperature relations are considered using caloric curves and probability density functions. The differences between the thermodynamics of small and large systems are emphasized. The experimental heat capacities are compared with the recent theoretical calculations obtained in the Shell Model Monte Carlo method. Radiative strength functions in 56Fe and 57Fe have surprisingly high values at low γ-ray energies. This behavior has not been observed for heavy nuclei, but has been observed in other light- and medium-mass nuclei. The origin of this low γ-ray energy effect remains unknown.

    Previous studies investigating organic-rich tundra have reported that increasing biodegradation of Arctic tundra soil organic carbon (SOC) under warming climate regimes will cause increasing CO2 and CH4 emissions. Organic-poor, mineral cryosols, which comprise 87% of Arctic tundra, are not as well characterized. This study examined biogeochemical processes of 1 m long intact mineral cryosol cores (1-6% SOC) collected in the Canadian high Arctic. Vertical profiles of gaseous and aqueous chemistry and microbial composition were related to surface CO2 and CH4 fluxes during a simulated spring/summer thaw under light versus dark and in situ versus water saturated treatments. CO2 fluxes attained 0.8 ± 0.4 mmol CO2 m-2 h-1 for in situ treatments, of which 85 ± 11% was produced by aerobic SOC oxidation, consistent with field observations and metagenomic analyses indicating aerobic heterotrophs were the dominant phylotypes. The Q10 values of CO2 emissions ranged from 2 to 4 over the course of thawing. CH4 degassing occurred during initial thaw; however, all cores were CH4 sinks at atmospheric concentration CH4. Atmospheric CH4 uptake rates ranged from -126 ± 77 to -207 ± 7 nmol CH4 m-2 h-1 with CH4 consumed between 0 and 35 cm depth. Metagenomic and gas chemistry analyses revealed that high-affinity Type II methanotrophic sequence abundance and activity were highest between 0 and 35 cm depth. Microbial sulfate reduction dominated the anaerobic processes, outcompeting methanogenesis for H2 and acetate. Fluxes, microbial community composition, and biogeochemical rates indicate that mineral cryosols of Axel Heiberg Island act as net CO2 sources and atmospheric CH4 sinks during summertime thaw under both in situ and water saturated states.

    Full Text Available O texto coloca a questão das condições de possibilidade da intersubjetividade na teoria do reconhecimento. Uma análise da teoria do reconhecimento formulada por Axel Honneth mostra como o conflito determinado por motivações morais relativiza o postulado Habermasiano do entendimento lingüístico e traz de volta a dimensão normativa à teoria social. O autor faz faz um retorno às páginas da Enciclopédia de Hegel para recuperar a dimensão objetiva da intersubjetividade e destacar problemas teóricos no projeto de Honneth. Com isso passa a confrontar tanto o paradigma lingüístico-hermenêutico como o de reconhecimento com o fato de pressuporem a intersubjetividade a ser ainda constituída, para concluir que a teoria do reconhecimento não consegue explicitar um núcleo normativo do reconhecimento intersubjetivo; ela descreve contextos de interação e não imperativos morais. A da regra de ouro, em especial na formulação negativa ("não faças a ninguém aquilo que não gostarias que fosse feito a ti -Tb 4,15 é vista como melhor codificação da exigência de reconhecimento sem prescindir da experiência da ofensa e da luta, como melhor justificação positiva das normas de reciprocidade

    Many intriguing science discoveries on planetary surfaces, such as the seasonal flows on crater walls and skylight entrances to lava tubes, are at sites that are currently inaccessible to state-of-the-art rovers. The in situ exploration of such sites is likely to require a tethered platform both for mechanical support and for providing power and communication. Mother/daughter architectures have been investigated where a mother deploys a tethered daughter into extreme terrains. Deploying and retracting a tethered daughter requires undocking and re-docking of the daughter to the mother, with the latter being the challenging part. In this paper, we describe a vision-based tether-assisted algorithm for the autonomous re-docking of a daughter to its mother following an extreme terrain excursion. The algorithm uses fiducials mounted on the mother to improve the reliability and accuracy of estimating the pose of the mother relative to the daughter. The tether that is anchored by the mother helps the docking process and increases the system's tolerance to pose uncertainties by mechanically aligning the mating parts in the final docking phase. A preliminary version of the algorithm was developed and field-tested on the Axel rover in the JPL Mars Yard. The algorithm achieved an 80% success rate in 40 experiments in both firm and loose soils and starting from up to 6 m away at up to 40 deg radial angle and 20 deg relative heading. The algorithm does not rely on an initial estimate of the relative pose. The preliminary results are promising and help retire the risk associated with the autonomous docking process enabling consideration in future martian and lunar missions.

    The perennial springs at Gypsum Hill (GH) and Colour Peak (CP), situated at nearly 80 degrees N on Axel Heiberg Island in the Canadian high Arctic, are one of the few known examples of cold springs in thick permafrost on Earth. The springs emanate from deep saline aquifers and discharge cold anoxic brines rich in both sulfide and sulfate. Grey-coloured microbial streamers form during the winter months in snow-covered regions of the GH spring run-off channels (-1.3 degrees C to 6.9 degrees C, approximately 7.5% NaCl, 0-20 p.p.m. dissolved sulfide, 1 p.p.m. dissolved oxygen) but disappear during the Arctic summer. Culture- and molecular-based analyses of the 16S rRNA gene (FISH, DGGE and clone libraries) indicated that the streamers were uniquely dominated by chemolithoautotrophic sulfur-oxidizing Thiomicrospira species. The streamers oxidized both sulfide and thiosulfate and fixed CO(2) under in situ conditions and a Thiomicrospira strain isolated from the streamers also actively oxidized sulfide and thiosulfate and fixed CO(2) under cold, saline conditions. Overall, the snow-covered spring channels appear to represent a unique polar saline microhabitat that protects and allows Thiomicrospira streamers to form and flourish via chemolithoautrophic, phototrophic-independent metabolism in a high Arctic winter environment characterized by air temperatures commonly below -40 degrees C and with an annual average air temperature of -15 degrees C. These results broaden our knowledge of the physical and chemical boundaries that define life on Earth and have astrobiological implications for the possibility of life existing under similar Martian conditions.

Firstly, it compares their distinct methodological suppositions, relating them to the current debate over the contradiction between 'moral' and 'ethical' viewpoints. Next, it explores the idea that social struggles for recognition can form a theoretically productive medium for understanding the evolution of political institutions in the modern western world. Finally it examines the role played by the rule of law in modern societies, looking to determine to what point we can adhere to the Habermasian theory of discourse and where this can be usefully complemented by a theory of social recognition.

    Full Text Available Abstract Background Mental health and psychosocial wellbeing are key concerns in displaced populations. Despite urban refugees constituting more than half of the world's refugees, minimal attention has been paid to their psychosocial wellbeing. The purpose of this study was to assess coping behaviour and aspects of resilience amongst refugees in Kathmandu, Nepal. Methods This study examined the experiences of 16 Pakistani and 8 Somali urban refugees in Kathmandu, Nepal through in-depth individual interviews, focus groups, and Photovoice methodology. Such qualitative approaches enabled us to broadly discuss themes such as personal experiences of being a refugee in Kathmandu, perceived causes of psychosocial distress, and strategies and resources for coping. Thematic network analysis was used in this study to systematically interpret and code the data. Results Our findings highlight that urban refugees' active coping efforts, notwithstanding significant adversity and resulting distress, are most frequently through primary relationships. Informed by Axel Honneth's theory on the struggle for recognition, findings suggest that coping is a function beyond the individual and involves the ability to negotiate recognition. This negotiation involves not only primary relationships, but also the legal order and other social networks such as family and friends. Honneth's work was used because of its emphasis on the importance of legal recognition and larger structural factors in facilitating daily coping. Conclusions Understanding how urban refugees cope by negotiating access to various forms of recognition in the absence of legal-recognition will enable organisations working with them to leverage such strengths and develop relevant programmes. In particular, building on these existing resources will lead to culturally compelling and sustainable care for these populations.

In his theory,he regards“family”,”society”and“community”as his theoretical frame,“recognition”as his main thread,“struggle”as his driving force,and connects the human subject of self-realization with successful social relations,clarifies the successful living structure of the human subject and promotes man’s self-realization. Honneth’s normative social theory focuses on man’s individuality and re-alization of man’s self-worth,which gives a special perspective for the present social construction and there-fore has some enlightenment.

  18. First record of eocene bony fishes and crocodyliforms from Canada's Western Arctic.

    Jaelyn J Eberle

    Full Text Available BACKGROUND: Discovery of Eocene non-marine vertebrates, including crocodylians, turtles, bony fishes, and mammals in Canada's High Arctic was a critical paleontological contribution of the last century because it indicated that this region of the Arctic had been mild, temperate, and ice-free during the early - middle Eocene (∼53-50 Ma, despite being well above the Arctic Circle. To date, these discoveries have been restricted to Canada's easternmost Arctic - Ellesmere and Axel Heiberg Islands (Nunavut. Although temporally correlative strata crop out over 1,000 km west, on Canada's westernmost Arctic Island - Banks Island, Northwest Territories - they have been interpreted as predominantly marine. We document the first Eocene bony fish and crocodyliform fossils from Banks Island. PRINCIPAL FINDINGS: We describe fossils of bony fishes, including lepisosteid (Atractosteus, esocid (pike, and amiid, and a crocodyliform, from lower - middle Eocene strata of the Cyclic Member, Eureka Sound Formation within Aulavik National Park (∼76°N. paleolat.. Palynology suggests the sediments are late early to middle Eocene in age, and likely spanned the Early Eocene Climatic Optimum (EECO. CONCLUSIONS/SIGNIFICANCE: These fossils extend the geographic range of Eocene Arctic lepisosteids, esocids, amiids, and crocodyliforms west by approximately 40° of longitude or ∼1100 km. The low diversity bony fish fauna, at least at the family level, is essentially identical on Ellesmere and Banks Islands, suggesting a pan-High Arctic bony fish fauna of relatively basal groups around the margin of the Eocene Arctic Ocean. From a paleoclimatic perspective, presence of a crocodyliform, gar and amiid fishes on northern Banks provides further evidence that mild, year-round temperatures extended across the Canadian Arctic during early - middle Eocene time. Additionally, the Banks Island crocodyliform is consistent with the phylogenetic hypothesis of a Paleogene divergence

We reexamined the 1961 raw data by grouping the QEI into five island-complexes ('eco-units' and calculating, for each unit, the estimated number of caribou and the standard error, and the 95% confidence interval of the estimate, using a 'bootstrap' technique with 100 000 replications. Our goal was to provide an ecological basis for evaluating subsequent changes in numbers rather than relying on single-island evaluations. Our bootstrap reanalysis produced an estimate of 28 288 ± 2205 SE with a 95% CI of 20 436—37 031 Peary caribou on the QEI in summer 1961. Substantial differences in density were apparent among the five eco-units, with about a 50-fold difference from 0.01 caribou • km-2 in the Eastern eco-unit to 0.5 caribou • km-2 in the Northwestern eco-unit. The 1961 findings, with our subsequent reexamination, are crucial to any evaluation of trends for the number of Peary caribou on the QEI and the relative importance of individual eco-units for these animals. These findings also allow a more accurate evaluation of the magnitude of the subsequent decline of Peary caribou on the QEI during the last four decades and may help predict future potential levels for caribou in each of the five eco-units.

