    Quebec is a net importer of oil and it is clear that the reduction of its dependence with regards to hydrocarbons must be a main preoccupation. Moreover, the energy consumption per habitant of Quebec is higher than that of the majority of the other developed countries. This analysis looks at the choice on offer to the society of the province of Quebec, in terms of energy resources and technologies of today and tomorrow, in a context of sustainable development. [French] Le Quebec est un importateur net de petrole et il est clair que la reduction de sa dependance a l'egard des hydrocarbures doit etre une preoccupation de premier plan. De plus, la consommation energetique par habitant du Quebec est plus elevee que celle de la majorite des autres pays developpes. La presente analyse adresse les choix qui s'offrent a la societe quebecoise, en matiere de ressources et de technologies de l'energie d'aujourd'hui et de demain, dans un contexte de developpement durable.

    By its omnipresence in society, the energy question is at the heart of sustainable development issues. The engineer, as a central actor of human society development, is therefore tightly linked to the energy issue and he must actively contribute to resolve it by integrating to his practices the principles of sustainable development and by applying the solutions that arises. Part of these elements include as the main ones, listening to the consideration of citizens, becoming aware of the environment importance and reducing costs at all levels. The engineer is a social actor that cannot be ignored in the resolution of these issues. [French] Par son omnipresence dans la societe, la question energetique est au coeur des enjeux du developpement durable. L'ingenieur, etant un acteur central du developpement des societes humaines, est donc inextricablement lie a la question energetique qu'il doit contribuer activement a resoudre en integrant a sa pratique les principes du developpement durable et en appliquant les solutions qui en decoulent. Parmi ces elements, l'ecoute des considerations citoyennes, la prise de conscience de l'importance de l'environnement et la reduction des couts a tous les niveaux sont des elements centraux. L'ingenieur est un acteur social incontournable pour la resolution de ces enjeux.

    Full Text Available Cette contribution souligne le fait que la plupart des innovations techniques ont bénéficié d’arrangements institutionnels adaptés qui ont favorisé l’adoption de pratiques techniques nouvelles. Elle met en exergue la nécessité de considérer conjointement les innovations techniques et institutionnelles pour aider à réaliser un gain de productivité qui permettrait de renforcer la place des pays cotonniers de l’Afrique de l’Ouest et du Centre dans le monde. Malgré leur intérêt, les nouvelles technologies ne constituent pas la réponse unique, comme ce serait le cas dans les pays économiquement développés, dans la conception de nouvelles techniques culturales pour ces pays africains. Ces techniques doivent d’abord être conformes aux contraintes des paysans, par exemple, en termes de limitation de main-d’œuvre ou de finance. Le comportement des petits paysans face à l’incertitude et la limitation de leurs moyens est brièvement étudié. Cette analyse permet de mettre en évidence les éléments de cahier des charges des nouvelles techniques destinées à soulager les contraintes des paysans. Des exemples de techniques possibles sont présentés. Des cas spécifiques d’interaction entre innovation technique et innovation institutionnelle sont examinés. La mise au point de techniques efficaces et adaptées exige un changement dans le financement et dans la réalisation de la recherche.

  5. Developpement de mesures non destructives, par ondes ultrasonores, d'epaisseurs de fronts de solidification dans les reacteurs metallurgiques

    Science.gov (United States)

    Floquet, Jimmy

    Dans les cuves d'electrolyse d'aluminium, le milieu de reaction tres corrosif attaque les parois de la cuve, ce qui diminue leur duree de vie et augmente les couts de production. Le talus, qui se forme sous l'effet des pertes de chaleur qui maintiennent un equilibre thermique dans la cuve, sert de protection naturelle a la cuve. Son epaisseur doit etre controlee pour maximiser cet effet. Advenant la resorption non voulue de ce talus, les degats generes peuvent s'evaluer a plusieurs centaines de milliers de dollars par cuve. Aussi, l'objectif est de developper une mesure ultrasonore de l'epaisseur du talus, car elle serait non intrusive et non destructive. La precision attendue est de l'ordre du centimetre pour des mesures d'epaisseurs comprenant 2 materiaux, allant de 5 a 20 cm. Cette precision est le facteur cle permettant aux industriels de controler l'epaisseur du talus de maniere efficace (maximiser la protection des parois tout en maximisant l'efficacite energetique du procede), par l'ajout d'un flux thermique. Cependant, l'efficacite d'une mesure ultrasonore dans cet environnement hostile reste a demontrer. Les travaux preliminaires ont permis de selectionner un transducteur ultrasonore a contact ayant la capacite a resister aux conditions de mesure (hautes temperatures, materiaux non caracterises...). Differentes mesures a froid (traite par analyse temps-frequence) ont permis d'evaluer la vitesse de propagation des ondes dans le materiau de la cuve en graphite et de la cryolite, demontrant la possibilite d'extraire l'information pertinente d'epaisseur du talus in fine. Fort de cette phase de caracterisation des materiaux sur la reponse acoustique des materiaux, les travaux a venir ont ete realises sur un modele reduit de la cuve. Le montage experimental, un four evoluant a 1050 °C, instrumente d'une multitude de capteurs thermique, permettra une comparaison de la mesure intrusive LVDT a celle du transducteur, dans des conditions proches de la mesure

Partant du constat que nous ne parlons pas forcément de la même chose quand nous parlons de communication il s’agit de présenter les concepts à partir d’un axe central: l’information n’est pas de la communication. Si la communication a un grand rôle dans l’évolution des organisations, elle ne peut pas tout. En rappelant les fondements de la communication nous montrons ce que peut être l’apport de la communication au développement des ressources humaines dans les organisations. La communication n’est pas un système unique, elle correspond bien à des besoins et à des règles. Elle ne peut s’appliquer d’une manière uniforme à tous les pays, toutes les organisations et toutes les personnes.

    Ce document contient les objectifs, le cheminement suivi et les résultats obtenus d'un projet visant à identifier le nombre d'onde sur différents types de plaques représentatives de ce qui est utilise en aéronautique. Dans une première partie, on y définit les enjeux du sujet, liés au domaine aéronautique et le contexte dans lequel ce projet se déroule. A la suite de quoi, est exposée la revue de l'état de l'art sur les méthodes existantes de mesure du nombre d'onde. Le projet en lui-même est ensuite défini avec un objectif principal fixé qui est de mesurer le nombre d'onde d'une plaque à partir de mesures vibratoires. Pour cela deux méthodes seront utilisées; la méthode de différence de phase permettant d'effectuer la mesure sur les plaques simples ou composites et la méthode du passage dans le domaine des nombres d'onde permettant cette même mesure sur des plaques plus complexes (plaque épaisse ou raidie par exemple). Pour chaque méthode, un cheminement équivalent est utilisé. Dans un premier temps, on développe et implémente la méthode choisie de manière basique, puis on réalise l'étude paramétrique permettant de connaitre les conditions optimales de fonctionnement des deux méthodes, enfin une validation expérimentale est réalisée. Dans ce document, les deux méthodes seront aussi comparées pour en déduire dans quelles conditions il faut utiliser l'une ou l'autre des méthodes. La méthode de la différence de phase donne de bons résultats dans le cas de plaques simples et composites si on est capable d'exciter suffisamment toutes la gamme de fréquence. La méthode du passage dans le domaine des nombres d'onde quant à elle est apte à mesurer le nombre d'onde sur tous types de plaques et dans toutes les directions si la zone de mesure est suffisamment grande.

    Full Text Available Cet article aborde la question du développement touristique dans les territoires insulaires, et propose un éclairage plus particulier sur la valorisation touristique des espaces naturels. Il présente, tout d’abord, les enjeux du développement durable du tourisme dans les territoires insulaires français. En fonction de la taille des îles, de leur accessibilité, de l’importance de leur fréquentation touristique on peut distinguer différents types d’îles.  Le défi pour chaque  île réside dans la mise en oeuvre d’un projet en étroite adéquation avec ses propres ressources et les spécificités de son territoire pour assurer un développement durable du tourisme. L’article illustre ensuite l’exemple de la valorisation touristique des espaces naturels, l’ambivalence du rapport entre le tourisme et ces espaces. Il s’attache à montrer en quoi le tourisme qui peut être parfois à l’origine de la  dégradation des espaces naturels peut être source de retombées positives pour l’environnement dès lors que les acteurs du territoire sont en situation de gérer leur développement.

    Full Text Available L’évaluation des politiques publiques prend une place institutionnelle de plus en plus importante. La commande de l’évaluation donne lieu à l’élaboration d’un cahier des charges, qui précise notamment les questions évaluatives stratégiques à traiter. Pour parvenir à une définition judicieuse de ces questions, la réalisation, en amont, d’une démarche interdisciplinaire comprenant une phase d’analyse de politique complétée d’une étude des modalités de mise en oeuvre s’avère nécessaire. A travers l’exemple de l’évaluation intermédiaire du Contrat Territorial d’Exploitation (CTE en Limousin, nous tentons de montrer en quoi le graphe d’objectifs peut constituer un outil adapté pour révéler la théorie d’action de la politique publique. La conception du cahier des charges contribue également à éclairer la décision publique en favorisant l’implication et la concertation des divers partenaires. Celle-ci est d’autant plus précieuse qu’il s’agit d’une politique de développement durable, visant, entre autres, à mieux gérer les biens publics environnementaux.An important step in a sustainable policy evaluation: the conception of terms of reference, The experience of the Land Management Contract mid-term review in Limousin.

    Que ce soit dans les domaines des procedes industriels ou de l'imagerie medicale, on a assiste ces deux dernieres decennies a un developpement croissant des techniques optiques de diagnostic. L'engouement pour ces methodes repose principalement sur le fait qu'elles sont totalement non invasives, qu'elle utilisent des sources de rayonnement non nocives pour l'homme et l'environnement et qu'elles sont relativement peu couteuses et faciles a mettre en oeuvre comparees aux autres techniques d'imagerie. Une de ces techniques est la Tomographie Optique Diffuse (TOD). Cette methode d'imagerie tridimensionnelle consiste a caracteriser les proprietes radiatives d'un Milieu Semi-Transparent (MST) a partir de mesures optiques dans le proche infrarouge obtenues a l'aide d'un ensemble de sources et detecteurs situes sur la frontiere du domaine sonde. Elle repose notamment sur un modele direct de propagation de la lumiere dans le MST, fournissant les predictions, et un algorithme de minimisation d'une fonction de cout integrant les predictions et les mesures, permettant la reconstruction des parametres d'interet. Dans ce travail, le modele direct est l'approximation diffuse de l'equation de transfert radiatif dans le regime frequentiel tandis que les parametres d'interet sont les distributions spatiales des coefficients d'absorption et de diffusion reduit. Cette these est consacree au developpement d'une methode inverse robuste pour la resolution du probleme de TOD dans le domaine frequentiel. Pour repondre a cet objectif, ce travail est structure en trois parties qui constituent les principaux axes de la these. Premierement, une comparaison des algorithmes de Gauss-Newton amorti et de Broyden- Fletcher-Goldfarb-Shanno (BFGS) est proposee dans le cas bidimensionnel. Deux methodes de regularisation sont combinees pour chacun des deux algorithmes, a savoir la reduction de la dimension de l'espace de controle basee sur le maillage et la regularisation par penalisation de Tikhonov

    During the European Council at Hampton Court (October 2005), the European Heads of State or Government expressed the desire to see Europe's energy policy revitalized, given the new and increasingly tough challenges facing Europe and the world today, in particular concerning energy security on the one hand, and the need to combat climate change on the other. These guidelines were confirmed and clarified by the European Council on 15 and 16 December 2005, which particularly 'stressed the importance of an integrated approach to climate change, energy and competitiveness objectives, and underlined the fact that strategies to invest in cleaner and more sustainable energy, both within the EU and more widely, can support a range of policy objectives, including energy security, competitiveness, employment, air quality and reduced greenhouse gas emissions'. To make a contribution to the debate around these strategic questions ongoing in many arenas, and pending the publication of new documents announced by the Commission and the Presidency of the Council concerning European energy policy, France wishes to make known its point of view and propose areas for action in order to promote solutions to encourage the creation of safer and more sustainable energy systems both within the EU and with our partners, which would be accessible to all. This involves: - guaranteeing that the energy we produce, import and consume for our economic and social development remains available and economically accessible to all, both today and in the future; - progressing towards sustainable use of energy in that it must take account of environmental impacts and the depletion of fossil resources; - developing employment by promoting energy efficiency, renewable energies and other low greenhouse gas emitting technologies. After a reminder of the context and stakes (part 1), suggestions are made with regard to policies (part 2) and means, concerning the various types of consumption on the energy demand side (part 3) and the energy supply side (part 4), which would enable the European Union and its member States to provide the best response to meeting the challenges we face. We also believe that the European Union and its member States cannot create a consistent energy policy with a view to sustainable development without greater and more resolute R and D work in the energy field (part 5), nor without new and ambitious international action to deal with the energy-climate issue (part 6)

    La compression de l'hydrogene est une etape incontournable de son utilisation dans l'industrie actuelle et dans les nouvelles applications energetiques de l'hydrogene (stockage stationnaire et transport). Les compresseurs mecaniques traditionnellement utilises posent plusieurs problemes d'ingenierie, de securite et de maintenance qui pourraient etre contournes en developpant de nouvelles technologies mieux adaptees a l'hydrogene. Dans cette these, notre objectif est de developper d'un compresseur d'hydrogene base sur les hydrures metalliques pouvant etre connecte a la sortie d'un electrolyseur fonctionnant a basse pression et d'ainsi repondre au besoin de productioncompression d'hydrogene decentralisee. La methodologie du projet comprend plusieurs etapes. Premierement, nous faisons la revue bibliographique des projets impliquant des compresseurs a hydrures metalliques. Deuxiemement, a travers des travaux experimentaux, nous recherchons des hydrures permettant une compression efficace entre 20 et 80°C. Les materiaux sont synthetises par fusion a arc electrique et caracterises sur bancs d'essais d'hydrogenation. La structure de certains materiaux est aussi investiguee par rayons X, methode de B.E.T. et microscopie electronique. Troisiemement, un reacteur d'hydrures est concu de maniere a promouvoir des echanges de chaleur rapides et efficaces. Quatriemement, le prototype et son interface de controle sont construits. Cinquiemement, le compresseur est caracterise pour en evaluer les performances en termes de debit et de capacite. Les resultats obtenus sont presentes dans trois articles publies et dans le chapitre 5 de cette these. Le compresseur (article I) est base sur trois hydrures (LaNi 4.8Sn0.2, LaNi5 et MMNi4.7Al0.3 ). Celui-ci permet d'atteindre un debit de compression de 10 a 20 L d'hydrogene par heure et son efficacite est, estimee a ˜5% par rapport a un compresseur adiabatique ideal. Il a ete demontre que l'efficacite pourrait etre augmentee en utilisant un

    Full Text Available Les activités culturelles produisent des biens et services symboliques, qui jouent un rôle crucial dans les sociétés contemporaines. Support indirect des transferts technologiques et vecteur de transformations sociales, l’échange culturel doit nécessairement être pris en compte dans tout système de coopération en faveur du développement. Depuis 1995, les actions de coopération culturelle euro-méditerranéenne se sont multipliées. Sans soutien financier suffisant, elles s’inscrivent cependant difficilement dans la pérennité. Le renforcement des projets de coopération décentralisée, fondé sur l’ancrage territorial de l’action, la mobilisation des parties prenantes et le développement durable, semble dès lors être une voie à approfondir pour en améliorer l’efficacité.Cultural activities produce symbolic goods and services, which play a crucial role in contemporary societies. Any system of cooperation for development must take into account cultural exchange, as an efficient support of technology transfers, and a vehicle for social change. Since 1995, cultural cooperation in the Mediterranean basin increased. However, without sufficient financial support, this mode of cooperation is hardly sustainable. Strengthening decentralized cooperation projects, based on territorial specificities, stakeholder mobilization and sustainable development, appears to be a way to further improve efficiency.

La soumission de l’activité touristique aux exigences de protection, de conservation et de gestion reproductible de la biodiversité et du patrimoine naturel, dans les aires protégées de la Caraïbe française en particulier, génère des approches, des stratégies et des comportements nouveaux. La démarche écotouristique appelle une gestion participative et intégrée des ressources et des espaces, et constitue un défi pour les opérateurs du tourisme comme pour les acteurs de l’environnement, et une opportunité de "réappropriation" de leur milieu de vie par les populations locales. Il faut alors en clarifier le concept et les implications ; puis en analyser les objectifs et les enjeux dans une perspective de développement durable.Tourism often appears as one a tool for a sustainable development, even if it is not easy to control, in the détriment of island and costal environment heritage, as in French overseas regions.

    Le procede de deverminage, ou Environmental Stress Screening (ESS), est employe principalement dans le domaine de l'electronique pour reduire les mortalites infantiles des produits avant leur livraison. Il utilise usuellement des stimulations environnementales telles que les vibrations ou la temperature produites a l'aide d'equipements conventionnels d'essais qui sont tres couteux et difficiles a implanter. Le but de cette recherche est le developpement d'une nouvelle methode d'excitation vibratoire des plaques de circuits electroniques a moindre cout par l'emploi de l'excitation acoustique. Le projet a mene au developpement d'un vibrateur acoustique pouvant etre utilise lors d'implantations du procede ESS en milieu industriel. L'utilisation de cette nouvelle technologie et des methodes novatrices de personnalisation des spectres ESS proposees dans cette these permettent la precipitation de defaillances latentes presentes dans les produits electroniques de facon efficace et securitaire et ce, a moindre cout par rapport aux technologies concurrentes. La methodologie des travaux presentes dans cette these inclus: (1) La generation acoustique des vibrations sur les circuits; (2) L'analyse modale acoustique des circuits par des methodes a reference unique et a references multiples; (3) La precipitation de defauts latents typiques des circuits electroniques; (4) Une methode d'individualisation des spectres vibratoires tenant compte des caracteristiques structurelles des circuits; (5) La presentation de la configuration de l'equipement acoustique et les resultats d'implantation du procede.

Then, it shows that the different public operators (research laboratories, centres and institutions, public agencies) are weakened by decreasing allocations. Three examples are then studied to show the difficulties of these institutions which have to perform fundamental missions with limited means: IFREMER (in the case of oyster control), INRA (for the development of the biotechnology sector) and IRSN (for the safety of nuclear waste storage)

    Full Text Available Les entreprises sociétalement responsables sont celles qui s’inscrivent dans une logique de développement durable. Leur engagement se matérialise, notamment, par le déploiement de systèmes de gestion respectueux de l’environnement tels que les systèmes de management environnemental (SME. En plus de leur portée écologique, ces derniers ont une visée sociale puisqu’ils permettent d’améliorer les conditions de travail des opérateurs. Toutefois, leur mise en place peut être gênée par ces derniers s’ils ne retrouvent pas leurs intérêts lors de l’instauration d’un tel système. L’objectif de ce texte est d’étayer cette idée à partir de l’étude de cas d’une entreprise tunisienne où l’instauration d’un SME n’a pu aboutir en partie à cause de la résistance du personnel. Dans ce sens, nous appuierons l’idée selon laquelle les pratiques du Développement Durable et de la Responsabilité Sociale de l’Entreprise ne se greffent pas ex abrupto sur une entreprise mais nécessitent certains préalables d’ordre organisationnel pour être mis en place.Socially responsible firms are the ones which act in accordance to sustainable development logic.

The purpose of this study is to shore up this idea by resorting to a case study of a Tunisian firm in which the setting of the environmental management system turned failed in part because of the resistance of the personnel. We will defend the idea that practices of sustainable development and corporate social responsibilities couldn’t be correctly adopted by firms without taking into consideration to some organizational

The primary purpose of this paper is to report on barriers that impede systemic, effective and sustainable technology integration within schools. Even with teacher and administrative support and commitment for THSS, evaluative research indicated minimal change in system capacity as a result of the initiative. Three primary barriers to program sustainability were: 1 schools and school districts did not leverage the opportunity to revisit their existing vision(s, 2 schools and school districts did not use data to make changes, and 3 limited access to technology. Le but de l’initiative « Technology and High School Success (THSS » était d'encourager des stratégies novatrices visant à améliorer le taux d’achèvement des études secondaires dans la province de l’Alberta en utilisant la technologie et un apprentissage centré sur l'élève afin de susciter l'intérêt des élèves. L'objectif principal de cet article est de rendre compte des obstacles entravant l'intégration systémique, efficace et durable de la technologie dans les écoles. La recherche évaluative a révélé des changements minimes dans la capacité systémique à la suite de l'initiative, et ce, malgré l’appui et l’engagement des enseignants et des administrateurs envers le THSS. Les trois obstacles principaux à la viabilité du programme sont les suivants: 1 les écoles et les districts scolaires n'ont pas profité de l’occasion pour revoir leur(s vision(s, 2 les écoles et les districts scolaires n'ont pas utilisé les données pour effectuer des changements, et 3 l'accès limité à la technologie.

    L'endommagement par fatigue des materiaux est un probleme courant dans de nombreux domaines, dont celui de l'aeronautique. Afin de prevenir la rupture par fatigue des materiaux il est necessaire de determiner leur duree de vie en fatigue. Malheureusement, dues aux nombreuses heterogeneites presentes, la duree de vie en fatigue peut fortement varier entre deux pieces identiques faites dans le meme materiau ayant subi les memes traitements. Il est donc necessaire de considerer ces heterogeneites dans nos modeles afin d'avoir une meilleure estimation de la duree de vie des materiaux. Comme premiere etape vers une meilleure consideration des heterogeneites dans nos modeles, une etude en elasticite lineaire de l'influence des orientations cristallographiques sur les champs de deformations et de contraintes dans un polycristal a ete realisee a l'aide de la methode des elements finis. Des correlations ont pu etre etablies a partir des resultats obtenus, et un modele analytique en elasticite lineaire prenant en compte les distributions d'orientations cristallographiques et les effets de voisinage a pu etre developpe. Ce modele repose sur les bases des modeles d'homogeneisation classique, comme le schema auto-coherent, et reprend aussi les principes de voisinage des automates cellulaires. En prenant pour reference les resultats des analyses elements finis, le modele analytique ici developpe a montre avoir une precision deux fois plus grande que le modele auto-coherent, quel que soit le materiau etudie.

Pour autant, leur mise en parallèle permet d’éclairer les mécanismes par lesquels s’imposent quelques tendances lourdes de la prise en charge des problèmes publics contemporains. En effet, politique de transport et de déplacements et politique de sécurité routière s’inscrivent dans une perspective commune où qualité de vie, durabilité et sécurité se côtoient, au service d’un environnement sûr et sans nuisance. La safe city deviendrait un modèle à atteindre, une réponse aux désordres urbains, en offrant un environnement attractif pour les classes moyennes et supérieures et en contrôlant les comportements incivils.Nous montrons que la prise en charge de ces deux problèmes publics donne lieu à des rhétoriques et à des pratiques ambiguës dont l’efficacité et la légitimité peuvent être contestées. En ignorant un certain nombre de déterminants macro-sociaux, ces problèmes publics sont dépolitisés. En conséquence, ils donnent lieu à des discours et des pratiques, socialement insoutenables, qui mettent en avant la seule responsabilité individuelle et au sein desquels les rapports sociaux sont euphémisés.The two public policies dealt with in concert in this article do not have much in common from an institutional point of view. And yet, placing them side by side sheds light on the mechanisms through which certain heavy trends have been imposed in handling contemporary public problems. Indeed, transport and travel policy and road safety policy are part of a common outlook in which the quality of life, sustainability and safety come together, serving a safe environment without nuisances. The safe city has become a model to be achieved, a response to urban disorder, providing an attractive environment for the middle and upper classes and controlling uncivil behaviors

    L'objectif principal de cette these est d'identifier les parametres cles pour lier le developpement morphologique de la cime du sapin baumier (Abies balsamea [L.] Mill.) aux patrons de reflectance qu'elle genere sur une image aerienne a haute resolution. La quantite et la distribution spatiale des aiguilles dans le sapin dependent de la structure des branches. Un mecanisme de ramification particulier (la reiteration) ressort comme le parametre cle pour lier l'augmentation de la biomasse foliaire et la forme de la branche. Les reiterats forment des agglomerats de feuillage qui engendrent des inegalites dans les patrons de reflectance de la cime. La reflectance est plus elevee ou il y a une forte concentration de reiterats (maximum local). On demontre que le developpement du sapin baumier se mesure au moyen de l'analyse des maxima locaux de la cime sur une image. La biomasse de l'arbre se mesure par la teledetection et l'analyse des patrons de reflectance de la cime, c'est-a-dire la mesure du niveau de reiteration par le decompte des maxima locaux de la cime. Cette etude demontre qu'il est possible de proceder a l'inventaire du volume de bois d'un peuplement par la teledetection de l'architecture des arbres.

