    Addressing the question of investment protection currently is of particular importance under the tree aspects: (a) Due to the financial crisis and economic crisis, foreign investment in the years 2008 and 2009 have been drastically reduced; (b) There is a growing critique at the system of international investment protection; (c) For the first time, the Articles 206 and 207 of the Treaty of Lisbon of the European Union show a competence for foreign direct investment. These three aspects seem partly contradictory, but have a considerable changing potential in the area of investment protection. The author of the contribution under consideration describes the tools of investment protection as those are used for raw material projects. Subsequently the author picks out investment protection agreements and deals with some aspects that are important for practical applications in business companies. Raw material projects are projects for the exploration and production of oil and gas in foreign states.

    Full Text Available Background: The purpose of this study was to specify the epidemiological and clinical characteristics of pemphigus in the Department of Dermatology of the University Hospital of Dakar. Patients and Methodology: All medical records of patients seen for pemphigus in our department over a 11-year period were analyzed retrospectively. Results: We collected 105 cases of pemphigus, corresponding to a frequency of 10 cases/year and a hospital prevalence of 2.7%. Thus, pemphigus held the second rank of blistering autoimmune bullous diseases after bullous pemphigoid. The mean age of patients was 47.62 years and the age group [40-59 years] was predominantly affected (28 cases; 45 %. There were 41 femeles and 21 men (F/M ratio: 2. We did not find an endemic focus in our country. Clinical forms were dominated by pemphigus foliaceus (30 cases; 48.5 %, followed by pemphigus vulguaris (19 cases; 30.6 % and finally by pemphigus erythematosus (13 cases; 21%. In 16 cases (25 %, the pemphigus had begun after the consumption of a traditional medicinal plant (8 cases. An associated toxidermia was found in12 cases. Pruritus was present in 43 patients (69.35%. Discussion: In Senegal, pemphigus are common diseases, but without however an endemic focuc. They occur in young women, with a predominance of superficial forms, especially pemphigus foliaceus. The presence of pruritus and associated toxidermia to traditional medicinal plants are common.

    Full Text Available Cet article passe brièvement en revue les relations existant entre la biodiversité des peuplements de poissons et leur fonctionnement écologique. La biodiversité et la structure des peuplements peuvent être décrites, à l'échelle locale, en termes (1 de diversité phylogénétique, (2 de structure des populations, (3 de stratégies démographiques, (4 de diversité morphologique, (5 et de diversité trophique. Un défi majeur est de déterminer les relations qui existent entre la structure des populations et des peuplements et le fonctionnement des peuplements et des écosystèmes. La structure phylogénétique d'un peuplement résulte de l'interaction entre colonisation, extinction et évolution. En dépit du fait que ces facteurs opèrent sur une vaste gamme d'échelles spatiales et temporelles, de grands progrès ont été réalisés dans la modélisation des processus qui sont à la base de la structure génétique et phylogénétique des populations et des peuplements. Les modes de reproduction des poissons sont très variés, et la définition de guildes de reproduction et de stratégies démographiques permet de poser le cadre dans lequel les aspects structurels et fonctionnels peuvent être étudiés. Des études théoriques et empiriques mettent en évidence de fortes relations entre les stratégies démographiques, les variations environnementales et la dynamique des populations. Les poissons présentent une grande diversité morphologique qui, à l'échelle du peuplement, tend à augmenter avec la richesse spécifique. Des relations reliant la morphologie et l'écologie, en termes de fonction et de performance dans l'utilisation du milieu, ont été établies, mais dans certains cas, les tendances prédites sont masquées par des biais d'échantillonnage et la flexibilité du comportement en réponse à la variabilité environnementale.

    Caenepeel, Didier

    This thesis is dedicated to the study of various topological aspects of field theory, and is divided in three parts. In two space dimensions the possibility of fractional statistics can be implemented by adding an appropriate "fictitious" electric charge and magnetic flux to each particle (after which they are known as anyons). Since the statistical interaction is rather difficult to handle, a mean-field approximation is used in order to describe a gas of anyons. We derive a criterion for the validity of this approximation using the inherent feature of parity violation in the scattering of anyons. We use this new method in various examples of anyons and show both analytically and numerically that the approximation is justified if the statistical interaction is weak, and that it must be more weak for boson-based than for fermion-based anyons. Chern-Simons theories give an elegant implementation of anyonic properties in field theories, which permits the emergence of new mechanisms for anyon superconductivity. Since it is reasonable to think that superconductivity is a low energy phenomenon, we have been interested in non-relativistic C-S systems. We present the scalar field effective potential for non-relativistic matter coupled to both Abelian and non-Abelian C-S gauge fields. We perform the calculations using functional methods in background fields. Finally, we compute the scalar effective potential in various gauges and treat divergences with various regularization schemes. In three space dimensions, a generalization of Chern-Simons theory may be achieved by introducing an antisymmetric tensor gauge field. We use these theories, called B wedge F theories, to present an alternative to the Higgs mechanism to generate masses for non-Abelian gauge fields. The initial Lagrangian is composed of a fermion with current-current and dipole-dipole type self -interactions minimally coupled to non-Abelian gauge fields. The mass generation occurs upon the fermionic functional

    Leukaemia is the most common type of cancer in children accounting for about a third of all cancers in children under the age of 15 years. Environmental factors such as non-ionising radiation exposure might play a role in the aetiology of childhood leukaemia. However, data to support such hypotheses are inconsistent. A case control study has been set up in West Germany (University of Mainz) in order to determine whether there is an increased risk of childhood leukaemia in populations exposed to radiofrequency electromagnetic fields from TV and/or Radio towers. Cases are children aged 0 to 14 years with a primary leukaemia diagnosed between 1984 and 2003 who lived in the vicinity of these TV- and/ or Radio towers. Cases have been identified through the German Childhood Cancer Registry. Three controls per case have been individually matched by age at diagnosis, sex, time of diagnosis and study area. The study focuses on an individual retrospective exposure assessment using data from transmitter network operators. The study has started in March 2005 with a pilot investigation in order to specify the study design and the methods for exposure assessment. A total of 2009 eligible cases have been identified. The study will be finished end of 2007. (orig.)

The economic aspects of the main technical problems entailed by these developments are discussed: loading and unloading machines, blowers etc... (authors) [French] Dans une premiere partie, on situe l'interet economique de l'utilisation de l'uranium naturel comme combustible. Cet interet reside a la fois dans le nombre limite et la simplicite relative des operations de mise en forme des elements combustibles, dans le faible cout du produit fini par kwh et dans les immobilisations modestes en capital qu'implique ce cycle par rapport ou cycle de l'uranium enrichi. Tous ces elements permettent de reduire le caractere aleatoire des evaluations des couts, particulierement marque dans le cas de l'uranium enrichi, en raison de la complexite de son cycle et des incertitudes concernant le prix du plutonium. Enfin, la diversite des sources d'approvisionnement en concentre d'uranium naturel opposee au quasi monopole actuel de la separation isotopique, et le faible cout du stockage de ce concentre, offrent des garanties en matiere de securite d'approvisionnement et d'independance economique et politique appreciables par rapport a l'uranium enrichi. En ce qui concerne l'ensemble des capitaux immobilises, on montre que si le cout des centrales au graphite-gaz est plus eleve que celui des centrales eau legere pour certaines gammes de puissance, ce resultat est fortement nuance des que l'on fait intervenir dans un souci d'independance nationale le cout de l'equipement de production des combustibles de l'une et l'autre filiere. Enfin, le cout marginal de la puissance du reacteur au graphite est faible, ses limitations technologiques ont considerablement recule (grace en particulier a l'utilisation du beton precontraint).

    Smart metering comprises more than just meter technology, and the use of information and communication technologies is indispensable. Processes, roles and business models must be reconsidered as further challenges arise in the context of smart metering. For one, there is the operator of the metering points. Secondly, there is the end user who is in the role of an active market partner. Further, there is smart metering as a basic technology, e.g. for smart grids and smart homes. In spite of the need for action, many utilities are reluctant to introduce smart metering. Reasons for this are the cost, a lack of defined standards, and an unclear legal situation. On the other hand, smart metering offers potential for grids and distribution that should be made use of. The authors discuss all aspects of the subject. The point out the chances and limitations of smart metering and present their own experience. [German] Smart Metering geht weit ueber die Zaehlertechnologie hinaus und der Einsatz von Informations- und Kommunikationstechnologien ist unabdingbar. Damit einhergehend muessen Prozesse, Rollen und auch Geschaeftsmodelle neu durchdacht werden. Denn weitere Herausforderungen stehen im direkten Zusammenhang mit Smart Metering. Das ist zum einen die Rolle des Messstellenbetreibers / Messdienstleisters. Das ist zum anderen der Endnutzer, dem die Rolle des aktiven Marktpartners zugedacht wird. Das ist des Weiteren das Smart Metering als Basistechnologie beispielsweise fuer Smart Grid und Smart Home. Trotz des Handlungsdrucks stehen viele Unternehmen der Energiewirtschaft dem Smart Metering zurueckhaltend gegenueber. Drei gewichtige Gruende werden ins Feld gefuehrt: die Kostenfrage, nicht definierte Standards und die in vielen Bereichen ungeklaerte Gesetzeslage. Demgegenueber bietet das Smart Metering Potenziale fuer Netz und Vertrieb, die es zu nutzen gilt.

    Full Text Available La classification, d'après la composition des huiles brutes, permet maintenant de reconnaître des origines semblables ou différentes. Dans certains cas, les corrélations non seulement entre indices et accumulations, mais entre roches mères et accumulations sont devenues sûres. L'étude, selon un fil logique du devenir des composés de la matière organique vivante, morte, fossilisée puis diagénisée, a permis de préciser l'origine organique des pétroles mais encore de lier la composition de ceux-ci aux types dominants de matière organique des bassins sédimentaires, donc de fixer les conditions de sédimentation, les environnements les plus favorables à l'accumulation et la préservation de matière organique pétroligène. Cependant, la contribution la plus importante de la géochimie organique à l'exploration est certainement d'avoir pu fixer, dans un premier temps, une fourchette de température, puis de température et de durée : le facteur thermo-temporel de naissance de production maximale puis de conservation des hydrocarbures liquides : la fenêtre à huile potentielle. Plus récemment la géochimie des gaz hydrocarburés a pu montrer que cette fenêtre à huile était encadrée par la génération de gaz légers. Ce développement récent remet en valeur des objectifs de prospection abandonnés ou classés sans intérêt. Cependant par essence même la géochimie organique, comme la majorité. des sciences qui utilisent le laboratoire, donne des résultats ponctuels : ceux-ci ne trouvent toute leur signification que si les échantillons géologiques sont bien situés dans la configuration géologique à laquelle ils appartiennent. Organic geochemistry has made great strides, thanks in particular to the range of analytical tools, often in the forefront of technological progress, which have been developed for medical and biochemical research.

    The project aims at identifying the energy impact of various current ways of regional planning through a case study of eight districts in the canton of Neuchatel. The districts reveal the trends of planning in an urban centre, and in incorporated (suburb) or unincorporated territory. Thus, the influence of the distance to the centre of the agglomeration named 'centrality' has been studied. The energy expenditure for the buildings' construction phase (buildings, roads, networks) and utilization phase (heating, electricity, water, waste, networks) has been taken into account as well as the mobility. The energy investments have been evaluated by the method SNARC. The energy expenditure for operation and mobility has been evaluated based on questionnaires addressed to the inhabitants. As a result, the variable 'centrality' has only a weak role on the life cycle analysis (LCA) per inhabitant. In our case, the LCA for incorporated districts (suburb) and unincorporated districts are similar. With a LCA per square meter, the impact is completely similar and no correlation with the variable 'centrality' has been noticed. As the households are larger per inhabitants when the district is located in a suburban zone, the LCA per square meter remains stable. On the contrary, if the LCA is determined per household, the LCA is perfectly correlated with the variable 'centrality'. Thus, a household in the centre of Neuchatel consumes twice less energy resources than a household in Val-of-Ruz (rural area). The study highlights also the critical impacts of a LCA on a district scale. Finally, this study gives recommendations based on the energy and demographic prospects in order to respond to the objective of a 2000 watts society. (author)

    Summary La brûlure est un accident qui reste toujours très fréquent au Maroc, ce qui fait d'elle un problème de la santé publique. Les brûlures, quand elles sont graves ou profondes, entraînent de façon quasi inéluctable des séquelles fonctionnelles et esthétiques. A travers deux observations de deux enfants présentant des séquelles de brûlures graves, ayant retenti péjorativement sur leurs scolarités, on a essayé de mettre en évidence quelques facteurs incriminés dans cette tragédie (feu, petites bouteilles de gaz et le manque d'infrastructure, du personnel médical et paramédical, du matériel ainsi que de la prévention) comme étant une grande cause dans la survenue de ces séquelles. Le but de notre travail est d'énumérer ces différents facteurs intriqués, ainsi que de proposer quelques solutions, tout en insistant sur la prévention. PMID:21991156

    Radiation safety in conventional X-ray diagnostics is based on the concepts of justification, optimization of an X-ray examination and limitation of the radiation exposure achieved during the examination. Optimization of an X-ray examination has to be considered as a multimodal process in which all technical components of the X-ray equipment have to be adapted to each other and also have to be adapted to the anthropometric characteristics of patients and the clinical indications. In this article the technical components of a conventional pediatric chest X-radiograph are presented, and recommendations for optimizing chest X-rays in children are provided. The following measures are of prime importance: correct x-ray beam limitation, using the posteroanterior projection when possible and not using anti-scatter grids in children under approximately 8 years old. In pediatric radiology chest x-rays that are taken not at the peak of inspiration can also be of some diagnostic significance. Optimization of an X-ray examination inevitably results in the limitation of radiation exposure. (orig.)

    Chronic adrenal insufficiency, known as Addison's disease, presents with a constellation of symptoms and signs. The neuropsychiatric aspect of this condition is not fully understood and not much has been documented about it in the English literature. This article presents a case of a 41-year old male patient who presented initially with depression after a recent life stressor. After his condition escalated and therapy continued to fail, the medical team revised its diagnosis to Addison's disease. Neuropsychiatric symptoms could be the first presentation of Addison's disease, and thus should be kept in mind whenever such a case presents to the physician.

    A deep gap, reflecting a persisting fear, separates the viewpoints of the experts and that of the public on the issue of the disposal of nuclear WASTES. The history of this field is that of the proliferation with time of spokesmen who pretend to speak in the name of the both humans and non humans involved. Three periods can be distinguished: 1940-1970, an era of contestation and confusion when the experts alone represents the interest of all; 1970-1990, an era of contestation and confusion when spokespersons multiply themselves, generating the controversy and the slowing down of most technological projects; 1990-, an era of negotiation, when viewpoints, both technical and non technical, tend to get closer and, let us be optimistic, leading to the overcome of the crisis. We show that, despite major differences, the options and concepts developed by the different actors are base on two categories of resources, namely Nature and Society, and that the consensus is built up through their `hydridation`. we show in this part that the perception of nuclear power and, in particular of the underground disposal of nuclear wastes, involves a very deep psychological substrate. Trying to change mentalities in the domain by purely scientific and technical arguments is thus in vain. The practically instinctive fear of radioactivity, far from being due only to lack of information (and education), as often postulated by scientists and engineers, is rooted in archetypical structures. These were, without doubt, reactivated in the 40 s by the traumatizing experience of the atomic bomb. In addition, anthropological-linked considerations allow us to conclude that he underground disposal of wastes is seen as a `rape` and soiling of Mother Earth. This contributes to explaining, beyond any rationality, the refusal of this technical option by some persons. However, it would naturally be simplistic and counter-productive to limit all controversy in this domain to these psychological aspects

    This paper reviews the experience acquired in France on the question, of reactor safety. Since a special paper is being presented on reactors of the graphite gas type, the safety of the other types studied in France is discussed here: - heavy water-gas reactors, - fast neutron reactors, - water research reactors of the swimming-pool and tank types. The safety rules peculiar to the different types are explained, with emphasis on their influence on the reactor designs and on the power limits they impose. The corresponding safety studies are presented, particular stress being placed on the original work developed in these fields. Special mention is made of the experimental systems constructed for these studies: the reactor CABRI, pile loop for depressurization tests, loops outside the pile, mock-ups etc. (authors) [French] La presente communication propose une synthese de l'experience acquise en France en matiere de surete des reacteurs.

    The economic advantage of electricity-generating nuclear stations decreases when their size decreases. However, when a counter-pressure turbine is joined on to a reactor and the residual heat can be properly used, it can be shown that fairly low capacity nuclear equipment may compete with conventional equipment under certain realistic enough conditions. The aim of this paper is to define these special conditions under which nuclear energy can be profitable. They are connected with the location and the general economic environment of the station, the pattern of the electricity and heat demands it must meet, the level of fuel and specific capital costs, nuclear and conventional. These conditions entail certain technical and economic specifications for the reactors used in this way otherwise they are unlikely to be competitive. In addition, these results are referred to the potential steam and electricity market, which leads us to examine certain uses for the heat generated by double purpose power stations; for example, to supply combined industrial plants, various types of town heating and for removal of salt from sea water.

    Full Text Available Bien que les aspects hydrodynamiques soient d'une importance primordiale lors de la conception et du fonctionnement d'un réacteur gaz-liquide-solide à lit fixe arrosé, les méthodes de calcul prédictif proposées sont restées fort rudimentaires. La plupart des études portant sur ce sujet ont été menées dans des conditions quasi atmosphériques alors que les réacteurs industriels fonctionnent à des pressions élevées. C'est seulement récemment que quelques résultats expérimentaux ont été obtenus à des hautes pressions, et des corrélations ont été proposées dans ces conditions pour prédire la transition entre les régimes ruisselant et pulsé, la perte de pression et le taux de rétention de liquide. L'objectif de cet article est double. D'une part, une synthèse y est présentée ; elle fait état des connaissances acquises sur les divers aspects hydrodynamiques du réacteur triphasique à lit fixe, incluant les récents développements réalisés à hautes pressions. D'autre part, les modèles et les corrélations actuels de transitions de régimes, de la perte de pression et du taux de rétention de liquide sont soumis à une analyse critique en confrontant leurs prédictions à l'ensemble des données expérimentales obtenues pour un large intervalle de la pression de fonctionnement du réacteur. Des conclusions objectives ont pu être tirées concernant les aptitudes des corrélations et des modèles actuels à être utilisées pour les calculs de conception des réacteurs triphasiques à lit fixe industriels. Malheureusement, il apparaît qu'aucun modèle de transitions entre les régimes ruisselant et pulsé n'est satisfaisant. Seule la corrélation empirique de Larachi et al. (1993 s'avère être jusqu'à présent la méthode la plus précise pour prédire la position de la frontière entre les régimes ruisselant et pulsé dans un large domaine de la pression de fonctionnement.

    plusieurs types de dérivés sulfurés et/ou phosphorés sera parfois nécessaire. Enfin, des additifs complémentaires : anticorrosion, en particulier pour protéger les métaux cuivreux, antirouille, antimousse, réducteur de frottement seront sélectionnés en évitant des interactions préjudiciables aux performances mécaniques. La formulation d'additifs destinés aux lubrifiants extrême-pression pour engrenages nécessite donc un choix judicieux des composants de sorte que chacun d'entre-eux puisse assumer correctement sa fonction pour une durée aussi longue que possible. Optimal conditions for engine efficiency rarely correspond to the needs of the end use of energy insofar as rpm and torque are concerned. This is why intermediary mechanisms are needed for making the necessary adjustments, i. e. reducing gears, gear boxes (manual or automatic, transfer cases and rear axles. Modern technology, particularly for transportation, requires the reduction of both the mass and volume of such mechanisms, meaning that greater and greater specific loads must pass through gears. Despite technological progress made in designing and manufacturing gears, their proper lubrication remains a determinant factor. The lubrication of heavily loaded gears requires the use of chemical components called extreme-pressure additives . Among them, phosphorus and sulfur combinations are widely used in industry and will be the only ones considered in this article. Sulfur is the element most often used to obtain extreme-pressure properties. It forms an easily sheared film of iron sulfide on microweldings. Sulfur is present in oil as organic sulfides or polysulfides, but its lability must be adjusted to have a solely local effect without causing any corrosion. A good understanding of the relations between the structure and mechanical properties of polysulfides is required for optimizing the structure of industrial additives. Antiwear properties are usually provided by phosphorus compounds, i. e

    Reasonably complete knowledge of the phonon dispersion curves for at least a dozen metallic elements and intermetallic compounds has now been obtained from neutron inelastic scattering experiments. The results have one feature in common: when analysed in terms of interatomic force constants they reveal the presence of comparatively long-range forces extending over several atomic spacings. The results for lead are particularly interesting; it did not prove possible to fit them by a force-constant model, but the dispersion curves for wave vectors in symmetry directions when analysed in terms of force constants between planes of atoms showed an oscillatory interatomic potential extending over distances of more than 20A. This review is concerned with recent theoretical work which has a bearing on the calculation of phonon dispersion curves for metals and the explanation of the long range of the interatomic potential. The best hope at present for a general treatment of atomic interaction in metals appears to lie in the ''method of neutral pseudo-atoms'', (a description recently coined by Ziman). This approximate theory is outlined and its relevance to Kohn anomalies in phonon dispersion curves is discussed. Experimental data for sodium is consistent with the theory, and the interatomic potential in sodium varies periodically in a distance {pi}/k{sub F}, where fik{sub F} is the Fermi momentum, as has already been demonstrated by Koenig in a different way. More exact calculations have been made for sodium by Toya and by Sham. The relationship between the different methods and other work of a more general character such as that of Harrison are discussed.

  13. Tense, Aspect and Case in Bantu and significance in Translation- The Case of Lulogooli Bible

    Full Text Available Tense and Aspect are morphological features and in some languages like English, they are marked mainly by inflection on the verb. In Bantu languages, the verbal element is characteristically conflated to mark tense and aspect and more often than not, the morphemes marking tense and aspect cannot be isolated. In many instances, they are tonally marked. Thus, a lexical verb may mark three or even more distinctions whose semantic realization is only through tonal variation. Similarly, Case realization is unique compared to for example English that marks possession on the noun and gender distinction on pronouns. This study will examine these features in Lulogooli, a Bantu language spoken in Western Kenya. Lulogooli has only two gender distinctions; male and female but does not use pronouns to mark them. This study proposes to sample data from the Lulogooli bible translation to show why and how improper use of these three grammatical categories leads to mistranslation. The analysis will also contribute to the significance of understanding language typology to translators so as to aid accuracy and effectiveness in translation. The study posits the significance of aspects of linguistic analysis to translation.

    Bilateral exostosis of the 5th rib was observed in a 6-year-old fluorotic cow. Besides a radiological hyperostotic aspect, microradiographic analysis showed signs of bone destruction as well as exuberant subperiosteal and endosteal bone formation. From these observations, it may be concluded that fluoride lead not only to a spontaneous fracture of the rib but also to an exaggerated callus formation

    Full Text Available On examine dans cet article différentes approches de la thermodynamique des solutions de polymères placées dans leur contexte historique. On rappelle d'abord le modèle du réseau de Flory-Huggins et on en souligne les déficiences. On traite ensuite brièvement de la mécanique statistique des solutions de polymères introduite par Prigogine en 1957 et on montre qu'elle constitue un progrès qualitatif par rapport à la théorie du réseau, mais qu'elle ne prévoit cependant pas de manière quantitative les propriétés de ces solutions. On montre ensuite que le concept de volume libre, qui permet un traitement simplifié de certaines quantités, permet également d'expliquer tout naturellement l'existence d'une deuxième température de séparation en phase lorsque l'on élève la température, propriété qui différencie les solutions de polymères des mélanges de liquidés simples. Enfin, dans une dernière partie, on mentionne brièvement les travaux récents de l'École de Paris, qui traite les solutions de polymères par analogie avec les transitions magnétiques. This article examines différent approaches ta the thermodynamics of polymer solutions set in their historical context. First of all, the Flory-Huggins network model is described and ifs deficiencies are pointed out. Then attention is briefly drawn to the statistical mechanics of polymer solutions as introduced by Prigogine in 1957, and this mechanics is shown to be a qualitative advance compared with the network theory, but it nonetheless does not quantitatively predict the properties of such solutions. It is then shown that the concept of free volume, enabling some quantifies to be treated in a simplified way, also serves to provide a quite natural explanation for the existence of a second phase separation temperature when the temperature is raised, i. e. a property that differentiates polymer solutions from simple liquid mixtures. In the final part, brief mention is made

    Pancreatic cancer is a highly malignant disease and despite progress in systemic therapy survival is still short. For patients with R0/R1 resected disease, adjuvant chemotherapy with gemcitabine has been established as the standard treatment. More controversy exists with regard to optimal treatment of locally advanced non-metastatic pancreatic cancer. However, there is evidence to suggest that patients who respond to an initial phase of chemotherapy may be those who benefit most from sequential chemoradiotherapy. Specifically, in the treatment of advanced and metastatic disease chemotherapy or radiotherapy cannot stand alone but must be accompanied by multidisciplinary treatment approaches involving pain management, weight control, psychooncological care and palliative care. Monotherapy with gemcitabine and the combined use of gemcitabine with erlotinib are established standards for treatment of metastatic pancreatic cancer. Patients in a good general condition but where the gemcitabine-based therapy failed should be offered second-line treatment. (orig.) [German] Das Pankreaskarzinom ist eine hochmaligne Erkrankung, die trotz nachweisbarer klinischer Fortschritte weiterhin mit einem meist kurzen Ueberleben verbunden ist. Bei R0/R1-resezierten Patienten gilt eine adjuvante Behandlung mit Gemcitabin gegenwaertig als etablierter Behandlungsstandard. Weniger eindeutig ist die optimale Therapie des lokal fortgeschrittenen, nichtmetastasierten Pankreaskarzinoms (LAPC). Es gibt aber Hinweise dafuer, dass Patienten, die auf eine initiale Chemotherapiephase ansprachen, von einer nachgeschalteten Radiochemotherapie profitieren koennen. Gerade zur Behandlung des metastasierten Pankreaskarzinoms sollten die Chemo- oder die Radiochemotherapie nicht allein stehen, sondern durch multidisziplinaere Behandlungsansaetze unterstuetzt werden. Dazu gehoeren die Schmerz- und Ernaehrungstherapie, Psychoonkologie und Palliativmedizin. Bei der Behandlung des metastasierten

    Wolfram syndrome is an autosomal recessive disorder caused by mutations in the WFS1 gene. Clinical heterogeneity has been reported both within and between families with WFS1 mutations. The first case was diagnosed with insulin-dependent diabetes mellitus with positive for pancreatic autoantibodies and had a ketoacidotic attack in the follow-up period. The second case presented initially with optic atrophy and was diagnosed with behavioral and psychiatric problems at an early age. The third case had early onset insulin-dependent diabetes with multiple anomalies and congenital hypothyroidism. Many of these features have not been reported previously in patients with Wolfram syndrome. In all three patients homozygous mutations in WFS1 were identified. Wolfram syndrome is a disease where the characteristic features may present at different times. A diagnosis of Wolfram syndrome should therefore be considered even in the absence of the full spectrum of clinical features.

    Introduction Le strabisme est défini comme un syndrome à double composante: motrice et sensorielle. Le but de ce travail est de décrire les aspects épidémiologiques et cliniques du strabisme chez l'enfant congolais de 0 à 15 ans dans la ville de Lubumbashi. Méthodes Il s'agit d'une étude descriptive longitudinale sur les aspects épidémiologiques et cliniques du strabisme chez l'enfant congolais de 0 à 15 ans dans la ville de Lubumbashi entre Décembre 2012 à Décembre 2013. Nous avons recueilli l’âge des patients, leur sexe, leur provenance, le type de strabisme, la réfraction, le fond d'oeil, les antécédents (hérédité) ainsi que le type de la déviation strabique observé sur 70 patients. Résultats Nous avons observé 70 cas de strabisme manifeste dont 31 cas (44,28%) étaient dans la tranche d’âge comprise entre 0 et 5 ans. L’âge moyen de nos patients était de 6,7 ans avec une prédominance du sexe féminin, soit 51,42%. Le strabisme était convergent dans 65,71%, divergent dans 30%, et vertical dans 4,28%. Les ésotropies représentaient 65 cas (92,85%), quatre cas (5,71%) avaient un antécédent familial de strabisme au premier degré de parenté, 21 cas (30%) au second degré de parenté, 45 cas (64,28%) n'avaient pas cet antécédent. L'oeil gauche était le plus dominé dans 30% des cas. Les facteurs favorisant le strabisme étaient inconnus dans 54 cas (77,14%). Le strabisme était secondaire à l'hypermétropie chez 32 patients (42,71%). Conclusion La fréquence du strabisme dans la ville de Lubumbashi chez les enfants âgés de 0 à 15 ans est de 0,50%. Comme dans la plupart des études sur le strabisme de l'enfant, c'est l’ésotropie qui est la déviation la plus commune. PMID:26834919

    To-day very reliable irradiation equipment is available, and for an industrialist it is largely an economic consideration whether he should go in for an otherwise acceptable irradiation processing. In Denmark an industrial concern has now found it economically justifiable to establish a multi-purpose industrial plant, equipped with an American linac, and this facility will be able to process food.l To date, few plants in the world have recorded actual cost experiences for industrial food processing, but cost figures from other fields may serve as a guide. In practical calculations it is convenient to divide the work into certain typical groups, e.g. facilities for ''bulk'', ''medium'', ''thin'', and ''multi-purpose'', but food products may come under any of these headings. Costs of irradiation depend on product properties, type of plant, annual and monthly quantities, doses, control standards, special requirements for re-packing or other additional handling, etc. Definite figures for a particular case must be based on an exact calculation, but for a preliminary judgement many general price-range indications are available to the industrialist, and for a variety of purposes it is already evident that irradiation processing is economically sound. Apart from plant economy it is advisable for the industrialist to study some general commercial problems also, such as consumer preference and marketing structure, for the commodity in question. This can often best be done by marketing a pilot production of some quantity, before final decisions are taken regarding major investments in highly-specialized equipment. For some products market testing has already been done with good results by existing research or production facilities, and indeed actual commercial marketing has been reported. In conclusion, many food irradiation processes seem to be promising from an economic point of view. (author) [French] Il existe actuellement un materiel d'irradiation parfaitement sur et

  5. Plastic surgery in chest wall reconstruction: relevant aspects - case series

    Directory of Open Access Journals (Sweden)

    Diogo Franco

    Full Text Available Objective: to discuss the participation of Plastic Surgery in the reconstruction of the chest wall, highlighting relevant aspects of interdisciplinaryness. Methods: we analyzed charts from 20 patients who underwent extensive resection of the thoracic integument, between 2000 and 2014, recording the indication of resection, the extent and depth of the raw areas, types of reconstructions performed and complications. Results: among the 20 patients, averaging 55 years old, five were males and 15 females. They resections were: one squamous cell carcinoma, two basal cell carcinomas, five chondrosarcomas and 12 breast tumors. The extent of the bloody areas ranged from 4x9 cm to 25x40 cm. In 12 patients the resection included the muscular plane. In the remaining eight, the tumor removal achieved a total wall thickness. For reconstruction we used: one muscular flap associated with skin grafting, nine flaps and ten regional fasciocutaneous flaps. Two patients undergoing reconstruction with fasciocutaneous flaps had partially suffering of the flap, solved with employment of a myocutaneous flap. The other patients displayed no complications with the techniques used, requiring only one surgery. Conclusion: the proper assessment of local tissues and flaps available for reconstruction, in addition to the successful integration of Plastic Surgery with the specialties involved in the treatment, enable extensive resections of the chest wall and reconstructions that provide patient recovery.

    Eating epilepsy is an uncommon form of reflex epilepsy. The authors present a case report of a patient with clinical diagnosis of eating epilepsy who was submitted to clinical tests, neuroimaging studies (MRI and SPECT) and surface EEG. Multiple intercritical EEGs showed sharp discharges in the posterior left temporal area. The MRI did not show any abnormality. The intercritical brain SPECT showed clear hypoperfusion in the posterior left temporal area; so confirming the epileptogenic focus in producing the partial complex seizures triggered by eating.

    The transformation of the energy system to a de-carbonized energy supply requires a coordinated interaction between the sectors electricity, heat and transport. Thereby, the coupling of the electricity sector with the heating sector is one of the key measures in the transformation. The inclusion of wind and solar energy in the grid can be optimized by exact feed in forecasts, the coupling to the heat sector by means of heat pumps and power-to-heat (heater) allows more flexibilisation of the demand side. This interaction is made possible by intelligent solutions of systems engineering and power management. The development of appropriate incentives, market mechanisms and business models is also required, to make this coupling also economic successful. The contribution present die 80% scenario for the year 2050 created in the research project ''Interaction RES electricity, heat and transport'' and gives examples of future requirements and developments on this topic.

Die Aufnahme von Wind- und Sonnenenergie in das Netz kann durch genaue Einspeiseprognosen optimiert werden, die Kopplung zum Waermesektor mittels Waermepumpen und Power-to-Heat (Heizstab) ermoeglicht die weitere Flexibilisierung der Nachfrageseite. Diese Interaktion wird durch intelligente Loesungen der Systemtechnik fuer das Energie- und Netzmanagement ermoeglicht. Die Entwicklung von entsprechenden Anreizsystemen, Marktmechanismen und Geschaeftsmodellen ist ebenfalls erforderlich, um diese Kopplung auch wirtschaftlich erfolgreich zu gestalten.