    Full Text Available O artigo decorre de uma pesquisa empírica na área do direito sobre a relação entre Direito de Patente, Biodiversidade e Conhecimento Tradicional associado. O objeto da pesquisa é a Psychotria ipecacuanha, nome científico da planta Poaia, dotada de excepcionais qualidades medicinais e de extrema importância na exploração econômica do Brasil Colonial. Levando em conta os marcos normativos internacionais TRIPS e CDB, verifica-se a hipótese de estes não alterarem o processo de expropriação colonial e biopirataria praticados contra os grupos detentores de conhecimento tradicional. Para tanto, a partir de uma metodologia de pesquisa empírica, recolhem-se patentes relacionadas a essa planta depositadas na OMPI e, em 23/02/2016, selecionam-se cinco patentes referentes à espécie. Embasado nos marcos normativos de Bankowski, que trata da relação entre Direito e Amor e da ontologia moral da Luta pelo Reconhecimento de Axel Honneth, conclui-se o trabalho com a realização de inferências que revelam as dificuldades inerentes ao sistema de patentes derivadas de uma concepção legalista do direito e, principalmente, dos marcos normativos do TRIPS e da CDB em estabelecer uma relação harmônica entre o saber tradicional e a cultura ocidental.

    The 24 h dietary recall is a widely used method to estimate nutritional intakes in epidemiological studies. The objective of the present study was to estimate the number of recalls necessary for an accurate estimation of nutrient intake in French adults followed for 4 y. Participants of the SU.VI.MAX study (intervention study on the effects of antioxidant supplementation on chronic diseases) who completed a 24 h dietary recall every 2 months for at least 1 y. Inter- and intra-individual variance ratios (S(w)/S(b)) were calculated by analysis of variance for two time periods: year 1 and 2 (n=4955) and year 3 and 4 (n=1458). The number of recalls necessary was calculated using an accuracy of 0.9. The highest intra-individual/inter-individual variance ratio in the first period was seen for beta-carotene and the lowest for carbohydrate. The number of recalls necessary was five for carbohydrate and calcium intake and 16 for beta-carotene. For proteins, total and saturated fat, fibre, vitamin C and iron eight recalls were required, while nine, 11 and 10 recalls were necessary for mono- and polyunsaturated fat and vitamin E, respectively. The variance ratios in the second period were all lower and fewer recalls were therefore required. The same difference in number of recalls required between the two time periods was observed when only those subjects were included who completed at least 18 recalls (n=727). These results indicate that for an accurate estimation of carbohydrate intake only, already five recalls are necessary. Fewer recalls may be needed during long-time follow-up.

    The aim of this study was to compare the biological synthesis of gold nanoparticles (AuNPs) generated using the aqueous extracts of outer oriental melon peel (OMP) and peach. The synthesized OMP-AuNPs and peach extract (PE)-AuNPs were characterized by ultraviolet–visible spectroscopy, field emission scanning electron microscopy, energy dispersive X-ray analysis, X-ray powder diffraction, Fourier transform infrared spectroscopy, and thermogravimetric analysis. The surface plasmon resonance spectra were obtained at 545 nm and 540 nm for OMP-AuNPs and PE-AuNPs, respectively. The estimated absolute crystallite size of the synthesized AuNPs was calculated to be 78.11 nm for OMP-AuNPs and 39.90 nm for PE-AuNPs based on the Scherer equation of the X-ray powder diffraction peaks. Fourier transform infrared spectroscopy results revealed the involvement of bioactive compounds present in OMP and peach extracts in the synthesis and stabilization of synthesized AuNPs. Both the OMP-AuNPs and PE-AuNPs showed a strong antibacterial synergistic activity when combined with kanamycin (9.38–20.45 mm inhibition zones) and rifampicin (9.52–25.23 mm inhibition zones), and they also exerted a strong synergistic anticandidal activity (10.09–15.47 mm inhibition zones) when combined with amphotericin B against five pathogenic Candida species. Both the OMP-AuNPs and PE-AuNPs exhibited a strong antioxidant potential in terms of 1,1-diphenyl-2-picrylhydraxyl radical scavenging, nitric oxide scavenging, 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) radical scavenging, and a reducing power, along with a strong proteasome inhibitory potential that could be useful in cancer drug delivery and cancer treatments. The PE-AuNPs showed comparatively higher activity than OMP-AuNPs, which could be attributed to the presence of rich bioactive compounds in the PE that acted as reducing and capping agents in the synthesis of PE-AuNPs. Overall, the results of the current investigation

    Full Text Available The present paper reports the synthesis and characterization, photoluminescence thermoluminescence and mechanoluminescence studies of Ce3+ doped SrZrO3 phosphors. The effects of variable concentration of Cerium on meachanoluminescence (ML and photoluminescence behavior were studied. The samples were prepared by combustion a synthesis technique which is suitable for less time taking techniques also for large scale production for phosphors. The starting material used for sample preparation are Sr(NO33, Zr(NO33 XH2O and Ce(NO33 6H2O and urea used as a fuel. The prepared sample was characterized by X-ray diffraction technique (XRD with variable concentration of Ce (0.05–0.5 mol%. There is no any phase change found with increase the concentration of Ce. Sample shows orthorhombic structure and the particle size calculated by Scherer's formula. The surface morphology of prepared phosphor was determined by field emission gun scanning electron microscopy (FEGSEM technique. Mechanoluminescence studies on SrZrO3phosphors doped with Ce and underwent an impulsive deformation with an impact of a piston for Mechanoluminescence (ML investigations. Temporal characteristics in order to investigate about the luminescence centre responsible for ML peak, increasing impact velocity causes more number of electrons will be ionized to reach to the conduction band so there will be more number of electrons available to be recombined at recombination or luminescence centre. In photoluminescence study PL emission spectra show the isolated peak position observed at 388 nm near UV region of spectrum due to 5d–4f transition of Ce3+ion.Thermoluminescence study shows doping of Ce3+ ions reduced the TL intensity TL glow curve shows the high fading and less stability when it doped with cerium. The activation energy high for the doped SrZrO3 phosphor means that the trapped electron is highly trapped in trap level. The present study gives the advance application for fracture

    Rotational analyses have been carried out for the overtones of the nu(4) (torsion) and nu(6) (in-plane cis-bend) vibrations of the A (1)A(u) state of C(2)H(2). The v(4)+v(6)=2 vibrational polyad was observed in high-sensitivity one-photon laser-induced fluorescence spectra and the v(4)+v(6)=3 polyad was observed in IR-UV double resonance spectra via the ground state nu(3) (Sigma(+) (u)) and nu(3)+nu(4) (Pi(u)) vibrational levels. The structures of these polyads are dominated by the effects of vibrational angular momentum: Vibrational levels of different symmetry interact via strong a-and b-axis Coriolis coupling, while levels of the same symmetry interact via Darling-Dennison resonance, where the interaction parameter has the exceptionally large value K(4466)=-51.68 cm(-1). The K-structures of the polyads bear almost no resemblance to the normal asymmetric top patterns, and many local avoided crossings occur between close-lying levels with nominal K-values differing by one or more units. Least squares analysis shows that the coupling parameters change only slightly with vibrational excitation, which has allowed successful predictions of the structures of the higher polyads: A number of weak bands from the v(4)+v(6)=4 and 5 polyads have been identified unambiguously. The state discovered by Scherer et al. [J. Chem. Phys. 85, 6315 (1986)], which appears to interact with the K=1 levels of the 3(3) vibrational state at low J, is identified as the second highest of the five K=1 members of the v(4)+v(6)=4 polyad. After allowing for the Darling-Dennison resonance, the zero-order bending structure can be represented by omega(4)=764.71, omega(6)=772.50, x(44)=0.19, x(66)=-4.23, and x(46)=11.39 cm(-1). The parameters x(46) and K(4466) are both sums of contributions from the vibrational angular momentum and from the anharmonic force field. For x(46) these contributions are 14.12 and -2.73 cm(-1), respectively, while the corresponding values for K(4466) are -28.24 and -23

Chalcones are compounds of low water solubility that have been described as promising molecules for the treatment of cutaneous leishmaniasis (CL. In this context, the aim of this work was to optimize the development of a nanoemulsion containing a synthetic chalcone for CL treatment using a 22 full factorial design. The formulations were prepared by spontaneous emulsification and the experimental design studied the influence of two independent variables (type of surfactant – soybean lecithin or sorbitan monooleate and type of co-surfactants – polysorbate 20 or polysorbate 80 on the physicochemical characteristics of the nanoemulsions, as well as on the skin permeation/retention of the synthetic chalcone in porcine skin. In order to evaluate the stability of the systems, the antileishmanial assay was performed against Leishmania amazonensis 24 hours and 60 days after the preparation of the nanoemulsions. The formulation composed of soybean lecithin and polysorbate 20 presented suitable physicochemical characteristics (droplet size

    An intense field campaign from the Ice Nuclei Research Unit (INUIT) was performed in January and February of 2013 at the High-Alpine Research Station Jungfraujoch (3580 m a.s.l., Switzerland). Main goal was the assessment of microphysical and chemical properties of free-tropospheric ice-nucelating particles. The ice-nucleating particles were discriminated from the total aerosol with the 'Fast Ice Nucleation CHamber' (FINCH; University Frankfurt) and the 'Ice-Selective Inlet' (ISI, Paul Scherer Institute) followed by a pumped counter-stream virtual impactor. The separated ice-nucleating particles were then collected with a nozzle-type impactor. With the 'FRankfurt Ice nuclei Deposition freezinG Experiment' (FRIDGE), aerosol particles are sampled on a silicon wafer, which is than exposed to ice-activating conditions in a static diffusion chamber. The locations of the growing ice crystals are recorded for later analysis. Finally, with the ICE Counter-stream Virtual Impactor (ICE-CVI) atmospheric ice crystals are separated from the total aerosol and their water content is evaporated to retain the ice residual particles, which are then collected also by impactor sampling. All samples were analyzed in a high-resolution scanning electron microscope. By this method, for each particle its size, morphology, mixing-state and chemical composition is obtained. In total approximately 1700 ice nucleating particles were analyzed. Based on their chemical composition, the particles were classified into seven groups: silicates, metal oxides, Ca-rich particles, (aged) sea-salt, soot, sulphates and carbonaceous matter. Sea-salt is considered as artifact and is not regarded as ice nuclei here. The most frequent ice nucleating particles/ice residuals at the Jungfraujoch station are silicates > carbonaceous particles > metal oxides. Calcium-rich particles and soot play a minor role. Similar results are obtained by quasi-parallel measurements with an online single particle laser ablation

Midazolam has been shown to inhibit ion channels, including calcium and potassium channels. So far, the effects of midazolam on cardiac human ether-à-go-go-related gene (hERG channels have not been analyzed. The inhibitory effects of midazolam on heterologously expressed hERG channels were analyzed in Xenopus oocytes using the double-electrode voltage clamp technique. We found that midazolam inhibits hERG channels in a concentration-dependent manner, yielding an IC50 of 170 µM in Xenopus oocytes. When analyzed in a HEK 293 cell line using the patch-clamp technique, the IC50 was 13.6 µM. Midazolam resulted in a small negative shift of the activation curve of hERG channels. However, steady-state inactivation was not significantly affected. We further show that inhibition is state-dependent, occurring within the open and inactivated but not in the closed state. There was no frequency dependence of block. Using the hERG pore mutants F656A and Y652A we provide evidence that midazolam uses a classical binding site within the channel pore. Analyzing the subacute effects of midazolam on hERG channel trafficking, we further found that midazolam does not affect channel surface expression. Taken together, we show that the anesthetic midazolam is a low-affinity inhibitor of cardiac hERG channels without additional effects on channel surface expression. These data add to the current understanding of the pharmacological profile of the anesthetic midazolam. Keywords: midazolam, anesthetics, human ether

    The effects of heat treatment on a nano-crystalline spinel ferrite with chemical formula CoCr{sub 0.04}Ce{sub x}F{sub e1.96−x}O{sub 4} (x=0.06) were investigated in the present work. The sample was prepared by the auto-combustion method and then heat treated at 700–1200 °C for 8 h. The sample heat treated at these temperatures was investigated using thermo-gravimetric analyses and differential scanning calorimetry, X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy and vibrating sample magnetometery. The XRD patterns and IR spectra confirmed that the synthesized materials were of single phase at and above 900 °C. The average particle size was found to be in the range of 30.8–63.8 nm estimated by the Scherer formula. IR studies confirm two main absorption bands in the frequency range of 400–800 cm{sup −1} arising due to the tetrahedral (A-site) and octahedral (B-site) stretching vibrations. The average grain size increased with the increase of temperature while distribution of particles became homogeneous as observed by scanning electron microscope. The saturation magnetization was increased gradually from 7.4 to 59.6 emu/g with the increase of temperature. The coercivity lies in the range of 248–811 Oe as a function of temperature. The obtained results suggest that the investigated materials may be potential candidates for high density recording media applications. - Highlights: • Effects of temperature on structural and magnetic parameters of spinel ferrite are studied. • The XRD patterns confirms that the materials are of single phase at and above 900 °C. • The M{sub s} was increased gradually from 7.4–59.6 emu/g with the increase of temperature. • The values of coercivity lie in the range of 248–811 Oe as a function of temperature. • The results show that materials may have a potential for high density recording media.

