  1. L'impact de la contrainte carbone sur le secteur électrique

    OpenAIRE

    2011-01-01

    This paper asks whether the European Union Emission Trading Scheme (EU ETS) provides economic incentives to reduce carbon emissions. If so, electricity producers should include the price of carbon in their cost functions. After identifying different sub-periods of the EU ETS during its pilot phase (2005-2007), we model day-ahead electricity prices in France and Germany and look at their volatility around the fundamentals white evaluating the correlation between electricity prices in the two c...

  2. Interprétation cohérente du coefficient de Poisson négatif rapporté dans des multicouches métalliques : rôle du paramètre libre de contrainte

    étermination expérimentale par la méthode des sin^2Psi de la référence (paramètre libre de contrainte) servant de base au calcul des déformations. Nous montrons alors que l'introduction du paramètre du matériau massif comme référence est une hypothèse irréaliste dans le cas des films minces et multicouches (W et Ag/Ni) qui peut conduire à des résultats erronés et en total désaccord avec ceux obtenus par d'autres techniques. Ainsi, l'anomalie élastique au niveau du coefficient de Poisson soulevée par certains auteurs dans la littérature n'est pas imputable à la structure elle-même mais à l'analyse qui est faite des données expérimentales obtenues par diffraction des rayons X.

  3. La contrainte client

    Full Text Available Cet article montre que le contact client a beau être ambivalent, dans la mesure où il est à la fois source de contrainte et de reconnaissance, dans certains cas, comme celui des caissières, il constitue avant tout une contrainte, en ce que les clients contrôlent le travail qui s’opère « sous leurs yeux », tandis que, dans d’autres cas, comme celui des kinésithérapeutes, il contribue avant tout à donner du sens au travail et, par là, à susciter l’engagement des travailleurs. L’article souligne ainsi combien la contrainte client revêt des modalités différentes selon la configuration, spatiale et temporelle, dans laquelle se déroule la relation de service, et le différentiel de compétences entre les protagonistes engagés dans cette relation.The client constraint. A comparative analysis of cashiers and physiotherapistsThis article shows that despite the ambivalence of client contact, insofar as it is both a source of constraint and recognition, in some cases, as the ones of cashiers, it isprimarily a constraint: clients control the work that takes place “before their eyes”, whereas in other cases – as in the ones of physiotherapists – it contributes to give meaning to work and, thereby, to arouse the commitment of workers. The article highlights how the client constraint takes on different forms depending on thespatial and temporal configuration where the service relation runs, and the skills differential between the protagonists involved in this relation.El apremio de los clientes. Análisis comparativo entre las cajeras de supermercado y los kinesiterapeutasEn este artículo se demuestra que aunque el contacto con los clientes puede ser percibido como agradable, en realidad en la mayoría de los casos el cliente es percibido como un peso puesto que estos « controlan » visualmente el trabajo de las cajeras mientras que en otras profesiones como es el caso de los kinesiterapeutas la presencia del paciente

  14. Contraintes de taille dans les mots composés : quand la phonologie entre en concurrence avec les contraintes morphologiques

    Directory of Open Access Journals (Sweden)

    Villoing Florence

    2012-07-01

    Full Text Available Cette communication porte sur les contraintes phonologiques qui pèsent sur la formation des mots construits dans le cadre théorique de la morphologie lexématique (Anderson 1992, Aronoff 1994, Fradin 2003. En étudiant les données du français, les travaux de Lignon (à paraître, Plénat (2009 & Roché (2003 ont montré que des contraintes de taille étaient à l’œuvre dans plusieurs constructions morphologiques. L’objectif de cet article est d’étudier cette hypothèse sur les mots composés Verbe-Nom du français (Villoing 2009. L’analyse quantitative des données du corpus montre clairement que les verbes des mots composés VN du français sont soumis à des contraintes de taille et doivent répondre au format d’un monosyllabe. La contrainte pèse moins lourdement sur les noms qui parviennent à s’imposer plus facilement que les verbes avec une taille supérieure. Cependant, la majorité des mots composés VN tend à ne pas dépasser trois syllabes (leur format optimal étant de deux ou trois syllabes, révélant ainsi l'influence des contraintes de taille sur le mot composé lui-même. La mise au jour de ces contraintes permet d'expliquer l’absence de certains verbes dans le corpus de composés VN, répondant pourtant bien aux propriétés sémantiques attendues : les verbes construits par affixation (absence de suffixés en -iser, -ifier; très rares cas de préfixés, les verbes du 2ème groupe, les verbes de taille supérieure à trois syllabes. En outre, cet article met au jour un cas de concurrence entre contrainte morphologique et contrainte phonologique au sein d'une construction morphologique, et montre comment la première l'emporte sur la dernière, bien que la contrainte phonologique contraigne fortement le choix du verbe et du nom de base. Il donne également à voir comment la contrainte phonologique parvient néanmoins à influencer le choix de bases sémantiquement peu conformes aux attentes de la règle.

    CERN Document Server

    AUTHOR|(CDS)2091894; Giovinazzo, Jérôme

    Les études de la radioactivité bêta dans les milieux nucléaires permettent en partie de participer à la détermination d’un des paramètres qui décrit l'interaction faible (la constante de couplage vectoriel). Pour cela, de nombreuses mesures permettent déjà d’atteindre de grandes précisions sur ce paramètre pour un grand nombre de noyaux des transitions bêta super-permise. Cependant, pour le carbone 10, l'incertitude relative du rapport d'embranchement reste encore élevée par rapport aux autres noyaux pères avec une valeur de l’ordre de 0,13 %. Ceci est dû à l’énergie du photon émis par l’état 0+ du noyau fils qui est de 1021,6 keV, c’est-à-dire proche de l’énergie d’empilement de deux signaux de photons de 511 keV. En mai 2015, notre groupe a réalisé, à ISOLDE au CERN, une expérience afin de mesurer très précisément cette transition. Pour produire le carbone 10,nous avons réalisé des réactions nucléaires qui produisaient en grandes parties les noyaux d’inté...

    2018-01-01

    Guides to neuropsychological assessment emphasize the importance of establishing rapport; however, there has been a minimal amount of empirical investigation of the impact of rapport on neuropsychological test performance. In this experiment, participants (N = 98) were randomly assigned to take neuropsychological tests in either a high or low rapport condition. Results showed that we were able to manipulate the level of rapport and that the level of rapport had a significant effect on the Grooved Pegboard Test and the Controlled Oral Word Association Test, with other tests nearing statistical significance. These results suggest that the level of rapport may affect neuropsychological test performance.

  10. Stress-Induced Seismic Anisotropy Revisited Nouveau regard sur l'anisotropie sismique induite par les contraintes

    ellipsoïdale, pour tout degré d'anisotropie. Par exemple, les sources ponctuelles engendrent des fronts d'onde qP de forme ellipsoodale. Ce résultat est général et est absolument indépendant du modèle de roche, c'est-à-dire indépendant des causes de la non-linéarité, pour autant que les hypothèses de départ soient vérifiées. Ceci constitue le principal résultat de cet article. Thurston (1965 a remarqué, vis-à-vis des propriétés élastiques, qu'un milieu élastique initialement isotrope, quand il est soumis à des contraintes non isotropes, n'est jamais tout à fait équivalent à un cristal anisotrope non soumis à des contraintes. Par exemple, les composantes du tenseur d'élasticité du milieu sous contrainte ne présentent pas la symétrie habituelle vis-à-vis de la permutation des indices. Ceci interdit l'emploi de la notation de Voigt sur les indices contractés. Toutefois, si l'amplitude des composantes du déviateur de contrainte est petite par rapport aux modules d'onde, ce qui est toujours vérifié sur le terrain en exploration sismique, l'équivalence parfaite est rétablie. Sous cette condition, les 9 rigidités élastiques C'ij (en notation contractée d'un solide initialement isotrope, soumis à une contrainte triaxiale, sont toujours liées par les 3 conditions ci-après d'ellipticité dans les plans de coordonnées associés aux directions propres de la précontrainte statique.

    2012-07-01

    Full Text Available L'objet de ce travail est de comprendre les processus phonologiques qui structurent le langage : pathologique ou non. Notre approche apparie phonologie et aphasiologie. Nous proposons ici une analyse de ces processus phonologiques à travers l'étude des groupes consonantiques dans les structures syllabiques dont ils dépendent. Le cas des clusters apparaît essentiel dans cette problématique. Cet objet n'est que trop peu exploité dans les travaux aphasiologiques alors qu'il s'avère central dans les approches phonologiques par les problèmes représentationnels qu'il pose : relations ou absence de relations entre les consonnes, hétérosyllabicité ou ambisyllabicité. Notre étude prend en compte : - une dimension segmentale : à travers la notion de complexité, - une dimension syllabique : par les relations de gouvernement imposées sur les représentations phonologiques. Nous postulons que ce n'est qu'en considérant l'interrelation de ces dimensions que l'on peut produire une explication des désordres phonologiques observés en pathologie et montrer que des régularités émergent. Dans cet article, nous exposons les traitements proposées à l'aphasie à travers deux cadres phonologiques : la Théorie de l'Optimalité [OT] et la Théorie des Contraintes et des Stratégies de Réparation [TCSR]. Il s'agit d'observer les apports et limites rencontrés par ces modèles. Ensuite, à partir de la Phonologie du Gouvernement, cadre dans lequel nous nous situons, depuis [KLV : 1985] jusqu'à [Scheer : 2010], nous analysons les données et exposons une explication des phénomènes tant au niveau segmental que syllabique.

    The general objective of this project was to contribute to the evaluation of land use and management impacts on C sequestration and nitrogen dynamics in soils. The land used through the presence/absence of crops and their species, and the land management through tillage, localisation of crop residues, fertilizer applications,... are important factors that affect the dynamics of organic matters in soils, particularly the mineralization of C and N, the losses to the atmosphere and hydrosphere, the retention of carbon into the soil. This project was conducted by four research groups, three of them having expertise in nutrient cycling of three major agro-ecosystems (arable crops, grasslands, forests) and the fourth one having expertise in modelling long term effects of land use on C storage into the soils. Within this common project one major objective was to better understand the fate of plant litter entering the soil either as above litter or as root litter. The focus was put on two factors that particularly affect decomposition: the initial biochemical quality of plant litter, and the location of the decomposing litter. One innovative aspect of the project was the use of stable isotope as {sup 13}C for carbon, based on the use of enriched or depleted {sup 13}C material, the only option to assess the dynamics of 'new' C entering the soil on the short term, in order to reveal the effects of decomposition factors. Another aspect was the simultaneous study of C and N. The project consisted in experiments relevant for each agro-ecosystem, in forest, grassland and arable soils for which interactions between residue quality and nitrogen availability on the one hand, residue quality and location on the other hand, was investigated. A common experiment was set up to investigate the potential degradability of the various residue used (beech leaf rape straw, young rye, Lolium and dactylic roots) in a their original soils and in a single soil was assessed.

    Sharing Economy platforms enable a close physical interaction among strangers by mediating goods and services owned or provided by individuals. This close physical interaction is an inherent part of the service experience, is highly individual and thus can hardly be evaluated beforehand. This gives...... rise to a novel type of service uncertainty that we term as rapport uncertainty. Building on the hierarchical decomposition of service quality, we construct an uncertainty model that encompasses three uncertainty categories consumers face when sharing a resource: rapport, technical, and environment...... uncertainty. Our empirical study in a ride sharing context reveals that rapport uncertainty differs from other categories of uncertainty and significantly reduces the intention to transact with a service provider. Our findings illustrate how the concept of uncertainty must be extended to reflect the nature...

    Patient-centred consulting is at the heart of modern medicine, and training programmes now routinely highlight a range of communication skills that enhance the doctor-patient relationship. The present pilot study focuses on the central role played by empathic skills in developing rapport and shared understanding, as captured in a new model developed by the authors. The specific aim of the study was to evaluate the potential of a short-term training programme using this model to improve rapport-related behaviour in general practitioner (GP) trainees. In a quasi-experimental study, 37 GP trainees from schemes in central England (the training group) participated in a training programme based around a new model of therapeutic rapport, with pre- and post-training analysis of relevant knowledge-based, affective and behavioural outcomes. A control group of ten GP trainees, from schemes in a comparable UK medical deanery, took no part in the training programme but were involved in all pre- and post-training analyses. The training group demonstrated significant increases in rapport-related knowledge and all three affective dimensions (attitudes, confidence and motivation); there was a similar finding in terms of 'positive engagement' and all expert-rated aspects of rapport-related behaviours. The control group showed no comparable improvement in any area, and recorded a significant drop in demonstration of positive engagement behaviours. The significant improvement in rapport-related knowledge, attitudes and behaviour after training, and the lack of any comparable change in the control group, gives some support to the suggestion that the module (and the model that underpinned it) may have triggered such an impact independent of ongoing experience or other educational activities.

    Physicians' negative attitudes toward patients with obesity are well documented. Whether or how these beliefs may affect patient-physician communication is unknown. To describe the relationship between patient body mass index (BMI) and physician communication behaviors (biomedical, psychosocial/lifestyle, and rapport building) during typical outpatient primary care visits was aimed. Using audio-recorded outpatient encounters from 39 urban primary care physicians (PCPs) and 208 of their patients, the frequency of communication behaviors using the Roter Interaction Analysis System was examined. The independent variable was measured; patient BMI and dependent variables were communication behaviors by the PCP within the biomedical, psychosocial/lifestyle, and rapport building domains. A cross-sectional analysis using multilevel Poisson regression models to evaluate the association between BMI and physician communication was performed. PCPs demonstrated less emotional rapport with overweight and obese patients (incidence rate ratio, IRR, 0.65, 95%CI 0.48-0.88, P = 0.01; IRR 0.69, 95%CI 0.58-0.82, P rapport in primary care visits with overweight and obese patients may weaken the patient-physician relationship, diminish patients' adherence to recommendations, and decrease the effectiveness of behavior change counseling.

    2017-08-09

    Rapport is established at the first meeting between the patient and nurse, and is developed throughout the therapeutic relationship. However, challenges can arise during this process. Initially, nurses can establish trust with the patient through the questions they ask, however, as care progresses, the nurse will be required to demonstrate a commitment to maintaining the patient's psychological well-being. When the therapeutic relationship ends, the nurse should assist the patient to assess progress and plan the next stage of recovery. This article provides three reflective exercises using case study examples to demonstrate how rapport is developed and sustained. Evidence is provided to identify why challenges arise in the therapeutic relationship and how the nurse can ensure they provide care that the patient regards as genuine.

  11. Revenge versus rapport: Interrogation, terrorism, and torture.

    2017-04-01

    This review begins with the historical context of harsh interrogation methods that have been used repeatedly since the Second World War. This is despite the legal, ethical and moral sanctions against them and the lack of evidence for their efficacy. Revenge-motivated interrogations (Carlsmith & Sood, 2009) regularly occur in high conflict, high uncertainty situations and where there is dehumanization of the enemy. These methods are diametrically opposed to the humanization process required for adopting rapport-based methods-for which there is an increasing corpus of studies evidencing their efficacy. We review this emerging field of study and show how rapport-based methods rely on building alliances and involve a specific set of interpersonal skills on the part of the interrogator. We conclude with 2 key propositions: (a) for psychologists to firmly maintain the Hippocratic Oath of "first do no harm," irrespective of perceived threat and uncertainty, and (b) for wider recognition of the empirical evidence that rapport-based approaches work and revenge tactics do not. Proposition (a) is directly in line with fundamental ethical principles of practice for anyone in a caring profession. Proposition (b) is based on the requirement for psychology to protect and promote human welfare and to base conclusions on objective evidence.

  12. BECCS as a climate measure. A report on carbon dioxide storage from biomass in a Swedish-Norwegian perspective; BECCS som klimataatgaerd. En rapport om koldioxidlagring fraan biomassa i ett svensk-norskt perspektiv

    As the economic costs for combating the threat of climate change are considerable, accurate priorities have to be set and economic efficiency must be sought. On this basis, this report aims at examining the Swedish and Norwegian opportunities and potential for geologic storage of carbon dioxide from biomass, or BECCS (Bio Energy with Carbon Capture and Storage). So-called biogenic carbon dioxide is part of the renewable carbon cycle. Carbon dioxide is extracted from the atmosphere into trees and crops as they grow, and is released when they are combusted or decompose. Therefore, biogenic carbon dioxide does not contribute to the increase of greenhouse gases in the atmosphere. On the contrary, these emissions may become part of the solution to the climate problem. When carbon dioxide that has been captured from the atmosphere by biomass is stored geologically, a flow of carbon from the atmosphere into the underground is created. With a scientific term, this is called negative emissions, or permanent carbon dioxide sinks. Since we already today have a level of 390 ppm of carbon dioxide in the atmosphere, and this level is rising by 2 ppm per year, negative emissions are vital if we are to achieve climate targets such as 350 or 400 ppm. Due to the large amount of biomass that is processed in the pulp industry as well as the use of biomass for energy production, there are several and large point sources of biogenic carbon dioxide emissions in Sweden. The 61 largest Swedish plants are together emitting more than 31 million tons of biogenic carbon dioxide per year. In Norway, these industries are significantly smaller with the major point emissions of biogenic carbon amounting to less than 2 million tons per year. Because of this the continued analysis focuses on Swedish emissions. However, there are very good opportunities for carbon dioxide storage in the Norwegian part of the North Sea. This is not the case in Sweden. Suitable conditions for carbon dioxide storage are

  14. Examining the positive effects of rapport building: when and why does rapport building benefit adult eyewitness memory?

    Science.gov (United States)

    Kieckhaefer, Jenna Mitchell; Vallano, Jonathan Patrick; Schreiber Compo, Nadja

    2014-01-01

    Most investigative interviewing protocols recommend building rapport with cooperative adult witnesses to increase the accuracy of their reports. Although a few recent studies support the benefits of rapport building on adult witness recall, no study has examined whether the timing of rapport in relation to post-event misinformation affects recall accuracy, and whether these effects are related to witness anxiety levels throughout the interview. The present study provided two hundred and thirty-three undergraduates with a videotaped mock crime followed by building high or low rapport either before or after they received post-event misinformation. All witnesses were then interviewed about the mock crime. Results indicated that high rapport before misinformation increased the amount of accurate information reported in a subsequent witness interview compared to low rapport. However, these recall benefits were not due to a reduction in anxiety. Theoretical implications and practical recommendations for police interviewing practices are discussed.

    Les contraintes résiduelles s'introduisent lors de l'ingénierie des composants au cours de leur fabrication et également au cours de leur utilisation. Elles sont importantes parce qu'elles peuvent avoir des magnitudes proches de la limite apparente d'élasticité et peuvent par conséquent affecter considérablement la performance et la durée de vie des composants. Les ingénieurs concepteurs doivent être en mesure de calculer et de mesurer les champs de contraintes résiduelles afin de s'assurer de l'intégrité des composants. Cet article décrit les techniques expérimentales utilisées pour déterminer des champs de contraintes résiduelles en faisant référence plus précisément à la diffraction des neutrons et à la diffraction des rayons X obtenus par synchrotrons. On y discute de la théorie et de l'applicabilité de ces techniques. Cet article comprend un certain nombre de cas étudiés à titre d'exemple. Il renvoie aussi à l'évolution des étalons internationaux de mesure de contraintes résiduelles et aux développements à venir.

