    This document presents, by region, the localization of existing radioactive wastes in France at the date of December 31, 2004. In addition to the geographic situation, this inventory is presented by site and by category of waste producer or owner. The collection of these data is based on the free declaration made by waste owners or producers. The gathered information has been reformatted and homogenized and is reported in a synthetic way in the form of tables and files. Thus, 899 sites have been indexed, among which 159 are presented in the form of a detailed file. For each region, a table details the registered sites by category of producer/owner and the location of the main ones is reported on a regional map. The registered waste producers are radionuclide users belonging to 4 specific domains: medical, research, industry and national defense. The corresponding wastes are in general modest both in quantity and activity. The sites polluted by radioactive substances are also mentioned, even if they are already decontaminated or not. (J.S.)

    2001-11-01

    Full Text Available Au cours des dernières décennies, les cultures pérennes ont connu un formidable essor dans les zones tropicales humides. Grâce à une demande toujours croissante en chocolat, café et caoutchouc naturel, les plantations de cacaoyers, de caféiers et d’hévéas se sont répandues sur plusieurs dizaines de millions d’hectares à travers tous les continents. Pour ce qui concerne les oléagineux, les cultures de cocotiers et, plus récemment, de palmiers à huile, ont connu des évolutions comparables. Les retours financiers que procurent ces cultures sont considérables et pèsent souvent de manière déterminante sur les économies des pays producteurs. Par ailleurs, ces productions agricoles alimentent aussi des filières économiques dynamiques et importantes pour les pays du Nord, telles que celles des pneumatiques, de l’agro-alimentaire ou des produits cosmétiques. Cependant, le nouveau contexte de politiques libéralisées et mondialisées, ainsi que l’émergence de questions nouvelles sur la gestion durable des territoires et des ressources naturelles, amènent à s’interroger sur la place qui sera réservée à ces productions agricoles au cours du xxie siècle.

    Full Text Available Nous étudions la sémantique des noms d’humains dans le lexique français. Dans la littérature, ces noms ont un positionnement indéterminé ou ambigu par rapport au critère concret/abstrait. Ce fait est regrettable car ce critère est considéré comme fondamental. Nous montrons leur positionnement particulier vis-à-vis de ce critère au travers de l’étude de métaphores attestées en corpus dans divers textes écrits. Nous suivons l’optique de Lakoff et Johnson en considérant que la métaphore est un révélateur des catégories de pensée. Dans cet esprit, la question est de savoir si les humains sont des entités matérielles ou non. L’étude est menée sur deux paramètres définitoires des entités matérielles : la masse et la spatialité. Nous apportons des caractérisations lexicales de ces deux propriétés. La masse est envisagée généralement, autour des noms, adjectifs et verbes relevés dans les dictionnaires. Nous proposons une synthèse des divers paramètres dénotant la spatialité dans la littérature, sous la forme de six points indépendants (forme, intérieur/extérieur, sous-parties, changement de posture, localisation, déplacement. L’étude de la spatialité est menée systématiquement dans ces directions grâce à des tests issus des caractérisations lexicales de ces aspects. Les tests font voir que, si les humains sont dotés d’une certaine dimension matérielle (qu’ils partagent ainsi avec les objets concrets, ils ont également au moins trois autres dimensions qui font qu’ils ne se réduisent pas à des objets matériels. Nous montrons ainsi que l’humain est, dans le lexique français, doté d’une multiplicité ontologique : en plus d’une dimension matérielle, il dispose d’une dimension psychologique, une dimension praxéologique et une dimension sociale. De plus, l’étude des métaphores montre que la dimension matérielle est souvent réduite voire anéantie par rapport aux

São marcos visíveis no corpo físico e cada cultura os investe de sua rubrica. Na nossa cultura, historicamente, associam-se à menopausa inúmeras afecções (físicas e psíquicas. A partir do trabalho de Robert Wilson, publicado no livro Eternamente Feminina (1966, a menopausa adquire o estatuto de doença e a sua prevenção, tratamento e cura vinculam-se à terapia de reposição hormonal (TRH. Os diferentes discursos que circulam sobre a menopausa em nossa cultura não só contribuem para que tal associação seja mantida, como partem do pressuposto que as questões relacionadas à menopausa e envelhecimentos se apresentam igualitariamente às mulheres, independentemente de sua condição física, psíquica, social, econômica e cultural. O estudo tem como objetivo abordar alguns aspectos da construção da menopausa em nossa cultura e simultaneamente mostrar o quanto este evento deve ser percebido em seu caráter particular e relativo, e não como sendo da ordem do universal ou padronizado.

    Full Text Available Jean-Pierre Berlan, en 1999, a critiqué le choix de la voie hybride chez le maïs [1]. Cependant, il ne dit pas ce qu’il aurait fallu faire comme type de variétés pour avoir le même progrès économique dans la culture du maïs. Chez cette espèce, le clonage étant exclu, si ce n’est pas la voie lignée, c’est la voie population. Nous allons donc comparer ces deux voies à la voie hybride. Pour cela, nous allons d’abord nous placer dans le cas où les effets des gènes sont tels qu’ils permettent, en théorie, d’obtenir des lignées aussi bonnes que les hybrides, c’est-à-dire qu’il n’y a pas d’avantage de l’état hétérozygote à un locus (encadré 1. Il est en effet évident que s’il y a des mécanismes génétiques qui font que l’état hétérozygote à un locus est meilleur que l’état homozygote (on dit qu’il y a superdominance, alors il faudra développer des hybrides. Nous montrerons que, même en dehors de cette situation, la voie hybride est la seule qui puisse apporter le maximum de rendement et de marge brute à l’hectare, et cela pendant un temps assez long (plus d’un siècle. Nous considérerons le cas de superdominance, ou de situations apparentées, dans une seconde étape.

    Full Text Available This essay argues that through the narrative techniques of point of view and embedding, Beauvoir carefully constructed her narrative and those of her male and female characters in Tous les hommes sont mortels , her third novel, published in 1946, in order to explain why males dominate society and to encourage women to fight against the current patriarchal social order. Many critics view Fosca as the principal character, and his 400-page embedded recapitulation of his past as the predominant text, but shifting the focus from Fosca to Régine, who constitutes the only focalizer of present events in the embedding text, clarifies many details previously judged as faults. This study advances that the awkwardness of the characters and of the linking of the narrative strands needs to be reinterpreted in relation to thematic repetitions and contradictions, the narrator's reliability, the use of time, psychoanalytic theory, the author's life at the time of writing, cultural history, and theories concerning énonciation . The interplay of these elements indicates the ways in which narrative is wielded as a weapon which ultimately promotes female independence in the struggle between the sexes.

    The first part of this thesis presents the regulatory framework and the technical context linked with the study of stabilized/solidified wastes and with the evaluation of stabilization/solidification processes. A presentation of the two type of ultimate wastes under study (a used catalyst and an activated charcoal) and an analysis of the processes is given. The second part is devoted to the experimental characterization of both types of porous wastes. The third part deals with the processing of such wastes using an hydraulic binder. The study stresses on both on the stabilization/solidification efficiency of the process and on the conditions of its implementation. The same work is made for a process that uses a bituminous binder. Some choice criteria for the selection of the better process are deduced from the examination of the overall data collected. The waste characterization methodology is applied six times: two times for the raw wastes, two times for the same wastes processed with an hydraulic binder, and two times for the same wastes processed with a bituminous binder.

    Lemarie Stéphane

    2001-05-01

    Full Text Available Les OGM actuellement sur le marché présentent des innovations sur des fonctions de protection des plantes. Selon les problèmes de protection des plantes, les gains des agriculteurs liés à l’adoption des OGM sont très variables. Cette hétérogénéité pose d’importants problèmes méthodologiques pour pouvoir estimer correctement la distribution des gains pour l’ensemble des agriculteurs. Une synthèse de plusieurs études américaines est réalisée ici et met bien en évidence la diversité des méthodes utilisées, chacune d’elles présentant ses avantages et ses limites. Globalement, si la diffusion des OGM est un fait indéniable, les études ne permettent pas de tirer des conclusions aussi nettes quant à l’impact des OGM pour tous les agriculteurs qui adoptent ces produits, et cela en particulier pour le soja. Cette absence de conclusion s’explique en grande partie par la difficulté à mesurer certains facteurs qui influencent le comportement d’adoption, comme par exemple la simplification de la conduite des cultures. En contrepartie, il faut noter que les études présentées ici ne prennent pas en compte un certain nombre d’effets indirects qui peuvent faire diminuer les gains des agriculteurs.

Les efforts déployés en réaction se sont révélés être si désordonnés qu’ils risquent de ne pas être très efficaces. Plus à l’est, les riverains du détroit de Malacca ont réussi à chasser les pirates. Cependant, ce succès souvent montré en exemple demeure relatif et en aucun cas dû aux seules patrouilles mises en place.Since last August, there were markedly more attacks registered off the Horn of Africa. The lack of coordination between the numerous initiatives is making surveillance operations inefficient. Further in the east, the littoral States along the Malacca Straits have managed to expel the pirates. Nevertheless, this success – often showed as an example – is not total. Moreover, it is not only due to the sea and air patrols.

    The project of a repository is a part of an iterative optimization process of the safety of disposal. It contains the specifications of the wastes admitted to the repository and the safety analyses of the repository containing the wastes. In a general way, the study has refined the idea of type A repositories as defined in the 1978 concept of NAGRA and has shown possibilities for realization. It could be shown that the realistic geologic conditions that have been considered will not hinder the construction of the repository. It has proved that the realization and maintenance of a reliable artificial barrier for 100 years is technically realizable. Technological alternatives are available to overcome the difficulties which will be met. The radiation protection of the working personnel will be assured through adequate conception of the installations and careful planning of the operations. The work and the equipment can be conceived without major difficulties in order that the risk incurred relative to various accidents is reduced to an acceptable level.

The only reasonable energy policy would therefore involve improving the collection and use of wood and food crop waste, which already account for 10% of the world's energy production. Last in line comes artificial photosynthesis, which is often described as an energy source that competes with photovoltaic energy. The term 'artificial photosynthesis' is devoid of any technical meaning. What it really comes down to is communication. However, it does seem possible to imitate certain components of the photosynthetic apparatus, such as those involved in decomposing water into hydrogen and oxygen.

    This Baseline Risk Assessment report is the second volume in a set of three volumes for operable Unit 1 (OU-1). The companion documents contain the Remedial Investigation and the Feasibility Study. Operable Unit 1 (OU-1) is one of several groups of hazardous waste sites located at Eielson Air Force Base (AFB) near Fairbanks, Alaska. The operable units at Eielson are typically characterized by petroleum, oil, lubricant/solvent contamination, and by the presence of organics floating at the water table. In 1989 and 1990, firms under contract to the Air Force conducted field studies to gather information about the extent of chemical contamination in soil, groundwater, and soil air pore space (soil gas) at the site. This report documents the results of a baseline risk assessment, which uses the 1989 and 1991 site characterization database to quantify the potential human health risk associated with past Base industrial activities in the vicinity of OU-1. Background data collected in 1992 were also used in the preparation of this report

    Full text: The effect of increased fuel oxygen potential on fuel behaviour has been studied by fabricating and irradiating urania fuel with an average O/U ratio of 2.05. The fuel was fabricated by re-sintering standard urania pellets in a controlled oxygen potential environment and irradiated in a segmented rod bundle in a U.S. BWR. Preirradiation ceramographic characterization of the pellets revealed the well-known Widmanstaetten precipitation of U-409 platelets in the UO 2 matrix. The high O/U fuel pellets were clad in Zircaloy-2 and irradiated to over 20 GWd/MT. Ramp tests were performed in a test reactor and detailed postirradiation examinations of both ramped and nonramped rods have been performed. The cladding inner surface condition, fission gas release and swelling behavior of high O/U fuel have been characterized and compared with standard UO 2 pellets. Although fuel microstructural features in ramp-tested high O/U fuel showed evidence of higher fuel temperatures and/or enhanced transport processes, fission gas release to the fuel rod free space was less than for similarly tested standard UO 2 fuel. However, fuel swelling and cladding strains were significantly greater. In spite of high cladding strains, PCI crack propagation was inhibited in the high O/U fuel I rods. Evidence is presented that the crystallographically oriented etch features often noted in peripheral regions of high burnup fuels are not an indication of higher oxides of uranium. (author)

    Description of an experiment that was conducted, comparing LED lamps and SON-T (high pressure sodium) lamps. In climate rooms with LED (96% red sodium lamps) or SON-T lamps (without daylight), chrysanthemums were cultivated at two light intensities. Although the air temperature was the same in both treatments, the leaf temperature was clearly higher in the case of SON-T as a result of heat radiation. In the case of LED a more round leaves were observed. Plants cultivated under SON-T light developed closed crops much quicker and required a shorter reaction time (10 to 14 days at high and low light intensity). Yet, the harvest weight of the branches was the same. The net leaf photosynthesis was lower in chrysanthemums cultivated under LED lighting compared to plants cultivated under SON-T lighting. This is probably due to long-term cultivation under a spectrum of almost exclusively red light. The differences between SON-T and LED with regard to light color and heat radiation have significant consequences for growth and development. [Dutch] Een experiment is uitgevoerd om LED lampen en SON-T (hogedruk natriumlampen) lampen te vergelijken. In klimaatkamers met LED (96% rood en 4% blauw) of SON-T lampen (zonder daglichttoetreding) werden chrysanten geteeld bij 2 lichtintensiteiten. Hoewel de luchttemperatuur identiek was bij beide behandelingen was de bladtemperatuur duidelijk hoger bij SON-T als gevolg van warmtestraling. Onder LED belichting werd meer 'bol blad' waargenomen. Planten geteeld onder SON-T belichting ontwikkelden sneller een gesloten gewas en hadden een kortere reactietijd (10 tot 14 dagen bij hoge en lage lichtintensiteit). Maar het oogstgewicht van de takken was gelijk. De netto actuele bladfotosynthese was lager bij chrysanten geteeld onder LED belichting vergeleken met planten geteeld onder SON-T belichting. Dit is waarschijnlijk toe te schrijven aan langdurige teelt onder een spectrum met vrijwel alleen rood licht. De verschillen tussen SON-T

La réponse à cette question varie selon la nature des nutriments (vitamines, minéraux, acides gras poly-insaturés indispensables des graisses, acides aminés indispensables des protéines, et aussi de l’espèce considérée. Le problème est de rechercher l’impact réel des formulations des rations utilisées dans les élevages sur la valeur nutritionnelle des produits (viandes, lait et laitages, fromages et œufs, etc., et donc leur influence sur la santé du consommateur, évidemment dans un sens favorable. Les acides gras poly-insaturés oméga-3 (ω3 bénéficient de deux grands axes de valorisation. Le premier réside dans leur importance quantitative et leurs rôles dans le cadre de la mise en place et du maintien de divers organes, le cerveau au premier chef. Le second se trouve dans la prévention de diverses pathologies, les maladies cardio-vasculaires occupant une place prépondérante \\; avec, depuis peu, les maladies neuro-psychiatriques, stress, dépression et démence. Compte tenu des implications en termes de maladies, cardio-cérébro-vasculaires entre autres, le contrôle de la nature des acides gras constitutifs des graisses représente donc un enjeu considérable en ce qui concerne les viandes issues d’animaux terrestres, maritimes et aériens, du lait, des laitages, fromages et des œufs. Car la qualité des graisses données en nourriture animale détermine fondamentalement la valeur nutritionnelle des aliments qui en sont dérivés, pour la consommation humaine.

Dans cet article, nous analysons les données canadiennes de l’enquête sur le milieu de travail et les employés (EMTE de Statistique Canada. Nous nous demandons surtout si les milieux syndiqués sont mieux pourvus que les autres, si les hommes et les femmes disposent des mêmes mesures et si la situation s’est améliorée au fil des ans. Nous avons réalisé une analyse selon le sexe, selon que le milieu de travail est syndiqué ou non, et nous avons aussi fait une analyse comparative des données de 2002 et 2005 pour voir si la situation s’améliorait. Nous constatons que la situation est ambigüe pour ce qui est de la syndicalisation et de l’analyse selon le genre, certaines mesures étant plus accessibles que d’autres dans un cas ou l’autre et que la situation n’a pas beaucoup évolué dans le temps.Work-life and work-family issues have been high on the agenda over recent years. In this paper, we wanted to see if the situation had gotten better over recent years and analysed the Workplace and Employment Survey (WES of Statistics Canada. We ask whether unionized sectors are better off than non-unionized sector, if women and men have access to the same measures and if the measures offered have increased between 2002 and 2005. We see that the situation is ambiguous, in the sense that unionized sectors do not systematically have better measures, the gendered situation is also mixed and the percentage of workplaces offering measures has not systematically increased either.

    Full Text Available Cet article explore comment Margaret Atwood, dans La Voleuse d’hommes (The Robber Bride, 1993, élargit l’éventail des possibilités existantes pour concevoir l’identité nationale anglo-canadienne. Il se concentre sur la façon dont le roman réaborde et reformule certaines des questions sur l’identité canadienne qui sont posées avec insistance dans les premiers récits de fiction et essais critiques d’Atwood. L’article s’intéresse, en particulier, à la manière dont les récits d’évolution personnelle s’entrecroisent avec les discours sur l’identité féminine et canadienne dans La Voleuse d’hommes. Il s’agit d’examiner comment les trajectoires d’évolution personnelle explorées dans le roman attirent l’attention sur la relation complexe entre narration et identité, et d’expliquer comment progrès et évolution, dans les romans, sont influencés ou déterminés par un positionnement politique identitaire nationaliste spécifiquement féministe et canadien.

    Full Text Available Narrar é, segundo Benjamim, uma forma de intercambiar experiências, e se direcionarmos nosso olhar para o sujeito dessa narrativa, o teremos em duas funções: ora como narrador mestre, ora como narrador aprendiz. Contar estórias é um instrumento útil para evitar o esquecimento e para provocar uma abertura de espaço para a criação. O presente artigo apresenta uma das inúmeras possíveis leituras sobre as estratégias utilizadas por Mia Couto, em Terra sonâmbula, na criação de sujeitos que narram, que contam estórias. Uma busca por esses narradores em trânsito, narradores flutuantes ou nômades. Sujeitos em constante ir e vir, transitando e destransitando entre mundos aparentemente paradoxais, mas que se encontram separados por uma tênue linha, que, a qualquer momento, pode fazer com que mestre e aprendiz troquem de campo e função, ou até mesmo exerçam ambas. Os dois aprendem estórias novas e contam estórias antigas em um ir-evir espaço-temporal. O comportamento desses narradores é marcado por viagens e mutações ininterruptas. Constituinte de uma literatura atravessada por elementos insólitos, em um trabalho minucioso com a linguagem e em constante diálogo com a tradição moçambicana, esse comportamento tornase referencial para a compreensão da história política e cultural do país.Palavras-chave: Narrador; Benjamin; Hibridismo; Oratura; Identidade.

    L’objet de notre analyse dialogique et co-énonciative concerne la forme prise par la relation entre un père et son fi ls au cours d’échanges verbaux. Dans cette dimension relationnelle, nous avons cherché plus particulièrement à éclairer le statut d’énonciateur que chacun octroie à lui-même et à l’autre. Les images qu’un père et un fi ls ont l’un de l’autre et les places qu’ils occupent dans le dialogue sont en partie déterminées par leur statut de père et d’enfant. Ces places ne confi gurent pas un mode relationnel homogène. Au contraire, cet extrait de corpus est frappant par la grande diversité d’attitudes adoptées par le père avec son enfant: tour à tour il lui donne des ordres, des permissions, le réconforte, joue avec lui, lui propose des défi s ou rivalise avec lui. Daniel peut entrer dans le jeu proposé par son père ou s’y opposer, se laisser guider ou refuser, mais aussi être à l’initiative par des demandes ou des jeux. C’est cette diversité que nous tentons de mettre au jour, sachant que certaines séquences se caractérisent plus particulièrement par des décalages entre les interlocuteurs, alors que d’autres conduisent à des ajustements. Si la diversité qui caractérise cet extrait ne saurait être étendue comme caractérisant toute interaction père/enfant, l’analyse qui en est faite peut servir de repère pour l’étude de nouvelles interactions parent/enfant.

    2012-01-01

    Full Text Available Dans ce roman-énigme, les héritages rompus et à transmettre sont d’abord celui des générations, surtout entre la mère et la fille, mais plus globalement celui du passé de l’humanité, les deux étant évoqués sous le signe de la rupture, de la perte et de l’oubli, d’où la nécessité d’un travail de transmission qui obsède les personnages du roman. C’est dans un « nous » à la fois énigmatique et indéterminé que se confondent le passé, le présent et le futur, la vie et la mort, la fiction et le réel, et la mémoire comme héritage rompu mais à restaurer. Qu’il s’agisse d’une mère et d’une fille disparue, des ruines du passé et du présent, ou du désir d’un Descartes agonissant de revoir sa fille décédée, le roman ne cesse de souligner la continuité du passé, du présent et de l’avenir. Et au fond de tout, il y a, comme toujours chez Brossard, la centralité de l’écriture et de la fiction comme première modalité de la transmission des héritages. L’expérimentation formelle, ici présente surtout dans la structure narrative du roman, est intimement liée à cette volonté de transmission : loin de bafouer l’héritage du passé philosophique, intellectuel et littéraire, l’inscription de cet héritage dans des formes nouvelles et souvent difficiles dans leur nouveauté donne à ce passé une forme et un sens nouveaux. In this enigmatic novel, the characters are obsessed with a series of interrupted lines of filiation and heritage that they seek to restore: at first between generations, especially between mother and daughter, and then more globally those of humanity’s past. Both personal and universal heritages are figured as rupture, loss and forgetting, fuelling the characters’ obsessive need to re-establish means of transmitting the past. An enigmatic and indeterminate “we” englobes the past, present and future, life and death, fiction and reality, and the memory of the

Celle de la rupture avec toute idée de foyer et celle du refus d’appartenance à la terre natale, cette terre allemande traversée par une frontière le long de laquelle ils vont voyager, et qui les renvoie à chaque instant aux traumatismes de l’Histoire.

Au fil du temps questionne le paysage : il s’agit d’en décoller un à un les mythes qui le recouvrent. L’image alors n’est plus surface mais volume à traverser, à lacérer et découvrir ce qui est tissé dans le paysage. La démarche de Wenders est alors proche de celle d’un de ses contemporains : Anselm Kiefer. Le paysage allemand provoque le rejet parce qu’il y a là toujours plus que le visible : des strates et des strates de culpabilité que le mythe - et c’est sa fonction - a recouvert. Et qu’il s’agira ici, de soulever. Le choix du nomadisme, c’est celui d’un état de l’humanité antérieur à l’idée de patrie. Et c’est aussi celui de la solitude, comme prix à payer à ce refus d’appartenance et à cette mise à jour des mythes.

