    Full Text Available L’évolution des itinéraires techniques viticoles (ITKv vers un plus grand respect de l’environnement passe par une évaluation de leurs performances environnementales. Dans un contexte de gestion durable, plusieurs autres facteurs sont à prendre en compte, notamment le risque de modification de la qualité des raisins issus de ces ITKv. Les résultats d’évaluation environnementale par la méthode d’Analyse du Cycle de Vie (ACV ainsi que l’évaluation de la qualité du raisin s’appuient sur beaucoup données. Ce travail montre l’intérêt d’une méthode d’évaluation multicritère conjointe « environnement et qualité », dans le processus de changement de pratiques pour une amélioration des performances. Les résultats obtenus sur 5 ITKv montrent des différences de notes entre les 2 millésimes étudiés et des pratiques ont été identifiées pour leurs forts impacts sur les résultats ACV. Des propositions théoriques de changement de pratiques sont testées sur l’un des ITKv. Ces propositions améliorent les notes environnementales finales de +0,15 points à +0,77 points (/10 quand elles sont mises en œuvre séparément et +2,29 points (/10 en étant combinées. Un modèle explicatif de la qualité du raisin permet de vérifier que les nouvelles pratiques ne peuvent potentiellement pas altérer la qualité du raisin. La méthode d’évaluation conjointe CONTRA-QUALENVIC adaptée à la viticulture montre ici qu’elle peut être une aide à l’amélioration des ITKv.

    Full Text Available Le développement durable invite à intégrer aux modèles de raisonnement et d’action économiques la négociation entre parties intéressées et compétentes. Cette approche trouve sa traduction dans le champ économique sous la forme de la « théorie des parties prenantes », cristallisé notamment dans des outils comme la norme ISO 14001. Mais les modalités pratiques de sa mise en oeuvre ne permettent pas une intégration équilibrée des différents points de vue en présence. Le dialogue des parties prenantes qui vise à construire la « qualité environnementale » des entreprises se négocie essentiellement au sein de l’espace marchand. Le potentiel d’intégration du droit de négociation des parties prenantes paraît faible en l’absence d’un dispositif de veille citoyenne de cette qualité environnementale.Sustainable development aims to integrate stakeholder negotiation into economical reasoning and acting models. The stakeholder theory translates this approach in the economics field. Some tools like ISO 14001 standard crystallise this theory. But the practical ways of its implementation do not allow a balanced integration of the hole range of stakeholders views. Stakeholder dialog, which aims to build a consensus about enterprises “environmental quality”, is mostly negotiated inside the economic space. ISO 14001 standardisation system is not likely to allow stakeholder negotiation rights integration while citizens do not organise an environmental quality watching over network.

    Full Text Available For centuries, the local communities of yaks’ transhumant cattle farmers of the Tibetan High plateau have lived on their yak breeding activity, providing them with all they need: milk, a source of butter and cheese, and hair, which they weave into the heavy black tents that characterize the nomadic population. In the last decade, however, changes occurred that have destabilized this activity. The changes are three-fold: (1 increasing economic difficulty to live from this activity (Melvyn et al., 1990, and its two corollaries: (2 rural desertification (Yang, 1992 and (3 increasing herds’ sizes, threatening the environment (Wu, 1999. Norlha, meaning “wealth of the Gods”, proposes an alternative to remedy these problems. By improving the value added cattle that farmers derive from the yaks, Norlha’s social business model suggests that selling extremely high range products to luxury houses can be a way out of poverty and rural desertification for these communities.Pendant des siècles, les communautés locales d’éleveurs transhumants de yaks du haut plateau du Tibet ont vécu de leurs élevages qui leur fournissaient tout ce dont ils avaient besoin pour vivre : du lait, pour faire du beurre et du fromage, et de la laine, qu'ils tissaient pour fabriquer les épaisses tentes noires utilisées par les populations nomades. Toutefois, au cours des dix dernières années, l’élevage de yaks a été déstabilisé par certains  changements : (1 la difficulté de plus en plus grande à vivre de l’élevage (Melvyn et al., 1990, et ses deux corollaires, (2 la désertification rurale (Yang, 1992 et (3 des troupeaux de plus en plus importants qui menacent l’environnement (Wu, 1999. Norlha, qui signifie “richesses des Dieux”, propose une alternative à ces problèmes. En améliorant la valeur ajoutée que les éleveurs dégagent des yaks, le modèle d’entreprise social de Norlha montre que la vente de produits très haut de gamme à des

    Full Text Available La notion de gouvernance est mobilisée de manière croissante aujourd’hui pour évoquer de nouvelles formes de coopérations entre acteurs de la vie économique et sociale. Appliquée aux questions environnementales, la gouvernance pose à la fois la question de la maîtrise du temps par les acteurs et celle du territoire d’application des décisions prises. On peut donc considérer qu’elle engage un renouvellement de l’articulation entre le temps et l’espace, que doit prendre en compte l’analyse des choix économiques dans ce domaine. L’exemple du bassin d’emploi dunkerquois montre que cette articulation est au cœur d’une participation des entreprises à la gouvernance environnementale.The concept of governance is more and more raised to conjure up new ways of cooperation between actors of the economic and social life. Applied to environmental matters, governance ask both the question of mastery of the time and the one of the territory’s application for taken decisions. We can consider that it engage a renewal of the joint between time and space, that the analysis of economic choices had to take into account. The example of “Dunkerque” show that this joint is the heart of firm’s collaboration in environmental governance.

  15. Andra in Meuse/Haute-Marne

    International Nuclear Information System (INIS)

    Mazoyer, David

    2016-11-01

    Every year, France generates tens of thousands of cubic metres of radioactive waste. This waste comes from various sectors which make use of the properties of radioactivity, including nuclear power generation, defence, industry, health care and research. At present, Andra operates two waste disposal facilities in the Aube where 90% of the total volume of radioactive waste generated every year is managed. For safety reasons, the remaining 10% cannot be disposed of at these surface facilities. Some of this waste, known as high-level waste (HLW) and intermediate-level long-lived waste (ILW-LL), is highly radioactive and can remain hazardous for several hundred thousand years. A suitable solution must be implemented to manage such waste, as set down in the Act of 28 June 2006: reversible disposal in a deep geological formation. Starting with its Underground Research Laboratory in Bure (in the Meuse department), on which construction began in 2000, Andra has gradually expanded the facilities at the Meuse/Haute-Marne Centre (CMHM) in the area. In 2007, the Perennial Observatory of the Environment (OPE) was set up to better understand changes over time in the natural environment around Andra's facilities and, in 2009, the Technological Exhibition Facility opened in Saudron (in the Haute-Marne department), to present the Cigeo geological disposal facility project. Last, the Environmental Specimen Bank opened in 2014. Here, environmental monitoring samples taken in connection with the OPE are conserved for at least one hundred years. In addition to contributing to development of the two departments by creating jobs and purchasing from local suppliers, Andra has been committed to working alongside local players for the last twenty years, becoming an integral part of economic, social and cultural life in the region. If the Cigeo project is approved, the site will become a leading industrial, research and education cluster for the region. This document presents: the Andra

    Full Text Available L’article propose une analyse en termes de proximité géographique et organisée de la contribution des Démarches Environnementales Volontaires (DEV à la résolution du conflit d’usage diffus sur l’eau dans la viticulture et l’arboriculture fruitière. Dans une première partie, les DEV seront présentées comme une réponse spécifique des producteurs à ce type de conflit, la seconde partie se concentrant sur une lecture des DEV en termes de proximité. Une enquête réalisée auprès des producteurs inscrits en agriculture raisonnée ou biologique permet de montrer que la proximité organisée ne peut être porteuse à elle seule de solutions aux divergences d’intérêts entre acteurs.This paper analyses, terms of geographical and organized proximity, the contribution of Voluntary Environmental Approaches (VEA to the resolution of diffuse conflicting water uses in vine growing and fruit-bearing arboriculture. In a first part, we show that VEAs are a specific producer’s response to this kind of conflicts, the second part being centred on an analysis of VEAs in terms of proximity. An investigation towards producers engaged in integrated or organic farming shows that organized proximity alone is not able to bear solutions to divergences of interests between actors.

    1998-08-01

    High critical temperature superconductors (HTCS) are very promising for applications in microelectronics due to the control of high quality epitaxial thin films, in spite of a number of specific constraints. Active and passive devices are already available in various laboratories, prooving that applications are actually expected soon. We report here on the interest of HTCS thin films, on preparation processes including materials and substrates choice, and also on characterization methods which are required in order to chek the quality of the samples. Finally some illustrative examples of applications are presented. Les supraconducteurs à haute température critique ouvrent des perspectives prometteuses dans le domaine de l'électronique en raison de la maîtrise de la croissance de films minces de haute qualité cristalline et physique, malgré des difficultés spécifiques. Des dispositifs, aussi bien actifs que passifs, commencent à être réalisés dans divers laboratoires, montrant que des applications peuvent être effectivement envisagées à relativement court terme.

    2012-01-01

    Expanding the horizons of lesbian film, Fremde Haut is located within three broad frames: the cross-dressing genre, the New Queer Cinema (NQC) movement, and an Accented or diasporic film aesthetic. While strong connections exist between the cross-dressing film and NQC, less addressed are the links between the New Queer and the Accented yet these are of more radical, that is queerer, potential. Through Fremde Haut, this article illustrates how intimately tied to race and nation, gender and sexuality are, to reveal the accented as queer and the queer as accented. Ultimately, what is distinguished is the potency of a new "quare" cinema.

    Full Text Available Le développement du trekking au Népal a suscité des inquiétudes qui ont abouti à la création d’aires protégées sur la foi d’un scénario de crise environnementale dont les touristes et les paysans étaient jugés responsables. Devant les conflits entre la conservation et les nécessités de développement des régions concernées, la gouvernance des aires protégées a évolué dans le sens d’une meilleure prise en compte des sociétés locales. Pour autant les mesures prises ne font qu’accompagner et diriger des dynamiques touristiques plus anciennes qui s’exercent à des échelles plus vastes. Le trekking constitue ainsi un système touristique très largement aux mains des sociétés montagnardes du pays qui a permis l’amélioration de leurs conditions de vie tout en limitant ses impacts environnementaux. En ce sens le trekking répond assez largement aux principes du développement durable.Against a backdrop of environmental crisis, attributed to the impact of tourism and the practices of rural populations, Nepal has created protected areas with a view to preserving the Himalayan environment and promoting sustainable tourism in the regions concerned. Given the conflicts between conservation needs and development needs, local communities are now being given a bigger role in the governance of these protected areas. Yet the measures being taken simply accompany and guide well-established tourism dynamics that operate on a much greater scale. Trekking is thus a tourism system largely in the hands of the country’s mountain communities and is an activity that has enabled these communities to improve their living conditions while at the same time limiting environmental impacts. In this sense it is very much in line with the principles of sustainable development.

Ces aspects sont inégalement présents dans les différents sous-secteurs de l’industrie des corps gras ; quelques exemples sont présentés. La réduction des émissions de COV (composés organiques volatils et les nuisances olfactives sont une problématique concernant principalement l’activité de trituration, la lipochimie et la fonte de corps gras animaux. Des valeurs limites de consommation de solvant sont maintenant imposées réglementairement en extraction; la prise en compte de problèmes de nuisance olfactive donnent lieu à l’amélioration des procédés de traitement d’air (corps gras animaux ou à leur mise en place progressive (trituration de colza. La gestion des déchets reste une préoccupation essentielle pour l’ensemble de la profession et tout particulièrement pour les secteurs des corps gras animaux et la lipochimie, en raison de la remise en cause des filières d’élimination due au renforcement des contraintes réglementaires, mais aussi en raison des coûts de traitement. Ce poste ne doit pas être négligé par les entreprises : réduction à la source, recherche de filières pérennes, valorisation énergétique ou matière sont des éléments permettant également une réduction significative des coûts. La maîtrise de la consommation d’énergie est un élément important, voir stratégique, notamment dans le secteur de la trituration des graines oléagineuses. Des actions de sensibilisation permettent de poursuivre également l’effort auprès des PME, actuellement moins impliquées. En matière de traitement d’eau, des avancées notables sont observées depuis une décennie ; néanmoins certaines difficultés persistent, notamment dans les

    Une caracterisation des emissions atmospheriques provenant des sources fixes en operation, alimentees au gaz et a l'huile legere, a ete conduite aux installations visees des sites no.1 et no.2. La caracterisation et les calculs theoriques des emissions atmospheriques aux installations des sites no.1 et no.2 presentent des resultats qui sont en dessous des valeurs reglementaires pour des conditions d'operation normales en periode hivernale et par consequent, a de plus fortes demandes energetiques. Ainsi, pour une demande energetique plus basse, le taux de contaminants dans les emissions atmospheriques pourrait egalement etre en dessous des reglementations municipales et provinciales en vigueur. Dans la perspective d'une nouvelle reglementation provinciale, dont les termes sont discutes depuis 2005, il serait souhaitable que le proprietaire des infrastructures visees participe aux echanges avec le Ministere du Developpement Durable, de l'Environnement et des Parcs (MDDEP) du Quebec. En effet, meme si le principe de droit acquis permettrait d'eviter d'etre assujetti a la nouvelle reglementation, l'application de ce type de principe ne s'inscrit pas dans ceux d'un developpement durable. L'âge avance des installations etudiees implique la planification d'un entretien rigoureux afin d'assurer les conditions optimales de combustion en fonction du type de combustible. Des tests de combustion sur une base reguliere sont donc recommandes. Afin de supporter le processus de suivi et d'evaluation de la performance environnementale des sources fixes, un outil d'aide a la gestion de l'information environnementale a ete developpe. Dans ce contexte, la poursuite du developpement d'un outil d'aide a la gestion de l'information environnementale faciliterait non seulement le travail des personnes affectees aux inventaires annuels mais egalement le processus de communication entre les differents acteurs concernes tant intra- qu'inter-etablissement.

    This report aims to analyze the geothermal potential of the Meuse/Haute-Marne site selected for the Cigeo project, primarily based on data available in the literature and particularly on those recently Acquired by Andra near this site. It also analyzes the report made on the same topic by Geowatt AG at The request of the CLIS of Bure. For the Meuse/Haute-Marne area relevant to Cigeo, the present report concludes to the existence of A low-energy geothermal resource in the lower Triassic. For the Permian and the basement, a medium To high-energy geothermal resource is conceivable, but its occurrence is hypothetical. Beneath the site, exploiting the Triassic would depend on the possibility of re-injecting the produced Brine. National and international experiences show the difficulty to carry out such a reinjection in Silty-clayey formations. The profitability of such exploitation in the Triassic, the Permian or in the basement is questionable. Indeed, the Meuse/Haute-Marne area neither shows an exceptional nature nor a specific interest Compared to other formations or zones for which either the geothermal potential is better Demonstrated, such as for instance the Dogger formation in the central part of the Paris basin with Easier exploitation conditions, or where the geothermal gradients are higher.

    France had established in advance of last year's climate summit in Paris on ambitious energy policy goals. Especially the 2016 newly formed Region Hauts-de-France stands out as a pioneer here. There one drives innovation and investments with the objective of fulfilling by 2050 their own needs completely by renewable sources. The orientation to supplies Jeremy Rifkin idea of the third industrial revolution. If successful, the region would be on climate protection well ahead of the national targets, the 2050 ''only'' provide a CO{sub 2} emission reduction of 75%. In addition to the Research and development (R and D) to many future ideas in Hauts-de-France but also some major projects for Security of European energy supplies are realized that show the local agility. [German] Frankreich hatte sich im Vorfeld des letztjaehrigen Pariser-Klimagipfels auf ambitionierte Energiewendeziele festgelegt. Insbesondere die 2016 neu gebildete Region Hauts-de-France sticht dabei als Vorreiter heraus. Dort treibt man Innovationen und Investitionen mit dem Ziel an, bis 2050 den Eigenbedarf vollstaendig mittels erneuerbarer Quellen zu decken. Die Orientierung dazu liefert Jeremy Rifkins Idee der dritten industriellen Revolution. Im Erfolgsfall laege die Region beim Klimaschutz deutlich vor den nationalen Zielen, die bis 2050 ''nur'' eine CO{sub 2}-Emissionsreduktion von 75 % vorsehen. Neben der Forschung und Entwicklung (F and E) zu vielen Zukunftsideen werden in Hauts-de-France aber auch einige Grossprojekte zur Absicherung der europaeischen Energieversorgung realisiert, die Ausweis der dortigen Agilitaet sind.

  2. Ifp's New Flexible Hydrocracking Process Combines Maximum Conversion with Production of High Viscosity, High Vi Lube Stocks Le nouveau procédé IFP d'hydrocraquage à haute flexibilité combine conversion maximum et production de bases, huile à haute viscosité et à indice de viscosité élevé

    Full Text Available Institut Français du Pétrole (IFP has developed a new dual catalytic system for its hydrocracking process that enables high conversion to middle distillates and production of high viscosity, high VI lube stocks. Although the hydrocracking process is mainly devoted to the conversion of vacuum distillates, deasphalted oil or mixture of both into high quality middle distillates, it can also produce a residue, that after dewaxing will be a very high VI lube base oil. In this presentation major emphasis is put on the possibility to produce very high VI lubes with high viscosity thanks to the development of the new catalytic system. Large flexibility in feedstock selection and easy control of operating variables allow the production of all grades of lube oils associated with high quality middle distillates for a large range of conversion levels. L'Institut Français du Pétrole (IFP a mis au point, pour son procédé d'hydrocraquage, un nouveau système catalytique à 2 catalyseurs qui permet une forte conversion en distillats moyens et la production de fractions lubrifiantes à haute viscosité et indice de viscosité élevé. Si le procédé d'hydrocraquage est essentiellement utilisé pour la conversion de distillats sous vide, d'huile désasphaltée ou d'un mélange des deux en distillats moyens de haute qualité, il peut aussi produire un résidu qui, après déparaffinage, fournira une base pour lubrifiant à indice de viscosité très élevé. Cet article souligne particulièrement la possibilité de produire des lubrifiants à indice de viscosité très élevé et haute viscosité, grâce à ce nouveau système catalytique. Une grande flexibilité dans le choix des produits à traiter et la facilité de contrôle des paramètres opératoires permet la production de toutes les qualités d'huiles lubrifiantes associées à des distillats moyens de haute qualité, pour une large gamme de niveaux de conversion.

    Primär kutane B-Zell-Lymphome (PCBCL) beschreiben reifzellige lymphoproliferative Erkrankungen der B-Zell-Reihe, die primär die Haut betreffen. Die Biologie und der klinische Verlauf der einzelnen PCBCL-Subtypen variieren untereinander stark und unterscheiden sich grundsätzlich von primär nodalen und systemischen B-Zell-Lymphomen. Primär kutane Marginalzonenlymphome (PCMZL) und primäre kutane follikuläre Keimzentrumslymphome (PCFCL) werden auf Grund ihres unkomplizierten Verlaufs und ihrer exzellenten Prognose zu den indolenten PCBCL gezählt. Demgegenüber stellen die diffus großzelligen B-Zell-Lymphome, hauptsächlich vom Beintyp (DLBCL, LT) die aggressiveren PCBCL-Varianten mit schlechterer Prognose dar. Für die Ausbreitungsdiagnostik und die Therapieentscheidung sind eine genaue histologische und immunhistochemische Klassifizierung sowie der Ausschluss einer systemischen Beteiligung in Abgrenzung zu nodalen oder systemischen Lymphomen notwendig. Die Diagnostik sollte dabei durch molekularbiologische Untersuchungen unterstützt werden. Therapeutisch stehen für die indolenten PCBCL primär operative und radioonkologische Maßnahmen im Vordergrund sowie eine Systemtherapie mit dem CD20-Antikörper Rituximab bei disseminiertem Befall. Die aggressiveren Varianten sollten in erster Linie mit Kombinationen aus Rituximab und Polychemotherapieschemata wie z. B. dem CHOP-Schema oder Modifikationen davon behandelt werden. Auf Grund der in allen seinen Einzelheiten noch nicht vollständig verstandenen Pathogenese und Biologie sowie des begrenzten Therapiespektrums der PCBCL besteht hier, speziell beim DLBCL, LT, noch erheblicher Forschungsbedarf. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

  17. Les reseaux de politique publique comme facteur d'influence du choix des instruments de politique energetique canadienne a des fins environnementales de 1993 a nos jours

    Fathy El Dessouky, Naglaa

    Au cours de la derniere decennie, les modes de la gouvernance ont pris place dans un contexte totalement different de celui qu'ils avaient auparavant. Les gouvernements modernes se rendent compte qu'ils perdent de plus en plus leur capacite a elaborer et a gerer les changements d'une maniere autonome. Ainsi, les fonctions et les activites traditionnellement accomplies exclusivement par le gouvernement engagent de nos jours une gamme d'acteurs etatiques et non etatiques. A l'encontre du concept traditionnel de l'Etat controleur, la gouvernance contemporaine est ainsi devenue moins une question d'offre de service et davantage une gestion indirecte des reseaux de politique publique. Dans cette entreprise, les gouvernements contemporains, cherchant plus d'information, de soutien et de legitimite en matiere de formulation des decisions, ont besoin d'etablir des relations avec les divers groupes d'interet qui, a leur tour, voulaient plus de promotion et de protection en faveur de leurs interets a travers leur implication au processus de l'elaboration et de la mise en oeuvre des politiques publiques. Ainsi, l'approche des reseaux de politique publique represente aujourd'hui un courant considerable au sein du champ d'analyse des politiques publiques. Toutefois, les preoccupations des chercheurs pour cette approche, dans le domaine des politiques energetiques a des fins environnementales, semblent recentes, et les etudes realisees sont encore trop peu nombreuses. Au Canada, au debut des annees 1990, le gouvernement ainsi que plusieurs groupes d'interets, des differents secteurs energetique, industriel et environnemental, ont commence a intensifier leurs efforts pour s'attaquer au probleme du changement climatique d'origine energetique, genere surtout par le secteur de l'industrie. Au cours de la derniere decennie, la question touchant plutot le sujet du developpement energetique durable represente le plus important domaine des politiques publiques ayant surgi recemment dans

    Escoffier, S

    2002-04-01

    Within the framework of a feasibility study of underground radioactive waste repository the experimental characterization of the coupled behavior of the host layer is of first importance. This work concerns the experimental characterization in laboratory of the poro-elastic behavior of argillite which constitutes the host layer of the future underground laboratory of ANDRA located at the limit of the Meuse/Haute-Marne. The theoretical approach is the Mechanics of Porous Media defined by Coussy [1991] which has the advantage of providing a formulation of the behavior laws using measurable parameters in laboratory. The difficulties or the feasibility of the characterization tests of these rocks coupled behavior are related to their very low permeability which requires an adaptation of the experimental devices initially used on more permeable rocks. Initially a synthesis on the knowledge of the poro-elastic parameters of Meuse/Haute-Marne argillite is given. Thereafter a first approach of the use of the studies of sensitivity as tools of decision-making aid is proposed. The experimental difficulties encountered by the various experimenters are illustrated by the diversity of the experimental choices, the test duration or by the results disparity. Because of economic, political and ecological stake, the studies of sensitivity could make it possible to direct the experimental efforts by giving indications on the dominating parameters in the coupled behavior of a rock. In the second time after the presentation of the test results of physical characterization 3 types of tests are described: permeability test (pulse test), determination of Biot coefficient under odometric loading and isotropic drained test. The complexity of these tests is related to the attack of the experimental limits. They are presented in detail: theoretical recalls, experimental set up, experimental protocol, unfolding and test results. (author)

Avec l’aide des partenaires étrangers le pays étend actuellement de manière spectaculaire son réseau d’espaces protégés.

Dans bien des cas, lorsque la gestion des milieux sensible est retirée aux communautés locales au profit d’acteurs institutionnels, on assiste au développement de ces activités destructrices. Pour lutter contre cet effet pervers de l’institutionnalisation de la protection environnementale, il devient urgent de disposer d’un plus large panel de systèmes de gouvernance.

    Digital flood-inundation maps for a 6.3-mi reach of the Wabash River from 0.1 mi downstream of the Interstate 70 bridge to 1.1 miles upstream of the Route 63 bridge, Terre Haute, Indiana, were created by the U.S. Geological Survey (USGS) in cooperation with the Indiana Department of Transportation. The inundation maps, which can be accessed through the USGS Flood Inundation Mapping Science Web site at http://water.usgs.gov/osw/flood_inundation/, depict estimates of the areal extent of flooding corresponding to select water levels (stages) at the USGS streamgage Wabash River at Terre Haute (station number 03341500). Current conditions at the USGS streamgage may be obtained on the Internet from the USGS National Water Information System (http://waterdata.usgs.gov/in/nwis/uv/?site_no=03341500&agency_cd=USGS&p"). In addition, the same data are provided to the National Weather Service (NWS) for incorporation into their Advanced Hydrologic Prediction Service (AHPS) flood warning system (http://water.weather.gov/ahps//). Within this system, the NWS forecasts flood hydrographs for the Wabash River at Terre Haute that may be used in conjunction with the maps developed in this study to show predicted areas of flood inundation. In this study, flood profiles were computed for the stream reach by means of a one-dimensional step-backwater model. The model was calibrated using the most current stage-discharge relation at the Wabash River at the Terre Haute streamgage. The hydraulic model was then used to compute 22 water-surface profiles for flood stages at 1-ft interval referenced to the streamgage datum and ranging from bank-full to approximately the highest recorded water level at the streamgage. The simulated water-surface profiles were then combined with a geographic information system digital elevation model (derived from Light Detection and Ranging (LiDAR) data having a 0.37-ft vertical accuracy and a 1.02-ft horizontal accuracy) to delineate the area flooded at each water

    Full Text Available Background: In Burkina Faso, phytotherapy is the main medical alternative used by populations to manage various diseases that affect the nervous system. The aim of the present study was to report medicinal plants with psychoactive properties used to treat neuropsychiatric disorders in the Hauts Bassins region, in the western zone of Burkina Faso. Methods: Through an ethnobotanical survey using structured questionnaire, 53 traditional healers (TH were interviewed about neuropsychiatric disorders, medicinal plants and medical practices used to treat them. The survey was carried out over a period of three months. Results: The results report 66 plant species used to treat neuropsychiatric pathologies. Roots (36.2% and leaves (29% were the main plant parts used. Alone or associated, these parts were used to prepare drugs using mainly the decoction and the trituration methods. Remedies were administered via drink, fumigation and external applications. Conclusions: It appears from this study a real knowledge of neuropsychiatric disorders in the traditional medicine of Hauts Bassins area. The therapeutic remedies suggested in this work are a real interest in the fight against psychiatric and neurological diseases. In the future, identified plants could be used for searching antipsychotic or neuroprotective compounds.

    The Aouli Pluton consists of four units: (1) granodiorite; (2) grey granite; (3) pink granite - these three units constituting a spatially continuous massif, and (4) muscovite granite, which is exposed in two small stocks somewhat removed from the other units. U-Pb ages obtained on zircon and titanite are 333 ± 2 Ma and 319 ± 1.5 Ma for the granodiorite and grey granite respectively. The 14 ma age difference between the granodiorite and the grey granite supports the multiple injection hypothesis which was the outcome of geochemical studies (Oukemeni and Bourne, 1993). These two rocks also contain an inherited component which has been dated at 1520 Ma in the granudiorite and at 1245 ma and 1804 Ma in the grey granite. The inherited components suggest the possible presence of Precambian crust below the Haute Moulouya. Since the intrusion is late-to post-tectonic (Oukemeni and Bourne, 1993), the age of the granodiorite (333 ± 2 Ma) indicates that the Hercynian deformation is pre-Visean in the Haute Moulouya area, and, by extension, throughout the eastern meseta region.