Pour y parvenir, elle elabore un modele pedagogique pouvant se situer dans le cadre theorique de la vision reflexive emergeant presentement en education relative a l'environnement (ERE). Provenant du champ d'etude de la systemique, la methodologie des systemes souples (MSS) s'avere compatible avec le cadre de la reflexivite qui est emergent. Un modele pedagogique preliminaire fut ainsi etabli en transposant et en adaptant plusieurs des principes et des constituantes de la MSS au domaine de l'ERE. Ce modele, s'appuyant sur une strategie de recherche-action, a ete ensuite mis a l'essai aupres d'enseignants du secondaire en formation au Botswana, dans le cadre de leurs activites parascolaires. Cette recherche-developpement de type participatif s'appuie sur une analyse qualitative. Durant sa mise a l'essai, le modele preliminaire a subi plusieurs modifications generees entre autres par les interactions entre les participants et le facilitateur; ces modifications suggerent fortement une prise en charge par les participants de la demarche d'investigation, condition essentielle pour le developpement de competences de resolution de problemes environnementaux. Durant la demarche de resolution du probleme, des competences relatives a l'acquisition de connaissances sur la situation investiguee et a l'action environnementale ont ete sollicitees de maniere repetee.

    Full Text Available Après avoir rappelé le contexte de mutation que connaît actuellement le secteur agricole, nous nous interrogeons sur la place du travail dans la fabrication d’une agriculture durable. Dans cette perspective, nous soulignons trois types d’enjeux. Le premier est relatif à l’objectivation des liens travail-santé. En effet, les conditions de travail se dégradent dans le secteur et celui-ci génère de l’exclusion. Et il est loin d’être attractif. Le second renvoie au lien entre conception et travail. L’agriculture actuelle n’est pas soutenable. Et les pratiques productives des agriculteurs sont en pleine mutation. Mais encore faut-il que ces techniques soient actionnables dans le travail. Nous désignons donc trois voies à la prise en compte du travail dans la conception. Le troisième enjeu est relatif au vivre ensemble. Le développement durable pose en effet très profondément la question d’un futur à faire advenir collectivement. Nous considérons alors cette dimension politique comme un « projet », en posant la question de la prise en compte des projets des agriculteurs dans la définition des visées du développement durable.This paper is focused on work in the making of a sustainable agriculture. We emphasize three types of issue. The first one is related to the objectification of occupational health. Agriculture is a tough sector, which produces exclusion and which is far from attractive. The second is related to design. Farming today is not sustainable, and technical systems need to be designed. But the changes need to be actionable at work. So we present three ways needed in order to think out the workers’ activity during the design process. The third issue is related to Policy: sustainable development is also a future to bring together.

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

  8. Developpement energetique par modelisation et intelligence territoriale: Un outil de prise de decision participative pour le developpement durable des projets eoliens

    Science.gov (United States)

    Vazquez Rascon, Maria de Lourdes

    This thesis focuses on the implementation of a participatory and transparent decision making tool about the wind farm projects. This tool is based on an (argumentative) framework that reflects the stakeholder's values systems involved in these projects and it employs two multicriteria methods: the multicriteria decision aide and the participatory geographical information systems, making it possible to represent this value systems by criteria and indicators to be evaluated. The stakeholder's values systems will allow the inclusion of environmental, economic and social-cultural aspects of wind energy projects and, thus, a sustainable development wind projects vision. This vision will be analyzed using the 16 sustainable principles included in the Quebec's Sustainable Development Act. Four specific objectives have been instrumented to favor a logical completion work, and to ensure the development of a successfultool : designing a methodology to couple the MCDA and participatory GIS, testing the developed methodology by a case study, making a robustness analysis to address strategic issues and analyzing the strengths, weaknesses, opportunities and threads of the developed methodology. Achieving the first goal allowed us to obtain a decision-making tool called Territorial Intelligence Modeling for Energy Development (TIMED approach). The TIMED approach is visually represented by a figure expressing the idea of a co-construction decision and where ail stakeholders are the focus of this methodology. TIMED is composed of four modules: Multi-Criteria decision analysis, participatory geographic Information systems, active involvement of the stakeholders and scientific knowledge/local knowledge. The integration of these four modules allows for the analysis of different implementation scenarios of wind turbines in order to choose the best one based on a participatory and transparent decision-making process that takes into account stakeholders' concerns. The second objective enabled the testing of TIMED in an ex-post experience of a wind farm in operation since 2006. In this test, II people participated representing four stakeholder' categories: the private sector, the public sector, experts and civil society. This test allowed us to analyze the current situation in which wind projects are currently developed in Quebec. The concerns of some stakeholders regarding situations that are not considered in the current context were explored through a third goal. This third objective allowed us to make simulations taking into account the assumptions of strategic levels. Examples of the strategic level are the communication tools used to approach the host community and the park property type. Finally, the fourth objective, a SWOT analysis with the participation of eight experts, allowed us to verify the extent to which TIMED approach succeeded in constructing four fields for participatory decision-making: physical, intellectual, emotional and procedural. From these facts, 116 strengths, 28 weaknesses, 32 constraints and 54 opportunities were identified. Contributions, applications, limitations and extensions of this research are based on giving a participatory decision-making methodology taking into account socio-cultural, environmental and economic variables; making reflection sessions on a wind farm in operation; acquiring MCDA knowledge for participants involved in testing the proposed methodology; taking into account the physical, intellectual, emotional and procedural spaces to al1iculate a participatory decision; using the proposed methodology in renewable energy sources other than wind; the need to an interdisciplinary team for the methodology application; access to quality data; access to information technologies; the right to public participation; the neutrality of experts; the relationships between experts and non-experts; cultural constraints; improvement of designed indicators; the implementation of a Web platform for participatory decision-making and writing a manual on the use of the developed methodology. Keywords: wind farm, multicriteria decision, geographic information systems, TIMED approach, sustainable wind energy projects development, renewable energy, social participation, robustness concern, SWOT analysis.

    This thesis, a collaborative effort between Ecole de technologie superieure and ArcelorMittal Company, presents the development of a methodology for monitoring and quality control of multivariable industrial production processes. This innovation research mandate was developed at ArcelorMittal Exploitation Miniere (AMEM) pellet plant in Port-Cartier (Quebec, Canada). With this undertaking, ArcelorMittal is striving to maintain its world class level of excellence and continues to pursue initiatives that can augment its competitive advantage worldwide. The plant's gravimetric classification process was retained as a prototype and development laboratory due to its effect on the company's competitiveness and its impact on subsequent steps leading to final production of iron oxide pellets. Concretely, the development of this expertise in process control and in situ monitoring will establish a firm basic knowledge in the fields of complex system physical modeling, data reconciliation, statistical observers, multivariate command and quality control using real-time monitoring of the desirability function. The hydraulic classifier is mathematically modeled. Using planned disturbances on the production line, an identification procedure was established to provide empirical estimations of the model's structural parameters. A new sampling campaign and a previously unpublished data collection and consolidation policy were implemented plant-wide. Access to these invaluable data sources has enabled the establishment of new thresholds that govern the production process and its control. Finally, as a substitute for the traditional quality control process, we have implemented a new strategy based on the use of the desirability function. Our innovation is not in using this Finally, as a substitute for the traditional quality control process, we have implemented a new strategy based on the use of the desirability function. Our innovation is not in using this function as an indicator of overall (economic) satisfaction in the production process, but rather in proposing it as an "observer" of the system's state. The first implementation steps have already demonstrated the method's feasibility as well as other numerous industrial impacts on production processes within the company. Namely, the emergence of the economical aspect as a strategic variable that assures better governance of production processes where quality variables present strategic issues.

    The United Nations organisation and nuclear energy rose simultaneously, in 1945, to occupy an important place in the public eye. The spiritual succession of the League of Nations which had foundered during the war was taken up by the new organisation which sought to implant its political ideal in a more tangible reality, so that it might thereby be inspired by concrete and substantial objectives. This is one of the reasons for the existence of the dozen specialized agencies created by the family of the United Nations and dealing with Health, Culture, Agriculture, Finance, etc. Nuclear energy is one of these techniques. Becoming suddenly an important power factor and exploiting for itself the prestige of Science, it became the favorite domain for the growth of this new spirit, as much in its universal form in 1945 as in its more regional form which it was later to adopt. The achievements are numerous and of varying importance; they deserve te be studied carefully. (author) [French] L'organisation des Nations Unies et le nucleaire ont ete places simultanement, en 1945, au premier plan de la scene mondiale.

    Seal durability is critical to achieving the 2010 DOE operational life goals for both stationary and transportation PEM fuel cell stacks. The seal material must be chemically and mechanically stable in an environment consisting of aggressive operating temperatures, humidified gases, and acidic membranes. The seal must also be producible at low cost. Currentlyused seal materials do not meet all these requirements. This project developed and demonstrated a high consistency hydrocarbon rubber seal material that was able to meet the DOE technical and cost targets. Significant emphasis was placed on characterization of the material and full scale molding demonstrations.

    Full Text Available The paper deals with those infrastructures by which world society, under the pressure ofdemographic explosion, self-survives. The main threatening comes not from terrorist attacks, but fromthe great natural catastrophes and global climate change. It’s not for the first time in history when suchmeasures of self-protection are built up. First objective of this paper is to present the background fordurability analysis. Then, with the aid of these mathematical tools the absolute durability of three linearmodels, typical for critical infrastructures, are successively calculated. In order to enhance the durabilityof critical infrastructures the solution based on redundancies is chosen. Five types of connection theredundancies for each of the three models are considered. Three topological schemes for connecting theredundancies are adopted: locally, by twining and globally. Absolute values of durability in all fifteenmodels with redundancies are further calculated. Then, the relative performances of enhanced durabilityin the same fifteen models, compared with the three original models, considered as references, areanalysed. The relative costs of the same fifteen models and in similar topologic conditions are furtheranalysed. By dividing the performance with cost the relative profitableness of each model is obtained.Finally, the three initial models, each reshaped with redundancies in three selective modes, arecompared from the perspective of their relative profitableness. The outcomes of this paper are original.They are of practical interests in planning the maintenance programs and checking the plausibility ofproposed interventions according to the clause 7.4 of ISO 13822:2001

    How to implement the sustainable development? More than 15 years after the Rio conference, the question is still pending, renewed by the intense mobilization of non-governmental actors, organizations, companies, or local communities. Observing the inadequacy of the present day governance system is not sufficient and it is advisable to identify among the numerous dynamics in progress, the beginnings of a new governance. The sustainable development governance is the theme of the 2009 issue of 'the Earth at a glance' book with the ambition to contribute to the reflexion about the present day governance system and its desirable evolutions. Content: the 2008 events status and the schedule of the main 2009 meetings; the 2009 world sustainable development governance: a system to the sustainable development test, dynamics of a changing world, sustainably managing complexity; the sustainable development benchmarks: maps, tables, chronologies, economic, social and environmental syntheses for an original mapping of sustainable development in the world.

À ce titre, il est nécessaire de trouver des instruments juridiques, politiques ou économiques susceptibles de gérer cette « ressource-paysage » sur le long terme. Le gouvernement suisse a introduit récemment l’instrument des parcs naturels régionaux, organisés selon le modèle français, dans sa législation de protection de la nature et du paysage. Une mise en regard des nouveaux parcs avec des structures de gestion beaucoup plus anciennes, les bourgeoisies et les corporations, permet de mettre en évidence les forces et les faiblesses de chacun de ces instruments dans leur contribution à résoudre les rivalités d’usage entre acteurs utilisant ou influençant la ressource paysage.

The examination of the new parks from the perspective of much older management structures, i.e. the civic municipalities (bourgeoisies and corporations, makes it possible to demonstrate the strengths and weaknesses of each of these instruments in their contribution to the resolution of use rivalries between actors who use or influence the resource landscape.

Cet article analyse les principaux éléments d’un processus d’aménagement qui encourage le développement des zones de production agricole dans les quartiers de Xochimilco-Tlahuac, à Mexico. L’expérience a été conceptualisée en 2008 avec l’intégration de données issues du travail sur le terrain, d’entretiens, de techniques ethnographiques et de la géomatique, afin d’intervenir dans les politiques et les activités stratégiques. L’aspect positif de ce travail est qu’il met en avant l’idée que le soutien à l’agriculture urbaine, par les autorités de district ou métropolitaines, afin de traiter les divers problèmes inscrits au calendrier de développement de la ville, est essentielle du point de vue de l'aménagement stratégique et de sa mise en œuvre.

    This thesis aims to appraise the relevance of using an hybrid top-down / bottom-up approach to evaluate mining projects in the perspective of sustainable development. With the advent of corporate social responsibility and sustainable development concepts, new social expectations have appeared towards companies that go beyond a sole requirement of profit earning capacity. If companies do not answer to these expectations, they risk to lose their social legitimacy. Traditionally associated with social, environmental, economical and political impacts and risks, mining activity is particularly concerned by these new issues. Whereas mineral resources needs have never been so high, mining companies are now expected to limit their negative effects and to take into account their different audiences' expectations in order to define, together, the terms of their social license to operate. Considering the diversity of issues, scales, actors and contexts, the challenge is real and necessitates tools to better understand issues and to structure dialogues. Based on the Uranium mines of Arlit (Niger) case study, this work shows that associating participatory approaches to structuration tools and literature propositions, appears as an efficient formula to better organize issues diversity and to build a structured dialogue between mining companies and their stakeholders. First Part aims to present the theoretical, institutional and sectorial contexts of the thesis. Second Part exposes work and results of the evaluation carried out in Niger. And, Third Part, shows the conclusions that can be derived from this work and presents a proposal for an evaluation framework, potentially applicable to other mining sites. (author)

    La presente these s'inscrit dans le cadre de la modelisation mathematique des ecoulements a plasmas thermiques inertes et reactifs. Elle vise plus precisement a combler les lacunes des modeles existants en portant une attention particuliere aux phenomenes de transport multicomposant et a la prediction des transformations chimiques. Pour repondre a ces attentes et ainsi poursuivre le developpement dans ce domaine, un modele global a ete developpe. Il combine la resolution d'equations conservatives pour la masse, l'energie et le momentum. La generation d'un plasma inductif (h.f ) y est traitee au moyen d'equations representant les champs electromagnetiques. La nucleation et la croissance de poudres ultrafines sont incluses dans le modele via l'analyse des principaux moments de la distribution des tailles de particules. Enfin, tous les phenomenes physico-chimiques d'importance dans un milieu comme les plasmas thermiques, de meme que lem interactions, sont consideres. Le modele est applique ici a l'analyse de trois problematiques differentes et complementaires. La premiere concerne l'etude du melange gazeux d'un jet froid (He, N 2 ou O2), injecte au coeur d'une decharge d'argon/hydrogene ou d'argon/oxygene. La comparaison des predictions du modele avec des mesures experimentales obtenues par une sonde enthalpique permet une validation partielle de ce dernier. La deuxieme problematique a trait a l'etude numerique de la pyrolyse du methane en reacteur a plasma h.f. Elle met en evidence les difficultes de convergence de la methode numerique lorsque appliquee a la resolution d'ecoulements reactifs a haute temperature. Finalement, le dernier sujet aborde dans cette these, soit l'analyse systematique des principales conditions d'operation d'un reacteur h.f utilise pour la synthese reactive de poudres ultrafines de silicium, engage tous les elements theoriques du modele.

The behavior of these models depends heavily on whether durable goods are present and whether these goods have sticky prices. If long-lived durables have sticky prices, then even small durables sectors can cause the model to behave as though most prices were sticky. Conversely, if durable goods prices are flexible then the model exhibits unwelcome behavio...

Dans les pays du tiers monde, et l’Algérie en fait partie, « l’appropriation » du développement durable semble s’installer peu à peu et selon un processus qui semble jusque là flou et ambigu. Nous nous sommes intéressés à ce sujet pour apporter un éclairage sur l’appropriabilité des acteurs à l’échelon local, là où la politique suivie fait sens.

The starting p accident has been especially studied both for low-flux piles where a compromise is necessary between the response time of the safety appliances and the statistical fluctuations and for high lux piles where xenon poisoning has an effect on the lower limit of the velocity of reactivity liberation. The desirability has been stressed of automation as a safety factor in atomic pile control. The details required for an understanding of the diagrams of the apparatus are given.

Tous deux désigneraient ces projets d’urbanisme ayant des objectifs environnementaux, sociaux et économiques ambitieux qui se multiplient en France depuis quelques années. Toutefois, dans la pratique, cette synonymie est loin de faire l’unanimité. Sont-ce des quartiers durables, des éco-quartiers ou les deux ? C’est sur cette question de vocabulaire que cet article souhaite se pencher alors même que l’objet qu’ils sont sensés décrire reste lui-même encore à définir précisément. Ceci en axant particulièrement cette interrogation sur la pertinence de l’utilisation de l’expression d’éco-quartier pour désigner ces nouveaux morceaux de ville créés dans un nouveau contexte de réflexion environnementale et humaine. Nous partirons pour cela des diverses utilisations qui en sont faites en tenant compte du contexte matériel, théorique et temporel, dans lequel ces nouveaux éléments de l’urbanisme s’insèrent. Nous verrons également que l’utilisation qui en est faite résonne au delà d’une simple question sémantique.

    Cette these presente les resultats d'une etude sur le mouvement de l'air et les transferts thermiques et massiques dans les arenas en regime transitoire et en 3D. Pour la partie aeraulique, il a ete question de developper un modele base sur la methode zonale qui permet de calculer les debits de l'air (dus a la ventilation et aux gradients de temperature) et de l'humidite entre les differentes zones du batiment et de determiner l'age de l'air dans chacune des zones. Pour la partie thermique, un modele de calcul du rayonnement entre les surfaces interieures du batiment qui a ete couple a TRNSYS afin de calculer sur une base annuelle les charges de chauffage et de refrigeration; ces dernieres tiennent compte des transferts radiatif et convectif, de la chaleur latente due a la condensation de l'humidite sur la glace et du surfacage. Le document presente est constitue de 7 chapitres qui peuvent etre resumes comme suit: Les chapitres 1, 2 et 3 sont consacres respectivement: a l'introduction generale, a la revue bibliographique et a la description du batiment modelise. Le chapitre 4 decrit l'approche developpee et la contribution importante qui y est apportee. Il presente l'utilisation de la methode zonale comme une alternative pratique aux methodes CFD car elle permet de realiser des simulations dynamiques sur une annee avec des temps de simulation tres courts et une precision acceptable. Il s'agit d'une approche intermediaire entre les modeles CFD et les modeles a un noeud d'air (considerant la temperature homogene dans un local). Le chapitre 5 est consacre a la methode de resolution numerique. L'outil de simulation a ete developpe en utilisant l'interface du logiciel TRNSYS: Le type 56 de ce logiciel a ete adopte comme modele energetique tandis que les autres modeles ont ete developpes et programmes en utilisant le logiciel MATLAB.

    Full Text Available The paper describes a research based on the use of the software BIM (Building Information Modeling which is associated with an experimental procedure of the evaluation of durability and the life cycle based on FMEA (Failure Mode and Effects Analysis, one of the methods for durability assessment indicated by the ISO 15686-1 standard. The study shows the methodology and develops a case study on the refurbishment of an old building and discusses its outcome. The experiment on one side illustrates the utility of the analytical approach of FMEA and on the other side the difficulty to use different data and information to be considered in the durability evaluation carried out by the designer  based on the expert assessment. The role of the experts is to design a model and to assess the criticality of each event and to define the relationship between the causes and effects on building elements function. The designer has to define the environmental conditions of the site, the specifications of the material used, the skills of workmanship. The study has shown a quite realistic outcome and significant indications for the designer. Such a result suggests the development of the research.

  10. Developpement D'un Modele Climatique Regional: Fizr Simulation des Conditions de Janvier de la Cote Ouest Nord Americaine

    1995-11-01

    Le sujet de cette these concerne la modelisation numerique du climat regional. L'objectif principal de l'exercice est de developper un modele climatique regional ayant les capacites de simuler des phenomenes de meso-echelle spatiale. Notre domaine d'etude se situe sur la Cote Ouest nord americaine. Ce dernier a retenu notre attention a cause de la complexite du relief et de son controle sur le climat. Les raisons qui motivent cette etude sont multiples: d'une part, nous ne pouvons pas augmenter, en pratique, la faible resolution spatiale des modeles de la circulation generale de l'atmosphere (MCG) sans augmenter a outrance les couts d'integration et, d'autre part, la gestion de l'environnement exige de plus en plus de donnees climatiques regionales determinees avec une meilleure resolution spatiale. Jusqu'alors, les MCG constituaient les modeles les plus estimes pour leurs aptitudes a simuler le climat ainsi que les changements climatiques mondiaux. Toutefois, les phenomenes climatiques de fine echelle echappent encore aux MCG a cause de leur faible resolution spatiale. De plus, les repercussions socio-economiques des modifications possibles des climats sont etroitement liees a des phenomenes imperceptibles par les MCG actuels. Afin de circonvenir certains problemes inherents a la resolution, une approche pratique vise a prendre un domaine spatial limite d'un MCG et a y imbriquer un autre modele numerique possedant, lui, un maillage de haute resolution spatiale. Ce processus d'imbrication implique alors une nouvelle simulation numerique. Cette "retro-simulation" est guidee dans le domaine restreint a partir de pieces d'informations fournies par le MCG et forcee par des mecanismes pris en charge uniquement par le modele imbrique. Ainsi, afin de raffiner la precision spatiale des previsions climatiques de grande echelle, nous developpons ici un modele numerique appele FIZR, permettant d'obtenir de l'information climatique regionale valide a la fine echelle spatiale

  11. Durability of radon remedial actions

    1997-10-01

    In the UK, approximately 3600 householders are believed to have taken action to reduce high radon concentrations in their homes. In 1993 a number of those householders who had taken successful remedial actions were invited to participate in a study of durability of radon remedial actions. This involved the radon concentration being remeasured annually. Results for 26 such homes where a complete set of data are available and a further 32 with incomplete data are discussed here. All remedial actions were shown to remain durable during a period of 5 years. The largest variation in effectiveness was found in houses with natural ventilation of the underfloor void. The failure rate for all remedial measures was found to be 4.0% per annum, but in most cases the problems were noticed by the householder and corrected. The frequency of failures which were not noticed until a remeasurement was carried out was 0.4% per annum. (Author).

    Full Text Available La politique de la ville en France valorise une approche stratégique multiforme des difficultés urbaines, dans une démarche de participation des habitants. La similitude de ses objectifs avec ceux du développement durable est frappante. Il apparaît dès lors pertinent d’engager notre réflexion sur la politique de la ville comme une stratégie de développement durable des quartiers en difficultés. Nous proposons ainsi à travers cet article un essai de définition du quartier en développement durable, tant dans son concept que dans sa mise en œuvre, en nous basant d’une part sur l’analyse de la démarche de participation dans la politique de renouvellement urbain en France, et d’autre part sur la représentation du territoire comme un écosystème.French urban policy is aimed at implementing a transversal understanding of urban problematics using a participative approach. In that sense its objectives are very much interconnected with those of sustainable development. We can therefore consider urban governance policies as strategies supposely focused on the sustainable development of deprived neighborhoods. Through this article, we intend to define what the sustainable development means at the scale of a neighborhood i.e. what are its objectives and how to implement it. We firstly analyse the participatory process in the French urban policy. Second, we engage our reflexion on the ecosystemic understanding of a sustainably developing neighbourhood.

    Progress in the field of seismic qualification and design methods made these last few years allows physical phenomena actually in play to be better considered, while cutting down the conservatism associated with some simplified design methods. So following the change in methods and developing the most advantageous ones among them contributes to the process of the seismic margins assessment and the preparation of new design tools for future series. In this paper, the main developments and improvements in methods which have been made these last two years in the Code Aster, in order to improve seismic calculation methods and seismic margin assessment are presented. The first development relates to making the MISS3D soil structure interaction code available, thanks to an interface made with the Code Aster. The second relates to the possibility of making modal basis time calculations on multi-supported structures by considering local non linearities like impact, friction or squeeze fluid forces. Recent developments in random dynamics and postprocessing devoted to earthquake designs are then mentioned. Three applications of these developments are then ut forward. The first application relates to a test case for soil structure interaction design using MISS3D-Aster coupling. The second is a test case for a multi-supported structure. The last application, more for manufacturing, refers to seismic qualification of Main Live Steam stop valves. First results of the independent validation of the Code Aster seismic design functionalities, which provide and improve the quality of software, are also recalled. (authors). 11 refs.

    2007-07-01

    The present day economical context is favourable to the development of renewable energy sources: high fossil fuel prices, public awareness about environmental problems, etc. The incentive measures implemented by public authorities (regulation, repurchase tariff, tax credits etc.) have permitted to overcome the competitiveness handicap. This favorable framework should last long thanks to the strong support of the European Union. This market study deals with the photovoltaic conversion industry and answers the following questions: what is the world market growth of photovoltaic conversion? What are the most flourishing applications? What are the best oriented markets? How heavy is the world market? What is the degree of competitiveness of this industry? What is the development potential of this market? Who are the best-positioned groups to profit of it? What is the progress of the sector structuration? What is the future of pure players? (J.S.)