    2018-01-01

    Research suggests that interracial mentoring relationships are strained by negative affect and low rapport. As such, it stands to reason that strategies that decrease negative affect and increase rapport should improve these relationships. However, previous research has not tested this possibility. In video-chats (Studies 1 and 2) and face-to-face meetings (Study 3), we manipulated the degree of mutual self-disclosure between mentees and mentors, a strategy that has been shown to reduce negative affect and increase rapport. We then measured negative affect and rapport as mediators, and mentee performance (quality of speech delivered; Studies 1 and 3) and mentor performance (warmth and helpfulness; Studies 2 and 3) as key outcomes. Results revealed that increased self-disclosure decreased negative affect and increased rapport for both mentees and mentors. Among mentees, decreased negative affect predicted better performance (Studies 1 and 3). Among mentors, increased rapport predicted warmer feedback (Studies 2 and 3). These effects remained significant when we meta-analyzed data across studies (Study 4), and also revealed the relationship of rapport to more helpful feedback. Findings suggest that affect and rapport are key features in facilitating positive outcomes in interracial mentoring relationships.

    Full Text Available Positive relationships between instructors and students are critical to effective learning in the classroom. Rooted in the Scholarship of Teaching and Learning (SoTL, and centered at the crossroads of interpersonal communication and instructional communication (Affective Learning Model, this study examines how instructors in a Taiwan ESL school build relationships with Taiwanese students. Instructors were interviewed regarding the behaviors they use to build rapport with their students. Results show that instructors build rapport with their students using several specific techniques: uncommonly attentive behaviors, common grounding behaviors, courteous behaviors, connecting behavior, information sharing behavior, a balancing of connection and authority, adaptation of rapport to student level, and provision of a respite to norms. The findings provide specific examples of how instructors can build rapport in intercultural classrooms.

    Dans les composants de la microélectronique, du fait de l'existence de singularités géométriques, de très fortes contraintes sont générées. Des micro-composants modèles, formés de lignes régulières déposées sur un substrat mono-cristallin sont utilisés pour mettre au point une méthode générique de détermination des contraintes mécaniques locales dans la ligne et dans le substrat. Pour cela, des mesures par diffraction des rayons X et des simulations sont mises au point. Le dispositif expérimental est décrit. Les simulations sont réalisées à l'aide de deux types d'approche: le modèle de Hu, analytique, et la méthode des éléments finis. Ces deux approches sont comparées entre elles, et une courbe universelle est établie, donnant la contrainte moyenne dans une ligne en fonction d'un paramètre incluant sa forme et les propriétés élastiques du substrat et de la ligne. Enfin, le couplage entre les mesures par diffraction de rayons X à haute résolution (HRXRD) et les simulations par éléments finis ouvrent une voie pour la détermination de contraintes locales.

    Grahe, Jon E; Sherman, Ryne A

    2007-10-01

    Previous studies have indicated that situational context impacts the rapport experience (e.g., F. J. Bernieri, J. S. Gillis, J. M. Davis, & J. E. Grahe, 1996; N. M. Puccinelli, L. Tickle-Degnen, & R. Rosenthal, 2003). The authors designed the present study to further document the behavioral and experiential predictors of dyadic rapport and to evaluate dyadic rapport experiences when contributions were required from both interactants. Participants (N = 60) were paired into dyads and instructed to complete children's puzzles. However, the dyadic members were restricted in how they could accomplish this task: Only one interactant was allowed to work on the puzzle and had to do so blindfolded, while the second interactant gave instructions. Results suggested that less attribution of responsibility to the worker and the instructor's experience of enjoyment and frustration were indicative of higher rapport. Other characteristics of dyads reporting higher dyadic rapport included difficulty completing the task and more communicative behavior. The results provide important information for the understanding of the dyadic experience of rapport.

Chaque dislocation est caractérisée par la direction de sa ligne et son vecteur de Burgers b. L’interface est définie par son plan qui est le plan basal pour les deux cristaux et une désorientation nulle. La mise en mouvement de la dislocation sous l’effet de la force image dépend de l’intensité de l’énergie d’interaction élastique dislocation-joint interphase et de la distance à laquelle se trouve la dislocation. La mise en mouvement est effective si l’intensité de la force image (Fi= -DE/d, DE est l’énergie d’interaction élastique est supérieure à la contrainte de Peierls.

    The aim of our program is to determine past, present and future emission inventories of carbonaceous particles from 1860 to 2100 for fossil fuel and biofuel sources. Emission inventories for savannah and forest fires have been developed by using burnt area products given by satellite for Asia and Africa. The strong collaboration with the different groups attending this GICC program has allowed to develop the following results. 1- With the improvement of algorithms and new choices for emission factors, emission inventories for black carbon (BC), primary organic carbon (OCp) and total organic carbon (OCtot) have been constructed for the period 1950 to 1997 for fossil fuel and biofuel sources. With these new development, biofuel sources have been seen to be significant, especially in the developing countries. 2- Past inventories have been developed for fossil fuel and biofuel sources from 1860 to 1997 by taking into account the evolution of fuel consumption, fuel use and emission factors. 3- Savannah and forest fire inventories have been constructed based on burnt area products, for Africa (1981-1991, 2000) and Asia (2000-2001). These results show the importance of using real time data instead of statistics. 4-Future emission inventory of black carbon by fossil fuel sources has been constructed for 2100 following the IPCC scenario A2 (catastrophic case) and B1 (perfect world). 5-Characterization of biofuel emissions has been realized by organizing an experiment in a combustion chamber where indian and chinese biofuels (fuelwood, agricultural wastes, dung-cake etc..). were burnt, reproducing the burning methods used in these countries. 6-Finally, the differences between the existing inventories of carbonaceous aerosols has been explained.

    Carbon dioxide (CO{sub 2}) is the second natural greenhouse gas in the Earth's atmosphere, after vapor water. Its concentration levels have been increasing by 25% due to human activities over the past 200 years, thus increasing the radiative forcing at the surface and potentially including major climate change for the next centuries. It is of primary importance to better quantify the role of carbon contained into the oceans and the land biota in moderating the anthropic perturbation. To do so, {sup 13}C and {sup 18}O isotopes are unique tools which allow to estimate indirectly the terrestrial CO{sub 2} fluxes based on atmospheric measurements. The present reports describes the experimental set-up used at the CFR-LMCE laboratory to measure the {sup 13}C and {sup 18}O natural abundance in atmospheric carbon dioxide. This technique requires high levels of both precision and accuracy because the geochemical signal nevertheless consists of very small changes in isotopic composition (on the order of 0.01 permits). Also, given the large number of samples to analyses routinely, it must be run in an automatic mode. Our experiment design consists of 'extraction line' where CO{sub 2} is separated cryogenically from the air, which is coupled to a (Finnigan MAT 252) mass spectrometer. (authors)

    The abatement of CO{sub 2} emissions is a huge technical and economical challenge. Fossil fuels, which represent 88% of the world primary energy consumption, are the main source of the 25 billions of CO{sub 2} released each year in the atmosphere. The mastery of CO{sub 2} emissions cannot come from a single technology but must result from the simultaneous implementation of several means, like the development of carbon-free energies and the mastery of fossil fuel emissions. The opportunities of progress are numerous and compatible with the economic development. This document presents, first, the different greenhouse gases, the CO{sub 2} emissions per country and the main sources of CO{sub 2} emissions (power and heat generation, transports). Then it presents different ways of abatement of CO{sub 2} emissions: clean coal technologies, gas combined cycles, CO{sub 2} sequestration, reduction of fuel consumption in transports, development of carbon-free energies: wind power, solar photovoltaic for decentralized power generation, nuclear energy for a competitive power generation and for CO{sub 2} abatement, biofuels of 2. generation and fuel cells. The conclusion stresses on the investments needed for the renewal and increase of energy capacities, and on the necessary visibility and moderation of emission abatement mechanisms (carbon trading and CO{sub 2} prices).

    The main outcomes of the project allowed to revise the carbon stock estimate of the national french forests, to clarify the interactions between climate and sylviculture according to the ecological profile of main species, to describe the changes in species area distribution for forest trees and pathogens. Different approaches for estimating the national carbon stock in forest biomass were investigated such as biomass equations and architectural models. Some conclusions in terms of adaptation scenario can be drawn. The global production potential of the french forest will be changed. This change is rapid and will occur a time interval shorter than average tree life duration. Species substitution and changing practices must be considered from now. The soil water holding capacity and the nutrient availability interact strongly with the climate effects and are therefore target factors for adapting forest stands to future changes. The dramatic change in the potential area distribution of most pathogens over France lead to recommend strong regulations for avoiding dissemination of fungal diseases and to anticipate the pathogen risks through species distribution.

    To measure rapport between medical students and standardized patients using observer ratings; to relate these ratings to students' emotional awareness and to behavior within the medical interaction; and to assess the relative validity of using excerpts of different lengths for the measurement of rapport. Third-year medical students (N=141) were videotaped during a 15-min interaction with a standardized patient, and rapport as well as other communication variables were measured using trained coders. Rapport was measured with good interrater reliability by trained coders who viewed three 1-min excerpts. Emotional awareness was measured by a test of recognizing facial expressions of emotion, self-ratings of emotional self-awareness, and peer ratings of interpersonal sensitivity. Finally, participants who viewed the videotapes while imagining themselves to be the patient (analogue patients) provided impressions of the students, including satisfaction. Rapport based on all three minutes was positively correlated with accuracy in decoding facial expressions of emotion, self-reported attention to one's own emotions, peer ratings of sensitivity, communication behaviors of the medical student and standardized patient, and analogue patients' positive impressions and satisfaction. Rapport based on just the first minute of the interaction was significantly related to many of these variables. Rating short excerpts of behavior is a valid and efficient methodology for capturing the concept of rapport. Clinicians, researchers, and educators should focus on rapport building, even very early in the medical visit.

    Full Text Available Dans le cadre d’une morphologie lexématique, les notions de thème et d’« espace thématique » ont fait leurs preuves pour rendre compte de l’allomorphie radicale des lexèmes en ce qui concerne la flexion. Leurs premières applications à la dérivation ont été prometteuses, mais un examen plus systématique soulève de nombreuses difficultés. L’articulation entre flexion et dérivation, forte pour les verbes, est faible pour les adjectifs et nulle pour les noms. Dans ces deux catégories, des travaux récents ont fait apparaître un important polymorphisme (plusieurs formes pour un même thème. La distinction entre un thème présuffixal « populaire » et un thème présuffixal « savant » reste pertinente, mais la sélection de l’un ou de l’autre n’est nullement automatique : elle entre dans un jeu de contraintes, comme, à l’intérieur de chaque thème, le choix des formes qui peuvent s’y trouver en concurrence. Ces contraintes sont principalement d’ordre lexical et visent à la cohérence de la famille dérivationnelle à laquelle appartiennent le lexème et son dérivé ; à la cohérence de la série dérivationnelle dans laquelle le dérivé doit s’intégrer ; à la cohérence entre le thème sélectionné et le registre – populaire ou savant – auquel appartient le mode de formation. Elles visent également un maximum de sauvegarde, dans le dérivé, des dimensions phonique et graphique de la forme libre. Elles visent enfin une « bonne formation » phonologique du dérivé : syllabation, dissimilation, optimum prosodique.

  6. (ReExamining the Feminist Interview: Rapport, Gender “Matching,” and Emotional Labour

    Directory of Open Access Journals (Sweden)

    2017-11-01

    Full Text Available Rapport is usually considered key to any interview situation: building the right kind of rapport can be the difference between success and failure in obtaining the required data. In feminist research, rapport is intended to be of a particular kind: created through mutual sharing, minimal power hierarchies, and a feeling of genuine trust between interviewer and interviewee (Oakley, 1981. There is a tension here of which feminist researchers and scholars should remain critical, as the idea of good feminist rapport can clash with the necessity of “getting the data.” Building rapport can entail minimising strongly held viewpoints, working hard on one’s emotions to ensure they do not reveal true thoughts, or suggesting an attitude of trust and mutual understanding that may feel disingenuous. If rapport is often a performance by the researcher, then this can clash with the intended open and honest feminist approach. In some cases, then, building rapport may pose a challenge to genuinely following a feminist approach to the research interview. In this paper, I wish to explore this tension in more detail in the context of the one-off interview and to what extent it can be resolved.

    In the nuclear energy industry, the use of components made of austenitic stainless steel is widely spread, because of its specific thermal properties. The assembly of these pressure vessels and piping by welding processes often requires surface mechanical operations. These operations aim at hardening surfaces and lowering roughness. Nevertheless the main effect of these operations is the occurrence of residual stresses which can have positive or negative effects on the fatigue life. In this study, we focus on the evaluation and relaxation of residual stresses level on AISI 304L austenitic stainless steel tubular welded structures. Some of these rings are base metal rings (which stand as reference), the rest presents a longitudinal and symmetrical Y-weld joint, with or without grinding. Surface residual stresses, and their relaxation, were determined by using the X-ray diffraction method. (authors) [French] L'utilisation de composants en acier inoxydable austenitique, aux proprietes thermiques bien specifiques, est tres courante dans le domaine de la production d'energie nucleaire.

Cette etude porte sur la caracterisation et la relaxation des contraintes residuelles, determinees sur des eprouvettes annulaires specifiques en acier inoxydable austenitique de type 304L, a l'etat brut ou avec des soudures, arasees ou non. La methode de determination utilisee est la diffraction des rayons X. La relaxation de ces contraintes au cours d'essais de fatigue est egalement etudiee. (auteurs)

  10. The Extravert Advantage: How and When Extraverts Build Rapport With Other People.

    Duffy, Korrina A; Chartrand, Tanya L

    2015-11-01

    Extraverts are better than introverts at building rapport, but it remains unknown what they do behaviorally to better connect with other individuals. We hypothesized that extraverts mimic more than introverts as a way to build rapport; however, we predicted that this social skillfulness of extraverts emerges only when they are motivated to affiliate. In Study 1, we found that extraversion predicted increased mimicry when an affiliation goal was present, but not when an affiliation goal was absent. In Study 2, we found that mimicry mediates the relationship between extraversion and rapport, but only when an affiliation goal is present. Our findings are the first to identify a behavior that extraverts engage in that helps them build rapport. Furthermore, our studies show that this skillfulness of extraverts emerges only when they are motivated to affiliate, providing evidence in favor of the reward-sensitivity-as-core model of extraversion over the sociability-as-core model of extraversion. © The Author(s) 2015.

    Rapport is a primary component in the development of a therapeutic relationship between health-service professionals and clients. Presession pairing is a procedure often recommended in behavior analytic practice to build rapport with clients. However, many service providers may not exhibit presession pairing skills correctly or at a sufficient rate. The current study aimed to operationally define therapist behaviors that are indicative of presession pairing and to train direct care staff to implement said skills.

  14. Interviewing Practices, Conversational Practices, and Rapport: Responsiveness and Engagement in the Standardized Survey Interview.

    Science.gov (United States)

    Garbarski, Dana; Schaeffer, Nora Cate; Dykema, Jennifer

    2016-08-01

    "Rapport" has been used to refer to a range of positive psychological features of an interaction -- including a situated sense of connection or affiliation between interactional partners, comfort, willingness to disclose or share sensitive information, motivation to please, or empathy. Rapport could potentially benefit survey participation and response quality by increasing respondents' motivation to participate, disclose, or provide accurate information. Rapport could also harm data quality if motivation to ingratiate or affiliate caused respondents to suppress undesirable information. Some previous research suggests that motives elicited when rapport is high conflict with the goals of standardized interviewing. We examine rapport as an interactional phenomenon, attending to both the content and structure of talk. Using questions about end-of-life planning in the 2003-2005 wave of the Wisconsin Longitudinal Study, we observe that rapport consists of behaviors that can be characterized as dimensions of responsiveness by interviewers and engagement by respondents. We identify and describe types of responsiveness and engagement in selected question-answer sequences and then devise a coding scheme to examine their analytic potential with respect to the criterion of future study participation. Our analysis suggests that responsive and engaged behaviors vary with respect to the goals of standardization-some conflict with these goals, while others complement them.

    In the exploratory study reported here, we tested the efficacy of an intervention designed to train teenagers with Möbius syndrome (MS) to increase the use of alternative communication strategies (e.g., gestures) to compensate for their lack of facial expressivity. Specifically, we expected the intervention to increase the level of rapport experienced in social interactions by our participants. In addition, we aimed to identify the mechanisms responsible for any such increase in rapport. In the study, five teenagers with MS interacted with three naïve participants without MS before the intervention, and with three different naïve participants without MS after the intervention. Rapport was assessed by self-report and by behavioral coders who rated videos of the interactions. Individual non-verbal behavior was assessed via behavioral coders, whereas verbal behavior was automatically extracted from the sound files. Alignment was assessed using cross recurrence quantification analysis and mixed-effects models. The results showed that observer-coded rapport was greater after the intervention, whereas self-reported rapport did not change significantly. Observer-coded gesture and expressivity increased in participants with and without MS, whereas overall linguistic alignment decreased. Fidgeting and repetitiveness of verbal behavior also decreased in both groups. In sum, the intervention may impact non-verbal and verbal behavior in participants with and without MS, increasing rapport as well as overall gesturing, while decreasing alignment.

    Physician rapport with patients is described as a vital component of relationship-centered care, but rapport-building communication behaviors may exceed boundaries and instead indicate patronizing behavior toward patients with disabilities. This paper addresses the types of communication behaviors and contexts for interpreting when rapport building extends beyond boundaries toward patients with disabilities. Videotaped interactions between third- and fourth-year medical students (N = 142) and standardized patient educators with physical disabilities were qualitatively analyzed. Results suggest six primary themes of exceeding expected rapport boundaries, including baby talk (ie, exaggerated nonverbal gestures and "we" language to indicate "you"), kinesic movement (ie, stiff posture and awkward handshakes), vocalics (ie, volume or pitch that interfered with the flow of conversation), relationship assumptions (ie, communicating assumptions that relationships were grounded in care-receiving), emotional divergence from patient disclosure (ie, minimizing or embellishing disability), and inconsistency with patient emotional cues (ie, responding to negative or neutral disclosure by overly accentuating positive interpretation). This study suggests that communication behaviors generally described as positive, rapport-building behaviors can pose negative implications when they exceed the expected quantity or duration, when they are inconsistent with patient verbal disclosure, or when verbal and nonverbal messages are inconsistent. Identified themes serve as examples to understand when rapport building exceeds beyond affiliation and instead appears to indicate patronizing behavior toward patients with disabilities. Suggestions for interpreting communication behaviors within the context of patient disclosure and building capacity to distinguish attitudes and biases limiting communication are addressed.

  18. Considering Face, Rights, and Goals: A Critical Review of Rapport Management in Facilitator-Guided Simulation Debriefing Approaches.