    Summary Les brûlures électriques par haut voltage sont responsables de gros dégâts tissulaires en immédiat et dans les jours suivant l’accident du fait de la chaleur importante dégagée par effet joule et de la thrombose microvasculaire évolutive. Les pertes de substances du scalp secondaires à ces brûlures nécessitent une couverture par lambeaux vu la destruction du périoste et du calvarium en regard. De juin 1997 à juin 2008, 15 patients ont été traités pour des pertes de substance du scalp secondaires à des brûlures électriques par haut voltage de diamètre allant de 8 à 11 cm et siégeant dans la région tonsurale. Ces patients ont été opérés dans la première semaine suivant l’accident. Les pertes de substance du scalp de taille moyenne secondaires à ces brûlures peuvent être couvertes per primam de façon fiable par des lambeaux locaux axialisés et multiples. Nous relatons l’expérience du Service de Chirurgie Plastique du Centre Hospitalier Universitaire Ibn-Sina, Rabat, Maroc, dans la gestion et la prise en charge de ces brûlures. PMID:22262963

    A first report proposes an analysis of the situation of methanization installations in the Haute-Normandie region while recalling the national context. It briefly reports an analysis and assessment of waste flows, processed effluents, by-products and biomass displaying an energetic potential. It describes methanization installations by addressing the different steps of the methanization process, by presenting the different digestion indicators, by briefly evoking the issue of the return-to-soil of digestates, and by presenting various operational data. Financial aspects are then addressed (investments and subsidies, financial balance of farm-based and collective installations), and an overview of methanization projects in the region and development perspectives is proposed. The second report more precisely analyses development perspectives for the methanization sector in the region through a brief assessment of the methanizable organic substrate resource, a discussion of different associated challenges (energy, agronomic, environmental and societal), a discussion of development levers and brakes, and an analysis of competitions (related to the use of industrial by-products, between processing installations, and related to agricultural soils). Another document proposes an overview of various aspects of methanization: a tool for territorial development, regulatory framework, evolution of installations in the region, assets of methanization, and role of the regional commission of expertise on methanization

  8. Study of current instabilities in high resistivity gallium arsenide; Etude des instabilites de courant dans l'arseniure de gallium de haute resistivite

    We have shown the existence and made a study of the current oscillations produced in high-resistivity gallium arsenide by a strong electric field. The oscillations are associated with the slow travelling of a region of high electrical field across the whole sample. An experimental study of the properties of these instabilities has made it possible for us to distinguish this phenomenon from the Gunn effect, from acoustic-electric effects and from contact effects. In order to account for this type of instability, a differential trapping mechanism involving repulsive impurities is proposed; this mechanism can reduce the concentration of charge carriers in the conduction band at strong electrical fields and can lead to the production of a high-field domain. By developing this model qualitatively we have been able to account for all the properties of high-resistance gallium arsenide crystals subjected to a strong electrical field: increase of the Hall constant, existence of a voltage threshold for these oscillations, production of domains of high field, low rate of propagation of these domains, and finally the possibility of inverting the direction of the propagation of the domain without destroying the latter. A quantitative development of the model makes it possible to calculate the various characteristic parameters of these instabilities. Comparison with experiment shows that there is a good agreement, the small deviations coming especially from the lack of knowledge concerning transport properties in gallium arsenide subjected to high fields. From a study of this model, it appears that the instability phenomenon can occur over a wide range of repulsive centre concentrations, and also for a large range of resistivities. This is the reason why it appears systematically in gallium arsenide of medium and high resistivity.

  10. La territorialisation des politiques environnementales

    Directory of Open Access Journals (Sweden)

    Amédée Mollard

    2010-10-01

    Full Text Available Le point de départ de cet article est la grande variabilité de la pollution nitrique diffuse de l’eau due à l’agriculture. Celle-ci dépend en particulier du climat, des types de sol et des systèmes de production agricole. Nos recherches réalisées de façon interdisciplinaire à partir de deux sites différents en France, montrent que cette hétérogénéité spatio-temporelle conditionne les pratiques agricoles mises en œuvre pour réduire la pollution au niveau de la norme admise. De ce fait, les pratiques les plus « coût-efficaces » diffèrent d’un territoire à l’autre, en fonction des caractéristiques locales. Ces résultats mettent donc en évidence une efficacité potentielle d’une territorialisation des politiques publiques. En théorie, de telles politiques sont considérées comme optimales par les économistes, car elles incitent les agents à moduler leurs efforts en fonction de la sensibilité du milieu. Mais, selon les études empiriques, cet avantage serait annulé par un coût élevé de mise en œuvre, de contrôle et de surveillance. Pour maintenir leur avantage sur des politiques uniformes, les politiques territorialisées devraient être mises en œuvre à un niveau spatial optimal. Un tel niveau devrait au minimum atteindre un compromis entre l’économie réalisée grâce à une modulation adaptée aux conditions locales et les sur-coûts dus à la décentralisation des solutions mises en œuvre. Cet article analyse la pertinence d’une prise en compte de ces spécificités par des politiques territorialisées. L’efficacité d’une régulation différenciée de la pollution nitrique est étudiée ici en évaluant l’importance de la variabilité spatiale des paramètres physiques et des coûts de la territorialisation.The paper starts with the wide variability of nonpoint water nitrogenous pollution generated by agriculture. This variability depends especially on climate, soil types and farming systems. Our interdisciplinary researches, carried out on two different sites in France, show that space and time heterogeneity influence farm practices to be implemented in order to reduce pollution at the standard level. Hence the most cost-effective farm practices are different from one place to another, depending on local characteristics. Therefore this result emphasises the potential efficiency of spatially targeted policies. Theoretically, such policies are considered optimal, since economic agents tune their efforts according to the sensitivity of the milieu where they operate. But, according to empirical analyses, this advantage is counteracted by a high cost of implementation, monitoring and enforcement. In order to maintain the advantage of site-specific policies versusuniform policies, the former have to be implemented at an optimal level of space. This level should at least allow for a trade-off between lower expenses due to an appropriate tuning to the local conditions and heavier costs of decentralised measures. This paper deals with this specific question regarding territorialized policies. It is based on a study of the efficiency of differentiating the way this pollution is regulated, focussed on assessing the importance of spatial variability in physical parameters and in site-specific policies’ costs.

    This study follows a study realised in the late 80's by the National cancer institute to analyse the rate of cancers near american nuclear power plants (Jablon S and al, Jama 1991). The rates of mortality for the leukemia of child remain near 1 but increased in the proximity of nuclear power plants still in operation, in a statistically significant way only for old ones; they decreased in the proximity of nuclear power plants that are no more in operation. However, we must be cautious with the interpretation of these results. the question arises of an influence of environmental radioisotopes but other factors can occur ( social situation, other atmospheric pollutants, proximity of medical centers). Otherwise, the incidence of the child leukemia has very much increased these last years without any clear explanation ( =28% in Usa between 1975 and 2004). On the other hand, the rate of mortality decreased because of more efficient treatments (-49% on the same period). These findings justify to continue studies on leukemia of child in the vicinity of nuclear power plants, studies of incidences got from registers susceptible to give the most interesting results.

  13. Experimental characterization of the hydro-mechanical behaviour of Meuse/Haute-Marne argilites

    Escoffier, S.

    2002-04-01

    Within the framework of a feasibility study of underground radioactive waste repository the experimental characterization of the coupled behavior of the host layer is of first importance. This work concerns the experimental characterization in laboratory of the poro-elastic behavior of argillite which constitutes the host layer of the future underground laboratory of ANDRA located at the limit of the Meuse/Haute-Marne. The theoretical approach is the Mechanics of Porous Media defined by Coussy [1991] which has the advantage of providing a formulation of the behavior laws using measurable parameters in laboratory. The difficulties or the feasibility of the characterization tests of these rocks coupled behavior are related to their very low permeability which requires an adaptation of the experimental devices initially used on more permeable rocks. Initially a synthesis on the knowledge of the poro-elastic parameters of Meuse/Haute-Marne argillite is given. Thereafter a first approach of the use of the studies of sensitivity as tools of decision-making aid is proposed. The experimental difficulties encountered by the various experimenters are illustrated by the diversity of the experimental choices, the test duration or by the results disparity. Because of economic, political and ecological stake, the studies of sensitivity could make it possible to direct the experimental efforts by giving indications on the dominating parameters in the coupled behavior of a rock. In the second time after the presentation of the test results of physical characterization 3 types of tests are described: permeability test (pulse test), determination of Biot coefficient under odometric loading and isotropic drained test. The complexity of these tests is related to the attack of the experimental limits. They are presented in detail: theoretical recalls, experimental set up, experimental protocol, unfolding and test results. (author)

    The subject of this Ph.D. thesis deals with research achieved in the context of the Axis 2 of the law Bataille voted on December 30, 1991 about the possibility of building a deep geological repository for medium or high activity and long living nuclear waste. Nearby such a site, some microorganisms may influence the mobility of radionuclides coming from the waste canisters. This work consisted in looking for autochthonous microorganisms in the Opalinus clay formation from Mont Terri (Switzerland) and in the Callovo-Oxfordian argillite from Meuse/Haute-Marne (France). Microbial Investigations in these unknown unperturbed environments suggested very low microbial densities in the clayey sediments. However, new bacterial species could be isolated from those samples. In addition, a part of the allochthonous population, which has been introduced by air and human activity, could be identified in the Meuse/Haute-Marne underground research laboratory. (author)

    Das Rhizom von Potentilla officinalis (PO) ist reich an Gerbstoffen und wird traditionell zur äußerlichen Behandlung von Entzündungen der Haut und der Schleimhäute verwendet. Ziel der vorliegenden Arbeit war die Bestätigung der antiinflammatorischen Eigenschaften von PO mittels eines UV-Erythem-Tests und einer klinischen Anwendungsstudie bei atopischer Haut. Die antiinflammatorische Wirkung eines PO-Extrakts (standardisiert auf 2 % Trockensubstanz) wurde in einer prospektiven, randomisierten, placebokontrollierten Doppelblindstudie mit 40 gesunden Erwachsenen im UV-Erythem-Test im Vergleich zu 1 % Hydrocortisonacetat untersucht. Im Rahmen einer prospektiven nicht kontrollierten Studie wurde die Wirkung und Verträglichkeit der 2 % PO-Creme an zwölf Erwachsenen und zwölf Kindern mit atopischer Haut nach Anwendung über zwei Wochen in einem definierten Testareal anhand eines Teil-SCORAD untersucht. Zusätzlich wurde die Beeinflussung der Hautrötung im Testareal photometrisch gemessen. Im UV-Erythem-Test zeigte die PO-Creme eine signifikante Reduktion des Erythemindex im Vergleich zum Vehikel. Die antiinflammatorische Wirkung des Verums entsprach der der 1 % Hydrocortisonacetat-Creme. Die klinische Studie bei Atopikern zeigte eine signifikante Abnahme des Teil-SCORAD und des Erythems im Testareal. Es wurden keine Unverträglichkeitsreaktionen beobachtet. PO als 2%ige Zubereitung besitzt entzündungshemmende Eigenschaften und ist wirksam und gut verträglich auf atopischer Haut. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

La guerre du Golfe de 1990-1991, avec l’utilisation des armes à l’uranium appauvri et l’incendie des puits de pétrole a fait de la protection de l’environnement lors des conflits armés une préoccupation internationale.

    Roozendael, M. Van; de Mazière, M.; Fayt, C.; Hendrick, F.; Hermans, C.

    Since December 2000, a ground-based off-axis DOAS spectrometer has been operated by BIRA-IASB in the South of France at the Observatoire de Haute Provence (OHP, 44°N). The design of the instrument allows automated observations of the scattered light alternatively in the zenith direction and at 10° above the horizon (off-axis geometry). The spectrometer is polarised and follows the azimuth of the sun. Its temperature is regulated and it is equipped with a Princeton Instruments/ Hammamatsu cooled diode array detector. Observations are made every 5 minutes in the 320-390 nm range. The analysis of the spectra recorded between January and December 2001 demonstrates the sensitivity of the measurements to tropospheric contents of NO2, HCHO, O3 and BrO. Results show a large seasonality in the HCHO content with maximum values in summer. The tropospheric BrO column is found to be stable over the year in the range of approximately 1.5-2 x1013 molec/cm2, roughly consistent with GOME observations at Northern mid-latitudes. Large increases of the BrO concentration are observed in summer likely due to local pollution in the vicinity of the station.

    A heating experiment named TER is being conducted with the objectives to identify the thermal properties, as well as to enhance the knowledge on THM processes in the Callovo-Oxfordian clay at the Meuse/Haute Marne Underground Research Laboratory (France). The in situ experiment has being switched on from early 2006. The heater, 3 m length, is designed to inject the power in the undisturbed zone at 6 m from the gallery wall. A heater packer is inflated in a metallic tubing. During the experiment, numerous sensors are emplaced in the surrounding rock and are experienced to monitor the evolution in temperature, pore-water pressure and deformation. The models and numerical codes applied should be validated by comparing the modeling results with the measurements. In parallel, some lab testing have been achieved in order to compare the results given with two different scales (cm up to meter scale). In this paper, we present a general description of the TER experiment with installation of the heater equipment and the surrounding instrumentation. Details of the in situ measurements of temperature, pore-pressure and strain evolutions are given for the several heating and cooling phases. The thermal conductivity and some predominant parameters in THM processes (as linear thermal expansion coefficient and permeability) will be discussed. (authors)

    In R.F. discharges at reduced pressure a resonance can increase by an order of magnitude the intensity of the plasma R.F. electric field. The electron density of the plasma adjusts itself to keep the resonant frequency equal to the excitation frequency. This behaviour has been observed by an electron beam technique. When such a discharge is excited in electronegative gases, the negative ion density may be higher than the electron density.

  3. A study on the dynamic behavior of the Meuse/Haute-Marne argillite

    Cai, M.; Kaiser, P. K.; Suorineni, F.; Su, K.

    Excavation of underground tunnels can be conducted by tunnel boring machines (TBM) or drill-and-blast. TBMs cause minimum damage to excavation walls. Blasting effects on excavation walls depend on the care with which the blasting is executed. For blast-induced damage in excavation walls, two issues have to be addressed: rate of loss of confinement (rate of excavation) and dynamic loading from wave propagation that causes both intended and unintended damage. To address these two aspects, laboratory dynamic tests were conducted for the determination of the dynamic properties of the Meuse/Haute-Marne argillite. In the present study, 17 tensile (Brazilian) and 15 compression split Hopkinson pressure bar (SHPB) tests were conducted. The test revealed that the dynamic strengths of the argillite are strain rate dependent. The average dynamic increase factors (ratio of dynamic strength to static strength) for tensile and compressive strength are about 3.3 and 2.4, respectively. A high-speed video camera was used to visualize the initiation of failure and subsequent deformation of the specimens. The direct compression specimens were found to deform and fail uniformly around the circumference of the specimen, by a spalling process. The SHPB Brazilian tests indicated that failure occurred in tension along the line of load application. Radial fractures were also observed. The test results can be used for the development of a dynamic constitutive model for the argillite for the prediction of damage in underground excavation utilizing the drill-and blast method.

    L'opacification du cristallin après irradiation par des neutrons et d'autres rayonnements ionisants a été largement étudiée, vu l'importance de telles recherches en radioprotection et la possibilité offerte par ce système d'analyser les effets produits par de petites doses de rayonnement. Les neutrons de haute énergie sont d'un intéret particulier pour la radioprotection près des accélérateurs et dans l'espace, mais jusqu'à présent les études ont été limitées aux neutrons d'énergie inférieur à 14 MeV. L'opacification du cristallin chez la souris, après irradiation par des neutrons de 400 MeV produits par le Synchro-Cyclotron du CERN, a été étudiée. Le valeurs d'E.B.R. ont été déterminées par comparaison avec des rayons X de 250 kV. Une breve discussion des résultats obtenus est inclue dans la présentation.

More than 35 wells ranging from 400 to 700 meters deep were drilled over 15 years to study a 400 km 2 area around the Andra's Meuse / Haute-Marne Underground Research Laboratory (URL). An original methodology was applied in these wells to characterize the geology, the hydrogeology and the geochemistry of the Jurassic carbonates. This multidisciplinary effort provided a unique set of 3D data. The first purpose of this study is to integrate the geological, hydrogeological and geochemical data into a water flow conceptual model. Geological data include the study of cored wells, complete modern wire-line log sets in both cored and un-cored wells, and outcrop analogues. Hydrogeological data include transmissivity and hydraulic head measurements in the Oxfordian and Dogger limestone formations. Geochemical data include several on site measurements (pH, alkalinity, electrical conductivity, temperature) and chemical and isotopic analyses performed on water samples taken at selected depths. More than one hundred hydraulic tests have been performed since 1994 to measure transmissivity distribution in the Oxfordian and Dogger limestone. Several hydraulic testing methods were used in each well: global pumping tests, fluid logging tests, thermal flow logging tests and packer tests. After completion of the hydraulic tests, hydraulic heads were deduced from long term pressure measurements in open wells or in multi-packer completions; pressure monitoring lasted between a few months and more than 10 years. Long term/high volume pumping tests were also performed after the hydraulic tests to obtain a stationary composition of the well

  6. Artificial snowmaking and potential water conflicts in mountain resorts. The case of Avoriaz (Haute-Savoie, France)

    The practice of artificial snowmaking is recent (1990s), and may use large volumes of water. In the French Alps, the total consumption is on average 20 Mm3 per year (Miquel, 2003), which corresponds to the annual consumption of drinking water for a city of more than 300,000 inhabitants such as Nice (France). Moreover, snowmaking does not represent the only use of water in winter sport resorts. The available water resource is used for drinking water, artificial snowmaking and leisure activities (swimming pools, golf spas). One can speak in this context of a multifunctionality of the resource. Of particular concern is the winter season when streams reach their lowest level (from December to April). These activities require that water is drawn from resources created at other times of the year. Water for snowmaking production is pumped from drinking water reservoirs, rivers, groundwater tables, artificial hydropower reservoirs, as well as from hill water reservoirs, specifically built for storing water for snow production, themselves supplied from surface water capture. In Avoriaz (Haute-Savoie, France) the risk of shortages is important. The reason is that the resort is supplied by a unique lake or hillside reservoir (Lake 1730), which satisfies two particularly high-consuming water uses (the water supply for production of snow and drinking water). On a finer scale, namely that of a single day in January 2011, considerable volumes are drawn off in the space of a few hours (10,114 m3 on 24 January), while pumping for drinking water spreads out over several months. Intensity of use for the production of snow can trigger water scarcity and water conflicts with other uses such as drinking water. Good management of the resource is, therefore, especially important. However, no legislation specific to artificial snowmaking has been established. Even if, at present, there is no situation involving shortages and conflicting uses at Avoriaz, the situation needs to be monitored

    Full Text Available In the central High Atlas of Morocco, the Liassic series present different mud-moundtype carbonate buildups, well developed in the Midelt area, towards the boundary between the Lower and the Upper Sinemurian. Near Foum Tillicht, these structures show a real evolution within the Upper Sinemunan interval, from simple small-scale bodies at the base, up to big and complex forms at the top. Their sedimentological and palaeontological features indicate microbolites and sponge buildings developed in deep and open marine conditions, within the subphotic zone, at the lower part of the storm wave interval. These buildups are closely linked to tectonic processes as they grow on the normal synsedimentary faults which affected the central atlasic area during the Lower Liassic period, leading to the breakup of the Early Sinemurian carbonate platform and the induced installation of the Upper Sinemurian subsiding basin. Silting by hemipelagic sediments led to death of buildings. Similar palaeogeographic changes and geodynamic evolution have been recently described from different structures in North Africa, Western Europe and North America.Le Lías du Haut Atlas central marocain présente diverses"bioconstructions carbonatées de type Mud-mound bien développées au passage Sinémurien inférieur- Sinémurien supérieur au Sud de Midelt.

    The 16 uranium deposits of the Crouzille (Haute-Vienne, France) have produced 25000 tons of uranium between 1950 and 1995. The uranium content of the ores ranges from 1 to 10/1000. The main production came from the underground exploitation up to 300 m of depth. This book presents the historical aspects of this industrial and human epopee and describes with details the underground exploitation of the ore, its processing and the rehabilitation of the site after the mines have closed down.

    Full Text Available Confined to parks and forests, nature in French urban areas has been used as an instrument for urban planners and developers. Recent urban projects have sought to give natural systems a fuller role in territorial development. This new function can be considered a radically new approach. At the same time, current redevelopment projects must also integrate existing facilities. The redevelopment of the banks of the Seine by the Hauts-de-Seine council is a good example of this new role that nature can play in urban revitalisation. Maps show the constraints and issues that must be taken into account.

    Summary Les accidents électriques par haute tension (AEHT) provoquent des brûlures profondes par effet Joule le long des axes vasculo-nerveux entre les points d'entrée et de sortie, qui sont le siège de lésions délabrantes. Les Auteurs rapportent une série de dix cas d'AEHT admis au service de chirurgie réparatrice et de brûlés de l'Hôpital Ibn Sina de Rabat à travers laquelle ils étudient les caractéristiques épidémiologiques, cliniques et thérapeutiques. Tous les patients étaient des adultes de sexe masculin dont l'âge moyen était de 31 ans. Dans 70% des cas, ces brûlures étaient secondaires à un contact avec les distributeurs d'électricité avec une surface brûlée inférieure à 20%. Le traitement des lésions électrothermiques a nécessité des interventions itératives avec amputation des segments de membres nécrosés dans 70% des cas, dont les suites étaient marquées par des séquelles fonctionnelles invalidantes. La prévention des AEHT, en particulier pour les accidents du travail au sein des professions exposées, reste fondamentale. PMID:21991124

    Application of the qualitative theory of dynamic systems to analysis of homogeneous cosmological models is described. Together with the well-known cases, requiring ideal liquid, the properties of cosmological evolution of matter with dissipative processes due to viscosity are considered. New cosmological effects occur, when viscosity terms being one and the same order with the rest terms in the equations of gravitation or even exceeding them. In these cases the description of the dissipative process by means of only two viscosity coefficients (volume and shift) may become inapplicable because all the rest decomposition terms of dissipative addition to the energy-momentum in velocity gradient can be large application of equations with hydrodynamic viscosty should be considered as a model of dissipative effects in cosmology

    On August 3, 1999, the French government gave the permission to the national agency of radioactive wastes (ANDRA) to build up a research laboratory devoted to the feasibility study of a facility for the reversible disposal of high level and long living radioactive wastes in deep geologic beds. The site retained is located at Bure, at the boundary of the Meuse and Haute-Marne departements. Before starting the construction of this research facility, the ANDRA has carried out a careful survey of the initial environmental status of the site which will serve as a reference. This brochure presents the results of this survey: geo-morphology, agriculture, natural ecosystems, radioecology, sound levels, air quality, surface and groundwater quality. The ANDRA has implemented an environmental monitoring plan for each phase of the development of the project. (J.S.)

    In front of increase of conflicts finding big environmental projects, approval of social players quickly became an essential condition in their realization, raising social acceptability to rank of priorities. To illustrate my search on social acceptability, I chose to study project of presence of an industrial wind farm on municipalities of Allas Bocage and Nieul-le-Virouil in Haute Saintonge. Methodology rests on participating observation which authorizes understanding of a group. If the social acceptability is a fragile and slow process to be built, the social unacceptability takes root durably. My problem rests on the process of construction of the social unacceptability, fruit of a different logic between promoter and local actors. My results allow me to highlight the processual dimension of the social unacceptability of one project. (author)

    Document available in extended abstract form only. The GEO database (geo-scientific database of the Meuse/Haute-Marne Center) is a tool developed by Andra, with a view to group in a secured computer form all data related to the acquisition of in situ and laboratory measurements made on solid and fluid samples. This database has three main functions: - Acquisition and management of data and computer files related to geological, geomechanical, hydrogeological and geochemical measurements on solid and fluid samples and in situ measurements (logging, on sample measurements, geological logs, etc). - Available consultation by the staff on Andra's intranet network for selective viewing of data linked to a borehole and/or a sample and for making computations and graphs on sets of laboratory measurements related to a sample. - Physical management of fluid and solid samples stored in a 'core library' in order to localize a sample, follow-up its movement out of the 'core library' to an organization, and carry out regular inventories. The GEO database is a relational Oracle data base. It is installed on a data server which stores information and manages the users' transactions. The users can consult, download and exploit data from any computer connected to the Andra network or Internet. Management of the access rights is made through a login/ password. Four geo-scientific explanations are linked to the Geo database, they are: - The Geosciences portal: The Geosciences portal is a web Intranet application accessible from the ANDRA network. It does not require a particular installation from the client and is accessible through the Internet navigator. A SQL Server Express database manages the users and access rights to the application. This application is used for the acquisition of hydrogeological and geochemical data collected on the field and on fluid samples, as well as data related to scientific work carried out at surface level or in drifts

  11. Combining functional weed ecology and crop stable isotope ratios to identify cultivation intensity: a comparison of cereal production regimes in Haute Provence, France and Asturias, Spain.

    This investigation combines two independent methods of identifying crop growing conditions and husbandry practices-functional weed ecology and crop stable carbon and nitrogen isotope analysis-in order to assess their potential for inferring the intensity of past cereal production systems using archaeobotanical assemblages. Present-day organic cereal farming in Haute Provence, France features crop varieties adapted to low-nutrient soils managed through crop rotation, with little to no manuring. Weed quadrat survey of 60 crop field transects in this region revealed that floristic variation primarily reflects geographical differences. Functional ecological weed data clearly distinguish the Provence fields from those surveyed in a previous study of intensively managed spelt wheat in Asturias, north-western Spain: as expected, weed ecological data reflect higher soil fertility and disturbance in Asturias. Similarly, crop stable nitrogen isotope values distinguish between intensive manuring in Asturias and long-term cultivation with minimal manuring in Haute Provence. The new model of cereal cultivation intensity based on weed ecology and crop isotope values in Haute Provence and Asturias was tested through application to two other present-day regimes, successfully identifying a high-intensity regime in the Sighisoara region, Romania, and low-intensity production in Kastamonu, Turkey. Application of this new model to Neolithic archaeobotanical assemblages in central Europe suggests that early farming tended to be intensive, and likely incorporated manuring, but also exhibited considerable variation, providing a finer grained understanding of cultivation intensity than previously available.

Tout en permettant d’enseigner des contenus de programmes scolaires, les actions réalisées ont également été l’occasion d’enseigner des stratégies auxiliaires de promotion de meilleures habitudes alimentaires et de réduction du problème de l’élimination des déchets organiques. La culture de potagers dans des caisses peut se faire dans de petits espaces et les déchets crus de légumes jetés normalement à la poubelle ont pu être réutilisés  comme compost organique pour le potager. Ce genre d’activités contribue à faire de l’école, non seulement un espace d’éducation formelle, mais également un centre d’enseignement et de diffusion de mesures susceptibles de produire des résultats immédiats en termes de qualité de la vie dans la communauté scolaire.En una escuela pública (Niterói, RJ - Brasil de enseñanza media, se estimularon iniciativas que implican nociones de educación medioambiental y científica mediante actividades prácticas y dinámicas desarrolladas con alumnos de 15 a 17 años, a lo largo de un año lectivo. Para cada actividad hubo una organización propia, con objetivos específicos, metas, y un calendario de trabajo para el cumplimiento de las tareas, así como la participación escalonada de los alumnos implicados.

    Full Text Available La première partie de cette étude a consisté à observer et à tenter d'interpréter l'action des conditions de fonctionnement et des paramètres de réglage du moteur sur la tendance au cliquetis à haut régime. On a montré ensuite que les différentes familles chimiques d'hydrocarbures qui constituent les carburants classiques présentent chacune un comportement bien distinct en fonction de la richesse, de la pression et de la température d'admission. On a également étudié l'influence de la teneur en plomb du carburant et du type d'alkyle de plomb employé. Quelques expériences ont été effectuées afin de déterminer l'incidence d'une réduction de un point de taux de compression sur l'exigence en octane à haut régime et sur l'action des caractéristiques de composition du carburant. Enfin, en déterminant le pourcentage de cycles soumis au cliquetis pour différentes avances à l'allumage, il a été possible de fournir quelques indications permettant de mieux caractériser l'intensité du phénomène. The first part of this study consists in observing and trying to interpret the effect of operating conditions and engine tuning parameters on the tendency for high-speed knocking to appear. The different chemical families of the hydrocarbons making up conventional fuels are shown to each have a quite different behavior depending on the fuel-air equivalency ratio and the admission pressure and temperature. The influence of the lead content in the fuel and of the type of lead alkyl used is also studied. Some experiments were performed to determine the influence of a one-point reduction in the compression ratio on the high-speed octane requirement and on the effect of fuel composition properties. Lastly, by determing the percentage of cycles accompanied by knocking at different spark advances, some indications were found for better characterizing the intensity of the phenomenon.

