  1. Le risque alimentaire face au consommateur

    OpenAIRE

    Didier Torny

    2005-01-01

    Dans le contexte contemporain de multiplication des crises sanitaires, de nombreux travaux en sciences économiques et sociales ont cherché à décrire et analyser le comportement des consommateurs face au risque alimentaire. Ces travaux partagent globalement deux prémisses : ils considèrent l'acte de consommation comme un comportement individuel et attribuent aux consommateurs des "perceptions du risque" qui orientent leurs choix. Une critique de ces deux axiomes amène à soulever la question de...

  2. Aliments purs, aliments sain(ts, la dimension identitaire des peurs alimentaires au Danemark

    Directory of Open Access Journals (Sweden)

    Anne-Elène Delavigne

    2001-04-01

    Full Text Available Le rapport aux aliments et à l’alimentation est marqué au Danemark par la recherche de produits purs, c’est-à-dire sûrs et bons pour la santé et par une politique de la santé publique présente au quotidien. Les débats médiatiques sur les peurs alimentaires font une grande place aux réflexes identitaires « défensifs », dimension confortée par la prise en compte du changement d’échelle décisionnelle au sein de l’Europe et la conscience du jeu d’harmonisation législatif nécessaire dans ce cadre.

  3. Sensibilité du consommateur au gaspillage alimentaire : conceptualisation, antécédents et conséquences

    OpenAIRE

    LE BORGNE, Guillaume

    2015-01-01

    Le gaspillage alimentaire occupe une place croissante dans l'actualité et l'agenda politique. Les travaux en marketing sur le gaspillage en foyer restent relativement peu nombreux, et n'appréhendent pas la façon dont le consommateur est sensible à la question du gaspillage. Nous proposons dans cette thèse une définition de la sensibilité du consommateur au gaspillage alimentaire, et validons une échelle de mesure de ce construit. Puis nous testons un modèle décrivant les relations entre la se...

  4. Accroissement des exportations agricoles et sécurité alimentaire au Viêt-nam

    OpenAIRE

    Lebailly, Philippe; Burny, Philippe

    1995-01-01

    La rénovation des politiques et des méthodes d'action à l'égard de l'agriculture a permis au Viêt-nam de conforter sa position de troisième exportateur mondial de riz. Néanmoins la situation semble moins favorable qu'il n'y paraît. Le marché international du riz est caractérisé par des prix bas et par une forte concurrence entre pays exportateurs. En outre, le marché est réduit et instable. Il s'ensuit que le Viêt-nam, proche de l'autosuffisance, peut tantôt être importateur tantôt exportateu...

    Perrot, Nathalie; Gonne, Sobda; Mathieu, Bertrand

    2013-01-01

    Ces dernières décennies, le sorgho repiqué de contre saison (muskuwaari) n’a cessé de prendre de l’importance dans l’Extrême-Nord du Cameroun et s’est affirmé comme une culture vivrière de base au même titre que le sorgho pluvial. Cette extension s’est accompagnée d’une amélioration du système de culture par les cultivateurs, grâce notamment à la sélection et l’adoption de nouveaux types de sorghos adaptés à diverses contraintes environnementales.

    François Joseph Cabral

    2008-01-01

    L’objet de cet article est de vérifier si les facteurs d’insécurité alimentaire qui exercent une influence clé en milieu urbain ont un impact tout aussi significatif en milieu rural au Sénégal. A cette fin, un modèle logit binomial appliqué aux données de l’enquête ménage du Sénégal (Esam I) est utilisé afin d’identifier les déterminants qui influencent le plus la probabilité d’insécurité alimentaire dans ces zones. Les résultats de l’analyse montrent que tous les déterminants clés de l’inséc...

    1994-01-01

    La présente étude porte sur la structure trophique des communautés de poissons subsistant dans quelques mares résiduelles du Baoulé (haut bassin du Sénégal) au Mali. Il est d'abord montré que les espèces limnivores et phytophages possèdent un intestin significativement plus long que les espèces des autres catégories trophiques, notamment les carnivores et les omnivores. Ce sont ces dernières espèces qui, d'un strict point de vue alimentaire, devraient s'adapter le mieux puisque peu spécialisé...

  11. L’émergence du maïs dans la consommation alimentaire des ménages urbains au Nord-Cameroun

    OpenAIRE

    Nzossié, Éric Joël Fofiri; Ndamè, Joseph-Pierre; Temple, Ludovic; Dury, Sandrine,; Ndjouenkeu, Robert; Kamdem, Michel Simeu

    2012-01-01

    Le système alimentaire du Nord-Cameroun est basé sur les céréales principalement mil et sorgho. Pourtant, l’accroissement de la population urbaine se traduit par une croissance de la production de maïs. Pour l’expliciter nous analysons les dynamiques alimentaires des populations urbaines par deux enquêtes réalisées en août 2007 et janvier 2008 sur 550 ménages. Les résultats soulignent que l’augmentation de la consommation du maïs est importante en période de soudure. Deux explications sont so...

  12. Crise et sécurité alimentaires : vers un nouvel ordre alimentaire mondial ?

    Directory of Open Access Journals (Sweden)

    Christophe Golay

    2012-04-01

    Full Text Available En 2007 et 2008 a éclaté la plus importante crise alimentaire depuis 1974. La hausse du prix des denrées alimentaires sur le marché international, en particulier du blé, du riz, du soja et du maïs, a entraîné une augmentation sans précédent du nombre de personnes sous-alimentées. Malgré une diminution relative du prix des denrées alimentaires depuis l’été 2008, le nombre de personnes sous-alimentées a continué à augmenter en 2009. Cette crise alimentaire a remis la lutte contre la faim au cœur des préoccupations internationales. Depuis le mois de mars 2008, les Etats, les agences des Nations unies et une grande partie des mouvements sociaux ont pris position sur les causes de la crise et les moyens d’y remédier. Malheureusement, alors que ces acteurs tentent de coordonner leurs activités et de proposer des solutions nouvelles, ce sont souvent des recettes anciennes, visant à augmenter la production alimentaire, qui sont mises en avant. Les propositions faites sont souvent contradictoires et les réflexions sur les causes profondes de la faim et de la crise alimentaire – les exclusions sociales, économiques et politiques et les discriminations – ne semblent pas avoir été entendues. Le premier Objectif du Millénaire pour le développement, qui vise à réduire de moitié la proportion des personnes souffrant de sous-alimentation et vivant dans l’extrême pauvreté d’ici 2015, est devenu clairement inatteignable. Mais la crise alimentaire pourrait être à l’origine de la création d’un nouvel ordre alimentaire mondial, basé sur les trois piliers que sont l’aide alimentaire, la sécurité alimentaire et le droit à l’alimentation.

  13. La titrisation aux États-Unis et au Canada

    OpenAIRE

    Christian Calmès; Raymond Théoret; François-Éric Racicot

    2014-01-01

    Since the subprime crisis, securitization by financial institutions has been threatened, both in the U.S. and in Canada. In the U.S., private financial institutions have almost completely stopped their securitization activities. In Canada, the asset-backet commercial paper market is moribund and the new accounting rules (IFRS) hamper the future of residential mortgage securitization. Nevertheless, in spite of obvious weaknesses, securitization contributes to decrease the procyclicality of cre...

  14. HISTORIOGRAPHIES ET FÉDÉRALISME AU CANADA

    Directory of Open Access Journals (Sweden)

    Xavier Dionne

    2009-10-01

    Full Text Available This article studies the historical representation of the two main national communities in Canada; that is, the English-Canadian and the French-Canadian.Throughout the history of the English Canadian community, one cansee an ambitious national project. The national construction of Canada suggests the existence of a neutral model of government but, when looking at this carefully, it is possible to see something quite different. English-speaking historians from Canada have normally introduced the concept of a unitary federalism as the most perfect form of the Canadian integration project. This integrating federalism, that does not lead to emancipation, stems from thecentralist views of John Macdonald, one of the fathers of Canadian federalism. This approach has been kept for over 140 years of common history and, to this date, continues to be one of the main obstacles for minority nations within Canada. To strengthen their thesis, the authors base their work on an extensive analysis exploring the three big strategies used by the central government to assert its authority on the member States of the Canadian Federation in the long term: using the judicial power, centralizing powers andglobalization. The strategies used have varied depending on the economic scenario, political leaders and the political power relations regarding the links between the Federation and the provinces.

    Cet article défend la thèse selon laquelle le tournant conservateur de Harper doit être compris moins en termes hayékiens que comme un désir de redéfinir la « philosophie publique » du Canada dans le sens du toryisme canadien. Les conservateurs chercheraient à repenser ce qu’on appelle communément les « valeurs canadiennes » et l’identité canadienne, que les Libéraux ont pu façonner à leur guise au cours d’un demi-siècle, et de réorienter l’identité nationale vers des principes conservateurs ...

    International Nuclear Information System (INIS)

    Canada ranks ninth in the world in anthropogenic carbon dioxide emissions. Canada currently releases 1.9 percent of global carbon dioxide emissions from combustion of fossil fuels, production and treatment of oil and natural gas, and cement manufacturing. Canadian carbon dioxide emissions doubled between 1956 and 1986, growing at an average rate of about 2.4 percent per year. They reached a peak in 1979 and have since fluctuated within 10 percent of that amount. Despite the significant increase in emissions, Canada's share of global carbon dioxide emissions has declined slightly since 1956. On a per capita basis, Canada ranks fourth among nations in carbon dioxide emissions, with about 4.1 tons in 1986. This rate compares with the U.S. average of 5 tons per capita emissions have grown by about 25 percent since 1956. Canada, though a relatively small source of greenhouse gases, has been deeply involved in finding ways to reduce the risk of climatic change. The nation fortunately possesses opportunities to reduce this risk by saving energy, developing nonfossil energy resources, and facilitating international cooperation for capturing these opportunities worldwide

    International Nuclear Information System (INIS)

    Nuclear research and development in Canada started in the 1940s as a responsibility of the federal government. An engineering design team was established at Chalk River, Ontario, to carry out research on heavy water moderated lattices. A zero-energy heavy water moderated research reactor, ZEEP, was built and achieved criticality in September 1945; it was in fact the first human-made operating reactor outside the USA. In 1947, the 20 MW heavy water moderated national research experimental reactor (NRX) started up. It served as one of the most valuable research reactors in the world, and provided the basis for Canada's development of the very successful CANDU series of pressurised heavy water reactors (PHWR) for power generation. Atomic Energy of Canada Limited (AECL) was established in 1952 as a federal Crown Corporation. It has both a public and a commercial mandate. AECL has overall responsibility for Canada's nuclear research and development programme (its public mandate) as well as for the Canadian reactor design (CANDU), engineering and marketing programme (its commercial mandate). Nuclear energy in Canada is a $5 billion per-year industry, representing about 150 firms, 21 000 direct jobs and 10 000 indirect jobs, and ∼$1.2 billion in exports - the value to the country's economy is much higher than the research and development funding provided by the federal government. The CANDU nuclear reactor system was developed by AECL in close collaboration with the Canadian nuclear industry, and in particular with Ontario Hydro (now Ontario Power Generation). Currently, Canada operates 17 CANDU reactors, which contribute 16% of the country's current electricity consumption. There are also 12 CANDU reactors operating abroad (in Argentina, China, India, the Republic of Korea, Pakistan and Romania). AECL is now developing the 'third generation plus' Advanced CANDU Reactor (ACR-1000), and also has the leading role internationally in developing the Generation IV

    International Nuclear Information System (INIS)

    This paper reports that the Canadian oil and natural gas sector is in for another grim year in 1992. Further streamlining to enhance operating efficiencies and control costs is the first order of the day. About $4 billion worth of producing properties remains on the market, as corporate focus continues to shift to core properties. New management structures put in place in the last two years will be severely tested to improve the sector's financial performance. Massive write-downs in 1990 and 1991 have put balance sheets in much better shape for improved financial performance in the future. Although new long-term debt exceeded redemptions in 1991, largely because of debt- financing of major capital projects, individually most companies are in better shape through significant debt repayment or restructuring. The substantial reductions in interest rates will also help to enhance discretionary cash flow. At this stage, everything appears to be in place to expect that 1992 will represent the bottom of the down-cycle for Canada

  13. Cholestérol alimentaire et morbi/mortalité cardiovasculaire

    Directory of Open Access Journals (Sweden)

    Hansel Boris

    2015-03-01

    Full Text Available Si l’hypercholestérolémie est un facteur de risque avéré des maladies cardiovasculaires, le rôle du cholestérol alimentaire dans la survenue de ces maladies reste discuté. À l’origine, les travaux d’Anitshkow chez le lapin ont montré qu’une alimentation riche en cholestérol se traduit par le développement de plaques d’athérome. Les études d’intervention chez l’homme ont examiné l’effet du cholestérol alimentaire et/ou des œufs sur les lipides plasmatiques, aboutissant à des résultats contradictoires. Elles ont également fait émerger la notion complexe d’hypo- et d’hyper-répondeur au cholestérol. L’épidémiologie observationnelle ne permet pas non plus de conclure à un effet délétère du cholestérol alimentaire chez l’homme. Néanmoins, chez les sujets diabétiques, une association positive entre la consommation et l’incidence des événements cardiovasculaires est retrouvée assez constamment, sans que l’on puisse l’expliquer de manière convaincante. Il n’existe pas d’essai clinique examinant l’impact des aliments riches en cholestérol sur la survenue des événements cardiovasculaires. Toutefois, les résultats des études MRFIT et PREDIMED ne vont pas dans le sens d’un effet délétère du cholestérol alimentaire. À l’inverse, les travaux réalisés sur le transporteur intestinal du cholestérol NPC1L1 sont en faveur de l’intérêt d’inhiber l’absorption du cholestérol pour réduire l’incidence des maladies cardiovasculaires. L’ensemble des données disponibles n’est pas en faveur d’un rôle clé du cholestérol alimentaire dans la survenue des maladies cardiovasculaires. Elles ne permettent donc pas d’en faire une cible prioritaire du régime à proposer pour prévenir les maladies cardiovasculaires.

    Full Text Available La politique nationale de l’eau (PNE du Québec a été présentée en 2002 par le gouvernement Landry (Parti québécois. Des expériences prometteuses tentées quelques années auparavant ont en effet conduit le ministère de l’environnement à développer des instruments de planification à l’échelle des bassins versants et à encourager la gouvernance locale de l’eau. Il s’avère cependant aujourd’hui que les moyens alloués à la PNE sont insuffisants au regard des objectifs initialement affichés par les pouvoirs publics. En particulier, les organisations de bassins versants demeurent en partie inopérantes faute d’argent. La mise en place de redevances pénalisantes visant les pollueurs, les consommateurs et les aménageurs s’impose désormais pour alimenter de manière beaucoup plus importante le Fonds national de l’eau du Québec, destiné à financer la PNE.The Québec National Water Policy (PNE was first introduced in 2002 by the Landry government (Parti québécois. Promising experiments conducted a few years before had led the ministry of the Environment to encourage the development of policy planning instruments within watersheds, and to foster local water governance. However, it now seems that the means allocated by the provincial government to achieve theses goals are inadequate considering the scope of the PNE. In particular, local water basin agencies remain ineffective because of a lack of funding. The implementation of taxes aimed at polluters, consumers and operators seems unavoidable so as to finance the Quebec National Water Fund, set up originally to finance the PNE.

Nous nous demandons dans quelle mesure les territorialités amérindiennes permettent le maintien d’une certaine diversité alimentaire. Nous couplons pour cela l’étude des systèmes de production, l’observation participative des pratiques alimentaires et l’analyse des principales filières d’approvisionnement. L’incorporation de produits alimentaires d’origine exogène dans les repas des amérindiens est due principalement aux conditions d’accès aux ressources naturelles et de mobilisation de la main d’œuvre. Pour contourner ces contraintes, les groupes domestiques articulent les ressources urbaines et forestières grâce à des mobilités circulaires. De plus, à l’échelle de la famille élargie, les réseaux d’échange entre ville et forêt favorisent le maintien de la qualité des produits et l’agrobiodiversité.Food Diversity And Urbanization, Agrarian Transformations And Food Recomposition In The North-Western Amazon (Brazil São Gabriel da Cachoeira, a town located in the northwest of the Brazilian Amazon, is mainly inhabited by indigenous families. Our question is whether indigenous territorial practices lead to conservation of food diversity. Data were obtained by agro-economic interviews, participative observation of food practices and analysis of the main food chain supply in the town. Consumption of agroindustrial food by indigenous families is mainly due to urban conditions of access to natural resource and labor force employment. To cope with these constraints, domestic groups use multi-sited production units and circular mobility across urban and forest areas. Moreover, at a larger scale, the exchange networks between city and forest help to maintain the quality of products and agrobiodiversity conservation.

    The local consequences of fresh fall-out, especially in the case of atmospheric nuclear explosions, are reviewed from the point of view of the internal contamination of the consumer of foodstuffs of animal origin. The edibility of foodstuffs derived from animals having grazed in the presence of fall-out is evaluated both from the wholesome and radio-toxicological points of view. The contamination level of these foodstuffs is calculated as a function of the ground fall-out, and of agronomical and ecological parameters for each radio-nuclide of the animal food chain. The internal exposure of the human consumer is calculated from this level as a function of the diet and of various parameters especially temporal. The equivalent dose to each critical organ, including the digestive tract is deduced from the burdens of each organ. From this a nutritional hygiene in the areas affected by fall-out is obtained, in relationship to the action levels fixed by the responsible authorities in exceptional circumstances. Criteria for these action levels are given as function of the food rations.

La comestibilite des aliments provenant de betes de boucherie ayant pature sous les retombees est evaluee au double point de vue de la salubrite et de la radiotoxicologie. Le niveau de contamination de ces denrees est calcule en fonction de la retombee au sol, des parametres agronomiques et ecologiques pour chaque radioelement de la chaine alimentaire animale. La contamination interne du consommateur humain est calculee a partir de ce niveau en fonction des modalites d'ingestion et de divers parametres, notamment temporels.

    Cet article porte sur la notion d’« authenticité » appliquée au patrimoine des « vins de terroir ». Ces dix dernières années, des vignerons accusent la législation des AOC (Appellations d’Origine Contrôlées) de ne plus protéger les terroirs et de laisser les mauvaises pratiques des vignerons les pervertir.

    Full Text Available La sensibilisation de l’organisme par des allergènes d’origine alimentaire s’exprime par l’apparition d’immunoglobulines spécifiques (IgE. Ces allergies sont provoquée dans la quasi totalité des cas par des protéines. De nombreux aliments sont susceptibles de provoquer des allergies chez certains sujets sensibles. On trouve ainsi des allergies aux Drupacée (approximativement 16% de la fréquences des allergies alimentaires, aux Ombellifères (11%, à l’œuf (8%, aux Légumineuses (3%, aux crustacés (8%, au poisson (7%, à l’avocat et au kiwi (5%, au lait (5%, à la farine de blé (4%, à la banane (3%. Parmi les allergies alimentaires, l’allergie à l’arachide est particulièrement fréquente. Dans le cas des réactions croisées, l’organisme est sensibilisé par un premier contact avec un allergène distinct de celui qui va induire les réactions immunitaires excessives et aberrantes. Afin d’évaluer le potentiel allergénique de protéines alimentaires il est nécessaire de disposer de tests permettant de contrôler les matières premières et d’évaluer les moyens technologiques permettant de réduire l’allergénicité de certains produits. Des modèles d’allergie à l’arachide par sensibilisation orale, nasale ou intrapéritonéale sont développés chez la souris. Les données disponibles indiquent qu’il est possible de reproduire certains aspects de la sensibilisation et des réactions croisées observées chez l’homme. Ces modèles de sensibilisation permettent d’évaluer le potentiel allergénique de protéines alimentaires.

    Full Text Available Après des décennies d’augmentation constante de leur criminalité, le Canada et les États-Unis connaissent des baisses importantes depuis le début des années 1990. Plusieurs explications ont récemment fait surface aux États-Unis sur les facteurs pouvant rendre compte de cette baisse, dont une augmentation du nombre de policiers, l’application par les forces de l’ordre de méthodes plus répressives et l’augmentation importante du taux d’incarcération. Notre analyse des tendances de la criminalité entre 1991 et 2001 pour quatre types d’infractions indique que des baisses comparables de la criminalité sont observables au Canada sans que des changements notables en termes de répression policière ou d’incarcération soient notables. Ainsi, les explications démographiques, économiques et culturelles semblent plus aptes à rendre compte des baisses de la criminalité en Amérique du Nord.After decades of continuously increasing crime rates, Canada and the United States have now experienced their first prolonged period of decline in crime rates. Criminologists are just starting to look at the reasons that may explain such a reversal. In the U.S., many factors have been invoked to explain the trend, including increases in the number of police officers, more aggressive policing, and an increased use of incarceration. Although Canada’s crime trends are similar to those found in the U.S., there has been little or no change in policing practices or incarceration trends. This paper suggests that the causes of the decline in crime rates lie elsewhere, namely, in demographic shifts, improved employment opportunities and changes in collective values. Full Text

    Full Text Available Runar Døving, anthropologue spécialiste des habitudes alimentaires en Norvège, répond dans cet entretien à des questions sur le craquant, le croquant et le croustillant dans la culture de l’alimentation norvégienne. Réponses et questions s’enchainent au fil de l’interview et permettent un certain nombre de réflexions et d’éclaircissements sur le craquant comme caractéristique alimentaire, culinaire et culturelle. Le craquant semble essentiellement reposer sur une structure binaire, souvent dichotomiste, opposant le craquant au mou, le croquant au doux et par la même le masculin au féminin, voire le croustillant moderne et décadent des chips à la sécurisante douceur culturelle des pommes de terres à l’eau.Runar Døving is an anthropologist who has been working for many years on food habits in Norway. In this paper he answers questions about the value that crunchy and crispy food may have in Norwegian food culture. The text links questions and answers together in a way that presents thoughts and perspectives about the culinary and cultural aspects of the crunchy and the crispy. The crunchy seems to be built on a dual structure based on the many oppositions between the crunchy and the soft, the crispy and the mushy, which actually remind one of masculine and feminine, and even the modern decadent aspects of potato crisps that contrasts with the secure smoothness of boiled potatoes.

    Full Text Available Dans de nombreux pays, les élèves et les étudiants ont augmenté le temps consacré au travail rémunéré durant leurs études. Ils ne travaillent plus uniquement l’été, au moment des vacances, mais aussi pendant l’année scolaire. Les recher­ches portant sur l’effet du travail salarié sur les parcours scolaires tendent à montrer qu’il existe une relation convexe entre l’intensité du travail salarié et les départs sans diplôme du système scolaire : les taux d’abandon semblent plus élevés pour les étudiants qui ne travaillent pas et pour ceux qui travaillent plus de 25 heures. Cependant, le caractère transversal des données utilisées fait qu’elles ne permettent pas de saisir l’effet causal de la variation du temps de travail sur la poursuite des études. Dans cet article, nous utilisons une méthodologie quantitative longitudinale pour examiner les effets de l’intensité du travail rémunéré sur la persévérance dans le premier programme universitaire suivi au Canada. Les résultats montrent qu’il y a bien une relation causale entre le fait de travailler plus de 25 heures et l’abandon, mais qu’elle est seulement observée pour les hommes, et que cet effet n’est significatif qu’au début du program­me. Par ailleurs, l’association avec le fait de ne pas travailler semble s’inter­préter davantage comme un effet de sélection.In many countries, pupils and students have increased the time devoted to remunerated work during their studies. They no longer work just in summer, during vacations, but also during the school year. Research relating to the effect of salaried work on the school courses tends to show that there exists a convex relationship between the intensity of the salaried work and the departures without diplomas from the school system: the rates of abandonment seem higher for students who do not work and for those who do not work or work over 25 hours weekly.