  4. Deux types de prédication, avec ou sans sujet: quelques illustrations colombiennes

    Directory of Open Access Journals (Sweden)

    1994-01-01

    Full Text Available Toutes les langues ne suivent pas dans leurs énoncés-phrases la division morpho-syntaxique Sujet / Prédicat. Plutôt que d’organiser le contenu de l’énoncé à partir d’une des entités dont on parle, certaines langues partent de ce qui est dit de ces entités, que cela soit appelé prédicat ou relation prédicative ou fonction prédicative, etc... Cette différente perspective se manifeste alors en un schéma de construction qu’on peut appeler “schéma holophrastique”, distinct du schéma “subjectal” ou schéma sujet / prédicat. L’article cherche à mettre à l’épreuve l’intérêt de cette distinction de schémas en en montrant l’usage dans quelques langues amazoniennes dont certaines sont présentées dans ce recueil. On voit que l’opposition entre schémas prédicatifs renvoie à une dimension qui doit être maintenue distincte de l’aspect ou de la voix, même si ces trois dimensions s’entrecroisent constamment. PREDICACIÓN CON SUJETO, PREDICACIÓN SIN SUJETO: EJEMPLOS COLOMBIANOS. No todas las lenguas siguen en sus oraciones la división morfosintáctica Sujeto vs. Predicado. En vez de organizar el contenido de la oración a partir de una de las entidades de las cuales se está hablando, algunas lenguas prefieren partir de lo que se dice de estas entidades, llámese predicado, relación predicativa, función predicativa, etc... Esta diferencia de punto de partida o de perspectiva se manifiesta en un esquema de construcción que llamamos “esquema holofrástico”, bien diferente del esquema sujeto/predicado llamado también “esquema subjetal”. Este artículo trata de poner a prueba el interés de esta oposición de esquemas mostrando su uso en algunas de las lenguas amazónicas, algunas de las cuales hacen parte de este compendio. Se ve por ejemplo que los esquemas predicativos remiten a una dimensión semántica distinta de la del aspecto o de la de la voz aún cuando estas tres dimensiones se entrecruzan

    Full Text Available La Côte d’Ivoire est le plus grand théâtre des migrations cacaoyères en Afrique sub-saharienne, depuis le Sahel et les régions de savane vers les forêts humides du golfe de Guinée. Dans tout le sud-ouest de la Côte d’Ivoire, se côtoient trois grands groupes de populations, les autochtones, les migrants d’originaires du centre du pays, et les migrants venus du Burkina Faso, ayant construit des modèles alimentaires spécifiques avant de se rencontrer. L’objectif est d’identifier les évolutions depuis leur rencontre dans les forêts du sud-ouest, puis d’en expliquer les déterminants. Les données collectées auprès de 110 planteurs, par questionnaires et interviews, sont limitées à la composante alimentaire des céréales, tubercules, banane plantain. Le résultat le plus important est une conversion partielle des régimes alimentaires des migrants vers le riz, longtemps l’alimentation de base des autochtones. Au cours de la même période de 30 ans, les autochtones suivent un chemin opposé, réduisant leur consommation de riz, abandonnant presque la production. Pour expliquer cette énigme sociologique, les thèses néo-malthusiennes appliquées à la Côte d’Ivoire, un temps contestées, sont remises à l’ordre du jour, teintées d’innovations boserupiennes. À la croisée des changements écologiques, économiques et sociaux, la raréfaction des terres, la disparition des forêts au cours du déroulement du cycle du cacao, l’accès différencié au travail, jouent un rôle décisif dans ces changements alimentaires, via des bouleversements dans les systèmes de production et les rapports sociaux.The Ivory Coast is the largest space for cocoa migrations in sub-Saharan Africa, extending from the Sahel and savannah regions to the rainforests of the Gulf of Guinea. In the southwest of Ivory Coast, three major population groups live side by side: natives, migrants coming from the central region of the country

    Full Text Available En Afrique du Nord, de nombreux aquifères sont surexploités, principalement du fait d’une agriculture irriguée intensive. Cependant, les politiques publiques qui ont cherché à réguler cet usage se sont montrées jusqu’à maintenant peu efficaces, du fait du manque de moyens et parce que les agriculteurs les considèrent comme peu légitimes. L’article analyse un cas de gestion collective de l’usage des eaux souterraines par les agriculteurs eux-mêmes, dans le cadre d’une association au Sud de la Tunisie. Dans la zone de Bsissi Oued El Akarit, l’administration multipliait dans les années 1990 les procédures de contrôle des puits, conduisant à de nombreux conflits. En 1999, les agriculteurs et l’administration se sont mis d’accord pour qu’un groupement de développement agricole soit créé spécifiquement pour contrôler les puits et forages dans cette zone. Depuis, le groupement a effectivement réussi à mettre en oeuvre un tel contrôle, mais reste toujours fragile financièrement car il ne s’auto-finance pas. Le processus de concertation qui a conduit à ce dispositif de gestion a réussi grâce à : i la posture de l’administration, à la fois ferme en matière d’application des lois en vigueurs, et ouverte à la concertation avec les agriculteurs, et ii aux compétences et à la légitimité des leaders du groupement. Cette expérience montre que, dans certains cas, les agriculteurs peuvent devenir partie prenante d’une cogestion des eaux souterraines pour un usage durable de cette ressource.

    Full Text Available Des procédés par plasmas alternatifs au procédé Claus sont proposés pour produire de l'hydrogène et récupérer du soufre à partir des gaz contenant une forte teneur en H2S. Quand la teneur en H2S est moins importante, des techniques plasma peuvent également être utiles pour assister certains étages du procédé classique Claus ou réaliser ce procédé pour des gaz non conventionnels. Les tests allant jusqu'à l'échelle industrielle sont menés dans divers réacteurs à plasmas et les résultats encourageants rapportés de la littérature et de la recherche propre laissent envisager des prochaines applications. Plasma assisted processes are proposed to act as an alternative to the Claus process in order to recover hydrogen and sulphur from high H2S gases. For less concentrated gases plasma techniques may also be inserted into classical Claus plant or may allow treatment of non conventional gases. Up to industrial scale tests are performed using different plasma reactors. The literature-based results as well as our own ones make the future applications quite optimistic.

    Full Text Available Kinship-related prohibitions such as the “in-law” avoidance are a defining feature of the nomadic foraging way of life of the Semang, northern Aslian speakers of peninsular Malaysia. With the stress of the recent Islamic assimilation policy and the changing base of subsistence, however, some Kensiw, a Semang group in Kedah, are feeling that the rules against cəmam or “improper sexual behaviour between relatives” may be contrary to the maintenance of their identity and moving toward a more inclusive identity of the peninsular-wide “Orang Asli”.Les interdictions liées à la parenté comme celle concernant les parents par alliance sont un trait caractéristique du mode de vie des Semang, des locuteurs septentrionaux d’une langue asli de la péninsule malaise. Toutefois, avec le stress récent dû à la politique d’islamisation et le changement de leur base alimentaire, quelques Kensiw, un groupe de Semang de Kedah, ont le sentiment que les règles s’opposant au cəmam ou « comportement sexuel impropre entre parents » pourrait être contraire au maintien de leur identité et sont en train de se rapprocher d’une identité plus inclusive de l’ensemble des « Orang Asli » de la péninsule.

    Des enregistrements continus d'activité locomotrice ont été effectués sur des souris mâles isolées des lignées Balb/c et C57bl/6, vivant en cages d'élevage ou en milieu semi- naturel. Les résultats montrent que les différences entre ces deux situations ne sont pas perçues de la même façon par les animaux des deux lign'ees: alors qu'en cages d'élevage les souris des deux lignées experiment la même quantité totale d'activaté, en milieu semi-naturel les souris Balb/c sont plus actives que les C57bl/6. En outre, l≐s différences observées entre les lignées pour la repartition de l'activité au cours du nycthèmere s'inversent lorsque l'on passe d'une situation à l'autre. L'étude de la variabilité fait aparaître une dispersion plus grande des performances dans la lignée C57bl/6 en cages d'élevage, alors qu'en milieu semi-naturel la dispersion est plus chez Bal/c.

    Ces dernières décennies, des activités significatives dans le monde étaient dirigées autour du contrôle actif. Le but de ces recherches était essentiellement d'améliorer les performances, la fiabilité et la sécurité des systèmes. Notamment dans le cas des structures soumises à des vibrations aléatoires. D'importants travaux ont été consacré à l'utilisation des “matériaux intelligents” comme capteurs et actionneurs. Cette article propose l'analyse de la fiabilité des systèmes mécaniques en étudiant les pannes des actionneurs ou des capteurs. L'effet de ces pannes sur la stabilité et la performance du système y est démontré. Les méthodologies de conception y sont rappelées. Des exemples numériques sont fournis à travers le contrôle d'un panneau sous chargement dynamique pour illustrer la méthode proposée.

    The United Kingdom Atomic Energy Authority operates establishments in locations ranging from the South of England to the North coast of Scotland. The functions of these establishments include the production and processing of nuclear fuels, the production of electricity and isotopes for commercial sale, the development of new types of reactors and the conduct of research in all the associated fields. The Authority therefore has a wide variety of wastes to deal with and they arise in a number of different places. The main high-activity wastes, both liquid and solid, are stored in special tanks and containers, while the low-activity large-volume liquid wastes are released in carefully controlled amounts to the sea or to rivers. Low-and medium- activity solid wastes are buried in selected areas where there will be no interference with water supplies, or sunk on to the sea bed. The paper summarizes the methods in use and gives typical quantities of liquid and solid waste arising annually for disposal by the various methods.

L' Atomic Energy Authority doit donc proceder, en plusieurs points du territoire, a l'elimination de toute une serie de dechets radioactifs d'origines diverses. Les principaux dechets, liquides et solides, a radioactivite elevee sont enfermes dans des reservoirs et recipients speciaux, tandis que les volumineux dechets liquides a faible radioactivite sont evacues, par quantites soigneusement controlees, dans la mer ou les cours d'eau.

    A review of the waste-disposal research and development carried out in the United States of America is given. The major research effort concerns the conversion of high-level liquid wastes into solids. At Hanford and Oak Ridge low-level wastes are disposed to the ground in pits, cribs and lagoons. Geochemical studies related to waste disposal are conducted at Hanford, Oak Ridge and the University of North Carolina. Experiments with soil columns ate described ; these are more effective for the decontamination of waste streams than either cribs or pits. The most suitable exchange materials for the soil columns are found to be vermiculite supported by rock phosphate and the latter supported by graded gravel. The progress of research work on the possibility of injecting radioactive liquid wastes into porous formations through deep wells and disposing of radioactive wastes in impermeable formations by hydraulic fracturing is outlined.

    An accurate estimation of the alpha-activity of a nuclear waste package is necessary to select the best mode of storage. The main purpose of this work is to develop a non-destructive active method, based on the fission process and allowing the identification of actinides ({sup 235}U, {sup 238}U, {sup 239}Pu). These three elements are the main alpha emitters contained inside a package. Our technique is based on the detection of delayed gammas emitted by fission products. These latter are created by irradiation with the help of a neutron or photon beam. Performances of this method have been investigated after an Active Photon or Neutron Interrogation (INA or IPA). Three main objectives were fixed in the framework of this thesis. First, we measured many yields of photofission products to compensate the lack of data in the literature. Then, we studied experimental performances of this method to identify a given actinide ({sup 239}Pu in fission, {sup 235}U in photofission) present in an irradiated mixture. Finally, we assessed the application of this technique on different mock-up packages for both types of interrogation (118 l mock-up package containing EVA in fission, 220 l mock-up package with a wall of concrete in photofission).

Dans la plupart des cas, ce sont les moyens stylistiques qui assurent la mémorisation du slogan et ainsi produisent un effet sur le consommateur. Dans ce contexte, il serait intéressant de savoir si ces moyens ont changé depuis l'époque soviétique. Pour cela, il faut identifier les tropes employés aux deux grandes périodes étudiées (contemporaine et soviétique, voir quels sont les plus fréquents pour chacune d'elles, et pour quelle(s raison(s, pour comprendre au final ce qui pourrait expliquer la fidélité à certains tropes et le recours à de nouvelles figures dans la période récente. Les hypothèses émises dans le présent article se basent sur un corpus de slogans assez important et ne cessant d'augmenter qui inclut les slogans soviétiques du début du XXème siècle, principalement créés lors de la Nouvelle Politique Economique, les slogans des années 30, période de croissance industrielle, et les slogans qui accompagnaient les affiches publicitaires de la période après la guerre, quand, par exemple, V. TRUXACOV, travaillant dans le réseau du Magasin Central, a créé de nombreuses affiches pour des biens de consommations tels que tissus, aspirateurs, téléviseurs, etc. Ce corpus contient également les quelques slogans de la période de stagnation économique sous le règne de L.

    Uranium oxide samples are dissolved in hot concentrated H 3 PO 4 - H 2 SO 4 mixture and the solution diluted with 1M H 2 SO 4 . One aliquot of such solution (A) is used to record the first voltamogram which gives the U(VI) content. To a second aliquot HNO 3 and H 2 O 2 is added to oxidise uranium to the hexavalent state (B) and the second voltamogram is recorded from 0.0 to 0.4 V X SCE. The O:U ratio in the original sample is calculated by the expression: O/U = 2.000 + [U (VI) soln.A/% U(VI) soln. B]. The method provides an accurate means for determining O to U ratios in high-purity uranium dioxide, fuel pellets and a variety of oxides prepared for developmental work on ceramic fuel materials.

    Using positive semidefinite supOU (superposition of Ornstein-Uhlenbeck type) processes to describe the volatility, we introduce a multivariate stochastic volatility model for financial data which is capable of modelling long range dependence effects. The finiteness of moments and the second order...... structure of the volatility, the log returns, as well as their "squares" are discussed in detail. Moreover, we give several examples in which long memory effects occur and study how the model as well as the simple Ornstein-Uhlenbeck type stochastic volatility model behave under linear transformations....... In particular, the models are shown to be preserved under invertible linear transformations. Finally, we discuss how (sup)OU stochastic volatility models can be combined with a factor modelling approach....

    Tritium is a dangerous gas for man and the maximum admissible doses in the atmosphere are sufficiently low for the dosage to be fairly difficult. We have developed an apparatus for measuring selectively the contamination of air by this gas when it is alone or when it is associated with other gaseous contaminants. The differential apparatus using two ionization chambers makes it possible to eliminate a parasitic {gamma} radiation field. In a few particular cases, the presence of the radio-active gas has been studied. From the practical point of view, the use of these chambers made of stainless steel makes for easier use since the problems connected with wall adsorption have been satisfactorily resolved. The method can be applied without restriction and very easily to the dosage of traces tritium in air or in the form of tritiated water or tritiated steam in the atmosphere. (author) [French] Le tritium est un gaz dangereux pour l'homme et les concentrations maximales admissibles dans l'atmosphere sont suffisamment basses pour que le dosage soit delicat. Nous avons etudie et realise un appareil qui permet de mesurer selectivement la contamination de l'air par ce gaz lorsqu'il est seul ou lorsqu'il est associe a d'autres agents gazeux contaminants. Le montage differentiel a deux chambres d'ionisation permet d'eliminer un champ de rayonnement {beta} parasite. Dans certains cas particuliers, la presence du gaz radioactif a ete etudiee. Sur le plan pratique, l'utilisation des chambres en acier inoxydable facilite les applications car les problemes d'adsorption aux parois ont ete bien resolus. La methode peut s'appliquer sans restriction et tres pratiquement au dosage des traces de tritium dans l'air ou encore sous forme d'eau tritiee ou de vapeur d'eau tritiee dans l'atmosphere. (auteur)

    Full Text Available Pour mener leurs études, les morphologues, et, singulièrement parmi eux, ceux qui traitent du lexique construit, sont pris entre deux tensions : utiliser les données issues des dictionnaires, réputées fiables parce que passées au travers du crible de l’institutionnalisation, ou se fonder sur des données authentiques, produites dans des situations écologiques. Bien qu’inspirant encore de la défiance, le Web devient alors la ressource par excellence. Les ressources numérisées telles que les archives de journaux ou les bases de données de textes littéraires constituent un moyen terme entre ces deux pratiques : elles permettent d’effectuer des recherches basées sur l’usage, tout en offrant la garantie d’une certaine tenue linguistique de la part des scripteurs, la plupart du temps identifiables. Dans cette communication, nous nous demanderons si les dictionnaires méritent la confiance que continuent de leur octroyer les morphologues ou, plus exactement, si une morphologie qui puise ses données dans les seuls dictionnaires peut encore avoir cours au 21e siècle. Pour engager cette discussion, nous commencerons par poser la question de l’existence, pour un lexème construit. Nous exposerons ensuite ce que constitue une morphologie basée sur l’usage, puis donnerons un aperçu des types de recherches que permettent de réaliser les ressources non dictionnairiques. La conclusion sera que, si les dictionnaires continuent d'avoir droit de cité dans la panoplie du morphologue, une morphologie uniquement basée sur les données qu'ils contiennent passerait outre de nombreuses recherches, plus fructueuses les unes que les autres.

  11. Implementation of Enhanced Attenuation at the DOE Mound Site OU-1 Landfill: Accelerating Progress and Reducing Costs

    At the US Department of Energy (DOE), Office of Legacy Management, Mound, Ohio, Site, chlorinated organic contaminants (cVOCs) originating from the former solid-waste landfill have impacted groundwater in Operable Unit 1 (OU-1). The baseline groundwater remedy was groundwater pump and treat (P&T). Since the source materials have been removed from the landfill, the Mound core team, which consists of DOE, US Environmental Protection Agency (US EPA), Ohio EPA, and other stakeholders, is assessing the feasibility of switching from the active P&T remedy to a passive attenuation-based remedy. Toward this end, an enhanced attenuation (EA) strategy based on the creation of structured geochemical zones was developed. This EA strategy addresses the residual areas of elevated cVOCs in soil and groundwater while minimizing the rebound of groundwater concentrations above regulatory targets (e.g., maximum contaminant levels [MCLs]) and avoiding plume expansion while the P&T system is turned off. The EA strategy has improved confidence and reduced risk on the OU-1 groundwater transition path to monitored natural attenuation (MNA). To better evaluate the EA strategy, DOE is conducting a field demonstration to evaluate the use of edible oils to enhance the natural attenuation processes. The field demonstration is designed to determine whether structured geochemical zones can be established that expedite the attenuation of cVOCs in the OU-1 groundwater. The EA approach at OU-1 was designed based on “structured geochemical zones” and relies on groundwater flow through a succession of anaerobic and aerobic zones. The anaerobic zones stimulate relatively rapid degradation of the original solvent source compounds (e.g., cVOCs such as tetrachloroethene [PCE] and trichloroethene [TCE]). The surrounding aerobic areas encourage relatively rapid degradation of daughter products (such as dichloroethene [DCE] and vinyl chloride [VC]) as well as enhanced cometabolism of TCE resulting from

Conception Un sondage à choix multiples envoyé par courriel et autoadministré par des SMSE et des urgentologues. La validité du contenu du sondage a fait l’objet d’une évaluation. Contexte Canada. Participants Le sondage a été complété entre mai et juillet 2012 par des SMSE qui ont réussi l’examen menant au diplôme de l’Académie canadienne de la médecine du sport et de l’exercice et des urgentologues qui n’avaient pas ce diplôme. Principaux paramètres à l’étude La connaissance et l’identification des sources d’information sur la prise en charge des commotions, l’utilisation des stratégies de diagnostic de la commotion et l’utilisation d’une terminologie courante et cohérente dans l’explication des stratégies de repos aux patients après une CDS. Résultats Le taux de réponse était de 28 % (305 sur 1085). Les taux de réponse par les SMSE et les urgentologues se situaient respectivement à 41 % (147 sur 360) et 22 % (158 sur 725). Parmi les répondants, 41 % des urgentologues et 3 % des SMSE n’étaient pas au courant de l’existence de déclarations consensuelles sur la commotion dans le sport; 74 % des SMSE utilisaient « habituellement ou toujours » la version 2 de l’Outil d’évaluation de la commotion dans le sport (SCAT2), tandis que 88 % des urgentologues n’utilisaient jamais le SCAT2. Aucune réponse uniforme n’a été documentée à la question visant à connaître les meilleurs modes de repos cognitif.

    The most important carriers of radioactive contamination of man are the whole of foodstuffs and not only ingested water or inhaled air. That is the reason why, in accordance with the spirit of the recent recommendations of the ICRP, it is proposed to substitute the idea of maximum levels of contamination of water to the MPC. In the case of aquatic food chains (aquatic organisms and irrigated foodstuffs), the knowledge of the ingested quantities and of the concentration factors food/water permit to determinate these maximum levels, or to find out a linear relation between the maximum levels in the case of two primary carriers of contamination (continental and sea waters). The notion of critical food-consumption, critical radioelements and formula of waste disposal are considered in the same way, taking care to attach the greatest possible importance to local situations. (authors) [French] Les vecteurs essentiels de la contamination radioactive de l'homme sont les aliments dans leur ensemble, et non seulement l'eau ingeree ou l'air inhale. C'est pourquoi, en accord avec l'esprit des recentes recommandations de la C.I.P.R., il est propose de substituer aux CMA la notion de niveaux limites de contamination des eaux. Dans le cas des chaines alimentaires aquatiques (organismes aquatiques et aliments irrigues), la connaissance des quantites ingerees et celle des facteurs de concentration aliments/eau permettent de determiner ces niveaux limites dans le cas de deux vecteurs primaires de contamination (eaux continentales et eaux oceaniques). Les notions de regime alimentaire critique, de radioelement critique et de formule de rejets sont envisagees, dans le meme esprit, avec le souci de tenir compte le plus possible des situations locales.

    Various methods which have been considered for processing and treating radioactive wastes of both low and high level are discussed. Low-Level Wastes-Gases are diluted and discharged to the atmosphere through stacks or are filtered through highly retentive filters. Typical installations are described. Incineration of combustible wastes has been examined and descriptions and operating data are given. Baling is often a useful adjunct to a solids collection system. A variety of processes for liquid wastes have been studied. Typical systems are described and operating data given. High-Level Wastes-Gases are sometimes vented directly through stacks but more often some treatment is required. The treatment takes the form of chemical scrubbing, removal of iodine on silver reactors, rare-gas removal and filtration. Highly contaminated solids may require decontamination in place before they can be removed. High-level liquid wastes represent the largest single waste-disposal problem facing the industry at the present time. This problem includes reduction in the volume of the waste originally produced by process changes or changing the process; concentration of the produced waste or reduction to solids by one of several methods including concentration, use of Portland cement, adsorption on clays or other natural materials, and calcination. The technical and economic problems associated with temporary storage are considered. It may become necessary to do waste processing at only a few carefully selected sites. Estimates are made of the amounts that might be involved in transport and of the equipment needed. The attendant hazards and costs are considered.

The spectra are processed in measurement batches, making up a homogeneous study, which comprise standards and samples. This highly versatile program may either ensure the processing of a great number of daily analyses, or be used pending development of radiochemical methods. The feeding of data has been simplified as much as possible. On the contrary, at the outlet, the numerical or graphical controls, error computations, and the printing of results in clear and legible form have been multiplied.

    Oued Fez (one of the Sebou River tributaries - Morocco) allowed us to study and quantify the effect of the lack of wastewater treatment on surface water quality in semi-arid hydrological context. The analysis is based on field data collected from June 2009 to December 2011. Concentration and load patterns of nitrogen, phosphorus and chromium (used in the processing of leather) are compared in stable hydrological conditions during low flow and high flow periods in an eight-location sampling network. The Oued Fez and the Sebou River are characterised by severe pollution downstream from the city of Fez, particularly TN (mainly NH4 and Norg), TP (mainly Ppart) and TCr. The most polluted sites are those directly under the influence of domestic and industrial waste water inputs, particularly tannery effluents. Obviously, the concentrations measured at these locations are above all environmental quality standards. Pollutant loads are very heavy in the Sebou River and can contaminate the river course for kilometres. Moreover, as the water of the Sebou River is used for the irrigation of vegetables, serious problems of public health could arise. A better understanding of contaminant dynamics and self-purifying processes in these rivers will help implement actions and steps aimed at improving water quality in the Sebou River, which is the primary water supply source in Morocco and is used for agricultural and industrials purposes as well as for drinking water.

    The paper outlines the present practices in the control and treatment of radioactive wastes at Harwell. The large-volume, low-level active liquid effluent is treated by phosphate coagulation methods and, eventually, discharged to the River Thames. The medium-level wastes are segregated and undergo a two-stage chemical treatment followed by passage through columns of Vermiculite. The latter process has been found to be effective in removing radoicaesium, which is not dealt with efficiently by the precipitation methods used. Liquid wastes with a high- activity content are stored and a new plant, incorporating chemical treatment, ion exchange and evaporation, is being installed. The chemical sludges formed in the treatment processes are dumped at sea after de-watering by filtration. The contaminated solid waste is either stored or disposed of at sea. It is important to reduce the volume as much as possible and the methods employed include pressure baling, melting and incineration of combustible matter. Small quantities of activity are discharged to the atmosphere through exhaust stacks.

    Full Text Available O panoptismo - um conceito fundamental para a compreensão da formação e do funcionamento das sociedades disciplinares ocidentais a partir dos séculos XVII-XVIII - apareceu em meados dos anos 70 nas análises empreendidas por Michel Foucault, em Vigiar e Punir, de um dispositivo carcerário setecentista então pouco estudado - o panopticum de Jeremy Bentham. Este artigo procede a uma releitura da teoria foucaultiana do panoptismo em que a crítica do dispositivo panóptico é retomada a partir do filme A Laranja Mecânica de Stanley Kubrick, enfatizando metodologicamente a relevância da ficção-científica, como um gênero,  na elaboração teórica das passagens e processos de transição que podemos observar entre as já conhecidas e estudadas formas disciplinares de sociedade e uma possível, ou suposta, sociedade porvir do controle.

    Soil salinisation is a phenomenon considered to be a real threat to natural resources in semi-arid climates. The phenomenon is controlled by soil (texture, depth, slope etc.), anthropogenic factors (drainage system, irrigation, crops types, etc.), and climate factors. This study was conducted in the watershed of Oued El Abid in the region of Beni Mellal-Khenifra, aimed at localising saline soil using remote sensing and a regression model. The spectral indices were extracted from Landsat imagery (30 m resolution). A linear correlation of electrical conductivity, which was calculated based on soil samples (ECs), and the values extracted based on spectral bands showed a high accuracy with an R2 (Root square) of 0.80. This study proposes a new spectral salinity index using Landsat bands B1 and B4. This hydro-chemical and statistical study, based on a yearlong survey, showed a moderate amount of salinity, which threatens dam water quality. The results present an improved ability to use remote sensing and regression model integration to detect soil salinity with high accuracy and low cost, and permit intervention at an early stage of salinisation.