  18. Developpement d'algorithmes paralleles pour la simulation d'ecoulements de fluides dans les milieux poreux

    Science.gov (United States)

    Vidal, David Jean-Emmanuel

    Two different parallel lattice Boltzmann (LBM) algorithms have been devised for the simulation of flow through complex porous media. They are based on memory efficient LBM algorithms, namely the one-lattice and shift algorithms, combined with vector data structure, even fluid node vector partitioning domain decomposition and efficient data transfer layouts. The shift implementation also includes a single unit relaxation scheme that allows additional memory savings, but limits its validity to Newtonian fluids. They both provide high parallel performance by balancing the workload among the processors and reducing the amount of data that need to be transferred, and reduce significantly the memory usage as compared to previous parallel LBM codes presented in the literature. Theoretical parallel performance and memory usage models developed show that they also offer a good evolutivity and efficiencies as high as 79% for simulations made of several billions of fluid nodes on 128 processors are reported. The application of one of these algorithms for the simulation of flow through compressed packings made of highly polydisperse spheres has demonstrated the remarkable precision and efficiency of the algorithm proposed. As a result, a modified Carman-Kozeny correlation taking into account the compression level and the particle polydispersity has been formulated.

    The durability of polymer electrolyte membrane (PEM) fuel cells is a major barrier to the commercialization of these systems for stationary and transportation power applications. By investigating cell component degradation modes and defining the fundamental degradation mechanisms of components and component interactions, new materials can be designed to improve durability. To achieve a deeper understanding of PEM fuel cell durability and component degradation mechanisms, we utilize a multi-institutional and multi-disciplinary team with significant experience investigating these phenomena.

    Full Text Available La gestion des déchets municipaux a souffert pour longtemps de l'absence d'un cadre réglementaire et institutionnel spécifique. Cette situation s'est traduite par une gestion anarchique qui a générée de problèmes structurels et a contribué à la dégradation de l'état de l'environnement. En effet, la loi 28-00 adoptée au Maroc en 2006 arrête les règles et les principes fondamentaux qui se rapportent à la gestion des déchets et à leur élimination et permet d'asseoir une gestion rationnelle, moderne et efficace du secteur, respectueuse des exigences de développement durable et de la protection de l'environnement. Néanmoins, les objectifs du développement durable liés au droit des déchets municipaux sont confrontés à des obstacles qui limitent leur réalisation. Dans cet article, nous essayons, dans un premier lieu, de passer au crible du développement durable le droit des déchets municipaux, pour passer, en deuxième lieu, à dresser l’état de lieux de son effectivité.

    Full Text Available Le transport génère des externalités négatives – notamment environnementales – largement reconnues et dénoncées. Aussi, la référence à la durabilité désormais incontournable dans de nombreux domaines de l’action publique, s’étend inévitablement au transport via la notion de transport durable. C’est notamment en matière de fret que les enjeux de durabilité semblent les plus importants : le taux de croissance du transport des marchandises est en effet plus élevé que celui des passagers et le déséquilibre des parts modales s’y creuse davantage, en défaveur des modes les moins polluants. Dans le transport de fret, c’est la politique européenne des transports qui exerce aujourd'hui une influence déterminante à la fois sur la conduite de la politique française (à toutes les échelles et sur les comportements de la quasi-totalité des acteurs et des opérateurs qui interviennent dans le domaine des transports en France. C’est donc sur le segment des flux de marchandises que notre papier traitera de la traduction européenne des principes fondateurs de la notion de transport durable.Transportation generates negative externalities (especially environmental ones widely known and denounced. Thereby, the reference to sustainability, now incontrovertible in many areas of the public action, reaches transportation via the concept of sustainable transportation. The most important need in sustainability is on freight transportation : carriage growth rate is higher than passenger transportation, and the unevenness between the modal parts is in favour of the most polluting. On freight transportation, the European Union policy exercises a determining opinion, both on the French public policies (at every scale and on most of the actors stepping in the transportation domain in France. The topic of this paper is on the segment of carriage flux and on the European translation of the founding principles of sustainable

    Full Text Available A la première question, nous répondrons bien sûr, par l’affirmative puisque tous les pays sont engagés dans une nouvelle approche du développement qui ne consiste pas seulement à produire le plus de biens et au moindre coût, afin de vendre beaucoup et réaliser de grands profits. C’était la vision en vigueur dans toutes les techniques de gestion mais on s’est rendu compte que cette production, supposée au moindre coût, était en fait, souvent d’un coût exorbitant, relativement aux dégâts occasionnés dans l’environnement et dans les nuisances occasionnées à la santé de l’homme et à sa tranquillité. Il est temps d’inclure d’autres variables dans le calcul du prix de revient tout en revoyant certaines techniques de production trop salissantes, dangereuses ou grosses consommatrices d’énergie. Nous répondrons aussi par la négative quand on pense qu’au niveau micro économique, les comportements sont édictés par les satisfactions immédiates et les maximisations des profits. Ces comportements qui ne s’intéressent qu’aux résultats à court terme, ne s’intègrent pas facilement dans les plans de développement visant les équilibres macro économiques à long terme.A la deuxième question, nous dirons qu’il y a effectivement des indicateurs pour tester les niveaux de qualité dans l’éducation, la santé, les ressources naturelles... et les gains tirés au niveau social mais les calculs économiques qui déterminent la rentabilité des projets, les profits espérés, les risques financiers encourus ne sont pas toujours en rapport avec les efforts pour réaliser le développement durable qui, eux dépassent la simple notion d’efficacité et de satisfaction. Quand on pense aux générations futures, ce n’est pas seulement en termes de durée dans le temps mais aussi dans la manière d’apprécier les gains espérés.Notre recherche repose sur ces questions qui minent bien des efforts alors qu

    It is estimated that at least 3600 householders in the UK have taken remedial action to reduce radon concentrations found to be above the government Action Level. A study has been carried out on the durability of these remedial actions. It involved annual reassessment of the radon levels in a number of homes. The results for 26 of these homes where data over five years are available show that in general the remedial actions remained effective. The remedy with the largest variation in efficacy was natural ventilation of the underfloor void. The failure rate was found to be 4.0% per annum for all measures, but in the majority of cases the failure was discovered by the householder and rectified. The rate of failures not noticed by the householders was 0.4% per annum. (UK).

    Full Text Available Durability performance of rubberized concrete against abrasion is presented in this paper. Surface depth loss was measured when abrasion load was constantly applied on concrete surface at each 500 interval rotation. Specimen with water-to cement ratio of 0.50 and 0.35 was prepared and tested at 28 days of curing age. In addition, 10% silica fume, SF was added to provide denser concrete and to understand its effectiveness against wear when added with crumb rubber. Results showed that crumb rubber shows good potential in providing abrasion resistance to concrete mix. However, in the case of rubberized concrete with silica fume, abrasion resistance was found to be slightly decreased with compressive strength more than 50N/mm2 due to the lack of low elastic modulus of CR particles to accommodate with denser cement matrix.

    At present, there are three seriously considered options for the disposition of excess weapons plutonium: (1) incorporation, partial burn-up and direct disposal of MOX-fuel; (2) vitrification with defense waste and disposal as glass {open_quotes}logs{close_quotes}; (3) deep borehole disposal. The first two options provide a safeguard due to the high activity of fission products in the irradiated fuel and the defense waste. The latter option has only been examined in a preliminary manner, and the exact form of the plutonium has not been identified. In this paper, we review the potential for the immobilization of plutonium in highly durable crystalline ceramics apatite, pyrochlore, zirconolite, monazite and zircon. Based on available data, we propose zircon as the preferred crystalline ceramic for the permanent disposition of excess weapons plutonium.

    Morocco's national energy policy includes the use of renewable energy sources to lessen its reliance on fossil fuels such as coal and oil. Legislation was recently passed to increase the threshold of electrical power from 10 MW to 50 MW. Solar and wind energy are the most abundant renewable energy resources in the country and are recommended for exploitation on a large scale. Feasibility studies conducted by the Centre de Developpement des Energies Renouvelables have shown that Morocco has enough wind energy to produce electricity on a large scale and interconnect it with the national power grid. Wind energy in the country could also be used for on-site power generation in remote villages or for desalination of seawater, particularly in the southern regions of Morocco which are most affected by drought. Essaouira, Tangier, Tetouan, Tarfaya, Dakhla, Laayoune and Taza were among the regions identified with significant wind resources. The total wind energy potential for Morocco is estimated to be 2,650 GW, while the technical wind energy potential is estimated to be 1,600 GW. Several projects have been realized in the areas of electricity production, interconnection to the national power grid, decentralized rural electrification and eventually the introduction of water pumping. It was concluded that exporting green energy to Europe, via the Morocco-Spain route after the restructuring of Morocco's electricity sector will create a viable market for the medium and long-term. 3 figs.

    Les materiaux composites avances a matrice polymerique lorsqu'utilises dans des applications structurales aerospatiales sont souvent exposes a des temperatures tres elevees durant de courtes periodes de temps. Ces expositions thermiques peuvent affecter de facon significative leurs proprietes mecaniques. Cette degradation des proprietes suite a la surchauffe est un probleme qui souleve de plus en plus d'inquietude au sein de la communaute aerospatiale. On s'interesse tout autant a la caracterisation de l'endommagement resultant de l'exposition thermique qu'a son evaluation non-destructive. Bien que la technique acousto-ultrasonique semble etre une technique d'evaluation non-destructive toute indiquee pour la detection et la caraterisation de l'endommagement thermique dans les composites avances, il semblerait qu'on ne l'ait pas encore exploitee en ce sens. Cette lacune combinee a l'engagement du Ministere canadien de la defense nationale a developper une technique d'evaluation non-destructive in-situ de l'endommagement thermique de structures composites dans certains avions de chasse de la flotte canadienne constituent la motivation majeure de ce projet de recherche. Cette etude evalue la capacite de la technique acousto-ultrasonique a detecter et quantifier l'endommagement subi par un materiau composite suite a une exposition thermique. Pour parvenir a cet objectif, l'approche de cette etude a ete principalement de nature experimentale. Dans ce contexte, une base importante de donnees acousto-ultrasoniques a ete generee sur des materiaux composites vierges et conditionnes dans le but de correler ces donnees a celles issues des essais mecaniques et des analyses micrographiques et fractographiques. L'evaluation acousto-ultrasonique de la degradation thermique a ete realisee sur des echantillons de resine pure et de composite ayant ete expose a divers conditionnements.

La conversion des signaux optiques en signaux electroniques (et vice versa) est couteuse et d'efficacite restreinte. Il est donc necessaire pour les chercheurs de trouver des strategies qui permettraient de transmettre le signal d'un bout a l'autre de la ligne sous forme optique. Deja, des amplificateurs a fibre existent pour repondre au premier probleme; il reste a trouver une maniere tout-optique de prendre des decisions par rapport au signal transmis. L'utilisation de filtres passifs, hautement selectifs en longueur d'onde et inscrits directement dans la fibre optique, est une solution elegante pour repondre a ce second probleme. Les reseaux de Bragg dans la fibre optique correspondent a cette description: nous avons donc decide de les etudier de facon rigoureuse. Nous avons d'abord tente de mieux comprendre la reaction photosensible provoquant l'inscription de ce genre de dispositif dans certaines fibres optiques. Ensuite, une nouvelle methode d'inscription de reseaux de Bragg dans la fibre optique a ete elaboree et caracterisee. Finalement, certaines applications des reseaux que nous avons inscrits ont ete proposees. L'etude de la reaction photosensible a ete faite indirectement, a l'aide de phenomenes provoques par celle -ci: la photoluminescence, l'attenuation photo-induite et les changements d'indice photo-induits. L'observation de ces phenomenes nous a permis de developper un modele sommaire, expliquant en partie la reaction photosensible. Le montage d'ecriture des reseaux de Bragg dans la fibre optique nous a permis d'observer la nature quasi -isotrope du changement d'indice photo-induit. La qualite des reseaux de Bragg inscrits a l'aide de ce montage a ete evaluee. Le montage nous a aussi permis de demontrer que la

    Full Text Available Environment is the external factor that affects the durability of concrete structures. Buildings in different regions with different climates will respond to durability deterioration in different ways. For macroenvironmental regionalization, the dominant factor analysis method of the climatic zonation was applied into the environmental regionalization in this paper. Based on the environmental characteristics in China and the effect of environmental factor on the durability of concrete structure, the proper regionalization indexes are chosen, and the environmental regionalization is made. For microenvironmental regionalization, fuzzy set and rough set theories were used in date mining on discrete measured data, and the weight determination of various factors affecting durability was transformed into evaluation of the significance of attributes among rough sets. The method of durability environmental regionalization is established by analyzing the degree of influence that various factors have on the durability of concrete structures. The result of durability environmental regionalization for concrete structures in Shenzhen city shows that the proposed approach is reasonable.

    Achieving DOE's stated 5000-hr durability goal for light-duty vehicles by 2015 will require MEAs with characteristics that are beyond the current state of the art. Significant effort was placed on developing advanced durable cathode catalysts to arrive at the best possible electrode for high performance and durability, as well as developing manufacturing processes that yield significant cost benefit. Accordingly, the overall goal of this project was to develop and construct advanced MEAs that will improve performance and durability while reducing the cost of PEMFC stacks. The project, led by UTC Power, focused on developing new catalysts/supports and integrating them with existing materials (membranes and gas diffusion layers (GDLs)) using state-of-the-art fabrication methods capable of meeting the durability requirements essential for automotive applications. Specifically, the project work aimed to lower platinum group metals (PGM) loading while increasing performance and durability. Appropriate catalysts and MEA configuration were down-selected that protects the membrane, and the layers were tailored to optimize the movements of reactants and product water through the cell to maximize performance while maintaining durability.

    The issue of major concern with the waste form, such as glass, is its chemical durability, I. e., the resistance to corrosion by aqueous media. A number of standard durability tests have been established for waste glasses, among which the product consistency test was selected as a criterion of HLW glass acceptability for the repository subsequently, a large PCT database has been collected containing over 1000 glasses. Such a database allows the development of models that relate PCT releases to glass is a strong function of composition, these models are used to formulate acceptable glasses in which the waste loading is maximized. Within the composition space of glasses, a distinct threshold appears to exist that separates 'good' glasses, I. e. these which are sufficiently durable, from 'bad' glasses of a low durability. According to Populate al., transition region between durable and less durable glasses lies around 2a m{sup -2} as determined by the 7-day PCT normalized B release. The objective of our research is to clarify the origin of this threshold by exploring the relationship between glass composition, glass structure and chemical durability around the threshold region. Our study is focused on the corrosion behavior of SiO{sub 2} - B{sub 2}O{sub 3} - Na{sub 2}O - Al{sub 2}O{sub 3} - Colleagues composition region. In particular, we try to identify the durability threshold separating durable from nondurable glasses in the composition space. So far we have explored the elemental releases of Na and B measured with the 7-day PCT.

    This final report for the Swiss Federal Office of Energy (SFOE) presents the results of a study made on the possibilities of establishing a system of indicators that allows the monitoring of sustainable development and its effects, as stipulated in the Agenda 21. The report presents the findings of the study on criteria and indicators for sustainability in the energy area. The challenge posed by the synthesis of information from a system of indicators is discussed and four general approaches are proposed, compared and tested for the monitoring of sustainability in the energy area. These include the calculation of a composite index from several indicators, a similar process that uses statistical methods of dimensional reduction, methods for the measurement of productivity loaned from economics and a method for decision-making using multiple criteria. Examples for the four approaches are given and experience gained in their use - partly in other countries and in United Nations agencies - is discussed.

One of these communities, Vale Encantado, whose occupation dates from the mid-eighteenth century, experienced the various production cycles that developed in the area, through logging, farming, livestock production, ornamental plants and black granite mining. To a greater or lesser degree, these production cycles impacted negatively on the native forest. However, simultaneously with this process, the Vale Encantado community has witnessed the implementation of reconstruction and conservation efforts of this fragment of Atlantic Rainforest, through reforestation and the creation of the Tijuca National Park in 1961. Today, through sustainable tourism and the social cuisine program, Vale Encantado has become a benchmark in the process of coexistence, integration and conservation of the local environment, and is the acknowledged "guardian of the forest."Considérée comme une des plus grandes forêts urbaines du monde et la troisième plus grande du Brésil, la Forêt de Tijuca, située dans la Ville de Rio de Janeiro, est face à un grand défi : cohabiter de façon harmonieuse et durable avec les 46 favelas qui l’entourent.

    Bergeron, Dominic

    Le modele de Hubbard bi-dimensionnel (2D) est souvent considere comme le modele minimal pour les supraconducteurs a haute temperature critique a base d'oxyde de cuivre (SCHT). Sur un reseau carre, ce modele possede les phases qui sont communes a tous les SCHT, la phase antiferromagnetique, la phase supraconductrice et la phase dite du pseudogap. Il n'a pas de solution exacte, toutefois, plusieurs methodes approximatives permettent d'etudier ses proprietes de facon numerique. Les proprietes optiques et de transport sont bien connues dans les SCHT et sont donc de bonne candidates pour valider un modele theorique et aider a comprendre mieux la physique de ces materiaux. La presente these porte sur le calcul de ces proprietes pour le modele de Hubbard 2D a couplage faible ou intermediaire. La methode de calcul utilisee est l'approche auto-coherente a deux particules (ACDP), qui est non-perturbative et inclue l'effet des fluctuations de spin et de charge a toutes les longueurs d'onde. La derivation complete de l'expression de la conductivite dans l'approche ACDP est presentee. Cette expression contient ce qu'on appelle les corrections de vertex, qui tiennent compte des correlations entre quasi-particules. Pour rendre possible le calcul numerique de ces corrections, des algorithmes utilisant, entre autres, des transformees de Fourier rapides et des splines cubiques sont developpes. Les calculs sont faits pour le reseau carre avec sauts aux plus proches voisins autour du point critique antiferromagnetique. Aux dopages plus faibles que le point critique, la conductivite optique presente une bosse dans l'infrarouge moyen a basse temperature, tel qu'observe dans plusieurs SCHT. Dans la resistivite en fonction de la temperature, on trouve un comportement isolant dans le pseudogap lorsque les corrections de vertex sont negligees et metallique lorsqu'elles sont prises en compte. Pres du point critique, la resistivite est lineaire en T a basse temperature et devient

    Gamma TiAl was evaluated as a candidate alloy for low-pressure turbine blades in aeroengines. The durability of g-TiAl was studied by examining the effects of impact or fretting on its fatigue strength. Cast-to-size Ti-48Al-2Cr-2Nb was studied in impact testing with different size projectiles at various impact energies as the reference alloy and subsequently fatigue tested. Impacting degraded the residual fatigue life. However, under the ballistic impact conditions studied, it was concluded that the impacts expected in an aeroengine would not result in catastrophic damage, nor would the damage be severe enough to result in a fatigue failure under the anticipated design loads. In addition, other gamma alloys were investigated including another cast-to-size alloy, several cast and machined specimens, and a forged alloy. Within this Ti-48-2-2 family of alloys aluminum content was also varied. The cracking patterns as a result of impacting were documented and correlated with impact variables. The cracking type and severity was reasonably predicted using finite element models. Mean stress affects were also studied on impact-damaged fatigue samples. The fatigue strength was accurately predicted based on the flaw size using a threshold-based, fracture mechanics approach. To study the effects of wear due to potential applications in a blade-disk dovetail arrangement, the machined Ti-47-2-2 alloy was fretted against In-718 using pin-on-disk experiments. Wear mechanisms were documented and compared to those of Ti-6Al-4V. A few fatigue samples were also fretted and subsequently fatigue tested. It was found that under the conditions studied, the fretting was not severe enough to affect the fatigue strength of g-TiAl.

    . Comment reduire les emissions moyennes de CO2 des vehicules particuliers a 120 g/km en 2012 et 95 g/km en 2020 comme le prevoit l’accord conclu entre la Commission Europeenne et les constructeurs europeens ? Cette question a reponses multiples preoccupe a l’heure actuelle l’ensemble du monde automobile. L’electrification des vehicules semble etre une des solutions les plus pertinentes, ce qui pousse les constructeurs a envisager des vehicules hybrides de plus en plus innovants. Cette solution, theoriquement tres interessante, complexifie encore un peu plus les groupes moto-propulseurs des vehicules, ce qui necessite l’utilisation d’outils de simulation adequats pour reduire les couts et les durees de developpement. La simulation systeme, outil deja primordial dans le processus de developpement des moteurs a combustion interne, devient alors incontournable. Pour etudier ce type d’architectures hybrides complexes, et a l’instar des modeles physiques developpes pour le moteur a combustion interne, la simulation systeme doit se doter de modeles predictifs comparables pour les machines electriques. Des leurs specifications, ces modeles doivent integrer certaines contraintes tres exigeantes sur les temps de simulation, contrainte garantissant par la suite une plus large utilisation des simulateurs, notamment pour le developpement et la validation de strategies de controle. L’objectif de ce papier est donc de presenter une methodologie generale de developpement de modeles de machines electriques, modeles ayant pour objectif final d’etre integres dans un simulateur vehicule complet. Cette methodologie met en scene differents types de modelisations (modeles elements finis, modeles de caracterisation, modele de simulation permettant un compromis temps de calcul – precision adequat. Cette methodologie a ete deployee avec succes pour la modelisation d’un moteur synchrone a aimants permanents. A l’issue du processus de modelisation, ce dernier a ete integre

    Dans l'hOpital, le besoin d'un reseau de communication electronique ne cesse de crottre au fur et a mesure de la numerisation des images. Ce reseau local a pour but de relier quelques sources d'images telles la radiologie numerique, la tomodensitometrie, la resonance magnetique nucleaire, l'echographie ultraso-nore etc..., a un systme d'archivage. Des consoles de visualisation interacti-ves peuvent etre utilisees dans les salles d'examens, les bureaux des medecins et les services de soins. Dans un tel systme, trois caracteristiques princi-pales doivent etre prises en compte le debit, la longueur du cable et le nombre de connexions. - Le debit est tr?)s important, en effet, un temps de reponse maxima de quel-ques secondes doit etre garanti pour des images de plusieurs millions d'ele-ments binaires. - La distance entre connexions peut etre de quelques km dans certains grands hopitaux. - Le nombre de connexions au reseau ne depasse jamais quelques dizaines car les sources d'images et les unites de traitement representent des materiels importants, par ailleurs les consoles de visualisation simples peuvent etre groupees en grappe. Toutes ces conditions sont remplies par les transmissions sur fibres optiques. Selon la topologie et la methode d'accNs, deux solutions peuvent etre envisa-gees : - Anneau actif - Etoile active ou passive Enfin, les developpements de Thomson-CSF en composants pour transmissions optiques pour les grands reseaux de tel4distribution nous apportent un support technologique et une production de masse qui diminuera les collts du materiel.

  6. Dental adhesion: mechanism, techniques and durability.

    Manuja, N; Nagpal, R; Pandit, I K

    2012-01-01

    Contemporary dental adhesives show favorable immediate results in terms of bonding effectiveness. However, the durability of resin-dentin bonds is their major problem. It appears that simplification of adhesive techniques is rather detrimental to the long-term stability of resin-tooth interface. The hydrostatic pulpal pressure, the dentinal fluid flow and the increased dentinal wetness in vital dentin can affect the intimate interaction of certain dentin adhesives with dentinal tissue. Bond degradation occurs via water sorption, hydrolysis of ester linkages of methacrylate resins, and activation of endogenous dentin matrix metalloproteinases. The three-step etch-and-rinse adhesives still remain the gold standard in terms of durability. This review discusses the fundamental process of adhesion to enamel and dentin with different adhesive techniques, factors affecting the long-term bonding performance of modern adhesives and addresses the current perspectives for improving bond durability.

    Based on the damage mechanics, the concrete damage grade of relative stable environment in measurable spatial is constructed in this paper, and the concrete damage evolving model and corresponding failure rule is constructed based on the damage grade fore-defined. Therefore, the concrete health status and the residual life-span can be assessed according to the measured damage grade. It is propitious to drive the development of concrete durability assessment and life-span forecast. Its feasibility of concrcte damage process description and health assessment is validated with the example in this paper, in which the damage state is described with the ultrasound velocity attenuation, and the freeze-thaw process is regarded as the concrete durability degradation influencing factor to reflect the concrete durability degradation process.