    Full Text Available L’étude anthropologique des pratiques alimentaires de migrants boliviens de retour ayant longuement séjourné en Argentine permet d’aborder la problématique de la migration et de l’identité : la construction sociale, réelle et imaginaire, de la migration ne passe-t-elle pas aussi par l’alimentation ? Ce que l’on mange ici et là-bas éclaire, en creux, le succès ou l’échec donné à la migration par les migrants et aide à comprendre plus finement les significations locales données à la pauvreté et à la richesse, au bien-être et au mal-être. L’observation et les « récits de vie alimentaires » menés dans une perspective intergénérationnelle – sur l’importance de la consommation attribuée au pain, à la viande et au soda– conduisent finalement à s’interroger sur la situation sociale et symbolique des migrants de retour dans leur société d’origine comme dans la société d’accueil. Au-delà, l’étude montre que les pratiques et les représentations alimentaires reflètent et structurent à la fois des relations sociales, des relations de sexe et des rapports au corps, et qu’elles permettent d’induire des processus de construction d’identités complexes.The anthropological study of Bolivian returnees’ food practices, who have spent a long time in Argentina, leads us to deal with the problematic of migration and identity: as a matter of fact, the social construction of migration, either real or imaginary, is also based on alimentation. What is eaten here and there enlightens, in a way, the success or failure of their migration, as perceived from the migrants’ point of view; it helps to deeply understand the local significations given to poverty and wealth, to well-being and discontent. Observation and « intergenerational food life stories », conducted on the importance of consumption of bread, meat and sodas, finally lead to question the social and symbolic situation of returnees

Ces situations sont riches d’ambivalences : attachement aux habitudes mais aussi passage du dégoût au goût ou bien de la méfiance à la curiosité, double appréciation pour la nourriture dont la présentation n’est pas estimée de la même façon que les produits eux-mêmes, efforts pour accepter les manières de table dans le cadre d’un rapport de force social et/ou affectif, enfin ‘‘oubli’’ de la question alimentaire au profit du lien social qu’il produit.From an investigation made in urban zones with nine male and female French people having migrated to Taiwan and married with Taiwaneses, the author studies the issue of food tensions in situation of mixed couples. He presents the hypothesis that these tensions vary according to food grips: breakfast, lunch, street foods, conjugal dinner, meals with allies. Such food tensions provoke varied practices and judgments: attachment to habits but also the passage of disgust to appreciation, distrust regarding curiosity, double appreciation for food displayed which is not esteemed in the same way as the products themselves, efforts to accept table manners within the framework of a social or emotional balance of power, finally ‘‘forgetting’’ the issue for the benefit of the social link which it produces.

    Full Text Available Au tournant du XXIe siècle, les télédiffuseurs canadiens ont programmé plus de documentaires. Les points communs entre l’information et certains documentaires ont aidé à leur rapprochement en télévision. Ce changement s’est produit sur un fond règlementaire où l’encadrement étatique canadien initialement distinct entre les activités cinématographiques et télévisuelles est devenu interdépendant en raison de plusieurs changements politiques et économiques. Depuis 1968, le Conseil de la radiodiffusion et des télécommunications canadiennes (CRTC est responsable, entre autres, de la législation, de la mise en application des règlements et de la surveillance de toutes les parties impliquées en radiodiffusion. Parmi les activités organisées par le CRTC, il y a la tenue de consultations publiques où les intervenants du secteur de la radiodiffusion et le public peuvent commenter, à l’écrit et en audience publique, les différents enjeux de la radiodiffusion. Ce texte analyse une consultation publique organisée en 1999 dans laquelle le CRTC proposait une définition du documentaire à titre d’émission canadienne prioritaire et de catégorie générale d’émissions. Dans cette analyse préliminaire, nous nous attardons sur les commentaires des intervenants sur cette proposition de définition, leur résonance avec le journalisme et leur influence sur l’amendement de la définition. Enfin, nous considérons les répercussions possibles de cette nouvelle définition sur l’intégration des documentaires dans la programmation et plus particulièrement, dans la filière information, chasse gardée du journalisme télévisuel.At the turn of the twenty-first century, Canadian broadcasters programmed more documentaries. Common elements between the news and some documentaries helped bridge them in television.

    Full Text Available L’article examine le militantisme LGBT et les résultats des politiques en matière de droit pénal et du mariage entre personnes de même sexe de 1969 à aujourd’hui, dans le cadre d’une analyse comparée du fédéralisme aux États-Unis et au Canada. Nous soutiendrons que le fédéralisme a grandement façonné les politiques publiques relatives aux droits des LGBT. Dans le régime américain, le potentiel d’expansion du fédéralisme a favorisé les changements graduels de politiques dans les États et, parallèlement, les multiples points de véto créés par le système de séparation des pouvoirs conjugués aux compétences conférés aux États dans d’importants domaines de politiques ont entravé ces changements de politiques. Dans le régime canadien, la centralisation des mécanismes de protection des droits de la personne dans la Charte de même que la dynamique descendante de l’exercice du pouvoir dans le régime parlementaire de type Westminster ont facilité les changements de politiques. Le fédéralisme est souvent perçu comme un obstacle à l’adoption de politiques progressistes. La répartition des pouvoirs entrave l’élaboration de politiques cohérentes et prête le flanc à la prolifération de vétos dont peuvent se prévaloir des groupes influents pour freiner le changement. Les critiques de cette perspective arguent depuis longtemps que, même si le fédéralisme multiplie les points de véto, il présente aussi de nombreuses possibilités d’innovation. Ils font valoir que les groupes ont plus de poids dans les régimes fédéraux puisqu’ils peuvent exercer leur influence à deux paliers de gouvernement plutôt qu’à un. Ainsi, un groupe qui ne réussit pas à se faire entendre à l’un des paliers pourra tenter sa chance au second et pourra même dresser un palier contre l’autre pour atteindre ses objectifs stratégiques.

    Full Text Available Les nouvelles technologies de manipulation génétique ont été présentées par certaines entreprises comme une opportunité pour l’humanité d’en finir avec la malnutrition, grâce au développement de la production agricole que cela pouvait entraîner. Le débat qui s’en est suivi n’est pas le fruit de résistances archaïques de nos sociétés au « progrès » mais offre une nouvelle fois l’occasion de rappeler des réalités incontournables sur la politique agricole. Premièrement, la priorité encore aujourd’hui reste pour chaque pays d’assurer à la population une sécurité alimentaire aussi bien sur le plan quantitatif que qualitatif sans attendre son salut des importations en provenance des pays les plus compétitifs. Deuxièmement, les agriculteurs ne peuvent utiliser les techniques disponibles que dans un contexte économique et politique favorable. Troisièmement, le patrimoine génétique de l’humanité était jusqu’à maintenant un bien collectif. Il serait dangereux qu’il soit désormais privatisé.

    Depuis les années 1960, plusieurs pays d’Asie du Sud-Est ont réussi à atteindre, surtout grâce à l’augmentation de la production agricole, une plus grande sécurité alimentaire. L’État postcolonial a été au cœur de l’essor de l’agriculture en Indonésie et en Malaisie, mais son rôle tend à se modifier surtout depuis le tournant du millénaire. Pour cerner les transformations des politiques agricoles contemporaines en Indonésie et en Malaisie, nous abordons la question suivante : quelles sont les...

  15. La Chine au risque de la dépendance alimentaire

    Chaumet Jean-Marc

    2012-09-01

    Full Text Available China’s opening to the world and economic reforms began in 1978 and resulted in remarkable economic growth. Food transition then occurred for part of Chinese citizens, meaning more meat consumption and less grain consumption. Many factors explained this transition. As China’s economy grew rapidly, peoples’ average income have been rising and cities have been growing at a rapid pace. Foreign investments in retail also have played a major role. But some gaps remain throughout the country: income inequality between rural and urban, between people living on the coast and in-land people, among generations. . . Food transition is not over yet for an important part of the Chinese population. China was able to feed its population until the beginning of the 21st century. But the imports of soybean and milk products have widened its food trade deficit since 2004. The crisis that has been affecting the global economy for the past 4 years might force the Chinese authorities to boost home consumption to be able to maintain the economic growth. This move would mean more imports and might have big consequences on food international trade in the years to come.

    Directory of Open Access Journals (Sweden)

    Cuvelier Marie-Elisabeth

    2012-03-01

    Full Text Available Vegetable oils are chemically unstable due to the sensitivity to oxidation of their unsaturated fatty acids. The oxidative mechanisms are based on complex and radical reactions that always result in a significant loss of oil quality in both sensorial (rancidity and nutritional values (loss of polyunsaturated fatty acids and vitamin E. Monitoring the oxidation state of oil can be performed using different markers, each bringing a partial information of the whole phenomenon, but unable to predict by itself the future stability of the oil. The accelerated ageing tests used in reasonable heating conditions are useful for measuring the resistance of oil to oxidation but are difficult to extrapolate to normal storage conditions. The oxidative degradation of oil during storage can be delayed by protecting it from light, heat, oxygen and metals. Another way consists to increase the retention of endogenous antioxidants naturally contained in the oil seeds, such as tocopherols (vitamin E, which are partially removed during conventional operations of extraction and refining.

    Full Text Available Ireland and Canada face the common challenge of having to protect their cultural production which is a cornerstone of their national identity from American attempts at breaking down any barrier preventing the free circulation of goods and services, including culture. Canada—and especially Québec—has developed a tradition of loud and vocal opposition to what is perceived as American cultural imperialism. On the other hand, Ireland is less critical of the occupation of its audiovisual space by American productions on the strength of its historical ties with the United States. In Ireland, broadcasting comes under the control auspices of a government department which is not otherwise related to cultural issues. The ruling party Fianna Fáil has adopted a purely liberal approach to its national broadcaster, whereas, on the other side of the Atlantic, Canadian official discourse on the matter has grown closer to the European notion of a cultural exception or exemption in favour of culture in order to preserve the core of national identities in the face of globalization.

Ces textes de Qwo-Li Driskill, Candace Brunette, Daniel Heath Justice, Yves Sioui-Durand et Jo-Ann Episkenew, entre autres, nous permettent de saisir de l’intérieur le rôle privilégié assigné au théâtre et aux pratiques de la performance par toute une génération de chercheurs et d’activistes autochtones des trente dernières années. Nous en retenons que deux courants animent cette production théorique et méthodologique axée sur la décolonisation : le refus des esthétiques liées à la posthistoire (postmodernisme et postcolonialisme et le recours à un imaginaire et un lexique empruntés aux études contemporaines du traumatisme individuel et collectif. Indigenous theatre collectives have been active on all fronts in recent years, not only by staging and publishing a large number of plays written by Native writers, but also through the production and circulation of a significant number of theoretical texts on Indigenous theatre methodologies. Writings by Qwo-Li Driskill, Candace Brunette, Daniel Heath Justice, Yves Sioui-Durand and Jo-Ann Episkenew, among others, allow us to understand from within the role assigned to the theatre by a generation of Indigenous activists and scholars.

    2011-05-01

    Full Text Available Food habits and cultures are constantly evolving – changing in response to new innovations that are driven by agribusiness players large and small. As the ‘actors of innovation’ these people reinvent their relationship with tradition. This article is based on a study of three rural areas in the department of the Midi-Pyrenees: Southern Aveyron, Pays du Haut Rouergue (North Aveyron and Pays d’Armagnac in the Gers. It highlights three main profiles of innovators in the field of food heritage, each one corresponding to a form of organization that in turn flows from a particular relationship with the territory and its local players. It also highlights the importance of local perceptions and attitudes towards these innovators, demonstrating the pivotal role of local companies in the appropriation of innovative process.Les cultures alimentaires sont évolutives et font l’objet de différentes formes d’innovation. Qu’ils soient artisans, industriels ou institutionnels, reconnus ou plus marginaux, les différents acteurs de la filière agro-alimentaire portent ces mouvements d’innovation, renouvellant ou inversant ainsi leur rapport à la « tradition ». Cette dernière se trouve alors remaniée dans le projet de valorisation. L’étude fait ressortir trois principaux profils d’innovateurs dans le champ de la patrimonialisation alimentaire. Chacun de ces profils correspond à une forme d’organisation, elle-même inscrite dans un rapport particulier au territoire et au système d’acteurs local. Cette typologie souligne par ailleurs l’importance du regard de la population locale sur ces innovateurs ; elle montre le rôle central des sociétés locales dans l’appropriation des processus d’innovation, participant ou non à leur légitimation. Si le processus d’innovation a longtemps été porté par des groupes d’acteurs structurés, reconnus par la société locale, il est également, le fait de petits groupes ou

Par delà la diversité des habitudes culinaires et de leurs formes (ex : végétarisme, par delà les éventuelles variations individuelles de l’observance religieuse au cours du cycle de vie, l’interdit alimentaire de mêler lait et viande est respecté par l’ensemble des personnes rencontrées. Il s’agit alors d’en comprendre le sens et la portée. Les conséquences matérielles de cet interdit alimentaire permettent de saisir l’importance de la religion dans le logement et les activités de tous les jours. Elles conduisent à articuler le plan matériel et le plan symbolique en suggérant une interprétation anthropologique de cette prohibition, en lien avec les écrits bibliques et les analyses déjà menées sur le sujet.This article is based upon research on Ashkenazi Jewish families living in London. It deals with the way, in Judaïsm, the prohibition of eating meat and dairy foods together is materialised through the use of kitchen utensils on a day to day basis.

Consequences which lead to the linking of material uses and their symbolic significance by suggesting an anthropological interpretation of this dietary law in accordance with Biblical writings.

  17. Geochemistry of the metavolcanic rocks in the vicinity of the MacLellan Au-Ag deposit and an evaluation of the tectonic setting of the Lynn Lake greenstone belt, Canada: Evidence for a Paleoproterozoic-aged rifted continental margin

    Science.gov (United States)

    Glendenning, Michael W. P.; Gagnon, Joel E.; Polat, Ali

    2015-09-01

    The Paleoproterozoic (ca. 1900 Ma) Lynn Lake greenstone belt of northern Manitoba, Canada, has been previously characterized as comprising a series of tectonically juxtaposed intra-oceanic-derived metavolcanic rocks. The results of more recent local and regional studies, however, support a significant contribution of continental crust during formation of the metasedimentary, metavolcanic, and intrusive igneous rocks that comprise the majority of the Lynn Lake greenstone belt. The tectonic model previously proposed for the Lynn Lake greenstone belt, however, did not consider the geodynamics of the Lynn Lake greenstone belt in the context of all available data. In this study, we report the results of outcrop mapping and petrographic analysis, as well as major, minor, and trace element geochemical analyses for 54 samples from the Northern terrane, and integrate and compare the results with data from previously published studies. These data are used to recharacterize the metavolcanic rocks and to develop a new geodynamic model for the formation of the Lynn Lake greenstone belt. Ultramafic to intermediate rocks in the vicinity of the MacLellan Au-Ag deposit are characterized primarily by E-MORB-like trace element characteristics and Th-Nb-La systematics, which are interpreted to be the result of a primary, plume-derived melt interacting with continental lithosphere at a thinned (i.e., rifted) continental margin. Similarly, the majority of the mafic to intermediate rocks that comprise the Lynn Lake greenstone belt are characterized by flat to E-MORB-like trace element patterns and Th-Nb-La systematics, which are consistent with mantle plume-derived, contaminated, oceanic continental rift or rifted margin setting rocks. This study suggests that the metavolcanic rocks of the Lynn Lake greenstone belt were derived via rifting between the Superior and Hearne Cratons, which resulted in the formation and growth of the Manikewan Ocean. Alternatively, the metavolcanic rocks

    pressure communication to geological storage of CO2 in aquifers are briefly discussed. Le but de l’article est de comprendre l’accroissement de pression dans le gisement de Zama X2X, utilisé pour le stockage degaz acide (NO de l’Alberta, Canada, et aussi d’examiner si la baisse de pression, observée ultérieurement,est la conséquence d’une dissipation par un aquifère de grande taille. Le gisement de Zama X2X, d’uneextension de 1 km2 environ, est connecté à quatre autres gisements voisins par l’intermédiaire d’un aquifère commun sous-jacent. L’analyse de la pression à travers tous ces gisements indique un bon niveau decommunication hydraulique. La pression initiale de l’accumulation de Zama X2X était d’environ 15 MPa.Pendant la production d’huile, la pression a commencé par décroître, pour se stabiliser vers 10 MPa audébut de la décennie 1970. Mais ensuite la pression a repris son ascension, jusqu’à atteindre 26 MPa en1986. Un nouvel épisode de baisse est alors intervenu et la pression s’est établie vers 22 MPa en 1995,au moment où l’on a commencé à injecter du gaz acide (80 % CO2 et 20 % H2S – l’opérateur, toutefois,injectait ce gaz à des débits et à des pressions en tête de puits qui se situaient en deçà des seuils autoriséspar l’Administration. En dépit d’une production significative d’eau et d’hydrocarbures, la pression à ZamaX2X est ensuite restée plus élevée que la pression vierge, d’au moins 5 MPa, au point qu’en 1998 les opérations d’injection de gaz furent suspendues. La production d’huile a cependant été maintenue jusqu’en 2002. Des simulations numériques effectuées avec CMG-IMEXTM, assorties d’une analyse de sensibilité,montrent ici que la ré-injection de plus de 1 million de m3 d’eau dans le gisement voisin de Zama YY,entre 1970 et 1988 puis en 1992-93, est la principale cause du comportement de la pression à Zama X2X.Les deux champs sont en effet connect

  6. Perception oro-sensorielle des lipides alimentaires et obésité

    2016-05-01

    Full Text Available La gustation est un système dynamique capable d’une adaptation physiologique rapide en réponse aux changements environnementaux permanents qui caractérisent notre alimentation (rythme, qualité, quantité. Basé sur la modulation des seuils de sensibilité gustative, ce système homéostatique contribue à la construction du comportement alimentaire en orientant les choix de consommation. On peut donc penser qu’un dysfonctionnement de ce système régulateur peut avoir un impact sur les habitudes alimentaires et donc, à terme, sur la santé. La mise en évidence récente chez le rongeur (rat, souris qu’une obésité induite par le régime non seulement entraîne une détérioration de la détection orale des lipides mais se traduit également par une préférence accrue pour le «gras», plaide en faveur de cette thèse. Chez l’homme, nos travaux indiquent que les sujets obèses, dont la détection oro-sensorielle des lipides est défectueuse, surconsomment des aliments riches en graisse. Ces données murines et humaines suscitent une question fondamentale : quel est le lien entre lipides, obésité et désordres gustatifs? Cette mini-revue se propose de faire le point des connaissances actuelles sur ce sujet.

    Full Text Available Cet article s’intéresse aux mécanismes de construction de la légitimité des productions alimentaires locales. Les données présentées sont issues d’une enquête qualitative portant sur les processus de valorisation dans le département de la Drôme. Nous présenterons la construction des normes internes au système d’action de valorisation repéré sur ce territoire à travers trois de ses fondements : l’adhésion à des normes de production, l’adhésion à des normes de distribution ainsi qu’à une inscription dans la vie culturelle locale. À travers ces trois aspects, nous verrons se profiler la logique de valorisation caractérisant ce système. Cette logique de valorisation transmet des valeurs spécifiques aux productions et participe ainsi à les légitimer. La mise en relief de cette forme de légitimité est l’objectif de la réflexion proposée.The aim of this article is to highlight the way in which local food products are given legitimacy, presenting qualitative data from a survey of product enhancement activities in the department of the Drôme. It describes the internal standards defined by three tenets underlying those activities: adherence to production standards; adherence to standards of distribution; and adherence to local cultural life. Our aim is to outline the rationale behind the system - a rationale that in conferring particular values to particular products also helps to give them legitimacy.

    2011-05-01

    Full Text Available Local food products, either new, “traditional”, or based on a specific conception of food heritage, play an important role in the development of the rural tourism sector in Norway. Building on different concrete Norwegian case studies, this article seeks to better understand the role tourism plays in the creation, or revival, of cultural identity based on local food products and food heritage. The paper uses the concept of the “tourist gaze” in order to analyze tourists and local consumers’ perceptions and appropriation of local food. The article highlights the consequences of the emergence of culinary and local food heritage for tourists in Norway, and concludes that tourism increases the awareness of food heritage and strengthens local identity, although these food products are not much used in ordinary food consumption.Les produits locaux, nouveaux, basés sur des recettes « traditionnelles », voire sur une conception particulière du patrimoine alimentaire, jouent un rôle important dans le développement du secteur touristique rural en Norvège. Fondé sur différents cas d’études norvégiens concrets, cet article permet de mieux comprendre le rôle joué par le tourisme dans la création, ou la construction, de l’identité culturelle basée sur le patrimoine alimentaire et le développement récent des produits locaux. Afin d’analyser la perception et l’appropriation des produits localisés par les consommateurs, nous proposons une approche fondée sur la notion de « regard touristique ». Cet article s’achève finalement sur les conséquences de l’émergence du patrimoine alimentaire local dans le tourisme, soulignant à la fois l’influence sur les pratiques alimentaires et sur la mise en valeur d’une identité culturelle locale, bien que ces produits locaux restent peu utilisés dans les habitudes alimentaires quotidiennes.

L'expérimentation réalisée au laboratoire montre que : 1 — l'efficacité de la vidange stomacale est très satisfaisante (98,2 % , 2 — le taux de réalimentation est très élevé 24 heures après la vidange, 3 — la survie, un mois après la vidange, est de 100 % Dans les conditions de pêche électrique, la méthode s'est avérée efficace, la survie au bout de 24 heures étant voisine de celle constatée après une pêche électrique classique. Cette méthode est pratique (le temps de manipulation, par poisson, n'excède pas 1,5 minute, et permet une bonne approche du régime alimentaire du chabot dans les conditions naturelles, sans que le poisson soit sacrifié. Son application entraîne également un gain de temps appréciable par rapport aux méthodes traditionnelles d'étude du régime alimentaire des Poissons.

    2015-10-01

    Full Text Available La présente étude a pour objectif d’analyser les effets probables de la nouvelle stratégie agricole marocaine (le Plan Maroc Vert sur la situation alimentaire (dépendance ou autosuffisance alimentaire du Maroc à l’horizon 2020. Elle a concerné sept produits de base indispensables à la diète marocaine à savoir : le lait, le sucre, l’huile de table, la viande rouge, la viande blanche, le blé tendre et le blé dur. L’approche méthodologique utilisée consiste à prévoir la demande alimentaire du pays, pour l’horizon 2020, en ces denrées. La méthode utilisée pour la prévision de la demande prend en compte la taille de la population, l’élasticité-revenu et l’évolution du niveau de revenu par habitant. La demande projetée est comparée aux niveaux de production prévus par le Plan Maroc Vert pour le même horizon. Ces prévisions ont révélé que malgré les efforts d’augmentation des niveaux de production prévus dans le cadre du Plan Maroc Vert, le Maroc ne pourrait pas atteindre une autosuffisance alimentaire pour le blé tendre, le blé dur, le sucre et les huiles de table à l’horizon 2020. Par contre, cette autosuffisance serait possible pour le lait, les viandes rouges et les viandes blanches. Ces résultats montrent que les décideurs politiques devraient mieux orienter l’intervention de l’Etat pour améliorer l’offre du pays pour le premier groupe des produits. En revanche, les possibilités d’exportation devraient être encouragées pour le deuxième groupe de produits notamment vers les marchés émergents tels que ceux de l’Afrique Subsaharienne.