    A portable microfabricated capillary electrophoresis (CE) system named the Mars Organic Analyzer (MOA) has been developed to analyze fluorescently-labeled biomarkers including amino acids, amines, nucleobases, and amino sugars with the goal of life detection on Mars (1,2). This technology has also been shown to be effective in screening the formation of biogenic amines during fermentation (3). The MOA is a part of the Urey instrument package that has been selected for the 2016 European ExoMars mission by ESA. The identification of recent gully erosion sites, observations of ice on and beneath the surface of Mars, and the discovery of large reservoirs of sub-surface ice on Mars point to water-ice as an important target for astrobiological analyses. In addition, the ice samples on the Moon, Mercury, Europa and Enceladus are of interest due to the possibility that they may contain information on biogenic material relevant to the evolution of life. We explore here the use of the MOA instrument for the analysis of amino acids in polar ice samples. The amino acids valine, alanine/serine, glycine, glutamic acid, and aspartic acid were found in the parts-per-billion range from Greenland ice-core samples. Chiral analysis of these samples yielded D/L ratios of 0.51/0.09 for alanine/serine and 0.14/0.06 for aspartic acid. Individual amino acids in the parts-per-trillion range were found in Antarctic ice samples collected from the surface of a meteorite collection area. The distinct amino acid and amine content of these samples indicates that further biomarker characterization of ice samples as a function of sampling location, depth, and structural features will be highly informative. The rapid sensitive analysis capabilities demonstrated here establish the feasibility of using the MOA to analyze the biomarker content of ice samples in planetary exploration. 1. Skelley, A.

    See Scherer (doi:10.1093/awv279) for a scientific commentary on this article.Charcot-Marie-Tooth type 1 neuropathies are inherited disorders of the peripheral nervous system caused by mutations in Schwann cell-related genes. Typically, no causative cure is presently available. Previous preclinical data of our group highlight the low grade, secondary inflammation common to distinct Charcot-Marie-Tooth type 1 neuropathies as a disease amplifier. In the current study, we have tested one of several available clinical agents targeting macrophages through its inhibition of the colony stimulating factor 1 receptor (CSF1R). We here show that in two distinct mouse models of Charcot-Marie-Tooth type 1 neuropathies, the systemic short- and long-term inhibition of CSF1R by oral administration leads to a robust decline in nerve macrophage numbers by ∼70% and substantial reduction of the typical histopathological and functional alterations. Interestingly, in a model for the dominant X-linked form of Charcot-Marie-Tooth type 1 neuropathy, the second most common form of the inherited neuropathies, macrophage ablation favours maintenance of axonal integrity and axonal resprouting, leading to preserved muscle innervation, increased muscle action potential amplitudes and muscle strengths in the range of wild-type mice. In another model mimicking a mild, demyelination-related Charcot-Marie-Tooth type 1 neuropathy caused by reduced P0 (MPZ) gene dosage, macrophage blockade causes an improved preservation of myelin, increased muscle action potential amplitudes, improved nerve conduction velocities and ameliorated muscle strength. These observations suggest that disease-amplifying macrophages can produce multiple adverse effects in the affected nerves which likely funnel down to common clinical features. Surprisingly, treatment of mouse models mimicking Charcot-Marie-Tooth type 1A neuropathy also caused macrophage blockade, but did not result in neuropathic or clinical improvements

Therefore, patient involvement in the development process is essential. However, there is no methodological gold standard for involving patients in QI development. The aim of this study is to explore experts’ views on the representation of patient-relevant aspects in the QI development process using the QIs developed in the context of the German National Disease Management Guideline for Heart Failure as an example. Methods: Semi-structured, open telephone interviews were conducted with 15 German experts (patient representatives, physicians, researchers, and methodologists involved in guideline development or quality assessment. Interview themes were the relevance of the exemplary set of QIs for patients, as well as the legitimacy of, competence of, and collaboration with the patient representative who participated in the development process. Interviews were fully transcribed and content analyzed. Deductive categories derived from the research questions were supplemented by inductively formed categories during the review of the interview material.Results: The qualitative analysis suggests a discrepancy between the guidelines’ QIs and those relevant to patients from an expert’s point of view, such as physician-patient communication and quality of counseling. Experts reported only minor communication and cooperation

    Structural, magnetic and magnetocaloric properties of the nanocrystalline La0.7Te0.3Mn1-xFexO3 (x=0.1 and 0.3) perovskite manganites were investigated prepared by the sol-gel method. X-ray diffraction indicates that the samples crystallize in rhombohedral crystal structure with R 3 ̅c space group for x=0.1 and orthorhombic structure with Pbnm space group for x=0.3. The average crystallite sizes were calculated using Debye Scherer's formula and were found to be 31 nm and 26 nm for La0.7Te0.3Mn0.90Fe0.1O3 and La0.7Te0.3Mn0.7Fe0.3O3 samples, respectively. The scanning electron microscopy images confirm the homogeneity of the nanocrystalline samples. Temperature dependence magnetization measurements revealed a decrease of ferromagnetic-paramagnetic phase transition with increasing Fe-content. The Curie temperature (TC) determined for x=0.1 and 0.3 are 171 K and 78 K, respectively. Based on the magnetic field dependence of magnetization, M(H), the magnetic entropy change |ΔSM| of the samples were calculated. The maximum entropy change |ΔSmax| values are 1.17 Jkg-1 K-1 for x=0.1 and 0.44 Jkg-1 K-1 for x=0.3 for a field change of 2 T. The relative cooling power was found to be 80 JK-1 and 49 JK-1 for the La0.7Te0.3Mn0.90Fe0.1O3 and La0.7Te0.3Mn0.7Fe0.3O3 samples, which are comparable to other manganites. Tuning of TC with Fe substitution on Mn-site and moderate magnetic entropy change and RCP values, as well as high stability, enable La0.7Te0.3Mn1-xFexO3 (x=0.1 and 0.3) nanocrystalline manganites to be a competitive candidate among the magnetic refrigeration materials for wide temperature ranges from room temperature down to 50 K.

    Full Text Available This paper reports the thermoluminescence properties of Er3+ doped gadolinium oxide nanophosphor. The phosphor is prepared by high temperature solid state reaction method. The method is suitable for large scale production. Starting materials used for sample preparation were Gd2O3, Er2O3 (0.5–2.5 mol% and fixed concentration of boric acid using as a flux. The prepared samples were characterized by X-ray diffraction technique and the particle size calculated by Scherer's formula. The surface morphology of prepared phosphor is determined by scanning electron microscopic (SEM technique. Functional group analysis was done by Fourier transform infra-red spectroscopy (FTIR analysis. The elemental analysis of prepared sample was determined by energy dispersive X-ray analysis (EDX and the exact particle size of prepared phosphor for the different concentration of dopant (Er3+ was evaluated by transmission electron microscopy (TEM technique. The prepared phosphors for different concentration of Er3+ were examined by thermoluminescence (TL glow curve for UV and gamma irradiation. The UV 254 nm source was used for UV irradiation and Co60 source was used for gamma irradiation. The samples show well resolved broad peak covered the temperature range 50–250 °C and the peak temperature found at 126 °C for UV irradiation and higher temperature peak at 214 °C for gamma irradiation. The effect of heating rate on TL studies was presented for optimized sample. Here UV irradiated sample shows the formation of shallow trap (surface trapping and the gamma irradiated sample shows the formation of deep trapping. The estimation of trap formation was evaluated by knowledge of trapping parameters. The trapping parameters such as activation energy, order of kinetics and frequency factor were calculated by peak shape method. Here most of the peak shows second order of kinetics. The effect of gamma and UV exposure on TL studies was also examined and it shows linear

    The aim of this study was to compare the biological synthesis of gold nanoparticles (AuNPs) generated using the aqueous extracts of outer oriental melon peel (OMP) and peach. The synthesized OMP-AuNPs and peach extract (PE)-AuNPs were characterized by ultraviolet-visible spectroscopy, field emission scanning electron microscopy, energy dispersive X-ray analysis, X-ray powder diffraction, Fourier transform infrared spectroscopy, and thermogravimetric analysis. The surface plasmon resonance spectra were obtained at 545 nm and 540 nm for OMP-AuNPs and PE-AuNPs, respectively. The estimated absolute crystallite size of the synthesized AuNPs was calculated to be 78.11 nm for OMP-AuNPs and 39.90 nm for PE-AuNPs based on the Scherer equation of the X-ray powder diffraction peaks. Fourier transform infrared spectroscopy results revealed the involvement of bioactive compounds present in OMP and peach extracts in the synthesis and stabilization of synthesized AuNPs. Both the OMP-AuNPs and PE-AuNPs showed a strong antibacterial synergistic activity when combined with kanamycin (9.38-20.45 mm inhibition zones) and rifampicin (9.52-25.23 mm inhibition zones), and they also exerted a strong synergistic anticandidal activity (10.09-15.47 mm inhibition zones) when combined with amphotericin B against five pathogenic Candida species. Both the OMP-AuNPs and PE-AuNPs exhibited a strong antioxidant potential in terms of 1,1-diphenyl-2-picrylhydraxyl radical scavenging, nitric oxide scavenging, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) radical scavenging, and a reducing power, along with a strong proteasome inhibitory potential that could be useful in cancer drug delivery and cancer treatments. The PE-AuNPs showed comparatively higher activity than OMP-AuNPs, which could be attributed to the presence of rich bioactive compounds in the PE that acted as reducing and capping agents in the synthesis of PE-AuNPs. Overall, the results of the current investigation highlighted a

    A series of the divalent and trivalent co-substituted Mg{sub 0.5−x}Cd{sub x}Co{sub 0.5}Cr{sub 0.04}Tb{sub y}Fe{sub 1.96−y}O{sub 4} spinel ferrite systems (where x=0–0.5 in steps of 0.1 and y=0.00–0.10 in steps 0.02) are synthesized by sol–gel auto combustion method. The product materials were characterized by the thermo gravimetric analysis and differential scanning calorimetry (TGA/DSC), Fourier transform infrared spectra (FTIR), nitrogen adsorption (BET), X-ray diffraction (XRD), scanning electron microscope (SEM), atomic force microscopy (AFM) and vibrating sample magnetometer (VSM). The X-ray diffraction patterns and Fourier transform infrared spectroscopy confirm spinel nanocrystalline phase. The crystallite size is determined by Scherer's formula from 36.6 to 69.4 nm. The X-ray density is found in the range of 5.09–6.43 (g/cm{sup 3}). The morphological features are studied using scanning electron microscope and AFM. Saturation magnetization (M{sub s}) and remanence (M{sub r}) magnetization extracted from M–H loops exhibit the decreasing trends 21.4–16 emu/g and 9.1–6.3 emu/g, respectively. A significant decrease in the intrinsic parameters is observed in the prepared samples due to the weakening of the A–B interaction as iron enters into the tetrahedral A-site. The coercivity lies in the range of 300–869 Oe as a function of co-substitution contents. The coercivity of the sample with x=0.1, y=0.02 was found maximum i.e. 869 Oe. The obtained results suggest that the investigated materials may be potential candidates for high density recording media applications. - Highlights: • Effects of co-substitution (Cd{sup 2+}, Tb{sup 3+}) on structural and magnetic parameters are studied. • XRD patterns revealed that first three samples are single phase while others are biphasic. • The M{sub s} was decreased from 21.4 to 16 emu/g with increasing co-substituted contents. • The values of coercivity lie in range of 300–869 Oe for all