    The rapport between facilitators and learners contributes to a conducive learning environment during simulation debriefing, but a theory to guide rapport management (RM) is lacking. The RM model is a potentially relevant conceptual framework because it describes three interrelated components of rapport-face, rights, and goals-which, when threatened, affect the rapport between interactants. This critical review explores how studies in the simulation debriefing literature describing postevent facilitator-guided debriefing approaches can be viewed through the lens of the RM model. All 34 identified studies alluded to at least one component of rapport, with less than half alluding to all three. There is preliminary evidence that the management of all three components of rapport during debriefing may contribute to improving short-term learning outcomes. Future studies could explore how the RM model can be used to guide debriefing approaches in various contexts and clarify why or how these approaches work.

  19. Testing the relationship between mimicry, trust and rapport in virtual reality conversations.

    People mimic each other's actions and postures during everyday interactions. It is widely believed this mimicry acts as a social glue, leading to increased rapport. We present two studies using virtual reality to rigorously test this hypothesis. In Study 1, 50 participants interacted with two avatars who either mimicked their head and torso movements at a 1 or 3 second time delay or did not mimic, and rated feelings of rapport and trust toward the avatars. Rapport was higher towards mimicking avatars, with no effect of timing. In Study 2, we aimed to replicate this effect in a pre-registered design and test whether it is modulated by cultural ingroup-outgroup boundaries. Forty participants from European or East Asian backgrounds interacted with four avatars, two of European appearance and two of East Asian appearance. Two avatars mimicked while the other two did not. We found no effects of mimicry on rapport or trust ratings or implicit trust behaviour in a novel maze task, and no effects of group status or interactions. These null results were calculated in line with our pre-registration. We conclude that being mimicked does not always increase rapport or trust, and make suggestions for future directions.

  20. Developing Rapport with Children in Forensic Interviews: Systematic Review of Experimental Research.

    2015-08-01

    The vast majority of guidelines recommend that developing rapport with children is essential for successful forensic child interviewing; however, the question remains as to whether there is a sufficient body of scientific research to generate evidence-based guidelines for developing rapport with children in legal contexts. To answer this question, we conducted a systematic review of the literature to identify experimental studies of the effects of rapport-building methods on the reliability of children's reports. Independent raters applied 12 exclusion criteria to the 2,761 potentially relevant articles located by electronic and hand searches of the literature. Experimental studies were few. Although studies to date are a beginning, the overall scientific base is weak regarding even basic issues such as how to best define rapport and the efficacy of common rapport-building techniques. This systematic review highlights what we know, what we do not know, and how much more we need to know to create evidence-based best practice. Recommendations for reshaping the research agenda are discussed. Copyright © 2015 John Wiley & Sons, Ltd.

  1. Developing Rapport and Therapeutic Alliance During Telemental Health Sessions with Children and Adolescents.

    2016-04-01

    The purpose of this study was to describe the special considerations for building rapport and establishing a therapeutic alliance when conducting mental health evaluations for children and adolescents via videoconferencing. The authors review the literature and describe their experience in conducting mental health evaluations, developing rapport, and establishing a therapeutic alliance during telemental health practice. Clinical need and shortages of clinicians with expertise in evaluating mental conditions for children and adolescents in underserved communities have stimulated the rapid expansion of telemental health programs while the research base continues to develop. The emerging evidence base and clinical experience suggest that teleclinicians can, and do, build rapport and establish a therapeutic alliance during telemental health sessions with youth and families. Families may be more accepting of telemental health approaches than clinicians. The impact that technology, equipment, site staff, community supports, cultural identification, and teleclinicians' characteristics have on building rapport and establishing a therapeutic alliance should be considered when establishing a telemental health service. Staff at the patient site and referring providers have a valuable role in supporting the therapeutic alliance between telemental health providers and their patients, and ultimately supporting the success of a telemental health program. Teleclinicians are creative in transcending the videoconferencing technology to evaluate patients using guideline-based care. Further research is needed to determine how clinicians build rapport and establish a therapeutic alliance during telemental health sessions, and whether the therapeutic alliance is associated with the accuracy of evaluation and outcomes.

  3. Do Prosecutors Use Interview Instructions or Build Rapport with Child Witnesses?

    Science.gov (United States)

    Ahern, Elizabeth C; Stolzenberg, Stacia N; Lyon, Thomas D

    2015-08-01

    This study examined the quality of interview instructions and rapport-building provided by prosecutors to 168 children aged 5-12 years testifying in child sexual abuse cases, preceding explicit questions about abuse allegations. Prosecutors failed to effectively administer key interview instructions, build rapport, or rely on open-ended narrative producing prompts during this early stage of questioning. Moreover, prosecutors often directed children's attention to the defendant early in the testimony. The productivity of different types of wh- questions varied, with what/how questions focusing on actions being particularly productive. The lack of instructions, poor quality rapport-building, and closed-ended questioning suggest that children may not be adequately prepared during trial to provide lengthy and reliable reports to their full ability.

    2017-01-01

    Young people suspected of being sexually exploited are unlikely to have made prior disclosures before being approached by authorities, and this can make them especially uncomfortable when involved in investigations. Semistructured interviews were conducted with frontline social workers and law enforcement practitioners about their experiences interacting with youth during child sexual exploitation investigations. The findings provided some tentative insights into the processes by which practitioners sought to establish rapport with young people who have been exploited and establish themselves as trustworthy abuse disclosure recipients. Practitioners reported that rapport building in child sexual exploitation cases not only occurred over lengthy periods of time (e.g., months or years) but also required repeated contacts between the practitioners and young people, during which practitioners minimized their roles as authorities and maximized their authenticity as caring people. Practitioners mentioned the importance of dependability, lightheartedness, and having a casual demeanor. Findings have implications for managing reluctance and understanding rapport building when working with possible victims.

    This study tested the effects of narrative practice rapport building (asking open-ended questions about a neutral event) and a putative confession (telling the child an adult "told me everything that happened and he wants you to tell the truth") on 4- to 9-year-old maltreated and nonmaltreated children's reports of an interaction with a stranger who asked them to keep toy breakage a secret (n = 264). Only one third of children who received no interview manipulations disclosed breakage; in response to a putative confession, one half disclosed. Narrative practice rapport building did not affect the likelihood of disclosure. Maltreated children and nonmaltreated children responded similarly to the manipulations. Neither narrative practice rapport building nor a putative confession increased false reports. © 2014 The Authors. Child Development © 2014 Society for Research in Child Development, Inc.

    2017-01-01

    This article explores two clinical phenomena-pornography and conspiracy thinking-that are highly relevant today and can be observed specifically among adolescent boys in the early stages of post-puberty: conspiracy thinking and the viewing of pornographic videos. It shows that the Lacanian concepts of the Real (of puberty) and the sexual non-rapport help us understand the psychopathological aspects of these two phenomena. Watching pornographic material becomes equivalent to a conspiracy theory about the sexual non-rapport; both in fact deny the effect of what puberty introduces as radically new.

    2009-01-01

    Therapeutic rapport between counselors and clients in drug user treatment has been shown to be an important predictor of follow-up outcomes. This naturalistic study investigated the relationship of counseling rapport to drug-related topics discussed in counseling sessions in a sample of 330 clients and nine counselors. These voluntary clients had been admitted to a private, for-profit outpatient methadone treatment in Texas between September 1995 and August 1997 and received no-fee services for a year for participation in this study. The data were gathered using forms in the TCU community treatment assessments (www.ibr.tcu.edu) that measured intake information, counseling session topics, and counselor evaluation of the client. A majority were males, Hispanic, had a pending legal status and the average age was 39. Co-occurring drug dependence for these heroin users included cocaine (38%) and alcohol (31%). The results supported the hypothesis that higher rapport would be associated with addressing clients in a more "supportive approach" that emphasized relapse prevention and strengths-building while lower rapport would be associated with a punitive counseling style that stressed program rules and compliance. The influences of client background, counselor differences, and during-treatment positive urines were also examined. Although counselors differed in their general manner of dealing with clients, each also showed flexibility determined in part by client behavior (such as continued cocaine use). The findings indicate that focusing on constructive solutions is the preferred counseling approach.

  18. The role of empathy in establishing rapport in the consultation: a new model.

    Science.gov (United States)

    Norfolk, Tim; Birdi, Kamal; Walsh, Deirdre

    2007-07-01

    Considerable research has been conducted recently into the notion of patient-centred consulting. The primary goal of this approach is to establish a clear understanding of the patient's perspective on his or her problem, and to allow this understanding to inform both the explanation and planning stages of the consultation. The quality of this understanding is largely determined by the empathic accuracy achieved by the doctor; the primary benefit is a therapeutic rapport between doctor and patient. To highlight the role of empathy and communication skills in establishing rapport, we initially developed a model which seeks to draw the various motivational and skill elements identified in separate research papers into a comprehensive model of the journey towards shared understanding between doctor and patient. We then conducted an initial validation of the model via qualitative analysis involving general practitioners (GPs) and clinical psychologists. The validation offered encouraging support for the principal elements of the model. Specific suggestions for clarification and extension were then incorporated in a revised model. The model appears to capture the dynamic process of establishing a therapeutic relationship (rapport) between doctor and patient, defined by the quality of the doctor's understanding of the patient's perspective on his or her problem. Arguably, the most important contribution of the model is to highlight the fact that 'empathy' and consequent 'rapport' are not mystical or exclusive concepts but, rather, involve the use of specific skills accessible at some level by all.

    2017-08-01

    A variety of treatment outcomes in chronic pain are influenced by patient-clinician rapport. Patients often report finding it difficult to explain their pain, and this potential obstacle to mutual understanding may impede patient-clinician rapport. Previous research has argued that the communication of both patients and clinicians is facilitated by the use of pain-related images in pain assessments. This study investigated whether introducing pain-related images into pain assessments would strengthen various components of patient-clinician rapport, including relative levels of affiliation and dominance, and interpersonal coordination between patient and clinician behaviour. Videos of 35 pain assessments in which pain images were present or absent were used to code behavioural displays of patient and clinician rapport at fixed intervals across the course of the assessment. Mixed modelling was used to examine patterns of patient and clinician affiliation and dominance with consultation type (Image vs Control) as a moderator. When pain images were present, clinicians showed more affiliation behaviour over the course of the consultation and there was greater correspondence between the affiliation behaviour of patient and clinician. However, relative levels of patient and clinician dominance were unaffected by the presence of pain images in consultations. Additional analyses revealed that clinicians responded directly to patients' use of pain images with displays of affiliation. Based on the results of this study, we recommend further investigation into the utility and feasibility of incorporating pain images into pain assessments to enhance patient-clinician communication.

  20. Establishing rapport: Physicians' practice and attendees' satisfaction at a Primary Health Care Center, Dammam, Saudi Arabia, 2013.

    Science.gov (United States)

    Al Ali, Ayat A; Elzubair, Ahmed G

    2016-01-01

    Establishing rapport is an important step in physician-patient communication resulting in a positive effect on patient satisfaction and overall clinical outcomes. However, there is a dearth of studies on the condition of doctor-patient relations in Saudi Arabia. This study was performed to estimate the proportion of physicians who have a good rapport with patients in their practice and the proportion of satisfied attendees. A cross-sectional study was conducted at a Primary Health Care Center, Dammam, KSA. The data were collected through a structured self-administered questionnaire given to samples of attendees and physicians to estimate patient satisfaction and the practice of rapport by physicians. A total of 374 attendees and 27 physicians participated in the study. The percentage of physicians who had good rapport was 51.9%. Factors that showed significant relationship with rapport practice were: Physician's age (p = 0.016), physician's experience (p = 0.043), and professional status (p = 0.031). The attendees satisfied with their physician's rapport with them were 50.5%. Factors that showed significant relationship with satisfaction were: Attendee's age (p rapport with patients and patients' satisfaction with physicians' empathy is not high. Training is required to optimize physician-patient communication.

    2006-11-01

    Full Text Available Dans cet article, on se propose de présenter les premiers résultats de l'étude de la méthode d'évaluation des contraintes par mesure de déformations différées d'une carotte après son extraction. Le travail correspondant a été réalisé dans le cadre du projet ARTEP Fracturation hydraulique . Les principes de cette méthode et les quelques éléments d'interprétation récemment publiés dans la littérature sont exposés dans un premier temps. Les résultats de deux campagnes de mesures sur deux puits de la SNEA-P (Soudron, novembre 1985 et Lanot, juillet 1986 sont ensuite présentés. Ces essais ont mis en évidence que les déformations différées d'une carotte dues au relachement des contraintes sont effectivement mesurables. Cependant, une interprétation quantitative de ces mesures nécessite une amélioration des conditions expérimentales (stabilisation thermique, stabilisation de l'état de saturation. This article describes the first results of research on a method of evaluating stresses by measuring the differred deformations of a core sample after it has been extracted. The corresponding research was done within the framework of an ARTEP project on Hydraulic Fracturing . The principles of this method and several interpretation aspects published recently in the literature are described in the first part. Then the results of two measurement campaigns using two SNEA-P wells (Soudron in November 1985 and Lanot in July 1986 are described. These tests revealed that the differed deformations of a core sample due to the relaxing of stresses can effectively be measured. However, a quantitative interpretation of these measurements requires an improvement to be made in the experimental conditions (thermal stabilization, stabilization of the state of saturation.

  5. Developpement d'une plateforme de calcul d'equilibres chimiques complexes et adaptation aux problemes electrochimiques et d'equilibres contraints

    Science.gov (United States)

    Neron, Alex

    Avec l'arrivée de l'environnement comme enjeu mondial, le secteur de l'efficacité énergétique prend une place de plus en plus importante pour les entreprises autant au niveau économique que pour l'image de la compagnie. Par le fait même, le domaine des technologies de l'énergie est un créneau de recherche dont les projets en cours se multiplient. D'ailleurs, un des problèmes qui peut survenir fréquemment dans certaines entreprises est d'aller mesurer la composition des matériaux dans des conditions difficiles d'accès. C'est le cas par exemple de l'électrolyse de l'aluminium qui se réalise à des températures très élevées. Pour pallier à ce problème, il faut créer et valider des modèles mathématiques qui vont calculer la composition et les propriétés à l'équilibre du système chimique. Ainsi, l'objectif global du projet de recherche est de développer un outil de calcul d'équilibres chimiques complexes (plusieurs réactions et plusieurs phases) et l'adapter aux problèmes électrochimiques et d'équilibres contraints. Plus spécifiquement, la plateforme de calcul doit tenir compte de la variation de température due à un gain ou une perte en énergie du système. Elle doit aussi considérer la limitation de l'équilibre due à un taux de réaction et enfin, résoudre les problèmes d'équilibres électrochimiques. Pour y parvenir, les propriétés thermodynamiques telles que l'énergie libre de Gibbs, la fugacité et l'activité sont tout d'abord étudiées pour mieux comprendre les interactions moléculaires qui régissent les équilibres chimiques. Ensuite, un bilan énergétique est inséré à la plateforme de calcul, ce qui permet de calculer la température à laquelle le système est le plus stable en fonction d'une température initiale et d'une quantité d'énergie échangée. Puis, une contrainte cinétique est ajoutée au système afin de calculer les équilibres pseudo-stationnaires en évolution dans le temps. De plus, la

  8. Rapport between Cancer Patients and Their Physicians is Critical for Patient Satisfaction with Treatment Decisions.

    Science.gov (United States)

    Umihara, Junko; Nishikitani, Mariko; Kubota, Kaoru

    2016-01-01

    Cancer patients' satisfaction with their treatment decisions has been demonstrated to be associated with improved health outcomes, but few studies of this issue have been conducted in Japan. To explore key factors in enhancing patient satisfaction, we assessed the association between their satisfaction and their relationships with their physicians. We conducted cross-sectional questionnaire surveys among patients who had received cancer treatment. One source was outpatients from a cancer center hospital, and the other was through the website of Japan's most popular newspaper. The questionnaire included demographic questions and general self-rated life status issues, such as peace of mind, quality of life, daily activities, family relationships, rapport with attending physician, assessment of the physician's explanations, and feelings of happiness during the previous week. Of 576 respondents, 383 subjects said they were satisfied and 193 dissatisfied. It was confirmed that the online survey was comparable to the paper-based survey in examining patient satisfaction. The dissatisfied group included more females and fewer subjects who were forced to retire from jobs than the satisfied group. The patients in the satisfied group had a more favorable subjective opinion of their recent life. The patients in the dissatisfied group received more chemotherapy and had more side effects than those in the satisfied group. Assessment of the physician's role showed significant differences between the two groups; the patients in the satisfied group felt more than those in the dissatisfied group that their physicians' explanations of treatment were sufficient and were satisfied with their rapport with their physicians. Multiple logistic regression analysis revealed that rapport with physicians was a significant factor (odds ratio=3.79, 95% CI=2.25-6.39). Rapport between physicians and patients is one of the most important factors in patient satisfaction with treatment decisions.

    In 2016, the Australian Government committed further funds in support of quality rural health education to improve the health and wellbeing of rural and remote communities. The stated funding requirement for longer rural placements in all disciplines is an exciting opportunity for greater investment in interprofessional education to foster collaborative practice, a global system imperative for health care. This commentary explores how findings from earlier research, which investigated how students in a co-located area learn to work with other health professions, can be translated into practice. While recognising the importance of an individual's interpersonal capabilities, this commentary focuses on how the core contextual conditions for interprofessional-rapport-building opportunities (shared space, adequate time and balance of disciplines) were considered in one rural centre. Educational leaders and academics globally should recognise that offering health professional students opportunity to live and work together in extended placements in rural settings has potential benefits for interprofessional education. Understanding the contextual conditions for building rapport between health professional learners, and reflecting on these, potentially will lay the foundation for collaborative practice when these learners become health professionals. Through the reflective questions we pose, policy-makers, health managers and clinical leaders from all health disciplines can build on this foundation by considering the interpersonal capability and contextual conditions for rapport-building in the health workforce to foster a collaborative practice environment for graduates to embrace when they enter the health workplace.

    Full Text Available Les travaux de recherche en didactique de l’ecriture sont traverses par deux courants: un courant qui emprunte a differentes sciences sociales la notion de representations; un second courant qui emprunte a la linguistique la notion de formes discursives. Mon propos est d’essayer de mettre en relation ces deux approches. Pour cela, il est organise en trois temps: (a tout d’abord j’evoque les evolutions recentes de la recherche en didactique de l’ecriture, evolutions qui incitent a faire appel a la notion de representations; puis (b j’analyse cette notion. J’explique pourquoi, en didactique de l’ecriture, on utilise la notion de representations sans y adjoindre l’adjectif “sociales”; puis j’explique pourquoi un certain nombre de chercheurs preferent la notion de rapport a l’ecriture a celle de representations de l’ecriture; enfin, (c j’aborde les relations entre le rapport a l’ecrit et l’apprentissage des formes discursives.

