Sur la migration des éléments par thermodiffusion. Etat et perspectives d'un modèle géochimique
No full textIn the lithosphère, particularly in great geothermal activity zones, there exist possibilities of quasi permanent thermal diffusion natural convection couplage which is able to develop a thermogravitational effect. The study of concrete cases requires a good knowledge of physical parameters introduced in thermogravitational-effect theoretical relations, as well as hydrothermal convective circuits, the nature of solutions, and local thermal gradient values.
A thermogravitational schematic model has been developed and applied to Salton-Sea geothermal system. This model is supported by some simple geometric dispositions fitted to convective cell development and underlining the effect of geometric and thermal parameters on estimate concentration extent. This model provides the rough estimate concentrations of brines, like those observed in-situ, in agreement with most geochemical and geological local contingencies. The refining of this model will be linked to a better knowledge of the organization and stability of convective circuits in underground fluids.Il existe dans la lithosphère, particulièrement dans des zones à forte activité géothermique, des possibilités de couplage quasi-permanent entre thermodiffusion et convection naturelle pouvant aboutir au développement d'un effet thermogravitationnel. L'étude de cas concrets nécessite une bonne connaissance des paramètres physiques intervenant dans les relations décrivant l'effet thermogravitationnel, des circuits convectifs suivis par les solutions hydrothermales, de la nature de celles-ci, et de la valeur des gradients thermiques locaux.
Un modèle schématique d'effet thermogravitationnel appliqué au géotherme de Salton-Sea a été développé. Il s'appuie sur quelques dispositions géométriques simples favorables au développement de cellules convectives adaptées et mettant en évidence le rôle des paramètres géométriques et thermiques sur l'ampleur des concentrations prévisibles. Ce modèle fournit l'ordre de grandeur de la concentration des saumures, observées in situ, en accord avec l'essentiel des contingences géochimiques et géologiques locales. L'affinement de cette modélisation sera lié à une meilleure connaissance de l'organisation et de la stabilité des circuits convectifs des fluides souterrains.Costesèque Pierre.

Is There Market Power in the French Comte Cheese Market?
No full textAn NEIO approach is used to measure seller market power in the French Comté cheese market, characterised by government-approved supply control. The estimation is performed on quarterly data at the wholesale stage over the period 1985-2005. Three different elasticity shifters are included in the demand specification, and the supply equation accounts for the existence of the European dairy quota policy. The market power estimate is small and statistically insignificant. Monopoly is rejected, as well as weak forms of Cournot oligopoly. Results appear to be robust to the choice of functional form, and suggest little effect of the supply control scheme on consumer prices.Supply control, NEIO, protected designation of origin, Marketing,
The aesthetics of Pierre Boulez
No full textTo enable the reader to find references as quickly and easily as possible, I have grouped all references together in the bibliography in alphabetical order. Texts by the same author are distinguished first by year and second, if there are several texts from the same year, by letter. Interviews and writing collaborations (including published correspondence) involving Boulez are also ordered alphabetically. The year given at the beginning of each bibliographical entry is, in the majority of cases, the year in which the text was first published (not necessarily the year of the edition cited). For all writings written by Boulez, I have provided the original title under which the text in question was first published (usually in French). Many articles have subsequently been translated into English and therefore I have decided to provide page references for both versions. For all texts by writers other than Boulez, I have cited the version of the text I have used. Wherever possible, I have cited the existing English translations of texts originally written in French. However, on many occasions I have considered it necessary to make alterations to the published translations. This is particularly applicable to Boulez on Music Today (1971) and Orientations (1986), both of which display an often heavy-handed and rather inaccurate approach to the task of translating specific concepts employed by Boulez. In contrast. Stocktakings of an Apprenticeship (1991) has required only occasional minor amendments. All changes to the published English translations are acknowledged in the corresponding footnote. None of the material m this thesis has previously been submitted for a degree in this or any other University. The copyright of this thesis rests with the author. No quotation from it should be published without prior written consent and information from it should be acknowledged.