    Full Text Available Background. Huntington disease occurrs rarely, it can be encountered not only by neurologists and psychiatrists but also by other medical practitioners. Its characteristic features are involuntary movements, cognitive disorders and gradual development of dementia. Diagnosis is given on the basis of these clinical features, positive familial anamnesis, with the laboratory exclusion of other neuropsychiatric diseases and with the help of neuroimaging methods (in particular NMR. The disease can be only confirmed by means of genetic analysis.Patients and methods. In this article, four cases of patients with Huntington disease and diverse psychiatric disorders that were hospitalised at the psychiatric department of the Maribor General Hospital between October 2002 and March 2003 are described. All the patients fulfilled the valid criteria for the diagnosis of Huntington disease. However, they differed according to their accompanying psychiatric psychopathology, age and social problems.Conclusions. The purpose of this article is to draw attention to different psychiatric symptoms and clinical manifestations of Huntington disease that are often misleading in the diagnostic process. In addition, exigency of early diagnostics, guidelines for referrals to genetic testing and psychiatric monitoring of these patients are emphasised.

    The hematological aspects of the original case of Rhmod are reported. The subject, as in other reported cases, had a chronic hemolytic anemia characterized by stomatocytosis, reduced osmotic fragility, and abnormal autohemolysis correctable with the addition of glucose. The 51 Cr red cell survival studies showed the spleen to be the preferential site of red cell destruction and splenectomy produced a dramatic improvement in red cell survival. The topic of Rh deficiency syndrome (Rhnull and Rhmod) is briefly reviewed with regard to the number of cases reported, to genetic aspects, to the hematological findings, and to the results of splenectomy

    A case study into the preparation and physiological responses of competing in the Marathon des Sables (MDS) was conducted by preparing a male competitor for, and monitoring him during, his first attempt at the race. The aims of this case report were to (a) prepare and monitor an ex-Olympic, male rower (S1) during the 2010 race and; (b) compare his physiological responses and race performance to that of the current MDS record holder (S2). S1 (age 37 y; body mass 94.0 kg; height 1.92 m; VO(2peak) 66.0 ml·kg⁻¹·min⁻¹) and S2 (age 37 y; body mass 60.8 kg; height 1.68 m; VO(2peak) 65.9 ml·kg⁻¹·min⁻¹) completed a heat test and S1 subsequently underwent 7 d of heat acclimation prior to the MDS. Gastro-intestinal temperature (Tgi) and heart rate (HR) were measured for S1 during Stages 2, 4, and 5 of the MDS and pre- and post-stage body mass, and urine specific gravity were measured for all stages. Race time and average speeds were collected for S1 and S2. Total race times for S1 and S2 were 25:29:35 and 19:45:08 h:min:s. S1's mean (± 1 SD) percentage HR range (%HRR=[HR-HRmin]/[HRmax-HRmin]x100) was 66.1 ± 13.4% and Tgi ranged between 36.63-39.65°C. The results provide a case report on the physiological responses of a highly aerobically-trained, but novice ultra-endurance runner competing in the MDS, and allow for a comparison with an elite performer.

    The French Meteorological Society (SMF) organized its annual scientific day on March 23, 2011 on the topic of the multiple aspects of climate change. The aim was to take stock of the lessons learnt from the different meteorological markers in several domains (agriculture, forests, ecosystems, rise of sea level, changes in marine biodiversity, health, snow and ice caps..). This paper summarizes the seven presentations given at this meeting: 1 - climate change today and tomorrow (H. Le Treut); 2 - rise of oceans level: estimations and regional variability (G. Woeppelmann); 3 - polar caps and continental cryo-sphere as seen from space (A. Kouraev, F. Remy and E. Berthier); 4 - impact of climate change on exploited marine populations: projections and uncertainties (P. Lehodey); 5 - stakes of climate change on agricultural and winery activities in France (E. Duchene); 6 - impact of climate change on forest trees phenology and consequence on their survival and operation (F. Lebourgeois, I. Chuine and M. Vennetier); 7 - 'tele-epidemiology': a health-aid in a climate change context. (J.S.)

    Full Text Available La migration du pétrole vers les réservoirs et les pièges, et particulièrement son expulsion hors de la roche-mère où il s'est formé (migration primaire, est demeurée longtemps un des problèmes les plus mal connus de toute la géologie pétrolière. Le déplacement du pétrole et du gaz s'effectue en phase hydrocarbure séparée. L'eau, souvent considérée comme le véhicule du pétrole dans la migration, joue en fait un rôle négatif : il faut que la saturation en eau ait suffisamment diminué (par expulsion et que la saturation en hydrocarbures ait suffisamment augmenté (par génération à partir du kérogène pour que l'écoulement d'une phase hydrocarbure devienne possible. Le moteur de cette expulsion est le gradient de pression : l'élévation de la pression dans l'espace poreux des roches-mères résulte de trois causes (la charge sédimentaire, la genèse des hydrocarbures, et l'expansion thermique de l'eau. La microfissuration, qui survient quand la pression interne des fluides dépasse la résistance mécanique de la roche peut jouer un rôle important. Les observations dans les bassins sédimentaires de cas bien documentés sont encore trop rares. Il est, en particulier, difficile de calculer les réserves mobilisées à l'échelle d'un permis ou d'un bassin. La modélisation numérique de la migration, associée à celle de la genèse du pétrole et du gaz, offre des perspectives dans ce sens, mais elle demande encore des travaux complémentaires. Parmi les conséquences de la migration, on peut citer : la possibilité de corrélation huile/roche-mère, la teneur plus faible en produits lourds dans les réservoirs que dans les roches-mères et le rôle souvent joué par un déplacement où hydrocarbures liquides et gazeux forment une phase unique, qui migre en laissant progressivement derrière elle les fractions plus lourdes, par condensation rétrograde. Oil migration toward reservoirs and traps, and especially its

    Full Text Available Parmi les méthodes utilisées en vue de la définition des potentialités viticoles, l'approche intégrée des terroirs fondée sur la notion de séquence écogéopédologique développée en Moyenne Vallée de la Loire par l'INRA d'Angers s'est révélée particulièrement performante. Son application à la caractérisation du vignoble d'Alsace, fondamentalement différent sur le plan de sa structure géologique, nécessite un certain nombre d'aménagements méthodologiques liés à une variabilité paysagère marquée. Ainsi, une typologie des paysages s'appuyant sur des paramètres tels que l'ouverture du paysage, la répartition et l'orientation des masques est proposée. Elle vient compléter les descripteurs stationnels classiques (altitude, pente et exposition. Le concept de séquence écogéopédologique reste pertinent dans ce contexte moyennant l'adjonction du paramètre exposition, dans le cas des terroirs sur versants. Dans cette optique, les caractéristiques des composantes naturelles des grands types de terroirs alsaciens sont présentées à partir de l'étude de cas concrets.

    Introduction L'objectif de notre étude était de décrire les caractéristiques sociodémographiques et les Facteurs de Risque cardio-Vasculaires (FRV) des patients admis pour accidents vasculaires cérébraux (AVC) dans un service autre que celui de la neurologie. Méthodes Étude transversale rétrospective sur une période de 2 ans (janv. 2010 et déc. 2011), réalisée aux urgences de l'institut de cardiologie d'Abidjan. Résultats Il s'agissait de 176 adultes avec un âge moyen de 60 ans, une prédominance féminine. Les facteurs de risque majeurs retrouvés étaient l'hypertension artérielle dans 86,4% des cas, le diabète dans 11,4% des cas, le tabagisme dans 2,2% des cas. Les motifs de consultation étaient la perte de connaissance dans 36,4% des cas, l'hémiplégie dans 31,8% des cas, les céphalées dans 17,4% des cas, les vertiges dans 10,9% et les palpitations dans 2,2% des cas. La tension artérielle systolique moyenne était à 174 mmHg, la tension artérielle diastolique moyenne était à 105 mmHg et la pression pulsée moyenne était à 70 mmHg. Les AVC étaient associés à une arythmie complète par fibrillation auriculaire dans 11,4% des cas. Les AVC ischémiques représentaient 84,1%. L’évolution aux urgences a été marquée par un décès dans 17% (30) des cas. Conclusion Les AVC constituent un problème majeur de santé publique. Malgré sa prédominance féminine, ils (AVC) touchaient 44% des hommes dans notre étude lorsqu'on sait qu'en Afrique l'activité sociale repose sur les hommes. Ils restent une pathologie grave par la forte létalité. PMID:26327997

    Full Text Available L'injection de gaz carbonique dans les gisements pétroliers a donné lieu depuis une quinzaine d'années à de très nombreuses études de laboratoire et sur modèles. De multiples pilotes ont été réalisés et quelques projets industriels sont en cours. II est donc intéressant de faire un bilan des connaissances et de l'expérience ainsi acquise, afin de tenter de dégager les perspectives de développement du procédé. La première partie rappelle le comportement du CO2 en présence d'hydrocarbures et les principaux mécanismes d'action dans le processus de récupération. On examine ensuite dans une deuxième partie les principales applications pilotes ou industrielles et les problèmes opérationnels rencontrés. Ce bilan permet de dégager les caractéristiques principales du procédé, les difficultés essentielles rencontrées. Un aperçu est donné sur les recherches en cours en vue de résoudre ces difficultés et améliorer le procédé. La dernière partie s'attache à préciser les perspectives d'application de l'injection de CO2 et pour cela trois aspects essentiels pour le développement du procédé sont discutés : les performances et le domaine d'emploi, la disponibilité et le coût des différentes sources potentielles de CO2 et enfin l'évaluation économique du procédé. The injection of carbon dioxide into oil fields has been the subject of extensive laboratory and modeling research for the last 15 years. Many pilot experiments have been performed, and several industrial projects are under way. Therefore it is interesting to review the state-of-the-art of the know-how and experience thus acquired so as to try to determine the outlook for the development of the process. The first part of this article reviews the behavior of CO2 in the presence of hydrocarbons and the leading action mechanisms in the recovery process. The second part examines the leading pilot or industrial applications and the operational problems

    Full Text Available L’alimentation intervient à différents niveaux dans le déroulement de la maladie cancéreuse : au niveau du risque [1] et au niveau de l’évolution en modifiant le risque de survenue des métastases. L’alimentation influence-t-elle aussi la réponse aux traitements anticancéreux ? À l’appui de cette hypothèse viennent deux observations indirectes réalisées dans le cancer du sein : nos données [2, 3] ainsi que les observations épidémiologiques provenant d’autres travaux [4] ont apporté des arguments supportant l’hypothèse que les lipides alimentaires peuvent influencer la réponse des tumeurs mammaires aux traitements. On sait que la composition des lipides membranaires n’est pas génétiquement déterminée, mais qu’elle dépend des acides gras disponibles aux tissus périphériques. Le type d’acides gras disponibles est influencé par les apports alimentaires. Comme les tumeurs incorporent dans leurs lipides les acides gras disponibles de façon similaire aux autres tissus [5], il est plausible que les habitudes alimentaires (apports alimentaires en acides gras polyinsaturés, vitamines anti ou pro-oxydantes puissent influencer leur chimiosensibilité en apportant aux cellules tumorales des substrats de peroxydation.

  3. Requirements Modeling with the Aspect-oriented User Requirements Notation (AoURN): A Case Study

    Science.gov (United States)

    Mussbacher, Gunter; Amyot, Daniel; Araújo, João; Moreira, Ana

    The User Requirements Notation (URN) is a recent ITU-T standard that supports requirements engineering activities. The Aspect-oriented URN (AoURN) adds aspect-oriented concepts to URN, creating a unified framework that allows for scenario-based, goal-oriented, and aspect-oriented modeling. AoURN is applied to the car crash crisis management system (CCCMS), modeling its functional and non-functional requirements (NFRs). AoURN generally models all use cases, NFRs, and stakeholders as individual concerns and provides general guidelines for concern identification. AoURN handles interactions between concerns, capturing their dependencies and conflicts as well as the resolutions. We present a qualitative comparison of aspect-oriented techniques for scenario-based and goal-oriented requirements engineering. An evaluation carried out based on the metrics adapted from literature and a task-based evaluation suggest that AoURN models are more scalable than URN models and exhibit better modularity, reusability, and maintainability.

    Full Text Available CASCADE is a decisional support system for shoe depth selection and casing design in exploration and production wells. This expert system is part of the ADIS project (Advanced Drilling Information System, jointly developed by three ENI companies : AGIP, ENIDATA, SAIPEM. The purpose of ADIS is to provide drilling engineering software tools for well planning and drilling operations support both at the office and rig site, to monitor real time operations and to diagnose drilling problems. To support real-time operations, ADIS project team developed tools for satellite communication between rigs and districts or headquarters, and expert systems to monitor operations, such as the status analyzer, on-line pressure gradients forecasts, alarms monitoring and management. The communication between different applications is provided by databases, both for the real time and the off line parts. The real time database is volatile; measurements are recorded on micrologs, which are in due time stored in the permanent, off line relational database for future use. Therefore, ADIS will provide better operations support and improved accuracy in well planning, with the ultimate aim of reducing risks and costs. CASCADE is part of the well planning tools developed for ADIS project: other software tools are related to directional well planning, hydraulics modelling, temperature prediction and gradients forecast. Casing shoe depth selection, and the consequent determination of geometrical and mechanical characteristics of casings, is a crucial activity. It heavily influences well planning and affects both safety and economical aspects of drilling operations. Accurate well and casing design can significantly reduce drilling costs and risks. Currently, casing design is carried out according to several requirements : company standards, common practice procedures, drilling engineers' experience and local regulations. Therefore, the choice of the best casing parameters which

    The aim of this paper is to provide information whether it is possible to consider the sustainable development perspectives in the decision making of the district energy decision. The new EU-directives concerning public procurements allow the use of environmental aspects as selection criteria. The focus here is on small-scale district heating systems and their fuel-supply chains. The comparable fuels included the analysis are forest chips, heavy fuel oil, light fuel oil and peat. The paper focuses to the concept of the sustainable development and establishes the indicators for ecological-, social- and economical aspects of the district heating. The indicators are utilized in the case study on the Eno Energy Cooperative. The equivalent CO{sub 2} emissions from the production and the combustion of the fuel, the employment impacts of the fuel production and the formation of the price of energy for the consumers are considered. After presenting the sustainable development indicators in the case of Eno Energy Cooperative, the investment models of heat entrepreneurship business are discussed. Finally, we also raise an attention into important aspects to be considered when establishing a local district heating scheme. The indicators used in this presentation show that the use of forest chips in energy production has positive effect through the reduced greenhouse gases. The use of wood in energy production also provides employment opportunities and is more favourable to consumers, because of the steady fuel price when compared to other alternative fuels.

    An examination has been carried out of non-alloyed uranium samples, having various structural states, cold-worked and recrystallized, as-cast and {beta}-treated, and irradiated at temperatures of between 450 and 600 C and with burn-ups from 1300 to 5500 MW days/metric ton. These samples swelled because of precipitation of the fission gases the porosity thus produced has a morphology depending mainly on the type of deformation to which the metal has been subjected and which is due to in-pile growth. The most homogeneous distribution of pores, and thus that leading to the minimum swelling, is only observed in the material having a marked [010] texture in which the growth and perhaps the thermal cycling introduce little or no strain. For other materials the deformation /swelling association causes a more rapid destruction of the samples either by cracking when the deformation is due to twinning, or by pronounced swelling localized in the bands when deformation is due to slipping. Finally the fission-gas precipitation considerably facilitates, above 500 C, the germination and growth of the intergranular cracks which can then develop at low stresses. (author) [French] On a examine des echantillons d'uranium non allie, de divers etats structuraux, marteles et recristallises, bruts de coulee et traites {beta}, irradies a des temperatures comprises entre 450 et 600 C, et a des taux de combustion allant de 1300 a 5500 MWj/t. Ces echantillons ont gonfle par suite de la precipitation de gaz de fission: la porosite ainsi fournie a une morphologie qui depend principalement des modes de deformation subie par le metal et due a la croissance en pile. La repartition la plus homogene des pores, donc celle qui donnera le gonflement minimum, est observee seulement dans le materiau a forte texture [010] dans lequel la croissance et eventuellement le cyclage thermique introduisent peu ou pas de contraintes.

    Full Text Available Au cours de cette dernière décennie, les études sur la consommation d’acides gras trans (AGT se sont multipliées pour en préciser l’impact éventuel sur le risque de maladies cardio-vasculaires (MCV. À l’origine, se trouve l’étude américaine de Willett et al. [1], conduite sur une cohorte de 85 000 infirmières suivies pendant 8 ans. Cette étude épidémiologique rapportait l’existence d’une corrélation positive entre la consommation d’AGT d’origine végétale et l’apparition de MCV. Ont suivi d’autres études que l’on peut classer en trois catégories selon leur approche expérimentale : les études épidémiologiques [2-5] longitudinales ou transversales, les comparaisons « cas-témoins » [6-11] et les interventions nutritionnelles [12-15]. Des deux premières catégories d’études, il n’émerge aucun consensus quant à l’implication éventuelle des AGT alimentaires dans le risque de MCV. Les divergences observées pourraient, en partie tout au moins, être liées à la méthode utilisée pour estimer la consommation d’AGT qui, dans certains cas, est fondée sur des enquêtes alimentaires et, dans d’autres cas, sur la teneur en AGT du tissu adipeux des sujets, connue pour refléter l’apport alimentaire en AGT des années précédentes. En effet, au-delà de considérations sur de possibles biais méthodologiques [16], comme le non-ajustement des résultats à des facteurs de confusion tels que l’âge, la consommation de tabac ou certaines pathologies, on peut faire le constat suivant : les études qui ont conclu à un effet négatif des AGT alimentaires étaient fondées, pour la plupart, exclusivement sur des enquêtes alimentaires [1-3, 11] ; celles qui ne montraient aucun effet utilisaient, le plus souvent, la composition en AGT du tissu adipeux [4, 6-9]. La carence, dans les bases de données, vis-à-vis des teneurs en AGT des aliments augmente, en outre, la difficulté à déterminer la

    Full Text Available This study has as its objective to analyze the critical aspects of the innovation management in terms of structure, strategy and processes of innovation of the Natura and Oxiteno companies. In order to do so, the study reviewed the literature about innovation management, strategies and processes of innovation. A multiple case study was adopted for the Natura and Oxiteno cases. As their data, instrument documents were obtained and interviews were made with managers and researchers working with innovation in both companies. A qualitative approach for the proposed problem was also utilized. The result highlighted similarities and differences within the structures and strategies of how innovation is developed inside and outside each company and their own innovation processes. In the case of Natura, the innovation funnel and technology funnel were used, whereas, in the case of Oxiteno, the innovation funnel and technology silos. Natura was distinguished for their model of open innovation, within the network, and for its sustainability culture. On the other hand, Oxiteno stood out for the freedom it gave to researchers to propose innovation projects. The study presented contributions to the organizations and academia by indicating some limitations in their development processes, as well as suggestions for further studies.

    This study aims to review the magnetic resonance imaging (MRI) aspects of a large series of patients with focal cortical dysplasia type II (FCD II) and attempt to identify distinctive features in the two histopathological subtypes IIa and IIb. We retrospectively reviewed the MRI scans of 118 patients with histological proven FCD IIa (n = 37) or IIb (n = 81) who were surgically treated for intractable epilepsy. MRI was abnormal in 93 patients (79 %) and unremarkable in 25 (21 %). A dysplastic lesion was identified in 90 cases (97 %) and classified as FCD II in 83 and FCD non-II in seven cases. In three cases, the MRI diagnosis was other than FCD. There was a significant association between the presence of cortical thickening (p = 0.002) and the ''transmantle sign'' (p < 0.001) and a correct MRI diagnosis of FCD II. MRI positivity was more frequent in the patients with FCD IIb than in those with FCD IIa (91 % vs. 51 %), and the detection rate of FCD II was also better in the patients with type IIb (88 % vs. 32 %). The transmantle sign was significantly more frequent in the IIb subgroup (p = 0.003). The rates of abnormal MRI results and correct MRI diagnoses of FCD II were significantly higher in the IIb subgroup. Although other MRI stigmata may contribute to the diagnosis, the only significant correlation was between the transmantle sign and FCD IIb. (orig.)

    Full Text Available In order to decouple economic growth from global material consumption it is necessary to implement material efficiency strategies at the level of single enterprises and their supply chains, and to implement circular economy aspects. Manufacturing firms face multiple implementation challenges like cost limitations, competition, innovation and stakeholder pressure, and supplier and customer relationships, among others. Taking as an example a case of a medium-sized manufacturing company, opportunities to realise material efficiency improvements within the company borders—on the supply chain and by using circular economy measures—are assessed. Deterministic calculations and simulations, performed for the supply chain of this company, show that measures to increase material efficiency in the supply chain are important. However, they need to be complemented by efforts to return waste and used products to the economic cycle, which requires rethinking the traditional linear economic system.

    Various problems of radioprotection concerning swimming-pool reactors in Grenoble have led us to study adequate solutions: a) The automatic verification of the staff-radioactivity when coming out of Melusine or Siloe has been realized thanks to a {beta}{gamma} gate which is insensitive to the ambient background in the reactor-hall; b) The automatic verification of the contamination of the shoes of the agents working in these reactors has been realized with a dedicated device; c) The necessity to measure precisely {gamma} doses with the help of an autonomous apparatus has led to the making of a plastic-scintillator {gamma} dosimeter; d) The obligation to forbid the opening of doors in some places where there might be a great intensity of radiation, has led us to make doors open according to the intensity of radiation inside the rooms; e) The releases of radioactive iodine have been measured with activated charcoal cartridges that surround a scintillator connected with a unique channel selector; f) Finally the control of reactor safety rod fall in case of a radioactive accident has been secured by a chain whose detector is a chamber immersed in the swimming-pool, which offers, in the particular case of the hot thickness swimming-pool reactor a double advantage: first it enables us to regulate the upper hot water layer, second to get free of transitory radiations which appear in the reactor hall as the experimental apparatuses are taken out from the core.

    An understanding of the functional aspects of gait and balance has wide ramifications. Individuals with balance disorders often restrict physical activity, travel, and social commitments to avoid falling, and loss of balance confidence, itself, is a source of disability. We studied the functional aspects of gait in patients with essential tremor (ET), placing their findings within the context of two other neurological disorders (Parkinson's disease [PD] and dystonia) and comparing them with age-matched controls. We administered the six-item Activities of Balance Confidence (ABC-6) Scale and collected data on number of falls and near-falls, and use of walking aids in 422 participants (126 ET, 77 PD, 46 dystonia, 173 controls). Balance confidence was lowest in PD, intermediate in ET, and relatively preserved in dystonia compared with controls. This ordering reoccurred for each of the six ABC-6 items. The number of near-falls and falls followed a similar ordering. Use of canes, walkers, and wheelchairs was elevated in ET and even greater in PD. Several measures of balance confidence (ABC-6 items 1, 4, 5, and 6) were lower in torticollis cases than in those with blepharospasm, although the two groups did not differ with respect to falls or use of walking aids. Lower balance confidence, increased falls, and greater need for walking aids are variably features of a range of movement disorder patients compared to age-matched controls. While most marked among PD patients, these issues affected ET patients as well and, to a small degree, some patients with dystonia.

  19. Methodology of intervention during a mystery spill: The example of the Baie-des-Sables case

    A mystery spill, or an oil spill of unknown origin, is one whose source cannot be identified at the time the environmental impact of the spill is noted. Unlike a known incident during which preventive action may be taken, mystery spills are often assessed based on the damages they have caused. In Canada, the coast guard regularly reports many spills with unidentified sources, and the most frequently reported sign of a spill is the presence of an oily film on the water surface. The smell of oil is also an important indication of a recent spill. The spill at Baie-des-Sables, Quebec, is presented as an illustrative example of a mystery spill. The size of the spill was estimated at 25 tons of bunker oil. The first indication of the spill was a number of contaminated ducks from the Rimouski region, reported by hunters to the appropriate government agency. Two days later, an oil slick was reported in the channel between Baie-Comeau and Rimouski; this provided sufficient information to trigger an alert. The next day an aerial inspection of the slick was carried out and a dispersion model was made. Contamination of seagulls and the south shore of the St. Lawrence River were noted. Over the next week response measures were organized and more inspections of shorelines were undertaken. Of the shoreline studied, 50 km were contaminated and 14 km were restored. Lack of precise early observations of the slick precluded identification of the vessel responsible for the spill. Recommendations are made for improving assessment of mystery spills and ensuring faster response times. 1 fig

    Full Text Available Objective: To assess the prevalence of congenital defects and to investigate their maternal and perinatal associated aspects by reviewing Birth Certificates. Methods: Among all born alive infants from January 2003 to December 2007 in Maternidade da Santa Casa de Misericórdia of São Carlos, Southeast Brazil (12,199 infants, cases were identified as the newborns whose Birth Certificates registered any congenital defect. The same sex neonate born immediately after the case was chosen as a control. In total, 13 variables were analyzed: six were maternal related, three represented labor and delivery conditions and four were linked to fetal status. The chi-square and Fisher's exact tests were used to compare the variables, being significant p<0.05. Results: The prevalence of congenital defects was 0.38% and the association of two or more defects represented 32% of all cases. The number of mothers whose education level was equal or less than eight years was significantly higher among the group with birth defects (p=0.047. A higher frequency of prematurity (p<0.001 and cesarean delivery (p=0.004 was observed among children with birth defects. This group also showed lower birth weight and Apgar scores in the 1st and the 5th minute (p<0.001. Conclusions: The prevalence of congenital defect of 0.38% is possibly due to underreporting. The defects notified in the Birth Certificates were only the most visible ones, regardless of their severity. There is a need of adequate epidemiological monitoring of birth defects in order to create and expand prevention and treatment programs.

    Full text of publication follows: Background: Malignant melanoma corresponds to 5% of cutaneous neoplasias. However, umbilical melanoma is a rare occurrence, with only 13 cases reported on the literature. The purpose of this article is to present a case of umbilical primary melanoma, discuss the anatomy and lymphatic drainage of this region, and the therapeutic aspects. Clinical description: Three years ago, a 65 years-old white woman from Recife-PE, presented an umbilical pigmented nevus. It grew in size and one year ago the pigmentation increased. Examination showed depressed umbilical scarring completely filled by pigmented lesion with 1.5 cm, irregular borders and a depigmented area; no enlarged inguinal and axillary lymph nodes. Chest X-Ray, CT scan of abdomen and pelvis, and ultrasonography of groin and axillary lymphatic chains were normal. The pathological diagnosis after incisional biopsy was ulcerated malignant melanoma, without defining Breslow classification. Subsequently a complete excision of the lesion was performed; slide showed Breslow 8 mm and 1 mm of margin. Lymphoscintillography showed three left axillary lymph nodes. During surgical widening, the peritoneum seemed disease-free. Lymphatic mapping identified three lymph nodes, one of them not coloured by vital blue. All the lymph nodes were free of metastasis on histopathological and immunohistochemical examination. Discussion: Among the umbilical tumors, 80% are metastatic, the most common branch of which is the gastrointestinal tract. Melanoma is included in the other 20% corresponding to primary neoplasias of the umbilicus, which also include sarcomas, basal cell carcinomas and squamous cell carcinomas. From the embryological point of view, the umbilical scar can contain residues of several types of epithelial tissue of the gastrointestinal duct remaining from the omphalomesenteric duct. Anatomical aspects remain to be studied, such as the cylindrical form and the content within its thickness

    Full Text Available Microbial aspects of endo-β-1,4-xylanase production in solid-state fermentation by Penicillia: the case of Penicillium canescens. Production of xylanases by Penicillium canescens 10-10c is the research object in Walloon Center of Industrial Biology. Previous works used submerged or liquid fermentation. The actual works are oriented more and more towards solid fermentation from agricultural or agro-alimentary residues. In addition to the valorization of these residues, solid-state fermentation reaches an increasingly significant interest in various other fields like the biological breakdown of the solid residues, the bioremediation of the organic pollutants in the grounds and the reduction of the air pollution by the biofiltration. Xylanase is an industrial enzyme used in general in extraction and clarification processes. P. canescens can produce an activity of it, particularly in its balanced forms of xylanases, beta-xylosidase and arabinosidase, and not contaminated by cellulolytic and amylolytic activities. It is a hyper producing strain of xylanase. The production rate is one of the highest in literature (535 U.ml-1 and 9,632 U.g-1 in Erlenmeyer flasks, in submerged and solid state fermentation, respectively. The biobleaching activity of the cellulose pulp by the purified enzyme is higher than a commercial preparation of xylanases from Trichoderma longibrachiatum used industrially. It has a complete hydrolysis degree of 40% (on glucuronoxylan and 35% (on arabinoxylan at 55°C and at pH of 5.9. These characteristics lead to many industrial applications of this enzyme. That is why the optimization of its production by the solid-state fermentation at the laboratory scale in order to define a policy for the industrial transposition later is carried out. This article presents a summary of the scientific literature on this subject.

    Full Text Available Mineral-alkali interactions have received considerable attention in the recent literature dealing with enhanced oil recovery techniques and clay stabilization treatments. One of the critical factors to be considered is alkali consumption. Alkalinity decrease occurs through several mechanisms, which are ion exchange, precipitation, reaction with crude oil components, and dissolution of minerals. This paper describes the dissolution process. An original kinetic model is proposed to describe the alkaline dissolution of a clayey sandstone. This model is based first on results concerning quartz dissolution/condensation processes. It is also based on new experimental data, which demonstrate the inhibiting effect of aluminum and, as the reaction proceeds, the precipitation of an aluminosilicate whose the chemical composition has been determined. From these data, a kinetic scheme has been conceived in which adsorption of different chemical species is assumed to occur onto solid surfaces. These species play a more or less important role according to the extent of the reaction. In the mechanisms considered, the argillaceous fraction of the rock provides silicon and aluminum which inhibit the dissolution of the matrix while silicon coming from quartz interferes with clay attack. The kinetic model depicts the coupling of elementary dissolution processes and calculates dissolved silicon and aluminum. It has been tested for various operating conditions, providing initial reaction rates for quartz and clay. Results emphasize the definitive advantage of carbonate compared to other alkaline chemicals owing to the relative low pH of solutions, which is particularly favorable for promoting inhibition by aluminum and, as a general rule, for reducing mineral dissolution.

    Full Text Available The pupil-teacher communication and the teacher communication skills seem to be key concepts to reach the objectives of the educational act. Recent studies highlight the link between the teacher communication skills, their efficiency, and the fact that these skills could play a more important role for the education that the teaching staff training, his intelligence level and teaching methods. The research goal was the investigation of the aspects specific to the educational communication, that constitute facilitator factors and barriers in the learning process and in the relation teacher-pupil. The quantitative analysis was based on a questionnaire for pupils and teachers, that aimed the investigation of the respondents perception on what it is a good teacher in order to identify those skills that make the difference, from the pupils point of view, and also from the teachers point of view, between a competent teacher and an ineffective one. The research used a double approach, quantitative and qualitative one. The quantitative study allowed the inclusion of a number of 151 subjects and the survey of some dimensions of teacherpupil communication. The qualitative research used a number of 47 subjects, but it allowed the consolidation of the approached topics. The results obtained were interpreted based on the differences that appear in the pupils and teaching staff opinions, but also through the investigation of those dimensions that make the difference, in the case of a model teaching staff, between the pupils and teachers perceptions.

    Full Text Available L'erreur sur l'évaluation des réserves en place d'un gisement d'hydrocarbures dépend de trois facteurs : - erreur aux puits sur la détermination des porosités et saturations; - erreur géostatistique d'extension au gisement des mesures effectuées aux puits ; - erreur géométrique d'évaluation de la surface ou du volume du gisement. Dans ce texte nous avons étudié l'influence du nombre et de la distribution des puits sur l'erreur géostatistique dans le cas d'un gisement fictif de forme elliptique. Nous nous sommes placés à différents niveaux de reconnaissance, depuis l'implantation d'un seul puits en position variable jusqu'à la couverture complète du gisement par une grille régulière de 48 puits... La méthode utilisée est le « krigeage » élaboré par G. MATHERON de l'École des Mines de Paris. Les calculs ont été réalisés à l'aide du programme KRIGEPACK développé par une association CFP-SNPA. L'erreur d'estimation dépend de la position des puits dans le gisement, de la plus ou moins grande continuité spatiale de la variable et des erreurs aux puits. L'erreur que l'on peut calculer par la statistique classique ne dépend que du nombre de puits et suivant le cas peut être trop importante (si les puits sont implantés de manière optimale ou au contraire trop faible (si les puits sont mal disposés. The error in evaluating reserves in place in a hydrocarbon reservoir depends on The following three factors I - an erorr in wells when determining porosities and saturations ; 2 - a geosfatistical error in extending well measurements ta the entire reservoir; 3 - a geometric error in evaluating the area or volume of the reservoir. This article studies the influence of well number and distribution on the geostatistical error in the case of an elliptically-shaped imaginary reservoir. Various levels of exploration are considered, from the existence of a single well in various positions to full coverage of the reservoir by a

    Although enormous progress has been made in recent years in the field of haemophilia, some problems still await solution, such as the risk of sudden haemorrhage, the sequelae of haemophilic arthropathy and social activities. We, therefore, carried out a case-control study in which some psychological dimensions (social expectations, tendency to depression, state of anxiety and self-esteem) were evaluated in a group of 60 haemophiliacs. A control group was formed of 78 healthy subjects matched for age, socio-economic class and level of education. The methodology used was the administration of self-assessment questionnaires which investigate and provide a quantitative measure of psychological dimensions. The results can be subjected to statistical analysis. Three self-assessment questionnaires were used: (i) the Marlowe-Crowne scale, (ii) the Beck Inventory version modified by Cusinato and (iii) the S.T.A.I.-form. Our aim was to evaluate: (i) whether there are significant differences in the considered psychological aspects between haemophiliacs and healthy subjects; (ii) whether there is a significant correlation between the psychological dimensions considered in the haemophiliacs and in the healthy subjects. The results showed that the haemophiliacs have a good psychological adaptation to their disease with the exception of their greater tendency to have less self-esteem than do the healthy subjects. As far as concerns the second aim, we found than self-esteem correlated with all the psychological variables investigated. This information could indicate the enormous importance that the psychological variable 'self-esteem' plays in haemophiliacs with respect to whether or not they develop depressive disorders and/or anxiety states.