    International Nuclear Information System (INIS)

    Black shales can be an important source of rare metals such as Cu, Ag, As, Mo, Se, Tl, Cd, platinum group elements (PGE) and gold (Pasava et al., Econ. Geol. 91 (1996) 63). However, especially in the case of noble metals, carriers such as discrete minerals could not be identified. This nuclear microprobe study brings new data on the partition of rare metals in Fe-, Fe (Ni)-, Ni- (Fe)-, Ni- and Zn-sulfides from the Ni-Zn-Mo-PGE mineralized marin black shales (Selwyn Basin, Yukon Territories). Sulfides are present as mineralized vestimentiferan tube-worms which are pyritized. Fluid-mineral interaction led to transformation of these biogenic Fe-sulfides successively to Fe-Ni- and Ni-Fe-sulfides which is indicated by increasing Se contents. Ni-sulfides which are interstital to the tube worms represent remobilized material, they are richest in Se. Several tens to thousands ppm of Cu, Zn, As, Se, Mo were located in the biomineralized and transformed tube worms. Antimony was located in Fe-Ni and Ni-, and Zn sulfides and Ag was present in Fe-Ni and Ni-Fe-sulfides. Pt and Au can also be related to submicron-sized inclusions in Fe-Ni sulfides. Hydrothermal fluids (at least 250 deg. C) precipitated silica around tube worms, intercalating submicron-sized sphalerites. Larger Zn-sulfides contain about 5000 ppm Cd and locally about 60 ppm In. Ba-rich K-feldspar contains Cl-rich Ag-Cd alloys

    The evolution of charged-particle production in collisions of heavy ions at relativistic energies is investigated as function of centrality in a nonequilibrium-statistical framework. Precise agreement with recent d + Au and Au + Au data at sqrt(s_NN) = 200 GeV is found in a Relativistic Diffusion Model with three sources for particle production. Only the midrapidity source comes very close to local equilibrium, whereas the analyses of the overall pseudorapidity distributions show that the systems remain far from statistical equilibrium.

    Full Text Available Cet article porte sur la notion d’« authenticité » appliquée au patrimoine des « vins de terroir ». Ces dix dernières années, des vignerons accusent la législation des AOC (Appellations d’Origine Contrôlées de ne plus protéger les terroirs et de laisser les mauvaises pratiques des vignerons les pervertir. Le retour vers la qualité de terroir repose donc la question de l’identification de la nature authentique de ce patrimoine alimentaire. Pour mener cette approche réflexive, une première partie est consacrée à une revue de littérature sur la notion d’« authenticité ». Une seconde partie analyse les questions et les pratiques déployées par les vignerons pour retrouver l’« authenticité » des terroirs exprimée par les vins ; et enfin les difficultés rencontrées au moment de concevoir une procédure de jugement de cette dernière. L’article montre que loin d’être une donnée objective non discutable, ou bien une simple illusion, l’« authenticité » des vins de terroir est un résultat attaché à l’ensemble des activités qui la font advenir.This article focuses on the notion of authenticity attributed to terroir wines as part of food heritage. Over the past ten years, the AOC system (protected designation of origin has come under attack from wine growers on the grounds that it no longer protects lands and vineyards, leaving them at the mercy of bad practice. The return of quality terroir therefore brings us back to the problem of proving the authenticity of this particular food heritage. The present study begins with a review of literature based on the notion of authenticity. It then explores the different methods used by wine growers to rediscover the ‘genuine’ taste of terroir and express it in their wines. It concludes by looking into the difficulties of designing a wine-tasting procedure capable of judging whether or not a wine really does express its terroir. The article shows

  2. Canada's nuclear export policy

    International Nuclear Information System (INIS)

    The factors influencing the evolution of Canada's nuclear export policy are examined. Initially, nuclear technology was exported to establish an industry in Canada and to share the technology with other countries. After 1974 an increasingly broad range of political and social factors were taken into account and safeguards became the dominant factor. The indirect impacts of the new policy fall into two groups. One consists of the effects of Canada's leadership in taking a tough stand on safeguards. The second group of effects involve the concern of other countries about access to secure energy supplies and advanced technology. (O.T.)

  7. Uranium in Canada

    International Nuclear Information System (INIS)

    In 1974 the Minister of Energy, Mines and Resources (EMR) established a Uranium Resource Appraisal Group (URAG) within EMR to audit annually Canada's uranium resources for the purpose of implementing the federal government's uranium export policy. A major objective of this policy was to ensure that Canadian uranium supplies would be sufficient to meet the needs of Canada's nuclear power program. As projections of installed nuclear power growth in Canada over the long term have been successively revised downwards (the concern about domestic security of supply is less relevant now than it was 10 years ago) and as Canadian uranium supply capabilities have expanded significantly. Canada has maintained its status as the western world's leading exporter of uranium and has become the world's leading producer. Domestic uranium resource estimates have increased to 551 000 tonnes U recoverable from mineable ore since URAG completed its last formal assessment (1982). In 1984, Canada's five primary uranium producers employed some 5800 people at their mining and milling operations, and produced concentrates containing some 11 170 tU. It is evident from URAG's 1984 assessment that Canada's known uranium resources, recoverable at uranium prices of $150/kg U or less, are more than sufficient to meet the 30-year fuelling requirements of those reactors that are either in opertaion now or committed or expected to be in-service by 1995. A substantial portion of Canada's identified uranium resources, recoverable within the same price range, is thus surplus to Canadian needs and available for export. Sales worth close to $1 billion annually are assured. Uranium exploration expenditures in Canada in 1983 and 1984 were an estimated $41 million and $35 million, respectively, down markedly from the $128 million reported for 1980. Exploration drilling and surface development drilling in 1983 and 1984 were reported to be 153 000 m and 197 000 m, respectively, some 85% of which was in

    2003-01-01

    A 1989 all-party motion of parliament called for the elimination of child poverty in Canada by the year 2000. Despite a series of policy initiatives, recent reports suggest that the child poverty rate may now be comparable to that in 1989. The apparent persistence of child poverty in Canada might reflect socioeconomic developments, or something about the way that child poverty is measured. Using micro data covering the period 1986 to 2000 we find little support for these explanations.

    In this talk I will review PHOBOS data on charged particle multiplicities, obtained in Au+Au and d+Au collisions at RHIC. The general features of the Au+Au pseudorapidity distributions results will be discussed and compared to those of /line{p}p collisions. The total charged particle multiplicity, scaled by the number of participant pairs, is observed to be about 40% higher in Au+Au collisions than in /line{p}p and d+Au systems, but, surprisingly at the same level of e+e- collisions. Limiting fragmentation scaling is seen to be obeyed in Au+Au collisions.

    Full Text Available The Local Know-how in the Valorisation of (Dacryodes edulis (G. Don H.J. Lam Fruits in Cameroon. Dacryodes edulis (G. Don H.J. Lam (Burseraceae is an oleaginous plant highly appreciated in the forest zone of Cameroon. This tree yields fruits called african pear or safou, highly consumed by local populations and even abroad. African pear is at the centre of a great economic activity in the Central Africa subregion as its trade generates cash for local traders during the production period. However, the valorisation of african pear is hindered by its high perishable nature responsible for important post-harvest losses due to lack of proper post-harvest handling. Some studies addressed the problem, unfortunately, nothing was done on the local know-how which has still to be investigated. The present paper sheds light on african pear local harvesting, handling and marketing practices in Cameroon. Field surveys were carried out in different production zones in Cameroon savannah and humid forest lowlands: Adamawa, centre, east, littoral and west provinces. Results showed that african pear occupies an important place in the population daily life. This multipurpose tree specie appears to be a source of foodstuffs, cash income, drugs and wood. If, on one hand diverse strategies are developed by the population for a proper conservation of fruits, on the other hand there is not a real fruits transformation activity. Results of this study highlight the traditional know-how and bring out prospects for future works on african pear valorisation.

  5. Uranium in Canada

    International Nuclear Information System (INIS)

    In 1988 Canada's five uranium producers reported output of concentrate containing a record 12,470 metric tons of uranium (tU), or about one third of total Western world production. Shipments exceeded 13,200 tU, valued at $Cdn 1.1 billion. Most of Canada's uranium output is available for export for peaceful purposes, as domestic requirements represent about 15 percent of production. The six uranium marketers signed new sales contracts for over 11,000 tU, mostly destined for the United States. Annual exports peaked in 1987 at 12,790 tU, falling back to 10,430 tU in 1988. Forward domestic and export contract commitments were more than 70,000 tU and 60,000 tU, respectively, as of early 1989. The uranium industry in Canada was restructured and consolidated by merger and acquisition, including the formation of Cameco. Three uranium projects were also advanced. The Athabasca Basin is the primary target for the discovery of high-grade low-cost uranium deposits. Discovery of new reserves in 1987 and 1988 did not fully replace the record output over the two-year period. The estimate of overall resources as of January 1989 was down by 4 percent from January 1987 to a total (measured, indicated and inferred) of 544,000 tU. Exploration expenditures reached $Cdn 37 million in 1987 and $59 million in 1988, due largely to the test mining programs at the Cigar Lake and Midwest projects in Saskatchewan. Spot market prices fell to all-time lows from 1987 to mid-1989, and there is little sign of relief. Canadian uranium production capability could fall below 12,000 tU before the late 1990s; however, should market conditions warrant output could be increased beyond 15,000 tU. Canada's known uranium resources are more than sufficient to meet the 30-year fuel requirements of those reactors in Canada that are now or are expected to be in service by the late 1990s. There is significant potential for discovering additional uranium resources. Canada's uranium production is equivalent, in

  9. Nuclear insurance in Canada

    International Nuclear Information System (INIS)

    Many years ago, a group of insurance companies founded an organization offering nuclear insurance, called Nuclear Insurance Association of Canada. The passage of Order-in-Council P.C. 1960-555 gave Atomic Energy of Canada Ltd. the power to indemnify suppliers, contractors, etc. against liability claims. The situation has remained essentially unchanged. In 1970 Parliament passed the Nuclear Liability Act, but it has never been proclaimed. The act sets mandatory levels of nuclear insurance as high as $75 million for firms involved in nuclear activity. It is expected that agreement between the insurers and government will be reached later this year (1976), so that the act can be proclaimed. (N.D.H.)

  2. Canada's Global Partnership Program

    International Nuclear Information System (INIS)

    Curbing the proliferation of biological weapons (BW) is an essential element of the Global Partnership Against the Spread of Weapons and Materials of Mass Destruction. At the Kananaskis Summit in June 2002, G8 Leaders committed to prevent terrorists, or those that harbour them, from acquiring or developing biological weapons and related materials, equipment and technology. To this end, Canada's Global Partnership Program is investing heavily in biological non-proliferation activities in countries of the former Soviet Union. A comprehensive strategy has been developed to help improve biological safety (biosafety) and biological security (biosecurity) with provision for addressing dual-use concerns. Raising awareness and creating a self-sustaining culture of biosecurity is a key driver of the program. Through this strategy, Canada is assisting various FSU countries to: develop and implement effective and practical biosafety/biosecurity standards and guidelines; establish national and/or regional biosafety associations; develop and deliver effective biosafety and biosecurity training; put in place enhanced physical security measures and equipment. In addition to biosafety and biosecurity, the GPP supports a broad range of Biological Non-Proliferation projects and initiatives, including dozens of projects aimed at redirecting former biological weapons scientists. To date, most of these activities have been supported through Canada's contribution to the International Science and Technology Center (ISTC) and the Science and Technology Centre Ukraine (STCU).(author)

  3. Canada's reactor exports

    International Nuclear Information System (INIS)

    A brief sketch of the development of Canada's nuclear exports is presented and some of the factors which influence the ability to export reactors have been identified. The potential market for CANDUs is small and will develop slowly. The competition will be tough. There are few good prospects for immediate export orders in the next two or three years. Nonetheless there are reasonable opportunities for CANDU exports, especially in the mid-to-late 1980s. Such sales could be of great benefit to Canada and could do much to sustain the domestic nuclear industry. Apart from its excellent economic and technical performance, the main attraction of the CANDU seems to be the autonomy it confers on purchasing countries, the effectiveness with which the associated technology can be transferred, and the diversification it offers to countries which wish to reduce their dependence on the major industrial suppliers. Each sales opportunity is unique, and marketing strategy will have to be tailored to the customer's needs. Over the next decade, the factors susceptible to Canadian government action which are most likely to influence CANDU exports will be the political commitment of the government to those reactor exports, the performance established by the four 600 MWe CANDUs now nearing completion, the continuing successful operation of the nuclear program in Ontario, and the co-ordination of the different components of Canada's nuclear program (AECL, nuclear industry, utilities, and government) in putting forth a coherent marketing effort and following through with effective project management

  4. Environmental performance reviews: Canada

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2004-09-01

    OECD's comprehensive 2004 report on Canada's environmental policies and programmes systematically examines policy related to air, water, and nature/biodiversity as well as the interface between environmental policy and economic policy, social policy, and specific sectors. It finds that while Canada has made satisfactory progress since 1985, there are still significant challenges, and the report makes specific recommendations for more use of economic instruments and use of the polluter and user pays principles, rationalising water governance, strengthening nature protection, reducing energy intensity, implementing climate change policies, reviewing environmentally related taxes, and implementing marine and aid commitments. Coal provides about 20% of Canada's electric power. Most direct subsidisation of the fossil fuel supply industries (upstream oil, gas and coal) has been reduced. The report recommends subsidies to the mining industry for exploration should also be phased out. Recent measurements indicate emissions of mercury are increasing, mainly due to long-range transboundary air pollution from coal-burning plants. 42 figs., 24 tabs.

  5. Transnational surrogacy: Canada's contradictions.

    Science.gov (United States)

    Lozanski, Kristin

    2015-01-01

    Transnational commercial surrogacy represents a form of medical tourism undertaken by intended parents who seek to hire women in other countries, increasingly often in the global South, as surrogates. While much of the scholarly literature focuses on the conditions of surrogacy within host countries, such as India, there has been limited analysis of transnational surrogacy focused upon origin countries. In this article, I build upon the scholarship that explores the impact of host country structures on transnational surrogacy, with special attention to the significance of Canadian citizenship policy through analysis of legislation and policy vis-à-vis transnational commercial surrogacy. The Canadian case demonstrates clear contradictions between the legislation and policy that is enacted domestically to prohibit commercial surrogacy within Canada and legislation and policy that implicitly sanctions commercial surrogacy through the straightforward provision of citizenship for children born of such arrangements abroad. The ethical underpinnings of Canada's domestic prohibition of commercial surrogacy, which is presumed to exploit women and children and to impede gender equality, are violated in Canada's bureaucratic willingness to accept children born of transnational commercial surrogacy as citizens. Thus, the ethical discourses apply only to Canadian citizens within Canadian geography. The failure of the Canadian government to hold Canadian citizens who participate in transnational commercial surrogacy to the normative imperatives that prohibit the practice within the country, or to undertake a more nuanced, and necessarily controversial, discussion of commercial surrogacy reinforces transnational disparities in terms of whose bodies may be commodified as a measure of gendered inequality.

    MOREAU J.

    1979-10-01

    Full Text Available Des observations réalisées sur deux stations piscicoles de Madagascar, dans des étangs ne recevant ni engrais ni nourriture, révèlent qu'au cours de leur premier mois les alevins de carpe (C. carpio subissent des mortalités voi-sines de 50 %. Ces dernières sont encore plus élevées en début et en fin de saison de reproduction. Au début, les fortes mortalités sont dues à la température trop basse et aux disponibilités alimentaires insuffisantes ; en fin de saison de reproduction, la température trop élevée et la mauvaise qualité des œufs sont sans doute en cause. Une fumure adéquate des étangs de grossissement des alevins et une alimentation correcte des géniteurs permettront peut-être de diminuer ces mortalités.

  11. Canada's disposal concept

    International Nuclear Information System (INIS)

    A concept for the safe and permanent disposal of nuclear fuel wastes from Canada's CANDU reactors has been developed by Atomic Energy of Canada Ltd. (AECL). The waste would be placed in an engineered disposal vault 500 to 1000 m below the surface in plutonic rock of the Canadian Shield. The multiple barriers to retain the waste and retard the release of radioactivity would be the waste form, the containers, buffer and backfill, and the rock overlying the vault. Numerous research programmes have been carried out to develop the technology for the concept. These include work on materials corrosion and failure mechanisms to assess the performance of the used fuel containers. Predictive modelling has shown that more than 97% of ASTM Grade 2 titanium containers will retain their integrity, even under pessimistic assumptions, for 1200-6000 years after emplacement, and even longer times may be achieved with other grades of titanium or copper. Other research has been aimed at vault sealing, at site characterization for an underground research laboratory and at the development of a methodology for assessing radiological and environmental effects after closure of the facility. A review of the safety and environmental impacts of the concept is now being carried out by an independent panel appointed by the government. (2 figures, 3 references) (UK)

  12. Canada's Clean Air Act

    International Nuclear Information System (INIS)

    This paper provided an outline of Canada's Clean Air Act and examined some of the regulatory changes that will occur as a result of its implementation. The Act is being introduced to strengthen the legislative basis for taking action on reducing air pollution and GHGs, and will allow the government to regulate both indoor and outdoor air pollutants and GHGs. The Act will require the Ministers of the Environment and Health to establish national air quality objectives, as well as to monitor and report on their attainment. The Canadian Environmental Protection Act will be amended to enable the government to regulate the blending of fuels and their components. The Motor Vehicle Fuel Consumption Standards Act will also be amended to enhance the government's authority to regulate vehicle fuel efficiency. The Energy Efficiency Act will also be expanded to allow the government to set energy efficiency standards and labelling requirements for a wider range of consumer and commercial products. The Act will commit to short, medium and long-term industrial air pollution targets. Regulations will be proposed for emissions from industry; on-road and off-road vehicles and engines; and consumer and commercial products. It was concluded that the Government of Canada will continue to consult with provinces, territories, industries and Canadians to set and reach targets for the reduction of both indoor and outdoor air pollutants and GHG emissions. 6 figs

  13. Energy in Canada

    International Nuclear Information System (INIS)

    Canada's historical energy consumption, its current consumption and its likely requirements by the turn of the century are reviewed. It is estimated that at least 50% more energy will be required in the year 2000 than is consumed now, assuming a minimum 2% growth rate in primary energy consumption. Both non-renewable and renewable energy resources are examined in the light of these future energy requirements and the need to substitute alternative energy sources for conventional oil in various end uses. The comparative risks involved in energy production are also reviewed. Most of the increase in energy consumption and the substitution of oil over the next 20 years is likely to be met by conventional energy sources, since indigenous reserves are extensive and the relevant technologies well-established. Coal, nuclear and hydro reserves could cover the increase in energy demand until well into the next century, and natural gas reserves are sufficient to bridge the gap during conversion from oil to other energy sources. Nuclear power using advanced fuel cycles and oil from tar sands offer Canada long-term security. The penetration of unconventional energy sources is likely to be relatively small during the next 20 years. However, the most promising may become significant in the next century. (author)

    Full Text Available Although public policies have for many years spearheaded information campaigns about how eating affects health, rising obesity rates show that the expected effects have yet to be achieved. Why consumers do not practically comply with nutritional recommendations? This question lead the ministry in charge of Agriculture, Food and Fisheries to require in 2010 an updated state of knowledge for peer-reviewed literature and to commission INRA to undertake a collective scientific expertise on dietary behaviours. The aim was to investigate the multiple determinants of behaviours and how behaviours form and change in individuals according to social class and age, but also collectively over a long period of time. The expertise reports that the consumer is subjected to different environmental stimuli which can bias opinion and that dietary behavior can be affected by information strategies combining different tools and targeting individuals or specific groups. This article sets out the conclusions of the expertise report which draws on nearly 1,600 scientific articles from around the world and was prepared by some twenty experts from fields as diverse as epidemiology, nutrition, sociology and economics.

    The magnetic susceptibility of liquid Cr-Au, Mn-Au, Fe-Au and Cu-Au alloys was investigated as a function of temperature and composition. Liquid Cr{sub 1-c}Au{sub c} with 0.5 ≤ c and Mn{sub 1-c}Au{sub c} with 0.3≤c obeyed the Curie-Weiss law with regard to their dependence of χ on temperature. The magnetic susceptibilities of liquid Fe-Au alloys also exhibited Curie-Weiss behavior with a reasonable value for the effective number of Bohr magneton. On the Au-rich side, the composition dependence of χ for liquid TM-Au (TM=Cr, Mn, Fe) alloys increased rapidly with increasing TM content, respectively. Additionally, the composition dependences of χ for liquid Cr-Au, Mn-Au, and Fe-Au alloys had maxima at compositions of 50 at% Cr, 70 at% Mn, and 85 at% Fe, respectively. We compared the composition dependences of χ{sub 3d} due to 3d electrons for liquid binary TM-M (M=Au, Al, Si, Sb), and investigated the relationship between χ{sub 3d} and E{sub F} in liquid binary TM-M alloys at a composition of 50 at% TM.

    The U.S. Geological Survey (USGS) recently assessed the undiscovered oil and gas potential of the West Greenland?East Canada Province as part of the USGS Circum-Arctic Oil and Gas Resource Appraisal effort. The West Greenland?East Canada Province is essentially the offshore area between west Greenland and east Canada and includes Baffin Bay, Davis Strait, Lancaster Sound, and Nares Strait west of and including Kane Basin. The tectonic evolution of the West Greenland?East Canada Province led to the formation of several major structural domains that are the geologic basis for the five assessment units (AU) defined in this study. The five AUs encompass the entire province. Each AU was assessed in its entirety for undiscovered, technically recoverable (assuming absence of sea ice) oil and gas resources, but the assessment results reported here are only for those portions of each AU that are north of the Arctic Circle, as that latitude defines the area of the Circum-Arctic oil and gas assessment.

  5. Western Canada uranium perspective

    International Nuclear Information System (INIS)

    The current situation in the exploration for uranium in British Columbia, the Yukon, the Northwest Territories, and Saskatchewan is reviewed. A moratorium on exploration has been in effect in British Columbia since 1980; it is due to expire in 1987. Only the Blizzard deposit appears to have any economic potential. The Lone Gull discovery in the Thelon Basin of the Northwest Territories has proven reserves of more than 35 million pounds U3O8 grading 0.4%. Potentially prospective areas of the northern Thelon Basin lie within a game sanctuary and cannot be explored. Exploration activity in Saskatchewan continues to decline from the peak in 1980. Three major deposits - Cluff Lake, Rabbit Lake and Key Lake - are in production. By 1985 Saskatchewan will produce 58% of Canada's uranium, and over 13% of the western world's output. (L.L.)