Migrations sélectives de solutions de terres rares par effet thermogravitationnel en milieu poreux
No full textRare earth spectra of ores and rocks, used as guides to understand the origin of mineralizing hydrothermal solutions can have been modified by thermal diffusion phenomena. This experimental study shows thermogravitational behaviour of simple lanthanide solutions (La(NO3)3 and Ce(NO3)3) in packed columns. Each of these salts seems to possess particularly large Soret's coefficients (20x 10-3 °C-1 of magnitude range). On the other hand, notable selective migration has been pointed out during thermogravitational effect concentration of LaCl3-YbCl3 mixture, ytterbium being characterized by a larger concentration ratio than that of lanthane.Les spectres de terres rares des minerais et des roches, utilisés comme guides de recherche sur l'origine des solutions hydrothermales minéralisantes, peuvent avoir été influencés par des phénomènes de thermodiffusion. L'étude expérimentale présentée montre le comportement thermogravitationnel de solutions simples de lanthanides (La(NO3)3 et Ce(NO3)3) imprégnant un milieu poreux. Ces deux sels semblent être particulièrement sensibles à la thermodiffusion puisqu'ils possèdent des coefficients de Soret élevés (de l'ordre de 20 x 10-3 °C-1). D'autre part, une migration sélective a pu être mise en évidence au cours de la concentration par effet thermogravitationnel d'un mélange de LaCl3 et YbCl3 où l'ytterbium subit un rapport de concentration plus élevé que celui du lanthane.Costesèque Pierre, Sempère Rodolphe.

Etnografia e fotografia: reflexões sobre as fotografias etnográficas de Pierre Fatumbi Verger
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas. Programa de Pós-graduação em Antropologia Social, Florianópolis, 2009A relação entre a fotografia e a etnografia nos estudos da Antropologia, apesar de antiga e densa, é incerta e complexa. Se por um lado a fotografia é a cada dia mais utilizada nos trabalhos antropológicos, por outro sua potencialidade como algo além da ilustração e de uma técnica de interação com o Outro é pouco explorada. A partir do exemplo, do legado, da trajetória de vida e, principalmente, da obra de Pierre Fatumbi Verger, esta pesquisa se dedica a analisar essa relação. Francês radicado na Bahia na década de 1940, Verger é conhecido mundialmente tanto por seu trabalho como fotógrafo quanto pelas suas pesquisa etnográficas. Há, entretanto, uma indefinição quanto à razão desse reconhecimento, e examinar as suas razões oferece um profícuo campo de reflexão sobre a pesquisa etnográfica, especialmente quando relacionada ao universo das imagens fotográficas. A Fundação Pierre Verger é a instituição que atualmente abriga o acervo do fotógrafo-etnógrafo e onde foi realizada a pesquisa de campo através da qual, aliada à leitura de fotografias relacionadas ao candomblé em suas manifestações na África e na Bahia, foi criada uma metodologia de análise das fotografias que privilegia as interações e os diálogos como espaço de construção de definições sobre a etnografia. Pelo contato com a Fundação, seus freqüentadores e o acervo fotográfico ali disponibilizado, esta pesquisa pretende refletir sobre a etnografia e a construção de um olhar etnográfico em relação direta com o exercício da fotografia.The relationship between photography and ethnography in anthropological studies, albeit ancient and deep, is uncertain and complex. Photography has been increasingly used in anthropological researches but it´s potencial as something beyond illustration and it´s interaction with the Other as a technique is very little explored. This research is dedicated to the analysis of this relationship by taking the work of Pierre Fatumbi Verger, his life and legacy. A French man, rooted in Bahia, Brasil, in the decade of 1940, Verger is known worldwide for his work as a photographer as well as for his etnographic studies. However, the reason of this recognition is undefined and examining the reason for these indefinitions can be a fruitful field of reflection concerning ethnographic researches, especially when related to the photographic universe. The Pierre Verger Foundation is the institution that hosts his photographic and ethnographic collection and it´s also where the field research of this work took place. Through the field research combined with the readings of photographs related to candomblé and it´s manifestations in Africa and Bahia, a photographic analysis methodology was created that privilege interaction and dialogue as a way to build definitions about ethnography. By the contact with the Foundation, it´s users and it´s available photographic collection, this research intends to reflect about the ethnography and the creation of an ethnographic view in direct relation to the exercise of photography