    Full Text Available Regional and local geological constraints for location of natural stone deposits in glaciated terrains of southern and central Finland have been studied and applied to practical exploration for natural stone. A list of geological and topographical aspects to be considered in exploration, is presented. Important aspects refer to: 1. Regional geology of the target area. 2. Magmatism (type and structure of intrusion, relative time of pluton emplacement. 3. Metamorphism (grade, mineral composition, parent material. 4. Deformation (lineaments, shear zones, folding, fault zones, fracture zones, shape preferred mineral orientations, and 5. Topography (relative elevation, micro topography. The proposed aspects can be used as geological guidelines in exploration for granitic natural stones.

    The platinoids deposits, currently in exploitation, are often associated with dunitic and gabbroitic ultra-basic rocks containing copper, nickel and iron sulfides. The proportion of platinoids in these deposits is variable and requires generally an adaptation of the industrial processes for their recovery. Nevertheless, we can consider that the classical industrial way consists to treat the composite concentrates of copper-nickel-platinoids sulfides by melting/conversion operations following by hydrometallurgical operations of recovery of the basic metals Cu, Ni. These last ones concentrate the platinoids in leaching residues. In these residues, the platinoids are extracted and separated by hydrometallurgical ways including different techniques: dissolution, selective precipitation, distillation, solvent extraction, resins...The great variety of uses of platinoids makes their recycling difficult. The wastes are often too complex for being economically recycling. The environmental protection depends of the type of industry (metallurgical, chemical, mining). Some products present risks of fire and explosion. The toxicity often appears by superficial allergies and by serious troubles in case of ingestion of soluble salts. (O.M.)

    The dispersal of trace substance in groundwater may be limited by dissolution and precipitation and, of particular interest in this paper, by sorption and desorption processes. These surface-active processes, which have a decisive influence on groundwater quality, depend on the concomitant geochemical conditions prevailing in the water, the constituents of the aquifer and on the surface properties of the solids. Taking the geochemical conditions prevailing naturally in brown coal mining areas as a point of departure this study was aimed at examining the influence of acidification processes on the transport behaviour inorganic pollutants for the example of zinc. For this purpose oxic column trials were carried out on sandy aquifer material. The data were supplemented by a detailed characterisation of the solid surfaces and modelled on the basis of a transport-reaction model as well as mechanistically with due regard to surface complexing. [German] Die Ausbreitung von Spurenstoffen im Grundwasser wird ausser durch Loesungs- und Faellungsprozesse vor allem durch Sorptions- bzw. Desorptionsvorgaenge limitiert. Diese fuer die Grundwasserqualitaet entscheidenden oberflaechenaktiven Prozesse sind von den variablen geochemischen Randbedingungen im Wasser, vom Stoffbestand des Aquifers und von den Oberflaecheneigenschaften der Feststoffe abhaengig. In Anlehnung an die natuerlichen im Bereich von Braunkohle-Abbaugebieten herrschenden geochemischen Bedingungen wurde der Einfluss von Versauerungsprozessen auf das Transportverhalten von anorganischen Schadstoffen, am Beispiel von Zink, auf der Basis von oxischen Saeulenversuchen an sandigem Aquifermaterial untersucht. Die Daten wurden durch eine detaillierte Charakterisierung der Feststoff-Oberflaechen ergaenzt und sowohl mit Hilfe eines Transport-Reaktionsmodells als auch mechanistisch unter Einbeziehung der Oberflaechenkomplexierung modelliert.

    Décrit la première fois par Virchow en 1860, le liposarcome est une tumeur mésenchymateuse rare. Cette rareté est relative car les liposarcomes représentent quand même 14 à 18% de l'ensemble des tumeurs malignes des parties molles et ils constituent le plus fréquent des sarcomes des parties molles. Pour la majorité des auteurs, il ne se développerait jamais sur un lipome ou une lipomatose préexistant. Nous rapportons un cas de volumineux liposarcome de la face dorsale du tronc. L'histoire de la maladie, l'aspect clinique inhabituel « de tumeur dans tumeur », l'aspect de la pièce opératoire nous fait évoquer la possibilité de la transformation maligne d'un lipome bénin préexistant.

    Shared psychotic disorder (folie à deux) is a rare condition characterized by the transmission of delusional aspects from a patient (the "dominant partner") to another (the "submissive partner") linked to the first by a close relationship. We report the case of two Moroccan sisters who have experienced a combined delusional episode diagnosed as shared psychotic disorder. In these circumstances, assessment of symptoms from a cross-cultural perspective is a key factor for proper diagnostic evaluation.

    Vasculitis is a rare disease and clinical symptoms are often unspecific. Accurate and early diagnosis is mandatory in order to prevent complications, such as loss of vision or stroke. Imaging techniques can contribute to establishing a definite diagnosis and to evaluate disease activity and the extent of the disease in various vascular regions. Conventional imaging methods, such as computed tomography (CT) and magnetic resonance (MR) angiography, as well as digital subtraction angiography allow the vessel lumen but not the vessel wall to be depicted. However, vasculitis is a disease which primarily affects the vessel wall, therefore conventional imaging modalities often fail to make a definite diagnosis. Recently black-blood high resolution MR in vivo imaging has been used to visualize cervical and intracranial vasculitis. This review article presents imaging protocols for intracranial and cervical black-blood MR imaging and clinical cases with large vessel vasculitis and vasculitis of the central nervous system. Furthermore the current literature, examples of the most common differential diagnoses of cervical and cranial arteriopathy and the potential of other imaging modalities, such as PET/CT and ultrasound will be discussed.

    Full Text Available The cross-border area between Albania and Macedonia can be considered as a region with agrarian or industrial-agrarian economy, although the overall picture should take into account significant contrasts within the region, between the two countries, but also between the southern and northern part, and between mountainous areas and lowlands. Agriculture, agribusiness, light industry, mining, energy production and tourism are the main economic sectors, which also have the biggest potential in the cross-border region. Both countries are gaining experience in EU funded cross-border cooperation programmes with other neighbouring countries and with each other. The scope of the research is the evaluation and analysis of the Integrated Pre-accession Assistance (IPA Cross-border Cooperation (CBC Programme Macedonia-Albania 2007-2013 and its sustainable development aspects. The research is trying to assess the impact of the programme since its start in 2007 and the impact of the implemented grants on the sustainable development. The importance of the sustainable development aspect is recognized and is formally included into various national strategic documents, however implementation is often problematic and sustainability aspects need to be examined on a more concrete level. The methodology used was qualitative with research tools such as desk studies of relevant program documentation, strategic and planning documentation and other relevant published materials. The desk review considered well over 40 documents relevant to the program, most of which were shared by the Ministry of European Integration (MoEI and other actors.

    Anticipating case management is considered crucial in pediatric palliative care. In 2012, our children's university hospital initiated a specialized pediatric palliative care team (PPCT) to deliver inbound and outbound case management for children with life-shortening disease. The aim of this report is to gain insight in the first 9 months of this PPCT. Aspects of care during the first 9 months of the PPCT are presented, and comparison is made between patients with malignant disease (MD) and nonmalignant disease (NMD) in a retrospective study design. Insight in the aspects of care of all patients with a life-shortening disease was retrieved from web-based files and the hour registrations from the PPCT. Forty-three children were supported by the PPCT during the first 9 months: 22 with MD with a median of 50 (1-267) days and 29 minutes (4-615) of case management per patient per day and 21 patients with NMD with a median of 79.5 (5-211) days and 16 minutes of case management per day (6-64). Our data show significantly more interprofessional contacts for patients with MD and more in-hospital contacts for patients with NMD. The median number of admission days per patient was 11 (0-22) for MD (44% for anticancer therapy) and 44 (0-303) for NMD (36% for infectious diseases). This overview of aspects of pediatric palliative case management shows shorter but more intensive case management for MD in comparison with NMD. This insight in palliative case management guides the design of a PPCT.

    The statement is not new, but is repeatedly a tropical subject. Further technological developments permit advances, e.g. in medicine, production, communication or energy supply. This is particularly clear from the example of natural gas. As with other fossil energy sources the resources are also limited in this case, which is all the more painful, because natural gas is an ideal product in the creation of the energy revolution. In this situation it is highly appropriate that with a special method it is possible to exploit deposits, which could not be developed economically until a few decades ago. (orig.)

    Brucellosis is an ubiquitous anthropozoonoses in the Republic of Djibouti, but it has only been studied in the City of Djibouti. This retrospective study of 42 cases of human brucellosis diagnosed between April 1993 and April 1995 was carried out at the Peltier Hospital in Djibouti to obtain epidemiological data concerning brucellosis in the Republic of Djibouti. Diagnosis was based on clinical symptoms and positive immunologic tests (Rose Bengal test > 100 UI and Wright serology > 1/80). The following information was obtained for each patient: nationality, ethnic origin, place of residence, age, sex, and risk factors for exposure to infected animals or products. There were 30 men and 12 women including 38 Djiboutis, 3 Somalis, and 1 Ethiopian. Ethnic origin was Afar in 32 cases, Somali in 6 cases, and undetermined in 4 cases. Mean age was 31.6 years. Of the 38 Djiboutis, 15 lived in the district of Djibouti, 17 in the district of Tadjourah, 3 in the district of Obock, and none in districts located in the Southern part of the country. In 18 cases brucellosis involved cattle raisers from the Northern part of the country. In five cases no risk factor could be identified. The incidence of brucellosis in the Republic of Djibouti appears to be comparable to that observed in other highly endemic countries. Further study is needed to determine the exact incidence in man and animals and ascertain the need and feasibility of preventive measures.

    The scope of this study covers safeguards licensing aspects of a possible future Gen IV demonstration facility. As a basis for the investigation, the facility was assumed to be located in Sweden, comprising a lead-cooled fast reactor and a reprocessing plant with fuel fabrication. The aim has been to identify safeguards requirements that may be set by the IAEA and the Swedish Radiation Safety Authority, and also to suggest how the safeguards system could be implemented in practice. The changed usage and handling of nuclear fuel, as compared to that of today, has been examined in order to determine how today's safeguards measures can be modified and extended to meet the needs of the demonstration facility. This work is part of GENIUS, the Swedish Gen IV research and development programme, which emphasizes lead-cooled fast reactors. (author)

  15. FUNDAMENTAL ASPECTS OF COMMUNICATION MANAGEMENT, IN THE CASE OF PUBLIC ADMINISTRATION

    Full Text Available Efficient communication is one the most important instruments used for the purpose of generating change inside and outside an organization. It can contribute to adjusting attitudes and the manner of approaching the present and future challenges and to changing behavioral patterns. The mission and the objectives of organizational communication are highly interrelated with organizational change and environment characteristics, in which the organization functions. The communication performed by the public administration institution outside is an institutional communication, extra-organizational, which presents the following purposes: strengthening its image, stimulating an environment of trust and affinity from the citizens (Kotler & Lee, 2007. We are of opinion that the management of communication performed by a public administration institution features three fundamental aspects, relevant for institutional communicators when designing and managing the institutional communication: communication efficiency, communication process and the implications of the new information and communication technologies (ICT for this process.

  16. Book swapping and book exchange libraries: Aspects of the phenomenon and the case of Greece

    Science.gov (United States)

    Bikos, Georgios; Papadimitriou, Panagiota

    2015-02-01

    We have over the past years been witnessing an ever growing book-swapping movement, having begun its course from the mere existence of bookshelves offering books to be traded in public places or via the internet and ending with small exchange and free to use libraries scattered in different areas. We believe that through this movement an answer is being uttered to the request for a better world and against the economic crisis, which is also a crisis of values. Based on this perspective, in this paper, we first attempt an overall presentation of the phenomenon and its characteristics, as they manifest themselves worldwide. Then, we focus on aspects of relevant attempts in Greece, taking their first tentative steps.

    Neu, Alexandre da Silva; Menezes, Roger Eliandro; Maciel, Antonio Carlos; Castro, Rogerio Fernandes Peixoto de

    2003-01-01

    Bronchial atresia is a rare congenital abnormality that usually shows a juxta-hilar mass with distal radiolucency on conventional x-ray films. Most patients are young and have no symptoms. Computed tomography usually confirms the diagnosis, allowing conservative management of the asymptomatic cases. The authors report three cases of bronchial obstruction. One of the patients was of particular importance and interest, a 45-year-old female patient with symptoms of respiratory infection, due to the association with a bulky bronchocele. The diagnosis was made by analyzing the findings of conventional x-ray films and computed tomography, and the comparison with previous conventional x-ray films and linear tomography, which had already demonstrated abnormalities. A literature review on the clinical and radiological findings of this pulmonary malformation is presented. (author)

    Full Text Available Abstract Delivering quality primary care to large populations is always challenging, and that is certainly the case in India. While the sheer magnitude of patients can create difficulties, not all challenges are about logistics. Sometimes patient health-seeking behaviour leads to delays in obtaining medical help for reasons that have more to do with culture, social practice and religious belief. When primary care is accessed via busy state-run outpatient departments there is often little time for the physician to investigate causes behind a patient's condition, and these factors can adversely affect patient outcomes. We consider the case of a woman with somatic symptoms seemingly triggered by psychological stresses associated with social norms and familial cultural expectations. These expectations conflict with her personal and professional aspirations, and although she eventually receives psychiatric help and her problems are addressed, initially, psycho-social factors underlying her condition posed a hurdle in terms of accessing appropriate medical care. While for many people culture, belief and social norms exert a stabilising, positive influence, in situations where someone's personal expectations differ significantly from accepted social norms, individual autonomy can be directly challenged, and in which case, something has to give. The result of such challenges can negatively impact on health and well-being, and for patients with immature defence mechanisms for dealing with inner conflict, such an experience can be damaging and ensuing somatic disturbances are often difficult to treat. Patients with culture-bound symptoms are not uncommon within primary care in India or in other Asian countries and communities. We argue that such cases need to be properly understood if satisfactory patient outcomes are to be achieved. While some causes are structural, having to do with how healthcare is accessed and delivered, others are about cultural

  2. Spatial and temporal aspects of grain accumulation costs for ethanol production: An Australian case study

    Anderton, Nikki; Kingwell, Ross

    2008-01-01

    Ethanol production is increasingly commonplace in many grain-producing regions. This paper uses the grain-producing region of south-western Australia to illustrate spatial and temporal aspects of grain accumulation costs for ethanol production. Specifically, this study examines how price variability of various wheat grades, combined with spatial and temporal variability in production of those grades, affects the costs of grain accumulation. These costs are the main components of an ethanol plant's operating costs so lessening these costs can offer a comparative advantage for a plant owner. Logistics models based on mathematical programming are constructed for a range of plant sizes and locations for ethanol production. Modelling results identify low-cost sites that generate cost savings, in present value terms, of between 5 and 7.5 per cent, depending on plant size, over the 9-year study period. At all locations, small to medium-sized plants offer advantages of lower and less variable costs of grain accumulation. Yet, all locations and all plant sizes are characterised by marked volatility in the cost of grain accumulation. The profitability of ethanol production based on wheat in this region of Australia is particularly exposed to any prolonged period of high grain prices relative to petroleum prices, given current biofuel-policy settings in Australia.

    Despite the growing rates of obesity and diet-related non-communicable diseases, globally, public health attention has only relatively recently turned to the links between trade agreements and the nutritional risks associated with it. Specific trade agreements appear to have played an influential role in the volume and types of foods entering different countries, yet there is currently no systematic and objective monitoring of trade agreements for their impacts on food environments. Recently, INFORMAS was set up to monitor and benchmark food environments, government policies and private sector actions within countries and globally. One of its projects/modules focuses on trade policy and in particular the food-related aspects of trade agreements. This paper describes the INFORMAS trade protocol, an approach to collecting food-related information about four domains of trade: trade in goods; trade in services and foreign direct investment; domestic supports, and policy space. Specifically, the protocol is tested in Fiji. The development and testing of this protocol in Fiji represents the first effort to set out a framework and process for objectively monitoring trade agreements and their impacts on national food supply and the wider food environment. It has shown that entry into WTO trade agreements contributed to the nutrition transition in Fiji through the increased availability of imported foods with varying nutritional quality. We observed an increase in imports of both healthy and less healthy foods. The application of the monitoring protocol also highlights challenges for data collection associated with each trade domain that should be considered for future data collection and analysis in other low and middle income countries. © The Author 2017.

    The consumption of bottled water in Italy began in the 1970s. Since then, this usage has grown considerably, also as a result of changes in habits. The environmental impact as a result of the water production chain is very significant; it would be considered, for example, the use of plastic bottles, the consumption of oil in the production of the bottles, the emission of air from the vehicles that transport the bottles, non-recycled plastic packaging, etc. In this study, considering the comparison between two situations, use of bottled water and use of water kiosk (WK), an environmental and economic impact evaluation has been done. The study considered the production of a WK in a town with 9000 inhabitants, which supplies controlled, still and sparkling water, with an organoleptic quality higher than tap water coming from the aqueduct. In particular, taking into consideration the environmental aspects, specific attention was paid both to CO2 emissions and PET bottle waste reduction. The economic impact evaluation was carried out from the consumer's point of view. In order to provide a supply service that was economically sustainable, a calculation was done with the aim of determining a specific fee for the supplied water. Moreover, a comparison has been made between quality parameters achieved with the analysis of water from aqueducts with the limits established in the Italian legislation and the parameters of several Italian water brands. The study has the aim at considering the opportunity to follow a different people's habits, closer to the concept of sustainability, reducing the environmental charge related to the realization, transport and consumption of plastic water bottles without significant reduction of the quality of the service and with convenient and interesting economic implications. In fact the results of the study show that the alternative of WKs is more efficient in economic and environmental terms respect to the use of bottled water. Copyright

  6. Histopathological aspects of neutrophilic dermatoses: Investigation of 38 cases and review of the literature

    2016-01-01

    Full Text Available Introduction: Neutrophilic dermatosis (ND is a heterogeneous group of diseases with various etiologies and clinical presentations. NDs may clinically present as papule, vesiculopustule, plaque, and nodule of the skin, but they all share the common feature of neutrophilic predominance in the skin. Histological examination of patients with suspected ND is a key step for making the proper diagnosis. Patients and Methods: The aim of this article was to investigate histopathological aspects of different NDs. We obtained our data from medical records of patients at Razi dermatology hospital, between 2012 and 2014. Thirty-eight biopsy records coded under the term of any ND, including Sweet's syndrome (SS, pyoderma gangrenosum (PG, skin lesions of Behcet's disease, neutrophilic drug eruption, amicrobial pustulosis of the folds, pustular vasculitis of the hands, and undetermined ND were recruited in our study. The specimens were evaluated regarding inflammatory reaction pattern, epidermal/adnexal changes, and dermal changes. Results: Most common NDs in our study were PG (42.1% followed by SS (21.1%. The most common pattern of inflammatory reaction was superficial perivascular and interstitial dermal inflammation in 44.7% of the patients. Exocytosis of neutrophils into epidermis, hair follicle, and eccrine gland was seen in 71%, 18.5%, and 28.9% of the specimens, respectively. Ulceration was only seen in ten PG specimens. Dermal fibrosis and vascular proliferation were reported in all PG patients. Conclusion: The prevalence of some histopathological findings in different types of ND was significantly different. These features seem helpful in distinguishing between different NDs.

    1989-05-01

    Within the framework of a cooperative agreement between Sofratome and the Office National d'Electricite of Morocco, the Centre National de la Recherche of Rabat, with the collaboration of the French Institut de Protection et de Surete Nucleaire, was put in charge of compiling a revised catalogue of the historical seismicity of Morocco. The method adopted calls for the participation of several different disciplines in view of situating each earthquake in its own geographical and historical context. The approach entails, during the first stage involving primarily the historian, gathering together the original sources of data and subjecting them to a critical analysis in order to assess their reliability. The second stage consists in interpreting the information so as to define those earthquake characteristics that are requisite to seismic hazard studies. This latter evaluation must be the fruit of a multidisciplinary effort. This is particularly true for earthquakes of past centuries, the observations of which are frequently incompatible or biased and accordingly need to be substantiated by referring to information of a varying nature and, wherever possible, calibrated using accurate data from recent events. In a number of instances, duplications are encountered, or lumped effects for distinct events due to calendar misreckonings, erroneous copying, or misconceptions relative to the geological or historical context. A particularly significant example of the interference of these diverse aspects is afforded by the assessment of the destructive effects in Morocco of the 1755 'Lisbon' earthquake: a method is proposed for calibrating its intensities by comparing them with those of the recent 1969 event of similar origin

    2012-01-01

    Angiomyolipoma (AML) is a rare and usually benign mesenchymal tumor histologically composed of adipose tissue, smooth muscle cells and abnormal blood vessels. It occurs most commonly in the kidney, less frequently in another anatomical locations. In submitted work we retrospectively assessed the prevalence of renal AMLs in the set of patients with renal neoplasms and evaluated the basic clinico-pathological parameters of disease. The whole study group consisted of 223 primary kidney tumors, which had been histologically diagnosed between January 2009 − June 2012. In this 3.5- year period, we found 12 cases (5.3 %) of renal AML from 12 subjects (10 women, 2 men) in the age range from 35 to 65 years (average 48.1 years). Right (n = 5) and left (n = 6) kidney was affected almost equally and one man suffered from bilateral involvement. The size of lesions varied between 0.5 − 10 cm (average size 4.7 cm). Except two patients with multifocal angiomyolipoma manifestation, all the others were solitary. There were two cases of coincidence of AML with another tumor types in the same kidney. Microscopically, we found all basic structural components of AMLs in almost all lesions, however, their proportion differed significantly. Half of the cases corresponded to monophasic AML switch a marked predominance of only one histological component. Immunohistochemically, all cases were at least focally positive for Melan-Aand HMB-45 and smooth muscle component was diffusely positive for actin. In comparison with literature data, we revealed somewhat higher prevalence of renal AML. From the view of the biopsy practice there is important, the histomorphological components variations in the individual lesions, as well as the occurrence of some rare AML variants may mimic other tumor. Thus, it may cause a differential diagnosis more difficult. Because of a relatively common multifocality of AML, as well as coincidence with another neoplasms within the same kidney, it is necessary to

    Infantile infections are thought to constitute one of the main bases of the etiology of Swyer-James syndrome. This case seems to support the above theory allowing for the anamnesis of the pleuritis at 2 years of age, bronchographical findings - bilateral but markedly left-sided bud-like bronchiectatic changes - and left pulmonary angiographical findings - simultaneous appearance of pulmonary arteries and veins with scarce capillary image. Concerning the ventilation of this syndrome, /sup 133/Xe inhalation test showed a ''Pendelluft'' phenomenon, shift of /sup 133/Xe from the healthy to the affected lung on forced expiration.

    Full Text Available Among primary thyroid neoplasms, papillary thyroid carcinoma (PTC and primary thyroid lymphoma (PTL are known to coexist and are pathogenetically linked with Hashimoto′s thyroiditis (HT. However, HT occurring in association with medullary thyroid carcinoma (MTC is rarely documented. We report here an interesting case. A 34-year-old female with a solitary thyroid nodule underwent fine needle aspiration cytology (FNAC that was interpreted as "MTC with admixed reactive lymphoid cells, derived possibly from a pretracheal lymph node." Total thyroidectomy specimen showed "MTC with coexisting HT." At a later stage, a follow-up FNAC from the recurrent thyroid swelling showed features consistent with HT. As an academic exercise, the initial smears on which a diagnosis of MTC was offered were reviewed to look for evidence of coexisting HT that showed scanty and patchy aggregates of reactive lymphoid cells without Hόrthle cells. Our case highlights an unusual instance of MTC in concurrence with HT that can create a tricky situation for cytopathologists.

    From the early days of philosophy, ethics and justice, there is wide consensus that the constancy of the laws establishes the legal system. On the other hand, the rate at which we accumulate knowledge is gaining speed like never before. Due to the recently increased attention of academics to climate change and other environmental issues, a lot of new knowledge has been obtained about carbon management, its role in nature and mechanisms regarding the formation and degradation of organic matter. A multidisciplinary techno-economic assessment of current composting standards and laws that took into account the current state of knowledge about carbon management was carried out as a case study. Economic and environmental damage caused by outdated laws was revealed. In addition, it was found that the introduction of the best composts into the market is permitted, causing additional negative environmental as well as economic impacts.

They relate a case of right upper central incisor's hypodontia, describing its clinical and radiographic appearances. Through a large revision of literature about this field, they found out that a disappearance of this element on the human dentition is rare, associating for this: genetic, familiar, nutrient, hormonal, infections and traumatic agents. Finally, they alert for the fact that an accurate clinical examination, complemented by a exact radiographic survey, will make possible a precocious diagnosis and execution of more efficient therapeutic manipulations that reduce the problems of functional, esthetic and phonetics order.

    In this study, we will describe three observations of depression "masked" by persecution delirium and/or hallucinations, to illustrate the role that the cultural factor could play in the expression and care of depression. In the first two observations, the persecutor was a group that was apparently difficult to circumscribe: the persecution appeared more important than the persecutor. In these two cases, persecution also had a depreciating role for the patient. In the third observation, the hallucinatory manifestations cast a slur on self-esteem and caused narcissistic injury. Analysis of the cultural context allows us to understand the depressive significance of such psychotic symptoms. In the traditional societies, depression is strongly related to the cultural context, it is often expressed by the fear of being punished or denied by the group, and a feeling of treason towards the community. The punishment can be direct or indirect, carried out by imaginary beings, "the djinn", or by any disease. According to Freud, the guilt is expressed by the fear of the vengeance of a dead man's spirit, which is then going to persecute the culprit. This persecution, which has a value of punishment, is based on the mechanism of the projection. In the same sense, Freud explained that the death, as a sequel of the disease, is the vengeance of the dead man's spirit in the living. In all religions, the impulses, the thoughts disapproved by the community, are attributed to Satan who etymologically means "the enemy" or "the opponent". This latter plays an important role in relieving fears, the sense of guilt and the disapproved thoughts. There is also involvement of the projection mechanism. So, guilt could be expressed by delirious ideas such as the conviction of being the victim of a demonic possession, to be under a spell or to be persecuted. Thus, taking the cultural context into account would allow us to fundamentally understand the depressive meaning of the delirious

    Full Text Available Sustainability challenges and reactions are not new in the history of human communities but there is a substantial difference between the earlier periods and the present situation: in the earlier periods of human history sustainability depended on the geographic situation and natural resources, today the economic performance and competitiveness are determinative instead of the earlier factors. Economic, social and environmental situations that seem unsustainable could be manageable well if a given land or territory finds that market niche where it could operate successfully, could generate new diversification paths and could create products and services that are interesting and marketable for the outside world. This article is focusing on the sustainability challenges of Macau, China. The case study shows how this special, island-like territory tries to find balance between the economic, social and environmental processes, the management of the present cultural supply and the way that Macau creates new cultural products and services that could be competitive factors in the next years.

    A woman aged 38 was referred to this center for surrogacy treatment, after subtotal ablation of her uterus due to a severe postpartum hemorrhage. Her hormonal profiles and ovarian structure were normal. The husband proved fertile and semen analysis was normal. The carrier, a woman 39 years old, fertile with two children of her own, and a long bonding friendship with the patient. After hormonal stimulation with gonadotropins and GnRH antagonist, six mature oocytes were obtained. These originated four embryos after in vitro fertilization, three of which were transferred to the carrier, achieving a singleton pregnancy which led to the birth of a normal child, now more than a year old. A lawsuit was filed after birth requesting the baby be registered with the biological parents name. The judge granted the request based on evidence and testimonies provided, international jurisprudence history and specification in Article 19 of the Argentine Constitution: "No inhabitant of the Nation shall be obliged to do what the law does not demand .nor be deprived of what it does not prohibit". This is an almost ideal example of the proceedings in a case of subrogation. However, we must always bear in mind the fact that in our country there is as yet no regulatory framework for these treatments, therefore there is a high probability of conflict.

  20. Evolutionary Aspects for Technology Policy: the Case of Galileo Public-Private Partnership

    2002-01-01

    This paper examines the impact of strategic interactions on Private-Public Partnerships (PPPs) in space. Though there is substantial business and economics literature on PPPs, it is traditionally focused on the relationships within the partnerships (low level) and the respective factors affecting its success. The contribution of this paper is that it examines the political economy of PPPs, analysing how `high-level' strategic interactions across public-private sectors in Europe and the US determine their behaviour and success. Within this context, the European case of Galileo and other national space projects, such as the US plans for a space-based anti- missile defence, are each based on different types of PPPs, confined within the geographical borders of the two areas. The security and commercial benefits of such programmes for the respective space industries and economies have a direct impact on the other area's industry and sense of security. The paper shows that trans- Atlantic cooperation at public policy level is essential to allow the respective industries to explore the benefits of cross-border strategic research partnerships (SRPs). This will reduce the costs of the respective programmes, addressing security concerns.

    Full Text Available Introduction. 4H leukodystrophy is an autosomal recessive RNA polymerase III-related leukodystrophy, characterized by hypomyelination, with or without hypodontia (or other dental abnormalities and hypogonadotropic hypogonadism. Case Presentation. We describe a 28-year-old female who presented with primary amenorrhea at the age of 19. She had a history of very mild neurological and dental abnormalities. She was found to have hypogonadotropic hypogonadism, and magnetic resonance imaging of the brain showed hypomyelination. The diagnosis of 4H leukodystrophy was made. She was subsequently found to have mutations in the POLR3B gene, which encodes the second largest subunit of RNA polymerase III. She wished to become pregnant and failed to respond to pulsatile GnRH but achieved normal follicular growth and ovulation with subcutaneous gonadotropin therapy. Discussion. Patients with 4H leukodystrophy may initially present with hypogonadotropic hypogonadism, particularly if neurological and dental manifestations are subtle. Making the diagnosis has important implications for prognosis and management. Progressive neurologic deterioration is expected, and progressive endocrine dysfunction may occur. Patients with 4H leukodystrophy should be counseled about disease progression and about this disease’s autosomal recessive inheritance pattern. In those who wish to conceive, ovulation induction may be achieved with subcutaneous gonadotropin therapy, but pulsatile GnRH does not appear to be effective.

    . Current geothermal drilling practice in Europe is illustrated by three typical case studies. En Europe Occidentale, le forage géothermique est resté longtemps limité au seul champ géothermique de Larderello en Italie pour la production de vapeur sèche. Au cours des dernières années, une expérience plus large s'est accumulée à la suite de l'intensification des programmes d'exploration et de développement entrepris pour évaluer et produire en parallèle les ressources géothermiques haute et basse enthalpies. Un échantillonnage d'une quarantaine de puits indique les sources des problèmes. 1. Forage géothermique basse enthalpie Par suite de situations similaires - système d'eau chaude s'écoulant dans des formations sédimentaires à des tem-pératures s'étalant de 40 à 140 °C et des profondeurs s'étageant de 1000 à 3500 m - la technologie est ici fortement liée à la pratique du forage des puits à huile et à gaz. Cependant, des problèmes spécifiques demeurent dans le domaine de la reconnaissance des réservoirs multiples et de la complétion des puits au niveau de la production et de la réinjection, particulièrement dans les séries fluvio-deltaïques faiblement consolidées amenant des problèmes de contrôle des venues de sables et de gonflement des argiles. Des travaux d'expertise sont nécessaires en vue de diminuer les coûts, d'assurer des capacités de production élevées, de longues durées d'exploitation, des frais de maintenance minimaux compatibles avec l'économie et l'absence de moyens convenables pour les travaux de reprise de puits. 2. Forage géothermique haute enthalpie Le forage d'exploration combine, en langage courant, le forage de recherche et les investigations plus profondes sur les champs connus. Les pertes de circulation, la corrosion des trains de tiges, les tubages, les boues de forage et les cimentations et la maîtrise de la déviation constituent les difficultés les plus fréquemment rencontrées dans les

    Full Text Available In a case study we report on repetitive substorm activity during storm time which was excited during Earth passage of an interplanetary coronal mass ejection (ICME on 18 August 2003. Applying a combination of magnetosphere and ground observations during a favourable multi-spacecraft configuration in the plasma sheet (GOES-10 at geostationary altitude and in the tail lobes (Geotail and Cluster-1, we monitor the temporal–spatial evolution of basic elements of the substorm current system. Emphasis is placed on activations of the large-scale substorm current wedge (SCW, spanning the 21:00–03:00 MLT sector of the near-Earth plasma sheet (GOES-10 data during the interval 06:00–12:00 UT, and magnetic perturbations in the tail lobes in relation to ground observations of auroral electrojets and convection in the polar cap ionosphere. The joint ground–satellite observations are interpreted in terms of sequential intensifications and expansions of the outer and inner current loops of the SCW and their respective associations with the westward electrojet centred near midnight (24:00 MLT and the eastward electrojet observed at 14:00–15:00 MLT. Combined magnetic field observations across the tail lobe from Cluster and Geotail allow us to make estimates of enhancements of the cross-polar-cap potential (CPCP amounting to ≈ 30–60 kV (lower limits, corresponding to monotonic increases of the PCN index by 1.5 to 3 mV m−1 from inductive electric field coupling in the magnetosphere–ionosphere (M–I system during the initial transient phase of the substorm expansion.