    This paper examines the distribution of gambling dollars in Nova Scotia, Saskatchewan and Canada and studies the impact of this spending on households. We focus first on how gambling expenditures are related to the level and source of household income as well as to other demographic characteristics such as age, education, household composition, geographical area, and sources of income. Next we analyze how gambling expenditures are distributed among those households that gamble. We show how expenditure patterns differ in the intensity of gambling as measured by the proportion of household income or total amount of dollars spent on gambling. Then we study the affects that gambling has on spending on household necessities, changes in net worth, retirement savings and household debt. Finally we determine whether gambling expenditures act as a substitute or a complement to other recreational spending on entertainment products and services. Throughout the paper we offer a comparative analysis of provincial and national data. PMID:15353922

Life expectancy in Canada continues to rise and is high compared with most OECD countries; however, infant and maternal mortality rates tend to be worse than in countries such as Australia, France and Sweden. About 70% of total health expenditure comes from the general tax revenues of the federal, provincial and territorial governments. Most public revenues for health are used to provide universal medicare (medically necessary hospital and physician services that are free at the point of service for residents) and to subsidise the costs of outpatient prescription drugs and long-term care. Health care costs continue to grow at a faster rate than the economy and government revenue, largely driven by spending on prescription drugs. In the last five years, however, growth rates in pharmaceutical spending have been matched by hospital spending and overtaken by physician spending, mainly due to increased provider remuneration. The governance, organization and delivery of health services is highly decentralized, with the provinces and territories responsible for administering medicare and planning health services. In the last ten years there have been no major pan-Canadian health reform initiatives but individual provinces and territories have focused on reorganizing or fine tuning their regional health systems and improving the quality, timeliness and patient experience of primary, acute and chronic care. The medicare system has been effective in providing Canadians with financial protection against hospital and physician costs. However, the narrow scope of services covered under medicare has produced important gaps in coverage and equitable access may be a challenge in these areas. PMID:23628429

  10. Canada No. 1 in business

    International Nuclear Information System (INIS)

    Canada has for the fifth time in a row been chosen the best industrialized country in the world in which to initiate and run a business. The Norwegian interest in Canada has grown strongly the last years and Norwegian companies have invested over 20 billion NOK there. Canada is the perfect gateway to the large markets in the USA. Norway is currently Canada's 15th largest trading partner. In addition to low costs and strategic location, Canada has the most highly educated workforce in the world. A company on the Canadian side of the US border has the same access to the American market as a US-based company. There is even a Norwegian company in Canada that exports 100 per cent of its products across the border to the USA. The trade between the USA and Canada is more extensive than between the USA and all the EU countries together. Furthermore, Canadian companies concentrating on research and education are given a generous tax credit

    We present here a technological platform for engineering Au nanotopographies by templated electrodeposition on antibacterial surfaces. Three different types of nanostructures were fabricated: nanopillars, nanorings and nanonuggets. The nanopillars are the basic structures and are 50 nm in diameter and 100 nm in height. Particular arrangement of the nanopillars in various geometries formed nanorings and nanonuggets. Flat surfaces, rough substrate surfaces, and various nanostructured surfaces were compared for their abilities to attach and kill bacterial cells. Methicillin-resistant Staphylococcus aureus, a Gram-positive bacterial strain responsible for many infections in health care system, was used as the model bacterial strain. It was found that all the Au nanostructures, regardless their shapes, exhibited similar excellent antibacterial properties. A comparison of live cells attached to nanotopographic surfaces showed that the number of live S. aureus cells was technological platform for engineering Au nanotopographies by templated electrodeposition on antibacterial surfaces.

  16. Magnetic susceptibilities of liquid Cr-Au, Mn-Au and Fe-Au alloys

    International Nuclear Information System (INIS)

    The magnetic susceptibility of liquid Cr-Au, Mn-Au, Fe-Au and Cu-Au alloys was investigated as a function of temperature and composition. Liquid Cr1-cAuc with 0.5 ≤ c and Mn1-cAuc with 0.3≤c obeyed the Curie-Weiss law with regard to their dependence of χ on temperature. The magnetic susceptibilities of liquid Fe-Au alloys also exhibited Curie-Weiss behavior with a reasonable value for the effective number of Bohr magneton. On the Au-rich side, the composition dependence of χ for liquid TM-Au (TM=Cr, Mn, Fe) alloys increased rapidly with increasing TM content, respectively. Additionally, the composition dependences of χ for liquid Cr-Au, Mn-Au, and Fe-Au alloys had maxima at compositions of 50 at% Cr, 70 at% Mn, and 85 at% Fe, respectively. We compared the composition dependences of χ3d due to 3d electrons for liquid binary TM-M (M=Au, Al, Si, Sb), and investigated the relationship between χ3d and EF in liquid binary TM-M alloys at a composition of 50 at% TM

    A short bulletin from the National Fusion Program highlighting in this issue Canada-Europe Accords: 5 year R and D collaboration for the International Thermonuclear Experimental Reactor (ITER) AECL is designated to arrange and implement the Memorandum of Understanding (MOU) and the ITER Engineering Design Activities (EDA) while EUROTAM is responsible for operating Europe's Fusion R and D programs plus MOU and EDA. The MOU includes tokamaks, plasma physics, fusion technology, fusion fuels and other approaches to fusion energy (as alternatives to tokamaks). STOR-M Tokamak was restarted at the University of Saskatchewan following upgrades to the plasma chamber to accommodate the Compact Toroid (CT) injector. The CT injector has a flexible attachment thus allowing for injection angle adjustments. Real-time video images of a single plasma discharge on TdeV showing that as the plasma density increases, in a linear ramp divertor, the plasma contact with the horizontal plate decreases while contact increases with the oblique plate. Damage-resistant diffractive optical elements (DOE) have been developed for Inertial Confinement Fusion (ICF) research by Gentac Inc. and the National Optics Institute, laser beam homogeniser and laser harmonic separator DOE can also be made using the same technology. Studies using TdeV indicate that a divertor will be able to pump helium from the tokamak with a detached-plasma divertor but helium extraction performance must first be improved, presently the deuterium:helium retention radio-indicates that in order to pump enough helium through a fusion reactor, too much deuterium-tritium fuel would be pumped out. 2 fig

    International Nuclear Information System (INIS)

    Current petroleum industry activities on Canada's east coast, and future potential were discussed. Offshore drilling activity is proceeding in the Jeanne d'Arc Basin, in addition to the Sable and Terra Nova Offshore Energy Projects. Future potential for Newfoundland and Nova Scotia has been estimated at 30 billion BOE and 13 billion BOE respectively. Natural gas potential off Labrador was estimated at 37 Tcf, offshore Newfoundland at 41 Tcf, and offshore Sable Island at 49 Tcf with varying amounts of oil associated with each field. Cumulative industry spending is expected to reach $ 10 billion by the year 2000, and could reach $20 billion by 2005. Prospects for Mobil Oil, number One in discoveries and industry influence, and number Two in acreage among the partners, were reviewed. Some details of the Sable Offshore Energy Project were outlined. The estimated cost of the project is $2 billion. It is expected to be on stream in late 1999 with a total of 27 wells (11 in phase 1). Reserves are estimated at 3.5 TCF or more. Hibernia was on stream in November 1997. Total recoverable reserves at Hibernia are estimated at 750 MMBls. Peak production of 180,000 b/d is expected by 2000-2001. Life expectancy of 20 years is predicted. The Terra Nova project, located 25 miles southeast of Hibernia, was also reviewed. It will be on stream in late 2000 with total reserves of 350-450 MMBls of oil, peak production at 115,000 to 135,000 b/d with a life expectancy of 15 years. 21 figs

  4. SCWR Concept in Canada

    International Nuclear Information System (INIS)

    AECL is designing the Canadian SCWR concept, which has evolved from the well-established pressuretube type CANDU® reactor. The Canadian SCWR is designed to produce electrical energy as the main product, plus process heat, hydrogen, industrial isotopes, and drinking water (through the desalination process) as supplementary products, all within a more compact reactor building. Another potential application of the available co-generated process heat is the extraction and refining of oil sands, which is presently achieved using co-generation with natural gas turbines and process heat. The extraction and upgrading process requires: thermal power to lower the viscosity and extract the oil; electric power for separation and refining equipment; and hydrogen gas for upgrading the oil product prior to transport. A National Program has been established in Canada to support R&D studies for the Canadian SCWR design. It covers key areas of interest (such as thermal hydraulics, safety, materials, and chemistry) to participants in the Generation-IV International Forum (GIF) SCWR designs. Results generated from the program are contributed to the GIF SCWR project management boards (PMBs). For example, heat transfer correlations have been derived using experimental data primarily obtained from fossil-plant related studies (which were started as early as 1930s. Materials and chemistry studies have evolved from operating experience of fossil-fired power plants to a) develop, and perform targeted testing of, materials for key components, in particular in-core reactor components that will be exposed to conditions not encountered in a fossil-fired boiler (such as irradiation and water radiolysis), and b) develop a suitable water chemistry to minimize corrosion and corrosion product transport

    Full Text Available L'approvisionnement quotidien en nourriture est, en règle générale, le principal facteur limitant de productions à grande échelle de jeunes poissons marins.La pêche de plancton dans la nature a été, et reste, le moyen d'expérimentation le plus immédiat, et le plus satisfaisant sur le plan qualitatif. Mais la récolte des quantités nécessaires, au moment voulu, devient très délicate dès que l'on dépasse l'échelle de l'aquarium. Le développement, ces dernières décennies, de techniques de production en masse d'animaux-proies a permis le lancement d'élevages à grande échelle. Parmi ces proies, le Branchiopode Artemia salina et le Rotifère Brachionus plicatilis dominent incontestablement ; tandis que l'élevage des Copépodes, part la plus intéressante du plancton naturel, reste encore mal maîtrisé. Cependant , l'élevage et l'emploi de proies vivantes, quelles qu'elles soient, imposent la réalisation d'installations coûteuses et l'emploi d'un abondant personnel qualifié. Il en est résulté récemment un important effort de recherche en direction de nourritures inertes, broyats , poudres et aliments composés, généralement abandonnés après les échecs enregistrés pendant les premières années du siècle. Quelques résultats encourageants ont été obtenus, mais ils restent limités et soulèvent de délicats problèmes d'hygiène des bacs d'élevage. L'emploi de proies vivantes , au moins pendant le premier mois des élevages , reste donc encore une obligation. Dans ce contexte, l'essentiel de l'effort actuel tend , d'une part à réduire leur durée d'emploi au minimum possible et, d'autre part, à rendre leur production plus rationnelle , en recherchant des méthodes qui évitent, pour leur alimentation , de faire appel à des algues planctoniques vivantes.

    Full Text Available Abstract The use of nanowires (NWs for labeling, sensing, and sorting is the basis of detecting biomolecules attached on NWs by optical and magnetic properties. In spite of many advantages, the use of biomolecules-attached NWs sensing by photoelectrochemical (PEC study is almost non-existent. In this article, the PEC study of dye-attached single-stranded DNA on Au NWs and Au-Ni-Au multilayer NWs prepared by pulse electrodeposition are investigated. Owing to quantum-quenching effect, the multilayer Au NWs exhibit low optical absorbance when compared with Au NWs. The tagged Au NWs show good fluorescence (emission at 570 nm, indicating significant improvement in the reflectivity. Optimum results obtained for tagged Au NWs attached on functionalized carbon electrodes and its PEC behavior is also presented. A twofold enhancement in photocurrent is observed with an average dark current of 10 μA for Au NWs coated on functionalized sensing electrode. The importance of these PEC and optical studies provides an inexpensive and facile processing platform for Au NWs that may be suitable for biolabeling applications.

  16. Western Canada Sedimentary Basin competitiveness

    International Nuclear Information System (INIS)

    Recent dramatic expansion of the natural gas industry in the Western Canada Sedimentary Basin provided ample proof of the potential of this area for further development of natural gas supply. However, the inherent competitive advantages provided by the Western Canada Sedimentary Basin were said to have been offset by low netback prices resulting in poor producer economics when competitiveness is measured by availability of opportunities to find and develop gas supply at costs low enough to ensure attractive returns. Technology was identified as one of the key elements in improving basin competitiveness, but the greatest potential lies in reduced transportation costs and increased access to North American market centres. 8 figs

  1. Canada's commitment to nuclear technology

    International Nuclear Information System (INIS)

    This paper gives a broad update on all facets of the Canadian nuclear industry and demonstrates Canada's continuing commitment to nuclear technology. Canada has developed a global leadership position in nuclear technology for power generation, uranium production and isotope supply. This commitment is being further enhanced by successes in international markets with Candu technology, new uranium mine developments in our province of Saskatchewan, and expanding isotope capabilities including the construction of two new production reactors. Korea's economy is benefiting through collaboration with Canada's leading nuclear companies, both in Korea and Canada. These collaborations have the potential to expand considerably with the implementation of the Kyoto Framework Convention on Climate Change and the anticipated increased demand for new nuclear power generation installations in all major global markets. Much has been publicized about the situation surrounding Ontario Hydro Nuclear and its nuclear recovery program. This paper gives the background and highlights the actions within Ontario and Ontario Hydro designed to ensure the long term recovery of all twenty nuclear units in Ontario. The presentation at the conference will bring the audience completely up-to-date on recent events. (author)

  3. Canada-China power experience

    International Nuclear Information System (INIS)

    International energy opportunities were reviewed, with emphasis on China, and on Canada-China Power Inc., alternatively known as 'Team Canada'. Canada-Chine Power Inc., is a company founded by three of Canada's leading engineering consulting firms, i.e., Monenco AGRA Inc., SNC Lavalin Inc., and Acres International Limited. An office was established in Beijing in January 1994. Other Canadian manufacturers and engineering companies also have been actively pursuing hydro power opportunities in China for several years in view of China's enormous demand for power. It was estimated that by the year 2000, China will install 137 GW of new capacity, and foreign investment will account for approximately a third of the growth. AGRA is working on a 5400 MW thermal plant on Hainan Island, and is in final negotiations with the Yangtze Three Gorges Development Corporation for a management information system for their 18200 MW multi-purpose project. Criteria used by AGRA to identify international opportunities include: (1) a large capital spending program in fields with capabilities, expertise and past experience, (2) access to international funding, (3) competitive Canadian technology, and (4) an acceptable business and cultural climate. In assessing the opportunities, AGRA decided to concentrate on providing technologies in greatest need, such as project management systems, computer engineering and CAD systems, and clean coal technology

  5. Canada report on bioenergy 2008

    International Nuclear Information System (INIS)

    Canada is a nation rich in fossil fuel resources. Canada has a large, well-developed forest sector and is one of the world's largest exporters of wood products. Although national bioenergy policies exist, provincial policies regarding forest resources are necessary because 77 per cent of Canada's forests are under provincial jurisdiction. This report presented an update on Canada's bioenergy policy and resources. The report discussed biomass resources such as woody biomass; agricultural residues; and municipal waste. The use of biomass was presented with particular reference to heat and power; biofuels production; pyrolysis oil; wood pellets; and trends in biomass production and consumption. Current biomass users and biomass prices were also examined. Last, the report addressed imports and exports of ethanol, biodiesel, pyrolysis oil, and wood pellets as well as barriers and opportunities to trade. A list of Canadian bioenergy initiatives and programs was also provided. It was concluded that the greatest opportunities for trade are to succeed in research on super-densified pellets; raise ocean shipping capacity to bring down rates; and to establish and entire biomass industry in Newfoundland Labrador. 20 tabs., 8 figs., 1 appendix

  9. Multifragmentation in Au + Au collisions studied with AMD-V

    International Nuclear Information System (INIS)

    AMD-V is an optimum model for calculation of multifragmentation in Au + Au collisions. AMD-V consider anti-symmetry of incident nucleus, target nucleus and fragments, furthermore, it treat the quantum effect to exist many channels in the intermediate and final state. 150 and 250 MeV/nucleon incident energy were used in the experiments. The data of multifragment atom in 197Au + 197Au collisions was reproduced by AMD-V calculation using Gognny force, corresponding to the imcompressibility of nuclear substance K = 228 MeV and its mean field depend on momentum. When other interaction (SKG 2 force, corresponding to K = 373 KeV) was used an mean field does not depend on momentum, the calculation results could not reproduce the experimental values, because nucleus and deuteron were estimated too large and α-particle and intermediate fragments estimated too small.

    2007-01-01

    Ce volume collectif sur le risque inaugure la collection L'ÉQUINOXE. Ancré dans l'histoire pour mesurer les continuités et les ruptures, il illustre la manière dont les sciences humaines évaluent et mesurent les enjeux collectifs du risque sur les plans politiques, scientifiques, énergétiques, juridiques et éthiques. Puisse-t-il nourrir la réflexion sur la culture et la prévention du risque. Ses formes épidémiques, écologiques, sociales, terroristes et militaires nourrissent les peurs actuelles, structurent les projets sécuritaires et constituent - sans doute - les défis majeurs à notre modernité. Dans la foulée de la richesse scientifique d'Equinoxe, L'ÉQUINOXE hérite de son esprit en prenant à son tour le pari de contribuer - non sans risque - à enrichir en Suisse romande et ailleurs le champ éditorial des sciences humaines dont notre société a besoin pour forger ses repères.

  12. Environmental radioactivity in Canada 1986

    International Nuclear Information System (INIS)

    The radiological surveillance program of the Department of National Health and Welfare is conducted for the purpose of determining levels of environmental radioactivity in Canada and assessing the resulting population exposures. During 1986 the program was strongly influenced by radioactive fallout on Canada resulting from the Chernobyl nuclear reactor accident on April 26, 1986 in the Soviet Ukraine. The Environmental Radiation Hazards Division (ERHD) increased its frequency of analyses of environmental samples immediately following the accident. Interim screening limits for foodstuffs were developed. A measurement program for radioactivity in domestic and imported foods was implemented. The ERHD measurement program was supplemented by additional measurements conducted by many other private and government laboratories. Radiation doses to Canadian from Chernobyl fallout were extremely low with no group in the population receiving more than 10 microsieverts

  14. Fusion energy and Canada's role

    International Nuclear Information System (INIS)

    Fusion is the process of releasing energy from matter which occurs in our sun. Canada is contributing to the development of technology which will permit this process to be harnessed and made available on earth. The international effort has increased from a modest beginning in the 1950s to a level of approximately two billion dollars annually in the 1980s. The purpose of this booklet is to introduce the concept of fusion energy as a technology which should make an important addition to the mix of energy sources for our future. Through a co-ordinated approach, Canada has established several projects which will contribute significantly to the development of technologies in specific areas leading to opportunities now for Canadian industry in the international effort

    While the overall climate for women physicists both in academia and industry has improved significantly over the past decade in Canada, it will be some time before women are well represented. Numbers of women in physics at all academic levels have increased, but are less than ideal at the full professor level. Organizations such as the Canadian Association of University Teachers and local initiatives are striving to minimize the socio-economic and professional gaps between women and men. The Canadian Association of Physicists, through its Committee to Encourage Women in Physics, and the Natural Sciences and Engineering Research Council are supportive and serve as catalysts, bringing together men and women to discuss and address issues concerning women in physics across Canada.

  16. Nuclear criticality safety in Canada

    International Nuclear Information System (INIS)

    The approach taken to nuclear criticality safety in Canada has been influenced by the historical development of participants. The roles played by governmental agencies and private industry since the Atomic Energy Control Act was passed into Canadian Law in 1946 are outlined to set the scene for the current situation and directions that may be taken in the future. Nuclear criticality safety puts emphasis on the control of materials called special fissionable material in Canada. A brief account is given of the historical development and philosophy underlying the existing regulations governing special fissionable material. Subsequent events have led to a change in emphasis in the regulatory process that has not yet been fully integrated into Canadian legislation and regulations. Current efforts towards further development of regulations governing the practice of nuclear criticality safety are described. (auth)

    International Nuclear Information System (INIS)

    Despite all the current difficulties, previous erroneous forecasts and other mistakes, the longer term future looks good for uranium mining and for Canada's industry in particular. Saskatchewan continues to offer the most exciting new prospects, the huge and fabulously high grade Cigar Lake deposits being the most spectacular of the recent discoveries. Notwithstanding continuous mining for 30 years from Elliot Lake there still remain there significant uncommitted reserves which can be developed when the market for uranium is in better balance

  20. The nuclear debate in Canada

    International Nuclear Information System (INIS)

    The author argues that the nuclear debate in Canada is concerned less with the safety of nuclear power plants and more with arguments of economics and social decision-making. The nuclear industry cannot afford to neglect the continuing need to inform the public about nuclear risks. But there is also a need to develop specific arguments to increase public acceptance of nuclear energy as an economic, democratic and equitable energy option

  1. Indigenous Educational Attainment in Canada

    Directory of Open Access Journals (Sweden)

    Catherine E. Gordon

    2014-06-01

    Full Text Available In this article, the educational attainment of Indigenous peoples of working age (25 to 64 years in Canada is examined. This diverse population has typically had lower educational levels than the general population in Canada. Results indicate that, while on the positive side there are a greater number of highly educated Indigenous peoples, there is also a continuing gap between Indigenous and non-Indigenous peoples. Data also indicate that the proportion with less than high school education declined, which corresponds with a rise of those with a PSE; the reverse was true in 1996. Despite these gains, however, the large and increasing absolute numbers of those without a high school education is alarming. There are intra-Indigenous differences: First Nations with Indian Status and the Inuit are not doing as well as non-Status and Métis peoples. Comparisons between the Indigenous and non-Indigenous populations reveal that the documented gap in post-secondary educational attainment is at best stagnant. Out of the data analysis, and based on the history of educational policy, we comment on the current reform proposed by the Government of Canada, announced in February of 2014, and propose several policy recommendations to move educational attainment forward.

  2. Routine outcome measures in Canada.

    Kisely, Steve; Adair, Carol E; Lin, Elizabeth; Marriott, Brian

    2015-01-01

    Canada is a federal country of 10 provinces and three territories. High level information on mental health conditions and service use has mostly been generated from administrative data collected by provinces and territories. These include four major types - hospital admissions and discharges, physician billings, ambulatory care services, and drug databases. At the national level, the Canadian Institute for Health Information brings together this information to produce indicators of outcome. Although these data provide information on patient and health system characteristics, they do not capture the full spectrum of formal and informal mental healthcare. These include changes in health status, functioning, community integration and quality of life. As a result, some jurisdictions have begun to implement more standardized measures of outcome such as the clinician-rated Health of the Nation Outcome Scales or the inpatient Resident Assessment Instrument - Mental Health. In this paper we provide an overview of mental-health-related data sources in Canada, highlight some of the more progressive practices beginning to emerge, and conclude with some thoughts about how the routine measurement and reporting of mental health outcomes in Canada might be advanced including efforts at engaging both clinicians and decision-makers.

  3. Overview of Canada's uranium industry

    International Nuclear Information System (INIS)

    This paper places Canada's uranium industry in its international context. Most uranium, except that produced in the United States, is traded internationally. A brief history of the industry worldwide is given to show how the principal producing areas have fared to date. The industry is young, highly cyclical, and still far from achieving stability. Uranium is a single end-use commodity, entirely dependent on the generation of electricity in nuclear stations, and is without price elasticity: lowering the price does not increase demand. The typical nuclear fuel processing chain has not encouraged or led to much vertical integration. Uranium is subject to more governmental control than any other commodity. The principal market is located in the industrial countries of western Europe, the United States, Canada, and the far east. The uranium supply-demand situation is reviewed, including the current and near-term oversupply and the longer term outlook to 1995. The major negative impact of reactor cancellations and deferments in the United States is discussed. Because of the difficulty in getting reactors on line, it has become easier to forecast the demand for uranium over the next 10 years. It is more difficult to predict how that demand will be met from the more than ample competing sources. Canada's potential for supplying a significant portion of this demand is considered in relation to producers and potential new producers in other countries

  4. Education of pharmacists in Canada.

    2008-12-15

    In Canada, the education of pharmacists is built upon a foundation of strong, research-intensive publicly funded universities and a universal health-care system that balances government and private financing for prescription medications. The evolution of pharmacy education and practice in Canada has laid the foundation for a variety of emerging trends related to expanded roles for pharmacists, increasing interprofessional collaboration for patient-centered care, and emergence of pharmacy technicians as a soon-to-be regulated professional group in parts of the country. Current challenges include the need to better integrate internationally educated pharmacists within the domestic workforce and tools to ensure continuous professional development and maintenance of competency of practitioners. Academic pharmacy is currently debating how best to manage the need to enhance the pharmacy curriculum to meet current and future skills needs, and whether a doctor of pharmacy (PharmD) degree ought to become the standard entry-to-practice qualification for pharmacists in Canada.