    Gaudreau, Louis

    Nous presentons dans cette these une etude detaillee du moment magnetique intrinseque de l'electron, i.e. le spin electronique, incluant la manipulation quantique coherente des etats de spin de trois electrons couples. A cette fin, nous utilisons des boites quantiques laterales pour confiner les electrons. Ces nano-structures, d'une grandeur autour de 1 pm, permettent de confiner un nombre precis d'electrons de facon controlee, allant jusqu'a zero electrons. Les developpements technologiques et d'ingeniosite durant la derniere decennie ont permis de coupler trois boites quantiques, ainsi l'interaction entre plusieurs electrons confines peut etre controlee comme par exemple le couplage quantique tunnel et l'interaction d'echange entre les spins de chacun d'entre eux. A l'aide de boites quantiques couplees, il est possible de realiser des experiences dans plusieurs domaines de la physique moderne : les etats up et down du spin des electrons confines peuvent etre utilisees comme etats quantiques binaires (qubits) dans le domaine de l'informatique quantique, la non-localite quantique peut etre testee en separant spatialement deux electrons enchevetres, il est possible de creer des 'courants de spin enchevetres' utiles en spintronique, et bien d'autres. La manipulation coherente des etats de spin du systeme a trois electrons se fait de facon purement electrique grace a des pulses a haute frequence qui permettent d'augmenter le couplage entre les electrons et de faire la mesure de l'etat resultant apres la manipulation. Nous utilisons l'interaction hyperfine entre les spins des electrons et ceux des noyaux du cristal dans lequel ils resident pour creer les rotations quantiques entre les etats, notamment les etats |Q +3/2> et (D+1/2>. Les resultats obtenus indiquent un temps de coherence de l'ordre de 10 ns. Ces experiences demontrent un niveau de controle sans precedant de boites quantiques triples et pavent la voie vers des nano-structures plus sophistiquees dans

    Pollution, noise, accidents, spoilt landscapes, towns and valleys blocked by road traffic are the negative consequences of the development of transportation systems and mobility. Road transport is considered as highly polluting and highly space and energy consuming. This books takes stock of this burning topic for all responsible and political participants in this sector: what are the `external effects` of transports and their evaluation, what can be learnt from the economic approaches, what can be expected in the future and what are our degrees of freedom. The approach used by the author consists in discussing the main questions using a critical review of recent published works. The four main chapters of this book deal successively with: the `external effects` of transports (nuisances, environmental and financial impact, financial compensations, heritage destruction, arbitration..), the evaluation of the `external effects` and its benefit, and the compatibility between our transportation system and the development of our community (risks, policy, technological solutions..).

    2000-06-06

    This talk was presented by the France's State Secretary for Industry to the second Colloquium organized by 'Syndicat des Energies renouvelables'. Boosting the renewable energies is in the center of interest of the Government's energy policy. Indeed, these energies meet fundamental need of the country: an energy of quality, ensured as long term supply, environmental protective, creating employment and available for future generation. Being purely national as origin these energies contribute to the energy independence and security of energy supply. Moreover, these energies are indispensable if the international environment is taken into account, as it remains uncertain still for long time from both physical availability of the energy raw materials and the geopolitical risk standpoints. The gas, for instance, comes mostly from regions unstable politically, and unstable is also the fossil fuel price level. In addition these type of energies contribute beside the nuclear sector to the struggle against greenhouse effect as they are not CO{sub 2} emitters. As known France has assumed at Kyoto Conference the difficult responsibility of maintaining the pollutant emissions by the year 2010 at the level of 1990. The interest for renewable energies as compared to imported fossil energies is yet superior from another point of view, that of the struggle against unemployment, because the content of national labour force is higher in the former case. In 1999 the renewable energy production increased to 28.6 Mtep (million tons of oil equivalents), i.e., 23% and 11% of the country's production and primary energy consumption, respectively. The renewable energies come on the second place in the national energy production after the nuclear sector but rather well in front of gas, oil and coal energies, combined. A number of major events in 1999 are mentioned. EDF promoted 24 projects of wind power areas with 236 MW power. The total power of the projects included in EOLE 2005 Programme amounts up to 360 MW. The objective of installing 500 MW by year 2005 horizon has all chances to be achieved and even surpassed. Other electricity producing installations based on methane from garbage fermentation, burning of domestic refuse or wood, solar energy are mentioned as contributions to the total power production and also to employment. Prospects for future development are presented in the frame of both electricity producing and non-electricity producing options. Finally, the situation of export energy market is shown.

    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.

    The low stability, complicated and expensive fabrication procedures seriously hinder practical applications of superhydrophobic materials. Here we report an extremely simple method for preparing super durable superhydrophobic materials, e.g., textiles and sponges, by dip coating in fluoropolymers (FPs). The morphology, surface chemical composition, mechanical, chemical and environmental stabilities of the superhydrophobic textiles were investigated. The results show how simple the preparation of super durable superhydrophobic textiles can be! The superhydrophobic textiles outperform their natural counterparts and most of the state-of-the-art synthetic superhydrophobic materials in stability. The intensive mechanical abrasion, long time immersion in various liquids and repeated washing have no obvious influence on the superhydrophobicity. Water drops are spherical in shape on the samples and could easily roll off after these harsh stability tests. In addition, this simple dip coating approach is applicable to various synthetic and natural textiles and can be easily scaled up. Furthermore, the results prove that a two-tier roughness is helpful but not essential with regard to the creation of super durable superhydrophobic textiles. The combination of microscale roughness of textiles and materials with very low surface tension is enough to form super durable superhydrophobic textiles. According to the same procedure, superhydrophobic polyurethane sponges can be prepared, which show high oil absorbency, oil/water separation efficiency and stability. Copyright © 2014 Elsevier Inc.

    Technical challenges limit the commercialization of polymer electrolyte membrane fuel cells (PEM) for use in stationary applications and transport. These include: on-board storage and infrastructure for hydrogen fuel as well as the fuel cell system itself; high costs; and, durability under a wide range of operational conditions. Durability is defined as the maximum service life of a fuel cell system with no more than 10 per cent loss in efficiency at the end of life. This paper presented a literature review and analysis in order to provide a unified definition of PEM fuel cell service life when operated at either steady state or dynamic load conditions. The paper presented an analysis of different operating conditions and the dependence of PEM fuel cell durability on the operating condition. The paper also reviewed durability studies of the different components of a PEM fuel cell, and also examined various degradation mechanisms. These included: load or thermal cycles; fuel or oxidant starvation; high or low humidification levels; and, reformate or simulated reformed gases as fuels. A relationship between the accelerated service life of a PEM fuel cell and the real service life was then developed. To obtain real service life under normal testing conditions, statistical models based on accelerated service life data were illustrated. It was concluded that the service life of a fuel cell and its components is a function of more than one or two variables. 46 refs., 4 tabs., 3 figs.

  8. DURABLE GLASS FOR THOUSANDS OF YEARS

    Energy Technology Data Exchange (ETDEWEB)

    Jantzen, C.

    2009-12-04

    The durability of natural glasses on geological time scales and ancient glasses for thousands of years is well documented. The necessity to predict the durability of high level nuclear waste (HLW) glasses on extended time scales has led to various thermodynamic and kinetic approaches. Advances in the measurement of medium range order (MRO) in glasses has led to the understanding that the molecular structure of a glass, and thus the glass composition, controls the glass durability by establishing the distribution of ion exchange sites, hydrolysis sites, and the access of water to those sites. During the early stages of glass dissolution, a 'gel' layer resembling a membrane forms through which ions exchange between the glass and the leachant. The hydrated gel layer exhibits acid/base properties which are manifested as the pH dependence of the thickness and nature of the gel layer. The gel layer ages into clay or zeolite minerals by Ostwald ripening. Zeolite mineral assemblages (higher pH and Al{sup 3+} rich glasses) may cause the dissolution rate to increase which is undesirable for long-term performance of glass in the environment. Thermodynamic and structural approaches to the prediction of glass durability are compared versus Ostwald ripening.

Outdoor sites are fully instrumented in terms of monitoring meteorological conditions and solar irradiance. Candidate materials are optically characterized prior to being subjected to exposure in real and simulated weathering environments. Optical durability is quantified by periodically re-measuring hemispherical and specular reflectance as a function of exposure time. By closely monitoring the site- and time-dependent environmental stress conditions experienced by the material samples, site-dependent loss of performance may be quantified. In addition, accelerated exposure testing (AET) of these materials in parallel under laboratory-controlled conditions may permit correlating the outdoor results with AET, and subsequently predicting service lifetimes. Test results to date for a large number of candidate solar reflector materials are presented in this report. Acronyms are defined. Based upon OET and AET results to date, conclusions can be drawn about the optical durability of the candidate reflector materials. The optical durability of thin glass, thick glass, and two metallized polymers can be characterized as excellent. The all-polymeric construction, several of the aluminized reflectors, and a metallized polymer can be characterized as having intermediate durability and require further improvement, testing and evaluation, or both.

    Full Text Available Innovation is the way of life of any institution to profitably sustain its life. It starts with empathy, the ability to reach outside of ourselves and walk in someone else’s shoes, and optimal implementation of the newly advanced technology. Innovation shows its results through continuously hard working efforts known as "10 Thousand Hours Rule". As world uncertainty creates complexity we, instead of predicting, should therefore anticipate the future by creating and managing real options on contingent projects or elements of alternative optimal strategies. This should reflect into our portfolio strategy. Abstract in Bahasa Indonesia: Inovasi merupakan darah bagi suatu institusi untuk bisa hidup berkelanjutan serta menguntungkan. Inovasi berupa penemuan baru secara sistematis yang berawal dari empati, kemampuan untuk melihat dunia melalui mata orang lain, dan pemanfaatan secara optimal kemajuan teknologi yang ada. Inovasi baru menghasilkan buahnya melalui kerja keras, yaitu dengan mengikuti “Aturan 10 Ribu Jam” secara berkesinambungan. Ketidakpastian, interaksi, keterbatasan dan degradasi menciptakan kompleksitas tentang kebutuhan dan solusi di masa depan. Oleh sebab itu daripada meramalkan risiko yang bakal terjadi, kita sebaiknya memasang strategi berupa skenario untuk mereduksi akibat dari risiko masa depan yang tidak kita mengerti. Skenario ini dapat diperoleh lewat penciptaan dan penanganan beberapa pilihan nyata atas semua proyek antisipatif yang ada. Kata kunci: Inovasi, ketidakpastian dan kompleksitas, aturan 10 ribu jam, paradoks strategi, peta jalan, empati, kerja berkesinambungan.

    This article investigates the possible correlation between mechanical properties of fish feed pellets and their mechanical durability. Mechanical properties were obtained by texture profile analysis (TPA) and stress relaxation test (SRT) of different types of fish feed. The results were correlated...... against a conventional test of mechanical durability (DORIS, Durability On a Realistic, test). From SRT it was found that for achieving a high durability, pellets should be able to relax an applied force nonelastically. From TPA, it was found that a durable pellet should also be able to return its...

The interplay between durability and sectoral production linkages fundamentally alters the intersectoral stabilization trade....... Aggregating durable and non-durable inflation depending on the relative degrees of sectoral price stickiness may induce a severe bias.

    Full Text Available Sprays are among the very main factors of mixture formation and combustion quality in almost every (IC engine. They are of great importance in pollutant formation and energy efficiency although adequate modeling is still on development. For many applications, validation and calibration of models are still an open question. Therefore, we present an overview of existing models and propose some trends of improvement. Models are classified in zero dimensional and dimensional classes ranging from simple formulations aimed at close-to-real-time applications to complete detailed description of early atomization stages. Les sprays sont parmi les principaux facteurs de qualite, dans la formation du melange et la combustion, dans un grand nombre de moteurs (a combustion interne. Ils sont de toute premiere importance dans la formation de polluants et l’efficacite energetique, bien qu’une modelisation adequate soit encore en developpement. Pour un grand nombre d’applications, la validation et la calibration de ces modeles demeurent une question ouverte. Aussi, presentons-nous un apercu des modeles existants et proposons quelques voies d’amelioration.

    Full Text Available L’implantation de nouvelles lignes de tramway peut-elle contribuer à l’émergence d’une ville durable ? Pour répondre à cette question, cet article part d’un modèle théorique insérant le système économique de transport dans trois environnements : environnement économique général, environnement social, environnement naturel. Une nouvelle ligne de tramway correspond à une nouvelle offre dans le système économique de transport d’une aire urbaine. Cette nouvelle offre produit des effets potentiels sur le système économique de transport et sur ses trois environnements. Ces effets sont recensés à partir de différentes études des agences d’urbanisme de Nantes, Grenoble et Strasbourg. Ils sont regroupés dans trois espaces géométriques : la ligne, le corridor, le périmètre. Il est possible ensuite d’organiser ces espaces en territoires concrets correspondant à la rue, aux quartiers accessibles à pied et à l’ensemble de la ville. Le projet de ville durable a alors pour ambition d’utiliser les effets potentiels du tramway moderne pour une reproduction conjointe dans l’espace urbain de la sphère économique, de la sphère sociale et de la biosphère.How can new tramways lines promote the development of sustainable cities? This article attempts to address this question through the use of a theoretical model, which situates the economic transport system within three contexts: the larger economic environment, the social environment and the natural environment. A new tramway line constitutes a new supply within the economic transport system of an urban area and this supply in turn produces potential effects within that system and its three environments. These effects, which are identified on the basis of studies carried out by urban planning agencies in Nantes, Grenoble and Strasbourg, are grouped together in three geometrical configurations: the line, the corridor, and the perimeter. These forms can then be

    2012-02-01

    In the summer of 2007, the U.S. Department of Energy (DOE) initiated a test program to evaluate the potential impacts of intermediate ethanol blends (also known as mid-level blends) on legacy vehicles and other engines. The purpose of the test program was to develop information important to assessing the viability of using intermediate blends as a contributor to meeting national goals for the use of renewable fuels. Through a wide range of experimental activities, DOE is evaluating the effects of E15 and E20 - gasoline blended with 15% and 20% ethanol - on tailpipe and evaporative emissions, catalyst and engine durability, vehicle driveability, engine operability, and vehicle and engine materials. This report provides the results of the catalyst durability study, a substantial part of the overall test program. Results from additional projects will be reported separately. The principal purpose of the catalyst durability study was to investigate the effects of adding up to 20% ethanol to gasoline on the durability of catalysts and other aspects of the emissions control systems of vehicles. Section 1 provides further information about the purpose and context of the study. Section 2 describes the experimental approach for the test program, including vehicle selection, aging and emissions test cycle, fuel selection, and data handling and analysis. Section 3 summarizes the effects of the ethanol blends on emissions and fuel economy of the test vehicles. Section 4 summarizes notable unscheduled maintenance and testing issues experienced during the program. The appendixes provide additional detail about the statistical models used in the analysis, detailed statistical analyses, and detailed vehicle specifications.

Walaupun assumsi yang berkembang itu dapat dimaklumi, namun keyakinan tersebut tentu saja tidak sepenuhnya benar. Karena meskipun terdapat sekelompok orang Islam yang berbuat radikal, akan tetapi mayoritas Muslim justru bertentangan dengan mereka. Lagi pula, jika dicermati secara mendalam, sesungguhnya Islam sama sekali tidak mentolerir tindakan radikal. Ia adalah agama kasih sayang yang sangat mendodrong penganutnya untuk berbuat baik terhadap orang lain, termasuk kepada orang-orang non-Muslim.

    Full Text Available Cette édition de la Revue internationale de politique de développement analyse les bouleversements qui affectent l’aide au développement, notamment eu égard aux politiques publiques globales et aux pays émergents. Dans cet article introductif, les auteurs examinent les mutations du contexte et de la géographie de la pauvreté dans le monde pour aborder le rôle des agences d’aide dans les pays à revenu intermédiaire (PRI. Ils examinent deux motifs qui plaident pour la poursuite de l’engagement des donateurs dans ces pays. Premièrement, il est dans l’intérêt des pays à faible revenu de voir les donateurs traditionnels et les PRI collaborer à la conception et la mise en œuvre de politiques globales pour protéger les biens publics mondiaux. Deuxièmement, les agences de coopération peuvent contribuer à réduire la pauvreté dans les PRI, nonobstant la nature hautement politique et délicate d’un tel engagement parallèle à l’émergence des classes moyennes et des organisations de la société civile dans les PRI. En conclusion, la cohérence des politiques publiques en faveur du développement durable peut servir de référence commune aux pays industrialisés comme aux PRI pour faire avancer l’agenda de la lutte contre la pauvreté avec celui de la préservation des biens publics mondiaux.

    Traumatic fear memories are highly durable but also dynamic, undergoing repeated reactivation and rehearsal over time. While overly persistent fear memories underlie anxiety disorders such as posttraumatic stress disorder, the key neural and molecular mechanisms underlying fear memory durability remain unclear. Post-synaptic density 95 (PSD-95) is a synaptic protein regulating glutamate receptor anchoring, synaptic stability and certain types of memory. Employing a loss-of-function mutant mouse lacking the guanylate kinase domain of PSD-95 (PSD-95GK), we analyzed the contribution of PSD-95 to fear memory formation and retrieval, and sought to identify the neural basis of PSD-95-mediated memory maintenance using ex vivo immediate-early gene mapping, in vivo neuronal recordings and viral-mediated knockdown approaches. We show that PSD-95 is dispensable for the formation and expression of recent fear memories, but essential for the formation of precise and flexible fear memories and for the maintenance of memories at remote time points. The failure of PSD-95GK mice to retrieve remote cued fear memories was associated with hypoactivation of the infralimbic cortex (IL) (not anterior cingulate (ACC) or prelimbic cortex), reduced IL single-unit firing and bursting, and attenuated IL gamma and theta oscillations. Adeno-associated PSD-95 virus-mediated knockdown in the IL, not ACC, was sufficient to impair recent fear extinction and remote fear memory, and remodel IL dendritic spines. Collectively, these data identify PSD-95 in the IL as a critical mechanism supporting the durability of fear memories over time. These preclinical findings have implications for developing novel approaches to treating trauma-based anxiety disorders that target the weakening of overly persistent fear memories. PMID:25510511

    The traveler participated in the fourth meeting of RILEM 100-TSL, Techniques for Service Life Prediction,'' and The Fifth International Conference on Durability of Building Materials and Components.'' In addition, the traveler met with staff members at Taywood Engineering Ltd., Electricite de France, and AEA Technology. The meeting pertained to performance of concrete materials in nuclear power plant structures, time variation of concrete material properties, methods for evaluating concrete structures, and modeling to predict the effects of degradation factors on concrete materials. As many of the concrete structures in general civil engineering applications as well as nuclear power plant applications in Europe are aging, there is increasing emphasis on assessing the durability of these structures. Information was provided of direct application to the Structural Aging Program which would not have been available without these visits. Of equal, or possibly more importance, was the individual contacts established at the organizations visited. Each organization was extremely interested in both the approach and scope of the Structural Aging Program and requested that they be informed of progress. The initial steps were taken to cooperate with several of these researchers and this should help the Structural Aging Program keep abreast of related European activities. In summary, information obtained during this trip will benefit the ongoing Structural Aging Program by informing Oak Ridge National Laboratory (ORNL) of the extensive European research programs addressing the durability of concrete structures, and also by forming and strengthening acquaintances with counterparts in other countries, thus enhancing the basis for possible international cooperation.

    The Solar Heating and Lighting Program has set the goal of reducing the cost of solar water heating systems by at least 50%. An attractive approach to such large cost reduction is to replace glass and metal parts with less-expensive, lighter-weight, more-integrated polymeric components. The key challenge with polymers is to maintain performance and assure requisite durability for extended lifetimes. We have begun evaluation of several new UV-screened polycarbonate sheet glazing constructions. This has involved interactions with several major polymer industry companies to obtain improved candidate samples. Proposed absorber materials were tested for UV resistance, and appear adequate for unglazed ICS absorbers.

Peel strength test, dynamical mechanical thermal analysis (DMTA), infrared spectroscopy (IR) and energy dispersive X-ray spectroscopy (EDX) were employed for measurements. Peel strength indicated the development of adhesive property of the coating, DMTA indicated the development of physical property, IR revealed the development of chemical structure, and EDX showed surface element change of the coating. All these results show a good time-temperature equivalence characteristic between humidity aging time and temperature.

    - We are considering a toroidal plasma centred around a closed {gamma}. When the rotational transform L/2{pi} approach an integer k if some specific relations are not satisfied curvature effects can become very important. When the rotational transform is created by current flowing in the plasma this happen if the coefficient a{sub k} of the Fourier expansion of curvature 1/R(s) of is non equal zero. One find then that the influence of a{sub k} is preponderant and that is possible to neglect all the other members of the series to study the neighbourhood of the corresponding equilibrium singularity. By developing an adapted coordinate system it is thus possible to take into account curvature effects at the lowest order. Equilibrium study bring us to introduce an equilibrium parameter {nu} {<=} 1 characterizing curvature effects. It is shown that the more {nu} is near of 1 the more shear and V{sup {phi}} quantities occurring in the stability criterion are important. Finally stability investigation show that the larger is the integer k the smaller is the domain of stability when L/2{pi} is near of k. (author) [French] Nous considerons un plasma toroidal centre autour d'une courbe fermee {gamma}. Lorsque la transformation rotationnelle L/2{pi} est voisine d'un nombre entier k, si certaines relations ne sont pas satisfaites, les effets de courbure peuvent devenir tres importants. Quand la transformation rotationnelle est cree par les courants circulant dans le plasma ceci se produit si le coefficient a{sub k} du developpement en serie de Fourier de la courbure 1/R(s) de {gamma} est non nul.

En developpant un systeme de coordonnees adapte il est alors possible de tenir compte des le premier ordre des effets de courbure. L' etude de l'equilibre conduit a

  1. Durability of composites in a marine environment

    CERN Document Server

    Rajapakse, Yapa

    2014-01-01

    Composites are widely used in marine applications. There is considerable experience of glass reinforced resins in boats and ships but these are usually not highly loaded. However, for new areas such as offshore and ocean energy there is a need for highly loaded structures to survive harsh conditions for 20 years or more. High performance composites are therefore being proposed. This book provides an overview of the state of the art in predicting the long term durability of composite marine structures. The following points are covered: •       Modelling water diffusion •       Damage induced by water •       Accelerated testing •       Including durability in design •       In-service experience. This is essential reading for all those involved with composites in the marine industry, from initial design and calculation through to manufacture and service exploitation. It also provides information unavailable elsewhere on the mechanisms involved in degradation and how to t...

  2. Durable Nanocomposites for Superhydrophobicity and Superoleophobicity

    Science.gov (United States)

    Steele, Adam

    Anti-wetting surfaces and materials have the potential for dramatic performance improvements such as drag reduction on marine vehicles and fluid power systems as well as anti-fouling on aircraft and wind turbines. Although a wide variety of synthetic superhydrophobic surfaces have been developed and investigated, several critical obstacles remain before industrial application can be realized, including: (1) large surface area application, (2) multi-liquid anti-wetting, (3) environmentally friendly compositions, (4) mechanical durability and adhesion, and (5) long-term performance. In this dissertation, nanocomposite coatings have been investigated to generate high performance anti-wetting surfaces that address these obstacles which may enable application on wind turbine blades. Solution processable materials were used which self-assemble to create anti-wetting nanocomposite surfaces upon spray coating and curing. As a result, the first superoleophobic nanocomposite, the first environmentally friendly superhydrophobic compositions, and the first highly durable superhydrophobic nanocomposite coatings were created. Furthermore, the mechanisms leading to this improved performance were studied.

    2007-12-15

    This thesis is related to the research and development program for the production of radioactive ion beams by the ISOL method for SPIRAL at GANIL. Two studies concerning improvements to the performance of SPIRAL target-source system have been made, using a statistical approach to the atoms-to-ions transformation. The first study concerns the transformation time between the production of the radioactive atoms of Ar{sup 35} inside a target and the extraction of the radioactive ions from the source with the TARGISOL set-up (target + ECR source). The goal was to determine the diffusion coefficients of the Ar for the carbon target. The results that are presented illustrate the difficulty of this work. The second study is the application of the statistical approach to the surface ionization source. It allowed one to define and to build a new MonoNaKe set-up for the production of 1{sup +} radioactive alkaline ions. Radioactive ions of K{sup 37,47}, Na{sup 25,26,27,28,30}, Li{sup 8,9} and Al{sup 28,29,30,31} were produced. For the production of the multicharged radioactive alkali ions, the MonoNaKe target/ion-source system was coupled to the ECR source of SPIRAL-1 without a mass separator (1{sup +}/N{sup +} direct method). A first radioactive ion beam of {sup 47}K{sup 5+} was extracted at the SIRa test bench. A surface ionization test source based on the same technical characteristics of MonoNaKe has been built. The goal of this system will be to define a prototype of source adapted to the constraints of SPIRAL-2 (ionization efficiency and lifetime). (author)

  9. Influence des melanges complexes organiques sur le sort des dioxines et furanes: Implications dans le developpement de facteurs de caracterisation en analyse du cycle de vie

    Science.gov (United States)

    Taing, Eric

    The environmental fate of dioxins and furans, or polychlorodibenzo-p-dioxins and -furans (PCDD/Fs), leaching from wood poles treated with pentachlorophenol (PCP) oil is modified by the presence of oil. Interactions between co-contaminants, which also exist for other pollutants within the mixtures, were shown in the specific context of risk analysis, but have never been taken into account for the generic context of life cycle assessment (LCA). This decision-making tool relies on characterization factors (CF) to estimate the potential impacts of an emitted amount of a pollutant in different impact categories such as aquatic ecotoxicity and human toxicity. For these two impact categories, CFs are calculated from a cause-effect chain that models the environmental fate, exposure and effects of the pollutant (represented by a matrix of fate FF, exposure XF and effect EF, respectively), meaning that a modification of PCDD/Fs fate induces a change in PCDD/Fs CFs. The research question is therefore as follows: In life cycle impact assessment (LCIA), to what extent would the potential impacts of PCDD/Fs on aquatic ecotoxicity and human toxicity change when taking into account the influence of a complex organic mixture on PCDD/Fs fate?. Thus, the main objective is to develop CFs of PCDD/Fs when their fate is influenced by PCP oil and compare them with the CFs of PCDD/Fs without oil for the aquatic ecotoxicity and human toxicity impact categories. A mathematic approach is established to determine the new environmental distribution of PCDD/Fs in the presence of oil and a new FF' matrix is calculated from this new distribution to obtain new CFs' integrating oil influence. FF' and CF' are then compared to FF and CF of PCDD/Fs without the oil. Finally, potential (eco)toxic impacts of the PCDD/F Canadian emissions are calculated with the new CFs' of PCDD/Fs in presence of oil. By only focusing on the results for an emission into air, freshwater and natural soil on a continental scale, the overall elimination fractions of 2,3,7,8-TCDD changed significantly. For the three emissions, organic fractions increased the overall elimination fraction of 2,3,7,8-TCDD into the continental air compartment, induced by a higher volatility of organic fractions than 2,3,7,8-TCDD: for an emission into continental air, organic fractions increased the overall elimination fraction of 2,3,7,8-TCDD in the continental air from 29% to 49% at most. For an emission into continental freshwater, 2,3,7,8-TCDD fate was mainly influenced by two groups of organic fractions: the lightest ones that volatilize into continental air (overall elimination fraction of 2,3,7,8-TCDD increasing from 2% to 35%) and the heaviest ones that are removed by sedimentation (DTCDD,fwC,fwC from 87% up to 96%). Therefore, an approach has been proposed to represent the carrier behaviour of the oil for PCDD/Fs. PCDD/F potential impacts in aquatic ecotoxicity and human toxicity change in a range up to two orders of magnitude depending on the emitting compartment (except for the seawater and ocean compartments). As 2,3,7,8-TCDD is one of the most toxic pollutant, this changing is significant in LCA. To assess the validity of the model's result, it is recommended to carry out laboratory experiments on the PCDD/F volatilization with oil. In addition, it could be interesting to integrate the influence of PCP on PCDD/Fs fate and, more broadly, the influence of all cocontaminants on PCDD/Fs exposure and effects. Moreover having a unique CFeco and CF tox via a weighting of the 17 CF'eco and the 17 CF' tox, respectively, is necessary for a use in LCA. Unfortunately the variability of the composition makes the weighting difficult, so it is suggested to calculate the mean CF'eco and CF'tox. Finally this research could be carried out on other pollutants whose fate is known to be modified by a complex organic mixture in an effort to ensure that impact characterization better reflects reality.