    Full Text Available O que é qualidade de vida e o quanto podemos medir dela? Pensa-se em qualidade de vida como resultado das políticas públicas e desenvolvimento de uma sociedade, onde os determinantes socioambientais se manifestam como atributo de seus atores. Ao mesmo tempo, pode-se entender esta idéia no outro extremo da análise, a partir da percepção de uma população protagonista de sua realidade, do que vem a ser qualidade de vida segundo ela mesma. Partindo-se dos aspectos conceituais de qualidade de vida, passou-se a adotar os conceitos de diferenciais intra-urbanos como a melhor maneira de caracterizar os desajustes e as desigualdades urbanas, para assim entender os componentes da iniqüidade desse meio. A primeira iniciativa marcou a utilização do método genebrino ou distancial. Hoje, já na segunda versão desse método, incorporou-se a esse contexto outras metodologias que possibilitam maior consistência de análise para ampliar a validade dessas medições. Soma-se a esse contexto, a análise de cluster e o Sistema de Informações Geográficas, tanto no cenário intra-urbano, quanto intermunicipal.

    2011-01-01

    In this study, waste management concept, waste management system, biomass and bio-waste resources, waste classification, and waste management methods have been reviewed. Waste management is the collection, transport, processing, recycling or disposal, and monitoring of waste materials. A typical waste management system comprises collection, transportation, pre-treatment, processing, and final abatement of residues. The waste management system consists of the whole set of activities related to handling, treating, disposing or recycling the waste materials. General classification of wastes is difficult. Some of the most common sources of wastes are as follows: domestic wastes, commercial wastes, ashes, animal wastes, biomedical wastes, construction wastes, industrial solid wastes, sewer, biodegradable wastes, non-biodegradable wastes, and hazardous wastes.

    The following report presents test descriptions and analysis results for multiple, stress level slug tests that were performed at selected test/depth intervals within three Operable Unit (OU) ZP-1 wells: 299-W11-43 (C4694/Well H), 299-W15-50 (C4302/Well E), and 299-W18-16 (C4303/Well D). These wells are located within south-central region of the Hanford Site 200-West Area (Figure 1.1). The test intervals were characterized as the individual boreholes were advanced to their final drill depths. The primary objective of the hydrologic tests was to provide information pertaining to the areal variability and vertical distribution of hydraulic conductivity with depth at these locations within the OU ZP-1 area. This type of characterization information is important for predicting/simulating contaminant migration (i.e., numerical flow/transport modeling) and designing proper monitor well strategies for OU and Waste Management Area locations.

    Full Text Available Neste texto, pretendo analisar a tese principal do ensaio “A verdade sublime” de Philippe Lacoue-Labarthe, a qual poderia ser formulada do seguinte modo: a verdade sublime é o Ereignis, esse é o fundamento a partir do qual se desenvolveu uma dificílima operação que consistiu em modificar a tradição do sublime sempre apresentado negativamente naquilo que Lacoue-Labarthe chamou de "compreensão afirmativa do sublime ou da grande arte". O autor estabelece uma astuciosa aliança entre o que há de mais radical no pensamento de Heidegger e o sublime, tratado de maneira bastante polêmica, como a principal teoria da arte de Kant. Dessa articulação fundamental, pode-se concluir que ele não está apenas à procura de uma “Estética” (sequer de uma “Teoria da Arte” sublime, mas, em busca de algo que é muito mais ambicioso, a saber: de um pensamento do sublime. Portanto, na minha opinião, o ensaio lacouelabarthiano constitui, por um lado, uma referência indispensável não só a quem quer que pretenda estudar a tradição do sublime, mas, por outro, compreender o pensamento heideggeriano sobre a arte e sua tentativa de encontrar uma determinação mais essencial e, sobretudo, ousaria dizer, mais política da arte.

Characterizing residential waste is faced with the problem that many residences already divert some waste away from the official collection systems, for example performing home composting of vegetable waste and garden waste, having their bundled newspaper picked up by the scouts...... twice a year or bringing their used furniture to the flea markets organized by charity clubs. Thus, much of the data available on residential waste represents collected waste and not necessarily all generated waste. The latter can only be characterized by careful studies directly at the source......, but such studies are very expensive if fair representation of both spatial and temporal variations should be obtained. In addition, onsite studies may affect the waste generation in the residence because of the increased focus on the issue. Residential waste is defined in different ways in different countries...

Tectonic structures (e.g., synsedimentary faults played a relevant role in the ore emplacement. The dolomitic ore-related host-rock levels are characterized by the presence of kaolinite enrichment in clay levels in amounts directly related to the proportion of the clay minerals. The latter is evidenced by correlation between kaolinite and sulphide contents, suggesting that the installation of kaolinite and mineralisations would result from the same hydrothermal fluid.[Français] Dans les séries sédimentaires carbonatées d’Ali ou Daoud (Haut Atlas Central, les minéralisations à Zn, Pb et Fe en amas stratiformes forment les faciès de remplissage des karsts d’une plateforme carbonatée bajocienne.

Dans les niveaux dolomitiques encaissants des minéralisations, les assemblages argileux sont caractérisés par la présence de kaolinite dont la teneur varie parallèlement avec celle du minerai.

    Full Text Available Environmental issues began to be introduced more frequently in corporate business. As for the supply chain, Green Supply Chain Management (GSCM emerges as a new approach to corporate responsibility towards the environment. This article aims to analyze the diffusion of the GSCM concept and practices in the Brazilian scenario. To do that, we conducted interviews with experts on the subject of the supply chain in the area of Management in Brazil. The results show that the reasons for the slow development of the concept may relate to characteristics of the domestic market, corporate focus on internal aspects, lack of strict legislation, and low consumer pressure. Experts notice, however, good prospects for the future of discussions on the subject in the Country, due to the National Solid Waste Policy, pressure from the international market, and the search for environmental certification. This study sought to foster further discussions on GSCM in Brazil.

  14. Waste incineration

    International Nuclear Information System (INIS)

    Rumplmayr, A.; Sammer, G.

    2001-01-01

    Waste incineration can be defined as the thermal conversion processing of solid waste by chemical oxidation. The types of wastes range from solid household waste and infectious hospital waste through to toxic solid, liquid and gaseous chemical wastes. End products include hot incineration gases, composed primarily of nitrogen, carbon dioxide, water vapor and to a smaller extend of non-combustible residue (ash) and air pollutants (e. g. NO x ). Energy can be recovered by heat exchange from the hot incineration gases, thus lowering fossil fuel consumption that in turn can reduce emissions of greenhouse gases. Burning of solid waste can fulfil up to four distinctive objectives (Pera, 2000): 1. Volume reduction: volume reduction of about 90 %, weight reduction of about 70 %; 2. Stabilization of waste: oxidation of organic input; 3. Recovery of energy from waste; 4. Sanitization of waste: destruction of pathogens. Waste incineration is not a means to make waste disappear. It does entail emissions into air as well as water and soil. The generated solid residues are the topic of this task force. Unlike other industrial processes discussed in this platform, waste incineration is not a production process, and is therefore not generating by-products, only residues. Residues that are isolated from e. g. flue gas, are concentrated in another place and form (e. g. air pollution control residues). Hence, there are generally two groups of residues that have to be taken into consideration: residues generated in the actual incineration process and others generated in the flue gas cleaning system. Should waste incineration finally gain public acceptance, it will be necessary to find consistent regulations for both sorts of residues. In some countries waste incineration is seen as the best option for the treatment of waste, whereas in other countries it is seen very negative. (author)

Lorsque des députés de circonscriptions « celtiques » (en Écosse ou au pays de Galles arrivent à influencer le résultat de votes sur des affaires exclusivement anglaises, certains députés d’Angleterre, à Westminster, ne peuvent que se sentir désarmés face au manque de dispositions constitutionnelles garantissant un statut particulier pour ce territoire. Dès lors, de cette « question anglaise » (« English Question », naîtra toute une nouvelle mouvance autonomiste entièrement dédiée à l’obtention d’un Parlement anglais.Devolution at the end of the 1990s has led to numerous consequences and transformations in British politics. The traditional and centralised Westminster system has been turned upside down, and many studies have been carried out on the various aspects of this new “devolved Britain”.Yet, few have paid attention to the English case. However, the constitutional asymmetry thus created has indeed also affected England. When Celtic MPs succeed to influence the outcome of votes on exclusively English matters, one can realise that there is no such thing as an English government. Therefore, some English MPs have felt the need to ask for an option of “English Votes on English Laws”. This article tries to demonstrate that a feeling of “resentment” emerges from this situation and leads to the birth of a new “English” nationalism, entirely dedicated to obtaining an English Parliament.

Tout en reconnaissant la complicité d’une grosse partie des politiciens africains dans le partage et saccage de leur continent et dans les guerres qui les traversent, l’article veut contrecarrer le discours de Sarkozy par les paroles de trois représentants les plus significatifs du panafricanisme: Kwame Nkrumah, Patrice Lumumba et Thomas Sankara. Ces trois hommes politiques ont dénoncé avec fermeté les intérêts économiques néocoloniaux qui empêchent une véritable indépendance de l’Afrique. Il s’agit en outre de souligner que l’oblitération et le refoulement des souffrances provoquées par la colonisation au sein des pays de l’occident sont l’indice de l’acceptation par la majorité de leurs populations de l’état des choses en Afrique, qui est ainsi, en quelque sorte, naturalisé. Cette acceptation tacite constitue une condition fondamentale de la reproduction quotidienne du dispositif pacificateur de domination au sein du monde développé. Les maux de l’Afrique trouvent leur cause alors moins dans une attitude de l’homme africain que dans un système de domination économique et idéologique assuré par les institutions internationales tels que l’ONU, la Banque mondiale ou le FMI.

    The previous system which consisted in the use of metallic reservoirs placed in a concrete-lined pit gave rise to certain incidents due to corrosion or overflowing followed by contamination with serious consequences. The new system presented consists essentially of a standard 3 m{sup 3} reservoir of stainless steel which is fixed in a concrete-lined well, is tubed with stainless steel. Each reservoir has a standard lid on which are placed all the accessory devices, themselves standardized. The new reservoirs offer thus a great degree of security, and are interchangeable; the wells are easy to decontaminate and it is possible to work in a well without any danger of the personnel being irradiated by neighbouring reservoirs. (author) [French] L'ancien systeme de cuves metalliques disposees dans une fosse betonnee a donne lieu a des incidents par corrosion ou debordements suivis de contamination ayant de grosses consequences.

Chaque cuve comporte un couvercle standard sur lequel sont rassembles tous les dispositifs annexes standardises eux aussi. Les nouvelles cuves sont donc sures, interchangeables, les puits sont faciles a decontaminer et le travail dans un puits est possible sans crainte d'irradiation du personnel par les cuves voisines.

    The policy concerning radioactive wastes studied by all Atomic Centres has led to various procedures which, while apparently numerous, come under a few standard headings. Whether the wastes are in the liquid or solid state their management depends on their physical and chemical nature. The procedure adopted is governed by three general principles: - determination of the most economical means possible of storage and processing by volume reduction; - conversion to a solid compact form; - complete acceptance of the accepted standards at all places and all times. In this communication all the standard solutions adopted and used by the various Centres of the Commissariat a l'Energie Atomique will be examined bearing in mind the preceding remarks. Particular mention will be made of the following: - For liquids, physical, chemical and physico-chemical processing - For solids, decontamination, volume reduction and long-term conditioning techniques. The different procedures for collecting and storing solid wastes before and after processing are also discussed. The paper ends with a brief review of the studies, both technical and economic, being pursued on this subject. (authors) [French] La gestion des dechets etudies par tous les Centres Atomiques a donne lieu a des solutions qui - bien que nombreuses en apparence - se ramenent a quelques solutions types, peu nombreuses.

    Full Text Available La transcription et l’étude des manuscrits préparatoires de Salammbô a permis de retracer la genèse du personnage féminin, en mettant en valeur son aventure personnelle. Les passages inédits, les marges et écritures interlinéaires apportent des éléments précieux pour construire le roman d’amour de l’héroïne, et lui donner une tonalité plus érotique, avant que Flaubert ne supprime, transforme ou masque habilement ces traces éphémères. Afin que les lignes soient plus nettes, ma recherche privilégie le point de vue de Salammbô, pour autant qu’on puisse connaître cette figure énigmatique. En laissant de côté, volontairement, les problèmes primordiaux du roman, la guerre historique de Carthage, la lutte mythique entre Tanit et Moloch, la grande Histoire et la mythologie, les batailles et les massacres, la lumière se concentre sur l’aventure sentimentale, absolument nécessaire dans un roman historique, l’auteur le sait. L’évocation du milieu social de la fille du suffète Hamilcar, l’analyse de son psychisme, de ses désirs, de ses rêves et de ses croyances apportent un éclairage sur sa vie de femme. L’examen d’un inédit comme les pages consacrées à la danseuse montre la volonté du romancier de créer un personnage séduisant et actif. Devant les guerriers a lieu l’« épiphanie », caractéristique des héros : le chant lyrique et la danse ésotérique en sont les signes manifestes. Après la rencontre, Salammbô et Mâtho, en proie au désir amoureux, se cherchent, se fuient et rêvent l’un de l’autre. Un inédit rapporte le songe de la jeune femme. Des expériences qui allient plaisir et souffrances, l’union mystique avec le serpent, la « baisade » contribuent à son éducation sentimentale mais la déception finale, l’échec du désir, est la vraie révélation.The transcription and study of Salammbô’s preparatory manuscripts enable us to retrace the genesis of the feminine

    The report gives a review of waste incineration in Sweden today, including environmental and legal aspects. 21 incinerator plants are in use, producing heat to district heating network and, to a minor part, electric power. In 1991 1.31 Mton household waste and 0.35 Mton industrial waste were incinerated producing 4.4 Twh of energy. In a few cities 30-40 percent of the district heat comes from waste incineration. The theoretical and practical potentials for energy production in Sweden are estimated to 7 respective 5 TWh for household waste and 9 respective 5-6 TWh for industrial waste. Landfill gas is extracted at about 35 sites, with a yearly production of 0.3 TWh which corresponds to 3-5 percent of the potentially recoverable quantity. (8 refs., 2 figs., 13 tabs.)

    1990-01-01

    Each year, nuclear power plants, businesses, hospitals, and universities generate more than 1 million cubic feet of hardware, rags, paper, liquid waste, and protective clothing that have been contaminated with radioactivity. While most of this waste has been disposed of in facilities in Nevada, South Carolina, and Washington state, recent legislation made the states responsible - either individually, or through groups of states called compacts - for developing new disposal facilities. This paper discusses the states' progress and problems in meeting facility development milestones in the law, federal and state efforts to resolve issues related to mixed waste (low-level waste that also contains hazardous chemicals) and waste with very low levels of radioactivity, and the Department of Energy's progress in discharging the federal government's responsibility under the law to manage the most hazardous low-level waste

    Full Text Available L’indétermination qui entoure le terme de « Palestine », provoquée notamment par la disparition de son référent géographique depuis la création de l’État d’Israël, a généré une multitude de représentations concurrentes qui ont fait de ce terme un écran. Ce dernier révèle la complexité des enjeux géopolitiques qui s’y cristallisent, mais rend extrêmement difficile la formulation d’un récit et d’une représentation palestiniens propres. Travailler sur la production cinématographique palestinienne revient à s’interroger sur la manière dont les cinéastes composent avec les multiples représentations de leur terre et de son peuple telles qu’elles sont produites par l’Autre, qu’il soit Israélien ou occidental.

    It is being realized that if environmental quality is to be improved the amount of waste generated by man has to be substantially reduced. There are two ways this can be achieved. First, by conserving materials and energy, and sacrificing economic growth, a solution that is completely unacceptable because it would mean some form of rationing, mass unemployment, and collapse of society as it is known. The second way to reduce the volume of waste is by planned recycling, re-use, and recovery. Already the reclamation industry recovers, processes, and turns back for re-use many products used by industry and thereby reduces the UK's import bill for raw materials. In the book, the author sets out the various ways materials may be recovered from industrial and municipal wastes. The broad technology of waste management is covered and attention is focused on man's new resources lying buried in the mountains of industrial wastes, the emissions from stocks, the effluents and sludges that turn rivers into open sewers, and municipal dumps in seventeen chapters. The final chapter lists terms and concepts used in waste technology, organizations concerned with waste management, and sources of information about recycling waste. (MCW)

    Current planning for the management of radioactive wastes, with some emphasis on plutonium contaminated wastes, includes the provision of re-positories from which the waste can be safely removed to permanent disposal. A number of possibilities for permanent disposal are under investigation with the most favorable, at the present time, apparently disposal in a stable geological formation. However, final choice cannot be made until all studies are completed and a pilot phase demonstrates the adequacy of the chosen method. The radioactive wastes which result from all portions of the fuel cycle could comprise an important source of exposure to the public if permitted to do so. The objectives of the AEC waste management program are to provide methods of treating, handling and storing these wastes so that this exposure will not occur. This paper is intended to describe some of the problems and current progress of waste management programs, with emphasis on plutonium-contaminated wastes. Since the technology in this field is advancing at a rapid pace, the descriptions given can be regarded only as a snapshot at one point in time. (author)

    This chapter present a brief overview of the current situation of siting radioactive wastes. This is followed by an overview of various psychological approaches attempting to analyse public reactions to nuclear facilities. It will be argued that public reactions to nuclear waste factilities must be seen in the context of more general attitudes toward nuclear energy. The latter are not only based upon perceptions of the health and environmental risks but are built on values, and sets of attributes which need not be similar to the representations o the experts and policy-makers. The issue of siting nuclear waste facilities is also embedded in a wider moral and political domain. This is illustrated by the importance of equity issues in siting radioactive wastes. In the last section, the implications of the present line of argument for risk communication and public participation in decisions about siting radioactive wastes will be briefly discussed.

    Radioactive waste, as a unavoidable remnant from the use of radioactive substances and nuclear technology. It is potentially hazardous to health and must therefore be managed to protect humans and the environment. The main bulk of radioactive waste must be permanently disposed in engineered repositories. Appropriate safety standards for repository design and construction are required along with the development and implementation of appropriate technologies for the design, construction, operation and closure of the waste disposal systems. As backend of the fuel cycle, resolving the issue of waste disposal is often considered as a prerequisite to the (further) development of nuclear energy programmes. Waste disposal is therefore an essential part of the waste management strategy that contributes largely to build confidence and helps decision-making when appropriately managed. The International Atomic Energy Agency provides assistance to Member States to enable safe and secure disposal of RW related to the development of national RWM strategies, including planning and long-term project management, the organisation of international peer-reviews for research and demonstration programmes, the improvement of the long-term safety of existing Near Surface Disposal facilities including capacity extension, the selection of potential candidate sites for different waste types and disposal options, the characterisation of potential host formations for waste facilities and the conduct of preliminary safety assessment, the establishment and transfer of suitable technologies for the management of RW, the development of technological solutions for some specific waste, the building of confidence through training courses, scientific visits and fellowships, the provision of training, expertise, software or hardware, and laboratory equipment, and the assessment of waste management costs and the provision of advice on cost minimisation aspects

    The literature shows substantial differences in occupational exposures between men and women, both between and within occupations, but remains very sparse on whether interventions are tailored to gender differences in the workplace. Our objective was to determine whether gender differences are taken into account when designing prevention interventions. This study is part of a project on the evaluation of interventions implemented in the framework of the "Healthy Enterprise" standard in Quebec organizations. Three sets of quantitative and qualitative data were collected in seven organizations and triangulated. Our results show that in the process of elaborating and implementing activities, the main objectives were to reach a maximum number of workers and meet the needs identified in a health and risk diagnosis. Activities were not tailored to the needs of specific subgroups of employees, such as gender or age. Not distinguishing men's and women's situations in this diagnosis may play a role in intervention design.

    The presence of tritium in tritium-burning devices to be built for large scale research on thermonuclear fusion poses many problems especially in terms of occupational and environmental safety. One of these problems derives from the production of tritiated wastes in gaseous, liquid and solid forms. All these wastes need to be adequately processed and conditioned to minimize tritium releases to an acceptably low occupational and environmental level and consequently to protect workers and the public against the risks of unacceptable doses from exposure to tritium. Since all experimental thermonuclear fusion devices of the Tokomak type to be built and operated in the near future as well as all experimental activities undertaken in tritium laboratories like ETHEL will generate tritiated wastes, current strategies and practices to be applied for the routine management of these wastes need to be defined. Adequate background information is provided through an exhaustive literature survey. In this frame alternative tritiated waste management options so far investigated or currently applied to this end in Europe, USA and Canada have been assessed. The relevance of tritium in waste containing gamma-emitters, originated by the neutron activation of structural materials is assessed in relation to potential final disposal options. Particular importance has been attached to the tritium retention efficiency achievable by the various waste immobilization options. 19 refs., 2 figs., 1 tab

    A scoping study has been undertaken to determine the state-of-the-art of waste segregation technology as applied to the management of low-level waste (LLW). Present-day waste segregation practices were surveyed through a review of the recent literature and by means of personal interviews with personnel at selected facilities. Among the nuclear establishments surveyed were Department of Energy (DOE) laboratories and plants, nuclear fuel cycle plants, public and private laboratories, institutions, industrial plants, and DOE and commercially operated shallow land burial sites. These survey data were used to analyze the relationship between waste segregation practices and waste treatment/disposal processes, to assess the developmental needs for improved segregation technology, and to evaluate the costs and benefits associated with the implementation of waste segregation controls. This task was planned for completion in FY 1981. It should be noted that LLW management practices are now undergoing rapid change such that the technology and requirements for waste segregation in the near future may differ significantly from those of the present day. 8 figures

Notre corpus est composé de 91 fils de discussion publiés sur le forum du réseau Pédago2.0. Ce réseau professionnel rassemble près de 500 professeurs en histoire et géographie. La plupart d'entre eux sont fortement investis dans l'association Les Clionautes et peuvent être qualifiés d'enseignants innovants. L'analyse de données quantitatives ainsi que des messages publiés sur le forum Pédago2.0, nous ont permis de mettre en lumière différents modes implicites de fonctionnement que nous présentons dans cet article.Over the past decade, teachers have created and animated corporate networks based on technologies of the Web 2.0 outside the strict institutional hierarchy. Yet little studied, many of these online networks are now welcomed with great success. The aim of this article is to provide a framework enabling us to identify significant aspects of teachers' behavior when they talk on newsgroups hosted through these networks. We tested our framework on a corpus of 91 threads of discussion published on the Pédago2.0 newsgroup. This professional network gathers nearly 500 French history and geography teachers. Most of these teachers are deeply implicated in an association, Les Clionautes, and can be described as innovating teachers. Quantitative data and posted messages analysis allowed us to highlight some implicit functioning rules, which we are presenting in this article.

