Texto completoYtterbium lasers are widely used for short pulse generation, in particular for dual-comb spectroscopy. In this thesis work, we experimentally developed specific laser architectures for ytterbium-doped solid-state lasers, such as: Yb:YAG, Yb:Lu:YAG, Yb:Na:CNGG and Yb:CaF_2. In these quasi-isotropic active media, two eigenstates with orthogonal polarizations can oscillate simultaneously, generating two pulse trains that can be synchronous or asynchronous, depending on the type of cavity architecture. We first show that the orientation of the pump polarization is an effective tool of power control in bipolarized ytterbium lasers. The experimental results obtained are then compared with a two-mode rate-equation model taking into account the pump-induced gain anisotropy and the cross-saturation in the active medium. Secondly, we experimentally demonstrate a dual frequency comb with synchronous pulse trains in Yb:YAG and Yb:Lu:YAG bipolarized passive mode-locked lasers containing two intracavity quarter-wave plates. Finally, the achievement of an asynchronous dual-frequency comb in the Yb:YAG laser, as well as the tunability of the repetition rates, has been demonstrated
Fourier, Martine. "La violence de l'orientation ou la double peine des familles populaires". Paris 8, 2005. http://www.theses.fr/2005PA083030.
Texto completoThis research-action relates the disqualification of the popular families in school orientation and the professional integration of their children. Not being well-informed, those families feel school orientation as a source of social inequality which leads to early school exclusion. The word "double peine" (double punishment) represents both the exclusion from the school area and from a future social integration, in contradiction with the official educational policies, which aim at massive access to knowledge. Those parents, who cannot no longer transmit their skills, which became obsolate, are blame for their children's scholar and professional failure. The tools, the film and its documents, built from interviews collectives and individuals, were meant to bring those families to be both subjects and actors in those processes of orientation and professional integration

Texto completoThe purpose of the present Master s dissertation is to study the path followed by Peirce in the working up of his concept of belief, from the antecedents that determined it, up to the formulation of the pragmatist maxim. Along this study we shall consider, among other issues, the new role established for the doubt, which for Peirce is the opposite of belief, the importance of the scientific method of fixing belief and Peirce s critique of cartesianism. This critique will also be compared to Kant s critique of dogmatism and skepticism
O intuito desta dissertação de mestrado é o de estudar o itinerário seguido por Peirce na elaboração do seu conceito de crença, desde os antecedentes que o determinaram, até a influência deste conceito na formulação da primeira máxima do pragmatismo. Nessa trajetória examinaremos, entre outros pontos, o novo papel estabelecido para a dúvida, que para Peirce é o oposto da crença, a importância do método científico na fixação da crença e a crítica de Peirce ao cartesianismo. Será também traçado um paralelo entre essa crítica e a crítica de Kant ao dogmatismo e ceticismo

Texto completoThe objective of the thesis is to ascertain whether the rules wich govern appeals against verdicts and sentences give the convict a genuine recourse which assures that person the principle and the amount of the sentence are each well-founded. The function of the criminal appeal system is surveyed through historical and juridical data of its mechanisms ans complemented with a case study : the meticulous reading and study of 794 judgments from the appeal court of Lyon, during the period of 1. 1. 1988 to 30. 6. 1988, concerning repressive decisions against 1015 accused persons. This study permitted comparisons in relative termes between sentences by courts of first instance and the appeal court and an evaluation of the effects of the judicial pronouncements. The thesis thus proposes an explanation of the scarcity of appeals from judgments of police and magistrates courts. The combinaison of rules which define the pwers of the public prosecution and the mandate of appeal judges dissuades the accused from appealing against the sentence. Lodging an appeal constitues a risk, rather than a chance for the convict

Texto completoExpulsion or deportation constituted a privileged punishment prior to the modern prison, whose advantage was the definite exclusion of the individual without having to deal with his body. This punishment reappears as a new strategy of social control and of surplus world population management, particularly regarding foreigners in developed countries. The French model of expulsion of foreigners was based on an administrative device presented as a hygienic and tidy system, symbolized by the administrative retention centers. By means of a six-month-ethnographic study carried out at two retention centers near Paris, we analyze this topic with an empirical inductive approach, in which the characteristics and functioning of the displayed instruments are studied, mainly, the confinement of foreigners in administrative retention centers, so as to understand the impact of migratory control practices and policies on both the individuals and on the construction of the French society. In addition, we analyze forced return as an extension of the penal system whose informal objectives transcend effective deportation and aim to establish a device for the control of the migrant population in general