    The influence of thermal treatment on mechanical stress state of Al alloy samples and cylinder head have been study by X ray diffraction. The experimental difficulties produced by an important grain size of the alloys led us to the optimization of the parameters of the X ray diffraction setup. The systematic study of the factors influence would imply a prohibitive number of experiments, whereas the methodology of Taguchi experiment plans allows a definition of each factor role and of optional conditions of the X ray diffraction setup with a very low number of experiments. Then the minimization of the uncertainty on stress results has been reached. In the case of cylinder head, after quench, the stress state is heterogeneous (-100MPa des procédés de traitement thermique des alliages d'aluminium utilisés dans l'industrie automobile. Nous avons caractérisé par diffraction des rayons X, l'état mécanique d'éprouvettes et de culasses en aluminium à différents stades de traitement.

    Full Text Available L’arachide est cultivée par plus de 100 pays dans le monde. Les principaux producteurs sont la Chine et l’Inde qui fournissent plus de 60 % de la production mondiale. L’Afrique assure 25 % de la production avec le Nigéria, le Sénégal et le Soudan principalement. Au Sénégal, dans les années 1960, la culture de l’arachide s’était développée comme culture de rente (production d’huile et de tourteau destinée à l’exportation avec une ouverture croissante sur le marché mondial. Cette culture fut le moteur du développement de l’économie sénégalaise et a assuré jusqu’à 80 % des exportations et fourni la majeure partie des revenus monétaires en milieu rural. Mais à partir de 1970 et notamment depuis les années 1990, on a assisté à une véritable crise de la filière arachidière et les différentes politiques agricoles n’ont pas toujours permis la relance de la filière. Ce travail est une synthèse des informations recueillies sur l’arachide au Sénégal. Il revient sur l’importance de la culture, fait un état des lieux sur la production et la commercialisation, ressort les différentes contraintes de la production et propose des pistes pour la relance de la filière.

  8. Normal Stresses and Interface Displacement: Influence of Viscoelasticity on Enhanced Oil Recovery Efficiency Contraintes normales et déplacement d’interface : influence de la viscoélasticité sur l’efficacité de la récupération assistée

    2013-01-01

    Full Text Available One of chemical Enhanced Oil Recovery (EOR methods consists in injecting aqueous solutions of polymers into the reservoir in order to improve mobility ratio between the injected fluid and the remaining oil. This “polymer flooding” process is usually only characterized with the low shear viscosity of the injected fluid, even if these aqueous solutions are strongly shear thinning and may show high elastic properties evidenced by normal stresses appearance. In order to study the mechanisms at the interface level, we develop simple model experimentations with the goal of quantifying the influence of viscoelastic properties on fluid displacement in a simple geometry. For this purpose, we propose and characterize a model fluid formulation, for which elastic and viscous effects can be tuned systematically. We study then the displacement of a viscous oil by a Newtonian non elastic, a viscoelastic or a purely shear thinning fluid in a two dimensional flow cell. Observing the shape of the interface between aqueous fluids and displaced oil permits to appreciate viscoelasticity effects on the displacement. Using model geometries and controlled rheology fluids, we show that viscoelastic fluids tend to better displace immiscible liquids than Newtonian fluids and that those effects are closely related to the apparitions of normal stresses independently of shear thinning property or variation of interfacial tension as soon as viscous effects govern the flow. Une des méthodes de récupération assistée du pétrole (EOR - Enhanced Oil Recovery consiste à injecter dans les puits des solutions aqueuses de polymère pour améliorer le rapport de mobilité entre le fluide injecté et le pétrole qui reste dans le puits. Ce procédé de “polymer flooding” est communément caractérisé par la seule valeur de la viscosité à faible gradient de vitesse du fluide injecté, bien que les solutions employées présentent une forte rhéofluidification et

    2014-02-01

    A strong therapeutic alliance has been shown to improve mental health treatment outcomes in adults, but this topic has not been fully explored with youth. Adolescents, particularly justice-involved youth, stand to benefit greatly from an improved treatment experience. One quality which can improve treatment is mental health providers' interpersonal skills when attempting to build a therapeutic rapport with adolescent clients. Semi-structured interviews were conducted with 19 youth who screened positive for mental health concerns while in juvenile detention. Four themes were identified as important to improving the therapeutic alliance: Empathy, client-directed care, sequencing, and positive rapport. Suggestions for strengthening a therapeutic alliance are provided.

    Full Text Available L’administré transgresse un interdit juridique en n’obtempérant pas aux prescriptions d’un acte administratif, le plus souvent comminatoire (mais pas seulement. Mais l’administration se retrouve également, parfois, dans une situation de contrainte légale qui l’empêche de procéder ou de faire procéder à l’exécution de l’acte administratif ainsi suspendu à la volonté exclusive de l’administré. C’est par la loi ou face à une situation d’urgence que cette dernière pourra procéder à l’exécution de ses actes, étant entendu que ce cadre d’action, apparemment rigide, doit être relativisé. En effet, à côté de cette contrainte « exogène » due à la loi ou à l’urgence, on observe une contrainte « endogène » sécrétée par l’administration elle-même. Par là, la puissance publique manifeste une volonté remarquable de s’autolimiter dans l’exercice de ses compétences.The citizen breaks a legal prohibition by not obeying the prescriptions of an administrative, mostly threatening (but not only, act. But public administration sometimes also finds itself in a situation of legal constraint preventing it from proceeding to enforce an administrative act which therefore exclusively depends on the citizen’s will. It is only by using law or because it is faced with an emergency situation that public administration will be able to carry out the enforcement of its acts even if this apparently rigid action frame has to be relativised. Indeed, next to this “exogenous” constraint due to the law or to an emergency situation, we observe an “endogenous” constraint generated by the administration itself. In this, public authorities show a remarkable will of self-limitation in the exercise of its competencies.

    2015-12-01

    Full Text Available Marie Darrieussecq, a contemporary French writer, had been accused of plagiarism several times during her career. Besides defending her reputation, these accusations forced her to think about her conceptions on fiction and writing. Finally, in Rapport de police, she succeeded in showing a mirror to the society of contemporary French writers, in which a tendency towards denying the legitimacy of fiction in certain cases can be observed. This phenomenon is diagnosed by Tiphaine Samoyault as the extension of the domain of plagiarism on simple particles of life. Behind this tendency resurges the old controversy of Plato and Aristotle on mimesis and fiction. Along with Jean-Marie Schaeffer’s analysis on the function of fiction from a cognitive point of view unfolds an apology for lecture and for a fictional writing that is capable of saying the inexpressible and speak for those who don’t have access to language.

    Cloud computing infrastructure is now widely used in many domains, but one area where there has been more limited adoption is research computing, in particular for running scientific high-performance computing (HPC) software. The Robust Application Porting for HPC in the Cloud (RAPPORT) project took advantage of existing links between computing researchers and application scientists in the fields of bioinformatics, high-energy physics (HEP) and digital humanities, to investigate running a set of scientific HPC applications from these domains on cloud infrastructure. In this paper, we focus on the bioinformatics and HEP domains, describing the applications and target cloud platforms. We conclude that, while there are many factors that need consideration, there is no fundamental impediment to the use of cloud infrastructure for running many types of HPC applications and, in some cases, there is potential for researchers to benefit significantly from the flexibility offered by cloud platforms.

  3. Eating Animals to Build Rapport: Conducting Research as Vegans or Vegetarians

    Directory of Open Access Journals (Sweden)

    Katie MacDonald

    2014-12-01

    Full Text Available Notions of hospitality, community, and the fostering of rapport and connection are foundational concerns for conducting research across difference. Drawing on methodological literature, this paper considers how access to various communities and “good” data is structured by the notion that in order to develop rapport researchers accept the “food”, specifically “meat” offered by their hosts. When researchers are vegetarians or vegans, this can entail a conflict in which questions of hospitality, relationships, and responsibility to ethical commitments come to the fore. As such, we analyze methodological literature in which the logic of nonhuman animal sacrifice is considered a means to the ends of research through the development of “rapport”—often coded as an ethical relationship of respect to the participant. We draw on experiences of veg*n researchers to explore how this assumption functions to position the consumption of meat as a necessary undertaking when conducting research, and in turn, denies nonhuman animal subjecthood. We interrogate the assumption that culture and communities are static inasmuch as this literature suggests ways to enter and exit spaces leaving minimal impact, and that posits participants will not trust researchers nor understand their decisions against eating nonhuman animals. We argue that because food consumption is figured as a private and individual choice, animals are not considered subjects in research. Thus, we articulate a means to consider vegan and/or vegetarians politics, not as a marker of difference, but as an attempt to engage in ethical relationships with nonhuman animals. In so doing, we call for the inclusion of nonhuman animals in relationships of hospitality, and thereby attempt to politicize the practice of food consumption while conducting research.

    Intra-granular microstructure (a_0) and stress of tungsten rf magnetron sputtered thin films (diffracting phase (α-W and β-W). The stress state is imposed by the rf magnetron sputtering poxer (P). The films deposited with a high P are in a large compression stress state (in the α-W phase) and own a free stress lattice parameter higher than the tungsten bulk one. We have quantitatively shown that the transition of the stress state from the compressive (-1.7 GPa) to the tensile one (0.9 GPa) was clearly explained by the intra-granular modification (diminution of the stress free lattice prarameter from 0.3164 nm). From the XRD experiments, we have measured the coherently diffracting domains and the microdistorsions, which respectively decrease and increase with the generation of compressive stresses in the films. In addition, we have observed the dependence of the β-W phase with the tension in the films. Cet article concerne l'étude des propriétés mécaniques et microstructurales de films minces de tungstène (700 nm sur Si (100)) élaborés par pulvérisation magnétron en fonction de la puissance R.F. Les contraintes totales présentes dans les films (déterminées par la méthode de la flèche) sont très fortement influencées par la valeur de la puissance R.F. Elles varient de +1,2 GPa à -1,5 GPa pour des puissances de 350 W à 400 W. L'analyse par diffraction des rayons X a révélé la présence de phase β-W dans certains dépôts. Pour ces films, nous avons déterminé les contraintes dans chaque phase par la méthode des sin^2 psi. Les mesures d'intensité intégrée des pics de diffraction nous ont permis d'évaluer la proportion des phases dans chaque film. Nous avons vérifié le bon accord, en appliquant la règle des mélanges, entre les valeurs des contraintes totales et celles calculées à partir des résultats de diffraction X. Nous avons montré que la présence de la phase β-W semble favorisée par un état de tension des films (jusqu

    Superficial characteristics of a substrate, particularly the hardness, the elastic modulus and the wear resistance can be considerably improved by laser cladding. This high energy process causes thermal stresses, leading to residual stresses and substrate distortions. In this study, laser cladding is carried out onto an aluminium alloy with a Nd:YAG laser and a coaxial injection of Al 50Si powders. Residual stresses are determined by X-ray diffraction and by sample strain measurement. The differences of results between these two ways highlight the influence of the heat-affected zone (HAZ) under the coating. These differences can be explained by a model of three blocks: the coating, the HAZ and the substrate. The experimentation shows an optimal treatment speed, leading to maximum compression stresses interesting for the hardness and the wear resistance. Moreover, at a certain fixed speed, the thermal stresses balance each other in the sample and lead to the no-distortion of the substrate. Par la formation d'un dépôt, le rechargement laser permet d'amé liorer les caractéristiques superficielles d'un substrat, en particulier la dureté, le module d'élasticité et la résistance à l'usure. Ce procédé utilisant un faisceau de haute énergie crée dans le matériau traité des contraintes résiduelles d'origine thermique et des déformations du substrat. Dans cet article, le rechargement laser a été réalisé sur un alliage d'aluminium grâce à un laser Nd YAG et une injection coaxiale de poudres Al 50Si. Les contraintes résiduelles ont été étudiées par diffraction des rayons X et par la méthode de la flèche. Les différences de résultats entre ces deux méthodes ont permis de mettre en évidence l'influence de la zone affectée thermique (ZAT) en dessous du dépôt et ont pu être expliquées à l'aide d'un modèle de blocs correspondant respectivement au dépôt, à la ZAT et au substrat. L'expérimentation a révélé, entre autres, une vitesse de

    Participatory medicine and the availability of commercial technologies have given patients more options to view and track their health information and to communicate with their providers. This shift in the clinical process may be of particular importance in mental healthcare where rapport plays a significant role in the therapeutic process. In this review, we examined literature related to the impact of technology on the clinical workflow and patient-provider rapport in the mental health field between January 2014 and June 2017. Thirty three relevant articles, of 226 identified articles, were summarized. The use of technology clinically has evolved from making care more accessible and efficient to leveraging technology to improve care, communication, and patient-provider rapport. Evidence exists demonstrating that information and communication technologies may improve care by better connecting patients and providers and by improving patient-provider rapport, although further research is needed.

    Discrete trial instruction (DTI) is effective for teaching skills to children with autism spectrum disorder (ASD). Although effective, instructional settings can become aversive resulting in avoidant and escape-related behaviors. Given the significant social impairments associated with ASD, interventions that promote social approach and reduce avoidance are warranted. Rapport building or "pairing" the therapist and teaching setting with highly preferred activities prior to instruction can reduce problematic behaviors during subsequent instruction. However, the path from child-led play to DTI is not well established. Instructional fading may assist in bridging this gap. Four participants with ASD who were beginning an intensive behavioral intervention program were included in the current study. Participants progressed through nine stages of pairing and instructional fading with minimal problem behavior and high percentages of in-seat and close proximity to the therapist. Guidelines for incorporating rapport building strategies prior to intensive teaching with children with ASD are proposed.

    Full Text Available Le travail à domicile est une organisation ancienne. Il se décline dans une série d’activités salariées ou indépendantes, réalisées pour partie ou en totalité dans l’espace domestique. Le télétravail à domicile, basé sur l’utilisation de l’informatique et des technologies de l’information et de la communication, en représente un aspect moderne. Il redéfinit les frontières spatio-temporelles qui ont fortement structuré le monde du travail. Obligeant souvent à une forte implication, valorisé pour la liberté et la créativité, questionnant la séparation des sphères professionnelle et privée, le télétravail à domicile, lorsqu’il est pratiqué par des populations qualifiées et amatrices d’autonomie, peut être considéré comme emblématique des transformations contemporaines du rapport au travail et du rapport à l’emploi. Cette thématique mêle des enjeux transversaux et nous interroge sur l’évolution des modes de vie, sur de nouvelles figures de l’autorité et sur de nouvelles formes de recherche du bonheur au travail.Home work is an old type of organization. It corresponds to many activities which are salaried or independent and which are realized partially or entirely in domestic space. Home telework, using ICT, represents a modern form of home work. It changes space-time frontiers which have traditionally characterized work organization. It can require a strong implication, it can bring freedom and creativity, it questions the frontiers between work and non work: home telework, concerning qualified people who want autonomy, can be regarded as a symbol of contemporary transformations of work and employment.

    With increasing interest and research into interprofessional learning, there is scope to more deeply understand what happens when students from different professions live and study in the same location. This study aimed to explore the issue of co-location and its effects on how students learn to work with other professions. The setting for this study was a rural health education facility in Australia with close links to local health care and community services. Philosophical hermeneutics informed the research method. Interviews were undertaken with 29 participants, including students, academic educators and clinical supervisors in diagnostic radiography, medicine, nursing, nutrition and dietetics, pharmacy, physiotherapy, occupational therapy, and speech pathology. Photo-elicitation was used to facilitate participant engagement with the topic. The findings foreground the value of interprofessional rapport building opportunities for students learning to work together. Enabled by the proximity of different professions in shared educational, clinical and social spaces, interprofessional rapport building was contingent on contextual conditions (balance of professions, shared spaces and adequate time) and individual's interpersonal capabilities (being interested, being inclusive, developing interpersonal bonds, giving and receiving respect, bringing a sense of own profession and being patient-centred). In the absence of these conditions and capabilities, negative professional stereotypes may be inadvertently re-enforced. From these findings suggestions are made for nurturing interprofessional rapport building opportunities to enable students of different professions to learn to work together.

    Although age-related deficits in emotion perception have been established using photographs of individuals, the extension of these findings to dynamic displays and dyads is just beginning. Similarly, most eye-tracking research in the person perception literature, including those that study age differences, have focused on individual attributes gleaned from static images; to our knowledge, no previous research has considered cue use in dyadic judgments with eye-tracking. The current study employed a Brunswikian lens model analysis in conjunction with eye-tracking measurements to study age differences in the judgment of rapport, a social construct comprised of mutual attentiveness, positive feelings, and coordination between interacting partners. Judgment accuracy and cue utilization of younger (n = 47) and older (n = 46) adults were operationalized as correlations between a perceiver's judgments and criterion values within a set of 34 brief interaction videos in which 2 opposite sex college students discussed a controversial topic. No age differences emerged in the accuracy of judgments; however, pathways to accuracy differed by age: Younger adults' judgments relied on some behavioral cues more than older adults. In addition, eye-tracking analyses revealed that older adults spent more time looking at the bodies of the targets in the videos, whereas younger adults spent more time looking at the targets' heads. The contributions from both the lens model and eye-tracking findings provide distinct but complementary insights to our understanding of age-related continuities and shifts in social perceptual processing.

    The Alto project means the installation of an electron linear accelerator inside the experimental area of the tandem accelerator of the nuclear physics institute of Orsay (IPNO, France). This linear accelerator comes from CERN where it was operating as a pre-injector for LEP. This equipment will allow IPNO'teams to perform fast kinetics studies in a domain different from that of ELYSE accelerator. The time resolution will not be as high as that of ELYSE (picosecond) but will be sufficient (microsecond) to produce free radicals in aqueous and gaseous media. The main expectations of this installation can be classified according 3 axis: 1) basic research (mainly the study of nuclear matter through photo-fission, 2) research and development of accelerators (by providing a test bench for new high frequency systems and superconducting components), and 3) applied research for industry concerning: biochemistry under irradiation, radiation sensibility, DNA breaking, food and drug sterilization and behaviour of electronic components under irradiation. This rapport details the research program that could be achieved with this equipment, describes its contributions in terms of economic development, cooperation with industry, student training, and specifies the needed investment and the operating and maintenance costs.