    Comparison of determination O/U ratio by using potentiometric and gravimetric methods has been done. Those methods are simple, economical and having high precision and accuracy. Determination O/U ratio for UO 2 powder using potentiometric is carried out by adopting the davies-gray method. This technique is based on the redox reaction of uranium species such as U(IV) and U(VI). In gravimetric method,the UO 2 power as a sample is calcined at temperature of 900 C, and the weight of the sample is measured after calcination process. The t-student test show that there are no different result significantly between those methods. However, for low concentration in the sample the potentiometric method has a highed precision and accuracy compare to the gravimetric method. O/U ratio obtained is 2.00768 ± 0,00170 for potentiometric method 2.01089 ± 0,02395 for gravimetric method

    1989-01-01

    This paper reviews the Department of Energy's management of underground single-shell waste storage tanks at its Hanford, Washington, site. The tanks contain highly radioactive and nonradioactive hazardous liquid and solid wastes from nuclear materials production. Hundreds of thousands of gallons of these wastes have leaked, contaminating the soil, and a small amount of leaked waste has reached the groundwater. DOE does not collect sufficient data to adequately trace the migration of the leaks through the soil, and studies predicting the eventual environmental impact of tank leaks do not provide convincing support for DOE's conclusion that the impact will be low or nonexistent. DOE can do more to minimize the environmental risks associated with leaks. To reduce the environmental impact of past leaks, DOE may be able to install better ground covering over the tanks to reduce the volume of precipitation that drains through the soil and carries contaminants toward groundwater

    Managing radioactive wastes used to be a peripheral activity for the French atomic energy commission (Cea). Over the past 40 years, it has become a full-fledged phase in the fuel cycle of producing electricity from the atom. In 2005, the national radioactive waste management agency (ANDRA) presented to the government a comprehensive overview of the results drawn from 15 years of research. This landmark report has received recognition beyond France's borders. By broadening this agency's powers, an act of 28 June 2006 acknowledges the progress made and the quality of the results. It also sets an objective for the coming years: work out solutions for managing all forms of radioactive wastes. The possibility of recovering wastes packages from the disposal site must be assured as it was asked by the government in 1998. The next step will be the official demand for the creation of a geological disposal site in 2016

    Full Text Available L’Éducation sentimentale a donné lieu à des lectures divergentes, non seulement au XXe siècle, entre la vieille critique psychologisante et idéalisatrice et la critique textuelle éteignant les élans de la chair dans la stricte littérarité, mais dès la publication du roman : d’aucuns (rares y sont sensibles à la subtile et amère ironie qui décape le désir et en révèle l’essentielle inactivité, quand d’autres, plus nombreux, y stigmatisent la « concupiscence » généralisée. Le heurt de ces interprétations révèle la profonde ambiguïté d’un désir que le roman choisit de ne jamais fixer. L’examen de l’excipit est intéressant dans la mesure où s’y trouve activée cette indécision, selon des modalités particulières. Sur sa limite, en effet, le désir amoureux, que le roman a préalablement travaillé selon les deux axes antagonistes du platonisme ou de la chair, exacerbe et fond ces aspects. Se construit alors, fugacement, une représentation du désir échappant à l’alternative entre satisfaction et insatisfaction, pour apparaître comme énergie et tension configuratrice trouvant une résolution.- En somme, « n’importe », puisque, in extremis, quelque chose a lieu.The Éducation sentimentale has led to conflicting interpretations, not only in the 20th Century, between the old psychological and idealistic criticism and textual criticism limited to strict literalness, but also when the novel was published.  Some, but very few, were sensible to the subtle and bitter irony that strips desire and reveals its essential inactivity, while others, the majority, stigmatized its widely spread covetousness.  The clash of these interpretations reveals the deep ambiguity of a desire that the novel chooses never to pin down.  A study of the pleading is interesting in so far as it is where this indecision is activated. On this boundary the amorous desire is shown to be strangely disturbing compared with

    Full Text Available Originating in the western world at the end of the 13th century, treatises about poisoning aim to protect patients against poisons or to heal the poisoned. They must be considered as medical writings belonging to scholasticism. But the subject of toxicatio leads the authors to speak about antidotes that seem, at fi rst sight, far from the world of learned medicine because they are linked with “marvels of nature” or with popular culture. After listing those things mentioned by doctors, the paper will try to show why and how they were intellectually integrated in the scientia venenorum.[fr] Éclos en Occident à la fin du XIIIe siècle, les traités des poisons visent à protéger ou soigner les patients des périls ou des effets du poison. Ils se rangent parmi les écritures médicales scolastiques. Mais le domaine de la toxicatio conduit les auteurs à traiter d’antidotes à première vue éloignés des sphères de la médecine savante, soit qu’ils se rattachent aux “merveilles de la nature”, soit qu’ils proviennent de la culture vulgaire. Après avoir inventorié ces anti-poisons mentionnés par les docteurs, l’article s’attachera à montrer pourquoi et comment ils sont intellectuellement intégrés à la scientia venenorum.

Encore peu d'études, notamment dans le domaine francophone, ont examiné l'influence de ces outils sur l'apprentissage des langues, même si certains résultats d'ordre ergonomique commencent à prendre assise. Dans les cédéroms d'apprentissage de langue étrangère, les escamots sont essentiellement des escamots d'aide, destinés à assister l'apprenant dans la réalisation de tâches d'apprentissage ou de navigation. En ce sens, l'appréciation subjective de ces outils par les apprenants constitue un facteur non négligeable dans le processus d'utilisation du didacticiel. Après avoir examiné la littérature concernée, nous avons donc réalisé une première enquête préliminaire, en favorisant l'aspect quantitatif, avec un échantillon d'apprenants vaste et non homogène.

Nesse sentido, recorrendo a uma entrevista semiestruturada, o presente estudo procurou, através da descrição detalhada das experiências pessoais de dois participantes, compreender os seus valores, as suas crenças, as suas representações, as suas atitudes e opiniões, assim como as suas referências normativas. Entre outras conclusões, ressaltamos que, para além de as experiências de dupla discriminação serem relatadas de forma central pelos participantes, verifica-se, de igual modo, a emergência de significados existenciais alternativos que lhes possibilitem alcançar as suas expectativas quanto à vivência da homossexualidade e da sexualidade.

    1988-01-01

    As required by the Nuclear Waste Policy Act of 1982, the Department of Energy is to annually determine whether the waste disposal fee will produce sufficient revenues to offset the total estimated costs of the waste disposal program. In its June 1987 assessment, DOE recommended that the fee remain unchanged even though its analysis showed that at an inflation rate of 4 percent the current fee would result in end-of-program deficits ranging from $21 billion to $76 billion in 2085. The 1988 assessment calls for reduced total costs because of program changes. Thus, DOE may be able to begin using a realistic inflation rate in determining fee adequacy in 1988 without proposing a major fee increase

    For low-level waste disposal in coastal waters the character of the biota and the eating habits of local human populations will determine the safe limits of contamination. In such a situation the sedimentary bottom populations win be important, since they will be exposed continuously, while planktonic and fish populations will drift through or enter the area of contamination sporadically. In the open ocean, on the other hand, planktonic populations are of prime importance, both as the food supply of pelagic edible species, and because they may be effective in transporting isotopes. Similar questions face biologists studying either sedentary or planktonic populations. These include the need to know the distribution and density of populations of various species, the rate of growth of the individuals and of the populations, the seasonal cycle of production and of abundance, the ability of various organisms to accumulate various elements, and the ways in which these elements are transported through the food web, to the bottom through sedimentation or vertically within the water column through migration and exchange. For each specific waste-disposal problem a survey of the local biota will be required, as will the subsequent monitoring of the operation.

    Full Text Available La philanthropie semble avoir en Asie suscité un net engouement ces dernières décennies. En Thaïlande toutefois, ces largesses financières à l’égard des œuvres du bouddhisme ou des fondations patronnées par la famille royale ne sont pas toujours l’illustration d’un total désintéressement. En effet, en contrepartie de cette générosité bien orientée, le donateur peut espérer recevoir – voire réclamer – une des multiples décorations officiellement attribuées par le souverain. Lorsque le donateur est une donatrice, certaines médailles donnent droit à des titres placés dorénavant devant le prénom qui ont pour effet de distinguer une nouvelle noblesse. Cette ferveur pour les décorations a pu entraîner dans le passé des phénomènes de corruption de la part de hauts responsables de monastères bouddhiques habilités à délivrer des certificats de donations. Au lieu de réelle philanthropie ou même d’évergétisme à la mode antique, c’est bien de course aux honneurs ou philotimie qu’il convient ici de parler.We can at times talk of a craze for philanthropy in Asia. However, in Thailand, that financial liberality for Buddhism charitable works or the plethora of foundations patronized by members of the royal family are not always a proof a perfect unselfishness. Actually, in return for this well connected generosity, the donator expects to receive—or even ask for—one of numerous decorations officially bestowed by the king. Even, in the case of the donator being a woman, some of these medals of higher ranks have for effect that therefore a special title is positioned ahead of the personal name just like if it was to create a new kind of nobility. In the past, that enthusiasm for royal decorations has generated cases of corruption by some high-level monastery hierarchy empowered for the delivery of donation certificates. Instead of true philanthropy or even antic style evergetism, we should talk here of

  13. Steppic environments at the end of the upper pleistocene in southern Tunisia (Oued el Akarit)

    Science.gov (United States)

    Brun, Annik; Guerin, Claude; Levy, Alain; Riser, Jean; Rognon, Pierre

    The cross section of the Oued el Akarit, 25 km North of Gabès, is of considerable importance for the paleoenvironmental reconstitution of South Tunisia at the end of the Upper Pleistocene. Grey or black silts and clays and greenish gray sands which overlap them, contain many paleontological remains: rodents, birds and Rhinoceros bones, Gasteropods, Foraminifera, Ostracoda and pollen. All these sedimentological, faunistic or botanical indications allow to consider that this area, between approximatively 35,000 and 22,000 yr. B.P., belonged to the steppe domaine. But this steppe was probably more dense and more diversified than the present-day steppe which receives 170 mm of rain (annual average). This conclusion is in good agreement with the other paleoenvironmental data from the Chott Djerid, the Matmata plateau or the Gulf of Gabès cores, areas situated at about 100 km to the West, the South or the East of the Oued el Akarit.

    Rhodobacter sphaeroides O.U.001 is a purple non-sulfur bacterium producing hydrogen under photoheterotrophic conditions. Hydrogen is produced by Mo-nitrogenase enzyme and substantial amount of H{sub 2} is reoxidized by a membrane-bound uptake hydrogenase in the wild type strain. To improve the hydrogen producing capacity of the cells, a suicide vector containing a gentamicin cassette in the hupSL genes was introduced into R. sphaeroiodes O.U.001 and the uptake hydrogenase genes were destroyed by site directed mutagenesis. The correct integration of the construct was confirmed by uptake hydrogenase activity measurement, PCR and subsequent sequence analysis. The wild type and the mutant cells showed similar growth patterns but the total volume of hydrogen gas evolved by the mutant was 20% higher than that of the wild type strain. This result demonstrated that the hydrogen produced by the nitrogenase was not consumed by uptake hydrogenase leading to higher hydrogen production. (author)

    We demonstrate deterministic generation of two distinct collective excitations in one atomic ensemble, and we realize the Hong-Ou-Mandel interference between them. Using Rydberg blockade we create single collective excitations in two different Zeeman levels, and we use stimulated Raman transitions to perform a beam-splitter operation between the excited atomic modes. By converting the atomic excitations into photons, the two-excitation interference is measured by photon coincidence detection with a visibility of 0.89(6). The Hong-Ou-Mandel interference witnesses an entangled NOON state of the collective atomic excitations, and we demonstrate its two times enhanced sensitivity to a magnetic field compared with a single excitation. Our work implements a minimal instance of boson sampling and paves the way for further multimode and multiexcitation studies with collective excitations of atomic ensembles.

  1. Celulares pagos por empregadores: “benefício” ou “malefício”?

    Directory of Open Access Journals (Sweden)

    Lúcia Cipriano

    Full Text Available Ao longo do século XX, os espaços e horários destinados ao trabalho eram isolados daqueles destinados à vida pessoal, familiar ou ao lazer. Na contemporaneidade, no entanto, tornou-se comum atender telefonemas de trabalho nos mais variados locais fora do horário de expediente e até mesmo nas férias. Uma das razões para esse novo tipo de comportamento é a concessão, pelos empregadores, de celulares com contas pagas aos seus funcionários. A presente pesquisa procurou investigar quais são as reações desses funcionários. Para tanto, foram conduzidas entrevistas de perguntas abertas com ocupantes de cargos de níveis gerenciais em empresas particulares do Estado do Rio de Janeiro. Foi possível constatar uma ambivalência generalizada entre os entrevistados. Por um lado, eles consideram tal prática um “benefício”, porque também podem usar o celular da empresa para assuntos pessoais, o que representa uma boa economia. Por outro lado, no entanto, se ressentem da invasão, não remunerada ou previamente acordada, de seu tempo livre. Alguns chegam mesmo a se referir a essa concessão como um “malefício”, ou, ainda mais radicalmente, como uma nova forma de escravidão.

    The Koeberg nuclear power station, planned to come on stream in 1984, is expected to save South Africa some six million t/annum of coal, and to contribute some 10 per cent of the country's electricity requirements. The use of nuclear energy will provide for growing national energy needs, and reduce high coal transport costs for power generation at the coast. In the long term, however, it gives rise to the controversial question of nuclear waste storage. The Atomic Energy Corporation of South Africa Ltd (AEC) recently announced the purchase of a site in Namaqualand (NW Cape) for the storage of low-level radioactive waste. The Nuclear Development Corporation of South Africa (Pty) Ltd, (NUCOR) will develop and operate the site. The South African Mining and Engineering Journal interviewed Dr P.D.

    A review is presented on the environmental behavior of radioactive wastes. The management of high-level wastes and waste disposal methods were discussed. Some topics included were ore processing, coagulation, absorption and ion exchange, fixation, ground disposal, flotation, evaporation, transmutation and extraterrestrial disposal. Reports were given of the 226 Ra, 224 Ra and tritium activity in hot springs, 90 Sr concentrations in the groundwater and in White Oak Creek, radionuclide content of algae, grasses and plankton, radionuclides in the Danube River, Hudson River, Pacific Ocean, Atlantic Ocean, Lake Michigan, Columbia River and other surface waters. Analysis showed that 239 Pu was scavenged from Lake Michigan water by phytoplankton and algae by a concentration factor of up to 10,000. Benthic invertebrates and fish showed higher 239 Pu concentrations than did their pelagic counterparts. Concentration factors are also given for 234 Th, 60 Co, Fe and Mr in marine organisms. Two models for predicting the impact of radioactivity in the food chain on man were mentioned. In an accidental release from a light-water power reactor to the ocean, the most important radionuclides discharged were found to be 90 Sr, 137 Cs, 239 Pu and activation products 65 Zr, 59 Fe, and 95 Zr

    DOE estimates that disposing of radioactive waste from civilian nuclear power plants and its defense-related nuclear facilities could eventually end up costing $32 billion. To pay for this, DOE collects fees from utilities on electricity generated by nuclear power plants and makes payments from its defense appropriation. This report states that unless careful attention is given to its financial condition, the nuclear waste program is susceptible to future shortfalls. Without a fee increase, the civilian-waste part of the program may already be underfunded by at least $2.4 billion (in discounted 1988 dollars). Also, DOE has not paid its share of cost-about $480 million-nor has it disclosed this liability in its financial records. Indexing the civilian fee to the inflation rate would address one major cost uncertainty. However, while DOE intends to do this at an appropriate time, it does not use a realistic rate of inflation as its most probable scenario in assessing whether that time has arrived

    There is an increasing need to couple environmental and economic considerations within waste management. Consumers and companies alike generate ever more waste. The waste-policy challenges of the future lie in decoupling growth in waste generation from growth in consumption, and in setting priorities for the waste management. This report discusses the criteria for deciding priorities for waste management methods, and questions the current principles of EU waste policies. The basis for the discussion is the so-called waste hierarchy which has dominated the waste policy in the EU since the mid-1970s. The waste hierarchy ranks possible methods of waste management. According to the waste hierarchy, the very best solution is to reduce the amount of waste. After that, reuse is preferred to recycling which, in turn, is preferred to incineration. Disposal at a landfill is the least favourable solution. (BA)

Les recherches portent sur deux types generaux: les depots salins et les formations permeables profondes. Dans les deux cas, on procede a des experiences en laboratoire pour etudier l'interaction des dechets en solution et des matieres constituant le terrain considere; pour les depots salins, une experience sur le terrain est en cours, dans laquelle on utilise des dechets simules de. haute activite, qui, en realite, ne sont pas radioactifs. II. Les structures assurant un isolement moyen doivent ralentir notablement la mobilite des dechets pour que ceux-ci aient le temps de se desintegrer au point de vue radioactif avant de venir en contact avec l'homme ou la chaine alimentaire. Comme exemple d'isolement moyen, on peut citer l'enfouissement a faible profondeur de dechets emballes et le deversement de dechets liquides en vrac dans des couloirs d'infiltration.

    Bennett, W.S.; Crisler, L.R.

    1981-01-01

    To ensure that all technology necessary for long term management of transuranic (TRU) wastes is available, the Department of Energy has established the Transuranic Waste Management Program. A principal focus of the program is development of waste forms that can accommodate the very diverse TRU waste inventory and meet geologic isolation criteria. The TRU Program is following two approaches. First, decontamination processes are being developed to allow removal of sufficient surface contamination to permit management of some of the waste as low level waste. The other approach is to develop processes which will allow immobilization by encapsulation of the solids or incorporate head end processes which will make the solids compatible with more typical waste form processes. The assessment of available data indicates that dewatered concretes, synthetic basalts, and borosilicate glass waste forms appear to be viable candidates for immobilization of large fractions of the TRU waste inventory in a geologic repository

    Full Text Available Doze ovinos com cânulas de rúmen foram empregados para comparar seis tratamentos, dispostos em um arranjo fatorial 2 x 3: cana de açúcar nas formas fresca (CAF ou ensilada (CAS x teores de uréia iguais a 0,0%, 0,5% e 1,0%. Foram estimadas: taxas de degradabilidade efetiva (DGE dos alimentos volumosos, concentrações de ácidos graxos voláteis(AGV e de nitrogênio amoniacal (N-NH3 e valores de pH do conteúdo do rúmen, além de concentrações de N-uréico no sangue. As taxas de DGE da matéria seca (MS mostraram-se semelhantes para CAF e CAS. A adição de teores crescentes de uréia às forragens resultou em diminuição linear da DGE da MS tanto da CAF como da CAS. No caso da CAS, a DGE da fibra em detergente neutro diminuiu linearmente com concentrações crescentes de uréia. Os valores de pH do conteúdo ruminal foram maiores para CAS em relação a CAF, mas não ocorreram diferenças devidas à adição de uréia. Os teores do conteúdo ruminal em total de AGV e os de ácido propiônico foram maiores para a CAF em relação a CAS; os de ácido acético, ao contrário, foram maiores para a CAS. Os teores de N-NH3 do conteúdo ruminal foram maiores para a CAS que para a CAF. Nos tratamentos com CAF e nos com CAS, as concentrações de N-NH3 no conteúdo ruminal e de N-uréico no sangue aumentaram linearmente com maiores adições de uréia. Concluiu-se que a adição de 0,5% e 1,0% uréia às forragens frescas ou ensiladas de cana-de-açucar não mostrou resultados satisfatórios e que CAF apresentou indícios de melhor qualidade nutricional que CAS.

    The effect of O/U ratio on chemical reactivity was investigated in a cesium-iodide/uranium/tungsten system at temperatures up to 2200 K. It was found that slight changes in the oxidation of the urania had a large effect on reactivity. Crushed fresh fuel samples showed little reaction with CsI; however, slightly hyperstoichiometric fuel showed considerable reaction. The tungsten participated in the reaction by removing excess oxygen from the urania, eventually leading to a cesium tungstate species that was analyzed by Fourier Transform Infrared (FTIR) and X-ray diffraction (XRD) techniques.

    In the treatment of wastes, such as liquid radioactive effluents, it is known to remove radionuclides by successive in situ precipitation of cobalt sulphide, an hydroxide, barium sulphate and a transition element ferrocyanide, followed by separation of the thereby decontaminated effluent. In this invention, use is made of precipitates such as obtained above in the treatment of further fresh liquid radioactive effluent, when it is found that the precipitates have additional capacity for extracting radionuclides. The resulting supernatant liquor may then be subjected to a further precipitation treatment such as above. Decontamination factors for radionuclides of Ce, Ru, Sr and Cs have been considerably enhanced. (author)

    The prime solution to the present energy crisis is the recovery of latent energy from waste materials, for solid waste contains recoverable energy and it merely needs to be released. The paper is concerned with classification of solid waste, energy content of waste, methods of solid waste disposal, and chemical processing of solid waste. Waste disposal must be performed in situ with energy recovery. Scarcity of available land, pollution problem, and unrecovered latent energy restrict the use of the land-filling method. Pyrolysis is an effective method for the energy recovery and disposal problems. Chemical processing is suitable for the separated cellulosic fraction of the waste material.

    Full Text Available Le traitement des eaux de raffinerie par le procédé des Iits bactériens constitue une solution intéressante. Néanmoins, il subsiste actuellement des problèmes pratiques d'exploitation, en particulier la tendance au colmatage des lits bactériens existants qui résulte d'un encrassement incontrôlé des garnissages en vrac. Après étude, il est confirmé que les hydrocarbures, les matières en suspension contenus dans l'effluent et une mauvaise évacuation de la biomasse sont à l'origine du problème. L'examen des possibilités de lutte contre ce phénomène permet de distinguer des mesures curatives et des mesure préventives. Les mesures curatives qui consistent à régénérer le garnissage par augmentation de la charge hydraulique, nettoyage chimique, ou nettoyage manuel ne donnent pas entière satisfaction. Parmi tes mesures préventives, l'une des méthodes consiset à réduire la charge polluante de l'effluent : les eaux usées phénolées sont dessalées, les eaux de désulfuration du gas oil (DGO et fluid cracking catalytic (FCC sont strippées, les soudes sont réinjectées dans le brut, les huiles récupérées juste en aval de leur rejet, les traitements primaires sont optimisés, notamment par installation de racleurs et de tambours oléophiles sur les séparateurs API et par un meilleur choix de floculants. Néanmoins, l'expérience montre que cette méthode ne permet que de retarder l'échéance du colmatage. Le meilleur moyen de lutte réside dans le choix du matériau de garnissage, ainsi que le montrent les essais pilotes comparatifs réalisés par l'Institut National de Recherche Chimique Appliquée (lRCHA et Compagnie Française de Raffinage (CFR. Ces essais, qui ont portés sur l'évolution de la densité du garnissage, les performances épuratoires et la qualité des boues montrent que le Cloisonyle, garnissage tubulaire, est probablement le matériau le mieux adapté.

This report has found that DOE's financial assistance budget request of $15 million for Nevada's fiscal year 1990 was not based on the amount the state requested but rather was derived by increasing Nevada's grant funds from the previous year in proportion to the increase that DOE requested for its own activities at the Nevada site.

Under such a program, the training and qualifications of DOE and contractor employees would be verified. This report reviews DOE's efforts to identify and resolve the implications of the Privacy Act for DOE's quality assurance program and how the delay in resolving Privacy Act issues may have affected preliminary work on the Yucca Mountain project

    Full Text Available La collecte et l’analyse de données ne constituent pas des phénomènes récents. Néanmoins, d’importants changements se sont produits dans ce domaine au cours des dernières décades, faisant de la surveillance un outil à part entière des institutions modernes. Cet article analyse la manière dont les technologies de surveillance comme la vidéosurveillance, les banques de données ou encore la cartographie de la criminalité entrent en interaction, au sein des institutions chargées de la lutte contre la délinquance, avec le monopole étatique de la violence légitime. L’étude empirique de deux services de police français (un service dédié à la police des transports ferroviaires et une unité d’enquête composée d’agents issus d’administrations différentes montre que ces technologies sont mises au service d’un ciblage de l’action de police sur des territoires ou des individus identifiés comme « à risque ». Elle tend à relativiser, dans le contexte français, l’hypothèse d’un mode de surveillance qui serait synonyme d’un adoucissement du contrôle social. Elle suggère que l’usage des technologies de surveillance peut aussi bien aider à la relégitimation de moyens de contrôle traditionnels à une époque où la discrétionnarité du travail policier est de plus en plus contestée.Data collection and analysis is not a recent phenomenon. However, major changes have occurred in recent decades and surveillance now appears as a general tool in modern institutions. This paper is concerned with analyzing the way surveillance technologies such as CCTV, databases, or crime mapping concretely interact with the State’s traditional monopoly of force in the institutions charged of crime control. The empirical study of two French police services (a transit police department and an inter-institutional detective squad reveals that these technologies are used by police managers to target high-risk territories and

Pour interroger la dynamique du temps choisi impulsée par les 35 heures, deux dimensions du temps de travail sont examinées : son contenant, à savoir les aspects externes, morphologiques ou géométriques tels que la durée et l’horaire de travail ; et son contenu, à savoir les aspects internes ou constitutifs se rapportant à la mise en œuvre de la force de travail. L’étude réalisée dans une caisse régionale d’assurance maladie montre une construction ambivalente du temps choisi : si les salariés ont gagné du pouvoir quant à la détermination de la durée de leur travail et la manière de l’aménager, ils n’ont plus la maîtrise du (temps de travail lui-même, à savoir l’organisation et le contenu de l’activité professionnelle.The main objective of this article is to see if shorter working time takes into account the wishes of salaried workers when setting up their schedules and if so, how and to what extent. To explore the dynamics of selected time as promoted by the 35-hour week, we examine two dimensions : the container of working time, i.e. its external, morphological or geometric aspects such as duration and schedule ; and its contents, i.e. the internal or structural aspects which concern the implementation of the workforce. The study was carried out in a local branch of the French public healthcare system and reveals that workers are ambivalent about selected time : though they gain some power in deciding how long they will work and how to manage their schedule, they have lost control over their actual working time, i.e. over the organization and content of their professional activity.