    Within the group of malformations of cortical development, focal cortical dysplasia (FCD) are an increasingly recognized cause of intractable epilepsy that can be cured by surgery. The success of cortical resection for intractable epilepsy is highly dependent on the accurate pre-surgical delineation of the regions responsible for generating seizures. [{sup 18}F]-FDG PET, which images cerebral metabolism studying brain glucose uptake, is the most established functional imaging modality in the evaluation of patients with epilepsy. The aim of this article is to review [{sup 18}F]-FDG PET usefulness as a pre-surgical tool in the evaluation of medically refractory partial epilepsy. It has an established place in assisting in the localisation and definition of FCD in patients with no lesion, or only a subtle abnormality, on MRI. The role of FDG-PET in defining the extent of the surgical resection is still uncertain and needs to be the focus of future research. (authors)

    Although gene therapy has been proposed first for genetic diseases, its concept has been extended to many acquired diseases, owing to a better understanding of pathology at a molecular level. Overall, very few trials have shown to be efficient, and safety concerns have emerged, as a result of several patients deaths. There is a need for new techniques able to improve both the knowledge of the therapeutic gene fate once administered and the early detection of events likely to lead to serious adverse events. In vivo imaging of a reporter gene associated with the therapeutic one is certainly the most promising technique for these goals. Among available imaging modalities, nuclear imaging is the most likely to be applied to patients. This review begins with a summary of current knowledge about the steps that a therapeutic gene has to cross from vector delivery to appropriate expression in target cells. We show how gene imaging could allow to investigate many pitfalls of trials by providing a better understanding of these steps in patients. The reporter genes available for nuclear imaging are presented in the second section, through animal studies. Then, relevant examples of clinical trials are presented. These include cancer (suicide gene therapy and adoptive immunotherapy), ischemic heart diseases and cystic fibrosis. The results are commented with emphasis on the role of nuclear imaging to address the questions raised by these studies, and imaging studies carried out on animals or patients for the corresponding diseases or organs are presented. The results obtained in animal studies warrant the introduction of gene imaging in clinical trials. (authors)

  16. Eco-efficience et analyse des couts du cycle de vie: Developpement d'un outil d'aide a la conception dans l'industrie aeronautique

    Science.gov (United States)

    Mami, Fares

    The aeronautical sector, responsible for about 3 % of the world emissions of greenhouse gases, predict a 70 % growth in 2025 and 300 % to 500 % in 2050 of its emissions compared to the level of 2005. The decision-makers must thus be supported in their choice of conception to integrate the environmental aspect into the decision-making. Our industrial partner in the aeronautical sector developed an expertise in Life Cycle Assessment (LCA) and seeks to integrate the costs and the environmental impacts in a systematic way into the ecodesign of products. Based on the literature review and the objectives of this research we propose a model of eco-efficiency, which integrates LCA with Life Cycle Costing (LCC). This model is consistent with defined cost cutting and environmental impacts reduction targets and allows a simple interpretation of the results while minimizing the efforts during data collection. The model is applied for 3D printing as an alternative production process in the manufacturing of an aircraft blocker door. 3D printing is a new technology of production working by addition of material and present interesting opportunities of cost cutting and environmental impacts, particularly in the aeronautical domain. The results showed that 3D printing, when associated with improvement in the topology of the part, allows an improvement both on costs and environmental impacts of the part life cycle. Nevertheless, the results are sensitive to the productivity of the 3D printing machine, in particular with costs when the productivity of the 3D printing is reduced. This eco-efficiency model presents several opportunities of improvement. A more elaborate definition of the objectives in reduction of environmental impacts would allow to direct the choices in design to considerations of eco-efficiency at a macro level. Moreover, the integration of the social dimension in the model constitutes an important stage to operationalize the stakes of environmental and social responsibility of the company.

    Pochet, Steven

    The measurement of the void fraction is an important parameter in many industrial fields. Whether it is to prevent the phenomenon of critical heat flux in heat tube of thermal power plants, the explosion of gas pockets in oil rigs’ pipes or to detect bubbles in medical catheters, the knowledge of the void fraction can be a key parameter in many diverse applications. Several invasive and non-invasive measurements techniques have been developed these last decades and are based on the difference between the physical properties of liquid and gas. Some of these techniques are not always possible to implement due to restrictions in the geometry of tubes or regulatory standards limiting their use. Throughout this work we propose a new non-invasive void fraction measurement technique based on the reflection of electromagnetic waves on the water-air interface of the mixture. The reflection of electromagnetic wave is induced by a change in the impedance of the propagation medium. The impedance is function of the dielectric properties of the medium. The characteristics of air and water being distinct, it is possible to calculate the complex reflection coefficient at the interface of a double phase mixture. To this end, mathematical modeling of the response of an electromagnetic wave in a tube containing a two phase mixture was made using the model of transmission lines, applicable to microwave frequencies we use. The effects of the amount of air in water and the position of the bubbles in the section of the tube were simulated. It was shown that the phase of the reflected wave was sensitive to the position of bubbles in the tube’s section and that the magnitude of the reflection coefficient varied with the mixture’s void fraction. Subsequently, we designed and built a six-ports reflectometer operating at 2.45 GHz. This system allows the processing and calculation of the reflected wave from the incident wave. A six-ports network, a patch antenna, a wave generator and an amplifier were simulated using HFSS and ADS software. They were then built using the technology of micro-strips on dielectric laminates and the entire system was then calibrated at 6 different frequencies near 2.45 GHz. To this end, we used 4 and 5 loads calibration algorithms that gave us calibrated results with less than 2 % errors. Afterwards, the system was implemented: the antenna was placed tangent to the wall of a vertical tube and connected to the six-ports which was connected to a computer recording and displaying the results in real time. A valve positioned under the tube allows air into the tube and to vary the flow rate. The results showed that the system was sensitive to changes in void fraction from 1% and followed the predictions of the simulated model to a void fraction of about 10%. Possibly du to a change in the structure of the flow for a void fraction of 10%, the signal no longer varies monotonically with respect to the increasing void fraction possibly because of a change in the flow’s configuration. It was shown that the Rayleigh scattering phenomena of air bubbles was involved in the reflection coefficient response. Pictures of the stream at various void fraction state were taken and confirmed a change in the flow’s configuration. By placing a Plexiglas rod to simulate a flow geometry located in the section of the tube, it was noted that the change in phase of the reflected wave was the same as the model when the rod was placed in an empty tube (very few attenuation loss environment). Hence, it is possible to determine the distance of an object in a section of tube from the measurement of the reflected wave’s phase. When the rod is in a very absorbent medium such as water, it is possible to detect a moving rod when it is sufficiently close to the antenna (less than two wavelengths) thanks again to the phase variation. However, detection is still much more difficult due to the absorption of water and can not function effectively for tubes with high diameters compared with the electromagnetic wavelength used.

    Radioactive waste constitute a major issue for the nuclear industry. One of the key points is their characterization to optimize their management: treatment and packaging, orientation towards the suited disposal. This thesis proposes an evaluation method of the low-energy photon attenuation, based on the gamma-ray spectra Compton continuum. Effectively, the {sup 241}Am measurement by gamma-ray spectrometry is difficult due to the low energy of its main gamma-ray (59.5 keV). The photon attenuation strongly depends on the bituminous mix composition, which includes very absorbing elements. As the Compton continuum also depends on this absorption, it is possible to link the 59.5 keV line attenuation to the Compton level. Another technique is proposed to characterize uranium thanks to its fluorescence X-rays induced by the gamma emitters already present in the waste. The uranium present in the drums disturbs the neutron measurements and its measurement by self-induced X-ray fluorescence allows to correct this interference. Due to various causes of error, the total uncertainty is around 50 % on the activity of the radioisotope {sup 241}Am, corrected by the peak to Compton technique. The same uncertainty is announced on the uranium mass measured by self induced X-ray fluorescence. As a consequence of these promising results, the two methods were included in the industrial project of the 'Marcoule Sorting Unit'. One major advantage is that they do not imply any additional material because they use information already present in the gamma-ray spectra. (author)

    We present a short review of current theories of glass weathering, including glass dissolution, and hydrolysis of nuclear waste glasses, and leaching of historical glasses from an XAFS perspective. The results of various laboratory leaching experiments at different timescales (30 days to 12 years) are compared with results for historical glasses that were weathered by atmospheric gases and soil waters over 500 to 3000 years. Good agreement is found between laboratory experiments and slowly leached historical glasses, with a strong enrichment of metals at the water/gel interface. Depending on the nature of the transition elements originally dissolved in the melt, increasing elemental distributions are expected to increase with time for a given glass durability context.

    This is essentially a review paper, bringing together the various studies undertaken at the University of Dundee as well as many others selected from published work. A full range of durability properties have been considered dealing with the effects of fly ash (FA) in concrete. It is shown that the use of FA generally effects improvement in the resistance of concrete to various forms of attack. FA is shown to greatly improve concrete resistance to chloride ingress and to reduce expansion caused by ASR. In the case of sulphate attack the use of FA is recommended. With regard to carbonation, FA can slightly reduce the resistance. It is also shown that FA concrete will benefit more from curing than OPC concrete in developing its resistance to deterioration with age. 78 refs., 8 figs., 5 tabs.

  7. Advancing a comprehensive understanding of concrete durability

    Moss, Gates Minckler

    The durability of concrete is vital to the health of our infrastructure and economy. Unfortunately, traditional, linear approaches to experimentation and specification have not provided a complete understanding and control of this complex material. This work seeks to further a comprehensive understanding of concrete durability through approaches including multi-variable mathematical modeling of premature deterioration, analysis of the microstructural changes of cement paste and mortar during freezing, and the development of quantitative computer models in parallel with actual experiments. The first section includes a summary of the collection and analysis of data describing concrete pavements in a number of Midwestern states. This involves the development of a thorough survey, completion of that survey by local organizations, and the creation of a database from pooled data. Statistical analysis of that data reveals a number of statistically significant trends in a pavement's tendency to deteriorate. Statistically important variables include total alkali and sulfate content of the cementitious material, the presence of type C fly ash, ambient paving temperature, age, and permeability of the base course material. In the second section, deformation mapping of cement paste during freezing illustrates the power and accuracy of this new technique. It also illustrates the effects of water/cement ratio, age, presence of aggregate, and repeated cycling on deformation during freezing. Finally, the increased resolution of this new technique allows for the identification of a number of new microstructural features of the freezing process. Computer modeling closely mirrors the deformation analysis described above. Effects of water/cement ratio, age, and the presence of aggregate are all predicted by the models. Also, the trends and magnitude of bulk deformation predicted are very similar to measured results. Any differences can be attributed to the elastic nature of the models

  8. Some durability aspects of hybrid alkaline cements

    2014-04-01

    Full Text Available Blended cements that contain a high content of fly ash and a low content of Portland cement typically suffer from low early strength development and long setting times. Recently, one method of overcoming these problems has been to use an alkali activator to enhance the reactivity of fly ash particles at early ages. Such cements can be grouped under the generic term “hybrid alkaline cements”, where both cement clinker and fly ash, encouraged by the presence of alkalis, are expected to contribute to cementitious gel formation. The work presented here examines some of the durability aspects of high fly ash content hybrid alkaline cement. Specifically, the aspects investigated were: exposure at high temperatures (up to 1000°C, resistance to immersion in aggressive solutions and susceptibility to the alkali aggregate reaction. All tests were repeated with a commercially available sulfate resistant Portland cement for comparison. When exposed to high temperatures, the hybrid alkaline cement showed strikingly different behaviour compared to the control Portland cement, showing fewer micro-cracks and maintaining residual compressive strengths at least equal to original strengths. Beyond 700°C, the hybrid alkaline cement began to sinter, which resulted in shrinkage of around 5% and a 100% increase in residual compressive strengths. No such sintering event was noted in the control Portland cement, which showed a drastic loss in residual compressive strengths upon heating. In immersion tests, the hybrid alkaline cement possessed excellent resistance to sulfate and seawater attack, similar to the control sulfate resistant cement. Both cements were however severely degraded by immersion in 0.1M HCl for 90 days. Both binders complied with the accelerated alkali-aggregate test but when this test was extended, the hybrid alkaline binder showed much greater dimensional stability. Possible reasons for the differences in durability behaviour in both cements

    Interaksi antar etnis, agama dan budaya bukanlah barang langka di Bali. Sejak semula hal tersebut sudah ada, ketika pulau ini menjadi locus perdagangan hasil bumi. Sebab sesungguhnya kebudayaan Bali menjujung tinggi nilai-nilai keseimbangan dan harmonisasi antar manusia dengan Tuhan (perhyangan, dengan sesama (pawongan dan dengan lingkungan (palemahan. Konsep ini disebut Tri hita karana. Bali kini berubah. Budayanya berorientasi pada jasa, yang berkait dengan industri pariwisata. Sikap orang Bali kini tidak lagi ramah dan harmoni. Akibat ledakan bom dalam bulan Oktober 2002 dan 2005, masyarakat lebih berhati-hati terhadap para pendatang. Ajeg Bali merupakan kearifan lokal –agama dan budaya– masyarakat Bali dalam rangka menanggulangi pengaruh luar yang mengakibatkan perubahan di berbagai bidang sehingga identitas kebalian mengalami degradasi. Ajeg Bali merupakan bentuk resistensi masyar­akat Bali dalam rangka membatasi pendatang dari luar Bali. Kajian ini berusaha untuk menjawab pertanyaan “apakah Ajeg Bali, sebuah kearifan lokal masyarakat Bali dapat membendung pengaruh budaya, agama dan ekonomi masyarakat Bali?”

  17. Developpement des betons semi autoplacants a rheologie adaptee pour des infrastructures

    Science.gov (United States)

    Sotomayor Cruz, Cristian Daniel

    Au cours des dernières décennies, les infrastructures canadiennes et québécoises comportent plusieurs structures en béton armé présentant des problèmes de durabilité dus aux conditions climatiques sévères, à la mauvaise conception des structures, à la qualité des matériaux, aux types des bétons choisis, aux systèmes de construction ou à l'existence d'événements incontrôlables. En ce qui concerne le choix du béton pour la construction des infrastructures, une vaste gamme de béton divisée en deux principaux types peut être utilisée: le béton conventionnel vibré (BCV) et le béton autoplaçant (BAP). Dans le cas d'un BCV, la consolidation inadéquate par vibration a été un problème récurrent, occasionnant des dommages structuraux. Ceci a conduit à une réduction de la durabilité et à une augmentation du coût d'entretien et de réparation des infrastructures. Rien que l'utilisation d'un BAP a des avantages tels que l'élimination de la vibration, la réduction des coûts de main d'oeuvre et l'amélioration de la qualité des structures, néanmoins, le coût initial d'un BAP par rapport à un BCV ne permet pas encore de généraliser son utilisation dans l'industrie de la construction. Ce mémoire présente la conception d'une nouvelle gamme de béton semi-autoplaçant pour la construction des infrastructures (BSAP-I) exigeant une vibration minimale. Il s'agit de trouver un équilibre optimal entre la rhéologie et le coût initial du nouveau béton pour conférer une bonne performance structurale et économique aux structures. Le programme expérimental établi a premièrement permis d'évaluer la faisabilité d'utilisation des BSAP-I pour la mise en place des piliers d'une infrastructure de pont à Sherbrooke. En plus, l'utilisation d'un plan d'expériences a permis l'évaluation de trois paramètres de formulation sur les propriétés des mélanges de BSAP-I à l'état frais et durci. Finalement, l'évaluation de la performance des

    Full Text Available Considered one of the largest urban forests in the world and the third largest in Brazil, the Tijuca Forest, in the city of Rio de Janeiro, faces the great challenge of living harmoniously and sustainably with the 46 slums located around it. One of these communities, Vale Encantado, whose occupation dates from the mid-eighteenth century, experienced the various production cycles that developed in the area, through logging, farming, livestock production, ornamental plants and black granite mining. To a greater or lesser degree, these production cycles impacted negatively on the native forest. However, simultaneously with this process, the Vale Encantado community has witnessed the implementation of reconstruction and conservation efforts of this fragment of Atlantic Rainforest, through reforestation and the creation of the Tijuca National Park in 1961. Today, through sustainable tourism and the social cuisine program, Vale Encantado has become a benchmark in the process of coexistence, integration and conservation of the local environment, and is the acknowledged "guardian of the forest."Considérée comme une des plus grandes forêts urbaines du monde et la troisième plus grande du Brésil, la Forêt de Tijuca, située dans la Ville de Rio de Janeiro, est face à un grand défi : cohabiter de façon harmonieuse et durable avec les 46 favelas qui l’entourent. L’une de ces communautés, le Vale Encantado, dont la présence remonte au milieu du XVIIIe siècle, a connu les différents cycles de production qui y ont été développés : l’extraction de bois, l’exploitation agricole, l’élevage, la culture de plantes ornementales et l’extraction du granit noir. Ces cycles de production ont, directement ou indirectement, eu un effet négatif sur la forêt primaire.

    2017-03-29

    The past decade saw a drastic increase in the understanding and applications of superhydrophobic surfaces (SHSs). Water beads up and effortlessly rolls off a SHS due to its combination of low surface energy and texture. Whether being used for drag reduction, stain repellency, self-cleaning, fog harvesting, or heat transfer applications (to name a few), the durability of a SHS is critically important. Although a handful of purportedly durable SHSs have been reported, there are still no criteria available for systematically designing a durable SHS. In the first part of this work, we discuss two new design parameters that can be used to develop mechanically durable SHSs via the spray coating of different binders and fillers. These parameters aid in the rational selection of material components and allow one to predict the capillary resistance to wetting of any SHS from a simple topographical analysis. We show that not all combinations of sprayable components generate SHSs, and mechanically durable components do not necessarily generate mechanically durable SHSs. Moreover, even the most durable SHSs can eventually become damaged. In the second part, utilizing our new parameters, we design and fabricate physically and chemically self-healing SHSs. The most promising surface is fabricated from a fluorinated polyurethane elastomer (FPU) and the extremely hydrophobic small molecule 1H,1H,2H,2H-heptadecafluorodecyl polyhedral oligomeric silsesquioxane (F-POSS). A sprayed FPU/F-POSS surface can recover its superhydrophobicity even after being abraded, scratched, burned, plasma-cleaned, flattened, sonicated, and chemically attacked.

    Full Text Available The paper presents methods for determining the durability of slide bearings. The developed methods enhance the calculation process by even 100000 times, compared to the accurate solution obtained with the generalized cumulative model of wear. The paper determines the accuracy of results for estimating the durability of bearings depending on the size of blocks of constant conditions of contact interaction between the shaft with small out-of-roundedness and the bush with a circular contour. The paper gives an approximate dependence for determining accurate durability using either a more accurate or an additional method.

    Marois, Marc-Andre

    Ce projet de recherche porte sur une methode numerique permettant de predire l'evolution du profil 2D de la couche solide qui recouvre l'interieur des parois de plusieurs fours de transformation a haute temperature. Un modele mathematique base sur la formulation faible de l'energie est d'abord developpe et valide. Une methode de transfert thermique inverse reposant sur ce modele est ensuite developpee afin d'obtenir une mesure rapide et continue de l'evolution du profil de cette couche solide. Vu la grande inertie thermique du systeme a l'etude, differentes strategies sont proposees afin de faciliter la mise en uvre de cette methode numerique. Finalement, cette approche inverse est confrontee aux resultats experimentaux obtenus a l'aide d'un reacteur metallurgique. Une etude preliminaire montre que les fours de transformation presentent une tres grande inertie thermique qui limite grandement l'utilisation des methodes inverses. En effet, la sensibilite de cette methode numerique repose essentiellement sur le delai temporel observe entre la variation du profil du banc et la fluctuation de la temperature a la surface externe de la paroi du four. Les resultats obtenus demontrent qu'une partie de ce delai est proportionnel a la chaleur latente de fusion lorsque le materiau a changement de phase est constitue d'un melange non eutectique. Afin de limiter l'impact de ce delai temporel, deux astuces numeriques sont proposees : reutiliser plus d'une fois les mesures de temperature et modifier le probleme thermique dans les regions pateuse et liquide. D'une part, le concept de chevauchement propose permet de reduire le temps d'acquisition des donnees entre chacune des predictions. D'autre part, l'approche virtuelle developpee permet de reduire l'inertie thermique du systeme et, par le fait meme, le delai temporel associe a la diffusion de la chaleur. Ces deux strategies ont permis de predire efficacement l'evolution 1D de l'epaisseur de la couche de gelee qui se solidifie a

    The alkali activation of blast furnace slag has the potential to reduce the environmental impact of cementitious materials and to be applied in geographic zones where weather is a factor that negatively affects performance of materials based on Ordinary Portland Cement. The scientific literature provides many examples of alkali activated slag with high compressive strengths; however research into the durability and resistance to aggressive environments is still necessary for applications in harsh weather conditions. In this study two design mixes of blast furnace slag with mine tailings were activated with a potassium based solution. The design mixes were characterized by scanning electron microscopy, BET analysis and compressive strength testing. Freeze-thaw testing up to 100 freeze-thaw cycles was performed in 10% road salt solution. Our findings included compressive strength of up to 100 MPa after 28 days of curing and 120 MPa after freeze-thaw testing. The relationship between pore size, compressive strength, and compressive strength after freeze-thaw was explored.

    Full Text Available Tannin-boron wood preservatives were investigated for their resistance against outdoor agents. This work focused on the analysis of the causes that affect the durability of the tannin-hexamine-treated samples. In particular, dimensional stability, resistance to leaching, and resistance to biological agents were investigated. The combined effect of deterioration agents was evaluated by subjecting the treated samples to simulated and natural weathering tests. The study of the appearance and of the color components (L*, a*, and b* according to CIELAB space of the exposed samples was monitored to assess the efficacy of the tannin-boron formulations for outdoor applications. Significant resistance against the action of water (EN 84, ENV 1250-2 and insects (EN 47 has been demonstrated in specific tests. Conversely, the continuous stress due to artificial and natural weathering deteriorates the color and the visible features of the treated specimens. The combined effect of moisture modifications, solar exposition, and leaching cycles damages the structure of the tannin-based polymeric network and subsequently it negatively affects its preservation properties.