  4. Some aspects of metallurgical assessment of boiler tubes-Basic principles and case studies

    Microstructural changes in boiler tubes during prolong operation at high temperature and pressure decrease load bearing capacity limiting their useful lives. When the load bearing capacity falls below a critical level depending on operating parameters and tube geometry, failure occurs. In order to avoid such failures mainly from the view point of economy and safety, this paper describes some basic principles behind remaining life assessment of service exposed components and also a few case studies related to failure of a reheater tube of 1.25Cr-0.5Mo steel, a carbon steel tube and final superheater tubes of 2.25Cr-1Mo steel and remaining creep life assessment of service exposed but unfailed platen superheater and reheater tubes of 2.25Cr-1Mo steel. Sticking of fly ash particles causing reduction in effective tube wall thickness is responsible for failure of reheater tubes. Decarburised metal containing intergranular cracks at the inner surface of the carbon steel tube exhibiting a brittle window fracture is an indicative of hydrogen embrittlement responsible for this failure. In contrast, final superheater tube showed that the failure took place due to short-term overheating. The influence of prolong service revealed that unfailed reheater tubes exhibit higher tensile properties than that of platen superheater tubes. In contrast both the tubes at 50 MPa meet the minimum creep rupture properties when compared with NRIM data. The remaining creep life of platen superheater tube as estimated at 50 MPa and 570 deg. C (1058 o F) is more than 10 years and that of reheater tube at 50 MPa and 580 deg. C (1076 o F) is 9 years

    Different types of exciter are used for voltage supply to the synchronous generators of power stations depending on the required power and design. The exciter system of the generator, which as a rule consists syncronous motors and commutators, is commonly modeled in conventional models by control units with nonlinear characteristics which do not give an accurate picture of the dynamic processes inside the exciter motor. It was not possible to assess the component loads of the exciter components and the physical characteristics within the exciter system. In this study, a brushless exciter for the grid-connected synchronous generator was investigated which consists of two synchronous motors as primary and secondary exciter and two commutator bridges. A dynamic simulation model was developed for calculating the interactions between the grid, generator and exciter unit in consideration of electromagnetic and galvanic coupling. For this, the normal control units were replaced by physical components of the exciter system, i.e. electric exciter motors and commutators. The study was carried out using an enhanced version of the Siemens NETOMAC software, which provided information on the loads on the exciter components in case of internal and external failures. In particular, loads in coils and commutators were calculated that could not be measured before. The findings enable more accurate dimensioning of the exciter unit making it more fail-safe, and the protective systems can be adjusted more accurately. One important result of the investigation was the identification of all dynamic processes going on between the exciter motors, commutators, generator and grid induced by external and internal failures.

    Full Text Available This study examines the ethical-deontological aspects in media coverage of technological disasters, taking as case subject the most important railway accident in Spain of the last 40 years, which took place on the 24 of July 2013 in Santiago de Compostela. To do so, in first place, it presents a systematic review of Spanish selfregulation of journalistic documents related to the coverage of accidents, disasters, in particular technological disasters. Secondly, an analysis of text and photograph is carried out taking as examples four of the most influential online newspapers amongst the Spanish and Galician public media. The results allow us to confirm that deontological transgressions occurred to some extent in all the digital media studied, both in photographs and text. Lastly, a proposal is included with guidelines for a better coverage of technological disasters, using as a reference the findings of previous analysis.

    Full Text Available In the 1990s, the issue of intellectual property rights (IPR protection gained a prominent place on the international trade agenda, which led to the establishment of the trade-related aspects of intellectual property rights (TRIPs as a part of the WTO regime. Two questions are asked regarding this development: whether a multilateral organization such as the WTO performs better than bilateral negotiations in resolving IPR disputes, and what happened around the 1990s to create an environment favorable to the establishment of a multilateral organization. To deal with these issues, this paper takes the IPE (international political economy approach. Using a very simple game theory model, I derive the cases in which a multilateral organization has better performances. Then, it is used to show that political pressures due to the growth of the US trade deficit in the late 1980s could have been the reason that a multilateral organization became the institutional equilibrium.

    To describe all the CT findings after in situ contrast injection just before steroid injection and to recognize the abnormal aspects associated with intravascular contamination. We retrospectively evaluated 248 cervical transforaminal steroid injections done at the university hospital in Dijon, France, in 2008-2012, to treat cervicobrachial neuralgia inadequately improved by optimal medical treatment for at least 3 weeks. Features describing the opacification patterns were recorded. Five main nonvascular opacification patterns were identified: clumps of contrast agent outside the foramen (16 %), a crab claw pattern surrounding the ganglion (13 %), a ''French'' circumflex accent pattern (15 %), reflux along the needle (7 %), and facet joint capsule opacification (22 %). Concerning the situations requiring a change in needle position, intravenous injection occurred in 26 % of the patients, with a crab claw pattern in half the cases and a clump pattern in half the cases. Intraarteriolar injection was noted in two patients. CT after in situ contrast injection ensures proper needle positioning outside the blood vessels before steroid injection. Penetration of the needle tip into a vein is very common, whereas arteriolar puncture is extremely rare. (orig.)

    The Grand Sarcoui is a prominent trachytic volcano of the intraplate Quaternary volcanic field of Chaîne des Puys (Massif Central, France), which fulfills basic requirements for being qualified as monogenetic. Grand Sarcoui looks like a simple axisymmetric lava dome, but close observation reveals a complex and dissymmetric structure and composition. The construction of the dome, about 12.5 ka ago, combined both endogenous and exogenous growth which resulted in variable modes of emplacement and textures of the lava. One of its most interesting features is a large ( 0.29 106 m2) fan of deposits bearing hummocks and secondary hydro-eruption craters. Cross sections of these deposits demonstrate that they originated from a sector collapse accompanied by a blast-like event. The dome is covered by a thin layer of lapilli and ash, attributed to a delayed summit eruption which occurred about 10.6 ka ago, surprisingly late after its construction. So, this volcano has, at a reduced scale, features that are more usually observed in large composite volcanoes. However, some of these features differ slightly from those that have been documented to date, and they remain partly unexplained. This shows that monogenetic, well preserved, trachytic lava domes, are uncommon and poorly known, unlike rhyolitic, andesitic and dacitic domes.

    Full Text Available La multiplicité des introductions ou translocations de poissons, mollusques ou crustacés s'est largement amplifiée dans les dernières décennies et s'est accompagnée de multiples introductions d'agents pathogènes dans les hydrosystèmes naturels. L'analyse de la diversité des sources de ces agents pathogènes montre que certaines voies sont encore largement sous-évaluées aujourd'hui. L'amélioration apportée aux méthodologies et aux techniques d'identification a récemment permis un progrès spectaculaire dans la traçabilité des agents pathogènes et dans l'analyse de leurs introductions. Elle apporte, en partie, les clarifications nécessaires pour tenter de faire le bilan des introductions mais pose nettement le problème du seuil de perception de l'intrus. Une revue de la littérature a permis de recenser environ une centaine d'introductions relativement récentes d'agents pathogènes dans les hydrosystèmes naturels européens. Les caractères biologiques lato sensu favorables à la naturalisation des agents pathogènes introduits sont présentés. La diversité et la non-prédictibilité des impacts consécutifs à ces introductions sont ensuite détaillées à la lumière des études de terrain et de l'écologie théorique de la relation hôte-pathogène. Un cadre conceptuel d'analyse de risque est succinctement délimité pour évaluer ces introductions et des recommandations sont proposées.

    with the desired isotope. The photons emitted by the standard have the same fluorescence intensity and spectral distribution as those produced in the sample itself. After construction, the isolated internal standard is immersed in a pure liquid scintillator solution and counted. A second count is made with the standard immersed in a sample that exhibits colour quenching. The ratio of these two counts is a measure of the colour quenching in the sample and is unaffected by the presence of fluorescence quenching species. Because this method is straightforward in principle and easy to use, it is ideally suited to routine investigations. The individual quenching effects of various sample systems were evaluated by both correction methods. Specially prepared solutions of dyes and samples of urine, blood, and liver tissue were studied extensively. The results show that the agreement between the two methods is excellent. Also, the quenching effects of most of the urine, blood and liver samples could be determined to {+-}3%.

    The general framework of this work is thermal field theory, and more precisely the perturbative calculation of thermal Green`s functions. In a first part, I consider the problems closely related to the formalism itself. After two introductory chapters devoted to set up the framework and the notations used afterwards, a chapter is dedicated to a clarification of certain aspects of the justification of the Feynman rules of the real time formalism. Then, I consider in the chapter 4 the problem of cutting rules in the real time formalisms. In particular, after solving a controversy on this subject, I generalize these cutting rules to the `retarded-advanced` version of this formalism. Finally, the last problem considered in this part is that of the pion decay into two photons in a thermal bath. I show that the discrepancies found in the literature are due to peculiarities of the analytical properties of the thermal Green`s functions. The second part deals with the calculations of the photons or dilepton (virtual photon) production rate by a quark gluon plasma. The framework of this study is the effective theory based on the resummation of hard thermal loops. The first aspects of this study is related to the production of virtual photons, where we show that important contributions arise at two loops, completing the result already known at one loop. In the case of real photon production, we show that extremely strong collinear singularities make two loop contributions dominant compared to one loop ones. In both cases, the importance of two loop contributions can be interpreted as weaknesses of the hard thermal loop approximation. (author) 366 refs., 109 figs.

    To clinically evaluate the horizontal stability of a connective tissue graft (CTG) at the buccal aspect of single implants (1); to compare actual gingival thickness between thin and thick gingival biotype (2). Periodontally healthy non-smoking patients with a single implant in the anterior maxilla (15-25) were selected for a prospective case series. All demonstrated a horizontal alveolar defect and were in need of contour augmentation by means of CTG for aesthetic reasons. Patients were enrolled 3 months after implant surgery and had been provided with a provisional screw-retained crown. CTG was inserted in the buccal mucosa via the envelope technique using one intrasulcular incision. An ultrasonic device was used to evaluate mucosal thickness (MT) at the buccal aspect. MT was assessed at t0 (before CTG), t1 (immediately after CTG), t2 (2 weeks after CTG = suture removal), t3 (3 months after CTG = permanent crown installation) and t4 (1 year after implant placement). The gingival biotype was categorized as thin or thick based on the transparency of a periodontal probe through the soft tissues while probing the buccal sulcus of the contra-lateral tooth. Gingival thickness (GT) was measured at the contra-lateral tooth using the same ultrasonic device. Thirty-seven patients (19 men, 18 women; mean age 38) met the selection criteria and consented to the treatment. Mean soft tissue gain immediately after CTG was on average 1.07 mm (SD 0.49). What remained of this tissue gain after 1 year was on average 0.97 mm (SD 0.48; 90.5%). Hence, mean soft tissue loss amounted to 0.10 mm (SD 0.23; 9.5%; p = 0.015) with no significant difference between patients with a thin or thick biotype (p ≥ 0.290). Patients with a thin biotype had a mean GT of 1.02 mm (SD 0.21), whereas GT was on average 1.32 mm (SD 0.31) in subjects with a thick biotype (p = 0.004).

    Radiation protection practices for handling reactor fuel elements are described. Elements of considerable specific radioactivity are handled under water. A study was made of water filtration and of ventilation in the building. The installations are divided up into zones depending on the radioactive risks, and the radiation level atmospheric contamination are the object of a systematic control at various points. A description is given of all aspects of health physics which have been encountered during six years: storage, transfer of radioactive material; decladding, rolling, waste disposal, specialized operations, installations in operation and at rest, and transport. In spite of the gradual increase in the activity of these installations, the total doses received by the personnel have hardly altered and the number of cases of physical contamination has diminished.

    Amrani, Salah

    La fabrication de l'aluminium est realisee dans une cellule d'electrolyse, et cette operation utilise des anodes en carbone. L'evaluation de la qualite de ces anodes reste indispensable avant leur utilisation. La presence des fissures dans les anodes provoque une perturbation du procede l'electrolyse et une diminution de sa performance. Ce projet a ete entrepris pour determiner l'impact des differents parametres de procedes de fabrication des anodes sur la fissuration des anodes denses. Ces parametres incluent ceux de la fabrication des anodes crues, des proprietes des matieres premieres et de la cuisson. Une recherche bibliographique a ete effectuee sur tous les aspects de la fissuration des anodes en carbone pour compiler les travaux anterieurs. Une methodologie detaillee a ete mise au point pour faciliter le deroulement des travaux et atteindre les objectifs vises. La majorite de ce document est reservee pour la discussion des resultats obtenus au laboratoire de l'UQAC et au niveau industriel. Concernant les etudes realisees a l'UQAC, une partie des travaux experimentaux est reservee a la recherche des differents mecanismes de fissuration dans les anodes denses utilisees dans l'industrie d'aluminium. L'approche etait d'abord basee sur la caracterisation qualitative du mecanisme de la fissuration en surface et en profondeur. Puis, une caracterisation quantitative a ete realisee pour la determination de la distribution de la largeur de la fissure sur toute sa longueur, ainsi que le pourcentage de sa surface par rapport a la surface totale de l'echantillon. Cette etude a ete realisee par le biais de la technique d'analyse d'image utilisee pour caracteriser la fissuration d'un echantillon d'anode cuite. L'analyse surfacique et en profondeur de cet echantillon a permis de voir clairement la formation des fissures sur une grande partie de la surface analysee. L'autre partie des travaux est basee sur la caracterisation des defauts dans des echantillons d'anodes crues

    The authors deal successively with the industrial production of fuel elements for power reactors of the natural uranium-graphite-gas type, and more particularly for the EDF power stations, and with the industrial production of fuel elements containing enriched uranium designed for swimming-pool type reactors. 1. part: advanced fuel elements for the EDF reactors. After recalling the characteristics of the fuel elements now being produced industrially for the Marcoule and Chinon reactors, the authors give the various steps leading to the industrial production of a new type of fuel element both as concerns the can, and in certain cases the graphite sleeve, and the fuel itself. As for as the production of the fuel is concerned, they describe the various operations, stressing the original aspects of the production and of the equipment such as: - casting in hot moulds, - thermal treatments, of Uranium containing 1% in weight molybdenum, - welding of the pellets for closing the tubes of uranium, - canning, - controls in the various steps. As far as can production is concerned they show why the extruded can was replaced by a machined can and give a few characteristics of the equipment used as well as the controls effected. They give also some details concerning the production and machining of the sleeves. After recalling the state of the nuclear fuel industry in France in mid-1964 the authors stress the economic aspects of the production of fuel elements. They show the relative importance of capital costs on the cost price of the fuel itself and examine the various items involved. They analyse the cost price of a completed fuel element using present date knowledge. In conclusion the authors show the particular points which should be the subject of future efforts in order to decrease the cost of a production which is perhaps delicate but now will define, and review the development of this new industrial branch. 2. part: industrial production of fuel elements for swimming

    This work concerns the changes in the spectral sensitivity of 3 types of normal photo-cathodes (Cs{sub 3}Sb, tri-alkali and bi-alkali without cesium) as a function of temperature. The photo-cathodes of cathodes of commercial photomultipliers (DARIO, E.M.I., R.C.A., A.S.C.O.F.) were used for these tests. The temperature range studied was -25 C to +55 C (except for the bi-alkali photo-cathodes which were tested up to +150 C) and the wave-length range was 3250 to 7000 angstrom. After a brief review of photo-electric effect theories, the experimental device is described and the measurement results presented. Finally, an interpretation of these results is proposed. For the normal range of scintillator emission, i.e. between 3000 and 5000 angstroms (Na I (Tl), plastics, anthracene) the temperature coefficient is always negative: -0.15 % C for Cs{sub 3}Sb and up to -0.5 % C for the most temperature-sensitive photo-cathode. Above 5000 angstrom, the temperature coefficient of Cs{sub 3}Sb films becomes positive: +0.5 % C on the overage. The accuracy of the spectral sensitivity measurements is {+-}4 % in absolute value and {+-}1 % in relative value.

    After a bibliographic analysis of the probable causes of isotopic effects and their comparison, with the simplifications provided by the athermal model, a discussion of the isotopic effect of deuterium in organic molecules in terms of structural influences is presented, showing the important role of the C-D bond length which is shorter than the C-H bond length, and of the D atom's Van der Waals radius, shorter than that of the H atom. Kinetic measurements were carried out on some reactions involving the mechanisms proposed: unimolecular ionizations and halogen concentrates. The structural models chosen are: 2-chloro-cyclo-hexanols cis and trans 1-H and 2-D; 2-chloro-cyclo-pentanols cis trans 1-H and 1-D; 1-phenyl-l-chloro-2-propanol threo 2-H and 2-D.

    Disposal of radioactive wastes in marine waters allows for an accumulation of radioactivity by marine life. Such an accumulation by seafood organisms might affect their utilization or availability. Laboratory studies of accumulation of important radionuclides present in different wastes by marine plankton, benthic invertebrates and various species of marine fish and of the biological effects of accumulated radioactivity on these forms are being conducted at Beaufort, North Carolina, as a co-operative activity of the US Atomic Energy Commission and the US Bureau of Commercial Fisheries. These investigations help provide essential information for the formulation of waste disposal practices and the safe operation of nuclear-powered ships in coastal waters. They are useful also in the development of monitoring programmes designed to detect and evaluate hazards from accidental pollution of inshore waters. (author) [French] L'elimination des dechets radioactifs dans la mer fait la part d'une accumulation d'activite dans les organismes vivant dans ce milieu. Cette accumulation dans les produits comestibles de la mer peut nuire a leur utilisation ou a leur abondance.

    Full Text Available Les mobilités pendulaires semblent être en augmentation en Europe depuis une dizaine d’années. Cette croissance du temps passé à se déplacer amène à remettre en question la conjecture de Zahavi et apparaît relativement inexplicable en regard du paradigme classique de l’acteur rationnel traditionnellement utilisé dans le champ des transports. Si, dans la littérature, les temps de déplacements sont principalement expliqués par le contexte résidentiel, la forme urbaine et le travail, ce cadre explicatif ne dit rien des processus de décision eux-mêmes qui amènent aux pendularités intensives.À partir d’une enquête qualitative menée auprès de pendulaires français, suisses et belges, cette contribution propose d’analyser les arbitrages et les éléments déterminants des processus de la grande pendularité. Les mobilités quotidiennes pendulaires apparaissent comme le résultat de compromis entre activité professionnelle, attachement résidentiel et choix de vie et prennent ainsi la forme de stratégies de conciliation entre vie privée et vie professionnelle. Ces mobilités spatiales permettent alors paradoxalement la préservation des ancrages résidentiels, sociaux et familiaux.Roots and wings.

These raising mobility patterns lead to reappraise the Zahavi conjecture and appear largely inexplicable by the classical rational actor paradigm traditionally used in transportation research. In literature, commuting is mainly explained by residential contexts, urban forms and job. Nevertheless this theoretical frame says little about the decision-making processes themselves.

    Life Cycle Assessment is a tool to assess, in a systematic way, the environmental aspects and its potential environmental impacts and resources used throughout a product's life cycle. It is widely accepted and considered as one of the most powerful tools to support decision-making processes used in ecodesign and sustainable production in order to learn about the most problematic parts and life cycle phases of a product and to have a projection for future improvements. However, since Life Cycle Assessment is a cost and time intensive method, companies do not intend to carry out a full version of it, except for large corporate ones. Especially for small and medium sized enterprises, which do not have enough budget for and knowledge on sustainable production and ecodesign approaches, focusing only on the most important possible environmental aspect is unavoidable. In this direction, finding the right environmental aspect to work on is crucial for the companies. In this study, a multi-criteria decision-making methodology, Analytic Network Process is proposed to select the most relevant environmental aspect. The proposed methodology aims at providing a simplified environmental assessment to producers. It is applied for a hand blender, which is a member of the Electrical and Electronic Equipment family. The decision criteria for the environmental aspects and relations of dependence are defined. The evaluation is made by the Analytic Network Process in order to create a realistic approach to inter-dependencies among the criteria. The results are computed via the Super Decisions software. Finally, it is observed that the procedure is completed in less time, with less data, with less cost and in a less subjective way than conventional approaches. - Highlights: • We present a simplified environmental assessment methodology to support LCA. • ANP is proposed to select the most relevant environmental aspect. • ANP deals well with the interdependencies between aspects

    Full Text Available Purpose: To provide insights into the energy requirements as well as the physiological adaptations of an experienced 50-year-old ultra-marathon male athlete during the world's most challenging mountain ultra-marathon (MUM.Methods: The international race supporting the study was the Tor des Geants®, characterized by 330 km with +24,000 m D+ to be covered within 150 h. Before the MUM, we assessed the peak oxygen uptake (V˙O2peak by means of an incremental graded running test. During the MUM we monitored six ascents (once per race day with a portable gas analyzer, a GPS and a finger pulse oximeter. We then calculated the net metabolic cost per unit of distance (C, the vertical metabolic cost (Cvert and the mechanical efficiency of locomotion (Effmech throughout the six uphills monitored. We further monitored the distance covered, speed, altimetry and D+ from the GPS data as well as the pulse oxygen saturation with the finger pulse oximeter.Results: Subject's V˙O2peak was 48.1 mL·kg−1·min−1. Throughout the six uphills investigated the mean exercise intensity was 57.3 ± 6.0% V˙O2peak and 68.0 ± 8.7% HRpeak. C, Cvert and Effmech were 11.4 ± 1.9 J·kg−1·m−1, 57.9 ± 15.2 J·kg−1·mvert−1, and 17.7 ± 4.8%, respectively. The exercise intensity, as well as C, Cvert, and Effmech did not consistently increase during the MUM.Conclusions: For the first time, we described the feasibility of assessing the energy requirements as well as the physiological adaptations of a MUM in ecologically valid environment settings. The present case study shows that, despite the distance performed during the MUM, our participant did not experience a metabolic fatigue state. This is likely due to improvements in locomotor efficiency as the race progressed.

  20. Modeling Aspect Controlled Formation of Seasonally Frozen Ground on Montane Hillslopes: a Case Study from Gordon Gulch, Colorado

    The Intergovernmental Panel on Climate Change (2013) warns that high-elevation ecosystems are extremely vulnerable to climate change due to short growing seasons, thin soils, sparse vegetation, melting glaciers, and thawing permafrost. Many permafrost-free regions experience seasonally frozen ground. The spatial distribution of frozen soil exerts a strong control on subsurface flow and transport processes by reducing soil permeability and impeding infiltration. Accordingly, evolution of the extent and duration of frozen ground may alter streamflow seasonality, groundwater flow paths, and subsurface storage, presenting a need for coupled thermal-hydrologic models to project hydrologic responses to climate warming in high-elevation regions. To be useful as predictive tools, such models should incorporate the heterogeneity of solar insolation, vegetation, and snowpack dynamics. We present a coupled thermal-hydrologic modeling study against the backdrop of field observations from Gordon Gulch, a seasonally snow-covered montane catchment in the Colorado Front Range in the Boulder Creek Critical Zone Observatory. The field site features two instrumented hillslopes with opposing aspects: the snowpack on the north-facing slope persists throughout much of the winter season, while the snowpack on the south-facing slope is highly ephemeral. We implemented a surface energy balance and snowpack accumulation and ablation model that is coupled to the subsurface flow and transport code PFLOTRAN-ICE to predict the hydrologic consequences of aspect-controlled frozen soil formation during water years 2013-2016. Preliminary model results demonstrate the occurrence of seasonally-frozen ground on the north-facing slope that directs snowmelt to the stream by way of shallow subsurface flow paths. The absence of persistently frozen ground on the south-facing slope allows deeper infiltration of snowmelt recharge. The differences in subsurface flow paths also suggest strong aspect

  2. Aspects and mechanisms of austenitic stainless steel corrosion in case of sodium leaks under mineral wool insulation

    International Nuclear Information System (INIS)

    Bertrand, C.; Ardellier, A.

    1996-01-01

    Sodium pipe rupture tests representative of Fast Reactors Accidents have been carried out on austenitic stainless steel surfaces. These tests improve our knowledge of small sodium leakage propagation in mineral wool insulation. They explain the new and unexpected aspects of the crevice corrosion phenomenon which has been observed on austenitic stainless steel pipe surfaces. Experimental results show that corrosion is limited to a peripheral annular zone, which extends out in concentric waves. The diameter of this corrosion zone is practically constant. Tests show that sodium does not expand directly on the pipe surface. Sodium sprays through mineral wool insulation, where chemical reaction between silica fibers, occluded oxygen and water vapor occur at the same time. Simultaneously, there is a diffusion phenomenon of liquid Na droplets on the mineral wool fibers. The study allows to prove the electrochemical nature of the corrosion. The excess liquid Na, spraying as droplets induces an anodic dissolution mechanism by differential aeration. This phenomenon explains the random microscopic and macroscopic aspects of material removal. (authors). 1 ref., 16 figs

    We have been forced by the rough competition on the liberalised power market, especially in the last 15 months, to shut down our unit II, a 345 MW el. combined unit with gas turbine with following 750 t once-through boiler (Benson-type) and an efficiency of 44%, for a shorter or longer period of time. At the same time, availability must be ensured to cope with the price situation/development on the power market. Out of this difficult situation we developed a lay-up concept which allows shutdowns from one week up to six months and the restart within 75 hours. (orig.) [German] Durch die harten Wettbewerbsbedingungen des liberalisierten Strommarktes in Deutschland wurden wir gerade in den letzten beiden Jahren gezwungen, unser Kraftwerk II ueber kuerzere oder laengere Zeitraeume stillzulegen.

    suspending medium may either compete for radicals, e.g. most foods and microbiological media are radical scavengers, or it may promote formation of harmful radicals, e. g. phosphate buffer forms phosphinic acid, oxygen forms peroxy and perhydroxye radicals. Changes of D{sub 10}-values of an individual strain caused by various environmental conditions can be related to indirect effects, while changes of D{sub 10} values from strain to strain under standardized conditions relate to the amount and structure of nucleoid DNA in spores. In this respect all strains of C. botulinum studied to date can be tentatively divided into three groups: Group 1 includes strains (A, B and E) with D values around 0.13 Mrad or less. These spores exhibit single-hit inactivation curves and have probably one chromosome with a low repair probability. Group 2 includes strains 12885 A, 62A, 77A, 9B clustering around D{sub 10} =0.23 Mrad. Available target data suggest that these spores possess one chromosome of 900 {mu} with a repair multiplicity of 13. Group 3 includes the highly-resistant strains 33A, 36A, 40B, 41B, and 53B clustering around D{sub 10} = 0.33 Mrad. Available target data suggest that these spores possess two chromosomes of 900{mu} each with a repair multiplicity (N) between 80 and 90, i.e. N = 13{sup 2}/2.

    Can-rupture detection (DRG) is one important aspect of pile safety, more particularly so in the case of gas-cooled reactors. A rapid and sure detection constitutes also an improvement as far as the efficiency of electricity-producing nuclear power stations are concerned. Among the numerous can-rupture detection methods, that based on the measurement of the concentration of short-lived fission gases in the heat-carrying fluid has proved to be the most sensitive and the most rapid. A systematic study of detectors based on the electrostatic collection of the daughter products of fission gases has been undertaken with a view to equip the reactors EL 2, G 3, EDF 1, EDF 2 and EDF 3, the gas loops of PEGASE and EL 4. The different parameters are studied in detail in order to obtain a maximum sensitivity and to make it possible to construct detection devices having the maximum operational reliability and requiring the minimum maintenance. The primary applications of these devices are examined in the case of the above-mentioned reactors. (author) [French] La Detection des Ruptures de Gaines (D. R.

    Saad, Samir.

    1995-10-01

    The present study presents severalk aspects related to the phosphate industry from the origin of the raw materials to the final products. Emphasis is given in the approach of problems associated with the radiological impact and inherent risks when non monitorated products are used. Considerations are made on geological, geochemical and radiometrical characteristics of the main world deposits of phosphatic rocks. The critical patways of U-238 and Th-232 radionuclides are analysed from its origin to the final products. World-wide statistical data on several industrial phosphate branches are presented, and suggestions are made to draw attention to governmental organizations on the need for establishing specific technological development programs for the extraction of radionuclides from phosphate industrial products. The Itataia's project of industrial mining and milling, located in the state of Ceara, is focused here in great detail considering that is represents one of the biggest world concentrations of uranium associated with phosphatic rocks. Results from field studies performed in Itataia's mine are presented and analytical results from laboratory studies in samples from Itataia's (CE) and Barreiro's (MG) phosphatic rocks and Guaramicim's (PE) phospholite are also discussed. Finally, the study proposes a series of necessary actions to implement a national environmental monitoring plan i order to minimize the risks due to the radioactivity arising from phosphatic rocks and from derived fertilizers industry.

Jusqu'alors fonction technique, centrée autour de l'achat de couverture d'assurances, elle est devenue une discipline managériale et transversale : une valise d'instruments que chaque manager doit connaître et appliquer quels que soient son domaine de compétence et ses missions au sein de l'organisation. En effet, la gestion des risques est une culture qui doit être assimilée par chacun des acteurs. C'est précisément l'ambition des 101 questions rassemblées dans cet ouvrage : apporter à chaque manager d'entreprise, de collectivité, d'établissement de santé..., des réponses claires au " pourquoi " et au " comment " : Comment identifier les risques ? Comment analyser les risques ? Quels sont les objectifs de la gestion des risques ? Une carte des risques pour quoi faire ? Pourquoi faut-il financer les risques ?

    Supplementary non-inductive current drive and heating are necessary to bring Tokamak plasmas into the ignition regime. The resonant excitation of shear Alfven waves (SAW) - in the continuum range (CR) or/and in the discrete global Alfven eigenmode spectrum (GAE's) - represents one potential, suitable method for this purpose. Within the framework of ideal MHD, the current drive (CD) via helicity injection in Tokamak plasmas has been considered by Cuperman et al (1996) and Komoshvili et al. (1996). This work is concerned with the investigation of the non-ideal resistive MHD effects on both the excitation of SAW's (CR's and GAE's) and the generation of non-inductive current drive via helicity injection in Tokamak plasmas. The research covers Tokamak aspect ratios ranging between large value cases (R/a = 10) and the very tight value case (R/ a = 1.2). (authors)

    2013-01-01

    Full Text Available At the time when the Hague Convention on the Civil Aspects of International Child Abduction was passed, that was a very logical step and a goal that this Conventionis set before it, and that is prompt return of children wrongfully removed or retained children, was a necessary consequence of the circumstances of that time. Namely, in most cases, men, that is fathers, were those, who illegally took or kept the children. More than thirty years later, the situation in that field has changed in the sense that mothers are now abductors in most cases, mostly seeing that this is the only way to escape from the violence they, or their children, are facing with. In that sense, the question is whether the achievement of the objective of this Convention is still justified, that is would it be justified any other interpretation of the Convention in situations where the unlawful removal or retention of children is a result of domestic violence.

    Full Text Available Natural hazards do have impacts on development. Of heavy consequences on both the human life and the economic development these impacts are critical in most of the Caribbean islands in general and specifically in Haiti. Thus, there is an urgent need to implement strategies aiming at reducing risk for lessening losses. By implementing well designed risk management strategies vulnerability can be reduced, and as a consequence, investment and employment can be protected. Even so preparedness to sustainable development is at the global Agenda, with regards to the specific case of Haiti, we assume that, at present, the country is not at all involved in such a long run strategy. Government attention is focused on immediate urgencies to be solved. By questioning the particular case of tourism, we show the positive impact of risk management strategies on growth using a Cost-Benefit Analysis (CBA.Les catastrophes naturelles ont sans conteste des impacts sur le développement. Ces derniers, qui occasionnent de lourdes conséquences à la fois sur la vie humaine et le développement économique, sont préjudiciables dans la plupart des îles des Caraïbes et plus particulièrement en Haïti.

    2017-08-01

    Metallic mercury may be self-injected for suicidal or self-harm purposes or sometimes for superstitious or other inadvisable reasons. Local tissue or systemic consequences such as mercurialism can frequently occur in cases of subcutaneous or deep injection, while death due to pulmonary embolism and cardiac, brain, hepatic or renal toxicity may occur in cases of high dosage intravenous administration. The aim of this review is to focus on the diagnostic difficulties facing coroners and forensic pathologists when the courts require confirmation that evidence of self-injection of metallic mercury is the result of suicide or self-harming. Forensic examination performed on the corpses of victims who died in or out of hospital or on surviving injured or intoxicated victims showing signs of mercurialism, demands the careful evaluation of the death scene, of all related circumstances and of the clinical and autopsy data. Close interaction between forensic pathologists and toxicologists is also needed to identify and quantify mercury levels in blood, urine and tissue.

    Full Text Available This paper presents the impact of the collected VAT on a company acting in the construction field in the current economic environmnet; the study is based on data provided by the company before and after applying the VAT collection system. The research reflects the VAT payable on State Budget three times: before its entry into the system, its activity during the application system and its situation in 2014 when the company can choose between staying in the system or getting out of it. The research method consisted in reviewing approaches made in the literature, articles and specialized studies in national and international journals. We followed a detailed approach of the effects generated by the VAT collection system among companies acting in the construction filed and we made a case study based on the activity of the construction companies before applying the system and their option to stay or exit the VAT collection system.

  3. Diagnostic abilities of three CAD methods for assessing microcalcifications in mammograms and an aspect of equivocal cases decisions by radiologists

    Hung, W.T.; Nguyen, H.T.; Thornton, B.S.; Rickard, M.T.; Blinowska, A.

