Ces travaux présentent une nouvelle méthode de conception dont l’objectif est de maximiser la durée de vie d’une structure en béton armé soumise à la carbonatation et de minimiser ses impacts environnementaux sur son cycle de vie. Cette approche est basée sur le développement d’un nouveau métamodèle de carbonatation couplé à une approche d’Analyse de Cycle de Vie (ACV). Une recherche de leviers d’actions sur la durabilité et les impacts environnementaux est réalisée via une combinaison de deux méthodes d’analyse de sensibilité. Nous définissons les leviers d’action comme étant des paramètres technologiques influents sur la durée de vie et/ou les impacts environnementaux de la structure en béton armé étudiée. Notre approche est appliquée au cas d’étude d’une structure en béton armé soumise à la carbonatation pour une durée de vie prévue de 100 ans située à Madrid, dans une classe d’exposition XC4 selon la norme EN 206-1. Pour ce cas d’application nous trouvons que la solution la plus durable et la plus respectueuse de l’environnent est celle utilisant du ciment CEM III/C, en minimisant le rapport eau sur ciment, l’épaisseur du béton d’enrobage, et la distance de la centrale fournissant le béton au site de construction. / This thesis presents a new design approach of which objective is to maximize service life of reinforced concrete structure and minimize its environmental impacts. This approach is based on the development of a new carbonation meta-model coupled with Life Cycle Assessment (LCA). A search for action levers on both durability and environmental impacts is conducted using a combination of two sensitivity analysis methods. We define action levers as technological parameters that are found influential on service life and/or environmental impacts for the studied reinforced concrete structure. Our approach is applied to a case study of a reinforced concrete structure design for a 100-year service life and located in Madrid within a XC4 exposure class according to the EN 206-1 standard. In that case study, we find that the most favorable solution for the RC structure is designed with the lowest cement content, water-to-cement ratio, concrete cover depth and distance from the concrete factory to the site, in association with the CEM III/C cement type.

This study is concerned with the administrative and educational contributions of Don Heath Morris to Abilene Christian College. The aim of this investigation is to ascertain the purposes of those who founded Abilene Christian College and to study the effects of the philosophy and work of Don H. 'Morris on the school. Attention is also given to the changes that occurred in Morris' philosophy as he adjusted to the vicissitudes of a growing college during a period when American higher education was making dramatic changes. Perhaps the outstanding quality of Don H. Morris as a college administrator was his persistence and single-mindedness in pressing for the achieving of the school's goals. He had the ability to see a goal clearly and to work toward it tirelessly. He never allowed the burdens of office that might have deterred a less committed and determined person to come between him and his devotion to the purposes of the school. Morris' basic philosophy of Christianity and Christian education was matured and intensified during his years at Abilene Christian College. His life was fulfilled in his work at Abilene Christian College, and Abilene Christian College bears the lasting impression of his personality and philosophy.

The goal of this thesis is to develop a financial analysis of Philip Morris CR a.s. in years 2002 -- 2007 for a potential investor. For a complex evaluation of the financial situation of the company the author used standard methods like horizontal and vertical analysis, balance rules, ratio indicators, schemes of indicators, Economic Value Added and also comparison with several companies from the industry. There is an important part on the macroeconomic and industry analysis at the beginning of the practical part of the thesis. At the end of the document there is an evaluation of the company with recommendations for investors.