    Full Text Available Les sociétés contemporaines connaissent un accroissement des inégalités, en termes de richesse et d’accès au pouvoir. Le fait gestionnaire, par son emprise croissante, joue un rôle particulièrement important dans l’actualisation des rapports de domination. Il se situe, en effet, à l'articulation entre les décisions politiques majeures et les transformations des sphères d'activité sociale. Mais c'est aussi par le renouvellement permanent de ses différentes composantes que le fait gestionnaire agit : procédant par expérimentations successives, il assure ainsi la perpétuation de rapports de domination, au cœur même des sphères économiques et professionnelles. Pour montrer la pertinence de cette approche, l’article élabore, dans le prolongement des acquis de la sociologie du travail, un modèle pour analyser la volonté gestionnaire de changer. En appliquant ce modèle à un vaste éventail de contextes professionnels, nous pointons et expliquons les effets de polarisation sociale qu’engendre cette volonté.The constant change at the heart relations oh dominationContemporary societies are experiencing growing inequalities in wealth and access to power. The process of “managerialism”, by its increasing influence, plays a particularly important role in updating the relations of domination. It is, indeed, located at the joint between the major policy decisions and changes in social spheres. But this process acts also by the constant renewal of its various components: proceeding by successive experiments, it ensures the perpetuation of relations of domination, at the heart of economic and professional spheres. To show the relevance of this approach, the paper develops, following the achievements of the sociology of work, a model to analyze the managerial will of change. Applying this model to a wide range of advanced professional contexts, we point out and explain the effects of social polarization generated by this will

    As professional case managers seek to improve outcomes, including the health status of their clients, it becomes imperative to gather and assess as much relevant information as possible to identify and address the client's needs in a holistic manner. Motivational interviewing is a highly effective technique case managers employ for this purpose. They also rely on it to move their clients toward a course of successful, desirable, and sustainable change, such as healthier diet, exercise, self-care, and adherence to medications regime and follow-up care. Across the case management spectrum, including hospitals, accountable care organizations, patient-centered medical homes, physician practices, clinics, and other settings in which case managers work with clients and their support systems. Motivational interviewing is a highly effective technique for gathering accurate and comprehensive information that is supportive of and additive to the assessment phase of the case management process. Using motivational interviewing, case managers can more readily uncover health and lifestyle needs of their clients. This results in building trusting relationships and developing rapport with clients, which can motivate them to move toward successful and desirable change. The design and implementation of a comprehensive and effective case management plan of care is facilitated by motivational interviewing, whereby professional case managers establish collaborative, respectful, trusting and individualized relationships with clients. Using the specific principles and techniques of motivational interviewing, case managers take a holistic approach to care to address a client's willingness and ability to change; addressing self-confidence and other emotional triggers that affect change and support the client's ability to embrace and sustain positive change.

    New patients are a particularly vulnerable population because they are at high risk of missing a subsequent visit or dropping out of care completely. However, few data exist on what new patients value in the beginning of a relationship with a new provider. Persons with HIV infection may be an ideal population to study the drivers of a positive initial patient-provider relationship, as it is a chronic and serious condition that requires a reliable, ongoing relationship with a provider. Informed by patients' real experiences, this study aims to identify what patients see as the most critical elements for building trust and rapport from the outset. We conducted longitudinal, in-person interviews with 21 patients new to the HIV clinic at the Michael E. DeBakey Veterans Affairs Medical Center in Houston, Texas, from August 2013 to March 2015. Patients were interviewed across three time points: once before their first provider visit, a second time within two weeks after the first visit, and a third time at 6 to 12 months after the first provider visit. We conducted 61 h of patient interviews. The mean age was 53 years; 52% were non-Hispanic white, 23% were non-Hispanic black and 19% were Hispanic. Patients described significant anxiety and vulnerability not just from HIV itself, but also in starting a relationship as a new patient to a new provider. Our analysis of these experiences revealed five actions providers can take to reduce their patients' anxiety and build trust early in the first visit: 1) provide reassurance to patients, 2) tell patients it's okay to ask questions, 3) show patients their lab results and explain what they mean, 4) avoid language and behaviors that are judgmental of patients, and 5) ask patients what they want [i.e., treatment goals and preferences]. Our study incorporates direct input from patients and highlights the unique psychological challenges that patients face in seeking care from a new provider. The actionable opportunities cited by

    It is suggested that "schizophrenic color", as the impression of schizophrenic disturbance of rapport, is closely related to the disturbance of communication, especially metacommunication, by many researchers. So the author defined a symptom named "the cognitive schema of others' position", which means others' time-space position in a patient's delusional world, as the symptom being expected to be closely related to the disturbance of the patient's metacommunication at the interaction with others in his delusional world. Then the author examined statistically the relationship of "schizophrenic color" (or the operational diagnosis of schizophrenia according to DSM-III) to "the cognitive schema of others' position" and at the same time to several forms of auditory hallucination having been considered to be significantly related to schizophrenia. 58 hallucinatory-delusional states (29 schizophrenia, 29 non-schizophrenia) were actually examined and some results were pointed out as follows. Observation of the "improper cognitive schema of others' position", which means the fantastic and impossible, for a human being, time-space position of others in a patient's delusional world, was statistically related to the deterioration of "schizophrenic color" or the operational diagnosis of schizophrenia according to DSM-III. This result was considered to be related to the supposition that the "improper cognitive schema of others' position" is a symptom representing the schizophrenic collapse of the cognitive time-space construction as well as the schizophrenic disturbance of metacommunication. Otherwise, the observation of hallucinatory voices speaking and answering directly to the patient, which has been expected to be one of the most important symptoms of schizophrenia, was not statistically related to the deterioration of "schizophrenic color" or the operational diagnosis of schizophrenia according to DSM-III. And the observation of hallucinatory voices arguing about the

    As patients become increasingly involved in their medical care, physician-patient communication gains importance. A previous study showed that physician self-disclosure (SD) of personal information by primary care providers decreased patient rating of the provider communication skills. The objective of this study was to explore the incidence and impact of emergency department (ED) provider self-disclosure on patients' rating of provider communication skills. A survey was administered to 520 adult patients or parents of pediatric patients in a large tertiary care ED during the summer of 2014. The instrument asked patients whether the provider self-disclosed and subsequently asked patients to rate providers' communication skills. We compared patients' ratings of communication measurements between encounters where self-disclosure occurred to those where it did not. Patients reported provider SD in 18.9% of interactions. Provider SD was associated with more positive patient perception of provider communication skills (pself-disclosure (47.1%). Patients reported that they would like to hear about their providers' experiences with a similar chief complaint (64.4% of patients), their providers' education (49%), family (33%), personal life (21%) or an injury/ailment unlike their own (18%). Patients responded that providers self-disclose to make patients comfortable/at ease and to build rapport. Provider self-disclosure in the ED is common and is associated with higher ratings of provider communication, rapport, and patient satisfaction.

Depuis une décennie on essaie d'utiliser la pression en leak-off dans les puits verticaux pour évaluer les deux contraintes horizontales en place. Une variante de l'opération précédente consiste à aller jusqu'à rompre la roche et propager la rupture : c'est la micro fracturation . L'interprétation des pressions obtenues reste basée principalement sur la mécanique linéaire de la rupture : paramètres élastiques et ténacité de la roche sont constants. On montre comment quatre facteurs - rapport des contraintes recherchées, existence ou non de fissure(s préexistante(s en paroi, pénétration du fluide dans ces fissures, filtration du fluide - peuvent conduire à des niveaux et des évolutions de pression très variés. Ils sont cependant insuffisants pour expliquer quelques observations courantes : la partie non-linéaire de la courbe pression-temps, la valeur du maximum de pression, sa variation avec le débit injecté en fracture. On montre comment la prise en compte d'effets poroélastiques en bout de fracture et d'un endommagement mécanique en paroi de puits pourrait permettre de faire mieux. Deux grandeurs apparaissent comme essentielles à l'interprétation : la limite supérieure de linéarité en pression, la pression de fermeture de la fracture.

    In order to increase the storage capacities of the media of magnetic recording one seeks to decrease the size of the magnetic fields which carry information. The growth of thin layers of magnetic alloys in ordered phases makes it possible to plan structures with very strong perpendicular magnetic anisotropy, necessary to obtain stable fields in spite of their reduced size. We studied, thanks to an original device of in temperature X-rays diffraction, the ordering of FePd layers or FePt deposited by MBE in different states of initial order and constraint, then submitted to heat treatment. The ordering occured along the growth axis. The structure of the layers is very inhomogeneous: not ordered and ordered domains coexist, with or without defect in the stacking of the L10 phase, even domains of other phases. The small zones, which have been ordered during the growth, do not seem to take part in the development of the long range order during the treatment. The evolution of the ordered fraction is identical whatever the imposed state of epitaxial stress. Modifications of the experimental conditions make it possible from now to plan more systematic measurements with a temperature history more rigorous in order to confirm these observations. Afin d'augmenter les capacités de stockage des media d'enregistre ment magnétique, on cherche à diminuer la taille des domaines magnétiques qui portent l'information.

    Accurate data on young people's sexual behaviour and sexual health practice is essential to inform effective interventions and policy. However, little empirical evidence exists to support methodological design decisions in projects assessing young people's sexual health, especially in African contexts. This short report uses original empirical data collected in Ghana in 2012 to assess the effects of data collection mode and interviewer gender on young people's reporting of sexual health and access to supportive sexual health resources. The findings indicate that the effect of data collection mode may vary by gender, and there is no indication of an interviewer gender effect for males in this study. Preliminary results suggest that building strong rapport with research participants in this context may lead to reduced sexual health data quality. These findings merit further investigation and have direct implications for the design of projects measuring sexual health and related variables in Ghana.

En réalité, et malgré la reconnaissance constitutionnelle de leur fonction d’or­ganisation et de représentation des citoyens, la monarchie marocaine a déployé une stratégie de dépérissement et de marginalisation des formations issues du mouvement national, tout en perpétuant un pluripartisme qui serve à maintenir et conforter son leadership. Les multiples élections qui ont scandé l’histoire politique du Maroc, ont fourni un cadre d’expression et de renouvellement du champ partisan, soigneusement contrôlé par la Monarchie et dénué de toute dimension réellement compétitive quant aux enjeux d’appropriation du pouvoir. En dépit de la libéralisation du régime amorcée depuis une décennie, et qui a laissé entrevoir un certain renouveau partisan, le multipartisme marocain relève du « pluralisme autoritaire », avec les contraintes et les dilemmes imposés par les modes de régulation politique des régimes autoritaires : pour les formations, accepter de continuer à jouer le jeu de l’intégration ou de la cooptation au risque d’affaiblir leurs assises sociales et d’augmenter leur discrédit populaire ; pour la monarchie, s’assurer du concours des structures partisanes à travers une certaine légiti­mité électorale, pour garantir sinon son hégémonie du moins sa stabilité et sa survie.

    2011-05-01

    Full Text Available Je m’interroge dans cet article sur les implications du principe libertarien de la pleine propriété de soi sur la question du rapport moral à soi-même. À travers le principe de la pleine propriété de soi, les libertariens défendent la liberté entière de chacun de vivre comme il l���entend, pourvu que les droits des autres soient respectés. Apparemment, ce principe n’a pas grand-chose à nous dire sur ce que nous sommes moralement autorisés à nous faire à nous-mêmes ou non. Certains libertariens, comme Vallentyne, soutiennent toutefois que le principe de la pleine propriété de soi est incompatible avec l’existence de devoirs envers soi. La pleine propriété de soi impliquerait l’indifférence morale du rapport à soi. Je soutiens dans cet article que le principe de la pleine propriété de soi n’implique pas que ce que nous nous faisons à nous-mêmes soit moralement indifférent. Je veux aussi montrer que même si les libertariens, et en particulier Vallentyne, soutiennent la thèse de l’indifférence morale du rapport à soi, celle-ci n’est pas liée à la thèse de la pleine propriété de soi, mais bien plutôt à leur subjectivisme moral.ABSTRACTI ask in this article what the libertarian principle of full self-ownership has to say about volontary actions directed towards oneself. Through the principle of full self-ownership, libertarians defend the persons’ individual liberty to live as they choose to do, as long as they don’t infringe on the rights of others. Apparently, this principle doesn’t have much to say about what we are morally allowed to do to ourselves or not. Some libertarians, however, like Vallentyne, maintain that, if we have duties or obligations to ourselves, then we cannot be full self-owner. In this perspective, full self-ownership would imply that what we do to ourselves is morally indifferent. I want to show in this article that full self-ownership is compatible with the

    To investigate associations between ratings of "thin slices" from recorded clinic visits and perceived patient-centeredness; to compare ratings from video recordings (sound and images) versus audio recordings (sound only). We analyzed 133 video-recorded primary care visits and patient perceptions of patient-centeredness. Observers rated thirty-second thin slices on variables assessing patient affect, physician affect, and patient-physician rapport. Video and audio ratings were collected independently. In multivariable analyses, ratings of physician positive affect (but not patient positive affect) were significantly positively associated with perceived patient-centeredness using both video and audio thin slices. Patient-physician rapport was significantly positively associated with perceived patient-centeredness using audio, but not video thin slices. Ratings from video and audio thin slices were highly correlated and had similar underlying factor structures. Physician (but not patient) positive affect is significantly associated with perceptions of patient-centeredness and can be measured reliably using either video or audio thin slices. Additional studies are needed to determine whether ratings of patient-physician rapport are associated with perceived patient-centeredness. Observer ratings of physician positive affect have a meaningful positive association with patients' perceptions of patient-centeredness. Patients appear to be highly attuned to physician positive affect during patient-physician interactions. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Dans les vallées de l'intérieur de la Provence, de grandes accumulations de tufs et de travertins sont liées aux sources karstiques importantes. En rapport avec l'évolution géomorphologique, les travertins anciens forment des balcons et des terrasses. La période récente de grande construction travertineuse débute souvent au Préboréal et se généralise dans l'Atlantique. Au cours du Néolithique final, cette sédimentation décroît en fonction de la détérioration climatique et de la déforestation liée à la pression anthropique. Cependant quelques barrages (dômes stromatolitiques et marais, avec dépôts de tourbes, persistent jusqu'à l'âge historique. Dans le Centre-Var, les dépôts de tufs restent actifs dans quelques sites refuges, dans les hautes vallées forestières, proches des sources karstiques, et sur quelques grandes cascades. De plus, le long des rivières, des cascades à tufs sont issues des aménagements de moulins et de canaux d'irrigation.La sédimentation des tufs dépend de nombreux facteurs en interaction, dont :- la minéralisation carbonatée des eaux des sources karstiques,- le régime hydrologique saisonnier,- l'écosystème régional et local (forêts, ripisylves,- le biotope algo-bryophytique.De nos jours, la sédimentation stromatolitique est en situation critique du fait de l'impact de multiples facteurs en rapport avec l'accroissement de l'urbanisation et les changements environnementaux :- pollution, accroissement de la turbidité sur les petits affluents résultant de l'agriculture mécanisée,- diminution drastique des débits dans les saisons de printemps-été, où l'activité algo-bryophytique est la plus favorable, du fait de l'augmentation générale des prélèvements.La période de sécheresse récente (2006-2008 a accentué ces impacts sur les barrages de tufs.

  1. Reflecting on the PRET A Rapporter Framework Via a Field Study of Adolescents? Perceptions of Technology and Exercise

    Directory of Open Access Journals (Sweden)

    Helen M Edwards

    2013-01-01

    Full Text Available PRET A Rapporter (PRETAR was developed to explicitly structure user-centered evaluation studies to ensure all necessary elements are individually and independently considered. Its creators see its benefit as twofold: for study design and in retrospective evaluations. We evaluate PRETAR’s potential by applying it retrospectively to one of our eHealth field studies in which we investigated the design requirements for mobile technologies that would support and motivate adolescents to exercise opportunistically. We also use PRETAR to evaluate the key literature for this eHealth study. This shows that typically the research methodology is under-reported. Then we document the study in terms of its purpose, resources, ethical concerns, data collection and analysis techniques, and manner of reporting the study. Finally, our reflection on the use of PRETAR leads us to propose that four different modes of the framework should be applied during the course of a study, that is, when reviewing, planning, conducting, and discussing.

    It has been verified that the Dall Energy Furnace have unique features: - The furnace will accept biomass fuel with moisture content in range 20% to 60% and still keep the flue gas temperature within +-10 deg. Celsius (for pre-set temperature 900 to 975 deg. Celsius); - The ash quality from the furnace is very good with no excessive sintering and without carbon in the ash; - Flue gas dust content at the furnace exit is below 50 mg/Nm3, while the content of NO{sub x} and CO is below 175 mg/Nm3 and 20 mg/Nm3, respectively. The Dall Energy biomass furnace consists of two separate stages which are combined in a single aggregate: an updraft gasification process and a gas combustion process. As the furnace is refractory lined and as the furnace can operate at low excess air it is possible to burn biomass with water content above 60%. No mechanical parts are used at temperatures above 200 deg. Celsius. This provides a very rugged system. In the gasifier section a combustible gas is produced with a low velocity at the top of the gasifier bed. This gas is combusted to a flue gas with extremely low dust content. Also, the NO{sub x} and CO content is very low. The temperature of the flue gas at the exit is kept low by injecting water spray together with the secondary air. (Author)

    The research project 'KLIMAT' was 1.1.2009 to 31.8.2012. The main goal of this project was to develop a 'best practice' methodology for quantifying the carbon footprint of products with a focus on fruits, vegetables, dairy and meat products. The methodology was tested on six selected case products. One of these products was the carrot. The product was selected because it is a product with high sales volume, a large part of the production takes place in Norway, and it may be assumed to represent the root vegetables which are a very important group of vegetable products. Oestfold Research, in conjunction with BAMA and Gartnerhallen, collected the necessary data to conduct the study. Data came from a group of 13 producers with ties to Laagendalen that all products supplied to the Laagen Gulrot for processing and packing. The producers were voluntarily affiliated with an online reporting system for a variety of information, including information about resource use that were used in this study. Climate track of carrot packed in the cup was, according to the methodology that was developed 0.39 kg Co2-ekv/kg product delivered to the consumer, 0.44 kg Co2-ekv/kg consumed carrot. (Author)

    This report on the new energy technologies has been written by a working group on request of the French ministry of economy, finances and industry, of the ministry of ecology and sustainable development, of the ministry of research and new technologies and of the ministry of industry. The mission of the working group is to identify goals and priority ways for the French and European research about the new technologies of energy and to propose some recommendations about the evolution of research incentive and sustain systems in order to reach these goals. The working group has taken into consideration the overall stakes linked with energy and not only the climatic change. About this last point, only the carbon dioxide emissions have been considered because they represent 90% of the greenhouse gases emissions linked with the energy sector. A diagnosis is made first about the present day context inside which the new technologies will have to fit with. Using this diagnosis, the research topics and projects to be considered as priorities for the short-, medium- and long-term have been identified: energy efficiency in transports, in dwellings/tertiary buildings and in the industry, development for the first half of the 21. century of an energy mix combining nuclear, fossil-fuels and renewable energy sources.

Lors d’une séance de remise à niveau en orthographe, les étudiant·e·s ont produit un extrait tiré d’un texte écrit par Fénelon entre 1701 et 1712. Cet extrait a fait l’objet de trois enquêtes étalées de 1873 à 2005 destinées à établir un bilan comparatif des connaissances des élèves du Cours Moyen 2° année à la 3° de collège. L’objectif de formation de cette séance était une réflexion sur l’orthographe du français et son enseignement à partir de pratiques orthographiques étudiantes. Pour l’objectif de recherche, il s’agissait d’analyser les zones de fragilité orthographique du français. Selon les travaux coordonnés par Lucci et Millet (1994, celles-ci se manifestent par les variations orthographiques contenues dans les productions, sont inhérentes au système et ne relèvent ni des scripteurs ni des situations d’écriture. Si tel est le cas, elles doivent aussi apparaitre dans les productions sous dictée d’adultes diplômé·e·s se destinant à l’enseignement primaire. Afin de favoriser leur émergence dans les productions de participant·e·s destiné·e·s à véhiculer la norme orthographique, la dictée a été contrainte. Les résultats indiquent un faible pourcentage de variations, concentrées, quoique dans un ordre différent dû à la spécificité de la tâche, sur les mêmes zones de fragilité orthographique que celles dégagées par Pach, Jacquemin, Millet et Billiez (1994 : les diacritiques et auxiliaires d’écriture, les morphogrammes non verbaux de nombre et les lettres dérivatives ainsi que les morphogrammes verbaux, particulièrement l’accord du participe passé avec avoir ou les finales en /E/.