    Natural emissions of ozone and aerosol precursor gases such as isoprene and monoterpenes are the highest in the southeast of the U.S. and rival those found in tropical forests. In addition, anthropogenic emissions are significant in the Southeast and photochemistry is rapid. The southeast U.S. has not warmed like other parts of the U.S. in response to global climate change, and the temperature anomaly has been suggested to be related to aerosols derived from a combination of anthropogenic and biogenic precursors. The NOAA SENEX aircraft campaign took place in June-July 2013 in the southeast U.S. as part of the Southeast Atmosphere Study (SAS). The NOAA WP-3 aircraft conducted 20 research flights between May 27 and July 10, 2013 based out of Smyrna, TN. To investigate the combination of anthropogenic and biogenic emissions several flights were designed to follow the emissions of cities and power plants as they are transported over forested regions in the Southeast. For example, over-flights of Atlanta, Birmingham and Nashville were performed and the plumes were followed to the forested areas with high isoprene and monoterpene emissions. The same was done for several power plants such as EC Gaston, Scherer and Johnsonville. In the anthropogenic plumes, effects such as the modulation of the isoprene chemistry by high NOx and particle formation and growth were investigated. The same strategy was used for three nighttime flights over Atlanta, Birmingham and the New Madrid and White Bluff power plants. Flights over and downwind of St Lois and Indianapolis were used as a contrast in areas with smaller biogenic emissions. Other anthropogenic emissions sources that were investigated during SENEX included bio refineries, paper mills, coalmines, poultry and pork farming. Also biomass burning emissions were observed during one daytime and one nighttime flight. Another focus of the SENEX campaign was to determine the emissions of natural gas and oil production from the

    Urban populations are highly vulnerable to the adverse effects of heat, with heat-related mortality showing intra-urban variations that are likely due to differences in urban characteristics and socioeconomic status. We investigated the influence of urban green and urban blue, that is, urban vegetation and water bodies, on heat-related excess mortality in the elderly > 65 years old in Lisbon, Portugal, between 1998 and 2008. We used remotely sensed data and geographic information to determine the amount of urban vegetation and the distance to bodies of water (the Atlantic Ocean and the Tagus Estuary). Poisson generalized additive models were fitted, allowing for the interaction between equivalent temperature [universal thermal climate index (UTCI)] and quartiles of urban greenness [classified using the Normalized Difference Vegetation Index (NDVI)] and proximity to water (≤ 4 km vs. > 4 km), while adjusting for potential confounders. The association between mortality and a 1°C increase in UTCI above the 99th percentile (24.8°C) was stronger for areas in the lowest NDVI quartile (14.7% higher; 95% CI: 1.9, 17.5%) than for areas in the highest quartile (3.0%; 95% CI: 2.0, 4.0%). In areas > 4 km from water, a 1°C increase in UTCI above the 99th percentile was associated with a 7.1% increase in mortality (95% CI: 6.2, 8.1%), whereas in areas ≤ 4 km from water, the estimated increase in mortality was only 2.1% (95% CI: 1.2, 3.0%). Urban green and blue appeared to have a mitigating effect on heat-related mortality in the elderly population in Lisbon. Increasing the amount of vegetation may be a good strategy to counteract the adverse effects of heat in urban areas. Our findings also suggest potential benefits of urban blue that may be present several kilometers from a body of water.

The XRD and FTIR analysis show the single phase of the prepared material. The lattice constants a (Å) and c (Å) varies with the additives. The particle size measured by Scherer formula for all the samples varies in the range of 54–100 nm and confirmed by the TEM analysis. The average grain size measured by SEM analysis lies in the range of 0.672–1.01 µm for all the samples. The Gd-substituted ferrite has higher value of coercivity (526.06 G) among all the samples which could be a good material for longitudinal recording media. The results also indicate that the Gd-substituted sample has maximum reflection loss of −25.2 dB at 11.878 GHz, can exhibit the best microwave absorption properties among all the substituted samples. Furthermore, the minimum value of reflection loss shifts towards the lower and higher frequencies with the substitution of rare earth elements which confirms that the microwave absorption properties can be tuned with the substitution of rare earth elements in pure ferrites. The peak value of attenuation constant at higher frequency agrees well the reflection loss data. - Highlights: • A series of X-type hexagonal ferrites were prepared by sol–gel method. • The XRD analysis showed that the X-type hexagonal structure. • The c/a ratio of these samples falls in the range of X-type hexagonal ferrites. • FTIR spectra confirms single hexagonal phase. • The magnetic properties vary with the substitution of rare earth elements. • The Gd-doped sample exhibits maximum absorption properties and coercivity.

    We describe the characteristics and the capabilities of the laboratory facility, COSmIC, that was developed at NASA Ames to generate, process and analyze interstellar, circumstellar and planetary analogs in the laboratory [1]. COSmIC stands for "Cosmic Simulation Chamber" and is dedicated to the study of neutral and ionized molecules and nanoparticles under the low temperature and high vacuum conditions that are required to simulate various space environments such as planetary atmospheres. COSmIC integrates a variety of state-of-the-art instruments that allow forming, processing and monitoring simulated space conditions for planetary, circumstellar and interstellar materials in the laboratory. The COSmIC experimental setup is composed of a Pulsed Discharge Nozzle (PDN) expansion, that generates a plasma in the stream of a free supersonic jet expansion, coupled to two high-sensitivity, complementary in situ diagnostics: a Cavity Ring Down Spectroscopy (CRDS) and laser induced fluorescence (LIF) systems for photonic detection [2, 3], and a Reflectron Time-Of-Flight Mass Spectrometer (ReTOF-MS) for mass detection [4].Recent results obtained using COSmIC will be highlighted. In particular, the progress that has been achieved in an on-going study investigating the formation and the characterization of laboratory analogs of Titan's aerosols generated from gas-phase molecular precursors [5] will be presented. Plans for future laboratory experiments on planetary molecules and aerosols in the growing field of planetary laboratory astrophysics will also be addressed, as well as the implications of studies underway for astronomical observations.References: [1] Salama F., in Organic Matter in Space, IAU S251, Kwok & Sandford eds, CUP, S251, 4, 357 (2008).[2] Biennier L., Salama, F., Allamandola L., & Scherer J., J.

    The nanocrystalline Mg{sub 0.5}Zn{sub 0.5−x}Co{sub x}Fe{sub 2}O{sub 4} (x=0, 0.1, 0.2, 0.3, 0.4 and 0.5) ferrites have been synthesized by sol–gel auto ignition method. Rietveld refinement of X-ray diffraction (XRD) patterns of all concentrations show mixed cubic spinel structure. The lattice constant values infer decreasing trend from 8.420 to 8.392 Å with the substitution of Co{sup 2+}. The crystallite size calculated from Scherer formula lies in the range between 28 and 37 nm which confirms the nanocrystalline nature of synthesized samples. In order to study the morphology and phase structure of the synthesized samples, samples were examined by transmission electron microscopy (TEM). Scanning electron microscopy (SEM) confirmed the homogeneous and well defined surface morphology of the synthesized samples. The elemental analysis as obtained from energy dispersive X-ray (EDAX) is in close agreement with the expected composition from the stoichiometry of reactant solutions used. The valence states of the Co{sup 2+} ions have been confirmed with the help of X-ray photoelectron spectroscopy. Magnetization results obtained from the vibrating sample magnetometer (VSM) confirm that the substitution of Co{sup 2+} for Zn{sup 2+} caused an increase in the saturation magnetization and coercivity. The dependence of Mössbauer parameters, viz., line width, isomer shift, quadrupole splitting and hyperfine magnetic field on Co{sup 2+} substitution have been analyzed. Cation distribution estimated from XRD and Mössbauer spectroscopy are in good agreement with each other. The frequency dependent dielectric properties were studied by measuring dielectric constant (ε') and ac conductivity (σ{sub ac}) at 300 K in the frequency range of 50 Hz–5 MHz. The highest value for ε' and σ{sub ac} is observed for x=0.5. - Highlights: • Co{sup 2+} incorporated Mg–Zn ferrite synthesized by novel auto combustion. • Structural analysis with Retvield confirms the

A subsequent placebo-controlled, single-blind, crossover study involved consumption of 500 mg ACE, 250 mg ACE, or 0 mg ACE (placebo per day for 1-week duration, separated by 1-week washout period. Subjects: Adult subjects of both sexes, with chronic joint-related pain for at least 6 months prior to enrollment, were recruited after obtaining written informed consent. Outcome measures: Visual analog scales were used to score pain at rest and during physical activity for each person's primary and secondary areas of chronic pain. An activities of daily living questionnaire was used to collect data on physical functioning. Results: The data showed rapid reduction of chronic pain in people consuming ACE, where the reduction in pain scores for each person's primary pain area reached a high level of statistical significance after 2 weeks of consumption (P<0.01, both when at rest and when being physically active. Secondary pain areas when physically active showed highly significant improvements within 1 week of consumption of 1 g/d (P<0.001 and borderline significant improvements within 1 week of consuming 500 mg/d (P<0.065 and 250 mg/d (P<0.05. This was accompanied by an increased ability to perform daily activities (P<0.05. A small but significant weight loss was observed during the 4-week study, as the average body mass index dropped from 31.4 to 29.4 (P<0.01. Conclusion: Consumption of ACE was associated

  11. EPONYMY BASED ON NAMES OF COMPANIES

    Full Text Available As is generally defined, eponymy, one of the word-formation processes refers to the derivation of a name of a city, country, era, institution, or other place or thing from that of a person such as sandwich, wellington, mackintosh or cardigan. Eponymy can be classified in several ways, some refer to foods (Pizza Margaritha, diseases (Alzheimer disease, places (Washington, scientific laws (Archimedes’s principle and sport terms (Axel jump, whereas others indicate trademarks, brand names (aspirin, prizes, awards (Nobel Prize, inventions (Rubic’s Cube, ideologies (Darwinism, colleges, universities (Stanford University and companies (Ford. The present paper discusses eponyms which denote companies based on the name of their founder(s (e.g. Porsche, Siemens, Gucci, Campari, Cadbury, McDonald’s and Walt Disney, etc. by revealing what kind of a metonymic relationship is manifested in them. Cognitive linguists, such as Lakoff and Johnson (1980, Radden and Kövecses (1999 and Kövecses (2002 state that metonymy is essentially a conceptual phenomenon, in which one conceptual entity, the vehicle, provides mental access to another conceptual entity, the target, within the same idealized cognitive model. In fact, metonymy is part of our everyday way of thinking, and is grounded in experience. Common metonymies include PRODUCER FOR PRODUCT (Pass me the Shakespeare on the top shelf., PLACE FOR EVENT (Iraq nearly cost Tony Blair the premiership, PLACE FOR INSTITUTION (Downing Street refused comment., PART FOR THE WHOLE (She’s not just a pretty face., WHOLE FOR THE PART (England beat Australia in the 2003 Rugby World Cup final. and EFFECT FOR CAUSE (He has a long face.. Following the cognitive approach to metonyms, I tentatively suggest that the metonymy PRODUCER FOR THE PRODUCT can be observed in the case of car makes, products of famous fashion houses, cosmetics and drinks as is illustrated by examples like He’s bought a Ferrari.