  5. Women in Physics in Canada

    Science.gov (United States)

    McKenna, Janis

    2012-10-01

    Here we are in the 21st century in Canada, where most of us would say that young girls and boys have equal access to education, opportunities, and careers of their own choice. In Canada, women currently outnumber men in full-time university enrollment, in Medical Schools and in Law Schools. 48% of the Canadian work force is female, yet women make up only 21% of working professionals in science, engineering and technology. Canada-wide in Physics, the situation is such that only 20% of our BSc graduates are women, and 19% of our PhD graduates are women. It is evident that the ``leaky pipeline'' in Physics leaks most at a young age, before BSc graduation. High school physics statistics in BC indicate that while most of the grade 12 science and math disciplines have roughly equal numbers of young men and women enrolled, this is not the case for high school physics, where province-wide, only 30% of Physics 12 students are women. (Biology is also skewed, but in the other direction: 62% of Biology 12 students are women) This poster will present current statistics and will hopefully be a wake-up call for us all to consider participating in more outreach in science, and especially physics, in our high schools.

The grazing habitat of roe deer (Capreolus capreolus L. had been surveyed during spring, summer and automn seasons of 1988 in Lauzelle Woods using 24 enclosed and unenclosed areas in order to measure the degree of stress on the vegetation exerted by the animal and to establish its alimentary regime. In general, in the woods the availability of the vegetation was sufficient for the roe deer and hence they do not exert any stress on the vegetation. Nevertheless, they exert some stress on some vegetation that had low rate of regrowth. The examination of the chemical composition of the fecal matter revealed that the vegetation of Lauzelle Woods provided a good quality forage with 21 % crude protein.

    Abstract Objective To determine the location of Canadian abortion services relative to where reproductive-age women reside, and the characteristics of abortion facilities and providers. Design An international survey was adapted for Canadian relevance. Public sources and professional networks were used to identify facilities. The bilingual survey was distributed by mail and e-mail from July to November 2013. Setting Canada. Participants A total of 94 abortion facilities were identified. Main outcome measures The number and location of services were compared with the distribution of reproductive-age women by location of residence. Results We identified 94 Canadian facilities providing abortion in 2012, with 48.9% in Quebec. The response rate was 83.0% (78 of 94). Facilities in every jurisdiction with services responded. In Quebec and British Columbia abortion services are nearly equally present in large urban centres and rural locations throughout the provinces; in other Canadian provinces services are chiefly located in large urban areas. No abortion services were identified in Prince Edward Island. Respondents reported provision of 75 650 abortions in 2012 (including 4.0% by medical abortion). Canadian facilities reported minimal or no harassment, in stark contrast to American facilities that responded to the same survey. Conclusion Access to abortion services varies by region across Canada. Services are not equitably distributed in relation to the regions where reproductive-age women reside. British Columbia and Quebec have demonstrated effective strategies to address disparities. Health policy and service improvements have the potential to address current abortion access inequity in Canada. These measures include improved access to mifepristone for medical abortion; provincial policies to support abortion services; routine abortion training within family medicine residency programs; and increasing the scope of practice for nurses and midwives to include abortion

  3. Landfill gas management in Canada

    International Nuclear Information System (INIS)

    Landfill gas produced from solid waste landfills is one of the most significant sources of anthropogenic methane in Canada. Methane, a potent greenhouse gas, is 24.5 times more powerful than carbon dioxide by weight in terms of global climate change. Landfill gas recovery plays an important role in Canada's commitment to stabilize greenhouse gas emissions at 1990 levels by the year 2000 under the United Nations Framework Convention on Climate Change. Landfill gas is a potentially harmful emission that can be converted into a reliable environmentally-sustainable energy source used to generate electricity, fuel industries and heat buildings. The recovery and utilization of landfill gas is a win-win situation which makes good sense from local, regional and global perspectives. It provides the benefits of (1) reducing the release of greenhouse gases that contribute to global warming; (2) limiting odors; (3) controlling damage to vegetation; (4) reducing risks from explosions, fires and asphyxiation; (5) converting a harmful emission into a reliable energy source; and (6) creating a potential source of revenue and profit. Canadian landfills generate about 1 million tons of methane every year; the equivalent energy of 9 million barrels of oil (eight oil super tankers), or enough energy to meet the annual heating needs of more than half a million Canadian homes. Currently, twenty-seven facilities recover and combust roughly 25% of the methane generated by Canadian landfills producing about 3.2 PJ (1015 Joules) of energy including 80 MW of electricity and direct fuel for nearby facilities (e.g., cement plants, gypsum board manufacturers, recycling facilities, greenhouses). This paper reviews landfill gas characteristics; environmental, health and safety impacts; landfill gas management in Canada; the costs of landfill gas recovery and utilization systems; and on-going projects on landfill gas utilization and flaring

  4. Nuclear waste management in Canada

    International Nuclear Information System (INIS)

    The classification of radioactive wastes in Canada involves two categories - waste of such a nature or in such amounts that it could be hazardous to the public, and waste which can be dealt with safely by methods available to individual institutions having at their disposal only conventional methods for getting rid of unwanted material. It is easy to provide for long-term retention of radioactive wastes if no account need be taken of expense. However, it is unreasonable (and discouraging to progress) to insist upon techniques of waste management that are applicable to multi-curie sources when the amounts to be dealt with are in the millicurie range.

  5. Decommissioning Experience: Chalk River, Canada

    International Nuclear Information System (INIS)

    Full text: Atomic Energy of Canada Limited has reported that work has continued on the decommissioning of old structures on the Chalk River laboratory site. An environmental assessment was approved in 2006 for the decommissioning of the NRX reactor fuel bays (A and B). The regulator approved two work packages for the removal of water and the wooden structure over the bays. The A bays were cleaned as far as possible and were emptied in 2007. Decontamination work will continue. Sections of the B bays were filled with sand and other parts filled with water. NRX is currently in storage (i.e. a dormant state) with surveillance. (author)

    Full Text Available We describe a multiscale modeling hierarchy for the particular case of Au-island ripening on Au(100. Starting at the microscopic scale, density functional theory was used to investigate a limited number of self-diffusion processes on perfect and imperfect Au(100 surfaces. The obtained structural and energetic information served as basis for optimizing a reactive forcefield (here ReaxFF, which afterwards was used to address the mesoscopic scale. Reactive force field simulations were performed to investigate more diffusion possibilities at a lower computational cost but with similar accuracy. Finally, we reached the macroscale by means of kinetic Monte Carlo (kMC simulations. The reaction rates for the reaction process database used in the kMC simulations were generated using the reactive force field. Using this strategy, we simulated nucleation, aggregation, and fluctuation processes for monoatomic high islands on Au(100 and modeled their equilibrium shape structures. Finally, by calculating the step line tension at different temperatures, we were able to make a direct comparison with available experimental data.

  12. Natural background radiation in Canada

    International Nuclear Information System (INIS)

    Published airborne gamma ray survey data from 33 areas of Canada were used to compile information on the average ground level exposure from natural radiation. The exposures at ground level were calculated from the surface concentrations of potassium, uranium and thorium. The highest levels of radioactivity were found in northern Canada and were generally related to granitic rocks; the lowest levels with the Athabasca sandstone. Summer outdoor exposure rates have a population-weighted average of 3.7 +- 2.3 μR.h-1, of which 48 percent orginated from potassium, 43 percent from the thorium series and 9 percent from the uranium series. This low level of radioactivity, compared to worldwide data, has resulted from erosion of a geologically old continental crust in which radioactivity decreases with depth. When seasonal variations of soil moisture and snow cover are considered, the annual population-weighted average outdoor exposure rate decreases to 2.8 +- 1.7 μR.h-1 corresponding to an annual outdoor dose-equivalent of 150 +- 90 μSV. Factors increasing the annual outdoor dose-equivalent are cosmic radiation (320 +- 30 μSV) and the internal radioactivity of the body (190 μSV). Using the ratio between indoor and outdoor values for worldwide published data, the average annual Canadian whole-body dose-equivalent from all sources of natural radiation is estimated to be 690 +-130 μSV

  13. 2000 Western Canada activity forecast

    International Nuclear Information System (INIS)

    All wells drilled in Western Canada during the first nine months of 1999 are listed and sorted into 12 geographical areas used in the Petroleum Services Association of Canada (PSAC) well cost study. Each area represents wells of common drilling, production and depth characteristics. Area totals for well counts and meters drilled were determined from the sorting process. Previous years' activities are reviewed and various operators and PSAC members contacted to review upcoming programs. In addition, trends and other projections were consulted to develop an estimate of drilling activity for the rest of 1999 as well as a projection of drilling activity for 2000. The historical and projected drilling activities were tabulated and plotted for each area. Average drilling costs for each area were determined, and the total expenditures were calculated for each area by multiplying the the projected meterage by the adjusted drilling costs. All costs were allocated to various services and products utilizing percentages determined in the Well Cost Study. During the sorting process, a list was developed of the major operators in each area, which list is included in the report along with average depths and types of wells drilled by the various operators in each area. The costs included in the report include only drilling and completion operations, starting with the building of the location prior to drilling, and ending with the installation of the wellhead after construction. 5 tabs

  14. 1999 Western Canada activity forecast

    International Nuclear Information System (INIS)

    The forecasts contained in this report are based on a review of the drilling activity through the first eight months of 1998 in twelve geographic areas of Western Canada. The forecasts incorporate current operator activity and trends into an estimate of well counts and meters drilled for the entire year of 1998. The estimates produced in this manner serve as the basis for the activity forecast for 1999. This projection, and cost data developed for the Association's 1998 Well Cost Study released in September 1998, provide the foundation for calculating the anticipated expenditure for various products and services in each of the specified geographical areas. Major operators in each area, and the type of drilling activities conducted by them, are also included. For Western Canada as a whole, a total of 9,885 wells are predicted to be drilled in 1999, at a total expenditure of $3.939 billion. The predicted average well depth will be 1,171 m, at an average cost of $ 219/m

  15. Nuclear emergency preparedness in Canada

    International Nuclear Information System (INIS)

    The preparedness of utilities and government agencies at various levels for dealing with nuclear emergencies occurring at nuclear reactors in Canada is reviewed and assessed. The review is centered on power reactors, but selected research reactors are included also. Emergency planning in the U.S.A., Germany and France, and international recommendations on emergency planning are reviewed to provide background and a basis for comparison. The findings are that Canadians are generally well protected by existing nuclear emergency plans at the electric utility and provincial levels but there are improvements that can be made, mainly at the federal level and in federal-provincial coordination. Ten issues of importance are identified: commitment to nuclear emergency planning by the federal government; division of federal and provincial roles and responsibilities; auditing of nuclear emergency preparedness of all levels of government and of electric utilities; the availability of technical guidance appropriate to Canada; protective action levels for public health and safety; communication with the public; planning and response for the later phases of a nuclear emergency; off-site exercises and training; coordination of international assistance; and emergency planning for research reactors.

  16. Eastern Canada natural gas developments

    International Nuclear Information System (INIS)

    This power point presentation addressed the following topics regarding development of natural gas in eastern Canada: (1) the 18 Tcf of proven natural gas reserves at Sable Island, (2) Canadian markets benefiting from the Maritimes and Northeast Pipeline (M and NP), (3) a 20 year franchise agreement between Enbridge Gas and the government of New Brunswick, (4) the 25 year provincial franchise agreement by Sempra Atlantic Gas, and (5) Sable Island's influence on central Canada. The Sable Offshore Energy Project (SOEP) is now producing about 540,000 MMBtu/day from 6 fields. Plans for Tier 2 expansion are underway. Firm contracts for the M and NP are scheduled to transport gas from the SOEP to markets in Nova Scotia, New Brunswick, Maine and New Hampshire. Sable gas is also a potential supply for the Quebec market. Gaz Metropolitain and Enbridge have proposed to build the Cartier Pipeline from the Quebec/New Brunswick border to Quebec City. It is unlikely that Sable Island supply will directly serve the Ontario market. Canadian customers for Sable gas and M and NP service include pulp and paper companies, oil refineries, power generators and local distribution companies (LDC), with the majority of demand coming form the electric power industry. tabs., figs

  17. Energy in Canada: An overview

    International Nuclear Information System (INIS)

    Recent changes in the North American natural gas industry are discussed, with a focus on how these changes will affect the ability of Alberta and Canadian natural gas supply to meet market growth. These changes include a decline in the merchant role of many of the major interstate pipelines, resulting in a larger number of smaller-sized purchasers for natural gas marketers to deal with; a greater extent of direct purchasing by local distribution companies and large industrial users, combined with a preference for spot sales rather than long-term commitments; direct marketing of uncontracted gas by many producers and brokers; a bidding type of sales process rather than a negotiated process; and price deregulation. It is foreseen that long term security of supply will again become an important factor to North American buyers, and Canada can offer substantial supplies under secure long term contracts. Marketers will have to seek new market targets such as cogeneration plants and the transportation sector. Access to pipeline transport will be one of the major factors in obtaining new markets. The Canada-USA free trade agreement is viewed as a positive development which should help Canadian gas marketers to gain and retain U.S. customers

    The present work proposes a theoretical method called ionization dynamics to derive the ionic charge state distribution. Using relativistic quantum mechanics to calculate the energy level lifetime and average ionic lifetime of each ion, the first-order ionization rate constant can be obtained. Based on these data, from the solution of differential equations for consecutive-irreversible ionization reactions, one will be able to derive the ionic charge state distribution.The calculated average positive charge 49.24 of Au48+ ~ Au52+ and their relative distribution are in good agreement with the results of Lawrence Livermore National Laboratory.

  2. Canada's forest biomass resources: deriving estimates from Canada's forest inventory

    International Nuclear Information System (INIS)

    A biomass inventory for Canada was undertaken to address the data needs of carbon budget modelers, specifically to provide estimates of above-ground tree components and of non-merchantable trees in Canadian forests. The objective was to produce a national method for converting volume estimates to biomass that was standardized, repeatable across the country, efficient and well documented. Different conversion methods were used for low productivity forests (productivity class 1) and higher productivity forests (productivity class 2). The conversion factors were computed by constructing hypothetical stands for each site, age, species and province combination, and estimating the merchantable volume and all the above-ground biomass components from suitable published equations. This report documents the procedures for deriving the national biomass inventory, and provides illustrative examples of the results. 46 refs., 9 tabs., 5 figs

  9. Restricted Access to Justice for Canadians Mistreated Abroad: Abdelrazik v Canada (Re: Interim Costs

    Directory of Open Access Journals (Sweden)

    Sean Rehaag

    2015-12-01

    In Abdelrazik v Canada, the Federal Court denied the request for interim costs – a decision that has serious implications not only for interim cost awards jurisprudence, but also for litigation involving citizens who allege that their rights under section 6 of the Charter have been violated. This comment critically analyzes the access to justice implications of the Federal Court decision in light of both the principle that courts may use costs awards to promote access to justice, and the unique challenges faced by Canadians mistreated abroad by the Canadian government. Abousfian Abdelrazik est ce citoyen canadien dont le nom avait été ajouté à diverses listes de personnes soupçonnées de terrorisme, qui avait été torturé par les autorités soudanaises et qui a appris qu’il ne pouvait pas revenir au Canada principalement en raison des mesures que le gouvernement du Canada avait prises. Abdelrazik souhaitait contester la constitutionnalité des limites à sa capacité de rentrer au Canada. Toutefois, il n’avait pas d’argent ni aucun moyen de subsistance puisqu’il ne pouvait pas quitter l’ambassade du Canada au Soudan, où il s’était réfugié pour éviter d’être torturé de nouveau par les autorités soudanaises. Il a donc déposé une requête en vue d’obtenir une provision pour les frais devant la Cour fédérale du Canada. Si sa requête avait été accueillie, le gouvernement du Canada aurait été tenu de payer ses honoraires d’avocats, et le tribunal aurait entendu sa contestation de la constitutionnalité des mesures que le Canada avait prises. Dans Abdelrazik v Canada, la Cour fédérale a rejeté la requête. Cette décision aura de graves répercussions non seulement sur la jurisprudence relative aux requêtes en vue d’obtenir une provision pour les frais, mais également sur les instances mettant en cause des citoyens qui allèguent qu’il y a eu violation des droits qui leur sont garantis par l’article 6 de la Charte

  10. Biosynthesis and stabilization of Au and Au-Ag alloy nanoparticles by fungus, Fusarium semitectum

    International Nuclear Information System (INIS)

    Crystallized and spherical-shaped Au and Au-Ag alloy nanoparticles have been synthesized and stabilized using a fungus, F . semitectum in an aqueous system. Aqueous solutions of chloroaurate ions for Au and chloroaurate and Ag+ ions (1 : 1 ratio) for Au-Ag alloy were treated with an extracellular filtrate of F . semitectum biomass for the formation of Au nanoparticles (AuNP) and Au-Ag alloy nanoparticles (Au-AgNP). Analysis of the feasibility of the biosynthesized nanoparticles and core-shell alloy nanoparticles from fungal strains is particularly significant. The resultant colloidal suspensions are highly stable for many weeks. The obtained Au and Au-Ag alloy nanoparticles were characterized by the surface plasmon resonance (SPR) peaks using a UV-vis spectrophotometer, and the structure, morphology and size were determined by Fourier transform infrared spectroscopy (FTIR), x-ray diffraction (XRD), and transmission electron microscopy (TEM). Possible optoelectronics and medical applications of these nanoparticles are envisaged.

    1997-01-01

    Using the FOPI detector at GSI Darmstadt, excitation functions of collective flow components were measured for the Au+Au system, in the reaction plane and out of this plane, at seven incident energies ranging from 100AMeV to 800AMeV. The threshold energies, corresponding to the onset of sideward-flow (balance energy) and squeeze-out effect (transition energy), are extracted from extrapolations of these excitation functions toward lower beam energies for charged products with Z>2. The transition energy is found to be larger than the balance energy. The impact parameter dependence of both balance and transition energies, when extrapolated to central collisions, suggests comparable although slightly higher values than the threshold energy for the radial flow. The relevant parameter seems to be the energy deposited into the system in order to overcome the attractive nuclear forces.

  12. Nuclear Modification of Jet Fragmentation in Au+Au Collisions

    Rowan, Zachary; Phenix Collaboration

    2015-10-01

    The characterization of energy in the quark gluon plasma is facilitated by measurements of modifications to the observed jet fragmentation. A favorable channel of study relies on direct photons created in the initial parton interactions of heavy ion collisions. Such a photon traverses the created medium unscathed and grants us a proxy for the transverse momentum of an away side jet. PHENIX Au+Au data recorded at √{sNN} = 200 GeV during RHIC run 14 benefit from the background rejection capability of the silicon vertex detector, enabling the extraction of a higher purity hadron signal. This advantage, combined with a larger integrated luminosity, allows previous PHENIX measurements of fragmentation functions to be extended to greater jet energies. In this talk, the status of the analysis of direct photon hadron correlations with the new data set will be discussed.

    The system created in non-central relativistic nucleus-nucleus collisions possesses large orbital angular momentum. Due to spin-orbit coupling, particles produced in such a system could become globally polarized along the direction of the system angular momentum. We present the results of Lambda and anti-Lambda hyperon global polarization measurements in Au+Au collisions at sqrt{s_NN}=62.4 GeV and 200 GeV performed with the STAR detector at RHIC. The observed global polarization of Lambda and anti-Lambda hyperons in the STAR acceptance is consistent with zero within the precision of the measurements. The obtained upper limit, |P_{Lambda,anti-Lambda}| <= 0.02, is compared to the theoretical values discussed recently in the literature.

    Although neat gold-thiolate oligomers and polymers made of linear S-Au-S bonds have been well-known, observation of RS-Au-SR linear complexes (RS-being an alkylthiolate group) on Au(111) has been reported only recently. On the basis of the unique geometry and bonding of the RS-Au-SR complex on Au(111), we construct simple geometric models of Au-SR oligomers and polymers on Au(111) by fusing linear S-Au-S units matched to the underlying Au(111) surface lattice. We then optimize these models by density functional theory. The hexagonal geometry of the Au(111) lattice determines three possible angles (60{sup o}, 120{sup o}, and 180{sup o}) for connecting two linear S-Au-S units, which lead to isomerism of the Au-SR oligomers and polymer on Au(111). Here we explore open dimers, trimers, and tetramers and cyclic trimers, tetramers, and hexamers of the Au-SR oligomers on Au(111). We also examine four isomers of the Au-SR polymer on Au(111). We find that the 120{sup o} Au-S-Au angle is preferred in constructing both oligomeric and polymeric isomers. The two polymeric isomers with 120{sup o} Au-S-Au angles are found to be energetically competitive with a previous model proposed for the Au-SR polymer on Au(111). We also discuss potential ways to create Au-SR oligomers on Au(111).

    Bernanke [Bernanke, Ben S. Irreversibility, uncertainty, and cyclical investment. Quarterly Journal of Economics 98 (1983), 85-106.] shows how uncertainty about energy prices may induce optimizing firms to postpone investment decisions, thereby leading to a decline in aggregate output. Elder and Serletis [Elder, John and Serletis, Apostolos. Oil price uncertainty.] find empirical evidence that uncertainty about oil prices has tended to depress investment in the United States. In this paper we assess the robustness of these results by investigating the effects of oil price uncertainty in Canada. Our results are remarkably similar to existing results for the United States, providing additional evidence that uncertainty about oil prices may provide another explanation for why the sharp oil price declines of 1985 failed to produce rapid output growth. Impulse-response analysis suggests that uncertainty about oil prices may tend to reinforce the negative response of output to positive oil shocks. (author)

  18. 1999 Western Canada activity forecast

    International Nuclear Information System (INIS)

    Oil and gas drilling activity for the final quarter of 1998 and the first quarter of 1999 for 12 specific geographical areas in Western Canada is reviewed. Each area represents wells of common drilling, production and depth characteristics. Current operator activity and trends are incorporated into an estimate of well counts for 1999. Average drilling costs for each area are also calculated. Drilling of about 8920 wells is projected for 1999. The anticipated drilling and completion expenditures will be about $3.2 (Cdn) billion. While horizontal drilling activity appears to have decreased slightly in 1998, an increase to over 1200 horizontal and directionally drilled wells is projected for 1999. A list of the major operators in each geographical area is also provided. 8 tabs., 3 figs

  20. Environmental radioactivity in Canada 1988

    International Nuclear Information System (INIS)

    The radiological surveillance program of the Department of National Health and Welfare is conducted for the purpose of determining levels of environmental radioactivity in Canada and assessing the resulting population exposures. Following major changes to the CAMECO Port Hope operations to reduce uranium emissions, a study was initiated to measure uranium levels in air in the community. Studies continued on lung cancer and domestic exposure to radon, and current levels of cesium-137 in caribou, a major source of food in northern communities. The movement of tritium on the Ottawa and St. Lawrence rivers was studied following an accidental release into the Ottawa River. Monitoring continued of fallout contamination from Chernobyl in imported foods. All measurements recorded during 1988 were below the limits recommended by the International Commission on Radiological Protection. (14 refs., 14 figs., 15 tabs.)