    2003-01-01

    Radiologists use an 'Overall impression' rating to assess a suspicious region on a mammogram. The value ranges from 1 to 5. They will definitely send a patient for biopsy if the rating is 4 or 5. They will send the patient for core biopsy when a rating of 3 (indeterminate) is given. We have developed three methods to aid diagnosis of cases with microcalcifications. The first two methods, namely, Bayesian and multiple logistic regression (with a special 'cutting score' technique), utilise six parameter ratings which minimise subjectivity in characterising the microcalcifications. The third method uses three parameters (age of patient, uniformity of size of microcalcification and their distribution) in a multiple stepwise regression. For both training set and test set, all three methods are as good as the two radiologists in terms of percentages of correct classification. Therefore, all three proposed methods potentially can be used as second readers. Copyright (2003) Australasian College of Physical Scientists and Engineers in Medicine

The following transmission routes were involved: triatominae in 7 cases, blood transfusion in 9, kidney transplantation and/or blood transfusion in 4, accidental in 1, oral route in 3, probably breast feeding in 1, congenital or breast feeding in 1, and congenital or blood transfusion in 1. Six patients infected by triatominac acquired the disease between 1974 and 1980 and one in 1987. The blood transfusion infected patients acquired the disease in Greater São Paulo, seven of whom after 1983. The acute phase Chagas' disease was oligosymptomatic in 4 patients: three of such patients being immunocompromised by drugs or other diseases. Another two adult immunocompromised patients developed myocarditis and congestive heart failure. Clinical features were severe in 5 from 6 children under two years, irrespective of the transmission route. Evaluation of the acute phase patients treated with benznidazol (4-10 mg/kg/day) showed: therapeutic failure in 4/16 (25.0%); possible cure in 9/16 (53.2%) and inconclusive results in 3/16 (18.8%). The antibody and complement-mediated lysis reaction was in keeping with the xenodiagnosis in 18/22 cases, having shown negative results after treatment earlier than classical serological reactions. One aplastic anaemia patient receiving corticosteroid presented lymphoproliferative disease 6 years after being treated with benznidazol for acute Chagas' disease.

    For the weakness analysis of the containment under internal pressure a question that arose was at what pressure the seal casing for the equipment hatch will fail. For this investigation model strips of the seal casing cross section were manufactured as tensile specimens. Variations of the seal plates welding seams were considered and tested. The type of failure and the associated deformations and resulting forces were measured for 6 specimens. (orig.)

    Full text: The work is aimed at developing a decision making strategy and tools for putting into practice the principles of reasonableness and optimization when applying countermeasures in case of a radiation related accident at a nuclear power plant in RF. The presentation discusses results of the study of the legal framework in the RF for decision making to protect the personnel and public in case of a radiation-related accident Consideration is given to issues of methodological support for emergency response systems at NPPs, as required by the RF radiation safety norms to protect personnel and the public. This work was performed as part of methodological support to the national emergency center of Rosenergoatom comprising several technical support centers on the base of leading institutes with large scientific potential in the fields of nuclear power use, environmental and public protection, radioecology etc. Such centers were set up for scientific and technical support to decision making in case of emergency at NPPs. Specialists of die centers are able to quickly assess the emerging situation and propose a set of measures to minimize damage, drawing on expert judgements. The radiation safety guidelines (NRB-99) lays down requirements and criteria for decision making to protect the public in different phases of a radiation accident which should be used when implementing countermeasures and developing emergency response plans with allowance for specific situation and local conditions. These criteria provide a basis for designating areas of emergency response that would be optimum for specific population points, intervention measures etc. Dealing with these tasks requires development of normative and methodological documentation taking into account both the NRB-99 requirements and international recommendations. In accordance with NRB-99: expected and averted radiation doses are the key criteria to be used in application of any protection measures in radiation

    2016-10-01

    Full Text Available This article situates Auden’s poem Musée des Beaux Arts in the process of his conversion to Christianity. The author argues for the layered intertextuality of the poem, in which allusions to Bruegel’s Landscape with the Fall of Icarus, The Census at Jerusalem, and The Massacre of the Innocents can be recognised. Moreover, Philippe de Champaigne’s Presentation in the Temple and Peter Paul Rubens’s The Martyrdom of St Livinus (in the same museum in Brussels seem also to have influenced the poem. Finally, there is reason to suppose that John Singer Sargent’s Crashed Aeroplane influenced Auden. In an analysis of the structure of the poem, the author argues that there is a clear structure hidden under the surface of day-to-day language. He connects this hidden structure with Auden’s poem The Hidden Law, and suggests that Auden wished to claim that even though we cannot understand suffering, it has a hidden meaning known only to God. This hidden meaning connects our suffering with the self-emptying of Christ, a connection which the author demonstrates is in fact also made in Musée des Beaux Arts.

    Full Text Available The overall question of when amendments to an existing agreement are to be regarded as constituting a new award of a public contract has not come before the ECJ. The Pressetext case and decision’s practice in the Czech Republic has solved this question: In order to ensure transparency of procedures and equal treatment of tenderers, amendments to provisions of a public contract during the currency of the contract constitute a new award of a contract when they are materially different in character from the original contract and, therefore, are such as to demonstrate the intention of the parties to renegotiate the essential terms of that contract. We can say that for this purpose an amendment to a public contract may be regarded as ‘material’ when: it introduces conditions which, had they been part of the initial award procedure, would have allowed for the admission of tenderers other than those initially admitted, or would have allowed for the acceptance of a tender other than the one initially accepted, it extends the scope of the contract considerably to encompass services not initially covered and it changes the economic balance of the contract in favour of the contractor in a manner which was not provided for in the terms of the initial contract.

    2010-01-01

    The right of a person to be protected from natural hazards is a characteristic of the social and economical development of the society. This paper is a contribution to the reflection about the role of Civil Protection organizations in a modern society. The paper is based in the inaugural conference made by the authors on the 9th Plinius Conference on Mediterranean Storms. Two major issues are considered. The first one is sociological; the Civil Protection organizations and the responsible administration of the land use planning should be perceived as reliable as possible, in order to get consensus on the restrictions they pose, temporary or definitely, on the individual free use of the territory as well as in the entire warning system. The second one is technological: in order to be reliable they have to issue timely alert and warning to the population at large, but such alarms should be as "true" as possible. With this aim, the paper summarizes the historical evolution of the risk assessment, starting from the original concept of "hazard", introducing the concepts of "scenario of event" and "scenario of risk" and ending with a discussion about the uncertainties and limits of the most advanced and efficient tools to predict, to forecast and to observe the ground effects affecting people and their properties. The discussion is centred in the case of heavy rains and flood events in the North-West of Mediterranean Region.

    South Africa desperately needs a comprehensive approach to fight HIV/AIDS. Education is crucial to reach this goal and Internet and e-learning could offer huge opportunities to broaden and deepen the knowledge basis. But due to the huge societal and digital divide between rich and poor areas, e-learning is difficult to realize in the townships. Community health workers often act as mediators and coaches for people seeking medical and personal help. They could give good advice regarding hygiene, nutrition, protection of family members in case of HIV/AIDS and finding legal ways to earn one's living if they were trained to do so. Therefore they need to have a broader general knowledge. Since learning opportunities in the townships are scarce, a system for e-learning has to be created in order to overcome the lack of experience with computers or the Internet and to enable them to implement a network of expertise. The article describes how the best international resources on basic medical knowledge, HIV/AIDS as well as on basic economic and entrepreneurial skills were benchmarked to be integrated into an e-learning system. After tests with community health workers, researchers developed recommendations on building a self-sustaining system for learning, including a network of expertise and best practice sharing. The article explains the opportunities and challenges for community health workers, which could provide information for other parts of the world with similar preconditions of rural poverty. © The Author(s) 2015.

    2009-01-01

    The paper summarizes the results of a study concerning the operation of industrial plants and their effects to the environment. It also addresses, shortly, the consequences to the quality of human life and proposes potential measures that may contribute to the reduction of the negative environmental impacts. The relatively small organized Industrial Area of Alexandroupolis (Greece) is examined as a case study. In particular, the activities of its major industrial facilities are presented and their emissions to the environment are examined. In addition, the socio-economic aspects of the operation of the Industrial Area are studied. The results of the study showed that the operation of the Industrial Area has specific negative effects in the natural environment of the region and in the quality of life of the residents. Methodological and legislative tools, such as control systems for the environmental pollution, the green chemistry, and the environmental management systems, may be employed to assist the prevention and confrontation of environmental problems

    Shaft lines of turbo-machineries have to stand increasing reliability, efficiency and safety requirements. A precise modeling of the rotating parts with all possible coupling has become necessary. In this context, this work aims to develop a global modeling of rotating wheel/shaft system inside a surrounding fluid in order to foresee its dynamical behaviour. The use and advantage of Eulerian, Lagrangian and mixed (arbitrary Lagrangian Eulerian - ALE) formulations is recalled first. A bibliographic synthesis of the classical techniques used in structure mechanics and of coupling techniques for rotating machines is presented. The coupling technique retained is presented. It uses fluid and structure models independently developed and validated. The structure domain is discretized by the finite-element method. The fluid domain is discretized by the finite-difference method taking into consideration the hypotheses linked with thin films. A modal base projection combined with a mesh at the fluid-structure interface allows an efficient, adaptable and evolutive coupling. Finally, the method is applied to 3 test-cases. The first two ones comprise a shaft/disc system coupled to a fluid sheet between the disc and the casing and to an hydrodynamic bearing. Both cases allow a first validation of the coupling method. The third case aims to study a structure closer to a real system made of a shaft and a wheel coupled to a fluid sheet between a flange and a casing. These three applications allow to show the trends linked with the fluid effects and the coupling between the flexible sub-parts of the structure. (J.S.)

    Full Text Available The doctrine of estoppel precludes a person (asserter from asserting something different or contrary to what is implied by a previous action, conduct or statement of that person or by a previous pertinent judicial determination. While there are various types of estoppel, this article is primarily focused on the application of issue estoppel in relation to certain aspects of the directors’ fiduciary duties in South Africa (s 76 of the Companies Act 71 of 2008 (Companies Act 2008, in light of the judgment in Royal Sechaba v Coote (366/2013 [2014] ZASCA 85 (30 May 2014 (Royal Sechaba case. Issue estoppel could be defined to include instances where a person is precluded from re-litigating or raising a particular issue in a cause of action that was previously decided by a final judgment of a competent court between the same parties in future cases that have a different cause of action involving such parties. Issue estoppel is closely related to res judicata. For instance,both issue estoppel and res judicata are generally aimed at preventing the re-litigation of the same issues and same cause of actions that were previously decided by a final judgment in the relevant courts between same parties. Nonetheless, it is widely acknowledged that the application these two concepts is quite different in practice. For instance, some jurisdictions such as the United Kingdom (UK and South Africa employs English law and Roman-Dutch law (common law principles respectively, to distinguish between issue estoppel and res judicata. Likewise, similar common law principles are employed in the United States of America (USA, Canada and Australia to distinguish res judicata and issue estoppel in various ways. For example, issue estoppel is sometimes referred to as collateral estoppel, issue preclusion, claim preclusion or cause of action estoppel in USA, Canada and Australia. Despite this, it should be noted that a detailed discussion of the different requirements, merits

    The study of the leaching of heaped uranium ore can be considered theoretically as the problem of the diffusion of liquids in porous bodies and in particular as that of its influence on the chemical reaction rates of conventional uranium oxides. Below a certain value of the pore diameter, it is diffusion which is responsible for mass transfer. The porous structure can be characterized by various physical constants which modify the free diffusion equation and, as long as the pores have a diameter greater than a few microns, it can be shown that the pore walls have a negligible effect on the diffusion. The diffusion coefficients for the nitrate, the sulfate, the chloride, the acetate and the perchlorate of uranium have been determined. In the case of the reaction of uranium trioxide with acids in a porous body, the reaction kinetics are governed by the arrival of the reagent by diffusion. The attack of uranium dioxide by an acid ferric iron solution has been studied under the same conditions and it has been found that the diffusion modifies the influence of the ferrous and ferric iron concentrations on the reaction kinetics. The same is true for the oxide U{sub 3}O{sub 8}. All the results concerning these reactions studied in the absence of the influence of diffusion should be modified to take this factor into account when it intervenes in an extraction process. (authors) [French] L'etude de la lixiviation en tas d'un minerai d'uranium peut se ramener theoriquement au probleme de la diffusion des liquides dans les corps poreux et en particulier a celui de son influence sur les vitesses de reaction chimique des oxydes classiques de l'uranium. En dessous d'une certaine limite de diametre des pores la diffusion est responsable du transfert de masse. La structure poreuse peut se caracteriser par differentes constantes physiques qui modifient l'equation de la diffusion libre et tant que les pores ont un diametre superieur a quelques microns, on a montre que l

    A review is made of the circumstances which favor a good collection of maintenance data at the C.E.A. The large amount of data to be treated has made necessary the use of a computer for analyzing automatically the results collected. Here, only particular aspects of the reliability from the point of view of the electronics used for nuclear reactor control will be dealt with: sale and unsafe failures; probability of survival (in the case of reactor safety); availability. The general diagrams of the safety assemblies which have been drawn up for two types of reactor (power reactor and low power experimental reactor) are given. Results are presented of reliability analysis which could be applied to the use of functional modular elements, developed industrially in France. Improvement of this reliability appears to be fairly limited by an increase in the redundancy; on the other hand it is shown how it may be very markedly improved by the use of automatic tests with different frequencies for detecting unsafe failures rates of measurements for the sub-assemblies and for the logic sub-assemblies. Finally examples are given to show the incidence of the complexity and of the use of different technologies in reactor safety equipment on the reliability. (authors) [French] On rappelle les circonstances qui favorisent au C.E.A. la collecte d'une information valable des resultats de la maintenance.

    Full Text Available On ne peut pas demander à un livret l’opéra de reproduire exactement le texte de l’ouvrage dont il s’inspire. Les prétendues « faiblesses » des livrets se justifient par le fait qu’ils n’existent que pour être mis en musique. Dans quelques rares cas où le livret suit à la lettre le texte d’origine (Francis Poulenc, Dialogues des Carmélites, la musique suit le contour des mots, mais, d’ordinaire, la musique pallie le manque de poéticité des livrets. Cela paraît particulièrement le cas dans les opéras du XIXe siècle. En conséquence, il semble impossible de parler des livrets sans prendre la musique en considération. Dans le cas d’Hamlet, comment les librettistes ont-ils abordé le texte ? Où peut-on retrouver la tragédie de Shakespeare dans l’opéra d’Ambroise Thomas ? Quelle lumière l’opéra apporte-t-il sur la réception de Shakespeare au XIXe siècle ? Voilà quelques questions auxquelles cet article tentera de répondre.An opera libretto cannot be expected to reproduce the exact text of the literary or dramatic work on which it is based. The so-called “weaknesses” of the libretti may be accounted for by the fact that they are meant to be set to music. In some rare cases, where the libretto uses part of the original text (like Francis Poulenc’s Dialogues des Carmélites, the music closely follows the shape of the words, but usually it fulfills a poetical aspect lacking in the text. This seems particularly true when we consider 19th century opera. This implies that it is impossible to deal with the libretti without taking the music into account. In the case of Hamlet, what is the librettists’ approach? Where is Shakespeare’s tragedy to be found in Ambroise Thomas’s opera? What light does the opera shed on the reception of Shakespeare in the 19th century? These are the questions this article tries to answer.

    General recommendations for a reference case for economic studies in rheumatic diseases were published in 2002 in an initiative to improve the comparability of cost-effectiveness studies in the field. Since then, economic evaluations in osteoarthritis (OA) continue to show considerable heterogeneity in methodological approach. To develop a reference case specific for economic studies in OA, including the standard optimal care, with which to judge new pharmacologic and non-pharmacologic interventions. Four subgroups of an ESCEO expert working group on economic assessments (13 experts representing diverse aspects of clinical research and/or economic evaluations) were charged with producing lists of recommendations that would potentially improve the comparability of economic analyses in OA: outcome measures, comparators, costs and methodology. These proposals were discussed and refined during a face-to-face meeting in 2013. They are presented here in the format of the recommendations of the recently published Consolidated Health Economic Evaluation Reporting Standards (CHEERS) statement, so that an initiative on economic analysis methodology might be consolidated with an initiative on reporting standards. Overall, three distinct reference cases are proposed, one for each hand, knee and hip OA; with diagnostic variations in the first two, giving rise to different treatment options: interphalangeal or thumb-based disease for hand OA and the presence or absence of joint malalignment for knee OA. A set of management strategies is proposed, which should be further evaluated to help establish a consensus on the "standard optimal care" in each proposed reference case. The recommendations on outcome measures, cost itemisation and methodological approaches are also provided. The ESCEO group proposes a set of disease-specific recommendations on the conduct and reporting of economic evaluations in OA that could help the standardisation and comparability of studies that evaluate

Il est base sur la discretisation du serpentin en volumes de controle, est entierement automatise et peut traiter des echangeurs de chaleur avec des circuits de refrigerant complexes pouvant avoir des entrees et sorties multiples ainsi que des bifurcations. La presence simultanee des trois phases thermodynamiques du refrigerant (liquide sous refroidi, fluide sature, vapeur surchauffee) dans le serpentin est aussi prise en charge. Le modele a ete valide pour un fonctionnement avec et sans formation de givre en utilisant des donnees experimentales disponibles dans la litterature et celles obtenues sur le banc d'essai de CanmetENERGIE. Celui-ci a ete mis a jour pour les besoins de la presente recherche et pour cela, un systeme de surchauffe et d'injection de la vapeur d'eau dans une enceinte a tres basse temperature a ete dimensionne, fabrique et installe. Un dispositif de visualisation de la formation de givre, ainsi qu'un equipement de mesure de la temperature, de la pression et de l'humidite relative de l'air ont aussi ete ajoutes. Une fois le modele valide, des simulations numeriques sur le serpentin avec et sans formation de givre ont ete effectuees. Un premier cas de base a servi comme reference pour d'autres cas pour lesquels une etude parametrique sur la geometrie et le fonctionnement a ete menee. Il a ete montre par rapport au cas de base que : 1. la diminution de la densite des ailettes sur des rangees specifiques du serpentin donne une surface minimale (Amin) plus grande, retardant ainsi l'obstruction totale du serpentin par le givre et permet donc un temps de fonctionnement plus grand et une frequence de degivrage plus faible. 2. une bonne configuration de circuit de refrigerant augmente le temps de fonctionnement du serpentin de 200 % et delivre une puissance

    The main part of the work carried out in the field of ceramic fuels by the Commissariat a l'Energie Atomique during recent years, has been in the direction of uranium dioxide and the uranium-carbon alloys. Uranium dioxide is being studied with the aim of using it as a fuel in the first core of EL-4, in which an integrated thermal conductivity of 29 W/cm is expected at the hottest point for a surface temperature of about 750 C. We concentrated on developing a process for preparing a dioxide powder of suitable characteristics and for sintering this powder, and on evaluating the main properties of the material obtained in the light of the conditions under which they will be used - micro-structural aspect and pore distribution, - mechanical and thermal behaviour in cylindrical form, - control of excess oxygen in the industrial products, - behaviour of the gaseous fission products at high temperatures after or during the course of irradiation. Our aim in the case of uranium carbides has been to determine the conditions of industrial manufacturing of a suitable fuel with a composition close to This has led us to undertake a number of fundamental investigations into - the domain of existence of non-stoichiometric UC, - the influence of elements of O and N on the properties of the UC in which they are dissolved, - the compatibility of uranium-carbon alloys with the different metallic or ceramic materials used for the sheath, - the corrosion of uranium-carbon alloys by H{sub 2}O and CO{sub 2}, - methods of preparing high purity samples, - in-pile irradiation devices for the investigation of these materials in the region of possible operating temperatures. In parallel with these fundamental investigations, we have attempted to define a procedure for the fabrication of uranium-carbon alloys of composition very close to UC which would, in its industrial application, lead to better results than the existent methods from the technical or economical points of view (i.e. sintering

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

    Aujourd'hui, les façons de produire, d'organiser, d'évaluer et d'utiliser les savoirs sont en profond débat. De plus en plus, l'Etat, la société civile et l'économie tentent d'influencer les activités des universités et des laboratoires de recherche. Ces développements mettent à l'épreuve tout à la fois les fondements des systèmes d'enseignement supérieur et de recherche, l'autonomie des institutions scientifiques, la définition des frontières des savoirs et l'acceptation des sciences. Dans des contextes suisses et européens, cet ouvrage s'intéresse aux manières dont les sciences et les technologies sont fabriquées, en analysant leurs institutions et les pratiques. A partir d'une approche relationnelle, les sciences et les technologies sont conçues comme des phénomènes profondément sociaux, culturels et politiques. Une telle démarche déstabilise les visions parfois idéalisées et stéréotypées de la construction des savoirs. Des études de cas détaillées décrivent des phénomè...

    Very low permeable argillaceous rocks like Callovo-Oxfordian clay-stones or Vraconian siltstones were chosen to host a research laboratory built to determine the physico-chemical properties of the host formations for a potential underground disposal of radioactive waste. Knowledge and understanding of post-sedimentary modifications are of prime importance for definition of these properties; evaluation and quantification of the post-sedimentary changes represent the aim of this study, focused specifically on the clay material of the sequences. Samples were taken from two drillings (HTM102 and MAR501). In the HTM102 core samples, illite and mixed-layers illite/smectite are the dominant clay components of most clay fractions. Systematic SEM and TEM observations and isotopic K-Ar and Rb-Sr analyses pointed to diagenetic neo-formations of carbonates (calcite, dolomite) and clays. For instance, veils and laths of authigenic clay particles around old detrital ones can distinctly be observed. The epoch, duration and extent of the diagenetic activity(ies) are difficult to evaluate because of an overall detrital contribution even in the finest granulometric fractions. However; analysis of a bentonite layer in the sequence provides a diagenetic reference for the authigenic clay material. Correlation between relative sea level and authigenesis of smectite-rich mineral has been outlined. Chemistry of diagenetic fluids also seems to be reliable with sea level variations. These observations argue in favour of diagenetic activities limited in restricted rock volumes. The case study of MAR501 is close to the HTM102 one: smectite-rich illite/smectite mixed-layers represent the major component of the clay fraction and K-Ar values argue ire the sense of a mixing between detrital and younger clay populations. Diagenetic glauconites in the sequence yield are age close to 93,7 {+-}0,3 Ma for Vraconian level, in agreement with stratigraphical data. The case study of a clay-filled fault

    Full Text Available In most cases, before choosing a dentist and request an appointment, the patient gets informed from relatives, friends, and acquaintances. Nowadays he also has the opportunity to make the choice by consulting websites or Facebook pages of dentists. The trust is outlined prior to the meeting itself, before stepping into the cabinet. For good visibility, for attracting and retaining a greater number of patients, for an effective communication with patients as well as for gaining their trust, many dentists have decided to create their websites so as to present the cabinet and their services on the Internet. Moreover, their mere presence on the Internet gives authority and gives the impression of strong, well-prepared, modern and open personalities. If the speech they build manages to calm the fears and anxieties of the patient, if the tone is warm and close to the patient, if the site is attractive, not only informative, the patient will be convinced of the qualities and competence of the doctor and his team, of the fact that they will benefit of quality treatment in a pleasant and modern environment. We consulted numerous sites from different cultural environments – French, Italian and Romanian and, given the size of this paper, we presented the theme construction of the discourse in three of them, from the perspective of the French School of discourse analysis. In our view, the theme construction gives clues on how the organization shapes its identity, being a collective discursive construction. We examined what information was selected to be presented, the way they are organized and prioritized, the layout, titration, the text – photo / audio-visual documents relation. Each and every time we found the concern to provide information and explanations, the focus on some keywords (quality, accuracy, competence, experience, performance, innovation, the constant presence of the word “smile” in the discourse, an important number of images

  8. Aspects Referring Wind Energy Integration from the Power System Point of View in the Region of Southeast Europe. Study Case of Romania

    Directory of Open Access Journals (Sweden)

    Simona-Vasilica Oprea

    2018-01-01

    Full Text Available Wind energy integration is a complex target that could refer to different aspects such as: grid capacity; power system; support scheme; environmental; social issues; etc. It is probably the less predictable renewable energy sources (RES due to its high volatility being difficult to be securely integrated into the power systems. This paper will focus on the wind energy integration from the power system point of view, emphasizing the case of Romania. Before going into the Romanian case, the paper analyzes the potential benefits of the regional approach in terms of power system integration, revealing that it can bring significant advantages by reducing the required power reserves or increasing wind power plants (WPP generation. Currently, the power system integration is one of the major obstacle to large scale wind energy penetration in the region of Southeast (SE Europe with high wind energy potential. The results of our research consist in proposing a model for estimating the balancing reserves sharing at regional level, comparing regional to country-by-country approach in terms of the power reserve requirements for balancing the operation of WPP. It definitely reveals that by regional Transmission System Operators (TSO coordination; less reserves are needed; therefore, the space for RES enlarges. We also propose a model for Romanian power system that is able to calculate the installed power of WPP that could operate without considerable interruptions. Also, the model estimates the additional power reserves required for larger wind energy integration. This perspective can provide interesting insights on what should be foreseen as reasonable behavior of the policy makers and investors.

    2017-06-01

    Full Text Available Objectives: The present study reports a case of late mandibular fracture due to third molar extraction and highlights the inherent clinical, ethical and legal aspects related to this surgical complication. Material and Methods: A female patient underwent surgical procedure for the extraction of the mandibular right third molar. Two days after the surgery the patient reported pain and altered occlusion in the right side of the mandible. After clinical and radiographic re-examination, the diagnosis of late mandibular fracture was established. A second surgery, under general anaesthesia, was performed for the fixation of the mandibular bone. Results: The fractured parts were reduced and fixed with locking plate systems and 2 mm screws following load-sharing principles. The masticatory function showed optimal performance within 7 and 21 days after the surgery. Complete bone healing was observed within 1 year of follow-up. Conclusions: For satisfactory surgical outcomes, adequate surgical planning and techniques must be performed. Signed informed consents explaining the risks and benefits of the treatment must be used to avoid ethical and legal disputes in dentistry.

    This report outlines the general philosophy of radiation control in French reactors and their annexes. The supervision is carried out continuously from a central control panel on which appear all the measurements made and the alarm signals. The equipment is described; one item makes it possible to measure simultaneously the radioactive dusts and gases. The specifications of the alarm system, which is considered to be the most important are given. Finally a new measuring technique is proposed which makes it possible to reduce considerably the cost of radiation control while at the same time providing the results in a form in which they can be easily treated, in particular in the case of the calculation of total doses. (authors) [French] Ce rapport definit la philosophie generale du controle des radiations dans les piles francaises et dans leurs annexes. La surveillance se fait d'une maniere continue a partir d'un tableau de controle centralise ou sont reportees toutes les mesures et les signalisations d'alarme. On decrit les appareils utilises, dont un permet la mesure simultanee des poussieres et gaz radioactifs, et on definit les specifications de la fonction alarme qui est consideree comme la plus importante. Enfin on propose une nouvelle technique de mesure qui permettrait de reduire considerablement le cout du controle des radiations tout en fournissant des resultats plus facilement exploitables, en particulier pour le calcul des doses integrees.

C’est aussi un des moyens les plus perturbants pour le chercheur, souvent confronté aux interdits de contact entre des groupes dont les intérêts ou les principes de vie sont antagonistes. Établir des relations étroites avec des militants du Front national, certains d’entre eux « néo-nazis », certains vivant à quelques rues de chez soi, tout en étant « homo », avec pour proches amis des hommes de couleur, de plus entouré de personnes hostiles à ce parti, oblige ainsi à gérer des liens inconciliables.

    Écrire l'histoire de l'Univers, tel est l'objectif commun des physiciens des particules et des astrophysiciens. Pour y parvenir, deux approches s'épaulent : la voie de l'infiniment petit, que l'on emprunte via de gigantesques accélérateurs de particules, et celle de l'infiniment grand, dont le laboratoire est l'Univers. Un Univers qui est bien loin d'avoir livré tous ses secrets. On connaît à peine 4,8 % de la matière qui le constitue, le reste étant composé de matière noire (25,8 %) et d'énergie noire (69,4 %), toutes deux de nature inconnue. Et si la récente découverte du boson de Higgs valide le Modèle standard de la physique des particules, celui-ci est toujours incomplet et doit être étendu à ou dépassé. Est-on arrivé au bout du jeu de poupées russes de la matière ? Quelles sont les particules manquantes ? Faut-il revoir les lois fondamentales ? Quels instruments faut-il mettre en œuvre pour accéder à cette « nouvelle physique » ? Comment parler de Super Big Science aux citoye...

    Deep geological formation disposal is the reference solution in France for the management of medium and high activities radioactive waste. In this context, to demonstrate the feasibility of such a disposal, it is necessary to evaluate the long-term performances and the behaviour of the materials engaged in the elaboration of engineered barrier systems (EBS) and waste package elements. The studies mentioned and synthesized in this HDR thesis focused mainly on the convective transport of gas (under pressure gradient) in cementitious matrices, by coupling microstructure aspect (porosity/pores sizes distribution) and hydric environment (water saturation). Works on physico-chemical durability allowed the description of the chemical degradation of cement-based materials in extreme conditions using ammonium nitrate, to increase the materials damaging processes in order to identify functional margins. In relationship with the interim storage management phase, studies related to the behaviour and characterization of concrete submitted to high temperatures (up to 400 C) were also described. Finally, results concerning the gas (H{sub 2}) overpressure resistance of engineered barriers made of compacted clays were summarized. (author)

    Le travail presente ici est un bilan du travaux de recherche effectues sur l'injectabilite des coulis de ciment dans lu milieux fissures. Un certain nombre de coulis a base de ciment Portland et microfin ont ete selectionnes afin de caracteriser leur capacite a penetrer des milieux fissures. Une partie des essais a ete menee en laboratoire. L'etude rheologique des differents melanges a permis de tester l'influence de l'ajout de superplastifiant et/ou de fumee de silice sur la distribution granulometrique des coulis et par consequent sur leur capacite a injecter des colonnes de sable simulant un milieu fissure donne. La classe granulometrique d'un coulis, sa stabilite et sa fluidite sont apparus comme les trois facteurs principaux pour la reussite d'une injection. Un facteur de finesse a ete defini au cours de cette etude: base sur la classe granulometrique du ciment et sa stabilite, il peut entrer dans la formulation theorique du debit d'injection avant application sur chantier. La deuxieme et derniere partie de l'etude presente les resultats de deux projets de recherche sur l'injection realises sur chantier. L'injection de dalles de beton fissurees a permis le suivi de l'evolution des pressions avec la distance au point d'injection. L'injection de murs de maconnerie a caractere historique a montre l'importance de la definition de criteres de performance des coulis a utiliser pour traiter un milieu donne et pour un objectif donne. Plusieurs melanges peuvent ainsi etre predefinis et mis a disposition sur le chantier. La complementarite des ciments traditionnels et des ciments microfins devient alors un atout important. Le choix d'utilisation de ces melanges est fonction du terrain rencontre. En conclusion, cette recherche etablit une methodologie pour la selection des coulis a base de ciment et des pressions d'injection en fonction de l'ouverture des fissures ou joints de construction.

    The diagnostic tools and possible treatments are shown with the example of the three cases. The radiologic interventions may, in some cases, avoid surgery, but their potentials are restricted by a couple of conditions such as localisation of the lesions near to the hilus, multiple abscesses, ropy pus, or fistulae. Therefore, splenectomy continues to be the golden standard. Given adequately fast diagnosis and therapy, lethality can be reduced today to less than 10 %.

  6. 15-year follow-up of a case of amelogenesis imperfecta: importance of psychological aspect and impact on quality of life.

    Amelogenesis imperfecta (AI) represents a group of hereditary conditions which affects enamel formation in the primary and permanent dentitions. Gene mutations alter the quality and/or quantity of enamel. AI often has severe consequences for the patient such as high tooth sensitivity, low aesthetic quality of the dentition, and poor mechanical properties of the dental tissues. This can result in reduced oral health-related quality of life. We present the case of a child affected by AI which had been diagnosed at the age of 9 years. Teeth presented many enamel defects. The patient presented thin brown to yellow enamel and the surface was rough and granular. He revealed short clinical crowns, occlusal wear with exposed dentine in posterior areas. He also presented a lateral open bite and lingual lateral interposition due to partial destruction of deciduous molars. Panoramic radiograph showed no differences between enamel and dentine appearance and also coronary destruction of permanent molars. The initial treatment consisted of adaptation of composite resins on permanent incisors to improve aesthetics. Preformed metal crowns were placed on first permanent molars to prevent their premature destruction. This was disrupted for a variety of reasons. Fourteen years later, after a dental nomadism, the patient consulted by chance a dentist who identified his genetic pathology and was aware of its consequences. Extensive prosthodontic treatment was needed, but oral hygiene was poor and gingivitis remained. Dealing with high loss of motivation has been one of the main challenges because this patient had a lot of psychological problems. He was concerned, as are many patients affected by AI or other enamel abnormalities. This paper highlights the difficulties of long-term care of this dental abnormality. Psychological aspects of the quality of life, which is a common feature in patients suffering from many kinds of enamel anomalies, are very important.

    Full Text Available Every neutron scattering experiment requires the choice of a suited neutron diffractometer (or spectrometer in the case of inelastic scattering with its optimal configuration in order to accomplish the experimental tasks in the most successful way. Most generally, the compromise between the incident neutron flux and the instrumental resolution has to be considered, which is depending on a number of optical devices which are positioned in the neutron beam path. In this chapter the basic instrumental principles of neutron diffraction will be explained. Examples of different types of experiments and their respective expectable results will be shown. Furthermore, the production and use of polarized neutrons will be stressed.