    Full Text Available As patients become increasingly involved in their medical care, physician-patient communication gains importance. A previous study showed that physician self-disclosure (SD of personal information by primary care providers decreased patient rating of the provider communication skills. The objective of this study was to explore the incidence and impact of emergency department (ED provider self-disclosure on patients’ rating of provider communication skills. A survey was administered to 520 adult patients or parents of pediatric patients in a large tertiary care ED during the summer of 2014. The instrument asked patients whether the provider self-disclosed and subsequently asked patients to rate providers’ communication skills. We compared patients’ ratings of communication measurements between encounters where self-disclosure occurred to those where it did not. Patients reported provider SD in 18.9% of interactions. Provider SD was associated with more positive patient perception of provider communication skills (p<0.05, more positive ratings of provider rapport (p<0.05 and higher satisfaction with provider communication (p<0.05. Patients who noted SD scored their providers’ communication skills as “excellent” (63.4% compared to patients without selfdisclosure (47.1%. Patients reported that they would like to hear about their providers’ experiences with a similar chief complaint (64.4% of patients, their providers’ education (49%, family (33%, personal life (21% or an injury/ailment unlike their own (18%. Patients responded that providers self-disclose to make patients comfortable/at ease and to build rapport. Provider self-disclosure in the ED is common and is associated with higher ratings of provider communication, rapport, and patient satisfaction. [West J Emerg Med. 2017;18(143-49.

    Berlin, Anita; Törnkvist, Lena; Hylander, Ingrid

    2010-07-20

    Worldwide, multicultural interaction within health care seems to be challenging and problematic. This is also true among Primary Child Health Care nurses (PCHC nurses) in the Swedish Primary Child Health Care services (PCHC services). Therefore, there was a need to investigate the parents' perspective in-depth. The aim of the study was to construct a theoretical model that could promote further understanding of the variety of experiences of parents of foreign origin regarding their interaction with the PCHC nurses at PCHC services. The study used Grounded Theory Methodology. Twenty-one parents of foreign origin in contact with PCHC servicies were interviewed. In our study parents were watchfully checking rapport, i.e. if they could perceive sympathy and understanding from the PCHC nurses. This was done by checking the nurse's demeanour and signs of judgement. From these interviews we created a theoretical model illustrating the interactive process between parents and PCHC nurses. We found it to be of utmost importance for parents to be certain that it was possible to establish rapport with the PCHC nurse. If not, disruptions in the child's attendance at PCHC services could result.

    Preventing health care-associated infections is essential to the safety and quality of health care. Although patients' experience of care under isolation is well established, little is known of health care workers' experiences when providing such care. This study explored the health professionals; lived experience of caring for patients under transmission-based precautions. Interpretive phenomenology was used to examine 12 health care professionals' lived experience of providing care under transmission-based precautions in 3 health care facilities in Australia. Data were obtained from in-depth interviews and observations of health professionals. The essential phenomena of "recognizing rapport" represented the health professionals' lived experience. Three themes emerged starting with (1) relationships with others, their rapport and communication with patients, patients' families and visitors, and colleagues. These relationships are influenced by (2) barriers to practice, such as personal level of comfort when wearing personal protective equipment, physical limitations of the environment, and management of workload and resources. Such barriers influence (3) patient outcomes, namely the quality of the care provided and adverse events. In the context of caring for patients under transmission-based precautions, the relationships between health professionals and their patients are critical to the quality and safety of health care with respect to infection prevention and control.

Dans cette étude, un modèle de prédiction de durée de vie est proposé permettant d’évaluer le nombre de cycles de fatigue avant dommage en fonction de la contrainte appliquée, de la densité osseuse et de l’âge du spécimen. Vu leur grande dispersion, les résultats des essais de fatigue publiés par Brinckmann (1988 ont été classifiés afin de pouvoir être analysés par la méthode des plans d’expériences. Un modèle non linéaire présentant un coefficient de détermination R2 de 94 % est établi. En comparant les valeurs prédites par ce modèle avec les résultats des essais de fatigue de Hansson (1987, on constate une certaine cohérence entre les résultats. Cette étude justifie l’hypothèse que la densité osseuse et l’âge outre la contrainte appliquée ont un effet sur la fatigue du rachis.Due to vertebral densimetric and structural inhomogeneity between individuals and the fact that bone strength varies with bone density and discontinuities within the trabecular lattice which changes with age, vertebral fatigue behavior cannot be considered as depending only on the cyclic stress. In this study, a lifetime prediction model is proposed for evaluating the number of cycles before damage as a function of the cyclic stress, bone density and age of the specimen. Due to their large dispersion, the results of the fatigue tests published by Brinckmann (1988 have been classified for analysis using the experiment design method.

Discrepancies with other workers results for single-contact dissolution experiments can be explained in terms of differences in experimental configuration and competition between driving forces. La dissolution sous contrainte (IPS - Intergranular Pressure Solution représente un mécanisme de lithification, de compaction et de déformation à l'échelle géologique pour une large gamme de roches.

    Developing technologies to reduce the rate of increase of atmospheric concentration of carbon dioxide (CO2) from annual emissions of 8.6PgCyr-1 from energy, process industry, land-use conversion and soil cultivation is an important issue of the twenty-first century. Of the three options of reducing the global energy use, developing low or no-carbon fuel and sequestering emissions, this manuscript describes processes for carbon (CO2) sequestration and discusses abiotic and biotic technologies. Carbon sequestration implies transfer of atmospheric CO2 into other long-lived global pools including oceanic, pedologic, biotic and geological strata to reduce the net rate of increase in atmospheric CO2. Engineering techniques of CO2 injection in deep ocean, geological strata, old coal mines and oil wells, and saline aquifers along with mineral carbonation of CO2 constitute abiotic techniques. These techniques have a large potential of thousands of Pg, are expensive, have leakage risks and may be available for routine use by 2025 and beyond. In comparison, biotic techniques are natural and cost-effective processes, have numerous ancillary benefits, are immediately applicable but have finite sink capacity. Biotic and abiotic C sequestration options have specific nitches, are complementary, and have potential to mitigate the climate change risks.

    Carbon aerogels used as a binder for granularized materials, including other forms of carbon and metal additives, are cast onto carbon or metal fiber substrates to form composite carbon thin film sheets. The thin film sheets are utilized in electrochemical energy storage applications, such as electrochemical double layer capacitors (aerocapacitors), lithium based battery insertion electrodes, fuel cell electrodes, and electrocapacitive deionization electrodes. The composite carbon foam may be formed by prior known processes, but with the solid particles being added during the liquid phase of the process, i.e. prior to gelation. The other forms of carbon may include carbon microspheres, carbon powder, carbon aerogel powder or particles, graphite carbons. Metal and/or carbon fibers may be added for increased conductivity. The choice of materials and fibers will depend on the electrolyte used and the relative trade off of system resistivty and power to system energy.

    Post-infectious encephalitis/encephalopathy is a neurological syndrome that sometimes develops following common viral or bacterial infections. The most common form is acute disseminated encephalomyelitis (ADEM). ADEM is a demyelinating disease of the central nervous system that typically presents as a monophasic disorder associated with multifocal neurologic symptoms and encephalitis. Anti-N-methyl-d-aspartate receptor (anti-NMDAR) encephalitis is another type of severe autoimmune disorder, characterized by seizures, movement disorders and psychiatric symptoms. In general, the prognosis and long-term outcomes of both ADEM and anti-NMDAR encephalitis are favorable. Most patients show complete, albeit slow recovery over a period of one to 2 years. There are few reports of patients with these disorders showing long-term residual psychiatric symptoms. We report the case of a 16-year-old Japanese male who suffered from acute post-infectious encephalitis. The patient followed an atypical recovery course, in that he showed poor rapport, lack of spontaneity and passive social withdrawal for more than 2 years after the initial symptoms. While treatment with small doses of antipsychotic drugs at the hospital had no effect on the symptoms, the patient recovered gradually over a prolonged period of five or so years. This case report suggests that a type of acute post-infectious encephalitis with demyelinating features, possibly ADEM or anti-NMDAR encephalitis, or an overlap between the two, can cause a prodrome of behavioral changes and long-term residual psychiatric symptoms for many months, although it is eventually associated with a good prognosis.

    Angelova, Polina; Gölzhäuser, Armin

    2017-03-01

    This chapter describes the formation and properties of one nanometer thick carbon nanomembranes (CNMs), made by electron induced cross-linking of aromatic self-assembled monolayers (SAMs). The cross-linked SAMs are robust enough to be released from the surface and placed on solid support or over holes as free-standing membranes. Annealing at 1000K transforms CNMs into graphene accompanied by a change of mechanical stiffness and electrical resistance. The developed fabrication approach is scalable and provides molecular level control over thickness and homogeneity of the produced CNMs. The mechanisms of electron-induced cross-linking process are discussed in details. A variety of polyaromatic thiols: oligophenyls as well as small and extended condensed polycyclic hydrocarbons have been successfully employed, demonstrating that the structural and functional properties of the resulting nanomembranes are strongly determined by the structure of molecular monolayers. The mechanical properties of CNMs (Young's modulus, tensile strength and prestress) are characterized by bulge testing. The interpretation of the bulge test data relates the Young's modulus to the properties of single molecules and to the structure of the pristine SAMs. The gas transport through the CNM is measured onto polydimethylsiloxane (PDMS) - thin film composite membrane. The established relationship of permeance and molecular size determines the molecular sieving mechanism of permeation through this ultrathin sheet.

  12. Radiation damage in carbon-carbon composites

    Graphite and carbon-carbon composite materials are widely used in plasma facing applications in current Tokamak devices such as TFTR and DIIID in the USA, JET, Tore Supra and TEXTOR in Europe, and JT-60U in Japan. Carbon-carbon composites are attractive choices for Tokamak limiters and diverters because of their low atomic number, high thermal shock resistance, high melting point, and high thermal conductivity. Next generation machines such as the International Thermonuclear Experimental Reactor (ITER) will utilize carbon-carbon composites in their first wall and diverter. ITER will be an ignition machine and thus will produce substantial neutron fluences from the D-T fusion reaction. The resultant high energy neutrons will cause carbon atom displacements in the plasma facing materials which will markedly affect their structure and physical properties. The effect of neutron damage on graphite has been studied for over forty years. Recently the effects of neutron irradiation on the fusion relevant graphite GraphNOL N3M was reviewed. In contrast to graphite, relatively little work has been performed to elucidate the effects of neutron irradiation on carbon-carbon composites. The results of our previous irradiation experiments have been published elsewhere. Here the irradiation induced dimensional changes in 1D, 2D, and 3D carbon-carbon composites are reported for fluences up to 4.7 dpa at an irradiation temperature of 600 degree C

  13. From carbon nanotubes to carbon atomic chains

    Carbyne is a linear allotrope of carbon. It is formed by a linear arrangement of carbon atoms with sp-hybridization. We present a reliable and reproducible experiment to obtain these carbon atomic chains using few-layer-graphene (FLG) sheets and a HRTEM. First the FLG sheets were synthesized from worm-like exfoliated graphite and then drop-casted on a lacey-carbon copper grid. Once in the TEM, two holes are opened near each other in a FLG sheet by focusing the electron beam into a small spot. Due to the radiation, the carbon atoms rearrange themselves between the two holes and form carbon fibers. The beam is concentrated on the carbon fibers in order excite the atoms and induce a tension until multi wall carbon nanotube (MWCNT) is formed. As the radiation continues the MWCNT breaks down until there is only a single wall carbon nanotube (SWCNT). Then, when the SWCNT breaks, an atomic carbon chain is formed, lasts for several seconds under the radiation and finally breaks. This demonstrates the stability of this carbon structure.

    This report for the Swiss Federal Office of Energy presents in tables and diagrams the results of a survey involving 421 households in Switzerland, about their awareness to energy issues and, in particular, to all what regards wind energy and wind power plants. Globally, 80% of the persons asked for their opinion believe that electric power demand will continue to increase. 66% of them are in favour of increased use of renewable energy sources and would consequently agree with a 10% more expensive end-user energy price. 89% of the persons taking part to the survey approve the installation of wind energy farms in Switzerland. Moreover, statistics indicates that the households living in regions already equipped with wind farms are significantly more favorable to the creation of new wind energy sites than those not living in these regions. By the end of the day, it turns out that the main reasons for accepting wind energy are environmental concerns as well as the fear of being obliged to use nuclear power. [French] Ce rapport presente par des graphiques et des tableaux le resultat d'un sondage d'opinion aupres de 421 menages en Suisse, sur la sensibilite du public aux problemes de l'energie et plus particulierement sur sa perception de tout ce qui concerne l'energie du vent et son exploitation par l'implantation d'eoliennes. Globalement, 80% des menages pensent que la demande d'energie electrique va poursuivre sa croissance. 66% d'entre eux sont favorables au developpement des energies renouvelables et prets a accepter en consequence une augmentation du prix de l'energie allant jusqu'a 10%. 89% des personnes interrogees sont favorables au developpement des eoliennes en Suisse.

    The purpose of this study was to examine the effect of music therapy interventions utilizing two types of touch, expressive touch and instrumental touch, on the behavior states of older adults who have late-stage dementia of the Alzheimer's type. A secondary purpose of this study was to examine the perceived effectiveness of the music therapist when expressive and instrumental touch was employed during music therapy sessions. A within-subject design was used with 9 participants receiving 3 sessions in each of the experimental conditions: no touch, expressive touch, and instrumental touch. Results of a one-way ANOVA revealed that expressive touch was significantly more effective during the initial session in eliciting and maintaining alert behavior states than the instrumental and control conditions; however, there were no significant differences between the experimental and control conditions during the first and second session repetitions. Rapport ratings revealed that the therapist's client rapport was perceived to be significantly higher during both the expressive touch and instrumental touch conditions than during the control condition. These findings have important implications for music therapy practice and the effective use of nonverbal communication.

    1985-12-01

    Young people are very often confined to a form of `participation' tailored for them by the adult section of society. This article deals with the situation of youth who are constantly caught up between their creativity potential and official rhetoric about youth, the nightmarish spectre of `the crisis', and the inability of adults to create for themselves an identity and to question the mechanisms of division and exclusion set up by societies in order to protect themselves. Despite these constraints, often structured in a very subtle way, young people are discovering in international life, in existing educational institutions, in work and in the cultural sphere alternative forms of action, communication and solidarity which are able to respond or to provide solutions to the problems of society.

    Bulk-carbonate carbon isotope ratios are a widely applied proxy for investigating the ancient biogeochemical carbon cycle. Temporal carbon isotope trends serve as a prime stratigraphic tool, with the inherent assumption that bulk micritic carbonate rock is a faithful geochemical recorder of the isotopic composition of seawater dissolved inorganic carbon. However, bulk-carbonate rock is also prone to incorporate diagenetic signals. The aim of the present study is to disentangle primary trends from diagenetic signals in carbon isotope records which traverse the Permian-Triassic boundary in the marine carbonate-bearing sequences of Iran and South China. By pooling newly produced and published carbon isotope data, we confirm that a global first-order trend towards depleted values exists. However, a large amount of scatter is superimposed on this geochemical record. In addition, we observe a temporal trend in the amplitude of this residual δ13C variability, which is reproducible for the two studied regions. We suggest that (sub-)sea-floor microbial communities and their control on calcite nucleation and ambient porewater dissolved inorganic carbon δ13C pose a viable mechanism to induce bulk-rock δ13C variability. Numerical model calculations highlight that early diagenetic carbonate rock stabilization and linked carbon isotope alteration can be controlled by organic matter supply and subsequent microbial remineralization. A major biotic decline among Late Permian bottom-dwelling organisms facilitated a spatial increase in heterogeneous organic carbon accumulation. Combined with low marine sulfate, this resulted in varying degrees of carbon isotope overprinting. A simulated time series suggests that a 50 % increase in the spatial scatter of organic carbon relative to the average, in addition to an imposed increase in the likelihood of sampling cements formed by microbial calcite nucleation to 1 out of 10 samples, is sufficient to induce the observed signal of carbon

  14. Carbon-14 waste management

    1984-01-01

    Carbon-14 occurs in nature, but is also formed in nuclear reactors. Because of its long half-life and the biological significance of carbon, releases from nuclear facilities could have a significant radiological impact. Waste management strategies for carbon-14 are therefore of current concern. Carbon-14 is present in a variety of waste streams both at reactors and at reprocessing plants. A reliable picture of the production and release of carbon-14 from various reactor systems has been built up for the purposes of this study. A possible management strategy for carbon-14 might be the reduction of nitrogen impurity levels in core materials, since the activation of 14 N is usually the dominant source of carbon-14. The key problem in carbon-14 management is its retention of off-gas streams, particularly in the dissolver off-gas stream at reprocessing plants. Three alternative trapping processes that convert carbon dioxide into insoluble carbonates have been suggested. The results show that none of the options considered need be rejected on the grounds of potential radiation doses to individuals. All exposures should be as low as reasonably achievable, economic and social factors being taken into account. If, on these grounds, retention and disposal of carbon-14 is found to be beneficial, then, subject to the limitations noted, appropriate retention, immobilization and disposal technologies have been identified

    In the first volume: This report is a description of the reactor Pegase, given with a view to examine the safety of the installations. The Cadarache site at which they are situated is briefly described, in particular because of the consequences on the techniques employed for building Pegase. A description is also given of the original aspects of the reactor. The independent loops which are designed for full-scale testing of fuel elements used in natural uranium-gas-graphite reactor systems are described in this report, together with their operational and control equipment. In the second volume: In the present report are examined the accidents which could cause damage to the Pegase reactor installation. Among possible causes of accidents considered are the seismicity of the region, an excessive power excursion of the reactor and a fracture in the sealing of an independent loop. Although all possible precautions have been taken to offset the effects of such accidents, their ultimate consequences are considered here. The importance is stressed of the security action and regulations which, added to the precautions taken for the construction, ensure the safety of the installations.

La documentation archivistique de l’Algérie ottomane est globalement peu fournie, ce qui amène à réfléchir sur la pratique historienne dans ces conditions. Non pas en cherchant ailleurs ce que ces archives ne fourniraient pas, mais plutôt en interrogeant plus précisément le sens et les usages sociaux de leur matérialité. Il s’agit dès lors d’en saisir les conditions de production au regard de leur contenu, et de les interpeller comme autant de contextes ponctuels au sein et à l’articulation desquels se déploient et s’affirment des actions. Derrière cette approche se profilent les questions de savoir en quoi peut bien vouloir consister de produire des documents et d’archiver des documents, autant d’opérations à l’issue desquelles les historiens opèrent, et qui cependant ne s’imposent pas d’emblée. À l’analyse de la configuration archivistique de l’Algérie ottomane, j’explorerai ces questions en présentant deux axes de recherches qui m’ont mobilisée. D’une part en interrogeant les effets de l’histoire (coloniale de ces archives sur le sens de leur contenu. D’autre part en présentant les résultats d’une recherche collective autour des conditions de production d’un type de source classique pour les ottomanistes, les registres de cadis.On the Archives of Ottoman Algeria.