    Using structural evolution data and a method permitting the calculation of elastic constants and Grüneisen parameters, the thermal expansion of two high T_c superconductors is interpreted. It is shown that the superconductors YBaCuO (123) and BiSrCaCuO (2212) present strongly different elastic and anharmonic properties. En appliquant une méthode déjà mise au point sur d'autres composés (Gavarri, 1981), l'évolution structurale de deux supraconducteurs à haute T_c est interprétée par le biais de leurs compressibilités anisotropes et de leurs coefficients de Grüneisen, obtenus par diffraction de neutrons et de rayons X. On montre ici que les supraconducteurs YBaCuO (123) et BiSrCaCuO (2212) diffèrent considérablement par leurs compressibilités anisotropes et par leurs coefficients de Grüneisen.

Des corrélations et des résultats prévisionnels sont présentés à partir de l'équation de Peng-Robinson (t-mPR translatée et modifiée. Il est montré que l'on rencontre de sérieux problèmes à haute pression dans le cas où l'on utilise des coefficients d'interaction extrapolés. Les prévisions des pressions de saturation des gaz à condensats sont plus satisfaisantes lorsque les paramètres d'interaction binaire sont obtenus à partir d'une corrélation des points de rosée à haute pression. Les prévisions concernant les volumes et les compositions sont remarquables à condition que l'on définisse les paramètres des équations d'état sur la base des données ELV binaires. Des résultats contradictoires sont obtenus avec différentes méthodes dans l'estimation des propriétés critiques des hydrocarbures de poids moléculaires élevés. Les expressions généralisées pour la translation de volume apparaissent comme très efficaces même à très hautes températures et très hautes pressions (jusqu'à 2000 bar.

    Full Text Available Andra is in charge of studying the feasibility of a disposal facility for longlived high-level nuclear waste (LL-HLW in a deep geological environment. With this aim, dedicated experiments have been carried out for several years at the Meuse/Haute Marne Underground Research Laboratory excavated in a 500 m deep argillaceous rock formation. These experiments include determining the feasibility of the excavation of disposal cells for LL-HLW, consisting of 40 meter long, 70 cm in diameter, horizontal cased micro tunnels. The hydro mechanical impact of the excavation of such openings on the rock mass behaviour is continuously monitored as well as their mean term mechanical behaviour. Since LL-HLW produce heat, the impact of temperature on the surrounding rock mass and on the micro tunnel steel casing will also be studied. Specific instrumentation has been developed to study this impact. The first step of the microtunnel excavation tests, carried out in 2009, has led to improving the excavation method and the drilling machine. These improvements will be tested in the next step of the excavation tests planned for 2010. The THM experiment dedicated to studying the behaviour of the rock mass under thermal solicitation started early 2010. The behaviour of a steel casing in contact with the rock mass and under thermal solicitation will be studied in an experiment scheduled to start in September 2010.

  5. Physical and numerical modelling of permafrost dynamic during a climatic cycle: implications for Meuse - Haute-Marne site

    International Nuclear Information System (INIS)

    Regnier, D.

    2012-01-01

    This manuscript deals about works realized on the permafrost modelling in porous media and its impact on the hydrogeological circulations. These are parts of the Andra's studies on the nuclear waste storage and, on the environmental studies of the Meuse/Haute-Marne (MHM) site. During a climatic cycle, cold periods can generate permafrost (ground with temperature lower than 0 C for 2 consecutive years). This peri-glacial structure propagates towards deep geological layers, and, due to its very low permeability, can stop the flow of water bodies like aquifers. This work presents the elaboration of two numerical models (with Cast3M code (CEA)): (i) a model with thermal conduction, used for the study of a cold wave propagation in porous media with phase transition (water-ice); (ii) a more complex model, managing the thermo-hydraulic coupling of ground phenomenon (conduction, convection and transition of phase). After validation, these two models offer three axes of development: (i) benchmark proposition by the study of two generic test-cases; (ii) study of the local air temperature signal on MHM site: importance of high frequency temperature variations (centennial scale) for permafrost depth and stability; (iii) study of the dynamics of a thermal discontinuity in a typical hydrological system river-plain: closure time of the system by the permafrost according to various parameters (temperatures, geothermal flow, hydrological flow directions).

    Full Text Available Water vapor total column measurements at Observatoire de Haute Provence (5°42´ E, +43°55´ N, south of France, were obtained using observations of astronomical objects made between July 1994 and December 2004 on the 193-cm telescope with the high-resolution spectrometer Elodie. Spectra of stars, nebulae, and other astronomical objects were taken regularly during 10 years. More than 18 000 spectra from 400 nm to 680 nm are available on-line in the Elodie Archive. This archive, usually explored by astronomers, contains information to study the atmosphere of the Earth. Water vapor absorption lines appear in the visible in delimited bands that astronomers often avoid for their spectral analysis. We used the Elodie Archive with two objectives: firstly, to retrieve seasonal variability and long-term trend of atmospheric water vapor, and secondly, to remove signatures in spectra for further astronomical or geophysical use. The tools presented here (the workflow, the interoperable Elodie Archive and the web service Tellodie are developed following, when possible, formats and standards recommended by the International Virtual Observatory Alliance.

  7. REFLECT: Logiciel de restitution des reflectances au sol pour l'amelioration de la qualite de l'information extraite des images satellitales a haute resolution spatiale

    Science.gov (United States)

    Bouroubi, Mohamed Yacine

    Multi-spectral satellite imagery, especially at high spatial resolution (finer than 30 m on the ground), represents an invaluable source of information for decision making in various domains in connection with natural resources management, environment preservation or urban planning and management. The mapping scales may range from local (finer resolution than 5 m) to regional (resolution coarser than 5m). The images are characterized by objects reflectance in the electromagnetic spectrum witch represents the key information in many applications. However, satellite sensor measurements are also affected by parasite input due to illumination and observation conditions, to the atmosphere, to topography and to sensor properties. Two questions have oriented this research. What is the best approach to retrieve surface reflectance with the measured values while taking into account these parasite factors? Is this retrieval a sine qua non condition for reliable image information extraction for the diverse domains of application for the images (mapping, environmental monitoring, landscape change detection, resources inventory, etc.)? The goals we have delineated for this research are as follow: (1) Develop software to retrieve ground reflectance while taking into account the aspects mentioned earlier. This software had to be modular enough to allow improvement and adaptation to diverse remote sensing application problems; and (2) Apply this software in various context (urban, agricultural, forest) and analyse results to evaluate the accuracy gain of extracted information from remote sensing imagery transformed in ground reflectance images to demonstrate the necessity of operating in this way, whatever the type of application. During this research, we have developed a tool to retrieve ground reflectance (the new version of the REFLECT software). This software is based on the formulas (and routines) of the 6S code (Second Simulation of Satellite Signal in the Solar Spectrum) and on the dark targets method to estimated the aerosol optical thickness, representing the most difficult factor to correct. Substantial improvements have been made to the existing models. These improvements essentially concern the aerosols properties (integration of a more recent model, improvement of the dark targets selection to estimate the AOD), the adjacency effect, the adaptation to most used high resolution (Landsat TM and ETM+, all HR SPOT 1 to 5, EO-1 ALI and ASTER) and very high resolution (QuickBird et Ikonos) sensors and the correction of topographic effects with a model that separate direct and diffuse solar radiation components and the adaptation of this model to forest canopy. Validation has shown that ground reflectance estimation with REFLECT is performed with an accuracy of approximately +/-0.01 in reflectance units (for in the visible, near-infrared and middle-infrared spectral bands) even for a surface with varying topography. This software has allowed demonstrating, through apparent reflectance simulations, how much parasite factors influencing numerical values of the images may alter the ground reflectance (errors ranging from 10 to 50%). REFLECT has also been used to examine the usefulness of ground reflectance instead of raw data for various common remote sensing applications in domains such as classification, change detection, agriculture and forestry. In most applications (multi-temporal change monitoring, use of vegetation indices, biophysical parameters estimation, etc.) image correction is a crucial step to obtain reliable results. From the computer environment standpoint, REFLECT is organized as a series of menus, corresponding to different steps of: input parameters introducing, gas transmittances calculation, AOD estimation, and finally image correction application, with the possibility of using the fast option witch process an image of 5000 by 5000 pixels in approximately 15 minutes.

    Full Text Available New concerns have appeared recently from the European and American consumers about quality, safety and environmental impact of the food products. In the particular case of European countries, the coming back of traditional products with a high sentimental value should be noticed. To fit the forthcoming demand of the consumer, the Oils and Fats industry have to develop a new approach based on alternative technologies that may emerge from the research with very specific objectives: no solvents, mild technologies, less energy consumption and final wastes. The purpose of this article is to discuss about the new biological tools capable to generate alternative ways for the oil elaboration: use of enzymes for destructuration of the vegetal or animal tissues and the subsequent utilisation of membrane techniques for the separation and purification steps. These new technologies involving less heat and mechanical stress to the oil, lead to a better “native” quality of the final products. However, fundamental research is needed on the separation mechanisms of those complex mixtures to optimise the process and prepare the transfer to the industrial conditions. The present article reports a contribution on the aqueous extraction of rapeseed oil as an example

    The Green Valley reclaimed coal refuse site, near Terre Haute, Ind., was mined for coal from 1948 to 1963. Subsurface coal was cleaned and sorted at land surface, and waste material was deposited over the native glacial till. Approximately 2.7 million cubic yards of waste was deposited over 159 acres (92.3 hectares) in tailings ponds and gob piles. During 1993, the Indiana Department of Natural Resources, Division of Reclamation, improved the site by grading gob piles, filling tailings ponds, and covering the refuse with a layer of glacial drift. During 2008, the Division of Reclamation and U.S. Geological Survey initiated a cooperative investigation to characterize the hydrogeology of the site and construct a calibrated groundwater flow model that could be used to simulate the results of future remedial actions. In support of the modeling, a data-collection network was installed at the Green Valley site to measure weather components, geophysical properties, groundwater levels, and stream and seep flow. Results of the investigation indicate that (1) there is negligible overland flow from the site, (2) the prevailing groundwater-flow direction is from northeast to southwest, with a much smaller drainage to the northeast, (3) there is not a direct hydraulic connection between the refuse and West Little Sugar Creek, (4) about 24 percent of the groundwater recharge emerges through seeps, and water from the seeps evaporates or eventually flows to West Little Sugar Creek and the Green Valley Mine Pond, and (5) about 72 percent of groundwater recharge moves vertically downward from the coal refuse into the till and follows long, slow flow paths to eventual dischage points.

    Document available in extended abstract form only. Due to its low permeability (10 -18 to 10 -20 m 2 ), the Meuse-Haute/Marne argillite is chosen as the candidate host rock for the geological disposal of high-level radioactive waste by 'Agence Nationale de gestion des Dechets Radioactifs' (ANDRA). During the excavation of the underground tunnel in argillite formation, the Excavation Damaged Zone (EDZ) is expected to develop due to the stress redistribution during excavation and subsequent rock convergence. The nucleation and propagation of microcracks in EDZ can consequently affect the poro-mechanical behavior of the host rock. Therefore, it is of crucial importance to study the poro-mechanical behavior of Meuse-Haute/Marne argillite under the influence of stress induced microcracks. For this purpose, this paper presents the original experimental results of drained and undrained triaxial compression tests as well as evolution of Biot's coefficient during hydrostatic and deviatoric loading of saturated Meuse-Haute/Marne argillite. The size of samples used in the present work is 20x20 mm in order to reduce the saturating time. The axis of the cylindrical sample is perpendicular to the bedding planes. The test system is placed in an insulated room and a temperature control system is used to maintain a constant temperature of 20 ±0.2 C. The saturation condition is an important factor for the determination of the mechanical and poro-elastic properties of saturated argillite. Thus, for each sample, after putting into the triaxial cell, the confining pressure is loaded to 2 MPa and we inject distilled water both at the injection and outlet faces in order to insure the pore pressure at the two faces hold at 1 MPa. This procedure will be keep to 72 hours. Then, the pore pressure at the injection face is increased to 1.5 MPa, and we record the pore pressure at the outlet face. Once the pore pressure at the outlet face reaches the same value at injection face, the sample is

    Full Text Available Qualitative research in the health sciences has had to overcome many prejudices and a number of misunderstandings, but today qualitative research is as acceptable as quantitative research designs and is widely funded and published. Writing the proposal of a qualitative study, however, can be a challenging feat, due to the emergent nature of the qualitative research design and the description of the methodology as a process. Even today, many sub-standard proposals at post-graduate evaluation committees and application proposals to be considered for funding are still seen. This problem has led the researcher to develop a framework to guide the qualitative researcher in writing the proposal of a qualitative study based on the following research questions: (i What is the process of writing a qualitative research proposal? and (ii What does the structure and layout of a qualitative proposal look like? The purpose of this article is to discuss the process of writing the qualitative research proposal, as well as describe the structure and layout of a qualitative research proposal. The process of writing a qualitative research proposal is discussed with regards to the most important questions that need to be answered in your research proposal with consideration of the guidelines of being practical, being persuasive, making broader links, aiming for crystal clarity and planning before you write. While the structure of the qualitative research proposal is discussed with regards to the key sections of the proposal, namely the cover page, abstract, introduction, review of the literature, research problem and research questions, research purpose and objectives, research paradigm, research design, research method, ethical considerations, dissemination plan, budget and appendices.

    Qualitative research methods are a robust tool for chaplaincy research questions. Similar to much of chaplaincy clinical care, qualitative research generally works with written texts, often transcriptions of individual interviews or focus group conversations and seeks to understand the meaning of experience in a study sample. This article describes three common methodologies: ethnography, grounded theory, and phenomenology. Issues to consider relating to the study sample, design, and analysis are discussed. Enhancing the validity of the data, as well reliability and ethical issues in qualitative research are described. Qualitative research is an accessible way for chaplains to contribute new knowledge about the sacred dimension of people's lived experience.

    The study of specimens contaminated by different amounts of carbon shows a deleterious effect of this element in the resistance of zirconium to high temperature oxidation (700 to 900 deg. C). We drew the following results: a) the white spots or 'pimples' observed by numerous authors seem to be caused by the oxidation of precipitated carbides. We suggest a mechanism of formation and growth of these pimples; b) for a certain carbon content, the resistance to oxidation is increased by an uniform dispersion of the carbide phase and decreased, for instance, by extrusion textures. In this case, for the more marked textures, the more oriented corrosion was observed; c) by burning of the carbide phase it can result a second reaction increasing the corrosion rate; d) thin zirconium foils undergoes dimensional changes when scaling in oxygen. This unusual feature is also subordinated to carbon content and specially to the carbide phase dispersion. (author) [French] L'etude d'echantillons differemment contamines par le carbone nous a permis de mettre en evidence l'action particulierement nocive de cet element sur la resistance du zirconium a la corrosion par l'oxygene a haute temperature (700 a 900 deg.

Nous suggerons un mecanisme de formation et de croissance de ces pustules, b) la tenue du metal est d'autant meilleure que, pour une meme teneur en carbone, la phase 'carbure' est plus uniformement dispersee. En consequence, si la dispersion est mauvaise, on observe selon l'axe des textures de filage, par exemple, une corrosion preferentielle d'autant plus accentuee que les textures sont plus marquees, c) la combustion de la phase 'carbure' peut engendrer une reaction secondaire susceptible d'accroitre la cinetique de corrosion, d) l'expansion des grandes faces d

    From a geomechanical point of view, the safety of an underground storage for the radioactive waste requires to characterize the damaged zone induced by the shaft sinking for the storage cavities. Then, the objective of this thesis is to simulate the hydro-mechanical response of the East argilites to the shaft sinking for the Meuse/Haute-Marne underground laboratory, in order to compare the results to the in situ measurements which will be recorded in 2005 (REP experiment). Firstly we have analysed all the mechanical tests which had been carried out from 1995 to 2001. We have observed that each series has his own coherence, in terms of elastic parameters, mechanical strength or creep capacity. But there are some strong differences between the series. These differences, which are due to the experimental protocols and not to the material itself, have shown three important results: the re-saturation phases imposed by several laboratories have deteriorated the mechanical properties of the East argilites, the existence of an effective stress is not evident for these argilites, and their mechanical strength increases when they are dried. From these tests, we have distinguished three mechanisms that produce irreversible strains: compaction, pre-failure, failure. We have described each of them by a straightforward elasto-plastic model, based on the Mohr-Coulomb or Drucker-Prager criterion, with a linear softening. Thus we obtain a complete rheological model for the East argilites by considering simultaneously the three mechanisms (multi-criterion plasticity). Lastly, from the modelling we carried out, we can conclude that: to take into account the irreversible strains that occur before the failure has a great influence on the seize of the failure zone around the shaft (it is very small with respect to the case where the behaviour is elastic until the failure); the pore pressure diffusion modifies very little the mechanical response of the massif (the plastic strains created

    Document available in extended abstract form only. In order to test the feasibility of disposing High-Level and Long-Lived Wastes (HLW-LL) in Callovo- Oxfordian clay formation (COx), the French National Radioactive Waste Management Agency (ANDRA) has carried out scientific and engineering investigations in the Meuse-Haute-Marne Underground Research Laboratory (URL) since November 1999. The COx (Figure 1) is of a special interest because of its very favourable characteristics for being a possible host rock for the disposal of radioactive waste. The project OHZ (Observation and Monitoring of the EDZ) was initiated in 2008 by ANDRA. In the framework of this project, a Mine-by experiment was performed in the niche GCS. The excavation was started on 29.01.2008. Displacement and pore pressure evolution during the excavation was measured by different sensors. Within the cooperation between BGR and ANDRA numerical calculations have been done using the code RockFlow to understand the hydraulic and mechanical (HM) coupling mechanisms of Callovo-Oxfordian clay-stone observed during the Mine-by experiment. Modelling results: With regard to the bedding of COx a transverse isotropy approach was applied. Thus the anisotropy effects caused by the bedding have been considered in coupled HM models (Massmann, 2009). Intensive parameter studies in comparison with measured deformation and pore pressure data have been conducted to reduce modelling uncertainties. Fully saturated models yield very precise results in the far field wherein excavation effect has its lower impact. Rapid decline of pore pressure and continuously increasing deformation subsequent to excavation in the near field could not be interpreted even taking shrinkage and partially saturation into consideration. During the Mine-by test, overpressures on sidewalls and reduced pressures on roof and floor were measured due to the mechanical effect on pore pressure which is induced by the bedding. Good agreement between

    Full Text Available Qualitative content analysis is commonly used for analyzing qualitative data. However, few articles have examined the trustworthiness of its use in nursing science studies. The trustworthiness of qualitative content analysis is often presented by using terms such as credibility, dependability, conformability, transferability, and authenticity. This article focuses on trustworthiness based on a review of previous studies, our own experiences, and methodological textbooks. Trustworthiness was described for the main qualitative content analysis phases from data collection to reporting of the results. We concluded that it is important to scrutinize the trustworthiness of every phase of the analysis process, including the preparation, organization, and reporting of results. Together, these phases should give a reader a clear indication of the overall trustworthiness of the study. Based on our findings, we compiled a checklist for researchers attempting to improve the trustworthiness of a content analysis study. The discussion in this article helps to clarify how content analysis should be reported in a valid and understandable manner, which would be of particular benefit to reviewers of scientific articles. Furthermore, we discuss that it is often difficult to evaluate the trustworthiness of qualitative content analysis studies because of defective data collection method description and/or analysis description.

    Andra is exploring several options for the disposal of low-level long-lived waste (LLW-LL). With the French Government's approval, in June 2008 Andra began looking around France for a site to build an LLW-LL repository. In late 2008 it provided the Government with a report analysing the geological, environmental and socio-economic aspects of the forty odd municipalities that expressed an interest in the project. After the withdrawal of the two municipalities chosen in 2009 to conduct geological investigations, the government asked Andra to re-explore the various management options for graphite and radium-bearing waste, focusing in particular on ways to manage these types of waste separately. The High Committee for Transparency and Information on Nuclear Safety (HCTISN) created a working group to provide feedback on the search for a site for LLW-LL. Andra submitted a report to the Government in late 2012. This report contains proposals for continuing the search and draw in particular on the HCTISN's recommendations.

A quantification of the spatio-temporal dynamics of urbanization is crucial to apprehend urban morphology and its ecological effects, in order to support sustainable urban planning. This study aimed at understanding the spatial urban growth of Lubumbashi city based on the analysis of six SPOT satellites images. With the exception of the 1996-2002 period, Lubumbashi city underwent a high average annual growth rate exceeding that observed for other cities in sub-Saharan Africa. Between 1989 and 2014, the built-up percentage increased from 6 % to 20 %. Our results suggest that the urbanization of Lubumbashi city followed a complex diffusion-coalescence model. The main reason of this perturbation is the combination of the rapid demographic growth with an inappropriate urban growth management.

    A crystallization age of 432sub(-10)/sup +20/Ma has been determined for the 'La Borie' eclogite (Haut-Allier, France), by U-Pb dating on zircons. This age is yielded by the upper intercept with the Concordia curve. In agreement with recent dates obtained in the southern part of the Massif Central, in Brittany and in Vendee, these data indicate that the high-pressure/high-temperature-metamorphic phase representative of the pre-Variscan evolution of the western Europe, took place at the Silurian/Ordovician boundary. This high-pressure/high-temperature metamorphism could be significant of subduction processes more or less synchronous, preceeding the main continental collision responsible of the Variscan belt.

    A crystallization age of 432sub(-10) +20 Ma has been determined for the 'La Borie' eclogite (Haut-Allier, France), by U-Pb dating on zircons. This age is yielded by the upper intercept with the Concordia curve. In agreement with recent dates obtained in the southern part of the Massif Central, in Brittany and in Vendee, these data indicate that the high-pressure/high-temperature-metamorphic phase representative of the pre-Variscan evolution of the western Europe, took place at the Silurian/Ordovician boundary. This high-pressure/high-temperature metamorphism could be significant of subduction processes more or less synchronous, preceeding the main continental collision responsible of the Variscan belt.

    2008-01-01

    For more than 50 years, more than 200 sites were prospected and mined to extract uranium in France. Haute-Vienne, in the Midwest of the country, played a leading position. Up to the present, rehabilitation of the sites is nearly complete and surveillance is the way of assessing its efficiency. In 2003, AREVA NC was asked to produce a report presenting the results of the ten-year (1994-2003) monitoring and surveillance of the rehabilitated sites and their environment. In 2006, the Institute of Radioprotection and Nuclear Safety (IRSN) was asked to perform the technical review of this report. This review led IRSN to recommend actions to improve the monitoring systems and minimise discharges to the environment. Results and recommendations were presented to and discussed with the pluralistic expert group (GEP) created in 2006 by the French ministries of environment, health and industry. (author)

    Le travail de recherche effectue dans le cadre de ce projet de doctorat a permis la mise au point d'une methode de mesure des pertes ac destinee a l'etude des supraconducteurs a haute temperature critique. Pour le choix des principes de cette methode, nous nous sommes inspires de travaux anterieurs realises sur les supraconducteurs conventionnels, afin de proposer une alternative a la technique electrique, presentant lors du debut de cette these des problemes lies a la variation du resultat des mesures selon la position des contacts de tension sur la surface de l'echantillon, et de pouvoir mesurer les pertes ac dans des conditions simulant la realite des futures applications industrielles des rubans supraconducteurs: en particulier, cette methode utilise la technique calorimetrique, associee a une calibration simultanee et in situ. La validite de la methode a ete verifiee de maniere theorique et experimentale: d'une part, des mesures ont ete realisees sur des echantillons de Bi-2223 recouverts d'argent ou d'alliage d'argent-or et comparees avec les predictions theoriques donnees par Norris, nous indiquant la nature majoritairement hysteretique des pertes ac dans nos echantillons; d'autre part, une mesure electrique a ete realisee in situ dont les resultats correspondent parfaitement a ceux donnes par notre methode calorimetrique. Par ailleurs, nous avons compare la dependance en courant et en frequence des pertes ac d'un echantillon avant et apres qu'il ait ete endommage. Ces mesures semblent indiquer une relation entre la valeur du coefficient de la loi de puissance modelisant la dependance des pertes avec le courant, et les inhomogeneites longitudinales du courant critique induites par l'endommagement. De plus, la variation en frequence montre qu'au niveau des grosses fractures transverses creees par l'endommagement dans le coeur supraconducteur, le courant se partage localement de maniere a peu pres equivalente entre les quelques grains de matiere

    Full Text Available Lorsqu'on utilise un système d'acquisition rapide de données sur moteur, il se pose souvent le problème d'associer des grandeurs calculées, comme le volume de la chambre de combustion, à des grandeurs mesurées comme la pression dans le cylindre. II est alors indispensable de synchroniser avec une grande précision absolue ces deux grandeurs en repérant avec soin au moins un point de référence de la cinématique bielle-manivelle. Dans la méthode développée ici on a choisi de déterminer la position angulaire du vilebrequin correspondant au Point Mort Haut (PMH grâce à l'exploitation du signal de pression-cylindre acquis en compression-détente sans combustion, le moteur étant entraîné en rotation. Le principe du calage consiste à calculer l'écart existant entre le PMH et l'angle de la pression maximale qui est aisément repérable. Basée sur des considérations thermodynamiques théoriques, cette méthode de calage a été testée avec succès au cours d'essais effectués sur divers moteurs dont on a fait varier en particulier le rapport volumétrique, le remplissage et les pertes à la segmentation. La précision de la méthode est de l'ordre de 1/10e de degré de rotation vilebrequin. When a fast data-acquisition system is used for an engine, the problem often arises of associating both calculated data, such as combustion chamber volume, and measured data, such as pressure inside the cylinder. It then becomes indispensable to synchronize these two data with great absolute accuracy by carefully determining at least a reference point in the kinematics of the connecting-rod/crank shaft assembly. In the method developed here, we have chosen to determine the angular position of the crankshaft corresponding to top dead center (TDC by making use of the cylinder-pressure signal recorded during compression/expansion without combustion for motored engine. The calibration principle consists in calculating the shift between TDC and the

    The cold cathode reflex discharge develops a cathode sheath of several hundreds of volts, which accelerates electrons released from the cathode to high velocities along the lines of the axial magnetic field. On the studied pressure range (4.10{sup -4} torr < p < 2.10{sup -2} torr) the plasma density is about 10{sup 11} cm{sup -3}. Under certain conditions high frequency (1 5000 MHz) instabilities appear. These instabilities are found to profoundly modify the mean characteristics of the discharge. In particular, particle flow across the lines of magnetic field is found to be considerably greater than that predicted by classical diffusion theory. Theoretical considerations are presented with complementary experimental results. They show that the high frequency instabilities are a result of the fast electronic assembly accelerated through the cathode sheath. (author) [French] Dans certaines conditions, qui sont precisees, des instabilites a haute frequence (1 5000 MHz) se developpent dans la decharge reflex a cathodes froides. Lorsque le plasma (n {approx_equal}10{sup 11} cm{sup -3}) est instable, les caracteristiques moyennes de la decharge sont profondement alterees. Les fuites de particules a travers les lignes de forces du champ magnetique statique applique deviennent en particulier trop importantes pour que le seul effet classique des collisions binaires puisse les expliquer. L'ionisation du gaz est assuree par une assemblee electronique qui acquiert dans les gaines cathodiques ({approx_equal} 500 volts) une vitesse, parallele au champ magnetique, importante. La discussion de resultats theoriques et une experience complementaire montrent que cette population d'electrons rapides, tres distincte de celle des electrons lents du plasma pour les pressions les plus faibles du domaine etudie (4.10{sup -4} torr < p < 2.10{sup -2} torr), est responsable des instabilites a haute frequence observees.

