Analyse du rôle de l'IFREMER dans l'instruction du dossier Salmor

This report describes the contribution made by IFREMER in the various stages of installation of a new salmon culture in barge's tanks moored in Morlaix Bay. Tacking into account the opposition to this project, including direct criticism of the role of IFREMER, a considerable effort is made to provide detailed environmental impact data to the appropriate Government office

Les regards traîtres (recueil de nouvelles), suivi de Le motif du mauvais œil dans les nouvelles fantastiques de Bertrand Bergeron (essai)

Ce mémoire est constitué de trois volets. Tout d'abord, on y présente une création littéraire, court recueil de nouvelles intitulé Les regards traîtres. Celui-ci est suivi d'un essai portant sur le sous-genre fantastique, qui dans sa forme canonique offre une place prépondérante aux motifs littéraires. Suit une courte revue du motif du mauvais œil et une analyse détaillée d'un corpus de nouvelles de l'auteur québécois Bertrand Bergeron. Celles-ci ont été sélectionnées parmi les ouvrages de l'auteur afin de mettre en lumière la transformation et la refonte du motif littéraire du mauvais œil dans l'écriture néo-fantastique contemporaine. Enfin, le dernier volet consiste en un retour réflexif ayant pour but de démontrer les mécanismes à l’œuvre dans ma création afin d'illustrer les questions étudiés dans le mémoire. Il s'agit donc ici, tant dans l'étude des théories et dans celle du corpus de Bergeron que dans la création inédite, d'explorer non seulement les constituants du sous-genre fantastique et la présence du motif à l'étude, mais bien de cerner l'actualisation de ce motif dans l’œuvre de Bergeron, d'en démontrer la forme, renouvelée ou pas, et finalement de procéder à la mise en scène dans mes propres nouvelles de cette actualisation. Les résultats obtenus à la suite de ces exercices démontrent que le motif littéraire du mauvais œil, bien qu'utilisé de manière différente, subsiste dans une forme revisitée sous la plume d'un auteur de néo-fantastique tel que Bertrand Bergeron. Les nouvelles du recueil Les regards traîtres concrétisent, quant à elles, la possibilité de faire vivre ce motif, voire d'en faire le moteur de mes intrigues.

La representación del poder y los discursos en la pintura. Las transformaciones de la pintura francesa, 1680-1730

Esta tesis se ha construido a partir del método arqueológico que hemos establecido, a su vez, a partir de la obra de M. Foucault La Arqueología del Saber, así como de sus seminarios del Collège de France. Desde ella hemos definido una alternativa metodológica para estudiar el arte, respecto a las otras propuestas metodologías tradicionales de la Historia del Arte; centrándonos principalmente en los discursos producidos por el saber artístico. A partir de los problemas que encierra la Historia, y por consiguiente la Historia del Arte, como hemos puesto de manifiesto al analizar los términos barroco y rococó, nos hemos alejado de las diversas corrientes historiográficas que definen la Historia del Arte, determinadas por los problemas de la Historia y de la Forma, proponiendo una nueva aproximación al análisis del arte a través de la Arqueología del Saber de M. Foucault, que -sin duda- ha condicionado la forma de nuestro trabajo. Esto nos ha conducido a centrarnos principalmente en los discursos artísticos, esto es, en los discursos producidos por el propio saber artístico, trabajando sobre los textos teóricos, las conferencias, los panfletos o libelos de las polémicas artísticas, sobre los poemas elogiosos hacia determinadas obras o sobre las descripciones periodísticas. Hemos intentado estudiar en profundidad, por tanto, todo ese mundo de discursos producidos desde y por el arte, que constituirán en su conjunto un saber artístico, dejando en un segundo plano las formas artísticas. Esta elección de una metodología arqueológica ha condicionado por tanto la forma de nuestro trabajo, pues éste no ha intentado reconstruir el proceso artístico o creativo de una obra, ni tampoco las vicisitudes por las que ha pasado una obra concreta. Tampoco hemos pretendido desde la obra, entendida como evento o acontecimiento –al modo que hace la Historia- analizar la sociedad de la época; como si el arte fuera el reflejo de una Verdad histórica o de un espíritu de su tiempo. Nuestro objetivo ha consistido en intentar comprender en qué medida el arte, en tanto que saber y conjunto de discursos, se ve afectado por los cambios en la verdad-poder que suceden en su época. Pero estas transformaciones han sido estudiadas no desde la obra en sí -como tradicionalmente se ha hecho- sino desde los discursos arriba señalados, pues es más fácil analizar las formas de actuación del poder a través de los discursos que genera que a través de las formas artísticas, cuyos “comportamientos” no son tan fácilmente cognoscibles desde la palabra, a la que tiende a expulsar, como bien señaló Platón en su República...