    Background: γ strength functions (GSFs) and level densities (LDs) are essential ingredients of statistical nuclear reaction theory with many applications in astrophysics, reactor design, and waste transmutation. Purpose: The aim of the present work is a test of systematic parametrizations of the GSF recommended by the RIPL-3 database for the case of 208Pb. The upward GSF and LD in 208Pb are compared to γ decay data from an Oslo-type experiment to examine the validity of the Brink-Axel (BA) hypothesis. Methods: The E 1 and M1 parts of the total GSF are determined from high-resolution forward angle inelastic proton scattering data taken at 295 MeV at the Research Center for Nuclear Physics (RCNP), Osaka, Japan. The total LD in 208Pb is derived from the 1- LD extracted with a fluctuation analysis in the energy region of the isovector giant dipole resonance. Results: The E 1 GSF is compared to parametrizations recommended by the RIPL-3 database showing systematic deficiencies of all models in the energy region around neutron threshold. The new data for the poorly known spin-flip M 1 resonance call for a substantial revision of the model suggested in RIPL-3. The total GSF derived from the present data is larger in the PDR energy region than the Oslo data but the strong fluctuations due to the low LD resulting from the double shell closure of 208Pb prevent a conclusion on a possible violation of the BA hypothesis. Using the parameters suggested by RIPL-3 for a description of the LD in 208Pb with the back-shifted Fermi gas model, remarkable agreement between the two experiments spanning a wide excitation energy range is obtained. Conclusions: Systematic parametrizations of the E 1 and M 1 GSF parts need to be reconsidered at low excitation energies. The good agreement of the LD provides an independent confirmation of the approach underlying the decomposition of GSF and LD in Oslo-type experiments.

  13. The Cretaceous Polar and Western Interior seas: paleoenvironmental history and paleoceanographic linkages

    2014-03-01

    This study reviews the Cretaceous histories of the Polar and Western Interior seas as recorded in the Canadian High Arctic Sverdrup Basin, Beaufort-Mackenzie Basin of northwest Canada and Western Canadian Foreland Basin. Newly emerging stratigraphic, paleoclimatic and paleoenvironmental interpretations from the polar realm allow for a fresh look at the response of this oceanic system to global climatic trends and sea-level histories over 35 Ma. Sverdrup basin localities on Axel Heiberg and Ellef Ringnes islands represent shelf to slope environments that contrasted with the shallow water and low gradient settings of the Canadian Western Interior Sea. Both marine systems, connected throughout Aptian to Maastrichtian time, responded to global transgressive-regressive cycles resulting in dynamic paleogeographic changes. The upper Aptian to Campanian succession of the Polar Sea shows at least two unconformable boundaries; one at the Albian/Cenomanian transition and another within the upper Cenomanian. The shallow basin setting and in particular the forebulge and backbulge settings of the Western Canadian Foreland Basin are characterized by multiple erosional surfaces throughout the Cretaceous succession. The Upper Albian disconformity is widely discernible close to the entrance of the Western Interior Sea to the Polar Sea. This suggests a short-lived closure of the latest Albian Mowry Sea that might have been responsible for the large loss of benthic foraminiferal species at this time. Several oceanic anoxic events are documented in these basins representing their response to global climate dynamics. During the Late Cretaceous temperature maximum benthic foraminiferal communities were severely restricted by bottom water hypoxia in both basins. A stratified water column might have been the result of increased freshwater runoff under warm, humid conditions. These conditions supported vegetation up into the polar latitudes that added abundant organic matter to marine shelf

    The Argo programme is one of the most important elements of the ocean observing system. Currently almost 4000 Argo floats profile global oceans and deliver real time data. Originally Argo floats were developed for open ocean observations. Therefore a standard float can dive up to 2000 m and deep Argo floats are under development. However in the last years the shallow shelf seas become also interesting for Argo users. Institute of Oceanology Polish Academy of Sciences (IOPAN) participates in the Euro-Argo research infrastructure, the European contribution to Argo system. A legal and governance framework (Euro-Argo ERIC) was set up in May 2014. For a few years IOPAN has deployed floats mostly in the Nordic Seas and the European Arctic region. In the end of 2016 the first Polish Argo float was deployed in the Southern Baltic Sea. Building on the successful experience with Argo floats deployed by the Finnish oceanographers in the Bothnian Sea and Gotland Basin, the IOPAN float was launched in the Bornholm Deep during the fall cruise of IOPAN research vessel Oceania. The standard APEX float equipped with 2-way Iridium communication was used and different modes of operation, required for the specific conditions in the shallow and low saline Baltic Sea, were tested. Settings for the Baltic float are different than for the oceanic mode and were frequently changed during the mission to find the optimum solution. Changing the float parking depth during the mission allows for the limited control of the float drift direction. Results of a high resolution numerical forecast model for the Baltic Sea proved to be a valuable tool for determining the parking depth of the float in the different flow regimes. Trajectory and drift velocity of the Argo float deployed in the Southern Baltic depended strongly on the atmospheric forcing (in particular wind speed and direction), what was clearly manifested during the 'Axel' storm passing over the deployment area in January 2017.

Kaplan-Meier and multivariate Cox regression analyses concerning primary endpoint of cardiac mortality were performed.Results: A total of 609 patients received DES. Mean age was 66.2 ± 11.3 years, 69.4% were male, and 1517 (83.8% were treated for acute coronary syndrome (unstable angina 510 [28.2%], non-ST-elevation myocardial infarction [NSTEMI] 506 [28.0%], and ST-elevation myocardial infarction [STEMI] 501 [27.7%]. Mean follow-up was 34 ± 15 months. During follow-up, 268 patients died of cardiac causes (DES 42 [7.3%]; BMS 226 [19.6%]; P < 0.001. Univariate Kaplan-Meier analysis showed an advantage of DES over BMS concerning the primary endpoint (P < 0.001. When adjusting for classic risk factors and additional factors that affect the progression of coronary heart disease (CHD, DES was not found to be superior to BMS (hazard ratio 0.996, 95% confidence interval 0.455–2.182, P = 0.993. Severely impaired renal function was an independent predictor for cardiac mortality after stent implantation.Conclusion: Treatment with DES is safe in the long term, also in patients presenting with STEMI. However, in multivariate analyses it is not superior to BMS treatment.Keywords: coronary stent, outcome, renal insufficiency, myocardial infarction, STEMI

Creating clear data about complications that can affect the quality of life is an important tool for patients to decide whether and where to perform this extensive surgery. Hypothesis: A team of surgeons with a clear focus on pelvic surgery leads to lower complication rates in radical cystectomy. Materials and methods: Radical cystectomy was performed in two separate time periods under the patronage of two different chairmen in the same university hospital. The patient data were analyzed retrospectively and the complications 30 days after surgery were assessed using the Clavien–Dindo classification. Results: Statistical analysis showed a significant difference in the severity of complications between the two time periods, A and B, in total (P<0.001.

    The rate of CH4 release from thawing permafrost in the Arctic has been regarded as one of the determining factors on future global climate. It is uncertain how indigenous microorganisms would interact with such changing environmental conditions and hence their impact on the fate of carbon compounds that are sequestered in the cryosol. Multitudinous studies of pristine surface cryosol (top 5 cm) and microcosm experiments have provided growing evidence of effective methanotrophy. Cryosol samples corresponding to active layer were sampled from a sparsely vegetated, ice-wedge polygon at the McGill Arctic Research Station at Axel Heiberg Island, Nunavut, Canada (N79°24, W90°45) before the onset of annual thaw. Pyrosequencing of 16S rRNA gene indicated the occurrence of methanotroph-containing bacterial families as minor components (~5%) in pristine cryosol including Bradyrhizobiaceae, Methylobacteriaceae and Methylocystaceae within alpha-Proteobacteria, and Methylacidiphilaceae within Verrucomicrobia. The potential of methanotrophy is supported by preliminary analysis of metagenome data, which indicated putative methane monooxygenase gene sequences relating to Bradyrhizobium sp. and Pseudonocardia sp. are present. Proteome profiling in general yielded minute traces of proteins, which likely hints at dormant nature of the soil microbial consortia. The lack of specific protein database for permafrost posted additional challenge to protein identification. Only 35 proteins could be identified in the pristine cryosol and of which 60% belonged to Shewanella sp. Most of the identified proteins are known to be involved in energy metabolism or post-translational modification of proteins. Microcosms amended with sodium acetate exhibited a net methane consumption of ~65 ngC-CH4 per gram (fresh weight) of soil over 16 days of aerobic incubation at room temperature. The pH in microcosm materials remained acidic (decreased from initial 4.7 to 4.5). Protein extraction and

In previous comparisons of persistence to tumor necrosis factor α inhibitors (TNFis, a paucity of data for subcutaneous (SC golimumab was identified. The aim of this study was to conduct a systematic review of persistence to SC golimumab in clinical practice and contextualize these data with five-year persistence estimates from long-term open-label extension (OLE trials of SC TNFis in IMRDs.Patients and methods: PubMed, Embase, MEDLINE, and conference proceedings from European League Against Rheumatism (EULAR, American College of Rheumatology (ACR, and International Society for Pharmacoeconomics and Outcomes Research (ISPOR were searched. All studies on patients treated with SC golimumab for IMRD were included if they reported data on the persistence to golimumab.Results: Of 376 available references identified through the searches, 12 studies with a total of 4,910 patients met the inclusion criteria. Furthermore, nine OLE trials were available. Among the included studies from clinical practice, at six months, one year, two years, and three years, the proportion of patients persistent to treatment ranged from 63% to 91%, 47% to 80%, 40% to 77%, and 32% to 67%, respectively. In the four studies that included comparisons to other biologics, golimumab was either statistically noninferior or statistically superior to other treatments, an observation that was supported by indirect comparisons of unadjusted point

In the last few years, there have been an increasing number of reports about sterile intraocular inflammation and intraocular pressure elevations after intravitreal bevacizumab. In the following case series, we describe the clinical presentation and outcomes of ten consecutive cases of patients developing mild-to-severe sterile intraocular inflammation after intravitreal bevacizumab and their management. Methods: This report presents a retrospective case series. We reviewed the medical records of ten consecutive patients from a group of 46, in whom repackaged bevacizumab in individual aliquots from two vials from the same batch were used. All surgical procedures were performed using standard sterile techniques in the operating room. At each follow-up visit, patients underwent a complete ophthalmological examination including visual acuity assessment, intraocular pressure, biomicroscopy, and posterior fundus examination. Results: Ten patients presented sterile endophthalmitis with an onset time of 3.5±1.95 days. The clinical characteristics were mild pain, slight visual loss, conjunctival hyperemia, and various degrees of intraocular inflammation with microhypopyon. All cultures were negative.