    Out of the legal poblems that are currently at issue, individual questions from four areas are dealt with: privatization of ultimate waste disposal; distribution of responsibilities for tasks in the field of waste disposal; harmonization and systematization of regulations; waste disposal - principles for making provisions for waste disposal - proof of having made provisions for waste disposal; financing and fees. A distinction has to be made between that which is legally and in particular constitutionally imperative or, as the case may be, permissible, and issues where there is room for political decision-making. Ultimately, the deliberations on the amendment are completely confined to the sphere of politics. (orig./HSCH) [de

Parmi les nombreux animaux endémiques de l’île, les lémuriens sont les plus emblématiques. Au sein de l’ordre des primates, ils sont l'un des groupes les plus diversifiés. Si leur origine reste mal connue, de nombreuses formes subfossiles éteintes sont attestées pour les derniers 26 000 ans ; les plus récentes datant d'il y a quelques siècles seulement. Ces animaux sont souvent mentionnés dans les récits anciens ou les légendes car leur taille a impressionné les premiers explorateurs et scientifiques.

Au-delà du drame humain qui a fait plus d’une centaine de morts et plus d’un millier de blessés, cette contestation s’est formulée autour d’une organisation anachronique : les aarch. Système sociopolitique ancien dont les dernières traces d’existence remontent à la fin du XIXe siècle, il a mobilisé dans et par la tribu reconfigurée selon les besoins contemporains. Cette utilisation d’une organisation sociale maghrébine a permis de une inscription dans le temps par la mémoire mobilisée par la tribu.En effet, dans une perspective politique, les aarch, pour contester le présent, ont mis en exergue des patrimoines historiques et mémoriels effacés par l’État nation algérien. Mobilisant ainsi l’histoire de la guerre de décolonisation, fondatrice de l’État indépendant, les aarch se sont directement attaqués au vouloir vivre ensemble, redéfinissant les bases constitutives de la nation. Cette dynamique mémorielle et historique a aussi permis aux militants et partisans de revisiter un passé plus lointain : crises au sein du mouvement nationaliste, mouvements sociaux post Indépendance, etc. Ce remaniement des mémoires, dont la culture et la langue restent les socles, a permis d’envisager des territoires culturels, identitaires dépassant les frontières stato-nationales.Si ces données sont celles du politique, des militants, les bases sociales du mouvement, qui a mobilisé jusqu’à 1,5 million de personnes, ont réutilisé ces outils de la contestation pour les transformer en sources du malaise socioéconomique contemporain.The riots that have bloodstained Kabylie in the spring of 2001 have raised different problematics.

    Most of our activities have always produced waste products of one sort or another. Huxley gives a humorous account of wastes throughout antiquity. So it should come as no surprise that some radioactive materials end up as waste products requiring management and disposal. Public perception of nuclear waste hazards places them much higher on the ''worry scale'' than is justified by the actual hazard involved. While the public perception of these hazards appears to revolve mostly around high-level wastes, there are several other categories of wastes that must also be controlled and managed. The major sources of radioactive wastes are discussed

    Lloyd, P.D.

    2001-01-01

    The Waste Dislodging and Conveyance System (WD and CS) and other components of the Tank Waste Retrieval System (TWRS) were developed to address the need for removal of hazardous wastes from underground storage tanks (USTs) in which radiation levels and access limitations make traditional waste retrieval methods impractical. Specifically, these systems were developed for cleanup of the Gunite and Associated Tanks (GAAT) Operable Unit (OU) at the Oak Ridge National Laboratory (ORNL). The WD and CS is comprised of a number of different components. The three primary hardware subsystems are the Hose Management System (HMS), the Confined Sluicing End-Effector (CSEE), and the Flow Control Equipment and Containment Box (FCE/CB). In addition, a Decontamination Spray Ring (DSR) and a control system were developed for the system. The WD and CS is not a stand-alone system; rather, it is designed for deployment with either a long-reach manipulator like the Modified Light Duty Utility Arm (MLDUA) or a remotely operated vehicle system such as the Houdinitrademark. The HMS was designed to act as a pipeline for the transfer of dislodged waste; as a hose-positioning and tether-management system; and as a housing for process equipment such as the water-powered jet pump that provides the necessary suction to vacuum slurried waste from the UST. The HMS was designed to facilitate positioning of an end-effector at any point within the 25-ft- or 50-ft-diameter USTs in the GAAT OU

    Various types of waste have been generated during the 50-year history of the Hanford Site. Regulatory changes in the last 20 years have provided the emphasis for better management of these wastes. Interpretations of the Atomic Energy Act of 1954 (AEA), the Resource Conservation and Recovery Act of 1976 (RCRA), and the Hazardous and Solid Waste Amendments (HSWA) have led to the definition of radioactive mixed wastes (RMW). The radioactive and hazardous properties of these wastes have resulted in the initiation of special projects for the management of these wastes. Other solid wastes at the Hanford Site include low-level wastes, transuranic (TRU), and nonradioactive hazardous wastes. This paper describes a system for the treatment, storage, and disposal (TSD) of solid radioactive waste

    Full Text Available In this article, I examine the content of socialism in the work of Cornelius Castoriadis in its potential relation to the current emergence of collaborative commons. I begin by analysing Castoriadis’ conceptualisation of socialism, as crystallised in the project of individual and collective autonomy, which was initially demonstrated in the journal Socialisme ou Barbarie (1949-1965 and evolved thereafter in his later writings. I continue by briefly presenting some basic points of criticism, after which I explore the potential compatibility of Castoriadis’ political project with the prospect of market socialism, as the latter emerges today in the form of collaborative commons. I argue, in particular, that collaborative commons echo Castoriadis’ conception of socialism in several respects. Finally, I critically develop a series of proposals made by Vasilis Kostakis and Michel Bauwens that could provide fertile ground for further discussion on the prospect of the commons.

A empresa estudada apresenta um padrão dos mais avançados na dimensão organizacional das relações de trabalho ou no local de trabalho considerado o contexto brasileiro. A solução de conflitos do trabalho nesta empresa aponta fortemente para um padrão negocial em relação ao estatutário (Zylberstajn e Pastore, 1985, o que levou alguns autores a indicar um modo de cooperação-conflitiva para lidar com as relações de trabalho (Rodrigues, 1997 e uma via institucionalizada de inserção dos trabalhadores nos processos de inovação tecnológica e gerencial (Bresciani, 2002. O esquema montado dentro da empresa foi resultado da estratégia do sindicato no local de trabalho e da gestão da empresa em particular da gestão de recursos humanos. A análise da experiência permitiu verificar além de um paradigma avançado de relações de trabalho, a afirmação de uma tendência ao corporativismo societário ou neo-corporativismo em relação ao corporativismo estatal típico do sistema trabalhista brasileiro.

    Municipal solid waste (MSW) is a source of biomass material that can be utilized for bioenergy production with minimal additional inputs. MSW resources include mixed commercial and residential garbage such as yard trimmings, paper and paperboard, plastics, rubber, leather, textiles, and food wastes. Waste resources such as landfill gas, mill residues, and waste grease are already being utilized for cost-effective renewable energy generation. MSW for bioenergy also represents an opportunity to divert greater volumes of residential and commercial waste from landfills.

    Practices which lead to safe disposal of radioactive wastes permit the return of the wastes to man only at levels below maximum permissible concentrations, and do not prevent the development of resources which in the absence of disposal could make a significant contribution to man's well-being. The design of safe disposal procedures for any selected marine location is at present limited by our knowledge of several parts of the system which is involved in the return of radioactivity from the disposal site to man. Because of our present lack of knowledge, disposal procedures now being considered in the United States contain an unknown amount of ''over-design'' and, although they are believed to be conservative, are not unduly restrictive at present levels of waste generation. A better understanding of (a) turbulent mixing processes in the oceans, (b) the physical and chemical states of waste-product elements when in equilibrium with sea-water, and (c) the interaction of waste-product elements with the marine biota, their biological half-life, and the extent of their concentration or rejection by marine organisms in all trophic levels, will provide the basis for a more efficient and safer utilization of the marine environment for the disposal of radioactive wastes.

    1992-01-01

    Currently, limited storage and treatment capacity exists for commercial mixed waste streams. No commercial mixed waste disposal is available, and it has been estimated that if and when commercial mixed waste disposal becomes available, the costs will be high. If high disposal fees are imposed, generators may be willing to apply extraordinary treatment or regulatory approaches to properly dispose of their mixed waste. This paper explores the feasibility of several waste management scenarios and management options. Existing data on commercially generated mixed waste streams are used to identify the realm of mixed waste known to be generated. Each waste stream is evaluated from both a regulatory and technical perspective in order to convert the waste into a strictly low-level radioactive or a hazardous waste. Alternative regulatory approaches evaluated in this paper include a delisting petition) no migration petition) and a treatability variance. For each waste stream, potentially available treatment options are identified that could lead to these variances. Waste minimization methodology and storage for decay are also considered. Economic feasibility of each option is discussed broadly. Another option for mixed waste management that is being explored is the feasibility of Department of Energy (DOE) accepting commercial mixed waste for treatment, storage, and disposal. A study has been completed that analyzes DOE treatment capacity in comparison with commercial mixed waste streams. (author)

    The state of Nevada opposed DOE's development of a nuclear waste repository at Yucca Mountain. As a result, disputes have arisen over how Nevada has spent financial assistance provided by DOE to pay the state's repository program costs. This report reviews Nevada's use of about $32 million in grant funds provided by DOE through June 1989 and found that Nevada improperly spent about $1 million. Nevada used as much as $683,000 for lobbying and litigation expenses that were unauthorized or were expressly prohibited by law, court decision, or grant terms; exceeded a legislative spending limit on socioeconomic studies by about $96,000; and used, contrary to grant terms, about $275,000 from one grant period to pay expenses incurred in the prior year. Also, Nevada did not always exercise adequate internal controls over grant funds, such as timely liquidation of funds advanced to contractors. A permissive approach to grant administration by DOE contributed to Nevada's inappropriate use of grant funds

Il apparaît pourtant que les transitions démocratiques qui se sont déroulées durant leurs mandats se sont soldées par un échec en dépit de leur sacrifice. La principale raison de cet échec fut leur réticence à institutionnaliser leur parti, le Parti du peuple pakistanais, qu’ils délaissèrent une fois arrivés au pouvoir, préférant fortifier leur pouvoir personnel en raison de leur obsession à l’égard de la bureaucratie civile et militaire.The members of the Bhutto family, especially Zulfikar Ali Bhutto and his daughter Benazir Bhutto, presented themselves as martyrs of democracy and claimed many times they were ready to sacrifice their life for the rise of democracy in Pakistan.

The main reason is their unfitness or reluctance to institutionalize their party, the Pakistan people’s Party, which they relinquished so as strenghten their personal rule due to their obsession with the civil and military bureaucracy.

    Context. When crossing the Hertzsprung gap, intermediate-mass stars develop a convective envelope. Fast rotators on the main sequence, or Ap star descendants, are expected to become magnetic active subgiants during this evolutionary phase. Aims: We compare the surface magnetic fields and activity indicators of two active, fast rotating red giants with similar masses and spectral class but different rotation rates - OU And (Prot = 24.2 d) and 31 Com (Prot = 6.8 d) - to address the question of the origin of their magnetism and high activity. Methods: Observations were carried out with the Narval spectropolarimeter in 2008 and 2013. We used the least-squares deconvolution (LSD) technique to extract Stokes V and I profiles with high signal-to-noise ratio to detect Zeeman signatures of the magnetic field of the stars. We then provide Zeeman-Doppler imaging (ZDI), activity indicators monitoring, and a precise estimation of stellar parameters. We use state-of-the-art stellar evolutionary models, including rotation, to infer the evolutionary status of our giants, as well as their initial rotation velocity on the main sequence, and we interpret our observational results in the light of the theoretical Rossby numbers. Results: The detected magnetic field of OU Andromedae (OU And) is a strong one. Its longitudinal component Bl reaches 40 G and presents an about sinusoidal variation with reversal of the polarity. The magnetic topology of OU And is dominated by large-scale elements and is mainly poloidal with an important dipole component, as well as a significant toroidal component. The detected magnetic field of 31 Comae (31 Com) is weaker, with a magnetic map showing a more complex field geometry, and poloidal and toroidal components of equal contributions. The evolutionary models show that the progenitors of OU And and 31 Com must have been rotating at velocities that correspond to 30 and 53%, respectively, of their critical rotation velocity on the zero age main sequence

    The outflow phenomenon is associated both with the early and the last phase of the stellar evolution. Recently, a unique bipolar outflow with an angular size of 1.2 degrees was discovered in the blister HII region Sh2-129. Ou4, nicknamed "The Giant Squid", is to our knowledge the bipolar outflow with the largest angular size ever found. We propose joint XMM-Newton/EPIC (35 ks) and Chandra/HRC-I (16 ks) observations to look for the driving source of Ou4 and to clarify the nature of this object.

    Radioactive waste generated from utilization of radioisotopes and each step of the nuclear fuel cycle and decommissioning of nuclear facilities are presented. On the safe management of radioactive waste management, international safety standards are established such as ''The Principles of Radioactive Waste Management (IAEA)'' and T he Joint Convention on the Safety of Radioactive Waste Management . Basic steps of radioactive waste management consist of treatment, conditioning and disposal. Disposal is the final step of radioactive waste management and its safety is confirmed by safety assessment in the licensing process. Safety assessment means evaluation of radiation dose rate caused by radioactive materials contained in disposed radioactive waste. The results of the safety assessment are compared with dose limits. The key issues of radioactive waste disposal are establishment of long term national strategies and regulations for safe management of radioactive waste, siting of repository, continuity of management activities and financial bases for long term, and security of human resources.

    residus radioactifs produits par les installations nucleaires. L'evaluation du risque encouru par les populations et la fixation des limites admissibles pour les rejets ne peuvent resulter que d'une connaissance exacte du cheminement des radioelements rejetes, depuis leur source d'emission jusqu'a l'homme. L'incorporation des radioelements dans les chaines alimentaires constitue le premier risque a prendre en consideration. Les facteurs de passage doivent etre envisages, dans toutes les etapes de cette transmission, qu'elles interessent les milieux physiques ou les milieux proprement biologiques, du fait de leur continuite et de leur interdependance. Enfin, les donnees de caractere socio-economique et dietetique doivent etre recueillies pour conduire a une evaluation des risques et des niveaux admissibles reposant non sur des donnees theoriques mais sur des bases concretes et experimentales. Le risque d'accidents nucleaires dans l'industrie atomique, bien que de probabilite tres reduite, doit etre pris en consideration du fait de la gravite de leurs consequences. Les problemes sanitaires se posent d'une part dans le domaine de l'hygiene professionnelle, d'autre part dans celui de l'hygiene publique. Le premier domaine implique un risque double: d'irradiation et de contamination. Le domaine public n'est soumis essentiellement qu'au risque de contamination par les substances radioactives liberees accidentellement dans le milieu. Les etudes sanitaires a mener dans ce domaine comprennent, de ce fait, les recherches sur la therapeutique des irradiations ou des contaminations mais aussi celles relatives au transfert des radioelements depuis l'installation accidentee jusqu'a l'homme, principalement a travers les chaines alimentaires, dans leurs composantes physiques comme dans leurs composantes biologiques. De telles etudes sont a la base des decisions d'ordre sanitaire qu'il conviendrait de prendre dans le cas d'un accident. (auteurs)

    Full Text Available Cet article analyse les limites du naturalisme social que Laurence Kaufman et Laurent Cordonier proposent d’adopter dans cette même revue, en critiquant leur plaidoyer pour l’intégration des savoirs des sciences cognitives et des sciences humaines et sociales. Cette critique repose sur la réfutation de trois idées soutenues par les auteurs : 1 la description scientifique des mécanismes cognitifs élémentaires fournit une explication causale des conduites sociales qui doit se substituer à celles des sciences humaines et sociales ; 2 le recours au naturalisme permet de falsifier les préconceptions que ces dernières continuent à entretenir ; 3 le programme de naturalisation de l’esprit n’implique aucune forme de réductionnisme. Cette triple critique permet de rejeter leur appel en faveur d’un modèle intégré de la conduite humaine, en avançant un constat : dans la mesure où on ne sait pas comment combler le hiatus qui sépare les descriptions détaillées du cerveau au travail de l’explication des conduites des individus et de la manière dont ils en assurent la coordination dans le temps même où ils agissent en commun, les sciences humaines et sociales ont peu de choses à aller glaner du côté des sciences cognitives pour améliorer la manière dont elles analysent l’action. C’est que le travail de celles-ci se situe soit au niveau infra-humain du fonctionnement moléculaire, soit au niveau supra-humain de l’évolution ; et que seules les sciences humaines et sociales placent leurs analyses à un niveau simplement humain, en faisant des individus tels qu’ils vivent ensemble la mesure de toutes les choses qui les concernent. Ce qu’elles ne peuvent faire sur un mode naturaliste.Cognitive sciences are not social sciencesThis article examines the limits of the social naturalism proposed by Laurence Kauffman and Laurent Cordonier in this journal by criticizing their plea concerning knowledge integration of cognitive sciences as well as humanities and social sciences. This critic relies upon the rebuttal of the three ideas backed by the authors: 1 the scientific description of cognitive elementary mechanisms gives a causal explanation of social conducts that must substitute itself to the ones of humanities and social sciences; 2 the use of naturalism allows a forgery of preconceived ideas the they continue to maintain; 3 the naturalization of the mind program doesn’t imply forms of reductionism. This triple critic allows a rejection of their appeal in favor of an integrated model of human conduct by putting forward a statement: since we do not know how to fill the gap that divides detailed descriptions of the working brain from the explanations of the individuals’ conducts and the ways in which they coordinate these personal conducts and the public ones, humanities and social sciences have little to gain from the cognitive sciences’ side in order to improve their analyses of action. It is because their work is located either at a subhuman level of molecular functioning or at a superhuman level of evolution; and only humanities and social sciences place their analyses simply at a human level by using humans as they live together as a measure of everything that concerns them. What they cannot do on a naturalist mode.Las ciencias cognitivas no son ciencias sobre la sociedad.Respuesta al artículo de Laurence Kaufman y Laurent Cordonier, « Vers un naturalisme social- Hacia un naturalismo social »En este artículo se analizan los límites del naturalismo social que Laurence Kaufman y Laurent Cordonier adoptan en esta revista, y se critican los argumentos para integrar los conocimientos de las ciencias cognitivas en las ciencias sociales. Esta crítica se basa en la refutación de tres ideas contenidas: 1 la descripción científica de los mecanismos cognitivos elementales suministra una explicación causal de los comportamientos sociales que debe reemplazar el de las ciencias sobre la sociedad; 2 La utilización del naturalismo falsifica las concepciones adquiridas que estas últimas producen; 3 el programa de naturalización de la capacidad de pensar no implica reduccionismo alguno. Esta triple crítica nos permite rechazar la propuesta en favor de un modelo integrado del comportamiento humano y para ello se pone en evidencia que en la medida en que no se sabe cómo suprimir el vacío que divide las descripciones detalladas del cerebro en funcionamiento de la explicación de los comportamientos de las personas y de la manera como se coordinan temporalmente aunque actúen al unísono, las ciencias de la sociedad no pueden perder el tiempo en el terreno de las ciencias cognitivas para mejorar la manera de analizar las cosas. Porque el ámbito de estas últimas se sitúa o bien a nivel de lo infrahumano del funcionamiento molecular, o bien a nivel supra humanó de la evolución y que solo las ciencias sociales sitúan sus análisis a un nivel puramente humano haciendo que los individuos, tal como viven juntos la medida de todas las cosas, cosas que no pueden hacerse a nivel del naturalismo.

    Recognition of the importance of the safe management of radioactive waste means that, over the years, many well-established and effective techniques have been developed, and the nuclear industry and governments have gained considerable experience in this field. Minimization of waste is a fundamental principle underpinning the design and operation of all nuclear operations, together with waste reuse and recycling. For the remaining radioactive waste that will be produced, it is essential that there is a well defined plan (called a waste treatment path) to ensure the safe management and ultimately the safe disposal of radioactive waste so as to guarantee the sustainable long term deployment of nuclear technologies

    Full Text Available CONTEXTO: A realização de diagnóstico neurológico e psiquiátrico em ambiente de emergência hospitalar com freqüência é uma tarefa complexa e exige colaboração interdisciplinar. Um dos diagnósticos diferenciais de doenças neurológicas é o transtorno conversivo, cuja característica principal é a presença de sintomas afetando funções motoras ou sensoriais, que sugerem desordem clínica ou neurológica, porém sem doença orgânica subjacente que explique o quadro. RELATO DE CASO: Os autores relatam o caso de uma paciente de 23 anos com apresentação clínica atípica de acidente vascular cerebral, afasia global sem hemiparesia, que foi inicialmente diagnosticada como transtorno psiquiátrico pelo serviço de clínica médica de emergência. CONCLUSÃO: Certas apresentações neurológicas podem ser interpretadas como transtorno conversivo pelas similaridades clínicas entre as duas desordens, raridade do quadro clínico, pela presença de sintomatologia psiquiátrica e fatores psicossociais nos pacientes neurológicos. Mesmo com apresentações neurológicas atípicas e sintomas psiquiátricos, pacientes com quadro sugestivo de transtorno conversivo devem ser sempre investigados de forma interdisciplinar.BACKGROUND: The neurologic and psychiatric diagnosis in emergency settings are difficult tasks and require interdisciplinary effort. Conversion disorder is one of the differential diagnosis for certain neurologic disorders. The main characteristic is motor or sensory deficits suggesting neurologic or medical condition, but without organic disease that explains the symptoms. CASE REPORT: We present a 23 year-old-woman with an atypical clinical presentation of stroke: global aphasia without hemiparesis. This patient was initially diagnosed with conversion disorder by the internal medicine service in the emergency room. CONCLUSION: Some rare neurologic diseases can be interpreted as conversive disorders due to some reasons

    Full Text Available Este ensaio chama a atenção para a grave doença que atingiu a Universidade nos nossos dias. O recurso à metáfora do 'sarcófago' e do 'Leito de Procrustes' visa: acentuar o facto de que a Universidade está a abandonar a sua missão tradicional e a sofrer transformações perigosas; expressar a esperança de que ela se liberte das forças que a constrangem e consiga ressuscitar numa forma nova. Com efeito, a Universidade está sendo capturada pela ideologia, pelo pensamento, pela terminologia e pelos interesses do neoliberalismo e do mercado. Consequentemente, ela perde autonomia e voz e deixa de ter identidade, linguagem e pensamento próprios. Em vez de ser uma instituição ao serviço da Humanidade, da sociedade, da cultura, da democracia e da liberdade, a Universidade torna-se um fator e instrumento de propagação das doutrinas e receitas dos potentados financeiros e 'mercadológicos'. Tudo isto é bem visível no 'reformismo' e nas orientações da sua reorganização e governação, na oferta e no perfil dos seus cursos. Tal como o mercado, a Universidade já não oferece nada; só vende. Assim, a Universidade é cúmplice e corresponsável pela crise civilizacional, cultural, ética, moral e social que grassa no mundo. Em conclusão, a Universidade está a tornar-se uma instituição humana e socialmente irrelevante, sem capacidade de irradiar influências exemplares e positivas. Para reverter a situação, os protagonistas da Universidade têm que a tirar do 'sarcófago' ou do 'Leito de Procrustes', no qual, por ação ou omissão, a deixaram aprisionar.

  6. Radioactive Waste in Perspective

    International Nuclear Information System (INIS)

    2011-01-01

    Large volumes of hazardous wastes are produced each year, however only a small proportion of them are radioactive. While disposal options for hazardous wastes are generally well established, some types of hazardous waste face issues similar to those for radioactive waste and also require long-term disposal arrangements. The objective of this NEA study is to put the management of radioactive waste into perspective, firstly by contrasting features of radioactive and hazardous wastes, together with their management policies and strategies, and secondly by examining the specific case of the wastes resulting from carbon capture and storage of fossil fuels. The study seeks to give policy makers and interested stakeholders a broad overview of the similarities and differences between radioactive and hazardous wastes and their management strategies. Contents: - Foreword; - Key Points for Policy Makers; - Executive Summary; - Introduction; - Theme 1 - Radioactive and Hazardous Wastes in Perspective; - Theme 2 - The Outlook for Wastes Arising from Coal and from Nuclear Power Generation; - Risk, Perceived Risk and Public Attitudes; - Concluding Discussion and Lessons Learnt; - Strategic Issues for Radioactive Waste; - Strategic Issues for Hazardous Waste; - Case Studies - The Management of Coal Ash, CO 2 and Mercury as Wastes; - Risk and Perceived Risk; - List of Participants; - List of Abbreviations.