    Callovian-Oxfordian (COX) indurated clay formation is currently studied by Andra in the 'Meuse/Haute-Marne' (MHM) area for hosting a potential repository of high level, long-lived radioactive waste. IRSN is conducting studies in support of the safety evaluation of the geological disposal programme developed by Andra. IRSN, in collaboration with the Paris School of Mines, develops conceptual and numerical models of the underground water flows throughout the Paris sedimentary basin. The calibrated numerical model correctly represents the hydraulic heads and water salinities collected throughout the basin. At the MHM scale however, several flow patterns can still reproduce the measured heads, some of them assuming specific flow pathways along regional tectonic trends. Considering or not such tectonic trends in the model has however an impact on the estimated radionuclide transfer times to the outlets. Even though most ANDRA and IRSN geochemical analyses suggest a dominant diffusive transport across the COX between the underlying Dogger and overlying Oxfordian aquifers, few data point out the possible existence of local vertical connections across major tectonic structures. In order to select the most plausible options for the numerical modelling, IRSN compiled published studies and carried out fieldwork analysis to provide new data for its hydrogeological conceptual model. Relevant geological data can be considered both at the kilometre scale and at the metre scale. At the kilometre scale, the litho-stratigraphic scheme both for Dogger and Oxfordian series had previously been documented in the MHM area. Regional sedimentologic and diagenetic models are available for the Oxfordian aquifer and partially for the Dogger aquifer. Our fieldwork analysis complete these models thanks to new correlations pointed out during detailed iso-hyps mapping performed by G2R laboratory, southeast from the MHM area. Unlike the Kimmeridgian and COX sedimentary piles, which are

(author) [French] L'etude de l'utilisation des echangeurs d'ions a haute temperature a ete essentiellement faite en vue de l'epuration de l'eau des reacteurs. On connait l'interet qu'il y a a garder dans un circuit de reacteur de l'eau de tres haute resistivite (plusieurs centaines a quelques millions {omega}.cm): abaissement de la corrosion, abaissement du taux de radiolyse, abaissement de la radioactivite des circuits et canalisations, les elements autres que les constituants de l'eau transportes par celle-ci devenant generalement radioactifs par leur passage au coeur du reacteur. Si la circulation d'eau se fait a des temperatures inferieures a 45 deg. C, les resines echangeuses d'ions organiques utilisees en lit melange resolvent tres bien le probleme de l'epuration en continu. Par contre, pour des temperatures plus elevees surtout au-dessus de 100 deg. C, leur utilisation n'est pas possible, la degradation de ces hauts polymeres etant tres rapide. De meme, l'action des rayonnements, par exemple ceux des produits fixes par les echangeurs d'ions, detruit irremediablement les chaines organiques constituant le squelette de ces echangeurs. Nous avons donc cherche d'es composes pouvant assurer une bonne deionisation de l'eau, mais de structures telles qu'elles ne soient pas deteriorees par l'action de la temperature et des rayonnements. Nous nous sommes particulierement orientes dans trois voies: - echangeurs d'ions naturels a structure minerale (argile du type montmorillonite), - composes mineraux naturels traites pour leur conferer les proprietes d'echangeurs d'ions (charbons actives), - composes mineraux synthetiques (sels tres peu solubles, phosphate et hydroxyde de zirconium et de thorium). Dans ces etudes, nous nous sommes attaches a obtenir des produits stables en presence d'eau a haute temperature, tres insolubles et non

    Document available in extended abstract form only. The Paris Basin system covers approximately 200 000 km 2 and consists of 27 aquiferous and semipermeable (aquitard) hydrogeological units of Trias to Quaternary age that are intersected by 80 regional faults. The Meuse/Haute-Marne site is located in the eastern part of the Paris Basin and covers approximately 250 km 2 . Within the sector, the Callovo-Oxfordian clay formation is a potential host for the French high and intermediate level and long lived radioactive waste. It is located at a mean depth of 500 m and has a minimum thickness of 130 m and very low hydraulic conductivity, on the order of 10-14 m/s. The Callovo-Oxfordian is confined between the overlying Oxfordian aquifer and the underlying Dogger aquifer. Both the Oxfordian and Dogger are limestone aquifers characterized locally by macro-pores, regional faults that oriented along the N40 deg. E direction (the Gondrecourt and Joinville faults) and the N150 deg. E direction (the Marne and Poissons faults), as well as diffuse fracture zones located south west of the Meuse/Haute-Marne Repository site. To support site investigation of the Meuse/Haute-Marne underground repository, a single continuum multi-scale hydrogeological model of the Paris Basin and the Meuse/Haute-Marne sector has been developed. The model represents 27 hydrogeological units at the scale of the Paris Basin, and it is refined at the scale of the sector to represent 27 different layers that range in age from the Trias to the Portlandian. The model has been calibrated to observed hydraulic heads by varying the hydraulic conductivity of the individual layers, using a single continuum approach. To investigate the impact of treating the two confining layers for the clay formation, the Oxfordian and Dogger aquifers, as single continua with equivalent hydraulic properties for the combined fracture and matrix system, additional simulations have been conducted with either a dual continuum or

    Interviews are a common method of data collection in nursing research. They are frequently used alone in a qualitative study or combined with other data collection methods in mixed or multi-method research. Semi-structured interviews, where the researcher has some predefined questions or topics but then probes further as the participant responds, can produce powerful data that provide insights into the participants' experiences, perceptions or opinions.

    Document available in extended abstract form only. A clay-stone formation of Callovo-Oxfordian age is found throughout the multilayered sedimentary fill of the Paris Basin. It is considered as a potential host rock for France's high and intermediate-level long-lived radioactive waste. The Callovo-Oxfordian layer is located between an overlying limestone of Oxfordian age and an underlying limestone of Dogger age.. The Meuse/Haute-Marne sector area is located in the East of France, the area includes the Bure investigation site and a domain referred to as the 'transposition zone' selected as a suitable location for France's high- and intermediate-level long-lived radioactive waste The objective of the study was to estimate how the groundwater flow in the Meuse/Haute- Marne aquifer system will change because of the geomorphologic evolution over the next 1 million of years. The future groundwater flows and the future evolution of the vertical hydraulic gradient in the transposition zone are of importance in the performance assessment and the safety analysis of a future repository for radioactive waste. The study is based on numerical modelling and the established model covers the whole of the Paris basin. The studied time period corresponds to 1 million years into the future. The initial geometry of geological layers as well as the conductivity and the porosity of the layers are input data to model, and defined by the single-continuum multi-scale hydrogeological model of the Paris Basin and the Meuse/Haute-Marne Sector area as developed by Andra. A description of the transient geomorphologic evolution was used as input data to the groundwater flow modelling. The description include: (i) The deformation of the geological layers as a result of a non-symmetric tectonic uplift of the Paris basin and (ii) The movement of the topography because of mechanical erosion along valleys, chemical erosion along plateaus and sedimentation along valleys.

    ). Eine der Anwendungen des Thermalwassers ist die Exposition der Patienten in einer 450 1 fassenden Wanne (Best'sche Wanne) mit anschliessender Ruhephase. Um die Hypothese, dass die Zerfallsprodukte des Radons eine wichtige Rolle bei der therapeutischen Wirkung spielen, zu ueberpruefen, sollte das Anlagerungsverhalten der Rn-Folgeprodukte untersucht werden. Nach einem Aufenthalt der Testpersonen von 20 Minuten in der Wanne wurde der Aktivitaetsverlauf an verschiedenen Punkten des Koerpers (Unterarme, Bauch, Unterschenkel) alpha-spektrometrisch gemessen. Aus den Spektren und den Zerfallskurven koennen die Aktivitaeten der einzelnen Folgeprodukte {sup 218}Po, {sup 214}Pb und {sup 214}Bi/{sup 214}Po unterschieden werden. Um den zeitlichen Verlauf der Zerfallsproduktanlagerung zu untersuchen, wurde eine Versuchsperson dem Wasser jeweils fuer 10, 20, 30, 40 und 60 Minuten ausgesetzt; danach wurde wieder der Aktivitaetsverlauf ueber 30 Minuten aufgezeichnet. Die Messungen zeigten, dass sich die Aktivitaeten der einzelnen Zerfallsprodukte auf der Haut stark unterscheiden. Einerseits scheint die Verteilung am Koerper keineswegs homogen zu sein, andererseits konnten individuelle Unterschiede zwischen den einzelnen Person beobachtet werden. So schwankten die Mittelwerte der Aktivitaeten auf der Haut zwischen 1,2 Bq/cm{sup 2} und 4,1 Bq/cm{sup 2}. Die Exposition und Messung von Kupfer- und PVC-Platten bestaetigten fruehere Ergebnisse, nach denen sich Radonzerfallsprodukte auf unbelebten Flaechen weniger stark anlagern als auf belebten. Aus der Tatsache, dass die Zerfallsprodaktivitaeten auf der Haut bemerkenswert hoch sind, erscheint ein moeglicher Zusammenhang mit der Heilwirkung seht wahrscheinlich. (orig.)

    Introduction Des différences épidémiologiques, étiologique voire pronostique des hémorragies digestives hautes (HDH) entre les deux sexes opposés ont été cité par différentes études. Méthodes Nous avons essayé de déceler ces différences à travers une analyse rétrospective nichée sur une étude prospective sur les hémorragies digestives hautes ayant inclus 945 patients. Résultats Six cents trente-sept patients étaient des hommes (67,4% Vs 32,6%). Un antécédent d'HDH était trouvé chez 24,2% des cas sans différence significative entre les deux sexes. L'âge de survenue de l'hémorragie était plus élevé chez les femmes que chez les hommes : 51,5 ans ± 18,8 Vs 47,8 ans ± 18,3 (p : 0,003). Les étiologies de l'HDH étaient différentes entre les deux sexes. Alors que l'hémorragie liée à l'HTP était la première cause chez la femme (38 % Vs 23,5 % chez l'homme, psexe masculin contre 35,4 % des patientes avec un p = 0,03. Le taux de récidive et de décès global étaient de 7,5 % et de 5,7 % des cas respectivement, sans différence significative entre les deux sexes. Conclusion L'étude trouve un profil épidémiologique, clinique et étiologique différent selon le sexe des patients. PMID:23077715

    Following the excellent results obtained on the industrial coating of radioactive sludges, the possibility of solidifying also the evaporation concentrates with bitumen has been considered. For high activity concentrates, the use of bitumen is however limited by two main parameters: temperature resistance, irradiation resistance. By making use of the characteristics of a blown bitumen, it has been possible to design a high activity coating pilot plant treating concentrations of several tens of curies per litre. This plant will make use of a screw-type extrusion machine capable of coating treated concentrates at a rate of 20 l/hr. Before being coated, the concentrates will be subjected to a coprecipitation treatment designed to make the radioelements insoluble. This installation will make possible, apart from technological studies, laboratory experiments on the coated material (measurements on self-heating, on electrical charges, on radiolytic gases, and also lixiviation tests. It is at present believed, on the basis of available data, that it is possible to coat concentrates having an activity of 20 Ci/l at a price of 1840 F per cubic metre. (authors) [French] A la suite des excellents resultats obtenus pour l'enrobage industriel des boues radioactives, il a ete envisage de solidifier egalement les concentrats d'evaporation par le bitume. Pour les concentrats de haute activite, l'emploi du bitume est cependant limite par deux parametres essentiels: tenue a la temperature, tenue a l'irradiation. Grace aux caracteristiques d'un bitume souffle, il a ete possible de concevoir une installation pilote d'enrobage haute activite contenant plusieurs dizaines de curies par litre. Cette installation utilisera une machine du type extrudeuse a vis qui peut enrober 20 l/h de concentrats traites. Avant leur enrobage, les concentrats subiront un traitement de coprecipitation destine a insolubiliser les radioelements. En dehors des etudes technologiques, cette installation

    This work deals with the environmental and technical evaluation of the implementation of municipal waste management schemes for the city of Ouagadougou (Burkina Faso). The context is the one of a low income developing country with no pollution regulation and with a governmental will of decentralization of the waste management activity towards the city authorities with the participation of the private and associative sectors. A status of the existing system and of the characteristics of the municipal wastes is made first (grain size, calorific value, humidity). On the basis of the life cycle analysis (LCA) methodology, 4 management systems are proposed and analyzed: complete disposal, sorting and composting of the fermentescible part, sorting and incineration of the combustible part, and composting and incineration. An inventory analysis and a qualitative impact analysis of each of these systems is performed. An experiment of incineration of these wastes has been carried out from a mixture of wood, cardboard and plastics representative of the combustible fraction of the Ouagadougou municipal wastes. A counterflow fixed bed reactor has been used to analyze the influence of the air excess on the combustion process and on the abatement of pollutant emissions (NO and CO). Finally, a technical-economical analysis of the management systems is presented with respect to their socio-economical implementation possibilities. (J.S.)

    The 1836/93 EMAS is the European regulation on environmental management and auditing scheme. Its aim is to answer the precise requirements of a standard for the management of the environmental impacts of industrial activities. The ISO 14001 standard defines the requirements of an environmental management policy at the international scale. The aim of this study is to make a statement of the enforcement of the ISO 14001 and EMAS environmental management systems in France in terms of results and with respect to the help provided by public authorities. The following aspects are analyzed successively: the aim of the study (context, global goal, hypotheses, cost-benefit analysis, qualitative appraisal); the methodological aspects (selection of sites, sectoral distribution, geographical, legal and financial aspects, data collection, analysis and synthesis); the motivation of companies (sectoral analysis, business aspects, reduction of operation costs, personnel motivation); the objectives of the environmental management system (conformability analysis, environmental goals, effluents, soil pollution, energy and water conservation, wastes, consumption of raw materials, noise and other pollutants); economical aspects (cost, personnel training, audits, benefits, minimization of environmental impacts, reduction of energy, water and materials consumption); cost-benefit evaluation; environmental efficiency of the environmental management system; attitude of other companies; comparison with other European countries; synthesis and proposals.

    Full Text Available Background. No in-depth qualitative research exists about the effects of therapeutic massage with children hospitalized to undergo hematopoietic cell transplantation (HCT. The objective of this study is to describe parent caregivers' experience of the effects of massage/acupressure for their children undergoing HCT. Methods. We conducted a qualitative analysis of open-ended interviews with 15 parents of children in the intervention arm of a massage/acupressure trial. Children received both practitioner and parent-provided massage/acupressure. Results. Parents reported that their child experienced relief from pain and nausea, relaxation, and greater ease falling asleep. They also reported increased caregiver competence and closeness with their child as a result of learning and performing massage/acupressure. Parents supported a semistandardized massage protocol. Conclusion. Massage/acupressure may support symptom relief and promote relaxation and sleep among pediatric HCT patients if administered with attention to individual patients' needs and hospital routines and may relieve stress among parents, improve caregiver competence, and enhance the sense of connection between parent and child.

L'observation au MEB des éprouvettes de traction indique que, dans la gamme de température observée pour laquelle il y a fragilisation, on a mouillage intergranulaire des joints de grains de l'acier à l'interface acier/revêtement par des films de Zn. La corrélation entre mouillage intergranulaire thermiquement activé d'une part, et propagation de fissure lors du chargement d'autre part, est discutée. This study deals with liquid zinc embrittlement for electro-galvanized steel. Mechanical characterization by high temperature tensile tests shows a drastic loss of ductility between 700 ∘C and 950 ∘C. SEM investigations show that steel grain boundaries under the steel/coating interface are penetrated by a liquid Zn channel, only in the temperature range of embrittlement. A correlation can be drawn between i thermal activated-grain boundary wetting and ii crack propagation in presence of external stress.

    Industrial emissions, deteriorating or improperly removed lead paint, and the use of lead additives in fuel have left a substantial burden of heavy metals, such as lead, in urban soils. Much of this lead remains near the surface where it has the potential to impact human health. Exposure to lead, especially in children, can have lasting impacts on neurological development and academic achievement. Urban gardening, in particular, is an activity that could result in increased exposure to soil lead for many unsuspecting gardeners. During the summer of 2012, more than 1,061 surface soil samples were collected from an approximately 1.25 acre urban community garden in Terre Haute, Indiana. Samples were collected to evaluate the spatial distribution of lead across the community garden on the plot level. The results highlight the variability that can be seen within small areas of a former residential property, for example lead concentrations that are low (garden plot as concentrations that are considered high (>600 ppm). Based on the results of this work, several areas of concern were identified and the community garden was reconfigured to reduce potential lead exposure to gardeners and the local community.

    In the process of treating irradiated uranium, plutonium can be separated from the majority of the fission products and from the uranium by TBP extraction cycles. The high purity necessary for metallurgical and nuclear physics experiments led us to consider more elaborate purification processes, and a specially adapted method of fluoride preparation. The first part of the paper describes purification cycles of plutonium in solution on ion exchange resins, and the results are given. The second part contains the description and results of the fluoride preparation method.

    From the middle to the end of the twentieth century, several thousands tons of uranium have been extracted from the ground of the French department of Haute-Vienne. These activities have not been without any environmental consequences. Water is an environmental compartment particularly vulnerable because several polluting factors may release radionuclides from 238 U chain a long time after the end of the mining activities. It has been shown that water used for drinking water fabrication for the City of Limoges, 140 000 inhabitants, and for a group of 22 communes with 20 000 inhabitants and leisure water of Saint-Pardoux lake have activities which are unusually high. A health risk quantitative assessment has been carried out. The results show for radiological risk that 226 Ra is, in the most realistic hypothesis, the main responsible for the annual effective dose; moreover, the annual effective dose are lower than the radioprotection standards and the WHO's recommendations of 0.1 mSv per year in drinking water. The results also show that it would not be pertinent to carry out an epidemiological study because of a lack of statistical power. (author)

    The objective of our study was to determine the trace metal accumulation rates in the Misten bog, Hautes-Fagnes, Belgium, and assess these in relation to established histories of atmospheric emissions from anthropogenic sources. To address these aims we analyzed trace metals and metalloids (Pb, Cu, Ni, As, Sb, Cr, Co, V, Cd and Zn), as well as Pb isotopes, using XRF, Q-ICP-MS and MC-ICP-MS, respectively in two 40-cm peat sections, spanning the last 600 yr. The temporal increase of metal fluxes from the inception of the Industrial Revolution to the present varies by a factor of 5-50, with peak values found between AD 1930 and 1990. A cluster analysis combined with Pb isotopic composition allows the identification of the main sources of Pb and by inference of the other metals, which indicates that coal consumption and metallurgical activities were the predominant sources of pollution during the last 600 years.

    In this article, I explore the meaning of experiments in early twentieth century psychology, focusing on the qualitative experimental methodology of psychologist Frederic BARTLETT. I begin by contextualizing BARTLETT's experiments within the continental research tradition of his time, which...... was in a state of transition from a focus on elements (the concern of psychophysics) to a focus on wholes (the concern of Gestalt psychology). The defining feature of BARTLETT's early experiments is his holistic treatment of human responses, in which the basic unit of analysis is the active person relating...... to some material within the constraints of a social and material context. This manifests itself in a number of methodological principles that contrast with contemporary understandings of experimentation in psychology. The contrast is further explored by reviewing the history of "replications...

  15. Qualitative quark confinement

    1976-01-01

    The infrared limit in asymptotically free non-abelian gauge theories using recently developed non-perturbative methods which allow derivation of zero momentum theorems for Green's functions and vertices is described. These low-energy theorems are compared to the infrared behavior predicted from the renormalization group equation when the existence of an infrared fixed point is assumed. A set of objects is exhibited whose low energy theorems violate the scaling behavior predicted by the renormalization group. This shows that the assumed fixed point cannot exist and that in the Landau gauge the effective charge becomes infinite in the infrared. Qualitatively this implies that as an attempt is made to separate elementary quanta the interaction between the quanta becomes arbitrarily strong. This indicates at least that the theories studied are capable of color confinement. Results are true only for theories with large numbers of quarks. This opens the possibility that large numbers of quarks are actually necessary for confinement

    Qualitative nurse researchers are required to make deliberate and sometimes complex methodological decisions about their work. Methodology in qualitative research is a comprehensive approach in which theory (ideas) and method (doing) are brought into close alignment. It can be difficult, at times, to understand the concept of methodology. The purpose of this research column is to: (1) define qualitative methodology; (2) illuminate the relationship between epistemology, ontology and methodology; (3) explicate the connection between theory and method in qualitative research design; and 4) highlight relevant examples of methodological decisions made within cardiovascular nursing research. Although there is no "one set way" to do qualitative research, all qualitative researchers should account for the choices they make throughout the research process and articulate their methodological decision-making along the way.

    We tested a theory that mind mapping could be used as a tool in qualitative research to transcribe and analyse an interview. We compared results derived from mind mapping with those from interpretive phenomenological analysis by examining patients' and carers' perceptions of a new nurse-led service. Mind mapping could be used to rapidly analyse simple qualitative audio-recorded interviews. More research is needed to establish the extent to which mind mapping can assist qualitative researchers.

    After some initial trepidation, I was excited about teaching a graduate seminar in qualitative methods. It could hardly be a more interesting time. The publication of King, Keohane, and Verba’s Designing Social Inquiry reinvigorated interest in qualitative methods, and I wanted to design the course to profit from this emerging debate. Whereas KKV appealed to qualitative researchers to do their best to adopt quantitative methodological guidelines, I wanted to encourage students to think about ...

    Full Text Available The goal of this paper is to present tools which allow informal firms to improve their social and environmental performance and become sustainable enterprises. The paper first provides an overview of the informal economy and sustainable enterprises from the perspective of the International Labor Organization. The methodological part consists of a presentation of tools which can be used to facilitate the transition of informal businesses to formality. Tools are divided into two groups: Those which require the active participation of private partners, and others which are based on partnerships between public and private entities. Applications of tools from experiences in different developing countries and mainly from projects run by the International Labor Organization are presented and their achievements and limits discussed.The paper concludes that a more focused approach on the informal economy should be adopted if more positive results are to be achieved in terms of improved social and environmental performance of enterprises. In addition, it highlights that the impact of actions on informal firms should always be monitored and reported even when the focus of projects is not on the informal economy.L’objectif de cet article est de présenter les outils qui permettent aux entreprises informelles d’améliorer leurs performances sociales et environnementales afin de s’inscrire dans la durabilité. Cet article s’ouvre sur un aperçu de l’économie informelle et des entreprises durables du point de vue de l’Organisation Internationale du travail. Il se poursuit par une partie méthodologique qui consiste en une présentation des outils permettant d’aider les entreprises de passer de l’état informel à l’état formel. Ces outils se répartissent en deux groupes : ceux qui nécessitent la participation active de partenaires privés et ceux basés sur le partenariat entre entités publiques et privées.

    The new imperative in the health disciplines to be more methodologically inclusive has generated a growing interest in mixed research synthesis, or the integration of qualitative and quantitative research findings. Qualitative metasummary is a quantitatively oriented aggregation of qualitative findings originally developed to accommodate the distinctive features of qualitative surveys. Yet these findings are similar in form and mode of production to the descriptive findings researchers often present in addition to the results of bivariate and multivariable analyses. Qualitative metasummary, which includes the extraction, grouping, and formatting of findings, and the calculation of frequency and intensity effect sizes, can be used to produce mixed research syntheses and to conduct a posteriori analyses of the relationship between reports and findings.

    Full Text Available Le «District Spécial» de Bogotá est doublement singulier: par son statut administratif, promulgué sous État de Siège en 1954, qui en fait une entité territoriale à part, à mi-chemin entre la commune et le département, et par l’immense zone rurale qu’il inclue au sud de la ville, le Haut-Sumapaz, une région difficile d’accès, très peu peuplée et totalement sous-intégrée à la capitale colombienne. L’annexion du Haut-Sumapaz au District de Bogotá répond à des impératifs militaires, liés au particularisme géopolitique de la région.

    Since their discovery in the years 1986/87, the high critical temperature superconductors have reached nowadays performances interesting enough to conceive passive magnetic bearings and suspensions which would combined permanent magnets and naturally stable superconducting pellets. After underlining the principal factors that affect the superconductormagnet interaction, different experimental results are given about vertical and axial forces with some stiffness values. The magnetization curve of a superconductor help to understand the hysteretic behavior of the force as a function of the distance between superconductor and magnet. So called simple and hybrid structures of superconducting magnetic suspension are presented. Finally simple numerical simulations allow to draw some interesting conclusions about both geometry and best fitting structure of permanent magnets. Depuis leur découverte dans les années 1986/87, les supraconducteurs à haute température critique ont désormais atteint des performances intéressantes et rendent envisageables des paliers et suspensions magnétiques passives associant aimants permanents et pastilles supraconductrices naturellement stables. Après avoir indiqué les termes importants influençant l'interaction supraconducteur - aimant, différents relevés expérimentaux sont donnés pour les forces verticales et transversales avec quelques valeurs de raideurs. La courbe d'aimantation d'un supraconducteur permet de comprendre le comportement hystérétique de la force en fonction de la distance supraconducteur-aimant. Les structures dites simple et hybride des suspensions magnétiques supraconductrices sont présentées. Enfin quelques simulations numériques simples permettent de dégager quelques conclusions intéressantes quant aux géométries respectives et aux structures d'aimants permanents les mieux adaptées.

  7. Scientific investigation in deep wells for nuclear waste disposal studies at the Meuse/Haute Marne underground research laboratory, Northeastern France

    Science.gov (United States)

    Delay, Jacques; Rebours, Hervé; Vinsot, Agnès; Robin, Pierre

    Andra, the French National Radioactive Waste Management Agency, is constructing an underground test facility to study the feasibility of a radioactive waste disposal in the Jurassic-age Callovo-Oxfordian argillites. This paper describes the processes, the methods and results of a scientific characterization program carried out from the surface via deep boreholes with the aim to build a research facility for radioactive waste disposal. In particular this paper shows the evolution of the drilling programs and the borehole set up due to the refinement of the scientific objectives from 1994 to 2004. The pre-investigation phase on the Meuse/Haute-Marne site started in 1994. It consisted in drilling seven scientific boreholes. This phase, completed in 1996, led to the first regional geological cross-section showing the main geometrical characteristics of the host rock. Investigations on the laboratory site prior to the sinking of two shafts started in November 1999. The sinking of the shafts started in September 2000 with the auxiliary shaft completed in October 2004. The experimental gallery, at a depth of 445 m in the main shaft, was in operation by end 2004. During the construction of the laboratory, two major scientific programs were initiated to improve the existing knowledge of the regional hydrogeological characteristics and to accelerate the process of data acquisition on the shales. The aim of the 2003 hydrogeological drilling program was to determine, at regional scale, the properties of groundwater transport and to sample the water in the Oxfordian and Dogger limestones. The 2003-2004 programs consisted in drilling nine deep boreholes, four of which were slanted, to achieve an accurate definition of the structural features.

    Full Text Available Les inégalités de revenu se font croissantes dans la plupart des pays avancés et la richesse se concentre davantage au sommet de la pyramide sociale. Les deux principaux courants de pensée, l’école institutionnaliste et l’école du marché, peinent à expliquer pourquoi la hausse des inégalités de revenus se concentre principalement dans le centile le plus fortuné. Partant de ce constat, un nouveau courant de pensée s’est plutôt concentré, à l’instigation entre autres d’Atkinson, Piketty et Saez, sur les statistiques fiscales des très hauts revenus, fortement sous-estimés dans les enquêtes par sondage. Cet article présente une synthèse critique de leurs hypothèses, de leur méthodologie et de leurs résultats.Income inequalities are increasing in most advanced countries and most of the wealth has become concentrated at the top of the social pyramid. Institutionalist and market-based theories, the two main schools of thought on the subject, struggle to explain why the rise in income inequality is mainly concentrated in the most fortunate percentile. Based on this observation, Atkinson, Piketty and Saez have opened a new field of study specifically on top incomes (severely underestimated in surveys, based on tax statistics. This article presents a critical overview of their assumptions, their methodology and results.