    Basic concepts of the global carbon cycle on earth are described; by careful analyses of isotopic ratios, emission history and oceanic ventilation rates are derived, which provide crucial tests for constraining and calibrating models. Effects of deforestation, fertilizing, fossil fuel burning, soil erosion, etc. are quantified and compared, and the oceanic carbon process is evaluated. Oceanic and terrestrial biosphere modifications are discussed and a carbon cycle model is proposed

  2. Changing global carbon cycle

    2007-01-01

    Full text: The increase in atmospheric carbon dioxide (C02) is the single largest human perturbation on the earth's radiative balance contributing to climate change. Its rate of change reflects the balance between anthropogenic carbon emissions and the dynamics of a number of terrestrial and ocean processes that remove or emit C02. It is the long term evolution of this balance that will determine to large extent the speed and magnitude of the human induced climate change and the mitigation requirements to stabilise atmospheric C02 concentrations at any given level. In this talk, we show new trends in global carbon sources and sinks, with particularly focus on major shifts occurring since 2000 when the growth rate of atmospheric C02 has reached its highest level on record. The acceleration in the C02 growth results from the combination of several changes in properties of the carbon cycle, including: acceleration of anthropogenic carbon emissions; increased carbon intensity of the global economy, and decreased efficiency of natural carbon sinks. We discuss in more detail some of the possible causes of the reduced efficiency of natural carbon sinks on land and oceans, such as the decreased net sink in the Southern Ocean and on terrestrial mid-latitudes due to world-wide occurrence of drought. All these changes reported here characterise a carbon cycle that is generating stronger than expected climate forcing, and sooner than expected

  4. Carbon emissions in China

    Energy Technology Data Exchange (ETDEWEB)

    Liu, Zhu [Harvard Univ., Cambridge, MA (United States). Sustainability Science Program

    2016-07-01

    This study analyzes the spatial-temporal pattern and processes of China's energy-related carbon emissions. Based on extensive quantitative analysis, it outlines the character and trajectory of China's energy-related carbon emissions during the period 1995-2010, examining the distribution pattern of China's carbon emissions from regional and sectoral perspectives and revealing the driving factors of China's soaring emission increase. Further, the book investigates the supply chain carbon emissions (the carbon footprints) of China's industrial sectors. Anthropogenic climate change is one of the most serious challenges currently facing humankind. China is the world's largest developing country, top primary energy consumer and carbon emitter. Achieving both economic growth and environmental conservation is the country's twofold challenge. Understanding the status, features and driving forces of China's energy-related carbon emissions is a critical aspect of attaining global sustainability. This work, for the first time, presents both key findings on and a systematic evaluation of China's carbon emissions from energy consumption. The results have important implications for global carbon budgets and burden-sharing with regard to climate change mitigation. The book will be of great interest to readers around the world, as it addresses a topic of truly global significance.

  5. Microbially mediated mineral carbonation

    Science.gov (United States)

    Power, I. M.; Wilson, S. A.; Dipple, G. M.; Southam, G.

    2010-12-01

    Mineral carbonation involves silicate dissolution and carbonate precipitation, which are both natural processes that microorganisms are able to mediate in near surface environments (Ferris et al., 1994; Eq. 1). (Ca,Mg)SiO3 + 2H2CO3 + H2O → (Ca,Mg)CO3 + H2O + H4SiO4 + O2 (1) Cyanobacteria are photoautotrophs with cell surface characteristics and metabolic processes involving inorganic carbon that can induce carbonate precipitation. This occurs partly by concentrating cations within their net-negative cell envelope and through the alkalinization of their microenvironment (Thompson & Ferris, 1990). Regions with mafic and ultramafic bedrock, such as near Atlin, British Columbia, Canada, represent the best potential sources of feedstocks for mineral carbonation. The hydromagnesite playas near Atlin are a natural biogeochemical model for the carbonation of magnesium silicate minerals (Power et al., 2009). Field-based studies at Atlin and corroborating laboratory experiments demonstrate the ability of a microbial consortium dominated by filamentous cyanobacteria to induce the precipitation of carbonate minerals. Phototrophic microbes, such as cyanobacteria, have been proposed as a means for producing biodiesel and other value added products because of their efficiency as solar collectors and low requirement for valuable, cultivable land in comparison to crops (Dismukes et al., 2008). Carbonate precipitation and biomass production could be facilitated using specifically designed ponds to collect waters rich in dissolved cations (e.g., Mg2+ and Ca2+), which would allow for evapoconcentration and provide an appropriate environment for growth of cyanobacteria. Microbially mediated carbonate precipitation does not require large quantities of energy or chemicals needed for industrial systems that have been proposed for rapid carbon capture and storage via mineral carbonation (e.g., Lackner et al., 1995). Therefore, this biogeochemical approach may represent a readily

    The regeneration process was tested by oxidative treatment of activated carbon, employable in the vodka industry, with an aqueous KMnO/sub 4/ (I) solution. The spent carbon is exposed to a 0.4% solution of for 30-50 min, then washed with water, and blown through for 15-30 min with steam at a temperature of 105-110/sup 0/ C under 0.07 MPa pressure. A check of the activity of the regenerated carbon revealed an increase in pore volume by 29% with respect to benzene adsorption and a higher adsorptive capacity (by a factor of about 2) with respect to fatty acids by comparison with carbon regenerated by the conventional steam procedure. Application of the process in the plant made it possible to use the carbon for 3-4 months additionally because of an increase in activity after regeneration. Iodine comsumption amounts to 5-6 kg per column.

  18. The Contemporary Carbon Cycle

    Science.gov (United States)

    Houghton, R. A.

    2003-12-01

    The global carbon cycle refers to the exchanges of carbon within and between four major reservoirs: the atmosphere, the oceans, land, and fossil fuels. Carbon may be transferred from one reservoir to another in seconds (e.g., the fixation of atmospheric CO2 into sugar through photosynthesis) or over millennia (e.g., the accumulation of fossil carbon (coal, oil, gas) through deposition and diagenesis of organic matter). This chapter emphasizes the exchanges that are important over years to decades and includes those occurring over the scale of months to a few centuries. The focus will be on the years 1980-2000 but our considerations will broadly include the years ˜1850-2100. Chapter 8.09, deals with longer-term processes that involve rates of carbon exchange that are small on an annual timescale (weathering, vulcanism, sedimentation, and diagenesis).The carbon cycle is important for at least three reasons. First, carbon forms the structure of all life on the planet, making up ˜50% of the dry weight of living things. Second, the cycling of carbon approximates the flows of energy around the Earth, the metabolism of natural, human, and industrial systems. Plants transform radiant energy into chemical energy in the form of sugars, starches, and other forms of organic matter; this energy, whether in living organisms or dead organic matter, supports food chains in natural ecosystems as well as human ecosystems, not the least of which are industrial societies habituated (addicted?) to fossil forms of energy for heating, transportation, and generation of electricity. The increased use of fossil fuels has led to a third reason for interest in the carbon cycle. Carbon, in the form of carbon dioxide (CO2) and methane (CH4), forms two of the most important greenhouse gases. These gases contribute to a natural greenhouse effect that has kept the planet warm enough to evolve and support life (without the greenhouse effect the Earth's average temperature would be -33

    The utilization of carbon dioxide for the production of valuable chemicals via catalysts is one of the efficient ways to mitigate the greenhouse gases in the atmosphere. It is known that the carbon dioxide conversion and product yields are still low even if the reaction is operated at high pressure and temperature. The carbon dioxide utilization and conversion provides many challenges in exploring new concepts and opportunities for development of unique catalysts for the purpose of activating the carbon dioxide molecules. In this paper, the role of carbon-based nanocatalysts in the hydrogenation of carbon dioxide and direct synthesis of dimethyl carbonate from carbon dioxide and methanol are reviewed. The current catalytic results obtained with different carbon-based nanocatalysts systems are presented and how these materials contribute to the carbon dioxide conversion is explained. In addition, different strategies and preparation methods of nanometallic catalysts on various carbon supports are described to optimize the dispersion of metal nanoparticles and catalytic activity.

    Nanoscale multifunctional carbon probes facilitate cellular studies due to their small size, which makes it possible to interrogate organelles within living cells in a minimally invasive fashion. However, connecting nanotubes to macroscopic devices and constructing an integrated system for the purpose of fluid and electrical signal transfer is challenging, as is often the case with nanoscale components. We describe a non-catalytic chemical vapor deposition based method for batch fabrication of integrated multifunctional carbon nanopipettes (CNPs) with tip diameters much smaller (10-30 nm) than previously reported (200 nm and above) and approaching those observed for multiwalled carbon nanotubes. This eliminates the need for complicated attachment/assembly of nanotubes into nanofluidic devices. Variable tip geometries and structures were obtained by controlled deposition of carbon inside and outside quartz pipettes. We have shown that the capillary length and gas flow rate have a marked effect on the carbon deposition. This gives us a flexible protocol, useful for growing carbon layers of different thicknesses at selective locations on a glass pipette to yield a large variety of cellular probes in bulk quantities. The CNPs possess an open channel for fluid transfer with the carbon deposited inside at 875 °C behaving like an amorphous semiconductor. Vacuum annealing of the CNP tips at temperatures up to 2000 °C yields graphitic carbon structures with an increase in conductivity of two orders of magnitude. Penetration of the integrated carbon nanoprobes into cells was shown to produce minimal Ca2+ signals, fast recovery of basal Ca2+ levels and no adverse activation of the cellular metabolism during interrogation times as long as 0.5-1 h.

    2012-08-01

    A recent resurgence in basic and applied research on photosynthesis has been driven in part by recognition that fulfilling future food and energy requirements will necessitate improvements in crop carbon-fixation efficiencies. Photosynthesis in traditional terrestrial crops is being reexamined in light of molecular strategies employed by photosynthetic microbes to enhance the activity of the Calvin cycle. Synthetic biology is well-situated to provide original approaches for compartmentalizing and enhancing photosynthetic reactions in a species independent manner. Furthermore, the elucidation of alternative carbon-fixation routes distinct from the Calvin cycle raises possibilities that novel pathways and organisms can be utilized to fix atmospheric carbon dioxide into useful materials.

    The paper describes the procedures used at the Structures Test Laboratory of the Wright Laboratory's Flight Dynamics Directorate to test a carbon/carbon hot structure representing a typical hypersonic gliding body, and presents the results of tests. The forebody was heated to 1371 C over 13 test runs, using radiant quartz lamps; a vertical shear force of 5.34 kN was introduced to the nose at a stabilized temperature of 816 C. Test data were collected using prototype high-temperature strain gages, in-house-designed high-temperature extensometers, conventional strain gages, and thermocouples. Video footage was taken of all test runs. Test runs were successfully completed up to 1371 C with flight typical thermal gradients at heating rates up to 5.56 C/sec. Results showed that, overall, the termal test control systems performed as predicted and that test temperatures and thermal gradients were achieved to within about 5 percent in most cases.

  7. Authigenic carbonate and the history of the global carbon cycle.

    Science.gov (United States)

    Schrag, Daniel P; Higgins, John A; Macdonald, Francis A; Johnston, David T

    2013-02-01

    We present a framework for interpreting the carbon isotopic composition of sedimentary rocks, which in turn requires a fundamental reinterpretation of the carbon cycle and redox budgets over Earth's history. We propose that authigenic carbonate, produced in sediment pore fluids during early diagenesis, has played a major role in the carbon cycle in the past. This sink constitutes a minor component of the carbon isotope mass balance under the modern, high levels of atmospheric oxygen but was much larger in times of low atmospheric O(2) or widespread marine anoxia. Waxing and waning of a global authigenic carbonate sink helps to explain extreme carbon isotope variations in the Proterozoic, Paleozoic, and Triassic.

  18. L’excès de l’état par rapport à la situation dans L’être et l’événement de A. Badiou

    2006-05-01

    Full Text Available Cet article est une discussion de l’ouvrage de A. Badiou, L’être et l’événement, autour de la question du rapport de l’état (et de l’Etat à la situation. Nous commençons par rappeler la place que donne A. Badiou aux mathématiques dans son dispositif. Nous parcourons ensuite L’être et l’événement en prenant comme fil directeur cette question, du rapport de l’état à la situation. La dernière partie compare la position de A. Badiou à la tradition « épistémologique » en France et, en particulier, aux textes de Jean Cavaillès, dont A. Badiou se réclame à plusieurs reprises. L’originalité de A. Badiou dans cette tradition est sans doute sa rupture avec la perspective historique mais le problème, que cette confrontation pose, est de savoir s’il est en effet possible de couper les théories mathématiques de leur histoire, comme A. Badiou doit le faire.This paper concerns A. Badiou’s treaty, L’être et l’évenement, and the question of the relationship between “state” and “situation”. We first discuss the role that is given to mathematics in A. Badiou’s philosophy. We then read rather extensively L’être et l’événement, following our problem, the relationship between “state” and “situation”. In the last part, we compare A. Badiou’s position to the tradition of “epistemology” in France, using in particular Cavaillès’ writings. A. Badiou appears to dissociate himself from the historical perspective that made the core of this tradition of epistemology since Brunschvicg. But the problem is whether one can indeed separate mathematical theories from their history and their context, as A. Badiou, or “Badiouism”, is bound to do.

    The climate challenge appeals to an unprecedented mutation of our societies. From north to south, all our life styles will have to be changed from dwelling, to transport and feeding. These changes will have sense only at a worldwide scale and will impact our way of development. How can we reduce our energy consumption and greenhouse impact with answering everyone's essential needs at the same time? How can we invent a carbon-free economy in the North and preserve the big socio-economical equilibria at the same time? How can we get rid of poverty in the South without compromising the well-being of the future generations with an increase of CO 2 emissions? Such difficulties cannot be overcome without innovations in terms of public policies. This book takes stock of the new possible instruments and policies at the global scale and involving fiscality, standards, investments and social justice. Content: 1 - the carbon threat: a changing climate and energies becoming scarce (the climate threat, an increasing energy insecurity); carbon and modern economy (human greenhouse gas emissions, a carbon-free well-being); governments and carbon control (a global challenge requiring an international control, the experiments era from Rio to the present day, the challenge of the state in front of the carbon threat); 2 - the political instruments of environment: standards as first instruments of climate public policies (standards efficiency in some sectors, standards limitations, standards and innovation); emissions quotas and market instruments (Kyoto protocol and CO 2 market, the future of 'cap and trade' and of individual and regional quotas); carbon tax, fiscal instruments and new regulations (carbon tax as an alternative or a complement, other fiscal and para-fiscal instruments, new regulation instruments); investing in climate (managing the transition, governments as transition administrators).

    Carbon nanotubes have created a great deal of excitement in the Materials Science community because of their outstanding mechanical, electrical, and thermal properties. Use of carbon nanotubes as reinforcements for polymers could lead to a new class of composite materials with properties, durability, and performance far exceeding that of conventional fiber reinforced composites. Organized arrays of carbon nanotubes, e.g., nanotube monolayers, could find applications as thermal management materials, light emitting devices, and sensor arrays. Carbon nanotubes could also be used as templates upon which nanotubes from other materials could be constructed. Successful use of carbon nanotubes in any of these potential applications requires the ability to control the interactions of nanotubes with each other and with other materials, e.g., a polymer matrix. One approach to achieving this control is to attach certain chemical groups to the ends and/or side-walls of the nanotubes. The nature of these chemical groups can be varied to achieve the desired result, such as better adhesion between the nanotubes and a polymer. Under a joint program between NASA Glenn, Clark Atlanta University, and Rice University researchers are working on developing a chemistry "tool-kit" that will enable the functionalization of carbon nanotubes with a variety of chemical groups. Recent results of this effort will be discussed.

    This is the final report of a one-year, Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The project objective was to evaluate the use of carbon/carbon-fiber-reinforced composites for use in endoprosthetic devices. The application of these materials for the metacarpophalangeal (MP) joints of the hand was investigated. Issues concerning mechanical properties, bone fixation, biocompatibility, and wear are discussed. A system consisting of fiber reinforced materials with a pyrolytic carbon matrix and diamond-like, carbon-coated wear surfaces was developed. Processes were developed for the chemical vapor infiltration (CVI) of pyrolytic carbon into porous fiber preforms with the ability to tailor the outer porosity of the device to provide a surface for bone in-growth. A method for coating diamond-like carbon (DLC) on the articulating surface by plasma-assisted chemical vapor deposition (CVD) was developed. Preliminary results on mechanical properties of the composite system are discussed and initial biocompatibility studies were performed.

    Carbon nanomaterials such as carbon nanotube and graphene are promising candidates for next-generation flexible electronics. However, the practical application of carbon electronics requires controlled fabrication of those materials with micro-patterned structures on flexible substrate at wafer-scale and low cost. Inspiring from the conventional photolithography process and pyrolysis of photoresist, herein, we demonstrate the synthesis of high-quality micro-patterned high crystallinity carbon. The method employed pre-patterned pyrolyzed photoresist as carbon precursors, in order to minimize the mobility of carbon during the high temperature growth, which results into high quality carbon patterns with a lateral resolution up to ~2 µm. The flexible carbon electronics are demonstrated by transferring the as-patterned high crystallinity carbon patterns to the flexible substrate, and showing asymmetric tensile-compressive response with high output resolution. These results will pave the way to the next-generation carbon-based flexible electronics and mechanical sensors.

    Global climate change and inequality are inescapably linked both in terms of who contributes climate change and who suffers the consequences. This fact is also partly reflected in two United Nations (UN) processes: on the one hand, the Paris Agreement of the UN Framework Convention on Climate Change under which countries agreed to hold the increase in the global average temperature to below 2 C above pre-industrial levels and, on the other hand, the UN's Sustainable Development Goals aiming to end poverty. These agreements are seen as important foundation to put the world nations on a sustainable pathway. However, how these agreements can be achieved or whether they are even mutually compatible is less clear. We explore the global carbon inequality between and within countries and the carbon implications of poverty alleviation by combining detailed consumer expenditure surveys for different income categories for a wide range of countries with an environmentally extended multi-regional input-output approach to estimate carbon footprints of different household groups, globally, and assess the carbon implications of moving the poorest people out of poverty. Given the current context, increasing income leads to increasing carbon footprints and makes global targets for mitigating greenhouse gases more difficult to achieve given the pace of technological progress and current levels of fossil fuel dependence. We conclude that the huge level of carbon inequality requires a critical discussion of undifferentiated income growth. Current carbon-intensive lifestyles and consumption patterns need to enter the climate discourse to a larger extent. (orig.)