Toxoplasma gondii Isolates From Free-Range Chickens From the Northeast Region of Brazil

The prevalence of Toxoplasma gondii in free-ranging chickens is a good indicator of the prevalence of 7: gondii oocysts in the soil because chickens feed from the ground. The prevalence of T. gonulii in 152 free-range chickens (Gallus domesticus) from 22 municipalities in 7 northeastern states (Pernambuco, Rio Grande do Norte, Maranh5o, Bahia, Ceara, Sergipe, and Alagoas) of Brazil was determined. Antibodies to T. gondii were assayed by the modified agglutination test (MAT); 81 (53.3 %) chickens had titers of 1:5 in 26, 1:10 in 9, 1:20 in 4, 1:40 in 1, 1:80 in 6, 1:160 in 6, 1:320 in 13, 1:640 in 6, 1:1,280 in 3, 1:2,560 in 6, and 1:5,120 or higher in I. Hearts and brains of 81 seropositive chickens were bioassayed individually in mice. Toxoplasma gondii was isolated from 23 chickens with MAT titers of 1:5 or higher; the isolates were designated TgCKBr165-187. Five isolates killed all infected mice. Results indicate widespread contamination of rural environment in Brazil with T. gondii oocysts.

[O/Fe] ESTIMATES FOR CARBON-ENHANCED METAL-POOR STARS FROM NEAR-INFRARED SPECTROSCOPY

We report on oxygen abundances determined from medium-resolution near-infrared spectroscopy for a sample of 57 carbon-enhanced metal-poor (CEMP) stars selected from the Hamburg/ESO Survey. The majority of our program stars exhibit oxygen-to-iron ratios in the range +0.5 < [O/Fe]< + 2.0. The [O/Fe] values for this sample are statistically compared to available high-resolution estimates for known CEMP stars as well as to high-resolution estimates for a set of carbon-normal metal-poor stars. Carbon, nitrogen, and oxygen abundance patterns for a sub-sample of these stars are compared to yield predictions for very metal-poor asymptotic giant branch (AGB) abundances in the recent literature. We find that the majority of our sample exhibit patterns that are consistent with previously studied CEMP stars having s-process-element enhancements and thus have very likely been polluted by carbon- and oxygen-enhanced material transferred from a metal-poor AGB companion.

Phylogenetic nomenclature and evolution of mannose-binding lectin (MBL2) haplotypes

Background: Polymorphisms of the mannose-binding lectin gene (MBL2) affect the concentration and functional efficiency of the protein. We recently used haplotype-specific sequencing to identify 23 MBL2 haplotypes, associated with enhanced susceptibility to several diseases. Results: In this work, we applied the same method in 288 and 470 chromosomes from Gabonese and European adults, respectively, and found three new haplotypes in the last group. We propose a phylogenetic nomenclature to standardize MBL2 studies and found two major phylogenetic branches due to six strongly linked polymorphisms associated with high MBL production. They presented high Fst values and were imbedded in regions with high nucleotide diversity and significant Tajima's D values. Compared to others using small sample sizes and unphased genotypic data, we found differences in haplotyping, frequency estimation, Fu and Li's D* and Fst results. Conclusion: Using extensive testing for selective neutrality, we confirmed that stochastic evolutionary factors have had a major role in shaping this polymorphic gene worldwide.