    A phenomenological model suited for the description of arbitrary two-body reactions at high energies is presented and applied to the analysis of {pi} - nucleon, K - nucleon, et K-bar - nucleon scattering.The idea is that the Regge-pole model does not take into account the whole content of the unitarity relation and has to be modified, as is currently done in one-particle exchange models, so that it may include absorptive corrections.In terms of a rather economical set of free parameters,we obtain a satisfactory agreement with all available data, including the recent evidence for a nonvanishing polarization in {pi}{sup -} p {pi}{sup 0} n reaction. We then reinterpret our parametrization of the amplitudes in terms of poles and branch points in the complex angular-momentum plane for the crossed channel. (author) [French] Un modele phenomenologique adapte a la description des reactions a deux corps a haute energie est presente et applique a l'analyse des diffusions {pi} - nucleon, K - nucleon, et K-bar - nucleon. L'idee essentielle est que le modele d'echange de poles de Regge ne tient pas compte du contenu total de la relation d'unitarite et doit etre modifie, comme cela a ete propose dans le cas de l'echange de particules, de facon a tenir compte de corrections de type absortif. Au moyen d'un ensemble relativement economique de parametres libres nous obtenons un accord satisfaisant avec tous les resultats disponibles, y compris l'existence recemment mise en evidence d'une polarisation non nulle dans la reaction {pi}{sup -} p {pi}{sup 0} n. Nous interpretons notre fa n d'ecrire les amplitudes au moyen de poles et de points de branchement dans le plan complexe du moment angulaire pour la voie croisee. (auteur)

    Full Text Available The daily oil production from the Schoonebeek Oilfield amounts to some 1400 m3 /d, of which ca. 65% is produced from a high pressure (85 bar steam injection project. This project was started in 1981 and originally consisted of 7 structurally downdip/middip steam injectors. However, following the initially somewhat disappointing project performance, steam injection was moved to 4 middip/ updip injectors in 1984. This change in the location of the steam injectors, together with an increase in the level of surveillance and a more pragmatic reservoir management policy, has resulted in improved project performance. The ultimate extra oil/steam ratio for the total project is now expected to be 0. 7 m3 oil/ton of steam injected. La production de pétrole du gisement de Schoonebeek est d'environ 1400 m3/jour, dont près de 65% sont obtenus par injection de vapeur à haute pression (85 bar. Ce projet lancé en 1981 comportait initialement 7 injecteurs de vapeur orientés vers l'aval-pendage. En raison de performances décevantes, l'injection de vapeur a été transférée en 1984 sur 4 injecteurs travaillant vers l'amont-pendage. Ce changement de position des injecteurs, accompagné d'une surveillance renforcée et d'une politique de gestion du gisement plus pragmatique, a donné des résultats favorables. On pense que le rapport pétrole/vapeur pour l'ensemble du projet devrait être en dernière analyse de 0,7 m3 de pétrole par tonne de vapeur injectée.

    Document available in extended abstract form only. The Meuse/Haute-Marne site covers an area of approximately 250 km 2 and it is located in the eastern part of the Paris Basin (200 000 km 2 ). The Callovo-Oxfordian clay formation, which is found throughout the Paris Basin, is considered as a potential host rock for France's high- and intermediate-level long-lived radioactive waste. At the project site (the Sector area), the Callovo-Oxfordian Formation is encountered at a depth of roughly 500 m, with a minimum thickness of approximately 130 m and a very low (on the order of 10-14 m/s) hydraulic conductivity. The Callovo-Oxfordian layer is confined between an overlying limestone aquifer of Jurassic-Oxfordian age and an underlying limestone of Jurassic-Dogger age. Analyses of the possible transfer of solute from the host formation into the surrounding aquifer system during the next million of years are required for safety calculations. These analyses are based on estimates of the future geomorphologic and climatic evolution of the area and on calculations of the future evolution of groundwater flow and solute transport behaviour in the units surrounding the Callovo-Oxfordian clay. To support the analyses of the future regional and local hydrogeological evolutions, a single-continuum multi-scale hydrogeological model of the Paris Basin and the Meuse/Haute-Marne sector has been developed. The model represents 27 hydrogeological units at the scale of the Paris Basin, and it is refined at the scale of the studied domain (the Sector area) to represent 27 different layers that range in age from Trias to Jurassic-Portlandian. The model has been calibrated to observed hydraulic heads. The present work deals with permafrost generation and retreat during a glacial cycle and the resulting consequences on the groundwater flow patterns within the Meuse/Haute-Marne aquifer system. The conceptual model of permafrost generation is that the pore water is frozen to create ice

    The first part of this research thesis addresses the theory of high frequency discharge in gases under low pressures, and first proposes a calculation of the distribution function for electrons present within the gas. The author then studies the evolution of electron density within a discharge tube by assigning the governing role in electron multiplication to the secondary emission of tube walls. The second part proposes a detailed description of a source operating at 96.5 Mc/s, a discussion of measurements performed on this source, and the search for a theoretical explanation of some of its properties. The author then briefly analyses various existing types of high frequency sources, and finally discusses their use in corpuscular microscopy and in particle accelerators [French] La presente these comprend deux parties. La premiere est consacree a la theorie de la decharge haute frequence dans les gaz aux faibles pressions et comporte tout d'abord le calcul de la fonction de distribution des electrons presents au sein du gaz. Nous etudions ensuite l'evolution de la densite electronique a l'interieur d'un tube a decharge en attribuant, a l'emission secondaire des parois de ce dernier, le role essentiel dans la multiplicalion des electrons. Nous obtenons ainsi les conditions d'amorcage. Tout au long de cette etude, on doit distinguer soigneusement le cas ou le libre parcours moyen des electrons dans le gaz est inferieur aux dimensions de l'enceinte et le cas ou il leur est superieur. La deuxieme partie comprend la description detaillee d'une source fonctionnant sur 96.5 Mc/s, l'expose des mesures effectuees sur celle-ci et la recherche d'une explication theorique de certaines de ses proprietes. Nous faisons ensuite une breve analyse des divers types de sources d'ions haute frequence existant a l'heure actuelle et nous terminons en traitant de leur utilisation en microscopie corpusculaire et dans les accelerateurs de particules.

    Abstract Experimental philosophy brings empirical methods to philosophy. These methods are used to probe how people think about philosophically interesting things such as knowledge, morality, and freedom. This paper explores the contribution that qualitative methods have to make in this enterprise. I argue that qualitative methods have the potential to make a much greater contribution than they have so far. Along the way, I acknowledge a few types of resistance that proponents of qualitative methods in experimental philosophy might encounter, and provide reasons to think they are ill-founded.

    1998-02-01

    Qualitative methods appear increasingly in vogue in health services research (HSR). Such research, however, has utilized, often uncritically, a 'cookbook' of methods for data collection, and common-sense principles for data analysis. This paper argues that qualitative HSR benefits from recognizing and drawing upon theoretical principles underlying qualitative data collection and analysis. A distinction is drawn between problem-orientated and theory-orientated research, in order to illustrate how problem-orientated research would benefit from the introduction of theoretical perspectives in order to develop the knowledge base of health services research.

    Full Text Available Landscapes Prospective Modeling of the landscapes of the Haut Sassandra Classified Forest (Côte d'Ivoire After the End of The Conflicts. It has been demonstrated that armed conflicts cause biodiversity's degradation, especially in its ecosystemic and specific dimensions. The Haut Sassandra Classified Forest is an interesting case study for this kind of process. Indeed, during the conflicts, a massive migrants infiltration caused a forest cover decline and a plant diversity loss. We created a multi-agent system able to simulate the actors' movements and behaviors. The social simulation generates scenario in the form of clearing maps in classified forest. This model was first conceived as a retro-prospective model in order to test hypotheses on the social dynamics underlying this process, after having worked on its accuracy by confronting reality. This model being validated, the aim of this paper is to present a prospective modeling to illustrate, in terms of forest cover's conservation, the possible consequences of different demographic and political scenarios. Across a geoprospective logic, two scenarios are mentioned such as the continuation of conflict period trends and a proposition of ecological restoration.

    Full Text Available Ce papier traite de la modélisation de joints collés pour les structures soumises à des sollicitations de type crash. Cette nouvelle modélisation basée sur un élément cohésif tient compte du comportement viscoplastique, de l'endommagement ainsi que de la rupture de l'adhésive. Sensible à la vitesse de déformation l'identification du critère de rupture nécessite une base expérimentale allant jusqu'à de très hautes vitesses de déformations. Un nouveau dispositif d'essais a donc été mis en place sur les barres de Hopkinson afin de solliciter des assemblages à haute vitesse et sous différents angles de chargement. This paper deals with the modeling of bonded joints for structures subjected to dynamic crash loading. This new model based on a cohesive element takes into account the viscoelastic behavior, the damage and the failure of the adhesive. Due to the strain rate sensitivity, the identification of failure criterion requires experimental tests, up to very high strain rates. A new testing device has then been set up on the Hopkinson bar in order to load the assemblies with high strain rates and with different angles.

    Full Text Available The flipped classroom instructional model has emerged as an alternative to conventional lecture-based teaching that has dominated higher education for decades. In 2013, a cohort of graduate-level public health students participated in a flipped environmental and occupational health course. We present the design, implementation, and evaluation of this course. Using data collected from a post-course survey, focus group sessions, and classroom observation, we examine student perceptions of the flipped classroom instructional model and synthesize lessons learned from flipping the classroom more broadly. Post-course survey data indicate that students had generally positive perceptions towards the flipped classroom instructional model. Four major themes emerged from the focus group data in relation to perceptions of the flipped classroom: knowledge application, content delivery, innovation, and connecting the online and in-class components. These results are promising and suggest that this approach warrants further consideration and research. Le modèle pédagogique de la classe inversée a émergé comme solution de rechange à l’enseignement traditionnel par cours magistraux qui a dominé l’éducation supérieure pendant des décennies.

    Des mesures de resistance longitudinale et de resistance de Hall en champ magnetique intense transverse (perpendiculaire aux plans CuO2) ont ete effectuees au sein de monocristaux de YBa2Cu3Oy (YBCO) demacles, ordonnes et de grande purete, afin d'etudier l'etat fondamental des supraconducteurs a haute Tc dans le regime sous-dope. Cette etude a ete realisee en fonction du dopage et de l'orientation du courant d'excitation J par rapport a l'axe orthorhombique b de la structure cristalline. Les mesures en champ magnetique intense revelent par suppression de la supraconductivite des oscillations magnetiques des resistances longitudinale et de Hall dans YBa2Cu 3O6.51 et YBa2Cu4O8. La conformite du comportement de ces oscillations quantiques au formalisme de Lifshitz-Kosevich, apporte la preuve de l'existence d'une surface de Fermi fermee a caractere quasi-2D, abritant des quasiparticules coherentes respectant la statistique de Fermi-Dirac, dans la phase pseudogap d'YBCO. La faible frequence des oscillations quantiques, combinee avec l'etude de la partie monotone de la resistance de Hall en fonction de la temperature indique que la surface de Fermi d'YBCO sous-dope comprend une petite poche de Fermi occupee par des porteurs de charge negative. Cette particularite de la surface de Fermi dans le regime sous-dope incompatible avec les calculs de structure de bande est en fort contraste avec la structure electronique presente dans le regime surdope. Cette observation implique ainsi l'existence d'un point critique quantique dans le diagramme de phase d'YBCO, au voisinage duquel la surface de Fermi doit subir une reconstruction induite par l'etablissement d'une brisure de la symetrie de translation du reseau cristallin sous-jacent. Enfin, l'etude en fonction du dopage de la resistance de Hall et de la resistance longitudinale en champ magnetique intense suggere qu'un ordre du type onde de densite (DW) est responsable de la reconstruction de la surface de Fermi.

    Potential wetland extents were estimated for a 14-mile reach of the Wabash River near Terre Haute, Indiana. This pilot study was completed by the U.S. Geological Survey in cooperation with the U.S. Department of Agriculture, Natural Resources Conservation Service (NRCS). The study showed that potential wetland extents can be estimated by analyzing streamflow statistics with the available streamgage data, calculating the approximate water-surface elevation along the river, and generating maps by use of flood-inundation mapping techniques. Planning successful restorations for Wetland Reserve Program (WRP) easements requires a determination of areas that show evidence of being in a zone prone to sustained or frequent flooding. Zone determinations of this type are used by WRP planners to define the actively inundated area and make decisions on restoration-practice installation. According to WRP planning guidelines, a site needs to show evidence of being in an "inundation zone" that is prone to sustained or frequent flooding for a period of 7 consecutive days at least once every 2 years on average in order to meet the planning criteria for determining a wetland for a restoration in agricultural land. By calculating the annual highest 7-consecutive-day mean discharge with a 2-year recurrence interval (7MQ2) at a streamgage on the basis of available streamflow data, one can determine the water-surface elevation corresponding to the calculated flow that defines the estimated inundation zone along the river. By using the estimated water-surface elevation ("inundation elevation") along the river, an approximate extent of potential wetland for a restoration in agricultural land can be mapped. As part of the pilot study, a set of maps representing the estimated potential wetland extents was generated in a geographic information system (GIS) application by combining (1) a digital water-surface plane representing the surface of inundation elevation that sloped in the downstream

    Full Text Available Les canyons de Trévans sont incisés dans des unités calcaires jurassiques, dans la zone frontale subalpine, proche du piémont de Valensole. Ces reliefs sont en rapport avec les phases néotectoniques. Ce secteur fait principalement partie de la forêt domaniale du Montdenier, avec des écosystèmes montagnards et supra-méditerranéens, bois de hêtres et de chênes pubescents, large extension des brousses et d'importants reboisements en pins noirs. Les hautes surfaces conservent des traces d'un ancien aplanissement et des sols résiduels paléokarstiques. Sur les pentes, sous des escarpements démembrés, les éboulis et convois de blocs témoignent des processus périglaciaires hérités et, localement, des évènements séismiques. De nombreux processus dynamiques s'observent dans les canyons : éboulements provenant des parois affectées des effets de détente, coups de gouge et marmites de géant dans leur fond excavé par les écoulements turbulents dans les cascades… et le Pont de Tuf.The canyon system of Trevans has cut the blocks of the jurassic limestones, in subalpine over thrust front, near the Valensole piedmont. These landforms are in relationship with the neotectonic movements. This area belongs to the State Forest of Montdenier, woodland of various mountain and supra-mediterranean ecosystems, with beeches and white oaks Quercus pubescens, large extent of bush and important reforestation in black pines (Pinus nigra. The high surfaces preserve some relics of the old planation and paleokarstic forms and residual soils. On the slopes, under the break-up escarpments, the screes and landslides give the part of the periglacial processes and, locally, of the seismic events. Numerous dynamic processes occur in the canyons: rock-slides, in relationship with open fractures, scallops and pot-holes in the bottom excavated by the turbulent flows in the waterfalls of the creeks and, only case, a travertine bridge.

  13. Etude de la performance des radars hautes-frequences CODAR et WERA pour la mesure des courants marins en presence partielle de glace de mer

    Les radars hautes-frequences (RHF) mesurent les courants marins de surface avec une portee pouvant atteindre 200 kilometres et une resolution de l'ordre du kilometre. Cette etude a pour but de caracteriser la performance des RHF, en terme de couverture spatiale, pour la mesure des courants de surface en presence partielle de glace de mer. Pour ce faire, les mesures des courants de deux radars de type CODAR sur la rive sud de l'estuaire maritime du Saint-Laurent, et d'un radar de type WERA sur la rive nord, prises pendant l'hiver 2013, ont ete utilisees. Dans un premier temps, l'aire moyenne journaliere de la zone ou les courants sont mesures par chaque radar a ete comparee a l'energie des vagues de Bragg calculee a partir des donnees brutes d'acceleration fournies par une bouee mouillee dans la zone couverte par les radars. La couverture des CODARs est dependante de la densite d'energie de Bragg, alors que la couverture du WERA y est pratiquement insensible. Un modele de fetch appele GENER a ete force par la vitesse du vent predite par le modele GEM d'Environnement Canada pour estimer la hauteur significative ainsi que la periode modale des vagues. A partir de ces parametres, la densite d'energie des vagues de Bragg a ete evaluee pendant l'hiver a l'aide du spectre theorique de Bretschneider. Ces resultats permettent d'etablir la couverture normale de chaque radar en absence de glace de mer. La concentration de glace de mer, predite par le systeme canadien operationnel de prevision glace-ocean, a ete moyennee sur les differents fetchs du vent selon la direction moyenne journaliere des vagues predites par GENER. Dans un deuxieme temps, la relation entre le ratio des couvertures journalieres obtenues pendant l'hiver 2013 et des couvertures normales de chaque radar d'une part, et la concentration moyenne journaliere de glace de mer d'autre part, a ete etablie. Le ratio des couvertures decroit avec l'augmentation de la concentration de glace de mer pour les deux types

    Full Text Available Les introductions de Salmonidés ont été importantes au cours des 60 dernières années dans les lacs et ruisseaux d'altitude des Hautes-Pyrénées. Six espèces de Salmonidés ont été introduites dans des milieux qui, pour la plupart, étaient vierges de populations piscicoles : la truite commune (Salmo trutta L., la truite arc-en-ciel (Oncorhynchus mykiss Walbaum, l'omble de fontaine (Salvelinus fontinalis Mitchill, l'omble chevalier (Salvelinus alpinus L., le cristivomer (Salvelinus namaycush Walbaum et le splake (Salvelinus fontinalis x Salvelinus namaycush. Dans de très nombreux cas, ces introductions ont abouti à des acclimatations. En revanche, les naturalisations sont beaucoup plus rares. Seules les espèces lacustres (cristivomer et omble chevalier se sont naturalisées dans la majorité des lacs où elles ont été introduites. Les conditions de reproduction constituent le facteur clé permettant d'expliquer la naturalisation des espèces. En ruisseau, il faut y ajouter la compétition avec l'espèce indigène (la truite commune, la pression halieutique ainsi que les conditions hivernales très rigoureuses. Les incidences écologiques des introductions sur les populations de truites communes indigènes sont faibles. En revanche, elles ne sont pas négligeables pour les populations de batraciens. Cette politique d'introduction a largement participé au développement de l'halieutisme dans ces milieux d'altitude. En cela, les introductions ont parfaitement répondu aux objectifs halieutiques qu'on leur avait fixés. L'acquisition de connaissances sur l'ensemble de la chaîne pyrénéenne constitue aujourd'hui une étape incontournable pour une politique de gestion globale des introductions.

  16. Towards a Highly Efficient Meshfree Simulation of Non-Newtonian Free Surface Ice Flow: Application to the Haut Glacier d'Arolla

    Shcherbakov, V.; Ahlkrona, J.

    2016-12-01

    In this work we develop a highly efficient meshfree approach to ice sheet modeling. Traditionally mesh based methods such as finite element methods are employed to simulate glacier and ice sheet dynamics. These methods are mature and well developed. However, despite of numerous advantages these methods suffer from some drawbacks such as necessity to remesh the computational domain every time it changes its shape, which significantly complicates the implementation on moving domains, or a costly assembly procedure for nonlinear problems. We introduce a novel meshfree approach that frees us from all these issues. The approach is built upon a radial basis function (RBF) method that, thanks to its meshfree nature, allows for an efficient handling of moving margins and free ice surface. RBF methods are also accurate and easy to implement. Since the formulation is stated in strong form it allows for a substantial reduction of the computational cost associated with the linear system assembly inside the nonlinear solver. We implement a global RBF method that defines an approximation on the entire computational domain. This method exhibits high accuracy properties. However, it suffers from a disadvantage that the coefficient matrix is dense, and therefore the computational efficiency decreases. In order to overcome this issue we also implement a localized RBF method that rests upon a partition of unity approach to subdivide the domain into several smaller subdomains. The radial basis function partition of unity method (RBF-PUM) inherits high approximation characteristics form the global RBF method while resulting in a sparse system of equations, which essentially increases the computational efficiency. To demonstrate the usefulness of the RBF methods we model the velocity field of ice flow in the Haut Glacier d'Arolla. We assume that the flow is governed by the nonlinear Blatter-Pattyn equations. We test the methods for different basal conditions and for a free moving

    The alignment of grains in isostatically precompacted samples of prereacted Bi{1,8}Pb{0,4}Sr{2,0}Ca{2,2}Cu{3,0}O{10,3 + x} powder has been achieved by compressive plastic deformation under isostatic pressure at room temperature. Isostatic pressures were in the range 0.1 to 1 GPa and deformation rates were led up to 57 %. Prior to sintering, X-ray diffraction measurements corroborate an expected high- T_c phase purity of nearly 85 % and indicate that the as-deformed samples have been textured with the (c-axes parallel to the pressing direction whilst a.c. susceptibility measurements ascertain a high transition temperature around 107 K. Intergranular connection does not occur until sintering at 850 ^{circ}C for 80 h and measurements indicate then that the texture has been retained. Superconducting properties themselves show sensitivity to texture through anisotropy-related distinctive irreversibility lines. L'alignement de grains de poudre Bi{1,8}Pb{0,4}Sr{2,0}Ca{2,2}Cu{3,0}O{10,3 + x} préréagie a été réalisé par déformation plastique à température ambiante d'échantillons précompactés isostatiquement et comprimés sous pression isostatique, la gamme des pressions isostatiques allant de 0,1 à 1 GPa et les taux de déformation atteignant 57 %. Les mesures de diffraction de rayons X corroborent la pureté de phase à haute T_c proche de 85 % attendue et indiquent que les échantillons ainsi déformés ont été texturés avec les plans ab perpendiculaires à la direction de compression. Les mesures de susceptibilité alternative avèrent une température élevée de transition à environ 107 K mais la connexion intergranulaire n'est assurée qu'après un frittage à 850 ^{circ}C pendant 80 h dont on vérifie qu'il conserve la texture. Enfin, la sensibilité des propriétés supraconductrices à la texturation est évaluée par le biais de lignes d'irréversibilité distinctes en fonction de l'anisotropie.

    Document available in extended abstract form only. An integrated multi-scale hydrogeological conceptual model of the Paris basin and the Meuse/Haute-Marne sector was developed to study the groundwater flow and solute transport behaviour in the multi-layered aquifer system and around the Callovo-Oxfordian clay formation as potential host for the French high and intermediate level and long lived radioactive waste. The Paris basin system (200000 km 2 ) consists of 27 aquiferous and semi-permeable (aquitard) hydrogeological units from Trias to Quaternary affected by 80 regional faults. It produces boundary conditions to the refined aquifer system of the 250 km 2 Meuse/Haute-Marne site, which includes 27 layers from Trias to Portlandian. The Callovo-Oxfordian clay formation is located at a mean depth of 500 m, with a minimum thickness of 130 m and hydraulic conductivity values of the order of 10-14 m/s. The numerical steady-state flow solution is calculated on a finite element mesh of about 3 million 2-D and 3-D linear elements (GEOS-CHYN 2009). At the top surface, the mesh refinement (250 m to 50 m) is locally constrained by the fault lineaments and the river network. At depth, it takes into account the 10 m to 500 m throw of the faults and the vertical flow through semi-permeable units. Triangular elements are used to represent a top surface layer that includes the weathered part of the outcropping formations, and quadrangular elements allow for the representation of the faults planes at depth. The layers are discretized into 6-nodded wedge elements, while 4-nodded tetrahedrons and 5-nodded pyramids are used to handle the pinching and the outcrop of the layers. The flow boundary conditions and source-sink terms are: - Specified hydraulic heads (Dirichlet) along the rivers and elsewhere on the top surface inflow fluxes (Neumann) derived from hydrological balance (with a mean inflow of 240 mm/year). - Specified hydraulic heads (Dirichlet) at the Manche coast side. - No

    2014-07-01

    Full Text Available This article discusses questions that are relevant to the epistemology of qualitative research. In order to do so, the presumed dichotomy between qualitative and quantitative research is discussed and challenged. According to the author, the similarities between these methods are more relevant than its differences. Both methods strive to describe the social reality and thus have the same epistemological basis, even though they emphasize different questions. To shed light in such dichotomy, the author explores the origins of epistemology as a discipline and its philosophical character. Finally, the particularities and advantages of qualitative research are discussed, especially ethnography and field research, through an analysis of some of its main aspects for observing social reality: its focus on the point of view of the actor; the observation of the everyday world and the full and thick description.

    In this paper we focus on important considerations when planning and conducting qualitative interviews on sensitive topics. Drawing on experiences of conducting interviews with dementia caregivers, a framework of essential elements in qualitative interviewing was developed to emphasize study participants' needs while also providing guidance for researchers. Starting with a definition of sensitive research, the framework includes preparing for interviews, interacting with gatekeepers of vulnerable groups, planning for interview timing, and location, building relationships and conducting therapeutic interactions, protecting ethically vulnerable participants, and planning for disengagement. This framework has the potential to improve the effectiveness of sensitive interviewing with vulnerable groups. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

En Afrique de l'Ouest et Centrale, on assiste depuis les années 1970 à une sécheresse sans précédent, ainsi qu'à une grande variabilité spatiale et temporelle des pluies, caractéristique du domaine tropical. L'objectif de ce travail est de définir la variabilité spatio-temporelle des précipitations à l'échelle du haut-bassin du fleuve Sénégal à partir des données de dix stations de référence. Le choix des stations obéit à des critères de qualité des données (lacunes peu nombreuses et de proximité avec le bassin versant. Dans un premier temps, des tests statistiques d'homogénéité ont été appliqués aux séries de pluies annuelles de l'origine des stations à 2005. Les séries analysées présentent toutes des ruptures. Sur les dix stations étudiées, huit présentent une rupture comprise entre 1960 et 1970 et les déficits ultérieurs varient entre 12 et 24 %. À l'échelle mensuelle, après reconstitution des données manquantes, il apparaît que les précipitations ont diminué significativement pour presque tous les mois entre les deux périodes. À l'échelle journalière, l'analyse des fractions pluviométriques journalières met en évidence une tendance à la diminution du cumul annuel moyen des pluies supérieures à 40 mm (qui sont considérées comme les grosses pluies à partir des années de rupture. Nous avons ensuite caractérisé la variabilité spatiale des précipitations annuelles moyennes sur 30 et 10 ans, puis les écarts par rapport à la décennie de référence 1961-1970. Il apparaît ainsi que le sud du bassin présente les excédents les plus forts durant les périodes excédentaires, mais aussi les déficits les plus élevés en périodes déficitaires.Runoff and consequently water resources constitute the response of watersheds to pluviometric impulses

    The propagation of an alkaline wave through a clay rock has been investigated- The wave is generated by a cementitious matrix through the Callovo-Oxfordian argillite of the Meuse Haute-Marne Laboratory (-480 m depth). The argillite itself is composed of quartz, micas, calcite and an interstratified l/S. In order to characterise the interactions between the alkaline fluid and the argillaceous medium, dynamic column experiments have been carried out. The originality of the investigation methodology consists in exploiting the data generated from the breakthrough curves as well as from the characterisation of the solids extracted from the columns. Two types of processes having totally different reaction times have hence been thoroughly studied: - Fast surface adsorption and condensation reactions: On the one hand cation adsorption reactions by site ionisation have been characterised. They are responsible of the buffering effect of the clays. On the other hand an original reaction of calcium compound condensation in the interlayer space of the swelling clays has been revealed. These processes have been modelled and their simulations with the IMPACT calculation code showed that the models elaborated were very satisfying. - Strongly kinetically limited dissolution/precipitation reactions: The main primary phases dissolved are quartz and interstratified l/S. The precipitation of secondary phases are mainly C(A)SH and zeolites. After the injection of an alkaline fluid for 6 months at 60 deg C, the argillite is strongly amorphized but only 20 to 30% of the quartz and the interstratified I/S are dissolved. Therefore, dissolution kinetics of the primary phases and the solubility products of the main secondary phases have been determined. (author)

    Due to the prevailing positivistic view on science, qualitative research has only a modest place within the social sciences. There is, however, a growing awareness that a purely quantitative approach is not always satisfactory. This is for instance the case in the field of research into the quality

    This article examines constructivism, a paradigm in qualitative research that has been propagated by Egon Guba, Yvonna Lincoln, and Norman Denzin. A distinction is made between whether the basic presuppositions of constructivism are credible compared to those of a competing paradigm and whether constructivism's beliefs are internally consistent.…

    2009-12-01

    Within the context of selection of a site for a future deep storage for high- and intermediate-level activity and long life wastes, this report comments the various results of geological investigations and characterizations performed on this site during the past years. It notices that the most recent results (2007 and 2008) do not put previous conclusions (2005) into question. It recalls the required geological characteristics for such a storage site and compares them with the site characteristics. The IRSN agrees with the technical criteria adopted by the ANDRA for the choice of a zone of interest for a deepened investigation, and more particularly for this particular zone located on the territory of both French departments of Meuse and Haute-Marne

  17. Modelling of permafrost freezing and melting and the impact of a climatic cycle on groundwater flow at the Meuse/Haute-Marne site

    2011-01-01

    A fully coupled three-dimensional groundwater flow and heat transport (convection-conduction) model has been developed, including permafrost. The model covers the entire Paris basin and is focused on the Meuse/Haute-Marne Sector area and the Bure investigation site. The model was calibrated on the basis of the present hydro-thermal situation. The studied time period corresponds to what is considered a typical climatic cycle of length 130,000 year. A build-up of a superficial glacial ice mass is not included in the model; it is assumed that accumulated snow will melt during the summer months. The temperature boundary condition on top of the model is specified as a time-varying surface temperature. The temperatures are derived from an estimate of the future climatic evolution. It is the changes with time of the prescribed temperatures along the topography that drives all changes in groundwater flow, temperature and permafrost inside the model. The simulations are transient, but the initial condition of the base case represents a steady state situation. The simulated time period, for reaching a steady state situation of groundwater flows and temperatures in the deep and highly permeable layers of the Dogger (in the Sector area) is considerable (in the range of 50,000. years), depending on perturbation studied (e.g. a change in surface temperature of 5 deg.) and convergence criteria. The simulated depth of the permafrost varies in space and time during the studied glacial periods. Within the area studied (the Sector area), the simulated permafrost reaches a maximum depth of approx. 110 m. This is a median depth taking into account the spatial distribution of the permafrost. The lowest simulated temperature in the lower parts of the Callovo-Oxfordian clay stone, in the immediate vicinity of the Bure investigation site (in the Sector area), is approx. 14.5 deg. C, which is approx. 7.5 deg. C lower than the initial temperature (22 deg. C). A full reversion back to the

    Void fraction measurements were made in two phase flow boiling systems at high pressures in a uniformly heated, rectangular channel with a high aspect ratio. The local void fraction values were calculated from measurements of the absorption of a thin collimated X-ray beam (2 mm x 0.05 mm). The mean void fraction in a horizontal section results from integration of the local values across the section. At a fixed measuring station the quality and- void fraction were varied by changing the heat flux, flow rate and pressure systematically. Two channels were used differing in length and thickness (150.8 cm x 5.3 cm x 0.2 cm and the significant features of this study are: -1) The void fraction measurements are among the first obtained at such high pressure (80 to 140 kg/cm{sup 2}); -2) In the experimental region under consideration the measurements are systematic and numerous enough to allow accurate interpolations: mass velocity from 50 to 220 g/cm{sup 2}.s, heat flux from 40 to 170 W/cm{sup 2} and calculated steam quality from -0.2 to 0.2; -3) Many tests were performed under local boiling conditions with the mean temperature of the fluid below the saturation temperature; and -4) These results were compared to the predictions of certain models presented in the literature and simple empirical formulae were developed to fit the experimental results.