  11. DES Science Portal: Computing Photometric Redshifts

    Energy Technology Data Exchange (ETDEWEB)

    Gschwend, Julia [LIneA, Rio de Janeiro

    2016-01-01

    An important challenge facing photometric surveys for cosmological purposes, such as the Dark Energy Survey (DES), is the need to produce reliable photometric redshifts (photo-z). The choice of adequate algorithms and configurations and the maintenance of an up-to-date spectroscopic database to build training sets, for example, are challenging tasks when dealing with large amounts of data that are regularly updated and constantly growing. In this paper, we present the first of a series of tools developed by DES, provided as part of the DES Science Portal, an integrated web-based data portal developed to facilitate the scientific analysis of the data, while ensuring the reproducibility of the analysis. We present the DES Science Portal photometric redshift tools, starting from the creation of a spectroscopic sample to training the neural network photo-z codes, to the final estimation of photo-zs for a large photometric catalog. We illustrate this operation by calculating well calibrated photo-zs for a galaxy sample extracted from the DES first year (Y1A1) data. The series of processes mentioned above is run entirely within the Portal environment, which automatically produces validation metrics, and maintains the provenance between the different steps. This system allows us to fine tune the many steps involved in the process of calculating photo-zs, making sure that we do not lose the information on the configurations and inputs of the previous processes. By matching the DES Y1A1 photometry to a spectroscopic sample, we define different training sets that we use to feed the photo-z algorithms already installed at the Portal. Finally, we validate the results under several conditions, including the case of a sample limited to i<22.5 with the color properties close to the full DES Y1A1 photometric data. This way we compare the performance of multiple methods and training configurations. The infrastructure presented here is an effcient way to test several methods of

    Between 1977 and 1979, important civil engineering works were made on the moraine of "Col des Gentianes", which is situated 2894 meters above the sea level in the region of Mt-Fort, Valais, Switzerland. Two cableway station arrivals, a departure station to the Mt-Fort and a restaurant were built on. This moraine was formed during the last advance of the Tortin glacier during the Little Ice Age. Since 1980, the glacier has melted dramatically and the moraine is creeping. The moraine in front of the cableway departure station to the Mt-Fort sagged by 2 to 4 meters in 30 years. A large volume of ice is still present within the moraine and melting of the ice would make its stability even more precarious. Since 2007 the moraine is monitored by terrestrial laser scanning (TLS). Two TLS campaigns were made in July and October 2008 and compared to datasets acquired in 2007. The comparison of sequential TLS point clouds enabled the detection and quantification of movements in the moraine: (1) by computing oblique (shortest) or vertical differences, (2) by creating displacement vectors and (3) by profiles across the TLS point clouds. Between July and October 2008 the Tortin glacier melted by 1 to 2.5 m and the moraine creeped in direction of the glacier by 0.25 to 0.75 m. During the same period, a landslide zone has been clearly identified downslope of the cableway departure station to the Mt-Fort. Important movements between 1.5 to 5 meters were measured on this landslide through the creation of displacement vectors. This landslide scarp is delimited by 0.5 and 1 meter downward displacements in two month. Already in 2007, a less important landslide was identified and some ice had been observed in the scarp zone. The TLS permitted to analyze the distribution of these movements on the entire moraine and not only on few measurement points like given by D-GPS. The computed TLS displacement vectors are in good agreement with annual D-GPS measurements performed on this moraine

    The question of safety in regard to criticality accident risks has two aspects: prevention of the cause and limitation of the consequences. These two aspects are closely connected. The effort devoted to prevention of the causes depends on the seriousness of the possible human psychologic and economic consequences of the accident. The criticality accidents which have occurred in the nuclear industry, though few in number, do reveal the imperfect nature of the techniques adopted to prevent the causes, and also constitute the only available realistic basis for evaluating the consequences and developing measures to limit them. The authors give a analysis of the known causes and consequences of past criticality accidents and on this basis make a number of comments concerning: the validity of traditional safety criteria, the probability of accidents for different types of operations, characteristic accidents which can serve as models, and the extent of possible radiological consequences. The measures adopted in France to limit the consequences of a possible criticality accident under the headings: location, design and lay-out of the installations, accident detection, and dosimetry for the exposed personnel, are briefly described after a short account of the criteria used in deciding on them.

    The paper summarizes the main policies adopted for the management of fission product effluents and briefly describes the essential technical features of the stainless steel storage installations (in acid medium) used in France, giving a breakdown of the costs involved. The dependence of these costs on the activity of the solutions stored and on their heat release is shown. The second part of the paper discusses the cost of storage in terms of feasible tank size. The optimum size for such tanks and the rate at which they are placed in service are determined in relation to the characteristics of the fission products to be stored and to the respective capacities of the installations for processing irradiated natural uranium. It is shown that although storage costs depend on the assumptions made regarding the useful life of installations, rates of interest and operating costs, optimum policy decisions (as to size and rate of entry into service) are independent of these assumptions, being determined solely by the variation in the cost of tanks, according to size. These are the factors which enter into the optimized cost of storing these effluents indefinitely. In the third part, this method of indefinite storage is compared with other possibilities of fission product management, e.g. vitrification and separation of Cs and Sr. The paper discusses the economics of the various methods and summarizes some possible long-term solutions.

    Full Text Available Die häufigste mykotische Infektion des Penis stellt die Balanitis/Balonoposthitis durch Candida albicans dar. Sie weist eine steigende Inzidenz auf und scheint vornehmlich durch Genitalverkehr übertragen zu werden. Penile Infektionen durch Dermatophyten sind sehr selten, obwohl die Tinea inguinalis zu den häufigeren Erkrankungen zählt. Eine Mitbeteiligung des Penis im Rahmen von Systemmykosen kennzeichnet zumeist ein schwer verlaufende Erkrankung. Ursächlich kann beim immunoinkompetenten Patienten nahezu jeder Erreger in Frage kommen. Biopsie sowie Gewebekultur aus den meist ulzerativen Veränderungen können die Diagnose sichern. Die meisten superfiziellen Infektionen sprechen zufriedenstellend auf eine topische antimykotische Behandlung an, insbesondere wenn Provokationsfaktoren und die Möglichkeit der sexuellen Transmission berücksichtigt werden. Ausgedehnte Infektionen durch Dermatophyten, Hefen und natürlich systemische Infektionen erfordern eine systemische antimykotische Therapie.

    Die Organtransplantation stellt eine verbreitete Therapie dar, um bei krankheitsoder unfallbedingter Schädigung eines Organs die Gesamtheit seiner Funktionen wieder herzustellen, indem es durch ein Spenderorgan ersetzt wird. Organtransplantationen werden für die Leber, die Niere, die Lunge, das Herz oder bei schweren grossflächigen Verbrennungen der Haut vorgenommen. Der grosse apparative, personelle und logistische Aufwand und die Risiken der Transplantationschirurgie (Abstossungsreaktionen) sowie die mangelnde Verfügbarkeit von immunologisch kompatiblen Spenderorganen führen jedoch dazu, dass der Bedarf an Organtransplantaten nur zu einem sehr geringen Teil gedeckt werden kann. Sind Spenderorgane nicht verfügbar, können in einzelnen Fällen lebenswichtige Teilfunktionen, wie beispielsweise die Filtrationsfunktion der Niere durch die Blutreinigung mittels Dialyse ersetzt oder, bei mangelnder Funktion der Bauchspeicheldrüse (Diabetes), durch die Verabreichung von Insulin ein normaler Zustand des Gesamtorganismus auch über Jahre hinweg erhalten werden. Bei der notwendigen lebenslangen Anwendung apparativer oder medikamentöser Therapie können für den Patienten jedoch häufig schwerwiegende, möglicherweise lebensverkürzende Nebenwirkungen entstehen. Daher werden in der Forschung Alternativen gesucht, um die Funktionen des ausgefallenen Organs durch die Implantation von Zellen oder in vitro gezüchteten Geweben möglichst umfassend wieder herzustellen. Dies erfordert biologisch aktive Implantate, welche die für den Stoffwechsel des Organs wichtigen Zellen enthalten und einen organtypischen Stoffwechsel entfalten.

    This article presents the system of compensation for damages in case of a nuclear accident. This system of civil liability for nuclear damage, as a specific regime, departs on several points from the common rules of civil liability, in order to provide an adequate and equitable compensation for the damages suffered by the victims of nuclear accidents. The French system of civil liability for nuclear damage results from two International Conventions integrated in French law (Paris convention 1960 and Brussels convention 1963) and the French law of 1968, October 30 on civil liability in the area of nuclear energy. These texts define the conditions under which a nuclear operator could be held liable in case of a nuclear accident. The protocols to amend the Paris and Brussels Conventions of 2004, not yet come into force, are also presented. They ensure that increased resources are available to compensate a greater number of victims of a nuclear accident. (author)

(author) [French] La construction des reacteurs G2 et G3, dans le cadre du premier plan quinquennal francais, a ete confiee par le C.E.A. au groupement d'industriels FRANCE-ATOME. Bien que ces reacteurs restent essentiellement plutonigenes, on a accole a chacun d'eux une centrale electrique devant fournir 40 MW, dont la responsabilite a ete assumee par l'E.D.F. Le coeur du reacteur adopte la plupart des solutions du reacteur G1 (excepte la fente centrale): canaux horizontaux, empilement de briques parallelepipediques de graphite, protection thermique en acier. Le refroidissement est assure par du gaz carbonique sous 15 atmospheres. Cette pression est tenue par un caisson en beton precontraint, ayant la forme d'un cylindre horizontal. Des cables d'acier sous tension entourent le cylindre de beton, dont ils sont isoles par des patins. Les fonds du cylindre ont pose des problemes particuliers qui ont conduit a la forme hemispherique adoptee. L'etancheite du caisson est assuree par une tole de 30 mm liee a la face interne du beton. Un des aspects les plus originaux de ces reacteurs est la possibilite de charger et decharger en marche. Cote chargement, des sas a barillets, pesant chacun 50 tonnes; permettent de faire passer les cartouches neuves sous la pression de 15 atmospheres. Ces cartouches progressent de facon quasi continue dans le canal pour tomber finalement par des goulottes inclinees et des toboggans helicoidaux dans un nouveau sas. La circulation du gaz carbonique est assuree par trois turbo-soufflantes, actionnees elles-memes par la vapeur moyenne pression obtenue dans echangeurs, chaque reacteur alimente quatre echangeurs ayant pose de difficiles problemes de construction et de mise en place.

    hearing assessments of a case of Crouzon syndrome at the age 6:4 years. PROCEDURE: the subject carried out the following evaluations: ABFW, Test of Receptive Vocabulary, Language-Cognition Development Evaluation, Evaluation of Structures and Functions of the Stomatognathic System, pure-tone audiometry threshold, immitance measures and vocal audiometry. RESULTS: the pure-tone audiometry identified bilateral moderate conductive hearing loss, compatible with vocal audiometry's and immitance measures' results. The stomatognathic system evaluation showed that the structures had reduced tonus and altered posture and mobility. Suction, chewing, deglutition and breathing functions were also altered. Phonologically, the following processes were identified: Cluster Simplification, Stopping of Fricatives and Others. In the Fluency evaluation, subject's performance was below the expected scores for matched age and gender. In the Pragmatics test, the child had 14.4 acts per minute and, predominantly, gestural communication. The Receptive Vocabulary Test showed scores 7.1% below reference. In the Expressive Vocabulary Test, data indicated a performance compatible to the reference values of 4 and 5 year-old children, below the expected scores for the subject's age. Regarding language and cognition, the analysis indicated a gap between the child's performance and the developmental level. CONCLUSION: the deficits caused by the syndrome are diffuse and interconnected. The present study had the aim to present the Speech-Language and Hearing Pathology associated aspects of a Crouzon syndrome case and to provide initial data to further investigate these aspects and the intervention process.

    The authors discuss the difficulties encountered in the exploration of a typical deposit in the Nord-Limousin, using the resistivity measurement method. In the zone in question the over-thrust was very variable and difficult to predict. The uraniferous deposits had two types of aspect, the passage from one to the other being often very sudden: long thin veins without gangue; short and thick lens-shape deposits which were strongly contaminated by clay towards their edges. After several unsatisfactory attempts, the device known as the 'rectangular map' was adopted and gave an acceptable structural representation rapidly and cheaply. For the placing of the probes however, methods are required which are more refined and sensitive. It is in any case useless to expect to obtain a satisfactory representation and a sufficient accuracy using a single technique; especially in the region under consideration. (author) [French] Les auteurs exposent les difficultes rencontrees pour l'exploration, par la methode des mesures de resistivite, d'un gisement type du Nord-Limousin: il s'agissait d'une zone a recouvrement tres variable et difficilement previsible. Les occurences uraniferes y affectaient deux facies passant brutalement de l'un a l'autre: longs filonnets minces et sans gangue; lentilles courtes et puissantes avec alteration argileuses tres etendue aux epontes. Apres plusieurs essais peu satisfaisants, le dispositif dit 'carte des rectangles' a ete adopte pour obtenir rapidement et a bon compte un schema structural suffisant. Mais des methodes plus fines et plus sensibles sont necessaires pour guider l'implantation des sondages. Il est d'ailleurs vain d'esperer trouver a la fois la representativite d'ensemble et la precision, dans l'utilisation d'une seule technique, surtout dans la region envisagee. (auteur)

Chemical aspects of incinerating highly chlorinated and actinide {alpha} contaminated organic waste: application to the Iris process; Aspects chimiques de l'incineration des dechets organiques fortement charges en chlore et contamines en actinides emetteurs {alpha}.

    A fraction of the waste produced by nuclear activities is combustible, and thus suitable for incineration to produce gases, ash and fines. A typical composition representative of actual organic waste mixtures was defined for the purpose of investigating possible heat treatment processes; the composition is identified according to components Table 1 and elements Table II. The high polyvinyl chloride (PVC) content is responsible for the high chlorine potential in the process equipment. The quantity and quality of the resulting solid residue depends entirely on the inorganic load of the organic waste, whose behavior is entirely conditioned by the process conditions. For example, pure polyethylene is totally converted to gases (water and carbon dioxide), while the composition shown in Table II produces a range of oxides and chlorides. The high chlorine content results in partial chlorination of the inorganic compounds, but can also lead to interactions with the process equipment. The temperature dependent variation of the chlorination equilibrium constants of various metals clearly shows that all the elements of technological alloys may be subject to active corrosion by hydrochloric acid. However, the corresponding oxides-notably alumina-are much less sensitive to corrosion; aluminum-based alloys are therefore preferred for incinerator construction and to limit corrosion by hydrochloric acid. Thermodynamic and kinetic studies led to the development of the IRIS three-step process. Gas emissions occurring during processing of solid materials are completely oxidized in the after-burning step at 1100 deg C, and are then ducted to a HERA filtration system capable of retaining all the actinide {alpha} radionuclides. Although corrosion-related problems are attenuated in the two-step process chlorine can combine with the inorganic waste material to form chlorides with potentially damaging effects on the system; this is the case for zinc chloride and for volatile chlorides in

    Hypoproteinaemia both human and experimental has been studied with the help of nuclear labelling. A comparative study has been made of the fate of serum proteins labelled by an endogenous path after administration of nitrogen-15 glycine and also of serum albumin labelled by exogenous path using iodine-131. We have determined the biological period of the serum albumin and serum globulins and also the magnitude of the vascular and extravascular pools of serum albumin. In this way it has been possible to measure the speed of replacement of plasma proteins. A presentation of results taken from both clinical observation and experiment leads to a discussion on the pathogenic mechanism of hypoproteinaemia.

    Full Text Available Abstract The genitive singular of the weak masculine nouns appears in three non-standard variations in addition to the standard suffix -(en: one variation is case augmenting (des Bär-en-s, one is stem affixing (des Polizist-s and one lacks a case suffix (des Patient-Ø. Linguists as well as language critics have focussed mainly on the stem affixing genitive while more or less ignor­ing the two other non-standard variations. This paper presents a corpus-based investigation regarding frequency and contexts of all three variations, also considering the diachronic back­ground and the implications the results might have for predicting the further development of the declension class of the weak masculine nouns.

    Full Text Available L’alimentation des sans-logis est analysable, à partir du terrain, selon deux versants, parfois utilisés conjointement, qui sont celui de leur autonomie et/ou celui de leur dépendance envers le don alimentaire. Dans ce dernier cas, les contenus comme les formes témoignent trop souvent d’une impossibilité d’assurer l’équilibre nutritionnel de ces mangeurs et le respect des multiples aspects socialisants compris dans l’acte alimentaire. Le choix d’un traitement social dans l’ « urgence » et par l’humanitaire, tout en maintenant de manière chronique cette population à la rue, montre ainsi ses limites et les palliatifs tragiques qu’il implique tant dans l’alimentation que dans le reste des solutions qu’il propose depuis plus de vingt ans.The diet of the homeless can be looked at from two joint perspectives, both based on fieldwork : their autonomy and their dependency on food donations. In the latter case, the contents as well as the form of the donation all too often point at the impossibility of ensuring a nutritionally balanced donation and respecting the multiple social conventions linked to the act of eating. In resorting to such ‘emergency’ humanitarian relief, we maintain the chronicity of homelessness while also revealing the limits of such relief and the tragic palliatives implied, both in terms of diet and other solutions suggested over the past fifteen years.

    The increase of bundle supply has become widespread in several sectors (for instance in telecommunications and energy fields). This paper review relates strategic aspects of bundling. The main purpose of this paper is to analyze profitability of bundling strategies according to the degree of competition and the characteristics of goods. Moreover, bundling can be used as price discrimination tool, screening device or entry barriers. In monopoly case bundling strategy is efficient to sort consumers in different categories in order to capture a maximum of surplus. However, when competition increases, the profitability on bundling strategies depends on correlation of consumers' reservations values. (author)

  18. How to model different socio-economic and environmental aspects of biomass utilisation: Case study in selected regions in Slovenia and Croatia

    International Nuclear Information System (INIS)

    Krajnc, N.; Domac, J.

    2007-01-01

    Wood biomass is an important renewable source of energy, especially in countries with traditional dependency on forestry resources. In these countries, wood biomass can have numerous positive socio-economical and environmental effects. This paper presents a new model (SCORE model) for estimation of 15 socio-economic and environmental aspects of increased use of biomass from the forests. The presented model enables selected estimation of different aspects in the whole chain of biomass production, preparation and use. Namely, the model enables the estimation of net labour income, net profit, regional public finance income, net direct jobs, net indirect jobs, net induced jobs, total net jobs, contribution to forest management, impact on wood waste utilisation, impact on other woody biomass utilisation, avoided costs of landfill, saving CO 2 emissions, possible impact on regional unemployment, avoided costs of unemployment, additional jobs for farmers, additional activities on farms (from indirect and induced jobs) and self-sufficiency in electricity production. The SCORE model was tested in selected regions in Slovenia and Croatia and apart from a good understanding of the socio-economic and environmental aspects, it also enables an overview of the economy of wood biomass production, given that it includes the economic analysis of wood biomass production and use. The model is not intended for a detailed economic analysis of separate phases of wood biomass production, processing and use, but particularly to show advantages or disadvantages that can result from planned and existing biomass systems.

    , but we can never be sure that the numerical results given by any of these software packages are applicable to a practical industrial case, without checking these results in one way or another. There is quite general agreement on the necessity of obtaining experimental data concerning problem examples, in order to check and compare the computation results of the various software packages proposed for dealing with these specific problems. On the experimental side, there are a great deal of measurement methods able to give local values of temperature, pressure, velocities, concentrations of chemical species, phases ratio, size of bubbles, drops or particles, as well as to produce an overall visualization of flows. We have mentioned the difficulties linked to the mathematical treatment of the equations written for simulating reactive flows. As usually done in CFD, for most problems encountered, a first useful solution can be obtained by limitingthe modelto oneortwospace dimensions (1D or 2D. However, very often it will be necessary not only to solve the 3D simulation set of equations, but also to achieve the unstationary solution of the same equations in order to really represent the true behaviour of the physical system. This last objective means much more complicated research, especially from the mathematical point of view.

    This work presents an application of Failure Mode Effect Analysis (FMEA) to the process of identification of environmental aspects and impacts as a part of implementation and maintenance of an Environmental Management System (EMS) in accordance with the ISO 14001 standard. Also, it can contribute, as a complement, to the evaluation and improvement of safety of the installation focused. The study was applied to the Nuclear Fuel Center (CCN) of Nuclear and Energy Research Institute (IPEN), situated at the Campus of University of Sao Paulo, Brazil. The CCN facility has the objective of promoting scientific research and of producing nuclear fuel elements for the IEA-R1 Research Reactor. To identify the environmental aspects of the facility activities, products, and services, a systematic data collection was carried out by means of personal interviews, documents, reports and operation data records consulting. Furthermore, the processes and their interactions, failure modes, besides their causes and effects to the environment, were identified. As a result of a careful evaluation of these causes it was possible to identify and to classify the major potential environmental impacts, in order to set up and put in practice an Environmental Control Plan for the installation under study. The results have demonstrated the validity of the FMEA application to nuclear facility processes, identifying environmental aspects and impacts, whose controls are critical to achieve compliance with the environmental requirements of the Integrated Management System of IPEN. It was demonstrated that the methodology used in this work is a powerful management tool for resolving issues related to the conformity with applicable regulatory and legal requirements of the Brazilian Nuclear Energy Commission (CNEN) and the Brazilian Institute of Environment (IBAMA).

    The epidemiological evidence suggests that individuals with higher education level have a reduced risk of developing dementia. Because cognitive reserve and its compensation mechanisms may modulate the clinical expression in neuro-degenerative pathology, it is important to study subjects who present mild cognitive disturbance with functional imaging. The cerebral SPECT has been used to determine regional uptake of radiotracer into the brain of patients with cognitive impairment. These abnormalities of blood flow were correlated with cognitive impairment. The cerebral SPECT is also useful to investigate preclinical dementia and to predict the evolution of cognitive disturbance. This article, reports some technical and semeiological notions and illustrate with five clinical cases the scintigraphic aspect of some dementia syndrome. (authors)

    Pancreatic neuroendocrine neoplasms (NEN) account for 1-2 % of all pancreatic neoplasms and represent a rare differential diagnosis. While some pancreatic NEN are hormonally active and exhibit endocrine activity associated with characteristic symptoms, the majority are hormonally inactive. Imaging techniques such as ultrasound, computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET) or as combined PET/CT play a crucial role in the initial diagnosis, therapy planning and control. Endoscopic ultrasound (EUS) and multiphase CT represent the reference methods for localization of the primary pancreatic tumor. Particularly in the evaluation of small liver lesions MRI is the method of choice. Somatostatin receptor scintigraphy and somatostatin receptor PET/CT are of particular value for whole body staging and special aspects of further therapy planning. (orig.) [German] Neuroendokrine Neoplasien (NEN) des Pankreas stellen mit einem Anteil von 1-2 % aller pankreatischen Tumoren eine seltene Differenzialdiagnose dar. Ein Teil der Tumoren ist hormonell aktiv und faellt klinisch durch charakteristische Symptome auf, wohingegen der ueberwiegende Anteil hormonell inaktiv ist. Bildgebende Verfahren wie Sonographie, Computertomographie (CT), Magnetresonanztomographie (MRT) und nicht zuletzt Positronenemissionstomographie (PET oder kombiniert als PET/CT) spielen eine zentrale Rolle fuer Erstdiagnose, Therapieplanung und -kontrolle. Die Endosonographie und die multiphasische CT stellen die Referenzmethoden zur Lokalisation des Primaertumors dar. Fuer die Differenzierung insbesondere kleiner Leberlaesionen bietet die MRT die hoechste Aussagekraft. Fuer das Ganzkoerperstaging und bestimmte Aspekte der Therapieplanung lassen sich die Somatostatinrezeptorszintigraphie und v. a. die Somatostatinrezeptor-PET/CT heranziehen. (orig.)

Hazards when the reactor is normally operating: {gamma} radiation from hot uranium or air contamination by fission gases, {gamma} radiation or contamination by the coolant (air, nitrogen, heavy-water), {gamma} radiation from radioisotopes. Hazards in the case of an accident: presence of hot uranium in the atmosphere, soil contamination.

    Directory of Open Access Journals (Sweden)

    Monika Ćwiklińska

    2015-08-01

    Full Text Available Introduction: The available legal regulations in Poland do not define the concentration thresholds enabling to differentiate between the states of “after-use” versus “under the influence” of a drug, as it is in the case of alcohol. The aim of the study was to analyse jurisdiction in cases regarding the evaluation of the effects of intoxicating agents and ethanol-like intoxicants and to identify ambiguities and gaps in the applicable regulations leading to problems in preparing expert opinions. Material and methods: The material included the opinions of experts in the field of toxicology and forensic medicine made by the Department of Forensic Medicine in Lublin in the years 2009–2011 and records obtained in the process of inquiry from the regional prosecutor’s offices and courts in 52 cases. Results : Amongst 52 cases in which the ordered toxicology examinations demonstrated the presence of intoxicating agents in drivers’ blood (tetrahydrocannabinols in 39 and amphetamine in 21 cases in 2 cases petty offence proceedings were instituted (Art. 87 of the Petty Offence Code although high concentrations of xenobiotics indicated the state of being “under the influence” of a narcotic drug (Art. 178a of the Penal Code. Three cases were discontinued despite expert opinions that the drivers were at least in the after-narcotic use state. In only 3 cases were witnesses asked to provide testimony about the circumstances of the driver’s conduct. Conclusions : The analysis has demonstrated that judicial bodies expect forensic expertise based exclusively on toxicological examination results; when expert findings are inconclusive, they only administer litigations opportunistically applying the principle of the presumption of innocence understood literally. Considering the above, threshold values of “use” and “influence” of the most commonly detected drugs should be urgently determined.

  20. When to use discrete event simulation (DES) for the economic evaluation of health technologies? A review and critique of the costs and benefits of DES.

    Science.gov (United States)

    Karnon, Jonathan; Haji Ali Afzali, Hossein

    2014-06-01

    Modelling in economic evaluation is an unavoidable fact of life. Cohort-based state transition models are most common, though discrete event simulation (DES) is increasingly being used to implement more complex model structures. The benefits of DES relate to the greater flexibility around the implementation and population of complex models, which may provide more accurate or valid estimates of the incremental costs and benefits of alternative health technologies. The costs of DES relate to the time and expertise required to implement and review complex models, when perhaps a simpler model would suffice. The costs are not borne solely by the analyst, but also by reviewers. In particular, modelled economic evaluations are often submitted to support reimbursement decisions for new technologies, for which detailed model reviews are generally undertaken on behalf of the funding body. This paper reports the results from a review of published DES-based economic evaluations. Factors underlying the use of DES were defined, and the characteristics of applied models were considered, to inform options for assessing the potential benefits of DES in relation to each factor. Four broad factors underlying the use of DES were identified: baseline heterogeneity, continuous disease markers, time varying event rates, and the influence of prior events on subsequent event rates. If relevant, individual-level data are available, representation of the four factors is likely to improve model validity, and it is possible to assess the importance of their representation in individual cases. A thorough model performance evaluation is required to overcome the costs of DES from the users' perspective, but few of the reviewed DES models reported such a process. More generally, further direct, empirical comparisons of complex models with simpler models would better inform the benefits of DES to implement more complex models, and the circumstances in which such benefits are most likely.

  5. Vecteurs Singuliers des Theories des Champs Conformes Minimales

    Science.gov (United States)

    Benoit, Louis

    En 1984 Belavin, Polyakov et Zamolodchikov revolutionnent la theorie des champs en explicitant une nouvelle gamme de theories, les theories quantiques des champs bidimensionnelles invariantes sous les transformations conformes. L'algebre des transformations conformes de l'espace-temps presente une caracteristique remarquable: en deux dimensions elle possede un nombre infini de generateurs. Cette propriete impose de telles conditions aux fonctions de correlations qu'il est possible de les evaluer sans aucune approximation. Les champs des theories conformes appartiennent a des representations de plus haut poids de l'algebre de Virasoro, une extension centrale de l'algebre conforme du plan. Ces representations sont etiquetees par h, le poids conforme de leur vecteur de plus haut poids, et par la charge centrale c, le facteur de l'extension centrale, commune a toutes les representations d'une meme theorie. Les theories conformes minimales sont constituees d'un nombre fini de representations. Parmi celles-ci se trouvent des theories unitaires dont les representation forment la serie discrete de l'algebre de Virasoro; leur poids h a la forme h_{p,q}(m)=[ (p(m+1) -qm)^2-1] (4m(m+1)), ou p,q et m sont des entiers positifs et p+q= 2. Ces representations possedent un sous-espace invariant engendre par deux sous-representations avec h_1=h_{p,q} + pq et h_2=h_{p,q} + (m-p)(m+1-q) dont chacun des vecteurs de plus haut poids portent le nom de vecteur singulier et sont notes respectivement |Psi _{p,q}> et |Psi_{m-p,m+1-q}>. . Les theories super-conformes sont une version super-symetrique des theories conformes. Leurs champs appartiennent a des representation de plus haut poids de l'algebre de Neveu-Schwarz, une des deux extensions super -symetriques de l'algebre de Virasoro. Les theories super -conformes minimales possedent la meme structure que les theories conformes minimales. Les representations sont elements de la serie h_{p,q}= [ (p(m+2)-qm)^2-4] /(8m(m+2)) ou p,q et m sont

    2012-01-01

    Full Text Available Cette recherche exploratoire rend compte des modalités de formation des formateurs d’enseignants dans deux établissements d’enseignement du canton de Fribourg, en Suisse. Neuf formateurs d’enseignants ont été interrogés sur leurs parcours de formation et d’autoformation en matière de compétences technologiques et d’intégration des TICE. Les résultats montrent que, même si ces formateurs ont acquis des compétences technologiques, les dispositifs d’enseignement-apprentissage qu’ils mettent en place pour former de futurs enseignants intègrent relativement peu les TICE. En outre, les propos tenus montrent que les formateurs déploient des stratégies d’autoformation plus ou moins efficaces et coûteuses en temps pour les aspects techniques, mais n’usent presque jamais de ce type de procédé pour développer une intégration pédagogique des TICE dans leurs cours. La fin de l’article reprend ces éléments et les discute en essayant de présenter quelques pistes en articulant formation formelle et informelle dans le contexte de la formation des enseignants.

    2015-11-01

    Full Text Available Verb aspect, alternations and quantification In this paper we are briefly discuss the nature of Bulgarian verb aspect and argue that the verb aspect pairs are different lexical units with different (although related meaning, different argument structure (reflecting categories, explicitness and referential status of arguments and different sets of semantic and syntactic alternations. The verb prefixes resulting in perfective verbs derivation in some cases can be interpreted as lexical quantifiers as well. Thus the Bulgarian verb aspect is related (in different way both with the potential for the generation of alternations and with the prefixal lexical quantification. It is shown that the scope of the lexical quantification by means of verbal prefixes is the quantified verb phrase and the scope remains constant in all derived alternations. The paper concerns the basic issues of these complex problems, while the detailed description of the conditions satisfying particular alternation or particular lexical quantification are subject of a more detailed study.

    The colorimetric analysis of images recorded with an optical microscope during the onset of the spin crossover transformation allows monitoring separately the involved electronic and structural aspects, through the separation of resonant absorption and scattering effects. Complementary information can also be obtained by using the polarized modes of the microscope. These potentialities are illustrated by the observation of [Fe(ptz)(6)](BF(4))(2) single crystals during the onset of the thermal transitions in the 110-140 K range. We characterized the interplay between the electronic (HS LS) and structural (order disorder) transformations. Elastic stresses and mechanical effects (hopping, self-cleavage) generated by the volume change upon electronic transition are also illustrated, with their impact on the photoswitching properties of the crystals.

    Full Text Available In the process of preparing a state for the accession to the Euro Zone it is essential to analyze the price competitiveness of that state’s economy and the challenges that entrepreneurs will have to face in the new economic environment. In the present paper the authors want to capture some aspects of the competitiveness of the Romanian economy and implicit its entrepreneurs with emphasis on price competitiveness, whereas accession to the Euro Zone implies giving up to the independence of exchange rate policy, with a huge impact on price competitiveness. For this purpose this study will highlight a few elements on the relative importance of price competitiveness of entrepreneurs’ exports performance. The process of accessing Euro Zone creates significant changes in the existing way of conducting business and impacts significantly entire business environment – and this will become evident also for Romania.

    The numerical simulation has been applied for studying of Bragg-case section topographic images of dislocation and rod-like inclusions. The validity of simple approximation of extinction contrast was confirmed in the case of screw dislocations in silicon carbide crystals. A procedure for approximate calculation of the strain field of rod-like inclusion was constructed, consisting of adding the contributions from a very large number of point-like inclusions uniformly distributed inside the assumed volume of the inclusion. The procedure ensured a reasonable similarity between the simulated topographs and experimental Bragg-case section topographic images of some pipe-formed cavities in silicon carbide crystals. The method is useful for some other materials, e.g. it enabled to compute realistic simulation of plane-wave topographs of the rod-like inclusions in YAG. (authors)

    Full Text Available The UK is said to have the largest number of CCTV cameras of any European nation. These cameras have been involved in a variety of changes in UK police practices. Such changes range from new evidential practices in court cases, through access to new materials, to new questions posed regarding invasions of privacy. One unexplored area of police practices, which this paper will argue have undergone significant changes since the introduction of CCTV cameras, is police accountability. This paper will draw on recent controversies in the UK regarding police car chases to investigate the ways in which CCTV cameras have led to new and complex questions of police accountability.Le Royaume-Uni est souvent présenté comme le pays ayant le plus grand nombre de caméras en Europe. Ces caméras ont joué un rôle dans bien des changements intervenus au sein des pratiques de la police britannique, depuis la production de nouveaux types de preuves devant les tribunaux, en passant par l’accès à de nouveaux matériaux et à de nouvelles informations, jusqu’à la mise en lumière de nouvelles questions touchant aux violations de la vie privée. Un des aspects peu explorés parmi ces nouvelles pratiques policières concerne la question de la responsabilité et le fait, pour la police, de rendre des comptes. Cet article porte précisément sur les changements significatifs provoqués par l’introduction de caméras de vidéosurveillance dans la façon d’accomplir les activités policières. À partir du cas de controverses récentes au Royaume-Uni autour de courses poursuites dans lesquelles sont engagés des véhicules de police, il s’intéressera aux façons dont la présence et l’usage de caméras de vidéosurveillance ont amené des questions à la fois nouvelles et complexes, concernant la justification des actions de police.