    Full Text Available Resumen: Una lectura sobre los estudios narratológicos revela que el acto narrativo es un hecho consustancial al ser humano. “Somos el homo sapiens, porque somos el homo narrans”, diría el académico José María Merino (2002: 57. De las estructuras narrativas, el cuento oral tradicional se alza como la forma más antigua. Tan antigua y presente en todos los pueblos que componentes semánticos y formales se repiten en relatos de distintas culturas. Tales aspectos constituyen el objeto de análisis de este repertorio de cuentos fantásticos de Guinea Ecuatorial transmitidos en lengua española. En dicho entorno, el cuento oral fang se manifiesta como un arte viviente. No es un evento pensado sólo para niños; toda la comunidad participa de esta “fiesta” que se verá enaltecida por la presencia del canto. Dada la escasa proliferación de estudios del relato oral africano y en particular del guineano, se hace imperativo partir de estudios occidentales, lo cual nos desliza hacia el terreno del comparativismo. Sin embargo, no siempre dichos estudios son confirmados en esta investigación que concluye con las siguientes tesis: el criterio verdad y ficción al que se recurre para delimitar ciertas narraciones tradicionales europeas queda difuminado; uso irregular de las fórmulas de abertura y cierre; la asignación del fin lúdico de los cuentos fantásticos se acompaña del didáctico y la pretendida universalización del método estructuralista formal de Vladimir Propp, expuesta en Morfología del cuento (1987, se vislumbra inoperante, pues quedan reducidas las treinta y una funciones y la sucesión lineal de las mismas. Los temas y los motivos, arropados por el espíritu de la cultura donde emergen, son similares a los identificados en compilaciones españolas o internacionales. Finalmente, la naturaleza oral tradicional del repertorio queda patente a través de las nueve “Leyes Épicas” establecidas por Axel Orlik (1965: la Ley de

    Full Text Available A proposta deste dossiê temático teve sua origem em uma rede de cooperação entre pesquisadores radicados na França e no Brasil. O interesse teórico-metodológico que une os autores é delinear a emergência de diferentes formas de trabalho e emprego e sua teia de relações sociais, em uma abordagem comparativa e multidisciplinar. O presente dossiê versa sobre a precarização social: trata-se de relatar e refletir a respeito das relações de trabalho e emprego na atualidade em diferentes países, tendo como horizonte uma comparação Norte-Sul. A proposta aqui é a utilização do conceito de precarização social a partir da análise do próprio trabalho, das relações de emprego e suas institucionalidades. Precarização social é aqui interpretada como uma condição mais ampla de instabilidade e insegurança no trabalho. Se comumente a noção de trabalho precário se reporta ao trabalho desqualificado e inseguro, a noção de precarização aqui adotada remete a um processo social de institucionalização da instabilidade. O conceito coloca em perspectiva um duplo processo: um de precarização econômica que resulta da flexibilização salarial e das reestruturações produtivas, outro da institucionalização da precariedade, procedente das transformações legislativas referentes ao trabalho e à proteção social. Nosso argumento é que o conceito de precarização social permite ainda definir a institucionalização da instabilidade e configurar a sua justificação como se fosse um valor moral aceitável, a ser dirigido individualmente por cada ator na autogestão das carreiras e de sua inserção social O processo de precarização social alça o trabalho a uma dimensão de valor moral, o que nos permite inserir as questões relativas ao trabalho em uma teoria social de maior alcance. A teoria crítica de Axel Honneth parece ter uma notável contribuição a dar no processo de entendimento do paradoxo entre uma concep

    for constant volume replacement. Natural examples have fracture energy densities due to strain energy density of 100's of MPa [2]. Despite theory and observation, until now lab experiments on peridotite hydration and carbonation have not produced reaction-driven cracking. Slow kinetics and limited reactive surface area in low porosity samples may be the cause. Also, maximum stress may be limited by 'disjoining pressure', above which nano-films along grain boundaries collapse, and crystal growth essentially ceases [7]. To address these issues, we've begun experiments on analog materials with fast reaction rates, e.g., CaO + H2O = Ca(OH)2, to efficiently investigate the role of confining pressure and other factors on reaction-driven fracture events. Intriguingly, commercially available 'demolition mortar', largely CaO, produces stresses of 70 MPa or more around 1 inch bore holes at room T and P [8], even though there is a free surface at the top of the borehole, and hydration in a 'closed' system creates ~ 40% air-filled pore space.

    Ferrofluids are colloidal systems composed of a single domain of magnetic nanoparticles with a mean diameter around 30 nm, dispersed in a liquid carrier. Magnetic Co{sub (1-x)}Zn{sub x}Fe{sub 2}O{sub 4} (x=0.25, 0.50, 0.75) ferrite nanoparticles were prepared via co-precipitation method from aqueous salt solutions in an alkaline medium. The composition and structure of the samples were characterized through Energy Dispersive X-ray Spectroscopy and X-ray diffraction, respectively. Transmission Electron Microscopy (TEM) studies permitted determining nanoparticle size; grain size of nanoparticle conglomerates was established via Atomic Force Microscopy. The magnetic behavior of ferrofluids was characterized by Vibrating Sample Magnetometer (VSM); and finally, a magnetic force microscope was used to visualize the magnetic domains of Co{sub (1-x)}Zn{sub x}Fe{sub 2}O{sub 4} nanoparticles. X-ray diffraction patterns of Co{sub (1-x)}Zn{sub x}Fe{sub 2}O{sub 4} show the presence of the most intense peak corresponding to the (311) crystallographic orientation of the spinel phase of CoFe{sub 2}O{sub 4}. Fourier Transform Infrared Spectroscopy confirmed the presence of the bonds associated to the spinel structures; particularly for ferrites. The mean size of the crystallite of nanoparticles determined from the full-width at half maximum of the strongest reflection of the (311) peak by using the Scherrer approximation diminished from (9.5{+-}0.3) nm to (5.4{+-}0.2) nm when the Zn concentration increases from 0.21 to 0.75. The size of the Co-Zn ferrite nanoparticles obtained by TEM is in good agreement with the crystallite size calculated from X-ray diffraction patterns, using Scherer's formula. The magnetic properties investigated with the aid of a VSM at room temperature presented super-paramagnetic behavior, determined by the shape of the hysteresis loop. In this study, we established that the coercive field of Co{sub (1-x)}Zn{sub x}Fe{sub 2}O{sub 4} magnetic

    Full Text Available The present paper reports the synthesis and characterization of Ti doped ZrO2 nanophosphors. The effects of variable concentration of titanium on thermoluminescence (TL behaviour are studied. The samples were prepared by combustion a synthesis technique which is suitable for less time taking techniques also for large scale production for nano phosphors. The starting material used for sample preparation are Zr(NO33 and Ti(NO33 and urea used as a fuel. The prepared sample was characterized by X-ray diffraction technique (XRD with variable concentration of Ti (0.05–0.5 mol% there is no any phase change found with increase the concentration of Ti. Sample shows cubic structure and the particle size calculated by Scherer's formula. The surface morphology of prepared phosphor was determined by field emission gun scanning electron microscopy (FEGSEM technique for optimized concentration of dopant. The good connectivity with grains and the semi-sphere like structure was found by FEGSEM. The functional group analysis was determined by Fourier transform infrared (FTIR spectroscopic techniques. The prepared phosphor examined by thermoluminescence technique. For recording TL glow curve every time 2 mg phosphor was irradiated by UV 254 nm source and fixed the heating rate at 5 °C s−1. Sample shows well resolved peak at 167 °C with a shoulder peak at 376 °C. The higher temperature peak shows the well stability and less fading in prepared phosphor. Also the effect of Ti concentration at fixed UV exposure time was studied. The effect of UV exposure time and dose versus intensity plot was studied. Sample shows linear response with dose and broaden peak with high temperature shows the more stability and less fading in TL glow curve. The linear dose response, high stability and less fading phenomenon shows the sample may be useful for thermoluminescence dosimetry application. Trapping parameters are calculated for every recorded glow curve. The

    elevated temperatures resulting in Lu diffusing from high Lu regions after garnet formation, potentially leading to anomalously old ages (e.g., Ganguly et al., 2011). (3) The Lu-Hf system has a higher closure temperature than Sm-Nd (e.g., Scherer et al., 2001) and younger Sm-Nd ages could reflect a later start of their isotopic clocks. Based on our data, the first two explanations are unlikely. None of the Blue Ridge garnets have significant Lu/Hf or Sm/Nd zoning, which likely indicates equilibration of the garnets subsequent to their growth; differences in elemental partitioning during garnet growth cannot explain the age differences. The Lu-Hf ages, while much older than the Sm-Nd ages, are not anomalously old and agree with the time estimate of peak metamorphism in central Appalachians of 1028×9 Ma, based on zircon overgrowths (Carrigan et al., 2003). Therefore, we interpret the younger Sm-Nd ages as due to differences in closure temperatures; the Lu-Hf system closed soon after garnet growth at ~1024 Ma whereas Sm-Nd closed at ~ 970 to 930 Ma. These data require that the rocks remained at elevated temperatures and pressures for tens of millions of years, presumably deep within thickened crust, during the culmination of the Grenvillian orogeny.

(3) The Lu-Hf system has a higher closure temperature than Sm-Nd (e.g., Scherer et al., 2001; Smit et al., 2013) and younger Sm-Nd ages could reflect a later start of their isotopic clocks. Based on our data, the first two explanations are unlikely to generate large and systematic differences in the ages. None of the Blue Ridge garnets have significant Lu/Hf or Sm/Nd zoning, which likely indicates equilibration of the garnets subsequent to their growth; differences in elemental partitioning during garnet growth cannot explain the age differences. The Lu-Hf ages, while much older than the Sm-Nd ages, are not anomalously old and overlap with the timing of zircon growth. Ti-in-quartz thermometry performed on 7 samples yield a weighted average temperature of 828±54° C which broadly overlaps with estimates from the Ti-in-zircon thermometer by Tollo et al., (2010) of 740±40° C. Therefore, we interpret the younger Sm-Nd ages as due to differences in closure temperatures; the Lu-Hf system closed soon after garnet growth at ~1024 Ma whereas Sm-Nd closed at ~ 970 to 930 Ma. These data require that the rocks remained at elevated temperatures and pressures for tens of millions of years, presumably deep within thickened crust, during the culmination of the Grenvillian orogeny.

    categories based upon inclusion reaction history (5). In "best case" scenarios, zircon will be quasi-co-genetic with garnet formation and all phases will reflect the same Hf pool available during metamorphism. In this case, these "garnet" fractions may retain age information, but will yield underestimated Lu/Hf ratios that severely degrade isochron precision. However, "worst case" scenarios for these mixed-phase analyses will occur when zircon is inherited from prior events, such that garnet analyses represent two, unequilibrated Hf pools. Here, Lu/Hf isotopic analyses do not yield accurate age information on garnet growth as individual isotopic analyses reflect several, unrelated petrologic events. To avoid systematic introduction of errors of this type due to improper digestion procedures, garnet dissolutions should occur via low-pressure, hot-plate style digestion in Teflon beakers. Here, chemical conditions are unlikely to incorporate significant zircon-derived Hf within final solutions, ensuring that Lu/Hf ratios primarily reflect garnet compositions. 1.

Individual amino acids in the parts-per-trillion range were found in Antarctic ice samples collected from the surface of a meteorite collection area. The distinct amino acid and amine content of these samples indicates that further biomarker characterization of ice samples as a function of sampling location, depth, and structural features will be highly informative. The rapid sensitive analysis capabilities demonstrated here establish the feasibility of using the MOA to analyze the biomarker content of ice samples in planetary exploration. 1. Skelley, A.