    In this work a study is made more particularly of two points: the production of high purity water and the estimation of this purity by means of conductivity measurements. As far as water purification is concerned it is observed that the de-ionisation produced by ion exchange resins in mixed beds leads to a water having a lower conductivity than that obtained by distillation. This low conductivity however, measured at the column exit before the water comes into contact with air is not stable. In fact the carbon dioxide in the water gives rise to an equilibrium with production of the ions HCO{sub 3}{sup -}, CO{sub 3}{sup --}. These ions are retained during the passage of the water through the resins. They reappear again at the column exit as a result of the displacement of the hydration equilibrium of CO{sub 2}; because of this the conductivity of the water increases with time. The water obtained by successive distillations does not behave in the same way because no carbon dioxide is present. Distillation is however a costly purification process on an industrial scale, especially if large quantities of water have to be treated. The measurement of these low conductivities is very delicate. The method employed makes use of a direct current and gives reproducible results if care is taken to exclude interfering electric fields by screening the apparatus. (author) [French] Au cours de ce travail nous etudions plus particulierement deux points: l'obtention d'eau de haute purete et l'estimation de cette purete grace a la mesure de sa conductivite. En ce qui concerne la purification de l'eau nous constatons que la deionisation effectuee par les resines echangeuses d'ions en lits melanges conduit a l'obtention d'une eau de conductivite plus faible que celle recueillie par distillations. Mais cette faible conductivite, mesuree a l'abri de l'air immediatement a la sortie de la colonne, n'est pas stable. En effet, dans l'eau, le gaz carbonique donne lieu a l'etablissement d

    Columnar defects can be introduced in high T_c superconductors by irradiation with high energy heavy ions. The concentration of these artificial pinning centers with a well characterized morphology is easily controlled. The pinning efficiency of these defects has been often demonstrated, mainly from magnetization measurements. In the present work, measurements of the electrical resistance along the c axis, R_c(T), in the presence of columnar defects are presented. They show the ability of these defects to prevent the thermal fluctuations effects. The measurements have been performed on the same crystal before and after the heavy ion irradiation. L'irradiation aux ions lourds de haute énergie permet d'introduire des défauts colonnaires amorphes dans les supraconducteurs à haute T_c. Ces centres de pinning artificiel, de morphologie connue, sont introduits en concentration facile à maîtriser. L'efficacité de ces défauts a été très souvent démontrée à partir de mesures d'aimantation. L'étude présentée ici : mesure de la résistance selon l'axe c, R_c(T), en présence de défauts colonnaires parallèles à l'axe c, montre que ces défauts sont capables de s'opposer efficacement à l'effet des fluctuations thermiques. Les mesures ont été faites sur le même monocristal avant et après l'irradiation.

  2. Characterisation of the hydraulic properties within the EDZ around drifts at level -490 m of the Meuse/Haute-Marne URL: A methodology for consistent interpretation of hydraulic tests

    Science.gov (United States)

    Baechler, S.; Lavanchy, J. M.; Armand, G.; Cruchaudet, M.

    In order to investigate potential changes of the hydraulic properties of the EDZ over time in the Meuse/Haute-Marne underground research laboratory (URL), several hydraulic tests campaigns have been carried out between 2005 and 2008 in dedicated boreholes. After several test series, inconsistencies were noticed in the results, indicating, in particular cases, erratic, inexplicable property changes over time and spatial contrasts. It was therefore difficult to determine reliably potential trends of the EDZ hydraulic properties. It appeared necessary to re-evaluate both the interpretation concepts and assumptions applied to the numerical analyses of test data on the EDZ, trying to better constrain the flow model and the parameter variables. In order to improve the understanding of the geometrical, geomechanical and hydraulic properties of the EDZ, independent information from other investigation methods has been used to critically revise the conceptual model and formation parameters. In particular, results from a diffusion experiment and ultrasonic measurements allowed constraining the extent of the mechanical damaged zone around the borehole (BDZ). Storativity parameters were fitted due to their expected variability. Indeed, high storativity values can be presumed under the unsaturated conditions of the EDZ. The results of the reanalyses, performed with the numerical borehole simulator MULTISIM, demonstrated the good quality and consistency of the revised conceptual model with constrained BDZ and variable storativity. Overall the new simulation results obtained from selected test series are now very consistent. The revised conceptual model demonstrated its capacity to better represent the evolution and extension of the EDZ around a drift in Meuse/Haute-Marne URL. Further consistency checks are proposed to confirm the new model assumptions and the estimates of the single phase flow model in the EDZ.

    A research project in nursing or nursing education is probably only complete once the findings have been published. This paper offers a format for writing a qualitative research report for publication. It suggests, at least, the following sections: introduction, aims of the study, review of the literature, sample, data collection methods, data analysis methods, findings, discussion, conclusion, abstract. Each of these sections is addressed along with many written-out examples. In some sections, alternative approaches are suggested. The aim of the paper is to help the neophyte researcher to structure his or her report and for the experienced researcher to reflect on his or her current practice. References to other source material on qualitative research are given.

That’s why it is imperative, in Brazil, the development of strategies and method to aid the decision making during the design process, focused on high quality environmental. This paper presents a decision support tool based on the principles of sustainable construction developed by the Project, Architecture and Sustainability Research Group (GPAS of Federal University of Rio de Janeiro – Brazil. The methodology has been developed for the selection of a preliminary design of a laboratory to be built at Rio Technology Park at the University campus. The support provided by GPAS occurred in three stages: the elaboration of the Reference Guide for the competitors, the development of a methodology to evaluate the proposed solutions (based on environmental performance criteria and the assistance of the members of jury in the trial phase. The theoretical framework was based upon the concepts of the bioclimatic architecture, the procedures specified by the certification HQE® (Haute Qualité Environnementale and the method suggested by the ADDENDA® architecture office.

    2017-07-01

    Full Text Available Rating systems for assessing the environmental impact of buildings are technical instruments that aim to evaluate the environmental impact of buildings and construction projects. In some cases, these rating systems can also cover urban-scale projects, community projects, and infrastructures. These schemes are designed to assist project management in making the projects more sustainable by providing frameworks with precise criteria for assessing the various aspects of a building’s environmental impact. Given the growing interest in sustainable development worldwide, many rating systems for assessing the environmental impact of buildings have been established in recent years, each one with its peculiarities and fields of applicability. The present work is motivated by an interest in emphasizing such differences to better understand these rating systems and extract the main implications to building design. It also attempts to summarize in a user-friendly form the vast and fragmented assortment of information that is available today. The analysis focuses on the six main rating systems: the Building Research Establishment Environmental Assessment Methodology (BREEAM, the Comprehensive Assessment System for Built Environment Efficiency (CASBEE, the Deutsche Gesellschaft für Nachhaltiges Bauen (DGNB, the Haute Qualité Environnementale (HQETM, the Leadership in Energy and Environmental Design (LEED, and the Sustainable Building Tool (SBTool.

    Qualitative secondary analysis (QSA) is the use of qualitative data that was collected by someone else or was collected to answer a different research question. Secondary analysis of qualitative data provides an opportunity to maximize data utility, particularly with difficult-to-reach patient populations. However, qualitative secondary analysis methods require careful consideration and explicit description to best understand, contextualize, and evaluate the research results. In this article, we describe methodologic considerations using a case exemplar to illustrate challenges specific to qualitative secondary analysis and strategies to overcome them.

    Document available in extended abstract form only. Understanding of the fate and of the impact of gas produced by corrosion of metals, microbial degradation and the radiolysis of water within a deep geological disposal repository for radioactive waste, is of major relevance in the performance assessment including the long-term evolution of the repository. To address these issues, the French national Agency for the management of radioactive waste (Andra) has directed a field scale experiment examining the mechanisms controlling gas entry and gas migration in the Callovo-Oxfordian (COX) clay, the proposed host rock of the French deep geological repository project. This experiment, called PGZ1, studies the migration of nitrogen in the COX based on gas injection tests performed in a borehole of the Meuse/Haute Marne URL. This experiment is currently being performed under the auspices of the Euratom 7. Framework FORGE project. In this poster, we provide an overview on the field data and a basic analysis of the data. The advanced interpretation of the data was based on numerical modeling of the two-phase flow with 3 different approaches and numerical codes. The experimental layout consists of three boreholes. Two parallel boreholes (PGZ1201 and PGZ1202) were drilled from the GED drift and are equipped with a triple interval system to monitor the pressure evolutions in 3 intervals, associated with the hydraulic and gas injection tests in the selected test interval (PGZ1201, middle interval). The third borehole (PGZ1031) was drilled from the GEX drift and is equipped with an extensometer probe, to monitor potential deformation associated with the resulting stress changes. An initial hydraulic test (HYDRO1) was performed in the test interval to estimate the hydraulic conductivity of the COX prior to gas testing. The hydraulic test consisted in a sequence of injections of synthetic formation water (pressure pulse followed by a constant pressure and a final shut-in phase

    Document available in extended abstract form only. Fluid pressure or hydraulic head measured in wells in geological formations can respond to Earth tidal forces and atmospheric pressure variations. At Andra Meuse/Haute-Marne underground research laboratory located in Bure (France), water level and fluid pressure are measured in several boreholes in the Callovo-Oxfordian clay formation (COX) and in overlying geological formations. One of these boreholes (EST207) is equipped with a multi-packer system monitoring 11 intervals, including 8 in the COX. The recorded fluid pressures in EST207 were analyzed to determine possible Earth tidal responses. In this borehole, the fluid pressure and atmospheric pressure variations data are recorded every fifteen minutes and 6.5 years of such data from 2004/06/02 to 2010/12/31 were analyzed. Various perturbed data, gaps, drift and abnormal data were corrected through a data preprocessing process. Data interpolation and filtering processes were performed to have data available every 15 minutes at 0, 15, 30 and 45 minutes on the hour. A spectral analysis (Fast Fourier Transform) of each pressure data series shows amplitude peaks at frequencies corresponding to various Earth tidal frequencies: diurnal and semi diurnal waves can be identified. Spectral analyses were also performed on the atmospheric pressure data. The solar semi diurnal wave (S2) was identified. The 'Earth Tides ETERNA package' was used to separate the waves according to the frequencies bands. The analyses performed using ETERNA are indicated as 'Earth Tidal Analyses' (ETAN). Tidal parameters are estimated from ETAN: amplitudes A and its standard deviation σ(A)[hPa], phase φ for the main waves in diurnal and semi diurnal frequencies bands before and after atmospheric pressure variations correction. The barometric efficiency (BE) and its standard deviation σ (BE) as regression coefficient is calculated. The atmospheric pressure data are also analyzed with ETERNA; the

On connait l'interet qu'il y a a garder dans un circuit de reacteur de l'eau de tres haute resistivite (plusieurs centaines a quelques millions {omega}.cm): abaissement de la corrosion, abaissement du taux de radiolyse, abaissement de la radioactivite des circuits et canalisations, les elements autres que les constituants de l'eau transportes par celle-ci devenant generalement radioactifs par leur passage au coeur du reacteur. Si la circulation d'eau se fait a des temperatures inferieures a 45 deg.

Par contre, pour des temperatures plus elevees surtout au-dessus de 100 deg. C, leur utilisation n'est pas possible, la degradation de ces hauts polymeres etant tres rapide. De meme, l'action des rayonnements, par exemple ceux des produits fixes par les echangeurs d'ions, detruit irremediablement les chaines organiques constituant le squelette de ces echangeurs.

    2007-01-01

    The gap between classical mechanics and quantum mechanics has an important interpretive implication: the Universe must have an irreducible fundamental level, which determines the properties of matter at higher levels of organization. We show that the main parameters of any fundamental model must be theory-independent. Moreover, such models must also contain discrete identical entities with constant properties. These conclusions appear to support the work of Kaniadakis on subquantum mechanics. A qualitative analysis is offered to suggest compatibility with relevant phenomena, as well as to propose new means for verification

    Qualitative research methodologies are being used more frequently in audiology as it allows for a better understanding of the perspectives of people with hearing impairment. This article describes why and how international interdisciplinary qualitative research can be conducted. This paper is based on a literature review and our recent experience with the conduction of an international interdisciplinary qualitative study in audiology. We describe some available qualitative methods for sampling, data collection, and analysis and we discuss the rationale for choosing particular methods. The focus is on four approaches which have all previously been applied to audiologic research: grounded theory, interpretative phenomenological analysis, conversational analysis, and qualitative content analysis. This article provides a review of methodological issues useful for those designing qualitative research projects in audiology or needing assistance in the interpretation of qualitative literature.

    The purpose of this article was to describe feminism and to propose the integration of a feminist method into qualitative nursing methodology in order to expand the body of nursing knowledge. The world view of feminism including philosophy, epistemology and methodology was outlined, and a feminist grounded theory and feminist ethnography were suggested as a way of strengthening nursing research methodology using literature review. Four different philosophical perspectives of feminism, that is, liberal feminism, radical feminism, Marxist feminism, and social feminism were described. Also epistemological perspectives including feminist empiricism, feminist standpoint, and postmodern feminism, were explained and were related to the methodology and methods of feminism. To enhance the strengths of nursing research within the feminist perspectives, feminist grounded theory and feminist ethnography were exemplified in the paradigm of qualitative nursing research. This paper suggested that incorporation of feminist approaches within nursing is a valuable attempt to expand the body of nursing knowledge and to enhance the quality of nursing care services by rectifying male-oriented knowledge and by empowering women in the care of other people as well as themselves.

    The production of high purity stable or radioactive isotopes ({>=} 99.99 per cent) using electromagnetic separation require for equipment having a high resolving power. Besides, and in order to collect rare or short half-life isotopes, the efficiency of the ion-source must be high ({eta} > 5 to 10 per cent). With this in view, the source built operates at high temperatures (2500-3000 C) and makes use of ionisation by electronic bombardment or of thermo-ionisation. A summary is given in the first part of this work on the essential characteristics of the isotope separator ion Sources; a diagram of the principle of the source built is then given together with its characteristics. In the second part are given the values of the resolving power and of the efficiency of the Grenoble isotope separator fitted with such a source. The resolving power measured at 10 per cent of the peak height is of the order of 200. At the first magnetic stage the efficiency is between 1 and 26 per cent for a range of elements evaporating between 200 and 3000 C. Thus equipped, the separator has for example given, at the first stage, 10 mg of {sup 180}Hf at (99.69 {+-} 0.1) per cent corresponding to an enrichment coefficient of 580; recently 2 mg of {sup 150}Nd at (99.996 {+-} 0.002) per cent corresponding to an enrichment coefficient of 4.2 x 10{sup 5} has been obtained at the second stage.

    This paper provides a primer for qualitative research in medical education. Our aim is to equip readers with a basic understanding of qualitative research and prepare them to judge the goodness of fit between qualitative research and their own research questions. We provide an overview of the reasons for choosing a qualitative research approach and potential benefits of using these methods for systematic investigation. We discuss developing qualitative research questions, grounding research in a philosophical framework, and applying rigorous methods of data collection, sampling, and analysis. We also address methods to establish the trustworthiness of a qualitative study and introduce the reader to ethical concerns that warrant special attention when planning qualitative research. We conclude with a worksheet that readers may use for designing a qualitative study. Medical educators ask many questions that carefully designed qualitative research would address effectively. Careful attention to the design of qualitative studies will help to ensure credible answers that will illuminate many of the issues, challenges, and quandaries that arise while doing the work of medical education.

    Cleland, Jennifer Anne

    2017-06-01

    Qualitative research is very important in educational research as it addresses the "how" and "why" research questions and enables deeper understanding of experiences, phenomena and context. Qualitative research allows you to ask questions that cannot be easily put into numbers to understand human experience. Getting at the everyday realities of some social phenomenon and studying important questions as they are really practiced helps extend knowledge and understanding. To do so, you need to understand the philosophical stance of qualitative research and work from this to develop the research question, study design, data collection methods and data analysis. In this article, I provide an overview of the assumptions underlying qualitative research and the role of the researcher in the qualitative process. I then go on to discuss the type of research objectives which are common in qualitative research, then introduce the main qualitative designs, data collection tools, and finally the basics of qualitative analysis. I introduce the criteria by which you can judge the quality of qualitative research. Many classic references are cited in this article, and I urge you to seek out some of these further reading to inform your qualitative research program.

    2016-07-01

    The purpose of this methodology paper is to describe an approach to qualitative design known as qualitative descriptive that is well suited to junior health sciences researchers because it can be used with a variety of theoretical approaches, sampling techniques, and data collection strategies. It is often difficult for junior qualitative researchers to pull together the tools and resources they need to embark on a high-quality qualitative research study and to manage the volumes of data they collect during qualitative studies. This paper seeks to pull together much needed resources and provide an overview of methods. A step-by-step guide to planning a qualitative descriptive study and analyzing the data is provided, utilizing exemplars from the authors' research. This paper presents steps to conducting a qualitative descriptive study under the following headings: describing the qualitative descriptive approach, designing a qualitative descriptive study, steps to data analysis, and ensuring rigor of findings. The qualitative descriptive approach results in a summary in everyday, factual language that facilitates understanding of a selected phenomenon across disciplines of health science researchers. © The Author(s) 2016.

    Document available in extended abstract form only. ANDRA is directly responsible for all scientific data acquired in real time and wire-line at the Meuse Haute- Marne underground research laboratory. To fulfil the needs for the acquisition, storage and display of realtime data, Andra decided to develop and install a system called SAGD (Systeme d'Acquisition et de Gestion des Donnees). With this view, a system was designed to: - Determine the acquisition tools and methods so that technical failures would not result in the loss of data or the acquisition of erroneous data, - Store (conservation) in the long-term all data in a single place in a single form, - Allow the diffusion and free access of data to the large community of ANDRA researchers, partners and service contractors in a single fluid way whatever the source of the data. - Help external communication through a user friendly and easy to understand presentation of the recorded data. S.A.G.D fulfils these objectives by: - Making available in real time, and through a single system, all experimental data under acquisition at the MHM Center and Mont Terri laboratory, - Displaying the recorded data on temporal windows and specific time step, - Allowing remote control of the experimentations, - Ensuring the traceability of all recorded information, - Ensuring data storage in a data base. S.A.G.D has been deployed in the first experimental drift at -445 m in November 2004. It was subsequently extended to the underground Mont Terri laboratory in Switzerland in 2005 and to the entire surface logging network of the Meuse / Haute-Marne Center in 2008. The SAGD computer network is an autonomous network consisting of optical fiber links which transmits experimentation data to the servers and computers in the control room, whether they originate from the bottom of a borehole or surface level. A high speed link between Mont Terri and Bure allows remote control of all the experimentations and the centralization of all

    The qualitative evaluation of system logic models is described as it pertains to assessing the reliability and safety characteristics of nuclear systems. Qualitative analysis of system logic models, i.e., models couched in an event (Boolean) algebra, is defined, and the advantages inherent in qualitative analysis are explained. Certain qualitative procedures that were developed as a part of fault-tree analysis are presented for illustration. Five fault-tree analysis computer-programs that contain a qualitative procedure for determining minimal cut sets are surveyed. For each program the minimal cut-set algorithm and limitations on its use are described. The recently developed common-cause analysis for studying the effect of common-causes of failure on system behavior is explained. This qualitative procedure does not require altering the fault tree, but does use minimal cut sets from the fault tree as part of its input. The method is applied using two different computer programs. 25 refs

    Qualitative translational research refers to the "bench-to-bedside" enterprise of harnessing knowledge from the basic sciences to produce new treatment options or nursing interventions for patients. Three evidence-based translational problems related to qualitative translational research discussed this year address the interfaces among the nursing paradigm, the basic sciences, and clinical nursing work. This article illustrates the definition of translational science and translational blocks of evidence-based practice; discusses the qualitative research perspective in evidence synthesis, evidence translation and evidence utilization; and discusses the research questions that must be answered to solve the problems of the three translational gaps from the qualitative research perspective. Qualitative inquiry has an essential role to play in efforts to improve current healthcare-provider nursing interventions, experiences, and contexts. Thus, it is vital to introduce qualitative perspectives into evidence-based practice from the knowledge discovery through to the knowledge implementation process.

    2016-03-01

    Patients with fibromyalgia report periods of symptom exacerbation, colloquially referred to as "flares" and despite clinical observation of flares, no research has purposefully evaluated the presence and characteristics of flares in fibromyalgia. The purpose of this qualitative study was to describe fibromyalgia flares in a sample of patients with fibromyalgia. Using seven open-ended questions, patients were asked to describe how they perceived fibromyalgia flares and triggers and alleviating factors associated with flares. Patients were also asked to describe how a flare differs from their typical fibromyalgia symptoms and how they cope with fibromyalgia flares. Content analysis was used to analyze the text. A total of 44 participants completed the survey. Responses to the seven open-ended questions revealed three main content areas: causes of flares, flare symptoms, and dealing with a flare. Participants identified stress, overdoing it, poor sleep, and weather changes as primary causes of flares. Symptoms characteristic of flares included flu-like body aches/exhaustion, pain, fatigue, and variety of other symptoms. Participants reported using medical treatments, rest, activity and stress avoidance, and waiting it out to cope with flares. Our results demonstrate that periods of symptom exacerbation (i.e., flares) are commonly experienced by patients with fibromyalgia and symptoms of flares can be differentiated from every day or typical symptoms of fibromyalgia. Our study is the first of its kind to qualitatively explore characteristics, causes, and management strategies of fibromyalgia flares. Future studies are needed to quantitatively characterize fibromyalgia flares and evaluate mechanisms of flares. © 2015 American Academy of Pain Medicine. All rights reserved.

    We describe a simple step-by-step guide to qualitative interpretation of galaxy spectra. Rather than an alternative to existing automated tools, it is put forward as an instrument for quick-look analysis and for gaining physical insight when interpreting the outputs provided by automated tools. Though the recipe is for general application, it was developed for understanding the nature of the Automatic Spectroscopic K-means-based (ASK) template spectra. They resulted from the classification of all the galaxy spectra in the Sloan Digital Sky Survey data release 7, thus being a comprehensive representation of the galaxy spectra in the local universe. Using the recipe, we give a description of the properties of the gas and the stars that characterize the ASK classes, from those corresponding to passively evolving galaxies, to H II galaxies undergoing a galaxy-wide starburst. The qualitative analysis is found to be in excellent agreement with quantitative analyses of the same spectra. We compare the mean ages of the stellar populations with those inferred using the code STARLIGHT. We also examine the estimated gas-phase metallicity with the metallicities obtained using electron-temperature-based methods. A number of byproducts follow from the analysis. There is a tight correlation between the age of the stellar population and the metallicity of the gas, which is stronger than the correlations between galaxy mass and stellar age, and galaxy mass and gas metallicity. The galaxy spectra are known to follow a one-dimensional sequence, and we identify the luminosity-weighted mean stellar age as the affine parameter that describes the sequence. All ASK classes happen to have a significant fraction of old stars, although spectrum-wise they are outshined by the youngest populations. Old stars are metal-rich or metal-poor depending on whether they reside in passive galaxies or in star-forming galaxies.

    Qualitative studies are gaining their credibility after a period of being misinterpreted as "not being quantitative." Qualitative method is a broad umbrella term for research methodologies that describe and explain individuals' experiences, behaviors, interactions, and social contexts. In-depth interview, focus groups, and participant observation are among the qualitative methods of inquiry commonly used in psychiatry. Researchers measure the frequency of occurring events using quantitative methods; however, qualitative methods provide a broader understanding and a more thorough reasoning behind the event. Hence, it is considered to be of special importance in psychiatry. Besides hypothesis generation in earlier phases of the research, qualitative methods can be employed in questionnaire design, diagnostic criteria establishment, feasibility studies, as well as studies of attitude and beliefs. Animal models are another area that qualitative methods can be employed, especially when naturalistic observation of animal behavior is important. However, since qualitative results can be researcher's own view, they need to be statistically confirmed, quantitative methods. The tendency to combine both qualitative and quantitative methods as complementary methods has emerged over recent years. By applying both methods of research, scientists can take advantage of interpretative characteristics of qualitative methods as well as experimental dimensions of quantitative methods.

    Qualitative methodology is extensively used in a wide range of scientific areas, such as Sociology and Psychology, and it is been used to study individual and household decision making processes. However, in the Transportation Planning and Engineering domain it is still infrequent to find in the travel behavior literature studies using qualitative techniques to explore activity-travel decisions. The aim of this paper is first, to provide an overview of the types of qualitative techniques available and to explore how to correctly implement them. Secondly, to highlight the special characteristics of qualitative methods that make them appropriate to study activity-travel decision processes. Far from been an unempirical or intuitive methodology, using qualitative methods properly implies a strong foundation on theoretical frameworks, a careful design of data collection and a deep data analysis. For such a purpose, a review of the scarce activity-travel behavior literature using qualitative methods, or a combination of qualitative and quantitative approaches, is presented. The use of qualitative techniques can play a role of being a supplementary way of obtaining information related to activity-travel decisions which otherwise it would be extremely difficult to find. This work ends with some conclusions about how qualitative research could help in making progress on activity-travel behavior studies. (Author)

    The theory of chaos offers useful tools for systems analysis. However, models of complex systems are based on a network of inconsistent, space and uncertain knowledge items. Traditional quantitative methods of chaos analysis are therefore not applicable. The paper by the same authors [Vicha T, Dohnal M. Qualitative identification of chaotic systems behaviours. Chaos, Solitons and Fractals, in press, [Log. No. 601019] ] presents qualitative interpretation of some chaos concepts. There are only three qualitative values positive/increasing, negative/decreasing and zero/constant. It means that any set of qualitative multidimensional descriptions of unsteady state behaviours is discrete and finite. A finite upper limit exists for the total number of qualitatively distinguishable scenarios. A set of 21 published chaotic models is solved qualitatively and 21 sets of all existing qualitative scenarios are presented. The intersection of all 21 scenario sets is empty. There is no such a behaviour which is common for all 21 models. The set of 21 qualitative models (e.g. Lorenz, Roessler) can be used to compare chaotic behaviours of an unknown qualitative model with them to evaluate if its chaotic behaviours is close to e.g. Lorenz chaotic model and how much

    Sample sizes must be ascertained in qualitative studies like in quantitative studies but not by the same means. The prevailing concept for sample size in qualitative studies is “saturation.” Saturation is closely tied to a specific methodology, and the term is inconsistently applied. We propose...... the concept “information power” to guide adequate sample size for qualitative studies. Information power indicates that the more information the sample holds, relevant for the actual study, the lower amount of participants is needed. We suggest that the size of a sample with sufficient information power...... and during data collection of a qualitative study is discussed....