    Les evaporateurs de refrigeration sont surtout du type tube a ailettes, appeles serpentins, et fonctionnent dans l'une des conditions suivantes: seche, humide ou avec formation de givre. Il a ete demontre que la formation du givre sur la paroi exterieure de l'echangeur engendre une surconsommation energetique a cause des operations de degivrage puisque 15 a 20% seulement de la chaleur produite sert au degivrage tandis que le reste est dissipee dans l'environnement [1]. Avec l'avenement des nouveaux refrigerants, moins nocifs envers l'environnement, l'industrie du froid se trouve penalisee du fait que peu ou pas de composantes mecaniques (compresseur, pompe, echangeur...etc.) adaptees sont disponibles [3]. Il s'agit pour la communaute des frigoristes de combler ce retard technologique en redeveloppant ces composantes mecaniques afin qu'elles soient adaptees aux nouveaux refrigerants. Dans cette optique, et afin de mieux comprendre le comportement thermique des evaporateurs au CO2 fonctionnant dans des conditions seches, qu'un groupe de chercheurs du CanmetENERGIE avaient lance, en 2000, un programme de R & D. Dans le cadre de programme un outil de simulation des evaporateurs au CO2 a ete developpe et un banc d'essai contenant une boucle secondaire de refrigeration utilisant le CO2 comme refrigerant a ete construit.

Gangguan hemodinamik tersebut dapat berupa penurunan tahanan vaskuler sitemik terutama di arteri, berkurangnya darah balik, penurunan pengisian ventrikel dan sangat kecilnya curah jantung. Gangguan faktor-faktor tersebut disbabkan oleh bermacam-macam proses baik primer pada sistim kardiovaskuler, neurologis ataupun imunologis. Diantara berbagai penyebab syok tersebut, penurunan hebat volume plasma intravaskuler merupakan faktor penyebab utama. Terjadinya penurunan hebat volume intravaskuler dapat terjadi akibat perdarahan atau dehidrasi berat, sehingga menyebabkan yang balik ke jantung berkurang dan curah jantungpun menurun. Penurunan hebat curah jantung menyebabkan hantaran oksigen dan perfusi jaringan tidak optimal dan akhirnya menyebabkan syok. Pada tahap awal dengan perdarahan kurang dari 10%, gejala klinis dapat belum terlihat karena adanya mekanisme kompensasi sisitim kardiovaskuler dan saraf otonom.

    The durability of reinforced concrete structures represents a major concern to many investigators. The use of latex modified concrete (LMC) in construction has urged researchers to review and investigate its different properties. This study is part of a comprehensive investigation carried on the use of polymers in concrete. The main objective of this study to investigate and evaluate the main durability aspects of Styrene-Butadiene latex modified concrete (LMC) compared to those of conventional concrete. Also, the main microstructural characteristics of LMC were studied using a Scanning Electron Microscope (SEM). The SEM investigation of the LMC showed major differences in its microstructure compared to that of the conventional concrete. The LMC proved to be superior in its durability compared to the durability of conventional concrete especially its water tightness (measured by water penetration, absorption, and sorptivity tests), abrasion, corrosion, and sulphate resistance.

    The present study is undertaken to assess the durability of concrete blocks coated with red mud - fly ash based geopolymer paste. Concrete blocks of size 200 x 200 x 100mm were coated with geopolymer paste synthesized by varying the percentages of red mud and fly ash. Uncoated concrete blocks were also tested for the durability for comparison. In thermal resistance test, the blocks were subjected to 600°C for an hour whereas in acid resistance test, they were kept in 5% sulphuric acid solution for 4 weeks. The specimens were thereafter studied for surface degradation, strength loss and weight loss. Pastes with red mud percentage greater than 50% developed lot of shrinkage cracks. The blocks coated with 30% and 50% red mud paste showed better durability than the other blocks. The use of blocks coated with red mud - fly ash geopolymer paste improves the aesthetics, eliminates the use of plaster and improves the durability of the structure.

    Currency producers are facing dual marketplace demands to increase bank note circulation life and to employ increasingly effective security features against counterfeiting. Diffractive optically variable devices such as foil patches, stripes and windowed thread have become popular security features used for bank notes throughout the world, but historically have suffered in their ability to match the durability of the bank note substrate itself. A study to find a durable, diffractive OVD led to the development of a windowed-thread feature designed to pass stringent durability criteria for laundry, chemical soak and other performance tests. Diffractive-film production methods, demetallization techniques, thread construction and applied coatings were key factors in achieving this durability.

    Full Text Available Current commercial polymer membranes have shown high performance and durability in water treatment, converting poor quality waters to higher quality suitable for drinking, agriculture and recycling. However, to extend the treatment into more challenging water sources containing abrasive particles, micro and ultrafiltration membranes with enhanced physical durability are highly desirable. This review summarises the current limits of the existing polymeric membranes to treat harsh water sources, followed by the development of nanocomposite poly(vinylidene fluoride (PVDF membranes for improved physical durability. Various types of nanofillers including nanoparticles, carbon nanotubes (CNT and nanoclays were evaluated for their effect on flux, fouling resistance, mechanical strength and abrasion resistance on PVDF membranes. The mechanisms of abrasive wear and how the more durable materials provide resistance was also explored.

  8. Betons durables a base de cendres d'ecorces de riz

    Science.gov (United States)

    Wilson, William

    De nos jours, le développement durable est devenu une nécessité dans l'ensemble des sphères d'activité de notre monde, et particulièrement dans le domaine du béton. En effet, le développement des sociétés passe inévitablement par l'augmentation des infrastructures; le béton est le matériau principalement utilisé et son empreinte environnementale considérable gagnerait à être diminuée. L'industrie et la recherche sont très actives à ce niveau et la science des bétons durables est en pleine expansion. Dans ce contexte, une piste de solution est l'utilisation de résidus industriels ou agricoles comme ajouts cimentaires, ce qui permet de remplacer partiellement le ciment très polluant, tout en produisant des bétons avec une meilleure durabilité. Les cendres d'écorce de riz (RHA) présentent ainsi un potentiel cimentaire similaire aux meilleurs ajouts cimentaires actuellement utilisés, mais les applications concrètes de ce nouveau matériau demeurent peu développées à ce jour. Le présent projet a donc été conçu afin d'illustrer le potentiel des RHA d'une part dans les pays industrialisés pour améliorer la durabilité des bétons hautes performances (BHP) et pour améliorer les propriétés à l'état frais des bétons autoplaçants (BAP); et d'autre part, dans les pays en développement pour démocratiser les bétons durables produits avec des technologies adaptées aux réalités locales. Une première phase réalisée avec des RHA de haute qualité (RHAI) a ainsi été consacrée aux applications en pays industrialisés. La caractérisation des RHAI a indiqué une composition de 90% de silice amorphe, des particules légèrement plus grossières que le ciment, et une microstructure très poreuse et absorbante. Afin de pallier à cette absorption d'eau, l'optimisation du type de superplastifiant a permis de déterminer que l'utilisation du Plastol 5000 ou de l'Adva 405 avec les RHAI favorise un équilibre optimal entre dispersion

    Full Text Available Data Archiving and Networked Services (DANS, the Dutch scientific data archive for the social sciences and humanities, is engaged in the Migration to Intermediate XML for Electronic Data (MIXED project to develop open source software that implements the smart migration strategy concerning the long-term archiving of file formats. Smart migration concerns the conversion upon ingest of specific kinds of data formats, such as spreadsheets and databases, to an intermediate XML formatted file. It is assumed that the long-term curation of the XML files is much less problematic than the migration of binary source files and that the intermediate XML file can be converted in an efficient way to file formats that are common in the future. The features of the intermediate XML files are stored in the so-called Standard Data Formats for Preservation (SDFP specification. This XML schema can be considered an umbrella as it contains existing formal descriptions of file formats developed by others. SDFP also contain schemata developed by DANS, for example, a schema for file-oriented databases. It can be used, for example, for the binary DataPerfect format, that was used on a large scale about twenty years ago, and for which no existing XML schema could be found. The software developed in the MIXED project has been set up as a generic framework, together with a number of plug-ins. It can be considered as a repository of durable file format conversions. This paper contains an overview of the results of the MIXED project.

    Full Text Available This papers shows the evaluation process of the durability of compressed soil-cement bricks. A great number of tests were made to determine the behavior of bricks when they are compression loaded and under the influence of moisture. Two different types of soils were used to produce the bricks, a lime-clay soil and a sand one. The sand soil is very resistant. The other one has a limited use. An experimental design was used to test the bricks. It is a rotational and quadratic method with a hexagonal figure which contains replicas at the central point. This method ensures the reliability of test results. Otherwise, it would reduce the amount of specimens necessary for the tests. The optimun moisture content is obtained by using a press machine. It is more rational than the standard Proctor compactation test, because it applies the same type and amount of energy used to produce the bricks. The obtained results show the behavior differences between the two compressed soil-cement bricks subjected to the compression test, water absorption and wetting and drying tests. The durability tests results are very important in the possible use of the bricks produced.

Budaya politik dapat membentuk aspirasi, harapan, preferensi, dan prioritas tertentu dalam menghadapi tantangan yang ditimbulkan oleh perubahan sosial politik. Pada gilirannya, disimpulkan bahwa peran budaya politik santun, bersih dan beretika dalam rangka memperkokoh kehidupan berbangsa dan bernegara menuju Indonesia baru adalah: pertama, etika politik dan pemerintahan mengandung misi kepada setiap pejabat dan elite politik untuk bersikap jujur, amanah, sportif, siap melayani, berjiwa besar, memiliki keteladanan, rendah hati, dan siap untuk mundur dari jabatan publik apabila terbukti melakukan kesalahan dan secara moral kebijakannya bertentangan dengan hukum dan rasa keadilan masyarakat. Kedua, perlu dilakukan upaya penanaman suatu kesadaran bahwa politik yang hendak kita perjuangkan bukan semata politik kekuasaan, melainkan suatu politik yang mengedepankan panggilan pengabdian demi kesejahteraan masyarakat luas, dialektika antara partai dan politikus serta masyarakat yang kritis. Ketiga, budaya politik santun, bersih dan beretika ini diperlukan karena dapat membuat para elite politik menjauhi sikap dan perbuatan yang dapat merugikan bangsa Indonesia. Akhirnya, disarankan agar dilaksanakan kembali pendidikan budi pekerti yang merupakan pondasi bagi pelaksanaan Civic Education agar tercipta generasi yang tidak hanya mau menjadi politisi, namun paham budaya dan etika politik.   Kata kunci: budaya politik, kehidupan berbangsa dan bernegara, menuju Indonesia baru

Islam is the perfect religion that governs all things in life, including the economy. This is evident with the concept of  well-being which is described in the al-Quran and Sunnah. Basically the goal of every human life is to prosper, although humans make sense of  well- being with a different perspective. Most understand economics assume that welfare is the welfare of  earthly material. But to make sense of well-being with the term al-Falah, is meaning holistic wellbeing and balance between material and spiritual dimensions. al-Quran and Sunnah have taught that the human being will be achieved if  living in balance between material and spiritual. This is because human life does not just stop in the life of this world, but there is still a second life that will be faced by humanity in the hereafter, and well-being will be achieved with the truth is that people can balance the needs of the world and the hereafter, and that is what is taught in Islamic economics. Keywords: Islam, Economy, Prosperity. Tulisan ini bertujuan untuk menjelasakn tentang korelasi antara ekonomi  dan  Islam.  Islam  adalah  agama  yang  sempurna  yang mengatur segala hal dalam kehidupan ini, termasuk juga ekonomi.

    Since a long time, numerous precautions for welding have been integrated in the nuclear codes, in particular in the RCC-M applicable to pressurized water reactors, in order to guarantee a high quality level of permanent assemblies. In parallel, European and ISO standardization works have led to a harmonisation of practices on qualification of welding processes, welders and operators. In the context of the regulatory evolutions presented during this conference, it was judged appropriate to bring closer the RCC-M practices and those of EN and ISO standards, while taking the precaution of specifying, if necessary, the complementary provisions allowing maintaining guarantees of quality consistent with the prior experience feedback. This paper presents the amendments brought to the RCC-M Code by the 2005 and 2007 addenda, in order to respond to this objective, and develops their motivations.

Nous nous interrogeons dès lors sur le caractère résilient de ces déterminants sociaux dans la mesure où ils peuvent permettre la mise en place de projets et de stratégies effectives de développement durable. Enfin, notre réflexion prend appui sur quelques exemples concrets dans la Caraïbe mettant en relation le contexte social local et les actions de développement durable engagées. Selon les cas, ce socle social territorial peut être appréhendé comme un facteur de blocage ou un moteur de développement durable.Our article deals with sustainable development in the context of small islands developping states (SIDS.

Une étude croisée de deux villes de l’Ouest, Angers et Nantes, confrontées à une forte pression foncière dans un contexte de croissance démographique, nous montre que faire converger préoccupations patrimoniales et objectifs du développement durable ne va pourtant pas de soi. Envisagé à cette échelle avant tout sous l’angle de la densification urbaine, le développement durable peut en effet être mis en avant pour justifier certaines démolitions. Les deux notions de patrimoine et de développement durable apparaissent cependant plus en phase à travers les projets urbains nantais que dans ceux de la ville d’Angers. Ce que confirme l’élaboration récente des plans locaux d’urbanisme (PLU : alors qu’à Nantes l’intérêt pour les nouvelles possibilités de préservation du patrimoine local est manifeste, du côté d’Angers, c’est la volonté de garder les mains libres pour la densification urbaine qui l’emporte.Heritage and sustainable development, both widely accepted by the contemporary society, seem to proceed from the same logic : it is about better articulating the present and the future, in a logic of transmission and intergenerational solidarity. A cross study of Angers and Nantes, cities confronted with important construction pressure in a context of important population growth, tends to show that the convergence of heritage and sustainable development agendas is not obvious. While heritage is supposed to preserve designated elements, sustainable development can justify some necessary demolition in order to allow urban densification. The two notions of heritage and sustainable development seem however more

    Full Text Available The article presents preliminary results of the biological durability of oil heat treated (OHT alder wood (Alnus glutinosa against pure cultures of rot fungi (Postia placenta and Trametes versicolor in lab conditions. The modification was performed by heating of specimens immersed in soya oil. There were four heating regimes of different duration (6 and 10 hours at final temperature of 180 and 200 ºC. The increase in mass (MI caused by modification and mass loss of wood caused by fungal decay (ML were determined. In addition, the natural durability of alder wood was determined and compared to the natural durability of beech wood as the reference wood species. After modification of alder wood at 200 °C, MI was lower than after treatment at 180 °C. MI was also lower after 10 hours of treatment than after 6 hours of treatment. The results showed significantly increased biological durability of modified alder wood against both tested fungi. The effect of OHT on increasing the biological durability of alder wood was higher against the fungus P. placenta. It seems that the fungus T. versicolor favours the remained oil after modification causing higher mass loss. The results showed that alder wood, thermally modified in soya oil by testing regimens, is not suitable for applications in use classes 3-5.

    Michel Loraux

    2009-06-01

    Full Text Available Ouvrant la réflexion sur les enjeux de la perte massive de la biodiversité, l'article s'appuie sur la question élémentaire de l'importance de la diversité biologique pour l'homme, à la fois sur le plan économique, biologique et éthique. La maîtrise de la nature par l'homme se révèle être une illusion. La réalité étant celle de l'interaction, il est permis de dire que les sociétés humaines agis- sent sur leurs propres conditions en modifiant les équilibres biologiques pour satisfaire leurs besoins, sans pour autant intégrer cette interaction fondamentale dans l'équation d'un rapport viable entre l'homme et la nature. L'approche récente par le biais des analyses des services écologiques constitue à cet égard un progrès sensible. Il aboutit néanmoins au constat de l'impossibilité pour l'humanité de se substituer aux mécanismes naturels permettant de tirer les services de la nature nécessaires à sa survie. Plutôt que de prétendre contrôler et maîtriser la nature à tout prix, l’homme devrait apprendre à se reconnaître comme une partie consciente de la nature et à vivre avec la vie qui l’entoure. Cet apprentissage soulève des défis scientifiques, humains et de gouvernance. L'article prône la nécessité d'une science de la biodiversité intégrée et non plus éclatée, condition essentielle pour l'élaboration de politiques économiques et sociales qui intègrent la viabilité de l'utilisation des ressources naturelles et des services qu'elles procurent.

The MK used was prepared by firing two types of local at temperatures ranging from 700 to 850 ºC. Dry blends of ordinary Portland cement (OPC and varying proportions of MK were mixed with the amount of water required to ensure optimal consistency of the resulting pastes. The specimens were cured at 100% RH for 24 h and then immersed in water for 3, 7, 28, 90 or 180 days. At each test time, the degree of hydration and compressive strength of the hardened cement pastes were measured The findings showed that the most suitable calcination temperature to obtain metakaolin is 700 ºC, while the optimal replacement ratio ranges from 25 to 30%. DTA was used to determine the phases comprising the hydration products forming at the ages studied. Pure OPC and OPC-MK specimens were immersed in 3% NaCl and 5% MgSO4 solutions for 30, 90 and 180 days to measure their durability.

    Statistical analysis and multiple regression were used to determine and quantify the significant hygrothermomechanical variables which influence the tensile durability/life (cycle loading, fatigue) of boron-fiber/epoxy-matrix (B/E) and high-modulus-fiber/epoxy-matrix (HMS/E) composites. The use of the multiple regression analysis reduced the variables from fifteen, assumed initially, to six or less with a probability of greater than 0.999. The reduced variables were used to derive predictive models for compression and intralaminar shear durability/life of B/E and HMS/E composites assuming isoparametric fatigue behavior. The predictive models were subsequently generalized to predict the durability/life of graphite/fiber-r generalized model is of simple form, predicts conservative values compared with measured data and should be adequate for use in preliminary designs.

  15. Durable Catalysts for High Temperature Proton Exchange Membrane Fuel Cells

    DEFF Research Database (Denmark)

    Durability of proton exchange membrane fuel cells (PEMFCs) is recognized as one of the most important issues to be addressed before the commercialization. The failure mechanisms are not well understood, however, degradation of carbon supported noble metal catalysts is identified as a major failure...... corrosion, in turn, triggers the agglomeration of platinum particles resulting in reduction of the active surface area and catalytic activity. This is a major mechanism of the catalyst degradation and a key challenge to the PEMFC long-term durability. High temperature PEMFC, on the other hand, has attached...... the selectivity for platinum loading. Fuel cell durability tests in term of performance degradation were performed with acid doped polybenzimidazole membrane fuel cells at temperatures of up to 160°C. The tests were focused on catalyst degradation by means of a potential cycling protocol. The electrochemical...

    In recent years, the usages of by-products and wastes in industry have become more important. The importance of the sustainable development is also of increasing. The utilizations of wastes, as mineral admixture or fine aggregate, reduce the consumption of the natural resources and improve the durability of concrete. In this study, the effect of the fineness on the high temperature and sulphate resistances of concrete mortar specimens, produced with ground granulated blast-furnace slag (GBFS)replacing cement, is investigated. The compressive and flexural strength test results for all series related to durability effects,exposing temperature and solutions, exposure times for these durability effects, slag content and fineness are discussed. Consequently, the optimum slag contents are determined for producing the sulphate and high temperature resistant mortars.

    The approach employed by NASA Lewis for the long-term durability assessment of the Stirling engine hot-section components is summarized. The approach consists of: preliminary structural assessment; development of a viscoplastic constitutive model to accurately determine material behavior under high-temperature thermomechanical loads; an experimental program to characterize material constants for the viscoplastic constitutive model; finite-element thermal analysis and structural analysis using a viscoplastic constitutive model to obtain stress/strain/temperature at the critical location of the hot-section components for life assessment; and development of a life prediction model applicable for long-term durability assessment at high temperatures. The approach should aid in the provision of long-term structural durability and reliability of Stirling engines.

    We report graphene nanoplatelets (GNPs), which exhibit the advantages of both single-layer graphene and highly graphitic carbon, as a durable alternative support material for Pt nanoparticles for oxygen reduction in fuel cells. Pt nanoparticles are deposited on poly(diallyldimethylammonium chloride) (PDDA)-coated GNP, and characterized with transmission electron microscopy, X-ray diffraction, Raman spectra, and electrochemical tests. Pt/GNP exhibits greatly enhanced electrochemical durability (2-3 times that of Pt/CNT and commercial Etek Pt/C). These are attributed to the intrinsic high graphitization degree of GNP and the enhanced Pt-carbon interaction in Pt/GNP. If considering that GNP can be easily mass produced from graphite, GNP is a promising, low-cost, and durable electrocatalyst support for oxygen reduction in fuel cells. (author)

    Biofuel pellets were prepared from biomass (pine, chestnut and eucalyptus sawdust, cellulose residue, coffee husks and grape waste) and from blends of biomass with two coals (bituminous and semianthracite). Their mechanical properties and combustion behaviour were studied by means of an abrasion index and thermogravimetric analysis (TGA), respectively, in order to select the best raw materials available in the area of study for pellet production. Chestnut and pine sawdust pellets exhibited the highest durability, whereas grape waste and coffee husks pellets were the least durable. Blends of pine sawdust with 10-30% chestnut sawdust were the best for pellet production. Blends of cellulose residue and coals (<20%) with chestnut and pine sawdusts did not decrease pellet durability. The biomass/biomass blends presented combustion profiles similar to those of the individual raw materials. The addition of coal to the biomass in low amounts did not affect the thermal characteristics of the blends.

    Full Text Available Terms and names in architecture may sometimes be powerful in exploring history of ideas. Philology and hermeneutics are discipline of knowledge that utilize this notion in a very throgh and critical way. Inspired by those discipline of knowledge, this musing on `Griya' and `Omah' tries to demonstrate that their meaning is not `house' as many still understand them. Rather, both terms understood by the Jawanese as `any building' constructed. Critical assessment upon old documents named `Kawruh Griya' not only supportive for this understanding among the Javanese, but also provide us with a hint on one of ideals of `what a home is' among the Jawanese. The Javanese once had a notion that to dwell in a house is like sheltering under a shady tree. Since `griya' and `omah' may open our musing up to regions and cultures outside Jawa, this paper will limit its musing within the Jawanese. Abstract in Bahasa Indonesia : Kata, sebutan dan istilah yang digunakan dalam arsitektur terkadang memiliki kemampuan untuk membantu dan menjadi bahan kajian sejarah bagi dunia arsitektur. Kajian filologi dan hermeneutika dengan baik telah memanfaatkan kemampuan tersebut. Tanpa harus memaksakan diri untuk mengikuti dengan ketat bidang pengetahuan tersebut, penelusuran atas arti `griya' dan `omah' ini mencoba untuk mengungkap sebagian kecil dari sejarah arsitektur Jawa. Melalui interpretasi-menerangkan (Poespoprodjo 1987: 194-195 atas arti kedua kata tersebut di dalam berbagai naskah Kawruh Griya, keduanya samasekali tidak memiliki arti: `rumah'. Dengan penelusuran ini ditemukan pula petunjuk yang mengarah pada salah satu gagasan orang Jawa tentang rumah yakni `bagaikan berteduh di bawah pohon'. Meskipun kedua kata tersebut dapat membawa penelusuran ini ke wilayah di luar arsitektur dan masyarakat Jawa, harus diakui bahwa penelusuran ini masih dibatasi pada telusuran internal bahasa Jawa, yakni hanya mengkaji kedua kata tersebut di dalam perjalanan kebahasaan bahasa Jawa

    2017-02-28

    The present invention relates to functionalized polymers including a poly(phenylene) structure. In some embodiments, the polymers and copolymers of the invention include a highly localized concentration of acidic moieties, which facilitate proton transport and conduction through networks formed from these polymers. In addition, the polymers can include functional moieties, such as electron-withdrawing moieties, to protect the polymeric backbone, thereby extending its durability. Such enhanced proton transport and durability can be beneficial for any high performance platform that employs proton exchange polymeric membranes, such as in fuel cells or flow batteries.

    Large majority of superhydrophobic surfaces have very limited mechanical wear robustness and long-term durability. This problem has restricted their utilization in commercial or industrial applications and resulted in extensive research efforts on improving resistance against various types of wear damage. In this review, advances and developments since 2011 in this field will be covered. As such, we summarize progress on fabrication, design and understanding of mechanically durable superhydrophobic surfaces. This includes an overview of recently published diagnostic techniques for probing and demonstrating tribo-mechanical durability against wear and abrasion as well as other effects such as solid/liquid spray or jet impact and underwater resistance. The review is organized in terms of various types of mechanical wear ranging from substrate adhesion, tangential surface abrasion, and dynamic impact to ultrasonic processing underwater. In each of these categories, we highlight the most successful approaches to produce robust surfaces that can maintain their non-wetting state after the wear or abrasive action. Finally, various recommendations for improvement of mechanical wear durability and its quantitative evaluation are discussed along with potential future directions towards more systematic testing methods which will also be acceptable for industry.