    Internet addiction, defined as a maladaptive use of the Internet, is estimated to occur in 8-13% of college students (Chou, Condron, & Belland, 2005). It has become a serious mental health issue worldwide because addicts are impaired in various behavioral aspects including social interactions and academic performance (Morahan-Martin & Schumacher, 2000; Scherer, 1997; Young, 1998). Some researchers consider Internet addiction as a kind of behavioral addiction. However, there are few experimental studies on the cognitive functions of Internet addicts and limited data are available to compare Internet addicts with other addictive behaviors, such as drug abuse and pathological gambling. In the present study, we examined internet addicts' function of decision making. Two groups of participants, 42 Internet addicts (18~22 years old, 32 male, M = 19.79, SD = 1.14) and 42 controls (18~22 years old, 26 male, M = 19.71, SD = 1.13), were compared on the cognitive function and impulsivity by using a Chinese computerized versions of the IGT and Sensation Seeking Scale (SSS). In the IGT, subjects had to choose between four decks of cards. Unknown to the subjects, two piles offered larger short-term gains that are offset by greater risks of heavy losses, and hence were disadvantageous in the long run. The other two piles offered smaller short-term gains and a lower risk of loss that result in long-term maximization of the monetary payoff. The results of the present study showed that (1) compared with controls, sensation seeking of internet addicts was higher significantly, and internet addicts showed significantly higher scores on subscales of thrill and adventure seeking, disinhibition and boredom susceptibility, and they selected significantly less net decks in the Iowa Gambling Task. Furthermore, Internet addicts made no progress in selecting strategy along with the time course of the decision making. (2) reaction patterns for pure win-cards were consistent between

Combining this sequence with data from TG/DSC, we calculated the supersaturation of the solution with respect to each crystallizing phase as well as the associated crystallization pressure5. In situ environmental scanning electron microscopy (ESEM) complemented 2D-XRD data by giving high magnification images of crystallization and phase transitions during dissolution/precipitation cycles. These results give us a clear understanding of sodium sulfate behavior during evaporative crystallization. Further studies will examine different salts and different substrates. This research will help us to better understand the crystallization of salts and associated weathering in cultural heritage, natural environments and possibly, in other planetary bodies.

    elegant strategy for preparing multifunctional monoliths through spatially controlled surface functionalization.[9] Photochemical initiation affords spatial control over the reaction site, i.e. site-specific immobilization of ligands on the pore surface of the monolith. Hydrophobic and hydrophilic molecular entities were successfully grafted and the obtained monoliths were applied to electrochromatographic separation application under reversed-phase and hydrophilic interaction electrochromatography modes, respectively. The panel of successfully analyzed analytes ranges from hydrophobic polycyclic aromatic hydrocarbons to life markers such as amino acids and peptides. Our approach was extended to the local design of chelating interface for the site-specific immobilisation of gold nanoparticles. Taking advantage of the unique properties of supported nano-gold, it was possible to perform surface enhanced Raman spectroscopy (SERS) sensing of organic molecules at the sub-nanomolar level.

    The Latest Permian Extinction (LPE, ~252 million years ago) was a turning point in the history of life on Earth with a loss of ~96% of all marine species and ~70% of all terrestrial species. While, the event undoubtedly shaped the evolution of life its cause remains enigmatic. A leading hypothesis is that the global oceans became depleted in oxygen (anoxia). In order to test this hypothesis we investigated a proxy for marine oxygen levels (molybdenum isotopic composition) in shale across the LPE horizon located on the subtropical northwest margin of Pangea at that time. We studied two sedimentary records in the Sverdrup basin, Canadian High Arctic: Buchanan Lake (eastern Axel Heiberg Island; 79° 26.1'N, 87° 12.6'W), representing a distal deep-water slope environment, and West Blind Fiord (southwest Ellesmere Island; 78° 23.9'N, 85° 57.2'W), representing a deep outer shelf environment (below storm wave base). The molybdenum isotopic composition (δ98/95Mo) of sediments has recently become a powerful tool as a paleo-oceanographic proxy of marine oxygen levels. Sample preparation was carried out in a metal-free clean room facility in the isotope laboratory of the Department of Physics and Astronomy, University of Calgary, Canada, that is supplied by HEPA-filtered air. Molybdenum isotope ratios were determined on a Thermo Scientific multi-collector inductively coupled plasma mass spectrometer (MC-ICP-MS) with an uncertainty better than ±0.10o for δ98/95Mo values. Results from the Buchanan Lake section show a large shift in δ98/95Mo values from 2.02o to +2.23o at the extinction horizon, consistent with onset of euxinic conditions. In contrast, West Blind Fiord shales, representing the sub-storm wave base shelf environment, show little change in the molybdenum isotopic composition (1.34o to +0.05), indicating ongoing oxic conditions across the LPE (Proemse et al., 2013). Our results suggest that areas of the Pangea continental shelf (North West Pangea) experienced

    As the core value of modern societies, freedom constitutes the main aim of the social justice, and different understandings of freedom always lead to different theories of justice. In his Freedom' s Right, Axel Honneth explores the concept and history of negative freedom and reflexive freedom, and reveals their intrinsic defects. Then he suggests a project that can conquer these defects by Hegelian conception of social freedom. So-cial freedom, which preserves one' s freedom under the relation with others, needs the mutual recognition rela-tions among different individuals in itself; hence it requires the existence of normative practice institutions that can safeguard the mutual recognition relations. After his analyses of three domains of our lives:the personal rela-tions, the market economy and the public policy, Honneth shows the mutual recognition relations behind these social practices and presents a series of criticisms of actual lives based on these recognition relations, which con-stitute his main claims of social justice. Compared with John Rawls, who hopes to achieve the social justice by the equal distribution of social resources, Honneth attempts to achieve the social justice by his normative recon-struction of the mutual recognition relations implicit in our real lives and his criticisms of these relations. His the-ory is thus not only the criticism of the theory of justice, but also the critical theory of justice.%作为现代社会的核心价值,自由是社会正义旨在实现的主要目标,对自由的不同理解往往会产生不同的正义理论. 《自由的权利》中,霍耐特分别对消极自由和反思的自由进行了概念与历史的梳理,指出它们存在的根本问题,提出了用黑格尔式的社会自由来克服这些缺陷的构想. 社会自由是"在他人之中保持自我"的自由,它内在地需要一种相互承认的关系,并要求存在保障这种承认关系的规范性实践机制. 通过对现代社会

We tested the efficacy of a novel dual PI3K/mTOR inhibitor, NVP-BGT226 (BGT226, in two anaplastic large cell lymphoma cell lines in vitro and in vivo and performed an early response evaluation with positron emission tomography (PET imaging using the standard tracer, 2-deoxy-2-[18F]fluoro-D-glucose (FDG and the thymidine analog, 3'-deoxy-3'-[18F]fluorothymidine (FLT. Methods: The biological effects of BGT226 were determined in vitro in the NPM-ALK positive cell lines SU-DHL-1 and Karpas299 by 3-[4,5-Dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide assay, propidium iodide staining, and biochemical analysis of PI3K and mTOR downstream signaling. FDG-PET and FLT-PET were performed in immunodeficient mice bearing either SU-DHL-1 or Karpas299 xenografts at baseline and 7 days after initiation of treatment with BGT226. Lymphomas were removed for immunohistochemical analysis of proliferation and apoptosis to correlate PET findings with in vivo treatment effects. Results: SU-DHL-1 cells showed sensitivity to BGT226 in vitro, with cell cycle arrest in G0/G1 phase and an IC50 in the low nanomolar range, in contrast with Karpas299 cells, which were mainly resistant to BGT226.

  5. Astronomical dating in the 19th century

    Today astronomical tuning is widely accepted as numerical dating method after having revolutionised the age calibration of the geological archive and time scale over the last decades. However, its origin is not well known and tracing its roots is important especially from a science historic perspective. Astronomical tuning developed in consequence of the astronomical theory of the ice ages and was repeatedly used in the second half of the 19th century before the invention of radio-isotopic dating. Building upon earlier ideas of Joseph Adhémar, James Croll started to formulate his astronomical theory of the ice ages in 1864 according to which precession controlled ice ages occur alternatingly on both hemispheres at times of maximum eccentricity of the Earth's orbit. The publication of these ideas compelled Charles Lyell to revise his Principles of Geology and add Croll's theory, thus providing an alternative to his own geographical cause of the ice ages. Both Croll and Lyell initially tuned the last glacial epoch to the prominent eccentricity maximum 850,000 yr ago. This age was used as starting point by Lyell to calculate an age of 240 million years for the beginning of the Cambrium. But Croll soon revised the tuning to a much younger less prominent eccentricity maximum between 240,000 and 80,000 yr ago. In addition he tuned older glacial deposits of late Miocene and Eocene ages to eccentricity maxima around 800,000 and 2,800,000 yr ago. Archibald and James Geikie were the first to recognize interglacials during the last glacial epoch, as predicted by Croll's theory, and attempted to tune them to precession. Soon after Frank Taylor linked a series of 15 end-moraines left behind by the retreating ice sheet to precession to arrive at a possible age of 300,000 yr for the maximum glaciation. In a classic paper, Axel Blytt (1876) explained the scattered distribution of plant groups in Norway to precession induced alternating rainy and dry periods as recorded by the

    .Permafrost areas occupy 20-25% of the Earth and extend of 1 km depths. The total number of prokaryotes and their biomass in cold regions are estimated to be 1 x 1030 cells and 140 x1015 g of C, respectively. Thus these environments serve as a reservoir of microbial and biogeochemical activity, which is likely to increase upon thawing. We are currently performing long-term thawing experiments at 4o C on 18, geochemically well-characterized, 1 meter long, intact cores consisting of active-layer (0-70 cm depth) and permafrost, collected from a 7 meter diameter ice-wedge polygon located at the McGill Arctic Research Station on Axel Heiberg Island, Nunavut, Canada. The organic carbon content of these cores averages ~1% at depth but increases to 5.4% in the top 10 cm. The cores were subdivided into four treatment groups: saturated cores (thawed while receiving artificial rain), drained cores (being thawed under natural hydrological conditions), dark cores (thawed under natural hydrological conditions with no light input) and control cores (maintain permafrost table at 70 cm depth). Over the course of 10 weeks the cores were progressively thawed from -4oC to 4oC from the top down to simulate spring thaw conditions in the Arctic. The temperatures at 5 cm, 35 cm, 65 cm, and below the permafrost table in the core were recorded continuously. Pore water and gas samples from 4 depths in each core were collected every two weeks and analyzed for pH, anions, cations, H2, CH4, CO, O2, N2, CO2 and δ13C of CO2. Headspace gas samples were collected weekly and analyzed for the same gases as the pore gases. Sediment sub-samples from the 4 depths were collected and total community genomic DNA (gDNA) was isolated using FastDNA SPIN kit followed by Qiagen column purification. The average yield of gDNA was ~3.5 μg/g of soil for the upper 5 cm active layers and decreased to ~1.5 μg/g of soil in the permafrost.

    Axel Liebscher1, Magdalena Scheck-Wenderoth1 and the GeoEn Research Group1, 2,3 1 Helmholtz Centre Potsdam GFZ German Research Centre for Geosciences, Potsdam, Germany 2 University Potsdam, Germany 3 BTU Cottbus, Germany One of the pressing challenges for the 21st century is a secure, sustainable and economical energy supply at simultaneous mitigation of its climate impact. Besides a switch to renewable energy resources, the exploration and exploitation of new, unconventional energy resources will play a major role as will the further use of fossil fuels. With the switch to renewable energies the question of geological energy storage will become an important topic whereas further use of fossil fuels requires strategies like CCS to reduce its negative climate impacts. These different aspects of geo-energy make complementary or competitive demands on the subsurface and its use. It is therefore essential to treat the subsurface as a geo-resource of its own right. So far, geo-resource related research has often focused on specific resource systems, e.g. ore forming systems, hydrocarbon systems or geothermal systems, providing results largely applicable only to the restricted range of physicochemical properties of the respective geo-resource systems. However, with the increasing use of the subsurface as important geo-resource, the different geo-resource systems tend to overlap and interact and also become much more complex due to the additional use or presence of artificial and technical matter, as is the case in geological CO2 storage. On the other hand, the combined use of the subsurface for different purposes may also create synergetic effects. GeoEn is a joint research project explicitly addressing the fundamental questions related to the sustainable and holistic use of the geo-resource subsurface with a special focus on geo-energy. Project partners are the German Research Centre for Geosciences (GFZ), the University of Potsdam (UP) and the Brandenburg University of