  1. Beyond design basis in Canada

    International Nuclear Information System (INIS)

    In response to the Fukushima Daiichi accident, the Canadian Government required: — Ongoing environmental monitoring on Canadian territory from coast to coast. — Deployment of experts to the IAEA. —Issuance of a directive pursuant to the regulatory requirements to all major nuclear facilities to review initial lessons learned. — Re-examination of the safety cases with a focus on: ● External hazards and measures to prevent or mitigate severe accidents; ● Emergency preparedness; ● Implementation of immediate short term and long term measures. At the regulatory level, the CNSC carried out reviews of the safety status of the plants in Canada and abroad. The CNSC site staff carried out focused inspection on seismic, fire, flooding, backup power, hydrogen igniters and passive recombiners, in addition to ongoing inspections against external hazards. The CNSC conducted inspections of spent fuel bays, their components and equipment, heat sinks and alarms, as well as the availability of on-site and off-site resources

  2. d + Au hadron correlation measurements at PHENIX

    In these proceedings, we discuss recent results from d + Au collisions in PHENIX ridge related measurements and their possible hydrodynamic origin. We present the v2 at midrapidity and measurements of the pseudorapidity dependence of the ridge, distinguishing between the d-going and Au-going directions. We investigate the possible geometrical origin by comparing v2 in d + Au to that in p + Pb, Au + Au and Pb + Pb collisions. Future plans to clarify the role of geometry in small collision systems at RHIC are discussed

    Le trickster est un personnage légendaire, présent dans toutes les cultures autochtones d’Amérique du Nord. C’est l’anthropologue Paul Radin qui, en 1956, a décrit et analysé pour la première fois le mythe complet du trickster chez les Winnebagos. Chez ces derniers, le trickster a pour nom Wakdjunkaga, ce qui signifie littéralement « celui-qui-joue-des-tours ». La particularité du trickster est en effet de ne jamais être là où on l’attend, d’être insaisissable. C’est pour cette raison que dur...

  6. Decay spectroscopy of $^{178}$Au

    CERN Document Server

    Whitmore, B

    In this thesis, the neutron-deficient nucleus $^{178}$Au is investigated through decay spectroscopy. Si and HPGe detectors were used to analyse the decay radiation of $^{178}$Au and its daughter nuclei. Previous studies have been unable to distinguish decay radiation from different isomeric states of this nucleus. This thesis represents the first time such isomeric discrimination has been achieved, and presents tentative spin assignments of both the ground state and an isomer. The neutron-deficient gold isotopes are an area of interest for the study of shape coexistence. This is the phenomenon exhibited by nuclei able to exist at a number of close lying energy minima, each reflecting a distinct type of deformation. It is hoped that studies such as this can help identify the evolution of nuclear deformation in this region of the nuclear chart.

    Full Text Available AbstractThis study revisited the “double jeopardy” hypothesis in terms of the health ofimmigrant family caregivers. It also investigated the effect of “reciprocity”(feeling of giving back something on the health of family caregivers. TheGeneral Social Survey 2002 Cycle 16 data were analyzed using χ2-test andLogistic regressions. About 16% of immigrants and 13.6% of non-immigrantssaid that their health was negatively affected as a result of caregiving.Immigrant family caregivers were three times more likely than non-immigrantsto report a health consequence. Reciprocity played a big role in this outcome.Given the fact that an increasing number of culturally diverse immigrants enterCanada every year and that the immigrant population is aging, more caregiverswill be in demand. Policy makers need to find ways to keep immigrantcaregivers healthy so that quality care can be given to immigrant older adultsand also for maintaining an overall healthy Canada.RésuméCette étude réexamine l'hypothèse de «non bis in idem» dans le contexte de lasanté des aidantes et aidants membres de familles immigrantes.

    Canada's non-proliferation and safeguards policy has two objectives: 1) to promote the emergence of a more effective and comprehensive international non-proliferation regime; and 2) to assure the Canadian people and the international community that Canadian nuclear exports will not be used for any nuclear explosive purpose. By emphasizing the key role of the NPT, by promoting reliance upon and improvements in the IAEA safeguards system, by treating nuclear weapon and non-nuclear weapon states alike regarding Canadian nuclear exports, by working for new approaches covering the sensitive phases (e.g. reprocessing) of the nuclear fuel cycle, Canada's policy promotes attainment of the first objective. The latter objective is served through the network of bilateral nuclear agreements that Canada has put into place with its nuclear partners. Those agreements provide assurance that Canada's nuclear exports are used solely for legitimate, peaceful, nuclear energy production purposes. At the same time, Canada, having formulated its non-proliferation and safeguards policy during the period 1945 to 1980, has recognized that it has gone as far as it can on its own in this field and that from this point on any further changes should be made on the basis of international agreement. The Canadian objective in post-INFCE forums such as the Committee on Assurances of Supply is to exert Canada's best efforts to persuade the international community to devise a more effective and comprehensive international non-proliferation regime into which Canada and other suppliers might subsume their national requirements

  9. Uranium in Canada: Billion-dollar industry

    International Nuclear Information System (INIS)

    In 1988, Canada maintained its position as the world's leading producer and exporter of uranium; five primary uranium producers reported concentrate output containing 12,400 MT of uranium, or about one-third of Western production. Uranium shipments made by these producers in 1988 exceeded 13,200 MT, worth Canadian $1.1 billion. Because domestic requirements represent only 15% of current Canadian output, most of Canada's uranium production is available for export. Despite continued market uncertainty in 1988, Canada's uranium producers signed new sales contracts for some 14,000 MT, twice the 1987 level. About 90% of this new volume is with the US, now Canada's major uranium customer. The recent implementation of the Canada/US Free Trade agreement brings benefits to both countries; the uranium industries in each can now develop in an orderly, free market. Canada's uranium industry was restructured and consolidated in 1988 through merger and acquisition; three new uranium projects advanced significantly. Canada's new policy on nonresident ownership in the uranium mining sector, designed to encourage both Canadian and foreign investment, should greatly improve efforts to finance the development of recent Canadian uranium discoveries

  10. Taxi and limousine industry in Canada

    International Nuclear Information System (INIS)

    Taxi and limousine service plays an important role in the movement of people within a city. In 2004, the total revenue in this industry in Canada was $1.305 billion, and an estimated 35,339 carriers served the industry. In Canada, economic and safety regulations of taxi supply were imposed in most cities during the 1930s and 1940s and continue to this date. Although the industry is regulated, the competition law also applies. The appropriateness of these regulations continues to be challenged and regulatory reforms in the major cities in Canada have concentrated their efforts on increasing the rate of services, improving the quality of vehicles and enhancing the training of taxi drivers. Indicators for the 1999-2004 period reveal that the taxi and limousine industry in Canada did not perform very well. Revenue increased by only 1.7 per cent per year and margins deteriorated by -1.78 per cent together with the operating ratio. The purpose of this paper was to examine the taxi and limousine industry in Canada. First, the structure of the industry in Canada was examined followed by a review of the economic regulation of the industry. Recent regulatory developments in Canada and in other countries were then reviewed with arguments for or against deregulation. 28 refs., 2 tabs

  11. Petro-Canada 1997 annual report

    International Nuclear Information System (INIS)

    Petro-Canada is a dominant player in the petroleum industry in Western Canada as well as on the Grand Banks offshore Newfoundland. This report presents a review of operations, provides detailed statements of the corporation's finances, and a wealth of information of interest to shareholders. The report states that in 1997 Petro-Canada achieved record financial results, following a dramatic turnaround over the past five years. Net earnings for 1997 were $306 million, a $59 million increase over 1996. The company's share price appreciated 34 per cent in 1997 and was one of the most heavily traded stocks in Canada. The company plans to maximize shareholder value by reducing its interests in conventional oil from mature fields in western Canada and by re-investing the proceeds in natural gas development. Petro-Canada is also committed to an expansion that will double production at the Syncrude oil sands plant over the next decade and has tested large in-situ oil sands resources for potential development in northeastern Alberta. On the Atlantic coast too, Petro-Canada is delivering leadership with increasing production from Hibernia, and final approvals in place to proceed with development of the Terra Nova field. International operations are also contributing to the Corporation's profitability by delivering new production from oil fields offshore Norway and from the Sahara Desert in North Africa. tabs., figs

  15. Fabricating a Homogeneously Alloyed AuAg Shell on Au Nanorods to Achieve Strong, Stable, and Tunable Surface Plasmon Resonances

    KAUST Repository

    Huang, Jianfeng

    2015-08-13

    Colloidal metal nanocrystals with strong, stable, and tunable localized surface plasmon resonances (SPRs) can be useful in a corrosive environment for many applications including field-enhanced spectroscopies, plasmon-mediated catalysis, etc. Here, a new synthetic strategy is reported that enables the epitaxial growth of a homogeneously alloyed AuAg shell on Au nanorod seeds, circumventing the phase segregation of Au and Ag encountered in conventional synthesis. The resulting core–shell structured bimetallic nanorods (AuNR@AuAg) have well-mixed Au and Ag atoms in their shell without discernible domains. This degree of mixing allows AuNR@AuAg to combine the high stability of Au with the superior plasmonic activity of Ag, thus outperforming seemingly similar nanostructures with monometallic shells (e.g., Ag-coated Au NRs (AuNR@Ag) and Au-coated Au NRs (AuNR@Au)). AuNR@AuAg is comparable to AuNR@Ag in plasmonic activity, but that it is markedly more stable toward oxidative treatment. Specifically, AuNR@AuAg and AuNR@Ag exhibit similarly strong signals in surface-enhanced Raman spectroscopy that are some 30-fold higher than that of AuNR@Au. When incubated with a H2O2 solution (0.5 m), the plasmonic activity of AuNR@Ag immediately and severely decayed, whereas AuNR@AuAg retained its activity intact. Moreover, the longitudinal SPR frequency of AuNR@AuAg can be tuned throughout the red wavelengths (≈620–690 nm) by controlling the thickness of the AuAg alloy shell. The synthetic strategy is versatile to fabricate AuAg alloyed shells on different shaped Au, with prospects for new possibilities in the synthesis and application of plasmonic nanocrystals.

    We report a 63-year-old lady with Cronkhite-Canada syndrome, who developed colorectal cancer. A hemicolectomy was performed, and the tumor specimen was prepared for DNA-analysis and immunohistochemical screening. We found a mutation of p53 gene without APC- and ras-gene alteration and expression of erbB2-protooncogen. The polyps in non-hereditary Cronkhite-Canada-syndrom are neither adenomatous nor hyperplastic, but patients often develop colorectal cancers. The steps of mutation do not follow the adenoma-carcinoma sequence, first described by Vogelstein 1988. This and previous observations suggest that carcinogenesis in Cronkhite-Canada syndrome follows another independent sequence. PMID:11413916

  11. Canada's nuclear non-proliferation policy

    International Nuclear Information System (INIS)

    Canada's non-proliferation safeguards policy has two objectives: 1) to promote a more effective and comprehensive international non-proliferation regime; and 2) to ensure that Canadian nuclear exports will not be used for any nuclear explosive purpose. By emphasizing the key role of the Non-Proliferation Treaty, promoting reliance upon and improvements in the IAEA safeguards system, treating nuclear weapon and non-weapon states alike, and working for new approaches covering reprocessing, Canada promotes attainment of the first objective. The second is served through the network of bilateral nuclear agreements that Canada has put into place with its partners. The Canadian objective in post-INFCE forums is to persuade the international community to devise a more effective and comprehensive non-proliferation regime into which Canada and other suppliers may subsume their national requirements

  12. Emerging Churches in Post-Christian Canada

    Directory of Open Access Journals (Sweden)

    2012-09-01

    Full Text Available The traditional mainline and evangelical churches in Canada, as in most western countries, are either in decline or static. Taken as a measure of the future, the prospects for Christianity in Canada, and more broadly the West, are bleak. Post-Christian Canada, however, contains thriving alternative and innovative forms of church, often called ‘emerging’ churches. They take many forms of expression, but share common theological convictions. Based on site research and personal interviews, this article describes the various types and contexts of these churches in Canada. It then highlights three of their central theological characteristics. First, rejecting the ‘culture wars’ social involvement of Christendom churches, they embrace practices and initiatives that transform their local communities. Second, they embrace an incarnational and contextual understanding of Christian life and ministry. Eschewing mega-church franchise models, they endeavor to shape their ministry to the their local communities. Third, they adopt a comprehensive rather than compartmental spirituality.

  14. Canada's constitutional separation of (wind) power

    International Nuclear Information System (INIS)

    This paper investigates the impact that a federal government structure has on strategic selection of renewable energy policy instruments. The context for this study centers on wind power development in Canada. Canada is a nation that is blessed by all the attributes necessary to catalyze global leadership in installed wind power capacity. Unfortunately, the constitutional separation of powers that underpins Canada's federal system impedes the creation of a national wind power development strategy because Canada's provinces have constitutional authority over electricity governance. The insights gleaned from the case study are used to develop a conceptual framework for understanding the impact that federal structure has on policy instrument selection and efficacy under areas of federal, regional and concurrent policy jurisdiction. Finally, this framework is re-applied to identify specific approaches the Canadian federal government could take to resolve what currently amounts to be a fragmented, ineffective approach to wind power development planning.

The changes in the new version of the Plan are the result of continued consultations with industry and the provinces. The revised Plan addresses nine of the 12 concerns expressed by the provinces. Key changes include: (1) establishment of sectoral emissions reduction targets through negotiated covenants with a regulatory or financial backstop; (2) guaranteeing a limit of 55 Megatonnes reductions for covered sectors under the covenants and trading system; (3) introducing flexibility in timing by signaling willingness on the part of the Government to discuss acceptance of commitments over a longer term; (4) promising to work with industry on options for providing protection against risks associated with sustained carbon prices above certain levels; (5) designing implementation system in such a way as to not disadvantage those companies that have taken early action in emission reductions; (6) building in contingencies, assessing progress and adjusting the Federal approach and level of investment; (7) remaining engaged in joint efforts with the United States to minimize impacts on Canadian competitiveness. The Federal Government also recognizes the need for further research in addressing climate model uncertainties, in providing regional-scale climate change information, in future evolution of the climate in the Arctic, and in determining the record of past climate variability and extremes

    International Nuclear Information System (INIS)

    After three years of evaluating prospects and negotiating with government and industry representatives, Gulf Canada established its first joint venture in the Russian Federation with Komineft, a production association from the Komi autonomous republic. Komineft has a 50% share of the venture, and the rest is shared equally between Gulf and British Gas. The operating area is at the Vozey and Upper Vozey fields in the Timan-Pechora Basin, some 1,500 km northeast of Moscow just inside the Arctic Circle. An attractive feature of the Upper Vozey project is low development costs of ca $2/bbl. In the Vozey field, the venture will set up an enhanced oil recovery demonstration project to test techniques perfected in Alberta. About 60 Canadians are involved on the project, and headquarters are in Usinsk, ca 100 km south of the oil fields. In the first half of 1992, oil production in the first phase of the venture averaged around 10,000 bbl/d and continues to increase

  19. Understanding gasoline pricing in Canada

    International Nuclear Information System (INIS)

    This brochure is designed to help consumers understand how gasoline is priced and explained why prices increase, fluctuate and vary by location, city or region. The price of a litre of gasoline reflects the costs of crude oil, refining, retailing and taxes. Taxes are usually the largest single component of gasoline prices, averaging 40 to 50 per cent of the pump price. The cost of crude oil makes up another 35 to 45 per cent of the price. Refining costs make up 10 to 15 per cent while the remaining 5 to 10 per cent represents retail costs. Gasoline retailers make a profit of about 1 cent per litre. The latest network technology allows national and regional retail chains to constantly monitor price fluctuations to change their prices at gasoline stations at a moments notice to keep up with the competition and to protect their market shares. Several government studies, plus the Conference Board of Canada, have reported that competition is working in favour of Canadian motorists. This brochure also explained the drawbacks of regulating crude and pump prices with the reminder that crude prices were regulated in the 1970s with many negative consequences. 2 tabs., 1 fig

  6. Increasing turbine vendor competition in Canada

    International Nuclear Information System (INIS)

    An overview of the wind turbine market in Canada was presented. Canada is now experiencing increased turbine vendor competition. Trends in wind turbine OEM market shares in Canada have increased from 10 per cent in 2000 to over 70 per cent in 2007. Several major companies in Canada have signed large-scale orders for delivery in 2010. It is expected that future wind turbine demands in all areas of Canada will increase. However, projections for Canadian wind growth demonstrate the difficulties provinces are now facing in trying to attract manufacturing investment away from the United States. Growth in wind turbine investment is in the process of creating a more robust North American wind turbine generator chain. However, the majority of new facilities are located in the United States. It is not known if Quebec's wind turbine generators will be viable outside of fulfilling Hydro-Quebec's tendering process. Canada's wind industry must consider equipment transport costs as well as a shortage of operating and maintenance service infrastructure. It was concluded that growth in the United States is expected to have a positive impact on Canadian wind energy customers. tabs., figs

  7. Cultural influence, economic security, and the fertility behavior of the Chinese in Canada

    Directory of Open Access Journals (Sweden)

    Tang, Zongli

    2001-01-01

    Full Text Available EnglishThis study explores interactions of cultural influence and economic insecurity and their effects on the fertility behavior of the Chinese in Canada. The importance of group context on the actions of individuals is measured through data from the PUST of the 1971 and1991 Canadian Censuses. Contextual analysis and random coefficient models are the major statistical tools employed to achieve the above objectives. The Chinese-Canadians are compared to the British-Canadians, who are used as the reference group. The findings suggest that Chinese reproductive norms with pronatalist endowments exert strong influence on the fertility behavior of the Chinese in Canada.This influence effectively counteracts the negative effects of economic insecurity and encourages Chinese immigrants to quickly recover their fertility deficit after the initial immigration stage. The effects of the origin culture on fertility diminish with increasing exposure to the host society.However, even among the native-born or Canadian-born Chinese, the influence of Chinese reproductive norms is still present though not as strong as among the foreign-born Chinese.FrenchCette étude explore les interactions de l'influence culturelle et de l'insécuritééconomique et leurs effets sur le comportement procréateur des Chinois auCanada.

  9. RACIALIZED IN JUSTICE: THE LEGAL AND EXTRA-LEGAL STRUGGLES OF MIGRANT AGRICULTURAL WORKERS IN CANADA

    Directory of Open Access Journals (Sweden)

    Adrian A Smith

    2015-09-01

    Une attention considérable a été accordée à la décision de la Cour suprême du Canada rendue en 2011 dans l’arrêt Fraser, qui portait sur le droit constitutionnel à la liberté d’association des travailleurs agricoles en Ontario. Bien que les interventions tendent à juste titre à critiquer la décision de la Cour rejetant des droits d’association significatifs, il existe une indifférence marquée à l’égard des dimensions racialisées de la décision et de la production de la main-d’œuvre agricole au Canada d’une façon générale. Cependant, bien qu’elle soit nécessaire pour aborder les limites de l’analyse juridique savante et jurisprudentielle contemporaine, l’application des idées de la théorie raciale critique ne tient pas suffisamment compte des particularités de l’exploitation de la main-d’œuvre qui fait partie intégrante du régime canadien de migration temporaire de la main-d’œuvre. Dans le but d’approfondir l’étude de la racialisation, de la main-d’œuvre et du droit au Canada, je place les luttes judiciaires et extrajudiciaires des travailleurs agricoles migrants au sein d’une analyse antiraciste du droit qui tient compte des diverses façons dont la racialisation et le racisme influencent la migration de la main-d’œuvre. La construction du travail migrant fondée sur une catégorie racialisée -- une « nécessité structurelle » dans le cadre de la production agricole -- se fait par l’imposition d’obstacles politico-juridiques organisés par le capitalisme mondial et le système des États nationaux. L’analyse se termine en préconisant l’abandon des approches actuelles relatives à l’étude et à l’exercice du droit du travail, au profit d’un programme transgressif visant à contester ouvertement l’exploitation capitaliste sous toutes ses formes, y compris la réglementation racialisée de la main-d’œuvre agricole migrante.

    A novel interfacial route has been developed for the synthesis of a bright-red-emitting new subnanocluster, Au(23), by the core etching of a widely explored and more stable cluster, Au(25)SG(18) (in which SG is glutathione thiolate). A slight modification of this procedure results in the formation of two other known subnanoclusters, Au(22) and Au(33). Whereas Au(22) and Au(23) are water soluble and brightly fluorescent with quantum yields of 2.5 and 1.3 %, respectively, Au(33) is organic soluble and less fluorescent, with a quantum yield of 0.1 %. Au(23) exhibits quenching of fluorescence selectively in the presence of Cu(2+) ions and it can therefore be used as a metal-ion sensor. Aqueous- to organic-phase transfer of Au(23) has been carried out with fluorescence enhancement. Solvent dependency on the fluorescence of Au(23) before and after phase transfer has been studied extensively and the quantum yield of the cluster varies with the solvent used. The temperature response of Au(23) emission has been demonstrated. The inherent fluorescence of Au(23) was used for imaging human hepatoma cells by employing the avidin-biotin interaction.

  20. Initial state geometry and fluctuations in Au+Au, Cu+Au and U+U collisions at RHIC

    CERN Document Server

    Schenke, Bjoern; Venugopalan, Raju

    2014-01-01

    We study within the IP-Glasma and two-component MC-Glauber models the effects of initial state geometry and fluctuations on multiplicities and eccentricities for several collision species at the Relativistic Heavy Ion Collider (RHIC). These include copper-gold (Cu+Au), gold-gold (Au+Au), and uranium-uranium (U+U) collisions. The multiplicity densities per participant pair are very similar in all systems studied. Ellipticities vary strongly between collision systems, most significantly for central collisions, while fluctuation driven odd moments vary little between systems. Event-by-event distributions of eccentricities in mid-central collisions are wider in Cu+Au relative to Au+Au and U+U systems. An anti-correlation between multiplicity and eccentricity is observed in ultra central U+U collisions which is weaker in the IP-Glasma model than the two-component MC-Glauber model. In ultra central Au+Au collisions the two models predict opposite signs for the slope of this correlation. Measurements of elliptic flo...