    Qualitative research is an umbrella term for an array of attitudes and strategies for conducting inquiries that are aimed at discerning how human beings understand, experience, and interpret the social world. It is employed in many different academic disciplines most particularly in the social sciences and humanities, however recently more and more qualitative research is being conducted under the medical sciences including dentistry and orthodontics. This is due to its nature of in-depth investigation, which can provide answers to questions that cannot be satisfactorily answered using quantitative methods alone. The aims of this article are to discuss the characteristics of qualitative research, to review the orthodontic English literature, and to highlight the advantages of qualitative research in orthodontics. The literature review yielded several important conclusions regarding qualitative research in orthodontics: 1. most of the qualitative research done in orthodontics chose to use semi structured in-depth interviews for data collection; 2. qualitative research highlights aspects that are very important, and sometimes crucial to everyday practice and long term treatment; 3. there is a lack of qualitative studies in the field of orthodontics. Taking into account the nature of the orthodontic treatment, which is a prolonged one, demanding of a good orthodontist-patient rapport, and a wide perspective on behalf of the clinician, filling the gap in the discipline through conducting more qualitative studies aimed at understanding the point of view of the patient, as well as that of the clinician, may be beneficial for the improvement of the treatment.

    Full Text Available La diagraphie acoustique est classiquement utilisée pour fournir la lenteur des formations. Les enregistrements en champ total obtenus dans des puits fortement déviés ou horizontaux peuvent être traités pour fournir des sections de microsismique de puits qui ont une investigation latérale d'une dizaine de mètres par rapport au drain. Cet article présente les résultats d'expérimentations réalisées dans une carrière calcaire située en Bourgogne (France. Un puits fortement dévié (10 degrés a été foré dans l'unité géologique oolithe blanche qui a une épaisseur de 80 m environ. Des diagraphies acoustiques et de la sismique haute résolution ont été enregistrées dans le puits dévié. En diagraphie acoustique, deux jeux de données ont été enregistrés : une section à déport constant et un point de tir commun à très grand nombre de traces et à distance entre traces centimétrique. Le traitement des données met en évidence des réflexions internes a l'oolithe blanche situées à quelques mètres par rapport au drain. La diagraphie acoustique ne permet pas d'éclairer le toit et le mur de l'unité oolithe blanche. Cet objectif est partiellement atteint par une sismique très haute résolution de puits. Ce type de sismique travaille dans une bande de fréquences intermédiaire entre la sismique de puits classique et la diagraphie acoustique. Elle nécessite le développement d'outils particuliers, notamment au niveau des sources de puits. Une collection point de tir commun de données de sismique très haute résolution obtenues avec une source prototype de type impulsionnel montre des réflexions correspondant à des réflecteurs situés à plusieurs dizaines de mètres (~40 m par rapport au drain. Les résultats des expérimentations montrent le potentiel de la diagraphie acoustique et de la sismique haute résolution de puits à décrire une unité réservoir à différentes échelles.

    Full Text Available Les roches basaltiques de l’Atlas de Béni-Mellal (Haut-Atlas Central, Maroc, mises en place, dans les différents bassins synclinaux de la région, se manifestent en deux horizons volcaniques B1 et B2. Les deux événements éruptifs sont d’âge Jurassique moyen pour les coulées de l’horizon B1 et d’âge Crétacé inférieur pour celles de l’horizon B2. Les roches sont caractérisées par un faciès des basaltes à olivines. La composition de leurs clinopyroxènes est marquée par deux tendances : augite au niveau des basaltes à olivine du B1 et diopside au niveau de ceux du B2. La composition géochimique sur roche totale dévoile le caractère transitionnel de ces roches. La relative dissimilitude géochimique signalée au niveau des basaltes des deux horizons peut être expliquée par un début du changement de la nature du magmatisme de la région en relation avec l’évolution géodynamique du domaine atlasique.

    Ce travail se situe dans le cadre de l'expérience ATLAS auprès du Grand Collisionneur Hadronique (LHC) qui sera construit au CERN. Il consiste en l'étude de la réponse en courant de détecteurs au silicium de grande surface, irradiés par des neutrons ou des protons de façon à reproduire l'environnement de hautes radiations auquel le détecteur ATLAS devra faire face. A l'aide d'une modélisation du transport des charges produites par le passage de particules alpha ou bêta dans un détecteur au silicium et d'un ensemble de données expérimentales, il est possible d'obtenir certaines caractéristiques électriques importantes des détecteurs. Ces caractéristiques sont: la concentration effective de dopants (ce qui détermine la tension de désertion d'un semi-conducteur), le piégeage des porteurs de charge (donnant l'efficacité de la collection des charges), et les mobilités des électrons et des trous (influençant le temps nécessaire à la collection des charges).

    L'expérience LHCb, menée dans le cadre du CERN, dispose d'un réseau standard pour acquérir les données produites par les collisions du LHC. Les différents serveurs qui font partie de ce réseau, supportent de nombreux services. En l'état, une panne physique peut rendre un service complètement indisponible, et peut-être interrompre l'acquisition de données. C'est pour cela qu'il faut que le système d'acquisition de données et le système de commande soient les plus fiables possibles. Pour résoudre ce problème, il existe une solution: la haute disponibilité, basée sur une redondance de matériel et la mise en place de cluster. Cette solution peut être amélioré par l'utilisation conjointe de mécanismes de virtualisations. Ma tâche a été d'étudier et de comparer différents types d'outil de virtualisation et de les implémenter sur un cluster.

    2011-01-01

    Background Qualitative research appears to be gaining acceptability in medical journals. Yet, little is actually known about the proportion of qualitative research and factors affecting its publication. This study describes the proportion of qualitative research over a 10 year period and correlates associated with its publication. Design A quantitative longitudinal examination of the proportion of original qualitative research in 67 journals of general medicine during a 10 year period (1998–2007). The proportion of qualitative research was determined by dividing original qualitative studies published (numerator) by all original research articles published (denominator). We used a generalized estimating equations approach to assess the longitudinal association between the proportion of qualitative studies and independent variables (i.e. journals' country of publication and impact factor; editorial/methodological papers discussing qualitative research; and specific journal guidelines pertaining to qualitative research). Findings A 2.9% absolute increase and 3.4-fold relative increase in qualitative research publications occurred over a 10 year period (1.2% in 1998 vs. 4.1% in 2007). The proportion of original qualitative research was independently and significantly associated with the publication of editorial/methodological papers in the journal (b = 3.688, P = 0.012); and with qualitative research specifically mentioned in guidelines for authors (b = 6.847, Pqualitative research was associated only with journals published in the UK in comparison to other countries, yet with borderline statistical significance (b = 1.776, P = 0.075). The journals' impact factor was not associated with the publication of qualitative research. Conclusions Despite an increase in the proportion of qualitative research in medical journals over a 10 year period, the proportion remains low.

    2007-01-01

    The frequency of qualitative studies in the Emergency Medicine Journal, while still low, has increased over the last few years. All take a generic approach and rarely conform to established qualitative approaches such as phenomenology, ethnography and grounded theory. This generic approach is no doubt selected for pragmatic reasons but can be weakened by a lack of rigor and understanding of qualitative research. This paper explores qualitative approaches and then focuses on “best practice” fo...

    To compare the contribution of "trial-sibling" and "unrelated" qualitative studies in complex intervention reviews. Researchers are using qualitative "trial-sibling" studies undertaken alongside trials to provide explanations to understand complex interventions. In the absence of qualitative "trial-sibling" studies, it is not known if qualitative studies "unrelated" to trials are helpful. Trials, "trial-sibling," and "unrelated" qualitative studies looking at three health system interventions were identified. We looked for similarities and differences between the two types of qualitative studies, such as participants, intervention delivery, context, study quality and reporting, and contribution to understanding trial results. Reporting was generally poor in both qualitative study types. We detected no substantial differences in participant characteristics. Interventions in qualitative "trial-sibling" studies were delivered using standardized protocols, whereas interventions in "unrelated" qualitative studies were delivered in routine care. Qualitative "trial-sibling" studies alone provided insufficient data to develop meaningful transferrable explanations beyond the trial context, and their limited focus on immediate implementation did not address all phenomena of interest. Together, "trial-sibling" and "unrelated" qualitative studies provided larger, richer data sets across contexts to better understand the phenomena of interest. Findings support inclusion of "trial-sibling" and "unrelated" qualitative studies to explore complexity in complex intervention reviews. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available In this contribution I begin by reviewing past views on the future of qualitative social research. In different ways, all of these views give the same account of a problematic present state which must be overcome by following their own particular "mandatory directives" for future developments. I then discuss four structural mechanisms from which current problems in the transmission of qualitative and interpretative designs or approaches originate. Recently, supporters of "post-qualitative research" have addressed such problems by arguing for a form of strong theorism in qualitative social research. However, this type of response can lead back to an outdated dominance of theory over research and empirical substance. In conclusion, some alternative options for navigating qualitative and interpretative research through post-positivist waters are discussed. URN: http://nbn-resolving.de/urn:nbn:de:0114-fqs1401165

    Qualitative inquiry requires that collected data is organised in a meaningful way, and this is referred to as data analysis. Through analytic processes, researchers turn what can be voluminous data into understandable and insightful analysis. This paper sets out the different approaches that qualitative researchers can use to make sense of their data including thematic analysis, narrative analysis, discourse analysis and semiotic analysis and discusses the ways that qualitative researchers can analyse their data. I first discuss salient issues in performing qualitative data analysis, and then proceed to provide some suggestions on different methods of data analysis in qualitative research. Finally, I provide some discussion on the use of computer-assisted data analysis.

    To conceptualise and discuss dissemination bias in qualitative research. It is likely that the mechanisms leading to dissemination bias in quantitative research, including time lag, language, gray literature, and truncation bias also contribute to dissemination bias in qualitative research. These conceptual considerations have informed the development of a research agenda. Further exploration of dissemination bias in qualitative research is needed, including the extent of non-dissemination and related dissemination bias, and how to assess dissemination bias within qualitative evidence syntheses. We also need to consider the mechanisms through which dissemination bias in qualitative research could occur to explore approaches for reducing it. Copyright © 2017 Elsevier Inc.

Evaluating the international impact of qualitative research and qualitative computing requires a consideration of the vast amount of qualitative research over the last decades, as well as thoughtfulness about the uneven and unequal way in which qualitative research and qualitative computing are present in different fields of study and geographical regions. To understand the international impact of qualitative computing requires evaluation of the digital divide and the huge differences between center and peripheries. The international impact of qualitative research, and, in particular qualitative computing, is the question at the heart of this array of selected papers from the "Qualitative Computing: Diverse Worlds and Research Practices Conference." In this article, we introduce the reader to the goals, motivation, and atmosphere at the conference, taking place in Istanbul, Turkey, in 2011. The dialogue generated there is still in the air, and this introduction is a call to spread that voice. URN: http://nbn-resolving.de/urn:nbn:de:0114-fqs1202285

    The vast majority of radiography research is subject to critique and evaluation from peers in order to justify the method and the outcome of the study. Within the quantitative domain, which the majority of medical imaging publications tend to fall into, there are prescribed methods for establishing scientific rigour and quality in order to critique a study. However, researchers within the qualitative paradigm, which is a developing area of radiography research, are often unclear about the most appropriate methods to measure the rigour (standards and quality) of a research study. This article considers the issues related to rigour, reliability and validity within qualitative research. The concepts of reliability and validity are briefly discussed within traditional positivism and then the attempts to use these terms as a measure of quality within qualitative research are explored. Alternative methods for research rigour in interpretive research (meanings and emotions) are suggested in order to compliment the existing radiography framework that exists for qualitative studies. The authors propose the use of an established model that is adapted to reflect the iterative process of qualitative research. Although a mechanistic approach to establishing rigour is rejected by many qualitative researchers, it is argued that a guide for novice researchers within a developing research base such as radiography is appropriate in order to establish the credibility and trustworthiness of a qualitative study.

  10. Qualitative identification of chaotic systems behaviours

    There are only three qualitative values positive, negative and zero. This means that there is a maximal number of qualitatively distinguishable scenarios, prescribed by the number of variables and the highest qualitative derivative taken into consideration. There are several chaos related tasks, which can be solved with great difficulties on the numerical level if multidimensional problems are studied. One of them is the identification of all qualitatively different behaviours. To make sure that all distinctive qualitative scenarios are identified a qualitative interpretation of a classical quantitative phase portrait is used. The highest derivatives are usually the second derivatives as it is not possible to safely identify higher derivatives if tasks related to ecology or economics are studied. Two classical models are discussed - Damped oscillation (non chaotic) and Lorenz model (chaotic). There are 191 scenarios of the Lorenz model if only the second derivatives are considered. If the third derivatives are taken into consideration then the number of scenarios is 2619. Complete qualitative results are given in details

    The objectives of this project were: (1) to investigate the implications of qualitative modeling techniques for problems arising in the monitoring, diagnosis, and design of Space Station subsystems and procedures; (2) to identify the issues involved in using qualitative models to enhance and automate engineering functions. These issues include representing operational criteria, fault models, alternate ontologies, and modeling continuous signals at a functional level of description; and (3) to develop a prototype collection of qualitative models for fluid and thermal systems commonly found in Space Station subsystems. Potential applications of qualitative modeling to space-systems engineering, including the notion of intelligent computer-aided engineering are summarized. Emphasis is given to determining which systems of the proposed Space Station provide the most leverage for study, given the current state of the art. Progress on using qualitative models, including development of the molecular collection ontology for reasoning about fluids, the interaction of qualitative and quantitative knowledge in analyzing thermodynamic cycles, and an experiment on building a natural language interface to qualitative reasoning is reported. Finally, some recommendations are made for future research.

    2012-03-01

    Data analysis is a complex and contested part of the qualitative research process, which has received limited theoretical attention. Researchers are often in need of useful instructions or guidelines on how to analyze the mass of qualitative data, but face the lack of clear guidance for using particular analytic methods. The aim of this paper is to propose and discuss the Qualitative Analysis Guide of Leuven (QUAGOL), a guide that was developed in order to be able to truly capture the rich insights of qualitative interview data. The article describes six major problems researchers are often struggling with during the process of qualitative data analysis. Consequently, the QUAGOL is proposed as a guide to facilitate the process of analysis. Challenges emerged and lessons learned from own extensive experiences with qualitative data analysis within the Grounded Theory Approach, as well as from those of other researchers (as described in the literature), were discussed and recommendations were presented. Strengths and pitfalls of the proposed method were discussed in detail. The Qualitative Analysis Guide of Leuven (QUAGOL) offers a comprehensive method to guide the process of qualitative data analysis. The process consists of two parts, each consisting of five stages. The method is systematic but not rigid. It is characterized by iterative processes of digging deeper, constantly moving between the various stages of the process. As such, it aims to stimulate the researcher's intuition and creativity as optimal as possible. The QUAGOL guide is a theory and practice-based guide that supports and facilitates the process of analysis of qualitative interview data. Although the method can facilitate the process of analysis, it cannot guarantee automatic quality. The skills of the researcher and the quality of the research team remain the most crucial components of a successful process of analysis. Additionally, the importance of constantly moving between the various stages

    After the TMI nuclear power plant accident, the two topics of plant safety and operational efficiency became more important areas of artificial intelligence, which have difference characteristics. Qualitative deep model is the recently prospective technology of AI, that can overcome several handicaps of the existing expert systems such as lack of common sense reasoning. The application of AI to the large and complex system like nuclear power plants is typically and effectively done through a module-based hierarchical system. As each module has to be built with suitable AI system. Through the experiences of hierarchical system construction, we aimed to develop basic AI application schemes for the power plant safety and operational efficiency as well as basic technologies for autonomous power plants. The goal of the research is to develop qualitative reasoning technologies for nuclear power plants. For this purpose, the development of qualitative modeling technologies and qualitative behaviour prediction technologies of the power plant are accomplished. In addition, the feasibility of application of typical qualitative reasoning technologies to power plants is studied . The goal of the application is to develop intelligent control technologies of power plants, support technologies. For these purposes, we analyzed the operation of power plants according to its operation purpose: power generation operation, shut-down and start-up operation. As a result, qualitative model of basic components were sketched, including pipes, valves, pumps and heat exchangers. Finally, plant behaviour prediction technologies through qualitative plant heat transfer model and design support technologies through 2nd-order differential equation were developed. For the construction of AI system of power plants, we have studied on the mixed module based hierarchical software. As a testbed, we have considered the spent fuel system and the feedwater system. We also studied the integration

    Triangulation refers to the use of multiple methods or data sources in qualitative research to develop a comprehensive understanding of phenomena (Patton, 1999). Triangulation also has been viewed as a qualitative research strategy to test validity through the convergence of information from different sources. Denzin (1978) and Patton (1999) identified four types of triangulation: (a) method triangulation, (b) investigator triangulation, (c) theory triangulation, and (d) data source triangulation. The current article will present the four types of triangulation followed by a discussion of the use of focus groups (FGs) and in-depth individual (IDI) interviews as an example of data source triangulation in qualitative inquiry.

  20. Study of superconductors with high critical temperature by using the vibrating blade technique: anelastic properties, vortices dynamics; Etude des supraconducteurs a haute temperature critique par la technique de la lame vibrante: - proprietes anelastiques, - dynamique des vortex

    1991-10-04

    This research thesis reports the application of the vibrating blade technique to the study of high critical temperature superconductors, first for the anelastic properties, and then for vortices dynamics. As far as the study of anelastic properties is concerned, the author reports the measurement of dissipation and of Young modulus, between 4 K and 300 K and at about 1 khz, in YbaCuO ceramics with various oxygen content. A detailed study of the tetragonal phase reveals the existence of a single relaxation process, the magnitude of which depends on the compound oxygen content and on its thermal treatment. In the second part, the author reports the measurement, under magnetic field and within a temperature range lower than the superconducting critical temperature, of a YbaCuO crystal with two different oxygen concentrations. At low temperature, the author studies the contribution of vortices trapped in an irreversible state. At high temperature, this contribution disappears and thus defines an irreversibility line beyond which vortices are in a reversible regime. This line is studied for different magnetic field orientations with respect to CuO planes. It is interpreted in terms of de-trapping thermally activated by vortices [French] La technique de la lame vibrante a ete appliquee a l'etude des supraconducteurs a haute temperature critique, pour leurs proprietes anelastiques d'abord, pour la dynamique des vortex ensuite.

    This special issue is devoted to the proceedings of the workshops Peyresq Physics 11 and Peyresq Physics 12 on 'Micro and Macro Structure of Spacetime', which were held on the 17 23 June 2006 and 16 22 June 2007, respectively, in Peyresq, Alpes de Haute Provence, France, and organized by E Gunzig, B-L Hu and one of us (EV). These workshops are part of a series of annual meetings which bring together around 20 physicists active in different areas of theoretical physics. Uncovering the microscopic structures of spacetime is the goal of quantum gravity and string theory. It is often considered as the 'holy grail' of theoretical physics because it is believed that all fundamental forces are unified at that level of description. Macroscopic spacetime refers to astrophysical and cosmological structures and processes in the observable physical world, from black holes to the cosmos, from the second law to the arrow of time. The challenge theoretical physicists now face is to infer the micro structure of spacetime from the observed macro phenomena, and to deduce the multifarious manifestations of our world from any such candidate theory. To do so demands a careful re-examination of the foundational issues of quantum physics and general relativity (such as intrinsic and quantum gravity decoherence), the origin and nature of symmetries in spacetime (such as Lorentz symmetry) and the conditions where they may be violated, as well as their intersections (such as the physics of the early universe and the end states of black hole evolution). One asks how and why these two pillars of modern physics appear to be so incongruous with each other. Is it because their basic tenets and assumptions are at odds to each other? For these quests one needs to draw upon concepts and techniques from close disciplines such as those found in topology and geometry, or other subdisciplines of physics such as particle physics, strings and loops, statistical mechanics and mesoscopic phenomena, atomic

Un mode de recouvrement adapté des rubans d'acier confère au composite une bonne étanchéité et des caractéristiques mécaniques élevées.

  4. Experimental study and modeling of the propagation of an alkaline concentration wave coming from a cement matrix an passing through the argilite of the Meuse / Haute-Marne laboratory

    Roussel, Th.

    2001-12-01

    The propagation of an alkaline wave through a clay rock has been investigated- The wave is generated by a cementitious matrix through the Callovo-Oxfordian argillite of the Meuse Haute-Marne Laboratory (-480 m depth). The argillite itself is composed of quartz, micas, calcite and an interstratified l/S. In order to characterise the interactions between the alkaline fluid and the argillaceous medium, dynamic column experiments have been carried out. The originality of the investigation methodology consists in exploiting the data generated from the breakthrough curves as well as from the characterisation of the solids extracted from the columns. Two types of processes having totally different reaction times have hence been thoroughly studied: - Fast surface adsorption and condensation reactions: On the one hand cation adsorption reactions by site ionisation have been characterised. They are responsible of the buffering effect of the clays. On the other hand an original reaction of calcium compound condensation in the interlayer space of the swelling clays has been revealed. These processes have been modelled and their simulations with the IMPACT calculation code showed that the models elaborated were very satisfying. - Strongly kinetically limited dissolution/precipitation reactions: The main primary phases dissolved are quartz and interstratified l/S. The precipitation of secondary phases are mainly C(A)SH and zeolites. After the injection of an alkaline fluid for 6 months at 60 deg C, the argillite is strongly amorphized but only 20 to 30% of the quartz and the interstratified I/S are dissolved. Therefore, dissolution kinetics of the primary phases and the solubility products of the main secondary phases have been determined. (author)

    Full Text Available Résumé Vers la fin du 18e siècle, les Noirs marrons Aluku, descendants d’esclaves rebelles fuyant les plantations hollandaises et les Amérindiens Wayana, arrivant du Brésil, où ils fuyaient les chasseurs d’esclaves, se sont rencontrés sur le haut Maroni, en Guyane française. Ce partage d’un même lieu de vie a été l’occasion d’échanger un grand nombre de techniques, notamment en ce qui concerne l’agriculture itinérante sur brûlis, et les plantes cultivées. Toutefois notre étude montre que le culte des ancêtres chez les Noirs marrons a modifié leur cycle cultural (via la culture du riz, influençant ainsi leur gestion de l’environnement. De même la nature et la diversité des plantes cultivées diffèrent sensiblement en fonction des usages traditionnels et habitudes culinaires des deux sociétés. Les Aluku ont sélectionné de nombreuses espèces et variétés de plantes qui leur sont propres et sont liées à leurs racines africaines. Les Amérindiens cultivent des plantes spécifiques utiles au chamanisme (tabac et à leur artisanat traditionnel. De plus, leur perception de la nature implique des pratiques cultuelles différentes notamment avant le défrichage. Cette étude illustre l’influence de la diversité culturelle sur la gestion de l’agrobiodiversité et, de manière plus générale, sur l’adaptation de l’homme à son environnement.

  11. Perils and potentials in qualitative psychology.

    Brinkmann, Svend

    2015-06-01

    Famously, Ebbinghaus declared that psychology has a long past, but only a short history. Psychology, as something implicit to human conduct, is as old as the human race, but the science, as an explicit investigative reflection upon that conduct, is a recent invention. Within the short history of psychology, we find an even shorter history of qualitative psychology specifically. Although most founding fathers (Freud, Piaget, Bartlett etc.) worked as "qualitative psychologists", they found no need to thematize their methods of inquiry in this manner. Since around 1980, however, a field has established itself that can be called qualitative psychology. In this paper, I discuss how this field can move sensibly into the future, and I highlight two perils and two potentials. The perils stem from neo-positivism and a threatening "McDonaldization" of qualitative research, while the potentials are related to proliferation of new forms of inquiry and a transcending of disciplinary boundaries.

    Famously, Ebbinghaus declared that psychology has a long past, but only a short history. Psychology, as something implicit to human conduct, is as old as the human race, but the science, as an explicit investigative reflection upon that conduct, is a recent invention. Within the short history...... of psychology, we find an even shorter history of qualitative psychology specifically. Although most founding fathers (Freud, Piaget, Bartlett etc.) worked as “qualitative psychologists”, they found no need to thematize their methods of inquiry in this manner. Since around 1980, however, a field has established...... itself that can be called qualitative psychology. In this paper, I discuss how this field can move sensibly into the future, and I highlight two perils and two potentials. The perils stem from neo-positivism and a threatening “McDonaldization” of qualitative research, while the potentials are related...

    Full Text Available This paper discusses the development of a 14-inch ID high-pressure hybrid riser (10 000 psi for surface BOP drilling in ultra-deep water (10 000 ft. The high-pressure hybrid riser system is obtained by adapting and combining two existing technologies, previously developed by the IFP for other applications: – the Clip connector, a double breech-block type connector to provide a quick and safe connection for riser joints; – hybrid pipe technology, a steel pipe hoop-wound with tapes of carbon fibers impregnated with polyamide thermoplastic resin. IFP has developed a new 14-inch ID HP Clip connector for the hybrid riser application. The connector is capable of withstanding a 2.8 million pound tension and a 10 000 psi operating pressure. In addition, a 16-inch nominal OD hybrid riser pipe has been designed to replace the steel riser pipe with a thinnerwalled hoop-wound steel pipe. The significant weight savings that can be achieved with the hybrid riser pipe make it possible to design an effective riser architecture to withstand the high pressure and deep water requirements. Pursuant to design studies, a 14-inch ID prototype assembly consisting of two hybrid riser pipe sections with a high-pressure Clip connector was manufactured. A test program, including burst and collapse tests as well as cyclic fatigue testing, was formulated and carried out to qualify the performance of the Clip connector and hybrid riser pipe system. Completion of hybrid pipe additional fatigue testing and realization of a scale-one field testing of the hybrid riser are considered as the next steps of the project. To date, the main test results (burst, collapse, fatigue resistance confirm that the Clip connector and the hybrid pipe technologies are well suited for ultra-deep sea drilling with a surface BOP. However, the fatigue resistance of hybrid riser pipes still needs to be better characterized. Cet article présente le développement d’un riser hybride 14”ID haute

    Background Qualitative research is undertaken with randomized controlled trials of health interventions. Our aim was to explore the perceptions of researchers with experience of this endeavour to understand the added value of qualitative research to the trial in practice. Methods A telephone semi-structured interview study with 18 researchers with experience of undertaking the trial and/or the qualitative research. Results Interviewees described the added value of qualitative research for the trial, explaining how it solved problems at the pretrial stage, explained findings, and helped to increase the utility of the evidence generated by the trial. From the interviews, we identified three models of relationship of the qualitative research to the trial. In ‘the peripheral’ model, the trial was an opportunity to undertake qualitative research, with no intention that it would add value to the trial. In ‘the add-on’ model, the qualitative researcher understood the potential value of the qualitative research but it was viewed as a separate and complementary endeavour by the trial lead investigator and wider team. Interviewees described how this could limit the value of the qualitative research to the trial. Finally ‘the integral’ model played out in two ways. In ‘integral-in-theory’ studies, the lead investigator viewed the qualitative research as essential to the trial. However, in practice the qualitative research was under-resourced relative to the trial, potentially limiting its ability to add value to the trial. In ‘integral-in-practice’ studies, interviewees described how the qualitative research was planned from the beginning of the study, senior qualitative expertise was on the team from beginning to end, and staff and time were dedicated to the qualitative research. In these studies interviewees described the qualitative research adding value to the trial although this value was not necessarily visible beyond the original research team due

    2012-03-01

    This article contributes to the debate about the use of reliability assessments in qualitative research in general, and health promotion research in particular. In this article, I examine the use of reliability assessments in qualitative health promotion research in response to health promotion researchers' commonly held misconception that reliability assessments improve the rigor of qualitative research. All qualitative articles published in the journal Health Promotion International from 2003 to 2009 employing reliability assessments were examined. In total, 31.3% (20/64) articles employed some form of reliability assessment. The use of reliability assessments increased over the study period, ranging from qualitative articles decreased. The articles were then classified into four types of reliability assessments, including the verification of thematic codes, the use of inter-rater reliability statistics, congruence in team coding and congruence in coding across sites. The merits of each type were discussed, with the subsequent discussion focusing on the deductive nature of reliable thematic coding, the limited depth of immediately verifiable data and the usefulness of such studies to health promotion and the advancement of the qualitative paradigm.