    On the basis of the theoretical distinction between self-centeredness and selflessness (Dambrun and Ricard, 2011), the main goal of this research was to develop two new scales assessing distinct dimensions of happiness. By trying to maximize pleasures and to avoid displeasures, we propose that a self-centered functioning induces a fluctuating happiness in which phases of pleasure and displeasure alternate repeatedly (i.e., Fluctuating Happiness). In contrast, a selfless psychological functioning postulates the existence of a state of durable plenitude that is less dependent upon circumstances but rather is related to a person’s inner resources and abilities to deal with whatever comes his way in life (i.e., Authentic–Durable Happiness). Using various samples (n = 735), we developed a 10-item Scale measuring Subjective Fluctuating Happiness (SFHS) and a 13-item scale assessing Subjective Authentic–Durable Happiness (SA–DHS). Results indicated high internal consistencies, satisfactory test–retest validities, and adequate convergent and discriminant validities with various constructs including a biological marker of stress (salivary cortisol). Consistent with our theoretical framework, while self-enhancement values were related only to fluctuating happiness, self-transcendence values were related only to authentic–durable happiness. Support for the distinction between contentment and inner-peace, two related markers of authentic happiness, also was found. PMID:22347202

    This study focused on the development of a new low viscosity automatic transmission fluid (ATF) with enhanced friction durability to meet the needs of new step type automatic transmissions. Recent high fuel prices encourage increased efficiency in the driveline, including the transmission. Reduction in fluid viscosity and wider use of slip control in torque con-verter clutches are two ways to practically improve fuel efficiency. Increased torque and more shifting is seen with a variety of new transmission hardware platforms, such as wet starting clutches, dual clutches and seven - or eight - speed ATs.This suggests the need for enhanced levels of friction durability from the ATF. The new challenge from this hardware for the ATF formulator lies in the need to simultaneously meet the wear, friction durability and torque capacity requirements at low viscosity in a cost- effective manner. This report introduced a new low viscosity fluid that represents a different commercial ATF formulation style. The new chemistry employs a low viscosity for increased fuel economy, while easily doubling the friction durability of current conven-tional ATFs and offering higher torque and better EP.

  14. The Search for Durable Exterior Clear Coatings for Wood

    Directory of Open Access Journals (Sweden)

    Philip D. Evans

    2015-11-01

    Full Text Available The goal of a durable exterior clear coating has eluded generations of coatings technologists, despite long-standing desire amongst the public for such a coating. The journey towards this goal initially focused on modifications to coating formulation, but took a completely different direction when it was found that a UV-transparent silicone clear coating on wood modified with chromic acid met consumer expectations of coating durability. This finding sparked world-wide interest in wood pre-treatments as a way of enhancing the durability of clear coatings. This interest initially focused on transition metal compounds, but has now shifted in the direction of organic and inorganic photostabilizers or even more drastic pre-treatments. Pre-treatments that dimensionally stabilize wood, protect it from microbial degradation and photostabilize lignin, when combined with flexible, photostable, coatings provide the next way-stop on the journey towards achieving the goal of durable exterior clear coatings for wood. This paper reviews this journey, drawing upon our research and that of other groups who have focused on this elusive goal.

    Full Text Available In this article we demonstrated the study results of durability quality of concrete containing waste solar PV cells. The study used alkali activator to improve the activity of alkali-activated materials in solar PV cells so as to replace Portland cement as binder in concrete. By using sodium hydroxide as an alkali-activator, a high-pH environment is generated to excite the binding characteristics of alkali-activated materials in solar PV cells, and thus develops better durability of the mixes. The conclusions were made on effect of this cement replacement. As a result, we identified the durability for those of 16 concrete specimens predefined and made to consider various possible control factors. The conclusions also depicted that all experiments but the drying shrinkage may be helpful with the suitable use of control factors as far as concerning the recycled solar PV cells for mixing in concrete. In other words, the durability quality of concrete may be partially unacceptable of containing solar PV cells.

Analisis data mengunakan metode analisis Miles dan Huberman, dengan melalui tiga prosedur yaitu reduksi data, penyajian data dan menarik kesimpulan/verifikasi. Sedangkan keabsahan menggunakan teknik berdasarkan atas kriteria derajat kepercayaan, keteralihan, ketergantungan, dan kepastian suatu data. Tuntutan menghadapi  implementasi Otonomi Daerah mengandung arti pentingnya Pemerintah Daerah memperhatikan kemampuan “self suporting” dalam bidang keuangan. Sumber pendapatan daerah tidak hanya di peroleh dari Pendapatan Asli Daerah, tetapi juga berupa pemberian bagi hasil dari penerimaan Pemerintah Pusat. Diantara sumber penerimaan tersebut adalah Pajak Bumi dan Bangunan. Dalam Undang-undang Nomor 25 Tahun 1999 Tentang perimbangan keuangan antara Pemerintah Pusat  dan Daerah, diantaranya dijelaskan bahwa sumber penerimaan daerah dalam penyelenggaraan desentralisasi berasal dari dana perimbangan penerimaan Pajak Bumi dan Bangunan disamping pemberian Dana Alokasi Umum dan Alokasi Khusus. Langkah Implementasi dari pelaksanan pemungutan Pajak Bumi dan Bangunan tersebut dilakukan Departemen Keuangan melalui Kantor Pelayanan Pajak Bumi dan Bangunan, sedang Pemerintah daerah menerima pelimpahan penagihan pada Sektor Perkotaan dan Sektor Pedesaan. Meskipun telah ada pelimpahan kewenangan kepada daerah, akan tetapi pelimpahan kewenangan tersebut terbatas pada mekanisme penagihan saja, sedang implementor yang menyangkut masalah administrasi masih berada pada Kantor Pelayan Pajak Bumi dan Bangunan. Kondisi demikian ini ditambah dengan kurangnya koordinasi antara unit organisasi pelaksana menyebabkan setiap tahun terjadi tunggakan.

    Full Text Available Rapid change of environment is an external force that causes the organization to transform. Fundamentally, the main purpose of the transformation is to change the organizational structure to be more flexible and competitive with fewer hierarchial levels, managers, and employees. The transformation needs to be radical, causing resistance from the organization's members. Their resistance can cause the transformation to fail, therefore organization must find ways to lessen this resistance. First, organization must learn about the diversity of its members' cultures and values. Second, organization must build its own organizational culture which can support the success of the transformation, by communicating it with the members of the organization. To support organizational culture building efforts, it needs changes in human resources practices, especially recruitment and selection. Abstract in Bahasa Indonesia : Perubahan yang cepat dalam lingkungan merupakan kekuatan eksternal yang mengakibatkan transformasi dalam sebuah organisasi. Pada dasarnya, tujuan utama dari transformasi tersebut adalah merubah struktur organisasi agar menjadi lebih fleksibel dan mampu bersaing, dengan tingkat structural yang sedikit, serta jumlah manajer dan karyawan yang lebih kecil. Transformasi tersebut harus menyeluruh, dan hal ini dapat menyebabkan resistensi dari para anggota organisasi yang memperhambat perubahan tersebut. Resistensi itu bisa menyebabkan perubahan tersebut batal, oleh karena itu organisasi harus mencari jalan untuk mengurangi hambatan-hambatan tersebut. Pertama, organisasi harus belajar keanekaragaman dari budaya dan nilai anggotanya. Kedua, organisasi harus mengembangkan budaya organisasi sendiri melalui komunikasi yang baik dengan anggotanya. Untuk mendukung usaha mengembangkan budaya organisasi, harus ada perubaban pada kebijakan sumber daya manusia, terutama dalam rekrutmen dan seleksi karyawan. Kata kunci: transformasi, resistensi, budaya

  4. Enhanced durability and reactivity for zinc ferrite desulfurization sorbent

    Energy Technology Data Exchange (ETDEWEB)

    Berggren, M.H.; Jha, M.C.

    1989-10-01

    AMAX Research Development Center (AMAX R D) investigated methods for enhancing the reactivity and durability of zinc ferrite desulfurization sorbents. Zinc ferrite sorbents are intended for use in desulfurization of hot coal gas in integrated gasification combined cycle (IGCC) or molten carbonate fuel cell (MCFC) applications. For this program, the reactivity of the sorbent may be defined as its sulfur sorption capacity at the breakthrough point and at saturation in a bench-scale, fixed-bed reactor. Durability may be defined as the ability of the sorbent to maintain important physical characteristics such as size, strength, and specific surface area during 10 cycles of sulfidation and oxidation. Two base case sorbents, a spherical pellet and a cylindrical extrude used in related METC-sponsored projects, were used to provide a basis for the aimed enhancement in durability and reactivity. Sorbent performance was judged on the basis of physical properties, single particle kinetic studies based on thermogravimetric (TGA) techniques, and multicycle bench-scale testing of sorbents. A sorbent grading system was utilized to quantify the characteristics of the new sorbents prepared during the program. Significant enhancements in both reactivity and durability were achieved for the spherical pellet shape over the base case formulation. Overall improvements to reactivity and durability were also made to the cylindrical extrude shape. The primary variables which were investigated during the program included iron oxide type, zinc oxide:iron oxide ratio, inorganic binder concentration, organic binder concentration, and induration conditions. The effects of some variables were small or inconclusive. Based on TGA studies and bench-scale tests, induration conditions were found to be very significant.

    Full Text Available Muhammad was born in Mecca between AD 570 and 580 in the Banu Hashims,a reputable family of Quraysh. In Mecca, Muhammad is portrayed as a privatecitizen, as he had to limit himself and adapt his behavior to face the situationduring jahiliyyah era. While, in Medina he governed the community and guidedthem in religious life. His arrival in Medina has significant contribution towardhis role as political leader. His power in this city had protected himself and hisfollowers from violent opposition of the Quraysh. The doctrines he employedin politics were inseparable from the religious values rooted from the Quran.Through his innovation and skillful diplomacy, he had converted the peopleof Mecca and Medina into brighter Arab civilization. Such a positive changereflected his monumental accomplishment for the people.Muhammad lahir di kota Makkah antara tahun 570 sampai 580 Masehi dikeluarga Bani Hasyim, suku Quraisy terkemuka di Arab. Di kota Makkah,Muhammad dianggap sebagai masyarakat biasa, sebab ia harus membatasidirinya dan menyesuaikan prilakunya dalam menghadapi keadaan yangterjadi pada zaman jahiliyyah. Sedangkan di Madinah, ia dianggap sebagaipemimpin masyarakat dan menjadi pembimbing umat dalam hidup beragama.Kedatangannya di Madinah juga memberikan konstribusi besar pada perannyasebagai pemimpin politik. Kekuasaan di kota ini sangat membantu dirinya danpara pengikutnya dari kerasnya kelompok oposisi Quraisy. Doktin-doktrin yangdigunakan Muhammad dalam dunia politik juga tidak lepas dari nilai-nilaiagama yang bersumber dari al Quran. Dengan kreatifitas dan inovasinya dalammemimpin, Muhammad mampu mengarahkan masyarakat Makkah dan Madinah menuju kebangkitan peradaban bangsa Arab yang lebih cemerlang.Kondisi yang semakin membaik tersebut, tidak lain merupakan sebuah karyadan jasa monumental yang telah diukir oleh Muhammad untuk umatnya.

Kesejahteraan Masyarakat sesungguhnya dapat dilihat dari tingkat pemenuhan hak EKOSOB (Ekonomi, Sosial dan Budaya, ketiga poin tersebut merupakan bagian kecil indikator kesejahteraan rakyat. Bersama-sama dengan Hak Sipil, hak ekosob telah diakui secara internasional sebagai bagian dari the international bill of human rights. Kerangka hukumnya menjadi semakin jelas setelah hak-hak tersebut dituangkan dalam perjanjian multilateral yang tertuang dalam Covenan on Economic, Social and Cultural Rights (selanjutnya disingkat CESCR, yang disahkan oleh Majelis Umum PBB pada tahun 1966 sebagai pelaksanaan dari prinsip-prinsip yang dimuat dalam DUHAM 1948. Kewenangan negara yang dalam hal ini adalah pemerintah untuk menjamin hak-hak ekonomi, sosial dan budaya di indonesia dirasa tidak memenuhi hasil yang memadai sehingga dapat dilihat dengan masih banyaknya pengangguran, kemiskinan, dan rendahnya tingkat pendidikan warga negara. Selain itu, tingkat korupsi di Indonesia masih sangat tinggi dibanding negara-negara lain yang menyebabkan tingkat pelanggaran hak EKOSOB di Indonesia masih sangat tinggi.

      Abstrak Perdebatan tidak berkesudahan terus mewarnai perbincangan dan praktek kebebasan beragama, terutama mengenai kata “kebebasan” yang dilekatkan pada agama dan kepercayaan. Jika “kebebasan” dimaknai sebagai kemerdekaan, apa lantas berarti tidak adanya batasan terhadap kemerdekaan tersebut, dalam arti bahwa kebebasan tersebut bersifat mutlak. Atau barangkali “kebebasan” di sini dimaknai sebagai kebebasan relatif yang membuka kemungkinan perumusan definisi dan ruang lingkup yang jelas. Penulis berpandangan bahwa kebebasan beragama bukan kebebasan mutlak yang tidak menuntut pendefinisian, perumusan ruang-lingkup serta norma norma, dan pengaturan. Kebebasan mutlak pada taraf yang demikian bukan kebebasan yang bermakna sebenarnya, namun dapat berarti sebuah keadaan anarki dan anomi. Kebebasan beragama adalah kebebasan relatif yang menuntut adanya penjelasan tentang definisi, ruang lingkup, norma-norma, dan batasan-batasannya.

    Full Text Available Abstract: Sufism in the eras of globalization and information often faces considerable challenges. The function and role of religion in modern life have in some aspects diminished, including sufism because it is claimed to have played no or less role in resolving problems nor stimulating social change. As one of Islamic traditions, sufism makes ihsan as its essential teaching. By this concept, sufism encourages humans to pray to God wholeheartedly. Sufism is now required to show its own existence and function by making fundamental contribution for modern life, an era which differ socio-culturally from the one when sufism firstly emerged. Sufism thus needs to adapt itself to the changes in the era of information and globalization so that it will remain relevant and suitable for human progress. Sufism needs to release itself from its exclusivism and to avoid being trapped in its own logic, namely speculative-trancendentalism Abstrak: Tasawuf di era globalisasi dan informasi seperti saat ini tengah menghadapi tantangan yang sangat berat. Kehidupan modern sudah sampai pada taraf tidak lagi mempercayai fungsi dan peran agama, termasuk di dalamnya tasawuf, sebagai ‘sesuatu’ yang dapat memberikan solusi bagi perubahan sosial. Sebagai manifestasi paripurna dari ajaran Islam, tasawuf berintikan pada konsep Ihsān yang mengajarkan untuk beribadah kepada Sang Pencipta secara ikhlas. Untuk menunjukkan eksistensinya, tasawuf dituntut peran aktifnya secara konstruktif-solutif terhadap berbagai kebutuhan manusia modern yang amat berbeda dengan setting maupun struktur masyarakat pada saat tasawuf “dilahirkan” pada zamannya. Tasawuf dituntut untuk memerlukan “baju” baru di era informasi yang kerap berubah ini, agar tetap realible dan suitable dengan kemajuan zaman. Hal itu dapat dilakukan dengan berusaha “keluar” dari eksklusifismenya dengan meminjam tradisi filsafat analitik pasca positivisme dan tradisi eksistensialis serta dinamika filsafat

    Full Text Available ABSTRAK EIGRP (Enhanced Interior Gateway Routing Protocol dan OSPF (Open Shortest Path Fisrt adalah routing protokol yang banyak digunakan pada suatu jaringan komputer. EIGRP hanya dapat digunakan pada perangkat Merk CISCO, sedangkan OSPF dapat digunakan pada semua merk jaringan. Pada penelitian ini dibandingkan delay dan rute dari kedua routing protokol yang diimplementasikan pada topologi Ring dan Mesh. Cisco Packet Tracer 5.3 digunakan untuk mensimulasikan kedua routing protokol ini. Skenario pertama adalah perancangan jaringan kemudian dilakukan pengujian waktu delay 100 kali dalam 5 kasus. Skenario kedua dilakukan pengujian trace route untuk mengetahui jalur yang dilewati paket data lalu memutus link utama. Pada skenario kedua juga dilakukan perbandingan nilai metric dan cost hasil simulasi dengan perhitungan rumus. Skenario ketiga dilakukan pengujian waktu konvergensi untuk setiap routing protokol pada setiap topologi. Hasilnya EIGRP lebih cepat 386 µs daripada OSPF untuk topologi Ring sedangkan OSPF lebih cepat 453 µs daripada EIGRP untuk topologi Mesh. Hasil trace route menunjukan rute yang dipilih oleh routing protokol yaitu nilai metric dan cost yang terkecil.

    Varlet, Madeleine

    Le recours aux modeles et a la modelisation est mentionne dans la documentation scientifique comme un moyen de favoriser la mise en oeuvre de pratiques d'enseignement-apprentissage constructivistes pour pallier les difficultes d'apprentissage en sciences. L'etude prealable du rapport des enseignantes et des enseignants aux modeles et a la modelisation est alors pertinente pour comprendre leurs pratiques d'enseignement et identifier des elements dont la prise en compte dans les formations initiale et disciplinaire peut contribuer au developpement d'un enseignement constructiviste des sciences. Plusieurs recherches ont porte sur ces conceptions sans faire de distinction selon les matieres enseignees, telles la physique, la chimie ou la biologie, alors que les modeles ne sont pas forcement utilises ou compris de la meme maniere dans ces differentes disciplines. Notre recherche s'est interessee aux conceptions d'enseignantes et d'enseignants de biologie au secondaire au sujet des modeles scientifiques, de quelques formes de representations de ces modeles ainsi que de leurs modes d'utilisation en classe. Les resultats, que nous avons obtenus au moyen d'une serie d'entrevues semi-dirigees, indiquent que globalement leurs conceptions au sujet des modeles sont compatibles avec celle scientifiquement admise, mais varient quant aux formes de representations des modeles. L'examen de ces conceptions temoigne d'une connaissance limitee des modeles et variable selon la matiere enseignee. Le niveau d'etudes, la formation prealable, l'experience en enseignement et un possible cloisonnement des matieres pourraient expliquer les differentes conceptions identifiees. En outre, des difficultes temporelles, conceptuelles et techniques peuvent freiner leurs tentatives de modelisation avec les eleves. Toutefois, nos resultats accreditent l'hypothese que les conceptions des enseignantes et des enseignants eux-memes au sujet des modeles, de leurs formes de representation et de leur approche

    Fernandez, Nicolas

    Les representants des secteurs industriels et les, milieux professionnels en Amerique du Nord reprochaient aux universites de former des ingenieurs avec peu d'experience pratique en resolution de problemes et en conception. Quelques programmes de genie ont alors mis en place le travail en equipe dans l'apprentissage par projets. Beaucoup d'ecrits font valoir les benefices de l'apprentissage par projets sur la motivation des etudiants. Or, ces benefices commencent a peine a faire l'objet de recherches visant a produire des donnees probantes a ce sujet. Les travaux sur la motivation en contexte d'apprentissage et les modeles theoriques developpes sont issus d'environnements d'apprentissage marques par l'enseignement magistral. Le modele de la valeur attendue de la tache (Eccles et Wigfield, 1995; Neuville, 2004) et le modele du systeme-groupe (St-Arnaud, 2008) ont ete retenus pour mesurer les effets du travail en equipe dans l'apprentissage par projets sur la motivation. La recherche visait aussi a approfondir et a nuancer la comprehension de la motivation des etudiants universitaires apprenant en contexte innovant. Les sujets constituent des etudiants (n=100) travaillant sur des projets d'integration au cours des trois sessions initiales du programme de genie mecanique d'une universite canadienne. L'analyse de regression multiple revele que les construits de la motivation expliquent un tiers de la variance de l'engagement academique dans la realisation du projet d'integration. Les perceptions de l' "expectancy", de la valeur intrinseque et utilitaire sont les determinants principaux de l'engagement des etudiants. L'analyse de variance multivariee a mesures repetees indique que la motivation des etudiants pour le travail sur les projets d'integration a augmente au cours des trois sessions initiales du parcours de formation. Finalement, malgre l'absence d'interaction significative entre les variables de motivation et de l'equipe, les reponses des sujets indiquent une

    Full Text Available Penelitian mengenai penggunaan asam sitrat sebagai agen pengikat alami masih relatif sedikit. Oleh karena itu penelitian ini difokuskan pada pengaruh jumlah asam sitrat dan suhu pengempaan terhadap sifat papan partikel bambu, termasuk ketahanannya terhadap serangan rayap kayu kering. Bahan penelitian adalah partikel bambu petung. Komposisi kimia bahan baku bambu diuji untuk kadar ekstraktif, holoselulosa, lignin, dan alfa selulosa. Faktor pada penelitian ini adalah jumlah asam sitrat (0 - 40% berdasarkan berat kering udara partikel dan suhu pengempaan (200 oC dan 220 oC. Sifat fisika dan mekanika papan partikel diuji berdasarkan standar pengujian JIS A 5908. Analisis menggunakan Fourier transform infrared spectroscopy (FTIR juga dilakukan untuk mengetahui perubahan gugus ester pada berbagai jumlah asam sitrat dan suhu pengempaan. Pengujian ketahanan terhadap serangan rayap kayu kering juga dilakukan dengan menghitung nilai pengurangan berat dan mortalitas rayap setelah 6 minggu. Hasil pengujian menunjukkan bahwa interaksi kedua faktor berpengaruh nyata terhadap nilai pengembangan tebal, penyerapan air, modulus elastisitas dan modulus patah. Intensitas gugus C=O yang ditunjukkan pada puncak 1720 cm-1 semakin bertambah besar seiiring dengan semakin banyaknya jumlah asam sitrat, yang menyebabkan kekuatan perekatan dan stabilitas dimensi papan partikel menjadi semakin kuat. Kondisi optimum pada penelitian ini adalah papan partikel dengan penambahan jumlah asam sitrat 20 % pada suhu pengempaan 200 oC dengan kualitas yang dapat memenuhi standar JIS A 5908 tipe 8. Penambahan asam sitrat dapat meningkatkan mortalitas rayap kayu kering secara nyata. Penambahan 20 % asam sitrat pada suhu pengempaan 200 oC menghasilkan nilai pengurangan berat 0,9 % dan mortalitas rayap 57 %.

  19. Evolutionary model of an anonymous consumer durable market

    Kaldasch, Joachim

    2011-07-01

    An analytic model is presented that considers the evolution of a market of durable goods. The model suggests that after introduction goods spread always according to a Bass diffusion. However, this phase will be followed by a diffusion process for durable consumer goods governed by a variation-selection-reproduction mechanism and the growth dynamics can be described by a replicator equation. The theory suggests that products play the role of species in biological evolutionary models. It implies that the evolution of man-made products can be arranged into an evolutionary tree. The model suggests that each product can be characterized by its product fitness. The fitness space contains elements of both sites of the market, supply and demand. The unit sales of products with a higher product fitness compared to the mean fitness increase. Durables with a constant fitness advantage replace other goods according to a logistic law. The model predicts in particular that the mean price exhibits an exponential decrease over a long time period for durable goods. The evolutionary diffusion process is directly related to this price decline and is governed by Gompertz equation. Therefore it is denoted as Gompertz diffusion. Describing the aggregate sales as the sum of first, multiple and replacement purchase the product life cycle can be derived. Replacement purchase causes periodic variations of the sales determined by the finite lifetime of the good (Juglar cycles). The model suggests that both, Bass- and Gompertz diffusion may contribute to the product life cycle of a consumer durable. The theory contains the standard equilibrium view of a market as a special case. It depends on the time scale, whether an equilibrium or evolutionary description is more appropriate. The evolutionary framework is used to derive also the size, growth rate and price distribution of manufacturing business units. It predicts that the size distribution of the business units (products) is lognormal

    Abstract Background: The durability of cervical disc arthroplasties (CDA) may vary significantly because of different designs and implanting techniques of the devices. Nevertheless, the comparative durability remains unknown. Objectives: We aimed to assess the durability of CDAs in at least 2-year follow-up. We analyzed the classifications and causes of secondary surgical procedures, as well as the structural designs of the devices that might influence the durability. Methods: PubMed, Medline, Embase, and Cochrane Central Register of Controlled Trials were searched from the inception of each database to September 2015 using the following Keywords: “cervical disc replacement” OR “cervical disc arthroplasty” AND “randomized controlled trial (RCT).” Publication language was restricted to English. The primary outcome was the rate of secondary surgical procedures following CDA or anterior cervical decompression and fusion (ACDF). Pairwise meta-analysis and a Bayesian network meta-analysis were carried out using Review Manager v5.3.5 and WinBUGS version 1.4.3, respectively. Quality of evidence was appraised by Grading of Recommendations Assessment, Development and Evaluation methodology. Results: Twelve RCTs that met the eligibility criteria were included. Follow-up ranged from 2 years to 7 years. A total of 103 secondary surgical procedures were performed. The most frequent classification of secondary surgical procedures was reoperation (48/103) and removal (47/103). Revision (3/103) and supplementary fixation (2/103) were rare. Adjacent-level diseases were the most common cause of reoperations. The rates of secondary surgical procedures were significantly lower in Mobi-C, Prestige, Prodisc-C, Secure-C group than in ACDF group. No significant difference was detected between Bryan, PCM, Kineflex-C, Discover, and ACDF. Mobi-C, Secure-C, and Prodisc-C ranked the best, the second best, the third best, respectively. Conclusions: We concluded that Mobi-C, Secure

    Full Text Available La région durable doit se positionner dans un contexte d'ouverture et de concurrence territoriale. À défaut de pouvoir influencer notablement les paramètres du changement global, les acteurs sont appelés à les anticiper et à les prendre en compte dans leurs stratégies. Ils sont invités à élaborer une vision prospective qui renouvelle leurs rapports au territoire dans la perspective du développement durable. C’est dans cet esprit que l’exercice de prospective a été développé. La méthode, présentée ici pour la région Guadeloupe, intègre à la fois les tendances lourdes liées à l’environnement contextuel et les tendances lourdes spécifiques au territoire. Au-delà d’un scénario au fil de l’eau qui peut conduire à une marginalisation de la région, deux visions du devenir guadeloupéen sont analysées vers une inacceptable et une souhaitable.Sustainable Region should position itself in a context of openness and territorial competition.