Offline Detection, Identification, and Correction of Branch Parameter Errors Based on Several Measurement Snapshots

This paper proposes a three-stage offline approach to detect, identify, and correct series and shunt branch parameter errors. In Stage 1 the branches suspected of having parameter errors are identified through an Identification Index (II). The II of a branch is the ratio between the number of measurements adjacent to that branch, whose normalized residuals are higher than a specified threshold value, and the total number of measurements adjacent to that branch. Using several measurement snapshots, in Stage 2 the suspicious parameters are estimated, in a simultaneous multiple-state-and-parameter estimation, via an augmented state and parameter estimator which increases the V - theta state vector for the inclusion of suspicious parameters. Stage 3 enables the validation of the estimation obtained in Stage 2, and is performed via a conventional weighted least squares estimator. Several simulation results (with IEEE bus systems) have demonstrated the reliability of the proposed approach to deal with single and multiple parameter errors in adjacent and non-adjacent branches, as well as in parallel transmission lines with series compensation. Finally the proposed approach is confirmed on tests performed on the Hydro-Quebec TransEnergie network.

Sand bioconsolidation through the precipitation of calcium carbonate by two ureolytic bacteria

Two ureolytic strains, B. sphaericus LMG 22257 and Bacillus sp (I-001), were tested for their ability to consolidate sand by submitting them to two days` treatment using 10(7) viable cell concentrations of inocula and medium precipitation with calcium ions. The results showed that B. sphaericus LMG 22257 induced greater calcium carbonate formation. Both strains produced calcite and were able to consolidate sand. Tensile strength of consolidated sand was not a function of the amount of precipitated CaCO(3) but a linear function of the ratio bioconsolidation index (BC) defined as the ratio of CaCO(3) volume to initial sand porosity. A simple model to estimate the engineering benefits of consolidation is proposed. (C) 2011 Elsevier B.V. All rights reserved.

Carbon and Nitrogen Dynamics in an Oxisol as Affected by Liming and Crop Residues under No-Till

The short-term effects of surface lime application and black oat (Avena strigosa Schreb.) residues, with or without N fertilization, were evaluated in a long-term no-till (NT) system on a sandy clay loam, a kaolinitic, thermic Typic Hapludox from the state of Parana, Brazil. The main plot treatments were: control and dolomitic lime applied on soil surface at 8 Mg ha(-1). Three treatments with crop residues were evaluated on the subplots: (i) fallow, (ii) black oat residues, and (iii) black oat residues aft er N fertilization at 180 kg ha(-1). Black oat dry biomass was not affected by the treatments during 3 yr. Surface liming increased soil pH, microbial biomass, microbial activity, and bacterial/fungal ratio at the soil surface (0-5 cm), resulting in increased amino acid turnover, water-soluble humic substances formation, and N mineralization and nitrification. While the application of black oat did increase the soil pH, overall it had much less effect on soil biological processes and C and N pools than did lime. We concluded that black oat cannot replace the need for lime to optimize crop production in these tropical NT systems. In the long term, however, black oat should aid in the amelioration of acidity and replenishment of soil organic C pools and should help reduce erosion. Overall, this study suggests that overapplication of inorganic fertilizer N may occur in some tropical NT systems. Further experiments are required in NT systems to investigate the use of slow-release N fertilizers in combination with lime and black oat as a mechanism to reduce acidification and promote sustainability.

Self-Organizing Maps as a New Tool for Classification of Plants at Lower Hierarchical Levels

A chemotaxonomic analysis is described of a database containing various types of compounds from the Heliantheae tribe (Asteraceae) using Self-Organizing Maps (SOM). The numbers of occurrences of 9 chemical classes in different taxa of the tribe were used as variables. The study shows that SOM applied to chemical data can contribute to differentiate genera, subtribes, and groups of subtribes (subtribe branches), as well as to tribal and subtribal classifications of Heliantheae, exhibiting a high hit percentage comparable to that of an expert performance, and in agreement with the previous tribe classification proposed by Stuessy.