    1995-01-01

    Remediation of the Department of Energy (DOE) Fernald site located north of Cincinnati will generate large quantities of low-level radwaste. This volume includes approximately 1,050,000 tons of material to be removed from eight waste pits comprising Operable Unit 1 (OU-1). The remedial alternative selected includes waste material excavation, drying and transportation by rail to a burial site in the arid west for disposal. Rail transportation was selected not only because rail transportation is safer than truck transportation, but also because of the sheer magnitude of the project and the availability of bulk rail car unloading facilities at a representative disposal site. Based upon current waste quantity estimates as presented in the Feasibility Study for OUI, a fully-loaded 47-car unit train would depart the Fernald site weekly for five years. This paper illustrates the steps taken to obtain agency and public acceptance of the Record of Decision for the remedy which hinged on rail transportation. A preliminary, but detailed, rail transportation plan was prepared for the project to support a series of CERCLA public meetings conducted in late 1994. Some of the major issues addressed in the plan included the following: (1) Scope of project leading to selection of rail transportation; (2) Waste classification; (3) Rail Company overview; (4) Train configuration and rail car selection; (5) Routing; (6) Safety; (7) Prior Notification Requirements (8) Emergency Response. A series of three public meetings identified a number of issues of prime concern to Fernald stakeholders. Following resolution of these issues during the public comment period, a Record of Decision (ROD) approving implementation of the rail transportation strategy was approved pending incorporation of EPA and State of Ohio comments on December 22, 1994

    ITER will produce solid radioactive waste during its operation (arising from the replacement of components and from process and housekeeping waste) and during decommissioning (de-activation phase and dismantling). The waste will be activated by neutrons of energies up to 14 MeV and potentially contaminated by activated corrosion products, activated dust and tritium. This paper describes the waste origin, the waste classification as a function of the French national agency for radioactive waste management (ANDRA), the optimization process put in place to reduce the waste radiotoxicity and volumes, the estimated waste amount based on the current design and maintenance procedure, and the overall strategy from component removal to final disposal anticipated at this stage of the project.

    The Hanford Waste Vitrification Plant (HWVP) is being designed to immobilize pretreated Hanford high-level waste and transuranic waste in borosilicate glass contained in stainless steel canisters. Testing is being conducted in the HWVP Technology Development Project to ensure that adapted technologies are applicable to the candidate Hanford wastes and to generate information for waste form qualification. Empirical modeling is being conducted to define a glass composition range consistent with process and waste form qualification requirements. Laboratory studies are conducted to determine process stream properties, characterize the redox chemistry of the melter feed as a basis for controlling melt foaming and evaluate zeolite sorption materials for process waste treatment. Pilot-scale tests have been performed with simulated melter feed to access filtration for solids removal from process wastes, evaluate vitrification process performance and assess offgas equipment performance. Process equipment construction materials are being selected based on literature review, corrosion testing, and performance in pilot-scale testing. 3 figs., 6 tabs

    Full Text Available Along with being a dynamic process that affects large areas, desertification is also one of the most serious problems in many countries. The effects of this phenomenon threaten the sustainability of natural resources, namely water resources, agricultural production and major basic infrastructure, specifically roads and habitations. Several factors exacerbate this phenomenon such as the climate dryness, the geological and morphological characteristics of the terrain, the irrational use of space, population growth and the over-exploitation of vegetation and water resources. This work aims to evaluate the desertification index in the Oued-El-Maleh watershed, through the integration of key factors involved in the MEDALUS model (Mediterranean Desertification and Land Use within a GIS. The model includes among its indexes: climate, vegetation, soil and management. Each index was obtained by the combination of sub-indexes. All the factors, measured and integrated into a geographic information system, enabled us to spatialize, on a synthetic map, the degree of the desertification effect throughout the watershed. This map is a managing tool available for decision-making regarding the selection of priority areas in the fight against desertification. High sensitivity to desertification class represents only 35% of the watershed. This class is concentrated in the north of the study area that corresponds to plains and low altitude. This could be explained by the dominance of agro-pastoral activity and the presence of a big population pressure.

    Waters from the Terminal complex (TC) in the Souf region have been gushing since Spring1956 through the first drilling carried out in the municipality of Guemmar (El-Oued) to ensure the need for drinking water requirements. Water needs of the habitat and farmers are increasing with the population growth in the Souf region; there are 153 boreholes in the Terminal complex for Habitat needs, of which more than 80% are available for drinking water supply. These needs are causing negative consequences for the serene life of the Souafa by the phenomenon of water upwellings, the free water table, and the change in the quality of the waters from the Terminal complex. Our work will be conducted to produce a piezometric map of the Souf Terminal complex and to conduct a study on the quality of water resources in the Algerian south-east, leading to a diagnosis of pollution and its impact on the water. The quality of water resources is examined by the establishment of sampling and water analysis campaigns for both irrigation and public consumption, following the static measurement of water levels in the network boreholes of TC Monitoring.

    The mission of the US Department of Energy's (DOE) Mixed Waste Focus Area (MWFA) is to provide acceptable technologies that enable implementation of mixed waste treatment systems which are developed in partnership with end-users, stakeholders, tribal governments, and regulators. To accomplish this mission, a technical baseline was established in 1996 and revised in 1997. The technical baseline forms the basis for determining which technology development activities will be supported by the MWFA. The primary attribute of the technical baseline is a set of prioritized technical deficiencies or roadblocks related to implementation of mixed waste treatment systems. The Waste Form Initiative (WFI) was established to address an identified technical deficiency related to waste form performance. The primary goal of the WFI was to ensure that the mixed low-level waste (MLLW) treatment technologies being developed, currently used, or planned for use by DOE would produce final waste forms that meet the waste acceptance criteria (WAC) of the existing and/or planned MLLW disposal facilities. The WFI was limited to an evaluation of the disposal requirements for the radioactive component of MLLW. Disposal requirements for the hazardous component are dictated by the Resource Conservation and Recovery Act (RCRA), and were not addressed. This paper summarizes the technical basis, strategy, and results of the activities performed as part of the WFI

    Radioactive wastes generated by nuclear activities must be reprocessed using specific treatments before packaging, storage and disposal. This digest paper gives first a classification of radioactive wastes according to their radionuclides content activity and half-life, and the amount of wastes from the different categories generated each year by the different industries. Then, the radiotoxicity of nuclear wastes is evaluated according to the reprocessing treatments used and to their environmental management (surface storage or burial). (J.S.)

  16. Solid waste combustion for alpha waste incineration

    International Nuclear Information System (INIS)

    Orloff, D.I.

    1981-02-01

    Radioactive waste incinerator development at the Savannah River Laboratory has been augmented by fundamental combustion studies at the University of South Carolina. The objective was to measure and model pyrolysis and combustion rates of typical Savannah River Plant waste materials as a function of incinerator operating conditions. The analytical models developed in this work have been incorporated into a waste burning transient code. The code predicts maximum air requirement and heat energy release as a function of waste type, package size, combustion chamber size, and temperature. Historically, relationships have been determined by direct experiments that did not allow an engineering basis for predicting combustion rates in untested incinerators. The computed combustion rates and burning times agree with measured values in the Savannah River Laboratory pilot (1 lb/hr) and full-scale (12 lb/hr) alpha incinerators for a wide variety of typical waste materials

  9. Radioactive wastes management

    International Nuclear Information System (INIS)

    Albert, Ph.

    1999-01-01

    This article presents the French way to deal with nuclear wastes. 4 categories of radioactive wastes have been defined: 1) very low-level wastes (TFA), 2) low or medium-wastes with short or medium half-life (A), 3) low or medium-level wastes with long half-life (B), and 4) high-level wastes with long half-life (C). ANDRA (national agency for the management of radioactive wastes) manages 2 sites of definitive surface storage (La-Manche and Aube centers) for TFA-wastes. The Aube center allows the storage of A-wastes whose half-life is less than 30 years. This site will receive waste packages for 50 years and will require a regular monitoring for 300 years after its decommissioning. No definitive solutions have been taken for B and C wastes, they are temporarily stored at La Hague processing plant. Concerning these wastes the French parliament will have to take a decision by 2006. At this date and within the framework of the Bataille law (1991), scientific studies concerning the definitive or retrievable storage, the processing techniques (like transmutation) will have been achieved and solutions will be proposed. These studies are numerous, long and complex, they involve fresh knowledge in geology, chemistry, physics,.. and they have implied the setting of underground facilities in order to test and validate solutions in situ. This article presents also the transmutation technique. (A.C.)

    1997-01-01

    There are two types of repositories for the low level radioactive wastes in Japan. One is a trench type repository only for concrete debris generated from the dismantling of the research reactor. According to the safety assurance system, Japan Atomic Energy Research Institute (JAERI) has disposed of the concrete debris arose from the dismantling of the Japan Power Demonstration Reactor (JPDR). The other type is the concreted pit with engineered barriers. Rokkasho Low Level Radioactive Waste Disposal Center has this type of repository mainly for the power plant wastes. Japan Nuclear Fuel Ltd. (JNFL) established by electric power companies is the operator of the LLW disposal project. JNFL began the storage operation in 1992 and buried approximately 60,000 drums there. Two hundred thousand drums of uniformly solidified, waste may be buried ultimately. 4 refs, 3 tabs

Méthodologie : Une analyse du chi carré effectuée sur des données combinées des services de protection de l'enfance issues de l'Étude canadienne sur l'incidence des signalements de cas de violence et de négligence envers les enfants (ECI-2003 et ECI-2008 a permis de comparer 284 mères adolescentes (18 ans et moins et 800 jeunes mères (19 à 21 ans et leurs familles à 5 752 familles avec une mère de 22 ans ou plus. Résultats : Vingt-six pour cent des jeunes mères avaient 18 ans ou moins. La plupart recevaient de l'aide sociale comme principale source de revenu (68 % des familles avec une mère adolescente et 57 % des familles avec une mère jeune adulte contre 36 % des familles avec une mère de 22 ans ou plus. Les mères adolescentes et les mères jeunes adultes étaient plus susceptibles d'avoir été placées dans leur enfance que les mères de 22 ans ou plus (31 % et 23 % contre 10 % et présentaient plus fréquemment des facteurs de risque tels que l'alcoolisme (25 % et 23 % contre 18 % ou un manque de soutien social (46 % et 41 % contre 37 %. Les pourvoyeurs secondaires de soins dans les familles avec de jeunes mères étaient aussi associés à un plus grand nombre de facteurs de risque. Les familles de mères adolescentes ou jeunes adultes couraient un risque plus élevé de décision de placement de l'enfant pendant l'enquête (29 % et 27 % contre 17 %. Les mères couraient toutes le même risque d'être victimes de violence familiale et de présenter des problèmes de santé mentale. Conclusion : Dans cet échantillon de familles à risque élevé, les risques étaient plus importants pour les familles avec de jeunes mères que pour les familles auxquelles on les avait comparées.

    Full Text Available Lorsque débute la Première guerre carliste en Espagne, c’est là-bas que paraît se jouer le sort de l’absolutisme européen, aux prises avec le libéralisme conquérant. Les acteurs de ce conflit ainsi que l’écho de certaines batailles sont relayés dans l’opinion publique européenne, essentiellement par la presse et les revues, mais aussi au travers de nombreux ouvrages de circonstance qui sont la plupart du temps des témoignages de militaires s’étant engagés dans ce conflit. Dans cet article, il s’agit d’analyser le discours des légitimistes européens qui ont participé à la première guerre carliste en tant qu’observateurs ou acteurs engagés dans un conflit dont les enjeux allaient bien au-delà d’une simple querelle dynastique. Dans cette guerre civile se joue pour eux une idée de l’Europe qu’ils craignent de voir disparaître. Ils sont conscients que l’issue de ces combats peut faire basculer le destin de la cause légitimiste en Europe. La possibilité de lutter pour des idéaux qu’ils ne pouvaient pas toujours revendiquer dans leurs pays d’origine pousse un certain nombre d’officiers de carrière à s’engager dans l’armée carliste mais aussi à publier un certain nombre d’ouvrages destinés à célébrer l’héroïsme qui préside dans leur propre camp. Ces défenseurs de la légitimité vont au devant d’une mémoire collective qui est celle des vaincus et qui leur contesterait donc le droit d’exister. S’ils sont conscients que le présent ne leur appartient plus, ils mettent tout leur espoir dans l’avenir et dans la marque qu’ils laisseront dans l’histoire qui, un jour peut-être, leur rendra justice.When the first Carlist war starts in Spain, the fate of European absolutism, which is facing the increasing strength of liberalism, seems to be at stake there.

    High-level radioactive waste is produced at Idaho Chemical Processing Plant (ICPP) during the recovery of spent highly enriched nuclear fuels. Liquid waste is stored safely in doubly contained tanks made of steel. The liquid waste is calcined to a solid and stored safely in a retrievable form in doubly contained underground bins. The calcine can be treated further or left untreated in anticipation of ultimate storage. Fluidized bed calcination has been applied to many kinds of high-level waste. The environmental impact of high-level waste management at the ICcP has been negligible and should continue to be negligible. 13 refs

    Full Text Available Cet article porte sur l’expérience artistique en classe de langue sous l’angle des réactions verbales. Nous proposons d’analyser les interactions orales recueillies lors d’une activité de commentaire de photographies mise en œuvre en classe de français enseigné comme langue étrangère auprès d’apprenants adultes en contexte pluriculturel. Notre perspective est focalisée sur l’une des formes de réception des œuvres, l’immersion fictionnelle. Grâce à une analogie perçue entre l’univers fictionnel et le monde réel, les apprenants construisent de l’empathie envers l’un des personnages de la photographie, ce qui les amène à participer pleinement à la fiction. Ce phénomène se manifeste par l’attribution de paroles aux personnages de l’image. C’est à travers la notion de polyphonie énonciative que nous étudions différents extraits recueillis devant la photographie Les mariés d’Arthur Tress. Lorsque les apprenants font précéder les énoncés des personnages d’un verbe introducteur, ils se comportent comme des metteurs en scène donnant des instructions à leurs comédiens. Lorsque leurs énoncés sont dépourvus de verbes de dire, ils incarnent véritablement les personnages à la manière d’acteurs. Fictional Immersion: Combining Art and Emotion in the Language Classroom Abstract: The article deals with the verbal reactions induced by an artistic experience in a language classroom. Our perspective is to analyze the oral interactions triggered by an activity asking adult learners to comment on photographs in lessons of French taught as a foreign language in a pluricultural context. This paper focuses on fictional immersion, which is one of the possible reactions to the pictures. As they perceive a form of analogy between the fictional universe and the real world, the students build empathy with one of the characters in the photograph, which encourages them to fully participate in the fiction

    Full Text Available L’insurrection de 1947, qui a dressé les rebelles malgaches contre les colonisateurs français et a donné lieu à une violente répression, a été tenue dans l’oubli et le déni aussi bien par la mémoire coloniale que par le discours malgache. L’historiographie continue d’en donner des interprétations divergentes. Ces fluctuations des mémoires révèlent que le passé colonial hante le présent postcolonial. La littérature malgache, d’ailleurs, ne fait que peu de place à la représentation de ces événements, ce qui, là encore, traduit la gêne qui les entoure. Pourtant, un écrivain, Jean-Luc Raharimanana, leur consacre plusieurs de ses œuvres, nouvelle, roman, essai, pièce de théâtre. Il est hanté par cette date à partir de laquelle il élabore une réflexion générale sur les « mémoires multidirectionnelles » de l’histoire postcoloniale. Or précisément, l’histoire a rattrapé son œuvre : la tournée de sa pièce a été suspendue dans l’Océan Indien en 2008, ce qui a éveillé le spectre d’une censure par l’état français. Les interprétations divergentes de cette affaire sont peut-être paradoxalement la meilleure justice qui puisse être rendue à la rumeur, « tabataba », nom que l’on donna aux événements de 47 et que l’on considère comme une modalité de résistance discursive malgache.The rising of 1947, when Malagasy rebels stood against French settlers, and the brutal repression which followed, have been neglected and denied in both colonial memory and Malagasy discourse. Historians still offer conflicting analyses of the insurrection. These fluctuating memories reveal to what extent the postcolonial present is still haunted by the colonial past. Significantly, the events of 1947 are rarely represented in Malagasy literature. Writer Jean-Luc Raharimanana is a rare exception. Indeed he has devoted quite a few of his works—a short story, a novel, an essay, and a play—to the

    Major tasks in this NRC-sponsored program include: (1) an evaluation of the acceptability of low-level solidified wastes with respect to minimizing radionuclide releases after burial; and (2) an assessment of the influence of pertinent environmental stresses on the performance of high-integrity radwaste container (HIC) materials. The waste form performance task involves studies on small-scale laboratory specimens to predict and extrapolate: (1) leachability for extended time periods; (2) leach behavior of full-size forms; (3) performance of waste forms under realistic leaching conditions; and (4) leachability of solidified reactor wastes. The results show that leach data derived from testing of small-scale specimens can be extrapolated to estimate leachability of a full-scale specimen and that radionuclide release data derived from testing of simulants can be employed to predict the release behavior of reactor wastes. Leaching under partially saturated conditions exhibits lower releases of radionuclides than those observed under the conventional IAEA-type or ANS 16.1 leach tests. The HIC assessment task includes the characterization of mechanical properties of Marlex CL-100, a candidate radwaste high density polyethylene material. Tensile strength and creep rupture tests have been carried out to determine the influence of specific waste constituents as well as gamma irradiation on material performance. Emphasis in ongoing tests is being placed on studying creep rupture while the specimens are in contact with a variety of chemicals including radiolytic by-products of irradiated resin wastes. 12 references 6 figures, 2 tables

    Ono, Akira; Matsushita, Mitsuhiro; Doi, Makoto; Nakatani, Seiichi.

    1990-01-01

    In a waste container, water-proof membranes and rare earth element layers are formed on the inner surface of a steel plate concrete container in which steel plates are embedded. Further, rear earth element detectors are disposed each from the inner side of the steel plate concrete container by way of a pressure pipe to the outer side of the container. As a method for actually containing wastes, when a plurality of vessels in which wastes are fixed are collectively enhoused to the waste container, cussioning materials are attached to the inner surface of the container and wastes fixing containers are stacked successively in a plurality of rows in a bag made of elastic materials. Subsequently, fixing materials are filled and tightly sealed in the waste container. When the waste container thus constituted is buried underground, even if it should be deformed to cause intrusion of rain water to the inside of the container, the rare earth elements in the container dissolved in the rain water can be detected by the detectors, the containers are exchanged before the rain water intruding to the inner side is leached to the surrounding ground, to previously prevent the leakage of radioactive nuclides.

    The purpose of this document is to study the solid waste issues brought about by a Type C Investigation; ''Disposal of Inappropriate Material in the Los Alamos County Landfill'' (May 28, 1993). The study was completed in August 1995 by Coleman Research Corporation, under subcontract number 405810005-Y for Los Alamos National Laboratory (LANL). The study confirmed the issues identified in the Type C investigation, and also ascertained further issues or problems. During the course of this study two incidents involving hazardous waste resulted in the inappropriate disposal of the waste. An accidental spill, on June 8, 1995, at one of Laboratory buildings was not handled correctly, and ended up in the LAC Landfill. Hazardous waste was disposed of in a solid waste container and sent to the Los Alamos County Landfill. An attempt to locate the hazardous waste at the LAC Landfill was not successful. The second incident involving hazardous waste was discovered by the FSS-8, during a random dumpster surveillance. An interim dumpster program managed by FSS-8 discovered hazardous waste and copper chips in the solid waste, on August 9, 1995. The hazardous waste and copper chips would have been transported to the LAC Landfill if the audit team had not brought the problem to the awareness of the facility waste management personnel

During the course of this study two incidents involving hazardous waste resulted in the inappropriate disposal of the waste. An accidental spill, on June 8, 1995, at one of Laboratory buildings was not handled correctly, and ended up in the LAC Landfill. Hazardous waste was disposed of in a solid waste container and sent to the Los Alamos County Landfill. An attempt to locate the hazardous waste at the LAC Landfill was not successful. The second incident involving hazardous waste was discovered by the FSS-8, during a random dumpster surveillance. An interim dumpster program managed by FSS-8 discovered hazardous waste and copper chips in the solid waste, on August 9, 1995. The hazardous waste and copper chips would have been transported to the LAC Landfill if the audit team had not brought the problem to the awareness of the facility waste management personnel.

    Full Text Available RESUMO O objetivo deste trabalho foi descrever os achados eletrocardiográficos de 11 onças- pardas (Puma concolor. Os animais foram sedados com 0,15mg/kg de detomidina associado a 5mg/kg de cetamina e mantidos anestesiados com sevoflurano (GSEVO, n=6 ou isoflurano (GISO, n=5. A frequência cardíaca foi de 95 ± 13bpm. As alterações observadas nos animais no GSEVO foram: atrial standtill com condução ventricular, episódios isolados de contração ventricular prematura, bloqueio atrioventricular de primeiro grau, diminuição da amplitude do complexo QRS, onda S profunda e aumento da amplitude da onda T. No grupo GISO, observou-se bloqueio de ramo direito do feixe de His, bloqueio atrioventricular de primeiro grau e aumento da amplitude da onda T. Arritmias não puderam ser associadas ao uso dos anestésicos inalatórios devido à não sensibilização do miocárdio às catecolaminas. Achados como o BAV de primeiro grau pode ter ocorrido devido ao uso de agonistas α-2 adrenérgicos. Este estudo aumentou o conhecimento sobre as alterações eletrocardiográficas em onças-pardas anestesiadas, entretanto mais estudos são necessários para correlacionar estes achados ao uso de agentes anestésicos.

    Full Text Available Tomando como referência epistemológica efeitos provocados pela violência contemporânea, discursiva e midiatizada, o artigo problematiza lugares possíveis a serem ocupados pelas teorias da comunicação diante da violência como fato social demarcado por incessantes processos de simbolização. Propõe, neste sentido, a possibilidade de uma narrativa sobre a violência que toma por inspiração o princípio lyotardiano da anamnese, defendendo, igualmente, sua localização em uma linhagem teórica ancorada no pensamento crítico. Propõe, finalmente, identificar dinâmicas de consumo cultural que, no Brasil, sinalizam reapropriações de cenas de violência, seja para afirmá-la, seja para contestá-la ou contrapô-la. Palavras-chave: Violência; comunicação; consumo. Abstract Taking as an epistemological reference the effects of contemporary violence, both discursive and mediated, the article focuses on communication theories, considering among other facts the symbolic forms with which social violence is constructed. It postulates, in this direction, the possibilityof a narrative that takes for inspiration lyotard’s principle of anamnese, defending, equally, its localization in the theoretical framework of critical theory. Finally, intends to identify some dynamics of cultural consumption that, in Brazil, signal re-appropriations of violence scenes, either to affirm or contest it. Keywords: Violence; communication; consumption.

    Full Text Available A motivação é fundamental para o envolvimento dos estudantes na escola. Para a teoria da autodeterminação, o estilo motivacional do professor, que pode controlar ou promover a autonomia, contribui para fomentar a ocorrência de tipos qualitativamente diferenciados de motivação. Neste estudo, de natureza exploratória, foram analisadas as interações entre dois professores e seus alunos. A amostra foi composta de acordo com o desempenho de 39 professores na avaliação do estilo motivacional, mediante a aplicação de um instrumento de autorrelato, problemas na escola. Desse total, dois professores, um com estilo motivacional promotor de autonomia e outro com uma orientação para o controle, tiveram suas aulas observadas em sete sessões, com o objetivo de levantar dados para a elaboração de um protocolo que continha categorias de interações. Foram então realizadas outras sete sessões de observação. Os resultados indicaram que, apesar de terem sido encontradas diferenças entre os desempenhos na avaliação do estilo motivacional, os professores interagiram com seus alunos de modo preferencialmente controlador. No entanto, o professor que promovia a autonomia interagiu de modo menos controlador no gerenciamento do tempo destinado para a realização das atividades em classe quando comparado ao professor controlador, além de oferecer feedback informativo. As implicações educacionais dos resultados são analisadas.