Texto completoFive to 10% of breast cancers are linked to a genetic predisposition. The management of patients at risk requires a good definition in the risk of cancer. The identification of causal molecular alterations in each of these families is a key issue in medical care. Two genes, BRCA1 and BRCA2, are related with the greatest susceptibility to breast cancer and ovarian cancer since the mid-1990s, accounting for about 15% of hereditary forms. Molecular analysis of these two genes is now routinely performed for the detection of nucleotide variations and more recently large rearrangements which have improved the detection rate of deleterious mutations. However, for more than 85% of families, no mutation explains familial aggregation or unusual young age of breast cancer onset. In this context, my thesis aimed at testing several hypotheses to explain the risks of breast cancer observed in families without any identified mutations in the BRCA1 and BRCA2 genes. We investigated some mechanisms of genic rearrangements rarely explored for BRCA1 and BRCA2 genes, and finally investigated other candidate genes, especially CDH1 gene and eight other genes involved in double-strand DNA repair. We have better characterized some rearrangements in the BRCA1 and BRCA2 genes. Finally, we applied RNA quantitative approaches to better assess the impact from variants of unknown significance and detected rearrangements. Initially, we developed and validated new technical approaches for detection and characterization such as dedicated CGH-array, qPCR-HRM and molecular combing. Rare large germline rearrangements and their frequency in eleven candidate genes for susceptibility to breast cancer were studied among 472 families negative by routine testing for BRCA1 and BRCA2 genes. Of these 11 genes, we conclude that genic rearrangements are found then mainly in the BRCA1 and BRCA2 genes, and to a lesser extent in the CHEK2 gene. We were able to describe two large intronic deletions and one duplication for the CDH1 and BARD1 genes, opening new perspectives on the regulation of their alternative transcript. In particular, we described the wide diversity of new rearrangements involving the 5' region of the BRCA1 gene. Then, it is necessary to validate and interpret those new events. Our transcript analysis described a new exonic variant causing the splice deletion of exon 23 in BRCA1 gene. We have developed tools to validate an in-frame large rearrangement of BRCA2 exon 3 with some transcript quantitative approaches and disease cosegregation.Finally, less than 1% of new rearrangements have been identified. This work is instructive for further investigations to establish molecular etiology in those families with breast cancer predisposition. Not only by applying new technologies, it is necessary to develop other strategies based primarily on quantifying effects of these alterations on transcription and traduction. However, it still lacks many links to explain the heritability of breast cancer. The combination of new candidate genes studies and the advent of high-throughput sequencing are expected to give a better vision of pathobiological phenomena related to the breast cancer predisposition
Koukezian, Thomas. "Sanction pénale sanction disciplinaire". Thesis, Rennes 1, 2014. http://www.theses.fr/2014REN1G018.
Texto completoDeux thèses s’affrontent concernant les liens qu’entretiennent la sanction pénale et la sanction disciplinaire. Une première conception considère que la sanction disciplinaire est distincte de la sanction pénale. Elle en diffère tellement qu’on ne saurait les rapprocher. L’autre conception, plus actuelle, considère que la sanction disciplinaire est une variété de la sanction pénale, qui la supplée ou la double, et qui obéit, en partie du moins, à des principes communs. La deuxième conception semble évidemment plus en phase avec la réalité. Cependant, cette façon d’entrevoir ces deux matières ne fait point l’unanimité. En considérant la sanction disciplinaire comme une fraction de la sanction pénale, comment entrer dans une telle considération devant le principe d’indépendance qui tient à distance les deux sanctions ? Et, si ce principe tient à distance les deux sanctions, c’est donc qu’il existe un domaine propre à chacune d’elles et une frontière entre ces deux domaines. L’étude consacrée aux sanctions pénales et disciplinaires se propose de tracer une frontière lisible entre ces deux sanctions et de mettre en lumière les caractéristiques peu connues de la sanction disciplinaire

Texto completoSecurity measures are at the heart of the current criminal policy, even though they raise a number of questions. Their place is very uncertain in French law, which has opted for a "single-track system", comprising only penalties, in the interest of simplification. Though, alongside the penalties, there are some security measures that are not always recognised as such, to the detriment of the coherence of the positive law. German law, on the contrary, has adopted a “dual-track system”, where penalties and security measures coexist within the criminal code. This system offers the advantage of recognizing the specificities of the security measures, which are not based on the guilt of the offender, but on his degree of danger. Although the distinction between the two categories of criminal sanctions is not an easy one, because of the areas of convergence, the two concepts cannot simply be treated as being the same. This comparative study of the emergence and the autonomy of the security measures concludes that a dualism of criminal sanctions should be introduced to the French criminal code with a complete own legal regime for the security measures, separate from the penalties’ regime, but in accordance with the basic principles of the criminal law

Texto completoLe phénomène de l'expulsion est, par définition, transnational et pousse à une coopération accrue des Etats. Dès lors, la mise en place d'un corpus minimal de droits, assorti des garanties procédurales permettant d'en assurer l'effectivité, est une nécessité d'autant plus pressante. Les organes internationaux de contrôle, à l'instar de la Cour européenne des droits de l'Homme, cherchent ainsi à interpréter favorablement les conventions applicables à cette matière afin de répondre à ce besoin.
Un dépassement de cette approche initiale, attachée au concept de nationalité, semble toutefois aujourd'hui nécessaire. A cet égard, l'Union européenne pourrait constituer un cadre juridique idéal pour la création d'un statut de “quasi-national” et l'autonomisation de la notion de citoyenneté européenne.
