Apport des analyses chimiques multi technique à la compréhension du comportement des éléments traces dans les filières sidérurgiques anciennes. Application aux études de provenance et à la distinction des procédés. Le cas du Pays de Bray normand.

Desaulty, Anne-Marie 24 September 2008 (has links) (PDF)
Afin de déterminer la provenance et le procédé d'élaboration (procédé direct, indirect) d'objet en fer archéologiques, cette étude a cherché à préciser le comportement des éléments traces dans les filières sidérurgiques anciennes. Pour caractériser ce comportement il est nécessaire d'étudier les déchets et produits issus de l'ensemble des deux filières. Rappelons qu'à l'issue de ces procédés anciens, l'objet a la particularité de contenir une partie de scorie, le déchet de la réduction (procédé direct) ou de l'affinage (procédé indirect) sous forme d'inclusion. La taille de ces inclusions et d'une manière générale l'hétérogénéité des échantillons archéologiques ont nécessité pour déterminer leur composition en éléments majeurs et traces d'employer une approche multi échelle (analyses macroscopique, microscopique) requérant l'utilisation d'un grand nombre de techniques d'analyse (EDS, ICP-MS, INAA, LA-ICP-MS). Le corpus étudié est composé d'échantillons provenant de sites archéologiques du Pays de Bray et de réductions expérimentales effectuées à partir de minerai brayon. Celui-ci a également été complété par des spécimens provenant d'autres régions et des données de la base Palsid ont également été utilisées. L'étude de ces échantillons a montré que les scories et donc les inclusions des objets issues de la réduction directe contiennent la plupart des éléments traces présents initialement dans le minerai, alors que les inclusions et scories indirectes sont issues de l'affinage d'une fonte considérablement épurée. Ce sont donc les ordres de grandeur des teneurs de ces éléments (La, Ce, Sm, U...) dans les inclusions des objets, qui permettent de distinguer les deux procédés. Une méthodologie afin de caractériser la signature chimique d'une région géologique a également été établie. La « signature métal » permet de pister le minerai utilisé dans le métal de l'objet (Co/Ni, As/Sb). La «signature déchet » valable uniquement pour des échantillons issus du procédé direct permet de relier les scories, et les inclusions de l'objet fini aux minerais employés (teneurs absolues en éléments majeurs et traces, Si/Al, K/Ca, Mg/Al, K/Al, Sm/Th, Th/U, La/Yb, Y/Yb, Hf/Nb, Eu/Sm, Cs/Rb, Th/Sc). Les « signatures déchet et métal » du Pays de Bray ont été comparées à celles d'autres régions afin de tester leur pouvoir de discrimination. Il apparaît que l'utilisation de ces signatures permet de nettement séparer des échantillons d'origines différentes. Il est ainsi possible d'appliquer cette méthodologie à une problématique historique précise : la détermination des échanges commerciaux entre Rouen et le Pays de Bray au Moyen Âge. Dans ce but des fers de construction des églises rouennaises ont été étudiés. Les « signatures déchets » de ces objets sont très variables d'un échantillon à l'autre et différentes de celle du Pays de Bray. Ces résultats permettent de réfuter l'hypothèse d'une arrivée massive de fer brayon à Rouen au Moyen Âge et plaident pour un approvisionnement des chantiers de la ville fortement lié aux opportunités économiques et politiques, expliquant ainsi la très grande diversité des signatures.

Problematiska faktorer för krishantering vid olika ledarskapsnivåer i verkliga krissituationer / Problematic Factors for Crisis Management in Various Leadership Levels in Real Crisis Situations

Markbåge, Sebastian January 2006 (has links)
<p>Denna kvalitativa studie undersöker ledarskapsfaktorer hos räddningschefer och kommunalråd i svenska kommuner som varit med om betydelsefulla krissituationer. Intervjudata ifrån två tidigare studier användes. Räddningschefer representerade det direkta ledarskapet medan kommunalråden representerade det indirekta ledarskapet. Analysen genomfördes huvudsakligen enligt Grounded Theory. Två dimensioner identifierades. Den kronologiska dimensionen bestod av faktorer före, under och efter själva krishändelsen. Organisations-dimensionen bestod av faktorer inom den intervjuades egen organisation, utanför den egna organisationen och mellan organisationer. Den senare dimensionen kunde förklaras av att båda ledargrupperna klassificerats som exekutivt ledarskap. Överlag ansåg båda yrkesgrupperna att informationsflöde och samverkan var problematiska faktorer. Yrkesgrupperna var inte matchade på viktiga variabler vilket försvårade analys av skillnaden mellan det indirekta och direkta ledarskapet.</p> / <p>This qualitative thesis studies leadership factors in rescue commanders and mayors in Swedish municipalities that have been affected by important crisis situations. Interview data from two earlier studies was used. Rescue commanders represented the direct leadership while the mayors represented the indirect leadership. The analysis was mainly carried out according to Grounded Theory. Two dimensions was identified. The chronological dimension contained factors before, during and after the crisis event. The organisation dimension contained factors within the interviewee’s own organisation, outside the own organisation and between organisations. The later dimension could be explained by attributing the qualities of executive leadership to both of the groups. Both groups did find information flow and cooperation to be problematic factors overall. The groups weren’t matched on important variables which made analysis of differences in the direct and indirect leadership difficult.</p>