    Full Text Available A mitilicultura no Brasil se baseia no mexilhão Perna perna (Linnaeus, 1758, que é encontrado em todo o litoral brasileiro, sendo especialmente abundante do Espírito Santo a Santa Catarina. Nos últimos anos, foi lançada a hipótese de que P. perna seja uma espécie exótica no litoral brasileiro. A hipótese se baseia na análise da malacofauna presente em sítios arqueológicos. Todas as contestações levantadas não remetem à uma conclusão, pois precisam de estudos específicos, com metodologias claras, aliando arqueologia, ecologia e biologia molecular. O objetivo deste trabalho foi estudar a condição de nativo ou exótico do mexilhão Perna perna no Brasil, a partir de levantamento dos resultados em sítios arqueológicos, de técnicas moleculares e de datação de conchas com C14. A datação indicou que as amostras de Perna perna do sítio arqueológico Rio do Meio/Jurerê, Florianópolis/SC, têm idade de 720±30 e 780±30 anos. O cálculo do tempo de divergência indicou que a separação das populações brasileiras e africanas ocorreu por volta de 200 mil anos. Os resultados apontam a presença da espécie no território brasileiro muito antes do descobrimento do Brasil pelos portugueses no ano de 1500, indicando que P. perna é de fato uma espécie nativa.

    2015-12-01

    Full Text Available A metáfora da “encruzilhada” foi usada por Fernando de Azevedo, nos anos de 1920, para obscurecer os diferentes interesses de classes sob o litígio “tradicionais e renovadores” e definir o sentido burguês da escola pública. A encruzilhada de classe, então elidida por Azevedo, permanece e a essencial relação Capital-Trabalho tem sido dissolvida na designação “rico e pobre”. O debate proposto refere-se à encruzilhada do trabalho docente: produção de resultados ou formação humana. Baseadas em análises de documentos educacionais de Organizações Multilaterais, do Aparelho de Estado e numa literatura nacional e internacional, problematizamos as políticas destinadas aos professores, como as de recrutamento, avaliação, formação e gestão. Objetivamos colaborar para o esforço de compreender o horizonte do trabalho docente: compromisso com a educação da classe trabalhadora, promoção da contrainteriorização do projeto burguês, desalienação, formação da consciência crítica nos cursos de formação docente e nas lutas sociais, construção de um projeto histórico a contrapelo das demandas capitalistas. Concluímos que os professores são combatidos porque podem ensinar crianças, jovens e adultos a pensar historicamente de modo que questionem as relações sociais capitalistas e possam se ver como arquitetos do futuro, tendo como norte outra ordem social.

    Full Text Available Este artigo tem como objetivo abordar a problemática da exclusão digital sob o enfoque do analfabetismo funcional, salientando a importância da inclusão social efetiva como elemento importante na definição dessas terminologias. Também é objetivo do artigo observar esses conceitos quando relacionados com a aceleração das necessidades sociais e econômicas trazidas pela sociedade conectada em rede, notadamente após o advento da Web 2.0. Busca-se questionar – sem responder - se o cenário atual é de desafio desanimador ou de oportunidade para a inclusão digital. Para isso, são analisadas as conceituações trabalhadas antecipadamente, de “analfabetismo funcional” e de “exclusão digital”, em comparação com as novas necessidades e oportunidades sociais surgidas a partir da conexão instantânea oferecida pelas redes sociais e plataformas de colaboração. Para fins de ilustração otimista, são apresentados alguns exemplos de iniciativas de inclusão digital em redes sociais inclusivas, as quais obtiveram resultados satisfatórios. Ao fim, tece-se alguns comentários sobre políticas governamentais aplicadas atualmente, apenas para reflexão quanto a sua utilidade no atual cenário tecnológico.

A evidência encontrada leva a sugerir que, não obstante as empresas do setor são proclives a adotar o paradigma do marketing relacional, ainda coexistem com enfoques de conceitos de marketing transacional, isto pela incipiente aplicação do conceito e a técnica do Valor do Ciclo de Vida do Cliente (CLV em países da América Latina como parte do processo de gestão de clientes. A falta de aplicação do mesmo em setores dinâmicos como o consumo massivo constitui, em consequência, um tópico de interesse para a ciência administrativa e particularmente, para a disciplina do marketing; daí a intenção do artículo de chamar a atenção sobre este fato.

    Remediation efforts at the U.S. Department of Energy's Hanford Site require that many technical and scientific principles be combined for effectively managing and disposing the variety of wastes currently stored in underground tanks. Based on these principles, pretreatment technologies are being studied and developed to separate waste components and enable the most suitable treatment methods to be selected for final disposal of these wastes. The Tank Waste Treatment Science Task at Pacific Northwest Laboratory is addressing pretreatment technology development by investigating several aspects related to understanding and processing the tank contents. The experimental work includes evaluating the chemical and physical properties of the alkaline wastes, modeling sludge dissolution, and evaluating and designing ion exchange materials. This paper gives some examples of results of this work and shows how these results fit into the overall Hanford waste remediation activities. This work is part of series of projects being conducted for the Tank Waste Remediation System

    According to the Section 24 of the Finnish Radiation Decree (1512/91), the Finnish Centre for Radiation and Nuclear Safety shall specify the concentration and activity limits and principles for the determination whether a waste can be defined as a radioactive waste or not. The radiation safety requirements and limits for the disposal of radioactive waste are given in the guide. They must be observed when discharging radioactive waste into the atmosphere or sewer system, or when delivering solid low-activity waste to a landfill site without a separate waste disposal plan. The guide does not apply to the radioactive waste resulting from the utilization of nuclear energy of natural resources. (4 refs., 1 tab.)

    In this paper the authors explore the time dimension in nuclear waste disposal, with the hope of untangling future land use issues for a full range of radioactive waste facilities. The longevity and hazards presented by nuclear reactor irradiated (spent) fuel and liquid reprocessing waste are well known. Final repositories for these highly radioactive wastes, to be opened early in the 21st Century, are to be located deep underground in rural locations throughout the developed world. Safety concerns are addressed by engineered and geological barriers containing the waste containers, as well as through geographic isolation from heavily populated areas. Yet nuclear power plants (as well as other applications of atomic energy) produce an abundance of other types of radioactive wastes. These materials are generally known as low level wastes (LLW) in the United States, though their level of longevity and radioactivity can vary dramatically

    Final disposal of low level wastes has been carried out for 15 years on the shallow land disposal of the Manche in the north west of France. Final participant in the nuclear energy cycle, ANDRA has set up a new waste management system from the production center (organization of the waste collection) to the disposal site including the setting up of a transport network, the development of assessment, additional conditioning, interim storage, the management of the disposal center, records of the location and characteristics of the disposed wastes, site selection surveys for future disposals and a public information Department. 80 000 waste packages representing a volume of 20 000 m 3 are thus managed and disposed of each year on the shallow land disposal. The disposal of low level wastes is carried out according to their category and activity level: - in tumuli for very low level wastes, - in monoliths, a concrete structure, of the packaging does not provide enough protection against radioactivity [fr

    As human space activities have created more wastes on low and high Earth orbits over the past 50 years than the solar system injected meteorites over billions of years, this report gives an overview of this problem. It identifies the origins of these space debris and wastes (launchers, combustion residues, exploitation wastes, out-of-use satellites, accidental explosions, accidental collisions, voluntary destructions, space erosion), and proposes a stock list of space wastes. Then, it distinguishes the situation for the different orbits: low Earth orbit or LEO (traffic, presence of the International Space Station), medium Earth orbits or MEO (traffic, operating satellites, wastes), geostationary Earth orbit or GEO (traffic, operating satellites, wastes). It also discusses wastes and bacteria present on the moon (due to Apollo missions or to crash tests). It evokes how space and nuclear industry is concerned, and discusses the re-entry issue (radioactive boomerang, metallic boomerang). It also indicates elements of international law

    2008-01-01

    Plasma waste treatment has over the past decade become a more prominent technology because of the increasing problems with waste disposal and because of the realization of opportunities to generate valuable co-products. Plasma vitrification of hazardous slags has been a commercial technology for several years, and volume reduction of hazardous wastes using plasma processes is increasingly being used. Plasma gasification of wastes with low negative values has attracted interest as a source of energy and spawned process developments for treatment of even municipal solid wastes. Numerous technologies and approaches exist for plasma treatment of wastes. This review summarizes the approaches that have been developed, presents some of the basic physical principles, provides details of some specific processes and considers the advantages and disadvantages of thermal plasmas in waste treatment applications.

    One of the more frequent questions that arise when discussing nuclear energy's potential contribution to mitigating climate change concerns that of how to manage radioactive waste. Radioactive waste is produced through nuclear power generation, but also - although to a significantly lesser extent - in a variety of other sectors including medicine, agriculture, research, industry and education. The amount, type and physical form of radioactive waste varies considerably. Some forms of radioactive waste, for example, need only be stored for a relatively short period while their radioactivity naturally decays to safe levels. Others remain radioactive for hundreds or even hundreds of thousands of years. Public concerns surrounding radioactive waste are largely related to long-lived high-level radioactive waste. Countries around the world with existing nuclear programmes are developing longer-term plans for final disposal of such waste, with an international consensus developing that the geological disposal of high-level waste (HLW) is the most technically feasible and safe solution. This article provides a brief overview of the different forms of radioactive waste, examines storage and disposal solutions, and briefly explores fuel recycling and stakeholder involvement in radioactive waste management decision making

    The prospects of nuclear power development in the USA up to 2000 and the problems of the fuel cycle high-level radioactive waste processing and storage are considered. The problems of liquid and solidified radioactive waste transportation and their disposal in salt deposits and other geologic formations are discussed. It is pointed out that the main part of the high-level radioactive wastes are produced at spent fuel reprocessing plants in the form of complex aqueous mixtures. These mixtures contain the decay products of about 35 isotopes which are the nuclear fuel fission products, about 18 actinides and their daughter products as well as corrosion products of fuel cans and structural materials and chemical reagents added in the process of fuel reprocessing. The high-level radioactive waste management includes the liquid waste cooling which is necessary for the short and middle living isotope decay, separation of some most dangerous components from the waste mixture, waste solidification, their storage and disposal. The conclusion is drawn that the seccessful solution of the high-level radioactive waste management problem will permit to solve the problem of the fuel cycle radioactive waste management as a whole. The salt deposits, shales and clays are the most suitable for radioactive waste disposal [ru

    In the NUCEF, the researches on criticality safety have been performed at two critical experiment facilities, STACY and TRACY in addition to the researches on fuel cycle such as advanced reprocessing and partitioning in alpha-gamma concrete cells and glove boxes. Many kinds of radioactive wastes have been generated through the research activities. Furthermore, the waste treatment itself may produce some secondary wastes. In addition, the separation and purification of plutonium of several tens-kg from MOX powder are scheduled in order to supply plutonium nitrate solution fuel for critical experiments at STACY. A large amount of wastes containing plutonium and americium will be generated from the plutonium fuel treatment. From the viewpoint of safety, the proper waste management is one of important works in NUCEF. Many efforts, therefore, have been made for the development of advanced waste treatment techniques to improve the waste management in NUCEF. Especially the reduction of alpha-contaminated wastes is a major interest. For example, the separation of americium is planned from the liquid waste evolved alter plutonium purification by application of tannin gel as an adsorbent of actinide elements.

    The DOE has developed a National Mixed Waste Strategic Plan which calls for the construction of 2 to 9 mixed waste treatment centers in the Complex in the near future. LLNL is working to establish an integrated mixed waste technology development and demonstration system facility, the Mixed Waste Management Facility (MWMF), to support the DOE National Mixed Waste Strategic Plan. The MWMF will develop, demonstrate, test, and evaluate incinerator-alternatives which will comply with regulations governing the treatment and disposal of organic mixed wastes. LLNL will provide the DOE with engineering data for design and operation of new technologies which can be implemented in their mixed waste treatment centers. MWMF will operate under real production plant conditions and process samples of real LLNL mixed waste. In addition to the destruction of organic mixed wastes, the development and demonstration will include waste feed preparation, material transport systems, aqueous treatment, off-gas treatment, and final forms, thus making it an integrated ''cradle to grave'' demonstration. Technologies from offsite as well as LLNL's will be tested and evaluated when they are ready for a pilot scale demonstration, according to the needs of the DOE

    Japan's cataclysmic 2011 tsunami has become a vast, unwanted experiment in waste management. The seismic event and resulting Fukushima Daiichi radiation crisis created an awkwardly fortuitous rupture in Japanese nuclear practice that exposed the lax and problematic management of nuclear waste in this country to broader scrutiny, as well as distortions in its very conception. This article looks at the full spectrum of nuclear waste in post-tsunami Japan, from spent fuel rods to contorted reactor containment, and the ways that nuclear waste mirrors or diverges from more quotidian waste practices in Japanese culture. Significantly, the Fukushima Daiichi plant itself and its erstwhile banal surroundings have themselves transmuted into an unwieldy form of nuclear waste. The immense challenges of the Fukushima Daiichi site have stimulated a series of on-the-fly innovations that furnish perspective on more everyday nuclear waste practices in the industry. While some HLW can be reprocessed for limited use in today's reactors, it cannot be ignored that much of Japan's nuclear waste is simply converted into other forms of waste. In a society that has long been fixated on segregating filth, maintaining (imagined) purity, and managing proximity to pollution, the specter of nuclear waste looms over contemporary Japan and its ongoing debates over resources, risk, and Japanese nuclear identity itself

  19. Ferrocyanide tank waste stability

    Fowler, K.D.

    1993-01-01

    Ferrocyanide wastes were generated at the Hanford Site during the mid to late 1950s as a result of efforts to create more tank space for the storage of high-level nuclear waste. The ferrocyanide process was developed to remove 137 CS from existing waste and newly generated waste that resulted from the recovery of valuable uranium in Hanford Site waste tanks. During the course of research associated with the ferrocyanide process, it was recognized that ferrocyanide materials, when mixed with sodium nitrate and/or sodium nitrite, were capable of violent exothermic reaction. This chemical reactivity became an issue in the 1980s, when safety issues associated with the storage of ferrocyanide wastes in Hanford Site tanks became prominent. These safety issues heightened in the late 1980s and led to the current scrutiny of the safety issues associated with these wastes, as well as current research and waste management programs. Testing to provide information on the nature of possible tank reactions is ongoing. This document supplements the information presented in Summary of Single-Shell Tank Waste Stability, WHC-EP-0347, March 1991 (Borsheim and Kirch 1991), which evaluated several issues. This supplement only considers information particular to ferrocyanide wastes

    1995-01-01

    Waste Inspection Tomography (WIT) provides mobile semi-trailer mounted nondestructive examination (NDE) and assay (NDA) for nuclear waste drum characterization. WIT uses various computed tomography (CT) methods for both NDE and NDA of nuclear waste drums. Low level waste (LLW), transuranic (TRU), and mixed radioactive waste can be inspected and characterized without opening the drums. With externally transmitted x-ray NDE techniques, WIT has the ability to identify high density waste materials like heavy metals, define drum contents in two- and three-dimensional space, quantify free liquid volumes through density and x-ray attenuation coefficient discrimination, and measure drum wall thickness. With waste emitting gamma-ray NDA techniques, WIT can locate gamma emitting radioactive sources in two- and three-dimensional space, identify gamma emitting isotopic species, identify the external activity levels of emitting gamma-ray sources, correct for waste matrix attenuation, provide internal activity approximations, and provide the data needed for waste classification as LLW or TRU. The mobile feature of WIT allows inspection technologies to be brought to the nuclear waste drum storage site without the need to relocate drums for safe, rapid, and cost-effective characterization of regulated nuclear waste. The combination of these WIT characterization modalities provides the inspector with an unprecedented ability to non-invasively characterize the regulated contents of waste drums as large as 110 gallons, weighing up to 1,600 pounds. Any objects that fit within these size and weight restrictions can also be inspected on WIT, such as smaller waste bags and drums that are five and thirty-five gallons

  1. Stabilization of compactible waste

    1990-09-01

    This report summarizes the results of series of experiments performed to determine the feasibility of stabilizing compacted or compactible waste with polymers. The need for this work arose from problems encountered at disposal sites attributed to the instability of this waste in disposal. These studies are part of an experimental program conducted at Brookhaven National Laboratory (BNL) investigating methods for the improved solidification/stabilization of DOE low-level wastes. The approach taken in this study was to perform a series of survey type experiments using various polymerization systems to find the most economical and practical method for further in-depth studies. Compactible dry bulk waste was stabilized with two different monomer systems: styrene-trimethylolpropane trimethacrylate (TMPTMA) and polyester-styrene, in laboratory-scale experiments. Stabilization was accomplished by wetting or soaking compactible waste (before or after compaction) with monomers, which were subsequently polymerized. Three stabilization methods are described. One involves the in-situ treatment of compacted waste with monomers in which a vacuum technique is used to introduce the binder into the waste. The second method involves the alternate placement and compaction of waste and binder into a disposal container. In the third method, the waste is treated before compaction by wetting the waste with the binder using a spraying technique. A series of samples stabilized at various binder-to-waste ratios were evaluated through water immersion and compression testing. Full-scale studies were conducted by stabilizing two 55-gallon drums of real compacted waste. The results of this preliminary study indicate that the integrity of compacted waste forms can be readily improved to ensure their long-term durability in disposal environments. 9 refs., 10 figs., 2 tabs

  2. TSA waste stream and final waste form composition

    1993-01-01

    A final vitrified waste form composition, based upon the chemical compositions of the input waste streams, is recommended for the transuranic-contaminated waste stored at the Transuranic Storage Area of the Radioactive Waste Management Complex at the Idaho National Engineering Laboratory. The quantities of waste are large with a considerable uncertainty in the distribution of various waste materials. It is therefore impractical to mix the input waste streams into an ''average'' transuranic-contaminated waste. As a result, waste stream input to a melter could vary widely in composition, with the potential of affecting the composition and properties of the final waste form. This work examines the extent of the variation in the input waste streams, as well as the final waste form under conditions of adding different amounts of soil. Five prominent Rocky Flats Plant 740 waste streams are considered, as well as nonspecial metals and the ''average'' transuranic-contaminated waste streams. The metals waste stream is the most extreme variation and results indicate that if an average of approximately 60 wt% of the mixture is soil, the final waste form will be predominantly silica, alumina, alkaline earth oxides, and iron oxide. This composition will have consistent properties in the final waste form, including high leach resistance, irrespective of the variation in waste stream. For other waste streams, much less or no soil could be required to yield a leach resistant waste form but with varying properties

    2018-01-01

    Despite the title page is dated 1795, the fourth volume of Olivier's Entomologie, ou histoire naturelle des insectes was issued in two parts, one probably in 1795 and the second in 1800. All new taxa made available in this work have previously been dated 1795 in the literature. A list of new species described in 1795 and a list of those that have to be dated 1800 are appended. The genus Necrobia should be credited to Latreille, 1797, not Olivier, 1795.

    Full Text Available Atualmente, as potenciais interações entre fármacos e plantas medicinais e/ou medicamentos fitoterápicos são objetos de inúmeros estudos. Tais estudos são motivados pelo fato de que a fitoterapia é amplamente utilizada em associação com diversos fármacos. Nesta revisão, as informações sobre as principais interações entre produtos elaborados com valeriana ou alho foram localizadas, avaliadas e sistematizadas. Verificou-se que tais plantas podem alterar os perfis farmacocinéticos e/ou farmacodinâmicos de diversos fármacos, podendo provocar conseqüências graves aos pacientes. A valeriana pode aumentar os efeitos adversos dos benzodiazepínicos, reduzir a biodisponibilidade dos fármacos metabolizados pelo sistema P450-CYP3A4 e provocar hemorragias graves quando utilizada juntamente com anticoagulantes orais e antiplaquetários. O alho pode aumentar a biodisponibilidade dos relaxantes musculares, potencializar os efeitos terapêuticos e adversos dos hipoglicemiantes, provocar hemorragias quando administrado juntamente com anticoagulantes orais e antiplaquetários e reduzir a biodisponibilidade dos anti-retrovirais inibidores de protease. Porém, tais potenciais interações não são consensos na literatura, visto que há limitações metodológicas e diferenças significativas entre os estudos localizados. Mesmo assim, o uso de produtos à base de valeriana ou alho, associado com determinados fármacos, deve ser adequadamente monitorado por um profissional da área da saúde.

    Full Text Available Este trabalho apresenta a Ortodontia como atividade de meio, abordando as obrigações profissionais e as formas de se evitar e de se defender de ações judiciais. A grande parte dos litígios entre pacientes e ortodontistas se dá pelo fato equivocado, que ainda perdura, de que muitos juristas consideram a Ortodontia uma especialidade de fim, quando, na verdade, sua prática está sujeita a fatores que a caracterizam como atividade de meio. A Ortodontia deve ser, portanto, considerada uma obrigação de meio, onde o profissional tem o dever de utilizar todos os meios possíveis para atingir as expectativas do paciente, sem, entretanto, ter a obrigação de atingir o resultado idealizado. O ortodontista deve ser responsabilizado somente quando incorrer em imprudência, negligência, imperícia ou em caso de propaganda enganosa. Para evitar litígios, o ortodontista deve ter uma boa conduta profissional, registrando e mantendo arquivadas todas as etapas do tratamento, efetuando diagnósticos diferenciados, baseados nas características individuais, e escolhendo e conduzindo adequadamente o plano de tratamento.This study presents Orthodontics as a support activity, approaching professional obligations and ways to avoid and defend against legal action. A considerable part of litigation between patients and orthodontists results from the mistaken fact, which still persists, that many scholars regard Orthodontics as a core activity. In reality, its practice is subjected to factors that characterize it as a support activity. Orthodontics must be, therefore, regarded as a support obligation, whereupon the professional has the obligation to make use of all means possible to meet the patient's expectations - without, however, having the obligation to achieve the idealized result. The orthodontist must be made responsible only upon acts of imprudence, negligence, malpractice, or in the case of false advertising. In order to avoid litigation

Para tanto, segue em busca dos caminhos que a levam aos encontros, a partir do conceito de ritornelo deleuziano, desvelando o delineamento de um olhar, atravessado por memórias da infância, trechos poéticos e recortes de conceitos, a partir dos quais reconhece a relevância da mulher cômica e do território amazônida onde a autora está situada, enquanto constituíntes de um mapa, construído em jogo, ora correspondente à própria pesquisa, ora ao processo criativo em que deve resultar. Entre potências pessoais de seu feminino amazônida, a autora revela o processo de entranhar-se no objeto de pesquisa e criação, assumindo-o em jogo para sua cartografia. ABSTRACT This article runs through some clues to compose a playful cartography, wrought by the dip in the author’s sincerity, on her experience as Amazonian clown woman, willing to set up mee¬tings and transcriate them in a creative process, which is research also. Therefore, the author follows in search of paths that lead to encounters, throw the deleuzian concept of refrain, un¬veiling the design of a look, crossed by childhood memories, poetic excerpts and concepts clippings, from which she recognizes the importance of the clown woman and the Amazonian territory, where her performance is located, as constituents of a map, built in game, sometimes corresponding to the research itself, sometimes to the creative process that it might result. Among her personal Amazonian female potency, the author reveals the process of becoming ingrained on the object of research and creation, assuming it on a game, for her cartography.

Para comparação, estudamos o ciclo evolutivo destes insetos numa colônia há muito mantida em insetário. Nossos resultados mostram um desenvolvimento mais rápido da colônia recém- estabelecida, assim como do lote de triatomíneos alimentado em camundongo. Esses achados sugerem menor potencial biológico para triatomíneos criados por longo tempo em insetário em comparação a novas colônias. Sendo as aves os principais habitantes das palmeiras, a aparente preferência alimentar por sangue de aves demonstrada pela reação de precipitina parece ser circunstancial e não seletiva na busca do sangue com o qual o triatomíneo obteria melhor desenvolvimento.Feeding pattems of R. neglectus collected in palm trees around Belo Horizonte (Minas Gerais, Brazil were investigated. Precipitin tests showed 77.2% of avian blood.

As a control group a colony of R neglectus which has been maintained for several years in the laboratory was also observed. The results show a better development of the “new" colony in comparison with the old one, and of those bugs nourished with mice blood.