  2. Opportunities in Canada's growing wind energy industry

    International Nuclear Information System (INIS)

    Investment in Canada's wind sector is projected to reach $8 billion by 2012, and growth of the sector is expected to create over 16,000 jobs. Canada's wind energy capacity grew by 54 per cent in 2005 alone, aided in part by supportive national policies and programs such as the Wind Power Production Incentive (WPPI); the Canadian Renewable Conservation Expense (CRCE) and Class 43.1 Capital Cost Allowance; and support for research and development. Major long-term commitments for clean power purchases, standard offer contracts and renewable portfolio standards in several provinces are encouraging further development of the wind energy sector. This paper argued that the development of a robust Canadian wind turbine manufacturing industry will enhance economic development, create opportunities for export; and mitigate the effects of international wind turbine supply shortages. However, it is not known whether Canadian wind turbine firms are positioned to capitalize on the sector's recent growth. While Canada imports nearly all its large wind turbine generators and components, the country has technology and manufacturing strengths in advanced power electronics and small wind systems, as well as in wind resource mapping. Wind-diesel and wind-hydrogen systems are being developed in Canada, and many of the hybrid systems will offer significant opportunities for remote communities and off-grid applications. Company partnerships for technology transfer, licensing and joint ventures will accelerate Canada's progress. A recent survey conducted by Industry Canada and the Canadian Wind Energy Association (CanWEA) indicated that the total impact of wind energy related expenditures on economic output is nearly $1.38 billion for the entire sector. Annual payroll for jobs in Canada was estimated at $50 million, and substantial employment growth in the next 5 years is expected. Canada offers a strong industrial supply base capable of manufacturing wind turbine generators and

  3. Canada vs. the OECD: an environmental comparison

    International Nuclear Information System (INIS)

    Canada's environmental performance is compared to the 28 other nations in the Organization for Economic Cooperation and Development (OECD). Twenty-five environmental indicators in ten categories are examined. These are: air, water, energy, biodiversity, waste, climate change, ozone depletion, agriculture, transportation and miscellaneous. Results show Canada with the poorest environmental record of all OECD countries, except the United States. The statistical information, compiled from data verified and published by the OECD, shows Canada among the worst three countries on nine indicators (per capita GHG emissions, CO and VOCs emissions, water consumption, energy consumption, energy efficiency, volume of timber logged, generation of nuclear waste, and the highest amount of energy consumed per unit of GDP). Tracking Canada's energy performance over the past two decades reveals that the situation is worsening in terms of water and energy consumption, production of nuclear and hazardous waste, greenhouse gas emissions, the number of endangered species, decline of fish populations, commercial fertilizer use, timber logging, number of motor vehicles, kilometres travelled by road, higher population and lower official development assistance (foreign aid). On the positive side, Canada's environmental performance was found to be poor but improving on ten indicators, including reduced air pollution, improved sewage treatment, reduced municipal waste, increased recycling, improved energy efficiency, decreased production of ozone-depleting substances and an increase in parks and protected areas

  7. Antiproton Production in Au+Au Collisions at 11.7a GeV/c

    International Nuclear Information System (INIS)

    Antiproton production in 11.7A GeV/c Au+Au collisions over a wide transverse-mass coverage was studied using the AGS-E866 experimental apparatus. The mean transverse kinetic energy increases as a function of centrality and is similar to that of protons. The antiproton yields in Si+Al , Si+Au , and Au+Au collisions are consistent with scaling with the 0.7 power of the number of participant nucleons. Copyright 1998, The American Physical Society

  10. Strain distributions of confined Au/Ag and Ag/Au nanoparticles

    2015-01-01

    The strain distributions of Au/Ag and Ag/Au nanoparticles confined in the Al2O3 matrix with different core sizes are investigated by using the finite element method, respectively. The simulation results clearly indicate that the compressive strains exerted on the Au/Ag and Ag/Au nanoparticles can be induced by the Al2O3 matrix. Moreover, it can be found that the strain gradient existing in a Au/Ag nanoparticle is much larger than that in a Ag/Au nanoparticle, which could be due to the larger Young’s modulus of Au than that of Ag. With the core size increasing, the strain gradient existing in the Au/Ag nanoparticle becomes larger, while the strain gradient existing in the Ag/Au nanoparticle keeps constant. These different strain distributions may have significant infl uences on the structures and morphologies of the Au/Ag and Ag/Au nanoparticles, leading to the different physical properties for potential applications.

    Chemically pure colloidal suspensions of gold and silver nanoparticles were synthesized using pulsed laser ablation. The dependence of laser fluence on the surface plasmon characteristics of the nanoparticles was investigated. Au:Ag colloidal suspensions were prepared by mixing highly monodisperse Au and Ag nanocolloids. The plasmon band of these mixtures was found to be highly sensitive to Au:Ag concentration ratio and wavelength of the laser beam used in the ablation process. The Au:Ag mixture consists of almost spherical shaped nanostructures with a tendency to join with adjacent ones. The surface enhanced Raman scattering activity of the Au, Ag and Au:Ag colloidal suspensions was tested using crystal violet as probe molecules. Enhancement in Raman signal obtained with Au:Ag substrates was found to be promising and strongly depends on its plasmon characteristics.

  16. Hot air : meeting Canada's climate change challenge

    International Nuclear Information System (INIS)

    As a large northern country, Canada will change significantly as a result of climate change. Global warming is expected to cause diminutions of snow and ice changes in the Arctic, as well as changes to glaciers, and the mountain snowpacks that feed rivers, and provide sources of fresh water. This book argued that the effects of global warming have been apparent in Canada for many years. Water levels in lakes and rivers have been falling, and a thawing permafrost has led to difficulties in building and maintaining winter roads in the far north. Disturbances such as the mountain pine beetle (MPB) infestation in British Columbia have also been attributed to global warming, the beetles are only killed by cold weather. The book also considered Canada's current climate change policies, and discussed attempts to arrive at meaningful and effective strategies. 30 refs

    In light of the new recommendations of the ICRP in Report 60 on dose quantities and dose limits, this working group was set up to examine the implications for external dosimetry in Canada. The operational quantities proposed by the ICRU are discussed in detail with regard to their applicability in Canada. The current occupational dosimetry services available in Canada are described as well as the several performance intercomparisons that have been carried out within the country as well as internationally. Recommendations are given with respect to standards for dosimetry, including accuracy and precision. More practical advice is given on the choice of dosimeter to use for external dosimetry, frequency of monitoring, and who should be monitored. Specific advice is given on the monitoring of pregnant workers and problem of non-uniform irradiation. Accident and emergency dosimetry are dealt with briefly. Suggestions are given regarding record keeping both for employers and for the national dose registry. 48 refs., 6 tabs., 1 fig

    Canada, like many countries, is in the midst of primary health care reform. A key priority is to improve access to primary health care, especially in remote communities and areas with physician shortages. As a result, there is an increased emphasis on the integration of primary health care nurse practitioners. As of March 2006, legislation exists in all provinces and two territories in Canada that allows nurse practitioners (NPs) to implement their expanded nursing role. In this paper, we will briefly review the historical development of the NP role in Canada and situate it in the international context; describe the NP role, supply of NPs in the country, and the settings in which they work; propose an NP practice model framework; summarize facilitators and barriers to NP role implementation in primary health care delivery; and outline strategies to address the barriers.

  19. Restructuring of Canada's nuclear utilities: recent developments

    International Nuclear Information System (INIS)

    Business decisions relating to the electric power sector are a provincial responsibility in Canada. The federal government looks to the three nuclear utilities to manage their nuclear assets and maintain them in a way that maximizes their reliability, efficiency and overall performance. A significant development in Canada's nuclear sector in the past year was the Ontario Hydro Nuclear Asset Optimization Plan. Structural change in the North American electricity market is a major impetus for decisions regarding nuclear assets by Canada's electric power utilities. The Ontario government is now taking steps to introduce competition in the Ontario Electricity market. The province of New Brunswick, which has one reactor at Point Lepreau which supplies one-third of the province's electricity, is also taking measures to introduce competition in its electricity market.

  20. The Hybridisation of Higher Education in Canada

    Directory of Open Access Journals (Sweden)

    Douglas Shale

    2002-01-01

    Full Text Available Canada's postsecondary institutions are becoming increasingly involved with technology enhanced learning, generally under the rubric of distance education. Growth and activity in distance education stems from rapid developments in communication and information technologies such as videoconferencing and the Internet. This case study focuses on the use of new technologies, primarily within the context of higher education institutions operating in Canada's English speaking provinces. Capitalising on the interactive capabilities of "new" learning technologies, some distance education providers are starting to behave more like conventional educational institutions in terms of forming study groups and student cohorts. Conversely, new telecommunications technologies are having a reverse impact on traditional classroom settings, and as a result conventional universities are beginning to establish administrative structures reflective of those used by distance education providers. When viewed in tandem, these trends reflect growing convergence between conventional and distance learning modes, leading to the hybridisation of higher education in Canada.

  1. Action plan for electric mobility in Canada

    International Nuclear Information System (INIS)

    Electric mobility is an important emerging industry in Canada, where there is significant expertise in electric and hybrid vehicles, batteries, hybrid technologies, grid-connected technologies and fuel cell vehicles. This paper presented a case for the formation of Electric Mobility Canada, a proposed network of private companies and public sector agencies that aims to stimulate industry and provide support to government agencies involved with meeting Canada's obligations under the Kyoto Protocol, as well as in new industry sectors. The environmental, health, economic and industrial benefits of electric mobility were outlined. Current programs for electric mobility were reviewed, and details of financial incentives and initiatives were presented. An overview of electric mobility programs in the United States and Europe was provided. Research and development needs were evaluated. The former Electric Vehicle Association of Canada was discussed. An organizational structure for the proposed network was presented, along with a mission statement and outline of future goals. Recommendations for the future of the network included identifying short and long-term market opportunities for electric mobility technologies for all surface transport modes in Canada; determining research and development needs and appropriate funding and investment opportunities; determining other actions necessary to allow the electric mobility industry to play a growing role in meeting Canada's transport needs; and raising public awareness of the importance of electric mobility trends. It was concluded that the federal government should be approached for start-up funds for the network, which will be followed by further investment from provincial and business interests once the network is in place and functioning. 84 refs

Yet in drawing comparisons across Canadianprovinces, cohabitation is far more prevalent in the province of Quebec thanelsewhere. With this in mind, the purpose of the current paper is three fold. First,we set out to briefly situate the recent growth in the number of common-lawunions in Canada and Quebec into a broader historical and international context.Secondly, we review available information from the 2001 Census and the 1998General Social Survey on some of the key socioeconomic and demographiccharacteristics of persons who cohabit relative to those that marry. Thirdly, weconsider how these changes are important to public policy, and of direct interest to legislators andthe Canadian legal system. Major differences are documentedin comparing Quebec with elsewhere in Canada in terms of the education, laborforce participation, median income, income poverty and homeownership. Thedifferences documented between persons who marry relative to cohabiters arefound to be much less in Quebec than elsewhere, in a context wherebycohabitation has become far more widespread, an observation with directimplications for public policy.FrenchLa cohabitation est devenue tant prévalente au Canada qu’elle représenteactuellement le mode d’entrée dans la vie conjugale le plus répandu.

  4. The nuclear ingredient in Canada's industrialization

    International Nuclear Information System (INIS)

    The energy scene in Canada has been confused by a changing industrial and economic pattern, a proliferation of energy options, a conflict of energy priorities, and possibly a media and anti-nuclear inspired perception that electricity is expensive and not a good substitute for oil. In spite of an economic down-turn, in 1982-83 five new CANDU reactors with a combined capacity of 3000 MW were completed in Canada. Opportunities exist for increased use of electricity both in households and in industry. The benefits of nuclear power have extended beyond a reliable and economic energy supply to research advances, job creation, and the overall industrial development of the country

    1991-11-01

    Ninety-four Canadian-born psychiatric patients who committed suicide were compared with 23 foreign-born patients committing suicide in Canada. East Europeans were over-represented, and significant differences were found in the age distribution, stress, level of education, social isolation, and methods of suicide. Most foreign-born patients had come to Canada for family or economic reasons but were unemployed, with poor social integration. Employment, housing, education, social integration and a support network seem to be important in preventing these deaths. Cultural evaluation of the patient and early intervention is recommended.

    Full Text Available This mixed methods study examines whether the rural/urban distribution of credit union/caisse populaire branches differs significantly from the general urban/rural demographic pattern in Canada. It also explores whether their distribution is different from that of banks, looking at the cases of Québec and Atlantic Canada. The study finds a rural tilt among financial cooperatives in Canada, and seven key informants present their views on the results. Their responses are categorized in two main themes: why financial cooperatives are overrepresented in rural and small town areas, and why they are under-represented in urban ones. A discussion follows, and directions for further study are provided. / Cette étude utilisant des méthodes combinées examine si la distribution des succursales de coopératives d’épargne et de crédit / caisses populaires en milieu rural et urbain diffère de façon importante de la tendance démographique générale des milieux urbains et ruraux au Canada. Elle aborde aussi la question de savoir si leur distribution est différente de celle des banques en observant le cas du Québec et du Canada atlantique. L’étude révèle une tendance rurale chez les coopératives financières du Canada, et sept répondants clés donnent leur opinion sur les résultats. Les réponses des intervenants sont divisées en deux thèmes principaux : pourquoi les coopératives sont surreprésentées dans les milieux ruraux et les petites villes et pourquoi elles sont sous-représentées dans les milieux urbains. Un débat s’ensuit, et des lignes directrices sont fournies aux fins d’une étude plus approfondie.

    Full Text Available Maxime Gougis, Dongling Ma, Mohamed Mohamedi INRS-Énergie, Matériaux et Télécommunications, Varennes, Québec, Canada Abstract: In this work, we report for the first time the use of tungsten oxide (WOx as catalyst support for Au toward the direct electrooxidation of glucose. The nanostructured WOx/Au electrodes were synthesized by means of laser-ablation technique. Both micro-Raman spectroscopy and transmission electron microscopy showed that the produced WOx thin film is amorphous and made of ultrafine particles of subnanometer size. X-ray diffraction and X-ray photoelectron spectroscopy revealed that only metallic Au was present at the surface of the WOx/Au composite, suggesting that the WOx support did not alter the electronic structure of Au. The direct electrocatalytic oxidation of glucose in neutral medium such as phosphate buffered saline (pH 7.2 solution has been investigated with cyclic voltammetry, chronoamperometry, and square-wave voltammetry. Sensitivity as high as 65.7 µA cm-2 mM-1 up to 10 mM of glucose and a low detection limit of 10 µM were obtained with square-wave voltammetry. This interesting analytical performance makes the laser-fabricated WOx/Au electrode potentially promising for implantable glucose fuel cells and biomedical analysis as the evaluation of glucose concentration in biological fluids. Finally, owing to its unique capabilities proven in this work, it is anticipated that the laser-ablation technique will develop as a fabrication tool for chip miniature-sized sensors in the near future.

    Heptamethinecyanine J-aggregates display sharp, intense fluorescence emission making them attractive candidates for developing a variety of chem-bio-sensing applications. They have been immobilized on planar thiol-covered Au surfaces and thiol-capped Au nanoparticles by weak molecular interactions. In this work the self-assembly of novel thiolated cyanine (CNN) on Au(111) and citrate-capped AuNPs from solutions containing monomers and J-aggregates has been studied by using STM, XPS, PM-IRRAS, electrochemical techniques and Raman spectroscopy. Data show that CNN species adsorb on the Au surfaces by forming thiolate-Au bonds. We found that the J-aggregates are preferentially adsorbed on the Au(111) surface directly from the solution while adsorbed CNN monomers cannot organize into aggregates on the substrate surface. These results indicate that the CNN-Au interaction is not able to disorganize the large J-aggregates stabilized by π-π stacking to optimize the S-Au binding site but it is strong enough to hinder the π-π stacking when CNNs are chemisorbed as monomers. The optical properties of the J-aggregates remain active after adsorption. The possibility of covalently bonding CNN J-aggregates to Au planar surfaces and Au nanoparticles controlling the J-aggregate/Au distance opens a new path regarding their improved stability and the wide range of biological applications of both CNN and AuNP biocompatible systems.Heptamethinecyanine J-aggregates display sharp, intense fluorescence emission making them attractive candidates for developing a variety of chem-bio-sensing applications.

    2016-08-01

    The synthesis of Au@AgAu yolk-shell cuboctahedra nanoparticles formed by galvanic replacement in a seed-mediated method is described. Initially, single-crystal Au seeds are used for the formation of Au@Ag core-shell nanocubes, which serve as the template material for the deposition of an external Au layer. The well-controlled synthesis yields the formation of cuboctahedra nanoparticles with smooth inner and outer Au/Ag surfaces. The deposition/oxidation process is described to understand the formation of cuboctahedra and octahedra nanoparticles. The Au core maintains the initial morphology of the seed and remains static at the center of the yolk-shell because of residual Ag. Structural analysis of the shell indicates intrinsic stacking faults (SFs) near the surface. Energy dispersive X-ray spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS) compositional analysis show an Au-Ag nonordered alloy forming the shell. The three-dimensional structure of the nanoparticles presented open facets on the [111] as observed by electron tomography SIRT reconstruction over a stack of high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) images. The geometrical model was validated by analyzing the direction of streaks in coherent nanobeam diffraction (NBD). The catalytic activity was evaluated using a model reaction based on the reduction of 4-nitrophenol (4-NTP) by NaBH4 in the presence of Au@AgAu yolk-shell nanoparticles. PMID:27385583

  2. Canada and global warming: Meeting the challenge

    International Nuclear Information System (INIS)

    Canada accounts for ca 2% of total world emissions of greenhouse gases. Carbon dioxide emissions are by far the largest greenhouse gas source in Canada, primarily from energy consumption. On a per capita basis, Canada ranks second among industrialized countries in terms of energy related carbon dioxide emissions. Canada's northern geography and climate, its export-oriented economy with energy-intensive resource industries, and its relatively small population dispersed over a wide land mass contribute to this high per-capita value. The effects of global warming induced by greenhouse gases are outlined, including a reduction in water supplies, droughts affecting agriculture and forestry, and large-scale thawing of permafrost. A national strategy to respond to global warming has been developed which includes limiting and reducing greenhouse gas emissions, preparing for potential climatic changes, and improving scientific understanding and predictive capabilities with respect to climate change. Details of this strategy are outlined, including provincial and territorial strategies in partnership with the national strategy. 11 figs., 2 tabs

    International Nuclear Information System (INIS)

    This report describes the major effects of climatic change being experienced in different parts of Canada, and emphasizes those that they are likely to become so severe that they may disrupt social, ecological and economic systems. The report notes that the driving force behind these impacts is change in temperature, precipitation, and in extreme weather events. The report strongly suggests that greenhouse gas emissions, particularly carbon dioxide, methane and nitrous oxide will likely continue to increase due to human activities such as burning of fossil fuels for heating, cooling and transportation. Loss of tropical forests is also listed as a cause for increased greenhouse gases. In order to reduce greenhouse gas emissions into the atmosphere, Canada must use energy much more efficiently, use more alternative renewable energy source and substitute natural gas for coal and oil whenever possible. It was emphasized that the ratification of the Kyoto Protocol would slow down the rate of increase of the world's greenhouse gas emissions, which in turn affect atmospheric concentrations. The author states that Canada's ratification of the Kyoto Protocol is key to global success, particularly since some countries have backed away from it and some are wavering. The report outlined the following major impacts of climate change in various parts of Canada: sea ice, permafrost, forest fires, transportation, toxic contaminants, storminess, precipitation, water supply, water quality, fisheries, hydropower, agriculture and human adaptation. refs., tabs

  10. Recent developments in Canada's climate change program

    International Nuclear Information System (INIS)

    This paper surveys Canada's official response to the responsibilities it took on with the Kyoto Protocol. In order to meet Kyoto targets for the timeframe 2008-2012, greenhouse gas emissions need to be reduced by 33 percent below what they currently are. Two billion Canadian dollars have been allocated to this effort. The government of Canada's official stance is that carbon dioxide levels have been rising more rapidly than at any other time in the last half million years. Canada's main efforts in the mining and minerals sector have been to find a replacement for sulphur hexafluoride, reduce emissions of perfluorocarbons, and demonstrate the use of hydrogen as a fuel for underground mining vehicles. According to the author, the most important contribution has been the use of supplementary cementing material such as fly ash, ash, and ground blast furnace slag. These materials have partially replaced cement in concrete. Canada expects to reduce carbon dioxide emissions this way by about 1.5 million tonnes per year. EcoSmart, a non-profit organization, is the main vehicle for this effort. 8 refs., 7 figs

  20. TransCanada PipeLines Limited 1998 annual report : TransCanada energy solutions

    International Nuclear Information System (INIS)

    Financial information from TransCanada PipeLines Limited and a review of the company's 1998 operations was made available for the benefit of shareholders. TransCanada's pipeline system transports natural gas and crude oil from Western Canada Sedimentary Basin to North America's major energy markets. Net earnings from continuing operations for 1998, before unusual charges, were $575 million ($ 355 million after unusual charges) compared to $522 million for 1997. Solid performances from the energy transmission and international business, when compared to 1997, were more than offset by a decreased contribution from energy processing. TransCanada recorded integration costs of $166 million, after tax, related to the merger with NOVA in 1998, which was the major operational accomplishment during the year, creating a seamless economic energy delivery, processing and marketing system from the wellhead to the market. tabs., figs

  1. Synthesis of ultrathin face-centered-cubic Au@Pt and Au@Pd core-shell nanoplates from hexagonal-close-packed Au square sheets

    2015-03-17

    The synthesis of ultrathin face-centered-cubic (fcc) Au@Pt rhombic nanoplates is reported through the epitaxial growth of Pt on hexagonal-close-packed (hcp) Au square sheets (AuSSs). The Pt-layer growth results in a hcp-to-fcc phase transformation of the AuSSs under ambient conditions. Interestingly, the obtained fcc Au@Pt rhombic nanoplates demonstrate a unique (101)f orientation with the same atomic arrangement extending from the Au core to the Pt shell. Importantly, this method can be extended to the epitaxial growth of Pd on hcp AuSSs, resulting in the unprecedented formation of fcc Au@Pd rhombic nanoplates with (101)f orientation. Additionally, a small amount of fcc (100)f-oriented Au@Pt and Au@Pd square nanoplates are obtained with the Au@Pt and Au@Pd rhombic nanoplates, respectively. We believe that these findings will shed new light on the synthesis of novel noble bimetallic nanostructures. Phase change: Ultrathin Au@Pt and Au@Pd core-shell nanoplates were prepared from Au square sheets. A phase transformation from hexagonal close-packed (hcp) to face-centered cubic (fcc) is observed upon coating the hcp Au square sheets with Pt or Pd under ambient conditions. The prepared fcc Au@Pt and Au@Pd rhombic nanoplates demonstrate unique (101)f orientation (picture shows a typical fcc Au@Pt rhombic nanoplate). © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

  8. Introducing small modular reactors into Canada

    International Nuclear Information System (INIS)

    In recent years there has been a growing interest in smaller, simpler reactors for generating electricity and process heat. This is evidenced in the growing body of literature and the increasingly frequent meetings and conferences on the subject. The interest in Small Modular Reactors (SMRs) is driven to a large extent by the desire to reduce capital costs, to reduce greenhouse gas emissions, to replace retiring fossil plants that do not meet today's environmental standards, and to provide power in locations away from large electrical grids. These drivers are as important in Canada as they are in the U.S., where the design and licensing of SMRs is being most vigorously pursued. They have led to a growing interest in Canada as a potentially significant market for SMRs, particularly in the Western Provinces of Alberta and Saskatchewan and in the remote First Nations communities of Northern Canada. There is a growing body of literature addressing the regulation and licensing of Small Modular Reactors in the U.S. Issues being identified in there can generally be categorized as licensing framework issues, licensing application issues, and design and manufacturing issues. Many of these issues are embedded in the US regulatory framework and can only be resolved through changes in the regulations. For the most part these issues are equally applicable in Canada and will need to be addressed in introducing SMRs here. A significant difference, however, is that these issues can be addressed within the Canadian regulatory framework without requiring changes in the regulations. The CNSC has taken a very proactive stance regarding the licensing of small reactors in Canada. They have published two new Regulatory Documents stipulating the requirements for licensing small reactors. A key feature is that they allow the application of a 'graded approach' in which the stringency of the design measures and analyses applied are commensurate with the level of risk posed by

    Full Text Available Can consumers contribute to a more sustainable world? In this article we describe alternative consumption in Norway, exemplified by organic food, and discuss the role of consumers in promoting change. The paper is based on studies undertaken at the Norwegian National Institute for Consumer Research (SIFO during the last 15 years. The analysis starts by considering the origin of the organic movement in Norway and follows its development, showing that over the years consumption of organic products has reached a noteworthy position in the conventional market. While organic products seem to face conventionalisation, other alternative initiatives are emerging, such as fair trade, farmers’ market, farm food outlets, box schemes and community supported agriculture (CSA. Agreeing with the critique of a ‘generic active consumer model’, the article makes the case that the consumer’s role must be understood contextually and within its limitations. At the same time, the data presented in this article show that within shifting contextual frameworks, consumers utilise consumption with the goal of producing change. The paper suggests that forms of consumption defined as alternative are socially contested and the products that consumers identify as alternative are those that, in a given time and space, best reflect alternative values.Les consommateurs peuvent-ils contribuer à un monde plus durable? Dans cet article nous décrivons la consommation alternative en Norvège à travers l’exemple des aliments bio, et nous discutons le rôle des consommateurs dans la promotion du changement. Cet article se fonde sur des recherches entreprises par l’Institut national de la recherche sur les consommateurs (SIFO en Norvège, au cours des 15 dernières années.