  17. Carbon dioxide and climate

    International Nuclear Information System (INIS)

    1991-10-01

    Global climate change is a serious environmental concern, and the US has developed ''An Action Agenda'' to deal with it. At the heart of the US effort is the US Global Change Research Program (USGCRP), which has been developed by the Committee on Earth and Environmental Sciences (CEES) of the Federal Coordinating Council for Sciences, Engineering, and Technology (FCCSET). The USGCRP will provide the scientific basis for sound policy making on the climate-change issue. The DOE contribution to the USGCRP is the Carbon Dioxide Research Program, which now places particular emphasis on the rapid improvement of the capability to predict global and regional climate change. DOE's Carbon Dioxide Research Program has been addressing the carbon dioxide-climate change connection for more than twelve years and has provided a solid scientific foundation for the USGCRP. The expansion of the DOE effort reflects the increased attention that the Department has placed on the issue and is reflected in the National Energy Strategy (NES) that was released in 1991. This Program Summary describes projects funded by the Carbon Dioxide Research Program during FY 1991 and gives a brief overview of objectives, organization, and accomplishments. The Environmental Sciences Division of the Office of Health and Environmental Research, Office of Energy Research supports a Carbon Dioxide Research Program to determine the scientific linkage between the rise of greenhouse gases in the atmosphere, especially carbon dioxide, and climate and vegetation change. One facet is the Core CO 2 Program, a pioneering program that DOE established more than 10 years ago to understand and predict the ways that fossil-fuel burning could affect atmospheric CO 2 concentration, global climate, and the Earth's biosphere. Major research areas are: global carbon cycle; climate detection and models of climate change; vegetation research; resource analysis; and, information and integration

    2013-01-29

    Data representative of a measured carbon dioxide (CO.sub.2) concentration and of a measured oxygen (O.sub.2) concentration at a measurement location can be used to determine whether the measured carbon dioxide concentration at the measurement location is elevated relative to a baseline carbon dioxide concentration due to escape of carbon dioxide from a source associated with a carbon capture and storage process. Optionally, the data can be used to quantify a carbon dioxide concentration increase at the first location that is attributable to escape of carbon dioxide from the source and to calculate a rate of escape of carbon dioxide from the source by executing a model of gas-phase transport using at least the first carbon dioxide concentration increase. Related systems, methods, and articles of manufacture are also described.

    The Dutch Office of Energy Regulation (DTe) plans to adjust the present regulations with regard to regional electricity network companies. In 2002 an integrated model for pricing and quality regulations is drafted, which is expected to be implemented in 2005. This report serves as input for such a model. Quality is defined in terms of electricity supply disruptions. The aim of the study on the title subject is to determine prices for different types of power supply disruptions. The study is based on a survey among 12,400 households and nearly 2,500 small and medium-sized businesses in the Netherlands. [Dutch] De Dienst uitvoering en Toezicht energie (DTe) is voornemens om de huidige regelgeving ten aanzien van de regionale elektriciteitsnetbedrijven aan te passen.

Dit rapport dient als input voor het kwaliteitsreguleringsmodel. Kwaliteit is hier gedefinieerd in termen van stroomonderbrekingen. Het doel van het onderzoek is om prijskaartjes vast te stellen voor verschillende soorten stroomonderbrekingen. Zo kunnen de onderbrekingskosten verschillen afhankelijk van bijvoorbeeld het tijdstip (dagdeel, dag van de week, seizoen), de duur van de onderbreking, het wel of niet ontvangen van een waarschuwing vooraf en het aantal onderbrekingen.

  4. Terrestrial Carbon Cycle Variability.

    A growing literature is reporting on how the terrestrial carbon cycle is experiencing year-to-year variability because of climate anomalies and trends caused by global change. As CO 2 concentration records in the atmosphere exceed 50 years and as satellite records reach over 30 years in length, we are becoming better able to address carbon cycle variability and trends. Here we review how variable the carbon cycle is, how large the trends in its gross and net fluxes are, and how well the signal can be separated from noise. We explore mechanisms that explain year-to-year variability and trends by deconstructing the global carbon budget. The CO 2 concentration record is detecting a significant increase in the seasonal amplitude between 1958 and now. Inferential methods provide a variety of explanations for this result, but a conclusive attribution remains elusive. Scientists have reported that this trend is a consequence of the greening of the biosphere, stronger northern latitude photosynthesis, more photosynthesis by semi-arid ecosystems, agriculture and the green revolution, tropical temperature anomalies, or increased winter respiration. At the global scale, variability in the terrestrial carbon cycle can be due to changes in constituent fluxes, gross primary productivity, plant respiration and heterotrophic (microbial) respiration, and losses due to fire, land use change, soil erosion, or harvesting. It remains controversial whether or not there is a significant trend in global primary productivity (due to rising CO 2 , temperature, nitrogen deposition, changing land use, and preponderance of wet and dry regions). The degree to which year-to-year variability in temperature and precipitation anomalies affect global primary productivity also remains uncertain. For perspective, interannual variability in global gross primary productivity is relatively small (on the order of 2 Pg-C y -1 ) with respect to a large and uncertain background (123 +/- 4 Pg-C y -1 ), and

  5. Carbon Concentration of Austenite

    Full Text Available The investigation was carried out to examine the influence of temperature and times of austempering process on the maximum extend towhich the bainite reaction can proceed and the carbon content in retained austenite. It should be noted that a small percentage change in theaustenite carbon content can have a significant effect on the subsequent austempering reaction changing the volume fraction of the phasespresent and hence, the resulting mechanical properties. Specimens were prepared from an unalloyed ductile cast iron, austenitised at 950oCfor 60 minutes and austempered by the conventional single-step austempering process at four temperatures between BS and MS, eg., 250,300, 350 and 400oC. The samples were austempered at these temperatures for 15, 30, 60, 120 and 240 minutes and finally quenched toambient temperature. Volume fractions of retained austenite and carbon concentration in the residual austenite have been observed byusing X-ray diffraction. Additionally, carbon concentration in the residual austenite was calculated using volume fraction data of austeniteand a model developed by Bhadeshia based on the McLellan and Dunn quasi-chemical thermodynamic model. The comparison ofexperimental data with the T0, T0' and Ae3' phase boundaries suggests the likely mechanism of bainite reaction in cast iron is displacive rather than diffusional. The carbon concentration in retained austenite demonstrates that at the end of bainite reaction the microstructure must consist of not only ausferrite but additionally precipitated carbides.

    This report compared the composition of samples from Wesseling and Leuna. In each case the sample was a residue from carbonization of the residues from hydrogenation of the brown coal processed at the plant. The composition was given in terms of volatile components, fixed carbon, ash, water, carbon, hydrogen, oxygen, nitrogen, volatile sulfur, and total sulfur. The result of carbonization was given in terms of (ash and) coke, tar, water, gas and losses, and bitumen. The composition of the ash was given in terms of silicon dioxide, ferric oxide, aluminum oxide, calcium oxide, magnesium oxide, potassium and sodium oxides, sulfur trioxide, phosphorus pentoxide, chlorine, and titanium oxide. The most important difference between the properties of the two samples was that the residue from Wesseling only contained 4% oil, whereas that from Leuna had about 26% oil. Taking into account the total amount of residue processed yearly, the report noted that better carbonization at Leuna could save 20,000 metric tons/year of oil. Some other comparisons of data included about 33% volatiles at Leuna vs. about 22% at Wesseling, about 5 1/2% sulfur at Leuna vs. about 6 1/2% at Leuna, but about 57% ash for both. Composition of the ash differed quite a bit between the two. 1 table.

    Polycondensation of phloroglucinol, resorcinol and formaldehyde with carbon nanotube (CNT) as the additives, using sodium carbonate as the catalyst, leads to the formation of CNT - doped carbon aerogels. The structure of carbon aerogels (CAs) with carbon nanotubes (CNTs) were characterized by X-ray diffraction and scanning electron microscopy. The specific surface area, pore size distribution and pore volume were measured by surface area analyzer. The results show that when the optimum doping dosage is 5%, the specific surface area of CNT - doped carbon aerogel is up to 665 m2 g-1 and exhibit plentiful mesoporous.

    2012-07-15

    The presence of monoethyl carbonate (MEC) in beer and sparkling wine is demonstrated for the first time, as well as the formation of this species in drinks prepared with a distilled beverage and a carbonated soft drink. A capillary electrophoresis (CE) equipment with two capacitively coupled contactless conductivity detector (C(4)D) was used to identify and quantify this species. The concentrations of MEC in samples of lager beer and rum and cola drink were, respectively, 1.2 and 4.1 mmol/l, which agree with the levels of ethanol and CO2 available in these products. Previous results about the kinetics of the reaction suggest that only a small amount of MEC should be formed after the ingredients of a drink are mixed. However, in all three cases (whisky and club soda; rum with cola; gin and tonic water), MEC was quickly formed, which was attributed to the low pH of the drinks. Copyright © 2012 Elsevier Ltd.

    2012-08-01

    A recent resurgence in basic and applied research on photosynthesis has been driven in part by recognition that fulfilling future food and energy requirements will necessitate improvements in crop carbon-fixation efficiencies. Photosynthesis in traditional terrestrial crops is being reexamined in light of molecular strategies employed by photosynthetic microbes to enhance the activity of the Calvin cycle. Synthetic biology is well-situated to provide original approaches for compartmentalizing and enhancing photosynthetic reactions in a species independent manner. Furthermore, the elucidation of alternative carbon-fixation routes distinct from the Calvin cycle raises possibilities that novel pathways and organisms can be utilized to fix atmospheric carbon dioxide into useful materials.

    2010-01-01

    Full Text Available Abstract As an electrical energy storage device, supercapacitor finds attractive applications in consumer electronic products and alternative power source due to its higher energy density, fast discharge/charge time, low level of heating, safety, long-term operation stability, and no disposable parts. This work reviews the recent development of supercapacitor based on carbon nanotubes (CNTs and their composites. The purpose is to give a comprehensive understanding of the advantages and disadvantages of carbon nanotubes-related supercapacitor materials and to find ways for the improvement in the performance of supercapacitor. We first discussed the effects of physical and chemical properties of pure carbon nanotubes, including size, purity, defect, shape, functionalization, and annealing, on the supercapacitance. The composites, including CNTs/oxide and CNTs/polymer, were further discussed to enhance the supercapacitance and keep the stability of the supercapacitor by optimally engineering the composition, particle size, and coverage.

  18. Flexible Carbon Aerogels

    Directory of Open Access Journals (Sweden)

    2016-09-01

    Full Text Available Carbon aerogels are highly porous materials with a large inner surface area. Due to their high electrical conductivity they are excellent electrode materials in supercapacitors. Their brittleness, however, imposes certain limitations in terms of applicability. In that context, novel carbon aerogels with varying degree of flexibility have been developed. These highly porous, light aerogels are characterized by a high surface area and possess pore structures in the micrometer range, allowing for a reversible deformation of the aerogel network. A high ratio of pore size to particle size was found to be crucial for high flexibility. For dynamic microstructural analysis, compression tests were performed in-situ within a scanning electron microscope allowing us to directly visualize the microstructural flexibility of an aerogel. The flexible carbon aerogels were found to withstand between 15% and 30% of uniaxial compression in a reversible fashion. These findings might stimulate further research and new application fields directed towards flexible supercapacitors and batteries.

    2015-05-01

    Pyrogenic carbon (PyC; includes soot, char, black carbon, and biochar) is produced by the incomplete combustion of organic matter accompanying biomass burning and fossil fuel consumption. PyC is pervasive in the environment, distributed throughout the atmosphere as well as soils, sediments, and water in both the marine and terrestrial environment. The physicochemical characteristics of PyC are complex and highly variable, dependent on the organic precursor and the conditions of formation. A component of PyC is highly recalcitrant and persists in the environment for millennia. However, it is now clear that a significant proportion of PyC undergoes transformation, translocation, and remineralization by a range of biotic and abiotic processes on comparatively short timescales. Here we synthesize current knowledge of the production, stocks, and fluxes of PyC as well as the physical and chemical processes through which it interacts as a dynamic component of the global carbon cycle.

    We use ab initio density functional calculations to study the stability, elastic properties and electronic structure of sp(2) carbon minimal surfaces with negative Gaussian curvature, called schwarzites. We focus on two systems with cubic unit cells containing 152 and 200 carbon atoms, which are metallic and very rigid. The porous schwarzite structure allows for efficient and reversible doping by electron donors and acceptors, making it a promising candidate for the next generation of alkali ion batteries. We identify schwarzite structures that act as arrays of interconnected spin quantum dots or become magnetic when doped. We introduce two interpenetrating schwarzite structures that may find their use as the ultimate super-capacitor.

    At the recent United Nations Conference held in Rio de Janeiro, a proposal was made by Italy to have surcharges be applied by OECD member countries on fossil fuels (carbon tax), primarily to fund pollution abatement technology transfer to developing countries and promote pollution abatement, energy conservation and the use of renewable energy sources in industrialized countries. This paper assesses how the application of the proposed carbon tax might be successfully combined with additional fiscal policies favouring coal gasification and reforestation so as to provide energy policy strategists of oil-importing countries with a long term economically and environmentally viable alternative to petroleum imports

    Results are presented from a bubble chamber experiment to search for anomalous mean free path (MFP) phenomena for secondary multicharged fragments (Zsub(f)=5 and 6) of the beam carbon nucleus at 4.2 GeV/c per nucleon. A total of 50000 primary interactions of carbon with propane (C 3 H 8 ) were created. Approximately 6000 beam tragments with charges Zsub(f)=5 and 6 were analyzed in detail to find out an anomalous decrease of MFP. The anomaly is observed only for secondary 12 C nuclei

    We present proof-of-concept all-carbon solar cells. They are made of a photoactive side of predominantly semiconducting nanotubes for photoconversion and a counter electrode made of a natural mixture of carbon nanotubes or graphite, connected by a liquid electrolyte through a redox reaction. The cells do not require rare source materials such as In or Pt, nor high-grade semiconductor processing equipment, do not rely on dye for photoconversion and therefore do not bleach, and are easy to fabr...

    Modest thermal annealing to 600 degree sign C of diamondlike amorphous-carbon (a-C) films grown at room temperature results in the formation of carbon nanocomposites with hardness similar to diamond. These nanocomposite films consist of nanometer-sized regions of high density a-C embedded in an a-C matrix with a reduced density of 5%-10%. We report on the evolution of density and bonding topologies as a function of annealing temperature. Despite a decrease in density, film hardness actually increases {approx}15% due to the development of the nanocomposite structure. (c) 2000 American Institute of Physics.

  7. Carbon Capture and Storage

    Carbon capture and sequestration (CCS) is the long-term isolation of carbon dioxide from the atmosphere through physical, chemical, biological, or engineered processes. This includes a range of approaches including soil carbon sequestration (e.g., through no-till farming), terrestrial biomass sequestration (e.g., through planting forests), direct ocean injection of CO{sub 2} either onto the deep seafloor or into the intermediate depths, injection into deep geological formations, or even direct conversion of CO{sub 2} to carbonate minerals. Some of these approaches are considered geoengineering (see the appropriate chapter herein). All are considered in the 2005 special report by the Intergovernmental Panel on Climate Change (IPCC 2005). Of the range of options available, geological carbon sequestration (GCS) appears to be the most actionable and economic option for major greenhouse gas reduction in the next 10-30 years. The basis for this interest includes several factors: (1) The potential capacities are large based on initial estimates. Formal estimates for global storage potential vary substantially, but are likely to be between 800 and 3300 Gt of C (3000 and 10,000 Gt of CO{sub 2}), with significant capacity located reasonably near large point sources of the CO{sub 2}. (2) GCS can begin operations with demonstrated technology. Carbon dioxide has been separated from large point sources for nearly 100 years, and has been injected underground for over 30 years (below). (3) Testing of GCS at intermediate scale is feasible. In the US, Canada, and many industrial countries, large CO{sub 2} sources like power plants and refineries lie near prospective storage sites. These plants could be retrofit today and injection begun (while bearing in mind scientific uncertainties and unknowns). Indeed, some have, and three projects described here provide a great deal of information on the operational needs and field implementation of CCS. Part of this interest comes from several

    Nineteen carbon stars that show lithium enrichment in their atmospheres have been discovered among a sample of 674 carbon stars in the Large Magellanic Cloud. Six of the Li-rich carbon stars are of J-type, i.e. with strong 13C isotopic features. No super-Li-rich carbon stars were found. The incidence of lithium enrichment among carbon stars in the LMC is much rarer than in the Galaxy, and about five times more frequent among J-type than among N-type carbon stars. The bolometric magnitudes of ...

  9. Development of carbon-carbon composites from solvent extracted pitch

    There are several methods used to fabricate carbon-carbon composites. One used extensively in the fabrication of aerospace components such as rocket nozzles and reentry vehicle nosetips, as well as commercial components for furnace fixturing and glass manufacturing, is the densification of a woven preform with molten pitch, and the subsequent conversion of the pitch to graphite through heat treatment. Two types of pitch are used in this process; coal tar pitch and petroleum pitch. The objective of this program was to determine if a pitch produced by the direct extraction of coal could be used as a substitute for these pitches in the fabrication of carbon-carbon composites. The program involved comparing solvent extracted pitch with currently accepted pitches and rigidizing a carbon-carbon preform with solvent extracted pitch for comparison with carbon-carbon fabricated with currently available pitch.

    The two-step syntheses of the cyclic carbonates carbonated methyl oleate (CMO) and carbonated methyl linoleate (CML) are reported. First, synthesis of epoxides through well-precedented chemical reactions of unsaturated fatty methyl esters with hydrogen peroxide and formic acid was accomplished. Next, a carbonation reaction with a simple tetrabutylammonium bromide catalyst was performed, allowing the direct incorporation of carbon dioxide into the oleochemical. These syntheses avoid the use of the environmentally unfriendly phosgene. The carbonated products are characterized by IR, 1H NMR, and 13C NMR spectroscopy and studied by thermogravimetric analysis (TGA). Also reported is the synthesis of a similar cyclic carbonate from the commercially available 2-ethylhexyl epoxy soyate. These carbonates show properties that may make them useful as petrochemical replacements or as biobased industrial product precursors.

    Full Text Available Progressive cities worldwide have demonstrated political leadership by initiating meaningful strategies and actions to tackle climate change. However, the lack of knowledge concerning embodied greenhouse gas (GHG emissions of cities has hampered effective mitigation. We analyse trans-boundary GHG emission transfers between five Australian cities and their trading partners, with embodied emission flows broken down into major economic sectors. We examine intercity carbon footprint (CF networks and disclose a hierarchy of responsibility for emissions between cities and regions. Allocations of emissions to households, businesses and government and the carbon efficiency of expenditure have been analysed to inform mitigation policies. Our findings indicate that final demand in the five largest cities in Australia accounts for more than half of the nation’s CF. City households are responsible for about two thirds of the cities’ CFs; the rest can be attributed to government and business consumption and investment. The city network flows highlight that over half of emissions embodied in imports (EEI to the five cities occur overseas. However, a hierarchy of GHG emissions reveals that overseas regions also outsource emissions to Australian cities such as Perth. We finally discuss the implications of our findings on carbon neutrality, low-carbon city concepts and strategies and allocation of subnational GHG responsibility.