On the Use of <sup>76</sup>Br-labelled Monoclonal Antibodies for PET : Preclinical Evaluation of Halogenated Antibodies for Diagnosis and Treatment of Cancer

Höglund, Johanna January 2002 (has links)
<p>Radioactive substances are used <i>in vivo</i> to localize and characterize malignant tumours, generally by scintigraphic methods. In this context positron emission tomography (PET) in combination with radiolabelled monoclonal antibodies (mAbs) may provide a sensitive and specific method for detection of cancer. Individual dose calculations, based on such PET measurements, may be carried out to predict the possible use of mAbs labelled with therapeutic nuclides. The positron emitter <sup>76</sup>Br, with a half-life of 16 h, is a well-suited candidate for radiolabelling and PET imaging. One drawback of radiobromine is that bromide, the ultimate catabolite after degradation of brominated mAb, is only tardily excreted from the body and is evenly distributed throughout the extracellular space, thereby increasing the background radioactivity. The aim of this work was to produce <sup>76</sup>Br-mAb preparations with high accumulation and retention in tumour tissue together with a quick clearance of <sup>76</sup>Br-labelled catabolites. Furthermore, the possibility to use brominated or iodinated mAbs in combination with PET to predict <sup>211</sup>At-mAb dosimetry was evaluated.</p><p>Monoclonal Abs directed against colorectal cancer were labelled with <sup>76</sup>Br using the direct Chloramine-T-method or indirectly by labelling the precursor molecule N-succinimidyl para-(tri-methylstannyl) benzoate with <sup>76</sup>Br, which was subsequently conjugated to the mAbs. Monoclonal Ab A33 labelled with <sup>76</sup>Br using the two labelling protocols was characterized in vitro and in vivo in a rat tumour xenograft model. The mAb A33 was also labelled with <sup>125</sup>I for comparison. In addition, mAb A33 was labelled with <sup>211</sup>At, <sup>125</sup>I and <sup>76</sup>Br using the indirect labelling protocol and the mAb pharmacokinetics was studied in normal rats in order to estimate if data from brominated or iodinated mAb could be used for dosimetry of <sup>211</sup>At in healthy organs and tissue.</p><p>In conclusion, both direct and indirect labelling resulted in high yields and mAbs with preserved immunoreactivity. <i>In vivo</i> characterization of <sup>76</sup>Br-brominated mAb A33 showed that the indirect labelling method makes <sup>76</sup>Br-brominated mAb A33 a promising candidate for tumour imaging with PET due to the faster excretion of radiolabelled catabolites compared with direct bromination. Finally, mAb A33 labelled with <sup>76</sup>Br and <sup>124/125</sup>I can be used to predict the <sup>211</sup>At dose of astatinated mAb A33 in most organs given that a correction factor is applied for organs with varying uptake.</p>

Saisir l'insaisissable : les formes et les traductions du discours indirect libre dans des romans suédois et français

Jansson, Kristina January 2006 (has links)
Abstract Jansson, Kristina, 2006. Saisir l’insaisissable. Les formes et les traductions du discours indirect libre dans des romans suédois et français. Acta Wexionensia nr 86/2006. ISSN: XXXX-XXXX, ISBN: 91-7636-499-2. Written in French. The purpose of this study is to explore the possible forms and translations of free indirect discourse (discours indirect libre) in some French and Swedish novels written between 1880 and 1920. For the study, two corpora containing free indirect discourse (FID) were established: one with Swedish FID from some 40 novels written by August Strindberg, Selma Lagerlöf, Hjalmar Bergman and Hjalmar Söderberg and one with FID from one novel each by Émile Zola and Guy de Maupassant, and two by Anatole France. These two corpora were compared in order to examine the influence of grammar, translational norms and individual translators on the final result. Another purpose was to compare the forms of FID in French and Swedish since they differ somewhat. The biggest difference seems to be that Swedish has a greater aptitude for mixing elements from several levels of narration. The study itself is divided in two parts. The first one explores the individual characteristics that create FID, their forms and their translation. There seems to be no syntactical difference in the treatment of personal pronouns, the alterations seem to be the result of a change made by the translators. The treatment of verb tenses and adverbials differs somewhat. One of the characteristics of FID is that it combines deictic adverbials focalised through the characters with verb tenses focalised through the narrator. French adverbials, above all deictic time adverbials, are restricted in that they cannot occur juxtaposed to all verb tenses, whereas Swedish is free to do so to a higher extent, a difference that influences the translation. Verb tenses are also a problem in that the French language has two, passé simple and imparfait, the former rare in FID, where Swedish only has preteritum. Other characteristics of FID, such as repetitions, hesitations, the use of proper names etc. cause fewer problems in translation. The second part of the analysis handles the destiny of all of FID in translation. 91% of the French FID remain in the Swedish translations, whereas 82% remain in the French translations, numbers that show that there is a difference between the languages. This final part also analyses the reasons behind the transformation of FID into other forms of speech rendering in translation, including the translator’s influence over transformations that can be compared to that of the narrator over speech rendering.