D’autre part, elle s’intéresse à l’appropriation de ces concepts par les agriculteurs. Pour ce faire, des entretiens semi-directifs ont été menés auprès de ces acteurs en prise avec ces questions de « durabilité ». L’objectif est de mettre en parallèle ces deux formes de contenu et de mettre en lumière les représentations sociales liées à ces objets en partant du postulat que ces dernières, en tant que forme de connaissance socialement élaborées, sont un guide pour l’action et que celles-ci se forment, se transmettent, et évoluent au cœur de la communication (Moscovici, 1976.This study focuses on the meaning of the concepts of sustainable development and sustainable agriculture. First, this study deals with a content analysis of their circulation in the regional papers (specialized in agriculture and popular newspaper. Second, it is interested in the appropriation of theses concepts farmers. Semi-structured interviews were carried out with these stakeholders concerned with these issues. The aim of the study is to compare these two content analyses and to highlight the social representations of these concepts. We postulate that these representations are a form of knowledge which is socially constructed. They are a guide to action and that they take shape, they are transmitted and they evolve in the heart of communication (Moscovici, 1976.

    Full Text Available En remplaçant la part des cotisations sociales à la charge de l’employeur par un éco-impôt sur le capital polluant, l’Etat peut inciter les entreprises à investir dans les trajectoires technologiques de la durabilité. Cet article expose un modèle macroéconomique à trois facteurs qui montre comment la fixation conjointe et combinée du taux de cotisations sociales et du taux d'éco-impôt peut assurer la stabilité globale des prix, garantir la neutralité budgétaire et conserver en l’état la compétitivité prix. Contrôlée par le ministère du développement durable, la déformation de la fonction de production provoquée par une fiscalité directe favorable au capital non polluant et au travail augmente le volume de l’emploi et améliore la qualité environnementale sans détériorer la compétitivité ni déséquilibrer les comptes sociaux.Replacing the welfare cost by an eco-taxation based on polluting capital can incite companies to invest in the technological trajectories for sustainability. This paper proposes a macroeconomic three factors model in which the jointed and combined determination of welfare cost and eco-taxation rates can maintain the global price stability, guarantees the budget balance of fiscal transfers and keeps the state of the competitiveness price as it was before. Controlled by the ministry of sustainable development, the deformation of the function of production, caused by a direct tax system favorable to the non-polluting capital and to the labour, increases the employment and improves the environmental quality without negative effects on competitiveness and social accounts.

    Full Text Available Suhu dan kelembaban merupakan dua objek pengukuran yang acapkali terdapat di dalam sistem akuisisi data. Terdapat banyak piranti sensor yang berfungsi untuk mengukur dua objek tersebut dan akurasi merupakan salah satu parameter yang dapat digunakan untuk memilihnya. DHT11 dan DHT22 adalah sensor seri DHT dari Aosong Electronics yang dapat melakukan pengukuran suhu dan kelembaban secara serempak dengan keluaran digital. Informasi tentang akurasi terdapat di dalam lembar data keduanya. Kendati pun demikian informasi tersebut tidak menggambarkan kondisi sesungguhnya saat dioperasikan pada lokasi maupun platform tertentu. Tujuan dari penelitian ini adalah untuk membandingkan akurasi dari DHT11 dan DHT22 dalam pengukuran suhu dan kelembaban saat dioperasikan di dalam maupun di luar ruangan, menggunakan platform ATMEL AVR dan Arduino. Berdasarkan pengujian yang telah dilakukan, DHT22 memiliki akurasi yang lebih baik daripada DHT11 dengan galat relatif pengukuran suhu 4% dan kelembaban 18%. DHT11 sebaliknya memiliki rentang galat yang lebih lebar sebesar 1 – 7% dan 11 – 35%, masing-masing untuk pengukuran suhu dan kelembaban. Perbedaan lokasi dan platform tidak memberikan pengaruh pada hasil pengukuran. Galat pengukuran kelembaban yang masih di atas 10% menunjukkan perlunya kalibrasi ulang. Di masa mendatang, selain akurasi, kepresisian juga perlu diuji menggunakan penghitungan simpangan baku pada hasil-hasil pengukuran.

    There is a strong need to decrease the amount of Pt electrocatalyst used in fuel cells and increase its durability for transportation application. Conventional strategies include Pt nanocrystals and Pt alloy with well-controlled structures, durable carbon support, non-carbon support, etc. We have developed the so-called “metal-metal oxide-carbon” triple junction concept to stabilize Pt and protect carbon from corrosion. It also improved the activity of Pt. The good performance was not achieved in fuel cell test mainly because of the transport issue due to the use of 2D graphene. In this project, our main goal is to demonstrate the concept in fuel cell device test using 3D porous graphene as support so that the transport issue could be addressed.

    Full Text Available This paper presents a framework to study how changes in exogenous parameters, such as quality levels of new and used durables, affect the composition of durable good stocks. Our model extends the previous literature by including the endogeneity of prices and qualities. Our results could be applied to evaluate policies for controlling the externality level associated with the use and quality of durable goods in the long-term. We studied the characterization of the demand under a special situation: the consumer can choose the operation and/or maintenance level in the period the durable goods are new, which determines the quality levels for the subsequent periods. Comparative statics is performed to analyze the effects of exogenous variable change on the composition of durable stocks, and thus its impact on the externality level associated with each quality level. Contrary to most expectations, we provide an example in which the regulator imposes stricter quality standards for new durables to decrease negative externality associated with the use of durables. In this example, the comparative static results show that policies focusing only on new durable externality control may turn out to increase total externality, since stocks of older vintages may increase.Este trabalho apresenta uma estrutura para analisar as mudanças de parâmetros exógenos, tais como níveis de qualidade de bens duráveis novos e usados sobre a composição de estoques de bens duráveis.

    Exterior sheathing insulation is an effective strategy in increasing the overall R-value of wall assemblies; other benefits include decreasing the effects of thermal bridging and increasing the moisture durability of the built assembly. Vapor-permeable exterior insulation, such as mineral board or expanded polystyrene foam, are one such product that may be used to achieve these benefits. However,uncertainty exists on the effects of inward driven moisture and the interaction of increased sheathing temperatures on the moisture durability of the edifice. To address these concerns, Building Science Corporation (BSC) conducted a series of hygrothermal models for cities representing a range of different climate zones. This report describes the research project, key research questions, and theprocedures utilized to analyse the problems.

    We developed a simple and inexpensive method to prepare the superhydrophobic and oleophobic copper meshes with rough structures fabrication and chemical modification. The achieved surfaces displayed liquid-repellent toward water and several organic liquids (such as hexadecane), which possessed much lower surface tension than that of water. Liquid repellency of the fabricated superhydrophobic copper mesh was demonstrated by visible experiment results and contact angle measurements. Even if the superhydrophobic copper mesh was rolled up, it still kept the superhydrophobicity. The mechanical durability was investigated by finger touch and mechanical abrasion tests. The results indicated that the copper mesh can maintain its superhydrophobicity against an abrasion length of 300 cm under a high pressure (77.2 kPa). The superhydrophobicity and oleophobicity, combined with mechanical durability, would promote the superhydrophobic surface to practical application in industry in the future.

    Full Text Available Le développement est considéré comme durable lorsqu’il permet aux générations actuelles de satisfaire à leurs besoins sans compromettre la capacité des générations futures à satisfaire les leurs. Il faut pour cela que les générations futures détiennent au moins autant de ressources, sous la forme de capital ou de potentialités diverses, que la génération actuelle. Lorsqu’on considère la dimension sociale du développement durable, se pose alors la question du transfert des acquis ou potentialités d’une génération à l’autre. Ces potentialités prennent de multiples formes: capital humain (éducation, santé, capital social (liens sociaux, capacité à utiliser les potentialités disponibles, etc. Plus généralement, la durabilité sociale du développement demande d’aborder les conditions d’une transmission équitable des "capacités à faire et à être" (plus simplement "capabilités" d’une génération à l’autre. On attend donc d’un développement socialement durable qu’il protège les potentialités, renforce les capacités d’une génération donnée, et facilite leur transfert à la génération suivante. Cela implique d’examiner ce qui empêche la constitution de potentialités (trappes à pauvreté, l’amélioration des capacités (exclusion sociale et vulnérabilité et la transmission inter-générationnelle (inégalités. Dès lors, dans le cadre d’une éthique de la responsabilité, des principes de précaution sociale adéquats pourraient guider l’élaboration des politiques publiques.Sustainable development allows the current generation to satisfy its needs without compromising the capacity of future generations to satisfy theirs. This implies that future generations should have in hand at least as many resources, in terms of capital or various potentialities, than the current generation.

    Full Text Available L’accès des jeunes agriculteurs aux ressources foncières est peu pris en compte dans les débats sur la durabilité des agricultures dans les pays du Sud. Les dispositifs de transfert foncier vers cette catégorie sociale, importante sur le plan démographique, restent rares et peu opérants. Nous montrons ici, à travers l’étude de trois situations irriguées en Tunisie, que des transferts de terres vers les jeunes existent mais qu’ils s’effectuent souvent de manière informelle, et plus à travers différentes formes de faire-valoir indirect (FVI qu’à travers un transfert de propriété. Nous analysons le rôle joué par le FVI dans la flexibilité des systèmes fonciers locaux et nous discutons le caractère durable des dynamiques qui en découlent. Nous discutons enfin le défi majeur que représente pour les décideurs politiques en Tunisie et au Maghreb l’inscription de cette agriculture informelle dans une perspective durable. Approfondir les connaissances sur le rôle joué par le FVI dans la flexibilité des systèmes fonciers et agraires locaux peut fournir des pistes de réflexion pour mieux valoriser des ressources en terre et en eau très disputées en Tunisie, et ailleurs au Maghreb.

  10. Novel Arrangements for High Performance and Durable Dielectric Elastomer Actuation

    Directory of Open Access Journals (Sweden)

    Runan Zhang

    2016-07-01

    Full Text Available This paper advances the design of Rod Pre-strained Dielectric Elastomer Actuators (RP-DEAs in their capability to generate comparatively large static actuation forces with increased lifetime via optimized electrode arrangements. RP-DEAs utilize thin stiff rods to constrain the expansion of the elastomer and maintain the in-plane pre-strain in the rod longitudinal direction. The aim is to study both the force output and the durability of the RP-DEA. Initial design of the RP-DEA had poor durability, however, it generated significantly larger force compared with the conventional DEA due to the effects of pre-strain and rod constraints. The durability study identifies the in-electro-active-region (in-AR lead contact and the non-uniform deformation of the structure as causes of pre-mature failure of the RP-DEA. An optimized AR configuration is proposed to avoid actuating undesired areas in the structure. The results show that with the optimized AR, the RP-DEA can be effectively stabilized and survive operation at least four times longer than with a conventional electrode arrangement. Finally, a Finite Element simulation was also performed to demonstrate that such AR design and optimization can be guided by analyzing the DEA structure in the state of pre-activation.

  11. Use of recycled fine aggregate in concretes with durable requirements.

    Zega, Claudio Javier; Di Maio, Angel Antonio

    2011-11-01

    The use of construction waste materials as aggregates for concrete production is highly attractive compared to the use of non-renewable natural resources, promoting environmental protection and allowing the development of a new raw material. Several countries have recommendations for the use of recycled coarse aggregate in structural concrete, whereas the use of the fine fraction is limited because it may produce significant changes in some properties of concrete. However, during the last decade the use of recycled fine aggregates (RFA) has achieved a great international interest, mainly because of economic implications related to the shortage of natural sands suitable for the production of concrete, besides to allow an integral use of this type of waste. In this study, the durable behaviour of structural concretes made with different percentage of RFA (0%, 20%, and 30%) is evaluated. Different properties related to the durability of concretes such as absorption, sorptivity, water penetration under pressure, and carbonation are determined. In addition, the results of compressive strength, static modulus of elasticity and drying shrinkage are presented. The obtained results indicate that the recycled concretes have a suitable resistant and durable behaviour, according to the limits indicated by different international codes for structural concrete.

    The performance of concrete with a new admixture MX was studied by using the freeze-thaw cycle, permeability and chemical attack test. The experimental results show that MX improves the durability of concrete. Within the optimum proportion ranges from 0.1%to 1%,the compressive strength of concrete after freeze-thaw is increased by 20%-50%,and Young's modulus can be increased by 3.76-5.64 times.The strength and weight loss of concrete with 0.4%MX are respectively decreased by 28% and 60% after hydrochloric acid attack.The strength and weight loss of concrete with 0.4% MX are decreased by 5%-20% after sulfuric acid and sodium sulfate attack.The permeability of concrete with 1% MX at 28 days can be decreased by more than 30%. The investigation of the negative temperature property of MX and analysis on concrete composition and microstructure by MIP reveal that the heat conduction is resisted and the freezing procedure of solution in concrete pore is retarded due to the adding of MX. Moreover,the pore structure of concrete with MX is improved, thus improving the durability. Based on this study, a resistance model of MX to block the heat and mass transference was proposed, and the mechanism of durability improvement of concrete with MX was explained.

    Full Text Available Self Compacting Concrete (SCC is a new innovation in technology that can flow readily into place under its own self weight and fill corner areas of reinforcement structures without the need to vibrate and without segregation of its constitute. The problem of durability of concrete structures due to inadequate compaction by skilled workers has become a source of concern globally. The shortage of skilled manpower, noise and vibration of equipment on construction sites has led to the development of self compacting concrete. This paper presents an experimental study on the durability properties of Self Compacting Concrete with partial placement of Palm Oil Fuel Ash (POFA. Twelve POFA self-compacting concretes of various strength grades were designed at varying percentages of 0, 5, 10, 15, 20, 25 and 30%. The concrete with no placement of ash served as control. Conplast SP432MS was used as superplasticiser in the mix. The experiments are carried out by adopting a water-powder ratio of 0.36. Workability of the fresh concrete is determined by using tests such as: slump flow, T50, V-funnel and L-Box tests. The durability of concrete is tested by acid resistance, sulphate attack and saturated water absorption at the age of 14, 28, 56 and 90 days.

    Full Text Available The environmental impact can be minimised by making use of many industrial wastes in a sustainable manner. Recycling and reutilisation of industrial waste and by-products is of paramount importance in cement and concrete industry. In view of rapid infrastructure growth, there is an emerging need for development of cementitious materials or fillers either to replace cement or fine aggregate for stable growth. One of the industrial wastes is secondary aluminium dross. In this paper, an attempt has been made to study the mechanical and durability aspects of concrete incorporated with secondary aluminium dross. Cement has been partially replaced by secondary aluminium dross in different proportions to study the mechanical and durability aspects. Various properties such as compressive strength, split tensile strength, flexural strength, sorptivity, water absorption, rapid chloride penetration have been studied for the usefulness of secondary aluminium dross as construction material. It is observed that up to 15% replacement of cement by secondary aluminium dross, the responses are comparable with the conventional concrete. Studies have also been carried out by adding other supplementary cementitious materials such as fly ash and silica fume in various proportions along with secondary aluminium dross and found the improved mechanical and durability properties. From the overall study, it can be concluded that the concrete incorporated with secondary aluminium dross can be used for making paver blocks, refractory bricks and for normal concrete strength applications.

    Minard, Benoit

    De nos jours, la problématique du bruit généré par les avions est devenue un point de développement important dans le domaine de l'aéronautique. C'est ainsi que de nombreuses études sont faites dans le domaine et une première approche consiste à modéliser de façon numérique ce bruit de manière à réduire de façon conséquente les coûts lors de la conception. C'est dans ce contexte qu'un motoriste a demandé à l'université de Sherbrooke, et plus particulièrement au groupe d'acoustique de l'Université de Sherbrooke (GAUS), de développer un outil de calcul de la propagation des ondes acoustiques dans les nacelles mais aussi pour l'étude des effets d'installation. Cet outil de prédiction leur permet de réaliser des études afin d'optimiser les traitements acoustiques (« liners »), la géométrie de ces nacelles pour des études portant sur l'intérieur de la nacelle et des études de positionnement des moteurs et de design pour les effets d'installation. L'objectif de ce projet de maîtrise était donc de poursuivre le travail réalisé par [gousset, 2011] sur l'utilisation d'une méthode de lancer de rayons pour l'étude des effets d'installation des moteurs d'avion. L'amélioration du code, sa rapidité, sa fiabilité et sa généralité étaient les objectifs principaux. Le code peut être utilisé avec des traitements acoustiques de surfaces («liners») et peut prendre en compte le phénomène de la diffraction par les arêtes et enfin peut être utilisé pour réaliser des études dans des environnements complexes tels que les nacelles d'avion. Le code développé fonctionne en 3D et procéde en 3 étapes : (1) Calcul des faisceaux initiaux (division d'une sphère, demi-sphère, maillage des surfaces de la géométrie) (2) Propagation des faisceaux dans l'environnement d'étude : calcul de toutes les caractéristiques des rayons convergents (amplitude, phase, nombre de réflexions, ...)

    Full Text Available Terapi adjuvan yang biasanya diberikan pada pasien kanker payudara dan kanker kolorektal adalah kemoterapi dan radioterapi. Terapi adjuvan biasanya diberikan setelah terapi primer untuk meningkatkan angka kesembuhan penyakit, mencegah rekurensi, dan membunuh sel-sel kanker yang tersisa ataupun yang telah bermetastasis (terutama mikrometastasis. Terapi adjuvan juga berfungsi sebagai terapi paliatif untuk meningkatkan harapan hidup pasien kanker. Dalam kenyataannya banyak pasien kanker, khususnya kanker payudara dan kolorektal yang menghindari tindakan kemoterapi dan radioterapi. Dari 38 orang pasien kanker payudara dan kolorektal, didapatkan bahwa 26,3% takut gagal, 39,5% takut efek samping, 7,9% biaya yang mahal, 10,5% karena berlangsung dalam jangka waktu yang lama, dan 15,8% tidak takut terhadap kemoterapi dan radioterapi. Hasil penelitian ini menunjukkan bahwa tingkat pemahaman pasien kanker payudara dan kanker kolorektal terhadap tindakan kemoterapi dan radioterapi masih cukup rendah dimana 68,4% sampel tidak tahu dan tidak mengerti tentang tindakan kemoterapi dan radioterapi. Pemahaman yang kurang tentang tindakan kemoterapi dan radioterapi ini nantinya dapat mengakibatkan timbulnya persepsi negatif terhadap tindakan kemoterapi dan radioterapi. Maka dari itu sangat diperlukan adanya suatu edukasi yang baik bagi setiap pasien tentang penyakit dan modalitas terapi yang akan diberikan. Dokter diharapkan mampu untuk mengubah persepsi negatif pasien terkait tindakan kemoterapi dan radioterapi.  

  20. Polylactic Acid-Based Polymer Blends for Durable Applications

    Finniss, Adam

    There has been considerable scientific interest in both research and commercial communities as of late in the area of biologically based or sourced plastics. As the consumption of petroleum rises and concerns about climate change increase, this field is likely to grow even larger. One bioplastic that has received a great deal of attention is polylactic acid (PLA). In the past, this material was used mainly in medical or specialty applications, but advancements in manufacturing have led to a desire to use PLA more widely, especially in durable applications. Unfortunately, PLA has several drawbacks that hinder more widespread usage of the material as a durable item: it has low ductility and impact strength in bulk applications, along with poor stability in the face of heat, humidity or liquid media. To combat these deficiencies, a number of techniques were investigated. Samples were annealed to create crystalline domains that would improve mechanical properties and reduce diffusion, blended with graphene to create barriers to diffusion throughout the material, or compounded with a polycarbonate (PC) polymer phase to protect the PLA phase and to enhance the mechanical properties of the blend. If a material containing biologically sourced components with good mechanical properties can be created, it would be desirable for durable uses such as electronics components or as an automotive grade resin. Crystallization experiments were carried out in a differential scanning calorimeter to determine the effects of heat treatment and additives on the rather slow crystallization kinetics of PLA polymer. It was determined that the blending in of the PC phase did not significantly alter the kinetics or mechanism of crystal growth. The addition of graphene to any PC/PLA formulation served as a nucleating agent which speeded up the crystallization kinetics markedly, in some cases by several orders of magnitude. Results obtained from these experiments were internally consistent

  8. The States-of-arts and Key Scientific Issues on Durability Research of Concrete Structures

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    Concrete has traditionally been regarded as a durable material requiring little or no maintenance. However, over the past several decades, a number of durability related problems have emerged and stimulated research into the factors relating to concrete durability globally. The challenge now facing practicing engineers is how to design and build structures that not only satisfy the specified structural requirements, but also achieve the performance levels required from a durability standpoint. Research works on concrete structural durability have been widely reported in the literature over the last several decades. In this paper, reviews of four stages of research work on durability, i e, environments, materials, components, and structures, were presented. Afterwards, the key scientific issues in this field were also pointed out.

    Full Text Available In 2008 the first Egyptian booklet Machine Readable Passport/ MRP has been issued and its security and informative standard quality levels were proved in a research published in 2011. Here the durability profiles of the Egyptian MRP have been evaluated. Seven mechanical durability tests were applied on the Egyptian MRP. Such tests are specified in the International Civil Aviation Organization / ICAO standard requirements documents. These seven very severe durability tests resulted in that the Egyptian MRP has achieved better & higher results than the values detected in ICAO-Doc N0232: Durability of Machine Readable Passports - Version: 3.2. Hence, this research had proved the complete conformance between the Egyptian MRP mechanical durability profiles to the international requirements. The Egyptian booklet MRP doesn’t need any obligatory modification concerning its mechanical durability profiles.

  10. Therma1 Conductivity and Durability of Advanced Thermal Barrier Coatings

    Thermal barrier coatings (TBCs) will play a crucial role in advanced gas turbine engines because of their ability to further increase engine operating temperature and reduce cooling, thus helping to achieve engine emission and efficiency goals. Future TBCs must be designed with increased phase stability, lower thermal conductivity, and improved sintering and thermal stress resistance in order to effectively protect engine hot-section components. Advanced low conductivity TBCs are being developed at NASA by incorporating multi-component oxide dopants into zirconia-yttria or hafnia-yttria to promote the formation of thermodynamically stable defect clusters within the coating structures. This presentation will primarily focus on thermal conductivity and durability of the novel defect cluster thermal barrier coatings for turbine airfoil and combustor applications, determined by a unique CO2 laser heat-flux approach. The laser heat-flux testing approach emphasizes the real-time monitoring and assessment of the coating thermal conductivity under simulated engine temperature and thermal gradient conditions. The conductivity increase due to coating sintering (and/or phase change) and the conductivity decrease due to coating delamination have been determined under steady-state, cyclic, uniform or non-uniform heat-flux conditions. The coating radiation flux resistance has been evaluated by varying coating thermal gradients, and also by using a laser-heated radiative-flux source. Advanced multi-component TBC systems have been shown to have significantly reduced thermal conductivity and improved high temperature stability due to the nano-sized, low mobility defect clusters associated with the paired rare earth dopant additions. The effect of oxide defect cluster dopants on coating thermal conductivity, thermal stability and furnace cyclic durability will also be discussed. The current low conductivity TBC systems have demonstrated long-term cyclic durability at very high

    Antireflection (AR) coatings can be incorporated into highly transmitting glazings that, depending upon their cost, performance, and durability of optical properties, can be economically viable in solar collectors, agricultural greenhouses, and PV systems. A number of AR-coated glazings have been prepared under the auspices of the International Energy Agency Working Group on Durability of Materials for Solar Thermal Collectors. The AR coatings are of two types, including (1) various sol-gels applied to glass and (2) an embossed treatment of sheet acrylic. Typically, for unweathered glazings, a 4 - 5% increase in solar-weighted transmittance has been achieved. For AR-coated glass, reflectance values as low as 0.5% - 0.7% at selected wavelengths (680 - 720 nm) were obtained. To determine the durability of the hemispherical transmittance, several collaborating countries are testing these materials both outdoors and in accelerated weathering chambers. All materials exposed outdoors are affixed to mini-collector boxes to simulate flat-plate collector conditions. Results for candidate AR coatings weathered at geographically disperse outdoor test sites exhibit changes in spectral transmittance primarily in the high visible range (600 - 700 nm). Accelerated testing at measured levels of simulated solar irradiance, and at different constant levels of temperature and relative humidity have been performed in different countries. Parallel testing with different levels of laboratory-controlled relevant stress factors permits the time-dependent performance of these materials to be compared with measured results from in-service outdoor exposure conditions. Coating adhesion and performance loss resulting from dirt and dust retention are also discussed.