    The 2004 reporting to the ISAG comprises 394 plants owned by 256 enterprises. In 2003, reports covered 403 plants owned by 273 enterprises. Waste generation in 2004 is compared to targets for 2008 in the government's Waste Strategy 2005-2008. The following summarises waste generation in 2004: 1) In 2004, total reported waste arisings amounted to 13,359,000 tonnes, which is 745,000 tonnes, or 6 per cent, more than in 2003. 2) If amounts of residues from coal-fired power plants are excluded from statistics, waste arisings in 2004 were 12,179,000 tonnes, which is a 9 per cent increase from 2003. 3) If amounts of residues from coal-fired power plants and waste from the building and construction sector are excluded from statistics, total waste generation in 2004 amounted to 7,684,000 tonnes, which is 328,000 tonnes, or 4 per cent, more than in 2002. In other words, there has been an increase in total waste arisings, if residues and waste from building and construction are excluded. Waste from the building and construction sector is more sensitive to economic change than most other waste. 4) The total rate of recycling was 65 per cent. The 2008 target for recycling is 65 per cent. The rate of recycling in 2003 was also 65 per cent. 5) The total amount of waste led to incineration amounted to 26 per cent, plus an additional 1 per cent left in temporary storage to be incinerated at a later time. The 2008 target for incineration is 26 per cent. These are the same percentage figures as applied to incineration and storage in 2003. 6) The total amount of waste led to landfills amounted to 8 per cent, which is one percentage point better than the overall landfill target of a maximum of 9 per cent landfilling in 2008. Also in 2003, 8 per cent of the waste was landfilled. 7) The targets for treatment of waste from individual sectors are still not being met: too little waste from households and the service sector is being recycled, and too much waste from industry is being

Much of the disposed waste is identified by vague terms, i.e., general plant waste. Attached to this paper is a new waste characterization code devised by the Idaho National Engineering Laboratory to aid in waste volume reduction and stabilization. It is recommended that every facility involved in waste generation and disposal needs to be detailing its wastes to support upgrading of waste management practices. 1 table

    The processing of nuclear waste to transform the liquid waste from fuel reprocessing activities is well defined. Most solid waste forms, if they are cooled and contain diluted waste, are compatible with many permanent storage environments. The public acceptance of methods for disposal is being delayed in the US because of the alternatives studies of waste forms and repositories now under way that give the impression of indecision and difficulty for the disposal of HLW. Conservative programs that dilute and cool solid waste are under way in France and Sweden and demonstrate that a solution to the problem is available now. Research and development should be directed toward improving selected methods rather than seeking a best method, which at best, may always be illusory

    The selection of materials and the design of the blankets for fusion reactors have significant effects upon the radioactivity generated by neutron activation in the materials. This section considers some aspects of materials selection with respect to waste management. The activation of the materials is key to remote handling requirements for waste, to processing and disposal methods for waste, and to accident severity in waste management operations. In order to realize the desirable evnironmental potentials of fusion power systems, there are at least three major goals for waste management. These are: (a) near-surface burial; (b) disposal on-site of the fusion reactor; (c) acceptable radiation doses at least cost during and after waste management operations

    Throughout this century, the application of nuclear energy has produced many benefits, in industry, in research, in medicine, and in the generation of electricity. These activities generate wastes in the same way as do other human activities. The primary objective of radioactive waste management is to protect human health and environment now and in the future without imposing undue burden on future generations, through sound, safe and efficient radioactive waste management. This paper briefly describes the different steps of the management of short lived low and intermediate level wastes, and presents and overview of the state of art in countries involved in nuclear energy, describing their organizations, methodologies used in the processing of these wastes and the final disposal concepts. It also presents the Argentine strategy, its technical and legal aspects. Worldwide experience during the past 50 years has shown that short lived low and intermediate level wastes can be successfully isolated from human and environment in near surface disposal facilities.

    There are three major components which are normally highlighted when the Civilian Radioactive Waste Management Program is discussed - the repository, the monitored retrievable storage facility, and the transportation system. These are clearly the major physical system elements and they receive the greatest external attention. However, there will not be a successful, operative waste management system without fully operational waste acceptance plans and logistics arrangements. This paper will discuss the importance of developing, on a parallel basis to the normally considered waste management system elements, the waste acceptance and logistics arrangements to enable the timely transfer of spent nuclear fuel from more than one hundred and twenty waste generators to the Federal government. The paper will also describe the specific activities the Program has underway to make the necessary arrangements. (author)

    The goal of the DOE Hazardous Waste Program is to support the implementation and improvement of hazardous-chemical and mixed-radioactive-waste management such that public health, safety, and the environment are protected and DOE missions are effectively accomplished. The strategy for accomplishing this goal is to define the character and magnitude of hazardous wastes emanating from DOE facilities, determine what DOE resources are available to address these problems, define the regulatory and operational constraints, and develop programs and plans to resolve hazardous waste issues. Over the longer term the program will support the adaptation and application of technologies to meet hazardous waste management needs and to implement an integrated, DOE-wide hazardous waste management strategy. 1 reference, 1 figure

    The Waste Framework Directive (WFD-2008/98/EC) has set clear waste prevention procedures, including reporting, reviewing, monitoring and evaluating. Based on the WFD, the European Commission and will offer support to Member States on how to develop waste prevention programmes through guidelines and information sharing on best practices. Monitoring and evaluating waste prevention activities are critical, as they constitute the main tools to enable policy makers, at the national and local level, to build their strategic plans and ensure that waste prevention initiatives are effective and deliver behaviour change. However, how one can measure something that is not there, remains an important and unresolved research question. The paper reviews and attempts to evaluate the methods that are being used for measuring waste prevention and the impact of relevant implemented activities at the household level, as the available data is still limited.

    1991-01-01

    The management of radioactive waste is a very important part of the nuclear industry. The future of the nuclear power industry depends to a large extent on the successful solution of the perceived or real problems associated with the disposal of both low-level waste (LLW) and high-level waste (HLW). All the activities surrounding the management of radioactive waste are reviewed. The federal government and the individual states are working toward the implementation of the Nuclear Waste Policy Act and the Low-Level Waste Policy Act. The two congressional acts are reviewed and progress made as of early 1990 is presented. Spent-fuel storage and transportation are discussed in detail as are the concepts of repositories for HLW. The status of state compacts for LLW is also discussed. Finally, activities related to the decommissioning of nuclear facilities are also described

    The incineration process currently seems the most appropriate way to solve the problems encountered by the increasing quantities of low and medium active waste from nuclear power generation waste. Although a large number of incinerators operate in the industry, there is still scope for the improvement of safety, throughput capacity and reduction of secondary waste. This seminar intends to give opportunity to scientists working on the different aspects of incineration to present their most salient results and to discuss the possibilities of making headway in the management of LL/ML radioactive waste. These proceedings include 17 contributions ranging over the subjects: incineration of solid β-γ wastes; incineration of other radwastes; measurement and control of wastes; off-gas filtration and release.

    2010-07-01

    Full Text Available Jouissant dès le début des années vingt d’un grand prestige dû à ses travaux sur les glandes endocrines, le Docteur Gregorio Marañón (1887-1960 s’engagea de tout son poids dans le débat social, mettant son autorité de médecin reconnu au service de la lutte contre la misère. Dans cette même perspective, c’est en endocrinologue convaincu de « l’intelligence vitale » du système hormonal, qu’il prit position en faveur de la limitation des naissances et de la reconnaissance de lasexualité féminine, dans un contexte où cette question était au cœur des conflits idéologiques qui traversaient la société espagnole entre 1920 et 1936. Porté par un important courant de juristes, de médecins, d’écrivains libéraux qui militaient en faveur du birth control et d’une sexualité assumée, le prestigieux docteur Marañón apportait sa légitimité scientifique à la démarche. Or, les thèses de Marañón, promises à une longue et faussement paradoxale postérité sous le franquisme, reposent sur un double postulat qui affirme une certaine forme de déterminisme biologique des comportements humains, et qui affirme aussi, à l’instar des théories freudiennes, l’importance décisive de la sexualité dans ces comportements. On tentera de montrer comment les théories de l’endocrinologue libéral ont pu, dans les années 40, être instrumentalisées pour apporter leur caution scientifique à la morale sexuelle imposée par le franquisme. Les théories de Marañón ont en effet fourni aux intellectuels organiques du régime franquiste tant d’arguments pour sa politique nataliste et pour la relégation des femmes dans le domaine privé du foyer que ses écrits sont incontournables pour quiconque se penche sur cet aspect de l’histoire de la dictature.El Doctor Gregorio Marañón (1887-1960, que gozaba en los años veinte de un gran prestigio debido a sus trabajos sobre endocrinología, se comprometió sin reparos en el

  15. Categorizing operational radioactive wastes

    International Nuclear Information System (INIS)

    2007-04-01

    The primary objective of this publication is to improve communications among waste management professionals and Member States relative to the properties and status of radioactive waste. This is accomplished by providing a standardized approach to operational waste categorization using accepted industry practices and experience. It is a secondary objective to draw a distinction between operational waste categorization and waste disposal classification. The approach set forth herein is applicable to waste generation by mature (major, advanced) nuclear programmes, small-to-medium sized nuclear programmes, and programmes with waste from other nuclear applications. It can be used for planning, developing or revising categorization methodologies. For existing categorization programmes, the approach set forth in this publication may be used as a validation and evaluation tool for assessing communication effectiveness among affected organizations or nations. This publication is intended for use by waste management professionals responsible for creating, implementing or communicating effective categorization, processing and disposal strategies. For the users of this publication, it is important to remember that waste categorization is a communication tool. As such, the operational waste categories are not suitable for regulatory purposes nor for use in health and safety evaluations. Following Section 1 (Introduction) Section 2 of this publication defines categorization and its relationship to existing waste classification and management standards, regulations and practices. It also describes the benefits of a comprehensive categorization programme and fundamental record considerations. Section 3 provides an overview of the categorization process, including primary categories and sub-categories. Sections 4 and 5 outline the specific methodology for categorizing unconditioned and conditioned wastes. Finally, Section 6 provides a brief summary of critical considerations that

    A comprehensive understanding of the quantities and characteristics of the material that needs to be managed is one of the most basic steps in the development of a plan for solid waste management. In this case, the material under consideration is the solid waste generated in healthcare facilities, also known as healthcare waste. Unfortunately, limited reliable information is available in the open literature on the quantities and characteristics of the various types of wastes that are generated in healthcare facilities. Thus, sound management of these wastes, particularly in developing countries, often is problematic. This article provides information on the quantities and properties of healthcare wastes in various types of facilities located in developing countries, as well as in some industrialized countries. Most of the information has been obtained from the open literature, although some information has been collected by the authors and from reports available to the authors. Only data collected within approximately the last 15 years and using prescribed methodologies are presented. The range of hospital waste generation (both infectious and mixed solid waste fractions) varies from 0.016 to 3.23 kg/bed-day. The relatively wide variation is due to the fact that some of the facilities surveyed in Ulaanbaatar include out-patient services and district health clinics; these facilities essentially provide very basic services and thus the quantities of waste generated are relatively small. On the other hand, the reported amount of infectious (clinical, yellow bag) waste varied from 0.01 to 0.65 kg/bed-day. The characteristics of the components of healthcare wastes, such as the bulk density and the calorific value, have substantial variability. This literature review and the associated attempt at a comparative analysis point to the need for worldwide consensus on the terms and characteristics that describe wastes from healthcare facilities. Such a consensus would greatly

    The character, stable or unstable, of a medium can be deduced from the behavior of an ideal model of a semi-infinite medium which is subjected to an excitation only at the boundary. A new analytic method is used to solve this problem. The results obtained show a connection between the character of the medium and certain properties of the dispersion equation, and agree with those derived from other methods. Then, the energy exchange between a medium and a source of excitation is investigated. In order to include the case of growing waves associated with convective instabilities, this problem is treated in the context of the wave packet theory. We find that - even in the absence of collisions - there still is a power exchange. Thus a connexion can be established with the kinematic theories of growing waves and the modes generating power can be found. Moreover, the power absorbed by spatial dispersion is found to be identical with that due to Landau's effect for long waves. This confirms the kinematic character of the latter and bridges a gap between macroscopic and microscopic theories.

    Full Text Available Le travail à domicile s’est développé de manière assez importante au cours des dernières années. Certains le présentent comme une manière de mieux concilier les responsabilités parentales et professionnelles, alors que d’autres y voient une source d’empiètements sur la vie personnelle et familiale. Si un certain nombre d’études s’intéressent aux avantages et inconvénients du télétravail ou du travail à domicile de manière générale, peu se sont penchées sur la dimension temporelle et les perceptions des télétravailleurs à cet égard. Pour notre part, nous avons voulu approfondir cette question. Après avoir constaté que le télétravail à domicile progressait de manière importante dans la population canadienne, nous mettons en évidence un paradoxe, à savoir que si le télétravail peut favoriser la conciliation emploi-famille, il est aussi source d’empiètements dans la vie privée et de brouillage des frontières entre vie privée et vie professionnelle.Telework or home work has developed in an important way over the recent decades. Some consider it as a way to better balance professional and personal or family responsibilities, while others see in it a source of disruption in personal and family life. While some research has looked at advantages and disadvantages of telework from a general point of view, few have analysed in detail the temporal dimension, and the perception of teleworkers concerning these potential temporal conflicts. We wanted to look into this issue on the basis of a few detailed case studies, after having observed that Canadian workers are doing a non negligible number of hours of work at home, and highlight the paradox that while telework has often been put forward for work-life or work-family reasons, it may also invade the private sphere and lead to less clearly defined limits between private and professional life.

Ces recommandations, particulierement Ia seconde, s'ecartent des principes des analyses de surete suivis jusqu'a present en France et a l'etranger; cette etude envisage les avantages et inconvenients potentiels lies a l'introduction de ce second principe. Dans ce but on se base sur differentes analyses realisees au niveau international integrant partiellement au moms ces principes. II ressort de cet examen que ces principes sont applicables mais que leur mise en oeuvre necessite une reorientation de modeles d'evaluation en particulier pour s'affranchir d'hypotheses trop conservatrices. Cette mise en oeuvre necessite par ailleurs davantage d'informations que dans le cas d'une approche deterministe de Ia surete puisqu'il faut estimer les consequences et les probabilites de I'ensemble des evenements possibles et ce pour es diverses modalites de stockage que l'on se propose de comparer. L'integration d'evaluation de ce type est cependant plus riche d'enseignements et constitue de ce fait une aide a Ia decision qui peut etre feconde. On peut enfin souligner que cette approche permet un meilleur dialogue entre les differentes instances decisionnelles et plus generalement entre les acteurs du debat, dans Ia mesure ou elle apporte un langage de discussion commun. On notera d'ailleurs que ce souci de clarification s'exprime quelle que soit I'optique de surete adopte (deterministe ou probabiliste), comme en temoignent les interrogations sur le sens du 'scenario central' de I'etude KBS.

    Waste Treatment Plant (WTP) is designed to provide appropriate systems for processing, immobilization and storage of low and medium radioactive waste arising from the operation of the research facilities of the Nuclear Technology Centre (NTC). It will serve as central collection station processing active waste generated through application of radionuclide in science, medicine and industry in the country. WTP building and structures will house the main waste processing systems and supporting facilities. All facilities will be interconnected. The interim storage building for processed waste drums will be located separately nearby. The separate interim storage building is located near the waste treatment building. Considering the low radiation level of the waste, storage building is large with no solid partitioning walls and with no services or extra facilities other than lighting and smoke alarm sensors. The building will be designed such that drums(200-1)are stacked 3 units high using handling by fork lift truck. To prevent radiation exposure to on-site personnel, the interim storage building will be erected apart from waste treatment plant or other buildings. The interim storage building will also be ready for buffer storage of unconditioned waste waiting for processing or decay and for storage material from the WTP

    The methods of using the energy available in wastes to reduce the energy costs in processes are discussed. Special reference is made to the need for careful evaluation of the potential of the waste to reduce energy costs, before significant investment is made. Problems generally arise due to the effective balancing of the cost of the waste pretreatment with the disposal fee and prime fuel saving. Special reference is made to use of waste as a fuel in the cement industry. Municipal refuse is discussed as a typical successful application.

    This film for a general audience deals with nuclear fuel waste management in Canada, where research is concentrating on land based geologic disposal of wastes rather than on reprocessing of fuel. The waste management programme is based on cooperation of the AECL, various universities and Ontario Hydro. Findings of research institutes in other countries are taken into account as well. The long-term effects of buried radioactive wastes on humans (ground water, food chain etc.) are carefully studied with the help of computer models. Animated sequences illustrate the behaviour of radionuclides and explain the idea of a multiple barrier system to minimize the danger of radiation hazards

    1982-08-01

    The estimation of risks presented by final disposal of radioactive wastes depends, among other things, on what is known of their radioisotope content. The first aim of this report is to present the current state of possibilities for measuring (monitoring) radionuclides in wastes. The definition of a global monitoring system in the framework of radioactive waste disposal has to be realized, based on the information presented here, in accordance with the results of work to come and on the inventory of wastes to be stored. Designed for direct measurement of unpackaged wastes and for control of wastes ready to be stored, the system would ultimately make it possible to obtain all adaquate information about their radioisotope content with regard to the required disposal safety. The second aim of this report is to outline the definition of such a global system of monitoring. Designed as a workbase and reference source for future work by the National Cooperative for the Storage of Radioactive Waste on the topic of radioactive waste monitoring, this report describes the current situation in this field. It also makes it possible to draw some preliminary conclusions and to make several recommendations. Centered on the possibilities of current and developing techniques, it makes evident that a global monitoring system should be developed. However, it shows that the monitoring of packaged wastes will be difficult, and should be avoided as far as possible, except for control measurements

    The guideline of the Ministry for Environmental Protection for controlling radioactive waste with a negligible development of heat defines in detail what data are relevant to the control of radioactive waste and should be followed up on and included in a system of documentation. By introducing the AVK (product control system for tracing the course of waste disposal) the operators of German nuclear power plants have taken the requirements of this guideline into account. In particular, possibilities for determining the degree of radioactivity of radioactive waste, which the BMU-guidelines call for, were put into practice by means of the programming technology of the product control system's module MOPRO.

    Management of Radioactive Wastes is to protect workers and the public from the radiological risk associated with radioactive waste for the present and future. It application of the principles to the management of waste generated in a radioisotope uses in the industry. Any material that contains or is contaminated with radionuclides at concentrations or radioactivity levels greater than ‘exempt quantities’ established by the competent regulatory authorities and for which no further use is foreseen or intended. Origin of the Radioactive Waste includes Uranium and Thorium mining and milling, nuclear fuel cycle operations, Operation of Nuclear power station, Decontamination and decommissioning of nuclear facilities and Institutional uses of isotopes. There are types of radioactive waste: Low-level Waste (LLW) and High-level Waste. The Management Options for Radioactive Waste Depends on Form, Activity, Concentration and half-lives of the radioactive waste, Storage and disposal methods will vary according to the following; the radionuclides present, and their concentration, and radio toxicity. The contamination results basically from: Contact between radioactive materials and any surface especially during handling. And it may occur in the solid, liquid or gas state. Decontamination is any process that will either reduce or completely remove the amount of radionuclides from a contaminated surface

    The purpose of this Design Analysis is to develop preliminary design of the waste package transporter used for waste package (WP) transport and related functions in the subsurface repository. This analysis refines the conceptual design that was started in Phase I of the Viability Assessment. This analysis supports the development of a reliable emplacement concept and a retrieval concept for license application design. The scope of this analysis includes the following activities: (1) Assess features of the transporter design and evaluate alternative design solutions for mechanical components. (2) Develop mechanical equipment details for the transporter. (3) Prepare a preliminary structural evaluation for the transporter. (4) Identify and recommend the equipment design for waste package transport and related functions. (5) Investigate transport equipment interface tolerances. This analysis supports the development of the waste package transporter for the transport, emplacement, and retrieval of packaged radioactive waste forms in the subsurface repository. Once the waste containers are closed and accepted, the packaged radioactive waste forms are termed waste packages (WP). This terminology was finalized as this analysis neared completion; therefore, the term disposal container is used in several references (i.e., the System Description Document (SDD)) (Ref. 5.6). In this analysis and the applicable reference documents, the term ''disposal container'' is synonymous with ''waste package''

Work is being conducted to determine the range of conditions under which these solidification agents can be applied to specific LLW streams. These studies are directed primarily towards defining operating parameters for both improved solidification of problem wastes and solidification of new LLW streams generated from advanced volume reduction technologies. Work is being conducted to measure relevant waste form properties. These data will be compiled and evaluated to demonstrate compliance with waste form performance and shallow land burial acceptance criteria and transportation requirements

    Perry Nuclear Power Plant began developing a waste minimization plan early in 1991. In March of 1991 the plan was documented following a similar format to that described in the EPA Waste Minimization Opportunity Assessment Manual. Initial implementation involved obtaining management's commitment to support a waste minimization effort. The primary assessment goal was to identify all hazardous waste streams and to evaluate those streams for minimization opportunities. As implementation of the plan proceeded, non-hazardous waste streams routinely generated in large volumes were also evaluated for minimization opportunities. The next step included collection of process and facility data which would be useful in helping the facility accomplish its assessment goals. This paper describes the resources that were used and which were most valuable in identifying both the hazardous and non-hazardous waste streams that existed on site. For each material identified as a waste stream, additional information regarding the materials use, manufacturer, EPA hazardous waste number and DOT hazard class was also gathered. Once waste streams were evaluated for potential source reduction, recycling, re-use, re-sale, or burning for heat recovery, with disposal as the last viable alternative

    The purpose of this Design Analysis is to develop preliminary design of the waste package transporter used for waste package (WP) transport and related functions in the subsurface repository. This analysis refines the conceptual design that was started in Phase I of the Viability Assessment. This analysis supports the development of a reliable emplacement concept and a retrieval concept for license application design. The scope of this analysis includes the following activities: (1) Assess features of the transporter design and evaluate alternative design solutions for mechanical components. (2) Develop mechanical equipment details for the transporter. (3) Prepare a preliminary structural evaluation for the transporter. (4) Identify and recommend the equipment design for waste package transport and related functions. (5) Investigate transport equipment interface tolerances. This analysis supports the development of the waste package transporter for the transport, emplacement, and retrieval of packaged radioactive waste forms in the subsurface repository. Once the waste containers are closed and accepted, the packaged radioactive waste forms are termed waste packages (WP). This terminology was finalized as this analysis neared completion; therefore, the term disposal container is used in several references (i.e., the System Description Document (SDD)) (Ref. 5.6). In this analysis and the applicable reference documents, the term ''disposal container'' is synonymous with ''waste package''.

    This report describes the activity based costing method used to acquire variable (volume dependent or avoidable) waste management cost data for routine operations at Department of Energy (DOE) facilities. Waste volumes from environmental restoration, facility stabilization activities, and legacy waste were specifically excluded from this effort. A core team consisting of Idaho National Engineering Laboratory, Los Alamos National Laboratory, Rocky Flats Environmental Technology Site, and Oak Ridge Reservation developed and piloted the methodology, which can be used to determine avoidable waste management costs. The method developed to gather information was based on activity based costing, which is a common industrial engineering technique. Sites submitted separate flow diagrams that showed the progression of work from activity to activity for each waste type or treatability group. Each activity on a flow diagram was described in a narrative, which detailed the scope of the activity. Labor and material costs based on a unit quantity of waste being processed were then summed to generate a total cost for that flow diagram. Cross-complex values were calculated by determining a weighted average for each waste type or treatability group based on the volume generated. This study will provide DOE and contractors with a better understanding of waste management processes and their associated costs. Other potential benefits include providing cost data for sites to perform consistent cost/benefit analysis of waste minimization and pollution prevention (WMIN/PP) options identified during pollution prevention opportunity assessments and providing a means for prioritizing and allocating limited resources for WMIN/PP.

    A prerequisite for future use of nuclear energy in electricity production is safe management of the radioactive wastes generated by nuclear power industry. A number of facilities have been constructed for different stages of nuclear waste management around the world, for example for conditioning of different kind of process wastes and for intermediate storage of spent nuclear fuel. Difficulties have often been encountered particularly when trying to advance plans for final stage of waste management, which is permanent disposal in stable geological formations. The main problems have not been technical, but poor public acceptance and lack of necessary political decisions have delayed the progress in many countries. However, final disposal facilities are already in operation for low- and medium-level nuclear wastes. The most challenging task is the development of final disposal solutions for long-lived high-level wastes (spent fuel or high-level reprocessing waste). The implementation of deep geological repositories for these wastes requires persistent programmes for technology development, siting and safety assessments, as well as for building public confidence in long-term safety of the planned repositories. Now, a few countries are proceeding towards siting of these facilities, and the first high-level waste repositories are expected to be commissioned in the years 2010 - 2020. (author)

    Waste Inspection Tomography (WIT) provides mobile semi-trailer mounted nondestructive examination (NDE) and assay (NDA) for nuclear waste drum characterization. WIT uses various computed tomography (CT) methods for both NDE and NDA of nuclear waste drums. Low level waste (LLW), transuranic (TRU), and mixed radioactive waste can be inspected and characterized without opening the drums. With externally transmitted x-ray NDE techniques, WIT has the ability to identify high density waste materials like heavy metals, define drum contents in two- and three-dimensional space, quantify free liquid volumes through density and x-ray attenuation coefficient discrimination, and measure drum wall thickness. With waste emitting gamma-ray NDA techniques, WIT can locate gamma emitting radioactive sources in two- and three-dimensional space, identify gamma emitting, isotopic species, identify the external activity levels of emitting gamma-ray sources, correct for waste matrix attenuation, provide internal activity approximations, and provide the data needed for waste classification as LLW or TRU.