La neurogenèse hippocampique adulte fait référence à la création de neurones durant la vie adulte dans le gyrus denté de l’hippocampe. Une décennie de recherche a démontré l’importance de cette neurogenèse chez l’adulte dans les processus de mémoire. En particulier, la neurogenèse adulte est nécessaire à l’apprentissage spatial et l’apprentissage spatial lui-même augmente la survie et accélère le développement d’une population de nouveaux neurones immatures. Cependant, l’implication de ces nouveaux neurones « sélectionnés » par l’apprentissage dans le devenir de la mémoire reste incertaine. En conséquence, le travail de cette thèse porte sur l’étude du rôle de ces nouveaux neurones dans les processus de mémoire spatiale à long terme résultants de l’apprentissage d’origine, comme la restitution et la reconsolidation de la mémoire. En effet depuis plus d’un siècle, on sait qu’un apprentissage n’induit pas immédiatement une mémoire stable. Les souvenirs sont tout d’abord fragiles, puis vont au fil du temps devenir stables et insensibles aux perturbations via un processus appelé «consolidation de la mémoire». Cependant ce processus n’est pas immuable ; les souvenirs établis peuvent à nouveau devenir labiles lorsqu'ils sont rappelés ou réactivés lors d’une restitution de la mémoire. Cette déstabilisation d’une mémoire consolidée nécessite alors un nouveau processus de stabilisation appelé « reconsolidation de la mémoire ». Depuis sa découverte, la reconsolidation a vivement intéressé le milieu de la recherche sur la mémoire et un nombre croissant d’études a cherché à comprendre les mécanismes sous-tendant cette reconsolidation, en particulier dans l'hippocampe. Étonnamment, le processus de reconsolidation n’a été que très peu envisagé dans le contexte de la neurogenèse hippocampique adulte.Nous avons tout d’abord mis au point un protocole de reconsolidation de la mémoire spatiale du rat dans le labyrinthe aquatique de Morris. Cela nous a permis de montrer que les néo-neurones nés avant l’apprentissage étaient activés lors de la reconsolidation de la mémoire spatiale, ce qui n’est pas le cas des neurones issus du développement précoce. Afin de pouvoir établir une relation de causalité entre néo-neurones et processus de reconsolidation, nous avons ensuite développé un outil basé sur la technique pharmacogénétique des DREADDs (Designer Receptors Exclusively Activated by Designer Drugs) couplés à un rétrovirus. Cet outil permet de marquer les néo-neurones à leur naissance et de les manipuler (inhiber ou stimuler l’activation) plus tard, lors des processus de mémoire à long terme. Nous avons observé que les néo-neurones immatures modifiés par l’apprentissage étaient non seulement activés par la reconsolidation mais également nécessaire à celle-ci, à l’inverse des néo-neurones matures au moment de l’apprentissage. Nous avons enfin montré que stimuler l’activité des néo-neurones au moment de la restitution de la mémoire améliorait les performances des rats dans le labyrinthe aquatique.Ensemble, ces résultats de thèse soulignent le rôle critique de la neurogenèse hippocampique adulte dans la stabilisation de la mémoire spatiale à long terme. / Adult hippocampal neurogenesis refers to the creation of neurons during adult life in the dentate gyrus of the hippocampus. A decade of research has demonstrated the importance of this adult neurogenesis in memory processes. In particular, adult neurogenesis is necessary for spatial learning and spatial learning itself increases survival and accelerates the development of a population of new immature neurons. However, the involvement of these new modified / promoted / amplified / selected neurons by learning in the fate of memory remains unclear. The work of this thesis focuses on the study of the role of these new neurons in the long-term spatial memory processes resulting from the original learning, such as retrieval and reconsolidation.For more than a century, we know that learning does not immediately induce a stable memory. Memories are fragile at first and then become stable and insensitive to interferences over time, through a process called “memory consolidation". However this process is not immutable; the established memories can become labile again when they are reactivated during memory recall. This destabilization of a consolidated memory requires then a new stabilization process called "memory reconsolidation". Since its discovery, the reconsolidation process has strongly interested the memory research community and a growing number of studies have sought to understand the mechanisms underlying this reconsolidation, particularly in the hippocampus. Surprisingly, the process of reconsolidation has rarely been considered in the context of adult hippocampal neurogenesis.We first developed a protocol for memory reconsolidation of spatial memory in the Morris water maze in rats. This allowed us to show that new neurons born before learning were activated during reconsolidation of spatial memory, which is not the case of the neurons generated during the early development. In order to establish a causal relationship between new neurons and reconsolidation, we developed a tool based on the pharmacogenetic technique of DREADDs (Designer Receptors Exclusively Activated by Designer Drugs) coupled with a retrovirus. This tool is used to tag new neurons at their birth and manipulate them (inhibit or stimulate their activation) later during long-term memory processes. We observed that the population of neurons that were immature at the time of learning are not only activated by but also necessary for reconsolidation, unlike new neurons that were mature at the time of learning. We have finally shown that stimulating the activity of new neurons during retrieval improves the performance of rats in the water maze.All together, these thesis results highlight the critical role of adult hippocampal neurogenesis in long-term spatial memory stabilization.

An edited transcription of the 1879 to 1887 diaries of Mary Lois Walker Morris (1835-1919). Mary Lois, a plural wife in 19th century Utah, went in and out of hiding between 1885 and 1887 to protect her husband Elias Morris from prosecution for illegal cohabitation. Her daily diaries culminate with the court trial of her husband for illegal cohabitation in September 1887. At the trial, she testified falsely, stating that she had been separated from her husband since the beginning of 1883, when in fact the couple did not separate until May of 1885. As a result, her husband was acquitted. Mary Lois and her husband Elias Morris, a prominent builder and businessman, were in a levirate marriage. Mary Lois had married Elias's brother John in 1852 and came across the plains to Salt Lake City with him. In 1855, when John lay dying, Mary Lois promised him that she would marry his brother Elias and raise up children that would belong to John in the hereafter. John's brother Elias agreed and took Mary Lois as a plural wife in 1856. Together, they had eight children, including LDS apostle George Q. Morris and Nephi Morris, a member of the Utah state legislature. Mary Lois's diaries contain detailed information about her own and her children's church meeting attendance, her time as the president of the Salt Lake 15th Ward Primary Association, her work as a milliner, her attitude toward polygamy and her interactions with her husband and children. Her diaries also give evidence of a rich cultural life that included attendance at many plays and concerts and contain conversations and interaction with many LDS people in Salt Lake City at the time. She records information about courtship patterns, housecleaning, leisure activities, reading material and other aspects of daily life in 19th century Utah. In addition, Mary Lois gives political commentary on the anti-polygamy conflict occurring around her and records her own experience in hiding during the raid.