    Full Text Available Introduction Envenomation by scorpion stings is a major public health problem in numerous tropical countries because of its frequent incidence and potential severity. Approximately 1,900 species of scorpions are known in the world, and at least 130 of these have been described in Brazil. Methods This work reports on 3 child deaths caused by Tityus stigmurus stings and characterizes epidemiological and clinical surveys on pediatric cases of scorpionism recorded in the Centro de Assistência Toxicológica de Pernambuco (Ceatox-PE. Results Scorpion stings accounted for more than 60% of all cases recorded for venomous animals. The children were from 37 cities of the Pernambuco state and accounted for 28.8% of the victims treated for scorpion stings, with the highest incidence in the metropolitan area of Recife. Stings occurred throughout the year and slightly increased during the rainy season. Independent of the elapsed time for a prognosis, most cases showed mild symptoms. Three moderate cases that resulted in death featured cardiogenic shock and/or pulmonary edema or severe neurological symptoms. For the first time, death attributed to T. stigmurus was confirmed by the presence of the scorpion. Conclusions These results suggest that scorpionism in Pernambuco is a public health problem that needs to be monitored carefully throughout the year by the government.

Dans le réseau de la santé au Québec, on a observé réduction importante de leur nombre de cadre de premier niveau. Or, ceux-ci jouent un rôle important quant à la santé (physique et psychologique et à la sécurité des membres des équipes de travail, puisqu’ils définissent certaines des conditions de réalisation de leur travail et certains aspects de leur environnement psychosocial de travail. L’étude, visant à mieux comprendre le travail de ces cadres et l’influence des conditions dans lesquelles il est réalisé, a procédé par des observations auprès de 12 cadres de premier niveau, sous forme de chroniques de travail et par des entretiens sur la base de ces observations. L’article présente et discute trois types de résultats : des exemples de la manière dont la tâche prescrite est convertie en tâche effective et de sa traduction dans leur activité ; une synthèse de la manière dont ils perçoivent leur rôle ou « tâche effective » ; des constats quant à l’écart entre celle-ci et les conditions de réalisation de leur travail, en particulier du fait d’une surcharge quantitative de travail, d’une autonomie réelle limitée et d’obstacles à la planification et au développement à long terme de leurs services, Ces conditions n’apparaissent donc pas favorables au rôle positif qu’ils souhaitent jouer et qui est attendu d’eux, par rapport à leurs équipes de travail.First-level managers’ work has undergone many changes in recent years.

    Les nodules thyroïdiens sont très fréquents et moins de 10% d'entre eux sont malin. Ils posent un véritable problème diagnostique et thérapeutique surtout par rapport à leur nature bénigne ou maligne. L’étude de certains facteurs cliniques et paracliniques de présomption de malignité permet de bien codifier la stratégie thérapeutique. Le but de ce travail est d’étudier les facteurs prédictifs de malignité des goitres nodulaires et comparer nos résultats à ceux de la littérature. Il s'agit d'une étude rétrospective à propos de 500 cas de goitres nodulaires opérés au service d'Oto-rhino-laryngologie (ORL) et Chirurgie cervico-faciale (CCF) de l'hôpital militaire Avicenne de Marrakech entre 2006 et 2012. Le pourcentage de cancers a été de 6,8%. L’âge moyen de nos patients était de 46 ans, avec une sex-ratio de 5 (F/H). A la palpation cervicale; le caractère dure du nodule a été constaté dans 94,4% des cas de cancer, avec des limites irrégulières dans 64,70% des cas de cancer. Trois nodules étaient fixes et ils étaient tous malins. Les adénopathies cervicales ont été constatées chez 8 malades dont 7 présentaient des cancers. A l’échographie, 61,8% des nodules malins présentaient un aspect hypoéchogène, avec des contours flous dans 88,24% des cas. La vascularisation intra nodulaire était présente dans 35,3% de ces cas des cancers avec des microcalcifications chez 55,9% d'entre eux. Le halo hypoéchogene périnodulaire était incomplet dans 73,5% des cas de cancer. Nos patients étaient en euthyroïdie dans 84,6% des cas. Les facteurs prédictifs de malignité d'un goitre nodulaire, étaient donc dans notre étude d'abord cliniques: l’âge supérieur à 60 ans, la consistance dure du nodule, sa fixité, son caractère irrégulier et mal limité à la palpation, ainsi que la présence d'adénopathie(s) cervicale(s) à l'examen; et échographiques: le caractère hypoéchogène, les limites floues, la présence de

    The present communication is devoted to a body of theoretical and experimental work carried out at the C.E.A. with the aim of adding to the current knowledge on the evolution of the reactivity (during fuel irradiation) in natural or slightly enriched Uranium reactors. The difficulties of performing direct experiments on large amounts of irradiated fuels are reviewed - especially in operating power reactors - and the necessity is underlined for fundamental research in two directions: on one hand, the change in the composition of the fuels (chains of heavy nuclei, fission products), and on the other hand the effect of changes in composition on the neutron balance. Before presenting three types of experiments which have been carried out, the importance of the problems associated with the neutron spectra is stressed and the practical methods used for the calculations are briefly described. The systematic irradiation of several types of fuel, followed by their chemical and isotopic analysis has been going on for several years. An outline of the experimental programme is given with a description of the methods employed: {alpha}, {beta}, {gamma} chain for the preparation of samples determination of the plutonium content by coulometry and double isotopic dilution, separation of Boron used in some cases for the measurement of integrated neutron densities. The interpretation of the measurements is discussed with some examples. A second and more recent series of experiments deals with the investigation of lattices, using synthetic fuels (Uranium-Plutonium alloys) as compared to slightly depleted or enriched Uranium Various experiments are considered on heavy water and on cold graphite, then on graphite heated up to 500 C Some results already obtained are listed. These experiments, requiring nearly a metric ton of each type of fuel cannot be pursued in a systematic manner. This is why is developed since several years a method of differential measurement by oscillation, which

    Full text: In preparing for the first nuclear power plant in Vietnam, as part of the quality assurance, it is important to educate and train the staff of the plant beforehand. Such training includes, amongst other important subjects, the scientific background on the complex processes, the operational safety, use of the instruments for reading and controlling parameters, evaluation of these data, the quality management system, and staff responsibilities and interactions during routine and non-routine activities. This paper refers to the one aspect of operating a nuclear power plant: the water chemistry. Various important parameters of the plant, such as reactivity, corrosion rate, dose rate, material stress, interreaction and/or behaviour between water coolant and materials, filter lifetime, and heat exchanger efficiency can be influenced and/or controlled in terms of water composition, radionuclides arising during starting stage,during operation and in shutdown stage, its pH, additives, water management and purification. Also, ecologic considerations play an essential role. We report here about a project to establish such education and training as one of the missions of our institute in terms of support for the new nuclear power plants in Vietnam. (author

The sheep are kept by women aged of 32.5 n 5.7 years, of the ethnic groups Mossi (80/ and Peul (20/. 75/ of the sheep are rams of Sahelian breed and 25/ are crossbreeds of Sahelian x Djalonke. The length of fattening period is 10 months on average starting at an age of 8 months and ending at 18 months. This period leads to the following expenses (in CFA francs, 1 CFA F = 0,01 French franc: purchase of the sheep (13,500 CFA F, veterinary treatments (5,000 CFA F, feed costs (15,000 CFA F, various expenses (3,350 CFA F, adding to an average total cost of 36,850 CFA F. The rams are sold to intermediate tradesmen in the village just before the Tabaski at an average price of 27,000 n 4,000 CFA F. The result shows on average a negative balance of 9,850 CFA F. Nevertheless, this sale is satisfactory for the women who do not consider as important the costs of feed which comes from the exploitation of natural resources. Three complementary ways are identified to increase profitability of household sheep fattening: 1 to improve the management of sanitary and genetic constraints ; 2 to increase average selling price of rams compared, at least, to the cost price; 3 to develop a marketing campaign emphasizing quality-price ratio and social impact of the activity.

    The first three chapters of these lecture notes are devoted to generalities concerning current algebra. The weak currents are defined, and their main properties given (V-A hypothesis, conserved vector current, selection rules, partially conserved axial current,...). The SU (3) x SU (3) algebra of Gell-Mann is introduced, and the general properties of the non-leptonic weak Hamiltonian are discussed. Chapters 4 to 9 are devoted to some important applications of the algebra. First one proves the Adler- Weisberger formula, in two different ways, by either the infinite momentum frame, or the near-by singularities method. In the others chapters, the latter method is the only one used. The following topics are successively dealt with: semi leptonic decays of K mesons and hyperons, Kroll- Ruderman theorem, non leptonic decays of K mesons and hyperons ( {delta}I = 1/2 rule), low energy theorems concerning processes with emission (or absorption) of a pion or a photon, super-convergence sum rules, and finally, neutrino reactions. (author) [French] La premiere partie de ce cours (trois premiers chapitres), traite des generalites concernant l'algebre de courants. Apres une definition rapide des courants faibles et un rappel de leurs proprietes (hypothese V-A, conservation du courant vecteur, regles de selection, courant axial partiellement conserve,...), l'on introduit l'algebre de Gell-Mann SU (3) x SU (3), et discute les proprietes generales de l'Hamiltonien faible non leptonique. Les chapitres IV a IX sont consacres a des applications importantes de l'algebre des courants.

    Eating epilepsy is an uncommon form of reflex epilepsy. The authors present a case report of a patient with clinical diagnosis of eating epilepsy who was submitted to clinical tests, neuroimaging studies (MRI and SPECT) and surface EEG. Multiple intercritical EEGs showed sharp discharges in the posterior left temporal area. The MRI did not show any abnormality. The intercritical brain SPECT showed clear hypoperfusion in the posterior left temporal area; so confirming the epileptogenic focus in producing the partial complex seizures triggered by eating.

    Since the introduction of the modern psychiatric diagnosis systems anxiety disorders have been intensively discussed. As clinical subtypes in panic disorder the cardial type and the vestibular type are widely accepted. We describe in a case report another of these subtypes, the pharyngeal type; it is characterised by symptoms that are related to the pharynx such as feeling a lump in the throat, swallow disturbance or pain in the pharynx region. It may therefore be called "throat-anxiety syndrome" or "phagophobia". Nosological implications are also discussed.

    The results given in this paper are based on the fact that the best way of burying fission products is to incorporate them in vitrified fused blocks containing these fission products. The physico-chemical bases of the transformation of liquid waste into solid blocks are shown. The thermogram of this process is presented and the analysis of its characteristics given. The conditions of fusion of the vitrified mass, in particular those contributing to the fixation of radioactive aerosols, are shown. Some results of studies on the chemical state of radioactive fission products in the solid mass in connexion with the leaching of their radioactivity are given. In conclusion, the results of calculations of the temperatures up to which the radioactive blocks may be heated according to their characteristics are presented.

    Full Text Available Choledochal cyst (CDC is a congenital dilatation of the extra and/or intrahepatic bile ducts and it is a rare condition in western countries. Classical treatment consists of cyst excision and hepaticojejunostomy. The first case of a laparoscopic CDC excision was described in 1995 and since that time an increasing number of institutions have adopted this technique, with good success. We describe our early experience of 3 cases of CDC treated with laparoscopic approach. We used a 10 mm umbilical port for the camera, and four 3-5 mm operative ports. We performed the laparoscopic removal of the cyst and gallbladder, videoassisted preparation of the Roux-en-Y loop and laparoscopic hepaticjejunostomy. No post-operative complications occurred. Laparoscopic excision of CDCs has been supposed to give better observation, a better cosmetic result, potentially less postoperative pain, and a shorter recovery. The main argument for performing an extracorporeal anastomosis is that it decreases the operative time. We recommend caution to prevent injury to the pancreatic duct and biliary structures during dissection and anastomosis. Lifelong surveillance is mandatory, even after resection of the choledochal cyst.

    Full Text Available Au Burkina-Faso, la boucle du Mouhoun constitue un foyer historique des trypanosomoses humaines africaines (THA et animales africaines (TAA, transmises par les glossines. Aujourd’hui, la THA semble avoir disparu de cette région après quelques soubresauts dans les années 1970, tandis que la TAA continue de sévir. Afin de mieux comprendre ces évolutions divergentes, nous avons mené une étude géographique basée sur l’analyse de photographies aériennes entre 1952 et 2007, ainsi que d’enquêtes de terrain sur les aspects médicaux, entomologiques et vétérinaires des trypanosomoses. Il apparaît que le paysage de cette région a connu en l’espace d’un siècle des modifications intenses, notamment du fait de l’augmentation des densités de population et des surfaces cultivées, qui n’ont pas été sans conséquences sur le nombre et la distribution des mouches tsé-tsé. Associée à la lutte médicale qui avait permis la stérilisation du réservoir humain de trypanosomes dans les années 1940, cette dégradation paysagère, accompagnée du développement des aménagements hydrauliques et d’évolutions des modalités de migration des hommes et des animaux, semble pouvoir expliquer ces disparités THA/TAA. La mise en évidence de ces facteurs, et leur prise en compte lors d’études ultérieures menées dans d’autres régions, devrait permettre de délimiter des zones d’intervention prioritaires contre les trypanosomoses et leurs vecteurs dans un contexte de lutte internationale contre ces pathologies.

    Full Text Available Introduction: Although there has been considerable discussion regarding the presence of therapeutic aspects of humour in the nurse educational programme and syllabus, little is known about the use of humour in the nurse - patient relationship and the needed topics in the Slovene educational system for nurses. From educational and medical perspectives, humour is anything that evokes laughter and it has been proven that laughter contributes to physical health. A sense of humour in nursing has a conformist, quantitative and productive importance which is manifested through the essential elements of humour: meta-communication sensitivity, personal affection for humour and emotional admissibility. As nurses spend a lot of time with patients, humour adds to the quality of their work as well as to the nurses’ satisfaction with their work with patients. The aim of this paper is to contribute to a better understanding of the significance of humour in nursing both for the employees and for the patients and to discuss humour within the framework of nursing profession in Slovenia. The specific objective of our study is to explore the attitudes of Slovenian nurses towards humour and their actual use of humour during their interaction with patients. Methods: For the purpose of this study, a quantitative research methodology was adopted. A questionnaire was used to collect data on the topic and a set of statistical analyses (frequency distribution method, the χ2 and Spearman rank correlation test was performed on the data obtained. Results: Our study shows that Slovenian nurses are prone to the use of humour in their work and they welcome it as an integral part of their work with patients. We found that humour also enhances their sense of belonging to the nursing profession and serves as a tool for socialization. Discussion: Humour, employed in nursing can help overcome certain difficulties which nurses face in the workplace as they also try to fulfil some

    Full Text Available A anomalia de Peters consiste na mais comum opacidade corneana congênita e é secundária à malformação do segmento anterior do olho. Suas principais características são opacidade corneana central e sinéquias da íris e/ou do cristalino com a região do leucoma. Pode apresentar-se de forma isolada ou associada a outras anomalias oculares e sistêmicas, tendo prognóstico mais sombrio nestes casos. A etiologia da anomalia Peters permanece incerta, sendo aventadas causas genéticas, infecciosas, traumáticas e tóxicas. O tratamento varia com a apresentação do quadro, sendo importante a pronta detecção da doença, possibilitando o tratamento precoce, com bom desenvolvimento da visão. Este trabalho relata um caso de anomalia de Peters diagnosticado tardiamente e discute as características da doença e possibilidades de tratamento.Peter's anomaly consists in the most common congenital corneal opacity related to a malformation of the anterior segment of the eye. Its main characteristics are central leukoma and iridocorneal adherences at the area affected by the leukoma. It can be identified isolated or in association with other ocular or systemic abnormalities, and the prognostic tend to be worse in the latter cases. The etiology of Peter's anomaly remains uncertain, but the most likely causes are related to genetic, infectious, traumatic and toxic factors. A range of possible treatment strategies exists, though the effectiveness of each of them depends on how the disease occurs and whether it is identified in early or advanced stages - the earlier the diagnosis, the higher the possibility of a successful intervention, given that precocious treatments are more likely to result in a good development of the vision. This work reports a case of Peter's anomaly that was diagnosed in an advanced stage, discussing the characteristics of the case and treatment possibilities.

    Le neutron est une particule élémentaire qui a été découverte en 1932 par James Chadwick. Ses caractéristiques principales sont résumées dans le tableau I. Il a été utilisé pour la première fois par Clifford Shull en 1946 comme outil pour des expériences de diffusion. Cette technique s'est depuis constamment développée pour concerner tous les aspects de la matière condensée: physique, chimie, matériaux, biologie. Il s'agit d'un outil tout à fait exceptionnel car le neutron possède des propriétés uniques et particulièrement adaptées pour ces études.

    Introduction Globally, laws and guidelines for managing conflict of interest are increasingly implemented to achieve transparency in financial ties between physicians and pharmaceutical and medical device industries, yet little information is available regarding the limitations of the current frameworks for disclosing these financial ties. Case In June 2017, the Capecitabine for Residual Cancer as Adjuvant Therapy (CREATE-X) trial was published in the New England Journal of Medicine. In this study, which suggested the post-surgery addition of capecitabine would improve survival of high-risk breast cancer patients, the cost of capecitabine for off-label use was illegally claimed to the Japanese public health insurance system, rather than being covered by the research budget. This illegal claim led to the profit of more than 100,000,000 JPY (approximately 0.91 million USD) for Chugai Pharmaceutical Company (CPC), which manufactures capecitabine. Additional evidence suggests that the CPC made donations of at least 100,000,000 JPY (approximately 0.91 million USD) and 236,000,000 JPY (approximately 2.1 million USD) to the Japan Breast Cancer Research Group (JBCRG), the study's sponsor and funder where the majority of the Japanese authors served high-level positions, and the Advanced Clinical Research Organization, the other study funder, respectively, during the study period, though the total amount has not been clarified. Neither the CPC's involvement nor its undue profit was mentioned in the published article. Conclusion This case report highlights the lack of financial transparency in the CREATE-X trial, and discusses the potential limitations that may exist in the current frameworks for disclosing financial ties between physicians and relevant industries in clinical trials. Achieving improved transparency is essential to heighten credibility in the findings of clinical trials.

    The author examines the origin and nature of radioactive waste generated in the use of radioisotopes in industry, medicine, agriculture and research and studies the relationship between types, quantities and uses of radioisotopes and disposal of the radioactive waste generated in their use. He also discusses the methods used for the disposal of such waste under the licensing controls of the United States Atomic Energy Commission. These methods include: 1. The controlled discharge of low concentrations of effluents into streams and into the atmosphere; 2. Controlled release of small quantities of soluble or readily dispersible waste products into sanitary sewage systems; 3. Burial, under controlled conditions, of small quantities of waste in the soil ; 4. Return to AEC installations of radioactive waste for storage or land burial ; 5. Treatment by incineration; and 6. Disposal of packaged waste at sea. The paper reviews the criteria and regulatory requirements applicable to cach method of disposal to accomplish the objective of preventing the waste from entering the food chain of man in hazardous quantities, or of adversely affecting the use of the environment by man. It goes on to discuss the limitations on the types, quantities, and methods of disposal for which private concerns can be licensed due to long-term responsibility for maintenance of burial grounds or storage facilities.

    Full Text Available Background: Patients as customers of health services actually have expectation and assessment of health services perceived. During the initial interview conducted at Waru Sidoarjo Community Dental Health Service (Waru Sidoarjo CDHS, it is known that one hundred percent of initial respondents were not satisfied with dental care service provided. All of those respondents assessed that Waru Sidoarjo CDHS still has not met their expectations of service quality factors considered to be important for them. It is even known that there is usually a gap between the expectations of quality dental care service and the assessment of services perceived. As a result, further researches are needed to be conducted regarding the level of importance and achievement-related with factors that affect the quality of health services. Purpose: The purpose of this study was to determine the level of importance and achievement of the quality aspects of the health service provided by Waru Sidoarjo CDHS. Methods: This study can be considered as a descriptive observational study. The instrument used in this study was measurement instruments of service quality. Respondents in the study were 200 patients who visited to dental care services in Waru Sidoarjo CDHS in July 2011. Results: All of the attributes had a mean value of dominant importance and assessments at four. The attributes of the appearance feasibility of medical staffs had the highest interest, about 4.780. Meanwhile, the mean value of the lowest importance was on the attributes of the service suitability, about 4.595. During the observation of the service value, it is also known that the highest mean value was on the non-discriminative services, about 4.600. Conclusion: It can be concluded that there were attributes considered to be important for patients, but still not being fully met by health services provided by the service provider or Community Dental Health Care.

    Full Text Available La LGV est-européenne a été mise en service le 10 juin 2007. Les acteurs économiques des territoires desservis attendent beaucoup de cette arrivée notamment en matière de développement des tourismes urbain et d’affaires. Mais un tel développement n’est pas automatique. C’est l’appropriation collective de l’innovation que constitue la desserte à grande vitesse dans un territoire qui est au coeur de ses effets positifs. En effet, cette appropriation collective constitue une innovation relationnelle de laquelle peuvent naître des innovations de services complémentaires en matière de tourisme susceptibles de valoriser les ressources spécifiques existantes (patrimoine historique, culturel, gastronomique, etc.. Ainsi, si l’existence de ressources spécifiques joue un rôle pour les villes desservies, les efforts coordonnés des acteurs pour favoriser la “mise en tourisme” de la ville sont également décisifs. L’analyse est illustrée par le cas de l’agglomération rémoise.The East European High-Speed Rail started on June 10, 2007. Economic actors of beneficiary territories are expecting a lot of positive effects such as the development of urban and business tourisms. But such development is not automatic. The collective appropriation of the innovations linked to a High-Speed Rail Service seems to be central for generating positive effects. Indeed, this collective appropriation constitutes a relational innovation, which may give birth to additional services innovations in tourism that could enhance the value of existing specific resources (historical, cultural, gastronomic, etc. and turn them into assets. Thus, if the availability of specific resources plays a specific role for the connected cities, coordinated efforts of actors to promote the tourist development of the city are also decisive. We will illustrate our subject with the case of Rheims.

  20. Tombes et cimetières éthiopiens : des rois, des saints, des anonymes1

    L’histoire des tombes et cimetières éthiopiens, dans la longue durée, en est encore à ses balbutiements. Si les tombes des saints et des rois nous sont un peu mieux connus grâce à des textes témoignant à la fois des enjeux entourant les sépultures de ces personnages hors du commun et des soins apportés à leur inhumation, en revanche, les cimetières ordinaires échappent encore largement à l’enquête, en grande partie parce que le commun des mortels est inhumé dans l’anonymat et dans un grand dé...

  1. Geophysical Well Logs Applied to Geothermal Resource Evaluation Application des diagraphies à l'évaluation des ressources géothermiques

    Full Text Available Well logging in the petroleum industry has been developed over five decades into a mature industry, whereas geothermal well logging is a relatively new enterprise. Fundamental differences also occur in the geologic environments and key objectives of both logging applications. Geothermal reservoirs are frequently in fractured igneous and metamorphic rocks, which contain hot water or stem at temperature exceeding 150°C. The discussion focuses on present day logging technology, geologic and reservoir engineering objectives, and qualitive and quantitative formation interpretation techniques for geothermal resource evaluation. Specific field case studies illustrate the interpretive state-of-the-art, including examples from the Geysers dry steam field in the Imperial Valley of California, hot water fields in California, Nevada, and Idaho, and the LASL Hot Dry Rock test project in the Valles Caldera of New Mexico. Les diagraphies dans les forages pétroliers ont atteint leur maturité, alors que le contrôle diagraphique des sondages géothermiques est une entreprise relativement nouvelle. Des différences fondamentales apparaissent aussi dans les environnements géologiques et dans les objectifs clés des deux types d'applications des diagraphies. Les réservoirs géothermiques se situent souvent dans les roches ignées ou métamorphiques fracturées qui contiennent de l'eau chaude ou de la vapeur à des températures dépassant 150 °C. L'exposé sera concentré sur les techniques actuelles d'enregistrements, les objectifs géologiques et liés à l'exploitation des réserves et sur les techniques qualitatives et quantitatives d'interprétation des formations pour l'évaluation des ressources géothermiques. Quelques cas particuliers illustrent l'état actuel des techniques d'interprétation avec des exemples pris dans le champ de vapeur sèche des geysers dans Imperial Valley de Californie, des champs d'eau chaude en Californie, Nevada et Idaho et

    Full Text Available In the current context of reinventing the trading company law, at the end of a lengthy and extremely difficult economic crisis, when every participant in the economic life tried to find their own way to adapt and make their activity survive the new social and commercial realities, not few were the cases when some of the Shareholders were excluded and their liability was drawn onto the legal person itself. Nevertheless, there is a type of legal liability of the former Shareholders, excluded from the Company, that still is quite deficiently regulated and, despite the sound argumentation and comprehensive regulation of Law no. 31/1990, it fails to provide a clear and detailed explanation of the consequences, namely, of the consequences the exclusion of a Shareholder has over the Third Parties of good-faith that the legal person (the Company had or continues to have legal relations with. This paper thus aims at analysing one of the main effects of excluding Shareholders from the company, namely the extent of their liability towards the Third Parties, and it is structured in five parts, as follows: 1 Introduction, 2 About the Shareholders’ exclusion, 3 The effects of excluding a Shareholder from the Limited Liability Company, 4 The excluded Shareholder’s liability towards the Third Parties and 5 Conclusions.

O silêncio elétrico e os potenciais polifásicos e gigantes constituíram as anormalidades mais freqüentemente notadas. Em pequeno número de casos registraram-se salvas ou alterações pseudomiotônicas. Dentre os pacientes que revelaram sinais indicativos de desenervação recente, 50% apresentavam resultados bacterioscópicos negativos. Havia predominância das anormalidades eletromiográficas nas formas virchovianas. Em relação aos nervos pesquisados, houve maior comprometimento do ulnar, seguindo-se os peroneos profundos e mediano. O estudo da velocidade média de condução das fibras motoras nos nervos mediano, ulnar e perôneo profundo, permitiu a obtenção dos seguintes resultados: 53,6; 48,1 e 50,3 m/seg. As médias das latências distais e proximiais do nervo mediano foram de 3,8 e 8,4; no ulnar, de 3,0 e 9,2; nos perôneos profundos, de 4,4 e 11,6 m/seg.By the neurological, electromyographic, anatomopathological and bacterioscopic examinations of 100 pacients with leprosy the following conclusions have been drawn: There was a high incidence of reflex abnormalities. The proprioceptive reflexes were abnormal in 64.5% and the superficial reflexes in 70.8% of the cases. According to the topography of the segments examined, the deep reflexes showed the following abnormal values: 25.3% in the cephalic segment; 69.1% in the upper limbs and 74.5% in the lower limbs. Of the 2,289 reflexes investigated, abnormalities were found in 773 superficial reflexes (70.8%, while in relation to the proprioceptive reflexes the figures rose to 901 (64.5%. In the early stages of the infirmity, the reflexes were normal in 41.2% of the cases examined, and in all the stages of the evolution of the disease those numbers were always high.

    Full Text Available Aim/purpose - The objectives of the paper include: identification of factors that influence the directions of fluctuations of foreign exchange rates seen as manifestations of currency wars; description of the most important forms of currency wars conducted in the contemporary global economy (including in particular the currently observed third currency war; analysis of risks to contemporary financial markets and national economies posed by the third currency war. Design/methodology/approach - The paper uses the method of critical analysis of the literature on the subject, as well as US-China and Brazil case analyses. The Propensity Score Matching method was used in the study. Findings - The research findings confirmed the following hypotheses: contemporary fluctuations of foreign exchange rates in the largest economies of the world confirm that the third currency war is ongoing; the risk of consequences of the currency war destabilises the international and local financial markets and trade transactions among them. Research implications/limitations - The limited scope of the research performed is due to the fact that emerging economies have no control of devaluation or revaluation processes in their respective countries. However, large economies, such as China or Japan, are able to create the value of their respective currencies, thus artificially controlling the competitiveness of their products and services. These differences between small and large economies limit and distort the scope of the research done.

    The field studies on the residue levels of the fungicides and insecticides used in commercial raspberry (Rubus idaeus L.) plantation have been performed. Starting on the first day of harvesting (on June 19), 20 laboratory samples of fruit, 10 laboratory samples of leaves and 4 samples of soil were analyzed and the residue levels were compared to the Maximum Residue Limits (MRL) and Acceptable Daily Intakes (ADI). All analyses were carried out using extraction method and gas chromatography technique. Esfenwalerate (Sumi-alpha 050 EC) and beta-cyfluthrin (Bulldock 025 EC), the insecticides belonging to the group of synthetic pyrethroids, were not found in harvested ripe fruits, while cypermethrin residues (Cyperkill 25 EC) applied on May 24, 25 days later was still found on low levels in fruits (0.026 mg kg(-1)) and in leaves (2.58 mg kg(-1)). In turn, residues of chlorpyrifos (Dursban 480 EC), applied to the soil on May 15 against the cockchafers Melolontha melolontha and Otiorhynchus sp., were found at the level 0.004 mg kg(-1). The content of pesticides in ripe fruits depended mainly on the dose and on the time that has elapsed from the date of their application and were as follows: boscalid -0.950, pyrimethanil -0.917, pyraclostrobin -0.253 cypermethrin -0.026 and chlorpyrifos -0.004 mg kg(-1) while in leaves: boscalid -30.64, pyrimethanil -8.13, pyraclostrobin -15.82, cypermethrin -2.58 and chlorpyrifos -0.15 mg kg(-1). The highest average daily intake was in the case of boscalid, and in fruits and leaves reached the levels 0.205 and 6.63, in total 0.33% and 12.18% of ADI, respectively.

Malgré la protection juridique dont les jeunes travailleurs au Canada font l’objet, les jeunes de 15 à 24 ans sont exposés à un risque élevé de blessures traumatiques au travail. Étant donné que de nombreuses initiatives de prévention des blessures ciblant les jeunes travailleurs existent, les défenseurs des droits des jeunes et les employeurs doivent relever le défi de choisir quels aspects de la prévention vont être les plus efficaces afin d’y consacrer leurs efforts. Une analyse de la littérature universitaire et de la littérature grise a été entreprise afin de compiler les paramètres (indicateurs évalués et méthodes de mesure couramment utilisés pour évaluer les programmes de prévention des blessures auprès des jeunes travailleurs. Les paramètres constituent des références de mesure permettant d’évaluer l’efficacité, le rendement, le progrès ou la qualité d’un projet, d’un procédé ou d’un produit. Méthodologie. Nous avons utilisé le modèle PICO pour définir les termes de recherche.

    In the following report one can find first a short general view on the present situation of our knowledge concerning the nuclear fission process, namely on the nucleus going through the saddle-point. Then there are some aspects connected with the excitation energy of the fissioning nucleus. The measurements made at Saclay on the fast neutron fission cross-section of U{sup 233}, U{sup 235}, Pu{sup 239}, U{sup 238} are described at the beginning of this work. It appears that for U{sup 233} there is some characteristic shape modulation of the cross-section curve, in relation with the collective excited state of the deformed nucleus at the saddle-point. Good evidence of this is also given by the study of the relative fission rate with emission of long-range particles; it appears also that this ternary fission rate does not change substantially for neutron between thermal energy and 2 MeV, but that is very lower for the compound nucleus U{sup 239} than for even-even compound nuclei. At the end there are some experiments on the strong 4,5 MeV gamma-ray originated by slow neutron absorption in U{sup 235}. Time-of-flight device is used to establish that this 4,5 MeV gamma-ray seems mostly connected with radiative capture.

Les mesures de sections efficaces de fission induite dans {sup 233}U, {sup 235}U, {sup 239}Pu et {sup 238}U par des neutrons rapides effectuees a Saclay sont decrites en premier lieu; elles font apparaitre pour {sup 233}U une ondulation caracteristique du role des etats collectifs d'excitation du noyau deforme au point-seuil.

    This study presents five methods used to realize a transfer function on analog computer - method of operational amplifiers - method of successive integrations - method of the auxiliary variable - method of the Horner decomposition - method of the direct analog transposition. The method that seems to us the most interesting, this one of Horner, is exposed with some complements. The last method presents the study of a linear network (mechanical, electronic) by direct analog transposition, without having to calculate its transfer function. Several aspects are studied the economy or the material type, the simpleness of implementing the adaptation of coefficients to the computer, the introduction of initial conditions of input and output functions. Every method presented is discussed in function of these problems. The precision of the result is not studied here, but we can indicate that the methods treated here, do not include approximations other than these ones of the computer elements.

    installees sur des reacteurs nucleaires utilisent dans la partie du traitement des mesures en totalite ou en partie un calculateur numerique. La fiabilite du systeme est limitee par celle du calculateur, celui-ci representant un point commun pour tout le traitement DRG. Pour satisfaire aux exigences de la securite de fonctionnement il faudrait envisager dans certains cas de doubler le calculateur. L'utilisation d'un calculateur necessite comme interface entre l'equipement de detection et lui-meme des echelles fonctionnant en integrateur pour les impulsions sortant du detecteur. En ajoutant un certain nombre de circuits a ces echelles on est capable d'effectuer le travail demande actuellement au calculateur, en ce qui concerne le calcul. Ce raisonnement nous a conduit a une solution dite ''decentralisee'' en realisant des equipements specialises au niveau du prospecteur meme. Nous croyons que cette solution represente, en dehors de l'aspect de fiabilite, surtout un interet economique. Dans notre solution, le point commun dans le traitement d'information se situe maintenant non plus au niveau d'elaboration du resultat comme dans le cas du calculateur, mais a un niveau plus bas, dans l'impression des resultats. Meme dans le cas d'une defaillance du point commun, les resultats sont elabores, affiches et compares aux seuils d'alarme. Dans le cas d'une panne d'un equipement specialise les resultats de ce prospecteur ne sont plus disponibles, les autres restent en fonction. Il semble que cette solution represente un degre de fiabilite meilleur que la solution utilisant les calculateurs universels. L'utilisation d'une technique a tiroir interchangeable (MULTIBLOC) permet un remplacement rapide de l'equipement specialise en panne. L'emploi systematique des circuits integres (TTL) assure une fiabilite accrue de l'equipement. (auteur)

    The continued expansion of atomic Energy has led the S.C.R.G.R. to extend simultaneously the recovery of materials contaminated by use in radio-active media. The importance of this aspect of atomic Energy was not immediately obvious to those concerned but is now fully recognized due to the cost of the materials and installations, and also to the time required for the construction of special equipment for the C.E.A. Another very important reason is the dangers associated with the handling of contaminated material. The S.C.R.G.R. attacked this problem from the point of view of these dangers. It later became apparent to the users, once the decontamination methods had proved their worth, that the process presented advantages from the material and cost-saving point of view. (author) [French] Le developpement toujours croissant de l'Energie atomique a conduit le S.C.R.G.R. a developper parallelement la recuperation des materiels contamines par leur emploi en milieu radioactif. Cet aspect de l'Energie atomique n'est pas apparu des le debut aux utilisateurs mais s'est tres vite impose etant donne, d'une part, le cout des installations et du materiel, d'autre part le temps necessaire a la fabrication d'un materiel special aux travaux du C.E.A., enfin et surtout, les risques associes a la manipulation d'un materiel contamine. Les risques seuls ont ete pris comme point de depart a l'examen de ce probleme par le S.C.R.G.R. puis avec le temps, les methodes de decontamination ayant fait leur preuve, les utilisateurs ont alors apercu les aspects materiels et la rentabilite de la decontamination.