    Due to its technical and economical advantages, concrete is nowadays the most used building material in civil engineering. Even if its use is known since nearly two centuries, its behavior has not been yet completely explained due to the complexity of its porous microstructure. This fact is quite evident under particular conditions such as, by instance, during an elevation of temperature. This condition can mainly occur in two cases: due to a casualty (e.g. a fire) or in normal use conditions (e.g. storage of nuclear rejects). This work aims at contributing to the study of the phenomena that can be observed in concrete exposed to high temperatures and, in particular, focuses on the study of the evolution of intrinsic permeability. The characterisation of permeability (which is hardly measurable in hot conditions) is necessary for describing and modelling transport phenomena which occur in porous media. An experimental study has been made in collaboration with the CEA. A real-scale hollow cylinder has been instrumented with gauges for studying the evolution of temperature and gas pressure fields inside concrete. Later, the cylinder has been then numerically modelled by means of a thermo-hydro-chemical (THC) and a thermo-hydro-chemo-mechanical (THCM) model. The THC model, implemented by means of the finite volume method, has allowed a first, qualitative study of the behaviour of concrete submitted to high temperature. This model, which, for sake of simplicity, has neglected all mechanical effects, has allowed the description of the main phenomena occurring inside concrete: mass transport, phase changes, microstructure evolution. Later, the modelling has been completed by means of the THCM model using the Hitecosp code, implemented by means of the finite element method at the university of Padua. This code allows a very complete description of the phenomena occurring inside concrete and takes into consideration the mechanical behavior of concrete by means of an

    The propagation of an alkaline wave through a clay rock has been investigated- The wave is generated by a cementitious matrix through the Callovo-Oxfordian argillite of the Meuse Haute-Marne Laboratory (-480 m depth). The argillite itself is composed of quartz, micas, calcite and an interstratified l/S. In order to characterise the interactions between the alkaline fluid and the argillaceous medium, dynamic column experiments have been carried out. The originality of the investigation methodology consists in exploiting the data generated from the breakthrough curves as well as from the characterisation of the solids extracted from the columns. Two types of processes having totally different reaction times have hence been thoroughly studied: - Fast surface adsorption and condensation reactions: On the one hand cation adsorption reactions by site ionisation have been characterised. They are responsible of the buffering effect of the clays. On the other hand an original reaction of calcium compound condensation in the interlayer space of the swelling clays has been revealed. These processes have been modelled and their simulations with the IMPACT calculation code showed that the models elaborated were very satisfying. - Strongly kinetically limited dissolution/precipitation reactions: The main primary phases dissolved are quartz and interstratified l/S. The precipitation of secondary phases are mainly C(A)SH and zeolites. After the injection of an alkaline fluid for 6 months at 60 deg C, the argillite is strongly amorphized but only 20 to 30% of the quartz and the interstratified I/S are dissolved. Therefore, dissolution kinetics of the primary phases and the solubility products of the main secondary phases have been determined. (author)

  13. Qualitative Methods in Mental Health Services Research

    Palinkas, Lawrence A.

    2014-01-01

    Qualitative and mixed methods play a prominent role in mental health services research. However, the standards for their use are not always evident, especially for those not trained in such methods. This paper reviews the rationale and common approaches to using qualitative and mixed methods in mental health services and implementation research based on a review of the papers included in this special series along with representative examples from the literature. Qualitative methods are used to provide a “thick description” or depth of understanding to complement breadth of understanding afforded by quantitative methods, elicit the perspective of those being studied, explore issues that have not been well studied, develop conceptual theories or test hypotheses, or evaluate the process of a phenomenon or intervention. Qualitative methods adhere to many of the same principles of scientific rigor as quantitative methods, but often differ with respect to study design, data collection and data analysis strategies. For instance, participants for qualitative studies are usually sampled purposefully rather than at random and the design usually reflects an iterative process alternating between data collection and analysis. The most common techniques for data collection are individual semi-structured interviews, focus groups, document reviews, and participant observation. Strategies for analysis are usually inductive, based on principles of grounded theory or phenomenology. Qualitative methods are also used in combination with quantitative methods in mixed method designs for convergence, complementarity, expansion, development, and sampling. Rigorously applied qualitative methods offer great potential in contributing to the scientific foundation of mental health services research. PMID:25350675

    Full Text Available Social media technologies have attracted substantial attention among many types of users including researchers who have published studies for several years. This article presents an overview of trends in qualitative and mixed methods social media research literature published from 2007 through 2013. A collection of 229 qualitative studies were identified through a systematic literature review process. A subset of 55 of these articles report studies involving a combination of qualitative and quantitative methods. Articles were reviewed, analyzed, and coded through a qualitative content analysis approach. Overall trends are presented with respect to the entire collection of articles followed by an analysis of mixed methods research approaches identified in the subset of 55 studies. The most commonly used research approaches involved collecting data from people through interview, focus group, and survey methodologies. Content analysis was the second most commonly used approach whereby researchers use Facebook posts, Tweets (Twitter posts, YouTube videos, or other social media content as a data source. Many of the studies involving combinations of quantitative and qualitative data followed a design resembling Creswell and Plano Clark’s basic mixed methods typology (e.g., convergent parallel, explanatory sequential, and exploratory sequential.

    2017-03-01

    Health care research requires different methodological approaches such as qualitative and quantitative analyzes to understand the phenomena under study. Qualitative research is usually the least considered. Central elements of the qualitative method are that the object of study is constituted by perceptions, emotions and beliefs, non-random sampling by purpose, circular process of knowledge construction, and methodological rigor throughout the research process, from quality design to the consistency of results. The objective of this work is to contribute to the methodological knowledge about qualitative research in health services, based on the implementation of the study, “The transition process from pediatric to adult services: perspectives from adolescents with chronic diseases, caregivers and health professionals”. The information gathered through the qualitative methodology facilitated the understanding of critical points, barriers and facilitators of the transition process of adolescents with chronic diseases, considering the perspective of users and the health team. This study allowed the design of a transition services model from pediatric to adult health services based on the needs of adolescents with chronic diseases, their caregivers and the health team.

    The third and final discussion paper of the German Network of Health Services Research's (DNVF) "Qualitative Methods Working Group" demonstrates methods for the evaluation and quality of qualitative research in health services research. In this paper we discuss approaches described in evaluating qualitative studies, including: an orientation to the general principles of empirical research, an approach-specific course of action, as well as procedures based on the research-process and criteria-oriented approaches. Divided into general and specific aspects to be considered in a qualitative study quality evaluation, the central focus of the discussion paper undertakes an extensive examination of the process and criteria-oriented approaches. The general aspects include the participation of relevant groups in the research process as well as ethical aspects of the research and data protection issues. The more specific aspects in evaluating the quality of qualitative research include considerations about the research interest, research questions, and the selection of data collection methods and types of analyses. The formulated questions are intended to guide reviewers and researchers to evaluate and to develop qualitative research projects appropriately. The intention of this discussion paper is to ensure a transparent research culture, and to reflect on and discuss the methodological and research approach of qualitative studies in health services research. With this paper we aim to initiate a discussion on high quality evaluation of qualitative health services research. © Georg Thieme Verlag KG Stuttgart · New York.

    The amount of inspection effort for verification of declared nuclear material needs to be optimized in the situation where qualitative and quantitative measures are applied. Game theory was referred to investigate the relation of detection probability and deterrence of diversion. Payoffs used in the theory were quantified for cases of conventional safeguards and integrated safeguards by using AHP, Analytical Hierarchy Process. Then, it became possible to estimate detection probability under integrated safeguards which had equivalent deterrence capability for detection probability under conventional safeguards. In addition the distribution of inspection effort for qualitative and quantitative measures was estimated. Although the AHP has some ambiguities in quantifying qualitative factors, its application to optimization in safeguards is useful to reconsider the detection probabilities under integrated safeguards.

    Full Text Available In this paper one aspect of the transition that must be made by experienced clinicians who become involved in conducting qualitative health research is examined, specifically, the differences between clinical and research interviewing. A clinician who is skillful and comfortable carrying out a clinical interview may not initially apprehend the important differences between these categories and contexts of interviewing. This situation can lead to difficulties and diminished quality of data collection because the purpose, techniques and orientation of a qualitative research interview are distinct from those of the clinical interview. Appreciation of these differences between interview contexts and genres, and strategies for addressing challenges associated with these differences, can help clinician researchers to become successful qualitative interviewers.

    Full Text Available The purpose of this paper is to describe the most relevant features of qualitative research in order to show how, from the Epistemology of the Known Subject perspective I propose, it is necessary to review first the ontological and then the epistemological grounds of this type of inquiry. I begin by following the path that leads from the Epistemology of the Knowing Subject to the Epistemology of the Known Subject, proposed as a new and non exclusive way of knowing.

    Abstract Background: The increase in medical ethical regulations and bureaucracy handled by institutional review boards and healthcare institutions puts the researchers using qualitative methods in a challenging position. Method: Based on three different cases from three different research studies...... research ethical guidelines related to informed consent and doing no harm. Third, the article argues for the importance of having research ethical guidelines and review boards to question and discuss the possible ethical dilemmas that occur in qualitative research. Discussion and conclusion: Research...... ethics must be understood in qualitative research as relational, situational, and emerging. That is, that focus on ethical issues and dilemmas has to be paid attention on the spot and not only at the desktop....

    2014-03-01

    There is little information in the literature describing how students learn qualitative research. This article describes an approach to learning that is based on the pedagogical approach of Dinkins' Socratic-Hermeneutic Shared Inquiry. This approach integrates shared dialog as an essential aspect of learning. The qualitative pedagogy described in this article focused on three questions: What is knowing in qualitative research? How do we come to know qualitative research? What can we do with qualitative research? Students learned the basics of qualitative research within a context that fostered interpretive inquiry. In this way, the course framework mirrored the combination of interviewing, storytelling, and journeying toward understanding that constitute qualitative research. © 2013.

  11. Concurrent analysis: towards generalisable qualitative research.

    Science.gov (United States)

    Snowden, Austyn; Martin, Colin R

    2011-10-01

    This study develops an original method of qualitative analysis coherent with its interpretivist principles. The objective is to increase the likelihood of achieving generalisability and so improve the chance of the findings being translated into practice. Good qualitative research depends on coherent analysis of different types of data. The limitations of existing methodologies are first discussed to justify the need for a novel approach. To illustrate this approach, primary evidence is presented using the new methodology. The primary evidence consists of a constructivist grounded theory of how mental health nurses with prescribing authority integrate prescribing into practice. This theory is built concurrently from interviews, reflective accounts and case study data from the literature. Concurrent analysis. Ten research articles and 13 semi-structured interviews were sampled purposively and then theoretically and analysed concurrently using constructivist grounded theory. A theory of the process of becoming competent in mental health nurse prescribing was generated through this process. This theory was validated by 32 practising mental health nurse prescribers as an accurate representation of their experience. The methodology generated a coherent and generalisable theory. It is therefore claimed that concurrent analysis engenders consistent and iterative treatment of different sources of qualitative data in a manageable manner. This process supports facilitation of the highest standard of qualitative research. Concurrent analysis removes the artificial delineation of relevant literature from other forms of constructed data. This gives researchers clear direction to treat qualitative data consistently raising the chances of generalisability of the findings. Raising the generalisability of qualitative research will increase its chances of informing clinical practice. © 2010 Blackwell Publishing Ltd.

  12. Employing a Qualitative Description Approach in Health Care Research

    Bradshaw, Carmel; Atkinson, Sandra; Doody, Owen

    2017-01-01

    A qualitative description design is particularly relevant where information is required directly from those experiencing the phenomenon under investigation and where time and resources are limited. Nurses and midwives often have clinical questions suitable to a qualitative approach but little time to develop an exhaustive comprehension of qualitative methodological approaches. Qualitative description research is sometimes considered a less sophisticated approach for epistemological reasons. Another challenge when considering qualitative description design is differentiating qualitative description from other qualitative approaches. This article provides a systematic and robust journey through the philosophical, ontological, and epistemological perspectives, which evidences the purpose of qualitative description research. Methods and rigor issues underpinning qualitative description research are also appraised to provide the researcher with a systematic approach to conduct research utilizing this approach. The key attributes and value of qualitative description research in the health care professions will be highlighted with the aim of extending its usage. PMID:29204457

  16. From conditional oughts to qualitative decision theory

    Science.gov (United States)

    Pearl, Judea

    1994-01-01

    The primary theme of this investigation is a decision theoretic account of conditional ought statements (e.g., 'You ought to do A, if C') that rectifies glaring deficiencies in classical deontic logic. The resulting account forms a sound basis for qualitative decision theory, thus providing a framework for qualitative planning under uncertainty. In particular, we show that adding causal relationships (in the form of a single graph) as part of an epistemic state is sufficient to facilitate the analysis of action sequences, their consequences, their interaction with observations, their expected utilities, and the synthesis of plans and strategies under uncertainty.

    The results of experiments in the light water cooled D{sub 2}O reflected critical assembly ALIZE III have been compared to calculations. A diffusion model was used with 3 fast and epithermal groups and two overlapping thermal groups, which leads to good agreement of calculated and measured power maps, even in the case of strong variations of the neutron spectrum in the core. The difference of calculated and measured k{sub eff} was smaller than 0.5 per cent {delta}k/k. Calculations of void and structure material coefficients of the reactivity of 'black' rods in the reflector, of spectrum variations (Cd-ratio, Pu-U-ratio) and to the delayed photoneutron fraction in the D{sub 2}O reflector were made. Measurements of the influence of beam tubes on reactivity and flux distribution in the reflector were interpreted with regard to an optimum beam tube arrangement for the Franco- German High Flux Reactor. (author) [French] Les resultats des experiences faites dans la maquette critique ALIZE III, refrigeree a l'eau legere et reflechie par l'eau lourde, ont ete compares aux calculs. On a utilise un modele de la theorie de diffusion a trois groupes rapides et epithermiques et deux groupes thermiques qui se recouvrent. Ce modele a permis de calculer la distribution de puissance dans le coeur en bon accord avec les mesures, meme dans le cas d'une forte variation du spectre des neutrons dans le coeur. L'erreur entre k{sub eff} calcule et mesure etait inferieure a 0,5 pour cent {delta}k/k. Le coefficient de vide et des materiaux de structure, la reactivite des barres 'noires', les variations du spectre (rapport Cd, rapport Pu/U) et la fraction des photo-neutrons retardes sont egalement calcules. Les mesures de reactivite et de perturbation de flux dans le reflecteur, dues aux canaux, ont ete interpretees du point de vue d'un arrangement optimum des canaux pour le Reacteur a Haut Flux Franco-Allemand.

  5. Qualitative treatment of three-nucleon properties

    International Nuclear Information System (INIS)

    Efimov, V.

    1981-01-01

    An attempt is made at consistent qualitative treatment of the three-nucleon system. The approach used is based on the physical concept of effective three-nucleon long-range interaction resulting from the existence of the deuteron and the virtual singlet deuteron. Within the framework of the approach, a qualitative treatment of the triton properties, nucleon-deuteron scattering, and triton-disintegration reactions is carried out. The following topics are dealt with: the Phillips line, the triton D-wave admixture, the doublet effective range of the n-d scattering, the triton virtual state, the anomaly of the n-d elastic cross section near the three-body threshold, and the partial cross sections of the inelastic n-d scattering and of the triton photo- and electrodisintegration. The discussion of these topics includes the evaluation of three-nucleon parameters and the qualitative interpretation of experimental data and calculation results; some predictions are also made. The results of our analysis lead to the conclusion that the concept of effective three-nucleon long-range interaction can indeed serve as grounds for consistent qualitative treatment of the three-nucleon phenomena.

    1999-08-01

    Qualitative research is increasingly recognized and valued and its unique place in nursing research is highlighted by many. Despite this, some nurse researchers continue to raise epistemological issues about the problems of objectivity and the validity of qualitative research findings. This paper explores the issues relating to the representativeness or credibility of qualitative research findings. It therefore critiques the existing distinct philosophical and methodological positions concerning the trustworthiness of qualitative research findings, which are described as follows: quantitative studies should be judged using the same criteria and terminology as quantitative studies; it is impossible, in a meaningful way, for any criteria to be used to judge qualitative studies; qualitative studies should be judged using criteria that are developed for and fit the qualitative paradigm; and the credibility of qualitative research findings could be established by testing out the emerging theory by means of conducting a deductive quantitative study. The authors conclude by providing some guidelines for establishing the credibility of qualitative research findings.

    The purpose of this paper is to provide an account of how the validity issue related to qualitative research strategies within the IB field may be grasped from an at least partially subjectivist point of view. In section two, we will first assess via the aforementioned literature review the extent...... to which the validity issue has been treated in qualitative research contributions published in six leading English-language journals which publish IB research. Thereafter, in section three, we will discuss our findings and relate them to (a) various levels of a research project and (b) the existing...... literature on potential validity problems from a more subjectivist point of view. As a part of this step, we will demonstrate that the assumptions of objectivist and subjectivist ontologies and their corresponding epistemologies merit different canons for assessing research validity. In the subsequent...

    Advances in technology have provided new approaches for data collection methods and analysis for researchers. Data collection is no longer limited to paper-and-pencil format, and numerous methods are now available through Internet and electronic resources. With these techniques, researchers are not burdened with entering data manually and data analysis is facilitated by software programs. Quantitative research is supported by the use of computer software and provides ease in the management of large data sets and rapid analysis of numeric statistical methods. New technologies are emerging to support qualitative research with the availability of computer-assisted qualitative data analysis software (CAQDAS).CAQDAS will be presented with a discussion of advantages, limitations, controversial issues, and recommendations for this type of software use.

    1991-01-01

    Recent research on giant formation has focused on the need for qualitative explanations. The explanations have the following general, qualitative form: the polytrope n assumes a certain value, that makes (d ln r)/(d ln z) take on a very large value; large increases in r can then be explained in terms of small changes in the variable z. This form is applicable to all the explanations current in the literature: they all have (1) either implicitly or explicitly, both a hydrostatic component and a luminosity-opacity component, and (2) a reliance on singular solutions. Dimensional analysis reveals that power laws that assume the polytrope n to 5 are identical in both the hydrostatic and luminosity-based explanations. 12 refs

  1. [Qualitative research: which priority for scientific journals?].

    2016-04-01

    Quantitative and qualitative approaches in scientific research should not be looked at as separate or even opposed fields of thinking and action, but could rather offer complementary perspectives in order to build appropriate answers to increasingly complex research questions. An open letter recently published by the BMJ and signed by 76 senior academics from 11 countries invite the editors to reconsider their policy of rejecting qualitative research on the grounds of low priority and challenge the journal to develop a proactive, scholarly and pluralistic approach to research that aligns with its stated mission. The contents of the letter, the many voices raised by almost fifty rapid responses and the severe but not closed responses of the editors outline a stimulating debate and hopefully prelude some "change in emphasis", ensuring that all types of research relevant to the mission of the BMJ (as well as other core journals) are considered for publication and providing an evolving landmark for scientific and educational purposes.

Les évaluations faîtes à ce propos mettent le plus souvent l´accent sur les résultats que ces investissements ont et auront sur le processus de «réchauffement de l´économie fluminense». Néanmoins, certains observateurs se preocuppent des effets de ces investissements en termes de re-aménagement et développement du territoire. Quelques unes de ces préocupations sont liées à la basse capacité de réponse démontrée par le Pouvoir Public – en particulier les gouvernements locaux –confronté à un scénario conditionné par les décisions entrepreunariales formulées par un petit nombre de grandes corporations, comme c´est le cas autour du port d´Itaguai. Le présent article attire l´attention sur la nécessité d´agréger à ce débat la possibilité de création d´un espace institutionnel dédié à la formulation de politiques publiques négociées pour la gestion environnementale dans l´aire d´influence du port d´Itaguai, de manière à favoriser les dimensions sociales, environnementales et spatiales de ces dernières.Since approximately the year 2000 State of Rio de Janeiro is experiencing corporate investments which volume never had taken place before in its history. These investments are mainly associated to the oil & gas industry and to the steel industry, with an important participation of port and naval industry activities, as well as a dense pipeline network. The resulting facilities and their logistics drive the territorial dynamics of various regions within the state, especially of the coastal zone. The evaluations made on this respect focus more frequently the results that such investments are (or will be generating concerning the “recovery of the economy of the State of Rio de Janeiro”. However, the consequences of such agenda concerning issues such as territorial development have been pointed out as subjects deserving more

    Qualitative techniques are essential tools for identifying and assessing operational risk (OR). Their relevance in assessing OR can be understood due to the lack of a quantitative static model capable of capturing the dynamic operational risk profile which is shaped by managerial decisions. An operational risk profile obtained solely from historical loss data could further change due to corrective actions implemented by the bank after the occurrence of those events. This document introduces s...

  11. Hermeneutic Constructivism: An Ontology for Qualitative Research.

    Science.gov (United States)

    Peck, Blake; Mummery, Jane

    2018-02-01

    Qualitative research is entirely an operation with language, in language, and occasionally on language. This article suggests a tension between theoretical recognition of a multiplicity of human experience on one hand and a reliance upon practices of thematic representation that prioritize the common or the general over individualized experience. The fulcrum of this tension is the nature of language itself and its role in human experience and meaning-making. This article sets out the theoretical foundations of Hermeneutic Constructivism as one proposed approach to redress this problematic within many qualitative frameworks and open up an opportunity for a deeper and more nuanced understanding of human being. Within Hermeneutic Constructivism, a Fundamental Postulate and 11 elaborative corollaries detail a cogent relationship between language and the structures and processes of mental activity that support the human comportment toward understanding. The authors argue that this theoretical position is able to inform a model for qualitative research that makes possible an exploration of a person's experience at a deeper level of abstraction and that may provide an avenue for overcoming this identified tension.

    To explore some of the main methodological challenges faced by interviewers in Arab settings, particularly during interviews with psychiatric nurses. Interviews are a tool used commonly in qualitative research. However, the cultural norms and practices of interviewees must be considered to ensure that an appropriate interviewing style is used, a good interviewee-interviewer relationship formed and consent for participation obtained sensitively. A study to explore the nature of psychiatric nurses' practices that used unstructured interviews. This is a methodology paper that discusses a personal experience of addressing many challenges that are specific to qualitative interviewing in Arab settings, supported by literature on the topic. Suggestions for improving the interview process to make it more culturally sensitive are provided and recommendations for future research are made. Openness, flexibility and a reflexive approach by the researcher can help manage challenges in Arab settings. Researchers should allow themselves to understand the cultural elements of a population to adapt interviewing methods with the aim of generating high quality qualitative research.

  14. Qualitative biomechanical principles for application in coaching.

    2007-01-01

    Many aspects of human movements in sport can be readily understood by Newtonian rigid-body mechanics. Many of these laws and biomechanical principles, however, are counterintuitive to a lot of people. There are also several problems in the application of biomechanics to sports, so the application of biomechanics in the qualitative analysis of sport skills by many coaches has been limited. Biomechanics scholars have long been interested in developing principles that facilitate the qualitative application of biomechanics to improve movement performance and reduce the risk of injury. This paper summarizes the major North American efforts to establish a set of general biomechanical principles of movement, and illustrates how principles can be used to improve the application of biomechanics in the qualitative analysis of sport technique. A coach helping a player with a tennis serve is presented as an example. The standardization of terminology for biomechanical principles is proposed as an important first step in improving the application ofbiomechanics in sport. There is also a need for international cooperation and research on the effectiveness of applying biomechanical principles in the coaching of sport techniques.

  15. On Generalization in Qualitatively Oriented Research

    Directory of Open Access Journals (Sweden)

    Philipp Mayring

    2007-09-01

    Full Text Available In this article, I open a debate about the importance and possibilities of generalization in qualitative oriented research. Generalization traditionally is seen as a central aim of science, as a process of theory formulation for further applications. Others criticize the concept in general, either because of the insufficiency of inductive arguments (POPPER, 1959 or because of context specificity of all scientific findings (LINCOLN & GUBA, 1985. In this paper, I argue that generalization is necessary in qualitative research, but we have to differentiate different aims of generalization: laws, rules, context specific statements, similarities and differences, and procedures. There are different possibilities to arrive at a generalization: analysis of total population, falsification, random or stratified samples, argumentative generalization, theoretical sampling, variation, and triangulation. Depending on the type of research or research design some of those strategies of generalization can be important for qualitative oriented research. This is discussed especially in respect to single case analysis. URN: urn:nbn:de:0114-fqs0703262

    To provide examples of a qualitative multiple case study to illustrate the specific strategies that can be used to ensure the credibility, dependability, confirmability and transferability of a study. There is increasing recognition of the valuable contribution qualitative research can make to nursing knowledge. However, it is important that the research is conducted in a rigorous manner and that this is demonstrated in the final research report. A multiple case study that explored the role of the clinical skills laboratory in preparing students for the real world of practice. Multiple sources of evidence were collected: semi-structured interviews (n=58), non-participant observations at five sites and documentary sources. Strategies to ensure the rigour of this research were prolonged engagement and persistent observation, triangulation, peer debriefing, member checking, audit trail, reflexivity, and thick descriptions. Practical examples of how these strategies can be implemented are provided to guide researchers interested in conducting rigorous case study research. While the flexible nature of qualitative research should be embraced, strategies to ensure rigour must be in place.

  17. Review Essay: Does Qualitative Network Analysis Exist?

    Directory of Open Access Journals (Sweden)

    Rainer Diaz-Bone

    2007-01-01

    Full Text Available Social network analysis was formed and established in the 1970s as a way of analyzing systems of social relations. In this review the theoretical-methodological standpoint of social network analysis ("structural analysis" is introduced and the different forms of social network analysis are presented. Structural analysis argues that social actors and social relations are embedded in social networks, meaning that action and perception of actors as well as the performance of social relations are influenced by the network structure. Since the 1990s structural analysis has integrated concepts such as agency, discourse and symbolic orientation and in this way structural analysis has opened itself. Since then there has been increasing use of qualitative methods in network analysis. They are used to include the perspective of the analyzed actors, to explore networks, and to understand network dynamics. In the reviewed book, edited by Betina HOLLSTEIN and Florian STRAUS, the twenty predominantly empirically orientated contributions demonstrate the possibilities of combining quantitative and qualitative methods in network analyses in different research fields. In this review we examine how the contributions succeed in applying and developing the structural analysis perspective, and the self-positioning of "qualitative network analysis" is evaluated.

    Full Text Available The article considers the way that digital research technologies and online environments increasingly support new forms of qualitative research that have emerged as a result of new user groups taking up the practice of social research. New practitioners of qualitative research have entered the field from societies where qualitative research is a newly-established practice, and new cadres of "citizen researchers" have turned to qualitative methods for non-academic purposes. These groups challenge accepted understandings of qualitative methods. The article uses the example of qualitative software as a case study of how qualitative research is enabled by new digital tools that help new user groups extend the application of qualitative research methods.

    Hadi, Muhammad Abdul; José Closs, S

    2016-06-01

    The use of qualitative research methodology is well established for data generation within healthcare research generally and clinical pharmacy research specifically. In the past, qualitative research methodology has been criticized for lacking rigour, transparency, justification of data collection and analysis methods being used, and hence the integrity of findings. Demonstrating rigour in qualitative studies is essential so that the research findings have the "integrity" to make an impact on practice, policy or both. Unlike other healthcare disciplines, the issue of "quality" of qualitative research has not been discussed much in the clinical pharmacy discipline. The aim of this paper is to highlight the importance of rigour in qualitative research, present different philosophical standpoints on the issue of quality in qualitative research and to discuss briefly strategies to ensure rigour in qualitative research. Finally, a mini review of recent research is presented to illustrate the strategies reported by clinical pharmacy researchers to ensure rigour in their qualitative research studies.
