O presente trabalho investigou a viabilidade do uso da técnica da dupla-camada, visando estabelecer adequados procedimentos de soldagem de reparo para o aço 9Cr-1Mo Grau P9, que permitissem dispensar o tratamento térmico pós-soldagem (TTPS). Por meio de testes de simples deposição sobre chapa do metal de base previamente temperado (e não revenido) foram levantadas as condições ideais para a realização do reparo. O aço 9Cr-1Mo apresentou uma faixa de revenimento que representa cerca de 80% da extensão da ZAC endurecida. Em função disso, o calor gerado pela segunda camada não foi suficiente para tratar termicamente a ZAC endurecida da primeira, sendo necessário realizar um passe adicional de revenido com tocha TIG autógena. Nessas condições, conseguiu-se tratar totalmente a ZAC remanescente e se obter no estado como-soldado uma resistência ao impacto similar à do metal de base. Entretanto, os metais depositados com os consumíveis disponíveis comercialmente apresentaram no estado como-soldado uma tenacidade muito baixa, o que implica na necessidade de desenvolver eletrodos especiais que possam ser aplicados na soldagem de reparo sem TTPS.

The main objective of this Thesis was to unravel the mechanisms allowing the activation of the molecular engine driving entry into M-phase in eukaryotic cells: MPF (M-Phase promoting Factor). For this purpose, meiotic divisions of the Xenopus oocytes were selected as a model system. Xenopus oocytes are naturally arrested in prophase of the first meiotic division. After progesterone stimulation, they complete the first meiotic division, form a metaphase I spindle and resume the first meiotic division with the extrusion of the first polar body. They immediately enter the second meiotic division by the formation of a metaphase II spindle and arrest at this stage until fertilization. This process depends the tight regulation of MPF activity (M-phase promoting factor), a complex between Cyclin B and the Cyclin-dependent kinase, Cdc2. Progesterone-triggered meiosis resumption ultimately leads to conversion of pre-MPF (a stockpile of inactive MPF due to two inhibitory phosphorylations, on Thr14 and Tyr15) into active MPF by an auto-amplification mechanism. MPF activation through removal of the inhibitory phosphorylations, is controlled by the activities of the Ccd25 phosphatase and the counteracting Myt1 kinase. The main results of this work are : 1) Myt1 function is required to maintain prophase I arrest in oocytes and Myt1 inhibition is an early event of meiosis resumption, controlled by neo-synthesized Cyclins, thus newly formed Cdc2/Cyclin B complexes. We propose a model in which the significant upregulation of Cyclin B synthesis following progesterone stimulation produces a small population of active Cdc2-Cyclin B, which is responsible for early Myt1 inhibition; this change in the balance between Cdc25 and Myt1 ensures rapid and complete conversion of pre-MPF into active MPF. 2) We then studied the implication of Cks proteins, Cdk-associated proteins, in the resumption of meiosis. We showed that the Xenopus Cks homolog Xe-p9 is present in oocytes and associated to a special fraction of free Cdc2, carrying the activating phosphorylation on Thr161. Furthermore, a functional approach allowed us to establish that Xe-p9 protein has an essential role in Xenopus meiotic M-phase entry. Overall our results led us to propose a model in which Cks-bound Cdc2, and already phosphorylated on Thr161, associates with newly synthesized Cyclins and the resulting active and ready-to-use MPF molecules act as the molecular trigger of meiosis re-entry

The central theme of the thesis concerns the exploitation of radio tracking measurements for the development of planetary ephemerides, in particular, applied on two research topics: 1) the analysis of navigation data of Cassini mission to enhance the ephemeris of Saturn and increase our knowledge of the outer solar system; 2) the simulation of BepiColombo measurements collected during the orbital phase at Mercury, for assessing their contribution on the Intégrateur Numérique Planétaire de l’Observatoire de Paris (INPOP) planetary ephemerides.The first research aims at reprocessing Cassini radio tracking data by exploiting the current knowledge of the Saturnian system developed throughout the mission, i.e. the availability of accurate satellite ephemerides and precise gravity solutions for Saturn, Titan and the other major moons. This allows the production of more precise normal points, which are able to constrain the orbit of the planet at meters-level for 13 years (almost half of its revolution) and to provide invaluable insights on the mass of the Kuiper belt. The results show a reduction of a factor 5 on normal points uncertainties with respect to previous analyses, providing tighter constraints on the acceptance regions of planet 9.The second research topic focuses on the production of realistic normal points derived from the end-to-end simulation of BepiColombo Mercury Orbiter Radio-science Experiment (MORE). The uncertainties of the normal points are deduced from the mapped covariance of the spacecraft state. The derived measurements are then processed with the INPOP weighted-least squares filter to quantify the achievable constraints on ephemerides and relativistic parameters

This work explores mechanical properties, structural evolution, and mechanism of creep-life enhancement for widely used P9 heat-resistant steel.The 17-year-on-site used P9 alloy exhibit a higher tensile strength and a smaller elongation than the new P9 alloy from room temperature to 700oC.The P9 alloy also displays a typical ductile feature with a significantly necking profile.The P9 alloy shows phase transition sequences of α-Fe(bcc)→(Ac1~858℃)→α+γ-Fe(bcc+fcc)→(Ac3~894℃)→γ-Fe(fcc) upon heating and γ-Fe(fcc) →(Ms~352℃)→martensite(bct)→(Mf~300 ℃)→martensite(bct) upon cooling.The new P9-alloy tube mainly contains ~73.5% ferrite phase (α-Fe) and ~26.5% carbide M3C.However,the used P9-alloy tube shows four crystalline phases including ~45.9% ferrite, ~14.5% martensite, ~37.5% cementite (M3C) and ~2.7% carbide M23C6.The creep test indicates that the used P9-alloy tube has a longer creep-life (or better anti-creep ability) than the new tube.Activation energies of atomic diffusion for the new and used tubes are respectively 252.45 and 345.87 kJ/mol, indicating a decreased diffusion capability in the used tube. This work suggests that martensite laths, lath boundaries,and precipitates (such as carbides) play important roles to inhibit creep-deformation in the P9-alloy steel.