Ceci nous a permis de dégager la façon dont se déroule la migration. Il en ressort que les modalités du déroulement de la migration sont bien connues et relativement stables d'une année à l'autre, mais nous en sommes encore réduits à des hypothèses en ce qui concerne l'explication de son allure générale et de sa variabilité interannuelle. L'analyse des caractéristiques des individus montre une haute régularité interannuelle, on peut même parler d'un patron standard de l'évolution des individus en migration. L'action des principaux facteurs environnementaux sur les individus en migration apparaît assez nette, même si nous ne sommes pas en mesure actuellement de hiérarchiser leurs effets sur des flux migrants. Ce travail met en évidence la nécessité, pour appréhender les phénomènes migratoires et à plus forte raison pour établir un prémodèle de migration, de tenir compte de l'ensemble des aspects de la migration (tendance, facteurs modulateurs, épiphénomènes et caractéristiques des individus e n migration et d'utiliser des horloges écologiques adaptées.

    Full Text Available Les lipidoses constituent un groupe d'affections systématisées, caractérisées par une surcharge lipidique des tissus (en premier lieu du système réticulo-endothélial, accessoirement aussi de divers parenchymes. Le processus qui est à la base de ces "thèsaurismoses" consiste en une perturbation primitive du métabolisme des graisses et des substances apparentées, aboutissant à une infiltration lipidique des organes et entraînant des troubles cliniques variés et souvent très graves. La participation prépondérante du système nerveux central et de l'oeil aux désordres cliniques represente un des aspects les plus importants de la pathologie des lipidoses. Toutes ces affections, excepté la maladie de Hand-Schüller-Christian, offrent en outre un intérêt considérable à cause du rôle primordial que joue l'hérédité comme facteur étiologique.

    Full Text Available Cet article théorique explore comment les concepts de structure et d’action permettent une approche originale du concept de compétence dans le domaine des TIC. Cette approche relève d’une recherche de compatibilité entre des modèles issus des Technologies qui proposent les structures socio-techniques et ceux des Sciences Humaines qui organisent l’action des individus. Les modèles théoriques invoqués de domaines disciplinaires différents (sociologie, ethnométhodologie, psychologie sociale, linguistique, sciences de l’éducation et sciences de l’information-communication donnent au concept de compétence en TIC une nouvelle consistance, plus anthropocentrée et moins technico-pratique. Ils posent la question du rapport entre micro et macro, du rapport de l’individu au groupe, et posent aussi la question ontologique des structures. Les compétences ne se réduisent pas à la seule connaissance des aspects techniques, mais sont élargies à la maîtrise des conditions d’utilisation adéquate et des possibilités offertes par la technique. Utiliser les technologies, c’est construire de la relation grâce aux compétences communicatives des TIC.This theoretical article investigates how the concepts of structure and action allow an original approach of the concept of skill in the field of ICT. This approach concerns a search for compatibility between stemming models Technologies which propose the socio-technical structures and those of the Human Sciences who organize the action of the individuals.

First are examined the general factors affecting the selection of concretes for protection; some of the general aspects of radiation attenuation (fast and thermal neutrons, {gamma}) are then recalled. After an enumeration of the qualities and defects of conventional concretes, desirable or possible improvements are proposed: introduction of heavy elements for increasing the efficiency with respect to fast neutrons and {gamma}; increase in the hydrogen content (as H{sub 2}O), addition of absorbent products (B, Li, rare earths) for thermal neutron capture. A list is given of the principal products used for this purpose. Finally there is a rapid review of the preparation, the stability with time, and the resistance to radiation and to heat. Appendices and tables give details and numerical values. Appendix 1 deals with the question of water in concretes. Appendix 2 gives a classification of concretes based mainly on their density.

    Because of their massive utilisation, hydrocarbons are major pollutants of soils and aquifers. Biodegradation is a key aspect of the fate of pollutants in the environment. Such knowledge, concerns in particular the intrinsic biodegradability of the products and the distribution in the environment of competent degradative microflora. In this study, a methodology has been developed to assess the aerobic biodegradability of gasoline. It is based on the direct gas chromatographic analysis of all hydrocarbons, after incubation in optimal conditions, of gasoline fractions and of model mixtures. The results demonstrated first the quasi-total biodegradability of gasoline ({>=} 94%). Concerning the distribution in the environment of degradative capacities, even microflora from non polluted sites exhibited a high performance (total degradation rates at least 85%) but were limited concerning the degradation of trimethyl-alkanes, such as 2,2,4-trimethyl-pentane (iso-octane) and 2,3,4-trimethyl-pentane, and of cyclohexane. Samples of polluted sites exhibited more extensive degradative capacities with total degradation in half of the cases studied. Cyclohexane was always degraded by mutualism and/or co-metabolism. Trimethyl-alkanes with quaternary carbons such as iso-octane and/or alkyl groups on consecutive carbons were degraded by co-metabolism but could also support growth of specialized strains. A strain of Mycobacterium austroafricanum (strain IFP 2173) growing on iso-octane was isolated from a gasoline polluted sample. This strain exhibited the capacity to co-metabolize various hydrocarbons (cyclic and branched alkanes, aromatics) and in particular cyclohexane. M austroafricanum lFP 2173 was also able to use a large spectrum of hydrocarbons (n- and iso-alkanes, aromatics) as sole carbon and energy source. (author)

    Argumosa, A; Herranz, J L

    2000-06-01

    The economic magnitude of epilepsy is determined by its effect on the employment status of the patients, the cost of drug treatment for them and the healthcare system and the repercussion worldwide. Studies of the cost of the disease show that it has economic importance due to the sum of the direct and indirect costs caused by it. In the case of epilepsy, the results of studies in various countries led to the creation of a Commission on Economic Aspects of Epilepsy. The lack of epidemiological studies regarding epilepsy in Spain may explain the lack of publications on this subject in our country. The percentage of the total cost due to antiepileptic drugs is considerable and will probably increase in the future. The pharmaco-economic evaluation made by cost-benefit, cost-effectiveness, cost-usefulness analysis and studies to minimize costs should serve to use healthcare resources in the most effective manner and justify the rational use of the new antiepileptic drugs. The economic impact of epilepsy is added to the repercussion of the disease itself on the patient and his family. The different distribution of costs in children and adults with epilepsy suggest the need for intervention at an early age to try to reduce the long term economic and personal repercussions. The pharmaco-economic evaluation of the new antiepileptic drugs will make it clear whether their considerable cost is worth paying for their greater effectivity.

    Full Text Available Osteoporose ist in hohem Maß genetisch determiniert. Neue Wege der molekularbiologischen Forschung haben sich in den letzten Jahren auf diesem Gebiet etabliert. "Gene mapping" mit polymorphen genetischen Markern auf der Suche nach Phänotyp-assoziierten Genen ist ein aufwendiges, aber vielversprechendes Verfahren und wird durch die Erkenntnisse des Human Genome Projects beschleunigt. So wurde jüngst u. a. das Low-density Lipoprotein 5-Gen als wichtig für den Knochenstoffwechsel identifiziert. Kandidaten-gene wie Hormonrezeptor-, Cytokin- oder Kollagen-Gene werden hinsichtlich ihrer Gen-Gen- und Gen-Umwelt- Interaktionen untersucht und erlauben neue funktionelle Einsichten in Erkrankungen des Knochenstoffwechsels. Mutationen der Kollagen-Gene sind bei einigen seltenen Erkrankungen, wie dem Osteoporose-Pseudogliom-Syndrom oder der Osteogenesis imperfecta gefunden worden, könnten aber auch für häufige Varianten von Bindegewebsstörungen wie der congenitalen Hüftdysplasie verantwortlich sein, die etwa 10 % der weiblichen kaukasischen Bevölkerung in unterschiedlichem Ausmaß betrifft. Osteoporose am Schenkelhals und erhöhte Gelenkslaxizität sowie andere generalisierte Veränderungen des Knochen- und Kollagenstoffwechsels können hier möglicherweise ebenfalls durch Störungen des Kollagen I alpha 1-Gens erklärt werden. In Summe können wir zahlreiche neue Einsichten in die Pathophysiologie des Skelettsystems erwarten, die uns auch neue Zugangswege für Diagnostik und Therapie unserer Patienten ermöglichen werden.

    Quelle que soit la civilisation à laquelle il appartient, l'être humain cherche dans le ciel des réponses aux questions qu'il se pose sur son origine, son avenir et sa finalité. Le premier mérite de ce livre est de nous rappeler que l'astronomie a commencé ainsi à travers les mythes célestes imaginés par les Anciens pour expliquer l'ordre du monde et la place qu'ils y occupaient. Mais les savoirs astronomiques passés étaient loin d'être négligeables et certainement pas limités aux seuls travaux des Grecs : c'est ce que l'auteur montre à travers une passionnante enquête, de Stonehenge à Gizeh en passant par Pékin et Mexico, fondée sur l'étude des monuments anciens et des sources écrites encore accessibles. Les tablettes mésopotamiennes, les annales chinoises, les chroniques médiévales, etc. sont en outre d'une singulière utilité pour les astronomes modernes : comment sinon remonter aux variations de la durée du jour au cours des siècles, ou percer la nature de l'explosion qui a frappé tant d'observateurs en 1054 ? Ce livre offre un voyage magnifiquement illustré à travers les âges, entre astronomie et archéologie.

The study was based on an analysis of over 100 scintigrams of the pericerebral subarachnoid cavities. From this, the authors were gradually able to work out the normal and pathological symptomatology of this field, from the point of view of both cisternal morphology and fluid hydrodynamics. (author) [French] L'exploration des espaces sous-arachnoiediens pericerebraux par les radioisotopes (cisternographie radioisotopique ou 'RISA- cisternography' ) prend une place de plus en plus importante parmi les techniques neuroradioisotopiques de diagnostic. Elle fournit de precieux renseignements sur la permeabilite des espaces sous-arachnoiediens et sur la dynamique du liquide cephalo-rachidien (LCR). On doit actuellement la considerer comme indispensable et irremplacable dans le diagnostic de certaines affections neurologiques, tout comme la gamma-encephalographie et les techniques neuroradiologiques plus classiques (angiographie et pneumographie cerebrales). En effet, cet examen est seul a preciser l'aspect morphologique global des espaces sous-arachnoiediens pericerebraux; tout en renseignant sur la permeabilite des citernes pericerebrales et des sillons de la convexite, il fournit une image scintigraphique typique et symetrique, facile a observer, de face et de profil, des voies principales de circulation du LCR cisternal. L'image scintigraphique d'une citerne indique qu'elle est permeable et que l'espace sous-jacent l'est aussi.

  10. La production mondiale des vins

    1970-06-01

    On sait peu de choses précises sur l'origine de la culture de la vigne en Gaule. Il est probable qu'il existait des lambrusques sauvages dans les forêts et les sous-bois dont les habitants récoltaient les raisins pour les consommer à l'état frais et peut-être en tiraient-ils aussi une boisson fermentée comme ils le faisaient pour l'orge ou pour le miel (hydromel. Il est vraisemblable aussi que les navigateurs phocéens, venus commercer sur les rivages de la Méditerranée, apportèrent du vin aux gaulois, leur apprirent à tailler la vigne et finalement, en établissant des comptoirs, amenèrent des boutures de vignes de leur propre pays. On sait que les gaulois apprécièrent très vite le vin et ce fut une des raisons de leurs invasion de la Toscane pour y consommer sur place cette « boisson magique ». Plus tard avec l'occupation romaine la culture de la vigne s'étendit dans toute la province narbonnaise, dans la vallée du Rhône jusqu'aux portes de Lyon, puis en Aquitaine. A leur tour les romains se mirent à apprécier les vins gaulois, de qualité supérieure à ceux récoltés en Italie sur les Hautains. A l'aide de la navigation fluviale sur le Rhône les vins gagnèrent Rome, ainsi que ceux embarqués dans les petits ports du rivage méditerranéen. Puis au cours des siècles et grâce notamment aux religieux catholiques la vigne se répandit dans toutes les provinces. A la veille de la Révolution, en 1788, on estimait la superficie cultivée à 1.567.000 hectares, produisant 27 millions d'hectolitres. Au cours du XIXe siècle, les plantations augmentèrent en raison des facilités de transport que permettait l'établissement des lignes de chemin de fer. Le ravitaillement des grandes villes fut assuré par la création d'un important vignoble dans le Midi. En 1875, la superficie cultivée dépassait 2,4 millions d'hectares et la France produisit 83,8 millions d'hectolitres, record absolu qui ne fut jamais plus atteint depuis. La crise phyllox

    Full Text Available Le point de départ de cet article est la grande variabilité de la pollution nitrique diffuse de l’eau due à l’agriculture. Celle-ci dépend en particulier du climat, des types de sol et des systèmes de production agricole. Nos recherches réalisées de façon interdisciplinaire à partir de deux sites différents en France, montrent que cette hétérogénéité spatio-temporelle conditionne les pratiques agricoles mises en œuvre pour réduire la pollution au niveau de la norme admise. De ce fait, les pratiques les plus « coût-efficaces » diffèrent d’un territoire à l’autre, en fonction des caractéristiques locales. Ces résultats mettent donc en évidence une efficacité potentielle d’une territorialisation des politiques publiques. En théorie, de telles politiques sont considérées comme optimales par les économistes, car elles incitent les agents à moduler leurs efforts en fonction de la sensibilité du milieu. Mais, selon les études empiriques, cet avantage serait annulé par un coût élevé de mise en œuvre, de contrôle et de surveillance. Pour maintenir leur avantage sur des politiques uniformes, les politiques territorialisées devraient être mises en œuvre à un niveau spatial optimal. Un tel niveau devrait au minimum atteindre un compromis entre l’économie réalisée grâce à une modulation adaptée aux conditions locales et les sur-coûts dus à la décentralisation des solutions mises en œuvre. Cet article analyse la pertinence d’une prise en compte de ces spécificités par des politiques territorialisées. L’efficacité d’une régulation différenciée de la pollution nitrique est étudiée ici en évaluant l’importance de la variabilité spatiale des paramètres physiques et des coûts de la territorialisation.The paper starts with the wide variability of nonpoint water nitrogenous pollution generated by agriculture. This variability depends especially on climate, soil types and farming

    The diagnosis of lateral collateral ankle ligament trauma is based on patient history, clinical examination and clinical stress tests. If the clinical stress test is positive, stress radiography can be performed. There is, however, no consensus about the usefulness of stress radiography in acute ankle sprain, and in particular about the cut-off talar tilt angle beyond which a two-ligament rupture would be certain, ranging from 5 to 30 . Today, magnetic resonance imaging (MRI) is not used in this area, although it does allow controlled positioning of the foot and defined section visualization of injured lateral collateral ankle ligaments. In acute and chronic sinus tarsi injuries, MRI forms the established basis for diagnostic imaging, and can provide a definitive answer in most cases. MRI is also the method of choice for chronic posttraumatic pain with anterolateral impingement after rupture of the anterior talofibular ligament. Generally, for the evaluation of acute ankle injuries, MRI has developed to be the most important second-step procedure when projection radiology is non-diagnostic. (orig.) [German] Die Diagnose einer lateralen Bandverletzung nach einem Sprunggelenktrauma basiert auf der Anamnese, der klinischen Untersuchung und klinischen Stresstests. Bei positiven klinischen Stresstests kann eine Stressradiographie durchgefuehrt werden. Es gibt keine Uebereinstimmung hinsichtlich des Stellenwerts der Stressradiographie beim frischen Supinationstrauma des Sprunggelenks, insbesondere fuer den Winkel der Aufklappbarkeit bei einer Zweibandverletzung, der von 5 -30 reicht. Die MRT wird bei dieser Indikation zurzeit nur in Einzelfaellen benutzt, obwohl sie mit definierter Fusspositionierung und Ausrichtung der Untersuchungsebene eine ausgezeichnete Beurteilung der Sprunggelenkbaender erlaubt. Sie ist im besonderen Masse geeignet, akute und chronische Verletzungen des Sinus tarsi zu beurteilen. Bei chronischen Beschwerden nach Bandverletzung ist die MRT zur

    Full Text Available On voit ce que l’on apprend à voir. Trop longtemps, on a cru que la couleur des cités historiques portugaises était répartie entre un Nord de culture atlantique (où l’authenticité des matériaux naturels prédomine et un Sud méditerranéen favorisant la sensualité blanche (mortier et chaux ; les azulejos sont, eux, comme une rêverie du xixe siècle. Longtemps, on a résolu la difficulté de la présentation architecturale des monuments anciens au public en s’appuyant sur ce modèle simpliste. Aujourd’hui, la vérité apparaît différente. Partout, on découvre par strates des vestiges d’éléments décoratifs : sgraffites, trompe-l’œil, stucs, etc., et de la couleur. Le palais de Queluz – inspiré de Versailles comme nombre de palais d’Europe au xviiie siècle – est un exemple typique de cette incapacité de « regarder » les monuments. La découverte récente de vestiges d’un bleu « ciel » (bleu de smalt remet en question l’idée communément admise que ses façades avaient toujours été roses ou ocre jaune.We see what we learn to see. For many years, it was thought that the colour of the historical cities of Portugal could be divided into that of the Atlantic north, where the natural colours of materials predominate, and those of the Mediterranean south, favouring the white sensuality of mortar and whitewash; as for the azulejos, they were more often than not seen as a nineteenth-century fancy. The difficulties of presenting the architectural particularities of an old monument to the public were long resolved by referring to this over-simplistic model. Today, the truth appears to lie elsewhere. Vestiges of decorative elements such as sgraffito, trompe l’œil, stucco, and colour are being discovered, in strata, throughout the country. The Queluz Palace, inspired by Versailles like many other palaces in Europe in the eighteenth century, is a typical example of this inability to ‘see’ monuments

    Full Text Available Les travailleurs experts et novices présentent des caractéristiques différentes, particulièrement pour les éléments de placements/déplacements des pieds et de manœuvres effectuées avec les boîtes. Un examen biomécanique de ces éléments et de certaines stratégies contrastant les experts et les novices a mis en évidence leur potentiel pour une manutention plus sécuritaire. On note la réduction des chargements articulaires, surtout au dos, la réduction des asymétries du dos et les exigences moins grandes en travail mécanique. L’efficacité de stratégies d’experts et de novices fut ensuite évaluée, suite à un programme d’entraînement, par deux études indépendantes effectuées chez des travailleurs novices. On a d’abord étudié les effets de la pratique libre pour conclure qu’elle ne mène pas spontanément à un apprentissage de stratégies optimales. On a ensuite évalué un entraînement orienté sur l’observation de certaines stratégies contrastées propres à des experts et à des novices (placement/déplacement des pieds, manœuvres de boîtes et posture du dos, combinée à une pratique libre mais orientée sur une recherche de solutions optimales ; on a conclu que les novices soumis à cet entraînement adoptaient rapidement de nouvelles façons de manœuvrer les boîtes et de se placer qui apparaissent plus sécuritaires pour le travail mécanique et les efforts au dos. Il est donc recommandé d’inclure ces éléments dans les programmes d’entraînement et d’élaborer des programmes sur la base des connaissances des travailleurs et l’observation de leurs performances plutôt que sur la seule théorie.Expert and novice workers present different characteristics, particularly for aspects such as foot positioning/displacement and box maneuvers.

    OBJECTIVE To determine outcomes and complication rates of open reduction and cranial bone plate fixation of fractures involving the distal aspect of the radius and ulna in miniature- and toy-breed dogs. DESIGN Retrospective case series. ANIMALS 102 miniature- and toy-breed dogs (105 fractures) weighing ≤ 7 kg (15.4 lb) that had undergone open reduction and cranial bone plate fixation of a fracture involving the distal aspect of the radius and ulna from 2008 through 2015. PROCEDURES Medical records were reviewed and information extracted regarding dog and fracture characteristics, surgical variables, and follow-up examination data (including postoperative complications). Postoperative radiographs were examined for distal fragment size, implant placement, apposition, alignment, and healing stage. A long-term follow-up questionnaire was completed by telephone interview with dog owners at least 6 months after surgery. RESULTS Mean length of the distal bone fragment in all fractures was 19.2 mm, with a mean distal-to-total radial length ratio of 0.21. At last follow-up examination (typically 6 weeks after surgery), 97 (95%) dogs had no signs of lameness; minor lameness was identified in 5 (5%) dogs. Complications developed in 26 (25%) fractures (23 [22%] minor and 3 [3%] major complications). Sixty-eight of 71 (96%) owners rated the overall and long-term outcome as excellent and 3 (4%) as good; 68 of 71 (96%) dogs reportedly had no signs of residual lameness. CONCLUSIONS AND CLINICAL RELEVANCE Open reduction and cranial bone plate fixation for the treatment of radius-ulna fractures in miniature- and toy-breed dogs provided an excellent outcome with a low complication rate.

    2016-09-01

    Full Text Available The article considers language as the organization of the speech of any person in any situation, without which it is impossible to characterize the internal structure of the speech stream. Language is exactly a system of guidelines necessary for the activity in the social world. Communication is primarily nothing but as a way of making one or another correction in the image of the interlocutor’s world. In order for a language to serve as a means of communication, it must have a single or a similar understanding of reality behind it. Conversely, the unity of understanding the reality and the unity of coherence presuppose the possibility of adequate communication. A mandatory component of communication is the communicative act, that is, the act of sharing information between people. The speech, i.e. the natural sound language is an important means of conveying information that defines this aspect of the communication process as verbal communication. The idea of dialogue as the space, in which the exchange of information takes place, is defined as initial. Essentially, it is the dialogue that in this case acts as the backbone principle in dealing with problems of language. It is here that the essence of social and psychological transition to the analysis of communication is most visibly concentrated. An individual essentially "lives" in the world of Another person’s worlds, and studying the words of this person, he or she studies the "world" of Another person. Thus, the dialogue is not merely the interaction (verbal with another person, but, ultimately, the interaction with the world of culture.

    Full Text Available Cet article tente de classer les apports d’Internet à l’enseignement/apprentissage des langues en partant de l’approche centrée sur la tâche. Les exemples sont empruntés au FLE. L’unité classificatoire, appelée "ressource", n’est pas constituée simplement de ce que l’on trouve sur Internet (contenus des "pages" et sites, canaux de communication mais cherche aussi à prendre en compte, en les distinguant, l’activité de l’enseignant et celle de l’apprenant. Selon que l’on considère l’une ou l’autre des deux facettes d’Internet, l’information ou la communication, ressortent alors deux notions : concernant la recherche d’informations, on considère qu’il est fondamental que celle-ci soit guidée par des tâches ; concernant la communication, c’est la notion de projet qui est évoquée.This paper attempts to classify the contribution of the Internet to language teaching and learning. The approach is task-oriented and the examples use French as a Foreign Language. It is shown that the definition of a classifying unit, or "resource", should take account not only of the contents of the Internet (Web Pages, Web sites and communication tools, but should also consider what the teacher or learner are to do with these resources. From both aspects of the Internet, information and communication, arise two important concepts, those of task and project. The best way for the teacher to guide the search of information consists in giving students a task ; designing projects will avoid ’empty’ communication.

    The authors first review the characteristics of uraninite-pitchblende, as deduced of present literature. They set apart from typical pitchblende a black oxide aspect, which probably corresponds to neo-formations, and a 'para-pitchblende' aspect, which they relate to deep sur-oxidation of normal pitchblende. They insist on the easy replacement of pitchblende by silica. and give indications as to changes in vein stones (fluorite, quartz, etc...). A detailed study of paragenesis and successions in french uranium districts follows (including discussion of uranium of uranium-bearing coals). The authors attempt to classify french pitchblende veins. They are chiefly epithermal and poor in satellite ores. Three types of deposits are identified: massive - pitchblende type, silica type, fluorite type. These deposits, as those of Portugal, are included in granite, Central-European peri-batholitic types where uranium associates which Ni, Co, Bi and Ag, are in France both rare and poor. Finally, the authors attempt to bring out in the european Hercynian area a particular distribution of paragenetic types. (authors) [French] Les auteurs recapitulent d'abord les caracteres et les occurences de l'uraninite - pechblende, tels qu'ils peuvent etre degages de l'actuelle bibliographie. Ils exposent ensuite les faits qui du point de vue mineralogique seulement ressortent de l'etude mineralogique et chalcographique des pechblendes francaises et de leurs satellites. Ils distinguent de la pechblende-type un facies oxyde noir; correspondant probablement a une neoformation, et un facies parapechblende, qui est rapporte a une sur oxydation hypogene de la pechblende proprement dite. Ils insistent sur le facile remaniement de la pechblende par la slice; et donnent quelques precisions sur les modifications des gangues (fluorine, quartz, etc...).

Après la chute de l'empire romain et les invasions des Awares, on doit à Charlemagne le renouveau de la culture de la vigne, notamment dans la Wachau, en Basse- Autriche. Puis plus tard, à chaque avance de la colonisation, les vignes se répandirent sur les bords du Danube et dans les vallées latérales, l'extension étant favorisée par les communautés religieuses catholiques qui devinrent propriétaires de grands vignobles. La navigation sur le fleuve fut également un facteur favorable pour la culture de la vigne. Au XVIe siècle, apogée des cultures, le vin se vendait jusqu'en Pologne et dans les Etats Baltes.

    This document presents the results of a study performed by CEPN for INRETS upon request of the Department of Dangerous substances of the Ministry of Transport and department of Isere. The objective is risk analysis related to transport of dangerous substances on the part of road known as 'pilot route', which crosses the city and the valley of Isere at Point de Claix. First estimation of traffic was done based on counting the traffic especially done for the purpose of the study and data concerning economic activity of the region. Annual traffic amounts to 30 to 50 000 vehicles transporting dangerous substances along this route. Contrary to the usual data in France, petroleum products amount to at least half of the traffic, the second half are toxic liquids and corrosion agents. Liquid hydrocarbons (70 veh/day), other inflammable products (20 veh/day), GPLs (10 veh/day) and caustic soda (30 veh/day) are transported according to this study. Traffic has been estimated for other products like chlorine (0.5 veh/day), ammonia (1 veh/day) or gaseous hydrochloric acid (1 veh/day), which are less frequent but more dangerous. Before estimating the risk, it was necessary to identify the possible impacts. It is evident that human health (death or injuries) is the objective, factors less defined than environmental damage or economic losses. Level of analysis was then very different dependent on the cases: quantification taken for mortality, approach semi-quantificative for pollution effects, and identification of economic impacts. This difference is explained by the fact that for the first case complete methodology exists for many years, and for the latter two cases it is still necessary to formulate appropriate methodologies. In the frame of this analysis, it was shown that it is difficult to establish precise hierarchy of protection options. On one hand, study included a methodology aspect for taking into account pollution impacts, and on the other hand it is necessary to

    The research project was started with the objective of developing the essential geological-technical-technological parts of the utilisation of highly-mineralised thermal waters for heating. It is based on the findings from the drilling and testing of 29 deep geothermal wells, the erection and operation of Geothermal Heating Stations in Northeast Germany until 1990. The operation of the Waren (Mueritz) and Neubrandenburg Geothermal Heating Stations including their modernisation and the solution of problems which occurred sometimes give proof of the principal technical-technological implementability of thermal water utilisation for energetic purposes. Matter of concern is the recirculation of the thermal water after being used for balneological purposes to the main flow of water used for energetic purposes without affecting subsequent reinjection. The conditioning of the thermal water before and after use for bathing and balneo-therapeutic purposes is another problrm. The essential results are presented here. (orig.)

    Full Text Available Information is necessary for life because everything can not be done properly in the absence of information. The security problem is one of the most crucial aspects of a file containing sensitive information, for example, medical record files. Often, the file owner, designer, and manager of the information systems pay less attention to the security issues. One way to anticipate this is by using a cryptographic method, which is the science and art to keep the message security. This study aimed to evaluate the performance analysis and building a security system prototype of medical record files using the 4DES algorithm. The 4DES algorithm is a variant of the 3DES algorithm that is more robust and capable of protecting information properly. The 4DES security system has four keys; each key has a key length of 64 bits so that the total length of four keys is 256 bits and K1≠K2≠K3≠K4. The encrypted / decrypted files (Word, Excel, and Image  using an external key of minimum eight characters (64 bits. During encryption, there was an addition of padding bytes in each of data block size to minimalized attack from the attacker using a CBC operation mode process. Results showed that the processing speed of the encrypted files using the 4DES was 1 second faster than that of using the 3DES algorithm. Also, the 4DES algorithm has superiority regarding of file safety, which has time enduring 3.45 x1056years longer to brute force attack technique which able to discover text file and the secret key.

    Artificially induced calcite precipitation combined with deep water aeration has been tested as a possible technology for lake restoration. A pilot equipment for whole lake experiments has been developed for the restoration of the Lake Schmaler Luzin on the basis of enclosure experiments. The hypolimnetic calcite precipitation was induced by hypolimnetic addition of Ca(OH){sub 2}. In 1996 the first experiments were aimed at checking the conditions for artificially induced hypolimnetic calcite precipitation and their effectiveness on phosphorus elimination. 140 t Ca(OH){sub 2} and 416 000 m{sup 3} air were added in the hypolimnion during two cycles of these experiments, each lasting one month. This led to an increase of the pH value in the hypolimnion from 7.2 to 9.1, above the sediment (2-3 cm) from 7.2 to 8.2 and in the upper layers of sediments from 7.4 to 8.6. The chemical equilibrium was shifted towards the calcite and we observed hypolimnetic calcite precipitations. In 1996 the hypolimnetic aeration was performed with the aim of homogenisation of the hypolimnion. As expected the amount of added air was not enough to make the whole hypolimnion aerobic during the summer stagnation. The reduction of the total and dissolved phosphorus concentration in the hypolimnion and at the sediment-water interface in comparison to the values of the year before indicated the occurence of phosphorus coprecipitation with calcite. The concentration of the soluble reactive phosphorus above the sediment decreased from 0.31 mgl{sup -1} in 1995 (26.07.) to 0.04 mgl{sup -1} in 1996 (01.08.). (orig.)

    Full Text Available Un essai de bilan des effets écologiques des introductions d'espèces est présenté à partir des exposés des orateurs de ce colloque et de la bibliographie. L'aspect inéluctable de la dispersion des espèces au cours du temps et l'efficacité toute relative des barrières intracontinentales qui s'y opposent sont soulignés. Les mécanismes en cause - vagilité et fécondité des espèces introduites, efficacité des barrières, structure des réseaux trophiques récepteurs, degré de saturation de leurs niches écologiques - sont étudiés en regard du fonctionnement des hydrosystèmes, montrant la complexité du problème. Des effets écologiques très variés sont décrits, dont beaucoup sont non intentionnels et inattendus ; un exemple bibliographique est développé, mettant en évidence la diversité des effets de la même introduction selon le milieu récepteur. Il en ressort la nécessité préliminaire absolue d'examiner à la fois la biologie des espèces à introduire et le fonctionnement de l'écosystème récepteur. Un principe de précaution est préconisé face à toute introduction volontaire, et une réglementation sévère et efficace face aux introductions involontaires. Le besoin d'une permanence d'agents de terrain pour établir une veille écologique est souligné. Face au manque de données objectives, des recherches scientifiques sur les effets écologiques des introductions passées ou possibles doivent être initiées ou poursuivies dans un cadre écosystémique, impliquant au minimum un suivi des écosystèmes risquant d'être colonisés.

    This thesis present an analysis of qualitative interviews with experts in the field of climate research in which the relation among science, policy and public is discussed. To begin, an overview of the methods and results of climate science is presented. Following, elements of the discourse among science, policy and public are presented in a manner that demonstrates the different ways to look at the problem of anthropogenic climate change. Subsequently, approaches of the sociology of science are introduced in which science is examined as a social process. Here the question is raised up to what extent climate research has taken a problem oriented perspective in which social and political criteria in the treatment of actual risks of global change are taken into account. The results of the analysis indicate that uncertainties in science led to different perspectives regarding the risks of anthropogenic climate change. In this way scientific knowledge itself becomes problematic. Communication of scientific results to policy and public poses a process which is stamped by individual values and preferences. This suggests the possibility that recognition of theories is increasingly determined by extra scientific criteria like resonance in the media and possibility of connection for political measures. (orig.) [German] In dieser Arbeit wird eine Analyse qualitativer Interviews mit Klimaforschern vorgestellt, in denen das Verhaeltnis von Wissenschaft, Politik und Oeffentlichkeit diskutiert wird.