  10. Greenhouse gas reduction and Canada's nuclear industry

    International Nuclear Information System (INIS)

    The Kyoto Protocol of the United Nations Framework Convention on Climate change, dated December 10, 1997 committed Canada to reduce greenhouse gases to 6% below 1990 levels by 2008-2012. Subsequently the federal government initiated a broad review of the implications of such a reduction across all sectors of the Canadian economy to identify options for eventual implementation. The Canadian nuclear industry participated in this review. This paper examines the status of this review to date and identifies options, which may significantly influence the use of nuclear energy domestically and internationally. This paper provides a review of options established by the three key Issue Tables in the context of implications to the nuclear industry. Several of the other Issue Tables have also identified options, which have major future implications for the use of nuclear energy. For example the Transportation Table has addressed the possible production and use of hydrogen fuel as an energy carrier. Biological and geological sinks are emerging technologies which will likely lead to increased energy demand. Development of the necessary infrastructure to support these new technologies could lead to a substantial need for increased production of electricity from greenhouse gas free sources in Canada in coming decades. In conclusion, international concern with climate changes re-focuses attention to human application of nature's energy sources. The studies implemented by the climate change secretariat have resulted in a comprehensive evaluation of opportunities for Canada to contribute to reduction of greenhouse gas emissions in Canada and abroad. The ability of Canada's nuclear industry to provide greenhouse gas free energy in the large quantities needed by modern society is recognized. (author)

    The photoluminescence characteristics of Au(0)@Au(I)-thiolate Core–shell nanoclusters (Au-NCs), whose size is <2 nm, are investigated. We use the time-resolved single-photon counting technique and the transient absorption technique to distinguish the mechanism of the photoluminescence of Au-NCs. The dynamic spectral data show that the photoluminescence mechanism should be composed of the fluorescence and the phosphorescence. Meanwhile, Au-NCs have the aggregation induced photoluminescence enhancement property, which is attributed to the suppression of conversion from the singlet state to triplet state when they aggregated together. In addition, the photoluminescence characteristics of aggregated Au-NCs should be further improved through infiltrating them into photonic crystals.

  14. A comparative study of Ge/Au/Ni/Au-based ohmic contact on graphene

    International Nuclear Information System (INIS)

    Superior graphene—metal contacts can improve the performance of graphene devices. We report on an experimental demonstration of Ge/Au/Ni/Au-based ohmic contact on graphene. The transfer length method (TLM) is adopted to measure the resistivity of graphene-metal contacts. We designed a process flow, which can avoid residual photoresist at the interface of metal and graphene. Additionally, rapid thermal annealing (RTA) at different temperatures as a post-processing method is studied to improve graphene—metal contact. The results reveal that the contact resistivity of graphene and Ge/Au/Ni/Au can reach 10−5 Ω·cm2 after RTA, and that 350 °C is optimum annealing temperature for the contact of graphene—Ge/Au/Ni/Au. This paper provides guidance for fabrication and applications of graphene devices. (semiconductor technology)

    We present transverse momentum distributions of charged hadrons produced in Au+Au collisions at sqrt(s_NN) = 200 GeV. The evolution of the spectra for transverse momenta p_T from 0.25 to 5GeV/c is studied as a function of collision centrality over a range from 65 to 344 participating nucleons. We find a significant change of the spectral shape between proton-antiproton and peripheral Au+Au collisions. Comparing peripheral to central Au+Au collisions, we find that the yields at the highest p_T exhibit approximate scaling with the number of participating nucleons, rather than scaling with the number of binary collisions.

    Three Au-based nanomaterials (silica@Au nanoshells, hollow Au/Ag nanospheres and Au nanorods) were evaluated for their comparative photothermal efficiencies at killing three types of malignant cells (A549 lung cancer cells, HeLa cervix cancer cells and TCC bladder cancer cells) using a CW NIR laser. Photodestructive efficiency was evaluated as a function of the number of nanoparticles required to destroy the cancer cells under 808 nm laser wavelength at fixed laser power. Of the three nanomaterials, silica@Au nanoshells needed the minimum number of particles to produce effective photodestruction, whereas Au nanorods needed the largest number of particles. Together with the calculated photothermal conversion efficiency, the photothermal efficiency rankings are silica@Au nanoshells > hollow Au/Ag nanospheres > Au nanorods. Additionally, we found that HeLa cells seem to present better heat tolerance than the other two cancer cell lines.

  18. Electrical conduction through self-assembled monolayers in molecular junctions: Au/molecules/Au versus Au/molecule/PEDOT:PSS/Au

    International Nuclear Information System (INIS)

    We fabricated and characterized a large number of octanedithiol (denoted as DC8) molecular devices as vertical metal-molecule-metal structure with or without using an intermediate conducting polymer layer of poly (3,4-ethylenedioxythiophene) stabilized with poly(4-styenesulfonic acid) (called as PEDOT:PSS). The electronic transport properties of DC8 molecular devices with and without PEDOT:PSS layer were statistically compared in terms of current density and device yield. The yields of the working molecular devices were found to be ∼ 1.75% (84 out of 4800 devices) for Au/DC8/Au junctions and ∼ 58% (74 out of 128 devices) for Au-DC8/PEDOT:PSS/Au junctions. The tunneling decay constants were obtained with the Simmons tunneling model and a multibarrier tunneling model for two kinds of molecular devices with and without PEDOT:PSS layer.

  19. Proton channeling in Au at low energies

    International Nuclear Information System (INIS)

    The electronic energy loss for low velocity protons channeled in the direction single crystal Au is calculated. The spatial distribution of valence electronic density in Au is calculated using Tight Binding Linear Muffin Tin Method. The proton trajectories are determined by numerical integration of the classical motion equation, and the energy loss is evaluated using the calculated valence electronic density in the friction term. The results allow to describe qualitatively the non linear behavior of energy loss with ion velocity observed experimentally. (author)

The lack of suppression in d + Au collisions suggests that it is unlikely that initial state effects can explain the suppression in the central Au + Au collisions. PACS: 25.75.-q

    Identified charged-particle spectra of π±, K±, p, and pmacr at midrapidity (|y|<0.1) measured by the dE/dx method in the STAR (solenoidal tracker at the BNL Relativistic Heavy Ion Collider) time projection chamber are reported for pp and d+Au collisions at sNN=200 GeV and for Au+Au collisions at 62.4, 130, and 200 GeV. Average transverse momenta, total particle production, particle yield ratios, strangeness, and baryon production rates are investigated as a function of the collision system and centrality. The transverse momentum spectra are found to be flatter for heavy particles than for light particles in all collision systems; the effect is more prominent for more central collisions. The extracted average transverse momentum of each particle species follows a trend determined by the total charged-particle multiplicity density. The Bjorken energy density estimate is at least several GeV/fm3 for a formation time less than 1 fm/c. A significantly larger net-baryon density and a stronger increase of the net-baryon density with centrality are found in Au+Au collisions at 62.4 GeV than at the two higher energies. Antibaryon production relative to total particle multiplicity is found to be constant over centrality, but increases with the collision energy. Strangeness production relative to total particle multiplicity is similar at the three measured RHIC energies. Relative strangeness production increases quickly with centrality in peripheral Au+Au collisions, to a value about 50% above the pp value, and remains rather constant in more central collisions. Bulk freeze-out properties are extracted from thermal equilibrium model and hydrodynamics-motivated blast-wave model fits to the data. Resonance decays are found to have little effect on the extracted kinetic freeze-out parameters because of the transverse momentum range of our measurements. The extracted chemical freeze-out temperature is constant, independent of collision system or centrality; its value is close

  4. Au-Pt alloy nanocrystals incorporated in silica films

    2005-01-01

    Au, Pt and Au-Pt alloy nanocrystals have been prepared in thin SiO2 film matrices by sol-gel spin-coating, followed by heating at 450 uC in 10% $H_{2}$-90% Ar. X-Ray diffraction patterns reveal that the Au and Au-Pt nanocrystals have a preferential (111) orientation. Upon increasing the Pt concentration, part of the Pt does not alloy with Au, but instead forms a shell around the Au-Pt alloy core. The alloy composition itself goes up to Au(50) : Pt(50), and the Pt shells are formed around the ...

  5. XAFS studies of Au nanocrystals passivated by different surfactants

    International Nuclear Information System (INIS)

    The electronic and atomic structures of Au nanocrystals affected by different surfactants (PPh3, PVP, and dodecanethiol) capping were studied by X-ray absorption fine structure (XAFS) at Au L3-edge. For PPh3, PVP, and dodecanethiol-capped Au nanocrystals, the surface Au atoms interact with P, O, and S atoms respectively; however, only for dodecanethiol-capped Au nanocrystals, a significant electron transfer between Au and S atoms is observed. The extend-XAFS results reveal that the atomic structure disorder of Au-Au shell gradually increases from 0.0095 to 0.0152 Å2 when the surfactants goes from PPh3 to dodecanethiol. These results suggest that the surfactants would change the electronic and atomic structures of Au nanocrystals rather than merely passivates on the surface of Au nanocrystals.

    Full Text Available EnglishThe individual decision to immigrate is made in the context of larger socialstructures that influence the composition of the economic immigrant populationover time. Over the last 20 years, economic immigrants to Canada have facedchanging selection policies, cycles of economic recession and growth, increaseddemand for information technology skills, women's increased labour forceparticipation and an aging labour force. Using data from Statistics Canada'sLongitudinal Immigration Database (IMDB, this paper examines the flow ofeconomic immigrants to Canada by their occupational composition from 1980 to2000. Relative to Canadians, when all immigrants from this period are groupedtogether, their economic integration is slow and does not reach parity withCanadians before 16 years. Among skilled worker immigrants, whereas theearlier cohorts did well but did not improve much over time, later cohorts startedoff in a relatively worse position, but early indications show a fairly steep slopeto better relative average earnings. These differences support the need toexamine immigrant integration by both the class of immigrant and the context atthe time of immigration.FrenchLa décision d’immigrer est une décision personnelle prise dans le plus largecontexte des structures sociales qui, à leur tour, exercent une influence sur lacomposition de la population immigrante selon les époques.

  7. Suppression of ϒ production in d+Au and Au+Au collisions at √(sNN)=200 GeV

    International Nuclear Information System (INIS)

    We report measurements of ϒ meson production in p+p, d+Au, and Au+Au collisions using the STAR detector at RHIC. We compare the ϒ yield to the measured cross section in p+p collisions in order to quantify any modifications of the yield in cold nuclear matter using d+Au data and in hot nuclear matter using Au+Au data separated into three centrality classes. Our p+p measurement is based on three times the statistics of our previous result. We obtain a nuclear modification factor for ϒ(1S+2S+3S) in the rapidity range |y|<1 in d+Au collisions of RdAu=0.79±0.24(stat.)±0.03(syst.)±0.10(p+p syst.). A comparison with models including shadowing and initial state parton energy loss indicates the presence of additional cold-nuclear matter suppression. Similarly, in the top 10% most-central Au+Au collisions, we measure a nuclear modification factor of RAA=0.49±0.1(stat.)±0.02(syst.)±0.06(p+psyst.), which is a larger suppression factor than that seen in cold nuclear matter. Our results are consistent with complete suppression of excited-state ϒ mesons in Au+Au collisions. The additional suppression in Au+Au is consistent with the level expected in model calculations that include the presence of a hot, deconfined Quark–Gluon Plasma. However, understanding the suppression seen in d+Au is still needed before any definitive statements about the nature of the suppression in Au+Au can be made

The objective of the analysis is to better understand how individuals make decisions to volunteer time toward CED initiatives and to determine whether the determinants of participation in CED are unique when compared to those of participation in volunteer activities in general. The dataset employed is Statistics Canada's 2004 Canada Survey of Giving, Volunteering and Participating (CSGVP. To date, there has been no prior econometric analysis of the decision to participate in community economic development initiatives in Canada. Results suggest a role for both public policymakers and practitioners in influencing participation in CED. / Cet article constitue une analyse empirique du processus de prise de décision chez les individus en ce qui a trait à la participation aux initiatives canadiennes de développement économique communautaire (DÉC.

Elle sert aussi à trancher la question de savoir si les facteurs de participation aux initiatives de développement économique communautaire sont uniques ou communs à la participation à des activités bénévoles en général. Les données employées dans le cadre de cette analyse sont puisées de l'Enquête canadienne sur le don, le bénévolat et la participation effectuée par Statistique Canada en 2004. À ce jour, aucune analyse économétrique n'a été menée sur la décision de participer aux initiatives canadiennes de DÉC.

    This article provides information on Alzheimer's disease and other dementias, using the 2010/2011 Canadian Community Health Survey, the 2011/2012 Survey of Neurological Conditions in Institutions in Canada, and the 2011 Survey on Living with Neurological Conditions in Canada. Among Canadians aged 45 or older, an estimated 0.8% in private households and 45% in long-term residential care facilities had a diagnosis of dementia. Prevalence rose with age. The vast majority of people with dementia in private households received assistance with medical care (81%), housework and home maintenance (83%), meal preparation (88%), emotional support (90%), transportation (92%), and managing care (92%). Among those receiving assistance, 85% relied, at least in part, on family, friends or neighbours. The primary caregiver tended to be a spouse (46%) or an adult child (44%), most of whom were daughters (71%). The majority of primary caregivers lived in the same household (83%) and provided daily care (86%). PMID:27192206

  11. Canada's climate change policy in context

    International Nuclear Information System (INIS)

    Climate change has a wide range of implications for the health, well-being, and economic prospects for Canadians, and for the ecological systems that sustain life on this planet. The overwhelming scientific opinion, world leaders and even a growing number of corporate leaders now agree that the Earth is undergoing a significant and unusual warming period as a result of the build-up of greenhouse gases in the atmosphere. There is also wide agreement that much of this build-up is anthropogenic, and that a global effort is required to slow this trend. Because climate change is a global problem, it requires global solutions by way of reduction in global greenhouse gas emissions. In this context, the Kyoto Agreement of 1997 constitutes a major breakthrough, even though it takes only a small step towards towards altering the human impact on global climate. Although some 80 states, plus the European Union signed the Kyoto Protocol, it remains unclear when it will come into force because the majority of states have failed to ratify it, pending the resolution of a variety of technical and operational details. Canada is the second highest emitter of greenhouse gases (16 tonnes per capita, compared to world average of 3.6 tonnes per capita). This, combined with Canada's foreign policy goals of playing a leading role in taking action and preserving its reputation as an honest broker, makes the challenge of meeting Canada's Kyoto commitments especially pressing. The purpose of this paper is to explain Canada's climate change policy in the context of these international and domestic pressures. The paper identifies the main climate change-related policy challenges, international responses to date and the constraints and opportunities open to Canada in the light of its economy, its federalist political structure, and place in the world as a middle power, as well as its geographic situation, natural resources and environmental endowment. There is a detailed discussion of the Kyoto

    International Nuclear Information System (INIS)

    The history of providing public information on nuclear energy in Canada for more than 40 years is described. Information centers are part of all nuclear power plants and they receive many thousands of visitors each year. Until the 1970s public information programs were relatively easy. There was a lot of interest in nuclear energy, and there was little debate about it or opposition to it. But times have changed, and Canadian public information strategies and tactics have evolved to meet challenge of answering increasing public concerns. In the past 20 years Canada has gone through three phases in relationship with the public: information, communication, participation. Activities on implementation of these phases are outlined

    2009-01-01

    We performed a qualitative study of the practice of informed consent for videoconsultation in Canada. Fourteen cases were examined: the 13 provinces and territories, and the Federal jurisdiction representing aboriginal groups. Twenty-seven interviews were conducted with key informants (14 telehealth experts, 13 legal experts). The telehealth experts were people with direct experience of telehealth practice. The majority of the telehealth experts agreed that videoconsultations had not been integrated into the health-care system. An interesting finding of the study was that the integration status of videoconsultations was not indicative of informed consent practices. Telehealth providers favoured express written consent, or risk management practices, although there was a desire to move towards implied consent models for videoconsultations. The study also showed that the legal ramifications of the electronic transmission of non-recorded, real-time, personal health information had not been explored. This represents an important factor in guiding future consent for videoconsultations in Canada. PMID:19471027

    The carbon disclosure project conducts an annual survey to determine the strategies and actions of major cap companies in relation to climate change. This report discussed initiatives implemented by Canada's largest companies to prepare for a carbon-constrained future. The report documented results from 97 companies. The aim of the report was to help companies make use of the disclosures as reference points for future carbon markets and regulations relating to reporting requirements. Results of the survey demonstrated that Canada's low-carbon and high-carbon impact sectors have implemented several significant initiatives and best practices for operations. However, widespread engagement in a comprehensive manner has yet to be achieved. Many respondents were in the process of developing a more balanced risk-opportunity agenda in relation to climate change, and nearly half of all respondents have implemented governance arrangements or personal incentives in both both the high-carbon and low-carbon impact sectors. 5 tabs., 26 figs.

  19. Nuclear fuel waste policy in Canada

    International Nuclear Information System (INIS)

    The 1996 Policy Framework for Radioactive Waste established the approach in Canada for dealing with all radioactive waste, and defined the respective roles of Government and waste producers and owners. The Policy Framework sets the stage for the development of institutional and financial arrangements to implement long-term waste management solutions in a safe, environmentally sound, comprehensive, cost-effective and integrated manner. For nuclear fuel waste, a 10-year environmental review of the concept to bury nuclear fuel waste bundles at a depth of 500 m to 1000 m in stable rock of the Canadian Shield was completed in March 1998. The Review Panel found that while the concept was technically safe, it did not have the required level of public acceptability to be adopted at this time as Canada's approach for managing its nuclear fuel waste. The Panel recommended that a Waste Management Organization be established at arm's length from the nuclear industry, entirely funded by the waste producers and owners, and that it be subject to oversight by the Government. In its December 1998 Response to the Review Panel, the Government of Canada provided policy direction for the next steps towards developing Canada's approach for the long-term management of nuclear fuel waste. The Government chose to maintain the responsibility for long-term management of nuclear fuel waste close with the producers and owners of the waste. This is consistent with its 1996 Policy Framework for Radioactive Waste. This approach is also consistent with experience in many countries. In addition, the federal government identified the need for credible federal oversight. Cabinet directed the Minister of NRCan to consult with stakeholders, including the public, and return to ministers within 12 months with recommendations on means to implement federal oversight.

Given the alarming prevalence, severity and impact of household food insecurity in Canada, Dietitians of Canada calls for a pan-Canadian, government-led strategy to specifically reduce food insecurity at the household level, including policies that address the unique challenges of household food insecurity among Indigenous Peoples. Regular monitoring of the prevalence and severity of household food insecurity across all of Canada is required. Research must continue to address gaps in knowledge about household vulnerability to food insecurity and to evaluate the impact of policies developed to eliminate household food insecurity in Canada. Dietitians of Canada recommends: Development and implementation of a pan-Canadian government-led strategy that includes coordinated policies and programs, to ensure all households have consistent and sufficient income to be able to pay for basic needs, including food. Implementation of a federally-supported strategy to comprehensively address the additional and unique challenges related to household food insecurity among Indigenous Peoples, including assurance of food sovereignty, with access to lands and resources, for acquiring traditional/country foods, as well as improved access to more affordable and healthy store-bought/market foods in First Nation reserves and northern and remote communities. Commitment to mandatory, annual monitoring and reporting of the prevalence of marginal, moderate and severe household food insecurity in each province and territory across Canada, including among vulnerable populations, as well as regular evaluation of the impact of poverty reduction and protocols for

    Charged particle pseudorapidity distributions have been measured in Au + Au collisions using the BRAHMS detector at RHIC. The results are presented as a function of the collision centrality and the center of mass energy. They are compared to the predictions of different parton scattering models and the important role of hard scattering processes at RHIC energies is discussed.

    One of the best methods for producing bulk homogeneous (composition) supported bimetallic AuPd clusters involves the immobilization of a protected Au seed followed by the addition of Pd. This paper investigates the importance of this gold seed in controlling the resulting bimetallic AuPd clusters structures, sizes and catalytic activities by investigating three different gold seeds. Uniform Au-Pd alloy were obtained when a steric/electrostatic protecting group, poly(vinyl alcohol) (PVA), was used to form the gold clusters on activated carbon (AC). In contrast Au/AC precursors prepared using Au nanoparticles with only electrostatic stabilization (tetrakis(hydroxypropyl)phosphonium chloride (THPC)), or no stabilization (magnetron sputtering) produced inhomogeneous alloys and segregation of the gold and palladium. The uniform alloyed catalyst (Pd{at}Au{sub PVA}/AC) is the most active and selective catalyst, while the inhomogenous catalysts are less active and selective. Further study of the PVA protected Au clusters revealed that the amount of PVA used is also critical for the preparation of uniform alloyed catalyst, their stability, and their catalytic activity.

    Full Text Available The adsorption of the proteins CD13, mucin and bovine serum albumin on VLGXE-Au and YNGRT-Au interfaces was monitored by electrochemical impedance spectroscopy in the presence of [Fe(CN6]3−/4−. The hydrophobicity of the Au surface was tailored using specific peptides, blocking agents and diluents. The combination of blocking agents (ethanolamine or n-butylamine and diluents (hexanethiol or 2-mercaptoethanol was used to prepare various peptide-modified Au surfaces. Protein adsorption onto the peptide-Au surfaces modified with the combination of n-butylamine and hexanethiol produced a dramatic decrease in the charge transfer resistance, Rct, for all three proteins. In contrast, polar peptide-surfaces induced a minimal change in Rct for all three proteins. Furthermore, an increase in Rct was observed with CD13 (an aminopeptidase overexpressed in certain cancers in comparison to the other proteins when the VLGXE-Au surface was modified with n-butylamine as a blocking agent. The electrochemical data indicated that protein adsorption may be modulated by tailoring the peptide sequence on Au surfaces and that blocking agents and diluents play a key role in promoting or preventing protein adsorption. The peptide-Au platform may also be used for targeting cancer biomarkers with designer peptides.