    Although many studies found that in general negative attitudes toward old people were widespread, in recent research there were evidences showing the negative implicit attitudes toward old people had context effect. Old people were regarded as warm but low-competent, convinced in a stereotype content model. However some researchers discovered that people are more like considering old people having connections with more professional career. So in this study we tried to find out the implicit attitude toward old people from young undergraduate students in the contexts of career, virtue, family and so on.There were three experiments in this study. Sixty college students participated in the first experiment, and they had to decide as fast as possible whether the target after a youthful prime or a elderly prime formed a Chinese word or not. Experiment II and III applied a newly developed research method: the Affect Misattribution Procedure (AMP) and the fundamental principle of the method was projection. Its hypnosis was people would feel pleasant after they saw a positive picture, so that they were more likely to judge the ambiguous symbol to be more pleasing than average. Both experiments added context factor into the typical method of the AMP, and they were similar to the AMP used by Scherer & Lambert (2009). The second experiment used words as primes, which was different with the typical AMP in which pictures were used as primes. 126 and 57 undergraduate students participated in the experiment II and III respectively. The aim of the first experiment was to discover whether people thought the old were more professional than the youth. The experiment assumed that old people had been more closely connected to the concept of "professional" "experienced" and so on. So the average reaction time for professional words after elderly primes would be shorter than after youthful primes. But the result didn't show a remarkable difference in terms of the two reaction times. This

    Full Text Available The cassava is presented as an important stach source, mainly in the tropics. The bacteriosis disease caused by Xanthomonas axonopodis p.v. manihots is the most important disease of this culture and its damage can achieve 30% of the production, or even more. This work objectified to evaluate, in green house condition the reaction of “mandioca mansa” and the “mandioca brava” cassava’s germoplasma to the two isolates of Xanthomonas axonopodis p.v. manihots. Trials were developed at the Instituto de Ciências Agrárias da Universidade Federal de Uberlândia. The plants had been inoculated by seasor’s cuttings of three central leaflets in three completely opened new leaves, following by insertion of a little wood stick at the oldest leaf’s axel, using a bacterial suspension at 2x109u.f.c. mL-1. The inoculation happened at the 42nd day after planting and the evaluation at the 41st day after inoculation. The evaluation criteria were: notes of visual symptoms in the aerial part, percentages defoliation and systemic infection of the stalk. The results showed the efficiency of the evaluation criteria applied at this work for the isolates virulence study. The Uberlândia isolate was more virulent to “mandioca mansa” cassava cultivars and the Lavras isolate was more virulent to “mandioca brava” cassava cultivars. That indicates the need of using isolates from the region where the germoplasm will be cultivated. Considering the germoplasm resistance reaction analysis, both the sistemic infection precentage and the defoliation criteria presented as very effective. Oustanding behavior was observed for the Vassoura, Amarela, Vermelha and Castelinho cultivars and for the CPAC88-11 clone.A mandioca apresenta-se como importante fonte de carboidratos, principalmente nos trópicos.

    Arctic regions are expected to experience temperature increases of >4° C by the end of this century. This warming is projected to cause a drastic reduction in the extent of permafrost at high northern latitudes, affecting an estimated 1000 Pg of SOC in the top 3 m. Determining the effects of this temperature change on CO2 and CH4 emissions is critical for defining source constraints to global climate models. To investigate this problem, 18 cores of 1 m length were collected in late spring 2011 before the thawing of the seasonal active layer from an ice-wedge polygon near the McGill Arctic Research Station (MARS) on Axel Heiberg Island, Nunavut, Canada (N79°24, W90°45). Cores were collected from acidic soil (pH 5.5) with low SOC (~1%), summertime active layer depth between 40-70 cm (2010-2013), and sparse vegetation consisting primarily of small shrubs and sedges. Cores were progressively thawed from the surface over the course of 14 weeks to a final temperature of 4.5° C and held at that temperature for 15 months under the following conditions: in situ water saturation conditions versus fully water saturated conditions using artificial rain fall, surface light versus no surface light, cores from the polygon edge, and control cores with a permafrost table maintained at 70 cm depth. Core headspaces were measured weekly for CO2, CH4, H2, CO, and O2 flux during the 18 month thaw experiment. After ~20 weeks of thawing maximum, CO2 flux for the polygon edge and dark treatment cores were 3.0×0.7 and 1.7×0.4 mmol CO2 m-2 hr-1, respectively. The CO2 flux for the control, saturated, and in situ saturation cores reached maximums of 0.6×0.2, 0.9×0.5, and 0.9×0.1 mmol CO2 m-2 hr-1, respectively. Field measurements of CO2 flux from an adjacent polygon during the mid-summer of 2011 to 2013 ranged from 0.3 to 3.7 mmol CO2 m-2 hr-1. Cores from all treatments except water saturated were found to consistently oxidize CH4 at ~atmospheric concentrations (2 ppmv) with a maximum

    Astronomers studying gas clouds in the famous Whirlpool Galaxy have found important clues supporting a theory that seeks to explain how the spectacular spiral arms of galaxies can persist for billions of years. The astronomers applied techniques used to study similar gas clouds in our own Milky Way to those in the spiral arms of a neighbor galaxy for the first time, and their results bolster a theory first proposed in 1964.

Also known as M51, it is seen nearly face-on from Earth and is familiar to amateur astronomers and has been featured in countless posters, books and magazine articles. "This galaxy made a great target for our study of spiral arms and how star formation works along them," said Eva Schinnerer, of the National Radio Astronomy Observatory in Socorro, NM. "It was ideal for us because it's one of the closest face-on spirals in the sky," she added. Schinnerer worked with Axel Weiss of the Institute for Millimeter Radio Astronomy (IRAM) in Spain, Susanne Aalto of the Onsala Space Observatory in Sweden, and Nick Scoville of Caltech. The astronomers presented their findings to the American Astronomical Society's meeting in Denver, Colorado. The scientists analyzed radio emission from Carbon Monoxide (CO) molecules in giant gas clouds along M51's spiral arms. Using telescopes at Caltech's Owens Valley Radio Observatory and the 30-meter radio telescope of IRAM, they were able to determine the temperatures and amounts of turbulence within the

    Full Text Available Arabesk music is an endemic genre to Turkey. Theoretically, it may be deemed to include depressive feelings of grief, an intense level of sadness and anger. However, in practice there has been no empirical research to date concerning what emotion the music contains or inspires in listeners. In this study, we examined the level of felt and perceived emotions in arabesk music; at what level lyrics, tempo, and maqam have an impact on the feeling and perceiving; and which individual/social factors have the biggest effect on preference arabesk. By the results obtained, albeit relative, we aimed to deduct a profile of emotion and empirically evaluate the musical, individual and social dimensions' impact on the reason why arabesk is preferred.  A total of (n=146 participants ranged from 15-49 year old (28% female (72% and men (n = 75 arabesk lovers and (53% female (47% and male (n = 71 music students. Both groups were given questionnaires prepared for them. Then, in five different maqams and tempos, eight different arabesk songs were played for participants. In the evaluation process, arabesk lovers were requested to grade their feelings and music students were requested to grade their perceptions in a 5-point Likert scale (1 = felt nothing, perceived nothing; 5 = felt a lot, perceived a lot. Geneva Emotion Music Scale, GEMS, which was developed by Zentner Grandjean & Scherer (2008, was used to evaluate the types of emotion. The findings obtained, as predicted, showed that the sadness factor is very distinctive in almost all instances. However, a feeling of sadness wasn’t found at a level predicted among arabesk lovers. Moreover, it was understood that together with the sense of sadness and tension, the music induced intense nostalgia, tenderness and peacefulness; and in a very low rate, it caused power, wonder and a transcendence factor. Also, statistically, there were significant differences between arabesk lovers’ feelings and music students

    realizations of voltage, resistance and current to test their consistency. Active research into this 'metrological triangle' is underway and, at present, there is no evidence to indicate a discrepancy at any level. However, work is continuing on current sources which utilize a countable flow of electrons (the electric current produced is proportional to ef, f being the operating frequency of the device), but the work has some way to go before the question of consistency can be resolved at levels approaching 1 part in 109. In this special feature, Scherer and Camarota review the state-of-the-art of metrological triangle experiments and Devoille et al report on the status of the metrological triangle experiment at the Laboratoire National de Métrologie et d'Essais (LNE), France. The availability of precise representations of the volt and the ohm based on quantum mechanics has enabled the watt balance, an apparatus which relates electrical and mechanical power, to link the kilogram to the Planck constant. This has paved the way for the proposed redefinition of the kilogram, the last artefact standard in the SI, in terms of a fixed value of the Planck constant. In the past few years a number of papers, e.g. [2, 3], have been published describing the working principles of the watt balance and the characteristics of the existing implementations of the experiment. The measurements of the principal quantities—mass, velocity, gravitational acceleration, resistance and voltage—are reasonably well documented but the ultimate precision of the apparatus depends on a number of techniques that are required to eliminate second-order effects. In this special feature, Robinson provides details of these general alignment techniques with special reference to the NPL Mark II watt balance. Acknowledgments We would like to thank the authors for supporting the special feature with their excellent contributions; the guardians of the quality of a scientific paper, the referees, for their valuable

    Western and Soviet laser cooling communities. In neutral Finland, accessible to both parties, he organized informal workshops that crucially sped the development of laser cooling. The importance of these meetings is highlighted in Bill Phillips' Nobel lecture in 1997 [6]. However, as the emphasis in laser cooling moved from a semiclassical description to quantum theory, Stig started to look for new avenues of research. My contact with Stig came when I went to see him for an MSc thesis topic. This involved polarization spectroscopy and modelling of an experiment performed by the laser spectroscopy group (Birger Ståhlberg) at the University of Helsinki. Without knowing anything about quantum optics I then found myself immediately in one of the Finnish-Soviet workshops on quantum electronics in the small town of Porvoo slightly east of Helsinki. There I met people like Juha Javanainen, Peter Knight, Axel Schenzle and Vladimir Chebotayev, and my own career in quantum optics began, working on the mathematics of the Landau-Zener model and how to apply it and other such models in molecular excitation by femtosecond pulses for my PhD thesis. This work was done together with Barry Garraway, who was a postdoc in Helsinki in the early 1990s. The Finnish-Soviet meetings continued for a while, and in 1990 we even got to travel to Novosibirsk (and back, too). During its existence (1964-1996), the Research Institute of Theoretical Physics (TFT) had a tremendous impact on physics in Finland. Short and long stays by visitors provided a unique and high-level environment for local researchers, the research fields covered a wide range of physics, and for many Finns returning from abroad it provided a place to stay until something more permanent turned up. Thus many researchers who later became professors had, at some point in their career, a connection with TFT. As a director Stig was very broad-minded and without this the happy atmosphere of TFT could not have existed. In the 1980s young

At that level, the Earth rotation models are consistent with the general relativity framework recommended by the IAU and considered in this book. The chapter presents practical algorithms for implementing the recommended models. The appendices to the book contain a list of astronomical constants and the original text of the relevant IAU resolutions adopted by the IAU General Assemblies in 1997, 2000, 2006, and 2009.

    The Second International Conference and Advanced School 'Turbulent Mixing and Beyond', TMB-2009, was held at the Abdus Salam International Centre for Theoretical Physics, (ICTP), Trieste, Italy on 27 July-7 August 2009. TMB-2009 united over 180 participants ranging from students to members of the National Academies of Sciences and Engineering, and including researchers at experienced and early stages of their carriers from leading scientific institutions in academia, national laboratories, corporations and industry worldwide. Responding to the community's inquiry and reaffirming the practices established at TMB-2007, two Round Tables were organized for the participants of TMB-2009 on 30 July 2009 and 6 August 2009 in the Oppenheimer Room at the Centre. The goals of the Round Tables were to encourage the information exchange among the members of the interdisciplinary and international TMB community, promote discussions regarding the state-of-the-art in TMB-related scientific areas, identify directions for frontier research, and articulate recommendations for future developments. This article is a summary of the collective work of the Round Table participants (listed alphabetically below by their last names), whose contributions form its substance and, as such, are greatly appreciated.
